2012-08-01T05:58:14 < zippe> I can't even begin to understand how they screwed up the CCM so badly
2012-08-01T06:03:32 < dongs> why?
2012-08-01T06:03:34 < dongs> whats wrong with it
2012-08-01T06:09:35 < zippe> https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Attachments/22412/2012_STM32%20Technical%20Updates%20-%20Issue%201.pdf
2012-08-01T06:10:01 < zippe> Apparently "arbitration" means you're slower running code in flash, data in CCM than data in SRAM1
2012-08-01T06:10:23 < zippe> Instead of being the fast RAM, the CCM is the slow RAM
2012-08-01T06:10:51 < dongs> right :(

2012-08-01T06:43:28 < bcsllc-steve> did ST change thier site
2012-08-01T06:43:34 < bcsllc-steve> for the better ?
2012-08-01T06:43:47 < bcsllc-steve> I found all the manuals for the F0 chip on one page
2012-08-01T06:43:51 < bcsllc-steve> seemed easy
2012-08-01T06:44:22 < bcsllc-steve> real easy

2012-08-01T07:37:37 < dongs> zippe, instructions from flash via I bus, CCM via the D bus & SRAM via the SBUS. As long as you don't read data from flash, you should be ok.

2012-08-01T08:37:48 < dongs> whats a literal pool?  constants ?
2012-08-01T08:39:04 < dongs> i wonder if ccm on f3 sucks less now that it can run code
2012-08-01T08:47:28 -!- lawrenceseattle [~anonymous@216.243.49.130] has joined ##stm32
2012-08-01T08:56:59 < zippe> *blink(
2012-08-01T08:57:08 < zippe> A literal pool… is a pool of literals.
2012-08-01T08:57:28 < zippe> The ARM ISA doesn't support immediate values with many bits set.
2012-08-01T08:58:03 < zippe> So typically instead of using immediates, the compiler emits a pc-relative load and stuffs the actual constant into the space after the end of the function.
2012-08-01T08:58:28 < zyp> I still think that benchmark is a load of shit
2012-08-01T08:58:40 < zippe> It's less common with T2 due to movt being about as expensive, but still
2012-08-01T08:58:46 < zippe> zyp: it's totally synthetic
2012-08-01T08:59:06 < zippe> zyp: I'm just still amused that they could screw up their arbitration so much that they can actually measure a delay.
2012-08-01T08:59:36 < zyp> yeah, I was also confused about that part
2012-08-01T09:00:40 < zyp> I don't get why one master switching between several slaves need to cause a delay
2012-08-01T09:03:05 < zyp> and even then it should be dwarfed by the delay caused by several masters trying to access one slave

2012-08-01T09:07:42 < dongs> zippe: thats what i meant.
2012-08-01T09:08:09 < dongs> zippe: so those are constants, and they're read from flash right.
2012-08-01T09:08:32 < zyp> yes
2012-08-01T09:50:27 < dongs> http://www.youtube.com/watch?v=BsGjWJAu2rI holy fucking TTS batman
2012-08-01T09:54:18 -!- Claude is now known as claude
2012-08-01T10:07:37 < zippe> zyp: they may have done something retarded like a round-robin arbiter with limited empty queue skipping
2012-08-01T10:08:39 < zippe> zyp: but in all honesty, I'd have expected they'd just click the button that says PL301, edited the config and hit 'make'
2012-08-01T10:09:10 < zyp> there is not like CCM access have to be arbitrated anyway, it's single master only
2012-08-01T10:09:38 < zippe> zyp: well, the M3 doesn't have three ports on the bottom
2012-08-01T10:09:49 < zippe> So I, D and S are fabric concepts
2012-08-01T10:10:06 < zippe> Arbiter slots, effectively
2012-08-01T10:10:20 < zippe> But that's where it's a bit weird
2012-08-01T10:10:53 < zippe> Anyway, not like it matters beyond academia
2012-08-01T10:10:59 < zippe> I'll ask them if I ever get a chance
2012-08-01T10:11:22 < dongs> killing that performance

2012-08-01T15:58:16 < jpa-> i wonder why make & chibios makefile is terribly slow under windows & mingw32
2012-08-01T15:58:35 < jpa-> it's doing some fancy header dependency tracking with gcc, but it works much faster on linux
2012-08-01T16:04:20 < cjbaird> Try hitting the filesystem performance tuning blogs?
2012-08-01T16:06:58 <+dekar> jpa-, I often feel like there is something odd with GCC performance on windows
2012-08-01T16:07:19 <+dekar> though cygwin is worse than minGW
2012-08-01T16:07:22 < zyp> maybe related to cost of process spawning on windows
2012-08-01T16:07:52 < zyp> a lot of linux tools are written with cheap forks in mind
2012-08-01T16:08:46 <+dekar> zyp, I wonder how the performance is when you use native windows pthreads using the POSIX kernel extension microsoft offers
2012-08-01T16:09:09 < zyp> forks are not threads
2012-08-01T16:09:34 <+dekar> oh right, then fork peformance I guess
2012-08-01T16:09:37 < cjbaird> Is threading still the Windows/NT preference?
2012-08-01T16:10:44 <+dekar> "Microsoft POSIX subsystem, an optional Windows subsystem. Partial POSIX-1 — no threads, no sockets." http://en.wikipedia.org/wiki/POSIX#POSIX_for_Windows
2012-08-01T16:10:49 <+dekar> doesn't sound too great

2012-08-01T18:25:37 < karlp> cheapest I can find is $6.56 on digikey dongs, for 5000k 0603,
2012-08-01T18:25:42 < karlp> 0805 is a little more.
2012-08-01T18:25:47 < karlp> 5k, not 500k.
2012-08-01T18:26:28 < dongs> Ya, thats yageo
2012-08-01T18:26:33 < dongs> but right, something around that price.
2012-08-01T18:26:35 < dongs> they're cheapest.
2012-08-01T18:27:32 < karlp> for 10-50, in 0805, digikey and farnell are virtuall the same price anyway

2012-08-01T18:29:00 < karlp> I'm using 0805 because it's smallish, but reasonable for me to do by hand.
2012-08-01T18:29:10 < dongs> 0603 mostly, i've got a few projects with 0402 though
2012-08-01T18:29:32 < karlp> I reckon 0603 would have been nicer for some of these decoupling caps, to take up less of the space around the pads

2012-08-01T18:45:05 < dongs> anything above that might as well just use tantalums

2012-08-01T21:14:04 < zippe> Why are you using the assembler in the first place?
2012-08-01T21:14:06 < Rickta59> the user can change the size of the RB_SIZ

2012-08-01T21:14:30 < zippe> move the head/tail pointers to the beginning of the structure
2012-08-01T21:14:48 < zippe> That's also just good programming practice
2012-08-01T21:15:17 < zippe> If you have a collection, put all the traversal information together at the head of the collection entry
2012-08-01T21:15:19 < Rickta59> that is one solution but this is just a simple example of using structs
2012-08-01T21:15:28 < zippe> Yes
2012-08-01T21:15:37 < zippe> And as long as you don't plan on actually using the code, that's great
2012-08-01T21:15:49 < Rickta59> i'm using the code
2012-08-01T21:15:54 < zippe> in general though, you don't want to be making assumptions about structure layout in assembly code
2012-08-01T21:15:59 < zippe> Then don't use assembler
2012-08-01T21:16:14 < Rickta59> for the specific application I'm doing  it is a good thing

2012-08-01T21:16:25 < zippe> Then don't use a structure
2012-08-01T21:16:28 < zippe> Use an array
2012-08-01T21:16:38 < zippe> Structure layout is something that the compiler owns
2012-08-01T21:16:51 < zippe> You should not assume that you can know anything about how a structure is laid out, in general.
2012-08-01T21:16:59 < Rickta59> that is silly
2012-08-01T21:17:01 < zippe> Because the compiler *will* fuck you
2012-08-01T21:17:05 < zippe> No, that's how the language works
2012-08-01T21:17:32 < Rickta59> if i bend the compiler to make it laid out in a specific way then it is going to look like i expect
2012-08-01T21:17:33 < zippe> Don't go pretending that your assumptions about the language actually control how the compiler will process it
2012-08-01T21:17:51 < zippe> Ok, and how do you plan to do that?
2012-08-01T21:18:03 < Rickta59> using a specific compiler
2012-08-01T21:18:14 < Rickta59> with specific known sizes and packing
2012-08-01T21:18:24 < zippe> Yes, that's nice.  Are you going to write that compiler?
2012-08-01T21:18:30 < Rickta59> i'm talking about gcc
2012-08-01T21:18:33 < zyp> you mean a specific version of a specific compiler with specific flags?
2012-08-01T21:18:39 < Rickta59> yeah
2012-08-01T21:18:45 < zippe> Still won't help.
2012-08-01T21:19:05 < Rickta59> so you really don't know how to use the .struct directive
2012-08-01T21:19:07 < zyp> cool, enjoy having to dig up an old compiler version when you want to compiler your code in two years
2012-08-01T21:19:15 < zippe> No, I know how it works.
2012-08-01T21:19:29 < Rickta59> that is all i asked .. was if someone knows some good examples of its use
2012-08-01T21:19:30 < zippe> I'm trying to save you a bunch of grief.
2012-08-01T21:19:37 < zippe> There aren't any good examples of its use.
2012-08-01T21:19:44 < zippe> It is not a good thing to use.
2012-08-01T21:19:48 < zippe> Don't use it.
2012-08-01T21:19:53 < Rickta59> thanks
2012-08-01T21:20:04 < Rickta59> either way i still have to deal with it
2012-08-01T21:20:07 < zippe> Do not assume that you can know how a structure is laid out by the compiler.
2012-08-01T21:20:14 < Rickta59> if i compile it
2012-08-01T21:20:19 < Rickta59> and look at the structure it creates
2012-08-01T21:20:23 < Rickta59> then i know what it looks like
2012-08-01T21:20:29 < zippe> Then you know how it looked when you compiled it.
2012-08-01T21:20:33 < zippe> That's nice, but it doesn't help you.
2012-08-01T21:20:38 < Rickta59> and it is going to change when?
2012-08-01T21:20:52 < zippe> If the compiler changes its mind about how it wants to pack the structure.
2012-08-01T21:20:58 < Rickta59> why would it do that?
2012-08-01T21:21:04 < zippe> Lots of reasons
2012-08-01T21:21:08 < Rickta59> give me one
2012-08-01T21:21:18 < zyp> new optimization rules
2012-08-01T21:21:22 < zippe> The optimiser might decide that changing field alignment would improve performance.
2012-08-01T21:21:43 < zippe> It might decide that it can eliminate one or more members of the structure.
2012-08-01T21:21:53 < Rickta59> all members are used
2012-08-01T21:22:05 < Rickta59> in all cases of the code
2012-08-01T21:22:09 < zippe> Your definition of "used" and the compilers' are not the same.
2012-08-01T21:22:27 < zippe> Especially when whole-program optimisation comes into play.
2012-08-01T21:22:30 < zyp> used members might still be optimized out to registers only
2012-08-01T21:22:34 < Rickta59> -data-sections -Wl,gc-sections does not eliminate any of my member structures
2012-08-01T21:22:53 < zippe> try -flto and then guess what happens there in another couple of years
2012-08-01T21:23:03 < zippe> Or look at what clang + lld does to your code.
2012-08-01T21:23:08 < zyp> Rickta59, so anyway, what are you really asking about?
2012-08-01T21:23:30 < Rickta59> has anyone used ".struct" in gcc asm and have a good example of how you use it?
2012-08-01T21:23:39 < zippe> Yes, and no, respectively.
2012-08-01T21:23:47 < zyp> as for me: no.
2012-08-01T21:23:55 < Rickta59> ok .. thanks
2012-08-01T21:24:08 < zippe> See above inre: there are no good examples.

2012-08-01T21:26:00 < Rickta59> I guess I will take your advice and switch my struct around so the variable part is at the end however in my 'C' version it actually makes the code larger
2012-08-01T21:26:41 < Rickta59> its access to the buffer part is quicker if it is the first member of the struct

2012-08-02T03:15:48 < dongs> now with even more flash and java
2012-08-02T03:21:35 <+dekar> Laurenceb, windows 8 sounds great, I love the tablets they showed
2012-08-02T03:22:12 <+dekar> they look like you can actually work on them, unlike those android and iOS things
2012-08-02T03:23:00 < dongs> > tablets
2012-08-02T03:23:02 < dongs> found your problem
2012-08-02T03:25:04 <+dekar> well I haven't gotten any so far
2012-08-02T03:25:22 <+dekar> but if they reach the point where they can replace my laptop, why not?

2012-08-02T03:32:59 < dongs> why hte fuck would I get a tablet with a gimped 500mhz processor, when I can just use my laptop with a real os, full set of peripherals, normal keyboard, proper processor, etc?
2012-08-02T03:34:00 <+dekar> dongs, microsoft actually showed some core i tablet with a real hardware keyboard
2012-08-02T03:37:30 <+dekar> dongs, http://www.youtube.com/watch?v=jozTK-MqEXQ&feature=player_detailpage#t=1654s
2012-08-02T03:38:18 < dongs> so how the fuck is this better than a laptop that wont fucking break in half when you open it
2012-08-02T03:38:38 < dongs> paying extra $ for detachable keyboard which I will never detach
2012-08-02T03:38:40 < dongs> makes so much sense.
2012-08-02T03:39:33 <+dekar> for things like watching movies and reading stuff you don't need the keyboard
2012-08-02T03:39:47 <+dekar> can be more convenient without
2012-08-02T03:40:19 <+dekar> why do people buy tablets these days?
2012-08-02T03:40:24 < dongs> no idea
2012-08-02T03:40:31 < dongs> its a retarded fad started by crapple
2012-08-02T03:40:40 < dongs> was hoping it would die with steve
2012-08-02T03:40:42 <+dekar> makes them billions
2012-08-02T03:40:43 < dongs> but apparnetly it didnt
2012-08-02T03:41:10 < dongs> I had a toshiba portege M400 tablet PC in like 2006
2012-08-02T03:41:27 < dongs> with wacom  tablet input surface and like 1400x1050 12" screen
2012-08-02T03:41:39 < dongs> that was infinitely more useful than any fucking garbage tablet from 2012
2012-08-02T03:41:43 <+dekar> they lacked the software back then
2012-08-02T03:41:51 < dongs> no, it runs windows 7 just fine
2012-08-02T03:41:58 < dongs> and is perfectly usable.
2012-08-02T03:42:01 <+dekar> win7 doesn't suffice
2012-08-02T03:42:16 < dongs> ????
2012-08-02T03:42:19 <+dekar> compare the android browser to IE on win7
2012-08-02T03:42:30 <+dekar> it's about the touch interface

2012-08-02T03:45:58 < dongs> anyway tablets fail, plain and simple

2012-08-02T03:46:29 <+dekar> anyway, I am open for it and I will try them once they're out. I feel like they are getting a lot more usable with those surface ones than they were before

2012-08-02T03:47:45 < zippe> dekar: The Surface fails for me on two counts.  #1, they were so desperate to pre-announce it ahead of the Nexus 7 that they went to the press with demo units that crashed on stage, and hands-on units that just didn't work.
2012-08-02T03:47:56 < zippe> dekar: and #2, two words: "peripheral venting"
2012-08-02T03:48:11 < zippe> dongs: is there money involved?
2012-08-02T03:48:13 <+dekar> zippe, didn't all windows products crash on stage? so do they in RL :P
2012-08-02T03:48:17 < dongs> zippe: absolutely
2012-08-02T03:48:29 < zippe> dongs: real money, or hobbyist money?
2012-08-02T03:48:34 < dongs> real.

2012-08-02T03:49:23 <+dekar> laptops vent as well

2012-08-02T18:17:49 < emeb> Trying to get an F405 to talk to a WM8731 codec.
2012-08-02T18:18:15 < emeb> I2S works, I2C works, MCLK works, but codec isn't outputting audio.
2012-08-02T18:18:28 < emeb> Mysterious...
2012-08-02T18:18:40 < zyp> who's the clock master?
2012-08-02T18:18:48 < emeb> F405 is the master
2012-08-02T18:19:32 < zyp> so it's running the clock but only reading all zeros?
2012-08-02T18:20:16 < emeb> I can see MCLK, SCLK, SDO, WS going to the codec - all look OK.
2012-08-02T18:20:42 < emeb> I2C control channel works - I can see codec configuring itself as commanded.
2012-08-02T18:21:08 < emeb> The analog output ramps up to AVDD/2 as it should, but no audio is there.
2012-08-02T18:21:47 < zyp> oh, wait, I read you wrong, I thought you were reading data, not writing :p
2012-08-02T18:22:42 < zyp> have you checked the validity of the data you are writing?
2012-08-02T18:23:06 < emeb> Looks right on the oscilloscope. Bits in the right places...
2012-08-02T18:23:37 < emeb> Also, no ADC data coming out of the codec - should be some lsbs toggling at least to show input noise.
2012-08-02T18:23:56 < zyp> sounds like the codec is not configured correctly
2012-08-02T18:24:33 < emeb> Yeah, but I've used this codec in many other apps (different MCUs, FPGAs) with the exact same configuration and it worked fine.
2012-08-02T18:24:56 < zyp> schematic is correct?
2012-08-02T18:25:27 < zyp> well, either the hardware is defective, configuration is wrong or data you're outputting is invalid
2012-08-02T18:25:29 < emeb> Well - correction. Different wordsizes: I've used 32-bit and 24-bit data size. 16 on the F405...
2012-08-02T18:25:52 < emeb> Yep - that pretty much sums it up.
2012-08-02T18:26:05 < emeb> Hope it's not another dead chip.

2012-08-02T20:15:05 < dongs> http://bcas.tv/paste/results/kNFif764.html
2012-08-02T20:15:07 < dongs> dafuQ??
2012-08-02T20:16:26 < zyp> ha, cute
2012-08-02T20:19:11 < dongs> that is j ust so fucking terrible
2012-08-02T20:19:17 < dongs> this is with -O2
2012-08-02T20:19:46 < dongs> same wiht -Os
2012-08-02T20:20:01 < dongs> gonna chalk this up as opeansauce being a giant steaming shitheap of failure
2012-08-02T20:20:27 < zyp> nah, it's just not optimized for 8-bit shit :p
2012-08-02T20:22:24 < zyp> sensible way to do that shit would be to move the highest reg into the lowest, swap nibbles, mask out the top nibble and clear the other three registers
2012-08-02T20:22:32 < zyp> if they are even used
2012-08-02T20:23:10 < jpa-> and this is what it could be if it were smarter http://paste.dy.fi/Zb0/plain
2012-08-02T20:23:32 < zyp> that's what I said
2012-08-02T20:23:35 < jpa-> yep
2012-08-02T20:23:59 < zyp> except you can clear registers with something smaller than ldi, can't you?
2012-08-02T20:24:11 < jpa-> dunno
2012-08-02T20:24:24 < zyp> I believe there is even a clear instruction
2012-08-02T20:25:01 < dongs> jpa, are you saying it generated that code if you did >>24>>4?
2012-08-02T20:25:24 < jpa-> and cast to uint8_t
2012-08-02T20:25:27 < jpa-> but yeah
2012-08-02T20:25:54 < zyp> so it's capable of that
2012-08-02T20:26:11 < dongs> my type was already uint8_t
2012-08-02T20:26:15 < dongs> for the shift destination
2012-08-02T20:26:20 < dongs> I shouldn't need an explicit cast I guess
2012-08-02T20:26:30 < jpa-> you need it between the shifts
2012-08-02T20:26:30 < dongs> but mine was just blah >> 28 & 0xf
2012-08-02T20:26:57 < jpa-> otherwise it just thinks "24 + 4 is 28, round and round we go 28 times!"
2012-08-02T20:27:05 < dongs> haha
2012-08-02T20:27:33 < zyp> it could probably reported as a case of missed optimization
2012-08-02T20:28:43 < dongs> missed  blogization
2012-08-02T20:28:52 < dongs> i hate avr filth
2012-08-02T20:28:54 < zyp> but I can't be assed to do it :p
2012-08-02T20:29:02 < dongs> i sure as hell wont.

2012-08-03T09:05:19 < Tectu> how big is a float on stm32?
2012-08-03T09:08:23 < jpa-> 32 bits
2012-08-03T09:08:34 < jpa-> just like everywhere else
2012-08-03T09:08:44 < Tectu> okay, and double is 64, right?
2012-08-03T09:08:59 < jpa-> yes
2012-08-03T09:09:32 < Tectu> but afaik double is somehow more precisely in how it stores decimal values than float?
2012-08-03T09:12:53 < zippe1> Tectu: No
2012-08-03T09:13:11 < Tectu> zippe1, go on?
2012-08-03T09:13:36 < zippe1> Tectu: a floating point number is a combination of a fixed-point binary value and an exponent
2012-08-03T09:13:46 < zippe1> Do those words mean anything to you?
2012-08-03T09:14:17 < zippe1> (I want to make sure I can explain this clearly)
2012-08-03T09:15:08 < Tectu> yes
2012-08-03T09:15:11 < Tectu> i understand that
2012-08-03T09:15:40 < Tectu> and thanks for checking. i like that, sometimes people start to explain stuff which is interesting, but i don't understand at all :D
2012-08-03T09:16:09 < zippe1> Ok, so assuming ieee754, which is what everyone uses, a floating point number allocates bits for the sign bit, for the exponent and for the fixed-point value (also called the significand)
2012-08-03T09:16:59 < zippe1> In the binary32 format, which is what 'float' is on STM32, there is one bit for sign, eight bits for exponent and 23 bits for the coefficient.
2012-08-03T09:17:18 < Tectu> i understand
2012-08-03T09:18:09 < zippe1> Ok, great.  So for binary64 (double), the exponent is 11 bits and the coefficient is 52 bits.
2012-08-03T09:18:30 < Tectu> so this just gives a higher resolution then?
2012-08-03T09:18:50 < Tectu> so more digits after the decimal point
2012-08-03T09:18:55 < zippe1> Effectively.  "resolution" and "precision" are used interchangeably.
2012-08-03T09:19:05 < zippe1> And, no, not more digits after the decimal point.
2012-08-03T09:19:06 < Tectu> i see
2012-08-03T09:19:11 < Tectu> why not?
2012-08-03T09:19:16 < Tectu> just a higher resolution?
2012-08-03T09:19:23 < zippe1> There is no decimal point because this is a binary number
2012-08-03T09:19:28 < zippe1> You could call it the "binary point"
2012-08-03T09:19:36 < zippe1> But there is no guarantee that there are any digits after it
2012-08-03T09:19:40 < Tectu> correct
2012-08-03T09:19:51 < Tectu> okay, so let's say i do   float foo = 0.629320391;
2012-08-03T09:19:55 < zippe1> If the exponent is greater than the number of significant bits, for example
2012-08-03T09:19:57 < zippe1> Hang on.
2012-08-03T09:20:02 < Tectu> ok
2012-08-03T09:20:50 < zippe1> The "precision" (let's use that word) of a floating point value is the ratio of any given number N and the smallest distinct number larger than N that can be represented.
2012-08-03T09:21:28 < zippe1> Let's use decimal as an example, because it's easier to think about that.
2012-08-03T09:21:35 < Tectu> okay
2012-08-03T09:21:40 < zippe1> And let's assume we are writing decimal with three significant figures.
2012-08-03T09:22:02 < zippe1> So we have 1.23.  The next largest distinct value that you can write is 1.24.
2012-08-03T09:22:23 < Tectu> correct
2012-08-03T09:22:36 < zippe1> Or we have 0.456, and the next largest value you can write is 0.457
2012-08-03T09:22:52 < Tectu> i agree
2012-08-03T09:22:55 < zippe1> or 128000, and 129000
2012-08-03T09:23:31 < Tectu> so double is the same as float, just twice as big?
2012-08-03T09:23:34 < Tectu> from the footprint
2012-08-03T09:23:45 < zippe1> A double uses twice as much memory as a float.
2012-08-03T09:24:10 < zippe1> But you can express larger numbers with it, and you can express numbers that are closer to one another with it.
2012-08-03T09:24:16 < Tectu> okay
2012-08-03T09:24:19 < Tectu> so higher resolution
2012-08-03T09:24:21 < Tectu> :D
2012-08-03T09:24:28 < zippe1> More precision. 8)
2012-08-03T09:24:33 < Tectu> i understand what you mean. Thank you very much
2012-08-03T09:24:38 < Tectu> this was helpful indeed
2012-08-03T09:24:48 < zippe1> Ok, glad to have been useful. 8)
2012-08-03T09:25:10 < Tectu> but when i do    float foo = 0.629320391;   i will have 4 bytes in my memory, and the compiler does calculate the coefficient and exponent?
2012-08-03T09:25:17 < zyp> yes
2012-08-03T09:25:26 < Tectu> and on runtime the CPU does that job?
2012-08-03T09:25:43 < Tectu> isn't that a hard task to do? :D
2012-08-03T09:25:48 < zyp> no
2012-08-03T09:25:51 < zippe1> Yes.  But you should write float foo = 0.629320391f, because 0.629320391 is a double.
2012-08-03T09:26:02 < Tectu> zippe1, how comes?
2012-08-03T09:26:13 < zippe1> Tectu: because the language standard says so.
2012-08-03T09:26:24 < Tectu> what happens with    float foo = 0.629320391;   ?
2012-08-03T09:26:31 < Tectu> it does work somehow.
2012-08-03T09:26:41 < zyp> the compiler makes a double and then casts it into a float
2012-08-03T09:26:43 < zippe1> Tectu: If your compiler is smart, it will generate a float directly.
2012-08-03T09:26:54 < Tectu> is gcc smart?
2012-08-03T09:27:31 < zippe1> Tectu: but if you write foo = foo * 7.5, it will case foo to a double, multiply it by 7.5, then cast it back to a float because the language says it must (and the answer would be different compared to foo = foo * 7.5f);
2012-08-03T09:27:37 < zippe1> s/case/cast/
2012-08-03T09:27:42 < zippe1> Tectu: usually.
2012-08-03T09:28:10 < Tectu> i see
2012-08-03T09:28:42 < Tectu> a guy contributed lcdDrawEllipse() to my GLCD library. therefore he also sent two files, fastMath.h and fastMath.c which contain some functions to get a sine value without using sin(), because he used this on AVRs (8-bit). therefore there is   float sinetable[91];  <---- 364 bytes. is it the memory worth on an STM32 or might i just use sin() here?
2012-08-03T09:29:02 < Tectu> here:  https://github.com/Tectu/ChibiOS-LCD-Driver/blob/master/glcd/fastMath.c
2012-08-03T09:29:12 < dongs> use sinf().
2012-08-03T09:29:16 < dongs> dont be a fag.
2012-08-03T09:29:22 < dongs> use float versions of all math functions.
2012-08-03T09:29:34 < dongs> they;'lk still be insanely better than 8bit shits.
2012-08-03T09:30:15 < zippe1> Tectu: Your sin() implementation is probably still going to be performing linear interpolation over a table.
2012-08-03T09:30:25 < Tectu> zippe1, which means?
2012-08-03T09:30:27 < zippe1> It's funny that someone would use a table on the AVR though
2012-08-03T09:30:34 < Tectu> zippe1, how comes?
2012-08-03T09:30:48 < zippe1> Because the avrlibc sin is already a very good table-based interpolation
2012-08-03T09:31:15 < zippe1> I spent a considerable amount of time trying to optimise it, and to get better results, and you need a *lot* of memory to do better.
2012-08-03T09:31:16 < Tectu> so you recommend using sin() by including <math.h>  ?
2012-08-03T09:31:16 < nopcode> do people use a libc on avr?
2012-08-03T09:31:31 < Tectu> nopcode, yes, they do
2012-08-03T09:31:36 < dongs> zippe, did you see the awesome avr-gcc fail I uncovered
2012-08-03T09:31:40 < zippe1> nopcode: sometimes; Joerg and code did a fantastic job with avrlibc.
2012-08-03T09:31:51 < dongs> zippe1: uint32_t dongs >> 28 = http://bcas.tv/paste/results/kNFif764.html
2012-08-03T09:31:57 < zippe1> Tectu: You're probably using newlib; the math functions there are quite OK
2012-08-03T09:33:11 < Tectu> zippe1, well, the library should be usable for everyone using ChibiOS
2012-08-03T09:33:20 < Tectu> so what if someone dosen't use newlib?
2012-08-03T09:33:41 < zyp> Tectu, then you don't use newlibs math functions, so it doesn't apply
2012-08-03T09:34:00 < Tectu> zyp, not sure if I understand what you mean
2012-08-03T09:34:13 < zippe1> Tectu: almost everyone using gcc on stm32 has newlib.
2012-08-03T09:34:26 < zippe1> Tectu: since that's the default C library that comes with the compiler
2012-08-03T09:34:51 < zippe1> Tectu: It is possible to build with no library, in which case they would need their own sin() function.
2012-08-03T09:35:14 < Tectu> zippe1, well, in that case the entire library wouldn't become compilable since there are also things like abs() etc
2012-08-03T09:35:18 < zippe1> Tectu: I would expect that chibi depends on newlib, or some equivalent library
2012-08-03T09:35:22 < Tectu> so i think i just don't care at that poing
2012-08-03T09:35:26 < Tectu> correct
2012-08-03T09:35:30 < Tectu> that's what i thought too
2012-08-03T09:36:55 < Tectu> so i don't have higher math kowledges yet, but i want to know this: when a CPU has to use float, and there is something like 0.629320391f, how does it calculate it's binary form?
2012-08-03T09:37:07 < zippe1> The compiler does that for it.
2012-08-03T09:37:12 < Tectu> not on rumtime?
2012-08-03T09:37:13 < zippe1> The process is really annoying.
2012-08-03T09:37:16 < Tectu> when I do math for example
2012-08-03T09:37:38 < zippe1> Decimal to binary floating point conversion is a very involved topic.
2012-08-03T09:37:47 < zippe1> Give me a sec; I'll dig up some references for you
2012-08-03T09:37:53 < Tectu> can/want you to explain this to me in an easy way? :D
2012-08-03T09:37:56 < Tectu> would love to.

2012-08-03T09:45:55 < Tectu> but when i call sin() using newlib for example, does it actually calculate the sine value with that forumula you learn at school or does it use lookup tables as well?
2012-08-03T09:45:59 < jpa-> nah, it uses some polynomial approximation for sine
2012-08-03T09:46:09 < Tectu> -.-
2012-08-03T09:46:11 < jpa-> dunno about newlib
2012-08-03T09:46:35 < Tectu> maybe zippe1 knows more
2012-08-03T09:46:41 < Tectu> ?
2012-08-03T09:46:52 < zippe1> Tectu: fixed-point math
2012-08-03T09:47:02 < zippe1> Tectu: look at the source
2012-08-03T09:47:22 < jpa-> http://code.google.com/p/libfixmath/source/browse/trunk/libfixmath/fix16_trig.c#80
2012-08-03T09:49:04 < zippe1> sin() here:
2012-08-03T09:49:05 < zippe1> http://sourceware.org/cgi-bin/cvsweb.cgi/src/newlib/libm/mathfp/s_sine.c?rev=1.1.1.1&content-type=text/x-cvsweb-markup&cvsroot=src
2012-08-03T09:50:27 < jpa-> looks like both of them use taylor series.. except something funny about the "fast" version in libfixmath
2012-08-03T09:50:45 < zippe1> The difference is just that fixmath works on fixed-point numbers
2012-08-03T09:51:08 < Tectu> #ifndef _DOUBLE_IS_32BITS
2012-08-03T09:51:12 < Tectu> ?!
2012-08-03T09:51:32 < zippe1> You can build the library configured for double = 32-bit
2012-08-03T09:51:48 < zippe1> That helps on e.g. 8bit systems
2012-08-03T09:51:49 < Tectu> makes sense where?
2012-08-03T09:51:52 < Tectu> ah
2012-08-03T09:52:06 < zippe1> I've done it for ARM, but it's annoying
2012-08-03T09:52:12 < zippe1> And it doesn't win you a whole lot
2012-08-03T09:52:17 < Tectu> what did you do it for on ARM?
2012-08-03T09:52:21 < Tectu> and what is the annoying result?
2012-08-03T09:52:31 < zippe1> It looks like the newlib libm is another derivative of the Sun libm
2012-08-03T09:53:14 < zippe1> It's annoying to maintain, and gcc doesn't deal well with more than one libc.  You have to hack it into the multilibs but then you have to key it off the gcc option and it all just gets to be a pain
2012-08-03T09:53:38 < Tectu> what was your use for that?
2012-08-03T09:53:42 < jpa-> it can help if some 3rd party library just calls sin() all the time while you only need float precision
2012-08-03T09:54:18 < Tectu> okay
2012-08-03T09:54:39 < Tectu> can i say that a lookup table is aaaalways faster than calculating it, for example using the taylor series?
2012-08-03T09:56:04 < jpa-> it depends :)
2012-08-03T09:56:13 < Tectu> of course... :D
2012-08-03T09:56:15 < Tectu> on what?
2012-08-03T09:56:18 < jpa-> if you want good precision with a lookup table, you need some quite fancy interpolation
2012-08-03T09:57:28 < Tectu> well, back to my use case: i can just take sin() here since it only works with chibiOS which uses newlib or similar too?
2012-08-03T09:57:32 < zyp> or a pretty huge lookup table
2012-08-03T09:57:40 < zippe1> Tectu: Should be fine
2012-08-03T09:57:50 < Tectu> thanks
2012-08-03T09:58:03 < jpa-> Tectu: not everyone has sin() with chibios
2012-08-03T09:58:20 < jpa-> but then again, you don't need to care about everyone (about me :(
2012-08-03T09:58:23 < Tectu> when designing things like that, how do people choose between lookuptable vs. calculating it?
2012-08-03T09:58:33 < zippe1> Tectu: most people just use what their tools vendor supplies
2012-08-03T09:58:38 < Tectu> jpa-, just write into the docs/depencies that it is needed?
2012-08-03T09:58:48 < zyp> a full 32-bit lookup table is just 16 GiB, and then no interpolation is needed
2012-08-03T09:58:50 < Tectu> well, compiler would throw error when calling lcdDrawEllipse() then, i guess
2012-08-03T09:59:06 < zippe1> It will fail at link
2012-08-03T09:59:14 < zyp> just get a microsd and store it!
2012-08-03T09:59:51 < Tectu> interpolation is some smoothing algorithm i guess?
2012-08-03T10:00:31 < zippe1> Say you have a table that says that for input 1, you get output 5, and for input 3, you get output 10
2012-08-03T10:00:53 < zippe1> And assume that you have 2 as your input
2012-08-03T10:01:40 < zippe1> You can draw the table values on a 2d graph, or visualise it, that might help
2012-08-03T10:01:53 < zippe1> The simplest interpolation is linear.
2012-08-03T10:02:32 < zippe1> You say the values inbetween 1 and 3 should be on or near the line between 1,5 and 3,10.  So for 2 as an input, you can say that 7.5 is a good approximation of the output
2012-08-03T10:03:01 < Tectu> i understand :)
2012-08-03T10:03:22 < Tectu> of course you can go into endless optimization algorithms there too
2012-08-03T10:03:26 < zippe1> Ok, so every other interpolation technique is about making the approximation better.
2012-08-03T10:03:51 < zippe1> You can say "the line should be more like a polynomial", and use more than 2 values from the table
2012-08-03T10:04:20 < Tectu> so you say it is more like a circle than a straight line and calculate the offset then?
2012-08-03T10:04:27 < Tectu> the line between the two given points, i mean
2012-08-03T10:04:30 < zippe1> Then you fit a polynomial to the part of the table you care about, and then calculate the polynomial for the given input
2012-08-03T10:04:38 < zippe1> That's another approach
2012-08-03T10:04:48 < zippe1> Circles are bad for trig fitting though
2012-08-03T10:04:59 < zippe1> Since they only work well near the minima/maxima
2012-08-03T10:05:19 < zippe1> A third-order polynomial fit is pretty common
2012-08-03T10:05:43 < Tectu> o0
2012-08-03T10:05:45 < Tectu> how comes?
2012-08-03T10:05:47 < Tectu> that with the circles
2012-08-03T10:05:52 < Tectu> knowing pi -> no problem?
2012-08-03T10:06:12 < zippe1> Imagine trying to fit a circle to the part of a sin() curve around zero

2012-08-03T10:06:27 < zippe1> The radius of the circle would be very, very big.
2012-08-03T10:06:33 < zippe1> probably too big for you to represent
2012-08-03T10:07:37 < Tectu> ah, i see what you mean
2012-08-03T10:09:12 < zippe1> dongs: I asked some folks that know him better about CT. They seemed to think what you described was not terribly surprising.
2012-08-03T10:09:30 < zippe1> dongs: also note, DefCon
2012-08-03T10:09:46 < dongs> yeah. also: http://www.ioactive.com/news-events/IOAFlyLogic12PR.html
2012-08-03T10:10:09 < Tectu> anyone here know how to implement a spline drawing function? :D
2012-08-03T10:10:15 < zippe1> Wahahaha.  Heh.
2012-08-03T10:10:23 < Tectu> or got a good fancy link about it, describing code, not math
2012-08-03T10:10:31 < dongs> tectu, what the fuck are you doing. is your shit gonna be relevant to my OSD stuff
2012-08-03T10:11:01 < Tectu> dongs, i am writing on an GLCD library
2012-08-03T10:11:09 < Tectu> it has 14'000 lines now
2012-08-03T10:11:23 < dongs> http://www.youtube.com/watch?v=3b2e7kTVvDE will it be useful for this
2012-08-03T10:11:38 < dongs> do you have: font/bitmap rotation?
2012-08-03T10:12:09 < Tectu> dongs, not yet, my asian guy is working on that
2012-08-03T10:12:22 < Tectu> there is nothing fancy yet
2012-08-03T10:12:25 < Tectu> just complete HAL
2012-08-03T10:12:30 < Tectu> and drawing primitives
2012-08-03T10:12:41 < dongs> well i got primitives done
2012-08-03T10:12:47 < dongs> are you drawing to framebuffer?
2012-08-03T10:12:49 < dongs> or directly to lcd
2012-08-03T10:12:51 < dongs> 1bit I guess?
2012-08-03T10:13:04 < Tectu> dongs, the library is to interface LCD controllers
2012-08-03T10:13:09 < Tectu> where you mosty write into their RAM
2012-08-03T10:13:14 < Tectu> over FSMC or GPIO/SPI
2012-08-03T10:13:28 < Tectu> mostly RGB565
2012-08-03T10:13:41 < dongs> useless then
2012-08-03T10:13:49 < dongs> i want leet optimized 1bit stuff
2012-08-03T10:13:54 < dongs> and im too dumb to do it myself
2012-08-03T10:14:02 < dongs> matrix rotation???? WTF IS THAT
2012-08-03T10:14:14 < Tectu> dongs, what do you have for primitives?
2012-08-03T10:14:23 < Tectu> i only have very basic ones, not even triangles
2012-08-03T10:14:31 < Tectu> only circles, rectangles, lines, ellipses
2012-08-03T10:14:35 < dongs> Tectu: general line, optimized h/v line, circles/filled circles
2012-08-03T10:14:45 < Tectu> no ellipse, sir?
2012-08-03T10:14:48 < dongs> nope
2012-08-03T10:14:54 < dongs> circles are like... using no math
2012-08-03T10:14:54 < Tectu> why not?
2012-08-03T10:15:01 < Tectu> lol
2012-08-03T10:15:16 < dongs> ripepd the circle code from ATMEL SOFTWARE FRAMEWORK

2012-08-03T10:15:42 < Tectu> can you share your circle drawing algo?
2012-08-03T10:15:48 < Tectu> lol

2012-08-03T10:16:38 < Tectu> dunno which of ours is moar fancy
2012-08-03T10:16:43 < Tectu> faster
2012-08-03T10:17:11 < Tectu> maybe zippe1 knows more again :D
2012-08-03T10:17:21 < dongs> it seems both of our shits are identical
2012-08-03T10:17:27 < dongs> except i can configure which quadrants to draw or not
2012-08-03T10:17:41 < Tectu> "octan_mask"
2012-08-03T10:17:49 < dongs> or octants wahtever yeah
2012-08-03T10:17:55 < Tectu> dongs, i think about implementing some  uint16_t degrees
2012-08-03T10:18:05 < Tectu> but not smart enought yet
2012-08-03T10:18:40 < dongs> Hmm
2012-08-03T10:18:44 < dongs> your ellipse doesnt have math either?
2012-08-03T10:18:48 < Tectu> lol dude your impelemntation is funny
2012-08-03T10:18:49 < dongs> i think ill rip that
2012-08-03T10:18:55 < dongs> cause my osd is like 400x200
2012-08-03T10:19:02 < dongs> so I will acutgally need to squish most stuff
2012-08-03T10:19:05 < dongs> for square pixels
2012-08-03T10:19:16 < dongs> though I dont really expect to draw a lot of circles
2012-08-03T10:19:40 < Tectu> yes, i just think it's funny, the   if() stuff for each octal...
2012-08-03T10:19:47 < Tectu> never saw something funnier in my life...
2012-08-03T10:19:59 < dongs> tectu, it worsk if you dont wanna draw a full circle
2012-08-03T10:20:28 < Tectu> dongs, why don't you implement a 0 to 360° thing
2012-08-03T10:20:32 < Tectu> so you can draw circle segments
2012-08-03T10:20:43 < dongs> http://www.youtube.com/watch?v=aS4kVR5JN3o then you can do fun shit like this: http://www.youtube.com/watch?v=aS4kVR5JN3o see hte bouncing ball

2012-08-03T10:20:50 < dongs> I think that needs math
2012-08-03T10:20:53 < dongs> tectu, of course
2012-08-03T10:21:03 < dongs> why reinvent teh wheel when someone else already invented it

2012-08-03T10:30:03 < dongs> renderSpan = implement this

2012-08-03T10:30:08 < dongs> done
2012-08-03T10:30:19 < dongs> then run mainvector()
2012-08-03T10:30:57 < Tectu> i just have to implement renderSpan() and swapBuffers() ?
2012-08-03T10:31:01 < dongs> yes
2012-08-03T10:31:11 < Tectu> what thel hell is renderSpan()
2012-08-03T10:31:15 < Tectu> span?
2012-08-03T10:31:16 < dongs> .. horizonal line
2012-08-03T10:31:23 < dongs> of given width
2012-08-03T10:31:24 < dongs> thats all
2012-08-03T10:31:29 < Tectu> wtf?
2012-08-03T10:31:34 < Tectu> so just use lcdDrawLine() here?
2012-08-03T10:31:40 < dongs> yes
2012-08-03T10:31:45 < dongs> though you should optimize it probably
2012-08-03T10:31:45 < Tectu> wait, it uses horizontal lines to draw a rotating cube?
2012-08-03T10:31:48 < dongs> yes
2012-08-03T10:31:53 < dongs> its a proper 3d engine
2012-08-03T10:31:59 < Tectu> can you explain?
2012-08-03T10:32:03 < dongs> fuck no
2012-08-03T10:32:20 < zyp> straight lines, not horisontal
2012-08-03T10:32:30 < zyp> it's pretty easy
2012-08-03T10:32:32 < dongs> yes horizontal...
2012-08-03T10:32:44 < dongs> wtf is a "straight line"
2012-08-03T10:33:15 < zyp> you just have some kind of perspective matrix that translates 3d coordinates to 2d, I guess
2012-08-03T10:33:21 < zyp> similar to how opengl works
2012-08-03T10:33:46 < Tectu> does your ILI932 have a framebuffer?
2012-08-03T10:33:52 < Tectu> how am i supposed to implement this on my side?
2012-08-03T10:33:55 < dongs> in fsmc mode sure
2012-08-03T10:33:56 < Tectu> don't have such a thing
2012-08-03T10:34:01 < Tectu> how about GPIO here
2012-08-03T10:34:07 < dongs> i draw into framebuffer in my code
2012-08-03T10:34:10 < dongs> just draw directly to lcd
2012-08-03T10:34:12 < dongs> in render span
2012-08-03T10:34:16 < dongs> you'll have some tearing or whatever
2012-08-03T10:34:17 < dongs> but shrug
2012-08-03T10:34:25 < dongs> you really should just doublebuffer
2012-08-03T10:34:34 < Tectu> so i don't call swapBuffers and directly call lcdDrawLine() in renderSpan() ?
2012-08-03T10:34:35 < dongs> render to ram -> copy it off
2012-08-03T10:34:38 < dongs> yeah
2012-08-03T10:34:43 < dongs> it'll be ugly but you will see it working
2012-08-03T10:34:46 < Tectu> dongs, how much of RAM does it use?
2012-08-03T10:34:58 < dongs> the actual algo? almost nothing, your framebuffer is the problem
2012-08-03T10:35:17 < Tectu> is an F1 capable of rendering this cube with a fluid amount of FPS?
2012-08-03T10:35:25 < dongs> yes, one of my osd videos is doing it
2012-08-03T10:35:36 < dongs> and its drawing it during the vblank period
2012-08-03T10:35:50 < dongs> http://www.youtube.com/watch?v=D1yeJZDW_QA
2012-08-03T10:36:14 < Tectu> well, framebuffer would be  320*240*2 in my case?
2012-08-03T10:36:30 < dongs> i guess so
2012-08-03T10:36:45 < dongs> which is way too much even for F4.
2012-08-03T10:36:54 < Tectu> right
2012-08-03T10:37:00 < Tectu> so how to do it the right way in my case?
2012-08-03T10:37:14 < dongs> just drawline in renderspan.
2012-08-03T10:37:31 < Tectu> with getting 5FPS then?
2012-08-03T10:37:36 < dongs> nope
2012-08-03T10:37:43 < Tectu> but?
2012-08-03T10:37:47 < Tectu> 10?
2012-08-03T10:37:50 < dongs> it'll be as fast as your shit can go over wahtever interface youre using
2012-08-03T10:37:54 < dongs> could be over 9000.
2012-08-03T10:37:58 < Tectu> lol
2012-08-03T10:38:06 < dongs> in my demo the biggest problem is the SPI>LCD interface
2012-08-03T10:38:12 < dongs> actual math takes almost nothing
2012-08-03T10:38:21 < Tectu> i guess i will do beter with 16bit GPIO where it is on the same GPIO Port

2012-08-03T13:29:37 <+dekar> cjbaird, is that stuff hard to setup?
2012-08-03T13:29:47 <+dekar> I feel like I want more power all the time
2012-08-03T13:29:57 <+dekar> and we have some wicket 8 core servers at the company
2012-08-03T13:30:01 <+dekar> *wicked
2012-08-03T13:32:34 < cjbaird> ddistcc is probably easier than a lot of other things I've tried (Beowulf..) Install distccd on the servers, config /etc/distcc/hosts on the client, and a lot of the time it's just "CC=distcc make"
2012-08-03T13:33:24 < cjbaird> "CC=distcc make -jN", rather
2012-08-03T13:37:24 < Tectu> can someone tell me why there is undefined reference to cos, sin, sqrt  when i have  #include <math.h> ?
2012-08-03T13:37:27 < Tectu> using ChibiOS
2012-08-03T13:38:13 < Tectu> is there some makefile magic needed to use math.h?
2012-08-03T13:38:22 < Tectu> or has newlib some other headers for those functions?
2012-08-03T13:39:14 <+dekar> does anyone know capacitive touch controllers what work well with linux?

2012-08-03T13:42:09 < Tectu> i3 is afaik without DE

2012-08-03T14:04:03 < dongs> Tectu: ??
2012-08-03T14:04:21 < dongs> you only implement renderspan then just call vectorcubemain() which will while(1)
2012-08-03T14:04:24 < dongs> thats all.
2012-08-03T14:04:29 < Tectu> yeah, dosen't work here
2012-08-03T14:04:32 < Tectu> LCD works
2012-08-03T14:04:35 < Tectu> but blank screen
2012-08-03T14:04:38 < Tectu> no crash
2012-08-03T14:05:55 < Tectu> dongs,   http://pastebin.com/CiwZ6ZFF
2012-08-03T14:05:55 < Tectu> line 58
2012-08-03T14:06:06 < Tectu> also adjusted line 15/16
2012-08-03T14:06:27 < Tectu> calling renderCube() (line 278) works, the LCD clears
2012-08-03T14:06:31 < Tectu> then nothgin gets displayd
2012-08-03T14:06:40 < Tectu> i linked with   -lm   to use sin, cos and sqrt
2012-08-03T14:06:45 < dongs> ...
2012-08-03T14:06:49 < dongs> lcdDrawLine(x, y, x+length, y, White);
2012-08-03T14:06:51 < dongs> White? really?
2012-08-03T14:07:00 < dongs> so why are you complaining your entire lcd is white?
2012-08-03T14:07:12 < Tectu> the entire LCD is black
2012-08-03T14:07:19 < Tectu> well, dosen't work with color as well
2012-08-03T14:07:44 < dongs> get rid of lcdclear
2012-08-03T14:08:03 < Tectu> when removing that, it dosen't work as well
2012-08-03T14:08:05 < Tectu> tried that before
2012-08-03T14:08:48 < dongs> totally works here
2012-08-03T14:08:50 < dongs> youre doing something wrong
2012-08-03T14:08:57 < Tectu> idea what?
2012-08-03T14:09:11 < Tectu> what about line 15,16,17
2012-08-03T14:09:21 < Tectu> shoudl work?
2012-08-03T14:09:43 < dongs> well bpp doesnt matter
2012-08-03T14:09:48 < dongs> only width/height does
2012-08-03T14:10:03 < Tectu> that's the width and height of the LCD in pixels, right
2012-08-03T14:10:24 < dongs> what made you think it was neccessary to remove min/max?
2012-08-03T14:10:44 < Tectu> that's some math library implementation?
2012-08-03T14:11:22 < Tectu> compilers means conflicting types for 'max' and 'min'
2012-08-03T14:11:40 < dongs> anyway, dont see why it wouldnt work
2012-08-03T14:12:35 < Tectu> dongs, arent min() and max() the same as math.h provideS?
2012-08-03T14:12:54 < Tectu> dongs, probably found the problem
2012-08-03T14:13:54 < Tectu> cool, works now
2012-08-03T14:13:56 < Tectu> just to fast speed
2012-08-03T14:14:13 < dongs> heh
2012-08-03T14:14:19 < dongs> waht was it
2012-08-03T14:16:37 < Tectu> min/max
2012-08-03T14:16:40 < Tectu> :D
2012-08-03T14:16:50 < Tectu> well, it work now, somehow
2012-08-03T14:17:04 < Tectu> there is the cube, but it has a few pixels arround it which aren't getting cleared
2012-08-03T14:17:12 < Tectu> like a cloud arround the cube
2012-08-03T14:18:09 < Tectu> but only at the bottom half of it

2012-08-03T17:14:21 < Tectu> does that mean it dosen't have over other interfaces? o0
2012-08-03T17:14:36 < dongs> tectu, ili has lcd ram but not double buffered
2012-08-03T17:14:44 < dongs> noen of the cheap trash does.
2012-08-03T17:14:53 < Tectu> yeah
2012-08-03T17:14:56 < Tectu> so how did you do it?
2012-08-03T17:14:57 < dongs> what i mean is over fsmc it looks mostly like ram
2012-08-03T17:15:23 < Tectu> but do you stream the date to your LCD or do you store it inside your STM ram?
2012-08-03T17:15:29 < dongs> yes
2012-08-03T17:15:33 < dongs> the latter
2012-08-03T17:15:36 < Tectu> i guess you don't have enought RAM inside your µC to store a frame?!
2012-08-03T17:15:46 < Tectu> you need 128*128*2 in your case?!
2012-08-03T17:15:50 < Tectu> that's over 20kB
2012-08-03T17:15:54 < dongs> the cube is rendered into 128x128
2012-08-03T17:16:06 < dongs> which one, the OSD demo?
2012-08-03T17:16:11 < dongs> osd uses 1bit framebuffer
2012-08-03T17:16:18 < dongs> 400/8*200 bytes
2012-08-03T17:16:21 < Tectu> where is the sense of that?
2012-08-03T17:16:35 < dongs> the sense is it only takes 10k of ram
2012-08-03T17:16:48 < dongs> and i clock it out over spi
2012-08-03T17:16:50 < Tectu> well, but  128x128x2 bytes are still 32kB of RAM which I would need inside my STM32?
2012-08-03T17:16:51 < dongs> with minimal effort
2012-08-03T17:17:12 < Tectu> but 1bit buffer=è
2012-08-03T17:17:15 < Tectu> ?!*
2012-08-03T17:17:21 < Tectu> that's just like no buffer
2012-08-03T17:17:26 < dongs> 1bpp
2012-08-03T17:17:27 < dongs> christ
2012-08-03T17:17:30 < Tectu> aaah!
2012-08-03T17:17:31 < dongs> you are so sufcking slowp
2012-08-03T17:17:39 < dongs> < dongs> 400/8*200 bytes
2012-08-03T17:17:42 < Tectu> so you you drop the color stuff?
2012-08-03T17:17:55 < dongs> on teh fucking osd yes because i casn only do white or black anyway
2012-08-03T17:18:17 < dongs> on color cube demo i was rendering to 128x128*2 buffer
2012-08-03T17:18:21 < dongs> then displaying it in the lcd.
2012-08-03T17:18:55 < Tectu> extern uint16_t FrameBuffer[128 * 128];
2012-08-03T17:19:10 < Tectu> that's 16k?!
2012-08-03T17:19:18 < dongs> yea and?
2012-08-03T17:19:23 < dongs> it was on f4 with 192k.
2012-08-03T17:19:27 < Tectu> oh
2012-08-03T17:19:39 < Tectu> let me check how many my STM32F103VET has
2012-08-03T17:20:00 < Tectu> ILI932x_draw_framebuffer(FrameBuffer, 128, 128);
2012-08-03T17:20:04 < Tectu> can you provide?
2012-08-03T17:20:06 < dongs> 64k
2012-08-03T17:20:21 < dongs> mine is on SPI
2012-08-03T17:20:24 < dongs> you said  yours was on wide gpio
2012-08-03T17:20:27 < dongs> would bt totally irrelevant
2012-08-03T17:22:16 < Tectu> why did i always thought my F103VET does have 16k
2012-08-03T17:22:33 < dongs> 20k is minimum shit from medium density and up
2012-08-03T17:22:35 < dongs> anything higher has more.
2012-08-03T17:24:35 < Tectu> so I don't have any problems storing it
2012-08-03T17:25:22 < Tectu> <dongs> on color cube demo i was rendering to 128x128*2 buffer
2012-08-03T17:25:31 < dongs> yes
2012-08-03T17:25:32 < dongs> on F4
2012-08-03T17:25:34 < Tectu> wait
2012-08-03T17:25:40 < Tectu> <dongs> < dongs> 400/8*200 bytes
2012-08-03T17:25:45 < dongs> OSD on F103
2012-08-03T17:25:49 < dongs> 2 different projects
2012-08-03T17:25:49 < Tectu> not sure where the 400/8 comes from
2012-08-03T17:25:53 < dongs> the 1bpp part.
2012-08-03T17:26:11 < Tectu> but 16bbp (full color) would be 2 bytes
2012-08-03T17:26:13 < Tectu> so why not /2 ?
2012-08-03T17:26:14 < Tectu> o0
2012-08-03T17:26:26 < dongs> wtf dude
2012-08-03T17:26:29 < dongs> its 2 separate projects
2012-08-03T17:26:31 < Tectu> yes, i think the same
2012-08-03T17:26:32 < dongs> 1) color  cube on f4
2012-08-03T17:26:36 < dongs> 2) b&w cube on f103
2012-08-03T17:26:43 < dongs> f4 = 16bpp
2012-08-03T17:26:45 < dongs> f103 = 1bpp
2012-08-03T17:27:03 < Tectu> what does bpp stand for anyways
2012-08-03T17:27:08 < Tectu> it's the color depth, right?
2012-08-03T17:27:11 < dongs> BITS PER FUCKING PIXEL
2012-08-03T17:27:12 < dongs> yes
2012-08-03T17:27:22 < dongs> so 1bpp = I can fit 8 pixels in a bytre
2012-08-03T17:27:39 < Tectu> if you pack it the right way
2012-08-03T17:27:44 < dongs> and I do
2012-08-03T17:28:22 < Tectu> well, when i want to store the 128*128*2 area, so 16bpp, i'd still need 32k
2012-08-03T17:28:29 < dongs> yes.
2012-08-03T17:28:51 < dongs> you could do clever shit, since lcd has its own ram.
2012-08-03T17:28:56 < Tectu> can i read out ram usage over GDB? :D
2012-08-03T17:28:59 < dongs> you can keep track of whats rendered and only update whats needed.
2012-08-03T17:29:11 < Tectu> dongs, awesome when using the lightning
2012-08-03T17:30:13 < Tectu> there would be 99% changed
2012-08-03T17:30:23 < Tectu> <Tectu> can i read out ram usage over GDB? :D
2012-08-03T17:30:31 < dongs> ram usaeg of what
2012-08-03T17:30:47 < dongs> objsize or whatever tells you how much static ram you are using
2012-08-03T17:30:47 < Tectu> dunno, just break the program and check how many RAM is used
2012-08-03T17:30:59 < dongs> are you even d oing any dynamic allocation?
2012-08-03T17:31:27 < Tectu> would use malloc from ChibiOS
2012-08-03T17:31:40 < Tectu>    text	   data	    bss	    dec	    hex	filename
2012-08-03T17:31:40 < Tectu>   20156	    320	   5156	  25632	   6420	build/gui.elf
2012-08-03T17:31:44 < Tectu> that you meant?
2012-08-03T17:31:58 < zyp> yes, static ram usage is data+bss
2012-08-03T17:32:31 < Tectu> what is dec/hex?  the total amount of the image?  so text + data + bss?
2012-08-03T17:32:42 < zyp> yes
2012-08-03T17:32:48 < Tectu> so 25k here?
2012-08-03T17:32:58 < zyp> it's not relevant
2012-08-03T17:33:03 < Tectu> well, that's the elf
2012-08-03T17:33:09 < Tectu> it will only flash about 8k, right?
2012-08-03T17:33:21 < Tectu> because elf containt the entire debug stuff
2012-08-03T17:33:23 < zyp> no, it will flash text+data
2012-08-03T17:33:26 < Tectu> symbollist or whatever
2012-08-03T17:33:40 < Tectu> but when i flash that image, it says something about +8k written
2012-08-03T17:35:40 < Tectu> ?
2012-08-03T17:36:03 < Tectu> text + data is about 20500 bytes here
2012-08-03T17:36:05 < Tectu> nothing with 8k
2012-08-03T17:37:49 < Tectu> well, another question.   where data contains the global and static variables which are initialized, bss contains the unitialized ones, right?
2012-08-03T17:37:50 < zyp> I have no idea what you are going on about
2012-08-03T17:38:01 < zyp> yes, bss is zero-initialized
2012-08-03T17:38:05 < Tectu> so   int i =10;  <--- data         int i;   <-- bss
2012-08-03T17:38:12 < Tectu> yeah, but where is the sense of splitting that?
2012-08-03T17:38:25 < Tectu> why not butting bss in data and give it some 0 value when "assembling" the image
2012-08-03T17:38:32 < zyp> so you don't have to store 5k of zeros in flash
2012-08-03T17:39:22 < Tectu> ah, the zero-inizialized only happens when "starting" the image?
2012-08-03T17:39:29 < Tectu> they don't store each zero?

2012-08-03T17:54:15 < Tectu> i agree
2012-08-03T17:54:30 < Tectu> can anyone explain me why this happens on architectures like sparc etc?
2012-08-03T17:54:42 < dongs> sparc obsoletes itself
2012-08-03T17:54:46 < dongs> by doing shit like that
2012-08-03T17:54:51 < Tectu> let's say you have a 32-bit architecture, and you do 2x 32-bits packed
2012-08-03T17:54:53 < Tectu> where is the problem?
2012-08-03T17:55:03 < dongs> because its already packed
2012-08-03T17:55:14 < Tectu> why dosen't the compiler check and ignore?

2012-08-03T18:48:50 < zippe1> Tectu: The "packed" attribute doesn't work the way most people think it does
2012-08-03T18:49:15 < zippe1> When applied to a structure, it means the structure is or can be packed into a parent container.
2012-08-03T18:49:27 < zippe1> So the compiler can't assume that the structure is well-aligned.
2012-08-03T18:49:41 < zippe1> If what you want is a tightly-packed structure, use #pragma pack
2012-08-03T18:49:55 < zippe1> Or, order the fields in your structure from largest to smallest

2012-08-03T19:20:54 < jpa-> i use sdcc for pics
2012-08-03T19:21:37 < pileopython> I was using it for the 8051 and I pretty much vowed to never work with a processor that wasnt gcc supported
2012-08-03T19:23:36 < jpa-> yeah, it's pretty limited
2012-08-03T19:23:52 < jpa-> beats assembler any day, but don't expect to compile any serious C code
2012-08-03T19:31:07 <+Steffanx> I also used sdcc for pics once ..

2012-08-03T19:35:46 < jpa-> maybe i'll have to beat into my mind that 100 Hz kalman filter is fast enough and just use quaternions..
2012-08-03T19:39:01 <+Steffanx> Hehe :)
2012-08-03T19:48:25 < zippe1> I've used SDCC on 8051 quite a bit.
2012-08-03T19:48:29 < zippe1> It's not so bad.

2012-08-04T00:57:09 < sourcebox> That's true
2012-08-04T00:57:15 < zyp> so I just wondered if you were using that or writing your own
2012-08-04T00:57:30 < sourcebox> But there is an demo application from ST
2012-08-04T00:57:43 < sourcebox> In the USB device lib
2012-08-04T01:02:03 < zyp> so, are you wondering about anything specific?
2012-08-04T01:02:28 < zyp> I've looked a bit at DFU, but haven't used it for my own projects yet
2012-08-04T01:03:31 < sourcebox> What I mainly did is the host part, and I'm wondering if someone is interested in such kind of tool
2012-08-04T01:05:05 < zyp> it's a generic DFU loader?
2012-08-04T01:05:10 < sourcebox> Yes
2012-08-04T01:05:17 < zyp> cli or gui? what about OS support?
2012-08-04T01:05:24 < sourcebox> But still work in progress
2012-08-04T01:05:31 < sourcebox> it has a gui
2012-08-04T01:05:48 < sourcebox> should be cross-platform lin/win/osx
2012-08-04T01:06:06 < sourcebox> Screenshot: https://dl.dropbox.com/u/1538141/dfu_tool.png
2012-08-04T01:06:43 < sourcebox> You can select the device to upgrade, a file, then download it
2012-08-04T01:07:21 < zyp> libusb based?
2012-08-04T01:07:24 < sourcebox> Yes
2012-08-04T01:07:42 < zyp> I suspect you would have driver issues on windows
2012-08-04T01:07:53 < sourcebox> It made in Python with Qt, but can be packed as standalone
2012-08-04T01:08:39 < sourcebox> Yes, driver on windows is a problem, but I hope it can be solved
2012-08-04T01:09:13 < sourcebox> As I understand, the generic libusb driver can do it
2012-08-04T01:10:07 < zyp> yes, but you have to load that driver for a specific device before you can access it, so it's not that straight forward
2012-08-04T01:10:54 < sourcebox> That's a good point
2012-08-04T01:11:34 < zyp> anyway, looks like a nice tool
2012-08-04T01:12:04 < zyp> pyside/pyusb is how I make my own stuff too :p
2012-08-04T01:12:08 < sourcebox> I didn't find any gui tool, only command line based stuff
2012-08-04T01:12:53 < sourcebox> I intend to put it on GitHub at some point
2012-08-04T01:13:08 < zyp> I'm a cli guy myself, but I'm sure other people would be interested in your gui
2012-08-04T01:16:21 < sourcebox> I think firmware upgrade for end users is a common task and the DFU protocol is a standard for doing it. Do you think there is a better solution?
2012-08-04T01:22:19 < zyp> not really
2012-08-04T01:23:18 < zyp> though, if the device already have another application to use it over USB, the DFU stuff could be included in it
2012-08-04T01:25:23 < sourcebox> But DFU needs a different mode, so the descriptors have to be changed
2012-08-04T01:25:51 < zyp> yes, that's device side
2012-08-04T01:26:31 < sourcebox> I think the main problem is Windows not recognizing it
2012-08-04T01:26:47 < zyp> that's why I like to ignore windows :p

2012-08-04T01:29:43 < sourcebox> I think udev rules must be defined

2012-08-04T01:32:52 <+Steffann> known
2012-08-04T01:32:53 < R2COM> i remember long long time ago, for PIC, read datasheet, programmed registers, and got my shit working in no time
2012-08-04T01:33:03 < R2COM> here i had to fuck around and fuck around and fuck around
2012-08-04T01:33:18 < zyp> R2COM, just go back to PIC and stop whining then
2012-08-04T01:33:23 < R2COM> SPI was kinda same, but not as bad, it took few days to get that one working too
2012-08-04T01:33:25 <+Steffann> And still you forgot to fuck around?

2012-08-04T01:36:54 < sourcebox> It's good to know that some people with Python knowledge are around here
2012-08-04T01:37:07 < zyp> :)
2012-08-04T01:37:47 < sourcebox> I'm more or less a beginner with it
2012-08-04T01:39:26 <+Steffann> I still have the idea python is more used for hacky and fast written tests than it's used for 'real' things
2012-08-04T01:39:52 < zyp> Steffann, you're pretty wrong about that :p
2012-08-04T01:40:01 <+Steffann> I'm not
2012-08-04T01:40:12 < sourcebox> Google uses a lot of Python code
2012-08-04T01:40:15 < pileopython> I would like to agree with that except that there isnt anything as cross platform and rapid in terms of prottyping
2012-08-04T01:40:48 <+Steffann> Yeah, google is one vs 100000 others using it for hacky projects

2012-08-04T08:00:03 < bcsllc-steve> its an array of chars

2012-08-04T08:01:03 < zippe1> Ok, do you mind having to fix it up all the time?
2012-08-04T08:01:24 < zippe1> if not, the  foo[0] = 0x1a;
2012-08-04T08:01:24 < bcsllc-steve> unsigned char[] = "1A2B3Cblah
2012-08-04T08:01:48 < bcsllc-steve> it a buffer of chars decoded from uart
2012-08-04T08:02:01 < bcsllc-steve> so I pass that pointer into a function
2012-08-04T08:02:03 < zippe1> Ok, so actually it's
2012-08-04T08:02:11 < zippe1> unsigned char foo[32];
2012-08-04T08:02:15 < zippe1> Yes?
2012-08-04T08:02:18 < bcsllc-steve> exactly
2012-08-04T08:02:31 < zippe1> Ok, and you want to make the first character 0x1a?
2012-08-04T08:02:35 < bcsllc-steve> yeap !
2012-08-04T08:02:46 < zippe1> foo[0] = 0x1a;
2012-08-04T08:02:54 < bcsllc-steve> well I need to those first two chars
2012-08-04T08:02:59 < bcsllc-steve> to be a in new var
2012-08-04T08:03:11 < zippe1> Explain more
2012-08-04T08:03:18 < zippe1> What are they? A 16-bit number?
2012-08-04T08:03:29 < bcsllc-steve> 8 bit
2012-08-04T08:03:49 < zippe1> Oh, first two characters are hex digits?
2012-08-04T08:04:00 < bcsllc-steve> 1A in the string - isnt it really 0x31, 0x41 ?
2012-08-04T08:04:12 < bcsllc-steve> but it needs to be converted to 0x1A
2012-08-04T08:04:20 < zippe1> Sorry, your description of what you want completely sucks
2012-08-04T08:04:27 < zippe1> So I'm doing a lot of guessing here
2012-08-04T08:04:27 < bcsllc-steve> im sorry
2012-08-04T08:04:31 < bcsllc-steve> yeah I know
2012-08-04T08:04:48 < bcsllc-steve> they chars in the string as ascii
2012-08-04T08:04:59 < zippe1> I think what you are trying to do is parse the first two characters of your string as hex digits and obtain the 8-bit number they represent
2012-08-04T08:05:12 < bcsllc-steve> exactly my friend
2012-08-04T08:05:20 < zippe1> How fast?
2012-08-04T08:05:38 < bcsllc-steve> im not sure what you mean
2012-08-04T08:05:44 < zippe1> How fast do you need this to be?
2012-08-04T08:05:47 < bcsllc-steve> nothing special
2012-08-04T08:06:04 < zippe1> char tmp[3] = {foo[0], foo[1], 0};
2012-08-04T08:06:05 < bcsllc-steve> its part a big string parsing / importing deal
2012-08-04T08:06:16 < zippe1> int value = strtol(tmp, 0, 16);
2012-08-04T08:06:24 < bcsllc-steve> strol !
2012-08-04T08:07:22 < zippe1> Note that if you are doing *lots* of parsing, there are other, arguably better, options
2012-08-04T08:07:22 < bcsllc-steve> that got my going
2012-08-04T08:07:40 < zippe1> You can play some seriously interesting games with sscanf
2012-08-04T08:08:14 < bcsllc-steve> jthanks
2012-08-04T08:08:15 < bcsllc-steve> thanks
2012-08-04T08:08:33 < bcsllc-steve> is it common to recv data as strings
2012-08-04T08:08:37 < zippe1> Very
2012-08-04T08:08:43 < bcsllc-steve> but its really to be used as hex
2012-08-04T08:09:01 < zippe1> There are lots of ways to encode data
2012-08-04T08:09:17 < zippe1> jpa-:  here has a very nice implementation of the Google protobuf library, for example
2012-08-04T08:09:20 < bcsllc-steve> for example, this is a string I get decoded from an FSK modem: N3000300000005000402000300EE
2012-08-04T08:09:32 < bcsllc-steve> throw the N3 away
2012-08-04T08:09:45 < bcsllc-steve> so now thats all really ascii right ?

2012-08-04T08:10:00 < zippe1> It's all just bytes; it just boils down to how you want to interpret it
2012-08-04T08:11:03 < bcsllc-steve> well for example char foo[] = "1A" is really .... foo[0] = 0x31 , foo[1] = 0x41 right ?
2012-08-04T08:11:17 < zippe1> It's both
2012-08-04T08:11:21 < bcsllc-steve> so its really not 1A
2012-08-04T08:11:31 < zippe1> though, actually, you are forgetting that foo[2] = 0
2012-08-04T08:11:44 < bcsllc-steve> beside thes point
2012-08-04T08:11:57 < zippe1> Not at all
2012-08-04T08:12:02 < zippe1> It's critical, in fact
2012-08-04T08:12:07 < zippe1> That's what "" means
2012-08-04T08:12:11 < bcsllc-steve> ok i know that
2012-08-04T08:12:19 < bcsllc-steve> i know it and i know you know it
2012-08-04T08:12:35 < zippe1> So why are you arguing semiotics. 8)
2012-08-04T08:13:14 < zippe1> Or more to the point; can I help you with something, or should I get back to my own code?
2012-08-04T08:13:33 < bcsllc-steve> sorry to bother  you, thanks for your help sir
2012-08-04T08:13:42 < zippe1> No, seriously…
2012-08-04T08:13:45 < bcsllc-steve> you undid my coders block
2012-08-04T08:13:49 < bcsllc-steve> no i am
2012-08-04T08:13:54 < bcsllc-steve> you answered the question
2012-08-04T08:13:54 < zippe1> Ok, cool.  Enjoy!
2012-08-04T08:33:37 < bcsllc-steve> oh geez

2012-08-04T14:58:57 <+dekar> izua, when did you get ipv6? :)
2012-08-04T14:59:55 <+izua> uh, it's been in beta for a year and a half
2012-08-04T15:00:25 <+izua> this ipv6 day, it became available for all subscribers
2012-08-04T15:00:45 <+izua> they also say something about .ro being the country with the most ipv6 users, etc
2012-08-04T15:00:46 <+dekar> we don't have ipv6 here :/
2012-08-04T15:01:05 <+izua> we also get a /64 block
2012-08-04T15:01:11 <+dekar> nice
2012-08-04T15:01:16 <+izua> that's quite a few internets
2012-08-04T15:01:20 <+dekar> yeah
2012-08-04T15:01:26 < zyp> it's only one subnet
2012-08-04T15:01:41 < zyp> since /64s not are to be subdivided
2012-08-04T15:02:18 <+izua> ah
2012-08-04T15:02:19 < zyp> my isp have started testing ipv6 for opt-in customers
2012-08-04T15:02:35 < zyp> I tried opting in, but it's not rolled out to my area yet
2012-08-04T15:02:37 <+izua> i have no idea about the ipv6 features
2012-08-04T15:02:50 <+dekar> well I guess ipv6 is slower anyway, who'd actually want that? :P
2012-08-04T15:02:56 < zyp> slower?
2012-08-04T15:02:57 <+izua> yeah, it was opt-in too, beta wasn't probably the best wording :P
2012-08-04T15:03:05 <+dekar> more data to transfer
2012-08-04T15:03:08 <+dekar> thus slower
2012-08-04T15:03:12 < zyp> nah
2012-08-04T15:03:17 <+izua> true
2012-08-04T15:03:18 < zyp> not that really matters
2012-08-04T15:03:31 <+dekar> chrome benchmarks ipv6 vs v4 every time you load a page
2012-08-04T15:03:33 <+izua> but not that much i think
2012-08-04T15:03:44 < zyp> IIRC the ipv6 header is smaller than the ipv4 header, due to making some fields optional
2012-08-04T15:03:44 <+dekar> ipv6 gets a 150ms bonus so it wins most of the time
2012-08-04T15:04:06 <+izua> i don't think that matters in small stuff, like web pages, you should probably try downloading big stuff :P
2012-08-04T15:04:18 < zyp> doesn't matter in downloads either
2012-08-04T15:04:22 <+izua> that's where I see the overhead of ipv6 adding
2012-08-04T15:04:32 <+izua> i don't know, i might care.
2012-08-04T15:04:36 <+izua> i like my download speed
2012-08-04T15:05:11 <+izua> on the local track^W linux user group tracker, i get ~9.8-10.2MBps with 3-4 seeders
2012-08-04T15:05:27 < zyp> large transfers operate with large packets
2012-08-04T15:05:28 <+izua> which is close to the line limit methinks
2012-08-04T15:05:47 <+izua> only if the ISP has jumbo frames enabled. and they don't
2012-08-04T15:06:06 <+dekar> yeah it only matters for small stuff
2012-08-04T15:06:30 <+dekar> if you download a few hundred bytes then it hurts most
2012-08-04T15:07:08 <+dekar> izua, well common frame sizes are >1400, that's quite low overhead already
2012-08-04T15:07:24 <+dekar> the ipv6 header is probably <50 bytes
2012-08-04T15:07:42 <+izua> dunno, but it's big
2012-08-04T15:07:54 <+izua> 16 bytes, twice, that's 32 just for addressing
2012-08-04T15:07:59 <+dekar> yeah
2012-08-04T15:09:29 <+izua> i wonder if there's any embedded ipv6 lib
2012-08-04T15:09:52 <+dekar> btw, lua performance is pretty good on the stm32 imo
2012-08-04T15:10:00 < zyp> ipv6 header is 40 bytes
2012-08-04T15:10:00 <+dekar> even though I have it use double
2012-08-04T15:10:04 <+izua> or i could make the router reply to the whole /64 block
2012-08-04T15:10:21 <+izua> for the moment, i have to learn how to read ipv6 addresses :)
2012-08-04T15:10:50 <+dekar> the ipv6 compression stuff is weird
2012-08-04T15:10:58 < zyp> the addr format?
2012-08-04T15:11:00 <+dekar> leaving out the zeroes
2012-08-04T15:11:02 <+dekar> yeah
2012-08-04T15:11:04 < zyp> it's pretty easy
2012-08-04T15:11:10 <+dekar> I don't like it
2012-08-04T15:11:36 <+dekar> I know it's easy, I don't like variable length
2012-08-04T15:11:44 < zyp> think about it like this: first part of the addr identifies the network, last part identifies the host
2012-08-04T15:12:01 < zyp> depending on the network or host, those parts may have different lengths
2012-08-04T15:12:18 < zyp> so you start in either end, extending towards the middle
2012-08-04T15:12:19 <+dekar> I meant something else, you can have two colons in the address
2012-08-04T15:12:25 < zyp> yes
2012-08-04T15:12:42 < zyp> so you leave the middle sections as zeros, and then strip that part out
2012-08-04T15:12:55 < zyp> so the part before the double colon is the network part, the part after is the host part
2012-08-04T15:12:59 <+dekar> it doesn't have to be in the middle afaik
2012-08-04T15:13:17 < zyp> no, but in practice it usually is
2012-08-04T15:13:24 < zyp> because of the host/network seperation
2012-08-04T15:13:27 <+dekar> you can have like ::1
2012-08-04T15:13:36 <+dekar> ::1 is a valid ipv6 address
2012-08-04T15:13:43 < zyp> yes, it's localhost
2012-08-04T15:13:49 <+dekar> looks pretty ugly to me
2012-08-04T15:13:59 < zyp> it's equivalent to 0::1, which reads as «network 0, host 1»
2012-08-04T15:14:13 <+dekar> which is equivalent to 00:00::1
2012-08-04T15:14:24 < zyp> and to me it looks much more sensible than 127.0.0.1
2012-08-04T15:14:37 < zyp> which is network 127, host 1, or something like that
2012-08-04T15:15:47 < zyp> one reason for the huge address space is that you can reserve the first 64 bits to identify network, and have the last 64 always identify the host on the network
2012-08-04T15:16:33 <+dekar> anyway concerning lua, I wrote some script toggling a pin 1000 times and running it on my PC doing the toggle via USB takes like 2 seconds, running it on the stm32 is a fraction of a second
2012-08-04T15:16:56 <+dekar> so I can recommend it for scripting, works well and is incredibly easy to port

2012-08-04T15:18:56 <+dekar> zyp, I actually have used ipv6 before, my server has a bunch of those things
2012-08-04T15:19:21 <+dekar> and overall I am fine with it, I just don't like the "compression"
2012-08-04T15:19:42 <+dekar> oh and the net split it comes with
2012-08-04T15:22:35 <+dekar> http://pastebin.com/JEdfbwkd
2012-08-04T15:23:08 <+dekar> dlmalloc is pretty cool, you can get all those fancy stats from it
2012-08-04T15:24:07 <+dekar> that was transferring a 2kb lua application via usb and compiling plus executing it on the stm32
2012-08-04T15:25:08 <+Steffanx> 17.9521484375 kB .. lol?
2012-08-04T15:25:24 < zyp> :D
2012-08-04T15:26:06 <+dekar> Steffanx, as you might know lua usually uses float/double
2012-08-04T15:26:34 <+Steffanx> it's still ugly
2012-08-04T15:26:43 < zyp> so you have 0.1484375 bytes
2012-08-04T15:27:08 <+dekar> zyp, and I intend on keeping them
2012-08-04T15:27:14 <+dekar> :)
2012-08-04T15:27:47 <+Steffanx> Yeah, you can't throw away memory
2012-08-04T15:27:52 <+Steffanx> corruption etc.
2012-08-04T15:28:04 <+dekar> that's 1.1875 bits
2012-08-04T15:28:12 <+dekar> not too shabby

2012-08-04T21:49:15 < R2COM> so it looks like sam4s is a competitor for stm32f4...
2012-08-04T21:56:13 < cjbaird> They have an 'Xplaned' board with 8MB SRAM, too. Much like the AVR32-xplained board I bought recently. Hmm.
2012-08-04T21:57:07 < cjbaird> 8Mbit, rather. 1MB.

2012-08-04T22:25:15 < zippe1> R2COM: except that sam4s is kinda slow and boring
2012-08-04T22:25:38 < zippe1> R2COM: If you want a serious competitor to STM32F4 you are looking at LPC43xx
2012-08-04T22:26:10 < zippe1> R2COM: or maybe some of the Kinetis parts, though they are also slow.
2012-08-04T22:28:07 < zippe1> R2COM: sam4s also vaporware last time I looked
2012-08-04T22:29:01 < zippe1> The SAM4SA and SAM4SD parts will be more interesting when they finally arrive
2012-08-04T23:14:19 < R2COM> hmm

2012-08-04T23:14:49 < R2COM> its NXP right
2012-08-04T23:14:51 < R2COM> ?\
2012-08-04T23:14:52 < R2COM> ok
2012-08-04T23:15:02 < R2COM> but i looked at their website, i didnt find tool support?
2012-08-04T23:15:18 < R2COM> one supposed to use Keil/MDK/Iar whatever? or what?
2012-08-04T23:16:09 < R2COM> and well yes, sam4s is 120MHz, and stm32f4 is 168MHz. well..
2012-08-04T23:17:10 < R2COM> but if sam4s has less bugs in it, and free good development support, then its not that bad, if you can make your stuff work
2012-08-04T23:17:43 < R2COM> I'm now playing with stm32f4 anyhow, will see maybe i do some test board for sam4s and play, see how that one is
2012-08-04T23:22:37 < zippe1> You can use anything that supports the M3
2012-08-04T23:22:40 < zippe1> Code Red, for example
2012-08-04T23:22:55 < zippe1> R2COM: Do you have a source for sam4s parts?
2012-08-04T23:23:20 < R2COM> what you mean source?
2012-08-04T23:23:25 < R2COM> no they are not available yet
2012-08-04T23:23:47 < R2COM> also, take in account that Atmel Studio 6 is free
2012-08-04T23:24:00 < R2COM> but
2012-08-04T23:24:02 < zippe1> Yet another dodgy wrapper around gcc
2012-08-04T23:24:29 < R2COM> sam3s, and sam4s are pin compatible, so its possible to do some board even for lower grade, and just see how it is, and later on put sam4s
2012-08-04T23:26:50 < cjbaird> At least it's a somewhat recent GCC... Microchip throw you a GCC-3.x compiler in their graciousness.
2012-08-04T23:29:20 < zippe1> cjbaird: uh, no
2012-08-04T23:29:21 < zippe1> gcc version 4.5.1 MPLAB XC32 v1.00 (Microchip Technology)
2012-08-04T23:29:44 < zippe1> I won't pretend 4.5.1 is cutting-edge anything, but at least check your rumours
2012-08-04T23:30:05 < zippe1> Many folks playing with pic32 are using the pinguino bits
2012-08-04T23:30:08 <+Steffanx> Cutting-edge never means better I case of GCC :P
2012-08-04T23:30:15 <+Steffanx> *in
2012-08-04T23:31:33 < cjbaird> It was ~3 months ago I was looking at the PIC32 stuff, and I thought that was GCC-3 being thrown at people (with the licence daemon crap & etc.)  GCC-4.x, being GPL3, denies them that.
2012-08-04T23:36:33 < zippe1> The Mplab-X betas have always been 4.x, and they've been running for over a year now
2012-08-04T23:36:59 < zippe1> I don't know what you were looking at, but it had nothing to do with anything current.  There is no license manager, it's all free.
2012-08-04T23:37:58 < R2COM> and the code red by the way, you mentioned costs 500$
2012-08-04T23:38:13 < R2COM> which is ok if one wants to go with that stuff for some time
2012-08-04T23:38:16 < zippe1> Yes.  You wanted a canned set of dev tools, someone has to pay for it
2012-08-04T23:38:29 < R2COM> as i said, atmel studio 6 is free
2012-08-04T23:38:31 < zippe1> You can build for lpc43xx with any of the open-source toolchains
2012-08-04T23:38:46 < zippe1> R2COM: you pay for AS6 with every chip you buy from Atmel
2012-08-04T23:39:01 < R2COM> i know i can, right now for example I'm using: Eclipse + Gnu ARm compiler + Atollic GDB server, on win7
2012-08-04T23:39:16 < zippe1> Ok, so I don't understand what you're complaining about
2012-08-04T23:39:34 < zippe1> Tools for lpc43xx ~= tools for STM32F4
2012-08-04T23:39:36 < R2COM> I'm not, I'm just trying to see what is there in a same class as f4
2012-08-04T23:39:57 < zippe1> And I'm telling you that Kinetis and lpc43xx are about it
2012-08-04T23:40:06 < zippe1> They both actually exist
2012-08-04T23:40:14 < zippe1> The lm4s exists, but they're even slower
2012-08-04T23:40:37 < zippe1> If you like the LMI parts (I do, mostly) then they're worth a look
2012-08-04T23:41:18 < zippe1> But I wouldn't put much stock in sam4s until you can actually buy one; my bunions say late 2q13 at the earliest.
2012-08-04T23:41:49 < R2COM> hm, so they not going to be out quite soon?
2012-08-04T23:42:07 < R2COM> well..
2012-08-04T23:42:37 < zippe1> I don't know.  Sign an NDA with Atmel and they might share their schedule with you
2012-08-04T23:42:59 < zippe1> Their track record is all I have to go on
2012-08-04T23:44:16 < zippe1> Looking at the sam4s page-o-rectangles, I find it seriously short on peripherals
2012-08-04T23:44:31 < R2COM> also they have those ARM9 now, with 400MHz, but thats not in f4 class range i guess, also that one doesnt have FPU
2012-08-04T23:45:07 < zippe1> Only 4 UARTs, only 1 SPI, only 5 timers, no DMA
2012-08-04T23:45:33 < zippe1> Hmm, I take that back
2012-08-04T23:45:38 < zippe1> They have distributed peripheral DMA
2012-08-04T23:52:39 < R2COM> and for hardware, SAM-ICE, 100$ can do most of those SAMs.  i see they have more expencive ones, but this one works

2012-08-04T23:55:17 < zippe1> cjbaird: I think you are still confused.  You are looking at the documentation for the wrong toolchain.
2012-08-04T23:55:22 < zippe1> You want mplab-x
2012-08-04T23:57:22 < cjbaird> No, that's the toolchain I was investigating a few months ago. I didn't discover about the one you've mentioned.

2012-08-05T00:03:58 < cjbaird> Even funnier is the example below Microchip's: http://www.makeuseof.com/tag/10-ridiculous-eula-clauses-agreed/
2012-08-05T00:04:11 < zippe1> Someone is a bit confused about what free software is all about.  Oh well.
2012-08-05T00:05:53 < cjbaird> A bit. He's involved with my long-time arch nemesis Dontronics..
2012-08-05T00:06:24 < zippe1> Don'tronics?
2012-08-05T00:07:18 < zippe1> Amusingly, they are also resellers of the Unnamed Company's products
2012-08-05T00:07:19 < cjbaird> An Australian electronics garage business. Also the country's first 'Green Card Lawyer'-style Internet spammer.
2012-08-05T00:08:52 < cjbaird> He still hasn't paid up for the $14 in extra long-distance phone charges that his spam cost me... :P
2012-08-05T00:09:04 < qyx_> "As far as I can see it does not even require that the original author be acknowledged"
2012-08-05T00:09:07 < qyx_> what?
2012-08-05T00:10:12 < cjbaird> The BSD licences have that clause about acknowledgement.. not that anyone ever fulfills it.
2012-08-05T00:10:40 < zippe1> cjbaird: you'd be surprised.  My Mini came with a book full of nothing but opensource license text and attributions
2012-08-05T00:11:09 < zippe1> Borrow someone's iPhone and look in the About section, there's an enormous scrolling list of the same
2012-08-05T00:11:10 < cjbaird> Apple being a exception :)
2012-08-05T00:11:34 < zippe1> I wish Apple built the Mini.
2012-08-05T00:11:53 < zippe1> Getting into it would be hard, but it wouldn't squeak or rattle...
2012-08-05T00:12:52 < cjbaird> A friend's old Mini CooperS reminds me more of the grotty CP/M systems..
2012-08-05T00:14:58 < zippe1> I am having S-100 flashbacks

2012-08-05T08:55:30 < dongs> i do have telemetry downlink so I can tell how high.
2012-08-05T08:55:32 < bcsllc-steve> could you even see it from the ground

2012-08-05T09:32:21 < zippe1> Man, I really need to remove the remap at zero
2012-08-05T09:32:44 < bcsllc-steve> is there video of its flight ?
2012-08-05T10:18:36 < dongs> man this chiense ublox GPS is garabge
2012-08-05T10:18:46 < dongs> my mtk shit has been getting a lock wiht liek 5 sats sitting on my window
2012-08-05T10:18:52 < dongs> this shit had liek 12 sats and never got any lock
2012-08-05T10:21:44 <+izua_> it needs to view the ones in the southern hemisphere too
2012-08-05T10:22:26 <+izua_> what if you're in australia and facing your gps down, seeing the northern sky through the earth core, and hiding the southern one?
2012-08-05T10:23:34 < dongs> you missed the part where the cheap trash gps gets a lock
2012-08-05T10:24:12 <+izua_> it will get one
2012-08-05T10:24:19 <+izua_> just wait for all 24 sattelites to become visible
2012-08-05T10:24:52 < bcsllc-steve> what is gps ?
2012-08-05T10:25:04  * bcsllc-steve googles
2012-08-05T10:25:09 < bcsllc-steve> im just kidding
2012-08-05T10:26:07 < dongs> gay positioning system. homo locator.
2012-08-05T10:27:01 < bcsllc-steve> thats the kind you use ?
2012-08-05T10:27:22 < bcsllc-steve> im sorry im joking
2012-08-05T10:27:32 < bcsllc-steve> im in a playful kiddish mood tongith
2012-08-05T10:30:55 < jpa-> dongs: did you wait 15 minutes for it to download the ephemeris etc?
2012-08-05T10:31:23 < jpa-> first start of gps always takes ages :)

2012-08-05T10:33:28 < bcsllc-steve> why is a function prototype called a prototype ?
2012-08-05T10:33:43 < bcsllc-steve> in C ofc
2012-08-05T10:34:41 < jpa-> "prototype: An original object or form which is a basis for other objects, forms, or for its models and generalizations"   makes sense to me
2012-08-05T10:35:07 < jpa-> you have prototypes in stdio.h, for example, and don't care what specific implementation is behind it
2012-08-05T10:35:55 < bcsllc-steve> hmm ok
2012-08-05T10:36:00 < bcsllc-steve> thanks
2012-08-05T10:38:43 < bcsllc-steve> i always understood prototype as a "beta" version
2012-08-05T10:38:49 < bcsllc-steve> or a physical product
2012-08-05T10:39:13 < bcsllc-steve> "This is just a prototype, the final version will have feature xyz"
2012-08-05T10:39:44 < bcsllc-steve> actually that describes your quote

2012-08-05T11:16:36 < bcsllc-steve> does freee work with pointer to a char array ?
2012-08-05T11:16:47 < bcsllc-steve> or do I have to create the ptr with malloc
2012-08-05T11:16:54 < bcsllc-steve> free()
2012-08-05T11:17:18 < bcsllc-steve> another words, if I create the ptr by doing: unsigned char[50];
2012-08-05T11:17:45 < bcsllc-steve> oops I mean unsigned char buffer[50];
2012-08-05T11:17:55 < bcsllc-steve> unsigned char * ptr = &buffer[0];
2012-08-05T11:17:59 < bcsllc-steve> free(ptr)
2012-08-05T11:30:58 < dongs> freeing statically allocated things usually leads to bad things.
2012-08-05T11:31:35 < bcsllc-steve> ok

2012-08-06T20:35:09 < carp3> Hi, is there any reference design for minimal stm32 board?

2012-08-06T20:45:34 <+dekar_> what's minimal? I think you only have to power it up and set the BOOT0 and BOOT1 pins
2012-08-06T20:47:27 < carp3> Debugger ...  recommended supply circuit. ... etc...
2012-08-06T20:47:59 < carp3> i found it. never mind. http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00164185.pdf
2012-08-06T20:48:52 < pileopython> carp3: https://github.com/soycamo/maplebacon is pretty good for usb
2012-08-06T20:49:35 < pileopython> you could get rid of the seperate analog supply
2012-08-06T20:50:29 < pileopython> or if you went with no usb you can get rid uf the 3 parts which are usb
2012-08-06T20:52:27 < carp3> STF202 is necessary? pileopython

2012-08-06T21:03:05 < zyp> carp3, minimal depends on which chip you choose
2012-08-06T21:04:10 < carp3> STM32F103CBT6   with ADC + USB    ,zyp
2012-08-06T21:05:23 < zyp> decoupling caps, external crystal, maybe seperate avcc rail if you care a lot about adc performance

2012-08-06T21:06:21 < zyp> internal RC oscillator is not stable enough for USB, so external crystal is required
2012-08-06T21:06:32 < carp3> as i want to use it in a car.   i'm worried about noises.  that's why i'm looking for a reference design

2012-08-06T21:19:00 < pileopython> carp3 its actually a lot simpler than the minimal 22-33 ohm resistors for usb and if you compare the circuit above to the maple mini you will get the idea

2012-08-06T21:24:28 < zyp> wouldn't say a lot simpler
2012-08-06T21:24:50 < zyp> it's six pads, equivalent resistors would be six pads as well
2012-08-06T21:25:41 < zyp> of course, no ESD protection in the latter case

2012-08-06T21:31:52 < pileopython> which is what we like about it.
2012-08-06T21:32:40 < pileopython> two parts vs the two parts i use for most of my other usb designs and we get ESD and the ability to disconect from the bus
2012-08-06T21:32:43 < pileopython> win win
2012-08-06T21:33:46 < pileopython> so zyp: i would.
2012-08-06T21:34:28 < pileopython> simple sometimes means peace of mind.

2012-08-06T21:43:27 < zyp> ability to disconnect has nothing to do with the stf202, it's done by the external transistor
2012-08-06T21:57:07 < pileopython> yeah through the 202
2012-08-06T21:58:19 < pileopython> I was talking about the combination (hence 2 parts)
2012-08-06T21:59:44 < pileopython> sorry  I thought that was clear (the transistor and the 202 v the minimal resistors in line with D- and D+)
2012-08-06T22:00:02 < zyp> you would achieve the same with three resistors instead of the 202, that's why I said six pads
2012-08-06T22:00:27 < pileopython> this is silly
2012-08-06T22:01:08 < pileopython> I though the 202 was a lot of doing it right for not a lot of parts
2012-08-06T22:01:13 < pileopython> bleah
2012-08-06T22:02:06 < zyp> sure, I'd probably use it if I were doing usb on F1
2012-08-06T22:02:51 < zyp> but it wouldn't be much simpler :p
2012-08-06T22:03:04 < pileopython> carp3: anyways I thk thats a pretty good baseline for a minimal usb stm design.
2012-08-06T22:03:30 < zyp> agreed

2012-08-07T06:05:37 < bcsllc-steve> hey guys I need some help Im willing to pay for
2012-08-07T06:06:02 < bcsllc-steve>  i have an "action time" in hours:mins:sec:frames
2012-08-07T06:06:13 < bcsllc-steve> each in a seperate var
2012-08-07T06:06:21 < bcsllc-steve> there is 30 frames to  a second
2012-08-07T06:06:28 < bcsllc-steve> now I also have a var containg a "pre-fire"
2012-08-07T06:06:35 < bcsllc-steve> its in tenths of a second
2012-08-07T06:06:42 < bcsllc-steve> from 0 - 99
2012-08-07T06:06:54 < bcsllc-steve> so 99 is 9.9 seconds
2012-08-07T06:07:13 < bcsllc-steve> then I have a current time whic is the same as before hours:mins:sec:frames
2012-08-07T06:07:43 < bcsllc-steve> example event time is 01:01:01:01
2012-08-07T06:08:00 < bcsllc-steve> i need to subtract the 9.9 seconds from the event time
2012-08-07T06:08:09 < bcsllc-steve> and be able roll each variable back as needed
2012-08-07T06:08:15 < dongs> i did exactly this like 5 years ago
2012-08-07T06:08:23 < bcsllc-steve> cool
2012-08-07T06:08:36 < dongs> shifting subtitle timing or someshit
2012-08-07T06:08:51 < dongs> which was also hms:frame or something
2012-08-07T06:08:54 < bcsllc-steve> so where do I start ?
2012-08-07T06:09:09 < bcsllc-steve> 99  / 10 ? 99 * 1000
2012-08-07T06:09:24 < bcsllc-steve> i think i need convert hour to frames
2012-08-07T06:09:28 < bcsllc-steve> * 108000
2012-08-07T06:09:28 < bcsllc-steve> ?
2012-08-07T06:09:29 < dongs> is it actualyl 30 frames or
2012-08-07T06:09:33 < bcsllc-steve> yes
2012-08-07T06:09:36 < dongs> 29.97 or etc
2012-08-07T06:09:42 < bcsllc-steve> lets just say 30
2012-08-07T06:09:45 < dongs> or smpte drop or nondrop or blah
2012-08-07T06:10:01 < dongs> there's so much shit that can be variable for "frames" unless you know the exact info
2012-08-07T06:10:05 < bcsllc-steve> yeah skip that stuff
2012-08-07T06:10:29 < bcsllc-steve> frames = 0 thur 229
2012-08-07T06:10:29 < bcsllc-steve> 29
2012-08-07T06:10:42 < dongs> so 1 second = 29 frames
2012-08-07T06:10:48 < bcsllc-steve> 30 frames
2012-08-07T06:10:56 < bcsllc-steve> 0 - 29
2012-08-07T06:11:04 < dongs> (or whatever). so 9.9 = 30*9.9
2012-08-07T06:11:25 < dongs> convert .9 into frames
2012-08-07T06:11:27 < dongs> and subtract seconds separately
2012-08-07T06:12:06 < bcsllc-steve> ok so 9.9 seconds is 297 frames
2012-08-07T06:12:45 < dongs> so 0.9 = 27 frames
2012-08-07T06:12:48 < bcsllc-steve> right
2012-08-07T06:12:52 < dongs> subtract that from frames #
2012-08-07T06:12:58 < dongs> then do the rest of time math as normal time
2012-08-07T06:13:06 < dongs> i.e. just -9 seconds from the timestamp.
2012-08-07T06:13:14 < dongs> you can either convert h:m:s into seconds
2012-08-07T06:13:16 < dongs> subtract
2012-08-07T06:13:18 < dongs> adn go back to hms
2012-08-07T06:13:34 < dongs> or do some math directly on hms shit
2012-08-07T06:14:05 < bcsllc-steve> do I want 9 seconds * 30 first ?
2012-08-07T06:14:08 < bcsllc-steve> 270
2012-08-07T06:14:17 < dongs> no that was jsut example of how many frames y ou're shifting by
2012-08-07T06:16:21 < bcsllc-steve> ok so I need to start with subtracting 27 frames from 01:01:01:01 ?
2012-08-07T06:16:29 < dongs> yes
2012-08-07T06:16:36 < bcsllc-steve> 01 -27 = -26
2012-08-07T06:16:51 < dongs> yes, abs() that.
2012-08-07T06:16:58 < bcsllc-steve> 26
2012-08-07T06:17:31 < bcsllc-steve> now the seconds
2012-08-07T06:17:40 < bcsllc-steve> do 9.9 or 9 ?
2012-08-07T06:17:45 < dongs> 9.
2012-08-07T06:17:49 < bcsllc-steve> 9 * 30
2012-08-07T06:17:51 < dongs> just the integer part.
2012-08-07T06:17:56 < bcsllc-steve> 270
2012-08-07T06:18:21 < bcsllc-steve> oops, no I subtract 9 from the seconds
2012-08-07T06:18:23 < bcsllc-steve> 01 - 9
2012-08-07T06:18:39 < bcsllc-steve> ?

2012-08-07T14:32:24 < Laurenceb> im wondering how flexible lipo is
2012-08-07T14:32:36 < Laurenceb> contemplating trying with a G clamp
2012-08-07T14:33:31 < zyp> isn't a lipo cell rolled up film?
2012-08-07T14:33:54 < Laurenceb> yeah
2012-08-07T14:34:06 < Laurenceb> i need to bend one slightly for an enclosure
2012-08-07T14:34:14 < Oldboy> bad idea in my opinion
2012-08-07T14:34:17 < zyp> anyway, if you try bending the cell, you'll end up shorting the layers
2012-08-07T14:34:22 < zyp> and then you get to watch fireworks
2012-08-07T14:34:26 < Laurenceb> as in middle up by a few mm
2012-08-07T14:34:29 < Laurenceb> over 50mm
2012-08-07T14:34:59 < Thorn> btw, has anyone heard anything specific about that "faster FFT" algorithm?
2012-08-07T14:35:17 < zyp> which?
2012-08-07T14:35:32 < Laurenceb> fft faster than fft?
2012-08-07T14:36:07 < Thorn> it's been reported a few weeks ago. some variation on fft
2012-08-07T14:37:13 < zyp> http://science.slashdot.org/story/12/01/20/037236/faster-than-fast-fourier-transform <- this?
2012-08-07T14:37:44 < Thorn> probably
2012-08-07T14:37:52 < Laurenceb> oh
2012-08-07T14:37:58 < Laurenceb> isnt that an approximation?
2012-08-07T14:38:03 < Thorn> but I've read about it much later than January
2012-08-07T14:40:54 < Thorn> I wonder if it can be successfully hardware accelerated using existing MAC blocks etc.

2012-08-07T15:57:54 < Tectu> izua_, seriously?
2012-08-07T15:58:35 < zyp> Tectu, a segfault nowadays is just a «trying to access unmapped page» fault
2012-08-07T15:58:57 < Tectu> zyp, do ARMs have vmm? o0
2012-08-07T15:59:00 < Tectu> virtual memory...
2012-08-07T15:59:15 < Thorn> CPUs do
2012-08-07T15:59:16 < zyp> no, cortex-m doesn't
2012-08-07T15:59:27 < Thorn> MCUs can have memory protection
2012-08-07T15:59:39 < zyp> but you'll still get a busfault if you try accessing memory areas that doesn't exist
2012-08-07T15:59:56 < Tectu> zyp, i see
2012-08-07T16:00:06 < zyp> and with the MPU capable ones, you'll also get a fault if you try accessing areas protected by the MPU
2012-08-07T16:00:12 < Tectu> and can they really divide by zero without crashing?
2012-08-07T16:00:16 < zyp> provided that you use the MPU of course
2012-08-07T16:00:49 < Thorn> do realtime systems ever use vitual memory btw? it looks like a huge source of nondetermisism
2012-08-07T16:00:55 < Tectu> zyp,  ^
2012-08-07T16:01:03 < zyp> how to handle a zero division is really up to you
2012-08-07T16:01:48 < zyp> I haven't checked the specifics on cortex-m, but I suspect you may get a fault for that too, and handle it as you want
2012-08-07T16:01:55 < zyp> fault != crash
2012-08-07T16:02:12 < Tectu> so i get a fault which can be handled like "turn divided by zero LED on" and continue? :D
2012-08-07T16:02:36 < zyp> yes
2012-08-07T16:02:55 < zyp> a fault is just an interrupt
2012-08-07T16:03:19 < zyp> though, directly returning from it will return to the faulting division
2012-08-07T16:04:11 < Thorn> >You can set up the DIVBYZERO bit in the NVIC Configuration Control Register so that when a
2012-08-07T16:04:11 < Thorn> divide by zero occurs, a fault exception (usage fault) takes place. Otherwise, <Rd> will become 0 if a
2012-08-07T16:04:11 < Thorn> divide by zero takes place.
2012-08-07T16:04:19 < zyp> but you can modify the return addr to skip it, do some unwinding stuff to handle it, or just kill off that thread and switch to another
2012-08-07T16:04:26 < Thorn> ^^ The Book page 73
2012-08-07T16:04:32 < zyp> right, that's what I suspected
2012-08-07T16:04:55 < zyp> so you can actually configure whether a zero-division will trigger a fault or silently be ignored

2012-08-07T22:52:17 < Laurenceb_> qt is complex
2012-08-07T22:52:30 < Laurenceb_> i just want a simple graph viewer
2012-08-07T22:52:58 < Laurenceb_> how the hell do i create a paintevent?
2012-08-07T22:53:53 <+Steffanx> Go for drag and drop VS 2010 something :P.net
2012-08-07T22:56:06 < Laurenceb_> haha
2012-08-07T22:56:18 < Laurenceb_> i guess i spawn something that runs in a loow
2012-08-07T22:56:21 < Laurenceb_> *loop
2012-08-07T22:56:25 < zyp> I used a QGLWidget and just passed the graph data to opengl to draw
2012-08-07T22:56:41 < Laurenceb_> i have data coming in from /dev/usbACM0 or something
2012-08-07T22:56:47 < Laurenceb_> and want to plot it
2012-08-07T22:56:56 < Laurenceb_> i guess i could haxor gnuplot
2012-08-07T22:56:58 < Laurenceb_> lulz
2012-08-07T22:57:27 < zyp> http://paste.jvnv.net/view/aIkOH <- here is the code drawing this: http://bin.jvnv.net/f/GHc37.png
2012-08-07T22:57:33 < Laurenceb_> but it tends to end badly when you try to replot at 10hz
2012-08-07T22:57:35 < Laurenceb_> thanks
2012-08-07T22:58:13 <+Steffanx> with python .. ofcourse :P
2012-08-07T22:58:20 < Laurenceb_> lulwut
2012-08-07T22:58:24 <+Steffanx> You proved my point again zyp :P
2012-08-07T22:58:35 < zyp> which point? :p
2012-08-07T22:58:38 < Laurenceb_> opengl using qt using python
2012-08-07T22:58:41 <+Steffanx> python => hacky test language :P
2012-08-07T22:58:55 < zyp> nah, it's fine
2012-08-07T22:59:17 < zyp> I'm going to make the widget reusable and integrate it into the final application
2012-08-07T23:00:51 < Laurenceb_> hmm think ill make a qt gui
2012-08-07T23:01:03 < Laurenceb_> i want something professional that i can ship to windoze users
2012-08-07T23:01:56 < zyp> I used opengl because I wanted something fast, drawing graphs point by point is slow
2012-08-07T23:08:57 < Laurenceb_> so how do i do this?
2012-08-07T23:09:11 < Laurenceb_> is there a way to test for data from /dev/ttyACM0?
2012-08-07T23:09:21 < Laurenceb_> or do i have a thread thats polling it
2012-08-07T23:15:54 < zyp> since it's a tty, I'd use pyserial in python
2012-08-07T23:16:10 < Laurenceb_> heh
2012-08-07T23:16:24 < Laurenceb_> wait actually its usbACM0
2012-08-07T23:16:35 < zyp> still a tty
2012-08-07T23:17:48 < Laurenceb_> i see
2012-08-07T23:18:10 < Laurenceb_> can you compile python to an exe for windows?
2012-08-07T23:18:17 < Laurenceb_> that doesnt have dependancies?
2012-08-07T23:19:08 < zyp> http://www.py2exe.org/
2012-08-07T23:19:14 < zyp> never used it though
2012-08-07T23:19:48 < Laurenceb_> thanks
2012-08-07T23:20:13 < Laurenceb_> ive got some graph code already using pyserial and wxwindows
2012-08-07T23:23:25 < Laurenceb_> i used a separate thread then the queue thingy
2012-08-07T23:23:33 < Laurenceb_> to pass data to the window

2012-08-08T00:23:06 < Laurenceb_> its actually possible using octave
2012-08-08T00:23:19 < Laurenceb_> but thats not entirely professional
2012-08-08T00:46:44 <+izua> you can just use bray's terminal
2012-08-08T00:46:53 <+izua> it can parse quite a bit of data formats and graph it

2012-08-08T01:08:01 < Laurenceb_> hmm whats mono like these days?
2012-08-08T01:08:28 < karlp> pretty decent,
2012-08-08T01:08:33 < karlp> most stuff works.
2012-08-08T01:08:41 < karlp> just a big dependency that's all
2012-08-08T01:09:20 <+Steffanx> And it's (much) slower
2012-08-08T01:09:24 < zyp> doesn't mono just support a pretty old API version or something like that?
2012-08-08T01:09:25 < Laurenceb_> yeah
2012-08-08T01:09:37 < Laurenceb_> maybe i should try c#
2012-08-08T01:09:46 < Laurenceb_> ive never really written any serious gui
2012-08-08T01:09:48 < zyp> I don't have any experience with it myself, but I overheard it in an discussion between some friends
2012-08-08T01:09:58 <+Steffanx> It's pretty up to date nowadays
2012-08-08T01:10:09 <+Steffanx> most of .net 4.0
2012-08-08T01:10:11 <+Steffanx> or even 4.5
2012-08-08T01:10:30 < cjbaird> Anything cool to buy today? I'm making another order with E14..
2012-08-08T01:10:41 < Laurenceb_> *cough* raspberry pi
2012-08-08T01:10:45 < zyp> really? because what I heard was the exact opposite

2012-08-08T01:11:00 < karlp> can someone buy some mrf24j40ma modules for me?
2012-08-08T01:11:00 <+Steffanx> Something are just completely missing
2012-08-08T01:11:05 < cjbaird> Laurenceb_: already got 5 of them..
2012-08-08T01:11:06 < karlp> mine keep getting stuck in customs.
2012-08-08T01:11:19 <+Steffanx> *some things
2012-08-08T01:11:51 < zyp> right
2012-08-08T01:12:23 < zyp> they were talking about porting some application to mono, maybe they were talking about missing support for a specific part then
2012-08-08T01:13:03 < Laurenceb_> C# supported fine then
2012-08-08T01:13:31 <+Steffanx> Just use monodevelop and you'll see (it use GTK though)
2012-08-08T01:13:46 <+Steffanx> So no winforms :)
2012-08-08T01:14:20 <+Steffanx> There are Qt bindings as well

2012-08-08T01:42:21 < sourcebox> karlp: I have a question regarding the st-util. Is it possible that the GDB memory map is missing an entry for the EEPROM?
2012-08-08T01:42:57 < karlp> given that only the L series has eeprom, yeah,
2012-08-08T01:43:04 < karlp> I think there's even a comment in the source about it.
2012-08-08T01:43:11 < sourcebox> Ok
2012-08-08T01:43:20 < karlp> also, I don't know how gdb / linker scripts use the eeprom
2012-08-08T01:43:26 < karlp> so it wasn't a priority at the time.
2012-08-08T01:43:39 < sourcebox> I was a little bit confused cause the addresses can't be shown
2012-08-08T01:43:46 < karlp> hmm,
2012-08-08T01:44:00 < karlp> what, with just printing addresses?
2012-08-08T01:44:04 < karlp> I thought it would try and print anywhere.
2012-08-08T01:44:15 < karlp> but does the eeprom just let itself be read as if it was normal memory?
2012-08-08T01:44:19 < sourcebox> you can't access them
2012-08-08T01:44:51 < zyp> try: set mem inaccessible-by-default off
2012-08-08T01:45:40 < sourcebox> ok, that seems to do something
2012-08-08T01:46:13 < zyp> are you able to read eeprom now?
2012-08-08T01:46:30 < sourcebox> thank you, that looks good
2012-08-08T01:47:02 < sourcebox> I have to include it in the gdb scripts...

2012-08-08T05:17:51 < karlp> so bed instead.
2012-08-08T05:18:14 < cjbaird> Reimaging the FAT partition part, anyway.
2012-08-08T05:19:10 < karlp> yeah, but I don't reall feel like learning enough of the image generation and build steps to do that.
2012-08-08T05:19:19 < karlp> it's the least fun part of linux
2012-08-08T05:21:28 < cjbaird> http://elinux.org/RPi_Kernel_Compilation ..was my guide
2012-08-08T05:32:03 < cjbaird> Something Japanese I can't stand: sake .. It's down there with lagers and bourbon.

2012-08-08T12:12:02 <+dekar__> dongs, I am pretty sure win8 needs ARMv7 or higher
2012-08-08T12:12:18 <+dekar__> you could probably run dosbox and boot win95 though
2012-08-08T12:12:30 <+Steffanx> And who wants to boot win95 ?!?!
2012-08-08T12:12:39 <+dekar__> dongs maybe?
2012-08-08T12:12:59 <+Steffanx> He is crazy/weird, but THAT crazy/weird?
2012-08-08T12:13:24 <+dekar__> it probably is more useful than win8 for arm anyway
2012-08-08T12:13:36 <+dekar__> I mean you can't run any native applications on win8-arm
2012-08-08T12:13:39 <+Steffanx> win8 isn't useful at all

2012-08-08T15:13:09 < zyp> cjbaird, what inspired you to make udon?
2012-08-08T15:13:24 < karlp> the tastiness?
2012-08-08T15:17:05 < cjbaird> Mostly from this: http://www.myrecipes.com/recipe/chicken-udon-soup-50400000118586/ ... motivation: the latest episode of the chinese cartoon "Space Brothers"
2012-08-08T15:17:48 < cjbaird> Was very tasty, but then I cheat and use MSG. :)
2012-08-08T15:18:03 < zyp> ha, that's what I suspected
2012-08-08T15:18:11 < zyp> I've also watched that episode :p
2012-08-08T15:18:59 < Oldboy> does MSG help in a Chicken soup ?
2012-08-08T15:19:02 <+Steffanx> You guys and your 'MSG'
2012-08-08T15:19:57 < Oldboy> msg simulates the 'taste' of meat (protein) doesn't it ?
2012-08-08T15:20:38 < cjbaird> Yup, the fifth taste sense 'savory/umami'
2012-08-08T15:21:12 < cjbaird> Makes a good alternative to regular salt, at least.
2012-08-08T15:22:10 <+Steffanx> I want more than 'standard' MSG in my food i go to McDonalds :P
2012-08-08T15:22:19 <+Steffanx> *If I
2012-08-08T15:22:55 <+Steffanx> I mean, you won't see me add more of that crap in my food
2012-08-08T15:23:37 < cjbaird> It's pretty-much impossible to get MSG-laden food around here in AU .. A big xenophobic push against it in the early 1980s pretty-much had it removed from everything. :/
2012-08-08T15:24:30 < cjbaird> I have a stack of /nasty/ food additives in my kitchen :D .. MSG, Maltodextrin, Xanthian Gum, ... Lots of fun to play with.
2012-08-08T15:25:50 < cjbaird> Xanthian is great for making jellies out of anything (vodka..), as a general thickener, and preventing ice-crystals forming in homemade ice-cream and such.
2012-08-08T15:26:12 < Oldboy> MSG flavored Xantian gum trests.

2012-08-08T15:27:25 <+Steffanx> Xanthian .. me doesn't know that

2012-08-08T20:45:18 < karlp> I dunno, how many of the modplayer _playing_ things were written with portability in mind, and not trying to fit into demo scene code size limits?
2012-08-08T20:45:46 < karlp> actually, if you just ask in #demoscene or something, they'll probably know which mod players are portably small, rather than x86 asm full of tricks
2012-08-08T20:48:06 < zippe> Yeah, the only ones I've found so far are the mod-only player that Rockbox uses, and Dumb, which seems too big and evil

2012-08-09T16:20:16 <+Steffanx> unused - This attribute, attached to a variable, means that the variable is meant to be possibly unused. GCC will not produce a warning for this variable.

2012-08-09T16:23:18 <+Steffanx> True
2012-08-09T16:23:30 < karlp> that would also have to be on the variable in the function def
2012-08-09T16:23:35 < karlp> which wouldn't do the same thing

2012-08-09T19:41:54 < zyp> pin compatible doesn't mean they can't add new functions
2012-08-09T19:41:59 < dongs> ok.
2012-08-09T19:42:34 <+dekar> are AVR fuses permanently gone once blown?
2012-08-09T19:42:39 <+Steffanx> no
2012-08-09T19:43:10 <+dekar> okay, I flashed some attiny45 using my buspirate today and was wondering
2012-08-09T19:43:24 <+dekar> I love the buspirate btw
2012-08-09T19:43:39 <+Steffanx> which version you have?
2012-08-09T19:43:40 <+Steffanx> 4?
2012-08-09T19:43:55 <+dekar> 3 I think
2012-08-09T19:44:35 < dongs> dekar: you can change them
2012-08-09T19:44:43 < dongs> unless you fuck up and set no SPI or no reset fuse etc.
2012-08-09T19:44:48 < dongs> or wrong crystal choice...
2012-08-09T19:44:56 < dongs> then you need to connect hvpp shit.
2012-08-09T19:45:01 < dongs> avr is so fucking retarded.
2012-08-09T19:45:54 <+dekar> I think I set the no-reset one
2012-08-09T19:46:02 < karlp> that's a bad one.
2012-08-09T19:46:20 < karlp> you've got to realllllly want that last io pin to set that fuse
2012-08-09T19:46:26 <+dekar> I needed the reset pin for i2c
2012-08-09T19:46:44 <+Steffanx> How you're screwed :P
2012-08-09T19:46:48 <+Steffanx> *now
2012-08-09T19:46:58 < dongs> you better hope your shit is bugfree.
2012-08-09T19:47:16 <+dekar> it was some precompiled firmware so I guess it it
2012-08-09T19:47:18 <+dekar> *it is
2012-08-09T19:47:22 < dongs> oh.
2012-08-09T19:47:54 <+dekar> building a few of those: http://www.harbaum.org/till/i2c_tiny_usb/index.shtml
2012-08-09T19:47:58 <+Steffanx> Why you need that pin for i2c?
2012-08-09T19:48:26 <+dekar> Steffanx, cause there were no others left, it only has like 4 GPIO pins
2012-08-09T19:48:31 <+dekar> 2 for usb, and 2 for i2c
2012-08-09T19:48:36 <+Steffanx> Yes i know, but sw i2c?
2012-08-09T19:48:52 < zyp> and sw usb :p
2012-08-09T19:49:01 <+dekar> yeah both sw :)
2012-08-09T19:49:25 <+Steffanx> I'm glad i never used that, v-usb/other sw usb implementation
2012-08-09T19:50:07 <+dekar> https://dl.dropbox.com/u/28467113/IMAG0125.jpg
2012-08-09T19:50:14 <+dekar> any idea what corrupted the last bit?
2012-08-09T19:50:23 <+Steffanx> oldskool scope
2012-08-09T19:50:35 <+dekar> I wonder whether that's caused by the zener diodes
2012-08-09T19:50:59 <+dekar> Steffanx, it works
2012-08-09T19:51:12 <+dekar> also does 500mhz
2012-08-09T19:51:13 <+Steffanx> I didn't say anything about THAT
2012-08-09T19:52:07 <+dekar> somehow I get USB errors plugging the tiny in :/

2012-08-09T19:53:08 < jpa-> dekar: what is the top signal?
2012-08-09T19:53:20 <+dekar> jpa-, the difference between D+ and D-
2012-08-09T19:53:24 < jpa-> it's normal that USB packet is terminated in non-differential 0
2012-08-09T19:53:37 < zyp> yes
2012-08-09T19:53:38 <+dekar> oh is it? I didn't know that
2012-08-09T19:53:47 < zyp> usb have four bus states
2012-08-09T19:54:21 < zyp> the differential ones are called J and K, and then you have SE0 and SE1
2012-08-09T19:54:38 < jpa-> http://en.wikipedia.org/wiki/USB#Signaling
2012-08-09T19:54:40 < zyp> and packets are terminated by SE0
2012-08-09T19:55:14 <+dekar> thanks, so that doesn't seem to be the problem then
2012-08-09T20:03:58 < zyp> hmm, your trace shows a SOF packet :p
2012-08-09T20:04:09 < dongs> wth is that
2012-08-09T20:04:10 < dongs> usb?
2012-08-09T20:04:13 < zyp> yes
2012-08-09T20:04:19 < dongs> how the fuck can you tell just by looking
2012-08-09T20:04:50 < dongs> how the fuck does zyp walk upright with that big brain of his
2012-08-09T20:05:08 < zyp> the PID field reads 0101, and I looked it up - it's SOF
2012-08-09T20:05:52 < zyp> anyway, SOF is sent by the host, so that doesn't really indicate that the AVR is doing anything
2012-08-09T20:08:18 < zyp> the only thing the host needs to detect presence of a device is the pullup on one of the data lines, and as soon as it can see that it will start spewing a lot of activity on the bus
2012-08-09T20:08:52 <+Steffanx> Time to get an uc with proper usb peripheral dekar :P
2012-08-09T20:09:04 <+Steffanx> -n
2012-08-09T20:09:10 <+dekar> that's why windows tried to install drivers from screwdrivers plugged into the USB bus! :D
2012-08-09T20:09:43 < zyp> would it really?
2012-08-09T20:09:51 <+dekar> a co-worker told me it would
2012-08-09T20:10:01 <+Steffanx> Never believe co-workers
2012-08-09T20:10:04 <+dekar> hehe
2012-08-09T20:10:10 < Thorn> how can it do that without knowing vid/pid first?
2012-08-09T20:10:12 <+Steffanx> Especially with stories like that
2012-08-09T20:10:21 < zyp> Thorn, exactly
2012-08-09T20:10:22 < Thorn> it needs to pull the descriptor for that
2012-08-09T20:10:37 <+Steffanx> it IS windows .. :P
2012-08-09T20:10:59 <+Steffanx> An OS that surprises you over and over again
2012-08-09T20:11:11 < Thorn> ("the descriptor" isn't really correct, is it. "a shitload of descriptors" is better)
2012-08-09T20:12:49 < zyp> you don't need «a shitload of descriptors» to use usb
2012-08-09T20:13:17 < zyp> it will enumerate fine with only a device descriptor
2012-08-09T20:13:47 <+dekar> I get some "device not accepting address" in dmesg
2012-08-09T20:14:12 < zyp> yep
2012-08-09T20:14:19 <+dekar> would I get that as well if the attiny did nothing?
2012-08-09T20:14:27 < karlp> I used one of those tiny usb devices for a while, I regularly had problems with it,
2012-08-09T20:14:33 < zyp> dekar, I believe so
2012-08-09T20:15:02 < zyp> first the host will try reading the start of the device descriptor, and then it will assign the device an address
2012-08-09T20:15:50 < zyp> the host probably tries assigning an addr even if reading the descriptor fails, to cope with quirky devices
2012-08-09T20:16:12 < Thorn> why this address, it it used anywhere?
2012-08-09T20:16:47 < zyp> Thorn, every unit on an USB bus needs to have an address
2012-08-09T20:18:46 < Thorn> do usb hubs do routing or something based on this address?
2012-08-09T20:19:01 < zyp> no, hubs are just hubs
2012-08-09T20:20:47 < zyp> I'm not sure about the magic to handle different speeds, but other than that, they propagate the same traffic to all ports
2012-08-09T20:21:18 < karlp> they do?
2012-08-09T20:21:23 < zyp> yep
2012-08-09T20:21:51 < Thorn> so devices need to do packet filtering like ethernet interfaces do?
2012-08-09T20:22:07 < zyp> surprised me as well when I was using a USB analyzer downstream of the same hub that the st-link was plugged into, picked up st-link traffic as well
2012-08-09T20:22:10 < zyp> Thorn, yes
2012-08-09T20:23:51 < karlp> huh, today's full of learning
2012-08-09T20:24:26 <+dekar> for me too, thanks a lot for the lesson :)
2012-08-09T20:26:42 < zyp> http://bin.jvnv.net/f/ruxN0.png <- found a screenshot from when I was working on enumeration
2012-08-09T20:26:50 < zyp> note the addr sent in the Dev column
2012-08-09T20:27:30 < zyp> device responds correctly to the first two commands, but I hadn't implemented address changing yet
2012-08-09T20:28:38 < Thorn> I need a usb analyzer

2012-08-09T20:33:21 < zyp> isn't the LS/FS beagle rather affordable?

2012-08-09T20:47:41 < zyp> by the way, if you're using linux you can use wireshark to capture usb traffic on host ports without any special hardware
2012-08-09T20:48:48 <+dekar> nice, does that work for low level stuff as well? Like for the case where the slave doesn't respond?

2012-08-10T00:16:38 < Tectu> karlp, last time i looked, there was no C/C++ plugin downloadable for netbeans, because their link was broken :D

2012-08-10T00:17:53  * karlp shrugs
2012-08-10T00:18:02 < karlp> I'm not currently trying to install it. ;)
2012-08-10T00:18:33 < Tectu> karlp, that was the only reason which hold me back from using it
2012-08-10T00:18:48 < Tectu> karlp, anyways, not much people use it. are you happy with it? is it "better" than eclipse?
2012-08-10T00:18:59 < karlp> I find it simpler cleaner and faster.
2012-08-10T00:19:04 < zyp> IDE this, IDE that :)
2012-08-10T00:19:27 < karlp> I actually started using netbeans because it had python support as well as c/c++
2012-08-10T00:19:39 < Tectu> zyp, this is my "IDE" ;-)   http://i.imgur.com/uhjJJ.png
2012-08-10T00:19:44 < karlp> netbeans has now dropped python, and isn't doing a good job of looking after C (thanks for nothing oracle)
2012-08-10T00:20:01 < karlp> so I'm fairly open to alternatives, but eclipse isn't cutting it for me yet.
2012-08-10T00:20:09 < karlp> and I go back and try it out again every now and again
2012-08-10T00:21:07 < zyp> Tectu, yeah, isn't that integrated enough?
2012-08-10T00:21:30 < Tectu> zyp, a little bit too much for my taste ;-)
2012-08-10T00:21:37 < karlp> Tectu: what are those tests running on the right?
2012-08-10T00:21:59 < Tectu> karlp, that were a few of my first steps with ChibiOS and that is the benchmark output of chibiOS
2012-08-10T00:22:11 < Tectu> it does provide a benchmark with a nice output, as you can see ;-)
2012-08-10T00:22:29 < zyp> did you write them, or did they come with chibios?
2012-08-10T00:22:32 < karlp> can you write your own tests?
2012-08-10T00:22:47 < DLPeterson> Can anybody here give me a bit of guidance on implementing a timer interrupt handler which must process multiple input capture and update events?
2012-08-10T00:23:02 < Tectu> zyp, also i have VLC integrated in my IDE ...   http://i.imgur.com/wjvdq.jpg
2012-08-10T00:23:10 < Tectu> they come with chibiOS
2012-08-10T00:23:29 < zyp> DLPeterson, just check the status flags in the interrupt handler
2012-08-10T00:23:38 < Tectu> you just call one function    TestThread()  and then it does a lot of tests / benchmarkes and outputs them through serial console
2012-08-10T00:23:45 < Tectu> and since my ChibiOS-LCD-Driver also over LCD ;-)
2012-08-10T00:24:09 < zyp> Tectu, is that for ruby on rails development? :p
2012-08-10T00:24:10 < DLPeterson> zyp, should I clear and process all of the ones that are in the SR?  i.e., if there is more than one set.
2012-08-10T00:24:24 < Tectu> zyp, lol!
2012-08-10T00:24:31 < Tectu> zyp, that's the movie  "Unstoppable"
2012-08-10T00:24:59 < Tectu> which i bought.
2012-08-10T00:25:03 < zyp> DLPeterson, do you have the reference manual open? are the interrupt status flags of type r_w1?
2012-08-10T00:25:40 < zyp> in that case, you read SR to a temporary variable, then write it back to clear the read flags
2012-08-10T00:25:55 < zyp> then you execute actions based on the flags set in the temp variable
2012-08-10T00:26:06 < DLPeterson> zyp, I have RM0008 open.  No they are rc_w0.
2012-08-10T00:26:37 < zyp> oh, ok
2012-08-10T00:26:50 < feurig> is there a simple code sample for estimating how much free memory is avaliable during run time
2012-08-10T00:26:51 < DLPeterson> zyp, where are those terms defined?
2012-08-10T00:26:56 < zyp> then read it and write them to 0 immediately after writing
2012-08-10T00:27:04 < zyp> in the beginning of the document
2012-08-10T00:27:28 < zyp> r_w0 is «write 0 to clear», r_w1 is «write 1 to clear»
2012-08-10T00:28:02 < Tectu> zyp, what does rc_w0 mean?  write 1 to clear and the c?
2012-08-10T00:28:03 < DLPeterson> zyp, Should I handle all the interrupts that are set in one single call to the handler, or just one at a time.  I seem to remember something about interrupts being pended.
2012-08-10T00:28:03 < zyp> the latter is preferable, because then you can write back the ones you just captured
2012-08-10T00:28:45 < zyp> DLPeterson, both is possible, handling all at once would be more efficient
2012-08-10T00:29:15 < feurig> like you can in avr-gcc by checking the location of a recently allocated variable against __bss_end or __brkval?
2012-08-10T00:29:29 < zyp> DLPeterson, http://cgit.jvnv.net/suzumebachi/tree/drivers/ppmsum.cpp <- here is how I do it
2012-08-10T00:30:01 < DLPeterson> zyp, ok.  Suppose 2 of the interrupt flags are set in the SR.  If I clear both and take appropriate action, will the handler still get called again since there were two interrupts?
2012-08-10T00:30:03 < zyp> feurig, as I said, it depends on your sbrk implementation
2012-08-10T00:30:34 < zyp> DLPeterson, no
2012-08-10T00:30:53 < zyp> DLPeterson, the handler will get called again as long as there is any active interrupt flags set
2012-08-10T00:30:55 < feurig> can you put that in c? and explain?
2012-08-10T00:30:58 < feurig> zyp:
2012-08-10T00:31:32 < feurig> I am using libmaple
2012-08-10T00:31:38 < zyp> feurig, sbrk() is a function, newlib is using that function to get memory for malloc(), it should maintain a variable equal to __brkval
2012-08-10T00:31:48 < zyp> find the implementation of sbrk() and find out what it calls that variable
2012-08-10T00:32:06 < zyp> I have no idea how libmaple's sbrk() looks
2012-08-10T00:32:28 < zyp> the equivalent of __bss_end is defined in the linker script
2012-08-10T00:32:40 < zyp> find the linker script and check there
2012-08-10T00:32:45 < DLPeterson> zyp, so your PPSum::irq() handler uses if (...) {...} else if (...) {...} else if(...) { ...}.  Doesn't this mean that if TIM1.SR had more than one of the flags set that you would still only process one of them?  And effectively ignore the others, since you are doing TIM1.SR=0;?
2012-08-10T00:32:57 < feurig> zyp: thanks.
2012-08-10T00:33:05 < zyp> DLPeterson, yes, but in my case they can't happen at the same time
2012-08-10T00:33:17 < DLPeterson> zyp, ok.
2012-08-10T00:34:05 < DLPeterson> zyp, I don't know if they can happen at the same time in my case, so do you advise making my control logic similar to yours but without the else?
2012-08-10T00:34:15 < zyp> one trigger on a rising edge while the other trigger on a falling edge of the same signal
2012-08-10T00:36:43 < zyp> the only difference of using else or not in my case is that if the first flag is set, it will return directly after instead of checking if the other flags are set
2012-08-10T00:37:50 < zyp> the code would work exactly the same without the else part, but it would take a few more instructions in most cases
2012-08-10T00:38:51 < zyp> I don't think I put that much thought into efficiency when I wrote it though :p

2012-08-10T05:15:49 < DLPeterson> dongs, do you use an RTOS; if so which one?
2012-08-10T05:17:16 < zippe> DLPeterson: dongs is above, or beneath most RTOS'
2012-08-10T05:17:45 < DLPeterson> zippe: I sort of gathered that from his comment :)
2012-08-10T05:17:53 < zippe> DLPeterson: others here have opinions too though… if you want them 8)
2012-08-10T05:18:32 < DLPeterson> zippe: sure, what do you think of RTOS, which ones have you tried, and which do you like/dislike the most?
2012-08-10T05:19:25 < zippe> I use several for different purposes
2012-08-10T05:19:28 < zippe> Tools for the job
2012-08-10T05:19:45 < zippe> Currently I'm doing a lot with NuttX
2012-08-10T05:19:56 < zippe> For small jobs I like scmRTOS
2012-08-10T05:20:42 < zippe> They're two ends of the spectrum, really.  scmRTOS is very tight, not a whole lot beyond the scheduler and messaging.
2012-08-10T05:21:07 < zippe> With NuttX sometimes you can forget and think you're on a Posix system
2012-08-10T05:21:16 < karlp> have you ever used contiki?
2012-08-10T05:21:37 < zippe> A little.  I had a lot of trouble with tools so I didn't get as much done as I'd like.
2012-08-10T05:21:58 < zippe> It's less an RTOS and more an operating system.
2012-08-10T05:22:26 < zippe> But at the same time it forces you to think a little more carefully, since it's co-operatively scheduled.
2012-08-10T05:22:46 < DLPeterson> scmRTOS looks interesting, I didn't even know there were RTOS's implemented entirely in C++
2012-08-10T05:22:47 < karlp> yeah, I was more thinking OS than RTOS,
2012-08-10T05:22:54 < karlp> I don't do much that needs the RT part.
2012-08-10T05:23:05 < karlp> but I'm interested in the ipv6 "magically it all works" stuff
2012-08-10T05:23:08 < zippe> DLPeterson: I am basically sold on embedded C++
2012-08-10T05:23:27 < zippe> DLPeterson: There are lots of pieces of C++ the language that I can do without
2012-08-10T05:23:44 < DLPeterson> zippe: Me too.  I'm using C++ for all my embedded application development.
2012-08-10T05:23:58 < zippe> But you get compiler support for a bunch of things that you'd otherwise be forced to do by hand.
2012-08-10T05:24:21 < DLPeterson> zippe: not any of the fancy stuff of course.  But classes and such are quite handy, and if you are smart about how you use them they don't add bloat.
2012-08-10T05:24:39 < zippe> Right.  Constructors for stack objects are also quite useful
2012-08-10T05:25:01 < zippe> I can't go anywhere without an interrupt-disable class these days. 8)
2012-08-10T05:25:12 < karlp> interrupt disable class?
2012-08-10T05:25:18 < karlp> what's that help you with?
2012-08-10T05:25:30 < DLPeterson> zippe: I've been using a bunch of singleton's for a lot of my classes, I guess that is similar to a constructor for a stack object, right?
2012-08-10T05:25:50 < zippe> karlp: you create a class whose constructor disables interrupts, and whose destructor enables them (or really, use a global interrupt disable count)
2012-08-10T05:25:58 < DLPeterson> zippe: Do you have code example's of the interrupt-disable class?
2012-08-10T05:26:13 < zippe> karlp: Then anytime you want interrupts disabled, you just declare an instance of the class.
2012-08-10T05:26:31 < zippe> karlp: Interrupts are immediately disabled, and they stay disabled until the object goes out of scope
2012-08-10T05:26:37 < zippe> karlp: sec, I'll dig one out
2012-08-10T05:26:38 < DLPeterson> zippe: ah, cool.  and when it goes out of scope it re-enables interrupts... so you can use scope blocks.
2012-08-10T05:26:46 < zippe> DLPeterson: exactly
2012-08-10T05:27:01 < DLPeterson> zippe: I think I've seen a thread locker class similar to that.
2012-08-10T05:27:08 < karlp> I guess a scope block and a special var is easier to follow than C's set/clear at the beginning and end of the sections?
2012-08-10T05:27:15 < zippe> then you can do things like measure how long you spend with interrupts off
2012-08-10T05:27:30 < DLPeterson> zippe: neat.
2012-08-10T05:27:31 < zippe> karlp: The advantage is that you can return out of the middle of the block and the compiler takes care of re-enabling interrupts
2012-08-10T05:27:37 < karlp> ahhh
2012-08-10T05:27:48 < zippe> karlp: it becomes impossible to mis-match interrupt-disable calls
2012-08-10T05:27:51 < karlp> so you don't have to worry about all the linux kernel goto stuff to help with cleanup.
2012-08-10T05:28:00 < zippe> karlp:  *exactly*
2012-08-10T05:28:06 < karlp> clever :)
2012-08-10T05:28:13 < zippe> karlp: it helps
2012-08-10T05:28:44 < DLPeterson> zippe: what is your typical use case for this class? Inside interrupt handlers?
2012-08-10T05:30:05 < zippe> DLPeterson: anytime you want to lock against interrupts / pre-emption
2012-08-10T05:30:19 < zippe> e.g. when messing with data that you share with interrupt context
2012-08-10T05:30:34 < zippe> I use lockless constructs when I can, but you can't always
2012-08-10T05:30:41 < zippe> Here's the class from scmRTOS
2012-08-10T05:30:41 < zippe> class TCritSect
2012-08-10T05:30:42 < zippe> {
2012-08-10T05:30:42 < zippe> public:
2012-08-10T05:30:42 < zippe>     TCritSect () : StatusReg( SREG ) { cli(); }
2012-08-10T05:30:42 < zippe>     ~TCritSect() { SREG = StatusReg; }
2012-08-10T05:30:42 < zippe>     //~TCritSect() { if( StatusReg & (1 << SREG_I)) sei(); }
2012-08-10T05:30:43 < zippe> private:
2012-08-10T05:30:43 < zippe>     status_reg_t StatusReg;
2012-08-10T05:30:44 < zippe> };
2012-08-10T05:31:04 < zippe> (that's AVR code)
2012-08-10T05:31:34 < zippe> No nesting or instrumentation there, but you get the idea
2012-08-10T05:31:49 < DLPeterson> zippe: cool.
2012-08-10T05:33:19 < zippe> Are you looking for anything in particular in a system, or just browsing?
2012-08-10T05:34:42 < DLPeterson> Well, at the moment I'm somewhat committed to ChibiOS, but I'm definitely curious about other options.
2012-08-10T05:35:01 < DLPeterson> Have you used ChibiOS?
2012-08-10T05:36:06 < karlp> is scmRTOS the public output of some company?
2012-08-10T05:36:46 < DLPeterson> I'm using the ChibiOS shell and it's SD card functionality and integration with FatFS.. it was relatively painless to get that part up and running, which was really nice and a big part of why I chose it.
2012-08-10T05:37:48 < DLPeterson> Also, the ChibiOS forum support has been really, really good.  And the documentation is good.  So for a rookie like me, these are all convincing reasons for me to use it.

2012-08-10T05:50:04 < upgrdman> stm32f4 disco board: anyone know why they didn't debounce the blue pushbutton? the series resistor is there, but the cap was left off... wtf?
2012-08-10T05:52:17 < zippe> karlp: Not AFAIK
2012-08-10T05:52:37 < zippe> DLPeterson: I looked at it a while back; at the time it was basically a thread scheduler and some drivers
2012-08-10T05:52:41 < karlp> just curious, the team's all russian
2012-08-10T05:52:53 < karlp> upgrdman: probably just copied it all the way from 32VL disco?
2012-08-10T05:53:15 < zippe> karlp: Could be.  Their english is OK and I see they finally translated the v4 manual.
2012-08-10T05:53:37 < zippe> upgrdman: disco board was designed by interns, I think
2012-08-10T05:53:50 < dongs> chibios is commie? yet more reasons to not like it.
2012-08-10T05:53:59 < karlp> scmRTOS, not chibios dongs
2012-08-10T05:54:03 < dongs> ah
2012-08-10T05:54:12 < dongs> i heard that one too i think.
2012-08-10T05:55:26 < upgrdman> zippe, :)
2012-08-10T05:55:49 < upgrdman> well considering the price, i put up with it. but the docs... so much room for improvement
2012-08-10T05:56:12 < DLPeterson> zippe: can ask you an interrupt question?
2012-08-10T05:56:50 < zippe> Can I stop you? 8)
2012-08-10T05:56:54 < DLPeterson> :)
2012-08-10T05:57:50 < DLPeterson> If you are processing an interrupt and you've cleared the bits in the peripherals interrupt that triggered it, and then that same peripheral gets another interrupt, what happens?

2012-08-10T05:58:25 < karlp> what more could you ask for?
2012-08-10T05:59:11 < upgrdman> karlp, not the docs for that, but in general. especially rm0090.
2012-08-10T05:59:19 < DLPeterson> is the handler going to finish, and then get called again, or something else?
2012-08-10T05:59:22 < karlp> man, nuttx page is full of typos...

2012-08-10T06:00:22 < karlp> more of the who hell comes up with that shit
2012-08-10T06:00:26 < zippe> Agh, Devices don't get interrupts
2012-08-10T06:00:49 < zippe> DLPeterson: But in general, if the device recognises an interrupting condition, it will re-assert the interrupt output
2012-08-10T06:00:59 < zippe> DLPeterson: Normally when you're servicing an interrupt, it remains masked
2012-08-10T06:01:20 < zippe> DLPeterson: So when you return from the interrupt and it's unmasked, you will immediately re-enter the interrupt handler
2012-08-10T06:01:42 < DLPeterson> zippe: ok.  That makes sense.
2012-08-10T06:02:46 < DLPeterson> I mean to say that the peripheral triggers another interrupt, whilst the CPU is in the middle of processing an interrupt from same peripheral.
2012-08-10T06:02:49 < DLPeterson> meant.
2012-08-10T06:03:01 < zippe> karlp: let Greg know if you find typos, he's pretty good about fixing stuff
2012-08-10T06:03:16 < zippe> DLPeterson: yeah, I thought that's what you meant, just being pedantic 8)
2012-08-10T06:03:36 < DLPeterson> zippe: it's good to be precise, thanks for keeping me in check.
2012-08-10T06:03:50 < zippe> It's kind of you to confuse pedantry with precision 8)
2012-08-10T06:07:19 < karlp> eh, how do I find an email for this greg character?
2012-08-10T06:07:27 < karlp> you've shamed me into doing something about the typos
2012-08-10T06:08:43 < karlp> right, so my mrf24j40 code now works properly with function pointers instead of being avr specific.
2012-08-10T06:08:51 < karlp> now I can try and merge the stm32 and avr blobs
2012-08-10T06:09:12 < karlp> we're getting somewhere, even if using function poitners adds 15-20% code space to the sample project

2012-08-10T14:03:33 < cjbaird> I read it around 1990, but I suspect the mag was already a few years old. But certainly still in the time of its high of popularity with the Computer Recreations column.

2012-08-10T21:24:48 < DLPeterson> Does anybody know if the 'reserved' bits of a register are guaranteed to be high or low?  I'm reading one of the capture compare register in a timer and it has the upper half word reserved.
2012-08-10T21:25:19 < DLPeterson> I'm wondering if I need to mask them out just to be certain, or if I can rely on them being low.
2012-08-10T21:27:04 <+Steffanx> They datasheets gives the reset values AND states you shouldn't change them
2012-08-10T21:28:05 <+Steffanx> it seems, after a quick scan, they're all 0
2012-08-10T21:28:45 <+Steffanx> */They/The
2012-08-10T21:33:41 < DLPeterson> Steffanx: it doesn't seem to give reset states for reserved areas of registers, unless I'm just am looking in the wrong place.  My guess is that they would be all 0 but I just wanted to know if that was guaranteed by hardware
2012-08-10T21:35:06 < Thorn> it pays to be paranoid. doing foo & 0x0F or whatever isn't difficult
2012-08-10T21:35:40 < Thorn> as a general rule
2012-08-10T21:35:42 <+Steffanx> Aren't you sure you don't modify them anyway?
2012-08-10T21:36:07 < DLPeterson> Thorn: yeah, that is what I was thinking.
2012-08-10T21:36:20 < DLPeterson> Steffanx: I don't modify them in my code, I only read them
2012-08-10T21:37:29 <+Steffanx> https://skitch.com/steffann/em983/a when i read that .. 0x0000 i would that's 16 bits, which also says the reserved area is all 0
2012-08-10T21:37:36 <+Steffanx> *would say
2012-08-10T21:38:21 <+Steffanx> I COULD be wrong though
2012-08-10T21:41:57 < zyp> on a general basis, reserved bits are not guaranteed to be anything, that's why they are reserved
2012-08-10T21:43:32 <+Steffanx> unless the ds states otherwise :P
2012-08-10T21:46:50 < zyp> for registers holding a single integral value that's smaller than the full 32 bits, it's usually safe to assume that the topmost bits always reads as 0
2012-08-10T21:47:05 < zyp> for instance the counter registers of 16-bit counters
2012-08-10T21:47:29 < zyp> 32-bit counters have the same registers, except the topmost part is no longer reserved

2012-08-11T06:49:03 < cjbaird> Ha-- I just soldered all the leftover lengths of solder I'd had in the box, and made a single continuous length of about 22 metres. And I'd thought I'd just ran out...
2012-08-11T07:07:27 < LeelooMinai> I'm just starting with stm32 - is there some documentation for standard peripheral library that would contain examples and general description of usage patterns for it?
2012-08-11T07:14:27 < R2COM> which peripherals you need?
2012-08-11T07:15:36 < LeelooMinai> I need documentation on everything that that library provides - so I can actually start programming the uC:)
2012-08-11T07:15:53 < R2COM> you downloaded the one fromST already?
2012-08-11T07:16:02 < R2COM> it has most of the peripherals with coded examples
2012-08-11T07:16:16 < R2COM> however, its done using the STDperiph driver...
2012-08-11T07:16:37 < LeelooMinai> Well, I downloaded Attolic Studio IDE with STM32 support
2012-08-11T07:16:55 < LeelooMinai> But I don't see any info about the library there
2012-08-11T07:17:17 < R2COM> you mean you do not see any functions or drivers?
2012-08-11T07:17:27 < LeelooMinai> Also, I have F0 discovery board... and there's a download for the library on st site, but somehow it's for the F1 series not F0
2012-08-11T07:17:52 < LeelooMinai> Well, I can see headers and sources included into projects, but no documentation
2012-08-11T07:18:29 < LeelooMinai> Isn't there like a PDF dexcribing how to use those libraries?
2012-08-11T07:19:07 < R2COM> i tried finding it, i didnt, i found some Html shit, but that wasnt much helpful, i literally started from scratch debugging the peripheral and trying to make it work.
2012-08-11T07:19:43 < R2COM> and well, im not using standard driver, i use register definitions to talk to peripherals
2012-08-11T07:20:28 < LeelooMinai> Heh... wonderful:p
2012-08-11T07:20:44 < R2COM> it is. once it works.
2012-08-11T07:21:17 < LeelooMinai> Sure, I will figure it out... but this route will take time
2012-08-11T07:22:31 < R2COM> it might take a while if one needs USB etc, but for others i dont think its that bad
2012-08-11T07:23:05 < LeelooMinai> I guess I will see - ok, thx
2012-08-11T07:23:41 < R2COM> one of the nastiest peripheral i guess is I2c
2012-08-11T07:26:03 < LeelooMinai> Hmm... weird thing is I just downloaded this library for F0 from st site and it's version 1.0.0 ... while Atolic IDE has version 1.0.1 inside...
2012-08-11T07:27:17 < R2COM> if you want to use library just as a first time reference, to see which registers it sets to configure peripherals it doesnt matter much.
2012-08-11T07:29:09 < LeelooMinai> Right
2012-08-11T07:29:53 < LeelooMinai> BTW, Can I just use Discovery board as a programmer, or is there a point in buying this ST LINK v2 for #5 or so?
2012-08-11T07:29:59 < LeelooMinai> for $25 that is*
2012-08-11T07:30:21 < R2COM> i used discovery board to program stm32 on another custom board, it works. i used SWD
2012-08-11T07:30:44 < R2COM> just unplug two CN3 jumpers
2012-08-11T07:31:06 < R2COM> discovery manual shows pin connection for SWD
2012-08-11T07:31:08 < LeelooMinai> Yes, so this programmer would be basically same + maybe Jtag, nice case, and some cables included?
2012-08-11T07:31:19 < R2COM> I am not sure about Jtag
2012-08-11T07:31:32 < LeelooMinai> It has this 20 pin jtag cable in there
2012-08-11T07:31:49 < R2COM> you are talking about standalone one? maybe.
2012-08-11T07:32:23 < LeelooMinai> http://www.futureelectronics.com/en/technologies/development-tools/development-tool-hardware/Pages/3008294-ST-LINK-V2.aspx?IM=0
2012-08-11T07:32:26 < LeelooMinai> ^ Yes, this one
2012-08-11T07:32:44 < R2COM> well, if you really need jtag then maybe yes
2012-08-11T07:34:19 < R2COM> but those tools if you use them as is, are 32Kb limited, you need custom toolchain if you want bigger code
2012-08-11T07:34:37 < LeelooMinai> Which tools?
2012-08-11T07:34:43 < R2COM> the Atollic?
2012-08-11T07:34:50 < R2COM> its free but with 32Kb code limit
2012-08-11T07:34:59 < LeelooMinai> A, right, yes, I know
2012-08-11T07:35:15 < LeelooMinai> I think 32kB will be fine for my next few projects

2012-08-12T03:44:12 < upgrdman> externally clocked counters have two modes. is the only difference that mode 2 can have a prescaler? (and fewer pins support that mode) ... stm32f4
2012-08-12T03:46:37 < zyp> you mean TRGI vs ETRF?
2012-08-12T03:51:34 < zyp> looks like the second mode has some other magic too, the filter stuff
2012-08-12T03:53:15 < upgrdman> yes. trgi had the filter too
2012-08-12T03:53:52 < upgrdman> (both trgi and etrf have a 4bit filter)
2012-08-12T03:54:12 < zyp> I haven't used external clock sources myself yet, so I don't know more than what I can read from the reference manual
2012-08-12T03:54:23 < upgrdman> ok
2012-08-12T03:54:39 < upgrdman> its the ref man that im reading too. it just seems like the only diff is a prescaler
2012-08-12T03:55:10 < zyp> figure 133 doesn't show a flter for TRGI
2012-08-12T03:55:30 < zyp> like the one in figure 135 for ETRF
2012-08-12T03:55:37 < upgrdman> yes it does... its the first block in 133
2012-08-12T03:55:44 < zyp> oh, right
2012-08-12T03:56:17 < zyp> but it doesn't have the ck_int input
2012-08-12T03:56:32 < upgrdman> both modes work as expected for me... im just surprised they made two modes, and only a few pins support etrf
2012-08-12T03:56:53 < zyp> ah
2012-08-12T03:57:26 < zyp> well, as long as it works as expected, it's not really something to worry about :p
2012-08-12T03:57:30 < upgrdman> i know
2012-08-12T03:57:53 < upgrdman> i dont even need these modes. but im learning, and trying to so all of the exampled in the timer chapter in an effort to learn.
2012-08-12T04:01:16 < upgrdman> theres no defintions for bits 9-15 for SMCR... wtf stm
2012-08-12T04:01:28 < upgrdman> 8-15

2012-08-12T21:14:45 < Tectu> TitanMKD, wait, what?
2012-08-12T21:14:53 < Tectu> TitanMKD, you design an F4 board?
2012-08-12T21:14:56 < Tectu> or a case? o0
2012-08-12T21:43:37 < TitanMKD> Tectu it is a board with a case ;)
2012-08-12T21:44:36 < Tectu> TitanMKD, d you already have anything?

2012-08-12T22:11:06 < Tectu> TitanMKD, ?
2012-08-12T22:11:38 < TitanMKD> i'm finalizing the pcb ;)
2012-08-12T22:11:46 < TitanMKD> but i have already the components
2012-08-12T22:23:25 < Tectu> TitanMKD, so how about some more informations?
2012-08-12T22:35:14 -!- barthess [~barthess@178.154.10.243] has joined ##stm32
2012-08-12T22:54:35 < TitanMKD> Tectu i'm designing it and it's very hard to output all signal on just 60mm*37mm pcb with only 2 layers ;)
2012-08-12T22:55:26 < Tectu> TitanMKD, i know, but can you PLEASE give me now a bit of more informations so i can tell you if i am interested or not? :D
2012-08-12T22:56:40 < zyp> is it just some kind of a breakout board?
2012-08-12T22:59:10 < Tectu> zyp, wouldn't have a case then, i guess
2012-08-12T23:00:05 < zyp> so it's just supposed to sit inside the case and do nothing?
2012-08-12T23:01:20 < TitanMKD> Tectu it is planned to route all signal PA, PB and PC and also including Lipo manager for autonomous board
2012-08-12T23:01:32 < TitanMKD> Tectu including 1 USB
2012-08-12T23:01:55 < Tectu> TitanMKD, so you already have some screenshots / list of features and PRICING?
2012-08-12T23:02:41 < zyp> wtf is «autonomous board»?
2012-08-12T23:04:48 < TitanMKD> zyp for example to connect it to a NFC stuff with display ...;)
2012-08-12T23:05:19 < TitanMKD> in fact it was intended to be connected to my TRF7970A Breakout Board but now it is a bit more universal
2012-08-12T23:05:31 < zyp> I'm not sure I get the point?
2012-08-12T23:06:14 < Tectu> zyp, he means it runs on battery :(
2012-08-12T23:06:16 < TitanMKD> it's a board based on LQFP64 STM32F405RGT
2012-08-12T23:06:32 < TitanMKD> but anyway it will also support power over USB
2012-08-12T23:06:41 < TitanMKD> without Lipo
2012-08-12T23:07:03 < zyp> well, yeah
2012-08-12T23:07:11 < TitanMKD> i will check if the lipo stuff can be optional and left unsoldered for those which do not want that feature
2012-08-12T23:07:16 < zyp> but is that the whole point of the board?
2012-08-12T23:07:46 < Tectu> zyp, maybe it just belongs to the titans
2012-08-12T23:07:48 < TitanMKD> it is just exactly same size of Bus Pirate v3.6
2012-08-12T23:08:00 < TitanMKD> and can also replace a buspirate for fast signal
2012-08-12T23:08:02 < Tectu> TitanMKD, and what is it's purpose, we are still asking the same -.-
2012-08-12T23:08:37 < TitanMKD> Tectu it is multipurpose board with chibios embedded and a terminal you can do what you want with access on all peripherals
2012-08-12T23:09:07 < TitanMKD> like plug additional board in sandwich to add SDIO, SDCARD ...
2012-08-12T23:09:10 < zyp> so, it's a breakout board with a voltage regulator capable of being powered both by usb and lipo?
2012-08-12T23:09:19 < TitanMKD> zyp yes
2012-08-12T23:09:31 < Tectu> TitanMKD, and it costs how much and why should we get one
2012-08-12T23:10:08 < TitanMKD> the cost is very low because the most expensive is the STM32F4
2012-08-12T23:10:51 < TitanMKD> anyway with little production (less than 100 units) it will cost really more than STM32F4 Discovery
2012-08-12T23:11:01 < TitanMKD> and even for 100units it will cost more than 20USD
2012-08-12T23:12:12 < TitanMKD> I as planning to use a CPLD to have simplify routing but it will be even harder on such a little board
2012-08-12T23:12:19 < TitanMKD> I as => I was
2012-08-12T23:13:00 < zyp> to simplify routing?
2012-08-12T23:13:53 < TitanMKD> yes because routing of 48 GPIO in order PA0 to PA15 ... on only 2 layers is a challenge ;)
2012-08-12T23:14:44 < TitanMKD> I will probably rearrange the IO to be more straight to the STM32F4 ;)
2012-08-12T23:14:49 < zyp> using a cpld won't really give you any huge benefit
2012-08-12T23:15:09 < zyp> and add a lot of complexity that you probably don't want
2012-08-12T23:15:19 < zyp> and also remove some features that you might want
2012-08-12T23:15:25 < TitanMKD> zyp yes for such simple design it is not interesting
2012-08-12T23:15:47 < zyp> you can't route analog signals for the ADC through the CPLD
2012-08-12T23:16:11 < TitanMKD> zyp yes and also bidir signal are tricky on CPLD
2012-08-12T23:16:12 < zyp> and IO direction is defined by the CPLD, so it's not as easy to change
2012-08-12T23:16:44 < zyp> and then there is the hassle of actually making and loading the CPLD configuration :p
2012-08-12T23:16:59 < TitanMKD> yes CPLD stuff will be for an other design ;)
2012-08-12T23:17:37 < zyp> did you see the F4 board I made?
2012-08-12T23:17:41 < TitanMKD> I have not even added the LIPO stuff but IIRC it take less space than a regulator
2012-08-12T23:17:43 < zyp> with a CPLD on it :p
2012-08-12T23:17:52 < TitanMKD> ha ?
2012-08-12T23:17:57 < TitanMKD> have you a link ?
2012-08-12T23:18:06 < zyp> sure
2012-08-12T23:18:26 < zyp> http://bin.jvnv.net/f/sTW8U.JPG
2012-08-12T23:18:50 < zyp> I thought everybody had seen it by now :p
2012-08-12T23:19:22 < TitanMKD> woo seems pretty cool
2012-08-12T23:19:35 < TitanMKD> where are the spec ?
2012-08-12T23:19:41 < zyp> which spec?
2012-08-12T23:19:46 < TitanMKD> of this board
2012-08-12T23:20:04 < zyp> I haven't written any spec, this is just a hobby project that I'm not intending to sell
2012-08-12T23:20:48 < TitanMKD> just to know what it does
2012-08-12T23:22:09 < zyp> it's intended as a quadrotor controller, got the F4, gyro, accelerometer, magnetometer, air pressure sensor and gps
2012-08-12T23:22:20 < TitanMKD> ha great
2012-08-12T23:22:41 < TitanMKD> stm32f4 seems perfect for that especially with the DSP ;)
2012-08-12T23:22:54 < zyp> connectivity is usb, xbee socket, can transceiver and a bunch of remappable pins capable of transceiverless can, spi, uart and pwm in/out
2012-08-12T23:23:13 < zyp> the CPLD is responsible for the remappable pins
2012-08-12T23:23:17 < TitanMKD> ha remappable pins are managed by the CPLD/FPGA ?
2012-08-12T23:23:24 < TitanMKD> yes very good
2012-08-12T23:23:34 < zyp> not only for routing, but also logic like simulating can transceivers for transceiverless can
2012-08-12T23:23:38 < zyp> or uart muxing
2012-08-12T23:23:51 < TitanMKD> and why not debugging ;)
2012-08-12T23:24:02 < zyp> oh, and there is a jtag/swd port of course
2012-08-12T23:24:23 < TitanMKD> I plan to only add SWD on mine
2012-08-12T23:25:06 < zyp> it's the same pins, and I have leftover GPIOs so I don't need them for other purposes
2012-08-12T23:25:24 < TitanMKD> IIRC JTAG use more pins
2012-08-12T23:26:11 < zyp> yes, one or two, depending on whether you count SWO or not
2012-08-12T23:26:44 < TitanMKD> i will check depending on space left ;) JTAG could be better
2012-08-12T23:26:46 < zyp> if I went with only SWD, I'd still want SWO, so in reality I'd only save JTDI if I eliminated JTAG
2012-08-12T23:28:02 < zyp> going by experience, SWD is faster than JTAG, so that's what I normally use
2012-08-12T23:28:26 < zyp> but I wouldn't know that if I designed this board with SWD only, because then I wouldn't be able to test that :p
2012-08-12T23:28:43 < Tectu> zyp, SWD would be a no-go for me
2012-08-12T23:28:44 < TitanMKD> anyway i have all pins available on connector
2012-08-12T23:28:58 < TitanMKD> Tectu why it is a no-go ?
2012-08-12T23:29:05 < zyp> Tectu, because you only have a shitty debugger probe that doesn't support SWD? :p
2012-08-12T23:29:34 < Tectu> zyp, correct, but please don't point that out :D
2012-08-12T23:29:47 < TitanMKD> Tectu if you already have a Stm32F4Discovery you can use the SWD debugger to debug other board
2012-08-12T23:30:11 < TitanMKD> and I have never found a JTAG debugger for less than 12USD ;)
2012-08-12T23:30:52 < zyp> except using a discovery board as a debugger for other stuff usually results in a mess of wires
2012-08-12T23:31:01 < Tectu> probably i should get some black magic
2012-08-12T23:31:02 < zyp> that's what I hated about it :p
2012-08-12T23:31:46 < Tectu> zyp, lol. I do have dedicated stlink v2 at the moment
2012-08-12T23:31:52 < Tectu> zyp, which one do you have/use
2012-08-12T23:32:45 < zyp> http://bin.jvnv.net/f/MNigG.JPG <- using a discovery board towards a board with a standard 0.05" header usually turns out like this
2012-08-12T23:35:44 < zyp> I got tired of trying to remember and end up having to check which pins where which every time I wanted to hook it up to something

2012-08-12T23:59:16 < Tectu> is it worth to get a black magic?
--- Day changed Mon Aug 13 2012
2012-08-13T00:00:14 < zyp> that's up to you
2012-08-13T00:00:54 < Tectu> how much did you pay for it?
2012-08-13T00:01:06 < Tectu> has it some more features than stlink? (software)
2012-08-13T00:01:13 -!- phantoxeD [~destroy@a95-92-89-24.cpe.netcabo.pt] has joined ##stm32
2012-08-13T00:02:19 < zyp> I don't remember what I paid
2012-08-13T00:03:02 < Tectu> i have something in mind that people said it is faster than the 10kB/s of stlink
2012-08-13T00:03:06 < Tectu> is that true ?
2012-08-13T00:03:58 < zyp> yes, I believe it reaches 45 kB/s or so
2012-08-13T00:04:15 < Tectu> dongs said he has some 2Mbps, is that true? o0
2012-08-13T00:04:20 < Tectu> not sure if he uses black magic
2012-08-13T00:04:53 < zyp> no, flash is not capable of writing 2 MB/s in any case
2012-08-13T00:05:06 < zyp> and no, I believe he's mainly using jlink
2012-08-13T00:05:29 < Tectu> maybe it was erasing he was talking of
2012-08-13T00:05:33 < Tectu> about*
2012-08-13T00:05:36 < zyp> irrelevant
2012-08-13T00:06:18 < Tectu> well then
2012-08-13T00:06:20 < zyp> you can probably say that the largest feature of the blackmagic is that it runs the entire gdbserver on the dongle itself
2012-08-13T00:06:33 < Tectu> huh
2012-08-13T00:06:39 < Tectu> what is the adventage of that?
2012-08-13T00:06:44 < zyp> it enumerates as a serial port, so you just attach gdb directly to that
2012-08-13T00:07:22 < Tectu> what is the adventage of that? o0
2012-08-13T00:07:51 < zyp> that you don't need to run some kind of middleware between gdb and the dongle
2012-08-13T00:09:42 < zyp> it's also less quirky and more robust than stlink and the texane middleware
2012-08-13T00:09:51 < Tectu> so i don't need texane anymore?
2012-08-13T00:09:56 < zyp> correct
2012-08-13T00:10:01 < Tectu> texane always drops connection :D
2012-08-13T00:10:44 <+Steffanx> You need a bmp and gdb
2012-08-13T00:10:46 <+Steffanx> and a pc ofcourse :P
2012-08-13T00:10:51 <+Steffanx> With 'random' OS
2012-08-13T00:11:05 < Tectu> so no driver hacking with linux since serial port
2012-08-13T00:11:13 < zyp> blackmagic handles disconnects nicely (like when the target MCU loses power), while stlink tends to lock up or just get confused and return random data
2012-08-13T00:11:57 < Tectu> and gsmcmullin is the guy behind black sphere technologies, right?
2012-08-13T00:12:00 < Tectu> so is it his "invention"?
2012-08-13T00:12:03 < zyp> yes
2012-08-13T00:12:23 < Tectu> the new version dosen't seem to have some jtag
2012-08-13T00:12:49 < zyp> doesn't it?
2012-08-13T00:12:52 <+Steffanx> it has
2012-08-13T00:13:01 <+Steffanx> "Standard 10-pin Cortex debug connector for connection to the target with JTAG or SWD."
2012-08-13T00:13:17 <+Steffanx> It just doesn't have this big ass connector anymore
2012-08-13T00:13:28 < Tectu> does it have an adaptor?
2012-08-13T00:13:37 < zyp> having the big connetor is kind of nice
2012-08-13T00:13:52 < zyp> since the waveshare board I bought uses that :p
2012-08-13T00:14:33 < Tectu> yeah
2012-08-13T00:14:35 < Tectu> same here
2012-08-13T00:14:41 < Tectu> zyp, how do you connect it up to the BMP??
2012-08-13T00:15:05 < zyp> look in my picture, see how I got both the small and the big connector? :p

2012-08-13T00:15:36 < Tectu> that's not fair :D
2012-08-13T00:16:13 < Tectu> why do you need a USB hub with on/off switches per port? o0
2012-08-13T00:16:53 <+Steffanx> Where do you read that?
2012-08-13T00:17:05 < zyp> Steffanx, it's also visible in the picture :p
2012-08-13T00:17:14 < Tectu> Steffanx, http://bin.jvnv.net/f/yQGUT.JPG
2012-08-13T00:17:22 < Tectu> zyp, so?
2012-08-13T00:17:36 < zyp> saw it in a store in japan, thought it would be nice to have, so I picked it up
2012-08-13T00:17:37 <+Steffanx> Oh, that
2012-08-13T00:18:03 < zyp> it's nice to be able to turn off a port rather than have to unplug and replug it for any reason
2012-08-13T00:18:45 < zyp> having to replug stuff when doing usb related development is rather common
2012-08-13T00:19:00 <+Steffanx> Just a switch in the power lines? :P
2012-08-13T00:19:02 <+Steffanx> -s
2012-08-13T00:19:52 < zyp> yeah, likely
2012-08-13T00:20:16 < zyp> I imagine anything actually cutting the data lines would be unnecessary expensive
2012-08-13T00:20:42 < Tectu> and leak performance
2012-08-13T00:21:01 <+Steffanx> Maybe some fancy usb hub chip with extra functionality?
2012-08-13T00:21:08 < zyp> so if vbus for some reason remains powered on the device side, or device remains powered and ignores vbus state, it can probably still pass data
2012-08-13T00:21:09 < Tectu> Steffanx, to expensive
2012-08-13T00:21:23 <+Steffanx> Only when it says "Made in China"
2012-08-13T00:21:26 < zyp> but that doesn't really matter for me
2012-08-13T00:21:37 < zyp> hmm
2012-08-13T00:21:41 < zyp> it actually says that
2012-08-13T00:21:48 < zyp> like everything else :p
2012-08-13T00:23:25 < zyp> I also picked up another hub that has a micro connector on the host side
2012-08-13T00:24:18 < zyp> so it plugs directly into the OTG connector on the F4discovery board and allows other devices to be connected to it
2012-08-13T00:24:49 < zyp> also has external power input, so it's possible to use it with OTG hosts that's uncapable of supplying vbus
2012-08-13T00:25:20 <+Steffanx> Fancy
2012-08-13T00:25:52 < zyp> it's intended for smartphones and tablets
2012-08-13T00:26:19 < zyp> figured it'll be nice to have if/when I decide to play with host mode in my stack :p
2012-08-13T00:26:31 <+Steffanx> In Japan they use their smartphones for everything ofcourse
2012-08-13T00:26:54 < zyp> oh, I dunno
2012-08-13T00:28:47 < zyp> one of my friends remarked that a lot of the japanese people we saw on trains seemed to have both a smartphone and a normal japanese phone
2012-08-13T00:31:11 < zyp> looked like that for a lot of people the smartphone was just a toy to pass time with, and then they preferred their old phone for it's tasks
2012-08-13T00:31:17 < zyp> or something like that
2012-08-13T00:45:20 < zyp> dongs, did you know you've always wanted this? http://www.kickstarter.com/projects/digistump/digispark-the-tiny-arduino-enabled-usb-dev-board
2012-08-13T00:45:49 <+Steffanx> zyp, reads #sparkfun too
2012-08-13T00:46:15 <+Steffanx> So i'll quote myself: "Yet another 'useless' project on kickstarter"
2012-08-13T00:46:36 <+Steffanx> and make it useless without the quotes
2012-08-13T00:47:02 < Tectu> how comes that people get so much money with these projects :(
2012-08-13T00:48:27 < zyp> they come up with something that the masses want
2012-08-13T00:49:04 <+Steffanx> What masses what..
2012-08-13T00:49:06 <+Steffanx> want
2012-08-13T00:50:00 <+Steffanx> Too many buy crap as long as it has "arduino" on it :P
2012-08-13T00:54:12 <+Steffanx> it's also attiny45 based .. so crap usb included ..
2012-08-13T00:54:31 < zyp> attiny85 actually
2012-08-13T00:54:38 < zyp> but that's just a 45 with more flash
2012-08-13T00:54:57 <+Steffanx> oh, yes you are right
2012-08-13T00:55:25 < zyp> sloppy soldering in the pics too
2012-08-13T00:55:44 < zyp> not as bad as that tom guy, but still

2012-08-13T02:36:46 <+dekar_> what I don't get about that tiny arduino board, as well as the arduino itself is that most hobbyists probably don't care whether the µC costs $1 or $5
2012-08-13T02:37:21 <+dekar_> so why get the small ones with heavy memory constrains?
2012-08-13T02:38:12 < zyp> because they don't know better
2012-08-13T02:43:38 <+dekar_> another huge downside is the lack of an USB-PHY, I don't think there are many CPU cycles left for actually using that as a prototyping device :/
2012-08-13T02:43:55 < zyp> huh?
2012-08-13T02:44:08 < zyp> it's really more about the MAC than the PHY :p
2012-08-13T02:44:13 <+dekar_> isn't that kickstarter thing bitbanging usb?
2012-08-13T02:44:45 <+dekar_> oh right, that's what I meant
2012-08-13T02:45:02 < zyp> the «PHY» is a couple of resistors or so :p
2012-08-13T02:45:32 <+dekar_> yeah USB phy isn't that hard :)
2012-08-13T02:45:41 < zyp> not for LS
2012-08-13T02:45:44 <+dekar_> is it called MAC for USB?
2012-08-13T02:46:34 < zyp> MAC is a term in the OSI model, which also applies to USB
2012-08-13T02:50:26 <+dekar_> that attiny usb to i2c thing I recently built only supports up to 50khz i2c speeds. the only thing it does is bitbang usb as well as i2c
2012-08-13T02:51:01 <+dekar_> so I imagine that tiny arduino will perform equally bad
2012-08-13T02:51:07 < zyp> yeah
2012-08-13T02:51:28 < zyp> but if all you want to do is blink some leds, it's good enough
2012-08-13T02:51:51 < zyp> I'd be more concerned about the number of available pins
2012-08-13T02:55:46 <+dekar_> they had to resort to an i2c display since that thing lacks the pins to drive a parallel hd44780
2012-08-13T02:56:34 < zyp> which is just hd44780 with another microcontroller to translate i2c to parallel, right? :p
2012-08-13T02:58:19 <+dekar_> yeah :/
2012-08-13T02:58:32 <+dekar_> http://www.pjrc.com/teensy/index.html
2012-08-13T02:58:45 <+dekar_> those things are dirt cheap as well, a much better choice imo
2012-08-13T02:59:31 < zyp> I got a box of atmega32u4s sitting around
2012-08-13T03:00:34 <+dekar_> I've actually never worked with any 8bit µC, but I imagine you'd often get problems porting C libraries
2012-08-13T03:01:05 < zyp> why?
2012-08-13T03:01:17 <+dekar_> I mean most applications just assume sizeof(int) to be at least 32bit
2012-08-13T03:01:45 < zyp> most applications won't fit on a MCU
2012-08-13T03:02:39 < zyp> and variable sizes is decided by the compiler, not the platform
2012-08-13T03:02:40 <+dekar_> I actually had no problem grabbing random libraries and using them on my stm32 so far
2012-08-13T03:02:57 < zyp> which libraries?
2012-08-13T03:03:23 <+dekar_> libtomcypt and lua
2012-08-13T03:06:01 < dongs> factory fucked up and rotated every pcb in my panel 90 degrees
2012-08-13T03:06:07 < dongs> and dicknplace software doesn't rotate data
2012-08-13T03:06:09 < dongs> wat2do
2012-08-13T03:06:22 < zippe> rotate the panel?
2012-08-13T03:06:26 < dongs> I can export shit as csv, is tehre any way to do a x/y rotation in excel or somethingf
2012-08-13T03:06:29 < zippe> Or did you use a rectangular panel?
2012-08-13T03:06:29 < dongs> cant
2012-08-13T03:06:30 < dongs> the guides are wrong way
2012-08-13T03:06:40 < zippe> *snrk*
2012-08-13T03:06:45 < dongs> *I* didnt , they fucked up.
2012-08-13T03:06:52 < zippe> Now, if the pnp software was opensource, you could just add the feature...
2012-08-13T03:06:57 < dongs> it is opensource.
2012-08-13T03:07:01 < dongs> but i am not touching VB6.
2012-08-13T03:07:05 <+dekar_> lol
2012-08-13T03:07:25 <+dekar_> open source pick and place software? link?
2012-08-13T03:07:32 <+dekar_> any free license?
2012-08-13T03:07:36 < dongs> the dude was here last time to fix shitty bugs and left the sores.
2012-08-13T03:07:44 <+dekar_> I see
2012-08-13T03:07:49 < dongs> trust me, you dont want it.
2012-08-13T03:07:58 < dongs> the only reason I haven't rewritten it is because its fucking filthy.
2012-08-13T03:08:35 < dongs> they do machine "vision" by putpixel/getpixel in VB.
2012-08-13T03:08:41 < dongs> and comparing brightness or something.
2012-08-13T03:09:30 < dongs> no proper algorithms, shit is buggy etc. typical japanese code.
2012-08-13T03:10:50 < zyp> what about complaining and demanding correct panels?
2012-08-13T03:10:58 < dongs> not worth the trouble
2012-08-13T03:11:29 <+dekar_> zyp, so you can tell the compiler to have 32bit int on a 8bit architecture? I guess the performance penalty would be quite high, but I see that being useful
2012-08-13T03:11:42 < zyp> dekar_, sure, why not?
2012-08-13T03:11:43 < dongs> dekar, just use uint32_t / int32_t?
2012-08-13T03:12:01 <+dekar_> dongs, well we were talking about porting existing libs
2012-08-13T03:12:02 < zyp> dekar_, avr-gcc has 16-bit ints by default
2012-08-13T03:12:44 < dongs> dekar, there are worthwhile tarduino libs to be ported?
2012-08-13T03:12:53 < zyp> and any sensible lib should have specific integer sizes for cases where it matters
2012-08-13T03:13:19 < dongs> so yeah uh...
2012-08-13T03:13:21 < dongs> how2rotate this shit
2012-08-13T03:13:50 < dongs> i could export all xy positions as dots to a bitmap, rotate bitmap in mspaint, get the x/y pixels back out.. but thats tedious and annoying.
2012-08-13T03:13:59 <+dekar_> zyp, in reality many aren't developed with less than 32bit architectures in mind (or big endian)
2012-08-13T03:14:32 < zyp> dongs, you swap x and y cols, then make one of them negative
2012-08-13T03:14:43 < zyp> and then add a constant to each row again to align it
2012-08-13T03:15:02 < dongs> wat
2012-08-13T03:15:03 < zyp> which col to make negative depends on whether you're rotating clockwise or counterclockwise
2012-08-13T03:15:14 < dongs> its a 90" rottaion not 180
2012-08-13T03:15:33 < zyp> well, duh, 180 means making both cols negative
2012-08-13T03:16:39 < dongs> ok so lets say i have a part at 11,16
2012-08-13T03:16:43 < dongs> i swap them 16,11
2012-08-13T03:16:50 < dongs> what does this offset do?
2012-08-13T03:16:56 < dongs> offset will have to be -5?
2012-08-13T03:17:10 < zyp> no
2012-08-13T03:17:18 < zyp> offset is the point you're rotating around
2012-08-13T03:17:27 < dongs> that would be the center of pcb i guesss
2012-08-13T03:17:51 < zyp> if you don't add any offset, you're rotating around the origin, i.e. point 0,0
2012-08-13T03:18:58 < zyp> that's why a point at 5, 5 would be at 5, -5 or -5, 5 when you rotate it
2012-08-13T03:19:28 < dongs> so if my pcb is 20,20mm can I do offset 10,10 then?
2012-08-13T03:19:36 <+dekar_> dongs, I wasn't actually planning to port any arduino libs or the like. I just meant so far I had no trouble using off the shelf C libraries on my stm32 and I'd imagine you'd have trouble doing that on a 8bit architecture.
2012-08-13T03:19:39 < dongs> to rotate around center?
2012-08-13T03:20:04 < zyp> dongs, you can do x = y and y = 20 - x
2012-08-13T03:20:05 < dongs> dekar_: actually you can ,  generally, as zyp said any worthwhile lib will have used correct sized types without assuming shit when it needs to
2012-08-13T03:20:06 <+dekar_> But I guess it actually makes no difference
2012-08-13T03:20:17 < zyp> or x = 20 - y, and y = x
2012-08-13T03:20:27 < dongs> zyp, is that to get offset? or to rotate
2012-08-13T03:20:33 < zyp> both
2012-08-13T03:20:49 < zyp> one is clockwise, other is counterclockwise, I'm too tired to figure out which is which

2012-08-13T06:41:50 < dongs> besides , all the analog gyros i've seen you dont amplify. the only reason to have an opamp there is to reduce output impedance maybe, not to amp it.
2012-08-13T06:42:26 < dongs> cause usually gyro shit is like > 30-50k ohm output impedance. so you have a opamp on the output without actually amplifying anything

2012-08-13T08:20:59 < dongs> not as bad as some of the shit laurenceb says.
2012-08-13T08:21:32 < feurig> would be nice if there were moderators
2012-08-13T08:22:19 < dongs> i dont really agree
2012-08-13T08:22:43 < dongs> people are entitled to an opinion.
2012-08-13T08:22:53 < dongs> i dont think banning someone for an opinion makes sense.
2012-08-13T08:23:02 < dongs> this is irc, if you dont liek something you have 2 options: 1) /ignore 2) /part
2012-08-13T08:23:10 < dongs> noone is forcing you to listen to me
2012-08-13T08:23:33 < feurig> this is a public forum where people are supposed to be helping eachother
2012-08-13T08:23:45 < dongs> I don't see you doing enough helping then.
2012-08-13T08:24:00 < feurig> so some things like blatant sexism really dont help
2012-08-13T08:24:08 < dongs> oh wtf now
2012-08-13T08:24:21 < feurig> thats exactly what I said.
2012-08-13T08:25:47 < dongs> i have no idea what youre tlaking about.
2012-08-13T08:26:02 < feurig> when someone says their cowworker is upset and your advice ist to rape her I dont see that as being helpful in any way
2012-08-13T08:26:22 < dongs> dude, knowing Laurenceb its probably his fantasy
2012-08-13T08:26:36 < dongs> also: getting offended at sexist shit on irc? seriously, wtf
2012-08-13T08:26:59 < feurig> promoting and participating it WTF.
2012-08-13T08:27:19 < feurig> anyways would be nice to see some channel ops here but oh well.

2012-08-13T15:48:58 < cjbaird> Yep. Not too long ago I found a supplier that's like 50% the price of usual retail, ~$5/kilo. 3 tubs of that for $15 can make about 15-18 litres of finished mead, and still manages to save me a fuckload on booze. :P

2012-08-13T16:29:15 < dongs> but its a lame hash, etc.
2012-08-13T16:29:21 < dongs> plus keygen and check are both in the code
2012-08-13T16:29:28 < ABLomas> heh
2012-08-13T16:30:15 < ABLomas> too bad i do not have lots of time (to get exp with IDA, last used 7 years ago, damn, i do not have time to test baseflight GPS as promised) - would be nice to check what this AP does...
2012-08-13T16:30:17 < dongs> ill wait until he goes into full production wiht those lame green boards of his
2012-08-13T16:30:30 < dongs> then publish the info somewehre.
2012-08-13T16:30:40 < dongs> or maybe after he fixes some more bugs
2012-08-13T16:30:44 < dongs> there's nothing interesting in teh code..
2012-08-13T16:31:37 < ABLomas> then it will change protection and...
2012-08-13T16:31:48 < dongs> yes, but all old shit will work.
2012-08-13T16:31:50 < dongs> shrug
2012-08-13T16:32:05 < ABLomas> anyway, if i solder test board (doubt i will find time for that) - will you make one key for my processor hasr?
2012-08-13T16:32:08 < ABLomas> *hash
2012-08-13T16:32:35 < dongs> i could, just dont expect it immediately
2012-08-13T16:32:48 < zyp> I expect it yesterday!
2012-08-13T16:32:53 < ABLomas> sure
2012-08-13T16:32:59 < ABLomas> i'm slow builder anyway
2012-08-13T16:34:18 < dongs> youre not missing much
2012-08-13T16:34:26 < dongs> if you want OSD you gotta use that retarded hk_osd bits
2012-08-13T16:34:35 < dongs> cause he refuses to invert signal from lm1881
2012-08-13T16:34:46 < dongs> so basically its either "make shit the way I ghetto it up or fuck off"
2012-08-13T16:35:01 < ABLomas> ;-)
2012-08-13T16:35:09 < ABLomas> i'm not making money of my business
2012-08-13T16:35:13 < ABLomas> so just testing stuff
2012-08-13T16:35:21 < ABLomas> actually do not care ;-)
2012-08-13T16:35:32 < dongs> the demo mode lets you fuck around
2012-08-13T16:35:34 < dongs> without a key.
2012-08-13T16:35:56 < dongs> the check is just done once at boot or someshit.
2012-08-13T16:35:59 < dongs> and some byte is set.
2012-08-13T16:36:15 < dongs> he's got someshit like if (demomode) osd_print("LOLDEMO");
2012-08-13T16:36:24 < dongs> after that it took like 2 minutes to find the check code/keygen/etc.
2012-08-13T16:37:05 <+izua_> cjbaird: that's pretty ghetto
2012-08-13T16:39:31 < cjbaird> You /could/ pay $1000+ for the Rich White Man gear from online stores...

2012-08-13T21:58:36 < zyp> emeb, is that four layers?
2012-08-13T21:58:43 < emeb> zyp: no - just two.
2012-08-13T21:58:52 < zyp> and no ground plane?

2012-08-13T22:00:05 < zyp> it's not «mostly ground plane» when it's sliced into separate sections by traces with just a little bit of connection
2012-08-13T22:00:41 <+izua> emeb: do you work with dsp?
2012-08-13T22:00:43 < Thorn> I'd definitely pour both sides and stitch the pieces together
2012-08-13T22:00:58 < zyp> Thorn, yes
2012-08-13T22:00:59 <+izua> any recommended reading for guitar effects and such, except zolzer's books?
2012-08-13T22:01:20 < emeb> izua: yes - a lot of dsp.
2012-08-13T22:01:23 <+izua> they are sparse at the very least.
2012-08-13T22:01:38 <+izua> i'm curious how people like those from amplitube or guitar rig get such epic software
2012-08-13T22:01:38 < emeb> zyp: it's not too badly sliced up.
2012-08-13T22:02:20 < zyp> the point of a ground plane is to provide a low impedance return path for signals by letting it run directly underneath
2012-08-13T22:02:44 < zyp> you kind of ruin that when you have a crossing trace underneath that the return path have to take a long detour around

2012-08-13T22:03:22 < zyp> and you still didn't add a fill on the top? :p
2012-08-13T22:04:39 < Thorn> I think ST appnotes recommend 4 layers for all stm32 designs, so one should at least try and provide a ground plane
2012-08-13T22:06:01 < emeb> If this were a production board going into volume application I'd definitely pop for 4 layers w/ internal GND/VDD. But it's a hobby board for proof of concept.
2012-08-13T22:06:55 <+Steffanx> Hobby bobby: +1 :)
2012-08-13T22:07:53 <+Steffanx> A little mistake near PA1 emeb ?

2012-08-13T22:08:35 < zyp> but that's less important than a good ground :p

2012-08-13T22:09:59 < emeb> ohnoes - a stub in the line. we'll have horrible edge effects.
2012-08-13T22:10:10 < zyp> I see that you also opted to leave out the ID pin on the usb connector
2012-08-13T22:10:10 <+Steffanx> Yeah, you are dooomed
2012-08-13T22:10:34 < emeb> zyp: yep - no ID. Device only.
2012-08-13T22:10:44 < Thorn> and esd protection
2012-08-13T22:10:58 < emeb> Thorn: true enough.
2012-08-13T22:11:18 <+Steffanx> Who needs esd protection on a hobby bobby board?
2012-08-13T22:11:20  * Thorn is rubbing his synthetic shirt
2012-08-13T22:12:15 < emeb> and no ESD protection on any of the misc expansion connectors. Or EMC filters. Or... Or...
2012-08-13T22:13:58 < emeb> The next big fun thing will be trying to get the SD interface working.
2012-08-13T22:14:13 < zyp> SDIO?
2012-08-13T22:14:29 < emeb> I've hooked up both the SDIO and one of the SPI ports for that.
2012-08-13T22:14:43 < emeb> I figure that I can hi-z the one I don't use. Thoughts?
2012-08-13T22:15:41 < zyp> should be fine
2012-08-13T22:15:57 < Thorn> you just don't enable clock for the peripheral you don't use if I get you right
2012-08-13T22:16:14 < zyp> irrelevant
2012-08-13T22:16:20 <+izua> but he could use the SPI GPIO
2012-08-13T22:16:31 < zyp> you just leave the IO lines in input modes and it's fine
2012-08-13T22:17:05 < emeb> I assumed that since SD has only 4 bits that means hooking up D0-3 of the SDIO port.
2012-08-13T22:17:15 < emeb> D4-7 unused...
2012-08-13T22:22:34 < zyp> probably
2012-08-13T22:22:50 < zyp> IIRC 8-bit SDIO is equivalent to what is used for MMC
2012-08-13T22:23:11 < zyp> and then there is also 1-bit SDIO mode
2012-08-13T22:24:08 < emeb> zyp: have you used SDIO <-> SD or do you just go SPI?
2012-08-13T22:24:29 < zyp> neither, I don't have any experience on interfacing with SD cards
2012-08-13T22:24:30 < zyp> yet
2012-08-13T22:24:58 < zyp> but I would go with SDIO, I don't see any reason for using SPI when SDIO is available
2012-08-13T22:25:06 < emeb> I've done SPI->SD on a dsPIC and on an old LPC ARM. Works OK.
2012-08-13T22:25:29 < emeb> But I'd like to have things go as fast as possible in this app, so SDIO option is good to have.
2012-08-13T22:25:42 < zyp> I put a microsd socket on the last AVR board I made, hooked up to SPI, but I never wrote the software to use it
2012-08-13T22:26:14 < emeb> been there. Always nice to throw in extra goodies for possible use.
2012-08-13T22:26:44 < emeb> The USB on this board is like that - no real reason, but I had room and the sockets in the parts bin.
2012-08-13T22:27:36 < zyp> opposite for me, USB is pretty central on my board as a fast data pipe
2012-08-13T22:28:02 < zyp> so it was the first thing I got going
2012-08-13T22:30:25 < emeb> did you put on a USB ESD protection part? I've used them in production boards but not this time.
2012-08-13T22:30:30 < zyp> nah
2012-08-13T22:30:45 < zyp> like you said, why protect usb when nothing else is protected?
2012-08-13T22:31:21 < zyp> if the internal TVS diodes in the chip is good enough for the other pins, it's good enough for the USB pins too
2012-08-13T22:32:31 < emeb> ESD performance of most commercial parts these days is pretty good compared to 30 years ago when things would die if you looked at them funny.
2012-08-13T22:34:01 < zyp> yeah
2012-08-13T22:34:42 < zyp> I don't think I've killed anything of the stuff I'm playing with, and I'm not particularly careful
2012-08-13T22:34:52 < emeb> Same here.

2012-08-13T23:07:46 < karlp> no esd protection? ;)
2012-08-13T23:09:59 < zyp> looks like if I've got a pending transfer in TXFIFO 1 and then put another transfer in TXFIFO 0, while the host wants to transfer from endpoint 0, I get the data meant for endpoint 1 sent from endpoint 0
2012-08-13T23:12:04 < zyp> not really sure why that happens, but it explains why my script fails to find the device the second time I run it, it gets some messed up data from the last bulk transfer rather than the device descriptor

2012-08-14T00:22:54 < emeb> I found something else odd while working on the I2S - I had to create two separate DMA_InitStructure instances when configuring the TX and RX I2S streams. When I tried to reuse just one then everything failed.
2012-08-14T00:30:00 < zyp> I'm accessing registers directly, so that doesn't apply to me
2012-08-14T00:31:25 < emeb> Yep - your peripheral access libs are a lot cleaner than the ST ones.
2012-08-14T00:32:14 < zyp> that's the point :p
2012-08-14T00:33:03 < emeb> I did an experiment a while back - coded an app w/ ST libs, then did it with raw access. Cut the code size down to about 25% of original.

2012-08-14T05:35:29 < dongs> i fucking hope htey dont follow GNU indent style
2012-08-14T05:41:38 < zippe> Nope.  Pretty standard KNF, actually.

2012-08-14T05:43:59 < dongs> but maybe they have some custom JPL stdjplint.h
2012-08-14T05:44:13 < zippe> But really, if that's all there is to bitch about, it's a damn good doc

2012-08-14T05:46:11 < dongs> surely its not named that retardedly?
2012-08-14T05:46:19 < zippe> Because underscore-capital is the reserved namespace
2012-08-14T05:46:22 < zippe> You had better believe it
2012-08-14T05:46:36 < dongs> is it _True and _False then too?

2012-08-14T05:53:23 < cjbaird> I've also discovered that the current SAT (I forgot to note if with linaro-4.6 or stock gcc) is producing bad code on my project with -O3 .. O2, Os are fine.

2012-08-14T09:43:10 < cjbaird> 'a serious muffin' .. Unlike the past few day's experiments (with standard recipes from books) this one was properly muffiny-- I used self-raising flour and just the one egg; the book recipes wanted plain flour+baking powder and 2-3 eggs-- and they always turned out heavy and sticky.
2012-08-14T09:45:13 < cjbaird> Pity that strawberries are fuckexpensive. Might have to look around for cheaper suitable fruits.

2012-08-14T10:15:02 < zippe> It may or may not DTRT with the 'interrupt' attribute
2012-08-14T10:15:43 < zyp> huh? naked attribute on all handlers?
2012-08-14T10:15:46 < cjbaird> This is for the libopencm3 code, not 'my' vectors.
2012-08-14T10:16:30 < dongs> libopencm3 more like libFAILcm3
2012-08-14T10:16:39 < dongs> though open is generally synonymous with fail anyway.

2012-08-14T10:19:14 < Thorn> and your asm is portable between all toolchains, rite
2012-08-14T10:19:24 < dongs> thorn, its only portable to the toolchain that matters
2012-08-14T10:19:25 < zyp> reset handler shouldn't require any special treatment either, as long as the cpu loads a valid stack pointer from the vector table at boot
2012-08-14T10:19:39 < dongs> Thorn: and libopencm3 is portable to all compilers, rite

2012-08-14T10:26:08 < cjbaird> I think there's an errata about ldaim.w failing to operate on sp correctly if the lr reg is involved..
2012-08-14T10:27:01 < cjbaird> bing! .. yep, the new TNT-compiled with _atrib_ naked reset_handler() hacks makes it werk.
2012-08-14T10:28:59 < zippe> cjbaird: yes, just your reset handler
2012-08-14T10:29:19 < zippe> And dongs, you're a complete retard.  v7m is designed to work just fine with reset handlers written in C.
2012-08-14T10:29:51 < zippe> You don't even need the decorations on your reset handler if you've laid the stack out in your vector table correctly.
2012-08-14T10:30:15 < dongs> why the hell are tehre liek 200 different can transceivers
2012-08-14T10:30:19 < dongs> are they all same pinout?

2012-08-14T10:30:43 < cjbaird> That's what made me suspicious with the code that TNT produced..
2012-08-14T10:31:00 < zippe> cjbaird: yes, but where is the stack?
2012-08-14T10:31:26 < zippe> And does the bss clear it?
2012-08-14T10:31:48 < zippe> if it spills something and then you zero it, that might get uglty

2012-08-14T10:32:09 < dongs> zyp, which one did you use
2012-08-14T10:32:38 < zyp> cheapest I could find that would run on 3.3V
2012-08-14T10:32:41 < dongs> lol
2012-08-14T10:32:52 < zyp> most require more
2012-08-14T10:32:57 < dongs> so  basically any 3.3V can transceiver works?
2012-08-14T10:33:16 < zyp> unless the specs says otherwise

2012-08-14T10:37:04 < dongs> and did you acutally confirm it worked
2012-08-14T10:37:06 < Thorn> link to datasheet
2012-08-14T10:37:11 < dongs> http://www.ti.com/lit/ds/symlink/sn65hvd232.pdf
2012-08-14T10:37:13 < zyp> I'll have to look it up
2012-08-14T10:37:37 < Thorn> driver & receiver
2012-08-14T10:37:49 < zyp> yeah
2012-08-14T10:38:07 < zyp> looks like same pinout as all the other ones I've looked at
2012-08-14T10:38:37 < zyp> pretty much every can transceiver in SO-8 has that pinout, except that pins 5 and 8 vary a bit
2012-08-14T10:39:00 < dongs> pin5 is some kinda half voltage shit
2012-08-14T10:39:03 < dongs> just dont use it i guess.
2012-08-14T10:40:09 < zyp> ah, right, I'm using the one you linked to
2012-08-14T10:40:10 < zyp> SN65HVD232QD

2012-08-14T10:42:18 < dongs> ok, cool
2012-08-14T10:42:21 < dongs> yeah thats waht i was gonna do
2012-08-14T10:42:38 < Thorn> looks like CAN implementations have way more builtin reliability features than rs-485 ones
2012-08-14T10:43:19 < zyp> I chose the transceiver after I ordered the board, that's why I connected pin8 even though it's NC for that particular transceiver
2012-08-14T10:43:38 < dongs> isnt it enable pin on others
2012-08-14T10:43:50 < dongs> active low or someshit
2012-08-14T10:43:54 < zyp> yes
2012-08-14T10:44:05 < zyp> where you can put a resistor to select strength
2012-08-14T10:44:21 < dongs> well wahtever that shit's goin to ground
2012-08-14T10:44:25 < zyp> :p
2012-08-14T10:45:04 < zyp> Thorn, I'm of the impression that CAN is newer, and it's intended for shit where reliability is required
2012-08-14T10:45:30 < zyp> so it makes sense
2012-08-14T10:45:42 < BrainDamage> it is newer and it is built for reliability
2012-08-14T10:45:51 < Thorn> spacewire is even more cool but no cheap or widely available chips exist
2012-08-14T10:46:06 < BrainDamage> can was invented esp for the ridicolously noisy system that are automotive networks
2012-08-14T10:46:56 < BrainDamage> I only wish the phy was as cheap as rs-485 ones :/
2012-08-14T10:48:46 < dongs> rs485 shit is usually bought in dip and put in sockets
2012-08-14T10:48:50 < dongs> as taht shit burns out often.
2012-08-14T10:48:54 < dongs> so teh cost issues are irrelevant
2012-08-14T10:49:04 < dongs> the problem is that some trash insists on talkign rs485
2012-08-14T10:49:07 < dongs> so you dont have a choice

2012-08-14T11:03:46 < dongs> so wtf? I dont need pullup on DP for F4?
2012-08-14T11:03:48 < dongs> for USB
2012-08-14T11:06:42 < zyp> no, it's built in
2012-08-14T11:06:43 < Thorn> it's otg, so it should have it built in
2012-08-14T11:06:48 < dongs> intersting
2012-08-14T11:06:55 < dongs> maybe ill hookup ID pin just for lulz.
2012-08-14T11:06:59 < Thorn> as it needs to connect/disconnect it based on mode
2012-08-14T11:07:00 < dongs> so i can dick aroudn with host stuff
2012-08-14T11:08:19 < zyp> I'd do it if I redid my board, since pin is free anyway and it routes along the other three usb signals
2012-08-14T11:08:41 < Thorn> you'd need an AB socket though
2012-08-14T11:08:43 < dongs> oh hm its a non-remappable pin
2012-08-14T11:08:49 < dongs> im using it for usart
2012-08-14T11:09:02 < zyp> Thorn, nah, no point if you can't provide vbus anyway
2012-08-14T11:09:43 < dongs> ok, not connectingf it then.
2012-08-14T11:10:01 < zyp> and adding shit to provide vbus starts getting unnecessary expensive if you're not going to use it anyway
2012-08-14T11:11:39 < Thorn> how do you design electronics to withstand ~10^5G? http://en.wikipedia.org/wiki/Krasnopol_%28Weapon%29
2012-08-14T11:13:38 < dongs> cute
2012-08-14T11:15:36 < Thorn> NASA also had failed mars impact probes which were supposed to hit mars with 60K G and then drill(!) the soil
2012-08-14T11:15:49 < zyp> Thorn, where did you get 10^5G from?
2012-08-14T11:16:29 < Thorn> ah wait. more like 10^4 I think
2012-08-14T11:16:42 < Thorn> not too sure though
2012-08-14T11:16:43 < zyp> still sounds high to me
2012-08-14T11:16:43 < dongs> fun fact: I had a gopro fall down flat on its lens into concrete from ~100meters up. the BGA main SoC tore itself off the pcb, even though it was sandwiched between 2 pieces of aluminum heatsink
2012-08-14T11:17:59 < Thorn> zyp: one source says 15,500G (not sure for what caliber)
2012-08-14T11:18:12 < Thorn> although it's all internet quality information
2012-08-14T11:18:17 < zyp> hmm
2012-08-14T11:18:43 < dongs> i think most mems devices are rated at liek 10k G non-operating shock
2012-08-14T11:18:43 < zyp> well, it kind of makes sense anyway
2012-08-14T11:18:54 < zyp> I was just too caught up in thinking about missiles instead
2012-08-14T11:19:48 < zyp> rocket engines with a few seconds of burn time obviously doesn
2012-08-14T11:19:59 < zyp> 't need the same acceleration as cannon launched shit
2012-08-14T11:21:27 < zyp> when I was in space tech school, we launched a sounding rocket, based on a CRV7 rocket engine
2012-08-14T11:22:13 < zyp> we did sensors for the payload, I did an accelerometer
2012-08-14T11:22:22 < zyp> measured around 70g peak
2012-08-14T11:24:12 < Thorn> more interesting uses of electronics: when underground nuclear tests were conducted, they apparently used a 1m long piece of steel, sensors at one end, control electronics on the other, with cables going up. this thing was lowered into the shaft onto the "device" until physical contact. and it did pass useful data during the explosion.

2012-08-14T19:17:34 < zippe> When you say "normal gcc vector", what you mean is the STL that comes with newlib?

2012-08-14T19:19:22 < jpa-> (i mean libstdc++)
2012-08-14T19:19:47 < zippe> glibc++ is what gets packaged with newlib, yes
2012-08-14T19:20:09 < zippe> It is not "nice" or "small"

2012-08-14T20:02:06 < Thorn> calling usb experts concerning interrupt IN transfers
2012-08-14T20:02:35 < Thorn> do they happen "automagically" or does a device driver need to poll the device?
2012-08-14T20:09:03 < zippe> The hardware polls the device
2012-08-14T20:09:18 < zippe> USB is all master/slave, devices can never send anything; they are always pollewd
2012-08-14T20:09:33 < Thorn> right
2012-08-14T20:09:44 < zippe> interrupt endpoints are the same deal
2012-08-14T20:09:50 <+izua> Thorn: not sure if helping, i know that data sent from clients to the host isn't sent, but buffered untill the host polls for it, and it keeps polling in a pretty specific fashion
2012-08-14T20:09:51 < zippe> They're just dataless
2012-08-14T20:11:05 < Thorn> but if I'm not mistaken someone in this channel once said that polling for interrupt transfers is done by device drivers. so my question was if it's hardware / low level os drivers / whatever or the device driver
2012-08-14T20:12:22 < Thorn> (for reference, you can see here that interrupt transfers are host initiated http://www.beyondlogic.org/usbnutshell/usb4.shtml#Interrupt )
2012-08-14T20:14:28 < Thorn> and the polling rate is spcified in the endpoint descriptor btw
2012-08-14T20:14:49 < zyp> how it's done obviously depends on the host implementation
2012-08-14T20:15:21 < zyp> but I would imagine most host controllers does the job of polling automatically
2012-08-14T20:19:04 < Thorn> linux drivers need to set polling interval http://www.mail-archive.com/linux-usb-devel@lists.sourceforge.net/msg15759.html
2012-08-14T20:30:20 < Thorn> I wonder how stm32 OTG controllers do it btw
2012-08-14T20:47:30 < zyp> hmm
2012-08-14T20:48:13 < zyp> looks like it has two transfer queues, one for periodic transfers (interrupt, isochronous) and one for nonperiodic transfers (control, bulk)

2012-08-15T13:27:12 < Thorn> so f4 has two usb controllers, FS and HS
2012-08-15T13:27:33 < Thorn> the HS one has 5 pipes in device mode while the FS one has 3
2012-08-15T13:27:52 < Thorn> and it has a builtin FS PHY
2012-08-15T13:28:08 < Thorn> so why the FS controller?
2012-08-15T13:29:15 < zyp> because then you have two.
2012-08-15T13:30:20 < Thorn> you can use them at the same time?
2012-08-15T13:30:40 < dongs> i heard you like usb
2012-08-15T13:30:56 < dongs> so i connected ur fs controlelr to ur hs controller so you could usb while you usb.
2012-08-15T13:32:55 < Laurenceb_> is there CDC code for F4 usb that doesnt involve chibios?
2012-08-15T13:33:37 < Thorn> um1021 6.7.5
2012-08-15T13:33:38 < dongs> niggyos
2012-08-15T13:33:52 < dongs> what are you doign with USB+CDC+F4?
2012-08-15T13:35:37 < zyp> Thorn, of course you can, why wouldn't you?
2012-08-15T13:36:06 < zyp> Laurenceb_, I believe libopencm3 also have some
2012-08-15T13:36:17 < Laurenceb_> oh yeah
2012-08-15T13:36:21 < Laurenceb_> think i was that
2012-08-15T13:36:26 < Laurenceb_> *saw
2012-08-15T13:36:27 < Thorn> for 10e6 reasons, e.g. on f103 usb shares memory with CAN so you can't use them at the same time
2012-08-15T13:36:49 < zyp> f103 use a completely different controller
2012-08-15T13:36:51 < Laurenceb_> but i cant get libopencm3 to compile properly with codesourcery
2012-08-15T13:37:19 < Thorn> sure. it was an example
2012-08-15T13:37:45 < dongs> Laurenceb_: amazing, it fails to compile wiht gcc
2012-08-15T13:37:48 < dongs> and it w as made for gcc only
2012-08-15T13:37:56 < zyp> Thorn, but that's ok, then you can either use usb or can, makes sens
2012-08-15T13:38:00 < dongs> i need to do cdc on  f103 again (:
2012-08-15T13:38:14 < zyp> Thorn, but being able to use either usb or usb doesn't really make sense, does it?
2012-08-15T13:38:20 < dongs> haha
2012-08-15T13:39:10 < zyp> usb and can in f103 shares both the same pins, so you can only hook up one at a time anyway
2012-08-15T13:39:12 < Thorn> for a usb to can interface, as an example, the former does, the latter doesn't
2012-08-15T13:39:18 < dongs> zyp: uh what
2012-08-15T13:39:21 < zyp> OTG_FS and OTG_HS are on completely different pins
2012-08-15T13:39:34 < Thorn> CAN can be remapped to different pins
2012-08-15T13:40:41 < karlp> Laurenceb_: what wasn't compiling for you?
2012-08-15T13:40:51 < Laurenceb_> stack index stuff
2012-08-15T13:40:58 < dongs> Thorn: yea lol, to extosc pins
2012-08-15T13:41:03 < dongs> Thorn: thus preventing you from using USB
2012-08-15T13:41:08 < dongs> since you cant run that off intrc
2012-08-15T13:41:12 < Laurenceb_> i thought i managed to hack the linker script make it work
2012-08-15T13:41:27 < dongs> pretty clever
2012-08-15T13:41:28 < Laurenceb_> but the code was doing mad stuff in the reset handler
2012-08-15T13:41:43 < cjbaird> The Daily Muffin: http://i.imgur.com/0QNXy.jpg  (apple + rum sultana)
2012-08-15T13:41:46 < dongs> Laurenceb_: someone was having exactly same problem recently
2012-08-15T13:41:47 < Laurenceb_> i could ask fnobel/hallam for advice
2012-08-15T13:41:55 < Laurenceb_> know them from uni
2012-08-15T13:42:18 < Thorn> in f103v, there're 2 remaps for CAN that do not conflict with the oscillator
2012-08-15T13:42:25 < Laurenceb_> they seem to be doing most of the libopencm3 dev these days
2012-08-15T13:43:29 < dongs> libopencm3 will never be taken seriously until it supports more than gcc
2012-08-15T13:43:31 < dongs> and stops using gccisms
2012-08-15T13:43:40 < dongs> until then its just another opensores project with no future

2012-08-15T13:53:40 < dongs> tasking is some lame IDE shit from altium dudes
2012-08-15T13:53:48 < Thorn> freertos c-m3 tasking port, usb otg examples support tasking
2012-08-15T13:53:53 < dongs> must be that then
2012-08-15T13:53:57 < Thorn> thought so
2012-08-15T13:54:09 < Thorn> thanks
2012-08-15T13:56:00 < Thorn> so basically if you want compatibility, do not use f103 usb because it's incompatible with anything else?

2012-08-15T17:19:04 < zyp> Laurenceb_, yes, it has circuits for vbus output and everything

2012-08-15T17:24:01 < Laurenceb_> https://www.das-labor.org/trac/browser/microcontroller/src-stm32f4xx/serialUSB/usbd_cdc_vcp.c
2012-08-15T17:24:21 < Laurenceb_> i can use the functions that have been added there to use VCP for debug output
2012-08-15T17:24:35 < Laurenceb_>  - they added VCP_send_str etc
2012-08-15T17:25:12 < Laurenceb_> but all the data will be echoes on USART
2012-08-15T17:25:20 < Laurenceb_> *echoed
2012-08-15T17:25:50 < Laurenceb_> unless I rewrite the usb code so its proper ACM
2012-08-15T17:26:26 < Laurenceb_> zyp: do you know how ACM differs? VCP doesnt look very complex - an 8 byte control struct gets sent to third endpoint to config the serial
2012-08-15T17:27:00 < zyp> I haven't looked very closely
2012-08-15T17:27:24 < Laurenceb_> maybe i should read the chibios code

2012-08-15T17:50:57 < Laurenceb_> think ill just use the haxored VCP code
2012-08-15T17:51:17 < Laurenceb_> rather than taking chibios descriptors, as the transport seems slightly different

2012-08-15T17:52:44 < Laurenceb_> the ST VCP code just has bulk in and out, and a control endpoint that gets 8 byte control structs for baud parity etc

2012-08-15T17:52:56 < dongs> thats all there is

2012-08-15T17:53:45 < Laurenceb_> i suspect applying the chibios descriptors to the st code will fail horribly

2012-08-15T17:54:17 < Laurenceb_> then they both talk at once
2012-08-15T17:54:21 < dongs> heh
2012-08-15T17:54:35 < Laurenceb_> i solved the issue by forcing the adc to convert
2012-08-15T17:54:42 < Laurenceb_> then it wont respond until ready
2012-08-15T17:54:56 < dongs> heh
2012-08-15T17:55:05 < dongs> i dont think im gonna be able to do that
2012-08-15T17:55:13 < dongs> acutally maybe
2012-08-15T17:55:16 < dongs> cause I have xclr from baro
2012-08-15T17:55:18 < dongs> on a pin
2012-08-15T17:55:24 < dongs> so i can just reset that fucker and keep it in reset.

2012-08-15T17:59:34 < dongs> so fucking dumb

2012-08-15T18:00:03 < dongs> activate it by making 'screwing' motion?
2012-08-15T18:02:59 < dongs> kinda lame raping BMP at first though but I guess if its connected theres no other way ot shut it up
2012-08-15T18:03:04 < Thorn> they should have made a screw activated screwdriver instead

2012-08-15T22:29:26 < Thorn> so in case of one master and multiple slaves (USB), slaves will receive data for other slaves in case of a hub and will not if there's a switch, no?
2012-08-15T22:31:02 < zyp> this discussion is pretty pointless
2012-08-15T22:31:40 <+izua> are there usb hubs that act like ethernet hubs? aren't usb hubs acting like ethernet switches?
2012-08-15T22:32:26 < zyp> no, both are wrong, usb hubs acts as usb hubs
2012-08-15T22:32:32 <+izua> i know there are usb 'splitter' cables which are small enough that they probably don't have electronics enough, sort of like a T junction, one father slot on one end, one mother slot at the other, and a long cable
2012-08-15T22:32:38 < zyp> which shares some properties with each
2012-08-15T22:32:38 <+izua> and you can chain 'em together
2012-08-15T22:33:22 <+izua> well. a switch would switch packets around. a hub wouldn't. that's the kind of behaviour i'm pointing to
2012-08-15T22:33:43 < Thorn> why the hell can frames are only 8 bytes. I need to send 12
2012-08-15T22:33:49 < zyp> and usb hubs does both depending on the occation
2012-08-15T22:33:56 <+izua> and as far as i know, a usb hub isolates data streams, since you can plug mixed speed devices, and not be limited to the lowest speed.
2012-08-15T22:34:21 <+izua> hmm
2012-08-15T22:34:42 <+izua> i have no idea
2012-08-15T22:35:01 <+izua> but i know my keyboard becomes very slow when i plug in my usbtiny avr programmer and run it
2012-08-15T22:35:54 <+izua> it might be the fact that it's a low speed device, or the fact that it bitbangs data bit by bit, or both..
2012-08-15T22:36:28 <+izua> i have yet to find a decent usb hub

2012-08-15T22:41:26 < zyp> this is taken with the analyzer connected downstream of a hub, to my F4 board
2012-08-15T22:41:41 < zyp> it enumerates as device 14
2012-08-15T22:42:24 < zyp> device 15 is the blackmagic probe, plugged into the same hub, traffic is caused by me starting gdb and connecting to it
2012-08-15T22:42:34 < zyp> it was plugged into the hub before the trace started
2012-08-15T22:43:10 < zyp> also plugged into the hub is the usb analyzer itself, but HS traffic is not visible on FS ports
2012-08-15T22:44:17 < zyp> this demonstrates that one FS device can see traffic to other FS devices
2012-08-15T22:45:05 < zyp> hmm, but not _from_
2012-08-15T22:45:38 < zyp> I didn't capture any IN transfers from device 15
2012-08-15T22:46:27 < Thorn> that's a short enumeration. I've seen >10 requests for my attempt at HID
2012-08-15T22:47:23 < Thorn> including a lot of "get status" requests which it didn't implement
2012-08-15T22:47:57 < zyp> yes, my device is set as vendor specific class, so it doesn't do anything more than assign an address and read the device descriptor
2012-08-15T22:48:37 < zyp> it can't really do much more, it doesn't have any driver for it
2012-08-15T22:48:52 < zyp> it as in the operating system
2012-08-15T22:50:20 < Thorn> looks like a usb analyzer is pretty essential
2012-08-15T22:50:24 < zyp> it doesn't need to do more either, I'm using libusb in my application to select a configuration and communicate directly with bulk endpoints
2012-08-15T22:50:41 < zyp> depends on what you do
2012-08-15T22:51:51 < Thorn> I printf-debugged my usb device, wasn't particularly fun
2012-08-15T22:51:52 < zyp> if you only work with higher layers, using a soft analyzer like wireshark to just capture on the host might be enough
2012-08-15T22:52:44 < zyp> knowing exactly what goes on on the line is nice when writing everything from ground up though

2012-08-15T23:07:32 < zyp> zippe, you don't happen to know why pending data in the TX fifo for IN endpoint 1 may be sent instead of the data sent as the IN response to a control transfer? :p
2012-08-15T23:09:28 < zyp> I've observed behavior that suggests that it's happening, but I haven't had time to isolate and test what is causing it
2012-08-15T23:11:02 < zyp> though, it's probably just my hackish code that is doing something not entirely as intended and hitting some weird quirk
2012-08-15T23:16:59 < zippe> zyp: have you overrun the FIFO?
2012-08-15T23:17:16 < zyp> how?
2012-08-15T23:17:26 < zippe> I know *of* many bugs in the Synopsys RTL, but I have studiously avoided any intimate involvement
2012-08-15T23:18:10 < zippe> zyp: bad FIFO layout configuration, perhaps?
2012-08-15T23:18:23 < zyp> I've double checked that
2012-08-15T23:18:35 < zippe> Ok.  FIFOs are all nice large round number-sized?

2012-08-15T23:27:04 < zyp> fun fact: there is a bunch of registers present in those which is not documented in the stm32 reference manual

2012-08-15T23:58:48 < zyp> so I've heard
--- Day changed Thu Aug 16 2012
2012-08-16T00:02:09 < Thorn> I can't figure out how many controllers thy actuallyhave. the manual has 3 chapters, for device, host and otg
2012-08-16T00:03:06 < zyp> not different modes of the same?
2012-08-16T00:03:46 < Thorn> "On these devices, the USB controller can be configured for device, Host, or OTG operation."
2012-08-16T00:03:58 < Thorn> probably only one
2012-08-16T00:04:43 < Thorn> only one "power on" bit
2012-08-16T00:09:32 < zippe> OTG is "host or device with some goo in the port driver to help switch"
2012-08-16T00:09:46 < zippe> You can synthesise just host, just device, or both with OTG glue
2012-08-16T00:10:25 < Thorn> well nxp has device, host *and* otg modes for some reason
2012-08-16T00:19:25 < zippe> No, that's normal
2012-08-16T00:19:36 < zippe> OTG is just a bunch of arbitration
2012-08-16T00:19:51 < zippe> You can force a mode, or you can let the PHY negotiate and then respect what the PHY tells you to do
2012-08-16T00:20:37 < zippe> Sometimes OTG means that HNP is supported, other times it just means a host and a device block sharing a PHY
2012-08-16T00:21:05 < zippe> FWIW, almost nobody /uses/ HNP
2012-08-16T00:21:25 < Thorn> well those synopsys cores are OTG but can be switched to host-only or device-only, so it's basically the same functionality, but they don't require separate documentation for different modes
2012-08-16T00:24:03 < zyp> oh, it's seperate subchapters in the reference manual

2012-08-16T00:26:44 < zippe> At its heart, it's several techniques for deciding whether to turn on the host or the device controller.
2012-08-16T00:27:36 < zippe> You can either use the host select pin (why there are 5 pins in the mini/micro connectors), or you can implement HNP in the PHY
2012-08-16T00:27:56 < zippe> But this has nothing to do with the MACs.

2012-08-16T00:42:03 < zippe> Yes
2012-08-16T00:42:21 < zippe> If you mean "configurations where a host and device share a phy that does not support HNP"
2012-08-16T00:43:18 < zippe> Though with a GPIO you can make them "OTG"
2012-08-16T00:43:20 < zyp> I'm not sure what I mean
2012-08-16T00:43:28 < zyp> yes, that's just what I was thinking
2012-08-16T00:44:17 < zippe> When you say "controllers supporting both" … you don't build a single "controller" that supports host and device
2012-08-16T00:44:22 < zippe> They are totally different things
2012-08-16T00:44:31 < zippe> So you have an IP block that does USB Host
2012-08-16T00:44:37 < zippe> and a completely separate block that does USB Device
2012-08-16T00:46:18 < zyp> I haven't looked inside any hardware implementations, but I would imagine they have parts in common that don't need to be duplicated
2012-08-16T00:46:46 < zippe> You would be wrong
2012-08-16T00:47:13 < zyp> then what about the FIFO memory in the dwc controllers?
2012-08-16T00:47:20 < zippe> The bits that can be duplicated are called the phy
2012-08-16T00:47:48 < zippe> Feh, RAMs.  Ok, whatever.
2012-08-16T00:48:36 < zippe> Assuming they are actually the same RAM, that's optimising the topside for area's sake

2012-08-16T03:37:24 < LeelooMinai> Any tips on getting C++ on discovery F0 working in eclipse in Windows... I can get C working fine with Codesorcery Lite
2012-08-16T03:37:49 < dongs> why would you ever want to use C++
2012-08-16T03:38:07 < LeelooMinai> dongs, Not helping... :p
2012-08-16T03:38:34 < dongs> i am helping
2012-08-16T03:38:39 < LeelooMinai> Not really...
2012-08-16T03:38:46 < emeb> Because it's hot! It's the language that all the cool kids are using! The language of the future!
2012-08-16T03:39:01 < dongs> i'm allowing you to reconsider your decision to use a retarded language
2012-08-16T03:39:18 < LeelooMinai> You have no idea... I am 10 steps ahead of you

2012-08-16T03:41:19 < dongs> right. so what are you doing that needs C++.
2012-08-16T03:42:34 < LeelooMinai> I'm not here to discuss that - just asked s simple question - you have no answer, fine... but don't derail it into some religious discussion on coding
2012-08-16T03:43:16 < dongs> I'm not derailing into anything. im asking a fucking question thats relevant to your question.
2012-08-16T03:44:23 < LeelooMinai> No it isn't
2012-08-16T03:44:42 < LeelooMinai> My question was about getting C++ working...
2012-08-16T03:44:45 < dongs> I suggest you pay mentor graphics for a support contract if you aren't ready to chat when chatted to
2012-08-16T03:45:08 < LeelooMinai> I suggest you focus on what people ask you, not go into tangent topics
2012-08-16T03:45:15 < dongs> or upgrade to realview/armcc.
2012-08-16T03:46:40 < LeelooMinai> My plan is getting it to work on Juno + some free toolchain like codesorcery - totally open source

2012-08-16T03:49:40 < GargantuaSauce> make sure you use boost, i hear that makes c++ development much easier
2012-08-16T03:51:11 < LeelooMinai> Yes, I intend to use STL too, and maybe I will get Visual Studio working too

2012-08-16T08:16:26 < cjbaird_> Hany many millions has Assange wasted of donated money over a max $1500 fine..
2012-08-16T08:16:39 < dongs> 1500 fine for rape?
2012-08-16T08:16:45 < dongs> i thought he was gonna be in jail fora while for that
2012-08-16T08:19:43 < cjbaird_> He's being hit with a 'sexual miscounduct' charge, not a full-blown sexual assault charge.
2012-08-16T08:19:51 < dongs> oh ok
2012-08-16T08:19:55 < dongs> so whats hte problemr then
2012-08-16T08:21:14 < cjbaird_> This is a nutcase who madly tweeted that he was about to be set to Gitmo when Customs had him wait for 15 minutes for a new passport the last time he was in Australia..
2012-08-16T08:22:28 < dongs> sounds like he's into trolling
2012-08-16T08:23:03 < Oldboy> You don't threaten to invade another nations embassy over a 'sexual misconduct' charge
2012-08-16T08:23:21 < Oldboy> this is about wikileaks and extraditing Assange to America
2012-08-16T08:23:25 < cjbaird_> I can vouch he's a schizophrenic.
2012-08-16T08:23:58 < cjbaird_> "threaten to invade another nations embassy" is a very spun description on the situation.
2012-08-16T08:25:38 < dongs> why ecuador anyway

2012-08-16T08:28:30 < cjbaird_> I wonder if Assange will do the same thing with Ecuador like he did with Sweden-- start of by saying how great the place will be... and then go nutso when the cops go after him for breaking laws, and getting his followers to parrot along..

2012-08-16T08:32:37 < zippe> cjbaird_: actually, no
2012-08-16T08:33:00 < zippe> cjbaird_: this has nothing to do with the "questioning", it has to do with Sweden's extradition treaty with the USA
2012-08-16T08:33:30 < zippe> cjbaird_: and the Swedish government's general status as a US puppet regime

2012-08-16T08:36:16 < cjbaird_> Show me where "Sweden is a puppet regime", outside of Assange's blatherings.
2012-08-16T08:36:21 < zippe> Tell me something here.  What do you know about Mark Newton?
2012-08-16T08:36:52 < dongs>  who

2012-08-16T08:39:59 < zippe> In general, it's amusing watching diplomacy catch up with the interwebs
2012-08-16T08:40:53 < zippe> … and poking fun at sour old cunts like you that won't let go of their preconceptions.
2012-08-16T08:40:58 < cjbaird_> And yet, Al-Qaeda suspects like Munir Awad have been arrested in Sweden, and somehow stayed put in the country/
2012-08-16T08:41:30 < dongs> but alqueeda is less nutty than this guy
2012-08-16T08:41:39 < dongs> didnt he post some srs shit about america.
2012-08-16T08:41:40 < zippe> Yes, Assange is a jerk.  Yes, he's a fucking idiot for sticking his dick into the honeytrap.  But it's rarely that simple.
2012-08-16T08:41:50 < zippe> Who gives a shit about AQ?
2012-08-16T08:42:01 < LeelooMinai> http://i.imgur.com/Ej3MD.png <- any idea why the address is offset by 1 somehow in the interrrupt table?
2012-08-16T08:42:12 < zippe> What have they done lately that would make extraditing any of them worth the effort to lift the phone.
2012-08-16T08:42:29 < dongs> LeelooMinai: by design

2012-08-16T08:44:01 < LeelooMinai> Hmm...
2012-08-16T08:44:15 < zippe> Hint: the address is not offset.
2012-08-16T08:44:30 < zippe> Instructions are always 16-bit aligned.  The low bit is not part of the address.
2012-08-16T08:44:32 < LeelooMinai> Isn't F0 Armv6?
2012-08-16T08:44:46 < LeelooMinai> THis pdf is about ARMv&-M architecture

2012-08-16T08:46:35 < LeelooMinai> Well, you could guess it from the screenshot:)
2012-08-16T08:46:43 < zippe> Why would I look at your screenshot?
2012-08-16T08:47:07 < LeelooMinai> I thought I gave link to screenshot with my question...
2012-08-16T08:47:16 < zippe> Yes, but it wasn't necessary.
2012-08-16T08:47:53 < LeelooMinai> True, still... I cannot see over your shoulder if you read my screenshot or not:)
2012-08-16T08:49:23 < zippe> Assuming you are looking at DDI0419C, you want §A2-36
2012-08-16T08:50:38 < zippe> It is opaque, but you will be better for understanding it.
2012-08-16T08:50:40 < zippe> Honest.
2012-08-16T08:52:16 < LeelooMinai> Well, I got there because my SysTick_Handler does not get executed (I think - the breakpoint does not trip)... and I noticed those weird addresses in the table - thought it was the reason... I guess not

2012-08-16T14:44:17 < cjbaird_> I've spent the evening at a Medical Centre, after splitting my head open at the local mall (/someone/ is gonna have a lot of OH&S paperwork to do tomorrow..) A Pedestrian diversion lead me walking into a head-height fire sprinkler. Bloooooood everywhere. Sticking plaster on (disinfected) head. Antibiotics. Can't have alcohol for 24 hours. :/
2012-08-16T14:44:29 < cjbaird_> I'd just bought a 1.125l bottle of Rum, too.
2012-08-16T14:45:05 < cjbaird_> If I get an MRSA infection, and they have to amputate my head, I can sue! :D
2012-08-16T14:45:43 < dongs> awesome blog dude
2012-08-16T14:45:50 < dongs> please tweet some pics
2012-08-16T14:46:44 < cjbaird_> All my friends here can send me alcohol as get-well presents.
2012-08-16T14:48:11 < cjbaird_> But none of that Sake shit, dongs.
2012-08-16T14:54:59 < zyp> didn't your head come with eyes? you should be able to see shit if it's in head height
2012-08-16T14:55:56 < dongs> zyp: http://www.youtube.com/watch?v=TvJg6dGMGJA this guy couldnt
2012-08-16T14:59:03 < Tectu> good job, cjbaird_
2012-08-16T14:59:09 < Tectu> hope you feel better soon
2012-08-16T14:59:12 < zyp> dongs, nice
2012-08-16T14:59:16 < dongs> he was raged at assange
2012-08-16T15:03:46 < cjbaird_> zyp: years in mspaint: http://i.imgur.com/jNnsq.png .. the fire sprinklers weren't visible from the side. There was a pedestrian diversion while the mall was repainting the car parking lanes.
2012-08-16T15:06:25 < cjbaird_> Someone will be in the shit for removing the plastic guards around the sprinklers (if they were ever installed..)
2012-08-16T15:10:00 < Tectu> cjbaird_, pretty good paint work!
2012-08-16T15:11:17 < cjbaird_> Learnings from my University Geometry coursework went into that.
2012-08-16T15:27:27 < Tectu> cjbaird_, looks like the money was spend in a good way then

2012-08-16T19:12:02 < zyp> aren't the functions documented?

2012-08-16T19:12:38 < dongs> but ctrlpwm shit doesnt take individual channels

2012-08-16T21:38:58 < zyp> compilers doesn't need to do any magic, so interrupt handlers can be normal functions

2012-08-17T03:06:22 <+izua> do they always happen?
2012-08-17T03:06:49 <+izua> maybe your programmer/debugger is blocking the hex. i had something like this with a weird avr programmer, before avrdude
2012-08-17T03:07:25 < LeelooMinai> Well, I just found out that fireing up process explorer that watches for file changes eliminates it - weird - I guess it introduces some delay and make works
2012-08-17T03:08:03 < LeelooMinai> I guess something there happens too fast during normal build
2012-08-17T03:09:19 < LeelooMinai> Hmm... I don't use parallelism option for make... so not sure what's going on here
2012-08-17T03:09:38 < LeelooMinai> googled, but found nothing
2012-08-17T03:10:29 < LeelooMinai> It does not happen only for .hex - it happens sporadically on  .c files too
2012-08-17T03:11:08 < LeelooMinai> It's almost like some temporary file is not removed fast enough (?) or something like that

2012-08-17T07:02:28 < dongs> start chatting
2012-08-17T07:05:03 < Oldboy> LeelooMinai: turn off your antivirus
2012-08-17T07:05:24 < dongs> lol, antivirus on windows desktops
2012-08-17T07:05:26 < dongs> people still use that?
2012-08-17T07:05:34 < LeelooMinai> Yes, ;like I didn't do that as first thing...:p
2012-08-17T07:05:50 < dongs> i saw avr-gcc doing similar trash
2012-08-17T07:05:55 < dongs> running make quickly would f ail some files
2012-08-17T07:06:01 < dongs> but manually copypasting exactly same gcc build line =- ok
2012-08-17T07:06:09 < zippe> It has to do with the stupid async share mode behaviour
2012-08-17T07:06:11 < dongs> sounds like GNU/failure
2012-08-17T07:06:24 < zippe> When the compiler closes the file and releases the lock, it doesn't propagate instantly.
2012-08-17T07:06:26 < LeelooMinai> Hmm... that's why spying on file access made it work - introduced some delay I gueess
2012-08-17T07:06:31 < Oldboy> zippe: ? what is async share ?
2012-08-17T07:06:51 < zippe> Oldboy: when the compiler opens the output file, the open is unshared
2012-08-17T07:07:21 < zippe> i.e. the posix layer sees O_CREAT | O_EXCL and that translates into SHARE_NONE or whatever the NT sharing mode is (it's been 10+ years since I really cared)
2012-08-17T07:07:41 < zippe> When the file is closed, the lock doesn't go away instantly because windows is not smrt
2012-08-17T07:08:12 < zippe> so if the next tool in the workflow tries to open it, even though it's been closed, the SHARE_NONE is still in place.
2012-08-17T07:08:37 < Oldboy> why would you open exclusive ?
2012-08-17T07:08:39 < zippe> On a posix system, locking is tied closely to the descriptor lifecycle, so as soon as the descriptor is closed the file is free to open again
2012-08-17T07:08:53 < zippe> Oldboy: because it doesn't make sense any other way
2012-08-17T07:09:25 < zippe> On a real posix system, that's a safety technique that lets you detect e.g. a bad parallel build that has two compiler instances trying to generate the same object file.
2012-08-17T07:09:44 < Oldboy> ah
2012-08-17T07:09:51 < zippe> And it'd work that way on Windows too.
2012-08-17T07:10:15 < zippe> But because the tools are written for the posix universe, their expectations don't hold on Redmond's VMS clone.
2012-08-17T07:10:40 < Oldboy> isn't Windows posix compliant since NT ?
2012-08-17T07:10:47 < zippe> *bwahahaha*
2012-08-17T07:10:48 < zippe> No
2012-08-17T07:11:16 < dongs> vsutdio has been doing parallel builds on multiprocessor machines for >years<.
2012-08-17T07:11:27 < dongs> I'd gather probably longer htan gcc / makefile faggots figured out how to add -j to their shit.
2012-08-17T07:11:35 < dongs> and it doenst break.
2012-08-17T07:11:51 < zippe> dongs: I was doing parallel makes on a 6-core multimax back in the win 3.1 days
2012-08-17T07:11:54 < zippe> So sorry, but no.
2012-08-17T07:11:54 < dongs> i'd say 100% toolchain / environment problem
2012-08-17T07:12:03 < zippe> dongs: environment = windows, so yes
2012-08-17T07:12:05 < LeelooMinai> Damn, this channel is not opinionated at all:)

2012-08-17T09:13:58 < zippe> jpa-: it's not responding to me 8(
2012-08-17T09:14:00 < dongs> any way to run stuff at 72MHz off HSI?
2012-08-17T09:14:07 < dongs> F1
2012-08-17T09:14:25 < dongs> i think default SystemInit() shit falls back to some retarded shit when its on HSI
2012-08-17T09:14:30 < dongs> like 24mhz or somethign
2012-08-17T09:14:35 < Tectu> dongs, so it's no "fake"?
2012-08-17T09:14:38 < zippe> dongs: yes, you can drive the PLL from the HSI

2012-08-17T09:49:21 < zippe> uthash also has a dynamic array
2012-08-17T09:49:39 < zippe> But that has no indexing, unless you treat it as a single hash buket

2012-08-17T12:42:01 < zyp> yes, it says that you'll get HSI/2
2012-08-17T12:42:26 < zyp> so you just configure the PLL as you would if you were using HSE with a 4MHz crystal
2012-08-17T12:42:41 < dongs> shit, thats >hard<.
2012-08-17T12:42:56 < dongs> why the fuck isnt there a excel shit for f103 like there is for F2/f4
2012-08-17T12:43:10 < dongs> system_stm32f10x.c is fucking giant
2012-08-17T12:45:53 < dongs> so noramlly 8mhz is hse * 9 = 72,m so all i ened to do is hsi/2*18 = 72?
2012-08-17T12:46:07 < dongs> but pll multuiplier is only goes upt o16
2012-08-17T12:47:41 < zyp> ah, then you're out of luck
2012-08-17T12:47:45 < dongs> really?
2012-08-17T12:47:56 < dongs> but some poles claim its possible
2012-08-17T12:48:09 < dongs> http://www.mikroe.com/forum/viewtopic.php?f=189&t=48678
2012-08-17T12:49:12 < zyp> he writes HSE

2012-08-17T12:49:50 < dongs> 'internal, 8mhz hse', sounds like just a typo no
2012-08-17T12:50:39 < dongs> Here is the setup code to use the internal 8MHz clock – but with the internal clock, we are only able to get a max frequency of 36MHz.
2012-08-17T12:50:42 < dongs> hmml
2012-08-17T12:51:06 < dongs> rage.
2012-08-17T12:51:12 < zyp> anyway, if it's not possible to run a multiplication factor of more than 16, you can't get more than 64 MHz on HSI
2012-08-17T12:51:27 < dongs> theres only that multiplier, right?
2012-08-17T12:51:45 < zyp> seems so
2012-08-17T12:52:04 < dongs> sucketh
2012-08-17T12:52:51 < zyp> F4 is a bit more complex, because it has both multipliers and dividers, so you always divide down the input to 1-2 MHz before entering the multiplier
2012-08-17T12:53:00 < dongs> right
2012-08-17T12:53:28 < zyp> I believe I'm using input / 8 * 336 / 2 to generate 168 MHz on my stuff
2012-08-17T12:54:27 < dongs> well thats pretty fail
2012-08-17T12:55:20 < zyp> well, that's the problem with using F1 :p
2012-08-17T12:55:24 < dongs> noez
2012-08-17T12:55:32 < dongs> the problem with using F1 is F3 is not coming out soon enough

2012-08-17T17:56:38 < zyp> hmm, solved my «EP1 data going to EP0» problem
2012-08-17T17:56:55 <+Steffanx> ...
2012-08-17T17:57:10 < dongs> did you like, start sending data to ep1 instead of ep0?
2012-08-17T17:57:50 < zyp> no, I had a pending transfer on ep1, and then that data got sent on ep0 when trying to do a transfer there
2012-08-17T17:59:20 < zyp> turns out they used the same fifo, and it worked fine until I tried doing one transfer while another was pending
2012-08-17T18:00:05 < zyp> so, yeah, I were dumb and did not specify that ep1 should use txfifo1, so both used txfifo0
2012-08-17T18:00:17 <+Steffanx> Shit happens
2012-08-17T18:00:23 <+Steffanx> Even zyp makes mistakes

2012-08-17T18:01:36 <+Steffanx> Sleep well
2012-08-17T18:01:49 < zyp> writing to the second fifo addr apparently means write to the fifo associated with ep1, not necessarily fifo1

2012-08-18T00:34:38 < Tectu> Steffanx, aah, like the floor before the 14th?
2012-08-18T00:34:42 < Tectu> do i understand this right, Steffanx ?
2012-08-18T00:34:43 <+Steffanx> Yep
2012-08-18T00:34:51 <+Steffanx> Just get it and watch it
2012-08-18T00:34:51 < Tectu> Steffanx, sounds pretty straight forward!
2012-08-18T00:35:00 < Tectu> Steffanx, let's see trail0r first
2012-08-18T00:35:10 <+izua_> heh, the 9th gate was decent back then
2012-08-18T00:35:10 <+Steffanx> No, trailers are useless
2012-08-18T00:35:40 < BrainDamage> if you like primer's convoluted story, make sure to watch "memento"
2012-08-18T00:36:06 <+izua_> ah, that one is awesome
2012-08-18T00:36:36 < Tectu> izua_, i never saw the 9th gate ;)
2012-08-18T00:36:51 < Tectu> BrainDamage, is it like primer?
2012-08-18T00:37:13 < BrainDamage> both have pretty convoluted storyplay
2012-08-18T00:37:14 <+izua_> well, it has a twisted story, but not really techie
2012-08-18T00:37:29 < BrainDamage> but that's the end of resemblance
2012-08-18T00:37:33 <+izua_> you can watch memento with female companionship
2012-08-18T00:38:53 <+Steffanx> Too bad .. tpb is blocked here in the netherlands
2012-08-18T00:39:08 < BrainDamage> here tpb blockage limits to dns blocking
2012-08-18T00:39:17 < BrainDamage> everyone uses direct ip or redirects

2012-08-18T00:39:43 <+izua_> or whatever that was
2012-08-18T00:40:01 < Tectu> BrainDamage, don't see the relation between primer and memento
2012-08-18T00:40:03 <+Steffanx> And some crappy organization also has the power to add new ips/domains
2012-08-18T00:40:21 <+izua_> Tectu: really convoluted story
2012-08-18T00:40:41 < cjbaird> I've been told that 'Back to the Future' is a often-studied script by film students because its an example of a fairly sophisticated plot, yet isn't contraditictory, and totally complete, with no loose ends or such..
2012-08-18T00:41:36 <+Steffanx> And one of the best movies ever

2012-08-18T00:46:34 < cjbaird> motorbike -> motorbike helmet. hay fever -> sneezing.
2012-08-18T00:46:51 <+Steffanx> helmet? sneeze
2012-08-18T00:47:08 < BrainDamage> sneeze to helmet = blind
2012-08-18T00:47:11 <+Steffanx> Just be sure you clean it once in a while
2012-08-18T00:47:19 < cjbaird> ...at 110km/h
2012-08-18T00:47:35 < BrainDamage> I have a sneeze reflext with strong light, when driving even a car can be particularry annoying

2012-08-18T00:47:42 < Tectu> cjbaird, then don't sneeze
2012-08-18T00:48:09 < BrainDamage> Steffanx: how did you get your steffane? sex change surgery?

2012-08-18T00:49:51 <+Steffanx> once a month..
2012-08-18T00:50:13 < BrainDamage> I mean, they are not repetitive from the same user, but the sum of various users randomly arriving to the same idea makes a contigous stream
2012-08-18T00:50:36 < BrainDamage> much like a sum of random uncorrelated events make a gaussian distribution for white noise

2012-08-18T00:51:20 < cjbaird> When I was a teen/early adult, I had a sneeze reflex whenever I got suddenly aroused (Y HELO PUBLICALLY LOGGED CHANNEL) .. Which was a weird thing to have.
2012-08-18T00:52:05 < BrainDamage> considering the amount of shit that Laurenceb and dongs dump here, a boner sneeze is the least of your concerns

2012-08-18T00:56:22 <+Steffanx> wtf what? They released favourite band pussy riot?
2012-08-18T00:56:47 <+izua_> rockbitch is better bro
2012-08-18T00:57:01 < Thorn> my atx psu doesn't want to power my boards with 12V anymore. it turns off when I connect them. it doesn't when I connect a 10R resistor. it does when I connect them with 10R already connected
2012-08-18T00:57:32 < BrainDamage> odd, sounds like the CCM/DCM protection switch
2012-08-18T00:57:32 < Thorn> and they run normally from an unregulated supply
2012-08-18T00:57:48 < BrainDamage> but I don't see why it would do that only from a certain time on
2012-08-18T00:57:58 < BrainDamage> maybe the min load resistor on the psu burned off
2012-08-18T00:57:58 < Thorn> they have dc/dc converters at the input
2012-08-18T00:58:36 < Thorn> if I first attach 10R and then the boards, it shuts down when I connect the boards
2012-08-18T00:59:03 < Thorn> and it doesn't shut doen when I power those same boards from 5V
2012-08-18T00:59:28 < cjbaird> Thorn: I was having a similar problem yesterday (in ##electronics) .. However I was getting shitty load response -- the 5vdc was dropping below 4.0 with only a few watts usage.
2012-08-18T00:59:54 < cjbaird> Tried connecting a spare HHD as a dummy load, didn't improve things.

2012-08-18T01:00:30 < zyp> probably the old kind that regulates on 5V, so it doesn't like too much load on 12V when 5V is unloaded

2012-08-18T01:01:02 < Thorn> that's pretty easy to check (and it is quite old)
2012-08-18T01:01:09 < zyp> I had the same problem and ended up buying a new psu dedicated to testing purposes
2012-08-18T01:01:20 < BrainDamage> Thorn: do you know the ccm/dcm limit too for loading?
2012-08-18T01:02:31 < zyp> http://bin.jvnv.net/f/a8bMt.JPG <- I wanted a power supply capable of actually powering a hovering quadrotor

2012-08-18T01:02:36 < Thorn> my onboard dc/dc's probably operate in DCM, absolutely no idea about the PSU though
2012-08-18T01:02:49 < BrainDamage> pc psu operate in ccm
2012-08-18T01:02:58 < BrainDamage> simply because pc draw a fuckload of power
2012-08-18T01:03:11 < Thorn> not this one, it has no pc attached
2012-08-18T01:03:38 < zyp> http://bin.jvnv.net/f/acJ5t.JPG <- quadrotors also draw a fuckload of power
2012-08-18T01:03:42 < BrainDamage> yes, and old models did shut down when you put them to dcm
2012-08-18T01:03:47 < cjbaird> The raspberry pi cluster here draws about 13-14 watts at full load, and the 20W 5VDC switchmode supply wasn't up to it.
2012-08-18T01:03:49 < zyp> (and the guy who took that picture sucks at using cameras)
2012-08-18T01:04:33 < BrainDamage> some old models avoided dcm mode by adding a resistor at output to ensure min load current
2012-08-18T01:05:10 < BrainDamage> maybe yours had such and it burned out since you said that the problem started happening only recently?
2012-08-18T01:05:15 < cjbaird> Are there any solar-powered UAVs? :) ... I was thinking if it would be possible for one on Mars-- thinking if it were possible on Earth, then Billion-dollar-Science could probably manage it on Mars..
2012-08-18T01:05:29 < cjbaird> ...Venus?
2012-08-18T01:06:05 < BrainDamage> there's some solar powered manned vehicles
2012-08-18T01:06:10 < BrainDamage> but they are super shitty
2012-08-18T01:06:13 < BrainDamage> huuuge wingspan
2012-08-18T01:06:55 < BrainDamage> maybe a zeppelin-like vehicle could work, but the autonomy would be limited by gas leak
2012-08-18T01:07:44 < BrainDamage> fully solar airplane uav should be possible, but they'll need large scale and high costs
2012-08-18T01:08:07 <+izua_> i think nasa built a huge wing 5-10 years ago
2012-08-18T01:08:08 <+izua_> helios?
2012-08-18T01:08:23 <+izua_> it arched like hell and then broke
2012-08-18T01:08:55 <+izua_> or you could build a hot air solar baloon
2012-08-18T01:09:15 < cjbaird> too hippie
2012-08-18T01:09:21 <+izua_> and use some piping to heat water somewhere and move it around?
2012-08-18T01:09:48 < BrainDamage> mmm, maybe double foil to insulate well the balloon
2012-08-18T01:10:00 < BrainDamage> since you'll be very tight on power budget
2012-08-18T01:11:08 < Thorn> no, it still shuts down with 500mA load @ 5V
2012-08-18T01:12:05 < cjbaird> Thorn: I think I'll try downconverting from 12 to 5, and see how much load I can pull then..
2012-08-18T01:19:19 < Thorn> looks like this psu specifically doesn't like my boards. it runs ok with a resistor load
2012-08-18T01:19:34 < Thorn> how's that possible?
2012-08-18T01:19:58 < BrainDamage> inconstant load and too small output capacitance?
2012-08-18T01:19:59 < Thorn> provided they aren't shorted or anything

2012-08-18T14:05:16 < dongs> TitanMKD: url
2012-08-18T14:05:47 < TitanMKD> dongs see here http://bvernoux.free.fr/stm32f4/
2012-08-18T14:06:17 < TitanMKD> it contains also Google Sketchup for board and board + case(SoB)
2012-08-18T14:06:53 <+Steffanx> Too bad that project lacks so many standard components
2012-08-18T14:07:05 < TitanMKD> ?
2012-08-18T14:07:18 <+Steffanx> That eagle skp project
2012-08-18T14:07:46 < dongs> frown, eagle
2012-08-18T14:07:53 < dongs> frown, smd usb
2012-08-18T14:07:57 < TitanMKD> dongs in fact i will finish documentation about it, you have choice of standard Regulator or TI LiPo Charging+Regulator
2012-08-18T14:08:31 < TitanMKD> Steffanx what's not standard ?
2012-08-18T14:08:48 < TitanMKD> i added also png for those which have not Sketchup
2012-08-18T14:08:53 <+Steffanx> Nothing, so it's weird it doesn't have the 3d models of those components
2012-08-18T14:08:58 < dongs> or those on cellphone internet like me
2012-08-18T14:09:00 < TitanMKD> ha yes ;)
2012-08-18T14:09:25 < TitanMKD> Steffanx anyway i use components very new like TI LiPo stuff and they does not exist at all
2012-08-18T14:11:41 < dongs> sureny a 116qfn exists
2012-08-18T14:17:16 < TitanMKD> dongs do you like the board ?
2012-08-18T14:17:39 < TitanMKD> dongs if you think about feature missing it is not too late until i order the PCB tomorrow
2012-08-18T14:28:24 < dongs> does it really break out all the pins
2012-08-18T14:30:51 < TitanMKD> yes
2012-08-18T14:31:01 < TitanMKD> except used pins like USB
2012-08-18T14:32:07 < TitanMKD> dongs exactly 43pins ;)
2012-08-18T14:32:13 < TitanMKD> +SWD Debug
2012-08-18T14:32:38 < TitanMKD> and of course some pins for Power 3V3/GND and VUSB 5V/GND
2012-08-18T14:34:15 < dongs> did you connect OTG_FS_ID or wahtever
2012-08-18T14:34:19 < dongs> so you cna do usb host?
2012-08-18T14:34:29 < TitanMKD> yes ;)
2012-08-18T14:34:45 < TitanMKD> it can act as Device or Host
2012-08-18T14:34:47 < dongs> what about providing vusb
2012-08-18T14:34:55 < dongs> power in host mode

2012-08-18T14:35:15 < TitanMKD> will be more problematic in fact ;)
2012-08-18T14:35:40 < TitanMKD> because i have not planned to add a regulator for 3.3V to 5V
2012-08-18T14:35:47 < TitanMKD> for battery
2012-08-18T14:36:15 < TitanMKD> need to check how to add that because there's really no lot of space on the PCB
2012-08-18T14:36:39 < dongs> whvih lipo does it vchage? 1cell?
2012-08-18T14:36:43 < dongs> chare
2012-08-18T14:36:46 < dongs> charge
2012-08-18T14:37:06 < TitanMKD> yes 1cell
2012-08-18T14:37:20 < TitanMKD> you can also disable charging ;)
2012-08-18T14:37:32 < TitanMKD> on COFF pos
2012-08-18T14:37:39 < TitanMKD> (near USB connector)
2012-08-18T14:37:55 < dongs> I am looking for one or two physically long GPUs, the longer the better. I didn't buy a big case so I could shove low
2012-08-18T14:37:58 < dongs>          profile video cards into it. The tech doesn't matter as long as it or they work. Preference on length is 10.5 inches all
2012-08-18T14:38:01 < dongs>          the way to 13 inches as that the longest card my case can fit.
2012-08-18T14:38:03 < dongs> Its all about how it looks through the case window.
2012-08-18T14:38:04 < dongs> PCB must be black to match my motherboard.
2012-08-18T14:38:14 < TitanMKD> to add 5V boost regulator i need to remove the LD117AS33 optional regulator
2012-08-18T14:39:59 <+Steffanx> wtf dongs ?

2012-08-18T21:33:28 <+izua> i think there was a contraption on hackaday or something, where a guy set up a motion detector and water spray to deter cats
2012-08-18T21:33:39 <+izua> the fun thing is, it provided live action pictures too
2012-08-18T21:34:34 <+izua> found it. fun starts at 5:05 or so https://www.youtube.com/watch?v=uIbkLjjlMV8
2012-08-18T21:41:20 < emeb> hilarious.
2012-08-18T21:41:33 < Thorn> is he actually pisses on his car in that video?
2012-08-18T21:45:57 < qyx_> lol
2012-08-18T22:01:58 < Thorn> what cameras are compatible with DCMI anyway?
2012-08-18T22:02:10 < zyp> DCMI cameras
2012-08-18T22:02:31 < zyp> (just joking)
2012-08-18T22:02:48 < zyp> DCMI is pretty flexible, so it's compatible with a lot of camera sensors
2012-08-18T22:02:57 < Thorn> googling for DCMI only finds stm32 parts
2012-08-18T22:03:16 < Thorn> apparently that's not a standard interface name then
2012-08-18T22:05:42 < zyp> DCMI consists of up to 14 data lines, pixel clock and optional vsync and hsync
2012-08-18T22:06:18 < zyp> it can pretty much be used with any kind of camera spitting out data of that kind

2012-08-18T22:28:20 < emeb> Pretty much any of these would work: https://www.leopardimaging.com/Products.html
2012-08-18T22:29:29 < emeb> If you could get specs for it, this would probably work too: http://www.goldmine-elec-products.com/prodinfo.asp?number=G17609
2012-08-18T22:40:05 <+Steffanx> "however we have no information on hookups, resolution, operating voltage, or any other data for these cameras so we are blowing them out "AS IS" at an extremely low price" ..
2012-08-18T22:40:07 <+Steffanx> aka useless
2012-08-18T22:40:42 <+Steffanx> oh, people already found the specs
2012-08-18T22:41:16 < emeb> linky?
2012-08-18T22:42:16 <+Steffanx> I don't have the specs, i only have some forum post about someone claiming it's easy to find :)
2012-08-18T22:42:25 < emeb> talk is cheap
2012-08-18T22:42:41 < emeb> URLs count more
2012-08-18T22:42:55 <+Steffanx> I know
2012-08-18T22:43:53 <+Steffanx> They even sell it for 1$ ..
2012-08-18T22:44:43 < BrainDamage> check this seller instead: http://stores.ebay.com/electronics-lee/_i.html?_fsub=1858785013
2012-08-18T22:45:02 < BrainDamage> the prices are slightly higher, but every cam has a datasheet link
2012-08-18T22:45:08 < emeb> better - pay $8 for more pixels and good data.
2012-08-18T22:45:16 <+Steffanx> ofcourse
2012-08-18T22:45:43 < emeb> the 0.3Mpx one for $6 looks good.
2012-08-18T22:48:12 < emeb> hmm - funky supply voltages.
2012-08-18T22:49:55 <+izua> neat, and there's no common range for all 5 of them
2012-08-18T22:50:44 < emeb> plus the digital I/O isn't 3V3, so crazy level shifters needed for interfacing.
2012-08-18T22:53:19 <+Steffanx> The one for 7 something is better
2012-08-18T22:53:25 <+Steffanx> 7.99
2012-08-18T22:53:39 <+Steffanx> 1.5 + 3.3V
2012-08-18T22:53:51 < emeb> yep.
2012-08-18T22:54:07 <+Steffanx> *and that 1.5V = internal regulator stuff
2012-08-18T22:54:19 < emeb> 60fps VGA
2012-08-18T22:54:56 < qyx_> http://www.ebay.com/itm/2-Mega-CMOS-camera-module-MT9D112-PLCC24-/280910874256?pt=BI_Electrical_Equipment_Tools&hash=item416797c690
2012-08-18T22:54:59 < qyx_> this one looks great
2012-08-18T22:55:35 <+Steffanx> Why modules that can output jpeg are so expensive? :(
2012-08-18T22:56:41 < zyp> because they contain a jpeg encoder
2012-08-18T22:57:05 <+Steffanx> Ofcourse, but still ? mass production
2012-08-18T22:58:26 < emeb> qyx_: except for the funky supplies & I/O standards.
2012-08-18T22:59:10 < BrainDamage> the IO might not be too bad if it falls within tollerances
2012-08-18T22:59:34 <+Steffanx> IF ....
2012-08-18T23:00:25 < BrainDamage> checking is an exercise left to the reader :p
2012-08-18T23:00:55 < qyx_> hm, everything except io can be 2.8V
2012-08-18T23:01:04 < qyx_> *except core
2012-08-18T23:01:43 < qyx_> and in plcc24 jpeg drawing there are only avdd, dvdd and vdd_io

2012-08-19T00:26:33 < Tectu> have you guys seen this?   http://dmitry.co/index.php?p=./04.Thoughts/08.%20uM0
2012-08-19T00:29:40 < emeb> Right up there with the guy who emulated a full linux system on an AVR
2012-08-19T00:29:45 < zyp> same guy
2012-08-19T00:29:58 < emeb> figures
2012-08-19T00:30:04 < Tectu> emeb, that's the same guy
2012-08-19T00:30:55 < emeb> interesting hobby he's got there - doing difficult but ultimately useless things.
2012-08-19T00:31:17 < Thorn> precisely
2012-08-19T00:31:26 < emeb> kinda like a lot of hobbies in that regard I suppose.
2012-08-19T00:31:34 < Thorn> a free cortex core would be so much better
2012-08-19T00:31:51 < emeb> what do you mean?
2012-08-19T00:32:32 < Thorn> something that can be synthesized
2012-08-19T00:32:49 < Tectu> Thorn, not sure if i understad you correctly
2012-08-19T00:32:58 < emeb> I guess ARM lawyers would be all over your ass if you did that.
2012-08-19T00:33:27 < emeb> whereas a software emulator is not on their radar.
2012-08-19T00:34:07 < Tectu> izua, ping
2012-08-19T00:34:12 < Thorn> can an ISA be patented?

2012-08-19T00:35:57 < emeb> Thorn: pretty sure others have tried to release open source VHDL designs for ARM-like processors and have had to retract them after getting cease & desist letters.
2012-08-19T00:36:41 < Thorn> what were they threatened with and on what basis?
2012-08-19T00:36:50 <+izua> a softcore arm emulator would be nice
2012-08-19T00:37:03 <+izua> like, crappy vhdl cpu, now with thumb mode support
2012-08-19T00:37:13 <+izua> tectu, hello
2012-08-19T00:37:17 < emeb> A couple of University-based projects a few years ago. Don't remember the grim details.
2012-08-19T00:37:22 < Thorn> crappy ones do exist
2012-08-19T00:37:25 < Tectu> izua, did watch the rented movie
2012-08-19T00:37:41 <+izua> you could have all the arm IS and extra stuff?
2012-08-19T00:37:49 <+izua> would that be against it? or having an ARM-like machine
2012-08-19T00:37:52 <+izua> Tectu: and?
2012-08-19T00:38:08 < emeb> Yeah - looks like a long-dead one on Opencores.
2012-08-19T00:38:12 < Tectu> izua, have to watch it again
2012-08-19T00:38:14 < Tectu> izua, :D
2012-08-19T00:38:49 <+izua> aah, yes. that's the fun of it, if you don't read spoilers first :P
2012-08-19T00:39:00 < Tectu> izua, indeed
2012-08-19T00:39:07 < Tectu> izua, as i said, i just linked the spoiler, i didn't read it ;)
2012-08-19T00:39:30 < emeb> See here: http://www.design-reuse.com/news/980/swedish-students-weigh-step-arm7-clone.html
2012-08-19T00:40:33 < Tectu> izua, also hard to understand for me. I mean hard what they speak, not the content. The speaking is not that "clear"
2012-08-19T00:40:43 < Tectu> when english is not your first language
2012-08-19T00:41:09 <+izua> uh, you can get captions i guess
2012-08-19T00:41:47 < Tectu> izua, just one question: the box, the time flows within the same speed, but backwards, right? that's all, no instant jump?
2012-08-19T00:42:01 < zyp> Tectu, are you from some part of the world that dubs everything?
2012-08-19T00:42:04 <+izua> "In the past, ARM is has discouraged open-source enthusiasts seeking to clone ARM cores"
2012-08-19T00:42:13 < Tectu> zyp, no, but switzerland.
2012-08-19T00:42:26 <+izua> linux people should be more like "herp derp let us make us hardware to run our linux"
2012-08-19T00:42:38 < zyp> Tectu, and you still have problems with english?
2012-08-19T00:42:41 < Thorn> so, it's not optimized, even no pipeline, and ARM still takes interest?
2012-08-19T00:42:42 <+izua> if there was no linux and foss, there would be no android, and no arm ><
2012-08-19T00:43:08 < Tectu> zyp, i don't all holywood movies are easy to understand. I understand it like my first language. but that movie does have strange acents. ask izua
2012-08-19T00:43:28 <+izua> Tectu: i'm not exactly sure. i don't think time flows around the box, it just creates a clone of sorts during the time one of you is "out" and the other comes "in"
2012-08-19T00:43:34 < zyp> izua, I hear both iphones and winphones are also based on arm
2012-08-19T00:43:49 <+izua> no foss, no iWare
2012-08-19T00:44:06 <+izua> well, it's not like they're 100% linux code, but still..
2012-08-19T00:44:28 < Tectu> izua, so I am not the only one who dosen't understand it correctly the first time?
2012-08-19T00:44:32 < zyp> also, your arguments doesn't make sense any way
2012-08-19T00:44:55 <+izua> m-hm, i guess
2012-08-19T00:45:14 < Tectu> izua, http://upload.wikimedia.org/wikipedia/commons/8/84/Time_Travel_Method-2.svg  makes it clear
2012-08-19T00:45:15 <+izua> i guess part of the growing trend on arm's sales is due to free software/linux
2012-08-19T00:45:38 < Tectu> izua, but over all: I like the movie. thank you very much for the recommendation!
2012-08-19T00:45:58 < zyp> no, it's due to people putting computers in their pockets
2012-08-19T00:46:52 < zyp> stating there would be no smartphones if linux weren't around since most smartphones are based on linux is a fallacy
2012-08-19T00:47:09 < zyp> linux being the most suitable choice doesn't imply there are no alternatives
2012-08-19T00:49:40 <+izua> nope, i'm saying if there was no linux, there would be less sales in arm
2012-08-19T00:49:46 < zyp> consider this: how exactly would android have been less successful if it were built on closed source components, but still licenced to phone manufacturers?
2012-08-19T00:49:59 <+izua> arm would be just some random alternative, i guess.
2012-08-19T00:50:11 < zyp> why?
2012-08-19T00:50:58 <+izua> well, as far as i'm aware, arm is the second targeted arch for linux software, which made it easy to make android
2012-08-19T00:51:05 <+izua> that's just my opinion though
2012-08-19T00:51:16 <+izua> i think the next one is mips
2012-08-19T00:51:24 < zyp> I was about to mention mips
2012-08-19T00:51:25 <+izua> second most targeted*
2012-08-19T00:52:00 < zyp> though, I still don't get the connection between linux and arm?
2012-08-19T00:52:03 <+izua> mh, this is in no way anything else than a belief
2012-08-19T00:52:41 < zyp> arm is chosen because it's the most power efficient architecture, therefore suited to battery powered units
2012-08-19T00:53:05 <+izua> ah?
2012-08-19T00:53:24 <+izua> my belief was that arm gained a large(r) market share due to the explosion of android devices
2012-08-19T00:53:43 <+izua> not that older phones weren't running arm7s and such
2012-08-19T00:53:48 < zyp> who did they steal that market share from?
2012-08-19T00:53:51 < zyp> exactly
2012-08-19T00:55:10 < BrainDamage> actually nearly every phone runs an arm chip, and I don't mean the one that interfaces with the user
2012-08-19T00:55:38 < BrainDamage> the last IF modem is implemented in an arm chip
2012-08-19T00:55:57 < BrainDamage> since 10 years or so
2012-08-19T00:56:23 <+izua> ouch
2012-08-19T00:56:33 < zyp> IF?
2012-08-19T00:57:14 < BrainDamage> intermediate frequency
2012-08-19T00:57:16 <+izua> why wouldn't intel be so iffy about people making x86 descriptions?
2012-08-19T00:57:35 <+izua> just because they also are in the business of manufacturing the chips, while arm only sells the IP?
2012-08-19T00:58:40 < BrainDamage> RF demodulators implement superhereterodine downconversion in 90% of the cases, in multiple steps, each step is called IF
2012-08-19T00:59:02 < BrainDamage> the last downconversion stage and demodulation is done in software
2012-08-19T00:59:19 < zyp> where do you have this information from?
2012-08-19T00:59:21 < BrainDamage> downconversion = frequency shifting, aka multiplying by a sine and bandpassing
2012-08-19T00:59:31 < BrainDamage> about the arm chips?
2012-08-19T00:59:40 < BrainDamage> look at the openbts speech
2012-08-19T00:59:56 <+izua> BrainDamage: the superhet action is awesome
2012-08-19T01:00:02 < zyp> :)
2012-08-19T01:00:03 <+izua> it also happens in the brain, say, with binaural beats
2012-08-19T01:00:30 < BrainDamage> how the gsm RF system works, I also had to study for univ
2012-08-19T01:00:48 < BrainDamage> my specialization is actually RF
2012-08-19T01:00:56 < BrainDamage> & integrated circtuis
2012-08-19T01:01:15 < Laurenceb_> i thought most stuff was single conversion now?
2012-08-19T01:01:33 < BrainDamage> you mean zero-if?
2012-08-19T01:01:50 < BrainDamage> I'm not up to date to the last 2 years or so
2012-08-19T01:02:05 < BrainDamage> but cellphone radio requirements are ridicolously strict
2012-08-19T01:02:21 < BrainDamage> and I'm rather skeptical they can meet them with zero if archs
2012-08-19T01:02:37 <+izua> hm.
2012-08-19T01:03:23 <+izua> so that dmitry grinberg with emulators worked on the android multitasking code
2012-08-19T01:04:21 < zyp> I actually work with modems, but I can't really say anything due to NDA

2012-08-19T02:33:36 < emeb> having _so_ much fun trying to figure out why ADC1 on  my F405 isn't generating any data...

2012-08-19T02:35:48 < emeb> hard to imagine a situation where SPI data is arriving so fast you can't stand a 1 cycle pause. SPI is at least 8 cycles per word.

2012-08-19T13:50:29 < dongs> haha.
2012-08-19T13:52:04 < dongs> probably the latter.
2012-08-19T13:57:57 < cjbaird> Was called away to cure a hardware issue on the APANA servers yesterday. Besides the adventure of being stranded on a train platform for 4 hours overnight, I've wound up with a 4-port serial card w/ 16550 DIPs all over it.. Conflicted with throwing it out-- it's hardware of Historical Importance[tm] ('this serial card gave Australia its first public internet access..'), and I'm old enough to remember how awesome 16550s were.. (
2012-08-19T13:57:58 < cjbaird> compared to the 8250/16450)
2012-08-19T14:02:31 < cjbaird> Back in 1986, I knew a guy who designed and sold his own make of PC UART card and was selling them for AU$50 each.. (when others were ~$150)
2012-08-19T14:03:25 < cjbaird> This AST fourport was probably about $400 new.
2012-08-19T14:05:37 < Thorn> donate it to http://www.computerhistory.org/ or something
2012-08-19T14:06:33 < dongs> cjbaird: is that the buffered uart
2012-08-19T14:07:12 < dongs> i think i had that shit on a card so i could take full advantage of my u.s. robotics courier modme
2012-08-19T14:07:58 < cjbaird> d: yep, 16 byte FIFO (16550a, so it actually works)
2012-08-19T14:09:14 < cjbaird> The 4port originally came with 8250s, soldered on. I snipped the chips off, cleaned it up and added sockets, and then bought 2 16550a for ?$60 each. When I could afford it, I filled the remaining 2 sockets.

2012-08-19T20:27:27 < emeb_mac> Getting tired of whacky errors with stlink. Ordered a BMPM - maybe that will be more reliable.
2012-08-19T20:28:47 <+Steffanx> :D :D
2012-08-19T20:28:53 <+Steffanx> maybe? :P
2012-08-19T20:29:07 < emeb_mac> definitely?
2012-08-19T20:29:49 <+Steffanx> For sure
2012-08-19T20:30:13 < emeb_mac> Good to know. Hopefully BMPM disables DMA when it's flashing.
2012-08-19T20:30:32 < emeb_mac> I think that's 90% of the problem with stlink.
2012-08-19T20:30:49 <+Steffanx> Don't know about that
2012-08-19T20:32:58 <+Steffanx> Perhaps zyp knows
2012-08-19T20:33:48 < emeb_mac> Maybe. I mentioned it to karlp a few months back when I tracked it down. No interest in addressing it tho.
2012-08-19T20:34:25 < emeb_mac> But I don't think zyp uses stlink.
2012-08-19T20:34:55 <+Steffanx> I mean perhaps he knows that the bmp
2012-08-19T20:34:59 <+Steffanx> does
2012-08-19T20:35:11 < emeb_mac> ah - yeah. AFAIK he uses bmp
2012-08-19T20:35:12 < zyp> haven't checked
2012-08-19T20:35:33 < emeb_mac> zyp: you use DMA in your apps though, right?

2012-08-19T20:36:21 < zyp> emeb_mac, not in a way that would interfere with flashing
2012-08-19T20:36:55 < emeb_mac> so far I've found most use of DMA interferes w/ flashing via stlink
2012-08-19T20:36:57 <+Steffanx> Laurenceb and only 433/4mhz and 868 are useful ( legal to use )?
2012-08-19T20:37:30 < emeb_mac> stlink doesn't turn off DMA, so it's still writing to SRAM while you upload data via SWD.
2012-08-19T20:38:25 < emeb_mac> since data to be flashed is buffered in SRAM, it is often corrupted by the DMA that's still active and you get a bad flash.
2012-08-19T20:39:10 < Laurenceb_> Steffanx: yes
2012-08-19T20:39:29 < zyp> I haven't used DMA in a way such that it would continue running long after the cpu is halted
2012-08-19T20:39:29 < emeb_mac> I tried modifying the stlink source to do resets, disable DMA, etc, but w/o success.
2012-08-19T20:39:47 < emeb_mac> zyp:  ah - that might be an issue.
2012-08-19T20:40:05 < emeb_mac> I tend to let ADC DMA free-run into a buffer.
2012-08-19T20:42:56 < emeb_mac> I could probably work around that - interrupt at the end of a scan cycle and retrigger by soft command.

2012-08-19T21:04:28 < emeb> Hmmm. No joy. Continuous ADC conversions appears to be required for DMA to work w/o intervention.
2012-08-19T21:05:01 < emeb> ie - you can't scan channels in single conversion mode.
2012-08-19T21:06:36 < zyp> huh?
2012-08-19T21:07:25 < zyp> the way I've been using ADC with DMA is to start a set of conversions sweeping all channels once then terminating
2012-08-19T21:08:00 < emeb> Yeah - that's what I tried.
2012-08-19T21:08:43 < emeb> I set scan mode, disabled continuous conversion, set up DMA and enabled an ISR on the DMA TC.
2012-08-19T21:09:07 < emeb> In the ISR I clear the IRQ and do a software restart of the ADC.

2012-08-19T21:41:01 < emeb> zyp: got a link to some source for the way you set up the ADC for a single set of conversions?
2012-08-19T21:43:07 < zyp> hmm, no
2012-08-19T21:43:45 < emeb> didn't see any ADC stuff in suzumebachi...
2012-08-19T21:43:55 < zyp> I looked through it now, I'm actually using continous conversion
2012-08-19T21:44:19 < zyp> it's old, it only exists in the old F1 branch, haven't used ADC on F4 yet
2012-08-19T21:44:28 < zyp> http://cgit.jvnv.net/suzumebachi/tree/telemetry.cpp
2012-08-19T21:44:49 < emeb> Looking at the F4 docs it seems CC is needed for scanning. w/o CC you just get a one conversion, no scanning.
2012-08-19T21:45:32 < zyp> let me check the reference manual
2012-08-19T21:46:10 < emeb> RM0090 section 10.3.4, 10.3.5
2012-08-19T21:46:40 < zyp> see 10.3.8
2012-08-19T21:47:20 < emeb> seems to contradict my experience.
2012-08-19T21:49:05 < zyp> do you set the SCAN bit?
2012-08-19T21:49:33 < emeb> Yep.
2012-08-19T21:49:43 < emeb> Just tried again - appears to work as desired.
2012-08-19T21:50:01 < emeb> more flakiness from the programmer :P
2012-08-19T21:50:16 < emeb> (not specifying if that's me or the stlink :) )
2012-08-19T21:51:35 < emeb> Now need to see if a similar mode of operation is possible with the I2S input DMA.
2012-08-19T21:55:21 < emeb> Nope - I2S is an unstoppable stream, so DMA will run continuously even when the ARM halts unless you explicitly disable it.
2012-08-19T21:55:58 < zyp> won't it stop when it runs out of memory?
2012-08-19T21:56:19 < zyp> or would it just overwrite it's own buffer?
2012-08-19T21:56:42 < emeb> I've got DMA in circular mode, so it overwrites it's own buffer.
2012-08-19T21:57:08 < emeb> Don't know what happens if DMA gets to the end and data keeps coming if it's not in circular mode.
2012-08-19T21:57:44 < zyp> if it's not in circular mode, it will stop when the transfer count is exhausted
2012-08-19T21:58:45 < emeb> OK - so the trick there would be to take it out of circular mode and restart DMA at TC.
2012-08-19T21:59:14 < TitanMKD> emeb or just check your code managing the buffer is fast enough in all case and it's hard realtime
2012-08-19T21:59:54 < emeb> TitanMKD: My code is fast enough. The problem is DMA continuing to run when the ARM is retasked for flashing code.
2012-08-19T22:00:12 < TitanMKD> emeb I use circular buffer with slave SPI for sampling at 3.39Mhz and that work fine
2012-08-19T22:00:35 < emeb> TitanMKD: yeah - circular buffer for I2S data works great for my app in normal situations.
2012-08-19T22:00:48 < TitanMKD> emeb you can do this code through interrupt and call interrupt when buffer flip
2012-08-19T22:00:55 < TitanMKD> to ensure you do not miss anything
2012-08-19T22:01:05 < emeb> But when I use stlink to flash code, the I2S DMA keeps running and corrupts the code as it's being written.
2012-08-19T22:02:45 < TitanMKD> emeb just stop the DMA during that step
2012-08-19T22:02:57 < emeb> ideally the stlink flash stub would disable all pending hardware operations, including DMA, but it doesn't bother to do so.
2012-08-19T22:03:24 < zyp> no, the stlink host software should do it before uploading the flasher stub
2012-08-19T22:03:37 < TitanMKD> ha ok
2012-08-19T22:04:03 < emeb> zyp: I've tried adding reset commands to the stlink host software but that hasn't helped.
2012-08-19T22:04:35 < emeb> probably doin' it rong, but it's hard to tell.
2012-08-19T22:09:26 < emeb> Anyway - will be interesting to see if BMP has this same issue. Should have one shortly...

2012-08-19T22:51:31 < TitanMKD> just to do like a switch ;)
2012-08-19T22:51:52 < TitanMKD> but i imagine performance are maybe not very good less than 100MHz

2012-08-19T22:52:39 < TitanMKD> emeb yes of course we can avoid to use it but it can be great ;)
2012-08-19T22:53:19 < TitanMKD> emeb especially for simple logic to simplify routing and multiplex X signal as input and only few at output
2012-08-19T22:54:04 < TitanMKD> and because those signal can be I2C bidir it's cool to do that
2012-08-19T22:54:04 < emeb> TitanMKD: so which part families support bidir in hardware?
2012-08-19T22:54:44 < emeb> I assume this is internal to the part - outside is no biggie of course.
2012-08-19T22:54:51 < TitanMKD> emeb i speak about VHDL code for pass-through switch it work on all CPLD/FPGA it's not specific
2012-08-19T22:54:53 < zyp> pretty much every family supports bidirectional IOs, no point in using it for internal signals
2012-08-19T22:55:06 < TitanMKD> emeb but i have never tested it i hope that work
2012-08-19T22:55:59 < TitanMKD> zyp yes but i speak about bidirectional autosense or if your prefer passthrough switch

2012-08-19T23:21:27 < TitanMKD> http://ossmann.blogspot.fr/2012/06/introducing-hackrf.html
2012-08-19T23:21:30 < TitanMKD> a good intro ;)
2012-08-19T23:21:41 < BrainDamage> ok, you don't want to answer my question
2012-08-19T23:21:47 < TitanMKD> BrainDamage for 300US$ it will be 1 board full
2012-08-19T23:22:14 < BrainDamage> which means? all 3?
2012-08-19T23:22:54 < TitanMKD> there's tons of alternative board it's work in progress and Michael Ossmann is validating the hi/lo freq board licorice/lollipop
2012-08-19T23:23:09 < TitanMKD> BrainDamage final board will be all in one
2012-08-19T23:23:19 < TitanMKD> it's for prototypes/validation all those boards
2012-08-19T23:23:41 < TitanMKD> i have only jellybean & lemondrop
2012-08-19T23:23:44 < BrainDamage> ok, so half of the price of an USRP
2012-08-19T23:23:45 < TitanMKD> like on the photo
2012-08-19T23:24:01 < TitanMKD> BrainDamage yes but it will be maybe 8 layers ;)
2012-08-19T23:24:25 < TitanMKD> so 300US$ for such board will be a really competitive price especially we can Transceive data ;)
2012-08-19T23:24:34 < BrainDamage> so can usrp
2012-08-19T23:24:45 < TitanMKD> yes but USRP is not opensource ;)
2012-08-19T23:24:47 < BrainDamage> btw, fiy, end users don't care about amount of layers, they care about system specs
2012-08-19T23:24:52 < BrainDamage> it is opensource
2012-08-19T23:24:59 < BrainDamage> firmware, schematic, etc
2012-08-19T23:25:08 < TitanMKD> yes all is available on github look hardware & software
2012-08-19T23:25:15 < emeb> Looks pretty good. If they can do a fully usable system for ~$300 then they'll have Ettus USRP whipped

2012-08-19T23:31:22 < Laurenceb_> interesting
2012-08-19T23:31:30 < Laurenceb_> so how the hell do they do the huge range?
2012-08-19T23:31:39 < Laurenceb_> IF at 2.4GHz or something?
2012-08-19T23:31:52 < emeb> must be other boards for other ranges. Not all with one set of hardware.
2012-08-19T23:32:07 < BrainDamage> lol @ "Korea WiBro™"
2012-08-19T23:32:20 < emeb> don't wi me bro!
2012-08-19T23:32:30 < BrainDamage> you could chain down/upconverters
2012-08-19T23:32:34 < BrainDamage> ala spectrum analyzers
2012-08-19T23:32:36 < TitanMKD> Laurenceb 2.4GHz is a part of the signal
2012-08-19T23:32:48 < BrainDamage> it'll be rather painful to work tough
2012-08-19T23:33:03 < TitanMKD> but it can really do 100MHz to 6Ghz or at least 100MHz to 2.4GHz ;)
2012-08-19T23:33:24 < Laurenceb_> oh
2012-08-19T23:33:26 < Laurenceb_> epic
2012-08-19T23:34:03 < Laurenceb_> but most stuff ive seen with that much range has issues with LO harmonics
2012-08-19T23:34:19 < Laurenceb_> e4000 solves the problem using a CMOS RF filter
2012-08-19T23:35:45 < TitanMKD> anyway i'm not the designer ;)
2012-08-19T23:36:12 < TitanMKD> all the hw is done by michael ossmann
2012-08-19T23:36:21 < Laurenceb_> my e4000 dvbt dongle works well
2012-08-19T23:38:06 < TitanMKD> but you can only receive ;)
2012-08-19T23:38:25 < TitanMKD> I want to transmit will be fun to debug some stuff

2012-08-20T16:34:32 < cjbaird> The pre-USB Macintoshes actually had an RS422 serial port, rather than the usual RS232.. and it was implimented with a dual op-amp as a buffer. I realised by myself that it made TTL-serial cables very easy ('just switch the wires around on the the tx+/tx- and rx+/rx- pins'), without the 1489/max232 and their crap needed.

2012-08-21T06:16:56 < ossifrage> do you get the result as it is read or not until the entire group is done?
2012-08-21T06:17:13 < dongs> You get end of conversion interrupt if you want, whihc is when all the stuff is done
2012-08-21T06:17:35 < ossifrage> do you have code someplace that does this?
2012-08-21T06:18:18 < dongs> No but ADC1_DMA example will do what you want
2012-08-21T06:18:29 < dongs> just add more channels w/ADC_RegularChannelConfig bla bla
2012-08-21T06:18:45 < ossifrage> ah, I'm using libopencm3,

2012-08-21T07:18:14 < emeb_mac> how
2012-08-21T07:18:38 < dongs> the nak was causing _er interrupt (of course) but Iwasn't passing that fact to the code
2012-08-21T07:18:50 < dongs> so Iw as returning true (ack successful) from code when it wasnt
2012-08-21T07:19:49 < emeb_mac> so just proper error handling
2012-08-21T07:21:29 < dongs> Ya
2012-08-21T07:22:33 < ossifrage> Yes, you really want to use ADC DMAs, otherwise you can spend way too much time in the interrupt handler.
2012-08-21T07:22:54 < emeb_mac> dma is ur frend
2012-08-21T07:25:23 < ossifrage> I managed to completely swamp the chip with ADC interrupts, I guess I need to use a timer to trigger the next read cycle

2012-08-21T10:26:30 < dongs> cool observation with ms5611 sensor today. i had gui rolling showing the fluctuating pressure graph on screen. then i left office. came back a bit later, and saw waht looked like a low pressure glitch on gui. wasn't much, but it was a definite dip. sat around staring at the graph to see if it was something software/hardware related. nothing. then I remembered I opened the door to get to hte office.tried it agian, opening door would generate a dip :)

2012-08-21T14:38:14 < karlp> it has an ethernet port?
2012-08-21T14:38:29 < karlp> so, the entire frame becomes a usb-serial adapter?
2012-08-21T14:41:07 < claude_work> yes or a usb-ethernet adapter . but just exposed to the linux running on the df3120. that way you can use the linux console or a networking connection from you host pc to debug the df3120
2012-08-21T14:43:11 < cjbaird> Mistyped "df3210" into Google Image search and got a whole lot of fattie 'burlesque' pics. :/
2012-08-21T14:43:23 < claude_work> lol :)
2012-08-21T14:44:54 < karlp> I just get other models of pciture frames
2012-08-21T14:45:01 < karlp> google must know what you like ;)
2012-08-21T14:46:13 < karlp> so, with this usb-gadget ethernet, you don't actually have ethernet anywhere, you have a usb cable between the frame (device) and some other machine (host) and they see it as an ethernet link between the two?
2012-08-21T14:47:21 < cjbaird> yep. the openmoko neo phone is somewhere I've used it. "ifconfig usb0 192.168.1.200 ..."
2012-08-21T14:50:50 < zyp> I've been using it for android units
2012-08-21T14:51:04 < zyp> they use RNDIS

2012-08-21T20:08:05 <+dekar> for 100mbit/s?
2012-08-21T20:08:23 <+dekar> my server has 100mbit/s it comes with 5tb per month
2012-08-21T20:08:26 <+Steffanx> For a 'normal' user .. sure
2012-08-21T20:08:32 <+Steffanx> Here it's FUP, no idea how much FUP is
2012-08-21T20:08:37 < zyp> is that 100 up/down each or combined?
2012-08-21T20:08:49 < cjbaird> There's The Big Lie that it costs ~dollars to send each gigabyte overseas.. in spite of peering arrangements & etc.
2012-08-21T20:08:50 <+dekar> idk, not living in aus
2012-08-21T20:09:49 <+dekar> here in germany I pay 22€ per month for unmetered 16mbit/s
2012-08-21T20:10:04 < cjbaird> 4GB = facebook machine owners. They have another 4GB account for their iPhones...
2012-08-21T20:10:05 <+dekar> also I can cancel my contract monthly
2012-08-21T20:11:02 < cjbaird> Anyone from Norway/Sweden? ...well stfu about you having better connection deals on your mobile phones.. -_-
2012-08-21T20:11:16 < BrainDamage> I pay 16€ for  10 unmetered in italy
2012-08-21T20:11:21 < cjbaird> Phone plans here are worst than those even in the States.
2012-08-21T20:11:31 < emeb> that's saying something...
2012-08-21T20:11:34 < BrainDamage> phones here unfortunately are all capped
2012-08-21T20:11:44 < BrainDamage> 1GB for 6€ :/
2012-08-21T20:11:58 <+Steffanx> 6 what?
2012-08-21T20:12:03 < BrainDamage> euro
2012-08-21T20:12:08 < zyp> I'm in Norway, but I don't have an expensive phone plan
2012-08-21T20:12:11 < BrainDamage> no utf-8 support?
2012-08-21T20:12:11 <+Steffanx> Lucky you BrainDamage
2012-08-21T20:12:15 <+dekar> I pay 3.50€ for 100mb/month on 3g
2012-08-21T20:12:21 <+Steffanx> ^^
2012-08-21T20:12:23 < cjbaird> ...I think that answers the earlier question about 'still living the consequences'? :P :)
2012-08-21T20:13:05 < zyp> my plan includes half a gig per month, I'm probably using aroundt 100 or so at most
2012-08-21T20:14:02 < zyp> 100 MB*
2012-08-21T20:14:16 < zyp> so far I'm at 87 MB this month
2012-08-21T20:14:47 < BrainDamage> oh and I forgot, the 6€ data plan, includes 1k SMS vs national numbers, of any operator
2012-08-21T20:14:52 < cjbaird> ..make that 4.8GB of debs...
2012-08-21T20:15:12 < BrainDamage> if I exceed, it's 1MB/€ tough :/
2012-08-21T20:15:28 < zyp> hmm, my plan is 800 minutes, 800 messages, 400 MB
2012-08-21T20:15:36 < karlp> cjbaird: they're not that bad, I was back in aus for 2 months in feb/march, and 30$/month got me plenty of data on the phone
2012-08-21T20:15:47 < zyp> for 250 NOK or so
2012-08-21T20:15:48 < karlp> we both used our phones for whatever we wanted around aus
2012-08-21T20:15:52 <+dekar> for me it just is throttled to like 10kbyte/s once I am over 100mb - takes them a day or two to enable though :D
2012-08-21T20:16:50 < cjbaird> $30/month is acceptible for vistors, but that's $500/year too much for those of us stuck here. :/
2012-08-21T20:18:22 < zyp> cjbaird, that doesn't sound expensive to me
2012-08-21T20:19:00 < zyp> here in norway, everything is expensive
2012-08-21T20:19:36 < zyp> until you start comparing it to what people earn
2012-08-21T20:19:44 < karlp> cjbaird: beers in aus were $10 in bars,
2012-08-21T20:19:55 < karlp> I can't complain about $30 a month for a full phone service

2012-08-21T20:20:58 < karlp> but what's your phone bill in terms of beers :)
2012-08-21T20:21:06 <+dekar> zyp, isn't a pizza like 20usd in norway?
2012-08-21T20:21:23 < zyp> if you order one?
2012-08-21T20:21:29 <+dekar> yeah
2012-08-21T20:21:29 < BrainDamage> they should normalize the average life cost by the average wage, I'd be interesting to have a country independent quality of life cost index
2012-08-21T20:21:46 < zyp> I ordered a large pizza the other day, I paid >$30
2012-08-21T20:21:52 <+Steffanx> lol
2012-08-21T20:21:55 < cjbaird> Beers in regular bars are usually $4.5-$6; although that's crap like Tooheys New.
2012-08-21T20:21:58 < karlp> yeah, too many things are "that's expensive!" without any relation to what pays are, and what costs are.
2012-08-21T20:22:08 < karlp> cjbaird: bullshit. a schooner in a local maybe
2012-08-21T20:22:14 < karlp> try getting a pint in town
2012-08-21T20:22:16 <+Steffanx> That's why the hamburger ( or was it big-mac) index exists :P
2012-08-21T20:22:34 < karlp> Steffanx: but that doens't relate to the fact that bigmacs are not always an equal portion of wage
2012-08-21T20:22:48 < cjbaird> Only tourists buy beers in George St. :P
2012-08-21T20:23:13 < karlp> I'm not talking about tourist traps, I grew up in brisbane, I was out with friends in brisbane perth and melbourne
2012-08-21T20:23:15 < BrainDamage> for instance, take that pizza index
2012-08-21T20:23:23 < karlp> and we were consistently above $9 for beers in bars
2012-08-21T20:23:24 < BrainDamage> pizza here costs 4-5€ on average
2012-08-21T20:23:26 < zyp> the nice part about living in norway is that other countries are so cheap :p
2012-08-21T20:23:35 < BrainDamage> but I live in italy, there's a pizzeria ever 300m
2012-08-21T20:23:38 <+Steffanx> You are in pizzaland, that d oesn't count
2012-08-21T20:23:42 < BrainDamage> exactly
2012-08-21T20:23:51 < BrainDamage> and hamburger index doesn't count in usa
2012-08-21T20:23:53 <+Steffanx> :P
2012-08-21T20:24:03 <+Steffanx> It was bigmac btw
2012-08-21T20:26:08 < cjbaird> I've settled on the 'Mars Bar Index' being more representative..
2012-08-21T20:28:13 <+Steffanx> Sure?
2012-08-21T20:28:52 <+Steffanx> You should select a non-us product
2012-08-21T20:29:10 < karlp> nestle counts as US?

2012-08-21T20:31:44 < karlp> not taht, I was saying that a milky way is not a mars bar
2012-08-21T20:31:52 < karlp> it's like saying a snickers is a mars bar, if you ignore the peanuts
2012-08-21T20:32:08 < karlp> gah, I'm arguing on the internet
2012-08-21T20:32:15 < karlp> this is what happens when I'm working in the hot room.
2012-08-21T20:32:25 < karlp> need to go back to the ariconditioned part of the office
2012-08-21T20:32:29 < BrainDamage> here there's not even milky way bars around
2012-08-21T20:32:41 < cjbaird> Comparible when making trade and commodity price comparisons, obviously.
2012-08-21T20:33:20 < karlp> milky ways are subtantially cheaper than mars bars though...
2012-08-21T20:33:55 < BrainDamage> also, commodity cost is largely dependent on local preferences and availability
2012-08-21T20:34:15 < BrainDamage> if a country is big on mars bars, might have them cheap
2012-08-21T20:34:33 < BrainDamage> chance is if you buy say, haribo liquorice, it won't be as cheap
2012-08-21T20:34:43 < BrainDamage> hence why you want an average of most commonly consumed goods

2012-08-21T23:08:27 < Laurenceb_> is it ok to use a voltaile global to pass data between to interrupt service routines in chibios?
2012-08-21T23:09:04 < zyp> as a data buffer, sure
2012-08-21T23:09:15 < zyp> keep in mind syncing accesses to it though
2012-08-21T23:13:26 < Laurenceb_> yeah
2012-08-21T23:13:39 < Laurenceb_> i want data to pass between adc1 and adc2 callbacks
2012-08-21T23:14:01 < Laurenceb_> i think they should have same preemption priority, so cannot interrupt one another
2012-08-21T23:14:06 < Laurenceb_> so global should work?
2012-08-21T23:22:02 < zyp> sure, if it's ever only accessed from an ISR
2012-08-21T23:22:51 < zyp> you can probably even get by with not declaring it volatile then, since it can't change during the execution of an ISR, except by that ISR
2012-08-21T23:28:08 < Laurenceb_> ok

2012-08-21T23:42:12 < Laurenceb_> that would make sense
2012-08-21T23:42:25 < zyp> so I'm assuming that only a reset will make a read return 0 bytes
2012-08-21T23:42:37 < Laurenceb_> so the getline function blocks or loops until it gets \r\n
2012-08-21T23:43:18 < Laurenceb_> guess i need a separate thread for it then

2012-08-21T23:45:11 < Laurenceb_> its part of the same stream
2012-08-21T23:45:36 < Laurenceb_> or BaseChannel rather
2012-08-21T23:46:45 < Laurenceb_> well ill try chprintf from the main thread first then try experimenting with control commands
2012-08-21T23:48:56 < Laurenceb_> ideally id have a blocking thread that reads the usb and interprets, then send commands the the main thread via a mailbox

2012-08-22T17:13:11 < zyp> it's wired to be able to provide power to the micro side, that's why you can't draw power from it
2012-08-22T17:14:14 < Laurenceb> i know
2012-08-22T17:14:34 < Laurenceb> actually they broke the spec as they should have a fet to tie usb cable sheild at the host side
2012-08-22T17:15:08 < Laurenceb> a 0.1" header fits nicely onto the top of a sot23, so ill do that
2012-08-22T17:15:25 < Laurenceb> then use a jumper to allow powering off micro usb
2012-08-22T17:16:45 < zyp> Laurenceb, ref. on that spec
2012-08-22T17:17:25 < zyp> looking at OTG spec, can't find anything about the shield
2012-08-22T17:18:07 < Laurenceb> hmm maybe not
2012-08-22T17:18:09 < Laurenceb> In OTG applications the shield may be DC grounded at both ends of the cable.

2012-08-22T17:24:20 < upgrdman_> in many consumer electronics if you hold down a pushbutton it will do something (like increment a value) once per second for the first few seconds, then it will speed up if you keep holding down the button. what would be the best way to implement that with the stm32f4? i'm guessing a timer that is triggered on a rising edge, with an ISR that reconfigures the ARR after x ISR calls?

2012-08-22T17:44:58 < Laurenceb> 1.7 Three phase mixing
2012-08-22T17:44:58 < Laurenceb> Three phase mixing combines high speed clocks to create a local oscillator clock with slower edge speeds.
2012-08-22T17:44:58 < Laurenceb> This is used to reduce the high frequency harmonics, which when operating at low frequencies would be
2012-08-22T17:44:58 < Laurenceb> within the tuner bandwidth. This feature prevents interferer signals mixing with harmonics of the local
2012-08-22T17:44:58 < Laurenceb> oscillator frequency, increasing the dynamic range of the tuner..
2012-08-22T17:44:59 < Laurenceb> It is recommended that three phase mixing should be used for VHF operation

2012-08-22T18:12:45 < jpa-> cjbaird: you could take just the average values for each 16x16 block, depending on what kind of processing you want :)
2012-08-22T18:14:22 < zyp> I want to be able to format the descriptor into a nice buffer at compile time, without having to explicitly declare structs to wrap other structs
2012-08-22T18:14:44 < cjbaird> Yep. Somewhere I've got a minimalist jpeg decoder that includes that trick.

2012-08-22T19:27:12 < Laurenceb> anyone know how chprintf knows to usb usb cdc?

2012-08-22T19:27:27 <+Steffanx> nu
2012-08-22T19:27:31 < Laurenceb> i setup usb cdc and chprintf seems to work automatically
2012-08-22T19:27:40 < TitanMKD> Laurenceb it's in config file IIRC
2012-08-22T19:27:48 < Laurenceb> as BaseChannel is set to CDc in the CDC inti?
2012-08-22T19:27:59 < Laurenceb> which config?
2012-08-22T19:28:13 < TitanMKD> I do not remember but it's configurable
2012-08-22T19:41:36 < Laurenceb> static const ShellConfig shell_cfg1 = {

2012-08-22T20:10:33 < zyp> I wrote ACM descriptors for my stuff, now it enumerates as ACM
2012-08-22T20:15:09 < karlp> what's the difference between acm and cdc again? whether AT commands are supported or something?
2012-08-22T20:15:45 < zyp> ACM is a subclass of CDC
2012-08-22T20:16:10 < zippe> CDC is "things that are streams of bytes talking to something else"
2012-08-22T20:16:18 < zippe> ACM is "things like modems"
2012-08-22T20:18:05 < zyp> the reason ACM is used is that it's the simplest class that are commonly supported by class drivers

2012-08-22T22:44:08 < cjbaird> It's a Vimicro VC0706/0703, and I was checking out what output sizes it handled by poking random values into the eeprom data register responsible.
2012-08-22T22:44:40 < cjbaird> It uses a 24LC16B soic8, so I might be able to unpoke the damage..
2012-08-22T22:49:47 < melonstorm> Hey. I compiled a GCC toolchain with summon-arm-toolchain for a Cortex-M3 CPU (LPC1768). gcc refuses to compile, though, because it can't find cc1.

2012-08-22T23:15:06 < zyp> you could try starting over, choosing an empty directory for PREFIX instead of /usr

2012-08-23T02:13:03 < Erlkoenig> Branch with Link register, change arm mode ... oder so
2012-08-23T02:13:10 < Erlkoenig> BX ist ein sprung
2012-08-23T02:13:17 < Erlkoenig> ohne rückkehr
2012-08-23T02:14:45 < melonstorm> Ui. :o
2012-08-23T02:14:49 < melonstorm> Ohne Rückkehr!?
2012-08-23T02:15:02 < melonstorm> Schrecklich. D:
2012-08-23T02:15:06 < melonstorm> Das ist ja wie mit den Lemmingen.
2012-08-23T02:15:16 < Erlkoenig> ja das was "jmp" auf x86 oder avr ist :D
2012-08-23T02:15:24 < melonstorm> Ich weiss. :3
2012-08-23T02:15:27 < Erlkoenig> top :D
2012-08-23T02:15:29 < zyp> you're missing a lot of input when you are talking in a language we other doesn't speak
2012-08-23T02:15:48 < zyp> at this rate you might as well just converse in private
2012-08-23T02:16:29 < Erlkoenig> this way, i can happily explain a lot bullshit to him :>
2012-08-23T02:16:41 < zyp> blx is a call to a function pointer
2012-08-23T02:17:06 < zyp> unless the operand is a label, then it means «please crash»
2012-08-23T02:18:09 < zyp> same for bx except it's a jump and not a call
2012-08-23T02:18:23 < zyp> and bx lr is a return
2012-08-23T02:19:56 < melonstorm> zyp, right now, I'm getting this warning:
2012-08-23T02:20:13 < melonstorm> /usr/bin/../lib/gcc/arm-none-eabi/4.6.2/../../../../arm-none-eabi/bin/ld: warning: cannot find entry symbol _start; defaulting to 0000000000008000
2012-08-23T02:20:48 < Erlkoenig> zyp: but "blx foobar" effectively calls the C-Function foobar, and doesn't crash... or am i getting everything wrong?!
2012-08-23T02:21:23 < zyp> Erlkoenig, it's «bl foobar»
2012-08-23T02:21:30 < karlp> yeah, but one of the ways of using blx is arm only,
2012-08-23T02:21:38 < zyp> exactly
2012-08-23T02:21:39 < karlp> and arm instruction on cm3 goes bang bang boom
2012-08-23T02:22:01 < Erlkoenig> ah... on arm cores that have both arm and thumb "blx foobar" should work?
2012-08-23T02:22:08 < zyp> yes
2012-08-23T02:22:32 < zyp> the x means «change to arm mode»
2012-08-23T02:22:48 < Erlkoenig> no, "change to arm mode IF the 'foobar' label depicts an ARM function"
2012-08-23T02:23:01 < zyp> when you use blx on registers it means «change to arm mode if lower bit in register is not set»
2012-08-23T02:23:06 < zyp> no.
2012-08-23T02:23:06 < Erlkoenig> blx should also work on thumb-only cores - if the 'foobar' label is a thumb function
2012-08-23T02:23:34 < Erlkoenig> "'foobar' is a thumb function" == "lower bits of foobar address is 1"
2012-08-23T02:23:37 < Erlkoenig> ;)
2012-08-23T02:23:53 < zyp> that's wrong, in machine code they are stored without the lower bit
2012-08-23T02:23:55 < zyp> IIRC
2012-08-23T02:24:17 < Erlkoenig> im quite sure that the lower bit is stored, which confused me somewhat ;)
2012-08-23T02:24:37 < Erlkoenig> that lowest bits tells blx about how to switch
2012-08-23T02:24:54 < zyp> however, it's probably legal to write either blx or bl, because the linker will rewrite the instruction depending on what you link to
2012-08-23T02:25:54 < Erlkoenig> at least "my" linker generates both "blx" and "bl" instructions, for a thumb2-only-controller
2012-08-23T02:26:32 < karlp> if anyone had any clue how this conversation started, it might be relevant.
2012-08-23T02:26:36 < zyp> blx on registers is valid, blx on labels _will_ change to arm mode if left that way
2012-08-23T02:27:09 < karlp> (grepping objdump for blx is a pretty good way of finding out that you've fucked up the linker flags, and it's helpfully linked in some arm code)
2012-08-23T02:27:25 < Erlkoenig> oh, it generates only "blx <register>"
2012-08-23T02:27:28 < zyp> the address encoded into a bl/blx label opcode is a 16-bit word address, so there is no low-bit in it
2012-08-23T02:27:39 < zyp> Erlkoenig, that's what I said :p
2012-08-23T02:28:09 < Erlkoenig> karlp: my code works so i think it's not fucked up ;)
2012-08-23T02:28:44 < Erlkoenig> zyp: and when the core is in ARM mode, does BLX switch to Thumb mode?
2012-08-23T02:29:04 < karlp> if your code works, what on earth are we talking about this for?
2012-08-23T02:29:19 < Erlkoenig> to explain melonstorm what it does. :D
2012-08-23T02:29:20 < melonstorm> Erlkoenig, things still don't work. :v
2012-08-23T02:29:43 < melonstorm> Because there's no _start.
2012-08-23T02:29:43 < Erlkoenig> i'm not surprised. :D
2012-08-23T02:29:45 < melonstorm> For some reason.
2012-08-23T02:29:46 < zyp> melonstorm, you are missing either a linker script or the startup code or both
2012-08-23T02:29:54 < melonstorm> zyp, I bet I'm missing the fomrer!
2012-08-23T02:29:57 < Erlkoenig> it took me days to get my stm32 running :D
2012-08-23T02:29:58 < zyp> either that or they are wrong
2012-08-23T02:31:15 < melonstorm> Holy shit.
2012-08-23T02:31:30 < melonstorm> There's a picture of an oscilloscope in the examples folder that I got with this devboard...
2012-08-23T02:31:37 < melonstorm> That thing's, like... looking awfully battered.

2012-08-23T02:34:05 < Erlkoenig> whats that board connected to the white usb cable?
2012-08-23T02:34:12 < zyp> mbed
2012-08-23T02:35:11 < melonstorm> zyp, how would I write a linker script? I don't think I can find one.
2012-08-23T02:35:22 < zyp> you should find one
2012-08-23T02:35:30 < zyp> linker script goes hand in hand with startup code
2012-08-23T02:35:32 < melonstorm> The example files are all parts of Keil uVision projects.
2012-08-23T02:36:13 < Erlkoenig> the example linker script by ST has a bug... it has cost me a few gray hairs to figur it out...
2012-08-23T02:36:33 < melonstorm> The .uvproj file is an XML file, and it actually has a "StartupFile" entry.
2012-08-23T02:36:54 < zyp> if you are just starting out and looking to get to know stm32, I suggest going with libopencm3 or something and looking at the included examples
2012-08-23T02:37:04 < Erlkoenig> he is using an LPC controller
2012-08-23T02:37:07 < melonstorm> ^
2012-08-23T02:39:40 < melonstorm> Hmm.
2012-08-23T02:43:12 < melonstorm> http://code.google.com/p/lpc17xx-ld/source/browse/lpc1768.ld
2012-08-23T02:43:21 < melonstorm> Well, I guess that's what I'm looking for.
2012-08-23T02:43:58 < Erlkoenig> looks evil enough.
2012-08-23T02:44:34 < melonstorm> So how do I tell Eclipse to tell ld to use this?
2012-08-23T02:44:52 < Erlkoenig> gcc ... -T lpc1768.ld

2012-08-23T02:45:42 < melonstorm> Woo.
2012-08-23T02:46:10 < melonstorm> Lessee.
2012-08-23T02:46:50 < melonstorm> Of course, that stuff's CodeSourcery stuff. Hmm.
2012-08-23T02:47:19 < Erlkoenig> i suggest you to do the whole thing only using make and gcc, without eclipse
2012-08-23T02:47:37 < melonstorm> Yeah, but I'll still need a linker script or whatever.
2012-08-23T02:48:00 < Erlkoenig> http://code.google.com/p/lpc17xx-ld/source/browse/lpc1768.ld <-- i thought that was your linkerscript
2012-08-23T02:48:09 < melonstorm> Well, it is.
2012-08-23T02:48:11 < melonstorm> But that's for CS3.
2012-08-23T02:48:42 < melonstorm> And if I remove the three entries from GROUP(), I get...
2012-08-23T02:48:45 < Erlkoenig> whats CS3? CodeSourcery3?
2012-08-23T02:48:47 < melonstorm>  /media/Volume/Code/linux_eclipsews/test3/lpc1768.ld:206: undefined symbol `__cs3_interrupt_vector_cortex_m' referenced in expression
2012-08-23T02:48:49 < melonstorm> Yep.
2012-08-23T02:49:41 < melonstorm> The __cs3_interrupt_vector_cortex_m is defined in startup_LPC17xx.s, so I'm a little confused...
2012-08-23T02:49:42 < Erlkoenig> than you probably have to find a linker script for gcc...
2012-08-23T02:49:50 < melonstorm> Erlkoenig, CS3 is GCC.
2012-08-23T02:49:55 < Erlkoenig> oh hm
2012-08-23T02:49:58 < melonstorm> They just had to add their own Senf to it.
2012-08-23T02:51:39 < melonstorm> The joke's even that it -does- find __cs3_reset_cortex_m. Apparently.
2012-08-23T02:55:21 < melonstorm> Erlkoenig, what now?
2012-08-23T02:57:18 < Erlkoenig> did you link the startupcode correctly?
2012-08-23T02:57:51 < melonstorm> I'm not sure.
2012-08-23T02:58:48 < melonstorm> Erlkoenig, http://hastebin.com/raw/jorigoxagu
2012-08-23T02:59:48 < melonstorm> Hmm, wait. Huh.
2012-08-23T03:01:24 < melonstorm> Ah. I didn't.
2012-08-23T03:01:31 < melonstorm> How it worked. Woohoo.
2012-08-23T03:03:27 < melonstorm> Woot! It works!
2012-08-23T03:03:36 < melonstorm> The code's running!
2012-08-23T03:03:43  * melonstorm dances!
2012-08-23T03:03:57 < Erlkoenig> how do you flash your controller? openocd?
2012-08-23T03:04:07 < melonstorm> J-Link. OpenOCD doesn't want to work.
2012-08-23T03:04:27 < melonstorm> The board also got a J-Link emulator, so that's pretty much why.
2012-08-23T03:04:47 < melonstorm> I can also flash it via the ISP, but I want to be able to debug.
2012-08-23T03:05:39 < melonstorm> The odd thing, still, is that startup_LPC17xx.s isn't being included in the compilation, though...
2012-08-23T03:05:51 < melonstorm> I have to manually bind in the .o file I built myself.
2012-08-23T03:05:54 < Erlkoenig> what, you're doing something wrong
2012-08-23T03:06:07 < melonstorm> Well, it -is- working.
2012-08-23T03:11:24 < melonstorm> I can compile code, translate it to a .bin file with a utility called hex2bin, then transfer it onto the board with the J-Link command line utility.
2012-08-23T03:12:32 < Erlkoenig> hex2bin? shouldn't objcopy be able to do that as well?
2012-08-23T03:12:46 < melonstorm> I don't know, Erlkoenig...
2012-08-23T03:12:54 < melonstorm> I'm not sure if it can read those .hex files.
2012-08-23T03:13:04 < Erlkoenig> it can surely read what the linker generates :D
2012-08-23T03:13:49 < melonstorm> Can you figure out how it needs to be called?
2012-08-23T03:14:00 < Erlkoenig> objcopy --help
2012-08-23T03:15:21 < Erlkoenig> and why hex2bin... doesn't your gcc generate an elf file?
2012-08-23T03:16:41 < melonstorm> Erlkoenig, it does, it does.
2012-08-23T03:17:05 < melonstorm> arm-none-eabi-objcopy -v test3.elf  -O binary test3.bin
2012-08-23T03:17:09 < melonstorm> This seems to work.
2012-08-23T03:17:45 < melonstorm> Yup, it does. MD5 sums match.
2012-08-23T03:18:52 < melonstorm> Hah. And I could change that in the IDE, too. I mean.
2012-08-23T03:19:00 < melonstorm> To make it output a binary image instead of ihex.
2012-08-23T03:19:17 < Erlkoenig> hmm, funnily "-Wl,--format=binary" doesnt work on the linker command :S
2012-08-23T03:20:23 < melonstorm> Time to set up debugging and uploading.
2012-08-23T03:21:24 < melonstorm> I got another plugin for that.
2012-08-23T03:21:28 < melonstorm> Zylin Embedded debug.
2012-08-23T03:22:32 < zippe> Erlkoenig: that's because that's an argument to the compiler driver, not the linker
2012-08-23T03:23:27 < Erlkoenig> that's why i prepended it with "-Wl"
2012-08-23T03:27:45 < karlp> lpc13x and 17x have linker scripts and startup files, and examples in libopencm3
2012-08-23T03:27:56 < melonstorm> karlp, it's working.
2012-08-23T03:37:44 < dongs> sup blogs
2012-08-23T03:39:42 < melonstorm> Erlkoenig, the problem with OpenOCD is that it... doesn't do something right .

2012-08-23T03:45:34 < dongs> hoo ok.
2012-08-23T03:45:59 < melonstorm> dongs, J-Link's what my devboard using.
2012-08-23T03:46:10 < melonstorm> There's actually a STM32 on it that emulates a J-Link.
2012-08-23T03:46:38 < melonstorm> I can flash the LPC1768 with the official J-Link software, but not with OpenOCD.
2012-08-23T03:47:01 < dongs> right
2012-08-23T03:48:31 < dongs> http://www.segger.com/jlink-ob.html probably this right?
2012-08-23T03:48:57 < melonstorm> dongs, it's a clone, I presume. Not an official Segger chip.
2012-08-23T03:49:03 < melonstorm> Hence why it's a STM32.
2012-08-23T03:49:06 < dongs> no
2012-08-23T03:49:11 < dongs> that is official
2012-08-23T03:49:16 < dongs> that OB thing supports STM32.
2012-08-23T03:49:25 < melonstorm> There's no sticker, at least.
2012-08-23T03:49:25 < dongs> tehre's nothing to "clone", firmware for those is inside jlinkarm.dll.
2012-08-23T03:49:35 < melonstorm> I'm on Linux, dongs.
2012-08-23T03:49:45 < dongs> righto. thats probably your biggest problem right thre :)
2012-08-23T03:50:45 < melonstorm> dongs, why so?
2012-08-23T03:51:16 < dongs> i'd rather not get into that discussion
2012-08-23T03:52:28 < dongs> if you dont already know the answer, nothing I say will make a difference.

2012-08-23T05:30:22 < melonstorm> Even though GCC compiles things just fine.
2012-08-23T05:30:32 < dongs> maybe you need to setup some include paths or something.
2012-08-23T05:30:43 < dongs> uint32_t shit is in stdint.h... it should have that included by default.. I 'd imagine.
2012-08-23T05:31:23 < melonstorm> Even including that doesn't help, dongs, and Eclipse does find that file and parse it.

2012-08-23T05:40:11 < zippe> if the latter, and you're using make, then you need to arrange for the compiler invocations printed by make to have useful pathnames in them

2012-08-23T05:45:28 < zippe> I am *not* doing Eclipse support.
2012-08-23T05:45:37 < zippe> Unless you want to fix my I2C issues.
2012-08-23T05:45:41  * melonstorm can't.
2012-08-23T05:51:21 < dongs> haha :)
2012-08-23T05:56:34 < melonstorm> Oddly enough, typedeffing uint32_t works, dongs, but including stdint.h doesn't.
2012-08-23T05:56:35 < melonstorm> wtf?
2012-08-23T06:00:30 < melonstorm> It doesn't really help, either, that stdint.h is definitely in the include paths.
2012-08-23T06:09:02 < melonstorm> Looks like the CMSIS files supplied with the examples were pretty outdated, though.

2012-08-23T07:24:36 < LeelooMinai> Actually hot glue has similar melting temp as led-free solder
2012-08-23T07:31:46 < dongs> um where are you getting that?

2012-08-23T07:32:01 < dongs> hotglue is liquid at < 200C
2012-08-23T07:35:29 < LeelooMinai> Yes, so is lead-free solder
2012-08-23T07:35:44 < LeelooMinai> Or rather leaded
2012-08-23T07:44:32 < dongs> who the fuck uses leaded solder in 2012
2012-08-23T07:47:34 < LeelooMinai> Most hobbyists afaik
2012-08-23T07:48:02 < LeelooMinai> Go to ##electronics and as if anyone uses it:)
2012-08-23T07:48:13 < LeelooMinai> ask*
2012-08-23T07:49:40 < dongs> by the same analogy, if I g oto #electronics and ask how many use arduino
2012-08-23T07:49:49 < dongs> means I should just drop everything and switch to atmel
2012-08-23T07:50:42 < LeelooMinai> Not many people there use it actually
2012-08-23T07:51:04 < BjoernC> I'll gonna hate lwip - i don't know WHY this lib compiles the first time - after that eclipse finds errors and that wihtout changes at the code the only "change" was a make clean
2012-08-23T07:52:07 < LeelooMinai> dongs, Besides, I didn't tell you to use leaded solder, did I?  I just pointed out that it will melt below 200 deg C
2012-08-23T07:52:17 < LeelooMinai> So your analogy sucks
2012-08-23T07:52:48 < dongs> no, i was referring to hobbyists using leaded solder
2012-08-23T07:53:11 < LeelooMinai> Many do for the simple reason it's cheaper - you can get it cheap from China
2012-08-23T07:53:25 < LeelooMinai> It's also easier to work with
2012-08-23T07:54:29 < LeelooMinai> When you are a hobbyist you usually don't have to worry about ROHS and such
2012-08-23T07:54:48 < dongs> i find leadfree much easier to work with even handsoldering shit
2012-08-23T07:55:10 < LeelooMinai> I don't see why - it has higher melting temp
2012-08-23T08:05:28 < zippe> LeelooMinai: that also means that it cools to crystalisation faster
2012-08-23T08:06:57 < LeelooMinai> Yes, which is a problem when soldering
2012-08-23T08:09:47 < zippe> You probably haven't seen the crap that dongs builds
2012-08-23T08:09:56 < zippe> Or you'd understand why he doesn't feel that way
2012-08-23T08:10:11 < zippe> Personally, I use silver when soldering.
2012-08-23T08:10:32 < zippe> And titanium for everything else.

2012-08-23T10:14:44 < Tectu> does it still need space or will it be optimized out?

2012-08-23T10:16:58 < dongs> wouldnt unused: just be a label.

2012-08-23T10:25:25 < Tectu> zyp, is it just to fix the compiler warning or does it have other positive effects?
2012-08-23T10:25:30 < Tectu> i mean the (void)foo; stuff
2012-08-23T10:25:40 < Tectu> claude_work, bite back!
2012-08-23T10:26:04 < claude_work> i did :)
2012-08-23T10:26:19 < Tectu> now i am scared.
2012-08-23T10:26:55 < claude_work> just sucked out the wasp poison from my finger
2012-08-23T10:27:25 < Tectu> poison? where the hell do you life that wasps do have poison
2012-08-23T10:27:58 < claude_work> hmm poison / venom ?
2012-08-23T10:28:13 < jpa-_> Tectu: it just removes the warning
2012-08-23T10:28:35 < Tectu> thanks jpa-_
2012-08-23T10:31:17 < zyp> Tectu, it's just telling the compiler «I know this variable is unused, it's supposed to be so you don't need to warn me about it»
2012-08-23T10:31:58 < zyp> and that's a good thing, because you should really treat all warnings like something is wrong
2012-08-23T10:38:16 < dongs> zyp, lol @ teh url i pasted in closedpilot
2012-08-23T10:40:29 < Tectu> something C related: I do have a very simple linked list, only single linked. How do i delete every node in it? is it the best to reinizialize the FIRST pointer or delete them one by one?
2012-08-23T10:41:05 < dongs> you can free teh shit it points to then nuke the list..
2012-08-23T10:41:32 < Tectu> by just NULL-ing the first pointer the memory stays used, correct... hmm
2012-08-23T10:41:44 < dongs> yes, ob viosuly, well depending how you allocated it.
2012-08-23T10:43:21 < Tectu> dongs, what do you mean with "how you allocated it"?
2012-08-23T10:43:32 < dongs> Tectu: i dunno, it depends what your nodes point to.
2012-08-23T10:43:34 < Tectu> i allocated the size for one node whenever i add one
2012-08-23T10:43:43 < dongs> you mean like mallolc or something?
2012-08-23T10:43:45 < Tectu> dongs, to the next node or NULL ?!
2012-08-23T10:43:48 < dongs> cjbaird: which lemote shit exactly are you looking for
2012-08-23T10:44:00 < Tectu> dongs, more like chHeapAlloc()   (chibios malloc)
2012-08-23T10:44:07 < dongs> my pal is waiting with throbbing dong to service me
2012-08-23T10:44:15 < dongs> o riet, well
2012-08-23T10:44:23 < dongs> whatever you alloc y ou gotta free
2012-08-23T10:44:31 < dongs> wehre did you steal thelinkedlist shit from?
2012-08-23T10:44:40 < zyp> what dongs says is true
2012-08-23T10:44:49 < dongs> look at old glib sores (gtk dudeS). they have pretty clean slist/dlist implementations
2012-08-23T10:44:55 < zyp> don't you have a chHeapFree() to go with that chHeapAlloc()?
2012-08-23T10:45:31 < dongs> on embedded and known size lists it might not evne be useful to malloc/free all the fucking time
2012-08-23T10:45:38 < dongs> just make t he nodes pointers into some preallocated area
2012-08-23T10:45:43 < dongs> of course it all depends waht youre doing

2012-08-23T10:59:06 < cjbaird> The last word I heard was for production to start happening in May, after a supply issue was settled.
2012-08-23T10:59:47 < cjbaird> The 8133 is almost twice as heavy at the 8101B I've got-- hopefully in batteries. :P

2012-08-23T11:05:51 < dongs> price is around 800$
2012-08-23T11:06:02 < dongs> pretty spendy for a shitbook.
2012-08-23T11:09:04 < zyp> if I get this working like I want, I could wrap this into simple functions like «make all the interface/cdc/endpoint descriptors I need for an ACM interface»
2012-08-23T11:09:22 < zyp> and then just call that twice if I need two ACM interfaces

2012-08-23T16:14:44 < Tectu> how can I make this working? the 3th element must be a  char* which will be written to the display     http://pastebin.com/r2zveKer
2012-08-23T16:15:01 < Tectu> while argument number to, the i in DRAW_PEN() must be an int
2012-08-23T16:15:12 < Tectu> i tried   (char*) i   but that didn't work
2012-08-23T16:15:46 < jpa-_> so you want to convert an integer to string?
2012-08-23T16:15:48 < Tectu> i guess atoi() should work?
2012-08-23T16:15:50 < Tectu> yeah

2012-08-23T16:15:58 < Tectu> itoa() *
2012-08-23T16:16:07 < jpa-_> itoa, yeah, if your libc has that
2012-08-23T16:16:08 < Tectu> it shall enumerate on the display ;)
2012-08-23T16:16:13 < jpa-_> otherwise snprintf
2012-08-23T16:16:17 < Tectu> cool
2012-08-23T16:16:22 < Tectu> thanks for the idea with sprintf
2012-08-23T16:16:53 < jpa-_> always use snprintf, sprintf (without buffer size limit) is playing with the devil
2012-08-23T16:17:14 <+Steffann> Who cares? :P
2012-08-23T16:17:30 <+Steffann> And why? In this case it shouldn't matter
2012-08-23T16:17:32 < Erlkoenig> if PENS < 10, just write:  char x [2] = "0\0"; for (i = 0.... ) {  x[0] = '0' + i; gdispDrawString (..., &x, ...); }
2012-08-23T16:17:35 < Erlkoenig> that would be faster
2012-08-23T16:17:58 < jpa-_> Steffann: if you never use sprintf, you can just remove it and be sure that you never use it :)
2012-08-23T16:18:25 < jpa-_> if you use sprintf where it is ok, you have to check and re-check every point where it is used
2012-08-23T16:18:41 < jpa-_> true, what Erlkoenig suggests is a fine hack also
2012-08-23T16:18:52 < Tectu> of course i don't have itoa

2012-08-23T17:35:27 < jpa-_> yeah, the holes look strange
2012-08-23T17:35:35 < Tectu> indeed

2012-08-23T17:38:01 < Tectu> BrainDamage, resistive
2012-08-23T17:38:14 < Tectu> BrainDamage, less than 18$ including shipping
2012-08-23T17:38:59 < BrainDamage> all those cheap modules are resistive :/
2012-08-23T17:39:06 < karlp> nothing wrong with resistive :)
2012-08-23T17:39:11 < BrainDamage> I cannot seal it
2012-08-23T17:42:27 < Tectu> resistive are good for controlling, but not for professional drawings ;)
2012-08-23T17:43:00 < BrainDamage> I just want to be able to embed in a glass frame and make it waterproof
2012-08-23T17:43:11 < BrainDamage> or even plastic

2012-08-23T22:55:40 < zyp> they probably thank you for the «friendly communication» to make you feel bad about how you came across :p

2012-08-23T22:58:20 < Erlkoenig> also funny "3 Yahre Garantie". It's "Jahre", for "Years", in german, and "garantie" is "warranty"
2012-08-23T22:58:21 < BrainDamage> "hi friend!" , and I'm like "what?"
2012-08-23T22:58:29 < zyp> yeah, it's probably just some stock english they have
2012-08-23T22:58:49 <+Steffann> Yeah, this probably is some standard message from the (chinese) seller
2012-08-23T22:59:02 < Erlkoenig> one should learn chinese and mail them in chinese directly ;)
2012-08-23T22:59:11 < BrainDamage> also, the culture is so different that I wouldn't even exclude it being common courtesy addressing strangers as friend
2012-08-23T22:59:40 < BrainDamage> altought it does feel awkward
2012-08-23T22:59:45 <+Steffann> True, in Asia the 'all' seems to do that
2012-08-23T22:59:49 <+Steffann> Except in jappieland
2012-08-23T23:00:00 < zyp> «special price for you my friend» comes to mind
2012-08-23T23:00:11 <+Steffann> Or isn't dongs a standard jappylander?
2012-08-23T23:00:28 < zyp> everybody wants to be your friend when you are giving them money :p
2012-08-23T23:00:44 <+Steffann> It was only 19 euro
2012-08-23T23:00:59 <+Steffann> even less, 15
2012-08-23T23:01:20 < Erlkoenig> would be interesting to know what you can buy for 15eur in china...
2012-08-23T23:01:27 < zyp> Steffann, it still adds up
2012-08-23T23:01:30 < BrainDamage> a lot of things
2012-08-23T23:01:49 <+Steffann> You can buy CRAP :)
2012-08-23T23:01:50 < BrainDamage> go to dx.com and do a search with price limit of 20$
2012-08-23T23:01:59 < BrainDamage> and you'll get a very rough idea
2012-08-23T23:02:03 < Erlkoenig> well not only technology stuff ;)
2012-08-23T23:02:03 <+Steffann> Not everything from dx is crap though
2012-08-23T23:02:08 < zyp> dx isn't even cheap
2012-08-23T23:02:25 < BrainDamage> yeah, I often find better deals on ebay than dx
2012-08-23T23:02:58 < zyp> dx is well known, so they can afford to charge more due to the reputation
2012-08-23T23:03:04 <+Steffann> I don't care about 1 euro more or less :P
2012-08-23T23:03:21 < emeb> if you're not careful searching on dx you'll end up looking at their "adult toys" - eeewwww!
2012-08-23T23:03:35 < Erlkoenig> waaat
2012-08-23T23:03:36 <+Steffann> You don't like that?
2012-08-23T23:03:58 < BrainDamage> I find the adult section of dx hilarious
2012-08-23T23:04:08 < emeb> yep
2012-08-23T23:04:10 < Erlkoenig> of course everyone would love sticking china quality ... things into their body openings

2012-08-23T23:04:59 < BrainDamage> I find hilarious to see, not to use
2012-08-23T23:04:59 <+Steffann> No one can beat the chinese ...
2012-08-23T23:05:31 <+Steffann> You'll probably pay more for your copper wire, than the coil it sell when bought in china :P
2012-08-23T23:06:25 < Erlkoenig> hmokay, i dont know about the chinese ones, the stuff you usually get in european stores is definitively more expensive than a coil... :D

2012-08-23T23:45:20 < Laurenceb_> thats pre tax
2012-08-23T23:45:43 < Laurenceb_> gets me about 12 square inches
2012-08-23T23:46:04 < Laurenceb_> but it scales very little with area
2012-08-23T23:46:54 < BrainDamage> mmm? that's odd, usually pcb costs are pretty linear with area, what's there for inital barrier?

2012-08-23T23:47:38 < zyp> NRC
2012-08-23T23:48:18 < Laurenceb_> ?

2012-08-23T23:50:15 < zyp> something like that
2012-08-23T23:50:28 < BrainDamage> yes, but I was wondering exactly which are those
2012-08-23T23:50:50 < BrainDamage> even tooling usage is still somehow proportional to area due to wear and time slots
2012-08-23T23:51:18 < BrainDamage> an in his case, it seems even dominant
2012-08-23T23:51:45 < BrainDamage> maybe the initial production setup that still has to pay off
2012-08-23T23:51:53 < BrainDamage> and they mortage on the users
2012-08-23T23:52:05 < zyp> by the way, are you talking about area per board or area of all boards together?

2012-08-23T23:57:31 < Laurenceb_> ah
2012-08-23T23:57:43 < BrainDamage> why "debug" ?
2012-08-23T23:57:44 < Erlkoenig> oh, is there any small handy board with a STM32F4, an ethernet jack and a few GPIO's for around 20Euros?
2012-08-23T23:57:47 < Laurenceb_> it just redirects to blogspot.co.uk
2012-08-23T23:57:49 < zyp> TitanMKD, how can I comment on your power regulators if I can't see how they are connected?
2012-08-23T23:57:57 < TitanMKD> Debug because I will do full software like bus pirate with terminal ;)
2012-08-23T23:58:09 < zyp> TitanMKD, I've looked on the board pics before, and something about it doesn't look very sensible
2012-08-23T23:58:26 < BrainDamage> Erlkoenig: add an ethernet module to a f4 discovery
2012-08-23T23:58:48 < TitanMKD> zyp what doesn't look very sensible ?
2012-08-23T23:59:28 < Erlkoenig> BrainDamage: the problem is i fear soldering such delicate parts myself ;)
2012-08-23T23:59:41 < BrainDamage> Erlkoenig: no soldering necessary
2012-08-23T23:59:48 < Erlkoenig> there is a ready module?
2012-08-23T23:59:59 < zyp> TitanMKD, the way you have seperate regulators for lipo-powered and usb-powered usage
--- Day changed Fri Aug 24 2012
2012-08-24T00:00:01 < BrainDamage> try ebay "ethernet module"
2012-08-24T00:00:07 < BrainDamage> you'll be swamped with results
2012-08-24T00:00:20 < TitanMKD> zyp in fact i changed that
2012-08-24T00:00:54 < BrainDamage> TitanMKD: why is it the board called "debug" ?
2012-08-24T00:00:55 < zyp> TitanMKD, well, I can't comment on how it looks now if I can't see the schematic for it
2012-08-24T00:01:32 < TitanMKD> zyp if you do not want the LipO stuff you should not populate components under microUSB connector and populate the big 3.3V regulator on the bottom of the board
2012-08-24T00:01:40 < zyp> Erlkoenig, the F4 already contains an ethernet MAC, so you only need a PHY
2012-08-24T00:01:50 < TitanMKD> zyp give me your Email and i will send you the schematic
2012-08-24T00:02:07 < Erlkoenig> zyp: i know, i'd like a ready module that fits exactly to this mac
2012-08-24T00:02:41 < TitanMKD> zyp the good stuf is with more than 40GPIO this little board can also read NandFlash ;)
2012-08-24T00:03:14 < zyp> Erlkoenig, http://www.ebay.com/sch/i.html?_nkw=dp83848
2012-08-24T00:04:09 < Erlkoenig> with this one i can take advantage of the MAC in the STM32F4? nice. ;)
2012-08-24T00:05:45 < TitanMKD> Erlkoenig on my board there's no Ethernet
2012-08-24T00:05:58 < TitanMKD> Erlkoenig as the LQFP64 STM32F4 does not include ethernet
2012-08-24T00:06:15 < Erlkoenig> a pity...
2012-08-24T00:06:55 < zyp> the LQFP100 on the discovery board does
2012-08-24T00:07:16 < TitanMKD> and anyway my board will be really more expensive than STM32F4 discovery
2012-08-24T00:07:35 < TitanMKD> the discovery price is just impossible to reach
2012-08-24T00:07:52 < TitanMKD> it's the price of the MCU when bought by 10 or 100 :(
2012-08-24T00:08:09 < karlp> Erlkoenig: the vodafone branded entrylevel huawei phones are pretty solid physically.
2012-08-24T00:08:20 < qyx_> TitanMKD: according to datasheet f4 in lqfp64 has full mii interface available
2012-08-24T00:08:38 < TitanMKD> qyx_ ha i was thinking it was not present
2012-08-24T00:08:40 < BrainDamage> TitanMKD: how is your board any better than a discovery?
2012-08-24T00:09:00 < TitanMKD> BrainDamage it's 60mm*37mm with a cool case ;)
2012-08-24T00:09:09 < zyp> qyx_, the problem is that MAC is only present in F407, and only F405 is available in LQFP64
2012-08-24T00:09:24 < Erlkoenig> karlp: oh thanks... :)
2012-08-24T00:09:25 < TitanMKD> BrainDamage and with lipo you can plug it to a phone ...
2012-08-24T00:09:51 < qyx_> zyp: why there is such option then?
2012-08-24T00:09:53 < qyx_> hm
2012-08-24T00:10:05 < zyp> qyx_, there aren't
2012-08-24T00:10:08 -!- phantoxeD [~destroy@a95-92-89-24.cpe.netcabo.pt] has quit [Ping timeout: 268 seconds]
2012-08-24T00:10:10 < zyp> check page 13 of datasheet
2012-08-24T00:10:17 < TitanMKD> like the USB HighSpeed the ULPI stuff was too big and expensive :(
2012-08-24T00:10:34 < TitanMKD> but anyway USB FS OTG is very good
2012-08-24T00:10:43 < zyp> TitanMKD, OTG_HS is available in F405
2012-08-24T00:10:57 < TitanMKD> zyp yes but it requires lot of components and use too much IO
2012-08-24T00:11:19 < karlp> Erlkoenig: for stm32 with ethernet, the hitex comsticks maybe? http://www.hitex.com/index.php?id=stm32-comstick
2012-08-24T00:11:24 -!- phantoneD [~destroy@a95-92-89-24.cpe.netcabo.pt] has joined ##stm32
2012-08-24T00:11:31 < karlp> not the nicest connectors though
2012-08-24T00:11:44 < zyp> TitanMKD, how is a single HS PHY chip «a lot of components»?
2012-08-24T00:12:09 < qyx_> zyp: i see now, that's very good point as i was planning to reroute one my board from lqfp100 to 64
2012-08-24T00:12:15 < qyx_> but never noticed that detail :S
2012-08-24T00:12:28 < TitanMKD> zyp but it requires in addition 8io and that remove SPI and other very important peripherals
2012-08-24T00:13:05 < TitanMKD> zyp it's why i cancelled this option to have a multi-purpose debug board/hack board with maximum peripherals and IO to do pratically all possible stuff/protocol ;)
2012-08-24T00:13:10 < zyp> TitanMKD, «important» really depends on your application, it's not important if you don't need it for that particular application
2012-08-24T00:13:57 < TitanMKD> zyp i plan to use an extension board for USB HS ;)
2012-08-24T00:14:07 < Erlkoenig> karlp: nice, but a bit more expensive than hoped for... regarding that there are 20 Eur. kits available with an AVR, and some sort of SPI->Ethernet adapter...
2012-08-24T00:14:11 < TitanMKD> zyp like an FT2232H ;)
2012-08-24T00:14:43 < karlp> Erlkoenig: stellaris launchpad is in the works, it should have the ethernet port on it?
2012-08-24T00:14:44 < TitanMKD> which could be also a JTAG/SWD debugger ;)
2012-08-24T00:15:08 < karlp> zyp: why the DP83848? personal success with it? what's the difference vs any other phy?
2012-08-24T00:15:39 < zyp> TitanMKD, and a quick glance at the AF map tells me that SPI1 can be mapped to pins that's not used for ULPI, so your argument about SPI is invalid.
2012-08-24T00:16:12 < zyp> karlp, I just grabbed the one that came with my waveshare kit and read the number off it
2012-08-24T00:16:20 < karlp> ahh :)
2012-08-24T00:16:22 < TitanMKD> zyp i want 2 SPI ;)
2012-08-24T00:16:26 < Erlkoenig> karlp: waaaat no stm32... but okay ;)
2012-08-24T00:16:31 < TitanMKD> zyp and also I2C and 2 USART
2012-08-24T00:16:40 < karlp> Erlkoenig: a cortex is a cortex?
2012-08-24T00:16:42 < TitanMKD> zyp you cannot have all if you add ULPI
2012-08-24T00:16:44 < zyp> SPI3 is also available on non-ULPI pins
2012-08-24T00:16:48 < karlp> yeh, easier to not switch of course :)
2012-08-24T00:17:07 < TitanMKD> zyp i checked with MicroXplorer during hours
2012-08-24T00:17:07 < karlp> olimex has an f4 board with ethernet, but I havne't seen it for $20
2012-08-24T00:17:19 < karlp> Erlkoenig: what avr+ethernet boards for $20 have you seen?
2012-08-24T00:17:20 < TitanMKD> zyp and it was a no way to have all peripherals i have :(
2012-08-24T00:17:40 < zyp> TitanMKD, then it's time to choose a larger package, problem solved.
2012-08-24T00:17:42 < Erlkoenig> karlp: http://www.pollin.de/shop/dt/MTQ5OTgxOTk-/Bausaetze_Module/Bausaetze/Bausatz_AVR_NET_IO.html   this one
2012-08-24T00:18:01 < qyx_> tfuj
2012-08-24T00:18:04 < qyx_> enc28j60
2012-08-24T00:18:21 < karlp> Erlkoenig: well, you could drop an enc28j60 module on any of the discovery boards for under $20,
2012-08-24T00:18:22 < qyx_> it has longer errata than datasheet
2012-08-24T00:18:27 < TitanMKD> zyp it's will be not a tiny debugger like the BusPirate and the size 60mm*37mm is just the best i think
2012-08-24T00:18:32 < karlp> but the enc28j60 isn't super popular I thougth
2012-08-24T00:18:43 < qyx_> it is popular, but buggy
2012-08-24T00:18:43 < BrainDamage> it is between hobbysts
2012-08-24T00:18:46 < TitanMKD> zyp anyway wait for the next design with an other MCU it will have all anyone dream ;)
2012-08-24T00:18:48 < Erlkoenig> karlp: well the idea was to not use the enc*, but rahter the mac of the f4
2012-08-24T00:18:50 < BrainDamage> because it's cheap
2012-08-24T00:19:07 < zyp> karlp, the dp83848 is just as cheap
2012-08-24T00:19:41 < zyp> and to me it seems more sensible to go with the internal MAC than adding another
2012-08-24T00:19:51 < BrainDamage> module wise, no
2012-08-24T00:20:07 < BrainDamage> the enc modules are 4.5$ inc shipping
2012-08-24T00:20:11 < karlp> zyp: yeah, agreed, but the modules aren't quite as common
2012-08-24T00:20:23 < BrainDamage> the dp is 17$ between shipping and module cost
2012-08-24T00:20:55 < BrainDamage> but yes, I'd still use the internal mac
2012-08-24T00:21:16 < zyp> 10 vs 100 Mb/s may also be an argument
2012-08-24T00:21:20 < Erlkoenig> yes, then you can take advantage of the DMA
2012-08-24T00:21:39 < karlp> TitanMKD: youe blog page is miles too wide
2012-08-24T00:21:54 < qyx_> you certainly want to avoid enc* and use internal mac :X
2012-08-24T00:22:06 < qyx_> it is worth 12$ more
2012-08-24T00:22:35 < TitanMKD> karlp ha  why you look it on screen 800*600 ?
2012-08-24T00:22:53 < karlp> no, but I prefer browsers not to be as wide as my screen
2012-08-24T00:23:01 < karlp> on 800x600 your blog would be unusably wide
2012-08-24T00:23:20 < zyp> I used to prefer having my browser as wide as my screen
2012-08-24T00:23:47 < karlp> until you got widescreen screens, so did I
2012-08-24T00:23:52 < zyp> until I got this new display, 2560px is really too wide
2012-08-24T00:23:58 < TitanMKD> anyway if some of you are interested in some protoboard i will have 10 boards
2012-08-24T00:24:17 < TitanMKD> but before to sell anything i will check all is ok
2012-08-24T00:24:59 < TitanMKD> the sw behind will use chibios and all drivers will use DMA ;)
2012-08-24T00:25:35 < TitanMKD> with possibility to launch in // all independant peripherals ;)
2012-08-24T00:25:35 < zyp> so you are selling it as a complete product and not a development board?
2012-08-24T00:25:57 < TitanMKD> zyp yes it's intended to be a complete product with pcb soldered+case+sw like bus pirate
2012-08-24T00:26:41 < TitanMKD> but all is possible just give some PCB with schematic/pcb to solder it yourself ...
2012-08-24T00:26:44 < zyp> I'm not familiar with the bus pirate, where does the lipo come into play?
2012-08-24T00:26:49 < TitanMKD> and the sw will be opensource under github
2012-08-24T00:27:04 < BrainDamage> so it'll come with firmware preprogrammed?
2012-08-24T00:27:26 < TitanMKD> zyp the lipo is intended to be here to connect the board to an android phone and use android with terminal to do stuff
2012-08-24T00:27:36 < TitanMKD> like send data on SPI1 ...
2012-08-24T00:27:36 < karlp> http://www.youtube.com/watch?feature=player_embedded&v=G-OVrI9x8Zs#!
2012-08-24T00:28:47 < TitanMKD> zyp it's why any idea is welcome ;) I can modify stuff
2012-08-24T00:29:37 < zyp> TitanMKD, did any work on the software yet? I'm imagining you should be able to prototype it all on a discovery board
2012-08-24T00:29:55 < BrainDamage> the bus pirate is basically a mcu with firmware to speak some of the classic protocols and redirect to pc
2012-08-24T00:30:09 < TitanMKD> zyp i have already done a full sw with terminal with my other board TRF7970A v1.0 & v1.1
2012-08-24T00:30:57 < TitanMKD> zyp of course all was done using my STM32F4 Discovery (I have even 2 boards ;)
2012-08-24T00:31:33 < zyp> sounds like you're all set then :)
2012-08-24T00:31:54 < TitanMKD> but anyway it's a huge work
2012-08-24T00:32:40 < TitanMKD> but planned to be reusable and C Ansi with abstraction layer to be not linked too much to the HW
2012-08-24T00:32:56 < TitanMKD> it's why chibios is a must ;)

2012-08-24T01:04:19 < Laurenceb_> lol
2012-08-24T01:07:36 < BrainDamage> best are voitenko compressors
2012-08-24T01:07:52 < BrainDamage> shaped charge that propels the light gas gun
2012-08-24T01:08:49 < BrainDamage> according to this: http://www.islandone.org/LEOBiblio/SPBI134.HTM 40km/s :p
2012-08-24T01:09:14 < Laurenceb_> interesting
2012-08-24T01:10:03 < Laurenceb_> didnt know you could get that fast with explosives
2012-08-24T01:11:51 < Laurenceb_> one way to do n-prize :P
2012-08-24T01:13:32 < BrainDamage> does it have to bundle telemetry or can it be a smashed piece of metal? :p
2012-08-24T01:14:18 < Laurenceb_> it just has to be detected
2012-08-24T01:14:37 < Laurenceb_> ive been kind of working of a balloon launched spin stabilised Estes motor
2012-08-24T01:14:40 < Laurenceb_> dont laugh
2012-08-24T01:15:12 < Laurenceb_> i was thinking of taking the casing off on a lathe an adding a nozzle and putting it in a carbon fibre tube
2012-08-24T01:15:23 < Laurenceb_> might reach 100km
2012-08-24T01:15:35 < BrainDamage> nah, keep having all sort of insane ideas daily, and sometimes I even try to realize them ..

2012-08-24T09:09:23 < Tectu> when using mathlib   -lm   and then call stuff like sinf() etc. does it automaticly use the FPU in Cortex-M4?
2012-08-24T09:09:48 < jpa-> if your libm was compiled for hardware floating point
2012-08-24T09:10:04 < Tectu> how can i find out?
2012-08-24T09:10:21 < jpa-> i would check the disassembly for FPU instructions
2012-08-24T09:10:24 < Tectu> and when it is, then it does automaticly use FPU where possible, and don't use where none?
2012-08-24T09:10:38 < Tectu> then not, i guess
2012-08-24T09:11:16 < jpa-> nope, if it is compiled for hardware floating point, it won't work if the FPU is missing
2012-08-24T09:11:42 < jpa-> but some GCC versions also have support for multilib, so that it selects between the precompiled libraries based on the selected processor
2012-08-24T09:11:44 < Tectu> good

2012-08-24T09:21:01 < zyp> also, if your libm is compiled for another float ABI than what you are using, you may find that your application doesn't work correctly

2012-08-24T09:24:49 < zyp> (when you have an FPU, it's faster to be able to pass float function arguments in FPU registers so you don't have to pass them back and forth between FPU and CPU unnecessary)
2012-08-24T09:25:25 < zyp> but that obviously doesn't work when you don't have an FPU
2012-08-24T09:26:05 < zyp> and doesn't work if a function expects arguments in CPU and caller puts them in the FPU
2012-08-24T09:26:27 < Tectu> that makes sense, yeah
2012-08-24T09:26:27 < Tectu> thanks
2012-08-24T09:26:55 < dongs> blogs
2012-08-24T09:27:47 < dongs> and this is why kids use real compilers.
2012-08-24T09:31:05 < jpa-> yeah, when you can't configure it, even dongs can manage!

2012-08-24T17:57:10 < karlp> stdperipfh lib for people who don't like CAPS_EVERYWHERE_ALL_THE_TIME
2012-08-24T17:57:20 < Erlkoenig> BrainDamage: just like the CMSIS or the Std pheriphals library?
2012-08-24T17:57:43 < karlp> Erlkoenig: exactly, but licensed lgpl, not the various mix of things in cmsis and std periph lib
2012-08-24T17:58:11 < Erlkoenig> does the license of the cmsis hinder you from doing anything?
2012-08-24T17:59:20 < dongs> how the fuck can you license a bunch of headers
2012-08-24T18:00:15 < Erlkoenig> apparantly you can license round corners...
2012-08-24T18:00:50 < Erlkoenig> i need a "license text" -> "english text" converter
2012-08-24T18:01:48 < BrainDamage> we all do
2012-08-24T18:01:50 < karlp> some people allege that the licenses in some parts of std periph lib don't allow writing a gpl
2012-08-24T18:02:14 < karlp> writing a gpl app sorry
2012-08-24T18:03:02 < Erlkoenig> the cmsis license seems to allow pretty much anything as long as you state that you used it...
2012-08-24T18:03:18 < zyp> I'll probably go with the bsd license or something when I bother putting a license on my stuff
2012-08-24T18:03:26 < Erlkoenig> gpl is evil after all :>
2012-08-24T18:03:40 < Laurenceb> gpl is ironic

2012-08-24T18:05:16 < Erlkoenig> couldn't one just publish programs and/or source code with no license at all?
2012-08-24T18:05:41 < Laurenceb> i prefer the beerware license
2012-08-24T18:05:45 < zyp> copyright laws says you have copyright by default
2012-08-24T18:06:13 < Erlkoenig> that means nobody can claim "i made it"... which doesnt bother me too much :D
2012-08-24T18:06:18 < Erlkoenig> right?
2012-08-24T18:06:37 < zyp> and that it can't be reproduced without your consent
2012-08-24T18:06:46 < Erlkoenig> oh meh
2012-08-24T18:07:31 < zyp> and then there is different laws in different jurisdictions
2012-08-24T18:08:23 < zyp> licenses were made to handle stuff like that in a standardized manner
2012-08-24T18:08:51 < Erlkoenig> hum+

2012-08-24T18:09:18 < Erlkoenig> what open source license allows for commercial use of my app/lib, as long as nobody claims he made it?
2012-08-24T18:09:31 < karlp> BSD/MIT/X11/Apache
2012-08-24T18:09:34 < Erlkoenig> and doesn't force anybody to opensource something that uses my thingy
2012-08-24T18:09:37 < zyp> yeah
2012-08-24T18:09:52 < zyp> that's pretty much what BSD says

2012-08-24T19:39:04 < cjbaird> Going with larger packets (up to at least 2kB) means less overhead of course, but with random-sized files to download you can end up with a lot of wasted space/time on the last packet.. 512 seems to be the optimal. What a nice little CompSci undergrad prac lab this would make..

2012-08-24T19:52:47 < emeb> Erlkoenig: "no other technical data available" - how you going to hook it up?
2012-08-24T19:53:53 < Erlkoenig> emeb: there *is* data, you just have to know where :D ... http://www.mikrocontroller.net/topic/234687 ... see the attached files, also apparantly someone in that thread managed to get the data from the camera via DCMI
2012-08-24T19:53:59 < cjbaird> D'uh. 'Why don't I just make the last packet smaller?'
2012-08-24T19:54:45 < emeb> Erlkoenig: nice!
2012-08-24T19:55:14 < Erlkoenig> indeed ;) ... i'm just wondering how i will solder it *g*
2012-08-24T19:55:27 < emeb> hotplate reflow!
2012-08-24T19:55:36 < emeb> Just don't melt the plastic.
2012-08-24T19:55:47 < Erlkoenig> yeay... i can barely handle a soldering iron... :D :D
2012-08-24T19:56:00 < BrainDamage> hot plate is easier than manual soldering
2012-08-24T19:56:04 < emeb> Learn. It's not hard.
2012-08-24T19:56:23 < BrainDamage> only requires you to align parts, but that's done when it's cold
2012-08-24T19:56:28 < BrainDamage> and you got all the time you want
2012-08-24T19:56:51 < Erlkoenig> well i will see... have to get a few other things done before i'll start that ;)
2012-08-24T19:57:34 <+Steffann> "Artikel leider ausverkauft." .. too bad Erlkoenig
2012-08-24T19:57:52 < Erlkoenig> oh noes :o
2012-08-24T19:57:56 < Erlkoenig> luckily i bought 3 pieces :D
2012-08-24T19:58:00 <+Steffann> Ah
2012-08-24T19:59:37 < Erlkoenig> maybe they get new shipments later... that shop must have the weirdest sources...
2012-08-24T20:02:56 <+Steffann> Nice .. it does jpeg compression
2012-08-24T20:05:16 < Erlkoenig> yup... maybe one could fit very low-res uncompressed images into the stm32f4 - SRAM and try to recognize structures
2012-08-24T20:05:56 <+Steffann> Or hook up some sram ( too bad it doesn't do sdram )
2012-08-24T20:06:33 < dongs> Auflösung 1608x1208 more like afroslung
2012-08-24T20:06:45 < Erlkoenig> auflösung = resolution ;)
2012-08-24T20:07:18 < Erlkoenig> Steffann: mooore solder-fun ;) ... are there any mikrocontrollers with SDRAM interfaces?
2012-08-24T20:07:36 <+Steffann> lpc4[something] if they're available yet
2012-08-24T20:07:47 <+Steffann> And the big ass ARMs ofcourse
2012-08-24T20:07:48 < Erlkoenig> except from those huge PC-Grade Monsters
2012-08-24T20:08:01 <+Steffann> That lpc is m4 too

2012-08-24T20:13:23 < Erlkoenig> what's patent-worthy about "basic on mikrocontroller" Oo
2012-08-24T20:13:35 < dongs> parallax is trolling
2012-08-24T20:13:44 < dongs> cuz every product they have made to date has been a failure
2012-08-24T20:14:09 < karlp> Seems TI makes the slave transceiver, but not much in the way of slave libraries, can't find any master transceiver, but libmbus looks decent for the software.
2012-08-24T20:14:16 < karlp> seems a little inside out
2012-08-24T20:14:42 < Erlkoenig> also, a simple arduino seems much more powerful - and less expensive
2012-08-24T20:15:21 < zyp> basic stamp existed long before arduino came along
2012-08-24T20:15:21 < dongs> and just as retarded
2012-08-24T20:26:25 < Erlkoenig> also funny is the siemens logo...

2012-08-25T00:18:40 < Laurenceb_> DMA can be set to any peripheral register, and the signal can come from any peripheral?
2012-08-25T00:18:58 < Laurenceb_> so i could have a timer control dma to another timers overflow register?
2012-08-25T00:20:09 < zyp> there is some restrictions on which DMA controllers can access which buses, but yeah, in theory what you are describing is possible
2012-08-25T00:20:24 < Laurenceb_> ok
2012-08-25T00:20:36 < Laurenceb_> im trying to work out a way to do OFDM usinf DMA alone
2012-08-25T00:20:41 < zyp> also, you never stop impressing me by how outrageously silly your ideas are
2012-08-25T00:20:48 < zyp> :p
2012-08-25T00:20:51 < Laurenceb_> heh
2012-08-25T00:21:09 < Laurenceb_> ofdm with pure pwm is impossible
2012-08-25T00:21:19 < Laurenceb_> for n>2 frequencies
2012-08-25T00:21:48 < Laurenceb_> you have to correct the phase slightly as you have orthogonal periods not orthogonal frequencies
2012-08-25T00:22:07 < zyp> your style of working seems like some kind of spaghetti science; just throw every silly idea at the wall and see if anything sticks
2012-08-25T00:22:19 < Laurenceb_> yes
2012-08-25T00:22:39 < zyp> no wonder you're raging so much about stuff that don't work

2012-08-25T00:37:59 < karlp> shouldn't it just shift in zeros?
2012-08-25T00:38:27 < Laurenceb_> what does timer break input do?

2012-08-25T01:35:24 < Laurenceb_> then use the internal trigger output off that ganged timer to reset the other timers
2012-08-25T01:36:18 < Laurenceb_> so in my case i set the ganged timer to overflow on 192, then on overflow it resets the other timers
2012-08-25T01:36:50 < Laurenceb_> as there are 192 periods of the central frequency per integration bin
2012-08-25T01:37:55 < Laurenceb_> no cpu resources involved
2012-08-25T01:40:36 < Laurenceb_> with DMA and some output filtering you could actually generate RF OFDM with this
2012-08-25T01:42:28 < zyp> ok, tell me when you have it working
2012-08-25T01:42:54 < Laurenceb_> lol
2012-08-25T01:43:07 < Laurenceb_> it works atm with interrupt to reset the timers
2012-08-25T01:43:26 < Laurenceb_> *to adjust the reload buffer registers
2012-08-25T01:43:39 < zyp> I mean, tell me when you are actually generating valid RF data that way

2012-08-25T02:42:36 < karlp> if I manually trigger the pin, it gets the edge, it then reads in some expected packet data,
2012-08-25T02:42:49 < karlp> but it should be getting them all the time
2012-08-25T02:42:53 < karlp> I'll find them somewhere
2012-08-25T02:42:56 < karlp> hiding in the dark
2012-08-25T02:44:02 < emeb> anyone here ever use the SWO pin on the SWD interface - useful for reading the debug port & trace info.
2012-08-25T02:44:35 < emeb> Apparently supported by ST-LINK under Windows via the newer Discovery boards.
2012-08-25T02:46:04 < zyp> it's also supported by the blackmagic probe, but I haven't had time to test it yet
2012-08-25T02:46:07 < zyp> but I have plans to
2012-08-25T02:46:43 < karlp> I've made sure the pin is wired on my boards, but never actually used it :)
2012-08-25T02:46:56 < karlp> haven't even worked out the right code to use that would send data there :)
2012-08-25T02:47:25 < emeb> zyp: Really? I haven't seen that anywhere in the bmp docs.
2012-08-25T02:47:43 < zyp> it's exposed on a seperate endpoint

2012-08-25T02:50:10 < zyp> emeb, that's what you get for not going with the standard connector :p
2012-08-25T02:50:23 < karlp> Laurenceb_: plenty of speed for atmega replacements :)
2012-08-25T02:50:24 < zyp> Laurenceb_, except it gets more done per cycle
2012-08-25T02:50:31 < karlp> and way way more periphs
2012-08-25T02:50:38 < BrainDamage> and costs same as atmega
2012-08-25T02:50:39 < emeb> zyp: heh - I thought that was standard - it's what they used on the Discovery boards. :P
2012-08-25T02:51:16 < zyp> I like how my bmp turned out after I «modified» it :p

2012-08-25T02:51:24 < Laurenceb_> what did you do?
2012-08-25T02:52:01 < zyp> remove the 20-pin connector (I have the old one) and solder a 20-pin to mini-10-pin adapter there instead
2012-08-25T02:52:04 < zyp> so now I have both
2012-08-25T02:52:19 < Laurenceb_> ah
2012-08-25T02:53:06 < emeb> what pin does SWO come out on?
2012-08-25T02:53:19 < zyp> JTDO
2012-08-25T02:53:24 < emeb> Nice.
2012-08-25T02:53:59 < emeb> I suppose I could do a custom board with 20-pin 0.1" JTAG + 10-pin mini JTAG + 6-pin SWD.
2012-08-25T02:54:23 < emeb> need to source the mini-10 connectors though - DK says no stock.
2012-08-25T02:54:24 < zyp> if you already have the 20-pin, you could just use that
2012-08-25T02:54:37 < emeb> I've got a bmpm - no 20-pin on it.
2012-08-25T02:54:47 < Laurenceb_> i tried to make one with a maple
2012-08-25T02:54:55 < zyp> http://bin.jvnv.net/f/9kGPA.JPG <- like I used to do before
2012-08-25T02:55:00 < zyp> just in the opposite direction
2012-08-25T02:55:14 < Laurenceb_> but it failed as i cant get libopencm3 code to start
2012-08-25T02:55:27 < karlp> (I just stuck the same 6 pin header as the discovery boards on mine)
2012-08-25T02:55:58 < emeb> crude but effective. I've done that too on my first STM32 board w/ 20-pin JTAG.
2012-08-25T02:56:08 < karlp> mini10 was sexy, but not cheap, and not floating around the lab already
2012-08-25T02:56:20 < Laurenceb_> oh _thats_ what the unused pins on the F4disvoery are

2012-08-25T02:57:24 < Laurenceb_> i thought they were to rest it on

2012-08-25T02:58:01 < zyp> dual purpose!
2012-08-25T02:58:02 < emeb> so they can short out on other stuff you've got laying on the bench.
2012-08-25T02:58:35 < Laurenceb_> lol
2012-08-25T02:58:38 < emeb> zyp: where'd the little 20->10 JTAG adapter come from?
2012-08-25T02:58:45 < zyp> uh
2012-08-25T02:58:53 < dongs> zyp, nice armjtag to cortex debug board.
2012-08-25T02:58:58 < karlp> zyp: what's that baseboard under your mbed?
2012-08-25T02:59:02 < zyp> dongs, you've said so before

2012-08-25T02:59:29 < dongs> except i fucked up the cortex header direction :)
2012-08-25T02:59:49 < Laurenceb_> i just stick a 10pin header on there
2012-08-25T02:59:54 < emeb> Just pop the IDC cable out & reroute it.
2012-08-25T02:59:57 < Laurenceb_> s.10/20
2012-08-25T03:00:04 < dongs> i mean, just orientation
2012-08-25T03:00:07 < dongs> electrically its fine
2012-08-25T03:00:17 < dongs> i'd preferred the 10pin idc cable facing out
2012-08-25T03:00:26 < dongs> but its not mission critical or even annoying since i can just bend it like in the pic.
2012-08-25T03:00:36 < zyp> dongs, got any leftovers of those? emeb seems to want one :p
2012-08-25T03:00:53 < dongs> zyp, i cant order one pcb of anything so i always have bags of prototype ones
2012-08-25T03:00:59 < emeb> would be handy.
2012-08-25T03:01:30 < zyp> that's what I figured
2012-08-25T03:02:02 < karlp> zyp: the one with the ethernet, usb A and usb B?
2012-08-25T03:02:24 < emeb> But really all I need is to source the mini-10 connector. Anyone got a vendor? DK seems to be out.
2012-08-25T03:02:42 < emeb> (of the samtec ones)
2012-08-25T03:03:07 < zyp> karlp, http://www.coolcomponents.co.uk/catalog/mbed-lpc1768-workshop-development-board-p-608.html <- old version of this
2012-08-25T03:04:53 < zyp> emeb, http://www.digikey.no/product-detail/en/20021521-00010T1LF/609-4054-ND/2414951 <- I'm using these
2012-08-25T03:05:00 < zyp> I prefer them shrouded
2012-08-25T03:05:08 < emeb> zyp: ty
2012-08-25T03:05:25 < emeb> was just narrowing the search...
2012-08-25T03:05:30 < dongs> emeb: you mean the header? or idc
2012-08-25T03:05:38 < dongs> S9012E-05-ND is that out?
2012-08-25T03:05:47 < dongs> i see 11k in stock
2012-08-25T03:06:04 < zyp> not a huge price difference
2012-08-25T03:06:10 < emeb> dongs: that's there
2012-08-25T03:06:27 < dongs> shrouded, nice.
2012-08-25T03:06:34 < zyp> and unless you're short on space, get a shrouded one
2012-08-25T03:06:35 < emeb> funny - the unshrouded is more expensive in small qty
2012-08-25T03:06:39 < dongs> yeah
2012-08-25T03:06:40 < dongs> what the fuck
2012-08-25T03:06:50 < dongs> i thought i had the cheapest connectors urls
2012-08-25T03:06:53 < dongs> beaten by zyp, again
2012-08-25T03:07:21 < emeb> Time to place an order and start an adapter design.
2012-08-25T03:07:44 < emeb> add that to my next STM32 board (along with the 6-pin 0.1" header)
2012-08-25T03:08:09 < zyp> dongs, when I got those ESCs from you I put all the antistatic bags into my luggage when I went for christmas vacation, when I arrived I had lots of bent pins
2012-08-25T03:08:41 < zyp> not worse than I got them back into place, but still
2012-08-25T03:08:42 < dongs> heh
2012-08-25T03:08:57 < dongs> right
2012-08-25T03:08:58 < zyp> takes nothing to bend them
2012-08-25T03:09:06 < dongs> btw did you see on newest revision of esc32, theres a spot for can driver
2012-08-25T03:09:12 < dongs> so no more haxing extdra trash
2012-08-25T03:09:16 < zyp> yeah, you mentioned that
2012-08-25T03:09:19 < zyp> sounds nice
2012-08-25T03:10:45 < zyp> I started hooking up an ESC to my F4 board here last weekend, but then I got derailed and continued working on the USB driver instead
2012-08-25T03:11:16 < zyp> removed the transceiver I had deadbugged on, going to try transceiverless instead
2012-08-25T03:12:00 < Laurenceb_> grumble
2012-08-25T03:12:05 < Laurenceb_> not enough timers
2012-08-25T03:12:48 < zyp> dongs, are the newest revision still using the same pins?
2012-08-25T03:13:15 < Laurenceb_> wish they could hook up to system timer
2012-08-25T03:13:30 < dongs> zyp, yes
2012-08-25T03:13:34 < dongs> pinout didnt change
2012-08-25T03:13:42 < zyp> good
2012-08-25T03:13:50 < dongs> except eurofags got a hold of the design files
2012-08-25T03:13:54 < dongs> and now it costs 4x of what it should ahve been
2012-08-25T03:14:10 < zyp> heh
2012-08-25T03:15:05 < emeb> looks like the mating IDC connector: http://www.digikey.com/product-detail/en/20021444-00010T1LF/609-4055-ND/2414952
2012-08-25T03:15:11 < dongs> oh, dont get that
2012-08-25T03:15:13 < zyp> well, worst case I do my own hardware once I have a working firmware
2012-08-25T03:15:18 < dongs> http://microcontrollershop.com/product_info.php?products_id=4517
2012-08-25T03:15:32 < dongs> just get assembled cable for mess :)
2012-08-25T03:15:34 < dongs> er, less
2012-08-25T03:15:42 < zyp> agreed, that's what I also did
2012-08-25T03:15:48 < dongs> digikey wants like $10 for that same cable!
2012-08-25T03:15:49 < emeb> Nice - Get a couple and hack 'em in half
2012-08-25T03:15:51 < dongs> i couldnt fucking believe it
2012-08-25T03:16:06 < dongs> no, just put the same 10pin header on both target and jtag adapter
2012-08-25T03:16:09 < dongs> and just use the cable as intended
2012-08-25T03:16:41 < emeb> ideally, yes.
2012-08-25T03:16:57 < emeb> in reality I've got boards with Discovery-style SWD headers.
2012-08-25T03:17:18 < emeb> So hacking up cheap cables is an attractive alternative.
2012-08-25T03:18:06 < emeb> Haven't been on the uCshop for a while - need to browse around and see what other fun stuff they've got.
2012-08-25T03:18:23 < dongs> i picked up a nice vacuum pen there
2012-08-25T03:18:33 < zyp> using the end of a ribbon cable directly rather than through an IDC connector isn't really very attractive
2012-08-25T03:18:35 < dongs> havent had a bridge on hand-placed qfp48's for a while now
2012-08-25T03:18:38 < Laurenceb_> is system timer 24 bit?
2012-08-25T03:18:43 < dongs> sytick? yes
2012-08-25T03:18:54 < dongs> 24niggabits
2012-08-25T03:19:26 < zyp> Laurenceb_, systick timer is internal in the cortex core, that's why it's completely unrelated to the peripheral timers
2012-08-25T03:19:28 < emeb> zyp: yeah - those are pretty fine-gauge wires. But, it gets me going fast, and with proper strain relief it should be OK.
2012-08-25T03:19:55 < zyp> the only proper strain relief is IDC connectors.
2012-08-25T03:20:36 < emeb> Oh, I'd imagine a couple layers of heatshrink would do the trick.
2012-08-25T03:21:26 < dongs> before i made hte pcb I did exactly that
2012-08-25T03:21:40 < dongs> cut apart the idc and soldered directly into arm-jtag shrouded header.
2012-08-25T03:21:43 < dongs> was fucking ghetto.
2012-08-25T03:21:50 < dongs> relpaced it before it broke off.
2012-08-25T03:22:04 < emeb> ghetto is just what I was thinking...
2012-08-25T03:22:31 < zyp> I soldered the end of an IDC cable directly to a maple board

2012-08-25T03:23:44 < dongs> there are jlink clones but fucking segger now raped them
2012-08-25T03:23:46 < zyp> ugly as hell
2012-08-25T03:23:56 < Laurenceb_> ah yes
2012-08-25T03:24:04 < Laurenceb_> i can use systick
2012-08-25T03:24:09 < dongs> nice dongcopter there
2012-08-25T03:24:10 < dongs> Laurenceb_: for what.
2012-08-25T03:24:20 < Laurenceb_> for orthogonalising my pwm
2012-08-25T03:24:28 < zyp> dongs, it was my first :)
2012-08-25T03:24:32 < dongs> lost me at "orthogonalising"
2012-08-25T03:24:33 < emeb> looks like one of the props is busted
2012-08-25T03:24:45 < dongs> emeb: no its new advanced single bladeprops
2012-08-25T03:24:52 < zyp> emeb, yes, I had just been out crashing, was on my way in
2012-08-25T03:24:57 < emeb> no balance problems there...
2012-08-25T03:25:26 < dongs> emeb: single blade prop is more efficient than 2,3blade
2012-08-25T03:25:38 < Laurenceb_> ...
2012-08-25T03:25:41 < emeb> just a littler harder on the motor bearings.
2012-08-25T03:25:44 < Laurenceb_> seriously single blade?
2012-08-25T03:25:49 < dongs> emeb, thy  can be balanced
2012-08-25T03:25:50 < dongs> Laurenceb_: yea
2012-08-25T03:25:52 < Laurenceb_> with counterweight?
2012-08-25T03:25:54 < Laurenceb_> photos?

2012-08-25T03:26:27 < emeb> who knew Ericsson made quadcopters?
2012-08-25T03:26:40 < Laurenceb_> interesting

2012-08-25T03:26:44 < zyp> :)
2012-08-25T03:27:13 < zyp> emeb, oh, that was before I started working there
2012-08-25T03:27:34 < emeb> They were so impressed with what they saw out the window...
2012-08-25T03:27:36 < zyp> I used to live next to it
2012-08-25T03:27:47 < zyp> the uni is also right next to it
2012-08-25T03:28:03 < emeb> so they can get lots of cheap intern labor?
2012-08-25T03:28:11 < zyp> ha :p
2012-08-25T03:28:33 < BrainDamage> dongs: I think delayextreme sells a jlink clone
2012-08-25T03:28:44 < zyp> it was nice the first month I was working, just had to cross the road
2012-08-25T03:28:47 < dongs> so does wayengineer, but they're useless with latest jlink software
2012-08-25T03:29:08 < dongs> ive got 2 and they're collecting dust
2012-08-25T03:29:11 < dongs> luckily my jlinkedu still works
2012-08-25T03:29:22 < emeb> zyp: and now you moved further away. That's how it always works.
2012-08-25T03:29:26 < zyp> yep
2012-08-25T03:29:33 < zyp> half an hour by foot now
2012-08-25T03:29:46 < zyp> so I always drive

2012-08-25T03:31:28 < dongs> ulink2? I think only uvision/keil supports it?
2012-08-25T03:31:45 < zyp> I didn't even have time to use my jlink clone with anything before I bricked it
2012-08-25T03:31:47 < dongs> which is nice since thats what I use, and jlink integration with keil was kinda annoying
2012-08-25T03:36:46 < zyp> if I'm hoping to get anything done tomorrow I should get some sleep now
2012-08-25T03:37:14 < Laurenceb_> hmm i can syncronise systik to my timers
2012-08-25T03:37:26 < Laurenceb_> then put my pwm fudge code at the start
2012-08-25T03:37:41 < Laurenceb_> and its only one interrupt that needs to be max priority

2012-08-25T14:23:04 < cjbaird> WEll, the text <7kB anyway. Haven't seen what the final BSS or heap will be like. Another reason nanojpeg was unsutiable was its sucking up 512kB of ram.
2012-08-25T14:30:05 < jpa-> it's not "you have to give all ownership to me" license, just that they want to get a copy
2012-08-25T14:30:53 < jpa-> but yeah, the RAM usage is probably more of a trouble..
2012-08-25T14:36:24 < cjbaird> he gets a copy.. that he can do anything with. "But what if I don't feel like sharing that arithmetic encoder addition..?"
2012-08-25T14:37:43 < jpa-> so it's back to the usual copyleft vs. public domain war
2012-08-25T14:39:13 < jpa-> just be happy that someone shared, why wouldn't you share also?
2012-08-25T14:41:39 < cjbaird> Like 'beerware', it's another braggadocio licence that has the potential to be more fucked-up than the GPL when it comes to the conditions placed on derivative works..
2012-08-25T14:41:41 < dongs> lol.
2012-08-25T14:42:03 < jpa-> true, it's a bit dull license
2012-08-25T14:42:18 < jpa-> though i don't think it has any restrictions on derivative works
2012-08-25T14:42:19 < dongs> 3 other japs are here to watch total recall
2012-08-25T14:42:50 < cjbaird> I'll be a jpegdecoderboy.. I can bung all the code into a single file which is a big help, too.
2012-08-25T14:42:51 < jpa-> and you could probably even write "This was the original license, my new license is:" at the top; a bit like how BSD license works
2012-08-25T14:42:55 < dongs> so I centered myself in the cinema
2012-08-25T14:46:20 < cjbaird> ..you travelled 200kms to watch Total Recall?
2012-08-25T14:46:55 < dongs> among other things, yes

2012-08-25T14:48:52 < jpa-> gah; reinventing the pic programmer yet again? :D

2012-08-26T00:36:21  * Laurenceb_ has a deranged way of doing orthogonal pwm
2012-08-26T00:36:42 < Laurenceb_> using gating of some of the timers with spare output compare channels on the others
2012-08-26T00:36:55 < Laurenceb_> it is possible to get orthogonal pwm frequencies
2012-08-26T00:37:05 < Laurenceb_> but its impossible to work out and the maths is nutty
2012-08-26T00:37:26 < Laurenceb_> ive got an script running to search for the possible setups that work
2012-08-26T00:37:39 < Laurenceb_> but it gets exponentially more complex as i add more timers
2012-08-26T00:37:53 < Laurenceb_> 6 timers has been running for 5 hours now
2012-08-26T00:39:27 < Laurenceb_> im sure there is a way to do this properly... using set theory or ... something
2012-08-26T00:40:05 < Erlkoenig> discrete mathematics. it solves everything. :P
2012-08-26T00:41:01 < Laurenceb_> ive just written a few line octave script
2012-08-26T00:41:15 < Laurenceb_> its solved up to 6 timers on an F4 now without issue
2012-08-26T00:41:39 < Laurenceb_> spaghetti gating to get just the right periods on each timer
2012-08-26T00:42:12 < Laurenceb_> so that the frequencies are othogonal and at constant phase to the adc samples
2012-08-26T00:42:25 < Erlkoenig> what exactly are you going to use that modulation stuff for?
2012-08-26T00:42:30 < Laurenceb_> that was i can run the adc at full speed and have some simple integer maths to downconvert
2012-08-26T00:42:38 < Laurenceb_> a cheap spectrometer
2012-08-26T00:42:52 < Laurenceb_> using frequency division modulation of an led array
2012-08-26T00:43:35 < Erlkoenig> weird.
2012-08-26T00:43:43 < Laurenceb_> i am
2012-08-26T00:44:19 < Laurenceb_> i discovered the hard way that if the frequencies arent both orthogonal to one another and at constant phase to the adc there is wripple
2012-08-26T00:44:24 < Laurenceb_> -w
2012-08-26T00:44:59 < Laurenceb_> due to interference and harmonics in the signal
2012-08-26T00:45:05 < Erlkoenig> what does "two frequencies are orthogonal" mean?
2012-08-26T00:45:16 < Laurenceb_> it doesnt for two frequencies
2012-08-26T00:45:20 < Erlkoenig> i.e. what's your scalar product here :D
2012-08-26T00:45:31 < Laurenceb_> only has meaning for n>=3 frequencies
2012-08-26T00:45:45 < Laurenceb_> where their delta frequency is constant
2012-08-26T00:45:58 < Laurenceb_> and 1/delta_f is the integration period
2012-08-26T00:46:10 < Laurenceb_> so you can resolve each frequency component with no crosstalk

2012-08-26T02:17:28 < cjbaird> Must get motivated to do the MPI-based mandelbrot generator. :)
2012-08-26T02:17:41 < qyx_> uhm, average ~5y old computer does it under 10m
2012-08-26T02:17:56 < BrainDamage> for compiling, I'd instead suggest running qemu in a modern machine
2012-08-26T02:18:05 < qyx_> with even less power required
2012-08-26T02:18:09 < BrainDamage> or simply cross compile
2012-08-26T02:18:13 < Laurenceb_> yeah
2012-08-26T02:18:15 < Laurenceb_> wtf
2012-08-26T02:18:18 < cjbaird> qyx_: average 5yo computer that you BUY OFF THE SHELF FROM WAL*MART
2012-08-26T02:18:47 < cjbaird> It uses about 13 watts at full tilt.
2012-08-26T02:18:51 < Laurenceb_> have you posted that on #raspberrypi
2012-08-26T02:19:08 < qyx_> cjbaird: you should make coll hotpluggable rack for them
2012-08-26T02:19:18 < qyx_> with live process migration!
2012-08-26T02:19:22 < qyx_> *cool
2012-08-26T02:19:38 < cjbaird> HAY GUISE I BOUGHT A COMPUTER FROM WAL*MART WHERE IS MY COMPUTER SCIENCE DEGREE?
2012-08-26T02:19:42 < BrainDamage> it might be a cheap way to test parallelization software
2012-08-26T02:19:50 < BrainDamage> accounting latencies, etc
2012-08-26T02:19:51 < cjbaird> qyx_: a pity that the OpenMOSIX project is dead.
2012-08-26T02:20:01 < cjbaird> Yep, all that kind of fun stuff.
2012-08-26T02:20:17 < qyx_> some time ago i tried it
2012-08-26T02:20:23 < qyx_> i think it had some successor
2012-08-26T02:20:29 < qyx_> openmpi or something like that
2012-08-26T02:20:59 < qyx_> no, openlpi
2012-08-26T02:20:59 < cjbaird> It was probably the most available process-migration project on Linux. Unfortunately it was too tied to x86.
2012-08-26T02:21:04 < qyx_> hm, no
2012-08-26T02:21:05 < zyp> I remember testing kerrighed once
2012-08-26T02:22:01 < qyx_> that mpi reminds me some of the quadrics/qsnet network cards lying around
2012-08-26T02:22:12 < qyx_> i can't find any reasonable usage for them
2012-08-26T02:22:17 < zyp> turned into me and my housemate netbooting every free computer we had into the cluster because it was cool to have a lot of cpus and memory show up in top
2012-08-26T02:22:36 < cjbaird> zyp: done that :)
2012-08-26T02:26:13 < zyp> though, that was only a couple of dual cores and a couple of single cores, and not really a whole lot of memory, so my current workstation with a quadcore+HT and 32G ram would probably look «way cooler» anyway
2012-08-26T02:26:25 < zyp> not to mention dwarf the cluster when it comes to performance
2012-08-26T02:29:40 < cjbaird> I used to know Martin Pool when I was living in Brisbane, and at the first HUMBUG (Linux LAN) meet after he first released distcc, half a dozen of the Linux boxen did a group kernel compile. :)
2012-08-26T02:31:06 < BrainDamage> I guess that's the linux equivalent of circling across a bonfire
2012-08-26T02:31:19 < BrainDamage> sorry, I'm in a trolling mood tonight
2012-08-26T02:31:22 < zyp> I've never had much interest for distcc, my fastest computer has traditionally been much faster than all the other I have available
2012-08-26T02:31:42 < zyp> add in network overhead, and then there is not really much gain from using it
2012-08-26T02:31:45 < cjbaird> http://i.imgur.com/ukmQb.jpg .. My machine's the one with the black monitor (using a Sony NeWS3400 as a stand..) Not me standing next to it, though.
2012-08-26T02:31:59 < BrainDamage> same for me zyp
2012-08-26T02:32:24 < BrainDamage> and leaving the older machines running would've been such a waste in power that wouldn't been worth it
2012-08-26T02:33:49 < cjbaird> Most of those machines are 486.. taken in 1995, I think. http://i.imgur.com/x75CR.jpg .. "Oh, a LAN, huh? What gaems did you play??" "Games..?"

2012-08-26T03:56:53 < emeb_mac> you know, some IRC conversations are really difficult to catch up with if you weren't there at the start.
2012-08-26T03:58:57 < zyp> some aren't worth catching up with
2012-08-26T04:01:15 < zyp> short story goes like this: cjbaird used the term SSBBW in a story, causing people to start wondering what SSBBW meant, derailing the whole conversation into one about googling pictures of fat ladies
2012-08-26T04:01:34 < emeb_mac> urban dictionary gives a sufficiently detailed definition that I know I don't want to go there.
2012-08-26T04:01:46 < zyp> :)
2012-08-26T04:12:11 < cjbaird> A good old-fashioned IRC shock image trick...

2012-08-26T04:25:23 < emeb_mac> zzzzap!
2012-08-26T04:26:10  * emeb_mac reads the /. article on RaspPi USB problems...
2012-08-26T04:26:47 < zyp> which problems?
2012-08-26T04:27:08 < emeb_mac> http://hardware.slashdot.org/story/12/08/24/2228251/serious-problems-with-usb-and-ethernet-on-the-raspberry-pi
2012-08-26T04:27:40 < emeb_mac> Bad USB IP on the SoC, no documentation, driver code is a binary blob. etc. etc.
2012-08-26T04:28:15 < cjbaird> slowking.jpg
2012-08-26T04:29:10 < cjbaird> The USB, SD card, etc. issues were pretty-much realised the moment they first shipped..
2012-08-26T04:29:39 < emeb_mac> old news eh?
2012-08-26T04:29:47 < cjbaird> The power issue affected me-- the power supply for the cluster didn't go quite to plan..
2012-08-26T04:30:31 < zyp> ah, the ethernet chip is a combined usb hub and ethernet mac/phy, interesting
2012-08-26T04:31:56 < zyp> that expains why the usb ports are hooked to the ethernet chip, I was a bit curious about that when I looked at the board I got
2012-08-26T04:40:26 < zippe1> zyp: The pi is a very sad thing
2012-08-26T04:40:34 < zippe1> The chip … is not good.
2012-08-26T04:40:54 < zippe1> Basically, a bunch of bcm guys got Beagle Envy
2012-08-26T04:41:11 < zyp> can't say I'm surprised
2012-08-26T04:44:52 < cjbaird> It doesn't have anywhere near to the number of problems the Openmoko Neo had. :) (gps noise, gsm noise, microsd issues, ...)
2012-08-26T04:45:41 < cjbaird> The Neo's phone-side hardware pretty-much didn't work at all.

2012-08-26T20:44:11 < zyp> hmm, shorting vcc might have done the trick, either that or it magically started working by itself when I was testing with another identical board

2012-08-26T20:47:13 < Erlkoenig> i experimented with the RFM12 433 MHz RF module, and experienced obscure problems often about the module not willing to "boot", so i disconnected the module from Vcc and any capacitors upon starting the circuit, so it would see exactly 0V and then instantly 5V, which fixed all the problems...
2012-08-26T20:47:14 < Erlkoenig> i also thought i'd have enough load to discharge the caps, but measurements showed there were some 0.1V left for hours, keeping the module in some invalid state...

2012-08-26T20:48:39 < BrainDamage> hold down the reset with a rc circuit and a transistor

2012-08-26T20:51:24 < BrainDamage> maybe the nrf modules are sane(r)
2012-08-26T20:51:36 < BrainDamage> I used nrf24l01 and they are pretty decent
2012-08-26T20:51:40 < Erlkoenig> in some condition, the irq pin *should* go low (as documented), but just doesn't

2012-08-26T20:53:46 < BrainDamage> they are more expensive than the 2.4GHz conterparts
2012-08-26T20:54:03 < zyp> now I broke it again
2012-08-26T20:54:04 < BrainDamage> the problem with th 2.4GHz modules, is that stupid folded antenna for the sake of space
2012-08-26T20:54:22 < BrainDamage> so I end up physically cutting the module, and solder a sma connector on it

2012-08-26T20:54:32 <+Steffanx> On ebay there are 'long range' versions ...
2012-08-26T20:54:34 <+Steffanx> same pinout
2012-08-26T20:54:40 < BrainDamage> I did check, and they added the impedance matching circuit for 50Ohm
2012-08-26T20:54:44 < BrainDamage> so the sma is perfect
2012-08-26T20:54:55 < BrainDamage> yes, and cost 10$ for the nonamplified version
2012-08-26T20:54:59 < BrainDamage> and 20$ for the amplified
2012-08-26T20:55:11 <+Steffanx> 10$? < 5$
2012-08-26T20:55:15 < BrainDamage> link?
2012-08-26T20:55:42 <+Steffanx> Or do you mean one with SMA connector and no amplification?
2012-08-26T20:56:01 < BrainDamage> sma and no amplification
2012-08-26T20:56:10 <+Steffanx> Oh, ok
2012-08-26T20:56:34 < BrainDamage> adding a 2$ chinese wifi antenna is not a problem
2012-08-26T20:56:53 < BrainDamage> so the "mod" costs 2.3$ + 10 mins work
2012-08-26T20:57:03 < zyp> hmm, shorting vcc doesn't help at all now

2012-08-26T22:44:55 < Erlkoenig> i wanted to measure a circuit powered by USB using a DSO, so i connected the DSO's GND (which is connected to PE) to the USB's GND, which caused the isolation of the cable to melt. fortunately it was a bad cable with high resistance, so the scope wasn't harmed. anyway, easily touchable parts (USB-GND) shouldn't have a voltage != PE ...
2012-08-26T22:45:32 < emeb> That's some kind of ground loop you've got going there.
2012-08-26T22:46:51 < Erlkoenig> probably need a battery for the scope...
2012-08-26T22:47:21 < emeb> Or an isolation transformer
2012-08-26T22:47:58 < Steffanx_> or a power cable without PE? Which you can use for purposes like this?
2012-08-26T22:48:04 < Erlkoenig> don't these cause additional security risks because the scope isn't earthe'd correctly then?
2012-08-26T22:48:42 < emeb> Yeah - security risks. Without a grounded power cable, haxors can pwn your server.

2012-08-26T22:49:50 < Erlkoenig> disconnecting a device from PE which is supposed to be grounded doesn't sound like too much of a good idea

2012-08-26T23:02:16 < BrainDamage> and measure if there's potential
2012-08-26T23:02:52 < Erlkoenig> probably there will
2012-08-26T23:03:02 < Erlkoenig> but this way i can't measure anything :D
2012-08-26T23:03:28 < BrainDamage> if the usb voltages are referred to that gnd
2012-08-26T23:03:36 < BrainDamage> you'll only have to add / subtract that value
2012-08-26T23:03:40 < emeb> Best thing is to make sure the PE of the scope is connected to the same PE as the DUT.
2012-08-26T23:04:22 < emeb> If there's a Vdiff then you've got bigger problems to solve before dealing with the scope measurements.
2012-08-26T23:04:26 < Erlkoenig> ah you mean substract the USB-GND's potential from the values measured relative to PE?

2012-08-26T23:04:55 < Erlkoenig> yeah, they are surely connected to the same PE
2012-08-26T23:05:02 < Erlkoenig> but the USB-GND seems to be different from PE
2012-08-26T23:05:17 < emeb> Then there's a power supply problem in your USB device.
2012-08-26T23:06:08 < Erlkoenig> also i fear that Vdiff = PE - "USB-GND"   is not constant but some sort of ripple because of the switching power supply
2012-08-26T23:06:50 < emeb> Yeah - and if it's got sufficient current to melt cables, that's a big problem.
2012-08-26T23:07:33 < Erlkoenig> it didn't melt the copper, only the rubber isolation ;)
2012-08-26T23:07:46 < emeb> regardless...
2012-08-26T23:08:09 < Erlkoenig> the computer is a notebook... that means the problem is probably in the notebook-PSU?
2012-08-26T23:09:51 < emeb> Hard to say - external AC brick/wall-wart perhaps, or possibly even in the internal switchers.

2012-08-26T23:11:49 < emeb> But, you can try running the laptop off battery - that should eliminate the ground loop through PE.
2012-08-26T23:12:14 < Erlkoenig> Ethernet cables don't carry any GND/Ground, because of differential signaling and tranformators, right?
2012-08-26T23:12:29 < emeb> Yeah - Ethernet should be isolated.

2012-08-27T00:06:44 < Laurenceb__> doh
2012-08-27T00:06:53 -!- Laurenceb__ is now known as Laurenceb_
2012-08-27T00:07:06 < Laurenceb_> grrr
2012-08-27T00:07:17 < Laurenceb_> i cant find a way to make orthogonal pwm
2012-08-27T00:07:52 < zyp> that's probably why people aren't already doing it
2012-08-27T00:11:15 < Laurenceb_> wait wtf
2012-08-27T00:11:29 < Laurenceb_> im setting prescaler to 16 and getting 4.5mhz clk
2012-08-27T00:13:28 < Laurenceb_> the std lib code just does   TIMx->PSC = TIM_TimeBaseInitStruct->TIM_Prescaler;
2012-08-27T00:13:32 < Laurenceb_> so wtf
2012-08-27T00:16:22 < Laurenceb_> i havent set the prescaler?
2012-08-27T00:18:06 < Laurenceb_> hmm
2012-08-27T00:18:16 < Laurenceb_> this may explain my issues with uSD cards
2012-08-27T00:22:26 < Laurenceb_> how do i set prescaler - is there a perif function?
2012-08-27T00:25:17 < Steffanx_> probably, yes
2012-08-27T00:29:09 < Laurenceb_> wtf ST
2012-08-27T00:29:11 < Laurenceb_>  const uint32_t SystemFrequency_APB1Clk = (SYSCLK_FREQ_72MHz/2);  /*!< APB Peripheral bus 1 (low)  speed   */
2012-08-27T00:29:23 < Laurenceb_> in CMSIS_CM3
2012-08-27T00:29:31 < Laurenceb_> but nowhere does it actually set it
2012-08-27T00:29:36 < Laurenceb_> mental
2012-08-27T00:30:37 < Steffanx_> "= (SYSCLK_FREQ_72MHz/2)" isn't enough for you?
2012-08-27T00:30:58 < Laurenceb_> erm it has to set it in systeminit
2012-08-27T00:31:09 < Laurenceb_> everything else is setup
2012-08-27T00:31:32 < Laurenceb_> no wonder spi2 is breaking
2012-08-27T00:33:41 < zyp> huh?
2012-08-27T00:34:12 < Laurenceb_> the cmsis_cm3 systeminit code doesnt set the prescaler
2012-08-27T00:34:33 < Laurenceb_> even tho it sets SystemFrequency_APB1Clk
2012-08-27T00:34:58 < zyp> you're just misreading/misunderstanding something
2012-08-27T00:35:46 < Laurenceb_> do i have to set the prescaler myself then?
2012-08-27T00:35:56 < zyp> what prescaler where?
2012-08-27T00:36:25 < Laurenceb_> between AHB and APB1
2012-08-27T00:36:56 < zyp> that should be done by the startup code, at the same time it's enabling PLL and stuff like that
2012-08-27T00:37:22 < Laurenceb_> thats my point
2012-08-27T00:37:23 < Laurenceb_> its not
2012-08-27T00:38:09 < Steffanx_> Sure?
2012-08-27T00:38:16 < zyp> are you sure? it goes into RCC_CFGR along with the other sysclock options
2012-08-27T00:39:04 < zyp> if you want to verify you could just dump that in the debugger and see
2012-08-27T00:39:52 < Laurenceb_> oh wait
2012-08-27T00:40:14 < Laurenceb_> i think i rewrote that function so you could #define the xternal xtal frequency
2012-08-27T00:40:22 < Laurenceb_> i probably broke something
2012-08-27T00:40:27 < Steffanx_> :D :D
2012-08-27T00:40:29 < zyp> oh
2012-08-27T00:40:40 < Laurenceb_> :P
2012-08-27T00:40:49 < zyp> well, if you are running APB1 at 72 MHz, you could get lots of problems
2012-08-27T00:41:02 < Laurenceb_> suprisingly the timers all work fine
2012-08-27T00:41:14 < Laurenceb_> but this would explain why my uSD card breaks
2012-08-27T00:41:21 < zyp> yes, it could
2012-08-27T00:41:52 < Laurenceb_> - i got confused about the spi prescaler and didnt realise what the APB1 clk was at the time
2012-08-27T00:42:04 < Laurenceb_> but i scoped the spi and the spi clk was correct
2012-08-27T00:42:24 < Laurenceb_> but the peripheral was still overclocked, which could explain why it somethings has glitches
2012-08-27T00:42:45 < Laurenceb_> like returning intermittent 0x02

2012-08-27T01:09:09 < Laurenceb_> will have to take a look
2012-08-27T01:10:00 < zyp> oh, wait
2012-08-27T01:10:16 < zyp> the timers are still running at 72 MHz even if the bus are 36 MHz
2012-08-27T01:10:50 < Laurenceb_> wtf
2012-08-27T01:11:15 < Laurenceb_> oh
2012-08-27T01:11:15 < zyp> have a look at the clock tree again
2012-08-27T01:11:26 < zyp> there is a multiplier in front of the timer input clock
2012-08-27T01:11:35 < Erlkoenig> the clock tree documentation is... unhelpful
2012-08-27T01:11:43 < Laurenceb_> oh "else x2"
2012-08-27T01:12:10 < Erlkoenig> clocks in the tree figure have different names than in the rest of the docs...
2012-08-27T01:12:12 < zyp> yes, so if the APB prescaler is enabled, timer clock will be doubled
2012-08-27T01:12:28 < Laurenceb_> well... on the +ive side that explains why it works and means OFDMworks
2012-08-27T01:12:40 < Laurenceb_> on the -ive side it doesnt explain my spi2 issues

2012-08-27T02:13:04 < Erlkoenig> don't be sad, the MSDNAA download servers are worse... around 70% or something, the downloads crash, you can resume, but the files are *always* corrupt. also, you can't use a real downlaod manger, because the files are encrypted, and mircrosoft's download manager & decrypter wants to download them themselves

2012-08-27T02:18:20 < Erlkoenig> sometimes one unfortunately needs windows
2012-08-27T02:18:41 < Erlkoenig> and having visual studio might come handy sometimes too

2012-08-27T02:21:27 < qyx_> "for free" actually means for (and only for
2012-08-27T02:21:35 < qyx_> running their development environments
2012-08-27T02:21:45 < Erlkoenig> when i started with stm32, it was very nice i could just use the free version of atollic studio and get the "hello worlds" running without the hassle of setting up a free linux-based toolchain...

2012-08-27T02:22:45 < emeb> Erlkoenig: Atollic still has a free version. Size limited though...
2012-08-27T02:23:03 < Erlkoenig> yeah i know, but it's windows-only ;)
2012-08-27T02:23:25 < emeb> Ah - there was a linux version of Atollic?
2012-08-27T02:23:27 < Erlkoenig> so in that case having windows had some advantage :)

2012-08-27T02:27:13 < Erlkoenig> yeah i have a free toolchain now too, but it's nice to at least get a LED blinking without hours of fiddling *g*
2012-08-27T02:28:16 < Erlkoenig> btw, what startup code and linker script do you use for the STM32F4? self-written? i copied the one from atollic (which originally seems to come from ST) and it works with "normal" arm-gcc
2012-08-27T02:29:10 < emeb> Yeah - grabbed the startup files & linker script out of the ST examples.
2012-08-27T02:29:33 < emeb> Needed some tweaking for my clock hardware, but otherwise works fine.
2012-08-27T02:31:41 < Erlkoenig> uhm, the examples contain code for various proprietary toolchains... which one did you choose?
2012-08-27T02:32:55 < emeb> my startup_stm32f4xx.s says "STM32F4xx Devices vector table for RIDE7 toolchain."
2012-08-27T02:33:35 < emeb> system_stm32f4xx.c looks like it's generic
2012-08-27T02:34:16 < emeb> linker script has 'no distinguishing features'
2012-08-27T02:35:04 < Erlkoenig> ah, the ride7 one looks similar to the true studio one, but e.g. the IAR one is completely different
2012-08-27T02:35:23 < emeb> Oh yeah - Ride and Atollic are both GCC based.
2012-08-27T02:35:35 < emeb> IAR, Keil, etc are proprietary.
2012-08-27T02:35:54 < Erlkoenig> aah that's why
2012-08-27T02:36:24 < Erlkoenig> is your linker script the "stm32_flash.ld" one?
2012-08-27T02:36:50 < Erlkoenig> and happens to be suitable for the F4 Discovery?
2012-08-27T02:37:09 < emeb> Yep
2012-08-27T02:37:50 < Erlkoenig> there's a bug in that one, which occurs sometimes when using C++... described it here: http://comments.gmane.org/gmane.comp.gnu.binutils/57524
2012-08-27T02:39:37 < emeb> wonder if it's in the script or in ld?
2012-08-27T02:40:14 < Erlkoenig> i think it's a 'feature' of LD, and the script doesn't "know" about it...
2012-08-27T02:40:39 < emeb> could be version dependent - I'm not on Windows w/ the launchpad.net toolchain.
2012-08-27T02:41:08 < Erlkoenig> i think it appeared on linux, and with the true studio version as well
2012-08-27T02:41:45 < emeb> Guess I'd have to look at the map & dumps to know if it's a problem for me.
2012-08-27T02:41:46 < Erlkoenig> if you click "(Continue reading)" you see a link to a testcase ;)
2012-08-27T02:42:01 < emeb> yeah - already there.
2012-08-27T02:43:23 < emeb> Any follow-up on that?
2012-08-27T02:43:46 < Erlkoenig> well i found out myself what the problem was, and wrote an answer
2012-08-27T02:44:11 < Erlkoenig> just a tiny modification to the .ld script fixes it

2012-08-27T02:52:00 < emeb> Hmm - doesn't look the same as mine.
2012-08-27T02:52:28 < emeb> your data section has no "arguments"
2012-08-27T02:52:52 < emeb> mine says :     .data : AT ( _sidata )
2012-08-27T02:52:52 < emeb> with _sidata defined prior as .
2012-08-27T02:53:55 < Erlkoenig> uuuh

2012-08-27T02:54:27 < Erlkoenig> oh
2012-08-27T02:54:33 < emeb> Here's mine: http://pastebin.com/5nG2L2my
2012-08-27T02:54:48 < Erlkoenig> that's an alternative fix, which i also tried and works, but i thought it would be less clean
2012-08-27T02:55:13 < emeb> Ah - well, it's been a while since I set this up. No idea where that came from...
2012-08-27T02:55:36 < Erlkoenig> nooooooo
2012-08-27T02:55:48 < Erlkoenig> you got your code from the newer ST Library
2012-08-27T02:56:04 < Erlkoenig> my code comes from the True Studio Template
2012-08-27T02:56:15 < Erlkoenig> which seems to use the older example code from ST, including that bug
2012-08-27T02:56:40 < Erlkoenig> that explains why noone else fell for that
2012-08-27T02:56:55 < emeb> I got my code from "STM32F4-Discovery_FW_V1.1.0" back in October '11
2012-08-27T02:57:01 < Erlkoenig> well at least now i know something about linker scripts -.-
2012-08-27T02:57:43 < emeb> Yay! Lets hear it for good revision control on the ST website.
2012-08-27T02:58:27 < Erlkoenig> grrr...
2012-08-27T02:58:41 < Erlkoenig> well uhm i'm going to bed now i think...
2012-08-27T02:58:52 < Erlkoenig> good night or whatever time of the day you have ;-)

2012-08-28T14:19:02 <+Steffanx> jpa- you use an STM32L[something] didn't you? How 'low power' it really is?
2012-08-28T14:19:03 < nopcode_> and many people have one for that reason

2012-08-28T14:21:13 < karlp> Steffanx: how low are you hoping for an answer?
2012-08-28T14:21:22 < karlp> (get the 32L discovery, it's awesome)
2012-08-28T14:21:33 < jpa-> Steffanx: 5-10mA when running (moderate set of peripherals), very low when sleeping
2012-08-28T14:21:41 <+Steffanx> HJmmpf :P
2012-08-28T14:21:57 < jpa-> ah, and that figure is at 24MHz
2012-08-28T14:22:04 < jpa-> so not very low power in operation
2012-08-28T14:22:23 < karlp> the latest datasheet has lots of figures on power consumption at different speeds and modes.
2012-08-28T14:22:25 <+Steffanx> karlp, just wonder how low it really gets.. datasheet vs jpa/user tests
2012-08-28T14:22:59 < jpa-> seems to agree quite well with the datasheet, actually
2012-08-28T14:23:26 < jpa-> at first i was a bit confused because of high power usage, but it turned out I had a few bugs elsewhere in the schematic
2012-08-28T14:23:53 < jpa-> USB takes a lot of power.. haven't bothered to figure out the sleep mode for it yet
2012-08-28T14:24:04 < jpa-> (a lot = 5mA or so)
2012-08-28T14:24:15 <+Steffanx> Yes, that's a lot for a low power device
2012-08-28T14:25:24 < jpa-> yeah, nothing like some of the low-power pics that take 0.1mA when running
2012-08-28T14:26:08 < zyp> does L1 have usb?
2012-08-28T14:26:11 < karlp> yep
2012-08-28T14:26:11 <+Steffanx> I'm not into PIC anyway
2012-08-28T14:26:14 < jpa-> zyp: it does, same as F1
2012-08-28T14:26:16 <+izua_> i think msp430 rule this area
2012-08-28T14:26:20 < zyp> ah
2012-08-28T14:26:32 < karlp> if you leave out the usb though, l1 is pretty low.
2012-08-28T14:26:35 < zyp> I was assuming it didn't, since L1discovery doesn't have a socket for it
2012-08-28T14:26:39 < jpa-> apparently stm32l151 goes down to 300µA if you clock it at 1MHz
2012-08-28T14:26:45 <+izua_> i recall some msp430 contraption with an lcd and two caps, which ran for quite some weeks
2012-08-28T14:26:47 < karlp> l1 discovery uses all the pins for the lcd
2012-08-28T14:27:03 <+Steffanx> What character is in between the 300 and A, jpa- ?
2012-08-28T14:27:08 < karlp> u
2012-08-28T14:27:09 < jpa-> micro
2012-08-28T14:27:16 < karlp> get a real terminal with a real charset man!
2012-08-28T14:27:43 <+izua_> karlp: (╯°□°）╯︵ ┻━┻
2012-08-28T14:27:58 < jpa-> 50uA at 65kHz :P
2012-08-28T14:28:05 < zyp> power usage really have to be viewed in relation to actions performed
2012-08-28T14:28:29 < karlp> izua_: fine, two chars missing, but that's because my font just doesn't have them all. (ff09 and fe35)
2012-08-28T14:29:16 < zyp> how much power it uses at a given clock rate is not very interesting, what matters is average power when you wake up, do stuff, then go back to sleep
2012-08-28T14:30:07 < jpa-> zyp: yeah.. though in some tasks, it's difficult to sleep very deep

2012-08-28T14:30:10 <+Steffanx> I see them all, so i don't know why i don't see that ? character
2012-08-28T14:30:35 < zyp> doing stuff slower means you are doing stuff for a longer duration of time
2012-08-28T14:30:35 <+Steffanx> anyway, not important :P
2012-08-28T14:30:37 < jpa-> and changing clock rate on the fly is quite a pain if you need to reconfigure the peripherals
2012-08-28T14:32:12 < zyp> jpa-, but that's very application specific
2012-08-28T14:32:25 < karlp> low power is fun
2012-08-28T14:32:32 < jpa-> hmm.. quite surprising, STM32F0 @ 24MHz without peripherals uses more power (7mA) than STM32L151 (5mA)
2012-08-28T14:32:54 < karlp> my current project is "low power" or will be,
2012-08-28T14:32:59 < karlp> battery operated at least.
2012-08-28T14:33:07 < karlp> but I'm just using an f100 at the moment.
2012-08-28T14:33:07 < zyp> jpa-, that's expected
2012-08-28T14:33:09 <+Steffanx> And it has to run for at least a year?
2012-08-28T14:33:20 < karlp> Steffanx: targetting 2 years on 2xaa
2012-08-28T14:33:26 <+Steffanx> Nice
2012-08-28T14:33:33 < karlp> but mostly just seeing how long I can go
2012-08-28T14:33:42 < karlp> using f100 because it's free from the box at work :)
2012-08-28T14:33:42 < zyp> jpa-, IIRC L1 uses some low power optimized process technology
2012-08-28T14:33:48 < karlp> but l1 is a pin compatible upgrade
2012-08-28T14:34:22 < karlp> will see how low I can get with just general ordinary power saving software first.
2012-08-28T14:34:28 < jpa-> yeah, and L1 has also adjustable core voltage.. F0 doesn't seem to, or atleast it is not exposed to user
2012-08-28T14:35:19 < karlp> L1 is nice, even if you don't need the power stuff. it's like a fixed f1.
2012-08-28T14:35:19 < jpa-> so i guess the only selling point of stm32f0 is that it is cheap
2012-08-28T14:35:29 < zyp> F0 uses less power than F1 because it's a simpler core, L1 uses less power than F1 because of process technology and stuff
2012-08-28T14:35:31 < karlp> all the newer periphs from teh f2/f4
2012-08-28T14:35:40 < zyp> that's why people are looking forward to the L0
2012-08-28T14:35:41 < zyp> :p
2012-08-28T14:35:41 < jpa-> karlp: indeed
2012-08-28T14:35:43 < karlp> l0 is coming out soon
2012-08-28T14:35:50 < jpa-> karlp: except F1-style USB
2012-08-28T14:36:08 < zyp> F1-style USB doesn't sound so bad
2012-08-28T14:36:15 < karlp> yeah, haven't used the usb on any of the devices, can't really speak about it
2012-08-28T14:36:51 < jpa-> yeah.. i'm not looking to develop my own USB drivers either, so it doesn't matter as long as chibios or something has support :P
2012-08-28T14:36:52 < zyp> I can't speak about the F1 USB, but it can't be worse than the OTG stuff :p
2012-08-28T14:37:38 < jpa-> apparently F4 full-speed usb is very complex
2012-08-28T14:37:56 < zyp> I'm currently in the process of cleaning up my USB code and splitting into generic and device specific stuff
2012-08-28T14:38:37 < zyp> I'm considering porting it to F1 when I'm done, as a proof of concept
2012-08-28T14:40:33 < zyp> the complexity of the USB controllers on F4 is not that bad, it's the quirks that are annoying

2012-08-28T15:28:14 < Laurenceb> but what if i want alt function on that pin?
2012-08-28T15:28:40 < jpa-> Laurenceb: dump your F1 and switch to a controller where you can select the AFIO :)
2012-08-28T15:29:03 < Erlkoenig> Laurenceb: i thought you want to *stop* it from using the pinß
2012-08-28T15:29:14 < Laurenceb> i do
2012-08-28T15:29:20 < Laurenceb> but i have other stuff on the pins
2012-08-28T15:29:24 < jpa-> it's a common problem in F1 that if you enable some peripheral, it hooks up the pin and you may not be able to use another alt function on the same pin
2012-08-28T15:29:27 < Laurenceb> using them as afio
2012-08-28T15:29:37 < Laurenceb> hmm
2012-08-28T15:29:41 < Erlkoenig> oh hm i only know about the F4

2012-08-28T15:30:27 < jpa-> (they have an AFIO register where you put an index of the peripheral whose alternate function you want to hook into the pin)
2012-08-28T15:31:04 < Erlkoenig> i wanted to suggest exactly that ;)
2012-08-28T15:31:15 < Laurenceb> i see
2012-08-28T15:31:35 < jpa-> Laurenceb: could you use a different timer, one where the pins don't conflict?

2012-08-28T19:01:53 < Laurenceb> im guessing dongs is now trolling about 20 channels with that
2012-08-28T19:02:00 < dongs> how did you know
2012-08-28T19:02:06 < Laurenceb> lol
2012-08-28T19:02:07 < dongs> retweeting it fucking everywhere
2012-08-28T19:02:35 < Laurenceb> "chilling with his hoes"
2012-08-28T19:07:09 <+Steffanx> karlp true, but still a little expensive for what it has to do
2012-08-28T19:07:31 <+Steffanx> Sleep, sleep, send, measure, sleep
2012-08-28T19:07:53 < Laurenceb> can you wake on comparator with everything sleeping?
2012-08-28T19:08:04 <+Steffanx> Yes
2012-08-28T19:08:08 <+Steffanx> * in stop mode
2012-08-28T19:08:09 < karlp> like I was saying this morning, I reckon you can get most of the mileage with f1 anyway.
2012-08-28T19:08:37 < karlp> or jsut suck it up. it's what, 4-5$?
2012-08-28T19:08:49 <+Steffanx> 4 euro at least
2012-08-28T19:08:58 < dongs> comparators on L1 kinda suck
2012-08-28T19:09:02 < dongs> also: its not pin compatible to F1
2012-08-28T19:09:12 <+Steffanx> What's wrong with them dongs ?
2012-08-28T19:09:13 < karlp> it's almost pin compatible
2012-08-28T19:09:24 < dongs> i thought it w as totally differfent pinout
2012-08-28T19:09:30 < dongs> I mgiht be thinking stm8s vs stm8l
2012-08-28T19:09:39 < karlp> there's a hardware migration guide that says it's only a couple of things
2012-08-28T19:09:40 < karlp> iirc
2012-08-28T19:09:46 < karlp> I might be remembering wrong too :)
2012-08-28T19:11:06 <+Steffanx> I only remember jpa- said something about the comparators, but don't remember what is complaint was
2012-08-28T19:11:23 -!- elektrinis [~circuit@82-135-241-134.static.zebra.lt] has quit [Quit: pokðt]
2012-08-28T19:15:52 <+Steffanx> Isn't F0 a better choice, lower price + less power usage
2012-08-28T19:15:59 <+Steffanx> When price matters :P
2012-08-28T19:18:26 < dongs> Steffanx: they're kinda fucked up
2012-08-28T19:18:32 < dongs> the source/compare shit
2012-08-28T19:18:35 < dongs> you can only route to some of htem
2012-08-28T19:18:40 < dongs> and some can only compare against avcc
2012-08-28T19:18:43 < dongs> or someshit like that
2012-08-28T19:19:03 <+Steffanx> Isn't that just something i should figure out before i do the design? :)
2012-08-28T19:19:19 < dongs> well, for example that stopped me from using stm32l for motor control
2012-08-28T19:19:31 < dongs> you couldnt get 3 phases into a comparator
2012-08-28T19:20:14 < dongs> <+Steffanx> Isn't that just something i should figure out before i do the design? :)
2012-08-28T19:20:17 < dongs> not if youre Laurenceb
2012-08-28T19:20:21 <+Steffanx> :P
2012-08-28T19:20:22 < dongs> you'll make it first, then wonder why shit doesnt work
2012-08-28T19:22:38 < jpa-> Steffanx: well they kind of totally suck :D
2012-08-28T19:22:56 <+Steffanx> ...
2012-08-28T19:23:20 < jpa-> two comparators that behave totally differently, and then they can be used together, but only in some very specific configurations..  aaaaand one of them cannot be used when ADC is in use
2012-08-28T19:23:39 < dongs> yeah, see ^
2012-08-28T19:25:39 <+Steffanx> It just has to look at the signal of a pir sensor ( amplified ) and wake up. Nothing special
2012-08-28T19:26:27 <+Steffanx> Say "hey something happened" ? zzzz/stop
2012-08-28T19:26:42 < jpa-> yeah, should work

2012-08-28T19:27:00 < jpa-> but please use the correct one of the comparators.. not the wrong one :)
2012-08-28T19:27:17 <+Steffanx> I will jpa-
2012-08-28T19:27:26 < jpa-> use COMP2, the retarded little brother has quirks that you'll never figure out beforehand

2012-08-28T19:29:20 <+Steffanx> The mess the arrow points at
2012-08-28T19:29:26 < Laurenceb> mess?!
2012-08-28T19:29:27 < dongs> looks like flux after cleaning
2012-08-28T19:29:32 < dongs> or rather
2012-08-28T19:29:37 < dongs> flux after soldering, but not washed
2012-08-28T19:29:41 <+Steffanx> :P
2012-08-28T19:30:14 <+Steffanx> And some resistors aren't aligned very well
2012-08-28T19:30:20 < dongs> i think if you compare with the shit this guy was pumping out

2012-08-28T19:32:12 <+Steffanx> "the retarded little brother has quirks that you'll never figure out beforehand" no blog about that jpa- ?
2012-08-28T19:34:51 < jpa-> i don't whine on my blog
2012-08-28T19:35:10 < jpa-> (even though it could sometimes be useful)
2012-08-28T19:35:12 <+Steffanx> Nor provide information for others
2012-08-28T19:35:42 < jpa-> yeah.. at one point i planned starting a section for that, but never bothered to write about trouble
2012-08-28T19:36:55 < emeb> those are some nasty looking soldering jobs.
2012-08-28T19:37:57 < jpa-> i never understood SMD could be so hard for someone :D
2012-08-28T19:38:32 <+Steffanx> t/lqfp is ok .. i'll stay away from qfn and stuff
2012-08-28T19:38:41 < emeb> if you get it stuck in your mind that you must use paste + stencil, and you can't do that well...
2012-08-28T19:39:08 < jpa-> though, a nice scrub with isopropyl alcohol and it could even look presentable
2012-08-28T19:39:32 < emeb> but not functional
2012-08-28T19:39:36 < jpa-> yeah

2012-08-28T19:40:26 <+Steffanx> That's ok
2012-08-28T19:40:27 < emeb> heh - no inductance issues there.

2012-08-28T19:47:39 < Erlkoenig> what to do against that?
2012-08-28T19:47:57 < emeb> Erlkoenig: put sunscreen on your face
2012-08-28T19:48:23 < Erlkoenig> he says that won't stop him
2012-08-28T19:48:31 < zyp> Erlkoenig, dogs are supposed to do that
2012-08-28T19:48:47 < zyp> get the leash and take him out for a walk
2012-08-28T19:48:56 < Erlkoenig> hmm i'm not so much into dogplay
2012-08-28T19:49:37 < zyp> so your friend is not a dog, and he still licks your face?
2012-08-28T19:49:46 < Erlkoenig> yes, somehow

2012-08-28T20:44:38 <+dekar> izua_, memory fragmentation is a major problem when using lua on the stm32
2012-08-28T20:44:56 <+izua_> how did that go?
2012-08-28T20:45:09 <+izua_> i messed with lua embedded in C some time ago, when you started telling me about stm32lua
2012-08-28T20:45:36 <+dekar> well you can't allocate an array of predefined size in lua
2012-08-28T20:45:47 <+dekar> you allocate an array and then grow it to your needs
2012-08-28T20:46:02 <+dekar> that causes a ton of fragmentation just growing it to 1kb

2012-08-28T20:46:28 <+izua_> how did you figure this out ?
2012-08-28T20:46:38 <+izua_> slow memory access later during execution?
2012-08-28T20:46:52 <+dekar> izua_, malloc(1500) fails
2012-08-28T20:46:59 <+dekar> speed is not a problem
2012-08-28T20:47:15 <+dekar> I have like 30kb of memory left, but can't allocate 1500bytes
2012-08-28T20:47:46 <+dekar> actually in some script a co-worker wrote you can't even allocate 500bytes anymore
2012-08-28T20:48:10 < emeb> yay - needs garbage collection.
2012-08-28T20:48:26 <+dekar> emeb, it has garbage collection, that's not the problem
2012-08-28T20:48:39 < emeb> defrag?
2012-08-28T20:48:50 <+dekar> yeah sram defray, called MMU :)
2012-08-28T20:48:55 <+dekar> *defrag
2012-08-28T20:49:00 < emeb> bleh.
2012-08-28T20:49:29 < TitanMKD> dekar garbage collector on embedded sw is a really really bad idea ;)
2012-08-28T20:49:36 < TitanMKD> fragmentation will kill at end
2012-08-28T20:49:47 <+izua_> dynamic allocation is, imo
2012-08-28T20:50:02 <+izua_> but then again, actual computers were less powerful than current mcus at some point :P
2012-08-28T20:50:04 < TitanMKD> yes dynamic allocation shall be forbidden ;)
2012-08-28T20:50:29 <+dekar> well it can only fragment so much, I can live with the restrictions I have
2012-08-28T20:50:34 < TitanMKD> especially for realtime stuff it shall be totally avoided
2012-08-28T20:50:40 <+dekar> but I realized it could be a problem for some use cases

2012-08-28T21:10:34 < jpa-> dekar: good to know
2012-08-28T21:11:04 < jpa-> dekar: i wonder if a different memory allocator could do better job about this
2012-08-28T21:11:22 < jpa-> e.g. preallocating more memory to have it ready for realloc() later (does lua use realloc?)
2012-08-28T21:13:09 < jpa-> i wonder if lua could move around objects in order to defrag memory
2012-08-28T21:15:25 < TitanMKD> Anyone know where is described the official Arduino Pinout ?
2012-08-28T21:40:02 < Erlkoenig> dekar: why do you use Lua on a mikrocontroller?
2012-08-28T21:40:57 < jpa-> Erlkoenig: because it is more high-level than C or C++
2012-08-28T21:41:14 < jpa-> i'm looking to use Lua in my next project also
2012-08-28T21:41:47 < zyp> for a lot of people, being highlevel is a good reason to not use it on a microcontroller
2012-08-28T21:41:51 < zyp> :p
2012-08-28T21:42:09 < Erlkoenig> uhm... it seems to not even have classes?
2012-08-28T21:42:18 < BrainDamage> it has no oop
2012-08-28T21:42:42 < Erlkoenig> so C++ is more highlevel? :D
2012-08-28T21:42:50 < BrainDamage> no
2012-08-28T21:42:50 < jpa-> in a different way
2012-08-28T21:43:06 < BrainDamage> lua is great wrt managing memory
2012-08-28T21:43:11 < BrainDamage> as in, it's very painless
2012-08-28T21:43:21 < jpa-> ask dekar just how painless it is :)
2012-08-28T21:43:27 < Erlkoenig> "wrt"?
2012-08-28T21:43:33 < zyp> with regards to
2012-08-28T21:43:39 < BrainDamage> I mean as user, not as fitting a target :p
2012-08-28T21:43:57 < BrainDamage> you can create and access multi dimensional arrays/matrices with 1 line of code
2012-08-28T21:44:03 < Erlkoenig> you mean, more easy than like C/C++?
2012-08-28T21:44:09 < BrainDamage> much more
2012-08-28T21:44:10 < zyp> BrainDamage, you mean «lua is great because you don't have to manage your memory»
2012-08-28T21:44:24 < BrainDamage> yeah that
2012-08-28T21:44:37 < zyp> do you find memory management in C/C++ hard?
2012-08-28T21:44:44 < BrainDamage> it's very popular with game engines as scripting engines
2012-08-28T21:44:47 < Erlkoenig> ruby and lots of other script languages have an equally easy mem management?
2012-08-28T21:44:52 < BrainDamage> not particularry
2012-08-28T21:45:04 < BrainDamage> but many don't want to bother
2012-08-28T21:45:11 < BrainDamage> so lua is a good choice
2012-08-28T21:45:26 < zyp> when you are counting your memory in kilobytes, you should bother.
2012-08-28T21:45:29 < jpa-> for me, an important point would be to cleanly separate "user modifiable" code from the low-level code
2012-08-28T21:45:42 < BrainDamage> zyp: talking about general pourpose computing
2012-08-28T21:45:48 < BrainDamage> not micro specific
2012-08-28T21:46:11 < zyp> jpa-, nothing stops you from doing that with machine code
2012-08-28T21:46:46 < zyp> even on cortex-m you can have a seperate os from user processes with the MPU and do dynamic linking
2012-08-28T21:47:02 < jpa-> zyp: yep, though getting nice stack traces from native code etc.. a lot of pain
2012-08-28T21:47:50 < Erlkoenig> more pain then dynamic memory management for dynamic scripting languages?
2012-08-28T21:47:58 < jpa-> Erlkoenig: yes
2012-08-28T21:48:10 < zyp> BrainDamage, agreed
2012-08-28T21:48:21 < zyp> that's why I'm doing all my host side stuff in python
2012-08-28T21:48:22 < Erlkoenig> and when using a debugger you get meaningful stack traces ;)
2012-08-28T21:48:52 < jpa-> yeah; works for me, not if i want to allow arbitrary users to easily modify the code
2012-08-28T21:49:16 < zyp> nothing stops you from writing a stack trace routine and invoke it after trapping a bug in a user thread
2012-08-28T21:49:56 < jpa-> and read symbols from elf to print stuff and basically implement an embedded version of gdb to find out symbol values etc?
2012-08-28T21:50:11 < zyp> I've considered writing a gdb server that I can put into my code, and use to debug threads without having a hardware debugger
2012-08-28T21:50:34 < Erlkoenig> you mean like, examining the stack and finding the called functions from the return adresses?

2012-08-28T21:50:51 < jpa-> compared to this 200 lines that prints a nice usable stack trace without needing to hook up a debugger or even to be near a computer when the error occurs https://github.com/PetteriAimonen/QuadPawn/blob/master/Runtime/amx_debug.c
2012-08-28T21:50:58 < jpa-> Erlkoenig: yes, and parameters
2012-08-28T21:51:40 < zyp> jpa-, you are aware of core dumps?
2012-08-28T21:51:46 < Erlkoenig> sounds interesting... and complicated ;)
2012-08-28T21:52:08 < jpa-> zyp: i am, i have used them, they are always a bit of pain
2012-08-28T21:52:35 < jpa-> it's a bit of a case "works for me, but if i can make it just a bit easier, i don't have to do everything myself"
2012-08-28T21:53:38 < Erlkoenig> so i am happy the discovery has debug hardware ;)
2012-08-28T21:56:07 < jpa-> in fact.. i'd probably put a processor strong enough to run full python, if only there were good choices that wouldn't take weeks to learn
2012-08-28T21:56:23 < jpa-> i'm already going with the largest STM32F4 (1MB flash, 192kB ram)

2012-08-28T21:57:29 < Erlkoenig> but don't you loose much of the nice execution speed of such a nice fast controller?
2012-08-28T21:58:21 < jpa-> i will make all the performance-critical parts in C, of course
2012-08-28T21:59:02 < jpa-> the thing is that i want the user interface and high-level stuff to be easily modifiable by other people at the company.. who are not embedded software engineers
2012-08-28T21:59:24 < jpa-> (and i don't want to bundle a rasberry pi inside there :D
2012-08-28T21:59:41 < Erlkoenig> would that be so difficult in "high level C/C++", when having a few nice library functions?
2012-08-28T21:59:59 < BrainDamage> isn't there a "microcontroller" python already?
2012-08-28T22:00:03 < Erlkoenig> at least i think more people know coding in C/C++ than in Lua ;)
2012-08-28T22:00:24 < jpa-> BrainDamage: there is, that's my other alternative
2012-08-28T22:00:27 < jpa-> (pymite)
2012-08-28T22:00:55 < BrainDamage> I was thinking of https://code.google.com/p/python-on-a-chip/
2012-08-28T22:01:00 < jpa-> yeah, that
2012-08-28T22:01:50 < jpa-> it's GPL, though
2012-08-28T22:02:16 < zyp> I've considered trying it
2012-08-28T22:03:06 <+Steffanx> but
2012-08-28T22:03:07 < zyp> but then I would mostly be interested in rapid prototyping in interactive mode, not really doing permanent implementations in python
2012-08-28T22:03:48 < Erlkoenig> uhoh... thats exactly the stuff that will remain forever and be an endless nightmare *g*
2012-08-28T22:04:05 < jpa-> Erlkoenig: actually python is the most popular in our company.. but not having to dig down to a debugger is probably the most important part
2012-08-28T22:04:18 < zyp> Erlkoenig, not in interactive mode
2012-08-28T22:05:06 < Erlkoenig> and i laughed at some programmer-n00b who asked my whether i'd program my mikrocontrollers in Java...
2012-08-28T22:05:32 < zyp> Steffanx, the reason I haven't tried it yet is probably because my usb code aren't fully capable of creating a bidirectional data pipe yet :p
2012-08-28T22:05:44 <+Steffanx> He
2012-08-28T22:06:40 < jpa-> Erlkoenig: TINI has been around for years

2012-08-28T22:07:27 < Erlkoenig> Tini? http://www.tini-ev.de/
2012-08-28T22:07:46 < jpa-> BrainDamage: sure, but i mean *always* having to dig into a debugger
2012-08-28T22:08:03 < BrainDamage> ok ok :p
2012-08-28T22:08:06 < jpa-> e.g. you have one little exception and only way to see any relevant info is to launch a debugger
2012-08-28T22:08:54 < jpa-> as it is with C and usually even with embedded C++, because the best you can get is just a bunch of function addresses you still need to decode anyway
2012-08-28T22:09:17 < Erlkoenig> jpa-: yeah well i laughed because that noob was someone "i can do anything with my java and don't know anything else"
2012-08-28T22:09:29 < jpa-> Erlkoenig: http://www.apms.com.au/tini/
2012-08-28T22:09:40 < BrainDamage> you can link to certain libs that auto resolve stacktraces
2012-08-28T22:09:48 < BrainDamage> but means having debug symbols available
2012-08-28T22:09:56 < BrainDamage> and extra efforts to include in your program
2012-08-28T22:09:59 < jpa-> yeah.. a viable alternative perhaps
2012-08-28T22:10:14 < BrainDamage> they are useful to collect error data from users tough
2012-08-28T22:10:26 < jpa-> Erlkoenig: well, he can do a lot of things with his java
2012-08-28T22:10:46 < jpa-> (heck.. the people at my company program FPGA's using labview and i'm very much disgusted)
2012-08-28T22:11:04 < Erlkoenig> yeah... but not looking at anything else than Java is maybe somewhat ignorant or something
2012-08-28T22:11:06 <+Steffanx> labview ....
2012-08-28T22:11:17 < BrainDamage> how does that even work?
2012-08-28T22:11:27 < BrainDamage> labwview generates some vhdl?
2012-08-28T22:11:36 <+Steffanx> using a 10k$ piece of hw dongle
2012-08-28T22:11:42 < jpa-> yes, it turns out there is a special FPGA mode available for labview
2012-08-28T22:11:44 <+Steffanx> like everything else with labview
2012-08-28T22:11:55 < jpa-> yes, veryy expensive and veryy slow
2012-08-28T22:12:08 < BrainDamage> it's true that anything "labview compatible" get it's price bumped 3x

2012-08-28T22:17:07 < jpa-> nice thing about lua is that the compiler should fit on the microcontroller also; therefore i can simply put the files on a flash memory and they can be directly modified using text editor; let alone the possibilities of an interactive prompt
2012-08-28T22:17:48 < Erlkoenig> like the old BASIC computers? :D
2012-08-28T22:18:52 < jpa-> yes, and like python prompt etc.
2012-08-28T22:18:56 < jpa-> a great learning tool
2012-08-28T22:20:37 < Erlkoenig> i could come across the idea that programming beginners might want to start with the PC that's already standing around their room
2012-08-28T22:21:21 < jpa-> not just for programming noobs, works also for learning whatever special device there is to learn

2012-08-28T22:23:27 < emeb> why not use uBASIC?
2012-08-28T22:23:46 < jpa-> emeb: because basic as a language is not so great

2012-08-28T22:28:07 < Laurenceb_> exactly
2012-08-28T22:28:39 < jpa-> Erlkoenig: i mean to use computer as a terminal
2012-08-28T22:28:41 < Erlkoenig> thats why you use an arduino or someting
2012-08-28T22:28:53 < Erlkoenig> jpa-: then you can use the computer as C/C++ compiler as well :D
2012-08-28T22:28:57 < jpa-> Erlkoenig: true
2012-08-28T22:29:20 < jpa-> not the same level of interactivity as a python/lua prompt, but not too important
2012-08-28T22:30:19 < Erlkoenig> but faster execution because lack of compiler
2012-08-28T22:30:26 < Erlkoenig> argh
2012-08-28T22:30:30 < Erlkoenig> -compiler +interpreter
2012-08-28T22:30:48 < jpa-> doesn't matter where speed is not an issue
2012-08-28T22:32:49 < jpa-> there is really a lot of things that make lua/python/etc. a lot easier to program in than C/C++.. bounds checking, automatic memory management, syntactic sugar, introspection
2012-08-28T22:33:06 < BrainDamage> "high level" languages are basically to be used where programmer time matters more than execution time
2012-08-28T22:33:12 < jpa-> indeed
2012-08-28T22:33:35 < Erlkoenig> i use high level languages too ;) but not on mikrocontrollers, at least until now
2012-08-28T22:33:47 < jpa-> microcontroller is just another computer
2012-08-28T22:33:56 < jpa-> if a high-level language fits on it, why not use it?
2012-08-28T22:34:34 < Erlkoenig> because it hurts my brain :D
2012-08-28T22:34:54 < jpa-> your brain is not very tolerant :)
2012-08-28T22:36:48 < jpa-> i find the gap between embedded software and desktop software surprisingly large
2012-08-28T22:37:08 -!- daku is now known as DaKu
2012-08-28T22:37:26 < jpa-> while the different devices available form a continuum without any real gap
2012-08-28T22:38:37 < jpa-> also for some reason a lot of embedded code is horrible kludge and downright ugly :D
2012-08-28T22:38:39 < Erlkoenig> depens... devices like the A10 are closing the gap
2012-08-28T22:41:43 < jpa-> i said there is no device gap; there is software gap
2012-08-28T22:42:10 < Erlkoenig> yeah - "with OS" and "without OS"
2012-08-28T22:42:15 < jpa-> nope
2012-08-28T22:42:35 < jpa-> freertos, chibios etc. are very small
2012-08-28T22:43:30 < Erlkoenig> but somewhat posix/win32 -notcompliant *g*
2012-08-28T22:43:52 < jpa-> yeah, posix compliance is part of the gap
2012-08-28T22:44:54 < jpa-> also dynamic linking.. though just getting posix compliance and dynamic linking is not going to close the gap, they are just somehow artefacts of not having to care about every byte, and about needing to write complex systems

2012-08-28T22:46:18 < jpa-> openwrt-running boxes are a strange middleground, for they run a full OS yet are too small for most of the desktop software libraries
2012-08-28T22:47:10 < jpa-> Erlkoenig: but if you want to do something complex, should you always need to 1) spend a lot of time or 2) put a real computer instead of microcontroller
2012-08-28T22:48:07 < jpa-> i think it is just a matter of there being a lack of good small libraries, with clearly specified goal and little external dependencies
2012-08-28T22:48:36 < Erlkoenig> aren't there plenty of libraries? for talking with specific hardware, like SD Cards, RFM12 chips etc. ?
2012-08-28T22:49:06 < Erlkoenig> or 3) use a big mikrocontroller with a RTOS
2012-08-28T22:49:06 < jpa-> those are the traditional microcontroller taks
2012-08-28T22:49:09 < jpa-> *tasks

2012-08-28T22:49:51 < Erlkoenig> because they need lots of computing power? :D
2012-08-28T22:49:57 < Erlkoenig> thats not found on, e.g. an ATmega8? :D
2012-08-28T22:50:13 < jpa-> yeah, atmega8 is too small, but stm32 is not
2012-08-28T22:50:26 < Erlkoenig> for an html viewer? humm

2012-08-28T22:58:44 < Erlkoenig> but two mikrocontrollers are more expensive than one :D
2012-08-28T22:58:58 < zyp> depends on the microcontrollers.
2012-08-28T22:59:16 < jpa-> also programmer time is very expensive
2012-08-28T23:00:16 < zyp> Erlkoenig, consider OMAP4
2012-08-28T23:00:17 < jpa-> basic (not "smart") phone manufacturers would surely have a lot of very useful stuff, if it just was packaged as libraries and released to the public
2012-08-28T23:00:34 < zyp> pretty much everyone have heard that OMAP4 is a dual core cortex-A9 SoC
2012-08-28T23:00:52 < zyp> but it also has two M3 cores
2012-08-28T23:02:31 < Erlkoenig> why then are there so many projects on the net with AVR's and no OS at all?
2012-08-28T23:02:47 < jpa-> because those projects are simple
2012-08-28T23:02:50 < Erlkoenig> maybe because it's simpler? and its somewhat fun to be near the hardware?
2012-08-28T23:03:29 < jpa-> sometimes you need to do complex things :)
2012-08-28T23:03:43 < zyp> Erlkoenig, because you don't know about them
2012-08-28T23:03:56 < zyp> to take an example: chibios supports avr
2012-08-28T23:03:58 < jpa-> (and not pay $100 for an arduino wifi shield :)
2012-08-28T23:04:30 < Erlkoenig> maybe people say "i dont want no OS i want to learn it myself" :D
2012-08-28T23:04:59 < BrainDamage> an os is useful for generally few pourposes: hardware abstraction, task management, memory management
2012-08-28T23:05:04 < zyp> Erlkoenig, and then there is the question; what do you consider an OS?
2012-08-28T23:05:27 < BrainDamage> the latter 2 are basically useless for single pourpose hardware / simple tasks
2012-08-28T23:05:32 < Erlkoenig> zyp: certainly not windows. :D
2012-08-28T23:05:48 < BrainDamage> hardware abstraction can be done using libs, or simply by ignoring it or relying on compatible hw
2012-08-28T23:07:26 < zyp> Erlkoenig, would you for instance consider my stm32 support code an OS? it does hardware abstraction and some basic multithreading
2012-08-28T23:07:45 < bgamari> zyp, The OMAP4 has two M3s?
2012-08-28T23:07:50 < zyp> bgamari, yes
2012-08-28T23:07:56 < bgamari> zyp, Are they accessible for user code
2012-08-28T23:08:12  * bgamari assumed the PRUSS filled this space on OMAP
2012-08-28T23:08:16 < Erlkoenig> how do you abstract access to hardware like the timers? they vary greatly among controllers, with very different capabilities... especially when multiple timers on one µC are different
2012-08-28T23:08:41 < bgamari> zyp, TRM reference?
2012-08-28T23:08:44 < zyp> bgamari, iirc the M3s replaced PRUSS on OMAP4
2012-08-28T23:10:01 < zyp> I was kind of disappointed when I got a beaglebone and discovered the PRUSS stuff instead of some M3 cores :p
2012-08-28T23:10:15 < bgamari> excellent
2012-08-28T23:10:45 < zyp> oh, and OMAP5 got M4 cores instead
2012-08-28T23:10:46 < zyp> :p
2012-08-28T23:11:30  * bgamari was once considering using the PRUSS to run an analog feedback loop

2012-08-28T23:51:19 -!- grummund [~user@unaffiliated/grummund] has joined ##stm32
2012-08-28T23:51:31 < Erlkoenig> that explains everything.
2012-08-28T23:52:07 < zyp> i.e. the lowest one is strictly not abstraction, but direct register access
2012-08-28T23:52:26 < zyp> and then I can put a generic pwm layer on top of that
2012-08-28T23:52:27 -!- upgrdman_ [42a6d414@blender/artist/upgrdman] has joined ##stm32
2012-08-28T23:52:57 < Erlkoenig> that works because PWM is a simple thing every timer can do...
2012-08-28T23:53:03 < zyp> exactly
2012-08-28T23:53:17 < Erlkoenig> but you know the stm32f4 timers they can do a crazy lot of stuff
2012-08-28T23:53:46 < zyp> if you only need pwm, you use the generic layer that's portable to any timer
2012-08-28T23:54:04 < Erlkoenig> that, e.g. the AVR's can't do... so you have fun querying what the timer can do and what not
2012-08-28T23:54:17 < zyp> if you need crazy stuff, your code won't be portable to timers not supporting crazy stuff, so there is no point in abstracting that
2012-08-28T23:54:38 < zyp> querying how?
2012-08-28T23:54:38 < BrainDamage> that's why you have hw specific code for the specific problem
2012-08-28T23:54:40 < Erlkoenig> that's what i wanted to say :D if you bug a µC which can do crazy stuff, you probably will ned it :D
2012-08-28T23:55:03 < BrainDamage> you don't *want* to have a generic lib that handles all the cases
2012-08-28T23:55:09 < Erlkoenig> zyp: well the user code queries the library "can my timer decode pwm's?" or something
2012-08-28T23:55:09 < BrainDamage> nobody would ever want to use it
2012-08-28T23:55:17 < Erlkoenig> exactl
2012-08-28T23:55:18 < Erlkoenig> y
2012-08-28T23:55:33 < zyp> Erlkoenig, why would it? what would the user code do if the timer can't decode pwm?
2012-08-28T23:56:13 < Erlkoenig> crashing? :D
2012-08-28T23:56:36 < zyp> the point of abstraction is not to make user applications fully portable between different MCUs, the point is to make modules portable
2012-08-28T23:56:57 < Erlkoenig> and what if a module depends on timers?
2012-08-28T23:57:12 < zyp> if I have a generic pwm abstraction layer, I can make a generic motor control module to interface with ESCs using pwm
2012-08-28T23:57:22 < zyp> and that module will be portable to any mcu
2012-08-28T23:57:45 < Erlkoenig> but what if you need a crazy combination of mulitple timers and dma in you module`
2012-08-28T23:58:09 < zyp> then you write a module that will only work on a specific microcontroller
2012-08-28T23:58:37 < zyp> at that point you make the api of that module another abstraction layer, so you just exchange the whole module on another microcontroller
2012-08-28T23:59:13 < upgrdman_> anyone know of an effective way to remove the pin headers on the discovery boards? for small headers i normally do a solder bridge and pull them out... but that won't work too well with those huge arrays on the disco boards
2012-08-28T23:59:40 < BrainDamage> can you waste 10$?
2012-08-28T23:59:55 < BrainDamage> you can buy a cheap soldering iron with integrated solder sucker
--- Day changed Wed Aug 29 2012
2012-08-29T00:00:11 < BrainDamage> since the pins are plated trough hole, it's the only way
2012-08-29T00:00:11 < Laurenceb_> i pull them out pin by pin with pliers
2012-08-29T00:00:21 < zyp> I was about to suggest what Laurenceb_ said
2012-08-29T00:00:30 < BrainDamage> ok, the painful way :p
2012-08-29T00:01:01 < BrainDamage> I wish they just left the holes open and gave you the pin header stripes :/
2012-08-29T00:02:14 < zyp> time to invent solder pliers
2012-08-29T00:02:31 < zyp> so you can apply heat and pull them out with the same tool in one operation :p
2012-08-29T00:02:49 < upgrdman_> hum, i can get a solder sucker... will that work as well with a regulat iron (hakko 888 if that matters)
2012-08-29T00:03:07 < BrainDamage> the probem is heating and sucking at the same time
2012-08-29T00:03:08 < upgrdman_> i never really liked solder suckers, but i should give them another try. wick isn't cheap :)
2012-08-29T00:03:10 < zyp> forget about that, the holes are plated
2012-08-29T00:03:25 < zyp> upgrdman_, I've never liked wick
2012-08-29T00:03:40 < zyp> I've always had much better experiences with solder suckers
2012-08-29T00:03:45 < upgrdman_> really? ok. i love wick
2012-08-29T00:04:39 < zyp> that's probably because I learned solder suckers when I first started soldering
2012-08-29T00:04:45 < upgrdman_> regarding the stm32f4, in the disco board manual they list pins that can do, for example, "TIM1_CH1" and "TIM_CH1N" ... wtf is "N"?
2012-08-29T00:04:52 < BrainDamage> for smd suckers are useless tough
2012-08-29T00:04:54 < zyp> negative
2012-08-29T00:04:59 < zyp> i.e. inverted
2012-08-29T00:05:05 < zyp> BrainDamage, not at all
2012-08-29T00:05:10 < upgrdman_> zyp: thats the only diff?
2012-08-29T00:05:45 < zyp> upgrdman_, yes, TIM1_CH1N is the inverted variant of TIM1_CH1
2012-08-29T00:05:52 < upgrdman_> ok. thanks!
2012-08-29T00:05:58 < zyp> it's documented in the TIM1 chapter of the reference manual
2012-08-29T00:06:29 < upgrdman_> ya, about that... havn't ready that chapter yet. still playing with the basic timers. :)
2012-08-29T00:06:36 < upgrdman_> read*
2012-08-29T00:07:15 < zyp> it's intended for purposes where you need both
2012-08-29T00:07:38 < zyp> toggling one line on and one line off at the same time
2012-08-29T00:07:45 < Laurenceb_> its not quite as simple aiui
2012-08-29T00:07:52 < Laurenceb_> you can introduce "dead time"
2012-08-29T00:38:51 < Laurenceb_> which is useful for stopping brushless controller blowing up
2012-08-29T00:42:19 < zyp> how, exactly, are you going to use them for brushless controllers?
2012-08-29T00:42:31 < zyp> in a way that makes deadtime matter
2012-08-29T00:43:16 < BrainDamage> if you have an H bridge

2012-08-29T00:44:17 < zyp> yes, you do that in brushless controllers
2012-08-29T00:44:33 < Laurenceb_> thats what i meant
2012-08-29T00:44:44 < Laurenceb_> use the N channel for the other side
2012-08-29T00:44:54 < zyp> Laurenceb_, are you talking three phase brushless or what?
2012-08-29T00:44:58 < Laurenceb_> oh wait
2012-08-29T00:45:01  * Laurenceb_ fails
2012-08-29T00:45:07 < Laurenceb_> i forgot the third phase
2012-08-29T00:45:50 < BrainDamage> meh, bipolar steppers, 1 H bridge per coil
2012-08-29T00:45:51 < zyp> anyway, three phase brushless have no need for deadtime, there is no risk of shoot through
2012-08-29T00:46:07 < BrainDamage> and brushless are 3x H bridge "halves"
2012-08-29T00:46:52 < zyp> there are six steps in the commutation cycle, and for a given pole the cycle goes like this: H H Z L L Z
2012-08-29T00:47:11 < upgrdman_> if using a n-fet and p-fet, couldnt you just run them from the same trace?
2012-08-29T00:47:31 < BrainDamage> with correct tresholds, etc, yes
2012-08-29T00:47:32 < zyp> so there is never any pole going directly from positive to negative
2012-08-29T00:48:25 < zyp> see http://bin.jvnv.net/f/BdzB6.png for a practical example of this
2012-08-29T00:48:27 < BrainDamage> AB' B'C CA' A'B BC' C'A
2012-08-29T00:48:49 < BrainDamage> just remember that you keep the last side of the half bridge stuck and move to the next
2012-08-29T00:50:25 < zyp> I don't understand your notation
2012-08-29T00:52:06 < BrainDamage> call A, B, C the motor poles
2012-08-29T00:52:25 < BrainDamage> letter normal = connected to Vcc, with apex, connected to gnd
2012-08-29T00:52:27 < zyp> yes, that's what I did in my logic analyzer trace
2012-08-29T00:52:34 < zyp> ah
2012-08-29T00:52:52 < zyp> yes, you are right
2012-08-29T00:54:07 < BrainDamage> ofc if you have one side to Vcc to keep current flow you want the other to gnd, so it's very easy to reconstruct the signaling

2012-08-29T05:28:05 < cjbaird> "something very cheap"; vimicro SoC controller. A generic 640x480 security camera.
2012-08-29T05:30:35 < cjbaird> I'm thinking that an improved pixel averaging, which discards outliers (and what're most likely encoding artifacts) will be the next thing to do.
2012-08-29T05:41:47 < cjbaird> imggirl is jpeg-encoding my Science; here's a 32-frame result comparison: http://kildall.apana.org.au/~cjb/out-32simpleaverage.png

2012-08-29T05:59:15 < LeelooMinai> Somehow I have USART2_IRQ firing continuously... I was under the impression that the pending flag will be cleared automatically on entry.  Any tips/ideas?
2012-08-29T06:05:55 < dongs> lyra2: it works as far as I need it to use
2012-08-29T06:06:04 < dongs> lyra2: which is pressing start, and typing first few letters of the program i want to run
2012-08-29T06:08:45 < DLPeterson> LeelooMinai: I don't think the interrupt flags in the status register are cleared automatically.  You should read the SR into a variable, then write to the status regsiter to clear all the various interrupt bits (CTS, LBD, TC, RXNE), and then handle the each of the interrupts that occured.
2012-08-29T06:10:56 < LeelooMinai> I mean global interrupt for USART2
2012-08-29T06:11:19 < LeelooMinai> Shouldn't it go from pending state to active to not pending?
2012-08-29T06:11:52 < DLPeterson> LeelooMinai: yes, I think that should happen automatically
2012-08-29T06:12:09 < DLPeterson> but if you don't clear the bits in the SR, it will get pended again.
2012-08-29T06:13:24 < DLPeterson> *I think*
2012-08-29T06:13:34 < LeelooMinai> Hmm, ok, thx, will focus on those then
2012-08-29T06:15:06 < DLPeterson> LeelooMinai: here is an example of how I do this in a Timer interrupt: https://github.com/hazelnusse/robot.bicycle/blob/master/Interrupts.cpp#L25
2012-08-29T06:19:05 < LeelooMinai> Well, I don't see where... unless you mean inside those CH_IQR...() calls
2012-08-29T06:19:57 < LeelooMinai> A, I see line 27
2012-08-29T06:20:08 < DLPeterson> LeelooMinai: yeah, line 27
2012-08-29T06:21:57 < DLPeterson> LeelooMinai: the CTS, LBD, TC, and RXNE bits in the SR are also all rc_w0, and the rest of the bits in the SR are read only, so you should be able to do:  uint32_t sr = USART2->SR; USART2->SR = ~sr;

2012-08-29T06:23:32 < DLPeterson> LeelooMinai: and then create an if/else or switch block to check which bits in sr were set and handle them appropriately.
2012-08-29T06:27:21 < LeelooMinai> Yes, sure... well, to be honest I more pondering this general idea of interrupts just reoccuring - seems weird to me.
2012-08-29T06:27:29 < dongs> you dont need to clear anything in SR dude.
2012-08-29T06:27:35 < dongs> step1: read it into temp var
2012-08-29T06:27:48 < dongs> if (tempvar & whatever_flag)
2012-08-29T06:27:54 < dongs> then disable txe interrupt if youre done sending
2012-08-29T06:27:59 < dongs> thats all you need to do in global handler
2012-08-29T06:28:18 < dongs> but better off just use DMA

2012-08-29T06:31:16 < LeelooMinai> My original impression was that when a data is moved from the TC register, the TXE even flag is set and then if TXEIE is enabled, an interrupt is generated...
2012-08-29T06:31:56 < LeelooMinai> Now, why would it be generated again afterwards if the data register is not touched?
2012-08-29T06:33:15 < LeelooMinai> I cannot trace this in PDFs

2012-08-29T06:54:46 < DLPeterson> LeelooMinai: I think you mean the DR.  dongs is right about not needing to clear the TXE, TC, or RXNE bits in the SR as that is done when reading/writing the DR. See page 790 of RM0008.
2012-08-29T06:55:54 < LeelooMinai> http://i.imgur.com/b66nT.png
2012-08-29T06:56:37 < LeelooMinai> I know TXE cleared when writing to the this register
2012-08-29T06:57:37 < LeelooMinai> However, my question was more about a scenario where the interupt is generated and inside you don't write to the register. Will it be regenerated?
2012-08-29T06:57:49 < LeelooMinai> I mean interrupt.

2012-08-29T07:06:19 < DLPeterson> LeelooMinai: If you don't clear it manually or by reading/writing DR, then yes, I believe it will be pended again.  But I could be wrong.
2012-08-29T07:07:43 < LeelooMinai> Hmm, I also noticed that TXE and TC flags are set on reset, so I guess when you enable TXE interrupt it will be generated immediately

2012-08-29T07:41:53 < DLPeterson> LeelooMinai: if TXEIE and TCIE are not set in CR1, then the interrupt won't be generated.  So you can keep the global interrupt enabled, and then just set/clear those bits in CR1 when you want interrupts to be generated by the peripheral.
2012-08-29T07:43:38 < DLPeterson> LeelooMinai: on reset, the all the USART interrupt enable bits are clear, so you shouldn't be getting any interrupts until you actually enable them in the peripheral (and in the NVIC)

2012-08-29T09:15:06 < zyp> Laurenceb, because duration of commutation is dictated by motor rpm, you can't commutate faster or slower than the motor spins, otherwise it will stall
2012-08-29T09:17:16 < zyp> pwm controls how much power you supply the motor, which together with load determines how fast it will spin, then you use back-emf sensing to find the rpm and commutation duration
2012-08-29T09:19:58 < zyp> it's kind of like how gasoline engines work; power is controlled by how much air/fuel is injected, which together with load determines rpm, which again determines ignition and valve timing

2012-08-29T15:28:38 <+Steffanx> So bought a cheap pir sensor today.. lets try to do something useful today with it :)
2012-08-29T15:31:19 <+Steffanx> The sensor itself has very advanced datasheet :D
2012-08-29T15:31:23 < jpa-> maybe it can emit some smoke

2012-08-29T15:33:41 <+Steffanx> All PCB should look like this.. you can find all part numbers + resistor values on the pcb

2012-08-29T15:34:31 < jpa-> Steffanx: then there is too much space on the pcb

2012-08-29T15:41:41 < Laurenceb> hmm looks like a thermopile to me

2012-08-29T15:42:47 <+Steffanx> The datasheets says "piezo-electry IR"
2012-08-29T15:43:39 < BrainDamage> thermopile = peltier, thermocouple
2012-08-29T15:43:45 < Laurenceb> oh
2012-08-29T15:43:53 < Laurenceb> its not thermopile then
2012-08-29T15:44:07 < Laurenceb> its one of the thermoelectric sensors
2012-08-29T15:44:17 < dongs> obviously PIR sensor shit
2012-08-29T15:44:34 < BrainDamage> those sensors are PIR = pyroelectric infrared
2012-08-29T15:44:54 < Laurenceb> i think it stands for passive IR
2012-08-29T15:45:01 < Laurenceb> some use thermopiles
2012-08-29T15:45:27 < BrainDamage> mmm, the gradient would be ridicolous, no?

2012-08-29T15:46:43 < Laurenceb> dual element sensor with a FET
2012-08-29T15:46:58 < Laurenceb> bet it would attach to logic level pin
2012-08-29T15:47:23 <+Steffanx> it doesn't
2012-08-29T15:47:31 < Laurenceb> or the wakeup pin on an F1

2012-08-29T17:51:56 < zyp> «Figure 141. Gating timer 2 with OC1REF of timer 1» is that right?
2012-08-29T17:51:59 < Laurenceb> yes
2012-08-29T17:52:10 < Laurenceb> theres a delay
2012-08-29T17:52:13 < zyp> what do you not understand?
2012-08-29T17:52:39 < Laurenceb> timer2-cnt counting is delayed
2012-08-29T17:52:46 < Laurenceb> im not sure by how much
2012-08-29T17:53:26 < Laurenceb> is that a propogation delay or 3 CK_INT clocks?
2012-08-29T17:54:16 < zyp> isn't that just due to uninitialized prescaler?
2012-08-29T17:54:31 < Laurenceb> im seeing the overcall clocked duration for timer2 seems to be 3.5clks shorted than the duration the gate is high
2012-08-29T17:54:36 < Laurenceb> yeah maybe
2012-08-29T17:54:44 < Laurenceb> but that wouldn't explain wehat i see
2012-08-29T17:54:57 < zyp> 3.5 clocks?
2012-08-29T17:55:19 < zyp> doesn't both timers run from the same clock source?
2012-08-29T17:55:27 < Laurenceb> they do
2012-08-29T17:55:32 < Laurenceb> thats why im confused

2012-08-29T17:56:14 < Laurenceb> both timers run at 72mhz
2012-08-29T17:57:25 < zyp> and you have one timer gating the other?
2012-08-29T17:57:30 < Laurenceb> yes
2012-08-29T17:57:35 < Laurenceb> timer3 gates timer2
2012-08-29T17:57:54 < zyp> ok
2012-08-29T17:57:59 < zyp> so, what is wrong?
2012-08-29T17:59:08 < Laurenceb> timer2 seems 3.5 fewer clocks than expected per timer3 period
2012-08-29T17:59:28 < zyp> how do you get .5?
2012-08-29T17:59:37 < Laurenceb> which i cant fix by fudging as it seems to have a half clk
2012-08-29T17:59:43 < Laurenceb> thats whats confusing me
2012-08-29T18:00:24 < Laurenceb> the phase is slowly changing on timer2
2012-08-29T18:00:35 < zyp> how are you arriving at the number 3.5 then?
2012-08-29T18:00:50 < zyp> what are you calculating to get that?
2012-08-29T18:00:50 < Laurenceb> by observing phase over 10 seconds
2012-08-29T18:01:12 < Laurenceb> the number of clks timer2 phase shifts by
2012-08-29T18:01:23 < Laurenceb> divided by timer3 cycles in that time
2012-08-29T18:05:38 < Laurenceb>   TIM_SelectOutputTrigger(TIM3,TIM_TRGOSource_OC2Ref);
2012-08-29T18:05:38 < Laurenceb>   TIM_OC2Init(TIM3, &TIM_OCInitStructure);		//Tim3,ch2 used for gating

2012-08-29T21:53:49 < zyp> Steffanx, I just said it
2012-08-29T21:54:36 < Laurenceb_> hook the sensor up to a pot divider

2012-08-29T21:56:13 < Laurenceb_> so hook it up to porta pin 0 on an f1 and have it wake up
2012-08-29T21:56:58 <+Steffanx> The bare sensor doesn't output anything useful for a uc ( without some fancy amplifier )
2012-08-29T21:57:28 < Laurenceb_> looks like it has a fet in there to me
2012-08-29T21:57:35 < Laurenceb_> so try it in a pot divider

In addition, the MCU family's innovative crossbar technology gives developers the flexibility to assign peripherals to specific pin locations, thereby easing system layout and eliminating pin conflicts.

2012-08-30T18:02:18 < Laurenceb> jpa-: good idea
2012-08-30T18:02:51 -!- DaKu is now known as daku
2012-08-30T18:02:55 < zyp> I've pretty much only got experience with xilinx, and I'm not particularly fond of the toolchain
2012-08-30T18:02:57 < Laurenceb> initialisation order seems to screw things
2012-08-30T18:03:06 < Laurenceb> seriously weird stuff going on here
2012-08-30T18:03:09 < zyp> but I haven't heard much better stuff about the other vendors
2012-08-30T18:03:10 < jpa-> zyp: i usually abstract out the toolchain so that i use ghdl for all simulations and Makefiles for building, and just call the tools to perform synthesis
2012-08-30T18:03:20 < Erlkoenig> zyp: xilinx saved $5 for omitting voltage regulators & fuses on their s3a starter board. learnt it the hard way.
2012-08-30T18:03:33 < BrainDamage> zyp: xilinx or altera is pretty much the same thing nowdays wrt support
2012-08-30T18:03:37 < BrainDamage> as in, both meh
2012-08-30T18:03:53 < zyp> yeah, and everything else is worse? :p
2012-08-30T18:03:53 < BrainDamage> runs in linux ok, by installing a gargantuan ide
2012-08-30T18:03:54 < jpa-> i've used that with altera.. nothing bad about the toolchain as-is, but i'm not fond of the GUI tools
2012-08-30T18:04:12 < zyp> jpa-, I did that myself once
2012-08-30T18:04:22 < BrainDamage> I have quartus 2 installed as well, works ok
2012-08-30T18:04:28 < zyp> but the tools aren't really made to be used by dependency tracking systems like make
2012-08-30T18:04:39 < zyp> so it's kind of pointless
2012-08-30T18:04:53 < jpa-> yeah, make is more of use for running the testbenches
2012-08-30T18:04:58 < karlp> what about lattice?
2012-08-30T18:05:07 < karlp> they seem cheap?
2012-08-30T18:05:12 < BrainDamage> I wish there was an open source compiler, the problem is that it won't happened without gigantic reverse engineering efforts
2012-08-30T18:05:17 < jpa-> siliconblue (now part of lattice) tools looked quite ok, but it's going away now
2012-08-30T18:05:22 < BrainDamage> bitstream format, hardware structure, etc
2012-08-30T18:05:32 < zyp> I was talking to somebody about the lattice stuff with m3 hardcore once, they claimed the toolchain was terrible
2012-08-30T18:07:01 < jpa-> BrainDamage: actually ikarus verilog used to do synthesis, the only propietary part you needed was the place & route backend from the FPGA manufacturer
2012-08-30T18:07:29 < BrainDamage> used to?
2012-08-30T18:08:08 < jpa-> the support was removed, apparently it wasn't that widely used
2012-08-30T18:08:13 < jpa-> now it does only simulation
2012-08-30T18:08:26 < Laurenceb> hmf theres no other way
2012-08-30T18:08:35 < jpa-> Laurenceb: you were born that way?
2012-08-30T18:08:37 < Laurenceb> time to try timer code on maple with big scope connected
2012-08-30T18:09:19 < BrainDamage> http://www.milkymist.org/fpgatools/ this was promising, but never went anywhere
2012-08-30T18:09:53 < BrainDamage> and now the links are dead too :s
2012-08-30T18:10:18 <+izua> all those freetards should start making their own silicon plant
2012-08-30T18:10:37 <+izua> herp derp, let's all design our own video cards and other epic hardware
2012-08-30T18:10:44 <+izua> and maybe, just maybe, open hardware fpgas.
2012-08-30T18:10:49 < Erlkoenig> what would be nice, a thingy that "synthesizes" a more object oriented and concise HDL into VHDL or Verilog, so one can then use the manufacturer's tools to bring it to the hardware
2012-08-30T18:10:57 < jpa-> BrainDamage: still here: https://github.com/errordeveloper/llhdl
2012-08-30T18:11:13 <+izua> i'm not sure how a higher level HDL would look like
2012-08-30T18:11:21 < zyp> Verilog2000
2012-08-30T18:11:26 <+izua> then again, the same thing asm programmers probably thought about python
2012-08-30T18:11:37 < Erlkoenig> not like VHDL, at least *g*
2012-08-30T18:11:39 < jpa-> Erlkoenig: VHDL is quite fine in my opinion :P
2012-08-30T18:11:44 <+izua> ^
2012-08-30T18:11:51 < zyp> VHDL is too verbose
2012-08-30T18:11:55 < Erlkoenig> yep
2012-08-30T18:12:01 <+izua> it's like C
2012-08-30T18:12:13 < Erlkoenig> instantiating entities is way to much typework
2012-08-30T18:12:18 < zyp> no, VHDL compared to Verilog is like Pascal compared to C
2012-08-30T18:12:34 < emeb> this
2012-08-30T18:12:42 < jpa-> Erlkoenig: maybe you would love labview fpga :)  http://foolooo.files.wordpress.com/2010/07/code.png
2012-08-30T18:12:52 < zyp> ugh
2012-08-30T18:12:57 < jpa-> Erlkoenig: what typework, just the port mappings?
2012-08-30T18:13:02 < Erlkoenig> also, there should be a way to define interfaces, so one could easily connect entities with these interfaces together - without connecting each single signal... a bit like "record"s, but bidirectional
2012-08-30T18:13:19 < Erlkoenig> jpa-: everything :D
2012-08-30T18:13:23 < zyp> Erlkoenig, I think Verilog 2000 has that
2012-08-30T18:13:39 < Erlkoenig> graphical design? meh
2012-08-30T18:13:55 < Erlkoenig> hmm perhaps then i should take a look at that verilog
2012-08-30T18:14:00 < zyp> wait
2012-08-30T18:14:02 < zyp> I'm dumb
2012-08-30T18:14:08 < zyp> I'm thinking about SystemVerilog :p
2012-08-30T18:14:26 < BrainDamage> izua: designing might even be possible, the investiment to produce 100k chips not
2012-08-30T18:14:38 < claude_work> labview fpga /me shudders
2012-08-30T18:14:46 < BrainDamage> below 100k, I dubt you'll even get process infos from the silicon fab
2012-08-30T18:14:50 < zyp> Erlkoenig, see http://en.wikipedia.org/wiki/SystemVerilog#Interfaces
2012-08-30T18:15:04 <+izua> that's why they need their own silicon fab
2012-08-30T18:15:10  * emeb just converted a complex function from Verilog to VHDL: result was 2x larger in linecount.
2012-08-30T18:15:19 < jpa-> i wonder if you could pool chip manufacturing like the PCB's are done
2012-08-30T18:15:22 <+izua> linux on a chip would wet a lot of panties
2012-08-30T18:15:24 < Erlkoenig> zyp: ah nice
2012-08-30T18:15:39 < BrainDamage> jpa-: been done since decades
2012-08-30T18:15:43 < emeb> jpa-: google mosys
2012-08-30T18:15:46 < zyp> I had some FPGA stuff in a course at uni
2012-08-30T18:15:47 < jpa-> BrainDamage: still too expensive?
2012-08-30T18:15:50 < BrainDamage> the problem is the crazy mask costs
2012-08-30T18:16:01 <+izua> you can use an older generation tech?
2012-08-30T18:16:09 < zyp> it was taught in VHDL, but I was allowed to use Verilog since I already knew it
2012-08-30T18:16:24 < BrainDamage> izua: still crazy mask costs
2012-08-30T18:16:51 < emeb> correction - mosis. pooled chip mfg.
2012-08-30T18:17:04 < Erlkoenig> also the way functions work in vhdl is unsatisfactory... one should be able to call "functions" in "instances" (which in fact would only connect signals or something), would allow for more readable designs
2012-08-30T18:17:07 < claude_work> if you don't need analog stuff on the chip , take a look at altera's hardcopy silicon
2012-08-30T18:17:46 < BrainDamage> for an fpga you way, say, 10 metal layers, this means easily 300k$ spent in masks, and I'm talking just about etching the glass
2012-08-30T18:18:27 < emeb> 300k is peanuts compared to leading edge mask costs. Typical > $1e6
2012-08-30T18:18:32 <+Steffanx> Everyone should use that new FPGA from [don't remember] .. DualCore A9 + fpga in one
2012-08-30T18:18:43 < zyp> xilinx zynq
2012-08-30T18:18:48 <+izua> neat?
2012-08-30T18:18:52 <+Steffanx> Yeah, zynq it was
2012-08-30T18:18:58 < Erlkoenig> what does it cost :D
2012-08-30T18:19:04 < emeb> unobtainium
2012-08-30T18:19:07 <+izua> does that mean you can synthesize a program into hdl with the click of an icon?
2012-08-30T18:19:10 < zyp> zedboard is $3-400
2012-08-30T18:19:17 < emeb> Xilinx announces long before availability.
2012-08-30T18:19:31 < zyp> zedboard should be available around now, no?
2012-08-30T18:19:36 <+Steffanx> The price for the board is 'ok'-ish for me ..
2012-08-30T18:19:53 < zyp> «Shipping Sep 04»
2012-08-30T18:20:00 < jpa-> http://cmp.imag.fr/products/ic/?p=prices  hmm, less than $2k (350nm 2x2mm)
2012-08-30T18:20:07 < Erlkoenig> $895 , duh
2012-08-30T18:20:20 < emeb> heh - everyone will want one.
2012-08-30T18:20:28 < emeb> R-Pi watch out.
2012-08-30T18:20:33 <+Steffanx> LOL

2012-08-30T18:21:09 <+Steffanx> Academic price ..
2012-08-30T18:21:26 < zyp> yeah, if I'm getting it, I'm asking a friend working at uni to get it for me :p
2012-08-30T18:21:38 < emeb> Apply for a night course at the local community college - get student discount.
2012-08-30T18:21:43 <+Steffanx> :P
2012-08-30T18:21:57 < BrainDamage> emeb: I was talking about super cheap old process
2012-08-30T18:21:58 < zyp> though, while $300 is not that expensive, it's expensive for yet another dust collector
2012-08-30T18:22:13 <+Steffanx> For sure
2012-08-30T18:22:14 < BrainDamage> "affordable"
2012-08-30T18:22:14 < zyp> and I don't really need more of those
2012-08-30T18:22:32 < emeb> BrainDamage: Fine - but you won't get much in the way of resources then.
2012-08-30T18:22:33 < zyp> so I'm putting it off for now
2012-08-30T18:23:07 < BrainDamage> emeb: it's all a theoretical talk this one, I don't think anyone woud be enough insane to invest in it
2012-08-30T18:23:17 < emeb> zyp: tech stuff always gets cheaper with time - don't pay the early adopter tax.
2012-08-30T18:23:27 < emeb> BrainDamage: yep
2012-08-30T18:23:39 < zyp> emeb, doesn't really apply
2012-08-30T18:24:01 < zyp> emeb, https://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,792&Prod=S3EBOARD <- this is still as expensive as it were when I bought one five years ago
2012-08-30T18:24:37 < Tzacks> hey guys, i checked the zedboard on the link you posted, and can you explain why there is "motor control" between target applications? i find this motor control almost everywhere i look, does that require so much processing power or what?
2012-08-30T18:24:43 < emeb> Yeah - but OTOH, you can slap a Xilinx S3A chip down on your own board for < $20.
2012-08-30T18:24:53 < BrainDamage> Tzacks: the opposite
2012-08-30T18:25:06 < Tzacks> how do you mean the opposite?
2012-08-30T18:25:26 < BrainDamage> because it requires almost no resources, everyone can list it in the possible targets
2012-08-30T18:25:29 < zyp> Tzacks, mostly precise timing
2012-08-30T18:25:42 < zyp> also what BrainDamage said
2012-08-30T18:25:47 < Tzacks> BrainDamage thats why i had to ask
2012-08-30T18:25:49 -!- claude_work is now known as claude
2012-08-30T18:26:21 < Tzacks> zyp, you can get enough precision with 8bit micros to control any motor you like, thats why i had to ask
2012-08-30T18:26:24 < Erlkoenig> with all these neat superpowerful platforms (like zedboard) who is gonna write applications that take advantage of the power :D
2012-08-30T18:26:30 < Laurenceb> ok wtf
2012-08-30T18:26:39 < Laurenceb> got test working with scope
2012-08-30T18:26:47 < Laurenceb> two timers is correct
2012-08-30T18:26:54 < Laurenceb> three timers and the third goes wrong
2012-08-30T18:26:56 < Erlkoenig> connecting a scope to a circuit always fixes it :D
2012-08-30T18:27:06 < zyp> :p
2012-08-30T18:27:13 < emeb> Erlkoenig: warehouses full of code slaves in S. Asia. write huge libraries of code that the rest of us slap down without thinking.
2012-08-30T18:27:19 < zyp> except when it breaks a working circuit
2012-08-30T18:27:38 < Laurenceb> https://github.com/Laurenceb/STM32-Logger/blob/master/timer.c#L112
2012-08-30T18:27:58 < Laurenceb> so i slave timer2 off timer3
2012-08-30T18:28:01 < Erlkoenig> emeb: i wonder how these learn coding?
2012-08-30T18:28:07 < zyp> probes add a bit load to a circuit, which can pull down floating signals or mess up high speed signals
2012-08-30T18:28:14 < Erlkoenig> do they have, like, specialized universities for that?
2012-08-30T18:28:18 < Laurenceb> and i get 11.97khz as opposed to 11.905
2012-08-30T18:28:24 < Laurenceb> as expected
2012-08-30T18:28:30 < Laurenceb> then i setup timer4
2012-08-30T18:28:41 < Laurenceb> as i get 11.97khz
2012-08-30T18:28:43 < Laurenceb> wtf
2012-08-30T18:28:56 < Laurenceb> is there only one trigger output or something?
2012-08-30T18:29:36 < Erlkoenig> are people in S. Asia allowed to study such things without being fluent in literature and history and such stuff required in 'western' universities?
2012-08-30T18:29:37 < Laurenceb> timer4 should be 11.83khz
2012-08-30T18:30:35 < Laurenceb> theres more than one trigger output right?
2012-08-30T18:30:46 < Laurenceb> its not shared across the whole micro?
2012-08-30T18:31:25 < emeb> Erlkoenig: when nation's school systems are rated on the number of "Engineers" graduated, truck mechanics start counting as "Engineers"
2012-08-30T18:31:35 < zyp> Erlkoenig, that's probably the trick
2012-08-30T18:31:44 < Laurenceb> someonneeeee
2012-08-30T18:31:48 < Laurenceb> help :9
2012-08-30T18:32:09 < Erlkoenig> emeb: if they are able to write nice vhdl code, so they're engineers ;)
2012-08-30T18:32:25 < Erlkoenig> zyp: luckily, western school systems have no urge to catch up
2012-08-30T18:32:27 < emeb> Erlkoenig: s/nice//

2012-08-30T18:32:58 < zyp> Erlkoenig, I think I got off pretty easy

2012-08-30T18:34:35 < Laurenceb> unless there is a typo in the ref manual
2012-08-30T18:34:58 < BrainDamage> what subject?
2012-08-30T18:35:14 < jpa-> Erlkoenig: i'm sure you could have managed it if you just retried
2012-08-30T18:35:21 < zyp> my uni only demanded that I had to take 15 course points worth of «social studies» (or whatever it translates to in english)
2012-08-30T18:35:31 -!- Huitaryan [~Huitaryan@blk-252-42-151.eastlink.ca] has quit [Ping timeout: 256 seconds]
2012-08-30T18:35:40  * emeb had to take diff. eqs. twice... meh.
2012-08-30T18:35:41 < Erlkoenig> jpa-: i tried tree times
2012-08-30T18:35:43 < zyp> a normal semester is 30 course points
2012-08-30T18:35:52 < Erlkoenig> and failed 3 times
2012-08-30T18:35:54 < zyp> I took an english course worth 10
2012-08-30T18:36:05 < zyp> and then I failed some economics bullshit that I never attended
2012-08-30T18:36:21 < emeb> odd how that happens...
2012-08-30T18:36:30 < Erlkoenig> subject was linear algebra 2 (thats not what you thing. what you normally refer to as "linear algebra" is "linear algebra 1", and the "2" part is very different)
2012-08-30T18:36:33 < zyp> but I took a C++ course outside the plan, worth another 10 points
2012-08-30T18:36:46 -!- Netsplit *.net <-> *.split quits: Ranzbak, Oldboy, Rious
2012-08-30T18:36:54 < zyp> so even though I failed the economics course, I still had enough points to graduate
2012-08-30T18:37:14 < zyp> and they apparently forgot about the last 5 points worth of shit
2012-08-30T18:37:14 < jpa-> Erlkoenig: sounds quite relevant for maths :)
2012-08-30T18:37:38 < Erlkoenig> no, not for numerics, which i wanted to specialize for
2012-08-30T18:37:57 < jpa-> zyp: here we have all kind of requirements, but they are negotiable if necessary :P
2012-08-30T18:37:57 < Erlkoenig> also my collegues, who chose more theoretical subjects, don't need it for anything
2012-08-30T18:37:58 < emeb> this was linear algebra for basket weaving?
2012-08-30T18:38:22 < Erlkoenig> what?!
2012-08-30T18:38:37 < zyp> jpa-, I didn't really care about formally graduating, I had already accepted a job offer at that point :p

2012-08-30T18:39:20 < zyp> IMO grades are mostly bullshit anyway
2012-08-30T18:39:28 < Erlkoenig> zyp: great observation...
2012-08-30T18:39:47 < zyp> and I'm not saying it because I have bad grades :p
2012-08-30T18:39:52 < Erlkoenig> exam grades have nothing to do with your real abilities...
2012-08-30T18:39:57 < zyp> yeah
2012-08-30T18:40:03 < jpa-> zyp: heh, around here a diploma is quite important.. i would have a sure job opportunity even if i quit university now, but i don't want to stay there for ever
2012-08-30T18:40:07  * emeb has applied for several jobs where HR wanted a photocopy of his diploma.
2012-08-30T18:40:17 < zyp> well
2012-08-30T18:40:36 -!- Netsplit over, joins: Ranzbak, Oldboy, Rious
2012-08-30T18:40:49 < jpa-> yes, exam grades are quite much orthogonal to what is required at work.. but still very much useful
2012-08-30T18:40:55 < zyp> I never really cared about grades, I just figured that if I learned what I should, the grades should reflect that automatically
2012-08-30T18:40:59 < Erlkoenig> especially in germany... here people pray to the god of paper, especially if the paper has a title "diploma" or "bachelor"
2012-08-30T18:41:03 < jpa-> programming is better learned as a hobby anyway :)
2012-08-30T18:41:08 < karlp> sometimes
2012-08-30T18:41:19 < zyp> so I've never put much work into reading before exams
2012-08-30T18:41:26 < Erlkoenig> oO
2012-08-30T18:41:49 < Erlkoenig> i found it impossible to just pass this exam (with 50% of the points) WITH a lot of work befor
2012-08-30T18:41:53 < emeb> once you get the degree, the grades that went into it no longer matter.
2012-08-30T18:42:18 < Erlkoenig> i would be happy with the worst grade, if i just passed -.-
2012-08-30T18:42:34 < zyp> I've never understood how people can put a lot of work into courses and still fail
2012-08-30T18:42:47 < jpa-> but at our university, you get a 400 EUR cash award if you graduate with average >= 4.0! :P
2012-08-30T18:42:48 < Erlkoenig> zyp: then you are a genius, or your courses are easy
2012-08-30T18:43:12 < emeb> true - the only course I failed was one I didn't try at.
2012-08-30T18:43:12 < zyp> jpa-, I have an average somewhere between A and B
2012-08-30T18:43:29 < jpa-> same, not much work for that
2012-08-30T18:43:55 < jpa-> but for some courses i tend to get bad grades with no clear explanation.. i understood the stuff, but somehow the examiner just didn't like my answers
2012-08-30T18:44:08 < zyp> ha, I had one examiner like that
2012-08-30T18:44:20 < Erlkoenig> well, here the examiners like nobodys answers :)
2012-08-30T18:44:35 < zyp> I always got B in his courses
2012-08-30T18:44:40 < Erlkoenig> one calculation error -> everything following wrong -> failed the exam
2012-08-30T18:44:57  * emeb had a correct answer on a test that was marked wrong. Pointed it out to the instructor - he agreed it was right but gave no credit because everyone else had been graded that way.
2012-08-30T18:45:00 < jpa-> check and double-check :)
2012-08-30T18:45:03 < zyp> so on the last of his courses I said «fuck it, I'm not getting an A anyway»
2012-08-30T18:45:08 < zyp> resulted in a C :p
2012-08-30T18:45:10 < Erlkoenig> forgot one number in a formula (of course you have to remember all formulas) -> failed
2012-08-30T18:45:53 < zyp> it's kind of sad, I never got an E on anything
2012-08-30T18:46:09 < zyp> I managed to graduate high school with the entire range of 1-6 on exams
2012-08-30T18:46:20 < jpa-> ah, but there is one exam i have failed totally: tried to pass driving test 3 times, never succeeded
2012-08-30T18:46:31 < zyp> the 1 and 2 was the same exam, first and second try

2012-08-30T18:46:41 < jpa-> it was a bit stressfull time of my life otherwise also, so i just let it be and i still have no driving license
2012-08-30T18:46:49 < zyp> Erlkoenig, in uni? EE
2012-08-30T18:46:59 < zyp> with some CS courses
2012-08-30T18:47:39 < Erlkoenig> http://www.smbc-comics.com/index.php?db=comics&id=2717#comic
2012-08-30T18:47:41 < zyp> that made me pretty suited for working with embedded software :p
2012-08-30T18:47:48 < Erlkoenig> this comic describes it well...
2012-08-30T18:47:57 < zyp> :)
2012-08-30T18:49:11 < Erlkoenig> i'm switching to CS now...
2012-08-30T18:50:15 < zyp> the trick to get away cheap is to study stuff you are already interested in :p
2012-08-30T18:50:55 < jpa-> true :)
2012-08-30T18:51:17 < Erlkoenig> i was (and am still) very interested in maths, but didn't know much... i didn't to CS in the first time because i already know quite something about that
2012-08-30T18:51:34 < Erlkoenig> and wanted to learn things that i didnt already know...
2012-08-30T18:51:56 < karlp> re: under 100k getting quotes, we got a quote on getting an asic made for only 10k parts, it was fairly reasonably priced too in my mind.
2012-08-30T18:52:04 < zyp> the problems with math is that mathematicians are weird
2012-08-30T18:52:53 < Erlkoenig> just "weird"? :D
2012-08-30T18:53:43 < Erlkoenig> and they can't explain. in one lecture, the prof was basically just reading out a book, but explained it *worse* than the book's author
2012-08-30T18:53:57 < zyp> math is fine up to a point, and then they start using a bunch of weird syntax and every letter in the alphabet and then some
2012-08-30T18:54:49 < Erlkoenig> one chapter could have been interpreted in at least two entirely different ways, because it was that unclear :S
2012-08-30T18:54:57 < zyp> as a programmer I'm used to descriptive names and typed variables
2012-08-30T18:55:07 < Erlkoenig> typed variables, yes :D
2012-08-30T18:55:10 < Erlkoenig> that would be great :D
2012-08-30T18:55:39 < zyp> they do some of that in math too
2012-08-30T18:55:51 < zyp> like vectors marked with arrows or bold font or whatever
2012-08-30T18:56:35 < Erlkoenig> no, only the physicist's use arrows :D
2012-08-30T18:56:51 < emeb> It's amazing how much math I've learned long after taking the class - not until I need to use it does it stick in my brain.
2012-08-30T18:57:52 < zyp> I had a hard time understanding quaternions, because people suck to explain it

2012-08-30T18:58:30 < Erlkoenig> in topology the prof omitted the explanation of quaternions, and used them as "easy examples" for the weird stuff
2012-08-30T18:58:58 < zyp> quaternions are really easy after I learned them
2012-08-30T18:59:32 < zyp> and I think I can explain them pretty understandable too
2012-08-30T18:59:40 < zyp> why can't any mathematician do that? :p
2012-08-30T18:59:48 < Erlkoenig> i would like to know that :D
2012-08-30T19:00:13 < zyp> know what?
2012-08-30T19:00:17 < Erlkoenig> if you ask a mathematician "what is a car?" he will give you a longer speech about how to time the ignition of the fuel in the motor, but after that, you still don't know what a car is...
2012-08-30T19:00:26 < Erlkoenig> why mathematicans can't explain well ;)
2012-08-30T19:00:34 < zyp> ah, yeah
2012-08-30T19:00:34 < jpa-> our math professor explained quaternions very well :)
2012-08-30T19:00:58 < zyp> I never asked my math professor about quaternions, it weren't in my course

2012-08-30T19:01:05 < zyp> but I had a really great professor
2012-08-30T19:01:15 < emeb> so what do *you* use them for?
2012-08-30T19:01:21 < zyp> he explained diff. algebra pretty well
2012-08-30T19:01:36 < zyp> the quaternions? quadrotor math :p
2012-08-30T19:01:43 < emeb> figures. :)
2012-08-30T19:03:16 < zyp> and they are really easy to explain if you just start out with how complex numbers can be used as 2D rotation groups, and then just extend that into 3D
2012-08-30T19:03:37 < Erlkoenig> at least, i successfully already forgot everything i learnt at uni
2012-08-30T19:03:53  * emeb uses complex numbers daily for DSP in communications.
2012-08-30T19:04:09 < Erlkoenig> complex numbers are trivial :P
2012-08-30T19:04:12 <+Steffanx>  Erlkoenig, i think almost everyone does that
2012-08-30T19:04:44 < Erlkoenig> Steffanx: it hurts a bit to know that... but whatever
2012-08-30T19:05:05 < Laurenceb> ok wtf
2012-08-30T19:05:14 < Laurenceb> can someone try something for me?
2012-08-30T19:05:18 < zyp> the main difference between 2D and 3D is that in 2D there is only one axis to rotate around, in 3D you can rotate around any arbitrary axis, so instead of the one imaginary component of a complex number, you have three components describing the vector for the rotation axis
2012-08-30T19:05:21 < Laurenceb> anyone got an F1 setup?
2012-08-30T19:05:36 <+Steffanx> Everyone here probably has a discovery VL :P
2012-08-30T19:05:43 < zyp> I haven't

2012-08-30T19:05:57 <+Steffanx> Zyp, you are not 'everyone'
2012-08-30T19:06:07 < zyp> I considered buying one when I got the L1 since they had it
2012-08-30T19:06:18 < Laurenceb> im trying to gate timer4 from timer2
2012-08-30T19:06:22 < zyp> but I decided it was pointless, having stlinkv1 and all
2012-08-30T19:06:24 < Laurenceb> getting very odd results
2012-08-30T19:06:37 < Laurenceb> i can get the other timers to behave ok
2012-08-30T19:08:31 < Laurenceb> if i slave timer4 off timer2 using gated mode with oc1ref
2012-08-30T19:08:45 < Laurenceb> period is not as expected

2012-08-30T19:13:09 <+izua> value line. cheapass €10 board with onboard debugger
2012-08-30T19:13:25 <+dekar> well I have the F4 discovery, which also was cheap
2012-08-30T19:13:26 < emeb> but it's STLINK V1
2012-08-30T19:13:29 < emeb> very buggy...
2012-08-30T19:13:48 < karlp> it's not that bad...
2012-08-30T19:13:50 < emeb> The F0 Discovery is a good deal though - inexpensive and STLINK V2
2012-08-30T19:13:52 < karlp> I use it quite a bit.
2012-08-30T19:14:06 < karlp> you just have to make sure to tell the kernel to completely ignore it
2012-08-30T19:14:12 < zyp> emeb, same for L1
2012-08-30T19:14:13 < karlp> other than that, it doesn't have swo.
2012-08-30T19:14:43 < emeb> ah - true.

2012-08-30T19:19:58 < emeb> Looks like complex numbers, but with j & k axes.
2012-08-30T19:20:16 < zyp> yes, that's what I just said
2012-08-30T19:20:25 < Laurenceb> http://www.flickr.com/photos/chaoticeunoia/7894532916/in/set-72157631320299140/
2012-08-30T19:20:43 < zyp> 18:05:18 < zyp> the main difference between 2D and 3D is that in 2D there is only one axis to rotate around, in 3D you can rotate around any arbitrary axis, so instead of the one imaginary component of a complex number, you have three components describing the vector for the rotation axis
2012-08-30T19:22:22 < emeb> ah - didn't get the 4D nature of the system from your description there.
2012-08-30T19:23:11 < emeb> but a1+bi+cj+dk looks like real + imaginary i + (two more dimensions in j and k)
2012-08-30T19:23:16 < zyp> a 2D complex rotation of a radians is cos(a) + i sin(a), right?
2012-08-30T19:23:33 < emeb> sure?
2012-08-30T19:24:06 < zyp> a 3D complex rotation of a around xyz is cos(a) + (i * x + j * y + k * z) * sin(a)
2012-08-30T19:24:55 < zyp> 3D quaternion rotation*
2012-08-30T19:25:11 < emeb> OK, so (amount of rotation) + vector representing axis of rotation = 4D
2012-08-30T19:25:45 < zyp> sort of
2012-08-30T19:25:51 < emeb> and then it's just algebra.
2012-08-30T19:26:32 < zyp> this always results in a unit quaternion, just like the 2D always results in a unit complex number
2012-08-30T19:26:39 < zyp> i.e. abs() = 1
2012-08-30T19:26:45 < emeb> ja
2012-08-30T19:27:02 < emeb> so you don't end up with scaling errors.
2012-08-30T19:27:44 < zyp> the 3D rotation could also be expressed with only three numbers if you use the axis vector length as the rotation amount
2012-08-30T19:28:02 < zyp> just like the 2D rotation could be expressed with only one
2012-08-30T19:28:17 < emeb> so you'd have to normalize the vector to get the rotation amount...
2012-08-30T19:28:22 < zyp> yep
2012-08-30T19:28:40 < emeb> cute.
2012-08-30T19:28:51 < emeb> save RAM at the cost of compute time.
2012-08-30T19:29:20 < zyp> the advantage with the complex/quaternion forms is that you can multiply them together to compound them
2012-08-30T19:29:55 < emeb> right - just like multiplying complex unit vectors sums the rotations
2012-08-30T19:30:08 < zyp> yes, just like rotation matrices
2012-08-30T19:30:47 < emeb> so, if you've got a bunch of 3D heading corrections to make at once, just multiply them to get the actual heading.
2012-08-30T19:30:54 < zyp> this is handy in quadrotor math, when you are integrating gyro data to get attitude state
2012-08-30T19:31:10 < emeb> makes sense.
2012-08-30T19:31:25 < zyp> you have one quaternion containing state, and then you compound gyro data every time you get a sample
2012-08-30T19:32:56 < emeb> starts looking like a phase locked loop.
2012-08-30T19:33:10 < zyp> :)
2012-08-30T19:34:05 < zyp> there is also another neat trick there
2012-08-30T19:34:37 < zyp> gyro data is a rotation vector, i.e. direction is axis and length is amount of rotation
2012-08-30T19:35:09 < zyp> with short iterations, the rotation amount will always be close to 0
2012-08-30T19:35:28 < emeb> small angle approximation?
2012-08-30T19:35:47 < zyp> yes, so sin(a) = 0 and cos(a) = a
2012-08-30T19:36:00 < zyp> so you get {1, x, y, z}
2012-08-30T19:36:04 < emeb> heh.
2012-08-30T19:36:47 < emeb> so, keep your sample rates high boys and girls.
2012-08-30T19:37:06 <+Steffanx> Yes Sir!
2012-08-30T19:37:33 < zyp> the trick is to just normalize the quaternion afterwards to keep it as a unit quaternion ;)
2012-08-30T19:37:39 < emeb> Now I feel like McCoy after learning brain surgery.
2012-08-30T19:37:52 < emeb> It'll all leak out in 10 minutes. :)
2012-08-30T19:37:56 < zyp> :p
2012-08-30T19:38:12 < zyp> but pretty understandable, right?
2012-08-30T19:38:18 < emeb> Yeah.
2012-08-30T19:38:28 < emeb> thanks for the braindump.
2012-08-30T19:38:31 < zyp> nobody told me this, so I had to use a few weeks to wrap my head around it and work it out myself
2012-08-30T19:38:48 < zyp> and then suddenly everything made so much sense
2012-08-30T19:38:51 < emeb> Write a magazine article or something.
2012-08-30T19:39:14 < emeb> There was an article a few months back on an inertial nav system in CCI, but it glossed over the math.
2012-08-30T19:39:38 < zyp> I've almost considered starting a website to write up stuff that I learn in an understandable manner
2012-08-30T19:39:45 < emeb> That would be handy.

2012-08-30T20:57:27 <+izua> nice commit message.
2012-08-30T20:57:59 <+izua> Its high-level interfaces are largely compatible with the AVR libraries written for the Arduino and Wiring development boards.
2012-08-30T20:58:00 <+izua> shit
2012-08-30T20:58:13 < BrainDamage> exactly
2012-08-30T20:58:28 <+izua> WHY WOULD SOMEONE DO SUCH A HORRIBLE THING
2012-08-30T20:59:10 < zyp> to gain an audience to market it to
2012-08-30T20:59:37 < zyp> if the masses are dumb, you need to appeal to dumb people to get the most sales
2012-08-30T21:01:09 <+Steffanx> I still wonder
2012-08-30T21:01:14 < zyp> and the library under the compatibility layer seems rather decent
2012-08-30T21:01:17 <+Steffanx> Why do people dislike Arduino..
2012-08-30T21:01:22 <+Steffanx> because of it's libraries
2012-08-30T21:01:29 <+Steffanx> or the kind of people using them
2012-08-30T21:01:38 < zyp> or both? :)
2012-08-30T21:01:54 < BrainDamage> personally it's 25%-75%
2012-08-30T21:02:04 < BrainDamage> the libraries are rather limited
2012-08-30T21:02:12 < BrainDamage> everything runs blocking
2012-08-30T21:02:21 < zyp> it has a pretty dumb API, which train the people to do stuff in dumb ways
2012-08-30T21:03:05 < BrainDamage> but seeing stuff like "bricks" or "shields" snapped together without any knowledge whatsoever irriatates me considerably
2012-08-30T21:03:06 <+izua> the pcb also has a pretty weird design
2012-08-30T21:03:12 <+izua> ^
2012-08-30T21:03:29 <+izua> what BrainDamage said. it focuses too much on plug-and-play with slow stuff.
2012-08-30T21:03:56 <+izua> instead of actually doing something right, trying to cram code to the last byte and into limited memory
2012-08-30T21:04:21 <+izua> for the longest time, the serial read was blocking.
2012-08-30T21:04:32 < zyp> my first quadrotor controller used a maple with a protoshield
2012-08-30T21:04:41 <+Steffanx>  /kick zyp :P
2012-08-30T21:04:43 <+izua> now, the upgrade consists of using a signed result, and -1 if nothing is returned.
2012-08-30T21:04:57 < BrainDamage> zyp: but you had a good understanding of the underlying hw, no?
2012-08-30T21:05:05 <+izua> not bad i guess, but it could have used a pointer for data, and a return value ><
2012-08-30T21:05:22 < zyp> BrainDamage, not at the time, it was my first encounter with stm32
2012-08-30T21:05:44 <+izua> Steffanx: +1
2012-08-30T21:05:45 < BrainDamage> I mean of whatever hw extension you used
2012-08-30T21:05:57 < jpa-> i love arduino, even though i have never owned one
2012-08-30T21:06:01 < zyp> ah, of course
2012-08-30T21:06:26 <+izua> jpa-: so you only used it in other people's stuff? ><
2012-08-30T21:06:34 < jpa-> izua: i have never used it either
2012-08-30T21:06:49 <+izua> how can you love it then?
2012-08-30T21:06:52 < jpa-> i'm just happy to see so many newbies able to actually get stuff done
2012-08-30T21:06:57 < zyp> BrainDamage, it was mainly pwm outputs and I2C sensors
2012-08-30T21:07:09 <+izua> ah
2012-08-30T21:07:35 <+izua> yeah, from that point of view, it's a hit
2012-08-30T21:07:52 < BrainDamage> I think my main gripe is the dunning krueger effect
2012-08-30T21:07:52 < jpa-> and i think the arduino code is also very clean looking and well documented, compared to other embedded stuff (take, for example, ST's stdperiph..)
2012-08-30T21:08:20 -!- DLPeterson [~hazelnuss@ims1065d.engr.ucdavis.edu] has joined ##stm32
2012-08-30T21:08:20 < zyp> the nice part about the maple and the protoshield were that I could solder the required connectors to the protoshield, then plug it into the maple, and then I had a nice prototype without any loose stuff hanging around only by wires
2012-08-30T21:08:25 < BrainDamage> I am deeply annoyed when I see someone build the nth led cube and think it's so awesome
2012-08-30T21:08:35 < jpa-> it *is* awesome
2012-08-30T21:08:44 < jpa-> just by different standards
2012-08-30T21:09:09 < jpa-> in the same way, i doubt our codes are so impressive on the global scale
2012-08-30T21:09:18 < BrainDamage> they aren't, exactly
2012-08-30T21:09:31 < BrainDamage> I'd never go bragging with my stuff around
2012-08-30T21:09:42 < zyp> :)
2012-08-30T21:10:17 < jpa-> yeah.. so we are destined to feel bad about ourselves whereas others can be happy about what they are able to do :)
2012-08-30T21:11:07 < jpa-> (and heck, i spent the first 4 years with electronics building persistence-of-vision thingies; is that any better because I used pics instead of arduino?)
2012-08-30T21:11:25 <+Steffanx> No
2012-08-30T21:11:49 <+izua> pics are good bro
2012-08-30T21:11:55 < BrainDamage> it's not the subject, it's the bragging, but the common availability and unoriginality makes it worse
2012-08-30T21:12:11 <+izua> the first one i used was a 12c something
2012-08-30T21:12:29 < jpa-> though it was fun http://koti.kapsi.fi/jpa/vilkutin/kuvat/vilkutin6-nodata.jpg
2012-08-30T21:12:33 <+izua> and i had to keep nopping older code so i can get newer one working
2012-08-30T21:13:00 < zyp> I'm so far pretty happy with how my own usb stack is turning out, but I don't go bragging to my coworker who is the developer of the usb stack in freebsd :p
2012-08-30T21:13:05 <+izua> jpa-: nice.. spaceship?
2012-08-30T21:13:06 < jpa-> BrainDamage: i consider bragging a property of person, not so much about what they can do
2012-08-30T21:13:27 < BrainDamage> what does it mean a property of person?
2012-08-30T21:13:36 < jpa-> BrainDamage: so if they didn't have arduino, they would brag about being able to install linux
2012-08-30T21:13:58 < BrainDamage> ah, a personality trait of the person?
2012-08-30T21:14:05 < jpa-> yeah
2012-08-30T21:14:38 < BrainDamage> I guess, but the hw makes it so they are in direct relation with my interests
2012-08-30T21:14:44 < jpa-> hehe :)
2012-08-30T21:14:53 < jpa-> noobs? in my community? aaaargh
2012-08-30T21:16:23 < jpa-> in my view arduino represents everything programming should be like: easy to reuse code, easy to get into, clean code, well-documented, complex things get done
2012-08-30T21:17:00 < zyp> I disagree
2012-08-30T21:17:05 < BrainDamage> I agree it keeps easy things easy, but it doesn't scale up well
2012-08-30T21:17:08 < jpa-> of course it can't do anything; but nothing is a limitless platform, at some point you need to expand your scope of knowledge
2012-08-30T21:17:09 <+Steffanx> - efficiency ( as in relatively slow )
2012-08-30T21:17:20 <+izua> in a way, i agree with that. although i hate arduino, i came in contact with it multiple times, merely with people buying it and giving it to me instead of asking what should they buy
2012-08-30T21:17:29 < zyp> a lot of this code reuse you are talking about are dirty cut&paste jobs
2012-08-30T21:17:42 < zyp> and far from clean
2012-08-30T21:17:56 < jpa-> zyp: the most prominent libraries seem to be quite good
2012-08-30T21:17:58 <+izua> but it's also exactly what an embedded platform, especially designed for entry-level stuff. bad pcb, weird libraries, oversimplification without explaining the context
2012-08-30T21:18:05 < jpa-> of course the newbies always produce crap
2012-08-30T21:18:13 <+izua> embedded platform shouldn't be like*
2012-08-30T21:18:36 < BrainDamage> designed for entry level isn't inherently bad
2012-08-30T21:18:45 < jpa-> izua: yeah, if i were teaching embedded software/hardware engineers, i probably wouldn't pick arduino as the platform
2012-08-30T21:18:45 < BrainDamage> *some* have to fill that role
2012-08-30T21:18:59 < jpa-> but for self-learning, use what works for you
2012-08-30T21:19:10 < jpa-> too steep learning curve is worse than too low
2012-08-30T21:19:10 <+izua> other platforms aren't as easy for self teaching though
2012-08-30T21:19:35 <+izua> but if you have someone teaching you, then a better platform will likely help along
2012-08-30T21:19:49 < BrainDamage> I'd be really curious the average knowledge reached for self learning when picking arduino as starting point, or a more classical choice
2012-08-30T21:19:56 < BrainDamage> and I say that without any bias whatsover
2012-08-30T21:20:00 < BrainDamage> I'd be really curious
2012-08-30T21:20:12 <+izua> i suppose some people will move on from arduinos
2012-08-30T21:20:38 < jpa-> i wouldn't expect much difference
2012-08-30T21:20:40 <+izua> but i don't expect all of them to do it, since a lot of people don't care about real-time stuff
2012-08-30T21:20:47 < zyp> jpa-, «the best libraries are quite good», isn't that what you are saying?
2012-08-30T21:20:52 < jpa-> considering i started programming in quick basic
2012-08-30T21:20:57 <+izua> hehe
2012-08-30T21:21:01 < jpa-> zyp: no, "the most common libraries"
2012-08-30T21:21:15 < jpa-> zyp: unlike, for example, stm32 where the most common libraries are total crap
2012-08-30T21:21:21 < BrainDamage> I started using visual basic
2012-08-30T21:21:26 < BrainDamage> vb4
2012-08-30T21:21:27 < zyp> yes, and it's reasonable to say that they got common because they are good?
2012-08-30T21:21:29 <+izua> really?
2012-08-30T21:21:55 < BrainDamage> I didn't even know that arrays existed, I used gui elements to store vectors
2012-08-30T21:22:05 < BrainDamage> iterating a list could be seen visually
2012-08-30T21:22:06 <+izua> dat awesome multiwindow tool panels
2012-08-30T21:22:11 < jpa-> newlib is waaaay too bloated for microcontrollers, stdperiph sucks totally
2012-08-30T21:22:16 <+izua> dat awesome windows 3.0 feel
2012-08-30T21:22:24 <+izua> BrainDamage: i recall the ImageList object
2012-08-30T21:22:41 < BrainDamage> and I really mean visually, it was so slow that 1k elements would take 1-2 mins
2012-08-30T21:22:42 <+izua> where you'd dump in a bunch of icons and it could animate them, or distribute them to a dropdown list
2012-08-30T21:22:47 < zyp> libopencm3 seem pretty good
2012-08-30T21:22:51 < BrainDamage> izua: yes!
2012-08-30T21:22:55 < jpa-> zyp: and not very common, yet
2012-08-30T21:22:59 <+izua> zyp: it is. i like it.
2012-08-30T21:23:05 <+izua> way better than stdperiph
2012-08-30T21:23:16 < zyp> I haven't used it, I've only read a good amount of it
2012-08-30T21:23:29 < jpa-> the situation is getting better, but i would expect that a lot of people will stick with stdperiph (or the propietary libraries that come with some compilers)
2012-08-30T21:23:32 <+izua> its examples are also pretty neat.
2012-08-30T21:23:47 <+izua> the only time i spent debugging was figuring out why my usb wasn't enumerating right on multiple machines
2012-08-30T21:23:53 < zyp> libmaple also seems rather good
2012-08-30T21:23:55 <+izua> after i changed the cable, it worked first attempt
2012-08-30T21:23:58 <+izua> zyp: fuck you
2012-08-30T21:23:58 < zyp> and chibios
2012-08-30T21:24:09 <+izua> DIGITAL_WRITE(OFF)
2012-08-30T21:24:22 <+izua> just joking though
2012-08-30T21:24:25 < zyp> izua, I'm talking about libmaple, not the wirish layer on top of it?
2012-08-30T21:24:28 < zyp> -?
2012-08-30T21:24:41 < zyp> they are seperate components
2012-08-30T21:24:49 <+izua> that sounds sane
2012-08-30T21:24:53 < BrainDamage> personally I wouldn't mind if libmaple would make stm32 more popular, altough I'd really love if I could magically censor the noobs from my sight
2012-08-30T21:25:00 <+izua> it's the first time i heard of it
2012-08-30T21:25:10 < BrainDamage> as in, feel free to do what you want, not on my face
2012-08-30T21:25:25 <+izua> oh look
2012-08-30T21:25:28 <+izua> it has an ide too
2012-08-30T21:25:30 < BrainDamage> altough I guess I am hurting myself by checking sites that also publish "maker" related stuff
2012-08-30T21:25:33 <+izua> that looks like arduino ide, but it's green
2012-08-30T21:25:34 <+izua> lol
2012-08-30T21:25:39 <+izua> http://leaflabs.com/docs/ide.html#ide
2012-08-30T21:25:43 < zyp> oh, and if I had enough time and motivation to get something done with my own stuff, it would also be pretty good :p
2012-08-30T21:25:45 < BrainDamage> that's intentional
2012-08-30T21:25:57 < BrainDamage> their idea is actually rather decent
2012-08-30T21:26:03 < BrainDamage> an arduino, on much better hw
2012-08-30T21:26:09 < BrainDamage> magnitudes better for cost
2012-08-30T21:26:18 <+izua> with a VL board, definitely
2012-08-30T21:26:33 < BrainDamage> even with blocking calls, etc, you can still get many more things done
2012-08-30T21:26:50 < BrainDamage> arduino themselves are moving to arm
2012-08-30T21:26:57 < BrainDamage> with atmel's
2012-08-30T21:27:14 < jpa-> huh?
2012-08-30T21:27:17 <+izua> jpa-: dude
2012-08-30T21:27:23 <+izua> you made a freaking lot of those pov toys
2012-08-30T21:27:45 < jpa-> izua: yeah, spent years at it
2012-08-30T21:27:47 <+izua> i love blinking leds myself, but i think you outledded me
2012-08-30T21:27:54 < zyp> BrainDamage, yeah, sam3u
2012-08-30T21:28:09 < BrainDamage> izua: to each his fetish
2012-08-30T21:28:56 <+izua> BrainDamage: you don't like blinking leds?
2012-08-30T21:29:11 < zyp> http://bin.jvnv.net/f/Hnkw7.JPG <- I have a bunch of these, but I never did anything cool with them
2012-08-30T21:29:32 <+izua> awesome
2012-08-30T21:29:39 < BrainDamage> no, I actually hate leds, even on consumer devices I tend to tape them, the only things I like leds for are high power leds for flashlights
2012-08-30T21:30:06 < BrainDamage> or anyway, static illumination in general
2012-08-30T21:30:12 < zyp> I considered writing code to run pwm to those and stream video
2012-08-30T21:30:32 <+izua> i think that's also been done, on an 8x8 RGB matrix
2012-08-30T21:30:57 <+izua> BrainDamage: leds are awesome dude
2012-08-30T21:30:58 < jpa-> i had http://koti.kapsi.fi/jpa/stuff/pix/ledeja.jpg  but never bothered to make a driver board
2012-08-30T21:31:06 <+izua> you can debug all sorts of stuff with them

2012-08-30T22:47:50 < zyp> heh
2012-08-30T22:48:13 < zyp> I hooked up the led matrix to 5V and ran 3.3V signals to it
2012-08-30T22:48:21 < zyp> that didn't work very good.
2012-08-30T22:48:36 < zyp> it runs happily on 3.3V though
2012-08-30T22:48:38 < emeb> safer than the other way.
2012-08-30T22:51:04 < zyp> it's rated for both, led driver does current limiting
2012-08-30T22:53:15 -!- DLPeterson [~hazelnuss@ims1065d.engr.ucdavis.edu] has quit [Quit: leaving]
2012-08-30T22:54:12 < emeb> but driving 5V into signal inputs w/ 3.3V VDD would reverse-bias the ESD diodes & cause trouble inside the chips.
2012-08-30T22:54:53 < emeb> unless there's current-limiting resistors on the signal inputs.

2012-08-30T23:02:42 < Laurenceb_> huh
2012-08-30T23:02:52 < Laurenceb_> spi multiplexer on the back?
2012-08-30T23:03:29 < zyp> shift register, yea
2012-08-30T23:04:06 <+izua> the matrix is much smaller than i imagined
2012-08-30T23:04:09 < emeb> zyp: THAT CODE IS TOO SIMPLE! UR DOIN' IT RONG!
2012-08-30T23:04:23 < Laurenceb_> waveshare is nice
2012-08-30T23:04:26 < zyp> izua, 32mm square
2012-08-30T23:04:38 < zyp> each led is 2x2mm
2012-08-30T23:04:54 < emeb> spi data to the array?
2012-08-30T23:05:14 < zyp> I'm using spi to shift out each row
2012-08-30T23:05:47 < emeb> there's a row counter on the board?
2012-08-30T23:05:53 < zyp> and I could use a timer and output compare to trigger the update of each row
2012-08-30T23:06:08 < zyp> sort of, that's also shift registers
2012-08-30T23:06:24 < emeb> ah - so you load  a '1' and shift it through...
2012-08-30T23:06:33 < zyp> except it's a 0
2012-08-30T23:06:36 < zyp> http://bin.jvnv.net/f/P2IWh.png
2012-08-30T23:07:02 < emeb> yep
2012-08-30T23:07:22 < emeb> your board, or bought elsewhere?
2012-08-30T23:07:33 <+Steffanx> it says zyp@ something :P
2012-08-30T23:07:36 < zyp> :p
2012-08-30T23:07:58 < emeb> heh - not paying attention.
2012-08-30T23:08:01 < zyp> it's some years old, it's the first I ever had fabbed
2012-08-30T23:08:20 < Laurenceb_> why fets at one side?
2012-08-30T23:08:24 < zyp> got a bunch of them, been using them for reflow testing
2012-08-30T23:08:52 < zyp> Laurenceb_, show me a shift register that does 200 mA high side switching
2012-08-30T23:08:57 < zyp> I couldn't find any
2012-08-30T23:09:15 < emeb> Hmm - thought that I found some a while back. Expensive though..
2012-08-30T23:09:38 < Laurenceb_> but isnt the maxim thingy doing it?
2012-08-30T23:09:54 < zyp> no, it's low side switching
2012-08-30T23:10:13 < emeb> TI makes some driver chips that have serial in, PWM control, etc. Not cheap.
2012-08-30T23:10:17 < Laurenceb_> oh i see
2012-08-30T23:10:19 < zyp> and current limiting, so you can't control a variable amount of leds, it would screw up brightness :p
2012-08-30T23:13:01 <+izua> those matrices seem quite the catch
2012-08-30T23:13:10 <+izua> 16x16 matrices run over €50 on ebay
2012-08-30T23:13:33 <+izua> and they seem made out of 4 8x8 boards, not the real thing
2012-08-30T23:13:47 < zyp> I think I got ten for $10
2012-08-30T23:14:22 < zyp> (actually ten for 1000 yen, but that was pretty much equal to $10 at the time)
2012-08-30T23:37:12 < BrainDamage> I really like the saleae probes
2012-08-30T23:37:34 < BrainDamage> the stupid probes I have have the cable run exactly where you're supposed to grip
2012-08-30T23:37:41 < BrainDamage> and it's soldered in, you cannot disconnect
2012-08-30T23:53:19 < zyp> I've considered soldering my saleae probes, because they keep falling off the leads
2012-08-30T23:55:05 < BrainDamage> http://sigrok.org/wiki/Probe_comparison
2012-08-30T23:55:11 < BrainDamage> my case is cheap probe #2
2012-08-30T23:55:42 < BrainDamage> cheap probe #1 doesn't seem too bad
2012-08-30T23:55:53 < zyp> it looks horrible
2012-08-30T23:56:36 < BrainDamage> I care about it actually working and not getting in the way
2012-08-30T23:57:28 < zyp> I mean horrible as it looks like it's single ended and single ended probes are horrible to work with
2012-08-30T23:58:03 < BrainDamage> oh, I don't know if it's single ended
--- Day changed Fri Aug 31 2012
2012-08-31T00:04:14 < zyp> it is very obviously single ended

2012-08-31T00:43:34 < zyp> then don't get them
2012-08-31T00:45:00 < Laurenceb_> they are on the bus pirate
2012-08-31T00:45:20 < Laurenceb_> i poured epoxy down them to get them to grip more
2012-08-31T00:45:38 < Laurenceb_> - put WD48 on the metal first

2012-08-31T00:46:34 < zyp> they are dongs-approved, so they should be pretty good
2012-08-31T00:49:53 < emeb> *cough* (price)

2012-08-31T03:39:17 < dongs> you put the cap on and run it in that mode and it finds shit that looks broken and w ill then replace with nearest pixel or so
2012-08-31T03:40:06 < cjbaird> That's what I did. But I get to experience the joy of doing it from scratch.

2012-08-31T03:40:41 < dongs> whas the final goal
2012-08-31T03:40:44 < cjbaird> Because of the hardware, there's also analogue issues to take into account as well.
2012-08-31T03:40:53 < dongs> integrate it into your leelong laptop?

2012-08-31T03:48:45 < cjbaird> Something the Ham Radio guise keep from people (..because they want you to join their creepy little clubs..) is that the Class Licences controlling most ham radio bands only need a licence if you're transmitting above a certain power. QRP'ing lets you hack in the same bands in any way you want (digital mode, etc. on VOX-only). 1.8MHz Radio links that can be made for a buck, and such.
2012-08-31T03:49:33 < cjbaird> Of course, you need full-call licence knowledge to get into that shit...
2012-08-31T03:50:58 < cjbaird> The sort of power output that can be used is in the order of milliwatts for links ~few kilometres, or ~5 watts to go around the globe.

2012-08-31T05:11:59 < dongs> its not exactly intended to be used as a scope, the point is logic analyzer + siggen

2012-08-31T11:32:12 < dongs> ya
2012-08-31T11:32:29 < dongs> i see the sample collects shit for 5 frames then sends it out
2012-08-31T11:32:49 < dongs> SOF happens constantly?
2012-08-31T11:33:21 < zyp> it's a overhead/latency tradeoff
2012-08-31T11:33:39 < zyp> smaller transfers add more overhead, larger transfers add more latency
2012-08-31T11:33:50 < dongs> right
2012-08-31T11:33:54 < dongs> this doesnt matter though
2012-08-31T11:34:10 < dongs> its one of the modes,,, if its in usb>uart mode, it relays GPS uart over it
2012-08-31T11:34:12 < dongs> for testing/config
2012-08-31T11:34:25 < dongs> so doesnt really matter latency etc.
2012-08-31T11:35:42 < zyp> keep a buffer of incoming bytes, for lowest latency, write what you have in the buffer whenever there is bytes in the buffer and usb is idle
2012-08-31T11:36:14 < dongs> so, is SOF shit calls back every 125us? always? whether thers traffic or not?

2012-08-31T16:04:11 < zyp> dunno
2012-08-31T16:04:13 < dongs> cause tom66 used that

2012-08-31T16:06:56 <+izua> there was a decent one over lucid dreaming "devices"

2012-08-31T16:07:03 <+izua> ie, delayed led blinkers on sleeping masks.
2012-08-31T16:07:12 < dongs> dunno, i dont do drugs
2012-08-31T16:07:25 <+Steffanx> drugs != device
2012-08-31T16:07:25 < dongs> so thats of little value to me
2012-08-31T16:08:18 < dongs> hmm... i gotta figure out a way to unlame this s hit
2012-08-31T16:08:57 < cjbaird> I had a lucid dream once were I was a skunk. As in the critter. I pondered if I should eat bugs..
2012-08-31T16:09:42 <+izua> did you?
2012-08-31T16:10:00 < zyp> cjbaird, that's your mind telling you that you stink and should start showering
2012-08-31T16:11:23 < cjbaird> Which was weird. Lucid dreams usually go "oh wow, I'm in a dream fantasy world. SEXUAL EXCESS AHOY!" ..but I was trotting around on four tiny legs being furry. What a waste.
2012-08-31T16:12:06 <+Steffanx> I guess you're not good enough cjbaird
2012-08-31T16:12:25 <+Steffanx> A pro can turn himself into a 'human' and do fancy stuff

2012-08-31T16:14:06 < cjbaird> Maybe a semi-lucid dream from one time: I convinced a Pizza restaurant to make me a super-sausage-roll by cooking a sausage inside some pizza dough..

2012-08-31T16:15:40 <+izua> the tesla museum?
2012-08-31T16:15:45 < zyp> Steffanx, it's not my fault you're not able to do cool stuff when you are awake, and can only resort to dreaming about it :p
2012-08-31T16:15:59 <+izua> you can make a project like "let's bribe our way into the government to legalize weed everywhere"
2012-08-31T16:16:08 <+Steffanx> Sure zyp
2012-08-31T16:16:10 <+Steffanx> You can fly?
2012-08-31T16:16:19 <+Steffanx> Have 6 arms?
2012-08-31T16:16:29 < dongs> zyp can fly a dongcopter
2012-08-31T16:17:37 < zyp> Steffanx, yea, I can build multirotors with six arms capable of flying
2012-08-31T16:17:51 <+Steffanx> I didn't talk about what you can build
2012-08-31T16:18:12 < zyp> it's still cooler than fantasies

2012-08-31T18:30:36 < Tzacks> i'll try him when hes here then thx
2012-08-31T18:32:21 < Laurenceb> f4discovery looks useful for that
2012-08-31T18:32:29 < Laurenceb> are there any audio demos for it?
2012-08-31T18:33:16 < Tzacks> yup :)
2012-08-31T18:34:06 < Tzacks> i got the same board and want to try some dsp i just need a little advice as i am new to it
2012-08-31T18:37:43 <+izua> emeb recommended me zolzer udo's stuff. the guy has two books, digital audio effects and digital audio signal processing
2012-08-31T18:42:42 < Laurenceb> awsome theres a new bong article
2012-08-31T18:46:24 < Tzacks> izua, i got some good books on that i just wanted to ask if you do some signal filtering and you want to use more then just one filter how it is done, just calculating first one, and then feeding the output to the other one or if it is done some other way
2012-08-31T18:46:33 < Tzacks> i couldnt find example like that anywhere
2012-08-31T18:47:50 < dongs> i'd imagine so
2012-08-31T18:47:59 < dongs> its just sample buffers going around, no?
2012-08-31T18:48:12 <+izua> i'd probably have multiple buffers and having the output of one filter being fed to the other filter
2012-08-31T18:48:41 < Tzacks> yup, thats what i wanted to ask, it shold be easy enough then
2012-08-31T18:49:17 < Tzacks> it will probably take some time until i get into it anyway :)
2012-08-31T18:49:34 <+izua> the thing is that, since it takes one sample for the first filter to output stuff and two samples for the second one (since it needs data from the first one), you'll be adding extra delay with each extra filter
2012-08-31T18:49:53 <+izua> probably not  important with small stuff.
2012-08-31T18:49:57 -!- claude_work is now known as claude
2012-08-31T18:50:00 < Tzacks> yep, i know the principles of it, i just neve done anythink like that before
2012-08-31T18:50:19 <+izua> you should honestly look up VST and get a vst host, like tobybear
2012-08-31T18:50:23 <+izua> and then write a plugin
2012-08-31T18:51:48 < Tzacks> i never heard about tobybear :)
2012-08-31T18:52:08 <+izua> doing this on an embedded device should not produce different results, but it will likely be more time consuming
2012-08-31T18:52:16 <+izua> it's some random dude who wrote a minimal vst client.
2012-08-31T18:52:35 < BrainDamage> linux or windows?
2012-08-31T18:53:06 < Tzacks> most likely stm32 :)
2012-08-31T18:53:09 <+izua> you can get like cubase or fruityloops i guess, but that's way overkill
2012-08-31T18:53:33 < Tzacks> aah i know what you mean now izua
2012-08-31T18:53:38 <+izua> vst effects are implemented as a dll. i think there were some patches for ardour to work with vst
2012-08-31T18:55:56  * emeb is here - Tzacks: what's up?
2012-08-31T18:56:15 < Tzacks> just wanted to ask about audio filtering, how it is done
2012-08-31T18:56:19 < BrainDamage> vst support in ardour is still meh
2012-08-31T18:56:28 < Tzacks> when you want to chain filters
2012-08-31T18:56:30 < BrainDamage> and needs for ardour to be built in 32 bit mode
2012-08-31T18:56:42 < emeb> Tzacks: Well, see - there are numbers...
2012-08-31T18:57:20 < emeb> What sort of filters?
2012-08-31T18:57:27 < emeb> IIR, FIR, etc?
2012-08-31T18:57:36 < Tzacks> yes
2012-08-31T18:57:47 < Tzacks> but the idea only
2012-08-31T18:57:50 < Tzacks> lets say
2012-08-31T18:58:35 < Tzacks> when you want to do two filters lets say high pass and then low pass, you calculate the first one and then you buffer the output walues and you feed them into the other one?
2012-08-31T18:58:45 < emeb> Pretty much.
2012-08-31T18:58:58 < Tzacks> ook that sounds quite  ok
2012-08-31T18:59:10 < emeb> Generally you'll find that there are libraries of filter functions - ST has some DSP stuff ferinstance.
2012-08-31T18:59:25 < Tzacks> im thinking what kind of project to work on in the next school year and i need something a bit advanced, so this is probably it
2012-08-31T18:59:33 < emeb> They usually are block-oriented - you give them a buffer full of sampled data and they crunch it.
2012-08-31T18:59:58 < Tzacks> i know if i want to do it for myself i find libraies online and i use them, but i wont be allowed in the school :)
2012-08-31T19:00:16 < emeb> They make you write from scratch?
2012-08-31T19:00:29 < Tzacks> it depends on complexity and time
2012-08-31T19:00:47 < emeb> No biggie - filters are generally easy to do and you can find examples to learn from.
2012-08-31T19:01:20 < Tzacks> they wouldnt mind if i use a library for fft or so but simple filter must be done from scratch as we study dsp at the course i do
2012-08-31T19:02:09 < Tzacks> i am thinking about wavetable synthesis and some soft synth or so :)
2012-08-31T19:02:20 < Tzacks> hope stm32f4 can do it fast enough
2012-08-31T19:02:25 < emeb> No problem.
2012-08-31T19:02:37 < emeb> I've got wavetable synths running on an F100.
2012-08-31T19:02:58 < emeb> F4 eats that sort of thing for breakfast.
2012-08-31T19:03:16 < Tzacks> can you give some specs what you done?
2012-08-31T19:03:30 < Tzacks> i meen number of oscillator channels filters etc?
2012-08-31T19:04:36 < emeb> On an F100 @ 24MHz I've got 2 morphing/interpolated wavetable oscillators in parallel: http://www.analoguehaven.com/synthesistechnology/e355/
2012-08-31T19:05:23 < emeb> On an F105 @ 72MHz I've got prototype code for a 4chl morphing/interpolated wavetable.
2012-08-31T19:06:24 < Tzacks> that looks quite good
2012-08-31T19:06:29 < emeb> A buddy has a Discovery F4 running 32 additive partials (Sine osc + Env Gen + LFO).
2012-08-31T19:06:51 < Tzacks> yup i would do something like that
2012-08-31T19:07:10 <+Steffanx> [offtopic] That website if awful emeb
2012-08-31T19:07:17 < Tzacks> :))))
2012-08-31T19:07:31 <+Steffanx> RIGHT aligned text :S
2012-08-31T19:07:32 < emeb> And I've got an F405 hooked to a 48kHz 16-bit stereo codec - uses about 3% of the CPU bandwidth to do a simple regenerative delay.
2012-08-31T19:07:45 <+Steffanx> No capitals
2012-08-31T19:07:47 < emeb> Steffanx: Not mine - it's the distributor.
2012-08-31T19:08:12 < Tzacks> aa very good, thnx for info
2012-08-31T19:08:37 < Tzacks> just to finish my stm32 invaders i can't already beat and then i can start wit the dsp finaly :)
2012-08-31T19:11:33 < emeb> np - good luck.

2012-08-31T22:52:02 < cjbaird> 32kB would make faux-shift-registering the video doable. I'm thinking for a bitmap display. Certainly a lot better could be done with text-cell.
