2012-06-01T01:51:03 < upgrdman> what benefit does turning on a gpio clock have? i used a gpio pin to blink and LED without turning on the clock and it seemed to work fine.
2012-06-01T01:51:21 < zyp> no, it does not work
2012-06-01T01:51:37 < zyp> so in your case it's likely already enabled
2012-06-01T01:52:26 < zyp> every peripheral that is not in use can be turned off (no clock) to save power, and peripherals that are turned off do not work

2012-06-01T03:38:07 < emeb> Yay! Free STM32F0 Discovery board.
2012-06-01T03:43:15 < emeb> http://www.st.com/internet/evalboard/product/253215.jsp
2012-06-01T03:43:32 < emeb> note the big blue button that says "FREE KIT"
2012-06-01T03:43:51 < emeb> Applied for mine last Thursday. Got it today.
2012-06-01T03:44:28 < emeb> And the board has STLINK V2.
2012-06-01T03:44:46 < emeb> tried it out with stlink-karlp : worked fine.
2012-06-01T03:45:52 < emeb> it really comes with a 0.1" perfboard w/ plated-thru holes. For what that's worth.
2012-06-01T03:47:26 < emeb> looks like 55 to me
2012-06-01T03:47:54 < emeb> hmmm - doubt that.
2012-06-01T03:50:31 < emeb> err - there's a regulator on the board so it can run from USB +5V
2012-06-01T03:50:42 < emeb> but the parts are 3.3V only AFAICT
2012-06-01T03:54:41 < emeb> Most 3.3V logic inputs can stand 5V if you include a current limit resistor. 10k or so should be fine.
2012-06-01T03:55:36 < emeb> what do you mean? 3.3V outputs driving 5V inputs needs no extra circuitry.
2012-06-01T03:57:19 < emeb> pg 35 of the User Manual has a 'schematic' for hooking the F0 Discovery to Arduino shields.
2012-06-01T03:57:52 < emeb> So maybe it is 5V tolerant... Ard Shields are nominal 5V I/O, right?
2012-06-01T04:02:32 < dongs> i bet yall buying this because of stlinkv2
2012-06-01T04:02:40 < dongs> and by buying i mean 'getting for free"
2012-06-01T04:02:50 < emeb> maaaaybe... :)
2012-06-01T04:03:00 < R2COM> free? what where
2012-06-01T04:03:25 < emeb>  http://www.st.com/internet/evalboard/product/253215.jsp
2012-06-01T04:04:09 < R2COM> you have to be part of company
2012-06-01T04:04:47 < emeb> Could be. I am. A buddy applied a couple days earlier than I and just put down self/hobby and got one too.
2012-06-01T04:05:26 < emeb> ST is winning at marketing lately.
2012-06-01T04:06:02 < dongs> k ordered mine
2012-06-01T04:06:09 < emeb> I've already put 1 product into production and started 2 more with their parts because of these low-cost devboards.
2012-06-01T04:07:11 < R2COM> is m0 lower grade device?
2012-06-01T04:07:14 < R2COM> than m4 right?
2012-06-01T04:07:46 < emeb> still has 32-bit regs tho, no?
2012-06-01T04:08:22 < dongs> flyback-: please stop talking nonsense out of your ass
2012-06-01T04:08:27 < dongs> cortex M0 is not 16bit.
2012-06-01T04:08:52 < emeb> but m3, m4 are thumb-only too.
2012-06-01T04:09:03 < emeb> yes
2012-06-01T04:10:29 < dongs> yes m3 and m4 are thumb only you fucknut
2012-06-01T04:11:23 < dongs> thats because you keep spreading bullshit
2012-06-01T04:11:27 < dongs> about stuff you dont even know
2012-06-01T04:11:31 < dongs> and make it sound authoritative

2012-06-01T04:11:47 < dongs> ???????????????
2012-06-01T04:11:55 < dongs> how the fuck does instruction set have anything to do with lunix
2012-06-01T04:12:12 < dongs> i mean i dont evne need to link to wikipedo for this but
2012-06-01T04:12:15 < dongs> http://en.wikipedia.org/wiki/ARM_Cortex-M
2012-06-01T04:12:34 < dongs> All four Cortex-M cores implement a common instruction subset that consists of: Thumb subset, Thumb-2 subset, and multiply. The Cortex-M0 and M1 include all older Thumb instructions, except new instructions (CBZ, CBNZ, IT) which were added in ARMv7-M architecture.
2012-06-01T04:12:49 < dongs> break "what" C code?
2012-06-01T04:14:55 < dongs> moar TROLLING by FLYBACK
2012-06-01T04:18:21 < dongs> dude they're all fucking 32bit
2012-06-01T04:18:31 < dongs> size of instruction has fuck all to do with the fact that the core is 32bit
2012-06-01T04:19:21 < dongs> I did
2012-06-01T04:19:26 < dongs> 10:11 < dongs> how the fuck does instruction set have anything to do with lunix
2012-06-01T04:25:19 < dongs> flyback-: if you havent coded since college what hte fuck are you doing here besides trolling.
2012-06-01T04:26:30 < dongs> got caught up on most of my fail projects maybe time to code for some fun

2012-06-01T07:00:31 < cjbaird> I've only done the two-wheeled floorbot kind of thing so far.
2012-06-01T07:01:21 < R2COM> good. send him to war.
2012-06-01T08:43:19 < R2COM> anyone can point to some sd-card related code for stm32f4? which one used and know it works?
2012-06-01T08:43:39 < R2COM> cant find anything on ST, seems they have simpler examples, not sd-card

2012-06-01T11:06:49 < dongs> used 4bit SDIO
2012-06-01T11:06:52 < dongs> not_hard
2012-06-01T11:06:52 < R2COM> dongs: which one you used?
2012-06-01T11:06:58 < R2COM> i mean which code
2012-06-01T11:07:01 < R2COM> where did you get it
2012-06-01T11:07:09 < dongs> do you mean filesystem? or hardware part? or?
2012-06-01T11:07:14 < dongs> filesystem = fatfs by elm"chan"
2012-06-01T11:07:15 < R2COM> source
2012-06-01T11:07:22 < dongs> there's tons of examples of using it with stm32

2012-06-01T11:09:15 < R2COM> dont get anything in that language

2012-06-01T11:12:16 < R2COM> i guess it just takes some time to study fat and write own stuff, but well..
2012-06-01T11:12:46 < dongs> well this board is a writeoff
2012-06-01T11:12:53 < dongs> the trace burned off the board for the most part
2012-06-01T11:12:58 < dongs> as i suspected not worth fixing
2012-06-01T11:13:40 < R2COM> which board??
2012-06-01T11:13:59 < dongs> 17:02 < dongs> http://i.imgur.com/WVVNQ.jpg lol
2012-06-01T11:14:01 < dongs> ths one.
2012-06-01T11:18:17 < R2COM> i see that zip contains ff folder, with all fat-fs related stuff
2012-06-01T11:18:38 < R2COM> so ill probably include it all, and grab main functions, see how it works later
2012-06-01T11:18:42 < dongs> yes, and original homepage is: http://elm-chan.org/fsw/ff/00index_e.html
2012-06-01T11:18:49 < dongs> which also has stm32 examples.
2012-06-01T11:22:23 < R2COM> hmm it can also work with ATA?
2012-06-01T11:22:37 < R2COM> but, there has to be a controller for that then..
2012-06-01T11:26:14 < zyp> fatfs should work with any block device
2012-06-01T11:26:38 < R2COM> well ok, but there must be a controller, a low level controller
2012-06-01T11:26:50 < zyp> you mean block device driver
2012-06-01T11:26:58 < zyp> that's not fatfs' responsibility
2012-06-01T11:27:05 < dongs> lunix device driver
2012-06-01T11:27:05 < R2COM> in a case of stm32 there is of course internal hardware responsible for sd-card related stuff
2012-06-01T11:27:26 < dongs> doesnt fsmc do ata
2012-06-01T11:27:30 < R2COM> and one cannot just add those pins to ATA drive
2012-06-01T11:27:44 < R2COM> not sure...if it does then ok
2012-06-01T11:27:51 < dongs> it does CE-ATA whatever teh fuck that is
2012-06-01T11:28:09 < dongs> IDE drives are deader than Lubunto on desktop
2012-06-01T11:29:06 < zyp> I haven't looked at fatfs, but I imagine it requires an API like «give me n bytes from offset x» and «write these n bytes to offset x»
2012-06-01T11:29:56 < zyp> and as long as you have something implementing that for whatever device you use, it's fine
2012-06-01T11:30:33 < R2COM> its routines do that...give me that from that offset
2012-06-01T11:30:50 < R2COM> but the way how its actually *done* is from low level controller
2012-06-01T11:30:59 < zyp> huh?
2012-06-01T11:31:16 < dongs> zyp: blocks, but yeah
2012-06-01T11:31:20 < R2COM> i mean, what you described is probably coded in the functions of fatfs already
2012-06-01T11:31:26 < dongs> i think it needs 512byte sectors
2012-06-01T11:31:37 < dongs> R2COM: you provide fatfs readblock() and writeblock()
2012-06-01T11:31:39 < dongs> it handles the rest.
2012-06-01T11:31:50 < zyp> right
2012-06-01T11:31:52 < dongs> for all it cares, you can allocate 30k of ram for a ramdisk and give it read/write pointers to that.
2012-06-01T11:32:25 < R2COM> right now i dont have enough time to fuck around with internals of fat
2012-06-01T11:32:32 < R2COM> otherwise it would make sense to write your own
2012-06-01T11:32:45 < zyp> would it really?
2012-06-01T11:32:54 < dongs> for bonus points, add ethernet, write a program in ruby to read/write bits from a file, then replace read/write block stuff wtih sending it across network.
2012-06-01T11:32:59 < R2COM> some people told me that there are many problems arising when using those libs when doing something critical
2012-06-01T11:33:01 < R2COM> yes
2012-06-01T11:33:12 < R2COM> i remember long time ago, i was using the Microchips sd-card routines
2012-06-01T11:33:18 < R2COM> i was designing some data logging application
2012-06-01T11:33:27 < dongs> thats because microchip shit sucks
2012-06-01T11:33:31 < dongs> fatfs has been around for years
2012-06-01T11:33:32 < R2COM> and, i noticed that under several conditions, it took longer time to write stuff
2012-06-01T11:33:36 < dongs> and pretty much every project uses it
2012-06-01T11:33:41 < R2COM> ok
2012-06-01T11:33:50 < dongs> and by project i mean even payware shit.
2012-06-01T11:33:54 < zyp> dongs, you're not a real man before you have support for iscsi on your mcu
2012-06-01T11:34:02 < dongs> o rite
2012-06-01T11:34:21 < R2COM> so, who developed fatfs?
2012-06-01T11:34:30 < dongs> < dongs> yes, and original homepage is: http://elm-chan.org/fsw/ff/00index_e.html
2012-06-01T11:34:35 < dongs> some animu-watching jap
2012-06-01T11:34:38 < R2COM> oh that same guy
2012-06-01T11:34:55 < dongs> different guy
2012-06-01T11:34:56 < dongs> but same shit
2012-06-01T11:35:09 < R2COM> interesting
2012-06-01T11:35:32 < R2COM> right now he is probably developing soft for future robots which would fight US isnt it
2012-06-01T11:36:45 < zyp> yea, you'd have to have fatfs on them, so you can just insert an sd-card with a list of targets

2012-06-01T12:09:20 < zyp> hmm, no can
2012-06-01T12:09:37 < zyp> would still have to go with F1 or higher for can I guess
2012-06-01T12:10:07 < dongs> no hardware divide on M0 either
2012-06-01T12:10:13 < dongs> so its a bit ghettoish

2012-06-01T12:16:28 <+izua> also, why use a dedicated controller?

2012-06-01T13:12:09 < zyp> right
2012-06-01T13:12:29 < zyp> well, you only told it to turn on the blue one, not turn off the others
2012-06-01T13:13:10 < upgrdman> ok but the orange and red LEDs are on the same port and didnt light up
2012-06-01T13:14:16 < zyp> what happens if you don't turn on the blue led?

2012-06-01T13:40:53 < zyp> right
2012-06-01T13:41:02 < zyp> that's two 16-bit parts of the 32-bit register BSRR
2012-06-01T13:41:09 < upgrdman> ok

2012-06-01T13:41:48 < zyp> the lower part of BSRR is the set-part, the higher part of BSRR is the reset-part
2012-06-01T13:42:05 < zyp> so BSRRL sets the output high, BSRRH sets the output low
2012-06-01T13:42:16 < zyp> the L and H in the names have nothing to do with the output levels

2012-06-01T13:43:46 < upgrdman> do you use arm-none-eabi-gdb? loading the .elf with "load x.elf" loads it into memory instead of saving it to flash. any idea how to get it to load the firmware into flash?

2012-06-01T14:02:42 < zyp> I'm using scons instead of make
2012-06-01T14:02:58 < zyp> except for that I'm using same toolchain
2012-06-01T14:05:49 < upgrdman> well i dont fully understand makefiles, but heres the short one i have been using http://pastebin.com/6s1WQZti ... try not to laugh ;) i'll have to read up on make and gc
2012-06-01T14:14:58 < zyp> IMO make is old and outdated, and doesn't really have any real advantages over scons
2012-06-01T14:16:31 < upgrdman> ok
2012-06-01T14:16:40 < zyp> your simple makefile builds everything in a single step, so it's not really utilizing the point of make
2012-06-01T14:16:49 < zyp> which is to rebuild only the parts that changed
2012-06-01T14:17:00 < upgrdman> i know
2012-06-01T14:17:27 < upgrdman> i'm going to have to give up on understanding my makefile and just use a proper one that i dont really understand ;)
2012-06-01T14:17:44 < upgrdman> i'll try some of karlp's stuff and look into libopencm3
2012-06-01T14:18:23 < zyp> or you could use scons instead of make ;)
2012-06-01T14:19:21 < zyp> it hides all the lowlevel complexity of dependency tracking and intermediate steps, and lets you just specify which output files you want from which input files
2012-06-01T14:19:29 < Laurenceb> it looks nice
2012-06-01T14:19:41 < Laurenceb> does it track changes in headers?
2012-06-01T14:19:45 < zyp> yes
2012-06-01T14:19:52 < Laurenceb> better than make then

2012-06-01T14:21:16 < Laurenceb> make is annoying, sometimes it tracks headers ok, sometimes not

2012-06-01T15:01:58 < upgrdman> when i moved from one house to another i contemplated keeping my server on by unplugging the UPS and keeping the box plugged into the UPS while driving.
2012-06-01T15:02:19 < upgrdman> but i decided to play it safe. bouncing in a car can't be good for hdd's

2012-06-01T16:28:53 < Tectu_> how does one calibrate a touchscreen without knowing math like matrixes etc

2012-06-01T16:31:23 < zyp> math is a tool, not knowing enough is like trying to build a house without having a hammer

2012-06-02T00:24:42 < FUZxxl> Hlloello!
2012-06-02T00:25:00 < FUZxxl> I have an stm32l discovery board.
2012-06-02T00:25:20 < FUZxxl> I use linux, I just started
2012-06-02T00:25:28 < FUZxxl> I accidentially overwrote the demo software.
2012-06-02T00:25:49 < FUZxxl> Does anybody know where I can get a blob of the original demo software to flash onto the device?
2012-06-02T00:25:59 < FUZxxl> flyback-: What do you mean?
2012-06-02T00:26:16 < FUZxxl> yeah
2012-06-02T00:26:23 < FUZxxl> There are some linux tools for this device.
2012-06-02T00:26:32 < FUZxxl> I actually don't have any of the WIndows tools installed.
2012-06-02T00:27:29 < FUZxxl> flyback-: Do you know where I can get a binary of those demo programs? The "firmware package" ships sources, but, lacking a Makefile, I wasn't able to compile them.
2012-06-02T00:28:12 < FUZxxl> Germany
2012-06-02T00:28:58 < FUZxxl> The problem is: The device is not mine. I tried one of the demos infrom the linux utils, but it apparently got flashed onto the chips
2012-06-02T00:29:14 < FUZxxl> All other demos did just run from RAM, just using gdb
2012-06-02T00:31:29 < FUZxxl> GDB apparaently sees no reason to ask if one overwrites the flash memory...

2012-06-02T00:43:23 < zyp> ah, right, just source
2012-06-02T00:44:33 < zyp> ah, no, there are compiled files for AN3413 and AN3964 in there
2012-06-02T00:45:27 < zyp> I guess it ships with one of those then?
2012-06-02T00:46:31 < zyp> yeah, databrief says it ships with AN3413
2012-06-02T00:46:59 < zyp> so you can just flash Projects/AN3413-Current_consumption_touch_sensing/Binary/STM32L-Discovery.hex from that package
2012-06-02T00:49:02 < Laurenceb_> its quite clever
2012-06-02T00:49:16 < Laurenceb_> it doesnt really have touch hardware
2012-06-02T00:49:33 < Laurenceb_> its abusing the analogue mux as a charge pump

2012-06-02T00:50:01 < FUZxxl> Do yo know how to flash it using gdb?
2012-06-02T00:50:43 < zyp> no, I've never flashed a .hex, can't you just load it like it were an .elf?
2012-06-02T00:50:53 < FUZxxl> let me try...
2012-06-02T00:52:14 < FUZxxl> Yeah! It works!!!

2012-06-02T00:56:12 < Laurenceb_> cool
2012-06-02T00:56:24 < FUZxxl> I want to check out what is possible with that board.
2012-06-02T00:56:37 < FUZxxl> I'm new to microcontrollers and such stuff.
2012-06-02T00:56:59 < FUZxxl> I just found out, the lcd demo  shipped with the texane package   is buggy.
2012-06-02T00:57:19 < FUZxxl> It always displays some random garbage inbetween and at the end.
2012-06-02T00:57:26 < zyp> lots of the texane demos are
2012-06-02T00:57:31 < FUZxxl> ANd if I change the string, it sometimes stops working...
2012-06-02T00:58:01 < FUZxxl> Well, it seems like he just took the lib from said package and implemented his lcd demo atop it.
2012-06-02T00:58:10 < zyp> likely
2012-06-02T00:58:10 < FUZxxl> That's why I wonder why it fails.
2012-06-02T00:58:25 < FUZxxl> I guess it's because of gcc "optimizing" away behavior...
2012-06-02T00:58:28 < Laurenceb_> the st stuff is known to have bugs
2012-06-02T00:58:44 < zyp> I don't have experience myself with them, but karlp claims they are pretty bad and that you're better off looking at other demos
2012-06-02T00:59:07 < FUZxxl> zyp: Where can I get demos?
2012-06-02T00:59:14 < FUZxxl> Is there a good tutorial about that stuff?
2012-06-02T00:59:34 < zyp> not that I know of, ask karlp
2012-06-02T00:59:41 < FUZxxl> I thought about implementing "Simon Says" as an excercise, o understand how it works.
2012-06-02T00:59:50 < zyp> he usually suggests something here and there, and then looking at libopencm3
2012-06-02T01:00:01 < FUZxxl> okay
2012-06-02T01:03:05 < FUZxxl> Do you know how to tell objcopy that the binary dump is ARM code?
2012-06-02T01:03:32 < zyp> I've done it before
2012-06-02T01:04:14 < zyp> you use -B with some value, IIRC
2012-06-02T01:04:19 < FUZxxl> Yeah.
2012-06-02T01:04:27 < FUZxxl> So, I have that .hex firmware file.
2012-06-02T01:04:36 < zyp> -B elf32-littlearm, or something like that
2012-06-02T01:04:44 < FUZxxl> I run the following command (from the summon-arm-toolchain package):
2012-06-02T01:05:17 < FUZxxl>  arm-none-eabi-objcopy -I ihex -B arm -O elf-little STM32L-Discovery.hex STM32L-Discovery.elf
2012-06-02T01:05:51 < FUZxxl> Well, if I run file on that elf file, it reports "unknown architecture"
2012-06-02T01:06:31 < zyp> what does readelf say?
2012-06-02T01:07:10 < FUZxxl> ABI: unknown, Machine: none
2012-06-02T01:07:37 < zyp> ah, right
2012-06-02T01:08:01 < zyp> well, just read the objcopy man page and try stuff until you get it right
2012-06-02T01:08:05 < FUZxxl> okay
2012-06-02T01:08:16 < zyp> I don't know anything more specific than what you already did
2012-06-02T01:09:38 < FUZxxl> okay. Thank you!
2012-06-02T01:10:42 < FUZxxl> Is there a tutorial on how IO works with ARM?
2012-06-02T01:11:10 < FUZxxl> I'm especially curious about the lcd. It blinks even if the processor is haltet remotely...
2012-06-02T01:11:41 < Laurenceb_> yeah thats as just the core is halted
2012-06-02T01:12:38 < FUZxxl> okay...
2012-06-02T01:13:14 < FUZxxl> But, what controls the panel than? The connection scheme didn't show any other controller for it (did I miss something?)
2012-06-02T01:13:55 < zyp> I guess stm32l contains an lcd controller?
2012-06-02T01:14:51 < zyp> yep
2012-06-02T01:14:57 < FUZxxl> stm32l - s that the processor or the board?
2012-06-02T01:15:10 < zyp> that is the microcontroller chip on the board
2012-06-02T01:15:17 < zyp> or rather, the microcontroller family
2012-06-02T01:15:46 < zyp> I suggest you have a look at the stm32l reference manual
2012-06-02T01:15:47 < zyp> http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/REFERENCE_MANUAL/CD00240193.pdf
2012-06-02T01:16:49 < zyp> remember that a microcontroller is more than just a cpu, it's pretty much a one-chip-computer, containing both flash, ram and various other peripherals
2012-06-02T01:17:20 < zyp> and even if you halt the cpu, it's just the cpu that gets halted
2012-06-02T01:18:34 < zyp> (some peripherals can be configured to halt along with the cpu to assist debugging, but generally they run fully independent of the cpu)
2012-06-02T01:18:49 < FUZxxl> okay.
2012-06-02T01:19:02 < FUZxxl> Thank you for the information!
2012-06-02T01:19:11 < zyp> no problems
2012-06-02T01:21:54 < FUZxxl> If I'd try to do that LCD stuff on my own (w/o that library), would that be similiar to shooting yourself in the foot?
2012-06-02T01:22:10 < zyp> likely not
2012-06-02T01:22:20 < zyp> let's have a look at chapter 15 in that reference manual
2012-06-02T01:23:28 < zyp> ok, looking at the registers of the lcd controller, it looks very simple
2012-06-02T01:24:06 < zyp> a few control registers to select mode of operation, and then just a bunch of registers containing the value you want for each segment
2012-06-02T01:24:52 < FUZxxl> Sorry, my internet is a little it slow right now (24 kb/s)...
2012-06-02T01:25:18 < FUZxxl> I haven't yet received the manauual.
2012-06-02T01:25:34 < zyp> do you have any experience from other microcontrollers?
2012-06-02T01:25:59 < FUZxxl> Nope.
2012-06-02T01:26:12 < zyp> do you understand memory-mapped registers? :p
2012-06-02T01:28:45 < FUZxxl> I understand what memory mapping is and that certain magic addresses are mapped to hardware functions
2012-06-02T01:29:17 < zyp> good
2012-06-02T01:29:35 < zyp> every peripheral have it's own block of memory mapped registers
2012-06-02T01:29:51 < FUZxxl> okay.
2012-06-02T01:29:58 -!- Steffann [~Steffanx@ip4da726ae.direct-adsl.nl] has quit [Ping timeout: 244 seconds]
2012-06-02T01:30:09 < FUZxxl> The spec probably gives some information about the addresses...
2012-06-02T01:30:32 < zyp> each peripheral have it's own chapter in the reference manual, and the last section of each chapter contains a description of all those registers
2012-06-02T01:30:52 < zyp> so if you are working directly with the peripheral registers, that's where you find the info you need
2012-06-02T01:31:04 < FUZxxl> okay. That looks like what I need.
2012-06-02T01:31:49 < FUZxxl> Does the board also have some things to implement a sleep() like functionality without needing to use empty loops?
2012-06-02T01:32:03 < zyp> yes
2012-06-02T01:32:19 < FUZxxl> That's good.
2012-06-02T01:32:40 < zyp> the cpu core has a systick timer, so you can use that to wait until it has reached a certain value
2012-06-02T01:35:41 < zyp> http://cgit.jvnv.net/suzumebachi/tree/os/time.h?h=stm32f4 <- in my application I'm doing it like this
2012-06-02T01:35:59 < FUZxxl> okay
2012-06-02T01:36:08 < zyp> tick() is called once every millisecond, and increases systime which is a millisecond counter
2012-06-02T01:36:45 < zyp> and when sleep() is called, it calculates which value it would have to wait until, and remains in the loop until that value is reached
2012-06-02T01:37:04 < zyp> I'm doing multithreading, so Thread::yield() switches to another thread while sleeping
2012-06-02T01:37:49 < FUZxxl> okay
2012-06-02T01:38:16 < zyp> if you don't have other threads, i.e. nothing else to do while waiting, you could just have an empty loop body there
2012-06-02T01:38:21 < FUZxxl> Wait... this is C++ code.
2012-06-02T01:38:28 < zyp> yes, I'm writing C++
2012-06-02T01:38:43 < FUZxxl> How does it look like on a lower level? Is your code hiding hardware details?
2012-06-02T01:38:52 < zyp> it would be the same in C, except you can't wrap it up in a class like that
2012-06-02T01:39:43 < zyp> that particular class has all methods static, so it doesn't really do anything except provide a namespace and give systime private visibility
2012-06-02T01:39:58 < FUZxxl> okay.
2012-06-02T01:40:36 < FUZxxl> How can one ensure that tick() is called every millisecond?
2012-06-02T01:40:47 < zyp> it's done by the systick interrupt
2012-06-02T01:41:14 < zyp> http://cgit.jvnv.net/suzumebachi/tree/hal/fault.cpp <- which in my code is currently located here
2012-06-02T01:41:14 < FUZxxl> okay...
2012-06-02T01:41:19 < FUZxxl> I'm confused
2012-06-02T01:42:18 < zyp> I'm configuring the systick timer to give me an interrupt every millisecond, which calls tick() that serves as the base for the rest of the timing stuff
2012-06-02T01:42:32 < FUZxxl> okay.
2012-06-02T01:42:35 < FUZxxl> That makes sense.
2012-06-02T01:42:59 < zyp> it might not be the best way to do stuff, but currently it works for me
2012-06-02T01:43:35 < Thorn> Use __sync_lock_test_and_set() for spinlocks on ARM, if available. This function replaces our previous use of the SWPB instruction, which is deprecated and not available on ARMv6 and later. Reports suggest that the old code doesn't fail in an obvious way on recent ARM boards, but simply doesn't interlock concurrent accesses, leading to bizarre failures in multiprocess operation.
2012-06-02T01:43:43 < FUZxxl> Well, it's certainly better than spinning loops
2012-06-02T01:43:44 < Thorn> ^^ from postgresql release notes
2012-06-02T01:44:06 < zyp> Thorn, huh? :p
2012-06-02T01:44:51 < Thorn> looks like somebody failed in a pretty spectacular fashion
2012-06-02T01:44:57 < zyp> Thorn, __sync_lock_test_and_set is probably based on ldrex/strex
2012-06-02T01:45:03 < zyp> http://cgit.jvnv.net/suzumebachi/tree/os/mutex.h <- similar to this
2012-06-02T01:45:36 < FUZxxl> zyp: Is there also an instruction listening included in the spec you linked?
2012-06-02T01:45:53 < zyp> FUZxxl, no, that's available from ARM
2012-06-02T01:46:12 < zyp> the cpu in stm32l is a normal cortex-m3
2012-06-02T01:46:31 < zyp> actually, I think ST has it's own document for that too
2012-06-02T01:46:47 < zyp> http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/PROGRAMMING_MANUAL/CD00228163.pdf <- here it is
2012-06-02T01:47:27 < FUZxxl> Thank you!
2012-06-02T01:47:48 < FUZxxl> I love assembly programming, but I always fail to find a plain instruction listening.
2012-06-02T01:48:37 < FUZxxl> It's crazy... When I learned amd64, there were lots of tutorials, but none actually gave a full detailed listening of all instructions (the only thing I needed)
2012-06-02T01:48:38 < zyp> then you need to get better at locating/reading documentation ;)
2012-06-02T01:48:55 < FUZxxl> zyp: Yeah. That one's difficult.
2012-06-02T01:49:21 < zyp> oh, intel provides documents containing all x86/64 instructions
2012-06-02T01:49:38 < zyp> I got a copy of them somewhere
2012-06-02T01:50:03 < zyp> those are a few thousand pages each, and the instruction listing is so huge that it's split across two of those :p
2012-06-02T01:50:50 < FUZxxl> zyp: And that's the problem. Why can't they make developer-friendly html-documents with proper indices and an explanation of the semantics that is actually understandable.
2012-06-02T01:51:06 < FUZxxl> Same thing for the docu for their intrinsics.
2012-06-02T01:51:26 < Thorn> I had those intel docs somewhere too. they should be issued to anybody who thinks ARM ARM is too complex to understand and/or use
2012-06-02T01:51:28 < zyp> http://www.intel.com/content/www/us/en/processors/architectures-software-developer-manuals.html <- here they are
2012-06-02T01:51:46 < BrainDamage> I prefer pdf docs to html docs
2012-06-02T01:51:51 < zyp> oh, looks like it got split into three now; 2A, 2B, 2C
2012-06-02T01:51:52 < BrainDamage> and pdf can still have indices
2012-06-02T01:51:54 < FUZxxl> I have them on my machine. But.. you know... I also have other hobbies
2012-06-02T01:52:06 < zyp> :)
2012-06-02T01:52:30 < zyp> I've played with writing a small kernel for x86 before
2012-06-02T01:53:25 < zyp> it's a bit harder than cortex-m, virtual memory adds a whole new level of complexity :p
2012-06-02T01:53:31 < FUZxxl> zyp: Well, I guess you don't need to understand what VPERMPD does for writing a kernel...
2012-06-02T01:53:52 < FUZxxl> zyp: I understand that actually pretty good.
2012-06-02T01:54:00 < FUZxxl> I did MMIX as an introduction.
2012-06-02T01:54:13 < FUZxxl> Knuth did a good job there. That thing has a nice MMU
2012-06-02T01:54:33 < zyp> MMIX?
2012-06-02T01:55:09 < FUZxxl> MMIX is an ISA developed by Donald E. Knuth for his "The Art of Computer Programming" series.
2012-06-02T01:55:19 < zyp> ah
2012-06-02T01:55:21 < FUZxxl> It's a pretty nice RISC CPU with some unique features.
2012-06-02T01:55:29 < FUZxxl> Streamlined to be educative.
2012-06-02T01:55:44 < FUZxxl> It has some crazy things like register renaming as a calling convention
2012-06-02T01:56:33 < FUZxxl> Oh nice... the Programmers' manual is just 150 pages...
2012-06-02T01:56:37 < FUZxxl> That's cool.
2012-06-02T01:56:49 < zyp> it just describes the cpu
2012-06-02T01:56:58 < zyp> and cortex-m3 is a pretty simple architecture
2012-06-02T01:57:40 < FUZxxl> yeah...
2012-06-02T01:57:45 < FUZxxl> So nice...
2012-06-02T01:57:51 < FUZxxl> How many different instructions?
2012-06-02T01:58:22 < zyp> yes, the simplicity of the arm and thumb ISA is the beauty of the ARM architecture :p
2012-06-02T01:58:26 < FUZxxl> yeah.
2012-06-02T01:58:29 < zyp> don't knwo
2012-06-02T01:58:32 < Thorn> who cares about the number of instructions
2012-06-02T01:58:40 < FUZxxl> Can I do things like thumb interworking with that processor?
2012-06-02T01:58:50 < zyp> I don't know them all, I just refer to the reference if i need to work with them
2012-06-02T01:58:55 < zyp> thumb interworking?
2012-06-02T01:59:11 < zyp> is that switching between arm and thumb?
2012-06-02T01:59:11 < FUZxxl> You can mix thumb and non-thumb instructions on some modells.
2012-06-02T01:59:12 < Thorn> FUZxxl: no ARM mode -> no interworking
2012-06-02T01:59:19 < zyp> what Thorn said
2012-06-02T01:59:28 < FUZxxl> Thorn: It only has thumb instructions???
2012-06-02T01:59:33 < zyp> cortex-m only implements thumb
2012-06-02T01:59:37 < FUZxxl> okay.
2012-06-02T01:59:39 < Thorn> -2
2012-06-02T01:59:40 < FUZxxl> Nice to know.
2012-06-02T01:59:45 < Thorn> quiz: what ARM CPU doesn't support ARM ISA?
2012-06-02T02:00:11 < zyp> thumb is also an ARM ISA, but not _the_ ARM ISA :p
2012-06-02T02:00:35 < FUZxxl> okay.
2012-06-02T02:00:46 < FUZxxl> I'm confused.
2012-06-02T02:01:14 < zyp> oh, and trying to switch to switch to arm mode will cause a UsageFault, due to INVSTATE, rumor has it that a lot of hairs have been pulled due to that :p
2012-06-02T02:01:20 < zyp> -switch to
2012-06-02T02:01:57 < Thorn> blx -> branch with link and crash
2012-06-02T02:02:09 < zyp> mostly happens if your toolchain is broken so it links to arm-libraries rather than thumb-libraries
2012-06-02T02:02:22 < FUZxxl> hehe
2012-06-02T02:04:42 < zyp> also, I like you, you sound skilled… stay, learn and start helping others ;)
2012-06-02T02:04:59 < Thorn> btw cortex-m1 is actually free for actel fpgas
2012-06-02T02:05:26 < FUZxxl> Thank you!
2012-06-02T02:05:51 < FUZxxl> You know, I'm just a highschool student. I got this device from somebody who did Atmels before.
2012-06-02T02:06:19 < FUZxxl> He want's me to find out for him how to do lowlevel stuff on this thing...
2012-06-02T02:06:41 < FUZxxl> Pretty interesting, this device.
2012-06-02T02:06:44 < FUZxxl> One more question:
2012-06-02T02:07:01 < FUZxxl> The discovery board features a six-digit 14-segment display.
2012-06-02T02:07:30 < FUZxxl> The chip's spec only says something about seven-segment displays. Are there any tricks involved?
2012-06-02T02:08:34 < zyp> no idea, let's check the documentation again
2012-06-02T02:08:59 < FUZxxl> hehe
2012-06-02T02:09:24 < zyp> reference manual says that the LCD controller can run up to 44x4 or 40x8 matrices of lcd segments
2012-06-02T02:09:44 < FUZxxl> okay.
2012-06-02T02:10:03 < FUZxxl> IIRC the display is using a 40x8 matrix.
2012-06-02T02:10:26 < Laurenceb_> we used cortex-m3 on vertex4 at the place i used to work
2012-06-02T02:10:33 < Laurenceb_> but that certainly wasnt free
2012-06-02T02:10:44 < zyp> FUZxxl, looks like 24x4 in the schematic
2012-06-02T02:11:02 < zyp> I'm seeing COM0-3 and SEG0-23 in the schematic
2012-06-02T02:11:12 < FUZxxl> hm...
2012-06-02T02:11:20 < FUZxxl> okay...
2012-06-02T02:11:53 < FUZxxl> It has 6*16 different parts to light up independently
2012-06-02T02:12:06 < zyp> ah, it says that in the description as well
2012-06-02T02:12:07 < FUZxxl> Yeah. That is 24*4.
2012-06-02T02:12:07 < zyp> LCD (24 segments, 4 commons)
2012-06-02T02:13:05 < FUZxxl> nice.
2012-06-02T02:13:12 < FUZxxl> I'm really tired now.
2012-06-02T02:13:15 < FUZxxl> See you tomorrow!
2012-06-02T02:13:21 < FUZxxl> Thanks for all the help!
2012-06-02T02:13:43 < Thorn> Laurenceb_: m3? is it available for fpgas?
2012-06-02T02:13:51 -!- TitanMKD [Titan@chl26-1-88-183-104-56.fbx.proxad.net] has quit []
2012-06-02T02:16:33 < zyp> ah, table 6 in discovery board datasheet lists the mappings of commons to segments
2012-06-02T02:18:32 -!- peabody124 [~peabody12@128.249.96.21] has quit [Ping timeout: 244 seconds]
2012-06-02T02:18:34 < FUZxxl> oh really?
2012-06-02T02:18:37 < FUZxxl> That's nice.
2012-06-02T02:19:07 < FUZxxl> YOu mean this one: http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/DM00027954.pdf
2012-06-02T02:19:16 < zyp> yes, check page 23
2012-06-02T02:19:24 < FUZxxl> okay
2012-06-02T02:19:28 < FUZxxl> It's loading...
2012-06-02T02:19:55 < zyp> so what you end up with is that each bit in one of the data registers of the lcd controller controls the state of one individual segment of the display
2012-06-02T02:20:19 < FUZxxl> yeah
2012-06-02T02:20:39 < FUZxxl> So if I want to change the displays content, I just write some data into those registers?
2012-06-02T02:20:46 < zyp> exactly
2012-06-02T02:21:26 < FUZxxl> nice.
2012-06-02T02:21:30 < zyp> you'd have to write a function to translate letters into which segments shoult be set if you want to write text
2012-06-02T02:21:38 < FUZxxl> That makes that bloaty API almost redundant.
2012-06-02T02:21:48 < FUZxxl> zyp: That shouldn't be too difficult.
2012-06-02T02:22:01 < zyp> nah, mostly table lookup
2012-06-02T02:22:20 < FUZxxl> I think the best way is to put a short chars[256] into my program..
2012-06-02T02:22:27 < zyp> probably a good exercise to get used to the platform
2012-06-02T02:22:55 < FUZxxl> yeah.
2012-06-02T02:23:03 < FUZxxl> I'm gonna tr that tomorrow.
2012-06-02T02:24:29 < FUZxxl> good night, see you!
2012-06-02T02:35:48 < Laurenceb_> Thorn: not unless you payt
2012-06-02T02:35:59 < Laurenceb_> it was the most disorganised mess ever
2012-06-02T02:37:10 < Laurenceb_> - the setup for using it from arm
2012-06-02T02:37:55 < Laurenceb_> spent ages on phone to arm trying to make it work :P
2012-06-02T02:38:57 < Thorn> so it actually was m3, not m1? why? m1 is (supposed to be) optimized for fpgas
2012-06-02T02:39:13 < Laurenceb_> i dont know, i wasnt that involved in the project even
2012-06-02T02:39:23 < zyp> then it was probably m1
2012-06-02T02:39:29 < Laurenceb_> lol
2012-06-02T02:39:37 < Laurenceb_> maybe - i seem to remeber M3

2012-06-02T04:06:46 < zyp> did he barf on it during soldering?
2012-06-02T04:07:45 < zyp> so, I'm assuming this is the same osd guy? looks like he changed to another type of flux :p
2012-06-02T04:26:26 < dongs> yes
2012-06-02T04:26:53 < dongs> I wonder how many more years its going to take him to finish making a DC/DC converter tha works

2012-06-02T05:55:04 < BrainDamage> you need to add a udev rule
2012-06-02T05:55:09 < BrainDamage> there's the files in the stlink repo
2012-06-02T05:55:19 < BrainDamage> copy them to /etc/udev/rules.d

2012-06-02T07:52:37 < upgrdman> what the difference between a .bin and a .elf?
2012-06-02T08:00:08 < cjbaird> bin: raw binary data, elf: structured format, aka "xml for compiler output"
2012-06-02T08:01:24 < cjbaird> https://en.wikipedia.org/wiki/Executable_and_Linkable_Format
2012-06-02T08:05:09 < dongs> this SiLabs M3 shit looks pretty nice
2012-06-02T08:05:15 < dongs> 300mA drive pins
2012-06-02T08:05:38 < dongs> and looks liek it runs off 5V
2012-06-02T08:05:39 < dongs> hmmmmmmm
2012-06-02T08:05:50 < dongs> very neat
2012-06-02T08:06:21 < cjbaird> Next you be telling us it's available in DIP..
2012-06-02T08:06:36 < dongs> haha
2012-06-02T08:06:41 < dongs> and it has awesome silabs pin remapping
2012-06-02T08:06:52 < dongs> http://www.silabs.com/products/mcu/Pages/crossbar-architecture.aspx#crossbar
2012-06-02T08:07:18 < dongs> that is pretty awesome.
2012-06-02T08:08:17 < R2COM> how much
2012-06-02T08:08:19 < R2COM> $
2012-06-02T08:08:27 < dongs> a bit more expensive than comparable stm32
2012-06-02T08:08:31 < dongs> http://www.digikey.com/product-detail/en/SIM3U157-B-GM/336-2211-ND/2795713
2012-06-02T08:08:33 < dongs> still cheacp
2012-06-02T08:09:14 < R2COM> so what is it good for
2012-06-02T08:09:16 < R2COM> different
2012-06-02T08:09:21 < R2COM> looking at datasheet
2012-06-02T08:09:29 < cjbaird> Actually, I'm surprised that the crossbar thing wasn't already being done.. considering how big a PITA routing was for large chip since the year dot.. (probably patented to all hell)
2012-06-02T08:09:52 < dongs> eh timers are kinda shitty on it
2012-06-02T08:09:59 < dongs> o wait no
2012-06-02T08:10:12 < dongs> 4x16+2x16+6ch motor timer
2012-06-02T08:10:21 < dongs> better than similar package stm32
2012-06-02T08:10:33 < R2COM> crossbar...
2012-06-02T08:10:42 < R2COM> hmm
2012-06-02T08:10:44 < R2COM> well...
2012-06-02T08:10:56 < R2COM> dont see huge need in that
2012-06-02T08:11:25 < upgrdman> cjbaird, so does that mean an ELF has not been linked?
2012-06-02T08:11:49 < upgrdman> or not converted to assembly?
2012-06-02T08:11:58 < dongs> mm 40pin qfn
2012-06-02T08:12:41 < dongs> evenm 92lga isnt so bad
2012-06-02T08:12:47 < dongs> you can route it on 2 layers
2012-06-02T08:22:59 < cjbaird> u: ELF files usually have been linked. It's a resource format for programs-- "this is the starting address, this next chunk is the program executible text, this chunk is the initalized data that goes into RAM, here's the symbol table that a debugger will need, ..."
2012-06-02T08:25:59 < upgrdman> o ok
2012-06-02T08:26:57 < upgrdman> and bin is what gets written to flash? and an elf is used to generate the bin?
2012-06-02T08:33:24 < dongs> BIN THE FLASH
2012-06-02T08:39:44 < cjbaird> pretty-much correct. The "bin" is the .text segment in the elf file.
2012-06-02T09:06:24 < cjbaird> FLASH THE BIN YOU MORONIC FUCKS

2012-06-02T12:44:22 < upgrdman> if a project is written using just the CMSIS stuff, does that mean it can be moved over to other ARM processors with minimal effort? obviously the other proc would need to meet some spec's, like number of timers, gpios, etc, but other than that...

2012-06-02T14:13:39 < dongs> outside US
2012-06-02T14:13:47 < dongs> looks like its cheaper at mouser anyway
2012-06-02T14:13:49 < dongs> fuck digikey
2012-06-02T14:14:19 < TitanMKD> dongs i have not this limitation as my account is language US ;)
2012-06-02T14:14:28 < dongs> TitanMKD: thats irrelevant
2012-06-02T14:14:37 < upgrdman> isnt that chip way overpriced?
2012-06-02T14:14:39 < dongs> you dont get free shipping and they wont ship it anyway
2012-06-02T14:14:45 < dongs> upgrdman: compared to waht
2012-06-02T14:14:53 < upgrdman> 32f4
2012-06-02T14:14:58 < TitanMKD> dongs ha yes that really su*** :(
2012-06-02T14:15:20 < dongs> upgrdman: it has things f4 doesnt.
2012-06-02T14:15:36 < TitanMKD> dongs like what ?
2012-06-02T14:15:40 < upgrdman> o, such as?
2012-06-02T14:15:50 < dongs> analog comparators, pin crossbar
2012-06-02T14:16:07 < dongs> runs off 5V
2012-06-02T14:16:09 < dongs> has 5V output ios
2012-06-02T14:16:14 < dongs> has high current IOs for motor/fet control
2012-06-02T14:16:20 < dongs> touchsense
2012-06-02T14:16:39 < TitanMKD> but also very expensive and slow 80MHz
2012-06-02T14:17:55 < upgrdman> what are touchsense and pin crossbar
2012-06-02T14:18:10 < dongs> http://www.silabs.com/products/mcu/Pages/crossbar-architecture.aspx#crossbar
2012-06-02T14:19:28 < TitanMKD> dongs i prefer f4 ;) for same price you have cortexM4 and FPU and it is 2 time faster
2012-06-02T14:20:09 < TitanMKD> also ADC of F4 is faster
2012-06-02T14:20:33 < zyp> the question is what is more suited for a particular application
2012-06-02T14:20:39 < TitanMKD> anyway for motor stuff maybe this silabs stuff is better but it's not my requirements
2012-06-02T14:21:24 < TitanMKD> zyp Yes i just hate the market fragmentation
2012-06-02T14:21:40 < upgrdman> speaking of motors, how would you drive a typical FET with a 3V MCU like the f4? Vgs is usually >4V
2012-06-02T14:21:56 < zyp> using a fet driver
2012-06-02T14:21:57 < dongs> Laurenceb_: does digikey/whoever have some GPS antennas with u.FL connector at the end?
2012-06-02T14:22:09 < dongs> upgrdman: see, with this silabs shit you can, it has 5V drive IO.
2012-06-02T14:22:26 < dongs> but yeah use a driver.
2012-06-02T14:22:28 < upgrdman> i understand. i come from the arduino work... 5v logic is nice
2012-06-02T14:22:34 < TitanMKD> dongs but 300mA is a bit low for motor ;)
2012-06-02T14:22:48 < TitanMKD> dongs at startup they can reach more than 2Amps
2012-06-02T14:22:48 < dongs> ... its for driving fet gates
2012-06-02T14:22:50 < dongs> not motor directly
2012-06-02T14:22:52 < dongs> what hte fuck dude.
2012-06-02T14:22:57 < TitanMKD> yes ;)
2012-06-02T14:23:12 < TitanMKD> anyway you need additional hardware in both cases
2012-06-02T14:23:13 < dongs> zyp: some guy was demoing me his awesome CNC today and bragging how he bought this $$ spindle driver
2012-06-02T14:23:15 < upgrdman> that mcu can do 300mA per pin? wow
2012-06-02T14:23:26 < dongs> and im like wat kinda motor is that hes like not really sure
2012-06-02T14:23:31 < dongs> i look around its got 3 wires going to it
2012-06-02T14:23:43 < dongs> i was like no wai is that shit just a brushless esc
2012-06-02T14:23:51 < dongs> and it was spinning and making some terrible whine
2012-06-02T14:23:57 < dongs> so i bust out my FFT and its got a peak right at 4khz
2012-06-02T14:24:11 < dongs> not only is it a shitty fucking brushless esc its also got shitty pwm freq ;p
2012-06-02T14:24:16 < zyp> ha
2012-06-02T14:24:46 < upgrdman> dongs, are the good spindle motors sensored brushless?
2012-06-02T14:24:56 < dongs> this wasnt sensored
2012-06-02T14:25:01 < upgrdman> i know
2012-06-02T14:25:06 < upgrdman> dongs, are the good spindle motors sensored brushless?
2012-06-02T14:25:07 < dongs> i dont know what good, I dont do CNC
2012-06-02T14:25:12 < upgrdman> ok
2012-06-02T14:25:21 < zyp> shouldn't be any need to have small motors sensored
2012-06-02T14:25:36 < dongs> yeah startup at low rpm isnt an issue for spindles
2012-06-02T14:26:11 < upgrdman> so then whats a good spindle motor? a stepper?
2012-06-02T14:26:16 < upgrdman> whats wrong with a 3wire blm
2012-06-02T14:26:20 < dongs> nothing.
2012-06-02T14:26:29 < dongs> he spent probably $300+ on a brushless driver that whines at 4khz
2012-06-02T14:26:33 < upgrdman> o
2012-06-02T14:26:41 < dongs> when it coulda been driven by a $10 chinese ESC
2012-06-02T14:26:53 < upgrdman> hobbyking

2012-06-02T14:29:04 < dongs> need another $20 for free shipping
2012-06-02T14:31:06 < upgrdman> why do gps antennas have what looks like a ball of solder in the middle?

2012-06-02T14:36:46 < TitanMKD> dongs i have similar problem of non delivery with Flux Cleaner from Mouser :(
2012-06-02T14:36:58 < TitanMKD> dongs they do not want to sell them outside of USA
2012-06-02T14:37:47 < dongs> i buy that shit locally
2012-06-02T14:37:51 < dongs> spray stuff its really nice
2012-06-02T14:41:30 < zyp> upgrdman, because that's where the connector is soldered
2012-06-02T14:41:50 < zyp> it's produding through a hole in the antenna and soldered on the top
2012-06-02T14:42:08 < zyp> conductor, not connector
2012-06-02T14:45:41 < upgrdman> ok
2012-06-02T14:46:03 < upgrdman> and gps antenna dont like like tradition antennas, why?
2012-06-02T14:46:24 < upgrdman> look like*
2012-06-02T14:51:26 < dongs> zyp what you think about that antenna
2012-06-02T14:52:04 < zyp> no idea, probably ok
2012-06-02T14:52:17 < zyp> upgrdman, different usage
2012-06-02T14:52:18 < dongs> it was most expensive one and 30dB gain
2012-06-02T14:52:57 < zyp> upgrdman, what kind of traditional antennas are you thinking of?
2012-06-02T14:54:13 < upgrdman> radio, wifi, tv...
2012-06-02T14:54:56 < dongs> wat else to get from mouser
2012-06-02T14:55:11 < zyp> upgrdman, because you don't receive radio/wifi/tv signals from satellites that move across the sky all the time
2012-06-02T14:55:27 < BrainDamage> even radios can use weird shape antennas
2012-06-02T14:55:39 < BrainDamage> helical, discone, spiral, etc
2012-06-02T14:55:46 < zyp> gps antennas are optimized to cover the entire sky
2012-06-02T14:55:48 < dongs> GPS antennas are patch
2012-06-02T14:56:00 < dongs> a patch antenna for TV?wifi/wahtever also looks same.
2012-06-02T14:56:06 < zyp> and patch antennas are ideal for that
2012-06-02T14:57:01 < zyp> gps is 1.5 GHz, fm radio is 100 MHz, that's a pretty big difference :p
2012-06-02T14:57:13 < upgrdman> ok
2012-06-02T14:57:40 < BrainDamage> well, you can build a patch antenna for 100MHz too, it'd just be a square of 1.5m per side :p
2012-06-02T14:57:57 < zyp> yep
2012-06-02T14:58:37 < zyp> helical gps antennas are also pretty popular
2012-06-02T14:58:55 < zyp> it's used on a lot of handheld units
2012-06-02T15:00:53 < zyp> directional gps antennas aren't feasible, since the satellites are moving all the time, and you're receiving from several of them at the same time
2012-06-02T15:02:22 < zyp> and quarterwave-stuff like the shit used for wifi is also useless, since it has a donut-shaped pattern along the ground, which won't catch satellites passing directly over you
2012-06-02T15:02:40 < upgrdman> ya

2012-06-03T04:41:59 < upgrdman> in the stm stdperiphlib theres lots of empty assert function definitions and i dont see any calls to them. are they just stubs that can be defined and called manually? in other words, can i safely remote them?
2012-06-03T04:42:14 < upgrdman> remove them*
2012-06-03T04:46:18 < zyp> huh?
2012-06-03T04:46:40 < zyp> can you give an example of what you mean?
2012-06-03T04:49:25 < upgrdman> sure
2012-06-03T04:49:44 < upgrdman> http://pastebin.com/CjLjj4YM
2012-06-03T04:50:49 < zyp> ah, it's an handler that will be called if an assertion is failed
2012-06-03T04:51:10 < upgrdman> but does anything make assertions? i dont see any calls
2012-06-03T04:51:14 < zyp> assert() itself is a macro, which will test for a condition and call the defined handler if it fails
2012-06-03T04:51:39 < zyp> if you don't see any assert() anywhere, then no
2012-06-03T04:51:44 < upgrdman> ok

2012-06-03T05:52:39 < zyp> R2COM, which speed are we looking at?
2012-06-03T06:02:21 < R2COM> well, im thinking of using it with -2 grade spartan6
2012-06-03T06:02:34 < R2COM> i guess, they might do up to 200MHz
2012-06-03T06:02:38 < R2COM> IO
2012-06-03T06:02:50 < R2COM> so, speed of 100MHz or maybe more then
2012-06-03T06:03:32 < R2COM> i guess enough speed for most microcontroller related shit

2012-06-03T06:17:13 < R2COM> just wanted to make sure, i havent yet used stm32 spi, the PB15 pin, stated in pinout description of datasheet as SPI2_MOSI, so from this pin i can give signals OUT to other chips which receive them right?
2012-06-03T06:18:35 < R2COM> i basically want to use my STM32 as a MASTER SPI, the one which writes data to other chips, those chips ONLY receive SPI data, they do not give something back
2012-06-03T06:38:48 < dongs> datasheet is wrong for  tat heh
2012-06-03T06:38:58 < R2COM> is it??
2012-06-03T06:39:00 < R2COM> why?
2012-06-03T06:39:17 < R2COM> im using TQFP64, stm32f405rgt6
2012-06-03T06:41:07 < dongs> MISO: Master In / Slave Out data. This pin can be used to transmit data in slave mode and receive data in master mode.
2012-06-03T06:41:11 < dongs> MOSI: Master Out / Slave In data. This pin can be used to transmit data in master mode and receive data in slave mode.
2012-06-03T06:42:00 < R2COM> well i want my stm32 to be a master, and transmit data to other device
2012-06-03T06:42:49 < dongs> in my project, im receving data on MISO. stm32 is slave,clocked by external device
2012-06-03T06:43:08 < dongs> so thats opposite of wat docs say.
2012-06-03T06:43:24 < dongs> unless im reading it wrong.
2012-06-03T06:43:24 < zyp> really?
2012-06-03T06:43:27 < dongs> yes
2012-06-03T06:43:29 < R2COM> ah darn
2012-06-03T06:43:30 < R2COM> wait
2012-06-03T06:43:33 < R2COM> wrong!
2012-06-03T06:43:33 < zyp> wow
2012-06-03T06:43:53 < dongs> http://bcas.tv/paste/results/lrr4ad32.html
2012-06-03T06:43:59 < R2COM> im looking at reference manual now
2012-06-03T06:44:00 < dongs> i had an error on pcb layout, data input was routed to MOSI
2012-06-03T06:44:05 < zyp> dongs, so MISO is input and MOSI is output regardless of master/slave mode?
2012-06-03T06:44:06 < dongs> and i was getting fuckall
2012-06-03T06:44:22 < dongs> i was getting clock but all zeros in dma buffer
2012-06-03T06:44:25 < R2COM> well..im doing pcb right now
2012-06-03T06:44:36 < dongs> swapped the data pin to MISO and suddenly im getting data OK.
2012-06-03T06:44:46 < dongs> zyp: i dont know, wikipedo also has it swapped
2012-06-03T06:44:53 < zyp> huh?
2012-06-03T06:45:12 < dongs> # SCLK: serial clock (output from master);
2012-06-03T06:45:12 < dongs> # MOSI; SIMO: master output, slave input (output from master);
2012-06-03T06:45:13 < dongs> # MISO; SOMI: master input, slave output (output from slave);
2012-06-03T06:45:29 < zyp> yes, that is correct
2012-06-03T06:45:32 < dongs> right
2012-06-03T06:45:38 < dongs> i mean swapped compared to stm manuala
2012-06-03T06:45:48 < R2COM> so STM manual wrong?!
2012-06-03T06:45:51 < zyp> only for slave mode, or both?
2012-06-03T06:46:07 < dongs> dont know as I've only used slave mode and had this issue
2012-06-03T06:46:35 < zyp> say, what would happen if you hooked two STM32s together, MISO to MISO and MOSI to MOSI, ran one as master and one as slave?
2012-06-03T06:46:45 < zyp> if everything is correct, that should work.
2012-06-03T06:47:20 < R2COM> now im just wondering what configuration would be right for me
2012-06-03T06:47:30 < zyp> I know for sure that master mode is correct on F4, because it works properly with L3GD20 on my board
2012-06-03T06:47:33 < R2COM> i have external digital device, which will have to receive data
2012-06-03T06:47:39 < R2COM> and stm32 will be giving out this data
2012-06-03T06:47:54 < zyp> I have not tried slave mode, but I would be very surprised if that also doesn't work correctly
2012-06-03T06:48:43 < R2COM> zyp, so you use MOSI to OUTPUT the data to another device?
2012-06-03T06:49:05 < zyp> MOSI is used to transfer data from the master to the slave
2012-06-03T06:49:16 < zyp> MISO is used to transfer data from the slave to the master
2012-06-03T06:50:00 < R2COM> ok, if, in my case i want STM32 to generate the clock, and to transfer data to another device, i should use MOSI?   (another device does not transfer anything, it just receives data from STM32)
2012-06-03T06:50:10 < zyp> it's named that way, so you always hook MOSI to MOSI and MISO to MISO
2012-06-03T06:50:26 < zyp> yes
2012-06-03T06:50:38 < R2COM> one sec. let me show diagram
2012-06-03T06:50:38 < zyp> in your case you would hook up clock and MOSI
2012-06-03T06:50:46 < zyp> no need for diagram
2012-06-03T06:52:24 < R2COM> http://picpaste.com/pics/serial_timing-77cOK9wi.1338695516.png
2012-06-03T06:52:36 < R2COM> there CCLK and Master DIN come from STM32
2012-06-03T06:52:57 < R2COM> ignore Master DOUT
2012-06-03T06:53:14 < R2COM> and other signals also connected to stm32, but they are not part of SPI module
2012-06-03T06:53:38 < zyp> wait, is «Master DIN» data from master?
2012-06-03T06:53:51 < R2COM> Master DIN is data coming FROM stm32
2012-06-03T06:53:59 < zyp> I'd assume that «Master DIN» were «data input on master»
2012-06-03T06:55:04 < R2COM> well, this is basically configuration of FPGA in slave serial mode
2012-06-03T06:55:18 < R2COM> FPGA is Slave, it receives serial data, from microprocessor
2012-06-03T06:55:20 < zyp> yeah, I just realized that
2012-06-03T06:55:27 < zyp> hmm
2012-06-03T06:55:29 < R2COM> and i, want to use STM32 to give data to it
2012-06-03T06:55:30 < R2COM> BUT!
2012-06-03T06:55:32 < zyp> which document is that?
2012-06-03T06:55:36 < zyp> let me double check it
2012-06-03T06:55:39 < R2COM> i want to use SPI functionality of STM32 to do that
2012-06-03T06:55:42 < R2COM> one sec
2012-06-03T06:55:42 < zyp> because something doesn't make sense there
2012-06-03T06:56:23 < R2COM> http://www.xilinx.com/support/documentation/user_guides/ug380.pdf
2012-06-03T06:56:31 < R2COM> page 27
2012-06-03T06:58:50 < R2COM> so, there is also SPI type configuration for spartan6, which is using some flash prom in SPI mode... but since im not using those FLASH proms, i do not want to use this method!
2012-06-03T06:59:07 < zyp> I get that
2012-06-03T06:59:21 < R2COM> that is why, i am using just Serial Configuration method, BUT... my STM32 is configuring FPGA in Serial Mode utilizing its own SPI protocol
2012-06-03T06:59:41 < zyp> just forget about that diagram, just look at page 26
2012-06-03T06:59:48 < R2COM> 1 sec
2012-06-03T06:59:59 < R2COM> well
2012-06-03T07:00:02 < zyp> SERIAL_OUT on microprocessor is MOSI
2012-06-03T07:00:06 < R2COM> p.26 is just schematics for all stuff
2012-06-03T07:00:21 < zyp> yes, aren't you asking how to hook it up?
2012-06-03T07:00:31 < R2COM> yes
2012-06-03T07:00:43 < zyp> well, there you have it.
2012-06-03T07:00:46 < R2COM> let me tell you exact pins i used on stm32:
2012-06-03T07:01:04 < zyp> no, I can't be bothered to look up a pin reference
2012-06-03T07:01:20 < R2COM> well i just wanted to tell i used MOSI
2012-06-03T07:01:32 < R2COM> pin which is SPI2_MOSI
2012-06-03T07:01:44 < zyp> let CLOCK be a SPI_CLK pin, SERIAL_OUT be the corresponding SPI_MOSI, and the other three is normal gpios
2012-06-03T07:01:50 < dongs> i think that should work... i guess. since i was using miso to RECEIVE
2012-06-03T07:02:24 < R2COM> zyp: thats what i did. i wasnt going to bother you.
2012-06-03T07:02:26 < R2COM> its just
2012-06-03T07:02:28 < zyp> dongs, in slave mode you would use MOSI to receive
2012-06-03T07:02:33 < R2COM> dongs said docs are fucked up
2012-06-03T07:02:42 < R2COM> and i got suspicious
2012-06-03T07:02:43 < R2COM> thats it
2012-06-03T07:02:53 < dongs> zyp, this is clearly not the case
2012-06-03T07:02:58 < dongs> i have external clock + data
2012-06-03T07:03:07 < dongs> connected to SPI1_CLK and SPI1_MISO
2012-06-03T07:03:08 < zyp> dongs, is this F1?
2012-06-03T07:03:11 < dongs> this is the only way it works
2012-06-03T07:03:12 < dongs> no F4
2012-06-03T07:03:16 < dongs> F405 or so
2012-06-03T07:03:36 < zyp> ok, if this is the case it should be listed in the errata
2012-06-03T07:03:49 < dongs> but arent the docs just fucked?
2012-06-03T07:04:12 < zyp> no SPI peripheral in the errata
2012-06-03T07:05:19 < dongs> soa re you saying that is wrong?
2012-06-03T07:05:37 < dongs> also my spi settings are
2012-06-03T07:05:38 < dongs>     spi.SPI_Direction = SPI_Direction_1Line_Rx;
2012-06-03T07:05:56 < zyp> oh
2012-06-03T07:06:10 < zyp> that may explain it
2012-06-03T07:06:22 < dongs> why>
2012-06-03T07:06:38 < zyp> 1Line sounds like bidirectional mode
2012-06-03T07:06:49 < zyp> i.e. same pin used for both receiving and transmitting
2012-06-03T07:07:27 < zyp> let me check the reference manual
2012-06-03T07:08:34 < zyp> yes
2012-06-03T07:08:36 < zyp> «In this mode SCK is used for the clock and MOSI in master or MISO in slave mode is used for data communication.»
2012-06-03T07:09:59 < zyp> check 27.3.4 in the reference manual for the details
2012-06-03T07:10:58 < zyp> you're likely running BIDIMODE=1, you probably wanted BIDIMODE=0
2012-06-03T07:11:36 < zyp> and in BIDIMODE=0, slave input would be hooked to MOSI like normal
2012-06-03T07:13:37 < zyp> another way to phrase it is that input is remapped to same pin as output in bidirectional mode, i.e. the opposite of what it would normally be in that configuration
2012-06-03T07:14:44 < zyp> that means that in a receive only setup, you can configure it to read from either pin, should you happen to get it wrong on the board :p
2012-06-03T07:16:59 < R2COM> so, docs happen to be right then?
2012-06-03T07:17:07 < zyp> yep
2012-06-03T07:17:45 < zyp> everything is working as intended, dongs just configured it wrong
2012-06-03T07:21:27 < zyp> there is quite a few errors in the documentation, but something as blatantly wrong as confusing MISO and MOSI would surely not go unnoticed, so you should really check your own code before even suggesting such a thing
2012-06-03T07:27:22 < dongs> blah :(
2012-06-03T07:34:56 < R2COM> zyp, you using L3G42?
2012-06-03T07:35:20 < zyp> no, L3GD20
2012-06-03T07:38:55 < R2COM> hm i see L3GD20 is almost same, just allows you choose different sensivities
2012-06-03T07:38:58 < R2COM> and ranges
2012-06-03T07:39:17 < R2COM> sorry
2012-06-03T07:39:23 < R2COM> L3G42 allows to choose
2012-06-03T07:39:27 < R2COM> L3G20 is fixed
2012-06-03T07:40:09 < zyp> L3GD20, not L3G20
2012-06-03T07:40:27 < zyp> and it has selective range.
2012-06-03T07:47:25 < upgrdman> http://pastebin.com/t0W0qeGB    changing HSE_VALUE seems to have no affect. (the LEDs blink at the same speed). any ideas?
2012-06-03T07:49:51 < zyp> you're likely defining a value that's not used anywhere
2012-06-03T07:50:01 < zyp> i.e. you're doing it wrong
2012-06-03T07:50:10 < zyp> are you using chibios? check mcuconf.h
2012-06-03T07:50:45 < upgrdman> no, stm stdperiphlib
2012-06-03T07:51:05 < upgrdman> how do you like chibios?
2012-06-03T07:52:13 < zyp> haven't used it for a year, seems okay though
2012-06-03T07:53:15 < R2COM> is it like RtOS?
2012-06-03T07:53:22 < R2COM> real time operating system?
2012-06-03T07:53:33 < zyp> chibios is an rtos, yes
2012-06-03T07:53:51 < R2COM> i dont see many usage for RTOS on most embedded systems
2012-06-03T07:53:52 < R2COM> really
2012-06-03T07:54:04 < R2COM> unless system will have a user running/doing different stuff on it
2012-06-03T07:54:15 < zyp> ha
2012-06-03T07:54:25 < R2COM> why to put all that shit on a system when you can get away writing just long enough but predefined C program
2012-06-03T07:54:53 < zyp> you've clearly misunderstood the point of an rtos
2012-06-03T07:55:56 < R2COM> i understand it, mostly to handle real time issues like interrupts etc
2012-06-03T07:56:00 < R2COM> and writing data
2012-06-03T07:56:04 < R2COM> while doing something
2012-06-03T07:56:16 < R2COM> what i say, for most applications that can just be done with a program
2012-06-03T07:56:30 < upgrdman> do people still code in assembly for mcu's?
2012-06-03T07:56:57 < zyp> R2COM, what is the difference between a program and using an rtos then?
2012-06-03T07:57:11 < zyp> upgrdman, as for me; only inline
2012-06-03T07:58:05 < R2COM> zyp: well, writing specialized program which handles all real time related things, and still does the job is more efficient and wastefull than putting RTOs on a chip, or am i wrong?
2012-06-03T07:58:36 < zyp> upgrdman, some times you need specific instructions to achieve something, like a context switch, other times the compiler does a bad job of optimizing a very hot code path
2012-06-03T07:58:57 < upgrdman> hot? does that mean time critical?
2012-06-03T07:59:15 < zyp> hot as in «runs a lot»
2012-06-03T07:59:20 < upgrdman> o
2012-06-03T07:59:58 < zyp> inner loops and so on
2012-06-03T08:00:23 < R2COM> *and less wastefull
2012-06-03T08:00:57 < zyp> R2COM, I believe you have the wrong idea of what an rtos is
2012-06-03T08:01:42 < zyp> the os-part of an rtos is mainly multithreading
2012-06-03T08:01:58 < zyp> i.e. the capability to have several threads running at the same time
2012-06-03T08:02:16 < R2COM> ok
2012-06-03T08:02:36 < zyp> and the rt-part is a scheduler that is capable of running those threads subject to realtime constraints
2012-06-03T08:02:58 < R2COM> but...it runs those threads technically *NOT* at the same time
2012-06-03T08:03:00 < R2COM> right?
2012-06-03T08:03:09 < R2COM> in its internals
2012-06-03T08:03:12 < R2COM> it switches
2012-06-03T08:03:25 < zyp> of course they don't run at the same time, you only have one cpu
2012-06-03T08:03:31 < R2COM> yes
2012-06-03T08:03:56 < R2COM> someone pointed me out recently on chips called xmos, they have hardware multithreading supported i guess
2012-06-03T08:04:02 < zyp> the scheduler is controlling which threads to run
2012-06-03T08:04:39 < R2COM> zyp: ok i know that, now what i say is, that there is no need to do that so often in most embedded systems
2012-06-03T08:04:48 < zyp> and the realtime constraints is like «this thread must respond within 1 ms of that happening»
2012-06-03T08:05:01 < R2COM> ok
2012-06-03T08:05:31 < zyp> and in real world control systems, the ability to respond to input within a given deadline can be very critical
2012-06-03T08:06:04 < R2COM> ok, now, why to have an OS do it for you and not just write your code?
2012-06-03T08:07:37 < zyp> because you're likely to have several tasks, some of high priority, some of low priority
2012-06-03T08:07:55 < R2COM> ok
2012-06-03T08:08:30 < zyp> stuff like user interfaces are not very real time critical, so that can run in low priority threads
2012-06-03T08:09:36 < zyp> and it still sounds like you believe that an rtos is some huge resource-eating stuff

2012-06-03T08:11:41 < dongs> xmos is deader than *bsd
2012-06-03T08:11:51 < R2COM> hmm why is it deader?
2012-06-03T08:12:01 < R2COM> whats the problem you see with it?
2012-06-03T08:13:21 < zyp> what I've heard about xmos is «hey, we've got lots of processing power, let's just waste it on bitbanging everything!»
2012-06-03T08:14:17 < R2COM> but processing power is to be used internally to "process" its not meant for bit-banging, i mean if used properly then whats the problem
2012-06-03T08:14:37 < R2COM> the reason im so curious is, they have cheap prices
2012-06-03T08:15:01 < zyp> but that's everything I'm going to say about it, I don't have any experience with xmos, so I'm not going to make any more uninformed comments

2012-06-03T08:18:56 < zyp> hmm, «400 MIPS»
2012-06-03T08:19:08 < zyp> F4 is rated to 210 MIPS

2012-06-03T08:27:21 < zyp> ah, right, here's the catch
2012-06-03T08:28:07 < zyp> you have to have at least four active threads per core to keep the core fully occupied
2012-06-03T08:28:32 < zyp> each thread get at most 100 MIPS
2012-06-03T08:29:22 < zyp> so for the 1600 MIPS variant, you need to be able to split the workload across at least 16 threads
2012-06-03T08:30:53 < zyp> this makes it suited for highly parallelizable tasks, think similar to GPU/GPGPU workloads
2012-06-03T08:33:31 < zyp> and very useless for algorithms where each calculation is dependant on the output of the previous and similar tasks
2012-06-03T08:35:15 < dongs> < zyp> what I've heard about xmos is «hey, we've got lots of processing power, let's just waste it on bitbanging everything!»
2012-06-03T08:35:19 < dongs> zyp: you must be thinking propeller
2012-06-03T08:35:23 < dongs> but im sure xmos is nodifferent
2012-06-03T08:35:43 < zyp> no, this is xmos I'm talking about, I looked it up
2012-06-03T08:36:39 < zyp> hmm, propeller looks pretty different
2012-06-03T08:38:04 < cjbaird> "let's just waste it on bitbanging everything" ... the Connection Machine guys said the same thing too.. -_-
2012-06-03T08:38:21 < zyp> propeller has 8 actual cores running independently, xmos has a four-level pipeline allowing four threads to be running on the same core in different stages at the same time
2012-06-03T08:40:06 < zyp> looks like propeller does 20 MIPS per core, 160 MIPS in total
2012-06-03T08:40:44 < zyp> that's pretty shitty, looks unfair to compare xmos to that :p
2012-06-03T08:42:52 < zyp> hmm, kind of want an xmos board to play with, guess I'll pick one up if I come across it
2012-06-03T08:51:16 < jpa-> it also depends a lot on how costly it is to synchronize the threads.. e.g. if it is sensible to parallelize a 16-item dotproduct or not
2012-06-03T08:52:54 < zyp> yep

2012-06-03T10:33:50 < jpa-> hmm, apparently full-speed usb works just fine on HSI on STM32L151.. even though it's not officially within the clock accuracy requirements
2012-06-03T10:57:57 < gsmcmullin> jpa-: It does for me on the f103 too.
2012-06-03T11:00:39 < pelrun__> who knows if it'll work on all usb ports or with random hubs though
2012-06-03T11:00:42 < pelrun__> still, cool to know
2012-06-03T11:02:20 < gsmcmullin> pelrun__: Yes, it's out of spec, so don't do it if you need it to be reliable.

2012-06-03T12:05:41 < jpa-> why are you upgrading it?
2012-06-03T12:11:58 < pelrun__> stlink v1 is poo
2012-06-03T12:12:13 < pelrun__> also it doesn't give me swv/swo/whatever debug trace facility

2012-06-03T13:03:46 < SuicideFunky> hello folks
2012-06-03T13:05:27 < SuicideFunky> having problmens with DMA in mem2mem mode. When i initiate the xfer (by setting count register to > 0 and enable the channel), it seems the interrupt on complete is always called
2012-06-03T13:06:05 < SuicideFunky> although the docs mention the dma channel is disabled after the DMA_CNDTR reaches zero
2012-06-03T13:06:18 < SuicideFunky> anyone have a clue?
2012-06-03T13:06:42 < jpa-> what do you mean "always called"?
2012-06-03T13:06:48 < jpa-> do you clear the interrupt flag?
2012-06-03T13:07:44 < SuicideFunky> no i do not, that may be it, then i missed something in the docs
2012-06-03T13:07:52 < SuicideFunky> the interrupt vector is called non-stop
2012-06-03T13:08:09 < SuicideFunky> i can see that when i toggle the blue LED in the vector
2012-06-03T13:08:35 < SuicideFunky> then the led's brightness decreases
2012-06-03T13:08:56 < jpa-> yeah, you need to clear the interrupt flag
2012-06-03T13:08:57 < jpa-> DMA1->IFCR = DMA_IFCR_CTCIF4;
2012-06-03T13:08:59 < jpa-> or similar

2012-06-03T15:32:46 < dongs> used npn and a led...
2012-06-03T15:32:53 < dongs> and they're on, off when data
2012-06-03T15:32:56 < dongs> wanted reverse.

2012-06-03T15:41:05 < dongs> yeah
2012-06-03T15:44:37 < Tectu_> so you just wired them up the wrong way
2012-06-03T15:44:44 < Tectu_> please give me the schematics
2012-06-03T15:45:27 < dongs> http://i.imgur.com/hnwlN.png im pretty sure i fucked something up. but I did copy this circuit from somewehre i just cant remember where
2012-06-03T15:46:29 < Tectu_> yes, this is wrong
2012-06-03T15:46:39 < Tectu_> when Rx geths high, the LED lights up
2012-06-03T15:46:44 < Tectu_> when it gets low, the LED dosen't light up
2012-06-03T15:46:48 < dongs> yeah.
2012-06-03T15:46:52 < Tectu_> and bceause UART is "active low" that dosen't work
2012-06-03T15:47:00 < dongs> right.
2012-06-03T15:47:15 < Tectu_> and you don't know how to fix that or what's your "question"?
2012-06-03T15:47:23 < dongs> correct.
2012-06-03T15:47:41 < Tectu_> ok
2012-06-03T15:47:46 < Tectu_> there are (of course) many ways
2012-06-03T15:47:47 < dongs> will just swapping transistors for a pnp work?
2012-06-03T15:48:23 < Tectu_> dongs, yes, but then you need to place the LEDs in the seconds segment. so this way:     vcc --- transistor --- LED --- resistor ---- GND
2012-06-03T15:48:54 < Tectu_> but well, what you also can do:     VCC --- LED --- resistor --- RxD/TxD
2012-06-03T15:48:57 < Tectu_> that works fine :)
2012-06-03T15:49:07 < dongs> heh
2012-06-03T15:49:11 < dongs> ya but ghetto
2012-06-03T15:49:31 < Tectu_> http://www.scienceprog.com/wp-content/uploads/2006i/RS232_adapter1/RS232_adapter.PNG
2012-06-03T15:49:34 < Tectu_> no
2012-06-03T15:49:36 < Tectu_> not really
2012-06-03T15:49:42 < dongs> yes really
2012-06-03T15:49:44 < Tectu_> that is done in many many industrial applicatoins too
2012-06-03T15:50:15 < pelrun_> it's no problem if you don't mind making your uart pin sink current
2012-06-03T15:50:32 < pelrun_> couple of mA wouldn't hurt
2012-06-03T15:50:35 < dongs> ^ eaxctly
2012-06-03T15:50:46 < dongs> its ok for one off but not ok for production
2012-06-03T15:50:52 < dongs> or for debuggingetc.
2012-06-03T15:51:25 < Tectu_> dongs, http://www.mikrocontroller.net/attachment/33500/pnp.jpg
2012-06-03T15:51:34 < Tectu_> (don't forget resistor)
2012-06-03T15:51:43 < dongs> so jsut swapping fora pnp might work?
2012-06-03T15:51:46 < dongs> lemme try that..
2012-06-03T15:52:44 < pelrun_> oh heh, that would work pretty well
2012-06-03T15:53:04 < pelrun_> fixes the problem with having to pull the base above the collector too
2012-06-03T15:53:49 < pelrun_> although they need to be slapped for forgetting the resistor :)
2012-06-03T15:54:23 < Tectu_> pelrun_, i was too tired of drawing it myself, so i just searched a matching google picture ;)
2012-06-03T15:54:32 < pelrun_> heh

2012-06-03T16:40:59 < pelrun_> dongs: probably to stop that input floating
2012-06-03T16:41:24 < pelrun_> since the output would be at rs232 levels
2012-06-03T16:41:37 < Tectu_> dongs, what exactly do you mean?
2012-06-03T16:41:44 < pelrun_> the other way isn't so critical, since the output is only ttl
2012-06-03T16:41:55 < dongs> o rite. so just to shut it up
2012-06-03T16:42:58 < pelrun_> yeah, they could just as easily set it to 0 or 5v, but since the other signal is right there they're just being lazy and tying them together

2012-06-03T16:59:44 < dongs> and: you might needs disable/enable_irq around it

2012-06-03T18:50:04 < Laurenceb_> as good as the 9150
2012-06-03T18:50:28 < Laurenceb_> lower full scale
2012-06-03T18:50:44 < dongs> oh snap
2012-06-03T18:50:53 < dongs> but 9150 = i2fuckingc
2012-06-03T18:51:04 < Laurenceb_> Zero-rate output variation over temperature: ±0.14°/sec/°C
2012-06-03T18:51:08 < Laurenceb_> thats improved
2012-06-03T18:51:14 < Laurenceb_> still a bit lame

2012-06-03T18:54:06 < lukky513> Laurenceb_: I need a way to bridge USB to USART, does it provide it?
2012-06-03T18:54:25 < Laurenceb_> erm i could
2012-06-03T18:54:34 < Laurenceb_> but thats a poor use of an stm

2012-06-03T18:55:10 < lukky513> can I set it to work in reasonable time?

2012-06-04T00:05:54 < lukky513> soooo... it doesn't work
2012-06-04T00:06:06 < lukky513> I can't get virtual com example running
2012-06-04T00:06:10 < lukky513> it doesn't pass enumeration
2012-06-04T00:06:50 < Laurenceb_> what code are you using?
2012-06-04T00:08:49 < Tectu> anyone ever calibrated touchpad?
2012-06-04T00:08:59 < lukky513> example from st, version for 3210c-eval
2012-06-04T00:09:13 < lukky513> I don't have this eval though, but it's almost compatible
2012-06-04T00:09:39 < lukky513> mcu is the same and pins are connected likewise... except for resistors
2012-06-04T00:10:03 < lukky513> I'm trying to get it working as it is, though - I can't add anything to this board, technically
2012-06-04T00:11:16 < lukky513> it seems like these externals should be the source of problem... but I can't help it in any way
2012-06-04T00:11:44 < lukky513> I thought about data pullup, but it's not present in 3210
2012-06-04T00:12:04 < lukky513> so I guess it's realised through OTG internal hw, somehow
2012-06-04T00:16:33 < gsmcmullin> lukky513: Remove your pull-up, it's internal.
2012-06-04T00:18:17 < lukky513> I don't have any; infact, I couldn't even put it there
2012-06-04T00:19:01 < gsmcmullin> I don't know ST's code at all.  Other thing to check is the VBUS detect.
2012-06-04T00:19:31 < lukky513> you mean?
2012-06-04T00:20:18 < zyp> lukky513, what is the problem?
2012-06-04T00:21:15 < lukky513> zyp: enumeration failed/device not working at all
2012-06-04T00:21:33 < lukky513> I'm using slightly modified version of stm32 example
2012-06-04T00:21:43 < Laurenceb_> sure the pins are connected?
2012-06-04T00:21:45 < Laurenceb_> :P
2012-06-04T00:21:59 < lukky513> Laurenceb_: yes... I'm using evaluation board
2012-06-04T00:22:04 < zyp> ah, you're using F107
2012-06-04T00:22:21 < zyp> that should be same usb peripheral as F4
2012-06-04T00:22:28 < zyp> I do have some experience with it
2012-06-04T00:25:00 < zyp> but you'd have to be more specific
2012-06-04T00:25:09 < lukky513> okay, so first - schematics
2012-06-04T00:25:30 < zyp> no external pullups or anything is required
2012-06-04T00:25:31 < lukky513> I'm using code made for stm3210c-eval: please refer to http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/USER_MANUAL/CD00212441.pdf - page34
2012-06-04T00:26:03 < lukky513> and my board is some lousy http://www.kamami.pl/dl/zl29arm.pdf - page 5
2012-06-04T00:26:31 < lukky513> at first sight most important difference is (un)presence of 22R on D+/- lines
2012-06-04T00:26:56 < lukky513> I'm not very experienced... but I wouldn't say it matters
2012-06-04T00:27:18 < lukky513> sorry for Polish, I can translate if needed :)
2012-06-04T00:27:26 < zyp> they should be there, but it would likely work without
2012-06-04T00:27:37 < zyp> no, it's ok, I'm just looking at schematics
2012-06-04T00:27:59 < lukky513> jumpers are ok
2012-06-04T00:28:36 < lukky513> there'd be no notice from PC if they weren't, anyway
2012-06-04T00:28:53 < zyp> ah, so you get some response?

2012-06-04T00:30:42 < lukky513> it doesn't matter, it's device, that's one
2012-06-04T00:30:50 < zyp> you might have to force it into device mode then
2012-06-04T00:30:53 < lukky513> two: I don't have usb mini connector on my board :)
2012-06-04T00:31:20 < lukky513> hm, you say, but how?
2012-06-04T00:31:24 < zyp> on my board, I've wired it as device-only, omitted ID line, so I'm forcing it into device-only mode
2012-06-04T00:32:02 < lukky513> I guess it's so here by design
2012-06-04T00:32:13 < zyp> you set FDMOD bit in GUSBCFG register
2012-06-04T00:32:26 < zyp> I don't know how to do it through ST's code, I've not used that
2012-06-04T00:33:15 < lukky513> right after clock setting? hm
2012-06-04T00:33:28 < lukky513> I'd have to browse whole USB init code

2012-06-04T12:33:53 < pelrun_> talk to me dammit
2012-06-04T12:35:34 < pelrun_> Tectu, aren't normal interrupts and the rtos mostly independent?
2012-06-04T12:38:21 < Thorn> chibios has its own drivers for everything

2012-06-04T13:02:32 < zyp> not that particular movie, but that copter
2012-06-04T13:04:21 < karlp> don't know, I'm not an RC person.
2012-06-04T13:04:29 < karlp> just got sent to me.
2012-06-04T13:17:44 < Tectu> Thorn, experience with EXT in chibi?
2012-06-04T13:18:51 < Thorn> none at all
2012-06-04T13:35:18 < Tectu> 	Enables an EXT channel.
2012-06-04T13:35:29 < Tectu> STM32 -> i can have my external interrupt everywhere, right?
2012-06-04T13:35:39 < Tectu> its not that only a few pins are external interrupt able, right?
2012-06-04T13:35:51 < Tectu> so i can say, wooh, PortC 6 is external interrupt now?
2012-06-04T13:36:29 < cjbaird> Heaps of uxtb instructions everywhere making the place look ugly..
2012-06-04T13:59:22 < dongs> new ida 6.3 is out

2012-06-04T13:59:50 < dongs> so everyoen and their mother is messaging me that link
2012-06-04T13:59:59 < dongs> the original was posted at least a month mybe more ago
2012-06-04T14:00:14 < dongs> fucking useless internet
2012-06-04T14:02:55 < Tectu> did you sleep well, dongs?
2012-06-04T14:03:03 < dongs> wat
2012-06-04T14:05:36 < dongs> Tectu: each port is shared
2012-06-04T14:05:48 < dongs> i.e. PB6, PC6, PA6 will trigger same EXTI line
2012-06-04T14:05:53 < Tectu> dongs, so i can only have 16 external interrupts?
2012-06-04T14:05:54 < Tectu> ah!
2012-06-04T14:05:59 < dongs> also only first few lines are individual
2012-06-04T14:06:05 < dongs> i.e. exti0, exti1 etc
2012-06-04T14:06:08 < Tectu> so no ext interrupt for PA8 and PC8 ?
2012-06-04T14:06:08 < dongs> then they become shared
2012-06-04T14:06:10 < dongs> exti10-15
2012-06-04T14:06:17 < Tectu> so we get 16*16 interrupts?
2012-06-04T14:06:35 < dongs> you cant distinguish which port did exti i dont think
2012-06-04T14:06:39 < dongs> you attach port -> line
2012-06-04T14:06:50 < dongs> so you can do either pa8 or pc8, but not both, as far as I know.
2012-06-04T14:06:56 < Tectu> ok
2012-06-04T14:07:02 < dongs> and there are 16 lines.
2012-06-04T14:07:06 < dongs> + a couple system ones
2012-06-04T14:07:44 < dongs> Figure 27 in f4 reference manual
2012-06-04T14:07:55 < dongs> looks like tehre's about 8 system lines
2012-06-04T14:08:02 < dongs> rtc alarm, usb wakeup, shit like that
2012-06-04T14:08:12 < dongs> and the 0..15 are for gpio
2012-06-04T14:14:21 < upgrdman> any idea why "uint8_t inputStartingTime[8] = {0};" works, but "uint32_t inputStartingTime[8] = {0};" (32bit int) fails with "undefined reference to `memset'"??
2012-06-04T14:14:33 < dongs> yes
2012-06-04T14:14:44 < dongs> = { 0, } gets compiled into something like
2012-06-04T14:14:56 < dongs> blah[size]; memset(blah, 0, sizeof(blah));
2012-06-04T14:15:06 < dongs> small sized stuff is initialized inline
2012-06-04T14:15:14 < dongs> i.e. just blah[0] = 0; blah[1] = 0;
2012-06-04T14:15:17 < Tectu> dongs, how to fix?
2012-06-04T14:15:23 < zyp> is this stack or global?
2012-06-04T14:15:28 < upgrdman> oh. is that specific to mcu's? i dont recall this problem with normal software dev
2012-06-04T14:15:30 < dongs> sounds liek stack
2012-06-04T14:15:34 < zyp> yeah
2012-06-04T14:15:38 < zyp> because it won
2012-06-04T14:15:43 < zyp> 't use memset for global
2012-06-04T14:15:45 < Thorn> if it were global you wouldn't need memset
2012-06-04T14:16:02 < Thorn> also, doesn't gcc use builtin memset at some -O level?
2012-06-04T14:16:36 < upgrdman> ok
2012-06-04T14:17:03 < upgrdman> im used to globals being "bad" unless they really need to be global... are the common when doing mcu stuff?
2012-06-04T14:17:04 < Thorn> http://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html
2012-06-04T14:17:36 < Thorn> The ISO C90 functions ..., memset, ... are all recognized as built-in functions unless -fno-builtin is specified (or -fno-builtin-function is specified for an individual function).
2012-06-04T14:17:37 < dongs> well you can just link to whatever lib that provides memset...
2012-06-04T14:18:12 < zyp> upgrdman, that depends
2012-06-04T14:18:24 < zyp> globals are good for a lot of shit
2012-06-04T14:19:49 < zyp> globals being bad has to do with reentrancy
2012-06-04T14:20:02 < upgrdman> ?
2012-06-04T14:20:13 < Thorn> just make them static for internal linkage whenver possible
2012-06-04T14:20:14 < dongs> zyp, what was that command line to turn hex into bin

2012-06-04T14:20:26 < dongs> i think od? or someshit
2012-06-04T14:20:29 < dongs> you pasted me before.
2012-06-04T14:20:41 < zyp> huh?
2012-06-04T14:20:41 < dongs> or one of lunix hax0-rs did
2012-06-04T14:20:53 < dongs> i have a .txt of hex
2012-06-04T14:20:55 < zyp> is this ihex or just some plain hex shit?
2012-06-04T14:21:00 < dongs> plain text
2012-06-04T14:21:05 < dongs> not fixed length either

2012-06-04T14:21:17 < dongs> i.e. shit like this
2012-06-04T14:21:21 < Thorn> in ihex lines start with :
2012-06-04T14:21:25 < dongs> right.
2012-06-04T14:21:27 < dongs> its not ihex.
2012-06-04T14:21:36 < zyp> I'd probably use python
2012-06-04T14:21:45 < dongs> ok then it probably wasnt you
2012-06-04T14:22:09 < dongs> found it
2012-06-04T14:22:11 < zyp> open('outfile', 'w').write(''.join(line.decode('hex') for line in open('infile')))

2012-06-04T15:05:57 < upgrdman> if i want to check bit "n" to see if its equal to 0, this should work, right? number | (1 << n) != number ... (that would be true if the bit is zero)
2012-06-04T15:12:05 < Thorn> the caninocal way is !(number & (1<<n))
2012-06-04T15:12:22 < Thorn> *canonical
2012-06-04T15:12:26 < cjbaird> clear the bit (bic.w Rn ...), and test if the value changes?

2012-06-04T22:24:36 < Tectu> stm32 big or little endian? o0
2012-06-04T22:24:37 < Tectu> confused
2012-06-04T22:26:31 < karlp> hint, you probably don't care.
2012-06-04T22:26:59 < karlp> or, you should write your code such that it doesn't care.
2012-06-04T22:27:24 < karlp> (don't use pointer tricks to convert things)
2012-06-04T22:33:12  * zyp converts karlp with pointer tricks
2012-06-04T22:34:09 < Tectu> aw :(
2012-06-04T22:34:18 < zyp> Tectu, little endian
2012-06-04T22:34:23 <+Steffanx> A little or big endian system zyp ?
2012-06-04T22:34:34 < zyp> Steffanx, middle endian
2012-06-04T22:34:44 <+Steffanx> Ah,
2012-06-04T22:36:34 <+Steffanx> Time for an endianless system :)
2012-06-04T22:36:38 <+Steffanx> Pure magic
2012-06-04T22:37:08 < zyp> easy, just restrict operation to one word size only
2012-06-04T22:37:45 <+Steffanx> And when you need two you're screwed
2012-06-04T22:37:59 < zyp> I don't know if you have seen the DCPU-16 stuff the kids are playing with nowadays, it's endianless
2012-06-04T22:38:11 < zyp> or the version of the spec I last read were, at least
2012-06-04T22:38:54 <+Steffanx> And who defines who you store "123456789" ?
2012-06-04T22:39:15 < zyp> what do you mean?
2012-06-04T22:39:22 <+Steffanx> *who = how
2012-06-04T22:39:35 < zyp> in what sense?
2012-06-04T22:40:29 < zyp> memory is two-dimensional, bits and bytes are orthogonal
2012-06-04T22:41:00 <+Steffanx> So ..
2012-06-04T22:41:31 < zyp> so?
2012-06-04T22:41:41 < zyp> so bit order doesn't matter
2012-06-04T22:42:26 <+Steffanx> but byte order does, isn't that where the endianness systems are 'designed'  for?
2012-06-04T22:43:01 < zyp> endianness refers to the byte order when you have to split a large word into several bytes
2012-06-04T22:44:01 <+Steffanx> My endianless system was more like a randomainess system :P
2012-06-04T22:44:32 <+Steffanx> *randomianess
2012-06-04T22:44:37 < zyp> the address only refers to whole bytes, not the individual bits inside an byte, so it has nothing to do with endianness
2012-06-04T22:45:01 < zyp> but you can say that you get a similar problem when you are serializing a byte
2012-06-04T22:45:20 < zyp> then you split an 8-bit word into eight 1-bit words
2012-06-04T22:45:32 < zyp> that you can send either MSB or LSB first
2012-06-04T22:51:45 <+Steffanx> Your interpreter thought of "123456789" being a string, didn't it zyp ?
2012-06-04T22:52:17 < zyp> no, I thought of it as a number
2012-06-04T22:52:43 <+Steffanx> okok
2012-06-04T22:52:54 <+Steffanx> I guess you read the right specs
2012-06-04T23:11:05 < jpa-> hmm.. is it crazy to think that there is misalignment error between the accelerometer and magnetometer axes on my LSM303?
2012-06-04T23:11:52 < zyp> that sounds pretty crazy, yes
2012-06-04T23:11:53 < zyp> :p
2012-06-04T23:12:14 < zyp> why do you suspect that?
2012-06-04T23:13:32 < jpa-> i put the device on horizontal table and rotated it.. accelerometer data indicates that it was perfectly level (within 1°), but magnetometer data rotates around an axis that is 5° from vertical direction
2012-06-04T23:17:51 < jpa-> have to check more carefully tomorrow
2012-06-04T23:24:42 < zyp> that sounds pretty normal
2012-06-04T23:26:12 < zyp> remember that magnetometers are affected by other shit around them and have to be calibrated
2012-06-04T23:36:48 < Tectu> should this tell me something?
2012-06-04T23:36:48 < Tectu> Note: automatically using hardware breakpoints for read-only addresses.
2012-06-04T23:36:57 < Tectu> i do get it sometimes and sometimes i don't
2012-06-04T23:39:08 < Laurenceb_> jpa-: did you calibrate both sensors?
2012-06-04T23:39:21 < Laurenceb_> my lsm303 sensors both have fairly large gain and bias offsets
2012-06-04T23:39:28 < Laurenceb_> particularly the magno
2012-06-04T23:43:59 < zyp> Laurenceb_, duh, all magnos do, it's called soft and hard iron effects
2012-06-04T23:44:17 < Laurenceb_> yeah
2012-06-04T23:44:27 < Laurenceb_> thats my point
2012-06-04T23:44:44 < zyp> the rest of your board that the magno is mounted on affects the measurements, so you have to calibrate it after it's mounted on the board
2012-06-04T23:46:04 < Laurenceb_> also the soldering effects it
2012-06-04T23:46:21 < zyp> http://bin.jvnv.net/f/unBCL.png <- here's from some shit I calibrated last year
2012-06-04T23:46:47 < zyp> blue is actual samples, red is the sphere that the samples should lie on
2012-06-04T23:47:24 < Laurenceb_> looks like my results
2012-06-04T23:48:02 < zyp> yeah, I guess z is most affected because of the ground plane, or something
2012-06-04T23:49:08 < Laurenceb_> seems unlikely
2012-06-04T23:49:13 < Laurenceb_> probably just chance

2012-06-05T08:06:54 < szczys> Hi all
2012-06-05T08:07:17 < szczys> I've got a question about the firmware package that ST has published for their new STM32F0-Discovery board
2012-06-05T08:07:25 < szczys> is this the right place to ask?
2012-06-05T08:08:23 < dongs> sure
2012-06-05T08:08:30 < szczys> Great!
2012-06-05T08:08:48 < szczys> I downloaded the package, but I don't see a source file that I think should have been included with the CMSIS
2012-06-05T08:08:56 < szczys> There is a core_cm0.h file
2012-06-05T08:09:01 < szczys> but there is no core_cm0.c file
2012-06-05T08:09:14 < szczys> does this sound like a problem?
2012-06-05T08:09:47 < dongs> core_cm?.c/h should be in same dir
2012-06-05T08:09:53 < dongs> under CMSIS\CM0\CoreSupport or so.
2012-06-05T08:09:58 < dongs> did  you download stdperiphlib?
2012-06-05T08:10:04 < dongs> or just F0discover  specific package
2012-06-05T08:10:23 < szczys> the F0 specific package
2012-06-05T08:10:45 < szczys> available here: http://bit.ly/JQZ1bW
2012-06-05T08:10:50 < szczys> click the support tab
2012-06-05T08:10:53 < szczys> package is at the bottom
2012-06-05T08:13:31 < szczys> I also downloaded the stm32f0_stdperiph_lib.zip file
2012-06-05T08:13:42 < szczys> and I don't see the core_cm0.c file there either
2012-06-05T08:13:53 < szczys> Now I've been able to compile the peripherals library
2012-06-05T08:14:09 < szczys> but I haven't tested it yet... I'm just trying to get up and running
2012-06-05T08:14:15 < szczys> for the first time
2012-06-05T08:14:28 < szczys> (I'm in a bit over my head but I think I'll get it.)
2012-06-05T08:15:49 < dongs> hm
2012-06-05T08:16:09 < dongs> so wahts inside CMSIS\CM0\CoreSupport?
2012-06-05T08:16:10 < dongs> just .h file?
2012-06-05T08:16:38 < cjbaird> Meeeeh... Element14 sent an order via super-elite-expensive-neutrino-express shipping ($13 for a 100g package..), when I'd lodged it as a trade-counter pickup. :/ .. I bothered them just then to get my monies back.
2012-06-05T08:17:08 < szczys> \Libraries\CMSIS has three directories:
2012-06-05T08:17:11 < szczys> ST

2012-06-05T08:17:18 < szczys> and Documentation
2012-06-05T08:17:31 < dongs> weird maybe they moived shit around
2012-06-05T08:18:00 < szczys> well... I don't find any src files in the CMSIS folder
2012-06-05T08:18:06 < dongs> o wait
2012-06-05T08:18:11 < szczys> all of the C files look to be part of the peripherals
2012-06-05T08:18:11 < dongs> F4 cmsis doesnt have .c either
2012-06-05T08:18:14 < dongs> youre probably ok.
2012-06-05T08:18:17 < szczys> oh... okay
2012-06-05T08:18:21 < szczys> thanks!
2012-06-05T08:18:34 < dongs> core_cm0.h looks much bigger than the one included in M3 CMSIS
2012-06-05T08:18:40 < dongs> so they probably jut moved all teh shit from .c into h
2012-06-05T08:18:45 < dongs> it was mostly asm macros for shit anyway
2012-06-05T08:18:47 < szczys> right, I see
2012-06-05T08:19:03 < szczys> thanks for taking the time to check into it, I do appreciate it!
2012-06-05T08:19:32 < szczys> I believe I found a bug in one of the peripheral C files
2012-06-05T08:19:56 < dongs> unlikely, but..
2012-06-05T08:20:13 < szczys> well, I'm using arm-none-eabi-gcc
2012-06-05T08:20:28 < szczys> and got a compiler error when it got to the dac source file
2012-06-05T08:20:41 < szczys> undefined function, needed to include another header file
2012-06-05T08:21:11 < dongs> i usually only build files from stdperiphlib for the peripherals im gonna use..
2012-06-05T08:21:34 < szczys> I'm following an example package built for one of the other Discovery boards
2012-06-05T08:22:12 < szczys> https://github.com/texane/stlink/tree/master/example/libs_stm/build
2012-06-05T08:22:30 < szczys> the make files in that directory build one big .a file out of the peripherals
2012-06-05T08:26:34 < szczys> anyway... off to bed. Thanks for the advice!

2012-06-05T13:36:34 < upgrdman> im trying to measure how long each GPIO input pin stays high. i think my logic is correct, but it isnt working. http://pastebin.com/hue5vjjM any ideas?
2012-06-05T13:41:14 < zyp> how is it not working?
2012-06-05T13:45:10 < upgrdman> when all pins on that port are low, currentInputValues never equals 0
2012-06-05T13:45:34 < upgrdman> i even configured pull downs for that port, but they should not be needed anyway
2012-06-05T13:45:59 < zyp> oh, right, so GPIO_ReadInputData() doesn't give you results as expected?
2012-06-05T13:46:50 < upgrdman> yes
2012-06-05T13:46:52 < zyp> did you consider that all ports are 16 bits wide, even though you're only using lower 8?
2012-06-05T13:46:59 < upgrdman> yes
2012-06-05T13:47:14 < upgrdman> oh i think i found the problem
2012-06-05T13:47:25 < upgrdman> one of the dev board periphs uses one of those pins
2012-06-05T13:47:27 < upgrdman> doh!
2012-06-05T13:48:31 < zyp> oh, and instead of doing a lot of if checks like that, you can compute changed pins like this: (prev ^ current)
2012-06-05T13:49:19 < zyp> ((prev ^ current) & current) will give you pins that just went high, and ((prev ^ current) & prev) will give you pins that just went low
2012-06-05T13:50:31 < upgrdman> well i need to update an array
2012-06-05T13:51:06 < zyp> yes, but you simplify the if tests that run 8 times by adding a calculation that only runs one time
2012-06-05T13:51:25 < zyp> sorry, I'm just obsessed with writing efficient code :p
2012-06-05T13:52:21 < upgrdman> ok
2012-06-05T14:07:20 < dongs> lol. i put fireworks on top of my quad (the kind that shoots out just one charge, but fairly loudly i guess) and it fired about 5 meters off hte ground, and must have jerked the quad enough that one of the props snapped

2012-06-05T14:22:06 < pelrun_> can't figure out why it isn't firing
2012-06-05T14:22:20 < pelrun_> should probably check to see if the vector is correct
2012-06-05T14:38:10 <+dekar> in case someone cares, I've updated TNT to Linaro GCC 4.7 - my resulting firmware shrunk by 150bytes and compiling seems quite a bit faster
2012-06-05T14:38:42 <+dekar> TNT now downloads the needed tarballs
2012-06-05T14:38:53 <+dekar> as well as extracts them
2012-06-05T14:39:15 < Laurenceb> 150bytes out of what size?
2012-06-05T14:39:20 <+dekar> 15kb
2012-06-05T14:39:24 < Laurenceb> lol
2012-06-05T14:39:27 < Laurenceb> not much
2012-06-05T14:39:41 <+dekar> yeah well, I just updated from gcc4.6 to 4.7
2012-06-05T14:39:42 < Laurenceb> what is tnt?
2012-06-05T14:39:45 <+dekar> I didn't expect much
2012-06-05T14:39:46 < Laurenceb> ah
2012-06-05T14:39:55 <+dekar> the official ##stm32 toolchain
2012-06-05T14:40:01 < Laurenceb> really
2012-06-05T14:40:11 < Laurenceb> hmm
2012-06-05T14:40:14 <+dekar> Thumb2 Newlib Toolchain
2012-06-05T14:40:17 < Laurenceb> better than codesourcery?
2012-06-05T14:40:42 <+dekar> yeah, I made TNT cause I didn't like they way they used newlib
2012-06-05T14:40:44 < zyp> dekar, no multilib?
2012-06-05T14:40:50 <+dekar> zyp, nope
2012-06-05T14:41:04 <+dekar> but feel free to add multilib if you care
2012-06-05T14:41:09 < Laurenceb> where can i download?
2012-06-05T14:41:23 < zyp> so, no F0 support and no utilization of M4 extensions in F4?
2012-06-05T14:41:24 <+dekar> https://github.com/EliasOenal/TNT
2012-06-05T14:41:46 <+dekar> zyp, add multilib and I'll gladly add it to the script
2012-06-05T14:41:55 < zyp> I'm just asking
2012-06-05T14:41:58 <+dekar> I only build for stm32f1
2012-06-05T14:42:44 < Laurenceb> looks good, ill try it laters
2012-06-05T14:43:04 <+dekar> I've only tried it on OSX so far so it probably needs some changes
2012-06-05T14:43:26 < Laurenceb> yeah i see the darwin stuff
2012-06-05T14:43:31 < Laurenceb> im running ubuntu
2012-06-05T14:44:31 < zyp> how is it, when you use hardfloat, do float functions use a different ABI?
2012-06-05T14:44:49 < zyp> i.e. pass float arguments in fpu regs
2012-06-05T14:47:04 < zyp> if that is the case, it's not a matter of libs compiled for cm3 being slow, it's a matter of libs compiled for cm3 not working when compiling an application for cm4f with hardfloat
2012-06-05T14:47:06 <+dekar> the main reason I made TNT was the lack of sane memory page sizes in codesourcery
2012-06-05T14:47:20 <+dekar> they compiled newlib with 4096byte pages
2012-06-05T14:47:26 < zyp> memory page sizes?
2012-06-05T14:47:28 < zyp> ah, right
2012-06-05T14:47:36 <+dekar> well for malloc
2012-06-05T14:47:46 < Laurenceb> interesting
2012-06-05T14:47:53 < zyp> so sbrk will be called with 4k increments, I guess
2012-06-05T14:48:01 <+dekar> yeah
2012-06-05T14:48:04 < Laurenceb> guess that explains the issues i was having
2012-06-05T14:48:11 <+dekar> for TNT newlib uses 128byte pages
2012-06-05T14:48:11 < Laurenceb> with malloc eating all my ram
2012-06-05T14:48:36 <+dekar> I also set some flags to make newlib smaller at the cost of speed
2012-06-05T14:48:44 < zyp> how does the paging in newlib malloc work?
2012-06-05T14:48:58 < zyp> does it affect anything more than sbrk increment size?
2012-06-05T14:49:54 <+dekar> I did't look into it that far, but I saw malloc failing on codesourcery when I had quite some memory left
2012-06-05T14:50:43 < zyp> would be more sane to just remove the sbrk stuff at all
2012-06-05T14:51:13 < Laurenceb> dekar: me too
2012-06-05T14:51:28 <+dekar> I guess so, but newlib was intended for use on top of operating systems

2012-06-05T14:52:02 < zyp> dekar, yes, on platforms with MMU, so sbrk can request more memory to be mapped up

2012-06-05T14:52:58 <+dekar> the 128byte pages work reasonably well though, so I am to lazy to patch it and get it upstream
2012-06-05T15:19:18 < pelrun_> blah, why has my linker script put a non-aligned address in a vector entry? :P
2012-06-05T15:19:27 < pelrun_> time to get the hammer out
2012-06-05T15:21:48 < Laurenceb> can anyone help me with github?
2012-06-05T15:21:58 < Laurenceb> i need to merge remote changes
2012-06-05T15:22:06 < zyp> pelrun_, because that's the way they are supposed to be
2012-06-05T15:22:09 < Laurenceb> from my github repo
2012-06-05T15:22:22 < Laurenceb> how do i do that?
2012-06-05T15:22:35 < zyp> Laurenceb, huh?
2012-06-05T15:23:13 < Laurenceb> i have changes A,B and C
2012-06-05T15:23:21 < Laurenceb> my local copy has A and C
2012-06-05T15:23:23 < pelrun_> zyp, oh, is the lower bit a flag?
2012-06-05T15:23:26 < Laurenceb> repo has B
2012-06-05T15:23:33 < Laurenceb> how do i do the merge?
2012-06-05T15:23:39 < zyp> pelrun_, yes, it indicates arm or thumb mode
2012-06-05T15:23:48 < zyp> and as stm32 is thumb only, it should always be 1
2012-06-05T15:24:30 < zyp> if you go ahead and force it to be 0, the cpu will throw a usagefault due to INVSTATE
2012-06-05T15:24:31 < Laurenceb> http://securfox.wordpress.com/2010/04/29/merge-the-remote-changes-before-pushing-again-not-a-fast-forward/
2012-06-05T15:24:31 < pelrun_> gotcha
2012-06-05T15:24:35 < Laurenceb> ^that?
2012-06-05T15:24:49 < pelrun_> didn't know they were thumb-only, that's interesting too
2012-06-05T15:25:05 < zyp> Laurenceb, what is the common ancestor?
2012-06-05T15:25:09  * pelrun_ wonders what else he missed
2012-06-05T15:25:21 < Laurenceb> its shared at point A
2012-06-05T15:25:37 < zyp> github has A -> B and you have A -> C?
2012-06-05T15:25:41 < Laurenceb> yes
2012-06-05T15:26:29 < zyp> and you are now in your local repo, in your github tracking branch?
2012-06-05T15:26:55 < Laurenceb> erm.. yeah
2012-06-05T15:27:00 < zyp> ok
2012-06-05T15:27:10 < zyp> first, run git fetch
2012-06-05T15:27:21 < zyp> then: git rebase origin/master
2012-06-05T15:27:41 < zyp> origin/master should refer to B, and rebase will move B on top of C
2012-06-05T15:27:46 < Laurenceb> like the link i posted?
2012-06-05T15:28:02 < zyp> ah, yes
2012-06-05T15:28:08 < zyp> it says pretty much the same
2012-06-05T15:28:34 < zyp> it's a bit more explicit with the arguments, but it's the same idea
2012-06-05T15:29:00 < zyp> oh
2012-06-05T15:29:02 < zyp> actually
2012-06-05T15:29:11 < zyp> you could just do this: git pull --rebase
2012-06-05T15:29:19 < zyp> it will be equivalent to fetch and rebase
2012-06-05T15:30:15 < Laurenceb> i see
2012-06-05T15:30:40 < zyp> you can also do a normal pull, but that would create a merge of B and C, instead of rebasing C
2012-06-05T15:30:52 < zyp> and that leads to pretty ugly history
2012-06-05T15:31:24 < Laurenceb> CONFLICT (content): Merge conflict in main.map

2012-06-05T15:32:51 < zyp> oh, right
2012-06-05T15:33:04 < Laurenceb> thats why i thought delete it

2012-06-05T15:33:16 < Laurenceb> it is
2012-06-05T15:33:18 < zyp> why are they in the repo in the first place?
2012-06-05T15:33:21 < Laurenceb> lol
2012-06-05T15:33:21 < zyp> that's dumb.
2012-06-05T15:34:10 < zyp> well, if you insist on having them in the repo, the right way now is to delete them and rebuild them from the merged sources
2012-06-05T15:34:26 < zyp> and if you don't, just delete them
2012-06-05T15:34:53 < zyp> *yawn*
2012-06-05T15:35:14 < zyp> actually, resolving merge conflicts is what I've been doing for work all day

2012-06-05T15:35:18 < Laurenceb> git push prigin master
2012-06-05T15:35:24 < Laurenceb> what does that mean?
2012-06-05T15:35:38 < zyp> pretty much same as git push
2012-06-05T15:35:47 < BrainDamage> puts prigin branch into repo named master

2012-06-05T15:36:07 < BrainDamage> ah right
2012-06-05T15:36:10 < zyp> push master branch into repo named origin
2012-06-05T15:36:13 < pelrun_> was using a ld_vl startup on the f1 discovery, which is an md_vl
2012-06-05T15:36:25 < zyp> origin is the default name for the main upstream server
2012-06-05T15:36:39 < BrainDamage> yeah, I was wondering why he picked such weird name
2012-06-05T15:36:47 < BrainDamage> didn't realize it was a typo
2012-06-05T15:37:27 < Laurenceb> seems to work now thanks
2012-06-05T15:37:41 < zyp> Laurenceb, are you sure?
2012-06-05T15:37:58 < Laurenceb> well... all the files look correct now
2012-06-05T15:37:59 < zyp> did you resolve the conflict, tell git that you resolved the conflict, and push the changes?
2012-06-05T15:38:04 < Laurenceb> and it compiles...
2012-06-05T15:38:17 < zyp> but is the repo in a valid state?
2012-06-05T15:38:33 < BrainDamage> remember that after resolving a merge conflict you have to issue a commit order
2012-06-05T15:38:38 < zyp> yes
2012-06-05T15:38:39 < BrainDamage> or the changes won't be saved
2012-06-05T15:39:07 < zyp> I've probably did that 20 times today
2012-06-05T15:40:41 < Laurenceb> it looks to have picked up all the correct changes
2012-06-05T15:40:44 < Laurenceb> https://github.com/Laurenceb/STM32-Logger
2012-06-05T15:41:41 < zyp> yeah, if push didn't give you any errors, you're all good
2012-06-05T15:42:22 < Laurenceb> now ill spend some time doing something insane
2012-06-05T15:42:30 < Laurenceb> like adding SMART status info
2012-06-05T15:43:04 < Laurenceb> grab pcb temperature data
2012-06-05T15:49:21 <+dekar> Laurenceb, I am just compiling TNT on Debian, seems to "just work" after commenting the DARWIN lines
2012-06-05T15:49:29 <+dekar> I'll add some ifdef
2012-06-05T15:49:31 < Laurenceb> cool
2012-06-05T15:49:35 < Laurenceb> ill try later
2012-06-05T15:49:59 < Laurenceb> currently trying to work ouyt if "scsi sense data" is actually SMART
2012-06-05T15:51:23 < Laurenceb> looks like its actually this?

2012-06-05T18:26:37 <+dekar> BrainDamage, Linaro 4.7
2012-06-05T18:27:22 <+dekar> [7], arm-linux-gnueabi doesn't sound like it is suited for stm32 anyway

2012-06-05T19:14:22 < zyp> hmm, good question
2012-06-05T19:15:07 < BrainDamage> F0 mounts a cortex M0
2012-06-05T19:15:20 < zyp> yes, and L1 is based on M3
2012-06-05T19:15:38 < zyp> M0 is less complex, so it should be cheaper at least
2012-06-05T19:16:12 < BrainDamage> yup, it's supposed to be even cheaper than F1 ( and it is )
2012-06-05T19:16:21 < jpa-> ah.. no axis misalignment after all, just that my heading calculation is very sensitive to any bias
2012-06-05T19:16:22 < BrainDamage> afaik they go to like 0.9$
2012-06-05T19:16:42 < Tectu> http://www.st.com/internet/mcu/class/1734.jsp?wt.mc_id=enews_may12_F0_learning
2012-06-05T19:16:52 < jpa-> and the bias wanders..
2012-06-05T19:17:06 < Tectu> not sure why there are needed 10000 different chips "versions"
2012-06-05T19:17:09 < zyp> power draw is kind of hard to answer, L1 could be more power efficient, i.e. more processing for the same amount of power
2012-06-05T19:17:21 < zyp> which translates into less power for the same amount of processing
2012-06-05T19:18:15 < BrainDamage> Tectu: most consumer design is all about fitting the cheapest components possible
2012-06-05T19:18:15 < karlp> different reasons for the different power too.
2012-06-05T19:18:27 < karlp> f0 cores are inhernetly lower power because they're tinier, and the core was designed for that.
2012-06-05T19:18:41 < karlp> L1 is low power because of process tricks.
2012-06-05T19:18:46 < BrainDamage> so having a broad spectrum of chips allows you potentially to save
2012-06-05T19:18:57 < zyp> karlp, but are they more power efficient?
2012-06-05T19:19:02 < karlp> you could implement the f0 IP on some very inefficient silicon processes,
2012-06-05T19:19:13 < karlp> zyp: like you say, hard to measure right now :)
2012-06-05T19:19:19 < zyp> ;)
2012-06-05T19:19:23 < karlp> I haven't looked at the sheets for the f0 closely enough
2012-06-05T19:19:37 < karlp> this is why you get dev boards :)
2012-06-05T19:19:56 < karlp> L1 does offer extra periphs designed to make low power apps work though
2012-06-05T19:20:10 < karlp> separate vbat domains and rtc's running in that domain and so on.
2012-06-05T19:20:20 < zyp> yeah
2012-06-05T19:20:27 < karlp> f0 gives you a bunch of power savings for free, just because it's a tiny core.
2012-06-05T19:20:31 < jpa-> L1 is lovely
2012-06-05T19:20:37 < zyp> I'm kind of suspecting an L0 in the future
2012-06-05T19:20:38 < karlp> L1 is pretty cool :)
2012-06-05T19:20:44 < karlp> yeah, I woudl foresee an L0 too :)
2012-06-05T19:20:45 < zyp> like L1 with M0

2012-06-05T22:49:41 < zyp> those are useful in a lot of cases
2012-06-05T22:50:45 < zyp> say you have a context struct, that will be created by an init() function
2012-06-05T22:51:24 < zyp> say you want the init function to return an error code, so it can't be used to return a pointer to the context
2012-06-05T22:51:48 < zyp> then you solve that by passing in a pointer to the context-pointer, so the function can write it

2012-06-06T01:02:54 < Tectu> feurig, still talking about my paste?
2012-06-06T01:04:08 < feurig> Sorry I came in late.
2012-06-06T01:05:04 < Tectu> this dosen't answer my question at all
2012-06-06T01:05:23 < feurig> (but .... your code the pointer to pointer malloc v xxx ...)
2012-06-06T01:05:42 < feurig> sorry I will scroll further up...
2012-06-06T01:08:24 < feurig> I think the use case presented (malloc) is one good reason to pass a pointer to a pointer.
2012-06-06T01:09:58 < feurig> and an array of struct pointers is not the same thing at all
2012-06-06T01:11:07 < feurig> but when ever I get into these issues and get confused I go back to k&r (which has been loaned out at the moment)
2012-06-06T01:11:42 < Tectu> yes, i'll take a look to my k&r
2012-06-06T01:11:53 < Tectu> confused about   **  and *foo[]   all the time...
2012-06-06T01:12:57 < feurig> I think it has to do with the way that structs are implimented. They happen to be pointers mostly.
2012-06-06T01:13:10 < feurig> and I also get lost in it.

2012-06-06T01:27:30 < zyp> are you meaning arrays when you say structs?
2012-06-06T01:29:46 < zyp> there is a major difference between an array and a pointer
2012-06-06T01:30:05 < zyp> a pointer is a variable containing a memory address
2012-06-06T01:31:31 < zyp> an array is an amount of variable bytes, but no space is consumed to store the address of it
2012-06-06T01:32:12 < zyp> the thing is that in C, the name of a pointer refers to the contents of the variable, i.e. the address
2012-06-06T01:33:16 -!- TitanMKD [Titan@chl26-1-88-183-104-56.fbx.proxad.net] has quit []
2012-06-06T01:33:48 < zyp> while the name of an array is either a global symbol that gets resolved at linking time (if it's a global variable) or an offset into the current stack frame (if it's a stack variable)
2012-06-06T01:34:11 < zyp> in either case, the name of an array resolves to the address of the array
2012-06-06T01:35:23 < zyp> it's not mutable, so it's pretty much a constant pointer, always pointing to the start of the array
2012-06-06T01:35:47 < zyp> pointing to the start of the array is the same as pointing to the first element in the array
2012-06-06T01:37:11 < Tectu> you're awesome

2012-06-06T01:39:30 < zyp> pointers are nothing magic, just stop thinking about them as pointers for a moment, and think about them as memory addresses instead
2012-06-06T01:41:04 < Tectu> but what's the difference between   **argv   and   *argv[]   ?
2012-06-06T01:41:22 < Tectu> because in    int main(int argc, char *argv[])   you see **argv  many times
2012-06-06T01:41:45 < zyp> as a function argument? none
2012-06-06T01:42:14 < zyp> consider this:
2012-06-06T01:42:25 < zyp> say we have a function that takes an array
2012-06-06T01:42:39 < zyp> we can declare it as foo(int x[])

2012-06-06T01:43:15 < zyp> you can then call it with an int-array as an argument
2012-06-06T01:43:34 < zyp> what happens then is that the address of the array will be passed in as an argument
2012-06-06T01:43:50 < karlp> does anyone know why this would block forever?: while (USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET)
2012-06-06T01:44:02 < Tectu> zyp, okay
2012-06-06T01:44:04 < zyp> then consider this: foo(int* x)
2012-06-06T01:44:05 < karlp> I'm guess I've not got something set up, or in the right order, but I'm damned if I know what I've left out.
2012-06-06T01:44:27 < Tectu> zyp, pointer to variable of type x
2012-06-06T01:44:27 < zyp> Tectu, you can call it with an int-pointer as an argument
2012-06-06T01:44:43 < Tectu> or we pass an array and increment pointer with sizeof(int)  ?
2012-06-06T01:44:48 < Tectu> to access other indexes
2012-06-06T01:44:54 < zyp> and what happens is that the address of the int will be passed in
2012-06-06T01:45:15 < Tectu> what do you mean?
2012-06-06T01:45:35 < zyp> this is a function declaration: foo(int* x)
2012-06-06T01:45:47 < zyp> of a function taking an int-pointer argument
2012-06-06T01:45:55 < Tectu> yes
2012-06-06T01:46:18 < zyp> when you call it, the value that will actually go into the register containing the argument is the address of the int being pointed to
2012-06-06T01:46:35 < Tectu> right
2012-06-06T01:46:38 < zyp> this is another function declaration: bar(int x[])
2012-06-06T01:46:45 < zyp> of a function taking an int-array argument
2012-06-06T01:46:56 < zyp> when you call it, the value that will actually go into the register containing the argument is the address of the first int in the array
2012-06-06T01:47:16 < zyp> do you now see how that is exactly the same thing?
2012-06-06T01:47:26 < Tectu> yes
2012-06-06T01:47:31 < zyp> good
2012-06-06T01:47:33 < Tectu> i knew that before
2012-06-06T01:47:36 < Tectu> i don't know about ** ;-)
2012-06-06T01:48:05 < zyp> now, consider that the type is not int, but a string, which in C is a char-pointer
2012-06-06T01:48:20 < Tectu> char *str ?
2012-06-06T01:48:59 < zyp> I prefer writing the * adjacent to the type rather than the name, since it's part of the type
2012-06-06T01:49:08 < Tectu> well
2012-06-06T01:49:34 < zyp> there are reasons for and against doing that, but let's not discuss them now
2012-06-06T01:49:43 < zyp> either way
2012-06-06T01:49:57 < Tectu> yeah, i see that the same way
2012-06-06T01:50:02 < zyp> consider that char* argv[] is an array of char-pointers
2012-06-06T01:50:24 < zyp> while char** argv is a pointer to the first char-pointer in that array
2012-06-06T01:50:42 < zyp> it's a char-pointer-pointer
2012-06-06T01:51:02 < zyp> char-pointer-pointer = char-pointer-array
2012-06-06T01:51:12 < Tectu> ahaaa!!!!!
2012-06-06T01:51:12 < zyp> exactly the same logic as int-pointer = int-array
2012-06-06T01:52:48 < Tectu> thank you very much!!!!
2012-06-06T01:52:53 < Tectu> this is now much clearer to me :D
2012-06-06T01:53:04 < zyp> good
2012-06-06T01:53:35 < zyp> oh, and there is a reason that there is two ways to write it
2012-06-06T01:53:49 < Tectu> why?
2012-06-06T01:54:01 < Tectu> wait, what exactly do you mean now?
2012-06-06T01:54:03 < zyp> pointer = array is only true for one-dimentional stuff
2012-06-06T01:54:05 < Tectu> to write what?
2012-06-06T01:54:09 < Tectu> okay
2012-06-06T01:54:12 < Tectu> i understand
2012-06-06T01:54:28 < zyp> two-dimentional pointers are pointers to pointers
2012-06-06T01:54:31 < Tectu> so it's much better when just using  *foo[]  instead of **foo ?
2012-06-06T01:55:11 < zyp> while two-dimentional arrays are just some index magic on top of a one-dimentional array
2012-06-06T01:55:26 < Tectu> how is a multidimensionl array build?
2012-06-06T01:55:36 < Tectu> like 10*10  -> is 100 entry 1D array?
2012-06-06T01:55:41 < Tectu> with a bit of wrapping magic?
2012-06-06T01:55:42 < zyp> exactly
2012-06-06T01:55:58 < Tectu> aye
2012-06-06T01:56:27 < Tectu> i am off for now
2012-06-06T01:56:31 < zyp> int x[][] = {{1, 2, 3}, {4, 5, 6}, {7, 8, 9}}; is stored as int x[] = {1, 2, 3, 4, 5, 6, 7, 8, 9};

2012-06-06T02:23:35 < zyp> I'm pretty sure row-major order is guaranteed by c spec
2012-06-06T02:27:44 < zyp> yep
2012-06-06T02:27:53 < zyp> spec says «blah blah … It follows from this
2012-06-06T02:27:54 < zyp> that arrays are stored in row-major order (last subscript varies fastest).»

2012-06-06T09:44:10 < zyp> I'm doing c++ on stm32, but no stl :p
2012-06-06T09:51:57 < pelrun_> yeah, I think it's probably a good idea to continue that behaviour :)
2012-06-06T09:52:29 < pelrun_> oh goodie, eclipse didn't barf when I replaced my C-nature project files with C++ ones
2012-06-06T09:59:12 < Thorn> c++ templates are inlined if you do them right, remember. lots of optimization opportunities
2012-06-06T09:59:50 < Thorn> c++ catches much more errors at compile time too (again if you use it right)
2012-06-06T10:02:55 < pelrun_> oh sure
2012-06-06T10:03:21 < pelrun_> you just probably don't want to spend 90K on the STL.
2012-06-06T10:04:15 < pelrun_> although it's not such a big deal if you're using an F4 with 1MB of flash :o
2012-06-06T10:05:48 < zyp> my code is currently 7k or so
2012-06-06T10:05:55 < zyp> :p
2012-06-06T10:06:38 < Thorn> I imagine that stl heavily uses malloc() internally (in the form of operator new)
2012-06-06T10:06:49 < Thorn> that's even worse on an embedded system
2012-06-06T10:07:37 < Thorn> I think someone tried to implement something like iostreams for embedded systems, maybe string too
2012-06-06T10:07:59 < zyp> I implemented a memory pool with smart pointers
2012-06-06T10:08:55 < zyp> http://cgit.jvnv.net/suzumebachi/tree/os/pool.h
2012-06-06T10:09:09 < zyp> it's experimental, it works, but it's probably not the best way of doing stuff
2012-06-06T10:09:31 < zyp> I'm redoing it when I get around to it
2012-06-06T10:28:40 < pelrun_> I just try to stick with stack and static global allocation as much as humanly possible
2012-06-06T10:29:13 < pelrun_> refactoring this dodgy little serial library I wrote to use C++ should help me eliminate a few mallocs for buffers
2012-06-06T10:29:49 < pelrun_> although I could probably have done it with structs just as easily

2012-06-06T12:07:07 < Tectu> okay, i didn't

2012-06-06T12:13:37 < karlp> dahfuq
2012-06-06T12:14:08 < Tectu> karlp, what?
2012-06-06T12:17:04 < karlp> copied the libopencm3/examples/stm32/f2/jobygps/usart_printf
2012-06-06T12:17:13 < karlp> and it's linked in a whole heap of arm code, instead of thumb2 code.
2012-06-06T12:17:26 < karlp> so it doesn't work :)
2012-06-06T12:20:45 <+dekar> *cough* TNT *cough*
2012-06-06T12:20:58 < Tectu> aye, this makes me asking questions :D
2012-06-06T12:21:11 < Tectu> thumb is the "shorted" instructionset  -> 16 bit adresses instead of 32
2012-06-06T12:21:12 < Tectu> right?
2012-06-06T12:21:40 <+dekar> Tectu, thumb1 or thumb2?
2012-06-06T12:21:50 <+dekar> thumb2 has many 32bit opcodes
2012-06-06T12:21:52 < Tectu> dekar, dunno :D
2012-06-06T12:21:56 < Tectu> i guess thumb1
2012-06-06T12:22:04 < Tectu> just have j  -mthumb  here
2012-06-06T12:22:04 <+dekar> thumb1 is 16bit only
2012-06-06T12:22:14 < Tectu> yeah
2012-06-06T12:22:15 <+dekar> but you should never use thumb1, it is horribly slow
2012-06-06T12:22:57 < Tectu> i have    TOPT = -mthumb -DTHUMB     in Makefile here
2012-06-06T12:23:02 < Tectu> so i guess thumb1?
2012-06-06T12:23:08 < karlp> dekar: TNT works because it's not multilib?
2012-06-06T12:23:14 < karlp> cm3 _only_ :)
2012-06-06T12:23:29 <+dekar> ya :)
2012-06-06T12:24:09 < Tectu> dekar, why is it slower?
2012-06-06T12:24:21 < Tectu> it is just a smaller address space for the instructions?
2012-06-06T12:24:47 <+dekar> Tectu, thumb1 has no division opcode for example
2012-06-06T12:24:59 < Tectu> i have no idea what this means :D
2012-06-06T12:25:12 < karlp> thumb2 has 32bit opcodes?
2012-06-06T12:25:15 <+dekar> 10 / 2 = 5
2012-06-06T12:25:16 < karlp> I didn't know that?
2012-06-06T12:25:31 < karlp> I thought the evidence of 32bit opcodes in objdump -d was proof that the wrong things had been linked in?
2012-06-06T12:25:41 <+dekar> 10 / 2 = 5 is one opcode in thumb2, but a bunch of them in thumb1

2012-06-06T12:26:47 < Tectu> can i just change my chibios demo Makefile from thumb1 to thumb2 without breaking anything?
2012-06-06T12:26:59 <+dekar> also thumb2 has stuff like ITEEE (IF-THEN-ELSE-ELSE-ELSE)
2012-06-06T12:27:20 <+dekar> which is quite funny for assembly imo
2012-06-06T12:27:52 <+dekar> -mthumb can also generate thumb2 btw, I think gcc looks at the arch
2012-06-06T12:30:12 < zyp> ITE is used to make arm-compatible assembly
2012-06-06T12:30:27 < cjbaird> ITEEE sounds like something from the VAX instruction set... (which also had instructions for FP polynominals..)
2012-06-06T12:31:57 < zyp> the thing is that arm has a «unified assembly language», where the same mnemonics can assemble both into arm and thumb/thumb2 instructions
2012-06-06T12:32:20 < zyp> arm instructions can be conditional, thumb can not
2012-06-06T12:32:52 < Tectu> okay... so here we go:   i have an external interrupt on PC4, but now i want one on PA4 too. can i do that or not? afaik there are only 16 channels?
2012-06-06T12:32:58 <+dekar> yeah the conditional stuff was awesome
2012-06-06T12:33:12 <+dekar> also the barrel shift
2012-06-06T12:33:48 < zyp> thumb2 remedies this by prefixing the conditional instructions with a new instruction making them conditional, this is IT, ITE, ITEEE, ITTTT or whatever you make of it
2012-06-06T12:34:08 < zyp> when same code is assembled for arm rather than thumb, the IT* will be ignored
2012-06-06T12:35:43 <+dekar> the bottom-line is, use thumb2! :D
2012-06-06T12:36:26 < zyp> and yes, I believe -mthumb only says «disallow arm»
2012-06-06T12:39:32 < Tectu> so i am fine with -mthumb ?
2012-06-06T12:39:48 < Thorn> oh lol http://electronics.stackexchange.com/questions/33364/my-can-node-trasmits-but-cant-receive-in-the-receiver-node-why
2012-06-06T12:40:45 <+dekar> Tectu, just write some code performing an division and see if it uses div or udiv
2012-06-06T12:41:13 <+dekar> or cbz (compare branch zero), which I think is thumb2-only as well
2012-06-06T12:41:34 <+dekar> it's been quite some time since I did arm assembly

2012-06-06T15:03:41 < cjbaird> I hate it when that happens..

2012-06-06T15:48:08 < karlp> well, TNT builds code that looks like it works, ie, memset is 16bit opcodes, not arm opcodes, but doesn't actually run.
2012-06-06T16:00:06 < Laurenceb> oops
2012-06-06T16:00:16 < Laurenceb> and i was just about to install it
2012-06-06T16:04:41 < karlp> well, it looks good.
2012-06-06T16:04:55 < karlp> bloody mess.
2012-06-06T16:05:25 < karlp> gcc from launchpad works, but if I install the libopencm3 libs _into_ that, it starts linking in arm libs instead.
2012-06-06T16:05:44 < karlp> if I put the libopencm3 libs in /opt/somewhere/else it correctly pulls in the armv7-m libs.
2012-06-06T16:34:39 < Tectu> someone here using minicom?
2012-06-06T16:37:08 < zyp> karlp, so, when you build libopencm3 as a library, how specific will it be?
2012-06-06T16:38:56 < karlp> it builds separate f1, f2, f4 libraries
2012-06-06T16:39:57 < zyp> so it normally builds for all supported devices?
2012-06-06T16:40:53 < karlp> and yeah
2012-06-06T16:40:57 < dongs> what the hell is "sq()"?
2012-06-06T16:41:07 < karlp> though it looks like the f4 one still says m3, at least according to -readelf
2012-06-06T16:41:13 < zyp> I see
2012-06-06T16:41:17 < karlp> but I fail massively at getting these libs to work properly.
2012-06-06T16:41:31 < dongs> oh lulz
2012-06-06T16:41:33 < dongs> #ifndef sq
2012-06-06T16:41:33 < dongs> #define sq(x) ((x)*(x))
2012-06-06T16:41:46 < zyp> sq(x++)
2012-06-06T16:41:47 < karlp> I've at least got _a_ way of building with stdlib and having memset and so on,
2012-06-06T16:42:05 < karlp> but I don't understand why I haven't had it working before, or why _this_ way works, but no other wya.
2012-06-06T16:42:10 < karlp> so I'm ignoring it for now.
2012-06-06T16:42:31 < karlp> is it reasonable to use interrupts for rx serial, and dma for tx?
2012-06-06T16:42:40 < karlp> tx is known lengths,
2012-06-06T16:42:46 < karlp> rx is noisy from other people on the line.
2012-06-06T16:42:52 < zyp> I'm going to take another approach with my library
2012-06-06T16:43:17 < zyp> rather than building a seperate library, I'm planning to include it in projects as a git submodule
2012-06-06T16:43:17 < karlp> or do people tend to use dma only or interrupts only for this?
2012-06-06T16:43:41 < karlp> yeah, that's sort of what I was doing in my own hacking,
2012-06-06T16:43:46 < zyp> then git would keep track of which lib version that works with a certain project version
2012-06-06T16:44:35 < zyp> http://paste.jvnv.net/view/KAkYm <- did I already show you this?
2012-06-06T16:44:50 < zyp> I was playing around with that last weekend
2012-06-06T16:45:05 < zyp> the idea here is that «foo» would be the submodule directory
2012-06-06T16:45:18 < zyp> and the SConscript in there will add the two new commands
2012-06-06T16:45:36 < Laurenceb> karlp: i do that with usart
2012-06-06T16:45:42 < zyp> the first will initialize the environment for that specific chip and choose correct flags and linker script and everything
2012-06-06T16:45:43 < Laurenceb> due to lame dma conflicts
2012-06-06T16:45:56 < Laurenceb> f1 dma sucks
2012-06-06T16:46:14 < karlp> well, the only dma I would be using is for the serial port,
2012-06-06T16:46:15 < zyp> and then the second will take the list of sources I supply, add the list of library sources and compile them all
2012-06-06T16:46:58 < zyp> the idea is to reduce the amount of boilerplate code required to get started on a new project

2012-06-06T21:12:20 < FUZxxl> Hi there!
2012-06-06T21:12:38 < FUZxxl> Did anybody of you had this bug: https://github.com/texane/stlink/issues/89 ?
2012-06-06T21:15:58 < karlp> not really enough of a bug I think anyone's in any hurry to fix
2012-06-06T21:16:03 < karlp> the examples are starting points at best.
2012-06-06T21:16:26 < karlp> and most of the examples in texane/stlink are of dubious quality
2012-06-06T21:17:08 < karlp> oh jpa: do you happen to know what firmware you have on y our VL board's stlink?
2012-06-06T21:17:29 < karlp> I just was back in windows, and tried the windows stlink tool, and it offered to upgrade me from v1.j11.s0 to v1.j12.so,
2012-06-06T21:17:30 < FUZxxl> karlp: What I don't understand is: The example basically calls into the libraries shipped by ST.
2012-06-06T21:17:38 < karlp> and it seems to be much more reliable so far
2012-06-06T21:17:41 < FUZxxl> There isn't much that can go wrong.
2012-06-06T21:17:51 < karlp> no-one said the examples from st were right
2012-06-06T21:17:51 < jpa-> karlp: no idea
2012-06-06T21:18:20 < karlp> the lcd files for instance have rather odd encodings in the files :)
2012-06-06T21:19:26 < FUZxxl> karlp: Yeah. That might be possible.
2012-06-06T21:19:46 < FUZxxl> Anyway, the specs are quite readable. It shouldn't be too difficult to implement that stuff by hand.
2012-06-06T21:20:11 < FUZxxl> If I want to write my own program for that board from scratch, is there anything I need to pay attention to?
2012-06-06T21:20:53 < karlp> yeah, don't follow the examples in stlink as to how to do it :)
2012-06-06T21:20:59 < karlp> otherwise, the world's your oyster.
2012-06-06T21:21:13 < FUZxxl> karlp: Yeah... They even use a nop-loop for delay...
2012-06-06T21:21:21 < FUZxxl> It's no fun to debug that.
2012-06-06T21:21:30 < FUZxxl> gdb just single-steps the loop...
2012-06-06T21:21:37 < FUZxxl> 100000 times
2012-06-06T21:21:48 < FUZxxl> in super-slow-motion
2012-06-06T21:37:17 < karlp> wow.
2012-06-06T21:37:35 < karlp> I actually got modbus code ported to stm32 in a day.
2012-06-06T21:37:49 < karlp> took a few months of faffing around at home, but whee
2012-06-06T21:38:52 < karlp> libopencm3 has some nice examples for dma and irq driven usarts.
2012-06-06T21:39:01 < karlp> I hadn't even used the usarts in my faffing around at home.

2012-06-06T22:01:56 < R2COM> im looking now at GPIO_Init function of CMSIS
2012-06-06T22:02:02 < Laurenceb_> is TNT working?
2012-06-06T22:02:09 < R2COM> so i was thinking before that CMSIS is just a matter of redefining things
2012-06-06T22:02:13 <+Steffanx> Not for me Laurenceb_
2012-06-06T22:02:23 < Laurenceb_>  :-/
2012-06-06T22:02:25 < R2COM> and that messing around and rewriting CMSIS would not give you any performance gain
2012-06-06T22:02:36 < R2COM> that its only about register and namespace definitions
2012-06-06T22:02:37 < R2COM> but
2012-06-06T22:02:59 < R2COM> i noticed that in GPIO_Init for example function, there are things which are wasting processor speed for stuff which could be defined

2012-06-06T22:04:01 <+Steffanx> Just write to the registers yourself when you want the 'optimal'  performance?

2012-06-06T22:05:24 < R2COM> i'v got to take a look..
2012-06-06T22:05:28 < zyp> are you sure any resources are wasted?
2012-06-06T22:05:45 < R2COM> zyp: for loop loads processor, you dont think so
2012-06-06T22:05:55 < R2COM> its a function
2012-06-06T22:06:04 < zyp> so what?
2012-06-06T22:06:20 < zyp> the loop arguments are static, so it's easy for the compiler to unroll
2012-06-06T22:06:23 < R2COM> so, nothing, my point is that there are things done in CMSIS which could be done more effectively
2012-06-06T22:06:47 < zyp> and if all the numbers are constant, that entire loop can probably be reduced to a few register accesses
2012-06-06T22:06:58 < zyp> ah, no
2012-06-06T22:07:00 < R2COM> whatever
2012-06-06T22:07:10 < zyp> there's actual register accesses in the look
2012-06-06T22:07:15 < zyp> ok, I agree, it's horrible
2012-06-06T22:07:28 < zyp> s/look/loop/
2012-06-06T22:07:50 < R2COM> i'll explore more and see if similar shit happens in other functions
2012-06-06T22:08:10 < R2COM> now, at this stage im starting to think that it probably makes sense to have your own stuff
2012-06-06T22:08:14 < R2COM> not that CMSIS thingy
2012-06-06T22:08:46 < R2COM> its just CMSIS is there and works, and it takes much less time to get something done with it right now
2012-06-06T22:08:47 < zyp> sure
2012-06-06T22:08:55 < R2COM> if one is just starting with stm32
2012-06-06T22:09:10 <+Steffanx> Nah, with the cmsis i had actually no idea what i was doing
2012-06-06T22:09:24 <+Steffanx> no idea.. as in not 100% sure :P
2012-06-06T22:09:38 < zyp> I'm currently in the process of wrapping up my stuff so it's more reusable
2012-06-06T22:10:07 < zyp> but I don't know if I want to go around and suggest it to everyone, then I suddenly have an obligation to maintain it for everyone
2012-06-06T22:10:14 < zyp> :p
2012-06-06T22:10:19 <+Steffanx> Lazy .. lazy
2012-06-06T22:10:26 < R2COM> why, no obligation
2012-06-06T22:10:39 < zyp> :p
2012-06-06T22:10:46 < R2COM> if someone likes it, he picks up and reuses, if not then he can develop his own or fuck himself
2012-06-06T22:11:14 < zyp> yeah, I think that's the way I'm going to go about it
2012-06-06T22:11:25 < zyp> use it if you want, patches accepted
2012-06-06T22:11:35 <+Steffanx> Lazy++
2012-06-06T22:11:39 < zyp> :D
2012-06-06T22:12:07 < zyp> maybe I should call it that
2012-06-06T22:12:11 <+Steffanx> Ha :P
2012-06-06T22:12:19 < zombiefeurig> beats lazy#
2012-06-06T22:12:33 < zyp> aww, there is already a liblazy
2012-06-06T22:12:44 < zombiefeurig> pronounced lay zee pound
2012-06-06T22:13:29 <+Steffanx> pound?
2012-06-06T22:13:33 < zyp> #
2012-06-06T22:14:02 < zyp> some people call it hash and some call it pound
2012-06-06T22:14:03 <+Steffanx> ARh, American English ..
2012-06-06T22:14:10 <+Steffanx> Americans and their english => trash
2012-06-06T22:14:12 <+Steffanx> :P
2012-06-06T22:14:16 < zyp> and in norway people tend to call it firkant
2012-06-06T22:14:30 <+Steffanx> Hekje :)
2012-06-06T22:15:09 < zombiefeurig> nothing particularly sharp comes out of Micro$oft
2012-06-06T22:15:43 <+Steffanx> Blablablabla
2012-06-06T22:15:53 < zyp> Steffanx, agreed
2012-06-06T22:16:36 < zyp> ms-bashers are about as uninteresting as dongs is when he's bashing non-ms-stuff
2012-06-06T22:16:44 <+Steffanx> lunix ftw
2012-06-06T22:16:54 <+Steffanx> Anyway has an idea why dekars build script would fail with

2012-06-06T22:17:05 <+Steffanx> ?
2012-06-06T22:17:17 <+Steffanx> It's the script from the topic
2012-06-06T22:17:21 < zyp> v6s-m?
2012-06-06T22:17:24 < Laurenceb_> firkat?
2012-06-06T22:17:30 <+Steffanx> nt
2012-06-06T22:17:32 < Laurenceb_> oh
2012-06-06T22:17:39 < Laurenceb_> i thought it involved furries
2012-06-06T22:18:10 < Laurenceb_> which always gets my attention
2012-06-06T22:19:13 <+Steffanx> Yeah, i don't know zyp
2012-06-06T22:20:41 < zombiefeurig> well Steffanx there is the fact that it is English.
2012-06-06T22:20:49 < zombiefeurig> an arbitrary language at best
2012-06-06T22:21:12 < zippe> It's a sharp
2012-06-06T22:21:18 < zippe> As any musician will tell you
2012-06-06T22:21:22 <+Steffanx> No a pound
2012-06-06T22:21:36 < zippe> C# is C sharp, not C pound
2012-06-06T22:21:40 <+Steffanx> :P
2012-06-06T22:21:49 < zippe> QED
2012-06-06T22:22:03 < zyp> no, it's a preprocessor/comment character!
2012-06-06T22:22:20 < zippe> steffan, my guess is bogus multilib config
2012-06-06T22:22:46 < zippe> Though I don't know this script you speak of
2012-06-06T22:23:14 < R2COM> do you use stm32_flash.ld linker script located in TRUEstudio folder always by default, or people use different one, or do some modifications?
2012-06-06T22:23:23 <+Steffanx> It looks like a hacky/not too much work script zippe
2012-06-06T22:23:25 <+Steffanx> https://github.com/EliasOenal/TNT/blob/master/toolchain.sh
2012-06-06T22:25:35 < R2COM> or .. if one doesnt use CMSIS, do they just borrow that linker script from that stuff, or use something else?
2012-06-06T22:25:58 < R2COM> im just wondering is there something else which could be done better than it is now or no
2012-06-06T22:26:05 < R2COM> or more properly..?
2012-06-06T22:26:10 <+Steffanx> I use zyps linker script
2012-06-06T22:35:41 < karlp> R2COM: a) gpio_init isn't CMSIS, it's ST's std periph lib.
2012-06-06T22:36:30 < R2COM> yes, right
2012-06-06T22:36:42 < karlp> b) the loop is presumably because you can use that function to init multiple pins at once.  yes, it could be done more efficiently, if you want more efficiency, I'm sure there are some tools vendors who'd love to take your money
2012-06-06T22:38:08 < karlp> some people call # hash too, not sharp or pound :)
2012-06-06T22:39:45 < R2COM> well, yea what im thinking is, i still might stick to CMSIS and ST's stdperiph for beginning
2012-06-06T22:40:57 < karlp> I was extremely happy with the progress I made with libopencm3 starting from last night to now, as opposed to stdperiph lib, but lgpl may not be to your liking.
2012-06-06T22:41:31 < karlp> though part of that was the examples, perhaps more so than the library itself
2012-06-06T22:41:40 < R2COM> is libopencm3 betteer than ST's stdperiph ?
2012-06-06T22:41:46 < karlp> depends what you want.
2012-06-06T22:41:55 < karlp> one of them accepts patches.
2012-06-06T22:41:56 < R2COM> what do you mean?
2012-06-06T22:43:08 < R2COM> so, is it a library with more efficient functions? faster? better..or what?
2012-06-06T22:43:26 < karlp> if you care about efficiency at this point, ur doin it rong
2012-06-06T22:43:43 < R2COM> you mean at the beginning point of exploring stm32?

2012-06-06T23:55:48 < zyp> sure

2012-06-06T23:56:48 < zyp> yep
2012-06-06T23:56:52 < R2COM> hmm...
2012-06-06T23:57:00 < zyp> no need for doing it in assembly
2012-06-06T23:57:04 < R2COM> i see some assembly in the .s file coming from CMSIS
2012-06-06T23:57:05 < R2COM> ?
2012-06-06T23:57:10 < R2COM> you sure?
2012-06-06T23:57:20 < zyp> of course I'm sure, my code works.
--- Day changed Thu Jun 07 2012
2012-06-07T00:01:05 < karlp> R2COM: being able to write startup code in c was a selling point from arm
2012-06-07T00:01:30 < karlp> people pushing asm ones are presumably just reusing the ones they already had from armv6
2012-06-07T00:02:18 < zyp> http://cgit.jvnv.net/potetmos/tree/kernel/entry.c <- I wrote some startup code for x86 a few years ago as well
2012-06-07T00:02:19 < R2COM> hm ok
2012-06-07T00:02:36 < zyp> but I couldn't get away without a few lines of inline assembly there :p
2012-06-07T00:02:55 < zyp> mostly because I had to set up stack before entering a C function
2012-06-07T00:03:04 < R2COM> also, by the way, im using code sourcery
2012-06-07T00:03:06 < R2COM> compiler
2012-06-07T00:03:08 < R2COM> not summon arm
2012-06-07T00:03:12 < zyp> on cortex-m, stack is initialized by hardware before reset handler is called
2012-06-07T00:04:06 < zyp> C functions expect a valid stack pointer when they are called
2012-06-07T00:04:43 < R2COM> well.
2012-06-07T00:04:59 < karlp> what are you ini_array and fini_array sections for zyp?
2012-06-07T00:04:59 < R2COM> dont know... so would you recommend go ahead with CMSIS and stdperiph then for beginning?
2012-06-07T00:05:13 < zyp> karlp, global constructors/destructors
2012-06-07T00:05:40 < zyp> those sections are created by the compiler
2012-06-07T00:05:54 < zyp> it contains lists of function pointers to call at startup/end
2012-06-07T00:05:55 < karlp> glue7t? is that some sort of arm interworking stuff?
2012-06-07T00:06:27 < zyp> hmm, might be
2012-06-07T00:06:38 < karlp> so many linker scripts out there,
2012-06-07T00:06:59 < zyp> I made a bunch of new ones today
2012-06-07T00:07:02 < karlp> some do most things, seems to always be floating bits that might be important for something, but no-one always knows why/what
2012-06-07T00:07:31 < zyp> http://paste.jvnv.net/view/BB8d3 <- the new ones reads like this
2012-06-07T00:07:38 < zyp> have one for each flash size
2012-06-07T00:07:41 < karlp> yeah, that's more like it :)
2012-06-07T00:07:51 < karlp> that's how mine and the libopencm3 ones look
2012-06-07T00:09:20 < zyp> I'm going to add another section, like .bss but uninitialized, for stacks
2012-06-07T00:09:37 < zyp> then put it into ccm on devices with ccm, ram on others
2012-06-07T00:09:52 < zyp> and keep a strict «no dma to stack» policy
2012-06-07T00:10:07 < karlp> what's ccm again?
2012-06-07T00:10:13 < zyp> core coupled memory
2012-06-07T00:10:29 < zyp> i.e. directly on proc's data bus
2012-06-07T00:10:37 < zyp> so it's only available from proc
2012-06-07T00:11:51 < zyp> seems reasonable to put stacks there, stack is probably the most active part of memory except dma buffers
2012-06-07T00:12:19 < zyp> then the processor will never have to wait for arbitration to use stacks

2012-06-07T00:25:14 < zippe> karlp: ini_array is for static constructors; fini_array for destructors
2012-06-07T00:25:24 < zippe> fini_array is usually meaningless for an embedded target
2012-06-07T00:26:15 < zippe> zyp: You know that you can #include in linker scripts?  So you can have a master for each memory size that includes the generic script for your program layout?
2012-06-07T00:26:54 < zippe> glue7t is interworking, you can toss it

2012-06-07T01:03:00 < R2COM> zyp: what is hal_init() in your startup file? is it something like SystemInit() in CMSIS startup.s file?
2012-06-07T01:03:35 < zyp> probably
2012-06-07T01:03:53 < zyp> it calls rcc_init() that sets up the clocks and switches to full speed
2012-06-07T01:04:28 < zyp> I do it before performing all the initialization, so initialization goes faster ;)
2012-06-07T01:10:36 < R2COM> yeah
2012-06-07T01:10:47 < R2COM> i see in startup.s its done after initialization
2012-06-07T01:10:57 < R2COM> well...continuing study of CMSIS/stdperiph
2012-06-07T01:11:11 < R2COM> i'll probably write first few projects with that shit
2012-06-07T01:11:30 < R2COM> i think once you figure things out, its not difficult to transfer to custom library all stuff you have
2012-06-07T01:19:26 < Laurenceb_> i see
2012-06-07T01:19:33 < Laurenceb_> so whats the advantage of the ccm?
2012-06-07T01:20:41 < zyp> it's cheaper than having another slave on the AHB matrix :p
2012-06-07T01:21:05 < zyp> and since only the cpu can access it, it don't risk having to compete for it
2012-06-07T01:24:40 < zippe> It's almost certainly just another slave on the PL301

2012-06-07T01:26:38 < zippe> Instead of "put these bits into this register" you make a structure and call eight functions
2012-06-07T01:26:53 < zippe> It doesn't actually *do* anything
2012-06-07T01:27:03 < zippe> Like, there is no timer abstraction
2012-06-07T01:27:05 < R2COM> nuttx is RTOS ... i dont want rtos
2012-06-07T01:27:21 < zippe> I didn't say you did; you asked what I use, I told you
2012-06-07T01:27:42 < R2COM> and, do you use CMSIS?
2012-06-07T01:27:45 < zippe> No
2012-06-07T01:27:54 < zippe> Or more specifically, I use the dsplib
2012-06-07T01:27:57 < R2COM> just use custom definitions?
2012-06-07T01:27:58 < R2COM> ok
2012-06-07T01:28:15 < R2COM> hm
2012-06-07T01:28:29 < R2COM> is that your custom thing or what?
2012-06-07T01:29:20 < R2COM> i found DSP_lib within CMSIS folder
2012-06-07T01:30:04 < zippe> dsplib contains actual, real, useful algorithms
2012-06-07T01:30:10 < zippe> cmsis is mostly defines, but often useful
2012-06-07T01:30:45 < R2COM> yeah the defines
2012-06-07T01:53:01 < R2COM> im looking in stdlib, at here:
2012-06-07T01:53:03 < R2COM> #define RCC_APB1Periph_TIM2              ((uint32_t)0x00000001)
2012-06-07T01:53:23 < R2COM> in the datasheet i see for register map this:
2012-06-07T01:53:24 < R2COM> 0x4000 0000 - 0x4000 03FF TIM2
2012-06-07T01:53:37 < R2COM> kind of doesnt make sense
2012-06-07T01:53:48 < zyp> it's different things
2012-06-07T01:54:04 < R2COM> oh rcc
2012-06-07T01:54:06 < zyp> the define is for the bit in RCC_AHB1ENR
2012-06-07T01:55:43 < R2COM> APB1ENR
2012-06-07T01:56:43 < R2COM> but there, TIM2 is at bit 0
2012-06-07T01:56:46 < R2COM> not 1
2012-06-07T01:56:52 < zyp> of course
2012-06-07T01:57:01 < zyp> 1 is bit 0 set
2012-06-07T01:57:11 < R2COM> oh yea that way
2012-06-07T01:57:13 < R2COM> ok
2012-06-07T02:17:35 < R2COM> there is weird redundancy with that stdperiph library: in a file stm32f4xx.h there is this "#define  RCC_APB1ENR_TIM2EN                  ((uint32_t)0x00000001)" which is in comment called bit definitions for RCC_APB1ENR register, and then in the file stm32f4xx_rcc.h there is this "#define RCC_APB1Periph_TIM2              ((uint32_t)0x00000001)
2012-06-07T02:17:36 < R2COM> " and that is commented as RCC_APB1_Peripherals... why have these same things in two separate files...whole stuff gets bigger with no reason
2012-06-07T02:31:03 < Tectu> well
2012-06-07T02:31:08 < Tectu> how's it going
2012-06-07T02:32:36 < zyp> R2COM, doesn't really matter though, it's just defines
2012-06-07T02:32:46 < zyp> havng two doesn't affect source size at all
2012-06-07T02:33:17 < R2COM> i know, im just saying in terms of mess
2012-06-07T02:33:19 < R2COM> its a mess

2012-06-07T03:15:10 < dongs> i think (?) cmsis is by arm and bits by vendors while stdperiph is 100% st
2012-06-07T03:21:14 < R2COM> if i want for example, to redefine some register myself, but, i want later on  to be able to view it using p/x MYREG in gdb, how would i define it?
2012-06-07T03:21:24 < R2COM> or, what is a way to achieve that
2012-06-07T03:21:48 < dongs> i duno all my IDEs that I use have a 'register' or 'peripheral' view that shows all the stuff
2012-06-07T03:22:56 < R2COM> hmm
2012-06-07T03:23:03 < R2COM> im using just text gdb under linux

2012-06-07T03:39:20 < R2COM> when on the datasheet its on 3rd position

2012-06-07T03:41:16 < zippe> R2COM: If you want the debugger to know about register locations, then you need symbols for them
2012-06-07T03:41:55 < zippe> You can either use something like
2012-06-07T03:42:11 < zippe> volatile uint32_t *pMYREG = MYREG_ADDRESS
2012-06-07T03:42:20 < zippe> and then p/x *pMYREG
2012-06-07T03:42:54 < R2COM> hm ok thanx
2012-06-07T03:43:53 < R2COM> and in that case of course it will consume memory space
2012-06-07T03:44:05 < zippe> or you can use the linker to construct symbols for everything.  That's kinda messy though, and if you turn on link-time garbage collection you will probably only have defs for the ones you actually use
2012-06-07T03:44:31 < zippe> it won't consume memory if you put the definitions in a header
2012-06-07T03:44:52 < zippe> volatile uint32 * const pMYREG = MYREG_ADDRESS
2012-06-07T03:45:32 < zippe> That's a constant expression the same as (volatile uint32 *)MYREG_ADDRESS
2012-06-07T03:45:53 < R2COM> hm so its the best way to do it then i guess
2012-06-07T03:46:22 < zippe> Actually, sorry, cross-toolchain confusion
2012-06-07T03:46:40 < zippe> I'm not certain that if you don't have a copy of the value in memory that the compiler won't optimise it to the point where the debugger can't find it
2012-06-07T03:46:49 < zippe> You should try
2012-06-07T03:46:59 < zippe> Separately though, you're better off writing a debugger script to do what you want
2012-06-07T03:47:13 < R2COM> ok
2012-06-07T03:47:45 < R2COM> by the way, i like 0b00000100 stuff better
2012-06-07T03:47:49 < R2COM> than in hex
2012-06-07T03:48:31 < zippe> I prefer (1<<3) myself, but you should learn to read them all
2012-06-07T03:48:52 < R2COM> i know, it just didnt come into my mind they did that
2012-06-07T03:48:59 < R2COM> i do read hex

2012-06-07T04:19:51 < R2COM> but wait
2012-06-07T04:19:54 < R2COM> it doesnt work
2012-06-07T04:21:04 < R2COM> im looking at manual
2012-06-07T04:21:12 < R2COM> well yeah in original gdb manual it says step
2012-06-07T04:21:13 < R2COM> or s
2012-06-07T04:21:18 < R2COM> but
2012-06-07T04:21:35 < karlp> are you running wit -O0?

2012-06-07T04:22:03 < R2COM> one sec
2012-06-07T04:22:13 < karlp> if you have optimizations turned on, then stepping may not produce the results you expect

2012-06-07T04:22:28 < karlp> you can just let it roll, and let gdb take you where it thinks is best

2012-06-07T04:27:17 < R2COM> oh yea... got it... the thing is, this file is INSIDE my project folder, but i was looking at similar file in the ST/STM32fxx/templates/ folder
2012-06-07T04:27:33 < R2COM> i have no idea why on earth this shit exists in several places, and its different
2012-06-07T04:28:14 < dongs> Ya i never use templates. I have the cmsis/stdperiph structure with each project
2012-06-07T04:28:18 < dongs> and I always use #include ""

2012-06-07T04:44:39 < R2COM> i started rewriting stdperiph
2012-06-07T04:44:46 < dongs> silly.
2012-06-07T04:45:24 < R2COM> you kiddin? every time im going to go through each shit function like PeriphClockCmdWhatFuckingEver and so on until i figure out what it does?
2012-06-07T04:45:55 < R2COM> so what i decided to do now is, i traced one thing, for example TIM3 peripheral, and the way how its clock is enabled
2012-06-07T04:46:01 < R2COM> and now, im looking at datasheet
2012-06-07T04:46:10 < R2COM> and want to put my own definitions
2012-06-07T04:46:38 < R2COM> dongs: whats the problem? today at least 3 people already said that stdperiph is crap... so?
2012-06-07T04:46:49 < dongs> those people use lunix and don't value thier time
2012-06-07T04:46:56 < dongs> so I'mn not sure how helpful thier advice is
2012-06-07T04:47:02 < dongs> another guy who said its crap writes code like
2012-06-07T04:47:09 < dongs> BLAH->CR = 0x7a69;
2012-06-07T04:47:28 < dongs> I think I would rather take something like PeriphClockCmdWhatFuckingEver() with some human-readable args
2012-06-07T04:47:32 < R2COM> what you do? autocomplete shit?
2012-06-07T04:47:34 < R2COM> in IDE?
2012-06-07T04:47:54 < dongs> i would if I could. but generally I just have the header files for the stuff im using open
2012-06-07T04:47:57 < dongs> its really not that hard.
2012-06-07T04:48:30 < R2COM> lol then screw that! if one would use autocomplete then its something at least...
2012-06-07T04:48:39 < R2COM> but having header and looking...again waste of time
2012-06-07T04:48:43 < R2COM> what im thinking of, is:
2012-06-07T04:49:00 < R2COM> make several basic easy to memorise functions, and obvious register names, and i just reuse them
2012-06-07T04:49:05 < R2COM> no need to even open anything later
2012-06-07T04:49:27 < dongs> well, theres nothing actually w rong with stdperiph functions
2012-06-07T04:49:27 < R2COM> functions like: regwrite(REGNAME, VALUE)
2012-06-07T04:49:34 < dongs> uh well
2012-06-07T04:49:37 < dongs> regwrite is just
2012-06-07T04:49:40 < dongs> regname->blah??
2012-06-07T04:49:41 < dongs> or wat
2012-06-07T04:49:53 < R2COM> no i write my own function regwrite
2012-06-07T04:49:56 < dongs> why?
2012-06-07T04:50:00 < R2COM> and in my main.c just reuse it
2012-06-07T04:50:03 < R2COM> because...ill tell
2012-06-07T04:50:25 < dongs> http://bcas.tv/paste/results/3d4Z6R25.html what's confusing about shit like this?
2012-06-07T04:50:26 < R2COM> because stdperiph has many different functions for different shit, but honestly they all literally WRITE stuff in regs
2012-06-07T04:50:36 < dongs> also I think I can just combine all same peripheral flags on one line
2012-06-07T04:50:39 < R2COM> ok ill tell
2012-06-07T04:50:41 < R2COM> first of all
2012-06-07T04:50:50 < R2COM> so many words each with big letter
2012-06-07T04:50:57 < R2COM> i mean thats slow
2012-06-07T04:51:18 < R2COM> its just inconvenient
2012-06-07T04:51:26 < R2COM> why to have ClockCmd?
2012-06-07T04:51:30 < R2COM> it write value to regs!
2012-06-07T04:51:30 < dongs> lunix_way_with_underscores_and_shit_is_more_lame()
2012-06-07T04:51:33 < R2COM> just like all other functions
2012-06-07T04:51:55 < R2COM> so, its better just to have regwrite(REG, VAL)
2012-06-07T04:52:01 < R2COM> and then make registers have obvious names
2012-06-07T04:52:05 < dongs> well shit dude, if you dont like long names, you just do RCC->APB1ENR |= 0xwhateverbitmask;
2012-06-07T04:52:12 < dongs> how does that make you better than that other dude
2012-06-07T04:52:28 < dongs> registers DO have obvious names
2012-06-07T04:52:30 < R2COM> well, that works too
2012-06-07T04:52:35 < dongs> and as you noticed they're all in f4xx.h
2012-06-07T04:53:12 < R2COM> RCC_APB2Periph_GPIOB   <---- not nice, this is better ------> PERIPHERAL_APB2GPIOB
2012-06-07T04:53:16 < R2COM> dont you think?
2012-06-07T04:53:17 < dongs> no
2012-06-07T04:53:33 < dongs> style nazism never gets you anywehre with  vendor-provided shit
2012-06-07T04:53:33 < R2COM> first, one less separation, second same capital letters
2012-06-07T04:53:42 < dongs> you;ll be the only kid on teh block rewriting everything and wasting time while others are getting shti done
2012-06-07T04:54:13 < dongs> stdperiph shit has pretty good separation for all peripherals
2012-06-07T04:54:20 < dongs> i.e. if you dont like to use thier _rcc shit just dont use it
2012-06-07T04:54:29 < dongs> but you can stil use timer shit e tc.
2012-06-07T04:54:46 < dongs> but personally i dont think its all that evil
2012-06-07T04:55:15 < dongs> are you saying there's redefinition of RCC_APB2Periph_GPIOA in f4xx.h?
2012-06-07T04:55:25 < R2COM> by the way, yes
2012-06-07T04:55:37 < R2COM> also, those fucking for loops to determine current pin
2012-06-07T04:55:45 < R2COM> which takes my CPU power
2012-06-07T04:55:46 < dongs> i dont see it
2012-06-07T04:55:52 < R2COM> yes today i discussed it
2012-06-07T04:55:58 < dongs> iknow
2012-06-07T04:56:00 < dongs> im scrolling up
2012-06-07T04:56:02 < dongs> i dont see it in my .h
2012-06-07T04:56:06 < dongs> but im loking at f1xx
2012-06-07T04:56:24 < R2COM> http://shorttext.com/8tpQxJ
2012-06-07T04:56:29 < R2COM> look here
2012-06-07T04:56:37 < R2COM> its using for loop, to determine current pin
2012-06-07T04:56:44 < R2COM> GPIO_Init function
2012-06-07T04:57:10 < R2COM> pinpos shit
2012-06-07T04:57:24 < dongs> gpio IS ugly.
2012-06-07T04:57:30 < dongs> i agree with that
2012-06-07T04:57:31 < R2COM> so whatever
2012-06-07T04:57:33 < dongs> other shit is just fluff i think
2012-06-07T04:57:37 < R2COM> ehh
2012-06-07T04:57:39 < R2COM> still
2012-06-07T04:58:03 < dongs> RCC_APB2ENR_IOPAEN
2012-06-07T04:58:04 < dongs> haha
2012-06-07T04:58:09 < dongs> vs RCC_APB2Periph_GPIOA
2012-06-07T04:58:22 < R2COM> no
2012-06-07T04:58:36 < dongs> im saying the cmsis define vs stdlib
2012-06-07T04:58:41 < R2COM> ok
2012-06-07T04:59:04 < dongs> lemme rewritee that block i pasted using raw register shit and see how much it saves
2012-06-07T04:59:07 < dongs> i'd guess not so much
2012-06-07T04:59:27 < R2COM> hmmm so CMSIS and stdperiph has same definitions...? heh...
2012-06-07T04:59:30 < R2COM> i mean
2012-06-07T04:59:35 < R2COM> different definitions but for same stuff
2012-06-07T04:59:54 < dongs> yes..
2012-06-07T05:00:10 < R2COM> slowly slowly i want to transition out of all that crap
2012-06-07T05:05:06 < R2COM> also, redefenition not of GPIOA, but of RCC_APB1 Peripherals, one in stm32f4xx_rcc.h file another in stm32f4xx.h file...
2012-06-07T05:05:10 < dongs> well funny
2012-06-07T05:05:16 < dongs> i found a bug in my code with this
2012-06-07T05:05:24 < dongs> RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA2, ENABLE); i had this
2012-06-07T05:05:27 < dongs> and it was building
2012-06-07T05:05:31 < R2COM> ok?
2012-06-07T05:05:34 < dongs> but apparently there's no DMA2 on F103?
2012-06-07T05:05:42 < dongs> RCC_AHBENR_DMA2EN is not defined
2012-06-07T05:05:42 < R2COM> im not sure about F1
2012-06-07T05:05:45 < dongs> except for CL or HD
2012-06-07T05:05:49 < R2COM> im using F4
2012-06-07T05:11:05 < dongs> well this is weird
2012-06-07T05:12:46 < dongs> http://bcas.tv/paste/results/xFGpYs61.html
2012-06-07T05:13:33 < dongs> but which one is easier to read?
2012-06-07T05:13:53 < R2COM> isnt it same shit
2012-06-07T05:13:58 < dongs> yes it is
2012-06-07T05:14:06 < dongs> but to me the 2nd part is easier to read
2012-06-07T05:14:10 < R2COM> then why you ask which one is easier
2012-06-07T05:14:18 < R2COM> oh
2012-06-07T05:14:19 < R2COM> wait
2012-06-07T05:14:30 < R2COM> no way
2012-06-07T05:14:31 < R2COM> 1st
2012-06-07T05:14:35 < dongs> yes way
2012-06-07T05:14:47 < dongs> notice the RCC_* shit compiles smaller too
2012-06-07T05:14:54 < R2COM> more switching between caps, more errors etc
2012-06-07T05:14:57 < R2COM> typos
2012-06-07T05:15:04 < dongs> I dont type any of that shit
2012-06-07T05:15:24 < R2COM> what you do then?
2012-06-07T05:16:08 < dongs> dunno
2012-06-07T05:16:51 < dongs> im curious how RCC_* shit gets compiled into smaller code
2012-06-07T05:16:57 < dongs> by 4 bytes
2012-06-07T05:17:02 < R2COM> i dont know, there must be something else
2012-06-07T05:17:06 < dongs> nope
2012-06-07T05:17:09 < R2COM> because that shouldnt matter
2012-06-07T05:17:10 < dongs> just switch #if 0 to #if 1
2012-06-07T05:17:27 < dongs> should look at asm
2012-06-07T05:17:28 < dongs> lets see
2012-06-07T05:17:30 < R2COM> RCC->APB1ENR should be fastest
2012-06-07T05:20:54 < dongs> X    ((RCC_TypeDef *) ((((uint32_t)0x40000000) + 0x20000) + 0x1000))->APB1ENR |= (((uint32_t)0x00000001) | ((uint32_t)0x00000002) | ((uint32_t)0x00000004) | ((uint32_t)0x00400000));
2012-06-07T05:21:01 < dongs> this is what prepropcessor turns it into
2012-06-07T05:21:31 < R2COM> it turns to this which piece of code?
2012-06-07T05:21:44 < dongs>     RCC->APB1ENR |= (RCC_APB1ENR_TIM2EN | RCC_APB1ENR_TIM3EN | RCC_APB1ENR_TIM4EN | RCC_APB1ENR_I2C2EN);
2012-06-07T05:22:04 < R2COM> so?
2012-06-07T05:23:39 < dongs> http://bcas.tv/paste/results/J5COln34.html
2012-06-07T05:23:44 < dongs> haha wow it actually DOES end up BL'ing to it
2012-06-07T05:24:16 < dongs> so same size is kinda lucky
2012-06-07T05:24:29 < R2COM> ...and, now what?
2012-06-07T05:24:31 < dongs> i would have expected the shit to get inlined
2012-06-07T05:26:38 -!- izua [~izua@unaffiliated/izua] has quit [Ping timeout: 240 seconds]
2012-06-07T05:29:31 < R2COM> also, if im rewriting stdperiph, i guess there later wouldnt be need to use CMSIS either...
2012-06-07T05:29:31 < R2COM> heh
2012-06-07T05:29:39 < R2COM> of course cant do it all instantly
2012-06-07T05:29:42 < dongs> well, ive got news for you
2012-06-07T05:29:46 < dongs> doing direct register shit
2012-06-07T05:29:48 < R2COM> what left is: linker script, and startup file
2012-06-07T05:29:50 < dongs> results in bigger files
2012-06-07T05:29:57 < dongs> and yes i made sure that function  isnt used anywehre else in code
2012-06-07T05:30:06 < dongs> i took out all reference to RCC_APB1PeriphClockCmd
2012-06-07T05:30:10 < R2COM> ok how does that happen?
2012-06-07T05:30:12 < dongs> and replaced with raw RCC->APB1ENR
2012-06-07T05:30:19 < dongs> and shit is like 12 bytes bigger
2012-06-07T05:30:42 < R2COM> how?
2012-06-07T05:30:46 < R2COM> whats the reason
2012-06-07T05:31:38 < R2COM> because it doesnt make sense...
2012-06-07T05:31:43 < R2COM> there must be some reason
2012-06-07T05:32:04 < dongs> compare asm
2012-06-07T05:32:20 < R2COM> well..it might be due to the fact, that you are still using that stdperiph
2012-06-07T05:32:27 < dongs> no
2012-06-07T05:32:34 < R2COM> but you still using it right?
2012-06-07T05:32:35 < R2COM> you do
2012-06-07T05:32:35 < dongs> unused functions dont get linked..
2012-06-07T05:32:48 < R2COM> no... but APB1ENR *IS* used
2012-06-07T05:32:57 < R2COM> its defined in the structure as:
2012-06-07T05:33:03 < R2COM>   __IO uint32_t APB1ENR;       /*!< RCC APB1 peripheral clock enable register,                   Address offset: 0x40 */
2012-06-07T05:33:20 < R2COM> what is that __IO macro by the way...
2012-06-07T05:33:37 < dongs> just same as volatile
2012-06-07T05:33:43 < R2COM> so, maybe its designed to be used fully with their shit, and once you start modifying their shit it gets bigger
2012-06-07T05:34:01 < R2COM> maybe, if you would completely not use stdperiph, and do it your way, it would be better
2012-06-07T05:34:24 < R2COM> and plus... its structure
2012-06-07T05:34:33 < R2COM> so maybe it reserves somehow more memory
2012-06-07T05:34:35 < dongs> dude
2012-06-07T05:34:35 < R2COM> or...
2012-06-07T05:34:37 < R2COM> i dont know
2012-06-07T05:34:46 < dongs> no.. its memory mapped this is only instruction to compiler
2012-06-07T05:34:54 < dongs>  X    ((RCC_TypeDef *) ((((uint32_t)0x40000000) + 0x20000) + 0x1000))->APB1ENR |= (((uint32_t)0x00000001) | ((uint32_t)0x00000002) | ((uint32_t)0x00000004) | ((uint32_t)0x00400000));
2012-06-07T05:34:58 < dongs> notice this shit
2012-06-07T05:35:02 < R2COM> ok?
2012-06-07T05:35:10 < dongs> it just writes blah to that address
2012-06-07T05:35:30 < dongs> 0x40000000+0x20000+0x1000+offset of apb1enr
2012-06-07T05:35:48 < R2COM> ok
2012-06-07T05:35:50 < dongs> mm my mouser order showed up
2012-06-07T05:35:56 < dongs> time to check out this awesome $50 gps antenna i got
2012-06-07T05:36:04 < dongs> shit better give me a lock indoors
2012-06-07T05:36:38 < R2COM> ok, now you have an idea why it got bigger?
2012-06-07T05:36:43 < R2COM> i mean the real reason
2012-06-07T05:36:49 < R2COM> ?
2012-06-07T05:37:16 < dongs> no i certainly don't. RCC_APB1PeriphClockCmd shouldn't be linked anymore in raw version
2012-06-07T05:37:19 < dongs> let me see the linker/map output
2012-06-07T05:37:40 < dongs> hmm its still used
2012-06-07T05:37:42 < dongs> somewehre
2012-06-07T05:38:20 < dongs> hm or is it
2012-06-07T05:41:34 < dongs> ok right
2012-06-07T05:41:35 < dongs> its not used
2012-06-07T05:41:38 < dongs> so, still, its bigger.
2012-06-07T05:41:59 < R2COM> but its nonsense
2012-06-07T05:42:53 < dongs> 1G/hm its still in global symbols list

2012-06-07T05:49:44 < dongs> holy shit
2012-06-07T05:49:54 < dongs> enabled crossmodule optimization
2012-06-07T05:50:04 < dongs> 43152 -> 38144
2012-06-07T05:54:32 < R2COM> so?
2012-06-07T05:55:38 < R2COM> are you comparing size of .elf file by the way?
2012-06-07T05:55:40 < R2COM> or which one?
2012-06-07T05:55:48 < dongs> no, compiler outputs statistics
2012-06-07T05:55:55 < dongs> Program Size: Code=38144 RO-data=3612 RW-data=968 ZI-data=5608
2012-06-07T05:55:56 < dongs> i.e. like this
2012-06-07T05:57:34 < R2COM> hell i dont know how to get this data with my tools
2012-06-07T05:58:45 < R2COM> ill compare the size of .bin files then
2012-06-07T06:00:53 < dongs> ok gonna rebuild with stdperiph thing and see. crossoptimization probably kills that stuff
2012-06-07T06:01:15 < dongs> Program Size: Code=38204 RO-data=3608 RW-data=968 ZI-data=5608
2012-06-07T06:01:16 < dongs> yeah
2012-06-07T06:01:17 < dongs> ok
2012-06-07T06:01:19 < R2COM> ok i have some results
2012-06-07T06:01:24 < R2COM> here is what i did
2012-06-07T06:01:50 < R2COM> i have this line:  RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);    i compiled it, and size of .bin file was: 7840
2012-06-07T06:02:14 < R2COM> then i changed that line to: RCC->APB1ENR |= RCC_APB1Periph_TIM3;  compiled, and size of .bin file is: 7848
2012-06-07T06:02:16 < R2COM> bytes
2012-06-07T06:02:31 < dongs> so its biggar.
2012-06-07T06:03:09 < R2COM> not sure why
2012-06-07T06:03:11 < R2COM> the thing is
2012-06-07T06:03:25 < R2COM> first line, in its code contains second line
2012-06-07T06:03:30 < R2COM> you see what im saying?
2012-06-07T06:04:57 < R2COM> http://shorttext.com/kxEzN80
2012-06-07T06:05:08 < R2COM> look at that
2012-06-07T06:05:26 < R2COM> the long line, which i changed to a short line....basically that big function
2012-06-07T06:05:40 < R2COM> it contains that short code too, RCC->APB1ENR ...
2012-06-07T06:05:51 < dongs> right.
2012-06-07T06:06:01 < R2COM> its just there is assert_param shit
2012-06-07T06:06:08 < dongs> thats a no-op
2012-06-07T06:06:11 < R2COM> and one comparison (wasting processor time)
2012-06-07T06:06:29 < R2COM> or maybe compiler optimizes that
2012-06-07T06:06:47 < dongs> i can see it optimizing it (maybe) if y ou never disable
2012-06-07T06:07:00 < dongs> i.e. theres only one code path, and thats to enable
2012-06-07T06:07:13 < R2COM> im gona try something else now
2012-06-07T06:07:52 < dongs> after I enabled proper optimizations it actually optimized APB1shit out.
2012-06-07T06:08:34 < dongs> yes, and its gone from linker map
2012-06-07T06:10:36 < R2COM> now which one is smaller?
2012-06-07T06:10:43 < dongs> the raw one
2012-06-07T06:10:53 < dongs> Program Size: Code=38144 RO-data=3612 RW-data=968 ZI-data=5608 vs Program Size: Code=38204 RO-data=3608 RW-data=968 ZI-data=5608
2012-06-07T06:11:05 < dongs> 60 bytes out
2012-06-07T06:14:35 < R2COM> heh
2012-06-07T06:14:38 < R2COM> i did this now:
2012-06-07T06:14:50 < R2COM> uint32_t* regPtr = (uint32_t*)0x40023800;
2012-06-07T06:14:59 < R2COM> *(regPtr) |= RCC_APB1Periph_TIM3;
2012-06-07T06:15:07 < R2COM> and now its even bigger: 7856 bytes
2012-06-07T06:15:21 < R2COM> its address of exactly RCC_APB1ENR register
2012-06-07T06:15:24 < R2COM> precise address
2012-06-07T06:15:28 < dongs> right
2012-06-07T06:15:37 < dongs> why not just
2012-06-07T06:15:48 < dongs> *(uint32_t*)0x40023800 |= RCC_APB1Periph_TIM3 or whatever
2012-06-07T06:16:04 < dongs> also it should be volatile uint32_t
2012-06-07T06:16:22 < R2COM> *(volatile uint32_t*)0x40023800 |= RCC_APB1Periph_TIM3
2012-06-07T06:16:24 < R2COM> like this?
2012-06-07T06:16:47 < dongs> or something yeah
2012-06-07T06:17:18 < R2COM> i tried in similar way
2012-06-07T06:17:48 < R2COM> volatile uint32_t* regPtr = (volatile uint32_t*)0x40023800;
2012-06-07T06:17:56 < R2COM> *(regPtr) |= RCC_APB1Periph_TIM3;
2012-06-07T06:18:01 < R2COM> same ... : 7856
2012-06-07T06:18:03 < dongs> compare asm to see what its really doing
2012-06-07T06:18:06 < dongs> are you building with -O3 or so?
2012-06-07T06:18:08 < dongs> or -Os i guess
2012-06-07T06:18:11 < dongs> for gcc
2012-06-07T06:18:21 < R2COM> OPTLVL:=3 # Optimization level, can be [0, 1, 2, 3, s].
2012-06-07T06:18:28 < dongs> try s
2012-06-07T06:19:00 < R2COM> same shit
2012-06-07T06:19:06 < R2COM> s is highest?
2012-06-07T06:19:11 < dongs> s is optimize for size
2012-06-07T06:21:47 < R2COM> this gave less size:  *(volatile uint32_t *)0x40023800 |= RCC_APB1Periph_TIM3;
2012-06-07T06:21:47 < R2COM> 7848
2012-06-07T06:21:58 < R2COM> but not 7840 as it is with that long stdperiph function
2012-06-07T06:23:30 < R2COM> it has to do i guess with the way how compiler handles function call and direct access

2012-06-07T06:24:23 < R2COM> any more ideas?
2012-06-07T06:25:01 < dongs> is your file just main() { stdperiph; }?
2012-06-07T06:25:05 < dongs> or is there other code
2012-06-07T06:26:43 < R2COM> other code
2012-06-07T06:26:48 < dongs> well
2012-06-07T06:26:55 < dongs> did you check if other code doesnt call that function??
2012-06-07T06:27:14 < R2COM> RCC_APB1PeriphClockCmd  ?
2012-06-07T06:27:37 < dongs> yes
2012-06-07T06:27:46 < dongs> i.e. some other shit inside stdperiph might be calling it.
2012-06-07T06:28:11 < R2COM> i checked in my main.c noone does
2012-06-07T06:28:30 < R2COM> here another thing i did:
2012-06-07T06:28:43 < R2COM> since it handled better a function
2012-06-07T06:28:46 < R2COM> i decided do my own
2012-06-07T06:28:46 < R2COM> void config_rcc_apb1enr(uint32_t arg)
2012-06-07T06:28:47 < R2COM> {
2012-06-07T06:28:47 < R2COM>     RCC->APB1ENR |= arg;
2012-06-07T06:28:47 < R2COM> }
2012-06-07T06:28:51 < R2COM> and then in main.c :
2012-06-07T06:28:58 < R2COM> config_rcc_apb1enr(RCC_APB1Periph_TIM3);
2012-06-07T06:29:03 < R2COM> result is: 7868
2012-06-07T06:29:06 < R2COM> even much bigger
2012-06-07T06:29:08 < R2COM> lol
2012-06-07T06:29:52 < R2COM> maybe someone else here might have idea
2012-06-07T06:29:58 < R2COM> why is that shit doing it
2012-06-07T06:31:03 < R2COM> ..seriously its weird
2012-06-07T06:33:31 < dongs> well, it works with my compiler
2012-06-07T06:33:37 < dongs> and i did see a nice improvement
2012-06-07T06:33:41 < dongs> so I think your gcc is failing something
2012-06-07T06:34:00 < R2COM> which gcc you using?
2012-06-07T06:34:17 < dongs> im not using gcc
2012-06-07T06:34:18 < dongs> im using armcc
2012-06-07T06:34:29 < dongs> same 38k-bulit project by armcc compiles to like 58k by gcc
2012-06-07T06:35:05 < R2COM> oh...maybe i just shouldnt give a shit to all that
2012-06-07T06:35:05 < R2COM> lol
2012-06-07T06:35:15 < R2COM> afterall its C not asm...and of course different compiler will behave differently

2012-06-07T08:39:52 < R2COM> i think im going to stick with stdperiph for now
2012-06-07T08:40:07 < R2COM> i already messed alot today with some custom coding
2012-06-07T08:40:10 < R2COM> and more experiments
2012-06-07T08:40:20 < R2COM> so, it has to be done thoroughly if done..
2012-06-07T08:40:29 < R2COM> but for now
2012-06-07T08:40:29 < R2COM> i guess ill do CMSIS + stdperiph

2012-06-07T14:00:56 < jpa-> if you properly multiply/divide I & D by the timestep, it should not affect
2012-06-07T14:00:59 < Laurenceb> yeah
2012-06-07T14:01:10 < Laurenceb> i use the timestep as part of the terms

2012-06-07T15:16:24 < karlp> or does it have it's own definitions?
2012-06-07T15:17:49 < zyp> no
2012-06-07T15:17:58 < zyp> it's in the *PSR definitions

2012-06-07T15:51:53 < zyp> isn't a 48-bit mac usually a 24-bit OUI and a 24-bit unique ID?
2012-06-07T15:54:29 < karlp> yeah,
2012-06-07T15:55:01 < karlp> I eventually need an 8bit number, and I just used the lowest byte of the ID portion,
2012-06-07T15:55:14 < karlp> and then just kept the full 48 as the device "serial"

2012-06-07T16:38:24 < Laurenceb> wtf
2012-06-07T16:38:47 < Laurenceb> freenode guy died?
2012-06-07T16:38:51 < zyp> http://en.wikipedia.org/wiki/Rob_Levin
2012-06-07T16:38:57 < dongs> Laurenceb: dude welcome to like 2006
2012-06-07T16:39:27 < dongs> he was fucking trailer trash
2012-06-07T16:39:32 < Laurenceb> lol
2012-06-07T16:39:52 < Laurenceb> dongs is universally bad taste
2012-06-07T16:39:58 < zyp> dongs, isn't google and everything on ipv6 now?
2012-06-07T16:39:59 < cjbaird> The guy I knew was an Andrew@uq.edu.au .. Did 3 days of NON STOP EPIC HAXXINGS in the UQ CompSci student labs, finally decided to go home for sleep, went underneath a truck on his pushbike.
2012-06-07T16:40:16 < dongs> zyp: shit like jvnv.net is uaully megafail
2012-06-07T16:40:17 <+Steffanx> AW
2012-06-07T16:40:26 < dongs> hey
2012-06-07T16:40:27 < dongs> it works now
2012-06-07T16:40:37 < dongs> did you fix something?
2012-06-07T16:40:47 < dongs> ya.. ipv66 sites laod now
2012-06-07T16:40:50 < zyp> no, I haven't changed anything
2012-06-07T16:40:50 < dongs> no lag
2012-06-07T16:40:57 < zyp> maybe your isp did
2012-06-07T16:40:59 <+Steffanx> karlp .. maybe it's some power issues. Power it from my laptop and now using another power supply
2012-06-07T16:41:03 <+Steffanx> It seems to work now
2012-06-07T16:41:44 < karlp> oh, no, I meant the modbus devices I working with are for power metering
2012-06-07T16:41:52 <+Steffanx> Oh LOL
2012-06-07T16:41:57 < karlp> glad it helped though :)
2012-06-07T16:42:02 <+Steffanx> But the rpi had some power issues too i think :P
2012-06-07T16:42:02 < zyp> nice coincidence
2012-06-07T16:42:12 <+Steffanx> Have to test a little more
2012-06-07T16:42:49 <+Steffanx> It seems to perform ok-ish with a samba share
2012-06-07T16:43:00 <+Steffanx> Ok-ish for only 100mbit
2012-06-07T16:43:12 < Laurenceb> aiui ehternet can kill it if its cant grab enough current
2012-06-07T16:45:59 < dongs> ugh
2012-06-07T16:46:02 < dongs> this code his hideous
2012-06-07T16:46:35 < dongs> http://bcas.tv/paste/results/nr8Tgc31.html ?????
2012-06-07T16:49:37 <+Steffanx> It's perfect
2012-06-07T16:50:17 < dongs> its indented almost as good as Laurenceb code
2012-06-07T16:50:35 <+Steffanx> Why you don't just return 0 instead of bRetValue ?
2012-06-07T16:50:36 <+Steffanx> or false
2012-06-07T16:52:43 <+dekar> cjbaird, thanks a lot :)
2012-06-07T16:52:55 <+Steffanx> Hey dekar
2012-06-07T16:53:08 <+Steffanx> You script … it fails for me
2012-06-07T16:53:22 <+dekar> how so?
2012-06-07T16:53:39 <+Steffanx> It fails to compile newlib
2012-06-07T16:53:48 <+Steffanx> "../../../../../newlib-1.20.0/libgloss/arm/crt0.S:37: Error: unknown architecture `armv6s-m'"
2012-06-07T16:54:16 <+dekar> Steffanx, did you patch in some changes?
2012-06-07T16:54:18 <+Steffanx> could it be possible it uses the ' wrong' gcc ?
2012-06-07T16:54:27 <+Steffanx> No, i didn't
2012-06-07T16:54:35 <+dekar> oh, do you have any other toolchain in PATH?
2012-06-07T16:54:41 <+Steffanx> I think so
2012-06-07T16:54:53 <+dekar> there was a bug with $PATH, but it has been fixed
2012-06-07T16:55:00 <+Steffanx> Since when?
2012-06-07T16:55:09 <+dekar> umm yesterday I think :)
2012-06-07T16:55:11 < zyp> since yesterday or so?
2012-06-07T16:55:14 <+Steffanx> Ah ok :)
2012-06-07T16:55:18 < dongs> QM1D1C0045_ILLEAGAL_SLAVE_ADDR
2012-06-07T16:55:19 < dongs> haha..
2012-06-07T16:55:22 <+Steffanx> me updates the repo and tries again
2012-06-07T16:56:04 <+Steffanx> Aw.. karlp too bad
2012-06-07T16:56:09 <+Steffanx> You non-help didn't help
2012-06-07T16:56:30 <+Steffanx> It still disconnects
2012-06-07T17:03:34 <+Steffanx> I guess it has some issues with large data streams .. f
2012-06-07T17:11:41 <+Steffanx> hmpf dekar :P
2012-06-07T17:11:50 <+Steffanx> "reverted back to /bin/bash cause using env failed on OSX" 2 minutes ago :P
2012-06-07T17:15:45 <+dekar> Steffanx, I did commit cjbairds version without further checking :/
2012-06-07T17:15:50 <+dekar> shouldn't have done that :P
2012-06-07T17:16:17 <+dekar> check it out again, it should work on OSX now
2012-06-07T17:16:55 < karlp> hehe
2012-06-07T17:16:58 <+Steffanx> btw .. softfp means it won't be able to use hardware fp for m4?
2012-06-07T17:17:09 < karlp> tnt is m3 only and forever :)
2012-06-07T17:17:28 <+dekar> karlp, feel free to supply multilib support
2012-06-07T17:18:51 <+Steffanx> You disappoint me dekar
2012-06-07T17:19:00 <+dekar> Steffanx, how so?
2012-06-07T17:19:25 <+Steffanx> That what i just asked an what you just 'answered' :)
2012-06-07T17:20:04 <+dekar> that's my toolchain and I made it for myself, if you want it to be different, then change it
2012-06-07T17:20:13 <+Steffanx> Too many disappointing moments today.. have to figure out why the rpi drops it's ethernet connection :P
2012-06-07T17:20:17 <+dekar> it's open source after all
2012-06-07T17:20:26 < zippe> All these people suffering… just use the ARM bare-metal toolchain & get on with life 8)
2012-06-07T17:23:39 <+Steffanx> Arh, the crappy open source philosophy all the time.
2012-06-07T17:23:51  * jpa- uses the STeffanx bare-skin toolchain
2012-06-07T17:23:53 < zippe> er, what?
2012-06-07T17:23:54 <+Steffanx> I prefer "when it doesn't work/fit my needs, use something else" :)
2012-06-07T17:24:13 < zippe> Steffanx: the ARM baremetal toolchain is the ARM-maintained snapshots of the GCC-embedded branch
2012-06-07T17:24:25 < zippe> They test it, can a build script and post it to launchpad
2012-06-07T17:24:35 < zippe> They also build and post linnex and windows binaries
2012-06-07T17:25:30 <+Steffanx> Nah, I'm not into compiling stuff myself. When it fails i most of the time have no idea what to do
2012-06-07T17:26:06 < zippe> Steffanx: brew tap MikeSmith/misc && brew install gcc-arm-none-eabi
2012-06-07T17:26:27 < karlp> zippe: that's the one I'm using, but when I installed liboipencm3 into that directory,
2012-06-07T17:26:41 < karlp> and passed -L for it, it started linking in thewrong modules.
2012-06-07T17:26:58 < karlp> apparently you may _not_ pass -L<root of the toolchain>
2012-06-07T17:27:01 < zippe> When you say "into that directory", which directory?
2012-06-07T17:27:14 < zippe> Well, no, -L is for directories containing libraries
2012-06-07T17:27:21 < zippe> You may be confusing it with -isysroot
2012-06-07T17:27:43 < karlp> if I put them in gcc-arm-none-eabi-4_6-2012q1/arm-none-eabi/lib
2012-06-07T17:27:49 < karlp> and pass -Lgcc-arm-none-eabi-4_6-2012q1/arm-none-eabi/lib
2012-06-07T17:27:57 < karlp> then it links with the libc.a in that directorry
2012-06-07T17:28:10 < karlp> instead of autoselecting the libc.a from the armv7-m directory
2012-06-07T17:28:43 < karlp> if I put libopencm3 somewhere else, and use -L/opt/somewhere then it correctly picks the right libc.a from the mcu= and mthumb flags
2012-06-07T17:29:03 < zippe> Yes, that's normal
2012-06-07T17:29:24 < zippe> Don't ever pass any of the compiler's private library directories to -L
2012-06-07T17:29:35 < karlp> ok :)
2012-06-07T17:29:40 < karlp> I didn't know that.
2012-06-07T17:29:42 < zippe> It
2012-06-07T17:29:48 < zippe> It's not a very smrt animal
2012-06-07T17:30:18 < karlp> so, I should experiment with leaving the libopencm libs in the "root" lib directory and _not_ passing that path with -L.
2012-06-07T17:30:36 < karlp> hopefully it should start in the specific armv7-m dir, not find them, and move up and find them in the root lib dir
2012-06-07T17:30:55 < karlp> I will try that in the next hour or two and report back :)
2012-06-07T17:30:58 < zippe> Don't install anything at all into the gcc directory
2012-06-07T17:31:00 < zippe> Nothing
2012-06-07T17:31:06 < zippe> Especially if you're using homebrew
2012-06-07T17:31:12 < zippe> Put libopencm3 somewhere else
2012-06-07T17:31:25 < karlp> is there anywhere it can go that won't require me to add a -L flag?
2012-06-07T17:31:44 < zyp> why do you want to avoid that?
2012-06-07T17:31:56 < karlp> because I want to treat it like a system installed library?
2012-06-07T17:32:09 < karlp> same as libc, libm, and friends
2012-06-07T17:32:23 < karlp> same as I do with any other library I install on my desktop
2012-06-07T17:32:45 < zippe> Try just installing it in /usr/local
2012-06-07T17:33:22 < zippe> That'll be a bit messy if you don't have a package manager to clean it out
2012-06-07T17:34:17 < zippe> Or use the default as "the place" you install everything that's build arm-none-eabi
2012-06-07T17:38:10 <+Steffanx> It seems the fix didn't fix it, mr dekar. It still seems to use the wrong gcc
2012-06-07T17:38:42 <+Steffanx> Or i'm peckbec-ing
2012-06-07T17:43:55 <+dekar> Steffanx, I just realized the version I got from cjbaird reverted the path fix
2012-06-07T17:44:03 <+Steffanx> Haha
2012-06-07T17:44:19 <+dekar> I'll get it working again and do a test build and tell you once I'm done :)
2012-06-07T17:45:13 <+Steffanx> The power of open source :P
2012-06-07T17:46:22 <+dekar> Steffanx, or you can that revision: https://github.com/EliasOenal/TNT/tree/f3d560264e2f9f415d5fa9afc8cf30a458e2fb07
2012-06-07T17:46:38 <+dekar> that was the last one I tested
2012-06-07T17:48:04 <+Steffanx> Nah, i'll try again tomorrow :P
2012-06-07T17:50:43 <+dekar> k
2012-06-07T17:53:51 < Tectu> this is funny...   whenever i make a struct:    struct foo_t *foo;   fill in the members:     foo->x = <something>;   the struct is filled with:    {1024, 8192, 9777, 2048}
2012-06-07T17:53:57 < Tectu> is this some known issue? :D
2012-06-07T17:54:00 < Tectu> i use chibios
2012-06-07T17:54:06 < Tectu> i got that serval times now...
2012-06-07T17:56:40 < karlp> do you mean, x is not what you set it to?
2012-06-07T17:56:47 < Tectu> jep
2012-06-07T17:56:50 < karlp> or were you expecting your struct to be zero filled automatically?
2012-06-07T17:56:50 < Tectu> gdb:   $3 = {x0 = 10241, y0 = 2048, x1 = 10241, y1 = 2048,
2012-06-07T17:56:50 < Tectu>   state = 0x8002801  <incomplete sequence \347>}
2012-06-07T17:56:55 < Tectu> no
2012-06-07T17:57:05 < Tectu> struct does have 4x uint16_t and one uint8_t*
2012-06-07T17:57:10 < Tectu> and i fill in all the values

2012-06-07T17:57:27 < Tectu> x0 = 100, y0 = 100, x1 = 200, y1 = 200 and state gets some pointer
2012-06-07T17:57:31 < Tectu> i also removed the state stuff

2012-06-07T18:01:08 <+Steffanx> When your pointer points to Tectu ?
2012-06-07T18:01:12 <+Steffanx> *where
2012-06-07T18:01:36 < Tectu> Steffanx, which pointer? the uint8_t* structmember?
2012-06-07T18:01:39 < Tectu> i removed that one, same problem
2012-06-07T18:02:02 < Tectu> and inside a function, i have    struct buttonStruct_t *buttonStruct;
2012-06-07T18:02:09 < Tectu> then i go wiht   buttonStruct->x0 = 100;
2012-06-07T18:02:20 < Tectu> but gdb says:    $4 = {x0 = 10241, y0 = 2048, x1 = 10241, y1 = 2048}
2012-06-07T18:02:27 <+Steffanx> Yeah, and that pointer points to what?
2012-06-07T18:02:36 < Tectu> how to find out?

2012-06-07T18:03:20 <+Steffanx> Look at your code :)
2012-06-07T18:03:23 < Tectu> Steffanx,
2012-06-07T18:03:24 < Tectu> (gdb) print buttonStruct
2012-06-07T18:03:24 < Tectu> $5 = (struct buttonStruct_t *) 0xc8
2012-06-07T18:03:27 < Tectu> is this what you mean?
2012-06-07T18:03:44 < Tectu> what are you trying to tell me, Steffanx ? :d
2012-06-07T18:03:53 <+Steffanx> It now looks like you have a struct buttonStruct_t pointer that points to .. nothing
2012-06-07T18:04:02 < zyp> uh, it's a pointer to 0xc8?
2012-06-07T18:04:09 < Tectu> zyp, looks like
2012-06-07T18:04:27 < zyp> well, that's not to ram, at least
2012-06-07T18:04:34 < Tectu> how to fix?
2012-06-07T18:04:48 <+Steffanx> Don't make it a pointer
2012-06-07T18:04:55 <+Steffanx> or make it point to some valid memory
2012-06-07T18:04:57 < Tectu> that line   struct buttonStruct_t *buttonStruct;  is in a function which gets called in a Thread (from chibios)
2012-06-07T18:05:03 < Tectu> Steffanx, use malloc?
2012-06-07T18:05:10 < Tectu> well, this worked on every x86 program i had :d
2012-06-07T18:05:17 < Tectu> i made*
2012-06-07T18:05:48 <+Steffanx> Sure?
2012-06-07T18:05:55 < zyp> you're not initializing it to anything?
2012-06-07T18:05:57 < Tectu> :/
2012-06-07T18:06:01 < zyp> that can't possibly work
2012-06-07T18:06:07 <+Steffanx> It works, but not as expected :P
2012-06-07T18:06:08 < Tectu> i am not sure what i am doing wrong here o0
2012-06-07T18:06:33 < zyp> you make a pointer, without making it point to anything
2012-06-07T18:06:38 < karlp> yeah, what he said.
2012-06-07T18:06:52 < Tectu> aha!
2012-06-07T18:06:58 < Tectu> so we'd need some malloc magic here?
2012-06-07T18:06:59 < zyp> so it points into the flash alias, somewhere in the vector table
2012-06-07T18:07:19 < zyp> the values you print is actually a couple of vector entries pointing to 0x8002801
2012-06-07T18:07:49 < zyp> are you sure you want a pointer at all?
2012-06-07T18:08:29 < Tectu> well, but when i go with     struct buttonStruct_t buttonStruct;    fill in some values, i get 0,0,0,0  everywhere
2012-06-07T18:08:46 < zyp> everywhere how?
2012-06-07T18:08:48 < Tectu> i guess i missunderstand here something
2012-06-07T18:08:56 < Tectu> zyp, every member of the struct
2012-06-07T18:09:01 < Tectu> all four uint16_t
2012-06-07T18:10:34 < Tectu> okay, seriously now
2012-06-07T18:10:37 < Tectu> i want to get a struct
2012-06-07T18:10:41 < Tectu> while runtime
2012-06-07T18:10:55 < Tectu> so   struct foo_t foo;  is correct or not? o0
2012-06-07T18:10:57 < Tectu> i guess not.
2012-06-07T18:12:43 <+Steffanx> Looks correct to me
2012-06-07T18:12:48 < Tectu> okay
2012-06-07T18:13:14 < Tectu> then i fill in member values like    foo.x0 = 100; foo.y0 = 100; foo.x1 = 200; foo.y1 = 200;
2012-06-07T18:13:15 < Tectu> right?
2012-06-07T18:13:23 <+Steffanx> Yes
2012-06-07T18:13:39 < jpa-> Tectu: it is ok for the current scope
2012-06-07T18:13:55 < jpa-> {struct foo_t foo; return &foo;}  is not ok
2012-06-07T18:14:04 < Tectu> okya, so i did exactly that.... now gdb says:    $10 = {x0 = 0, y0 = 0, x1 = 200, y1 = 200}
2012-06-07T18:14:07 < Tectu> what the hell is wrong?
2012-06-07T18:14:26 < Tectu> i am inside the same scope
2012-06-07T18:14:36 < Tectu> made some breakpoint after filling the struct with the thing above
2012-06-07T18:14:50 < jpa-> optimization or something could be messing up your gdb :P
2012-06-07T18:15:21 < Tectu> jpa-, but about the scope:    when i did wha ti wrote above, i can pass &foo as an argument to a thread or not?
2012-06-07T18:15:38 < jpa-> only if the thread exits before you go out of scope
2012-06-07T18:16:13 < Tectu> well, after filling that struct i go with:     tp = chThdCreateFromHeap(NULL, THD_WA_SIZE(128), NORMALPRIO+1, buttonThread, &buttonStruct);
2012-06-07T18:16:22 < Tectu> and then my function returns
2012-06-07T18:16:28 < Tectu> so that should be okay?
2012-06-07T18:17:00 < jpa-> not really
2012-06-07T18:17:29 < Tectu> how to fix?   though i can go with   struct foo *foo;   and pass   foo as argument
2012-06-07T18:17:47 < jpa-> you could allocate buttonStruct statically
2012-06-07T18:18:08 < jpa-> or malloc (or chCoreAlloc) it
2012-06-07T18:18:12 < Tectu> with   chHeapAlloc()  ?
2012-06-07T18:18:15 < Tectu> ah, not Heap?
2012-06-07T18:18:19 < jpa-> sure, why not
2012-06-07T18:18:23 < Tectu> i am never sure about taking  HeapAlloc or CoreAlloc
2012-06-07T18:18:29 < jpa-> depends on if you want to free it also
2012-06-07T18:18:48 < jpa-> CoreAlloc is one-way only, you can allocate stuff but you can never free it again
2012-06-07T18:19:03 < Tectu> when i use  chHeapAlloc() nside a thread, it takes the memory from the    static WORKING_AREA(foo, 128);  <--- 128 bytes, right?
2012-06-07T18:19:03 <+Steffanx> Never free it :)
2012-06-07T18:19:12 < jpa-> Tectu: no
2012-06-07T18:19:21 < jpa-> working area is just for stack etc.
2012-06-07T18:19:32 < Tectu> heap is "global", right?
2012-06-07T18:19:36 < jpa-> yep
2012-06-07T18:19:39 < Tectu> so not every thread does have it's own?
2012-06-07T18:19:46 < Tectu> what's the core memory then?
2012-06-07T18:19:51 < Tectu> and why can't i free it again?
2012-06-07T18:20:23 < jpa-> because there is no CoreFree :)
2012-06-07T18:20:36 < Tectu> but what/where eactly is the core memory
2012-06-07T18:20:47 < jpa-> core & heap memory reside in the end of ram, it depends on linker script

2012-06-07T18:20:55 < jpa-> by default core & heap use the same memory area
2012-06-07T18:21:51 < jpa-> (CoreAlloc is very simple compared to HeapAlloc; in many embedded systems, you don't need to free the memory so the simpler function is enough)
2012-06-07T18:22:21 < Tectu> so i'd do here:
2012-06-07T18:22:22 < jpa-> (if the program never terminates and it keeps using the memory, why free it)
2012-06-07T18:22:29 < Tectu> struct buttonStruct_t *buttonStruct;

2012-06-07T18:23:29 < Tectu> jpa-, i don't like typedef somehow
2012-06-07T18:23:35 < Tectu> struct is such a small word
2012-06-07T18:23:40 < Tectu> and it looks strange otherwise

2012-06-07T18:24:37 < jpa-> well if the compiler accepts it, you don't need to cast
2012-06-07T18:24:57 < jpa-> you only need a cast in there in C++ code, but in C++ code you should just use 'new' anyway

2012-06-07T18:30:33 < zyp> it doesn't suck

2012-06-07T18:32:53 < zyp> and that's why there is no memory gdb can read to determine the value of that variable

2012-06-07T18:43:43 < R2COM> i cant find it in gdb manual
2012-06-07T18:43:49 < zyp> because you are not debugging source code, you're debugging compiled code, compilet with optimizations
2012-06-07T18:43:55 < zyp> -O0 is a gcc option
2012-06-07T18:44:01 < zyp> to compile without optimizations
2012-06-07T18:44:01 < R2COM> oh
2012-06-07T18:44:34 < R2COM> in makefile i have: OPTLVL:=3 # Optimization level, can be [0, 1, 2, 3, s].
2012-06-07T18:44:37 < R2COM> will see now
2012-06-07T18:45:09 < zyp> optimizations basically steps on your program, crushes it, stirs a bit and packs it together, so it will perform the same task in a faster way
2012-06-07T18:45:17 < R2COM> so, for this arm development in stm32, its better then to do the whole project with -O0? and then if it works, and verified, recompile under -O3?
2012-06-07T18:45:21 < zyp> so the output can be fairly different from the source
2012-06-07T18:46:05 < zyp> «better» is always subject to opinions
2012-06-07T18:47:07 < dongs> zyp, I enabled cross-module optimization in my commercial compiler and my shit went from 43k to 38k compiled.
2012-06-07T18:47:20 < dongs> its sad gcc has nothign equivalent
2012-06-07T18:47:26 < dongs> gcc still builds my code to something like 52k
2012-06-07T18:47:29 < dongs> with -Os
2012-06-07T18:47:29 < karlp> clang does.
2012-06-07T18:47:32 < dongs> terrible
2012-06-07T18:47:50 < zyp> dongs, sure it has
2012-06-07T18:48:01 < karlp> I was reading about whole project opts recently with gcc too I thought
2012-06-07T18:48:26 < zyp> it's called «link time optimization»
2012-06-07T18:49:25 < zyp> but you obviously don't get that when you compile all objects seperate and link them together in the end, like «everyone» does
2012-06-07T18:49:30 < Laurenceb> with usb OTG, should you have a FET to connect the shield to gnd?
2012-06-07T18:49:41 < zyp> Laurenceb, why?
2012-06-07T18:49:45 < dongs> zyp: well, i can do that with my compiler.
2012-06-07T18:49:48 < dongs> k time to passout
2012-06-07T18:49:50 < Laurenceb> to meet USB spec
2012-06-07T18:50:10 < zyp> Laurenceb, using a FET for that sounds like something only you could come up with
2012-06-07T18:50:15 < Laurenceb> lol
2012-06-07T18:50:36 < R2COM> zyp: yesterday we were looking at how setting registers yourself vs using the stdperiph function makes difference on compiled program size, for example if i use standard function: RCC_APB1PeriphClockCmd(RCC_APB1Periph_TIM3, ENABLE);   then my program was 7840 bytes, but when i did this: RCC->APB1ENR |= RCC_APB1Periph_TIM3;  then a program size was 7848 bytes! that doesnt make much sense because RCC_APB1PeriphClockCmd function inside it
2012-06-07T18:51:33 < zyp> R2COM, makes sense to me
2012-06-07T18:51:37 <+dekar> R2COM, did you encapsulate "RCC->APB1ENR |= RCC_APB1Periph_TIM3;" in a function?
2012-06-07T18:51:49 <+dekar> if you didn't then it gets "inlined" all the time
2012-06-07T18:52:03 < R2COM> when it was in standard stdperiph function, and i called that function then it was smaller size
2012-06-07T18:52:16 < R2COM> when i did it by itself in a code it was of a bigger size
2012-06-07T18:52:18 < R2COM> after that
2012-06-07T18:52:32 < R2COM> i did this, i encapsulated it in my own function, and the size was even bigger
2012-06-07T18:52:48 < R2COM> own function was just like stdperiph function except no comparison and assertions in it
2012-06-07T18:53:03 < zyp> R2COM, calling a function is shorter than performing a read-modify-write
2012-06-07T18:53:18 < R2COM> ok, but i did that too
2012-06-07T18:53:24 < R2COM> as i said, size was even bigger
2012-06-07T18:53:25 < jpa-> R2COM: you probably got *both* the stdperiph function and your own function
2012-06-07T18:53:37 < jpa-> if you explicitly didn't leave out the stdperiph library
2012-06-07T18:53:46 < zyp> the read-modify-write needs at least five instructions, calling an already defined function with two arguments needs maybe three
2012-06-07T18:53:51 < R2COM> stdperiph was there, but that function was commented out
2012-06-07T18:54:25 < zyp> R2COM, but what are you concerned about? code size or code speed?
2012-06-07T18:54:28 < jpa-> then check the assembler listing for the differences
2012-06-07T18:54:38 <+dekar> R2COM, just enable proper optimizations, commenting it out shouldn't change the size if it wasn't used
2012-06-07T18:54:40 < R2COM> speed, but i was just curious
2012-06-07T18:54:51 <+dekar> you probably want gc-sections for example
2012-06-07T18:54:58 < R2COM> ok
2012-06-07T18:55:02 < zyp> calling functions is smaller than inlining functions, inlining is larger but faster
2012-06-07T18:55:29 < R2COM> so this gets inlined:  RCC->APB1ENR |= RCC_APB1Periph_TIM3   ?
2012-06-07T18:55:48 < zyp> well, it's not a function
2012-06-07T18:55:49 < R2COM> and supposed to be faster?
2012-06-07T18:55:53 < R2COM> i know
2012-06-07T18:55:57 < zyp> but yes, it's faster
2012-06-07T18:56:04 <+dekar> zyp, I wonder if GCC has an option to "de-duplicate" code fragments
2012-06-07T18:56:18 < zyp> haven't seen one
2012-06-07T18:56:38 < R2COM> so by doing this: RCC->APB1ENR |= RCC_APB1Periph_TIM3 im talking to memory directly, and thats faster than calling function?
2012-06-07T18:57:00 < R2COM> which is being called...and does same thing again
2012-06-07T18:57:04 < zyp> R2COM, yes, because calling the function would do the same, in addition to the function call and function return
2012-06-07T18:57:18 < zyp> calls and returns also consume cpu cycles
2012-06-07T18:57:31 < R2COM> yes
2012-06-07T18:57:44 < R2COM> how did you organize such stuff in your library?

2012-06-07T18:58:13 < R2COM> so its going to be same speed as just doing this: RCC->APB1ENR |= RCC_APB1Periph_TIM3 ?
2012-06-07T18:58:29 < zyp> my code compiles to exactly that

2012-06-07T18:58:51 < R2COM> so inlining function, or writing that code is same thing then
2012-06-07T18:59:14 < zyp> yes, but I only have to write RCC.enable(RCC.TIM3); to get that result ;)
2012-06-07T19:00:19 < R2COM> what i was thinking of, is that when i'll rewrite that library later myself, i'll have few main functions, and one of the main function like regwrite(REG,VAL) and with that stuff i'd operate on any register, how is that idea?
2012-06-07T19:00:20 < zyp> I've considered extending it so I can drop the second RCC part and only write RCC.enable(TIM3);
2012-06-07T19:00:27 < R2COM> instead of bunch of functions like enable() etc...
2012-06-07T19:00:48 < zyp> well, my first impression is that it sounds stupid
2012-06-07T19:00:53 < R2COM> why
2012-06-07T19:01:21 < zyp> because it's kind of the opposite of making an abstraction
2012-06-07T19:01:22 < jpa-> because RCC.enable(RCC.TIM3) probably also selects the right register to write to :)

2012-06-07T19:06:32 < zyp> as long as the bus speeds are hardcoded in the setup, it's fine if it's hardcoded there as well :p

2012-06-07T19:08:44 < jpa-> R2COM: how do you know whether to type RCC_APB1ENR.enable(TIM3); or RCC_APB2ENR.enable(TIM3);?
2012-06-07T19:08:54 < zyp> R2COM, what if I want to enable TIM8 clock then? can you tell me which bus it's on without looking it up?
2012-06-07T19:09:51 < R2COM> well... but the one who builds embedded system supposed at least to know hardware or look in datasheet, if no then wtf
2012-06-07T19:10:05 < zyp> why?
2012-06-07T19:10:17 < R2COM> because he designs low level software for specific chip?
2012-06-07T19:10:37 < R2COM> then whats your suggestion for a better convention?
2012-06-07T19:10:44 < zyp> I know there is a TIM8 on some bus in the device, I want to turn it on, why do I need to check which bus it is on?
2012-06-07T19:10:51 < jpa-> R2COM: so why not write just *(uint32_t*)0x40200324 = 0x02000;?
2012-06-07T19:11:10 < zyp> R2COM, I've already said it
2012-06-07T19:11:26 < zyp> with my library I can write RCC.enable(RCC.TIM8);
2012-06-07T19:11:32 < R2COM> RCC.enable(TIM3);  ?
2012-06-07T19:11:34 < zyp> and then the compiler will resolve the rest for me
2012-06-07T19:11:45 < karlp> classy ;)
2012-06-07T19:11:53 < karlp> function overloading ftmfw
2012-06-07T19:12:00 < R2COM> then, in that case how would it know if its APB1 or APB2?
2012-06-07T19:12:11 < karlp> did you _look_ at the code he posted?
2012-06-07T19:12:23 < karlp> or are you still just on this wild MUST OPTIMIZE ALLLLL THE THINGS! trip
2012-06-07T19:12:37 < zyp> R2COM, http://cgit.jvnv.net/suzumebachi/tree/main.cpp#n83 <- here's my main() functions that uses that function
2012-06-07T19:12:59 < R2COM> looking
2012-06-07T19:13:04 < zyp> http://cgit.jvnv.net/suzumebachi/tree/hal/rcc.h?h=stm32f4 <- and here's the actual implementation
2012-06-07T19:13:13 < jpa-> fancy C++ overloading :)
2012-06-07T19:13:28 < jpa-> but wouldn't be too difficult to do with C either
2012-06-07T19:13:53 < R2COM> ok so function itself figures out
2012-06-07T19:13:56 < R2COM> agree then
2012-06-07T19:14:05 < R2COM> you do TIM8 and it worts things out
2012-06-07T19:15:18 < R2COM> and i guess no trade off for performance
2012-06-07T19:15:26 < R2COM> because decisions are #defines
2012-06-07T19:15:33 < zyp> of course not, it's all compile time
2012-06-07T19:16:03 < zyp> I prefer compiler tricks over preprocessor tricks :)
2012-06-07T19:16:24 < R2COM> you use #defines
2012-06-07T19:16:52 < zyp> only for selecting between stm32f1 and stm32f4
2012-06-07T19:17:04 < R2COM> and then enum

2012-06-07T19:18:14 < R2COM> by the way, you use all the time volatile?  do you use volatile const sometimes?
2012-06-07T19:18:21 < R2COM> to define read only stuff?
2012-06-07T19:18:48 < zyp> nah, I don't really see a point in that
2012-06-07T19:19:01 < R2COM> yeah, me too, i just noticed it in stdperiph
2012-06-07T19:19:13 < zyp> quite a few registers have some bits that are read-write and some that are read-only

2012-06-07T19:19:59 < R2COM> zyp: and i forgot, you use stlink stuff? for debug and program? i mean stlink-texane?
2012-06-07T19:20:13 < zyp> I did
2012-06-07T19:20:26 < R2COM> what soft do you use now for debugging?
2012-06-07T19:20:32 < zyp> blackmagic
2012-06-07T19:20:34 < R2COM> and downloading program
2012-06-07T19:20:36 < R2COM> oh
2012-06-07T19:20:41 < R2COM> that 6-$ thingy?
2012-06-07T19:20:44 < R2COM> 60
2012-06-07T19:20:50 < zyp> sounds about right
2012-06-07T19:21:09 < R2COM> j-link 300$ for commercial
2012-06-07T19:21:10 <+Steffanx> its great :)
2012-06-07T19:21:16 <+Steffanx> the blackmagic
2012-06-07T19:21:52 < R2COM> but, what i dont get is... thats a hardware and maybe plus their software... but why to get another hardware, if you have, say stm32f4discovery?
2012-06-07T19:22:05 < R2COM> if you have that board, then all you need is software for fast debug/download?
2012-06-07T19:22:10 < R2COM> or, whats the point here?
2012-06-07T19:22:47 < R2COM> basically, why to buy another programmer, if you have discovery board?
2012-06-07T19:22:58 < R2COM> which is st-link/v2
2012-06-07T19:22:59 < R2COM> ?
2012-06-07T19:23:33 < zyp> the discovery board is rather unwieldy as a programmer for other boards
2012-06-07T19:23:44 < zyp> http://bin.jvnv.net/f/9kGPA.JPG <- it works, but it's not pretty
2012-06-07T19:23:50 < R2COM> what you mean unwieldy?
2012-06-07T19:23:51 < R2COM> oh
2012-06-07T19:23:57 < R2COM> just not pretty
2012-06-07T19:24:35 < R2COM> so, when you had that board as programmer, you used texane soft?
2012-06-07T19:24:40 < zyp> yes
2012-06-07T19:24:51 < R2COM> its ok, but i still dont undertand why it writes so slow
2012-06-07T19:24:55 < R2COM> 233bytes/sec
2012-06-07T19:24:59 < karlp> because you'ðre using an f4
2012-06-07T19:25:04 < R2COM> yes i do
2012-06-07T19:25:09 < karlp> and you haven't contributed or ported an sram based loaded to texane stlink yet
2012-06-07T19:25:27 < R2COM> like.. what you mean?
2012-06-07T19:25:29 < zyp> http://bin.jvnv.net/f/UGyVL.JPG <- only pic I have of the blackmagic, you can see it if you look closely :p
2012-06-07T19:26:19 < zyp> hanging the discovery board like that in addition to some ghetto wires is not very practical :p
2012-06-07T19:26:55 < R2COM> by the way, how much you payed for that reflow, was it like 300$?
2012-06-07T19:27:05 < jpa-> i like boxed programmers, like pickit2 is :P
2012-06-07T19:27:08 < zyp> probably
2012-06-07T19:27:21 < zyp> jpa-, I've been thinking about shrink-wrapping the blackmagic
2012-06-07T19:27:44 < karlp> you can buy the stlink2 in a box if you like too
2012-06-07T19:27:47 < zyp> but I currently don't have large enough shrink-wrap
2012-06-07T19:27:51 < R2COM> karlp: could you tell me more about what you mean by ported an sram based loaded to texane?
2012-06-07T19:28:15 < karlp> to get fast flashing, you need to load a helper program into the sram of the target, and use that to write fast
2012-06-07T19:28:21 < karlp> the current code has that for f1 and l1
2012-06-07T19:28:24 < karlp> but not for f4
2012-06-07T19:28:30 < R2COM> oh got it
2012-06-07T19:28:34 < karlp> so it has to write them all via separate usb calls
2012-06-07T19:28:38 < karlp> which is slow.
2012-06-07T19:28:47 < karlp> but easy to understand, easy to test and easy to get working.
2012-06-07T19:28:54 < R2COM> but im not ready yet to contribute with that, i'd have to study whole thing, im literally starting only with stm32
2012-06-07T19:29:23 < karlp> so, as has been said, if you want speed, pay money for different tools, or fix it yourself.
2012-06-07T19:29:35 < zyp> or use openocd
2012-06-07T19:29:44 < karlp> or that
2012-06-07T19:29:51 < zyp> if you get it to work :)
2012-06-07T19:29:57 < karlp> I stopped trying
2012-06-07T19:30:08 < zyp> I got flashing to work, but not debugging
2012-06-07T19:30:10 < karlp> it flash really fast, but no gdb  with the arm from launchpad
2012-06-07T19:30:11 < karlp> yeah
2012-06-07T19:30:11 < R2COM> recently one guy reported me he got it working
2012-06-07T19:30:12 < R2COM> but
2012-06-07T19:30:19 < R2COM> getting there now...would take more time
2012-06-07T19:30:22 < R2COM> with openocd
2012-06-07T19:30:32 < R2COM> oh
2012-06-07T19:30:33 < R2COM> ok
2012-06-07T19:30:38 < karlp> I'd rather have gdb than fast flashing personally
2012-06-07T19:30:44 < R2COM> yes sure
2012-06-07T19:31:16 < karlp> you can contribute your hours to either texane/stlink or openocd, to fix either the speed or the gdb support :)
2012-06-07T19:31:30 < R2COM> karlp: you have that code, which does fast flashing, for f1?
2012-06-07T19:31:40 < karlp> it's built into stlink
2012-06-07T19:31:47 < karlp> though openocd's version is even faster
2012-06-07T19:31:57 < R2COM> into...the stm32f103 which is on the discovery board?
2012-06-07T19:32:09 < karlp> into the stm32f100 (valueline)
2012-06-07T19:32:12 < karlp> no,
2012-06-07T19:32:16 < karlp> into the texane/stlink code
2012-06-07T19:32:20 < karlp> if that's what you mean?
2012-06-07T19:32:29 < R2COM> well, can i take a look at it?
2012-06-07T19:32:43 < karlp> sure, you hve the source in front of you,
2012-06-07T19:32:49 < karlp> there's no binary builds of texane/stlink
2012-06-07T19:32:59 < R2COM> is it main.c in flash folder?
2012-06-07T19:33:07 < zyp> R2COM, http://blackmagicdebug.git.sourceforge.net/git/gitweb.cgi?p=blackmagicdebug/blackmagicdebug;a=tree;f=flashstub <- here is the ones blackmagic is using
2012-06-07T19:33:17 < karlp> it's probably in st-common.c
2012-06-07T19:33:20 < zyp> stlink is probably pretty similar
2012-06-07T19:33:24 < karlp> openocd has them in the "contrib" folder
2012-06-07T19:33:35 < karlp> there's are even cooler, using sram fifos, not fixed chunked buffers
2012-06-07T19:33:46 < R2COM> src/stlink-common.c ?
2012-06-07T19:35:50 -!- Randomskk [~adam@paladin.randomskk.net] has quit [Quit: leaving]
2012-06-07T19:37:08 < R2COM> i see that file has functions like: int stlink_fwrite_flash
2012-06-07T19:37:26 < R2COM> so, probably that file is the one you are talking about, which writes fast for f1 but not f4.. ?
2012-06-07T19:37:49 < karlp> are you really seriously going to go and implement this now?
2012-06-07T19:38:04 < R2COM> no, but im curious to see
2012-06-07T19:38:16 < R2COM> i couldnt do it now, i said im barely starting stm32
2012-06-07T19:39:52 < zyp> so, why aren't there a flashing stub for F4? can't be that hard to write if you have the F1 one as a reference
2012-06-07T19:40:01 < karlp> because it hasn't been done :)
2012-06-07T19:40:08 < zyp> maybe I should waste my afternoon on that :p
2012-06-07T19:40:13 < emeb> +1
2012-06-07T19:40:13 < karlp> I don't use the F4, texane doesn't seem to be very active
2012-06-07T19:40:25 < karlp> the people using f4's haven't done it.
2012-06-07T19:40:31 < karlp> I kinda thought uwe might,
2012-06-07T19:40:38 < karlp> but looks like he went down to f0, not f4
2012-06-07T19:42:30 < zyp> ah, the ones in stlink are grabbed from some openocd version
2012-06-07T19:42:38 < karlp> from an old old openocd version
2012-06-07T19:42:47 < karlp> the newer ones are quite different
2012-06-07T19:42:47 < zyp> figured as much
2012-06-07T19:43:33 < karlp> also, I'm not entirely sure how the gpl on ooocd really applies to the bootstubs, as far as bringing them into texane
2012-06-07T19:44:57 < zyp> it's ~20 instructions, can't be that hard to write from scratch :p
2012-06-07T19:45:07 < karlp> for anyone who wants it :)
2012-06-07T19:45:39 < karlp> I'll even snail mail a cookie to someone to sweeten the deal
2012-06-07T19:46:02 < zyp> hmm, do you happen to know where stlink chooses which mcu specific functions to use?
2012-06-07T19:46:24 < karlp> in that giant butt ugly function, that uses a weird mismatch of core id and chip id.
2012-06-07T19:46:39 < karlp> you should be able to rely on sl->chipid being set,
2012-06-07T19:46:52 < karlp> but that first flash_write() function predated multiple target support
2012-06-07T19:47:04 < karlp> so it got some fairly ugly hacks and giant if/else clauses added to it
2012-06-07T19:47:46 < zyp> ah, yeah
2012-06-07T19:48:03 < karlp> man, I got all of modbus working yesterday, and I've spent most of tday wranglig just 96 damn bits.

2012-06-07T19:48:26 < karlp> principle of least surpise on whicih bits should be in which byte positions and endianess is a bit arbitrary.
2012-06-07T19:49:36 < zyp> :p
2012-06-07T19:50:17 < zyp> just make up some weird hashing function
2012-06-07T19:51:34 < zyp> for byte in bytes: id = (id << 1 || id >> 7) + unique_id[i]
2012-06-07T19:51:38 < zyp> or something like that :p
2012-06-07T19:52:15 < karlp> oh, I was going to just use one of the bytes as is, just trying to decide where to start
2012-06-07T19:52:46 < karlp> just my own thickness about how u32 is stored in memory vs u8s, and msb vs lsb
2012-06-07T19:53:13 < zyp> somebody commented that some of the bits were x and y position on wafer, and then wafer serial
2012-06-07T19:53:21 < karlp> if I have 96bits in a u8[], should b96 be in arr[0] or arr[11]? that sort of thing
2012-06-07T19:53:30 < karlp> yeah, that's what I was trying to find out,
2012-06-07T19:53:43 < karlp> there's 16 bits that they say are "also for a future purpose"
2012-06-07T19:54:48 < karlp> or I just hash like it like you've been telling me all day, and to hell with trying to make the modbus slave id be easily humanly determined from the serial number
2012-06-07T19:58:48 < zyp> read it out when you program the chip and put a sticker on it ;)
2012-06-07T20:01:53 < zyp> hmm, indentation of stlink code is horrible
2012-06-07T20:02:03 < zyp> some nasty mix of tabs and spaces
2012-06-07T20:03:21 < zyp> setting editor to 4 spaces per tab seems to do the trick
2012-06-07T20:04:38 < zyp> almost
2012-06-07T20:04:57 < zyp> this must be a mix of people with a lot of different editor settings
2012-06-07T20:07:10 < karlp> indeed
2012-06-07T20:07:23 < karlp> and it all being slammed in, without any massaging
2012-06-07T20:07:31 < zyp> yeah
2012-06-07T20:07:59 < zyp> almost tempted to reindent it before starting, but that would be kind of intrusive :p
2012-06-07T20:08:03 < karlp> a long time ago I had netbeans reformat large chunks of it, but that time is long past
2012-06-07T20:08:12 < karlp> do it anyway :)
2012-06-07T20:08:20 < karlp> it's no more intrusive than say, autotools
2012-06-07T20:09:03 < zyp> meh, I'm not sure I got a tool fixing shit like that
2012-06-07T20:10:23 < zyp> personally I prefer single tab as indentation character, because then people don't have to agree about indentation width
2012-06-07T20:12:23 < zyp> to me, that seems like a much more reasonable compromise than forcing one indentation width on everyone
2012-06-07T20:33:15 < karlp> I'm a spaces not tabs person :)
2012-06-07T20:33:40 < karlp> too many things get mangled in transport when it matters what _sort_ of whitespace to use

2012-06-07T21:04:12 <+Steffanx> No, I received my board from nxp a while ago
2012-06-07T21:04:18 < R2COM> so that f0 is downgraded f4?
2012-06-07T21:04:18 <+Steffanx> Actually a few months

2012-06-07T22:11:27 < karlp> the -march=armv7 was wrong.
2012-06-07T22:11:40 < karlp> changing it to -mcpu=cortex-m3 like in the cflags fixes everything

2012-06-07T22:27:26 < karlp> :)
2012-06-07T22:27:34 < karlp> me too!
2012-06-07T22:27:39 < R2COM> in the stm32 manual fPCLK refered to which clock?
2012-06-07T22:27:40 < karlp> I fixed my own linker errors!
2012-06-07T22:27:47 < karlp> the world improves, one day at at ime
2012-06-07T22:28:14 <+Steffann> No
2012-06-07T22:28:33 <+Steffann> Today only bugs for me
2012-06-07T22:28:39 < R2COM> fPCLK is the prescaler output clock?
2012-06-07T22:28:47 < R2COM> or main system one which is usually 168MHz?
2012-06-07T22:31:06 < R2COM> letter P should stand for prescaler..
2012-06-07T22:31:19 < R2COM> in the manual they refer to it a lot, but never state where that shit come from
2012-06-07T22:31:30 < zyp> check the clock diagram in the clock chapter
2012-06-07T22:32:59 < R2COM> i see page 85
2012-06-07T22:33:07 < R2COM> FCLK coming out of prescaler AHB
2012-06-07T22:33:33 < R2COM> but not fPCLK
2012-06-07T22:34:37 < R2COM> SYSLCLK is before prescaler
2012-06-07T22:34:39 < R2COM> FCLK is after
2012-06-07T22:34:48 < R2COM> and in datasheet theres lots of fPCLK
2012-06-07T22:34:57 < R2COM> maybe its just an error, and they mean FCLK by writing that
2012-06-07T22:44:01 < zyp> karlp, ok, now I'm stuck :p
2012-06-07T22:44:44 < zyp> nothing happens after starting the flash loader
2012-06-07T22:45:14 < zyp> is_core_halted() never returns true, so it just «runs» until timeout
2012-06-07T22:45:24 < zyp> inspecting pc, it seems like it doesn't even start
2012-06-07T23:01:01 < Tectu> jpa-, arround?
2012-06-07T23:01:14 < Tectu> well, jpa- and everyone else:   http://forum.chibios.org/phpbb/viewtopic.php?f=2&t=458&p=4098#p4098
2012-06-07T23:05:56 < zyp> oh, think I got it
2012-06-07T23:06:24 < zyp> Tectu, were you one of the guys having problems with the ram-only examples distributed with texane?
2012-06-07T23:06:32 < karlp> almost everyone.
2012-06-07T23:06:39 < karlp> there's bad dodgy stack stuff there
2012-06-07T23:06:52 < karlp> it would work if a _prior_ app ha dset up proper stack and vector stuff
2012-06-07T23:07:07 < karlp> zyp: I don't really know too much about the way the sram loaders are started,
2012-06-07T23:07:12 < karlp> I think uwe wrote that.
2012-06-07T23:07:14 < Tectu> zyp, yeah
2012-06-07T23:07:31 < zyp> I suspect that _stlink_usb_run is broken
2012-06-07T23:07:43 < karlp> is that used anywhere else?
2012-06-07T23:07:46 < zyp> and that's why it won't execute my flash stub
2012-06-07T23:08:03 < karlp> there's probably still some dead routines that aren't used anywhere, and so might not actually do the right thing
2012-06-07T23:08:33 < zyp> I made a loop doing single-stepping instead, looks like it made my flash loader work
2012-06-07T23:10:59 < zyp> hmm, or not
2012-06-07T23:15:35 < karlp> sorry, cooking dinner, don't have the stlink code in front of me right now

2012-06-07T23:46:42 < R2COM> SPI_CR1_CPHA | SPI_CR1_LSBFIRST | SPI_CR1_MSTR | SPI_CR1_SPE);
2012-06-07T23:46:50 < R2COM> before that CR register is 0
2012-06-07T23:46:54 < R2COM> but after that its still 0
2012-06-07T23:47:05 < R2COM> oh
2012-06-07T23:47:09 < R2COM> nevermind
2012-06-07T23:47:14 <+Steffann> :)
2012-06-07T23:47:27 < zyp> oh, I got it working
2012-06-07T23:47:37 < R2COM> zyp, it writes FAST?
2012-06-07T23:47:48 < zyp> don't know that yet
2012-06-07T23:47:54 < R2COM> maybe i try?
2012-06-07T23:47:59 < R2COM> i have the f4 board
2012-06-07T23:48:04 < karlp> slow down R2COM
2012-06-07T23:48:08 < karlp> you can't optimize the world
2012-06-07T23:48:11 < zyp> I haven't done any block-splitting yet, so it can't flash anything larger than ram
2012-06-07T23:48:18 < R2COM> ok
2012-06-07T23:48:21 < zyp> and it's not reliable
2012-06-07T23:48:33 < zyp> some times it fail to execute the loader, some times it work
2012-06-07T23:49:17 < karlp> dekar: I did not try -O0, and I have no plans on ever doing so. at least not until I decide to run -O0 code too.
2012-06-07T23:51:20 <+dekar> karlp, I just suggested it since it might be a bug in your code brought up by an optimization option
2012-06-07T23:52:29 < karlp> after what I've been seeing and dealing with recently, I could almost believe that,
2012-06-07T23:52:59 < karlp> but if it doesn't work with -Os, ie, fails to _run_, when it works with other toolchains, then I don't really care, it's just broken :)
2012-06-07T23:53:10 < karlp> but it's building again in another window now we'll try again :)

2012-06-07T23:54:03 < karlp> nah, just print some good stats, always write a fixed blink image, and call it good :)
2012-06-07T23:54:12 <+dekar> karlp, well optimizations can be tricky, when I enabled lto it dropped all my exception handlers for example
2012-06-07T23:54:41 <+dekar> *interrupt handlers
2012-06-07T23:55:08 < zyp> anyway, have to fix page splitting to flash larger stuff
2012-06-07T23:55:09 <+dekar> on the other hand toolchains like SAT (and probably codesourcery as well) don't support lto to begin with
2012-06-07T23:56:36 < karlp> well, sat didn'twork for me earlier either, though that may have been bad makefile settings.
2012-06-07T23:56:53 < karlp> from the same source, the only one that worked with a memset call out of the box was the arm-launchpad
2012-06-07T23:57:02 < karlp> so I've run with that for the last few days.

2012-06-08T00:33:57 < zyp> yep
2012-06-08T00:34:02 < R2COM> so...it worked?
2012-06-08T00:34:11 < R2COM> its gona work just as regular texane stuff, but faster?
2012-06-08T00:34:14 < R2COM> any trade offs?
2012-06-08T00:34:27 < zyp> notice how the time from starting flash write to starting verification went from 32 seconds to 1 second in those logs ;)
2012-06-08T00:34:33 < R2COM> yes i noticed
2012-06-08T00:35:09 < zyp> well, I can't guarantee for it's stability
2012-06-08T00:35:42 < zyp> sometimes it fails when I run the seperate st-flash utility, haven't had it happen with st-util yet
2012-06-08T00:35:59 < zyp> so I can't claim it's reliable
2012-06-08T00:36:06 < R2COM> well...will use then and see
2012-06-08T00:36:13 < zyp> but as long as it works, it's fine
2012-06-08T00:37:05 < R2COM> zyp, you have any idea about question i posed before
2012-06-08T00:37:09 < R2COM> im messing with spi2 now
2012-06-08T00:37:16 < R2COM> im turning on its clock in rcc
2012-06-08T00:37:20 < R2COM> then turn on CR1 bits
2012-06-08T00:37:26 < R2COM> but not all bits are set
2012-06-08T00:37:30 < zyp> no, I don't know, and I don't want to think about it now :p
2012-06-08T00:37:41 < zyp> I've been doing enough thinking for today
2012-06-08T00:37:47 < R2COM> thats fine, will mess more with it
2012-06-08T00:39:09 < R2COM> did you modify it to work with F2/F4 only now?
2012-06-08T00:39:15 < zyp> no
2012-06-08T00:39:15 < R2COM> would it work with F1 as well?
2012-06-08T00:39:17 < R2COM> ok
2012-06-08T00:39:20 < zyp> sure
2012-06-08T00:39:27 < R2COM> ok thanks
2012-06-08T00:39:29 < zyp> I just modified the F2/F4 flashing mode
2012-06-08T00:42:20 < zyp> Steffann, you should give it a go as well, I want any issues rooted out before I submit it to texane :p
2012-06-08T00:47:16 < R2COM> oh i just received my f0 board
2012-06-08T00:48:36 < R2COM> oh it came with nice proto board
2012-06-08T00:48:42 < Tectu> Thorn, you arround?
2012-06-08T00:49:24 < Thorn> I am
2012-06-08T00:50:07 < Tectu> Thorn, can you provide the paste with your lcdSetWindow function from the ssd1289 controller?
2012-06-08T00:51:01 < Tectu> could you also provide the lcdFillArea() function using that?
2012-06-08T00:51:55 < Thorn> http://pastebin.com/u5LW3NiU
2012-06-08T00:52:55 < Thorn> I don't have a fill function but it should be pretty trivial
2012-06-08T00:53:39 < Thorn> LCD_REG = 0x22; for(int i=0; i<w*h; ++i) LCD_RAM = color;
2012-06-08T00:53:56 < Thorn> something like this (using fsmc)
2012-06-08T00:54:37 < Thorn> that's the fastest method I'm aware of
2012-06-08T00:54:51 < Thorn> you can draw a bitmap the same way too
2012-06-08T00:58:15 < Tectu> Thorn, i really don't get why this dosen't work with my lcd :(
2012-06-08T00:59:40 < Tectu> Thorn, idea?   http://pastebin.com/HChCYKVf
2012-06-08T01:00:14 < Tectu> when i go with    lcdFillArea(100, 100, 200, 200, Blue);   i get a blue line from 100 to 200, vertical
2012-06-08T01:00:15 < Tectu> nothing more
2012-06-08T01:01:54 < Thorn> look at line 5 of my paste
2012-06-08T01:02:19 < Thorn> the function takes x, y, w and h. not x1, y1, x2 and y2
2012-06-08T01:02:27 < Tectu> don't worry
2012-06-08T01:02:29 < Tectu> works now :)
2012-06-08T01:02:34 < Tectu> thanks for your help, Thorn !
2012-06-08T01:02:45 < Tectu> x1=w   y1=h

2012-06-08T01:03:44 < Thorn> the comment says x+w-1 <= 239 for a reason. the controller acts weird if these constraints are not satisfied

2012-06-08T01:06:34 < Rickta59> but that works
2012-06-08T01:06:43 < Rickta59> just wondering if i was doing something wrong
2012-06-08T01:07:02 < zyp> you have to run the commands in the specific order
2012-06-08T01:07:13 < zyp> each commands creates the files required by the next
2012-06-08T01:07:14 < Rickta59> the autogen.sh isn't mentioned that i see
2012-06-08T01:07:26 < zyp> now it is :p
2012-06-08T01:08:14 < Rickta59> does karlp on git show up here?
2012-06-08T01:08:45 < zyp> sure he does
2012-06-08T01:08:59 < Rickta59> * was wondering if that would probe him awake
2012-06-08T01:09:07 < zyp> but I can probably answer your questions
2012-06-08T01:09:22 < Rickta59> can you update the docs to tell people to run autogen.sh?
2012-06-08T01:11:04 < zyp> can't you?
2012-06-08T01:11:12 < Rickta59> i guess i could make an issue
2012-06-08T01:11:23 < Rickta59> sometimes it is easier to just ask the person who has checkin rights
2012-06-08T01:11:51 < zyp> why can't you make a patch?
2012-06-08T01:12:07 < Rickta59> i can do that .. can you check it in?
2012-06-08T01:12:15 < zyp> karlp has no more checkin rights than me and you do
2012-06-08T01:12:33 <+Steffann> dekar it seems TNT compiled well this time

2012-06-08T01:13:50 < R2COM> can it be that my CR register for SPI isnt set because the pins are not configured?
2012-06-08T01:13:55 < R2COM> though i dont see reason for that..
2012-06-08T01:14:00 < zyp> R2COM, no.
2012-06-08T01:14:03 < R2COM> if i write something to CR, it should be there...
2012-06-08T01:14:20 < zyp> should it really?
2012-06-08T01:14:34 < R2COM> yea..
2012-06-08T01:14:44 < R2COM> it has to obey :P

2012-06-08T01:14:58 < zyp> and what are you reading back?

2012-06-08T01:15:15 < R2COM> dont read anything
2012-06-08T01:15:30 < R2COM> ((SPI_TypeDef *) (SPI2_BASE)) -> CR1 |= (SPI_CR1_CPOL |
2012-06-08T01:15:30 < R2COM> SPI_CR1_CPHA | SPI_CR1_LSBFIRST | SPI_CR1_MSTR | SPI_CR1_SPE);
2012-06-08T01:15:33 < zyp> then how do you know it's not set?
2012-06-08T01:15:33 < R2COM> thats it
2012-06-08T01:15:37 < R2COM> im debugging
2012-06-08T01:15:41 < R2COM> step by step
2012-06-08T01:15:45 < zyp> right, then you're reading back
2012-06-08T01:15:54 < R2COM> so.. ?
2012-06-08T01:16:04 < zyp> so, what value are you reading back?
2012-06-08T01:16:08 < R2COM> 0x83
2012-06-08T01:16:17 < R2COM> it means CPOL,CPHA,LSBFIRST are set
2012-06-08T01:16:20 < zyp> and what do you write?
2012-06-08T01:16:29 < R2COM> those things on top
2012-06-08T01:16:35 < R2COM> SPE, MSTR
2012-06-08T01:16:40 <+Steffann> Care if that's something for tomorrow zyp ?
2012-06-08T01:16:43 < R2COM> plus SPOL CPHA LSBFIRST
2012-06-08T01:16:54 < zyp> Steffann, that's fine
2012-06-08T01:17:09 < R2COM> interesting thing is, that i read 0x83 even before i set the CR
2012-06-08T01:17:11 < zyp> Steffann, I'm not going to submit anything until tomorrow anyway
2012-06-08T01:17:57 <+Steffann> Used the flashloader from the bmp ?
2012-06-08T01:18:02 < R2COM> so, after i set it, im supposed to read the 0xc7
2012-06-08T01:18:09 < R2COM> but i read always 0x83 in debugger
2012-06-08T01:18:14 < R2COM> before setting, and after setting
2012-06-08T01:18:26 < zyp> try setting it from the debugger
2012-06-08T01:18:38 < R2COM> hm...how you do that?
2012-06-08T01:18:42 < zyp> set variable blah = 0xc7
2012-06-08T01:18:52 < zyp> where blah is a valid lvalue :p
2012-06-08T01:19:22 < R2COM> set variable (SPI_TypeDef *)(addr) = 0xc7 also fine?
2012-06-08T01:19:33 < R2COM> because its not variable, CR1 is in memory
2012-06-08T01:20:25 < R2COM> gdb) set variable (uint32_t*)(0x40003800) = 0xc7
2012-06-08T01:20:25 < R2COM> Left operand of assignment is not an lvalue.
2012-06-08T01:20:38 < zyp> put a * in front of it
2012-06-08T01:20:41 < zyp> to dereference it
2012-06-08T01:20:47 < zyp> *(uint…
2012-06-08T01:20:59 < R2COM> (gdb) set variable *(uint32_t*)(0x40003800) = 0xc7
2012-06-08T01:20:59 < R2COM> (gdb) p/x *(uint32_t *) 0x40003800
2012-06-08T01:20:59 < R2COM> $7 = 0x83
2012-06-08T01:20:59 < R2COM> (gdb)
2012-06-08T01:21:03 < R2COM> again i read that shit
2012-06-08T01:21:05 < R2COM> 0x83
2012-06-08T01:21:15 < zyp> good
2012-06-08T01:21:22 < zyp> that's interesting

2012-06-08T01:27:04 < blkcat> yes, safety improvements were undertaken after the chernobyl disaster.
2012-06-08T01:27:06 < R2COM> not human error... human pressure from some officials..etc
2012-06-08T01:27:22 < R2COM> that stuff was common in USSR
2012-06-08T01:27:59 < R2COM> once one general forced technicians and designer of some missile, to make some rework *on the fly* ... that was strictly prohibited by designer himself
2012-06-08T01:28:12 < R2COM> but he still forced him to run this procedure, to complete plan
2012-06-08T01:28:23 < R2COM> result was explosion and around 126 people dead right away
2012-06-08T01:28:37 < R2COM> but missile was not bad
2012-06-08T01:28:40 < blkcat> the soviets didn't exactly have an exacting safety culture, heh.

2012-06-08T01:34:50 < zyp> try writing it to 0 first
2012-06-08T01:37:46 < R2COM> http://shorttext.com/uc5dNj2
2012-06-08T01:37:48 < R2COM> didnt work
2012-06-08T01:38:52 < R2COM> now here is interesting thing
2012-06-08T01:38:57 < R2COM> first i try setting the whole CR to 0
2012-06-08T01:39:01 < R2COM> and it sets!
2012-06-08T01:40:03 < R2COM> but then... http://shorttext.com/6rnOeIP
2012-06-08T01:40:31 < R2COM> so i can set it to 0 from debugger, (because after that i read it as 0...so it worked), however, i cannot set it to anything else
2012-06-08T01:42:41 < R2COM> now thats weird...
2012-06-08T01:42:52 < R2COM> after i write anything in it, i read again 0x83
2012-06-08T01:43:05 < R2COM> after i write 0x00 to it, i read 0x0
2012-06-08T01:48:40 <+dekar> I compiled newlib with LTO
2012-06-08T01:48:59 <+dekar> -> GCC discarded like all of it
2012-06-08T01:49:03 <+dekar> :/
2012-06-08T02:28:31 < R2COM> interesting shit, sometimes when i have break point, and i run from beginning
2012-06-08T02:28:32 < R2COM> it just stucks
2012-06-08T02:28:37 < R2COM> and never reaches it
2012-06-08T02:28:40 < R2COM> restarting does NOT help
2012-06-08T02:28:48 < R2COM> restarting and REPLUGGING the board DOES help
2012-06-08T02:28:56 < R2COM> powering/off on
2012-06-08T02:30:31 < R2COM> but hell i dont understand why this SPI shit doesnt work
2012-06-08T02:30:37 < R2COM> i mean setting the CR1 register
2012-06-08T02:30:45 < R2COM> i tried, to configure it first, and THEN enable
2012-06-08T02:30:48 < R2COM> but same thing...
2012-06-08T02:30:52 <+dekar> R2COM, sounds like a memory problem - use of uninitialized memory for example
2012-06-08T02:31:07 < R2COM> im doing it this way:
2012-06-08T02:31:13 <+dekar> I also once had a problem where my .bss wasn't initialized due to a bug in my linkerscript
2012-06-08T02:31:25 < R2COM> // configure SPI2
2012-06-08T02:31:25 < R2COM> ((SPI_TypeDef *) (SPI2_BASE)) -> CR1 |= (SPI_CR1_CPOL |
2012-06-08T02:31:25 < R2COM> SPI_CR1_CPHA | SPI_CR1_LSBFIRST | SPI_CR1_MSTR);
2012-06-08T02:31:42 < R2COM> but before that i do this:
2012-06-08T02:31:55 < R2COM> ((SPI_TypeDef *)(SPI2_BASE)) -> CR1 = 0x00;
2012-06-08T02:37:43 < R2COM> i even tried this:
2012-06-08T02:37:45 < R2COM> ((SPI_TypeDef *)(SPI2_BASE)) -> CR1 = 0x00;
2012-06-08T02:37:55 < R2COM> ((SPI_TypeDef *)(SPI2_BASE)) -> CR1 = 0x87;
2012-06-08T02:38:05 < R2COM> after first line, i can see in debugger that CR1 is 0

2012-06-08T02:38:30 < R2COM> this kind of doesnt make sense
2012-06-08T03:01:55 < dongs> lots of blogging
2012-06-08T03:02:06 < dongs> R2COM: it makes perfect sense
2012-06-08T03:02:10 < dongs> some bits in CR register are write only
2012-06-08T03:02:13 < dongs> and go back to zero
2012-06-08T03:02:18 < R2COM> hm?
2012-06-08T03:02:31 < dongs> im not saying thats the case wiht SPI since I never fucked with raw registers on it, but its likely
2012-06-08T03:02:41 < dongs> in a lot of things  stuff like reset bits are write only
2012-06-08T03:02:49 < dongs> i.e. you write '1' to reset bit, then wehn you read it back, its back to zero
2012-06-08T03:03:23 < R2COM> uh no!
2012-06-08T03:03:31 < R2COM> in datasheet SPI_CR1 all bits are rw
2012-06-08T03:03:40 < dongs> dude.
2012-06-08T03:03:43 < dongs> < dongs> im not saying thats the case wiht SPI since I never fucked with raw registers on it, but its likely
2012-06-08T03:03:49 < R2COM> oh ok
2012-06-08T03:04:03 < R2COM> (06:04:52 PM) dongs: R2COM: it makes perfect sense
2012-06-08T03:04:03 < R2COM> (06:04:56 PM) dongs: some bits in CR register are write only
2012-06-08T03:04:14 < dongs> ok, are -> could be
2012-06-08T03:04:15 < dongs> shrug
2012-06-08T03:04:31 < R2COM> turns out that no... but it still does this shit
2012-06-08T03:04:43 < R2COM> did you use SPI at all?
2012-06-08T03:04:43 < dongs> im talking about mcus in general, that shit like that is possible, giving example of reset bits. who knows what hte fuck they do in SPI.
2012-06-08T03:04:47 < dongs> yes, using stdlib
2012-06-08T03:04:55 < dongs> wokrs perfectly fine.
2012-06-08T03:05:10 < R2COM> can you give fragment of code where you use its functions, i want to see sequence and what else is going on
2012-06-08T03:05:10 < dongs> in double-buffered DMA mode
2012-06-08T03:05:47 < dongs> http://bcas.tv/paste/results/cyZ5Bo42.html

2012-06-08T03:07:58 < R2COM> why SYSCFG?
2012-06-08T03:08:05 < dongs> the comment explains it.
2012-06-08T03:08:16 < dongs> syscfg for exti stuf.
2012-06-08T03:09:00 < R2COM> and why you do SPI_I2S_DeInit if you are only using SPI?
2012-06-08T03:09:02 < R2COM> not I2S?
2012-06-08T03:09:45 < dongs> thats the function name
2012-06-08T03:09:52 < dongs> stdlib spi/i2s shit handles both.
2012-06-08T03:10:02 < dongs> There's no SPI_DeInit
2012-06-08T03:10:16 < dongs> not that it matters anyway
2012-06-08T03:10:21 < dongs> all it does is toggles the reset bit
2012-06-08T03:10:41 < R2COM> uhh...fucking library notation, whoever did it all is retard
2012-06-08T03:11:05 < R2COM> so, it looks like before doing anything, one has to call DeInit?
2012-06-08T03:11:40 < dongs> not really
2012-06-08T03:11:53 < dongs> look at waht deinit does.
2012-06-08T03:12:00 < R2COM> lookin
2012-06-08T03:12:12 < dongs> all it dodes is resets the peripheral
2012-06-08T03:12:16 < dongs> set reset bit/ clear it
2012-06-08T03:19:35 < R2COM> i tried resetting first
2012-06-08T03:19:38 < R2COM> as that function does
2012-06-08T03:19:39 < R2COM> same shit
2012-06-08T03:19:44 < dongs> what 'shit'?
2012-06-08T03:19:48 < dongs> you mean it doesnt work?
2012-06-08T03:19:55 < R2COM> after i configure CR1 register
2012-06-08T03:19:58 < R2COM> its not being set
2012-06-08T03:20:04 < R2COM> gdb returns value of 0x83
2012-06-08T03:20:11 < dongs> oh no fucking idea.
2012-06-08T03:20:12 < R2COM> should return 0xc7
2012-06-08T03:21:41 < R2COM> so you just operate on those functions..
2012-06-08T03:21:49 < dongs> yes, because I just want shit to work
2012-06-08T03:21:56 < dongs> and I am not worried about what it does behind me
2012-06-08T03:22:57 < R2COM> ok im gona try that first then

2012-06-08T06:30:37 < R2COM> i have some improvement

2012-06-08T06:31:04 < R2COM> the MOSI pin never shows activity since startup
2012-06-08T06:31:20 < R2COM> i send data like this:

2012-06-08T06:31:35 < R2COM> while (SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_TXE) == RESET);

2012-06-08T06:32:02 < R2COM> and in the debug, i see that it passes that while loop and jumps to a function sending a data
2012-06-08T06:32:19 < R2COM> so it means, that after the board power up, there HAS to be an activity on the MOSI pin

2012-06-08T11:10:13 < zyp> and SPI2_MOSI are set to AF with correct AF chosen?
2012-06-08T11:10:17 < R2COM> yes
2012-06-08T11:10:52 < zyp> and SPI2 are configured in full-duplex or tx-only mode?
2012-06-08T11:11:23 < R2COM> http://pastebin.com/ccwSLrwY
2012-06-08T11:11:36 < R2COM> Master mode
2012-06-08T11:11:55 < zyp> sure, master mode was kind of obvious, since it generates clock
2012-06-08T11:12:22 < zyp> your paste doesn't seem to be loading for me
2012-06-08T11:12:31 < R2COM> what you mean?
2012-06-08T11:12:32 -!- pelrun__ [~pelrun@14-202-70-213.static.tpgi.com.au] has joined ##stm32
2012-06-08T11:12:47 < zyp> your link doesn't work
2012-06-08T11:12:51 < R2COM> heh
2012-06-08T11:12:57 < zyp> ok, worked now
2012-06-08T11:13:08 < zyp> yep, found your problem
2012-06-08T11:13:12 < R2COM> haha
2012-06-08T11:13:16 < R2COM> 1 second
2012-06-08T11:13:16 < zyp> you did the same error as dongs
2012-06-08T11:13:19 < R2COM> hmm
2012-06-08T11:13:24 < zyp> spi2.SPI_Direction = SPI_Direction_1Line_Tx;
2012-06-08T11:13:24 < R2COM> what error use stdperiph?
2012-06-08T11:13:32 < zyp> that is simplex mode
2012-06-08T11:13:35 < R2COM> well...its one line
2012-06-08T11:13:57 < zyp> when you use that mode, SPI2_MISO are used for both input and output
2012-06-08T11:14:40 < zyp> it's 1Line_Tx means «one-line bidirectional, now transmitting»
2012-06-08T11:15:09 < R2COM> i need then 2Lines_FullDuplex ?
2012-06-08T11:15:26 < zyp> if there is a mode with that name, yes
2012-06-08T11:17:34 < R2COM> that option sets BIDIMODE and BIDIOE to 1
2012-06-08T11:17:51 < R2COM> BIDIOE=1, output enabled... i want it
2012-06-08T11:18:06 < R2COM> BIDIMODE=1 - 1 line bidirectional data mode selected
2012-06-08T11:18:15 < R2COM> trying now
2012-06-08T11:19:05 < zyp> are you even reading what I say?
2012-06-08T11:19:40 < zyp> ok, let's do it this way
2012-06-08T11:19:48 < zyp> there are four ways of using spi
2012-06-08T11:20:10 < zyp> either tx-only, rx-only, tx and rx on different pins or tx and rx on same pin
2012-06-08T11:20:15 < zyp> which of those do you want?
2012-06-08T11:20:33 < R2COM> tx only
2012-06-08T11:22:07 < zyp> right
2012-06-08T11:22:14 < R2COM> hmm seems in that case i want BIDIMODE=0
2012-06-08T11:22:16 < zyp> then you don't want bidirectional mode
2012-06-08T11:22:20 < zyp> correct
2012-06-08T11:22:26 < R2COM> and also i want BIDIOE=1
2012-06-08T11:22:54 < zyp> correct
2012-06-08T11:23:19 < R2COM> lol!
2012-06-08T11:23:24 < R2COM> library doesnt have that option
2012-06-08T11:23:29 < zyp> oh, wait
2012-06-08T11:23:35 < zyp> it doesn't matter
2012-06-08T11:23:44 < zyp> BIDIOE aren't used when BIDIMODE=0
2012-06-08T11:23:52 < R2COM> oh
2012-06-08T11:24:11 < R2COM> #define SPI_Direction_2Lines_FullDuplex ((uint16_t)0x0000)
2012-06-08T11:24:11 < R2COM> #define SPI_Direction_2Lines_RxOnly     ((uint16_t)0x0400)

2012-06-08T11:24:29 < R2COM> BIDIMODE (bit15), BIDIOE(bit14)
2012-06-08T11:24:55 < zyp> right
2012-06-08T11:25:00 < zyp> just do FullDuplex
2012-06-08T11:25:05 < R2COM> i did
2012-06-08T11:25:07 < R2COM> now
2012-06-08T11:25:10 < R2COM> here is an interesting thing
2012-06-08T11:25:15 < R2COM> i loaded it already in chip
2012-06-08T11:25:18 < R2COM> and debugging
2012-06-08T11:25:25 < R2COM> what i did is, i went to a last lines of code
2012-06-08T11:25:31 < R2COM> where it is about to send data to buffer
2012-06-08T11:26:08 < R2COM> i am stepping, and reading the p/x *(uint32_t *) 0x4000380c  which is SPI_DR register
2012-06-08T11:26:11 < R2COM> and i get 0x
2012-06-08T11:26:20 < R2COM> is it normal?
2012-06-08T11:26:37 < zyp> that DR contains 0?
2012-06-08T11:26:41 < R2COM> i was thinking like...if i put something in that register, and then read it, i should get what i put
2012-06-08T11:26:41 < R2COM> yes
2012-06-08T11:26:47 < zyp> no
2012-06-08T11:26:54 < zyp> I mean
2012-06-08T11:26:57 < zyp> yes it's normal
2012-06-08T11:27:05 < zyp> it's two different registers on the same addr
2012-06-08T11:27:23 < R2COM> hmm.. ok 1 sec, hooking to scope then
2012-06-08T11:27:27 < zyp> when you write, you write to the output buffer, when you read, you read the input buffer
2012-06-08T11:29:01 < R2COM> hm
2012-06-08T11:30:33 -!- Steffanx [~Steffanx@ip4da726ae.direct-adsl.nl] has joined ##stm32

2012-06-08T11:31:33 < R2COM> no
2012-06-08T11:31:34 < R2COM> same shit
2012-06-08T11:31:42 < R2COM> upon power-up, i see clock
2012-06-08T11:31:48 < R2COM> 5.25MHz
2012-06-08T11:31:58 < R2COM> but NO activity on MOSI pin (PB15)
2012-06-08T11:32:06 < zyp> what data are you sending?
2012-06-08T11:32:12 < R2COM> one byte
2012-06-08T11:32:18 < jon1012> someone tried to use enc28j60 with stm32 ?
2012-06-08T11:32:19 < zyp> containing what?
2012-06-08T11:32:21 < R2COM> uint8_t d0 = 0xd9; // 11011001, test data0
2012-06-08T11:32:33 < zyp> ok
2012-06-08T11:32:45 < R2COM> // sending the data while (SPI_I2S_GetFlagStatus(SPI2, SPI_I2S_FLAG_TXE) == RESET) { } SPI_I2S_SendData(SPI2,  (uint8_t)d0);
2012-06-08T11:32:58 < R2COM> bad paste, but its in the code i gave link to
2012-06-08T11:33:11 < R2COM> except that in that code i corrected it to fullduplex
2012-06-08T11:33:40 < R2COM> you can also notice in the code, prescaler _8, and 42MHz/8 =  5.25MHz
2012-06-08T11:33:56 < R2COM> and i see this frequency on SPI2_SCK (PB13)
2012-06-08T11:35:41 < R2COM> im thinking.. maybe there must be some kind of delay in between?
2012-06-08T11:37:11 < zyp> looks correct
2012-06-08T11:37:19 < R2COM> yep.
2012-06-08T11:37:29 < R2COM> but MOSI pin is dead silent, right from power up
2012-06-08T11:37:33 < zyp> hmm, new datasheet revision
2012-06-08T11:37:43 < zyp> interesting
2012-06-08T11:37:44 < zyp> Starting from Silicon revision Z, USB OTG full-speed interface is now
2012-06-08T11:37:44 < zyp> available for all STM32F405xx devices.
2012-06-08T11:38:04 < zyp> that explains why my F405 got both OTG_FS and OTG_HS
2012-06-08T11:39:18 < R2COM> datasheet or reference manual
2012-06-08T11:39:22 < R2COM> i see reference manual is same
2012-06-08T11:39:28 < zyp> datasheet
2012-06-08T11:39:54 < zyp> there was a lot confusion about what were present and not in the previous revision
2012-06-08T11:41:08 < R2COM> ok
2012-06-08T11:42:07 < R2COM> i checked
2012-06-08T11:42:14 < R2COM> SCK and MOSI pins there,
2012-06-08T11:42:15 < zyp> I had to change my design to use OTG_HS when I discovered that OTG_FS were only present in F407, then after I assembled the boards I discovered by poking the registers for OTG_FS that it were still present
2012-06-08T11:42:16 < R2COM> lol
2012-06-08T11:42:41 <+Steffanx> And it also works zyp ?
2012-06-08T11:42:56 <+Steffanx> or you didn't/couldn't try?
2012-06-08T11:43:02 < zyp> Steffanx, according to new datasheet it should
2012-06-08T11:43:09 <+Steffanx> You have REV Z ?
2012-06-08T11:43:15 < zyp> I didn't try because the pins aren't hooked up on my board
2012-06-08T11:43:27 < zyp> that is posible
2012-06-08T11:43:29 < zyp> possible
2012-06-08T11:43:51 < R2COM> darn
2012-06-08T11:43:58 < R2COM> i have no idea what about this SPI
2012-06-08T11:44:04 < R2COM> i recheck all already
2012-06-08T11:44:16 <+Steffanx> ST and it's annoying revision system
2012-06-08T11:44:25 < R2COM> there might be some trivial thing which i just dont see
2012-06-08T11:44:33 <+Steffanx> They go from 1 to B to Z to whatever is next
2012-06-08T11:45:14 < R2COM> ?
2012-06-08T11:45:39 <+Steffanx> Nothing, just a random rant about the revision system from ST :P
2012-06-08T11:46:12 < zyp> Steffanx, you should see the version numbers for shit I work with then
2012-06-08T11:46:15 < R2COM> zyp how did you configure spi, maybe there is something else u did
2012-06-08T11:46:15 < R2COM> ?
2012-06-08T11:46:35 < zyp> lots of weird stuff that I don't understand how anybody came up with :p
2012-06-08T11:47:00 <+Steffanx> I have the same problem with this one and it's only 1 character :D
2012-06-08T11:47:12 < R2COM> im also not messing/setting NSS, since i dont have any multiple receiving devices
2012-06-08T11:47:37 < zyp> R2COM, http://cgit.jvnv.net/suzumebachi/commit/?h=stm32f4&id=2a34130
2012-06-08T11:48:27 < R2COM> well
2012-06-08T11:48:29 < zyp> Steffanx, here's a bunch of characters, and if I'm lucky, all the other characters are equal and the last one is incremented for each new version :p

2012-06-08T11:49:11 <+Steffanx> Ha Mr Laurenceb_
2012-06-08T11:49:45 < R2COM> accel is spi?
2012-06-08T11:50:02 < zyp> accel is i2c, gyro is spi
2012-06-08T11:50:02 < R2COM> can you show its init function?
2012-06-08T11:50:08 < R2COM> gyros init?
2012-06-08T11:50:14 < Laurenceb_> sup
2012-06-08T11:50:23  * Laurenceb_ is pissed with the ltc2481 adc
2012-06-08T11:50:31 < zyp> R2COM, it's in the previous commit
2012-06-08T11:50:33 < zyp> http://cgit.jvnv.net/suzumebachi/commit/?h=stm32f4&id=55d20ed
2012-06-08T11:50:41 < Laurenceb_> seems acessing it over i2c corrupts the next reading
2012-06-08T11:51:03 < zyp> Laurenceb_, nah, it's just your bad luck again
2012-06-08T11:51:08 < Laurenceb_> heh
2012-06-08T11:51:16 < Laurenceb_> its relatively small
2012-06-08T11:51:27 < Laurenceb_> but seems to be a real effect, very annoying
2012-06-08T11:51:39 < Laurenceb_> im getting crosstalk from the digital logic
2012-06-08T11:52:02 < zyp> is this the new board, that we told you should have four layers? :p
2012-06-08T11:52:19 < Laurenceb_> heh
2012-06-08T11:52:22 < R2COM> i see you set SSM and SSI to 1
2012-06-08T11:52:43 < zyp> Laurenceb_, seriously, your problems is a result of shitty board layout
2012-06-08T11:52:44 < Laurenceb_> thwe interference is only when the adc is accessed
2012-06-08T11:52:50 < R2COM> which is, software slave management enabled, and internal slave select
2012-06-08T11:52:58 < Laurenceb_> using the i2c bus doesnt cause issues
2012-06-08T11:53:40 < Laurenceb_> if i let it buffer some values without reads its ok
2012-06-08T11:53:46 < Laurenceb_> but that give slag ;(
2012-06-08T11:53:50 < Laurenceb_> *lag
2012-06-08T11:53:56 < zyp> R2COM, sounds about right
2012-06-08T11:54:18 < R2COM> but i guess...im my case i dont have to mess with those SSM,SSI bits?
2012-06-08T11:54:32 < R2COM> since, i have only one "receiver" connected to my SPI2
2012-06-08T11:54:43 < zyp> so do I
2012-06-08T11:55:02 < zyp> I set those bits to say that «this device will never be a slave»
2012-06-08T11:55:02 < R2COM> then why you enable software slave management?
2012-06-08T11:55:14 < R2COM> maybe that matters...
2012-06-08T11:55:14 < R2COM> hm
2012-06-08T11:55:17 < zyp> because I don't need hardware slave management
2012-06-08T11:55:39 < zyp> enabling software slave management is a bit of a misnomer, it means disabling hardware slave management :p
2012-06-08T11:56:06 < R2COM> in my code i have this commented out:
2012-06-08T11:56:07 < R2COM> //spi2.SPI_Mode = SPI_NSS_Soft;
2012-06-08T11:56:30 < R2COM> i noticed, that before, when this was not commented out, i didnt even get a clock output
2012-06-08T11:57:03 < zyp> well, then you probably had it set to slave
2012-06-08T11:57:23 < R2COM> #define SPI_NSS_Soft                    ((uint16_t)0x0200)
2012-06-08T11:57:23 < R2COM> #define SPI_NSS_Hard                    ((uint16_t)0x0000)
2012-06-08T11:57:27 < R2COM> thats what in library
2012-06-08T11:57:31 < zyp> exactly
2012-06-08T11:57:36 < zyp> so it sets SSM but not SSI
2012-06-08T11:57:56 < R2COM> but i need to set both to 1?
2012-06-08T11:58:01 < zyp> yes
2012-06-08T11:58:16 < zyp> SSI = 1 for master, 0 for slave
2012-06-08T11:58:16 < R2COM> turns out that this library doesnt even have this option?
2012-06-08T11:58:31 < zyp> and SSM should be 1 if you don't have SPI2_NSS connected
2012-06-08T11:58:57 < zyp> I don't have any idea about what your library has and don't
2012-06-08T11:59:24 < R2COM> hmm so not setting those bits actually could be problem?
2012-06-08T11:59:47 < zyp> likely not, you would probably not get a clock if it went into slave mode
2012-06-08T12:00:02 < zyp> but should still be fixed
2012-06-08T12:00:31 < R2COM> hm...
2012-06-08T12:00:32 < R2COM> ok
2012-06-08T12:00:32 < zyp> it's a case of «does happen to work, even if behavior is undefined»
2012-06-08T12:00:51 < R2COM> well...darn...what else could be wrong then
2012-06-08T12:01:06 < zyp> no idea
2012-06-08T12:01:27 < zyp> I'd try poking the registers directly from the debugger
2012-06-08T12:01:43 < zyp> that's what I usually do when learning how peripherals work
2012-06-08T12:02:05 < R2COM> yeah

2012-06-08T13:11:42 < karlp> I wonder if he got spi working in the end?
2012-06-08T13:16:16 < dongs> probably not
2012-06-08T13:17:25 < karlp> I was going to give him my working spi code as well,
2012-06-08T13:18:42 < dongs> spi isnt that hard.
2012-06-08T13:20:06 < dongs> my analol'g-fu is nonexistent, would there be 433mhz harmonics off 27mhz clock signal travelling over 10cm cable run?

2012-06-08T13:54:43 <+Steffanx> zyp  you used the blackmagic probe flash loader for that?
2012-06-08T13:56:09 <+Steffanx> No.. it's different :P
2012-06-08T14:03:48 < zyp> I wrote it myself, it's pretty trivial
2012-06-08T14:04:28 < zyp> I'm going to attach the source in the patch when I submit it
2012-06-08T14:12:30 < Laurenceb> dongs: i was thinking about catcopter
2012-06-08T14:12:46 < Laurenceb> you know what other 4 pointed shape could be used?
2012-06-08T14:13:16 < Laurenceb> swastikacopter :P
2012-06-08T14:13:46 < karlp> zyp: I had a look at it, but haven't applied it anywhere or tried it :)
2012-06-08T14:13:49 < karlp> looks good though
2012-06-08T14:14:20 < karlp> I actually have an f4 discovery board, it's just not something I plug in very often.
2012-06-08T14:15:38 < Tectu> why arent there any f4 development boards besides the discovery btw?
2012-06-08T14:15:45 < karlp> because you haven't made one?
2012-06-08T14:15:49 < Tectu> i mean there are hundrets of different f103 boards
2012-06-08T14:15:52 < Tectu> but no f4
2012-06-08T14:15:52 < karlp> what the hell sort of question is that?
2012-06-08T14:16:06 < Tectu> karlp, didn't you sleep well this night? o0
2012-06-08T14:16:08 < karlp> f1 has been around about 100 years longer than f4 too
2012-06-08T14:16:20 < zyp> Tectu, there are other
2012-06-08T14:16:28 < Tectu> zyp, le link?
2012-06-08T14:16:41 < zyp> ST got one expensive one, and then there are third party ones like the waveshare stuff dongs are using
2012-06-08T14:16:58 < Tectu> zyp, there is no real f4 board from waveshare
2012-06-08T14:17:01 < Tectu> beside these coreboards
2012-06-08T14:17:10 < zyp> Tectu, http://www.st.com/internet/evalboard/product/252216.jsp
2012-06-08T14:19:57 < Tectu> zyp, yeah, and where are waveshares development board, which are not just coreboards?
2012-06-08T14:24:18 < dongs> Laurenceb: lol
2012-06-08T14:24:27 < dongs> Laurenceb: that'll sure rile up bloggers
2012-06-08T14:27:38 < Laurenceb> alternatively a star of david hexacopter
2012-06-08T14:28:02 < Laurenceb> or both, for aerial battle
2012-06-08T14:28:28 < zyp> Tectu, ah, right, those are still just F1 and F2
2012-06-08T14:29:56 < zyp> http://www.wvshare.com/product/Port407V.htm <- assuming you mean this when you say coreboard?
2012-06-08T14:31:03 < zyp> it's still a development board, though, so my argument still stands
2012-06-08T14:31:40 < karlp> does olimex make an f4 board yet?
2012-06-08T14:32:03 < zyp> haven't seen one yet, but it can't be far away
2012-06-08T14:32:29 < zyp> and the maple guys supposedly have some F4 stuff coming
2012-06-08T14:52:43 < karlp> hey, look, /b being genuinely funny, _and_ SFW! http://24.media.tumblr.com/tumblr_m4vj4edvCa1r6c2i9o1_1280.jpg

2012-06-08T15:29:04 < Tectu> sorry

2012-06-08T15:30:37 < Tectu> zyp, and yes, no F4 boards beside the discovery and the eval board from ST at all
2012-06-08T15:31:10 <+Steffanx> and some other board

2012-06-08T15:31:56 < Tectu> Steffanx, yes, but that are core boards
2012-06-08T15:32:01 < Tectu> Steffanx, i talk about development boards
2012-06-08T15:32:11 <+Steffanx> hmpf
2012-06-08T15:32:28 < Tectu> zyp, dafuq is that? new STericson device? :D
2012-06-08T15:32:58 < zyp> no, it's my F4 board that I made a few months ago
2012-06-08T15:34:24 < Tectu> yeah, but does not look like development board at all?
2012-06-08T15:34:42 < Tectu> Steffanx, did you get that board you linked?
2012-06-08T15:34:50 <+Steffanx> No
2012-06-08T15:35:05 < zyp> Tectu, of course it is a development board, I made it to develop my quadrotor software
2012-06-08T15:35:13 < Tectu> zyp, aye
2012-06-08T15:35:28 < Tectu> am i the only one on earth which does not do quadrotor?
2012-06-08T15:35:38 < zyp> and it has a bunch of shit that wouldn't be present on a normal user board
2012-06-08T15:35:48 < zyp> so it's pretty clear that it's a devboard :p
2012-06-08T15:36:11 < Tectu> i am sorry sir.
2012-06-08T15:36:19 < Tectu> didn't try to be offense at at all :D

2012-06-08T15:49:10 < cjbaird> embedded systems are a natural progression from microcomputers, and Euro was big on those?

2012-06-08T15:52:21 < dongs> or dudes who do sheep (in case of .nz)
2012-06-08T15:52:54 < cjbaird> ausfags are into computers because auswomen are shit in bed...
2012-06-08T15:56:43 < cjbaird> The plan with 'Multiculturalism' was to import as many overseas girls as possible, but the first thing they learned here was doing it corpse style.. -_-

2012-06-08T16:09:02 < Rickta59> do people have any thoughts good or bad about libmaple?
2012-06-08T16:09:26 < zyp> the lowlevel libmaple looks rather decent
2012-06-08T16:09:41 < zyp> IIRC
2012-06-08T16:09:48 < zyp> I haven't looked at it for a year
2012-06-08T16:09:49 < Rickta59> yeah that is what it seemed to me
2012-06-08T16:10:16 < Rickta59> i'm new to the stm arm stuff and I'm looking around at the available lib stuff
2012-06-08T16:12:09 < zyp> libopencm3 seems like a pretty good choice
2012-06-08T16:12:42 < dongs> whats wrong with stdperiphlib
2012-06-08T16:12:43 < Rickta59> what is the most popular
2012-06-08T16:12:54 < zyp> dongs, except for being horribly messy?
2012-06-08T16:13:09 < dongs> its not that bad
2012-06-08T16:13:15 < dongs> Rickta59: if y ou want official vendor support, stdperiphlib.
2012-06-08T16:13:21 < dongs> if you're a lunix faggot who edits code in vi, it doesnt matter what you use
2012-06-08T16:13:28 < dongs> cause you'll be rewriting it anyway
2012-06-08T16:13:45 < Rickta59> there ya go I'm a linux fag
2012-06-08T16:13:50 < dongs> libopencm3 is ok but all it is is renaming of all registers and removing functionality
2012-06-08T16:14:00 < dongs> and renaming all ISR function names etc
2012-06-08T16:14:50 < Rickta59> is there any chance that any of the available libs would work cross arm vendor?
2012-06-08T16:15:01 < dongs> libopencm3 sorta does
2012-06-08T16:15:06 < dongs> if you use highlevel shit.

2012-06-08T16:15:35 < Rickta59> is that their m3/m4 stuff?
2012-06-08T16:15:42 < dongs> didnt think they had any m4 stuff
2012-06-08T16:15:46 < dongs> stellaris is thier m3 stuff.
2012-06-08T16:16:02 < dongs> http://www.ti.com/ww/en/mcu/cortex_m4f/?DCMP=cortexm4f&HQS=cortexm4-b o neat
2012-06-08T16:16:13 < dongs> lol 80mhz
2012-06-08T16:16:13 < dongs> wtf
2012-06-08T16:16:21 < dongs> All LM4F variants include the ARM Cortex-M4F core with the single precision floating point at 80 MHz ???
2012-06-08T16:16:27 < dongs> way2fail, TI
2012-06-08T16:17:22 < zyp> hmm, 65nm
2012-06-08T16:17:26 < zyp> F4 is 90nm
2012-06-08T16:17:34 < dongs> 80mhz and 32k sram
2012-06-08T16:17:39 < dongs> wtf are tehy targeting?
2012-06-08T16:17:51 < zyp> battery efficiency?
2012-06-08T16:18:09 < zyp> I guess 65nm would consume less power per cycle than 90nm
2012-06-08T16:19:08 < zyp> if it's about using the least amount of power per floating point operation, it might beat F4
2012-06-08T16:24:56 < Rickta59> so those 3 libs .. anything else that is of interest ?
2012-06-08T16:27:55 < dongs> no.
2012-06-08T16:28:02 < dongs> personally i'd just use vendor shit
2012-06-08T16:28:06 < dongs> i.e. stellarisware for TI and stdperiphlib for ST
2012-06-08T16:28:21 < dongs> you aren't gonna have 1:1 shit thats hardware specific between platforms anyway
2012-06-08T16:28:52 < Rickta59> are any of the peripheral in common? gpio? timers?
2012-06-08T16:29:02 < dongs> nope.
2012-06-08T16:29:09 < dongs> which is why.
2012-06-08T16:29:33 < Rickta59> hmm .. well seems like you just need to pick your poison and learn to love it
2012-06-08T16:29:41 < Rickta59> any reason to not use ST stuff?
2012-06-08T16:29:45 < dongs> nope.
2012-06-08T16:29:47 < dongs> it works perfectly fine.
2012-06-08T16:30:10 < Rickta59> business wise they keep the chip factory humming and pumping them out?
2012-06-08T16:30:31 < dongs> oh they're not going anywhere if thats what you mean
2012-06-08T16:30:46 < Rickta59> seems like when i looked for availability on octopart they were always plentiful and inexpensive
2012-06-08T16:31:01 < Rickta59> I'm buying in qty 1 ish
2012-06-08T16:31:01 < dongs> yes.
2012-06-08T16:31:15 < dongs> for example STM32F103CxT6 is ~$2/ea in qty
2012-06-08T16:31:27 < dongs> 48qfp  cortex m3
2012-06-08T16:31:37 < dongs> STM32F405RG is around ~$6
2012-06-08T16:31:43 < Rickta59> yeah .. just wondered if it was a bait and switch thing ..
2012-06-08T16:31:44 <+Steffanx> 2$ where?
2012-06-08T16:31:49 < dongs> Steffanx: in my office
2012-06-08T16:32:09 <+Steffanx> I paid 2.25$
2012-06-08T16:32:17 <+Steffanx> For the C8
2012-06-08T16:32:24 < dongs> terrible.
2012-06-08T16:32:35 <+Steffanx> Cheapest i could find
2012-06-08T16:32:37 < dongs> 2$ for C8 and 2.5 for CB here.
2012-06-08T16:33:25 <+Steffanx> 'in my offfice' == black market stuff?
2012-06-08T16:33:34 < dongs> noes?
2012-06-08T16:33:39 < dongs> i only buy legit stuff.
2012-06-08T16:34:23 <+Steffanx> You pay 2$ for 1k?
2012-06-08T16:34:31 < dongs> tray
2012-06-08T16:34:44 <+Steffanx> I even used ebay to get them D:
2012-06-08T16:35:13 < dongs> ebay isnt legit :)
2012-06-08T16:35:20 <+Steffanx> For me it is
2012-06-08T16:37:07 < Rickta59> these seem to be around the price i'd like to spend STM32F051C8T6 < $2
2012-06-08T16:37:43 < zyp> dongs can probably get those for < $1 :p
2012-06-08T16:37:44 <+Steffanx> That's a cortex-m0 ..
2012-06-08T16:37:51 < Rickta59> yeah that is fine Steffanx
2012-06-08T16:37:57 <+Steffanx> ok
2012-06-08T16:38:12 <+Steffanx> Dongs has it's own clone factory
2012-06-08T16:38:17 <+Steffanx> *his
2012-06-08T16:38:17 < Rickta59> : )
2012-06-08T16:38:52 < dongs> F0 isn't widely available yet
2012-06-08T16:39:08 <+Steffanx> Not cloned yet..
2012-06-08T16:39:11 < dongs> Ya.
2012-06-08T16:39:37 < Rickta59> it will be a while before I get up to speed
2012-06-08T16:39:45 < dongs> I wonder how many arduino-styles ST trolled by calling F0 shit F05, making it look like its next step after F4
2012-06-08T16:40:01 < dongs> look its new and its got bigger number!!
2012-06-08T16:40:06 < zyp> how's that different from F45?
2012-06-08T16:40:22 < dongs> ? where's F45
2012-06-08T16:40:23 < zyp> sorry, F405
2012-06-08T16:40:26 < dongs> you mean F405?
2012-06-08T16:40:26 < Rickta59> they just sent me a free board so i guess i got trolled
2012-06-08T16:41:19 <+Steffanx> You have to be very stupid to think that dongs
2012-06-08T16:41:34 < zyp> «arduino»
2012-06-08T16:41:36 < zyp> so yeah
2012-06-08T16:41:37 < Rickta59> i saw it as a step up in low power vs msp430
2012-06-08T16:42:08 < dongs> Steffanx: what zyp said
2012-06-08T16:42:25 <+Steffanx> dongs and his phobias
2012-06-08T16:42:28 < dongs> zyp: why tyhe fuck are you using unicode quiotation amrks

2012-06-08T17:33:30 < dongs> Steffanx: i didnt route it
2012-06-08T17:34:58 < FUZxxl> Hello!
2012-06-08T17:35:23 < FUZxxl> I want to compile a C program for the STM32l micro controller.
2012-06-08T17:35:35 < FUZxxl> I mean,
2012-06-08T17:35:43 < FUZxxl> I have such an STM32l discovery board.
2012-06-08T17:35:48 -!- Thorn [~Thorn@unaffiliated/thorn] has joined ##stm32
2012-06-08T17:35:58 < FUZxxl> It seems like I need to set up the stack on my own, right?
2012-06-08T17:36:12 < FUZxxl> What exactly should I set for the stack boundary?
2012-06-08T17:36:12 < dongs> if you're programming in vi writing asm, yes.
2012-06-08T17:36:27 < FUZxxl> dongs: ?
2012-06-08T17:38:11 < dongs> i dont know how to answer your question because it does not  compute
2012-06-08T17:39:33 < FUZxxl> Well, I want to write (in C) a program for this microcontroller.
2012-06-08T17:39:44 < FUZxxl> I use texane's stlink to access the device.
2012-06-08T17:39:46 < Rickta59> start on this page http://www.st.com/internet/evalboard/product/250990.jsp
2012-06-08T17:40:00 < FUZxxl> I use Linux and the GNU toolchain.
2012-06-08T17:40:20 < FUZxxl> I use the linker script provided in some of stlink's examples.
2012-06-08T17:40:26 < Rickta59> have you looked at the tutorial that comes with the texane stlink package
2012-06-08T17:40:29 < FUZxxl> I don't want, however, use any libraries
2012-06-08T17:40:39 < FUZxxl> Rickta59:Yes.
2012-06-08T17:40:48 < Rickta59> and you have tried the blink examples
2012-06-08T17:40:51 < FUZxxl> Did I miss something?
2012-06-08T17:40:57 < FUZxxl> Yeah, they all compile and run just fine.
2012-06-08T17:41:06 < FUZxxl> I am now starting on my own.
2012-06-08T17:41:11 < Rickta59> hmm .. so you compiled a c program for the stm32l
2012-06-08T17:41:19 < FUZxxl> But I don't want to use the libraries and includes provided.
2012-06-08T17:41:19 < Rickta59> just use that as a base to get started
2012-06-08T17:41:28 < Rickta59> well then you are on your own
2012-06-08T17:41:39 < FUZxxl> I only want to know, what I need to do to set up the stack.
2012-06-08T17:41:45 < Thorn> you need to write your own startup code then
2012-06-08T17:41:52 < FUZxxl> Yeah.
2012-06-08T17:42:02 < FUZxxl> What does the startup code needs to do?
2012-06-08T17:42:20 < Thorn> the stack is set up by the hardware, initial sp value is read from address 0
2012-06-08T17:42:22 < Rickta59> you might look at the startup code used by the libs and includes you don't want to use
2012-06-08T17:42:59 < Thorn> 1) sets up all the clocks 2) copies .data to ram 3) zeroes out .bss 4) calls main()
2012-06-08T17:42:59 < FUZxxl> Rickta59: Well, the blink example has none.  I failed to compile the "official" stuff, since I don't have Windows.
2012-06-08T17:43:25 < Rickta59> i'm also just getting started
2012-06-08T17:43:43 < Rickta59> and the approach i'm taking is to look at the startup.s files used by stdperiphlib
2012-06-08T17:43:51 < FUZxxl> Okay.
2012-06-08T17:44:04 < FUZxxl> Where can I find that lib?
2012-06-08T17:44:14 < Rickta59> that first link i supplied
2012-06-08T17:44:39 < FUZxxl> In that Windows-installer?
2012-06-08T17:44:56 < dongs> ..
2012-06-08T17:45:01 < dongs> no stdperiphlib is a .zip file
2012-06-08T17:45:03 < Rickta59> i'm thinking more the firmware download zip
2012-06-08T17:45:21 < Rickta59> ah .. it is an ex
2012-06-08T17:45:22 < Rickta59> e
2012-06-08T17:45:36 < Rickta59> so yah you are going to have to find a windows machine to extract it
2012-06-08T17:45:51 < Rickta59> * i'm using the F0 board not the L board
2012-06-08T17:45:52 < FUZxxl> Rickta59: Yeah, I managed to unpack it using Wine
2012-06-08T17:46:04 < FUZxxl> What's the difference?
2012-06-08T17:46:17 < Rickta59> F is the M0 core
2012-06-08T17:46:32 < Thorn> you can often extract exe under linux, unzip/unrar will recognize their archives even if they're sfx
2012-06-08T17:46:35 < Rickta59> and the zip i downloaded was just a bunch of source and headers
2012-06-08T17:47:18 < FUZxxl> ...
2012-06-08T17:47:20 < FUZxxl> hm...
2012-06-08T17:47:41 < FUZxxl> There is no "stdperiphlib" in this package.
2012-06-08T17:47:58 < Rickta59> well i have no idea how to help you help yourself then sorry
2012-06-08T17:48:01 < FUZxxl> okay.
2012-06-08T17:48:33 < FUZxxl> So, what does the startup code need to do anyway? I guess it's just setting up the stack and probably zeroing out the bss section, isn't it?
2012-06-08T17:48:56 < Thorn> see my earlier answer
2012-06-08T17:49:13 < FUZxxl> Rickta59: Can you email me that stdperiphlib?
2012-06-08T17:49:17 < Rickta59> no
2012-06-08T17:49:21 < Rickta59> it is for the wrong chip
2012-06-08T17:49:27 < Rickta59> you can download it yourself if you want
2012-06-08T17:49:35 < Thorn> what stm32 family are you using?
2012-06-08T17:49:37 < Rickta59> but it isn't going to be appropriate for your chip
2012-06-08T17:49:41 < FUZxxl> Thorn: Well, the chip has no memory mapped to address 0x0
2012-06-08T17:50:01 < FUZxxl> Rickta59: Yeah, okay. I thought just as an inspiration.
2012-06-08T17:50:10 < Thorn> 1) it has to 2) memory can be aliased
2012-06-08T17:50:15 < FUZxxl> Thorn: I have the STM32l discovery board.
2012-06-08T17:50:17 < Rickta59> all it does it put the top of the stack address at 0
2012-06-08T17:50:20 < FUZxxl> Let me look
2012-06-08T17:50:26 < Rickta59> and then setups up a jump address for the reset vector
2012-06-08T17:50:35 < FUZxxl> The microcontroller is STM32L152RBT6
2012-06-08T17:50:50 < FUZxxl> okay
2012-06-08T17:53:18 < Thorn> www.st.com -> micros & memories -> microcontrollers -> stm32 -> STM32 L1 Ultra Low Power -> resources -> firmware  -> stm32l1xx standard peripherals library
2012-06-08T17:53:26 < Thorn> see, easy enough
2012-06-08T17:57:41 < FUZxxl> :-)
2012-06-08T17:57:49 < FUZxxl> Now I need to understand that...
2012-06-08T17:59:19 < zyp> oh, texane merged my patch already, that was fast
2012-06-08T18:00:17 < zyp> some 9 minutes after I created a pull request
2012-06-08T18:02:17 < Thorn> look under Libraries\CMSIS\Device\ST\STM32L1xx\Source\Templates\gcc_ride7
2012-06-08T18:04:30 < zyp> Laurenceb, if you wanted to test fast F4 flashing, it's in texane master now :p
2012-06-08T18:06:11 < FUZxxl> Thorn: Thank you!

2012-06-08T20:09:46 < jon1012> Steffanx, working well with gcc ?
2012-06-08T20:09:55 <+Steffanx> Never tried
2012-06-08T20:09:59 <+Steffanx> Only know it exists

2012-06-08T20:10:23 < jon1012> ok
2012-06-08T20:10:37 < jon1012> I have a couple dp83848 dev board around, I'll give it a try
2012-06-08T20:10:49 < jon1012> (rmii phy seemed to cost more than enc28j60)
2012-06-08T20:10:55 < jon1012> enc28j60 => 2.5 usd
2012-06-08T20:11:09 < jon1012> dp83848 or KSZ**** => 5 usd at least
2012-06-08T20:11:43 <+izua> enc28j60 is pretty lulzy
2012-06-08T20:11:51 <+izua> only thing i have around that works at base10-T
2012-06-08T20:12:11 <+Steffanx> Yeah, with a good phy you at least have real e thernet :)
2012-06-08T20:12:15 < zyp> jon1012, chip or complete board?
2012-06-08T20:12:20 < jon1012> chip
2012-06-08T20:12:25 <+izua> plus, you can always get away with weird lines when people ask you why it does a different thing on their router/switch led
2012-06-08T20:12:33 < zyp> dp83848 is at 2.95 for 1 at digikey
2012-06-08T20:12:36 <+izua> "because it's not a computer!" "because i programmed it to do that"
2012-06-08T20:13:00 <+izua> are there any stm32 dev boards with a phy?
2012-06-08T20:13:13 <+Steffanx> Yes
2012-06-08T20:13:21 <+Steffanx> F4 .. don't know
2012-06-08T20:13:27 < zyp> and enc28j60 is at 3.54 for 1 at digikey
2012-06-08T20:14:22 < jon1012> in france, rs, dp => 5.89 eur per 1, enc28j60 => 2.61 eur per 1
2012-06-08T20:15:08 < zyp> izua, STM3240G-EVAL
2012-06-08T20:18:19 < ratatata> any cheaper boardas ?

2012-06-08T20:20:40 <+izua> oh god
2012-06-08T20:20:45 <+izua> the one with the arduino like connectors
2012-06-08T20:20:48 <+izua> WHY GOD WHY
2012-06-08T20:21:03 <+izua> why do people have to take bad designs and make them standards
2012-06-08T20:23:29 <+izua> but yeah, i hope it will be out soon

2012-06-08T20:23:41 <+izua> unless it will become a raspberry
2012-06-08T20:24:35 <+izua> how are things with the rpi anyway? last time i heard of them, farnell took over manufacture
2012-06-08T20:24:50 < jon1012> nobody can gets its hand on one
2012-06-08T20:25:05 < jon1012> and it's still closed hardware
2012-06-08T20:25:12 < jon1012> :)
2012-06-08T20:25:15 < cjbaird> Another 15 days before mine shows up.
2012-06-08T20:25:18 <+izua> i like their marketing scheme
2012-06-08T20:25:32 <+izua> "buy the initial historical prototypes fopr insane amount of money, this will make history"
2012-06-08T20:25:42 < zyp> I hear several people get their
2012-06-08T20:25:56 < zyp> Laurenceb got his, even though he didn't even want one
2012-06-08T20:26:24 <+izua> wait, how does that work?
2012-06-08T20:26:31 < cjbaird> In a way, the "hyperhyped gadget flooded into everyone's hands are the first priority" the RPi people did will probably work in their Evil Scheme to get them into Education.
2012-06-08T20:28:09 < cjbaird> Compare that with what the OLPC people did, where only a elistist small number should get one, and the Foundation had to work and work to try to get Government educational groups interested, effectively offering no-cost trails and such.
2012-06-08T20:29:11 < zyp> izua, I guess he was the one here most excited for it, but didn't want to admit it :p
2012-06-08T20:30:40 < cjbaird> Good to see that Microsoft and Intel _haven't_ tried to FUD and sabotage the RPi, though. Their super-small form-factor HTPC product announcements waited until after the RPi shipped.

2012-06-08T21:25:30 < Rickta59> is there a way to have the discovery boards provide some kind of serial interface with using an ftdi chip? specifically the F0 board
2012-06-08T21:25:45 < Rickta59> serial as in it would be ok if it was a libusb endpoint
2012-06-08T21:28:04 <+Steffanx> swv ..
2012-06-08T21:28:36 < jpa-> "with using an ftdi chip"? you mean with or without?
2012-06-08T21:28:38 <+Steffanx> The stlink/v2 supports that
2012-06-08T21:28:44 <+Steffanx> i guess without :)
2012-06-08T21:28:49 < jpa-> probably :)
2012-06-08T21:28:59 < jpa-> you could use CP2012 chip instead :P
2012-06-08T21:29:03 <+Steffanx> Ha
2012-06-08T21:29:16 <+Steffanx> or \pl23[something]

2012-06-08T21:29:33 <+Steffanx> Yes
2012-06-08T21:29:41 < jpa-> yeah.. not really possible :)
2012-06-08T21:29:47 <+Steffanx> but only Rickta59 knows what he really meant
2012-06-08T21:29:50 < jpa-> you could write some hack around stlink :P
2012-06-08T21:30:01 <+Steffanx> swv is not hackish :P
2012-06-08T21:30:04 < zyp> how is it, F0 doesn't have usb?
2012-06-08T21:30:05 <+Steffanx> ok, a little
2012-06-08T21:30:09 < jpa-> (or does F0 discovery have stlinkv2?)
2012-06-08T21:30:15 < zyp> jpa-, yes
2012-06-08T21:30:18 <+Steffanx> It's a new board, so ...
2012-06-08T21:30:22 <+Steffanx> Ah, zyp knows it all
2012-06-08T21:30:36 < jpa-> does some program support swv? :)
2012-06-08T21:30:44 <+Steffanx> Software no
2012-06-08T21:30:50 < zyp> no, I just seem to recall that it had the 6-pin connector and not the 4-pin for external swd
2012-06-08T21:30:57 <+Steffanx> Except for the TruStudio windows stuff
2012-06-08T21:31:13 < zyp> but he was fine with a libusb endpoint!
2012-06-08T21:31:20 < karlp> stlinkv1 is end of lifed from ST anyway,
2012-06-08T21:31:25 < karlp> or, "not recommended for new designs"
2012-06-08T21:31:36 < karlp> so I presume the f0 discovery has a v2 like all the others.
2012-06-08T21:31:48 < zyp> yes, it does
2012-06-08T21:32:01 < zyp> «it includes an ST-LINK/V2 embedded debug tool»
2012-06-08T21:32:27 < zyp> so swv from F0 to computer is possible
2012-06-08T21:33:03 < karlp> so, zyp, you've been in super productive mode recently :) ....

2012-06-08T21:34:41 < zyp> Steffanx, didn't you work on it once?
2012-06-08T21:35:03 <+Steffanx> I was reverse engineering it.. until i found the docs yes :P
2012-06-08T21:35:49 < zyp> does it do anything by default?
2012-06-08T21:36:32 <+Steffanx> Not that i know of.. you have to enable it iirc
2012-06-08T21:38:11 <+Steffanx> Oh, the bmp just pushes it to an endpoint, just like the stlink
2012-06-08T21:38:19 < zyp> yep
2012-06-08T21:38:20 <+Steffanx> i think gsmcmull1n said something about that a while ago

2012-06-08T21:48:03 <+izua> is there even any driver for a chip, that comes with windows, and does usb-serial and COM port emulation out of the box?
2012-06-08T21:48:45 <+Steffanx> Not that i know of
2012-06-08T21:48:46 <+izua> i thought ftdi had that for a while, thus the reason behind the reverse engineering of ftdi client code, but apparently they also need drivers for CDC to COM emulation ><
2012-06-08T21:49:29 <+Steffanx> windows has standard CDC stuff, but you still need an INF-file

2012-06-08T22:07:43 < Rickta59> so one option would be using the swd protocol in some bizarre manner?
2012-06-08T22:07:53 <+Steffanx> swv
2012-06-08T22:08:15 <+Steffanx> You just have to give the texane stuff support for it
2012-06-08T22:08:18 < zyp> Steffanx, do you know anything about what the stlink accepts?
2012-06-08T22:08:27 <+Steffanx> accepts?

2012-06-08T22:09:40 < zyp> Steffanx, punching out values via ITM
2012-06-08T22:10:08 < zyp> but stlink wouldn't recognize just anything since it's async
2012-06-08T22:10:23 < zyp> so I need to configure it to spit out what stlink expects
2012-06-08T22:10:26 < zyp> and what is that?
2012-06-08T22:11:11 <+Steffanx> Uhm ..
2012-06-08T22:13:19 < Laurenceb_> nobody knows
2012-06-08T22:13:34 < Laurenceb_> but stlink is much faster now :P
2012-06-08T22:13:40 < Laurenceb_> i got about 15KB/s
2012-06-08T22:14:04 <+Steffanx> Yeah, but it still takes longer than a second even when the fw is only 10k
2012-06-08T22:14:42 <+Steffanx> I actually don't know much about the stm32-stlink part zyp
2012-06-08T22:14:53 < Laurenceb_> a second isnt veyr long

2012-06-08T22:15:12 < Laurenceb_> oh noes
2012-06-08T22:15:18 <+Steffanx> 10k/15ks = less than a second :P
2012-06-08T22:15:28 < zyp> the gdbserver does some slowness before it starts flashing
2012-06-08T22:15:30 < Laurenceb_> it takes like 200ms to click a mouse
2012-06-08T22:15:35 < zyp> i.e. before it invokes my code
2012-06-08T22:15:50 < Laurenceb_> yeah i see that too
2012-06-08T22:16:15 <+Steffanx> I just used TruStudio + usb logger to get some info about the stlink-host part zyp
2012-06-08T22:16:24 < zyp> flashing a 1M image takes just over 40s here, and the first ten is spent on some internal shit

2012-06-09T00:01:34 < jpa-> snprintf and a single write helped :P

2012-06-09T08:27:44 <+dekar> zippe, TNT, SAT and YAG were the latest ones, CS is some version I found on my disk - I posted the date code though
2012-06-09T08:27:58 <+dekar> they're all open source so you can compare the compile options
2012-06-09T09:14:19 < zippe> Hmm, yeah, so TNT is 4.7, the rest are probably still on 4.6
2012-06-09T09:14:33 < zippe> But TNT is building Linaro, not gcc-embedded
2012-06-09T09:14:44 < zippe> Do you have the arm baremetal toolchain in there?
2012-06-09T09:16:00 < zippe> And TNT is m3-only

2012-06-09T13:27:43 < ratatata> but shorter
2012-06-09T13:28:05 < ratatata> and n in the plce of m
2012-06-09T13:28:43 <+Steffanx> n00b without the b? :)

2012-06-09T13:34:03 <+Steffanx> uh?
2012-06-09T13:36:30 < Tectu> Steffanx, when do the netherlands play today?
2012-06-09T13:36:36 < Tectu> gf is reallife AFK abd needs result :D
2012-06-09T13:36:44 <+Steffanx> 18.00
2012-06-09T13:36:46 < Tectu> and i don't have any clue about soccer
2012-06-09T13:36:52 < Tectu> Steffanx, against germany, right?
2012-06-09T13:36:56 <+Steffanx> No, Denmark
2012-06-09T13:37:00 < Tectu> ah
2012-06-09T13:37:21 < Tectu> can I ask you in the evening for some results? :D
2012-06-09T13:37:33 <+Steffanx> Hmpf :P
2012-06-09T13:37:39 <+Steffanx> Go watch it
2012-06-09T13:38:12 < Tectu> naaa
2012-06-09T13:38:15 < Tectu> it's so boring :D
2012-06-09T13:38:19 < Tectu> i don't like soccer
2012-06-09T13:38:27 < Tectu> my gf also does just watch the netherlands :D
2012-06-09T13:38:34 < Tectu> don't like sports either
2012-06-09T13:38:45 <+Steffanx> lol
2012-06-09T13:39:02 < Tectu> as i said, patriotistic :D
2012-06-09T13:39:11 <+Steffanx> Germany is Wednesday
2012-06-09T13:39:17 < Tectu> aye
2012-06-09T13:39:22 < Tectu> also 1800?
2012-06-09T13:39:28 <+Steffanx> 20.45
2012-06-09T13:39:32 < Tectu> okay
2012-06-09T13:39:39 < Tectu> are dutch people even good at soccer?
2012-06-09T13:39:50 <+Steffanx> but you are in a different time zone/line :P
2012-06-09T13:40:06 < Tectu> no, just my server
2012-06-09T13:40:12 <+Steffanx> You know they lost the world cup final in 2010 :P
2012-06-09T13:40:13 < Tectu> switzerland, remember?
2012-06-09T13:40:24 < Tectu> Steffanx, aaah :D   so they are not that bad, aye
2012-06-09T13:40:32 < Tectu> Steffanx, GMT+01:00 here
2012-06-09T13:40:59 <+Steffanx> Oh, same here
2012-06-09T13:41:04 <+Steffanx> Fix your server time
2012-06-09T13:41:20 < Tectu> not my server
2012-06-09T13:41:27 < Tectu> and server also not here ;)
2012-06-09T13:42:09 < Tectu> how about switzerland in last EM and WM?
2012-06-09T13:42:23 < Tectu> afaik they sucked, only got to quarter final somewhere, right?
2012-06-09T13:42:36 <+Steffanx> Don't know :P
2012-06-09T13:42:47 <+Steffanx> Don't care about switzerland
2012-06-09T13:42:53 <+Steffanx> :P
2012-06-09T13:43:57 < Tectu> ass :P
2012-06-09T13:44:45 < BrainDamage> they should draw every match
2012-06-09T13:45:20 < Tectu> haha
2012-06-09T13:45:25 <+Steffanx> That's better for the italian match fixers BrainDamage ?
2012-06-09T13:45:32 <+Steffanx> No, it's not
2012-06-09T13:45:32 < ratatata> Steffanx, exactlyb, n00b without b
2012-06-09T13:46:20 < BrainDamage> I don't care, I don't watch sport, I prefer doing it
2012-06-09T13:46:37 <+Steffanx> That's all up to you
2012-06-09T13:46:57 < BrainDamage> or better, better than I don't care, I don't even know
2012-06-09T13:47:08 < Tectu> using ENC28J60 shouldn't be that hard, right?
2012-06-09T13:48:53 < zyp> no, just kind of pointless when you can get a stm32 with internal mac
2012-06-09T13:49:13 < BrainDamage> what about phy?
2012-06-09T13:49:18 < BrainDamage> eithernet phy
2012-06-09T13:49:24 < BrainDamage> -I
2012-06-09T13:49:47 <+Steffanx> You need that, but it's still better than a enc28j60
2012-06-09T13:49:48 <+Steffanx> *an
2012-06-09T13:50:34 < Tectu> zyp, just have STM32F103VET without internal Ethernet, also ENC28J60 on my board
2012-06-09T13:50:48 < Tectu> did someone ever use that chip?
2012-06-09T13:50:52 < zyp> yes
2012-06-09T13:51:07 < zyp> some guy come here talking about doing just that yesterday
2012-06-09T13:51:15 <+Steffanx> jon something iirc
2012-06-09T13:51:28 <+Steffanx> <jon1012>
2012-06-09T13:51:40 < ratatata> Steffanx, what is iirc ?
2012-06-09T13:51:51 <+Steffanx> if i remember correctly
2012-06-09T13:51:52 < zyp> if I recall correctly
2012-06-09T13:51:58 < Laurenceb_> maybe you could attach a SD card and so SAMBA?
2012-06-09T13:52:00 <+Steffanx> I go for my version zyp
2012-06-09T13:52:11 < zyp> Steffanx, pretty much same meaning
2012-06-09T13:52:20 <+Steffanx> samba Laurenceb_ ?!
2012-06-09T13:52:30 <+Steffanx> As in that windows sharing stuff?
2012-06-09T13:52:39 < Laurenceb_> as opposed to using rpi
2012-06-09T13:52:48 < Laurenceb_> as you were saying
2012-06-09T13:53:13 <+Steffanx> I don't think it can do 9-10MB/s ..
2012-06-09T13:53:17 < Tectu> so none of your guys here does have some sharable sourcecode yet, right?
2012-06-09T13:53:26 < Tectu> Steffanx, ENC28J60 is 10 T-base
2012-06-09T13:53:48 <+Steffanx> Even the samba process has a load of 75% on the rpi with 9-10MB/s Laurenceb_ ...
2012-06-09T13:53:59 < Laurenceb_> oh
2012-06-09T13:54:07 < pelrun__> I saw the mikroelectronika stm32 boards yesterday, theyre using a lan8726a phy
2012-06-09T13:54:15 <+Steffanx> That sentence is not correct, but you probably understand what i meant :P
2012-06-09T13:54:17 < pelrun__> seems to be fairly small and easy to route
2012-06-09T13:54:26 < zyp> Steffanx, isn't smb known to be rather inefficient?
2012-06-09T13:54:42 <+Steffanx> Probably
2012-06-09T13:54:54 < zyp> are you sharing with windows computers?
2012-06-09T13:55:00 < zyp> otherwise, you could just use nfs
2012-06-09T13:55:00 <+Steffanx> No, OS X
2012-06-09T13:55:07 < zyp> then nfs
2012-06-09T13:55:10 <+Steffanx> No :P
2012-06-09T13:55:20 <+Steffanx> The current kernel has no nfs support
2012-06-09T13:55:30 < zyp> oh
2012-06-09T13:55:30 < BrainDamage> use ssh with10mbit key!
2012-06-09T13:55:50 < zyp> then you could try afpd
2012-06-09T13:55:51 < zyp> :p
2012-06-09T13:56:06 <+Steffanx> And the ethernet connection drops anyway :P
2012-06-09T13:56:10 <+Steffanx> So it's useless
2012-06-09T13:56:24 < zyp> sounds too slow to be useful anyway
2012-06-09T13:56:42 <+Steffanx> What? 9-10Mbyte/s isn't that bad
2012-06-09T13:56:50 <+Steffanx> On an 100mbit network
2012-06-09T13:56:53 < zyp> what for?
2012-06-09T13:57:05 <+Steffanx> Basic ftp/samba sharing stuff
2012-06-09T13:57:11 <+Steffanx> Nah, I was just messing around
2012-06-09T13:57:15 <+Steffanx> And it terribly failed
2012-06-09T13:57:26 < zyp> that's just it, 100mbit networks is too slow to be useful for file transfer stuff :p
2012-06-09T13:57:27 <+Steffanx> I'll get me a real NAS when i need something like that
2012-06-09T13:57:40 <+Steffanx> No, it's fast enough for my purposes
2012-06-09T13:57:53 <+Steffanx> My pc can multitask you know
2012-06-09T13:58:42 < zyp> yes, and to do more you'd like it to access files even faster :p
2012-06-09T13:58:56 <+Steffanx> It's just storage
2012-06-09T13:59:06 <+Steffanx> backup stuff
2012-06-09T13:59:33 <+Steffanx> Anyway, it was just a test and it failed
2012-06-09T14:00:50 < zyp> my storage server is fast enough that the gigabit ethernet connection becomes the bottleneck, and you're talking about speeds only a tenth of that
2012-06-09T14:01:25 <+Steffanx> Yes yes, but it's still fast enough for me :P
2012-06-09T14:01:51 < zyp> even single hard drives nowadays pushes data way faster than 100 Mb/s
2012-06-09T14:03:05 < zyp> although, I guess it doesn't have to be fast if you don't use it :p
2012-06-09T14:03:54 < zyp> I have a storage server because that lets me move all the noisy harddrives out of my workstation and into another room where I can't hear them :p
2012-06-09T14:04:18 <+Steffanx> My hdd's aren't noise at all
2012-06-09T14:04:27 <+Steffanx> Or do you use 10k rpm drives?
2012-06-09T14:04:39 <+Steffanx> *noisy
2012-06-09T14:05:58 < zyp> no, normal 7200rpm drives
2012-06-09T14:06:26 < zyp> and I'm not talking about just the drive, but the entire infrastructure to house them with cooling and all
2012-06-09T14:07:04 <+Steffanx> You did talk about the driver, but .. nah nvm :P
2012-06-09T14:07:08 <+Steffanx> *drives
2012-06-09T14:07:17 < zyp> of course
2012-06-09T14:07:34 < zyp> but if I don't have drives in my workstation, I don't need to cool them either
2012-06-09T14:07:37 < BrainDamage> you're getting 10 MB with smb on a rpi as nas?
2012-06-09T14:07:41 < Laurenceb_> http://www.eizo.com/global/products/duravision/fdh3601/
2012-06-09T14:07:43 < BrainDamage> 10M/s*
2012-06-09T14:07:49 <+Steffanx> BrainDamage, yes
2012-06-09T14:07:58 <+Steffanx> but it terribly fails after a while
2012-06-09T14:07:59 < BrainDamage> from usb or sd?
2012-06-09T14:08:01 <+Steffanx> USB
2012-06-09T14:08:09 <+Steffanx> External hdd
2012-06-09T14:08:39 < zyp> Laurenceb_, I hear the display dongs is using does the same resolution at 22"
2012-06-09T14:08:50 < Laurenceb_> yeah
2012-06-09T14:09:35 <+Steffanx> I need a magnifying glass for a screen like that :P
2012-06-09T14:19:37 < Tectu> can i make GDB outputting a variable on a given interval, without halting the program?
2012-06-09T14:23:32 < Laurenceb_> i think so
2012-06-09T14:23:38 < Laurenceb_> less sure about with texane
2012-06-09T14:27:40 < dongs> Tectu: standard feature in any IDE
2012-06-09T14:27:41 < dongs> watch window
2012-06-09T14:28:06 < dongs> o rite u said gdb
2012-06-09T14:28:29 < Tectu> dongs, do you have friends?
2012-06-09T14:29:01 < dongs> no
2012-06-09T14:33:41 < gsmcmullin> Tectu: You can do 'watch <var>' and then commands <n>; cont; end
2012-06-09T14:33:58 < gsmcmullin> It'll show you when your variable changes.
2012-06-09T14:34:11 < gsmcmullin> It does halt the program, but hopefully not for too long.
2012-06-09T14:34:18 < Tectu> thanks gsmcmullin

2012-06-09T15:14:11 < Tectu> he trolled before it was cool
2012-06-09T15:14:12 < dongs> in 4x less space
2012-06-09T15:14:17 < pelrun__> I'm actually working on a contract atm that's in the rc space, and I was seriously considering adding an osd to it (since it's just a couple of discrete components on some stm32 pins)
2012-06-09T15:14:51 < Laurenceb_> you know theres a maxim ic that does osd?
2012-06-09T15:14:52 < pelrun__> seeing osd's like that thing is just funny to me now
2012-06-09T15:14:57 < pelrun__> yeah, for $20
2012-06-09T15:15:03 < Laurenceb_> who cares
2012-06-09T15:15:15 < Laurenceb_> when its veyr small quantity
2012-06-09T15:15:17 < pelrun__> or I can do it for 10c
2012-06-09T15:15:21 < pelrun__> it's not small quantity
2012-06-09T15:15:27 < pelrun__> this is going to be a commercial product
2012-06-09T15:15:31 < Laurenceb_> ah
2012-06-09T15:16:03 < Laurenceb_> i was wonderng about doing color osd using multiple timers
2012-06-09T15:16:14 < pelrun__> I don't really see the need for colour
2012-06-09T15:16:26 < pelrun__> but it'd be pretty cool
2012-06-09T15:16:27 <+Steffanx> Everything needs color nowadays
2012-06-09T15:16:34 <+Steffanx> (and usb)
2012-06-09T15:16:35 < pelrun__> actually, have a look at lft's stuff
2012-06-09T15:16:46 < Tectu> Steffanx, bluetooth! you forgot bluetooth!
2012-06-09T15:16:46 < pelrun__> he generates colour pal signals from a small avr
2012-06-09T15:16:47 < Laurenceb_> couple of timers doing the PAL stuff
2012-06-09T15:16:49 < pelrun__> it's insane

2012-06-09T15:17:22 < Tectu> Steffanx, and at least 16GB of DDRIII
2012-06-09T15:17:44 < pelrun__> if an avr can do it, it should be trivial for an arm
2012-06-09T15:17:59 < pelrun__> of course, he's using a bit of a trick to do it, so it wouldn't really work for NTSC
2012-06-09T15:18:17 < Tectu> what's NTSC?
2012-06-09T15:18:38 <+Steffanx> I like his fancy boards

2012-06-09T15:19:14 < dongs>  < Laurenceb_> you know theres a maxim ic that does osd?
2012-06-09T15:19:18 < dongs> yeah its textonly a nd shit
2012-06-09T15:19:27 < dongs> with stm32 you can do like fully graphical shit, double buffered.
2012-06-09T15:19:34 < pelrun__> dongs, exactly

2012-06-09T15:22:23 < pelrun__> basically overlaying text/graphics onto an existing video signal
2012-06-09T15:23:20 < Tectu> is that hard to do?
2012-06-09T15:23:33 < Tectu> looks nice
2012-06-09T15:27:15 < pelrun__> not really
2012-06-09T15:27:53 < pelrun__> synchronising with the hsync/vsync pulses is the only tricky part
2012-06-09T15:27:59 < pelrun__> I found this http://www.rcgroups.com/forums/showthread.php?t=1473207
2012-06-09T15:28:23 < pelrun__> which uses the comparator on an avr to do it, pity the stm32 doesn't have one
2012-06-09T15:28:42 < pelrun__> or you could spend money on a separate sync separator chip (bleh)
2012-06-09T15:28:43 < Tectu> i never ever used AVRs comperator

2012-06-09T15:29:28 < Laurenceb_> yes
2012-06-09T15:29:31 <+Steffanx> L1 yes
2012-06-09T15:29:33 < pelrun__> F1's definitely don't
2012-06-09T15:29:33 <+Steffanx> Not F1

2012-06-09T15:30:27 < Laurenceb_> it seems silly but i guess it kind of works
2012-06-09T15:31:15 <+Steffanx> I used a fast external comparator + external interrupt :)
2012-06-09T15:31:30 < pelrun__> that'll do it too
2012-06-09T15:32:17 < pelrun__> just for my application it's not really an intended function, just a nice bonus if I can sneak the hardware in there trivially (so pretty much just a few resistors and caps)

2012-06-09T16:48:22 < zyp> this is with LTO?
2012-06-09T16:48:23 <+Steffanx> There has to be a good reason why SAT is 20k larger ..
2012-06-09T16:48:39 <+dekar> zyp, yeah I compiled whole newlib with LTO
2012-06-09T16:48:48 <+Steffanx> I still don't know what LTO means :)
2012-06-09T16:48:55 < zyp> link time optimization
2012-06-09T16:49:01 <+dekar> Steffanx, well if you look at SAT it says "LTO-disabled"
2012-06-09T16:49:10 < zyp> i.e. optimization across several translation units
2012-06-09T16:49:30 < zyp> stuff that normal optimization doesn't catch
2012-06-09T16:49:43 <+dekar> I also added the new and uber fast GOLD linker
2012-06-09T16:49:54 <+dekar> but it has problems understanding linkerscripts
2012-06-09T16:50:07 <+Steffanx> So => trash :P

2012-06-09T16:52:08 <+dekar> zyp, gold seems to have some linker script support, it ignores "KEEP" though and complains about "INCLUDE"

2012-06-09T17:03:21 <+dekar> on the other hand I guess we'll get multicore cortex-m as well
2012-06-09T17:03:34 <+Steffanx> nxp has them ..
2012-06-09T17:03:47 <+dekar> yeah I think someone showed them to me before
2012-06-09T17:04:15 <+dekar> the OMAP4 has two cortex-m0 as well
2012-06-09T17:04:34 <+Steffanx> 2 :S
2012-06-09T17:04:35 < zyp> no, m3
2012-06-09T17:04:51 < zyp> and OMAP5 got two m4
2012-06-09T17:05:15 <+Steffanx> 2 :S
2012-06-09T17:05:44 <+dekar> Steffanx, I think they're meant to control radios and the like
2012-06-09T17:05:56 < zyp> or camera stuff
2012-06-09T17:07:07 < zyp> at least, I believe that's what they do on the OMAP4-thing I got at work
2012-06-09T17:08:14 <+dekar> Steffanx, besides that a cortex-m takes up barely any space on the die compared to the cortex-a
2012-06-09T17:08:39 < zyp> yeah
2012-06-09T17:09:00 < zyp> remember that the die contains two a9s
2012-06-09T17:09:13 < zyp> a couple of m3s can't be very noticeable :p
2012-06-09T17:09:14 <+dekar> yeah it's a dualcore

2012-06-09T17:11:47 < zyp> I once counted seven in that OMAP4 reference platform

2012-06-09T17:13:12 < zyp> and there might of course be more cores present that I don't even know about :)
2012-06-09T17:15:21 <+dekar> like the ninja core in the Tegra3
2012-06-09T17:15:41 <+dekar> a completely transparent and invisible 5th core
2012-06-09T17:16:31 < zyp> is it really invisible?
2012-06-09T17:16:52 <+Steffanx> Yeah, the used invisible paint
2012-06-09T17:17:14 <+Steffanx> they
2012-06-09T17:17:38 < zyp> I mean, to be actually able to use it in a sane way, I assume that the OS should have explicit control over it
2012-06-09T17:17:45 <+dekar> Steffanx, they didn't use paint :/ it's just in another dimension!

2012-06-09T17:20:07 <+Steffanx> or left, whatever you want
2012-06-09T17:20:38 <+dekar> zyp, people tend to install linux on it and use that
2012-06-09T17:21:02 <+dekar> though the people working with tegra at our company just switched to some freescale
2012-06-09T17:22:53 < dongs> i.MEXI
2012-06-09T17:30:40 <+dekar> dongs, so will you benchmark TNT vs armCC for us?
2012-06-09T17:31:06 <+dekar> since I don't have a license, I can't do it
2012-06-09T17:32:26 < zyp> of course he won't… then he wouldn't be able to troll about how armcc is better :p

2012-06-09T17:33:33 < dongs> dekar: sure
2012-06-09T17:33:38 < dongs> what do i do?
2012-06-09T17:33:45 < dongs> is it just some .c file or someshit?
2012-06-09T17:34:05 < dongs> link me to wahtever
2012-06-09T17:34:13 <+dekar> umm what? start by compiling TNT
2012-06-09T17:34:28 < dongs> what
2012-06-09T17:34:42 < dongs> isnt TNT = gcc???
2012-06-09T17:34:54 <+dekar> it contains GCC yeah
2012-06-09T17:35:00 < dongs> then no?........
2012-06-09T17:35:07 <+dekar> oh you want to compile what I compiled
2012-06-09T17:35:09 < dongs> I thought you had some retarded testsuite
2012-06-09T17:35:19 < dongs> you cant compile gcc with anything except itself
2012-06-09T17:35:20 <+dekar> can't do that, it's proprietary
2012-06-09T17:35:39 <+dekar> compile whatever you want with both
2012-06-09T17:35:52 < dongs> oh, this guy who talks about prop programs PLCs
2012-06-09T17:35:58 < dongs> and he thinks he's a master programmer beacuse of that
2012-06-09T17:36:01 < dongs> yeah ok.
2012-06-09T17:36:47 < karlp> don't knock ladder code man
2012-06-09T17:37:09 < karlp> there's some seriously woooly "code" written in ladders, and they get paid a fortune to fix anything
2012-06-09T17:37:18 <+dekar> we could take some st example and compile it I guess
2012-06-09T17:38:08 < dongs> i dont see how compiling gcc with armcc (even if it was possible) would result in bigger/smaller/whatever binaries produced by said gcc
2012-06-09T17:38:29 < zyp> dongs, nobody said that
2012-06-09T17:38:35 <+dekar> dongs, yeah troll on
2012-06-09T17:38:39 < dongs> isnt that what he's saying?
2012-06-09T17:38:45 < dongs> <+dekar> umm what? start by compiling TNT
2012-06-09T17:38:46 < dongs> ?
2012-06-09T17:38:49 <+dekar> dongs, I'll search for some example and link it to you
2012-06-09T17:39:05 <+dekar> dongs, I said you should pick anything and compile it with both TNT and armcc
2012-06-09T17:39:13 < dongs> oh right
2012-06-09T17:39:15 < dongs> but i dont have lunix
2012-06-09T17:39:28 < dongs> or time to wait 5 hours for gcc to compile itself
2012-06-09T17:39:34 <+dekar> dongs, got that, thus I said I'll find some open source project we can compile on both
2012-06-09T17:39:43 <+dekar> dongs, how about eLUA?
2012-06-09T17:39:59 <+dekar> or nuttx?
2012-06-09T17:40:09 < dongs> howea bout you compile my shit since i have makefiles for gcc in it
2012-06-09T17:40:17 < dongs> and ithen i dont have to get any extra stuff
2012-06-09T17:40:21 <+Steffanx> Haha

2012-06-09T18:10:31 <+Steffanx> dongs uses O3
2012-06-09T18:10:55 < zyp> you can't compare optimization levels across different compilers
2012-06-09T18:11:06 < zyp> they don't translate
2012-06-09T18:11:07 <+dekar> GCC often gets slower with -O3
2012-06-09T18:11:25 <+Steffanx> We talk about code size here anyway dekar :P
2012-06-09T18:11:28 <+dekar> clang even has O levels higher than 3 :)
2012-06-09T18:11:44 <+dekar> Steffanx, zyp asked me to do it
2012-06-09T18:11:53 <+Steffanx> Never listen to zyp
2012-06-09T18:12:12 <+dekar> I'll stop when you make TNT beat armcc :P

2012-06-09T18:13:30 <+Steffanx> ok, have fun dekar
2012-06-09T18:13:44 <+dekar> still it's like 9k smaller than yagarto :)
2012-06-09T18:15:53 < upgrdman> what is bss?
2012-06-09T18:16:02 < Laurenceb__> GCC gets fastest with -Os usually fo rme
2012-06-09T18:16:10 < Laurenceb__> on arm
2012-06-09T18:16:13 <+Steffanx> fastest and smallest?
2012-06-09T18:16:48 < Laurenceb__> yes
2012-06-09T18:17:20 <+dekar> Steffanx, especially when running from flash loading more opcodes costs time
2012-06-09T18:17:27 <+dekar> so code density can gain a lot

2012-06-09T18:21:35 < Laurenceb__> what toolchain is that?
2012-06-09T18:22:31 <+dekar> still TNT
2012-06-09T18:23:22 < Laurenceb__> ah
2012-06-09T18:24:37 <+dekar> upgrdman, bss is memory initialized with zero
2012-06-09T18:24:54 <+dekar> that gets done at startup and doesn't take up any space on flash
2012-06-09T18:27:55 <+dekar> Steffanx, to use LTO pass "-Os -flto -fuse-linker-plugin -fwhole-program" to the linker and "-flto -fuse-linker-plugin" to the compiler
2012-06-09T18:32:58 < Laurenceb__> so TNT is working now on debian?
2012-06-09T18:33:22 <+dekar> yes
2012-06-09T18:33:26 <+dekar> and netBSD
2012-06-09T18:34:32 < Laurenceb__> hmm ill have to try then
2012-06-09T18:37:25 <+dekar> TNT compiles newlib with __DYNAMIC_REENT__ now, meaning that you have to provide a reent struct for each context (e.g. interrupt/thread)
2012-06-09T18:37:35 <+dekar> well if you use syscalls at least
2012-06-09T18:37:44 < Laurenceb__> what are syscalls?
2012-06-09T18:37:47 < Laurenceb__> malloc etc?
2012-06-09T18:38:02 <+dekar> malloc, sprintf yeah those
2012-06-09T18:38:05 < Laurenceb__> i see
2012-06-09T18:38:16 < Laurenceb__> so whats a reent struct?
2012-06-09T18:38:35 <+dekar> /newlib reent context
2012-06-09T18:38:36 <+dekar> struct _reent my_reent;         _REENT_INIT_PTR(&my_reent);
2012-06-09T18:39:21 < Laurenceb__> right
2012-06-09T18:39:22 <+dekar> if you do that it should be fully "thread safe"
2012-06-09T18:39:28 < Laurenceb__> oh i see
2012-06-09T18:41:53 <+dekar> I haven't fully implemented that for my firmware yet, but I plan on doing so

2012-06-09T23:47:25 < upgrdman> "interrupt vector" ... what's a vector?
2012-06-09T23:48:52 < zyp> function pointer, pretty much
2012-06-09T23:49:25 < upgrdman> ok
2012-06-09T23:49:36 < zyp> it points to the ISR, i.e. the function called when the interrupt is triggered
2012-06-09T23:50:12 < upgrdman> and that is specified to the linker, no in the source code, correct?
2012-06-09T23:54:02 < pelrun__> the link script specifies where the interrupt vectors are, and which function pointers should be loaded into them
2012-06-09T23:54:36 < pelrun__> then you just define a function with the appropriate name in the source
2012-06-09T23:55:57 < pelrun__> e.g. a function called "TIM3_IRQHandler" will be called whenever the TIM3 ISR is triggered

2012-06-10T00:26:19 < pelrun__> oh geez
2012-06-10T00:26:34 < pelrun__> my brain finally just realised why it's called 'thumb'
2012-06-10T00:27:04 < pelrun__> can't believe I didn't see that pun the instant it was made
2012-06-10T00:27:18 < zyp> :D
2012-06-10T00:27:32 < cjbaird> I'm punistically-challenged.
2012-06-10T00:28:00 < pelrun__> i annoy people incessantly with bad puns
2012-06-10T00:29:10 <+dekar> pelrun__, what's the pun you're talking about? arms as well as thumbs being body parts?
2012-06-10T00:29:29 < pelrun__> thumb being the small thing at the end of the arm
2012-06-10T00:29:40 <+dekar> yarr
2012-06-10T00:29:58 < pelrun__> THUMB being the small instruction set at the end of the ARM
2012-06-10T00:30:21 <+dekar> there's no end to ARM!
2012-06-10T00:33:05 < cjbaird> I honestly never realised that joke in 26 years...
2012-06-10T00:34:12 < zyp> thumb is just 18 years old
2012-06-10T00:35:53 < cjbaird> Well, I was just thinking of when I first heard of the Archimedes machines. I didn't think to think thumb appreared later..
2012-06-10T00:38:54 <+dekar> I just disassembled my firmware - the interrupt vector is just a bunch of addresses! I actually had a lecture about arm assembly (ARMv4) and they told us the interrupt vector contained the actual opcodes to jump into the handlers
2012-06-10T00:39:16 < zyp> it's different from architecture to architecture
2012-06-10T00:39:35 < zyp> IIRC AVR also have actual jump opcodes in the vector table
2012-06-10T00:40:04 <+dekar> was some old ATMEL ARM7-TDMI iirc
2012-06-10T00:44:53 < Laurenceb__> sup

2012-06-10T00:45:17 < Laurenceb__> lol i only just got that
2012-06-10T00:45:25 < Laurenceb__> i knew it was thumb as its small...
2012-06-10T00:46:15 < Laurenceb__> ok.. so i have TNT installed
2012-06-10T00:46:20 < Laurenceb__> where is the gcc to use?
2012-06-10T00:47:08 <+dekar> it installes into your home
2012-06-10T00:47:40 < Laurenceb__> aha ~/toolchain/bin$  ?
2012-06-10T00:47:49 <+dekar> yes
2012-06-10T00:49:40 <+dekar> cjbaird, TNT now compiles newlib with LTO for further space savings
2012-06-10T00:50:40 < Laurenceb__> /tmp/ccJeJXRp.s: Assembler messages:

2012-06-10T00:51:20 <+dekar> what they did is not allowed
2012-06-10T00:51:23 < Laurenceb__> what do i do?
2012-06-10T00:51:27 <+dekar> patch it
2012-06-10T00:51:38 <+dekar> I can give you mine if you want
2012-06-10T00:51:49 < Laurenceb__> core_cm3.s?
2012-06-10T00:51:52 <+dekar> but the CMSIS code is buggy
2012-06-10T00:51:53 <+dekar> yeah
2012-06-10T00:52:03 < Laurenceb__> k, pastebin?
2012-06-10T00:52:17 < Laurenceb__> odd that it works in codesourcery
2012-06-10T00:54:03 <+dekar> Laurenceb__, https://dl.dropbox.com/u/28467113/core_cm3.c
2012-06-10T00:54:22 <+dekar> Laurenceb__, old GCC didn't detect it - it is indeed illegal though, I looked it up
2012-06-10T00:54:25 < cjbaird> dekar: I'm about to attempt building TNT on the MIPS gNewsense machine..
2012-06-10T00:55:13 <+dekar> cjbaird, nice, but wouldn't it take ages on a mips? ;)
2012-06-10T00:55:24 <+dekar> I am not aware of any fast MIPS systems
2012-06-10T00:55:27 < Laurenceb__> ok thanks, that bit works
2012-06-10T00:55:41 < Laurenceb__> but     /toolchain/lib/gcc/arm-none-eabi/4.7.1/../../../../arm-none-eabi/bin/ld: cannot find libcs3.a
2012-06-10T00:56:07 <+dekar> libcs3 is codesourcery proprietary stuff
2012-06-10T00:56:15 <+dekar> they never even released the source code for that
2012-06-10T00:56:16 < Laurenceb__> oh
2012-06-10T00:56:20 < Laurenceb__> what does it do?
2012-06-10T00:56:28 < cjbaird> Don't diss my Lemote :P
2012-06-10T00:56:30 < Laurenceb__> equiv of newlib?
2012-06-10T00:56:42 < Laurenceb__> do i need to fix my linker script?
2012-06-10T00:56:43 <+dekar> handle some interrupts and some newlines stubs I think
2012-06-10T00:57:05 <+dekar> Laurenceb__ idk what pulls that libcs3 in
2012-06-10T00:57:18 < Laurenceb__> either makefile or linker script
2012-06-10T00:57:23 <+dekar> cjbaird, ah one of those illegal chinese mips? nice :)
2012-06-10T00:58:03 <+dekar> cjbaird, have you tried the x86er emulation features?
2012-06-10T00:58:27 < cjbaird> Wasn't aware of the Loongson2F having them..?
2012-06-10T00:58:39 <+dekar> cjbaird, it has 200 x86er opcodes iirc
2012-06-10T00:58:49 < Laurenceb__> oh shit
2012-06-10T00:58:58 < Laurenceb__> i have codesourcerys linker script
2012-06-10T00:58:58 < cjbaird> Yeah, it's the Loongson3 that has them.
2012-06-10T00:59:06 <+dekar> cjbaird, ah I see

2012-06-10T00:59:23 < Laurenceb__> anyone have a linker script that works with TNT?
2012-06-10T00:59:26 < cjbaird> I have plans of going /outside/ today, so I'll set the ~800MHz Lemote up to build TNT before I leave.
2012-06-10T00:59:39 < Laurenceb__> lol
2012-06-10T01:00:24 < Laurenceb__> anyone?
2012-06-10T01:02:37 <+dekar> Laurenceb__, https://dl.dropbox.com/u/28467113/stm32_linkerscript/TNT.zip
2012-06-10T01:03:06 < Laurenceb__> thanks
2012-06-10T01:03:15 < Laurenceb__> looks almost as complex as codesourcery :P
2012-06-10T01:04:31 <+dekar> we should make some tiny test project for TNT
2012-06-10T01:04:40 < zyp> I'll probably test TNT when I'm back from vacation and have started using my new workstation :p
2012-06-10T01:04:40 <+dekar> making it easier for beginners to start
2012-06-10T01:04:51 <+Steffanx> You still don't use it zyp ?!
2012-06-10T01:05:06 < zyp> no, I haven't bought a decent monitor yet
2012-06-10T01:05:06 <+dekar> zyp, it compiles reasonably fast, about an hour on my macbook
2012-06-10T01:05:29 <+Steffanx> I'm pretty sure it was faster on mine .. but perhaps i was wrong
2012-06-10T01:05:33 <+Steffanx> *was = am
2012-06-10T01:05:39 < zyp> dekar, yeah, but I'm not in a hurry to test it
2012-06-10T01:06:02 < zyp> my project, when compiled with yagarto, is still only 7k or so :p
2012-06-10T01:06:12 < zyp> and that's for F4 with 1M flash :p
2012-06-10T01:06:17 <+dekar> zyp, could be 6kb with TNT :P
2012-06-10T01:06:20 <+Steffanx> And hw fp stuff?
2012-06-10T01:06:37 <+dekar> Steffanx, I actually think TNT supports hw float stuff
2012-06-10T01:06:46 <+dekar> haven't tried it though
2012-06-10T01:06:47 < zyp> dekar, I don't really think it would make a huge difference
2012-06-10T01:06:49 <+Steffanx> think != being sure
2012-06-10T01:07:00 < zyp> dekar, we could check
2012-06-10T01:07:13 <+dekar> Steffanx, I managed to have it generate some float code once, which made my stm32f1 lock up
2012-06-10T01:07:25 <+dekar> didn't look into it though
2012-06-10T01:07:35 < zyp> dekar, git://git.jvnv.net/suzumebachi <- grab stm32f4 branch from here and just run scons
2012-06-10T01:07:39 <+dekar> Steffanx, if you care, feel free to disassemble
2012-06-10T01:07:45 <+Steffanx> No thanks
2012-06-10T01:07:59 <+dekar> what's scons?
2012-06-10T01:08:07 < zyp> a decent make alternative
2012-06-10T01:09:25 <+dekar> I probably need to have TNT in path, don't I?
2012-06-10T01:09:38 < cjbaird> ...one of several dozen, which everyone expects you to learn..
2012-06-10T01:09:54 < zyp> dekar, yes
2012-06-10T01:10:00 <+Steffanx> Just edit the sconstruct file
2012-06-10T01:10:08 < cjbaird> It's as annyoing as people who publish code written in Modula2. :P

2012-06-10T01:10:26 <+Steffanx> I've no idea what something like that means

2012-06-10T01:10:37 <+dekar> scons: done building target.
2012-06-10T01:10:42 <+Steffanx> oops
2012-06-10T01:10:44 <+Steffanx> me failing
2012-06-10T01:11:02 <+dekar> Steffanx, linking binary stuff?
2012-06-10T01:11:32 <+Steffanx> nvm.. wrong combination of toolchains :P
2012-06-10T01:11:32 <+dekar> zyp, so what do I do now?
2012-06-10T01:11:38 <+dekar> it did build
2012-06-10T01:11:48 < zyp> then check the size? :p
2012-06-10T01:12:00 < Laurenceb__> ok it compiles
2012-06-10T01:12:01 < Laurenceb__> thanks
2012-06-10T01:12:09 < Laurenceb__> only 14% smaller
2012-06-10T01:12:12 <+Steffanx> only?

2012-06-10T01:12:43 < zyp> hmm, I commented out gc-sections once I was debugging some issue

2012-06-10T01:12:47 <+dekar> zyp, I didn't use LTO though, didn't look at your scons file

2012-06-10T01:12:58 < zyp> is that unchanged?
2012-06-10T01:13:00 < Laurenceb__> etc  ?
2012-06-10T01:13:10 <+dekar> zyp, didn't change anything

2012-06-10T01:13:45 < zyp> I get it a bit smaller with -Os and gc-sections, but still not as small as TNT

2012-06-10T01:14:05 <+dekar> zyp, want me to enable LTO?
2012-06-10T01:14:07 < Laurenceb__> ok - i used wrong flags
2012-06-10T01:14:12 < zyp> dekar, sure
2012-06-10T01:14:13 < Laurenceb__> 29% smaller
2012-06-10T01:14:21 < zyp> SConscript should be pretty understandable
2012-06-10T01:14:28 < Laurenceb__> than codesourcery
2012-06-10T01:14:29 < zyp> SConstruct I mean :p
2012-06-10T01:14:53 < Laurenceb__> how do i do LTO?
2012-06-10T01:14:58 < Laurenceb__> wouls that help?
2012-06-10T01:15:22 <+Steffanx> A little maybe
2012-06-10T01:15:45 < zyp> so, for my project TNT shaves off 32% of the size
2012-06-10T01:15:50 < zyp> that was kind of unexpected
2012-06-10T01:16:29 <+Steffanx> :D
2012-06-10T01:16:38 <+Steffanx> but does it still work
2012-06-10T01:16:40 <+Steffanx> ?
2012-06-10T01:16:48 < zyp> that's another question :p
2012-06-10T01:16:48 <+dekar> zyp, how do I "make clean"?
2012-06-10T01:16:53 < zyp> scons -c
2012-06-10T01:17:07 < Laurenceb__> i see 29% smaller on my project

2012-06-10T01:17:25 < Laurenceb__> without trying LTO.. how would i do that?
2012-06-10T01:17:26 <+dekar> that looks wrong
2012-06-10T01:17:30 < Laurenceb__> wtf
2012-06-10T01:17:31 < Laurenceb__> lol
2012-06-10T01:17:32 < zyp> ha
2012-06-10T01:17:33 <+dekar> XD
2012-06-10T01:17:42 <+dekar> zyp, I did also enable gc-sections
2012-06-10T01:17:48 <+dekar> was that correct?
2012-06-10T01:17:52 <+dekar> dunno your project
2012-06-10T01:17:56 < zyp> hmm
2012-06-10T01:18:12 < zippe> dekar: is your project "complete", or have you #ifdef'ed out large parts?
2012-06-10T01:18:14 <+dekar> I guess LTO dropped some entry points or something
2012-06-10T01:18:22 < zippe> Or just the calls to large parts?
2012-06-10T01:18:30 < zippe> You do need to mark the vectors section to be kept
2012-06-10T01:18:31 < zyp> dekar, can you send me the .elf?
2012-06-10T01:18:36 <+dekar> zippe, what are you talking about?
2012-06-10T01:18:38 < zippe> It's common to lose everything if you forget that
2012-06-10T01:18:40 <+dekar> zyp, sure
2012-06-10T01:18:49 <+Steffanx> sure you are using the stm32f4 branch dekar ?
2012-06-10T01:18:50 < zyp> dekar, just put it on bin.jvnv.net or something
2012-06-10T01:19:10 < zippe> If you don't have a separate section for your vectors, you can
2012-06-10T01:19:11 < zippe> EXTERN(_vectors)	/* force the vectors to be included in the output */
2012-06-10T01:19:19 <+dekar> zyp, https://dl.dropbox.com/u/28467113/suzumebachi.zip
2012-06-10T01:19:23 < zyp> thanks
2012-06-10T01:19:44 < zyp> looking forward to see the disassembly :p
2012-06-10T01:19:52 <+dekar> zippe, it's not my project but the project of zyp
2012-06-10T01:20:15 <+dekar> zippe, dunno what it does, keeps or drops
2012-06-10T01:20:17 < Laurenceb__> so, how can i use LTO?
2012-06-10T01:21:02 < zyp> dekar, it fucked up the vector table at least
2012-06-10T01:21:15 < zyp> no vector table at the start
2012-06-10T01:21:22 < Laurenceb__> oops

2012-06-10T01:21:49 <+dekar> zyp, probably your linkerscript
2012-06-10T01:22:00 < zyp> dekar, oh, and wrong branch
2012-06-10T01:22:12 < zyp> that's the master branch, not stm32f4
2012-06-10T01:22:41 <+dekar> oh
2012-06-10T01:22:52 <+dekar> well, compile TNT yourself :P
2012-06-10T01:23:07 < zyp> :p
2012-06-10T01:23:51 < zyp> ha
2012-06-10T01:24:12 < Laurenceb__> ok it tries to optimise.. but fails
2012-06-10T01:24:23 < zyp> dekar, I switched to master and recompiled

2012-06-10T01:26:09 <+dekar> zyp, first time was -O2
2012-06-10T01:26:13 <+dekar> did you -O2 as well?
2012-06-10T01:26:20 <+dekar> your "makefile" came with -O2
2012-06-10T01:26:25 < zyp> yes, this was unchanged
2012-06-10T01:26:47 <+dekar> not bad then I guess
2012-06-10T01:27:23 < zyp> but then I don't really link in much from newlib
2012-06-10T01:28:01 < zyp> maybe some libm functions, but I'm not sure they are present in that revision
2012-06-10T01:29:35 < Laurenceb__> http://pastebin.com/1cu08DCy   <-- can anyone advise me what the issue is?
2012-06-10T01:30:22 <+dekar> zyp,    text    data     bss     dec     hex filename
2012-06-10T01:30:22 <+dekar>    3396     564    5800    9760    2620 suzumebachi.elf
2012-06-10T01:30:34 <+dekar> without LTO, but with -Os and gc-sections
2012-06-10T01:30:47 < zyp> for which branch? :p
2012-06-10T01:30:50 < zyp> still master?
2012-06-10T01:30:53 <+dekar> zyp, same as before
2012-06-10T01:30:55 <+dekar> yeah
2012-06-10T01:30:58 < zyp> ok
2012-06-10T01:31:27 < zyp>    text	   data	    bss	    dec	    hex	filename
2012-06-10T01:31:27 < zyp>    3380	   1400	   5800	  10580	   2954	suzumebachi.elf
2012-06-10T01:32:21 <+dekar> zyp, text+data is now smaller for me
2012-06-10T01:32:27 < zyp> :p
2012-06-10T01:32:35 < zyp> wonder what's different
2012-06-10T01:32:42 <+dekar> well I guess -O2 cares more about speed than size
2012-06-10T01:32:47 < zyp> yes
2012-06-10T01:33:12 < zyp> -Os is -O2 without a couple of optimizations that add size
2012-06-10T01:33:23 <+dekar> and given that TNT has a newer GCC than YAG… I guess it makes sense that TNT wins
2012-06-10T01:33:51 <+dekar> zyp, do you want the binary so you can try whether it works?
2012-06-10T01:34:31 <+dekar> zyp, https://dl.dropbox.com/u/28467113/suzumebachi.zip
2012-06-10T01:34:35 < zyp> nah, I don't have the F1 setup for a quick test
2012-06-10T01:34:39 <+dekar> hm
2012-06-10T01:34:53 <+dekar> zyp, do you have the f4 ready?
2012-06-10T01:35:52 <+dekar> well w/e
2012-06-10T01:36:02 < zyp> I do, but it's not that important
2012-06-10T01:36:11 < zyp> hmm
2012-06-10T01:36:33 < zyp> my project's object files only contains 324 bytes of .data
2012-06-10T01:36:38 < Laurenceb__> http://pastebin.com/1cu08DCy   <-- hellooo  can anyone advise me what the issue is?

2012-06-10T01:36:47 < Laurenceb__> seems to be missing _exit
2012-06-10T01:36:49 < zyp> so something in newlib adds over 1k in data
2012-06-10T01:37:08 < zyp> so it's not my fault :p
2012-06-10T01:37:22 < zyp> Laurenceb__, try -lnosys
2012-06-10T01:37:29 <+dekar> zyp, well TNT has some finely tuned newlib for minimum size
2012-06-10T01:37:34 < Laurenceb__> in LDFLAGS  ?
2012-06-10T01:37:43 < zyp> Laurenceb__, yes, it's a library

2012-06-10T01:38:11 < Laurenceb__> oh
2012-06-10T01:38:40 <+dekar> Laurenceb__ those are newlib stubs, codesourcery had them partially implemented
2012-06-10T01:38:49 -!- FUZxxl [~fuz@no.spaceleft.net] has joined ##stm32
2012-06-10T01:38:59 < Laurenceb__> ok

2012-06-10T01:39:20 < Laurenceb__> is there a whole series of things im missing now?
2012-06-10T01:39:47 < zyp> Laurenceb__, are you linking with gc-sections?
2012-06-10T01:39:49 <+dekar> Laurenceb__ that discarded section looks wrong
2012-06-10T01:40:09 <+dekar> Laurenceb__ does it work without LTO for you?
2012-06-10T01:40:17 < Laurenceb__> yes
2012-06-10T01:40:19 <+dekar> k
2012-06-10T01:40:26 < Laurenceb__> compiles fine without LTO, 29% smaller
2012-06-10T01:41:06 < Laurenceb__> what are gc-sections?
2012-06-10T01:41:28 <+dekar> Laurenceb__ discard unused sections
2012-06-10T01:41:52 < Laurenceb__> oh
2012-06-10T01:42:12 < Laurenceb__> ok i removed --gc-sections from the makefile, it got a biut further before breaking
2012-06-10T01:42:31 <+dekar> Laurenceb__ you shouldn't have to remove it
2012-06-10T01:42:32 < Laurenceb__> wait no
2012-06-10T01:42:37 < Laurenceb__> it broke earlier
2012-06-10T01:43:11 < Laurenceb__> hmm
2012-06-10T01:43:40 <+dekar> do you have any assembly for example?
2012-06-10T01:43:51 < Laurenceb__> from what?
2012-06-10T01:44:01 <+dekar> LTO doesn't read assembly and might drop stuff that is actually called
2012-06-10T01:44:18 < Laurenceb__> oh
2012-06-10T01:44:28 < Laurenceb__> libc.a is linked
2012-06-10T01:44:37 <+dekar> you may wanna try marking your interrupt handlers (entry points) with "__attribute__((externally_visible))"
2012-06-10T01:44:47 < zyp> doesn't LTO pass GIMPLE rather than assembly to the linker?
2012-06-10T01:45:21 <+dekar> zyp, both actually
2012-06-10T01:45:38 <+dekar> zyp, LTO makes your .o files size increase like 5 times
2012-06-10T01:46:00 < zyp> sure, because they are stored in intermediate (GIMPLE) form
2012-06-10T01:46:06 <+dekar> Laurenceb__, try removing the whole-program flag
2012-06-10T01:46:21 < Laurenceb__> what is that?
2012-06-10T01:46:41 <+dekar> that makes LTO be more aggressive and drop everything not being referenced
2012-06-10T01:46:45 < Laurenceb__> in the makefile
2012-06-10T01:46:46 < Laurenceb__> oh
2012-06-10T01:47:22 <+dekar> stuff that is referenced from assembly is also dropped (was for me at least)
2012-06-10T01:47:40 < Laurenceb__> no luck there
2012-06-10T01:47:41 <+dekar> since 'as' doesn't support LTO
2012-06-10T01:47:50 < Laurenceb__> ill pastebin my makefile
2012-06-10T01:47:54 < Laurenceb__> its a mess, sorry
2012-06-10T01:48:07 < zyp> most makefiles are :D
2012-06-10T01:48:19 < Laurenceb__> http://pastebin.com/XEzWpTG3
2012-06-10T01:48:19 <+dekar> idk why it drops impure, that's the pointer for the newlib reentrancy context
2012-06-10T01:48:26 < Laurenceb__> thanx for the help
2012-06-10T01:49:27 <+dekar> removing "-fwhole-program" didn't help?
2012-06-10T01:49:32 < Laurenceb__> nope
2012-06-10T01:49:44 < Laurenceb__> i removed it than made clean
2012-06-10T01:49:52 < Laurenceb__> make clean; make
2012-06-10T01:51:33 <+dekar> Laurenceb__, http://pastebin.com/uUdPSCrc
2012-06-10T01:51:36 <+dekar> add that to your main
2012-06-10T01:51:44 <+dekar> make the struct global
2012-06-10T01:52:04 <+dekar> that uses the impure pointer, maybe it stops it from getting discarded
2012-06-10T01:53:30 < Laurenceb__> wont compile - redeclaration
2012-06-10T01:53:56 <+dekar> umm what?
2012-06-10T01:54:13 <+dekar> what in global namespace "struct _reent my_reent;"
2012-06-10T01:54:17 <+dekar> *that
2012-06-10T01:54:28 <+dekar> that into your main() "_REENT_INIT_PTR(&my_reent);

2012-06-10T01:55:08 < Laurenceb__> wait what
2012-06-10T01:55:13 < Laurenceb__> that makes no sense
2012-06-10T01:55:38 <+dekar> the code I pasted doesn't declare _impure_ptr
2012-06-10T01:55:45 < Laurenceb__> exactly
2012-06-10T01:56:02 <+dekar> it just assigns it
2012-06-10T01:56:18 < Laurenceb__> my mistake
2012-06-10T01:56:20 <+dekar> something is pretty fucked up XD
2012-06-10T01:57:19 < Laurenceb__> ok

2012-06-10T01:58:20 < Laurenceb__> thanks for the help
2012-06-10T01:59:08 <+dekar> Laurenceb__ it still doesn't work, does it?
2012-06-10T01:59:53 <+dekar> idk what section .init is
2012-06-10T01:59:57 <+dekar> or where it comes from
2012-06-10T02:01:12 <+dekar> Laurenceb__ open the sections_FLASH.ld
2012-06-10T02:01:24 <+dekar> search for "/DISCARD/"
2012-06-10T02:01:45 <+dekar> and add *(.init*) to the list
2012-06-10T02:02:03 <+dekar> Laurenceb__ whatever that .init section is, that should kill it
2012-06-10T02:02:16 <+dekar> flyback, what did you ask?
2012-06-10T02:03:21 < Laurenceb__> `_init' referenced in section `.text' of /tmp/ccarQpEv.ltrans7.ltrans.o: defined in discarded section `.init' of /home/laurence/toolchain/lib/gcc/arm-none-eabi/4.7.1/thumb/crti.o
2012-06-10T02:03:47 < Laurenceb__> isnt .init the startup code?
2012-06-10T02:04:48 <+dekar> Laurenceb__, wait
2012-06-10T02:04:54 <+dekar> let me look at your makefile
2012-06-10T02:05:09 <+dekar> Laurenceb__: add -nostartfiles to LDFLAGS
2012-06-10T02:06:04 < Laurenceb__> bbl
2012-06-10T02:06:36 <+dekar> Laurenceb__, before you leave try what I told you
2012-06-10T02:07:47 <+dekar> flyback, big companies suck
2012-06-10T02:07:56 <+dekar> it's always the same with them
2012-06-10T02:09:18 <+dekar> flyback, I once lost my phoneline/ISP contract over crap like that
2012-06-10T02:12:35 <+dekar> it went like… me: "why did you charge my bank account, I didn't get any service yet!" they: "you can look at the invoice online, you just have to login…" me: "how do I do that without internet?" they: "why do you order internet if you don't have a PC?" me: "wtf? My PC is fine, your company didn't connect my service yet!" they: "that's impossible, I can see in my computer that your internet is working fine!"
2012-06-10T02:13:20 <+dekar> -> I canceled the charges from my bank account and they cancelled my contract
2012-06-10T02:13:50 <+dekar> they still want money from me, I wonder whether I'll see them in court
2012-06-10T02:26:04 < zyp> how can you not have internet access in 2012? :p
2012-06-10T02:27:58 <+dekar> I have internet
2012-06-10T02:28:03 <+dekar> just not the DSL I wanted
2012-06-10T02:28:19 < zyp> how can somebody want DSL in 2012? :p
2012-06-10T02:30:14 <+dekar> VDSL is quite epic
2012-06-10T02:30:23 <+dekar> 50mbit/s down and 10mbit/s up
2012-06-10T02:30:53 <+dekar> cable only has 5mbit/s up here
2012-06-10T02:31:18 <+dekar> zyp, what do you get at your place?
2012-06-10T02:32:29 < zyp> I currently have 70/10 on cable
2012-06-10T02:32:43 < zyp> and I'm sorry, I read DSL as ADSL
2012-06-10T02:32:57 < zyp> my bashing was intended for ADSL
2012-06-10T02:33:58 <+dekar> I actually don't even care for speed that much
2012-06-10T02:34:09 <+dekar> I guess 10mbit/s would be enough
2012-06-10T02:34:43 <+dekar> I do like upload though
2012-06-10T02:34:51 < zyp> yeah, I had 20/5 last year
2012-06-10T02:35:06 < zyp> jumped at an offering for 50/10 at same cost around newyears
2012-06-10T02:35:15 < zyp> and then that got upgraded to 70/10
2012-06-10T02:36:20 < zyp> I had 10/10 for three years before I moved last summer
2012-06-10T02:36:42 < zyp> going 10 -> 20 down were a nice boost, and 10 -> 5 up weren't really noticeable
2012-06-10T02:37:12 < zyp> beyond 20 down, I haven't really noticed a huge difference
2012-06-10T02:38:00 < zyp> small downloads are only a few minutes either way, and huge downloads still take enough time that I forget about them before they finish
2012-06-10T02:46:32 < Laurenceb__> back
2012-06-10T02:46:53 < Laurenceb__> with nostartfiles i get the _impure_ptr error again

2012-06-10T03:34:25 < dongs> im still waiting for that guy to email me what practical application is there for propeller other than academic wank
2012-06-10T03:34:39 < dongs> can any of you dudes think of one
2012-06-10T03:35:15 < zyp> honestly, no trolling? not really
2012-06-10T03:35:22 < dongs> ya, honestly no trolling
2012-06-10T03:35:41 < dongs> from what I understand it has zero useful peripherals
2012-06-10T03:35:54 < zyp> it's parallax, after all
2012-06-10T03:35:55 < dongs> practically no memory per cog and a cog can only access its own memory
2012-06-10T03:36:20 < dongs> 160mips over 8 cores parallel isn't all that impressive calculation-wise.
2012-06-10T03:36:53 < zyp> nah
2012-06-10T03:37:13 < zyp> and then there is the «spin» stuff
2012-06-10T03:37:48 < dongs> right
2012-06-10T03:37:57 < dongs> the other multicore shit, xmos, can at least be programmed in regular C
2012-06-10T03:38:09 < dongs> though it sucks just as bad wrt periperals etc.
2012-06-10T03:38:42 < zyp> I looked at xmos recently, it's very different from the propeller
2012-06-10T03:39:14 < zyp> and actually seems pretty good for what it does
2012-06-10T03:40:59 < zyp> dongs, but yeah, I see the propeller as some «modern» variant of the basic stamp
2012-06-10T03:41:18 < dongs> heh
2012-06-10T03:41:37 < zyp> since it's all parallax
2012-06-10T03:41:40 < dongs> but basic stamp is at least usable
2012-06-10T03:41:41 < dongs> right
2012-06-10T03:41:49 < zyp> so that was probably the intention
2012-06-10T03:41:54 < dongs> to me, the fact that it s till comes in dip package automatically discredits it
2012-06-10T03:42:13 < dongs> btw i think the new hobbyking "32bit" flyingthing uses prop lol
2012-06-10T03:42:21 < zyp> is basic stamp any more usable than the propeller?
2012-06-10T03:42:26 < dongs> yes
2012-06-10T03:42:31 < zyp> how?
2012-06-10T03:42:41 < dongs> people actually understand basic
2012-06-10T03:42:49 < dongs> and they dont need to worry about concurrency and shit
2012-06-10T03:43:02 < dongs> ive seen lots of dumb hacks done on basicstamp because its easy
2012-06-10T03:43:06 < dongs> prop would be a huge learning curve
2012-06-10T03:43:23 < dongs> http://a.yfrog.com/img815/3193/ca4bi.jpg
2012-06-10T03:43:25 < dongs> what do you think
2012-06-10T03:43:30 < zyp> 02:43:02 < dongs> ive seen lots of dumb hacks done on basicstamp because its easy
2012-06-10T03:43:32 < dongs> props?
2012-06-10T03:43:33 < zyp> sounds like arduino
2012-06-10T03:43:48 < dongs> im not aware of any ARM proc in 44tqfp
2012-06-10T03:44:44 < dongs> i searched 'cortex' on digikey and scrolled through package list and nothing was in 44tqfp
2012-06-10T03:48:09 < zyp> looks like atmel logo or something on the chips
2012-06-10T03:48:12 < dongs> pretty sure no arm exists in dip
2012-06-10T03:48:15 < dongs> zyp: thats what im thinking
2012-06-10T03:48:25 < dongs> 44tqfp is atmel's package too
2012-06-10T03:48:35 < dongs> that thin one
2012-06-10T03:49:26 < zyp> flyback, way to be irrelevant
2012-06-10T03:49:47 < dongs> lol dip28
2012-06-10T03:52:58 < zyp> yeah, let's use packages that's longer than my entire F4 board
2012-06-10T03:54:08 < dongs> hobbyists stuck in 1996 maybe
2012-06-10T03:54:17 < dongs> hobbyists in 2012 can do bga shit at home
2012-06-10T03:54:33 < cjbaird> Breadboard people
2012-06-10T03:54:44 < dongs> yes really
2012-06-10T03:55:05 < TheSeven> hobbyists would happily use some LQFP packages in DIP-whatever adapters :P
2012-06-10T03:55:24 < cjbaird> Maybe if you're some hikki who has nothing better to do than design and order boards from PCB shops..
2012-06-10T03:57:41 < dongs> i geuss nobody ever said hk-kk2 was 32bit. people jut assumed
2012-06-10T03:57:46 < dongs> so its probably just a fucking mega644 or some other trash
2012-06-10T03:57:47 < dongs> pass.
2012-06-10T04:00:13 < cjbaird> Someone I remember from the original NXP DIP28 announcements was it really being intended for the ultra-cheap production types, who do single/double sided PCB products. (Hand-etched by indentured slave kids in India..)
2012-06-10T04:01:16 < dongs> if its not on digikey, it doesnt exist

2012-06-10T09:29:24 < upgrdman_> what lib are you using for char lcd?
2012-06-10T09:31:46 < GargantuaSauce> i ported the arduino code from http://spikenzielabs.com/SpikenzieLabs/I2C-SPI_LCD.html
2012-06-10T09:32:08 < GargantuaSauce> it's pretty bad though, need to refactor it entirely now that i have a working baseline
2012-06-10T09:32:53 < upgrdman_> i wonder if it would be hard to wite one from scratch. i might try it just to learn.
2012-06-10T09:33:17 < GargantuaSauce> using chibios underneath...nice to have blocking functions for sending and receiving
2012-06-10T09:33:33 < GargantuaSauce> Wire is fucking garbage, i am never going to do anything significant on the arduino again
2012-06-10T09:33:43 < upgrdman_> do you know if a 5v lcd will work on 3v and 3v logic?
2012-06-10T09:34:03 < GargantuaSauce> doubtful

2012-06-10T09:36:09 < GargantuaSauce> especially not for i2c, since it's an open drain thing
2012-06-10T09:36:20 < GargantuaSauce> just pull up to 5v and it will work, exactly like my pic
2012-06-10T09:36:49 < GargantuaSauce> (those are 500 ohm resistors, 2 in series...increasing by an order of magniude would be a good idea though

2012-06-10T14:02:51 < Laurenceb__> thats a 34% reduction
2012-06-10T14:04:13 < Laurenceb__> but this doesnt look right atm
2012-06-10T14:04:17 < Laurenceb__> at least it compiles

2012-06-10T14:31:24 < Laurenceb__> i had issues with .init and .fini sections
2012-06-10T14:31:31 < Laurenceb__> any idea where they go?
2012-06-10T14:32:14 < dongs> nope? i dont dick around with linker scripts

2012-06-10T14:40:42 < cjbaird> they grow on trees?
2012-06-10T14:40:49 < dongs> lewl
2012-06-10T14:42:42 < cjbaird> I used chopsticks on the around-Australia motorbike trip: they're pretty useful for camping, actually.
2012-06-10T14:42:51 <+dekar> cjbaird, did you use LTO to compile the mandelbrot?
2012-06-10T14:46:36 < cjbaird> Yep. Code was ~1.5kB/5% smaller.
2012-06-10T14:46:54 < cjbaird> Well, by LTO, you mean the TNT toolchain?
2012-06-10T14:47:09 <+dekar> cjbaird, you have to set special flags for LTO
2012-06-10T14:47:30 <+dekar> TNT supports LTO and normal compile time optimizations
2012-06-10T14:47:44 <+dekar> LTO is usually superior though
2012-06-10T14:49:41 <+dekar> CFLAGS += -flto -fuse-linker-plugin LDFLAGS += -flto -fuse-linker-plugin -fwhole-program
2012-06-10T14:50:04 <+dekar> cjbaird, oh and make sure to add -Os to _LDFLAGS_ as well

2012-06-10T14:50:21 < Laurenceb__> im getting it to build now
2012-06-10T14:50:23 <+dekar> since with LTO the linker optimizes and not the compiler
2012-06-10T14:50:41 < Laurenceb__> still doesnt look quite right, need to fix the linker script
2012-06-10T14:50:53 < Laurenceb__> down to 70KB from 113
2012-06-10T14:51:26 <+dekar> Laurenceb__, what's that insanely huge project you have?
2012-06-10T14:51:42 < Laurenceb__> its a datalogger
2012-06-10T14:52:20 <+dekar> ah I remember that one
2012-06-10T14:52:22 < Laurenceb__> datalogger with fat32+usb mass storage+led based "spectrometer"+various pneumatics stuff
2012-06-10T14:54:27 < Laurenceb__> ive got an autopilot project too, but havent really worked on it for a while
2012-06-10T14:54:42 < Laurenceb__> it could benefit from shrinking, as atm it only just fits into 128KB
2012-06-10T14:55:50 < Laurenceb__> clive1 seems to know what hes talking about
2012-06-10T14:56:36 < zyp> what's the issue?
2012-06-10T14:56:49 < Laurenceb__> .init and .fini
2012-06-10T14:57:20 < zyp> somebody here mentioned that gold doesn't respect KEEP in linker scripts
2012-06-10T14:57:29 < zyp> so that might be the issue
2012-06-10T14:57:44 <+dekar> zyp, he's not using gold
2012-06-10T14:57:57 < zyp> doesn't LTO require gold?

2012-06-10T15:00:13 < Laurenceb__> no, just .init, .fini

2012-06-10T15:00:47 <+dekar> well my code doesn't have those sections
2012-06-10T15:00:50 < zyp> I haven't seen my compiler emitting them, but I would guess that's where the actual init/fini methods are emitted then
2012-06-10T15:01:03 < zyp> I believe my compiler throws them into .text
2012-06-10T15:01:15 <+dekar> Laurenceb__, what's your startup code?

2012-06-10T15:11:15 < Laurenceb__> but wtf is  andcs   r0, r1, r0
2012-06-10T15:11:16 <+dekar> 0x20010000 is your stack
2012-06-10T15:11:19 < zyp> my linker script only exposes the symbols expected by my startup code, so it won't work with any other startup code
2012-06-10T15:11:35 <+dekar> Laurenceb__, don't read the disassembly for the interrupt vector lol
2012-06-10T15:11:36 < zyp> Laurenceb__, it's what it would be if it were an instruction
2012-06-10T15:11:48 < Laurenceb__> oh lmao
2012-06-10T15:12:25 < Laurenceb__> i see
2012-06-10T15:15:22 <+dekar> Laurenceb__, did you ever call .fini/.init from your old code?
2012-06-10T15:15:46 < Laurenceb__> no
2012-06-10T15:16:20 <+dekar> so your global objects weren't constructed at startup?
2012-06-10T15:16:45 < zyp> if he have any
2012-06-10T15:17:04 < Laurenceb__> http://pastie.org/4061334
2012-06-10T15:17:05 <+dekar> zyp, if he doesn't he should be able to drop them anyway
2012-06-10T15:17:37 <+dekar> [14:07]  <dekar> Laurenceb__, what's at 0x08008ff9?
2012-06-10T15:17:43 < Laurenceb__> sec
2012-06-10T15:17:57 < zyp> hmm, interesting
2012-06-10T15:18:04 < zyp> oh
2012-06-10T15:18:05 < zyp> haha
2012-06-10T15:18:12 < zyp> those are empty functions
2012-06-10T15:18:40 < Laurenceb__> 08008ff8 <Reset_Handler>:
2012-06-10T15:18:40 < Laurenceb__>  8008ff8:	2100      	movs	r1, #0
2012-06-10T15:18:40 < Laurenceb__>  8008ffa:	f000 b804 	b.w	8009006 <LoopCopyDataInit>
2012-06-10T15:19:07 < zyp> creates a stack frame and destroys it again
2012-06-10T15:19:23 < zyp> those can safely be dropped
2012-06-10T15:19:29 < Laurenceb__> ok
2012-06-10T15:19:59 < Laurenceb__> does the reset hander look sane?
2012-06-10T15:20:43 < zyp> https://dl.dropbox.com/u/28467113/startup_stm32f10x_hd.s <- sure, it corresponds exactly to this
2012-06-10T15:21:06 < Laurenceb__> why are all the vectors odd?
2012-06-10T15:21:14 < zyp> thumb
2012-06-10T15:21:24 < zyp> lower bit selects thumb or arm mode
2012-06-10T15:21:26 <+dekar> Laurenceb__, they're not actually odd
2012-06-10T15:22:04 < Laurenceb__> ah yeah i remember
2012-06-10T15:22:07 < Laurenceb__> makes sense
2012-06-10T15:22:07 < zyp> every instruction have to be 16-bit aligned, so lower bit is not used for adressing
2012-06-10T15:22:20 < zyp> so they put a flag there instead
2012-06-10T15:22:23 < Laurenceb__> cool, ill have to try running this tomorrow
2012-06-10T15:22:55  * Laurenceb__ is watching balloons on spacenear
2012-06-10T15:23:12 <+dekar> I like how _init and _fini do NOP :)
2012-06-10T15:23:19 < zyp> it's kind of intel and their pagetables on x86
2012-06-10T15:23:32 < zyp> every page is 4k, so every page addr is 4k aligned
2012-06-10T15:23:41 < zyp> so they have 12 bits free to use for flags
2012-06-10T15:25:46 < Laurenceb__> 35% size reduction isnt bad then :P
2012-06-10T15:26:42 <+dekar> I have seen TNT do as much before
2012-06-10T15:27:05 <+dekar> Laurenceb__, http://pastebin.com/uJUe7rbX
2012-06-10T15:27:49 < Laurenceb__> nice
2012-06-10T15:28:34 < Laurenceb__> malloc should be better behaved too
2012-06-10T15:29:00 <+dekar> yeah

2012-06-10T17:46:54 < Laurenceb__> my interrupts are all broken :-/
2012-06-10T17:47:27 < Laurenceb__> well apart from <ADC1_2_IRQHandler>
2012-06-10T17:49:26 <+dekar> Laurenceb__, hahaha
2012-06-10T17:49:40 < Laurenceb__> it obviously the names
2012-06-10T17:49:50 < Laurenceb__> but i see them in the COMMON linker
2012-06-10T17:49:53 < Laurenceb__> im confused
2012-06-10T17:50:03 <+dekar> LTO did that
2012-06-10T17:50:11 <+dekar> umm prefix them with "__attribute__((externally_visible))"
2012-06-10T17:50:38 < Laurenceb__> oh
2012-06-10T17:50:50 < Laurenceb__> i had this issue before with typos in linker scripts
2012-06-10T17:51:21 < Laurenceb__> void __attribute__((externally_visible))   IRQ_Handler   ?
2012-06-10T17:52:02 <+dekar> left of the void
2012-06-10T17:59:17 < Laurenceb__> ok, its grown a bit in size and the handers are there
2012-06-10T17:59:34 < Laurenceb__> but shouldnt the addresses be at the start in the vectors?
2012-06-10T17:59:39 <+dekar> you can also pass "-u function-name" to the linker
2012-06-10T18:00:02 <+dekar> yes they should
2012-06-10T18:00:42 < Laurenceb__> hmm
2012-06-10T18:00:54 < Laurenceb__> only the reset hander and the adc handers are there
2012-06-10T18:01:07 <+dekar> did you prefix them?
2012-06-10T18:01:10 < Laurenceb__> yes
2012-06-10T18:01:12 <+dekar> the other ones I mean?
2012-06-10T18:01:16 < Laurenceb__> yes
2012-06-10T18:01:17 <+dekar> didn't help?
2012-06-10T18:01:21 < Laurenceb__> it did yes
2012-06-10T18:01:28 < Laurenceb__> all the hander functions are now in the asm
2012-06-10T18:01:40 < Laurenceb__> but they arent all in the vector table
2012-06-10T18:01:50 <+dekar> what's in the vector then?
2012-06-10T18:01:55 <+dekar> just zero?
2012-06-10T18:03:01 < Laurenceb__> 08009e8c <BusFault_Handler>:
2012-06-10T18:03:02 < Laurenceb__> lol
2012-06-10T18:03:29 < Laurenceb__> lots of busfault
2012-06-10T18:03:33 <+dekar> give me a name of some dropped handler
2012-06-10T18:03:46 <+dekar> I remember codesourcery had different names for them
2012-06-10T18:03:50 <+dekar> maybe that's the problem
2012-06-10T18:04:14 < Laurenceb__> DMAChannel1_IRQHandler
2012-06-10T18:04:25 < Laurenceb__> yes, but i see that name in the COMMON linker
2012-06-10T18:04:42 < Laurenceb__> PROVIDE (   DMAChannel1_IRQHandler = 0 ) ;
2012-06-10T18:04:59 <+dekar> Laurenceb__, rename it to DMA1_Channel1_IRQHandler
2012-06-10T18:05:55 <+dekar> Laurenceb__, https://dl.dropbox.com/u/28467113/startup_stm32f10x_hd.s
2012-06-10T18:06:02 <+dekar> look the names up in the startup code
2012-06-10T18:06:12 < Laurenceb__> oh
2012-06-10T18:06:37 < Laurenceb__> so confusing
2012-06-10T18:07:09 <+dekar> XD
2012-06-10T18:08:31 < jon1012> (whoeve told me enc28j60 wsasn't fitted was right :))
2012-06-10T18:09:14 < jon1012> (max data rate I get is 100k / s...)
2012-06-10T18:12:51 < Laurenceb__> ok they all link now
2012-06-10T18:12:54 < Laurenceb__> thanks
2012-06-10T18:14:35 < Laurenceb__> so "only" 32% smaller
2012-06-10T18:15:02 <+dekar> how much was it before? :)
2012-06-10T18:15:17 < Laurenceb__> 112544
2012-06-10T18:15:32 < Laurenceb__> now 70080
2012-06-10T18:15:34 <+dekar> I mean the percentage it was smaller before fixing the handlers
2012-06-10T18:15:48 < Laurenceb__> 34%
2012-06-10T18:15:50 <+dekar> might be worth having no handlers :P
2012-06-10T18:19:11 <+dekar> Laurenceb__, we should make some example project for TNT
2012-06-10T18:19:17 <+dekar> making sure it keeps all the handlers etc
2012-06-10T18:19:22 <+dekar> so people can build on that
2012-06-10T18:19:41 < Laurenceb__> *now 77080
2012-06-10T18:20:42 <+dekar> if you feel like making a small example project I'd commit it to the repo
2012-06-10T18:20:54 < Laurenceb__> heh my project is quite big
2012-06-10T18:21:08 < dongs> does it beat armcc yet?
2012-06-10T18:21:24 <+dekar> dongs, well using GOLD it does
2012-06-10T18:21:36 < dongs> ?
2012-06-10T18:21:46 <+dekar> my firmware was 0 bytes when I used the experimental GOLD linker
2012-06-10T18:21:54 < dongs> ya ur super leet
2012-06-10T18:22:51 <+dekar> dongs, well I never really intended to beat armCC, I see there is a reason to use it if you need the smallest size possible (for mass production and cost savings)
2012-06-10T18:23:14 < Laurenceb__> https://github.com/Laurenceb/STM32-Logger
2012-06-10T18:24:42 <+dekar> Laurenceb__, now make it work with GOLD for faster compile times :P
2012-06-10T18:25:21 < Laurenceb__> what is GOLD?
2012-06-10T18:25:59 <+dekar> ld.gold - it's an experimental linker that comes with TNT
2012-06-10T18:26:07 < Laurenceb__> ah
2012-06-10T18:26:12 < dongs> jewgold
2012-06-10T18:26:13 <+dekar> written by google
2012-06-10T18:26:22 < dongs> huh really?
2012-06-10T18:26:25 < Laurenceb__> loldongs
2012-06-10T18:26:33 < dongs> from 2008
2012-06-10T18:26:33 < dongs> lol
2012-06-10T18:26:37 <+dekar> dongs, I think gold is a nazi since it drops all my sections -> nazigold
2012-06-10T18:26:38 < dongs> http://google-opensource.blogspot.jp/2008/04/gold-google-releases-new-and-improved.html
2012-06-10T18:27:09 < dongs> haha its written in C++
2012-06-10T18:27:17 < Laurenceb__> 503
2012-06-10T18:27:26 < Laurenceb__> i think japan finally ran out of power
2012-06-10T18:27:37 <+dekar> dongs, yet better than that weird language they made… go?
2012-06-10T18:27:55 < Laurenceb__> so is gold packaged with TNT?
2012-06-10T18:28:01 <+dekar> yeah
2012-06-10T18:28:10 < Laurenceb__> ok guess id batter use it
2012-06-10T18:28:14 < Laurenceb__> *better
2012-06-10T18:28:27 <+dekar> arm-none-eabi-ld.gold
2012-06-10T18:28:40 < Laurenceb__> as the linker?
2012-06-10T18:28:44 <+dekar> ya
2012-06-10T18:28:50 < Laurenceb__> k
2012-06-10T18:29:05 <+dekar> it has major problems parsing linker scripts though
2012-06-10T18:29:20 <+dekar> so you probably have to do everything using linker flags
2012-06-10T18:31:19 < Laurenceb__> arm-none-eabi-ld.gold: -Wl,--gc-sections,-Map=main.map,-cref: unknown option
2012-06-10T18:32:04 < Laurenceb__> it doesnt seem happy?
2012-06-10T18:33:38 <+dekar> -Wl means that gcc should pass it to the linker
2012-06-10T18:33:46 <+dekar> but you call the linker and not GCC
2012-06-10T18:34:28 <+dekar> you can just do "cp arm-none-eabi-ld.gold arm-none-eabi-ld"
2012-06-10T18:34:35 <+dekar> then you don't have to change your makefile
2012-06-10T18:36:14 < Laurenceb__> wont that overwrite my linker?
2012-06-10T18:39:12 < Laurenceb__> ok it built
2012-06-10T18:39:20 < Laurenceb__> but erm no change
2012-06-10T18:39:30 < Laurenceb__> its supposed to be faster?
2012-06-10T18:39:42 <+dekar> it is supposed to link faster, like times 5
2012-06-10T18:39:52 <+dekar> also it isn't supposed to work actually
2012-06-10T18:39:58 <+dekar> didn't work for me at least
2012-06-10T18:40:00 < Laurenceb__> lol
2012-06-10T18:40:06 <+dekar> it complained about my linkerscript
2012-06-10T18:40:06 < Laurenceb__> hmm
2012-06-10T18:40:18 <+dekar> so somehow you're probably not using gold
2012-06-10T18:40:19 <+dekar> idk
2012-06-10T18:40:39 <+dekar> maybe that "cp arm-none-eabi-ld.gold arm-none-eabi-ld" doesn't actually work
2012-06-10T18:42:56 < Laurenceb__> oh its certainly replaced
2012-06-10T18:43:08 < Laurenceb__> but i cant see a massive change in speed
2012-06-10T18:43:16 < Laurenceb__> its about 3 seconds for each
2012-06-10T18:43:17 <+dekar> Laurenceb__, that's not what I mean, I mean maybe you have to rebuild GCC
2012-06-10T18:43:35 < Laurenceb__> oh
2012-06-10T18:43:48 < Laurenceb__> theres no way im doing that
2012-06-10T18:44:12 < Laurenceb__> takes about 30s to build the whole project, im happy with that
2012-06-10T18:44:28 <+dekar> yeah I don't really care either
2012-06-10T18:44:34 <+dekar> thus I gave up on gold
2012-06-10T18:44:36 <+dekar> XD
2012-06-10T18:44:38 < Laurenceb__> heh
2012-06-10T18:45:02 <+dekar> I think you have to change "--enable-gold" to "--enable-gold=default" or something in the TNT buildscript

2012-06-10T20:18:18 < Rickta59> so to write to flash on the f0 discovery, do i need to use st-flash ( texane/stlink ) or can i just use load in gdb

2012-06-10T20:27:32 < R2COM> for the GPIO ports, there is AFRLH and AFRLL registers, to set alternate functions, you can set AF function to any of 16 pins in AFRH for example, what is the purpose of having two registers?
2012-06-10T20:28:03 < R2COM> oh
2012-06-10T20:28:04 < R2COM> ok
2012-06-10T20:28:06 < R2COM> nevermind
2012-06-10T20:29:25 < BrainDamage> this might be an odd question, but anyone knows a mesh networking lib where I simply provide IO hooks, node discovery ,etc

2012-06-11T03:28:01 < R2COM> with manually toggling registers.. without stdperiph
2012-06-11T03:28:51 < R2COM> now, im wondering would it be relatively not much time consuming making SD-card work, by using the library, and Not using stdperiph... or fatfs highly dependent on stdperiph
2012-06-11T03:28:53 < R2COM> gotta look...
2012-06-11T03:31:04 <+izua> you mean software spi? that's.. brutal.
2012-06-11T03:32:45 < karlp> so, variou speople all provided workign spi code using stdperiph,
2012-06-11T03:32:49 < karlp> and you went and bitbanged it?
2012-06-11T03:33:06 < zyp> he said registers, not pins
2012-06-11T03:33:14 < karlp> oh yeah, ok, good :)
2012-06-11T03:33:24 < zyp> so I guessed he ditched stdperiph but not hardware-spi
2012-06-11T03:38:16 < R2COM> what?
2012-06-11T03:38:17 < R2COM> no
2012-06-11T03:38:28 < R2COM> no i used hardware SPI
2012-06-11T03:38:35 < R2COM> but by talking with SPI registers directly
2012-06-11T03:38:40 < R2COM> CR...SR etc
2012-06-11T03:39:01 < R2COM> ((SPI_TypeDef *) (SPI2_BASE)) -> CR1 |=   etc etc..

2012-06-11T03:40:02 <+izua> hmm
2012-06-11T03:40:03 < R2COM> you already using fatfs?
2012-06-11T03:40:13 <+izua> anyone here messed with libopencm3?
2012-06-11T03:40:31 <+izua> i've been trying to have a project make outside the example dir, but i suck at makefiles ._.
2012-06-11T03:40:55 < zyp> izua, blackmagic does just that, I suggest you have a look at it
2012-06-11T03:41:11 < upgrdman> what does ?= mean in a Makefile?
2012-06-11T03:41:41 < R2COM> zyp: how did you tie fatfs to your own library? you had to change all the calls in fatfs or, you did something else?
2012-06-11T03:42:16 < zyp> I've never used fatfs
2012-06-11T03:42:33 < R2COM> zyp: do you use sd-card at all? or any other data logging card interface to stm32?
2012-06-11T03:42:44 < zyp> no, I've never interfaced with sd-cards
2012-06-11T03:42:48 < R2COM> ok
2012-06-11T03:42:58 <+izua> zyp: the thing from blacksphere tech?

2012-06-11T08:16:32 < zippe> Is it on a branch anywhere?
2012-06-11T08:16:37 < dongs> its in the base code

2012-06-11T08:19:03 < dongs> i kinda kludged it so it looks more or less Ok but if you wanna properly measure it thats cool, i'll take patches :D
2012-06-11T08:20:23 < zippe> Heh, sure
2012-06-11T08:20:39 < zippe> First thing is to get a programming cable together
2012-06-11T08:20:51 < dongs> i made a nice internal SWD connector
2012-06-11T08:21:00 < dongs> soldered it up and hotglued inside
2012-06-11T08:21:06 < dongs> so I can stick in a 4pin 2mm header to program it
2012-06-11T08:21:56 < dongs> original FY shit even kills jtag while running

2012-06-11T08:39:04 < dongs> yes they go nowehre
2012-06-11T08:39:10 < dongs> i had to solder tiny wires to it
2012-06-11T08:39:18 < dongs> the footprint = spi eeprom
2012-06-11T08:39:25 < dongs> thats where I put my 2mm SWD header
2012-06-11T08:39:32 < dongs> and then ran thin transformer wire to debug pins.

2012-06-11T11:01:04 < Tectu> speed issue
2012-06-11T11:01:08 < zyp> I wrote a flashloader, if that's what you're referring to
2012-06-11T11:01:09 < Tectu> dunno, something was there
2012-06-11T11:01:26 < Tectu> not sure what this is
2012-06-11T11:01:34 < zyp> mostly as a challenge, since I don't use the st-link much myself :p
2012-06-11T11:01:59 < zyp> but yeah, it's faster now
2012-06-11T11:01:59 < Tectu> what is the "flashloader" doing?
2012-06-11T11:02:01 < dongs> zippe: which pwm crap.
2012-06-11T11:02:10 < dongs> Tectu: i think shit that loads flash through ram so its fastar
2012-06-11T11:02:10 < Tectu> zyp, so people do get 10kB/s with f4 now?
2012-06-11T11:02:25 < zyp> ha, way more
2012-06-11T11:02:31 < Tectu> aaah, like stm32flash over serial bootloader?
2012-06-11T11:02:53 < zippe> dongs: mm, have you tried building for FY lately?  The includes in board.h seem wrong
2012-06-11T11:03:12 < dongs> yes, it works (inside IDE)
2012-06-11T11:03:14 < zippe> Or is it just trying to build too much?
2012-06-11T11:03:27 < dongs> it'll build some shit that's irrelvant but it should still build
2012-06-11T11:03:29 < zyp> Tectu, when I tested, a full 1M flash took just over 40 seconds
2012-06-11T11:03:32 < Tectu> zyp, can you explain to me what it's doing
2012-06-11T11:03:37 < Tectu> the thing you wrote

2012-06-11T11:04:13 < zippe> Guessing the IDE is not building that part
2012-06-11T11:04:19 < zippe> You using TS or UV?
2012-06-11T11:04:31 < zippe> I can try firing up the heap of crap that is TS if I must
2012-06-11T11:04:36 < Tectu> just wondering.... can you PM people "over github" ?
2012-06-11T11:04:41 < zyp> Tectu, the thing is, when flashing you can only write one word at a time, then you have to wait for a flag before writing the next word
2012-06-11T11:04:56 < zyp> Tectu, so you have a loop repeatedly checking that flag
2012-06-11T11:05:17 < dongs> crapo
2012-06-11T11:05:18 < dongs> urite
2012-06-11T11:05:26 < dongs> i turn off those in the iDE
2012-06-11T11:05:28 < dongs> but not in makefile
2012-06-11T11:05:33 < zyp> Tectu, doing that over usb adds a lot of latency, so you waste a lot of time between writing each word
2012-06-11T11:05:43 < dongs> you dont need to build drv_adc, drv_adxl, dvr_bmp, drv_hmc, drv_mpu, drv_pwm, drv_ledring
2012-06-11T11:05:46 < zippe> The makefile is pretty failtastic; it just compiles "everything"
2012-06-11T11:05:50 < dongs> yeah
2012-06-11T11:05:51 < Tectu> zyp, i understand
2012-06-11T11:05:58 < Tectu> zyp, go on
2012-06-11T11:05:59 < R2COM> dongs: which IDE?
2012-06-11T11:06:02 < dongs> R2COM: keil
2012-06-11T11:06:05 < R2COM> oh
2012-06-11T11:06:09 < R2COM> but isnt it expencive?
2012-06-11T11:06:18 < dongs> but it works
2012-06-11T11:06:19 < zyp> Tectu, a flashloader is a small program that you upload to ram, then you just transfer a block of data to ram, and run the flashloader to copy that block to flash
2012-06-11T11:06:28 < R2COM> oh so you are rich
2012-06-11T11:06:33 < dongs> zippe: you can quickhax it by wrapping those files with #ifndef FY90Q or something.. or fix the makefile..
2012-06-11T11:06:53 < R2COM> its like, 800$ or so if im correct
2012-06-11T11:07:09 < R2COM> mainly because you can simulate peripherals etc...
2012-06-11T11:07:11 < R2COM> i guess...
2012-06-11T11:07:45 < R2COM> i actually played with it a little
2012-06-11T11:07:53 < dongs> R2COM: try $4895
2012-06-11T11:08:02 < R2COM> so you payed 5 grand for it?
2012-06-11T11:08:08 < R2COM> really?
2012-06-11T11:08:38 < dongs> no, i paid for crossworks edu license, when I make > $50k with keil, I'll pay for it too.
2012-06-11T11:08:56 < R2COM> > 50k$ with keil?
2012-06-11T11:08:58 < R2COM> hm
2012-06-11T11:09:13 < R2COM> edu doesnt let to sell
2012-06-11T11:10:05 < R2COM> also, debugger probably more convenient, if it can pop up all main registers, instead of typing addresses in gdb
2012-06-11T11:10:14 < Tectu> zyp, sounds awesome!
2012-06-11T11:10:19 < Tectu> zyp, does it only work for F4?
2012-06-11T11:10:21 < gsmcmullin> zyp: Is your flash loader much faster than mine?
2012-06-11T11:10:24 < R2COM> thats pretty much it i guess...other than that.. not sure what other advantage
2012-06-11T11:10:25 < zippe> dongs: MMA driver too?
2012-06-11T11:10:34 < zyp> gsmcmullin, probably not
2012-06-11T11:10:41 < dongs> zippe: mma?
2012-06-11T11:10:49 < dongs> oh right
2012-06-11T11:10:49 < R2COM> mixed martial arts
2012-06-11T11:10:50 < dongs> dont need that either
2012-06-11T11:11:31 < gsmcmullin> zyp: You said way more than 10k/s above?
2012-06-11T11:11:34 < zyp> gsmcmullin, and there is some other slowness in the texane stuff, ~10 seconds of the 40 seems to be wasted on some internal stuff before starting flashing
2012-06-11T11:11:48 < zyp> I get around 25kB/s
2012-06-11T11:11:52 < R2COM> i get 3KB
2012-06-11T11:12:04 < zyp> blackmagic did 45 kB/s when I tested
2012-06-11T11:12:16 < zippe> hmm, well, that built
2012-06-11T11:12:20 < gsmcmullin> Oh, wow.  I haven't used it with a big project on f4.
2012-06-11T11:12:21 < R2COM> i'v heard from some people that if you use HUB for USB it sometimes boosts speed up, though not sure if its true
2012-06-11T11:12:37 < gsmcmullin> I get about 15k/s into f103.
2012-06-11T11:12:50 < zippe> gsmcmullin: my project's about 600K on the F4 with Lua included
2012-06-11T11:12:50 < R2COM> sometimes i get 4KB/s
2012-06-11T11:13:01 < zippe> But I only flash the bootloader with BM
2012-06-11T11:13:04 < zyp> gsmcmullin, it reports way slower when I do smaller images
2012-06-11T11:13:24 < zippe> The bootloader flashes plenty fast enough
2012-06-11T11:13:27 < Tectu> zyp, does it wonly work for F4 or can i use what you wrote also over dedicated stlinkv2 and F103?
2012-06-11T11:13:49 < R2COM> actually yes, i think so, when i did some very small ones, speed was <1KB
2012-06-11T11:13:50 < zyp> Tectu, there is already another flashloader present for F1 I believe
2012-06-11T11:15:22 -!- R2COM [~blackops@c-98-230-217-221.hsd1.nm.comcast.net] has quit [Quit: Leaving.]
2012-06-11T11:15:45 < zyp> zippe, in any case the final bottleneck is how fast the flash can accept data
2012-06-11T11:16:15 < zyp> gsmcmullin, you are not doing any kind of split-buffering?
2012-06-11T11:16:29 < zyp> i.e. transferring one block to ram while writing another to flash
2012-06-11T11:16:44 < gsmcmullin> zyp: No.  Write one block with the stub to flash it.
2012-06-11T11:17:32 < gsmcmullin> I never thought of it.
2012-06-11T11:18:06 < zyp> I considered trying split-buffering with texane to see how large difference it would make, but I would have to hack around a lot of stuff, so I didn't bother
2012-06-11T11:18:33 < gsmcmullin> zyp: I'd like to profile it first.
2012-06-11T11:18:56 < zyp> yeah
2012-06-11T11:19:34 < zyp> if the time spent transferring to ram is way shorter than the time spent executing the flashloader, there wouldn't be much gains
2012-06-11T11:21:09 < gsmcmullin> I'd hate to invest the effort and make the program more complicated for possibly no gain.
2012-06-11T11:21:30 < zyp> either way, when you're at the point when you have the flashloader writing continously, you've pretty much reached the max possible flashing speed for that chip
2012-06-11T11:22:12 < gsmcmullin> Yeah, but I don't know how much time is wasted transferring to ram or waiting for the USB.
2012-06-11T11:24:32 < zyp> and I don't really mind wasting an afternoon on something, as long as I learn something from it ;)
2012-06-11T11:26:33 < gsmcmullin> Same applies to me.  I'd learn more and it'd be more useful to get profiling information out of the trace port.
2012-06-11T11:26:57 < zyp> ah, yeah
2012-06-11T11:26:58 < gsmcmullin> ...but so little time...
2012-06-11T11:27:29 < zyp> I've been meaning to look at your magictpa stuff, but I haven't gotten around to it yet
2012-06-11T11:28:24 < gsmcmullin> Let me know if you try it.  It's really more of a proof-of-concept than anything else at this stage.
2012-06-11T11:28:39 < zyp> I'm kind of putting that off until I replace my workstation after my vacation, which means I get a newer OS X version with USB IAD support :p
2012-06-11T11:28:50 < gsmcmullin> Cool.
2012-06-11T11:29:02 < zyp> upgrading OS X on the old one seems like a waste of time when I'm replacing it anyway
2012-06-11T11:29:56 < gsmcmullin> You may still have issues with magictpa.  Mac doesn't like libusb using the same device as the cdcacm driver, even though they're on different interfaces.
2012-06-11T11:31:15 < gsmcmullin> It may work.  The problem I had before was using the control endpoint, this is another bulk endpoint, so it's not the same.
2012-06-11T11:34:59 < zyp> we'll see
2012-06-11T11:35:22 < zyp> it can probably be solved in one way or another anyway
2012-06-11T11:36:48 < zyp> might be possible to do an alternative configuration for non-cdc gdb data, and integrate a gdb-proxy with the tpa stuff, and force it into that configuration?

2012-06-11T17:02:40 < dongs> shit better get on this
2012-06-11T17:16:13 < jon1012> spi prescaler give the freq of the spi bus right ?
2012-06-11T17:16:17 < jon1012> or two times it ?
2012-06-11T17:17:31 < dongs> spi prescaler is ABP/AHB clk / prescaler
2012-06-11T17:17:38 < dongs> whatever bus SPI is on
2012-06-11T17:17:45 < jon1012> oh I see
2012-06-11T17:17:51 < dongs> i.e. higher prescaler = slower
2012-06-11T17:19:09 < jon1012> thanks :)
2012-06-11T17:19:21 < jon1012> I thought it was a prescaler over system clock
2012-06-11T17:19:32 < jon1012> now I see that for spi1 it's apb2 for example
2012-06-11T17:19:40 < dongs> no, because it cant go faster than the bus its connected to
2012-06-11T17:19:42 < dongs> right
2012-06-11T17:20:28 < jon1012> hehe, I was wondering why it was working perfectly with  prescaler of 8 on enc28j60 while the chip was intended to run at max 20 mhz
2012-06-11T17:20:39 < dongs> well yeah
2012-06-11T17:20:45 < dongs> 'i think apb is like 36mhz?
2012-06-11T17:20:47 < dongs> so /8...
2012-06-11T17:20:49 < dongs> you got way under 20mhz.
2012-06-11T17:20:53 < jon1012> yeah
2012-06-11T17:21:05 < jon1012> well, apb2 prescaler is at 2
2012-06-11T17:21:20 < jon1012> and system clock at 240 (yeah a bit overclocked)
2012-06-11T17:21:31 < dongs> lolwat
2012-06-11T17:21:39 < dongs> what chip is this
2012-06-11T17:21:45 < jon1012> stm32f407vgt6
2012-06-11T17:22:02 < dongs> funtimes
2012-06-11T17:22:54 < jon1012> (the only thing to take care of was to get a good pll_q value, to have a working flash
2012-06-11T17:23:00 < dongs> what doesn't work at those speeds?
2012-06-11T17:23:18 < jon1012> from what I see, nothing as long as the prescalers for peripherals are good
2012-06-11T17:23:36 < jon1012> and the chip doesn't even get hot at all
2012-06-11T17:25:03 < dongs> heh i doubt it will

2012-06-11T17:29:42 <+izua> a lot
2012-06-11T17:29:47 <+izua> no internet since ~13:00

2012-06-11T17:31:30 <+izua> if she powers off the router, she won't get internet either :P
2012-06-11T17:31:51 < pelrun> oh weird
2012-06-11T17:32:14 < pelrun> just realised there's an 'interrupt' gcc attribute for arm
2012-06-11T17:32:18 < pelrun> and I haven't been using it
2012-06-11T17:32:42 < pelrun> wonder what the difference is on cortexM3
2012-06-11T17:32:55 < karlp> izua: did you get your makefile to build with libopencm3?
2012-06-11T17:33:32 <+izua> i did something much simpler
2012-06-11T17:34:16 < karlp> I built a project myself to do libopencm3 standalone, https://github.com/karlp/opencm3-standalone/blob/master/Makefile.include
2012-06-11T17:34:20 <+izua> changed the libopencm3 makefile to output compiler commands, recompiled a custom project in the example dir, made a file with the commands shown with a bash shebang, ghetto makefile
2012-06-11T17:34:35 < karlp> there was just one or two paths that were wrong
2012-06-11T17:34:41 < karlp> but yeah, I based it off the example projects
2012-06-11T17:34:46 <+izua> will probably hack it in a makefile that uses a file structure I like though, with src/ bin/ obj/, etc
2012-06-11T17:35:03 <+izua> also, the blacksphere looks pretty cool
2012-06-11T17:35:26 < pelrun> ah, isr attribute is a no-op for cortex-M3 gcc
2012-06-11T17:38:09 < karlp> don't need attributes for isrs on m3 :)
2012-06-11T17:40:11 < pelrun> yeah, my code was working, just wanted to verify it was not needed

2012-06-11T17:53:02 < dongs> The best way to confirm you will get the full document in your image is to hold you phone 310mm above the document and you'll be able to see what it will capture.

2012-06-11T21:05:29 <+izua> strain*
2012-06-11T21:05:35 <+dekar> izua, then better never try reading newspapers
2012-06-11T21:05:43 <+dekar> those have like 600dpi
2012-06-11T21:05:52 <+dekar> macbook only has 240dpi I think
2012-06-11T21:06:59 <+izua> printwork needs many times the amount of dpi as display stuff to get similar letter (erm? glyph?) quality
2012-06-11T21:07:23 <+izua> but yeah, newspapers print with a small font anyway
2012-06-11T21:08:17 <+dekar> I mean we do shit like anti-aliasing to compensate for the low DPI on todays displays
2012-06-11T21:08:32 <+dekar> print doesn't do that

2012-06-11T21:41:23 <+Steffanx> for
2012-06-11T21:43:18 <+dekar> Steffanx, mediawiki
2012-06-11T21:43:40 <+dekar> Steffanx, though izua was the one who took the wiki down in the first place
2012-06-11T21:44:02 <+izua> there was no wiki, it was my temporary website.
2012-06-11T21:44:20 <+dekar> izua, it actually was a mediawiki
2012-06-11T21:44:30 <+izua> it happend to be based on mediawiki, yes
2012-06-11T21:44:39 <+Steffanx> Ha
2012-06-11T21:44:47 <+izua> it's the best cms around, what
2012-06-11T21:45:11 <+izua> nobody could edit it but me, and it had almost no special pages visible. hardly a wiki :P
2012-06-11T21:45:53 <+dekar> izua, yet you were talking about using it for #stm32
2012-06-11T21:46:20 <+dekar> back then when there were no people in #stm32
2012-06-11T21:46:31 <+izua> i said, i could set up a subdomain on izua.ro, for a different cms :P
2012-06-11T21:46:42 <+izua> yes, you make a very compelling argument :P
2012-06-11T21:46:57 <+Steffanx> I was in #stm32 !
2012-06-11T21:47:06 <+izua> also, i was about to say that
2012-06-11T21:47:34 <+izua> Steffanx: i also recall when he said he's give us a million € each
2012-06-11T21:48:15 <+dekar> izua, you wish
2012-06-11T21:49:28 <+Steffanx> From the company cc izua ?
2012-06-11T21:49:47 <+izua> don't care
2012-06-11T21:49:53 <+Steffanx> pi:P
2012-06-11T21:50:10 <+dekar> izua, you don't care about the million? :)
2012-06-11T21:50:21 <+izua> i don't care where the money comes from
2012-06-11T21:50:56 <+dekar> you better care, since I don't have a million to begin with :P
2012-06-11T21:51:09 <+Steffanx> So company cc it is
2012-06-11T21:55:07 <+dekar> Steffanx, you're mixing it up, it was your mom who sent it
2012-06-11T21:55:35 <+dekar> since izua doesn't care where the money comes from...

2012-06-11T22:08:57 <+izua> haven't seen him around in other channels or freenode since
2012-06-11T22:09:03 <+izua> well, not under that nickname
2012-06-11T22:09:10 <+dekar> Steffanx, I'm not judging you, though incest is illegal in Germany. That's how nazi we are, eugenics and stuff!
2012-06-11T22:09:22 <+izua> but incest keeps the bloodline pure
2012-06-11T22:09:27 <+Steffanx> At least i'm not from Germany D:
2012-06-11T22:09:28 <+izua> that's anti-eugenics at its best
2012-06-11T22:09:51 <+Steffanx> but you are .. so what are you trying to say dekar ?
2012-06-11T22:10:25 <+izua> he's bored
2012-06-11T22:11:20 <+Steffanx> The performance of the gpu of the rpi is indeed pretty impressive
2012-06-11T22:11:27 <+Steffanx> 1080p without any trouble
2012-06-11T22:11:42 <+izua> did you order one?
2012-06-11T22:11:47 <+Steffanx> Yep
2012-06-11T22:11:52 <+izua> where? o_o
2012-06-11T22:11:58 <+Steffanx> RS
2012-06-11T22:12:12 <+dekar> Steffanx, are you talking about the hardware decoding?
2012-06-11T22:12:17 <+Steffanx> Yes
2012-06-11T22:12:22 <+dekar> but it's limited to a few codecs, isn't it?
2012-06-11T22:12:27 <+Steffanx> Yes
2012-06-11T22:12:50 <+izua> .wav and uncompressed bmp streams?
2012-06-11T22:12:50 <+Steffanx> but the only codec i use is supported :)
2012-06-11T22:12:57 <+dekar> so if you for example have h264 hi10p it will fail :/
2012-06-11T22:13:14 <+Steffanx> Isn't h264 the only supported codec?
2012-06-11T22:13:23 <+Steffanx> or one of the few
2012-06-11T22:13:46 <+dekar> but only the basic profiles I guess, my nvidia card fails to decode the high 10 profile as well
2012-06-11T22:13:56 <+dekar> generates horrible artefacts
2012-06-11T22:14:00 <+Steffanx> I don't use that anyway
2012-06-11T22:14:15 <+dekar> it's coming up though, has better compression ratios
2012-06-11T22:14:39 <+Steffanx> It's decoding the AC3 audio in sw.. but that isn't a real problem
2012-06-11T22:15:31 <+dekar> "Significantly higher compression ratios resulting in vastly decreased file sizes. The first rounds of testing show a 20-40% improvement on file sizes"
2012-06-11T22:15:38 <+dekar> http://haruhichan.com/wpblog/index.php/205/hi10p-info-guide.html
2012-06-11T22:15:49 <+dekar> Steffanx, doesn't it output AC3 via hdmi?
2012-06-11T22:16:14 < Laurenceb__> raspberry pron
2012-06-11T22:16:30 <+Steffanx> It does dekar
2012-06-11T22:16:36 <+Steffanx> but it's decoded in sw afaik
2012-06-11T22:17:09 <+dekar> Steffanx, umm what if you have a AV-receiver? those usually decode AC3 for you
2012-06-11T22:17:24 <+dekar> my atom does just pass-through
2012-06-11T22:18:01 <+Steffanx> I can do that, but my tv cant
2012-06-11T22:18:14 <+dekar> ah I see

2012-06-11T22:19:25 <+dekar> Laurenceb__, I want 13"
2012-06-11T22:19:36 <+Steffanx> I want 25"
2012-06-11T22:19:44 <+Steffanx> And 3 times that resolution
2012-06-11T22:19:55 < Laurenceb__> lol

2012-06-11T22:20:37 <+Steffanx> Uh?
2012-06-11T22:21:02 <+Steffanx> Time for a reboot, my touch pad is doing weird things
2012-06-11T22:21:08 <+dekar> well I think I'll get 13" in maybe a year, but you'll probably have to wait longer for your 25" laptop
2012-06-11T22:21:23 <+Steffanx> bb uptime of 48 days
2012-06-11T22:21:45 <+dekar> like if that was a lot :/
2012-06-11T22:21:49 <+Steffanx> No
2012-06-11T22:21:53 <+Steffanx> but the touchpad gone mad
2012-06-11T22:22:16 <+Steffanx> And all tries to fix it failed
2012-06-11T22:22:23 <+Steffanx> so the only solution is a .. reboot
2012-06-11T22:22:30 <+dekar> that sucks
2012-06-11T22:22:58 <+dekar> did you try unloading and reloading the kernel module?
2012-06-11T22:23:34 <+Steffanx> Oh, a sleep seems to be enough

2012-06-11T22:27:22 <+Steffanx> Wha, Apple gone mad .. a macbook pro with a hdmi port
2012-06-11T22:35:39 <+dekar> I think it's great
2012-06-11T22:36:14 <+dekar> DVI connectors are too big for the macbook
2012-06-11T22:36:19 <+dekar> and hdmi is convenient
2012-06-11T22:36:29 <+dekar> those adaptors are annoying
2012-06-11T22:37:26 <+Steffanx> Yeah, but Apple is into displayport/thunderbolt/whatever they call it

2012-06-11T22:49:54 <+dekar> Steffanx, agree

2012-06-11T22:50:23 <+Steffanx> dollar to euro +100 =  2.279,00 euro  :S
2012-06-11T22:51:02 <+dekar> Laurenceb__, what do you mean?
2012-06-11T22:51:24 <+dekar> they build proprietary drivers linked for some specific linux version -> meaning you can't update
2012-06-11T22:51:55 <+dekar> besides that android uses no Xorg, thus you can't use an Ubuntu desktop for example
2012-06-11T22:52:15 < Laurenceb__> sure
2012-06-11T22:52:18 <+dekar> there are barely any SoCs with proper upstream support, the only one I know of is OMAP3
2012-06-11T22:52:25 <+Steffanx> Who wants to run ubuntu?!!??!?!
2012-06-11T22:52:26 < Laurenceb__> i mean non android
2012-06-11T22:52:38 < Laurenceb__> ok maybe i was wrong

2012-06-11T22:56:57 <+Steffanx> Not worth it
2012-06-11T22:59:02 <+dekar> getting linux running on random SoCs is too much work anyway
2012-06-11T22:59:35 <+Steffanx> Getting linux running on anything is too much work :P
2012-06-11T22:59:35 <+dekar> I once compiled mainline linux for arm and tried to boot it on some Tegra2 -> instant brick
2012-06-11T22:59:45 <+dekar> didn't even output anything to serial anymore
2012-06-11T22:59:58 <+dekar> Steffanx, fedora boots fine on my macbook, no work needed
2012-06-11T23:00:10 <+Steffanx> Until you have to compile stuff yourself
2012-06-11T23:00:23 <+dekar> that is easier than on OSX
2012-06-11T23:00:38 <+Steffanx> I mean the kernel en stuff
2012-06-11T23:01:00 <+dekar> I doubt compiling darwin is any easier
2012-06-11T23:01:01 <+Steffanx> No prebuilt distro
2012-06-11T23:01:21 <+dekar> Steffanx, I have built Linux for x86er many times, that's not hard
2012-06-11T23:01:24 <+Steffanx> Anyway battery is almost empty
2012-06-11T23:01:26 <+dekar> for ARM it is

2012-06-11T23:01:58 <+Steffanx> bug me with what?
2012-06-11T23:02:02 <+izua> setting up wiki
2012-06-11T23:02:17 <+Steffanx> I won't go to sleep
2012-06-11T23:02:22 <+izua> i'll just set your password to steffanx correct horse battery staple
2012-06-11T23:02:25 <+dekar> Steffanx, you've never built linux, did you? you usually use "make menuconfig"
2012-06-11T23:02:27 <+izua> you just plug yourself in ac?
2012-06-11T23:02:40 <+Steffanx> No
2012-06-11T23:02:44 <+Steffanx> my pc will go to sleep i wont
2012-06-11T23:02:50 <+izua> that's as low as i got dekar
2012-06-11T23:02:51 <+Steffanx> Isn't the what everyone does dekar ?
2012-06-11T23:03:07 <+Steffanx> I compiled linux for my AVR32
2012-06-11T23:03:18 <+Steffanx> with menuconfig :P
2012-06-11T23:03:36 <+Steffanx> And once for my router.. without menuconfig
2012-06-11T23:03:39 <+Steffanx> and it terrible failed
2012-06-11T23:04:08 <+dekar> in any case, mainline support usually is only good for x86er
2012-06-11T23:05:15 <+dekar> and I'd stay away from random ARM SoCs, I've tried several
2012-06-11T23:05:44 < BrainDamage> like ... stm32? :p
2012-06-11T23:06:32 <+dekar> BrainDamage, yeah like if the stm32 runs linux (don't come with µCLinux, that's uber limited)
2012-06-11T23:06:47 <+izua> i doubt it will, without a mmu
2012-06-11T23:06:55 < BrainDamage> I meant your sentence

2012-06-11T23:07:15 < BrainDamage> I meant your sentence out of context*
2012-06-11T23:08:43 <+dekar> BrainDamage, well I use the stm32 for a product we sell. I just don't think it's worth wasting months writing drivers and the like for a hobby project

2012-06-11T23:09:17 <+dekar> that Leviathan guy hacked graphics drivers to get Xorg working on some qualcomm and he also wrote alas drivers
2012-06-11T23:09:19 < BrainDamage> it was a joke, not a serious answer
2012-06-11T23:09:20 <+dekar> waste of time imo
2012-06-11T23:10:51 <+dekar> *alsa
2012-06-11T23:11:46 <+dekar> that phone he worked on now has some barely working GNU/Linux, some drivers crash when you enable swap
2012-06-11T23:11:59 <+dekar> and said phone has been out of production for quite a while now
2012-06-11T23:12:11 <+dekar> it will probably never get proper mainline support
2012-06-11T23:12:22 <+dekar> and that SoC is one of the better supported ones
2012-06-11T23:12:39 <+dekar> I think mainline linux boots on it (without video, audio etc)

2012-06-11T23:18:32 < BrainDamage> well, I'd argue that a microcontroller fits the description of a SoC better than most SoC, but let's not digress too much :p

2012-06-11T23:40:51 < Laurenceb__> uClinux has been run on stm32
2012-06-11T23:41:03 < Laurenceb__> i have an ngw100 running linux on avr32
2012-06-11T23:41:54 <+dekar> Laurenceb__, <dekar> BrainDamage, yeah like if the stm32 runs linux (don't come with µCLinux, that's uber limited)
2012-06-11T23:42:23 <+dekar> besides that the stm32 port isn't upstream, vanilla linux can't boot on the stm32. This basically was my point
2012-06-11T23:43:14 <+dekar> BrainDamage, agree to disagree
2012-06-11T23:43:44 < Laurenceb__> linux is overrated
2012-06-11T23:44:15 <+dekar> what makes you think so?
2012-06-11T23:45:03 < Laurenceb__> well its just boring in embedded
2012-06-11T23:45:19 < Laurenceb__> whats so amazing about embedded linux?
2012-06-11T23:45:52 <+dekar> Laurenceb__, to me linux is mostly useful for the bazillion drivers as well as an API abstracting the hardware
2012-06-11T23:45:58 < Laurenceb__> yeah
2012-06-11T23:46:19 < Laurenceb__> which tends to become bloated and not very relevant in embedded
2012-06-11T23:46:42 <+dekar> depends on which embedded we're talking about
2012-06-11T23:46:48 < Laurenceb__> true
2012-06-11T23:46:49 <+dekar> for deeply embedded targets I agree
2012-06-11T23:46:57 <+dekar> for Android phones I would disagree
2012-06-11T23:47:14 <+dekar> I think linux makes sense on smartphones as a hardware abstraction layer
2012-06-11T23:47:29 <+dekar> for the vendors it is much easier to port linux, than some proprietary OS
2012-06-11T23:47:30 < Laurenceb__> yeah
2012-06-11T23:47:51 <+dekar> they have to code less and can bring their stuff faster to the market
2012-06-11T23:48:12 <+dekar> besides that there is a ton of linux experts out there, so that is easier for them as well
2012-06-11T23:48:37 <+dekar> I mean just look at BadaOS with their nucleus kernel
2012-06-11T23:48:59 <+dekar> Samsung actually gave me one of their Bada phones for free at some developer gathering I was invited to
2012-06-11T23:49:07 <+dekar> yet it fails horribly :)
2012-06-11T23:49:15 <+dekar> I sold it on ebay and got an android
2012-06-11T23:49:44 < Laurenceb__> yeah im talking about more deeply embedded stuff
2012-06-11T23:49:51 < Laurenceb__> with there were some meago phones
2012-06-11T23:50:06 <+dekar> tizen you mean? :P
2012-06-11T23:51:34 <+dekar> Laurenceb__, and yeah linux doesn't make sense on systems like the STM32 - you have to load it on external SRAM which has one wait state slowing execution down...
2012-06-11T23:51:46 <+dekar> it's obviously far too bloated for our micro
2012-06-11T23:53:20 < Laurenceb__> yet loads of people get obsessive about running it on hardware of this level
2012-06-11T23:54:44 <+dekar> Laurenceb__, µCLinux lacks most of its POSIX conformity, you don't even have basic threading features like fork()
2012-06-11T23:54:54 <+dekar> not worth it imo

2012-06-12T01:02:30 < R2COM> so, on which smartphones one can run true linux?
2012-06-12T01:02:42 < R2COM> samsung galaxy II? iphone II? or what?
2012-06-12T01:02:48 < zyp> is android not true linux?
2012-06-12T01:03:00 < R2COM> im not sure, im not into that stuff was just curious
2012-06-12T01:03:35 < zyp> then let me inform you that android is true linux, with a different userland
2012-06-12T01:03:42 <+dekar> R2COM, well I guess "true linux" is more like GNU/Linux
2012-06-12T01:04:08 <+dekar> zyp, well they changed a lot actually
2012-06-12T01:04:28 < zyp> it's not that different
2012-06-12T01:04:32 <+dekar> they don't use alsa for audio output
2012-06-12T01:04:45 <+dekar> they use some different graphics framwork
2012-06-12T01:04:51 <+dekar> *framework
2012-06-12T01:05:20 < zyp> isn't graphics mostly userland?
2012-06-12T01:05:37 < Laurenceb__> in b4 RMS
2012-06-12T01:05:45 <+dekar> zyp, nope - traditionally on *NIX system the Xserver has kernel privileges
2012-06-12T01:06:01 <+dekar> and the Xserver contains the graphics drivers
2012-06-12T01:06:23 < zyp> anyway, consider this
2012-06-12T01:06:42 < zyp> pandaboard can run normal linux distributions
2012-06-12T01:06:51 < R2COM> so, does it mean i can run nearly any Linux application i run on my RHEL6, on the Android, on one of those phones?
2012-06-12T01:07:07 <+dekar> zyp, panda board is build around one of the best supported SoCs out there
2012-06-12T01:07:10 < zyp> a lot of today's smartphones are practically identical hardware-wise
2012-06-12T01:07:23 < zyp> i.e. OMAP4-based
2012-06-12T01:07:25 <+dekar> OMAP3 has full mainline support and OMAP4 has partial support
2012-06-12T01:07:36 < BrainDamage> R2COM: I suspect Xorg won't run on them
2012-06-12T01:07:57 <+dekar> R2COM, no Xorg, no Sound
2012-06-12T01:08:00 < zyp> R2COM, you can't run x86 code on an arm processor
2012-06-12T01:08:14 < BrainDamage> plus I don't know what patches most android flavours have on top of the kernel
2012-06-12T01:08:19 <+dekar> R2COM, you can run your commandline redhat stuff on android
2012-06-12T01:08:22 < BrainDamage> but most command line apps should work
2012-06-12T01:08:40 < R2COM> hm
2012-06-12T01:08:40 < zyp> sure, it's still all posix
2012-06-12T01:09:09 <+dekar> but the worst about android are the proprietary drivers, you're usually bound to one hacked together kernel with proprietary modules you'll never see the sources of
2012-06-12T01:09:09 < BrainDamage> if someone does an xorg for android, then most of the stuff should work
2012-06-12T01:09:18 <+dekar> so you can't update the kernel
2012-06-12T01:09:19 < R2COM> what about writing your app for it? would it be easy portable thing PC(Linux)--->Android, if written in C?
2012-06-12T01:09:20 < R2COM> or
2012-06-12T01:09:23 < R2COM> no?
2012-06-12T01:09:32 < R2COM> also
2012-06-12T01:09:32 <+dekar> and you can't use android drivers for Xorg and ALSA
2012-06-12T01:09:32 < BrainDamage> depends on the libs / what it does
2012-06-12T01:09:41 < zyp> let me add that I work on android stuff for a living, I don't notice much difference from other embedded linux stuff
2012-06-12T01:09:50 < R2COM> one more thing interesting, is there any way connect some USB device to one of those Android phones?
2012-06-12T01:10:01 < BrainDamage> some have usb host capability
2012-06-12T01:10:06 <+dekar> R2COM, libusb
2012-06-12T01:10:10 < BrainDamage> but it's a minority
2012-06-12T01:10:12 < R2COM> ok
2012-06-12T01:10:18 <+dekar> R2COM, you only need root
2012-06-12T01:10:18 < R2COM> but do those phones have Micro USB output?
2012-06-12T01:10:22 < R2COM> or something?
2012-06-12T01:10:24 < zyp> the chipsets got OTG support, but most phones are not wired to provide 5V to connected devices
2012-06-12T01:10:27 < BrainDamage> not all
2012-06-12T01:10:36 < BrainDamage> a minority has usb host support
2012-06-12T01:11:06 <+dekar> just buy a tablet with usb port if you want that
2012-06-12T01:11:08 < zyp> all the devboards we got at work got full host support
2012-06-12T01:11:28 < zyp> so it's just a matter of phone manufacturers to hook it up
2012-06-12T01:11:36 < R2COM> for example, it could be useful, say i have some board, or hardware, and somewhere on a field i want to tweak its parameters, and i dont want to drag my laptop every time, so i run my app on android phone, and do the job (given that the application is written for it and drivers too)
2012-06-12T01:12:06 < zyp> sure
2012-06-12T01:12:29 < R2COM> which phone would you recommend from the latest ones? capable of such stuff?
2012-06-12T01:12:36 < R2COM> and supporting android
2012-06-12T01:12:51 < R2COM> i heard there are some already with quad cores
2012-06-12T01:12:52 < zyp> I don't know, I don't have much experience with actual recent phones, just devboards
2012-06-12T01:12:56 < R2COM> and 8MP camera as well?
2012-06-12T01:13:28 <+dekar> R2COM, just get a IOIO or something like that, all android devices interface to IOIO
2012-06-12T01:13:44 < BrainDamage> that's because the ioio is a usb host
2012-06-12T01:13:49 < zyp> yep
2012-06-12T01:13:51 <+dekar> I know
2012-06-12T01:13:57 < zyp> that's because a lot of devices are only device
2012-06-12T01:14:00 < BrainDamage> he wants to hook to random boards
2012-06-12T01:14:07 < zyp> does he?
2012-06-12T01:14:21 < BrainDamage> "i have some board, or hardware, and somewhere on a field i want to tweak its parameters, "
2012-06-12T01:14:26 <+dekar> oh, like using OpenOCD on his android phone to jtag some board?
2012-06-12T01:14:46 < BrainDamage> that's what I took from it
2012-06-12T01:14:59 < BrainDamage> I guess tought you could reimplement that using the ioio
2012-06-12T01:15:03 < BrainDamage> like ioio to jtag
2012-06-12T01:15:15 < BrainDamage> but it'd be a specific app, toggling the gpio
2012-06-12T01:15:18 <+dekar> read that blog and pick some device he suggests: http://blog.the-leviathan.ch/
2012-06-12T01:15:25 < zyp> BrainDamage, doesn't have to
2012-06-12T01:15:33 < R2COM> im looking at IOIO
2012-06-12T01:15:39 < zyp> can run a full gdbserver on the ioio and just pipe it to gdb on the phone
2012-06-12T01:15:42 <+dekar> that guy installs GNU/Linux systems like Gentoo and android devices
2012-06-12T01:15:54 < R2COM> it has USB
2012-06-12T01:16:04 < R2COM> so... what would i need that?
2012-06-12T01:16:07 < R2COM> why*
2012-06-12T01:16:26 < R2COM> i guess its for those who want to toggle LEDs from android or something
2012-06-12T01:16:28 <+dekar> R2COM, it allows your android device to interface GPIO pins
2012-06-12T01:16:39 < R2COM> yea.. i was talking about different stuff
2012-06-12T01:16:41 <+dekar> R2COM, well I didn't fully understand what you want
2012-06-12T01:16:44 < R2COM> if there is already board with USB
2012-06-12T01:16:56 < R2COM> and that board, lets say needs to be tweaked
2012-06-12T01:17:00 < R2COM> from its USB port
2012-06-12T01:17:10 < BrainDamage> you want a phone with usb hosting capability
2012-06-12T01:17:30 < R2COM> host... or actually device would work too
2012-06-12T01:17:45 < BrainDamage> the other board must support usb hosting then
2012-06-12T01:17:48 < R2COM> its just, i suppose, in that case, one would have to write a device drivers for Android right?
2012-06-12T01:17:52 < R2COM> to interface with my board
2012-06-12T01:17:56 <+dekar> R2COM, that device maybe? http://blog.the-leviathan.ch/?p=433
2012-06-12T01:17:56 < R2COM> yes
2012-06-12T01:17:58 < BrainDamage> one of the endpoints needs to have hosting capability
2012-06-12T01:18:05 < R2COM> the other board lets say supports hosting usb
2012-06-12T01:18:16 < BrainDamage> then any androind phone should work
2012-06-12T01:18:22 <+dekar> that transformer tablet only runs botched up kernels made by nvidia, but you probably won't care about that
2012-06-12T01:18:24 < BrainDamage> but to access usb you need root

2012-06-12T01:18:32 < R2COM> yeah what about being root?
2012-06-12T01:18:49 < R2COM> is it blocked to be root in android or what?
2012-06-12T01:19:13 <+dekar> R2COM, on most devices it is
2012-06-12T01:19:18 < BrainDamage> most vendors don't give you root access
2012-06-12T01:19:27 <+dekar> R2COM, anyway if your external board has USB host then you don't need root
2012-06-12T01:19:47 <+dekar> you just have to implement the android debug bridge protocol
2012-06-12T01:19:55 < R2COM> oh ok
2012-06-12T01:19:57 <+dekar> or the android accessory protocol
2012-06-12T01:20:02 < R2COM> but thats stupid that vendors dont give root
2012-06-12T01:20:08 < R2COM> ok
2012-06-12T01:20:15 < R2COM> so board needs to be a USB host then
2012-06-12T01:20:18 <+dekar> R2COM, vendors don't want you to brick your device
2012-06-12T01:20:26 <+dekar> R2COM, think of "rm -rf /"

2012-06-12T01:20:53 <+dekar> R2COM, many do
2012-06-12T01:21:08 <+dekar> you have to unlock those devices at some vendor website though

2012-06-12T01:31:48 <+dekar> well I hate the idea of having to run botched up "android-kernels"
2012-06-12T01:32:01 <+dekar> but for you probably any device will do
2012-06-12T01:32:08 < R2COM> hm
2012-06-12T01:32:10 <+dekar> I would suggest going for a NEXUS device
2012-06-12T01:32:15 -!- Kevin`_ is now known as Kevin`
2012-06-12T01:32:16 < R2COM> looking..
2012-06-12T01:32:17 <+dekar> since they come unlocked
2012-06-12T01:32:32 <+dekar> nexus one, nexus s or nexus galaxy
2012-06-12T01:32:39 <+dekar> only dual core though
2012-06-12T01:32:39 < R2COM> what about HTC?
2012-06-12T01:32:52 <+dekar> what about HTC?
2012-06-12T01:32:56 <+dekar> nexus one is HTC
2012-06-12T01:33:08 <+dekar> nexus s and nexus galaxy are samsung
2012-06-12T01:33:27 <+dekar> but the nexus brands marks devices supported directly by google targeted at developers
2012-06-12T01:33:28 < R2COM> quad core?
2012-06-12T01:33:44 <+dekar> what? there is no nexus quadcore
2012-06-12T01:34:27 <+dekar> well get what you like. buy a phone, use it for a year and throw it away once the vendor stops shipping any updates
2012-06-12T01:34:39 <+dekar> that's how things go for android
2012-06-12T01:34:50 < R2COM> heh
2012-06-12T01:35:05 < R2COM> so 300$ or so just for year
2012-06-12T01:35:11 <+dekar> you have some hacked together kernel by the vendor, they give you updates for maybe a year and then you're basically on your own
2012-06-12T01:35:19 -!- TitanMKD [Titan@chl26-1-88-183-104-56.fbx.proxad.net] has quit []
2012-06-12T01:35:38 <+dekar> and you can't install the latest linux kernels on your device
2012-06-12T01:35:46 <+dekar> just the kernel hacked together by the vendor
2012-06-12T01:36:27 <+dekar> so if you want to install the latest android on your device everything fails. you might still get an image, but no hardware acceleration, camera stops working and so on
2012-06-12T01:36:43 < R2COM> hm
2012-06-12T01:36:47 <+dekar> thus you only have the option to sell it on ebay and buy a new device
2012-06-12T01:37:02 <+dekar> that's why I don't think android is normal linux
2012-06-12T01:37:06 < R2COM> sell for like 20$ or so then
2012-06-12T01:37:16 <+dekar> it might be some hacked linux, but it's not what I want when I think about linux
2012-06-12T01:37:29 < R2COM> i see now, HTC ONE X, quad core
2012-06-12T01:37:33 <+dekar> that's why my old phone runs debian now
2012-06-12T01:37:41 <+dekar> R2COM, yeah well get it
2012-06-12T01:38:26 <+dekar> I only had HTC so far, though I am not too pleased with the devices
2012-06-12T01:38:36 <+dekar> I'd rather go for samsung
2012-06-12T01:38:41 < R2COM> its not available yet
2012-06-12T01:38:46 <+dekar> and well I'd go for the developer nexus phone
2012-06-12T01:38:49 <+dekar> nexus galaxy
2012-06-12T01:38:52 <+dekar> since it is open
2012-06-12T01:38:58 <+dekar> and since the SoC is an OMAP4
2012-06-12T01:39:07 <+dekar> which is one of the best supported SoCs out there
2012-06-12T01:39:23 <+dekar> for upstream GNU/Linux at least
2012-06-12T01:40:29 < R2COM> so what you say is, once its not being updated by manufacturer, its an option to install Debian and stuff?
2012-06-12T01:40:38 < R2COM> is it pain in the ass or smooth process?
2012-06-12T01:40:46 <+dekar> is what pain in the ass?
2012-06-12T01:40:58 <+dekar> running debian on your phone? a lot of pain!
2012-06-12T01:41:02 < R2COM> put debian on say... HTC ONE X, after one year, when its not supported
2012-06-12T01:41:06 < R2COM> oh
2012-06-12T01:41:18 <+dekar> R2COM, you probably won't have ANY drivers
2012-06-12T01:41:19 < R2COM> you got all its peripheral working?
2012-06-12T01:41:20 < R2COM> camera etc?
2012-06-12T01:41:34 <+dekar> no display output, no sound, no camera, no bluetooth, no wifi, no radio
2012-06-12T01:41:38 < R2COM> yeah... thats a lot of dedication, im not sure if ill have time for that shit
2012-06-12T01:41:43 <+dekar> maybe just serial console
2012-06-12T01:42:01 <+dekar> R2COM, you can still sell it on ebay like normal people
2012-06-12T01:42:04 <+dekar> and buy a new one
2012-06-12T01:42:39 < R2COM> ok
2012-06-12T01:42:50 < R2COM> but one X is not available for sale yet
2012-06-12T01:43:04 <+dekar> so get the nexus galaxy then
2012-06-12T01:43:45 < R2COM> this?
2012-06-12T01:43:46 < R2COM> http://www.t-mobile.com/shop/phones/Cell-Phone-Detail.aspx?cell-phone=T-Mobile-Galaxy-S-II-White
2012-06-12T01:44:05 <+dekar> NEXUS GALAXY
2012-06-12T01:44:09 < R2COM> oh
2012-06-12T01:44:11 < R2COM> ok
2012-06-12T01:44:23 <+dekar> that's the google dev phone
2012-06-12T01:44:27 <+dekar> comes with stock android
2012-06-12T01:44:40 <+dekar> no weird UI shit vendors like Samsung and HTC usually put on top
2012-06-12T01:44:58 < R2COM>          List Price:          $799.99              Price From:                 $0.01 	  (Price varies based on service type)                             You Save:          $799.98 (99%)
2012-06-12T01:44:59 < R2COM> wtf
2012-06-12T01:45:07 < R2COM> oh
2012-06-12T01:45:08 < R2COM> service
2012-06-12T01:45:23 < R2COM> camera only 5MP
2012-06-12T01:45:37 <+dekar> sucks for you
2012-06-12T01:45:43 < R2COM> so it has USB socket, which can go to USB host socket?
2012-06-12T01:45:47 < R2COM> USB plug*
2012-06-12T01:45:49 < R2COM> ?
2012-06-12T01:45:49 <+dekar> well you can still interpolate that up to 50mbit later
2012-06-12T01:45:58 <+dekar> uhm MP
2012-06-12T01:46:01 <+dekar> 50MP
2012-06-12T01:46:26 <+dekar> yeah like all other android devices it supports the android accessory protocol via usb
2012-06-12T01:47:00 < R2COM> then
2012-06-12T01:47:21 < R2COM> all i need to do is, write One driver, which would be universal to all my boards, so they can talk with this phone and get settings/data/etc?
2012-06-12T01:47:32 <+dekar> yeah
2012-06-12T01:47:41 < R2COM> and..lets say after a year i get another similar, but better one
2012-06-12T01:47:46 < R2COM> there wont be much work to remake driver etc?
2012-06-12T01:47:52 <+dekar> no change
2012-06-12T01:47:56 < R2COM> well...
2012-06-12T01:48:02 < R2COM> thats...kind of good
2012-06-12T01:48:07 < R2COM> thanks for the info
2012-06-12T01:48:16 < R2COM> ill look at that stuff
2012-06-12T01:48:23 < blkcat> you can get an unlocked nexus from google play for $400.
2012-06-12T01:48:27 < blkcat> but i'd rather you just bought mine.
2012-06-12T01:49:12 <+dekar> blkcat, why don't you like it?
2012-06-12T01:49:15 < R2COM> yes, i'd pay 401$ for your
2012-06-12T01:49:34 < blkcat> dekar: poor signal where i live.
2012-06-12T01:49:47 < R2COM> hmm
2012-06-12T01:49:55 < R2COM> also i see different carriers support different phones
2012-06-12T01:50:00 < R2COM> not like all support all phones
2012-06-12T01:50:03 <+dekar> R2COM, oh android5 will come up soon, and the nexus galaxy is probably the only phone that will get the update
2012-06-12T01:50:09 <+dekar> all others will have to be sold on ebay
2012-06-12T01:50:26 < R2COM> i wonder who buys them, since they know this product is obsolete
2012-06-12T01:50:49 <+dekar> most people don't seem to understand the numbers
2012-06-12T01:51:01 <+dekar> that's why old iPhones have this insane resell value
2012-06-12T01:51:12 <+dekar> people are like "oh it's an iPhone!"
2012-06-12T01:51:33 < R2COM> i wonder why manufacturers do such shit
2012-06-12T01:51:43 < R2COM> i mean...why not write a code which runs on new and on old shit
2012-06-12T01:51:45 <+dekar> R2COM, what kind of shit? selling products?
2012-06-12T01:51:48 < R2COM> to some degree its possible
2012-06-12T01:51:57 < R2COM> no, like stopping updates
2012-06-12T01:52:03 <+dekar> R2COM, supporting those hacked together kernels is a lot of work
2012-06-12T01:52:10 <+dekar> why would they keep supporting it?
2012-06-12T01:52:15 <+dekar> people already spent the money
2012-06-12T01:52:20 < R2COM> well...
2012-06-12T01:52:25 <+dekar> they don't earn anything by supporting them
2012-06-12T01:52:28 <+izua> hack valuye
2012-06-12T01:52:58 <+izua> which is pretty much the definition of titanical pointless work
2012-06-12T01:54:09 < R2COM> ok
2012-06-12T01:54:43 <+dekar> izua, I hate how all those SoCs (like the qualcomm ones) just aren't supported by any OS. I mean you can install that one hacked together kernel full of precompiled proprietary bits, but that's it. Once you want something new (software wise), the hardware has reached the end of life
2012-06-12T01:55:19 <+dekar> the hardware goes out of production really soon and after that they're just dead
2012-06-12T01:55:37 < blkcat> it's a paradigm shift in the industry
2012-06-12T01:55:44 < blkcat> cheaper to just throw stuff out and buy new than to support the old
2012-06-12T01:55:50 <+dekar> they basically manufacture ARM SoCs to have them end up in trash
2012-06-12T01:55:59 < R2COM> blkcat: turns out that yes
2012-06-12T01:56:05 < R2COM> unless one has lots of time for such shit
2012-06-12T01:56:09 < R2COM> but
2012-06-12T01:56:13 < R2COM> new stuff is expencive
2012-06-12T01:56:17 <+dekar> I just think it's an incredibly waste
2012-06-12T01:56:23 < blkcat> it is.
2012-06-12T01:56:25 <+izua> ^
2012-06-12T01:56:26 <+dekar> *incredible
2012-06-12T01:56:26 < R2COM> but here is another thing!
2012-06-12T01:56:29 < R2COM> if
2012-06-12T01:56:40 <+izua> you could start your own ic factory
2012-06-12T01:56:43 < R2COM> the providers of phone companies, give it for somoe 50$ or so, for those who are on contract
2012-06-12T01:56:46 < R2COM> then its OK?
2012-06-12T01:56:59 < R2COM> i mean...50$ 100$ every year on phone
2012-06-12T01:57:01 < R2COM> not that bad
2012-06-12T01:57:13 < R2COM> you dont have to buy unlocked
2012-06-12T01:57:17 <+dekar> R2COM, what? I have a general problem with destroying perfectly working turing complete hardware
2012-06-12T01:57:26 < R2COM> what you mean
2012-06-12T01:57:27 < R2COM> ?
2012-06-12T01:57:30 <+dekar> I have a problem with limiting turing complete hardware to begin with
2012-06-12T01:57:36 < blkcat> it's not the expense, it's the waste of it all
2012-06-12T01:57:37 <+izua> design a similar core to arm, at least, IS compatible, add peripherals, and let anyone with an fpga or asic synthesising capabilities build his own soc or mcu similar to what we design
2012-06-12T01:57:54 <+izua> which of course, can run what we want, and that would be the mainline linux kernel? :P
2012-06-12T01:58:25 <+izua> but of course, probably halfway through that we'll run out of money, most likely after the first batch
2012-06-12T01:58:36 <+dekar> R2COM, those chips are general purpose CPUs, yet we use them as if they were special purpose ASICs, just able to run android version X and not version Y
2012-06-12T01:58:40 <+izua> and it will end in the same pile as rpi and duke nukem
2012-06-12T01:59:08 <+dekar> izua, I'll just buy x86er
2012-06-12T01:59:13 <+dekar> at least till secure boot comes
2012-06-12T01:59:20 < R2COM> right now my primary and only phone is NOkia5100 ;) which i bought in 2003
2012-06-12T01:59:24 < R2COM> no fancy thit
2012-06-12T01:59:28 < R2COM> just reliable
2012-06-12T01:59:29 <+izua> secure boot is going to be so cool
2012-06-12T01:59:47 <+dekar> izua, yeah - crippled linux that can't do shit anymore is so cool
2012-06-12T01:59:56 <+dekar> I can't compile my own modules anymore
2012-06-12T02:00:08 <+dekar> I can't have MY OS boot any other OS I want
2012-06-12T02:00:09 <+izua> and even cooler will be the time when you won't be able to install hardware breakpoints on your machine anymore, and it will be able to run and sign encrypted code
2012-06-12T02:00:29 <+izua> go go gadget drm
2012-06-12T02:00:35 <+dekar> izua, just wait for fully homomorphic encryption
2012-06-12T02:00:42 <+dekar> the holy grail of cryptography
2012-06-12T02:01:01 <+izua> y u no count to infinity instead
2012-06-12T02:01:04 <+dekar> your CPU calculates stuff, but you have mathematically proven no chance of understanding WHAT it actually does
2012-06-12T02:01:32 <+dekar> cause it is actually able to do all calculations through a layer of encryption on encrypted data
2012-06-12T02:01:41 <+dekar> and the data only decrypts itself if it wants to
2012-06-12T02:01:46 <+dekar> turing complete encryption
2012-06-12T02:01:59 <+dekar> now _that's_ fucked up
2012-06-12T02:02:12 <+dekar> would allow for epic cloud computing though
2012-06-12T02:02:13 <+izua> i have no idea what homo encryption is, pardon the pun, but wasn't it theoretical only?
2012-06-12T02:02:28 < R2COM> the android phones have USB 2?
2012-06-12T02:02:30 < R2COM> or USB3?
2012-06-12T02:02:43 <+dekar> izua, there are working implementations of homomorphic crypto already, they're just incredibly slow
2012-06-12T02:02:57 <+izua> let's take this slow. what is homomorphic crypto
2012-06-12T02:03:02 <+dekar> they only support like 3 operations at EXTREME costs, yet they're turing complete
2012-06-12T02:03:20 <+dekar> izua, you have some application, that has been encrypted
2012-06-12T02:03:28 <+dekar> you run it, in its encrypted form
2012-06-12T02:03:32 <+dekar> without knowing the key
2012-06-12T02:03:43 <+dekar> that's homomorphic crypto
2012-06-12T02:03:50 <+izua> neat.
2012-06-12T02:04:04 <+dekar> _if_ the application decides to decrypt parts of it (like a frame it rendered) then it does so
2012-06-12T02:04:11 <+izua> i'm not sure how that is matematically possible though
2012-06-12T02:04:15 <+dekar> but you can't hack the application
2012-06-12T02:04:50 <+izua> but that has a high chance of being used for drm and such
2012-06-12T02:04:55 <+dekar> okay let's take an easy example
2012-06-12T02:04:58 <+dekar> XOR
2012-06-12T02:05:05 <+izua> every mp3 file is an mp3 player instead
2012-06-12T02:05:08 <+dekar> XOR is homomorphic concerning the XOR operation
2012-06-12T02:05:19 <+dekar> you know what a one time pad is right?
2012-06-12T02:05:29 <+izua> and you can only play your mp3 5 times a day
2012-06-12T02:05:35 <+izua> yeah
2012-06-12T02:05:50 <+dekar> okay so I have two numbers 32bit each
2012-06-12T02:05:59 <+dekar> so I have 64bit and I encrypt them with a one time pad
2012-06-12T02:06:03 <+dekar> then I give them to you
2012-06-12T02:06:14 <+dekar> and I tell you to XOR the first number with the second
2012-06-12T02:06:18 <+dekar> and pass the result to me
2012-06-12T02:06:28 <+dekar> you don't know which numbers you XOR'ed
2012-06-12T02:06:40 <+dekar> but I can now decrypt them with the one time pad
2012-06-12T02:06:49 <+dekar> and get the result of the calculation you performed
2012-06-12T02:07:05 < R2COM> i cant find if those phone support usb3 or 2?
2012-06-12T02:07:07 < R2COM> anyone knows?
2012-06-12T02:07:13 <+dekar> R2COM, they don't
2012-06-12T02:07:18 < R2COM> just USB2?
2012-06-12T02:07:19 <+izua> usb3 has sort of a bigger jack
2012-06-12T02:07:29 < R2COM> USB2 High Speed?
2012-06-12T02:07:36 <+dekar> izua, were you able to follow me?
2012-06-12T02:07:37 <+izua> and it's widely unimplemented, i only seen it on MSC and some very expensive hubs
2012-06-12T02:07:39 <+izua> dekar: yeah
2012-06-12T02:07:47 <+dekar> izua, you see how it works?
2012-06-12T02:07:59 <+izua> yeah, i got it before your example though :)
2012-06-12T02:08:05 <+dekar> k
2012-06-12T02:08:15 <+izua> but that can probably be used for more bad stuff than good
2012-06-12T02:08:18 <+dekar> RSA is another partially homomorphic algorithm
2012-06-12T02:08:25 <+dekar> I can encrypt 2 numbers with RSA
2012-06-12T02:08:27 <+dekar> pass them to you
2012-06-12T02:08:32 <+dekar> and you can multiply them for me
2012-06-12T02:08:40 <+dekar> and return them without ever knowing the content
2012-06-12T02:09:01 <+dekar> izua, it's the perfect copy protection
2012-06-12T02:09:09 < karlp> bloody hell, this is one hell of a lot of scrollback to say the same thing over and over and over and over
2012-06-12T02:09:13 <+dekar> it also is the perfect trust anchor for cloud computing
2012-06-12T02:09:19 < karlp> no-one mentioned openwrt?
2012-06-12T02:09:24 < BrainDamage> I tought there's no homomorphic encryption for operations only
2012-06-12T02:09:36 < karlp> they have 3.3 for most socs, but they're not targetting socs with graphics :)
2012-06-12T02:09:37 <+dekar> BrainDamage, what do you mean?
2012-06-12T02:09:53 <+dekar> BrainDamage, RSA is homomorphic for multiplications
2012-06-12T02:09:59 <+dekar> and XOR is homomorphic for XOR
2012-06-12T02:10:02 < BrainDamage> I mean for all operations
2012-06-12T02:10:03 <+dekar> and there are some others
2012-06-12T02:10:29 < karlp> also, usb3 does NOT have a bigger jack,
2012-06-12T02:10:30 <+dekar> BrainDamage, there are fully homomorphic algorithms, they don't support _all_ operations, but enough to be turing complete
2012-06-12T02:10:36 < karlp> onl yif you want to support some of the higher speed an dhigher power modes
2012-06-12T02:10:53 <+dekar> BrainDamage, like some older ARMs couldn't divide in hardware, the compiler would do that in software
2012-06-12T02:11:06 < BrainDamage> I know what turing complete implies
2012-06-12T02:12:02 <+dekar> BrainDamage, the ones that exist somehow corrupt themselves after X operations so they constantly have to re-encrypt their own data to protect themselves from corruption
2012-06-12T02:12:11 <+dekar> idk the details, but it seems like they suck
2012-06-12T02:12:37 <+izua> you're easy to distract, dekar
2012-06-12T02:12:40 < BrainDamage> I am quite glad to it, because I suspect it'd be badly abused in rights-limiting way
2012-06-12T02:12:44 <+izua> or you have a very wide array of interests :)
2012-06-12T02:13:00 <+izua> last time i recall raptor codes talk
2012-06-12T02:13:03 <+dekar> izua, I have a really wide array of interests
2012-06-12T02:13:25 < BrainDamage> btw, even subtract and branch if 0 is turing complete
2012-06-12T02:13:38 < BrainDamage> I once made a retarded cpu implementing it in vhdl
2012-06-12T02:13:51 <+dekar> even a turing machine is turing complete, it still sucks :)
2012-06-12T02:13:51 < BrainDamage> the compiler wasn't exactly fun tough :s
2012-06-12T02:14:11 <+dekar> lol why would you do that? XD
2012-06-12T02:14:17 <+izua> BrainDamage: that's what i'm saying, homomorphic encryption has very little useful properties than can be useful for an everyday user - at least imo
2012-06-12T02:14:23 <+dekar> useless exercise
2012-06-12T02:14:44 <+dekar> izua, imagine all your applications running in the cloud
2012-06-12T02:14:48 <+izua> they're the perfect pitch for copy protection, as dekar said, until the major cpu won't be x86 anymore or it will evolve to the point that has no hardware breakpoints and can run signed and encrypted code
2012-06-12T02:14:51 < BrainDamage> dekar: it was a challenge
2012-06-12T02:14:53 <+dekar> yet you can be sure it is perfectly safe
2012-06-12T02:15:06 < BrainDamage> in retrospective, I paid myself 3€/h
2012-06-12T02:15:18 < BrainDamage> but I won the bet :p
2012-06-12T02:15:22 <+izua> there's always someone with a bigger computer that can brute force everything - at least that's what i try to believe
2012-06-12T02:15:24 <+dekar> izua, so I do think that can be pretty useful
2012-06-12T02:15:40 <+dekar> izua, you're wrong, brute force my one time pad
2012-06-12T02:15:41 <+izua> BrainDamage: did you end up poorer or wealthier?
2012-06-12T02:15:53 < BrainDamage> wealthier
2012-06-12T02:16:09 < BrainDamage> the money was from the bet, divide the time wasted on it
2012-06-12T02:16:22 <+dekar> izua, I did tell you that I implemented brute-force based FEC since I couldn't be fucked understanding the algorithm, didn't I?
2012-06-12T02:16:24 <+izua> you can't have otps for everything, that's not how it works in the real world
2012-06-12T02:16:32 <+izua> yeah, i recall :)
2012-06-12T02:16:37 <+dekar> it actually worked
2012-06-12T02:16:40 <+izua> with all the childbirth paging messages
2012-06-12T02:16:47 <+izua> yeah, you showed me a transcript. epic.
2012-06-12T02:16:51 <+dekar> yeah those
2012-06-12T02:17:03 <+izua> something about a cop inspecting a raw sewage plant?
2012-06-12T02:17:06 <+izua> i recall gestank :D
2012-06-12T02:17:14 <+dekar> so brute force is a solution to some problems
2012-06-12T02:17:17 <+dekar> but not to all :)
2012-06-12T02:17:32 <+dekar> it only generated 2.5% cpu load while decoding in realtime
2012-06-12T02:17:50 <+izua> that implies a otp big enough for all your apps though
2012-06-12T02:18:17 <+dekar> izua, I have some tritium in my keyring, I will use the decay to generate entropy :)
2012-06-12T02:18:37 <+dekar> actually a few GB of entropy isn't much of a problem these days
2012-06-12T02:18:54 <+dekar> also you can just AES or something like that as a secure PRNG
2012-06-12T02:19:07 <+dekar> 128bit seed is enough
2012-06-12T02:19:12 < BrainDamage> actually hw isn't that secure nowdays
2012-06-12T02:19:20 < BrainDamage> chip hacking are getting common and common
2012-06-12T02:20:41 < karlp> ie, money talks.
2012-06-12T02:20:47 < karlp> it doesn't matter how they did it.
2012-06-12T02:21:17 < feurig> yeah and cypress is still 8051 based.
2012-06-12T02:21:21 < feurig> bahhh.
2012-06-12T02:21:24 < karlp> hehe
2012-06-12T02:21:33 < karlp> 8051 is still uber cheap
2012-06-12T02:21:37 < karlp> unfortunately,
2012-06-12T02:22:09 < feurig> and lots of us geezers grew up on it.
2012-06-12T02:22:13 <+dekar> uber cheap ftl, I prefer high margin business
2012-06-12T02:22:23 < BrainDamage> I've seen rf chips with micro cores
2012-06-12T02:22:40 < BrainDamage> it was not 8086, but something similar
2012-06-12T02:22:42 < feurig> (the same way that basic is still around because the dinosaurs knew basic)
2012-06-12T02:22:45 < BrainDamage> it was awful to see
2012-06-12T02:23:14 < BrainDamage> ( still x86 )
2012-06-12T02:23:24 < feurig> but the only compiler thats open source is sdcc so you might as well use something equally psychotic like a pic.
2012-06-12T02:23:46 < karlp> dekar: I'm not saying I wanted to be making them.
2012-06-12T02:24:01 <+dekar> karlp, I actually meant using them
2012-06-12T02:24:14 <+dekar> if your margin is big enough you just don't care
2012-06-12T02:24:19 < karlp> indeed.
2012-06-12T02:24:22 < karlp> that's why I'm not using them
2012-06-12T02:24:34 < karlp> but people send me things and go, "hey, but there's some 8051 code already done"
2012-06-12T02:24:48 < karlp> and margins don't last forever
2012-06-12T02:25:02 < BrainDamage> for the same reason, fortran is still widely used in the physics community
2012-06-12T02:25:07 < feurig> u g ly you aint got no alibi your just ....
2012-06-12T02:25:16 < feurig> uhhg 8051

2012-06-12T06:08:05 < upgrdman> do you know what a breadboard is?
2012-06-12T06:08:25 <+izua> flyback-: olimex is prototyping one with a ethernet, it has an arduino pinout (among others)

2012-06-12T06:17:09 <+izua> i'm working with some TV IR receivers

2012-06-12T06:17:55 <+izua> out of all CFLs, the cheapest one is incredibly noise in pretty much all the spectrum
2012-06-12T06:18:10 <+izua> well, not the cheapest one, the smallest one, which happened to be almost the cheapest

2012-06-12T06:19:23 < dongs> upgrdman: who the FUCK uses breadboards in 2012, and if you really want to you can just jumper the fucking ports with 1:1 wires into your "breadboard"

2012-06-12T06:21:22 < R2COM> heh
2012-06-12T06:22:04 < R2COM> but sometimes it happens some stuff is available in DIP only
2012-06-12T06:22:11 < R2COM> or one would go with it due to price etc..
2012-06-12T06:22:17 < upgrdman> "targeting the Chinese market where a lot of low cost goods are still assembled by hand using PTH parts" is it really cheaper for the chinese to hand solder them?
2012-06-12T06:22:37 < dongs> for chinese, yes
2012-06-12T06:22:45 < dongs> you can just go out in the street and gather some teenage girls
2012-06-12T06:22:50 < dongs> and make them solder
2012-06-12T06:23:01 < R2COM> only solder? and thats it?

2012-06-12T06:38:42 < zippe> As for latency; it's not that bad

2012-06-12T06:45:22 < zippe> The GHI gadgeteer stuff is also really well thought out
2012-06-12T06:45:55 < R2COM> when i'll be rich, i'll buy microsoft and shut it down. No more microsoft. No more Windows.

2012-06-12T17:05:51 < marienz> BrainDamage: I'm in western europe, but it looks like I can postorder one for about 10 euros
2012-06-12T17:05:55 < Laurenceb> ^pmsl
2012-06-12T17:06:39 < BrainDamage> if you have to order one, you can get better price / power ratio with a f4 discovery board
2012-06-12T17:07:04 < BrainDamage> for 16€, you get a _really_ powerful chip, and some extras like an accelerometer, etc
2012-06-12T17:07:34 < marienz> actually, the accelerometer would come in handy for the one silly little thing I might use something like this for
2012-06-12T17:08:03 < marienz> which is to tape it to the back of my monitor so my pc knows if it's in portrait or landscape
2012-06-12T17:08:34 < dongs> i think a tarduino will do that job jsut fine
2012-06-12T17:08:44 < dongs> you dont need 168mhz processor tellign you if its facing up or down
2012-06-12T17:09:32 < marienz> absolutely, but it looks like an arduino is actually more expensive than a board like this one
2012-06-12T17:09:37 < BrainDamage> fun thing is that a tarduino costs more than a f4 discovery
2012-06-12T17:09:55 < BrainDamage> not to mention that you'd have to buy an accelerometer too
2012-06-12T17:10:17 < marienz> IIUC the main thing arduino would buy me is ease of use programming, which I don't really need (it'll just take me longer, but I'm not in a hurry and don't mind having to learn on the programming side of things)
2012-06-12T17:10:49 < marienz> if this thing has an accelerometer already on the board that's pretty hard to beat for me
2012-06-12T17:12:27 < karlp> BrainDamage: libopencm3 is lgpl now, so it's not nearly as awkward as before when it was gpl
2012-06-12T17:12:35 < BrainDamage> oh awesome
2012-06-12T17:14:48 < karlp> indeed
2012-06-12T17:14:54 < karlp> so, I started usign it.
2012-06-12T17:15:02 < karlp> and immediately felt more productive than with stdperiph lib
2012-06-12T17:15:16 < dongs> for me, it was the other way around
2012-06-12T17:15:17 < karlp> but part of that was makefiles all nciely done for me .)
2012-06-12T17:15:31 < karlp> dongs: I just hadn't had enough done with stdperiph lib for it to really matter
2012-06-12T17:15:34 < marienz> it's a bit like the f4 discovery being a reasonably-priced accelerometer I can plug into a usb port, with a microcontroller and a ton of additional connectivity thrown in as a bonus
2012-06-12T17:15:49 < karlp> more likely, I'd used stdperiph enough to learn _how_ to use either of them.
2012-06-12T17:16:07 < dongs> i tried libopencm3 and they renamed every ISR, added some useless makefile shit, I had to use THEIR linker scripts, they renamed every register from what it was called in stdperiphlib, AND half the stuff I needed to use wasn't implemented.
2012-06-12T17:16:58 < dongs> also the project dir now had like 100 directories for different s hit
2012-06-12T17:17:05 < dongs> stdperiph/cmsis is in 2 dirs

2012-06-12T17:23:25 < karlp> renaming the ISRs I agree was a bad idea, I+m not sure why they thought that was a good idea.
2012-06-12T17:23:42 < karlp> the linker script is unfortunately always tied to the startup code though.
2012-06-12T17:24:10 < dongs> ive used their warez with my own linker/startup
2012-06-12T17:24:20 < dongs> but I had to hack shit up for renamed ISRs
2012-06-12T17:24:22 < dongs> annoying

2012-06-12T18:14:58 <+dekar> BrainDamage, or even newlib? the newlib license is uber permissive
2012-06-12T18:15:35 < BrainDamage> yeah, I didn't phrase that correctly
2012-06-12T18:15:47 < BrainDamage> I shouldn't have used even
2012-06-12T18:16:29 <+dekar> also LGPL is still weird, you have to provide your compiled object files to the customer and give them a way to flash modified firmwares
2012-06-12T18:17:05 <+dekar> BSD style licenses (like newlib) are usually no problems for corporations, anything GPL is probably restricted
2012-06-12T18:17:07 < jpa-> yeah, LGPL for embedded is a bit annyoing
2012-06-12T18:17:26 <+dekar> GPL does a ton of stuff like giving permission to use your companies IP for free
2012-06-12T18:17:59 <+dekar> we only use LGPL for internal tools at our company
2012-06-12T18:18:13 < jpa-> do you have a reference on that?
2012-06-12T18:18:26 < jpa-> i.e. how widely does it apply anyway
2012-06-12T18:18:39 <+dekar> jpa-, on what? GPL licensing your IP as well?
2012-06-12T18:18:58 < Laurenceb> gpl is funny
2012-06-12T18:19:10 <+dekar> "Finally, every program is threatened constantly by software patents. States should not allow patents to restrict development and use of software on general-purpose computers, but in those that do, we wish to avoid the special danger that patents applied to a free program could make it effectively proprietary. To prevent this, the GPL assures that patents cannot be used to render the program non-free."
2012-06-12T18:19:14 < Laurenceb> "we support free software.... here are a ton of conditions"
2012-06-12T18:19:15 <+dekar> http://www.gnu.org/copyleft/gpl.html
2012-06-12T18:20:03 <+dekar> so whenever you license something under the GPL to a customer you also license your patents used by that software to them
2012-06-12T18:20:13 < BrainDamage> https://en.wikipedia.org/wiki/WTFPL
2012-06-12T18:20:15 < jpa-> ah, of course
2012-06-12T18:20:25 <+dekar> I started using CC0 actually
2012-06-12T18:20:40 <+dekar> for my private projects at least
2012-06-12T18:20:58 < jpa-> we don't even really have software patents around here, fortunately
2012-06-12T18:21:02 <+dekar> it makes sure that wherever you live, you license it the most permissive way possible
2012-06-12T18:21:26 <+dekar> jpa-, I still think it is wrong to be forced to license your patents for free
2012-06-12T18:21:37 <+dekar> I mean companies pay for patents
2012-06-12T18:21:42 < jpa-> not really, for GPL anyway
2012-06-12T18:21:57 <+dekar> overall I am pro patents, I think they make sure companies disclose all their inventions
2012-06-12T18:21:58 < jpa-> otherwise you could just patent it and cheat around GPL
2012-06-12T18:22:22 <+dekar> and after the patent protection end, all their proprietary technology is documented (patent paper) and freely available
2012-06-12T18:22:32 <+dekar> I have read patents to implement stuff several times
2012-06-12T18:22:52 <+dekar> jpa-, I don't consider that cheating, but w/e
2012-06-12T18:22:59 <+dekar> I guess I just don't agree with the GPL
2012-06-12T18:23:21 <+dekar> I think licensing some software under an open source license while parts of it implement patents is perfectly fine
2012-06-12T18:23:31 <+dekar> people can wait 18 years till the patent protection end
2012-06-12T18:23:35 <+dekar> or pay and use it right now
2012-06-12T18:24:00 <+dekar> we all use FFMPEG etc, that is covered under a ton of patents
2012-06-12T18:24:27 < jpa-> yeah, but just don't use GPL for those and be happy
2012-06-12T18:24:45 < karlp> dekar: no, you have to provide your objects and a way for them to recompile, _on demand_
2012-06-12T18:24:46 <+dekar> the FFMPEG authors can't give us licenses for the patents they used to implement the codecs anyway
2012-06-12T18:25:04 <+dekar> karlp, not recompile, rather link
2012-06-12T18:25:07 < jpa-> dekar: but they promise *they* don't sue
2012-06-12T18:25:07 <+dekar> but yeah
2012-06-12T18:25:21 < karlp> also, patent handover is gplv3 only
2012-06-12T18:25:25 <+dekar> jpa-, who doesn't sue?
2012-06-12T18:25:31 < jpa-> ffmpeg authors
2012-06-12T18:25:39 < jpa-> they can't do anything about other people, obviously
2012-06-12T18:25:46 <+dekar> jpa-, they don't OWN the patents anyway
2012-06-12T18:25:50 <+dekar> so how would they sue?
2012-06-12T18:27:04 < jpa-> dekar: it applies to the patents *if* they owned any
2012-06-12T18:27:32 < jpa-> it's really just a way to stop people circumventing GPL
2012-06-12T18:28:17 < jpa-> if you don't like GPL, you won't like things that make GPL more secure
2012-06-12T18:28:17 <+dekar> jpa-, it's a way to prevent companies from using the GPL, they can "circumvent" the GPL by using a BSD license
2012-06-12T18:28:46 <+dekar> yeah I feel like the GPL is limiting my personal freedom
2012-06-12T18:29:03 < jpa-> eh, i mean "circumvent GPL" as in "take GPL software developed by someone else, add propietary part to achieve vendor lock-in, sell for profit"
2012-06-12T18:29:14 <+dekar> when I release a modified android kernel, then I have to also post the source for it. if I lose the source, then I can get sued over it
2012-06-12T18:29:35 <+dekar> so I rather not, I feel like the GPL is potentially dangerous to me
2012-06-12T18:30:05 < jpa-> i guess you live in the USA where ridiculous lawsuits cost millions?
2012-06-12T18:30:33 <+dekar> that stuff could backfire years later, like someone downloads my modified kernel now and sues me in 50 years when I don't have the source anymore
2012-06-12T18:30:34 < jpa-> i haven't heard anyone getting in trouble for actually losing the source code, it's quite a remote chance
2012-06-12T18:30:45 <+dekar> nope I live in germany where lawsuits are reasonable
2012-06-12T18:30:51 < jpa-> dekar: you only need to provide source for 3 years after distributing
2012-06-12T18:31:03 <+dekar> jpa-, only for 3 years? are you sure?
2012-06-12T18:31:18 <+dekar> I guess I missed that when reading the GPL
2012-06-12T18:31:37 < jpa-> valid for at least three years and valid for as long as you offer spare parts or customer support for that product model
2012-06-12T18:31:47 <+dekar> jpa-, yeah in any case they could probably only charge me for the work needed to hack those 3 lines I changes themselves
2012-06-12T18:32:07 <+dekar> *I changed
2012-06-12T18:32:36 <+dekar> so that would probably be like 100€ and not significant
2012-06-12T18:32:48 < jpa-> also "force majeure" could apply if you actually lose the source code accidentally
2012-06-12T18:32:59 <+dekar> I guess so
2012-06-12T18:33:18 <+dekar> also they could argue I was careless
2012-06-12T18:33:23 <+dekar> didn't do backups
2012-06-12T18:33:26 < jpa-> true
2012-06-12T18:33:39 <+dekar> well I just feel my freedom is limited
2012-06-12T18:33:44 <+dekar> don't like it, and thus avoid it
2012-06-12T18:33:53 <+dekar> I have one GPL project on github
2012-06-12T18:34:06 <+dekar> but I will probably strip the GPL stuff and make it a small CC0 project
2012-06-12T18:34:12 <+dekar> probably a single gnu radio plugin
2012-06-12T18:35:38 < jpa-> i guess time will show how much GPL / non-GPL matters for the eventual success of open source projects.. both have advantages and drawbacks
2012-06-12T18:37:06 <+dekar> jpa-, I have a router that allows me to officially open a root telnet shell via a simple code I can enter to my phone (it does SIP as well)
2012-06-12T18:37:17 <+dekar> they didn't do that cause they were forced
2012-06-12T18:38:09 <+dekar> I don't think I need GPL to enforce my access to device, I believe in a free market and I can pick open devices if I want to
2012-06-12T18:38:16 <+dekar> *devices
2012-06-12T18:40:49 < pelrun> put the source and the binary in one zip, done.
2012-06-12T18:40:58 < pelrun> then you lose all or none of it
2012-06-12T18:41:08 <+dekar> jpa-, I actually wonder… the secure boot stuff is coming up and distributions like fedora (probably ubuntu as well) plan to have their bootloader signed by microsoft, doesn't that void the GPL if they don't give me as their user a way to boot my own kernel etc?
2012-06-12T18:41:09 < jpa-> it doesn't matter if you lose the binary
2012-06-12T18:41:24 -!- emeb [~ericb@ip72-223-81-94.ph.ph.cox.net] has joined ##stm32
2012-06-12T18:41:40 <+dekar> pelrun, people may still have the binary only, and then you have to give them the source
2012-06-12T18:41:50 < jpa-> dekar: there have been discussions - who cares, there is a bios option you can enable
2012-06-12T18:42:14 < pelrun> if you're not actively distributing the binary, then you're off the hook
2012-06-12T18:42:16 <+dekar> jpa-, there _may be_ a bios option
2012-06-12T18:42:25 <+dekar> that's up to the vendors, not mandatory
2012-06-12T18:42:34 < jpa-> not really clear yet
2012-06-12T18:42:40 < jpa-> crappy system anyway if there is not
2012-06-12T18:43:15 <+dekar> microsoft made clear that the option to disable is is allowed on x86, whereas on ARM secure boot is mandatory and mustn't be disabled
2012-06-12T18:43:57 < pelrun> yeah well they're dicks anyway
2012-06-12T18:44:06 < pelrun> and they're hardly going to get a monopoly on arm devices
2012-06-12T18:44:10 <+dekar> I am pretty sure some vendors won't disable it, I mean why risk having the customer brick the mainboard?
2012-06-12T18:44:33 < pelrun> and it'll get cracked at some point
2012-06-12T18:44:35 <+dekar> same for android, many devices are locked due to warranty reasons
2012-06-12T18:44:58 <+dekar> pelrun, might be cracked, will get updated
2012-06-12T18:45:05 <+dekar> it can only be cracked so often
2012-06-12T18:45:35 < pelrun> many devices are locked because the vendors want control
2012-06-12T18:45:42 < pelrun> not really for warranty
2012-06-12T18:46:09 < pelrun> certainly, if recovering from a bad upload was simple, then warranty wouldn't be an issue anyway
2012-06-12T18:46:33 <+dekar> pelrun, so many people bricked their android devices
2012-06-12T18:46:36 < pelrun> but they just want you to preferentially buy a new phone than extend the life of an old one
2012-06-12T18:46:58 < pelrun> yeah, because they don't bother making them brickproof
2012-06-12T18:47:04 < pelrun> which is pretty bloody easy to do
2012-06-12T18:47:04 <+dekar> ofc they want, I would want that if I were them
2012-06-12T18:47:15 <+dekar> selling more means earning more money
2012-06-12T18:47:44 < pelrun> in fact, being unbrickable is *trivial*, so it's almost fraudulent that they make them so fragile
2012-06-12T18:48:19 <+dekar> pelrun, I disagree on the fraudulent
2012-06-12T18:48:36 <+dekar> bios updates were known to possibly brick PC hardware as well
2012-06-12T18:48:48 < pelrun> and then they fixed that
2012-06-12T18:48:49 <+dekar> vendors just don't feel like investing much time on that
2012-06-12T18:49:17 < pelrun> I don't think you can readily get a mainboard that doesn't have a read-only failsafe bios of some sort
2012-06-12T18:49:18 <+dekar> pelrun, they fixed that? only for some over clocker main boards with like dual bios and stuff
2012-06-12T18:49:24 < pelrun> nah, bollocks
2012-06-12T18:49:53 <+dekar> idk, haven't updated a bios in quite a while
2012-06-12T18:49:59 <+dekar> bit I have seen them brick
2012-06-12T18:50:11 < pelrun> when you reflash they only update the second half of the flash rom
2012-06-12T18:50:14 <+dekar> around 2005 was probably the last time I've seen it go wrong
2012-06-12T18:50:41 <+dekar> more memory costs more money
2012-06-12T18:50:56 < pelrun> it's trivially cheap now
2012-06-12T18:51:12 <+dekar> pelrun, why do you think there are so many different stm32f1?
2012-06-12T18:51:27 < pelrun> that's different
2012-06-12T18:51:32 <+dekar> once you mass produce that stuff matters
2012-06-12T18:51:45 < pelrun> and even there, there's a RO bootloader in every stm32 that can't be overwritten
2012-06-12T18:52:04 <+dekar> yeah and you can external reflash like every bios chip
2012-06-12T18:52:18 < pelrun> but it's been a long time since even the smallest bios flash chips are multiples of the maximum bios binary size
2012-06-12T18:52:19 <+dekar> and use JTAG to recover your phones after your bricked them
2012-06-12T18:52:28 < pelrun> why would you need jtag?
2012-06-12T18:52:46 <+dekar> cause you fucked up and it crashed after deleting the whole flash
2012-06-12T18:53:03 < pelrun> you have either a separate mask rom with a first stage bootloader in it
2012-06-12T18:53:08 <+dekar> I agree that they could make it secure, but they didn't
2012-06-12T18:53:23 <+dekar> people are free to buy different phones
2012-06-12T18:53:49 < pelrun> the thing is, such a bootloader is so small that it doesn't cost you anything to install it
2012-06-12T18:53:52 <+dekar> I'd go for the nexus line, they have unlocked bootloaders without bricking risk
2012-06-12T18:54:11 < pelrun> and it reduces the cost of repairing/replacing bricked devices
2012-06-12T18:54:21 <+dekar> I don't believe in forcing vendors, I think the free market can self-regulate
2012-06-12T18:54:28 < pelrun> yeah, like with cars?
2012-06-12T18:54:39 < BrainDamage> it's not a free market
2012-06-12T18:54:42 < pelrun> there's a reason the government puts safety regs in place
2012-06-12T18:55:07 < pelrun> because if it was truly free, companies would happily kill you if it made them a few more cents
2012-06-12T18:55:20 < pelrun> as it is there are plenty of ways they do that already
2012-06-12T18:55:35 <+dekar> well whatever, I live in germany and americans tell me it's communism over here all the time
2012-06-12T18:56:02 < pelrun> and in germany, you've got incredibly strict safety standards already
2012-06-12T18:56:07 < pelrun> not to mention the CE stuff
2012-06-12T18:56:07 < BrainDamage> it's not even comunism, most of the UE is more like socialist
2012-06-12T18:56:08 <+dekar> I know
2012-06-12T18:56:35 < pelrun> and it's why german engineering is so good
2012-06-12T18:56:38 <+dekar> yeah we CE tested our stm32 product :)
2012-06-12T18:57:15 < pelrun> whereas america has put banking as their highest-priority business action
2012-06-12T18:57:16 <+dekar> I guess saving peoples lives should be important and regulations make sense for that
2012-06-12T18:57:17 < pelrun> morons
2012-06-12T18:57:24 <+dekar> make sure your water bottles don't poison you etc
2012-06-12T18:57:38 <+dekar> but I feel like phone bootloaders shouldn't be regulated
2012-06-12T18:57:54 < pelrun> regulations are the only way to get corporations to behave as ethical actors
2012-06-12T18:58:06 < Laurenceb> not really
2012-06-12T18:58:13 <+dekar> the EU did regulate charging connectors, phones made here _must_ have micro-usb now. that's wrong imo
2012-06-12T18:58:15 < Laurenceb> if people dont buy their products
2012-06-12T18:58:21 < pelrun> dekar: SERIOUSLY?
2012-06-12T18:58:23 < Laurenceb> i didnt know that
2012-06-12T18:58:25 < pelrun> that's like the best thing ever
2012-06-12T18:58:32 < pelrun> I can't believe you think that sucks
2012-06-12T18:58:39 < blkcat> how is that wrong?
2012-06-12T18:58:45 < blkcat> interoperability is awesome.
2012-06-12T18:59:01 < pelrun> the whole "every phone a new connector just to force you to re-buy every accessory" is an awful state of affairs

2012-06-12T18:59:27  * pelrun raises eyebrow
2012-06-12T18:59:47 < BrainDamage> it's 6, if he was at work, he could've left
2012-06-12T19:00:44 < BrainDamage> btw, I prefer with unlocking option too, I hate when my freedoms are restricted
2012-06-12T19:00:55 < pelrun> ok, you miss my meaning
2012-06-12T19:01:02 < pelrun> it's not about locking down the firmware
2012-06-12T19:01:28 < Laurenceb> unlocking option is good
2012-06-12T19:01:40 < Laurenceb> but forcing it toi be sold with that would be stupid
2012-06-12T19:01:42 < pelrun> it's about making a first-stage bootloader that's unbreakable, that *facilitates* restoring the entire firmware
2012-06-12T19:01:51 < pelrun> no bogus 'security' or anything
2012-06-12T19:01:57 < Laurenceb> same for usb
2012-06-12T19:02:13 < BrainDamage> why the usb connector is stupid?
2012-06-12T19:02:17 < pelrun> then you're free to do whatever you want, and it's easy to repair
2012-06-12T19:02:25 < Laurenceb> what if i want a waterproof phone
2012-06-12T19:02:29 < BrainDamage> btw, the regulation requires it to be micro-usb compatible
2012-06-12T19:02:34 < BrainDamage> not micro usb micro usb
2012-06-12T19:02:50 < BrainDamage> I have a phone with a connector which is not micro usb. yet a micro usb can be plugged in
2012-06-12T19:02:53 < pelrun> companies would rather you don't have that freedom, and make the thing fragile so that it can easily brick if you try to exercise those freedoms
2012-06-12T19:02:57 < Laurenceb> i should be free to buy whatever connector i want
2012-06-12T19:03:01 < pelrun> that's the sort of thing that should be regulated away
2012-06-12T19:03:13 < Laurenceb> some companies
2012-06-12T19:03:17 < Laurenceb> like apple would
2012-06-12T19:03:24 < Laurenceb> thats why i dont buy apple
2012-06-12T19:03:30 < BrainDamage> you're not free to hook any rf endpoint to the cell network for instance
2012-06-12T19:03:33 < BrainDamage> it has to be approved
2012-06-12T19:03:39 < pelrun> Laurenceb, but as a consumer you shouldn't be forced to buy 15 different chargers and usb cables for every different phone you buy
2012-06-12T19:04:03 < BrainDamage> the charger change afaik was done to amount of chargers in the landfills
2012-06-12T19:04:14 < pelrun> absolutely, the waste is atrocious
2012-06-12T19:04:23 < Laurenceb> i guess it makes sense, but i dont see how it should be compulsory
2012-06-12T19:04:29 < Laurenceb> maybe a tax incentive or similar
2012-06-12T19:04:46 < Laurenceb> based on the environmental damage
2012-06-12T19:04:51 < pelrun> like I said, it's the best way to get corporations to behave ethically
2012-06-12T19:06:16 < pelrun> taxes are good for giving a financial incentive to improve the way companies do business
2012-06-12T19:06:38 < pelrun> but it's not much good in terms of standardisation
2012-06-12T19:06:53 < Laurenceb> standardisation isnt always good
2012-06-12T19:07:07 < pelrun> behaving like a sack of cats isn't either
2012-06-12T19:07:16 < Laurenceb> say i want a specialist phone
2012-06-12T19:07:22 < Laurenceb> micro usb might not be best
2012-06-12T19:07:33 < BrainDamage> you can add any other connector
2012-06-12T19:07:53 < Laurenceb> anyway ive got better things to think about
2012-06-12T19:08:27 < pelrun> a connector choice is one of the most trivial things in the design of a product
2012-06-12T19:08:55 < pelrun> not to mention having everyone use microusb means volumes can go up and production prices then go down
2012-06-12T19:09:12 < pelrun> so it's ridiculous to argue against it in the general case
2012-06-12T19:10:01 < Laurenceb> sure
2012-06-12T19:10:14 < Laurenceb> thats why tax incentives would be ok
2012-06-12T19:10:17 < Laurenceb> as a general case
2012-06-12T19:10:30 < Laurenceb> regulation means you _cant_ do something different
2012-06-12T19:10:41 < Laurenceb> which is stupid and oppressive

2012-06-13T12:35:28 < iR0b0t1> pelrun: If you see it done it is usually to reduce heat dissipation, not to increase current capacity.
2012-06-13T12:36:01 < iR0b0t1> (as in, each the bank of FETs never encounters more than the max current for a single FET)

2012-06-13T12:38:19 < iR0b0t1> Not exactly. The FETs never turn on at the same time, so at least one FET will carry the full load for a few ns or so.

2012-06-13T18:21:27 <+dekar> Laurenceb, is BGA hard to do? I imagined you just use some flux and heat it with hot air till it's done. Haven't done it yet though
2012-06-13T18:21:41 < Laurenceb> thats my plan
2012-06-13T18:21:54 < Laurenceb> i havent done anything this small before, and ive got a headache today

2012-06-13T19:17:08 < Laurenceb> ok
2012-06-13T19:17:09 < Tectu> and modify CHIBIOS path  (Arround line 60, somewhere)
2012-06-13T19:17:25 < Tectu> then everything works from wherever your project is located
2012-06-13T19:17:55 < Tectu> just do the including of the other files as needed then in   SRCINC   and LIBINC

2012-06-13T20:56:53 < karlp> hrmm, dma worked fine teh first time I tried it, now no dice.
2012-06-13T20:56:56 < karlp> blocking it is then
2012-06-13T20:58:23 <+Steffanx> Why PoE seems to be so relatively complex?
2012-06-13T20:59:20 < BrainDamage> because lan cables tend to be long and moderately high resistive
2012-06-13T20:59:35 <+Steffanx> Compared to a simple ethernet/power split cable (fake PoE)
2012-06-13T20:59:44 < BrainDamage> plus it has to be rather idiot proof
2012-06-13T20:59:59 < karlp> either end can be the supply side, so they need to negotiate
2012-06-13T21:00:35 <+Steffanx> but still
2012-06-13T21:02:29 < karlp> dma to a really slow uart will only write each byte as the uart becomes available right?
2012-06-13T21:03:31 <+Steffanx> Isn't that the idea of dma?

2012-06-13T21:50:38 < Laurenceb_> well first of all i need to undersant how texane works when flashing
2012-06-13T21:50:49 < Laurenceb_> i pasted the texane output here earlier

2012-06-13T22:17:16 < Laurenceb_> hmmm
2012-06-13T22:17:43 < Laurenceb_> so, it erases the first block, then says its flashed it, but gets verify error on byte 0x00

2012-06-14T01:52:16 < zippe> And I only have ~3.5k of heap free (of 8k)
2012-06-14T01:53:04 < zippe> On the bigger systems like the F4 it's wicked having a shell and a filesystem and all the mod cons

2012-06-14T02:17:40 < szczys> I can't figure out if it's my program, or the programmer that's the issue

2012-06-14T02:55:24 <+dekar> zippe, when I had nuttx it running on one of my stm32f1 (20kb ram) I only had around 8kb heap left
2012-06-14T02:56:18 <+dekar> and I had weird memory fragmentation issues, after starting "sleep 10 &" a few times my total ram was less than after reboot
2012-06-14T02:56:46 <+dekar> the shell was quite cool, but overall I wasn't too convinced
2012-06-14T02:56:56 < zippe> dekar: RAM consumption depends a lot on your config
2012-06-14T02:57:04 < zippe> stacks, features, preallocated stuff
2012-06-14T02:57:14 <+dekar> zippe, I wanted it all! :D
2012-06-14T02:57:14 < dongs> zippe: ever got anywhere with FY shit?
2012-06-14T02:57:22 < zippe> Really it's a bit beefy for the F1x devices.  64K of RAM and it's much better
2012-06-14T02:57:37 < zippe> dongs: I got your stuff all compiling, then I got sidetracked
2012-06-14T02:57:42 < dongs> ok good
2012-06-14T02:57:50 < zippe> I need to build a programming cable
2012-06-14T02:58:01 < dongs> i'm sure wiring up transfoermer wire to 0.5mm pins for SWD isn't high on your priority/enjoyment list
2012-06-14T02:58:04 < dongs> right
2012-06-14T02:58:25 < dongs> I think you can clear out the chip from serial bootloader
2012-06-14T02:58:52 < dongs> infact that might be a good idea at first as it blocks jtag as soon as it powers up. i had to  do some manual reset line holding on jlink to get it to chip erase
2012-06-14T03:05:21 < Rickta59> does the program you are trying to use work with the texane stuff szczys?
2012-06-14T03:05:46 < szczys> No?
2012-06-14T03:05:54 < szczys> Maybe
2012-06-14T03:06:09 < szczys> I've compiled a few of the samples for the F0 (from the texane repo)
2012-06-14T03:06:15 < Rickta59> is it something complicated or just a simple thing
2012-06-14T03:06:16 < szczys> but there's a warning that many of those samples don't work
2012-06-14T03:06:24 < szczys> Complicated
2012-06-14T03:06:39 < Rickta59> maybe start with something simple to see if it is the programmer or the program'
2012-06-14T03:06:40 < szczys> I've ended up tailoring a makefile to build the demo in the STM firmware package
2012-06-14T03:06:54 < szczys> The problem is I have zero experience with ARM
2012-06-14T03:07:00 < szczys> so I'm not sure what simple things will work
2012-06-14T03:07:12 < szczys> intitially I got a simple blink program to work by loading it in RAM
2012-06-14T03:07:14 < Rickta59> maybe just blink and led in a loop with a delay
2012-06-14T03:07:21 < szczys> but since I've erase the flash memory this will no longer work
2012-06-14T03:07:45 < szczys> I was thinking that I probably need code in Flash to configure the system clock
2012-06-14T03:07:50 < szczys> does that sound right?
2012-06-14T03:08:02 < Rickta59> probably more like the interrupt vector is empt
2012-06-14T03:08:05 < Rickta59> empty
2012-06-14T03:08:37 < Rickta59> the interrupt vector is used with your first startup to figure out what the stack ptr should be set to
2012-06-14T03:08:42 < Rickta59> do you have another board?
2012-06-14T03:09:04 < Rickta59> you might want to copy an existing board with st-flash
2012-06-14T03:09:10 < Rickta59> copy the code
2012-06-14T03:09:14 < Rickta59> and then write it back
2012-06-14T03:09:20 < Rickta59> on the one that doesn't wor4k
2012-06-14T03:09:36 < Rickta59> can you connect with gdb?
2012-06-14T03:09:42 < Rickta59> and look at what is at 0x00000
2012-06-14T03:09:46 < Rickta59> dissassemble
2012-06-14T03:09:49 < szczys> Yes, I can connect with GDB
2012-06-14T03:10:01 < Rickta59> what is at address 0x0000
2012-06-14T03:10:04 < szczys> any idea the command for pulling down the zero register?
2012-06-14T03:10:19 < Rickta59> pulling down the zero register?
2012-06-14T03:10:31 < szczys> you asked what is at address 0
2012-06-14T03:10:39 < szczys> I'm unsure how to use gdb
2012-06-14T03:10:40 < Rickta59> ah .. just disassemble it
2012-06-14T03:10:55 < Rickta59> let me start it up so i can talk more intelligently
2012-06-14T03:11:03 < szczys> thanks!
2012-06-14T03:12:16 < Rickta59> I'm actually new to this myself .. so i need to poke around
2012-06-14T03:17:07 < Rickta59> hmm .. i'm more used to the gdb with the 430 ..
2012-06-14T03:17:39 < Rickta59> and the sad thing is i did the other day without a problem
2012-06-14T03:17:48 < Rickta59> so i started up st-util
2012-06-14T03:17:51 < Rickta59> it finds my f0
2012-06-14T03:17:58 < Rickta59> i then use the blink directory
2012-06-14T03:18:04 < Rickta59> and typed
2012-06-14T03:18:12 < Rickta59> arm-non-eabi-gdb foo.elf
2012-06-14T03:18:25 < Rickta59> that is the code I've been messing with
2012-06-14T03:18:34 < Rickta59> it loads it into memory a
2012-06-14T03:18:37 < szczys> sure
2012-06-14T03:18:38 < szczys> yep
2012-06-14T03:18:43 < szczys> but that's just ram
2012-06-14T03:18:46 < szczys> not the flash memory
2012-06-14T03:18:51 < Rickta59> i thought the other day i was able to use
2012-06-14T03:18:59 < Rickta59> disassemble 0x8000001
2012-06-14T03:19:10 < Rickta59> which then would show me what is at 0x000 ..
2012-06-14T03:19:38 < szczys> right
2012-06-14T03:19:47 < szczys> I think that's a disassembly from the .elf file
2012-06-14T03:19:49 < Rickta59> when i did that ..
2012-06-14T03:19:54 < szczys> it's not actually reading from the chip
2012-06-14T03:19:56 < Rickta59> i was able to see the stack ptr
2012-06-14T03:20:11 < Rickta59> i did start it
2012-06-14T03:20:15 < Rickta59> and interrupt
2012-06-14T03:20:24 < Rickta59> it is sitting in the code running
2012-06-14T03:20:49 < szczys> right but the texane stlink project doesn't have support for writing to flash
2012-06-14T03:20:55 < szczys> I've been working on it...
2012-06-14T03:21:02 < Rickta59> i thought that is what st-flash does? no?
2012-06-14T03:21:04 < szczys> got so far as to get it to erase the flash
2012-06-14T03:21:14 < szczys> Not for STM32F0 yet
2012-06-14T03:21:18 < szczys> it works for the other discovery boards
2012-06-14T03:21:33 < Rickta59> k .. i hadn't tried i've been focused on what is supposed to go in the linker
2012-06-14T03:21:34 < szczys> for now, the F0 boards are only able to write to RAM, not to FLASH memory
2012-06-14T03:21:51 < dongs> where teh fuck is my free f0
2012-06-14T03:21:52 < szczys> So I'm trying out OpenOCD right now
2012-06-14T03:21:55 < dongs> i signed up but with wrong address
2012-06-14T03:21:58 < Rickta59> got it
2012-06-14T03:22:00 < dongs>  id didnt expect them to ship it to jp
2012-06-14T03:22:03 < dongs> but apparently they did
2012-06-14T03:22:17 < szczys> @dongs: that sucks
2012-06-14T03:22:39 < szczys> @dongs: can you stop by the address and knock on the door?
2012-06-14T03:23:05 < Rickta59> well if it doesn't write than what i was going to suggest isn't going to work
2012-06-14T03:23:17 < Rickta59> i could at least capture the file if you are interested
2012-06-14T03:23:33 < Rickta59> if you only have one board
2012-06-14T03:23:39 < szczys> So if you power cycle yours it still runs the demo that shipped with it?
2012-06-14T03:23:44 < Rickta59> yeah
2012-06-14T03:23:51 < szczys> what OS do you use?
2012-06-14T03:23:56 < Rickta59> linux .. ubuntu
2012-06-14T03:24:15 < szczys> Well, I'd love it if you fired up OpenOCD and grabbed a copy of the flash memory
2012-06-14T03:24:26 < szczys> but it's a bit of work and you might not want to waste the time
2012-06-14T03:24:27 < Rickta59> what does openocd run on?
2012-06-14T03:24:36 < szczys> all platforms
2012-06-14T03:24:41 < szczys> but I've just compiled it on Ubuntu
2012-06-14T03:24:41 < Rickta59> i'm pretty sure i can grab it with st-flash
2012-06-14T03:24:49 < szczys> oh, sure
2012-06-14T03:24:55 < szczys> if you want to give it a try that would be great
2012-06-14T03:24:57 < Rickta59> what .. maybe that is what i did the other day
2012-06-14T03:25:15 < Rickta59> i might have grabbed it and used the arm objcopy to disassemble not gdb
2012-06-14T03:26:18 < Rickta59> how big do you think the demo object code is?
2012-06-14T03:26:44 < Rickta59> the other day i was only looking at the interrupt table so i just grabbed a little
2012-06-14T03:27:36 < szczys> I really don't know
2012-06-14T03:27:44 < szczys> the .bin file I compiled is...
2012-06-14T03:27:55 < szczys> 4.5k
2012-06-14T03:28:03 < szczys> the .elf is 109k
2012-06-14T03:28:16 < szczys> but these don't work so I could be way off.
2012-06-14T03:28:32 < zyp> szczys, isn't adding F0 support just about getting the id to be recognized, then adding F0 specific flash reg addr, flash unlock code and flashing procedure?
2012-06-14T03:28:38 < Rickta59> http://pastebin.com/hWqitx0c
2012-06-14T03:28:43 < Rickta59> that is the interrupt table
2012-06-14T03:29:15 < Rickta59> 99d .. seems to be the highest handler function
2012-06-14T03:29:16 < szczys> zyp: Not quite... there's flash loader code
2012-06-14T03:29:23 < szczys> zyp: written in assembly
2012-06-14T03:29:50 < szczys> zyp: it looks like OpenOCD uses the same loader code for F1 and F0 but I can't get that to work with stlink package
2012-06-14T03:30:17 < Rickta59> are you fine with just a bin file that you can use?
2012-06-14T03:30:41 < zyp> szczys, right, I assumed you wanted it to work withou flashloader first
2012-06-14T03:30:52 < szczys> Rickta59: yeah, a .bin would be great
2012-06-14T03:31:09 < szczys> zyp: yep... loading into RAM seems to work just fine
2012-06-14T03:31:19 < zyp> szczys, I wrote the F4 flashloader that's in the texane repo now
2012-06-14T03:31:32 < szczys> zyp: ah, cool
2012-06-14T03:31:33 < zyp> it should not be that hard to adapt to F0
2012-06-14T03:31:44 < szczys> zyp: I found what OpenOCD uses
2012-06-14T03:31:57 < szczys> zyp: then compiled it, disassembled it, and translated that to hex just like the other loaders
2012-06-14T03:32:10 < zyp> some register bits might be different, and you'd have to replace the thumb2 instructions with normal thumb

2012-06-14T03:38:44 < zyp> i.e. the part of the code that sets up the registers before running the flashloaders
2012-06-14T03:38:46 < szczys> zyp: yes
2012-06-14T03:39:11 < szczys> That's where I think I'm going wrong
2012-06-14T03:39:21 < szczys> I get stuck in that is_core_halted loop
2012-06-14T03:39:22 < dongs> wat is orig.zip?
2012-06-14T03:39:24 < szczys> and it times out

2012-06-14T03:40:25 < zyp> szczys, so, do you know which registers your flashloader is using and for what?
2012-06-14T03:40:33 < dongs> o
2012-06-14T03:40:44 < szczys> zyp: no, I have no idea
2012-06-14T03:40:50 < szczys> I took that code from OpenOCD:

2012-06-14T03:41:12 < zyp> ok, then that's definitely your problem
2012-06-14T03:41:20 < Rickta59> well at least that answers the question i had the other day ; ) .. "does it work with the f0 board"
2012-06-14T03:41:26 < zyp> ah, says it all there
2012-06-14T03:42:04 < szczys> As far as I can tell (from debug messages)
2012-06-14T03:42:14 < szczys> the loader gets written to ram just fine
2012-06-14T03:42:28 < szczys> but once it tries to run it
2012-06-14T03:42:33 < zyp> do you see the params comment in the assembly source file?
2012-06-14T03:42:40 < szczys> yes
2012-06-14T03:42:42 < zyp> that is how the loader is using the registers
2012-06-14T03:42:53 < szczys> how can I translate that to the C file in stlink?
2012-06-14T03:43:00 < zyp> and the part of the code that I linked to is responsible for getting those registers right
2012-06-14T03:44:00 < szczys> oh, I see
2012-06-14T03:44:05 < zyp> you can think of it as a function signature
2012-06-14T03:44:14 < szczys> I get lost because of the C++ type of function/method assignment
2012-06-14T03:44:16 < zyp> you have to call it with the arguments in the correct order
2012-06-14T03:44:25 < szczys> I'm unfamiliar with that and don't know where to look in the code for how it works
2012-06-14T03:44:42 < zyp> huh?
2012-06-14T03:44:43 < Rickta59> stlink_write_reg(sl, target, 0); /* target */
2012-06-14T03:44:51 < Rickta59> 0 in that context is r0?
2012-06-14T03:44:54 < szczys> sl->backend->core_id(sl);
2012-06-14T03:44:55 < zyp> yes
2012-06-14T03:45:00 < szczys> zyp: sorry, I'm off topic
2012-06-14T03:45:17 < zyp> Rickta59, that sets r0 = target
2012-06-14T03:45:44 < Rickta59> so to use that flash loader you have to fill in the registers to match that loader and expected values
2012-06-14T03:45:53 < zyp> exactly
2012-06-14T03:46:19 < Rickta59> * r0 - flash base (in), status (out) ...
2012-06-14T03:46:35 < Rickta59> * r1 - count (halfword-16bit)
2012-06-14T03:47:03 < Rickta59> stlink_write_reg(sl, fl->buf_addr, 0); /* source  .. r0*/
2012-06-14T03:47:12 < zyp> and if you don't want to use the GPLed flashloader from openocd, adapting my F4 one to F0 shouldn't be that hard
2012-06-14T03:47:16 < zyp> it's less complex
2012-06-14T03:47:25 < Rickta59> stlink_write_reg(sl, count, 1); /* count (32 bits words) r1 */
2012-06-14T03:47:49 < zyp> flash base is the base addr of the flash register block
2012-06-14T03:47:57 < szczys> I still really need some code that will get the demo running again
2012-06-14T03:48:16 < szczys> I can't really test stlink for writing to flash if I don't have code I know works
2012-06-14T03:48:29 < zyp> fl->buf_addr should go into r2 (workarea)
2012-06-14T03:48:43 < Rickta59> goes openocd let you load that link i provided?
2012-06-14T03:48:49 < Rickta59> s/g/d/
2012-06-14T03:48:53 < zyp> szczys, sure you can
2012-06-14T03:49:12 < zyp> as long as it flashes and verifies fine, you can flash any data
2012-06-14T03:49:38 < Rickta59> was that the right thing for me to grab so he can get back to square one?
2012-06-14T03:50:06 < Rickta59> "./st-flash read orig.bin 0x08000000 16384" .. or is there more than that needed
2012-06-14T03:51:11 < zyp> Rickta59, hexdump it and check
2012-06-14T03:51:30 < Rickta59> http://pastebin.com/hWqitx0c .. that is the start of it
2012-06-14T03:51:35 < zyp> empty flash reads as 0xff, so you should have a bunch of that in the end of your file
2012-06-14T03:51:41 < Rickta59> ah .. ok
2012-06-14T03:52:02 < zyp> if not, you likely didn't read as far as the empty area
2012-06-14T03:52:17 < Rickta59> 0004560 e7fe e7fe e7fe e7fe e7fe e7fe e7fe e7fe
2012-06-14T03:52:17 < Rickta59> *
2012-06-14T03:52:17 < Rickta59> 0004620 e7fe e7fe e7fe e7fe e7fe e7fe e7fe 0000
2012-06-14T03:52:17 < Rickta59> 0004640
2012-06-14T03:52:23 < Rickta59> that is at the end
2012-06-14T03:53:36 < zyp> huh?
2012-06-14T03:53:47 < dongs> 0xdeadfeed
2012-06-14T03:54:00 < zyp> 16384 should be 0x4000
2012-06-14T03:54:32 -!- peabody124 [~peabody12@128.249.96.21] has joined ##stm32
2012-06-14T03:54:44 < szczys> yeah, I can write and verify that .BIN file (using OpenOCD) at 0x08000000 but the program doesn't run
2012-06-14T03:54:49 < szczys> (no blinking lights, etc)
2012-06-14T03:54:55 < szczys> so I don't think that's the bin file i needed
2012-06-14T03:54:56 < Rickta59> did you unplug/replug
2012-06-14T03:55:18 < szczys> voila
2012-06-14T03:55:20 < szczys> works
2012-06-14T03:55:27 < szczys> you're much smarter than I
2012-06-14T03:55:30 < Rickta59> you have to power cycle
2012-06-14T03:55:32 < szczys> thanks!
2012-06-14T03:55:43 < szczys> so, now I know it's possible
2012-06-14T03:55:46 < Rickta59> well i'm not just selfish ; )
2012-06-14T03:55:52 < Rickta59> what hardware do i need for openocd?
2012-06-14T03:55:59 < szczys> none
2012-06-14T03:56:03 < zyp> nothing special
2012-06-14T03:56:04 < szczys> what you've already got
2012-06-14T03:56:08 < zyp> openocd supports st-link
2012-06-14T03:56:19 < szczys> just get the latest from their git repository
2012-06-14T03:56:22 < szczys> then do:
2012-06-14T03:56:31 < szczys> (hang on)
2012-06-14T03:56:34 < Rickta59> is there any reason to use the texane stuff if that works?
2012-06-14T03:57:07 < szczys> ./bootstrap
2012-06-14T03:57:18 < szczys> ./configure --prefix=/usr --enable-maintainer-mode --enable-stlink
2012-06-14T03:57:19 < szczys> make
2012-06-14T03:57:22 < szczys> sudo make install
2012-06-14T03:57:25 < Rickta59> great thanks
2012-06-14T03:57:30 < szczys> no problem
2012-06-14T03:57:41 < Rickta59> so .. the texane stuff .. if the openocd works why?
2012-06-14T03:57:41 < zyp> Rickta59, that's a question you have to ask yourself
2012-06-14T03:57:46 < szczys> once installed go into the "tcl" directory
2012-06-14T03:57:48 < szczys> and type:
2012-06-14T03:57:57 < szczys> openocd -f board/stm32f0discovery.cfg
2012-06-14T03:58:08 < szczys> you can connect through GDB on port 333
2012-06-14T03:58:10 < zyp> I find openocd to be a lot more complex to get going
2012-06-14T03:58:18 < szczys> sorry... meant port 3333
2012-06-14T03:58:25 < szczys> zyp: exactly
2012-06-14T03:58:30 < szczys> I would prefer to use stlink
2012-06-14T03:58:32 < szczys> for simplicity
2012-06-14T03:58:33 < Rickta59> i do like the simplicity of the command line stuff .. is openocd only tcl?
2012-06-14T03:58:51 < zyp> only how?
2012-06-14T03:59:03 < Rickta59> do i have to use tcl ui
2012-06-14T03:59:16 < Rickta59> * not even sure if i have it installed
2012-06-14T03:59:22 < szczys> there's no ui
2012-06-14T03:59:28 < Rickta59> k
2012-06-14T03:59:30 < szczys> that's just one of the folders in the git repo
2012-06-14T03:59:45 < szczys> you need to tell it what cfg file to use
2012-06-14T03:59:55 < Rickta59> tcl as in sun gui thing or tcl as in some other acronym
2012-06-14T04:00:01 < szczys> but the example also has some path instructions so you need to start it from the right place
2012-06-14T04:00:07 < szczys> like rick said... it's complicated
2012-06-14T04:00:20 < szczys> but I already knew it worked (just wanted to verify
2012-06-14T04:00:33 < szczys> are you still around zyp?
2012-06-14T04:00:42 < Rickta59> : ) .. well now that you are humming i can just wait for you to get it working
2012-06-14T04:00:51 < szczys> me too
2012-06-14T04:01:01 < zyp> szczys, sure
2012-06-14T04:01:11 < Rickta59> thanks btw .. i saw your post on h-a-d and that is why i got one
2012-06-14T04:01:15 < szczys> I think it would be better to port over your loader code
2012-06-14T04:01:29 < szczys> it's probably just address offsets that are different
2012-06-14T04:01:38 < zyp> probably, then here's what you need to change:
2012-06-14T04:01:39 < szczys> unless there is an instruction that's missing in the F0 chips
2012-06-14T04:01:44 < szczys> (they do have a reduced chipset)
2012-06-14T04:01:53 < szczys> sorry ... * reduced instruction set
2012-06-14T04:02:23 < zyp> yes, line 19 is a thumb-2 instruction I believe
2012-06-14T04:02:31 < zyp> so you need to rewrite that
2012-06-14T04:02:37 < Rickta59> so once that is working will it be possible to write to flash from both gdb and st-flash? or just st-flash
2012-06-14T04:02:57 < zyp> also change line 32 and check that the bit tested in line 19 is correct
2012-06-14T04:03:03 < zyp> Rickta59, both
2012-06-14T04:03:09 < Rickta59> just a load?
2012-06-14T04:03:13 < Rickta59> in gdb
2012-06-14T04:03:14 < zyp> this is common code for both
2012-06-14T04:03:31 < zyp> both st-flash and load in gdb invokes this, yes
2012-06-14T04:03:47 < Rickta59> great thanks
2012-06-14T04:04:13 < szczys> so,
2012-06-14T04:04:24 < szczys> are you calling out lines from the stm32f4.s file?
2012-06-14T04:04:47 < zyp> yes
2012-06-14T04:04:59 < zyp> hmm, is there no F0 flashing manual yet?
2012-06-14T04:05:07 < szczys> ummm
2012-06-14T04:05:11 < szczys> there's a programming manual
2012-06-14T04:05:20 < szczys> but it seems to suck compared to prior families
2012-06-14T04:05:24 < szczys> I've been using RM0091
2012-06-14T04:05:27 < szczys> for most everything
2012-06-14T04:05:33 < zyp> where is the flash registers described?
2012-06-14T04:05:45 < szczys> in RM0091
2012-06-14T04:05:47 < zyp> oh, they are in the reference manual now
2012-06-14T04:05:49 < szczys> (looking up the page)
2012-06-14T04:06:19 < szczys> page 42
2012-06-14T04:06:28 < szczys> 3.2 Flash memory functional description
2012-06-14T04:06:33 < szczys> need a link to the document?
2012-06-14T04:06:35 < zyp> already found it
2012-06-14T04:06:38 < szczys> okay
2012-06-14T04:06:56 < zyp> you have to change line 18 as well, it should now read: ldr r4, [r3, #0x0c]
2012-06-14T04:07:10 < szczys> is this file used during compilation, or just in the repo for reference?
2012-06-14T04:07:11 < zyp> the old one only read the upper 16 bits, now the busy flag is in the lower part
2012-06-14T04:07:17 < zyp> just for reference
2012-06-14T04:07:24 < szczys> I see... that confused me at first
2012-06-14T04:07:40 < szczys> so I used arm-none-eabi-gcc to compile it, then object dump to see what it's doing
2012-06-14T04:07:52 < szczys> is that how you translated it to the array in the C file?
2012-06-14T04:07:57 < zyp> pretty much
2012-06-14T04:08:09 < szczys> I figured I was some kind of moron and doing it the hard way.... heh
2012-06-14T04:08:59 < zyp> it's only a few bytes, so transcribing it by hand is not that much waste of time
2012-06-14T04:09:17 < zyp> but actually compiling it as part of the compilation would be nice for maintenance
2012-06-14T04:12:17 < zyp> szczys, http://paste.jvnv.net/view/9S8h1 <- so, you can start out with this (fixed addr of flash reg), and then you have to replace any thumb-2 stuff that doesn't exist on cortex-m0
2012-06-14T04:13:05 < zyp> I believe you might have to replace tst.w with a register-register comparison
2012-06-14T04:13:05 < szczys> I have almost no idea what I'm doing when it comes to assembly
2012-06-14T04:13:27 < szczys> what is the tst line meant to do (in common terms?)
2012-06-14T04:13:40 < zyp> it's «test»
2012-06-14T04:13:57 < szczys> what is it testing?
2012-06-14T04:14:11 < zyp> it checks equality to a bitmask
2012-06-14T04:14:38 < szczys> yeah... I'm not going to be able to figure that out by myself
2012-06-14T04:14:44 < szczys> is texane good at this stuff?
2012-06-14T04:14:50 < szczys> I'm pretty sure he has one of these boards
2012-06-14T04:14:59 < szczys> If someone can get the loader translated
2012-06-14T04:15:12 < szczys> I think I can get the rest working (now that you explained how it maps to the C file)
2012-06-14T04:15:38 < zyp> http://paste.jvnv.net/view/D3RZd <- this might work
2012-06-14T04:16:01 < zyp> but I don't have any way to test it now
2012-06-14T04:17:47 < zippe> dongs: Hmm.  The bootloader script(s) I'm using trying to talk to the FY20 are failing.
2012-06-14T04:18:03 < dongs> serial?
2012-06-14T04:18:48 < dongs> doesnt shorting boot0 make it go into bootloader mode. then you can use ST Flash Demonstrator or someshit to clear it
2012-06-14T04:18:56 < szczys> zyp: so I should be able to map this the same way as you did for the F4
2012-06-14T04:19:05 < zyp> yes
2012-06-14T04:19:29 < zyp> just keep in mind that you have much less ram, so you have to do much smaller blocks
2012-06-14T04:20:50 < zippe> dongs: Yeah, boot0 strapped high, but it's not behaving
2012-06-14T04:20:56 < zippe> Wonder if they blew some of the OTP bits
2012-06-14T04:21:00 < dongs> no
2012-06-14T04:21:01 < Rickta59> anything special to make arm gdb happy with openocd?
2012-06-14T04:21:09 < zippe> Rickta59: ha!
2012-06-14T04:21:14 < Rickta59> Remote 'g' packet reply is too long: 0000000000000000000000000000000000000000000 ...
2012-06-14T04:21:18 < zyp> zippe, what about boot1?
2012-06-14T04:21:19 < dongs> otp wont affect boootloader
2012-06-14T04:21:20 < Rickta59> then it drops me
2012-06-14T04:21:28 < zippe> Rickta59: which GDB version?
2012-06-14T04:21:41 < Rickta59> 7.3.1
2012-06-14T04:21:43 < zyp> doesn't boot1 choose between ram and bootloader when boot0 is high?
2012-06-14T04:21:43 < zippe> zyp: boot1 should be strapped from what I can tell
2012-06-14T04:21:47 < zippe> Rickta59: That's too new
2012-06-14T04:21:54 < Rickta59> it has probably been a while since i built my gcc
2012-06-14T04:22:05 < Rickta59> too new .. thats a first : )
2012-06-14T04:22:10 < zippe> Rickta59: OpenOCD and gdb disagree violently about how many registers an "arm" device has
2012-06-14T04:22:13 < zyp> zippe, so that it starts bootloader and not ram?
2012-06-14T04:22:16 < Rickta59> i'm using the sat thing
2012-06-14T04:22:30 < zippe> Rickta59: I stopped using openocd because I got tired of patching it
2012-06-14T04:22:35 < szczys> zyp: arm-none-eabi-gcc -c stm32f0.s -o test -mcpu=cortex-m0
2012-06-14T04:22:41 < szczys> gives me some errors
2012-06-14T04:22:48 < zyp> which?
2012-06-14T04:22:56 < szczys> stm32f0.s:15: Error: selected processor does not support Thumb mode `cbz r2,done'
2012-06-14T04:22:56 < szczys> stm32f0.s:24: Error: lo register required -- `add r0,#4'
2012-06-14T04:22:56 < szczys> stm32f0.s:25: Error: lo register required -- `add r1,#4'
2012-06-14T04:22:56 < szczys> stm32f0.s:26: Error: lo register required -- `sub r2,#1'
2012-06-14T04:22:57 < zippe> They refuse to vend a machine description to gdb, so gdb falls back to some v4/v5 default behaviour I think
2012-06-14T04:23:14 < zippe> szczys: -mthumb
2012-06-14T04:23:16 < Rickta59> ic
2012-06-14T04:23:39 < szczys> zippe: same errors
2012-06-14T04:23:41 < Rickta59> * just wanted to have an option .. will just wait to see what happens
2012-06-14T04:23:45 < zippe> szczys:  also -arch=armv6m
2012-06-14T04:23:55 < szczys> isn't this an armv7?
2012-06-14T04:24:06 < zippe> no
2012-06-14T04:24:10 < zippe> m0 is v6m
2012-06-14T04:24:16 < szczys> oh, anyway, same errors
2012-06-14T04:24:21 < zippe> You may need -march=armv6s-m
2012-06-14T04:24:38 < zyp> I guess the problem is that those are thumb2 instructions
2012-06-14T04:25:02 < zyp> plain thumb might not have add and subtract immediates
2012-06-14T04:25:11 -!- fishhead is now known as i8086
2012-06-14T04:25:25 < szczys> you're speaking a different language to me ;-)
2012-06-14T04:25:58 < szczys> leaving out the mcpu stuff lets it go without throwing the add and sub errors
2012-06-14T04:26:05 < szczys> but the cbz error is still there
2012-06-14T04:26:06 < zippe> szczys: I just took zyp's pastie and built it with:
2012-06-14T04:26:07 < zippe> ➜  /tmp  arm-none-eabi-gcc -c -march=armv6s-m -mthumb foo.S

2012-06-14T04:27:22 < szczys> ugh...
2012-06-14T04:28:15 < Rickta59> it is basically just doing a memcopy?

2012-06-14T04:30:41 < Rickta59> * special function register
2012-06-14T04:30:57 < Rickta59> i was trying to figure out what 0x0c is
2012-06-14T04:31:11 < zyp> FLASH_SR is a memory mapped register, 0x0c is the offset of SR into the FLASH register block
2012-06-14T04:31:26 < Rickta59> got it thanks
2012-06-14T04:31:33 < zyp> so it starts at 0x40022000 so FLASH_SR is 0x4002200c
2012-06-14T04:33:02 < szczys> zyp: F0 must use half-words for flash write
2012-06-14T04:33:37 < zyp> then you have to change that as well

2012-06-14T09:04:01 < zippe> It's OK.  I was just trying to work out what had you razzed about the M0, and it's nothing that makes any sort of engineering sense.  q.e.d.
2012-06-14T09:05:02 < zippe> so you want to use the M0 instead of the M3 because… someone else is too cheap?
2012-06-14T09:05:44 < zippe> You can benefit from using a chip that's been well-shaken out and understood, with a toolchain that's settled and plenty of testing time on it
2012-06-14T09:06:07 < zippe> Conversely, you win little or nothing by using the m0

2012-06-14T09:25:48 < zippe> Yeah, still working out what it "should" be like.  Ok, so accel actually seems ON
2012-06-14T09:25:50 < zippe> er, OK
2012-06-14T09:26:09 < zippe> 1G reads as about 375 "units" on the Z axis when flat on the table
2012-06-14T09:26:16 < dongs> right. the rate units are totally wrong.
2012-06-14T09:26:18 < dongs> thats where you come in :)
2012-06-14T09:26:28 < dongs> there's acc_1G which you can set
2012-06-14T09:26:31 < zippe> The artificial horizon widget is all kinds of messed up
2012-06-14T09:26:44 < dongs> did you move the stuff while powering it up
2012-06-14T09:26:58 < dongs> it needs to sit perfectly still for the first few seconds while you powert it up
2012-06-14T09:27:05 < dongs> or else gyro offsets will be all wrong
2012-06-14T09:27:35 < zippe> ah, hard to do with this pile of wire on the dsk
2012-06-14T09:27:57 < dongs> if you want to update to R164
2012-06-14T09:28:03 < dongs> i added gyro cal while acc cal
2012-06-14T09:28:10 < dongs> so you can hit htat acccal button and zero out offsets
2012-06-14T09:28:22 < dongs> before it could only be done by stick combo

2012-06-14T12:30:02 < Tectu> some STM32 do have "direct USB" right? where you can just route the USB plug to the STM32 with two resistors, right?
2012-06-14T12:30:28 < Tectu> my development board has some chip (CH376T) which is connected over SPI1 to my STM32F103... what is that for?
2012-06-14T12:31:41 < Tectu> ah, that's for host USB, g guess
2012-06-14T12:31:43 < Tectu> I guess*
2012-06-14T12:31:55 < Tectu> the other USB port is directly connected to USB_DM and USB_DP

2012-06-14T13:09:01 < dongs> i might actually find a use for that here.

2012-06-14T13:40:17 < Tectu> dongs, is it "hard" to use that usb chip?
2012-06-14T13:40:27 < Laurenceb> where do you configure the mcu in chibios?
2012-06-14T13:40:41 < Tectu> Laurenceb, in Makefile there is the included LD file
2012-06-14T13:40:45 < Tectu> search for  *ld
2012-06-14T13:40:50 < Laurenceb> ah
2012-06-14T13:40:55 < Tectu> *.ld should work
2012-06-14T13:41:01 < Tectu> somewhere at line 50 i guess
2012-06-14T13:42:00 < dongs> Tectu: I would imagine 10x easier than dealing with being a usb host/device/parsing fatfs/sd/usb sticks/etc
2012-06-14T13:42:28 < Laurenceb> ok thanks
2012-06-14T13:42:38 < Laurenceb> hmm chibios doesnt want to run off HSI  ?
2012-06-14T13:42:43 < Laurenceb> giving compile error
2012-06-14T13:42:48 < dongs> isnt chibios shit
2012-06-14T13:42:50 < dongs> why ar  you using it
2012-06-14T13:42:55 < Laurenceb> #error "HSE not enabled, required by STM32_SW and STM32_PLLSRC"
2012-06-14T13:43:27 < Tectu> Laurenceb, take a look to  halconfig.h  mcuconfig.h  and chconfig.h
2012-06-14T13:43:33 < Laurenceb> ok
2012-06-14T13:44:47 < Laurenceb> hmm thats what i edited
2012-06-14T13:45:04 < Laurenceb> i want to run off HSI
2012-06-14T13:45:53 < Tectu> did you take a demo like I said or tried to write the whole thing up yourself?
2012-06-14T13:47:39 < Laurenceb> took the discovery demo
2012-06-14T13:47:53 < Laurenceb> it loads now but wont run
2012-06-14T13:48:00 < Laurenceb> as it needs an xtal
2012-06-14T13:49:17 < Tectu> wtf dude
2012-06-14T13:49:21 < Tectu> discovery demos cannot not run
2012-06-14T13:49:26 < Tectu> you're doing it wrong!
2012-06-14T13:49:38 < dongs> he is always doing things wrong :p
2012-06-14T13:51:09 < Laurenceb> the demo needs an external xtal
2012-06-14T13:51:18 <+Steffanx> I don't think you have to help him to remember that dongs :P

2012-06-14T14:01:30 < Tectu> dongs, awesome how you don't find anything related to that chip
2012-06-14T14:01:44 < Tectu> Laurenceb, discovery demo runs on discovery board.

2012-06-14T14:02:16 < Laurenceb> i want to run on my board
2012-06-14T14:02:32 < Tectu> and now you want HSI?
2012-06-14T14:02:50 < Tectu> go to mcuconf.h
2012-06-14T14:03:02 < Tectu> set HSE_ENABLED FALSE
2012-06-14T14:03:10 < Tectu> makse sure HSI_ENABLED is TRUE
2012-06-14T14:03:14 < Tectu> there you go
2012-06-14T14:04:46 < dongs> Tectu: first google link is a pdf.
2012-06-14T14:05:00 < Tectu> i am reading that dongs
2012-06-14T14:05:04 < Tectu> awesome how there isn't anymore than that
2012-06-14T14:05:15 < dongs> thre is
2012-06-14T14:05:19 < dongs> its on manufacturer's site
2012-06-14T14:05:21 < dongs> wch.cn or whatever
2012-06-14T14:05:38 < dongs> Tectu: did that shit come wiht your waveshare kit
2012-06-14T14:05:38 <+Steffanx> I'm sure it's not whatever
2012-06-14T14:05:46 <+Steffanx> As 'whatever' isn't a valid domain
2012-06-14T14:05:50 < Tectu> why cant asian people use readable letters like the rest of the fucking world
2012-06-14T14:06:07 < Tectu> dongs, yep, directly soldered on the board, that biatch
2012-06-14T14:06:19 <+Steffanx> Tectu life is hard isn't it?
2012-06-14T14:06:27 < Tectu> Steffanx, no here
2012-06-14T14:06:39 < dongs> i might have to buy it from them next time
2012-06-14T14:06:45 < dongs> i got a useless usb3300 breakout from them
2012-06-14T14:06:47 < dongs> after making my own
2012-06-14T14:06:52 < Laurenceb> ./ChibiOS/os/hal/platforms/STM32F4xx/hal_lld.h:875:2: error: #error "HSE not enabled, required by STM32_SW and STM32_PLLSRC"
2012-06-14T14:06:54 < dongs> and theirs has more feautres
2012-06-14T14:07:46 < Tectu> dongs, looks like that biatch is to use as easy as taking a crap
2012-06-14T14:08:08 < Tectu> awesome no-sense sentense
2012-06-14T14:08:24 <+Steffanx> :)
2012-06-14T14:08:38 < dongs> takin a crap is pretty easy where im from
2012-06-14T14:08:52 < Tectu> dongs, that's what i am saying...
2012-06-14T14:09:02 < Tectu> chip just got some registers where you write in some values
2012-06-14T14:09:06 < Tectu> and read out some other registers
2012-06-14T14:09:08 < Tectu> finished.
2012-06-14T14:16:02 < Laurenceb> arg wtf
2012-06-14T14:16:16 < Laurenceb> i need to change the pll settings
2012-06-14T14:16:21 < Laurenceb> thats the problem
2012-06-14T14:16:44 < Laurenceb> how should i change M,N,P,Q  ?
2012-06-14T14:18:51 < dongs> use the excel tool??
2012-06-14T14:19:24 < Tectu> dongs, w00t?
2012-06-14T14:19:27 < Laurenceb> ewww
2012-06-14T14:19:46 < dongs> wat
2012-06-14T14:23:21 < Laurenceb> it wont run
2012-06-14T14:30:00 < Laurenceb> ha it runs
2012-06-14T14:30:09 < Laurenceb> used datasheet to work out pll settings
2012-06-14T14:31:15 < Laurenceb> but systick is way too fast
2012-06-14T14:32:26 < Tectu> dongs, USB OTG cannot handle USB sticks 'nd shit?
2012-06-14T14:34:18 < Laurenceb> wait no its running correctly
2012-06-14T14:34:24 < Laurenceb> but gpio is being weird
2012-06-14T14:34:37 < dongs> Tectu: of course it ca n but then you have to handle all teh shit
2012-06-14T14:34:52 < Laurenceb> how do you init gpio in chibios?
2012-06-14T14:35:22 < Tectu> dongs, is that CH376 shit used often? don't find any european distributor
2012-06-14T14:35:29 < Tectu> Laurenceb, you don't
2012-06-14T14:35:34 < Tectu> Laurenceb, take a look to the board files
2012-06-14T14:35:38 < Laurenceb> http://pastebin.com/XiEUQyFK
2012-06-14T14:35:40 < Tectu> board.h/board.c
2012-06-14T14:36:20 < Laurenceb> oh crap
2012-06-14T14:36:31 < Laurenceb> this is more complex than it looks
2012-06-14T14:36:45 < dongs> Tectu: its 100% chink shit.
2012-06-14T14:36:53 < dongs> i asked my suppliers about it, im sure waveshare will sell it to you as well
2012-06-14T14:37:17 < Tectu> dongs, does that shit work properly or is it just some half-working shit copy clone of some else shit?
2012-06-14T14:37:25 < dongs> they generaly work
2012-06-14T14:37:29 < Tectu> Laurenceb, it's not, when you see through it
2012-06-14T14:37:30 < dongs> they have a clone of ftdi
2012-06-14T14:37:31 < dongs> lol
2012-06-14T14:37:34 < dongs> usb>serial
2012-06-14T14:37:43 < Tectu> lol
2012-06-14T14:37:50 < Tectu> Laurenceb, you should read documentation first.
2012-06-14T14:37:51 < Laurenceb> so i need board.c and .h  ?
2012-06-14T14:38:16 < Tectu> Laurenceb, damn boy, read documentation
2012-06-14T14:38:20 < Tectu> Laurenceb, inside your makefile
2012-06-14T14:38:24 < Tectu> arround line +60
2012-06-14T14:38:41 < Tectu> there is some  include=$(CHIBIOS)/boards/foooo/board.mk
2012-06-14T14:38:44 < Tectu> go to that directory
2012-06-14T14:38:49 < Tectu> open the board.h file
2012-06-14T14:38:55 < Tectu> configure your pins
2012-06-14T14:39:38 < Tectu> i recommend to write a board file up from scratch for your board
2012-06-14T14:39:40 < Tectu> isn't that hard
2012-06-14T14:39:49 < Tectu> takes 1 hour, everything works from now on
2012-06-14T14:40:10 < dongs> whyt do pepople use chibios anyway
2012-06-14T14:40:13 < dongs> its too bloated
2012-06-14T14:40:23 < Tectu> dongs, because it works
2012-06-14T14:40:28 < Tectu> at least sometimes....
2012-06-14T14:40:29 < dongs> apparently it doesn't
2012-06-14T14:40:34 < Tectu> and it's open sauce
2012-06-14T14:40:34 < dongs> or else Laurenceb wouldnt be having all this trouble
2012-06-14T14:40:42 < karlp> laurence always has problems though
2012-06-14T14:40:44 < Tectu> he just didn't read documentation
2012-06-14T14:40:52 < Tectu> karlp, can't say that i don't ;-)
2012-06-14T14:41:06 < Tectu> i mostly just run into stupid problems
2012-06-14T14:41:08 < Laurenceb> heh
2012-06-14T14:41:13 < Laurenceb> i thought it was simple
2012-06-14T14:41:16 < Laurenceb> its not
2012-06-14T14:41:21 < Tectu> Laurenceb, it is!
2012-06-14T14:41:22 < Tectu> i use it
2012-06-14T14:41:25 < Tectu> it is very simple
2012-06-14T14:41:29 < Tectu> just read the documentation
2012-06-14T14:41:34 < Tectu> takes one hour, then you do whatever you want
2012-06-14T14:42:39 < Laurenceb> k
2012-06-14T14:42:52 < Laurenceb> im going to molest children
2012-06-14T14:43:06 < karlp> as long as you read the docs first :)
2012-06-14T14:43:09 < Laurenceb> ok
2012-06-14T14:43:23 < Tectu> haha
2012-06-14T14:43:36 < Tectu> karlp, sounds like you make fun of me?
2012-06-14T14:43:59  * Laurenceb is lolling at apples pcbs
2012-06-14T14:44:03 < karlp> no, I was using your joke :)
2012-06-14T14:44:10 < Laurenceb> wonder how much time they spent making it all the same color
2012-06-14T14:44:26 < Tectu> Laurenceb, what the hell do you mean?
2012-06-14T14:44:29 < Tectu> the children?
2012-06-14T14:44:32 < Tectu> or the documentation
2012-06-14T14:44:37 < karlp> Laurenceb: what do you mean, all the same colour? aren't most pcbs all the same colour?
2012-06-14T14:45:12 < Laurenceb> http://cdn.macrumors.com/article-new/2012/06/retina_macbook_pro_teardown.jpg
2012-06-14T14:50:18 < Tectu> Laurenceb, how's it going with the children? having trouble?
2012-06-14T14:50:37 < Laurenceb> lolo
2012-06-14T14:53:33 < Laurenceb> do i have to define all the pins?
2012-06-14T14:53:55 < Laurenceb> VAL_GPIOC_MODER  <- what if its zero?
2012-06-14T14:55:56 < Tectu> read the documentation
2012-06-14T14:56:07 < Tectu> seriously, I'd help you if i'd have time
2012-06-14T14:56:10 < Tectu> but i don't i am sorry
2012-06-14T14:56:26 < Tectu> and there is pretty pretty pretty everything documented INSIDE the board.h file :(

2012-06-14T15:25:47 < Tectu> (had the same with my STM32VL)
2012-06-14T15:25:51 < Tectu> well, not really
2012-06-14T15:25:56 < Tectu> just diode fucked up
2012-06-14T15:26:18 < Tectu> was some manufacuturing fail, i guess
2012-06-14T15:26:39 < Laurenceb> OTG_FS_VBUS
2012-06-14T15:26:44 < Laurenceb> is portA-9?
2012-06-14T15:27:09 < Laurenceb> ive tied it to VBUS
2012-06-14T15:27:12 < Laurenceb> is that bad?
2012-06-14T15:27:38 < Tectu> hopefully you don't tie up your girlfriend the wrong way
2012-06-14T15:31:32 < Laurenceb> fig 343
2012-06-14T15:31:33 < Laurenceb> wtf
2012-06-14T15:35:19 < Laurenceb> ill desolder the stm and try again
2012-06-14T15:35:26 <+Steffanx> Yeah, we need pics !
2012-06-14T15:37:33 <+Steffanx> No camera on your phone Laurenceb ?
2012-06-14T15:37:39 <+Steffanx> That will work this time
2012-06-14T15:39:16 < Laurenceb> its actually not too bad
2012-06-14T15:39:31 < Laurenceb> small section of plastic blew off around the F of F405
2012-06-14T15:40:24 < Laurenceb> looks like the VREg is bad
2012-06-14T15:41:01 <+Steffanx> Still nice too see a photo of that
2012-06-14T15:41:31 <+Steffanx> For LaurencebsExperienceWithSTM32.com
2012-06-14T15:43:26 < Laurenceb> its clusterfucked
2012-06-14T15:43:44 < Laurenceb> whole board is fried
2012-06-14T15:43:46 < BrainDamage> you can use a lens in front of the camera if your phone can't focus
2012-06-14T15:43:58 < BrainDamage> like magnifying glass
2012-06-14T15:45:06 <+Steffanx> Laurenceb ^^
2012-06-14T16:02:55 <+Steffanx> Laurenceb, I have a new idea for a kickstarter project ..
2012-06-14T16:03:06 <+Steffanx> So we can buy you a camera :)
2012-06-14T16:03:31 < Tectu> I don't know why, but i feel like saying this:   I like sex
2012-06-14T16:03:38 <+Steffanx> I mean, people donate for a new camera for you (and get photos from your project in return)
2012-06-14T16:03:48 <+Steffanx> Tectu .. grow up :)
2012-06-14T16:04:17 < Tectu> Steffanx, yes, i think the same
2012-06-14T16:06:08 <+Steffanx> Don't hurt your brains
2012-06-14T16:07:12 < Tectu> I am sorry, Steffanx :(
2012-06-14T16:07:14 < Laurenceb> fuuuuu
2012-06-14T16:07:18 < Laurenceb> usb is reversed
2012-06-14T16:07:36 <+Steffanx> Reversed?
2012-06-14T16:08:29 < Laurenceb> yes
2012-06-14T16:08:34 <+Steffanx> How so?
2012-06-14T16:08:42 <+Steffanx> What is reversed?
2012-06-14T16:08:44 < Laurenceb> 1,2,3,4 is 4,3,2,1
2012-06-14T16:08:53 <+Steffanx> Ha
2012-06-14T16:09:05 <+Steffanx> I mean, sorry to hear

2012-06-14T18:19:38 < karlp> nrst from the swd header on the discovery board?
2012-06-14T18:19:49 < karlp> probably not, it's a feature of the stlink2 only,
2012-06-14T18:20:00 < karlp> and I don't remember seeing anyone add any special support for it yet.

2012-06-14T18:20:32 < karlp> openocd has a few extra commands decoded, but you'd have to decided when you wanted to do anything with the pin too.
2012-06-14T18:20:33 < Laurenceb> its odd
2012-06-14T18:20:39 < Laurenceb> my F1 board runs fine
2012-06-14T18:20:49 < Laurenceb> but F4 needs NRST disconnecting
2012-06-14T18:20:49 < karlp> f1 has been around a lot longer, and had more people work on it :)
2012-06-14T18:25:44 < GargantuaSauce> speaking of chibios on the f4, are the sleep functions supposed to be somewhat precisely timed?
2012-06-14T18:26:08 < GargantuaSauce> because i am trying to naively do hobby servo timing and only seem to be getting ~ms precision
2012-06-14T18:26:38 <+Steffanx> Hobby servo timing?
2012-06-14T18:26:49 < GargantuaSauce> "pwm" where the pulse is between 1 and 2 ms
2012-06-14T18:26:49 <+Steffanx> Why you don't use a real timer?
2012-06-14T18:27:00 <+Steffanx> Which is designed for things like this
2012-06-14T18:27:00 < GargantuaSauce> hence the "naively"
2012-06-14T18:27:06 < GargantuaSauce> will try a real solution next :P
2012-06-14T18:27:32 <+izua> did you forget to have the sum of delays constant to 1/50Hz
2012-06-14T18:27:39 < GargantuaSauce> nope
2012-06-14T18:27:57 <+izua> because if you put a pulse of 1ms and then for one clock cycle have the line at 0, and then another 1ms pulse, it doesn't really count
2012-06-14T18:28:07 <+izua> you have to 'fill the gap' to 20ms
2012-06-14T18:28:45 < GargantuaSauce> it's not THAT naive an implementation
2012-06-14T18:28:45 <+izua> well then, make sure tha t_off + t_on = 20ms
2012-06-14T18:28:46 < pelrun_> or you run 8+ channels at once and cycle between them
2012-06-14T18:29:11  * pelrun_ wrote a 12+ channel ppm/pwm input and combined output thingy on the f1
2012-06-14T18:29:21 < GargantuaSauce> yeah this will be 18 eventually
2012-06-14T18:29:25 <+izua> you have a lot of timers on it dude
2012-06-14T18:29:32 < GargantuaSauce> yeah I'll use those next
2012-06-14T18:29:33 <+izua> why waste cycles in software?
2012-06-14T18:29:34 < pelrun_> you only need one
2012-06-14T18:29:46 < GargantuaSauce> because i was pissing around :P
2012-06-14T18:29:51  * pelrun_ is using TIM2 only
2012-06-14T18:29:53 < GargantuaSauce> will do it properly next...thanks
2012-06-14T18:29:54 < GargantuaSauce> gotta run
2012-06-14T18:30:05 <+izua> pelrun_: my best approach to software pwm was using a sorted array of timestamps + masks structs
2012-06-14T18:30:27 < pelrun_> I don't really bother with sorted timestamps
2012-06-14T18:30:31 <+izua> you could toggle all or just a single channel in constant time, every time the software pwm counted up
2012-06-14T18:30:38 <+izua> you could also sort them, i guess :P
2012-06-14T18:30:59 < pelrun_> it's not really needed for rc stuff; each channel is handled sequentially so you just update the output capture for the length of the next channel
2012-06-14T18:31:32 <+izua> that works for 10 channels or so
2012-06-14T18:31:55 < pelrun_> or more, if you don't mind your update rate dropping slightly
2012-06-14T18:32:15 <+izua> i don't mind, it's the crappy rc servo electronics which might.
2012-06-14T18:32:39 < pelrun_> nah, servos have a fairly long timeout before they go 'limp'
2012-06-14T18:32:43 <+izua> hey cool, no more signal! that means i should let the motor coast!
2012-06-14T18:33:31 < pelrun_> have to check that out on the escs though, thanks for the reminder
2012-06-14T18:33:56 < pelrun_> worst case I just split the channels into two bands
2012-06-14T18:34:43 < pelrun_> although the ppm output wouldn't work in that case
2012-06-14T18:38:18 < jpa-> with DMA it is trivial to do e.g. 16-channel PWM on STM32
2012-06-14T18:38:49 < pelrun_> yeah, if all your pins are adjacent
2012-06-14T18:38:58 < pelrun_> grrrr
2012-06-14T18:39:10 < jpa-> well, just in the same port
2012-06-14T18:39:16 < jpa-> throw in more ram and do a second port :P
2012-06-14T18:39:35 < pelrun_> I'm spread across three :P
2012-06-14T18:39:45 < jpa-> aw :/
2012-06-14T18:40:09 < pelrun_> juggling other peripherals *and* the 5v tolerant pins made for some 'fun'
2012-06-14T18:40:39 < pelrun_> (the outputs are also used as inputs, so need to be on the high voltage pins)
2012-06-14T18:41:11 < pelrun_> and I'm using EXTI, so the pin numbers had to be unique >:(

2012-06-14T20:30:08 < zyp> zippe, my i2c code has always been working on F4, but it did hang on error, because the error flags have to be cleared explicitly in the error interrupt handler by writing them to 0
2012-06-14T20:30:35 < zyp> I have fixed it, but not made a commit of that fix, so the latest version in git still hangs on errors
2012-06-14T20:31:04 < zyp> but fixing it is adding a single line writing the status register with error flags to 0
2012-06-14T20:47:43 < zippe> Hmm, current issue for me is the hardware state machine seeming to hang at the end of a transaction
2012-06-14T20:50:42 < jpa-> note to self: if you load the wrong binary, wrong code will run

2012-06-14T22:31:16 < szczys> no, that's beyond my skills

2012-06-14T22:35:02 < szczys> Rickta59: I guessed when I filled in lines 1765-66
2012-06-14T22:35:19 < szczys> don't know what workarea start and workarea end should actually be
2012-06-14T22:35:46 < szczys> also confused about the in/out use of r0
2012-06-14T22:36:14 < Rickta59> i think that means that the return of the function is done in r0
2012-06-14T22:36:20 < Rickta59> in you pass a value
2012-06-14T22:36:28 < Rickta59> the loader code should fill in r0 with the result
2012-06-14T22:36:38 < Rickta59> i think
2012-06-14T22:36:44 < Rickta59> i haven't looked at it that much
2012-06-14T22:36:52 < Rickta59> but is seems that all it is really doing is a memcopy
2012-06-14T22:37:07 < Rickta59> and monitoring the flash write flag
2012-06-14T22:37:19 < Rickta59> and updating another memory address to indicate doneness
2012-06-14T22:38:39 < szczys> you've already discovered more than I have
2012-06-14T22:39:54 < Rickta59> debugging a program that is a debugger is kind of self referential .. gdb st-link .. and then attaching to it with gdb .. hmmm
2012-06-14T22:40:27 < szczys> I've just been using the flash util to do the writing:
2012-06-14T22:40:37 < Rickta59> ok
2012-06-14T22:40:52 < szczys> ./st-flash write ~/compile/orig.bin 0x08000000
2012-06-14T22:41:04 < Rickta59> i was going to use the gdb so i could look at memory at the same time as it is using it
2012-06-14T22:41:09 < Rickta59> look at memory in the device
2012-06-14T22:41:15 < szczys> oh, I see
2012-06-14T22:41:38 < Rickta59> the st-flash is download a chunk of code to the device with it writes
2012-06-14T22:41:50 < Rickta59> so if you are running gbd on the device you can look at what it loaded
2012-06-14T22:41:58 < Rickta59> and then monitor what that routine does
2012-06-14T22:42:03 < Rickta59> wacky really
2012-06-14T22:42:12 < Rickta59> hurts brain thinking about it
2012-06-14T22:43:00 < szczys> good luck
2012-06-14T22:43:13 < Rickta59> yeah i don't expect a quick answer .. but it is something to start with
2012-06-14T22:43:20 < Rickta59> thanks for sharing
2012-06-14T22:43:23 < szczys> I'll be in and out this afternoon but I'll leave this connected
2012-06-14T22:43:51 < szczys> so shout if you have any questions (or breakthroughs)
2012-06-14T22:44:00 < Rickta59> k, will do ..

2012-06-14T23:34:40 <+dekar> zippe, what was the i2c problem on f4?
2012-06-14T23:42:12 < Laurenceb_> its i2c?
2012-06-14T23:42:25 < Laurenceb_> thats the first part of the problem right there
2012-06-14T23:43:04 <+dekar> I don't get it
2012-06-14T23:44:03 < Laurenceb_> i2c is always going wrong
2012-06-14T23:44:34 <+dekar> That's what I had when I was using an FTDI to do I2C, but with the STM32 it works great for me
2012-06-14T23:45:22 <+izua> what you had was horrible
2012-06-14T23:46:00 <+dekar> izua, at some point I re-implemented I2C bit banging it over bare MPSSE XD
2012-06-14T23:46:20 <+izua> iirc, zippe's slaved sucked badly and he always got a nak
2012-06-14T23:46:35 <+izua> slave*
2012-06-14T23:47:34 <+dekar> well my experience is that you have to give the slaves some time (especially after writes) and in some times write only a few bytes at a time
2012-06-14T23:47:52 <+dekar> but those are all parameters for my driver API now
2012-06-14T23:47:57 <+izua> true
2012-06-14T23:48:09 <+izua> sounds neat
2012-06-14T23:48:13 <+izua> does it use busy wait delays
2012-06-14T23:48:15 <+dekar> we just benchmark our I2C slaves for the best settings and save them to our server
2012-06-14T23:48:29 <+izua> so it can halt the whole os while waiting for an ack from the device which in turns waits for the i2c slave?
2012-06-14T23:48:40 <+dekar> izua, it supports both actually, it can either poll the slave or use a hard delay
2012-06-14T23:48:52 <+dekar> some slaves crashed for me on constant polling though
2012-06-14T23:49:20 <+dekar> I just sent a start sequence with the address and once they sent the ack I sent stop for my polling
2012-06-14T23:50:13 <+dekar> izua, what do you mean? my stuff always stays responsible
2012-06-14T23:50:35 <+dekar> usb has high priority interrupts on my device, it just reports that it is still busy
2012-06-14T23:50:55 <+dekar> also the driver is used in a worker thread so it doesn't block anything
2012-06-14T23:51:14 <+izua> you suck at programming then
2012-06-14T23:51:21 <+izua> you should use a hardcoded busy wait delay in your windows driver
2012-06-14T23:51:36 <+izua> this way, by halting the whole system, the user will know the computer is working, so it won't mess with it
2012-06-14T23:51:51 <+izua> alternatively, you can also thrash the hdd a bit, so the led and noise should tell him to stay away :D
2012-06-14T23:51:58 <+dekar> izua, last but not least the hardware has an I2C timeout you can set, so if the slave fails to answer in time I reset it
2012-06-14T23:52:09 <+izua> that's neat
2012-06-14T23:52:19 <+dekar> some slaves get stuck in weird ways, like pulling both I2C lines down
2012-06-14T23:52:21 <+izua> and this interface you speak of, is only for the transceivers?
2012-06-14T23:52:26 <+dekar> in that case we power-reset the slave
2012-06-14T23:52:26 <+izua> yeah
2012-06-14T23:52:41 <+izua> you can probably keep a database or something, with exhibited behaviour of tested parts
2012-06-14T23:52:52 <+dekar> izua, yeah we do
2012-06-14T23:53:02 <+dekar> but there are thousands from different vendors
2012-06-14T23:53:11 <+dekar> all use different I2C implementations
2012-06-14T23:53:22 <+dekar> then there are firmware updates for transceivers
2012-06-14T23:54:27 <+dekar> and it is only transceivers, I have connected simple EEPROMS and the like though
2012-06-14T23:55:08 <+dekar> izua, some transceivers even use exotic stuff like I2C 10bit addresses
2012-06-14T23:55:29 <+izua> really?
2012-06-14T23:55:33 <+dekar> yeah
2012-06-14T23:55:36 <+izua> i never found a chip that does that :D
2012-06-14T23:55:45 <+dekar> we have quite a lot
2012-06-14T23:56:00 <+dekar> that usually do that as obfuscation
2012-06-14T23:56:04 <+izua> i2c is pretty bad imo, it leaves a lot of stuff undetailed, which leaves room for interpretation
2012-06-14T23:57:11 <+dekar> imo the problem rather is vendors implementing it badly on microcontrollers
2012-06-14T23:57:29 <+izua> that's a pretty fail obfuscation
2012-06-14T23:57:40 <+dekar> they often use parallel port bit bang programmers at low speed, so they never realize
2012-06-14T23:57:43 <+izua> what i'd do is something no one would expect, so they'd be thinking WTF
2012-06-14T23:58:00 <+izua> like, sending the first byte for a 10 bit address, then sending a repeated start
2012-06-14T23:58:13 <+izua> and have the chip work ONLY if it's addressed this way, heh
2012-06-14T23:58:53 <+dekar> izua, what do you mean? iirc if you only send the first byte it just is an i2c 7bit address
2012-06-14T23:59:04 <+dekar> oh you mean in the reserved address space for 10bit?
2012-06-14T23:59:14 <+izua> yeah, but it's a special address,, or an address space, to enter 10 bit mode
2012-06-14T23:59:30 <+izua> like, there are 4 addresses
2012-06-14T23:59:42 <+izua> yeah
2012-06-14T23:59:49 <+izua> i mean, no device COULD actually use that address
--- Day changed Fri Jun 15 2012
2012-06-15T00:00:04 <+izua> and have the second byte name clash with something really common, like an eeprom
2012-06-15T00:00:22 <+dekar> well many use 32bit passwords
2012-06-15T00:00:43 <+dekar> that's the most common way to protect transceivers
2012-06-15T00:00:47 <+izua> yeah
2012-06-15T00:00:50 <+izua> which you brute force :D
2012-06-15T00:00:57 <+dekar> :)
2012-06-15T00:01:00 <+izua> found any cool stuff through the passwords?
2012-06-15T00:01:14 <+dekar> nope, just some boring sequences and the like
2012-06-15T00:01:24 <+dekar> not even stuff like 0xBEEFSTEAKS
2012-06-15T00:01:27 <+izua> i think you can get stuff like DONT FUCK WITH USME
2012-06-15T00:01:29 <+dekar> uhm wait
2012-06-15T00:01:33 <+dekar> 0xDEADBEEF

2012-06-15T00:02:02 <+dekar> I'd prefer beefsteaks

2012-06-15T00:04:15 <+izua> i got a mill with italian spices
2012-06-15T00:04:21 <+dekar> O.o
2012-06-15T00:04:21 <+izua> like, the spices are inside the mini miller thingie
2012-06-15T00:04:47 <+izua> i was hoping to use the mill after the spices are gone, but it feels like it locks into place after being assembled :(

2012-06-15T00:07:40 <+dekar> izua, I think the pic is legit
2012-06-15T00:08:05 <+dekar> it's just a screenshot
2012-06-15T00:08:12 <+izua> that would be an incredibly small font he's using
2012-06-15T00:08:42 <+izua> but still, kudos for quadrupling the number of pixels and not using them for something useful, but just for shiny :D

2012-06-15T00:09:28 <+izua> yeah
2012-06-15T00:09:31 <+izua> exactly what i did
2012-06-15T00:09:33 <+izua> well
2012-06-15T00:09:49 <+izua> it's kind of pointless without having a 1080x2p display :P
2012-06-15T00:09:58 <+izua> actually
2012-06-15T00:10:03 <+izua> i'm going to rephrase my question
2012-06-15T00:10:12 <+izua> I don't see any difference between the two xD
2012-06-15T00:10:13 <+dekar> Qt apps supported retina stuff right away
2012-06-15T00:10:28 <+izua> neat.
2012-06-15T00:10:36 <+izua> isn't that controlled through the system wide dpi setting?
2012-06-15T00:10:40 <+izua> i know text is.
2012-06-15T00:10:40 < FUZxxl> Hello!
2012-06-15T00:10:50 < FUZxxl> I think I found a bug in either stlink or gdb.
2012-06-15T00:10:59 <+izua> i had a odd time getting used to thin borders of UI on a 1920x1080, 15 incher
2012-06-15T00:11:01 <+dekar> izua, is what controlled through the dpi settings?
2012-06-15T00:11:18 < FUZxxl> You can get a tarball of anything related at http://d00m.org/~fuz/gdb-crash.tar.bz2
2012-06-15T00:11:24 <+izua> "retina stuff", by which i assume you mean extra high quality graphics on the UI
2012-06-15T00:11:38 <+dekar> they have higher resolution icons and windows decorations
2012-06-15T00:11:44 <+izua> ah
2012-06-15T00:12:05 <+izua> but you need to add a bunch of includes, call some weird functions, read the callbacks, sacrifice the goat, and then recompile to get it working? :D
2012-06-15T00:12:19 <+dekar> for Qt you don't
2012-06-15T00:15:27 <+izua> does it come with its own sacrificial goat xD?
2012-06-15T00:15:43 <+izua> i've been taking a liking to qt lately
2012-06-15T00:15:51 <+izua> well, for the last year or so, since i started messing around with it
2012-06-15T00:16:48 <+izua> it's awesome for both crosscompiling and fast stuff (if you're like me and find python/mono/.net/java always being nothing more than prototyping languages)
2012-06-15T00:17:05 <+dekar> izua, I think they had to sacrifice the goat at nokia already when they added symbian support
2012-06-15T00:17:30 <+dekar> .net was always pretty fast for me
2012-06-15T00:17:42 <+dekar> java still is a bit sluggish
2012-06-15T00:18:06 <+dekar> well I only did C#.net
2012-06-15T00:18:18 <+izua> same
2012-06-15T00:18:34 <+izua> VB.net sounded like a fail
2012-06-15T00:20:12 < FUZxxl> Okay. Good night!
2012-06-15T00:20:50 <+izua> and thanks for all the fish

2012-06-15T03:00:52 < zippe> iR0b0t1: You were asking about DAC speeds?
2012-06-15T03:01:13 < zippe> iR0b0t1: There are two issues; for a SA ADC you need two extra clocks minumum for the SA to run
2012-06-15T03:02:21 < zippe> iR0b0t1: and for 12-bit vs 10-bit, you have to allow the S&H and the SA outputs to settle to 1/4 the margin
2012-06-15T03:03:07 < zippe> iR0b0t1: So for a given S&H / SA circuit, they will tend to settle within 1/2 LSB for a 10-bit converter about 4x as quickly as they will when the LSB is 1/4 the size.

2012-06-15T04:14:41 < karlp> also, it's probably an stlink bug, not a gdb bug :)
2012-06-15T04:16:58 < karlp> did adam dunkels write both lwip _and_ µip?
2012-06-15T04:17:07 < karlp> I thought those were two completely separate projects?
2012-06-15T04:17:43 < karlp> and... we're caught up again :)
2012-06-15T04:17:53 < karlp> zippe: yeah, I'd guess the black magic loader is gpl too.
2012-06-15T04:18:08 < karlp> binary blobs of gpl are weird and make my head hurt though
2012-06-15T04:20:48 < karlp> szczys: if the f0 has the same flash programming method as the f1, then you do not need a separate loader.
2012-06-15T04:21:21 < karlp> you may need separate registers for lock/unlock, but stlink already supports the f1, so copying an f1 loader from openocd isn't going to help you anyway

2012-06-15T08:27:03 < iR0b0t1> I was playing with brushless control for a while. That never really led anywhere for me... why not just buy a proper drive?
2012-06-15T08:33:22 < dongs> i made a brushless esc with failmega and stm32
2012-06-15T08:34:18 < iR0b0t1> Why two? Too processor intensive? That's what I usually found. The driver chips always seemed cheap enough to beat out making an ESC on a smaller chip

2012-06-15T10:37:20 < Tectu> here's a question: why do you use oil for cleaning= o0
2012-06-15T10:37:20 < dongs> cjbaird: why dont you just ufcking buy proper shit
2012-06-15T10:39:33 < cjbaird> It's more of a terpentine than oil. It's hella-good grime solvent, though-- I've got a mechanics hand-cleaner that uses limonine. I'm thinking though that I could use a limonine-based pre-wash stain remover to budge the ~30 years of crap off this 1980 Jefferson's BigboardII.

2012-06-15T11:19:53 < cjbaird> The plan will be to catalog & remove all the chips, clean the fuck out of the board (limonine, high-pressure water), test the electroylics and other caps, test the socket pins, go through the construction test guide, test the ICs individually, replace the missing EPROM.. A working original board will probably be worth a bit of money. A 6502 SYM1 I fixed up sold for $380.

2012-06-15T12:38:59 < ABLomas> (well, i do not like private queries too, especially when there's channel, where this question would be on-topic)
2012-06-15T12:39:07 < karlp> it's exactly how it was when I last touched it.
2012-06-15T12:39:14 < karlp> (ie, I'm not working on it right now)
2012-06-15T12:39:31 < karlp> but I'm using it in my day job all day right now, so that's nice
2012-06-15T12:39:38 < Tectu> karlp, how about doing some full erasement?

2012-06-15T16:02:14 < dongs> Operating system: GNU/Linux
2012-06-15T16:02:16 < dongs> that was its downfall
2012-06-15T16:03:22 <+Steffanx> Is that something you really want to remember?
2012-06-15T16:06:24 < dongs> it did cause a bit of internet trollery, so its noteworthy
2012-06-15T16:06:51 <+Steffanx> oh, ofcourse
2012-06-15T16:08:01 <+Steffanx> Did you go to Eduard Khil funaral btw?

2012-06-15T16:12:16 < dongs> The announcement included a tablet and Smartphone named the Grid 10 (10.1 inch tablet) and The Grid 4 (4 inch Smartphone), both running GridOS, a fork of the Android operating system.
2012-06-15T16:12:20 < dongs> haha gridos , more liek GRIDS
2012-06-15T16:17:07 < BrainDamage> sometimes I wonder if dongs is paid mby m$ to troll other OS
2012-06-15T16:17:18 < dongs> On January 9th 2012, Fusion Garage confirmed that the company had gone into liquidation owing creditors $40 million.

2012-06-15T16:52:57 < Laurenceb> im doing CE documentation

2012-06-15T16:54:17 <+dekar> [15:41]  <Tectu> btw, isnt     &buffer[0];   the same as  &buffer? <-- it isn't
2012-06-15T16:54:37 < Laurenceb> different type of pointer
2012-06-15T16:54:49 < Laurenceb> wait
2012-06-15T16:54:58 < Laurenceb> not &buffer is a pointer to a pointer
2012-06-15T16:55:02 <+dekar> &buffer[0]; is a pointer to the first element and &buffer; is a pointer to a pointer to the first element
2012-06-15T16:55:08 < Laurenceb> dawg
2012-06-15T16:55:31 < Tectu> ah, thanks :)
2012-06-15T16:55:34 < zyp> dekar, no
2012-06-15T16:56:12 <+dekar> zyp, yes :)
2012-06-15T16:56:17 < zyp> aren't buf and &buf equivalent when buf is an array?
2012-06-15T16:56:21 < Laurenceb> pointer to the array
2012-06-15T16:56:42 < karlp> no &buf[0] is euqal to buf when buf is an array
2012-06-15T16:56:51 < karlp> hmm, what does &buf oint to?
2012-06-15T16:56:55 < karlp> maybe that's also the same thing
2012-06-15T16:57:02 < pelrun_> &buf can't exist
2012-06-15T16:57:10 <+dekar> zyp, if buf is an array (a pointer) then &buf is a pointer to an array (pointer to a pointer)
2012-06-15T16:57:56 < zyp> arrays are not pointers
2012-06-15T16:58:12 < karlp> but the name of an array is defined to be a pointer to the first element isn't it?
2012-06-15T16:58:27 < karlp> which is why &buf[0] == buf
2012-06-15T16:58:27 <+dekar> zyp, they are
2012-06-15T16:58:42 < pelrun_> there is no &buf
2012-06-15T16:59:11 <+dekar> pelrun_, so how do you become three star programmer if pointers to pointers can't exist?
2012-06-15T16:59:24 < pelrun_> of course pointers to pointers can exist
2012-06-15T16:59:41 < pelrun_> you can't get a pointer to a pointer to an array
2012-06-15T16:59:55 < pelrun_> at least, not using that syntax
2012-06-15T17:00:02 <+dekar> sure you can, try it
2012-06-15T17:00:31 < pelrun_> so it implicitly creates a variable to hold the intermediate pointer?
2012-06-15T17:00:34 <+dekar> you'll need some brackets at some point, it will still work
2012-06-15T17:01:24 < pelrun_> "buf" is an array, not a variable holding a pointer to an array
2012-06-15T17:02:47 < zyp> pelrun_, exactly
2012-06-15T17:05:45 < pelrun_> c has syntactic sugar to get arrays to evaluate to their pointer in certain circumstances
2012-06-15T17:06:03 < Tectu> what?
2012-06-15T17:06:12 < Tectu> circumstances

2012-06-15T17:08:45 <+dekar> pelrun_, ofc they do, yet "&myArray" can exist
2012-06-15T17:08:58 <+dekar> I just prove it
2012-06-15T17:09:00 < pelrun_> it decays to just the array pointer
2012-06-15T17:10:05 < pelrun_> ah, heh
2012-06-15T17:10:45 <+dekar> pelrun_, want me to compile with -O0? it still runs
2012-06-15T17:10:50 < pelrun_> of course it runs
2012-06-15T17:10:53 <+dekar> that's valid C
2012-06-15T17:10:53 <+dekar> I don't get your point
2012-06-15T17:11:03 < pelrun_> it's just semantics
2012-06-15T17:11:03 < zyp> http://paste.jvnv.net/view/EXE8m <- I made a test here, it prints the same value three times.
2012-06-15T17:11:11 <+dekar> you can make pointers to pointers all day long
2012-06-15T17:11:14 < zyp> thus, all thre expressions are equivalent
2012-06-15T17:11:18 < zyp> three*
2012-06-15T17:11:44 < zyp> an array label can be implicitly casted to a pointer, but _is_ not a pointer
2012-06-15T17:11:50 <+dekar> "[15:58]  <pelrun_> there is no &buf"
2012-06-15T17:11:58 < zyp> because a pointer to an array is not the same as a pointer to a pointer
2012-06-15T17:12:26 < pelrun_> dekar: sorry, I was referring to the operation, not to how C actually decomposes the statement
2012-06-15T17:13:08 < zyp> pelrun_, huh?
2012-06-15T17:13:37 < pelrun_> lets just say my statement was imprecise
2012-06-15T17:14:16 < pelrun_> because C actually handles the statements identically, even though (decomposed)buf and &buf would seem to be different things
2012-06-15T17:15:24 <+dekar> zyp, I actually think they _are_ pointers, but stuff like "sizeof(myArray)" works with them (which doesn't work with pointers). Though that's due to the fact that the compiler evaluates sizeof at compile time in some cases
2012-06-15T17:15:37 < zyp> dekar, arrays are not pointers
2012-06-15T17:15:46 < pelrun_> dekar: read the c faq again - arrays are not pointers
2012-06-15T17:16:08 < zyp> dekar, I made a test with typeid() as well, it clearly distinguishes between arrays and pointers
2012-06-15T17:16:37 <+dekar> pelrun_, so what makes them different? the fact that GCC stores the size at myArray[-1]?
2012-06-15T17:16:46 < pelrun_> what?
2012-06-15T17:16:56 < zyp> dekar, you are clearly confused
2012-06-15T17:16:57 < pelrun_> no, it's a syntax thing
2012-06-15T17:17:15 < pelrun_> an array is the whole object of multiple memory locations
2012-06-15T17:17:17 <+dekar> I am pretty sure once they're compiled they're just pointers
2012-06-15T17:17:18 < zyp> dekar, size is _not_ stored at [-1]
2012-06-15T17:17:30 <+dekar> zyp, it is
2012-06-15T17:17:37 < pelrun_> a pointer is a single address
2012-06-15T17:17:38 < zyp> no.
2012-06-15T17:17:57 < pelrun_> I've never seen any reference to this array[-1] malarkey
2012-06-15T17:18:08 < zyp> pelrun_, because it's wrong
2012-06-15T17:18:24 < pelrun_> hence malarkey :)
2012-06-15T17:18:44 < zyp> dekar, are you thinking of heap allocations?
2012-06-15T17:19:05 < pelrun_> as soon as malloc comes into it, you don't have an array
2012-06-15T17:19:16 < zyp> pelrun_, exactly
2012-06-15T17:19:18 <+dekar> zyp, well maybe I am
2012-06-15T17:19:48 <+dekar> but what makes arrays different from pointers then? (once they're compiled)
2012-06-15T17:19:50 < pelrun_> you have a variable that holds a pointer to a region of memory
2012-06-15T17:20:04 < pelrun_> dekar: there are no arrays in compiled code
2012-06-15T17:20:15 <+dekar> so they just become pointers?
2012-06-15T17:20:16 < pelrun_> it's purely a C language construct
2012-06-15T17:20:41 <+dekar> well that's what I meant
2012-06-15T17:20:55 < zyp> dekar, the difference is that a pointer compiles to a symbol to a location containing an address, while an array compiles to a symbol to the data itself
2012-06-15T17:21:20 < zyp> dekar, so even from an assembly perspective, pointers and arrays are very different
2012-06-15T17:22:45 < pelrun_> dear god
2012-06-15T17:22:52 < pelrun_> 5["abcdef'} is legal C
2012-06-15T17:23:14 < pelrun_> uh, just pretend I typed a closing ] instead of a }
2012-06-15T17:23:33 < zyp> and " instead of '?
2012-06-15T17:23:51 < pelrun_> :S
2012-06-15T17:23:58 <+dekar> zyp, so how do they behave different if I call "printf("%u", myArray[-1]);"? I pass a pointer in both cases
2012-06-15T17:24:16 < zyp> dekar, what do you mean?
2012-06-15T17:24:38 <+dekar> you meant they are different even from an assembly perspective
2012-06-15T17:24:48 < zyp> ah, yes
2012-06-15T17:25:03 <+dekar> how would I see the difference?
2012-06-15T17:25:36 < zyp> let me make an example for you
2012-06-15T17:25:55 < zyp> do you prefer x86 or arm assembly?
2012-06-15T17:26:12 <+dekar> I barely know x86er
2012-06-15T17:26:19 <+dekar> so rather arm

2012-06-15T19:27:50 < TitanMKD> but support huge freq range and RX + TX :)
2012-06-15T19:28:27 < TitanMKD> Laurenceb your problem is USB does not work at all because of crystal ? or just the USB ?
2012-06-15T19:29:26 < Laurenceb> just the usb
2012-06-15T19:29:37 < Laurenceb> going to fix the xtal with the grovvy circuit form dongs
2012-06-15T19:29:54 < Laurenceb> i get how it works now, just an RC oscillator thats biased by the tcxo input
2012-06-15T19:30:09 < Laurenceb> so it could actually run at very small input voltages, very clever
2012-06-15T19:30:17 < TitanMKD> have you the right capacitor value for the external clock ?
2012-06-15T19:30:34 < Laurenceb> huh?
2012-06-15T19:30:37 < TitanMKD> anyway for USB it requires accurate oscillator and not a simple RC stuff
2012-06-15T19:30:39 < Laurenceb> i have a TCXO
2012-06-15T19:30:49 < Laurenceb> you dont understand
2012-06-15T19:30:53 < TitanMKD> ha yes tcxo oups
2012-06-15T19:31:03 < Laurenceb> you use an RC oscillator that give sabout the right freuqency
2012-06-15T19:31:14 < Laurenceb> then haxor it with a tcxo signal
2012-06-15T19:31:19 < TitanMKD> yes
2012-06-15T19:31:21 < Laurenceb> forcing it to phase with the tcxo
2012-06-15T19:31:29 < Laurenceb> its veyr clever
2012-06-15T19:31:44 < TitanMKD> we use a better stuff for that on JellyBean ;)
2012-06-15T19:32:04 < TitanMKD> a specific component to manage upto 8 different channel freq ;)
2012-06-15T19:32:24 < TitanMKD> the component is on lemondrop board in fact
2012-06-15T19:32:52 < TitanMKD> Si5351 is very good for that
2012-06-15T19:33:05 < TitanMKD> and the accuracy is just amazing
2012-06-15T19:33:09 < TitanMKD> 0 drift ...
2012-06-15T19:33:28 < TitanMKD> it is a VCXO
2012-06-15T19:34:01 < TitanMKD> freq can be programmed through I2C from 8KHz to 160MHz
2012-06-15T19:35:19 < TitanMKD> it also have an OTP to reload configuration at power on
2012-06-15T19:37:32 < Laurenceb> i dint knoe F4 has SSCG
2012-06-15T19:37:39 < Laurenceb> arg speeling
2012-06-15T19:50:38 < Laurenceb> i might be able to make it work with some resistors and a cap
2012-06-15T19:50:56 < Laurenceb> bbl

2012-06-15T22:14:01 < szczys> that third line is something I've never encountered before
2012-06-15T22:14:37 < karlp> you want -mthumb, but definitely not interwork.
2012-06-15T22:14:45 < karlp> drop all the float stuff too
2012-06-15T22:14:56 < karlp> and try -march=armv6-m
2012-06-15T22:15:00 < szczys> okay, thanks!
2012-06-15T22:15:26 < karlp> or armv6m-s or something, whatever zyp said earlier

2012-06-16T00:47:04 < szczys> All rejoice... I just comiled and loaded my first ARM program to flash... every!
2012-06-16T00:47:29 < szczys> Boy did I waste a lot of time getting one LED to illuminate :-)
2012-06-16T00:51:37 < zyp> did you get the flashloader working, or did you give up and use something else to flash?
2012-06-16T00:51:48 < szczys> I gave up and used OpenOCD
2012-06-16T00:52:30 < szczys> I don't know how to use a debugger, so I think it will be almost impossible for me to get that flash loader working in the stlink program
2012-06-16T00:53:38 < TitanMKD> To Flash & Debug for my STM32F4 Discovery I use EclipseIndigo+TrueSTUDIO for STMicroelectronics STM32 Lite 2.3.0 only the ST-LINK_gdbserver
2012-06-16T00:53:51 < szczys> right
2012-06-16T00:54:04 < TitanMKD> anyway also tested open source stlink and it work fine
2012-06-16T00:54:07 < szczys> I'm talking about debugging the stlink package as I try to get the flash programmer to work
2012-06-16T00:54:14 < szczys> right
2012-06-16T00:54:27 < szczys> but it currently can't write to flash on the STM32F0-Discovery
2012-06-16T00:54:58 < szczys> I believe zyp was the one who did the coding to get working with the F4
2012-06-16T00:55:26 < TitanMKD> woo there's support for STM32F05xx chips !!
2012-06-16T00:55:35 < TitanMKD> it is a typo or a new chipset ?
2012-06-16T00:55:50 < szczys> I added support to load into RAM
2012-06-16T00:55:56 < szczys> but it still lacks the ability to write to flash
2012-06-16T00:56:08 < szczys> I wish I could get it working... it's a lot easier than using OpenOcd
2012-06-16T00:56:29 < szczys> that's the chip on the STM32F0-Discovery board
2012-06-16T00:57:45 < zyp> szczys, I only added code to speed up flashing on F4
2012-06-16T00:57:56 < zyp> it was working before, I just made it faster
2012-06-16T00:58:30 < szczys> oh, I see
2012-06-16T00:58:50 < szczys> are you in contact with Texane often?
2012-06-16T00:59:53 < zyp> not at all
2012-06-16T01:00:18 < TitanMKD> anyone have info on STM32F5 features ?
2012-06-16T01:01:13 < karlp> someone said they'd been on some training recently,
2012-06-16T01:01:29 < karlp> but f3 and f5 were said to be f1/f4 sort of thing, with more analog front end
2012-06-16T01:01:29 < TitanMKD> i saw a powerpoint presentation
2012-06-16T01:01:34 < TitanMKD> it will be 55nm
2012-06-16T01:01:43 < karlp> what is f1/f4 now?
2012-06-16T01:01:49 < TitanMKD> 80nm
2012-06-16T01:02:03 < TitanMKD> so lot of space for lot of stuff ;)
2012-06-16T01:02:13 < TitanMKD> I want the SGPIO features like NXP LPC43xx
2012-06-16T01:02:16 < zyp> probably F2 rather than F1-ish
2012-06-16T01:02:30 < karlp> well, it's only interesting academcailly,
2012-06-16T01:02:34 < TitanMKD> and ADC @20msps ;)
2012-06-16T01:02:42 < karlp> I don't really need to care about 55nm vs 28nm vs 115nm,
2012-06-16T01:02:49 < zyp> TitanMKD, how does the SGPIO work?
2012-06-16T01:02:56 < karlp> just what the power consumption is for my own application for a given chip
2012-06-16T01:03:08 < TitanMKD> zyp you configure tons of stuff and at end it is like an FPGA
2012-06-16T01:03:09 < zyp> karlp, agreed, the results are what is interesting to us
2012-06-16T01:03:35 < zyp> TitanMKD, that's not a really good explanation :p
2012-06-16T01:03:43 < TitanMKD> zyp there's some slice stuff to link SGPIO between them like synchro on clock and also to serialize or deserialize with N SGPIO
2012-06-16T01:03:57 < zyp> I've heard about the SGPIO and what it can do, but not how and how it is used
2012-06-16T01:04:24 < TitanMKD> we have samples on hackrf
2012-06-16T01:04:37 < zyp> I assume you're not writing HDL for it, so it's not like an FPGA in that respect :p
2012-06-16T01:04:39 < karlp> that's not an explanation either :)
2012-06-16T01:04:43 < TitanMKD> it is more clear now but i need to experiment more to do a logic analyzer
2012-06-16T01:05:20 < TitanMKD> look here https://github.com/mossmann/hackrf/wiki/LPC4350-SGPIO-Experimentation
2012-06-16T01:05:52 < TitanMKD> it is not really easy to explain how it works it's totally new in fact
2012-06-16T01:06:29 < TitanMKD> but the best is you can do for example special SPI protocol running at up to 104MHz ;)
2012-06-16T01:06:47 < TitanMKD> or even a LCD driver fully managed by hardware

2012-06-16T01:22:55 < zyp> it's based around 16 shift registers, but have some flexible routing, data counters, configurable clock triggers, and data match
2012-06-16T01:30:27 < zyp> I've been meaning to play with LPC4300, but I haven't come across an interesting board yet

2012-06-16T01:51:38 < Laurenceb_> wtf, how are atmel so high up
2012-06-16T01:52:49 < Laurenceb_> i see an L4 and F5
2012-06-16T01:54:05 < zyp> Laurenceb_, because they have their feet in several camps? they do both AVR, AVR32 and ARM stuff
2012-06-16T01:54:25 < karlp> they are populare in automotive too iirc
2012-06-16T01:54:50 < karlp> find the same pdf from atmel's company briefing :)
2012-06-16T02:01:08 < karlp> has anyone done anything along the lines of the eeprom emulation in flash app note?
2012-06-16T02:01:31 < karlp> how do you get a linker script to declare & then avoid placing anythign else in that section?
2012-06-16T02:01:45 < karlp> and do you have just to be careful when reprogramming not to overwrite that section?
2012-06-16T02:01:58 < karlp> or is it something you're expected to reinitialise if you reprogramm?
2012-06-16T02:03:31 < zyp> I haven't read the app note closely, but it's just using a flash page as eeprom, right?
2012-06-16T02:04:32 < zyp> reserving room for it in the linker script is easy, if you choose the last page on the flash you just reduce the flash size listed in the linker script

2012-06-16T02:06:27 < Laurenceb_> you need to do erase first tho?
2012-06-16T02:06:35 < Laurenceb_> so its not like using eeprom on avr
2012-06-16T02:06:49 < zyp> so you either have to be careful or reinitialise it, depending on what suits you best
2012-06-16T02:06:59 < zyp> Laurenceb_, yes
2012-06-16T02:07:09 < karlp> no, then it would be eeprom :)
2012-06-16T02:07:12 < karlp> like on the L1,
2012-06-16T02:07:29 < zyp> flash memory is pretty much eeprom with page granularity erase
2012-06-16T02:07:42 < Laurenceb_> and less endurance
2012-06-16T02:08:01 < zyp> and less cost

2012-06-16T13:54:56 < Tectu> morning
2012-06-16T13:55:50 < Tectu> question:    buffer is of type  uint8_t*    and  s  is of type  uint16_t        what's the value of s here?    s=*((uint16_t*)&buffer[0]);
2012-06-16T13:56:04 < Tectu> is it the integer value of the first element in the array
2012-06-16T14:01:44 < zyp> are you still going on about that?
2012-06-16T14:03:10 < Tectu> zyp, yeah, just came across it again -.-
2012-06-16T14:03:19 < zyp> anyway, it's «s = an 16-bit unsigned read from 0 bytes into the buffer»
2012-06-16T14:03:57 < zyp> &buffer[0] doesn't make sense by itself, but it would kind of make sense if it were &buffer[5] or something
2012-06-16T14:04:29 < zyp> because it will then skip the first five bytes, then read the next two and interpret those as an uint16_t
2012-06-16T14:04:46 < zyp> so it's likely to keep a consistent coding style
2012-06-16T14:05:11 < zyp> though, &buffer[x] equals (buffer + x)
2012-06-16T14:06:27 < Tectu> so if buffer[0] = 4 and buffer[3] = 2;    and i do    &buffer[3], i get 6?
2012-06-16T14:06:56 < zyp> wtf, no.
2012-06-16T14:07:20 < Tectu> it would be something arround 500, right?
2012-06-16T14:07:38 < zyp> buffer[3] would be 2, so &buffer[3] would be the address where the value 2 is stored
2012-06-16T14:07:46 < Tectu> o0
2012-06-16T14:07:51 < Tectu> i mean the whole line
2012-06-16T14:07:57 < Tectu> s=*((uint16_t*)&buffer[0]);
2012-06-16T14:08:11 < Tectu> this makes no sense -.-
2012-06-16T14:08:18 < zyp> you make no sense
2012-06-16T14:08:35 < zyp> remember that you are talking about 16-bit ints
2012-06-16T14:09:26 < zyp> if buffer[0] = 4 and buffer[1] = 2, that line would give you s = 516 on a little-endian system
2012-06-16T14:09:34 < Tectu> yeah
2012-06-16T14:09:38 < Tectu> <Tectu> it would be something arround 500, right?
2012-06-16T14:09:45 < zyp> and s = 1026 on a big-endian system
2012-06-16T14:09:54 < zyp> note that I wrote buffer[1] and not buffer[3]
2012-06-16T14:10:10 < Tectu> <zyp> though, &buffer[x] equals (buffer + x)
2012-06-16T14:10:23 < zyp> yes
2012-06-16T14:10:24 < Tectu> buffer + x   <---    buffer[0] buffer[x]   ?
2012-06-16T14:10:32 < zyp> no.
2012-06-16T14:10:42 < zyp> buffer is the address of the array
2012-06-16T14:10:54 < Tectu> and x the element offset
2012-06-16T14:10:59 < zyp> yes
2012-06-16T14:11:33 < zyp> and &buffer[x] gives you address of element, while (buffer + x) adds offset to base address of array, which all makes out to the same
2012-06-16T14:12:35 < zyp> remember that &buffer[x] is read as &(buffer[x])
2012-06-16T14:12:46 < Tectu> aaah!
2012-06-16T14:12:49 < Tectu> now i see it
2012-06-16T14:22:53 < cjbaird> Programming fun: stuffing shorts/ints into character arrays with crap like: ps = (short*)&buffer[pc]; *ps = (short)255; ..compiling into 1-2 instructions, instead of ~12 ... Also funky speed improvements like:  http://dpaste.org/4OYvM/
2012-06-16T14:24:15 < zyp> huh?
2012-06-16T14:25:23 < Tectu> what?
2012-06-16T14:25:35 <+Steffanx>  /what/wat
2012-06-16T14:26:48 < cjbaird> The first bit replaces "buffer[pc] = 0; buffer[pc+1]= 255;" which arm-none-eabi-gcc would convert into ~12 instructions, into a load.w op. The paste zeros the area in 16384 loops instead of 65536..

2012-06-16T15:16:22 < cjbaird> Something weak about the current state of the GCC ARM backend I've noticed is that you can reduce the number of instructions used by reordering code in stuff like "carry=0,zero=reg==0,sign=0;" .. in spite of the C spec allowing the compiler to do anything it likes in that situation for the sake of the preferred optimisation level, gcc/arm just does it dumb, and you get better results by rewriting it as "zero=reg==0,carry=0,sign=0;

2012-06-16T15:53:51 < dongs> no
2012-06-16T15:53:58 < dongs> it means he could have been in tokyo at some point
2012-06-16T15:54:00 < Tectu> dongs, he clearly said to me that he's going to tokyo
2012-06-16T15:54:01 < dongs> and saw the signs
2012-06-16T15:54:09 < Tectu> the last few days
2012-06-16T15:54:12 < Tectu> and i think he still is

2012-06-16T15:54:59 < dongs> this gives me function signatures and asm to compare
2012-06-16T15:55:07 < dongs> makes shit a lot easier to track down
2012-06-16T15:55:25 < dongs> so as i suspected these morons are using double versions of all math shit

2012-06-16T18:49:13 <+izua> because being exclusive to one OS is fail, when you need to use something that only the other OS has
2012-06-16T19:07:05 <+izua> dunno. i was curious
2012-06-16T19:07:22 <+izua> a  VL discovery is prettyepic, compared to say, an arduino
2012-06-16T19:07:28 <+izua> and it costs, what, 33%?
2012-06-16T19:07:47 <+izua> you could make a programmer/mini logic analyzer/butt pirate out of it
2012-06-16T19:08:25 <+izua> plus, because you don't need to remap stuff
2012-06-16T19:08:36 <+izua> you can do stuff like "dump usart2 to spi3"
2012-06-16T19:09:56 < BrainDamage> even a f4 costs less than an arduino
2012-06-16T19:10:02 < BrainDamage> f4 discovery
2012-06-16T19:10:13 < BrainDamage> I paid the discovery 16€, an arduino costs > 20
2012-06-16T19:10:21 <+izua> hehe
2012-06-16T19:10:23 <+izua> 168MHz
2012-06-16T19:10:47 <+izua> they're not free
2012-06-16T19:11:15 <+izua> st is probably going in the red with the discovery line, though
2012-06-16T19:12:09 <+izua> i was thinking more like total cost
2012-06-16T19:12:40 <+izua> the two chips on a VL discovery, crystal, connectors, buttons, and leds, not counting pcb manufacturing and part assembly, easily cost > €10

2012-06-16T20:18:25 < dongs> flyback: that M3 costs them < $2
2012-06-16T20:18:32 < dongs> F0 is ~$1
2012-06-16T20:18:43 < dongs> the rest of the bom is probably < $3
2012-06-16T20:18:52 < dongs> pcbs in the qty they're making them are cheap
2012-06-16T20:35:15 <+izua> dongs: was that to me?
2012-06-16T20:36:03 < dongs> 01:12 <+izua> the two chips on a VL discovery, crystal, connectors, buttons, and leds, not counting pcb manufacturing and part assembly, easily cost > EUR10
2012-06-16T20:36:07 < dongs> ya
2012-06-16T20:36:28 <+izua> really?
2012-06-16T20:36:28 < dongs> believe it or not, they might be breaking even or even making something on them
2012-06-16T20:36:32 < dongs> well, when they sell them that is
2012-06-16T20:36:35 < dongs> not when they give htem away.
2012-06-16T20:36:35 < dongs> yes
2012-06-16T20:36:40 <+izua> i always thought that's the reason for the "don't use it in something else" agreement
2012-06-16T20:36:41 < dongs> even I can get C8T6 for $2
2012-06-16T20:36:45 < dongs> and im sure ST pays a lot less
2012-06-16T20:37:30 < dongs> F4-discovery im not so sure, but its also not too terribly complex
2012-06-16T20:38:47 < karlp> izua:  I think it's because they're not making enough on the discovery boards,
2012-06-16T20:39:00 < karlp> and they know that they're cheap enough to tempt people to just use them in finished products
2012-06-16T20:39:04 < karlp> and they want more margin
2012-06-16T20:39:04 < dongs> dont use it in something else what
2012-06-16T20:39:06 < dongs> oh please
2012-06-16T20:39:11 < dongs> karlp: dont be ridiculous
2012-06-16T20:39:13 < karlp> my money's on them breaking about even.
2012-06-16T20:39:16 < dongs> nobody would use that shit ina  finished product
2012-06-16T20:39:19 < karlp> sure theyw ould
2012-06-16T20:39:21 < dongs> no.
2012-06-16T20:39:28 < dongs> only some tarduino retards would even THINK something like that
2012-06-16T20:39:32 < karlp> yep :)
2012-06-16T20:39:34 < karlp> but you know what,
2012-06-16T20:39:38 < karlp> if it's in a box,
2012-06-16T20:39:43 < karlp> and you got it done quick
2012-06-16T20:39:47 < karlp> it's ok for 10 sales or so
2012-06-16T20:39:53 < dongs> ya but no way
2012-06-16T20:40:01 < karlp> we _sold_ an arduino + ether+ third board stacked on top
2012-06-16T20:40:06 < karlp> it was _stupid_
2012-06-16T20:40:08 < karlp> but we sold it
2012-06-16T20:40:47 < Steffann> LOL
2012-06-16T20:41:04 <+izua> it's not something fair
2012-06-16T20:41:12 <+izua> but if you need a quick turnaround, it's better than an arduino
2012-06-16T20:41:14 < karlp> (we don't sell it any mor eby the way, that product was already built when I started at work)
2012-06-16T20:41:58 <+izua> maybe the whole no resell agreement is just reverse pscyhology so clients can buy more
2012-06-16T20:51:27 < dongs> ugh this hotel is retarded
2012-06-16T20:51:30 < dongs> no free toothpaste
2012-06-16T20:51:43 < dongs> and the brush thats free says "bring unusede brush to front desk to receive a small gift"

2012-06-16T20:54:16 < Steffann> only in japan
2012-06-16T20:55:16 < Laurenceb_> my friend is renting out his house to a Buddhist
2012-06-16T20:55:42 < Laurenceb_> she never paid any rent, and he was asking her to pay up
2012-06-16T20:56:07 < Laurenceb_> he got a letter through the door from her, and opened it up expecting to find money.
2012-06-16T20:56:47 < Laurenceb_> there was a root from some dead weeds inside with a note saying "please take this and eat it as a token of my appreciation"
2012-06-16T20:57:13 <+izua> wsrofl
2012-06-16T20:57:14 <+izua> win
2012-06-16T20:57:37 <+izua> why would buddhists want a house though?
2012-06-16T20:57:46 < Laurenceb_> she has load sof children
2012-06-16T20:58:35 < Steffann> Good troll :)
2012-06-16T20:58:41 < Laurenceb_> she was serious
2012-06-16T20:59:09 < Laurenceb_> he went round to the house and she lectured him for being too greedy and not appreciating the gifts of nature
2012-06-16T21:00:22 < BrainDamage> we'll see how the court will appreciate it I guess
2012-06-16T21:00:23 <+izua> yeah, what Steffann said ><
2012-06-16T21:00:30 <+izua> i don't think she'd really care
2012-06-16T21:00:32 < BrainDamage> my father had insolvent people too
2012-06-16T21:00:34 <+izua> she'll get free food and housing
2012-06-16T21:00:44 <+izua> as opposed to roots and rent
2012-06-16T21:01:09 < Steffann> Yeah, but you are from italy BrainDamage
2012-06-16T21:01:10 < BrainDamage> she's not paying rent, so how's different from free housing?
2012-06-16T21:01:13 < Steffann> That explains a lot :P
2012-06-16T21:01:32 < BrainDamage> actually yes, the law here is particularry bad wrt rentint and insolvents
2012-06-16T21:01:33 <+izua> she did haveto sweettalk her way into getting the place, and delaying payments
2012-06-16T21:01:40 < BrainDamage> it's always to the insolvent's part :/
2012-06-16T21:01:51 < BrainDamage> they had to wait > 12 months to get rid of him

2012-06-17T01:30:00 < Rickta59> hey szczys .. i am
2012-06-17T01:30:06 < Rickta59> i didn't make any headway the other day
2012-06-17T01:30:07 < szczys> I've been busy
2012-06-17T01:30:18 < szczys> check out the template I built for compiling and programming flash:
2012-06-17T01:30:24 < szczys> https://github.com/szczys/stm32f0-discovery-basic-template
2012-06-17T01:30:31 < Rickta59> and I kind of bailed and have been figuring out how to use the openocd
2012-06-17T01:30:47 < Rickta59> nice
2012-06-17T01:30:50 < szczys> I built command line programming with OpenOCD into the makefile of that template
2012-06-17T01:31:07 < szczys> just type "make program" and it will upload the .bin file automatically
2012-06-17T01:31:20 < Rickta59> do you have issues when you connect to opencd with gdb?
2012-06-17T01:31:22 < szczys> (assuming you have openocd installed correctly)
2012-06-17T01:31:41 < szczys> yes
2012-06-17T01:31:44 < szczys> not all the time
2012-06-17T01:31:57 < szczys> but I had been using Telnet instead of GDB because of it
2012-06-17T01:32:10 < Rickta59> http://michaldemin.wordpress.com/2010/02/22/part-2-debugging-with-gdb-and-openocd/
2012-06-17T01:32:12 < szczys> I think it might have something to do with GDB not erasing the flash
2012-06-17T01:32:46 < Rickta59> i think someone here mentioned it the other day, in that gdb and openocd have a disagreement when it comes to registers
2012-06-17T01:32:59 < Rickta59> openocd -f openocd.cfg -c "init" -c "halt" -c "reset halt"
2012-06-17T01:33:06 < Rickta59> that seemed to help
2012-06-17T01:33:43 < Rickta59> of course with the right -f config for the f0 board
2012-06-17T01:34:09 < Rickta59> i saw your question earlier about plug unplug
2012-06-17T01:34:11 < Rickta59> i think
2012-06-17T01:34:12 < szczys> yeah... check out the extra folder in that repo I linked
2012-06-17T01:34:22 < Rickta59> monitor reset run might work
2012-06-17T01:34:32 < szczys> really?
2012-06-17T01:34:38 < Rickta59> from in gdb yes
2012-06-17T01:34:45 < szczys> doubtful
2012-06-17T01:35:37 < szczys> playing with it right now
2012-06-17T01:36:58 < Tectu> damn, can someone help me here? Am I stupid or just to tired?    http://codepad.org/N6f3jUcB
2012-06-17T01:38:23 < Rickta59> hmm .. nm i'm trying too many things at once
2012-06-17T01:38:55 < Rickta59> i was using the summon build of arm-none... .. and that gdb isn't happy with openocd
2012-06-17T01:39:10 < Rickta59> i downloaded an older version of the codesourcery lite and that connects
2012-06-17T01:39:12 < Tectu> Rickta59, what exactly does summon have to do with gdb?
2012-06-17T01:39:15 < szczys> how to I load an elf file using GDB?
2012-06-17T01:39:27 < Tectu> szczys,      (gdb)  load file.elf
2012-06-17T01:39:27 < Rickta59> it builds gdb
2012-06-17T01:39:46 < Tectu> szczys, for better debugging, start gdb with the .elf as first argument
2012-06-17T01:39:49 < szczys> hey
2012-06-17T01:39:50 < Tectu> like
2012-06-17T01:39:55 < szczys> right, I did that
2012-06-17T01:39:58 < Tectu> $ arm-none-eabi-gdb foo.elf
2012-06-17T01:39:59 < szczys> just didn't try typing load
2012-06-17T01:40:02 < Tectu> then just type load
2012-06-17T01:40:09 < Tectu> works here every time
2012-06-17T01:40:16 < szczys> but I think using "monitor reset run" after load works

2012-06-17T01:41:17 < szczys> I had been trying to get Flash write working in texane's stlink package
2012-06-17T01:41:20 < szczys> but hit a wall with it
2012-06-17T01:41:24 < Tectu> Rickta59, at least that's the right way ;)
2012-06-17T01:41:43 < Rickta59> i really waiting for szczys to fix it ; )
2012-06-17T01:41:43 < Tectu> szczys, does work for me and everbody else...  where was your problem?
2012-06-17T01:41:47 < Tectu> and what do you use now, szczys
2012-06-17T01:41:53 < Rickta59> f0 board isn't supported Tectu
2012-06-17T01:41:58 < Tectu> ah :D
2012-06-17T01:42:04 < Tectu> when did you try last time?
2012-06-17T01:42:11 < Tectu> they did some F0 related commits a few days ago
2012-06-17T01:42:16 < Rickta59> he did it
2012-06-17T01:42:18 < Tectu> not sure if it is yet working
2012-06-17T01:42:33 < Rickta59> but didn't fix the flash loading part .. just loading to ram
2012-06-17T01:42:47 < Tectu> then fix it yourself is always a good step :D
2012-06-17T01:42:47 < szczys> yeah... which is something I guess
2012-06-17T01:43:07 < szczys> but without the ability to write to flash it's not of very much use
2012-06-17T01:43:28 < Rickta59> so with openocd the other day szczys .. how did you load that bin file?
2012-06-17T01:43:34 < Laurenceb_> http://www.st.com/internet/mcu/product/251211.jsp?WT.ac=spear_spear1340_apr11
2012-06-17T01:43:38 < Laurenceb_> ^interesting
2012-06-17T01:44:30 < Tectu> Laurenceb_, got one?
2012-06-17T01:44:50 < szczys> Rickta59: Ya!
2012-06-17T01:44:58 < szczys> you're right... I'm using "reset run"
2012-06-17T01:45:07 < Laurenceb_> preview :(
2012-06-17T01:45:09 < szczys> and now I don't need to power cycle
2012-06-17T01:45:19 < szczys> pushing to github once I get the README updated
2012-06-17T01:45:22 < Rickta59> did it pick up your latest changes
2012-06-17T01:45:33 < Rickta59> on the firmware i mean
2012-06-17T01:45:45 < szczys> yes
2012-06-17T01:45:50 < Tectu> Laurenceb_, shut up and take my money!
2012-06-17T01:45:50 < szczys> I did a mass erase separately
2012-06-17T01:45:52 < szczys> then power cycled
2012-06-17T01:46:06 < szczys> then used "make program" with my updated command (reset run)
2012-06-17T01:46:07 < Rickta59> so to load a bin? you did that with a command ?
2012-06-17T01:46:16 < szczys> and it started blinking as soon as the write process finished
2012-06-17T01:46:17 < szczys> yay!
2012-06-17T01:46:27 < Rickta59> i want to make sure i can get back to the original firmware
2012-06-17T01:47:11 < Tectu> Rickta59, firmware?
2012-06-17T01:47:16 < Tectu> which firmware and where firmware?
2012-06-17T01:47:30 < Rickta59> as opposed to github
2012-06-17T01:47:48 < Rickta59> firmware .. the other day i snapped the flash and saved it to a bin file
2012-06-17T01:48:07 < szczys> Rickta59: here's the commands I use from telnet:
2012-06-17T01:48:15 < szczys> telnet localhost 4444
2012-06-17T01:48:17 < szczys> reset halt
2012-06-17T01:48:18 < Rickta59> and szczys was able to reload that on his f0 board after he found out that he couldn't load with stlink
2012-06-17T01:48:27 < szczys> stm32f1x mass_erase 0
2012-06-17T01:48:40 < Rickta59> f1x on the f0 board?
2012-06-17T01:48:46 < szczys> flash write_image /path/to/orig.bin 0x08000000
2012-06-17T01:48:57 < Rickta59> great thanks
2012-06-17T01:49:00 < szczys> verify_image /path/to/orig.bin 0x08000000
2012-06-17T01:49:04 < szczys> reset run
2012-06-17T01:49:05 < szczys> shutdown
2012-06-17T01:49:15 < szczys> Rickta59: is that what you were after?

2012-06-17T01:49:53 < szczys> most of that can be done through gdb too
2012-06-17T01:49:58 < szczys> but I know for sure that works every time
2012-06-17T01:50:02 < Rickta59> I haven't spent any time reading the docs on openocd .. didn't want to invest too much time if stlink was going to start working
2012-06-17T01:50:04 < szczys> just try verifying the image first
2012-06-17T01:50:12 < szczys> then you can erase it and rewrite it
2012-06-17T01:51:00 < Rickta59> what version of arm gdb do you have?
2012-06-17T01:51:29 < Tectu> szczys, texane does work too, it just segfaults every 5 writes
2012-06-17T01:52:06 < szczys> tectu, really?
2012-06-17T01:52:17 < szczys> what commands are you using to get it to work?
2012-06-17T01:52:25 < Tectu> szczys, what exactly do you mean?
2012-06-17T01:52:30 < Tectu> it   load; run;
2012-06-17T01:52:34 < Tectu> nothing more :)
2012-06-17T01:52:37 < Tectu> then ctrl+c
2012-06-17T01:52:38 < Rickta59> to flash?
2012-06-17T01:52:39 < Tectu> do debugg
2012-06-17T01:52:41 < Rickta59> or ram
2012-06-17T01:52:44 < szczys> oh
2012-06-17T01:52:45 < Tectu> just  type   'load'
2012-06-17T01:52:51 < Tectu> or   even  'lo'   is enought
2012-06-17T01:52:54 < Tectu> and   'r'  for run
2012-06-17T01:53:02 < szczys> for a flash program?
2012-06-17T01:53:05 < szczys> or a ram program?
2012-06-17T01:53:10 < Rickta59> you have an f0 board Tectu?
2012-06-17T01:53:22 < Tectu> Rickta59, no i don't
2012-06-17T01:53:29 < Rickta59> then how can you say it works?
2012-06-17T01:53:34 < Tectu> Rickta59, i talk about texane in general?!
2012-06-17T01:53:37 < szczys> this is specifically an f0 problem we're talking about
2012-06-17T01:53:40 < Tectu> ah
2012-06-17T01:53:42 < Tectu> sorry then
2012-06-17T01:53:45 < szczys> no problem
2012-06-17T01:53:49 < szczys> we figured it out ;-)
2012-06-17T01:54:36 < Rickta59> so if checkout this template thing it will create the CMSIS stuff for me?
2012-06-17T01:55:34 < szczys> Yes..
2012-06-17T01:55:38 < szczys> if you look in the Libraries directory
2012-06-17T01:55:53 < szczys> it's all the files from the STM32f0xx Standard Peripheral Library
2012-06-17T01:55:56 < Rickta59> make install?
2012-06-17T01:56:00 < Rickta59> : )
2012-06-17T01:56:11 < szczys> (I read the license and believe this is allowed)
2012-06-17T01:56:20 < szczys> just type make
2012-06-17T01:56:23 < szczys> to compile the file
2012-06-17T01:56:27 < szczys> and look for errors
2012-06-17T01:56:35 < szczys> if it created a main.bin (and main.elf)
2012-06-17T01:56:42 < szczys> you can type make program to flash it to your board
2012-06-17T01:56:44 < Rickta59> k that worked
2012-06-17T01:57:05 < Rickta59> hmm .. program .. not so much
2012-06-17T01:57:13 < Rickta59> i didn't install in that default directory
2012-06-17T01:57:23 < szczys> edit Makefile
2012-06-17T01:57:34 < szczys> change the OPENOCD_BOARD_DIR variable
2012-06-17T01:58:13 < szczys> to reflect the proper directory (containing stm32f0discovery.cfg)

2012-06-17T02:03:28 < Rickta59> nice work .. thanks
2012-06-17T02:03:37 < szczys> it's just blinking one and off at 1 Hz, right?
2012-06-17T02:03:57 < Rickta59> yep
2012-06-17T02:04:04 < szczys> that's how I programmed it

2012-06-17T02:05:59 < Rickta59> i was just verifying that you also had an old version

2012-06-17T04:33:07 < zippe> I would be more worried about it disintegrating in midair
2012-06-17T04:33:13 < szczys> hmmm... any idea where i can read about the SysTick registers?
2012-06-17T04:33:16 < szczys> Not in the reference manual
2012-06-17T04:33:25 < szczys> and I see their mapped to the CMSIS header files
2012-06-17T04:33:27 < dongs> why do you need to read about systick registers
2012-06-17T04:33:32 < zippe> szczys: systick is documented in the architecture reference

2012-06-17T04:34:22 < szczys> I think it might be an issue with how SysTick is defined
2012-06-17T04:34:28 < szczys> so I'm sleuthing
2012-06-17T04:34:30 < dongs> so, you probaly built it for HSE while there isnt one on the boarD?

2012-06-17T04:34:43 < szczys> maybe
2012-06-17T04:34:51 < szczys> is that configured in the example code
2012-06-17T04:34:56 < szczys> or in my Makefile?
2012-06-17T04:35:27 < dongs> im not sure, There should be a system_xxx.c or so to bring up pll/clocks
2012-06-17T04:35:31 < dongs> in each sample project
2012-06-17T04:35:40 < zippe> szczys: that sounds a lot like you're still running off the osc direct
2012-06-17T04:35:52 < szczys> yeah, it's blinking
2012-06-17T04:36:01 < szczys> I figure if it were configured for a clock that wasn't there nothing would happen
2012-06-17T04:36:02 < szczys> right?
2012-06-17T04:36:29 < szczys> There isn't really a way to compare the two .bin files, is there?
2012-06-17T04:36:33 < zippe> i.e. you probably haven't called the routine that sets up the PLL
2012-06-17T04:36:37 < szczys> I have no idea what was used to compile the original
2012-06-17T04:36:48 < zippe> dongs: the FY20 is somewhat annoying; it has a different pinmap
2012-06-17T04:36:54 < szczys> I'm not calling anything... I'm just compiling the example files
2012-06-17T04:37:59 < szczys>   RCC_GetClocksFreq(&RCC_Clocks);
2012-06-17T04:37:59 < szczys>   SysTick_Config(RCC_Clocks.HCLK_Frequency / 1000);
2012-06-17T04:38:15 < szczys> oh, and this higher up:
2012-06-17T04:38:16 < szczys> RCC_ClocksTypeDef RCC_Clocks;
2012-06-17T04:38:32 < zippe> GetClocksFreq only works if you have called the other half, which is normally done at startup
2012-06-17T04:38:55 < szczys> what 'other half' should i be looking for?
2012-06-17T04:39:45 < zippe> There's a system init function that should be called early, it *should* be pretty obviou
2012-06-17T04:39:58 < szczys> in main.c or elsewhere?
2012-06-17T04:40:48 < zippe> yes
2012-06-17T04:41:02 < dongs> zippe: i trhought that was solved
2012-06-17T04:41:04 < dongs> whats differnt?
2012-06-17T04:41:42 < zippe> The FY90A pinout looks like T2/1-4 and T3/1-4 are pinned out
2012-06-17T04:42:13 < dongs> oh nice
2012-06-17T04:42:17 < dongs> so they fixed EXTI shit?
2012-06-17T04:42:54 < zippe> But the FY20 brings out T2/1,2,4, then T41,2,4
2012-06-17T04:43:30 < zippe> Oh god wait no no no
2012-06-17T04:43:36 < zippe> why am I looking at the F100 datasheet?
2012-06-17T04:43:43 < dongs> haha
2012-06-17T04:44:29 < zippe> Probably similar, but still
2012-06-17T04:46:31 < szczys> zippie: Looks like there's SystemInit() functin that is called by the startup file
2012-06-17T04:46:44 < zippe> Ok, so that's supposed to cut you over to the PLL
2012-06-17T04:47:13 < zippe> dongs: yeah, so for some inexplicable reason the "AIL in" is routed to PA4, which doesn't connect to a timer at all
2012-06-17T04:48:10 < zippe> Basically means some extra hacks required to the FY90 PWM driver
2012-06-17T04:48:29 < dongs> yeah
2012-06-17T04:48:37 < dongs> you'd have to use EXTI and shit.
2012-06-17T04:48:45 < dongs> I just ended up making it use PPM sum input
2012-06-17T04:49:08 < zippe> Yeah, that's what I was going to do
2012-06-17T04:49:17 < zippe> But I can't even run four motors off a single timer
2012-06-17T04:53:18 < szczys> why is it when I use x/x <address> to read registers I only get 16-bits back
2012-06-17T04:53:24 < szczys> aren't these 32-bit registers?
2012-06-17T04:53:35 < dongs> are you reading sustick shit?
2012-06-17T04:53:37 < dongs> they're 16bit.
2012-06-17T04:53:50 < zippe> When you say "only get 16-bits back", what do you mean?
2012-06-17T04:55:52 < szczys> zo
2012-06-17T04:56:05 < szczys> ah
2012-06-17T04:56:13 < szczys> I'm confusing hex and bin
2012-06-17T04:56:13 < szczys> sorry
2012-06-17T05:00:19 < szczys> comparing hex values read from a 32-bit register to binary values in the register description of the datasheet is amazingly difficult
2012-06-17T05:01:39 < BrainDamage> szczys: are you on linux? if so install qalculate-gtk
2012-06-17T05:01:55 < BrainDamage> then copypaste the hex like 0xhexcode
2012-06-17T05:02:03 < BrainDamage> and convert the result to binary
2012-06-17T05:03:34 < zippe> er, or you can use x/b
2012-06-17T05:04:23 < szczys> BrainDamage: Thanks for the tip, that will come in handy
2012-06-17T05:04:52 < szczys> zippie: that doesn't seem to work
2012-06-17T05:04:57 < BrainDamage> it's an awesome calculator regardless, even handles physical units
2012-06-17T05:05:41 < szczys> zippie it just trunkates it down to two digits
2012-06-17T05:05:44 < szczys> still in hex
2012-06-17T05:08:35 < szczys> zippe: I'm digging in the gdb documentation and found it: x/wt <address>
2012-06-17T05:08:37 < szczys> thanks!
2012-06-17T05:08:57 < zippe> Ah, ok, must have changed at some point
2012-06-17T05:09:00 < zippe> I never use it...
2012-06-17T05:09:03 < szczys> although that output should have a space every four bits
2012-06-17T05:09:05 < Rickta59> are you using system_stm32f0xx.c from teh Project/Demostration?
2012-06-17T05:09:07 < szczys> hard to figure out what's in the middle
2012-06-17T05:09:16 < szczys> Rickta59: yes
2012-06-17T05:09:18 < Rickta59> that seems to default to the right clock
2012-06-17T05:09:35 < szczys> that's why I think the systick value might be the culprit
2012-06-17T05:09:50 < Rickta59> PLL_SOURCE_HSI is the default
2012-06-17T05:10:00 < Rickta59> so life should be good
2012-06-17T05:10:07 < szczys> I'd like to read the registers from the .bin that ships, and compare it to what I've compiled
2012-06-17T05:10:15 < szczys> It blinks too slow
2012-06-17T05:10:28 < szczys> I'd estimate it's blinking half as fast
2012-06-17T05:10:39 < szczys> as what shipped with the board
2012-06-17T05:10:51 < szczys> and the button press reaction is like half as fast
2012-06-17T05:10:53 < Rickta59> have you tried cycling through
2012-06-17T05:11:04 < szczys> which makes me think the delay function is slower
2012-06-17T05:11:12 < szczys> which is governed by the systick interrupt
2012-06-17T05:11:25 < szczys> so either the systick is setup differently
2012-06-17T05:11:34 < szczys> or the clock it's based on is running slow
2012-06-17T05:11:34 < Rickta59> are you compiling with optimization?
2012-06-17T05:11:41 < szczys> hmmmmmm
2012-06-17T05:11:45 < Rickta59> delay is just a busy wait
2012-06-17T05:11:48 < Rickta59> no real time involved
2012-06-17T05:12:02 < szczys> I've got "-O2" in my compiler flags
2012-06-17T05:12:05 < Rickta59> if you are running debug it might be slow
2012-06-17T05:12:08 < szczys> what do you think of that setting?
2012-06-17T05:12:10 < Rickta59> ok .. well then that rules that out
2012-06-17T05:12:24 < zippe> dongs: what's more useful to have on this thing?  I2C or a second receive-only UART?
2012-06-17T05:12:24 < Rickta59> O2 is more optimization than O0
2012-06-17T05:12:41 < Rickta59> -Os for small code size
2012-06-17T05:12:47 < dongs> zippe: well it has enough sensors as far as im concerned.
2012-06-17T05:12:53 < Rickta59> -O2 faster with maybe larger code
2012-06-17T05:13:07 < Rickta59> O2 is good
2012-06-17T05:14:11 < Rickta59> did you try unplugging the usb cable?
2012-06-17T05:14:19 < Rickta59> just wondering if a power cycle might change it
2012-06-17T05:14:41 < szczys> I've tried it, no effect
2012-06-17T05:14:42 < Rickta59> I'm not versed enough with the clocks to know when they can and can't be set
2012-06-17T05:14:49 < szczys> hey, how do I load a .bin file using GDB
2012-06-17T05:14:58 < szczys> I get: is not an object file: File format not recognized
2012-06-17T05:15:05 < Rickta59> heh .. that is why i asked you .. i don't know how to do with with gdb
2012-06-17T05:15:21 < Rickta59> yeah it doesn't really want a bin in gdb .. looking for an elf file
2012-06-17T05:15:37 < Rickta59> there is a bin to elf converter i think
2012-06-17T05:21:06 < zippe> There isn't enough information in a bin file for gdb to do anything useful
2012-06-17T05:21:32 < szczys> this is just silly
2012-06-17T05:21:59 < BrainDamage> can't you use st-link to flash it to the memory?
2012-06-17T05:22:14 < szczys> nope
2012-06-17T05:22:20 < szczys> I got it:
2012-06-17T05:22:34 < szczys> monitor flash write_image orig.bin 0x08000000
2012-06-17T05:22:52 < szczys> but you have to either erase the flash first, or add the word erase before the bin file
2012-06-17T05:24:38 < Rickta59> monitor is a command to gdb to says .. don't do gdb .. talk to the monitor
2012-06-17T05:24:46 < Rickta59> so essentially openocd
2012-06-17T05:25:07 < szczys> yep
2012-06-17T05:25:19 < szczys> I just measured the frequency of both .bin file
2012-06-17T05:25:32 < szczys> the flashing when the program first runs is at 2.5 Hz with the file i compiled
2012-06-17T05:25:41 < szczys> but it's at 5.0 Hz with the bin that ships with it
2012-06-17T05:26:12 < szczys> I don't know if that means anything... but I measured it!!!
2012-06-17T05:26:14 < szczys> heh
2012-06-17T05:26:14 < Rickta59> 200ms .. well that maps
2012-06-17T05:26:25 < Rickta59> do you get 10 Hz at all?
2012-06-17T05:26:35 < Rickta59> should be 10Hz and 5Hz and then off
2012-06-17T05:26:40 < Rickta59> or 5/10/off
2012-06-17T05:26:51 < szczys> okay
2012-06-17T05:27:04 < szczys> that's theoretical from the source code you're looking at?
2012-06-17T05:27:27 < szczys> ummm, you okay flyback?
2012-06-17T05:27:28 < Rickta59> yes but i remember getting those numbers on my scope
2012-06-17T05:27:43 < szczys> on your scope from the BIN file that shipped with it?
2012-06-17T05:27:48 < Rickta59> yes
2012-06-17T05:27:54 < Rickta59> so you are getting the same as me
2012-06-17T05:27:55 < BrainDamage> don't mind flyback, he's like random line noise
2012-06-17T05:27:57 < Rickta59> and matches the code
2012-06-17T05:28:02 < BrainDamage> he's infamous in freenode
2012-06-17T05:28:07 < Rickta59> at least with orig.bin
2012-06-17T05:28:30 < szczys> did you do the math for the source code package?
2012-06-17T05:28:38 < szczys> (sorry to ask the same questions over and over)
2012-06-17T05:28:43 < Rickta59> it is 100ms / 200ms / off
2012-06-17T05:28:58 < Rickta59> 100ms should be 10Hz .. 200ms should be 5 Hz
2012-06-17T05:29:03 < szczys> so it's something wrong with the way I'm compiling it
2012-06-17T05:29:08 < szczys> hmmm....
2012-06-17T05:29:26 < szczys> well.... I'm giving up for the night
2012-06-17T05:29:39 < Rickta59> seems like you are very close
2012-06-17T05:29:42 < Rickta59> thanks
2012-06-17T05:30:00 < szczys> thanks for the help today everyone... I appreciate it
2012-06-17T05:38:12 < szczys> Rickta59 one last thing
2012-06-17T05:38:18 < szczys> you should look at my latest commit
2012-06-17T05:38:31 < szczys> it adds the stm32f0xx_conf.h file to the main Makefile
2012-06-17T05:38:39 < szczys> this makes it really easy to compile the examples
2012-06-17T05:39:11 < szczys> just copy all of the .c to src, and .h to inc (you'll need to find the stm32f0_discovery files too)
2012-06-17T05:39:26 < szczys> and the examples should build without a problem

2012-06-17T20:03:25 < szczys> Is it possible to change the SysTick reload register value from a debugger?
2012-06-17T20:03:42 < szczys> it's at address 0xe000e014 on this chip
2012-06-17T20:03:58 < szczys> and I've tried: monitor mww phys 0xe000e014 0x0000bb7f
2012-06-17T20:04:06 < szczys> but once I resume it reverts back to the old value
2012-06-17T20:04:18 < szczys> it's not running the startup code again when I resume, is it?
2012-06-17T20:05:40 < zippe> szczys: no, it should Just Work
2012-06-17T20:05:52 < zippe> You don't need to use 'monitor' though
2012-06-17T20:06:10 < szczys> I couldn't find a way to change values by address in gdb
2012-06-17T20:06:16 < szczys> the stuff I found only changes variables
2012-06-17T20:06:24 < zippe> set *(uint32_t *)address = value
2012-06-17T20:07:05 < zippe> Alternatively if you have a variable that points to it, use that
2012-06-17T20:07:06 < szczys> No symbol table is loaded.  Use the "file" command.

2012-06-17T20:55:48 < Rickta59> does the systick affect anything in that sample szczys?
2012-06-17T20:56:49 < szczys> rickta59: yep, it's what drives the delay function
2012-06-17T20:57:07 < szczys> so having the interrupt fire twice as fast is what causes it to blink twice as fast
2012-06-17T20:57:35 < Rickta59> k
2012-06-17T20:57:42 < szczys> I'd like to use the debugger to rewrite that register value just for the satisfaction of seeing it respond the same way the compiled code does
2012-06-17T20:57:47 < szczys> but I can't seem to figure out how to do that
2012-06-17T20:57:59 < Rickta59> TimingDelay_Decrement is done by the SysTick interrupt?
2012-06-17T20:58:47 < Rickta59> ah .. there it is
2012-06-17T21:01:47 < szczys> yeah, in my mind the code seems a bit obfuscated
2012-06-17T21:01:50 < Rickta59> is there a simple way to get the output the clock on a pin?
2012-06-17T21:02:12 < szczys> from the stock .bin file?
2012-06-17T21:02:15 < szczys> I doubt it
2012-06-17T21:02:18 < Rickta59> the final clock with all the PLL MUL/ DIVS applied
2012-06-17T21:02:48 < szczys> just load up the two bin files and read the 0xe000e014 register
2012-06-17T21:02:57 < Rickta59> well I know that with the atmega and the msp430 you can set a port register and have it spew out what it thinks is the main clock speed on an external pin as a square wave

2012-06-17T21:03:07 < szczys> you'll get: 0x0000bb7f and 0x00005dbf
2012-06-17T21:03:18 < szczys> that's 48000-1 and 24000-1
2012-06-17T21:03:34 < szczys> the -1 is from the core_m0.h file's definition of the SysTick reload function
2012-06-17T21:03:52 < szczys> and that value is number of cycles that will pass before an interrupt
2012-06-17T21:03:54 < Rickta59> right i mean actually getting it to act like CLKO on an avr
2012-06-17T21:04:09 < Rickta59> and the SMCLK out on the msp430
2012-06-17T21:04:12 < szczys> You'd have to rewrite registers to do it
2012-06-17T21:04:27 < szczys> and I'm not having luck with the cortex peripheral registers right now
2012-06-17T21:04:58 < szczys> relevant regarding writing core registers on F0: http://comments.gmane.org/gmane.comp.debugging.openocd.devel/19440

2012-06-17T21:09:55 < Rickta59> so if all the defines are right .. 48000000/1000 should be the right number of a 1 ms systick

2012-06-18T01:54:35 < drgreenthumb> in /lib/gcc there's other cross compile toolchains, I think it needs to go in /lib/gcc/arm-none-eabi but the layout looks different from whats in my $HOME/toolchain. hrm.
2012-06-18T01:55:02 < drgreenthumb> wonder if I can just copy the tools there. I'll try.

2012-06-18T05:16:11 < drgreenthumb> wait does that actually mean that /usr/local was created today? possible I guess.

2012-06-18T05:17:33 < cjbaird> "find /usr/local -mtime 1 -a -type f" would skip the modified directories.. but yeah, still better to do it manually with that as a guide.

2012-06-18T08:10:51 < zippe> Since the BSD codebase predates Linus' efforts by a good decade or so.
2012-06-18T08:11:06 < pelrun_> so goes the GNU codebase, actually
2012-06-18T08:11:37 < zippe> When you say "the GNU codebase", what do you actually mean?  Since there isn't really a "GNU codebase" in the same sense.
2012-06-18T08:12:00 < pelrun_> yeah, it's a whole bunch of separate tools
2012-06-18T08:12:47 < pelrun_> I'm coming into this conversation right in the middle, so I really shouldn't just make sweeping statements like that without context XD
2012-06-18T08:12:51 < zippe> 8)
2012-06-18T08:13:24 < zippe> Or pick it up with someone that has worked on the BSD code since the mid-90s, who was there for the USL lawsuit, etc. etc. 8)
2012-06-18T08:14:22 < pelrun_> it's not valid to compare the gnu and bsd projects directly anyway - it's not like it's "we do exactly the same thing just with slightly different philosophies"
2012-06-18T08:14:23 < zippe> and CJ, the reason we do the BSD thing is because the GPL is too restrictive.  Some people want to write code that is useful, and the GPL prevents that.
2012-06-18T08:15:00 < zippe> pelrun_: also true.
2012-06-18T08:15:05 < pelrun_> bsd is "we want our code to be used as widely as possible", gpl is "we want our code to help promote 'freedom'"
2012-06-18T08:15:21 < pelrun_> honestly I think both are perfectly valid
2012-06-18T08:16:04 < zippe> pelrun_: sadly, most GPL applications are "because that's what everyone else is using", not even out of some misguided belief in "now with 20% extra freedom in every clause"
2012-06-18T08:16:15 < pelrun_> that's still perfectly fine
2012-06-18T08:16:30 < zippe> As is buying an SUV because you have eight kids.
2012-06-18T08:16:33 < pelrun_> you don't have to be an uber-RMS raving freedom weenie to use it
2012-06-18T08:16:52 < zippe> It doesn't address the dual issue that there are better choices to make than reproducing to that extent
2012-06-18T08:17:04 < zippe> or that you could buy something that moves people more efficiently than an SUV

2012-06-18T08:17:38 < zippe> … as you might guess, I believe in informed consent
2012-06-18T08:17:50 < pelrun_> and really, would you be complaining if people were going bsd purely because 'that's what everyone else is using'?
2012-06-18T08:17:55 < zippe> Yes.
2012-06-18T08:18:10 < zippe> Because that's not a stigma I would want to see attached to the mindset.
2012-06-18T08:18:22 < pelrun_> but you wouldn't be thinking of it in those terms
2012-06-18T08:18:31 < zippe> If someone were to pick a BSD-like license and it was not compatible with their actual aims, I would be unhappy about it.
2012-06-18T08:18:55 < zippe> And in fact on any number of occasions I've advised teams to consider alternative licensing strategies
2012-06-18T08:18:55 < pelrun_> but that's assuming that they actually have consciously chosen 'aims'
2012-06-18T08:19:23 < zippe> It helps to think about it in terms of consequences or outcomes, since you're right, 'aims' is too abstract in many cases.
2012-06-18T08:19:25 < pelrun_> which conflicts with the original assertion that they're just going with the popular choice
2012-06-18T08:20:03 < zippe> Not at all.  The popular choice is the easy one because you just pretend that your aims must be similar to everyone else's
2012-06-18T08:20:31 < pelrun_> and anyway, if you went to one of those people who chose the gpl without thinking about it and ask them 'do you want a big company to take your code that you wrote for free and make money off it' they'd probably say no
2012-06-18T08:21:38 < pelrun_> which is less about their mindset and more about the bias inherent in the question
2012-06-18T08:25:15 < zippe> Aaanyway, this is not a forum for license advocacy; just annoying hearing someone like Chris spewing that sort of pre-teen bile.
2012-06-18T08:29:52 < pelrun_> hehehe, I don't disagree
2012-06-18T09:03:15 < cjbaird> zippe: the BSD codebase before GNU came along wasn't that much. Most of 'their' tools were actually SysV imports that you needed a Unix licence for. GNU started their replacements of the ~30 SysV tools circa 1987; surpassing them in number and quality (gzip instead of compress..) by around 1993. It was until about 1997 that the cult of BSD licensing faggotry took off, and psychos like Theo started ranting..
2012-06-18T09:05:03 < cjbaird> Prior to ~1992, you were expected to be paying all-up about $1k/year/user for the 'free BSD' stuff (and then, people like BSDi tried to keep that going..)
2012-06-18T09:06:52 < cjbaird> Suns were popular about you could get a kind of 'bulk discount' for a multiuser Unix that way-- $20,000 up-front for a Sparc, with 'only' a $3k/year contract&etc. cost thereafter-- which worked out well for Unis and etc.
2012-06-18T09:08:19 < cjbaird> bsd is "we want our code to be used as widely as possible" ... fixed: "we want our code to get me a jerb!" :)
2012-06-18T09:09:48 < cjbaird> A number of the NetBSD coreteam have that attitude. "Oh, Oh! You should embed NetBSD in your products! NO GPL AIDS LOL LOL! ...hey, and there's nobody who understand the code better than me... Gimme jerb!"
2012-06-18T09:11:21 < cjbaird> The drawback being, as of 2012, the lack of any real contributors to NetBSD's code (if we're lucky, someone's Jerb lets them upsteam their work) is only at the stage that Linux was circa 1997..  "Journaling file system? What're those?"

2012-06-18T14:59:34 < karlp> you already pasted that
2012-06-18T14:59:55 < karlp> so, f4 ref man says that flash size register is 0x1fff7a10 + 0
2012-06-18T15:00:09 < karlp> but that's the same address as unique id bits 31:16
2012-06-18T15:00:17 < karlp> L1 and F1 don't overlap like that
2012-06-18T15:00:26 < karlp> I wonder if that's just a datasheet errata
2012-06-18T15:01:01 < karlp> L1 also has the unique id bits at x, x + 4, and x + 0x14
2012-06-18T15:01:09 < karlp> instead of contiguous like the others
2012-06-18T15:01:10 < karlp> weird
2012-06-18T15:02:54 < Thorn> unique id consists of several components: wafer number (or time code?), wafer x/y position, etc.
2012-06-18T15:04:24 < karlp> yeah, but F2 and F4 lists flash size register as having the same address as some of the unique id register bits
2012-06-18T15:04:38 < karlp> which seems odd to have the same addressed listed as two different registers
2012-06-18T15:05:52 < karlp> F0 data sheet actually describes thebits
2012-06-18T15:06:48 < karlp> heh, but doesn't actually say what the base address is.
2012-06-18T15:07:08 < karlp> there's just a blank space beside Base address:

2012-06-18T15:17:19 < Thorn> I've used a few stm32f103vct6 for a project, I think their unique ids differed in a single byte only
2012-06-18T15:17:37 < Thorn> probably all from the same wafer
2012-06-18T15:18:13 < Thorn> and hashing is certainly required

2012-06-18T20:58:02 <+dekar> if you want the easiest way then use an FTDI
2012-06-18T20:58:05 < Rickta59> the host side may not be my program
2012-06-18T20:58:49 <+Steffanx> it takes 5 seconds to install and ftdi driver dekar :P
2012-06-18T20:59:16 <+dekar> Rickta59, our company is shipping a product using USB HID and the experience is great. we basically have an java applet deploy the userland driver and then the browser has access to our device
2012-06-18T20:59:34 <+dekar> Steffanx, you need administrative permissions
2012-06-18T20:59:44 < Rickta59> libusb is already there for java?
2012-06-18T20:59:50 < Rickta59> for all different platforms?
2012-06-18T20:59:58 <+dekar> there are customers using laptops they got from their customers, they don't have admin accounts
2012-06-18T21:00:10 <+dekar> and/or they don't want to install drivers
2012-06-18T21:00:25 < Rickta59> userland driver .. as in you install libusb and and interface? or you provide a socket interface on localhost?
2012-06-18T21:00:27 <+dekar> Rickta59, I am not using libusb
2012-06-18T21:00:42 <+dekar> my device is an HID device
2012-06-18T21:00:50 <+Steffanx> HID is still hacky imho :P
2012-06-18T21:00:55 <+dekar> libusb is a generic usb driver you can install for any device
2012-06-18T21:01:04 <+dekar> Steffanx, your mouse is hackish
2012-06-18T21:01:15 <+Steffanx> No, my mouse is a interface device
2012-06-18T21:01:23 < Rickta59> describe the userland driver
2012-06-18T21:01:30 <+dekar> Steffanx, well yeah I am raping the spec, so what? :)
2012-06-18T21:01:32 < Rickta59> a program or actually a driver
2012-06-18T21:01:45 <+dekar> Rickta59, program contains a driver
2012-06-18T21:01:55 <+dekar> no need to install anything into the system
2012-06-18T21:02:00 < Rickta59> so you have 3 versions for mac/pc/linux?
2012-06-18T21:02:04 < jpa-> so what is dekar's device?
2012-06-18T21:02:04 <+dekar> yeah
2012-06-18T21:02:21 <+dekar> jpa-, http://www.flexoptix.net/flexbox-v2-transceiver-programmer.html
2012-06-18T21:02:40 < jpa-> expensive
2012-06-18T21:03:01 <+dekar> jpa-, does it show up german for you?
2012-06-18T21:03:16 <+dekar> you can change the language at the top
2012-06-18T21:03:32 <+dekar> jpa-, you get one for free if you give feedback :)
2012-06-18T21:03:55 <+dekar> see "V2 feedback campaign"
2012-06-18T21:04:28 < Rickta59> SFP is what?
2012-06-18T21:04:49 <+Steffanx> ethernet crap
2012-06-18T21:05:05 <+Steffanx> Man, i shouldn't talk like dongs
2012-06-18T21:06:01 < Rickta59> so this is a low speed interface?
2012-06-18T21:06:08 <+Steffanx> high speed
2012-06-18T21:06:16 < Rickta59> i mean usb -> sfp device
2012-06-18T21:06:29 < Rickta59> host usb -> stm32 device
2012-06-18T21:06:46 <+Steffanx> Tranciever programmer .. so that thing is just a programmer
2012-06-18T21:07:11 <+Steffanx> for routers, switches and mulltiplexers
2012-06-18T21:07:19 <+dekar> Steffanx, it can also do other stuff, like replaying everything that comes in
2012-06-18T21:07:27 < Rickta59> that seems like a reasonable thing
2012-06-18T21:07:29 <+Steffanx> everything?
2012-06-18T21:07:33 <+Steffanx> over usb dekar ?!
2012-06-18T21:07:42 < Rickta59> did you find it hard to get the usb going on the stm32?
2012-06-18T21:07:45 <+dekar> Steffanx, inside the box, 10G in -> 10G out
2012-06-18T21:07:53 <+Steffanx> ooh

2012-06-18T21:19:52 <+Steffanx> *have = pay
2012-06-18T21:20:06 <+dekar> Steffanx, you can get the unmetered one for 1k more
2012-06-18T21:20:13 <+dekar> check the options
2012-06-18T21:20:25 <+dekar> that only covers transceivers bought from us though
2012-06-18T21:21:09 <+Steffanx> You'll buy your next pc from me?
2012-06-18T21:21:13 <+dekar> being able to tune laser wavelengths (colors) costs another 2k
2012-06-18T21:21:38 <+Steffanx> You pay 100 euro and have to buy credits for every app you try to install and/or compile oyurself :P
2012-06-18T21:22:07 <+dekar> Steffanx, sounds like windows8 for ARM with secure boot

2012-06-18T21:23:13 <+dekar> Steffanx, just get the basic flexBox using the feedback campaign, it is probably the prettiest stm32 board you can get for free :)
2012-06-18T21:23:54 <+Steffanx> I don't have any compatible router/switch/multiplexer
2012-06-18T21:24:23 <+dekar> Steffanx, yet you get an stm32 board with nice case for free
2012-06-18T21:25:04 < karlp> only if you buy 100 transceivers?
2012-06-18T21:25:32 <+dekar> karlp, it doesn't say that?
2012-06-18T21:25:43 <+dekar> just order one cheap SFP :)
2012-06-18T21:25:54 <+Steffanx> cheap?
2012-06-18T21:28:15 <+dekar> Steffanx, like that one: http://www.flexoptix.net/produkte/sfp-sx-1-gigabit-mm-850nm-550m.html
2012-06-18T21:28:34 <+Steffanx> That is programmable?
2012-06-18T21:28:35 <+dekar> I mean it's an epic laser with an effective range of over half a kilometer!
2012-06-18T21:28:57 <+dekar> yeah you can program those using the flexbox
2012-06-18T21:29:28 <+dekar> POSSIBLE COMPATIBILITIES: HP H3C, HP Networking, Huawei, MSA Standard, 3COM, Netgear, Alcatel, Nokia-Siemens (Atrica), Allied Telesis, Nortel, Brocade IP, Brocade Storage, Cisco Systems, Riverstone, D-LINK, Zyxel, Enterasys, Extreme
2012-06-18T21:30:42 <+dekar> you can even have it pogrommed to EXTREME compatibility for free
2012-06-18T21:30:45 <+dekar> EXTREME!
2012-06-18T21:30:47 <+dekar> epic name :)
2012-06-18T21:30:55 <+dekar> I also like their purple switches
2012-06-18T21:31:36 <+dekar> so you buy some pretty EXTREME laser and get a flexbox for free, how's that?
2012-06-18T21:31:51 <+Steffanx> I like the case, but .. :P
2012-06-18T21:32:24 <+dekar> the aluminum is probably worth what you've paid on that transceiver
2012-06-18T21:32:38 <+dekar> so you can sell the EXTREME transceiver plus the aluminum case on ebay :)
2012-06-18T21:32:40 < Rickta59> there is an stm32 inside that?
2012-06-18T21:32:43 <+Steffanx> I actually don't even know what such a transceiver is used for :P
2012-06-18T21:32:51 <+dekar> Rickta59, inside the flexBox2
2012-06-18T21:32:56 <+Steffanx> I mean, i guess you need some compatible device for it?
2012-06-18T21:33:08 <+Steffanx> I'm not into networking at all
2012-06-18T21:33:09 < Rickta59> inside the tranceiver?
2012-06-18T21:34:22 <+dekar> Steffanx, http://img.directindustry.com/images_di/photo-g/rack-mount-industrial-10gbe-ethernet-switch-579210.jpg
2012-06-18T21:34:34 <+dekar> that's where those SFP go into
2012-06-18T21:34:43 <+dekar> into EXTREME switches
2012-06-18T21:35:18 <+dekar> Rickta59, not inside the transceiver, but inside the flexBox V2 which you can get for free with any transceiver order
2012-06-18T21:35:19 <+Steffanx> I get one of those for free too?
2012-06-18T21:35:23 <+dekar> only like 35 left
2012-06-18T21:35:28 <+dekar> Steffanx, nope
2012-06-18T21:35:30 <+Steffanx> Ahr
2012-06-18T21:35:38 < Rickta59> not really useful for me .. but thanks : )
2012-06-18T21:35:43 <+Steffanx> So, i only have a fancy box + transciever for 35e
2012-06-18T21:35:57 <+dekar> it's an EXTREME transceiver!
2012-06-18T21:36:05 <+dekar> compatible to purple switches
2012-06-18T21:36:56 <+dekar> Steffanx, and the flexBox2 is full of goodies
2012-06-18T21:37:03 <+dekar> it has nice blue LEDs
2012-06-18T21:37:10 <+dekar> and a hidden microSD slot
2012-06-18T21:37:16 <+dekar> microUSB as well
2012-06-18T21:37:26 <+dekar> and 2 slots for transceivers
2012-06-18T21:37:29 <+dekar> a heatsink
2012-06-18T21:37:46 <+dekar> oh and pretty neat DC/DC converters
2012-06-18T21:37:54 <+dekar> those uber high efficiency ones
2012-06-18T21:38:39 <+dekar> op-amps...
2012-06-18T21:38:47 <+dekar> Steffanx, you know you want it!
2012-06-18T21:39:02 <+Steffanx> I know i want it, i know it'll end up on my pile of unused goodies
2012-06-18T21:39:23 <+Steffanx> i know it's not worth 35e + shipping
2012-06-18T21:40:22 <+dekar> Steffanx, besides that I am pretty sure our company would lose money on you buying it :P
2012-06-18T21:40:38 <+Steffanx> No
2012-06-18T21:40:42 < karlp> man, this crc block seems to be really crap. you need to bit reverse everything and do it in 32bit chunks not byte chunks
2012-06-18T21:40:54 < TitanMKD> anyone know if there's cache in STM32F4 ?
2012-06-18T21:41:09 <+dekar> TitanMKD, like the prefetch thing?
2012-06-18T21:41:13 < TitanMKD> it is not clear if cache is implemented or not on ARM M3/M4
2012-06-18T21:41:26 < TitanMKD> dekar yes and how many cache memory is available
2012-06-18T21:41:48 < TitanMKD> to know also if ARM instruction for cache are available ;)
2012-06-18T21:41:59 <+dekar> TitanMKD, I am pretty sure the stm32f1 has the prefetch buffer
2012-06-18T21:42:08 <+dekar> and I think it is enabled by default
2012-06-18T21:42:51 < TitanMKD> the branch predictor seems always here on M4
2012-06-18T21:43:04 < TitanMKD> with a 3 stage pipeline
2012-06-18T21:43:39 <+dekar> one would think stuff like that doesn't matter on a three stage pipeline -.-"
2012-06-18T21:44:00 < TitanMKD> the branch predictor is very important too
2012-06-18T21:44:09 <+dekar> cortex M5 will probably do out-of-order execution :P
2012-06-18T21:44:52 < TitanMKD> in fact i'm benchmarking LPC4330 which boot on SPIFI and it seems it has cache because basic code with 100nop loop execute more than 190 millions instructions per second @204MHz
2012-06-18T21:45:25 < TitanMKD> and the SPIFI max speed is 50MB/s (@more than 100MHz)
2012-06-18T21:46:05 <+dekar> TitanMKD, execution from ram isn't an option?
2012-06-18T21:46:15 < TitanMKD> dekar i tested it too with same speed ;)
2012-06-18T21:46:21 <+dekar> wow nice :)
2012-06-18T21:46:36 < TitanMKD> it is why i will add some test to know what's the cache size by increasing the test code ...
2012-06-18T21:46:58 < TitanMKD> and also by checking SPIFI access with Logic Analyzer to confirm code is not executed from SPIFI
2012-06-18T21:47:23 < TitanMKD> it is just not documented at all in any documentation
2012-06-18T21:47:55 <+dekar> TitanMKD, if our wiki was ready we could document your findings there :/

2012-06-18T21:49:15 <+izua> but just .ro for romania
2012-06-18T21:49:16 <+dekar> I like .ro
2012-06-18T21:49:22 <+izua> also, hitler.su
2012-06-18T21:49:22 <+dekar> better than .de for Germany

2012-06-18T21:50:24 <+Steffanx> So is .ro dekar
2012-06-18T21:51:10 <+izua> .ro is not a domain hack
2012-06-18T21:51:15 <+izua> it's epicness in a box
2012-06-18T21:51:29 <+izua> you get a per-life domain for $30
2012-06-18T21:54:07 <+dekar> neat
2012-06-18T21:54:15 <+dekar> ours are like 2€ per year
2012-06-18T21:54:36 <+izua> well
2012-06-18T21:54:51 <+dekar> I can't stand .de though

2012-06-18T22:00:00 <+izua> you could do worse
2012-06-18T22:00:00 < Rickta59> that wouldn't be my preference

2012-06-18T22:00:32 <+Steffanx> No, web based is the only option
2012-06-18T22:00:57 <+dekar> Steffanx, JS ftl
2012-06-18T22:00:59 <+izua> speaking of webstuff
2012-06-18T22:01:03 < Rickta59> ok .. so no one has seen anything like that?
2012-06-18T22:01:06 <+dekar> it doesn't even do threading
2012-06-18T22:01:16 <+Steffanx> It does dekar
2012-06-18T22:01:20 <+dekar> no waii
2012-06-18T22:01:24 <+izua> is there an xml or some other similar thing that has a memory map of the F1 chips? (or maybe even the F2 or F4)
2012-06-18T22:01:28 <+Steffanx> web workers dekar
2012-06-18T22:01:29 <+dekar> Steffanx, proof?
2012-06-18T22:01:32 <+dekar> O.o
2012-06-18T22:01:35 <+Steffanx> Not implemented very well  yet, but it does exist
2012-06-18T22:01:49 <+izua> i'm curious to make a diff on them, and see how better chips overlay to the entry level ones
2012-06-18T22:02:00 <+dekar> Steffanx, one of those weird Mozilla only things? Like WebVibrator (vibration api)
2012-06-18T22:02:09 < Rickta59> you can just use frames to get threading
2012-06-18T22:02:18 <+izua> why would one choose such a horrible nickname for a project
2012-06-18T22:02:27 <+Steffanx> Not sure which browser implement it dekar
2012-06-18T22:02:32 < drgreenthumb> yeah it should have been called remote teledildonics!
2012-06-18T22:02:51 < drgreenthumb> bzzzzzzz
2012-06-18T22:03:03 < drgreenthumb> nice wiki :P

2012-06-18T22:11:29 <+izua> and a lot of javascript and ads and background music
2012-06-18T22:15:24 < Rickta59> animated GIF files are much tackier
2012-06-18T22:16:44 < Laurenceb_> <marquee>
2012-06-18T22:16:59 < BrainDamage> quick chibios question: in the docs, with pwm period, do they actually mean semiperiod? because there seems to be a separate parameter for the frequency
2012-06-18T22:20:23 <+izua> <blink>
2012-06-18T22:21:47 <+izua> uh, what if one is the prescaler, and the other one is the frequency?
2012-06-18T22:22:43 <+Steffanx> Everything is better than that default logo+text  izua
2012-06-18T22:23:30 <+izua> i was thinking of installing the gumax (:google) theme
2012-06-18T22:23:38 <+izua> it's looks much more clean and nice then mediawiki
2012-06-18T22:24:26 <+izua> hm
2012-06-18T22:24:41 <+izua> dongs had a neat picture where he ran 12v across a 5v tolerant p[in
2012-06-18T22:25:06 < BrainDamage> that reminds me we still didn't see the exploded stm32 pic from Laurenceb
2012-06-18T22:25:20 <+Steffanx> Laurenceb_ made a photo of his stm32 yet?

2012-06-18T22:25:26 < Laurenceb_> i chucked it sorry
2012-06-18T22:25:46 < Laurenceb_> almost like that
2012-06-18T22:25:52 < Laurenceb_> is thats a dongs board?
2012-06-18T22:26:07 <+Steffanx>  /ban-for-life Laurenceb_
2012-06-18T22:26:20 < Laurenceb_> why?
2012-06-18T22:26:30 <+Steffanx> You didn't take a photo
2012-06-18T22:26:48 < Laurenceb_> heh
2012-06-18T22:26:54 < Laurenceb_> thats some quality pcb fab
2012-06-18T22:27:04 < Laurenceb_> wish i could find somewhere that good
2012-06-18T22:28:25 < jpa-> i made an add-on to my stm32 board: http://koti.kapsi.fi/jpa/stuff/pix/SANY0016.JPG
2012-06-18T22:29:06 < BrainDamage> that looks much more professional to the previous pic
2012-06-18T22:29:12 < Laurenceb_> hehe
2012-06-18T22:29:23 <+Steffanx> yuck .. what's that jpa- ?
2012-06-18T22:29:57 < jpa-> BrainDamage: they actually mean the number of ticks per period.. ie. if you set 12000000, 600  you get 12MHz timer with 600 tick PWM period
2012-06-18T22:30:10 < jpa-> (=> 20kHz PWM)
2012-06-18T22:30:35 < BrainDamage> ah, to set the resolution? thanks
2012-06-18T22:30:53 < jpa-> Steffanx: capacitor pump to raise 4V -> 5V :)
2012-06-18T22:31:01 < jpa-> driven from IO pin
2012-06-18T22:31:11 < jpa-> BrainDamage: yeah
2012-06-18T22:31:19 <+Steffanx> And what is it used for (the board)
2012-06-18T22:31:27 < jpa-> still the sphere
2012-06-18T22:31:34 <+Steffanx> Oh ok
2012-06-18T22:31:43 <+Steffanx> You also needed the standby for that?
2012-06-18T22:31:51 < jpa-> yeah, it has no power switch
2012-06-18T22:32:03 < jpa-> i'm finally starting to get it actually working
2012-06-18T22:32:09 < Rickta59> szczys are you here?
2012-06-18T22:32:53 < jpa-> note-to-self: inverting the Z channel measurements is not an easy fix to sign errors. it makes your coordinate system left-handed, and no-one likes lefties
2012-06-18T22:33:37 -!- neuro-sys [~neuro@unaffiliated/neurosys/x-283974] has joined ##stm32
2012-06-18T22:34:09 <+izua> jpa-: did you make that board at home?
2012-06-18T22:34:18 < jpa-> izua: yeah
2012-06-18T22:34:30 <+izua> details please?
2012-06-18T22:34:34 <+Steffanx> I stopped doing that after a little accident
2012-06-18T22:34:40 < jpa-> laser printer + photoresist
2012-06-18T22:34:43 <+izua> i was barely able to obtain 0.15mm features on a 1kW lamp
2012-06-18T22:34:58 < jpa-> bright fluorescent desk lamp
2012-06-18T22:35:00 <+izua> jpa -v -v
2012-06-18T22:35:26 <+Steffanx> No UV?
2012-06-18T22:35:26 <+izua> so, you impressed it with a desk lamp
2012-06-18T22:35:27 < jpa-> the real trick is to have a good print quality
2012-06-18T22:35:37 <+izua> CFLs have quite some UV noise
2012-06-18T22:36:06 <+izua> i've used one of those bigass hg discharge bulbs to get uv, and about 500mm distance from the light, to get little reflections
2012-06-18T22:36:09 < jpa-> then you can happily expose for 20 minutes and get good contrast (transparency with inkside against the board)
2012-06-18T22:36:27 <+Steffanx> 20 minutes .. i only needed 2-3 minutes
2012-06-18T22:36:32 <+izua> nah, i got 5 minute tops
2012-06-18T22:36:42 <+izua> but traces were often broken or thinner
2012-06-18T22:36:44 < jpa-> yeah, depends on your lamp & age of the board
2012-06-18T22:36:58 < jpa-> 10 minutes when the board is new, 20 minutes when it is 3 years old
2012-06-18T22:37:10 <+Steffanx> Your boards get old?
2012-06-18T22:37:13 <+izua> so you only printed on transparency?
2012-06-18T22:37:18 <+izua> the photoresist becomes less reactive
2012-06-18T22:37:20 < jpa-> izua: yeah
2012-06-18T22:37:26 < jpa-> Steffanx: if the resist is pre-applied
2012-06-18T22:37:41 <+izua> i do that to, but i also used calc(?) paper
2012-06-18T22:37:41 < jpa-> if you spray it on yourself not as much.. but not sure if the spray will age
2012-06-18T22:37:47 <+izua> uhm
2012-06-18T22:37:57 <+Steffanx> I used that izua
2012-06-18T22:37:58 <+izua> tracing paper*
2012-06-18T22:38:03 <+izua> that's the term
2012-06-18T22:38:20 < jpa-> too bad i only have 4 good transparency films left.. i bought new ones but they don't work as well
2012-06-18T22:39:30 <+izua> i have tried a lot of tricks to get such small details
2012-06-18T22:39:44 <+izua> and i couldn't get repetability at all
2012-06-18T22:39:53 < jpa-> but that board only has 0.2mm details anyway
2012-06-18T22:40:06 < jpa-> that's the smallest i can reliably manage
2012-06-18T22:40:46 < BrainDamage> the traces look rather sharp tough
2012-06-18T22:41:22 <+izua> would you care do give more details about your setup and boards?
2012-06-18T22:41:26 < jpa-> yeah, but i sometimes have trouble with extra dots or gaps in the printout
2012-06-18T22:41:51 <+izua> i'm interested in the specific light source, distance between the film and light and developer
2012-06-18T22:42:28 <+izua> jpa-: what i do against that is make a 45 degree fill
2012-06-18T22:42:37 < jpa-> izua: nothing special.. the number one important thing is to have a good printout and then make sure the ink is pressed close against the board surface
2012-06-18T22:42:51 <+izua> definitely check.
2012-06-18T22:42:59 <+izua> i have even tried with two transparencies overlaid
2012-06-18T22:43:07 < jpa-> 45 degree fill where?
2012-06-18T22:43:18 <+izua> everywhere
2012-06-18T22:43:24 < jpa-> what is 45 degree fill?
2012-06-18T22:43:35 < jpa-> two transparencies works, but ruins detail
2012-06-18T22:43:43 <+izua> whoopsie, sorry, i'm a bit tired
2012-06-18T22:43:49 <+izua> it's.. err... poly fill?
2012-06-18T22:43:53 <+izua> i can' tremember the exact term
2012-06-18T22:44:05 < jpa-> so how does it help?
2012-06-18T22:44:07 <+izua> you cover the whole board in a pattern, like on millimetric paper
2012-06-18T22:44:16 <+izua> the empty spaces, actually
2012-06-18T22:44:21 < jpa-> ah, for ground plane
2012-06-18T22:44:23 <+izua> you don't get dots and gaps
2012-06-18T22:44:30 <+izua> well, yeah, it could be a ground plane
2012-06-18T22:44:44 < jpa-> hmm.. why does it stop dots and gaps?
2012-06-18T22:44:58 < jpa-> i mean they don't hurt in the empty space anyway :)
2012-06-18T22:44:59 <+izua> it ensures faster and less loss of details during etching
2012-06-18T22:45:18 < jpa-> ah, true
2012-06-18T22:45:20 <+izua> and there won't be any dots, at least, not bigger than your minimum trace width in the plane
2012-06-18T22:45:42 < jpa-> but my dots & gaps don't occur at the etching stage
2012-06-18T22:45:43 <+izua> plus, you can tell apart boards with exposure problems pretty fast
2012-06-18T22:46:06 < jpa-> instead they are there after exposure & developing
2012-06-18T22:46:30 < jpa-> i think problem may be dust :P
2012-06-18T22:46:41 < jpa-> and crappy printer does some of those also..
2012-06-18T22:50:12 <+izua> my old printer exhibeted some very strange behaviour (a hp1020)
2012-06-18T22:50:59 <+izua> if i printed lines parallel to the feeding direction (only that) they all came out washed
2012-06-18T22:51:12 <+Steffanx> :S
2012-06-18T22:51:22 <+Steffanx> At least my 1022 doesn't have that problem
2012-06-18T22:51:25 <+izua> if i printed the perpendicular to it (on the laser axis) some sort of interference pattern was created :D
2012-06-18T22:51:50 <+izua> when i added a ground grid, at 45 degrees, the problem went away :D
2012-06-18T22:51:50 <+izua> hehe
2012-06-18T22:52:13 <+izua> i have a new one for some time, a 1102, but i haven't tested how it prints transparencies yet.
2012-06-18T22:52:21 <+Steffanx> I guess HP designed it for next and nothing else but text
2012-06-18T22:52:31 <+Steffanx> */next/text
2012-06-18T22:53:12 <+izua> jpa-: what printer are you using for transparencies?
2012-06-18T22:59:30 < jpa-> izua: hp color laserjet 1600
2012-06-18T23:11:01 < TitanMKD> haha great i see access to SPIFI in realtime ;)
2012-06-18T23:11:20 <+Steffanx> ...
2012-06-18T23:11:40 < TitanMKD> there's 1 access each 1s so it is cached
2012-06-18T23:13:23 <+dekar> TitanMKD, nice! what logic analyzer are you using?
2012-06-18T23:15:23 < TitanMKD> dekar i'm checking it with my Scope in fact
2012-06-18T23:15:50 < TitanMKD> i know the SPIFI access is executed only when instruction flow is "broken" by the while(1)
2012-06-18T23:15:57 < TitanMKD> executed exactly each 1s ;)
2012-06-18T23:18:13 < TitanMKD> dekar the code loop is here http://pastie.org/4110506
2012-06-18T23:18:39 < TitanMKD> so it is interesting bl to gpio_clear ... are in fact all cached
2012-06-18T23:19:29 < TitanMKD> dekar SPIFI Clock is 22.73MHz ;)
2012-06-18T23:24:36 < TitanMKD> and it load only 32bytes each 1s
2012-06-18T23:29:00 < TitanMKD> dekar it means 32bytes=256bits so if just fill a full cache line at each instruction flow interruption of the while(1) branch to the start

2012-06-18T23:45:44 <+dekar> new xbox architecture
2012-06-18T23:45:50 <+dekar> looks somewhat weird to me
2012-06-18T23:45:59 <+dekar> bazillions of cores
2012-06-18T23:46:02 <+dekar> PPC and ARM
2012-06-18T23:50:34 <+izua> security system
2012-06-18T23:50:37 <+izua> always on
2012-06-18T23:51:04 <+izua> why would i want a core wasting power just so it can.. wait, what advantage does that even offer ot the end user?
2012-06-18T23:51:58 < Laurenceb_> hmm
2012-06-18T23:52:06 < Laurenceb_> chibios uses dma for the peripherals
2012-06-18T23:52:23 < Laurenceb_> and looks like it generates an error if the dma channel is already allocated
2012-06-18T23:52:26 < Laurenceb_> seriously lame
2012-06-18T23:52:34 < Laurenceb_> it just errors
2012-06-18T23:52:58 < Laurenceb_> its particularly limiting on F1
2012-06-18T23:55:20 <+dekar> izua, it receives emails etc while in standby I guess
2012-06-18T23:55:33 <+dekar> on the other hand, my phone does that already
2012-06-18T23:55:38 <+izua> why?
2012-06-18T23:55:46 <+izua> i mean mail servers are already up 24/7
2012-06-18T23:56:30 <+dekar> it probably plays some loud windows error sound every time and demands you to delete some mails from your inbox so it can receive the latest spam :D
2012-06-18T23:56:50 <+dekar> idk, maybe video calls?
2012-06-18T23:57:00 <+dekar> it could ring telling you someone is calling
2012-06-18T23:57:12 <+dekar> didn't m$ buy Skype?

2012-06-19T00:09:00 < Laurenceb_> seems like a bit of a fail by chibios
2012-06-19T00:09:25 < Laurenceb_> i guess it makes the drivers simple to just use dma, but an option for interrupt driven would be nice

2012-06-19T00:25:21 < TitanMKD> it seems some beta are running but for official update i do not know
2012-06-19T00:25:51 < TitanMKD> Steffanx I hope it will be 0 wait state Dual Flash Bank like the STM32F4
2012-06-19T00:26:01 < TitanMKD> except STM32F4 has only 1 bank ;)
2012-06-19T00:26:56 < TitanMKD> haha no test 200nop and the same 5millions cycles per sec ;)
2012-06-19T00:27:14 < Rickta59> http://hackaday.com/2012/06/17/template-for-building-stm32f0-discovery-project-in-gcc/#comments ...
2012-06-19T00:27:48 < Rickta59> does anyone have suggestions on how to deal with the comment about not distributing the stm32_flash.ld file?
2012-06-19T00:28:27 < Rickta59> aren't just about all gcc based ld scripts going to look remarkably similar give the startup file that is supplied?
2012-06-19T00:29:19 <+Steffanx> dekar and his legal issues all the time
2012-06-19T00:29:36 < Rickta59> Elias Önal  is dekar?
2012-06-19T00:30:02 <+Steffanx> Yes
2012-06-19T00:30:38 < Rickta59> I mean obviously you can copy the file from the st download as they are the ones providing it ..
2012-06-19T00:30:59 < Rickta59> or i could go make my own but it going to have to look very similar
2012-06-19T00:31:16 <+izua> 17 june
2012-06-19T00:31:20 <+izua> elias oenal
2012-06-19T00:31:28 <+izua> oh look, dekar is being the friendly neighbourhood troll
2012-06-19T00:31:50 <+izua> if you make your own, there shouldn't be a problem
2012-06-19T00:32:04 < Rickta59> my point is if i make my own it is going to look like that
2012-06-19T00:32:22 < Rickta59> it is like saying main can't look like another main
2012-06-19T00:32:22 <+Steffanx> No one can proof you didn't make it yourself :P
2012-06-19T00:32:36 <+izua> it isn't atollic that owns the memory layout
2012-06-19T00:32:56 < Rickta59> but they put restrictive warnings on there
2012-06-19T00:33:01 <+izua> plus, there is no way to prove that for a given problem, two equally good programmers will never reach the same conclusion
2012-06-19T00:33:14 <+izua> and this isn't even a problem
2012-06-19T00:33:17 <+Steffanx> And there are enough alternatives ...
2012-06-19T00:33:41 < Rickta59> right i found sites that have alternate linker scripts .. surprise .. they look very similar
2012-06-19T00:34:05 < Rickta59> http://www.triplespark.net/elec/pdev/arm/stm32.html .. i could use that one and change the addresses and length to fit
2012-06-19T00:34:18 <+Steffanx> yeah
2012-06-19T00:34:35 < Rickta59> so what are they protecting by putting that warning on there?
2012-06-19T00:35:01 <+izua> EVERYTHING
2012-06-19T00:35:31 < Rickta59> the rest of the CMSIS stuff is all there to grab
2012-06-19T00:36:44 <+izua> yeah, but that doesn't belong to atollic
2012-06-19T00:37:40 < Rickta59> http://lmgtfy.com/?q=Abstract+%3A+Linker+script+for+STM32
2012-06-19T00:38:11 < Rickta59> and it is part of the samples that STM provides
2012-06-19T00:40:56 <+izua> oh.
2012-06-19T00:41:14 <+izua> then i don't know. they're just being dicks?
2012-06-19T00:41:25 <+izua> atollic was pretty neat afaik
2012-06-19T00:41:40 <+izua> it had a nag message which forced me to move the mouse and click "ok"
2012-06-19T00:41:41 <+dekar> yeah that was me :)
2012-06-19T00:41:47 <+izua> each time i programmed the board
2012-06-19T00:41:52 < Rickta59> is it anymore than a company providing support for the open source tools?
2012-06-19T00:42:16 < Rickta59> is atollic eclipse based?
2012-06-19T00:42:21 <+izua> it also provides an ide
2012-06-19T00:42:32 <+dekar> Rickta59, I am using a modified linker script under a more permissive license, want a copy?
2012-06-19T00:42:35 <+izua> nah
2012-06-19T00:42:48 < Rickta59> sure
2012-06-19T00:42:53 < Rickta59> pastebin it

2012-06-19T00:43:28 <+dekar> that's what I use for TNT
2012-06-19T00:43:56 < Rickta59> heh .. ok .. to my point
2012-06-19T00:44:08 < Rickta59> it looks remarkably similar to the atollic one
2012-06-19T00:44:58 < Rickta59> but thanks
2012-06-19T00:45:19 <+dekar> Rickta59, so are you mike?
2012-06-19T00:45:28 < Rickta59> no that is szczys
2012-06-19T00:45:43 <+dekar> ah, so someone pass it to him if he needs one
2012-06-19T00:46:10 <+dekar> you might wanna adjust things like stack size (I changed it to 8k iirc)
2012-06-19T00:46:16 < BrainDamage> nothing better than a catastrophic failure on your dcdc controller leaking into the logic side and frying your 3$ micro
2012-06-19T00:46:21 <+dekar> and probably flash and ram regions
2012-06-19T00:46:22 < Rickta59> the point is if you strip modify it to work with the m0 board .. it is just going to end up looking like the atollic stuff
2012-06-19T00:46:36 < Rickta59> s/strip//
2012-06-19T00:47:08 <+dekar> the point is as long as you've never looked at their script it is legal :)
2012-06-19T00:47:19 <+dekar> couldn't be stolen in that case

2012-06-19T04:02:41 < Rickta59> when you use INCLUDE in a linker script does it use the -I paths passed to the gcc line?
2012-06-19T04:03:16 < dongs> isnt -I for preprocessor
2012-06-19T04:03:33 < Rickta59> probably .. that is why I'm asking
2012-06-19T04:05:31 < Rickta59> nm .. "Include the linker script filename at this point. The file will be searched for in the current directory, and in any directory specified with the -L option. You can nest calls to INCLUDE up to 10 levels deep."
2012-06-19T04:05:53 < dongs> -L makes sense
2012-06-19T04:05:57 < dongs> since thats trash passed to linker
2012-06-19T04:07:24 < zyp> correct

2012-06-19T07:34:24 < zippe> cjbaird: "why was there never a free-pc-unix scene like Linux had back in the 1980s" … hmm.
2012-06-19T07:34:54 < zippe> cjbaird: Perhaps you might re-read http://en.wikipedia.org/wiki/Linux - at least the first paragraph.
2012-06-19T07:46:40 < cjbaird> The context from the entire line was about a free/cheap BSD pc-unix scene. I was there. Yes, there was Minix($150), Coherent($299), Xenix($1000), i86($3000), et.al. BSD had little free input into those-- and then, it was having to then pay an extra $800+ for the Xenix BSD layer. The 'bsd people' were too busy trying to become the next Bill Joy with "wanna buy a free compiler, mate?"
2012-06-19T07:48:13 < cjbaird> Also, I'm talking about the 1980s, when BSD ports to the 80286 were 'common', but never shared.
2012-06-19T07:48:26 < zippe> mm, yes, I was there too, and my point remains - there was no "free-pc-unix scene like linux had in the 80s" because there was no linux in the 80s.
2012-06-19T07:48:42 < cjbaird> The supposedly 'open source' that Ken Pick et.al. want to claim was anything but.
2012-06-19T07:49:03 < cjbaird> unix != linux, fuckknob.
2012-06-19T07:49:49 < cjbaird> The freest 'unix-alike' available at the time was probably Xinu.
2012-06-19T07:50:33 < blkcat> why are we discussing the 1980s
2012-06-19T07:50:36 < blkcat> what does this have to do with anything
2012-06-19T07:50:36 < zippe> Yeah, that's a great way to carry your argument.  I'm waiting for you to explain how there was, as you have said, "a free-pc-unix scene like Linux had back in the 1980s" when there was no Linux in the 1980s.
2012-06-19T07:52:27 < dongs> blkcat: the fact that its 2012 and lunix is still shit.
2012-06-19T07:52:36 < zippe> blkcat: I'm waiting for an I2C test to fail, and taunting an incoherent greybeard like cj here is better than picking my toenails
2012-06-19T07:52:38 < blkcat> yeah, it kind of is. :\
2012-06-19T07:52:38 < dongs> probably why they're discussing it while waiting for kernel 3.x.3.2.312.4. to finish compiling
2012-06-19T07:52:39 < cjbaird> for the comprehensionally-challenged: "a free-pc-unix scene like Linux had (in the 1990s) back in the 1980s"
2012-06-19T07:52:43 < dongs> just to find out it sucks as much as the one before.
2012-06-19T07:52:47 < blkcat> i'd much rather use free/openbsd myself.
2012-06-19T07:52:59 < dongs> i'd much rather just use windows, since it works
2012-06-19T07:53:29 < zippe> It's people like him that made dealing with APANA substantially less fun than product testing for Mr S. Leathers and Fetters.
2012-06-19T07:53:53 < blkcat> windows is also a fine choice. ditto os x.
2012-06-19T07:53:56 < blkcat> the right tool for the right job.
2012-06-19T07:54:12 < zippe> Various linux distributions are also right tools for some jobs
2012-06-19T07:54:18 < cjbaird> The BSD tools back in the 1980s /sucked/. If they were installed, it was so people could get the Pascal tools. GNU came along in the late 1980s and made things that worked.
2012-06-19T07:54:37 < dongs> ha ha.
2012-06-19T07:54:40 < zippe> cjbaird: For some value of "worked" that made any number of compiler vendors a lot of money.
2012-06-19T07:55:02 < zippe> … speaking of someone that was making a living building software for the 68k in those days.
2012-06-19T07:55:08 < zippe> s/of/as/
2012-06-19T07:56:15 < zippe> There was a lot of interesting and sometimes even useful software floating around from any number of sources.
2012-06-19T07:57:14 < cjbaird> Yes, a Usenet feed was a _must_have_ back then. :)
2012-06-19T07:57:15 < zippe> When you say "GNU", I am at something of a loss as to what you might mean, though.
2012-06-19T07:57:26 < dongs> GNU/RMS
2012-06-19T07:57:41 < zippe> Since "GNU" was largely something that RMS grunted in moments of passion (according to someone that ought to know).
2012-06-19T07:58:12 < dongs> does hurd boot on non-386 hardware yet
2012-06-19T07:58:20 < zippe> If you mean "GNU-licensed software", that's one thing.  If you mean "code that RMS wrote", that's quite another.
2012-06-19T07:59:36 < cjbaird> The subject was GNU vs. BSD userland at one point...
2012-06-19T07:59:37 < zippe> I doubt that you'd refer to Catholic or Methodist software, but that's about the same as your use of the GNU label...
2012-06-19T07:59:46 < zippe> What GNU userland?
2012-06-19T08:00:01 < zippe> There were some replacements for the SysV tools that were GNU-licensed.
2012-06-19T08:00:11 < zippe> There were some that were BSD or MIT-licensed.
2012-06-19T08:00:18 < zippe> Others in the public domain, etc.
2012-06-19T08:00:58 < zippe> It took crazies like Volkerding to try to build a complete system out of tools sharing a mostly common license.
2012-06-19T08:02:09 < zippe> By contrast, around that time you could 'make world' in a Lite/2 source distribution and have a complete system image after a day or so.
2012-06-19T08:03:30 < zippe> I'm still at a loss as to why after twenty-something years, someone of your alleged maturity feels the need to get all pubescent about someone that works on a particular toolset.  But it's sure fun to watch. 8)
2012-06-19T08:04:02 < zippe> And excellent.  Either Honeywell or ST have dropped the bucket, and the bits are dripping off the bus.
2012-06-19T08:04:40 < zippe> dongs: I have a reworked makefile for you - should I file an issue on your g!code project?

2012-06-19T10:02:45 < dongs> thats fine
2012-06-19T10:02:53 < dongs> most dudes will be building one or another nayway.

2012-06-19T10:03:50 < dongs> did you ever confirm the pinout was different?
2012-06-19T10:03:57 < zippe> Yeah, it definitely is

2012-06-19T10:06:34 < zippe> What's incomprehensible to me is that the main board has PA2 on it, but they don't use it...
2012-06-19T10:06:55 < zippe> i.e. it's routed out to where they could have pulled it onto the I/O board.  Oh well.
2012-06-19T10:06:57 < dongs> you mean to use as timer input?
2012-06-19T10:07:13 < zippe> Yeah, instead of whatever wackery they have to use for PA4
2012-06-19T10:07:19 < dongs> EXTI :(
2012-06-19T10:07:24 < dongs> but at least you got enough free timers
2012-06-19T10:07:29 < dongs> just wont be as accurate
2012-06-19T10:07:32 < zippe> If I ever use it, it'd be an ADC
2012-06-19T10:07:33 < dongs> you can just waste TIM5 or osmeshit on it
2012-06-19T10:07:46 < dongs> youll just use PPM input?
2012-06-19T10:07:49 < zippe> yeah
2012-06-19T10:07:54 < dongs> thats what I figured :09
2012-06-19T10:07:58 < dongs> thats why I never bothered fixing it.
2012-06-19T10:08:05 < zippe> I can't see the point of PWM input anymore
2012-06-19T10:08:12 < dongs> who teh fuck would want only 4 channels anyway
2012-06-19T10:08:56 < zippe> When you can buy a D4FR or a D4R-II for twenty-something bucks ...
2012-06-19T10:09:49 < dongs> yeah..
2012-06-19T10:09:57 < zippe> Of course, they released the D4R-II just after I bought a bunch of D6FRs
2012-06-19T10:10:02 < dongs> heh

2012-06-19T10:10:29 < dongs> the range was much worse compared to D8R, but it might have been interference from elsewhere
2012-06-19T10:10:38 < zippe> huh. interesting

2012-06-19T10:11:55 < R0b0t1> Also about the code protection bug mentioned in the topic:
2012-06-19T10:12:10 < R0b0t1> "1. Intruder loads code (via System Boot Loader) into the beginning of RAM and after Reset the ST32 boots from this RAM. He is getting control over the processor and his procedure is easily copying my precious code from flash to ram and next via USART, SPI…."
2012-06-19T10:12:20 < R0b0t1> Counterpoint 1) No one cares about your "precious code".
2012-06-19T10:12:33 < dongs> R0b0t1: loooooooooooooooooooooooooooooooooooooooooooooooooooooooooool.
2012-06-19T10:12:41 < dongs> R0b0t1: obviosuly you've never worked anywhere or developed any sort of commercial product.
2012-06-19T10:13:09 < zippe> R0b0t1: You have successfully described about 90% of the hackerverse.  Your point?
2012-06-19T10:13:11 < R0b0t1> The only people who care about their "precious code" is _maybe_ the programmer, but usually some person in management.
2012-06-19T10:13:22 < R0b0t1> If you are looking for something secure, you secure the CPU physically.
2012-06-19T10:13:37 < dongs> i need to do the ram attack shit and grab STLink's bootloader.
2012-06-19T10:13:38 < zippe> R0b0t1: and yourself, it seems
2012-06-19T10:13:39 < dongs> im so fucking lazy.
2012-06-19T10:14:00 < dongs>  i used real stlinkv2 yesterday
2012-06-19T10:14:01 < R0b0t1> zippe: I care in a different way!
2012-06-19T10:14:03 < dongs> the  one in oval case
2012-06-19T10:14:09 < dongs> it was uploading at 32k/sec on WINDOWS
2012-06-19T10:14:13 < dongs> using official ST drivers
2012-06-19T10:14:14 < dongs> utter total fail
2012-06-19T10:14:15 < zippe> dongs: mine is still on backorder. 8(
2012-06-19T10:14:39 < dongs> for the same price you can get clone jlink/ulink and it will be 230894239048x faster
2012-06-19T10:15:07 < R0b0t1> The main issue is that ultimately the code protection does crap, even for those hardened µCs and SoCs they have for ATMs and point-of-sales terminals. The largest portion of security comes from limiting access to the chips, and physically securing them inside the product.
2012-06-19T10:15:15 < R0b0t1> If someone _wanted_ to get in there, they could.
2012-06-19T10:15:22 < R0b0t1> But no one does. Because no one cares.
2012-06-19T10:15:51 < zippe> Er, they do, and they do.
2012-06-19T10:15:57 < dongs> ^
2012-06-19T10:16:23 < zippe> Some portion of those that care can't afford to do vs. certain levels of protection
2012-06-19T10:16:41 < zippe> e.g the Flylogic guys are still 5 figures for a readout, and they're so overbooked it takes months
2012-06-19T10:17:08 < dongs> we pushed some shit through them. about 80k worth.
2012-06-19T10:17:15 < dongs> fucker still owes some data though
2012-06-19T10:17:16 < dongs> been almost 2 years.
2012-06-19T10:17:34 < zippe> Yup
2012-06-19T10:17:47 < zippe> And I think he's still not set up for 45nm
2012-06-19T10:17:55 < zippe> Chipworks might be able to work there.
2012-06-19T10:18:23 < zippe> In fact, is he even doing 65?
2012-06-19T10:18:40 < zippe> You might actually be able to buy a current-generation micro that can't be university-lab FIB'ed.
2012-06-19T10:18:58 < dongs> haha.
2012-06-19T10:19:08 < zippe> Of course, if you are having your CM program the device, you're an idiot
2012-06-19T10:19:33 < zippe> Because 9mm Para is cheap, and your CM's employees have family
2012-06-19T10:20:30 < zippe> (and they're stupid, too.  Look at the idiots leaking Apple parts to the press… way to fuck your company over)

2012-06-19T12:25:37 < karlp> at some point it's limited by the actual flash
2012-06-19T12:25:42 < karlp> but what speed is that?
2012-06-19T12:26:09 < dongs> jlink programs my flyingthing using their jflash app in ~1.5 seconds including fullerase/program on F1
2012-06-19T12:26:25 < karlp> howbig is that app?
2012-06-19T12:26:59 < dongs> before i started link time optimizing shit it was around 43k or so I think.

2012-06-19T12:27:28 < karlp> cool, that's fine
2012-06-19T12:27:33 < karlp> just wanted ballpark

2012-06-19T12:27:40 < dongs> er yesterday
2012-06-19T12:27:42 < dongs> where they had real stlink
2012-06-19T12:27:45 < dongs> and man it was pitiful
2012-06-19T12:27:58 < karlp> 32k/sec seems alright isn' tit?Ð
2012-06-19T12:28:02 < dongs> i cant imagine hwo you guys deal with "2-3k/sec" from stlink on lunix
2012-06-19T12:28:03 < karlp> that's what you said earlier?
2012-06-19T12:28:15 < dongs> Ya but I was debugging a board with F4 and it was like 350k of flash
2012-06-19T12:28:23 < dongs> and full erase took ages
2012-06-19T12:28:34 < dongs> like ~10 seconds t o fullerase, then another 10 for flash
2012-06-19T12:28:36 < karlp> yeah, zyp fixed sf4 support to get about 10k now, which is substantially better, but still much slower :)
2012-06-19T12:28:58 < karlp> does doing a full erase make the write any faster?
2012-06-19T12:29:08 < dongs> on F1 it does, on F4 it doesnt seem to be
2012-06-19T12:29:14 < dongs> in jflash F4 erase is almost instant

2012-06-19T12:51:00 <+dekar> dongs, do you know assembly macros? is there maybe a way to undefine them?
2012-06-19T12:51:12 < dongs> other than #undef?
2012-06-19T12:52:15 <+dekar> dongs, the arm header defines them like this: asm(".macro  RETURN     cond=\n\t"
2012-06-19T12:52:28 <+dekar> inline assembly
2012-06-19T12:53:44 <+dekar> and LTO refuses to compile it now since the macro has been redefined (even though it's identical all the time)
2012-06-19T13:02:07 < dongs> FUcking garbage.
2012-06-19T13:02:23 < dongs> the onyl F2 nand example in stdperiphlib sets up sometihng called 'OneNAND'....
2012-06-19T13:02:27 < dongs> which on a closer look is acutally NOR flash
2012-06-19T13:02:31 < dongs> real fucking c lever
2012-06-19T13:04:37 < dongs> stupid. onenand is fucking nand + controller + sram
2012-06-19T13:04:39 < dongs> to fake it as NOR
2012-06-19T13:04:42 < dongs> fuck.
2012-06-19T13:05:12 <+dekar> why would you do that?
2012-06-19T13:05:31 < dongs> nand flash has much higher densities
2012-06-19T13:05:41 <+dekar> sounds about as weird as using a cpld to emulate sram using dram
2012-06-19T13:05:51 < dongs> yeah, they did that too

2012-06-19T13:06:07 < dongs> its SDRAM + controller faked as sram

2012-06-19T14:31:19 < dongs> wasting it?
2012-06-19T14:31:24 < Laurenceb> slight issue being they share dma channels on F1
2012-06-19T14:31:32 < Laurenceb> guess how it deal with that?
2012-06-19T14:31:36 < Laurenceb> it fails
2012-06-19T14:31:44 < Laurenceb> if there is a conflict
2012-06-19T14:32:13 < Laurenceb> should revert to interrupt driven, but looks like they werent that smart
2012-06-19T14:32:47 < dongs> haha
2012-06-19T14:33:08 < Laurenceb> on F4 isnt not that much of an issue as the dma is more sane

2012-06-19T18:49:28 < karlp> Laurenceb: what are you failing with now? that looks like the output of running make in the stlink examples directory.
2012-06-19T18:49:41 < Laurenceb> i know
2012-06-19T18:49:41 < karlp> youdon't have two different makefiles with Makefile vs makefile or something do you?
2012-06-19T18:49:52 < Laurenceb> the RTC on my desktop had gone mad
2012-06-19T18:50:04 < Laurenceb> and gedit was getting confused about age of files
2012-06-19T18:50:10 < karlp> by default, that builds three times, once for each discovery board
2012-06-19T18:50:20 < karlp> yeah, changing clocks will royally screw up make
2012-06-19T18:50:31 < Laurenceb> fixed it now
2012-06-19T18:50:53 < karlp> when in doubt, make clean
2012-06-19T18:51:14 < jpa-> or make -B
2012-06-19T18:51:27 < jpa-> even make clean sucks if your clean rule sucks

2012-06-19T18:51:45 < karlp> yeah, that's truye.
2012-06-19T18:51:50 < karlp> huh, -B looks cool.
2012-06-19T18:52:03 < Laurenceb> interesting
2012-06-19T18:52:18 < karlp> having clean depend on anything is probably a really bad idea
2012-06-19T18:52:28 < karlp> unless you're a wizard with phoney and so on.
2012-06-19T19:06:05 < zyp> the need for having clean at all seems so stupid
2012-06-19T19:06:47 < karlp> work around for bad rules?
2012-06-19T19:07:02 < zyp> scons have a clean function that just determines the files to be cleaned from the dependency graph
2012-06-19T19:07:03 < karlp> we should all use scons right? ;)
2012-06-19T19:07:06 < karlp> hehe

2012-06-19T19:11:33 < BrainDamage> the difference between something that can break and something unbrekable, is that when the unbreakable thing breaks, it's irrecuperable
2012-06-19T19:14:18 < zyp> :p
2012-06-19T19:16:05 <+Steffanx> Thorn is jealous ?
2012-06-19T19:18:19 < karlp> cortex m0+ allows "multi drop serial wire"
2012-06-19T19:18:20 < karlp> wee
2012-06-19T19:18:56 < zyp> yeah, you just wire the swd lines in parallel
2012-06-19T19:19:05 <+Steffanx> I support drop all serial wire karlp
2012-06-19T19:19:10 <+Steffanx> Sorry, ignore me
2012-06-19T19:19:30 < zyp> which they will be if you wire them for jtag, since swd signals are on jtck and jtms
2012-06-19T19:23:50 < Thorn> have you read about target discovery in multidrop swd? the debugger has to probe for all chip IDs it knows about, and I've no idea what would happen if there're multiple identical ones on the bus
2012-06-19T19:24:47 < zyp> really?
2012-06-19T19:24:51 < zyp> well
2012-06-19T19:25:10 < zyp> I'd be surprised if it didn't support several identical (apart from serial) devices on the bus
2012-06-19T19:35:34 < Thorn> afair serial numbers play no role
2012-06-19T19:39:26 < Thorn> (and you can't use jtag even if targets support it because the bus has to be wired differently)

2012-06-19T20:09:39 < Thorn> I think it could sell really well in Japan
2012-06-19T20:10:18 <+Steffanx> Maybe you can start to sell them in Russia
2012-06-19T20:12:06 < Thorn> afaik many of those who collect this kind of things order them online directly from Japan. buying them locally is not hip enough

2012-06-19T21:37:49 < zyp> Laurenceb_, of course?
2012-06-19T21:37:54 < BrainDamage> I guess it waits until the buffer is full?
2012-06-19T21:38:03 < Laurenceb_> then how an i meant to say connect a gps receiver?
2012-06-19T21:38:05 < BrainDamage> and returns when done
2012-06-19T21:38:06 < zyp> how would it else know how many bytes you want to read?
2012-06-19T21:38:18 < Laurenceb_> just have a circular rx buffer
2012-06-19T21:38:34 < Laurenceb_> a byteinbuff function and a read function
2012-06-19T21:39:08 < BrainDamage> have a rx buffer, read in chunks of fixed size and sum to a larger buffer that gets resized dynamically, then consume the larger as needed
2012-06-19T21:39:50 < Laurenceb_> then i have lag
2012-06-19T21:39:56 < Laurenceb_> unless i use 1 byte buffer
2012-06-19T21:41:04 < BrainDamage> depending how you hate yourself, you could make a linked list of the buffer chunks to make the larger buffer which sums them
2012-06-19T21:41:05 < Laurenceb_> maybe serial driver is what i want...
2012-06-19T21:42:05 < zyp> Laurenceb_, you could register your own interrupt callback

2012-06-19T21:42:17 < Laurenceb_> ^i think that would work
2012-06-19T21:43:18 < Laurenceb_> seems to use a proper fifo buffer
2012-06-19T21:52:45 < Laurenceb_> sdAsynchronousRead looks better actually

2012-06-19T23:26:56 < blkcat> Thorn: reasonably *in*expensive, sorry haha
2012-06-19T23:27:23 < blkcat> zippe: spi would probably be fine? honestly i've never had to shop for displays before (beyond boring character lcds)
2012-06-19T23:27:41 < zippe> Yes, I see.
2012-06-19T23:27:56 < zippe> What are you going to do with it?  What frame rate are you trying to achieve?
2012-06-19T23:28:06 < Thorn> 3x2" over spi is going to be slow
2012-06-19T23:28:27 <+Steffanx> 3x2 pixels isn't that bad
2012-06-19T23:28:35 <+Steffanx> *much
2012-06-19T23:28:40 <+Steffanx> or 6x3
2012-06-19T23:28:52 < zippe> 320 x 240 @ 8-bit color is 1.8MiB
2012-06-19T23:29:17 < zippe> er, Mib
2012-06-19T23:29:47 < zippe> So each frame needs ~2MHz on your SPI bus.

2012-06-19T23:32:19 < zippe> For panels up to 16bpp you may be able to use the FSMC and DMA to auto-refresh
2012-06-19T23:33:13 < blkcat> zippe: nxp has some cortex-m3s with integrated lcd controllers, i was considering one of those perhaps
2012-06-19T23:33:57 < Thorn> in that case you need displays with an rgb interface
2012-06-19T23:34:14 < Thorn> which is most certainly not spi
2012-06-19T23:36:28 < zippe> Ya, in general a bit hard to offer specific suggestions without knowing what controller, etc.
2012-06-19T23:36:52 < blkcat> yeah. i think i have some more reading to do.
2012-06-19T23:36:54 < Thorn> England prevails

2012-06-19T23:41:20 < drgreenthumb> blkcat, just a very random suggestion here but I had some luck with http://www.newhavendisplay.com/nhd18128160tfctxi-p-4981.html ... it has it's own controller and memory, so I was able to drive the thing from a slowass 8Mhz AVR. they had some example code which worked with very minimal changes. prototyping sucks a bit though, even with that breakout board - so many wires!
2012-06-19T23:42:00 < blkcat> drgreenthumb: thanks for the tip! unfortunately i'm/we're looking for something a bit bigger with a higher resolution
2012-06-19T23:42:07 < drgreenthumb> ah
2012-06-19T23:42:10 < blkcat> i think the target is around 4" diagonal
2012-06-19T23:42:22 < drgreenthumb> ah yes those are harder to drive I believe :)
2012-06-19T23:42:34 < Thorn> not necessarily
2012-06-19T23:42:49 < drgreenthumb> yeah I guess if it has a controller it'd be similar to what I did with this little one
2012-06-19T23:42:56 < drgreenthumb> but most I've seen are RGB interface

2012-06-19T23:59:01 < blkcat> okay, let's say i need 24-bit color, somewhere in the vicinity of 24fps. something like 800x400 would be great but i could settle for less.
2012-06-19T23:59:08 < blkcat> i'd probably need a pretty beefy controller to drive that, right?
--- Day changed Wed Jun 20 2012
2012-06-20T00:00:27 < Thorn> that would be a pretty nice intermediate level fpga project
2012-06-20T00:01:41 < Thorn> 800 pixels will likely mean LVDS which arm mcus lack, also RAM for the framebuffer and hard realtime refresh logic
2012-06-20T00:02:02 < Thorn> (external RAM)
2012-06-20T00:02:03 <+izua> that's a pretty good price for 128x160x8
2012-06-20T00:02:26 < Thorn> I've seen similar ones for ~$6 on aliexpress
2012-06-20T00:02:58 < Thorn> (also, I've no idea about newhaven shipping terms)
2012-06-20T00:03:28 < blkcat> actually, i bet 12fps would cut it.
2012-06-20T00:04:12 < zippe> LVDS or MIPI
2012-06-20T00:04:43 < zippe> 24-bit color is really overdoing it
2012-06-20T00:04:57 < zippe> You would almost certainly be fine with a 16bpp panel
2012-06-20T00:05:18 < zippe> 18bpp is pretty standard for laptop displays
2012-06-20T00:06:26 < zippe> But 8x4x16bpp is still going to be tens of dollars in any quantity
2012-06-20T00:10:29 < blkcat> indeed...
2012-06-20T00:11:03 < Thorn> 1280x800 tft panel driven by a CPLD (no LVDS hardware)  with a piece cut out of a DIMM module as a framebuffer, all connected with wires and pin headers http://marsohod.org/index.php/projects/174-phframe3
2012-06-20T00:12:31 < drgreenthumb> that's pretty cool :)
2012-06-20T00:12:50 < blkcat> now that's impressive.
2012-06-20T00:13:00 < drgreenthumb> heh I was wondering if a display driver and DDR SDRAM driver would both fit on a CPLD. apparently, yes, yes it can :)
2012-06-20T00:13:22 < Thorn> these guys also made a CPU for EPM240
2012-06-20T00:13:33 < blkcat> perhaps it'd be cheaper to reuse a knockoff itouch 2g display or something...

2012-06-20T02:48:55 < zippe> And the datasheets are a bit scary.  e.g.
2012-06-20T02:48:56 < zippe> The NuMicro Mini51 series provides one channel of Universal Asynchronous Receiver/Transmitters (UART). UART performs Normal Speed UART, and support flow control function.
2012-06-20T02:49:17 < pepsi_> only one, eh?
2012-06-20T02:50:09 < pepsi_> i dont remember why i didnt like it.. i think it was mostly fear of the unknown as well.. but i seem to recall it lacking in some technical features
2012-06-20T02:50:17 < pepsi_> and one uart is a bunch of poop :P
2012-06-20T02:51:56 < zippe> The Mini51's are the very small ones; they're kinda short on timers too
2012-06-20T02:52:02 < karlp> we're using stm32 right now precisely because the avr part we had before was only a single uart.
2012-06-20T02:53:04 < pepsi_> you guys do this for hobby? work?

2012-06-20T05:08:47 < szczys> it's like they tried to simplify it with abstraction but just ended up with an entirely unrelated mess of obscurity

2012-06-20T05:14:50 < szczys> thanks
2012-06-20T05:18:27 < zippe> szczys: You are looking at the ST driver library?  It's junk
2012-06-20T05:18:34 < zippe> Have you looked at libopencm3 yet?
2012-06-20T05:18:40 < zippe> It's not bad for the things it covers.
2012-06-20T05:18:43 < dongs> st driver library >WORKS<
2012-06-20T05:18:48 < dongs> unlike libopencm3.
2012-06-20T05:18:51 < zippe> dongs: sometimes
2012-06-20T05:18:56 < dongs> no, it works out of hte box.
2012-06-20T05:18:59 < zippe> dongs: Don't try to use e.g. their USB stack
2012-06-20T05:19:13 < zippe> dongs: again, sometimes.  It also doesn't actually *do* anything
2012-06-20T05:19:31 < zippe> dongs: e.g. where is the I2C state machine?
2012-06-20T05:19:41 < zippe> dongs: where is the UART driver?
2012-06-20T05:19:57 < zippe> Where is anything resembling a coherent power management API?
2012-06-20T05:20:28 < zippe> It's not a "driver library", it's a "wrapper function library"
2012-06-20T05:20:44 < dongs> right
2012-06-20T05:20:46 < dongs> and im fine with that.
2012-06-20T05:20:55 < dongs> drivers implemented one specific way = fail
2012-06-20T05:21:02 < dongs> like look like Laurenceb bitching about chibios yesterday
2012-06-20T05:21:07 < dongs> using DMA for I2C and SPI
2012-06-20T05:21:08 < szczys> I've looked at the examples in libopencm3
2012-06-20T05:21:15 < dongs> (or some other 2 peripherals that conflict)
2012-06-20T05:21:19 < zippe> dongs: LMI got it pretty right.
2012-06-20T05:21:20 < dongs> their solution? just crash when ith appens.
2012-06-20T05:21:22 < szczys> Hey, can you shed some light on this:
2012-06-20T05:21:31 < szczys> I see where to set GPIO speed, and the speed values available
2012-06-20T05:21:39 < szczys> but what is the speed setting actually doing?
2012-06-20T05:21:47 < zippe> slew rate limiting
2012-06-20T05:21:52 < szczys> slew?
2012-06-20T05:22:06 < dongs> howe fast ir rises
2012-06-20T05:22:09 < zippe> How fast the transition from 1 to 0 or vice versa is
2012-06-20T05:22:23 < zippe> The faster the transition, the more power you use, and the more RF noise you emit
2012-06-20T05:22:38 < szczys> ah-ha
2012-06-20T05:22:43 < szczys> I see the value in slowing it down
2012-06-20T05:22:43 < dongs> cuz square waves love making harmonics
2012-06-20T05:22:58 < szczys> thanks for explaining
2012-06-20T05:22:59 < zippe> Not to mention ringing, power rail glitching, you name it
2012-06-20T05:24:35 < szczys> so I see that the low rate is 2 MHz
2012-06-20T05:24:45 < szczys> if I'm running the system clock at 48 MHz
2012-06-20T05:24:56 < szczys> and I'm switching GPIO often, does this present a problem?
2012-06-20T05:26:12 < dongs> it takes a few cycles to switch.. try doing GPIOx->BSRR = blah; GPIOx->BRR = blah; in a loop and scope it to see what the max switching speed you can get at 48mhz
2012-06-20T05:26:16 < dongs> i think it takes a few cycles per
2012-06-20T05:26:43 < dongs> or GPIOx->ODR if you wanna try toggling with one instruction
2012-06-20T05:26:58 < dongs> GPIOx->ODR ^= blah;
2012-06-20T05:27:00 < szczys> so does it hold up the next instruction
2012-06-20T05:27:10 < szczys> or does it drop GPIO changes?
2012-06-20T05:27:17 < szczys> (obviously it drops gpio changes)
2012-06-20T05:27:28 < dongs> i dunno, i never bothered to look
2012-06-20T05:28:34 < szczys> well, if I run the SPI with the lowest clock divider (2)
2012-06-20T05:28:42 < szczys> then I'm running at 24 MHz
2012-06-20T05:29:24 < dongs> well, spi toggles GPIO indepenedent of your code
2012-06-20T05:29:24 < szczys> I guess I've got to look up how many instructions it takes to pulse the clock and shift the FIFO
2012-06-20T05:29:27 < dongs> i.e. clk lines etc.
2012-06-20T05:29:29 < dongs> no
2012-06-20T05:29:31 < szczys> right
2012-06-20T05:29:39 < szczys> but the driver library says I need to set the gpio speed
2012-06-20T05:29:43 < dongs> SPI is hardware, so when you tell it to run at 24mhz, thats what it runs at.
2012-06-20T05:29:52 < dongs> yes, so obviously you set it to >= 24mhz
2012-06-20T05:29:55 < zippe> szczys: You still need to set the pad slew rate though
2012-06-20T05:29:59 < dongs> i think the choices are liek 2/50/wahtever
2012-06-20T05:30:03 < szczys> right
2012-06-20T05:30:06 < zippe> 2/10/50 IIRC
2012-06-20T05:30:14 < szczys> 2/10/50
2012-06-20T05:30:15 < szczys> yep
2012-06-20T05:30:21 < szczys> so 2 probably isn't fast enough?
2012-06-20T05:30:25 < dongs> ...
2012-06-20T05:30:29 < zippe> Dammit, I really want a version of tpl that has already been ported to an embedded environment
2012-06-20T05:30:41 < zippe> szczys: No, that will give you bad results for 24MHz SPI
2012-06-20T05:30:44 < dongs> szczys: if youre running SPI at 24mhz, it should be above that.
2012-06-20T05:30:50 < dongs> as it will be toggling clk at 24mhz.
2012-06-20T05:30:53 < szczys> okay... thanks

2012-06-20T08:43:37 < dongs> sure i am
2012-06-20T08:43:42 < dongs> i already made all the shit slow as hell
2012-06-20T08:43:42 < zippe> zyp: actually, I don't believe you can; all the timer clocks come out of the clock tree.
2012-06-20T08:43:58 < zippe> zyp: i.e. all derived from sysclk
2012-06-20T08:45:10 < zippe> zyp: You could perhaps route HSE to the RTC and use that to compare vs. a timer based off HSI
2012-06-20T08:45:45 < dongs> why hasnt anyone properly done this :(
2012-06-20T08:47:15 < dongs> are you saying i shouldnt have any extra bytes at start of fsmc read?
2012-06-20T08:57:51 < zyp> zippe, you can choose different clock sources for some timers, just for this purpose
2012-06-20T08:58:14 < zyp> it's documented in the reference manual, but I don't have time to look it up now, heading out
2012-06-20T09:08:21 < zippe> Sort of. You can use timer 5/11 input capture to measure the HSI and HSE clocks, but not actually clock them with it.
2012-06-20T09:08:35 < dongs> neither available on _MD
2012-06-20T09:10:00 < zippe> sorry, that's F4 only.  Looking at F1 now
2012-06-20T09:12:46 < zippe> Yeah, so your best bet would be to configure the RTC to run off HSE/128 and then compare the RTC clock rate against a timer
2012-06-20T09:13:32 < dongs> F1 can take up to 24mhz xtal right?
2012-06-20T09:13:40 < dongs> then they bumped that to 25 in F2/F4?
2012-06-20T09:13:44 < zippe> Yes, believe so
2012-06-20T09:13:53 < zippe> 25 so they could do 100Mbps ethernet
2012-06-20T09:14:30 < zippe> oh wait, no
2012-06-20T09:14:34 < zippe> They have a separate ethernet osc
2012-06-20T09:14:37 < zippe> wacky
2012-06-20T09:14:59 < dongs> dont you need a external ethernet phy anyway
2012-06-20T09:15:06 < dongs> which will surely need its own xtal

2012-06-20T09:30:39 < dongs> its HY27UF(08/16)2G2B (1st google hit = datasheet off hynix.co.kr but fucking google rapeifies the links so i cant paste it
2012-06-20T09:30:57 < zippe> Ok, so probably 2112B pages?
2012-06-20T09:31:00 < dongs> yes
2012-06-20T09:31:05 < zippe> What wrote the NAND?
2012-06-20T09:31:13 < dongs> not me
2012-06-20T09:31:18 < dongs> i just want to read it.
2012-06-20T09:31:21 < dongs> but, most likely, lunix
2012-06-20T09:31:27 < dongs> as I saw bits of boot=/ lol stuff in there
2012-06-20T09:31:29 < zippe> Ok, so quite possibly YAFFS?
2012-06-20T09:31:31 < dongs> while trying random addresses
2012-06-20T09:31:53 < dongs> right, but my problem is i cant even get what looks like contigious data out of it
2012-06-20T09:32:01 < dongs> table 3, address cycle map for x8
2012-06-20T09:32:28 < dongs> http://bcas.tv/paste/results/WryfJ423.html
2012-06-20T09:32:34 < dongs> this should trnslate to physical address right?
2012-06-20T09:32:42 < dongs> so theoretically i can do addr=0, addr=1 and it will return shit shifted by 1?
2012-06-20T09:33:01 < dongs> another datasheet of similar shit talks about "column address" and "row address"
2012-06-20T09:33:15 < zippe> Not sure what you're talking about here
2012-06-20T09:33:28 < dongs> read page command.
2012-06-20T09:33:33 < zippe> sorry; assuming you're trying to construct a raw NAND page read command
2012-06-20T09:33:36 < dongs> its 00 | addr1 2 3 4 5 | 30
2012-06-20T09:33:37 < dongs> yes
2012-06-20T09:34:08 < dongs> i dont see how 1st/2nd cycle address a 2k page though
2012-06-20T09:34:14 < dongs> since they talk about 12 bits (A0..A11)
2012-06-20T09:34:16 < dongs> thats 4K...
2012-06-20T09:35:32 < dongs> i was kind of hoping at least all flashes would have similar fucking programming interface...
2012-06-20T09:35:42 < dongs> but apparently its a worse clusterfuck than desktop lunix
2012-06-20T09:36:11 < zippe> They're all very similar
2012-06-20T09:36:24 < zippe> But none designed for any sort of forward expansion, much like win19/win32
2012-06-20T09:38:21 < zippe> Ok, so looking back at some old code
2012-06-20T09:38:32 < zippe> "column address" is a byte offset within the page
2012-06-20T09:38:36 < dongs> right
2012-06-20T09:38:40 < dongs> but why is it 12bit
2012-06-20T09:38:42 < zippe> It allows the readout from the page buffer to start offset into the page
2012-06-20T09:39:02 < zippe> because the page is 2112 bytes long
2012-06-20T09:39:18 < dongs> you mean.. including ECC shit
2012-06-20T09:39:20 < zippe> yes
2012-06-20T09:39:31 < dongs> so i could just leave the shit as 0 if I dont care about offset.
2012-06-20T09:39:32 < zippe> Though in fact you'll find that for 4K page nand, it's 13 bits.
2012-06-20T09:39:34 < zippe> Yes.
2012-06-20T09:39:45 < zippe> If you're just stripping it, you want column 0
2012-06-20T09:41:19 < dongs> so then i just give them address in multiples of 2048
2012-06-20T09:41:23 < dongs> 0, 2048, 4096,, etc
2012-06-20T09:41:27 < dongs> and that works?
2012-06-20T09:41:46 < dongs> or wait no...
2012-06-20T09:41:51 < zippe> Assuming you have your shifts correct
2012-06-20T09:42:19 < zippe> I haven't looked at how the F4 fsmc generates the NAND addresses
2012-06-20T09:42:46 < zippe> It will save you a lot of grief if you separate "column" and "page" and just accept that the page address is packed weirdly
2012-06-20T09:42:54 < dongs> right
2012-06-20T09:42:58 < dongs> just ognna zero column
2012-06-20T09:43:03 < dongs> and i guess pages are shifted up
2012-06-20T09:43:18 < zippe> Right
2012-06-20T09:43:50 < zippe> Here's a snip of some old code that might help
2012-06-20T09:44:13 < zippe> static void
2012-06-20T09:44:13 < zippe> fmcSetPageAddress(UInt32 page, UInt16 offset)
2012-06-20T09:44:13 < zippe> {
2012-06-20T09:44:13 < zippe>         UInt32  columnAddress;
2012-06-20T09:44:13 < zippe>         
2012-06-20T09:44:14 < zippe>         setFMCANUM(4);
2012-06-20T09:44:15 < zippe>         /* allow transfers to start offset from the base of the page */
2012-06-20T09:44:15 < zippe>         columnAddress = offset & 0x1fff;
2012-06-20T09:44:16 < zippe>         setFMCADDR0(((page & 0xffffUL) << 16) | columnAddress);
2012-06-20T09:44:17 < zippe>         setFMCADDR1(page >> 16);

2012-06-20T11:30:30 < cjbaird> "buffer += (int)offset;" would make the compile think you want pointer arthmetic with (4-byte wide) ints, then cast back to char* .. (char)offset keeps it in bytes.

2012-06-20T13:32:04 <+dekar> cjbaird, I like the NOPs :)
2012-06-20T13:34:07 < cjbaird> That's the code from the other night, showing the difference that pointer crafting makes to GCC output..
2012-06-20T13:40:00 <+dekar> hows the battery life for that lemote?
2012-06-20T13:41:17 < cjbaird> It's just 3 cells, so about 90 minutes.
2012-06-20T13:41:40 <+dekar> that sucks, I guess I'd rather get an atom them
2012-06-20T13:42:12 <+dekar> I mean it doesn't seem to be too cheap either, $450 on amazon :/
2012-06-20T13:44:20 < dongs> lol, lemote
2012-06-20T13:44:37 < dongs> it has a color display?
2012-06-20T13:44:38 < cjbaird> I paid AU$500 about 2 ?3 years ago.. As I don't buy a new netbook whenever the next model comes out, I decided I'd get someone a little more distinctive. :) (MIPS!)
2012-06-20T13:44:38 < dongs> what hte fuck
2012-06-20T13:44:56 < dongs> i expectd it to have amber monochrome or something
2012-06-20T13:45:50 <+dekar> mips is cool, but it should match the battery life of a tablet at least
2012-06-20T13:45:53 <+dekar> like 10-12h
2012-06-20T13:46:33 < cjbaird> Although the next model of Lemote looks neat: 4 core @ 1.2GHz, at the same power usage.

2012-06-20T13:47:44 <+dekar> though I'd guess I'd rather have an x86er or arm for the better software support
2012-06-20T13:48:21 <+dekar> gnu radio barely performs on ARM (using ARM neon) and completely falls back to all software without vectorization support for other architectures
2012-06-20T13:48:33 < cjbaird> The Loongson has quite a few parallel-math instruction extensions..
2012-06-20T13:48:44 <+dekar> yeah but software has to support those
2012-06-20T13:48:55 <+dekar> I don't feel like adding them to gnu radio
2012-06-20T13:49:14 <+dekar> gcc auto-vectorization only gets you so far

2012-06-20T14:00:05 < BrainDamage> you got a dvb key too? what are you decoding?
2012-06-20T14:00:28 < dongs> wat
2012-06-20T14:01:05 < BrainDamage> they found a debug mode in a dvb key usb interface chip that allows you to extract IQ raw samples
2012-06-20T14:01:22 < BrainDamage> this allows you to do baseband processing yourself, on your pc
2012-06-20T14:01:33 < BrainDamage> and use the dongle as simple downconverter + adc
2012-06-20T14:02:09 < BrainDamage> so you can get "any" signal which has bandwith of ~1MHz and range of 50 to 1.9GHz with some gap around 1.2GHz
2012-06-20T14:02:30 < BrainDamage> gnuradio is a lib that had a collection of many decoders, etc
2012-06-20T14:03:34 < BrainDamage> some people decoded gps, gsm, etc

2012-06-20T14:22:50 <+dekar> at least people over at ##rtlsdr said so
2012-06-20T14:22:55 < BrainDamage> it's an hw limitation
2012-06-20T14:23:02 <+dekar> idk, didn't dig into it
2012-06-20T14:23:11 <+dekar> but multiple people reported it to work
2012-06-20T14:23:34 <+dekar> the problem was the PLL not locking, wasn't it?
2012-06-20T14:23:53 < BrainDamage> yes, because it was never designed to lock in that range itfp
2012-06-20T14:24:06 <+dekar> BrainDamage, also my RTL-SDR goes up to 2.2ghz
2012-06-20T14:24:14 < BrainDamage> afaik some non e4000 tuners allow you to tune in that range
2012-06-20T14:24:24 < BrainDamage> so does mine
2012-06-20T14:24:49 <+izua> dekar: so did you dug into digital modes?
2012-06-20T14:25:00 <+izua> can you actually listen to them with your sdr?
2012-06-20T14:25:04 < BrainDamage> but also afaik, those tuners use a sep mixer and input pin for those modes, which is grounded in the dvb key
2012-06-20T14:25:16 < BrainDamage> so you'd have to resolder it, and it's qfn

2012-06-20T16:39:16 < zyp> with the current abundance of usb capable microcontrollers, dedicated usb-serial chips are kind of obsolete
2012-06-20T16:39:26 < dongs> hardly
2012-06-20T16:39:37 < dongs> i for one dont feel like figuring out usb/cdc shit and making bootloaders and  crap
2012-06-20T16:39:53 < dongs> though I guess if there's DFU thts  another story.
2012-06-20T16:40:38 < Thorn> I almost agree, now if only ftdi had an interrupt capability
2012-06-20T16:41:39 < zyp> adding software is cheaper than adding another chip, both if you are considering BOM and board area
2012-06-20T16:42:51 < BrainDamage> unless the hw is already there
2012-06-20T16:42:58 < BrainDamage> and you want to extend functionality
2012-06-20T16:43:37 < zyp> though, I guess you can argue that you have to have a fair production volume before the cost of the chips are larger than the time invested in getting usb working
2012-06-20T16:45:37 < Laurenceb> cp2102 is nice
2012-06-20T16:45:47 < Laurenceb> or just usb-cdc on an stm
2012-06-20T16:46:28 < dongs> zyp, indeed. cp2102 for 70c or whatever the fuck makes much more sense than idiot users trashing the bootloader.
2012-06-20T16:46:51 < dongs> i mean people are having trouble with usb>serial bootloader, holy fuck imagine the support idiocy if there was no failsafe way to go back.
2012-06-20T16:47:10 < zyp> trashing bootloader how?
2012-06-20T16:47:30 < dongs> zyp, i get about one idiot every other week who can't figure out how to use fucking flash loader demonstrator.
2012-06-20T16:47:38 < dongs> or claiming they "fried" boards by reflashing them
2012-06-20T16:47:47 < dongs> and this is with bootloader in hardware.
2012-06-20T16:47:54 < zyp> if the bootloader doesn't allow overwriting itself, it can't trash itself
2012-06-20T16:48:00 < dongs> i dunno, pulling usb half-write, or uploading some avr .hex file or whatever.
2012-06-20T16:48:14 < dongs> zyp, when there's enough idiots, they will find a way
2012-06-20T16:48:20 < zyp> and if people still manage to overwrite the bootloader, they have the means to write it back

2012-06-20T16:49:29 < Laurenceb> so it cant be overwritten
2012-06-20T16:49:34 < dongs> right...
2012-06-20T16:49:35 < zyp> it's in a locked area of flash
2012-06-20T16:49:40 < Laurenceb> ok
2012-06-20T16:49:44 < Laurenceb> oh but its serial
2012-06-20T16:49:46 < Laurenceb> doh
2012-06-20T16:49:53 < dongs> on F2/F4 there's USB too.
2012-06-20T16:49:55 < zyp> oh, and the one in F2/F4 supports usb as well

2012-06-20T16:49:59 < zyp> :p

2012-06-20T16:50:12 < zyp> only OTG_FS though, not HS
2012-06-20T16:50:18 < Laurenceb> so he needs usb-serial to be noobproof
2012-06-20T16:50:51 < zyp> it's just moving the problem to another chip
2012-06-20T16:50:58 < Laurenceb> no
2012-06-20T16:51:03 < zyp> sure it is
2012-06-20T16:51:05 < Laurenceb> cuz you cant brick a cp2102
2012-06-20T16:51:22 < zyp> sure I can
2012-06-20T16:51:23 < Thorn> okay now I have 5 boards running at the same time but only one debugger
2012-06-20T16:51:39 < Thorn> well, 3 stm32 boards
2012-06-20T16:51:41 < zyp> Laurenceb, how much heat do you think it'll handle :p
2012-06-20T16:51:45 < Laurenceb> lol
2012-06-20T16:52:59 < Thorn> I need to try and do a jtag chain from 3 boards
2012-06-20T16:53:07 < zyp> I don't see why a bootloader that doesn't allow overwriting itself is any less noobproof than unwritable hardware
2012-06-20T16:53:41 < zyp> if you argue that the bootloader can be erased by other means, I argue that another chip can be physically damaged
2012-06-20T16:53:43 < Laurenceb> but stm32 doesnt have flashlockbits does it?
2012-06-20T16:53:47 < Laurenceb> unlike avr
2012-06-20T16:53:54 < dongs> it does
2012-06-20T16:53:58 < dongs> you can protect pages
2012-06-20T16:54:01 < Laurenceb> permanent?
2012-06-20T16:54:07 < dongs> until serial bootloader, sure
2012-06-20T16:54:13 < dongs> i dont think you can set it outside bootloader
2012-06-20T16:54:18 < Laurenceb> oh ok
2012-06-20T16:54:35 < Laurenceb> you could protect the usb bootload flash then
2012-06-20T16:54:45 < zyp> I'm pretty sure they can be set via jtag as well
2012-06-20T16:55:47 < Laurenceb> ok, problem sorted
2012-06-20T16:56:00 < dongs> people will still fuck something up.
2012-06-20T16:56:30 < Laurenceb> hmm... fat32 file system that mounts the onboard flash as mass storage
2012-06-20T16:56:37 < BrainDamage> ass storage
2012-06-20T16:56:38 < Laurenceb> then you stick a .bin on there
2012-06-20T16:56:50 < dongs> ya that sounds like hueg bloatware
2012-06-20T16:56:54 < Laurenceb> reboot and the bootloader detects the .bin and uses it to write the flash
2012-06-20T16:57:04 < Laurenceb> it would be very noob friendly
2012-06-20T16:57:16 < BrainDamage> there's many fw update systems that do that actually
2012-06-20T16:57:25 < zyp> mbed for instance
2012-06-20T16:57:26 < BrainDamage> read file from usb stick
2012-06-20T16:57:41 < Laurenceb> thats usb otg surely?
2012-06-20T16:57:55 < Laurenceb> i guess usb dfu is the way to go
2012-06-20T16:58:10 < Laurenceb> im going to use mass sotrage on my logger
2012-06-20T16:58:15 < Laurenceb> but that has an sd card
2012-06-20T16:58:17 < zyp> I looked at the dfu specs once
2012-06-20T16:58:30 < Laurenceb> are they horrific?
2012-06-20T16:58:40 < zyp> nah, they are pretty simple
2012-06-20T16:58:46 < Laurenceb> ok
2012-06-20T16:58:49 < dongs> cant be much worse than this fucking nand flash trash

2012-06-20T16:59:15 < Laurenceb> why does my phone get ">pers"
2012-06-20T16:59:22 < Laurenceb> texts
2012-06-20T16:59:57 < zyp> the thing with the dfu specs is that they are written so that any dfu loader software could be used with any dfu target
2012-06-20T17:00:03 < Laurenceb> full of undisplayed characters
2012-06-20T17:00:26 < zyp> because it's just transferring a binary image
2012-06-20T17:00:42 < karlp> what sort of limitations are a problem?
2012-06-20T17:00:53 < karlp> dfu sounds like a pretty good idea to have burnt into rom
2012-06-20T17:00:55 < zyp> the only requirement is that the binary file that's transferred ends with a dfu header
2012-06-20T17:01:34 < zyp> but the format is otherwise unspecified, so it could be whatever your bootloader on the dfu target expects

2012-06-20T17:02:21 < zyp> karlp, the main limitation I noticed was the linear transfer of the files
2012-06-20T17:02:45 < Laurenceb> arg no 470nF caps :(
2012-06-20T17:02:49 < karlp> just meaning you always had to load the entire image, or what?
2012-06-20T17:02:50 < zyp> I was hoping that the bootloader could request specific ranges of the file
2012-06-20T17:02:54 < karlp> right.
2012-06-20T17:02:57 < Laurenceb> why is there no capacitor cornershop :(

2012-06-20T17:03:19 < dongs> yeah if you wanted some throughhole 470nf caps
2012-06-20T17:03:25 < Laurenceb> lmao
2012-06-20T17:03:32 < zyp> dongs, you didn't look hard enough
2012-06-20T17:03:34 < karlp> but I guess that prevents you from using a certain block of flash as eeprom emul or something too doesn't it
2012-06-20T17:03:55 < zyp> karlp, you don't have to load it continously into flash

2012-06-20T17:16:30 < dongs> and you need to sign it
2012-06-20T17:16:31 <+dekar> windows almost always looks at the VID/PID
2012-06-20T17:16:33 < dongs> for 64bit.
2012-06-20T17:16:35 < zyp> no, windows needs you to install a driver for CDC
2012-06-20T17:16:54 < dongs> zyp, openpilot also uses hid for thier shit
2012-06-20T17:16:55 < dongs> telemetry too
2012-06-20T17:17:09 <+dekar> and HID just works in a really convenient way
2012-06-20T17:17:31 < zyp> the problem is not with CDC, the problem is that windows don't handle standard classes in a sane way

2012-06-20T17:17:40 < dongs> no it isnt
2012-06-20T17:17:49 <+dekar> USB on linux sucks as well though, by default on most distributions you can't access usb devices
2012-06-20T17:18:03 <+dekar> you need to install UDEV rules and the like to change permissions
2012-06-20T17:18:08 < dongs> haha distributions.
2012-06-20T17:18:49 <+dekar> so we only support Debian and Ubuntu right now
2012-06-20T17:19:00 <+dekar> offering a .deb doing the job
2012-06-20T17:19:06 < zyp> dekar, on OS X you have access to all usb devices by default
2012-06-20T17:19:13 <+dekar> zyp, yeah I like that
2012-06-20T17:19:14 < Tectu> dekar, USB just sucks because lack of configuration
2012-06-20T17:19:25 < dongs> why bother supporitng lunix at all
2012-06-20T17:19:35 < dongs> does it  even make sense commercially
2012-06-20T17:19:49 <+dekar> zyp, not for all though, if there is a standard driver loaded already, then you can't open the device unless you unload the kernel driver
2012-06-20T17:19:55 < zyp> but yeah, I don't understand why ubuntu and stuff like that doesn't add users to a group allowing access to all usb devices by default
2012-06-20T17:20:05 < zyp> dekar, that's obvious
2012-06-20T17:20:08 < dongs> why is this even an issue in the first place
2012-06-20T17:20:18 < dongs> user groups? a ccesses? usb devices? in 2012? what the fuck.
2012-06-20T17:20:34 <+dekar> dongs, we have a bunch of customers who use linux, probably around 5-10%

2012-06-20T17:21:54 < BrainDamage> I mean @ winusb
2012-06-20T17:22:00 < dongs> BrainDamage: i'd take winusb limitations over the pathetic opensores trash that is libusb
2012-06-20T17:22:08 < dongs> (there arent any btw)
2012-06-20T17:22:22 < dongs> but libusb installing itself as filter driver on top of EVERY usb device is FUCKING IDIOTIC
2012-06-20T17:22:39 < karlp> yes yes, we all love and hate all the various hacks around usb.
2012-06-20T17:22:45 < zyp> dongs, can you do isochronous shit with winusb?
2012-06-20T17:22:50 < dongs> of course
2012-06-20T17:22:59 < dongs> it does control/bulk/iso
2012-06-20T17:23:02 < dongs> why the fuck wouldnt it?
2012-06-20T17:23:10 < Thorn> winusb?
2012-06-20T17:23:15 < Thorn> does iso?
2012-06-20T17:23:18 <+dekar> I stopped using LibUSB when it somehow didn't work for HID devices plugged into USB3 ports
2012-06-20T17:23:19 < zyp> hmm
2012-06-20T17:23:34 < zyp> I checked, winusb doesn't support isochronous transfers
2012-06-20T17:23:59 < dongs> oh, maybe it doesnt. who teh fuck cares. iso on usb sucks anyway. shrug.
2012-06-20T17:24:01 < zyp> also doesn't support having several applications accessing one device at the same time
2012-06-20T17:24:02 < Tectu> dekar, afaik easiest way is to write up the USB driver module yourself ^^
2012-06-20T17:24:14 < zyp> so, there's two limitations for you
2012-06-20T17:24:15 < Tectu> or use abstractions like ttyUSB or ttyACM
2012-06-20T17:24:30 < dongs> two? where's the first one
2012-06-20T17:24:39 < dongs> almost nothing uses iso and if it does, it can also do bulk 95% of the time
2012-06-20T17:24:42 <+dekar> Tectu, I started to write my own abstraction layer using native OS apis
2012-06-20T17:24:51 < Tectu> dekar, wtf?
2012-06-20T17:24:55 < Tectu> dekar, can you tell me more?
2012-06-20T17:24:58 <+dekar> but then hidapi fixed some bugs and I switched to that
2012-06-20T17:25:09 < dongs> and if you *really* must have iso, cypress cyusb DOES support it.
2012-06-20T17:25:09 < zyp> dekar, like reinventing libusb? :p
2012-06-20T17:25:26 < dongs> and its a proper driver not some fucking opensores filterdriverhack
2012-06-20T17:25:29 <+dekar> zyp, HID only
2012-06-20T17:25:29 < Thorn> how else would you do audio over usb, other than isochronous?
2012-06-20T17:25:32 <+dekar> Tectu, https://github.com/EliasOenal/hideous
2012-06-20T17:25:57 < BrainDamage> I'd be really curious about dongs being submitted to a double blind test about "opensores" libs
2012-06-20T17:26:09 < BrainDamage> like give him 2 apis with license stripped and let him judge the quality
2012-06-20T17:26:10 <+dekar> lol
2012-06-20T17:26:25 < dongs> BrainDamage: I could spot opensores API a mile away.
2012-06-20T17:26:37 < BrainDamage> yes, that's what I'd love to verify
2012-06-20T17:26:40 < dongs> it would be all_lower_case, with nonsensical_register_names and retarded shit that makes no sense.
2012-06-20T17:27:02 < Tectu> dekar, I am not quite sure here, but at least archlinux dosen't use libusb anymore
2012-06-20T17:27:09 < Tectu> because of not supported anymore
2012-06-20T17:27:10 <+dekar> Tectu, it was a rather useless exercise, but I still think HIDeous is an epic name for an HID lib
2012-06-20T17:27:12 < Tectu> they use libusbx now
2012-06-20T17:27:25 < Tectu> yeah, the name is epic indeed
2012-06-20T17:27:25 < zyp> dekar, ha, I like it
2012-06-20T17:27:45 < Tectu> dekar, libusbx shall be far better, but you might as BrainDamage, maybe he knows more
2012-06-20T17:27:49 < zyp> hmm, never heard of libusbx
2012-06-20T17:28:30 < Tectu> zyp, libusb got somehow dropped / not activly developed anymore
2012-06-20T17:28:45 < Tectu> so someone made libusbx    http://libusbx.org/
2012-06-20T17:28:58 < zyp> yeah, I'm reading there now
2012-06-20T17:29:05 < karlp> so. anyone got any experience with canopen?
2012-06-20T17:29:10 < karlp> love/hate or other?
2012-06-20T17:29:59 < Tectu> canopen?
2012-06-20T17:30:01 < zyp> that's one of the higher layer can protocols?
2012-06-20T17:30:12 < Tectu> is that some japan robot which opens cans for you?
2012-06-20T17:30:20 < Tectu> ah, CAN -.-
2012-06-20T17:30:36 <+dekar> / hideous is a library for "driverless" usb communication.

2012-06-20T17:31:07 < Tectu> zyp, so what do you think of libusbx?
2012-06-20T17:31:51 < zyp> well, it's a fork of libusb
2012-06-20T17:32:04 < Tectu> thank you.

2012-06-20T17:32:29 < dongs> at least winusb finally paid $100 to get their 64bit windows drivers signed.
2012-06-20T17:32:32 < dongs> took them about 5 years

2012-06-20T17:34:35 < zyp> «it provides a drop-in replacement for existing libusb based code»
2012-06-20T17:35:16 < dongs> dekar, it works great. i've got a bunch of tv/usb related shits that use winusb, the driver is just part of the app, and installing it is just inf + winusb installer from msft.
2012-06-20T17:36:07 < Tectu> what is msft
2012-06-20T17:36:17 < dongs> ...
2012-06-20T17:36:20 < karlp> hehe
2012-06-20T17:36:34 < zyp> dongs, i.e. just like using libusb with the winusb backend
2012-06-20T17:36:55 < dongs> zyp, without the fucking aids.
2012-06-20T17:38:24 < dongs> winusb already *works* why would i need an opensores abstration fail on top of something that already works?

2012-06-20T17:39:44 < dongs> Thorn: oh, i meant libusb
2012-06-20T17:39:56 < zyp> oh, last year
2012-06-20T17:41:02 < zyp> the project I worked on before I started working at STE included some third party components in binary form that would only work with MSVC
2012-06-20T17:41:25 < dongs> i wish all closedsource shit would do that
2012-06-20T17:41:33 < dongs> because  microsoft compiler is by far the best one out there.

2012-06-20T17:41:52 < dongs> i fiigured someone would say that.
2012-06-20T17:41:56 < zyp> I had to waste a few hours to remove C99 stuff from the module I wrote earlier, so it would build with MSVC, because C99 support in MSVC is fucking broken

2012-06-20T17:42:52 < dongs> whats next, you'll tell me  youre using boost?
2012-06-20T17:43:20 < Thorn> of course. std::map<boost::tuple> works even in msvc2010
2012-06-20T17:44:02 <+dekar> I am glad minGW is an option on windows
2012-06-20T17:44:06 < zyp> when did STL get a tuple template?

2012-06-20T17:44:34 < zyp> right
2012-06-20T17:44:55 < Thorn> they stole it (and everything else) from boost, of course
2012-06-20T17:44:55 < zyp> so why do you expect MSVC 2010 to support it?

2012-06-20T20:32:03 < zyp> the store I visited today had the VL, F4 and L1 ones, but not the F0 one, are there more?
2012-06-20T20:33:01 <+Steffanx> That's all afaik
2012-06-20T20:33:26 < zyp> oh, and they also had an stm8-one, but I'm not interested in that
2012-06-20T20:34:30 < BrainDamage> there's also W boards
2012-06-20T20:34:34 < BrainDamage> but they are not discovery
2012-06-20T20:34:47 < zyp> so, how's st-link v1 compared to v2 from a user perspective? is it pretty much equivalent, or a pain to deal with?
2012-06-20T20:34:53 < BrainDamage> AWFUL
2012-06-20T20:35:03 < zyp> how so?
2012-06-20T20:35:14 <+Steffanx> Crappy mass storage implementation .. ?
2012-06-20T20:35:37 < zyp> but how does that matter from a user perspective?
2012-06-20T20:35:44 <+Steffanx> Which you need a codeless kext for on os x
2012-06-20T20:35:49 < BrainDamage> sometimes not working, you need to add workarounds, etc
2012-06-20T20:35:51 < zyp> ah, right
2012-06-20T20:36:01 < BrainDamage> v2 is reliable
2012-06-20T20:36:26 < BrainDamage> also has some extensions to the debug protocol, that the open obsessive-compulsive disorder guys apparently put in
2012-06-20T20:36:41 < zyp> then I'll probably pass on the VL board, and pick up a L1 board
2012-06-20T20:36:54 < zyp> and a F0 board, should I come across one
2012-06-20T20:37:05 < BrainDamage> my personal reccomendation is L1 and F4
2012-06-20T20:37:24 < zyp> I already have two F4 boards
2012-06-20T20:37:26 < BrainDamage> as in, they are the most "different"
2012-06-20T20:38:36 < zyp> I'm thinking about making some setup for automated testing on different platforms
2012-06-20T20:39:49 < zyp> oh, and to me, L1 seems to be more similar to F4 than to F1
2012-06-20T20:40:20 < BrainDamage> really? with all the powersaving features?
2012-06-20T20:40:30 < BrainDamage> or do you mean stuff like DMA arch  etc?
2012-06-20T20:41:06 < BrainDamage> ( unrelated, but I'd love a L0 chip series, chip and extremely low power )
2012-06-20T20:41:19 < zyp> I haven't really looked much at L1, so I might be wrong, but as far as I've seen, L1 seems to follow the same register layout for the peripherals as F4 has
2012-06-20T20:41:47 < zyp> yeah, I've already predicted a future L0

2012-06-20T20:47:53 < karlp> some presentation or other
2012-06-20T20:48:18 < karlp> I agree with zyp, L1 periphs are more like f4 than f1.
2012-06-20T20:49:00 < karlp> zyp: I use a VL /stlinkv1) at home all the time, it's fine under linux.
2012-06-20T20:49:16 < karlp> you just use a quirks file thingy to tell the kernel never to ever try and use it as a disk.
2012-06-20T20:49:39 < karlp> until someone adds SWV/SWO support, they're basically the same
2012-06-20T20:50:03 < karlp> (I did update the stlink firmware with st's stlink tool)
2012-06-20T20:50:35 < zyp> oh, you can flash v2 firmware onto it?
2012-06-20T20:50:37 < karlp> the L1 board is cool, but it doesn't plug into a small breadboard, you need a long one. (if that matters)
2012-06-20T20:50:43 < karlp> no, but there was an updated v1 firmware
2012-06-20T20:50:46 < karlp> which made it more reliable
2012-06-20T20:50:49 < zyp> ah
2012-06-20T20:51:02 < karlp> though dongs said he attached a debugger to the stlink tool
2012-06-20T20:51:09 < karlp> and convinced it to flash the v2 firmware somehow
2012-06-20T20:51:10 < BrainDamage> the L0 doesn't

2012-06-20T20:51:14 < BrainDamage> F0
2012-06-20T20:51:19 < zyp> hmm, I guess it could be possible to port blackmagic to it as well
2012-06-20T20:51:22 < BrainDamage> unless you remove  the strip at bottom
2012-06-20T20:51:33 < karlp> F0 has no bottom strip I thought from the pictures
2012-06-20T20:51:39 < zyp> if it's not locked
2012-06-20T20:51:44 < BrainDamage> F1
2012-06-20T20:51:45 < karlp> VL board plugs into a breadboard if youð're careful with how it overhangs the end.
2012-06-20T20:51:56 < BrainDamage> yeah, the VL
2012-06-20T20:52:01 < karlp> I havemine plugged in at home, witha  small breadboard on each side.
2012-06-20T20:52:07 < karlp> F0 looks nicer, without that bottom row
2012-06-20T20:52:26 <+Steffanx> isn't there already a stlink port zyp ?
2012-06-20T20:52:37 < zyp> hmm, might be
2012-06-20T20:52:43 < karlp> zyp: yeah, people have flashed versaloon onto it, so I'm sure bmp could be flashed too if you really wanted to.

2012-06-20T20:53:00 < zyp> ah, right
2012-06-20T20:53:37 <+Steffanx> It would be more interesting to be able to use the official bootloader
2012-06-20T20:54:02 <+Steffanx> So you get always get back to the original fw ( without extra wires)
2012-06-20T20:54:43 < karlp> what?
2012-06-20T20:55:10 <+Steffanx> stlink-bootloader => load other firmware ?
2012-06-20T20:55:36 < zyp> reverting to st-link doesn't sound very interesting after replacing it with something better
2012-06-20T20:55:49 <+Steffanx> Mwah, you still need other programmer
2012-06-20T20:56:23 < zyp> sure, I've lost count of how many I've got now
2012-06-20T20:56:34 < BrainDamage> when you have 2 discovery boards, you can use one to flash the other

2012-06-20T21:00:33 <+dekar> I am actually kinda annoyed by versaloon, they had support in upstream openOCD and they broke compatibility with firmware updates
2012-06-20T21:00:44 < zyp> never tried versaloon, but blackmagic beats stlink by far

2012-06-20T21:01:16 < karlp> you mean texane/stlink right?
2012-06-20T21:01:17 < FUZxxl> Is there any library ready to use for this thing?
2012-06-20T21:01:20 < FUZxxl> karlp: yeah
2012-06-20T21:01:32 < FUZxxl> The library shipped with stlink doesn't really work
2012-06-20T21:01:38 <+Steffanx> Not?
2012-06-20T21:01:41 < karlp> I mean, there's no particular reason that BMP should be any better than any other tool that properly uses the stlink hardware?

2012-06-20T21:09:03 < zyp> they don't have anything to do with st-link, and would be better off as a seperate repo
2012-06-20T21:09:08 <+Steffanx> There is experimental support Thorn
2012-06-20T21:09:14 < FUZxxl> I don't really understand all of the code in that lib; I decided to have a look at the spec and do that on my own.

2012-06-20T21:09:25 <+Steffanx> Thorn : https://github.com/gsmcmullin/magictpa
2012-06-20T21:09:41 < zyp> Steffanx, did you try it?
2012-06-20T21:09:45 < FUZxxl> When I compile code, some data might be placed in the .data section.
2012-06-20T21:09:47 <+Steffanx> Not yet
2012-06-20T21:10:04 < FUZxxl> If I flash that onto the chip, the data section gets placed into the ROM.
2012-06-20T21:10:13 < FUZxxl> I probably need to copy it into the RAM.
2012-06-20T21:10:16 <+Steffanx> I have the plugin installed, but actually forgot about it. Until now :)

2012-06-20T21:10:52 < zyp> you are completely right
2012-06-20T21:11:04 < FUZxxl> zyp: What I think I need to do is:
2012-06-20T21:11:19 < FUZxxl> * let the linker load the section into the ROM
2012-06-20T21:11:20 < zyp> .data is stored in flash, and then it have to be copied to ram
2012-06-20T21:11:28 < FUZxxl> * my startup code moves it into the RAM
2012-06-20T21:11:46 < zyp> yes
2012-06-20T21:11:52 < FUZxxl> How can I tell GNU ld that all references to .data should be made relative to the effective address after copying?
2012-06-20T21:12:12 < zyp> seperate LMA and VMA

2012-06-20T21:21:26 < zyp> none of course
2012-06-20T21:22:18 < zyp> the hardware will handle pushing of caller-save registers for you, so you don't have to worry about clobbering them
2012-06-20T21:22:22 < FUZxxl> okay

2012-06-20T21:25:21 < zyp> Thorn, the argument is encoded into the opcode but ignored by the cpu, so if you need it you'll have to check the old value of pc to find the opcode, then extract the value from the opcode yourself

2012-06-20T21:30:37 < zyp> dekar, so they essentially changed the mnemonic

2012-06-20T21:32:21 <+dekar> yet it might be confusing people
2012-06-20T21:32:33 < zyp> I guess they at some point had two similar instructions in arm/thumb named swi and svc, so when it got unified they changed the swi one to svc
2012-06-20T21:32:51 < zyp> or something like that
2012-06-20T21:32:52 <+dekar> but SWI was the original one

2012-06-20T21:37:52 <+dekar> imagine people using an old proprietary compiler they bought like 10 years ago
2012-06-20T21:38:21 < Thorn> if you're using dataflash for datalogging, how do you keep track of where to write the next record without constantly writing the offset into the same page?

2012-06-20T21:39:14 < zyp> dekar, bullshit, old assemblers would lack other modern instructions as well, and are just as useless either way
2012-06-20T21:39:56 <+dekar> zyp, what if the target was an ARMv4? I am pretty sure you can still get the ARM7-TDMI for example
2012-06-20T21:41:08 < Thorn> that's what it probably was
2012-06-20T21:41:18 < Thorn> ARM7TDMI is ARMv4
2012-06-20T21:41:35 < zyp> dekar, why would code for ARMv4 contain svc?
2012-06-20T21:42:01 <+dekar> zyp, cause SWI is deprecated? it's AVC now
2012-06-20T21:42:26 <+dekar> imagine different developers working with different compilers on the same project
2012-06-20T21:42:50 <+dekar> I don't say that the problem is uber likely to occur, I just mean it can and probably did happen
2012-06-20T21:43:07 < FUZxxl> dekar: GNU as still accepts the old SWI mnemnoric. I wonder why they should drop support

2012-06-20T21:43:20 < zyp> it's not «now» it's «on ARMv7», and that's irrelevant for ARMv4
2012-06-20T21:44:35 <+dekar> FUZxxl, I didn't suggest they would
2012-06-20T21:44:55 < zyp> even if the assembler supports the old mnemonic when assembling for a newer architecture, it's not given that the new mnemonic is supported when assembling for an other architecture

2012-06-20T22:20:28 < karlp> anyone think the pdf tutorial in the texane/stlink repo is at all useful?
2012-06-20T22:34:41 < FUZxxl> karlp: I think it is - but only a little bit
2012-06-20T22:38:41 < karlp> ok then. my first pull request in a while.  killing the examples and updating the docs :)

--- Day changed Thu Jun 21 2012
2012-06-21T00:07:09 < szczys> karlp: with git you probably want to use diff with the --name-only flag
2012-06-21T00:07:30 < szczys> That will show you which files differ between commits
2012-06-21T00:07:37 < szczys> without including each line of changed code
2012-06-21T00:15:00 < szczys> So I'm trying to use generic startup and linker script from CMSIS 3.0
2012-06-21T00:15:10 < szczys> It works fine with my own super-simple sample code
2012-06-21T00:15:23 < szczys> but I can't get the STM demo code to run
2012-06-21T00:15:32 < szczys> the led comes on but it should be blinking and it's not
2012-06-21T00:16:00 < szczys> I see from the STM startup file that SystemInit() is run by the startup code and that's not happening with the CMSIS code
2012-06-21T00:16:30 < szczys> neither is the function: __libc_init_array
2012-06-21T00:16:44 < szczys> Am I barking up the wrong tree by trying to use these files, or should I keep steaming ahead?

2012-06-21T00:29:15 <+dekar> szczys, did you get a linker script yet?
2012-06-21T00:29:34 <+dekar> I can give you one licensed under a more permissive license
2012-06-21T00:29:36 < szczys> yes, there's a linker script in the CMSIS 3.0 library
2012-06-21T00:29:47 < szczys> it has a startup script that goes along with it
2012-06-21T00:29:56 <+dekar> kay
2012-06-21T00:30:06 < szczys> https://github.com/szczys/stm32f0-discovery-basic-template/tree/development/Device
2012-06-21T00:30:19 < szczys> But like I said, the demo code for the F0-Discovery board isn't working
2012-06-21T00:30:28 < szczys> and I'm not sure why (or how to find out why)
2012-06-21T00:31:27 <+dekar> szczys, though that linker script references proprietary codesourcery libs, so other toolchains likely won't work
2012-06-21T00:31:58 < szczys> which linker script are you speaking of?
2012-06-21T00:32:06 <+dekar> the one you just linked
2012-06-21T00:32:24 <+dekar> -lcs3 -lcs3unhosted -lcs3micro
2012-06-21T00:32:33 <+dekar> cs = codesourcery
2012-06-21T00:32:42 <+dekar> they don't release the source for those afaik
2012-06-21T00:32:47 < Thorn> what's the point in that cs3 stuff anyway?
2012-06-21T00:33:06 <+dekar> Thorn, it contains newlib stubs I think
2012-06-21T00:33:10 <+dekar> maybe some other stuff
2012-06-21T00:33:24 < Thorn> do they do something you can't do yourself?
2012-06-21T00:33:42 <+dekar> Thorn, probably not ;)
2012-06-21T00:33:52 < szczys> hmm...
2012-06-21T00:33:56 <+dekar> szczys, you might wanna try this one: https://dl.dropbox.com/u/28467113/stm32_linkerscript/TNT.zip
2012-06-21T00:34:15 < Thorn> I remember the LPC standard library relies heavily on cs3
2012-06-21T00:34:16 < szczys> yeah, another guy issued a pull request with a linker that worked for him
2012-06-21T00:34:28 < szczys> but I'm using the CodeSorcery G++ toolchain
2012-06-21T00:34:36 < szczys> and got a libnosys.a error
2012-06-21T00:34:42 < szczys> (which I believe is related to newlib)
2012-06-21T00:34:53 <+dekar> szczys, CS has newlib as well
2012-06-21T00:34:54 < drgreenthumb> heh Thorn I went to look at what CPLD was used in that video project you mentioned yesterday. looks like max2, nice I like Altera. but heh in Russia you can buy CPLDs at Radio Shack?! :o
2012-06-21T00:34:55 < szczys> do you think I should bite the bullet and dump this toolchain for the GNU toolchain?
2012-06-21T00:35:24 <+dekar> szczys, you should be able to use the CS-toolchain with the TNT linker script
2012-06-21T00:35:39 < Thorn> drgreenthumb: yes it was a EPM240. and no Radio Shack in Russia :)
2012-06-21T00:35:46 < szczys> doesn't the startup code have to match the linker script?
2012-06-21T00:36:04 < drgreenthumb> Thorn, heh must be google translate messing with me
2012-06-21T00:36:10 <+dekar> szczys, the startup code shouldn't do much, should it?
2012-06-21T00:36:12 < drgreenthumb> http://translate.google.com/translate?sl=auto&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fmarsohod.org%2Findex.php%2Fprojects%2F174-phframe3&act=url
2012-06-21T00:36:24 < drgreenthumb> oh srt
2012-06-21T00:36:26 < drgreenthumb> sry
2012-06-21T00:36:38 < szczys> looking at TNT.zip... which .ld do you suggest using?
2012-06-21T00:37:09 <+dekar> "EXTERN(__cs3_interrupt_vector_cortex_m)" <-- all of those are codesourcery specific on the script you're using
2012-06-21T00:37:31 <+dekar> szczys, the tnt one includes the others
2012-06-21T00:37:39 < szczys> oh, I see
2012-06-21T00:37:42 <+dekar> well I ripped them out of my project when someone asked me for them
2012-06-21T00:37:56 <+dekar> someone who was reading your tutorial btw
2012-06-21T00:37:59 < szczys> is __Stack_Size basically talking about on-chip RAM?
2012-06-21T00:38:01 <+dekar> a day or two ago
2012-06-21T00:38:02 < drgreenthumb> here Thorn, that's what I meant http://translate.googleusercontent.com/translate_c?act=url&hl=en&ie=UTF8&prev=_t&rurl=translate.google.com&sl=auto&tl=en&twu=1&u=http://marsohod.org/index.php/howtobuy&usg=ALkJrhgpTVEsPuW7OOvJ9ar--UygaRd5yw ... stupid google frames it. "If you are lucky and you live in the beautiful city of Taganrog, you can buy a motherboard rover in a Radio Shack." wat? :)
2012-06-21T00:38:12 <+dekar> szczys, yeah
2012-06-21T00:38:30 < szczys> so I need to go through these files and change the addresses to match this chip, right?
2012-06-21T00:39:09 < Thorn> drgreenthumb: lol @ google translate, it simply says "local electronics store"
2012-06-21T00:39:11 <+dekar> szczys, you probably have to change some things, I am using it for an stm32f1 with 64kb ram, I also use the split linker script to easily change parts when building bootloader/firmware
2012-06-21T00:40:05 < szczys> did you write these?
2012-06-21T00:40:59 <+dekar> szczys, nope, check the header - I found them somewhere
2012-06-21T00:41:12 <+dekar> I think I had their IDE installed
2012-06-21T00:41:21 <+dekar> or somewhere on the web, idk
2012-06-21T00:41:34 <+dekar> I just modified them a bit
2012-06-21T00:41:46 < szczys> do you know what these definitions are for:
2012-06-21T00:41:46 < szczys>   FLASHB1 (rx) : ORIGIN = 0x00000000, LENGTH = 0
2012-06-21T00:41:46 < szczys>   EXTMEMB0 (rx) : ORIGIN = 0x00000000, LENGTH = 0
2012-06-21T00:42:04 <+dekar> szczys, you can remove those
2012-06-21T00:42:15 <+dekar> their likerscripts contain a lot stuff for other chips
2012-06-21T00:42:15 < szczys> okay, thanks
2012-06-21T00:42:53 <+dekar> szczys, I was the guy who posted the legal hint at hackaday btw
2012-06-21T00:43:02 < szczys> oh, thanks!
2012-06-21T00:43:07 <+dekar> didn't mean to offend you, people here told me I was trolling :/
2012-06-21T00:43:17 < szczys> no, I disagree
2012-06-21T00:43:26 < szczys> you're not the asshat who put a copyrighted file in that library
2012-06-21T00:43:30 <+dekar> I just have to watch for those things at work and it became a habit :)
2012-06-21T00:43:34 < szczys> I read the license that STM distributed
2012-06-21T00:43:47 < szczys> so it's a big surprise to fine that kind of copyright hidden in a file header
2012-06-21T00:44:01 < szczys> I mean, why would I be looking inside the linker script file if it works?
2012-06-21T00:44:32 <+dekar> szczys, well cause you were using a linker script placed in a subfolder with the name of some IDE you're not using
2012-06-21T00:44:50 <+dekar> but it isn't too obvious
2012-06-21T00:45:15 <+dekar> I guess ST assumed you would use the content of those folders only if you had a license for the specific compiler/IDE/toolchain
2012-06-21T00:45:23 < BrainDamage> dekar: people here tell you that you troll to troll you
2012-06-21T00:45:41 <+dekar> BrainDamage, I feel seriously trolled now :/
2012-06-21T00:45:46 <+dekar> :P
2012-06-21T00:47:25  * szczys digging through massive reference manual
2012-06-21T00:48:11 <+dekar> szczys, in the sections_ file there is also a ton of "for Cortex LPC devices", you can remove all of that if you care
2012-06-21T00:48:25 < szczys> I was just looking at those
2012-06-21T00:48:40 < szczys> but now I'm trying to figure out how much of this peripheral memory map I need to double-check
2012-06-21T00:49:45 < szczys> this is marked reserverd: PERIPH_BB_BASE        = 0x42000000;
2012-06-21T00:49:49 < szczys> so I guess that needs to change
2012-06-21T00:50:26 < Thorn> for a simple linker script all you need to know is rom and flash and their addresses and sizes
2012-06-21T00:50:33 <+dekar> szczys, there are also two lines in the file I patched, those have a comment
2012-06-21T00:50:38 < Thorn> *ram and flash
2012-06-21T00:51:03 < Thorn> flash in stm32 starts at 0x0800 0000, ram always starts at 0x2000 000
2012-06-21T00:51:32 <+dekar> yeah, you need an interrupt vector, .data, .text and that's about it
2012-06-21T00:51:52 < Thorn> also stack and .bss
2012-06-21T00:52:20 <+dekar> right, though the stack is set in the interrupt pointer, isn't it?
2012-06-21T00:52:24 < Thorn> (stack only to check that it doesn't overlap with .data/.bss)
2012-06-21T00:52:36 <+dekar> *interrupt vector
2012-06-21T00:54:36 < Thorn> well standard f1 startup code uses a symbol defined in the linker script to set beginning of stack. so it's important to specify ram size in the linker script
2012-06-21T00:54:40 < szczys> so why to they complicate things with all this other stuff... there must be a reason?
2012-06-21T00:56:07 <+dekar> Thorn, I did actually have a funny effect with that linker script when I activated -fdata-sections. when the .bss section was split up into .bss.subsections the linker script didn't match and place them anymore. as a result the startup code didn't init the bss section
2012-06-21T00:56:58 <+dekar> I think cold booting still worked fine, but calling the firmware from my bootloader went really weird, got into impossible states
2012-06-21T00:57:05 < Thorn> I think you need to have *(.bss .bss.*) rather than simply *(.bss) for this to work
2012-06-21T00:57:13 <+dekar> yeah I did fix it
2012-06-21T00:57:29 <+dekar> just saw my fix when I had a look at the script I linked to szczys
2012-06-21T00:57:38 <+dekar> but it took me a while to find back then :)
2012-06-21T00:58:02 < Thorn> yeah that's not a problem that's pleasant to debug
2012-06-21T00:58:38 < Thorn> what is all this *(.plt) *(.jcr) *(.got.plt) *(.got) *(.shdata) etc. stuff?
2012-06-21T00:59:01 < Thorn> from the script linked by szczys
2012-06-21T00:59:46 <+dekar> lol no idea
2012-06-21T00:59:54 <+dekar> that codesourcery stuff is weird
2012-06-21T01:00:06 <+dekar> I didn't like how they renamed all the interrupt handlers as well
2012-06-21T01:03:18 < Thorn> _end = .; __end = .;  because one symbol simply isn't enough apparently
2012-06-21T01:06:24 < szczys> what is the alias region? :
2012-06-21T01:06:43 < szczys> wondering because of this: Peripheral and SRAM base address in the alias region
2012-06-21T01:11:00 <+dekar> szczys, some arm cortex features I think
2012-06-21T01:11:36 < Thorn> rom is aliased, but not peripherals or sram?
2012-06-21T01:11:40 <+dekar> you can for example remap memory to the bit-band region and then set/reset single bits without the load-modify-store
2012-06-21T01:11:55 < szczys> oh, I see
2012-06-21T01:12:02 < szczys> why do we need this memory map in the linker?
2012-06-21T01:12:23 <+dekar> what particular part of the script do you mean?
2012-06-21T01:13:24 < szczys> STM32F10x_COMMON.ld
2012-06-21T01:13:33 < szczys> last half of the file is a big memory map
2012-06-21T01:14:23 <+dekar> It says: /*this allows to compile the ST lib in "non-debug" mode*/
2012-06-21T01:14:42 <+dekar> I guess the ST libs (probably the old 2.X version) needs that
2012-06-21T01:16:12 <+dekar> szczys, I kinda dislike how the comments at hack a day give ST a hard time for the Atollic license
2012-06-21T01:17:08 <+dekar> ST only bundles Atollic TrueSTUDIO demo projects
2012-06-21T01:17:33 <+dekar> so they're not really involved with that license, they just offer you an example that contained the license
2012-06-21T01:18:13 < szczys> this is a nightmare
2012-06-21T01:18:16 < szczys> I give up
2012-06-21T01:18:23 < szczys> thanks or the help though

2012-06-21T02:58:19 < karlp> they shouldn't be included in the distribution

Anyone who bothers with Kickstarter is missing that working part of the brain that says "don't get involved with scams or anything to do with them".
2012-06-21T15:27:24 < cjbaird-vt220> "But I'm intelligent! I would know when something is a scam~~" --what 99% of everyone who gets scams said at one point...
2012-06-21T15:30:18 <+Steffanx> And interesting project never get released
2012-06-21T15:30:27 <+Steffanx> Like the IsoStick.. still not finished
2012-06-21T15:30:38 <+Steffanx> The openvizsla also looked pretty nice, still not finished
2012-06-21T15:31:07 <+Steffanx> "This project successfully raised its funding goal on December 22, 2010." .. whoa even longer than i thought
2012-06-21T15:31:29 < cjbaird-vt220> The basic idea of Kickstarter sounds good-- but so did eBay's ...but then /humans/ got involved.
2012-06-21T15:31:43 <+Steffanx> I never had trouble with ebay
2012-06-21T15:31:54 <+Steffanx> The local ebay-ish place is worse
2012-06-21T15:32:59 < cjbaird-vt220> I won't use it, but friends were seeing bad sellers for 2 out of every 3 won auctions, and then /they/ gave up on it.
2012-06-21T15:33:23 <+Steffanx> I never enter auctions, i only use the 'buy now'  option
2012-06-21T15:34:06 < cjbaird-vt220> Usually for new products as well?
2012-06-21T15:34:38 <+Steffanx> Yep

2012-06-21T15:38:24 < BrainDamage> the only time I had an issue with fleabay was that a package never arrived, I sent a mail to the seller, and they shipped a replacement for free
2012-06-21T15:38:40 < BrainDamage> this in years, and 100+ auctions
2012-06-21T15:38:48 <+Steffanx> My sarcasm detector should detect something now cjbaird-vt220 ?

2012-06-21T15:41:32 < cjbaird-vt220> Charl's last auction was for some kind of alternative keyboard ("frogpad"?), "New, in box, never used..."  Seller wanted an extra $40 for shipping over the listed shipping, ..and it arrives in standard-mail, the device alone in a sticky-taped box, no manuals, software, etc. The Seller of course did the usual scammer "I'll wear you out before you get PayPal to do anything" routine..
2012-06-21T15:42:41 < cjbaird-vt220> Steffanx: actually, no.. Charl never had any complaints from the HK sellers-- when there was an issue, their email support got straight on it,.

2012-06-21T16:41:35 < dongs> here's some Laurenceb-class coding
2012-06-21T16:42:05 <+Steffanx> WTF dongs
2012-06-21T16:42:22 < dongs> i kno rite
2012-06-21T16:42:31 < dongs> actually cookies if you figure out waht hte FUCK that does
2012-06-21T16:45:23 <+Steffanx> I wonder what the input should be
2012-06-21T16:45:41 <+Steffanx> bX .. . a single it?
2012-06-21T16:45:53 < dongs> dunno, gonna grep the sores to see where the fuck its used
2012-06-21T16:46:21 < dongs> Bus\Bus_I2C.h:                  I_DATA_L_NOP  = BIT_4(1,0,0,0),
2012-06-21T16:46:24 <+Steffanx> It just looks like some fancy way to set bits, but …
2012-06-21T16:46:55 < dongs> 22_T.h:                 layer ^= BIT_3(1,1,1);
2012-06-21T16:47:29 <+Steffanx> Some one who doesn't want to write 0x07 or 7 i guess
2012-06-21T16:47:34 < dongs> yeah..

2012-06-21T16:52:22 < cjbaird> The results from that preprocessor hack isn't very compiler optimizer friendly..
2012-06-21T16:52:52 < dongs> i hope it actually ends up just turning into 0x07
2012-06-21T16:52:57 < dongs> and not 2k of asm

2012-06-21T16:53:31 < dongs> im not using that C++ filth
2012-06-21T16:53:32 <+Steffanx> Ha karlp
2012-06-21T16:53:32 < cjbaird> "BIT_4(1,1,0,0)" becomes " static_cast<uint32>((1 )<< 3 | static_cast<uint32>((1 )<< 2 | static_cast<uint32>((0 )<< 1 | static_cast<uint32>((0 )<< 0 ))))" .. and I'd think current GCC would do the Wrong Thing with all that..
2012-06-21T16:54:12 < cjbaird> Well, maybe not so much with constant values..

2012-06-21T17:06:45 < Thorn> clang does, because it supports almost all of c++11

2012-06-21T21:06:31 <+Steffanx> oh, it's not compatible yet?
2012-06-21T21:06:44 < karlp> not sure if szczys has finished his work.
2012-06-21T21:06:54 < karlp> his github commits make it look like it's not ready yet.
2012-06-21T21:07:07 <+Steffanx> dekar is really proud of his TNT, so use TNT :P
2012-06-21T21:07:09 < karlp> not quite sure why it's taking him so long, it's the same flash loader as the f1...
2012-06-21T21:07:18 <+Steffanx> He claims smaller code size etc.  :P
2012-06-21T21:08:03 < r0b-> ok
2012-06-21T21:08:04 < r0b-> :P
2012-06-21T21:08:50 <+Steffanx> but they all work, so it doesn't matter what you start with imho

2012-06-21T23:24:06 < Laurenceb_> its very CS guru, but a little limited in the real world
2012-06-21T23:26:09 < BrainDamage> having to support multiple platforms ususally also restricts your flexibility as well
2012-06-21T23:26:19 < BrainDamage> like not be able to use the full capability of each device
2012-06-21T23:29:48 < karlp> someone here was talking about wanting the gdb server to stay active when gdb detaches.
2012-06-21T23:29:54 < karlp> but what should that do?
2012-06-21T23:30:14 < karlp> if I do "continue; ctrl-c; ctrl-d" to get out of gdb, it sends a "kill" command to the gdbserver.
2012-06-21T23:30:17 < BrainDamage> remain connected to the board and reopen a tcp socket?
2012-06-21T23:30:30 < karlp> should the target continue? or be left halted?
2012-06-21T23:30:48 < BrainDamage> I would say, remain in which state it is
2012-06-21T23:30:49 < karlp> like if I use st-flash write.... it flashes, then the target is reset and continues.
2012-06-21T23:30:53 < karlp> remain in what state?
2012-06-21T23:30:56 < karlp> if I do monitor resume,
2012-06-21T23:31:06 < karlp> so I don't have to ctrl-c the target, and halt it.
2012-06-21T23:31:16 < karlp> when I press ctrl-d, gdb still sends a kill command.
2012-06-21T23:31:54 < BrainDamage> I don't know what monitor does
2012-06-21T23:31:57 < BrainDamage> I know resume
2012-06-21T23:32:20 < karlp> monitor just sends commands to the gdb server directly.
2012-06-21T23:32:31 < karlp> there's no resume command in gdb directly,
2012-06-21T23:32:43 < karlp> basically, monitor resume is like continue, but you stay at a working gdb prompt
2012-06-21T23:33:53 < BrainDamage> I don't understand why gdb itself would want to kill the remote server process
2012-06-21T23:33:59 < BrainDamage> it sounds unnecessary to me

2012-06-22T04:45:18 < Rickta59> link to article dekar?
2012-06-22T04:46:13 < szczys> dekar, that is interesting
2012-06-22T04:46:36 < szczys> so if space is not a problem just define everything as signed
2012-06-22T04:46:53 < szczys> and bump up to the next variable size if necessary?
2012-06-22T04:46:57 < BrainDamage> well, you only gain 1 bit with signed vs unsigned
2012-06-22T04:47:14 < BrainDamage> you must be really tight on space to have to resort to it
2012-06-22T04:47:20 < szczys> but he's saying the code is better optimized
2012-06-22T04:47:30 < szczys> so it may run faster
2012-06-22T04:47:33 < szczys> isn't that the point?
2012-06-22T04:47:53 < szczys> I also would be interested in reading this article
2012-06-22T04:48:15 < BrainDamage> having everything signed is the lazy way, not the opposite, so there's no buts, it's a win win situation :p
2012-06-22T04:49:34 < BrainDamage> ( I've seen plenty of bugs due to signed <-> unsigned implicit casting resulting in negative or max(uint) results )
2012-06-22T04:50:40 <+dekar> Rickta59, szczys http://blog.llvm.org/2011/05/what-every-c-programmer-should-know.html
2012-06-22T04:50:41 < Rickta59> this one? http://stackoverflow.com/questions/410982/is-there-a-difference-in-term-of-performance-between-unsigned-int-and-int-on
2012-06-22T04:51:23 < Rickta59> so is this an llvm only quirk?
2012-06-22T04:51:30 <+dekar> Rickta59, nope
2012-06-22T04:52:31 < Rickta59> thanks .. reading
2012-06-22T04:52:46 < szczys> but you have to use the compiler flag -fwrapv to take advantage of the optimizations
2012-06-22T04:52:52 < Rickta59> interesting ..so are you using llvm?
2012-06-22T04:52:57 <+dekar> I was referencing the part about: "Signed integer overflow"
2012-06-22T04:53:21 <+dekar> Rickta59, it's the default on OSX
2012-06-22T04:54:34 <+dekar> szczys, you got it wrong, it is able to optimize _because_ of the undefined behavior. the flag you mention disables the optimization due the defining the signed overflow
2012-06-22T04:55:23 < szczys> oh yes, I see now
2012-06-22T04:55:25 < szczys> thanks
2012-06-22T04:55:51 < Rickta59> have you compared llvm generated code vs gcc?
2012-06-22T04:55:57 <+dekar> nope
2012-06-22T04:56:07 <+dekar> gcc is usually 10% faster
2012-06-22T04:56:19 <+dekar> code size is usually comparable at -O2
2012-06-22T04:56:20 < Rickta59> how about code size?
2012-06-22T04:56:24 < Rickta59> k
2012-06-22T04:56:59 <+dekar> but there are extreme examples (real life examples) where one or the other has quite extreme speed advantages
2012-06-22T04:57:32 < Rickta59> 3 or 4 years ago I was playing around with actionscript compiled with llvm
2012-06-22T04:57:49 < Rickta59> but in the end it was only bytecode anyway
2012-06-22T04:57:51 <+dekar> gcc has much lower compile speed, though that probably has changed with LTO and Gold
2012-06-22T04:58:14 < dongs> trusting shit written by llvm dudes who're just there to peddle their warez, passing out their misconceptions as facts
2012-06-22T04:58:23 < Rickta59> heh
2012-06-22T04:58:32 < BrainDamage> and then there's dongs
2012-06-22T04:58:44 < Rickta59> not knowing arm asm .. i can't say
2012-06-22T04:58:50 < BrainDamage> ##stm32's authority on compiler behaviour
2012-06-22T04:58:53 < Rickta59> seemed pretty dense and reasonable to me
2012-06-22T04:58:59 < Rickta59> gcc that is
2012-06-22T04:59:48 <+dekar> I don't like GCC too much, had it segfault on me once in a while
2012-06-22T05:00:24 <+dekar> but the results are usually performing quite nice

2012-06-22T05:06:31 < Rickta59> i wish stm would just generate some ldscripts and be done with it
2012-06-22T05:07:01 <+dekar> Rickta59, for all possible toolchains?
2012-06-22T05:07:13 < Rickta59> just some generic ld scripts for the f0 board
2012-06-22T05:07:18 <+dekar> different linkers want different scrips
2012-06-22T05:07:19 < Rickta59> for a generic gcc
2012-06-22T05:07:43 < Rickta59> i think that one i have should work with most as long as they use the same startup no?

2012-06-22T05:08:57 < Rickta59> gold is a superset?
2012-06-22T05:09:20 <+dekar> Rickta59, there's no magic involved in linker scripts and startup code, just check which information they share and adjust
2012-06-22T05:09:52 <+dekar> gold is some contribution by google, I think it is supposed to replace LD on long term
2012-06-22T05:10:16 <+dekar> it links like 5 times faster which is quite relevant when using LTO
2012-06-22T05:10:40 < Rickta59> i can't really say that compiling mcu code is slow
2012-06-22T05:10:56 < Rickta59> it isn't like compiling 500k lines of stl template stuff
2012-06-22T05:12:03 <+dekar> Rickta59, my firmware is growing a lot lately, I've added a crypto lib as well as a lua compiler and lua byte code VM
2012-06-22T05:12:18 < Rickta59> does it take more than 2 minutes to compile?
2012-06-22T05:12:32 <+dekar> probably around 1min
2012-06-22T05:12:50 < Rickta59> i've worked on projects that took 30 minutes to compile and link the whole system
2012-06-22T05:13:03 < Rickta59> granted that was 15+ years ago
2012-06-22T05:13:24 < Rickta59> and now my arm is faster than most of the machines i used back then :)
2012-06-22T05:14:01 <+dekar> Rickta59, about the linkerscript. I don't think those have enough threshold of originality to begin with. especially for your stripped version. so it's questionable whether they can actually be copyrighted
2012-06-22T05:14:21 <+dekar> IANAL though, especially not for US law
2012-06-22T05:14:23 < Rickta59> i just left it in
2012-06-22T05:14:45 < Rickta59> i don't really know the right thing to do there ..
2012-06-22T05:14:48 <+dekar> yeah, I just mean it probably isn't too much of a deal anymore - even that scripts heritage
2012-06-22T05:15:09 < Rickta59> i took out more than i added
2012-06-22T05:15:28 < Rickta59> and just adjusted a few lengths
2012-06-22T05:15:41 <+dekar> and removed some sanity checks...
2012-06-22T05:15:52 < Rickta59> i probably should have left in the smarts about the ram and such
2012-06-22T05:16:10 < Rickta59> i was just trying to see how much i could take out to get it to still work
2012-06-22T05:16:33 <+dekar> doesn't the sat project have an LGPL licensed linker script you could steal?
2012-06-22T05:16:48 <+dekar> in case you want to be sure of the origin
2012-06-22T05:17:20 < Rickta59> hmm .. yes there does seem to be some in there .. let me go look at them
2012-06-22T05:17:27 <+dekar> though I just think you should mail raisonance and ask them if you're unsure
2012-06-22T05:18:21 <+dekar> I personally don't like GPL derivates too much

2012-06-22T06:10:37 < zippe> dongs: seriously?  objcopy does all that
2012-06-22T06:10:53 < dongs> seriously to which part
2012-06-22T06:10:57 < dongs> im not using objcopy.
2012-06-22T06:11:04 < zippe> Mmk.
2012-06-22T06:11:17 < zippe> So if you have a bootloader, it's living at the bottom of flash (assuming stm32 here)
2012-06-22T06:11:21 < dongs> right
2012-06-22T06:11:45 < zippe> So in your app startup code, you need to reset the vector base register to point to your vectors.
2012-06-22T06:11:57 < dongs> thats all?
2012-06-22T06:12:01 < zippe> Ya
2012-06-22T06:12:25 < zippe> If you've told your toolchain that you want to be based at some other address, then the .hex output Should Just Work™
2012-06-22T06:13:05 < zippe> You can do the vector base relocation in the bootloader if you like, but that assumes you have a contract with the app about where your vectors go
2012-06-22T06:13:10 < zippe> That's not always desirable...
2012-06-22T06:13:26 < dongs> what about debugging
2012-06-22T06:13:35 < dongs> when I load my app for debugging, what happens?
2012-06-22T06:14:42 < zippe> What do you mean?
2012-06-22T06:15:17 < zippe> Assuming you have a global array of vectors, and you're using the symbol that points to the array, you can put the vectors anywhere.
2012-06-22T06:15:28 < zippe> So if by "load for debugging" you mean "load to RAM", it'll still work
2012-06-22T06:15:48 < zippe> I don't know what your gooey does when you "load for debugging"
2012-06-22T06:16:07 < dongs> no, of course its in flash
2012-06-22T06:16:29 < zippe> Ok, then I'm not sure what the difference between "load for debugging" and "load for ripping off the customer" might be
2012-06-22T06:16:49 < zippe> I can probably be more specific if you can give me more details
2012-06-22T06:17:06 < zippe> Are you worried about things like the debugger catching interrupts, etc?
2012-06-22T06:17:25 < dongs> im just worried about it working in general
2012-06-22T06:17:29 < dongs> the hardware will start from bootloader right?
2012-06-22T06:17:34 < dongs> then jump to my app address?
2012-06-22T06:18:03 < zippe> Assuming the bootloader works, yes
2012-06-22T06:18:25 < zippe> The usual convention for booloaders on the CM3 is that they pretend that the ROM starts a few K higher than normal
2012-06-22T06:19:03 < zippe> so say you're on an F1 and you fit your bootloader in 2k.  Then you link your app as though the ROM started at 0x0800800

2012-06-22T06:19:27 < zippe> er, add the appropriate zero where it obviously goes there
2012-06-22T06:19:43 < pepsi_> 00x0800800
2012-06-22T06:20:17 < zippe> That puts the vector table 2k offset from the base of the ROM.  The bootloader will usually look at the first two words and pretend it's the CM3 coming out of reset; it'll load the first word into MSP and the second into PC.
2012-06-22T06:20:51 < zippe> At which point your entry function is running, but the vectors still point to the bootloader's handlers.  It's your job to fix up the NVIC as soon as you're ready to handle interrupts.
2012-06-22T06:21:06 < dongs> right.

2012-06-22T06:24:20 < dongs> thats terrible
2012-06-22T06:24:37 < zippe> The HID stack will assume you are telling the truth, and it will assume you are going to send HID events.

2012-06-22T10:27:36 <+dekar> OSX allows you to access HID devices via their HID api
2012-06-22T10:28:33 <+dekar> also HID doesn't mean "but really, I'm a mouse", the HID device class is so much more than that

2012-06-22T10:46:55 < dongs> either that uavtalk shit only sent quats or something to that effect
2012-06-22T10:47:17 < dongs> anyhow, i duplicated GLC's quat2rpy() shit but its hilariously broken
2012-06-22T10:47:24 < Laurenceb_> unfortunatly uavtalk sends roll pitch yaw
2012-06-22T10:47:28 < Laurenceb_> and quats
2012-06-22T10:47:34 < Laurenceb_> for some retarded reason
2012-06-22T10:47:58 < dongs> it seems to show stuff in Earth frame, so when i rotate the board 90 degrees in yaw, roll is then shown as pitch
2012-06-22T10:48:05 < Laurenceb_> i use quat2rpy from opanpilot
2012-06-22T10:48:10 < dongs> thats hte lame one

2012-06-22T15:16:07 < dongs> i didnt do that on my board.
2012-06-22T15:16:11 < dongs> im wondering what they're doing exactly
2012-06-22T15:16:16 < dongs> pulling one of D lines? or osmehting

2012-06-22T17:24:55 < dongs> whats your pll setup looks like for 12mhz
2012-06-22T17:25:05 < Laurenceb> i use st periph lib
2012-06-22T17:25:14 < dongs> right
2012-06-22T17:25:17 < Laurenceb> its on github, check my logger project
2012-06-22T17:25:20 < dongs> so you just define HSE_VALUE=1200000 or whatever
2012-06-22T17:25:31 < Laurenceb> yeah, in the makefile
2012-06-22T17:25:59 < dongs> ugh
2012-06-22T17:26:04 < dongs> i remember why I dont often look at your code
2012-06-22T17:32:20 < dongs> looks like 99% standard ST code
2012-06-22T17:32:25 < dongs> i must be missing something really dumb

2012-06-22T17:43:04 < dongs> hmm, added 7 months ago
2012-06-22T17:43:17 < dongs> but i guess that pll_blah change is the only one..
2012-06-22T17:49:19 < dongs> haha
2012-06-22T17:49:29 < dongs> seems i can run this f103 at 120mhz
2012-06-22T17:49:30 < dongs> ??
2012-06-22T17:49:38 < dongs> i did 12*PLL_10 as a test
2012-06-22T17:49:38 < dongs> heh
2012-06-22T17:51:24 <+Steffanx> dekar made it run up to 128mhz iirc
2012-06-22T17:53:01 < dongs> something is fucked
2012-06-22T17:53:06 < dongs> my 100ms delay ends up being 133ms on scope
2012-06-22T18:00:53 < Laurenceb> wait do you have 12mhz xtal?
2012-06-22T18:01:03 < dongs> of course.
2012-06-22T18:01:13 < Laurenceb> then just rip my system code
2012-06-22T18:01:18 < Laurenceb> as it works
2012-06-22T18:01:27 < dongs> no,your code is from old stdperiphlib
2012-06-22T18:01:29 < dongs> thing is
2012-06-22T18:01:35 < dongs> if I define HSE_VALUE
2012-06-22T18:01:40 < dongs> changing that pll s caler has zero effect

2012-06-22T18:09:14 < dongs> haha wtf
2012-06-22T18:09:27 < dongs> 33ms period...so 16.5ms out of 100ms delay
2012-06-22T18:09:30 < dongs> i wonder what speed that runs at
2012-06-22T18:09:53 < dongs> led was blinking super fast.
2012-06-22T18:15:55 < zyp> sup
2012-06-22T18:16:13 < dongs> calculate how much I overclocked this shit by :)
2012-06-22T18:16:23 < dongs> i had a led blinking w/delayus(100);
2012-06-22T18:16:30 < dongs> period on scope was 33us
2012-06-22T18:16:42 < dongs> so 100us delay was turning into 16.5us
2012-06-22T18:16:49 < zyp> right
2012-06-22T18:16:51 < dongs> 100us @ 72mhz
2012-06-22T18:17:16 < dongs> i think it needs a proportion or some other advanced math
2012-06-22T18:17:51 < zyp> sounds weird that it would be stable at six times the rated maximum, so I'm betting on measurement error or something
2012-06-22T18:17:58 < dongs> how so
2012-06-22T18:18:08 < dongs> all im doing is while (1) { toggle; delay; }
2012-06-22T18:19:05 < zyp> but it's still stable, right?
2012-06-22T18:19:12 < dongs> well, it blinked stably
2012-06-22T18:19:14 < dongs> if thats what you mean
2012-06-22T18:19:34 < dongs> how much mhz was it? i did a proportion shit but I think i failed cuz i got 11.88
2012-06-22T18:20:41 < zyp> if the delay was turning into 16.67us, it was six times,
2012-06-22T18:20:55 < dongs> o rite
2012-06-22T18:20:58 < dongs> so uh
2012-06-22T18:21:03 < dongs> 432mhz rly?
2012-06-22T18:21:09 <+Steffanx> Sure ...
2012-06-22T18:21:49 < dongs> any other explanation?
2012-06-22T18:21:49 < zyp> I don't believe it, at least not until I've tried it :p
2012-06-22T18:22:09 < zyp> what is the time source for the delay?

2012-06-22T18:22:33 < dongs> as in DWT_CYCCNT
2012-06-22T18:23:06 < zyp> and how does the code for that look?

2012-06-22T18:24:49 < zyp> ah, right
2012-06-22T18:25:13 < zyp> so, do you have the values you put into the RCC registers?
2012-06-22T18:25:26 < dongs> I can repeat it again.

2012-06-22T18:40:45 < zyp> the PLL input can be either HSE, HSE/2 or HSE/4 (when using HSE), and then that's multiplied 2-17 times

2012-06-22T18:47:12 < zippe> Yes, but look at the actual code
2012-06-22T18:48:04 < dongs> i dont see it doing anything crazy wiht hse-value
2012-06-22T18:48:43 < zippe> Is it actually using it to compute the PLL constants?
2012-06-22T18:49:12 < zippe> Older versions of the library, at least, just hardcoded the M and N values

2012-06-22T18:50:47 < zippe> You're on a non-CL device?
2012-06-22T18:50:54 < dongs> right, f103_md
2012-06-22T18:51:22 < zippe> I don't see you setting the pre-divider
2012-06-22T18:51:31 < dongs> which register is it
2012-06-22T18:51:56 < zippe> bit 17 in CFGR
2012-06-22T18:51:57 < dongs> http://bcas.tv/paste/results/oG0Lmw80.html heres hte entire file, its just copypaste 1:1 of latest ST's code
2012-06-22T18:52:05 < zippe> should be set to 1
2012-06-22T18:52:20 < zippe> In fact, it's cleared
2012-06-22T18:52:28 < zippe> Hmm, nvm
2012-06-22T18:52:43 < zippe> They are running the PLL input at 12MHz
2012-06-22T18:52:56 < zippe> Keep forgetting the F10x will go that fast
2012-06-22T18:53:12 < karlp> f100 is the only speed limited one.
2012-06-22T18:54:50 < zippe> karlp: hm?  F2/F4 PLL wants 1-2MHz input as well.
2012-06-22T18:55:07 < dongs> well what the hell is going on hmm
2012-06-22T18:55:45 < Laurenceb> oh
2012-06-22T18:55:51 < Laurenceb> its a dodgey makefile nvm
2012-06-22T18:56:19 < zippe> RCC->CFGR &= (uint32_t)((uint32_t)~(RCC_CFGR_PLLSRC | RCC_CFGR_PLLXTPRE |
2012-06-22T18:56:19 < zippe>                                         RCC_CFGR_PLLMULL));
2012-06-22T18:56:20 < dongs> there's nothing in stm32f10x.h that uses HSE_VALUE acutally
2012-06-22T18:56:24 < zippe> That is some elegant shit right there.
2012-06-22T18:56:38 < dongs> haha
2012-06-22T18:57:34 < zippe> dongs: if you set the MCO to output HSE, and configure the GPIO for fast edges, do you get something sensible?
2012-06-22T18:57:44 < dongs> yes
2012-06-22T18:58:19 < dongs> HSE = i get 12mhz-lookin shit
2012-06-22T18:58:47 < dongs> it looks kinda... fucked but still 12mhz
2012-06-22T18:58:57 < zippe> Ok, and that waveform you linked for pll/2 looks like 72MHz / 2
2012-06-22T18:59:09 < dongs> ya
2012-06-22T18:59:29 < dongs> http://i.imgur.com/ACWVS.png < HSE
2012-06-22T18:59:32 < zippe> And code runs, so I think your PLL config is fine (should have looked at the wave first)
2012-06-22T19:00:09 < zippe> Yeah, you probably have no probe ground?  That just looks like it's ringing to shot
2012-06-22T19:00:38 < dongs> youre always right as usual
2012-06-22T19:01:11 < zippe> ha!  funniest thing I'll hear all day
2012-06-22T19:02:11 < dongs> so with my current config system_clock = 72... ext_osc = 12mhz, PLL/2 = 36mhz
2012-06-22T19:02:38 < dongs> if im getting USB interrupts, does that mean USB Shit is working?
2012-06-22T19:02:45 < dongs> if it was wrong clock, would I be geting htem?
2012-06-22T19:02:49 < zippe> Probably not
2012-06-22T19:03:38 < zippe> USB prescaler is probably set to /1.5 to get 48MHz from your 72MHz PLL output
2012-06-22T19:03:42 < dongs> right
2012-06-22T19:04:07 < Laurenceb> how much timing error can usb line with?
2012-06-22T19:04:11 < Laurenceb> *live
2012-06-22T19:04:55 < dongs> ok... without the pll * 6 change,, yeah, MCO outputs PLLCLK/2 as 54mhz
2012-06-22T19:05:08 < dongs> wiht PLL * 9 that is
2012-06-22T19:05:42 < dongs> 108mhz for sysclk
2012-06-22T19:06:01 < zippe> Laurenceb: tired brain says maybe 1% or so
2012-06-22T19:06:19 < zippe> dongs: F100 overclocks very nicely
2012-06-22T19:06:25 < zippe> Ran one over 50MHz
2012-06-22T19:06:31 < zippe> got a bit warm...
2012-06-22T19:06:59 < dongs> hmm now my pll/2 is 72mhz
2012-06-22T19:07:03 < Laurenceb> i have 0.14% error
2012-06-22T19:07:05 < dongs> hclk = 144
2012-06-22T19:07:28 < zippe> You can't do USB like that, sadly, not enough bits in the prescaler
2012-06-22T19:08:09 < zippe> Is your delay still hosed?
2012-06-22T19:09:24 < dongs> pll_12 is the max it will go before letting smoke out
2012-06-22T19:09:30 < dongs> so ya 144mhz
2012-06-22T19:09:59 < Laurenceb> "ChibiOS/RT Shell
2012-06-22T19:09:59 < Laurenceb> ch>
2012-06-22T19:09:59 < Laurenceb> "
2012-06-22T19:10:03 < Laurenceb> HELL YEAH
2012-06-22T19:11:29 < dongs> ok well, pll is fine, usbclk seems ot be fine
2012-06-22T19:11:35 < dongs> shit should work.
2012-06-22T19:11:36 < dongs> but its not
2012-06-22T19:15:06 < zippe> How does your delay function work?
2012-06-22T19:15:13 < dongs> its YOUR delay function :)
2012-06-22T19:15:25 < dongs> < dongs> http://bcas.tv/paste/results/oflprw26.html direct rip from OP, seems to be written by zippe
2012-06-22T19:15:57 < zippe> Ah, that one, got ripped up by the OP guys that didn't like my math
2012-06-22T19:16:11 < zippe> what's your us_ticks number?
2012-06-22T19:16:18 < zippe> I would expect 72
2012-06-22T19:16:20 < dongs> us_ticks = clocks.SYSCLK_Frequency / 1000000;
2012-06-22T19:16:22 < dongs> yes
2012-06-22T19:17:37 < dongs> thing is, i was dicking with changing RCC editors while shit was running, and I made that delay go to 16.5us when told to do 100us
2012-06-22T19:17:51 < dongs> er, ignore 'editors'
2012-06-22T19:17:56 < dongs> perhaps replce with'registers'
2012-06-22T19:17:58 < zippe> You are running the code that enables tracing, yes?
2012-06-22T19:18:01 < dongs> but i cant duplicate it agian :(
2012-06-22T19:18:11 < dongs> i shoulda screneshotted the regs
2012-06-22T19:18:16 < dongs> enables tracing?
2012-06-22T19:26:28 < dongs> I get RESET istr on connect..

2012-06-22T19:36:43 < zippe> sorry, got dragged off by a naked woman
2012-06-22T19:36:51 < zippe> You said that screwing with your debugger changed things
2012-06-22T19:37:02 < zippe> Maybe it's dicking with DWT_TRCENA
2012-06-22T19:37:18 < zippe> That timer function depends on the trace-enable bit being set to unlock the cycle counter
2012-06-22T19:37:27 < zippe>         (*(volatile unsigned long *)0xe000edfc) |= (1<<24);      /* DEMCR |= DEMCR_TRCENA */

2012-06-22T19:37:28 < zippe>         time = (*(volatile unsigned long *)0xe0001004)
2012-06-22T19:37:34 < dongs> oh right
2012-06-22T19:37:37 < dongs> but no
2012-06-22T19:37:40 < dongs> thats not in rcc shit gui
2012-06-22T19:37:43 < zippe> sorry, DMECR_
2012-06-22T19:37:54 < dongs> yeah, i know. the shit that isn't defined in cm3
2012-06-22T19:38:02 < zippe> No, but your debugger has to set TRCENA before it can do many things
2012-06-22T19:38:06 < dongs> ah
2012-06-22T19:38:08 < zippe> Most of them just set it and leave it
2012-06-22T19:38:15 < zippe> But yours might be re-setting it to be "helpful"
2012-06-22T19:38:19 < dongs> hehe
2012-06-22T19:38:43 < zippe> So it's worth checking that time works right for you with the debugger disconnected

2012-06-22T19:42:05 < Rickta59> and I find some code that is supposed to output the MCO
2012-06-22T19:42:34 < Rickta59> however the defines don't match up .. I thought the whole point of CMSIS was that you could switch processors and bingo bango it works

2012-06-22T19:44:06 < dongs> it worked
2012-06-22T19:44:15 < zippe> Rickta59: The MCO is not part of the architecture
2012-06-22T19:44:28 < Rickta59> isn;t it part of CMSIS?
2012-06-22T19:44:32 < zippe> No
2012-06-22T19:44:40 < Rickta59> or is that not portable between processors
2012-06-22T19:44:41 < dongs> i'd imagine MCO is st-specific
2012-06-22T19:44:46 < zippe> That's what I said
2012-06-22T19:44:55 < zippe> ARM are very definite about "the architecture"

2012-06-22T19:45:06 < dongs> ok USB hid works
2012-06-22T19:45:09 < zippe> If you haven't downloaded and read DDI0403C, you should.
2012-06-22T19:45:43 < zippe> Understanding "the architecture" vs. "the implementation" vs. "the SoC" will help you a lot
2012-06-22T19:45:53 < zippe> and now, 280.  Joy.
2012-06-22T19:46:00 < Rickta59> so if i'm using an m0 i should be looking at the V6 version of that?

2012-06-23T03:35:34 < dongs> cuz in the descritor it says cust0m (if you read the part of unicode crap)
2012-06-23T03:36:05 < dongs> 2011/09/25 < yes very old
2012-06-23T03:36:50 < Thorn> that usb driver is a HUGE MESS, also about half of it has leaked into the examples
2012-06-23T03:37:03 < dongs> ya it is horrible
2012-06-23T03:37:10 < dongs> what sucks about their sutff is like...
2012-06-23T03:37:14 < dongs> there is no docs of how to actually use it
2012-06-23T03:37:17 < dongs> the usb_lib shit
2012-06-23T03:37:29 < dongs> OK: here's examples, just copypaste more and perpetuate fail
2012-06-23T03:37:43 < dongs> UM0424 or whatever is basically useless.
2012-06-23T03:38:00 < Thorn> however, gdb from the latest codesourcery toolchain correctly prints backtrace even when control in an interrupt handler
2012-06-23T03:38:16 < Thorn> +is
2012-06-23T03:38:26 < dongs> what does it print it as? the code before hitting interrupt?
2012-06-23T03:39:16 < Thorn> something like that
2012-06-23T03:42:56 < Thorn> why are endpoint callbacks called in the driver but everything else like RESET_Callback() etc is dispatched in user code?
2012-06-23T03:43:05 < Thorn> etc.

2012-06-23T04:01:59 < szczys> okay, this is going to happen. I'm not getting up until I get this SPI running
2012-06-23T04:07:34 < Thorn> SPI? SPI is easy
2012-06-23T04:10:38 < dongs> thorn, why were you dicking with custom hid sample anyway
2012-06-23T04:10:45 < dongs> thats like same shit I finally got running yesterday :)
2012-06-23T04:12:14 < Thorn> * Function Name  : EP1_IN_Callback.
2012-06-23T04:12:15 < Thorn> * Description    : EP1 IN Callback Routine.
2012-06-23T04:12:33 < Thorn> extremely helpful
2012-06-23T04:12:35 < dongs> yeah.
2012-06-23T04:12:59 < Thorn> you can guess from the program logic that it's called after the transfer is complete
2012-06-23T04:15:27 < Thorn> Write the descriptor through the endpoint   <--- WAT
2012-06-23T04:15:58 < Thorn> I want to try hidapi, dekar said it was great. that's why custom hid
2012-06-23T04:17:53 < szczys> Thorn: SPI is easy if you don't us the STM peripheral library
2012-06-23T04:17:57 < szczys> but this library is a MESSS
2012-06-23T04:18:01 < dongs> uh...
2012-06-23T04:18:08 < szczys> finally got through everything and hooked it up... nothing
2012-06-23T04:18:09 < dongs> SPI is fine wiht peripheral library
2012-06-23T04:18:19 < dongs> oyoure doing it wrong
2012-06-23T04:18:27 < szczys> thanks Captain Obvious
2012-06-23T04:18:40 < szczys> but which part is wrong?
2012-06-23T04:18:56 < Thorn> the SPI part.
2012-06-23T04:19:12 < Thorn> I can pastebin some of my code that uses spi
2012-06-23T04:19:30 < szczys> That'd be great
2012-06-23T04:19:35 < szczys> the DMA example seems over complicated
2012-06-23T04:19:52 < szczys> I still think I could get it running in 10 minutes or so if I just wrote the register directly
2012-06-23T04:19:57 < szczys> but whatevs
2012-06-23T04:20:44 < dongs> i was driving a TFT display wiht SPI few months back
2012-06-23T04:20:51 < dongs> wiht like 5 minutes of hacking around
2012-06-23T04:21:01 < szczys> I'm trying to take this code and use hardware SPI instead:
2012-06-23T04:21:03 < szczys> http://pastebin.com/U1jNkXqL
2012-06-23T04:21:22 < szczys> So with the command bit being most significant I figure this is basically just 9-bit spi
2012-06-23T04:21:30 < Thorn> http://pastebin.com/urzD6MUS
2012-06-23T04:21:57 < Thorn> look for nrf_init(), spi_transfer(), spi_transfer_byte()
2012-06-23T04:22:01 < szczys> after I get SPI configured I want to replace the function with this:
2012-06-23T04:22:02 < szczys> 	uint16_t thisData = (uint16_t)Data;
2012-06-23T04:22:03 < szczys> 	if (isCmd) thisData |= 1<<8;
2012-06-23T04:22:03 < szczys> 	SPI_I2S_SendData16(SPIx, thisData);
2012-06-23T04:24:21 < zippe> szczys: I keep telling you, don't use the ST Library
2012-06-23T04:24:29 < szczys> yes, I know
2012-06-23T04:24:36 < szczys> but I want to give it a try anyway and learn for myself
2012-06-23T04:24:37 < dongs> did you scope the bus to see if youre doing it wrong?
2012-06-23T04:24:38 < zippe> If you can GPL your shit, use libopencm3 and beat on the #libopencm3 people to fix it
2012-06-23T04:24:50 < dongs> zippe, i thought cm3 was lgpl now
2012-06-23T04:24:51 < szczys> I don't possess a scope or a logic sniffer
2012-06-23T04:24:57 < szczys> (this makes things a bit harder)
2012-06-23T04:24:58 < dongs> szczys: then youre in the wrong hobby
2012-06-23T04:24:59 < zippe> dongs: yes, sorry
2012-06-23T04:25:02 < szczys> heh
2012-06-23T04:25:09 < zippe> I don't tend to think of the two as separate
2012-06-23T04:25:19 < szczys> scopes and logic sniffers?
2012-06-23T04:25:33 < szczys> I suppose a logic sniffers is the poor-man's scope
2012-06-23T04:25:40 < szczys> it would probably work in this case
2012-06-23T04:25:42 < zippe> szczys: cheap rigol = useful
2012-06-23T04:25:46 < dongs> no
2012-06-23T04:25:52 < dongs> cheap equipment = you'll pay again later.
2012-06-23T04:25:54 < szczys> yeah but a cheap rigol is still going to run around $300
2012-06-23T04:26:02 < Thorn> wat, libopencm3 is GPL? (lgpl is the same in firmware due to the lack of dynamic linking, right?)
2012-06-23T04:26:17 < cjbaird> LGPL3 now
2012-06-23T04:26:20 < dongs> Lpgl is = do whatever teh fuck you want including using in commercial shit
2012-06-23T04:26:22 < szczys> Thorn: thanks for posting that example
2012-06-23T04:26:27 < zippe> dongs: normally I'd agree, but the rigol is good enough that I think it doesn't count
2012-06-23T04:26:32 < szczys> I see I've forgotten to set the mode and perhaps that matters
2012-06-23T04:26:38 < zippe> lgpl = you must ship the source to the library
2012-06-23T04:27:01 < zippe> lgpl3 = some restrictions on what you can do with your system if you link this
2012-06-23T04:27:19 < cjbaird> ..and your mods to the library, but not anything in your code needed to make it work with the library
2012-06-23T04:27:38 < zippe> dongs: we have some truly hardcore gear at work, so I do have something of a benchmark re: the rigol
2012-06-23T04:28:31 < Thorn> I had a solder bridge between clk and miso (or was it mosi?) of a dataflash chip on one of the boards I'm currently hacking. I wonder what I'd do without my rigol.
2012-06-23T04:28:33 < zippe> Until some intern f4rked it up I had a CPCI Tek scope/analyser chassis on the bench in my office
2012-06-23T04:29:11 < zippe> The rigol is so cheap it's basically at the hand tool level
2012-06-23T04:29:48 < zippe> szczys: it'll be the best $300 you ever spend, and that includes ten minutes with the chick in the champagne room
2012-06-23T04:30:55 < szczys> ha! Well, I'm a musician by trade so it's hard to justify that kind of price tag for a hobby
2012-06-23T04:31:15 < szczys> I'm not running SPI_Init() which pretty much explains why this isn't working
2012-06-23T04:31:21 < dongs> lo
2012-06-23T04:31:49 < Thorn> l
2012-06-23T04:32:59 < szczys> nope, still nadda
2012-06-23T04:33:08 < szczys> is it hardware, is it software?
2012-06-23T04:33:18 < szczys> so I should connect my serial data line to MOSI, correct?
2012-06-23T04:33:19 < dongs> seriously, poking in the dark wiht hardware = waste of time
2012-06-23T04:33:31 < szczys> I'm familiar with this, dongs
2012-06-23T04:33:38 < szczys> but I've really got no choice at this point
2012-06-23T04:33:57 < dongs> each time I go  to another office where idiots cant afford to get some test equipment and they show me something not working and im like "how hte fuck am I supposed to debug this shit"
2012-06-23T04:34:12 < szczys> sure... but I'm not an office
2012-06-23T04:34:39 < szczys> I promise you, if I do open an office a scope will be my first purchase ;-)
2012-06-23T04:35:14 < Thorn> you have to have a product for that, and you can't make one without tools
2012-06-23T04:35:43 < Thorn> unless you mean a private music teacher's office or something
2012-06-23T04:36:03 < dongs> private blogger
2012-06-23T04:36:14 < szczys> yep, I do both of those things
2012-06-23T04:36:18 < Thorn> I made a USB HID progress bar
2012-06-23T04:36:22 < szczys> plus three other jobs
2012-06-23T04:36:26 < dongs> Thorn: wat?
2012-06-23T04:36:30 < dongs> 'progress bar'?
2012-06-23T04:36:34 < dongs> on PC?
2012-06-23T04:36:36 < Thorn> yes
2012-06-23T04:36:46 < szczys> got a video or post about it?
2012-06-23T04:36:50 < dongs> i stopped yesterday when I got the shit booting
2012-06-23T04:36:52 < dongs> cuz it was 2 am.
2012-06-23T04:37:00 < Thorn> usb hid demonstrator from st has a widget to display an analog value
2012-06-23T04:37:13 < dongs> the customhid shite?
2012-06-23T04:37:35 < Thorn> I'm sending an increasing value in a loop, custom hid had an adc hooked up there

2012-06-23T04:39:20 < dongs> how hard is it to name shit into something human readable
2012-06-23T04:39:34 < dongs> hell even including document id like UM1234.pdf would make more sense
2012-06-23T04:39:36 < dongs> than a fucking number
2012-06-23T04:40:55 < Thorn> I rename every document I download from st.com

2012-06-23T04:47:03 < Thorn> what is the value of SPIx_CLK?
2012-06-23T04:47:13 < zippe> szczys: yeah, which SPI?
2012-06-23T04:47:19 < zippe> SPI1 is on APB2, SPI2+ are on APB1
2012-06-23T04:47:34 < zippe> Once again, screwed by ST's craptastic API
2012-06-23T04:47:43 < dongs> how is that screwed
2012-06-23T04:48:01 < zippe> dongs: why do I have to know which clock control register controls my peripheral?
2012-06-23T04:48:05 < szczys> sorry, let me roll the defines into that pastebin
2012-06-23T04:48:12 < zippe> The API should be "turn the clock for SPI1 on"
2012-06-23T04:48:15 < dongs> zippe, why shouldnt you
2012-06-23T04:48:27 < zippe> dongs: because the library could know it already
2012-06-23T04:48:39 < dongs> as opposed to directly twiddling registers and looking it up anyway?
2012-06-23T04:48:48 < zippe> dongs: exactly
2012-06-23T04:48:54 < szczys> Here it is with the defines as well: http://pastebin.com/ANVM1z4k
2012-06-23T04:49:00 < Thorn> you can easily do RCC_APB1PeriphClockCmd(RCC_APB1Periph_something, ENABLE);
2012-06-23T04:49:04 < zippe> Either give me an API that does something useful, or sod off
2012-06-23T04:49:04 < dongs> why do you keep using retarded ad-filled paste sites
2012-06-23T04:49:19 < Thorn> or rather RCC_APB2PeriphClockCmd(RCC_APB1Periph_something, ENABLE);
2012-06-23T04:49:35 < zippe> Thorn: right, and that does nothing useful
2012-06-23T04:49:38 < dongs> st lib has checks against that
2012-06-23T04:49:42 < szczys> what paste site do you prefer?
2012-06-23T04:49:50 < dongs> thats why they have a IS_APB_BLAH_PERIPHERAL() macro in there
2012-06-23T04:49:50 < zippe> dongs: it doesn't
2012-06-23T04:49:53 < dongs> does too
2012-06-23T04:50:02 < zippe> dongs: there are bit collisions between the registers
2012-06-23T04:50:08 < dongs>   assert_param(IS_RCC_AHB_PERIPH(RCC_AHBPeriph));
2012-06-23T04:50:14 < zippe> dongs: and nobody checks the results or enables assertions
2012-06-23T04:50:14 < dongs> ^ this shit
2012-06-23T04:50:18 < dongs> of course.
2012-06-23T04:50:25 < dongs> but the effort is there.
2012-06-23T04:50:40 < zippe> dongs: you call it effort, I call it stupid
2012-06-23T04:51:11 < zippe> this->turn_on_the_fucking_thing()
2012-06-23T04:51:21 < zippe> Anything conceptually more complex than that = fail.
2012-06-23T04:52:04 < zippe> szczys: stupid question, do you have the clock for GPIOA on?
2012-06-23T04:52:15 < Thorn> that assert may not always trigger, what if numerical values for different clocks are the same
2012-06-23T04:52:26 < zippe> szczys: You are probably going to have to step through the code until you find where it's hanging
2012-06-23T04:52:30 < dongs> Thorn: he already said that
2012-06-23T04:52:57 < Thorn> you need c++ and enums to check that at compile time
2012-06-23T04:53:09 < zippe> Oh, this is awesome.  It looks like maybe the mplab compiler has hardcoded builtins for printf and friends.
2012-06-23T04:53:12 < cjbaird> dpaste.org has the least junk and busted html imho
2012-06-23T04:53:25 < dongs> whats wrong wiht bcas.tv/paste
2012-06-23T04:53:34 < szczys> zippe: holy cow!
2012-06-23T04:53:42 < szczys> I had been running this from software
2012-06-23T04:53:49 < szczys> and using the PortC pins
2012-06-23T04:53:57 < szczys> when I moved to PortA I never turned the clock for them on
2012-06-23T04:54:08 < zippe> Heh.  See above inre: screwed.
2012-06-23T04:54:19 < szczys> would that make this function hang though?
2012-06-23T04:54:21 < zippe> I would rather shave with a broken beer bottle than use that library
2012-06-23T04:54:30 < zippe> Yes, if you touch a peripheral whose clock is off, you will hang
2012-06-23T04:54:32 < szczys> zippe: liar
2012-06-23T04:54:40 < cjbaird> done that: "shave with a broken beer bottle"
2012-06-23T04:54:40 < szczys> good to know

2012-06-23T04:58:41 < szczys> hmmm... still not working but it's also no longer hanging
2012-06-23T04:59:06 < szczys> I might need to hook up a shift register and see what's coming out of this
2012-06-23T04:59:15 < szczys> that's the super-poor-man's scope
2012-06-23T04:59:57 < zippe> cjbaird: still not a fan of TNT
2012-06-23T05:00:11 < zippe> cjbaird: but if someone fixes the multilibs, maybe.
2012-06-23T05:04:15 < cjbaird> You're waiting on working hardfloat too, I take it. :)
2012-06-23T05:11:29 < dongs> hardfloat works in crossworks, and they use gcc
2012-06-23T05:11:33 < dongs> are you saying closedsores > opensores?
2012-06-23T05:13:05 < zippe> cjbaird: no, I have working hardfloat
2012-06-23T05:13:44 < zippe> cjbaird: But on gcc-4.6.x using the ARM bare-metal toolchain, which is a canned version of the GCC-EMBEDDED branch
2012-06-23T05:14:06 < zippe> TNT is using Linaro, which targets v7A, rather than v7M/v7R
2012-06-23T05:14:20 < zippe> But it's also tracking current 4.7.x
2012-06-23T05:14:38 < zippe> I'd like to see what the tradeoffs are really like.
2012-06-23T05:14:57 < zippe> I'm happy with the codegen stability of the ARM toolchain, but I'm a hopeless tinkerer. 8)
2012-06-23T05:15:32 < zippe> dongs: if someone was going to pay me to do it, I would write the multilib configs
2012-06-23T05:15:54 < zippe> dongs: or I would pass 30% of it plus a couple of beers off to an intern and they could do it
2012-06-23T05:16:11 < zippe> I did it once for SAT, but not making that mistake again

2012-06-23T05:16:50 < dongs> oh.
2012-06-23T05:16:53 < dongs> had to read what multilibs is
2012-06-23T05:17:07 < zippe> yeah, so basically if you use anything called *printf* and you compile it with the xc32 compiler from Microchip, count on the compiler emitting a random selection of references to functions in their C library.  Even if you disable builtins.
2012-06-23T05:17:11 < dongs> basically same lib built either with soft or hard float
2012-06-23T05:17:13 < dongs> or whatever?
2012-06-23T05:17:21 < zyp> dongs, or for different archs
2012-06-23T05:17:32 < zippe> dongs: It's how gcc handles support for more than one ABI
2012-06-23T05:17:50 < zyp> zippe, or architectures
2012-06-23T05:18:08 < zippe> dongs: rather than having N completely different compilers which are 99% the same, you have one compiler and then there is magic that works out, based on the commandline options, which libraries should be linked.
2012-06-23T05:18:21 < zippe> zyp: or ISA, yes.
2012-06-23T05:22:06 < Thorn> my hid device responds to IN requests to turn leds on/off from the hid demonstrator. it displays "led on/off" on the lcd.

2012-06-23T06:54:21 < zippe> No, it stinks
2012-06-23T06:54:31 < dongs> what really.
2012-06-23T06:54:37 < zippe> Most SoC vendors haven't reworked their peripherals to do useful things with single-bit changes
2012-06-23T06:55:20 < dongs> but its useful for gpio!
2012-06-23T06:55:44 < zippe> Better to have set/clear register pairs for GPIO data
2012-06-23T06:55:47 < szczys> I'm still working on this SPI
2012-06-23T06:55:56 < szczys> using a Bus Pirate to sniff the communications
2012-06-23T06:56:01 < szczys> I'm getting the right number of bytes
2012-06-23T06:56:06 < szczys> but they're all 0x00
2012-06-23T06:56:13 < zippe> szczys: OLS probably works with the BP these days
2012-06-23T06:56:18 < szczys> so something's not working right on the MOSI
2012-06-23T06:56:24 < szczys> OLS?
2012-06-23T06:56:35 < zippe> Open Logic Sniffer (client)
2012-06-23T06:56:52 < szczys> oh yes, I think you're right
2012-06-23T07:03:42 < szczys> Are there any obvious reasons I wouldn't be getting data out of the MOSI pin?
2012-06-23T07:06:54 < zippe> GPIO config bad
2012-06-23T07:07:05 < zippe> Not writing to the data register
2012-06-23T07:08:57 < szczys> eh...
2012-06-23T07:09:04 < szczys> looks like my data is bad
2012-06-23T07:09:14 < szczys> I just tried sending 0x01FF and that seems to work
2012-06-23T07:15:49 < szczys> This is strange
2012-06-23T07:16:11 < szczys> I'm getting the data I would expect, except that there are two extra bits at the beginning of the transmission
2012-06-23T07:16:18 < szczys> both 0
2012-06-23T07:16:31 < szczys> so instead of 0x80
2012-06-23T07:16:37 < szczys> the first byte is 0x20
2012-06-23T07:16:46 < szczys> like everything's shifted right by two bytes

2012-06-23T12:14:54 <+Steffanx> cursor keys => characters .. fixed it partially, but it still fails sometimes
2012-06-23T12:15:22 <+Steffanx> Anyway, you use notepad.exe so you are not allowed to speak :P
2012-06-23T12:21:30 < dongs> Thorn: whats the plan of action then
2012-06-23T12:21:37 < dongs> is there any clean USB code for stm32 lol
2012-06-23T12:21:54 < dongs> I think libmaple is more or less same shit except they used even older usblib where they used shit like u8/u16 for types
2012-06-23T12:21:58 < dongs> so it fails even more
2012-06-23T12:22:04 < Thorn> libopencm3 has a driver, it's much better but completely undocumented iirc
2012-06-23T12:22:12 < dongs> oh, libopencm3 right
2012-06-23T12:22:13 <+Steffanx> u8/u16 isn't that linux style?
2012-06-23T12:25:21 < dongs> thorn, there's some examples
2012-06-23T12:25:34 < dongs> i.e. libopencm3\examples\stm32\f1\lisa-m\usb_hid
2012-06-23T12:25:57 < dongs> static const u8 hid_report_descriptor[] = {
2012-06-23T12:26:03 < dongs>  /* I have no idea what this means. I haven't read the HID spec. */
2012-06-23T12:26:04 < Thorn> the examples I've seen called usb_poll() or something in a loop
2012-06-23T12:26:04 < dongs> loill
2012-06-23T12:26:30 < Thorn> at least the st driver is fully interrupt driven
2012-06-23T12:27:01 < dongs>  while (1) usbd_poll();
2012-06-23T12:27:03 < dongs> yeah.
2012-06-23T12:27:09 < dongs> looks great
2012-06-23T12:35:56 < dongs> well shit
2012-06-23T12:49:46 < dongs> ugh
2012-06-23T12:49:56 < dongs> usb_prop.c under USER_STANDARD_REQUESTS
2012-06-23T12:49:57 < dongs> so retarded
2012-06-23T12:50:10 < dongs> #define CUSTOMHID_GetConfiguration NOP_Process
2012-06-23T12:50:17 < dongs> why not just ufcking put NOP_Process in the struct???
2012-06-23T12:50:23 < dongs> instead of having to look in2 places for it
2012-06-23T12:50:35 < dongs> and guess if its a define or a function or wat
2012-06-23T12:50:36 < dongs> rage.
2012-06-23T12:55:08 < Thorn> #define  EP2_IN_Callback   NOP_Process, etc.
2012-06-23T12:55:23 < Thorn> there're null pointers you know
2012-06-23T12:55:34 < Thorn> if(callbacks[i]) callbacks[i]();
2012-06-23T12:58:03 < dongs> yeah
2012-06-23T13:00:00 < dongs> wait , the fuck
2012-06-23T13:00:04 < dongs> nop_process is empty function
2012-06-23T13:00:15 < dongs> i thoguth it was a #define NULL or somehtign
2012-06-23T13:00:22 < Thorn> lol.
2012-06-23T13:02:49 < Thorn> they probably thought they saved cycles by not having to test function pointers for zero

2012-06-23T15:39:15 <+Steffanx> Time for a nap mr dongs
2012-06-23T15:55:16 < cjbaird> Aha! I've found what the mysterious 92ohm resistance between GND and 5V is on the BBII: there's a SIP resistance network of 6x 220/330 "550R" resistors between gnd and vcc. 6x || 550R = ~92..  Testing with IR detector... yep, that's where all the power is going through.

2012-06-23T16:00:06 < cjbaird> Going over the schematic has given me even more appreciation for the skillz that Steve Woz had.. The AppleII was a far better designed system than this..
2012-06-23T16:00:24 < cjbaird> dogs: truth
2012-06-23T16:03:53 < cjbaird> This Z80 board has 105 ICs on it.. The A2 did a better job in 30.

2012-06-23T16:08:43 <+Steffanx> *+from
2012-06-23T16:17:14 < cjbaird> I expect the AppleIIe series machines used CAD tools, but the original A2 PCB (and this BBII) was definitely done by hand. Not easy tasks. And even then, the boards that size weren't any cheaper to make than today.
2012-06-23T16:18:28 < dongs> $200 in 1985 money was a lot
2012-06-23T16:18:54 < dongs> You can condense an entire crappleII into a 10x10mm FPGA today
2012-06-23T16:18:59 < dongs> and a bunch of peripherals
2012-06-23T16:19:10 < cjbaird> The BBII bare-board kit, without chips, cost 1985 US$295...
2012-06-23T16:19:11 < dongs> so PCB cost wouldn't be so high :p
2012-06-23T16:19:21 < dongs> ouch
2012-06-23T16:19:33 < dongs> and people complain when china charges $10 for 10 shitty pcbs with silkscreen and mask :)
2012-06-23T16:21:13 <+Steffanx> shitty pcbs?!?!?!?!?!?!?!
2012-06-23T16:21:29 < cjbaird> I recall the original Apple1 PCBs cost 1976 US$75 to make, which the Steves sold with a $50 margin. Fully-build A1 sold for $666
2012-06-23T16:21:59 < dongs> fucking steve, never lost a penny. dumb users just lapped his shit up

2012-06-23T16:24:21 < cjbaird> Jack Tramel's standard formula for selling computers was to make them for $N, sell them to dealers for $2N, who then sold them to customers for $4N.. The original C64 model cost ~$150 to make (at first), and it retailed for $599..

2012-06-23T18:04:27 < zyp> well, I'm in the top floor of the hotel, but I guess there is still too much shit above me
2012-06-23T18:04:34 < BrainDamage> I mean, you can get time from a single sat
2012-06-23T18:04:57 < BrainDamage> which explains why you can get time but no fix
2012-06-23T18:05:21 < zyp> yep
2012-06-23T18:05:41 < zyp> I didn't say that I didn't understand why I got only time
2012-06-23T18:06:12 < Tectu> Steffann, still arround?

2012-06-23T18:07:39 < zyp> it's been in the mid twenties in tokyo lately

2012-06-23T18:08:10 <+Steffann> they expect less coming week
2012-06-23T18:08:39 < Tectu> Steffann, sounds lovely. I hate everything about 20°C
2012-06-23T18:08:48 < Tectu> and here in switzerland, you have over 30°C all day in summer
2012-06-23T18:08:49 < zyp> was a typhoon here a few days ago

2012-06-23T18:14:40 < Tectu> how about all these double vocals, sir?
2012-06-23T18:14:52 <+Steffann> double?
2012-06-23T18:14:54 < Tectu> written dutch looks like someone faceroll'd his keyboard
2012-06-23T18:14:58 < Tectu> like   oo and aa etc
2012-06-23T18:15:12 <+Steffann> Kaas vs cheese .. don't see the difference :P
2012-06-23T18:15:19 < Tectu> that's not fair, sir :D
2012-06-23T18:15:33 < Tectu> double a and double o is just wrong
2012-06-23T18:16:11 <+Steffann> Or do you mean when you have multiple of them? Kaas => kazen and not kaazen? :)
2012-06-23T18:16:15 < zyp> foo
2012-06-23T18:16:20 <+Steffann> And the fancy z instead of s :)

2012-06-23T18:17:41 < Tectu> Steffann, well, I am not serious btw, I like to know any language. But dutch just seems to be a troll language :D

2012-06-23T20:27:39 < dongs> right
2012-06-23T20:27:52 < Rickta59> i'm not using any OS so I don't see how that would matter to me
2012-06-23T20:28:42 < Rickta59> do any of the opensource rtos projects use SVC?
2012-06-23T20:29:02 <+Steffann> Probably, yes
2012-06-23T20:30:06 < dongs> coos doesnt it seems.
2012-06-23T20:30:12 < dongs> NOT LEET ENOUGH i guess.
2012-06-23T20:30:47 <+Steffann> l33T
2012-06-23T20:31:00 < dongs> they use PendSV
2012-06-23T20:32:44 < dongs> so far this shitty HID code is 8kbytes  compiled
2012-06-23T20:32:49 < dongs> and i dont even have any bootloader capability yet
2012-06-23T20:32:54 < dongs> ... that seems kinda gay.
2012-06-23T20:33:03 <+Steffann> 8kb :S
2012-06-23T20:33:30 < dongs> lemme see what it looks like with cross module optimizations
2012-06-23T20:33:37 < dongs> ok, 5.7k thats better
2012-06-23T20:33:39 < dongs> but still
2012-06-23T20:33:46 < dongs> isnt that a bit large for a bootlol'der
2012-06-23T20:33:52 <+Steffann> And that with your ArmCC compiler?!
2012-06-23T20:33:56 < dongs> yaman.
2012-06-23T20:34:15 <+Steffann> Must be a disappointment
2012-06-23T20:34:17 < dongs> yea

2012-06-23T21:49:19 < szczys> yay, I got my SPI working!
2012-06-23T21:49:46 < szczys> I had a series of things not going my way...
2012-06-23T21:49:47 < Rickta59> what did it turn out was the causing you issues
2012-06-23T21:50:01 < szczys> I had reversed the polarity of the command bit for the device I"m working with (Doh!)
2012-06-23T21:50:17 < szczys> That and a few of the setup functions which were not jiving
2012-06-23T21:50:18 < Rickta59> CPOL?
2012-06-23T21:50:24 < szczys> no, I had that right
2012-06-23T21:50:33 < szczys> but this is using 9-bit protcol
2012-06-23T21:50:42 < szczys> with the MSB signaling a command
2012-06-23T21:50:45 < Rickta59> that is kind of strange
2012-06-23T21:50:48 < szczys> (versus just plain data)
2012-06-23T21:50:54 < Rickta59> does the hw support non 8 bit spi?
2012-06-23T21:50:57 < szczys> but that command bit is low for a command, and high for data
2012-06-23T21:51:00 < szczys> yes
2012-06-23T21:51:08 < szczys> 4-14 bits I think
2012-06-23T21:51:11 < Rickta59> i mean natively .. or did you have to slice it
2012-06-23T21:51:12 < Rickta59> k
2012-06-23T21:51:13 < szczys> that's why I chose to do this one
2012-06-23T21:51:24 < szczys> since I couldn't do 9-bit hardware SPI with AVR chips
2012-06-23T21:51:38 < Rickta59> some of the 430 chips have 16 bit spi .. kind of handy
2012-06-23T21:51:52 < szczys> anyone know what the NSS signal is used for?
2012-06-23T21:52:05 < szczys> I've read about it in the reference manual, but am confused on how it works
2012-06-23T21:52:16 < szczys> I'd like to use it to drive the CS bit on this SPI device
2012-06-23T21:52:28 < szczys> but that was one of the things preventing thing from working
2012-06-23T21:52:37 < szczys> I ended up just grounding it for now
2012-06-23T21:53:00 < szczys> but I think that's a bad idea, just in case I a comm gets interrupted and has to start over again
2012-06-23T21:53:19 < Rickta59> can't you use any pin to do that if you can't figure out NSS
2012-06-23T21:53:53 < Rickta59> i think NSS is just another name for chip select
2012-06-23T21:54:27 < Rickta59> a quite from my.st.com "The NSS on the STM32 doens't act as a chip select thant can be used to synchronize the data exchange operations.
2012-06-23T21:54:27 < Rickta59> The datasheet isn't clear and already has some errata but still not clear."
2012-06-23T21:54:46 < Rickta59> so maybe you just need to use another GPIO pin for chip select
2012-06-23T21:55:06 < szczys> yeah... I read that post too
2012-06-23T21:55:28 < szczys> but in the datasheet it says something about NSS driving low whenever SPI is enabled... etc.
2012-06-23T21:55:43 < szczys> But maybe it's only used when the chip needs to switch between master and slave
2012-06-23T21:56:10 < szczys> I'd like to have an understanding of *why* I'm not going to be able to use it
2012-06-23T21:57:09 < szczys> further down in the thread it suggests that I drive the pin low manually, then use the TXNE flag interrupt to set it high again
2012-06-23T21:57:33 < Rickta59> once you are talking to the device do you ever let go of it?
2012-06-23T21:57:40 < Rickta59> you are talking to a display?
2012-06-23T21:57:40 < szczys> no
2012-06-23T21:57:45 < szczys> yes, it's a display
2012-06-23T21:58:14 < Rickta59> seems like just using a gpio so you can coordinate when it starts seems reasonable .. where were you reading about the use of that flag? * I'
2012-06-23T21:58:27 < Rickta59> m still trying to figure what data sheets and app notes i need to get
2012-06-23T21:58:27 < szczys> is there any concern that I might get out of sync with the receiver?
2012-06-23T21:58:38 < szczys> and is that what the CS is meant for? Syncing the transmissions?
2012-06-23T21:59:05 < Rickta59> CS is chip select ... it is most useful with you have multiple devices on an SPI bus you want to address
2012-06-23T21:59:18 < Rickta59> so you had an SPI display and also wanted to talk to an SD card
2012-06-23T21:59:31 < szczys> I use the reference manual RM0091
2012-06-23T21:59:33 < Rickta59> you could have them both wired to MISO/MOSI/MCLK
2012-06-23T21:59:47 < Rickta59> but you would have 2 chip select lines .. one for the display .. one for the sdcard
2012-06-23T22:00:01 < szczys> and the datasheet for STM32F05x devices
2012-06-23T22:00:13 < szczys> the datasheet has the pinouts for this chip
2012-06-23T22:00:20 < Rickta59> so to direct data in an out of the display you would drag the chip select low for the display
2012-06-23T22:00:31 < szczys> which is how I figured out which pins could be MSOI, CLK, etc.
2012-06-23T22:00:33 < Rickta59> then send spi command that it knows about
2012-06-23T22:00:46 < Rickta59> and the you could let go and then drag the sd card low
2012-06-23T22:00:51 < Rickta59> and talk to it
2012-06-23T22:01:11 < Rickta59> usually when you do a CS the device will get itself into a know state
2012-06-23T22:01:30 < Rickta59> and when you let go it will ignore MOSI data
2012-06-23T22:01:34 < szczys> right
2012-06-23T22:01:36 < Rickta59> and not produce any data on MISO
2012-06-23T22:01:57 < szczys> this display has no MISO
2012-06-23T22:02:08 < Rickta59> sure .. that seems normal
2012-06-23T22:02:34 < szczys> boy, I just love that SysTick feature
2012-06-23T22:02:42 < szczys> what a fantastically useful thing to have
2012-06-23T22:02:47 < Rickta59> do you know what the doc # for the RM0091 is?
2012-06-23T22:03:03 < szczys> hmmm... no but I can find you a link really quick
2012-06-23T22:03:32 < Rickta59> i'm in linux so it doesn't preview the doc .. and i have downloaded like 20 of them
2012-06-23T22:03:47 < Rickta59> but none of the rm numbers match the filenames
2012-06-23T22:04:07 < Rickta59> i should just rename them

2012-06-23T22:04:49 < Rickta59> right thanks
2012-06-23T22:04:50 < szczys> (DM00031936)
2012-06-23T22:05:33 < Rickta59> that makes sense .. call rm 91 some other #
2012-06-23T22:06:07 < Rickta59> how fast are you driving the display?
2012-06-23T22:06:18 < Rickta59> this is that color nokia one?
2012-06-23T22:08:28 < szczys> yep
2012-06-23T22:08:38 < szczys> Let's see... I'm using prescaler of 4
2012-06-23T22:08:40 < szczys> so 12 MHz
2012-06-23T22:08:59 < Rickta59> nice, you can pump in a lot of data @ 12MHz
2012-06-23T22:09:49 < Rickta59> page 639
2012-06-23T22:10:06 < Rickta59> they are showing a gpio connected to the slaves CS pin
2012-06-23T22:10:37 < Rickta59> looks like NSS is a slave mode feature not a master
2012-06-23T22:11:30 < szczys> "In master mode, NSS can be used either as output or input.
2012-06-23T22:11:30 < szczys> As an input it can prevent multimaster bus collision, and as an output it can drive a slave
2012-06-23T22:11:30 < szczys> select signal of a single slave.
2012-06-23T22:11:30 < szczys> "
2012-06-23T22:11:39 < Rickta59> yeah i see that .. but
2012-06-23T22:11:58 < Rickta59> later if you want to add another spi device you could already have the right mindset using GPIO
2012-06-23T22:12:16 < Rickta59> but if you only ever have one SPI device on that bus I guess it would be OK
2012-06-23T22:12:52 < szczys> it's no big deal... I just like to learn as I go
2012-06-23T22:13:02 < szczys> and I see no reason why this wouldn't work in this case
2012-06-23T22:13:07 < szczys> Who knows?
2012-06-23T22:13:11 < Rickta59> so did you use HW? NSS
2012-06-23T22:13:20 < szczys> I think I might program the game snake to play on this hardware
2012-06-23T22:13:21 < Rickta59> with output enable
2012-06-23T22:13:34 < Rickta59> SSM=0, SSOE=1
2012-06-23T22:14:01 < szczys> I'm using the libraries, and I think I had it setup correctly for this... not sure
2012-06-23T22:14:07 < Rickta59> k ..
2012-06-23T22:14:24 < Rickta59> you might poke around int he library code to see if it is doing that
2012-06-23T22:15:27 < szczys> yeh... now that I've got it working (with CS tied to ground) I'll give it another go and see what I can come up with.
2012-06-23T22:15:36 < szczys> I would also like to use the watchdog
2012-06-23T22:15:51 < Rickta59> * looking at code ..
2012-06-23T22:15:54 < szczys> since I'm blocking the code while I wait for the TX flag
2012-06-23T22:16:11 < Rickta59> doesn't seem like they use the same define names as the RM91 doc

2012-06-23T22:17:54 < Rickta59> are you using SPI_NSS_Hard?
2012-06-23T22:19:31 < Rickta59> hmm .. library doesn't mention SSOE .. only SSM
2012-06-23T22:20:16 < szczys> SPI_SSOutputCmd()
2012-06-23T22:20:22 < szczys> in the spi.c file
2012-06-23T22:20:45 < Rickta59> k ..
2012-06-23T22:20:54 < Rickta59> i was looking in the spi header not the stm32f0xx.h
2012-06-23T22:21:17 < Rickta59> looks like the default is hw if you use the spi init function
2012-06-23T22:22:05 < Rickta59>  Enable or disable the SS output using the SPI_SSOutputCmd() function .. so you are using this?
2012-06-23T22:23:22 < szczys> this is really weird
2012-06-23T22:23:31 < szczys> every other time I press reset the screen works/doesn't work
2012-06-23T22:23:38 < szczys> extremely reliable
2012-06-23T22:23:52 < Rickta59> maybe you are talking to it before it is ready
2012-06-23T22:24:07 < szczys> NSS has nothing to do with it
2012-06-23T22:24:15 < Rickta59> i mean powering off
2012-06-23T22:24:18 < Rickta59> and powering on
2012-06-23T22:24:26 < Rickta59> or are you just pressing reset
2012-06-23T22:24:28 < szczys> power on always works
2012-06-23T22:24:36 < szczys> just pressing reset causes the issue
2012-06-23T22:24:47 < Rickta59> and you have it tied low the NSS pin?
2012-06-23T22:25:18 < Rickta59> tied low as in you aren't toggling it with software
2012-06-23T22:26:21 < Rickta59> seems like you should probably pull it high and then low on reset
2012-06-23T22:30:52 < szczys> ah-ha
2012-06-23T22:30:58 < szczys> there's a reset pin
2012-06-23T22:31:06 < szczys> and this requires reset at the beginning of initialization
2012-06-23T22:31:24 < szczys> with the system clock running at 48 MHz it must be toggling too fast for the display to react to it
2012-06-23T22:31:44 < szczys> (or that skew rate is getting me.... slow pin response vs. fast clock)
2012-06-23T22:32:10 < szczys> I just added a 1ms delay between driving the reset line low, then high again
2012-06-23T22:32:14 < szczys> and that fixed it
2012-06-23T22:32:57 < Rickta59> so are you doing anything more with the template or you are just leaving it the way it is?
2012-06-23T22:36:24 < szczys> I'm still hoping to find (or code) a nice startup/linker pair
2012-06-23T22:36:35 < szczys> do you have any suggestions for additions/changes?
2012-06-23T22:36:37 < Rickta59> that startup code seems like you can use it
2012-06-23T22:36:52 < Rickta59> the copyright is by st not anyone else
2012-06-23T22:37:00 < szczys> true
2012-06-23T22:37:11 < szczys> but I think the linker has to catch all the stuff in the startup code
2012-06-23T22:37:23 < Rickta59> there is actually a lot of extra stuff in there
2012-06-23T22:37:29 < szczys> yep
2012-06-23T22:37:37 < Rickta59> i did comment out one of the calls in the startup code
2012-06-23T22:37:44 < szczys> which one?
2012-06-23T22:37:58 < Rickta59> to some init function my code didn't know about
2012-06-23T22:38:21 < Rickta59> * goes to look

2012-06-24T02:31:38 <+dekar> so I guess it should work on reactOS?

2012-06-24T15:55:18 < zyp> I picked up the L1 discovery today, so now I've got something new to play with when I have time
2012-06-24T15:56:06 < Thorn> is it the one with the lcd?
2012-06-24T15:56:43 < zyp> yep
2012-06-24T15:57:23 <+dekar> cjbaird, so has TNT compiled yet on that raspi? :)
2012-06-24T15:59:44 < Thorn> http://www.eis.mdx.ac.uk/research/PhDArea/saeed/paper1.pdf    "It has taken us some time to dare to believe in our own results. It now seems to us ... that what distinguishes the three groups in the first test is their different attitudes to meaninglessness."
2012-06-24T16:00:19 < cjbaird> dekar: yep :) .. It can build working executibles, too..
2012-06-24T16:01:38 < cjbaird> Thorn: yow, that'll piss a lot of invested interests off..
2012-06-24T16:02:04 < Tectu> guys, help me shifting!
2012-06-24T16:02:05 < Tectu> I fail at this:   when splitting a word into two bytes, where x is a word (uint16_t), i can do    x >> 8    to get the higher byte and   x & 0xFF to get the lower byte, right?
2012-06-24T16:02:22 < Thorn> right
2012-06-24T16:02:36 < Tectu> okay, now i want to split the word into four nibbles (a nibble is 4 bits)
2012-06-24T16:02:40 < Tectu> and i fail at that o0
2012-06-24T16:02:51 < Tectu> x >> 12    gives the highes nibble, right?
2012-06-24T16:03:17 < Tectu> (x >> 8) & 0x0F    does that give the second highest nibble?!
2012-06-24T16:03:34 < Thorn> yes and yes
2012-06-24T16:03:39 < zyp> yes
2012-06-24T16:03:48 < cjbaird> (x >>8 ) & 0xF0 >> 4
2012-06-24T16:03:50 < Tectu> so the third nibble is   (x >> 4) & 0x0F
2012-06-24T16:03:59 < Tectu> huch?
2012-06-24T16:04:08 < Tectu> cjbaird, ?
2012-06-24T16:04:15 < cjbaird> waitm half-asleep
2012-06-24T16:04:15 < zyp> basically, (x >> (n * 4)) & 0xf will give the n'th nibble where nibble 0 is the lowest
2012-06-24T16:04:30 < Tectu> ah!
2012-06-24T16:04:32 < Tectu> here we go
2012-06-24T16:04:43 < Tectu> i was searching for some "generic" macro for that
2012-06-24T16:04:46 < Tectu> thank you very much zyp
2012-06-24T16:05:00 < Tectu> damn, now where I see it, it is pretty easy ^^
2012-06-24T16:05:47 < Thorn> http://www.hackersdelight.org/basics.pdf
2012-06-24T16:07:28 < Tectu> does the compiler optimize  shift by zero  out?
2012-06-24T16:08:15 < Thorn> if the zero is known at compile time then yes
2012-06-24T16:09:49 < zyp> yes
2012-06-24T16:11:52 < Tectu> i try to write some "generic" function for GPIO bitbanging a 16-bit LCD... therfore i split the 16-bits into four 4 bit groups. Now the user should give the Port for each nibble, and the basepin (offset) of it... why does this not work?   http://pastebin.com/vsV8Yaes
2012-06-24T16:12:05 < cjbaird> "Overflow occurred iff c equals the high-order bit of s" .. whoa. When I was writing that 6502 sim, I had to calculate the overflow-status flag at one point (using the straight-forward method), and the GCC optimizer reduced the code into that. I thought something was wrong when I checked the assembly. :I
2012-06-24T16:12:44 < Tectu> this one works:   http://pastebin.com/h9bUsdQy
2012-06-24T16:12:51 < Tectu> that is just with two bytes, instead of four nibbles
2012-06-24T16:12:55 < dongs> Tectu: so fucking ugly. why dont you use bitbanding
2012-06-24T16:13:01 < zyp> Tectu, sounds dumb
2012-06-24T16:13:08 < Tectu> zyp, what do you mean?
2012-06-24T16:13:17 < zyp> why 4-bit nibbles?
2012-06-24T16:13:23 < dongs> 4bit niggles
2012-06-24T16:13:35 < zyp> why having subgroups at all?
2012-06-24T16:13:48 < Tectu> the problem is that not every board does have a full 16-bit free port. not even two full 8-bits on the most boards
2012-06-24T16:13:54 < Tectu> so i thought split it in four groups of four :)
2012-06-24T16:14:13 < Tectu> on f4 discovery you don't have even two 8-bit ports
2012-06-24T16:14:18 < Tectu> on the pinheaders
2012-06-24T16:14:27 < zyp> but why four? why not single pins?
2012-06-24T16:14:44 < Thorn> is byte addressing of gpio registers allowed?
2012-06-24T16:14:45 < Tectu> dunno, thought this might be the easiest way to configure for the user of the library
2012-06-24T16:15:07 < Tectu> zyp, writing 32 #defines is stupid too?!
2012-06-24T16:15:19 < Tectu> if you have any other idea, I'd be happy to hear it, of course
2012-06-24T16:16:13 < Tectu> but anyways, why dosen't the thing i pasted work?
2012-06-24T16:16:31 < zyp> well, I'd make some template shit taking a list of all 16 pins, then generating the most efficient code for the chosen pins by grouping pins on same port
2012-06-24T16:16:52 < Tectu> yeah, but that's not the priority atm.
2012-06-24T16:17:07 < Tectu> na c'mon, can't you just tell me why the four lines i wrote up dosen't work=?
2012-06-24T16:17:23 < zyp> haven't even looked at them
2012-06-24T16:17:36 < zyp> ok, I'll check
2012-06-24T16:17:39 < Tectu> thank you :)
2012-06-24T16:17:53 < zyp> because line 7 says 3 and not 4
2012-06-24T16:18:58 < Tectu> lol...
2012-06-24T16:19:26 < Tectu> hmm...
2012-06-24T16:19:56 < zyp> hang on, I spotted another, just checking
2012-06-24T16:19:59 < Tectu> could there by anything else wrong?
2012-06-24T16:20:02 < Tectu> aye
2012-06-24T16:20:41 < zyp> yep, bitshift has higher order of precedence than bitwise or
2012-06-24T16:20:54 < Tectu> aahè
2012-06-24T16:20:58 < zyp> so put parantheses around the or
2012-06-24T16:22:38 < Tectu> around the or? o0
2012-06-24T16:23:01 < Thorn> around the >> <<
2012-06-24T16:23:52 < Tectu> I really don't understand where you mean, Thorn
2012-06-24T16:27:46 < Thorn> you have foo = a | b << c;
2012-06-24T16:28:20 < Thorn> or rather for whatever reason foo = (a | b << c);
2012-06-24T16:28:51 < Thorn> you need foo = (a | b) << c;
2012-06-24T16:29:11 < zyp> what Thorn said

2012-06-24T17:40:03 < cjbaird> It's just a bit pattern of "1111" that'll be shifted over..
2012-06-24T17:40:24 < Tectu> ah, that makes sense indeed
2012-06-24T17:40:58 < cjbaird> 1 << 8 = 256; 3 << 8 = 768 (the "11" becomes 256+512)
2012-06-24T17:42:13 < Tectu> so   MASK(12)   ->  0xF000,   MASK(8) -> 0x0F00,    MASK(4) -> 0x00F0,   MASK(0) -> 0x000F     right?

2012-06-24T19:25:51 < monode> does the TIMx_ARR register act as an autoreload register for TIMx_CNT, so - for example, after an update event with ARR set at 512, CNT will become 512, or will the update event occur when CNT changes value to 511?
2012-06-24T19:27:24 < monode> does it act like the TOP value on avr timers being the point where the timer overflows, or does it act like a "bottom" value to be preloaded after the timer resets at 0xFFFF, and will always reset at 0xFFFF?
2012-06-24T19:29:19 < monode> I want to make a simple pulse frequency modulator on a timer, that is, have a high value on a PWM pin for a a fixed number of clocks, and have the pin at LOW for a varying amount of clocks.
2012-06-24T19:31:09 < monode> I think i'm supposed to use CCR as the trip point and ARR for the frequency, but the datasheet isn't very clear on ARR (or I'm not very good at understanding it). I think it's the first version - it acts as a TOP value
2012-06-24T19:32:20 < jpa-> it is top value
2012-06-24T19:33:00 < jpa-> timer freq = clock freq / (PSC + 1) / ARR
2012-06-24T19:33:21 < monode> yeah, was getting ready to paste this "In upcounting mode, the counter counts from 0 to the auto-reload value (content of the  TIMx_ARR register), then restarts from 0 and generates a counter overflow event."
2012-06-24T19:33:23 < jpa-> or was it ARR + 1 also
2012-06-24T19:34:51 < monode> oh, it's zero counting, so i assume that if you set ARR+1, you'd get ARR+2 counts.

2012-06-24T20:50:16 < philpem> could someone please have a look at my SPI driver code? http://pastebin.com/QZ0Y65YJ
2012-06-24T20:50:46 < philpem> if I reduce the prescaler from 128 to 16, it's fine, but if I go any lower I get lockups
2012-06-24T20:51:10 < philpem> usually when it's waiting for RXNE on the last received data block
2012-06-24T20:51:32 < philpem> (lines 90 and 151)
2012-06-24T21:04:49 < zyp> oh, karlp finally killed the texane examples, nice
2012-06-24T21:05:08 <+Steffanx> Free beer for karlp ?
2012-06-24T21:05:19 < zyp> well, a few days ago, but I haven't been following the activity here lately
2012-06-24T21:07:08 < philpem> hmm, looks like SPI_I2S_FLAG_RXNE is getting stuck low :(
2012-06-24T21:11:48 < zyp> so it gets stuck in the loop on line 68?
2012-06-24T21:12:20 < philpem> well, it gets stuck after it's finished sending data
2012-06-24T21:12:30 < philpem> so it sends the "N" bytes it has, reading the response byte every time
2012-06-24T21:13:09 < philpem> then when it tries to get the response to the final byte (which is the byte in the MRF24J40's register) RXNE stays low and it sticks on line 90 or 151
2012-06-24T21:13:17 < zyp> so, where in the code does it get stuck?
2012-06-24T21:13:29 < zyp> are you using a debugger? it tells you exactly where
2012-06-24T21:13:58 < philpem> I am, that's how I know it's getting stuck on line 151.
2012-06-24T21:14:08 < zyp> ah, found your problem
2012-06-24T21:14:24 < zyp> you have a typo on line 151, remove the semicolon.
2012-06-24T21:15:22 < zyp> also, why do you use a loop? when you clear the buffer once, it will remain clear until you start a new transfer and it completes
2012-06-24T21:15:42 < philpem> what I want to do is send two or three SPI bytes to the chip
2012-06-24T21:15:55 < zyp> yes?
2012-06-24T21:16:19 < philpem> for a read operation, the MRF24J04 returns the byte on MISO during the final write.
2012-06-24T21:16:31 < zyp> oh, wait, I misread your code
2012-06-24T21:16:53 < philpem> so for a 2-byte read, that's a 1-byte short address with nothing on MISO, then 0xFF on MOSI, and the response on MISO
2012-06-24T21:17:25 < zyp> your sending/receiving logic are not sane
2012-06-24T21:17:38 < philpem> that's exactly what ST's datasheet says to do
2012-06-24T21:18:14 < philpem> RM0041 page 523
2012-06-24T21:18:18 < zyp> you are sending two bytes of data at the beginning without clearing the read buffer after the first read
2012-06-24T21:18:33 < drgreenthumb> heh philpem I like that little MRF Microchip module, very cool gadget :) I have working code but it's for AVR.
2012-06-24T21:19:58 < philpem> drgreenthumb, yeah, I know :)
2012-06-24T21:20:04 < drgreenthumb> I started using it for debugging. I stick it on a breadboard with a project, and another one connected to USB on my PC and I can do printf() style dump debugging on breadboard without display :)
2012-06-24T21:20:14 < philpem> drgreenthumb, that's a really cool idea...
2012-06-24T21:20:58 < philpem> right now I'm tempted to dump the STM32 kit on ebay and switch to the PIC32. this thing is doing my head in.
2012-06-24T21:21:40 < philpem> used to think Microchip's datasheets were bad, now I'm fairly sure ST's are worse, and the Standard Peripheral Library is an absolute dog.
2012-06-24T21:21:40 < zyp> philpem, http://cgit.jvnv.net/suzumebachi/tree/drivers/l3gd20.h?h=stm32f4 <- here is some working SPI code, 0x01 is RXNE, so every loop is an RXNE wait
2012-06-24T21:22:20 < zyp> init() writes two bytes and discard the read ones
2012-06-24T21:22:51 < zyp> update() writes one byte, discards the read one, then write six dummy 0s to read six bytes
2012-06-24T21:24:06 < zyp> I'm operating directly on registers, but it's easily translated to stdperiphlib
2012-06-24T21:24:42 < philpem> that's considerably different to ST's guidelines :)
2012-06-24T21:25:03 < zyp> how so?
2012-06-24T21:25:13 < BrainDamage> btw, if you don't like stdperiphlib, there's several alternatives
2012-06-24T21:25:42 < zyp> yep

2012-06-24T21:30:05 < zyp> ah, right
2012-06-24T21:30:24 < zyp> that's probably also valid then
2012-06-24T21:30:51 < philpem> http://pastebin.com/9Tq7qhbY <<=== this one works :)
2012-06-24T21:31:26 < philpem> it's reading the TXMCR register at least

2012-06-24T21:32:22 < drgreenthumb> that took me like 2 hours :P
2012-06-24T21:32:27 < philpem> works fine when the core is much faster than the SPI, but if the SPI's faster? forget it.
2012-06-24T21:32:34 < philpem> thanks, drgreenthumb ! that'll save me a lot of time :)
2012-06-24T21:32:52 < philpem> now i just need to dig through the data sheet and find the magic values to poke into the registers :)
2012-06-24T21:33:05 < zyp> seems like it's possible to start next transfer before reading out result of the previous one, but you probably have to read it out before the next finishes then
2012-06-24T21:35:09 < zyp> hmm, RM0090 says the same
2012-06-24T21:35:12 < zyp> so yeah
2012-06-24T21:35:25 < zyp> it's correct, you just have to watch your timing
2012-06-24T21:36:01 < philpem> i'm starting to wonder if it's worth merging the STM32F4 SPL code into my codebase and switch to the F4 Discovery
2012-06-24T21:36:09 < zyp> my method may be slower since it may introduce delays between the bytes, but it's not sensitive for timing
2012-06-24T21:37:46 < philpem> somehow I think I can live with inter-byte delays :)
2012-06-24T21:38:29 < philpem> most of this code will be shuffled onto an STM32F4 soon, I'm just doing some tests on the 32VL.
2012-06-24T21:39:27 < philpem> need to figure out how to squeeze half a dozen PWM channels, an audio stream and the RF layer into an F4... thankfully the PWM is for R/C servos, so not very fast.
2012-06-24T21:39:36 < philpem> could probably use SysTick or a timer
2012-06-24T21:40:06 < Thorn> squeeze?
2012-06-24T21:41:11 < Thorn> maybe try using interrupts rather than running everything in a single loop?
2012-06-24T21:41:17 < philpem> probably will.
2012-06-24T21:41:49 < Thorn> stm32f4 is about the fastest microcontroller on earth
2012-06-24T21:42:15 < Thorn> I've yet to see a microcontroller application that would have to be 'squeezed' into it

2012-06-24T21:46:58 < philpem> DCMI could be handy too...
2012-06-24T21:47:32 < zyp> F4 got a bunch of timer channels usable for pwm
2012-06-24T21:47:58 < zyp> 6 is no problem
2012-06-24T21:48:10 < philpem> oh cool, all the timers (except the two "basic" ones) can do PWM. that's nice.
2012-06-24T21:48:23 < zyp> yep
2012-06-24T21:48:40 < zyp> and each timer has four channels, each capable of a seperate PWM value
2012-06-24T21:48:51 < philpem> DMA-driven D/A... audio out should be easy then :)
2012-06-24T21:49:08 < Thorn> it also has I2S

2012-06-24T21:55:40 < drgreenthumb> what a silly idea
2012-06-24T21:56:14 < zyp> how's that sillyer than selling them over a counter?
2012-06-24T21:56:16 < Thorn> ... and probably went to automate industrial processes with their sizable experience...
2012-06-24T21:56:37 < zyp> oh, wait
2012-06-24T21:56:47 < drgreenthumb> nobody buys an arduino over a counter :P
2012-06-24T21:56:50 < zyp> I'm thinkin vending machines to sell arduinos.
2012-06-24T21:56:59 < zyp> not vending machines based on arduinos.
2012-06-24T21:57:02 < BrainDamage> drgreenthumb: apparently radioshack sells them now
2012-06-24T21:57:10 < BrainDamage> so you can buy one over a counter
2012-06-24T21:57:23 < Thorn> no, they wanted to use arduinos to control vending machines
2012-06-24T21:57:23 < zyp> I should probably go to sleep, it's 4AM here in Japan now :p
2012-06-24T21:57:23 < drgreenthumb> BrainDamage, heh that's cool finally something cool (well sorta) at Rat Shack
2012-06-24T21:57:38 < BrainDamage> there's not even radioshack in my country
2012-06-24T21:57:39 < Laurenceb_> hehe a vending machine that sells arduinos
2012-06-24T21:57:42 < drgreenthumb> maybe the'll get Discovery boards next :P
2012-06-24T21:57:56 < Laurenceb_> you could put it next to the used underware machine in japan
2012-06-24T21:58:05 < zyp> I bought a L1 discovery board over a counter today
2012-06-24T21:58:31 < drgreenthumb> jeez where do you guys live? there's like zero electronics / hobby shops around here and it's freaking San Francisco bay :/

2012-06-24T22:37:30 < Thorn> could an stm32f4 mix 50 audio samples in tral time? http://electronics.stackexchange.com/questions/34480/chip-board-to-drive-low-latency-audio-sample-playback-and-mixing
2012-06-24T22:45:26 < Tectu> Thorn, what do you need that for?
2012-06-24T22:45:41 < Thorn> not me
2012-06-24T22:46:05 < Tectu> what would be the use for it
2012-06-24T22:49:42 < Thorn> *real  time
2012-06-24T22:49:51 < Thorn> x_x
2012-06-24T22:51:50 < BrainDamage> does the dsp get the full clock speed?
2012-06-24T22:51:58 < BrainDamage> if so then very likely
2012-06-24T22:52:08 < jpa-> Thorn: depends really more about if it can get the samples in fast enough
2012-06-24T22:52:10 < BrainDamage> since ixing is basically multiply and accumulate, the dsp would be ideal
2012-06-24T22:52:17 < BrainDamage> yeah, bus bandwith might be a problem
2012-06-24T22:52:39 < BrainDamage> you can even mix them in realtime
2012-06-24T22:53:07 < jpa-> 2 million integer multiply-accumulates per second if no problem for stm32f4
2012-06-24T22:54:22 < jpa-> in fact, the low latency from SD card is probably the trickiest part
2012-06-24T22:55:06 < BrainDamage> you could have multiple SD in parallel on diff spi busses
2012-06-24T22:55:12 < Thorn> yeah, that would depend on how randomly those samples are accessed and whether they can be preloaded
2012-06-24T22:55:15 < BrainDamage> and data being mirrored on each card
2012-06-24T22:55:15 < jpa-> though the first block of each sample should be available in about 100µs.. but if many samples start playing at the same time, the latency grows 
2012-06-24T22:55:40 < BrainDamage> also, for 2 GB you could get away with a ram slot
2012-06-24T22:56:09 < jpa-> interfacing dram is not that fun
2012-06-24T22:58:30 < jpa-> 50 samples -> 5ms designed latency should be enough to load all samples in time to start playing them..
2012-06-24T22:59:01 < jpa-> a raw memory (no filesystem, direct access to blocks) and custom scheduler to decide what blocks have the deadline first :)
2012-06-24T23:01:09 < szczys> here's a strange question for you:
2012-06-24T23:01:15 < Thorn> he'll need 25Mbytes of RAM for his 50 samples anyway
2012-06-24T23:01:40 < Thorn> 2Gb/4000 = 512 Kbytes per sample
2012-06-24T23:01:41 < szczys> I'm using OpenOCD to program my STM32F0-discovery board (it has the st-link version 2 programmer built in)
2012-06-24T23:01:56 < szczys> I have no problem flashing code to it, and can start running it by issuing the "reset" command
2012-06-24T23:02:15 < szczys> but if I the press the reset button the program halts and nothing will happen unless I power cycle
2012-06-24T23:02:24 < zippe> BrainDamage: The M4 doesn't have a "DSP"
2012-06-24T23:02:31 < szczys> once I have power cycled... I can press reset as much as I want and it performs just fine
2012-06-24T23:02:35 < szczys> any idea what's going on here?
2012-06-24T23:02:37 < jpa-> Thorn: they don't need to be fully in ram at once
2012-06-24T23:02:48 < zippe> BrainDamage: It just has a bunch of vector instructions based on VFPv4
2012-06-24T23:03:16 < BrainDamage> aww, I hoped for MAC unit
2012-06-24T23:03:19 < zippe> szczys: I've seen that occasionally; don't use 'reset', use 'run'
2012-06-24T23:04:16 < Thorn> jpa-: if you stream them ffrom flash you might introduce jitter, I think
2012-06-24T23:04:49 < zippe> BrainDamage: it has FMA, FMS
2012-06-24T23:05:28 < zippe> also regular MA, MS
2012-06-24T23:05:36 < szczys> zippe: now that I check, I"m actually using "reset run"
2012-06-24T23:06:04 < zippe> BrainDamage: it's just not a separate "DSP", rather it's just part of the regular ISA
2012-06-24T23:06:27 < zippe> In their bigger chips, ARM have separate pipeline resources for the VFP instructions
2012-06-24T23:06:35 < zippe> I suspect that in the M4 those are shared
2012-06-24T23:06:55 < Laurenceb_> yeah thats how i understand it
2012-06-24T23:08:44 < zippe> No detail in the TRM, of course

2012-06-24T23:26:38 < Laurenceb_> any idea how to force a single cell in a table to spread over all columns

2012-06-24T23:29:53 < Laurenceb_> wut
2012-06-24T23:30:00 < Laurenceb_> avr and stm compatible?!
2012-06-24T23:30:30 < karlp> so you just provide a method to do the spi transfer,
2012-06-24T23:30:47 < karlp> instead of building st specific, or avr specific spi code into the RF code itself

2012-06-25T04:11:22 < zippe> upgrdman: Look at the clock tree in the RCC chapter
2012-06-25T04:12:30 < zippe> upgrdman: in particular, if the APB prescaler for the APB bus the timer is on is 1, the clock is the same as the APB clock
2012-06-25T04:12:36 < zippe> upgrdman: otherwise, it is 2x the APB clock

2012-06-25T04:30:39 < zippe> szczys: No, you need to learn how C evaluates expressions.
2012-06-25T04:31:32 < zippe> szczys: You might try section 2.8 in the book I just linked above.
2012-06-25T04:31:46 < szczys> thanks, already there
2012-06-25T04:34:01 < szczys> so I do need to typecase to a float
2012-06-25T04:34:06 < szczys> just one of the operands
2012-06-25T04:34:11 < szczys> so that both are considered floats
2012-06-25T04:34:21 < zippe> Well, it depends on what you're trying to do
2012-06-25T04:34:24 < szczys> otherwise it's just doing integer math right now... got that right?
2012-06-25T04:34:28 < zippe> That's correct
2012-06-25T04:34:53 < zippe> Your're probably suffering due to a loss of precision in the division.  But, you should be careful.
2012-06-25T04:35:13 < szczys> yes... the result should be 0.666666666666666666666666666 but I was getting just 0
2012-06-25T04:35:21 < szczys> now it's working, thanks!
2012-06-25T04:35:26 < zippe> ((float)y2 - (float)y1)/((float)x2 - (float)x1)  is very different from   (float)(y2 - y1)/(x2-x1)
2012-06-25T04:35:29 < Thorn> >0.666666666666666666666666666
2012-06-25T04:35:31 < Thorn> >float
2012-06-25T04:35:41 < Thorn> >single precision float
2012-06-25T04:36:16 < szczys> zippe: I don't see why it would be different. from what you just gave me to read one (float) typecast should 'infect' the others
2012-06-25T04:36:27 < zippe> Heh.
2012-06-25T04:36:43 < zippe> The first example requires two float subtractions, followed by a division

2012-06-25T04:36:49 < szczys> "if either operand is a float, then the other one is converted to float, and that is the type of the result."
2012-06-25T04:36:55 < zippe> The second is two integer subtractions followed by a float division.
2012-06-25T04:37:31 < szczys> but I'm starting with all integers, I just need to end up with a float after the division
2012-06-25T04:37:35 < zippe> No
2012-06-25T04:37:46 < zippe> You need floats *before* the division
2012-06-25T04:38:31 < zippe> Cast operators are unary operators like + and -
2012-06-25T04:38:58 < zippe> (float)(x - y)  and ((float)x - (float)y) are different things.
2012-06-25T04:39:28 < szczys> If 'x' and 'y' are both integers to start... why won't the outcome of that be exactly the same number
2012-06-25T04:39:30 < zippe> The first one is "subtract y from x and then cast the result to float".  The second is "cast y to float, cast x to float, subtract"
2012-06-25T04:39:44 < szczys> are you say the machine time is different, or the value of the result is different?
2012-06-25T04:39:44 < zippe> You may lose precision if they are large integers
2012-06-25T04:39:58 < zippe> You may waste CPU time if your floating point operations are slow
2012-06-25T04:40:37 < zippe> A 32-bit ieee float only has a 24-bit mantissa
2012-06-25T04:41:18 < zippe> (including the sign bit)
2012-06-25T04:42:44 < szczys> ah-ha! You're talking about what the type 'float' can actually hold

2012-06-25T04:42:56 < szczys> but I know I'm working with integers which will all be less that 100
2012-06-25T04:43:09 < zippe> Ok.  I did not. 8)
2012-06-25T04:43:18 < szczys> so for my current purposes there's no difference in how I cast the floats, as long as I cast at least 1
2012-06-25T04:43:38 < szczys> but thank you for pointing out the diffence... with my frame of reference I never even had the notion to consider that caveat

2012-06-25T04:48:53 < zippe> Ah bollocks.  I didn't realise they had to close the Balfours cart.  That sucks.
2012-06-25T04:51:33 < upgrdman> stuff like TIM6->REGISTER uses preprocess directives, so there no way to evaluate those with gdb right? must look up memory address by hand?
2012-06-25T04:51:41 < upgrdman> preprocessor
2012-06-25T04:51:44 < zippe> Correct.

2012-06-25T05:16:57 < upgrdman> trying to get an LED on pin D15 to toggle once per second, but the LED never comes on. http://pastebin.com/3mMv7hXn any ideas?
2012-06-25T05:19:13 < dongs> man you really like to make the shit superfuckingcomplicated do you.
2012-06-25T05:20:53 < zyp> GPIO_MODER_MODER15_0 sounds like input mode
2012-06-25T05:21:04 < zyp> try GPIO_MODER_MODER15_1
2012-06-25T05:21:42 < upgrdman> dongs, how could it be any simpler? or was that a joke
2012-06-25T05:22:04 < dongs> upgrdman: its much simpler with stdperiphlib and you dont have to memorize retarded registers/definitions
2012-06-25T05:22:53 < upgrdman> zyp, _0 is correct, but i tried _1 and that did not fix anything
2012-06-25T05:24:22 < zyp> correct how?
2012-06-25T05:25:15 < zyp> if _0 is correct, the name doesn't make sense
2012-06-25T05:26:04 < upgrdman> as in without the timer, i can light up the LED just fine
2012-06-25T05:26:15 < upgrdman> and in other projects the GPIO stuff worked perfect
2012-06-25T05:27:32 < dongs> upgrdman: do you need ot od anything dumb with timer registers to make it autoreload
2012-06-25T05:28:11 < upgrdman> don't think so
2012-06-25T05:28:17 < upgrdman> and i know the ISR is being called
2012-06-25T05:28:42 < upgrdman> if i remove the TIM6->SR = 0; the LED is at half brightness... like 50% duty PWM
2012-06-25T05:31:33 < dongs> are you another one of those dudes that works without a scope or logic analyzer?
2012-06-25T05:32:25 < upgrdman> i have a scope
2012-06-25T05:32:49 < upgrdman> but see no need... its obvious 50%... and it makes sense if the IRQ isn't cleared
2012-06-25T05:33:07 < dongs> why would it make sense if irq isnt cleared
2012-06-25T05:33:17 < upgrdman> it just toggled super fast because the ISR keeps getting called
2012-06-25T05:33:36 < zyp> yes, that makes sense
2012-06-25T05:35:37 < dongs> why do you set SR to zero, isntead of specifically clearing TIM_IT bit?
2012-06-25T05:35:42 < dongs> not that it matters I guess...
2012-06-25T05:36:11 < dongs> see this is why i use stdperiphlib cuz i dont have to guess what the ufck its going to do when i say TIM_ClearITPendingBit
2012-06-25T05:36:34 < upgrdman> i see no TIM_IT in the register map
2012-06-25T05:37:08 < dongs> sorry. TIM_IT_Update or whatever
2012-06-25T05:37:12 < upgrdman> and im not using the STM std periph lib because im using linux, without an ide, and the examples STM provides are often more annoying than just reading rm0090
2012-06-25T05:37:13 < dongs> or i guess that's just be the 1st bit
2012-06-25T05:37:31 < upgrdman> yes, p.466 of rm0090
2012-06-25T05:38:01 < zyp> the only bit, since it's TIM6
2012-06-25T05:38:08 < upgrdman> yes
2012-06-25T05:38:09 < dongs> allrighty then.
2012-06-25T05:38:11 < dongs> shruggin.
2012-06-25T05:38:40 < upgrdman> i just don't know why i would get 50% pwm, but then nothing when i clear the irq
2012-06-25T05:39:25 < zyp> can you check the contents of CR1 for me?
2012-06-25T05:39:33 < upgrdman> sure, one min
2012-06-25T05:39:35 < zyp> is CEN really the only bit set?
2012-06-25T05:40:30 < zyp> because OPM would explain what's happening
2012-06-25T05:42:01 < upgrdman> (gdb) print /t *(unsigned long*) 0x40001000
2012-06-25T05:42:01 < upgrdman> $1 = 1
2012-06-25T05:42:03 < upgrdman> yes
2012-06-25T05:43:31 < zyp> set a breakpoint on the ISR and restart the application
2012-06-25T05:43:57 < upgrdman> do you know how to trigger a restart from within gdb?
2012-06-25T05:44:02 < zyp> run

2012-06-25T09:00:58 < cjbaird> Hello doggy!
2012-06-25T09:02:29 < cjbaird> What I'm really waiting on for is a Lanuchpad-style eval board of the 20-bit MSP430 chips..

2012-06-25T09:03:11 < cjbaird> (which isn't from Olimex)
2012-06-25T09:03:14 < pelrun> worked with that on a project last year
2012-06-25T09:03:32 < pelrun> vendor libraries are even worse than ST's
2012-06-25T09:03:56 < dongs> BUT you have ATMEL FRAMEWORK
2012-06-25T09:03:58 < pelrun> "oh, you want to use this code with a board that isn't one of our eval boards? fuck off"
2012-06-25T09:04:00 < dongs> and ATMEL STUDIO 6.0
2012-06-25T09:04:31 < pelrun> the whole POINT of an eval board is to help you get to a custom design
2012-06-25T09:04:36 < pelrun> not lock you into it
2012-06-25T09:04:53 < pelrun> big pile of stinky dog poo
2012-06-25T09:05:28 < pelrun> and atmel studio? don't make me laugh
2012-06-25T09:05:40 < dongs> what
2012-06-25T09:06:21 < pelrun> anyway, it's the framework I was complaining about
2012-06-25T09:06:42 < dongs> waht pissed me off is studio6 seems to have all the proper arm c ompilers and debugging setup
2012-06-25T09:06:47 < dongs> but you cant use it with anytthing except avrtrash
2012-06-25T09:06:56 < dongs> thats a big disappointment since vstudio shell is awesome.

2012-06-25T09:08:32 < pelrun> heh
2012-06-25T09:09:04 < pelrun> I think atmel's entire business plan is to make money off selling eval boards
2012-06-25T09:09:08 < pelrun> not the actual chips
2012-06-25T09:09:45 < pelrun> at least, that is what the framework project manager seems to have thought
2012-06-25T09:10:33 < pelrun> although I must admit when I finally beat it into submission it did work fairly well
2012-06-25T09:17:53 < Tectu> morning
2012-06-25T09:18:02 < Tectu> dongs, you use atmel stuff?
2012-06-25T09:18:15 < Tectu> the last avr studio i used was the 4.18
2012-06-25T09:18:20 < Tectu> is the new 6 good?
2012-06-25T09:29:34 < dongs> hi
2012-06-25T09:29:42 < dongs> 6 uses visual studio 2010 shell
2012-06-25T09:29:48 < dongs> 4.x was t heir own retarded IDE
2012-06-25T09:29:57 < dongs> I wish more companies would realize that writing iDE from scratch is fucking retarded
2012-06-25T09:30:01 < dongs> and either use vs shell or eclipse
2012-06-25T09:52:50 < blkcat> what
2012-06-25T09:53:31 < Tectu> i am never sure if i shall take  char *str;   or   unsigner char *str;   for passing strings to a function
2012-06-25T09:53:43 < Tectu> in general, i don't know if i am supposted to use char or unsigner char for storing C-Strings
2012-06-25T09:53:53 < Tectu> on AVR, i used to use unsigner char*
2012-06-25T09:59:16 < dongs> designer char.
2012-06-25T09:59:20 < dongs> by vogue
2012-06-25T10:01:17 < Tectu> what do you mean, dongs
2012-06-25T10:05:11 < dongs> < Tectu> on AVR, i used to use unsigner char*
2012-06-25T10:05:38 < dongs> it all depends what strings youre passing.
2012-06-25T10:05:46 < dongs> i.e. ascii shit with 7bits, then char works.
2012-06-25T10:06:03 < Tectu> what does not work?
2012-06-25T10:06:17 < pelrun> Tectu, use the c99 types
2012-06-25T10:06:24 < dongs> well, if you have some shit with high bit set it might be lame.
2012-06-25T10:06:27 < pelrun> but plain "char" for strings
2012-06-25T10:06:29 < dongs> yeahm juyst use uint8_t
2012-06-25T10:06:43 < pelrun> dongs: only for non-string 8-bit data
2012-06-25T10:06:52 < Tectu> uint_t types are c99? o0
2012-06-25T10:06:58 < Tectu> i remember using them in c89 all the time
2012-06-25T10:07:08 < pelrun> you end up having to recast for all the damn string functions otherwise
2012-06-25T10:07:20 < pelrun> if "char" is only for text, you don't care if it's native signed or not
2012-06-25T10:07:38 < pelrun> Tectu, they're only typedefs, after all. Just got ratified in c99.
2012-06-25T10:08:36 < Tectu> pelrun, i never saw something interesting in using c99, beside having to declare it everytime
2012-06-25T10:08:52 < Tectu> and things like   for(int i = 0....)   well...
2012-06-25T10:08:55 < Tectu> don't need it
2012-06-25T10:09:02 < pelrun> you shouldn't have to worry about whether uint16_t is an 'int' or 'short' or whatever on your particular platform, because it's in the compiler instead of a platform-specific header include
2012-06-25T10:09:18 < dongs> right
2012-06-25T10:09:22 < Tectu> right
2012-06-25T10:09:31 < Tectu> so use uint8_t instead of char? o0
2012-06-25T10:09:35 < Tectu> for strings
2012-06-25T10:09:42 < pelrun> no, I said just "char" for strings
2012-06-25T10:09:48 < Tectu> ah
2012-06-25T10:09:51 < Tectu> good
2012-06-25T10:09:53 < Tectu> thanks
2012-06-25T10:10:10 < pelrun> beyond that it's probably good to get out of the habit of mixing and matching the new and old types
2012-06-25T10:10:32 < pelrun> being explicit everywhere doesn't hurt
2012-06-25T10:11:22 < pelrun> especially if you're the poor bastard being asked to port code to a new platform :)
2012-06-25T10:13:53 < Tectu> did someone ever used palWriteGroup() macro from ChibiOS?
2012-06-25T10:14:23 < pelrun> not yet (i'll probably hit chibios fairly soon, now that I'm sticking with stm32)
2012-06-25T10:14:31 < pelrun> hope I don't go splat
2012-06-25T10:17:35 < Tectu> i am working on an offical LCD/Touchpad/GUI library for chibios

2012-06-25T10:20:17 < Tectu> like over USART

2012-06-25T10:33:27 < pelrun> I tend to use a laptop or my phone over bluetooth for a serial console :)
2012-06-25T10:33:51 < Tectu> pelrun, sounds awesome, is there some real project behind it?
2012-06-25T10:34:04 < pelrun> I'm just talking about in general
2012-06-25T10:34:49 < pelrun> I went a couple of years without an actual ftdi cable, just a serial-bt thingy I got cheap from sparkfun
2012-06-25T10:35:01 < pelrun> not nearly as cheap as they go for from china these days
2012-06-25T10:35:17 < Tectu> pelrun, link?

2012-06-25T10:36:22 < pelrun> there's another one somewhere on dx that has a 5v converter on a carrier board, but who cares on stm32? :)
2012-06-25T10:36:54 < pelrun> apparently the firmware is rather rudimentary(i.e. shit) on the cheap ones, some guy figured out how to reflash them
2012-06-25T10:37:06 < pelrun> http://byron76.blogspot.com.au/
2012-06-25T10:37:32 < pelrun> or you could just go to sparkfun and get one of their more expensive dongles that come with reasonable firmware off the bat

2012-06-25T10:51:45 < pelrun> some people use what they know

2012-06-25T14:59:48 < zyp> like they won't be available in the git history if needed :p

2012-06-26T06:15:57 < upgrdman> and i've seen atmel 328's in some cheap servos
2012-06-26T06:16:19 < upgrdman> do you know much about timers in the stm32?
2012-06-26T06:16:24 < dongs> yes i use htem
2012-06-26T06:16:35 < upgrdman> to get my TIM6 ISR to work properly I found that i had to check that TIM6->SR == 0 to see if an update event had occurred. shouldn't the ISR only be called when the event has occurred?
2012-06-26T06:17:50 < dongs> 'update'
2012-06-26T06:17:51 < dongs> vs
2012-06-26T06:17:53 < dongs> 'overflow'
2012-06-26T06:17:57 < dongs> update = each timer tick, no?
2012-06-26T06:18:21 < upgrdman> OHHH
2012-06-26T06:18:37 < upgrdman> ISR is called on each update, SR == 0 on each overflow?
2012-06-26T06:22:29 < dongs> i've only once wasted a timer the way you're wasting one, i used it for counting some stuff and blinking a led, and yes, update interrupt would fire each timer tick, i would increment stuff/blink leds, and clear IT_UPDATE or wahtever bit
2012-06-26T06:22:53 < upgrdman> ya, this is just to learn timers.
2012-06-26T06:23:07 < upgrdman> i just use systick for simple timekeeping
2012-06-26T06:26:28 < upgrdman> i suppose there's no way to make the IRQ fire only on overflows? seems kind of wasteful to run an ISR 1281 timers per second (or more) with those 16bit timers
2012-06-26T06:26:48 < upgrdman> times per second*
2012-06-26T06:29:31 < dongs> you can look at TIM_interrupt_sources
2012-06-26T06:29:42 < dongs> maybe something with trigger, I dont know
2012-06-26T06:29:58 < dongs> if  you want it slower, use slower prescaler?
2012-06-26T06:30:08 < dongs> agian, usually wasting an entier timer like that doesnt make sense
2012-06-26T06:30:13 < upgrdman> i know
2012-06-26T06:30:58 < upgrdman> this is just so i can figure it out. took me a few hours just to get the damn led to blink. i come from the easy world of the arduino and want to learn the basics now
2012-06-26T06:32:33 < upgrdman> as for the prescaler, i have the main clock PLL'd to 168MHz and the APBx prescaler at 4, so the timers see 84MHz... with the timer prescaler set to 2^16 thats still 1271.74 ticks per second. i could dick with the APB prescaler but would rather not
2012-06-26T06:34:55 < upgrdman> what's the most practical way to do something like blink an LED? use systick to updates a millis global variable and just poll that?
2012-06-26T07:06:02 < zippe> upgrdman: there are lots of ways to do it; depends a lot on the rest of your software architecture
2012-06-26T07:06:20 < zippe> upgrdman: There are heaps of timers; you could use one in PWM mode to blink via a GPIO for example
2012-06-26T07:06:35 < zippe> Or you can build a timer system and implement periodic callouts
2012-06-26T07:07:58 < zippe> I have one system here where systick decrements an array of counters to zero, one count per millisecond
2012-06-26T07:08:10 < zippe> Then I can just poll the counters in my main loop & reset them as necessary
2012-06-26T07:08:43 < zippe> In another one, I have a free-running timer with a compare interrupt set up so I can do deadline timing, independent of the RTOS that uses systick for its lbolt

2012-06-26T09:53:06 < dongs> "hi this library works (fast) but is "non free"" "ok we will write our own fail implementation from scratch then"
2012-06-26T09:54:49 < zyp> which lib?
2012-06-26T09:54:56 < dongs> FTDI
2012-06-26T09:55:12 < dongs> their 'closed sores' bitbang version was like 10x faster than opensores version
2012-06-26T09:55:19 < dongs> but they couldnt use it with openocd cuz shit wasnt  free enough
2012-06-26T09:55:21 < dongs> fuckin wankers.
2012-06-26T10:18:04 < zippe> Well now, that's interesting
2012-06-26T10:18:33 < zippe> After far too much farking around, the BDI3000 sees the same bollocks that I get from the stlink/gdb combo

2012-06-26T10:20:57 < zyp> it doesn't have anything to do with word alignment?

2012-06-26T10:21:51 < zyp> and this is happening with completely different debuggers?
2012-06-26T10:21:55 < zippe> Yes
2012-06-26T10:22:05 < zippe> I can forgive that mostly
2012-06-26T10:22:12 < zippe> The killer is that it happens with GDB too
2012-06-26T10:22:22 < zippe> i.e. if it's printing a string
2012-06-26T10:22:26 < zyp> i.e. a bug in the debugger port in the cpu core?
2012-06-26T10:22:37 < zippe> Honestly I'm not sure
2012-06-26T10:23:09 < zyp> could it somehow be intended behavior?

2012-06-26T10:23:40 < zippe> Seems odd that the stlink gdbserver would not handle unaligned memory reads sensibly (e.g. by doing byte accesses)

2012-06-26T10:25:22 < zippe> I haven't tried the "official" one
2012-06-26T10:25:30 < zippe> It would be interesting to see if I could run it in a VM I guess

2012-06-26T15:44:45 < karlp> well, I try on a somewhat regular basis
2012-06-26T15:44:52 < karlp> but no-one ever comes back tot heir own issues,
2012-06-26T15:44:56 < karlp> and texane never closes them either
2012-06-26T15:45:18 < karlp> so it's a bit hard to see what's noise and what's fixed, and what was never an issue and what should be worked on.
2012-06-26T15:45:21 < zyp> that has annoyed me as well
2012-06-26T15:45:48 < zyp> an unmaintained issue tracker is a useless issue tracker
2012-06-26T15:46:12 < karlp> indeed
2012-06-26T15:47:12 < zyp> doesn't github allow for several maintainers of a project? we should get texane to appoint some more since he's not very interested himself
2012-06-26T15:50:20 < karlp> probably a decent suggestion.

2012-06-26T19:53:38 < R2COM> ok so out of Samsung Galaxy S III and HTC One S, what would be better option?
2012-06-26T19:54:10 <+Steffanx> none is a option too?
2012-06-26T19:54:13 <+Steffanx> *an
2012-06-26T19:55:47 < R2COM> maybe
2012-06-26T19:56:00 < R2COM> theres also HTX One X with quad core coming out soon
2012-06-26T19:56:36 < R2COM> someone told me here that they are good only for 1 year while the OS is supported
2012-06-26T19:58:04 <+dekar> R2COM, I'd go for the nexus galaxy
2012-06-26T19:58:13 <+Steffanx> isn't that one 15 years old?
2012-06-26T19:58:22 <+dekar> nope
2012-06-26T19:58:38 <+Steffanx> At least ½ year
2012-06-26T19:58:42 <+dekar> it's the latest google phone
2012-06-26T19:58:56 <+dekar> w/e, it will get the android5 update later this year
2012-06-26T19:59:01 < R2COM> nexus galaxy camera is 5MP
2012-06-26T19:59:03 <+dekar> dunno whether other phones will get it
2012-06-26T19:59:03 < R2COM> not 8MP
2012-06-26T19:59:24 < R2COM> im thinking if i get something like that shit, i better get best shit or still use my 9 year old phone
2012-06-26T19:59:24 <+dekar> R2COM, so buy a proper camera then
2012-06-26T19:59:40 < R2COM> well no.. i was just thinking about universal thing
2012-06-26T19:59:45 < blkcat> i'd either wait for the one x or buy the galaxy nexus
2012-06-26T19:59:49 < R2COM> but at least with max specs
2012-06-26T19:59:58 < R2COM> well
2012-06-26T20:00:03 < R2COM> i think im gona wait for ONE X
2012-06-26T20:00:12 <+dekar> R2COM, those cameras usually suck anyway, they're full of noise
2012-06-26T20:00:17 < R2COM> ONE X has quad core and 8MP camera and better battery too
2012-06-26T20:00:46 <+dekar> R2COM, quad core means it _needs_ the bigger battery
2012-06-26T20:01:10 < blkcat> yeah, quad-core isn't really a must-have feature
2012-06-26T20:01:16 < blkcat> then again it *is* an android phone, hah
2012-06-26T20:01:36 < R2COM> what about some APP which was used to utilize 4 cores?
2012-06-26T20:01:43 < R2COM> or Android still wouldnt let it do that?
2012-06-26T20:01:56 <+dekar> R2COM, benchmarks probably use 4 cores
2012-06-26T20:02:05 <+dekar> angry birds will probably not
2012-06-26T20:02:40 < R2COM> well ONE X probably will cost couple hundred with contract
2012-06-26T20:02:48 < R2COM> maybe some more actually
2012-06-26T20:03:38 <+dekar> R2COM, so get it without contract?
2012-06-26T20:03:46 < R2COM> why?
2012-06-26T20:03:49 < R2COM> it costs more then
2012-06-26T20:03:52 <+dekar> cheaper?
2012-06-26T20:04:04 < R2COM> if someone uses phone with some company, it can sell phone much cheaper
2012-06-26T20:04:38 < R2COM> couple hundred is cheaper, without contract unlocked it would cost maybe 500 or something like that
2012-06-26T20:04:48 < blkcat> probably the smartest thing to do is buy the galaxy nexus unlocked from the google play store
2012-06-26T20:04:58 <+dekar> the iPhone contract is like 60€ per month in germany, I think buying an iPhone alone is much cheaper actually
2012-06-26T20:04:59 < blkcat> it's only $400, no contract, and the gsm radio is pentaband so you can use it with basically any carrier
2012-06-26T20:04:59 < R2COM> i see it now
2012-06-26T20:05:00 < R2COM> 400$
2012-06-26T20:05:12 <+Steffanx> The US and their $ :(
2012-06-26T20:05:22 <+Steffanx> It's at least 400
2012-06-26T20:05:24 <+Steffanx> euro here
2012-06-26T20:05:25 < R2COM> but why pay 400$, when you can wait for ONE X, and pay less?
2012-06-26T20:05:40 < blkcat> because then you're on a contract
2012-06-26T20:05:40 <+dekar> R2COM, so wait?
2012-06-26T20:05:50 < R2COM> whats problem with contract
2012-06-26T20:05:52 < R2COM> its ok
2012-06-26T20:05:53 < blkcat> but seriously like, if you've already made up your mind then why are we still talkinga bout this
2012-06-26T20:05:56 <+dekar> R2COM, wait another 10 or 20 years
2012-06-26T20:06:04 <+dekar> R2COM, android 20 will be much better :)
2012-06-26T20:06:05 <+Steffanx> Wait 30 years!
2012-06-26T20:06:20 <+Steffanx> Android will be out of the market in 2030 :P
2012-06-26T20:06:24 <+dekar> oh right, android 28 with chrome 73 will be really awesome
2012-06-26T20:06:26 <+Steffanx> Windows and iOS it is :P
2012-06-26T20:06:27 <+dekar> I would wait for that
2012-06-26T20:06:29 < R2COM> well because i was trying to choose between two competitors, SIII new one or ONE X, but nexus is not in that class
2012-06-26T20:06:35 < blkcat> yes it is
2012-06-26T20:06:48 < R2COM> hm ok
2012-06-26T20:06:56 < blkcat> advantages to galaxy nexus: it's an official google phone so it'll get updates forever and you can buy it unlocked inexpensively
2012-06-26T20:07:06 <+dekar> R2COM, your phone won't be able to run android 28, so you better wait some more
2012-06-26T20:07:08 < blkcat> rather than getting stuck in a shitty contract that'll make you pay like $2000 over the life of the device
2012-06-26T20:07:29 < R2COM> so you say there wont be difference between 8MP camera and 5MP camera on those phones?
2012-06-26T20:07:41 <+dekar> R2COM, I am pretty sure I explained you the update thing before, if you want updates then buy the google phones
2012-06-26T20:08:08 <+dekar> R2COM, if you want a new phone every other year, then buy a quad core phone from some other vendor
2012-06-26T20:08:25 < R2COM> dekar: oh so it was you telling me that if you get phones from those phone companies, they are good only for 1 year untill updates are out?
2012-06-26T20:08:27 <+dekar> R2COM, those cameras all suck
2012-06-26T20:08:34 < R2COM> ok
2012-06-26T20:08:36 < R2COM> now
2012-06-26T20:08:42 < karlp> I fixed mine, I punched out the little plastic "cover" it had.
2012-06-26T20:08:48 < karlp> the plastic got scratched to shit so fast,
2012-06-26T20:08:49 < R2COM> if i buy from google, wouldnt i again have to update?
2012-06-26T20:08:53 < karlp> it was like permanent instagram.
2012-06-26T20:09:03 < R2COM> i mean... whats the benefit getting nexus then?
2012-06-26T20:09:04 < karlp> knocked out the plastic, now I have much better pictures!
2012-06-26T20:09:07 < blkcat> if you're buying a phone for the camera then you are an idiot, haha
2012-06-26T20:09:08 <+dekar> karlp, you should patent the scratches!
2012-06-26T20:09:09 < blkcat> they're all terrible
2012-06-26T20:09:24 < karlp> no, I should sell the auto scratrching mechanism for 1 billion or something?
2012-06-26T20:09:54 <+dekar> R2COM, there are a few nokia phones with decent cameras, but that's about it
2012-06-26T20:10:18 < R2COM> dekar: but that nexus from google, its updates are not stopped after 1 year?
2012-06-26T20:10:23 < R2COM> or how does that work?
2012-06-26T20:10:59 < blkcat> R2COM: the nexus one was released two and a half years ago and it only recently stopped receiving updates
2012-06-26T20:11:27 < R2COM> then according to what you say, it doesnt make sense buying it now?
2012-06-26T20:11:28 <+dekar> R2COM, you'll probably get updates for 2 years
2012-06-26T20:11:29 < blkcat> the phone industry is moving so quickly that you probably can't expect more longevity than that update-wise, though i imagine the galaxy nexus will be supported a while longer
2012-06-26T20:11:32 < R2COM> oh
2012-06-26T20:11:48 < R2COM> and then if they do another one, they will probably stop doing updates for nexus?
2012-06-26T20:12:01 < blkcat> no
2012-06-26T20:12:02 < blkcat> they won't
2012-06-26T20:12:03 < blkcat> sigh
2012-06-26T20:12:04 <+dekar> R2COM, the last two nexus seem to get updates
2012-06-26T20:12:49 <+dekar> R2COM, so get a nokia n8
2012-06-26T20:13:04 <+dekar> R2COM, it has a decent camera and a real flash (not that LED stuff)
2012-06-26T20:13:50 < R2COM> it runs android too?
2012-06-26T20:14:47 < R2COM> heh 12 MP
2012-06-26T20:15:27 <+dekar> R2COM, nokia doesn't use android lol
2012-06-26T20:15:32 < R2COM> ok
2012-06-26T20:16:48 < blkcat> don't
2012-06-26T20:16:49 < blkcat> buy a phone
2012-06-26T20:16:51 < blkcat> for the camera
2012-06-26T20:16:59 < R2COM> ok
2012-06-26T20:17:01 <+dekar> lol
2012-06-26T20:18:13 < R2COM> basically what you say is, google provides updates for its nexus phones for much longer period than when you get HTC or Samsung from phone companies?
2012-06-26T20:18:18 < blkcat> yes
2012-06-26T20:18:27 < blkcat> you also don't have to put up with their crappy manufacturer skins
2012-06-26T20:18:28 < R2COM> and that you count as main important advantage?
2012-06-26T20:18:37 < blkcat> yes, and the fact that you can get it unlocked inexpensively
2012-06-26T20:18:40 < R2COM> i mean update
2012-06-26T20:18:44 < blkcat> and that it's a pentaband phone so it'll work on almost any gsm network
2012-06-26T20:19:03 < R2COM> i wonder when google makes a better phone then
2012-06-26T20:19:09 < R2COM> since this nexus seems now kinda old
2012-06-26T20:19:14 <+dekar> R2COM, it also has an OMAP4 SoC which is pretty well supported by the linux kernel
2012-06-26T20:19:35 <+dekar> R2COM, you still want a better camera?
2012-06-26T20:19:47 < R2COM> eno just better phone?
2012-06-26T20:19:50 < R2COM> no*
2012-06-26T20:20:00 <+dekar> R2COM, what's bad about the nexus galaxy?
2012-06-26T20:20:20 < R2COM> its not badass enough for 400$
2012-06-26T20:20:37 <+dekar> badass enough for doing what exactly?
2012-06-26T20:20:47 <+dekar> browsing the web?
2012-06-26T20:20:47 < blkcat> ...the galaxy nexus is like six months old
2012-06-26T20:20:54 <+dekar> watching youtube videos?
2012-06-26T20:20:58 < R2COM> oh really? 6 montsh?
2012-06-26T20:20:59 < R2COM> ok
2012-06-26T20:21:03 < blkcat> its specs are still equal or better to the other top-end phones on the market
2012-06-26T20:21:19 < blkcat> you pay $400 for the privilege of not being fucked over by a two-year contract
2012-06-26T20:21:28 < R2COM> hmm
2012-06-26T20:21:34 <+dekar> R2COM, given that we had the whole talk before, I feel like you have a serious problem making decisions
2012-06-26T20:21:35 < R2COM> oh and its samsung
2012-06-26T20:21:41 < blkcat> dekar: no kidding
2012-06-26T20:21:42 < blkcat> dekar: yikes
2012-06-26T20:22:01 < R2COM> no, i was just exploring some more facts, thats it
2012-06-26T20:22:25 <+Steffanx> that's that
2012-06-26T20:22:53 < R2COM> i see it also has Micro USB, so this phone would also have an opportunity to run custom App which would talk with this USB to other hardware right?
2012-06-26T20:23:00 <+dekar> R2COM, just buy it already, and in 2 or 3 years you buy a new one
2012-06-26T20:23:29 <+dekar> R2COM, they all can do that
2012-06-26T20:23:37 < R2COM> are there free Development Software to do such apps for this phone?
2012-06-26T20:24:14 <+dekar> R2COM, we had the talk before, I told you there is
2012-06-26T20:24:40 <+dekar> R2COM, how about we stop talking about android phones on ##stm32 or I feel the strong need to search for the banhammer
2012-06-26T20:25:02 < blkcat> yeah, this is really a conversation for ##android
2012-06-26T20:25:05 <+dekar> R2COM, you have all the information you need to make an educated decision
2012-06-26T20:25:13 < R2COM> yes.
2012-06-26T20:25:16 < R2COM> thanks.

2012-06-27T06:10:45 < upgrdman> f4 timers: ref man says "Interrupt/DMA generation on the update event: counter overflow" but my ISR is called on every increment, not just overflows/autoreloads... any ideas?
2012-06-27T06:15:20 < zippe> upgrdman: do you have the DMA output enabled?
2012-06-27T06:15:41 < zippe> IIRC you're using T6, are you sure that you're not seeing the DAC underrun interrupt?
2012-06-27T06:15:52 < upgrdman> no dma
2012-06-27T06:16:23 < upgrdman> yes tim6. i didnt turn on the DAC but i will check into that
2012-06-27T06:16:30 < zippe> Are you clearing UIF?
2012-06-27T06:16:51 < upgrdman> yes
2012-06-27T06:17:00 < upgrdman> i'll pastebin my working code
2012-06-27T06:18:37 < upgrdman> http://pastebin.com/SxgfLCSV
2012-06-27T06:18:48 < upgrdman> see the last line of that paste
2012-06-27T06:21:23 < zippe> So the doc for SR says you must not touch the other bits in it
2012-06-27T06:21:36 < zippe> so TIM6->SR &= ~1;
2012-06-27T06:21:55 < zippe> Try setting URS in CR1 as well
2012-06-27T06:22:46 < zippe> Also, if you don't set CEN in CR1, does your handler still get called?
2012-06-27T06:23:15 < zippe> One last one; in your while(1) loop, for extra elite points add     volatile __asm__("wfi");
2012-06-27T06:23:50 < dongs> lol
2012-06-27T06:23:56 < dongs> why not just use the cmsis intrinsic shit
2012-06-27T06:24:01 < dongs> incase someone tries to compile your crap wiht a real compiler
2012-06-27T06:24:07 < dongs> __wfi() or so; or maybe __WFI
2012-06-27T06:24:18 < dongs> zippe, i wonder why armcc doesnt allow inline asm
2012-06-27T06:24:21 < dongs> there must be a real good reason
2012-06-27T06:27:35 < upgrdman> zippe, the asm line gives: main.c:16:12: error: expected identifier or '(' before '__asm__'
2012-06-27T06:28:02 < dongs> do what i said.
2012-06-27T06:28:15 < dongs> __WFI();
2012-06-27T06:29:00 < zippe> dongs: I asked them once.
2012-06-27T06:29:04 < zippe> dongs: they said "what"?
2012-06-27T06:29:14 < dongs> zippe, not trolling, srs question.
2012-06-27T06:29:21 < zippe> dongs: srs answer
2012-06-27T06:29:43 < zippe> dongs: we were talking real money for a port of armcc to another platform
2012-06-27T06:30:02 < dongs> "what" in this context makes zero sense
2012-06-27T06:30:19 < zippe> dongs: the folks we were talking to had no idea what "inline assembler" meant.
2012-06-27T06:30:40 < zippe> dongs: the concept of inserting text, verbatim, into the token stream going to their assembler had apparently not occurred to them
2012-06-27T06:30:56 < dongs> it supports inline asm on ARM
2012-06-27T06:30:59 < dongs> but not on thumb.
2012-06-27T06:31:12 < dongs> im thinking its due to the fact that 99.9% of the time compiler can do a better job than whatever the user thinks.
2012-06-27T06:31:36 < zippe> dongs: Sure; the issue is when there's no way to express what you want in the source language
2012-06-27T06:31:43 < zippe> case in point : WFI
2012-06-27T06:31:50 < upgrdman> SHIT! i tried
2012-06-27T06:31:53 < upgrdman> __WFI
2012-06-27T06:31:56 < zippe> or any of the CP register accesses
2012-06-27T06:32:08 < zippe> upgrdman: don't worry about it
2012-06-27T06:32:19 < upgrdman> now the red led by the headphone port is lit and stlink wont recognize my board
2012-06-27T06:32:20 < zippe> Go research it; I might have the syntax wrong. 8)
2012-06-27T06:32:38 < dongs> uhoh
2012-06-27T06:32:55 < zippe> upgrdman: which debugger are you using?
2012-06-27T06:33:14 < upgrdman> gdb but im not in the debugger right now
2012-06-27T06:33:21 < zippe> Ok.

2012-06-27T06:35:00 < zippe> Unless ST are dirtbags they won't have tied reset to TRST

2012-06-27T06:36:25 < upgrdman> yes
2012-06-27T06:36:33 < zippe> Ok, so let go of the reset button and try again
2012-06-27T06:36:44 < zippe> The flasher needs the CPU to run, so you can't keep it in reset.
2012-06-27T06:36:54 < zippe> But basic debug access should work even with the CPU reset
2012-06-27T06:37:14 < dongs> can also reflash via uart bootlaoder for usre
2012-06-27T06:37:16 < dongs> sure
2012-06-27T06:37:20 < dongs> or maybe USB's DFU shit if its f4
2012-06-27T06:37:33 < dongs> or at least erase flash
2012-06-27T06:38:09 < zippe> Yeah, it may be as simple as the stlink tool doesn't understand how to get the core out of WFI

2012-06-27T06:39:33 < zippe> hit 'c' to make it continue, then hit the reset button
2012-06-27T06:39:38 < zippe> You should stop at the reset vector

2012-06-27T06:46:20 < zippe> Which "this"?
2012-06-27T06:46:37 < zippe> If you mean the "I don't know what chip this is", it's usually just the stlink chain failing somewhere
2012-06-27T06:47:17 < zippe> It screws up the JTAG interface and doesn't reset it properly when it tries to recover
2012-06-27T06:49:22 < upgrdman> yes, ok
2012-06-27T06:49:39 < upgrdman> hum
2012-06-27T06:50:11 < upgrdman> this problem crops back up if i put __WFI(); in my infinite loop... could that be what tripped up my MCU?

2012-06-27T18:04:57 < cjbaird> No, it's site that was set up to be a commercial flog blog by someone no directly involved with TI. The forums are "year 2002 thinking" about trying to tie people to the site, with active discoragement from users using other places (github et.al). Its attitude is way too much like geocaching.com for my liking.

2012-06-27T18:05:45 < cjbaird> That they've succeeded into 'taking over' the open source MSP430 scene is annoying.

2012-06-27T18:07:50 < karlp> talks more to msp430 users than anything else
2012-06-27T18:07:57 < karlp> but, same as avrfreaks right?
2012-06-27T18:07:59 < cjbaird> That, and using phpBB for a /technical/ forum is fucking stupid.
2012-06-27T18:08:23 < karlp> why does it matter what forum software they use?
2012-06-27T18:08:31 < cjbaird> avrfreaks was probably the inspiration, but I've never used the sites.
2012-06-27T18:09:21 < cjbaird> phpBB/vBulletin makes for low signal/noise 'chatty' forums. Find me one which doesn't have posting whores...

2012-06-27T18:10:29 < karlp> so what, changing forum software instantly makes the users better?
2012-06-27T18:11:00 < cjbaird> It's the whole style/interface of forum.

2012-06-27T18:11:46 < gnomad> Personally, I hate forums. mailing lists works much better.
2012-06-27T18:12:14 < gnomad> the people who don't like mailing lists are the people too stupid to figure out how to filter their email.
2012-06-27T18:12:56 < gnomad> that's a big part of the reason why mailing lists are so much better -- they are great idiot filters.
2012-06-27T18:13:15 < cjbaird> There was a great talk several years ago at a Linux.conf about /why/ Linux's kernel devs have stuck with the mailing-list forum (+irc) model in the face of phpBB and friends.. The word "sucks" was used a lot, but wasn't the only reason..

2012-06-27T18:16:44 < karlp> mailing lists are fine as long they have people on them that live in the world where attachments are ok.

2012-06-27T21:38:14 < Rickta59> so you don't mess up the directions of the bits or the configuration
2012-06-27T21:38:49 < szczys> like a safety if you have fragile hardware connected?
2012-06-27T21:39:02 < szczys> so you init the I/O then lock it before starting the program running?
2012-06-27T21:39:22 < jpa-> yeah
2012-06-27T21:39:26 < Rickta59> yeah i think that is how it is supposed to work
2012-06-27T21:39:48 < szczys> okay, didn't know if there was some kind of like consumer product IP security feature that it provided or whatever
2012-06-27T21:40:19 < Rickta59> I think once you lock it you can't change it until you reset
2012-06-27T21:41:21 < szczys> yes, I believe you're right
2012-06-27T21:42:33 < jpa-> some other peripherals have similar safety features

2012-06-27T23:39:12 < Laurenceb_> if its just doped tracks that are resistive, then it should run fine right?
2012-06-27T23:39:28 < BrainDamage> in that case it might work
2012-06-27T23:39:34 < Laurenceb_> it looks like a neat way to fix the issue
2012-06-27T23:39:49 < BrainDamage> the only issue I have in mind is the metal-semiconductor junctions
2012-06-27T23:39:53 < BrainDamage> at the bonding pads
2012-06-27T23:40:17 < Laurenceb_> but there is one at both pins?
2012-06-27T23:40:18 < BrainDamage> I hope they added ion implantation to make sure it's ohmic and not another diodes
2012-06-27T23:40:58 < BrainDamage> well, depends if they contact doped Si or polysilicon
2012-06-27T23:41:00 < Laurenceb_> multimeter seems to think its ohmic in both directions
2012-06-27T23:41:21 < Laurenceb_> which is ohmic?
2012-06-27T23:41:30 < BrainDamage> poly is ohmic
2012-06-27T23:41:50 < BrainDamage> I'm going to trust your multimeter and tell you to try it
2012-06-27T23:41:53 < BrainDamage> you should be ok
2012-06-27T23:42:07 < Laurenceb_> ok
2012-06-27T23:42:25 < Laurenceb_> the honeywell datasheet says they work in either direction
2012-06-27T23:42:39 < Laurenceb_> and they seem to be similar construction
2012-06-27T23:43:12 < Laurenceb_> ill have a play around tomorrow with my decent hot air station
2012-06-27T23:43:34 < Laurenceb_> need to lift the sensors off
2012-06-27T23:46:04 < Laurenceb_> will leaving the substrate floating give any issues?
2012-06-27T23:46:13 < Laurenceb_> datasheet seems to show it floating
2012-06-27T23:47:48 < Laurenceb_> is it only there to help with EMI here?
2012-06-27T23:47:59 < Laurenceb_> -the substrate pin
2012-06-27T23:50:24 < BrainDamage> mmm, thing is, if you leave it floating, the pn junction will make a more or less global short if by chance it goes to a potential higher than a part of your circuit
2012-06-27T23:50:45 < BrainDamage> as in, any area where the pn-junction is actively polarized, leaks current and is sorta shorted
2012-06-27T23:51:04 < BrainDamage> and you got a potential gradient all the way from vcc to gnd on your chip
2012-06-27T23:51:41 < BrainDamage> ( diodes leak current in forward even if you're less than their active forward drop )
2012-06-27T23:51:44 < Laurenceb_> surely the current can only leak in one direction?
2012-06-27T23:51:49 < Laurenceb_> ah
2012-06-27T23:52:11 < BrainDamage> just not a lot of current
2012-06-27T23:52:26 < BrainDamage> I guess to get full precision you should bias it
2012-06-27T23:52:36 < Laurenceb_> hmm i see
2012-06-27T23:52:49 < Laurenceb_> yeah smallleakage may screw up a sensitive sensor
2012-06-27T23:53:06 < Laurenceb_> needs a bit of wire still then - to 3v3
2012-06-27T23:53:30 < BrainDamage> btw, even reverse polarized diodes do leak current
2012-06-27T23:53:34 < BrainDamage> but it's generally tiny
2012-06-27T23:53:53 < BrainDamage> ( generation-recombination current )
2012-06-27T23:53:54 < Laurenceb_> im using a variable LDO with 1.2v reference and a 12K resistor to set the current
2012-06-27T23:53:56 < Laurenceb_> yeah
2012-06-27T23:53:59 < BrainDamage> and that'd be current towards bulk
2012-06-27T23:55:06 < Laurenceb_> odd the Nsub is just floating in the datasheet
2012-06-27T23:55:31 < Laurenceb_> i may dismantle my omron blood pressure sensor and take a look
2012-06-27T23:57:10 < Laurenceb_> as they use the same sensors

2012-06-28T12:42:00 <+dekar> Thorn, I'd guess you can only fan out so many pins of you do that, but besides that I don't see the problem
2012-06-28T12:43:27 < Thorn> well, power network impedance, distributed power-to-gnd capacitance, shielding signal layers from each other, referencing signals to a ground plane, etc.
2012-06-28T12:44:33 < Thorn> however apparently even sdram can work @ 133 MHz in 2 layer designs

2012-06-28T22:01:19 < Tectu> Thorn, yeah, a few days ago
2012-06-28T22:01:22 < Tectu> could be pretty nice
2012-06-28T22:03:36 < BrainDamage> I'd have preferred an l0

2012-06-28T22:08:54 < Thorn> that's not about protection from the Chinese, is it?
2012-06-28T22:11:03 < karlp> l0 is in the literature, so I guess it's just not here yet...
2012-06-28T22:13:05 < Thorn> what ls l0?
2012-06-28T22:13:26 < BrainDamage> L1 with cortex-m0
2012-06-28T22:13:32 < BrainDamage> which means even lower power
2012-06-28T22:13:39 < BrainDamage> and hopefully cheaper
2012-06-28T22:13:46 < Thorn> main mavigation menu: stm32 f1, f2, f0, f4, l1 and f3, in that order. stm is being stm.

2012-06-28T22:44:29 < Laurenceb_> wut
2012-06-28T22:44:34 < Laurenceb_> surely overkill?
2012-06-28T22:44:54 < Laurenceb_> the freescale M4s have a 16bit adc tho
2012-06-28T22:45:12 < Thorn> stm32f3 does too
2012-06-28T22:45:35 < Laurenceb_> yeah but its unobtainable
2012-06-28T22:45:59 < Laurenceb_> having said that so are the 16bit adc freescale ics  :P
2012-06-28T22:46:08 < Thorn> but ddr3 can do up to 1.6Gx16 bits / second, right? what does it have to do with a microcontroller?

2012-06-28T22:49:34 < karlp> freescale KL0 looks cool too.
2012-06-28T22:50:29 <+Steffanx> What for karlp ?
2012-06-28T22:51:12 <+Steffanx> I'm a little lost in the low power world, they all claim to have the uc with the lowest power usage
2012-06-28T22:51:50 < Laurenceb_> hehe i know
2012-06-28T22:51:59 < Laurenceb_> stm32 isnt brilliant aiui
2012-06-28T22:52:09 < Laurenceb_> L1 is pretty close to the best tho
2012-06-28T22:52:18 < Laurenceb_> aiui msp430 still wins, just
2012-06-28T22:52:47 < Thorn> energy micro?
2012-06-28T22:52:50 < BrainDamage> msp430 tough is 16 bit
2012-06-28T22:52:54 < BrainDamage> and magnitudes slower
2012-06-28T22:53:07 < Thorn> how about some EFM32
2012-06-28T22:53:35 < BrainDamage> I guess one should look at MIPS/w, or some similar parameter
2012-06-28T22:54:10 <+Steffanx> BrainDamage: /nick one
2012-06-28T22:54:14 < Laurenceb_> yeah
2012-06-28T22:54:47 < BrainDamage> Steffanx: what does that mean?
2012-06-28T22:55:02 <+Steffanx> "I guess one should" <= 'one' :P
2012-06-28T22:55:10 <+Steffanx> You should change your nick in 'one'
2012-06-28T22:55:40 < BrainDamage> ok, then /nick nottoday
2012-06-28T22:55:54 < BrainDamage> I had 3h sleep, an exam, and a denstist appointment
2012-06-28T22:56:32 < BrainDamage> oh, and I've been forced to fast until dinner due to awful scheduling
2012-06-28T22:57:09 <+Steffanx> Forced to 'fast'?  What's that?
2012-06-28T22:57:20 <+Steffanx> A 5 minute appointment with your dentist?
2012-06-28T22:57:25 <+Steffanx> *minutes
2012-06-28T22:57:35 <+Steffanx> Oops nvm :P
2012-06-28T22:57:41 <+Steffanx> my english fails terrible
2012-06-28T22:57:49 <+Steffanx> y
2012-06-28T22:58:07 < karlp> freescale KL0 is in a 32pin LQFP, 0.8mm pitch, so easier to solder.
2012-06-28T22:58:15 < Laurenceb_> i didnt understand either
2012-06-28T22:58:15 < karlp> no usb for apps where you don't need that
2012-06-28T22:58:20 < karlp> so should be cheaper
2012-06-28T22:58:22 < Laurenceb_> what core?
2012-06-28T22:58:25 < karlp> m0+
2012-06-28T22:58:31 < Laurenceb_> boo
2012-06-28T22:58:45 <+Steffanx> fast as in 'don't eat' Laurenceb_ :P
2012-06-28T22:59:05 < Laurenceb_> i know now
2012-06-28T22:59:08 < karlp> smallest lqfp in the kl1 though is 64 :(
2012-06-28T22:59:12 <+Steffanx> i like that 4x4 mm package karlp
2012-06-28T22:59:35 < karlp> but, no discovery board :)
2012-06-28T22:59:36 < Laurenceb_> yeah, annoying that smallest stm32f4 is 64pin
2012-06-28T23:00:03 < Laurenceb_> the 48pin f1 is perfect
2012-06-28T23:00:09 <+Steffanx> 36 pins
2012-06-28T23:00:17 < karlp> hmm, freescale k10 is in <64pin isn' tit?
2012-06-28T23:03:24 <+Steffanx> 32 karlp
2012-06-28T23:03:35 <+Steffanx> So, yes
2012-06-28T23:03:56 < Thorn> wait, those freescale chips with ddr3 are cortex-a5 + cortex-m4?
2012-06-28T23:04:02 < Thorn> that would make sense
2012-06-28T23:04:12 <+Steffanx> Also the m4 only
2012-06-28T23:05:21 < Thorn> Kinetis X?
2012-06-28T23:05:22 < Thorn> wtf.
2012-06-28T23:05:29 <+Steffanx> Yes
2012-06-28T23:05:34 <+Steffanx> It has support for DDR3
2012-06-28T23:05:59 < Thorn> what typical microcontroller user would be able to implement ddr3?
2012-06-28T23:06:46 <+Steffanx> Someone with skills
2012-06-28T23:07:06 < Thorn> and $$$$$$$$$$ for HyperLynx, scopes etc.
2012-06-28T23:09:16 < Laurenceb_> we used ddr3 at my old job
2012-06-28T23:09:24 < Laurenceb_> with M3 softcore on a vertex5
2012-06-28T23:11:08 < Thorn> that's what I'm talking about, fpga designers normally know how to use it and have the tools, but not those who use microcontrollers exclusively
2012-06-28T23:12:16 < Laurenceb_> the M3 softcore was insane
2012-06-28T23:12:22 < Laurenceb_> luckly i didnt deal with it
2012-06-28T23:12:41 < Laurenceb_> one guy was on the phone pretty much all day to arm trying to make it behave
2012-06-28T23:14:02 < karlp> I dind't know they did an m3 softcore
2012-06-28T23:14:16 < karlp> teh m1 is the m0 tweaked for softcores right?

2012-06-29T05:12:21 < zippe> Thorn: Reason to use mDDR3 is lower power, higher density than SRAM
2012-06-29T05:13:07 < zippe> Thorn: Also lower cost, and depending on the memory controller possibly easier configuration due to auto-tuning rather than hardcoded magic numbers.
2012-06-29T05:13:55 < zippe> By "typical microcontroller user", I think someone is missing something.  In particular, confusing "typical microcontroller hobbyist on IRC or forums" for "typical volume microcontroller purchaser"

2012-06-29T06:25:14 < upgrdman> externally clocked timers: what are TIx? I know they're inputs but how do i find out what pin they are or can be
2012-06-29T06:31:08 < dongs> talking about section 5.2.11 in reference manual?
2012-06-29T06:31:40 < dongs> I thought only a couple timers could be clocked externally.
2012-06-29T06:32:06 < dongs> but if talking about general shit (like input capture)
2012-06-29T06:32:13 < dongs> then I'd guess TIx means channel 1,2 3 etc
2012-06-29T06:32:19 < dongs> so it wouldbe shit like TIM1_CHx
2012-06-29T06:32:23 < dongs> in pinout.
2012-06-29T06:38:48 < upgrdman> i guess input capture
2012-06-29T06:39:25 < upgrdman> im using the f4disco board, and the user manual for it has a table of pin numbers and alternate functions
2012-06-29T06:40:12 < upgrdman> but there are at least three pins that can be "TIM2_CH1_ETR"
2012-06-29T06:42:58 < upgrdman> and some of them just say "TIM13_CH1" ... no _ETR ... whats the difference?
2012-06-29T06:43:26 < dongs> possible to use as external trigger stuff I guess.
2012-06-29T06:43:32 < dongs> for advanced timers.
2012-06-29T06:43:40 < dongs> but otherwise just regular capturecompare.

2012-06-29T07:07:28 < dongs> yes of course
2012-06-29T07:07:42 < upgrdman> ok, is current draw the only reason?
2012-06-29T07:07:43 < dongs> running peripheral consumes power
2012-06-29T07:07:50 < dongs> also I'd imagine it could be adding more noise

2012-06-29T17:33:19 < dongs> I'm working on the OSD right now, but having a little difficulty with programming the dspic. Lifted the PGD pad on the ICSP connector. Looks like some fine soldering is necessary if I can't fix the pad. But all shorts are gone, seems from time to time I get them but a bit of isopropyl and rework and they go away, not sure why they are only just appearing though?!

2012-06-29T17:33:56 < dongs> from jun 7
2012-06-29T17:34:08 < Laurenceb> lol
2012-06-29T17:34:46 < dongs> everytime you think you're failing, think about tom66 and you;ll feel better.

2012-06-29T17:34:58 < Laurenceb> the hellll
2012-06-29T17:35:04 < Laurenceb> why do i have code there
2012-06-29T17:35:06 < dongs> ror
2012-06-29T17:35:12 < dongs> thats like a japanese lol.
2012-06-29T17:35:37 < Laurenceb> something is badly wrong with my code
2012-06-29T17:35:48 < dongs> try re-indenting it
2012-06-29T17:35:49 < zyp> or your debugging

2012-06-29T17:37:06 < Laurenceb> looks ok?
2012-06-29T17:37:20 < dongs> thats a lot of stolen IP
2012-06-29T17:37:27 < dongs> how much of that is your actual code
2012-06-29T17:37:58 < Laurenceb> :P
2012-06-29T17:38:18 < Laurenceb> hmm something is badly screwed
2012-06-29T17:38:42 < Laurenceb> theres a bunch of random crap starting at 0x00000000

2012-06-29T17:38:59 < Laurenceb> that sends the dissasembler into a loop
2012-06-29T17:39:07 < dongs> hello ram, meet stack.
2012-06-29T17:39:45 < zyp> Laurenceb, huh?
2012-06-29T17:39:47 < Laurenceb> it could be the tnt code im compiling
2012-06-29T17:39:58 <+Steffanx> Who knows
2012-06-29T17:40:02 < Laurenceb> zyp: arm-none-objdump goes into a loop
2012-06-29T17:40:06 < zyp> 0x0 is aliased to 0x8000000 when booting from flash.
2012-06-29T17:40:09 < Laurenceb> sure
2012-06-29T17:40:17 < Laurenceb> but this is from the elf
2012-06-29T17:40:31 < zyp> uh
2012-06-29T17:40:40 < Laurenceb> it starts at 0x08000000 then goes through ok looking code
2012-06-29T17:40:42 < zyp> then you're looking at irrelevant sections or something
2012-06-29T17:40:49 < Laurenceb> ill grab the elf

2012-06-29T17:42:29 < Laurenceb> wait wtf
2012-06-29T17:42:31 < Laurenceb> its 8MB
2012-06-29T17:42:46 < zyp> of course, why not?
2012-06-29T17:43:23 < Laurenceb> oh yeah that seems to be normal
2012-06-29T17:43:25 < zyp> if you got 100k of actual code, 8M of metadata is not unrealistic
2012-06-29T17:44:12 < zyp> can't see anything wrong, seems sane to me
2012-06-29T17:44:36 < Laurenceb> can you dissassemble?
2012-06-29T17:44:41 < zyp> sure
2012-06-29T17:44:51 < Laurenceb> hmm - how?
2012-06-29T17:45:12 < zyp> arm-none-eabi-objdump -d main.elf of course

2012-06-29T17:48:43 < Laurenceb> hardfaults there
2012-06-29T17:48:55 < Laurenceb> but its just a few instructions after it inits the LSE
2012-06-29T17:49:21 < Laurenceb> everything continuity tests fine
2012-06-29T17:49:42 < Laurenceb> on the pcb, the only thing i changed is i removed the 100nF cap on VBackup
2012-06-29T17:50:34 < zyp> no, it can't hardfault there
2012-06-29T17:51:01 < zyp> a compare between a register and a literal can't hardfault.
2012-06-29T17:51:32 < Laurenceb> hmm i think my linker script is causing confusion
2012-06-29T17:51:39 < Laurenceb> its some sort of fault
2012-06-29T17:51:58 < zyp> then find out what's causing it
2012-06-29T17:52:12 < Laurenceb> is there a status register i need to read?
2012-06-29T17:52:18 < zyp> first confirm that it's a hardfault
2012-06-29T17:52:29 < Laurenceb> how?
2012-06-29T17:52:35 < zyp> check contents of psr (xpsr, cpsr, whatever) with info register
2012-06-29T17:52:45 < zyp> lower 9 bits or so are handler number, hardfault is 3
2012-06-29T17:52:53 < zyp> i.e. active ISR
2012-06-29T17:52:55 < Laurenceb> so whats the gdb command?
2012-06-29T17:52:59 <+Steffanx> info reg
2012-06-29T17:53:00 < zyp> info registers
2012-06-29T17:53:03 < Laurenceb> ok
2012-06-29T17:53:06 < Laurenceb> sec
2012-06-29T17:53:10 <+Steffanx> 1
2012-06-29T17:53:11 <+Steffanx> 0
2012-06-29T17:53:50 < zyp> if it's a hardfault, it's likely promoted from some other fault that's disabled, read SCB.CFSR to find the origin of the fault

2012-06-29T17:55:05 < Laurenceb> so 15?
2012-06-29T17:55:39 < zyp> ah, yes
2012-06-29T17:55:49 < zyp> isn't that systick or something?
2012-06-29T17:56:16 < zyp> yup, 15 is systick
2012-06-29T17:56:31 < zyp> so, you're in your systick ISR
2012-06-29T17:56:52 < Laurenceb> wuutttt
2012-06-29T17:57:12 < Laurenceb> oh i know
2012-06-29T17:57:21 < Laurenceb> wrong ISR name?
2012-06-29T17:57:39 < Laurenceb> so i sends me to the default handler?
2012-06-29T17:58:35 < zyp> how would I know?
2012-06-29T17:58:43 < zyp> oh, wait, I have the elf
2012-06-29T17:59:06 < zyp> yep, systick vector points to default handler
2012-06-29T17:59:50 < zyp> hmm, you don't have any fault handlers at all
2012-06-29T18:00:38 < Laurenceb> i fail
2012-06-29T18:00:43 < Laurenceb> thanks
2012-06-29T18:00:46 < zyp> all vectors 2-15 point to __STM32DefaultExceptionHandler
2012-06-29T18:04:27 < Laurenceb> how can i fix that?
2012-06-29T18:05:15 < Laurenceb> add template irq handlers with a while loop inside?
2012-06-29T18:07:28 < zyp> huh?
2012-06-29T18:07:52 < zyp> the default handler is ok for stuff you don't need.

2012-06-29T18:14:18 < zyp> other fault handlers than hardfault also have to be implemented, otherwise they will just promote to hardfault

2012-06-29T18:46:51 < zyp> or just bad technique
2012-06-29T18:47:13 < zyp> you're supposed to melt just the solder, not the component itself
2012-06-29T18:51:15 < Thorn> even with my stellar soldering skills I never overheated a smd led
2012-06-29T18:51:45 < Thorn> I don't think it's so easy to do
2012-06-29T18:52:18 < zyp> no it's not
2012-06-29T18:52:21 < dongs> o amn
2012-06-29T18:52:22 < dongs> man
2012-06-29T18:52:27 < dongs> apaprently thisserial baller mouse shit
2012-06-29T18:52:29 < dongs> isnt actually fixable
2012-06-29T18:52:36 < dongs> it triggers on devices @ 9600baud
2012-06-29T18:52:39 < dongs> like 90% of hte time
2012-06-29T18:52:42 < dongs> Fucking shit
2012-06-29T18:52:47 < zyp> cute
2012-06-29T18:53:11 < zyp> I guess you should call the developer of the OS you paid for, and demand that they fix it
2012-06-29T18:53:14 < Thorn> also I always set my iron to 280C
2012-06-29T18:53:45 < zyp> for what kind of solder?
2012-06-29T18:53:52 < zyp> 280 sounds cool
2012-06-29T18:54:06 < dongs> > I've found in the past that if a device presents itself to Windows as a COM port and then starts transmitting automatically as soon as it is connected to the system that it gets seen as a mouse. This is regardless of the data it sends
2012-06-29T18:54:10 < Thorn> leaded of course
2012-06-29T18:54:10 < dongs> lol.
2012-06-29T18:54:25 < zyp> I'm using 360 for leaded
2012-06-29T18:55:05 < Thorn> that's a lot imo
2012-06-29T18:56:01 < zyp> you want enough heat to melt the solder quickly, so you can get the job done in a low amount of time, thus reducing overall component heatup
2012-06-29T18:56:05 < Thorn> maybe my station shows inaccurate temperatures
2012-06-29T18:56:16 < Laurenceb> wow
2012-06-29T18:56:31 < Laurenceb> some kingbright high brightness 0603 leds are very fragile
2012-06-29T18:56:43 < Thorn> my station melts solder pretty much instantly at that temperature
2012-06-29T18:56:44 < Laurenceb> truns out the heat breaks the gold bondwires
2012-06-29T18:56:56 < Laurenceb> i had to solder with 250C iron
2012-06-29T18:57:03 < Laurenceb> and use only a few seconds of heatr
2012-06-29T18:57:03 < zyp> I don't really remember how I got to 360, but that's been a rule of thumb I've used for years
2012-06-29T18:57:37 < zyp> Thorn, yes, but solder doesn't adhere to cold surfaces
2012-06-29T18:58:10 < zyp> have you ever tried to solder something thick with a weak iron?
2012-06-29T18:58:45 < cjbaird> 250 is what I use, albeit for mostly through-hole work, and I have things fluxed and tinned beforehand. Occassionally 280-300 if there's a reason for some heat..
2012-06-29T18:59:54 < Laurenceb> owww
2012-06-29T19:00:03 < Laurenceb> these things are too bright
2012-06-29T19:00:26 < Laurenceb> blinding with just 4ma
2012-06-29T19:00:46 < zyp> depends on the use
2012-06-29T19:00:46 < cjbaird> Enjoy your remaining eye..
2012-06-29T19:01:00 < zyp> I like actually being able to see them when outdoors

2012-06-29T19:02:32 < Laurenceb> lol
2012-06-29T19:02:50 < Laurenceb> its poractically burning out the camera
2012-06-29T19:03:10 < zyp> ah, right, I'm using the same ones as dongs

2012-06-29T19:04:26 < dongs> irc looks like wokr
2012-06-29T19:04:48 < zyp> dongs, the simplest trick is to not use flash

2012-06-29T19:05:11 < dongs> i've followed some pro-photofag advice
2012-06-29T19:05:19 < dongs> but even he said its not really possible with leds
2012-06-29T19:05:45 < zyp> well, how do you wnat to show brightness?
2012-06-29T19:06:01 < zyp> a picture can't be brighter than the display it's viewed on
2012-06-29T19:06:08 < dongs> heh, right
2012-06-29T19:06:41 < zyp> your pic is not that bad actually
2012-06-29T19:07:03 < zyp> it shows that they are so bright that the camera failed to get the color of the middle one
2012-06-29T19:07:19 < Thorn> you need two exposures when shooting leds, one with them on and no other light, another with leds off and the rest of the picture exposed correctly
2012-06-29T19:07:46 < Thorn> that's how they did it with large format cameras 50+ years ago
2012-06-29T19:07:57 < zyp> Thorn, or just balance those two

2012-06-29T19:09:16 < Thorn> in the age of photoshop you can do whatever you want with them
2012-06-29T19:09:19 < zyp> it's easy when you use flash, because then flash will expose the rest of the image, while shutter speed will control the exposure of the leds only
2012-06-29T19:09:38 < zyp> you don't have to resort to photoshop tricks if you know how to use a camera

2012-06-29T19:11:06 < dongs> haha
2012-06-29T19:11:29 < zyp> Thorn, jtag/swd
2012-06-29T19:11:39 < Thorn> what's the p/n?
2012-06-29T19:11:43 < zyp> it's the default cortex debug connector pinout
2012-06-29T19:12:05 < zyp> don't remember, it's from digikey
2012-06-29T19:13:09 < zyp> http://bin.jvnv.net/f/cT7wW.JPG http://bin.jvnv.net/f/nMnwo.JPG <- oh, and both those are taken with lcd backlight on, the difference is shutter speed
2012-06-29T19:13:16 < Thorn> but it's not 0.1" pitch, is it
2012-06-29T19:13:41 < zyp> 0.05"

2012-06-29T20:15:11 < Thorn> nice
2012-06-29T20:15:41 < dongs> github more like ghettohub
2012-06-29T20:16:10 <+Steffanx> Special version for donga dong dongs
2012-06-29T20:16:12 < Thorn> the idea seems pretty obvious post factum
2012-06-29T20:16:29 < dongs> what are tehy doing?
2012-06-29T20:16:35 < dongs> loading blackmagic firmware on stlink?
2012-06-29T20:16:47 < dongs>  but it only works on lunix w/openocd right?
2012-06-29T20:16:51 <+Steffanx> No
2012-06-29T20:16:52 < dongs> so that kinda makes stlink a bit useless.
2012-06-29T20:17:09 <+Steffanx> the bmp is it's own gdb server ..
2012-06-29T20:17:15 < Thorn> dongs: it has builtin openocd
2012-06-29T20:17:18 <+Steffanx> over a virtual serial connection
2012-06-29T20:17:21 < Thorn> so to say
2012-06-29T20:17:46 < dongs> mhmm.
2012-06-29T20:17:59 <+Steffanx> And it works on windows, linux and os x thanks to that

2012-06-29T20:20:10 < Thorn> real bmp is $75 x_x (and I've no idea about shipping from NZ too)
2012-06-29T20:20:19 < Thorn> I also want several

2012-06-29T20:34:35 <+Steffanx> You can also buy it to support gsmcmullin, Thorn :P
2012-06-29T20:34:56 < Thorn> yea that would be a good thing to do, but.
2012-06-29T20:35:03 <+Steffanx> money?

2012-06-30T12:06:29 < dongs> http://i.imgur.com/doAG0.png this does NOT work the way one would expect
2012-06-30T12:08:30 < dongs> luckily single removed component and a jumpwire saves the day.
2012-06-30T12:08:34 < dongs> Laurenceb style
2012-06-30T12:08:35 <+Steffanx> Uhm, what should one expect?
2012-06-30T12:09:03 < dongs> Steffanx: B side plugged in, only B circuit is powered. A side plugged in, A + B circuit is powered.
2012-06-30T12:10:34 < jpa-> so why doesn't it work?
2012-06-30T12:11:24 < dongs> fucking analog shit
2012-06-30T12:11:26 < dongs> is why

2012-06-30T12:12:27 <+Steffanx> +is somewhere
2012-06-30T12:12:33 < dongs> so i dumped the nmos, and wrote some code for the MCU thats powered by A side
2012-06-30T12:12:40 < dongs> to pull ABGATE down on powr up.

2012-06-30T12:48:13 < jpa-> because it doesn't spin around the motor axis, but instead around some random axis.. and i don't understand the physics involved

2012-06-30T13:59:03 < Thorn> why a series LC circuit?
2012-06-30T13:59:33 < dongs> i dont know, you tell me. i literally grabbed this out of some other device that was massproduction-tested.
2012-06-30T14:00:07 < Thorn> also, where is shield and where is ground? because if 6 and 7 is ground it makes even less sense
2012-06-30T14:00:15 < dongs> 6/7 is shield

2012-06-30T18:10:47 < zyp> charger was apple, already picked up a replacement for that
2012-06-30T18:11:08 < zyp> and I had an old OS installation on the other drive in the laptop, which booted up fine once I removed the ssd
2012-06-30T18:12:33 < zyp> unsure about the actual status of the ssd, I just observe that the machine refuses to boot anything with the ssd plugged in
2012-06-30T18:14:26 < cjbaird> Just as well, as the TSA would be wanting to go through the SSD's contents when you return.
2012-06-30T18:14:42 < zyp> no, they won't

2012-06-30T18:16:30 < zyp> I'm not from the US, so I don't have to deal with that shit
2012-06-30T18:18:36 < zyp> oh well, I didn't have anything important on the ssd, so it's no big deal if the contents are lost
2012-06-30T18:19:16 < zyp> and it's still under warranty, so I should get it replaced for free as well
2012-06-30T18:23:58 < cjbaird> We get the "We're Customs! We can look at -everything- coming into the country!" here in Australia.. People get busted for having porn on laptops/phones/memory cards all the time :/, even the stuff that would be legal to bring in if it were on paper..
2012-06-30T18:26:36 < zyp> so far I've never been stopped in customs when flying home to norway
2012-06-30T18:27:44 <+Steffanx> Norway isn't Australia nor the US :)
2012-06-30T18:27:47 <+Steffanx> They're sick
2012-06-30T18:27:56 < zyp> yeah, I've heard rumors
2012-06-30T18:28:34 <+Steffanx> There's here something on TV about the Australian customs .. sometimes i think "WTF" when I watch that
2012-06-30T18:29:14 < zyp> the only thing I'm afraid of with customs is that they'll hassle me about import tax
2012-06-30T18:31:13 < zyp> the exempt limit is 6000 nok (about $1000) or so, and I've got both laptops and camera shit worth more than that, that I in theory have to prove I didn't buy during my vacation
2012-06-30T18:31:53 <+Steffanx> You can't proof it afterwards?
2012-06-30T18:32:50 < zyp> I don't lug around the receipts stating where and when I bought all the valuable items I'm carrying
2012-06-30T18:33:24 <+Steffanx> I do
2012-06-30T18:33:38 <+Steffanx> in my mailbox as i ordered most of it online
2012-06-30T18:34:10 < zyp> and I don't know how the customs officers would like «well, I bought this lens in Japan in 2008, and I probably have the receipt proving that somewhere at home»
2012-06-30T18:35:03 <+Steffanx> "Guilty until proven otherwise" ?
2012-06-30T18:37:21 < zyp> well, I don't know, as I said I've never been stopped :p
2012-06-30T18:38:38 <+Steffanx> ok, time will tell
2012-06-30T18:38:58 < zyp> I'm probably not going to be stopped this year either :p
2012-06-30T18:39:20 <+Steffanx> Laurenceb_ as master troll should give them a call
2012-06-30T18:39:31 < BrainDamage> in reality he's been stopped multiple times already
2012-06-30T18:39:38 < BrainDamage> but the experience was so traumatic he removed it
2012-06-30T18:39:49 <+Steffanx> Brain Damage
2012-06-30T18:40:41 < zyp> I've been stopped a few times for custom inspections when driving to/from sweden
2012-06-30T18:48:15 < cjbaird> The Australian 'Customs Patrol' shows are shit. The New Zealand Cop/Customs/Ranger shows are the ones that rate here.
2012-06-30T18:51:08 < cjbaird> Fun Fact: Australia never gave a fuck about Steve Irwin when he was alive (Who was of course eulugized into some National Hero[tm] after..) His shows were always ratings bombs; at least once they canceled mid-season. We could tell the guy was /fake/.

2012-06-30T19:40:33 < R2COM> i received my stm32f405rgt6 chip, the strange thing is it has two circles on each corner, i am not sure now which one is really PIN1 designator? one circle is a little bigger than another. both are stamped circles.
2012-06-30T19:41:40 < Thorn> the one near pin 1 is the right one
2012-06-30T19:41:57 < R2COM> yes. you are brilliant
2012-06-30T19:42:54 < BrainDamage> look at the datasheet, under packaging section
2012-06-30T19:43:21 < R2COM> datasheet has a drawing, with circle near pin1, but thats it
2012-06-30T19:43:29 < Thorn> if you orient the chip so that markings are upright, pin one should be in the lower left corner
2012-06-30T19:44:21 < BrainDamage> use the print to distinguish top to bottom?
2012-06-30T19:44:21 < R2COM> ok
2012-06-30T19:44:46 < R2COM> thats how it is for stm32f407 chip on discovery board
2012-06-30T19:44:56 < R2COM> so i guess I'll then consider same for this chip
2012-06-30T19:45:24 < R2COM> its just, this chip has another circle, that one is bigger, on top left corner (and text is upright)
2012-06-30T19:45:42 < R2COM> alright
2012-06-30T19:45:51 < Thorn> should be true for all qfp chips
2012-06-30T19:46:21 < Thorn> ... or maybe not. ft2232h has pin 1 in the upper left corner
2012-06-30T19:47:24 < Thorn> same with a cyclone II
2012-06-30T19:48:04 < zyp> there is no general truth there

2012-06-30T22:32:09 < jpa-> store r3 to adress r2 + 44

2012-06-30T22:34:20 < szczys> movs    r2, #1
2012-06-30T22:34:27 < szczys> moves from r2 to r3?

2012-06-30T22:50:02 < jpa-> it moves '1' to r2
2012-06-30T22:50:44 < Thorn> where did you see r3 in there
2012-06-30T22:51:37 < jpa-> 'immediate' means "plain number"
2012-06-30T23:02:09 < zippe1> szczys: your cite says "store the contents of r3 at address (r2 + 44)
2012-06-30T23:02:44 < zippe1> If you're using C, that's almost certainly a structure or array access
2012-06-30T23:03:16 < zippe1> uint32 foo[]; foo[11] = bar;
2012-06-30T23:03:48 < Thorn> or a local variable access if r2 happens to be a frame pointer
2012-06-30T23:04:01 < zippe1> Frame pointer is r7 in EABI
2012-06-30T23:04:08 < zippe1> So that's not it
2012-06-30T23:04:34 < Thorn> right but the pattern is the same
2012-06-30T23:04:39 < zippe1> Also, gcc is fairly aggressive about tracking the stack pointer, it's very rare for it to emit FP-relative ops
2012-06-30T23:05:02 < zippe1> (in fact, you can tell it not to maintain the FP and get a GPR back with -fomit-frame-pointer)
2012-06-30T23:05:18 < zippe1> FP is mostly just useful for debugging
