2014-03-01T04:36:55 < Jack3k3> if an interrupt is trigered, i.e. the spi2_irqhandler, does the flag that caused it (i.e. SPI_I2S_IT_RXNE) automatically clear itself
2014-03-01T04:36:59 < Jack3k3> or do I need to clear the flag manually
2014-03-01T04:37:10 < GargantuaSauce> depends on the flag
2014-03-01T04:37:44 < GargantuaSauce> some are cleared by the relevant read/writes to other registers, some are cleared by explicitly clearing the flag
2014-03-01T04:38:27 < GargantuaSauce> i believe that one is cleared by reading the DR
2014-03-01T04:40:57 < gxti> Jack3k3: it's never cleared by doing nothing
2014-03-01T04:41:23 < gxti> but yes, reading DR will clear the RXNE flag
2014-03-01T04:42:42 < Jack3k3> well im actually using i2s
2014-03-01T04:42:57 < Jack3k3> but i was getting the data by reading SPI_I2S_ReceiveData(SPI3)

2014-03-01T04:46:26 < Jack3k3> could someone take a quick look at this, http://codepad.org/6KAxsRF0
2014-03-01T04:47:08 < Jack3k3> thats kinda what im doing, i2s2/spi2 is TX, i2s3/spi3 is RX, trying to trigger when RXNE is set (there is data in the buffer), and TX it via i2s2/spi2

2014-03-01T05:07:41 < qyx_> hm, anyone used lin?
2014-03-01T05:09:06 < qyx_> is there some advantage in using dedicated LIN physical driver ic instead of simple tx transistor when i intend to use LIN at 3.3/5V?
2014-03-01T05:09:28 < qyx_> or better, is there any advantage in using LIN
2014-03-01T05:09:55 < qyx_> there is half duplex uart which basically suits my needs
2014-03-01T05:25:24 < Jack3k3> goood damn it
2014-03-01T05:25:36 < Jack3k3> why does keil lack any stm32 targets
2014-03-01T05:25:40 < Jack3k3> somethings broken
2014-03-01T05:28:12 < Jack3k3> oh i guess its just a software pack? i thought keil used to come with all the standard devices,. weird
2014-03-01T05:29:01 < zippe1> qyx_: I've just been building a bunch of LIN stuff
2014-03-01T05:29:20 < zippe1> Mostly nice to have the xcvr in automotive applications
2014-03-01T05:29:36 < zippe1> if you just want to do single-wire, then you don't need a transistor at all
2014-03-01T05:29:54 < zippe1> Assuming short runs, just configure for single-wire mode and away you go
2014-03-01T05:32:39 < qyx_> it will be around ~2m, multiple slaves, up to 5
2014-03-01T05:32:48 < qyx_> but much smps stuff nearby
2014-03-01T05:33:37 < qyx_> i could do fsk over power lines if i was crazy enough

2014-03-01T08:08:04 < Jack3k3> ok this is driving me crazy
2014-03-01T08:08:15 < Jack3k3> can anyone tell me what they think of this http://imgur.com/U4uWLhU
2014-03-01T08:08:54 < Jack3k3> I'm setting the peripheral in master mode, so it sounds like I dont need to apply SYSCLK, and the uda1380 periph will output SDO/WS/CK
2014-03-01T08:09:18 < Jack3k3> so then do I need to do anything special for setting up the receiving I2S on the stm32?
2014-03-01T08:18:09 < emeb_mac> so the codec is master and the STM32 I2S port must be a slave
2014-03-01T08:18:29 < Jack3k3> right
2014-03-01T08:18:39 < emeb_mac> however - that text seems to say that when the codec is master you must supply it with sysclk
2014-03-01T08:18:54 < emeb_mac> which is equivalent to MCLK
2014-03-01T08:19:36 < Jack3k3> thats what i thought at first, but it says when codec in slave mode sysclk must be applied by application, and when in master mode sysclk applied by system
2014-03-01T08:19:40 < Jack3k3> terrible wording
2014-03-01T08:20:17 < Jack3k3> eitherway, i've tried every possible combination of MCLK enabled/disabled w/ the systems in different SlaveRx/MasterTx MasterRx/SlaveTx modes
2014-03-01T08:21:01 < Jack3k3> http://codepad.org/B8VJddsU <- thats for setting up the I2S3/SPI3 STM32 port as slave... I *think* it's correct but maybe I missed something

2014-03-01T15:49:45 < nine-tails> mr dongs where did you get those dolls
2014-03-01T15:50:01 < nine-tails> aka the "stm32" holders

2014-03-01T16:00:26 < madist> i never thought of it before!
2014-03-01T16:00:53 < madist> they check you when you enter an airplane, but nobody checks you when you leave the airplane!
2014-03-01T16:01:07 < madist> the next time i'm on a plane, i'm unscrewing some parts and taking them home with me.
2014-03-01T16:01:14 < dongs> yep
2014-03-01T16:02:08 < zyp> I remember a guy I travelled with once stole a seatbelt
2014-03-01T16:02:15 < zyp> because he wanted the buckle
2014-03-01T16:02:47 < madist> i should google some airplane blueprints.
2014-03-01T16:03:01 < madist> figure out how to gain access to the room with all the computers.

2014-03-01T16:04:09 < dongs> not very smart unless he stole it from soneone elses seat
2014-03-01T16:04:26 < zyp> well, I guess he took it after the plane landed
2014-03-01T16:04:34 < madist> maybe someone else stole it from *his* seat!
2014-03-01T16:04:35 < dongs> right, but i mean
2014-03-01T16:04:43 < dongs> if they're gonna start looking
2014-03-01T16:04:46 < dongs> they know who was sitting there
2014-03-01T16:04:50 < zyp> ah, right
2014-03-01T16:05:18 < madist> do you always sit in the seat that's allotted to you ?
2014-03-01T16:05:26 < zyp> no, you don't have to
2014-03-01T16:05:27 < madist> if the plane is not full, i always switch seats.
2014-03-01T16:06:13 < zyp> also, small flights tend to have free seating
2014-03-01T16:07:32 < dongs> stealing one from a eu>jp flight is probably a bad idea
2014-03-01T16:07:49 < dongs> i flew on this shit called "starflyer" to tokyo few days ago
2014-03-01T16:08:02 < dongs> i thought it was a LCC but the plane had huge lcd screens on eery seat and USB charge connector
2014-03-01T16:08:15 < dongs> and apparetly AC connectors but i didnt bother checking since int was only like 1hr flight

2014-03-01T16:11:20 < zyp> also, are you sure it were a usb charge connector?
2014-03-01T16:11:55 < zyp> I thought that was what I had on my flight to korea last year, so I plugged in my phone
2014-03-01T16:12:09 < zyp> http://bin.jvnv.net/f/2NiRE.png <- turned out it was an uncharge connector

2014-03-01T16:14:26 < zyp> I suspect the connector was for the media player, to hook up usb sticks with your own shit
2014-03-01T16:14:56 < dongs> hm sreen on this yoga thing kinda sucks
2014-03-01T16:14:59 < zyp> so it refused to give enough power to charge the phone much, while keeping the cpu running consuming power

2014-03-02T04:06:17 < dongs> right away
2014-03-02T04:06:29 < dongs> because fonts look like they were pulled out of someone's opensores ass
2014-03-02T04:08:47 < qyx_> pls

2014-03-02T04:36:28 < dongs> zyp: The TL2236B price is NT$54,000 (VAT not included), the TL2236 is discontinued $NT = TWD
2014-03-02T04:36:40 < dongs> tp: you must have not used windows since win95 then
2014-03-02T04:37:34 < zyp> dongs, what about RL2136/TL2136B?
2014-03-02T04:37:35 < tp> I havent used it since 1997, but unfortunately Ive seem it lots, and windows still looks like a child's toy to me
2014-03-02T04:37:53 < dongs> zyp, rl?
2014-03-02T04:37:54 < dongs> ok ill ask
2014-03-02T04:38:04 < zyp> TL*
2014-03-02T04:38:11 < dongs> non-B stuff is all discontinued I guess.
2014-03-02T04:38:23 < tp> dongs:  but each to his own, I still respect you for your knowledge about many things, even if you're a windows fanboy
2014-03-02T04:39:04 < GargantuaSauce> i am going to go ahead and point out that both fonts and font rendering engines are configurable on both platforms
2014-03-02T04:39:21 < dongs> GargantuaSauce: except lunix cant render fonts

2014-03-02T04:41:18 < dongs> enjoy getting  your lunix trash hacked daily
2014-03-02T04:41:32 < tp> yeah, windows isnt really useful, hence people don't do much with it
2014-03-02T04:41:36 < tp> hahahahahahahahahh
2014-03-02T04:41:54 < tp> how many windows viruses are there now, over a million ?
2014-03-02T04:41:58 < dongs> 99% of people using computers don't do anything. totally man.
2014-03-02T04:42:03 < tp> so true
2014-03-02T04:42:11 < dongs> tp, your virus argument is utterly worthless.
2014-03-02T04:42:15 < tp> ma and pa sixpack
2014-03-02T04:42:17 < dongs> virus writers target platforms people use
2014-03-02T04:42:18 < dongs> noone uses lunix
2014-03-02T04:42:21 < dongs> thus it has no viruses.
2014-03-02T04:42:21 < GargantuaSauce> yeah norton keeps me safe erryday
2014-03-02T04:42:22 < dongs> its pretty obvious
2014-03-02T04:42:40 < qyx_> ok, no more win vs. lin
2014-03-02T04:42:44 < tp> dongs:  your virus statement is probably older than you
2014-03-02T04:42:50 < zyp> qyx_, agreed
2014-03-02T04:42:57 < tp> qyx_:  no problem
2014-03-02T04:43:00 < dongs> tp, only becaues its true
2014-03-02T04:43:00 < zyp> it's not going to lead anywhere
2014-03-02T04:43:05 < qyx_> better recommend some good source for planar flyback transformers
2014-03-02T04:43:08 < tp> zyp:  so true
2014-03-02T04:43:36 < qyx_> i need to pack ~70W under 13mm height
2014-03-02T04:43:48 < tp> dongs will still be a windows fanboy and I'll still be a Linux zealot in 5 years, we wont change each other I iota
2014-03-02T04:44:13 < zyp> I used to like linux
2014-03-02T04:44:17 < tp> qyx_:  sounds pretty difficult
2014-03-02T04:44:19 < dongs> lunix will still be a joke in 5 yeras
2014-03-02T04:44:29 < zyp> then I switched to os x
2014-03-02T04:44:44 < gnomad> Personally, I've never seen a windows machine in the wild that wasn't completely infested with malware.
2014-03-02T04:45:07 < dongs> ive nefver seen a lunix machine that worked
2014-03-02T04:45:10 < zyp> gnomad, I haven't had much problems with malware on my windows machines
2014-03-02T04:45:12 < tp> yep, 10 minutes is all XP needs after a fresh install to be totally owned
2014-03-02T04:45:19 < dongs> my typical lunix usability test: pull your usb mouse while GUI is running
2014-03-02T04:45:21 < dongs> then try to do soemthing.
2014-03-02T04:45:24 < dongs> with keyboard only.
2014-03-02T04:45:26 < tp> and xp is *still* the most common OS on earth
2014-03-02T04:45:27 < gnomad> and running anti-virus/anti-malware software is generally worse than actually having one.
2014-03-02T04:45:30 < dongs> after failing, plug the mouse back in
2014-03-02T04:45:40 < dongs> when lunix can do this, lemme know
2014-03-02T04:45:55 < zyp> dongs, alt tab to command line, do everything from there?
2014-03-02T04:46:00 < zyp> :p
2014-03-02T04:46:01 < dongs> you cant evne plug a fucking mouse into a lunix without restarting or reocmpiling kernel
2014-03-02T04:46:05 < qyx_> dongs: it always worked
2014-03-02T04:46:17 < gnomad> can't say as I've ever had that problem
2014-03-02T04:46:20 < tp> Linux has run my business for the last 10 years, from it's start, obviously I have no issues
2014-03-02T04:46:52 < tp> but then I do *real* work, not just watch pron and sit on facebook all day
2014-03-02T04:47:51 < tp> dongs, that's just not so, I can unplug/plug a usb mouse anytime into any of my Linux boxes and they don't care
2014-03-02T04:48:04 < tp> I'll do it right now to this box ...
2014-03-02T04:48:21 < GargantuaSauce> he's actually referring to ps/2 i think, support for which was just disabled by default iirc
2014-03-02T04:48:38 < tp> gee still here
2014-03-02T04:48:40 < dongs> no im talking about usb mice and Xwindows.
2014-03-02T04:48:49 < GargantuaSauce> well you're incorrect then
2014-03-02T04:48:50 < qyx_> so your argument is invalid
2014-03-02T04:48:55 < tp> this is xchat on x windows
2014-03-02T04:48:56 < dongs> which need editing some bullshit config file, restarting X, etc.
2014-03-02T04:49:04 < qyx_> what
2014-03-02T04:49:16 < tp> nonsense, I cant believe Im hearing this from dongs
2014-03-02T04:49:24 < qyx_> static xorg.conf's were in fashion somewhen around 2000
2014-03-02T04:49:30 < gnomad> heh, you're thinking about X windows from 15 years ago.
2014-03-02T04:49:38 < tp> dongs:  did a Linux box hurt you as a child, molest you ?
2014-03-02T04:49:51 < tp> thats gotta be the reason
2014-03-02T04:49:52 < qyx_> even winxp at that time couldn't handle this

2014-03-02T04:50:20 < gnomad> WinXP *still* loses it's mind if you plug in a USB device before installing the drivers.
2014-03-02T04:50:21 < tp> dongs is thinking of XP, remember bill gates big demo ?
2014-03-02T04:50:30 < zyp> dongs, how much is TW VAT?
2014-03-02T04:50:42 < gnomad> Did they even fix that problem in vista/7?

2014-03-02T04:52:02 < dongs> zyp: 5%
2014-03-02T04:52:54 < zyp> ok, that puts it around the same cost as the .de distributor
2014-03-02T04:53:11 < zyp> except I'd have to pay norwegian VAT on top of that if I ordered from there
2014-03-02T04:54:12 < qyx_> from .de?

2014-03-02T04:54:53 < qyx_> i though you have some eu-import agreement or something like that
2014-03-02T04:55:02 < zyp> norway is not part of EU
2014-03-02T04:55:05 < qyx_> i know

2014-03-02T05:34:55 < zyp> no, seems to support bunch of stuff
2014-03-02T05:36:47 < dongs> what does it do? show wave from scope next to LA?
2014-03-02T05:37:00 < zyp> yes
2014-03-02T05:37:10 < dongs> i remember i installed tekvisa once for some similar shit, the crap installed garbage everywehre and I had to reinstall my machine

2014-03-02T05:40:43 < dongs> oo

2014-03-02T05:40:50 < dongs> cool
2014-03-02T05:41:13 < zyp> yes, you have to link them with a trigger cable
2014-03-02T05:41:43 < zyp> seems pretty useful when you're doing analog shit

2014-03-02T05:45:34 < dongs> simon could use that for esc testing
2014-03-02T05:45:48 < dongs> graph 3phase and bitbang some stuff
2014-03-02T05:45:57 < dongs> tho a regular 4ch scope would do that just as well
2014-03-02T05:46:12 < dongs> zyp: NT$36,000 for the other one
2014-03-02T05:46:14 < dongs> he jsut replied
2014-03-02T05:46:39 < Simon--> yah
2014-03-02T05:47:21 < Simon--> an MSO..
2014-03-02T05:47:36 < Simon--> oh. I was going to just do trigger out from one scope to the other
2014-03-02T05:48:01 < dongs> simon so rich now he can just cascade 4ch scopes all over hte place
2014-03-02T05:48:23 < Simon--> stack o ds1052e
2014-03-02T05:48:26 < dongs> haha
2014-03-02T05:48:30 < dongs> filth
2014-03-02T05:48:40 < zyp> ok, I guess I want the TL2236B then
2014-03-02T05:49:29 < zyp> 18M sounds a bit small, and if I'm going to spend a bunch of money, better spend it well
2014-03-02T05:50:02 < zyp> I just need this guy who is buying 75 boards from me to pay me first
2014-03-02T05:51:11 < zyp> oh, and I probably want to order another round of boards soon, I've only got 17 left now
2014-03-02T05:51:17 < dongs> haha, damn.
2014-03-02T05:51:34 < dongs> but sure , anytime. just fix teh connector holes :|
2014-03-02T05:51:43 < dongs> i dont wanan hear that shit from them for 3rd time.
2014-03-02T05:52:13 < zyp> can't they fix them themselves before fabbing the board, since they're complaining? :p
2014-03-02T05:52:44 < dongs> i wonder if standard drill ends upo being a couple mil less than your hole + plating
2014-03-02T05:52:47 < dongs> and it fucks up
2014-03-02T05:53:16 < dongs> i can tell pcb place to increase hole size by X if you tell me waht X is.
2014-03-02T05:54:24 < zyp> nah, I can fix it
2014-03-02T05:57:36 < aadamson> dongs, quick dt question... how do you put vias down on a specific net? I need to add an RF perimeter around an RF path and doing a static via, or more than one and then one at a time placing them on a net is  RPITA?
2014-03-02T06:00:30 < dongs> edit->edit selection -> vias -> unconnected,
2014-03-02T06:00:35 < dongs> then right click one of the selceted ones and add to net
2014-03-02T06:01:20 < aadamson> perfect... thanks... I'm really trying to like DT... I've done 4 boards in the last 2 days with it... to many old habits with eagle I think :)... but I"m trying

2014-03-02T06:08:02 < dongs> it has pretrigger yes
2014-03-02T06:08:13 < dongs> configurable as well as far asi  remember
2014-03-02T06:08:22 < zyp> how much? entire buffer if you wanted to?
2014-03-02T06:10:54 < dongs>  hmmm, wait im not seeing it. i thought it was somewhere
2014-03-02T06:11:43 < dongs> there's post-trigger size
2014-03-02T06:11:49 < dongs> looks like thats only possible on hardware triggers
2014-03-02T06:11:51 < dongs> 10-90%

2014-03-02T18:31:19 < zyp> what's that?
2014-03-02T18:31:47 < dongs> rs485?
2014-03-02T18:32:07 < dongs> at leastr i hope it is
2014-03-02T18:32:26 < zyp> looks pretty fast to be rs485
2014-03-02T18:32:40 < dongs> its using a fast driver
2014-03-02T18:33:07 < zyp> so that's a constant stream of 0x55 ?
2014-03-02T18:34:30 < dongs> clock
2014-03-02T18:34:37 < emeb_mac> maybe a constant stream of 0xF0
2014-03-02T18:34:41 < emeb_mac> really fast
2014-03-02T18:36:12 < zyp> ah, yeah, that would indicate a more normal baudrate
2014-03-02T18:36:22 < zyp> dongs, clock?
2014-03-02T18:36:27 < zyp> rs485 doesn't have a clock
2014-03-02T18:36:40 < dongs> it does when youre outputting a clock over it
2014-03-02T18:37:17 < zyp> right, so it's not rs485 at all, just a clock signal put through a rs485 transceiver to make it differential
2014-03-02T18:37:27 < dongs> y
2014-03-02T18:40:27 < Miek> i didn't think rs485 specified any protocol, speed, etc. anyway?

2014-03-02T19:32:09 < __rob> hello
2014-03-02T19:32:24 < __rob> can anyone tell me what exactly the bit-band region is for ?
2014-03-02T19:32:36 < __rob> the arm docs say "Bit-banding maps a complete word of memory onto a single bit in the bit-band region."
2014-03-02T19:32:42 < __rob> what use is that
2014-03-02T19:32:50 < __rob> why would I want a single bit that represents an entire word
2014-03-02T19:33:39 < gxti> the next two sentences tell you why
2014-03-02T19:35:35 < __rob> that doesn't make sense to me. A single bit that represents a 32bit word ?
2014-03-02T19:35:58 < __rob> so if I set the bit band bit to 1 it sets all 32 bits in its corresponding 32 bit word to 1 ?
2014-03-02T19:35:59 < __rob> or what
2014-03-02T19:36:05 < gxti> it's the other way around
2014-03-02T19:36:09 < gxti> a word that holds a single bit
2014-03-02T19:36:32 < __rob> ohh right
2014-03-02T19:36:36 < gxti> the reason being "It also allows individual bits to be toggled from C without performing a read-modify-write sequence of instructions."
2014-03-02T19:36:37 < __rob> ok, that does make sense
2014-03-02T19:41:54 < MrMobius> slightly OT but why dont they put that feature on every microcontroller ever made? even the 8051 could toggle individual bits on its ports. stuff like speeds up bitbanging so much.
2014-03-02T19:43:31 < RaYmAn> a guess could be address space limitation?
2014-03-02T19:43:47 < RaYmAn> Stm32 is 32-bit and doesn't exactly use a lot of it for ram, so there's loads of 'spare' :P
2014-03-02T19:44:27 < MrMobius> ya, on 32 bit chips it makes sense. i think it is useful enough to have its own opcode if that cant be mapped to memory
2014-03-02T19:44:33 < MrMobius> at least on a few of the ports
2014-03-02T19:44:35 < Rickta59> this vidoe explains how it works on a ti m4f and is not an stm32 chip but concepts explained are the same
2014-03-02T19:44:38 < Rickta59> http://www.youtube.com/watch?v=pQs8vp7JOSk&list=PLPW8O6W-1chwyTzI3BHwBLbGQoPFxPAPM
2014-03-02T19:44:52 < RaYmAn> stm32 also has something directly for gpios
2014-03-02T19:45:13 < __rob> so not all the peripheral registers seem to map to bitband addresses
2014-03-02T19:45:28 < __rob> AHB2 on my mcu is at 0x48000000
2014-03-02T19:45:46 < __rob> so that can't be written per bit ?

2014-03-02T20:28:53 < masa> does someone know how exactly the Boot to SRAM procedure goes on STM32 chips?
2014-03-02T20:30:00 < masa> the datasheet says that SRAM does not get aliased to 0x0000000 and that STM32 uses "speciel techniques" to enable boot to SRAM to work, but doesn't seem to specify how exactly that works
2014-03-02T20:30:53 < masa> I'm having some troubles with the early boot stuff, the PC doesn't seem to get set to the correct value
2014-03-02T20:32:04 < gxti> i haven't tried but there's some magic token in my vector table that might be related
2014-03-02T20:32:19 < masa> if I do "monitor reset halt" followed by "load" from gdb, and the reset the chip with hw, or do a "monitor reset halt" followed by continue, I get lockups
2014-03-02T20:32:50 < masa> but "monitor reset halt" followed by "load" followed by "continue" apparently works
2014-03-02T20:33:25 < gxti> https://my.st.com/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=https%3a%2f%2fmy.st.com%2fpublic%2fSTe2ecommunities%2fmcu%2fLists%2fcortex_mx_stm32%2fLast%20entry%20in%20vector%20table%20provided%20by%20ST%20startup%20scripts&FolderCTID=0x01200200770978C69A1141439FE559EB459D7580009C4E14902C3CDE46A77F0FFD06506F5B&currentviews=548

2014-03-02T20:35:58 < masa> thanks for the link, reading it atm
2014-03-02T20:36:50 < zyp> masa, why would you even use boot to sram?
2014-03-02T20:38:15 -!- barthess1 [~barthess@185.6.25.29] has quit [Ping timeout: 252 seconds]
2014-03-02T20:39:01 < masa> Well I guess I don't really have to use it, but I would prefer being able to at least run code loaded to SRAM when doing fast-paced testing/debugging with lots of recompiling and reprogramming
2014-03-02T20:39:45 < bvernoux> there is nothing magic for SRAM boot
2014-03-02T20:39:48 < bvernoux> see SYSCFG memory remap register (SYSCFG_MEMRMP)
2014-03-02T20:39:49 < masa> but I think Boot to Flash works too if I just link it to SRAM and then load with gdb and issue a continue(?)
2014-03-02T20:39:56 < masa> so wihtout doing a reset
2014-03-02T20:40:03 < masa> after the load at least
2014-03-02T20:40:37 < zyp> masa, which stm32 chip are you using?
2014-03-02T20:40:51 < bvernoux> if you want to execute code in SRAM you just need to map with linker the code in SRAM
2014-03-02T20:41:00 < bvernoux> and copy it at startup
2014-03-02T20:41:02 < masa> stm32vldiscovery board atm, so stm32f100rbt6
2014-03-02T20:41:16 < zyp> masa, ok, right
2014-03-02T20:41:41 < zyp> so you're using a chip with 20k sram
2014-03-02T20:41:42 < masa> bvernoux: yeah, that is what I expected as well. Just don't isue a reset or the pc gets messed up
2014-03-02T20:42:03 < bvernoux> I'm doing that on LPC43xxx
2014-03-02T20:42:11 < zyp> loading 20k to flash takes practically no time, and flash endurance is good enough for wear to not matter
2014-03-02T20:42:12 < bvernoux> as execution from SPIFI is ultra slow
2014-03-02T20:42:23 < bvernoux> but for STM32 flash is ultra fast and have a good cache
2014-03-02T20:42:24 < zyp> bvernoux, how about you stop being irrelevant?
2014-03-02T20:42:43 < zyp> lpc43xx have a completely different bootup system, so it's not relevant at all
2014-03-02T20:42:48 < masa> what do they promise for flash endurance btw?
2014-03-02T20:42:53 < bvernoux> zyp: the remap is same
2014-03-02T20:42:59 < bvernoux> zyp: like on any MCU !!
2014-03-02T20:43:00 < zyp> masa, 30k cycles IIRC
2014-03-02T20:43:12 < masa> nice
2014-03-02T20:43:33 < jpa-> so little? i remember >100k
2014-03-02T20:43:36 < zyp> spendig time loading code to sram on stm32f1 is a waste of time
2014-03-02T20:43:44 < masa> bvernoux: was the syscfg register from LPC or STM32?
2014-03-02T20:43:48 < zyp> so I suggest just don't.
2014-03-02T20:43:58 < bvernoux> masa: the reference i gave you is in STM32 Datasheet
2014-03-02T20:44:09 < masa> well I do also want to properly learn this chip as a whole
2014-03-02T20:44:11 < bvernoux> masa: it is what you want
2014-03-02T20:44:25 < bvernoux> masa: it is what is done during boot in internal ROM
2014-03-02T20:44:38 < bvernoux> masa: MCU check the pins and set the value in this register
2014-03-02T20:45:10 < zyp> masa, the trick is to just forget about all that remap stuff and whatnot, and link it for the area it will actually be located
2014-03-02T20:45:32 < bvernoux> zyp: If he want to start from flash he needs to know how that work
2014-03-02T20:46:17 < zyp> I'm pretty sure the addr 0 aliasing is vendor specific
2014-03-02T20:46:29 -!- Bird|otherbox [~Da@unaffiliated/htt-bird] has joined ##stm32
2014-03-02T20:46:29 < bvernoux> no it is very common
2014-03-02T20:46:35 < bvernoux> especially to remap vector table too
2014-03-02T20:46:56 < zyp> SCB_VTOR is generic, but unrelated
2014-03-02T20:47:27 < zyp> and the entire existence of SCB_VTOR makes other remapping stuff pretty useless
2014-03-02T20:48:16 < masa> all the examples I have seen use the 0x8000000 memory range when linking to flash, and the datasheet says that in boot to flash mode that area gets alaised to 0x0, so I'm assuming once it starts to execute from 0x0, it is actually reading from 0x8000000 the first(?) instruction and then the rest from the 0x8000000 range? or does it get hopped over during the first branches or something?
2014-03-02T20:48:19 < bvernoux> the remapping stuff is very useful to virtualize the addr
2014-03-02T20:48:30 < bvernoux> I think you do not really understand what it means behind ;)
2014-03-02T20:49:27 < masa> hmm actually no
2014-03-02T20:49:29 < bvernoux> you just need to have a specific boot code and you can copy/remap stuff in a transparent way because virtual addr for code is 0x0
2014-03-02T20:49:44 < masa> since the reset vector does the hopping to 0x8000000 range already, right?
2014-03-02T20:49:59 < bvernoux> so 0x0 could be executed in Flash like it is done at startup with Boot FLash
2014-03-02T20:50:08 < bvernoux> and then execute in RAM with same base addr
2014-03-02T20:50:35 < masa> still getting used to these datasheets, in which section is the syscfg register?
2014-03-02T20:50:59 < bvernoux> 9.2.1  SYSCFG memory remap register (SYSCFG_MEMRMP)
2014-03-02T20:51:05 < bvernoux> in RefManual
2014-03-02T20:51:16 < zyp> masa, at reset it loads initial sp and pc contents from 0x0 and 0x4 respectively
2014-03-02T20:52:05 < zyp> and when you have the entry vector at 0x4 pointing somewhere in 0x800xxxx, you've already ruled out the need for any more remap
2014-03-02T20:52:23 < masa> yeah, and if the program has been linked to 0x8000000 then the reset vector will actually transfer the execution from the 0x0 area to the 0x8000000 area in case of boot to flash?
2014-03-02T20:52:32 < zyp> exactly
2014-03-02T20:52:37 < masa> yeah

2014-03-02T20:54:09 < masa> bvernoux: yeah I was thinking about it too, just program the first couple of words in flash to aid in the boot to sram stuff
2014-03-02T20:54:39 < zyp> masa, if you want to do that, you can look at this: http://cgit.jvnv.net/arcin/tree/bootloader.cpp
2014-03-02T20:54:44 < bvernoux> masa: else you can also just map your code to execute in SRAM and copy it before

2014-03-02T20:54:58 < zyp> the chainload() command will jump to a new application wherever
2014-03-02T20:55:20 < zyp> by repointing SCB_VTOR to the new vector table, and grabbing new sp and pc contents

2014-03-02T20:57:29 < masa> horrible implementation? :p
2014-03-02T21:00:39 < PaulFertser> They have documented other horrible things in erratas.
2014-03-02T21:01:14 < zyp> PaulFertser, maybe because it's useless? :p
2014-03-02T21:01:14 < bvernoux> anyway the fun is @168MHz there is 6 cpu cycles for each Flash access
2014-03-02T21:01:26 < bvernoux> even if there is cache for Data and Instruction

2014-03-02T21:01:51 < bvernoux> i speak about real MCU => F4 ;)
2014-03-02T21:02:14 < zyp> keep in mind that the flash is 128 bits wide
2014-03-02T21:02:17 < PaulFertser> zyp: many people think that it's a nice idea to fix boot pins to boot from sram and to load firmware in there via jtag/swd for debugging. Why would they think otherwise?
2014-03-02T21:02:26 < zyp> that's as much as 8 instructions
2014-03-02T21:02:33 < bvernoux> yes 128bits but anyway on some code the latency could kill the perf
2014-03-02T21:02:39 < zyp> loading 8 instructions in 6 cycles should be fine :)
2014-03-02T21:02:50 < bvernoux> but for very specific code
2014-03-02T21:02:56 < bvernoux> which are bigger than cache ;)
2014-03-02T21:03:48 < bvernoux> also F4 have not dual bank ;)
2014-03-02T21:04:04 < bvernoux> so loading data and executing code in Flash could be also a problem (delay)
2014-03-02T21:04:46 < bvernoux> F42xx have dual bank

2014-03-02T21:05:59 < zyp> dual bank what?
2014-03-02T21:06:16 < zyp> I'm pretty sure f42x also only have one flash bank
2014-03-02T21:06:39 < bvernoux> there is dual bank feature
2014-03-02T21:06:55 < bvernoux> at least in RefManual v6
2014-03-02T21:07:11 < zyp> hmm, I'm looking at v5
2014-03-02T21:07:17 < bvernoux> 2 bank of 1MB
2014-03-02T21:09:03 < zyp> where does it say that?
2014-03-02T21:09:24 < zyp> the illustration on page 74 still only shows one path between FLITF and flash

2014-03-02T21:11:38 < zyp> sure, but that doesn't necessarily mean that both can be accessed in parallel
2014-03-02T21:11:51 < bvernoux> yes it means that
2014-03-02T21:11:55 < bvernoux> it is explained before
2014-03-02T21:12:08 < zyp> where?
2014-03-02T21:14:13 < bvernoux> it is true that towards Figure 4. Flash memory interface connection inside system architecture
2014-03-02T21:14:13 < bvernoux> (STM32F42xxx and STM32F43xxx)
2014-03-02T21:14:25 < bvernoux> we do not really see it is dual
2014-03-02T21:15:12 < bvernoux> else dual bank is good to read on a bank during the other is erased
2014-03-02T21:15:50 < bvernoux> especially to execute code in 1st bank and store data in the 2nd and write/erase without crashing the code execution in 1st
2014-03-02T21:16:21 < bvernoux> anyway I prefer SPIFI for that ;)
2014-03-02T21:16:30 < bvernoux> but not available on STM32Fxx
2014-03-02T21:17:00 < bvernoux> as embedded flash is very expensive vs just have SRAM and interface with SPIFI like LPC43xxx

2014-03-02T21:21:47 < bvernoux> the problem is to have something with LQFP or max BGA 256
2014-03-02T21:21:55 < emeb_mac> howdy bvernoux
2014-03-02T21:22:00 < zyp> hi emeb
2014-03-02T21:22:03 < emeb_mac> hows your little sdr board
2014-03-02T21:22:06 < emeb_mac> hey zyp
2014-03-02T21:22:28 < emeb_mac> been playing with the Zybo
2014-03-02T21:22:41 < zyp> how is it?
2014-03-02T21:23:01 < emeb_mac> It's OK so far. Interesting architecture
2014-03-02T21:23:16 < emeb_mac> it comes with a tiny Linux installed in QSPI flash
2014-03-02T21:23:23 < emeb_mac> but you can't do much with that
2014-03-02T21:23:30 < bvernoux> hmm VF6 Cortex A5 speed is only 500Mhz I would have thing it will be 1Ghz :(
2014-03-02T21:23:56 < zyp> A5 isn't designed for high performance
2014-03-02T21:23:59 < emeb_mac> there's Xillinux distro that's out there for Zedboard is more capable and has some good FPGA interfaces
2014-03-02T21:24:49 < bvernoux> zyp: ha yes only 1.6DMIPS/MHz
2014-03-02T21:25:13 < zyp> still more than any cortex-m
2014-03-02T21:25:15 < bvernoux> emeb_mac: I'm waiting my parallella with Zynq7020 ;)
2014-03-02T21:25:20 < bvernoux> should arrive soon
2014-03-02T21:25:26 < zyp> so am I
2014-03-02T21:25:46 < emeb_mac> wow - that's been in the pipe for a while
2014-03-02T21:25:49 < bvernoux> zyp: yes for double in hw and maybe VFP
2014-03-02T21:25:53 < zyp> I guess in kickstarter terms, soon means august :)
2014-03-02T21:25:59 < bvernoux> zyp: NEON stuff are nice
2014-03-02T21:26:10 < zyp> bvernoux, especially NEON LIGHTS
2014-03-02T21:26:13 < bvernoux> zyp: no mine should ship this month
2014-03-02T21:26:36 < zyp> bvernoux, it's kickstarter, they should all have shipped may last year :p

2014-03-02T21:30:57 < bvernoux> emeb_mac: ha nice and it is not too hot ?
2014-03-02T21:31:24 < bvernoux> emeb_mac: IIRC the Altera SOC is ultra hot when using FPGA + COrtexA9 at same time
2014-03-02T21:31:32 < emeb_mac> bvernoux: dunno - there's a plexiglass shield on the board so I can't touch the chip. :)
2014-03-02T21:31:33 < bvernoux> a bit like Xilinx
2014-03-02T21:31:47 < bvernoux> but you can measure it ;)
2014-03-02T21:31:49 < zyp> a bit like every high performance chip you mean?
2014-03-02T21:31:59 < bvernoux> zyp: not at 800MHz ;)
2014-03-02T21:32:14 < bvernoux> some are cold at such frequency
2014-03-02T21:32:31 < emeb_mac> really depends on what you're doing with it.
2014-03-02T21:32:33 < philpem> bleh, it's calling Balloc... bet my __sbrk implementation is broken :C
2014-03-02T21:33:11 < bvernoux> emeb_mac: The problem is to have free IP for basic stuff like DDR3 on FPGA
2014-03-02T21:33:12 < philpem> yeeeah, this thing's trying to access null pointers :C
2014-03-02T21:33:14 < emeb_mac> the zynq on the Zybo isn't particularly hot though
2014-03-02T21:33:50 < emeb_mac> bvernoux: AFAIK Altera has a hard macro for DDR3 in the Cyc V SoC
2014-03-02T21:34:05 < zyp> doesn't zynq also have that?
2014-03-02T21:34:16 < bvernoux> emeb_mac: Yes it was not the case for Cyclone 4 or 5 ...
2014-03-02T21:34:27 < emeb_mac> and all the basic interface stuff like AXI is free w/ Qsys
2014-03-02T21:34:32 < bvernoux> zyp: zynq seems to have the same for their SOC
2014-03-02T21:34:57 < zyp> as far as I've understood, zynq is capable of running the cortex-a without any fpga configuration loaded
2014-03-02T21:35:14 < emeb_mac> zyp: the altera can do that too
2014-03-02T21:35:15 < bvernoux> yes zynq FPGA and Cortex are not linked
2014-03-02T21:35:19 < bvernoux> there is 2 reset
2014-03-02T21:35:33 < bvernoux> even if internally they can be linked for logic stuff IIRC
2014-03-02T21:35:36 < emeb_mac> on our system we load the FPGA after Linux is boote
2014-03-02T21:35:46 < zyp> bvernoux, exactly, so that means that there is a hard core for the memory controlle
2014-03-02T21:35:58 < philpem> wheee, registers are trashed :C
2014-03-02T21:36:07 < bvernoux> yes hard core for memory controller on Cortex side
2014-03-02T21:36:20 < bvernoux> but on FPGA side i doubt it is a DDR3 hard core
2014-03-02T21:36:27 < emeb_mac> zyp bvernoux there are actually two memory systems on the Cyc V - one for the ARM, another for the FPGA
2014-03-02T21:36:39 < zyp> bvernoux, yes, and the configurable logic gets access to both a slave and a master port on the AXI matrix
2014-03-02T21:36:51 < bvernoux> when i speak about free IP it is about FPGA DDR3 side
2014-03-02T21:37:06 < zyp> so the fpga and arm can share the memory controller
2014-03-02T21:37:11 < bvernoux> I know on Cortex it is HW as the system could not start (or just using internal ram ;)
2014-03-02T21:37:24 < bvernoux> there is 2 mem controller
2014-03-02T21:37:31 < bvernoux> 1 for FPGA and 1 for Cortex
2014-03-02T21:37:43 < bvernoux> on both Xilinx Zynq and Altera SOC
2014-03-02T21:37:53 < emeb_mac> sounds right
2014-03-02T21:38:05 < zyp> emeb_mac, really?
2014-03-02T21:38:10 < bvernoux> else it will be a big problem ;)
2014-03-02T21:38:15 < emeb_mac> and you can do soft controller if the hard controller doesn't meet your needs
2014-03-02T21:38:17 < zyp> I thought it was shared
2014-03-02T21:38:18 < bvernoux> as DDR3 controller is not designed to be shared ...
2014-03-02T21:38:24 < bvernoux> by multi master
2014-03-02T21:38:34 < zyp> bvernoux, how would DMA work then?
2014-03-02T21:38:46 < bvernoux> DMA is a special controller ;)
2014-03-02T21:38:54 < zyp> it's a master
2014-03-02T21:39:02 < emeb_mac> bvernoux: the FPGA logic on the Cyc V SoC can access the ARM side memory
2014-03-02T21:39:02 < zyp> so then you have multiple masters.
2014-03-02T21:39:14 < bvernoux> ha ok nice
2014-03-02T21:39:30 < bvernoux> I was not thinking they have done such stuff in SOC
2014-03-02T21:39:48 < bvernoux> anyway it is just arbitration
2014-03-02T21:39:50 < zyp> http://www.xilinx.com/content/xilinx/en/products/silicon-devices/soc/zynq-7000/_jcr_content/mainParsys/xilinxcolumns_9aa7/column1/xilinximagemodal_331/image.img.jpg/1388706340885.jpg <- I mean, just look at this
2014-03-02T21:39:59 < emeb_mac> so you can have Linux set up a buffer in its own mem and then the FPGA can read it out etc
2014-03-02T21:40:22 < bvernoux> emeb_mac: Yes I just hope it is managed correctly ;)
2014-03-02T21:40:41 < emeb_mac> define "correctly"
2014-03-02T21:40:55 < bvernoux> that there is no cache effect
2014-03-02T21:41:23 < bvernoux> and you read old value, or even worse they have managed the fact CPU write data and at same time the FPGA read it ;)
2014-03-02T21:41:53 < emeb_mac> here's the same diag for the Altera parts: http://www.altera.com/devices/fpga/cyclone-v-fpgas/images/SOC_CycloneV.gif
2014-03-02T21:42:04 < bvernoux> yes nice
2014-03-02T21:42:11 < emeb_mac> one shared controller in the HPS and an other hard controller in the fabric
2014-03-02T21:42:12 < bvernoux> so the both SOC are very similar
2014-03-02T21:42:38 < emeb_mac> from the diag zyp posted the zynq seems to only have one mem controller
2014-03-02T21:43:06 < zyp> sounds like I didn't remember wrong then :)
2014-03-02T21:43:12 < emeb_mac> yep
2014-03-02T21:43:44 < bvernoux> yes Multiport DRAM controller
2014-03-02T21:44:21 < bvernoux> not really good which could be a major problem when both FPGA and Cortex will use exensively the DDR3

2014-03-02T21:44:54 < bvernoux> anyway we do not know how it is implemented in the Multiport DRAM controller maybe there is multiple controller
2014-03-02T21:44:55 < emeb_mac> Terasic now has a cheaper altera SoCkit: http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&No=836&PartNo=7
2014-03-02T21:45:05 < emeb_mac> only $199
2014-03-02T21:45:17 < bvernoux> Yes i saw that
2014-03-02T21:45:28 < zyp> emeb_mac, how's the altera tools vs xilinx?
2014-03-02T21:45:28 < bvernoux> but the Altera SocKIT is really better ;)
2014-03-02T21:46:03 < emeb_mac> zyp: both Altera and Xilinx SoC tools are pretty complex
2014-03-02T21:46:13 < emeb_mac> and difficult to use at first
2014-03-02T21:46:23 < zyp> I don't mean the SoC tools
2014-03-02T21:46:30 < zyp> but in general
2014-03-02T21:46:44 < emeb_mac> oh - ISE and Quartus are about equivalent
2014-03-02T21:47:03 < emeb_mac> both pretty complete, free and been around long enough that they're pretty stable
2014-03-02T21:47:10 < bvernoux> emeb_mac: DE1-SOC have only Slow Connector (just 2.54mm pins) instead of High End HSMC
2014-03-02T21:47:14 < zyp> I'd rather not mix code into this stuff, I already know how to handle code
2014-03-02T21:47:24 < zyp> :)
2014-03-02T21:47:48 < emeb_mac> bvernoux: the HSMC port is nice - we use that to interface to a high-speed ADC/DAC board
2014-03-02T21:47:52 < bvernoux> SockKIT is really better for just 100USD more
2014-03-02T21:47:52 < emeb_mac> for our SDR stuff
2014-03-02T21:47:54 < bvernoux> http://www.terasic.com.tw/cgi-bin/page/archive.pl?Language=English&CategoryNo=167&No=816
2014-03-02T21:48:05 < bvernoux> emeb_mac: yes HSMC is a must have

2014-03-02T21:49:44 < zyp> low pin count -> solder it at home in a frying pan
2014-03-02T21:50:01 < emeb_mac> that's the blunt way to say what I said
2014-03-02T21:50:29 < emeb_mac> bvernoux: yes, a low-end SoC would be good
2014-03-02T21:50:45 < emeb_mac> something you could use on a 4-layer PCB
2014-03-02T21:51:35 < zyp> I still want something in the cortex-m-range that looks more decent than smartfusion

2014-03-02T21:53:39 < zyp> yeah
2014-03-02T21:53:49 < emeb_mac> seems like a PSoC competitor
2014-03-02T21:54:37 < emeb_mac> Agree - a Cortex M4 + FPGA fabric + flash would be very nice
2014-03-02T21:55:42 < emeb_mac> put it in a LQFP144
2014-03-02T21:55:52 < zyp> or even smaller
2014-03-02T21:55:58 < emeb_mac> I could do a lot with that...
2014-03-02T22:01:23 < bvernoux> emeb_mac: yes the dreaming MCU ;)
2014-03-02T22:01:52 < bvernoux> especially to design special instruction in FPGA side and call them with special ARM instruction
2014-03-02T22:02:02 < emeb_mac> coprocessor interface

2014-03-02T22:02:13 < Bird|otherbox> yeah, strikes me as a job for the coprocessor I/F
2014-03-02T22:02:17 < bvernoux> yes the corpo stuff is available in ARM since M0
2014-03-02T22:02:29 < Bird|otherbox> it's older than that even
2014-03-02T22:02:32 < Bird|otherbox> a lot older :P
2014-03-02T22:02:33 < bvernoux> yes ;)
2014-03-02T22:03:06 < emeb_mac> IIRC there's some stuff in zynq to put the copro in the fabric
2014-03-02T22:03:36 < emeb_mac> dsp accelerator...
2014-03-02T22:05:47 < zyp> I don't see a huge advantage over just doing memory mapped stuff
2014-03-02T22:07:20 < bvernoux> emeb_mac: ha very nice
2014-03-02T22:07:31 < bvernoux> zyp: you can gain lot of cycles
2014-03-02T22:08:45 < zyp> I wouldn't be too sure about that
2014-03-02T22:09:39 < zyp> a «coprocessor call» instruction wouldn't be fundamentally different from a «store to memory» instruction in how they would be process
2014-03-02T22:10:03 < bvernoux> except you have register as input on copro call
2014-03-02T22:10:25 < zyp> str also takes a register as input
2014-03-02T22:12:22 < bvernoux> anyway I can also live with only memory mapped stuff ;)
2014-03-02T22:15:36 < bvernoux> emeb_mac: what is missing on Zynq or AlteraSOC is USB 3.0 ;)
2014-03-02T22:15:57 < bvernoux> or Eth 10Gb
2014-03-02T22:16:30 < zyp> what I'm missing is decently priced 10gbe in general
2014-03-02T22:17:00 < bvernoux> it is why USB 3.0 will be better ;)
2014-03-02T22:17:10 < bvernoux> maybe they shall wait USB 3.1 ;)
2014-03-02T22:17:28 < bvernoux> to immediatly have 10Gb/s
2014-03-02T22:17:29 < zyp> no, I mean, I want 10gbe between my computers here
2014-03-02T22:17:55 < bvernoux> but Eth 10Gb is expensive compared to USB 3.0
2014-03-02T22:17:56 < zyp> but when each card is $350, that's not happening
2014-03-02T22:18:16 < bvernoux> anyway Eth10Gb is more stable and faster than USB 3.1
2014-03-02T22:18:34 < zyp> bvernoux, yes, but usb 3 is fucking useless when I want to connect my desktop computer here to a server in the other end of the house
2014-03-02T22:18:58 < bvernoux> you can buy some optic fiber USB 3.0 haha ;)
2014-03-02T22:19:04 < bvernoux> up to 1Km IIRC ;)
2014-03-02T22:19:21 < bvernoux> one company sell such stuff very amazing
2014-03-02T22:19:26 < zyp> that still doesn't change the fact that you can't connect two usb hosts together.
2014-03-02T22:19:52 < bvernoux> yes not directly like Eth
2014-03-02T22:20:09 < zyp> so that does not solve my problem
2014-03-02T22:20:11 < bvernoux> and PC have not USB Device mode
2014-03-02T22:20:16 < bvernoux> only Host that does not help
2014-03-02T22:28:11 < qyx_> i assumed that usb3 allows that

2014-03-03T01:14:16 < Tectu> zyp, are you around?
2014-03-03T01:14:37 < zyp> yep
2014-03-03T01:15:20 < Tectu> I'm a bit confused....    std::string const& s    vs.   const std::string& s    where's the difference?
2014-03-03T01:15:34 < Tectu> I'm not sure which one I want
2014-03-03T01:15:35 < Tectu> :P
2014-03-03T01:15:46 < Tectu> I want to pass a string by reference and promise not to modify it
2014-03-03T01:15:48 < zyp> no difference
2014-03-03T01:16:13 < zyp> but consider this:
2014-03-03T01:16:13 < Laurenceb_> http://sine.ni.com/cms/images/casestudies/debtechb.jpg?size
2014-03-03T01:16:49 < zyp> const std::string* s; std::string const* s; std::string* const s;
2014-03-03T01:17:11 < Tectu> uhm
2014-03-03T01:17:14 < zyp> the former two are equivalent, just like in your case, but the latter is not
2014-03-03T01:17:37 < Tectu> the latter will get a copy and not modify the copy?
2014-03-03T01:17:44 < zyp> const after * means the pointer is const, while const before * means that the object pointed to is const
2014-03-03T01:17:53 < Tectu> ah
2014-03-03T01:18:01 < zyp> references are always const, so there is no const after &
2014-03-03T01:18:30 < Tectu> so the latter of the three you just showed... you'd get a copy of the pointer and it will not be modifiable?
2014-03-03T01:19:09 < zyp> the pointer will not be modifiable, just like a reference can't be made to point to something else after you've defined it
2014-03-03T01:19:17 < Tectu> I'm a bit confused by pointers vs. reference anway... Could you explain it in short words to a noob?
2014-03-03T01:19:26 < Tectu> afaik a reference can never be NULL where a pointer can?
2014-03-03T01:19:31 < zyp> but the object pointed to may of course, unless you write const std::string* const s; :p
2014-03-03T01:19:43 < zyp> that's not entirely true
2014-03-03T01:20:08 < zyp> nothing stops you from doing Foo& foo = *(Foo*)0;
2014-03-03T01:20:35 < Tectu> well
2014-03-03T01:20:37 < zyp> but anyway, in implementation a reference is a const pointer
2014-03-03T01:21:01 < zyp> which means that once defined, it can't be made to point to anything else
2014-03-03T01:21:13 < Tectu> ah. So you can just do    int& a    instaed of    const int* a   ?
2014-03-03T01:21:38 < zyp> and because of this, you don't need the normal pointer operations on it, so instead it behaves as a value wrt. accessing the referenced object
2014-03-03T01:21:49 < zyp> no
2014-03-03T01:22:08 < Tectu> so it's basically just for convenience?
2014-03-03T01:22:14 < zyp> int& a; would be something like int* const a;
2014-03-03T01:22:58 < zyp> the difference is that when you use the reference, it behaves as a dereferenced pointer
2014-03-03T01:23:26 < Tectu> aah
2014-03-03T01:23:36 < zyp> consider this: int i = 5; int& r = i; int* const p = &i;
2014-03-03T01:23:42 < Tectu> so     int& a;    can be used like     int b = a?
2014-03-03T01:23:47 < zyp> now r is pretty much equivalent to *p
2014-03-03T01:23:54 < Tectu> while    int *a;    would be    int b = *a;   ?
2014-03-03T01:24:03 < zyp> r = 7 and *p = 7 would be equivalent
2014-03-03T01:24:10 < Tectu> I see
2014-03-03T01:24:40 < Tectu> It's confusing :P
2014-03-03T01:25:03 < zyp> maybe at first
2014-03-03T01:25:20 < Tectu> so whenever I use a reference thing, it is by default const (I cannot modify the object it points to) and I can use it like a dereferenced pointer?
2014-03-03T01:25:45 < zyp> but it's a nice way to avoid copying objects while avoiding all the gotchas involved with pointers
2014-03-03T01:25:54 < zyp> no.
2014-03-03T01:26:00 < Tectu> :(
2014-03-03T01:26:16 < zyp> references are const pointers, not pointers to const
2014-03-03T01:26:47 < zyp> const std::string& would however be a reference to const, i.e. a const pointer to const
2014-03-03T01:26:52 < Tectu> ah, so     int& a;    I cannot modify the address to which a points but I can a = 5;   ?

2014-03-03T01:27:14 < zyp> exactly
2014-03-03T01:27:57 < Tectu> so when I want to write a function (method) which takes a vector and I want to promise that I won't modify it, I do    const std::vector<double>& foo    ?
2014-03-03T01:28:16 < Tectu> and then    fo.at(5) = 3.5;    would throw a compile time error?
2014-03-03T01:28:31 < Tectu> while I can read from it without any problems?
2014-03-03T01:29:19 < zyp> http://paste.jvnv.net/view/YkV8B <- consider this
2014-03-03T01:30:04 < Tectu> makes sense
2014-03-03T01:30:10 < zyp> yes, that should be about right
2014-03-03T01:30:54 < Tectu> I thank you for your time.
2014-03-03T01:31:11 < zyp> foo.at(5) would probably return you a const double& in that case
2014-03-03T01:31:23 < zyp> which would give you a compile time error
2014-03-03T01:31:42 < Tectu> 'probably'?
2014-03-03T01:32:05 < zyp> I don't remember the specifics, but I believe that's how it works :)
2014-03-03T01:32:32 < zyp> I don't state things as facts when I'm not sure they are facts ;)
2014-03-03T01:32:45 < Tectu> that doesn't happen often :P
2014-03-03T01:33:07 < Tectu> I'd have another c++ question if you allow (I try to get into it a bit). When I have an object/class that has some vector as a member, should I clear() it in the destructor?
2014-03-03T01:34:23 < zyp> no
2014-03-03T01:34:40 < zyp> the vector will be destructed as part of your destruction
2014-03-03T01:35:01 < zyp> I mean, when your object ceases to exist, the vector will also cease to exist
2014-03-03T01:35:16 < Tectu> I see, thanks
2014-03-03T01:35:34 < Tectu> so you usually don't do anything inside a destructor beside deleteing possible allocated memory?
2014-03-03T01:35:59 < zyp> depends on what you do
2014-03-03T01:36:06 < Tectu> of course :P

2014-03-03T01:36:39 < zyp> there are a couple of cool RAII tricks
2014-03-03T01:36:48 < zyp> like a mutex holder object
2014-03-03T01:37:17 < zyp> you construct it on stack inside a function to grab a lock, and when it goes out of scope, it's constructor unlocks the lock again
2014-03-03T01:38:08 < zyp> that way you don't have to remember to unlock it yourself before each possible return point of the function

2014-03-03T03:12:52 < aadamson> dongs another hopefully quick question... do you specify a solder paste shrink amount or solder mask expansion amount when you gen gerbers in DT?
2014-03-03T03:13:05 < aadamson> if how much do you usually use for both?
2014-03-03T03:14:02 < dongs> no. i just let stencil place do it
2014-03-03T03:14:50 < aadamson> so you just set both to 0 and let the stencil guys figure that out if needed?

2014-03-03T18:38:27 < __rob> can anyone tell me, if a section is marked as RAM in my linker script, is that still stored in flash on the chip and copied to RAM ?
2014-03-03T18:39:14 < PaulFertser> Unless it has all zeroes, I think yes.
2014-03-03T18:40:47 < __rob> so what actually does the copying ? I am looking at the startup script for my chip, and I don't see how it differentiates between sections marked as ram or rom and what needs that need to be copied to ram at runtime
2014-03-03T18:42:19 < __rob> there is .flash_To_ram_loop function in it, but I am confuse how that exactly works with the file linker outputs
2014-03-03T18:42:55 < __rob> or is this all perfromed by the crt ?
2014-03-03T18:44:51 < __rob> I am asking as the IDE i am using, emblocks, has generated 2 almost identical linker scripts with my project, One called stm32f051r4_flash.ld and one stm32f051r4_sram.ld - the only difference being the text section is marked as RAM in the sram script and ROM in the other
2014-03-03T18:45:45 < __rob> I am trying to figure out how this is mechanised, as surely in both cases the text section is stored in non volatile memory, and only in the > RAM section case it is copied to ram before execution

2014-03-03T18:49:06 < zyp> __rob, you're confusings sections and memory areas
2014-03-03T18:49:36 < zyp> you have two memory areas; flash and ram
2014-03-03T18:49:48 < zyp> and three main sections; .text, .data and .bss
2014-03-03T18:50:19 < zyp> .text is executable code and read-only data like string literals, it's stored in flash and executed/read from there when it runs
2014-03-03T18:50:27 < zyp> .bss is initialized data
2014-03-03T18:50:43 < zyp> the initial values are stored in flash and copied to ram during startup
2014-03-03T18:50:46 < zyp> uh
2014-03-03T18:50:51 < zyp> no, that's .data
2014-03-03T18:51:09 < zyp> .bss is uninitialized variables, it's initialized to zero during startup

2014-03-03T18:52:56 < jpa-> __rob: the copying is done by crt0
2014-03-03T18:53:00 < __rob> what difference does that make
2014-03-03T18:53:09 < __rob> one is copied by the crt, the other is not ?

2014-03-03T18:53:15 < __rob> and is executed from the sram
2014-03-03T18:53:16 < __rob> ?
2014-03-03T18:53:27 < __rob> sorry, executed from the flash
2014-03-03T18:53:37 < zyp> RAM/ROM are memory areas
2014-03-03T18:53:41 < jpa-> nothing is going to copy .text anywhere, if you put it in ram it only works once
2014-03-03T18:54:09 < __rob> ahh, ok right, so thats only valid for debugging ?
2014-03-03T18:54:13 < __rob> while the programmer is attached
2014-03-03T18:54:15 < zyp> my suggestion is just forgetting about the _sram script, it's useless in practice :)
2014-03-03T18:54:30 < jpa-> yeah
2014-03-03T18:54:38 < jpa-> you have tons of flash, why bother with code in sram?
2014-03-03T18:55:00 < __rob> I guess this is there to save write cycles perhaps on the flash
2014-03-03T18:55:06 < zyp> it's not a problem
2014-03-03T18:55:09 < jpa-> not really an issue
2014-03-03T18:55:15 < zyp> the flash is rated for 30k cycles or so
2014-03-03T18:55:22 < __rob> yea, just a guess that is what its for..
2014-03-03T18:55:30 < __rob> the project auto created both files
2014-03-03T18:55:48 < __rob> ok, so if I wanted to execute my code from sram, I would be exected to copy it there myself ?
2014-03-03T18:55:54 < zyp> yep
2014-03-03T18:56:30 < __rob> ok, great
2014-03-03T18:57:08 < __rob> Also, I was originally looking at these scripts to figure out how exactly I can allocate a variable so that it can be accessed through the bitband addresses
2014-03-03T18:57:30 < zyp> I suggest forgetting about bitbanding too :)
2014-03-03T18:57:37 < __rob> I see no mention of any reserved memory area in the linker script to stop things using those addresses, or reserve it for bitbanding
2014-03-03T18:57:49 < zyp> well, bitbanding doesn't work like that

2014-03-03T18:58:13 < zyp> bitbanding aliases the normal memory regions, so you can access anywhere in sram with bitbanding
2014-03-03T18:58:40 < __rob> I thought there was a specific block of memory that mapped to bits in another specific area ?
2014-03-03T18:58:48 < zyp> those addrs are outside the ROM/RAM regions, and your linker script will only place stuff in those regions
2014-03-03T18:58:57 < zyp> yep
2014-03-03T18:59:49 < __rob> ahh, that makes sense now
2014-03-03T18:59:50 < zyp> think of it like this: the entire address space is reserved, except those two regions
2014-03-03T19:00:24 < __rob> I assumed the bitband region fell somewhere in the RAM region
2014-03-03T19:00:34 < __rob> that wouldn't have made alot of sense now thinking about it
2014-03-03T19:00:43 < zyp> if you want to use bitbanding, you just allocate a variable like you normally would, but then transform that address to a bitband address
2014-03-03T19:01:03 < zyp> but in practice that'll just lead to a bunch of macro mess without much benefit
2014-03-03T19:01:33 < __rob> but, surely there is only a specific area of ram that can be accessed with the bitband addreses?
2014-03-03T19:01:36 < __rob> not the whole lot ?
2014-03-03T19:02:12 < zyp> why?
2014-03-03T19:02:49 < zyp> the bitband region is just an alias where each word corresponds to a single bit in the normal memory region
2014-03-03T19:02:53 < __rob> I thoguth I read that..
2014-03-03T19:03:01 < zyp> I forgot the word size, but it's probably 32 bits
2014-03-03T19:03:15 < zyp> so that means the bitband area would be 32 times larger than the memory it aliases
2014-03-03T19:03:22 < __rob> yup
2014-03-03T19:03:46 < zyp> the largest stm32 have 256 kilobytes of flash, you have a 4 gigabytes address space
2014-03-03T19:04:16 < zyp> the bitband region for that would be 8 megabytes, I'm sure you can afford that ;)
2014-03-03T19:04:55 < jpa-> what, the largest stm32 surely have 2MB flash :)
2014-03-03T19:05:01 < zyp> sram*
2014-03-03T19:05:08 < jpa-> ah :)
2014-03-03T19:05:22 < zyp> but I'm sure you can afford 64 MB for the flash bitband also ;)
2014-03-03T19:05:28 < jpa-> :)
2014-03-03T19:05:36 < __rob> so presumably the entirety of the peripheral registers and core registers should be addressable through bitbanding aliases ?
2014-03-03T19:05:49 < jpa-> yes
2014-03-03T19:05:53 < zyp> you don't want to access peripheral registers through bitbanding
2014-03-03T19:05:56 < jpa-> it should say in the manual
2014-03-03T19:06:02 < jpa-> zyp: sure you do?
2014-03-03T19:06:23 < __rob> I thought that would be the main thing I would want, such as the gpios etc..
2014-03-03T19:06:33 < __rob> incase they are changed inside the interrupt
2014-03-03T19:06:44 < zyp> gpios have their own mechanisms that work better than bitbanding
2014-03-03T19:06:45 < jpa-> nothing worse than regular read-modify-write from the hardware point of view, and atomic from the software point of view
2014-03-03T19:07:21 < zyp> jpa-, that's the thing
2014-03-03T19:07:37 < jpa-> but yeah, i've never found a real use for bitband
2014-03-03T19:08:16 < zyp> atomic flags in normal sram for multithreaded systems, I've heard
2014-03-03T19:08:38 < jpa-> but for that purpose, wasting 32 bits per flag and just using bool would rarely matter..
2014-03-03T19:08:59 < zyp> true
2014-03-03T19:09:12 < __rob> I really just wanted to try it out and see how it works. I've always gone down the route of state machines in the main loop and just setting flags in the inturrupts.. at least with pic
2014-03-03T19:09:24 < zyp> and ldrex/strex is a better way to deal with atomic accesses anyway
2014-03-03T19:09:35 < jpa-> does bitband work with dma? is it done in the bus multiplexer or inside cpu?
2014-03-03T19:09:45 < zyp> inside cpu
2014-03-03T19:09:51 < zyp> it's a cpu feature
2014-03-03T19:09:52 < jpa-> so no use for that either
2014-03-03T19:09:57 < zyp> correct

2014-03-03T19:11:01 < zyp> the main thing that would make bitbanding useful is if the compiler could substitute single bit read-modify-write instructions with a bitband access as an optimization, instead of you having to deal with it in the source
2014-03-03T19:12:16 < zyp> oh, by the way, I checked the TRM
2014-03-03T19:12:19 < MrMobius> unless ou are trying to bitbang and need to count cycles
2014-03-03T19:12:49 < zyp> there are two bit band regions, each are 32MB and thus an alias for 1MB
2014-03-03T19:14:12 < __rob> so potentially on a larger chip, the whole sram couldn't be accesses through bitband regions ?
2014-03-03T19:14:32 < zyp> so 0x20000000-0x200fffff and 0x40000000-0x400fffff is available through bitband
2014-03-03T19:14:54 < zyp> __rob, let me know if you find a cortex-m with more than 1MB sram :)
2014-03-03T19:15:16 < zyp> I believe the largest one I've seen have something like 384k
2014-03-03T19:15:28 < __rob> yea, ok
2014-03-03T19:15:45 < __rob> and I suppose they could just expand the bitband region if a larger chip came along

2014-03-03T20:15:48 < trepidaciousMBR> zyp: I used a register for that, can't remember why that seemed better ;)
2014-03-03T20:16:21 < zyp> aren't registers cleared on reset?
2014-03-03T20:18:49 < trepidaciousMBR> zyp: The backup registers for the RTC are left alone, there are quite a few of them. Actually I remember now - that was why I used them, I couldn't find anything that stated categorically that the SRAM would retain contents on reset, but for those registers it is guaranteed
2014-03-03T20:19:01 < trepidaciousMBR> zyp: Probably just because I missed something in the datasheet though ;)
2014-03-03T20:21:48 < zyp> I considered using the backup registers, but I concluded it was too much hassle
2014-03-03T20:23:45 < trepidaciousMBR> It's not too bad as long as you only need a few values, if it's any help it does seem to work fine (so far...) ;)

2014-03-04T00:39:12 < Jack3k3> hey can anyone explain how audio codec chips communicate over i2s? specifically, my chip say it has 24bit data paths for the adc and dac parts
2014-03-04T00:39:44 < scrts> it's the same data, except serialized
2014-03-04T00:40:05 < Jack3k3> but the selections available for the data output interface are: I2S, LSB-justified 16bits, lsb justified 18bit, lsb justified 20 bits, msb justified
2014-03-04T00:41:20 < Jack3k3> say I set it to the i2s bus format, does that mean if I set the i2s Dataformat field to 16bit it will receive 16bit values,
2014-03-04T00:41:41 < Jack3k3> similarly if i change the dataformat to 24bit it will receive the full resolution 24bit value

2014-03-04T01:00:16 < tp> and I did buy a new Rigol 70Mhz DSO (2Gs/s)
2014-03-04T01:03:21 < Tectu> fancy, congratz
2014-03-04T01:06:59 < tp> yeah, havent used it yet, only looked at the lovely colors and functions!
2014-03-04T01:07:31 < gxti> i should sell my instek and get something fancier. but then again, there's stuff i need more than that...

2014-03-04T02:18:15 < tp> gxti:  my current DSO is a HP I bought in 1994 for $4500 demo price. It's '100Mhz', 20Mbps sample rate and has Tetris, and the usual load of front end noise only canceled by integration
2014-03-04T02:20:06 < dongs> Jack3k3: what.
2014-03-04T02:20:18 < dongs> Jack3k3: how does the chip have anything to do with the fact that you can't properly debug shit? :)
2014-03-04T02:20:28 < tp> gxti:  it failed after 5 years, and HP said they had no parts as they 'dispose of spare parts when the model is 5 years old'. I found another mobo for it on eBay after another 3 years, and it's been going ever since, but the Rigol, whilst being more 'menu driven, and nested menues etc' rather than driven by the usual easy scope knobs, leaves the old HP for dead
2014-03-04T02:20:59 < Jack3k3> dongs i duno man, after a week of working on this i have had zero indications of getting any type of data from the DAC on this guy
2014-03-04T02:20:59 < dongs> have you done all the testing needed before you give up? test tx only, test rx only, confirm both work, then rtfm and get fullduplex working? :)

2014-03-04T02:21:07 < tp> gxti:  the Rigol is 1/6 the price and 100 times faster
2014-03-04T02:21:13 < dongs> rigol is also shit
2014-03-04T02:21:20 < dongs> but I s uppose less shit than a HP shit from 1994
2014-03-04T02:22:02 < Jack3k3> dongs i created a version of the code with RX only, no dma, an its still fucked... only thing left for me to try is hook up the thing to the i2s2_ext and try to get full duplex working like emeb did.
2014-03-04T02:22:05 < dongs> Jack3k3: did you get a proper debugger dongle yet, so you can step and see peripheral registers and shit?
2014-03-04T02:22:15 < dongs> Jack3k3: yes, do that. thats how it should be anyway.
2014-03-04T02:22:19 < tp> yeah, I dream of a new http://teledynelecroy.com/oscilloscope/oscilloscopeseries.aspx?mseries=341 and marrying Uma Thurman, but theyre both only dreams at this point
2014-03-04T02:23:00 < Jack3k3> dongs: im going to get one yes, and im only running it via i2s2/i2s3 because thats how the waveshare fuckers setup the board connections
2014-03-04T02:23:05 < tp> dongs:  in 1994, the HP was impressive and affordable
2014-03-04T02:23:33 < dongs> Jack3k3: right, but if they set it up like that then it definitely works.
2014-03-04T02:23:40 < tp> dongs:  any DSO that is $1000 new *should* be shit, but the Rigol isnt bad
2014-03-04T02:23:47 < dongs> right
2014-03-04T02:24:08 < tp> you get what you pay for, be it a car, scope, rifle, whatever
2014-03-04T02:24:23 < Jack3k3> dongs: perhaps but I also asked them if they had ANY example code about the ADC and they had nothing, all there examples only show using I2S2 as TX for outputting audio with the DAC
2014-03-04T02:24:25 < dongs> i'm still thinking of getting tek MDO4054B or something this ye ar
2014-03-04T02:25:37 < dongs> i have dpo4034 and a 3ghz spectrum analyzer, so i could sell both to justify the price, but problem is i'd probably end up taking it off the bench more often due to integrated RF stuff, which I currently deal with by lugging heavy agilent analyzer around
2014-03-04T02:25:38 < tp> hah! that's just a Rigol copy ;-)
2014-03-04T02:25:48 < dongs> you wish
2014-03-04T02:25:51 < tp> hehe
2014-03-04T02:25:52 < dongs> rigol cant touch this stuff
2014-03-04T02:26:29 < tp> my first scope was a Tektronix 900 something, a real POS back in the 70's
2014-03-04T02:26:52 < tp> but yeah, Tek is high end, I've always worshipped them
2014-03-04T02:27:27 < tp> was tempted to get a secondhand Tek dso from the USA, but the shipping is a killer, and if it's DOA, too bad, so sad
2014-03-04T02:28:54 < tp> the rigol was $1000, and I think it's worth $1000 actually, but to get better, Id have to spend $5k upwards, and cant justify that at the moment
2014-03-04T02:29:25 < tp> dongs hates Rigol because they run embedded Linux and not WINCE
2014-03-04T02:33:46 < dongs> my tek is running lunix :(
2014-03-04T02:34:00 < dongs> on some mips shit

2014-03-04T02:34:54 < tp> and a xserver ?
2014-03-04T02:35:41 < dongs> no, fbcon
2014-03-04T02:35:43 < tp> best LA I ever had was a demo Tek with color lcd shutter, we paid $12k for it if I recall correctly, back in 1997
2014-03-04T02:35:45 < dongs> i think, i dont remember
2014-03-04T02:36:03 < tp> man, I loved that Tek
2014-03-04T02:36:15 < dongs> i only know beacuse i was looking at firmware to make a license key for all the protocol decoders
2014-03-04T02:36:24 < tp> aha
2014-03-04T02:36:40 < dongs> which i did, still lol each time i see one protocol key selling for liek $500 on ebay
2014-03-04T02:36:59 < tp> wow
2014-03-04T02:38:06 < tp> my Rigol has all the protocol decoders running for another 5000 hrs before they self destruct, hopefully someone will find a key for that model (latest)

2014-03-04T02:40:21 < tp> expensive
2014-03-04T02:41:44 < tp> how about a nice TEKTRONIX  MDO4054B-6 ? only $21k .....
2014-03-04T02:42:09 < dongs> yeah. was thinking either that or 3ghz. might go for 6 since otherwise it wouldn't be much of an upgrade from my current setup
2014-03-04T02:42:44 < tp> might pay to wait a while longer ?
2014-03-04T02:42:53 < dongs> yep or that.
2014-03-04T02:42:57 < dongs> -B just came out, too
2014-03-04T02:43:04 < dongs> with "much improved rf performance"
2014-03-04T02:43:20 < dongs> wonder what the tossers who paid for non-B version think
2014-03-04T02:43:27 < tp> in my case, 20msps to 2Gsps was a worthwhile step up, no question
2014-03-04T02:43:30 < ds2> what do you use the 3GHz-6GHz for?
2014-03-04T02:43:36 < dongs> i dont, thats why
2014-03-04T02:43:59 < ds2> can't think of a good use for that range
2014-03-04T02:44:01 < tp> the old HP on single shot with 20Msps was a frigging joke
2014-03-04T02:44:08 < ds2> do they come with near field probes?
2014-03-04T02:44:21 < dongs> i have some
2014-03-04T02:44:31 < tp> ds2:  5.8Ghz WiFi work ?
2014-03-04T02:44:41 < ds2> u built it?
2014-03-04T02:44:55 < ds2> tp: do you actually work with that?
2014-03-04T02:45:27 < dongs> probes are some crap from ETS EMCO or something. duno. got as bonus with spectrum analyzer
2014-03-04T02:45:50 < ds2> ah
2014-03-04T02:46:12 < dongs> http://www.ets-lindgren.com/7405 this is in my g oogle history
2014-03-04T02:46:15 < dongs> so it must be them
2014-03-04T02:46:33 < Jack3k3> so in arm lpc systems, I2S has something like a stereo/mono option, STM32 doesn't have this?
2014-03-04T02:47:41 < tp> ds2:  I don't work with 5.8Ghz WiFi design, but I configure, sell and handle Ubiquiti 5.8Ghz wifi gear every day
2014-03-04T02:47:42 < dongs> Jack3k3: no, it only does stereo
2014-03-04T02:48:06 < dongs> just discard the bits  you dont want
2014-03-04T02:48:15 < dongs> you're dmaing full 32 bits from the i2s peripheral anyway.
2014-03-04T02:48:55 < Jack3k3> thats confusing to me, the codec has two adc's, so does havinga  24bit datapath mean each gets 12bits?
2014-03-04T02:49:14 < dongs> i dont know, does the datasheet say so?
2014-03-04T02:49:20 < dongs> man, clive1 is fucking awesome
2014-03-04T02:49:34 < dongs> <clive1> if it were my problem I'd experiment.
2014-03-04T02:52:10 < Jack3k3> "the uda1380 supports i2sbus data format with word lengths of up to 24bits" thats all ive found
2014-03-04T02:53:05 < dongs> 'word' is one sample.
2014-03-04T02:53:11 < dongs> which makes sense, its probably a 24bit codec
2014-03-04T02:53:27 < Jack3k3> yeah it says "24-bit data pathf or AD and DAC" under features
2014-03-04T02:57:34 < Jack3k3> it seems to me if i setup the i2s in 24bit mode that ill get two consecutive samples, first left, second right, ill go back and see if i get anything usable with this

2014-03-04T03:31:16 < dongs> yes, lkeft/right depends on word select or whatever
2014-03-04T03:36:37 < dongs> why bother with 24bit tho? oprety sure in that mdoe you'd have to be reading full 32bit from i2s and discarding msb
2014-03-04T03:38:28 < Jack3k3> yeah i figured i would (ignoring the dma for now) when an interrupt is triggered, the handler grabs the received 32bit value and saves the 24bit lsb and then reads a second 32bit value to get the 24bit right channel
2014-03-04T03:38:44 < Jack3k3> but youre right i can do 16bit too
2014-03-04T04:13:03 < dongs> did you get a proper debugger yet

2014-03-04T04:40:26 < Jack3k3> I know it's triggering fine because my lcd is continously printing random numbers

2014-03-04T04:42:37 < englishman> Buy discovery, install keil
2014-03-04T04:42:39 < Jack3k3> dongs i thought printf would just deadlock your system if stdout is using interrupts
2014-03-04T04:43:23 < dongs> you know you're sending out ONE sample right
2014-03-04T04:43:26 < dongs> once every like 5 minutes
2014-03-04T04:43:29 < dongs> do you expect to hear it or wat
2014-03-04T04:43:30 < englishman> Or get the $20 stlink
2014-03-04T04:44:06 < dongs> does I2S irq really  trigger on each byte?
2014-03-04T04:44:09 < dongs> er word
2014-03-04T04:44:29 < Jack3k3> dongs i have the input to the codec grounded, ii was expected to be able to read the number off the lcd as being -32768 or something near that
2014-03-04T04:44:37 < Jack3k3> but it jsut jumps all over the place
2014-03-04T04:45:08 < dongs> try averaging it over say 100 samples.. ?
2014-03-04T04:45:14 < dongs> even running average.
2014-03-04T04:46:04 < Jack3k3> no i guess i can try, im just surprised its doing like -5000,3,33000,1400, -18000
2014-03-04T04:46:10 < Jack3k3> just really random
2014-03-04T04:48:10 < Jack3k3> "for transmissiong, each time an MSB is written to spi_Dr, the TXE flag is set and its interrupt is generated to load SPI_DR with the new value to send. For reception, the RXNE flag is set and its interrupt is generated whent he first 16MSB halfword is received"
2014-03-04T04:51:17 < dongs> i would just use DMA to rule out anything really dumb
2014-03-04T04:51:33 < dongs> and average buffer in dma_tc interupt
2014-03-04T04:51:37 < dongs> and print it i guess.
2014-03-04T04:51:39 < dongs> if you have no other choice.
2014-03-04T04:51:57 < Jack3k3> thing is ive been doing dma this entire time, just recently decided to try without it

2014-03-04T05:29:04 < Jack3k3> yeah so i removed the printf bullshit from the irq , basically all i do in the irq is receive send and increment a count variable..
2014-03-04T05:29:10 < Jack3k3> turns out the interrupt is actually not triggering
2014-03-04T05:29:40 < Jack3k3> back to square one, nothing is getting received via i2s3
2014-03-04T05:31:46 < dongs> did  you enable its clock
2014-03-04T05:31:49 < dongs> did  you enable the interrupt

2014-03-04T05:50:05 < Jack3k3> i really really am at a loss, this means i have not once successfully received Anything from the codec
2014-03-04T05:51:13 < dongs> and you've configured it (i2c) properly to output stuff?
2014-03-04T05:51:29 < dongs> and you have shit on i2s3 bus when you scope it?
2014-03-04T05:51:30 < dongs> etc.
2014-03-04T05:54:10 < Jack3k3> the i2c only thing you can set is Slave/Master mode (Slave), Data output (I2S standard),and ADC clocks enable.. On the I2S3_WS pin I have a nice 48khz squarewave

2014-03-04T08:20:00 < Jack3k3> blah guys i have literally gotten up at 8am and worked most of the day , everyday for the past week on this, and am no further ahead than when i started

2014-03-04T08:20:14 < dongs> its gotta be something real dumb then
2014-03-04T08:20:17 < dongs> thats usuall the case.
2014-03-04T08:20:38 < tp> Jack3k3:  just take a break, get a fresh perspective but keep at it, you'll find the reason
2014-03-04T08:20:42 < Jack3k3> it probably is honestly but everyday i come up with some new ideas, try it, and theres never anything positive to come from it
2014-03-04T08:21:25 < tp> go to the cinema, drop round dongs place and smoke a half a dozen cones, chill out, then get back to it
2014-03-04T08:21:49 < Jack3k3> i mean is it at all possible there was something wrong with the chip I got? I mean i know it seems insane but ive never gotten any output on the chip datao pin

2014-03-04T08:22:12 < tp> easy to find out, but another chip of the same type
2014-03-04T08:22:15 < tp> buy
2014-03-04T08:22:27 < Jack3k3> yeah
2014-03-04T08:22:47 < tp> look at it this way, youve got a weeks expertise on that chip now, and thats worth a lot
2014-03-04T08:23:02 < tp> once you find the problem, you'll be a expert with that part
2014-03-04T08:24:00 < tp> glamorous women from all over the world will want to meet you and have you look at *their* chip, you'll be dongs hero for solving it !
2014-03-04T08:24:22 < Jack3k3> yeah i guess, but i could also just use the codec chip used here http://ebrombaugh.studionebula.com/synth/stm32f4_codec/ that has actual working code
2014-03-04T08:24:53 < tp> yeah, but then you'll have wasted that week
2014-03-04T08:25:23 < tp> and I agree with dongs, how does changing hardware solve anything ?
2014-03-04T08:25:33 < Jack3k3> sort of yeah, though im much more familiar with the stm32 and i2s/i2c now which is a plus
2014-03-04T08:25:37 < tp> you have no guarantee that you wont waste another week on another chip
2014-03-04T08:25:57 < tp> exactly
2014-03-04T08:26:10 < tp> it's *never* a wasted week, you're learning all the time
2014-03-04T08:26:40 < tp> in fact when everything 'just works' (and we know that only happens with Linux) you don't learn much, cause it's easy
2014-03-04T08:27:42 < Jack3k3> yeah fair enough fair enough, i agree, im just super annoyed that the easiest and first most basic part of my big project is being a huge pain in the ass
2014-03-04T08:27:56 < tp> <Jack3k3>you just need a new perspective, take a break, don't think about that chip for 24 hrs, do something else
2014-03-04T08:28:14 < Jack3k3> like theres only so many ways you can config a codec chip via i2c and communicate audio w/ i2s on it..
2014-03-04T08:28:21 < Jack3k3> but yea break would probably be good
2014-03-04T08:28:26 < tp> it may be you?
2014-03-04T08:28:36 < tp> hell, when stuff doesnt work, it's always me
2014-03-04T08:28:40 < GargantuaSauce> okay just at a random glance and you've probably already dicked with it, but is there any chance the clock output on SPI3 should actually be enabled
2014-03-04T08:29:11 < GargantuaSauce> yes i can vouch for the PEBKAC almost always being the case
2014-03-04T08:29:15 < Jack3k3> oh I don't doubt that it's me but I would like to place the blame elsewhere :p
2014-03-04T08:29:35 < tp> I wrote some Perl code the other week, it was total crap, I couldnt even fix it it was so bad, a week later I deleted it and started again, now it's perfect, just a change of outlook was all it took
2014-03-04T08:31:43 < Jack3k3> GargantuaSauce, yeah thats kinda a huge annoying topic. 1) my uda1380board has a little jumper that connects the chip sysclk to either i2s2_mclk or i2s3_mclk, except, the silkscreen/schematic was incorrect and the pins were switched 2) the way i have it setup now, the uda1380 uses SPI2_MCLK but theres also modes where you can have the sysclock generated from the WSI clock, etc
2014-03-04T08:32:00 < GargantuaSauce> oh boy
2014-03-04T08:32:02 < Jack3k3> short answer: yes ive dicked with it more than i can reasonably type haha
2014-03-04T08:32:47 < GargantuaSauce> okay note #2. i have not done i2s but i know when the spi peripheral is using an external clock it should be in slave mode
2014-03-04T08:33:29 < GargantuaSauce> (and the clock needs to be driven by the external thing which in this case i guess is...the other spi periph)
2014-03-04T08:33:57 < GargantuaSauce> but that might be totally wrong for i2s i dunno
2014-03-04T08:34:06 < GargantuaSauce> shots in the dark here
2014-03-04T08:34:18 < Jack3k3> well in this case I2S2 (TX master) provides MCLK, SDA, WSI, BCLK and I2S3 (RX master) provides WSI + BCLK and the peripheral returns with SDA
2014-03-04T08:34:21 < tp> and who knows, could the pcb be in error ?
2014-03-04T08:34:31 < tp> anyone can make a mistake
2014-03-04T08:34:54 < GargantuaSauce> right ok i forgot the master and serial clocks were separate
2014-03-04T08:35:13 < GargantuaSauce> \(O_o)/ i reiterate my suggestion for destruction
2014-03-04T08:35:42 < Jack3k3> tp its possible, its a breakout board from waveshare , but like i said they already messed up the schem/silk screen. Also on their schematic the pin number they used were for an alternate form of the chip tahts not actually on the board despite the schematic showing the correct board number
2014-03-04T08:35:52 < tp> I knew two programmer who spent a year on a complex Forth robotics project. after 12 months the manuf of the chip (Rockwell) told them there was a 'typo' in the chip microcode that caused their problem ... oops
2014-03-04T08:36:09 < Jack3k3> I did manually trace/check with dmm that the data pins are at least connected to the right headers though
2014-03-04T08:36:17 < GargantuaSauce> yeah it really sounds like you're swimming in far too many unknowns
2014-03-04T08:36:22 < tp> Jack3k3:  thats a start
2014-03-04T08:36:35 < GargantuaSauce> again, LA and debugger are needed stat
2014-03-04T08:36:51 < Jack3k3> yeah should be here fri/sat

2014-03-04T08:37:16 < GargantuaSauce> because anything you can do in the meantime for empirical analysis is completely primitive by comparison to those tools
2014-03-04T08:37:29 < Jack3k3> yeah
2014-03-04T08:37:29 < tp> Jack3k3:  just get back to basics *after* you take a break, check the pins go to the right chip pins, print the schematic and meter out the connections, trace the checked ones in highlighter on your schematic
2014-03-04T08:38:10 < Jack3k3> also it doesn't make it any easier that my analog tek scope is not triggering well anymore =[
2014-03-04T08:38:14 < Jack3k3> tp yeah good idea
2014-03-04T08:38:41 < tp> no, thats a pain, but analog scopes never triggered well on non repetitive waveforms
2014-03-04T08:38:58 < tp> even trigger holdoff is only so useful
2014-03-04T08:39:07 < Jack3k3> yeah true true
2014-03-04T08:39:31 < tp> a decent debugger would be handy
2014-03-04T08:39:37 < tp> *very* handy
2014-03-04T08:39:43 < Jack3k3> ive got a usb scope that sorta works, i was able to atleast verify my 11mhz clock signal tho the waveform looked pretty shitty cause of the sampling on that thing
2014-03-04T08:39:51 < tp> then you can check register values are what they should be etc
2014-03-04T08:40:00 < Jack3k3> yeah that will be nice
2014-03-04T08:40:21 < Jack3k3> until now ive been using my lcd screen to flash colors for debugging lol
2014-03-04T08:40:32 < tp> plus it could be as simple as a crappy waveform for one reason or another, perhaps timing issues
2014-03-04T08:41:13 < tp> one needs decent test gear, or a lot of time to think and reason out the problem with ones mind
2014-03-04T08:41:43 < tp> it *could* be a faulty chip, but it's highly unlikely
2014-03-04T08:42:02 < Jack3k3> yeah, really unlikely since i can play audio with it, just never receive anything from it
2014-03-04T08:42:04 < tp> unless you damaged it during development somehow
2014-03-04T08:42:18 < Jack3k3> i wouldnt put that past me heh
2014-03-04T08:42:46 < tp> best to say 'just never seem to receive anything from it', until you know for sure :)
2014-03-04T08:43:06 < tp> rely on data, not intuition
2014-03-04T08:43:49 < Jack3k3> well so far i technically havnt since theres nothing happening on the SD line
2014-03-04T08:44:00 < Jack3k3> but yea theres other potentials for whats causing that
2014-03-04T08:44:22 < tp> I find, when I'm 'stuck' like you seem to be, and all my possibilities are exhausted, it's time to take a break, then find a way to run new tests, look at the problem from a different perspective
2014-03-04T08:45:38 < Jack3k3> yeah thats a good idea
2014-03-04T08:45:44 < Jack3k3> i will do so
2014-03-04T08:45:53 < tp> cool
2014-03-04T08:46:05 < Jack3k3> and im going to begin by going to sleep heh. thanks for the advice guys

2014-03-04T08:53:10 < tp> as a electronics tech, Ive followed a zillion wrong 'clues' fixing gear
2014-03-04T08:53:47 < tp> but I tended to fix a lot of gear because I'm very persistent
2014-03-04T08:54:00 < GargantuaSauce> i have a cs background and thus try to debug a lot of hardware issues in software
2014-03-04T08:54:39 < tp> and I'm a electronics tech, so I try and solve a lot of software probs with hardware .. LOL
2014-03-04T08:55:40 < tp> my second micro dev platform was the old Intel STK-85 I think it was called. It featured a 8085 cpu and a hex keypad, plus 7 seg displays
2014-03-04T08:56:42 < tp> I needed to be able to write test code in ram, then map it to where eprom was expected (to test it), so what did I do ?
2014-03-04T08:58:13 < tp> I got my hands on a large multi wafer rotary switch and wired it so a turn of the switch would remap the address lines. Pos 1 was when I wanted to test the code in EPROM, pos 2 test code in ram, pos 3, burn ram code to eprom etc
2014-03-04T08:58:28 < GargantuaSauce> i was gonna say stuck some 74 logic in there
2014-03-04T08:58:32 < GargantuaSauce> that's a funnier answer
2014-03-04T08:59:32 < tp> typical tech, use a rotary switch
2014-03-04T08:59:54 < tp> youd have probably written some code to do it
2014-03-04T09:00:02 < tp> of course it was all machine code

2014-03-05T06:41:12 < Jack3k3> really dumb question probably but i am having trouble figuring out what the command is to read the current system clock value?
2014-03-05T06:47:15 < GargantuaSauce> you have to calculate it from the clock tree configuration
2014-03-05T06:47:30 < GargantuaSauce> if you're using the ST code, there's a global called SystemCoreClock that's set when that is configured
2014-03-05T06:47:55 < GargantuaSauce> extern uint32_t SystemCoreClock;
2014-03-05T06:49:03 < Jack3k3> yes i see that in the system_stm32f4xx.h

2014-03-05T07:23:34 < Jack3k3> so, i duno wtf is going on but, even though my program is working, i.e. the dma interrupt is triggering so that the rx'd values from adc1 are passed into the tx bufffer for I2S2, however, nothing that I put in the main function while loop is executing
2014-03-05T07:23:42 < Jack3k3> reallly weird

2014-03-05T07:45:12 < Jack3k3> ok so im making a little sinewave modulator, ive tested the timing code is working, so essentially there is a variable which slowly cycles thru a sinewave values (shifted/ around) but the value goes from 0 up to 1  then back  to 0, etc repeating like a sinewave
2014-03-05T07:46:30 < Jack3k3> in the dma interrupt handler, i'm taking the rx'd adc sample and multiplying it by this value to modulate the sample prior to sending it back out

2014-03-05T07:46:57 < Jack3k3> like so: tx_buffer[0] = (uint16_t)(modval*( (float)rx_buffer[0]));  is there something wrong with this?
2014-03-05T07:47:34 < GargantuaSauce> i remember having a lot of trouble casting a float to a uint
2014-03-05T07:47:56 < GargantuaSauce> use an intermediate s32 variable
2014-03-05T07:48:58 < GargantuaSauce> and you've enabled the fpu right? just making sure

2014-03-05T07:51:14 < GargantuaSauce> as far as c is concerned that's undefined behaviour i think, and i believe this implementation's choice is a hardfault
2014-03-05T07:51:25 < Jack3k3> i believe so..in system init ive got the if (_fpu_present == 1) && (__FPU_Used == 1) statements and both those defines are 1
2014-03-05T07:51:30 < Jack3k3> so i think its enabled
2014-03-05T07:53:42 < Jack3k3> ah nevermind its something else entirely, the buffer i was modifiing is actually not doing anything lol..
2014-03-05T07:55:44 < dongs> zero * stuff = zero
2014-03-05T08:01:19 < Jack3k3> theres something i dont understand, theres 2 dma's running, first is TX and  direction mem To periph (SPI2 -> txbuff) , second RX and direction periph to mem (ADC -> rxbuff).. somehow, even though i'm doing nothing but clearing the DMA flag in its interrupt handler, the adc value is passed to the i2s
2014-03-05T08:01:53 < Jack3k3> however txbuff and rxbuff are seperate variables, i.e. seperate locations in memory... how does the dma already know how to copy it if im not doing it?

2014-03-05T08:03:29 < Jack3k3> okay move then
2014-03-05T08:03:41 < dongs> its doing neither
2014-03-05T08:04:57 < Jack3k3> whaaaaaaat? I thought the whole point of the dma was to move data from mem-> periph, periph->mem, and mem->mem
2014-03-05T08:10:04 < dongs> yes
2014-03-05T08:10:12 < dongs> its moving ADC>mem
2014-03-05T08:10:16 < dongs> and some other mem>I2S
2014-03-05T08:10:24 < dongs> but its not magically copying/moving mem->someothermem
2014-03-05T08:10:26 < dongs> unless you set it up
2014-03-05T08:11:51 < Jack3k3> well theres some magic bullshit because i can specifically see the two dma channels and one points to rx_buffer and the other to tx_buffer
2014-03-05T08:12:03 < Jack3k3> and im not copying those to eachother anywhere else
2014-03-05T08:12:28 < dongs> < Jack3k3> like so: tx_buffer[0] = (uint16_t)(modval*( (float)rx_buffer[0]));  is there something wrong with this?
2014-03-05T08:12:31 < dongs> orly?
2014-03-05T08:12:35 < Jack3k3> i commented that out
2014-03-05T08:12:41 < Jack3k3> promise, there is nothing in the irq handler
2014-03-05T08:12:48 < Jack3k3> just clearing the flag

2014-03-05T08:17:16 < Jack3k3> hm mine looks same still
2014-03-05T08:19:46 < Jack3k3> is there anything magic about the rx/tx buffers being _IO , i thought thats just volatile
2014-03-05T08:19:53 < dongs> thats what it is.
2014-03-05T08:20:44 < Jack3k3> not sure i get why, it just says it forces compile to re-read a value each time it is needed rather than optimizing it off?
2014-03-05T08:21:18 < dongs> sure
2014-03-05T08:21:32 < dongs> since its dma, its modified by hardware
2014-03-05T08:21:36 < dongs> so not using cached/wahtever value
2014-03-05T08:22:11 < Jack3k3> ah, sneaky sneaky
2014-03-05T08:26:13 < Jack3k3> ok wtf i rmoved the _IO and stilllll happening
2014-03-05T08:30:12 < GargantuaSauce> are the buffer sizes the same as what you're telling the dma they are?
2014-03-05T08:30:50 < GargantuaSauce> if it's smaller it could be writing to both (and perhaps some other random memory)
2014-03-05T08:35:25 < Jack3k3> thats my guess is what happening, somehow its going over, but im telling it their size is only 1

2014-03-05T08:37:21 < dongs> hmm it would be G or E,, but there's no E
2014-03-05T08:37:43 < dongs> E only in wlcsp package

2014-03-05T08:40:29 < Jack3k3> for some reason the dma must be using more than 1 memory location i guess? im not sure why
2014-03-05T08:43:03 < dongs> "more than one"
2014-03-05T08:43:10 < dongs> why is y our d ma buffer one fucking byte
2014-03-05T08:44:07 < Jack3k3> oh fuck 1 means 1 byte = 8bits?
2014-03-05T08:44:18 < dongs> no in general
2014-03-05T08:44:21 < dongs> why is it 1
2014-03-05T08:45:01 < Jack3k3> well it was just for testing it on my first run, i thought i could just use a single buffer location and the dma would overwrite what values i didnt access in time
2014-03-05T08:45:16 < Jack3k3> like aka it would work but not very well
2014-03-05T08:48:31 < Jack3k3> wait is this because of DMA_MemoryIncEnable being set?
2014-03-05T08:48:36 < Jack3k3> i think it is
2014-03-05T08:52:09 < Jack3k3> hmm nope not it

2014-03-05T11:55:46 < dongs> use PC keyboard to type on phone.
2014-03-05T11:55:59 < dongs> phone pairs with a bt d ongle.
2014-03-05T11:57:23 < karlp> is this because pc keyboards are better than most BT ones out there?
2014-03-05T11:57:47 < dongs> karlp: this is because I have one keyboard in front of me, and if i want to type on a phone, i have to hae YET ANOTHER KEYBOARD in front of me.

2014-03-05T11:58:14 < dongs> how is that even remotely relevant
2014-03-05T11:58:18 < karlp> oh, you want a switch or something on a passthrough dongle so you can leave it connected?
2014-03-05T11:58:23 < dongs> no.
2014-03-05T11:58:35 < karlp> I thought you wanted to just plug the usb end of a regular keyboard into a dongle to let it pair with your phone
2014-03-05T11:58:38 < dongs> nope.
2014-03-05T11:58:43 < dongs> thats dumb, then i cant type on pc.
2014-03-05T11:58:56 < dongs> I wanna press some key combo and switch keyboard between pc/phone.
2014-03-05T11:58:58 < dongs> and keep typign on it.
2014-03-05T11:59:17 < dongs> the innovation = BT d ongle that phone pairs with that PC controls as a 'virtual keyboard'
2014-03-05T12:00:05 < karlp> that sounds innovation worthy :)
2014-03-05T12:01:00 < dongs> it would definitely make MY life a lot easier.

2014-03-05T13:21:45 < Cyric> hey guys. how can i generate LOW battery signal on STM? does it have some cool features that does this for me?
2014-03-05T13:22:13 < Cyric> basically my circuit run from battery and i would like to know when the battery is low...
2014-03-05T13:23:04 < Laurenceb> doesnt F3 have such a feature?
2014-03-05T13:24:01 < Cyric> i am on L152
2014-03-05T13:26:26 < Thorn> Cyric: define "battery is low"
2014-03-05T13:26:58 < Cyric> when i need to recharge it :)
2014-03-05T13:27:02 < Thorn> e.g. a Li-ion will be depleted at a much higher voltage than the minimum for most stm32 chips
2014-03-05T13:27:15 < Cyric> i have a ldo
2014-03-05T13:27:25 < Thorn> you basically need to measure voltage with an ADC
2014-03-05T13:28:09 < karlp> there's app notes from ST for doing this iirc
2014-03-05T13:28:15 < Cyric> so basically i do not want that my circuits die without telling me anything...
2014-03-05T13:28:37 < Cyric> cool let me check
2014-03-05T13:28:42 < Thorn> what kind of battery are you using?

2014-03-05T13:30:55 < Cyric> standard 3.6 V
2014-03-05T13:31:19 < Fleck> have used avr a lot...
2014-03-05T13:31:27 < Cyric> lipo batteries
2014-03-05T13:31:38 < Thorn> lipo is 3.7 iirc
2014-03-05T13:31:47 < Fleck> add diode :D
2014-03-05T13:31:56 < gnomad> lipo is anywhere from 3.0 to 4.3
2014-03-05T13:32:00 < Thorn> check the battery datasheet for minimum recommended discharge voltage
2014-03-05T13:32:22 < RaYmAn> Fleck: the discovery boards seem obvious.  Or the new Nucleo (arduino compatible headers)
2014-03-05T13:32:54 < Fleck> RaYmAn: what I need for Discovery board to programm it?
2014-03-05T13:32:56 < Thorn> Fleck: see http://www.st.com/web/en/catalog/tools/FM116/SC959/SS1532/LN1848 for discovery boards
2014-03-05T13:33:04 < Fleck> like AVRISP for atmel chips...
2014-03-05T13:33:24 < RaYmAn> Fleck: nothing. It includes a programmer
2014-03-05T13:33:24 < karlp> nothing.
2014-03-05T13:33:46 < gnomad> the discovery boards come with a programmer AND DEBUGGER built in.

2014-03-05T13:34:05 < gnomad> the name for that component part is "ST-Link V2"
2014-03-05T13:34:28 < qyx_> Fleck: order from normal stores :S
2014-03-05T13:34:33 < Fleck> ;p
2014-03-05T13:34:41 < gnomad> At $10 - $15 for a programmer and a target chip, the Discovery boards are a steal.
2014-03-05T13:34:43 < qyx_> and you don't need 429
2014-03-05T13:34:47 < qyx_> if you are a beginner
2014-03-05T13:34:55 < Fleck> qyx_: what's normal?
2014-03-05T13:34:58 < qyx_> there are $10 discovery's

2014-03-05T13:36:21 < Cyric> this is the F1 discovery... main stream of STM32
2014-03-05T13:36:35 < Fleck> also - how about linux and IDE ?
2014-03-05T13:37:16 < gnomad> gcc compiler and whatever else you want
2014-03-05T13:37:41 < gnomad> for me, that's emacs+make.  Other people use Eclipse.
2014-03-05T13:37:54 < Cyric> http://www.digikey.com/product-search/en?v=497&mpart=NUCLEO-F103RB
2014-03-05T13:38:20 < Cyric> this look cooler and arduino pin compatible but is a little more expensive
2014-03-05T13:38:23 < gnomad> the nucleo boards are nice because they all have backchannel serial through the USB port
2014-03-05T13:38:59 < gnomad> nucleo boards a re *cheaper* than most cheap arduino clones...
2014-03-05T13:39:02 < Cyric> I use COCOOX is free and there are a lot of nice features
2014-03-05T13:39:10 < Cyric> as IDE

2014-03-05T13:40:32 < dongs> qyx_: oh, that was just assembly (but will likely be lower since only a few compoentns). pcb depends how many m^2 panels that will end up being
2014-03-05T13:41:24 < qyx_> dongs: /o\
2014-03-05T13:41:41 < dongs> can find out tomrorow. everyone is partying
2014-03-05T13:41:54 < qyx_> 6.5m^2 + milling + borders
2014-03-05T13:42:12 < qyx_> also if 0.2mm is possible
2014-03-05T13:42:16 < Fleck> Cyric: System requirements: Windows XP SP3/Windows Vista/Windows 7
2014-03-05T13:42:27 < qyx_> i got ~4000e from local fab without assembly :S
2014-03-05T13:42:27 < dongs> 0.2 thickness?
2014-03-05T13:42:40 < dongs> qyx_: haha, it'll be way less than that
2014-03-05T13:42:46 < dongs> i think 0.3 is smalelst standard
2014-03-05T13:43:26 < qyx_> then 0.3, it would end epoxided on iron plate
2014-03-05T13:43:39 < qyx_> or laminated or whatever
2014-03-05T13:43:56 < qyx_> so doesnt need to be mechanically strong
2014-03-05T13:44:01 < Cyric> fleck sorry i use it on winzoz but there are source files there
2014-03-05T13:45:33 < Cyric> i though was for linux too but it does not seems so..
2014-03-05T13:45:33 < Fleck> qyx_: Why I don't need 429? :D I like feature rich and fast MCUs! :D Also mega2560 was my first board :D
2014-03-05T13:46:17 < Cyric> because if you are new, than you will struggle to make the led blink :D

2014-03-05T13:59:53 < Cyric> BTW, coming back at the battery measurement level, i will need to use and initialize a ADC and read the voltage level and compare with the discharge voltage on the battery datasheet?
2014-03-05T14:00:17 < Cyric> this will make the system consume much more!
2014-03-05T14:00:29 < dongs> i thought theres some pin you can abuse to measure
2014-03-05T14:00:47 < dongs> in other news
2014-03-05T14:00:51 < dongs> dicktrace sucks on hidpi
2014-03-05T14:00:53 < dongs> its zoomed in.
2014-03-05T14:00:54 < dongs> fuck.
2014-03-05T14:01:08 < karlp> Cyric: yes, measuring things takes power....
2014-03-05T14:01:16 < Cyric> i know
2014-03-05T14:01:21 < karlp> but you don't need to watch it at 32Mhz...
2014-03-05T14:01:31 < dongs> watch it at 72mhz
2014-03-05T14:01:52 < karlp> gotta see the 5th harmonic of the battery drain...
2014-03-05T14:01:58 < Cyric> but for running ADC do i need external crystals? or the MSI will be enought?
2014-03-05T14:02:05 < karlp> totally enough
2014-03-05T14:02:18 < karlp> we're shipping L151 products with no cryustals on board and all they do is run the ADC
2014-03-05T14:02:33 < Cyric> ok cool
2014-03-05T14:02:49 < karlp> what would have made you think you couldn't?
2014-03-05T14:03:01 < Cyric> at least i can save 2bucks
2014-03-05T14:03:09 < karlp> also, if you read your L1 manual again, you'll see that the l1 adc's are _always_ on HSI, no matter what anyway...
2014-03-05T14:03:15 < Cyric> well i do not know... accuracy?
2014-03-05T14:03:34 < dongs> its not like adc needs precise clock. ?/
2014-03-05T14:03:37 < karlp> accuracy of what? crystals are for timing, not for adc
2014-03-05T14:03:53 < Cyric> ok sorry :S
2014-03-05T14:05:09 < Cyric> anyway i will check the datasheet to see if i find a LOWBAT pin... if not i will implement this function by using ADC
2014-03-05T14:05:25 < dongs> waht i meant is
2014-03-05T14:05:29 < dongs> theres someshit to read vbat
2014-03-05T14:05:31 < dongs> using adc
2014-03-05T14:05:33 < dongs> vbat pin

2014-03-05T14:05:40 < karlp> no vbat on L1
2014-03-05T14:05:44 < dongs> i rememer some discussion about this in here
2014-03-05T14:05:45 < dongs> ah ok then
2014-03-05T14:05:48 < dongs> so that answers that
2014-03-05T14:06:03 < karlp> if you're tricksy you can use the vrefint to see what your vcc is at, and not need any external parts though.
2014-03-05T14:07:53 < Fleck> Cyric: how about F3 or F4 Discovery ?
2014-03-05T14:09:49 < Cyric> they are different families of STM32
2014-03-05T14:10:13 < Cyric> basically there are F1 wich is the mainstream
2014-03-05T14:10:24 < Cyric> L1 low power
2014-03-05T14:11:27 < Cyric> F3 and F4 use ARM Cortex-M4F
2014-03-05T14:12:00 < Cyric> and they include more feautures such as Floating point
2014-03-05T14:12:32 < Cyric> DSP etch
2014-03-05T14:12:36 < Cyric> etc
2014-03-05T14:14:14 < Cyric> if you want just to start using STM32 for reading sensors, serial communication, SPI communicaiton etch than the F1 discovery is more than enought
2014-03-05T14:14:39 < Cyric> http://en.wikipedia.org/wiki/STM32#STM32_F3
2014-03-05T14:14:56 < Cyric> here there are the different STM families

2014-03-05T14:28:46 < Cyric> fleck do you need screen onboard?
2014-03-05T14:29:07 < Fleck> no
2014-03-05T14:29:17 < karlp> Cyric: we tend to avoid recommending the f100 discovery, as it only has the old stlink interface on it,
2014-03-05T14:29:31 < karlp> if you want an f1 board, the new f1 nucleo is a better choice
2014-03-05T14:29:34 < Fleck> karlp: F3?
2014-03-05T14:30:51 < dongs> ya nucleo is a good deal
2014-03-05T14:30:58 < dongs> i got 2 F401 versions
2014-03-05T14:31:03 < dongs> so i can create amazing arduino comaptible shields
2014-03-05T14:31:21 < dongs> or suck dick, whichever is more interesting
2014-03-05T14:32:00 < Fleck> you suck dicks? Not cool...
2014-03-05T14:32:06 < karlp> my colleague went to embedded world and didn't bring me back any freebies
2014-03-05T14:32:18 < karlp> didn't even tell any of us he wsa going either!
2014-03-05T14:32:30 < Cyric> i have some nucleos too... i got from the embedded world conference last week!
2014-03-05T14:33:02 < Cyric> I have also the new L0 :)
2014-03-05T14:33:08 < dongs> ^ lol
2014-03-05T14:36:12 < PaulFertser> Did dongs just implied he'd be rather sucking dick than creating an arduino compatible shields?
2014-03-05T14:36:24 < PaulFertser> As I know how much he hates arduino shields.
2014-03-05T14:36:31 < karlp> no, just that he'd do either, depending on which one he found more interesting
2014-03-05T14:36:41 < Fleck> ;p
2014-03-05T14:38:05 < PaulFertser> But he is interested in laughing at arduino products, not making. Hence my conclusion.

2014-03-05T17:36:13 < Steffanx> Allowed to tell what kind of device this is Thorn?
2014-03-05T17:37:32 < Thorn> basically a fancy thermostat with a CAN bus etc.
2014-03-05T17:39:43 < dongs> does it connect with canbus to different rooms?
2014-03-05T17:39:44 < dongs> or wat
2014-03-05T17:40:34 < Thorn> it controls several ovens, there's a controller per oven and a central one
2014-03-05T17:42:10 < Fleck> ok guys, I ordered F4 Discovery!
2014-03-05T17:42:46 < Thorn> thermal inertia varies per oven, total current is limited etc.
2014-03-05T17:43:00 < Thorn> but I wouldn't mind a more interesting project lol.
2014-03-05T17:43:48 < Thorn> maybe I should seriously consider that usb analyzer project after all
2014-03-05T17:44:15 < dongs> so how do you connect per oven to central?
2014-03-05T17:44:16 < dongs> canbus?
2014-03-05T17:44:29 < Thorn> yes, CAN
2014-03-05T17:44:38 < dongs> got a bunch of drivers in main thing? or do you just hook it up in star off one driver
2014-03-05T17:45:31 < Thorn> just a single bus, one driver per device (hd a hard time explaining to the customer how it works even though he is a EE lol)
2014-03-05T17:46:22 < dongs> glad to see that works
2014-03-05T17:46:30 < dongs> im doing something very similar
2014-03-05T17:47:26 < Robint91> CAN IS AWESOME
2014-03-05T17:47:26 < Thorn> (there are no stubs on the bus)
2014-03-05T17:49:40 < Thorn> I find CAN much easier to use than RS-485
2014-03-05T17:50:01 < Thorn> (as long as you can live with 8-byte messages)
2014-03-05T17:51:00 < Robint91> Thorn, I implemented a sort of fragmentation to send more as 8 bytes
2014-03-05T17:51:11 < Robint91> I had a bootloader that worked over CAN
2014-03-05T17:51:56 < Thorn> you can make a TCP-like layer but it's not very pretty IMO (although it can still be better than rs-485)
2014-03-05T17:52:27 < Robint91> Thorn, also using extended frames can make life easier

2014-03-05T17:57:15 < karlp> what's "easier" with can thorn? just that addressing is built in?
2014-03-05T17:57:54 < Thorn> you don't need request/response and polling, CRC is built in, message filters etc.
2014-03-05T17:58:06 < Thorn> and of course retransmit
2014-03-05T17:59:50 < Robint91> auto ack
2014-03-05T18:00:31 < dongs> Thorn: no stubs? what topology? star?
2014-03-05T18:00:42 < Thorn> consider a peripheral device with a button (like in an access control system). CAN: button pressed, send message. RS-485: remember button press, reply "I had a button press" when asked next time (could be a few seconds)
2014-03-05T18:00:59 < karlp> yeah, that's a nice thing about can,
2014-03-05T18:01:21 < karlp> are the restransmits on address/priority conflict built in?
2014-03-05T18:01:36 < karlp> I thought if you tried to send and someone else was higher yourse just got thrown out
2014-03-05T18:01:54 < karlp> then again, no-one uses rs485 by itself,
2014-03-05T18:02:16 < Thorn> the lower priority message is retransmitted automatically iirc after a collision
2014-03-05T18:02:23 < karlp> can just has more "batteries included" than rs485 does
2014-03-05T18:04:11 < Thorn> dongs: no, not a star, a multipoint bus (1->2, 2->3, 3->4 etc.)

2014-03-05T19:38:03 < aadamson> anyone care to answer an *easy* lectronics quesiton? :)
2014-03-05T19:39:05 < aadamson> want to use a 2n7002 to switch a 1.8v source to an input on another device with a processor pin that has a higher than 1.8 voltage... so basically, got G, D, S and vdd(1.8) input pin, output pin, which goes where?
2014-03-05T19:39:46 < aadamson> I need to switch a 1.8v logic high/low with a processor pin that is higher than the input can tolerate, but the input has it's own vdd that is 1.8

2014-03-05T19:46:55 < Bird|otherbox> aadamson: will a 2n7002 even turn on with 1.8V Vgs?
2014-03-05T19:47:20 < Bird|otherbox> but for any FET doing this: source to ground, gate to input, drain to output
2014-03-05T19:47:27 < englishman> Sounds like job for resistor voltage divider maybe
2014-03-05T19:47:42 < Bird|otherbox> oh....I see, you have it backwards
2014-03-05T19:47:57 < Bird|otherbox> but yeah, a voltage divider is the simple if seemingly slightly hacky way of doing this
2014-03-05T19:48:06 < Bird|otherbox> you'd want the FET if you were going the *other* way
2014-03-05T19:48:49 < englishman> Or CMOS buffer
2014-03-05T19:49:55 < aadamson> I can't use a VD and the reason is that I want the board to be able to support a wide span of voltages... so for example.  if I power the board with 2.0v, the VD would create a 1.0v and that is right at the threshold for the input.
2014-03-05T19:50:32 < aadamson> so I want my cake and eat it too... if I use a fet and the VDD for the 1.8 part as the logic level, I can run it all at all voltage (obviously needing to make sure I provide that part with 1.8v only)
2014-03-05T19:53:24 < aadamson> Bird|otherbox, thanks, but could I get you to clarify?  you gave pins assignments for ground, I looking for it for 1.8v :)
2014-03-05T19:53:26 < zyp> not asleep, just away from a computer all day
2014-03-05T19:53:41 < Bird|otherbox> aadamson: aaaaah!
2014-03-05T19:54:10 < Bird|otherbox> aadamson: source and drain go to the input/output lines, and the gate is pulled up to the lower of the two voltages, minus a bit of a drop
2014-03-05T19:54:26 < Bird|otherbox> or it might be the higher
2014-03-05T19:54:42 < aadamson> hehe... what I thought was an easy question :)... lol
2014-03-05T19:54:56 < aadamson> let me try this with a little help...
2014-03-05T19:55:46 < Bird|otherbox> it is the higher, sorry
2014-03-05T19:55:48 < aadamson> I have vdd that is 1.8v and I want to use it for a logic high to an input on a controller that is on the same vdd.  I want to switch that 1.8 on and off (create high and low) with a different processor that is on a different voltage :)
2014-03-05T19:55:50 < Bird|otherbox> usually through a resistor
2014-03-05T19:56:13 < aadamson> and I want to use a 2n7002 to do the above
2014-03-05T19:56:14 < Bird|otherbox> aaah
2014-03-05T19:56:28 < aadamson> (with a pullup because the input only has a 500k internal pull up)
2014-03-05T19:56:35 < Bird|otherbox> aadamson: does it matter if the logic of the output from the different processor is inverted?
2014-03-05T19:57:01 < aadamson> no really, I can account for that in software and there is no frequency issue it's just an enable/disable pin
2014-03-05T19:58:00 < aadamson> ah I say that... so just as you treat most enables as active low, I think conceptually it can be inverted no problem
2014-03-05T19:59:07 < aadamson> no really = not really above :(
2014-03-05T19:59:40 < aadamson> gotta run, but fire away, I'll catch it when I return
2014-03-05T20:01:37 < Bird|otherbox> aadamson: what you can do then is wire it as an inverter
2014-03-05T20:01:50 < Bird|otherbox> which is what I originally said to do :)
2014-03-05T20:05:50 < SlaveToTheSauce_> why not use an OD output on a 5v tolerant pin?
2014-03-05T20:06:36 < Bird|otherbox> SlaveToTheSauce_: because 1.8V is Vdd (destination)
2014-03-05T20:06:48 < Bird|otherbox> and the processor pin has that diode to Vdd :p
2014-03-05T20:07:33 < SlaveToTheSauce_> oh i interpreted the above as the opposite
2014-03-05T20:08:20 < SlaveToTheSauce_> ...i don't think that changes my answer. OD output and pull up to destination's Vdd
2014-03-05T20:08:48 < Bird|otherbox> SlaveToTheSauce_: yeah
2014-03-05T20:09:18 < Bird|otherbox> although if he doesn't have enough voltage to turn on a FET at the output pin
2014-03-05T20:09:38 < Bird|otherbox> a series Schottky can be used as a way to make a pseudo-open-drain ouput from a totem-pole one ;)
2014-03-05T20:09:54 < SlaveToTheSauce_> no need for an external fet, assuming we're talking an stm32 mcu there's the open drain output mode
2014-03-05T20:10:29 < SlaveToTheSauce_> not that there aren't fets that turn on at that voltage
2014-03-05T20:14:45 < englishman> Maybe 1.8V zener :D

2014-03-06T01:57:42 < dongs> 5x5 qfn i think
2014-03-06T01:57:51 < karlp> their newest kl03z is 1.9x2.2mm wlcsp or something nuts
2014-03-06T01:58:07 < ds2> but the stm32's don't have that stable of an RC oscillator, right?
2014-03-06T01:58:14 < dongs> uh
2014-03-06T01:58:16 < dongs> define "stable"
2014-03-06T01:58:18 < karlp> depends what you mean by stable
2014-03-06T01:58:20 < dongs> its better htan the one in atmel avr
2014-03-06T01:58:23 < ds2> 1.2% or better
2014-03-06T01:58:33 < dongs> the new f07 or whatever series does
2014-03-06T01:58:34 < dongs> enough for usb

2014-03-06T01:59:12 < dongs> sounds like you want a crystal then?
2014-03-06T01:59:30 < ds2> don't really have room for xtal
2014-03-06T01:59:31 < karlp> must be fast sensors :)
2014-03-06T01:59:33 < dongs> you can get tiny 1.6x1.2mm 12-16mhz crystals
2014-03-06T01:59:43 < ds2> that and 2 caps
2014-03-06T01:59:49 < ds2> that's almost hte size of the processor!

2014-03-06T02:01:28 < dongs> thats gonna take up a lot of space

2014-03-06T04:26:10 < dongs> This driver is available for advanced users only! The Molex connector that is used to connect to the LG display is insanely delicate and breaks very very very easily if you are not very careful! If you order this driver board and break the connector, it may no longer work and we cannot repair it. If you break it you may have to buy another driver. We do not offer any returns, refunds or replacements! Do not purchase if you are not comfortable with this risk!
2014-03-06T04:26:16 < dongs> haha
2014-03-06T04:26:35 < dongs> for 80 bucks, i don't really see how they can't afford to send an extra one with each purchase
2014-03-06T04:28:06 < gnomad> Does "advanced" mean "capable of using something other than arduino"?
2014-03-06T04:28:14 < dongs> no
2014-03-06T04:28:27 < dongs> advanced arduino = C on attiny
2014-03-06T04:28:41 < gnomad> I mean, how delicate are these things really.
2014-03-06T04:28:55 < dongs> pretty bad actually
2014-03-06T04:29:01 < dongs> out of ~200 i made i broke like 5
2014-03-06T04:29:18 < dongs> the black flap just  snaps off edges
2014-03-06T04:29:22 < dongs> cable still works if you tape it
2014-03-06T04:29:34 < dongs> just loses the pressure that the tab provides
2014-03-06T04:29:38 < gnomad> wow
2014-03-06T04:29:50 < gnomad> did you tend to break more at the beginning of the production run?
2014-03-06T04:30:09 < gnomad> or were they still breaking after you had a good bit of experience with them?
2014-03-06T04:30:21 < dongs> no, actually at first it was ok, then there was a few unlucky ones, then have been OK so far
2014-03-06T04:30:30 < dongs> could have bene connector quality too.
2014-03-06T04:30:35 < dongs> tho I've been using same source
2014-03-06T04:30:42 < dongs> molex can't really be that bad
2014-03-06T04:30:52 < dongs> but really its one-time use, you snap it in place and dont touch it again.
2014-03-06T04:31:30 < gnomad> given that the tablets they are designed for, I suppose that isn't really an issue.
2014-03-06T04:31:35 < dongs> right
2014-03-06T04:37:02 < Bird|otherbox> yeah, those flex connectors are rather aggravating re: lack of durability
2014-03-06T04:37:02 < Bird|otherbox> is the tab captive, even?
2014-03-06T04:55:40 < dongs> no, who cares about that shit

2014-03-06T05:13:33 < dongs> oh sorry.
2014-03-06T05:13:36 < dongs> misunderstood the question
2014-03-06T05:13:47 < dongs> tab is used to pressure 2 parts of the connector together
2014-03-06T05:13:57 < dongs> so teh metal contactspress the fpc
2014-03-06T05:14:11 < dongs> if it breaks off, connector is kinda loose but still makes OK-ish contact
2014-03-06T05:14:21 < dongs> englishman: broke his off and just taped it and it still worked
2014-03-06T05:16:30 < Bird|otherbox> yeah
2014-03-06T05:16:33 < Bird|otherbox> I know what it does
2014-03-06T05:16:57 < Bird|otherbox> but on some connectors, it's captive to the connector (i.e. it's hinged)
2014-03-06T05:17:03 < Bird|otherbox> on others, it comes out altogether
2014-03-06T05:17:10 < Bird|otherbox> (and then becomes painful to get back in again)
2014-03-06T05:18:31 < aadamson> so if anyone is curious... it's nfet, mcu pin goes to gate (obviously), input pin goes to drain, source to ground, input pin gets a 10k pull up to 1.8v and poof... an active low on the mcu pin gives and active high on the input and all is good in the land of making logic level without a voltage divider :)  Thanks to all I'm sure someone said this already and I was just thick skinned and had to figure it out myself.... (and simulate
2014-03-06T05:18:31 < aadamson>  it in QUCS :)..)
2014-03-06T05:19:07 < aadamson> should say making level adjusted logic level :)

2014-03-06T05:22:35 < dongs> Bird|otherbox: it is hinged, and the hinges break easily
2014-03-06T05:23:30 < dongs> they're on corners.
2014-03-06T05:23:33 < dongs> and its a pretty thin bar.
2014-03-06T05:23:46 < dongs> the pin that holds it in place is like 0.3mm  thick
2014-03-06T05:26:12 < Bird|otherbox> dongs: *nods*
2014-03-06T05:26:13 < dongs> aadamson: sounds legit
2014-03-06T05:26:37 < dongs> next question why you bothering wiht 1.8V I/O
2014-03-06T05:26:59 < dongs> you can't use anything below 5V in arduino projects
2014-03-06T05:27:00 < Bird|otherbox> dongs: because the thing he's driving can't accept higher voltages?
2014-03-06T05:27:19 < dongs> thats illegal in hobby MAKE:r projects
2014-03-06T05:27:24 < dongs> use a shield instead.
2014-03-06T05:28:25 < Bird|otherbox> dongs: you need to learn that trolling *all* the time doesn't work.
2014-03-06T05:28:45 < Bird|otherbox> and that some trolls wear out, or just don't apply :p
2014-03-06T05:29:17 < dongs> arduino shields talk is hardly trolling
2014-03-06T05:29:33 < Bird|otherbox> also: when will ST backport the F0 IWDT to the rest of the STM32Fx parts?
2014-03-06T05:29:55 < dongs> is it good or soemthing
2014-03-06T05:30:04 < Bird|otherbox> the F0's IWDT supports windowed operation
2014-03-06T05:30:35 < Bird|otherbox> which is good, because the WWDT won't save you from a haywire main clock
2014-03-06T05:30:59 < dongs> oh
2014-03-06T05:31:07 < dongs> but
2014-03-06T05:31:12 < dongs> doesnt Fx have clock security system
2014-03-06T05:31:17 < dongs> where it'll switch to HSI if HSE fails?
2014-03-06T05:31:19 < dongs> or was that only stm8
2014-03-06T05:31:22 < Bird|otherbox> dongs: if HSE *fails*
2014-03-06T05:31:26 < dongs> yeah?
2014-03-06T05:31:34 < Bird|otherbox> what if noise causes HSE to jump overtones, or onto a spurious?
2014-03-06T05:31:35 < dongs> as opposed to wat
2014-03-06T05:31:44 < dongs> oic
2014-03-06T05:31:46 < Bird|otherbox> so your timing's hosed
2014-03-06T05:32:03 < dongs> not needed in arduino projectss
2014-03-06T05:32:06 < dongs> none of them are flying to hte moon
2014-03-06T05:32:12 < dongs> where cosmic rays will bump your bits
2014-03-06T05:32:13 < Bird|otherbox> but neither the clock security system nor the STM32 WWDT will catch you
2014-03-06T05:32:13 < dongs> in sram
2014-03-06T05:33:52 < Bird|otherbox> and I'm talking ordinary EMI here, no need for cosmic rays in order to send a crystal off onto the wrong frequency.
2014-03-06T05:34:34 < dongs> http://scenesat.com/track/777 good
2014-03-06T05:34:37 < Bird|otherbox> (although I wouldn't be surprised if it would fail in that way *at startup*, not so much once its nice and going)
2014-03-06T05:38:27 < aadamson> it's an STM32L1 at 1.65-3.3v (just want a common design that can support the full range even tho it will be 2.0v out the gate), and the PLL I'm talking too is only 1.8v tolerant on the enable pin
2014-03-06T05:38:56 < aadamson> I couldn't do it with a VD because at 2.0v it would only give me 1.0v which is the threshold on that enable pin
2014-03-06T05:39:24 < aadamson> sheesh I haven't mucked with arduino in some time... been all STM for me for a while...
2014-03-06T05:39:29 < aadamson> but not all RC related
2014-03-06T05:39:42 < dongs> could always go with NC7SZ125 or something similar too
2014-03-06T05:39:46 < dongs> probly just as cheap as fet tho.
2014-03-06T05:40:05 < dongs> less parts?

2014-03-06T05:41:17 < aadamson> opposite end of the stick from the processor
2014-03-06T05:41:21 < aadamson> already have that part working

2014-03-06T05:42:28 < aadamson> doing FM via VCXO on that one, replaced the VCXO with a PLL just for kicks...
2014-03-06T05:42:44 < dongs> nice wirewound coils
2014-03-06T05:42:53 < aadamson> yeah,
2014-03-06T05:42:58 < dongs> and some chip ones.
2014-03-06T05:43:01 < aadamson> better efficiency
2014-03-06T05:43:14 < dongs> are those caps like 0.5pF
2014-03-06T05:43:15 < aadamson> all the coils should be wirewound on that the other are caps
2014-03-06T05:43:24 < englishman> lowest is like 1.8pf iirc
2014-03-06T05:43:25 < englishman> <aadamson> doing FM via VCXO on that one
2014-03-06T05:43:25 < dongs> L9 is  chip coil
2014-03-06T05:43:27 < englishman> that is a cool hack
2014-03-06T05:43:35 < englishman> using si4463 as freq multiplier
2014-03-06T05:43:50 < aadamson> no, but all little PF ones to do the low pass filter
2014-03-06T05:44:16 < aadamson> ok and I figured out how to do 16 freq mfsk on ssb too via a similar approach.
2014-03-06T05:44:29 < aadamson> still need to prove that, but in the testing that I did it will work
2014-03-06T05:44:44 < aadamson> just pull the vcxo to a differnt frequency :)
2014-03-06T05:44:57 < aadamson> have much finer control there than I do with the steps in the SI part

2014-03-06T05:47:13 < Bird|otherbox> those sorts of functions *are* handy
2014-03-06T05:47:31 < aadamson> Hey, that looks like a kinda cool part... need to look more at it!
2014-03-06T05:48:07 < dongs> they were liek 6 cents when I bought them
2014-03-06T05:48:13 < dongs> used to buffer spdif output into rca
2014-03-06T05:48:37 < dongs> even in singles not bad i guess.
2014-03-06T05:49:04 < aadamson> well, I need to remember that one, that could work too I think,
2014-03-06T05:49:06 < dongs> comparable to fet, but non-inverting so you dont have to dick wiht invreting logic
2014-03-06T05:49:25 < aadamson> I actually need the inversion.. the enable on the PLL is active high
2014-03-06T05:49:33 < dongs> and i think there's a non-3state version as well
2014-03-06T05:49:36 < aadamson> and I need the pull up too as the enable is only a 500k internal
2014-03-06T05:49:45 < englishman> $0.051
2014-03-06T05:49:49 < englishman> how is that more than 6 cents?
2014-03-06T05:49:56 < dongs> hm?
2014-03-06T05:49:56 < englishman> oh 1000
2014-03-06T05:50:44 < englishman> the 1st and 4th in the list are much cheaper than the others
2014-03-06T05:51:50 < dongs> common packages
2014-03-06T05:51:58 < dongs> sc70 is 1 size under SOT23 right?
2014-03-06T05:52:05 < dongs> i bought some trash in that by mistake
2014-03-06T05:52:06 < englishman> looks like it
2014-03-06T05:52:08 < dongs> raged endlessly
2014-03-06T05:52:29 < dongs> it doesnt quite fit into sot23 pinout
2014-03-06T05:52:31 < englishman> still .65mm pitch
2014-03-06T05:52:34 < dongs> the pitch is too small
2014-03-06T05:52:34 < englishman> hehe
2014-03-06T05:52:35 < dongs> no its not
2014-03-06T05:52:41 < dongs> it will short the 3 pins on sot23 pads
2014-03-06T05:53:51 < englishman> do you know of a similar part but with higher voltage
2014-03-06T05:54:00 < englishman> like that could be used as voltage protection
2014-03-06T05:54:02 < englishman> 25v or so
2014-03-06T05:54:18 < dongs> no but theres something eles that does that
2014-03-06T05:54:24 < englishman> a lot of the buffers i have seen have the input voltage maximum relative to vcc
2014-03-06T05:54:36 < englishman> what's that?
2014-03-06T05:54:44 < dongs> NCP349MNAETBGOS
2014-03-06T05:54:51 < dongs> not sure what y oure' trying to achieve, but i think its that.

2014-03-06T05:55:51 < englishman> yep cool
2014-03-06T05:56:29 < Bird|otherbox> dongs: I think SC70 is SOT323 or smt hlike that
2014-03-06T05:56:34 < englishman> hm really for supply tho not for logic
2014-03-06T05:56:37 < aadamson> ok, we need a new BOT, one that just monitors dongs and his urls posted for *good* stuff in circuits, components, etc.... and a way to catalog and search them :)
2014-03-06T05:56:43 < dongs> englishman: right, of course for supply.
2014-03-06T05:56:58 < dongs> i cant imagine why you'd need this kinda shit for logic.
2014-03-06T05:57:04 < dongs> stupid users?
2014-03-06T05:57:07 < englishman> for interfacing with unknown shits
2014-03-06T05:57:11 < englishman> for example
2014-03-06T05:57:15 < englishman> tardanis outputs ppm at Vbat
2014-03-06T05:57:22 < dongs> are u srs
2014-03-06T05:57:25 < englishman> srs
2014-03-06T05:57:28 < dongs> 12V?
2014-03-06T05:57:32 < englishman> well Vbat
2014-03-06T05:57:43 < Bird|otherbox> ...sounds like a PITA
2014-03-06T05:57:49 < dongs> yes, but vbat is 12V?
2014-03-06T05:57:55 < englishman> if your Vbat is 12V yes
2014-03-06T05:57:59 < Bird|otherbox> considering how that IC behaves though
2014-03-06T05:58:11 < englishman> with NiMH it's like 6V
2014-03-06T05:58:17 < dongs> thats so fucked up
2014-03-06T05:58:19 < aadamson> I htink it's 9v actually
2014-03-06T05:58:21 < dongs> do tehy know about this?
2014-03-06T05:58:25 < dongs> )or care)
2014-03-06T05:58:26 < englishman> probably
2014-03-06T05:58:37 < englishman> i use 3s life so it's like 9.5v
2014-03-06T05:58:39 < Bird|otherbox> I'd say that a 3-pin LDO might actually be the best bet here, either that or an optocoupler
2014-03-06T05:58:52 < englishman> opto might be good idea
2014-03-06T05:59:08 < dongs> 3 pin ldo? doens't have some startup delay etc
2014-03-06T05:59:41 < aadamson> 6 cell nimh batter btw
2014-03-06T05:59:42 < aadamson> battery
2014-03-06T06:00:05 < aadamson> thats what it comes with
2014-03-06T06:01:39 < dongs> i cant afford such shit
2014-03-06T06:01:44 < dongs> i'm using pro 9xr
2014-03-06T06:02:32 < Bird|otherbox> or actually, come to think of it, just use a comparator :P
2014-03-06T06:02:38 < Bird|otherbox> why'd I think of a LDO? lol
2014-03-06T06:03:06 < dongs> ohh, comparator
2014-03-06T06:03:10 < dongs> awesome analol'g protip
2014-03-06T06:04:49 < dongs> LM211 like a pro
2014-03-06T06:04:58 < dongs> then you can connect 6S to that shit and laugh at frsky

2014-03-06T06:25:57 < aadamson> most of the STEP's that I've downloaded from there were drop ins, a few I have to adjust not in scale, just where they need to go and if they need a twist or turn.
2014-03-06T06:26:17 < aadamson> englishman, is always giving me grief about spending the time to 3d a board... but oh well ;)
2014-03-06T06:26:25 < englishman> nah
2014-03-06T06:26:27 < englishman> it's cool
2014-03-06T06:26:46 < aadamson> i can give you the numbers on that part if you want them?
2014-03-06T06:27:07 < dongs> http://www.ebay.com/itm/141161961866 what. note3 has usb3.0?
2014-03-06T06:27:47 < dongs> holy shit it does
2014-03-06T06:27:48 < aadamson> to align that it's 1.33mm Y shift, 2.24mm z shift, and an x angle of 90 and a y angle of 180 and that it

2014-03-06T07:00:08 < gnomad> regular == full size or regular == mini-usb?
2014-03-06T07:00:51 < dongs> no
2014-03-06T07:00:52 < dongs> microusb3.0
2014-03-06T07:00:55 < dongs> which is wide and dumb
2014-03-06T07:01:33 < GargantuaSauce> at least it's standard usb and not the dumb samsung-connector
2014-03-06T07:01:41 < gnomad> heh... yeah... I've developed an intense dislike for all things cell phone and tablet in recent years
2014-03-06T07:01:43 < dongs> lucky i never owned any samsung shit
2014-03-06T07:01:44 < GargantuaSauce> i have a worktablet with one of those and it's annoying as hell
2014-03-06T07:02:05 < GargantuaSauce> i just got a galaxy note 10.1 2014 today though and it is pretty decent
2014-03-06T07:03:05 < tp> gnomad:  I have a 2014 Nexus7 tablet, and it is damn good, Ive dumped my kindle and hardly use my phone any more
2014-03-06T07:03:52 < tp> GargantuaSauce:  I also have a wireless charger pad (damn inefficient) but it beats muching with the small USB connector
2014-03-06T07:04:16 < GargantuaSauce> i certainly prefer micro-usb to dumb wide ipad-connector-wannabe
2014-03-06T07:04:17 < tp> dongs:  agree with you, I don't like Samsung gear much
2014-03-06T07:04:26 < englishman> 2014 n7?
2014-03-06T07:04:32 < dongs> i cant say like or not, since i never owneds any :)
2014-03-06T07:04:42 < dongs> i think he means 2013.
2014-03-06T07:04:47 < dongs> its ok, my spawn uses it for alarm.
2014-03-06T07:04:50 < dongs> useless for anything else
2014-03-06T07:04:51 < tp> englishman:  yeah, the 2014 version of the N7 is HD
2014-03-06T07:04:56 < dongs> tablets in general are fucking useless.
2014-03-06T07:05:03 < englishman> 2013 :)
2014-03-06T07:05:06 < englishman> mine is laptop replacement
2014-03-06T07:05:08 < englishman> very useful
2014-03-06T07:05:13 < tp> dongs:  would have agreed once, before the N7
2014-03-06T07:05:26 < dongs> tp, i have n7. its useless for anything
2014-03-06T07:05:33 < tp> englishman the 2013 N7 wasnt HD ?
2014-03-06T07:05:48 < dongs> there are 2 dixus7
2014-03-06T07:05:51 < dongs> old shit that was 720
2014-03-06T07:05:52 < tp> dongs does yours have 3G wireless ?
2014-03-06T07:05:59 < dongs> and new thats 1900x1200
2014-03-06T07:06:01 < englishman> 2012 is old one
2014-03-06T07:06:04 < tp> ahh
2014-03-06T07:06:07 < dongs> tp, its irrelevant, it would never leave the house anyway.
2014-03-06T07:06:17 < dongs> can't find a single use case for that shit
2014-03-06T07:06:19 < dongs> not. one.
2014-03-06T07:06:21 < tp> well maybe it took a extra year to reach Australia ? ;-)
2014-03-06T07:06:27 < englishman> do you ever lave the house?
2014-03-06T07:06:34 < tp> me, all the time
2014-03-06T07:06:54 < englishman> hooray!
2014-03-06T07:06:58 < tp> and as I'm 59, I need a larger display, eyes not what they used to be
2014-03-06T07:07:38 < aadamson> night all thanks for the HELP! :)
2014-03-06T07:07:44 < tp> I get emails, view calendar, read ebooks on Kindle App, or FBreader, share my ebook collection over my WiFi via Calibre

2014-03-06T07:08:42 < englishman> more book like
2014-03-06T07:08:53 < dongs> i prefer not reading books
2014-03-06T07:08:57 < dongs> less trouble tht way
2014-03-06T07:08:59 < tp> englishman:  I used to, but the Ny display, with FBreader is fine for me
2014-03-06T07:09:06 < dongs> isnt fbreader opensores
2014-03-06T07:09:12 < dongs> i installed that once, lasted maybe 30 seconds
2014-03-06T07:09:19 < dongs> UI was completely unusable on anything hidpi
2014-03-06T07:09:30 < tp> I have a Kindle 3g paperwhite with 3G, and once thought it was the top device
2014-03-06T07:10:02 < tp> Yes, Fbreader is GPLD'd windows boi
2014-03-06T07:10:18 < dongs> so basically trash
2014-03-06T07:10:28 < tp> fact is, the N7 is faster, better display, really useful
2014-03-06T07:10:33 < englishman> cool eink display in 1440 x 1080
2014-03-06T07:10:37 < dongs> faster for what
2014-03-06T07:10:40 < tp> haha, nah if it was trash, it would run WINCE
2014-03-06T07:10:42 < dongs> better for what
2014-03-06T07:10:48 < englishman> can open gmail so fast
2014-03-06T07:10:52 < dongs> < tp> I get emails, view calendar, read ebooks on Kindle App, or FBreader, share my ebook collection over my WiFi via Calibre
2014-03-06T07:10:58 < dongs> my phone gets email too
2014-03-06T07:11:03 < dongs> and actually fits in my pocket
2014-03-06T07:11:11 < tp> windows phone for loozers ?
2014-03-06T07:12:01 < tp> I have a N7 nokia phone, Harmattan amd OLED
2014-03-06T07:12:37 < tp> it's a decent size and ok for a phone, prefered it to my Samsung S3 which I gave away, hate the UI
2014-03-06T07:13:20 < tp> englishman:  I do love eink, have about 5 eink ebook readers Ive collected over the years
2014-03-06T07:14:09 < tp> but they are usually too slow for me, hence I prefer the N7 as a reader, decent large screen, hi HD res
2014-03-06T07:14:24 < tp> plus also does all the phone stuff, inc voip

2014-03-06T08:05:43 < dongs> its an 'industry standard" pciE multiplexer
2014-03-06T08:06:22 < dongs> it even comes in 2 types
2014-03-06T08:06:26 < dongs> pinout A and B
2014-03-06T08:06:30 < dongs> one for ATX one for BTX
2014-03-06T08:06:33 < dongs> both insane
2014-03-06T08:06:53 < dongs> i cant see any fucking reason why portA and B would be interleaed like that
2014-03-06T08:06:57 < dongs> just makes routing fucktarded
2014-03-06T08:07:49 < GargantuaSauce> doesnt anything using pcie have approximately 900 layers anyway
2014-03-06T08:08:02 < dongs> how does layer help this? :)
2014-03-06T08:08:19 < dongs> im sure routing 5ghz signals through vias is a very cool idea
2014-03-06T08:08:31 < ds2> for your next board, work with all 0201
2014-03-06T08:08:42 < dongs> ^ ds2 is the 0201 pro
2014-03-06T08:08:45 < dongs> ds2: hows that wlcsp
2014-03-06T08:09:11 < ds2> don't like the xtal
2014-03-06T08:09:16 < dongs> aha.
2014-03-06T08:09:22 < ds2> Silabs seems to have something more to my taste
2014-03-06T08:09:28 < ds2> but it is 6mmx6mm
2014-03-06T08:09:43 < ds2> OTH, it can run with an accurate external RC
2014-03-06T08:09:50 < dongs> ...
2014-03-06T08:10:00 < dongs> external rci s ok but a crystal and 2 caps that take up 2x2mm is not ok?
2014-03-06T08:10:09 < ds2> there is the other factor

2014-03-06T08:10:16 < ds2> the silabs part has a cross bar switch on the pins
2014-03-06T08:10:20 < ds2> simplifies routing
2014-03-06T08:10:25 < dongs> right
2014-03-06T08:10:30 < dongs> that shit is pretty awsm
2014-03-06T08:10:32 < ds2> the stm32 means I got to jump around to get it routed
2014-03-06T08:11:01 < dongs> nexxt step with slabs they should make it so you can mount it in any orientation
2014-03-06T08:11:02 < dongs> and it still wokrs
2014-03-06T08:11:18 < dongs> then you can just like throw some shit on a board and itll wokr.
2014-03-06T08:11:30 < ds2> heh....4 quadr in the center for VCC/GND
2014-03-06T08:11:34 < dongs> yes
2014-03-06T08:11:40 < upgrdman> cross bar switch?
2014-03-06T08:11:51 < dongs> upgrdman: you can assign pretty much any peripheral to any pin
2014-03-06T08:12:11 < dongs> not fixed stuff like stm32 AF
2014-03-06T08:12:24 < upgrdman> oh neat
2014-03-06T08:12:31 < ds2> more importantly, you don't loose functions due to a bad pinmux choice
2014-03-06T08:12:46 < dongs> that too.
2014-03-06T08:12:58 < ds2> only drawback I see is finding a cheap SWD debugger for it
2014-03-06T08:13:04 < dongs> wat?
2014-03-06T08:13:11 < dongs> whats stopping you from using stlink

2014-03-06T10:54:18 < dongs> http://www.maximintegrated.com/datasheet/index.mvp/id/5769 is same pinout and says specifically its bidirectional
2014-03-06T10:59:14 < dongs> also this All signal paths are implemented using high-bandwidth pass-gate technology, are bidirectional and no clock or reset signal is needed for the multiplexer to function.
2014-03-06T10:59:32 < dongs> "are bidirectional" is pretty clear right?
2014-03-06T10:59:42 < dongs> wonder why they dont specifically say it tho.

2014-03-06T22:21:25 < tkoskine> karlp: I am using https://launchpad.net/gcc-arm-embedded/4.8/4.8-2013-q4-major/+download/gcc-arm-none-eabi-4_8-2013q4-20131204-linux.tar.bz2 and github.com/libopencm3-examples. I am trying to get examples/stm32/f4/stm32f4-discovery/miniblink on stm32f405.
2014-03-06T22:21:59 < tkoskine> https://github.com/libopencm3/libopencm3-examples I mean.
2014-03-06T22:22:57 < tkoskine> I have modified stm32f4-discovery.ld to have rom (rx) : ORIGIN = 0x08000000, LENGTH = 1024K, ram (rwx) : ORIGIN = 0x20000000, LENGTH = 192K

2014-03-06T22:27:49 < tkoskine> Code seems to jump to error handler near bl, movw, and push instructions (I am not totally sure how to interpret openocd stepping, is the reported location already executed or will it be executed when next 'step' command is given?)
2014-03-06T22:31:48 < tkoskine> It is also totally possible that I am mixing toolchains :). I have one installed globally via package manager, and then I have that gcc-arm-embedded toolchain in a separate directory, and few others.

2014-03-07T01:07:55 < synic> so what's the 32Mhz crystal for?
2014-03-07T01:08:02 < zyp> ah, right

2014-03-07T02:03:24 < emeb> zyp: hello
2014-03-07T02:03:29 < emeb> wazzup?
2014-03-07T02:04:16 < zyp> I started doing that fpga design
2014-03-07T02:04:24 < zyp> but I think I forgot what I was gonna ask about
2014-03-07T02:04:51 < zyp> http://bin.jvnv.net/f/oHIPM.png
2014-03-07T02:05:28 < emeb> whee... FPGAs
2014-03-07T02:05:28 < zyp> right, IO banks, should I be concerned about which signals I put in which banks when all banks are running same IO voltage anyway?
2014-03-07T02:06:05 < zyp> now I've just put anything anywhere
2014-03-07T02:06:05 < emeb> I wouldn't worry about it if the IO voltages are the same.
2014-03-07T02:06:20 < emeb> I just route signals to pins for the best layout
2014-03-07T02:06:31 < zyp> no concerns about timing skew between banks?
2014-03-07T02:06:44 < zyp> yeah, that's what I did
2014-03-07T02:07:08 < emeb> Well, if you have buses that are running synchronously it's nice to co-locate if possible
2014-03-07T02:07:22 < emeb> and that usually puts things into the same or adjacent banks
2014-03-07T02:07:35 < emeb> the timing tools can help you manage skew
2014-03-07T02:07:37 < zyp> I have two 16-bit buses here
2014-03-07T02:07:57 < emeb> ie - you can constrain the signals in the buses to have similar timing to within a tolerance
2014-03-07T02:08:14 < emeb> and the synthesis process will work to enforce that timing...
2014-03-07T02:08:24 < zyp> the vertical headers are fsmc, data on left side, addr on right side
2014-03-07T02:08:34 < zyp> and the connector at the top is PATA
2014-03-07T02:09:28 < emeb> seems reasonable.
2014-03-07T02:10:03 < emeb> if you have tight constraints on the IO timing it might be wise to do a "straw man" design in the FPGA tools to see if your pin assignments will be realizable.

2014-03-07T02:10:20 < emeb> I often did that on questionable situations
2014-03-07T02:10:52 < zyp> I'm intending to use slave parallel, so I put D0-7 and chip select on the matching pins and write latch on CCLK
2014-03-07T02:10:52 < emeb> because sometimes even IO assignments within the same bank can be problematic depending on the internal routing
2014-03-07T02:11:23 < emeb> what size FPGA?
2014-03-07T02:12:01 < zyp> either 50A or 200A depending on how big the configuration will be, footprints are compatible
2014-03-07T02:12:18 < zyp> (or even 400A)
2014-03-07T02:12:40 < zyp> XC3S50A that is
2014-03-07T02:12:47 < emeb> configuration on parts that small goes pretty fast even when it's serial - do you really need the parallel configuration?
2014-03-07T02:13:12 < zyp> no, I'm not really concerned about that
2014-03-07T02:13:25 < zyp> but when I'm running a parallel bus anyway, why not
2014-03-07T02:13:40 < emeb> I see.
2014-03-07T02:14:06 < emeb> so you're using the BGA package?
2014-03-07T02:14:44 < zyp> yes, 100qfp doesn't have enough IO and 144qfp only exists for 50A, not 200A
2014-03-07T02:15:29 < dongs> stoned
2014-03-07T02:15:57 < zyp> and since I've already done 1mm pitch 256bga at home before, I'm not afraid to do it again
2014-03-07T02:16:50 < emeb> or you could get the S6 LX9 in the 144 - it's pretty cheap and has a bit more logic than the 200A
2014-03-07T02:17:12 < dongs> and has PCIe
2014-03-07T02:17:33 < dongs> or ddr2, i forgot which
2014-03-07T02:18:03 < emeb> I don't think the QFP versions of the S6 have the DDR and PCI cores
2014-03-07T02:18:24 < emeb> but S6 does have some other nice features beyond S3A that might be useful... or not.
2014-03-07T02:19:05 < emeb> ie - true PLLs for cleaner clocks and DSP48 blocks for math operations.
2014-03-07T02:19:09 < zyp> hmm, there's no advantage in price
2014-03-07T02:19:33 < zyp> and 144qfp is larger :)
2014-03-07T02:20:05 < emeb> yeah - just depends on what you're comfortable with. If you <3 BGA then go for it. :)
2014-03-07T02:20:30  * emeb fears the BGA for home-made stuff...
2014-03-07T02:21:35 < zyp> so far I've got 100% yield on the BGA boards I've done, that's better than both QFP and QFN :p
2014-03-07T02:21:49 < dongs> aligning a giant 144pin qfn is actually harder...
2014-03-07T02:22:02 < dongs> er qfp
2014-03-07T02:22:08 < zyp> if only 3 was a statistically significant number :p
2014-03-07T02:23:21 < emeb> I guess that's true - the 1mm BGA pitch is more forgiving than 0.5mm QFP.
2014-03-07T02:25:09 < ds2> how's the yield on the 0.4mm BGAs? ;)
2014-03-07T02:25:34 < zyp> 3S50A is $9.7, 3S200A is $14.9, 6SLX9 starts at $15.7
2014-03-07T02:25:45 < emeb> yeah
2014-03-07T02:26:03 < zyp> not a huge difference between 200A and LX9
2014-03-07T02:26:05 < emeb> but the 6SLX9 has a lot more goodies than the 3S200A
2014-03-07T02:26:15 < zyp> but I doubt I require that much anyway
2014-03-07T02:26:50 < emeb> well, I've found that FPGA resources are like memory - it's always best to get the biggest the budget will allow. :)
2014-03-07T02:27:08 < emeb> you never know what you might want/need to do with it...
2014-03-07T02:27:15 < zyp> unless you're producing in volume ;)
2014-03-07T02:27:29 < emeb> that's why I said "budget will allow"
2014-03-07T02:27:58 < zyp> high volume budgets won't allow anything but the cheapest that performs to spec ;)
2014-03-07T02:29:02 < emeb> but if you were trading off 6SLX9 vs 3S200A that $0.8 vs the increase in resources might be worthwhile in volume...

2014-03-07T02:43:29 < zyp> emeb, what should I do about clocking? would it be good enough to feed the FPGA from MCO from the microcontroller?

2014-03-07T03:23:15 < dongs> NXP.s new LPC1500 Cortex-M3 microcontroller family is the perfect route to simpler motion control circuit design. A dedicated hardware and firmware solution, the LPC1500 makes it easy to tune, calibrate and control multiple different motors . whether sensored or sensorless, brushed or brushless, AC or DC.
2014-03-07T03:29:54 < dongs> http://www.nxp.com/documents/data_sheet/LPC15XX.pdf wow feature list looks pretty good

2014-03-07T04:52:18 < dongs> when it was in teh rack it would barely last like 2 minutes. i think the xeons + other crap in it was drawing way too much

2014-03-07T07:42:13 < dongs> software on PC sends shit to the dongle like user is pressing shit on keyboard.
2014-03-07T07:42:49 < zyp> yes
2014-03-07T07:43:17 < zyp> but I mean, HID stuff and all that is higher level shit, so that shouldn't be limited by the hardware

2014-03-07T07:44:32 < dongs> that too
2014-03-07T07:44:35 < zyp> if you're going with a keycombo to control it, why not put it inline between the keyboard and pc instead?
2014-03-07T07:44:39 < dongs> thats special perk for dickstarter backers
2014-03-07T07:44:52 < dongs> zyp, !
2014-03-07T07:45:07 < dongs> now there's some innovation in progress
2014-03-07T07:45:12 < zyp> F4 already has two usb controllers, so it can sit inline
2014-03-07T07:45:24 < zyp> then you only need the BT interface on that
2014-03-07T07:45:33 < emeb_mac> man in the middle
2014-03-07T07:45:36 < zyp> yeah
2014-03-07T07:45:47 < emeb_mac> ATTACK!
2014-03-07T07:45:55 < dongs> sounds like dickstarter time
2014-03-07T07:46:01 < dongs> business plan is ready.
2014-03-07T07:46:07 < englishman> just make sure it's android compatible
2014-03-07T07:46:23 < emeb_mac> and has arduino headers
2014-03-07T07:46:25 < dongs> < englishman> just make sure it's arduino compatible
2014-03-07T07:46:27 < dongs> ^ ftfy
2014-03-07T07:46:52 < zyp> it's hard to relate it to arduino or rpi :(
2014-03-07T07:46:53 < englishman> oh shit
2014-03-07T07:46:55 < englishman> right
2014-03-07T07:47:03 < englishman> thats  actualyl what i meant to type
2014-03-07T07:47:07 < englishman> sleep time i think
2014-03-07T07:47:22 < dongs> BT keyboard for raspnberrypi
2014-03-07T07:47:44 < dongs> keylogger for arduino
2014-03-07T07:47:49 < dongs> zyp, the inline shit sounds great. hmm.
2014-03-07T07:47:56 < dongs> does 64pin F4 have both usbs on it?
2014-03-07T07:47:59 < dongs> or is that only in the huge one
2014-03-07T07:48:00 < zyp> yes
2014-03-07T07:48:18 < englishman> just use two pic18
2014-03-07T07:48:25 < dongs> attiny325
2014-03-07T07:48:32 < dongs> with LUFA or wahtever.
2014-03-07T07:48:35 < emeb_mac> bitbang all the things
2014-03-07T07:48:36 < dongs> amazeballs.
2014-03-07T07:48:38 < zyp> vusb
2014-03-07T07:48:58 < zyp> keyboards are low speed anyway, should be easy to bitbang :p
2014-03-07T07:48:58 < dongs> what ever happened to vusb getting ported to stm32
2014-03-07T07:49:16 < zyp> dunno, I'm certainly not gonna do it
2014-03-07T07:49:17 < dongs> so you can have a USB device on every pin
2014-03-07T07:49:33 < emeb_mac> well, every two pins...
2014-03-07T07:49:50 < dongs> minor detail
2014-03-07T07:50:10 < zyp> but I've been tempted to do virtual hubs a couple of times
2014-03-07T07:50:19 < dongs> they did that in vusb
2014-03-07T07:50:22 < dongs> for the ps3hax shit
2014-03-07T07:52:32 < zyp> thought about this earlier today; small board with two stm32s, one running a debugger firmware, the other being a target, both available on usb
2014-03-07T07:52:43 < zyp> matchboxarm killer?
2014-03-07T07:52:53 < dongs> omg yes
2014-03-07T07:52:55 < zyp> oh, I forgot, matchboxarm was dead already
2014-03-07T07:53:03 < dongs> (you just described stm32 nucleo)
2014-03-07T07:53:59 < dongs> Got the board, but it seems there is no documentation or so to get started. Coocox is not an option, as I am on a Mac - I've used the mbed compiler before though and it looks very similar. Could someone check if the mbed cloud compile supports this board and post an example maybe?
2014-03-07T07:54:25 < dongs> For those of you wanting to get on with some development while waiting for your MatchboxARM, there are some almost equivalent boards available on ebay from China. They're a bit bigger and not so pretty, but they use the same processor and have all the IO pins available. Search on ebay for "ARM Cortex-M3 STM32F103C8T6 STM32 Minimum System Development Board". They cost from around £6.50 delivered
2014-03-07T07:55:33 < qyx_> "not so pretty"
2014-03-07T07:55:42 < GargantuaSauce> All you backers, by end of March everyone should have their gift. That its the final date. :)
2014-03-07T07:55:44 < zyp> it's not red enough
2014-03-07T07:55:47 < GargantuaSauce> >gift
2014-03-07T07:56:56 < qyx_> it's more blue
2014-03-07T07:59:56 < dongs> what about BT stuff? those serial breakout shits wouldnt work rihgt?
2014-03-07T08:00:43 < dongs> configuration could be fun
2014-03-07T08:00:47 < dongs> open notepad and press button
2014-03-07T08:00:54 < dongs> and it types stuff, like menu etc
2014-03-07T08:00:59 < dongs> then you type stuff back.
2014-03-07T08:04:36 < dongs> hm doenst one of USB shits on F4 need extenral phy
2014-03-07T08:04:41 < dongs> or is that onyl for highspeed

2014-03-07T08:06:34 < zyp> only for highspeed, yes
2014-03-07T08:06:55 < zyp> I'm using the internal phy on that on my quadrotor board
2014-03-07T08:07:09 < zyp> which is 64-pin package and everything
2014-03-07T08:07:34 < dongs> hm
2014-03-07T08:07:36 < dongs> so what about BT
2014-03-07T08:07:42 < dongs> seems wasteful to put one of those norDICK chips on there
2014-03-07T08:07:47 < dongs> which will be yet another cortex-M to deal with
2014-03-07T08:07:54 < dongs> :|
2014-03-07T08:07:55 < zyp> dunno
2014-03-07T08:08:06 < zyp> nrf518 is only btle
2014-03-07T08:08:30 < zyp> and you don't really need the low energy part for a usb powered device
2014-03-07T08:08:48 < dongs> heh yeah.
2014-03-07T08:08:49 < dongs> hm
2014-03-07T08:09:02 < dongs> well, TI shit, but thats 8051 filth

2014-03-07T08:25:33 < dongs> do you think if I hookup +/- in reverse to differential pairs, will it still wokr? its just a switch right. so like who cares?
2014-03-07T08:28:37 < emeb_mac> as long as you reverse it twice (on input & output, or input and dest, etc) it should be ok
2014-03-07T08:31:09 < dongs> right
2014-03-07T08:31:43 < dongs> free space on 2L/enig getting wasted
2014-03-07T08:31:47 < dongs> no time to innovate anything
2014-03-07T08:33:23 < emeb_mac> put down some more JTAG adapters
2014-03-07T08:33:31 < dongs> haha
2014-03-07T08:33:35 < dongs> i still have a shitload in a bag
2014-03-07T08:36:14 < emeb_mac> do some of my F373 breakouts - I've had a bunch of folks ask for them. You could sell them on abusemark
2014-03-07T08:37:25 < dongs> 373? isnt that chip dead
2014-03-07T08:37:46 < emeb_mac> wat? why dead?
2014-03-07T08:38:04 < dongs> what do people want 373 for isntead of 303

2014-03-07T08:46:34 < dongs> against datasheet
2014-03-07T08:46:44 < dongs> first its g onna be 2:1 mux instead of 1:2
2014-03-07T08:46:51 < dongs> and then i'm gonna swap +/- on every lane
2014-03-07T08:46:55 < dongs> otherwise routing is idiotic
2014-03-07T08:47:01 < dongs> *every* lane ends up backwards
2014-03-07T08:47:40 < dongs> datasheet also says from IN+ to D0/TX0 but again if its analog switches i dont see why it cant go in reverse
2014-03-07T08:47:59 < dongs> maxim has a pin compatible part that does specifically say its bidirecitonal

2014-03-07T12:33:44 < jpa-> of course, the stdperiph has a lot of sucky parts.. that's why i only use the header

2014-03-07T12:34:03 < qyx_> maybe thats the cause
2014-03-07T12:34:23 < jpa-> qyx_: doesn't matter, as long as a part of chibios is gpl, you cannot combine it with non-gpl stdperiph
2014-03-07T12:34:37 < jpa-> though how that applies to header files is open to interpretation

2014-03-07T13:39:26 < dan2003> anybody know howto recover from TX mailbox full when using CAN modules? AS soon as i hit this error when sending all subsequent send attempts fail with same error, and there is no bus activity.
2014-03-07T13:41:22 < dan2003> example of getting into this state, while sending msgs happily indefinitely,  cause a temporary bus fault, e.g. short it,  mailboxes then fill up and problem occurs

2014-03-07T14:32:31 < qyx_> you have sizes in the contents section
2014-03-07T14:33:22 < dongs> another thing that really pisses me off with dicktrace is whenver yo uswitch units it will sometime round off last 3rd/4th digit in between conversions

2014-03-07T14:49:56 < dongs> no they should have startup file
2014-03-07T14:49:57 < karlp> what? no, it totally has startup files
2014-03-07T14:50:02 < dongs> cuz they renamed all vector names ands hit

2014-03-07T14:51:43 < fbs> so it should work without startup files?
2014-03-07T14:51:49 < dongs> ??
2014-03-07T14:52:07 < karlp> I agree it was a bad choice to rename the arm cortex nvic names, but I've got nothing against renaming the st periph irqs
2014-03-07T14:52:53 < jpa-> renaming stuff is stupid, just makes code more difficult to copypaste!
2014-03-07T14:53:16 < dongs> pfft
2014-03-07T14:53:27 < karlp> you couldn't copy/paste it anyway,

2014-03-07T14:53:58 < jpa-> IMO there is nothing wrong with the stdperiph register names

2014-03-07T15:59:16 < dongs> (the underlined alt-foo stuffs
2014-03-07T15:59:32 < dongs> so now most of their right click menus dont work by keyboard
2014-03-07T15:59:33 < dongs> gota click

2014-03-07T16:00:05 < dongs> rational was it conflicted with "global" hotkeys or something, sounds like some delphi fail excuse
2014-03-07T16:03:02 < englishman> some things are really annoying in altium too
2014-03-07T16:03:22 < dongs> like?
2014-03-07T16:03:24 < englishman> but then i realized the same flaqs were in diptrace, they were just handlded differently and i didnt know the tricks yet
2014-03-07T16:03:30 < englishman> like pours not updating
2014-03-07T16:03:36 < englishman> when you move shit
2014-03-07T16:03:50 < englishman> oh, when you start routing, enable hugs mode
2014-03-07T16:03:50 < dongs> "new" diptrace will have automatic pour updates
2014-03-07T16:03:54 < englishman> hugs are awesome
2014-03-07T16:04:01 < englishman> so, doesnt exist yet
2014-03-07T16:04:04 < englishman> like osdongs
2014-03-07T16:04:08 < englishman> it "will" be awesome
2014-03-07T16:04:13 < dongs> new diptrace cancelled due to kiev war
2014-03-07T16:08:04 < karlp> what war?
2014-03-07T16:08:29 < dongs> world war 3 or whatever
2014-03-07T16:08:49 < qyx_> still not worldy enough

2014-03-07T16:23:00 < englishman> did you  buy?
2014-03-07T16:23:25 < dongs> you wish. i will once tehy have a version that desnt require me to learn fpga
2014-03-07T16:23:31 < dongs> and once its ~1k
2014-03-07T16:23:32 < englishman> yaeh
2014-03-07T16:23:49 < englishman> well the rumours are aboud about free gateway version like eagle
2014-03-07T16:24:01 < englishman> otherwise noone would use altium til they get to a company that needs/can afford it
2014-03-07T16:24:27 < dongs> i dont care about freetard version
2014-03-07T16:24:43 < dongs> but i have no interest in fpga compiler, spice sim, or any other garbage it comes with ill never use
2014-03-07T16:24:52 < englishman> well free version probably means stepping stone versions too
2014-03-07T16:24:55 < dongs> schematic capture + pcb layout, thanks
2014-03-07T16:24:59 < englishman> ^ like that
2014-03-07T16:35:45 < dongs> but can you color nets in altium? :(
2014-03-07T16:36:24 < englishman> not in layout that i know of
2014-03-07T16:36:26 < fbs> you can
2014-03-07T16:36:29 < englishman> in schematic maybe

2014-03-07T16:38:37 < Laurenceb_> i was thinking of zigbee on steroids or something
2014-03-07T16:39:00 < Laurenceb_> theres got to be something off the shelf
2014-03-07T16:39:10 < fbs> jpa-: do you have a 'template' toolchain you can share? Interested in seeing how you did the stm libs stuff
2014-03-07T16:39:32 < qyx_> Laurenceb_: try ubiquity airmax nanobridge/nanostation
2014-03-07T16:39:39 < qyx_> on 5GHz
2014-03-07T16:39:46 < jpa-> fbs: uh.. i just took the stm32xxxx.h from the stdperiph and used it.. (and the few other .h that it needs, nvic something etc.)
2014-03-07T16:40:01 < Laurenceb_> qyx_: ok

2014-03-07T16:41:06 < qyx_> 10km is not a problem for 5G wifi if LOS is available
2014-03-07T16:41:43 < fbs> jpa-: and you manually implement gpio_toggle and stufF?
2014-03-07T16:42:27 < Laurenceb_> wow
2014-03-07T16:42:35 < Laurenceb_> i wasnt expecting such a low price
2014-03-07T16:42:44 < Laurenceb_> zigbee is $500
2014-03-07T16:44:00 < jpa-> fbs: uh.. "implement" as in "write GPIOB->ODR = something"  .. yes
2014-03-07T16:44:06 < jpa-> fbs: though a lot of time i just use chibios
2014-03-07T16:46:27 < fbs> yea should look into chibi
2014-03-07T16:50:26 < qyx_> if the licensing is not a problem, it is quite feasible alternative

2014-03-07T21:21:52 < madist> yes, obviously i know less than very little about this subject :)
2014-03-07T21:23:05 < Bird|ghosted> on the programming side: the bootloader on my microcontroller (LPC11U37) requires a checksum of the first 8 vector entries to be stored in vector table entry #7 in order to recognize user code as valid
2014-03-07T21:23:52 < Bird|ghosted> my question: where do they expect me to compute this checksum?  the compiler tosses its cookies if asked because the addresses of functions aren't compile-time constants
2014-03-07T21:24:58 < PaulFertser> Bird|ghosted: openocd computes the checksum on its own while flashing
2014-03-07T21:25:23 < PaulFertser> Bird|ghosted: or you can add an external utility to your makefile that would embed it into the binary.
2014-03-07T21:26:43 < Bird|ghosted> PaulFertser: having to play 'scribble on the binary' games is...unpleasant, to say the least
2014-03-07T21:26:44 < Steffanx> He was here yesterday mr madist ...
2014-03-07T21:26:52 < Steffanx> He did ask questions mr madist
2014-03-07T21:27:12 < Bird|ghosted> PaulFertser: also: I'm referring to a direct bootload, not via openocd :P
2014-03-07T21:27:22 < Bird|ghosted> (the LPC11U37 has a USB bootloader in ROM)
2014-03-07T21:27:22 < madist> o
2014-03-07T21:27:55 < Steffanx> need more information mr madist?
2014-03-07T21:28:04 < Bird|ghosted> also, speaking of checksums, how valuable is checksumming one's Flash at boot-time in this day and age?
2014-03-07T21:28:08 < madist> mmm... let me get back to you on that.
2014-03-07T21:28:24 < PaulFertser> Bird|ghosted: I do not think ld can do any complex computations
2014-03-07T21:28:55 < Bird|ghosted> PaulFertser: actually, it can!
2014-03-07T21:29:19 < PaulFertser> Bird|ghosted: hm, yes, just checked, 3.10.6 operators
2014-03-07T21:35:08 < PaulFertser> Bird|ghosted: if you figure it out and document somewhere, please, highlight me and I'll add a link to OpenOCD docs.
2014-03-07T21:36:12 < Bird|ghosted> PaulFertser: the checksumming? the checksum itself is documented in Ch.20 of the LPC11Uxx user's manual
2014-03-07T21:39:25 < PaulFertser> Bird|ghosted: I hoped you'd figure out how to write an .ld script snippet to do that automatically link-time ;)
2014-03-07T21:41:37 < Bird|ghosted> ah ;)
2014-03-07T21:41:46 < Bird|ghosted> I've got an idea of how to do it
2014-03-07T21:42:18 < Bird|ghosted> but I'm not sure if creating a symbol that points blithely into nowhere for this purpose is at all a good idea
2014-03-07T21:44:46 < PaulFertser> Bird|ghosted: why not?
2014-03-07T21:46:42 < Bird|ghosted> PaulFertser: its just...odd. :p but I suppose its the best solution, considering that to do otherwise would require sending the location counter everywhichaway
2014-03-07T21:50:27 < PaulFertser> Bird|ghosted: btw, do you plan on doing interactive target debugging with that chip? What hardware are you planning to use?
2014-03-07T21:51:23 < Bird|ghosted> PaulFertser: re: debug: yes, and I have both the ST-Link SWD on my F0 Discovery board and a BusBlaster with the KTLink buffer programmed into it
2014-03-07T21:52:28 < PaulFertser> Bird|ghosted: great. OpenOCD got experimental swd support for ftdi adapters recently, so that ktlink-compatible config should work too.

2014-03-07T21:57:31 < fbs> anyone got a cool script to connect gdb to openocd?
2014-03-07T21:58:05 < PaulFertser> fbs: "tar ext :3333" is enough
2014-03-07T21:59:09 < fbs> yea i guess
2014-03-07T22:00:38 < fbs> ould be nice if i could start openocd and stop it when gdb exits

2014-03-08T03:20:23 < dongs> yes
2014-03-08T03:20:34 < dongs> it means it selects a channel, then samples it.
2014-03-08T03:20:47 < dongs> you have something like ADC1_CH1/2/3/4..16
2014-03-08T03:20:57 < dongs> means you can only read one at a time.
2014-03-08T03:21:16 < Fleck> ohh, nice, so you can have for example 16 different inputs, and select/capture them one by one?

2014-03-08T16:16:33 < dongs> right
2014-03-08T16:16:36 < dongs> thats what i am doing
2014-03-08T16:16:46 < dongs> adding a bunch seems just way too much work
2014-03-08T16:17:38 < talsit> meh, i've added all my common parts, plus a range of generics
2014-03-08T16:25:28 < dongs> 'range'?
2014-03-08T16:25:37 < dongs> i dont see how i would ever need more than one res or cap
2014-03-08T16:25:46 < talsit> 0402, 0603, etc
2014-03-08T16:25:51 < dongs> you dont even ened that
2014-03-08T16:25:57 < dongs> R can have different footprints
2014-03-08T16:26:04 < dongs> you can just place one down, choose footprint then copy it all over.
2014-03-08T16:26:17 < zyp> the problem with doing all resistors as one is that the smartbom feature or what it was called fails
2014-03-08T16:26:36 < dongs> thats not really a problem if you dont plan to us it tho?
2014-03-08T16:26:38 < dongs> what does it do
2014-03-08T16:26:40 < zyp> because it assumes that each components are the same part everywhere
2014-03-08T16:27:00 < zyp> it couples your part database to prices from distributors
2014-03-08T16:27:06 < dongs> pffft
2014-03-08T16:27:11 < dongs> i already hae partskeeper for that
2014-03-08T16:27:17 < dongs> and im not gonna count resistors costs
2014-03-08T16:27:21 < dongs> its $5/reel
2014-03-08T16:27:25 < zyp> :p
2014-03-08T16:31:52 < dongs> how come even shit like 'value is in custom attributes
2014-03-08T16:34:05 < dongs> er, parameters
2014-03-08T16:34:09 < dongs> and default fonts are soo huge
2014-03-08T16:34:39 < talsit> you can change the default

2014-03-08T16:49:22 < Steffanx> i was just wondering how low power it actually is zyp
2014-03-08T16:49:48 < zyp> depends on what you do with it
2014-03-08T16:50:11 < dongs> many dickstarter projects guarantee years of life off a single battery
2014-03-08T16:50:21 < dongs> ^ ble
2014-03-08T16:50:30 < zyp> yeah
2014-03-08T16:50:30 < Steffanx> Saw some wonderful dices with bluetooth LE in some local newspaper
2014-03-08T16:50:58 < dongs> role dice?
2014-03-08T16:51:01 < zyp> low power is a result of spending most of the time asleep
2014-03-08T16:51:01 < Steffanx> Yes.
2014-03-08T16:51:06 < Steffanx> Yes of course.

2014-03-08T16:52:48 < Steffanx> then use your phone ( if it does BLE)

2014-03-08T17:00:15 < dongs> would be more innovative if it used torque from a pager motor to force itself to land on a particular face
2014-03-08T17:00:22 < dongs> so yo ucould cheat
2014-03-08T17:00:51 < Steffanx> :P
2014-03-08T17:00:58 < dongs> what problem is it trying to solve

2014-03-08T17:01:55 < dongs> or does yahtzee rquire some zero-second dice telemetry to suceed
2014-03-08T17:02:21 < karlp> it solves having to add up the faces yourself

2014-03-08T17:08:03 < karlp> anyone know how to make git checkout blah actually checkout the right versions of submodules properly, instead of leaving them as is, and saying that I have a modified submodule?
2014-03-08T17:09:55 < zyp> it should do that already unless your submodule is dirty
2014-03-08T17:10:46 < karlp> hrmm, yeah, that must be it, submodules don't like having untracked files in them :(
2014-03-08T17:10:54 < karlp> makes git bisect a bit tedious :)
2014-03-08T17:11:38 < zyp> that's what you get for not getting .gitignore right in the first place :p
2014-03-08T17:12:06 < karlp> well, it's a directory that I plan on adding to the submodule, it's just not ready yet.
2014-03-08T17:12:13 < karlp> but yeah, ok, pilot error, I can deal with that :)
2014-03-08T17:12:34 < zyp> keeping uncommitted changes around while bisecting? bad idea
2014-03-08T17:12:43 < zyp> commit them to a temporary branch instead
2014-03-08T17:18:29 < karlp> well, without submodules it just leaves them there
2014-03-08T17:18:40 < karlp> not really uncommited _changes_ just an entire directory that's never been added to git
2014-03-08T17:19:26 < karlp> also, why am I bisecting at all, I sat down to fix my own usb problems, not this crap
2014-03-08T17:23:18 < karlp> nope, committed or removed everything in the submodule, and git bisect didn't update it.

2014-03-08T20:25:50 < aadamson> yeah, you only need the clocks before you use them
2014-03-08T20:25:56 < aadamson> whenever that is
2014-03-08T20:26:06 < aadamson> but be careful there are interrelated clocks sometimes

2014-03-08T20:27:34 < Bird|ghosted> aadamson: I'd figure you'd want to turn on those clocks rather early so that you could use debug outputs and suchnot
2014-03-08T20:28:34 < jpa-> if you do, sure, do turn them on early
2014-03-08T20:30:04 < aadamson> yeah, it just all depends on when you need them.

2014-03-08T20:30:50 < aadamson> I can't remember, but it seems to me on the STM's that I never configure the swd pins, but their clocks may be enabled via someother clocks that I've turned on.
2014-03-08T20:31:35 < GargantuaSauce> their default configuration is enabled for obvious reasons
2014-03-08T20:31:39 < englishman> ^
2014-03-08T20:32:09 < GargantuaSauce> check out the reference manual, you'll see the power on state for those pins in the config registers
2014-03-08T20:32:36 < GargantuaSauce> you'd need to enable the clock to disable them, oddly enough

2014-03-09T12:09:15 < dongs> dicking with altium
2014-03-09T12:10:03 < PaulFertser> iirc it had two modes: move and drag, same as with kicad, and move leaves nets as is, while drag keeps them connected.
2014-03-09T12:11:39 < dongs> if there is, i dont see it.
2014-03-09T12:12:09 < PaulFertser> dongs: pcb or sch?
2014-03-09T12:12:53 < dongs> pcb
2014-03-09T12:12:56 < dongs> already fixed it on schematic.
2014-03-09T12:13:22 < dongs> also checked 'comp drag' in preferences, but doesnt seem to ahve an affect
2014-03-09T12:13:23 < dongs> effect
2014-03-09T12:14:15 < PaulFertser> http://www.edaboard.com/thread113158.html
2014-03-09T12:14:31 < PaulFertser> Looks like the only option is to select all the traces along with the component.
2014-03-09T12:15:56 < dongs> saw that thread
2014-03-09T12:15:58 < dongs> its also from 2007

2014-03-09T12:18:15 < PaulFertser> dongs: you should really try Topor, since you do not care about the licences and such, and it's a big timeserver, the boards end up with less layers and vias and you spend less time doing them.
2014-03-09T12:19:30 < qyx_> bleh
2014-03-09T12:20:04 < PaulFertser> I've seen it in action, no kidding.

2014-03-09T12:26:54 < PaulFertser> dongs: I think I've seen him toggling back and forth between topor and p-cad, so that's probably not exactly true. I'll ask him on thursday.

2014-03-09T18:05:15 < scrts> it is designed to work when there are reflections - not sensitive to them
2014-03-09T18:09:09 < Thorn> how does ofdm help against reflections? all frequencies would be reflected imo

2014-03-09T18:17:48 < BrainDamage> reflections cancel out for certain wavelengths while sum for others
2014-03-09T18:18:09 < BrainDamage> using ofdm modulation ensures that you can use the channels for which interference doesn't annoy
2014-03-09T18:18:43 < Thorn> hm, haven't thought about interference
2014-03-09T18:18:53 < Bird|ghosted> so: when bitbanging on an ARM, is the generally accepted approach to spin-wait using a timing loop, wait on a timer interrupt/flag, or to use a timer match output?
2014-03-09T18:19:13 < Bird|ghosted> (I'm implementing a bitbanged UART-output to emulate SWO on the Cortex-M0)
2014-03-09T18:21:44 < zyp> timing loops are rather pointless unless you want only a few cycles worth of delays and don't care too much about accuracy
2014-03-09T18:22:28 < Bird|ghosted> *nods* so, match output or timer interrupt/flag-wait?
2014-03-09T18:22:38 < zyp> if you're singlethreaded and want to block everything anyway, just waiting while polling a timer is an ok option
2014-03-09T18:23:29 < zyp> output compare is also nice if that suits your need
2014-03-09T18:23:51 < Bird|ghosted> zyp: yeah, wiring this up as an interrupt task would be...complex.  (btw: 'match' is the same thing as 'output compare')
2014-03-09T18:24:43 < zyp> yes

2014-03-10T00:39:54 < masa> anyone familiar with the GNU ld and linker scripts?
2014-03-10T00:40:22 < masa> does it always place the stuff linearly, with no gaps, or am I just doing this wrong...
2014-03-10T00:41:08 < masa> I'd like to place one isr vector on a specific location, without having all 100+ vectors present
2014-03-10T00:41:56 < masa> but when I use .= 0x200001cc; in the linker script to presumably set the address before the section, it doesn't have any effect

2014-03-10T00:44:38 < gxti> if you put it inside then it is relative to the start of the section
2014-03-10T00:44:53 < gxti> and you definitely don't have 0x200001cc bytes of RAM
2014-03-10T00:45:34 < masa> ah, right..
2014-03-10T00:45:56 < masa> but shouldn't it work outside of it also? but in that case with the absolute address?
2014-03-10T00:46:56 < gxti> it's probably something about ram sections vs flash ones
2014-03-10T00:47:17 < gxti> i haven't done anything built to run from RAM so i dunno
2014-03-10T00:48:08 < gxti> you can try writing . = 0x1cc inside the section, since it will implicitly be placed from the start of the segment
2014-03-10T00:48:39 < gxti> honestly though i don't think it makes sense to place individual ISRs
2014-03-10T00:49:02 < masa> maybe not, but I would still like to know how to do it
2014-03-10T00:51:05 -!- Viper168 [~Viper@unaffiliated/viper168] has joined ##stm32
2014-03-10T00:51:42 < masa> ok, seems that I got it the right way, at least according to the objdump -D output
2014-03-10T00:52:10 < masa> but I noticed I see to have 464 bytes in the .data section, although I should have none
2014-03-10T00:53:27 < masa> well, nothing in the objdump output, but arm-none-eabi-size still says data 464
2014-03-10T00:55:23 < gxti> that's 4 more than the offset you're placing your ISR at.
2014-03-10T00:55:48 < gxti> if your vector is in ram but isn't .data then what is it?
2014-03-10T00:56:18 < zyp> masa, the size utility isn't always correct in classifying sections into text/data/bss
2014-03-10T01:16:28 < masa> hmm right.. so my ISR vector might get classified as .data then(?)
2014-03-10T01:17:36 < masa> I'm also fuzzy about the linker script syntax, so I'm not quite clear what the section "names" are, or if they are important. I'll have to read the ld manual some more I guess.
2014-03-10T01:18:40 < masa> I mean for example, there is " .text : { *(.text) } >rom ", so what is the first .text, is it just the section name, or is it also important what it reads as?
2014-03-10T01:19:00 < masa> isn't the inner *(.text) what actually places the .text section there?
2014-03-10T01:19:17 < gxti> the first one names the output section
2014-03-10T01:19:22 < gxti> the second one selects sections from all the input files
2014-03-10T01:19:39 < gxti> also do you or do you not have rom?
2014-03-10T01:19:55 < gxti> because earlier you were trying to place text in a RAM address
2014-03-10T01:20:27 < masa> I'm playing around with the stm32vldiscovery, so yes, I have SRAM and Flash, but I'm running my testing stuff from SRAM
2014-03-10T01:20:49 < masa> or at least learning how to do it
2014-03-10T01:21:28 < masa> that is also why I want to place that one word in the end, or past the end of the vector table, for the boot to SRAM to work
2014-03-10T01:22:13 < masa> since the STM32 implements some "special procedure" to be able to boot to SRAM, since that boot mode does not alias the SRAM to 0x0
2014-03-10T01:23:51 < masa> gxti: so what is the output section name used for exactly, and does it have to be .text, .data, .bss for it to actually work?
2014-03-10T01:24:36 < gxti> no it doesn't
2014-03-10T02:09:29 < dongs> cant you just declare RAMFUNC or something for the ISR you want in ram
2014-03-10T02:09:37 < dongs> as long as you don't actually care that its at a specific location...

2014-03-10T02:24:55 < Bird|ghosted> gxti: it really doesn't make sense to try to *place* ISR vectors right that
2014-03-10T02:25:05 < Bird|ghosted> err like that
2014-03-10T02:25:12 < Bird|ghosted> put your vector table in a section
2014-03-10T02:25:19 < Bird|ghosted> and assign a start address for that section
2014-03-10T02:25:29 < Bird|ghosted> then the vectors can be *wherever* provided the vector table points at them
2014-03-10T02:25:52 < gxti> why are you telling me
2014-03-10T02:25:55 < Bird|ghosted> dunno
2014-03-10T02:26:04 < Bird|ghosted> misreading the backlog, I guess :P
2014-03-10T02:26:06 < Bird|ghosted> masa ^^
2014-03-10T02:32:15 < masa> you mean don't set the . = something; for input sections, but create separate sections for stuff and assign stuff to those sections?
2014-03-10T02:32:44 < masa> aka have separate sections, don't set the address inside one for different stuff?
2014-03-10T02:34:38 < gxti> i think when he said 'ISR vectors' he thought you/we were talking about the function body itself, which we were not
2014-03-10T02:34:53 < gxti> obviously it doesn't matter where the function body is
2014-03-10T02:35:19 < Bird|ghosted> gxti: the vector table as a whole should be pointed to the correct place
2014-03-10T02:35:33 < Bird|ghosted> you don't set start addresses for individual vectors :P
2014-03-10T02:35:46 < gxti> normally no, but he specifically asked about it
2014-03-10T02:37:34 < masa> speaking about interrupts, what do I have to do to enable interrupts? I'm learning the timers atm, and I have enabled the timer interrupt, but I'm guessing I have to enable some global or NVIC stuff before they get triggered and executed?

2014-03-10T02:49:55 < masa> I set the bit in the NVIC_ISER1 register, and it seems that it got triggered

2014-03-10T02:50:31 < masa> but I haven't enabled them globally, where is that bit located?
2014-03-10T02:51:13 < Bird|ghosted> masa: use the __enable_irq() CMSIS-intrinsic

2014-03-10T03:14:02 < Bird|ghosted> my code?
2014-03-10T03:14:15 < Bird|ghosted> or masa's code?
2014-03-10T03:14:57 < masa> uh, got it, seems that I have to clear the interrupt flag bit from the timer SR register manually. Now my led is blinking nicely once per second :p
2014-03-10T03:15:07 < Bird|ghosted> aaah
2014-03-10T03:15:41 < masa> and yeah, I'm not using any libraries or CMSIS atm, I'm, trying to learn the registers and bits and how stuff works on these chips
2014-03-10T03:16:19 < masa> so I'm just creating the register #define stuff and writing stuff to them manually
2014-03-10T03:16:21 < Bird|ghosted> masa: o.O why?
2014-03-10T03:16:35 < masa> because I want to? :p
2014-03-10T03:16:49 < Bird|ghosted> in general, you at least want to use a premade set of defines
2014-03-10T03:17:04 < masa> much easier to debug stuff if you actually understand how it is supposed to work
2014-03-10T03:17:38 < Bird|ghosted> also: for *most* peripherals, the driver libraries (locm3, stdperiph, ...) are thin helper wrappers around raw register frobbing
2014-03-10T03:17:57 < masa> I might switch to libopencm3 at some point, but still, I want to learn every bit and register I need to set in order for stuff to work
2014-03-10T03:19:17 < masa> I'm not after quick copy-paste led blinkers, I want to learn how the chip works and what needs to be set up and how to do X
2014-03-10T03:19:58 < masa> but at least I got my LED blinking now... :D
2014-03-10T03:20:10 < masa> with a timer IRQ even
2014-03-10T03:20:16 < gxti> yay.
2014-03-10T03:20:31 < masa> yep, yay
2014-03-10T03:20:54  * Bird|ghosted pokes gxti with his bitbanger (outputs 0x10/0x04/0x84 instead of the 0x20 it should, btw)

2014-03-10T12:18:54 < madisk> i've spent 15 minutes on the site and i still haven't found the link to their development tools
2014-03-10T12:19:05 < dongs> thats easy
2014-03-10T12:19:08 < dongs> there arent any.
2014-03-10T12:19:22 < madisk> their site is so shitty that if you search for STM32 chips on google, the first result is alldatasheet.com
2014-03-10T12:19:33 < madisk> there aren't any ?
2014-03-10T12:19:47 < madisk> even google can't parse st.com
2014-03-10T12:19:54 < jpa-> wasn't there some discovery board that was NRND, not the processor itself?
2014-03-10T12:20:17 < jpa-> madisk: development tools come from third-party, there aren't any ST specific tools
2014-03-10T12:20:35 < madisk> jpa-: ok. so its gcc all the way ?
2014-03-10T12:20:52 < jpa-> you can use gcc, or IAR, or keil, or whatever
2014-03-10T12:21:20 < qyx_> you can write binary directly
2014-03-10T12:21:29 < qyx_> always an option
2014-03-10T12:21:31 < jpa-> you can use butterflies if you want
2014-03-10T12:21:40 < madisk> there should be a ST chip flasher at the very least i hope
2014-03-10T12:21:56 < jpa-> sure, there is some st-link utility that works with the discovery boards
2014-03-10T12:22:32 < jpa-> though you probably want a debugger anyway, and most debugging software can program the device also
2014-03-10T12:22:36 < jpa-> e.g. openocd
2014-03-10T12:23:23 < madisk> what do you recommend on windows ?
2014-03-10T12:23:38 < PaulFertser> OpenOCD works fine even on windows.
2014-03-10T12:24:28 < jpa-> just have to install the libusb drivers instead of whatever comes by default
2014-03-10T12:27:00 < dongs> good luck.
2014-03-10T12:27:09 < dongs> install libuusb on windows, format pc next day
2014-03-10T12:27:14 < dongs> thats opensores for  you
2014-03-10T12:27:26 < madisk> dongs: what do you use ?
2014-03-10T12:27:45 < jpa-> have windows on pc, format pc next day.. that is sound advice in any case
2014-03-10T12:28:01 < PaulFertser> jpa-: not libusb, WinUSB.
2014-03-10T12:28:18 < jpa-> hm, there is a difference? :)
2014-03-10T12:28:28 < PaulFertser> dongs: no, libusb-win32 is no longer recommended for anything. The official WinUSB drivers are to be installed, it's trivial and harmless with Zadig installer.
2014-03-10T12:28:50 < dongs> bwahah
2014-03-10T12:28:51 < dongs> "harmless"
2014-03-10T12:28:52 < PaulFertser> jpa-: plenty, yes. libusb-win32 do not support libusb-1.0 api and they're also sometimes problematic as dongs noted.
2014-03-10T12:28:58 < PaulFertser> dongs: _official_ ms driver.
2014-03-10T12:28:59 < dongs> i'm fucking sorry, but "zadig" is anything but harmless.
2014-03-10T12:29:11 < dongs> i will never use anything that wants "zadig" to install shit
2014-03-10T12:29:12 < PaulFertser> dongs: have you seen any issue with zadig ever? Please share.
2014-03-10T12:29:15 < dongs> yes.
2014-03-10T12:29:23 < jpa-> PaulFertser: ah, yeah.. well i didn't remember that the current "recommended" windows version of libusb goes by different name
2014-03-10T12:29:27 < dongs> it avoids having to properly sign drivers with verisign cert
2014-03-10T12:29:29 < PaulFertser> dongs: install winusb yourself, without zadig then. You're not forced to use it.
2014-03-10T12:29:31 < dongs> which is bad bad bad bad bad bad .
2014-03-10T12:29:33 < dongs> I know.
2014-03-10T12:29:47 < dongs> the one thing that "needed" zadig, I ended up extracing the inf, signing it, and installing
2014-03-10T12:29:58 < PaulFertser> jpa-: libusb-1.0 can work with WinUSB or libusbK windows kernel drivers. libusb-win32 is problematic.
2014-03-10T12:30:20 < PaulFertser> dongs: yes, because you can sign yourself as you have certificate etc. Most windows users are better off with zadig.
2014-03-10T12:30:33 < PaulFertser> dongs: WinUSB itself is not problematic, is it?
2014-03-10T12:30:35 < dongs> PaulFertser: the problem is how its done.
2014-03-10T12:30:44 < dongs> zadig creates local certificates and bypasses signing.
2014-03-10T12:31:33 < PaulFertser> dongs: yep, but a powerful user like you can just install winusb however you want, zadig is not mandatory.
2014-03-10T12:31:41 < RaYmAn> that seems..bizarre, at least pre-windows 8...Infs for winusb doesn't have to be signed at all pre-win8
2014-03-10T12:32:08 < dongs> yea microsoft finalyl smarted up
2014-03-10T12:32:14 < dongs> now if there's no .cat it odesnt install
2014-03-10T12:32:20 < dongs> regardless if driver itself (sys/dll) is signed or not
2014-03-10T12:32:23 < PaulFertser> lol
2014-03-10T12:32:27 < dongs> weeding out all this opensores shit
2014-03-10T12:33:02 < RaYmAn> it's not exactly hard or expensive to get a valid code signing cert (does the cat have to be signed iwth a kernel mode certificate or just regular?)
2014-03-10T12:34:00 < dongs> kernel
2014-03-10T12:34:07 < dongs> so no tucows sorry
2014-03-10T12:34:09 < PaulFertser> To sum up: using OpenOCD is not problematic even on Windows. Just install the official ms WinUSB driver however you like it, and that's about it.
2014-03-10T12:34:24 < dongs> but we're back to the same question
2014-03-10T12:34:30 < dongs> why the fuck would nayone WANT to use openocd on windows
2014-03-10T12:34:35 < dongs> there's st-link / st-util orwahtever
2014-03-10T12:34:43 < dongs> and there's always jlink w/gdb server if youre into opensores
2014-03-10T12:34:57 < dongs> there is zero reason to have openocd, it barely functions on luinix, who wants it on windows??
2014-03-10T12:34:59 < PaulFertser> Does that stlink always work fine for debugging?
2014-03-10T12:35:01 < jpa-> st-link utility does no debugging
2014-03-10T12:35:17 < dongs> jpa, then use any IDE that suports stlink, done?
2014-03-10T12:35:23 < PaulFertser> dongs: jlink is additional hardware, we're talking about a person who just bought a disco board.
2014-03-10T12:35:30 < jpa-> dongs: yes, done, if you like IDEs :)
2014-03-10T12:35:48 < dongs> then coocox, and/or eclipse, 32k keil, demo iar, demo truestudio, demo wahtever teh fuck else
2014-03-10T12:35:53 < PaulFertser> dongs: openocd functions just fine on every supported platform, GNU/Linux, OS X, windows, *bsd included.
2014-03-10T12:36:21 < PaulFertser> dongs: if you know of any bugs of openocd please report, and I'll add them to the todo list/bugtracker/wherever appropriate.
2014-03-10T12:36:31 < PaulFertser> dongs: if it segfaults I'll investigate it right atm.
2014-03-10T12:36:48 < PaulFertser> dongs: if you have nothing to back up your words, then please refrain from unfounded accusations.
2014-03-10T12:38:06 < dongs> PaulFertser: some people (namely those used to opensource hardware/softawre) have fairly low expectations of "functions"
2014-03-10T12:38:28 < PaulFertser> dongs: then please report a missing feature?
2014-03-10T12:38:57 < madisk> so eclipse plus stlinkv2 should be a complete debugging and programming environment ?
2014-03-10T12:39:08 < dongs> you should use coocox
2014-03-10T12:39:16 < dongs> since they have whatever shit is needed to talk to stlink to debug
2014-03-10T12:39:16 < madisk> and eclipse+OpenOCD+WinUSB is another alternative ?
2014-03-10T12:39:19 < dongs> i dont think raw eclipse has that
2014-03-10T12:39:32 < madisk> coo cocks eh?
2014-03-10T12:39:36 < dongs> yeah,.
2014-03-10T12:39:39 < dongs> only reason to like it
2014-03-10T12:39:49 < PaulFertser> madisk: when you install official stlink drivers, it's already winusb, so you do not need to bother about that part.
2014-03-10T12:39:59 < madisk> ok
2014-03-10T12:40:12 < PaulFertser> madisk: eclipse + their hardware debugging plugin, yes.
2014-03-10T12:40:24 < madisk> what hardware debugging plugin ?
2014-03-10T12:40:38 < dongs> the thing that presents stlink to eclipse as debugger
2014-03-10T12:40:42 < madisk> coocox.org dns timeout ?
2014-03-10T12:40:53 < dongs> http://www.coocox.org/index.html works here
2014-03-10T12:40:56 < PaulFertser> "GDB Hardware Debugging Plugin"
2014-03-10T12:41:15 < jpa-> PaulFertser: oh, it is? so i was messing with zadig for no reason?
2014-03-10T12:41:17 < PaulFertser> dongs: btw, do you like using different IDEs for different targets?
2014-03-10T12:41:27 < dongs> PaulFertser: no, all the targets I need work in keil
2014-03-10T12:41:29 < PaulFertser> jpa-: iirc, yes, stlink drivers are compatible.
2014-03-10T12:41:36 < jpa-> nice
2014-03-10T12:42:52 < PaulFertser> jpa-: I've written in README.Windows that "ST-LINKv2" vendor software installs appropriate driver on its own, and nobody complained, so that must be true :)
2014-03-10T12:44:43 < madisk> dongs: you use Keil and you recomment CooCox ?
2014-03-10T12:45:05 < dongs> madisk: for freetard shit, yes
2014-03-10T12:45:13 < dongs> unless you don't plan to run out of 32k keil demo limit
2014-03-10T12:45:42 < madisk> keil has its own compiler or they use gcc ?
2014-03-10T12:46:30 < PaulFertser> Own
2014-03-10T12:47:40 < dongs> of course its own.
2014-03-10T12:47:40 < dongs> and it rapes gcc 100%
2014-03-10T12:47:40 < dongs> armcc
2014-03-10T12:47:40 < PaulFertser> And dongs thinks it generates much better code than gcc.
2014-03-10T12:47:40 < PaulFertser> Though there's not any well-known test that would prove that point.
2014-03-10T12:47:40 < PaulFertser> GCC is quite adequate for STM32s and other ARMs.
2014-03-10T12:47:40 < Lux> the generated hex size is certainly smaller

2014-03-10T12:47:47 < PaulFertser> Lux: if you have a reasonably sized testcase for me to try, I'd be willing to compare.
2014-03-10T12:48:03 < madisk> smaller machine code sort of implies faster
2014-03-10T12:48:07 < PaulFertser> Lux: because I know some people do not use gcc in the best possible way when they want to optimise for size.
2014-03-10T12:48:23 < PaulFertser> madisk: unless you count loop unrolling, inlining etc.
2014-03-10T12:48:24 < dongs> PaulFertser: my flying shit compiles to ~58k with keil and 70k+ with gccturd.
2014-03-10T12:48:32 < madisk> PaulFertser: true
2014-03-10T12:48:40 < Lux> yep that's the testcase I had in mind
2014-03-10T12:49:06 < madisk> years ago gcc used to generate broken code if you turned on -O2 or something like that. is that still a concern ?
2014-03-10T12:49:14 < PaulFertser> dongs: please link me to the repo, I'll try it when I have time, it's really interesting in fact. Preferrably with the generated map file for your keil.

2014-03-10T12:52:42 < madisk> dongs: i give a shit
2014-03-10T12:52:47 < dongs> you should
2014-03-10T12:52:55 < madisk> I'll be using Windows XP in the year 2080
2014-03-10T12:53:17 < jpa-> dongs: well, conclusion can be either "gcc is ok" or "gcc needs improvement" ;)
2014-03-10T12:53:17 < madisk> I'll probably take the Windows XP box off the internet this year though
2014-03-10T12:53:18 < dongs> i doubt that
2014-03-10T12:53:49 < madisk> no more internet for Windows XP. Microsoft has been a bad boy.

2014-03-10T16:22:10 < dongs> thin fucking connector and giant fat plug on the end

2014-03-10T16:23:03 < dongs> horrible
2014-03-10T16:23:16 < dongs> most people seem to be using same mold as USB-A
2014-03-10T16:23:21 < dongs> for the micro shit
2014-03-10T16:23:24 < dongs> so its really fat and ugly
2014-03-10T16:23:45 < zyp> heh
2014-03-10T16:23:59 < dongs> http://p.globalsources.com/IMAGES/PDT/B1046892069/USB-Data-Transfer-Cable.jpg
2014-03-10T16:24:00 < dongs> haha
2014-03-10T16:24:06 < dongs> this one is EVEN BIGGER
2014-03-10T16:24:45 < Abhishek_> a new meaning to "fat" connectors :P
2014-03-10T16:24:46 < zyp> so, what's the problem with that?
2014-03-10T16:26:20 < zyp> obviously the point of microusb is that the device with the socket can be thin, not the molding on the plug
2014-03-10T16:27:01 < dongs> ...
2014-03-10T16:27:35 < zyp> it's so they can stuff usb3 in your phone while keeping it as thin as it is
2014-03-10T16:27:51 < BrainDamage> that's still rather large on one dimension tough
2014-03-10T16:27:52 < zyp> and if you don't like it, you can still plug in a usb2 cable
2014-03-10T16:28:18 < BrainDamage> I'd rather have only usb3 and have a translator chip in the cable
2014-03-10T16:28:21 < dongs> microhdmi or wahteverhas 4 lanes and still smalelr than tha
2014-03-10T16:29:26 < dongs> 2.0 working is kinda a relief
2014-03-10T16:29:34 < dongs> at least i can use a less fucktarded looking cable
2014-03-10T16:30:00 < dongs> i got my usb3/gigE dongle thingy
2014-03-10T16:30:06 < dongs> came with a huge fat 3.0micro>A cable
2014-03-10T16:30:36 < dongs> http://i.imgur.com/CeUpRkZ.jpg
2014-03-10T16:31:20 < dongs> surprising they bothered with PTC
2014-03-10T16:31:24 < dongs> that thing cost liek $15 or somethign
2014-03-10T16:33:04 < zyp> I also have a usb3 hub here with micro as input, haven't had any problems with it
2014-03-10T16:33:19 < dongs> sure, its not a "problem"
2014-03-10T16:33:26 < dongs> other than the cable is like 5mm dia
2014-03-10T16:33:40 < dongs> and the plug is so fat, it lifts the hub thingy off the desk
2014-03-10T16:33:42 < zyp> true, that's annoying
2014-03-10T16:34:12 < Abhishek_> why so many 4R7 inductors in there?
2014-03-10T16:34:14 < zyp> I have hdmi cables here that are thinner than any usb3 cable I've seen
2014-03-10T16:34:25 < dongs> heh
2014-03-10T16:34:38 < zyp> Abhishek_, multiple voltage rails I'd guess
2014-03-10T16:35:48 < zyp> maybe one for ethernet, one for the hub and one for the vbus outputs
2014-03-10T16:35:52 < dongs> http://www.asix.com.tw/products.php?op=pItemdetail&PItemID=131;71;112 and http://www.techcodesemi.com/cn/products_info.asp?pid=26 and http://shop.via-labs.com/VL811+%20KGH%20Release%20Note.pdf
2014-03-10T16:36:03 < dongs> no, vbus better be direct from power brick
2014-03-10T16:38:11 < zyp> assuming that you have a power brick connected and aren't just running from bus power
2014-03-10T16:38:28 < dongs> right, but why would you need a dc/dc in that case anyway.
2014-03-10T16:38:40 < dongs> i havent plugged in brick yet.
2014-03-10T16:38:43 < dongs> its running off bus power.
2014-03-10T16:39:22 < zyp> delivering 5V out regardless of loss on the input?
2014-03-10T16:39:39 < dongs> not with http://www.techcodesemi.com/cn/products_info.asp?pid=26
2014-03-10T16:39:53 < dongs> its just a stepdown
2014-03-10T16:40:01 < zyp> hmm, true
2014-03-10T16:40:18 < zyp> dunno then
2014-03-10T16:40:43 < zyp> two rails for one chip and one for the other?
2014-03-10T16:40:56 < dongs> that Q1 in top right looks liek its interrupting VBUS from brick into the rest of the system
2014-03-10T16:41:07 < dongs> fairly fat trace coming from the jack
2014-03-10T16:42:17 < dongs> zyp, while youre here.
2014-03-10T16:42:24 < dongs> any way to drag component + keep traces?
2014-03-10T16:43:00 < zyp> use drag instead of move?
2014-03-10T16:43:28 < dongs> which is?
2014-03-10T16:43:47 < zyp> hit m to bring up the move menu, there you have both move and drag
2014-03-10T16:43:58 < zyp> when you just grab a component and pull it, you default to move
2014-03-10T16:44:45 < zyp> I don't remember if this works in pcb editor, but «drag» is how you move shit in schematic editor while keeping it connected at least
2014-03-10T16:44:54 < zyp> I would expect it to do the same in pcb editor
2014-03-10T16:45:11 < dongs> schematic had an option

2014-03-10T16:52:21 < dongs> still huge
2014-03-10T16:52:28 < zyp> you have a preferred size in rules
2014-03-10T16:52:44 < zyp> I tend to set preferred size same as minimum size
2014-03-10T16:52:52 < gxti> i've never seen the preferred size do much of anything
2014-03-10T16:53:29 < dongs> i set maximum to 50 ... a nd thats waht it makes
2014-03-10T16:53:35 < dongs> yea preferred doesnt seem to do shit
2014-03-10T16:53:42 < dongs> while preferred is 18
2014-03-10T16:53:56 < zyp> did you also set minimum? :p
2014-03-10T16:54:00 < gxti> usually it remembers what i want if i tab while placing, although it's not shared between placement from switching layers vs. manual place
2014-03-10T16:54:05 < dongs> zyp: sure
2014-03-10T16:54:12 < dongs> min: 18, max 50, preferred 198
2014-03-10T16:54:13 < dongs> er 18
2014-03-10T16:54:20 < dongs> and 10/16/10 for via hole size
2014-03-10T16:54:36 < zyp> hmm, ok, I don't tend to have problems with it
2014-03-10T16:54:41 < dongs> gxti: manual placement works
2014-03-10T16:54:52 < dongs> its the swithcing layers auto-vias thatget made giant

2014-03-10T16:56:10 < gxti> try tabbing before you switch layers?
2014-03-10T16:56:15  * gxti shrugs

2014-03-10T16:58:06 < dongs> tabbing works
2014-03-10T16:58:11 < dongs> but if i set via rules back to max 50
2014-03-10T16:58:14 < dongs> it ignores what i type
2014-03-10T16:58:18 < dongs> and makes them fat anyway.

2014-03-10T20:12:16 < qyx_> is it just dithering?
2014-03-10T20:13:06 < jpa-> my eink stuff doesn't do grayscale, but it is done by aborting the color change midway through
2014-03-10T20:13:23 < jpa-> internet says that the timing in that case would be quite temperature dependent

2014-03-10T22:23:29 < philpem> Fun little gotcha for anyone playing with the PWM module - when you enable PWM, it glitches high until the first counter load (!). Caught me out when I tried to use PWM to run a WS2812...  see http://tinyurl.com/p6dq4jv

2014-03-10T22:33:13 < philpem> FWIW, I put together mktoolchain before the ARM tools repo was a thing, now it's useful again because the ARM tools aren't available for Ubuntu 13.10...
2014-03-10T22:33:28 < philpem> You want the WS281x code? Sure. Just give me a moment to fix it up.
2014-03-10T22:35:03 < philpem> It's based on this: http://eliaselectronics.com/driving-a-ws2812-rgb-led-with-an-stm32/ but I've rewritten huge chunks of it in the spirit of DRY and portability.
2014-03-10T22:36:37 < philpem> I need to check the timings actually -- it's been tested with a WS2811B (soic chip) which is a bit more fussy than the standard 281x / 281xS

2014-03-11T00:02:29 < HD_Mouse> is it possible to use a DMA channel with two peripherals at once?
2014-03-11T00:03:21 < HD_Mouse> as in i want ot use USART3_Tx and SPI1_Rx at the same time, but they're both on the same DMA1 channel
2014-03-11T00:05:00 < effractur> you cant relocate then to a different pin?

2014-03-11T01:14:32  * philpem curses at the STM32 PWM controller...
2014-03-11T01:15:22 < TheSeven> philpem: you mean these feature-bloated timers?
2014-03-11T01:15:29 < philpem> yeah, that thing :P
2014-03-11T01:15:41 < tp> philpem:  handy STM toolchain, thanks for sharing
2014-03-11T01:15:56 < philpem> Somehow with 24 words in the DMA, I'm getting 25 pulses out.
2014-03-11T01:16:13 < zyp> philpem, why aren't you using preloading on the timers?
2014-03-11T01:16:17 < zyp> re: runts
2014-03-11T01:16:17 < philpem> Bonus, if the first word isn't 0x00, I get a stray pulse at the beginning too
2014-03-11T01:16:33 < philpem> preloading how? haven't seen that in the datasheet
2014-03-11T01:16:54 < zyp> then you clearly have to read the reference manual better
2014-03-11T01:17:35 < zyp> both the reload register and the compare channel registers have a preload functionality which when enabled makes any changes pend until the next timer update
2014-03-11T01:18:12 < karlp> including pretty timing diagrams showing how to get exactly what you want :)
2014-03-11T01:18:23 < philpem> these aren't being auto-reloaded

2014-03-11T01:19:14 < philpem> a chunk of code takes 24 bits in the form of three bytes, splits that out into bits then converts it into PWM values. a little like Dallas's 1-Wire bus, if you need an analogy.
2014-03-11T01:19:22 < philpem> but this is running WS2811 LEDs
2014-03-11T01:20:15 < TheSeven> so, to summarize, what you need is a fixed frequency PWM, with the duty cycle of individual pulses reflecting the bits that you want to send
2014-03-11T01:20:20 < philpem> yep
2014-03-11T01:22:47 < englishman> Haha I dealt with that too
2014-03-11T01:22:51 < zyp> philpem, I know how it works, I wrote a driver for it myself a couple of weeks ago
2014-03-11T01:23:11 < zyp> enabling preload on the compare channel you're using will solve the problem
2014-03-11T01:23:14 < englishman> DMA -> timer
2014-03-11T01:23:29 < englishman> Hmm? Will check that out, thanks
2014-03-11T01:26:30 < philpem> http://eliaselectronics.com/driving-a-ws2812-rgb-led-with-an-stm32/ is the original code
2014-03-11T01:26:36  * TheSeven wonders how much circuitry you'd need to just convert an SPI output to such a signal
2014-03-11T01:26:37 < philpem> or rather https://github.com/Torrentula/STM32F1-workarea/tree/master/Project/WS2812
2014-03-11T01:27:14 < philpem> this is my variant -- https://bitbucket.org/philpem/stm32f4_ws2811

2014-03-11T01:36:40 < TheSeven> philpem: how picky are those about the actual pulse width?
2014-03-11T01:36:42 < zyp> http://paste.jvnv.net/view/jmV9y <- here's mine, using TIM4_CH3 on an F3
2014-03-11T01:37:19 < zyp> preload is controlled by OC3PE which is bit 3 in TIM4_CCMR2
2014-03-11T01:37:20 -!- amstan [~alex@aichallenge/admin/amstan] has joined ##stm32
2014-03-11T01:37:48 < philpem> TheSeven, fairly picky. someone did a timing analysis on them -- http://cpldcpu.wordpress.com/2014/01/14/light_ws2812-library-v2-0-part-i-understanding-the-ws2812/
2014-03-11T01:38:13 < zyp> http://bin.jvnv.net/f/vw4I3.JPG <- and here's the pattern being produced by that code
2014-03-11T01:38:49 < TheSeven> so what do they do if the pulse is e.g. a bit smaller than the 0 width, or a bit bigger than the 1 width?
2014-03-11T01:39:10 < zyp> that is undefined
2014-03-11T01:39:34 < philpem> usually anything from ~50ns up to ~800us pos width is clocked in as a 0
2014-03-11T01:39:42 < TheSeven> I can't quite believe that they only have about 10% tolerance on those timings
2014-03-11T01:39:44 < philpem> in my experience anyway
2014-03-11T01:40:32 < TheSeven> philpem: at 400 or 800 khz mode?
2014-03-11T01:40:43 < zyp> TheSeven, according to the datasheet, tolerance is ±12%
2014-03-11T01:42:15 < TheSeven> anyway, we can even get close enough with SPI
2014-03-11T01:42:32 < zyp> TheSeven, or even a uart
2014-03-11T01:42:56 < philpem> TheSeven, 800kHz
2014-03-11T01:43:46 < TheSeven> philpem: so what about configuring an SPI for 800kHz and then sending 0xc0 for a 0 and 0xf0 for a 1, through DMA?
2014-03-11T01:44:06 < philpem> might work
2014-03-11T01:44:13 < philpem> haha! almost there.
2014-03-11T01:44:19 < zyp> TheSeven, would have to be 8*800kHz
2014-03-11T01:44:29 < TheSeven> er, right
2014-03-11T01:44:31 < zyp> but otherwise it'll work
2014-03-11T01:44:45 < zyp> as mentioned, I considered using a uart like that myself
2014-03-11T01:44:55 < philpem> TIM_OC1PreloadConfig(PWM_TIMER, TIM_OCPreload_Enable); --> that gets rid of the strays, but drops a bit at the beginning :(
2014-03-11T01:45:13 < zyp> but I went with a timers since more pins are available as timer outputs
2014-03-11T01:45:19 < Fleck> any good tutorial to set up toolchain on linux and compile/upload ?
2014-03-11T01:45:47 < TheSeven> that's 312.5ns/625ns, which is spot on (ranges are 175-325ns, 525-675ns)
2014-03-11T01:46:08 < zyp> philpem, initialize the channel to either 0 or 0xffff and let it be free running, then let dma just bring in the first bit starting whenever
2014-03-11T01:46:27 < zyp> i.e. start the timer before starting dma
2014-03-11T01:47:12  * TheSeven complains about a lack of DMA channels along with unfortunate mapping for the uarts
2014-03-11T01:47:23 < zyp> there's no need for stopping the timer between updates either, it can just output pulses of length 0 until you start a new dma transfer
2014-03-11T01:47:25 < philpem> zyp, thank you, that did it! :D
2014-03-11T01:47:35 < philpem> turning on the DMA after the timer, I mean
2014-03-11T01:50:55 < philpem> 24 rising edges, perfectly timed :D

2014-03-11T02:23:39 < zyp> no problem
2014-03-11T02:25:49 < dongs> Memory usage is pretty phenomenal. 24 16-bit words for every LED, plus 42 trailing words. That's 132 bytes just for one LED...

2014-03-11T02:28:03 < dongs> neat, it has a sorta-DMP thing
2014-03-11T02:28:41 < ds2> do they work?
2014-03-11T02:29:00 < zyp> no, they're just slacking off
2014-03-11T02:29:13 < philpem> dongs: you have 24 data bits to send, then 42 zeroes to space them out (50us reset delay). each counter update is a 16bit word, so that's (24 + 42) * 2 = 132 bytes
2014-03-11T02:29:16 < Lux> yeah seems pretty neat, I'm just wondering if the gyro really only has 4° bias/hour in RL
2014-03-11T02:29:35 < zyp> philpem, you can have the dma just zero-extend 8-bit words
2014-03-11T02:29:43 < zyp> all values fits <256 anyway
2014-03-11T02:29:54 < dongs> philpem: um, you don't need memory buffer for 42 zeros tho.
2014-03-11T02:30:11 < zyp> and you just need to send one zero and leave it at zero
2014-03-11T02:30:34 < dongs> i remember i only needed 24 bytes
2014-03-11T02:30:37 < dongs> for DMA on TIMx
2014-03-11T02:30:42 < philpem> yeah, it's hardly optimal code
2014-03-11T02:30:53 < zyp> I'm planning to go with a 25-byte buffer
2014-03-11T02:31:19 < zyp> 24 for data and one either 0 or 0xff for the end
2014-03-11T02:31:36 < zyp> and then just use the dma end interrupt to fill the buffer with another rgb value
2014-03-11T02:31:43 < philpem> zero-extend doesn't seem to work though, unless I've misunderstood something

2014-03-11T03:24:46 < zyp> that thing is a led coupled to a photodiode which then drives a transistor stage output

2014-03-11T09:50:50 < dongs> heh
2014-03-11T09:50:59 < qyx_> i assumed that because you are looking for flat cells
2014-03-11T09:55:28 < qyx_> as was said you would need balancing also for the 7.4V one
2014-03-11T09:55:43 < qyx_> so it is only matter of exchanging one 3pin connector for two 2pin
2014-03-11T09:56:06 < qyx_> and two cells with "single" two-cell battery
2014-03-11T09:57:58 < qyx_> pos, neg and middle
2014-03-11T09:59:36 < qyx_> interesting, don't know, but in that case balancing is not possible
2014-03-11T10:00:49 < qyx_> it depends on the chemistry
2014-03-11T10:00:56 < qyx_> but they could be handling it on the internal pcb

2014-03-11T10:03:53 < dongs> i have to buy 1500 microusb shits
2014-03-11T10:04:02 < dongs> i can use htem but.. probably wont need more for a while
2014-03-11T10:08:05 < dongs> zyp, you gonna get 200 more boards made?
2014-03-11T10:08:16 < dongs> (in next month or so)
2014-03-11T10:13:50 < dongs> right
2014-03-11T10:16:18 < dongs> lipo pack
2014-03-11T10:16:25 < dongs> also expensive as shit

2014-03-11T10:16:50 < dongs> but none of these will be flat
2014-03-11T10:16:58 < dongs> i guess you can take it apart and unroll the cells
2014-03-11T10:17:00 < dongs> yes i know
2014-03-11T10:17:08 < dongs> you can take the shrink and put cells side by side.
2014-03-11T10:17:09 < dongs> careafully.
2014-03-11T10:17:36 < dongs> you said you wanted it "smaller"?
2014-03-11T10:17:45 < dongs> because that one is $70
2014-03-11T10:17:49 < dongs> and  the one i linked is $10
2014-03-11T10:17:55 < dongs> for more capacitiy
2014-03-11T10:18:23 < dongs> right
2014-03-11T10:18:28 < dongs> it most defintely isnt
2014-03-11T10:18:38 < dongs> i have teo resolder a different kinda connector on these 4S 35C lipos

2014-03-11T21:28:04 < Fleck> any good reference manual for gcc arm? Like, what is SysTick_Config() how it works etc...
2014-03-11T21:28:29 < Fleck> maybe a book
2014-03-11T21:32:17 < Steffanx> What do want to read about it? You can look at the code and see/read what it does not?
2014-03-11T21:32:42 < Steffanx> and does the periperhap lib come with the documentation that describes it?
2014-03-11T21:33:28 < Fleck> you mean gcc source?
2014-03-11T21:34:22 < Steffanx> Noo. SysTick_Config isn't part of that
2014-03-11T21:34:45 < Steffanx> is part of the CMSIS i think
2014-03-11T21:35:13 < Steffanx> which is somewhere in the standard peripheral lib download
2014-03-11T21:35:24 < Fleck> ok, some info is here: https://www.doulos.com/knowhow/arm/CMSIS/CMSIS_Doulos_Tutorial.pdf

2014-03-11T22:53:17 < synic> hrmm, yeah, I guess what I need is just a compiler setup for linux

2014-03-12T00:29:16 < Fleck> how do you understand that - external crystal is 8MHz but STM32F4-Discovery board paper says 168MHz execution performance?
2014-03-12T00:29:33 < qyx_> huh
2014-03-12T00:29:37 < qyx_> and wheres the problem?
2014-03-12T00:30:00 < Fleck> I don't understand, how, why so etc...
2014-03-12T00:30:06 < qyx_> https://en.wikipedia.org/wiki/PLL
2014-03-12T00:30:44 < qyx_> there are multiple clock dividers/multipliers which generate required clocks
2014-03-12T00:31:21 < Fleck> ahh multipliers
2014-03-12T00:33:31 < Fleck> looking at blinky led example... and dont understand: #define SYSTICK_FREQUENCY_HZ       1000 and #define BLINK_TICKS     SYSTICK_FREQUENCY_HZ/10, when I change first define - led blinks the same, tried different values, but when I change /10 to /2 - led interval changes?

2014-03-12T00:51:01 < zyp> Fleck, that should be obvious if you think about it
2014-03-12T00:51:31 < Fleck> :/
2014-03-12T00:51:38 < zyp> if you run systick at 1000 Hz and want the led blinking with 10 Hz, the number of ticks per blink is 1000 / 10
2014-03-12T00:51:59 < zyp> if you change the systick to 100 Hz, you get 100 / 10 ticks per blink
2014-03-12T00:52:11 < zyp> that's why changing systick frequency doesn't change the led pattern

2014-03-12T00:52:26 < zyp> however, changing it to 2Hz, giving 500 ticks per blink will
2014-03-12T00:52:27 < Fleck> SysTick_Config(RCC_Clocks.HCLK_Frequency/SYSTICK_FREQUENCY_HZ); << SYSTICK_FREQUENCY_HZ is also used here
2014-03-12T00:52:33 < zyp> exactly
2014-03-12T00:52:53 < Fleck> RCC_Clocks.HCLK_Frequency is what?
2014-03-12T00:53:07 < zyp> so when you change SYSTICK_FREQUENCY_HZ, you change it both places, so the end result comes out the same
2014-03-12T00:53:15 < Fleck> yep
2014-03-12T00:53:27 < zyp> HCLK_Frequency is the frequency of HCLK
2014-03-12T00:53:37 < Fleck> and how much is it?
2014-03-12T00:53:39 < zyp> HCLK is the same as SYSCLK

2014-03-12T00:53:54 < zyp> which again is the same as the input for systick
2014-03-12T00:54:05 < Fleck> 8MHz ?

2014-03-12T00:54:20 < zyp> depends on what your SYSCLK source is
2014-03-12T00:54:23 -!- R0b0t1 [~dev@unaffiliated/r0b0t1] has joined ##stm32
2014-03-12T00:54:26 < qyx_> no, 8MHz is just the freq of your crystal
2014-03-12T00:54:28 < qyx_> and thats all
2014-03-12T00:54:54 < zyp> when the chip first starts up, it's not using the crystal at all, it's running from an internal 8 MHz source
2014-03-12T00:54:59 < Fleck> how can I tell SYSCLK source ?
2014-03-12T00:55:05 < zyp> at that point, SYSCLK is 8 MHz
2014-03-12T00:55:28 < zyp> after startup, you normally enable the crystal and the PLL to make a 168 MHz clock, and then set that as your new SYSCLK
2014-03-12T00:56:01 -!- emeb [~ericb@ip68-104-219-168.ph.ph.cox.net] has joined ##stm32
2014-03-12T00:56:12 < Fleck> http://paste.opensuse.org/38381218 << this is the blinky source
2014-03-12T00:56:57 < Fleck> where I enable a crystal and PLL ?
2014-03-12T00:57:02 < zyp> as far as I can see, it's not changing SYSCLK
2014-03-12T00:57:11 < zyp> so you're probably still running at 8 MHz
2014-03-12T00:57:35 < Fleck> ok
2014-03-12T00:58:45 < zyp> http://bin.jvnv.net/f/IjXYa.png <- perhaps this will help you
2014-03-12T00:59:31 < zyp> hmm, actually, HSI is 16 MHz, not 8 MHz, I remembered it wrong
2014-03-12T01:01:20 < Fleck> so, 16MHz get divided by 1000 - that is 16Khz ?
2014-03-12T01:01:31 < zyp> no

2014-03-12T01:02:30 < zyp> that is used to configure systick to divide the input by 16000, which then gives a 1000 Hz systick
2014-03-12T01:03:45 < Fleck> right... arg for SysTick_Config()

2014-03-12T01:28:38 < Fleck> gxti: where are they? on paper the link was st.com/stm32f4-discovery but I don't find samples there
2014-03-12T01:30:02 < Fleck> The demo software as well as other software samples that allow you to discover the STM32 F4 series features are available on www.st.com/stm32f4-discovery ...
2014-03-12T01:30:11 < Steffanx> all the clock stuff is probably in some file called "system_stm32f40x.c"  or something.
2014-03-12T01:30:11 < Steffanx> all examples come with this file
2014-03-12T01:30:25 < Steffanx> ( at least i guess you're using the std peripheral lib from ST ?)

2014-03-12T07:37:14 < emeb_mac> zyp: I use a 0.1uf on each vdd and a 10uf on each supply
2014-03-12T07:37:22 < emeb_mac> seems to be enough
2014-03-12T07:37:31 < emeb_mac> (haven't had any issues)
2014-03-12T07:37:52 < zyp> "each vdd" :)
2014-03-12T07:38:29 < zyp> the FT256 has 26 of those
2014-03-12T07:38:33 < zyp> and 28 grounds
2014-03-12T07:39:38 < zyp> four per bank, four for aux and six for core voltage
2014-03-12T07:46:27 < emeb_mac> :)
2014-03-12T07:46:33 < emeb_mac> that's a lot isn't it?
2014-03-12T07:47:03 < emeb_mac> plus with BGA it's hard to locate the caps close to the pad
2014-03-12T07:47:34 < zyp> nah, I think I'm gonna put them on the bottom this time
2014-03-12T07:47:50 < emeb_mac> you should look at some of the stupid stuff that some FPGA layouts do...
2014-03-12T07:48:13 < zyp> http://bin.jvnv.net/f/ISnRs.png
2014-03-12T07:48:15 < emeb_mac> I saw one where they put all the decoupling caps in a group nearby the part
2014-03-12T07:48:53 < emeb_mac> tight layout.
2014-03-12T07:49:02 < emeb_mac> maybe use 0201 caps? :)
2014-03-12T07:49:13 < zyp> those are 0603s
2014-03-12T07:49:21 < zyp> the pads underneath the center
2014-03-12T07:49:26 < zyp> looks sane enough
2014-03-12T07:50:20 < zyp> http://bin.jvnv.net/f/2xmE7.png
2014-03-12T07:52:39 < zyp> those are 1.2V, I could probably fit a couple for 3.3V on either side around it
2014-03-12T07:52:48 < zyp> I guess 8 on 3.3V should be enough
2014-03-12T07:53:22 < ds2> hmmm?
2014-03-12T07:53:29 < ds2> 0201's fit well between BGA balls
2014-03-12T07:53:38 < emeb_mac> you have planes for vddio & vddcore?
2014-03-12T07:54:13 < zyp> core is the rectangle in the center on the bottom, vddio is on a inner plane
2014-03-12T07:54:58 < zyp> I don't see the need for a full plane for core when all the pads that go on it are located in one place
2014-03-12T07:55:30 < emeb_mac> ya
2014-03-12T07:56:40 < emeb_mac> on my 4L boards I've done core as a smaller rect inside the 3.3V plane on an inner layer
2014-03-12T07:57:16 < zyp> I could do that as well, but I don't see the point
2014-03-12T07:58:20 < zyp> I'm gonna have the decoupling on the bottom, and I'm gonna route it out on the bottom, so I'm not really saving anything by not placing the entire polygon on the bottom
2014-03-12T07:58:30 < emeb_mac> true
2014-03-12T07:58:45 < emeb_mac> maybe put some more caps around the outside on the bottom?
2014-03-12T07:59:12 < emeb_mac> since you're doing 2-sided components anyway...
2014-03-12T07:59:22 < zyp> yes, that's what I'm thinking
2014-03-12T07:59:30 < zyp> caps close to the 3.3V inputs
2014-03-12T07:59:50 < emeb_mac> yep
2014-03-12T07:59:54 < zyp> I checked the datasheet, 100qfp has four 1.2V-inputs and 8 3.3V-inputs
2014-03-12T08:00:29 < zyp> and since I assume this is more or less the same die, it shouldn't require more decoupling
2014-03-12T08:00:55 < zyp> so eight caps around the four I have will probably do just fine
2014-03-12T08:01:54 < emeb_mac> plus you're not likely to be running your IO fast enough that bounce / sag will be a big deal
2014-03-12T08:02:13 < zyp> how fast would that be? :p
2014-03-12T08:02:56 < emeb_mac> depends on how many simultaneous switching you have, plus what iostd, etc.
2014-03-12T08:03:34 < emeb_mac> but I'd be careful about running > 50MHz

2014-03-12T08:06:03 < ds2> can you DMA out the ports at that rate?
2014-03-12T08:06:15 < emeb_mac> 100MHz?
2014-03-12T08:06:19 < emeb_mac> doubt it
2014-03-12T08:06:31 < emeb_mac> what for DAC?
2014-03-12T08:06:47 < ds2> yep
2014-03-12T08:06:52 < zyp> in this case I'll be hooking the FPGA up to the FSMC
2014-03-12T08:07:47 < emeb_mac> ds2: on-chip DACs on the F4 have slow analog buffers - can't really sample faster than ~100kHz or so.
2014-03-12T08:08:22 < emeb_mac> the audio DAC on the F4 Disco only runs at audio speeds - 48kHz / 96kHz, etc
2014-03-12T08:09:07 < emeb_mac> driving an off-chip high-speed DAC thru GPIO might work tho. Could probably get fairly good speed with DMA
2014-03-12T08:09:22 < emeb_mac> but keeping up with it over long waveforms would be tough

2014-03-12T08:18:19 < ds2> Isn't 100MHz rate enough to generate an AM signal at about 50MHz?
2014-03-12T08:18:24 < ds2> 6M ham
2014-03-12T08:20:56 < emeb_mac> you'd need to run a bit higher sample rate than 100MHz to do 6M without massive distortion
2014-03-12T08:21:11 < emeb_mac> I'd run it more like 130
2014-03-12T08:21:23 < ds2> hmmm
2014-03-12T08:22:18 < emeb_mac> or, you could try using a harmonic, but that's iffy with output.

2014-03-12T08:32:03 < Jack3k3> hey so ive been working on debugging this i2s receive bullshit from my audio codec.. it seems the interrupt handler SPI3_IRQHandler is indeed triggering, and if I accumulate 1000 samples of the received data and average it, I get something around 1290 or so
2014-03-12T08:32:32 < Jack3k3> I don't know if this means anything? unfortunately changing the voltage to the codec's ADC doesn't seem to significantly affect this number though
2014-03-12T08:33:43 < emeb_mac> why not dump the raw data out and plot the waveform?
2014-03-12T08:33:50 < emeb_mac> see if it's noise or what...
2014-03-12T08:34:31 < Jack3k3> im assuming theres a relatively simple way of doing that in the debugger?
2014-03-12T08:34:33 < emeb_mac> bear in mind that if your codec has a highpass function on the input (many do) then DC voltage into it won't do much

2014-03-12T15:58:15 < dongs> My led driver is 4.5..24V in
2014-03-12T15:58:29 < dongs> while the shit they used (which I considered, but rejected) is 2.7 to 6.5V
2014-03-12T15:58:53 < dongs> so tehy're actually wasting more power, because they first drop 9-12V to 3.3V then step it back up to 40 or whatever with leddriver

2014-03-12T16:29:59 < __rob> hello
2014-03-12T16:30:26 < __rob> can anyone tell me how good the internal low speed oscillator will be for driving the RTC on a cortex m0?
2014-03-12T16:30:36 < __rob> or should I be using an external crystal ?
2014-03-12T16:32:44 < Cyric> I think you should get an external
2014-03-12T16:33:31 < Cyric> but i would wait more confirms from someone with more experience than me
2014-03-12T16:33:48 < talsit1> well, the internatl can vary quite a lot over temperature
2014-03-12T16:33:57 < talsit1> what's the ppm on that?

2014-03-12T18:24:52 < madist> there is no virtual COM port on a discovery board right ?
2014-03-12T18:25:27 < jpa-> not built-in
2014-03-12T18:25:28 < madist> (as part of the STLink)
2014-03-12T18:25:33 < jpa-> nope
2014-03-12T18:25:34 < Rickta59> nucleo's have those
2014-03-12T18:25:46 < jpa-> though if you reprogram with black magic probe then you have it
2014-03-12T18:25:51 < Rickta59> with header pins too
2014-03-12T18:25:53 < madist> ok
2014-03-12T18:29:05 < madist> I'm trying to use a F4 discovery board to flash a VL discovery board. I've wired up the SWDIO and SWCLK correctly.
2014-03-12T18:29:24 < madist> when I run the STLink Utility to connect to target I get this error:
2014-03-12T18:29:25 < madist> Can not connect to target!
2014-03-12T18:29:25 < madist>                   Please select "Connect Under Reset" mode from Target->Settings menu and try again.
2014-03-12T18:29:32 < madist>  Internal command error
2014-03-12T18:29:45 < effractur> and holding the vl in reset?
2014-03-12T18:29:57 < madist> that has to be done manually ?
2014-03-12T18:30:21 < effractur> you van try atleast
2014-03-12T18:30:26 < madist> the VL reset pin is not brought out anywhere
2014-03-12T18:30:31 < effractur> mm
2014-03-12T18:30:41 < madist> ah C10
2014-03-12T18:30:44 < madist> will try
2014-03-12T18:31:10 < karlp> any particular reason you don't juse use the stlinkv1 on the vl discovery board?
2014-03-12T18:31:16 < karlp> it doesn't have swo, but it works just fine.
2014-03-12T18:31:32 < madist> just want to try flashing blackmagic/versaloon etc
2014-03-12T18:32:13 < GargantuaSauce> if you use oocd you can spam the reset command just before flashing and it might work
2014-03-12T18:32:14 < jpa-> ah, you are flashing the stlink controller, not the main controller
2014-03-12T18:32:21 < karlp> so are you talking about flasing the stlink or the vl example?
2014-03-12T18:32:23 < karlp> yeah, what he said.
2014-03-12T18:32:35 < jpa-> that's what I said!
2014-03-12T18:32:35 < madist> yes, the STLink controller. the F103
2014-03-12T18:32:42 < GargantuaSauce> oh
2014-03-12T18:32:53 < karlp> so who cares aboutthe vl's reset pin then?
2014-03-12T18:33:09 < karlp> "VL" means value line ==> f100, not f103
2014-03-12T18:33:11 < madist> I'm out of ideas. What are the things that could go wrong ?

2014-03-12T18:34:05 < Rickta59> you might try openocd like GargantuaSauce said and configure it with reset config none
2014-03-12T18:34:19 < madist> shouldn't STLink just work ?
2014-03-12T18:34:21 < karlp> or question whether this is something you really want to bother doing.
2014-03-12T18:34:44 < jpa-> madist: maybe your wires are wrong :)
2014-03-12T18:34:54 < madist> jpa-: checked and checked again.
2014-03-12T18:35:48 < englishman> Did you disconnect the vl chip from the stlink on the discovery?
2014-03-12T18:35:50 < englishman> So you're not trying to program two chips
2014-03-12T18:35:52 < madist> yes
2014-03-12T18:36:08 < madist> the F100 on the discovery board is disconnected
2014-03-12T18:36:13 < madist> (CN3 jumpers removed)
2014-03-12T18:36:26 < englishman> I have a vldiscovery too, which I used for St link after changing some solder jumper settings
2014-03-12T18:36:33 < jpa-> uh... you didn't wire it to *those* swdio & swclk.. you soldered the wires, right?
2014-03-12T18:36:37 < madist> yes
2014-03-12T18:36:43 < jpa-> so shouldn't matter
2014-03-12T18:36:47 < madist> wires soldered under the board on the solder bridges
2014-03-12T18:37:00 < englishman> I had to change at least two jumpers, I forget it was last year, just check all the jumpers
2014-03-12T18:37:18 < englishman> And, nRST is available on the 6pin stlink header?
2014-03-12T18:37:29 < madist> not on the VL board
2014-03-12T18:37:42 < madist> it is there on the F4 board
2014-03-12T18:37:45 < englishman> ...reslly,
2014-03-12T18:38:04 < madist> what does nRST mean ? the chip has a reset pin labeled RST.
2014-03-12T18:38:11 < englishman> ....
2014-03-12T18:38:25 < madist> what's the significance of the 'n' ? in nRST
2014-03-12T18:39:17 < englishman> Oh hmm that is different

2014-03-12T18:40:40 < madist> should i try wiring pin 7 (RST) on the F103 to the F4 Discovery board's SWD connector pin 5 (NRST) ?
2014-03-12T18:40:48 < GargantuaSauce> i believe it's equivalent to / or a horizontal bar, in denoting 'not'
2014-03-12T18:40:58 < madist> that makes sense
2014-03-12T18:41:02 < GargantuaSauce> ie pulled down = reset
2014-03-12T18:41:47 < GargantuaSauce> and that's what rst is too i think, it's just a dumb difference in notation probably

2014-03-12T18:56:47 < madist> that it says: " Internal command error

2014-03-12T18:56:53 < madist> the error is something else
2014-03-12T18:57:10 < madist> i.e. the F4 board can talk to the F103.

2014-03-12T20:19:31 < Robint91> did anyone do assym encryption on a stm32
2014-03-12T20:19:39 < Robint91> not with the crypto series?
2014-03-12T20:21:16 < qyx_> i just did a testing mesh node firmware with ecdsa auth
2014-03-12T20:21:35 < qyx_> actually never tried to run that on stm32 directly, just in simulator
2014-03-12T20:21:42 < qyx_> but it shouldn't be a problem
2014-03-12T20:22:00 < qyx_> you can use this https://github.com/polarssl/polarssl
2014-03-12T20:22:55 < Steffanx> gpl ..
2014-03-12T20:23:43 < qyx_> it wasn't a problem for this particular project
2014-03-12T20:24:12 < qyx_> there are several other alternatives
2014-03-12T20:24:47 < qyx_> i am trying to avoid only libtomcrypt, it is a bit messy

2014-03-13T03:52:46 < GargantuaSauce> perhaps running from the debugger allowed one of the interrupts to fire before part of the init code? or vice versa?

2014-03-13T04:29:38 < Bird|ghosted> dongs: sometimes you *want* a T/H connector for robustness reasons
2014-03-13T04:30:00 < dongs> of course, im just surprised it exists
2014-03-13T04:30:15 < Bird|ghosted> wonder if you could get it as a press-fit
2014-03-13T04:30:18 < Bird|ghosted> or just in solder tail
2014-03-13T04:30:47 < dongs> normal DP is smt for signal and 4 dip for mounting
2014-03-13T04:30:51 < dongs> but i still do it with reflow
2014-03-13T04:30:56 < dongs> just paste over 4 dip parts and it works fine
2014-03-13T04:31:06 < dongs> i think thats how it should be nayway
2014-03-13T04:31:52 < Bird|ghosted> Pin in Paste, basically, IOW? shouldn't be an issue as long as a) the stencil deposits enough paste and b) the connector can take the heat, which in this day and age, ought to be a given :)
2014-03-13T04:32:08 < englishman> what pin pitch
2014-03-13T04:32:17 < dongs> 0.5
2014-03-13T04:32:28 < dongs> DIP one does it by staggering 3 rows
2014-03-13T04:32:33 < dongs> to make it.. possible
2014-03-13T04:32:35 < englishman> yeah
2014-03-13T04:32:37 < englishman> not 0.1"
2014-03-13T04:32:44 < englishman> so... TIP
2014-03-13T04:32:46 < englishman> hehe
2014-03-13T04:32:49 < dongs> cant be used with arduino
2014-03-13T04:33:39 < Bird|ghosted> well, can't be used with breadboards or perfboards, either :P
2014-03-13T04:34:33 < Bird|ghosted> (while you wouldn't ever want to do things that fast on a breadboard, wirewrap on a Pad per Hole perfboard probably could be done at those speeds)
2014-03-13T04:37:50 < dongs> i heard pcie is pretty tolerant to cable lengths twisting etc

2014-03-13T07:23:54 < englishman> In digital video, the sampling rates for composite video signals are 14.3181818 MHz and 17.734475 MHz for NTSC and PAL respectively.
2014-03-13T07:24:10 < dongs> oh, pal
2014-03-13T07:24:20 < englishman>  PAL: Luminance sampling frequency of 17.734475 MHz

2014-03-13T07:24:53 < GargantuaSauce> that is an awfully precise quantity
2014-03-13T07:25:07 < jpa-> GargantuaSauce: so is 10.000000 MHz
2014-03-13T07:25:39 < jpa-> 6 decimals is a pretty normal precision for specifying crystals
2014-03-13T07:26:34 < GargantuaSauce> and the drift is what
2014-03-13T07:27:00 < jpa-> whatever is specified, one or two of the last decimals
2014-03-13T07:27:01 < GargantuaSauce> i suspect it's notably more than 0.00001%
2014-03-13T07:27:36 < jpa-> good TCXO (or just a normal crystal operated in constant temperature) is less than 10ppm
2014-03-13T07:27:48 < GargantuaSauce> huh.
2014-03-13T07:32:22 < zyp> crystals are usally 30ppm across the temperature range

2014-03-13T07:56:39 < Jack3k3> ugh this is so frustrating
2014-03-13T07:57:03 < Jack3k3> i feel like i have to disregard that it worked once because im not getting ANY more signs of it working again
2014-03-13T07:57:55 < tp> that would be silly
2014-03-13T07:58:17 < tp> cant change the past, it DID work
2014-03-13T07:58:22 < Jack3k3> i know but I mean it working has given me almost no helpful signs
2014-03-13T07:58:32 < Jack3k3> it could literally be anything
2014-03-13T07:58:50 < tp> I understand it is *frustrating*, Ive been there many times
2014-03-13T07:59:02 < tp> when Im stuck, I :-
2014-03-13T07:59:16 < tp> 1) take a break for a while, go to the movies etc
2014-03-13T07:59:38 < tp> 2) try and look at the problem differently, perhaps collect different data
2014-03-13T08:00:01 < tp> 3) write it all down, keep good notes
2014-03-13T08:00:28 < tp> and you'll eventually find the problem, which is 99.99% of the time, something you're doing
2014-03-13T08:00:48 < jpa-> sometimes it is something you're not doing :)
2014-03-13T08:01:21 < tp> sure
2014-03-13T08:01:40 < tp> there is *always* a reason, even if we can't see it at the time
2014-03-13T08:02:21 < Jack3k3> yeah although it working was after takin like a week off working on it
2014-03-13T08:02:33 < Jack3k3> figured i had that breakthrough. but nope >:o
2014-03-13T08:03:09 < tp> sometimes it hard to find, I recall once we had a flaky RTC because it was too slow by about 50nS. I studied the data on a logic analyser, and tightened the times by terminating the bus lines, worked perfectly after that
2014-03-13T08:03:27 < Jack3k3> yeah honestly i probably need a logic analyzer but i have none
2014-03-13T08:03:36 < Jack3k3> i mean i have shity usb scope analyzer but I doubt its fast enough
2014-03-13T08:03:43 < tp> often, the answer is there, we just have to see it
2014-03-13T08:04:04 < tp> and sometimes, decent test gear is needed

2014-03-13T08:07:13 < Jack3k3> not sure where the heck im gonna get access to a analyzer.... maybe i can convince the university around here to let me use one, or just sneak in their lab :p
2014-03-13T08:07:27 < zyp> what were your project again?
2014-03-13T08:10:00 < Jack3k3> for now just trying to get my audio codec chip working, a uda1380... the i2s2 TX works for playing audio but the i2s3 for RX audio from the codec's ADC is still not working
2014-03-13T08:10:11 < zyp> ah, right
2014-03-13T08:10:13 < tp> Jack3k3:  first make sure that the chip registers have what you expect by single stepping thru the code with GDB ?
2014-03-13T08:10:27 < Jack3k3> right now the SPI3 interrupt is triggering but the rx data is just 0s
2014-03-13T08:10:38 < Jack3k3> tp, ill give that a try
2014-03-13T08:10:46 < zyp> Jack3k3, can I see your code?
2014-03-13T08:10:51 < tp> do it methodically, look at EVERYTHING
2014-03-13T08:11:07 < tp> and send zyp your code :)
2014-03-13T08:11:12 < Jack3k3> sure one sec

2014-03-13T08:21:14 < Jack3k3> anyway, the important functions are UDA1380_Configuration where the gpio/i2s2 (tx) /i2s3 (rx) is setup, the main function where I enable spi2/spi3 + flags + interrupt, and the SPI3_Interrupt
2014-03-13T08:22:26 < GargantuaSauce> why enable spi2 txe interrupt if you don't define a handler?
2014-03-13T08:23:13 < Jack3k3> well i did have some code to do a while loop to wait for the txe flag to be set before sending, but i removed that

2014-03-13T08:23:22 < Jack3k3> i was just trying to do everything barebones
2014-03-13T08:23:38 < Jack3k3> just to get it working
2014-03-13T08:23:49 < GargantuaSauce> well it certainly isn't guaranteed that spi2's txe is set when spi3's rxne fires
2014-03-13T08:23:52 < zyp> where is the DMA config?
2014-03-13T08:24:12 < zyp> oh, wait, you're not using DMA at all?
2014-03-13T08:24:18 < Jack3k3> no i removed it
2014-03-13T08:25:09 < Jack3k3> i felt like there was too much extra stuff to get in the way when all i want to do is get the receiving to work
2014-03-13T08:25:27 < tylerdurden> hi
2014-03-13T08:25:29 < tylerdurden> hi can some one explain me how to avoid multiple port interrupts in stm32l152cb currently i am getting more than 300 interrupts, pardon me for silly questions....
2014-03-13T08:25:32 < zyp> fair enough
2014-03-13T08:25:52 < zyp> tylerdurden, what do you mean?
2014-03-13T08:25:56 < jpa-> tylerdurden: you mean switch bounce or something?
2014-03-13T08:26:08 < tylerdurden> yes
2014-03-13T08:26:23 < tylerdurden> for one button press i am getting more tha n 200
2014-03-13T08:26:27 < tylerdurden> interrupts
2014-03-13T08:27:04 < zyp> turn off the interrupt after the first one and wait a while before turning it on again
2014-03-13T08:27:41 < jpa-> easy way is just to handle buttons by polling instead of interrupts.. debouncing is much easier to do then
2014-03-13T08:27:52 < zyp> also true
2014-03-13T08:28:14 < zyp> interupts for buttons is mainly interesting when you want it to wake up a sleeping cpu
2014-03-13T08:28:16 < dongs> tylerdurden: add r/c to the button>?
2014-03-13T08:28:34 < jpa-> yeah, RC filter + schmitt trigger inputs is another easy way

2014-03-13T08:30:57 < jpa-> well, either hardware RC filter or this algorithm in software: on first "1", start waiting; wait until you have "0" for 50ms; then return the button press
2014-03-13T08:31:04 < zyp> depends on the application
2014-03-13T08:31:24 < jpa-> whether "wait" is done by RTOS, interrupts or busyloop depends on application
2014-03-13T08:32:33 < zyp> for my usb stuff I'm not debouncing at all, I'm just polling once per frame, and if bounce makes one of the polled values ambiguous, so be it
2014-03-13T08:33:00 < tylerdurden> currently i am sending an event in RTOS for button press and watiting for 50ms  to send another event which confirms it but i am getting 200 events in queue which overflows...

2014-03-13T10:38:09 < dongs> so how thefuck do i connect 24V to optocoupler
2014-03-13T10:39:25 < dongs> just a resistor in series?
2014-03-13T10:39:34 < jpa-> yes
2014-03-13T10:39:43 < GargantuaSauce> yeah it's just an LED after all
2014-03-13T10:39:44 < dongs> sounds easy.
2014-03-13T10:39:59 < jpa-> if you want noise resistance in case of disconnected input, also add a parallel resistor for pulldown
2014-03-13T10:40:52 < jpa-> (can also help to handle reverse input voltage if you need that, sometimes the maximum reverse voltage of optocouplers is quite small)
2014-03-13T11:04:01 < dongs> nah this shit plugs into some DB25 thing thats cant be backwards

2014-03-13T18:19:39 < madist> statistically, someone out there must have had trouble
2014-03-13T18:19:51 < karlp> I've had problems with usb3, that turned up with a stm32 usb device, but it was nothing to do with the stm32
2014-03-13T18:21:42 < dan2003> hmm, in my case, the app works on a USB2 root hub, not on a USB 3 one, the driver and wireshark both show the device ack'd a bulk OUT write, but after the first one no interrupts for the bulk OUT occur, both bulk IN and control work fine

2014-03-13T20:11:26 < vein> hey Im trying to get CAN working in stm32f4, its working in loopback mode but not on physical layer. I can see a triangular waveform on the canH pin from the transreciever
2014-03-13T20:12:17 < vein> here is my CAN code

2014-03-13T20:19:52 < Thorn> you should scope a RX pin (or both canh and canl in differential mode) to see what's actually going on

2014-03-13T20:21:42 < vein> alright, i shall try that
2014-03-13T20:22:10 -!- claude is now known as Claude
2014-03-13T20:29:24 < madist> do you need a CAN txciever or can you wire up two F4 discoverys to each other directy ?
2014-03-13T20:29:35 < madist> that should simplify debugging i guess.
2014-03-13T20:29:42 < zyp> you need a transceiver
2014-03-13T20:30:01 < zyp> canrx needs the cantx feedback
2014-03-13T20:30:12 < Thorn> obligatory appnote http://www.mikrocontroller.net/attachment/28831/siemens_AP2921.pdf
2014-03-13T20:30:36 < zyp> without the feedback, the controller will believe it loses arbitration all the time
2014-03-13T20:31:07 < vein> As i have read, transreciever is mandatory to get diffrential voltage levels
2014-03-13T20:31:13 < zyp> but you can emulate a bus with transceivers by wiring all cantx signals through an AND gate and distribute the result back into all cantx pins
2014-03-13T20:31:30 < zyp> because a CAN bus acts as a distributed AND gate
2014-03-13T20:32:01 < zyp> 1 is the idle state, and the bus state is only 1 when all senders send 1
2014-03-13T20:32:28 < madist> vein: i didn't mean a production CAN bus without txceivers, I meant for debugging.
2014-03-13T20:32:57 < zyp> I've done something like that before
2014-03-13T20:33:17 < zyp> I put a cpld as a hub between a bunch of microcontrollers to use that to emulate a CAN bus
2014-03-13T20:34:09 < vein> interesting.
2014-03-13T20:34:11 < Thorn> 1 diode per node is enough
2014-03-13T20:34:17 < Thorn> see the appnote

2014-03-14T03:49:40 < madist> error in the F4 Discovery board docs ? the schematic shows pin 2 to ground through a 10k resistor and pin 3 open. the board i have has 2 10k resistors, both pin 2 and 3 to ground.
2014-03-14T03:49:54 < madist> what is "Board Ident" anyway ?
2014-03-14T03:51:06 < GargantuaSauce_> they do a few different processes and materials i think
2014-03-14T03:51:26 < GargantuaSauce_> shapeways is just the first one that came to mind. there are a bunch of american ones and there's probably one cheaper than shapeways

2014-03-14T04:26:46 < zyp> emeb_mac, by the way, do you have any opinion of lattice? someone were talking about the iCE40 chips being nice for small stuff
2014-03-14T04:27:04 < emeb_mac> never used them
2014-03-14T04:27:19 < emeb_mac> but they do have some much smaller parts, and lower power too
2014-03-14T04:27:40 < zyp> yeah
2014-03-14T04:27:57 < zyp> there's even a qfn32 part, in addition to all the insane pitch bga ones
2014-03-14T04:28:18 < emeb_mac> iirc they're flash-based too, so faster startup & less extra hw
2014-03-14T04:28:40 < zyp> so it seems like something that'd compete pretty well with a cpld for low complexity stuff

2014-03-14T04:29:52 < zyp> and I'm still a bit tempted to play around with smartfusion
2014-03-14T04:30:19 < zyp> the availability of an AHB master port so you can do custom DMA sounds tempting
2014-03-14T04:30:21 < emeb_mac> never been too impressed with the analog array stuff
2014-03-14T04:30:38 < zyp> analog array?
2014-03-14T04:30:52 < zyp> ah, right
2014-03-14T04:31:00 < zyp> I haven't thought about that at all
2014-03-14T04:31:36 < emeb_mac> the analog stuff usually ends up being pretty lame
2014-03-14T04:31:44 < emeb_mac> low bandwidth, noisy, etc
2014-03-14T04:31:50 < zyp> it's the close integration of fpga+mcu that I find interesting
2014-03-14T04:31:59 < emeb_mac> yes
2014-03-14T04:32:16 < zyp> which you'd otherwise only get using softcores
2014-03-14T04:32:22 < emeb_mac> at a somewhat smaller scale than the big-ass SoC systems like Cyc V and Zynq
2014-03-14T04:32:31 < zyp> exactly
2014-03-14T04:32:56 < emeb_mac> getting those guys up and running is a major PITA
2014-03-14T04:33:16 < emeb_mac> basically like configuring a full-up PC-equivalent
2014-03-14T04:34:24 < zyp> cortex-m1 could be interesting too, if that were easily available
2014-03-14T04:34:28 < zyp> but it doesn't seem to be
2014-03-14T04:34:54 < zyp> last time I looked around, I only found some dead links to an altera evalboard which included cortex-m1, IIRC
2014-03-14T04:34:58 < emeb_mac> not w/o $$

2014-03-14T08:15:44  * emeb_mac shakes cane
2014-03-14T08:15:52 < ds2> it all started out as what suppose to be a simple 50MHz square wave
2014-03-14T08:16:24  * emeb_mac chuckles
2014-03-14T08:16:40 < ds2> to be fair, I am using a hantek scope ;)
2014-03-14T08:17:09 < emeb_mac> 50MHz square wave needs harmonics > 350MHz to look "square"
2014-03-14T08:17:22 < ds2> I know that
2014-03-14T08:17:31 < ds2> it is the undershoot/overshoot that is bugging me
2014-03-14T08:17:36 < ds2> 3.3V supply
2014-03-14T08:17:49 < emeb_mac> under/over could be probe compensation
2014-03-14T08:17:53 < emeb_mac> or bad grounding
2014-03-14T08:17:54 < ds2> but I see about -0.4V to 3.8V
2014-03-14T08:18:12 < ds2> grounding is horrible
2014-03-14T08:18:22 < emeb_mac> or trace inductance, etc etc
2014-03-14T08:18:49 < ds2> the ground point is probally 3-4 inches away
2014-03-14T08:19:16 < emeb_mac> ouch
2014-03-14T08:19:43 < madist> i'm thinking of laying a sheet of aluminum foil on the underside of my desk and grounding that.
2014-03-14T08:19:54 < ds2> emeb_mac: screwing with the BBB and using the clipleads of the scope probe so...
2014-03-14T08:20:11 < ds2> no F4 discoveries on me :(
2014-03-14T08:21:00 < emeb_mac> ds2: yeah - hard to get great grounds on the BBB headers
2014-03-14T08:21:36 < emeb_mac> how boring

2014-03-14T08:22:25 < tp> <madist> a sheet of aluminum foil grounded, works wonders with 'mains hum' etc
2014-03-14T08:22:32 < ds2> heh... I learned about the 50ohm thing a few weeks ago
2014-03-14T08:22:48 < ds2> huge amounts of ringing on a function generator circuit

2014-03-14T08:23:51 < ds2> what annoys me about tek scopes is the probe pin breaks easily

2014-03-14T09:24:35 < madist> if you flash the STLinkv2 firmware on a VL Discovery board, is it straightforward to use or do you need modify the circuit ?
2014-03-14T09:24:48 < dongs> what is 'stlink firmware'?
2014-03-14T09:25:11 < madist> the code that runs on the STLink dongle
2014-03-14T09:25:18 < tp> madist, sure, works fine
2014-03-14T09:25:27 < tp> no mods needed
2014-03-14T09:25:34 < madist> i tried it, and there are 2 problems
2014-03-14T09:25:43 < tp> oh ?
2014-03-14T09:25:43 < madist> first, it shows up as JTAG+SWIM Debugger
2014-03-14T09:25:45 < dongs> madist: where do you "get" it?
2014-03-14T09:25:48 < madist> instead of JTAG Debugger
2014-03-14T09:25:50 < dongs> i thought it was closed sores
2014-03-14T09:25:54 < madist> dongs: it is
2014-03-14T09:26:20 < madist> secondly, the circuit on the board differs
2014-03-14T09:26:26 < madist> the pin assignments are different
2014-03-14T09:26:32 < dongs> madist: so how are you flashing it
2014-03-14T09:26:34 < tp> madist what version of stlinkV2 ?
2014-03-14T09:26:49 < madist> tp: tried several versions. 15,16 and 19 I think
2014-03-14T09:26:56 < madist> dongs: using a F4 Discovery board
2014-03-14T09:27:07 < dongs> where did you get hex?

2014-03-14T09:27:35 < PaulFertser> dongs: on some russian forum, folks dumped it a year ago already.
2014-03-14T09:27:40 < tp> dongs you don't need a bootloader
2014-03-14T09:27:52 < dongs> oh, just the userspace hex
2014-03-14T09:27:54 < dongs> thats useelss.
2014-03-14T09:27:59 < dongs> i dumped that years ago
2014-03-14T09:28:02 < madist> tp: you didn't modify the circuit in any way ? there are a pair of 10k resistors on pins 2 and 3 of the STM32F103 chip on the F4 Discovery board.
2014-03-14T09:28:03 < PaulFertser> dongs: no, shit dumped
2014-03-14T09:28:11 < dongs> its aes "encrypted" in stlinkupdater.exe

2014-03-14T09:32:45 < dongs> probly version control
2014-03-14T09:32:59 < dongs> cuz pc13/14/15 are fucking useless pins
2014-03-14T09:33:03 < dongs> that cant source or sink
2014-03-14T09:33:07 < tp> I had to do a few things to the vl discovery yes
2014-03-14T09:33:08 < dongs> and don't have any useful peripheralsa on them
2014-03-14T09:33:21 < madist> tp: aha! that's what I wanted confirmation of.
2014-03-14T09:33:41 < madist> so you *do* need to modify the hardware to resemble the F4 discovery board.
2014-03-14T09:34:08 < madist> dongs: I found a doc that refered to PC13 as "Tamper detect".
2014-03-14T09:34:19 < dongs> madist: thats unrelated tho
2014-03-14T09:34:26 < tp> the SWD wired from the F4 discovery have to be soldered to the bottom on the VL discovery
2014-03-14T09:34:40 < madist> tp: that's for flashing the VL Discovery
2014-03-14T09:34:47 < madist> that part I did and it was successful
2014-03-14T09:34:48 < tp> exactly
2014-03-14T09:34:58 < madist> now I'm trying to use the VL Discovery as a STLink dongle.
2014-03-14T09:35:01 < madist> that's the part that doesn't work.
2014-03-14T09:35:03 < tp> ahh ok
2014-03-14T09:35:16 < madist> The STLink utility connects to the F103, but it can't connect to the F100
2014-03-14T09:35:23 < tp> yeah I think the SWD pins on the VL discovery are then back the front
2014-03-14T09:35:34 < dongs> R2COM: wat is this mega old shit
2014-03-14T09:36:16 < tp> I only went as far as flashing the stlink V2 onto the VL discovery and then talking to the VL via the Linux box (iirc)
2014-03-14T09:37:03 < tp> madist:  I followed a howto I found on the Internet when I did it
2014-03-14T09:37:03 < madist> tp: you did not use the VL to debug anything after flashing it ?
2014-03-14T09:37:38 < tp> madist:  no, I only wanted to flash it and verify it flashed properly
2014-03-14T09:37:38 < dongs> jesus. TLC59282 is like 17cents.
2014-03-14T09:37:42 < madist> ok

2014-03-14T09:38:04 < PaulFertser> madist: and you can check its sources to see what's different between stlinkv1 and stlinkv2
2014-03-14T09:38:16 < madist> oh. good idea.
2014-03-14T09:38:41 < madist> PaulFertser: you're on linux ?

2014-03-14T09:39:36 < madist> this should be trivial. The schematic for the VL is in the VL Discovery User Manual, and same for the F4.
2014-03-14T09:39:44 < madist> I'm just having a brainfail week.
2014-03-14T09:40:04 < Cyric> hey guys... one question...do you think that i can make two STM32 communicate each other by UART (TX RX only) without any external clock?... is the MSI internal clock accurate enought?
2014-03-14T09:40:26 < madist> huh. someone asked that exact same question yesterday.
2014-03-14T09:40:33 < Cyric> was me :)
2014-03-14T09:40:41 < Cyric> i just went to sleep
2014-03-14T09:40:52 < tp> Cyric:  I've not used serial comms on STM32, but if it does async comms, it should be fine
2014-03-14T09:41:25 < Cyric> wel async connection it actually use the start bit for sync
2014-03-14T09:41:36 < tp> sure
2014-03-14T09:41:52 < tp> so many variables, speed, temperature etc
2014-03-14T09:42:17 < tp> serial comms usually involves a xtal in my experience
2014-03-14T09:42:34 < Cyric> and than it start counting the cycles for each bit... so if the two clocks are too different thatn you cannot commnicate
2014-03-14T09:42:40 < tp> sure
2014-03-14T09:42:54 < Cyric> i would like to avoid xc
2014-03-14T09:43:02 < Cyric> it consume too much
2014-03-14T09:43:15 < Cyric> 2 fu**ing mA
2014-03-14T09:43:23 < tp> if you cant afford a xtal for async, use a clock do synchronous comms ?
2014-03-14T09:43:24 < Cyric> only for oscillate
2014-03-14T09:45:13 < Cyric> that may be a solution... but i never set a a sync communication.. how i should set USART_CLK?
2014-03-14T09:45:22 < Cyric> i mean one should be master and one slave
2014-03-14T09:45:56 < tp> I cant help there, Im not familiar with that on the STM32 as yet
2014-03-14T09:46:04 < Cyric> i will give a look at the docs
2014-03-14T09:48:18 < Cyric> actually using a xo it will be quite costly in all the ways...it adds 2 dollar more to the cost+ area (more pcb)+ 2ma to oscillate + more power used from the STM32 because i have to use the HSE instead of MSI
2014-03-14T09:49:37 < Cyric> hey but wait a second.. from the low power specification i read that L version in low power run only accept clock from MSI... and it keeps USART running... so IT MUST WORK
2014-03-14T09:50:11 < Cyric> mmm probably they would use it as sync anyway...

2014-03-14T09:59:52 < PaulFertser> madist: and led is different. Other than that seems to be the same...

2014-03-14T10:00:26 < madist> PaulFertser: if its not a hardware difference, then I'm probably out of ideas
2014-03-14T10:00:30 < dongs> PaulFertser: coo
2014-03-14T10:01:20 < PaulFertser> dongs: do you need firmware from full stlink? (this one was from f4disco, the difference is that full stlink can also SWIM for stm8)
2014-03-14T10:01:49 < PaulFertser> madist: what does openocd say when you try to connect to your "stlinkv2"?
2014-03-14T10:02:00 < dongs> PaulFertser: once you have bootloader, you can just upgrade to full one by debugigng the update.exe and changing board type when it checks for it
2014-03-14T10:02:06 < madist> haven't tried it. just a sec.
2014-03-14T10:02:20 < dongs> (this is how i flashed full stlink on some old -disco i had
2014-03-14T10:02:29 < PaulFertser> dongs: I guess yes, ok. Ping me if anything's missing.
2014-03-14T10:02:39 < dongs> but when you trash the stm32 on stlink (like 12V to a pin or something) and replace with a new chip, w/o bootloader its kinda useesls.
2014-03-14T10:03:02 < madist> PaulFertser: the file you linked earlier is just JTAG without SWIM ?
2014-03-14T10:03:12 < dongs> swim is for stm8 anway

2014-03-14T10:03:31 < PaulFertser> madist: probably you need to pull down pin2 on stlinkv1 for stlinkv2 firmware to work.
2014-03-14T10:03:37 < madist> but the firmware I'm using has both JTAG+SWIM and I don't know if that might be the cause of the problem.

2014-03-14T10:20:15 < tp> madist, you have short SWD wired ?

2014-03-14T10:29:55 < Cyric> i have a question.. if i have something that generate strings and send it over usart... how do i read them by having only one function USART_GET_CHAR
2014-03-14T10:30:23 < Cyric> i mean...how do i know when the trasmission is completed?`
2014-03-14T10:30:47 < jpa-> you don't
2014-03-14T10:30:52 < Cyric> whitout getting stuck in a loop
2014-03-14T10:31:00 < jpa-> you have to e.g. use a terminator character like "0"
2014-03-14T10:31:08 < jpa-> or timeout
2014-03-14T10:31:36 < Cyric> so can i make up one char and use at termination?
2014-03-14T10:32:21 < Cyric> i will probably use one strange char such as §
2014-03-14T10:32:46 < Cyric> thanks jpa
2014-03-14T10:32:47 < jpa-> why not use 0x00, that's what is usually used for the purpose
2014-03-14T10:33:24 < Cyric> cool... i guess is better...
2014-03-14T10:33:27 < Cyric> :D
2014-03-14T10:34:27 < Cyric> actually no... because if need to tranfer a register wich as a 0 value?
2014-03-14T10:34:48 < Cyric> or do i transfer the ascii value 0?
2014-03-14T10:39:47 < tp> Cyric:  best to use a protocol that you can use a commercial analyser if you need to debug
2014-03-14T10:40:17 < tp> so a common protocol like ascii if it fits your design
2014-03-14T10:40:54 < tp> I always think about debugging first
2014-03-14T10:41:14 < Cyric> yes i will do that

2014-03-14T10:44:13 < tp> if it's not a protocol, a lot of people are wrong ?
2014-03-14T10:44:19 < jpa-> which basically means "ascii based custom protocol"
2014-03-14T10:44:25 < jpa-> most of which are total crap
2014-03-14T10:44:35 < jpa-> yes, lot of people on the internet are wrong :)

2014-03-14T10:45:37 < jpa-> by saying "ASCII protocol" you do not actually tell anything about how the data is transferred, except that a part of it is probably text

2014-03-14T10:46:20 < tp> protocols are just a form of data, the transfer mechanism is a seperate thing ?
2014-03-14T10:47:24 < tp> for instance, my HP protocol analyser, can select ASCII or ECBDIC
2014-03-14T10:47:45 < tp> and it's imortant to know which is in use, or one cant read the data

2014-03-14T10:48:44 < nine-tails> dongs: what cameras do you use on your arudino-quad ?
2014-03-14T10:48:54 < tp> I'm used to being me
2014-03-14T10:50:53 < Cyric> i am looking the acii table and is seems that there are few char that are useful.. one is NUL (00x0) one is ENDof TEXT (ETX 0x03) and the other one is END of TRASMISSION (0x04)...
2014-03-14T10:51:47 < jpa-> Cyric: if you are transferring binary data, such as register values, without encoding them using hex or base64, you cannot use *any* character as terminator
2014-03-14T10:52:05 < Cyric> now.. if i use any serial terminal what character they use for terminating the trasmission?
2014-03-14T10:52:15 < jpa-> if you are building a complex protocol, i would use nanopb or json; but i am horribly biased here
2014-03-14T10:52:29 < tp> Cyric:  you can use the EOT character and the ACK etc
2014-03-14T10:52:33 < jpa-> Cyric: they don't, there is no universal standard
2014-03-14T10:53:14 < Cyric> actually i am just trying to send few bytes between one uC to a second uC...
2014-03-14T10:53:33 < Cyric> and i thought that usart was the best way..
2014-03-14T10:53:35 < jpa-> what do the few bytes contain?
2014-03-14T10:53:44 < Cyric> data
2014-03-14T10:53:49 < tp> thats true, but if you're monitoring the transmission, and you see ACk's and NAK's plus EOT's, you can figgure out whats happenning
2014-03-14T10:53:51 < jpa-> duh, what kind of data?
2014-03-14T10:54:10 < Cyric> sensor data
2014-03-14T10:54:26 < tp> ASCII is probably perfect then
2014-03-14T10:54:28 < jpa-> encode as hex?
2014-03-14T10:54:31 < Cyric> plus some more info
2014-03-14T10:54:34 < jpa-> or print as a decimal number
2014-03-14T10:54:40 < Cyric> total 32byte datagram
2014-03-14T10:54:40 < tp> is it a low speed rate ?
2014-03-14T10:54:44 < Cyric> low
2014-03-14T10:54:47 < jpa-> then you can use ascii and 0x00 as terminator
2014-03-14T10:55:05 < jpa-> if the datagram is always 32 bytes, why do you need to terminate anyway?
2014-03-14T10:55:10 < jpa-> you know to read 32 bytes.
2014-03-14T10:55:21 < Cyric> you i have to implement a scanf where i say
2014-03-14T10:55:38 < Cyric> if you receive 0x00 that break
2014-03-14T10:55:43 < Cyric> than
2014-03-14T10:55:48 < Cyric> something like that...

2014-03-14T15:36:04 < Cyric> with some boot code...
2014-03-14T15:36:06 < dongs> if you dont configure, your shit is progbably setup to wahtever system_stm32fxx.c does
2014-03-14T15:36:14 < dongs> assuming you using stderpihlib
2014-03-14T15:38:07 < dongs> which is HSE, with HSE_VALUE for crystal
2014-03-14T15:38:13 < dongs> which i  think defaults to 8 on F1 and 25 on F4
2014-03-14T15:38:16 < dongs> beyond that no idea
2014-03-14T15:38:24 < Steffanx> Hmm, to redesign pcb or to bit bang i2c...
2014-03-14T15:38:52 < dongs> bitbang of course
2014-03-14T15:38:58 < dongs> i2c is worthless anyway.

2014-03-14T15:39:18 < dongs> < Steffanx> I hear altium is no better than kicad
2014-03-14T15:39:26 < dongs> but at least altium has working copper pours and DRC..
2014-03-14T15:39:34 < Robint91> Steffanx, what is connected on the i2C
2014-03-14T15:39:46 < Steffanx> temp/humidity sensor Robint91
2014-03-14T15:40:52 < Steffanx> It's not connected to it yet. I intended to use some sensor with SPI, but this i2c one is much cheaper
2014-03-14T15:40:55 < Steffanx> and im a cheapass
2014-03-14T15:41:13 < Steffanx> and this i2c one is much easier to buy
2014-03-14T15:41:19 < Robint91> dongs, it is even strange that almost no tool has online DRC in chipdesign

2014-03-14T15:46:10 < Steffanx> It's cheaper, not cheap ;)

2014-03-14T15:47:54 < Steffanx> mouser sells the si7020 for ~$3.85/pcs

2014-03-14T15:49:12 < Steffanx> Yeah, and for me kind of only available on ebay.
2014-03-14T15:49:36 < Steffanx> for twice the price of the si7020
2014-03-14T15:50:05 < karlp> I've used this one a bit, which is cheaper if you don't get it from sparkfun https://www.sparkfun.com/products/10167
2014-03-14T15:50:31 < karlp> but it's bulky too
2014-03-14T15:50:44 < Steffanx> yeah, but 3.3V. I running on ~2.3-2.7V
2014-03-14T15:51:04 < karlp> cool :)
2014-03-14T15:51:19 < karlp> these work well, but you need a way of reading capacitance: http://www.digikey.com/product-search/en?WT.z_header=search_go&lang=en&site=us&keywords=hch1000&x=-1693&y=-51&formaction=on

2014-03-14T15:52:36 < Steffanx> Still the boring temp/hum/motion sensor :P
2014-03-14T15:52:42 < Steffanx> I work slow.
2014-03-14T15:53:10 < madist> DHT11 is terribly inaccurate I heard ?
2014-03-14T15:53:27 < madist> its made by some no-name company in China
2014-03-14T15:53:28 < karlp> pretty much in spec, depends what you were expecting.
2014-03-14T15:53:55 < karlp> temp is pretty good, stable, humidity seems reasonable and is quite sensitive,
2014-03-14T15:54:04 < karlp> it's _terrible_ if yuou don't give it 3.3V or more,
2014-03-14T15:54:12 < karlp> 3.0V will give you replies, but it will be mostly garbage
2014-03-14T15:54:12 < madist> what about the encoding ?
2014-03-14T15:54:20 < karlp> tedious bit banging
2014-03-14T15:54:23 < Steffanx> oh, so 2.3V is not an option.
2014-03-14T15:54:31 < karlp> for the DHT11, no,
2014-03-14T15:54:47 < Steffanx> I already use the pir sensor a bit out of spec, but it seems to work well enough.
2014-03-14T15:54:47 < karlp> which is what madist was asking about
2014-03-14T15:55:37 < madist> SHT11 is a bit better I hear.
2014-03-14T15:55:49 < Steffanx> different sensor..
2014-03-14T15:55:56 < madist> different company
2014-03-14T15:55:58 < Steffanx> sht10 = quality because swiss made :P

2014-03-14T16:15:25 < dongs> you broke it
2014-03-14T16:15:38 < dongs> send 0xAA repeatedly over uart, and check wiht scope
2014-03-14T16:15:44 < dongs> to make sure you're sending at baudrate you're expecting?
2014-03-14T16:15:56 < Cyric> everything is the same
2014-03-14T16:16:03 < Cyric> only the clock source is different
2014-03-14T16:16:17 < Cyric> if i switch it back it works fine
2014-03-14T16:16:32 < Cyric> this instruction here
2014-03-14T16:16:33 < Cyric> CC_HSICmd(ENABLE);
2014-03-14T16:16:33 < Cyric>    RCC_SYSCLKConfig(RCC_SYSCLKSource_HSI);
2014-03-14T16:17:03 < Cyric> if i set MSI instead it works fine
2014-03-14T16:18:58 < Cyric> i suspect that is the accuracy of HSI that is not good enought....
2014-03-14T16:19:18 < Cyric> how can i check that?
2014-03-14T16:20:32 < dongs> < dongs> send 0xAA repeatedly over uart, and check wiht scope
2014-03-14T16:21:03 < Cyric> the first microcontroller is sending the same...
2014-03-14T16:21:24 < Cyric> the code is still the same
2014-03-14T16:21:33 < Cyric> is the receiver that create problem...
2014-03-14T16:22:15 < Cyric> ok let me try one thing
2014-03-14T16:23:43 < englishman> the point of sending AA is to check the clock
2014-03-14T16:23:46 < englishman> as it makes 01010101
2014-03-14T16:24:00 < englishman> so you need to send it from the chip whose clock you are inspecting

2014-03-14T16:29:10 < Steffanx> englishman, how is digikey not reliable? I think jpa- used it because it seems to be the only supplier with some fancy way to get the data in a csv
2014-03-14T16:29:19 < zyp> Steffanx, it's expensive
2014-03-14T16:29:20 < englishman> i mean price-wise
2014-03-14T16:29:38 < Cyric> i just modified MSI with HSI
2014-03-14T16:29:38 < englishman> but it guess it serves the purposes of the plot
2014-03-14T16:29:55 < Cyric> so i haven't touched the prescaler
2014-03-14T16:29:58 < zyp> digikey is not where you'd buy larger quantities of chips, unless you want to waste a bunch of money
2014-03-14T16:29:58 < Steffanx> isn't digikey cheap compared to many others? Like farnell
2014-03-14T16:30:03 < Steffanx> and mouser sometimes
2014-03-14T16:30:13 < zyp> dunno about farnell, but mouser tends to be cheaper for stm32
2014-03-14T16:30:22 < englishman> yeah and dont forget waveshare
2014-03-14T16:30:30 < englishman> and it really depends on the product
2014-03-14T16:30:35 < dongs> zyp, ever used BUS? cant seem to figure out how it works
2014-03-14T16:30:40 < Steffanx> waveshare englishman \o/
2014-03-14T16:30:43 < dongs> at least i can't attach port labels to it..
2014-03-14T16:31:00 < dongs> maybe i should rtfm first
2014-03-14T16:31:29 < zyp> in altium? no
2014-03-14T16:31:48 < Steffanx> didnt know dk was more expensive, never order from them.
2014-03-14T16:32:07 < dongs> mouser seems to have a fair bit of ST stuff that dk doesnt even stock
2014-03-14T16:32:11 < dongs> masybe they have some special deal

2014-03-14T16:38:42 < dongs> i really dont like that i cant just rename arbitrary nets without dropping down netlabel
2014-03-14T16:39:44 < zyp> what do you mean?
2014-03-14T16:40:01 < dongs> i have a net from say PA2 to a resistor
2014-03-14T16:40:10 < dongs> it's gonna be called Net_IC?_PA2 or wahtever
2014-03-14T16:40:14 < dongs> unless I put a net label on it
2014-03-14T16:40:20 < dongs> there's no way to rename it otherwise
2014-03-14T16:40:56 < zyp> I'm using ports on pretty much everything, and I checked the «allow ports to name nets» option
2014-03-14T16:41:06 < zyp> so I'm getting all my nets named by ports
2014-03-14T16:41:08 < dongs> ports? the yellow shits?
2014-03-14T16:41:10 < zyp> yes
2014-03-14T16:41:18 < dongs> well, its same  thing
2014-03-14T16:41:24 < dongs> what im saying is that i cant JUST RENAME A NET.
2014-03-14T16:41:32 < dongs> i have to attach a label or port or whatever to it
2014-03-14T16:41:37 < dongs> dicktracae i can just have  wire, and name it
2014-03-14T16:41:42 < dongs> and choose whether i wanna show that name or not
2014-03-14T16:41:52 < zyp> dunno, I haven't attempted it
2014-03-14T16:42:22 < talsit> zyp: where do you enable the <allow ports to name nets>?
2014-03-14T16:42:25 < zyp> if I care about the name of a net, it's going to show up in the schematic as a port or something anyway
2014-03-14T16:42:35 < zyp> talsit, project preferences IIRC
2014-03-14T16:42:43 < talsit> cheers
2014-03-14T16:42:43 < dongs> zyp,  yeah. well, i care about *all* nets. btut i guess im gonna have to stop.
2014-03-14T16:44:02 < talsit> zyp: awesome, found it, cheers
2014-03-14T16:44:17 < zyp> when I'm drawing shematics I'm usually putting the MCU GPIO banks on one sheet, and just do a bunch of ports connecting to them
2014-03-14T16:46:05 < zyp> http://bin.jvnv.net/f/SU1IJ.png <- like this
2014-03-14T16:46:21 < zyp> the only unnamed nets on that sheet are the two usb signals between the resistors and the connector

2014-03-14T16:48:18 < zyp> depends on what the pin is defined as
2014-03-14T16:48:38 < zyp> I believe default rules only bitch about unconnected inputs

2014-03-14T17:28:13 < dongs> when it works its great but half the time it ends up in totally wrong place than waht i told it to be in
2014-03-14T17:29:00 < dongs> and why hte fuck stuff doenst snap to center of pins/etc
2014-03-14T17:29:17 < dongs> zyp, any way to make the 'offset' selector after copy snap to center of pin?
2014-03-14T17:29:47 < zyp> what do you mean?
2014-03-14T17:30:01 < dongs> i dunno, when youhit ctrl+c you need to place cursor somewehre and click first
2014-03-14T17:30:04 < dongs> for the offset
2014-03-14T17:30:10 < zyp> ah, right
2014-03-14T17:30:10 < dongs> but obviosuly i want that to be pins center
2014-03-14T17:30:21 < zyp> isn't pin's center on grid?
2014-03-14T17:30:28 < zyp> if not, adjust the grid to fit
2014-03-14T17:30:35 < dongs> nah. DB25 faggotry
2014-03-14T17:30:39 < dongs> i think i got it using j-l
2014-03-14T17:30:50 < dongs> re-centered cursor on exact coords after copy
2014-03-14T17:31:06 < zyp> anyway, are you using array paste?
2014-03-14T17:31:09 < dongs> yes
2014-03-14T17:31:32 < zyp> just copy, paste and worry about position afterwards
2014-03-14T17:31:48 < dongs> how? you arent gonna get it aligned any easier if its in wrong place
2014-03-14T17:32:44 < zyp> changing the grid in altium is so easy that there's no reason to dick around with a grid that doesn't match the component's pitch
2014-03-14T17:32:49 < zyp> you can even do different x/y pitch

2014-03-14T17:39:14 < madist> infact, I accidentally put in a 10k resistor instead of 100 ohms (as per the F4 schematic) and it worked anyway.

2014-03-14T20:34:56 < zyp> I'd be pretty annoyed if I had to use libs _without_ debugging symbols
2014-03-14T20:35:24 < jpa-> well i'd be annoyed at libs without source.. and if i have source, i build it myself anyway
2014-03-14T20:35:49 < zyp> true true
2014-03-14T20:35:54 < jpa-> unless it is only buildable with some commercial compiler

2014-03-14T21:08:44 < aadamson> yeah, was just a change from 3.2 to 4.0 it seems... builds with 3.2 down have debugging in the arm math libs, 4.0 do and I wasn't expecting that
2014-03-14T21:09:05 < aadamson> and I couldn't figure out why the heck the build from 3.2 was 40k and the build with 4.0 was over 200
2014-03-14T21:09:40 < aadamson> till I turned off the arm math libs and just linked regular libs and poof, the size came down to what it should have been
2014-03-14T21:11:24 < aadamson> trying to see if I have some other *switch* turned on that made the change because the size of the math libs are similar between 3.2 and 4.0 so maybe I'm stripping in one case and not in the other (may have missed a build configuration under eclipse I suppose - it's separate builds environments until I know the new version works :> )
2014-03-14T21:13:19 < fbs>  --gc-sections usually helps a lot with gcc
2014-03-14T21:13:36 < fbs>  -fdata-sections
2014-03-14T21:15:29 < aadamson> those are already handled, its something else
2014-03-14T21:16:16 < fbs> software floats?
2014-03-14T21:18:42 < aadamson> I would doubt that software floats vs. arm software floats would do that... all I know is if I build with the libm vs arm_cortexM3l_math for sin/cos etc, the build grows from 40k to over 200k :)
2014-03-14T21:19:43 < fbs> how big are the lib files?
2014-03-14T21:20:44 < aadamson> 2.9M
2014-03-14T21:20:51 < fbs> hmm
2014-03-14T21:20:56 < aadamson> but both 3.2 and 4.0 are similar
2014-03-14T21:21:46 < fbs> what if you comare the sections in tuebresulting elfs
2014-03-14T21:21:53 < aadamson> hmm, link line is identical with the exception of 3.2 vs 4.0... hmm... I think I'll try linking the 3.2 libs on the 4.0 build environemtn just for kicsk
2014-03-14T21:22:01 < aadamson> yeah going to do that next as well
2014-03-14T21:24:11 < aadamson> well, there ya go... just linking in the 3.2 arm math libs, size is where it should be, linking the 4.0's it's 4x the size... so it's for sure the lib, not build environment.
2014-03-14T21:24:59 < fbs> can you compile both withbthe same flags?

2014-03-14T21:26:24 < aadamson> yes, it's exactly the same compile/link lines on both all I did was change the include path for the arm math lib
2014-03-14T21:28:38 < aadamson> well, for now I don't want to mess with this... I'm on on a CM3 so I'll just like in the libm and remove the arm math libs... until I get some time to deal with this... as noted not a huge issue but I was trying to reference a/b build sizes and all of a sudden I was 4x-5x bigger... wooo hooo
2014-03-14T21:28:43 < aadamson> for a 128k part :)

2014-03-14T21:44:45 < aadamson> Finished building: STM32L1-flight.siz
2014-03-14T21:44:59 < jpa-> ok
2014-03-14T21:45:15 < aadamson> that's with libm or the 3.2 arm math lib (it's a slight bit larger), with the 4.0 math lib, that is 200+k
2014-03-14T21:45:31 < jpa-> arm-none-eabi-objdump -t foo.elf | sort -k 5 is sometimes helpful to see the largest functions
2014-03-14T21:46:16 < aadamson> yeah... I'll take a look at that and see sometime... it's just odd that 3.2->4.0 caused this and yet the libs are similar in size

Malaysia Airlines is one of Asia’s largest, flying nearly 37,000 passengers daily. As of today, we are beginning the 37th month since the Fukushima tragedy, which is locate
2014-03-15T03:21:15 < Laurenceb> d on the 37th degree and initially caused 37 injuries at the plant"
2014-03-15T03:21:21 < Laurenceb> you know it makes sense
2014-03-15T03:22:50 < madisk> An Asia-based pilot of a Boeing 777-200, who asked not to be identified because he was not authorized to speak to reporters, said an ascent above the plane’s service limit of 43,100 feet, along with a depressurized cabin, could have rendered the passengers and crew unconscious, and could be a deliberate maneuver by a pilot or a hijacker.
2014-03-15T03:23:51 < SlaveToTheSauce> it still blows my mind that airliners don't have constant telemetry
2014-03-15T03:23:56 < madisk> they do
2014-03-15T03:24:31 < Laurenceb> it was turned off
2014-03-15T03:24:32 < SlaveToTheSauce> there are systems in place but they aren't pervasively employed, and they aren't long-range
2014-03-15T03:24:34 < madisk> if you want the lowest fares, you get an airline that doesn't pay for the satellite link.

2014-03-15T06:14:06 < zyp> we discuss everything, either because it's interesting or because we ridicule it
2014-03-15T06:14:30 < zyp> what's your definition of a high speed

2014-03-15T06:22:06 < MrTrick> I'm not completely certain yet, but maybe 100khz? I need to do some goertzel and convolution stuff as well, so it needs to work without too much overhead.
2014-03-15T06:22:12 < MrTrick> It's the F401 board.
2014-03-15T06:23:45 < zyp> 100kHz doesn't sound particularly fast, but I don't remember the specs of the F4 ADC now
2014-03-15T06:24:31 < GargantuaSauce> it can do well over a MHz ithink
2014-03-15T06:25:11 < zyp> 2.4 MSPS according to datasheet, per ADC

2014-03-15T06:27:40 < zyp> and you're pretty much required to use DMA for ADC in the first place, so it'll work without any CPU overhead anyway
2014-03-15T06:28:50 < zyp> you can just set it up in dual buffer mode which then gives you one block of data to work on (of whatever number of samples you want) while DMA samples into the other block
2014-03-15T06:29:20 < MrTrick> zyp: Fair enough. Now, how on earth do I do that inside the mbed platform?
2014-03-15T06:29:33 < zyp> that much I don't know :)
2014-03-15T06:29:37 < MrTrick> (I've used 8-bit AVR and PICs, never any 32 bit stuff)
2014-03-15T06:30:31 < zyp> well, in this regard it's not a matter of 8-bit vs 32-bit, it's a matter of library APIs
2014-03-15T06:31:32 < zyp> I don't know what the mbed library provides or how hard it would be to add an additional library to the mbed IDE
2014-03-15T06:32:08 < GargantuaSauce> it looks like its hal does have provisions for dma transfers from the adc
2014-03-15T06:32:18 < GargantuaSauce> i dont particularly like the look of this api though
2014-03-15T06:32:46 < zyp> I've only used the old mbed stuff with the lpc17xx
2014-03-15T06:32:58 < zyp> but I found the API to be a bit saner than arduino
2014-03-15T06:35:36 < zyp> MrTrick, the way the hardware works is that you configure the DMA peripheral with a list of the channels you want to scan, then it will iterate across that list and output the results one by one
2014-03-15T06:35:46 < zyp> ADC peripheral*
2014-03-15T06:36:14 < zyp> then you configure the DMA peripheral to take each result and shove them into a memory buffer you've provided

2014-03-15T08:17:31 < PaulFertser> What would be the cheapest way to make a microcontroller device that would support "gigabit ethernet" phy layer? The actual throughput doesn't matter at all.
2014-03-15T08:18:23 < ds2> make a ethernet enabled device and add a cheap GigE switch?

2014-03-15T08:20:33 < PaulFertser> ds2: well, yes, that would be one option, but I'm afraid those military stupids that demand gigabit are not that stupid and won't allow it. I'll try to propose it nevertheless. Any other options probably?
2014-03-15T08:21:28 < PaulFertser> They're not likely to allow us to use some cheap off-the-shelf switch inside a device :/
2014-03-15T08:22:05 < dongs> a gigabit switch IC then?>
2014-03-15T08:22:12 < dongs> realtek ones hould be cehap
2014-03-15T08:22:15 < dongs> 2 port :)
2014-03-15T08:23:39 < PaulFertser> Yes, that's more likely.
2014-03-15T08:24:14 < PaulFertser> So stm32f105 or some such with ethernet mac + any phy + switch would probably be a valid combination.
2014-03-15T08:27:54 < dongs> demanding gige without throughput requiremnt is pretty dum
2014-03-15T08:28:01 < dongs> do they just want all thier leds to be green on the swtich? :)
2014-03-15T08:28:11 < PaulFertser> They also demand two ports of it "for backup".
2014-03-15T08:28:52 < PaulFertser> So it needs to be a 3-port switch at least :)

2014-03-15T08:45:23 < dongs> that appears to be 100m
2014-03-15T08:46:13 < qyx_> do they even have lights on their switches?

2014-03-15T12:58:27 < Claude> per net name
2014-03-15T12:58:32 < dongs> where?
2014-03-15T12:58:38 < dongs> lets say i wanna make gnd blue or something
2014-03-15T12:59:04 < dongs> i gota say tho, net labels are kinda neat for pin swapping

2014-03-15T12:59:30 < dongs> wahts the key combo to that
2014-03-15T12:59:38 < Claude> moment
2014-03-15T13:00:42 < Claude> ah don't know the combo , but left click on the net -> net actions -> properties
2014-03-15T13:01:10 < dongs> yiss
2014-03-15T13:01:16 < dongs> slightly better
2014-03-15T13:01:24 < dongs> i'd have preferred to have pads etc colroed like that
2014-03-15T13:01:34 < Claude> oh nice there is a per-net 'remove loop' option :)
2014-03-15T13:02:04 < dongs> whats that do?

2014-03-15T13:02:44 < dongs> next one is again no net
2014-03-15T13:02:50 < Claude> hmm e.g. you have to 'stitch' down something with gnd vias , ad by default removes the ground loops

2014-03-15T13:49:41 < nine_tails> win 8 pro.. im sure
2014-03-15T13:51:08 < Claude> gongs , you have to set the default/prefered via sizes in the rules

2014-03-15T13:52:43 < Claude> you can also set the rules per net class
2014-03-15T13:52:47 < dongs> it makes them MAX size.
2014-03-15T13:52:59 < Claude> ah okay let me check
2014-03-15T13:53:13 < dongs> i mean if i set max to waht i want it works

2014-03-15T14:48:50 < dongs> THAT

2014-03-15T14:49:45 < zyp> yes
2014-03-15T14:50:05 < zyp> and component to component distance too
2014-03-15T14:50:46 < zyp> since that counts from the edge of the silk outline, which already provides enough distance as is
2014-03-15T14:50:49 < dongs> hm yeah, i noticed that when trying to put 0603 next to each other
2014-03-15T14:50:51 < dongs> yes
2014-03-15T14:51:28 < zyp> and then there's silk to mask distance, which also defaults to some silly high value
2014-03-15T14:51:50 < dongs> pretty sure we dont care about that either.
2014-03-15T14:52:00 < dongs> probly only related to some silly ancient process of making mask/silk
2014-03-15T14:52:17 < zyp> yeah
2014-03-15T14:52:42 < dongs> component clerance, is that the minimum horizontal clearance hsit?
2014-03-15T14:52:52 < zyp> yes
2014-03-15T14:53:12 < zyp> vertical clearance only matters if you actually have 3d models for the components
2014-03-15T14:53:12 < dongs> does that actually use 3d crap to alcualte shit
2014-03-15T14:53:25 < zyp> it does if you have them
2014-03-15T14:53:31 < dongs> i did add 3d body to a few things
2014-03-15T14:53:34 < dongs> that i know how high they are
2014-03-15T14:53:36 < dongs> not that it matters really
2014-03-15T14:53:40 < dongs> just rectangle
2014-03-15T14:53:42 < zyp> otherwise vertical clearance is ignored and horizontal clearance is just outline

2014-03-15T15:45:19 < dongs> hmm... this is kinda lame. i have a pushbutton which has lots of space inside of it
2014-03-15T15:45:22 < dongs> for caps/r
2014-03-15T15:45:28 < dongs> but the shit thinks its rectangular
2014-03-15T15:45:48 < dongs> so it starts throwing out errors right as i touch any outer edge
2014-03-15T15:47:23 < dongs> maybe i should try keepout layer.
2014-03-15T15:49:00 < dongs> http://www.edaboard.com/thread170389.html oops
2014-03-15T15:50:28 < Steffann> "Ignore the DRC"  yay :P
2014-03-15T15:50:33 < dongs> yep
2014-03-15T15:51:19 < dongs> its not a big deal i got lost of space but meh
2014-03-15T15:51:25 < dongs> all that 3d faggotry and such simple shit fails
2014-03-15T15:51:48 < dongs> ive got a pushutton that looks ilke [
2014-03-15T15:51:51 < gxti> dongs: actually if you put a 3d body on the pushbutton it will be used for collision detection
2014-03-15T15:52:09 < dongs> no way
2014-03-15T15:52:15 < gxti> ya wai
2014-03-15T15:52:15 < dongs> even in 2d mode?
2014-03-15T15:52:24 < zyp> yes, but it must be a proper 3d model
2014-03-15T15:52:29 < zyp> that's what the 3d stuff is for
2014-03-15T15:52:35 < dongs> blah
2014-03-15T15:52:46 < gxti> well you can do it with the shitty ones you place in the pcb library if you really want to
2014-03-15T15:52:57 < dongs> gxti, i tried that
2014-03-15T15:53:05 < dongs> well, ok. acutalyl i didnt. lemme tr that with just 3d body.
2014-03-15T15:53:35 < zyp> the 3d body at least needs to have the gap where you want to place the components
2014-03-15T15:54:22 < dongs> ooo
2014-03-15T15:54:23 < dongs> very nice
2014-03-15T15:54:24 < dongs> worked
2014-03-15T15:54:24 < zyp> and I guess the components that goes underneath also needs to have height so DRC know they are low enough to not collide
2014-03-15T15:54:38 < gxti> probably yes

2014-03-15T16:14:11 < dongs> On behalf of the Altium Development team, I.m excited to announce the release of Altium Designer 14.2. This update continues the focus on fixes, enhancements and performance to our core technologies. Approaching 100 fixes/enhancements in total, and addressing 30 popular issues raised in our BugCrunch system.
2014-03-15T16:14:22 < dongs> this shit is just crashing CONSTANTLY
2014-03-15T16:14:36 < scrts> did you buy it?
2014-03-15T16:14:39 < scrts> you can report... :)
2014-03-15T16:15:01 < dongs> dicktrace crashed on me like.... 5 times in 5 years
2014-03-15T16:15:15 < dongs> no, i didnt, but i might consider when they actually stop crashing every 5 minutes :)
2014-03-15T16:15:26 < dongs> (and relase a version thats affordable without shit I dont need)
2014-03-15T16:15:53 < dongs> paying $5k and unchecking "FPGA tools" on install isn't very good use of my paypal funds.
2014-03-15T16:19:18 < scrts> hmmm
2014-03-15T16:19:24 < scrts> what is the cheapest version now?
2014-03-15T16:19:31 < scrts> I mean sch+pcb only
2014-03-15T16:19:38 < dongs> right, there isnt one like that
2014-03-15T16:19:39 < scrts> it was like >10k before
2014-03-15T16:19:40 < dongs> its all or nothing
2014-03-15T16:19:43 < dongs> fpga,spice,trash
2014-03-15T16:19:46 < scrts> pff...
2014-03-15T16:20:25 < dongs> Altium Designer 14 pricing starts at $7,245 USD, including a one year subscription. Extended services and custom support packages are available from Altium and our extended network of value added resellers worldwide
2014-03-15T16:20:30 < dongs> haha
2014-03-15T16:21:06 < gxti> i'm using 14.1 and it hasn't crashed once yet, the version 10 i was on for a long time was a different story
2014-03-15T16:21:28 < gxti> somtimes if i went too long without running a 'compile' on the schematic it would flip its shit, hilarious
2014-03-15T16:22:23 < scrts> the last I've used it was v13
2014-03-15T16:22:32 < scrts> but the via stitching options was damn cool
2014-03-15T16:22:38 < scrts> for RF PCBs

2014-03-15T21:59:48 < zippe> jpa-: I'm trying to rip off the laks GPIO class on the AVR, and wondering how to get the port reference to be const
2014-03-15T22:00:01 < zippe> It doesn't seem to want to DTRT
2014-03-15T22:01:06 < zyp> references are always const
2014-03-15T22:02:00 < zippe> Except you can take the address of the reference and cast that to pointer-to-pointer
2014-03-15T22:02:17 < zippe> But more specifically, they seem to be insufficiently const for the compiler to optimise them away.
2014-03-15T22:03:07 < zyp> are you making the instances static? if not the compiler must emit the objects
2014-03-15T22:04:46 < zippe> Ah, it's a side-effect of -Os
2014-03-15T22:05:06 < zippe> -O2 saves ~200 bytes and now I have no data segment pollution
2014-03-15T22:07:08 < zyp> so -O2 generates a smaller file than -Os? that's interesting
2014-03-15T22:10:49 < zippe> Well, currently the code's still very small
2014-03-15T22:11:06 < zippe> Tradeoffs might change later
2014-03-15T22:12:08 < zyp> that's true, I'm just wondering what optimization -Os omits that in this case makes the output smaller
2014-03-15T22:12:53 < zyp> since -Os is supposed to be -O2 sans size-increasing optimizations
2014-03-15T22:14:42 < aadamson> stupid q of the day... if I have a stm32l152C discovery (256k part) and I want to target an application for a B part (128K)... can I built it for B and run it on the C part with no problem?
2014-03-15T22:15:05 < zyp> yes
2014-03-15T22:15:06 < gxti> aadamson: yep
2014-03-15T22:15:11 < aadamson> maybe I have those B's and C's wrong, but you get the drift
2014-03-15T22:15:57 < aadamson> now if they just hadn't changed the stupic USB ID's on the nucleo I could run my app and see if will work... but alas I can't get openocd to connect because it doesn't know the ID change and I really don't want to rebuilt it for windows :(
2014-03-15T22:16:14 < aadamson> rebuild
2014-03-15T22:16:36 < zyp> the only difference in building for B and building for C is the flash size listed in the linker script
2014-03-15T22:17:15 < zyp> so as long as the flash contents are smaller then both sizes, both builds will produce the same output anyway

2014-03-15T22:17:54 < Steffanx> i guess you mean L152xC/B? C parts tend to have more RAM as well
2014-03-15T22:18:07 < aadamson> perfect... thanks zyp, now I just need to figure out openocd or just go for it with the flash tool
2014-03-15T22:18:31 < aadamson> yeah, I'm building with the smaller part linker script so I should be ok, just didn't know if there would be any other issues
2014-03-15T22:18:49 < zyp> Steffanx, I don't know about L1, but for F1 that's true, for F3 it's not
2014-03-15T22:19:01 < Steffanx> I checked, it's true for L1 as well
2014-03-15T22:19:02 < aadamson> it is for the L1's
2014-03-15T22:19:07 < zyp> ok
2014-03-15T22:19:14 < zyp> which are the sizes for each?
2014-03-15T22:19:28 < aadamson> I'm building for an 8 - 128k/16k/4k and I have a B or c (256k/32k/can't remember the eepromsize)
2014-03-15T22:20:03 < aadamson> actually in this case I'm using and *R* and building for whatever the 128k part is...
2014-03-15T22:20:30 < Steffanx> I see ST changed some things. ULP? And what is this -A addition? http://www.st.com/web/catalog/mmc/FM141/SC1544/SS1374

2014-03-15T22:21:24 < Steffanx> oh "device generation A"
2014-03-15T22:21:26 < Steffanx> ok :S
2014-03-15T22:22:59 < aadamson> I know they had an issue with an internal pullup on the usb DP for disconnect, maybe they fixed that and other things in the silicon and rev'd the generation or something
2014-03-15T22:28:45 < Steffanx> They did fix that, the wonderful thing is.. the chips A/non-A have different errata documents :D
2014-03-15T22:28:54 < zippe> aadamson: aren't the USB IDs for openocd in the scripts?
2014-03-15T22:29:22 < aadamson> I don't think so, I found a reference online to fix this but it required a rebuild of openocd.
2014-03-15T22:29:52 < aadamson> haven't looked fully at the issue yet, but it doesn't find the stlink on the nucleo boards
2014-03-15T22:30:40 < zyp> is it a stlink?
2014-03-15T22:33:02 < aadamson> yes
2014-03-15T22:33:24 < aadamson> maybe that's the issue they change the stlink ID between the nucleo and the discovery boards

2014-03-15T23:06:45 < englishman> it's like a more expensive, white discovery?
2014-03-15T23:06:49 < englishman> oh
2014-03-15T23:06:52 < englishman> arduino headers
2014-03-15T23:06:53 < englishman> ???
2014-03-15T23:07:07 < englishman> no wonder it's more expensive then

2014-03-15T23:20:08 < zyp> englishman, isn't it cheaper?
2014-03-15T23:20:47 < englishman> not for me, looking at digikey
2014-03-15T23:20:57 < englishman> at least, it's more expensive than all the non-display models
2014-03-15T23:21:34 < englishman> aww... and digikey raised their prices again on disco boards :|
2014-03-15T23:26:30 < Steffanx> like you need more than one :P
2014-03-15T23:27:21 < aadamson> it's $10 from mouser in the states, much cheaper than discovery and bigger processors
2014-03-15T23:27:40 < englishman> digicrap canada: $18
2014-03-15T23:27:42 < englishman> :|
2014-03-15T23:27:46 < aadamson> but alas, it doesn't have a target usb connection so for me vcp isnt going to work anyway
2014-03-15T23:28:06 < aadamson> have to wait for my ultimate host, but at least the code is ported back from the f3 to now the l1 and it seems to work
2014-03-15T23:28:08 < aadamson> :)
2014-03-15T23:28:15 < englishman> cool
2014-03-15T23:28:22 < englishman> which chips have AF like the F3?

2014-03-15T23:28:40 < aadamson> af?
2014-03-15T23:28:48 < englishman> alternate functions
2014-03-15T23:28:54 < aadamson> dont' they all?
2014-03-15T23:29:05 < englishman> i mean f3 style vs f1 style
2014-03-15T23:29:30 < aadamson> I guess I"m still confused, even the F1 has them
2014-03-15T23:29:34 < englishman> yes
2014-03-15T23:29:35 < aadamson> the l1 did
2014-03-15T23:29:48 < aadamson> they aren't named the same
2014-03-15T23:30:00 < englishman> but i mean how you connect a periph to a pin
2014-03-15T23:30:02 < aadamson> but it was pretty easy to port everything back to the smaller processor
2014-03-15T23:30:09 < aadamson> same way
2014-03-15T23:30:15 < aadamson> just named diff
2014-03-15T23:30:28 < aadamson> instea od AF5 i was AF_USART or somesuch
2014-03-15T23:31:18 < aadamson> http://www.st.com/st-web-ui/static/active/en/resource/technical/document/datasheet/DM00078689.pdf
2014-03-15T23:31:26 < aadamson> eg. page 44/127
2014-03-15T23:31:48 < aadamson> instead of those being AFIO4, I had to go look and see what the AF name was in the stdperiph
2014-03-15T23:31:52 < aadamson> but it was pretty easy to map
2014-03-15T23:32:07 < aadamson> it's just that the F1 datasheet doesn't have those nice charts
2014-03-15T23:32:22 < aadamson> but the l1 and f1 are pretty much straight away compat so I'm sure the same exists on the f1

2014-03-15T23:35:21 < aadamson> yeah, just clock/ram/flash (and l1 has real eeprom) are diff
2014-03-15T23:35:29 < aadamson> but peripherals pins, etc are same
2014-03-15T23:35:39 < aadamson> and power is about 10x less :)

2014-03-16T02:42:00 < gxti> Fleck: it's not going to help you with stm32 peripherals, it's just for the cpu core.
2014-03-16T02:42:24 < Fleck> well, I need to learn cpu core too, right?
2014-03-16T02:42:36 < Fleck> I just don't know where to start
2014-03-16T02:42:55 < gxti> it's not going to help you start anything
2014-03-16T02:43:15 < Fleck> ok, what will?
2014-03-16T02:43:37 < Fleck> cause reading reference manual... well I don't understand every 2nd word/definition there :D
2014-03-16T02:43:40 < nine-tails> Fleck: join me on my calass
2014-03-16T02:43:44 < nine-tails> Fleck: or fuck it
2014-03-16T02:43:48 < gxti> use the stdperiph examples as a starting point, change stuff around and see what happens
2014-03-16T02:43:50 < GargantuaSauce> set up a development environment, read other peoples' code, mess with it
2014-03-16T02:43:54 < nine-tails> Fleck: youtube---> state machine com
2014-03-16T02:44:03 < nine-tails> Fleck: or search "miro samek" on youtube
2014-03-16T02:44:07 < nine-tails> Fleck: he  has guide on stm32
2014-03-16T02:44:09 < nine-tails> f4
2014-03-16T02:44:16 < nine-tails> he shows arhitecture
2014-03-16T02:44:20 < nine-tails> and peripherals
2014-03-16T02:44:33 < nine-tails> on a real board, works in C and steps down to assembloer
2014-03-16T02:44:39 < nine-tails> so you can learn how shit works
2014-03-16T02:44:55 < Fleck> gxti: those examples don't seem to compile on gcc/eclipse so... meh
2014-03-16T02:45:51 < GargantuaSauce> Fleck: get keil or learn to mess with makefiles to make stuff work
2014-03-16T02:45:53 < GargantuaSauce> those are your two options
2014-03-16T02:46:10 < Fleck> keil is windows isn't it?
2014-03-16T02:46:15 < GargantuaSauce> ok then the latter
2014-03-16T02:46:32 < gxti> you can use other people's makefiles without understanding how they work, for a while anyway.
2014-03-16T02:46:32 < GargantuaSauce> the build environment is as important to understand as the architecture

2014-03-16T02:51:56 < Fleck> noo :D

2014-03-16T02:52:23 < nine-tails> .. also the architecture is very intuitive

2014-03-16T03:37:17 < nine-tails> nice trololool
2014-03-16T03:37:33 < GargantuaSauce> there are a few options
2014-03-16T03:37:46 < GargantuaSauce> grab a newlib or other embedded c stdlib implementation including a full heap
2014-03-16T03:38:00 < GargantuaSauce> or halfass one yourself
2014-03-16T03:38:31 < GargantuaSauce> especially if things are never going to actually free() memory, you could just have a big array and malloc() increments a pointer into it
2014-03-16T03:39:06 < cosm0naut> thanks

2014-03-16T03:51:33 < emeb> The Altera Cyclone V SoC stuff seems a bit more mature than the Xilinx Zynq.
2014-03-16T03:51:47 < dongs> they both run lunix
2014-03-16T03:51:50 < dongs> so it doesnt mater
2014-03-16T03:51:54 < dongs> they're both shit
2014-03-16T03:51:59 < nine-tails> you wish
2014-03-16T03:52:00 < emeb> And Quartus licensing has never given me the headaches that Xilinx does.
2014-03-16T03:52:13 < emeb> dongs: waiting for an FPGA that runs Windows CE? :)
2014-03-16T03:52:22 < GargantuaSauce> windows RT now
2014-03-16T03:52:41 < nine-tails> dont please
2014-03-16T03:52:54 < dongs> shittyberrypi theoreticaly could run CE or RT
2014-03-16T03:53:07 < dongs> that might actually make it somewhat useful
2014-03-16T03:53:12 < GargantuaSauce> lol i wonder if someone will port the video drivers now that they're open
2014-03-16T03:53:23 < dongs> i remember someone was working on CE BSP
2014-03-16T03:53:40 < dongs> http://www.raspberrypi.org/forum/viewtopic.php?f=56&t=58259
2014-03-16T03:54:43 < emeb> dongs: actually both Altera and Xilinx do support running bare metal or other OSes on their SoCs
2014-03-16T03:55:01 < dongs> emeb: for sure but you never see anyone doing so
2014-03-16T03:55:09 < emeb> Just the free stuff they give away is all Linux.
2014-03-16T03:55:25 < dongs> every zynq proj ive seen has been filthylunix
2014-03-16T03:56:13 < dongs> i wonder howe many lunix disctributions there are for the hypeberrypi
2014-03-16T03:56:17 < emeb> dongs: one my customers is running VXworks on Cyclone V
2014-03-16T03:56:19 < dongs> im gonna *guess* at least 10
2014-03-16T03:56:44 < nine-tails> fucks. read the ms licence to see how much of bsd they sell you
2014-03-16T03:57:04 < dongs> bsd is dead
2014-03-16T03:57:05 < dongs> it cannot be sold
2014-03-16T03:57:13 < nine-tails> look cisco routers
2014-03-16T03:57:37 < dongs> cisco started uysing lunix
2014-03-16T03:57:40 < dongs> so they're just as dead
2014-03-16T03:58:38 < nine-tails> first of all its gnu/linux
2014-03-16T03:58:45 < nine-tails> 2ndly i hate it also
2014-03-16T03:58:52 < nine-tails> i just hate windows more

2014-03-16T04:11:41 < emeb> tp: just so
2014-03-16T04:12:27 < tp> dongs, yeah everything that uses Linux is dead, just like Android is dead, WiFi and modems are dead, openvswitch and openflow are dead, etc etc
2014-03-16T04:12:47 < dongs> tp: yeah, wifi is dead.
2014-03-16T04:12:50 < tp> it's a shame that Android is so dead because they use Linux
2014-03-16T04:12:51 < dongs> i bought a fucking lunix-running wifi router
2014-03-16T04:13:06 < dongs> and my file copy speeds between wifiN laptop conected at 300mbps and my desktop are 300kiloBYTES/second
2014-03-16T04:13:14 < dongs> assdroid is fucking garbage
2014-03-16T04:13:17 < tp> oh and another shame that Nokia have ONE MILLION preorders in china for their Linux powered phone
2014-03-16T04:13:21 < dongs> 90% of why its garbage is exactly because its lunix
2014-03-16T04:13:51 < dongs> the other 10 is cuz its opensores
2014-03-16T04:13:52 < tp> yep, Samsung sells ONE MILLION Linux powered S series phones A DAY, because Linux is so dead
2014-03-16T04:14:08 < dongs> no, they sell it because its fucking free
2014-03-16T04:14:16 < tp> dongs, I don't benieve that 'dead' meand what you think it does ...
2014-03-16T04:14:22 < dongs> if they had to pay a license fee for a real OS for 1 million phoens a day, they wouldn't be selling as many
2014-03-16T04:14:43 < tp> who cares if Linux is Free, Samsung are crying themselves all the way to the bank
2014-03-16T04:15:01 < tp> dongs:  thank you for supporting my pro Linux argument

2014-03-16T04:15:32 < tp> sure, you just said it
2014-03-16T04:15:40 < dongs> except its not
2014-03-16T04:15:58 < tp> dongs:  I think you're one of Linux's best secret weapons
2014-03-16T04:16:05 < dongs> tehy are using lunix ONLY because its free
2014-03-16T04:16:18 < dongs> dealing with the fact that its utter and complete garbage
2014-03-16T04:16:29 < tp> exactly, as are thousands of other *successful* companies
2014-03-16T04:16:51 < dongs> if something proper comes out tomorrow that sucks 100x less, people will be like "whats luniox"?
2014-03-16T04:16:53 < tp> you drink water, which falls from the sky for free ?
2014-03-16T04:17:29 < tp> yeah and when that something that sucks 100x less, and is still free and open comes out, of course people will switch
2014-03-16T04:17:38 < tp> until then, we use Linux
2014-03-16T04:17:53 < dongs> enjoy shit.
2014-03-16T04:18:03 < tp> almost everyone here uses GNU/Linux
2014-03-16T04:18:21 < dongs> um, no.
2014-03-16T04:18:35 < dongs> just the freetards.
2014-03-16T04:19:05 < dongs> don't lump the real professionals into this "everyone uses lunix" shit
2014-03-16T04:19:24 < dongs> real pros use windows 8.1 PRO
2014-03-16T04:19:33 < tp> dongs:  listening to your rant about that old windows CAD Protel the last few days has been a good reminder to me that it hasn't changed much since I used it last, mainly the name to Atrium
2014-03-16T04:20:19 < tp> real professionals pay for their real CAD software dongs, you get your pirate copies for free, bitch and moan, then sing it's virtues
2014-03-16T04:20:46 < dongs> tp, i paid for my cad software.
2014-03-16T04:20:53 < dongs> i will pay for altium when it becomes more useful.
2014-03-16T04:21:04 < dongs> i do have a unlimited layer license for diptrace.
2014-03-16T04:21:12 < GargantuaSauce> jesus fuck why are we engaging in this conversation again
2014-03-16T04:21:20 < tp> Your anti Linux tirade is interesting to me, because under all that bitching and moaning, I see a sensible and capable person, so I still read what you say with interest
2014-03-16T04:21:25 < GargantuaSauce> you're both right, you're both wrong, all software is shit, use what you want
2014-03-16T04:21:39 < dongs> $7500 for sch/pcb with  90% of features I'll never use (FPGA, SPICE, etc) is not efficient spending of money.
2014-03-16T04:21:42 < tp> GargantuaSauce:  hahah, agree totally
2014-03-16T04:22:03 < tp> dongs:  I agree, Altium is overpriced windows crap
2014-03-16T04:22:12 < tp> Ill never use it (again)
2014-03-16T04:22:16 < dongs> it has nothing to do wiht the fact that it runs on windows
2014-03-16T04:22:19 < dongs> nothing serious runs on lunix
2014-03-16T04:22:21 < tp> and the last version I used was fully paid for
2014-03-16T04:22:26 < tp> hahahahahah
2014-03-16T04:22:28 < dongs> so adding "it runs on windows" is kinda dumb/pointless.
2014-03-16T04:23:08 < tp> nothing serious runs on Linux, sure, apart from Maya,Google,Android ...
2014-03-16T04:23:31 < tp> windows is white goods for the masses, it's crap, and we all know it
2014-03-16T04:23:43 < tp> even you know it dongs
2014-03-16T04:24:22 < dongs> why would any pro company spend their PAID developer time to make software for lunix, just so that freetards would spend years bitching that it's "not free" and demand free copies, when they can develop it on windows and make money instead?

2014-03-16T04:25:35 < tp> the only one I see bitching lately, is you dongs, youve had to wrestle with Atrium to do anything
2014-03-16T04:26:22 < tp> GargantuaSauce:  maybe, in event, dongs is the most capable troll I've seen in a long time. He actually makes stuff, and I respect that
2014-03-16T04:26:47 < dongs> http://i.imgur.com/XkJQMwO.png i ended up with this last night w/altium
2014-03-16T04:26:53 < dongs> need to figure out how to do copper pours and i might be done
2014-03-16T04:27:28 < tp> nice work dongs!
2014-03-16T04:30:34 < dongs> multirouting is pretty awesome, as well as drag/push route stuff.
2014-03-16T04:30:53 < tp> here is a photo of one of my home made pcbs, using only Linux apps: http://www.portertech.org/test/pcb/fb02-pcb-dimension.jpg
2014-03-16T04:30:53 < GargantuaSauce> do you still prefer dicktrace overall?
2014-03-16T04:31:49 < dongs> GargantuaSauce: maybe for quick stuff, but i think from now im gonna try moving a few projects to altium.
2014-03-16T04:31:57 < dongs> one of htem will need to be altium anyway due to 4l and too many tracesw
2014-03-16T04:32:21 < dongs> which was the reason i started setting it up
2014-03-16T04:33:09 < dongs> tp: i dont have t ime to dick wiht etching dip pcbs.
2014-03-16T04:33:20 < dongs> i can get boards in 48 hours if i really need them.
2014-03-16T04:34:08 < tp> dongs:  definitely, but I made that in 1996, and here in Australia, we don't get anything quickly
2014-03-16T04:34:22 < dongs> i can only imagine the state of lunix pcb cad in1996
2014-03-16T04:34:25 < dongs> sorry to hear that.
2014-03-16T04:34:52 < dongs> tho, its probably not THAT much better in 2014.
2014-03-16T04:35:01 < GargantuaSauce> i couldnt handle kicad at all
2014-03-16T04:35:05 < tp> you just saw the state of Linux pcb CAD in 1996, it was fine, way better imho than protel (Altium) was then
2014-03-16T04:35:28 < tp> dongs:  ever used Orcad (DOS) ?
2014-03-16T04:35:43 < tp> GargantuaSauce:  same, I don't like or use Kicad
2014-03-16T04:36:03 < GargantuaSauce> whats the name of the russian-made pcb cad that makes weird curvy traces? been meaning to try that
2014-03-16T04:36:10 < cosm0naut> topor

2014-03-16T04:36:28 < cosm0naut> it's only a trace router though, right?

2014-03-16T04:39:13 < dongs> insane rather
2014-03-16T04:39:28 < tp> this is a example of a complex pcb made by the Linux pcb CAD I use : http://www.delorie.com/electronics/rx/os-board-1x.jpg
2014-03-16T04:39:53 < cosm0naut> tp: which program?
2014-03-16T04:39:54 < dongs> yeah, delorie is the only gEDA user that still uses it
2014-03-16T04:39:58 < dongs> cosm0naut: its geda
2014-03-16T04:40:28 < tp> dongs:  times have changed, there are a number of component design support utils for gEDA
2014-03-16T04:40:43 < tp> cosm0naut:  thats gEDA "PCB"
2014-03-16T04:41:27 < tp> PCB was originally designed by Thomas Nau in the 90's as his thesis I think, it eventually eneded up under the gEDA banner
2014-03-16T04:41:42 < dongs> tp: doesnt matter, cant change the fact that djd is a cunt and he's singlehandedly killing that project (which is doing a good job killing itself even without his help)
2014-03-16T04:42:37 < tp> cosm0naut:  here is the schematic capture of that PCB above, it's called 'gSchem' : http://www.delorie.com/electronics/rx/os-board-sch.pdf
2014-03-16T04:42:49 < tp> dongs:  you're totally wrong
2014-03-16T04:42:50 < dongs> those colors
2014-03-16T04:43:01 < dongs> how do i contrasted
2014-03-16T04:43:22 < tp> Dj Delorie released the first GCC port for windows way back, called DJGPP
2014-03-16T04:44:00 < dongs> oh i forgot, most lunix dweebs are probably looking at that shit through a 16color mono amber monitor
2014-03-16T04:44:02 < tp> it was free, and the *only* flawless C compiler I could find for free for windows way back then
2014-03-16T04:44:19 < dongs> haha, gcc, flawless.
2014-03-16T04:44:41 < tp> yeah, thats right, I Im using windows 3.1 and a EGA monitor
2014-03-16T04:45:30 < dongs> im not surprised.
2014-03-16T04:46:12 < tp> it was compared to the 'shareware' or payware windows 3.1 C compilers back around 1991
2014-03-16T04:47:13 < dongs> sorry, borland turbo C absolutely raped gcc or dgpp or whatever other trash
2014-03-16T04:47:23 < talsit> HAHAHAHAHAHAAAAAAA
2014-03-16T04:47:31 < talsit> good one dongs...
2014-03-16T04:47:48 < cosm0naut> man, we are getting down to the nitty gritty, compiler battles...
2014-03-16T04:47:54 < talsit> i needed a good sunday laugh
2014-03-16T04:48:18 < tp> dongs:  I sent DJDelorie $100 last year, and $100, four years before that. In another 4 years, I'll send him another $100 USD ... thats how much of a cunt I think he is
2014-03-16T04:49:00 < tp> I paid for Borland Turbo C, but never took to it
2014-03-16T04:50:05 < zyp> I remember DJGPP had awesome support for C++11
2014-03-16T04:50:26 < dongs> wut
2014-03-16T04:50:59 < tp> in fact, it was when I used DJGPP on windows, that I started thinking, "if this is a port of something that runs on Linux, maybe it will be even better if I run Linux?". So DJDelorie was actually the reason I 'discovered' Linux in the first place, so I send him $100 USD every 5 years as a thank you
2014-03-16T04:52:23 < dongs> cool story bro
2014-03-16T04:52:28 < dongs> lunix still sucks tho
2014-03-16T04:52:31 < tp> for any BSD people here, I also really like the BSD's
2014-03-16T04:52:56 < GargantuaSauce> heheh waaaait for it
2014-03-16T04:53:24 < tp> hahah, no worries dongs, excellent pcb you have done, especially considering it was with that slow as molasses Altium
2014-03-16T04:53:41 < zyp> slow as molasses? :D
2014-03-16T04:53:50 < tp> sure
2014-03-16T04:53:54 < dongs> bsd people.. so you're addressing a bunch of rotting corpses?
2014-03-16T04:54:01 < tp> panning is painfully slow, ask dongs ?
2014-03-16T04:54:59 < tp> it was when it was called 'Protel', so I wasnt suprised to hear it is still slow when panning ... unless of course dongs has a lame all back of the bus PC ?
2014-03-16T04:55:04 < zyp> can't say I have that problem
2014-03-16T04:55:15 < zyp> but then again I've got a fairly modern computer
2014-03-16T04:55:41 < tp> or maybe dongs pirated windows is too busy emailing spam from viruses to give much cpu to Altium ?
2014-03-16T04:55:49 < zyp> although I don't remember it being particularly slow on the shitty work computer I've also used it on
2014-03-16T04:56:08 < dongs> make a3 schematic and select all and try to drag it
2014-03-16T04:56:10 < zyp> but that might be because everything else also is slow on that computer
2014-03-16T04:56:14 < dongs> you can see it redrawing every component
2014-03-16T04:56:16 < tp> zyp:  what kind of machine do you run protel on ?
2014-03-16T04:56:27 < dongs> pcb is fine
2014-03-16T04:56:40 < tp> dongs:  yep, it's *really* painful as I recall
2014-03-16T04:57:01 < tp> zyp:  sorry I meant Altium
2014-03-16T04:57:24 < zyp> kind?
2014-03-16T04:57:32 < zyp> the cpu is a 3770K
2014-03-16T04:57:44 < tp> ahh ok, modern cpu
2014-03-16T04:58:02 < talsit> i'm on a laptop
2014-03-16T04:58:04 < zyp> well, of course, it's a modern computer

2014-03-16T04:58:18 < dongs> so also not terrible
2014-03-16T04:58:23 < dongs> but its definintely not cpu bound there
2014-03-16T04:58:24 < talsit> i7-2860
2014-03-16T04:58:34 < dongs> schematic provbably still uses GDI for drawing shit
2014-03-16T04:58:48 < dongs> its nowhere as terrible as shit like orcad or cam350
2014-03-16T04:58:51 < zyp> I don't use shitty computers and expect them to perform like nonshitty computers, because I know they won't and I prefer to avoid that
2014-03-16T04:58:59 < tp> for anyone who actually believes that gEDA cant make a decent pcb, have a look at this link I posted earlier : http://www.delorie.com/electronics/rx/os-board.html
2014-03-16T04:59:12 < zyp> so what?
2014-03-16T04:59:12 < tp> zyp:  sure, same here
2014-03-16T04:59:48 < zyp> I've done a 256bga design in eagle, doesn't mean I don't rather prefer altium
2014-03-16T04:59:50 < tp> dongs:  you mean windows orcad, or windows cam350
2014-03-16T04:59:58 < dongs> bothg
2014-03-16T05:00:24 < tp> eagle and altium have something in common, both payware
2014-03-16T05:00:34 < tp> I don't like eagle myself
2014-03-16T05:00:36 < zyp> true
2014-03-16T05:01:10 < tp> I've been using gschem (gEDA) and PCB (gEDA) for so long I don;t want anything else
2014-03-16T05:01:15 < zyp> and I can use both legally
2014-03-16T05:01:27 < zyp> I bought eagle, work bought altium
2014-03-16T05:01:29 < tp> zyp:   you're a rich man ;-)

2014-03-16T05:02:02 < tp> yeah eagle isnt that expensive, but Altium is just rediculous
2014-03-16T05:02:48 < tp> when Altium was Protel (created in Tasmania) back in the 90's, it cost $5000 AUD for the schematic cap, and another $5000 for the pcb cad
2014-03-16T05:03:08 < upgrdman> tp: ever find an easy way to thermal a pad (not a hole) to a ground fill in pcb?
2014-03-16T05:03:18 < upgrdman> other than manually drawing traces
2014-03-16T05:03:25 < tp> it was slow as a dog back then on the old windows machines we all had, (modern at the time)

2014-03-16T05:04:29 < tp> zyp:  they seemed fast 'at the time' :)
2014-03-16T05:04:51 < tp> zyp, I have just pasted two links of PCB boards
2014-03-16T05:05:01 < zyp> I remember looking at pcb once, it seemed about as usable for designing boards as mspaint
2014-03-16T05:05:10 < dongs> haha
2014-03-16T05:05:42 < tp> zyp:  do you have a problem viewing links here ?
2014-03-16T05:05:45 < zyp> and when I actually consider eagle a sort of decent tool, that's saying something
2014-03-16T05:05:47 < upgrdman> zyp: i use pcb. and, well, there's lots of room for improvement :)
2014-03-16T05:06:24 < zyp> tp, no, but I'd bet you could find somebody crazy enough to draw something like that in mspaint as well :)
2014-03-16T05:06:27 < upgrdman> tp: people can make awesome paintings with ms paint too. but that doesn't mean ms paint is a good tool for high end stuff.
2014-03-16T05:06:32 < tp> upgrdman:  have any speed problems panning A3 sized PCB's on PCB ?
2014-03-16T05:06:56 < upgrdman> tp: i dont know what a3 size is, but my pcb's arent very big or complicated.
2014-03-16T05:07:07 < upgrdman> i etch 1L pcb's at home.
2014-03-16T05:07:18 < upgrdman> the butt of many jokes in here :)
2014-03-16T05:07:32 < tp> I'm not claiming that pcb or gEDA is 'high end' but it's good enough for what Dongs did with Altium and pasted here

2014-03-16T05:12:55 < zyp> that looks pretty nice for being home-etched
2014-03-16T05:13:02 < upgrdman> zyp: thanks.
2014-03-16T05:13:15 < tp> upgrdman:  laser printer for the artwork ?

2014-03-16T05:15:13 < upgrdman> GargantuaSauce: never broken one, or ripped a trace. and it was in my robot with leads attached and always falling over
2014-03-16T05:15:24 < GargantuaSauce> wow, cool
2014-03-16T05:15:29 < upgrdman> like this  http://farrellf.com/temp/robot_pre_pcb.jpg
2014-03-16T05:15:50 < GargantuaSauce> i am going to be drawing heavily on your materials when i finally get around to finishing my designs
2014-03-16T05:16:02 < upgrdman> cool
2014-03-16T05:16:16 < tp> upgrdman:  you printed the artwork from PCB onto a transparency with a laser printer, correct ?
2014-03-16T05:16:32 < upgrdman> yes. 600dpi required.
2014-03-16T05:17:01 < tp> I mention it because I use "drafting film", two prints overlaid, to stop pinholes
2014-03-16T05:17:31 < tp> from the laser, and all lasers have random pinholes in the printed artwork
2014-03-16T05:17:56 < tp> the drafting film is ground, so I don't get any slippage as I get with OHT film
2014-03-16T05:18:24 < tp> other than that, my process is the same as yours
2014-03-16T05:18:35 < zyp> done any double sided boards?
2014-03-16T05:18:39 < upgrdman> not sure if my printer is just awesome, or what, but toner coverage hasnt been a problem for me
2014-03-16T05:18:55 < tp> no, tho thats not too hard, apart from a lack of PTH
2014-03-16T05:19:01 < upgrdman> zyp: no. im too lazy to drill. i might later on through
2014-03-16T05:19:36 < tp> zyp:  single sided only pcbs will hone your layout skills ;-)
2014-03-16T05:19:39 < zyp> I've done a couple, and yes, drilling is pain :p
2014-03-16T05:19:58 < zyp> tp, and also fuck up your signal integrity
2014-03-16T05:20:05 < upgrdman> for example, heres a 6mil trace sneaking through some pads. the other traces are 10mil: http://farrellf.com/temp/pcb_macros/IMG_4389.JPG
2014-03-16T05:20:14 < upgrdman> consistent quality
2014-03-16T05:21:51 < tp> yep, 6mil is definitely doable and consistent. I do 10mil and could go to 4 I think

2014-03-16T05:33:32 < tp> and thats a pretty common reason for everyone
2014-03-16T05:34:12 < tp> mac users usually use MAC for the medium range video or audio software
2014-03-16T05:35:02 < zyp> funny you should mention that, I use OS X because it provides said cli environment windows lacks
2014-03-16T05:35:17 < tp> the big deal for me is that the tech world is changing very fast, Linux is often at the front edge of that change

2014-03-16T05:38:53 < zyp> nothing is perfect, it's all a matter of needs, priorities and compromises

2014-03-16T05:41:20 < tp> thats news to me
2014-03-16T05:41:22 < GargantuaSauce> X is definitely shitty
2014-03-16T05:41:51 < GargantuaSauce> holding out for wayland.
2014-03-16T05:42:06 < zyp> I'm not pointing at X, I'm talking about how useless and shitty everything feels when I'm trying to use stuff and get anything done
2014-03-16T05:42:16 < tp> Im using it right now with Xchat, from a pc,running remote X on a openvz container on my server, seems ok to me
2014-03-16T05:43:02 < tp> everything I run is on a OpenVZ or Docker container, all use remote X
2014-03-16T05:43:18 < tp> all are a menu click away
2014-03-16T05:44:01 < tp> they all use passwordless pub key openssh to transport the X stream
2014-03-16T05:44:47 < zyp> I'm running linux on my primary work computer, and anything GUI related feels unstable and/or badly designed compared to both windows and os x

2014-03-16T05:46:00 < zyp> gnome-panel shitting itself seems to be a recurring issue, for instance
2014-03-16T05:46:13 < dongs> zyp, yo're supposed to use KDE because its more amazingly awesome
2014-03-16T05:46:14 < GargantuaSauce> i quite like where kde has gone in the last little while
2014-03-16T05:46:19 < GargantuaSauce> not that it doesn't have its warts
2014-03-16T05:46:28 < dongs> all that fucking effort
2014-03-16T05:46:30 < GargantuaSauce> but it certainly pisses me off less than gnome
2014-03-16T05:46:32 < dongs> wasted doing same fucking shit
2014-03-16T05:46:32 < zyp> I'll admit, I haven't tried KDE recently
2014-03-16T05:46:39 < dongs> thats the problem with lunix
2014-03-16T05:46:45 < dongs> maybe if they'd all focus on making lunix less shit

2014-03-16T05:46:54 < dongs> until then it remains a waste of time
2014-03-16T05:48:49 < tp> I don't use the KDE gui
2014-03-16T05:49:06 < tp> I sure use apps that run the QT libraries tho
2014-03-16T05:49:13 < zyp> I can do other examples as well; gnome's pdf reader evince is shit (albeit the least shitty pdf reader I've tried on linux so far)
2014-03-16T05:49:30 < GargantuaSauce> yeah plasma is perhaps the worst part of kde
2014-03-16T05:49:35 < tp> zyp:  there is acrobat for Linux
2014-03-16T05:49:48 < GargantuaSauce> i quite like okular
2014-03-16T05:49:54 < zyp> every time I'm scrolling to a new section in the text that has a TOC entry, it insists on expanding the entire TOC tree down to that node so it can be highlighted
2014-03-16T05:49:54 < tp> but I usually use "gv" for small PDF's
2014-03-16T05:50:17 < zyp> which is fucking annoying when I'm reading a reference manual of a couple thousand pages and skipping through some chapters
2014-03-16T05:50:21 < tp> GargantuaSauce:  no shortage of PDF apps with Linux
2014-03-16T05:50:29 < zyp> because then I have to go back and close the toc nodes afterwards
2014-03-16T05:50:33 < tp> eww\
2014-03-16T05:50:55 < zyp> I haven't seen any linux pdf readers that handles tocs in a sane way
2014-03-16T05:50:59 < tp> zyp:  have you used acrobat on Linux ?
2014-03-16T05:51:24 < zyp> maybe, long ago

2014-03-16T05:53:05 < zyp> theming is also a recurring issue
2014-03-16T05:53:13 < zyp> with all the different gui toolkits and shit

2014-03-16T05:53:54 < zyp> bloat in what sense?
2014-03-16T05:54:00 < tp> I don't want anything slowing me down, hence Im no fan of bling
2014-03-16T05:54:06 < tp> slow, blingy
2014-03-16T05:54:46 < tp> compiz, etc, rotating cubes with apps running on every face ...
2014-03-16T05:54:56 < zyp> I have a modern computer so I don't give a fuck about resource usage (within reasonable terms, of course)
2014-03-16T05:54:57 < GargantuaSauce> well if all you do is remote stuff then of course anything that is made for a compositor will be slow as balls
2014-03-16T05:55:00 < tp> windows that burn down when killed
2014-03-16T05:55:20 < zyp> what I care about is stuff that have the functions I want and that they actually work
2014-03-16T05:55:26 < tp> same
2014-03-16T05:56:21 < zyp> I hate minimaslistic window managers for that reason, like those *box-things that used to be all the rage
2014-03-16T05:56:38 < tp> GargantuaSauce:  my workstation is 32Gb i7 with nvidia gtx660 (think), but I still hate bling
2014-03-16T05:57:21 < zyp> I hate stuff that distracts
2014-03-16T05:57:27 < tp> zyp:  same, icewm is simple, but not minimalistic
2014-03-16T05:57:36 < tp> same
2014-03-16T05:58:47 < tp> I'd normally be working right now, but I've pulled a muscle down the gym, so taking the day easy today
2014-03-16T05:58:47 < zyp> I don't really give a fuck about a bunch of the fancy stuff in OS X, but the nice part about OS X is that it's fairly well moderated, I don't find it distracting
2014-03-16T05:59:12 < zyp> and that expose-thing for switching windows is pretty useful
2014-03-16T05:59:40 < GargantuaSauce> kde has that and i love it. basically the only fancy kwm feature i use

2014-03-16T06:00:09 < tp> I agree with you guys about one Linux annoyance, Linux is very fragmented, and that can be annoying, but I think that is part of Linux, it will always be evolving rapidly
2014-03-16T06:00:22 < GargantuaSauce> i think it is an advantage as well as a disadvantage
2014-03-16T06:00:28 < tp> GargantuaSauce:  agree
2014-03-16T06:00:30 < GargantuaSauce> sure it splits the workforce, but competition is a good thing
2014-03-16T06:00:35 < zyp> I also agree
2014-03-16T06:00:38 < GargantuaSauce> because the alternative is stagnation
2014-03-16T06:00:46 < tp> competition is probably the (only* thing
2014-03-16T06:01:22 < tp> it's like nature, the weak and slow to adapt shrivel up and die in time
2014-03-16T06:02:08 < tp> I've been using Linux (only) the last 14 years, and Ive had to adapt to many changes, which can be very annoying as I hate change
2014-03-16T06:02:42 < tp> I had no sooner mastered the LILO bootloader, than along came GRUB, then GRUB2 etc

2014-03-16T06:03:33 < zyp> I'd say if you're using one OS exclusively, you're not really in a position to do a fair comparison with the alternatives :)

2014-03-16T06:04:13 < zyp> of course everything is wrong when it's different from what you're used to

2014-03-16T06:04:46 < tp> zyp:  it's a lot easier to avoid Linux on the desktop than windows
2014-03-16T06:04:46 < GargantuaSauce> what chipset does it use?
2014-03-16T06:04:54 < dongs> GargantuaSauce: see, i dont need to care.
2014-03-16T06:05:00 < dongs> but I suspect displaylink
2014-03-16T06:05:05 < zyp> tp, also true
2014-03-16T06:05:49 < zyp> main reason I'm running linux at work is that OS X is not an option
2014-03-16T06:05:51 < dongs> http://www.ebay.com/itm/161049835838 it was the cheapest shit listed
2014-03-16T06:06:09 < zyp> because linux on the desktop doesn't really do much that OS X can't do better

2014-03-16T06:07:42 < zyp> I prefer to call it «a working gui»
2014-03-16T06:08:01 < zyp> because I prefer looking at the advantages :)
2014-03-16T06:08:04 < tp> I know OSX users love it
2014-03-16T06:09:24 < tp> my GUI needs are simple, a menu I can edit, xterm, 28 virtual desktops, system monitor and backgrounds I can change, is about it
2014-03-16T06:10:07 < dongs> i can afford monitors.. so i dont need "virtual" desktops
2014-03-16T06:10:26 < dongs> the whole concept of virtual desktop was made by lunix dweebs
2014-03-16T06:10:34 < dongs> since multiple v ideo cards/mnonitors never worked properly in lunix
2014-03-16T06:10:53 < dongs> i remember in like 1999 i got a old dekstop
2014-03-16T06:10:58 < dongs> and plugged in a 2nd pci video carrrd
2014-03-16T06:11:02 < dongs> win98SE instantly recognized it
2014-03-16T06:11:04 < zyp> OS X also have virtual desktops, but I never really figured out how to use them properly
2014-03-16T06:11:07 < dongs> and i could drag windows from one monitor to another
2014-03-16T06:11:33 < tp> zyp:  here is a line from my menu whicg runs gschem: prog "GSCHEM DESIGN" - ssh -Y tp@192.168.0.62 gschem
2014-03-16T06:11:52 < dongs> youre using pcb over netwrok X?

2014-03-16T06:12:04 < dongs> now on
2014-03-16T06:12:15 < tp> so  click on the gschem menu, and up pops the gui schematic editor, running on a openvz instance on the server
2014-03-16T06:13:06 < tp> dongs:  it distresses me to know that you're intelligent enough to understand that menu line, and also hate Linux ;-)
2014-03-16T06:13:18 < zyp> tp, my shortcut for starting altium is something like win+5, I'd say it's arguably easier

2014-03-16T06:13:46 < zyp> no, why would I?

2014-03-16T06:14:04 < tp> zyp:  thats why your menu is easier
2014-03-16T06:14:43 < zyp> I'm not really fan of menus at all, I prefer using the keyboard
2014-03-16T06:14:45 < tp> zyp:  if I ran gschem locally the menu would read " prog "GSCHEM DESIGN" - gschem "

2014-03-16T06:16:47 < zyp> tp, you say «a menu I can edit», I'd call that «a menu I have to edit»
2014-03-16T06:16:59 < tp> it's all click n grunt here, just like windows
2014-03-16T06:17:14 < tp> pedantic dudes ...
2014-03-16T06:17:19 < zyp> yes, but I don't prefer windows, remember
2014-03-16T06:17:38 < tp> I edited it *once* about 2 years ago, clicked thereafter
2014-03-16T06:17:53 < zyp> what I like is being able to hit ctrl-space, type in the first couple of characters of something's name and hit enter
2014-03-16T06:18:10 < tp> zyp:  no one prefers windows, they get windows thrust upon them usually
2014-03-16T06:18:12 < zyp> because that's way faster than searching for anything in a graphical menu
2014-03-16T06:18:14 < dongs> is that the sherlock trash?
2014-03-16T06:18:21 < dongs> cuz you can hit winkey and type stuff and have sameeffect
2014-03-16T06:18:31 < zyp> I know
2014-03-16T06:18:57 < zyp> does when windows equivalent only find programs, or does it find any kind of document?
2014-03-16T06:19:11 < GargantuaSauce> every modern DE has exactly that
2014-03-16T06:19:12 < tp> dongs:  wrong! when I hit the winkey, I get my Linux menu :P
2014-03-16T06:19:14 < zyp> I open chip datasheets in the same way
2014-03-16T06:19:36 < dongs> zyp: i dunno, i organize stuff by project
2014-03-16T06:20:01 < dongs> yes apparently does file stoo
2014-03-16T06:20:14 < zyp> I don't want to spend time organizing, I prefer to just have all the thrash I've downloaded some time indexed
2014-03-16T06:20:32 < dongs> sux 4 u
2014-03-16T06:20:36 < tp> zyp:  if you have heapos of datasheets and notes etc, I suggest 'recoll' as a db for indexing everything
2014-03-16T06:20:39 < dongs> i bet macos is great for you tehn
2014-03-16T06:20:44 < dongs> just everythign in y our home folder
2014-03-16T06:20:45 < dongs> 10000 files
2014-03-16T06:21:04 < zyp> tp, I don't need that, OS X already does an excellent job of it
2014-03-16T06:21:07 < tp> dongs:  you know  OSX ?
2014-03-16T06:21:33 < tp> zyp:  what does it use for indexing ?
2014-03-16T06:21:35 < zyp> dongs, it's mostly in «Downloads», not the home folder itself

2014-03-16T06:22:27 < zyp> I don't know how it works, and as long as it does I don't really care either
2014-03-16T06:22:49 < tp> not that there is anything wrong with being gay ...
2014-03-16T06:26:11 < tp> zyp:  does spotlight index pdf contents ?
2014-03-16T06:26:15 < zyp> yes
2014-03-16T06:26:18 < tp> cool
2014-03-16T06:28:17 < zyp> and the search results shows a preview of the document when I navigate through the list, so I can just search for a stm32 variant and it usually comes up with the datasheet and RM and possibly a couple of other related documents
2014-03-16T06:28:25 < tp> zyp will spotlight index a MS-Word document stored as an attachment to an e-mail message inside a Thunderbird folder archived in a Zip file ? ... recoll will :)
2014-03-16T06:28:50 < zyp> I don't know and I don't care :)
2014-03-16T06:29:06 < tp> zyp:  cool, thats the kind of stuff I do here
2014-03-16T06:29:35 < zyp> I'm using gmail for mail, and gmail has it's own attachment indexing
2014-03-16T06:30:11 < tp> same, but it wont search pdf attachment contents as far as I know
2014-03-16T06:30:17 < zyp> sure it does
2014-03-16T06:30:25 < tp> oh, I didnt know that
2014-03-16T06:30:49 < tp> my Gmail FU is low
2014-03-16T06:32:16 < zyp> I did that the other day, searching for «digi key micro usb», and it found the mail i was looking for which had an attached invoice of an order that included micro usb sockets
2014-03-16T06:34:22 < tp> nice
2014-03-16T06:38:09 < dongs> yeah, gmail indexing is fine
2014-03-16T06:39:39 < zyp> anyway, my original argument was about starting applications, because that's how I usually do it, since it's faster than looking through menus

2014-03-16T06:48:23 < zyp> emeb_mac, sdr board that goes on top of the bcc?
2014-03-16T06:48:29 < emeb_mac> zyp: yes
2014-03-16T06:48:38 < tp> madist:  awesome
2014-03-16T06:48:39 < zyp> which freqs? both tx and rx?
2014-03-16T06:49:03 < emeb_mac> two bands - 0-30MHz and 50-1000MHz
2014-03-16T06:49:13 < emeb_mac> tx and rx
2014-03-16T06:49:22 < emeb_mac> can be separate freqs too
2014-03-16T06:49:36 < zyp> what's those funny looking footprints for U203 and U205?
2014-03-16T06:50:00 < tp> emeb_mac:  you rule dude, thats one beautiful board
2014-03-16T06:50:27 < emeb_mac> zyp: those are mini-circuits RF amps

2014-03-16T06:53:24 < tp> gee, the pcb is just a *part* of it
2014-03-16T06:53:30 < emeb_mac> goes from RF to bits. hooks to an FPGA where the bits are massaged w/ DSP
2014-03-16T06:53:44  * GargantuaSauce massages emeb_mac's bits
2014-03-16T06:53:49 < emeb_mac> and the FPGA hooks to a Beaglebone where you do whatever you want with the results
2014-03-16T06:53:54 < tp> emeb_mac:  what kind of radio ?
2014-03-16T06:54:01 < tp> SS ?
2014-03-16T06:54:06 < emeb_mac> tp: sdr - anything you want. :)
2014-03-16T06:54:07 < tp> FM, AM, ?

2014-03-16T06:54:22 < emeb_mac> englishman: yeah.
2014-03-16T06:54:26 < englishman> :(
2014-03-16T06:54:30 < emeb_mac> gotta renew mine this year
2014-03-16T06:54:49 < GargantuaSauce> i am getting mine in a couple weeks
2014-03-16T06:55:12 < englishman> good for you :)
2014-03-16T06:55:17 < GargantuaSauce> :)
2014-03-16T06:55:20 < englishman> just basic GargantuaSauce?
2014-03-16T06:55:43 < tp> emeb_mac:  I have a WiFi business (resell SS radio gear) but havent come across SDR, that's gotta be sending the 'authorities' into a frenzy ?
2014-03-16T06:56:04 < zyp> tp, sdr devices just grab a piece of spectrum and pipes it into/out of software, so you can do whatever modulation you want in software, provided it fits in the spectrum bandwidth
2014-03-16T06:56:06 < englishman> how so?
2014-03-16T06:56:09 < zyp> to put it simply
2014-03-16T06:56:14 < GargantuaSauce> think there's only one 'level' in canada
2014-03-16T06:56:19 < englishman> basic and advanced
2014-03-16T06:56:25 < zyp> illegal sdr usage is no different from other illegal radio transmission
2014-03-16T06:56:34 < emeb_mac> tp: I don't know that there's any issues with the regulatory authorities
2014-03-16T06:56:40 < tp> zyp:  thanks for that concise explanation :)
2014-03-16T06:56:44 < englishman> advanced = bump to 1500W, can build your own transmitters
2014-03-16T06:56:47 < emeb_mac> no worse than any DIY radio stuff at least
2014-03-16T06:56:55 < tp> emeb_mac:  oh, it's only a receiver ?
2014-03-16T06:56:57 < GargantuaSauce> oh right
2014-03-16T06:57:03 < emeb_mac> tp: it has TX too
2014-03-16T06:57:10 < GargantuaSauce> my examiner is a colleague, he'll probably push me to go right to advanced
2014-03-16T06:57:15 < tp> ahh, thats what I meant then
2014-03-16T06:57:24 < emeb_mac> +20dBm out - needs a PA if you want more.
2014-03-16T06:57:28 < englishman> advanced is easier from what i hear, more tech stuff and less law stuff
2014-03-16T06:57:32 < englishman> but i haven't even looked.
2014-03-16T06:57:38 < GargantuaSauce> only downside is i won't be able to plead ignorance about breaking rf regulations :(
2014-03-16T06:58:04 < emeb_mac> like pleading ignorance ever works
2014-03-16T06:58:04 < zyp> I've also considered getting a license
2014-03-16T06:58:51 < tp> <zyp> illegal sdr usage is no different from other illegal radio transmission ... very true, which also applies to firearms, but look at the reaction the '3d printed handgun' caused ?
2014-03-16T06:59:01 < englishman> media reaction
2014-03-16T06:59:05 < emeb_mac> that
2014-03-16T06:59:12 < zyp> did it cause much reaction apart from headlines?
2014-03-16T06:59:12 < tp> authorities also
2014-03-16T06:59:13 < emeb_mac> ehrmagerhd!
2014-03-16T06:59:13 < GargantuaSauce> the amazing self-disassembling weapon
2014-03-16T06:59:31 < englishman> oh no firearms that are more expensive and less useful than real firearms
2014-03-16T06:59:36 < emeb_mac> :)

2014-03-16T07:00:26 < emeb_mac> tp: indeed.

2014-03-16T07:01:07 < zyp> SDR can legally be used within unlicenced bands, so there's nothing inherently illegal with the SDR device itself

2014-03-16T07:01:11 < tp> emeb_mac:  and the fact that some of the gear we sell can be reconfigured by the customer to operate outside au specs, sends the ACMA int fits
2014-03-16T07:01:23 < emeb_mac> I'll bet.

2014-03-16T07:12:32 < zippe> It's not the "inherent limitations"
2014-03-16T07:12:34 < GargantuaSauce> i tried flashing my reprap last weekend and had to go through 3 arduino ide versions
2014-03-16T07:12:44 < zippe> It's just that they just all don't work

2014-03-16T07:13:02 < GargantuaSauce> 2 had broken gcc distros and none of them would actually work with the damn bootloader, nor invoke avrdude properly
2014-03-16T07:13:03 < zippe> e.g. the Pinguino IDE … you can't even type in it without it corrupting what you type
2014-03-16T07:13:07 < tp> emeb_mac:  brilliant, glad to hear it
2014-03-16T07:13:18 < emeb_mac> I've got a script that takes pcb output and massages the names & drills for OSHpark tho
2014-03-16T07:13:19 < zippe> and when you finally get something compiled, the uploader spews errors
2014-03-16T07:13:35 < tp> emeb_mac:  ahhh
2014-03-16T07:13:35 < zippe> and then you discover that you can't switch a pin back from serial to GPIO so you can't send a break anyway
2014-03-16T07:13:51 < GargantuaSauce> the key is to add the undocumented config option to not delete the built sketch from /tmp
2014-03-16T07:13:57 < GargantuaSauce> and then flash manually
2014-03-16T07:14:06 < zippe> That's after it turns out that one of the two boards I tried doesn't actually have a serial port in the first place

2014-03-16T07:36:49 < zippe> Is it a program?
2014-03-16T07:36:55 < zippe> Is it a build system?

2014-03-16T07:43:41 < zippe> Not because I hate python - I am starting to get a grip on it and so far apart from being dog slow I quite like it. It's just not helpful to be wondering whether something is a dictionary or a method call or a list when I'm trying to make the build system go.

2014-03-16T07:45:02 < emeb_mac> just do it all in shell scripts
2014-03-16T07:45:10 < zyp> zippe, http://cgit.jvnv.net/arcin/tree/SConstruct <- this is a better example of simple stuff
2014-03-16T07:45:27 < zippe> ds2: Conceptually, I like CMake. A pity that in the flesh it is a gangrenous wound.
2014-03-16T07:45:45 < ds2> I see
2014-03-16T07:45:52 < ds2> cmake is a total and complete abomination.
2014-03-16T07:45:59 < ds2> wouldn't touch that with a 200meter pole
2014-03-16T07:46:19 < ds2> what I don't like about scons is you can stick any python shit in there
2014-03-16T07:46:21 < jpa-> cmake works surprisingly well considering how stupid the concept is..
2014-03-16T07:46:24 < zippe> ds2: the problem with cmake, for me, is that I can get about 90% of the way to a good result with very little effort
2014-03-16T07:46:32 < zippe> ds2: the last 10% … well
2014-03-16T07:46:37 < zyp> ds2, coincidentially that's what I like about it
2014-03-16T07:47:05 < zippe> ds2: I wrote a kconfig parser in CMake a while back… it was amusing, but not something I would accept money to maintain
2014-03-16T07:47:07 < ds2> zyp: if you are disciplined about it, that's good... otherwise, it invites all sorts of nasty stuff to be shoved in there
2014-03-16T07:47:20 < jpa-> ds2: you can stick any python shit in makefiles also, just prefix with "python -c" :)
2014-03-16T07:47:26 < ds2> zippe: I don't see the point of having a system that just writes makefiles
2014-03-16T07:47:38 < zippe> ds2: in the end, I fall back to make. It's like buying beer at the supermarket.
2014-03-16T07:47:40 < ds2> zippe: that pos insists on hard coding paths left and right. makes things totally unportable
2014-03-16T07:48:02 < ds2> jpa-: yes but that is more obvious
2014-03-16T07:48:07 < zippe> ds2: the idea, and please don't assume I'm defending it, is that that's an implementation detail. Mostly I use cmake -> ninja
2014-03-16T07:48:16 < ds2> sconstruct files look like python
2014-03-16T07:48:20 < zyp> ds2, running custom python code inside scons to create rules isn't any worse than running custom python code to generate a makefile with rules IMO
2014-03-16T07:48:39 < ds2> zippe: it is just bad progression... autoconf... libtools...now cmake
2014-03-16T07:48:44 < zippe> It's the "running inscrutable custom python code" that upsets me…
2014-03-16T07:49:04 < zyp> and I like avoiding the step of going through another textual representation
2014-03-16T07:49:08 < ds2> zyp: no, that's not what i am complaining about. what I am complaining about is adding code thatreally isn't build related in there

2014-03-16T07:49:26 < zippe> Then again, my habit of deconstructing the target name to parameterise sub-make invocations is probably no better
2014-03-16T07:49:40 < zippe> Is waf any better?
2014-03-16T07:49:51 < zippe> from a 'clean' perspective?
2014-03-16T07:50:04 < ds2> stop hiding thigns in other things
2014-03-16T07:50:06 < zyp> was that a scons fork, or how was it?
2014-03-16T07:50:24 < zyp> I remember reading about it, but I don't remember what I read
2014-03-16T07:50:28 < zippe> It may have been once. I read their manifesto a while back and Tridge speaks quite highly of it

2014-03-16T07:50:45 < zippe> But I never actually got into it, when it came down to "write a program to generate your build system"
2014-03-16T07:51:14 < zippe> how do I 'clean' the laks_demo build?
2014-03-16T07:51:21 < zyp> scons -c
2014-03-16T07:51:38 < zippe> it leaves the target directories, is that right?
2014-03-16T07:51:38 < zyp> with scons you don't have to make a clean rule, they are implicit
2014-03-16T07:52:08 < zyp> only generated targets gets deleted with -c
2014-03-16T07:52:29 < zyp> I haven't tried generating directories

2014-03-16T07:54:27 < zippe> The variant dirs seem persistent
2014-03-16T07:54:29 < zippe> No big deal
2014-03-16T07:55:03 < zippe> It looks like basically all the python can be replaced with:
2014-03-16T07:55:03 < zippe> arm-none-eabi-g++ -c -std=c++11 -fno-exceptions -fno-rtti -Wno-pmf-conversions -O2 -Wall -ggdb -mcpu=cortex-m4 -mthumb -ffunction-sections -mhard-float -DSTM32F4 -I../laks ../laks/*/*.cpp
2014-03-16T07:55:37 < zyp> that sounds about right
2014-03-16T07:55:44 < ds2> how easy is it to cross compile with scons?
2014-03-16T07:56:03 < ds2> is there a equiv of make CC=/opt/arm/bin/arm-gcc ?
2014-03-16T07:56:03 < zippe> "just add more python"
2014-03-16T07:56:12 < zyp> ds2, yes, exactly that
2014-03-16T07:56:29 < zyp> ds2, http://cgit.jvnv.net/laks/tree/build_rules#n16
2014-03-16T07:56:36 < zippe>         env.Replace(
2014-03-16T07:56:36 < zippe>                 CC = '${TOOLCHAIN}gcc',
2014-03-16T07:56:45 < ds2> ohhhhh
2014-03-16T07:56:53 < zippe> Which is obvious enough on reading, but I'd never have guessed it
2014-03-16T07:56:53 < ds2> never cross compiled wiht scons
2014-03-16T07:57:19 < zippe> so env.SetDefault is ?= then?
2014-03-16T07:57:51 < zyp> SetDefault sets a variable if it isn't already set
2014-03-16T08:00:14 < zyp> the way I'm using scons in laks is a bit untraditional, since I've tailored it for using laks as a submodule in a parent project
2014-03-16T08:00:37 < zyp> http://cgit.jvnv.net/suzumebachi/tree/SConstruct?id=2fc77d2 <- a traditional standalone approach would look something like this
2014-03-16T08:02:38 < zippe> strings for options is annoying; is there a way to build them from lists?
2014-03-16T08:03:13 < zyp> yes, scons takes either
2014-03-16T08:03:35 < zippe> CFLAGS = -O2 -Wall etc?
2014-03-16T08:04:00 < zyp> what do you mean now exactly?
2014-03-16T08:04:10 < zippe> In the example you just gave, why are the flags strings, but CPPDEFINES is a list?
2014-03-16T08:04:24 < zippe> I mean that I frequently have very long lists of flags
2014-03-16T08:04:43 < zippe> So writing a single string without line-wrapping is impossibly tedious
2014-03-16T08:05:00 < zyp> because I'm too lazy to type «', '» between each flag
2014-03-16T08:05:41 < zyp> in the newer files I've wrapped the flags in Split() which splits them into lists on whitespace
2014-03-16T08:06:31 < zippe> unf
2014-03-16T08:07:03 < zyp> Split('-O2 -Wall') is equivalent to ['-O2', '-Wall']
2014-03-16T08:07:20 < zippe> Ok, but why would you do the first?
2014-03-16T08:07:32 < zyp> 07:05:00 < zyp> because I'm too lazy to type «', '» between each flag
2014-03-16T08:08:13 < zippe> hrm
2014-03-16T08:08:26 < zyp> anyway, both lists and strings can be joined with +
2014-03-16T08:08:38 < zippe> right, and += to append I guess
2014-03-16T08:08:43 < zyp> yes
2014-03-16T08:09:22 < zippe> How hard is it to get the build not to poop in the source tree?
2014-03-16T08:09:38 < zyp> not hard at all
2014-03-16T08:10:43 < zyp> although I haven't tried that without using sconscripts
2014-03-16T08:11:35 < jpa-> doesn't really work without sconscripts
2014-03-16T08:13:16 < zyp> there's also a BuildDir command
2014-03-16T08:15:08 < zyp> but yeah, then you need to specify the sources as relative to the builddir
2014-03-16T08:21:53 < zyp> hmm, waf actually looks kinda interesting, I'll have to take a closer look at that later

2014-03-16T08:56:29 < zyp> that's the sane way
2014-03-16T08:56:49 < dongs> like i want thermal on USB to be 45" cross not 90" cross

2014-03-16T08:57:00 < zyp> oh
2014-03-16T08:57:03 < zyp> dunno
2014-03-16T08:57:11 < dongs> in dicktrace its just rightclick pad and override thermals :)

2014-03-16T09:30:42 < zyp> I haven't found that yet, I just saw the «set board shape from selection» option
2014-03-16T09:31:29 < zyp> but when you mention it, it kinda makes sense since AD14 were supposed to have all those new possibilities for weird boards

The amount of leg work that's needed for such a thing would make anyone's head spin; creating technical drawings, sourcing parts, negotiating prices, you name it, we've been checking it off the list.
2014-03-16T10:30:52 < dongs> wow,, such hard work!!!

2014-03-16T15:53:41 < PaulFertser> Rickta59: no secret, just add a quirk for stlinkv1 to /etc/modprobe.d/ somewhere
2014-03-16T15:53:46 < Rickta59> i did that

2014-03-16T15:58:52 < PaulFertser> Rickta59: stlinkv1 sucks, it doesn't support SWO anyway. I think either upgrade to BMP or stlinkv2. With the latter it's easier to use SWO, with the former, you do not need any additional tools (openocd), just plug it in, start gdb and debug :)
2014-03-16T15:59:23 < Rickta59> yeah i have a stellaris board with BMP on it
2014-03-16T15:59:38 < Rickta59> i just wanted to get this working so i could document it

2014-03-16T16:01:01 < Rickta59> and i was wondering why i couldn't connect with openocd .. and then looked and noticed it was constantly resetting in my syslog

2014-03-16T16:47:54 < qyx_> i can smell too much linears
2014-03-16T16:48:43 < madist> linears are a good choice on a DSP board I guess ?
2014-03-16T16:49:18 < madist> or does it not matter due to the digital noise ?
2014-03-16T16:50:15 < qyx_> st even has a rf transceiver with power stage supplied with internal smps
2014-03-16T16:50:48 < qyx_> so probably even rf could work with switched supplies if you try enough
2014-03-16T16:54:04 < bvernoux> oups I was on wrong channel ;)

2014-03-16T19:11:01 < englishman> gotta use this in my next project http://www.maxwell.com/products/microelectronics/docs/hsn1000_rev3.pdf
2014-03-16T19:12:57 < madist> how many meters away from the blast do you have to be for that sensor to operate ?
2014-03-16T19:13:30 < MrMobius> you mean if you are too close to the blast it wont work?
2014-03-16T19:15:38 < madist> > Doses of more than 1,000 rad are almost invariably fatal
2014-03-16T19:15:43 < madist> ^ from wikipedia
2014-03-16T19:15:52 < madist> > The detection threshold of the HSN-1000 is adjustable within the
2014-03-16T19:15:53 < madist> range of 2 x 105 rad(Si)/s to 2 x 107 rad(Si)/s.
2014-03-16T19:15:56 < madist> ^ from your pdf
2014-03-16T19:16:07 < MrMobius> i could have told you that. that is when you die on the game Fallout
2014-03-16T19:16:16 < madist> that's 10^5 and 10^7
2014-03-16T19:17:35 < madist> hmm... have i misread something
2014-03-16T19:18:12 < madist> the max sensitivity of that thing is 200,000 rads ? that's extremely not sensitive.
2014-03-16T19:18:26 < englishman> it's a nuclear event detector, not a wussy detector
2014-03-16T19:19:57 < englishman> hm no i think your units are messed up
2014-03-16T19:20:28 < englishman> what is an Si?
2014-03-16T19:20:36 < englishman> rad(Si)/s
2014-03-16T19:21:58 < madist> Sievert
2014-03-16T19:22:03 < englishman> isnt that Sv
2014-03-16T19:22:11 < madist> hmm
2014-03-16T19:22:25 < englishman> The SI unit for absorbed dose is the gray (Gy), but the “rad” (Radiation Absorbed Dose) is commonly used. 1 rad is equivalent to 0.01 Gy.
2014-03-16T19:22:27 < madist> oh SI rads
2014-03-16T19:22:38 < madist> there are a couple of different definitions of a Rad

2014-03-16T20:35:24 < Steffanx> Sounds familiar :D

2014-03-16T20:35:45 < Steffanx> oh no, that wasn't a kernel panic. Just a unrecoverable hang.
2014-03-16T20:35:45 < GargantuaSauce> what is the course of action we came up with
2014-03-16T20:35:56 < GargantuaSauce> yeah i had some of those too, with a slightly different firmware
2014-03-16T20:36:12 < Steffanx> and this was with some rl232-something of ftdi
2014-03-16T20:36:41 < GargantuaSauce> oh so it's strictly the host-side usb drivers that are immeasurably awful?

2014-03-16T20:43:01 < GargantuaSauce> cause that will totally be less likely to have kernel bugs right RIGHT??? fuck
2014-03-16T20:43:25 < Steffanx> libopencm3 and/or chibios has no better code?
2014-03-16T20:43:29 < Steffanx> or is gpl not an option?
2014-03-16T20:43:57 < GargantuaSauce> i don't particularly like chibios, should probably give libopencm3 a shot next i guess

2014-03-17T00:16:48 < tp> cool, like a Segway
2014-03-17T00:16:56 < upgrdman> here's an old vid, before i etched my custom pcb, or used wheel encoders:

2014-03-17T00:17:57 < tp> and it looks like your vinyl wheel encoders are quadrature output ?
2014-03-17T00:19:45 < upgrdman> ya
2014-03-17T00:23:09 < tp> nice, love the face plant!
2014-03-17T00:23:24 < tp> the robot has fast reactions
2014-03-17T00:25:38 < upgrdman> most of that was me. without the wheel enocders, the robot has a tendency to drift faster and faster...
2014-03-17T00:25:58 < upgrdman> it balances on it own without the encoders, but you better not let it drift off :)

2014-03-17T01:40:15 < mervaka> i wanted 256x, but the clocks only allow 58x roughly :/
2014-03-17T01:40:20 < mervaka> doh
2014-03-17T01:40:40 < mervaka> 256 would have allowed 16b

2014-03-17T01:46:57 < synic> This code should toggle PA_9, right? https://gist.github.com/synic/9591543
2014-03-17T01:48:12 < dongs> you know thre IS a #define for GPIO_Pin_9 type stuff right..
2014-03-17T01:48:22 < synic> no, no I do not
2014-03-17T01:49:13 < synic> I've got an stm32f030 chip set up here on a protoboard, 8Mhz external clock
2014-03-17T01:49:31 < synic> st-link detects it fine, and I can load that program to the chip, but the LED doesn't blink
2014-03-17T01:49:49 < synic> so I'm wondering if I'm referencing it wrong or something
2014-03-17T01:49:55 < GargantuaSauce> what does the led do?
2014-03-17T01:50:01 < synic> the led does nothing
2014-03-17T01:50:58 < GargantuaSauce> have you used the debugger?
2014-03-17T01:51:54 < synic> my setup is eclipse with the gnuarm plugin.  Unfortunately, when I try to compile it in Debug mode, it says the program is too big for the FLASH (I'm using a TSSOP 20 stm32f030)
2014-03-17T01:52:07 < synic> but I do have the program loaded in GDB, I just can't do much with it
2014-03-17T01:52:34 < GargantuaSauce> get rid of stdio and printf and use the debugger to watch the execution
2014-03-17T01:54:32 < synic> huh, so it was stdio making it too big?
2014-03-17T01:54:38 < dongs> you could also try keil
2014-03-17T01:54:42 < dongs> how much flash on that 030?
2014-03-17T01:54:48 < dongs> <= 32k you can use free demo forever.
2014-03-17T01:54:51 < GargantuaSauce> check to see if systick_config actually writes to the CTRL register and enables the interrupt
2014-03-17T01:54:56 < dongs> and debugger there absolutely rapes eclipse/gnu crap

2014-03-17T01:59:09 < zyp> or perhaps just the debugger setup is broken
2014-03-17T01:59:10 < synic> tbh, I don't know if I've got it set up on this protoboard correctly, it's my first attempt
2014-03-17T01:59:47 < synic> but st-link does give the correct information about it
2014-03-17T02:00:32 < synic> I've got my nucleo board hooked up to it via SWD, and I'm using the stlink on that

2014-03-17T02:09:30 < aadamson> dongs,  I have the 152 nucleo and no it doesn't at least not obvious have a switch for the usb
2014-03-17T02:09:36 <+dekar_> oh, then maybe I should give them a second look. ST gave me quite a bunch at embedded world.
2014-03-17T02:09:37 < aadamson> its on the 103 part only
2014-03-17T02:09:56 < aadamson> mayber there is some magic that I don't know I'm not sure, is does present a vcp
2014-03-17T02:10:05 < aadamson> I wonder if the vcp is to the uart on the target
2014-03-17T02:10:33 <+dekar_> yeah I also thought it was only VCP in order to be more like arduino :/
2014-03-17T02:10:50 < aadamson> maybe that's what it is... I'll have to look at that
2014-03-17T02:11:01 < aadamson> didn't think about that until just now, but that makes perfect sense
2014-03-17T02:11:09 < englishman> it says the VCP is on the stlink v2.1, and you can connect it to target usart
2014-03-17T02:11:30 < synic> ok, I have news.  As I was rebooting, the LED started blinking
2014-03-17T02:11:43 < synic> if i unplug the nucleo board, it stops blinking
2014-03-17T02:11:56 < synic> not sure what's going on there
2014-03-17T02:12:09 < synic> (the protoboard has it's own external power)
2014-03-17T02:12:23 < dongs> oh that weird dfn is avreg
2014-03-17T02:12:28 < dongs> i thought it was some kinda usb switch

2014-03-17T02:12:38 < dongs> ya no native usb
2014-03-17T02:13:25 < dongs> need to buy the saparkfun usb breakout
2014-03-17T02:14:00 <+dekar_> dongs, maybe you could use some arduino bitbang usb instead :P
2014-03-17T02:14:50 <+dekar_> now that the STM32 is arduino compatible, one has to solve problems the arduino way
2014-03-17T02:15:34 < englishman> i heard you can break off the stlink and attach it to an arduino uno and get debugging
2014-03-17T02:16:14 < synic> why on earth would it need the stlink attached to run the program?  Perhaps I needed to do something with the boot pin
2014-03-17T02:17:44 < dongs> no
2014-03-17T02:18:24 < synic> while I'm downloading keil, I've been connecting and disconnecting with the stlink utility
2014-03-17T02:18:35 < synic> when I connect, the program stops, when i disconnect, the program runs
2014-03-17T02:21:11 <+dekar_> well the original arduino uses the DTR pin of the FTDI to reset, maybe the nucleo does the same?

2014-03-17T02:39:52 < Laurenceb> back from Londonistan
2014-03-17T02:40:06 < Laurenceb> epically trolled some towelheads on the tube
2014-03-17T02:40:18 < Laurenceb> with my pre-prepared bacon sandwich
2014-03-17T02:40:28 < dongs> Laurenceb is actually from basingstoke
2014-03-17T02:40:57 < Laurenceb> troll level is not yet at Tom66 mark
2014-03-17T02:42:41 < dongs> one of the tests tom66 did to his boards was getting them in differnet colors and throwign them into the grass
2014-03-17T02:42:45 < dongs> to see which one is more contrast

2014-03-17T02:43:30 < dongs> the epic troll part was getting people to pay him $1500

2014-03-17T02:48:07 < zyp> problem is that it was pre-prepared, you should have brought with you a portable cooker instead
2014-03-17T02:49:45 < dongs> presure cooker in backpack
2014-03-17T02:51:15 < emeb> zyp: first Zybo test + linux user app achieved.

2014-03-17T02:52:22 < emeb> the tool flow required is... involved.

2014-03-17T02:56:00 < zyp> judging by what I've seen from the microblaze toolchain, the problem is rather proprietary xilinx bullshit
2014-03-17T02:56:16 < emeb> three closed-source vendor GUI tools from Xilinx (planAhead / XPS / ISE), a bunch of board-specific definition files and a few hours of button poking and you've got a bitstream + some software spec files.
2014-03-17T02:56:37 < emeb> then it's into Eclipse + arm gcc to build the linux app
2014-03-17T02:57:07 < zyp> eww
2014-03-17T02:57:23 < emeb> and that's just the quick & dirty approach that doesn't involve building a kernel and writing custom drivers.
2014-03-17T02:57:34 < zyp> isn't planahead just the constraints tool?
2014-03-17T02:58:16 < emeb> planahead is used to set up the project and drive the other tools
2014-03-17T02:59:04 < zyp> say, how is altera on smaller fpgas, if one wanted to avoid xilinx tools completely? :p

2014-03-17T02:59:28 < zyp> are they comparable on price to xilinx?
2014-03-17T02:59:31 < emeb> I've used Quartus on simple Altera FPGAs. It's very much like ISE.
2014-03-17T03:00:00 < emeb> in general the Altera FPGAs are a tiny bit more $$ than equivalent Xilinx parts.

2014-03-17T03:00:36 < zyp> hmm, ok
2014-03-17T03:01:11 < Bird|ghosted> dongs: ISE is a mess.
2014-03-17T03:01:24 < dongs> well aware

2014-03-17T03:04:39 < emeb> it's possible to build Xilinx bitstreams w/o using ISE, but then you get into a bunch of opaque command line tools. I've done it with makefiles and it works, but it's ugly.
2014-03-17T03:04:58 < zyp> I also did that years ago
2014-03-17T03:05:17 < zyp> at the time I still used makefiles

2014-03-17T03:06:17 < zyp> but makefiles (and other build systems) are rather useless for the task, since most input files gets combined in the first step, and everything after is mostly one input one output commands
2014-03-17T03:06:35 < zyp> so pretty much every change ends up rerunning everything anyway
2014-03-17T03:06:42 < zyp> so you might as well just do a plain script
2014-03-17T03:06:49 < emeb> yes - it has the advantage that you're not running both ISE and the actual synthesis tools simultaneously.
2014-03-17T03:07:10 < emeb> which makes a difference if you don't have butt-loads of RAM - ISE is a pig.
2014-03-17T03:07:25 < zyp> RAM is cheap :)
2014-03-17T03:07:28 < emeb> not much of an issue these days of course
2014-03-17T03:07:37 < emeb> but 10yrs ago 4GB was a big deal
2014-03-17T03:07:42 < zyp> true
2014-03-17T03:08:06 < emeb> so these days I usually just use ISE :P
2014-03-17T03:08:21 < emeb> (or Quartus as the case may be)

2014-03-17T13:39:58 < Cyric> hey...i discovered something (in my opinion) very strange on the USART interface in the L-series
2014-03-17T13:40:46 < Cyric> basically i initializate the usart with 9600 baud rate
2014-03-17T13:41:35 < Cyric> and by using the MSI i get a BIT period of 0,1ms
2014-03-17T13:41:58 < Cyric> and by using the HSI i get a BIT period of 14uS
2014-03-17T13:43:07 < Cyric> so basically the choice of the clock change the baud rate....
2014-03-17T13:44:01 < Cyric> i did the same test on the F100 discovery and this NOT happens... i get a BIT period of 0,1mS indipendently from the clock source used
2014-03-17T13:44:24 < Cyric> is this normal?
2014-03-17T13:45:00 < Cyric> isn't the baud rate controlling the BIT period?
2014-03-17T13:45:53 < Bird|ghosted> Cyric: check the UART prescaler
2014-03-17T13:46:41 < Cyric> so do i have to slow down the clock?
2014-03-17T13:46:58 < Cyric> is the uart only working with a specific clk frequency?
2014-03-17T13:47:37 < Bird|ghosted> Cyric: it sounds like the HSI is feeding a faster clock in than the MSI for a given divider setting
2014-03-17T13:49:14 -!- twixx [~Wenzel@hq.aura-optik.de] has quit [Quit: Leaving.]
2014-03-17T13:49:58 < Cyric> yes... but is this going to change the baud rate? the STM should fix this and adjust the baud rate of 9600 ... right?
2014-03-17T13:50:06 < karlp> how exactly are you initializing the baud rate and the uart?
2014-03-17T13:50:32 < dongs> ^ stdperiphlib will init based on HSE_VALUE
2014-03-17T13:50:35 < dongs> or HSI_VALUe or hwatever
2014-03-17T13:50:44 < dongs> check what UART_Init() or somesuch does
2014-03-17T13:50:51 < karlp> which in turn is what sets the APB1/APB2 speeds
2014-03-17T13:50:52 < dongs> there's gonna be a constant in there, and its most likely build-time shit
2014-03-17T13:51:06 < Cyric>    USART_InitStructure.USART_BaudRate = 9600;
2014-03-17T13:51:18 < dongs> right, look what USART_INit() does with that.
2014-03-17T13:51:20 < karlp> ok, but that init code need sto know what your cpu clock is
2014-03-17T13:51:24 < karlp> it's not magic
2014-03-17T13:51:46 < dongs> look at stm???_usart.c for where it uses USART_InitStructure.USART_BaudRate
2014-03-17T13:52:07 < dongs> i need to do similar shit on F1 soon
2014-03-17T13:52:12 < dongs> usart_init is hardcoded
2014-03-17T13:52:18 < dongs> but i need to add dynamic clock freq
2014-03-17T13:52:23 < dongs> so I'll probly have to rewrite usart_init
2014-03-17T13:52:30 < dongs> to grab the value from RCC or something
2014-03-17T13:52:52 < jpa-> dynamic clock freq is very annoying due to stuff like that.. though if you can keep the APB1/APB2 clocks constant, it is somewhat easier
2014-03-17T13:53:01 < dongs> cant
2014-03-17T13:53:12 < dongs> its 72/80mhz
2014-03-17T13:53:49 < Steffanx> overclocking your f1?
2014-03-17T13:53:49 < jpa-> could get constant 8MHz :P
2014-03-17T13:55:07 < dongs>   /* Configure the USART Baud Rate -------------------------------------------*/
2014-03-17T13:55:07 < dongs>   RCC_GetClocksFreq(&RCC_ClocksStatus);
2014-03-17T13:55:12 < dongs> but that shit uses constants
2014-03-17T13:55:26 < dongs> RCC_Clocks->SYSCLK_Frequency = HSI_VALUE;
2014-03-17T13:55:27 < dongs> fale
2014-03-17T13:55:31 < dongs> hm wait i think i fixed that actually
2014-03-17T13:55:52 < dongs> RCC_Clocks->SYSCLK_Frequency = (hse_value >> 1) * pllmull;
2014-03-17T13:55:53 < dongs> ya
2014-03-17T13:55:57 < dongs> and i set hse_value in _startup
2014-03-17T13:56:19 < dongs> man so much crap in RCC_Getclcoks
2014-03-17T13:56:20 < dongs> jesus
2014-03-17T13:56:23 < dongs> like 50 lines of nonstop shit
2014-03-17T13:56:32 < dongs> everytime i look at stdperiphl code i wanna stab
2014-03-17T13:56:36 < jpa-> you found crap in stdperiph? really?
2014-03-17T13:57:10 < dongs> ya, no wai
2014-03-17T13:58:44 < Cyric> so basically i have to keep costant the ratio between SYSCLK and APB2?
2014-03-17T13:58:58 < dongs> you dont have to KEEP it, you just have to know what it is
2014-03-17T13:59:04 < dongs> and see what stdpierph code does iwht it
2014-03-17T13:59:07 < dongs> i.e how its calculated
2014-03-17T13:59:11 < Cyric> ok
2014-03-17T13:59:26 < dongs> that stuff i pasted was from F1, i have no idea what it does on L1
2014-03-17T13:59:39 < dongs> F1 for exampel cant run at 72mhz off HSI
2014-03-17T13:59:41 < dongs> 64mhz is max
2014-03-17T13:59:56 < Cyric> but F1 works fine
2014-03-17T14:00:11 < dongs> when you run off HSE, HSI, MSI on L1, is sysclk same?
2014-03-17T14:00:12 < Cyric> i can swich several sources with different speeds and the
2014-03-17T14:00:21 < dongs> (i.e. can you confirm it by sending sysclk/2 to MCO and scope that piN?
2014-03-17T14:00:34 < Cyric> no is not the same...
2014-03-17T14:00:41 < dongs> so, thats your problem
2014-03-17T14:00:44 < Cyric> the LED blink faster on HSI
2014-03-17T14:00:45 < dongs> are you dynamically switching?
2014-03-17T14:01:06 < Cyric> for now i am just trying and flashing every time
2014-03-17T14:01:25 < Cyric> but eventually yes... i would like to be able to change my clock source
2014-03-17T14:01:43 < Cyric> depending on the power status of my cpu
2014-03-17T14:02:23 < dongs> then get ready to understand how clocks work
2014-03-17T14:02:31 < dongs> start by reading stdperiph and be prepared to fix stuff thats hardcoded.
2014-03-17T14:02:46 < Cyric> mmm ok
2014-03-17T14:02:46 < dongs> you'll need to spend time in _rcc and _usart .c
2014-03-17T14:03:35 < Cyric> i should copy it from the F1 version...there was working

2014-03-17T14:19:24 < Fleck> why?
2014-03-17T14:19:24 < Steffanx> because ..
2014-03-17T14:19:38 < Cyric> mainly for two reasons:    1- there is no PIN NAME on the board and the pin does not follow a logic order
2014-03-17T14:19:48 < Fleck> ouch
2014-03-17T14:20:03 < Cyric> so pin A3 is pin 22 and pin A2 is pin 32 or whatever...

2014-03-17T16:36:16 < vadmeste> Thanks.. It seems that my while (1) { USBH_Process(&USB_OTG_Core, &USB_Host) ; __WFI() ; } will block my USBH state machine.. Does someone think that's a normal thing ?

2014-03-17T16:43:31 < karlp> blah[0] = int16 & 0xff >> 8; blah[1] = int16 & 0xff would be big endian wouldn't it?
2014-03-17T16:46:44 < ASenR> hello, everyone, I want to use Jlink to debug my program in linux, and I have downloaded the suite from segger.com. I also run JLinkGDBServer in linux, and it shows "Waiting for GDB connection...", then I run arm-none-eabi-gdb, but it seems doing nothing...

2014-03-17T16:47:39 < karlp> if you aren't getting usb interrupts, then usb probably isn't doing anything...

2014-03-17T17:42:06 < tp> synic:  yes, I used swd to reprogram a STM32 in a V1 discovery board
2014-03-17T17:42:11 < Lux> if I want to power a stm32 from a 1s lipo, a 2.5V ldo vreg is probably the way to go right ?

2014-03-17T17:49:29 < ASenR> tp, your tutorial is good, I have collected it
2014-03-17T17:50:52 < tp> make sure you refer to the latest openocd info, as it's much more recent than my old tute
2014-03-17T17:51:16 < tp> Lux:  3.7 to 4.2v at the lipo depending on charged or charging ?
2014-03-17T17:56:17 < Lux> no the range is from 3.0V to 4.2V
2014-03-17T17:56:44 < Lux> where as 4.2V is charged and 3 is empty
2014-03-17T17:56:58 < tp> and 3.7 is fully charged ?
2014-03-17T17:57:07 < tp> 4.2 is charging ?
2014-03-17T17:57:12 < Lux> :/
2014-03-17T17:57:40 < tp> I guess that 4.2 is too much for a 3.3 v arm ?
2014-03-17T17:57:44 < Lux> 4.2V is fully charged obviously
2014-03-17T17:57:57 < jpa-> use a regulator
2014-03-17T17:58:03 < tp> so you'll need a regulator of some kind
2014-03-17T17:59:08 < ASenR> tp, I hope you can tell me how can I make the gdb like your in your tutorial (25)
2014-03-17T17:59:08 < tp> if long battery life is important, perhaps a BUK is more suitable than a LDO ?
2014-03-17T17:59:46 < jpa-> at those voltage differences, linear is probably best
2014-03-17T17:59:53 < Lux> jpa-: yeah, I'll do that, do you have any idea if I can use a 3.3V ldo if the input voltage can drop below 3.3V ?
2014-03-17T18:00:09 < jpa-> Lux: yes, but it will not be regulated anymore
2014-03-17T18:00:13 < tp> ASenR:  gdb comes with the arm-none-xxx you get from the repo
2014-03-17T18:00:24 < Cyric> I agree... also because the current is very low
2014-03-17T18:00:33 < jpa-> Lux: li-ion will be mostly empty at 3.4 V anyway
2014-03-17T18:00:40 < Lux> as long as it still supplies some current I'm fine with it

2014-03-17T18:01:10 < jpa-> Lux: note also that if you discharge a li-ion battery below about 2.7V, it will be damaged
2014-03-17T18:01:29 < Lux> yeah, I know
2014-03-17T18:01:31 < tp> Cyric:  good point, low current is well suited for a series regulator
2014-03-17T18:01:51 < Lux> I was planning to sense the lipo voltage and put the mcu in a power down mode to save it
2014-03-17T18:02:02 < tp> unless of course that same reg is supplying servo motors ?
2014-03-17T18:02:03 < Cyric> i am planning to do the same
2014-03-17T18:02:08 < ASenR> tp, no, I didn't mean it, I am just talking about the two window above XD
2014-03-17T18:02:33 < tp> ASenR:  ?
2014-03-17T18:02:55 < Cyric> the problem is that you have to use ADC for sensing the voltage...plus you must use a voltage divider (you cannot sense direclty VBATT at 3.7 Volt)
2014-03-17T18:03:22 < tp> and you need to remove the load at 2.7v or damage the battery ?
2014-03-17T18:03:56 < tp> there has to be specialised lipo chips that do all this available ?
2014-03-17T18:04:37 < ASenR> tp, http://imagebin.org/299747 , here, i just want to know how did you get the two windows
2014-03-17T18:05:01 < Lux> Cyric: yeah that's an issue, from what I read the L1 series also has some voltage detection circuit build in, you might be able to use that
2014-03-17T18:05:40 < Cyric> Really??? i was looking for it and i did not found any...
2014-03-17T18:05:53 < Lux> probably getting some low power ldo and making a small test circuit is the best option, there is not really much specified in the datasheets how they behave at lower voltages
2014-03-17T18:05:58 < tp> ASenR:  arm-none-eabi-gdbtui --eval-command="target remote localhost:3333" main.elf
2014-03-17T18:06:33 < Cyric> Lux: where did you read it?
2014-03-17T18:06:43 < Lux> in the datasheet
2014-03-17T18:06:48 < tp> ASenR:  the "arm-none-eabi-gdbtui" provides the text 'gui'

2014-03-17T18:07:15 < Cyric> ok...one day i will read all the 800 pages of the Manual...
2014-03-17T18:07:34 < qyx_> Cyric: in the datasheet, it also has an integrated divider
2014-03-17T18:07:42 < qyx_> which can be connected only when required to save power
2014-03-17T18:07:57 < tp> if the battery has a detection cct attached, wont that draw power and cause the battery to discharge below 2.7v ?
2014-03-17T18:08:02 < tp> eventually ...
2014-03-17T18:08:18 < Cyric> thanks
2014-03-17T18:08:35 < qyx_> the battery can discharge itself even with no circuit attached
2014-03-17T18:08:37 < qyx_> eventually
2014-03-17T18:10:09 < tp> sure, but a detection cct will hasten the discharge unless lipos tend to self discharge quickly ?
2014-03-17T18:10:23 < tp> I'm not familiar with lipos

2014-03-17T18:39:40 < qyx_> vssa in connected internally in that case
2014-03-17T18:40:09 < qyx_> connect vdda to vdd with ferrite bead and bypass with 1uF & 100nF

2014-03-17T20:06:31 < gxti> but i am talking more progressively out of my ass here so i'll just shut up and maybe do some work today
2014-03-17T20:07:41 < Tectu> SlaveToTheSauce, I assume that that one should be on the drive already and I have to manually asign it?
2014-03-17T20:07:50 < SlaveToTheSauce> yeah
2014-03-17T20:08:15 < SlaveToTheSauce> manually or by adding the reference to it associated with your custom usb device id
2014-03-17T20:08:49 < SlaveToTheSauce> i am not familiar enough with wdm stuff to get any more precise than that
2014-03-17T20:09:15 < SlaveToTheSauce> oh PaulFertser i discovered last night that openocd's usb interactions were the (direct) source of my kernel oopses. so the acm driver was leaving usb_core in a bad state or something
2014-03-17T20:09:23 < SlaveToTheSauce> but I updated and the oopses stopped, still breaks though
2014-03-17T20:09:45 < Tectu> who the fuck designed this crap?
2014-03-17T20:10:06 < SlaveToTheSauce> i am pretty sure we all agree that usb is a bit of a clusterfuck in general
2014-03-17T20:10:38 < SlaveToTheSauce> for my stuff i think i am going to start looking at ethernet

2014-03-17T20:19:05 < PaulFertser> SlaveToTheSauce: well... Probably no, as the tainted flag is there for a reason, not just because Linux devs are too religious. It wasn't once people were spending time debugging bugs that were caused by some out-of-the-tree code.
2014-03-17T20:19:22 < PaulFertser> SlaveToTheSauce: but if the bug is an obvious one, probably yes.
2014-03-17T20:19:24 < PaulFertser> So it depends.

2014-03-18T01:41:10 < MrTrick> qyx_: with the given budget and specs, I think the only possible answer is a very long tape measure.
2014-03-18T01:42:41 < qyx_> i bet some india guy will hopefully do it for him
2014-03-18T01:42:41 < MrTrick> I used a very expensive (scanning) laser rangefinder for a project; it had millimetre _precision_, but could be up to 20mm off depending on the surface material. I think you'll find that any non-contact ranging method will be off easily 1-2%, and that's for _expensive_ gear.
2014-03-18T01:43:10 < qyx_> its not for me, someone is asking for it on freelancer.com
2014-03-18T01:44:00 < MrTrick> oh right. :-)
2014-03-18T01:44:27 < Steffanx> perhaps the indian guy that was supposed to deliver this project ;)

2014-03-18T02:11:18 < tp> the rest of the world is designing with GNU/Linux or BSD anyway
2014-03-18T02:11:26 < ds2> until there is a decent MCAD for Linux...
2014-03-18T02:11:58 < tp> it's a interesting story, all high end MCAD was always Unix
2014-03-18T02:12:18 < tp> GE used unix for all their turbine cads etc
2014-03-18T02:12:28 < tp> and probably still do
2014-03-18T02:12:49 < ds2> unix not Linux
2014-03-18T02:13:27 < tp> one of the reasons that Linux lacks a decent PC based MCAD is that they are no sooner released than they get bought out by the very agressive and cashed up windows CAD sellers liek Autocad
2014-03-18T02:13:45 < ds2> bah... Autocad is obsolete
2014-03-18T02:14:03 < tp> if you think that there is a big difference between unix and Linux, then you're sadly ill-informed
2014-03-18T02:14:23 < tp> hahah, not in Au it isnt
2014-03-18T02:14:50 < ds2> there is a very big difference between Unix and Linux
2014-03-18T02:15:05 < ds2> Unix doesn't have that nasty virus called the GPL that premeates Linux
2014-03-18T02:15:06 < tp> one of my daughters is a licensed architect, and she tells me that there are two types of Autocad one sees in professional architech offices in Australia
2014-03-18T02:15:29 < ds2> ah... different market...
2014-03-18T02:15:33 < tp> 1) every pc has autocad, and it's licensed and *ancient*
2014-03-18T02:15:39 < ds2> I am just talking about mechanical stuff
2014-03-18T02:15:51 < tp> 2) every pc has the latest autocad, and it's pirated
2014-03-18T02:15:56 < tp> me too
2014-03-18T02:16:10 < ds2> architech is different from mechanical
2014-03-18T02:16:18 < ds2> most folks use Solid works or ProE for that
2014-03-18T02:16:20 < tp> I happen to like the GPL, it's not a virus to me
2014-03-18T02:17:17 < tp> I don't knwo most folks, only what my daughter tells me re architecture in australia
2014-03-18T02:17:24 < ds2> that little detail keeps out a lot of software offerings
2014-03-18T02:17:57 < tp> I'm sure it does, I recognise and accept there is a large anti GPL movement
2014-03-18T02:18:22 < tp> but I don't worry about it, I like the GPL and abide by it
2014-03-18T02:19:06 < Steffanx> You're too good for this world mr tp
2014-03-18T02:19:12 < tp> the GPL has given me programs I could never have afforded, so I'm sold. I don't have to run some pirate windows app and worry about the BSAA hauling me off to court
2014-03-18T02:19:33 < ds2> some people need working software today.
2014-03-18T02:19:48 < tp> Steffanx:  a issue that will probably be resolved sooner than later as I'm 59 years old :)
2014-03-18T02:20:23 < Steffanx> lol, like GPL is the only way to get free ( as in no-monies) software.
2014-03-18T02:20:24 < tp> ds2:  and what makes you think that commercial software "works" ?
2014-03-18T02:21:19 < Steffanx> oh, you're THAT old. Old'n rusty.
2014-03-18T02:21:31 < tp> I have found 'free' and commercial don't mix. Ive been using a PC since 1981, and other non MSDOS based machines before that, and over that period, commercial software has let me down badly
2014-03-18T02:21:41 < ds2> commercial software 'working' is too broad of a statement
2014-03-18T02:21:58 < tp> Steffanx:  pop over and we can have a arm wrestle, you can discover how 'rusty' I am ;-)
2014-03-18T02:22:33 < Steffanx> mentally..
2014-03-18T02:22:39 < tp> ds2:  you're right, I apologize for my sweeping generalism
2014-03-18T02:23:05 < tp> Steffanx:  I think we are wrestling mentally right now ?
2014-03-18T02:23:25 < Steffanx> Too bad aussie land is on the otherside of the globe :(
2014-03-18T02:23:43 < tp> but I'm not here to antagonise anyone, just add a forceful pro Linux and GPL voice when required
2014-03-18T02:24:04 < Steffanx> ah, that's why mr d. likes you so much.
2014-03-18T02:24:05 < tp> Steffanx:  yep, it sure is, which is a mix of good and bad
2014-03-18T02:24:22 < tp> yeah, dongs can dish it out, doesnt like taking it tho :)
2014-03-18T02:25:31 < tp> but I'm here first to assist where new Linux users and ARM need a hand, as they usually only get a 'use a proper OS' comment from dongs
2014-03-18T02:26:01 < tp> which is silly, as some people don't want to pirate, and cant afford commercial tools etc
2014-03-18T02:26:20 < ds2> i use Linux when possible but for MCAD, that just isn't an option.
2014-03-18T02:26:26 < tp> and of course, some love the reliability and availability of Linux and Gcc
2014-03-18T02:26:36 < tp> ds2:  I understand completely
2014-03-18T02:26:45 < Steffanx> I think most here are used it nowadays :D

2014-03-18T02:28:52 < qyx_> heh architects, similar situation here
2014-03-18T02:29:09 < tp> re autocad and licensing ?
2014-03-18T02:29:30 < qyx_> although my sister is using draftsight for most things
2014-03-18T02:29:30 < Bird|ghosted> I find the 'use a proper OS' comments to be pretty LOLworthy
2014-03-18T02:29:42 <+dekar> there is no proper OS -.-"
2014-03-18T02:29:44 < gxti> is that so BrainDamage
2014-03-18T02:29:47 < gxti> er, Bird|ghosted
2014-03-18T02:29:47 <+dekar> I'd totally pay for one
2014-03-18T02:29:59 < tp> about every 6 months the BSAA will raid some architects office in australia, and we then read the firm is fined $10,000 AUD for the 4 pcs running unlicensed autocad
2014-03-18T02:30:17 < Steffanx> only 10k?
2014-03-18T02:30:18 < Bird|ghosted> gxti: yes.  especially considering the project I'm going into
2014-03-18T02:30:21 < tp> Bird|ghosted:  agree, all OS's suck
2014-03-18T02:30:34 < BrainDamage> Bird|ghosted: sunos?
2014-03-18T02:30:42 < qyx_> haiku!
2014-03-18T02:30:43 < tp> Steffanx:  it's probably all they can afford
2014-03-18T02:30:59 < Bird|ghosted> BrainDamage: heh
2014-03-18T02:31:43 < tp> my business has run Linux only since it started 10 years ago, and the BSAA can walk in here anytime they like
2014-03-18T02:32:18 < tp> it's less stress not having to worry about licences and seats and cpus and all that crap
2014-03-18T02:32:57 <+dekar> until you get RHEL
2014-03-18T02:33:12 < tp> some large business here have had the BSAA drop in for a friendly 'compliance audit' and been fined because some employee installed a non licensed version for one reason or another
2014-03-18T02:33:38 < tp> well theyre commercial, and commercial means all that stuff
2014-03-18T02:33:42 <+dekar> they even charge you for the add-on repository containing qemu/KVM XD
2014-03-18T02:34:06 < tp> I don't need Linux admin help after 17 years, so I don't need RHEL

2014-03-18T02:34:50 < tp> yeah, RH have been making quite a lot of profit, in fact they are one of the OS companies with positive growth in recent years
2014-03-18T02:35:10 < tp> my first full time Linux was RH 4.1 back in 1997
2014-03-18T02:35:33 < gxti> don't worry, RH is busy ruining everything
2014-03-18T02:35:37 < tp> it was free in those days, and RPM's were nothing like today
2014-03-18T02:35:56 <+dekar> I actually feel like getting a professional linux support, using several of my USB devices at the same time generates random kernel panics :/
2014-03-18T02:36:02 < tp> commercialism tends to do that in many cases I have observed
2014-03-18T02:36:16 <+dekar> probably some reentrancy bug in the hidraw kernel module
2014-03-18T02:36:29 < tp> dekar:  what distro ?
2014-03-18T02:36:32 < Steffanx> the kernel dev mailing list isn't professional enough dekar ?
2014-03-18T02:36:43 <+dekar> doesn't matter, even vanilla kernels
2014-03-18T02:37:23 <+dekar> I guess nobody has actually used hidraw with several devices before
2014-03-18T02:37:33 < tp> in my case, I havent had any USB hassles for years, and lets not forget that Bill Gates BIG demo of XP was ruined when he plugged in a USB device and locked the OS solid
2014-03-18T02:37:58 < Steffanx> No, don't point to windows failures tp
2014-03-18T02:38:03 < tp> in front of millions of viewers
2014-03-18T02:38:14 <+dekar> but hey, my OSX kernel panics when I disable the STM32's USB without releasing the pull-up
2014-03-18T02:38:15 < tp> why not ? USB has been a PITA
2014-03-18T02:39:03 < Steffanx> Hmm, don't remember i had/have issues with that dekar
2014-03-18T02:39:33 < tp> I thing by and large USB hassles have been solved, but the field is a moving target, so the pain will probably never stop at the bleeding edge, *regardless* of OS
2014-03-18T02:40:23 < tp> how long since anyone has a serial connect/disconnect issue cause a kernel panic ? ;-)
2014-03-18T02:40:28 <+dekar> Steffanx, well it's a combined bug with their API, if it tells you the device has been unplugged and you free the handle even though the pull-up is still active. It also only happens on my retina macbook :/
2014-03-18T02:40:38 < tp> or a ethernet connect/disconnect
2014-03-18T02:40:48 < gxti> tp: lots apparently
2014-03-18T02:40:57 <+dekar> doesn't happen on the old core2 macbook
2014-03-18T02:41:02 < gxti> my centos 6 fileserver crashes if i use it with some usb serial dongles
2014-03-18T02:41:10 < gxti> either that or it just perma-locks the process that opened it
2014-03-18T02:41:13 < Steffanx> usb, not the good old serial ;)
2014-03-18T02:41:14 < Bird|ghosted> gxti: what chipset do those dongles used?
2014-03-18T02:41:28 < tp> gxti:  thats the USB part, Im was referring to *serial* not usb
2014-03-18T02:42:01 <+dekar> why can't they just write working microkernels? -.-"
2014-03-18T02:42:01 < Bird|ghosted> the PL230x has been cloned many a time, and I'm sure there are bad/crappy clones out there that can mess up the Linux drivers for 'em (are they CDC? HID? vendor? I really have no clue >.>)
2014-03-18T02:42:08 < gxti> then the question is invalid, nobody hotplugs non-USB serial ports
2014-03-18T02:42:24 < tp> gxti:  I guess the filestystem using USB is what was locked as it wasnt unmounted first before USB removal ?
2014-03-18T02:42:51 < tp> Bird|ghosted:  very good point indeed!
2014-03-18T02:42:56 < gxti> Bird|ghosted: actually ftdi and mcp2200 stuff i made myself.
2014-03-18T02:43:05 < gxti> the pl2303 ones never give me any trouble
2014-03-18T02:43:09 < Bird|ghosted> odd
2014-03-18T02:43:10 < Steffanx> and you never dared to file a bug report gxti ?
2014-03-18T02:43:26 < Bird|ghosted> not sure about the mcp2200, but the FTDIs should be reliable
2014-03-18T02:43:27 < tp> there are so many 'clones' and 'copies' that aren't the real deal, it can cause all kinds of hassles
2014-03-18T02:43:34 < gxti> anyway enough dickwaving, back to design
2014-03-18T02:43:40 < Bird|ghosted> I stay *far* away from the PL230x
2014-03-18T02:43:44 < Steffanx> and still your OS shouldn't crash on a bad behaving USB device.
2014-03-18T02:44:25 < Steffanx> Sure gxti.
2014-03-18T02:44:55 < tp> for instance, I bought a CMS50E pulse/oxymeter that had been tested many times on Linux and works fine on USB .... mine doesnt
2014-03-18T02:45:37 < tp> Steffanx:  agreed, crashing is bad form
2014-03-18T02:46:26 < tp> I must say, I'm impressed with the number of capable, knowledgeable designers on this ch, even the windows using ones and dongs

2014-03-18T07:43:35 < ASenR> hello, everyone! I use arm-none-eabi-gcc to generate the elf file, and then use "arm-none-eabi-objcopy -O binary target.elf target.bin" to generate the bin file and then download the bin file into the chip. is there any thing wrong with this procedure?
2014-03-18T07:52:31 < tp> #>  arm-none-eabi-gcc -I. -c -fno-common -O0 -g -mcpu=cortex-m4 -mthumb main.c            --> This will generate "main.o"

2014-03-18T07:53:18 < tp> ASenR:  did you use a .ld file in your process ?
2014-03-18T07:53:58 < PaulFertser> ASenR: why do not you use elf for flashing? What tool doesn't support it?

2014-03-18T07:59:02 < ASenR> PaulFertser, I use JlinkGDBServer, there is only a "loadbin"

2014-03-18T08:01:39 < PaulFertser> ASenR: you can use "load" in gdb itself.
2014-03-18T08:01:50 < PaulFertser> ASenR: also I think OpenOCD supports JLink of all versions.
2014-03-18T08:02:04 < PaulFertser> At least current OpenOCD does.
2014-03-18T08:03:28 < PaulFertser> ASenR: with OpenOCD if you have SRST connected you can do "monitor reset_config srst_only srst_nogate connect_assert_srst" and then "monitor reset halt" from gdb, you'll halt on the very first instruction then and will be able to step through startup code.
2014-03-18T08:05:26 < ASenR> PaulFertser, yes I use load in gdb, but it seems not good as before...
2014-03-18T08:09:38 < PaulFertser> ASenR: check you ld and startup match target controller, try using a known-good procedure (e.g. some mini-project from libopencm3-examples), try debugging on assembly instructions level.

2014-03-18T11:01:45 < Cyric> because i gave a look at the Power Voltage Levels PVD_IN... but they are on the same pin of I2C1... so i cannot sacrificate one I2C port for reading the battery level... so i will implement the same thing by reading the battery voltage with an ADC...

2014-03-18T13:33:38 < edmont> Claude, jpa-, qyx_: i found the problem with the jtag programming
2014-03-18T13:33:46 < edmont> it's the olimex adapter
2014-03-18T13:34:40 < edmont> if i wire the ulink2 directly to my board, it works ok (not at 10 MHz, but with 5 MHz i can program the STM32)
2014-03-18T13:35:00 < edmont> but i dont know how to solve it
2014-03-18T13:35:01 < edmont> https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/
2014-03-18T13:35:08 < edmont> this is the adapter, 20 to 10 pin
2014-03-18T13:35:10 < edmont> ARM
2014-03-18T13:36:05 < edmont> what i notice is that using the adapter makes the NRST to drop to 0.44 V
2014-03-18T13:36:19 < edmont> without the adapter NRST=3V3
2014-03-18T13:36:22 < tp> edmont:  I have a coupe of those adaptors, but havent used them yet
2014-03-18T13:38:25 < edmont> this is the schematic, i don't know what can i do with those 3 resistors: https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/resources/ARM-JTAG-20-10-schematic.pdf

2014-03-18T13:40:24 < Steffanx> i use one of those adapters, but only for SWD using my black magic probe
2014-03-18T13:47:32 -!- alan5 [~quassel@46.165.251.66] has joined ##stm32
2014-03-18T13:47:45 < tp> edmont:  you mean RSt on pin 10 of the 10 pin connector ?
2014-03-18T13:48:55 < tp> Steffanx:  which connector connects to your  black magic probe, the 10 or 20 pin connector of the ARM-JTAG-20-10 ?
2014-03-18T13:49:48 < Steffanx> i have an "old"  one, it only has the 20 pin connector.
2014-03-18T13:49:58 < Steffanx> he is using them the other way around?
2014-03-18T13:50:19 < Steffanx> to be clear: my bmp only has the 20pin connector.
2014-03-18T13:50:50 < tp> Steffanx:  aha, understand
2014-03-18T13:51:16 < tp> the ARM-JTAG-20-10 is just a converter, 20 to 10 pin as I understand it ?
2014-03-18T13:53:20 < edmont> tp: yes
2014-03-18T13:54:15 < edmont> but smth makes the reset pin drop from 3v3 to 0v44
2014-03-18T13:54:31 < tp> edmont:  then the RST connection seems to onlt run between the 10 and 20 pin connectors, it doesnt interact with anything alse on that board
2014-03-18T13:55:01 < edmont> it should be like that
2014-03-18T13:55:25 < tp> must be your board pulling it low ?
2014-03-18T13:56:02 < edmont> nope, my board routes it directly to the pin
2014-03-18T13:57:17 < tp> I mean the programmer board ?
2014-03-18T14:02:28 < PaulFertser> edmont: what software are you using with your olimex and how?

2014-03-18T15:36:39 < edmont> i found the solution: the olimex adapter is not intended to be conected directly to the ulink2
2014-03-18T15:36:48 < edmont> the rows are swapped
2014-03-18T15:40:47 < madist> edmont: what does that mean ?
2014-03-18T15:46:42 < Steffanx> edmont, why you use this adapter btw? Doesn't the ulink2 already have the tiny 10pins header?
2014-03-18T15:47:09 < edmont> madist: it means this: http://i.imgur.com/Gv929jv.jpg
2014-03-18T15:47:19 < edmont> Steffanx: nop
2014-03-18T15:47:25 < Steffanx> oh, got a clone?
2014-03-18T15:47:45 < edmont> no, it's from keil
2014-03-18T15:50:09 < Steffanx> It's not pretty, but can't you remove the case and plug the adapter in there?
2014-03-18T15:50:10 < edmont> but it has more than 5 years
2014-03-18T15:50:21 < Steffanx> the images i see on the web have this tiny connector..

2014-03-18T15:51:29 < Steffanx> and, i think those are clones, show pin 1 (on the pcb) on the top-left side, like the olimex adapter.
2014-03-18T15:51:36 < edmont> i never opened it :)
2014-03-18T15:52:54 < edmont> anyway, i din't have the cable, so it's good i have the one from olimex

2014-03-18T15:57:44 < edmont> 2nd option :)
2014-03-18T15:59:34 < Steffanx> dongs why you didn't help our friend edmont with his problem? You are the proprietary tools guy.

2014-03-18T16:08:35 < dongs> edmont: keil 20pin jtag output is standard shit
2014-03-18T16:08:48 < dongs> that olimex shit is probably fucked.
2014-03-18T16:08:54 < edmont> :)
2014-03-18T16:08:58 < edmont> it seems so
2014-03-18T16:09:07 < dongs> BUT
2014-03-18T16:09:12 < dongs> im looking at my ulink
2014-03-18T16:09:16 < dongs> and the red line is on the left
2014-03-18T16:09:28 < dongs> err
2014-03-18T16:09:29 < dongs> on the right
2014-03-18T16:09:31 < dongs> and on yours its on the le ft
2014-03-18T16:09:39 < dongs> did y ou know you can pop the case open
2014-03-18T16:09:44 < dongs> and thre's a couple differnet plugs in there
2014-03-18T16:09:59 < dongs> and your shit is probably plugged in backwards there

2014-03-18T16:11:08 < dongs> you probly want the arm 20pin thing, and make sure its pin1 is correct way.
2014-03-18T16:12:04 < edmont> 20 pin cable was connected ok
2014-03-18T16:12:27 < dongs> well in taht case the olimex shit is fucked, back to the drawing board
2014-03-18T16:12:40 < dongs> i just made my own adapter thingy so I didnt have to deal with broken stuff.
2014-03-18T16:12:54 < dongs> https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/ is it this you have?
2014-03-18T16:13:27 < dongs> note the 1.27 mm cable needs to be pluged backwards

2014-03-18T16:21:41 < Steffanx> btw edmont, it's the not adapter being faulty, you just try to connect it in a way that is never going to work :P

2014-03-18T16:57:58 < Steffanx> ebay edition of course.
2014-03-18T16:58:12 < englishman> cool, i thought segger was bricking those tho
2014-03-18T16:58:23 < dongs> i got ulink
2014-03-18T16:58:26 < dongs> and jlink-edu
2014-03-18T16:58:40 < dongs> and zyp sent me a legit ulink2-me
2014-03-18T16:58:50 < englishman> any difference between then?
2014-03-18T16:58:51 < dongs> ulink2-me = awesome
2014-03-18T16:59:04 < dongs> yeah differnet tools for differnet shit
2014-03-18T16:59:14 < dongs> jlink can dump full flash easily
2014-03-18T16:59:14 < Steffanx> oh, nice tiny debugger.
2014-03-18T16:59:18 < englishman> how so? they all are used for swd?
2014-03-18T16:59:30 < englishman> stdink cant?
2014-03-18T16:59:55 < dongs> so for some stuff that i make that uses bootloader i will flash botloader over swd, load main app, then dump flash and reflash the rest with that.
2014-03-18T17:00:13 < dongs> i duno im sure it does, but i dont have any stdink with standard 20/10pin jtag cables and i dont wanna dick with -discovery boards
2014-03-18T17:00:18 < dongs> stlink is also pretty slow in debugging
2014-03-18T17:00:33 < dongs> at least in keil, i'd say its ulink > jlink > stdlink
2014-03-18T17:00:34 < dongs> speed-wise
2014-03-18T17:00:38 < englishman> hm cool
2014-03-18T17:00:52 < englishman> and that jlink edu which it says on their site isnt as fast as the more $$ ones?
2014-03-18T17:01:03 < dongs> its good enough for stm32
2014-03-18T17:02:03 < englishman> i wonder if OSCAR delivery will be delayed by lack of 32u4 chips on the market

2014-03-18T17:03:16 < englishman> yeah looks like they will be funded
2014-03-18T17:03:27 < dongs> thats ok, they have plenty of time to fail
2014-03-18T17:03:35 < dongs> just look at matchboxarm
2014-03-18T17:03:53 < englishman> there have been updates on matchboxarm.com im impressed

2014-03-18T17:13:07 < dongs> also newest firmware for ulink-type stuff makes htem usable in cmsis-dap mode
2014-03-18T17:13:16 < nine-tails> i use microsoft compatible hardware, and windows 8.1 pro doesnt support my microsoft compatible hardware
2014-03-18T17:13:16 < dongs> so you can use it outside of keil with stuff that supports that.

2014-03-18T17:18:04 < dongs> DisplayPort 1.2 added support for Multi-Stream Transport (MST), enabling multiple monitors to be used via a single DisplayPort connector. This function requires either monitors that are capable of DisplayPort 1.2 daisy-chaining, or use of a DisplayPort MST Hub. The first MST hub became available in September 2013, enabling up to 3 displays to be connected to a single DisplayPort connector.
2014-03-18T17:18:10 < dongs> september 2013????????????
2014-03-18T17:18:18 < dongs> MST has been avilable for years, surely before 2013

2014-03-19T00:38:06 < ds2> as in the clock is reasonably accurate
2014-03-19T00:38:24 < ds2> i think someone here mentioned the STM32L1's have the fixed internal RC
2014-03-19T00:38:34 < karlp> wat?
2014-03-19T00:38:38 < zyp> fixed?
2014-03-19T00:38:39 < karlp> fixed? what was brokne+'
2014-03-19T00:38:52 < ds2> as in the stm32F1's internal RC osc drifted a lot
2014-03-19T00:39:01 < zyp> are you sure you aren't thinking of the new F0x2 chips?
2014-03-19T00:39:13 < ds2> oh it is the F0x2's?
2014-03-19T00:39:19 < ds2> I am not doing USB
2014-03-19T00:39:25 < ds2> back to the selector interface
2014-03-19T00:39:33 < zyp> the new F0x2 chips has a new HSI48 oscillator which is accurate enough for usb
2014-03-19T00:39:56 < zyp> and does that by calibrating the oscillator from other sources like the USB SOF rate
2014-03-19T00:40:09 < ds2> Oh... no, not that one
2014-03-19T00:40:43 < ds2> I been told the old F1's, etc have horrible internal RC clocks but there are new series that fixes that

2014-03-19T07:18:38 < zyp> who would have guessed
2014-03-19T07:19:13 < ds2> had to rip out a 46pin, 0.1 pitched header cuz of that
2014-03-19T07:19:30 < ds2> solder paste flowed through and left enough of a residue that it was massively shorting things out :(
2014-03-19T07:20:02 < ds2> about the only good thing was having a milli-ohm meter to locate the short to that
2014-03-19T07:20:05 < emeb_mac> ugh
2014-03-19T07:20:25 < ds2> was hoping the paste would stay sticky
2014-03-19T07:20:37 < zyp> huh?
2014-03-19T07:20:56 < ds2> but as a correllary, I now understand why CM's hate via in pad or or via in thermopad

2014-03-19T07:21:19 < ds2> I was hoping it would flow as much. regular melted solder likes to ball up. the paste when warmed with hot air flows like water!
2014-03-19T07:21:30 < ds2> would NOT flow I mean
2014-03-19T07:21:41 < GargantuaSauce> moar flux
2014-03-19T07:21:45 < GargantuaSauce> the answer is always more flux
2014-03-19T07:21:58 < emeb_mac> buy it by the gallon
2014-03-19T07:22:01 < tp> yep, flux is the key
2014-03-19T07:22:11 < tp> buy it by the barrel!
2014-03-19T07:22:18 < zyp> you know, solder paste is really just a mix of solder balls and flux paste
2014-03-19T07:22:18 < ds2> i have added flux to regular solder and never got it to flow like water
2014-03-19T07:22:47 < ds2> I know

2014-03-19T07:23:14 < ds2> but apparently it is a different kind of flux. I normally just use rosin based stuff in a bottle if the wire solder isn't enough
2014-03-19T07:23:14 < jpa-> the flux doesn't mix that well with solder if there is no mechanical mixing
2014-03-19T07:23:32 < ds2> Ah. I see

2014-03-19T07:26:04 < ds2> hot air reflow demostrated the power of self alignment
2014-03-19T07:26:20 < ds2> I had 0603 parts out by maybe 0.1 inche and it just sucked it right in
2014-03-19T07:26:21 < emeb_mac> that's pretty amazing when you see it happen
2014-03-19T07:26:32 < jpa-> for me, hot air reflow has demonstrated the power of lifting 0603 parts standing on one end

2014-03-19T07:26:43 < ds2> lifting?
2014-03-19T07:26:47 < jpa-> it's difficult to heat evenly enough, especially if you have no preheat

2014-03-19T07:27:12 < ds2> how wide of a nozzle?
2014-03-19T07:27:20 < jpa-> about 3cm
2014-03-19T07:27:30 < GargantuaSauce> is that a half-soldered pull-up or are you just happy to see me?
2014-03-19T07:27:40 < ds2> I see... so far no problems

2014-03-19T07:28:02 < jpa-> it was a 4-layer board so pretty much would have needed preheating
2014-03-19T07:28:03 < ds2> only issue was when I tried through
2014-03-19T07:28:11  * emeb_mac has a project coming up with 0402s
2014-03-19T07:28:19 < jpa-> emeb_mac: i always use 0402 at home
2014-03-19T07:28:25 < jpa-> at work they only had 0603 :F
2014-03-19T07:28:32 < emeb_mac> jpa-: hats off to you
2014-03-19T07:28:33 < ds2> I try to preheat by moving the nozzle over a wide area of the board
2014-03-19T07:28:36 < jpa-> such ugly huge parts, some even had some graffiti numbers on them
2014-03-19T07:28:54 < emeb_mac> not looking forward to it
2014-03-19T07:29:06 < jpa-> it's easy
2014-03-19T07:29:15 < emeb_mac> oh?
2014-03-19T07:29:21 < emeb_mac> how do you assemble?
2014-03-19T07:29:28 < jpa-> hand soldering
2014-03-19T07:29:34 < jpa-> just make sure that you lay the pcb so that the soldermasks don't touch, otherwise Tectu_ will get wrong thoughts
2014-03-19T07:29:35 < emeb_mac> kewl
2014-03-19T07:29:45 < emeb_mac> wouldn't want that
2014-03-19T07:30:14 < emeb_mac> I need a stencil on this one - lots of csp pkgs
2014-03-19T07:30:21 < emeb_mac> and dfns
2014-03-19T07:30:32 < jpa-> yeah, those are much worse than 0402 :P
2014-03-19T07:30:45 < emeb_mac> thanks - I feel better already :)
2014-03-19T07:30:57 < ds2> emeb_mac: how are you going to assemble that?
2014-03-19T07:31:08 < emeb_mac> ds2: good question
2014-03-19T07:31:18 < tp> carefully ?
2014-03-19T07:31:26 < emeb_mac> stencil + paste + hand place + hotplate?
2014-03-19T07:31:50 < tp> thats as good as one can do without a pnp machine
2014-03-19T07:31:55 < ds2> hotplate better then oven?
2014-03-19T07:32:08 < jpa-> oven > hotplate > hot air
2014-03-19T07:32:11 < jpa-> IMO
2014-03-19T07:32:25 < tp> a ir oven with the proper temp profile is best
2014-03-19T07:32:49 < tp> and small one can be made or purchased these days that is ok
2014-03-19T07:32:53 < zyp> I haven't tried hotplate, but I certainly don't like hot air
2014-03-19T07:32:56 < ds2> dumb question... what exactly is an IR oven?
2014-03-19T07:33:02 < jpa-> i wonder if IR is really the best.. i would think that all the wrong parts absorb IR and the wrong parts reflect it
2014-03-19T07:33:21 < madisk> that's something i've always wondered
2014-03-19T07:33:36 < madisk> black epoxy should get hot really fast, compared to shiny silver leads
2014-03-19T07:33:37 < tp> it has hotplates above and below a mesh, and they emit strong infrared
2014-03-19T07:33:42 < madisk> exactly the opposite of what you'd want
2014-03-19T07:34:16 < tp> all commercial reflow machines use the same IR hotplates
2014-03-19T07:34:23 < emeb_mac> madisk: trouble is you can't tell what will absorb IR by looking at it
2014-03-19T07:34:37 < emeb_mac> because you see in visible spectrum
2014-03-19T07:34:40 < emeb_mac> not IR
2014-03-19T07:34:46 < madisk> emeb_mac: rough rules of thumb: black > reflective. rough > smooth.
2014-03-19T07:34:59 < tp> theyre kind of like a pizza oven, the belt moves slowly along and carries the pcb under different temp plates according to preset profiles
2014-03-19T07:35:29 < tp> theyre dead simple really, apart from the mechanics and the temp controllers
2014-03-19T07:36:18 < tp> if the right amount of solder paste is applied, the boards come out the other end, spick n span, no further work required other than testing
2014-03-19T07:36:44 < tp> if too much solder paste, you have to clean the boards, flus is everywhere
2014-03-19T07:36:59 < tp> too little solder paste and it's toombstone territory
2014-03-19T07:37:26 < tp> ( I used to run a commercial SMT assembly plant, back in the early 90's)
2014-03-19T07:39:27 < emeb_mac> the voice of experience
2014-03-19T07:40:25 < tp> it was great fun I admit
2014-03-19T07:41:08 < tp> we had single lines producing 2000 assemblies every day, and placers that did 17,000 SMT parts a hour
2014-03-19T07:41:08 < ds2> how is that different from a stock regular oven with glowing elements? don't those emit IR too?
2014-03-19T07:41:23 < tp> ds2:  sure, theyre all much the same
2014-03-19T07:41:34 < ds2> so is that an IR oven?
2014-03-19T07:41:43 < zyp> yes
2014-03-19T07:41:43 < tp> it it doesnt look hot, but IS ferking hot, then it's mostly IR
2014-03-19T07:42:10 < tp> they glow a dim cherry red if I recall correctly
2014-03-19T07:42:23 < tp> but really radiate the heat, being IR
2014-03-19T07:42:25 < ds2> that's why you get a thermocam :D
2014-03-19T07:42:29 < tp> sure
2014-03-19T07:42:47 < tp> but it's pretty simple, you just use a established profile

2014-03-19T07:43:20 < jpa-> ds2: the surface material of the heating elements affects the emitted IR amount a lot.. if you have good ceramic elements, the temperature of the element doesn't have to be so much higher than the target temperature -> better temperature regulation
2014-03-19T07:43:45 < tp> no need to get too techo, if you have too much heat, the board de-laminates, too little and toombstones etc
2014-03-19T07:43:55 < ds2> is a good element one that has low emissivity or high emissivity?
2014-03-19T07:44:01 < tp> just right and the board is perfect
2014-03-19T07:44:01 < jpa-> high emissivity
2014-03-19T07:44:08 < tp> high em
2014-03-19T07:44:14 < ds2> Ohhh
2014-03-19T07:44:24 < ds2> so ideally a carbon black emitter ?
2014-03-19T07:44:31 < jpa-> yeah
2014-03-19T07:44:31 < tp> plus the oven needs time to warm up and settle
2014-03-19T07:44:45 < jpa-> ds2: though you want to maximize the surface area also, to an extent
2014-03-19T07:44:54 < tp> yeah, the elements are just flat grey or black plates
2014-03-19T07:45:09 < ds2> jpa-: so connectors would be bad then?
2014-03-19T07:45:29 < tp> no, the temp profile etc is the important thing
2014-03-19T07:45:47 < ds2> connectors tend to have hiddle surface area
2014-03-19T07:45:54 < tp> and of course, proper smt connectors should be made to take the required temp profiles
2014-03-19T07:46:10 < tp> if they melt, then you have crap elcheapo junk
2014-03-19T07:46:34 < tp> electros in plastic labels have no problem
2014-03-19T07:47:17 < zyp> smt parts tends to be rated for reflow, but pth parts doesn't always
2014-03-19T07:47:18 < tp> one tip tho, watch out when using large copper areas or heatsinks attached before reflow, they can suck up the heat and stop the reflow
2014-03-19T07:48:41 < tp> I've delaminated 8 layer boards with big attached heatsinks, trying to get the solder to flow
2014-03-19T07:49:32 < ds2> that sounds like an expensive thing to do
2014-03-19T07:49:34 < tp> but I don't believe there is a easier neater reflow process than a simple reflow oven
2014-03-19T07:49:50 < tp> all prototypes that the designer wanted to build
2014-03-19T07:50:03 < ds2> w/ or w/o a controller?
2014-03-19T07:50:18 < tp> they left with a pretty ugly burnt prototype and a lot of new design knowledge
2014-03-19T07:50:31 < tp> I think you have to have a controller for the temp
2014-03-19T07:50:48 < tp> it can be a simple mechanical one, but electronic is easier
2014-03-19T07:50:57 < ds2> been reading that some folks just put it in, watch it reflow and turn it off
2014-03-19T07:51:09 < tp> I think fbs is designing one or has finished one for home reflow use
2014-03-19T07:51:21 < tp> yep, with practice it is that easy
2014-03-19T07:51:48 < zyp> I'm pretty happy with my cheap chinese oven
2014-03-19T07:51:56 < tp> if you can do it with a hot air tool, IR reflow will seem a lot easier I think
2014-03-19T07:52:40 < tp> yeah, Ive heard theyre ok if they don't electrocute you on first use, due to the assembler being half asleep after a long slave like day
2014-03-19T07:52:43 < zyp> http://bin.jvnv.net/f/lNfIS.JPG <- this shit
2014-03-19T07:53:01 < zyp> tp, yeah, or catch fire like dongs' apparently did
2014-03-19T07:53:12 < ds2> tthe nice thing about hot air reflow is I can assemble boards piecemeal
2014-03-19T07:53:22 < ds2> useful when bringing up a new design
2014-03-19T07:53:30 < tp> perfect, that would make perfect mini pizzas ;-)
2014-03-19T07:53:58 < tp> ds2:  sure, design and prototyping require a versatile kit
2014-03-19T07:54:28 < zyp> the worst thing I have to say about mine is that the fucking firmware has shitty button handling
2014-03-19T07:54:47 < tp> but if you're doing a production run, clean, neat and working product just rolls of the output of the IR oven, to the sweet sound of $$$ in the bank
2014-03-19T07:54:58 < zyp> you press a button and in most cases it'll register either none or multiple presses
2014-03-19T07:55:07 < ds2> for production, I talk to a CM :D
2014-03-19T07:55:14 < zyp> yeah, same
2014-03-19T07:55:31 < ds2> can't afford a CM for proto unless I got a customer willing to pay through the nose :(
2014-03-19T07:55:33 < tp> that's what we did, production
2014-03-19T07:56:10 < zyp> I'm not aspiring to be a manufacturer :)
2014-03-19T07:56:15 < tp> but get a bad batch of components or solder paste or boards etc and pain rolls out the reflow oven ...
2014-03-19T07:56:42 < tp> I only mention production as thats my past experience
2014-03-19T07:56:54 < tp> it's useful re reflow experience
2014-03-19T07:57:40 < ds2> in practice, how long do solder paste last?
2014-03-19T07:57:46 < ds2> years? months?
2014-03-19T07:57:48 < zyp> depends how you store it
2014-03-19T07:57:48 < tp> 3 months usually
2014-03-19T07:58:06 < tp> and thats stored in a temp controlled fridge specially for it
2014-03-19T07:58:47 < zyp> I've used years old paste, mostly stored in a normal fridge, and then a couple of months in room temp
2014-03-19T07:58:49 < tp> solder paste 'goes off', just like groceries and so all tubes etc have a production date
2014-03-19T07:59:18 < tp> maybe it's ok for protos if it out of date, but it's a disaster on the production line
2014-03-19T07:59:38 < zyp> I think we've already established that we're not doing production lines
2014-03-19T07:59:47 < ds2> so for protos... it isn't a big dea if it is old?
2014-03-19T07:59:51 < tp> we had to be so careful, if supplied paste was out of date, we wouldnt accept it
2014-03-19T07:59:58 < zyp> ds2, in my experience, no
2014-03-19T08:00:06 < tp> ds2, I guess you can add flux, remix etc
2014-03-19T08:00:21 < ds2> hard to do for syringes
2014-03-19T08:00:31 < tp> but Id tend to ditch old paste based on my experiences
2014-03-19T08:00:59 < tp> if your local supplier doesnt have date codes on his paste, don't touch it
2014-03-19T08:01:47 < tp> that's the downside of solder paste, you just cant but too much or you'll have to ditch it at expiry
2014-03-19T08:01:54 < tp> but = buy
2014-03-19T08:02:08 < zyp> ds2, I once bought two cans of paste, and has stored them together, but only used once recently
2014-03-19T08:02:26 < tp> it's the same with SMT components also
2014-03-19T08:02:41 < ds2> SMT components can be baked to rejuvenate them
2014-03-19T08:02:45 < zyp> I ditched it because it was drying out and the sealed one was still pretty fresh
2014-03-19T08:03:19 < tp> ceramic caps have a metalised contact, when they are outside of the expiry date, they wont solder due to oxidation
2014-03-19T08:03:34 < tp> ds2:  some yeah
2014-03-19T08:03:48 < ds2> tp: aren't most plated/tinned to prevent that?
2014-03-19T08:04:53 < tp> say you have a board with ceramic caps and some are old, when you go to manually rework them, and apply a soldering iron tip to the cap, the bloody metalisation just goes 'poof" and it's gone, no contact left, just ceramic!
2014-03-19T08:05:21 < madisk> they would have to be really really old for that to happen
2014-03-19T08:05:27 < tp> ds2, I dunno, but I've seen heaps of them chucked out because theyre out of date
2014-03-19T08:05:46 < tp> depends on the part, some have very thin metalisation
2014-03-19T08:06:18 < tp> when you're in production and you get a batch thats outside the use date, you soon find out
2014-03-19T08:06:21 < madisk> i think it was because earlier they didn't have the tech to plate nickel on the cap
2014-03-19T08:06:36 < tp> the bloody batch has heaps of toombstones usually
2014-03-19T08:06:36 < madisk> so they used silver (?) which dissolves in solder
2014-03-19T08:06:54 < madisk> so too much soldering would remove the plating. but now they use a nickel layer and the solder won't pass that.
2014-03-19T08:06:59 < tp> I think they have had the tech for a long time
2014-03-19T08:07:10 < madisk> yes.
2014-03-19T08:07:16 < tp> they wernt silver plated
2014-03-19T08:07:38 < tp> lol, when I was much younger I made a silver tip for my weller iron
2014-03-19T08:07:38 < madisk> yeah I'm not sure which metal it was exactly.
2014-03-19T08:08:05 < tp> turned the tip out of silver rod, and fitted the magnet to the end
2014-03-19T08:08:11 < tp> it looked lovely
2014-03-19T08:08:48 < tp> I turned on the iron, let it heat up, applied solder and was stunned to see half the tip just flow away!
2014-03-19T08:09:02 < tp> <doh!>
2014-03-19T08:09:30 < tp> the metalisation is some grey stuff
2014-03-19T08:09:36 < tp> nice when new ...
2014-03-19T08:16:29 < dongs> wow
2014-03-19T08:16:31 < dongs> lots of blogs
2014-03-19T08:18:01 < dongs> i see ds2 failed something

2014-03-19T08:28:40 < jpa-> thick gold plating on a copper tip might work
2014-03-19T08:29:04 < tp> it was a beautiful tip, complete with the weller magnet for temp control crimped at the back
2014-03-19T08:29:28 < tp> I think they use hard metals in soldering tips for a reason

2014-03-19T08:33:33 < ds2> is U232 hard?
2014-03-19T08:33:37 < ds2> it is heavy
2014-03-19T08:34:01 < tp> I admit, Ive no idea
2014-03-19T08:34:26 < jpa-> i wouldn't think it would be particularly hard.. but no idea really
2014-03-19T08:34:27 < tp> but the solder has to be able to 'tin' the tip also
2014-03-19T08:34:51 < jpa-> though the idea of a nuclear powered soldering iron is tempting..
2014-03-19T08:35:08 < tp> so that rules out a lot of metals, I think I'll leave it to the soldering iron mfrs to figure it out :)

2014-03-19T08:45:19 < tp> if the pins sit proud at the bottom by much, then while the board is sitting on the wire conveyor belt, it could get pushed up ?
2014-03-19T08:45:36 < zyp> the pins aren't long enough to protude all the way through the board

2014-03-19T08:45:56 < tp> oh, ok, then maybe it was the placer
2014-03-19T08:46:27 < zyp> I also have one board here with the MCU rotated 180 degrees
2014-03-19T08:46:39 < tp> maybe the alignment was abit off and it got stuck proud when it was inserted ?
2014-03-19T08:46:49 < tp> ewww
2014-03-19T08:47:16 < zyp> and I'm about to test the other three I have here that failed tests to check what's wrong with them
2014-03-19T08:47:18 < tp> so jpa- may be right
2014-03-19T08:47:32 < tp> how many failed out of how many ?
2014-03-19T08:48:29 < zyp> six out of 215 or so
2014-03-19T08:48:51 < zyp> I fixed one already, it had a cracked resistor
2014-03-19T08:49:05 < zyp> no visible problem, but it came off in two pieces when I unsoldered it
2014-03-19T08:49:51 < tp> thats a pretty high failure rate
2014-03-19T08:50:36 < zyp> I don't think the numbers are large enough to be statistically significant
2014-03-19T08:50:45 < tp> obviously they didnt test them, so it's reasonable
2014-03-19T08:51:10 < tp> the only way to get minimum failures, is to test each board
2014-03-19T08:51:28 < tp> after assembly with a decent test procedure
2014-03-19T08:51:56 < zyp> yes, I do that myself, that's how I determine these are failures
2014-03-19T08:52:08 < tp> understand
2014-03-19T08:53:38 < zyp> at the moment I'm a couple of boards short, so I'm checking whether I can fix them so I can fulfill the last two orders without having them wait for the next batch
2014-03-19T08:54:06 < zyp> hmm, strange
2014-03-19T08:54:17 < zyp> one of the boards passed test just fine now
2014-03-19T08:54:40 < tp> you *could* just solder fill the connectors under that USB connector, but it's a bit dodgy ?
2014-03-19T08:55:05 < tp> and easy to slip and solder the lot, requiring removal and solder sucking
2014-03-19T08:55:05 < zyp> I figure I'll just hotair it and press it down
2014-03-19T08:55:13 < tp> lol, or that !
2014-03-19T08:56:42 < effractur> hi does someone know the tls troughput speed of the stm32f417?
2014-03-19T08:56:49 < zyp> hmm, wonder if I put this board in the wrong pile, I can't see anything wrong with it
2014-03-19T08:57:26 < jpa-> zyp: nastiest kind of bugs :)

2014-03-19T12:29:20 < dongs> it used to be parallel AT25 type crap
2014-03-19T12:30:17 < jpa-> it's still pretty much the best package if you need to have removable chips for some reason
2014-03-19T12:30:26 < jpa-> much harder to break than DIP
2014-03-19T12:31:17 < zyp> I broke a PLCC socket once, tryin to get out the chip sitting in it
2014-03-19T12:31:28 < zyp> like, ten years ago
2014-03-19T12:31:43 < karlp> didn't have the tool?
2014-03-19T12:31:50 < zyp> correct
2014-03-19T12:32:43 < zyp> needing tools could arguably not make it the best package :p
2014-03-19T12:33:31 < zyp> and fragile shit is still used for the CPU
2014-03-19T12:33:47 < zyp> but it's in a ZIF socket so you don't need tools or force to handle it

2014-03-19T12:56:22 < zyp> so it's either a problem with your bmp firmware or your host side

2014-03-19T13:14:45 < dongs> uh no
2014-03-19T13:14:50 < Steffanx> (according to wikipedia)
2014-03-19T13:15:01 < trepidaciousMBR> Perl was 1987, but it is also weird :)
2014-03-19T13:15:36 < PaulFertser> dongs: m4 is not a scripting language, it's a macro processor.
2014-03-19T13:15:39 < trepidaciousMBR> 1991 is pretty old for a vaguely modern scripting language. Looking at wikipedia, there was REXX I get

2014-03-19T13:15:43 < dongs> PaulFertser: details.
2014-03-19T13:15:50 < Steffanx> Yeah, love this "Syntax Error!" perl script.

2014-03-19T13:16:01 < karlp> m4 can burn in hell with the rest of autotools
2014-03-19T13:16:04 < dongs> PaulFertser: i mean, these are minute details taht dont change the fact that python is trash
2014-03-19T13:16:04 < PaulFertser> You've also forgotten Tcl
2014-03-19T13:16:10 < dongs> yes tcl.
2014-03-19T13:16:37 < zyp> dongs, can't you go bash something useless like ruby instead?
2014-03-19T13:16:41 < PaulFertser> At least python's way, way better than php.
2014-03-19T13:16:42 < trepidaciousMBR> smalltalk is pretty ancient
2014-03-19T13:16:52 < dongs> zyp, ruby is so dead its not realyl worth bashing
2014-03-19T13:16:57 < dongs> the last ruby guy died few weeks ago
2014-03-19T13:16:59 < trepidaciousMBR> I'd far rather use ruby than python
2014-03-19T13:17:28 < dongs> http://developers.slashdot.org/story/13/12/24/1826204/is-ruby-dying haha

2014-03-19T13:18:24 < zyp> «… node.js is taking steam away from Ruby …»
2014-03-19T13:18:33 < PaulFertser> karlp: autotools is the most evolved and the easiest way to make one's software cross-platform. If one cares about GNU/Linux only, then probably autotools is too burdensome.
2014-03-19T13:18:34 < trepidaciousMBR> I didn't think ruby was dying - maybe not as incredibly overhyped as during the ruby on rails craze
2014-03-19T13:19:09 < zyp> also, node.js being a thing is actually pretty weird
2014-03-19T13:20:16 < zyp> «yeah, we have this shitty language in the browser that we use because there's no alternatives, so let's take it and stick it everywhere else too
2014-03-19T13:20:50 < karlp> PaulFertser: evolving from amoeba to algae is a big step, but it doesn't make it good
2014-03-19T13:20:55 < trepidaciousMBR> It's because so many people have learned javascript (and maybe just javascript) for browser development, and they want to use what they know on the server
2014-03-19T13:21:16 < karlp> in other news, got the tiva "connected" lauchpad today,
2014-03-19T13:21:17 < trepidaciousMBR> Given that we will apparently never have a decent language in the browser, the server has to change (mountain to Mohammed I guess)
2014-03-19T13:21:21 < PaulFertser> karlp: are you a cmake fan or what? ;)
2014-03-19T13:21:25 < karlp> and they didn't charge me any duties or taxes on arrival, yay
2014-03-19T13:21:47 < karlp> smaller box than the lmf4 launchpad for a bigger board
2014-03-19T13:22:09 < karlp> heh, comes with a spring loaded roll up ethernet cable :)
2014-03-19T13:22:31 < zyp> time to go buy it just for the cable
2014-03-19T13:22:31 < trepidaciousMBR> They need to add a decent multi-language VM alongside javascript
2014-03-19T13:22:39 < dongs> wat cable
2014-03-19T13:22:45 < dongs> microusb cable??
2014-03-19T13:22:48 < trepidaciousMBR> Then you could have transcompilation to javascript for crap browsers, and run on the VM for decent ones
2014-03-19T13:23:03 < zyp> he said ethernet cable
2014-03-19T13:23:08 < zyp> also, I'm joking
2014-03-19T13:23:09 < karlp> no, this is the one with ethernet onbaord, so microusb cable plsu an ethernet cable
2014-03-19T13:23:14 < dongs> oo
2014-03-19T13:23:14 < dongs> ncie
2014-03-19T13:23:32 < zyp> actually, I just realized I have a spring loaded roll up ethernet cable somewhere
2014-03-19T13:23:44 < karlp> heh, all the silk explaining what pins are is on the bottom
2014-03-19T13:23:45 < dongs> i've got a 300meter spool and crimp ends
2014-03-19T13:23:55 < dongs> for pro ethernettting
2014-03-19T13:23:58 < zyp> I think it's still in my travel backpack
2014-03-19T13:24:32 < zyp> I bought it because it seemed a good idea, but I've never used it because it turned out to not be, it's always too short
2014-03-19T13:24:54 < karlp> tag connect footprint on the bottom
2014-03-19T13:25:09 < Steffanx> heh
2014-03-19T13:25:11 < zyp> same as the old lm4f launchpad then
2014-03-19T13:25:23 < zyp> used to program the icdi firmware
2014-03-19T13:25:33 < dongs> i wonder how many people didnt pay for their launchpads with paypal
2014-03-19T13:25:33 < karlp> but this has connectors for DUAL booster packs!!1!

2014-03-19T17:35:56 < PaulFertser> qyx_: stlinkv2 with swd is fairly well tested, so your reproduction path is apparently lacking some important details.

2014-03-19T17:38:48 < PaulFertser> qyx_: -d3 logs from the current version would be the first step to correctly report it.
2014-03-19T17:38:52 < qyx_> in the spakrkfun's thread ntfreak suggests using newer openocd that 0.7.0

2014-03-19T17:47:46 < synic> so, is there a programming manual somewhere that shows the C structs and functions for stm32f030?  The programming manual on st.com only shows the register names, not the various functions (and their differences from the other families)
2014-03-19T17:48:33 < synic> for instance, I see code examples for things like GPIO_AF_TIM3, but my library doesn't have this, instead it uses GPIO_AF_1
2014-03-19T17:49:12 < synic> which I basically found by just grepping the source of the stm32f0 library

2014-03-19T17:52:46 < PaulFertser> synic: I do not think st has any meaningful reference for their shit-libraries if you do not count comments at the beginning of every header file (which are often wrong).
2014-03-19T17:53:23 < synic> lovely
2014-03-19T17:54:41 < synic> welp, grepping the source eventually worked out for me.  I guess I'll just continue down that road
2014-03-19T17:54:42 < qyx_> ok, now even "halt" doesn't work

2014-03-19T21:01:57 <+dekar> I've built the firmware from git earlier today
2014-03-19T21:02:35 < zyp> anything in dmesg?
2014-03-19T21:04:21 < Thorn> is it BMP?
2014-03-19T21:04:28 <+dekar> http://pastebin.com/9TD3Zge9
2014-03-19T21:04:44 <+dekar> yeah it's a BMP
2014-03-19T21:05:14 <+dekar> the sticker says BMPM1 013
2014-03-19T21:05:50 < Thorn> I haven't seen that but once it gets into a morse error mode I sometimes have to power-cycle it, otherwise gdb hangs on a command
2014-03-19T21:05:55 <+dekar> besides the problem it works fine, but I always get annoyed having to unplug it :/
2014-03-19T21:06:51 < PaulFertser> OS X might be special, I think zyp's using Linux, the kernel, right?

2014-03-19T21:44:04 < Steffanx> it indeed works.. for one time. I think this is actually ~described on the wiki
2014-03-19T21:44:24 < Steffanx> Ah yes: "Note: On Mac OS X use the /dev/cu.usbmodem<somenumber>. Don't use the tty version of this device as this one will freeze gdb when it tries to open it." http://sourceforge.net/apps/mediawiki/blackmagicdebug/index.php?title=Main_Page
2014-03-19T21:46:01 < zyp> ah, of course
2014-03-19T21:46:18 < zyp> I was imagining dekar were running linux so I didn't think of that
2014-03-19T21:46:21 <+dekar> well, it doesn't freeze GDB
2014-03-19T21:46:45 <+dekar> but it was my bad for not reading the wiki :/
2014-03-19T21:47:15 < Steffanx> nah, its "hidden", perhaps it should be in the readme in the git repo.
2014-03-19T21:49:26 <+dekar> also from what I just read I feel like fixing the problem shouldn't be too hard: http://lists.apple.com/archives/usb/2009/Nov/msg00039.html

2014-03-19T22:13:50 < zippe> Ah, didn't realise you had a mirror
2014-03-19T22:13:59 < zyp> it's a bit outdated
2014-03-19T22:14:20 < zippe> Yes, I see that
2014-03-19T22:14:45 < zippe> I wanted to fix your mutexes
2014-03-19T22:14:48 < zyp> there, now it's up to date
2014-03-19T22:14:51 < zippe> sweet!
2014-03-19T22:16:15 < SlaveToTheSauce> mind adding the example branches?
2014-03-19T22:16:49 < zyp> you mean the laks_demo repo?
2014-03-19T22:17:34 < SlaveToTheSauce> probably
2014-03-19T22:17:59 < SlaveToTheSauce> yes
2014-03-19T22:18:21 < SlaveToTheSauce> huh thought they were in the same repo, whoops
2014-03-19T22:19:02 < zyp> for what purpose? forking an example to use as a basis for your own project?
2014-03-19T22:21:22 < SlaveToTheSauce> eh disregard that, i just failed at google a couple days ago and couldn't find you main site because of github and related stuff dominating the results
2014-03-19T22:21:34 < SlaveToTheSauce> but laks_demo works and i can remember that!
2014-03-19T22:22:00 < zippe> zyp: did you ever want thread preemption?
2014-03-19T22:22:09 < zippe> zyp: I realised that I was assuming you did
2014-03-19T22:22:25 < synic> what is laks?
2014-03-19T22:22:44 < zyp> zippe, I've been meaning to move the context switch to pendsv to fix that, I've just not had the need to yet
2014-03-19T22:23:05 < zippe> kk, so then what I was going to suggest for your mutex would be apropos
2014-03-19T22:23:11 < synic> like a scons system for building stm32 projects?
2014-03-19T22:23:24 < zippe> synic: it's zyp's tidy little c++ framework for stm32 stuff
2014-03-19T22:23:45 < zippe> Like a very, very light version of stm32plus
2014-03-19T22:23:58 < synic> supports all the families?
2014-03-19T22:24:16 < zyp> just the ones I've used
2014-03-19T22:24:17 < zippe> Think much lighter than tat
2014-03-19T22:24:43 < zippe> I'm mostly using it as an excuse to get better at slim c++
2014-03-19T22:24:52 < zyp> I made it mostly for my own use, and I add stuff to it as I need it
2014-03-19T22:25:18 < zyp> it originally started as part of my quadrotor controller firmware and grew out of it

2014-03-20T00:17:29 < zyp> hmm, cmsis-dap is actually using HID as a transport, apparently

2014-03-20T00:21:28 <+dekar> while I am all for using HID vendor specific devices, this sounds like it harshly limits the throughput for flashing firmwares etc
2014-03-20T00:22:16 < zyp> dunno, 64 kB/s doesn't sound like that harsh of a limit
2014-03-20T00:22:24 < Lux> why should hid be slow ? from what I read you can even get a few mbits of troughput on usb-cdc
2014-03-20T00:23:00 <+dekar> Lux, HID is limited to 64 bytes per packet and 1000 per second
2014-03-20T00:23:29 < zyp> on FS USB, using interrupt transport, that is
2014-03-20T00:24:05 <+dekar> well yeah it's not that harsh, but transferring a few MB would take quite a while

2014-03-20T00:25:13 <+dekar> right, micro frames :D
2014-03-20T00:26:25 < zyp> and even on FS HID can use control transfers to write more than one report per frame

2014-03-20T00:27:40 < zyp> but anyway, you also have the flash and swd bottlenecks, so it's not necessarily a problem anyway
2014-03-20T00:30:46 <+dekar> zyp, I recently had an interesting phenomenon. While flashing 200kB of firmware using my HID-bootloader I realised it was particularly slow and moving the mouse sped things up. That only happened on one particular PC, only when the device as well as the mouse were plugged into an external high speed hub and only on windows XP.
2014-03-20T00:31:17 < zyp> heh
2014-03-20T00:31:56 < zyp> would have been interesting seeing a trace of the traffic between the hub and host
2014-03-20T00:32:07 <+dekar> So I figure it has something to do with the HUB repacking full-speed packets, as well as the mouse generating additional traffic. But on the same system running Windows 7, or even XP without the hub the problem is gone.
2014-03-20T00:32:27 < zyp> yes, it's probably xp handling SPLIT transfers badly
2014-03-20T00:33:08 <+dekar> It kinda felt like those crypto applications telling you to move your mouse to generate entropy. On mouse movement the progress bar sped up :D

2014-03-20T01:24:04 < zippe> The only reason to use HID is because Microsoft want you to pay them to run any other kind of USB driver on Windows
2014-03-20T01:24:18 < zippe> And of course, using HID completely screws you on OS X
2014-03-20T01:26:14 <+dekar> zippe, how does it screw you on OSX? I'd say it's about the same user experience as on Windows.
2014-03-20T01:26:27 < aadamson> anyone got a minimum external components schematic for an F1 processor?  I know what the data sheets says, just wondering if anyone feels comfortable with something less than that for R's and C's?  (really just C's... the only R's are the ones on boot0 and boot1 I think
2014-03-20T01:27:07 < gxti> how much is a signing key suitable for windows drivers, anyway? if it's a regular code signing key it's probably not much
2014-03-20T01:28:04 <+dekar> gxti, you also have to get them to add it to Windows Update. Without that the User still has to manually install drivers. :/
2014-03-20T01:28:42 < gxti> sure but at least it's allowed, and it has a nice green checkmark on it with your name
2014-03-20T01:29:21 <+dekar> gxti, it still needs administrative permissions, doesn't it?
2014-03-20T01:29:30 < gxti> i would assume so
2014-03-20T01:30:20 < gxti> i think in any scenario where the user does not have admin privs, their administrator probably appreciates having the opportunity to find out what weird shit they're trying to plug in anyway
2014-03-20T01:32:08 <+dekar> Well, for us being able to run on locked down systems was a pretty big deal.

2014-03-20T01:54:26 < zyp> nice
2014-03-20T01:54:49 < dongs> dickstarter vid is ready
2014-03-20T01:56:52 < tp> dekar:  configuring udev rules is trivial, and a decent way to provide user auth for devices imho
2014-03-20T01:58:06 < zyp> zippe, I haven't had any huge problems using hidapi for stuff on OS X
2014-03-20T01:58:11 < zyp> but otherwise I agree
2014-03-20T01:59:14 < zyp> tp, why does a desktop computer need user auth for devices?
2014-03-20T01:59:46 < karlp> because I totally share my desktop comptuer with other people at the same time mang!
2014-03-20T02:00:24 < tp> zyp:  security
2014-03-20T02:00:40 < karlp> tp: I think you missed the point...
2014-03-20T02:00:51 < zyp> one of the problems with linux on the desktop is the silly focus on multi user systems everywhere
2014-03-20T02:01:52 < tp> Linux is a Unix clone, it does the same things Unix does, and Unix has been around since 1971
2014-03-20T02:02:35 <+dekar> tp, security lol, I recently had kernel panics when using 4 hidraw devices at the same time. Kernel code is buggy as hell. :/
2014-03-20T02:02:46 < tp> when you say 'silly focus', do you consider yourself a expert in this area, or that you have all the facts why things are the way they are ?
2014-03-20T02:03:07 < zyp> tp, so the point of linux is to give a 1971 era user experience?
2014-03-20T02:03:26 < tp> dekar:  you cant conjoin security and stability, they are totally different things
2014-03-20T02:04:40 <+dekar> tp, cause monolithic kernels are secure by design, oh wait...
2014-03-20T02:04:46 < tp> zyp:  I'm being serious, and I have heard all this stuff many times before
2014-03-20T02:05:33 <+dekar> tp, also I don't care about servers, but desktop distributions should totally come with reasonable (as in permissive) udev rules
2014-03-20T02:06:11 < tp> dekar:  kernel code can be buggy, but all kernels are not the same, for a thousand reasons. I recently reset my QNAP Linux RAID server after something like 1000 days, so it's kernel wasnt buggy
2014-03-20T02:06:18 < zyp> tp, I'm sorry, but I can't take «this is the way it has been since 1971, so we can't change it» as a serious argument
2014-03-20T02:06:47 < tp> dekar:  you can set up Linux so it's as insecure as windows if you like, it's just not done that way by default
2014-03-20T02:06:53 <+dekar> tp, so your kernel is free of bugs?
2014-03-20T02:07:14 < tp> which kernel, I have about 30 Linux kernels running here 24/7
2014-03-20T02:07:15 < Bird|ghosted> zyp: actually, multi-user home PCs are fairly common
2014-03-20T02:07:27 < englishman> dongs: leekspin?
2014-03-20T02:07:30 < englishman> perfect
2014-03-20T02:07:30 <+dekar> tp, the one you just referenced
2014-03-20T02:08:02 < Bird|ghosted> dekar: what are you dealing with btw?
2014-03-20T02:08:18 < tp> dekar:  thats a trick question, all software, except obsolete software has bigs
2014-03-20T02:08:21 < zyp> Bird|ghosted, in this context I'm talking multiple users remotely logged in at the same time, not multiple user accounts
2014-03-20T02:09:31 < tp> zyp:  multiuser systems are vital in the Linux area, and multiuser support is carefully designed in Linux
2014-03-20T02:09:41 <+dekar> Bird|ghosted, I'm not quite sure what you mean by "dealing with".
2014-03-20T02:09:45 < zyp> tp, exactly
2014-03-20T02:09:55 < Bird|ghosted> zyp: aaah.  well, that functionality actually has a use on the desktop (it's the same thing that makes Fast User Switching type functionality possible)
2014-03-20T02:10:02 < zyp> tp, and the notion that you can't change that for desktop systems is what I call silly
2014-03-20T02:10:10 <+dekar> tp, there surely is bug free software -.-"
2014-03-20T02:10:29 < Bird|ghosted> dekar: I mean, why was dealing with super-locked-down-stuff such a priority for you?
2014-03-20T02:10:31 < tp> dekar:  let me know when you find some
2014-03-20T02:10:43 <+dekar> Bird|ghosted, http://www.flexoptix.net/en/flexbox-v3-transceiver-programmer.html
2014-03-20T02:10:54 < zyp> Bird|ghosted, still irrelevant, surely you don't need to isolate device access between local users
2014-03-20T02:10:57 <+dekar> Bird|ghosted, browser controlled USB device
2014-03-20T02:11:10 <+dekar> Bird|ghosted, also B2B customers
2014-03-20T02:11:19 < tp> zyp:  you can change everything with Linux, it's not set in crumbly stone like mswindows
2014-03-20T02:11:56 < Bird|ghosted> zyp: :P what if you didn't want your kid to chew up all the printer paper?
2014-03-20T02:12:00 < gxti> dekar: i'm less sympathetic to wanting unprivileged access if it's for IT people to use :-)
2014-03-20T02:12:13 < tp> surely you don't need to isolate device access between local users .... ??? that depends on the device
2014-03-20T02:12:13 <+dekar> tp, that's why I suggested desktop distributions should ship reasonable udev rules
2014-03-20T02:13:07 < tp> dekar:  I think they do
2014-03-20T02:13:27 < tp> but our definition of 'reasonable' may differ
2014-03-20T02:13:41 < karlp> yeah, yours is based on 1971
2014-03-20T02:13:47 < tp> udev was designed to make reasonable device access possible
2014-03-20T02:13:52 < tp> mine ?
2014-03-20T02:13:53 <+dekar> tp, so why do they automatically mount USB drives for your logged in user? Isn't that a huge security problem?
2014-03-20T02:13:57 < tp> I didnt design Unix
2014-03-20T02:14:05 < Bird|ghosted> dekar: autoMOUNT is *NOT* a security hole
2014-03-20T02:14:07 < Bird|ghosted> autoRUN is
2014-03-20T02:14:20 < tp> Bird|ghosted:  exactly
2014-03-20T02:14:21 < karlp> Bird|ghosted: it is with hacked sd cards :)
2014-03-20T02:14:37 < tp> karlp:  explain ?
2014-03-20T02:14:39 < Bird|ghosted> the security issue on Windows is because a mass storage\ device can control the semantics of insertion
2014-03-20T02:14:49 <+dekar> Bird|ghosted, autoMOUNT is basically the same as allowing HID devices, you can communicate using both
2014-03-20T02:14:52 < zyp> tp, why? if I wanted to fuck up my friend's usb device and I don't have access to do it on his computer, I'll just unplug it and plug it into my own, all your pointless security goes down the drain
2014-03-20T02:14:58 < tp> Bird|ghosted:  agree, you clearly know *nix
2014-03-20T02:15:16 < zyp> then he'll punch me in the face to make sure I don't do it again, which actually works
2014-03-20T02:15:31 < tp> zyp:  are you trolling me or are you serious ?
2014-03-20T02:15:39 < gxti> not to mention that you can add options to mount to prevent execution, setuid, and device files
2014-03-20T02:15:42 < zyp> yes, I'm serious
2014-03-20T02:15:45 < gxti> i assume that's the default for automount
2014-03-20T02:15:51 < gxti> (the latter two anyway)
2014-03-20T02:16:15 < zyp> if you have physical access to a device, software security on the host side is pointless
2014-03-20T02:16:32 <+dekar> gxti, my point was that you can communicate with your USB device using mass storage, yet some of you guys think that communicating via mass storage is a security risk.
2014-03-20T02:16:45 <+dekar> *via HID is a risk
2014-03-20T02:17:02 < gxti> zyp: just because it is not possible to be perfect does not mean it is not worth making SOME attempt
2014-03-20T02:17:23 < gxti> security is about layers
2014-03-20T02:17:26 < zyp> gxti, the problem is that the attempt sacrifices usability
2014-03-20T02:17:27 < tp> zyp:  if you have access to hardware, security is usually much lessened, please show how 'fucking up your friends usb device' the way you have illustrated is different on *any* OS ?
2014-03-20T02:17:42 < zyp> tp, it's not
2014-03-20T02:17:55 < tp> zyp:  then why the Linux beef ?
2014-03-20T02:18:08 < zyp> I'm just arguing that your point about security is pointless
2014-03-20T02:18:22 < tp> ??
2014-03-20T02:18:22 <+dekar> tp, it's different on minix due to the lack of USB support, your hypothetical minix using friend wouldn't have an USB drive around :)
2014-03-20T02:18:32 < tp> dekar:  hahah
2014-03-20T02:18:53 < gxti> it won't be so funny when you get r00ted over the serial port!
2014-03-20T02:19:10 < tp> zyp:  you have chosen an example that isnt relevant, to prove your point, and thats not much use
2014-03-20T02:19:11 <+dekar> wait, it's "a USB drive" and not "an USB drive", right?
2014-03-20T02:19:27 < gxti> dekar: i don't really know what we're arguing about anymore
2014-03-20T02:19:37 < gxti> so let's all blame the us government and move on
2014-03-20T02:19:41 < gxti> as is customary
2014-03-20T02:20:13 < zyp> tp, ok, may I then suggest you provide an example of when the security does help?
2014-03-20T02:20:46 <+dekar> gxti, I still think the fact that you can freely communicate over the NUM-lock LED shows that USB restrictions are moot.
2014-03-20T02:20:51 < gxti> zyp: clarify which 'the security' you're talking about
2014-03-20T02:20:52 < tp> guys, windows users, I have heard all these arguments a million times since 1997, often it's because windows users don't have enough experience with Linux to understand why things are the way they are, the rest of the time, they are trolling me, either way, it's all water of a ducks back to me
2014-03-20T02:21:02 < zyp> gxti, usb device permissions
2014-03-20T02:21:30 < zyp> tp, I'm not a windows user
2014-03-20T02:21:32 < tp> Linux security is there for a very good reason, regardless whether you see why or not
2014-03-20T02:21:41 < gxti> zyp: because not letting unprivileged users interact with hardware by default is a pretty reasonable posture
2014-03-20T02:21:59 < tp> and dealing with security is a PITA for everyone, no argument there
2014-03-20T02:22:04 <+dekar> tp, it's not about linux security, but about distributions and their default settings, kernel is totally irrelevant here.
2014-03-20T02:22:08 < tp> it's a compromise
2014-03-20T02:22:13 < zippe> the *nix security model is woefully inadequate these days
2014-03-20T02:22:37 < gxti> zyp: remember 'users' isn't just the meatsack sitting at the keyboard, it's also all the single-purpose system daemons
2014-03-20T02:22:38 < zippe> The basic concepts hold, but the implementations are wildly out of date
2014-03-20T02:22:39 < tp> yeah, so windows users with 10EE99 windows only viruses keep saying
2014-03-20T02:22:54 < tp> zippe:  hardly
2014-03-20T02:22:59 <+dekar> tp, OSX has reasonable default settings, e.g. Ubuntu doesn't
2014-03-20T02:23:33 < zippe> tp: not 'hardly', very
2014-03-20T02:23:51 < tp> dekar:  Im no OSX expert, in fact I have zero OSX esperience, so I cant comment
2014-03-20T02:24:10 < zippe> tp: modern environments need far more expressive permissions controls
2014-03-20T02:24:29 < zyp> tp, remember that OS X is actually certified UNIX
2014-03-20T02:24:50 < zippe> tp: see e.g. the OS X sandbox
2014-03-20T02:24:50 < tp> All I can say is this: my 10 year old business has run ONLY Linux since it started. I sell around 300k in WiFI gear every year, and I have zero issues
2014-03-20T02:24:53 < Bird|ghosted> gxti: exactly
2014-03-20T02:25:13 < tp> every Wifi AP I sell, runs Linux
2014-03-20T02:25:22 < zippe> tp: all I can say is that I've been a kernel and security guy at Apple for over a decade
2014-03-20T02:25:23 < tp> every Wifi router and switch I sell, runs Linux
2014-03-20T02:25:29 < zippe> tp: I wrote the filesystem ACL code
2014-03-20T02:25:46 < zippe> tp: and I can't really talk about anything after that, but I think you get the picture
2014-03-20T02:26:05 < tp> zippe:  then I definitely wont argue with you re Apple software :)
2014-03-20T02:26:11 < zyp> tp, wifi aps/routers/switches are not desktop systems, and the distinction is important
2014-03-20T02:26:33 < tp> yes, I agree, I was just referring to Linux in general, apologies
2014-03-20T02:26:52 <+dekar> tp, http://techblog.vsza.hu/posts/Leaking_data_using_DIY_USB_HID_device.html
2014-03-20T02:26:54 < zippe> Inasmuch as "security" annoys users it's failed
2014-03-20T02:27:02 < tp> ???
2014-03-20T02:27:16 <+dekar> tp, that kind of attack works on any OS that supports USB keyboards
2014-03-20T02:27:28 < zippe> And inasmuch as you try to apply 1980s teletype security models to modern systems, you come up painfully short
2014-03-20T02:27:44 < tp> oh, ok, but youd need to get physical access to my systems ?
2014-03-20T02:27:57 < tp> lol
2014-03-20T02:28:30 <+dekar> tp, sure, but you'd need physical access to use ANY HID device to begin with, so why restrict them?
2014-03-20T02:28:48 < tp> interestingly when creating a Docker container the other day, it had to revert to teletype, so teletype options are still with us today
2014-03-20T02:30:10 < tp> debconf: falling back to frontend: Teletype
2014-03-20T02:30:18 -!- Bird|ghosted is now known as Bird|otherbox
2014-03-20T02:30:52 < tp> dekar:  the restriction is part of the security model, it's not personal to HID
2014-03-20T02:31:21 <+dekar> tp, sure it's personal to custom HID, keyboards and mice have exceptions!
2014-03-20T02:31:34 < tp> but, please, Im a Linux user and admin of my systems, I'm not a software person, Im a electronics technician
2014-03-20T02:31:48 < gxti> dekar: security does not end just because there is physical access
2014-03-20T02:31:58 < tp> dekar:  good point, I cant argue with that logic :)
2014-03-20T02:32:09 < Bird|otherbox> gxti: far easier said than done
2014-03-20T02:32:12 < Bird|otherbox> *far*
2014-03-20T02:32:30 <+dekar> gxti, didn't I explain that whitelisting some HID devices, but not all makes no difference in terms of security?
2014-03-20T02:32:46 < tp> dekar:  perhaps custom HID access will one day be as easy as keyboards and mice ?
2014-03-20T02:32:56 < gxti> i reject the claim that it makes *no* difference.
2014-03-20T02:33:12 < tp> if keyboards and mice access is easy now, why not other devices later ?
2014-03-20T02:33:22 <+dekar> tp, it is on Windows and OSX, that's why I argue desktop distributions should do the same.
2014-03-20T02:33:31 < gxti> not every security violation is a secret agent trying to exfiltrate state secrets through a numlock LED.
2014-03-20T02:33:45 < zyp> tp, custom HID access is pretty easy already, the biggest hurdle on linux is setting the permissions to get access to it
2014-03-20T02:33:55 < gxti> sometimes its' just someone trying to use a device their administrator hasn't approved. in fact, that's usually it.
2014-03-20T02:34:00 < tp> dekar:  maybe you're right
2014-03-20T02:34:37 < gxti> anyway if i haven't convinced you by now (and let's face it, i'm not really trying) i never will so i'm going to go find some food before i pass out
2014-03-20T02:34:43 <+dekar> gxti, so you're arguing it's security by USB-heuristics?
2014-03-20T02:34:50 < Bird|otherbox> yeah, oftentimes IA/IT droids throw giant wads of paper/flat "NO YOU CAN'T DO THAT" at people who *need* to use said device that the IT priesthood hasn't approvied
2014-03-20T02:34:54 < tp> dekar:  in any event, Linux admins can fix that on a box by box basis or using other tools on a whole company wide Linux deployment
2014-03-20T02:35:00 <+dekar> keyboards are probably harmless, unless they aren't
2014-03-20T02:35:05 < tp> hahahah
2014-03-20T02:35:31 < tp> unless dongs is attacking you armed with one of those old solid IBM keyboards
2014-03-20T02:35:38 < zyp> tp, it's not a matter of can/can't be fixed, it's a matter of the need to in the first place
2014-03-20T02:36:28 < tp> zyp:  so the argument is NOT that Linux cant make any device easy to access, but that theyre not easy to access NOW ?
2014-03-20T02:36:46 < tp> is impatience the issue here ?
2014-03-20T02:36:50 < tp> ;-)
2014-03-20T02:37:09 <+dekar> gxti, using your argumentation one could also argue users have no business to plug in USB keyboards to begin with, so disable any USB device, but those whitelisted!
2014-03-20T02:37:15 < zyp> also, when the easiest solution to missing privileges is to just run the script/program/whatever with root permissions, I'd argue that it overall reduces security
2014-03-20T02:37:40 < zyp> tp, yes
2014-03-20T02:38:00 < tp> I have a Olimex usb JTAG device that wasn't made easy to access with my UDEV rules, it took me about 5 minutes to fix that, I didnt see it as a big problem
2014-03-20T02:38:06 < zyp> when you are making something for others to use, you want them to be able to use it with minimal hassles
2014-03-20T02:38:19 < tp> zyp:  do you ?
2014-03-20T02:38:36 <+dekar> tp, for users without root permissions it is!
2014-03-20T02:38:53 < tp> Linux is GPL'd, it's not sold, there are no sales of Linux

2014-03-20T02:39:29 < Bird|otherbox> not directly at least
2014-03-20T02:39:37 < gxti> linux is sold quite frequently, the GPL does not prevent that
2014-03-20T02:39:40 < tp> dekar:  need some cough syrup ?
2014-03-20T02:40:00 < gxti> in fact it is expressly enumerated that you can, but of course you must also provide the source.
2014-03-20T02:40:01 < tp> gxti:  nope, devices using Linux are sold
2014-03-20T02:40:05 < Bird|otherbox> gxti: the enterprise distros are more a support contract than anything

2014-03-20T02:40:26 < gxti> so what? linux is sold. inside or not, support or not. i am merely objecting to the assertion.
2014-03-20T02:40:33 <+dekar> 50usd without support, I call that a sale!
2014-03-20T02:40:37 < gxti> maybe you meant to word it differently.
2014-03-20T02:40:42 < Bird|otherbox> not in the same way you sell a shrink-wrapped box :)

2014-03-20T02:40:54 < tp> you can only claim a reasonable fee for the media distribution
2014-03-20T02:40:56 < gxti> i knew what you meant too, it just seemms like such a starkly wrong thing to claim
2014-03-20T02:41:19 <+dekar> tp, you are legally allowed to sell GPL software
2014-03-20T02:41:20 < Bird|otherbox> I think we can all say 'GPL != shrinkwrap, no matter how much money is involved'
2014-03-20T02:41:22 < gxti> tp: that is specifically with respect to the source code, no constraints are made on the product itself
2014-03-20T02:41:43 < gxti> you can charge a million dollars for it as long as you charge no more than a nominal amount extra for the source
2014-03-20T02:41:50 < tp> I have sold thousands of boxes running linux, personally
2014-03-20T02:41:56 < zyp> tp, there is nothing in the GPL that forbids selling GPL software
2014-03-20T02:42:08 < gxti> this isn't a matter of opinion, it is a basic fact about licenses
2014-03-20T02:42:13 < tp> but they paid for the hardware, the Linux code is free and avail for dl
2014-03-20T02:42:20 < zyp> what you can't do is prevent the buyers from redistributing it
2014-03-20T02:42:30 <+dekar> tp, RHEL isn't free for download unless you pay for it
2014-03-20T02:42:42 < Bird|otherbox> at the end of the day, you have to acknowledge that software has no inherent marginal cost
2014-03-20T02:42:46 < tp> dekar:  you're not paying for the GPL component
2014-03-20T02:42:57 <+dekar> tp, sure you are
2014-03-20T02:43:05 < Bird|otherbox> dekar: then why does CentOS exist?
2014-03-20T02:43:08 < gxti> you don't really pay for any one component, it's not a la carte
2014-03-20T02:43:10 < tp> with RHEL, you pay for support and non GPL stuff (if they have any)
2014-03-20T02:43:23 <+dekar> Bird|otherbox, cause RHEL subscribers are compiling centos
2014-03-20T02:43:32 < zyp> Bird|otherbox, because you're allowed to redistribute GPL code
2014-03-20T02:43:53 <+dekar> tp, NO SUPPORT -> $50 https://www.redhat.com/apps/store/desktop/
2014-03-20T02:43:53 < Bird|otherbox> although, I really am getting tired of this argument
2014-03-20T02:44:14 < qyx_> btw i was always said what tp writes
2014-03-20T02:44:15 < gxti> arguing about non-embedded stuff on this channel is bad for my heart
2014-03-20T02:44:23 < Bird|otherbox> software naturally has $0 in marginal costs
2014-03-20T02:44:24 < gxti> why is everyone on the internet always so wrong :-[
2014-03-20T02:44:31 < qyx_> but, unrelated, can i abuse internal esd diodes to clamp higher voltage on stm32 inputs?
2014-03-20T02:44:40 < zyp> qyx_, yes
2014-03-20T02:44:48 < gxti> qyx_: sure why not, for sufficiently high impedance
2014-03-20T02:44:49 < qyx_> using series resistors of course
2014-03-20T02:44:53 < Bird|otherbox> I'd use an external BAT54 or two though
2014-03-20T02:44:55 < qyx_> ok \o/
2014-03-20T02:44:56 < zyp> qyx_, datasheet has values on maximum allowable injected current
2014-03-20T02:45:28 < qyx_> saved my life probably
2014-03-20T02:45:37 < qyx_> as i messed up my zener clamper
2014-03-20T02:45:59 < qyx_> and have connected zener and resistors the wrong way :X
2014-03-20T02:46:32 < zyp> now you're protected against large negative voltages, at least!
2014-03-20T02:47:38 <+dekar> :D
2014-03-20T02:49:57 < qyx_> hm, absolute maximum ratings lists +0mA as maximum injected current on 5V tolerant ports
2014-03-20T02:50:02 <+dekar> tp, http://www.gnu.org/philosophy/selling.html
2014-03-20T02:50:51 < zyp> qyx_, yes, FT pins don't have the normal ESD clamping diodes
2014-03-20T02:51:03 < qyx_> oh :(
2014-03-20T02:51:06 < zyp> datasheet even states that current injection is not possible

2014-03-20T02:56:25 < gxti> ;)
2014-03-20T02:56:39 < gxti> with sufficient voltage...
2014-03-20T03:03:16 <+dekar> I think the reference manual (STM32F4_DM00031020.pdf) states FT pins have protection diodes. See "Figure 25. Basic structure of a five-volt tolerant I/O port bit"
2014-03-20T03:06:35 < gxti> still it's not going to be the same steering structore as the non-FT pins so i would be somewhat uneasy about it

2014-03-20T06:11:28 < dongs> pushing on it or something?

2014-03-20T06:11:34 < zyp> looks like a sewing machine :p
2014-03-20T06:11:50 < GargantuaSauce> just a pressure gauge i'd say, push down to the expected height of the package
2014-03-20T06:11:59 < dongs> o
2014-03-20T06:12:01 < GargantuaSauce> and if it meets resistance, shit lifted off the pads?
2014-03-20T06:12:07 < GargantuaSauce> dunno
2014-03-20T06:12:20 < GargantuaSauce> zyp your usb stuff breaks if i send more than a few bytes at a time :(
2014-03-20T06:12:28 < zyp> what stuff?
2014-03-20T06:12:35 < GargantuaSauce> the cdc example
2014-03-20T06:12:57 < dongs> recompile wiht gcc
2014-03-20T06:13:04 < GargantuaSauce> that is what i am using
2014-03-20T06:13:11 < dongs> recompiler with newer gcc
2014-03-20T06:13:16 < zyp> GargantuaSauce, yes, there's no flow control on the in-pipe
2014-03-20T06:13:42 < englishman> now if only i could get those little arms to design and program shit for me
2014-03-20T06:14:00 < GargantuaSauce> well what confuses me is that the buffer is way bigger than the amount of data it chokes on
2014-03-20T06:14:31 < zyp> GargantuaSauce, it just loops back output packets to input, and doesn't check whether the previous packet is sent before writing another to the buffer
2014-03-20T06:15:10 < zyp> so if your host sends multiple OUT tokens without an IN token in between (or if the IN token comes too early) it'll fuck up
2014-03-20T06:15:50 < GargantuaSauce> right ok i see
2014-03-20T06:16:11 < zyp> you can work around it by throwing in a while(!usb.ep_ready(1)); before the usb.write()
2014-03-20T06:16:30 < GargantuaSauce> so it's just a question of the example being too oversimplified? not really a library issue?
2014-03-20T06:16:37 < zyp> of course that will lead to a deadlock if your host sends OUT tokens without sending IN tokens
2014-03-20T06:16:40 < zyp> yes
2014-03-20T06:17:00 < gxti> the weird probe thing must have been a current probe

2014-03-20T06:19:55 < GargantuaSauce> also i was not aware of virtual functions working with RTTI disabled
2014-03-20T06:20:00 < GargantuaSauce> that is still a bit of a head-scratcher
2014-03-20T06:20:22 < zyp> virtual functions doesn't have anything to do with RTTI
2014-03-20T06:20:41 < GargantuaSauce> well clearly
2014-03-20T06:20:49 < GargantuaSauce> i just didn't know that
2014-03-20T06:20:52 < zyp> virtual functions are implemented with a vtable
2014-03-20T06:21:09 < GargantuaSauce> yeah i thought the vtable was part of rtti i guess
2014-03-20T06:21:26 < zyp> RTTI is required for dynamic casts
2014-03-20T06:22:06 < zyp> to check whether it's the correct child class you're attempting to cast a parent pointer to

2014-03-20T06:32:12 < GargantuaSauce> welp i just confirmed that the issues i'm having with the other non-laks code are the fault of this machine's drivers
2014-03-20T06:32:25 < GargantuaSauce> sooo this may be an exercise in futility in any case!
2014-03-20T06:35:41 < GargantuaSauce> dongs this is your opportunity to rag on my choice of operating system! don't miss out!
2014-03-20T06:44:34 < dongs> lunix drivers, cool
2014-03-20T06:44:55 < GargantuaSauce> Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
2014-03-20T06:45:04 < GargantuaSauce> they are even taking credit for manufacturing the hardware!!
2014-03-20T06:47:29 < dongs> glad to know lunix still sucks in 2014
2014-03-20T06:48:04 < GargantuaSauce> just you wait, it'll be the year of the linux desktop!
2014-03-20T06:51:07 < dongs> yeah
2014-03-20T06:51:10 < dongs> in $year+1
2014-03-20T06:51:24 < dongs> googling "200x year of linux desktop" is hilarious
2014-03-20T06:52:02 < dongs> http://www.google.com/trends/explore#q=desktop%20linux
2014-03-20T06:52:06 < dongs> this is pretty much it.
2014-03-20T06:52:52 < gxti> no need for linux on the desktop, the desktop is dead. literally everyone does everything on their ipuds now.
2014-03-20T06:53:07 < dongs> thats their problem
2014-03-20T06:53:14 < PaulFertser> GargantuaSauce: if not GNU/Linux, then you can try OS X, some sane developers say it's ok for a desktop.
2014-03-20T06:53:30 < PaulFertser> GargantuaSauce: but better please report the issue with the kernel properly.
2014-03-20T06:53:53 < PaulFertser> GargantuaSauce: also, chances are if you downgrade to some older kernel (e.g. 3.0) that issue won't manifest itself there.
2014-03-20T06:54:14 < PaulFertser> GargantuaSauce: of course that's not a solution. If you can easily reproduce and get the stack trace, why not to report it?
2014-03-20T06:54:39 < GargantuaSauce> well i haven't gotten the oops since updating
2014-03-20T06:55:04 < GargantuaSauce> now a process just hangs on write()
2014-03-20T06:56:02 < GargantuaSauce> (and if i try and attach gdb to it, it hangs too)
2014-03-20T06:57:07 < dongs> ever since they changed kernel naming scheme its gone downhill
2014-03-20T06:57:11 < dongs> last usable kernel was like 2.6
2014-03-20T06:57:29 < dongs> the new shit is all garbage, senseless version numbers, everything broken, etc.
2014-03-20T06:57:45 < PaulFertser> GargantuaSauce: you can see /proc/<pid>/wchan to determine on what syscall it waits.
2014-03-20T06:58:04 < PaulFertser> GargantuaSauce: also, it might be a problem with your usb device side code, can't it be?
2014-03-20T06:58:28 < GargantuaSauce> well i've reproduced it with two very different cdc device implementations
2014-03-20T06:59:10 < PaulFertser> GargantuaSauce: you can use kernel usbmon module to gather a full log, and then show zyp for starters.
2014-03-20T06:59:22 < GargantuaSauce> and the same ones work fine on my ultrabook
2014-03-20T06:59:34 < PaulFertser> What's different in ultrabook?
2014-03-20T06:59:38 < GargantuaSauce> everything
2014-03-20T06:59:39 < dongs> real OS
2014-03-20T07:00:00 < PaulFertser> GargantuaSauce: I hope you're not using usb3 ports for your testing, are you?
2014-03-20T07:00:03 < GargantuaSauce> well not everything. probably same kernel, different chipset i think
2014-03-20T07:00:09 < GargantuaSauce> nope i made sure i was on a usb2 hub
2014-03-20T07:00:12 < GargantuaSauce> root hub i mean
2014-03-20T07:00:23 < dongs> why would anyone install lunix on a modern computer?
2014-03-20T07:00:32 < englishman> linux supports usb?
2014-03-20T07:00:39 < PaulFertser> dongs: because everything else sucks way more.
2014-03-20T07:00:54 < dongs> PaulFertser: billions of people using windows disagrewe
2014-03-20T07:01:13 < GargantuaSauce> i used to be a steadfast windows fan but it slowly wore down my enthusiasm
2014-03-20T07:01:14 < PaulFertser> dongs: billions of people listen to justin bieber or something.
2014-03-20T07:01:18 < zyp> dongs, I heard linux 3.11 for workgroups were pretty good
2014-03-20T07:01:53 < GargantuaSauce> anyway i will look into this properly when i have 5+ hours to put into debugging this crap
2014-03-20T07:02:12 < GargantuaSauce> for now, messing with a couple different implementations and driveby bitching will have to suffice
2014-03-20T07:02:21 < zyp> GargantuaSauce, have you checked the log on my usb stack?
2014-03-20T07:02:31 < GargantuaSauce> yes and nothing was obviously awry
2014-03-20T07:02:42 < PaulFertser> So both devices are using EHCI but one works and another doesn't. That might be a quirk in the chipset, manufacturers unfortunately all suck to some degree, breaking specs every now and then and not caring.
2014-03-20T07:02:59 < zyp> GargantuaSauce, pastebin it and I'll take a look
2014-03-20T07:03:01 < dongs> why would anyone use non-intel USB
2014-03-20T07:03:38 < zyp> maybe because that's what's in their computer, dunno
2014-03-20T07:03:41 < GargantuaSauce> i believe they are both intel
2014-03-20T07:03:44 < GargantuaSauce> but different generations
2014-03-20T07:04:33 < GargantuaSauce> http://pastebin.com/kt2bETdb sorry that's not all of it zyp, i moved back to my more complete implementation when i realized this was the same deal
2014-03-20T07:07:11 < zyp> uh, that's kinda hard to read :p
2014-03-20T07:07:27 < GargantuaSauce> how do you output it in a less terrible manner
2014-03-20T07:07:56 < zyp> if you have python support in your gdb, «source laks/gdb_plugins/rblog.py»
2014-03-20T07:08:00 < zyp> then «rblog usb_rblog»
2014-03-20T07:09:33 < GargantuaSauce> ok i will do that next time around...back to working with st's gross usb code for now but will go with laks in the long term
2014-03-20T07:09:50 < zyp> oh, I didn't realize you were working on F4
2014-03-20T07:10:14 < GargantuaSauce> ah yes that is an operative piece of information i probably could have shared
2014-03-20T07:11:52 < GargantuaSauce> in any case i think i am going to switch to ethernet for this stuff
2014-03-20T07:12:07 < GargantuaSauce> much more throughput and less latency jitter than usb/cdc
2014-03-20T07:13:11 < zyp> what is «this stuff»?
2014-03-20T07:13:51 < dongs> just make sure its gigE, for when military will want to buy your ethernet-controlled hexapod killbot
2014-03-20T07:14:12 < zyp> gigE is outdated, the new thing is dogE
2014-03-20T07:14:20 < GargantuaSauce> in short, robot control

2014-03-20T07:16:43 < GargantuaSauce> doing all the control on the pc and just throwing joint angles at the robot currently, and the serial link from pc to avr in that video is only 56k using pl2303
2014-03-20T07:16:47 < GargantuaSauce> not sure why i couldn't get it higher
2014-03-20T07:16:57 < dongs> > pl2303
2014-03-20T07:16:58 < dongs> thats why
2014-03-20T07:17:13 < GargantuaSauce> well i am not sure it isn't because i fucked up the avr board
2014-03-20T07:17:27 < GargantuaSauce> atmega8 on a perfboard
2014-03-20T07:17:30 < GargantuaSauce> fancy shit
2014-03-20T07:17:57 < GargantuaSauce> anyway so i went to replace that pl2303+avr trash with the f4 and here we are
2014-03-20T07:19:27 < GargantuaSauce> i know the f4 is ridiculously overkill for such an application, i have some f103 waiting for me to make a damn pcb
2014-03-20T07:19:43 < GargantuaSauce> but if usb isn't going to work i need to figure out ethernet and use a f*07 anyway
2014-03-20T07:20:20 < tylerdurden> hi, when i run my (stm32l152xb) code the execution goes to the else statement of SetSysClock() which is inside systeminit(), can some one explain how to solve it, the else statement contains { If HSE fails to start-up, the application will have wrong clock configuration. User can add here some code to deal with this error}
2014-03-20T07:21:09 < GargantuaSauce> one thing i've noticed is that even with usb vcp working "fine" on the other machine, there's still a huge buffer on the pc side and lots of jitter in the latency between a write() call in my application and it actually going over the wire

2014-03-20T08:06:58 < jpa-> tylerdurden: why are you worrying about configs? just debug the hardfault and see what causes it?
2014-03-20T08:08:49 < upgrdman> anyone know docs for new-lib nano are? for example, there's a printf... but where the fsck does it print to?
2014-03-20T08:08:57 < upgrdman> know where*
2014-03-20T08:09:47 < jpa-> it prints to stdout
2014-03-20T08:09:57 < jpa-> and stdout goes to wherever your _write() stub puts it
2014-03-20T08:10:04 < upgrdman> oh
2014-03-20T08:10:10 < tylerdurden> jpa: how to debug the hardfault it has only while(1) loop what to add in the function to debug it
2014-03-20T08:10:12 < jpa-> if you are using -lnosys, i have no idea where it goes :)
2014-03-20T08:10:17 < upgrdman> ok

2014-03-20T08:10:50 < jpa-> tylerdurden: what software?

2014-03-20T08:11:16 < upgrdman> jpa-: ok :) was hoping arm made a pdf or something. o well
2014-03-20T08:11:34 < jpa-> upgrdman: ARM? is newlib somehow related to ARM?
2014-03-20T08:12:22 < jpa-> tylerdurden: oh; I have never used IAR so i'm probably not much help.. but set a breakpoint in the hardfault handler and check SCB->CFSR for the fault status.. you will find more info in the ST's "Cortex-M3 programming manual"
2014-03-20T08:12:25 < tylerdurden> jpa : i am using stperipheral lib and hardfaulthandler is in stm32l1xx_it.c file

2014-03-20T09:14:10 < dongs> PonoMusic is more than just a high-resolution music store and player; it is a grassroots movement to keep the heart of music beating. PonoMusic aims to preserve the feeling, spirit, and emotion that the artists put in their original studio recordings.
2014-03-20T09:15:58 < dongs> With ultra-high resolution recordings (192kHz/24 bit), the difference between a PonoMusic digital file and an mp3 is about 30 times more data from which your player reconstructs the .song..

2014-03-20T09:23:38 < GargantuaSauce> All circuitry is zero-feedback. Feedback can only correct an error after it has occurred, which means that it can never correct for all errors. By using proprietary ultra-linear circuitry with wide bandwidth and low output impedance, there is no need for unnatural sounding feedback.

2014-03-20T12:33:57 < dongs> oh.
2014-03-20T12:33:59 < dongs> I *thought* that looked like an odroid.
2014-03-20T12:34:38 < dongs> We produced and tested our circuit board vigorously to ensure we will be delivering a quality product. The circuit board has to be manufactured from ground up. First, the circuit board needs to be fabricated. Once complete, the board will have its components mounted by machine. Finally, the board will go through a "reflow oven" to heat up the solder and join the parts to the board.

2014-03-20T13:04:00 < dongs> probably.. for the power interface
2014-03-20T13:04:01 < jpa-> __rob: for the power interface registers
2014-03-20T13:04:08 < __rob> which ones are they ?

2014-03-20T13:04:14 < jpa-> maybe the PWR ones?
2014-03-20T13:04:28 < __rob> ohh yea
2014-03-20T13:04:30 < __rob> sorry
2014-03-20T13:05:50 < __rob> out of interest, what happens if I try to configure a peripheral without the clock enabled ?
2014-03-20T13:05:58 < dongs> nothing
2014-03-20T13:06:09 < dongs> the same thing happening to Cyric right now :)
2014-03-20T13:08:21 < jpa-> __rob: the lines will wiggle but the registers won't toggle
2014-03-20T13:08:48 < __rob> ok. I have another question about the various locking registers to protect from parasitic writes
2014-03-20T13:08:56 < __rob> when is this expected to happen ?
2014-03-20T13:09:15 < jpa-> when everything goes wrong
2014-03-20T13:09:20 < __rob> I was assuming on startup, but by the time the instruction is executed to lock the registers, this would have already happened. no?
2014-03-20T13:09:42 < jpa-> no, it more easily happens if you call some corrupted function pointers
2014-03-20T13:09:43 < __rob> ohh, so when the cpu starts randomly executing due to some bad code ?
2014-03-20T13:09:47 < jpa-> yes
2014-03-20T13:09:49 < __rob> yea, ok
2014-03-20T13:10:03 < jpa-> for example, calling a virtual function on a null C++ object is a great way to do it
2014-03-20T13:10:13 < jpa-> because it will just take a random interrupt from the NVIC table and execute that
2014-03-20T13:10:16 < __rob> so surely at this point a reset is in oder anyway ?
2014-03-20T13:10:29 < __rob> I mean.. is this just to stop you bricking the actual hardware
2014-03-20T13:10:29 < jpa-> yes
2014-03-20T13:10:40 < jpa-> well more than just bricking hardware
2014-03-20T13:10:43 < __rob> as from a software point of view, its over at that point anyway..
2014-03-20T13:10:47 < jpa-> usually it is used for avoid bricking the user
2014-03-20T13:11:00 < jpa-> for example, if your processor is controlling a car acceleration pedal..
2014-03-20T13:11:00 < dongs> wat are you guise  talkin about
2014-03-20T13:11:05 < __rob> yea :)

2014-03-20T14:15:49 < Cyric> maybe they are predictable under a different point of view :)
2014-03-20T14:16:07 < tylerdurden> some times the port interrupt works and some times it doesn't
2014-03-20T14:16:47 < jpa-> maybe you don't initialize your structures! (hey, if i keep repeating this to every stdperiph user, i'll be right eventually)
2014-03-20T14:17:08 < Cyric> ahah
2014-03-20T14:17:37 < jpa-> but it is actually a very nasty problem to hit with stdperiph.. if you do not initialize some fields, they will contain random data from RAM and behaviour will be very confusing
2014-03-20T14:17:50 < jpa-> other good hints: enable the debug checks in stdperiph
2014-03-20T14:18:23 < Cyric> is your code working with other clock such as MSI?

2014-03-20T14:24:21 < tylerdurden> is it ok if we use only internal clks HSI , does it cause any problem in usart, i heard that internal clocks are not perfect.
2014-03-20T14:24:46 < karlp> it's fine
2014-03-20T14:26:17 < Cyric> well i had some problems by using HSI and USART in the L version
2014-03-20T14:26:29 < karlp> you don't have ADC working either... :)
2014-03-20T14:26:36 < Cyric> ahaha
2014-03-20T14:26:37 < Cyric> right
2014-03-20T14:26:46 < karlp> but I'm shipping product using the usart on the L1 with hsi :)
2014-03-20T14:27:24 < Cyric> are you using std_peripheral?
2014-03-20T14:28:08 < karlp> no way
2014-03-20T14:28:29 < Cyric> there are no trubble on clock accuracy... the only problem is using the HSI with standard pheripheral
2014-03-20T14:29:09 < Cyric> basically when you set HSI as source it will change also your BAUD RATE of the USART interface
2014-03-20T14:29:11 < Cyric> :D
2014-03-20T14:29:27 < karlp> pretty sure you were told what you were doing wrong there.
2014-03-20T14:29:44 < Cyric> yapp
2014-03-20T14:29:57 < karlp> if you tell the system that you're using HSE at Ymhz, and you actually use HSI at XMhz, then what on earth were you expecting was going to happen?
2014-03-20T14:31:24 < Cyric> well the difference for me was between HSI and MSI that are both internal and in someway i was expecting that the library were smart enought to understand which one i was using...
2014-03-20T14:31:36 < Cyric> but i fixed that
2014-03-20T14:31:38 < Cyric> :)
2014-03-20T14:32:14 < tylerdurden> karlp: in the stperipheral libs if we change the clock to Xmhz should we make changes in usart baud rate or its adjusted internally in the config functios
2014-03-20T14:35:34 < Cyric> afaik, if you change the clk source different from MSI, than it will change your baud rate... for fixing that, you have to tell the MCU what frequency are you using...
2014-03-20T14:36:40 < karlp> tylerdurden: not using stdperiphlib, don't know, but _I_ would never want to call any sort of apifunction set_baud(49326) if I really wanted set_baud(115200) or anything absurd like that
2014-03-20T14:41:13 < qyx_> jpa-: works now, it fails with OSPEED_100M

2014-03-20T15:17:37 < Cyric> I am usign the MSI as clock source, for for ADC you still need to enable also the HSI

2014-03-20T15:17:47 < englishman> says who??
2014-03-20T15:18:10 < karlp> hrm, I thought adc always had it's own clock,
2014-03-20T15:18:22 < jpa-> karlp: it has to come from somewhere :)
2014-03-20T15:18:22 < karlp> so that you _could_ be on MSI

2014-03-20T19:46:14 < SlaveToTheSauce> do you have a usable debugger?
2014-03-20T19:46:30 < Lux> yeah I use keil with a discovery board
2014-03-20T19:47:54 < SlaveToTheSauce> well stick a breakpoint in the hardfault handler (or busyloop in it and break manually or whatever)
2014-03-20T19:48:32 < SlaveToTheSauce> all the registers get pushed onto the stack when there's a fault i believe so you can take a peek at them to determine application state
2014-03-20T19:48:53 < SlaveToTheSauce> also look at the SCB registers
2014-03-20T19:51:06 < SlaveToTheSauce> there are a lot of different ways to get a hardfault. the one i've run into the most is stupid stack-smashing bugs
2014-03-20T19:52:12 < Lux> hmm seems like it's due to some compiler optimisation, when I set it to -o0 it works
2014-03-20T19:52:18 < Lux> thanks I'll try that
2014-03-20T19:53:17 < SlaveToTheSauce> breaking when optimizations are enabled is exactly that happens to me when i do something dumb and break the stack
2014-03-20T19:53:30 < SlaveToTheSauce> make sure no functions are implicitly declared and then called with more parameters, etc
2014-03-20T19:54:20 < zyp> due to optimization? unless your compiler is buggy, the problem is not caused by the optimization, the problem is caused by you making assumptions that aren't true
2014-03-20T19:54:47 < SlaveToTheSauce> yeah

2014-03-20T21:19:29 < Lux> found it: http://bcas.tv/paste/results/QHQxRa34.html
2014-03-20T21:20:20 < Lux> any ideas how I can change the packed statement to make it more standard conform ?
2014-03-20T21:20:35 < Lux> it crashes right here: USB_OTG_WRITE_REG32( fifo, *((__packed uint32_t *)src) );
2014-03-20T21:21:30 < Lux> it's just a macro: #define USB_OTG_WRITE_REG32(reg,value) (*(__IO uint32_t *)reg = value)
2014-03-20T21:21:44 < SlaveToTheSauce> so what's the value of src
2014-03-20T21:22:34 < SlaveToTheSauce> and fifo i suppose!
2014-03-20T21:22:36 < Lux> src is a buffer with lenght len that is written to the usb bus I guess
2014-03-20T21:22:46 < SlaveToTheSauce> i would verify that they are both valid pointers
2014-03-20T21:23:15 < SlaveToTheSauce> alignment might also be a concern
2014-03-20T21:23:35 < Lux> yeah that's most likely the issue
2014-03-20T21:23:49 < Lux> as it works without optimisation
2014-03-20T21:25:04 < gxti> assuming src is some random uint8 buf, it's probably alignment
2014-03-20T21:26:29 < Lux> any ideas how I can fix that ? the alignment paramater in that function is ignored :/
2014-03-20T21:27:02 < gxti> can fifo handle byte writes?

2014-03-20T21:39:44 < Lux> good question, I honestly have no idea :-)
2014-03-20T22:05:59 < Lux> fixed it:
2014-03-20T22:06:06 < Lux> temp = (uint32_t)(*(src+3) << 24) | (uint32_t)(*(src+2) << 16) | (uint32_t)(*(src+1) << 8) | (uint32_t)(*src); ^^
2014-03-20T22:06:21 < Lux> just used a temp var to make a uint32 out of the buffer
2014-03-20T22:06:41 < Lux> not nice, but it works
2014-03-20T22:06:47 < gxti> heh. i would at least give byte writes a try, it would be less ugly than that and no slower :p
2014-03-20T22:07:19 < gxti> but whatever works i guess
2014-03-20T22:09:58 < Lux> right, plus it's allways rather hard finding out what that stuff does if you haven't written it yourself

2014-03-21T01:03:15 < ds2> is avoiding the 0.6V drop on the load the reason people use a PNP transistor for load switching?

2014-03-21T01:07:42 < gnomad> you have the same drop regardless of whether you use npn or pnp
2014-03-21T01:08:26 < gnomad> pnp allows for high side drive, useful when you need to switch a ground-connected device.
2014-03-21T01:08:30 < ds2> hmm?
2014-03-21T01:08:44 < ds2> with a PNP, the load is on the connector so the load only sees a drop of Vsat
2014-03-21T01:08:56 < ds2> with a NPN, the load is on the emitter so it sees Vf losses
2014-03-21T01:09:01 < ds2> s/connector/collector/
2014-03-21T01:09:05 < ds2> is that wrong?
2014-03-21T01:09:19 < gnomad> go back and read up on your transistor basics.
2014-03-21T01:09:19 < ds2> this is assuming the load is ground connected
2014-03-21T01:09:37 < ds2> just trying to toggle power to a load from a microcontroller
2014-03-21T01:09:52 < qyx_> so use pfet, it is modern!
2014-03-21T01:10:01 < gnomad> http://www.w9xt.com/page_microdesign_toc.html
2014-03-21T01:11:00 < ds2> PFETs are easy but too many parameters to worry about if the logic voltage drops

2014-03-21T01:38:07 < Lux> Fleck: yep, lots of useful stuff for beginners :)
2014-03-21T01:39:48 < Lux> now I finally have a satisfying solution for my problem: memcpy http://bcas.tv/paste/results/cAFYZX90.html
2014-03-21T01:42:16 < zyp> that's assuming your memcpy copies data in a linear fashion, which isn't necessarily true
2014-03-21T01:42:56 < Lux> zyp: when isn't it true ?
2014-03-21T01:45:39 < Lux> or when could I run into problems with it ? so far it works well
2014-03-21T01:46:23 < Lux> I'm not really familiar with what you mean, non-linear means it messes up the alignment ?
2014-03-21T01:48:05 < zyp> writing bytes incrementing from the first to the last
2014-03-21T01:49:47 < zyp> a compliant memcpy implementation is allowed to start at the end, for instance, and decrement the pointer, instead of starting at the beginning and incrementing
2014-03-21T01:50:41 < zyp> and you're writing into a fifo which means that the address you're writing to is ignored and the fifo simply expects you to write the data from start to end
2014-03-21T01:51:36 < Lux> makes sense, does that mean I could just write to the fifo in 1 byte increments ?
2014-03-21T01:52:30 < Lux> I wasn't sure about that, because the reference manual clearly states 32-bit registers used for the fifo
2014-03-21T01:53:02 < Lux> from what I understand I have to write 4 bytes into that register and then it gets pushed into the fifo
2014-03-21T01:54:11 < zyp> unsure, I believe the manual for the synopsys core states that you can use all kinds of accesses
2014-03-21T01:55:28 < zyp> anyway, if memcpy works, just stick with it
2014-03-21T01:56:06 < Lux> i will, thanks for the heads up

2014-03-21T02:47:20 < GargantuaSauce> it is not very surprising that it's shitty tbh, i kinda assumed that when i glanced over the protocol
2014-03-21T02:48:52 < GargantuaSauce> on the other hand there aren't really any other self-contained servos with comparable specs and features anywhere i that price range are there
2014-03-21T02:50:32 < GargantuaSauce> well no superior immediate alternatives
2014-03-21T02:50:39 < GargantuaSauce> what is your application, anyway?
2014-03-21T02:52:18 < upgrdman> could a hobby servo + tapping the pot wiper for feedback work in your application?
2014-03-21T02:53:20 < upgrdman> k
2014-03-21T02:56:09 < GargantuaSauce> the avr8 is funnier
2014-03-21T02:56:21 < GargantuaSauce> the new lines use some cortex-m3 though apparently
2014-03-21T02:57:05 < GargantuaSauce> looks like atmega8 to me
2014-03-21T02:57:46 < GargantuaSauce> has a massive 1k of sram
2014-03-21T03:00:16 < GargantuaSauce> http://www.youtube.com/watch?v=UNjIb2IqFOo you think?
2014-03-21T03:01:06 < GargantuaSauce> i dunno i'd say a reasonably powerful mcu for such a thing is a good idea
2014-03-21T03:01:43 < GargantuaSauce> so it can pull its weight and still have a lot of leeway for the serial control interactions
2014-03-21T03:01:53 < GargantuaSauce> also onboard signal processing etc
2014-03-21T03:01:54 < GargantuaSauce> yeah
2014-03-21T03:02:10 < gxti> i design angrily, much better than nicely
2014-03-21T03:02:32 < GargantuaSauce> rage is the best emotion for driving development for sure
2014-03-21T03:05:15 < GargantuaSauce> probably can
2014-03-21T03:05:46 < GargantuaSauce> yeah
2014-03-21T03:06:26 < GargantuaSauce> lin can only do 20 kbts
2014-03-21T03:06:28 < GargantuaSauce> kbits
2014-03-21T03:07:41 < GargantuaSauce> well actually i'd say maybe i'd prefer rs-485
2014-03-21T03:08:49 < GargantuaSauce> no idea
2014-03-21T03:09:00 < gxti> no arbitration
2014-03-21T03:09:17 < GargantuaSauce> differential signalling is certainly preferable though
2014-03-21T03:09:28 < GargantuaSauce> perhaps can with the physical layer of rs-485 would be ideal i dunno
2014-03-21T03:09:39 < gxti> CAN defines what happens when two nodes talk at once, RS485 leaves that as an exercise to the programmer

2014-03-21T05:11:38 < zyp> "Hole dimensions differ according to the kind of PC board and piercing method. If PC boards made of hard material are used, the hole dimensions should be larger. The dimensions above should serve as a guideline. Contact JST for details."
2014-03-21T05:11:42 < zyp> very useful.
2014-03-21T05:13:41 < zyp> current hole size is 0.9mm, wonder if going to 1mm would be enough
2014-03-21T05:13:45 < zyp> dongs, what do you think?
2014-03-21T05:13:50 < zyp> this is about those fucking connectors
2014-03-21T05:15:30 < dongs> yea
2014-03-21T05:15:31 < dongs> sure
2014-03-21T05:15:47 < dongs> 0.9+plating = probably enough t obe annoying
2014-03-21T05:15:50 < dongs> whats the pin diameter?
2014-03-21T05:15:54 < dongs> +- to max
2014-03-21T05:16:34 < zyp> pin diameter is not the problem, the pins are bent so they can snap into the board and hold the connector until it's soldered
2014-03-21T05:17:39 < zyp> pin diameter is 0.64mm
2014-03-21T05:18:41 < dongs> ok then 1mm hopefully ok
2014-03-21T05:19:15 < zyp> 2-pin connectors are already 1mm per spec, and they have no problems
2014-03-21T05:19:23 < dongs> ok
2014-03-21T05:22:15 < zyp> hmm, how do I rerun a cam job I've already created?
2014-03-21T05:22:20 < zyp> I haven't figured out that yet :p
2014-03-21T05:23:42 < gxti> in what
2014-03-21T05:24:04 < zyp> altium, I want to create a new drill file
2014-03-21T05:24:13 < zyp> I already have a camtastic file
2014-03-21T05:24:26 < gxti> are you using an 'output job'?
2014-03-21T05:24:42 < zyp> wouldn't that be the camtastic file?
2014-03-21T05:24:58 < gxti> oh never mind, you mean camtastic bullshit. i never bothered figuring it out because it's so clunky.
2014-03-21T05:25:27 < zyp> true, last time I had to reexport a design I just deleted previous file and reexported it
2014-03-21T05:25:40 < zyp> but there must be a better way :p
2014-03-21T05:25:46 < gxti> that's exactly what you should do if it's generated straight from pcb.
2014-03-21T05:25:55 < zyp> oh
2014-03-21T05:26:05 < dongs> zyp, you need to check output jobs thing,, and drag drill + gerber shit to outputs
2014-03-21T05:26:06 < gxti> in fact i always nuke the entire output directory because one time i managed to not export inner layers of a 4 layer pcb and the result was a coaster
2014-03-21T05:26:09 < dongs> i dunno either it looked super obtuse
2014-03-21T05:26:40 < zyp> but why does the camtastic files get added as source files then?
2014-03-21T05:26:59 < gxti> because otherwise nobody would look at camtastic, probably. you can turn that off.
2014-03-21T05:27:23 < gxti> create an output job file and put all your gerber/drill settings in there so you can just do it all in one click.
2014-03-21T05:27:29 < gxti> also so you don't fuck it up
2014-03-21T05:27:42 < zyp> oh
2014-03-21T05:27:43 < dongs> was tehgre a good way to make output job
2014-03-21T05:27:49 < dongs> so far only way i found was file-.smartpdf
2014-03-21T05:27:53 < dongs> then click throug hthat and that adds job shit
2014-03-21T05:28:05 < dongs> hm i didnt check file->:new haha
2014-03-21T05:28:19 < dongs> ya, its there.
2014-03-21T05:28:20 < gxti> ya
2014-03-21T05:28:21 < dongs> ok im dum
2014-03-21T05:28:37 < zyp> ok, I'll try that
2014-03-21T05:28:51 < gxti> i use folder output with gerber/drill, BOM, and STEP, and a PDF output with schematic print, DRC, and ERC
2014-03-21T05:29:00 < zyp> oh, wait, now I remember I did this for a workpcb :p
2014-03-21T05:29:14 < gxti> once you set up the job file you can copy it between projects

2014-03-21T05:33:19 < dongs> on USB or whatnot
2014-03-21T05:33:25 < zyp> yes
2014-03-21T05:33:28 < dongs> if so, you need to check G85 checkbox on drill output

2014-03-21T05:33:40 < zyp> I know, you complained about it before

2014-03-21T05:33:44 < dongs> good
2014-03-21T05:34:15 < zyp> anyway, the only change is PCB1-RoundHoles.TXT, rest is unchanged from the previous gerber set
2014-03-21T05:34:39 < zyp> can I just send you the changed file, or should I pack up everything again?
2014-03-21T05:34:50 < dongs> just changed should be oK

2014-03-21T05:37:53 < dongs> kk, ill submit it today
2014-03-21T05:38:24 < zyp> great, thanks
2014-03-21T05:39:11 < dongs> you gonna do same quantity assembly? or less
2014-03-21T05:39:34 < dongs> i remember you said you wonly wanted 100 or something this time
2014-03-21T05:39:46 < zyp> huh?
2014-03-21T05:40:00 < dongs> i duno
2014-03-21T05:40:19 < dongs> so ~200-ish or whatever like last time?
2014-03-21T05:40:26 < zyp> last time was 112
2014-03-21T05:40:29 < dongs> or that
2014-03-21T05:40:33 < zyp> first time too
2014-03-21T05:40:35 < dongs> oh, then never mind. i must be stoned
2014-03-21T05:40:45 < zyp> and yes, same again
2014-03-21T05:40:48 < dongs> kk
2014-03-21T05:41:41 < zyp> third run should last longer, I don't expect anyone to buy 75 at once again in the near future :p
2014-03-21T05:41:49 < dongs> right
2014-03-21T05:43:04 < dongs> should i bother china for parts today or next week later?
2014-03-21T05:44:26 < zyp> doesn't matter to me, as long as lack of parts doesn't hold up assembly
2014-03-21T05:44:50 < dongs> hm it takes < 1 week for fr4 panel
2014-03-21T05:44:53 < dongs> alright, lemme do it now then
2014-03-21T05:45:34 < zyp> guess I should do digikey again then
2014-03-21T05:46:14 < zyp> I guess you sorted out the usb connector stuff since you didn't mention it again?
2014-03-21T05:46:20 < dongs> yeah, i got 500 in kr
2014-03-21T05:46:26 < dongs> ~270 being used
2014-03-21T05:46:41 < dongs> so remainder is yours
2014-03-21T05:47:50 < dongs> i did end up emptying the one reel that supplier had over last few months, so its different place this time, but same stuff.
2014-03-21T05:48:04 < zyp> ok, then there's just XH from digikey like before?

2014-03-21T08:31:18 < dongs> wait
2014-03-21T08:31:23 < dongs> you didnt hookup jtag to stm io?
2014-03-21T08:31:54 < dongs> i guess for proto it doesnt matter. could do it later. so you can load config crap over stm32 later on
2014-03-21T08:32:27 < zyp> I'm not indending to load config over jtag, I'm intending to load it over the parallel interface
2014-03-21T08:32:46 < dongs> haha..
2014-03-21T08:33:29 < zyp> since I'm hooking it to FSMC anyway, I've hooked it up to load config in parallel slave mode
2014-03-21T08:33:47 < zyp> otherwise I'd do slave serial, still not jtag
2014-03-21T08:35:57 < emeb_mac> slave serial is pretty easy
2014-03-21T08:36:06 < emeb_mac> I do that thru a spi port
2014-03-21T08:37:08 < zyp> yes, I'm just not sure I have any spi ports available on the FSMC headers on the board
2014-03-21T08:37:36 < zyp> hmm, I haven't hooked up prog_b/done yet

2014-03-21T21:36:01 < chris_99> i'm just wondering i've got an stm32f429, and am using gentoo, is there a simple way to install a toolchain for it
2014-03-21T21:36:29 < PaulFertser> chris_99: binary toolchain from gcc-arm-embedded
2014-03-21T21:36:38 < chris_99> sweet, thanks
2014-03-21T21:36:39 < PaulFertser> chris_99: or self-compile using their sick build script.
2014-03-21T21:36:52 < chris_99> where do i get that from
2014-03-21T21:37:03 < chris_99> the build script i mean
2014-03-21T21:37:08 < PaulFertser> Their launchpad page, sources tarball.
2014-03-21T21:37:09 < PaulFertser> iirc

2014-03-21T22:01:07 < SlaveToTheSauce> openocd
2014-03-21T22:04:03 < chris_99> oh neat, didn't know i could use that for this
2014-03-21T22:06:36 < SlaveToTheSauce> wait that was a bit of a reflex response...you do mean on the discovery board right?

2014-03-21T22:33:24 < chris_99> so i've just programmed something seemingly the flashing led example from http://www.libopencm3.org   (examples/stm32/f4/stm32f4-discovery/random)
2014-03-21T22:33:39 < chris_99> using openocd --file ~/Repositories/code/tcl/board/stm32f429discovery.cfg -c "program random.elf verify reset"
2014-03-21T22:33:51 < chris_99> but i don't see any flashing leds

2014-03-21T22:40:08 < SlaveToTheSauce> that example is made for the f407 discovery
2014-03-21T22:40:08 < karlp> what does the readme in "random" say it does?
2014-03-21T22:40:11 < SlaveToTheSauce> the LED pins are different
2014-03-21T22:40:48 < SlaveToTheSauce> wait no I lied
2014-03-21T22:41:44 < SlaveToTheSauce> double-no, that is indeed the case
2014-03-21T22:41:59 < karlp> chris_99: just flashed thatto my f4 disco board, blinks fine,
2014-03-21T22:42:07 < karlp> but that's nto a f429 board...
2014-03-21T22:42:46 < chris_99> hmm maybe it's diff. pins then, i'll try the usb example
2014-03-21T22:42:49 < SlaveToTheSauce> f4disco has them on gpiod 12-15, f429disco has them ooonn G13-14, B13, C5
2014-03-21T22:43:06 < karlp> chris_99: randomly trying different eexamples is probably not a recipe for happiness
2014-03-21T22:43:24 < chris_99> true
2014-03-21T22:43:46 < chris_99> ah cheers SlaveToTheSauce i'll change it thn
2014-03-21T22:45:39 < chris_99> hmm gpio_toggle(GPIOD, GPIO12 | GPIO13 | GPIO14 | GPIO15);
2014-03-21T22:45:41 < chris_99> it says that
2014-03-21T22:45:57 < chris_99> doesn't that mean it should work
2014-03-21T22:46:28 < SlaveToTheSauce> none of D12-15 are on LEDs on the 427 discovery
2014-03-21T22:47:26 < chris_99> oh so i change GPIOD to what sorry
2014-03-21T22:49:13 < SlaveToTheSauce> well you should be looking in the discovery board's documentation to learn what GPIOs are tied to which peripherals
2014-03-21T22:49:17 < SlaveToTheSauce> but i also told you above
2014-03-21T22:49:39 < SlaveToTheSauce> note that where the gpio is initialized in the example also needs to be updated

2014-03-22T03:05:47 < Sync__> I'm dumb
2014-03-22T03:05:48 < wine-tails> why people like portable batteriys
2014-03-22T03:05:53 < Sync__> it says it a bit higher
2014-03-22T03:06:04 < Sync__> but it is called tdts there
2014-03-22T03:06:09 < Sync__> so no wonder find would not get it

2014-03-22T03:09:41 < Sync__> I just found it
2014-03-22T03:10:00 < Sync__> but the st cocks called it tdts instead of fdts

2014-03-22T03:34:54 < dongs> in a pnp, collector-emitter saturation voltage higher is better or lower
2014-03-22T03:34:55 < Thorn> http://imgur.com/gallery/xEblxiz wtf
2014-03-22T03:36:37 < Thorn> lower absolute value is better iirc
2014-03-22T03:37:13 < dongs> its like negative
2014-03-22T03:37:41 < englishman> what are you doing
2014-03-22T03:37:56 < dongs> just checking if I can replace this odd chink pnp with a 3906
2014-03-22T03:38:06 < dongs> ill jsut do it and deal with it if it doesnt work
2014-03-22T03:38:12 < englishman> if you dont care, answer is yes

2014-03-22T04:26:54 < dongs> well, got this shit handplaced somehow.
2014-03-22T04:26:59 < dongs> quite a bit more annoying than in dicktrace
2014-03-22T04:27:18 < dongs> dicktrace I ctrl+f, type value, and it gives me a clickable list i can just go down as I place stuff
2014-03-22T04:27:47 < emeb_mac> huh - never tried that
2014-03-22T04:27:54 < dongs> in pcb
2014-03-22T04:28:06 < dongs> just gotta check 'value' box, and type 100nF or whatever
2014-03-22T04:28:18 < dongs> and you can doubleclick each entry, and it highlights it
2014-03-22T04:28:22 < emeb_mac> in altium now?
2014-03-22T04:28:23 < dongs> so you know where to handplace
2014-03-22T04:28:31 < dongs> in altium there's nothing similar
2014-03-22T04:28:39 < dongs> the find similar shit works but it doesnt give a "list"
2014-03-22T04:28:48 < dongs> you can highlight on board etc, but thats anoying and you dont get total count
2014-03-22T04:28:53 < dongs> so I dunno how many caps to drop down for example
2014-03-22T04:29:02 < emeb_mac> right
2014-03-22T04:29:33 < Thorn> dicktrace can calibrate your printer for toner transfer. pretty sure altium can't do that either lol

2014-03-22T07:28:20 < upgrdman> DAMN IT! thanks! :)
2014-03-22T07:28:36 < upgrdman> an hour of f'ing around because of this. lol
2014-03-22T07:28:41 < PaulFertser> upgrdman: welcome :)
2014-03-22T07:28:56 < PaulFertser> 07:55 < GargantuaSauce> -lm might need to go at the very end of ldflags
2014-03-22T07:28:56 < PaulFertser> 07:56 < upgrdman> GargantuaSauce: still doesnt work :(
2014-03-22T07:29:08 < PaulFertser> Heh, it was at the end of ldflags I assume :)
2014-03-22T07:29:17 < PaulFertser> But ldflags were before the source files for some reason.
2014-03-22T07:29:24 < PaulFertser> That's what was unexpected.
2014-03-22T07:29:39 < upgrdman> well my makefile just has cflag, since i compile/link/etc all at once
2014-03-22T07:29:55 < upgrdman> suppose i can fix that now :)

2014-03-22T07:30:48 < GargantuaSauce> that is one of the worst gotchas of gcc i think
2014-03-22T07:31:03 < upgrdman> ya, i mean, why would that matter?
2014-03-22T07:31:10 < PaulFertser> GargantuaSauce: gcc is totally unrelated here
2014-03-22T07:31:36 < PaulFertser> GargantuaSauce: that's a gotcha of traditional Unix "ld" linker which for performance reasons is one-pass by default.
2014-03-22T07:31:48 < PaulFertser> But this behaviour can be altered easily.
2014-03-22T07:32:02 < upgrdman> should all of the -I, -L, -lfoo stuff be in LDFLAGS?
2014-03-22T07:32:12 < GargantuaSauce> not -I
2014-03-22T07:32:15 < GargantuaSauce> just -l -L
2014-03-22T07:32:44 < upgrdman> ok
2014-03-22T07:33:03 < PaulFertser> GargantuaSauce: you can have -Wl,-( before all your source/object files and -Wl,-) after and it'll just search everything repeatedly.
2014-03-22T07:33:04 < upgrdman> i wonder why this problem didnt crop up when linking stm's libs, which were also -l'd before my code
2014-03-22T07:33:56 < GargantuaSauce> huh ok
2014-03-22T07:34:44 < PaulFertser> upgrdman: probably -lstm32f0 has nothing useful and you get everything from f0lib/*.c ?
2014-03-22T07:35:26 < PaulFertser> upgrdman: -I are preprocessor directories, used before the compile stage, so can't be related to linking :)
2014-03-22T07:37:46 < upgrdman> PaulFertser: in this project yes, but in some earlier stuff i use stm's libs
2014-03-22T07:37:51 < upgrdman> weird. oh well.
2014-03-22T07:39:07 < PaulFertser> atan2f in an IRQ feels a bit fishy, but I assume you have the reason.
2014-03-22T07:41:51 < upgrdman> PaulFertser: its a balancing robot, using atan2f in the accelerometer isr. well testing it at least.
2014-03-22T07:42:20 < upgrdman> so far i have been getting away with atan ~= tan = y/x, if near zero... :)
2014-03-22T07:42:25 < GargantuaSauce> it's probably a good idea to just save the imu values in the interrupt and then do the computations in a loop in main()
2014-03-22T07:42:31 < GargantuaSauce> in sort of a producer-consumer arrangement

2014-03-22T07:42:41 < upgrdman> thought i would try the proper way, and see if a noticable benefit or less occurs
2014-03-22T07:42:44 < GargantuaSauce> otherwise you have to worry about irq priorities because the calc is slow as hell
2014-03-22T07:42:46 < PaulFertser> Well, if he decision needs to be made as urgent as possible, then yes.

2014-03-22T07:43:08 < PaulFertser> Because ISR handler blocks other irqs with lower priorities etc.
2014-03-22T07:43:30 < PaulFertser> It's usually assumed a handler is not taking any considerable time ever.
2014-03-22T07:43:35 < upgrdman> GargantuaSauce: that sounds good. i was worried that my isr's might be getting backed up, but i toggle a gpio in my isr's and probed... plenty of free time.
2014-03-22T07:43:55 < PaulFertser> But if he needs to do something based on the results of the calculation as soon as possible, then it might be the right way to do it.
2014-03-22T07:44:16 < GargantuaSauce> also generally with pid control you want super accurate timesteps, and relying on the sensor's data ready output for that might be a bad idea
2014-03-22T07:44:51 < upgrdman> i'll think about it. i knew it was bad to do much in an ISR but have been lucky so far. getting spoiled with 32bit 64MHz micros
2014-03-22T07:45:05 < GargantuaSauce> yeah it sure is nice having a stupid amount of computation to play with :)
2014-03-22T07:45:09 < GargantuaSauce> even moreso with m4f
2014-03-22T07:45:17 < upgrdman> ya
2014-03-22T07:45:28 < Thorn> also if you use floating point hardware you'll need to worry about saving fp registers in your handler
2014-03-22T07:45:43 < PaulFertser> Damn, indeed!
2014-03-22T07:46:13 < Thorn> I'm not sure if the compiler will do that
2014-03-22T07:46:14 < GargantuaSauce> whoops, have totally neglected that
2014-03-22T07:46:24 < upgrdman> GargantuaSauce: how else would i do updates? i can't change my outputs until i have the new inputs, no?
2014-03-22T07:46:25 < PaulFertser> f0 here so it doesn't matter for the particular case but still.
2014-03-22T07:46:48 < GargantuaSauce> upgrdman well if it's just a single sensor sure that works
2014-03-22T07:46:54 < GargantuaSauce> but what about 3 with different rates?
2014-03-22T07:47:38 < GargantuaSauce> all i'm saying is consider the current solution to be quick and dirty, i guess
2014-03-22T07:47:39 < PaulFertser> upgrdman: I think he also means that for the feedback control algorithms to work nicely you should make all measurements and adjustments as monotonic as reasonably possible.
2014-03-22T07:47:47 < GargantuaSauce> yeah
2014-03-22T07:48:03 < upgrdman> GargantuaSauce: i've musing a gyro at 190Hz and accel at 100Hz... ya :( i use the gyro to determine the angle, and the accel to crudely trim the angle's drift
2014-03-22T07:48:10 < GargantuaSauce> heheh
2014-03-22T07:48:36 < upgrdman> yes i know.... im a fucking n00b :)
2014-03-22T07:48:45 < GargantuaSauce> and yeah so you have an i2c transaction between the interrupt (which for the sake of argument we'll consider to be regulary timed) and your calculation and adjustment
2014-03-22T07:48:46 < upgrdman> first robot, first pid, first attempt at any sort of dsp-ish stuff
2014-03-22T07:49:10 < PaulFertser> GargantuaSauce: btw, have you tried reproducing that shitty shit without tainting the kernel? Or can do you have at least some traceback logged somewhere? I'd be curious to look.
2014-03-22T07:49:10 < GargantuaSauce> and there's zero guarantee i2c comms will take a particular amount of time...if the slave feels like slowing it down it can
2014-03-22T07:49:32 < GargantuaSauce> and i'm not much farther along in the controls development so don't consider my word to be expertise :)
2014-03-22T07:49:40 < GargantuaSauce> nope PaulFertser, i don't really want to try without nvidia drivers
2014-03-22T07:49:42 < upgrdman> ok
2014-03-22T07:50:12 < GargantuaSauce> i can show you all the oopses i guess
2014-03-22T07:50:16 < PaulFertser> GargantuaSauce: hm, should be reasonably easy to do your testing in cli mode or with a remote X server?
2014-03-22T07:50:24 < PaulFertser> GargantuaSauce: ok, please do, I wonder if it's something obvious.
2014-03-22T07:50:50 < upgrdman> GargantuaSauce: so the safer/better way is to use the isr's to get the raw data. and have a timer to use whatever data happens to have arrived at a ~perfect frequency?
2014-03-22T07:51:04 < GargantuaSauce> basically yes
2014-03-22T07:51:18 < GargantuaSauce> you might have to introduce a latency of one sample in order to get the timing right
2014-03-22T07:51:27 < upgrdman> ok. will keep in mind for my next project or code clean up :)
2014-03-22T07:51:33 < upgrdman> ya
2014-03-22T07:51:39 < GargantuaSauce> but i am under the impression that lead-lag compensation falls under the umbrella of pid control
2014-03-22T07:51:43 < GargantuaSauce> so that shouldn't be a huge issue
2014-03-22T07:52:52 < GargantuaSauce> PaulFertser: there's a couple where the initial oops did not trigger a halt and then there were 2-3 more in different modules :|
2014-03-22T07:53:37 < upgrdman> bbl. thanks for the help guys!
2014-03-22T07:54:54 < PaulFertser> GargantuaSauce: I'm not sure why but when developing a control loop for UPS providing constant by adjusting output voltage I had to deviate from classical PID: http://paste.debian.net/89001/ (atmega code)

2014-03-22T07:58:50 < PaulFertser> GargantuaSauce: couldn't get the integral part working non-destructively no matter what coefficents I used, it either was too slow or started oscillating, so I ramped the "I" coefficent up but made it not accumulate anything.

2014-03-22T08:00:19 < GargantuaSauce> i am pretty sure most implementations end up capping I
2014-03-22T08:00:45 < GargantuaSauce> i intend to experiment with using a nice 'flattening' function like atan or something for it at some point
2014-03-22T08:02:19 < PaulFertser> Wikipedia article didn't tell me I should cap "I" and I had other important things to do rather then study the theory properly or do modelling :/
2014-03-22T08:03:19 < GargantuaSauce> the theory never covers capping I
2014-03-22T08:03:19 < PaulFertser> My stupid university had a course on control theory but it was fucking useless.
2014-03-22T08:03:30 < GargantuaSauce> it's always an implementation hack
2014-03-22T08:04:07 < PaulFertser> But why?! WHY? (/me is used to trust theory and respect mathematicians) ;)
2014-03-22T08:04:39 < GargantuaSauce> hehe
2014-03-22T08:04:48 < GargantuaSauce> the models are nice until you try and apply them to reality
2014-03-22T08:05:31 < PaulFertser> Well, at least I now feel better knowing I'm not the only naughty boy here.

2014-03-22T08:37:20 < upgrdman> so earlier we were talking about linked. and ld does it in basically one pass. how can this be? can't one object file depend on things "later", and later things depend on "earlier" things?
2014-03-22T08:37:28 < upgrdman> *linkinh
2014-03-22T08:37:32 < upgrdman> linking even
2014-03-22T08:39:12 < jpa-> actually, later things cannot generally depend on earlier things
2014-03-22T08:39:32 < jpa-> and when earlier things depend on later things, the linker just keeps a list of stuff that is "still to be found"
2014-03-22T08:40:02 < upgrdman> hmm
2014-03-22T08:40:43 < PaulFertser> upgrdman: you can mention libs many times in the command line. Or use -( -) (grouping)
2014-03-22T08:40:45 < upgrdman> well if i "gcc *.c -o output" how can the linker order them? alphabetically certainly wouldnt do it
2014-03-22T08:41:36 < PaulFertser> It can't, *.c is expanded by shell.
2014-03-22T08:41:55 < upgrdman> yes
2014-03-22T08:41:57 < upgrdman> well
2014-03-22T08:42:22 < upgrdman> for example, if file1.c depends on some stuff in file2.c, could file2.c not also depend on stuff in file1.c?
2014-03-22T08:42:31 < dongs> "depends"?
2014-03-22T08:42:38 < jpa-> "import symbols from"

2014-03-22T08:58:13 < GargantuaSauce> when you compile multiple c files at once, they all end up in one object right
2014-03-22T08:59:17 < dongs> dohnt think so
2014-03-22T08:59:37 < GargantuaSauce> so their symbols are cross-referenced differently than the symbols in that resultant object and those in libraries linked with -l
2014-03-22T09:01:51 < GargantuaSauce> and in the linking process after each object is handled, all unused symbols are culled
2014-03-22T09:06:58 < GargantuaSauce> i think the distinction between .o compilation units and .a libraries comes into play here also but i am not familiar enough to elaborate
2014-03-22T09:07:12 < upgrdman> ya. im apparently way too tired. i was confusing the object-making process, and the lib linking process. i know better, but have been away far too long.

2014-03-22T09:39:03 < GargantuaSauce> maybe coocox doesnt have support for the former?
2014-03-22T09:39:04 < nine-tails> dongs: :(
2014-03-22T09:39:07 < hesperaux> GargantuaSauce, i had an inkling about that. :O
2014-03-22T09:39:16 < GargantuaSauce> afaik it is possible to flash v2 onto it
2014-03-22T09:39:37 < hesperaux> really? I guess there's no different in hardware really
2014-03-22T09:39:58 < nine-tails> no difference, just the names are different
2014-03-22T09:41:44 < PaulFertser> There's some difference
2014-03-22T09:42:50 < Abhishek_> is it possible to get the ST-LINK/V2-1 firmware on the Nucleo boards onto the ST-LINK/V2s on say, F4Disco?
2014-03-22T09:43:16 < dongs> if bootloader is same and they release firmware update for stdink
2014-03-22T09:43:20 < dongs> and you decrypt the userspace part
2014-03-22T09:43:26 < dongs> and then force to flash it on disco yeah
2014-03-22T09:43:29 < dongs> whats specail about it?
2014-03-22T09:43:33 < dongs> the massstorage shit?
2014-03-22T09:43:40 < hesperaux> i just got a nucleo
2014-03-22T09:43:46 < hesperaux> haven't messed with it yet
2014-03-22T09:43:54 < hesperaux> the VLdiscovery has UMS
2014-03-22T09:44:04 < hesperaux> i plugged it in and it brought up a 32MB flash drive
2014-03-22T09:44:22 < hesperaux> not sure where they hid all the 32MB
2014-03-22T09:44:32 < Abhishek_> it's a fake header
2014-03-22T09:44:38 < nine-tails> aka faker
2014-03-22T09:44:47 < hesperaux> ah, ok
2014-03-22T09:44:57 < hesperaux> it only has like 3KB of data on it right now
2014-03-22T09:46:23 < hesperaux> GargantuaSauce, apparently coocox lists support for this chip, as well as stlink and stlinkv2
2014-03-22T09:49:41 < nine-tails> hesperaux: openocd the fucker
2014-03-22T09:49:58 < PaulFertser> coocox doesn't use openocd
2014-03-22T09:50:05 < PaulFertser> If it used, stlinkv1 would work fine.
2014-03-22T09:52:46 < hesperaux> i tried updating the discovery firmware too, but it didn't help
2014-03-22T09:52:51 < hesperaux> it is at V1 btw
2014-03-22T09:54:30 < nine-tails> PaulFertser: as i said

2014-03-22T10:00:24 < hesperaux> it's configurable to do one of three things: SYSRESETREQ, HWRESET, VECTRESET
2014-03-22T10:00:31 < hesperaux> it's set to SYSRESETREQ. I tried all three though
2014-03-22T10:01:29 < zyp> SYSRESETREQ is usually what you want
2014-03-22T10:02:01 < zyp> and that doesn't really have anything to do with «connecting under reset»
2014-03-22T10:03:38 < upgrdman> what's vectreset? just change PC to 0x00?
2014-03-22T10:04:21 < zyp> reset cpu without resetting peripherals
2014-03-22T10:04:34 < hesperaux> i apologize. so then what determines if it is connecting under reset?
2014-03-22T10:04:54 < zyp> both SYSRESETREQ and VECTRESET are bits in one of the SCB registers
2014-03-22T10:05:12 < upgrdman> hesperaux: http://farrellf.com/temp/stlink.jpg
2014-03-22T10:05:32 < upgrdman> do you see a blue "connect under reset" line in yours?
2014-03-22T10:06:16 < hesperaux> yes, in the st-link utility
2014-03-22T10:06:21 < upgrdman> ok
2014-03-22T10:06:53 < upgrdman> then in your ide that isnt working, poke around for a feature like that. not just the type of reset, but whether it actually does it when attempting to connect
2014-03-22T10:07:05 < upgrdman> i've never use cocox so not sure how
2014-03-22T10:07:14 < hesperaux> k i'll have a look
2014-03-22T10:08:10 < hesperaux> cacherom is enabled. startup has "run to main" checked... semihosting is disabled. then all there is in debugger config is SWD vs. JTAG and the clock frequency

2014-03-22T10:45:00 < Thorn> I'm powering my board from a wall wart (9V 500mA). load 10mA -> all ok. load 150mA -> square wave from 3 to 12V
2014-03-22T10:46:21 < Thorn> the inductor (onboard buck) is buzzing pretty loudly and the buck outputs 4.2V instead of 5

2014-03-22T11:57:41 < dongs> cool
2014-03-22T12:03:18 < madist> anyone has used the PCF8574 butt expander ? From reading the datasheet it seems the INT pin should be normally high. But on the circuit I've assembled it is normally low and goes high on an interrupt generating event. I'm not sure if I'm reading the datasheet wrong or there's something else wrong. http://www.nxp.com/documents/data_sheet/PCF8574_PCF8574A.pdf
2014-03-22T12:03:42 < dongs> isnt this arduino pro territory
2014-03-22T12:03:46 < dongs> and intel galileo
2014-03-22T12:03:48 < madist> possibly
2014-03-22T12:04:08 < dongs> The active LOW open-drain interrupt output (INT) can be connected
2014-03-22T12:04:13 < dongs> its opendrain, did you pull it up
2014-03-22T12:04:23 < dongs> or else it has no idea what its doing
2014-03-22T12:04:23 < madist> I just wired an LED from it to +
2014-03-22T12:04:26 < dongs> lulzz
2014-03-22T12:04:32 < dongs> thats not how it wor ks
2014-03-22T12:04:44 < madist> so the LED should turn on when an interrupt fires.
2014-03-22T12:05:12 < madist> its not connected to the micro yet.
2014-03-22T12:06:23 < jpa-> sure that is how it works
2014-03-22T12:06:34 < jpa-> but is the led now normally ON or normally OFF?
2014-03-22T12:06:39 < madist> normally ON
2014-03-22T12:06:46 < madist> goes off if I toggle one of the inputs.
2014-03-22T12:07:14 < jpa-> any resistor in your circuit?
2014-03-22T12:07:27 < madist> just to limit the LED current
2014-03-22T12:07:34 < jpa-> in series with led, right?
2014-03-22T12:07:45 < madist> yes.

2014-03-22T17:43:55 < Thorn> why if you connect the K of the zener to the D instead of S the circuit will conduct with both +ve and -ve input voltage? http://www.ozqrp.com/graphics/rev_pol_mosfet_small.png
2014-03-22T17:44:57 < madist> there's something wrong with that mosfet symbol
2014-03-22T17:45:14 < jpa-> wouldn't the parasitic diode conduct anyway?
2014-03-22T17:45:27 < madist> the parasitic diode should be pointing the other way
2014-03-22T17:46:23 < jpa-> what is that circuit supposed to do anyway?
2014-03-22T17:46:48 < Thorn> my spice simulation shows thic circuit works as intended (unless you move the zener as I described)
2014-03-22T17:46:55 < Thorn> reverse polarity protection
2014-03-22T17:47:31 < jpa-> why 15V? what is the significance of the value?
2014-03-22T17:47:47 < Thorn> it's < than max Vgs of the mosfet
2014-03-22T17:47:51 < jpa-> ah, to protect the fet if the voltage is higher.. yeah
2014-03-22T17:47:56 < Thorn> right
2014-03-22T17:48:16 < Thorn> altthough I'm not sure it will protect the mosfet in the reverse polarity case
2014-03-22T17:48:28 < jpa-> it will, even better
2014-03-22T17:48:43 < jpa-> atleast when connected between G and S
2014-03-22T17:49:39 < gxti> indeed
2014-03-22T17:49:57 < jpa-> madist: ah, parasitic diode is correct way around but D vs. S is unconventional for high-side switch
2014-03-22T17:50:59 < madist> yeah he's doing weird things
2014-03-22T17:51:04 < jpa-> not really
2014-03-22T17:51:14 < madist> Thorn: can't you just put a diode across + and -
2014-03-22T17:51:25 < gxti> ...
2014-03-22T17:51:25 < madist> to short out the supply in the event of reverse polarity
2014-03-22T17:51:37 < madist> that's the proper way to do reverse polarity protection
2014-03-22T17:51:45 < Bird|otherbox> madist: wha?
2014-03-22T17:51:46 < Thorn> ok I see how the zener works in the reverse case, I drew my schematics wrong x_x
2014-03-22T17:52:12 < gxti> madist: i guess you're the circuit police now?
2014-03-22T17:52:14 < jpa-> Thorn: if the diode is on the other side, S will float higher through the load, but G will stay low due to forward conductance through zener to D => G lower than S => FET conducts
2014-03-22T17:52:35 < Bird|otherbox> btw: what I do in conjunction with the reverse-polarity FET is a bidirectional TVSS at the power entrance
2014-03-22T17:52:41 < jpa-> madist: only works for small powered and current limited suplies
2014-03-22T17:52:48 < Thorn> yeah I redrew my sch and it's all obvious lol. thanks
2014-03-22T17:52:50 < jpa-> madist: what if this is a >500W supply?
2014-03-22T17:53:02 < Thorn> xacto knife time
2014-03-22T17:53:21 < gxti> jpa-: blowing a fuse is sometimes good enough
2014-03-22T17:53:37 < jpa-> gxti: yes, but even that might not happen if you don't use a really big diode
2014-03-22T17:53:46 < Bird|otherbox> I'd rather it simply not turn on when confronted with reverse polarity
2014-03-22T17:53:59 < gxti> applications vary
2014-03-22T17:54:02 < madist> jpa-: the problem with this kind of mosfet switch is that its effectively sharing the reverse voltage with the circuit being protected and if the circuit being protected is a high impedance circuit (like a lot of cmos circuits) then the mosfet will do fuck all to protect the circuit
2014-03-22T17:54:04 < gxti> not everything needs to be completely idiot-proof
2014-03-22T17:54:06 < gxti> BUT
2014-03-22T17:54:12 < gxti> calling it 'the proper way' is stupid
2014-03-22T17:54:31 < jpa-> madist: how is it "sharing it"?
2014-03-22T17:54:47 < madist> jpa-: the mosfet and the circuit being protected form a voltage divider

2014-03-22T17:55:38 < madist> if circuit impedance == off resistance of the mosfet. the reverse voltage/2 across the circuit being protected.
2014-03-22T17:55:52 < jpa-> madist: sure, but a reverse biased FET is gigaohms.. and if your circuit has exposed CMOS pins, it will die by ESD soon enough anyway
2014-03-22T17:56:25 < Bird|otherbox> madist: you're mixing up input and power-supply impedances
2014-03-22T17:56:33 < madist> I don't know. Someone who understands these things much better than me told me that a reverse diode is the only sane way to protect a circuit.
2014-03-22T17:56:46 < jpa-> applications vary, like gxti said
2014-03-22T17:56:48 < Bird|otherbox> madist: he's a fool for saying that :P
2014-03-22T17:57:00 < jpa-> madist: cargo cult is a bad way to do things
2014-03-22T17:57:02 < madist> I'll take his word over yours.
2014-03-22T17:57:07 < gxti> we won't
2014-03-22T17:57:16 < gxti> if he really understood it he would have explained
2014-03-22T17:57:17 < jpa-> better understand the implications of each circuit
2014-03-22T17:57:20 < madist> Bird|otherbox: also, I'll assume that the many commercial circuits that use a diode know better than you.
2014-03-22T17:57:33 < Bird|otherbox> madist: does everyone in the commercial world use a shunt diode? O.O
2014-03-22T17:57:42 < jpa-> madist: or maybe the applications that use it have different requirements
2014-03-22T17:57:50 < jpa-> like, say, dirt cheap
2014-03-22T17:57:56 < madist> possibly

2014-03-22T17:58:43 < jpa-> but yeah, for low-power applications that do not usually get reverse input, a shunt diode is ok
2014-03-22T17:58:50 < Bird|otherbox> jpa-: also, a series diode is still useful for reverse polarity protection, especially if you have an unregulated supply
2014-03-22T17:59:14 < jpa-> yes, again a different kind of application :)
2014-03-22T17:59:28 < madist> jpa-: a diode guarantees that the circuit will never see more than 0.6 (or 0.3) volts in reverse. Your mosfet circuit makes no such guarantee.
2014-03-22T17:59:44 < jpa-> madist: unless you also have a guarantee of the load impedance
2014-03-22T18:00:21 < Bird|otherbox> madist: what did whoever-told-you-about-this say about the series diode approach?
2014-03-22T18:00:22 < gxti> you could add a reverse shunt after the mosfet
2014-03-22T18:00:40 < madist> Bird|otherbox: I'd rather not say. You might get offended.
2014-03-22T18:01:07 < Bird|otherbox> madist: err, just give me the gist of his opinion then :P
2014-03-22T18:01:13 < madist> A series diode protects nothing.
2014-03-22T18:01:43 < gxti> demonstrably false

2014-03-22T18:03:57 < madist> jpa-: I suspect the problem with the mosfet circuit is that there is a range of voltages where the mosfet is not fully off.

2014-03-22T21:00:06 < PaulFertser> I see, for simple devices that might be cheaper than stm32f072 + can phy.
2014-03-22T21:00:56 < Thorn> absolutely
2014-03-22T21:02:55 < PaulFertser> digikey unit price 3.12$ for lpc11c22, not exactly cheap.
2014-03-22T21:03:04 < PaulFertser> Well, ttyl, good luck with it! :)
2014-03-22T21:03:49 < jpa-> err... helping some guy set up a serial device.. "set the baudrate as 38400" "doesn't work" => screenshot of settings.. "you have baudrate set as 115200.. it must be 38400" "oh it has to be *exactly* 38400???"

2014-03-22T21:17:04 < jpa-> Thorn: uhhh.. is that a new cool way to blow up a FET?
2014-03-22T21:17:55 < qyx_> huh, overvoltage protection?
2014-03-22T21:18:01 < Thorn> I don't know what the point of that circuit is. you can use p6ke or something
2014-03-22T21:18:17 < Thorn> which is designed to dissipate some power
2014-03-22T21:18:32 < qyx_> single tvs will be probably enough
2014-03-22T21:18:39 < qyx_> or zener
2014-03-22T21:19:17 < jpa-> wouldn't that cause the FET to be partially conductive and heat up dramatically?
2014-03-22T21:20:13 < qyx_> probably, it would be in the linear region until the fuse blows

2014-03-22T21:38:20 < karlp> I've got a cp2102 usb-uart dongle attached to a uart on my f4 disco board, and sometimes when I reflash the board itself, or press the reset button, the serial dongle doesn't see any output again until I restart the terminal program,
2014-03-22T21:38:30 < karlp> what's that likely to be a problem with? it's not always,
2014-03-22T21:39:02 < karlp> when I restart the terminal program, it immediately gets data that would have been printed earlier too

2014-03-22T22:00:34 < Thorn> a zener or 2 zeners back to back in series
2014-03-22T22:00:51 < upgrdman> ok
2014-03-22T22:01:02 < GargantuaSauce> don't MOVs fall into that category also?
2014-03-22T22:01:28 < fbs> mov isnt a diode
2014-03-22T22:01:34 < gxti> i think TVS are physically structured to be able to absorb energy peaks
2014-03-22T22:01:42 < gxti> where a zener might fail
2014-03-22T22:01:59 < gxti> but electrically they're the same
2014-03-22T22:02:13 < GargantuaSauce> i am pretty sure TVS can refer to a tvs diode or a mov or even a spark gap
2014-03-22T22:02:14 < upgrdman> ok. that's what i thought
2014-03-22T22:02:35 < fbs> GargantuaSauce: yea tvs diode is a better name
2014-03-22T22:03:19 < upgrdman> aren't MOVs not so good for transients? don't they take a little time to heat up and conduct?
2014-03-22T22:03:52 < GargantuaSauce> yeah they are slower than diodes for sure
2014-03-22T22:04:15 < GargantuaSauce> but can take way more total energy
2014-03-22T22:04:20 < upgrdman> yes
2014-03-22T22:04:31 < fbs> isnt it common to ues both?
2014-03-22T22:04:53 < BrainDamage> TVS generally work in avalanche region
2014-03-22T22:05:04 < BrainDamage> zeners instead work trough tunnel
2014-03-22T22:05:46 < gxti> diodes marketed as 'zener diodes' over 7 volts also work through avalanche mechanism, it's not really an important distinction for a designer :p
2014-03-22T22:06:25 < BrainDamage> it is important if you really care about he I-V characteristic
2014-03-22T22:06:30 < BrainDamage> but most of the time you don't
2014-03-22T22:06:30 < gxti> fbs: well, it's quite common for cheap stuff to just have MOV
2014-03-22T22:06:39 < gxti> fbs: but if you go all out then yeah you can have MOV + diode + spark gap
2014-03-22T22:06:47 < upgrdman> so avalanche / tunnel is strictly a device design/construction issue right? the end user would never notice one way or the other?
2014-03-22T22:06:49 < karlp> if a usb class spec says, "blah blah, on this error case, device must halt the endpoint" is that the same as what gsmcmullin's/libopencm3s usb library calls "stall the endpoint" ?
2014-03-22T22:06:59 < BrainDamage> you can notice if you plot I-v
2014-03-22T22:07:05 < upgrdman> o
2014-03-22T22:07:15 < BrainDamage> but from an "high level" design, you generally don' care
2014-03-22T22:07:19 < karlp> yeah, ok, seems to be.
2014-03-22T22:07:28 < upgrdman> is one a steeper curve?
2014-03-22T22:07:45 < BrainDamage> yes, and the knee around the trigger point is rather different
2014-03-22T22:08:04 < BrainDamage> also, tunnel is way less dependent from temp
2014-03-22T22:08:43 < BrainDamage> but then again, you could just watch the plot and ignore the fabbrication detail
2014-03-22T22:08:59 < gxti> you'd have to check the plots anyway :P

2014-03-22T22:09:38 < BrainDamage> one part where it really matters
2014-03-22T22:09:41 < gxti> tunnel and avalanche have opposite sign tempcos, so at that crossover point of 7ish volts where both effects are present the tempco is near zero. that's why expensive voltage references often have that value.
2014-03-22T22:09:42 < BrainDamage> is if you abuse them :p

2014-03-22T22:10:39 < BrainDamage> knowing the mechanism there gives you hints of the internal structure so you can pick the best approximate one
2014-03-22T22:10:47 < BrainDamage> but it's not exactly a common use case ...
2014-03-22T22:14:40 < qyx_> i saw some schematics of VCOs with diodes as varicaps
2014-03-22T22:16:12 < BrainDamage> you can even use a mosfet to create a varactor, best if the bulk pin is wired
2014-03-22T22:21:05 < Thorn> why is my buck inductor voltage amplitude 21V even though input is about 13V
2014-03-22T22:22:13 < BrainDamage> is that peaks or contigous?
2014-03-22T22:22:34 < BrainDamage> the delay time while the mos is off and the diode is on will make the inductor get a voltage spike
2014-03-22T22:24:27 < gxti> Thorn: 21V where exactly?
2014-03-22T22:26:29 < Thorn> it's a ~13V square wave with overshoots on both edges which add up to 2*5V to the amplitude
2014-03-22T22:27:34 < gxti> sounds sort of like you're probing it wrong

2014-03-23T07:05:34 < dongs> nice
2014-03-23T07:14:23 < dongs> mostly GNU assembler
2014-03-23T07:14:26 < dongs> useles for any real work
2014-03-23T07:15:59 < PaulFertser> dongs: you can't convert it to keil's assembler? Just translate with gas and then disasm with your keil tool and that's it.
2014-03-23T07:16:40 < PaulFertser> avrs manage to do usb with just 12MHz quartz, but here they need 24MHz :)

2014-03-23T17:04:05 < fbs> they wat
2014-03-23T17:04:31 < dongs> so like
2014-03-23T17:04:40 < dongs> because im too lazy to figure out how to add DFU descriptors
2014-03-23T17:04:44 < dongs> into my userspace app
2014-03-23T17:04:51 < dongs> i'm just disconnecting usb and rebooting to bootloader
2014-03-23T17:05:03 < dongs> good idea y/n/m
2014-03-23T17:05:16 < fbs> depends on what its doing

2014-03-23T17:09:43 < dongs> hm, i did value handover using  bkp registers before in dfu and cant find it
2014-03-23T17:09:51 < dongs> i hate rewriting same shit
2014-03-23T17:10:05 < dongs> <zyp> I'd use my favorite OS search function to find this in less than 10 seconds
2014-03-23T17:10:38 < chris_99> are there any usb device examples for the stm32f429, i just downloaded the STM32Cube_FW_F4_V1.1.0, package, but can only find a usb host example

2014-03-23T17:24:35 < Devilholk> I'm working with EXTI interrupts on a stm32f100 and every pin but one works. I can't get it to use PD0, this one is OSCIN but I have remapped it and it works when I poll the port input register so the pin works
2014-03-23T17:24:52 < Devilholk> Is there something special about EXTI interrupts on remapped pins?

2014-03-23T18:13:00 < trepidaciousMBR> Yup, I've never measured it, but I think you can see up to kHz in the right conditions - e.g. a small bright light with a low duty cycle at night - like stupid tail lights :)
2014-03-23T18:13:20 < trepidaciousMBR> You can also see flicker better in peripheral vision

2014-03-23T18:49:34 < dongs> annd when it breaks, it kills swd and everything

2014-03-23T23:04:04 < Thorn> ok wtf. I have 2 types of smd leds that have the same marking (a T on the bottom and 2 dots on the top, corresponding to the bottom on the T), but on one of them the dots are on the A side, on the other one the dots ase on the K side
2014-03-23T23:05:00 < Thorn> is there a standard or anything
2014-03-23T23:06:32 < Thorn> on the plus side I now have two fully working boards
2014-03-23T23:08:33 < Steffanx> i guess the standard is there is no standard?
2014-03-23T23:08:52 < Steffanx> you're not the first one to run into that issue.
2014-03-23T23:10:40 < nine-tails> yep.. first time i hear this
2014-03-23T23:12:21 < Steffanx> not the first time for me :P
2014-03-23T23:17:51 < qyx_> i heard this in the past and also have multiple led types with a/k reversed

2014-03-23T23:27:13 < Fleck> Reference manual says: "The default clock of the STM32F4xx MCUs is the internal RC oscillator."  Where are the default RCC configs set in stdperiphlib? As clock source after .bin upload is PLL, and I did not change it in my code...
2014-03-23T23:29:44 < Thorn> startup code calls SystemInit() or something like that
2014-03-23T23:29:54 < Thorn> before main()
2014-03-23T23:29:55 < Fleck> ohh, let me check!

2014-03-23T23:32:06 < Fleck> SystemInit() calls SetSysClock()...

2014-03-24T04:37:06 < upgrdman> ya that happens
2014-03-24T04:37:17 < upgrdman> JST-XH is one of the more common balance connectors
2014-03-24T04:37:27 < upgrdman> but some brands dont give a shit and use whatever they like
2014-03-24T04:37:55 < upgrdman> http://www.tjinguytech.com/charging-how-tos/balance-connectors
2014-03-24T04:38:00 < upgrdman> just need an adapter
2014-03-24T04:38:14 < upgrdman> typically just connector is different. sometimes the wiring order too.
2014-03-24T04:40:25 < upgrdman> iirc hyperion uses one of the less common connectors
2014-03-24T04:40:31 < hesperaux_> has anyone here used 400KHz I2C?

2014-03-24T05:19:28 < englishman> or this which is pretty much copypasted i guess http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0553a/BABGHFIB.html

2014-03-24T05:31:53 < dongs> and you have to use -f suffix functions and make sure all your constants are defined with 0.0f 1.0f tytpe  thing
2014-03-24T05:32:10 < dongs> and check your .map file for any double-related conversions and there's a gcc -Wdouble-promotion or something warning

2014-03-24T05:52:33 < upgrdman> would a double be full-software, or would they be assisted by the hw float stuff?
2014-03-24T05:53:40 < Bird|otherbox> it'd have to be full software
2014-03-24T05:53:41 < dongs> unsure. my guess would be no
2014-03-24T05:53:44 < dongs> yeah
2014-03-24T05:54:04 < Bird|otherbox> you could do a single-extended using paired singles

2014-03-24T16:44:06 < Thorn> why is your top of stack = 2002ffff
2014-03-24T16:44:33 < Thorn> should be last address + 1 = 20030000 iirc
2014-03-24T16:44:58 < Thorn> but this shouldn't matter because last 2 bits of sp are hardwired to 0 anyway iirc

2014-03-25T13:21:17 < jpa-> (and hand-soldered.. maybe it is a kit that has to be soldered by user? :P
2014-03-25T13:28:13 < PaulFertser> Without silk too, but yes, plated vias certainly mean it's not toner transfer... still very strange.

2014-03-25T16:16:09 < Steffanx> only when you're watching the weird kinds of pron scrts_w ...
2014-03-25T16:21:14 < madist> Since when did pee porn come under the 'weird' category ?
2014-03-25T16:22:18 < SlaveToTheSauce> anything aside from interfacing with the standard orifices is in the weird category
2014-03-25T16:23:09 < madist> so anything other than anal/oral/aural/nasal is weird for you ??
2014-03-25T16:23:55 < SlaveToTheSauce> i didn't say for me
2014-03-25T16:24:23 < madist> So I've done something weird.
2014-03-25T16:24:30 < madist> I've got two different bits of hardware on the same port. One is a display and one is an i2c device.
2014-03-25T16:24:39 < SlaveToTheSauce> kinky
2014-03-25T16:25:05 < madist> and now I can't think of a clean way to do the #defines to allow both devices to be used simultaneously.
2014-03-25T16:25:26 < SlaveToTheSauce> the answer is templates
2014-03-25T16:25:36 < madist> the answer is always templates.
2014-03-25T16:25:46 < Steffanx> My standard is the only one that could, so yes: weird
2014-03-25T16:25:46 < madist> unfortunately the C compiler doesn't support templates yet.
2014-03-25T16:26:00 < madist> got any suggestions / example code I can look at ?
2014-03-25T16:26:42 < SlaveToTheSauce> are you implying that a vague suggestion of a single language feature is not enough information to produce a neat and working implementation?
2014-03-25T16:26:53 < madist> of course not.
2014-03-25T16:27:00 < SlaveToTheSauce> good, you had me worried there
2014-03-25T16:27:04 < madist> far be it for me to suggest something so outlandish.

2014-03-25T16:28:08 < madist> I guess a separate bitmask for the bits/port pins used by each device ?
2014-03-25T16:29:02 < madist> i find myself struggling with things that should be very easy
2014-03-25T16:29:13 < SlaveToTheSauce> does the code really need to be generalized enough that you could plunk it down on any board with arbitrary peripherals chosen for your devices?
2014-03-25T16:29:20 < SlaveToTheSauce> when in doubt, hardcode
2014-03-25T16:29:38 < zyp> madist, what do you mean by simultaneously?
2014-03-25T16:29:41 < SlaveToTheSauce> fix it later if need be
2014-03-25T16:29:42 < jpa-> generalizing from one example etc., yeah, justkeep it simple
2014-03-25T16:29:43 < madist> does excessive masturbation turn the brain to pudding ?
2014-03-25T16:30:03 < SlaveToTheSauce> if it's the mental masturbation derived from excessive abstraction, yes
2014-03-25T16:30:27 < madist> zyp: I think I'm overthinking things. I'm just worried that a function to set bits for the display might fuck up the I2C communication.
2014-03-25T16:30:34 < SlaveToTheSauce> i used to wank all over my implementations to generalize them but then i realized for everything i do it takes 10% as long to just change the hardcoded values on the rare occasion i need to change it
2014-03-25T16:30:55 < zyp> madist, but what do you mean by simultaneously?
2014-03-25T16:31:27 < madist> reading from the i2c device and writing to the display ?
2014-03-25T16:31:44 < jpa-> i guess he is worried about race conditions when initializing the port modes
2014-03-25T16:31:46 < madist> that isn't really a problem is it ?
2014-03-25T16:31:52 < madist> Its my first time doing this.
2014-03-25T16:32:12 < zyp> ah, same port, not same pins
2014-03-25T16:32:19 < SlaveToTheSauce> not a problem
2014-03-25T16:32:20 < madist> yeah, I think I'll just code it up a bit and see if there really is a problem or I'm imagining things.
2014-03-25T16:32:40 < zyp> I thought you were talking about multiplexing shit on the same pins, and I couldn't understand how you'd get that to work
2014-03-25T16:32:57 < madist> I can do that. my display has a latch.
2014-03-25T16:33:06 < madist> but I'm not going to be so ambitious yet.
2014-03-25T16:33:10 < zyp> sure, but your i2c device doesn't :p
2014-03-25T16:33:31 < madist> it should have an enable pin. I think.
2014-03-25T16:33:41  * madist scrambles for the datasheet.
2014-03-25T16:33:49 < Rickta59> buttons and output only can share a pin
2014-03-25T16:34:22 < zyp> having different functions on various pins within one port shouldn't be a problem at all

2014-03-25T19:11:59 < emeb> lots of pools, lots of block walls, lots of idiot drivers.
2014-03-25T19:12:08 < Laurenceb__> number plate is too good to be true
2014-03-25T19:12:23 < emeb> we've had drivers plow through our wall and end up in our back yard twice.
2014-03-25T19:12:30 < emeb> both times teenage girls.
2014-03-25T19:13:05 < emeb> don't get the significance of the license plate tho
2014-03-25T19:14:13 < qyx_> at least here you have to be 18+
2014-03-25T19:15:23 < emeb> yeah - combination of immature brains, distraction, and driving = hilarity and death

2014-03-25T19:16:20 < qyx_> and many adults don't get their license that early
2014-03-25T19:16:30 < qyx_> mostly they wait and get it during university
2014-03-25T19:17:06 < emeb> actually it's more common for USians to not drive these days than it used to be
2014-03-25T19:17:34 < emeb> lots of "millenials" are waiting until later due to cost / public transit / etc.
2014-03-25T19:17:35 < qyx_> same here, roads are getting saturated
2014-03-25T19:17:43 < qyx_> it is better to use bus/train

2014-03-25T19:42:49 < gnomad> that's saying a lot.
2014-03-25T19:43:02 < emeb> moving sidewalks can take you anywhere you need to go.
2014-03-25T19:43:08 < gxti> the biggest US cities have decent public transport, but the rest are very spread-out and driving oriented
2014-03-25T19:43:24 < gnomad> Only a select few US cities have anything remotely close to good public transit.

2014-03-25T20:57:43 < Steffanx> zyp: i was bored, so i tried to run laks on a L1. So far so good, but in one of your commits you removed rcc_init in the startup code, where did you plan to move it to?
2014-03-25T21:04:41 < zyp> call it from main
2014-03-25T21:05:43 < zyp> I removed it from startup code because in the bootloader I wrote, I needed to not call it until after I decided to run in bootloader mode
2014-03-25T21:05:47 < zyp> ref. http://cgit.jvnv.net/arcin/tree/bootloader.cpp#n277
2014-03-25T21:06:35 < Steffanx> oh ok, so nothing fancy in mind :)
2014-03-25T21:06:56 < Steffanx> *you had nothing fancy in mind
2014-03-25T21:07:50 < zyp> well, ideally I should make something better than «assume HSI is hooked to an 8MHz crystal and switch to PLL at max speed»

2014-03-25T21:12:27 < zyp> Steffanx, problems tend to be easier to solve when they are a prerequisite for what you want to do than when they are imaginary ;)
2014-03-25T21:12:30 < SlaveToTheSauce> especially with flux residue on there!
2014-03-25T21:13:51 < Steffanx> Sure zyp, but this is so basic. Just some RTC, comparator and ADC stuff.
2014-03-25T21:13:55 < Steffanx> and spi
2014-03-25T21:16:34 < zyp> hmm, and you said L1?
2014-03-25T21:17:14 < zyp> that's going to require some work if you want it to run at something different than what it boots at
2014-03-25T21:17:31 < zyp> since RCC and flash interface is different
2014-03-25T21:18:27 < Steffanx> Yes, true. Isn't the RCC pretty similar, except for the extra registers about what to do in the low(er) power modes
2014-03-25T21:18:38 < zyp> possibly
2014-03-25T21:18:51 < zyp> but you need to set flash wait states before clocking up, I guess
2014-03-25T21:19:15 < zyp> anyway, patches appreciated if you do it
2014-03-25T21:23:18 < Steffanx> it first had to run without hardfaulting. That was the first step :)
2014-03-25T21:27:10 < gnomad> PCBs without a soldermask were quite common on US-made consumer gear for as long as consumer-gear was actually made in the US

2014-03-26T02:35:42 < dongs> hah 2 billion
2014-03-26T02:35:43 < dongs> hilarious
2014-03-26T02:35:53 < dongs> zuckerberg must have a need to write off some profits
2014-03-26T02:39:14 < bvsh> i wonder what were his reasons to buy it
2014-03-26T02:39:18 < bvsh> it's all opensource..
2014-03-26T02:39:34  * bvsh thinks oculus is awesome
2014-03-26T02:39:38 < bvsh> but i'd take 2B :)
2014-03-26T02:41:14 < gnomad> I think Facebook might have jumped the shark with that one.

2014-03-26T02:43:40 < chris_99> i'm kind of confused what FB wants to do with it, make a 3d version of FB?
2014-03-26T02:44:32 < bvsh> they prolly will just end up killing the thing
2014-03-26T02:45:16 < gnomad> My guess is they are trying to diversify before they become the next myspace.
2014-03-26T02:45:32 < chris_99> mmm
2014-03-26T02:46:01 < gnomad> of course, they could have developed something like occulus rift for a lot less than $2B
2014-03-26T02:46:27 < bvsh> they didn't really have to
2014-03-26T02:46:31 < bvsh> it's all there..
2014-03-26T02:46:35 < bvsh> available..
2014-03-26T02:46:58 < chris_99> theres one which uses something similar to DLP which looks kind of interesting too, but i don't think the FoV is as great as the Rift
2014-03-26T02:47:14 < gnomad> like I said, I think FB has jumped the shark...

2014-03-26T10:10:16 < dongs> As we did ourselves. We spend days, months and lost nights to came up to this idea and to this small board, just for you guys to enjoy it and take it further into your own projects. You have the board, you have the software online, from now on its down to you to learn more about it, search the internet, everywere if you need to do something with it, we can help with guiding you into the right direction, we can not do everything for you.

2014-03-26T10:36:38 < hesperaux> the other day i put a 144pin STM32F407ZGT6 on one of those adapter boards
2014-03-26T10:36:43 < hesperaux> i got it to program :D
2014-03-26T10:36:53 < hesperaux> so not much difference, except that doesn't have a connector
2014-03-26T10:37:03 < hesperaux> but still, their thing is very small and could be used by students
2014-03-26T10:37:10 < hesperaux> i don't see it being a highly useful product

2014-03-26T10:46:52 < hesperaux> was recently doing a board layout
2014-03-26T10:47:10 < hesperaux> i wondered if it was a horrible thing to do to have multiple vias for one signal path (to route around shit)
2014-03-26T10:47:19 < hesperaux> these were analog channels or 10mbit spi channels
2014-03-26T10:48:30 < dongs> depends on signal/situation really. could be bad could be doesn't matter. 10mbit is not a lot.
2014-03-26T10:48:41 < madist> dongs: the rc controller boards shop is a full time job ?
2014-03-26T10:48:53 < dongs> madist: no just hobby
2014-03-26T10:49:05 < madist> oh you have a separate day job ?
2014-03-26T10:49:07 < dongs> (thats taking up way too much fuckign time
2014-03-26T10:49:24 < hesperaux> the signals are from op in-amps at 0-3.3V
2014-03-26T10:49:53 < hesperaux> when i'm doing the actual layout, everything seems enormous and vias seem cumbersome, even though if I stand back I realize they are all .5mm parts and very small vias
2014-03-26T10:50:12 < hesperaux> i guess the other question would be: for analog voltages as I mentioned, what sort of trace width is acceptable?
2014-03-26T10:50:26 < dongs> heh. i also have proper spec pcb manufacturing so my vias on normal projects are 10/20mil
2014-03-26T10:50:30 < hesperaux> so far i've just been using about the same width as the pin...cuz the pads are only so wide anyway

2014-03-26T11:26:02 < dongs> The digital filter used in the PonoPlayer has minimal phase, and no unnatural (digital sounding) pre-ringing. All sounds made (including music) always have reflections and/or echoes after the initial sound. There is no sound in nature that has any echo or reflection before the sound, which is what conventional linear-phase digital filters do. This is one reason that digital sound has a reputation for sounding "unnatural" and harsh.
2014-03-26T11:26:23 < dongs> All circuitry is zero-feedback. Feedback can only correct an error after it has occurred, which means that it can never correct for all errors. By using proprietary ultra-linear circuitry with wide bandwidth and low output impedance, there is no need for unnatural sounding feedback.
2014-03-26T11:26:37 < dongs> he output buffer used to drive the headphones is fully discrete so that all individual parameters and circuit values and parts quality can be fully optimized for the absolute finest sound quality. The output impedance is very low so that the PonoPlayer delivers perfectly flat frequency response and wide volume range using virtually any set of headphones.

2014-03-26T16:26:58 < aadamson> I guess, but then that would be 16mhz 32 bit, so you'd need 16 to make 72mhz, 32 bit parallel

2014-03-26T17:46:45 < Thorn> I'm not sure about for per-m^2 savings for (relatively) large runs
2014-03-26T17:46:52 < Thorn> in my experience (prototype orders) russian fabs always charge extra setup costs for solder mask though
2014-03-26T17:49:35 < Thorn> looking http://rezonit.ru/price/ the savings (solder mask on 2 sides vs. none) can be from $30 to $60 per m^2

2014-03-26T18:03:46 < ohto_porola> I watched his videos from 30c3, they're not all bad,
2014-03-26T18:03:54 < ohto_porola> but, not my background to judge :)
2014-03-26T18:04:00 < zyp> ohto_porola, you're gonna keep that nick?
2014-03-26T18:04:03 < ohto_porola> he's been working on it for a few years
2014-03-26T18:04:10 < ohto_porola> nah, i'll get bored of it soon enough :)
2014-03-26T18:05:31 < zyp> emeb, so in other words it's pretty uninteresting?
2014-03-26T18:05:57 < emeb> zyp: well, my warning bells went off as soon as they said "Arduino of FPGAs"
2014-03-26T18:06:18 < zippe> Why would you do that when you can get a Papilio?
2014-03-26T18:06:30 < emeb> which basically means "We've hidden all the hard stuff so n00bs don't get confused"
2014-03-26T18:06:46 < emeb> and is code for "Don't expect to do anything particularly complex"
2014-03-26T18:07:10 < ohto_porola> the boards do look really boring, but I didn't get that feeling form carsten's talks, that pshdl was dumbing it down and taking away stuff
2014-03-26T18:07:24 < emeb> zippe: exactly - there are already hundreds of inexpensive FPGA boards available
2014-03-26T18:07:52 < Thorn> but those require you to use verilog or vhdl which is HARD!
2014-03-26T18:08:19 < emeb> learning _any_ new language that's marginally useful is hard
2014-03-26T18:08:21 < BrainDamage> I only wish the toolchains were a bit better
2014-03-26T18:08:35 < BrainDamage> esp the batch processing part
2014-03-26T18:09:16 < emeb> I'd been using Verilog for 20 yrs before I tried VHDL and that was a pain.
2014-03-26T18:10:36 < emeb> reading through the PSHDL docs - seems like his solution is to put the whole toolchain on his own servers
2014-03-26T18:11:00 < emeb> so you need to use his "cloud" based approach to synthesize.
2014-03-26T18:12:00 < emeb> Because Verilog / VHDL are the only entry points for FPGA design he likely has to convert PSHDL to one of those, then go through a normal toolchain and then spew the bitstream back to you.
2014-03-26T18:12:59 < Thorn> how is he going to pay for the servers?
2014-03-26T18:13:21 < Thorn> charge subscription fees?
2014-03-26T18:13:29 < PaulFertser> That might actually be useful if you can't run all those sick proprietary tools yourself. But why not just allow Verilog sources?
2014-03-26T18:14:50 < PaulFertser> "Its similarity to C makes it very readable and writeable" How can a language that needs to _describe_ hardware be similar to C? C is imperative.
2014-03-26T18:15:17 < emeb> yeah. and how is the inherent parallelism handled? Haven't gotten to that part yet.
2014-03-26T18:15:27 < zyp> PaulFertser, similar in syntax?
2014-03-26T18:15:35 < zyp> braces instead of begin/end keywords, etc…

2014-03-26T18:18:02 < PaulFertser> zyp: that's not what really makes languages similar, it's about the same as comparing IDEs by their syntax highlight colourscheme or something.
2014-03-26T18:18:16 < PaulFertser> So it can't help learn that new language anyhow.
2014-03-26T18:18:25 < zyp> it's not?
2014-03-26T18:18:42 < emeb> ugh - in PSHDL the clock is implied.
2014-03-26T18:18:58 < emeb> wonder how you handle designs with multiple clocks...
2014-03-26T18:18:59 < zyp> PaulFertser, I'd argue that python is pretty different from C-like languages, for instance
2014-03-26T18:19:42 < zyp> emeb, have you seen any of the python-based HDL fronts?
2014-03-26T18:19:59 < emeb> zyp: I've only glanced over them.
2014-03-26T18:20:24 < zyp> anything that looks useful?
2014-03-26T18:20:50 < emeb> zyp: not really, but that's likely a personal bias based on my pre-existing experience.
2014-03-26T18:21:06 < zyp> I suspect the same
2014-03-26T18:21:43 < zyp> even though I like python, I'm not confident it's very useful to use for generating HDL
2014-03-26T18:21:53 < zyp> you probably run into shortcomings as often as advantages
2014-03-26T18:24:17 < PaulFertser> zyp: programming in python differs a lot from programming in C not because python uses indentation to compose blocks but rather because of dynamic typing, garbage collection, powerful standard library etc etc.
2014-03-26T18:25:42 < ds2> thought verilog IS like C?
2014-03-26T18:27:01 < zyp> PaulFertser, but I were referring to the syntax, not the typing
2014-03-26T18:27:18 < PaulFertser> Aren't hdls closer to macro languages than to imperative programming languages anyway?
2014-03-26T18:28:13  * emeb doesn't know enough language theory to answer that.
2014-03-26T18:28:39 < emeb> dunno the difference between macro, imperative, functional, etc.
2014-03-26T18:29:01 < zyp> me neither, I don't care what languages are classified as, I care how they are in use :p

2014-03-26T18:31:26 < PaulFertser> emeb: imperative is about "do this, then do that, then do this in a loop until something etc". Functional is "here's how to compute x from y, here's how to compute z knowing a and b, etc". Macro (as I understand it) is about: "here's how to generate code for purpose A based on parameters X and Y".
2014-03-26T18:32:16 < emeb> PaulFertser: then in that case I'd hazard that HDLs are more like functional languages.
2014-03-26T18:32:18 < PaulFertser> So in HDL you're like "generate me this, this and that, and connect them such and such".
2014-03-26T18:33:37 < PaulFertser> Typical macro language differs from functional languages because macros don't really check types, they just "expand" the arguments.
2014-03-26T18:34:44 < emeb> VHDL certainly checks types - to the point of being annoying. :)
2014-03-26T18:35:17 < emeb> Verilog isn't so type-tastic, but that's mainly because it has very limited types.
2014-03-26T18:38:13 < emeb> Looking through the explanations on http://pshdl.org/ I'm not seeing the screaming advantages.
2014-03-26T18:38:42 < emeb> It kind of seems like the big objection he's got to VHDL is that it's so complex and verbose. That's a given.
2014-03-26T18:39:11 < emeb> So he's created a frontend for it that limits the types and compresses the syntax.
2014-03-26T18:39:32 < emeb> and at the same time looks a bit like C++.
2014-03-26T18:41:29 < PaulFertser> Hm, some fancy way to do FPGAs with control over layout, promising many speed and space advantages: http://raintown.org/lava/
2014-03-26T18:42:32 < zyp> systemverilog seems like a nice improvement over verilog
2014-03-26T18:42:37 < zyp> with interfaces and stuff
2014-03-26T18:42:51 < zyp> shame it's not supported by the common tools
2014-03-26T18:42:53 < emeb> I know a lot of guys who use it. I've seen it but never used it.
2014-03-26T18:45:54 < emeb> PaulFertser: interesting stuff on Lava there.
2014-03-26T18:46:25 < emeb> I can recall back in the 90's when I was pushing the old Xilinx parts as fast as they could go that we would have loved that.
2014-03-26T18:46:48 < emeb> we had to do a lot of hand place / route back then because the PAR tools sucked.
2014-03-26T18:46:57 < emeb> Lately though things are pretty good.

2014-03-27T03:51:16 < dongs> https://www.kickstarter.com/projects/1419380698/connect-your-hd-camcorder-to-your-raspberry-pi :???
2014-03-27T03:52:37 < englishman> Why it is not possibly to feed HDMI video into the Raspberry Pi?
2014-03-27T03:53:07 < dongs> Has Anyone Really Been Far Even as Decided to Use Even Go Want to do Look More Like?
2014-03-27T03:53:20 < gxti> yes, last thursday.
2014-03-27T03:53:57 < englishman> hm but the guy seems to know stuff
2014-03-27T03:54:57 < dongs> nto really.
2014-03-27T03:55:01 < dongs> I was part of a project that used MG3500
2014-03-27T03:55:04 < dongs> its complete garbage
2014-03-27T03:55:14 < dongs> therefore anything that uses it in 2014 is also complete garbage
2014-03-27T03:55:36 < gxti> i can't really tell what he means either
2014-03-27T03:55:48 < englishman> but it has stm32
2014-03-27T03:55:54 < dongs> no it doesnt
2014-03-27T03:55:57 < gxti> but you would think that "it doesn't work at all and this is impossible" is something you would find in the prototyping phase
2014-03-27T03:56:00 < englishman> yes
2014-03-27T03:56:05 < englishman> STM32F051 ARM Cortex M0
2014-03-27T03:56:31 < englishman> where does it show mg3500?
2014-03-27T03:56:52 < zyp> I'm still waiting for f072
2014-03-27T03:57:05 < dongs> englishman: some other shit he's pushing as plan B
2014-03-27T03:57:07 < dongs> H264 encoder stuff
2014-03-27T03:57:23 < dongs> huh what hte fuck he has a HDMI transmitter on there
2014-03-27T03:57:32 < dongs> why the hell.
2014-03-27T03:58:08 < dongs> The HDMI in and HDMI out chip are configured via the I2C bus. It turned out however, that the HDMI in chip requires a special I2C protocol which the I2C library of the Raspberry Pi can not support. The I2C command only allows to read and write up to 32 bytes from a single I2C address. The HDMI In chip however requires that 256 bytes are written, to initialize the 256 byte EDID memory, which is an integral part of the HDMI in chip. As a quick workaround the I2C bus 
2014-03-27T03:58:32 < zyp> haha
2014-03-27T03:58:35 < GargantuaSauce_> dongs do you have a h264 codec you recommend, then?
2014-03-27T03:58:56 < englishman> pop open the lid on DJI Lightbridge and check out what they use
2014-03-27T03:59:08 < gxti> just plop down a cortex-a69 and install GNU/LINUX and use x264
2014-03-27T03:59:19 < englishman> or use raspberri pi
2014-03-27T03:59:59 < dongs> http://www.ti.com/lit/ds/slls881f/slls881f.pdf doesnt look hard
2014-03-27T04:00:02 < dongs> i wonder which part he failed with?
2014-03-27T04:00:10 < GargantuaSauce_> software encoding is certainly an option, but i also want to compare it to an asic that doesn't suck
2014-03-27T04:00:27 < gxti> the part he failed with is asking for funds before demonstrating that shit works at all
2014-03-27T04:00:33 < dongs> oh thats SD shit
2014-03-27T04:00:43 < englishman> nice motorazr on first page
2014-03-27T04:00:44 < dongs> gxti: what, thats how you roll on dickstarter
2014-03-27T04:00:56 < gxti> which is why it's so much fail
2014-03-27T04:00:59 < englishman> all you need is an altium render
2014-03-27T04:01:02 < dongs> in other news, paypal'd https://developer.nvidia.com/jetson-tk1
2014-03-27T04:01:26 < gxti> i could ask the obvious question but i won't
2014-03-27T04:01:35 < englishman> hes becoming a buttcoin miner
2014-03-27T04:01:56 < zyp> dongs, I kinda want one, but I'd rather wait for the Cortex-A57 variant
2014-03-27T04:02:06 < GargantuaSauce_> i've only worked with tegra-2 and it's garbage
2014-03-27T04:02:18 < zyp> (and I have no idea what to use it for, like always)
2014-03-27T04:02:18 < dongs> zyp: A15 is g ood enough
2014-03-27T04:02:34 < GargantuaSauce_> can't decode hd video
2014-03-27T04:02:36 < dongs> < englishman> hes becoming a buttcoin miner
2014-03-27T04:02:38 < dongs> busted
2014-03-27T04:02:40 < zyp> depends on the purpose
2014-03-27T04:02:41 < dongs> :(
2014-03-27T04:02:54 < dongs> actually my plan was to do doge.
2014-03-27T04:02:57 < zyp> probably good enough for sitting on a shelf and collecting dust
2014-03-27T04:03:01 < englishman> dogecoin digging
2014-03-27T04:03:30 < zyp> http://www.phytec.com/products/single-board-computers/ <- I just got one of these, still need to figure out what to do with it
2014-03-27T04:03:45 < gxti> i would buy one but i'd just end up putting it in the corner with the other lunix-capable boards i don't use
2014-03-27T04:04:05 < dongs> zyp, the problem with that shit is freescale
2014-03-27T04:04:37 < zyp> I haven't developed an opinion about freescale yet, how do they suck?
2014-03-27T04:04:46 < dongs> they just do
2014-03-27T04:04:51 < dongs> i.MX?? = suck
2014-03-27T04:04:52 < gxti> dongs hates it, must be ok
2014-03-27T04:05:26 < zyp> well, I dunno
2014-03-27T04:05:47 < dongs> fuck I need to assemble shit but lazy
2014-03-27T04:05:54 < dongs> maybe not bother for today.
2014-03-27T04:06:04 < zyp> the a5+m4 combination seems interesting, and it seems pretty well documented
2014-03-27T04:06:21 < zyp> not sure what I'd use it for though
2014-03-27T04:06:37 < dongs> lunix
2014-03-27T04:06:44 < zyp> maybe quadrotor shit, run realtime stabilization on m4 and navigation on lunix
2014-03-27T04:06:51 < gxti> glue it to the tegra board

2014-03-27T20:49:52 < gnomad> The best you are going to find is an introduction to one of the many libraries or RTOSs for them.

2014-03-27T20:56:17 < gnomad> newlib is a pig for smaller MCUs.
2014-03-27T20:56:43 < akaWolf> Steffanx: realview i.e.?
2014-03-27T20:56:58 < Steffanx> newlib-nano isn't that bad gnomad, but that is not newlib
2014-03-27T20:57:50 < akaWolf> Steffanx: it's project smaller, than GAE, then it's simpler to studing of gcc-based toolchains..
2014-03-27T20:59:35 < Steffanx> I'm not sure what you mean, akaWolf
2014-03-27T20:59:50 < gnomad> what is the state of newlib-nano?
2014-03-27T21:00:03 < Steffanx> "it works"  is a good state?
2014-03-27T21:00:18 < akaWolf> Steffanx: if you mean RealView, when say "armcc", than there are two major reasons: it's close-sourced, and it's requires a money for using

2014-03-28T02:33:44 < qyx_> uh oh
2014-03-28T02:34:12 < GargantuaSauce_> beautiful
2014-03-28T02:34:26 < qyx_> hesperaux: which mcu?
2014-03-28T02:34:34 < hesperaux> that's an STM32F4
2014-03-28T02:34:47 < qyx_> try to change gpio output do 25MHz
2014-03-28T02:34:50 < hesperaux> i've tried with a variety of clock options. that pic is 16Mhz internal RC with 160MHz systemclock
2014-03-28T02:34:52 < qyx_> if you have it at 100
2014-03-28T02:35:01 < hesperaux> qyx_, i have it at 50, but that's a though
2014-03-28T02:35:05 < hesperaux> thought*
2014-03-28T02:35:16 < qyx_> hm, now long is that sck line?
2014-03-28T02:35:18 < qyx_> how
2014-03-28T02:35:42 < hesperaux> the sck line is approx 14 inches ;), but i'm measuring it in the middle
2014-03-28T02:35:56 < hesperaux> it is jumpered into a breadboard, then jumpered out to the SPI device
2014-03-28T02:36:04 < GargantuaSauce_> maybe it just needs to be terminated with a resistor
2014-03-28T02:36:15 < GargantuaSauce_> oh breadboard lol
2014-03-28T02:36:16 < qyx_> 14 inches is quite long
2014-03-28T02:36:21 < qyx_> hh
2014-03-28T02:36:44 < hesperaux> yeah but it's only 10Mhz
2014-03-28T02:36:48 < hesperaux> but there is the breadboard aspect
2014-03-28T02:36:57 < qyx_> 10MHz is quite much for a breadboard
2014-03-28T02:37:05 < GargantuaSauce_> i've indeed succeeded at pushing 25MHz or something through a breadboard but yeah it's not easy to get working
2014-03-28T02:37:14 < GargantuaSauce_> especially not with long leads like that
2014-03-28T02:37:19 < hesperaux> xD
2014-03-28T02:37:20 < hesperaux> so amazin
2014-03-28T02:37:48 < GargantuaSauce_> termination may still be worth trying
2014-03-28T02:39:18 < hesperaux> i'm gonna probe the pin directly with nothing attached first
2014-03-28T02:39:22 < hesperaux> if it looks clean, i'll do what you suggest
2014-03-28T02:39:29 < GargantuaSauce_> but obviously the best solution is to run the jumper directly to the device with no breadboard in the middle
2014-03-28T02:40:26 < qyx_> and definitely try shorter wires if you can

2014-03-28T04:25:42 < dongs>  i doubt opensores implementation of it can be compared to ms-rdp
2014-03-28T04:25:45 < gxti> better test it against vnc then because yeah
2014-03-28T04:25:49 < gxti> they probably both suck
2014-03-28T04:25:52 < dongs> it probably sucks just as bad if not worse than vnc
2014-03-28T04:26:16 < gxti> and with vnc you can use x11vnc to start a server on an existing session, i don't think you can do that with the lunix rdp servers. only starts new sessions.
2014-03-28T04:26:39 < upgrdman> well ya, but sometimes the only box i have access is just windows, and no admin so cant install software.

2014-03-28T04:30:56 < gnomad> I've not found them any different than ms clients
2014-03-28T04:30:57 < hesperaux> if you wanna use the pi remotely with a gui
2014-03-28T04:31:00 < hesperaux> you could use nxclient
2014-03-28T04:31:05 < hesperaux> works very well in general
2014-03-28T04:31:11 < hesperaux> or you could use X forwarding over SSH

2014-03-28T04:31:17 < hesperaux> nah
2014-03-28T04:31:24 < hesperaux> how is it a pain?
2014-03-28T04:31:50 < qyx_> x forwarding works ok for me
2014-03-28T04:31:54 < qyx_> comparable to rdp
2014-03-28T04:32:17 < qyx_> vnc is much worse as it works totally differently
2014-03-28T04:32:17 < hesperaux> i use X forwarding for lots of stuff - it works surprisingly well
2014-03-28T04:32:22 < hesperaux> vnc is awful
2014-03-28T04:33:02 < gnomad> that's because X forwarding has been around for 25+ years now
2014-03-28T04:33:20 < gnomad> and 25 years ago 10 Mbps ethernet was fast...
2014-03-28T04:34:16 < hesperaux> ;D
2014-03-28T04:34:41 < gxti> 10Mbps is much faster than 100KB/s, which is what our scenario entails.
2014-03-28T04:34:52 < qyx_> only 10x
2014-03-28T04:35:23 < qyx_> but it should work if you are not going to run firefox over it
2014-03-28T04:35:29 < qyx_> or similar weird graphical stuff
2014-03-28T04:35:31 < gxti> anyway i think the obvious answer is rdp because you don't even need to download anything.
2014-03-28T04:36:12 < hesperaux> speaking of 10mbit: http://postimg.org/image/xd4kvsprf/
2014-03-28T04:36:25 < hesperaux> 18" of wire for single-ended 10Mhz square comes out looking like that :D
2014-03-28T04:36:36 < upgrdman> pretty square wave
2014-03-28T04:36:45 < qyx_> better than the one before
2014-03-28T04:37:14 < hesperaux> the one before had a breadboard between the two 6" jumpers
2014-03-28T04:37:18 < upgrdman> that remind me of when i probe circuits and just rely on mains earth ground as my ground.
2014-03-28T04:37:21 < hesperaux> right now that's 1 6" jumper from GND to probe
2014-03-28T04:37:32 < hesperaux> and then 6" + 6" jumper from CLK to probe
2014-03-28T04:37:38 < upgrdman> because, you know, ground clips or springs require too much effort ;)
2014-03-28T04:37:43 < hesperaux> upgrdman, heh
2014-03-28T04:38:06 < qyx_> uhm
2014-03-28T04:38:22 < qyx_> scope -> computer -> usb -> debugger -> board -> scope
2014-03-28T04:38:57 < hesperaux> huh?
2014-03-28T04:39:12 < hesperaux> the scope is grounded to the board through a 6" jumper
2014-03-28T04:39:37 < upgrdman> hesperaux: i also like the signal integrety of this i2c line i probed:  http://farrellf.com/temp/open-drain-pull-up.png
2014-03-28T04:39:38 < qyx_> that was what upgrdman said
2014-03-28T04:39:45 < hesperaux> oh, yeah
2014-03-28T04:39:47 < upgrdman> ya
2014-03-28T04:39:50 < hesperaux> huge ground loop
2014-03-28T04:40:00 < hesperaux> dude give me your scope upgrdman ok?
2014-03-28T04:40:11 < upgrdman> although i usually power my device with my lab psu, so a slightly shorter ground loop :)
2014-03-28T04:40:33 < hesperaux> upgrdman, which line is the i2c?
2014-03-28T04:40:34 < hesperaux> the yellow?
2014-03-28T04:40:35 < upgrdman> hesperaux: :) i still have my ds1102. need ot ebay that old dog

2014-03-28T04:40:48 < upgrdman> hesperaux: ya
2014-03-28T04:40:50 < hesperaux> i want a scope with a better ADC
2014-03-28T04:40:55 < hesperaux> the 1052E has a pretty lame one
2014-03-28T04:41:01 < hesperaux> upgrdman, wow a triangle lol
2014-03-28T04:41:11 < hesperaux> but you are trying to do 550K on a 400K max protocol
2014-03-28T04:41:16 < hesperaux> or was that SMBus?
2014-03-28T04:41:26 < upgrdman> actually its cause i was uber lazy when i made my board
2014-03-28T04:41:33 < qyx_> you can run i2c at whatever speed you want
2014-03-28T04:41:39 < GargantuaSauce_> you can squeeze a megabit or something out of i2c if you're a masochist
2014-03-28T04:41:40 < qyx_> using internal pullups?
2014-03-28T04:41:41 < upgrdman> no external pull up. and stm32 has a weak internal pull up
2014-03-28T04:41:49 < hesperaux> wat
2014-03-28T04:41:53 < hesperaux> seriously?
2014-03-28T04:41:57 < upgrdman> srsly
2014-03-28T04:42:26 < upgrdman> hesperaux: it actually works fined if you dont probe it :) but add the parasitic cap of a probe/scope, and it looks fugly
2014-03-28T04:42:37 < hesperaux> interesting
2014-03-28T04:43:08 < gxti> uncertainty principle applied to electronics
2014-03-28T04:43:28 < gxti> you can observe the signal with an oscope or you can observe the circuit working but not both :P
2014-03-28T04:43:33 < hesperaux> yep
2014-03-28T04:43:47 < upgrdman> its was the first thing i probed that made use of my pretty UltraVision / digital phosphore / wtf they call it, so i saved it
2014-03-28T04:44:00 < hesperaux> upgrdman, which scope is that, and also does it do protocol decode and packet triggering?
2014-03-28T04:44:24 < upgrdman> ds4014. iirc it has lots of decoding/triggering, but i tend to do they with a log anal'er
2014-03-28T04:44:35 < hesperaux> k
2014-03-28T04:44:47 < hesperaux> no LA on that one? i see it's a DS not an MSO
2014-03-28T04:45:07 < upgrdman> not on mine
2014-03-28T04:45:13 < upgrdman> and didnt feel like paying for one
2014-03-28T04:45:20 < hesperaux> gotcha
2014-03-28T04:45:41 < upgrdman> my $50 owls is smaller and convenient

2014-03-28T11:17:42 < kuldeepdhaka> maybe this can explain http://pastebin.com/Ma76hWXc
2014-03-28T11:18:23 < jpa-> looks a lot like cortex-m3 libgcc
2014-03-28T11:18:31 < jpa-> what are your LDFLAGS?
2014-03-28T11:18:34 < jpa-> ah
2014-03-28T11:18:37 < jpa-> they are there

2014-03-28T11:18:54 < Thorn> I had that, bad ld params
2014-03-28T11:19:00 < jpa-> add -mcpu=cortex-m0 -mfloat... to LDFLAGS also
2014-03-28T11:19:03 < dongs> this is why i use a real compiler

2014-03-28T12:47:49 < jpa-> hmm.. UPM will not build a biofuel plant in finland because it would be too profitable

2014-03-28T15:07:22 < kuldeepdhaka> now, i get the problem in my head. im trying to use gcc as frontend to ld and gcc is passing incorrect lib path to ld. i did the same directly passing path and it worked.
2014-03-28T15:07:47 < kuldeepdhaka> passing path to ld
2014-03-28T15:09:03 < Thorn> you need to pass correct -m* parameters to gcc so it can select the correct library
2014-03-28T15:09:51 < kuldeepdhaka> how can i prevent gcc from passing non-thumb path to ld.   (i tried -mcpu=cortex-m0 -mfloat-abi=soft -mlittle-endian -mthumb -march=armv6-m -mno-thumb-interwork) still the same

2014-03-28T15:13:59 < karlp> do not, under any circumstances, do -Lsome/path/inside/your/gcc/install
2014-03-28T15:14:26 < jpa-> hey, I have done that also! :)  (but i agree, it is wrong :)
2014-03-28T15:14:48 < karlp> if you know how to do it, you're allowed to, but you're not allowed to ask for help with multilib arm vs thumb problems if you have done so :)
2014-03-28T15:15:14 < karlp> kuldeepdhaka: or, as was suggested before: rm Makefile

2014-03-29T05:01:24 < gnomad> the last PC I built was my fileserver and that was 4 years ago
2014-03-29T05:01:40 < dongs> i fucking hate that all makers use 100tqfp failmega2560, so the bga parts are impsosible to get
2014-03-29T05:02:23 < dongs> not to mention that its 18 fucking bucks
2014-03-29T05:02:34 < gnomad> whaa?

2014-03-29T05:03:01 < dongs> digikey doesnt even have  full trays stock
2014-03-29T05:03:39 < dongs> oh hm
2014-03-29T05:03:42 < dongs> they have 2.5k
2014-03-29T05:03:50 < dongs> but yeah still 18bucks.
2014-03-29T05:04:29 < gnomad> sometimes octoparts price tracking makes no sense..  http://octopart.com/detail/history?sid=66679141603
2014-03-29T05:05:09 < gnomad> but they were about $13 not too long ago, no?
2014-03-29T05:05:36 < dongs> wow nice
2014-03-29T05:07:12 < dongs> well
2014-03-29T05:07:17 < dongs> im just  g oing by single qty pricing at digikey
2014-03-29T05:07:18 < dongs> thing is,
2014-03-29T05:07:28 < dongs> 16-au (tqfp100 is 5 bucks in tray qtys
2014-03-29T05:07:32 < dongs> but 16-cu bga isn'
2014-03-29T05:07:35 < dongs> t even available
2014-03-29T05:07:40 < dongs> so im guessing its gonna be at least double that
2014-03-29T05:07:54 < dongs> to go through verical or vyrian or similar scamplace
2014-03-29T05:08:08 < gnomad> I never have been able to figure out just what qty octopart does their price graphs at...

2014-03-29T05:39:47 < dongs> i blame englishman
2014-03-29T05:40:26 < madist> will you be nice and modify his order ?
2014-03-29T05:41:10  * madist doesn't know how online carts work
2014-03-29T05:41:17 < madist> his CC is already charged  ?
2014-03-29T05:43:05 < englishman> its set to default
2014-03-29T05:43:11 < englishman> also, yes, i blame canada also
2014-03-29T05:46:37 < upgrdman> damn. why are some mcu's $20+ when you can buy a tablet-level SoC for around that price?
2014-03-29T05:47:28 < GargantuaSauce_> you can buy a tablet soc for half that
2014-03-29T05:47:41 < upgrdman> ok, ya
2014-03-29T05:47:55 < upgrdman> so why the seemingly overprice mcu's
2014-03-29T05:49:19 < GargantuaSauce_> i think there are pretty significant cost cutting measures in more 'modern' core architectures for one
2014-03-29T05:49:47 < upgrdman> ?
2014-03-29T05:50:04 < GargantuaSauce_> especially with superscalar stuff.  you pattern pipelines, alus, cache memory, etc notably above the specifications on the label
2014-03-29T05:50:16 < dongs> well, atmega2560 does NOT cost $18
2014-03-29T05:50:22 < dongs> its ancient as hell
2014-03-29T05:50:31 < GargantuaSauce_> and then disabling some components gives you room for the fab to have not-awesome yields
2014-03-29T05:50:33 < dongs> 8bit, 16mhz, 8k ram, 256k flash.
2014-03-29T05:50:39 < upgrdman> dongs: ya im not look at atmel. like some of the new f4's are fucking expensive
2014-03-29T05:50:49 < dongs> upgrdman: um, not so much.
2014-03-29T05:50:58 < GargantuaSauce_> whereas in an mcu you can't do that to the same degree I think
2014-03-29T05:51:00 < dongs> upgrdman: if you start buying them in trays / mass production they are cheap
2014-03-29T05:51:08 < dongs> just like you can't buy a tablet SoC for $5/ea
2014-03-29T05:51:18 < upgrdman> ya
2014-03-29T05:51:20 < dongs> but if you are chinese and make 100k of them, then its possible
2014-03-29T05:52:32 < upgrdman> http://www.mouser.com/ProductDetail/STMicroelectronics/STM32F417IGT6/?qs=sGAEpiMZZMv%2fbGM7XKYHKzdjpvKSSVD2
2014-03-29T05:52:45 < upgrdman> even if qty=1000, there're what, ~12$ each?
2014-03-29T05:54:10 < GargantuaSauce_> i am pretty sure mouser is not where you go when you want cheap
2014-03-29T05:54:21 < upgrdman> ya i know
2014-03-29T05:55:27 < dongs> I suspect tray price is something around 8 or so
2014-03-29T05:55:30 < dongs> on that one
2014-03-29T05:55:36 < upgrdman> hmmm ok
2014-03-29T05:55:46 < upgrdman> tray = how many?
2014-03-29T05:56:01 < dongs> depends on size. 100-250 or wahtever.
2014-03-29T05:56:22 < upgrdman> where can you buy trays for around that price? direct from stm?
2014-03-29T05:57:51 < dongs> maybe waveshare or so
2014-03-29T05:58:04 < dongs> IG is fucking HUGE tho
2014-03-29T05:58:28 < GargantuaSauce_> waveshare has the 407IG for $9.9/100
2014-03-29T05:58:36 < GargantuaSauce_> and yes, huge
2014-03-29T05:58:41 < upgrdman> ya i know :) was just making a point, since a tablet SoC, or even a fucking dingleberry pi SoC is miles ahead
2014-03-29T05:58:47 < GargantuaSauce_> packaging cost is pretty significant when there's a fuckton of pins
2014-03-29T05:58:54 < dongs> dingleberrypi SoC has no TRM
2014-03-29T05:59:05 < dongs> so its useless for someone who actually wants to do something with it
2014-03-29T05:59:10 < upgrdman> trm?
2014-03-29T05:59:19 < dongs> like RM0090
2014-03-29T05:59:31 < upgrdman> o. well ya, nda's.
2014-03-29T05:59:39 < upgrdman> agreed, that sucks
2014-03-29T06:00:06 < upgrdman> are there any tablet-ish SoCs with free docs?

2014-03-29T06:00:53 < upgrdman> are there any tablet-ish SoCs with free well-written docs?

2014-03-29T06:01:18 < GargantuaSauce_> now you're just being unreasonable

2014-03-29T06:01:52 < upgrdman> does ti do SoCs like that with free docs?
2014-03-29T06:01:58 < upgrdman> ti docs are nice

2014-03-29T06:02:31 < dongs> i think they start at $50/chip
2014-03-29T06:02:33 < dongs> if not more
2014-03-29T06:02:36 < upgrdman> o ok

2014-03-29T06:29:45 < dongs>  ???????????????????
2014-03-29T06:29:50 < hesperaux> anyone of you guys used external interrupts on an STM32F100 or similar?
2014-03-29T06:30:00 < dongs> ive used them on F103
2014-03-29T06:30:08 < hesperaux> dongs, this way it only charges when you already need it charged?
2014-03-29T06:30:26 < hesperaux> dongs, i've checked everything like 5 times...it won't interrupt on change
2014-03-29T06:30:43 < hesperaux> i'm using PC0 to trigger on rising edge for EXTI0
2014-03-29T06:30:52 < dongs> exti line enabled? gpio enabled and set as input? interrupt enabled? you're clearing that interrupt bit in handler?
2014-03-29T06:30:54 < hesperaux> i set the GPIO pinsource and portsource for the EXTI
2014-03-29T06:31:01 < hesperaux> GPIO is set as IN_FLOATING
2014-03-29T06:31:20 < hesperaux> i clear the bit in the handler; double checked that the handler is overriding the weak definition
2014-03-29T06:32:07 < hesperaux> i enabled the IRQ with the NVIC
2014-03-29T06:32:07 < dongs> AFIO clk is on?
2014-03-29T06:32:13 < dongs>   RCC_APB2PeriphClockCmd(RCC_APB2Periph_AFIO, ENABLE);
2014-03-29T06:32:16 < hesperaux> dongs, that's not a definite thing
2014-03-29T06:32:19 < hesperaux> hmm
2014-03-29T06:32:26 < hesperaux> i didn't realize i needed a clock for edge triggering
2014-03-29T06:32:35 < hesperaux> that was probably a dumb assumption
2014-03-29T06:32:37 < dongs> afio is for gpio routing or something
2014-03-29T06:32:40  * hesperaux checks for a clock
2014-03-29T06:32:42 < upgrdman> clock needed for everything except the clock controller :)
2014-03-29T06:32:54 < dongs> which is the shit that routes exti to stuff.
2014-03-29T06:33:15 < dongs> is GPIOC clock on too while youre at it
2014-03-29T06:33:15 < hesperaux> hmmm
2014-03-29T06:33:19 < hesperaux> i bet that's my problem!
2014-03-29T06:33:22  * hesperaux checks
2014-03-29T06:33:36 < hesperaux> GPIOC clock is enabled, yes
2014-03-29T06:33:42 < hesperaux> using that for multiple things so it was already on
2014-03-29T06:33:49 < hesperaux> but the AFIO is not hooked up to APB2
2014-03-29T06:33:52 < hesperaux> :O
2014-03-29T06:34:15 < dongs> i thought all of F1 series had same peripherals?
2014-03-29T06:34:39 < dongs> i mean if its on APB2 on F103 then it should be tehre on F100 too
2014-03-29T06:35:10 < hesperaux> you misunderstand me
2014-03-29T06:35:16 < hesperaux> i meant that I had not enabled it
2014-03-29T06:35:17 < dongs> o. you mean you didnt have it enabled
2014-03-29T06:35:18 < dongs> right.
2014-03-29T06:35:19 < hesperaux> so it wasn't attached in my config
2014-03-29T06:35:23 < hesperaux> yeah
2014-03-29T06:36:50 < hesperaux> i just enabled the AFIO clock
2014-03-29T06:36:54 < hesperaux> no luck yet
2014-03-29T06:37:13 < hesperaux> pin is set to IN_FLOATING, I know a square wave is  present on the pin and is referenced to the same ground
2014-03-29T06:37:24 < hesperaux> the GPIO speed is 10MHz
2014-03-29T06:37:30 < dongs> that doesnt matter
2014-03-29T06:37:33 < hesperaux> figured it didn't
2014-03-29T06:37:37 < hesperaux> wasn't sure though
2014-03-29T06:37:37 < dongs> speed is only for output
2014-03-29T06:37:42 < hesperaux> ok
2014-03-29T06:37:49 < hesperaux> just on a side note: how does it change the speed per pin..?
2014-03-29T06:37:50 < GargantuaSauce_> eh, attach debugger and examine all relevant config registers
2014-03-29T06:37:57 < dongs> ^
2014-03-29T06:38:00 < GargantuaSauce_> that changes the drive current
2014-03-29T06:38:03 < dongs> speed = ^
2014-03-29T06:38:04 < dongs> yeah that
2014-03-29T06:38:33 < GargantuaSauce_> or impedance i guess would be the more correct term
2014-03-29T06:38:37 < hesperaux> so
2014-03-29T06:38:45 < hesperaux> with a APB2 clock of 20M
2014-03-29T06:39:28 < hesperaux> if I set the GPIO speed to 10M, the rise time is equivalent to a 10M signal?
2014-03-29T06:39:55 < GargantuaSauce_> the bus clock is irrelevant to that
2014-03-29T06:40:08 < hesperaux> seems strange to me
2014-03-29T06:40:18 < GargantuaSauce_> and the rise time of course depends on what's in the circuit
2014-03-29T06:42:15 < hesperaux> ah, well yeah that would make sense
2014-03-29T06:43:19 < GargantuaSauce_> the setting is for the output impedance for driving a "typical" input circuit at the given frequncy i guess
2014-03-29T06:43:32 < hesperaux> okay that makes sense too
2014-03-29T06:43:46 < hesperaux> hmm
2014-03-29T06:43:49 < GargantuaSauce_> there's an iota of bullshit involved and in any case it's totally irrelevant to your input
2014-03-29T06:44:02 < hesperaux> ok
2014-03-29T06:45:20 -!- johntramp [~john@122-57-213-205.jetstream.xtra.co.nz] has joined ##stm32
2014-03-29T06:45:29 < GargantuaSauce_> another quick acid test would be to check the gpio's IDR, the result of that will basically bisect the issue into either the input itself or the interrupt triggering
2014-03-29T06:45:56 < hesperaux> so given that the input pin is set as IN_FLOATING, and initialized, that its port has an RCC clock enabled for GPIO and for AFIO, that the pinsource and portsource for that exti line are enabled, and that the EXTI is turned on and the NVIC IRQ is enabled for that EXTI...what else could it be?
2014-03-29T06:46:23 < hesperaux> GargantuaSauce_, okay, before or after the input signal is apparent?
2014-03-29T06:46:32 < upgrdman> while
2014-03-29T06:46:39 < GargantuaSauce_> well hold it high and check if the bit in idr is 1
2014-03-29T06:46:44 < hesperaux> k
2014-03-29T06:46:49 < GargantuaSauce_> and again, verify that all those things you're claiming are actually the case by looking at their config registers in the debugger
2014-03-29T06:47:10 < GargantuaSauce_> if you missed any of the relevant clock enables, the config register will be all zeros
2014-03-29T06:47:45 < hesperaux> is there a particular order that I need to enable each component of this?
2014-03-29T06:47:54 < hesperaux> i.e. GPIO, then RCC, then EXTI, then NVIC?
2014-03-29T06:48:16 < upgrdman> enable clock for periph before trying to set periph registers :)
2014-03-29T06:48:22 < GargantuaSauce_> the last one i fucked up doing exti stuff was missing  RCC_APB2ENR_SYSCFGEN , not sure if the f1 uses the same deal
2014-03-29T06:48:43 < dongs> i think syscfg is f4
2014-03-29T06:48:47 < GargantuaSauce_> yeah ok
2014-03-29T06:50:01 < hesperaux> enabling the RCC clocks is the first thing I do
2014-03-29T06:50:23 < hesperaux> then i init the GPIO, then EXTI/NVIC
2014-03-29T06:50:35 < hesperaux> btw, I'm trying to use two preemption levels. the first level is an ADC dma IRQ
2014-03-29T06:50:46 < hesperaux> that interrupt was working fine
2014-03-29T06:55:12 < hesperaux> debugging now
2014-03-29T06:59:49 < hesperaux> GPIOC's IDR = 0b1111110011011100
2014-03-29T07:00:08 < hesperaux> i'm interested in PC0
2014-03-29T07:00:20 < hesperaux> the pin is set to VDD right now

2014-03-29T07:02:48 < hesperaux> seems like it
2014-03-29T07:03:22 < hesperaux> i don't understand why - it is configured as IN_FLOATING
2014-03-29T07:03:32 < hesperaux> gotta look up which register sets that

2014-03-29T07:15:06 < hesperaux> according to the CRL register, PC0 is set as analog input...
2014-03-29T07:15:24 < hesperaux> grr, wrong port
2014-03-29T07:16:26 < hesperaux> i was mistaken before. the pin is changing state according to the input
2014-03-29T07:16:40 < hesperaux> it's set to floating input and is at logic 1 right now
2014-03-29T07:17:00 < hesperaux> when i switch the pin to gnd, it changes to 0
2014-03-29T07:17:04 < hesperaux> so input is working
2014-03-29T07:22:15 < GargantuaSauce_> okay so now check the rcc and exti and nvic registers

2014-03-29T07:26:20 < hesperaux> reading about how to do that now
2014-03-29T07:26:47 < GargantuaSauce_> there's a handy list at the end of each section in the reference manual
2014-03-29T07:29:55 < hesperaux> yeah, looking at that
2014-03-29T07:32:34 < hesperaux> ok, line 0 is not masked, the rising edge trigger is enabled and the falling edge trigger is disabled, as expected
2014-03-29T07:33:01 < hesperaux> what else is there?
2014-03-29T07:34:29 < GargantuaSauce_> nothing that comes to mind
2014-03-29T07:34:44 < GargantuaSauce_> uhh disable that other interrupt to make sure it isnt always preempting the exti one or something
2014-03-29T07:34:47 < GargantuaSauce_> past that i dunno
2014-03-29T07:35:01 < hesperaux> it can't be preempting it because it cannot occur unless this one occurs
2014-03-29T07:35:07 < hesperaux> the other one  happens if the adc finishes a conversion set
2014-03-29T07:35:19 < hesperaux> i don't start any conversions until the EXTI is triggered
2014-03-29T07:35:27 < hesperaux> the EXTI routine is what triggers the ADC conversion
2014-03-29T07:38:14 < hesperaux> oh FFS
2014-03-29T07:38:16 < hesperaux> it's working.
2014-03-29T07:38:33 < hesperaux> i changed the routine to do nothing but clear the bit so when i looked before, after enabling the AFIO clock, I didn't realize it was working
2014-03-29T07:38:38 < hesperaux> i'm a derp
2014-03-29T07:38:47 < hesperaux> i'm happy about this though
2014-03-29T07:38:50 < GargantuaSauce_> that shit is so easy to do with embedded stuff i find
2014-03-29T07:39:10 < GargantuaSauce_> i almost never do it in any development on the pc, web or native
2014-03-29T07:39:33 < hesperaux> i'd agree with that statement

2014-03-29T07:59:01 < hesperaux> is it as bad as their libraries?
2014-03-29T08:01:59 < hesperaux> is the following understanding correct? I have two interrupts. My NVIC is configured to use 2 bits for preemption priority. The first interrupt is at priority 1 and the second interrupt is at priority 2. The second interrupt occurs first, but takes a long time. Because the first interrupt has a lower preemption number, when that interrupt occurs, execution will move into its handler and then return to the second interrupt handler. Is that correct?

2014-03-29T12:00:19 < dongs> yeah
2014-03-29T12:01:20 < Claude> had similar effects too once , turned out i had a bad pcb lib . some elements (a pad) in the lib were some meters away from the center
2014-03-29T12:02:01 < dongs> nah its my own lib, its clean. shit is just broken. restarting it "fixes" it
2014-03-29T12:02:11 < Claude> ouch okay
2014-03-29T12:02:11 < dongs> once it drew a shitload of random placed gnd wires all over
2014-03-29T12:02:15 < dongs> hit end -> fixed
2014-03-29T12:10:07 < dongs> shit just leaving traces around regardless of doing move or drag is so damn annoying
2014-03-29T12:10:17 < dongs> i dont really care if it fucks them all up but it should at least leave them connected

2014-03-29T12:34:01 < dongs> Claude: how can i drag something without traces disconnecting>??? in pcb. emd -> disconnects. emm -> disconnects
2014-03-29T12:34:35 < Claude> press ctrl and drag?
2014-03-29T12:34:48 < dongs> nope
2014-03-29T12:34:55 < Claude> don't know if you mean that
2014-03-29T12:35:01 < dongs> ctrl has no effect
2014-03-29T12:35:24 < Claude> on the net?
2014-03-29T12:35:39 < Claude> ah hold ctrl
2014-03-29T12:36:28 < dongs> well, that moves net
2014-03-29T12:36:30 < dongs> im talkin about component
2014-03-29T12:36:36 < Claude> hmm do you mean draging a component?
2014-03-29T12:36:51 < Claude> ohh don't know . sorry never used that
2014-03-29T12:36:57 < dongs> yep. ehter move->drag or move->move all disconnects
2014-03-29T12:37:35 < dongs> You have to set your preferences to allow dragging tracks with a component. Go to Preferences>>PCB Editor>>Other>>Comp Drag, and select "Connected Tracks". Now when you use "move component" (shortcut MC), the tracks will drag with the component as long as they aren't locked.
2014-03-29T12:37:39 < dongs> hmm
2014-03-29T12:37:43 < dongs> lets try that
2014-03-29T12:38:01 < Claude> cool will try too :)
2014-03-29T12:38:41 < dongs> geeeeeeeez
2014-03-29T12:38:48 < dongs> it just moves tracks at like odd angles
2014-03-29T12:38:53 < dongs> FAIL
2014-03-29T12:39:25 < Claude> :)
2014-03-29T12:40:30 < dongs> but i learend something anyway
2014-03-29T12:40:41 < dongs> that edit->move is shortcutted as M->??
2014-03-29T12:40:44 < dongs> saves one key press
2014-03-29T12:40:46 < dongs> emd->md
2014-03-29T12:40:53 < Claude> maybe you can check the "restrict to 90/45" box in pcb editor -> interactive routng

2014-03-29T18:12:49 < Bird|otherbox> imagine smelling smoke in the cockpit and going to put your O2 mask on, only to find it is what is emitting the smoke, and the guy on the other side of the cockpit is in the same situation
2014-03-29T18:14:00 < superbia> what if you came on the plane stoned from the smoke !???
2014-03-29T18:14:55 < Bird|otherbox> superbia: wrong kind of smoke.
2014-03-29T18:15:12 < Bird|otherbox> O2 fires are really, really, *really* bad.
2014-03-29T18:29:11 < gnomad> has anyone found a *sensible* summary of MH370 to-date?

2014-03-29T18:36:24 < timemob> yes. its my dickstarter idea getting flushed down the shitter
2014-03-29T18:36:43 < timemob> it's a reverse hid dongle
2014-03-29T18:37:09 < timemob> virtual keyboard for assdroid/etc where you type on PC keyboard and phone receives it
2014-03-29T18:37:25 < gnomad> aah
2014-03-29T18:37:34 < timemob> so phone binds to dongle thinking it's s keyboard, PC send it keys.
2014-03-29T18:37:44 < gnomad> gotcha

2014-03-29T18:38:01 < timemob> I might still do zyps better idea tho

2014-03-29T20:41:10 < Steffanx> you should've used ugfx :P
2014-03-29T20:41:29 < Steffanx> but yeah. Even the demo on the f429 feels a bit slow.
2014-03-29T20:42:01 < mervaka> ever seen the stack during an EmWin operation?
2014-03-29T20:42:05 < mervaka> its like 10 calls deep

2014-03-31T04:20:41 < qyx_> any recommendation for low profile (<5mm) connector which is inherently waterproof to some level
2014-03-31T04:21:13 < qyx_> i mean that it wouldn't allow water to go into the device through it.. also some locking mechanism will be useful
2014-03-31T04:21:41 < qyx_> i am going to abuse sata if i don't find anything useful
2014-03-31T04:22:00 < dongs> heh
2014-03-31T04:22:00 < qyx_> micro usb isn't usable as it has holes inside
2014-03-31T04:22:09 < dongs> sata sounds good

2014-03-31T04:25:31 < qyx_> this kind of unholed sata looks good

2014-03-31T04:26:05 < dongs> 404
2014-03-31T04:26:13 < qyx_> although i bet it is made of some ungluable plastic
2014-03-31T04:26:15 < dongs> did farnell add referrerr protection
2014-03-31T04:26:28 < dongs> tired of image thieves
2014-03-31T04:26:41 < qyx_> hm, i found it on google images
2014-03-31T04:26:46 < qyx_> and farnell is down for maintenance
2014-03-31T04:26:49 < qyx_> maybe that
2014-03-31T04:27:21 < englishman> 5mm is pretty thin for waterproof
2014-03-31T04:27:33 < dongs> they wouldnt need maintenance if they ran windows

2014-03-31T04:28:42 < qyx_> like this without the holes
2014-03-31T04:29:39 < qyx_> englishman: semi-waterproof, i will be using 3.5mm TRRS also
2014-03-31T04:29:47 < qyx_> but it will be attached during use
2014-03-31T04:30:19 < qyx_> so i will use some rubber ring on it
2014-03-31T04:30:34 < dongs> qyx_: you need this http://www.digikey.com/product-detail/en/DBMM-25S-D/1003-1790-ND/2584969
2014-03-31T04:31:07 < qyx_> actually i was considering those small mini-d-sub connectors

2014-03-31T04:31:56 < dongs> so there's no holes
2014-03-31T04:32:01 < qyx_> its diameter is bigger that the whole device
2014-03-31T04:32:05 < dongs> lo
2014-03-31T04:33:24 < qyx_> *than the whole device thickness

2014-03-31T05:40:02 < dongs> if they're anywhere as ugly as stdperiphlib...

2014-03-31T05:49:40 < munki_> it's hard to control pwm using that though :\
2014-03-31T05:49:53 < dongs> ???
2014-03-31T05:49:56 < munki_> is this even possible? I need a 12mhz clock signal for an IC i'm interfacing with

2014-03-31T05:50:18 < dongs> like 2 lines if you just write to registers, or a few more if you use stdperiphlib

2014-03-31T06:17:08 < munki_> dongs: i tried, the signal is too noisy for my scope to pick up
2014-03-31T06:17:23 < dongs> there are different mco options
2014-03-31T06:17:27 < munki_> i see the square wave but i can't analyze
2014-03-31T06:17:29 < dongs> like /2 /8/whatever sysclk
2014-03-31T06:17:34 < dongs> isnt there
2014-03-31T06:17:39 < dongs> well, at least you arent running at 8mhz then
2014-03-31T06:18:22 < gxti> depends on the part, F1 doesn't have a divider for mco
2014-03-31T06:18:36 < gxti> but 72mhz is slow enough for any digital scope anyway
2014-03-31T06:18:37 < munki_> i'm using the f4discovery board
2014-03-31T06:18:45 < munki_> supposedly my sysclk is 100mhz
2014-03-31T06:18:57 < munki_> that is what my configuration leads me to believe
2014-03-31T06:19:06 < dongs> 100? not 168?
2014-03-31T06:19:11 < munki_> 100
2014-03-31T06:19:30 < munki_> i wanted to easily get 12.5mhz via dividers
2014-03-31T06:19:35 < gxti> f4 can divide mco by up to 5
2014-03-31T06:19:48 < gxti> but you should be able to see 100mhz unless your scope is absolute crap
2014-03-31T06:20:01 < munki_> i thought so
2014-03-31T06:20:04 < munki_> it is pretty nice
2014-03-31T06:20:09 < dongs> you have timer prescalers by 1 and period configuirable in 16bits... you can definitely do any mhz out of any sysclk
2014-03-31T06:20:16 < gxti> probably you're using it wrong. no offense.
2014-03-31T06:20:22 < munki_> probably
2014-03-31T06:20:44 < munki_> i have the probe ground clipped to a gnd pin, and the probe itself is hooked on PC9
2014-03-31T06:21:27 < gxti> sure. did you set the trigger level to somewhere in the middle like 1.5v? if it's not triggering then you would just see stuff scrolling by
2014-03-31T06:21:28 < dongs> http://bcas.tv/paste/results/hF5VCc48.html combination of divider and period and you can make some nice clocks
2014-03-31T06:21:51 < munki_> let me check
2014-03-31T06:22:05 < munki_> from what i saw it didn't look like it was reading that high of voltage anywhere

2014-03-31T08:13:33 < gxti> making a design footprint-compatible with either f1 or f3 is "fun"
2014-03-31T08:16:05 < emeb_mac> i can imagine
2014-03-31T08:16:21 < jpa-> what is the worst pin? :)
2014-03-31T08:16:44 < emeb_mac> power pins match up, but the I/O is nowhere close
2014-03-31T08:16:56 < gxti> so far nothing incompatible. i have 4 analog lines i want to feed into the SDADC but only 2 overlap so the other 2 go to two pads each
2014-03-31T08:17:10 < gxti> overlap with f1's boring regular adc that is
2014-03-31T08:17:27 < emeb_mac> ouch - F373 is even further afield
2014-03-31T08:17:38 < gxti> mco is different so that's doubled up. SDADC has an extra VDD and a reference that needs bypassing.
2014-03-31T08:18:55 < gxti> swdio lines up, how nice
2014-03-31T08:23:19 < emeb_mac> wonders never cease
2014-03-31T08:24:19 < gxti> oh right, i forgot i wanted usb on this. yeah not so much on that one.
2014-03-31T08:24:33 < gxti> it lines up... with the sdadc reference that needs bypassing
2014-03-31T08:24:57 < jpa-> haha
2014-03-31T08:25:07 < gxti> oh well, i was just trying this for the lulz anyway
2014-03-31T08:25:24 < jpa-> can always have some 0 ohm jumper resistors that are non-assembled on one board variant ;)
2014-03-31T08:26:02 < gxti> i would likely need two completely separate usb routes, just isn't worth it
2014-03-31T08:26:59 < emeb_mac> can't get there from here
2014-03-31T08:27:06 < jpa-> lulz denied

2014-03-31T08:31:01 < dongs> that japs TOTALLY RIPPED MY IDEA
2014-03-31T08:31:38 < emeb_mac> tricksy they are
2014-03-31T08:32:47 < gxti> oh, i was wrong about the usb thing. the column for LQFP48 is on the opposite sides for the two datasheets so i was looking at the wrong thing. usb overlaps.
2014-03-31T08:32:53 < gxti> still not sure i care though.
2014-03-31T08:32:57 < dongs> usb overlaps iwsht wat
2014-03-31T08:33:05 < dongs> oh 373
2014-03-31T08:33:08 < dongs> such shit mcu
2014-03-31T08:33:14 < gxti> o rly
2014-03-31T08:33:21 < gxti> and why does your dongness dislike it
2014-03-31T08:33:24 < emeb_mac> what's wrong with it?
2014-03-31T08:33:25 < dongs> well unless you acutally need sdacd
2014-03-31T08:33:30 < dongs> sdacd
2014-03-31T08:33:34 < dongs> just that
2014-03-31T08:33:35 < emeb_mac> oh, right
2014-03-31T08:33:40 < dongs> and its pin incompatible wiht EVERYTHING
2014-03-31T08:33:42 < emeb_mac> fewer usable pins
2014-03-31T08:33:54 < emeb_mac> due to all the extra grounds and references
2014-03-31T08:34:01 < dongs> emeb_mac: i used one of your 373 breakout boards as host for some pogo pins yesterday
2014-03-31T08:34:09 < emeb_mac> kewl
2014-03-31T08:34:14 < dongs> (without mounting anything else
2014-03-31T08:34:15 < gxti> and yes, SDADC was the entire reason i was looking at it
2014-03-31T08:34:32 < gxti> designing for f103 but with the possibility to drop in f373 for adc upgrade
2014-03-31T08:34:36 < emeb_mac> i did some tests of SDADC a few months back - seemed to work OK
2014-03-31T08:34:43 < gxti> might still be possible but i don't think i can even make use of those extra bits
2014-03-31T08:34:46 < dongs> right, but the "drop in" part isnt gonna work
2014-03-31T08:34:53 < dongs> you either do 373 or 103
2014-03-31T08:34:59 < dongs> i dont think they're even power pin compatible
2014-03-31T08:35:13 < gxti> it's not an exact match but you can give up some more IOs to do it
2014-03-31T08:35:33 < gxti> anyway i no longer care for this project
2014-03-31T08:35:43 < emeb_mac> so fickle

This is something that I thought about before getting the procedure done and I made a conscious decision to get the implant anyway. I also figure that if I'm ever incapacitated and put in an MRI machine without the ability to give the doctor any forewarning, a tiny magnet getting ripped out of my finger will be the least of my co

2014-03-31T12:19:31 < FreezingCold> yeah I was thinking just match the clock and then watch the RAM

2014-03-31T14:03:00 < madisk> if you're suicidal you have mental issues. you're not sane.
2014-03-31T14:03:18 < madisk> being not-alive has absolutely no advantages over being alive.
2014-03-31T14:03:52 < Steffanx> that is what your ~sane mind makes of it
2014-03-31T14:04:17 < dongs> sure it has
2014-03-31T14:04:21 < dongs> youre not wasting my air
2014-03-31T14:04:31 < Steffanx> Yes and you no longer have to deal with dongs.
2014-03-31T14:04:36 < dongs> ^_^
2014-03-31T14:05:51 < Steffanx> Foxconning didn't drive you crazy yet dongs?
2014-03-31T14:05:54 < Steffanx> *more crazy
2014-03-31T14:06:28 < madisk> what does dongs do at foxconn ? counsel the suicidal ?
2014-03-31T14:08:08 < dongs> yes.
2014-03-31T14:08:13 < dongs> adjust the nets.
2014-03-31T14:08:19 < jpa-> madisk: so in a situation where you would be in constant pain and know that soon enough you will die anyway, suicide would still offer no benefits?
2014-03-31T14:08:30 < Steffanx> Hired by microsoft to ruine the reputation of apple. Sounds like it.
2014-03-31T14:08:38 < madisk> jpa-: while you're alive you can do *something*. when you're dead you can't.
2014-03-31T14:08:41 < dongs> jpa-: ,there are better solutions in that situation
2014-03-31T14:08:54 < madisk> so yeah, if I was in constant terminal pain, I still wouldn't consider suicide.
2014-03-31T14:09:19 < Steffanx> even when you know that would turn in into Flyback ?!
2014-03-31T14:09:19 < madisk> that's the theory.
2014-03-31T14:09:35 < dongs> flyback would probably be better off dead.
2014-03-31T14:09:38 < madisk> in reality one might not be strong enough.
2014-03-31T14:09:39 < Steffanx> *you
2014-03-31T14:09:50 < madisk> flyback has no problems. he's just a spoiled child.
2014-03-31T14:09:59 < jpa-> that's a problem
2014-03-31T14:10:07 < Steffanx> He has serious problems, at least that's what he says.

2014-03-31T14:10:54 < Steffanx> lol you know all about it. :D
2014-03-31T14:14:41 < jpa-> madisk: all just boils down to the definition of "benefit"
2014-03-31T14:15:29 < madisk> jpa-: which is why acceptance is a virtue and comparison/judgement results in pain.
2014-03-31T14:16:03 < jpa-> pain is not necessarily bad, and not wasting dong's air is definitely a benefit
2014-03-31T14:20:49 < Laurenceb__> dongs actually works for foxconn?
2014-03-31T14:21:52 < Laurenceb__> ive got confused as to where the trolling stops

2014-03-31T16:30:38 < aadamson> anyone played with minum voltage to make usb work?  reason I ask, I've got an stm32l1 that is running on 2.0v.  At that level, usb vcp won't come up and register on windows, power it with 3v3 and it does... no other changes.
2014-03-31T16:31:14 < aadamson> *different power supply with 3v3* that 2.0v so it certainly may be that, but just curious, st says usb will work at 2.0v, but I'm not sure I'm buying it
2014-03-31T16:31:50 < aadamson> sheesh, and if I could type this morning... minim = minimum ^
2014-03-31T16:34:02 < Laurenceb__> i think they mean that the hardware will work
2014-03-31T16:35:32 < GargantuaSauce> yeah the host will still be expecting 3V signalling

2014-03-31T16:44:43 < zyp> aadamson, usb is using 3.3V signalling, so with an internal PHY you can't expect it to work without the proper supply voltage

2014-03-31T16:49:14 < aadamson> yeah I know... funny the datasheet for the l1 says that at the 2.0-2.4 range, usb is functional with the caveot that the min vdd is 3.0v on the specification... I suspect they need to revise their sheet and remove usb functional on the 2.0-2.4v, leave it on the 2.4-3.6 with the caveot

2014-03-31T16:52:40 < englishman> functional, but not compliant :)
2014-03-31T16:53:06 < Laurenceb__> smps for the pull up :P
2014-03-31T16:53:10 < englishman> would be cool if you could have a separate VddIO like avrs
2014-03-31T16:54:40 < aadamson> pull up part is working just fine... I can cause the connect/disconnect event to occur with 2.0v, but no data moves across the buss
2014-03-31T16:55:08 < aadamson> it's a differential bus so I suspect that +/- 2.0v just aint gonna cut it...
2014-03-31T16:56:10 < englishman> by usb functional they mean you can start the peripheral and it can work...
2014-03-31T16:56:18 < aadamson> but hey, for a science experiment, I'm gonna see what the bench supply says... if I can dust off a very old HP supply - and have it still work
2014-03-31T16:56:30 < englishman> but they state it is not compliant, so if your computer demands 3v signalling, not much you can do about that :)
2014-03-31T16:56:50 < englishman> avr > st in this regard :)
2014-03-31T16:57:22 < aadamson> yeah, I'm going to try a different port just for kicks. how so on the AVR not all the avrs have usb in the core?
2014-03-31T16:57:39 < englishman> but the ones that do, you can power the usb peripheral separately, ie from the usb voltage

2014-03-31T16:57:57 < aadamson> yeah
2014-03-31T16:58:47 < aadamson> but 32 bits trumps 8 any day in my book, especially with what you can do with it... and let's not forget all the dang peripherals... pluses and minuses, it's still an STM win :) (or should I say an ARM win)
2014-03-31T16:59:10 < englishman> could still do some dual power supply stuff to raise chip Vdd when usb is plugged in
2014-03-31T16:59:37 < englishman> but then i guess you have to check out the other gpio voltages are in spec for whatever it's connected to
2014-03-31T16:59:40 < MrMobius> for arguments sake it is sometimes easier to emulate 8 bit systems on 8 bit systems from what I have heard
2014-03-31T16:59:59 < aadamson> it's not worth it... usb was just a debugging advantage, I'll just use SWO for now...
2014-03-31T17:00:07 < aadamson> it was one of the unknowns anyway...
2014-03-31T17:00:08 < MrMobius> dont have to waste time and cycles trimming registers and setting flags if the 9th bit is set, etc
2014-03-31T17:00:12 < aadamson> now somewhat a known
2014-03-31T17:00:18 < zyp> usb isn't really differential, SS aside
2014-03-31T17:03:10 < zyp> (both lines low is also a valid state, used to terminate packets)
2014-03-31T17:03:18 < aadamson> englishman, I may look at just a usb adapter for it with the multi power supply, I have one component on the board that I can't power with > 1.8v so I have provisioned for a separate buss for that anyway
2014-03-31T17:03:51 < aadamson> yes, true, it's not a true differential
2014-03-31T17:04:09 < scrts_w> did someone try to measure the current of the circuit powered by PWM?

2014-03-31T17:35:16 < dongs> < englishman> would be cool if you could have a separate VddIO like avrs
2014-03-31T17:35:18 < dongs> what
2014-03-31T17:35:56 < dongs> the only atmel trash with vddio is like... not AVRs
2014-03-31T17:36:01 < englishman> like 32u4
2014-03-31T17:36:11 < englishman> with separate internal vreg for usb periph
2014-03-31T17:36:23 < dongs> but its not a stepdown/boost
2014-03-31T17:36:30 < englishman> no.
2014-03-31T17:36:35 < englishman> but theres 5v on usb
2014-03-31T17:36:36 < dongs> so its useless below 5V anyway.
2014-03-31T17:37:43 < englishman> that's not the idea
2014-03-31T17:38:12 < dongs> vddio to me means voltage i/o pins run at
2014-03-31T17:38:20 < dongs> and thats always vdd on avrturd anyway.
2014-03-31T17:38:34 < englishman> VddUSB then
2014-03-31T17:38:41 < dongs> aadamson: y u need to run off 2.0V while usb is connected anyway
2014-03-31T17:39:04 < dongs> acutally fuck avr
2014-03-31T17:39:06 < dongs> im gonna go take a bath
2014-03-31T17:41:49 < madisk> do you have a webcam ?
2014-03-31T17:43:28 < aadamson> I can run the stm at 3v3 when on usb as long as I don't put 3v3 on the one part that will only run at 1.8...
2014-03-31T17:43:46 < aadamson> but usb was only there for development, the target will run at 2.0v normally
2014-03-31T17:44:10 < aadamson> so I'll work around it, not a big deal, just wasted one whole day mucking with vcp that I should have known better...
2014-03-31T17:44:23 < aadamson> amazing what you think about when you are sleeping :)...

2014-03-31T18:08:40 < zyp> except tape&reel and weird variants
2014-03-31T18:08:56 < dongs> yeah T&R are all nonstock
2014-03-31T18:08:58 < dongs> but singles arent
2014-03-31T18:08:59 < dongs> hm
2014-03-31T18:09:12 < zyp> mouser have qfp64 in stock
2014-03-31T18:09:22 < dongs> not that much
2014-03-31T18:09:30 < effractur> well just get the 415
2014-03-31T18:09:31 < zyp> but they are significantly more expensive, for once
2014-03-31T18:09:34 < effractur> or is that one omre expensive
2014-03-31T18:09:41 < dongs> 415 is only 80mhz no?
2014-03-31T18:09:45 < zyp> effractur, export restrictions
2014-03-31T18:09:51 < Steffanx> no that is the 401
2014-03-31T18:09:52 < effractur> 415 is just with crypto and some export stuff
2014-03-31T18:10:01 < dongs> o yea
2014-03-31T18:10:13 < zyp> yeah, only difference is crypto and related export bullshit
2014-03-31T18:10:24 < effractur> you what countrys is it forbidden
2014-03-31T18:10:30 < effractur> i only think like iran and stuff

2014-03-31T18:12:11 < karlp> the problem is that list is not the same list that digikey actually uses :|

2014-03-31T18:13:47 < karlp> yeah, what he said
2014-03-31T18:13:54 < dongs> mouser happily exports F415 to me
2014-03-31T18:13:54 < effractur> i see
2014-03-31T18:13:59 < dongs> and various accelerometers
2014-03-31T18:14:06 < dongs> digieky refuses to
2014-03-31T18:14:10 < effractur> strange

2014-03-31T18:14:23 < karlp> fuck digikunt in the arse
2014-03-31T18:14:24 < dongs> many years ago digieky actually refused to export me some seiko epson RTC chip
2014-03-31T18:14:36 < dongs> i ordered it once.. and it didnt show up
2014-03-31T18:14:40 < dongs> i ordered it agian.. it didnt show up
2014-03-31T18:14:52 < zyp> norwegian digikey doesn't even list a bunch of stuff
2014-03-31T18:15:01 < dongs> thirsd time i finally noticed when i switched currency ot whatever it showed a little red text above order that "some items were removed bla bla"
2014-03-31T18:15:09 < dongs> yeah, if you search for that shit on my digikey, it doesnt list it
2014-03-31T18:15:15 < karlp> yeah, we don't have a localised digikey.
2014-03-31T18:15:31 < dongs> but you can list in usa one and add to cart, but if you switch currency/ wahtever it will remove the noncompliant shit
2014-03-31T18:15:32 < effractur> and farnell?
2014-03-31T18:15:45 < zyp> karlp, you don't get free shipping either?
2014-03-31T18:16:02 < karlp> farnell accepted my order, then called and asked for paperwork, and that was..... 8 months ago
2014-03-31T18:16:11 < karlp> no reply anymore ffrom them
2014-03-31T18:16:22 < effractur> what paperwork, export stuff?
2014-03-31T18:16:32 < karlp> yeah, promisign not to make ICBMs in iceland

2014-03-31T18:17:21 < zyp> last one was for f429-disco, ordered from RS, got a UK export restriction form to fill out
2014-03-31T18:17:40 < karlp> and they actually sent it after filling out the forms?
2014-03-31T18:17:43 < karlp> that would have been nice.

I did a new board, SWD works fine, I ran the there jtag pins to the header, but when I tried to establish a jtag interface connection the debugger stops.  This is with j-link, same thing happens with stlink
2014-03-31T20:42:36 < aadamson> was I supposed to provide signal conditioning or cross any of the connections?

2014-03-31T20:50:07 < aadamson> and obviously on the nrst pin of the jtag

2014-03-31T20:52:55 < gxti> if you don't want to wire it to the adapter it should be floating or pulled up
2014-03-31T20:53:05 < gxti> default config is ok as long as nothing is driving the pin
2014-03-31T20:53:15 < aadamson> ah, it used as gpio...
2014-03-31T20:53:20 < aadamson> as an input
2014-03-31T20:54:40 < aadamson> I'll have to see how what its connected too is driving it...
2014-03-31T20:55:23 < aadamson> it connected to another GPIO on another part, so to use 4 wire jtag, that needs to be floating or pulled up yes?
2014-03-31T20:55:58 < aadamson> not that I really care mind you, as I'll mostly be using swd, but I'm just trying to verify a design and that stuck out at me...
2014-03-31T20:56:14 < gxti> ideally yes, i'm not 100% sure. i think there might be a way to disable it from software (on f1 it would be pin remap)
2014-03-31T20:56:33 < aadamson> ah, I'll look this is on the l1
2014-03-31T20:56:35 < gxti> i haven't actually done jtag for stm32 before
2014-03-31T20:59:38 < Steffanx> i don't really see the need for jtag. Or do you want ot use the boundary scan stuff aadamson ?
2014-03-31T21:00:30 < aadamson> no, I agree, just wanted to make sure everything was working.. when I spin the design, I'll get rid of one of those, the one pin is SWO I believe so I'll need to keep that
