2014-07-01T01:44:18 < __rob> thanks Steffanx
2014-07-01T01:44:39 < __rob> the driver seems pretty ropey at best..

2014-07-01T01:44:59 < __rob> apart from the user implementation, TI's own stuff... just looking at the forum
2014-07-01T01:46:44 < SlaveToTheSauce> i have a cc3k gathering dust also because i looked at the code they provide
2014-07-01T01:47:17 < SlaveToTheSauce> but whatever it was free!
2014-07-01T01:47:37 < __rob> seems to be alot of spi driver attempts. most of them a cut and paste job of each other or TI's examples..

2014-07-01T01:50:45 < Steffanx> Yes the most important feature of the cc3000 is the reset :P
2014-07-01T01:51:32 < __rob> what kind of message rate can you get with this module ?

2014-07-01T01:51:48 < __rob> thats all I really want to test, minimal packet size, just getting them through quick
2014-07-01T01:52:32 < __rob> tried a zigbee module, but wasn't upto the task. best I could get was around 60 4 byte messages a second

2014-07-01T02:00:41 < SlaveToTheSauce> i am a fan of the nrf24l01, super simple to operate
2014-07-01T02:05:51 < dongs> sup blogs
2014-07-01T02:12:17 < Thorn> what is going on with this tablet. when I use supplied USB cable to connect it to the AC charger, it actually charges. any other cable -> slow charge(or discharge) like in USB mode but it still says "Charging (AC)"
2014-07-01T02:12:35 < Thorn> how it the supplied cable different from others
2014-07-01T02:13:10 < __rob> 200-300 messages a second around 10 bytes each
2014-07-01T02:13:14 < dongs> is it charge only cable?
2014-07-01T02:13:18 < dongs> (no data
2014-07-01T02:13:23 < Thorn> no, it works for data
2014-07-01T02:13:29 < dongs> wtf
2014-07-01T02:14:05 < Thorn> just checked, it does
2014-07-01T02:15:13 < Thorn> shitty thin cable with no ferrite things on it, what do I do if it breaks
2014-07-01T02:15:30 < englishman> get a new tablet obviously
2014-07-01T02:15:36 < englishman> they are useless in <12 months anyway
2014-07-01T02:15:48 < SlaveToTheSauce> __rob: do check out that chipset then. you can get a breakout with 100mW amplifier for like 6 bucks
2014-07-01T02:17:42 < __rob> yea, I'll take a look, thanks
2014-07-01T02:17:48 < __rob> will give this cc3000 another day or two
2014-07-01T02:17:51 < __rob> see how it goes
2014-07-01T02:18:44 < __rob> Ideally i'd like to get it to work with freertos, replace all the busy waits with some semaphores
2014-07-01T02:19:11 < __rob> slightly expecting it to all break nicely when I do that now though
2014-07-01T02:22:23 < dongs> the new ST timecube shit seems fucking annoying
2014-07-01T02:22:31 < dongs> why did they have to ruin stdperiphlib
2014-07-01T02:25:20 < emeb> because reasons

2014-07-01T02:54:10 < gxti> fascinating?
2014-07-01T02:56:30 < Thorn> in my experience it flashes when you touch the board because uart rx is floating or something

2014-07-01T05:08:30 < jadew> hey guys, I'm just going to start with STM32, any suggestions for an IDE?
2014-07-01T05:12:07 < jadew> do I even need an IDE or can I just go with GCC + some editor I like?
2014-07-01T05:13:41 < SlaveToTheSauce> yes that is certainly an option
2014-07-01T05:15:05 < jadew> I see. How do I upload the firmware tho? is there some tool for that? (again, complete noob - just powered on a discovery board)
2014-07-01T05:15:17 < SlaveToTheSauce> what os
2014-07-01T05:15:23 < jadew> windows mostly
2014-07-01T05:16:10 < SlaveToTheSauce> http://www.st.com/web/en/catalog/tools/PF258167 http://www.st.com/web/en/catalog/tools/PF258168
2014-07-01T05:16:27 < jadew> awesome, thank you
2014-07-01T05:17:44 < SlaveToTheSauce> some of your fellow micro-slaves use the keil toolchain, might want to check that out but the free license is limited
2014-07-01T05:18:19 < jadew> SlaveToTheSauce, yeah, I found an article recommending it but it said the free version is limited to 32k binaries
2014-07-01T05:18:24 < SlaveToTheSauce> yup
2014-07-01T05:18:47 < jadew> I suppose that's the best IDE out there, eh?
2014-07-01T05:19:20 < SlaveToTheSauce> some people use eclipse but i don't think that's a tolerable option personally
2014-07-01T05:19:31 < jadew> yeah, I don't like it either
2014-07-01T05:21:31 < jadew> is the code cross compilable between the keil compiler and gcc?
2014-07-01T05:22:08 < SlaveToTheSauce> if written correctly it should be
2014-07-01T05:22:27 < jadew> so no wacky structures that are only present on keil and things like that?
2014-07-01T05:23:04 < jadew> wasn't expecting to find such a big variety of toolchains
2014-07-01T05:23:28 < SlaveToTheSauce> well there's a whole stack of libraries that keil comes with i think? you'd have to forego those to maintain gcc compatibility
2014-07-01T05:24:07 < jadew> yeah, I'd rather stay away from that sort of stuff
2014-07-01T05:24:44 < jadew> thanks
2014-07-01T05:26:10 < SlaveToTheSauce> i guess llvm/clang is an option too (and keil is moving there soon?) but i don't know much about it
2014-07-01T05:26:20 < dongs> keil works ok, and you can do --c99 and --gnu with it to allow retarded gcc extensions
2014-07-01T05:26:32 < dongs> just avoid inline asm (doesn't work, isn't necessary in 2014 either)
2014-07-01T05:26:43 < jadew> you'd be surprised
2014-07-01T05:26:54 < jadew> but good to know

2014-07-01T05:27:24 < SlaveToTheSauce> dongs is our resident protroll and ms fellating expert
2014-07-01T05:27:37 < dongs> i'd like to hear your reasoning for inline asm in 2014
2014-07-01T05:27:42 < dongs> and why its needed or necessary
2014-07-01T05:27:52 < dongs> chances are, the only reason you wanna use inline asm is because your compiler sucks dick
2014-07-01T05:28:41 < jadew> well, I'm new to ARM, but if I were to choose a few reasons: perfect timing and yes, crappy compiler
2014-07-01T05:28:49 < jadew> and they're all crappy
2014-07-01T05:28:54 < dongs> perfect timing?
2014-07-01T05:29:02 < dongs> thats why there's hardware to do shit like this.
2014-07-01T05:29:04 < englishman> timers do timing pretty well
2014-07-01T05:29:05 < jadew> clock perfect timing
2014-07-01T05:29:21 < jadew> they don't do 2 ticks delays
2014-07-01T05:29:23 < jadew> or 3 ticks
2014-07-01T05:29:25 < jadew> or whatever
2014-07-01T05:29:28 < dongs> you'd be surprised
2014-07-01T05:29:30 < jadew> takes more to set them up
2014-07-01T05:29:43 < dongs> chances are, if you need a 2 tick delay, youre doing it wrong anyway.
2014-07-01T05:29:49 < dongs> because you're doing something that hardware should be doing anyway.
2014-07-01T05:30:15 < jadew> now you're making a lot of assumptions
2014-07-01T05:30:35 < jadew> there are plenty of situations in which hardware can't do whatever you want to do
2014-07-01T05:31:01 < jadew> like when you're trying to support a protocol and your chip is barely fast enough
2014-07-01T05:31:07 < dongs> maybe on avr
2014-07-01T05:31:09 < dongs> then youre using wrong chip
2014-07-01T05:31:15 < jadew> no
2014-07-01T05:31:18 < dongs> yes
2014-07-01T05:31:21 < jadew> best chip is the cheapest that can do the job

2014-07-01T05:31:51 < jadew> if you pick anything else, that's when you're doing it wrong
2014-07-01T05:32:59 < dongs> i have a PWM dimmer running on stm32f103cb
2014-07-01T05:33:04 < dongs> firmware is like 2k of code.
2014-07-01T05:33:12 < dongs> for sure i could have used some atmel garbage to do same shit BUT
2014-07-01T05:33:22 < dongs> it would cost me more in time figuring out the garbage toolchain and programming tools.
2014-07-01T05:33:30 < dongs> so, no
2014-07-01T05:33:44 < jadew> hobby projects can accomodate ANYTHING

2014-07-01T05:34:06 < jadew> there are lots of people using arduinos in comercial products, it doesn't mean they're doing it right
2014-07-01T05:34:12 < jadew> it just means they don't know better
2014-07-01T05:35:08 < jadew> anyway, point out exceptions to disprove a general point doesn't really work
2014-07-01T05:35:23 < jadew> cheapest chip that can do the job is always the perfect chip
2014-07-01T05:35:31 < jadew> that of course includes development time and all that
2014-07-01T05:35:35 < jadew> it all has to be factored in
2014-07-01T05:35:48 < jadew> but on big production runs, development time gets less important
2014-07-01T05:36:14 < jadew> *pointing
2014-07-01T05:44:47 < dongs> some people use lunix
2014-07-01T05:44:49 < dongs> it ticks all teh boxes
2014-07-01T05:44:53 < dongs> free, shit
2014-07-01T05:46:42 < jadew> what do you mean?
2014-07-01T05:47:18 < dongs> most of hte time, when lunix is used for task X, its only done so beacuse its free
2014-07-01T05:47:35 < dongs> but that doesnt make it any less shit
2014-07-01T05:48:22 < jadew> of course, but if it means it saves money in the long run (from a business perspective), that's fine
2014-07-01T05:48:27 < dongs> same for AVR/other useless shit. avr costr hasn't been a factor in developing something in years
2014-07-01T05:48:35 < dongs> there are tons of cheaper cortex m3/m0 chips
2014-07-01T05:48:40 < dongs> no it doesnt
2014-07-01T05:48:53 < dongs> you have to keep some neckbeard hired to write some shitty python scripts
2014-07-01T05:49:03 < jadew> no you don't
2014-07-01T05:49:17 < SlaveToTheSauce> no u
2014-07-01T05:49:31 < jadew> linux is cheaper as a server - you save a ton right there
2014-07-01T05:50:02 < dongs> or if you're a device manufacturer for example, maintaining lunix drivers for your stuff is a fucking nightmare
2014-07-01T05:50:13 < jadew> now depending on what you're planning to run on that server, you can even ignore the fact that it's a linux box
2014-07-01T05:50:21 < dongs> because lunix fucks change kernel api/abi more often than they change their underwear (bad analogy really since some of them dont change for months)
2014-07-01T05:50:39 < jadew> dongs, that's true and if you (as a manufacturer) believe it's not worth while, you don't
2014-07-01T05:51:01 < jadew> it's not your problem if people chose to use free stuff that doesn't give a crap about backward compatibility
2014-07-01T05:51:12 < johntramp> hi,   are any of you able to help me understand what the different datatypes are for in the aes crypto processor?

2014-07-01T05:51:43 < jadew> dongs, what's your point tho?

2014-07-01T05:52:04 < johntramp> dongs: sorry, what do you mean?
2014-07-01T05:52:04 < dongs> i rarely have a point
2014-07-01T05:52:12 < jadew> heh, ok, sadly for you we share that opinion about linux
2014-07-01T05:52:41 < dongs> johntramp: just kidding. whats the question. doesnt reeference manual explain all that shit
2014-07-01T05:53:54 < johntramp> ah :)    well it probably is my lack of understanding of crypto,  but why would you want to use swapping of the input data?
2014-07-01T05:54:51 < dongs> probably because of endianness?
2014-07-01T05:56:03 < johntramp> ah ok,  so it is just to ease compatibility with other systems?
2014-07-01T05:56:53 < dongs> that would be my guess. if youre in control of protocol on both ends, then it doesnt matter.
2014-07-01T05:59:16 < johntramp> yeah that makes sense   cheers :)
2014-07-01T06:11:00 < PaulFertser> dongs: kernel devs do not break drivers that are properly submitted upstream; you're right that maintaining an out-of-tree driver is a real pita. But sane manufacturers just submit upstream.
2014-07-01T06:15:02 < PaulFertser> karlp: my milandr repo is ~useless, it has just the very first steps of supporting the on-chip peripherals, and nobody seemed to be interested (so I'm refusing to work on any project with milandr at work now).

2014-07-01T07:51:08 < SlaveToTheSauce> ya there is a bit of a correlation between free shipping and mangled items oddly enough
2014-07-01T07:52:46 < upgrdman> damn. that sux
2014-07-01T07:53:03 < upgrdman> i opened a case through ebay
2014-07-01T07:53:32 < upgrdman> seller replied "i would like to send you a replacement. pls close the case and email me." lol. retards.
2014-07-01T07:57:36 < dongs> upgrdman: sure.
2014-07-01T07:57:42 < dongs> close it after he sends a replacement and yo ahve tracking
2014-07-01T07:57:47 < upgrdman> exactly
2014-07-01T07:57:58 < dongs> otherwise he has no incentive to do so :)
2014-07-01T07:58:00 < upgrdman> although not just tracking
2014-07-01T07:58:04 < upgrdman> what if i get another broken one
2014-07-01T07:58:16 < upgrdman> im not closing till a new one arrive, or a refund is issued
2014-07-01T07:58:21 < rewolff2> upgrdman: Instead of the discovery-hack, next time you can get a nucleo. I'm guessing they didn't exist when you got the F4-disco.

2014-07-01T08:05:27 < upgrdman> then i try to connect with official st-link windows program, and it keep losing connectino
2014-07-01T08:06:41 < upgrdman> does the chip keep track of write cycles to it's flash?

2014-07-01T08:15:28 < SlaveToTheSauce> i dunno about st-link but oocd has a specific verify_flash command that would probably be useful
2014-07-01T08:17:54 < upgrdman> official st-link claims my .bin and the actual flash match :(
2014-07-01T08:18:29 < upgrdman> i suppose i could start by redoing all the solder joints on my lcd/lcd breakout, and add a decoupling cap aside from whats on the PFC

2014-07-01T08:58:39 < GargantuaSauce> have to search

2014-07-01T08:59:12 < emeb_mac> twist it and turn it every which way and you still can't get it to line up right
2014-07-01T08:59:42 < GargantuaSauce> wait is there no timecube for the f1?
2014-07-01T08:59:46 < GargantuaSauce> does that mean it's nearing end of life?
2014-07-01T08:59:56 < emeb_mac> I saw that too - wtf?
2014-07-01T08:59:59 < dongs> as one of my pals said, <pal> STM works very hard at screwing up their web site.  I should have known better not to include a link to their shit from my commit log.
2014-07-01T09:00:28 < dongs> emeb_mac: who cares, timecube is dead on arrival. so much aids, you're better off just using chibios or something.
2014-07-01T09:00:47 < dongs> if oyu're into HALs and premade nonflexible drivers and hsit

2014-07-01T09:01:40 < dongs> its probably still the same shitty "dont use, dont touch ST liberty license" crap
2014-07-01T09:01:54 < GargantuaSauce> ya it looks like halfassed class wrappers for stdperiph
2014-07-01T09:01:57 < GargantuaSauce> do not want
2014-07-01T09:02:00 < upgrdman> ok so this is the weird problem i'm having with an lcd. any ideas?   https://www.youtube.com/watch?v=Srw9CB7EdUU
2014-07-01T09:02:27 < dongs> upgrdman: wires2long
2014-07-01T09:02:29 < GargantuaSauce> this is like an 8080 interface right?
2014-07-01T09:02:29 < dongs> really.
2014-07-01T09:03:34 < emeb_mac> cool jumpers bro
2014-07-01T09:03:38 < GargantuaSauce> ya looks like a timing/signal thing
2014-07-01T09:04:30 < upgrdman> ok
2014-07-01T09:04:35 < GargantuaSauce> but then again i got decent results with a not much less ghetto setup
2014-07-01T09:04:35 < upgrdman> ya, 16bit 8080
2014-07-01T09:05:06 < upgrdman> i added lots of NOP waiting between all gpio changes, thinking timing issues, but the problem stayed the same.
2014-07-01T09:05:13 < upgrdman> will try shorter jumpers anyway
2014-07-01T09:05:58 < dongs> that shit has no fsmc?
2014-07-01T09:06:03 < GargantuaSauce> are the gpios set to the highest speed setting / lowest drive impedance?
2014-07-01T09:06:09 < GargantuaSauce> try kicking that down a notch
2014-07-01T09:06:26 < upgrdman> f0, no fsmc
2014-07-01T09:06:46 < upgrdman> ya, set to 50mhz, max on the f0. will try slower.
2014-07-01T09:07:02 < dongs> with those wire, you should tr slower.
2014-07-01T09:08:12  * emeb_mac wonders - does chibios have usb host drivers for stm32?
2014-07-01T09:08:17 < dongs> haha
2014-07-01T09:08:28 < emeb_mac> libopencm3 doesn't
2014-07-01T09:08:43 < emeb_mac> just device
2014-07-01T09:08:51 < upgrdman> hmm. tried 10mhz and 2mhz modes. no difference :(
2014-07-01T09:09:04 < GargantuaSauce> is there decoupling on the lcd's power after the jumpers?
2014-07-01T09:09:06 < GargantuaSauce> there really should be
2014-07-01T09:09:10 < upgrdman> will ghetto rig some shorter wires tomorrow
2014-07-01T09:09:43 < upgrdman> on the PFC, but that's it. will add a ceramic 104 tomorrow.
2014-07-01T09:10:02 < GargantuaSauce> definitely kind of a weird issue in any case
2014-07-01T09:10:07 < GargantuaSauce> http://workman-industries.net/images/f4_cube.jpg isn't much less halfassed by any means
2014-07-01T09:10:15 < GargantuaSauce> and no issues with that setup
2014-07-01T09:10:34 < upgrdman> nice
2014-07-01T09:10:48 < upgrdman> maybe i can find a ribbon cable at work
2014-07-01T09:11:10 < upgrdman> so is the purpose of slower slew rates when using long wires to help min the inductive coupling between wires?
2014-07-01T09:12:45 < emeb_mac> long wires w/ fast signals & bad impedance match mean ringing at the transitions.
2014-07-01T09:13:02 < GargantuaSauce> yeah a dangly jumper will ring like a bell, no coupling required
2014-07-01T09:13:20 < GargantuaSauce> there's also capacitive coupling and probably the power is drooping

2014-07-01T09:14:24 < GargantuaSauce> because afaik an lcd is driven at a reasonably high voltage and there's charge pumps in the driver to do that. doesnt play well with inductance on the supply
2014-07-01T09:15:34 < upgrdman> k
2014-07-01T09:15:50 < GargantuaSauce> and since of course the input signals are referenced to that driver's ground/vcc they're going to be clobbered

2014-07-01T09:17:57 < upgrdman> good idea
2014-07-01T09:21:02 < GargantuaSauce> also it could be as simple as one of the data lines' jumpers being open and thus the input is floating and getting whatever value through capacitive coupling with the clock and adjacent data lines
2014-07-01T09:21:32 < upgrdman> ya. was planning to resolder my breakout board joints, and reseat each jumper.
2014-07-01T09:22:03 < upgrdman> too late and i gotta be up early. will try tomorrow and see what comes of it.
2014-07-01T09:22:13 < upgrdman> thanks for the tips guys.
2014-07-01T09:22:23 < GargantuaSauce> no problemo, keep us posted!

2014-07-01T09:25:15 < GargantuaSauce> also the cable is http://www.ebay.ca/itm/251158780560 (from a different source)
2014-07-01T09:25:24 < GargantuaSauce> i have like 5-6 because they're so ridiculously handy
2014-07-01T09:26:27 < GargantuaSauce> and i find crimping tedious as hell

2014-07-01T17:39:14 < _franck__> I need to make a choise between libopencm3 and ST libraries
2014-07-01T17:39:54 < _franck__> the big part of my firmware will be an USB Ethernet device
2014-07-01T17:40:07 < _franck__> it's not implemented in neither lib
2014-07-01T17:40:10 < Steffanx> That choice is all up to you. Some prefer libopencm3 others prefer ST stuff. Don't know about the ethernet support of libopencm3
2014-07-01T17:40:23 < _franck__> but I need to figure out what's best to start with
2014-07-01T17:40:47 < karlp> some people like reading the sheets and writing it all themselves.
2014-07-01T17:40:55 < Steffanx> Yeah.
2014-07-01T17:41:00 < _franck__> I'll go for libopencm3 after I saw some part of the ST code with all the obscure typedefs
2014-07-01T17:41:12 < karlp> what are you making that you want to be a usb ethernet device?
2014-07-01T17:41:18 < karlp> which class are you looking at?
2014-07-01T17:41:36 < _franck__> CDC ECM
2014-07-01T17:42:22 < _franck__> and I 'll also need mass storage
2014-07-01T17:42:29 < _franck__> all this in a composite device
2014-07-01T17:43:24 < karlp> for my own interest, what makes you choose ECM over EEM/NCM? and what is the use case that you want to present as an ethernet device?
2014-07-01T17:43:40 < _franck__> I'm used to microchip where USB stuff are easy (lot of examples and class already implemented)
2014-07-01T17:44:23 < _franck__> I don't have the choise. That will be an ethernet device over USB. I didn't choose that.
2014-07-01T17:45:09 < _franck__> as for ECM or EEM/NCM I'm not sure. I need the simpliest one. And I think it's ECM
2014-07-01T17:45:13 < karlp> I get that, I'm just asking what the use case is that someone wanted that.  If you can't say, that's fine,
2014-07-01T17:45:27 < _franck__> no I can't
2014-07-01T17:46:24 < _franck__> I would need to emulate the pegasus etherent device: http://lxr.free-electrons.com/source/drivers/net/usb/pegasus.c
2014-07-01T17:47:03 < _franck__> not sure what kind of CDC it is.
2014-07-01T17:47:11 < _franck__> That's not my focus for now
2014-07-01T17:50:58 < _franck__> how stable/versatile is the libopencm3 usb stack ?
2014-07-01T17:51:00 < _franck__> looks good
2014-07-01T17:51:23 < _franck__> plus, there is mass storage support in pull request

2014-07-01T17:52:07 < karlp> usb device mode is pretty stable, people seem to like it.
2014-07-01T17:52:17 < Steffanx> Don't forget to look at the license of libopencm3.. it doesn't suite everyones needs ;)
2014-07-01T17:52:39 < karlp> ^^^̂̂  yeah, what he said
2014-07-01T17:52:52 < _franck__> LGPL v3 ? right ?

2014-07-01T17:56:33 < _franck__> ok, now I have my led blinking. Let's try a printf :) (and google how to redirect stdout to my choosen UART)
2014-07-01T17:57:00 < karlp> examples in libopencm3-examples if you do go downthat path
2014-07-01T17:57:52 < _franck__> yeah, I'm on it. My led is blinking with miniblink.hex :)
2014-07-01T17:58:05 < karlp> also, #libopencm3 if you didn't know about it...

2014-07-01T22:56:02 < inca> hey folks, anyone here used emWin or STemWin for GUI building?
2014-07-01T22:58:43 < Tectu_> yes
2014-07-01T22:59:09 < inca> what are your thoughts on it?
2014-07-01T22:59:20 < Tectu_> I don't like it.
2014-07-01T22:59:35 < Tectu_> http://www.emblocks.org/forum/viewtopic.php?f=27&t=415#p2158
2014-07-01T23:00:13 < Tectu_> inca, the code base is horrible, the performance is not that nice and it's crowded as hell.
2014-07-01T23:00:47 < Tectu_> inca, the only thing that I at first liked was the GUI designer, but that thing is far from usable (see the comments later down in the forum thread I just linked). The designer does not even give you something like grids, snap'to'line or basic layouts
2014-07-01T23:02:38 < inca> yeah, I am on a project trying to wrangle a tightly specified couple of UI screens with it. it's taking time
2014-07-01T23:02:54 < inca> what are the best in class software tools for doing this kind of thing commercially?
2014-07-01T23:03:34 < Tectu_> emWin seems to be the market leader, but again, they don't provide any specific tools for that
2014-07-01T23:03:56 < Tectu_> next well known one is uCOS/GUI library, but that is chinese code. That's the thing you get on every ebay board. that is the worst.
2014-07-01T23:04:37 < inca> how many of them have simulators for the UI on desktop?
2014-07-01T23:04:40 < Tectu_> inca, one more thing I didn't like about (ST)emWin: The source is not open, you get a library file and everything is included there. Also not that nice for code as C does not have code sections
2014-07-01T23:05:28 < Tectu_> inca, STemWin does not have a simulator, just the designer that is unusable. About the uC/OS I cannot say anything, but I've never hard of a simulator. uGFX can be compiled as native applications for Windows, Linux and Mac OS-X
2014-07-01T23:05:43 < inca> http://www.segger.com/downloads.html?pid=26
2014-07-01T23:06:00 < inca> simulation on windows via visual studio
2014-07-01T23:06:41 < Tectu_> yes, that is the unusable thing.
2014-07-01T23:07:04 < Tectu_> I ask many people that come to uGFX why they use it and don't go for STemWin and the designer was listed many times
2014-07-01T23:07:07 < inca> seems to work
2014-07-01T23:07:28 < inca> not the code generator
2014-07-01T23:07:56 < inca> write code for the widgets and frames and stuff, get it up on the desktop. it emulates the LCD
2014-07-01T23:09:41 < Tectu_> ah, they have a separate simulator, nice
2014-07-01T23:14:52 < Tectu_> inca, furthermore, uGFX gives more than just a graphic stack
2014-07-01T23:15:43 < Tectu_> inca, it has a built-in (but optinal, you can exclude it so it takes up 0 bytes) file system support which gives the same API across many different file systems etc. Now we also have an audio output layer to give acustic feedback on user interactions etc
2014-07-01T23:15:57 < Tectu_> inca, but as everything in uGFX, all of that is completely optional and can be excluded to zero-size

2014-07-01T23:19:55 < Tectu_> inca, Smd_  here has moved to uGFX after trying emWin ;-)
2014-07-01T23:20:12 < Tectu_> maybe he can leave his own feedback
2014-07-01T23:27:26 < Laurenceb__> does uGFX have a gui creator tool?
2014-07-01T23:27:45 < Tectu_> Laurenceb__, work in progress.
2014-07-01T23:27:58 < Tectu_> Laurenceb__, should be there soon
2014-07-01T23:27:58 < Laurenceb__> ah
2014-07-01T23:28:13 < Tectu_> Laurenceb__, but native "host computer builds" help a lot
2014-07-01T23:28:48 < Laurenceb__> yeah
2014-07-01T23:28:58 < Tectu_> inca, feedback that just came in per mail three minutes ago:    "Nice to hear you're working on the documentation - that's the bit that lets down so many open source projects (and ugfx is a lot better than many already). "
2014-07-01T23:29:24 < inca> Tectu_: do you have plans for (or already do) an LCD emulator for simulating the GUI on the desktop?
2014-07-01T23:30:34 < Tectu_> inca, that already works since ages
2014-07-01T23:31:03 < Tectu_> inca, you can take the uGFX code that runs on your microcontroller and compile it as a native windows, linux or os x application without changing a single line (although you normally do it the other way around)
2014-07-01T23:31:23 < Tectu_> inca, uGFX has a complete OS abstraction layer. hence we can compile native applications for every OS
2014-07-01T23:32:20 < inca> arg... cygwin. I've managed to avoid it so far... =)
2014-07-01T23:32:55 < Tectu_> inca, somebody told me that he compiles uGFX with windows visual studio and therefore the windows compilers without any issue
2014-07-01T23:33:37 < Tectu_> inca, the only reason I made it cygwin so far is because I wanted to get it working quickly and I am not a windows person. I didn't want to spend three months in figuring out how to get VisualStudio to work for doing a 300 picture step-by-step guide then ;-)
2014-07-01T23:33:54 < inca> heh

2014-07-01T23:35:25 < Laurenceb__>  :P
2014-07-01T23:35:32 < Tectu_> inca, and yes, it looks ugly. That is because we have a very very minimalistic default rendering routine. However, each and every widget takes a custom renderer (function pointer) so you can make it bling-bling
2014-07-01T23:35:56 < Tectu_> inca, it should no longer be private

2014-07-02T04:06:49 < __rob> upgrdman, inline function should go in the header entirely
2014-07-02T04:07:19 < upgrdman> oh
2014-07-02T04:07:19 < upgrdman> ok
2014-07-02T04:07:24 < __rob> thats the whole point, the function is inlined where it is used. The only way you can do that is have the definition available for the translation unit
2014-07-02T04:08:01 < __rob> so in each C file, in each place it is used, the code is effectively copied and pasted
2014-07-02T04:08:22 < upgrdman> of course. why didnt i realize that :(
2014-07-02T04:09:10 < upgrdman> guess i thought the linker would copy-n-paste as needed.
2014-07-02T04:09:36 < __rob> well no, if you think about it...
2014-07-02T04:09:58 < __rob> if you had a precompiled object, and the linker wanted to copy and paste the precompiled code for your inline function

2014-07-02T06:04:21 < zyp> I remember looking at that, but I never found something suitable before the design I needed it for was scrapped
2014-07-02T06:13:13 < dongs> LTC has a catalog section of charger + dc/dc

2014-07-02T06:25:54 < dongs> getting closer
2014-07-02T06:26:01 < englishman> well if your device is running off of lipo, it should be able to be powered off of 3.6v no?
2014-07-02T06:26:16 < dongs> but not off 4.35
2014-07-02T06:26:26 < dongs> I onyl need 3.3V

2014-07-02T06:27:04 < englishman> this chip + ldo + lipo is intended use i think
2014-07-02T06:27:19 < dongs> right,m not gonna work. need dc/dc not ldo
2014-07-02T06:27:49 < dongs> bq25015 fail too, only 300mA dc/dc and 500mA charge
2014-07-02T06:28:09 < dongs> whyt the hell TI doenst have a category for these
2014-07-02T06:30:53 < jadew> so I just managed to compile an empty main(), do I have to specify that I want the outputs to be in high impedance mode or is that the default?
2014-07-02T06:31:22 < dongs> usually you wanna set all gpio ports to analog in mode
2014-07-02T06:31:31 < dongs> except the jtag pins (if F2/f3/f4
2014-07-02T06:31:41 < jadew> I noticed some rather lengthy "SystemIinit()" functions, is that really needed?
2014-07-02T06:31:54 < jadew> analog mode being... non pulled up/down high impedance?
2014-07-02T06:32:29 < dongs> GPIO_AIN or whatever the define is
2014-07-02T06:32:35 < dongs> yeah
2014-07-02T06:33:00 < jadew> so what's the default state after reset? unknown?
2014-07-02T06:33:45 < dongs> dunno, its in datasheet/reference manual. i jsut change it in startup to make sure.
2014-07-02T06:33:54 < jadew> I'm only asking because I was expecting them to be in that state by default, yet I see this huge initialization functions that seem to do what the hardware should already do after a hard reset
2014-07-02T06:34:37 < jadew> I actually looked for that info in the datasheet but didn't stumble upon it
2014-07-02T06:34:38 < Thorn> SystemInit() doesn't touch GPIO afaik
2014-07-02T06:34:48 < jadew> well, it touches a lot of crap
2014-07-02T06:35:01 < jadew> I saw GPIO stuff in other places maybe
2014-07-02T06:35:05 < Thorn> it sets up the clock
2014-07-02T06:35:30 < Thorn> which is not easy on high-end microcontrollers
2014-07-02T06:35:31 < jadew> but it looks like it does touches the GPIO

2014-07-02T06:35:40 < dongs> uh no

2014-07-02T06:39:59 < upgrdman> what does cargo cult mean?

2014-07-02T06:40:45 < upgrdman> oh

2014-07-02T07:09:46 < emeb_mac> only NSA is allowed to look
2014-07-02T07:09:57 < johntramp> if I write to the control register CRYP_CR and read back out of it all I get is zero
2014-07-02T07:10:18 < dongs> jadew: did you power it up
2014-07-02T07:10:20 < dongs> err
2014-07-02T07:10:23 < dongs> johntramp: ^
2014-07-02T07:10:31 < dongs> and, is your chip the one with crypto
2014-07-02T07:10:36 < dongs> i.e. 41x and not 40x
2014-07-02T07:10:55 < upgrdman> ya, turn on the clock
2014-07-02T07:11:09 < emeb_mac> spoiler alert
2014-07-02T07:11:11 < upgrdman> any peripheral must have it's clock turned on before you can do anything with it
2014-07-02T07:11:27 < emeb_mac> the embedded equivalent of "did you plug it in?"
2014-07-02T07:11:49 < upgrdman> if your using the register definitions, iirc the only thing you can dick with before turning on the corresponding clock... is RCC, the reset and clock controller :)
2014-07-02T07:13:07 < johntramp> dongs: mine is 407
2014-07-02T07:13:12 < dongs> then you're screwed
2014-07-02T07:13:18 < dongs> only 41x has crypto  i thought?
2014-07-02T07:13:36 < dongs> 417 would be the one.

2014-07-02T07:15:59 < emeb_mac> RNG and CRC yeah
2014-07-02T07:16:00 < johntramp> hmm   so why would the ref manual spec for the 40x line under cryp?
2014-07-02T07:16:24 < johntramp> eg  Number of cycles required to process each 128-bit block

2014-07-02T07:20:23 < upgrdman> dunno
2014-07-02T07:27:07 < johntramp> are STM32F407 and STM32F417 interchangeable?
2014-07-02T07:27:12 < dongs> yes
2014-07-02T07:31:18 < emeb_mac> except for missing peripherals... :P
2014-07-02T07:42:30 < madist> you can ask beaky to write code to emulate the missing peripherals
2014-07-02T07:43:18 < upgrdman> that should be interesting

2014-07-02T14:15:59 < karlp> what's a TDR?
2014-07-02T14:16:52 < karlp> windows only software
2014-07-02T14:18:23 < Cyric> yapp but that is not a stong limitation for me
2014-07-02T14:19:05 < Cyric> http://en.wikipedia.org/wiki/Time-domain_reflectometry
2014-07-02T14:20:25 < Cyric> it a technique that can be used in several ways... for example if you have a loss in a underground cable, by TDR you can understand where your cable is brocken
2014-07-02T14:20:58 < Cyric> it basically check changes in the impedence of the medium
2014-07-02T14:21:07 < Cyric> this is what i understood...
2014-07-02T14:25:21 < __rob> can anyone tell me, just looking at someone elses code for an spi dma transfer, they basically transfer a 5 byte array, while reading anywhere up to 100 bytes into another buffer
2014-07-02T14:25:50 < __rob> will overrunning a buffer with the dma cause a hardfault ever ?
2014-07-02T14:26:09 < __rob> or is it just going to always work, but transfer whatever garbage is after the array
2014-07-02T14:29:53 < __rob> http://codepad.org/cRMopAar
2014-07-02T14:30:00 < __rob> theres the key bits to show what I mean

2014-07-02T14:35:38 < rewolff2> __rob: The DMA transfer seems to be setup with TX the number of bytes to be read.
2014-07-02T14:35:54 < rewolff2> So it WILL transfer whatever-garbage is beyond the header.
2014-07-02T14:36:20 < rewolff2> Many SPI chips, after recieving the "please send  me data" have no use for the incoming bits. So they ignore them.
2014-07-02T14:36:45 < rewolff2> Don't do it like this if you have private encryption keys in memory somewhere....
2014-07-02T14:37:11 < rewolff2> but otherwise, why bother complicating the code when the chip is going to ignore the garbage you send?
2014-07-02T14:38:03 < __rob> yea, fair enough
2014-07-02T14:38:04 < __rob> thanks
2014-07-02T14:39:45 < rewolff2> (and you cant pass "sizeof (readheader)" in there, because then the clocking would stop because there is no data to send. You tell the SPI module to create clocks by giving it data to send).

2014-07-02T15:17:05 < jadew> if it's too low, you can probably find better alternatives and just buy a proper scope

2014-07-02T15:18:35 < jadew> you just need to generate a short pulse and see what you get back

2014-07-02T15:22:38 < dongs> he always has solutions for *everything* even when they're completely not practical
2014-07-02T15:23:01 < jadew> but what I said was true
2014-07-02T15:23:14 < dongs> doenstr mean its practical tho
2014-07-02T15:23:24 < jadew> if the LA in that thing sucks, he can get a better one for $50
2014-07-02T15:23:33 < jadew> and a decent scope for ~ $200
2014-07-02T15:23:48 < jadew> certianly much better than what that thing has to offer

2014-07-02T16:11:54 < Claude> "and a decent scope for ~ $200" , huh ?! did i miss something? are decent scope probes now more expensive than decent scopes ? ;)
2014-07-02T16:12:44 < dongs> i dont think one could use ds1052 and 'decent' in same sentence
2014-07-02T16:13:01 < jadew> depends what bandwidth you're after, but given that he was looking at a toy scope, I think the ds1052 is decent
2014-07-02T16:13:02 < Claude> of course not! who would do that?
2014-07-02T16:14:04 < jadew> have you guys ever used one? it kicks ass compared to some offerings from tek & the like
2014-07-02T16:14:23 < jadew> for the price anyway
2014-07-02T16:15:09 < jadew> to get the same functionality with a brand name, you have to pay above $1500, if not more
2014-07-02T16:15:57 < Cyric> i actually wanted something decent and compact..
2014-07-02T16:16:23 < Claude> lol well i recently bought a rigol ds11xxwhatver (4 channels + sig gen) and no it doesn't kick ass in my opinion. a used tek , lecroy or agilent in the same price range  is still better imo
2014-07-02T16:16:24 < jadew> Cyric, I don't think that tiny box is what you're looking for
2014-07-02T16:16:58 < jadew> Claude, which one?
2014-07-02T16:17:04 < jadew> what model exactly?
2014-07-02T16:17:07 < Claude> 4 channels 100mhz bw
2014-07-02T16:17:12 < Claude> don't know
2014-07-02T16:17:14 < jadew> 1104Z?
2014-07-02T16:17:23 < Claude> was quite cheap around 800euros
2014-07-02T16:17:26 < Claude> yeah that one
2014-07-02T16:17:58 < jadew> that scope has 4 channels and 30 k waveform updates/s
2014-07-02T16:18:04 < jadew> doesn't even compare to some of the tek offerings
2014-07-02T16:18:30 < jadew> tek is currently offering a new scope for about $1300 that has 10k points memory and 2 channels :/
2014-07-02T16:18:44 < jadew> and update rates in the range of the ds1052
2014-07-02T16:18:58 < jadew> it's laughable
2014-07-02T16:19:33 < jadew> the lecroys in the same price range are rebadged signlents
2014-07-02T16:19:49 < jadew> which are complete garbage
2014-07-02T16:20:05 < jadew> while the agilent ones are... OLD RIGOLS

2014-07-02T16:20:59 < Claude> 30k waveform updates? lol i wish that would be true. just switch the sig gen on and change some waveform stuff (freq,phase...) on the siggen. then the scope doesn't respond to anything for several seconds...
2014-07-02T16:21:29 < jadew> Claude, I have the 1104Z as well, I have a proper (external) sig gen

2014-07-02T16:21:38 < jadew> but I guess what you're saying is true
2014-07-02T16:21:49 < jadew> it does feel a bit underpowered when it comes to the CPU
2014-07-02T16:21:58 < jadew> but so are other high end scopes
2014-07-02T16:22:06 < jadew> even the MDO4000 from tek has that issue
2014-07-02T16:22:14 < Claude> not what i expect from a measurment device , on my lecroy i can do fft and all fancy math stuff and i don't see any lag or so. oh the lecroy is 15 years old ;)
2014-07-02T16:22:17 < jadew> switch too much stuff on, it halts
2014-07-02T16:22:50 < jadew> Claude, yeah, the old ds1052 seem more responsive as well
2014-07-02T16:22:58 < jadew> and FFT didn't slow them down
2014-07-02T16:23:11 < jadew> I suppose they had to compromise somewhere, I don't mind it that much
2014-07-02T16:23:43 < Claude> i still hope they ship a new firmware for the ds11 ... because it's quite nice in terms of desk space and display
2014-07-02T16:23:51 < Claude> but the lags suck
2014-07-02T16:23:55 < jadew> I agree
2014-07-02T16:24:09 < jadew> I only noticed the lag when I had math + some measurements on
2014-07-02T16:24:20 < jadew> no lag with FFT tho
2014-07-02T16:24:51 < Claude> necer tried fft on the rigol. but the protocol decoders are nice
2014-07-02T16:24:55 < Claude> never
2014-07-02T16:24:57 < jadew> btw, the update rate shouldn't be affected by the CPU
2014-07-02T16:25:05  * talsit doesn't think he's ever needed fft on his 1102
2014-07-02T16:25:05 < jadew> I'm fairly sure that part is handled in the FPGA
2014-07-02T16:25:28 < jadew> I didn't needed the protocol decoders :P
2014-07-02T16:25:36 < jadew> using FFT quite a lot on the other hand

2014-07-02T16:26:46 < Claude> indeed
2014-07-02T16:27:42 < Claude> ah and one more annoying thing on the rigol , it beeps and freezes when it gets a new dhcp lease :)
2014-07-02T16:27:54 < jadew> didn't notice that
2014-07-02T16:28:13 < jadew> I hate the ammount of time it takes to take a screenshot
2014-07-02T16:28:29 < jadew> sometimes it's better to hit stop and then take the screenshot, rather than do it while it's running
2014-07-02T16:28:45 < jadew> again, an issue the DS1052 didn't have
2014-07-02T16:29:27 < Claude> but well you get what you paid for , and tbh it isn't that for the price :)
2014-07-02T16:29:35 < Claude> that bad...
2014-07-02T16:29:53 < jadew> yeah, it's deffinitely a good compromise
2014-07-02T16:30:14 < jadew> personally, I wanted something like the 2000 series but with 4 channels
2014-07-02T16:30:21 < Claude> it is , not for professional stuff but for hobby/semi pro usage it is great
2014-07-02T16:30:42 < jadew> yeah
2014-07-02T16:33:17 < jadew> Claude, I wonder how the new version is
2014-07-02T16:33:19 < jadew> the one with the LA
2014-07-02T16:33:48 < jadew> I'm not sure if the screen is big enough for that
2014-07-02T16:36:16 < jadew> Claude, I was wondering about the sig gen on the 1104Z, does it have jitter at higher frequencies?

2014-07-02T16:42:26 < dongs> i need to come up with a reason to get the new tek scope+spectum analyzer
2014-07-02T16:42:36 < jadew> dongs, there's none
2014-07-02T16:42:40 < jadew> I think it's a very bad idea
2014-07-02T16:42:51 < dongs> especailly since i have both devices separately already
2014-07-02T16:42:59 < jadew> very expensive and it can only work as one or the other
2014-07-02T16:43:05 < dongs> so it would not be a very big upgrade unless i get 6ghz one
2014-07-02T16:43:17 < dongs> jadew: wat, of course it can do both?
2014-07-02T16:43:24 < jadew> dongs, the MDO3000 can't
2014-07-02T16:43:35 < jadew> it's not really a MDO, it's a MSO or SA
2014-07-02T16:43:40 < jadew> you can't have both at the same time
2014-07-02T16:43:43 < dongs> i was looking at mdo4k anyway.
2014-07-02T16:43:50 < dongs> since i ihave a dpo4k now
2014-07-02T16:43:50 < jadew> ah, that one is cool
2014-07-02T16:44:14 < dongs> maybe MDO4054B-6 or something. but i really cant justify needing it.
2014-07-02T16:44:42 < jadew> well, it's cool :D
2014-07-02T16:44:50 < dongs> definitely.
2014-07-02T16:45:16 < dongs> plus its probably just as haxable as dpo4k, to enable various decoders/options/etc
2014-07-02T16:45:24 < Claude> meh $21k , no thanks need a new car first :)
2014-07-02T16:45:45 < jadew> yeah, I heard they all are
2014-07-02T16:45:55 < dongs> 21k is a pretty shitty car
2014-07-02T16:46:05 < jadew> dongs, depends if it's new or not
2014-07-02T16:46:14 < dongs> why would you buy a non-new car
2014-07-02T16:46:22 < dongs> so you could deal with all the fail of previous owner?
2014-07-02T16:46:51 < jadew> depends on the car / where you're getting it from
2014-07-02T16:47:08 < Claude> yeah but from $21k to a non-shitty car the way is waaaay shorter than from $0 to non-shitty

2014-07-02T16:58:53 < jadew> I'm sure that question was asked in all seriousness before
2014-07-02T16:59:13 < jadew> I was once asked (by a cab driver) if the stars are further away than the moon
2014-07-02T16:59:41 < jadew> we got into that discussion because I was transporting a big box containing a telescope
2014-07-02T17:00:10 < madist> personally, if its too far to hit with a thrown stone, then its all the same distance.

2014-07-02T17:03:25 < edmont> how can i know if a pin has been set after using BSSR?
2014-07-02T17:03:54 < edmont> i mean, imagine it's short-circuited to ground
2014-07-02T17:04:06 < dongs> ODR
2014-07-02T17:04:11 < edmont> should i read ODR or IDR?
2014-07-02T17:04:14 < dongs> ODR.
2014-07-02T17:04:19 < edmont> thx dongs
2014-07-02T17:04:22 < dongs> thats what shows what you set it TO
2014-07-02T17:04:30 < dongs> IDR (if port is input) would show the actual pin state.
2014-07-02T17:05:17 < dongs> fuuuu
2014-07-02T17:05:33 < edmont> but if it's output and is short-circuited, would ODR pin be 0?
2014-07-02T17:05:45 < dongs> no, you'd probably be frying your mcu
2014-07-02T17:05:50 < madist> that is an interesting thought.
2014-07-02T17:06:21 < madist> I will try it on an MSP430. The MSP430 output mosfets are very low current devices. They can be safely short-circuited without damage.

2014-07-02T17:07:38 < edmont> just doing it for the test, for a few instructions
2014-07-02T17:07:39 < madist> edmont: momentary shortcircuits or long term ?
2014-07-02T17:07:51 < edmont> momentary
2014-07-02T17:08:07 < edmont> it allows to check the soldering quality
2014-07-02T17:08:39 < edmont> i do it with unconnected pins

2014-07-02T18:51:02 < emeb> actually bootloader gives up after ~1ms and resets xtal pins
2014-07-02T18:51:04 < zyp> so bootloader doesn't like crystal?
2014-07-02T18:51:09 < zyp> which speed?
2014-07-02T18:51:11 < emeb> that's what I'm thinking
2014-07-02T18:51:19 < emeb> speed is correct - 8MHz
2014-07-02T18:51:30 < emeb> but startup time to solid oscillation is fairly long
2014-07-02T18:51:31 < zyp> hmm, strange
2014-07-02T18:51:50 < zyp> load caps correct?
2014-07-02T18:51:50 < emeb> when not in boot mode, xtal gets to clean signal in ~2ms
2014-07-02T18:52:02 < emeb> yeah - next thing to check.
2014-07-02T18:52:17 < dongs> usb bootloader as in onboard one?
2014-07-02T18:52:19 < emeb> on another board the xtal starts up in < 1ms
2014-07-02T18:52:21 < dongs> or shit you wrote
2014-07-02T18:52:28 < emeb> dongs: STs on-board
2014-07-02T18:52:32 < dongs> oh new board. works on old?
2014-07-02T18:52:37 < emeb> yeah
2014-07-02T18:52:44 < dongs> maybe you put 0.1uF as crystal caps.
2014-07-02T18:52:52 < zyp> the built in one will only start if it finds a working external clock source
2014-07-02T18:53:01 < emeb> yes
2014-07-02T18:53:15 < dongs> are you manually dicking these?
2014-07-02T18:53:20 < zyp> so not being able to start HSE fast enough is a likely culprit

2014-07-02T18:53:36 < emeb> question is why the xtal starts so slowly
2014-07-02T18:54:20 < emeb> the load caps are white ceramic, not brown like the rest of my 0.1uf bypass caps, so that's not it
2014-07-02T18:54:21 < dongs> i did http://i.imgur.com/r4k1RNH.jpg by hand today.
2014-07-02T18:54:22 < dongs> not fun
2014-07-02T18:54:39 < emeb> I ordered 36pf caps... who knows what they really are.
2014-07-02T18:54:48 < dongs> 36pf sounds awfully high
2014-07-02T18:54:56 < emeb> talk to zyp about that. :)
2014-07-02T18:58:03 < perole> speaking of upgrade, any (more or less) out-of-the-box solutions for doing via sd card?
2014-07-02T18:58:03 < zyp> sounds right if the crystal has a C_L of 18pF
2014-07-02T18:58:09 < emeb> ya
2014-07-02T18:58:52 < dongs> perole: not really hard, add fatfs to bootloader, read firmware.bin from card, erase flash, upload.
2014-07-02T18:59:00 < perole> my current 'product' uses usb with the microchip usb stack, which is no longer supported, and is a PITA to maintain
2014-07-02T18:59:08 < dongs> if you re already doing sd in your userspace... youre done

2014-07-02T19:01:51 < perole> with the microchip stuff, I have a bootloader in flash that just jumps to the 'user program' if upgrade condition is not met, if it executes it reflashes the 'user program'
2014-07-02T19:02:16 < perole> so you have to be careful with pointers, where things start etc
2014-07-02T19:02:28 < emeb> pulling caps off changes behavior...
2014-07-02T19:02:31 < perole> same principle with stm32, or do you get some frebies?
2014-07-02T19:02:37 < perole> freebies, my spelling is off today..
2014-07-02T19:02:58 < emeb> xtal starts up fast - IF scope probe is on one of the legs. :P
2014-07-02T19:02:59 < dongs> perole: you have a bootloader in rom that  does uart/usb(on some devices)/some more exotic weird interfaces. to do SD, you ahve to write your own
2014-07-02T19:03:05 < emeb> and then usb enumerates.

2014-07-02T19:15:21 < emeb> as zyp pointed out that doesn't give you the loading value that you might expect
2014-07-02T19:15:42 < emeb> since caps to gnd act like they're in series as the xtal sees them.
2014-07-02T19:16:13 < emeb> actual loading capacitance is 1/2 the value of the caps.
2014-07-02T19:16:41 < dongs> for amazing stability, try connecting xtal GND pads to VCC_PLL
2014-07-02T19:16:50 < dongs> isntead of GND.
2014-07-02T19:18:11 < madis_> if you really care, you should take into account the PCB trace capacitance as well because that's going to be a few pf too.

2014-07-02T19:20:24 < karlp> dongs: that openblt migth be gpl, but at least it's gpl with a clear exception to combining with your final app
2014-07-02T19:20:28 < emeb> so if you're ont sensitive to frequency then it's OK to have lower loading cap value
2014-07-02T19:20:37 < madis_> and then you have funny shit like MSP430's where the datasheet says ESR should not be less than 40 ohms, but when you go to buy a crystal you find that they don't make any with ESR more than 40 ohms.

2014-07-02T20:00:01 < dony> hello are there any books about the stm32f4 which are good for beginners (I'm not talking about the reference manuel or the datasheet of course) that will teach me to program the board?
2014-07-02T20:00:21 < dongs> both of those things will teach youhow to program it
2014-07-02T20:00:25 < Thorn> joseph yiu
2014-07-02T20:00:44 < Thorn> not about "the board" though
2014-07-02T20:01:25 < Thorn> http://www.amazon.com/Definitive-Cortex%C2%AE-M3-Cortex%C2%AE-M4-Processors-Edition/dp/0124080820/ref=dp_ob_title_bk
2014-07-02T20:01:49 < Thorn> there're some recent books for beginners, I haven't seen them
2014-07-02T20:02:18 < dongs> im pretty sure thatbook is overkill
2014-07-02T20:02:19 < dony> dongs: you mean datasheet and reference manual but its really hard to read I mean I've read parts of them but still coudln't understand
2014-07-02T20:02:50 < dony> I'll give them another read
2014-07-02T20:03:20 < Thorn> dongs: latest edition has some tutorial chapters at the end iirc
2014-07-02T20:05:39 < dongs> dony: you should have picked up the nucleo b oards.
2014-07-02T20:05:45 < dongs> tehy program with some arduino-esque shit.
2014-07-02T20:05:52 < dongs> where you dont have to think
2014-07-02T20:05:52 < dony> guess so
2014-07-02T20:06:03 < dongs> tho you can probably just load same firmware on f4disco
2014-07-02T20:06:16 < dony> I want to think :p
2014-07-02T20:07:00 < Laurenceb> is F3 high res timer really high frequency?
2014-07-02T20:07:10 < Laurenceb> or is it really a dithered normal timer?
2014-07-02T20:07:12 < dongs> i think its double sysclk
2014-07-02T20:07:21 < dony> but I have time constraints
2014-07-02T20:07:24 < Laurenceb> but not 4.6Ghz?
2014-07-02T20:07:35 < dongs> no clu.
2014-07-02T20:07:43 < dongs> i remember there was a timer on non_F1 shit that was double sysclk.
2014-07-02T20:07:50 < dongs> thats all i know
2014-07-02T20:07:54 < Laurenceb> they claim dedicated pll
2014-07-02T20:08:01 < Laurenceb> for up to 144*32mhz
2014-07-02T20:08:10 < dongs> no shit.
2014-07-02T20:08:27 < dongs> you can send shit to the moon with that.

2014-07-02T20:17:05 < Laurenceb__> oh
2014-07-02T20:17:43 < Thorn> how can you have cycle-accurate delays with wait states, caches, bus arbitration, nop folding and shit
2014-07-02T20:17:44 < Simon--> dithered normal timer?
2014-07-02T20:17:51 < Simon--> at least the f3 actually has 1 32-bit timer ;)
2014-07-02T20:18:47 < Laurenceb__> i think its a dithered normal timer
2014-07-02T20:18:58 < Laurenceb__> i.e. useless
2014-07-02T20:19:08 < Laurenceb__> you can dither any stm timer using dma
2014-07-02T20:19:30 < Simon--> what does that mean...you can't pwm capture to the cycle?
2014-07-02T20:19:42 < Laurenceb__> yeah
2014-07-02T20:19:59 < Laurenceb__> so useless for anything where you might actually need 216ps resolution

2014-07-02T20:36:04 < emeb> Laurenceb_ sounds like they're splitting the clock cycle using DPLL techniques
2014-07-02T20:36:34 < emeb> so there are multiple phases of the low-speed clock, generated using synchronized delay rings or something.

2014-07-03T07:30:00 < dongs> The story goes that Young heard his songs on a CD for the first time in 1982, around the time the discs were first coming to market. He was disappointed at how bad they sounded; he didn't hear the plainspoken folk songs he'd played, but something much flatter and more condensed. The sound lacked the soul of his music.
2014-07-03T07:34:37 < dongs> "It's starting to sound like an amazing, warm, dynamic analog recording," says a beaming Chris Robinson, the Black Crowes's frontman, at a concert.
2014-07-03T07:34:40 < dongs> loool
2014-07-03T07:34:53 < dongs> "It's vinyl quality," says a young music fan.

2014-07-03T08:31:43 < gnomad> Many early CDs really did sound pretty awful.
2014-07-03T08:41:09 < dongs> emeb_mac: im looking at that CS dac datasheet, and 'power consumption' stuff is really low, like 2-3mA max,, but it has some mWrms metric, wtf is that?
2014-07-03T08:41:21 < dongs> how do I figure out ie how much its gonna draw on 1.8V or something
2014-07-03T08:42:25 < emeb_mac> this on the CS43L22 part?
2014-07-03T08:43:11 < dongs> ya
2014-07-03T08:43:20 < emeb_mac> checking...
2014-07-03T08:43:21 < dongs> 'there's shit on page 19
2014-07-03T08:43:24 < dongs> power consumption
2014-07-03T08:43:34 < dongs> but hte numbers are too small to make sense, only drawing like 4mA while playing to speaker???
2014-07-03T08:44:40 < rewolff2> Power consumption is usually quoted without the "obvious" power draw by the "load".
2014-07-03T08:45:07 < rewolff2> An STM32 (staying on topic) will draw say 5mA if you clock is slowly and carefully.
2014-07-03T08:45:18 < rewolff2> but you can easily load one or two outputs at 10mA each.
2014-07-03T08:47:45 < gnomad> do they specify a load impedance?
2014-07-03T08:48:41 < emeb_mac> dongs: what rewolff2 said - figure out what the max speaker output power is based on the supply voltage, then convert that to current and add to the current shown on pg19
2014-07-03T08:49:19 < dongs> 1.8V is only driving headphonese
2014-07-03T08:49:28 < dongs> speakers are from 5V, which I dont really  care about calcualting current of
2014-07-03T08:49:54 < dongs> anyway, ok, i got it
2014-07-03T08:49:58 < dongs> so its not included.

2014-07-03T08:50:23 < emeb_mac> so for 5V, max power to speakers is quoted at 2x1.0W - so( 200mA X 5v) x 2 = 400mA from 5V supply

2014-07-03T08:53:16 < rewolff2> Is it class D? Efficiency also counts. For class D count about 80-90% of power drawn ends up in the speaker, for class AB or thereabout I usually count on 50%, but It might be 70% (max).
2014-07-03T08:54:50 < dongs> headphone part in that thing is "ground-centered amp" wahtever the fuck that is.

Memorex Music 80 minutes is very nice  Taiyo Yuden 700 MB are close, the Mitsui and BASF are in there, Apogees has a nice width but lacks warmth.

2014-07-03T16:43:06 < Cyric> i think with usart is easier.. if i initialize USART1 and i only use TX and RX, can i reuse all the other pins of the interface for other purposes (like RTs, CTS, etc)

2014-07-03T17:28:21 < Tectu_> AndreeeCZ, are you using the stdperiph lib?
2014-07-03T17:34:33 < AndreeeCZ> Tectu_, for the usbd/otg yes
2014-07-03T17:34:41 < AndreeeCZ> for setting the pins im using libopencm3
2014-07-03T17:35:31 < AndreeeCZ> the interrupt handler (otg_hs_isr()) is in the interrupt vectors, defined correctly and corresponds to the same thing as the one in stdlibs
2014-07-03T17:36:23 < Thorn> so which vector table are you using? libopencm3 or stdperiph?
2014-07-03T17:36:34 < AndreeeCZ> Thorn, libopencm3
2014-07-03T17:37:35 < Thorn> are you sure the stdperiph otg handler is being called?
2014-07-03T17:39:35 < AndreeeCZ> the interrupt handler?
2014-07-03T17:39:46 < Thorn> yes
2014-07-03T17:40:01 < AndreeeCZ> im using the libopencm3 handler
2014-07-03T17:40:28 < Thorn> you said you're using  stdperiph for otg
2014-07-03T17:41:13 < Tectu_> AndreeeCZ, you can't use both interrupt handlers at the same time
2014-07-03T17:41:22 < AndreeeCZ> for the setup and processing yes. For the interrupt handler libopencm3
2014-07-03T17:41:25 < Thorn> or both drivers
2014-07-03T17:41:38 < Thorn> and why do you think that would work?
2014-07-03T17:42:31 < AndreeeCZ> this is how im handling the interrupt
2014-07-03T17:42:32 < AndreeeCZ> http://pastie.org/9350617
2014-07-03T17:42:51 < AndreeeCZ> and this is how im enabling that interrupt nvic_enable_irq(NVIC_OTG_HS_IRQ);
2014-07-03T17:43:06 < AndreeeCZ> that's libopencm3
2014-07-03T17:43:26 < AndreeeCZ> but all the usb-related libs are from st
2014-07-03T17:43:41 < Thorn> ok I see, that looks good
2014-07-03T17:43:53 < Tectu_> that should work indeed
2014-07-03T17:44:06 < Thorn> you can set a breakpoint or turn on a led there to see if it's actually called
2014-07-03T17:44:24 < AndreeeCZ> Thorn, that's what im trying to do. And it isn't.
2014-07-03T17:44:49 < AndreeeCZ> im setting up the usb as from stlibs like so USBH_Init(&USB_OTG_Core_dev, USB_OTG_FS_CORE_ID, &USB_Host, &MIDI_cb, &USR_Callbacks);
2014-07-03T17:45:10 < AndreeeCZ> as is in various st examples and lots of projects on github
2014-07-03T17:45:40 < AndreeeCZ> the vbus is setup correctly and is powering up the device
2014-07-03T17:45:46 < AndreeeCZ> but the interrupt doesnt get called
2014-07-03T17:48:22 < AndreeeCZ> this is the setup for the pins: http://pastie.org/9350630
2014-07-03T17:48:39 < AndreeeCZ> all the functions get called.

2014-07-04T02:15:30 < Tectu_> emeb, nothing special. Currently there's just high level API for audio in and output. No mixer nor other fancy stuff. However, stuff like mixer, FFT and other basic crap are under development.
2014-07-04T02:15:39 < Laurenceb> karlp: huh?
2014-07-04T02:15:48 < Tectu_> emeb, but you can always just output raw audio data :P

2014-07-04T02:16:38 < Laurenceb> the keywords are epic lulz
2014-07-04T02:17:02 < Laurenceb> Tectu: so how do you output the audio?
2014-07-04T02:17:11 < Tectu_> emeb, the philosophy of uGFX is providing common API that is the same accross all targets put having the most optimal implementation for each. Hence we don't provide you with a HAL
2014-07-04T02:18:00 < Tectu_> emeb, however, we provide different drivers, so all you have to do is implementing the actual HAL interface
2014-07-04T02:18:18 < emeb> so the architecture-dependent code must be provided by the implementor
2014-07-04T02:18:24 < Tectu_> Laurenceb, if you happen to be nasty, you can go with   gaudioPlayFile("MyAudio.mp3);
2014-07-04T02:18:29 < Tectu_> emeb, yes
2014-07-04T02:18:34 < Laurenceb> yeah but where does it go?
2014-07-04T02:18:51 < Tectu_> emeb, of course we provide both empty templates and already implemented "examples" that can be used
2014-07-04T02:19:15 < Tectu_> Laurenceb, as I said - different driver backends. There are working drivers for the PWM output on your MCU, external DACs with I2S interface or even a whole external codec.
2014-07-04T02:19:25 < Laurenceb> ah
2014-07-04T02:19:35 < Laurenceb> what about mp3 decoding?!
2014-07-04T02:19:59 < Tectu_> Laurenceb, we have the drivers for all the methos mentioned above, all you have to do is supplying the board file (or using an existing one)
2014-07-04T02:21:05 < Tectu_> Laurenceb, the module is in an early stage. There's currently no built-in software based MP3 decoder. However, you can output MP3 using an external codec (which I am currently doing in one of my private projects)
2014-07-04T02:21:20 < Tectu_> Personally I use the VS1053 right now

2014-07-04T03:02:26 < emeb> what'cha got?
2014-07-04T03:03:32 < dongs> duno catched parts of the audio chat
2014-07-04T03:05:44 < emeb> dongs: you ever used the SDIO on the F10x parts?
2014-07-04T03:06:07 < emeb> buddy of mine tried, couldn't get it to work. gave up and fell back to using SPI
2014-07-04T03:06:21 < dongs> never did anything with > 48pin F1 so no
2014-07-04T03:06:26 < dongs> i know a guy that did tho.. i think it worked
2014-07-04T03:06:28 < dongs> lemem chec sores
2014-07-04T03:07:40 < dongs> lorf
2014-07-04T03:07:43 < dongs> nope he also used SPI
2014-07-04T03:07:48 < emeb> heh
2014-07-04T03:08:09 < emeb> SDIO on F4xx seems OK - got it working w/o drama
2014-07-04T03:08:42 < dongs> man tehse guys keep piling up more and more shit on this project im doing
2014-07-04T03:08:57 < dongs> started off with: our current shit draws too much current, plz replace with less retarded solution
2014-07-04T03:09:02 < dongs> week later: lets add  this and this and that nad this
2014-07-04T03:09:07 < emeb> typical
2014-07-04T03:09:11 < dongs> (by the time its done, it'll probly draw just as much
2014-07-04T03:09:11 < emeb> feature-creep

2014-07-04T03:10:05 < emeb> and make it red
2014-07-04T03:10:22 < varesa> I tend to feature creep my hw projects to the point I don't have the time or skills to complete them :p
2014-07-04T03:10:33 < dony> can anybody explain to me what open drain is?
2014-07-04T03:10:57 < emeb> n-channel mosfet w/ source to gnd, gate to driving signal, drain floating.
2014-07-04T03:11:20 < emeb> when gate gets signal, fet conducts drain to source, effectively pulling down.
2014-07-04T03:11:54 < emeb> put a resistor on drain to any higher voltage & you get signal that pulls up when gate is off, down when gate is on.
2014-07-04T03:12:12 < dony> are you talking to me emeb cuz I don't understand
2014-07-04T03:12:36 < varesa> dony: simply put switch that has two states: floating and connected to ground
2014-07-04T03:12:39 < dongs> gate signal turn on. all  your qubits are belong to us

2014-07-04T03:14:31 < dongs> hm, 2 designs with this chip and neither has ESD protection diodes. i guess i'll ignore them too.
2014-07-04T03:14:52 < emeb> esd on which pins?
2014-07-04T03:14:59 < dongs> input diff lanes
2014-07-04T03:15:03 < dony> I'm not a troll
2014-07-04T03:15:28 < dongs> datasheet says "put them if you want, just make sure its < 1pF capacitance".

2014-07-04T06:15:54 < upgrdman> shit. fixed it. damn lcd, sharing the PA13/PA14 SWD lines, wouldn't quite release those line when under reset. wonder why this is only now a problem. worked fine for days
2014-07-04T06:16:14 < dongs> lolwut
2014-07-04T06:16:21 < dongs> you have LCD on swd/sclk?
2014-07-04T06:16:32 < upgrdman> suppose i could add a pull down to the lcd's reset line
2014-07-04T06:16:41 < dongs> or the useless shit like jtdi/tms
2014-07-04T06:16:42 < upgrdman> ya. needed the gpio, hence connect-under-reset
2014-07-04T06:16:47 < dongs> har
2014-07-04T06:16:50 < dongs> so hwo do you debug
2014-07-04T06:16:56 < upgrdman> printf to lcd :)
2014-07-04T06:17:00 < dongs> fail.
2014-07-04T06:17:05 < englishman> avr style
2014-07-04T06:17:32 < upgrdman> if i really need to debug i can pull those lines from the lcd and do proper swd debugging
2014-07-04T06:18:07 < upgrdman> it would be nice is stm would put an entire gpio port on a side side of the chip...
2014-07-04T06:18:11 < upgrdman> *a single side
2014-07-04T06:25:29 < dongs> pffffffffffffffffffty

2014-07-04T06:26:41 < upgrdman> well i'm just playing around. so far i have only had one project where i needed to make more than one of the same pcb.
2014-07-04T06:26:56 < upgrdman> not worth the time or money to hire someone, even in china, to make my pcb's.
2014-07-04T06:27:40 < upgrdman> i still don't see why stm would even want to have the pins for one port spread out on all four sides.
2014-07-04T06:27:53 < upgrdman> even it's for AFs, they could just have the AF's on different pins
2014-07-04T06:28:09 < dongs> you could always use bitbanding if you are really that worried about gpio update speed..
2014-07-04T06:28:23 < dongs> oh, F0 probably no bitbands tehre
2014-07-04T06:28:24 < upgrdman> no. f0 doesn't have bit banding :( i checked
2014-07-04T06:28:27 < dongs> lewl
2014-07-04T06:28:38 < dongs> much fail
2014-07-04T06:28:50 < upgrdman> even so, one write to a port is faster than 16 bit band writes

2014-07-04T06:45:40 < emeb_mac> so, looks like you can set up a common sample rate of 37.5kHz between the SDADC and I2S on an F373
2014-07-04T06:46:17 < dongs> o yea?
2014-07-04T06:46:36 < dongs> well, thats a far cry from 192kHz that you need in order to have even a remote chance of succeeding on a dickstarter
2014-07-04T06:46:56 < dongs> my next audiophile gadget will feature 256kHz/32bit sampling rate

2014-07-04T07:39:14 < dongs> no its just oled or some serial one
2014-07-04T07:39:18 < dongs> it doesnt matter, the 'core' code is asme
2014-07-04T07:40:26 < upgrdman> that file almost looks less maintainable than the code that comes with some chinese ebay lcd's.
2014-07-04T07:43:32 < upgrdman> my lcd.c is <400 lines, and with my printf, <600 total lines
2014-07-04T07:43:55 < dongs> why didnt you make printf like line[2]  = '0' + v  / 100000000 - (v/1000000000) * 10;

2014-07-04T09:19:28 < upgrdman> so this color lcd i've got... i'm powering my f0 and lcd through my st-linkV2. i have a toggle switch on the 3v rail, so i can power off the target. if i use that to power off my target, the lcd seems to retain the pixel buffer, indefinitely. if i physically unplug my st-linkV2's usb cable, then plug it back in, the lcd pixel buffer contains random junk as expected. why does only disconnecting +3V not have the same affect?
2014-07-04T09:25:50 < GargantuaSauce> could the stlink still be holding the swd pins high, so the lcd is getting just a little current through the f0's clamp diodes?

2014-07-04T18:21:48 < dongs> right
2014-07-04T18:22:17 < dongs> i left gnd plane as gnd since I'm not planning to put any traces there, but i turned L3 (PWR) into signal
2014-07-04T18:22:47 < dongs> which i couldnt figure out how to do without adding new layer and deleting plane

2014-07-05T15:12:29 < __rob> so I've got a pulse thats 200ns long duty cycle, looking on the scope. Is this short enough that the isr wouldn't have even serviced the first pulse
2014-07-05T15:12:33 < __rob> before the low edge ?
2014-07-05T15:12:49 < __rob> *falling edge
2014-07-05T15:13:10 < __rob> or rather serviced the rising edge interrupt, before the falling edge comes

2014-07-05T19:08:28 < Evidlo> Yes, libopencm3
2014-07-05T19:09:33 < Steffanx> if you want it to print to gdb/openocd you want the semihost example. There is one for L1 you can probably adapt

2014-07-05T19:34:46 < Steffanx> what difference, you mean between the examples Evidlo?
2014-07-05T19:36:08 < Evidlo> Steffanx: The part I need to modify to get it working on an F4
2014-07-05T19:37:47 < sanity93> Is there binary compatibility between Cortex-M devices. Can code run on either (With the exception of device specific hardware)?  eg. SAM3X8E and STM32F103VET6.
2014-07-05T19:41:36 < Steffanx> if you're goal is to get print some data to openocd/gdb then all you need is the semihosting stuff. No gpio etc.
2014-07-05T19:42:31 < Steffanx> Evidlo, are you sure you need that now?
2014-07-05T19:44:44 < Evidlo> I think be able to print stuff is important, yes
2014-07-05T19:44:54 < Evidlo> How else am I to debug?
2014-07-05T19:45:39 < Steffanx> gdb step.. print variables using gdb etc.?
2014-07-05T19:54:06 < Evidlo> All the info I'm finding on setting breakpoints pertains to eclipse

2014-07-05T19:56:49 < Steffanx> it's "just" gdb not?
2014-07-05T19:58:21 < Evidlo> If arm-none-eabi-gdb is gdb, then yes.
2014-07-05T19:59:25 < Steffanx> yes it is
2014-07-05T20:01:38 < Evidlo> Ah, I have a breakpoint set now

2014-07-05T20:33:08 < Evidlo> Steffanx: Any idea why gpio_read isn't recognized as a function?  It's listed in the docs

2014-07-05T20:34:17 < Laurenceb__> sellout
2014-07-05T20:35:31 < Steffanx> sure its gpio_read and not gpio_port_read or gpio_get Evidlo ?
2014-07-05T20:35:49 < Steffanx> also try #libopencm3 they know all about it

2014-07-05T20:37:10 < Steffanx> blame the libopencm3 guys for being inconsistent...
2014-07-05T20:37:28 < Evidlo> Guess I should've checked the url
2014-07-05T20:37:57 < Steffanx> or maybe its not inconsistent..
2014-07-05T20:46:00 < Evidlo> Steffanx: I don't think I'm using breakpoints right.  I load the elf, then the symbols file with 'file', then I set the breakpoint on line 75, but it's telling me that there's no line 75 in the current file.

2014-07-06T02:04:21 < Tectu_> you either build your railgun before 18 or never

2014-07-06T02:13:35 < Evidlo> I can't set any breakpoints.  It keeps saying the line doesn't exist
2014-07-06T02:13:53 < Tectu_> Evidlo, GDB works fine for me for all STM32 that I ever used
2014-07-06T02:13:57 < upgrdman> you doing something like "break main.c:39" ?
2014-07-06T02:14:36 < zyp> Evidlo, remember that you're not executing source, you're executing optimized assembly, which may or may not look exactly like the source
2014-07-06T02:14:39 < upgrdman> here's my setup:
2014-07-06T02:14:41 < upgrdman> https://github.com/farrellf/stm32f0-empty-project/blob/master/config_gdb.cfg
2014-07-06T02:15:03 < zyp> Evidlo, and then you need to have debug symbols in your elf
2014-07-06T02:15:24 < zyp> remember to have some variant of -g in your cflags
2014-07-06T02:15:29 < zyp> -ggdb3 is good
2014-07-06T02:15:31 < Tectu_> -ggdb will do

2014-07-06T02:15:36 < Tectu_> dafuq is 3 ?
2014-07-06T02:15:49 < zyp> includes macros as well, IIRC
2014-07-06T02:16:59 < Evidlo> will load file.elf automatically load the symbols?
2014-07-06T02:18:05 < zyp> no
2014-07-06T02:18:19 < zyp> use «file file.elf» then followed by «load» without arguments

2014-07-06T02:23:42 < Evidlo> So file takes care of the symbols?  I see it mention them after a 'file'
2014-07-06T02:23:58 < zyp> provided there are any symbols in the .elf, yes
2014-07-06T02:25:47 < Evidlo> It's still telling me line 75 doesn't exist: http://www.rafb.me/results/rB3Nfi86.html

2014-07-06T02:28:13 < zyp> so that means that either there is no code in the file corresponding to line 75 or there are no debug symbols at all in it
2014-07-06T02:28:23 < zyp> 01:15:03 < zyp> Evidlo, and then you need to have debug symbols in your elf
2014-07-06T02:28:23 < zyp> 01:15:24 < zyp> remember to have some variant of -g in your cflags
2014-07-06T02:28:23 < zyp> 01:15:28 < zyp> -ggdb3 is good
2014-07-06T02:28:27 < zyp> did you get that part?

2014-07-06T02:30:10 < englishman> Tectu_: ok :)
2014-07-06T02:30:15 < Evidlo> As well as other stuff
2014-07-06T02:30:59 < zyp> ok, then there's probably just that there are no instructions in your file that corresponds exactly to line 75

2014-07-06T02:32:16 < zyp> of course there are no instructions produced for a blank line

2014-07-06T02:33:39 < Evidlo> So I assume dprintf is a form of a breakpoint
2014-07-06T02:34:15 < zyp> yes
2014-07-06T02:34:30 < zyp> it will break, print and continue
2014-07-06T02:34:45 < zyp> but read this again:
2014-07-06T02:34:45 < zyp> 01:14:36 < zyp> Evidlo, remember that you're not executing source, you're executing optimized assembly, which may or may not look exactly like the source
2014-07-06T02:34:47 < Evidlo> What's the tracepoint called that does the same thing as breakpoint, but after the line?

2014-07-06T02:35:43 < zyp> the optimizations may shuffle around instructions and mix up the order stuff happens in, as long as the result remains the same
2014-07-06T02:36:15 < zyp> personally I prefer just reading the disassembly of the function and debugging that instead, since that's what actually executes
2014-07-06T02:39:00 < Evidlo> zyp: The program doesn't seem to work when I use 'file', only 'load'

2014-07-06T15:42:16 < dony> hello I got my bluetooth moduel for the stm32 and I want to know is it possible to send commands to it from my stm32 or does it require extra hardware , software? usually do they require any?
2014-07-06T15:44:54 < qyx_> they are usually controlled using AT commands (simple text messages) and connected using uart/usart on stm32
2014-07-06T15:45:12 < dony> qyx_: so they are controlled directly from the stm32?
2014-07-06T15:45:22 < qyx_> it is written in your BT module datasheet/specs
2014-07-06T15:46:02 < qyx_> yes, they are, shouldn't they be?
2014-07-06T15:46:18 < dony> I think so
2014-07-06T15:47:22 < zyp> how the fuck would anybody be able to answer your question when you haven't even mentioned what kind of bluetooth module you have?
2014-07-06T15:47:25 < __rob> dony _ it will be uart, spi or i2c most likely
2014-07-06T15:47:45 < dony> __rob: its usart

2014-07-06T18:00:18 < Thorn> sure
2014-07-06T18:00:23 < jpa-> using a debugger, yes
2014-07-06T18:00:42 < jpa-> (there is also some ST tool that monitors variables without stopping the program, but i haven't tried that one)
2014-07-06T18:01:12 < dongs> that one is java
2014-07-06T18:02:00 < jpa-> i expect it is shit in also other ways
2014-07-06T18:02:19 < dongs> i think it uses some GNU tools
2014-07-06T18:02:21 < dongs> to load .elf
2014-07-06T18:02:27 < dongs> and gives you a "all epxorted variables' type thing

2014-07-06T18:03:13 < jpa-> in most cases, a debugger is much more useful
2014-07-06T18:03:42 < dony> jpa-: so the emblocks debugger can give me the value of a variable?
2014-07-06T18:04:01 < jpa-> never used it, but if it works with stm32 it definitely should
2014-07-06T18:04:19 < dony> I'm guessing it gives it in binary right?
2014-07-06T18:04:43 < dony> :p
2014-07-06T18:06:26 < qyx_> whats the definition of "binary value"?

2014-07-06T18:07:32 < englishman> its a value that's in binary

2014-07-06T18:52:33 < Thorn> set a breakpoint in it, print a message to uart, turn on a led, launch missiles etc.
2014-07-06T18:53:04 < dony> well say I set a message to uart
2014-07-06T18:53:07 < dony> how can I read ?

2014-07-06T18:58:02 < dony> Nevermind
2014-07-06T18:58:27 < dony> but If I'm putting a breakpoint at a function and the debugger is not stopping at that breakpoint wat does that mean?
2014-07-06T18:59:25 < Thorn> unfavorable phase of the moon
2014-07-06T18:59:36 < Thorn> try to answer this question yourself.
2014-07-06T18:59:37 < jpa-> usually it would mean that it is not going to that function :)
2014-07-06T18:59:53 < dony> jpa-: Well that shouldn't happen
2014-07-06T19:00:01 < dony> I mean the function is in main
2014-07-06T19:00:15 < dony> why the hell wouldn't it run
2014-07-06T19:00:20 < jpa-> then your debugger is broken

2014-07-06T19:01:21 < dony> I mean I'm putting the a breakpoint at a part of the function definition it shouldn't stop at that part
2014-07-06T19:01:24 < dony> jpa-: I'm hoping
2014-07-06T19:03:44 < Thorn> are you compiling with optimization off? is the breakpoint at an executable line of code?
2014-07-06T19:04:26 < dony> I don't know about optimization
2014-07-06T19:04:42 < dony> the breakpoint is in a function definition
2014-07-06T19:05:06 < rewolff2> Dony, start out with break main, reset the cpu, and let it run (continue).
2014-07-06T19:05:10 < rewolff2> See if it breaks on main.
2014-07-06T19:05:24 < rewolff2> If that happens, you know your debugger seems to be working.
2014-07-06T19:06:23 < dony> rewolff1: I don't know what you mean?

2014-07-06T19:14:50 < rewolff2> Good. Now set the breakpoint before you start the program. Leave the breakpoint at "main () " hit the reset (or whatever you do to restart the CPU) again, and continue when it hits main.
2014-07-06T19:15:07 < rewolff2> If it hits the other breakpoint, it will stop there, if not, it is not getting there.
2014-07-06T19:15:22 < rewolff2> On my debugger I can hit "control-c" and  see where it is.
2014-07-06T19:15:41 < rewolff2> Usually in such a case, it happens to be that it's waiting for something in one of the initialization routines.
2014-07-06T19:16:22 < rewolff2> For example, when I first started using USB, it turns out that I have not connected "VBUS" to the appropriate pin on the CPU.
2014-07-06T19:16:50 < rewolff2> So the USB initialization code would wait for the USB module to report "ready" which didn't happen because it didn't see "vbus".
2014-07-06T19:17:44 < rewolff2> (IRC system question: Do you see me as "rewolff1"? out here I seem to be 'speaking' as: "rewolff2"..... .

2014-07-06T19:21:19 < Thorn> how do you calculate all these A B C Q R matrices for the Kalman filter? (system matrix, control, observation matrix, noise covariances)
2014-07-06T19:21:35 < Thorn> are they found experimentally?
2014-07-06T19:22:05 < Laurenceb__> they are guessed
2014-07-06T19:22:13 < Laurenceb__> until it works best :P
2014-07-06T19:22:50 < Thorn> OK I'm gonna start with identity matrices *CRASH*
2014-07-06T19:23:03 < Laurenceb__> usual approach is to start with theoretical values then tweak until it actually works
2014-07-06T19:23:41 < Laurenceb__> mismodelling and stuff means the best match matrices will differ from theory

2014-07-06T21:08:41 < dony> why is that?
2014-07-06T21:13:52 < dony> I'm talking about this USART2->SR

2014-07-06T21:46:15 < dony> hello can anybody help me
2014-07-06T21:46:16 < dony> ?
2014-07-06T21:46:31 < Rickta59> best if you just ask
2014-07-06T21:46:49 < Rickta59> if someone can help you they will
2014-07-06T21:55:02 < dony> weLL after I'm sending data to the bluetooth module the status registery (I thhink thats what it is called) is not becoming empty why is that?
2014-07-06T21:55:44 < gxti> what does 'becoming empty' mean specifically
2014-07-06T21:57:18 < dony> I'm talking about USART2->SR shouldn't it be cleared after sending the data to the module?
2014-07-06T21:57:21 < dony> gxti:
2014-07-06T21:57:23 < dony> ?
2014-07-06T21:57:49 < gxti> no
2014-07-06T21:57:57 < dony> ohh what should happen?
2014-07-06T21:57:57 < gxti> it's a status register, it's never completely 'cleared'
2014-07-06T21:58:33 < dony> yes well in the code its USART2->SR & 0x00000040 I don't know why I tried to understand but I still don't gxti
2014-07-06T22:00:42 < dony> I read it from this tutorial http://eliaselectronics.com/stm32f4-tutorials/stm32f4-usart-tutorial/

2014-07-06T22:04:11 < gxti> and what do you think that might be doing?
2014-07-06T22:05:28 < dony> I think it checks if there is a stored character in SR?do you think so ? because I'm sending characters via USART2 to the bluetooth module, those characters will constitute a string which is a command to the bluetooth module
2014-07-06T22:09:33 < __rob> its checking if the 7th bit is set in the SR register of the usart 2
2014-07-06T22:09:48 < __rob> look at your datasheet and see what that bit is, then you will know what that statement means
2014-07-06T22:10:33 < __rob> in your url you pasted it even says "// wait until data register is empty"

2014-07-06T22:16:32 < dony> __rob: I guess its the TXE register
2014-07-06T22:17:00 < __rob> yea, so it waits untill TX is empty
2014-07-06T22:17:02 < __rob> before filling it again
2014-07-06T22:17:06 < __rob> and seding the next character
2014-07-06T22:17:18 < dony> THat means that data is not being transfered to the Bluetooth module
2014-07-06T22:17:22 < dony> why could that be?
2014-07-06T22:17:37 < __rob> no.. it means it is being transfered, if that register is emptying...
2014-07-06T22:17:42 < __rob> read the datasheet on how the usart works
2014-07-06T22:18:17 < __rob> you put a character in, the hardware writes it for you to the USART pins on ur mcu, then it notifys you thats its done, by setting TXE
2014-07-06T22:18:45 < dony> but __rob in my code Its not emptying cuz when its checking to see if txe is set the code is freezing (as in not doing anything)
2014-07-06T22:19:34 < dony> i.e TXE is not getting set
2014-07-06T22:19:41 < dony> so its not tranmitting right?
2014-07-06T22:19:50 < __rob> enabled the USART clocks ?
2014-07-06T22:19:55 < __rob> checked you've set that up right ?
2014-07-06T22:20:49 < dony> Yes I have
2014-07-06T22:21:11 < dony> its the same as the code that I sent  in the link
2014-07-06T22:21:39 < gxti> that wouldn't be very good then, because the tutorial uses USART1.
2014-07-06T22:22:03 < dony> well no I changed those of course
2014-07-06T22:22:05 < dony> gxti:
2014-07-06T22:22:42 < dony> except for one :/
2014-07-06T22:22:47 < dony> guess that was it

2014-07-06T22:42:57 < dony> if you want to check them please tell me
2014-07-06T22:43:13 < __rob> for a start your interrupt handler is checking USART1 still....
2014-07-06T22:45:12 < dony> i see
2014-07-06T22:47:16 < dony> it is still freezing something weird is happening when the debugger is reaching USART_puts all of a sudden a value is going from false to true USART2->SR & 00000040 is going from true to false
2014-07-06T22:48:22 < __rob> thats correct ?
2014-07-06T22:49:06 < __rob> as you send the next char, TX is no longer empty, until its sent
2014-07-06T22:49:23 < __rob> then its empty, the while loop ends, the next character gets sent
2014-07-06T22:49:34 < __rob> untill *s is the null terminator
2014-07-06T22:51:44 < dony> __rob: but its staying frozen also it hasn't sent any char yet this freezing happens when The debugger goes into USART_puts(USART2, "SET RESET") thats not supposed to happen
2014-07-06T22:52:15 < dony> its staying frozen for a long time I'm sure it would barely take a second for the char to be received on the bluetooth's end

2014-07-07T02:11:59 < dongs> do you WANT or do you HAVE to.
2014-07-07T02:12:20 < eclipnew> I want
2014-07-07T02:12:46 < dongs> what modern mcu is arm926 in 2014
2014-07-07T02:13:15 < Steffanx> if you know how to make gcc do it, it should be pretty straight forwards to make eclipse do it
2014-07-07T02:13:20 < eclipnew> But I cannot find much info about setting up a toolchain for it so I figured a good place to start is here
2014-07-07T02:13:50 < eclipnew> I'm also novice to gcc
2014-07-07T02:13:52 < Steffanx> the stm32 tutorials show you how to do it for stm32...
2014-07-07T02:14:26 < Steffanx> i dont think many here use eclipse
2014-07-07T02:14:28 < eclipnew> There are many versions of gcc and it's a bit confusing which to choose
2014-07-07T02:14:50 < dongs> steffanx only uses EM::Blocks
2014-07-07T02:14:53 < dongs> with arduino lpugin
2014-07-07T02:14:59 < emeb> haha
2014-07-07T02:15:09 < eclipnew> What do most people use here?
2014-07-07T02:15:31 < dongs> windows 8 pro

2014-07-07T02:20:15 < eclipnew> dongs: I intend to use i.mx28
2014-07-07T02:20:29 < dongs> a poor choice
2014-07-07T02:20:35 < eclipnew> Why so?
2014-07-07T02:21:01 < dongs> its only useful for (slowly) running lunix.
2014-07-07T02:21:18 < dongs> forget trying to develop on it bare metal
2014-07-07T02:21:46 < eclipnew> I don't intend to use Linux on it
2014-07-07T02:21:57 < dongs> then find some other processor
2014-07-07T02:22:20 < eclipnew> Why won't it be good for bare metal?
2014-07-07T02:22:48 < eclipnew> I can have access to huge ram
2014-07-07T02:23:02 < dongs> also if yourereally using imx and not trolling, you should just go download codewarrior shit (which is actualyl rebranded freescale eclipse now) and use that.

2014-07-07T02:23:18 < karlp> arm926 in 2014 is only useful if you're trying to repurpose some existing shit you have a mountain of, why would you choose to do a new design on that?
2014-07-07T02:23:55 < dongs> karlp: beacuse trolling in here on request of #stonerstronics is "funny"
2014-07-07T02:23:59 < dongs> (when its actually not)
2014-07-07T02:24:02 < eclipnew> Code Warrior don't support imx I think
2014-07-07T02:24:57 < dony> hello I'm sending data to the bluetooth module through USART on my stm32 shouldn't I be getting an interrupt to handle data being sent back from the bluetooth module?
2014-07-07T02:25:07 < eclipnew> I checked Freescale website and there is no link to Code Warrior from imx webpages
2014-07-07T02:25:53 < eclipnew> karlp: Because imx28 is easy to route with only 4 layers
2014-07-07T02:27:00 < dongs> lol.
2014-07-07T02:27:06 < eclipnew> karlp: It has integrated PMU which make things simple for first time ARM mpu design
2014-07-07T02:28:12 < eclipnew> Not to mention the cost is low
2014-07-07T02:28:22 < dongs> LPC4357 has sdram controller. so does STM32F429 or so.
2014-07-07T02:28:29 < dongs> both can be routed on 2 layers.
2014-07-07T02:28:35 < dongs> and the cost is low.
2014-07-07T02:29:00 < eclipnew> sdram is more expensive than ddr2
2014-07-07T02:29:03 < dony> can someone help me?
2014-07-07T02:29:26 < dongs> eclipnew: please show me your ddr2 layout screenshots
2014-07-07T02:29:32 < qyx_> how much ram do you need if you are considering ddr2?
2014-07-07T02:29:46 < eclipnew> 1gbit
2014-07-07T02:29:47 < qyx_> also, do you need mmu?
2014-07-07T02:29:58 < eclipnew> dongs: It's not yet routed
2014-07-07T02:30:10 < dongs> eclipnew: i dont think it will ever be
2014-07-07T02:30:35 < qyx_> so you are going to do bare-metal on arm with 1gbit of ddr2?
2014-07-07T02:30:44 < eclipnew> That's right
2014-07-07T02:30:49 < dongs> a likely scenario.
2014-07-07T02:31:20 < eclipnew> I need that amount to do some bitmap image processing
2014-07-07T02:31:41 < qyx_> it will be fast for sure
2014-07-07T02:31:41 < dongs> eclipnew: do you have a link to your kickstarter
2014-07-07T02:31:52 < eclipnew> But I don't need the complexity of Linux
2014-07-07T02:32:16 < eclipnew> dongs: you mean the design?
2014-07-07T02:32:22 < qyx_> the complexity of higher level os allows you to make things simpler
2014-07-07T02:32:54 < dongs> eclipnew: no, kickstarter
2014-07-07T02:33:47 < eclipnew> qyx_: I agree, but Linux is an overhead for what I intent to do
2014-07-07T02:33:55 < qyx_> overhead?
2014-07-07T02:34:19 < eclipnew> dongs: kickstarter? I'm not sure I understand this term
2014-07-07T02:34:48 < qyx_> he is asking because this sounds like typical kickstarter project
2014-07-07T02:34:49 < eclipnew> qyx_: one is Linux isn't really real time

2014-07-07T04:57:23 < dongs> if you're in "final stages" that means it should take you max a week to crank out 1k of these fucking things

2014-07-07T10:37:59 < dongs> ive used it on F2

2014-07-07T10:43:11 < dongs> there's 2 addreses for different fsmc banks
2014-07-07T10:43:55 < xkonni> yes exactly. the lcd does split the mem though, 0x6000 for cmd and 0x6200 for data...
2014-07-07T10:43:56 < dongs> nand was command and data regions? if I remember correctly
2014-07-07T10:44:15 < xkonni> + 0000 each btw

2014-07-07T10:47:00 < xkonni> thats what i'm currently doing... writing and reading to 0x2000 0000 works, from 0x6000 or 0x6200 does not
2014-07-07T10:47:12 < dongs> then its not on..
2014-07-07T10:47:20 < dongs> or wrong bank or wahtever
2014-07-07T10:47:39 < jpa-> how does it not work?
2014-07-07T10:47:56 < xkonni> i'll double check that... but if i use LCD_SendData(123) it does show on the display
2014-07-07T10:48:17 < dongs> sounds like you have a mix of high and low level stuff without understanding how it works
2014-07-07T10:48:23 < xkonni> exactly
2014-07-07T10:48:36 < jpa-> just look at what lcd_senddata() does and do the same?
2014-07-07T10:49:05 < dongs> since LCD has separate cmd/data addresses, it very well could be that entire screen space isnt mapped
2014-07-07T10:49:16 < dongs> and you need to select address by cmd, then its available at 0x60000 for writing
2014-07-07T10:49:17 < dongs> or reading
2014-07-07T10:49:17 < dongs> etc
2014-07-07T10:49:40 < xkonni> dongs: the datasheets say it is mapped... but i fear you may be right
2014-07-07T10:50:23 < xkonni> or i just initialised it wrong
2014-07-07T10:50:30 < xkonni> or both

2014-07-07T10:53:43 < jpa-> so you do LCD_SendData(123) and it works, and you do exactly the same code that is inside LCD_SendData and it no longer works??
2014-07-07T10:55:13 < xkonni> i rewrote the lcd functions and it did not work, i actually dont need the lcd, just want to store received data in the psram
2014-07-07T10:55:36 < jpa-> so lcd works and some other psram chip does not?
2014-07-07T10:55:41 < Simon--> dongs: if I do SPI2->DR = foo, scope shows two bytes transmitted. if I do *(__IO uint8_t *)&SPI2->DR = foo, one byte transmitted. I see this is also done in stdperiph
2014-07-07T10:55:53 < Simon--> dongs: no biggy. maybe it's a feature
2014-07-07T10:55:57 < jpa-> have you configured the psram bank?

2014-07-07T11:44:09 < jpa-> xkonni: it has no address lines => the ram is not mapped into address space

2014-07-07T12:07:33 < Abhishek__> xkonni: so from the BOM it means that there's RAM as well as the LCD
2014-07-07T12:07:46 < jpa-> xkonni: maybe the psram is in different bank and in no way related to the LCD?
2014-07-07T12:07:53 < Abhishek__> could be
2014-07-07T12:07:56 < jpa-> then you just have to configure the fsmc bank 2 to work with the psram

2014-07-07T12:11:10 < Abhishek__> you might have to see the address pins going into the RAM and going to the LCD (the RS pin)
2014-07-07T12:17:36 < jpa-> xkonni: how do you figure that?

2014-07-07T14:07:59 < Tectu_> there was some fancy way to automatically place the new parts in pcbnew in a grid, rather than all stacked on top of each other, no?
2014-07-07T14:08:04 < Tectu_> kicad that is
2014-07-07T14:16:54 < __rob> is there an alternative printf I can use with semihosting, or some function I can add myself thats a bit lighter then the default
2014-07-07T14:17:07 < __rob> seems to use loads of memory to do a simple print, and I get hardfaults with FreeRTOS
2014-07-07T14:18:32 < Thorn> >I want to make one thing crystal clear - Windows, in some regards, is even worse than Linux and it's definitely not ready for the desktop either.
2014-07-07T14:25:24 < Tectu_> Thorn, where did you catch that?
2014-07-07T14:25:35 < Tectu_> __rob, there are about a trillion open printf implementation out there
2014-07-07T14:26:04 < Tectu_> __rob, and the thing that usually takes up the memory is float support so printf() routines targetting embedded targets either don't have that support or it is optional through a macro
2014-07-07T14:26:57 < Thorn> Tectu_: http://linuxfonts.narod.ru/why.linux.is.not.ready.for.the.desktop.current.html
2014-07-07T14:27:58 < Tectu_> Thorn, I love that 80% of the article is about X and wayland
2014-07-07T14:28:19 < Tectu_> Thorn, especially the parts where he bitches around that wayland is not ready yet and lacks features - which is exactly what the wayland people tell you
2014-07-07T14:28:50 < Tectu_> that's one typical open source problem... somebody relealses some 0.2 version release and labels it alpha, somebody picks it up and bitches around that it is far from usable

2014-07-07T15:22:04 < __rob> Tectu, most of the ones I've found seem to expect me to implement the actual bit to output the character
2014-07-07T15:22:41 < __rob> I don't want to have to wire up a uart to output data, so I want to do it via semihosting, just trying to figure out how to actually do that

2014-07-07T15:24:26 < __rob> great, thanks
2014-07-07T15:24:52 < __rob> bit confused though. The stuff I have found this far put the 0x3 (SYS_WRITEC) into r0 and the ptr in to r1
2014-07-07T15:25:01 < __rob> then execute a svc instruction with 0xab for thum
2014-07-07T15:25:02 < __rob> b
2014-07-07T15:25:44 < __rob> I assumed that was the mechanism that got the hardware to actually output the character to the programmer ?
2014-07-07T15:25:57 < jpa-> svc 0xab and bkpt 0xab do basically the same
2014-07-07T15:26:02 < jpa-> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0471c/Bgbjhiea.html
2014-07-07T15:26:26 < jpa-> i think bkpt 0xab is (more) correct for cortex-m3
2014-07-07T15:26:27 < __rob> great. unfortunately FreeRTOS have an SVC handler (empty),

2014-07-07T15:26:33 < __rob> im on M0
2014-07-07T15:26:46 < __rob> with svc it just breaks into their handler..
2014-07-07T15:26:48 < jpa-> hmm.. that is armv6-m? so bkpt should work for it also
2014-07-07T15:27:00 < __rob> yea it is, ok i'll give it a try
2014-07-07T15:27:01 < __rob> thanks
2014-07-07T15:27:32 < jpa-> 0x03 is "write one byte", 0x05 is "write N bytes"
2014-07-07T15:28:23 < __rob> the infocenter url says "SVC 0xAB - In ARM state and Thumb state, excluding ARMv6-M and ARMv7-M"
2014-07-07T15:28:49 < __rob> so mabye it wouldn't have worked with my M0 anyway.. even with the default svc handling..
2014-07-07T15:29:46 < __rob> so if the svc handler is not implemented by freertos, or otherwise. Is there something in hardware that will handle this and transfer the character(s) ?
2014-07-07T15:29:57 < __rob> or does a defalt handler that does this get linked in
2014-07-07T15:30:09 < jpa-> it happens in hardware
2014-07-07T15:30:19 < jpa-> (or mostly, it happens on the host side by the debugger)

2014-07-07T18:36:51 < gxti> more likely you're not receiving it correctly

2014-07-07T18:43:58 < dongs> then you dont need to care about delays/etc.

2014-07-07T19:45:32 < synic> is there mbed on the regular discovery boards, or just the nucleo ones?
2014-07-07T19:45:42 < Steffanx> don't know synic
2014-07-07T19:46:54 < synic> btw, I tried mbed for a bit.  For doing anything other than dinking around on their supported dev boards, it seems pretty useless, at least (or especially) for stm32 chips

The analog values are clocked out from this chip in sequence, going straight into an Arduino Due for processing, saving, and displaying on a small screen.

2014-07-08T06:35:04 < upgrdman> any of the low cost swd/jtag programmers also have a built in uart or bare-bones logic analyzer for help in the development phase?

2014-07-08T06:36:21 < GargantuaSauce> uh, cause everyone doesnt have a multifunction printer on their desk?
2014-07-08T06:36:53 < Thorn> upgrdman: some olimex ftdi ones have uart, BMP has one too
2014-07-08T06:37:29 < upgrdman> k
2014-07-08T06:39:00 < dongs> i would suggest just getting jlinkob for $13 and $3 cp2102 usb>uart shit from eby
2014-07-08T06:39:35 < dongs> http://www.hotmcu.com/usbminijtag-jlink-jtagswd-debuggeremula%E2%80%8Btor-p-29.html + http://www.ebay.com/itm/170946368201
2014-07-08T06:42:58 < upgrdman> i already have an ftdi. was just finding that i often need a usb hub when doing embedded dev work ... programmed, ftdi, log anal'er ... and wondered if maybe something thought to combine them.
2014-07-08T06:43:17 < upgrdman> what benefits might that jlink-ish thing have over the stlinkv2?
2014-07-08T06:43:42 < dongs> faster, has proper gdbserver w/o openocd aids
2014-07-08T06:44:04 < GargantuaSauce> its not just dev work...i have to have a usb hub sitting on my damn hexapod
2014-07-08T06:45:38 < upgrdman> dongs: so how does that work. the jlink appears as a usb uart, and you, uh, telnet into it?
2014-07-08T06:46:28 < upgrdman> well no, that doesn't make sense :) but, ya, how do you interact with it?
2014-07-08T06:46:32 < GargantuaSauce> no you just run the jlink gdb server software
2014-07-08T06:46:37 < upgrdman> o
2014-07-08T06:46:40 < dongs> ^ yea that
2014-07-08T06:46:43 < GargantuaSauce> which is like oocd but doesn't have open in the name so dongs likes it
2014-07-08T06:46:50 < Thorn> he goes start -> all programs -> SEGGER -> J-Link -> J-Link GDB Server via SWD
2014-07-08T06:46:55 < dongs> no, its not like oocd, cuz, it WORKS
2014-07-08T06:47:34 < upgrdman> so why does jtag need/want 20 pins? :)
2014-07-08T06:47:46 < dongs> it doesnt
2014-07-08T06:47:53 < dongs> like 11 of t hem is gnd?
2014-07-08T06:47:54 < GargantuaSauce> so you can have 11 grounds
2014-07-08T06:47:56 < dongs> or more even
2014-07-08T06:47:57 < dongs> yeah
2014-07-08T06:48:22 < upgrdman> lol. why so many?
2014-07-08T06:48:28 < dongs> its called standards
2014-07-08T06:48:37 < GargantuaSauce> so your ribbon cable can pretend to be coaxial

2014-07-08T06:50:47 < GargantuaSauce> make a 40 channel speaker array

2014-07-08T15:16:47 < dongs> whats wrong with eclipse? gcc-arm-embdeeded?
2014-07-08T15:17:04 < dongs> god damn im failing basic C
2014-07-08T15:17:26 < dongs> #if defined(FAG) .. #elsif defined(FAG2) ... #else ... #endif
2014-07-08T15:17:27 < dongs> doesnt fucking work
2014-07-08T15:17:36 < mansfeld> never managed to get it working reliably with the debugger
2014-07-08T15:17:47 < dongs> then pay $150 for crossworks edu
2014-07-08T15:18:45 < mansfeld> can't, it's for commercial work :3
2014-07-08T15:19:12 < karlp> so open up your wallet then
2014-07-08T15:19:34 < mansfeld> mostly I was wondering if anyone else was using it and if it had also just stopped working coincidentally the same day they released a new version
2014-07-08T15:20:44 < mansfeld> we already have a commercial license (unlimited time) with 1 year support that I've never had to use and that expired a few days ago
2014-07-08T15:21:08 < dongs> renew it
2014-07-08T15:21:18 < dongs> truestudio always felt kinda shit tho
2014-07-08T15:21:21 < dongs> cuz its just rebranded eclipse
2014-07-08T15:21:23 < dongs> charging money for opensores
2014-07-08T15:21:26 < dongs> and making it shitty
2014-07-08T15:21:33 < dongs> you might as well spend time making eclipse + gcc wokr
2014-07-08T15:21:34 < dongs> its not that hard
2014-07-08T15:21:35 < mansfeld> and expensive :/
2014-07-08T15:21:37 < dongs> shit all over google
2014-07-08T15:22:03 < mansfeld> yeah, I think i'll be trying that again at some point, I'm really getting fed up with truestudio
2014-07-08T15:22:15 < karlp> yeah, we tried atollic here, it didn't feel like it offered much

2014-07-08T18:44:38 < xkonni> somehow i still struggle with FSMC PSRAM. writing 16bit words to BASE also writes the same word to BASE+8, writing to BASE+8 writes the same word to BASE, but not to BASE+16...
2014-07-08T18:45:22 < xkonni> repeats each 8 words.

2014-07-08T18:46:51 < xkonni> is it possible i didnt map the address-gpio4?
2014-07-08T18:47:04 < zyp> ah, that might be
2014-07-08T18:47:14 < zyp> or otherwise fucked up one addr line

2014-07-08T18:48:09 < xkonni>     *( uint16_t volatile*) (FSMC_SRAM_ADDR) = 1;
2014-07-08T18:48:25 < zyp> ok, I take it that you didn't design the hardware?
2014-07-08T18:48:30 < xkonni> no
2014-07-08T18:48:55 < zyp> did you write the code to configure the FSMC?
2014-07-08T18:49:11 < zyp> or did it come from a source that was supposed to be working?
2014-07-08T18:49:13 < xkonni> i adapted it from a stm32f1 example for my stm32f4
2014-07-08T18:49:41 < xkonni> but if the missing gpio is possible i'll double check those first

2014-07-08T18:49:52 < zyp> yeah, sounds like that might be your best bet
2014-07-08T18:50:13 < xkonni> the write/read code is so simple, thats not very likely to be wrong... i think...
2014-07-08T18:51:03 < zyp> true
2014-07-08T18:51:25 < zyp> sounds like either gpio misconfiguration or hardware error on one of the addr lines

2014-07-08T19:00:43 < dongs> http://www.digikey.com/product-detail/en/STM32F072B-DISCO/497-14098-ND/4502081 hey this is in stock
2014-07-08T19:00:57 < dongs> wonder if I should join it in my collection of -disco boards ill never use
2014-07-08T19:01:12 < zyp> I have it, never used it so far
2014-07-08T19:01:18 < dongs> as expected
2014-07-08T19:01:35 < zyp> and since M0 is too dumbed down, I'll probably wait for L0 with M0+ instead
2014-07-08T19:02:07 < dongs> http://www.digikey.com/product-detail/en/STM32L152C-DISCO/497-13661-ND/4022627 you mean these??
2014-07-08T19:02:31 < zyp> no, L0
2014-07-08T19:02:34 < dongs> http://www.digikey.com/product-detail/en/STM32L0538-DISCO/497-14709-ND/4866483
2014-07-08T19:02:36 < dongs> oh this then
2014-07-08T19:02:52 < __rob> how is m0 dumbed down?
2014-07-08T19:03:13 < zyp> no SCB_VTOR, that's the dealbreaker
2014-07-08T19:03:14 < karlp> no relocatable vectors is probably what zyp means, fixed in m0+
2014-07-08T19:03:18 < dongs> no hw divide, no remapping interrupt vectors

2014-07-08T19:05:22 < zyp> I don't need hardware divide, but I want the possibility to do custom bootloaders in a sane way

2014-07-09T03:50:25 < upgrdman> anyone here into photography? i often use a hotshoe flash to bounce light off a ceiling or wall... do they make any that have multiple flashes that can be aimed independently? like a hotshoe flash with two flashes on goosenecks or piviting things?
2014-07-09T03:53:47 < superbia> never seen one with multiple flashes
2014-07-09T03:55:43 < upgrdman> me neither :(
2014-07-09T03:56:37 < superbia> u can buy independent units

2014-07-09T03:58:33 < superbia> i saw photographers have independant flashes attached to their jackets.

2014-07-09T04:17:48 < gxti> hrm, weird issue with etherbutts. half the time after a reset it will permanently get 50% packet loss until next reset. the other half it works perfectly. PHY is hard reset on powerup.
2014-07-09T04:18:17 < gxti> i think it might only affect this one board...

2014-07-09T04:25:48 < gxti> this failboard is an older one, not even the latest batch
2014-07-09T04:33:06 < dongs> jeeez
2014-07-09T04:40:27 < upgrdman> do eeproms use pages or are they writable by byte?
2014-07-09T04:41:41 < gxti> as far as i know they all allow byte writes
2014-07-09T04:42:41 < gxti> they do still have pages though (of e.g. 8 bytes) and you have to start a new write command for each different page
2014-07-09T04:43:08 < upgrdman> ok
2014-07-09T04:43:09 < dongs> eh
2014-07-09T04:43:16 < dongs> i2c eeproms (low byte count shit) is all byte-addressable
2014-07-09T04:43:21 < upgrdman> good
2014-07-09T04:43:23 < gxti> yeah, o2c
2014-07-09T04:43:24 < gxti> i2c
2014-07-09T04:43:32 < dongs> there are additional modes
2014-07-09T04:43:41 < dongs> wehre you can do faster reads/writes but default access way is byte
2014-07-09T04:43:52 < upgrdman> the flash on an stm32 isn't byte addressable, is it?
2014-07-09T04:44:00 < dongs> you have to erase page
2014-07-09T04:44:05 < dongs> before writing.
2014-07-09T04:44:13 < upgrdman> k
2014-07-09T04:44:23 < dongs> for reads, just stick a pointer to struct to flash page address.
2014-07-09T04:44:29 < upgrdman> ya
2014-07-09T04:46:23 < gxti> hrm, never mind on packet loss. if i use a different IP it goes away. but nothing has been on that IP for a long time...

2014-07-09T10:19:28 < efuentes> I'm a little shaky with arm assembly but I'm hoping you guys can help me out
2014-07-09T10:19:54 < efuentes> so I've got this instruction
2014-07-09T10:19:55 < efuentes> ldr ip, [r1], #4
2014-07-09T10:20:06 < efuentes> and it's written for a cortex-m3
2014-07-09T10:20:12  * superbia snuggles
2014-07-09T10:20:12 < efuentes> and from what I understand
2014-07-09T10:20:26 < efuentes> it takes a word from the address contained in r1
2014-07-09T10:20:30 < efuentes> and stores in ip
2014-07-09T10:20:36 < efuentes> and increments r1 by 4
2014-07-09T10:20:47 < efuentes> sorry
2014-07-09T10:20:49 < efuentes> that should be
2014-07-09T10:20:54 < efuentes> ldr.w ip, [r1], #4
2014-07-09T10:21:24 < efuentes> I need to rewrite it into something that an m0 can understand
2014-07-09T10:21:54 < efuentes> it looks like this generates a 32bit arm instruction
2014-07-09T10:22:06 < superbia> and u need 16 ?
2014-07-09T10:22:09 < efuentes> right
2014-07-09T10:22:13 < superbia> gosh
2014-07-09T10:22:26 < efuentes> so i should be able to break it up into a load and an add
2014-07-09T10:22:40 < superbia> dongie knows this.. we shall wait till he comes online

2014-07-09T12:46:16 < __rob> the minimum resolution is 1 tick
2014-07-09T12:46:55 < __rob> and the tick rate is defined in your freertosconfig

2014-07-09T12:54:26 < tylerdurden> i found this line #define portTICK_RATE_MS			( ( portTickType ) 1000 / configTICK_RATE_HZ )
2014-07-09T12:54:38 < tylerdurden> and #define configTICK_RATE_HZ				( ( portTickType ) 1000 )
2014-07-09T12:54:47 < dongs> yes systick is 1kHz usually
2014-07-09T12:54:50 < __rob> #define configTICK_RATE_HZ
2014-07-09T12:54:52 < dongs> you can certainly delay fgor less if you wanted to
2014-07-09T12:54:54 < __rob> thats the one you want to change
2014-07-09T12:55:01 < dongs> i dont think you wanna change systick
2014-07-09T12:55:44 < tylerdurden> ok so if we change the configTICK_RATE_HZ will it effect the tasks functionality
2014-07-09T12:55:52 < __rob> I've found if you want an accurate delay inbetween ticks, its better to setup a timer, have the task wait on a semaphore, and then switch the context to that task and unlcok the semiphore inside the isr
2014-07-09T12:56:11 < dongs> tylerdurden: yes, and you shouldnt be fuckign with that unless you know what youre doing
2014-07-09T12:56:19 < __rob> it will switch between tasks more often tylerdurden
2014-07-09T12:56:19 < dongs> __rob: exactly
2014-07-09T12:56:39 < dongs> i have a generic timer callback interface liek that in a few projects
2014-07-09T12:58:14 < __rob> how long is your delay tylerdurden, and how accurate does it need to be ?

2014-07-09T15:21:20 < mansfeld> hi folk! So I followed your advice yesterday to try out Eclipse instead of Atollic, and after a bit of messing around, I'm able to get my project to compile neatly and connect to a debugger. I still have one problem though, and I think it's that the .isr_vector isn't being included in the output.
2014-07-09T15:22:02 < mansfeld> Does anyone know what I've missed? Here's a sample from the beginning of the hex file that shows the missing section in the new hex file : http://pastebin.com/SGM91VBR
2014-07-09T15:24:11 < mansfeld> (I'm using the same linker script as before, to place the code at 0x08003000 (bootloader occupies 0x080000000 to 0x08003000) )
2014-07-09T15:24:52 < Tectu_> if there's an advice about eclipse in this world, then it is "avoid it"
2014-07-09T15:24:59 < Tectu_> can't tell anything about atollic, tho
2014-07-09T15:26:12 < mansfeld> hehe, well this seems to be a problem with how the GNU ARM toolchain is setup rather than Eclipse itself
2014-07-09T15:29:15 < mansfeld> as far as I can tell after working with atollic is that it's the same as eclipse with a few added features, and a lot of 'magic', with the end result that I did quite a few things without actually understanding what I was doing...
2014-07-09T15:34:34 < Thorn> eclipse itself is not bad

2014-07-09T18:15:41 < Cyric> put a single char... but i am not sure if compile it.. was just a small dubt...
2014-07-09T18:22:26 < Cyric> so just for be clear... if i write Usart1Put("0x48") it consider that a string so 4 chars...
2014-07-09T18:22:52 < Cyric> if i write Usart1Put(0x48); than it consider it one char with hex code 48
2014-07-09T18:23:10 < Cyric> and if i write Usart1Put(48); it consider one char with decimal code 48

2014-07-09T22:17:32 < emeb> Hey ds2
2014-07-09T22:17:40 < emeb> something you might be interested in: http://ebrombaugh.studionebula.com/radio/hfrx/index.html
2014-07-09T22:20:02 < SlaveToTheSauce_> cool
2014-07-09T22:21:20 < ds2> interesting... how's this mixer different from the mixers using just analog mux?
2014-07-09T22:21:57 < emeb> ds2: "just analog mux" as opposed to what?
2014-07-09T22:22:17 < emeb> ie - which mixers are you talking about?
2014-07-09T22:22:18 < ds2> emeb: vs what you have here... I have seen designs using the 4066 (I think) as the mixer
2014-07-09T22:22:47 < ds2> LO drives the mux control and the signal is fed into the mux through the normal path
2014-07-09T22:23:25 < emeb> ds2: aha - this particular mux chip has much higher-quality switches than an oldskool 4066
2014-07-09T22:23:39 < ds2> I see
2014-07-09T22:23:57 < emeb> do the ones you mention use the quadrature approach?
2014-07-09T22:25:50 < emeb> ds2: it's possible to do a sampling detector where the LO runs at the tuning freq, but that only gives you a unipolar real signal.
2014-07-09T22:26:09 < ds2> I don't recall on the older ones
2014-07-09T22:26:33 < emeb> this QSD approach runs the LO at 4x the tuning freq, but provides a differential I & Q signal that's better for SSB and digital modes.
2014-07-09T22:26:34 < ds2> it might have been an article from a rag... not sure if it is a ham rag, PE/RE rag, or wireless world
2014-07-09T22:26:53 < emeb> right
2014-07-09T22:27:14 < ds2> since you generate analog I/Q pair, does that mean I can do SSB detection using the phasing method if I do not want to digitize?
2014-07-09T22:27:21 < emeb> yes
2014-07-09T22:27:23 < ds2> weaver I think is the name of the method
2014-07-09T22:27:31 < ds2> ooh nifty
2014-07-09T22:27:32 < emeb> yes - mentioned in the text.
2014-07-09T22:27:45 < ds2> sorry, I jumpped to the schematic first
2014-07-09T22:27:48 < emeb> Tayloe's radio is all analog but uses this for the front-end.
2014-07-09T22:28:13 < emeb> the analog weaver approach requires a lot of hairy filters though - easier to do in DSP. :)
2014-07-09T22:28:21 < ds2> I have a 25 year old background project to do a "HF" radio
2014-07-09T22:28:45 < ds2> really? the articles I have seen just shows a few mixers
2014-07-09T22:28:55 < ds2> this is stuff from the 60's or 70's
2014-07-09T22:29:22 < emeb> it's more than just mixers if you're doing it at baseband.
2014-07-09T22:29:45 < emeb> sum/diff networks and phase correction filters, etc.
2014-07-09T22:30:01 < emeb> google for Tayloe's design - it's pretty well documented.
2014-07-09T22:30:03 < ds2> even for narrow band SSB stuff like what hams use?

2014-07-09T22:31:11 < ds2> I see... I'll dig out the articles one of these days
2014-07-09T22:32:21 < ds2> how 'clean' are the ADCs on the STM32 part you are looking ?
2014-07-09T22:32:32 < emeb> Here's an example - mostly analog: http://circuitsalad.com/2013/12/30/my-phasing-receiver-is-a-success/
2014-07-09T22:33:02 < emeb> ds2: the SDADCs are 16-bit differential and spec'd for ~88dB SNR

2014-07-09T22:33:29 < emeb> I'm sure that's highly dependent on the layout, but if I can get close to that then it should give good dynamic range.
2014-07-09T22:34:06 < ds2> no tuned circuits? sounds like a recipe for overload from local AM stations
2014-07-09T22:34:31 < ds2> that's spec'ed...what is it in reality :D
2014-07-09T22:35:01 < emeb> ds2: valid point, and part of the reason I'm trying it.
2014-07-09T22:35:05 < ds2> reason I am asking is - I am thinking of tackling the noise on the BBB's ADC once again...things cannot be as bad as they are
2014-07-09T22:35:33 < emeb> I've not messed with the BBB ADCs - what have you seen?

2014-07-09T22:35:54 < ds2> very very noisy
2014-07-09T22:36:20 < ds2> last time I was rushing to get a demo together.... think I am going to have to sit down and characterize it
2014-07-09T22:36:46 < emeb> ds2: Most on-chip ADCs in modern MCUs & SoCs are pretty noisy.
2014-07-09T22:36:46 < ds2> thinking of gathering data with the inputs tied to ground via a 1K resistor to simulate a reference signal
2014-07-09T22:37:00 < emeb> and that's usually exacerbated by poor board layout.
2014-07-09T22:37:10 < ds2> what's noisy in this context? 4-6 bits of useable data on a 12bit ADC?
2014-07-09T22:37:21 < emeb> Usually better than that
2014-07-09T22:37:41 < ds2> "Usually"? hmmm that is not a good sign when you use that word
2014-07-09T22:37:44 < emeb> On STM32 parts w/ 12-bit converter I usually get about 8-10 good bits.
2014-07-09T22:38:14 < ds2> is that 8-10 bits of raw data or post processed to get 8-10bits?
2014-07-09T22:38:20 < emeb> that's raw.
2014-07-09T22:38:45 < emeb> if you do filtering, etc you can get more like 11 bits
2014-07-09T22:39:05 < ds2> what kind of filtering? 100000000000000 tap FIR?
2014-07-09T22:39:05 < ds2> :D
2014-07-09T22:39:25 < emeb> I generally just do boxcar filters
2014-07-09T22:39:44 < emeb> either integrate/dump or moving average. 16 samples is usually enough
2014-07-09T22:39:59 < ds2> Oh
2014-07-09T22:40:17 < ds2> 16 is enough? Hmmmm
2014-07-09T22:40:23 < emeb> 16 samples cuts noise by 12dB - an extra 2 bits of SNR
2014-07-09T22:40:25 < ds2> I must try enabling that in HW
2014-07-09T22:40:58 < ds2> does it ever help to convert to differntial ?
2014-07-09T22:41:09 < emeb> generally yes, if your ADC supports it
2014-07-09T22:41:15 < emeb> most on-chip noise is common-mode
2014-07-09T22:41:26 < emeb> so differential cancels out much of the on-chip noise.
2014-07-09T22:41:34 < ds2> so a xformer is not going to make things worse?
2014-07-09T22:41:56 < ds2> it seems most on chip ADCs I have seen support diff mode but it is rarely used
2014-07-09T22:42:28 < emeb> I think that it's less-often used because it's more complex
2014-07-09T22:42:40 < emeb> more pins on the MCU/SoC, more external parts, etc.
2014-07-09T22:42:54 < emeb> so only hard-core apps would use it.
2014-07-09T22:43:20 < ds2> but isn't a small signal xformer a easier way to improve noise then doing all sorts of other sw shannagans?
2014-07-09T22:43:48 < emeb> ds2: not all applications can stand a transformer
2014-07-09T22:43:59 < jpa-> bah.. what's wrong with people.. "I'm getting error on line 9, what should I do?????"  https://gist.github.com/PetteriAimonen/c6ca68b798ab7430f8ba#file-gistfile1-c-L9
2014-07-09T22:44:03 < emeb> if you're sampling low freq signals then an xfrmr is not an option.
2014-07-09T22:44:11 < ds2> ah
2014-07-09T22:44:13 < jpa-> dunno how i could possibly make that clearer
2014-07-09T22:44:52 -!- Cyric [~Someone@cm-84.211.79.184.getinternet.no] has joined ##stm32
2014-07-09T22:44:57 < emeb> ds2: also, xfrmr requires careful control of impedances and many on-chip converters have fairly unpredictable input impedances.
2014-07-09T22:45:44 < ds2> given how dirty the signals are, is the impedence mismatch going to cause more problems then it solves?
2014-07-09T22:46:39 < emeb> good question
2014-07-09T22:47:05 < ds2> from looking at datasheets, the impedence of an ADC is more or less undefined :(
2014-07-09T22:47:19 < emeb> and there's the problem.
2014-07-09T22:47:25 < emeb> better off using analog diff-amps.
2014-07-09T22:47:45 < emeb> and those have the advantage of providing DC response as well.
2014-07-09T22:48:22 < ds2> except those things want a high voltage and have these nasty poles and such to compensate for
2014-07-09T22:48:41 < emeb> and now you see why diff mode inputs aren't often used.
2014-07-09T22:49:08 < ds2> the more I learn about op-amps, the less I like it
2014-07-09T22:50:18 < emeb> the advantage I have with the QSD and the F373 is that the QSD naturally puts out diff-mode signal.

2014-07-09T23:29:29 < ds2> hmmmm high voltage
2014-07-09T23:30:43 < emeb> ?
2014-07-09T23:31:14 < ds2> 3.3V is HV :D
2014-07-09T23:31:47 < ds2> I suppose that gets you head room
2014-07-09T23:31:50 < emeb> if you're driving the BBB ADC inputs you can just lower the offset.
2014-07-09T23:32:09 < ds2> is that enough?
2014-07-09T23:32:20 < ds2> I'd think I need to feed it through a 2:1 divider
2014-07-09T23:32:21 < emeb> take it from 1.67V mid-scale to 0.9V
2014-07-09T23:32:40 < ds2> but that doesn't change the peaks
2014-07-09T23:33:15 < emeb> just means that your max input signal level is lower - +/-0.9V instead of +/-1.67V
2014-07-09T23:33:39 -!- upgrdman [~upgrdman@blender/artist/upgrdman] has quit [Quit: This computer has gone to sleep]
2014-07-09T23:34:06 < ds2> why +/-0.9V? isn't it still a 0-3.3V signal that you just moved the center line?
2014-07-09T23:34:27 < emeb> depends on what the input to the op-amp is.
2014-07-09T23:34:52 < emeb> if you're talking about my HFRX board then the signal level is whatever exists at the carrier frequency on the RF input.
2014-07-09T23:35:02 < emeb> which is generally going to be pretty small
2014-07-09T23:35:17 < ds2> even if I walked near an AM antenna tower?
2014-07-09T23:35:17 < emeb> (times the gain of the amp stage)
2014-07-09T23:35:34 < ds2> the BBB's ADC has a spec'ed hard limit of 1.8V or bad things happen in HW
2014-07-09T23:35:38 < emeb> Only if you're tuned to that tower
2014-07-09T23:35:52 -!- so [~Someone@cm-84.211.79.184.getinternet.no] has joined ##stm32
2014-07-09T23:36:14 < emeb> but yeah - you might want to put some sort of hard clipping ckt in if the ADC inputs are sensitive to over voltage
2014-07-09T23:36:25 < ds2> ah... so the filter on the mixer will prevent the tower from overloading things?
2014-07-09T23:36:33 < emeb> Use a schottky diode to the 1.8V supply or something.
2014-07-09T23:37:21 < emeb> right - the QSD output only carries signals within a few kHz of the LO freq.

2014-07-10T07:45:12 < dongs> also thats really cheap, i wonder if there's something similar to DP++ stuff where it can be DP or HDMI

2014-07-10T07:47:52 < GargantuaSauce> wifi dongles dont push 10 gigabits
2014-07-10T07:47:53 < upgrdman> silicon doesnt have to be expensive
2014-07-10T07:48:00 < upgrdman> true
2014-07-10T07:48:37 < GargantuaSauce> yeah i am going to guess the thunderbolt controller an also just do hdmi or dp signalling
2014-07-10T07:48:38 < dongs> i dunno, but that is crazy cheap. there are DP>HDMI bridge chips, (just like the shit im using), but then you have to support thunderbolt power, so at least 2-3 chips in there
2014-07-10T07:48:53 < dongs> GargantuaSauce: there's DP on it, i know that much but I duno if it can dual-mode
2014-07-10T07:49:14 < dongs> and from what little specs ive seen on thunderdong its either 3.3V or like 18V
2014-07-10T07:49:27 < dongs> and some negotiation required to get that power bla bla
2014-07-10T07:50:05 < dongs> but, if it really is active, I should  buy it and see what chips it used :)
2014-07-10T07:50:38 < dongs> * Elegant white colour, consistent with your Apple computers;
2014-07-10T07:50:46 < GargantuaSauce> ya learning that sounds like it's worth $10
2014-07-10T07:50:50 < GargantuaSauce> better than buying the specs lol
2014-07-10T07:51:15 < dongs> In Stock. Ships from BC, Canada. Expedited shipping available.

2014-07-10T15:03:13 < BrainDamage> by combinining multiple nics you can achieve pretty decent speeds
2014-07-10T15:03:26 < Steffanx> or that. Reminds me of some PoE powered camera outside. Some pins where completely gone
2014-07-10T15:03:26 < madist> what is that yagi like thing ? with all equal length resonators ?
2014-07-10T15:03:49 < BrainDamage> by the dipole size I'd eyeball it's a 2.4GHz yagi
2014-07-10T15:04:02 < superbia> 2.4GHz cheap ebay internet jewtool
2014-07-10T15:04:03 < madist> but what's the point of all the reflectors being the same size ?
2014-07-10T15:04:06 < BrainDamage> and a yagi has all dipoles of the same size, you're thinking of a log periodic
2014-07-10T15:04:13 < BrainDamage> it increases directivity
2014-07-10T15:04:19 < BrainDamage> and filters out other signals
2014-07-10T15:04:34 < BrainDamage> log periodic instead want to be broadband
2014-07-10T15:04:46 < BrainDamage> which is why the differently sized resonators

2014-07-10T16:31:39 < dongs> its fucking terrible from obvious offset silk to shittastic 6/6
2014-07-10T16:31:52 < dongs> i think the plated parts on 6/6 are shorting
2014-07-10T16:31:57 < dongs> which im not too surpriseed about
2014-07-10T16:32:05 < dongs> those fucks managed to short a 2L board for me, like 5 out of 10
2014-07-10T16:32:10 < dongs> wiht like 8/8 rules
2014-07-10T16:32:22 < Steffanx> bad luck.
2014-07-10T16:32:57 < Steffanx> the dfn pads failed too or is that by design?

2014-07-10T19:33:32 < Steffanx> it does look very much like all the other eval board by st. You just have to find the right one
2014-07-10T19:33:35 < madist> MB542 is a ST board.
2014-07-10T19:33:50 < madist> grummund need to google moar.
2014-07-10T19:35:17 < madist> and I need to look more carefully.

2014-07-11T06:27:27 < upgrdman> well half-words. since you must write half-words.

2014-07-11T08:22:23 < dongs> zyp: theres a pic in the bottom
2014-07-11T08:22:29 < dongs> http://shop.emergeplus.jp/wp-content/uploads/2014/07/PB-00002-05.png
2014-07-11T08:22:34 < englishman> currently on tgv, faster than speeding bullet
2014-07-11T08:22:42 < zyp> ah, right
2014-07-11T08:22:52 < SlaveToTheSauce_> i am going to guess it's a spray-on enamel or something
2014-07-11T08:23:03 < SlaveToTheSauce_> cause acrylic is soft as shit
2014-07-11T08:23:05 < zyp> tempted to get one so I can actually use the panel I bought
2014-07-11T08:23:18 < zyp> because it's useless as is :p
2014-07-11T08:23:57 < zyp> also, will this fit the adapter board I got, or did the layout change too much?
2014-07-11T08:24:07 < dongs> but isnt your adapter board the super old one
2014-07-11T08:24:10 < dongs> before i sold 1000
2014-07-11T08:24:22 < zyp> yeah, first design with buttons on the side instead
2014-07-11T08:24:23 < dongs> yours is the one wiht i2c driver shit right?
2014-07-11T08:24:34 < dongs> yeah. not gonna fit. i better send you new one.
2014-07-11T08:24:34 < zyp> probably
2014-07-11T08:24:38 < dongs> i got a bunch of qcfail ones I can fix up
2014-07-11T08:24:58 < dongs> you got somewhere wehre you can receive mail locally?
2014-07-11T08:25:35 < zyp> yep

2014-07-11T15:42:46 < twixx> is it possible to use Update, Ch1, Ch2 of 2 timers as requests in one DMA? i like to use TIM3 and TIM4 on DMA1 of STM32f103. so i need to reserve channel 1,2,3,4,6 and 7 (no double use).
2014-07-11T16:13:08 < dongs> thats a lot of dma
2014-07-11T16:13:09 < dongs> waht are you doing?
2014-07-11T16:40:23 < scrts_w> dma instead of memcpy for the win!
2014-07-11T16:42:12 < dongs> heh
2014-07-11T16:42:14 < dongs> ive done that
2014-07-11T16:42:25 < dongs> instead of memzero() in my case
2014-07-11T16:42:33 < dongs> duno if it was really all that much faster.

2014-07-11T16:50:48 < dongs> wow thats some pretty hardcore shit
2014-07-11T16:51:01 < twixx> indeed
2014-07-11T16:52:05 < dongs> to answer your question..... i dont think so... cuz your "destination" peripheral is TIMx->CCRy or whatever
2014-07-11T16:52:09 < dongs> and they're not sequential or anything
2014-07-11T16:52:14 < dongs> maybe you can do some DMA slave stuff
2014-07-11T16:52:25 < dongs> duno how flexible that is
2014-07-11T16:52:30 < twixx> i got only one timer to work with dma. tested it with the transmission-complete interrupt. but i get only interrupts for one timer events. the other one is configured same way
2014-07-11T16:52:57 < twixx> no no i write mem->gpio
2014-07-11T16:53:07 < dongs> oh, why not use bitbanding then
2014-07-11T16:53:36 < twixx> its to fast and wastes cpu time
2014-07-11T16:53:45 < dongs> bitbanding?
2014-07-11T16:53:52 < dongs> the whole purpose of it is NOT to waste cpu time :p
2014-07-11T16:54:01 < twixx> or what do you mean? how?
2014-07-11T16:54:01 < dongs> not bitbanging
2014-07-11T16:54:05 < twixx> aaah ok
2014-07-11T16:54:13 < dongs> twixx: you can map GPIOx->stuff into memory regions
2014-07-11T16:54:21 < dongs> so that a single 32bit write sets 1 bit
2014-07-11T16:54:28 < dongs> your'e trying to quickly toggle gpio right?
2014-07-11T16:54:30 < dongs> based on timer stuff?
2014-07-11T16:54:33 < twixx> correct
2014-07-11T16:54:40 < dongs> right, bitband might be the a nswer
2014-07-11T16:54:53 < twixx> i am using BSRR register to set and reset pins simultanously
2014-07-11T16:55:08 < dongs> thats what you're DMA'ing to?
2014-07-11T16:55:58 < twixx> jepp
2014-07-11T16:56:09 < dongs> i'm pretty sure GPIO can be to any channel
2014-07-11T16:56:14 < dongs> so as long as youre not conflicting.. you should be O K
2014-07-11T16:56:28 < twixx> yes the gpio part is working good
2014-07-11T16:56:42 < twixx> but i only get dma events of one timer
2014-07-11T16:57:18 < twixx> but i need the second timer, because there are some pins on an other gpio port to
2014-07-11T16:57:20 < twixx> too

2014-07-11T16:58:03 < dongs> you just said DMA was for gpio, waht does the timer have to od wiht it
2014-07-11T16:58:11 < slte> Hi all
2014-07-11T16:58:17 < slte> I am working on a bootloader
2014-07-11T16:58:45 < slte> and I need an extra sector in front of my interrupt vector table
2014-07-11T16:58:55 < dongs> why
2014-07-11T16:59:02 < twixx> dongs: timer (upd, ch1, ch2) triggers dma to write memory stuff to gpio->bsrr
2014-07-11T16:59:02 < slte> I am using openBlt
2014-07-11T16:59:34 < slte> does anyboydy know how should I modify my linker script?
2014-07-11T16:59:40 < dongs> twixx: yes, sure. so that works. if you arent getting it from other timer then you didnt enable it?
2014-07-11T16:59:56 < dongs> slte: writing your own bootloader is so trivial, why use something ugly and overengineered
2014-07-11T17:00:32 < twixx> dongs: i am reading about bitbending now.. nice stuff
2014-07-11T17:00:42 < slte> I am adding the new sector and when the downloaindg to flash completes the stack pointer is inittialised and the reset handler are positioned to right adress as I see from my map file
2014-07-11T17:00:50 < twixx> both timers are endabled and configured the same way
2014-07-11T17:00:53 < slte> but even so , I crashes
2014-07-11T17:01:00 < slte> it crashes
2014-07-11T17:01:29 < slte> if  something sounds familiar anybody
2014-07-11T17:03:27 < qyx_> of course, i heard "bootloader" in the past
2014-07-11T17:04:54 < twixx> dongs: thx. when you say it should work - i will check for bugs.
2014-07-11T17:09:36 < slte> how could I debug what exaclty happens when the address of the reset handler is called ?

2014-07-11T17:13:21 < dongs> if you wanna debug, lunix + gdb is probably not the most recommended combo
2014-07-11T17:13:33 < zyp> you could trap the reset, which would essentially be a breakpoint placed just before the first instruction of the reset vector is executed
2014-07-11T17:14:00 < zyp> not sure how you do that in a generic way, with blackmagic you can set it with the vector_catch command
2014-07-11T17:14:22 < zyp> you could possibly also set a normal breakpoint on the reset handler

2014-07-11T17:20:54 < dongs> why dont you load the bootloader .elf instead of your app?

2014-07-11T17:27:38 < zyp> you have tried what?
2014-07-11T17:28:05 < zyp> setting a breakpoint on the reset vector?
2014-07-11T17:28:21 < zyp> did you have the booloader symbols or the application symbols loaded when you tried that?

2014-07-11T17:32:41 < slte> yeah
2014-07-11T17:33:07 < zyp> yeah what
2014-07-11T17:33:12 < slte> I have downloaded the application in flash
2014-07-11T17:33:22 < slte> and then the bootloader as last step
2014-07-11T17:33:35 < slte> must do reset
2014-07-11T17:33:42 < slte> and before that
2014-07-11T17:34:05 < slte> has to map the vector table and the reset function
2014-07-11T17:34:47 < slte> so that after the reset my application starts nad not again the bootloader

2014-07-11T17:38:28 < slte> here is the function

2014-07-11T17:38:34 < slte> part of openblt
2014-07-11T17:39:01 < zyp> wat
2014-07-11T17:39:07 < dongs> ^^^^
2014-07-11T17:39:14 < zyp> what's up with 0x1FFFFF80?
2014-07-11T17:39:20 < dongs> thats hwawt i was thinking
2014-07-11T17:39:30 < slte> offset for the register
2014-07-11T17:39:54 < dongs> it ands with 1fffblah
2014-07-11T17:40:03 < dongs> not sets to it
2014-07-11T17:40:09 < dongs> duno man just write your own shit
2014-07-11T17:40:16 < dongs> isnt openblt some bloated crap that supports like AVR and shit
2014-07-11T17:40:32 < zyp> it's pointless
2014-07-11T17:40:34 < dongs> its like ~20 lines of code to do a functional bootloader on cortex -m3/4
2014-07-11T17:41:14 < zyp> if the value you're trying to set isn't properly aligned already, it's not like masking will make it properly aligned
2014-07-11T17:41:19 < dongs> heh
2014-07-11T17:41:29 < dongs> and isnt offset just some small number
2014-07-11T17:41:37 < dongs> i.e. how much to add to 0x80xxxxxx

2014-07-11T17:42:05 < slte> yeah and the allignment has change according to my sector size or what
2014-07-11T17:42:05 < dongs> my trashy bootloader starts at 0x3000
2014-07-11T17:42:13 < dongs> slte: what procesosr?
2014-07-11T17:42:41 < slte> stm32f103
2014-07-11T17:43:14 < slte> without the extra sector in front it works
2014-07-11T17:43:18 < zyp> required alignment doesn't have anything to do with sector size
2014-07-11T17:43:20 < slte> with it it crashes
2014-07-11T17:43:23 < dongs> what "extra sector"
2014-07-11T17:43:33 < dongs> you needto have your bootloader at start of flash
2014-07-11T17:43:35 < dongs> duhr
2014-07-11T17:43:50 < dongs> well, you COULD not have it at start but hten it gets super retarded
2014-07-11T17:43:52 < slte> I have in linker one extra section in fron of the apllication code
2014-07-11T17:43:54 < dongs> as you have to jump to somewehre else etc
2014-07-11T17:44:07 < dongs> (but you still need one page with vectors there)
2014-07-11T17:44:28 < dongs> slte: yeah so? why does that matter
2014-07-11T17:44:52 < dongs> bl|anycrapyouwant|app
2014-07-11T17:45:04 < dongs> as long as your bl sets vtor to app vectors, theres no problem?
2014-07-11T17:45:11 < zyp> slte, wait
2014-07-11T17:45:22 < zyp> do you have application code first, then bootloader?
2014-07-11T17:45:40 < dongs> or wait, its the app that sets vtor so wahtever. shit just works.
2014-07-11T17:45:45 < zyp> or bootloader first then application?
2014-07-11T17:45:56 < slte> no bootloader  and then space and the my section and then my code
2014-07-11T17:46:01 < dongs> i *think* he has wat i said, ^ ya that
2014-07-11T17:46:06 < zyp> ok
2014-07-11T17:46:18 < zyp> and it works with extra sector between, but not without?
2014-07-11T17:46:36 < zyp> if so, it sounds like part of your application is erased when you're flashing bootloader
2014-07-11T17:46:56 < slte> without works, with boom
2014-07-11T17:46:58 < zyp> which you'd solve by loading bootloader before application

2014-07-11T17:55:43 < dongs> this is in your app?

2014-07-12T08:53:01 < rewolff> ds2: ADC impedance would be "easy" if it was constant-resistance-to-ground. The problem is that if the last conversion was a conversion of a "high" voltage, you're effectively getting an impedance-to-that-voltage situation.

2014-07-12T09:31:27 < rewolff> Sorry. My IRC client doesn't show dates, and it seems to sometimes get "stuck" in the past instead of scrolling....
2014-07-12T09:32:08 < rewolff> I interpreted the time as about 4 hours ago.
2014-07-12T09:32:19 < upgrdman> fine with me :) i think you answered one of my questions a day after i asked. was glad to have an answer.
2014-07-12T09:33:18 < upgrdman> but while on the adc topic: could an adc not short it's sampling cap to ground between samples to get a more contact impedence?
2014-07-12T09:33:33 < upgrdman> s/contact/constant
2014-07-12T09:34:50 < rewolff> (on a forum I follow we're having a discussion about "old" questions. You get a warning when you answer to a thread that is "old" but then the thread gets "rejuvenated" and you don't get the warning anymore.... . I answered a question yesterday asked 12 years ago.... )
2014-07-12T09:35:54 < rewolff> Yeah, that would help for repeatability. But it costs power if you sample similar voltages on adjacent channels (or don't switch channels at all). I guess they offload the problem to the hardware guys by telling you to use a low-enough impedance on your signal.

2014-07-13T01:55:40 < gxti> which means A) it's too weird for -ffunction-sections to work and B) it doesn't matter as much anyway

2014-07-14T08:43:37 < dongs> .The AudioStream is like no other device on the market for a lot of reasons, but the clarity of the sound is the most important feature even beyond the freedom you will get with it. I have spent countless hours finding ways to eliminate Dirty Power, which is the major contributor to the static in the cheap products you can find at the .big box stores..

2014-07-14T12:39:28 < madist> I wish python allowed {} to be used interchangeably with tabs. Its the only problem I have with python.
2014-07-14T12:39:47 < jpa-> is your tab key broken or why?
2014-07-14T12:39:54 < __rob2> well then thats used for a dictionary
2014-07-14T12:39:58 < __rob2> so it would all get a bit messy
2014-07-14T12:40:01 < madist> I just can't "see" blocks as indentation.
2014-07-14T12:40:15 < __rob2> its a bit frustrating when you have spaces in 1 ide and tabs in the other

2014-07-14T15:35:58 < dongs> define "good"
2014-07-14T15:35:59 < Laurenceb_> ive got a roving networks rn-42
2014-07-14T15:36:04 < Laurenceb_> i need to connect to it
2014-07-14T15:36:07 < dongs> im about to make some board with it
2014-07-14T15:36:13 < Laurenceb_> interesting
2014-07-14T15:36:17 < dongs> but its some chink shit
2014-07-14T15:36:25 < Laurenceb_> it seems to ship in keyboard mode or something stupid
2014-07-14T15:36:35 < Laurenceb_> dunno how to get it out of keyboard mode
2014-07-14T15:37:49 < Thorn> iirc dony has bluetooth experience
2014-07-14T15:38:39 < Laurenceb_> it keeps refusing rfcomm connections
2014-07-14T15:39:00 < Laurenceb_> maybe i can connect in another mode and force it to reset
2014-07-14T15:39:04 < Laurenceb_> dunno how this works
2014-07-14T15:39:33 < Laurenceb_> modules from sparkfun are fine, digikey ones are weirdly configured
2014-07-14T15:40:24 < Steffanx> Can you repeat that Laurenceb_?
2014-07-14T15:40:41 < Steffanx> "modules from sparkfun are fine", Laurence Blaxter 2014
2014-07-14T15:40:49 < Laurenceb_> wut
2014-07-14T15:41:06 < Laurenceb_> overpriced, but at least they have the right firmware
2014-07-14T15:41:15 < jpa-> often there is a separate pin on the module that puts it in config mode, and after that you can send commands through the RS232
2014-07-14T15:41:36 < Laurenceb_> hmm
2014-07-14T15:41:43 < Laurenceb_> thats not going to be possible
2014-07-14T15:41:54 < Laurenceb_> the modules are all reflowed onto pcbs now
2014-07-14T15:42:35 < Laurenceb_> is there a bluetooth daemon log somewhere with more debug info?
2014-07-14T15:42:52 < jpa-> i would expect a digikey module to come with a proper datasheet and info on default config?
2014-07-14T15:43:22 < jpa-> wireshark can capture bluetooth IIRC
2014-07-14T15:44:22 < Laurenceb_> jpa-: according to digikey its just a rn-42
2014-07-14T15:44:24 < Laurenceb_> but they lie
2014-07-14T15:44:35 < Laurenceb_> its in keyboard mode or something weird

2014-07-14T15:45:39 < twixx> hey guys. i try to use TIM1_UP, TIM1_CH1-4 as requests for DMA1 (DMA Channels 2-6 rm0273) on STM32F103. it is only working for TIM1_UP, TIM1_CH3, TIM1_CH4. i get no transmission complete interrupts for the other ones. configuration for every channel is identical

2014-07-14T15:52:29 < tkoskine> Laurenceb_: Is the UART working? http://ww1.microchip.com/downloads/en/DeviceDoc/bluetooth_cr_UG-v1.0r.pdf seem to explain how to control the module via UART.
2014-07-14T15:53:18 < Laurenceb_> tkoskine: i cant access the UART
2014-07-14T15:57:11 < tkoskine> You are probably out of luck then.
2014-07-14T15:58:08 < Laurenceb_> funtimes
2014-07-14T15:58:18 < Laurenceb_> going to have to modify a ton of board
2014-07-14T15:58:24 < Laurenceb_> *boards
2014-07-14T15:59:43 < Laurenceb_> theres got to be some way to force rfcomm mode
2014-07-14T16:02:00 < tkoskine> UART command S~,0 sets profile to SPP, although it should be default.
2014-07-14T16:02:49 < tkoskine> SA2 command turns on 'just works' mode, which allows "easy no questions asked" pairing.
2014-07-14T16:03:01 < tkoskine> Err, SA,1 even
2014-07-14T16:03:32 < Laurenceb_> yeah, easy with usart access

2014-07-14T16:04:08 < tkoskine> SA,2 - yet another correction :) - SA,1 is default and sets some sort of SPP keyboard I/O mode.

2014-07-14T19:25:21 < jpa-> Steffanx, dongs: IIRC the ADC sampling capacitance is 50pF or so; so for 1% precision, 5000pF or 5nF should be enough; i'd make it 100nF or so
2014-07-14T19:26:01 < jpa-> the input impedance is just some value calculated at some samplerate

2014-07-14T20:38:36 < PaulFertser> Laurenceb_: the low-level command is "rfcomm" and I guess your distro has some way to call it appropriately for all devices listed in the config.
2014-07-14T20:39:35 < PaulFertser> Laurenceb_: the high-level way would be to use some gui like KDE's bluetooth control or blueman. Alternatively, you can issue dbus calls to bluetoothd from python or whatever.

2014-07-15T08:09:53 < zyp> better than not having enough room
2014-07-15T08:10:42 < dongs> it was originally like 130x100 or someshit. i told htem to cut it in half (since thats wehre mounting holes ended)

2014-07-15T08:36:37 < ds2> that's why you use a ECAD package that integrates with your MCAD
2014-07-15T08:38:27 < jpa-> ds2: that does not solve the issue of parallelizing pcb design and case design
2014-07-15T08:38:52 < jpa-> i doubt the problem was in transferring the info, just a question of order in which things were designed
2014-07-15T08:39:15 < ds2> that doesn't change that
2014-07-15T08:39:34 < ds2> still design it at the same time but use the MCAD to verify things fit reasonably well before starting fabrication
2014-07-15T08:40:45 < dongs> um, ds2, yeah, the problem isnt about fitting shit or not
2014-07-15T08:40:51 < dongs> case was designed long time ago
2014-07-15T08:40:56 < dongs> and is actually made etc.
2014-07-15T08:41:25 < ds2> if you are recycling cases....
2014-07-15T08:41:48 < dongs> not my problem :)
2014-07-15T08:42:00 < jpa-> they just designed *and* manufactured the case first - yes, it is a bad idea, which was quite much dongs' point :)
2014-07-15T08:42:20 < dongs> i can probly use all that empty space to fit a bigger battery in there anyway
2014-07-15T08:57:56 < ds2> dongs, have you done 0.65mm BGAs using your little fire starter oven?

2014-07-15T10:35:30 < zyp> so all they have to do is ship you a brick?
2014-07-15T10:36:04 < jpa-> or rather, give a tracking code for some totally unrelated package
2014-07-15T10:43:38 < dongs> jpa, it shows destination country and shit.
2014-07-15T10:44:10 < dongs> they would have to find a tracking that was shipped to japan aroudn same time, seems kinda pointless.
2014-07-15T10:45:11 < jpa-> depends on seller, if they are a large one they'll have many packages leaving for japan each day

2014-07-16T06:49:24 < dongs> lol @ wasting 400 units
2014-07-16T06:49:31 < dongs> because having no fucking clue, no doubt
2014-07-16T06:51:04 < dongs> We are extremely sorry about the bad news in the most recent update.
2014-07-16T06:51:04 < dongs> The issue with the 400 units resides in a small unexpected problem with the micro-USB port. The good news is that these 400 units are not completely wasted; they might be reused in a second production run, which may occur very soon (sooner than October, because we already have all the components on the bill of materials for these units).
2014-07-16T06:51:09 < dongs> loooooooooooooooool wat
2014-07-16T06:51:14 < dongs> unxpected problem with microusb port???
2014-07-16T06:51:26 < dongs> what "problem" could it be that they'd have to scrap 400 units?
2014-07-16T06:51:42 < dongs> and lol @ reuse, wat are tehy gonna do, take out and reball qualcom SoC?
2014-07-16T06:52:30 < dongs> How is having 100 backers going to grab the 100 units at Best Buy going to help with "testing the market"? Do Neptune not have any clue how market research works? All this does is add an extra step to the acquirement process for that 100 backers, inconveniencing them by forcing them to go to the store to get their Pines and then wait for reimbursement of the purchase price...
2014-07-16T06:52:36 < dongs> ahahah
2014-07-16T06:52:38 < ossifrage> dongs, that thing is insanely huge
2014-07-16T06:52:43 < dongs> ossifrage: it fucking is
2014-07-16T06:52:53 < dongs> ossifrage: its just a shitty chink landfill android in a HUGE case with a HUGE wristband
2014-07-16T06:53:36 < dongs> and they took 600k from retards and blew through it, backpedaled on all the "features" they were going to add, and now its back to original chinese shit of just being a huge ugly assdroid phone running 4.0 without play store or any future ugprades
2014-07-16T06:53:45 < ossifrage> is that a <50% yield, how many where they making to have 400 drop out?
2014-07-16T06:53:53 < dongs> ossifrage: 2k
2014-07-16T06:54:59 < dongs> or maybe 2.5k
2014-07-16T06:55:08 < dongs> 1 - We will ship to backers and pre-orderers; not prioritized by country (i.e. US and Canada), but rather by date of order. A little less than 2000 backers, the ones who ordered first, would receive their Pines immediately.
2014-07-16T06:55:44 < ossifrage> that is some shitty yield that couldn't be fixed by rework
2014-07-16T06:56:16 < dongs> there are only so many "problems" that can occur with a microUSB socket
2014-07-16T06:56:20 < dongs> and all CAN be fixed by rework.

2014-07-16T06:58:20 < ossifrage> smarty ring looked like either a scam or some folks way, way, way in over their head
2014-07-16T07:00:06 < ossifrage> But I honestly don't understand why people would give money to a flexible-funding hardware project on indiegogo
2014-07-16T07:00:26 < ossifrage> You would be better off flushing your money or buying lottery tickets
2014-07-16T07:01:05 < SlaveToTheSauce> i am all for the time-tested hookers and blow budget
2014-07-16T07:02:17 < ossifrage> the one thing that I was somewhat impressed with with the smarty think is that they are trying to wirebond led dice to the pcb
2014-07-16T07:02:50 < ossifrage> that is really brave, because the yield doing that could really suck hard
2014-07-16T07:05:52 < SlaveToTheSauce> ya and sounds pretty fragile too, even with the flexpcb inside a rigid container
2014-07-16T07:06:25 < SlaveToTheSauce> unless they coat it with clear epoxy after it's bent to the right diameter or something
2014-07-16T07:07:52 < ossifrage> SlaveToTheSauce, if the PCB is rigidly mounted then the bond wires should be okay
2014-07-16T07:08:08 < ossifrage> as long as there isn't something to rub against them
2014-07-16T07:08:20 < SlaveToTheSauce> well they presumably do the bonding with it flat right?
2014-07-16T07:08:25 < SlaveToTheSauce> and then curl it up to go in the housing
2014-07-16T07:08:51 < ossifrage> the photos they posted didn't look like they where doing it on flex, but rigid
2014-07-16T07:09:13 < ossifrage> I didn't understand that, maybe the photo is just some random LED module and has nothing to do with the project :-)
2014-07-16T07:09:15 < SlaveToTheSauce> okay i was under the impression the whole pcb was flexible
2014-07-16T07:09:32 < SlaveToTheSauce> cause the ring seems pretty circular
2014-07-16T07:09:46 < SlaveToTheSauce> but who knows, what they're assembling now probably looks nothing like the photos they've shown
2014-07-16T07:09:48 < ossifrage> I'd imagine things like the BLE chip and the LED drivers would want to be on rigid (can be very thin)
2014-07-16T07:10:07 < ossifrage> maybe with the proper use of underfill you can get away putting a small chip scale BGA on flex
2014-07-16T07:10:26 < ossifrage> but you are effectively creating a rigid section
2014-07-16T07:10:33 < SlaveToTheSauce> right

2014-07-16T07:11:12 < SlaveToTheSauce> welp i guess we'll see eventually when they get their shit together. or perhaps they're sitting on a beach somewhere with 300k in a briefcase
2014-07-16T07:12:01 < ossifrage> The LED package acts as a diffuser and a lens, so having bare die will have some interesting side effects
2014-07-16T07:12:32 < ossifrage> also they need to be really careful with the placement to keep the grid regular or it will look strange
2014-07-16T07:13:11 < ossifrage> 300k would go a long way in chennai
2014-07-16T07:16:11 < ossifrage> oh, they actually did 2 indygogos, one for $298k and a second for $102k
2014-07-16T07:17:42 < ossifrage> I wonder what credit card companies policies are for crowd funding?
2014-07-16T07:18:00 < SlaveToTheSauce> same window for chargebacks as anything else i think
2014-07-16T07:18:21 < SlaveToTheSauce> basically by the time it comes to light that it's a scam or they're incompetent or whatever, you're screwed
2014-07-16T07:18:30 < SlaveToTheSauce> and indiegogo doesn't give a shit afaik
2014-07-16T07:18:42 < SlaveToTheSauce> ks is a little better about dealing with overt fraud
2014-07-16T07:18:51 < ossifrage> I actually think you could build a 'smarty watch', maybe not in metal, but tech wise it is doable
2014-07-16T07:18:59 < ossifrage> the biggest suck will be battery life
2014-07-16T07:19:37 < SlaveToTheSauce> yeah switch the display to e-ink for a pretty big boost there

2014-07-16T07:20:15 < SlaveToTheSauce> and really in a watch you could probably bet away with a thickened section for an extra 150mAh or something
2014-07-16T07:20:18 < SlaveToTheSauce> get away*
2014-07-16T07:20:26 < ossifrage> they have a better chance of getting the discrete LED display to work
2014-07-16T07:20:46 < ossifrage> finding an e-ink display in the right formfactor that is flexible will be really hard
2014-07-16T07:21:56 < SlaveToTheSauce> several rigid ones might work
2014-07-16T07:22:05 < SlaveToTheSauce> and really it doesn't need to be all that round does it
2014-07-16T07:22:11 < SlaveToTheSauce> a friend of mine wears his ks pebble every day, loves the damn thing
2014-07-16T07:23:24 < ossifrage> the sharp memory display in the pebble is some interesting tech
2014-07-16T07:23:45 < ossifrage> it is low power, not zero-power, you still have to refresh it

2014-07-16T07:42:35 < ossifrage> dongs, I get a kickout of drop-kicker.com (wish he posted more often, but his stuff tends to be well researched)
2014-07-16T07:44:04 < dongs> yeah
2014-07-16T07:44:13 < dongs> i keep reloading it daily and theres nothign new :(
2014-07-16T07:44:40 < ossifrage> the thing he did on the smarty ring was really well done (and that energy harvesting tag)
2014-07-16T07:45:15 < dongs> i duno if he used my email but the parts research and stuff I blogged in here before mailing him about it
2014-07-16T07:45:31 < dongs> i matched that nrf thing, and the allegro led drivers because I used them in something else before
2014-07-16T07:45:45 < dongs> nrf thing by pinout cuz they posted pcb layout pics
2014-07-16T07:46:01 < dongs> but i think a few people contacted him around same time with same/similar stuff
2014-07-16T07:46:10 < dongs> cause it wasnt exactly hard to figure out
2014-07-16T07:46:44 < dongs> but yea ifind shit was great.

2014-07-16T07:57:15 < dongs> oh he did credit me in the smarty article
2014-07-16T07:59:30 < ossifrage> Why do people keep investing in those tags, for the most part they suck hard
2014-07-16T07:59:50 < dongs> i think they just suck, and people suck
2014-07-16T07:59:53 < dongs> so its a perfect match
2014-07-16T08:00:22 < ossifrage> and they want $30 for this one
2014-07-16T08:00:37 < ossifrage> the bom for that thing is like <$5

2014-07-16T12:47:13 < karlp> you can read it bytewise, but the stdperiph lib stuff at least had warnings about trying to write bytewise

2014-07-16T15:26:55 < Evidlo> I read that the STM32 family can only sink about 25mA.  Does this mean if I'm driving a 7-segment display, I can only have one segment on per digit at a time?
2014-07-16T15:27:32 < jpa-> depends on how you drive it
2014-07-16T15:27:44 < timemob> yes. and if you're driving 7 segment you should really use some chip to help
2014-07-16T15:27:47 < jpa-> smart people use a FET or buffer chip to drive the common anode
2014-07-16T15:27:49 < Evidlo> Straight from the IO pins on the chip
2014-07-16T15:27:57 < Evidlo> the stm32
2014-07-16T15:28:24 < Evidlo> I keep that in mind on the first rev.
2014-07-16T15:28:50 < timemob> how many digits?
2014-07-16T15:28:55 < Evidlo> 4
2014-07-16T15:29:05 < Evidlo> Each with its own anode
2014-07-16T15:29:19 < timemob> you can use 16 bit led driver chip
2014-07-16T15:29:47 < Evidlo> Would that be smaller than 4 sot23 mosfets?
2014-07-16T15:29:52 < timemob> sink digits and put pfets on top 4 bits to switch high side
2014-07-16T15:30:22 < timemob> dunno but it would be a lot less I/o

2014-07-16T17:01:04 < PaulFertser> Have you seen this new push-and-shove router in KiCAD sponsored by CERN: http://www.youtube.com/watch?v=CCG4daPvuVI ?
2014-07-16T17:01:56 < Steffanx> isn't that semi-old?
2014-07-16T17:02:06 < Steffanx> They did releasea new footprint editor not?
2014-07-16T17:02:13 < Steffanx> *push
2014-07-16T17:02:49 < PaulFertser> http://www.ohwr.org/projects/cern-kicad/wiki Module editor released for testing
2014-07-16T17:03:00 < Steffanx> All i want is a proper kicad version for os x :P
2014-07-16T17:03:32 < Steffanx> but i understand that is "impossible" or they don't care enough because there a too few users
2014-07-16T17:03:46 < PaulFertser> Is using X clients really painful on OS X?
2014-07-16T17:04:25 < Steffanx> x? They use wxwidgets and there are issues with the implementation of the widgets that are used to draw the schematics etc.
2014-07-16T17:05:23 < PaulFertser> That's talking about native widgets and Quartz, but what about just using an X server and regular widgets?
2014-07-16T17:05:29 < BrainDamage> wx is a bit different from other toolkits
2014-07-16T17:05:46 < BrainDamage> it has a thin-ish api, and then a wrapper around the native platform api
2014-07-16T17:06:02 < BrainDamage> which means that each platform has an unique set of bugs and problems
2014-07-16T17:06:03 < PaulFertser> Can't it be built around Gtk?
2014-07-16T17:06:12 < PaulFertser> on OS X I mean
2014-07-16T17:06:34 < BrainDamage> I don't remember, it's been few years since I last used it
2014-07-16T17:06:47 < BrainDamage> back then it was cocoa and carbon experimental ( or viceversa )
2014-07-16T17:06:54 < PaulFertser> Also, Gtk+ has Quartz backend on its own, so if wxwidgets are linked against gtk and gtk is using quartz backend, it might work, no?
2014-07-16T17:07:39 < BrainDamage> looks like it's possible: http://wiki.wxpython.org/wxGTK%20on%20Mac%20OSX
2014-07-16T17:08:13 < BrainDamage> altough I wonder what set of new quirks it'll make ...
2014-07-16T17:08:14 < Steffanx> hmm
2014-07-16T17:08:52 < Steffanx> Nor sure if it's really worth the hassle
2014-07-16T17:11:02 < BrainDamage> mmm, kicad's page now states "KiCad on the Mac OS X is still  experimental, but most functionality works. Only the viewport algorithm  is slow and the about dialog is broken." perhaps it got better, or is it an understatement of the working status?
2014-07-16T17:12:01 < Steffanx> no, no understatement. It is exactly as they say it is.
2014-07-16T17:12:10 < Steffanx> it works, but it is slow.

2014-07-17T05:02:51 < zyp> the one with the repaired boards
2014-07-17T05:02:58 < dongs> huh really
2014-07-17T05:03:06 < zyp> gxti, yeah, that's it
2014-07-17T05:03:19 < dongs> oh uhh
2014-07-17T05:03:20 < dongs> asking
2014-07-17T05:03:32 < zyp> if you have a project that warrants two f4s for some reason, RMII might be a good way to interconnect them
2014-07-17T05:04:00 < gxti> maybe you could even find a nice switch IC and interconnect a whole bunch
2014-07-17T05:04:17 < dongs> wow i think you've got a perfect dickstarter plan going
2014-07-17T05:04:38 < gxti> i thought that required a host port, but i also thought you couldn't crosslink two stm32s and apparently you can so maybe it'll work :p
2014-07-17T05:05:53 < zyp> RMII is pretty symmetric
2014-07-17T05:06:42 < zyp> apart from MDIO/MDC which you don't need since there's no PHY to configure and clock which you can supply from a common source to both
2014-07-17T05:06:50 < zyp> or possibly from one to the other
2014-07-17T05:07:08 < dongs> oh
2014-07-17T05:07:10 < dongs> its deliverre,d zyp
2014-07-17T05:07:15 < dongs> on jul 4th
2014-07-17T05:07:17 < dongs> lo
2014-07-17T05:07:28 < dongs> wtf only took 3 days
2014-07-17T05:07:54 < zyp> so you gave me the wrong number?
2014-07-17T05:07:57 < dongs> yes
2014-07-17T05:08:02 < dongs> i just /noticed you correct one
2014-07-17T05:08:54 < zyp> wat
2014-07-17T05:08:54 < dongs> loooks like the chick who messaged it to me misplaced 3 and 6
2014-07-17T05:09:01 < dongs> in 3rd digit
2014-07-17T05:09:05 < dongs> wat wat?
2014-07-17T05:09:09 < zyp> looks like somebody received it and signed as me
2014-07-17T05:09:12 < dongs> yes
2014-07-17T05:09:19 < dongs>  < dongs> its deliverre,d zyp
2014-07-17T05:10:42 < zyp> I just didn't expect anyone to be able to receive the delivery, but that's fine
2014-07-17T05:10:55 < zyp> guess it was my neighbor :p

2014-07-17T05:44:22 < upgrdman> need pull-down resistors on my ADC pins. doesn't seem to work. do the internal pull ups/downs not work whan a gpio is set to analog mode?
2014-07-17T05:44:33 < upgrdman> external resistors works as expected
2014-07-17T05:48:24 < GargantuaSauce> f0?
2014-07-17T05:49:21 < upgrdman> ya
2014-07-17T05:50:07 < GargantuaSauce> ref manual section 8.3.12
2014-07-17T05:50:17 < GargantuaSauce>  The weak pull-up and pull-down resistors are disabled
2014-07-17T05:51:03 < GargantuaSauce> i think they're still enabled on one of the other lines, cant remember
2014-07-17T05:51:26 < upgrdman> damn it
2014-07-17T05:52:08 < upgrdman> i wonder if the adc will still read if i set to open-drain/output low/enable pull-up
2014-07-17T05:52:14 < upgrdman> will try :(
2014-07-17T05:52:26 < upgrdman> err output high
2014-07-17T05:52:43 < GargantuaSauce> i suspect not
2014-07-17T05:53:06 < GargantuaSauce> i think the block diagram they provide is kind of misleading when it comes to how the af multiplexing actually works
2014-07-17T05:53:34 < dongs> wont
2014-07-17T05:53:38 < dongs> yeah dont leave ADC inputs floating
2014-07-17T05:53:45 < dongs> i did that before and it just reads random trash
2014-07-17T05:54:10 < upgrdman> ya
2014-07-17T05:54:25 < upgrdman> i wonder why they would disable pull ups/down
2014-07-17T05:54:38 < dongs> why woudlnt they
2014-07-17T05:54:47 < dongs> you wanna read vcc or gnd???
2014-07-17T05:55:25 < GargantuaSauce> i guess if it had a well-defined impedance you could use it as a voltage divider
2014-07-17T05:55:33 < GargantuaSauce> but yeah it doesn't.
2014-07-17T05:55:40 < upgrdman> reading a four wire resistive touch panel. if no touch, the adc input will float
2014-07-17T05:55:57 < GargantuaSauce> yeah sounds like a very weak external pulldown is in order
2014-07-17T05:56:24 < upgrdman> ya. but i wonder why they prevent you from using the internal ones. im sure its a rare use case, but still
2014-07-17T05:57:00 < GargantuaSauce> probably because the mux actually sits in front of them to minimize noise or whatever
2014-07-17T05:57:20 < GargantuaSauce> even with them off there'd still be some leakage
2014-07-17T05:57:28 < dongs> dickage
2014-07-17T05:57:33 < dongs> upgrdman: why do you always do shit the dumb way
2014-07-17T05:57:43 < dongs> a SPI resistive touchscreen driver is like free
2014-07-17T05:57:46 < dongs> on any china lcd
2014-07-17T05:57:53 < GargantuaSauce> he has yet to advance to protroll rank
2014-07-17T05:58:21 < upgrdman> dongs: because the lcd i bought didnt have one. and yes, i have used SPI touch controllers
2014-07-17T05:58:44 < upgrdman> and besides, why not? it's not like the IC is cheaper than four traces on a pcb
2014-07-17T06:01:58 < GargantuaSauce> so what are you building anyway
2014-07-17T06:03:15 < upgrdman> im redesigning my servo tester and making it into a general tool and dev board. porting my spectrum analyzer code to it, so i now have a 2.4GHz SpecAn for $1.90 added BOM cost ... plan to add a bunch of other shit, because why not.
2014-07-17T06:04:05 < upgrdman> doing current sensing for four servo ports, datalogging, even doing bluetooth because fuck it why not.
2014-07-17T06:04:13 < GargantuaSauce> sweet
2014-07-17T06:04:30 < upgrdman> maybe get around to writing an assdroid app to graph current, voltage, etc.
2014-07-17T06:05:04 < upgrdman> my old specAn: https://www.youtube.com/watch?v=kCoucYFKTFY&list=UU_vO52hFzjMd2bPQA5AaHhg
2014-07-17T06:05:09 < dongs> sounds like a dickstarter dream
2014-07-17T06:05:14 < dongs> just add arduino compatible headers
2014-07-17T06:05:18 < upgrdman> i know. but im just doing it for me.
2014-07-17T06:05:27 < upgrdman> not trying to con a bunch of fuckers
2014-07-17T06:05:57 < dongs> dats some microwafve
2014-07-17T06:06:09 < upgrdman> ya i know
2014-07-17T06:06:17 < upgrdman> hopefully i dont end up sterilizing myself
2014-07-17T06:07:28 < GargantuaSauce> i think microwaves are allowed to leak something like 10W
2014-07-17T06:07:51 < dongs> perfect charger for iFind WeTag
2014-07-17T06:07:53 < dongs> !!!

2014-07-17T06:25:23 < GargantuaSauce> may as well use a lm2560 chinamodule

2014-07-17T06:29:06 < GargantuaSauce> yeah
2014-07-17T06:29:12 < GargantuaSauce> if it were a linear one i could understand
2014-07-17T06:29:21 < GargantuaSauce> but it's a 5A ubec, no way that's not a buck converter
2014-07-17T06:30:03 < dongs> you mean its not just 5 LM7805's in parallel???
2014-07-17T06:33:02 < emeb_mac> mmm... toasty
2014-07-17T06:34:03 < GargantuaSauce> well
2014-07-17T06:34:11 < GargantuaSauce> i can't say i would find that too surprising
2014-07-17T06:35:46 < GargantuaSauce> it's got metal tape under the heatshrink presumably to keep it from shitting rf all over the place
2014-07-17T06:35:55 < upgrdman> i look at china esc's at work all the time. it's "nice" to see the ghetto shit they do. "shit, one 7805 doesn't cut it. and we're not going to change the pcb. fuck it... lets stack THREE on top of each other, and let's skip any sort of heatsinking/spreading..."
2014-07-17T06:36:22 < upgrdman> they also do that with current shunts in the cheap watt meters
2014-07-17T06:36:36 < GargantuaSauce> oh man metal tape with kapton on the other side, i want a roll of this
2014-07-17T06:36:46 < GargantuaSauce> did not know that was a thing
2014-07-17T06:36:58 < upgrdman> ya
2014-07-17T06:37:15 < upgrdman> im guessing its cheaper, or just using whats in stock/available in walking distance
2014-07-17T06:37:37 < GargantuaSauce> i imagine its intended use is protecting parts in an oven
2014-07-17T06:37:40 < upgrdman> i see that shit all the time. it's rare not to, when looking at the no-name junk
2014-07-17T06:37:57 < upgrdman> oh, the tape. nm

2014-07-17T16:30:53 < Steffanx> twixx, you can toggle it at 50MHz twixx
2014-07-17T16:32:33 < Garandor> Hi guys. I thought the new cube libs had startup code and ldscripts for every MCU of their family, but after downloading Cube_FW_F2 i only find ldscripts for F217IG MCUs. Can those be used with the other F2 family chips e.g. 207ig too?
2014-07-17T16:33:21 < Garandor> and if so, does this ldscript transitivity follow some kind of rule?
2014-07-17T16:33:28 < emeb_mac> probably not much difference between F207 and F217.
2014-07-17T16:34:06 < emeb_mac> changing flash/ram amounts in the ldscript is easy - that's the main thing that matters.
2014-07-17T16:34:32 < Garandor> yes - but doing this manually sucks
2014-07-17T16:34:53 < Garandor> if there were 1 script per MCU, autoselection would be possible

2014-07-17T16:39:23 < john_____> which are the cmos pins and which are ttl?
2014-07-17T16:39:41 < claude> also in the datasheet
2014-07-17T16:39:45 < claude> ;)
2014-07-17T16:39:51 < john_____> there is 2.7V < VDD < 3.3
2014-07-17T16:40:09 < john_____> so high is between 2.7V and 3.3V?
2014-07-17T16:40:15 < claude> nope
2014-07-17T16:40:22 < claude> depends on the load
2014-07-17T16:40:44 < john_____> ok let's sit down and talk
2014-07-17T16:40:50 < john_____> if I get a multimeter
2014-07-17T16:41:04 < john_____> and put let's say pin 15 to high
2014-07-17T16:41:40 < Steffanx> if nothing is attached it will probably go somewhere close to VDD
2014-07-17T16:42:45 < claude> *if* it is a usual multimeter with e.g. 1Mohm input impendance then  : Voh = VDD-0.4V (2.9V in your case , as your VDD is 3.3V)
2014-07-17T16:43:11 < Steffanx> a minimal of 2.9V that is.
2014-07-17T16:43:42 < Steffanx> *minumum
2014-07-17T16:43:46 < Steffanx> *minumum lol
2014-07-17T16:43:52 < john_____> oh I get it now
2014-07-17T16:44:11 < claude> yeah datasheet specifies the "min" value , so likeley over it . but if you go for relaibility then always use the worst case values ;)
2014-07-17T16:44:44 < john_____> so the worse case is I get 2.7V

2014-07-17T16:45:15 < claude> Vdd isn't a constant here :)
2014-07-17T16:45:48 < claude> VDD on the F4Disco is 3.3Vish , so take that as VDD
2014-07-17T16:46:16 < claude> then depening on the ammount of current the io pin sources or sinks you get the values from the table.
2014-07-17T16:46:35 < dongs> < Garandor> if there were 1 script per MCU, autoselection would be possible
2014-07-17T16:46:44 < dongs> its not like youre compiling for 20 different chips
2014-07-17T16:46:47 < dongs> edit it once and forget it
2014-07-17T16:46:54 < claude> e.g. when you source 20mA on the pin (e.g. an led) you will get (worst case) only VDD-1.3V out of it
2014-07-17T16:47:09 < claude> as high level
2014-07-17T16:48:32 < john_____> how much impedance does the base of a transistor have, or how much current flows?
2014-07-17T16:49:42 < claude> depends on the Hfe of the transistor and other parameters .... what do you want to switch with the transistor and what type of transistor?
2014-07-17T16:49:53 < trepidaciousMBR> The disco boards tend to be (annoyingly) 3.0V, unless you find the magic pointless diode and remove it :)
2014-07-17T16:50:12 < dongs> hmm FTDI has a 3x3 usb>uart
2014-07-17T16:50:26 < dongs> ohh exar is 3x3 but spendy
2014-07-17T16:50:46 < john_____> I would like to get from 3.3 V to 5 V
2014-07-17T16:51:14 < claude> 5V@1mA or 5V@1kA ?
2014-07-17T16:51:51 < john_____> i think it's 1mA
2014-07-17T16:52:19 < john_____> for arduino module they have 5 V as high state
2014-07-17T16:53:01 < claude> yeah well get a 10k base resistor and there you go :) if the signal looks horrible lower the value.... *OR* read up on basic EE ;)
2014-07-17T16:53:34 < Steffanx> No, that is not true. john_____ you have to read some AVR datasheet to find the REAL voltage for a "high" state.
2014-07-17T16:54:27 < claude> on AVR , thats around 12V i guess? right?
2014-07-17T16:54:45 < Steffanx> lol.
2014-07-17T16:56:34 < claude> john_____, if you want to send some signal from your stm32 to an arduino just connect the pins. AVRs are also CMOS level . but the other way around (AVR to STM32) you want to make sure the STM32 pin is 5V tolerant or you need some sort of level shifter (resistor divider,mosfet or logic gate etc etc)
2014-07-17T16:58:49 < john_____> I can't go other way around, because I have arduino module as 1637TM chip, which needs 5 V of VDD and
2014-07-17T16:59:19 < john_____> and voltage levels are 0 to 5 v
2014-07-17T16:59:53 < john_____> look for the datasheet for TM1637 chip
2014-07-17T17:00:02 < claude> do you have a datasheet url for that 1637TM thingy?
2014-07-17T17:00:39 < perole>  speaking of voltage dividers, anyone know at what frequencies the simple 2 resistor version no longer works?

2014-07-17T17:01:03 < perole> I need to scale down RGB video from about 3v -> 0.7v

2014-07-17T17:01:11 < john_____> i don't understand it
2014-07-17T17:01:20 < john_____> but hey you have google translate
2014-07-17T17:02:12 < claude> yeah me too , but anyhow : 高电平输入电压 VIH 0.7 VDD - VDD V -
2014-07-17T17:02:57 < john_____> what does it mean?
2014-07-17T17:02:59 < claude> 0.7 * VDD , your MT1637 VDD is 5V ?
2014-07-17T17:03:16 < claude> that interprets the chip as logical '1'
2014-07-17T17:03:16 < john_____> yes VDD is 5 V
2014-07-17T17:03:45 < claude> 3.5V is that , sooooo what to do :)
2014-07-17T17:04:18 < john_____> wait
2014-07-17T17:04:29 < john_____> so I need 3.5V but I have 3.3
2014-07-17T17:04:35 < claude> right
2014-07-17T17:04:46 < john_____> so transistor thing?
2014-07-17T17:05:35 < claude> do you want to use a gpio or dedicated io pin from the stm driving that thing?
2014-07-17T17:06:14 < john_____> just ordinary
2014-07-17T17:06:20 < john_____> as high and low
2014-07-17T17:06:26 < john_____> no I2C
2014-07-17T17:06:34 < john_____> or something else
2014-07-17T17:06:34 < claude> if gpio : pick a "5v tolerant pin" from the datasheet , switch the gpio into open drain mode add a e.g. 1k pullup to 5V . finished
2014-07-17T17:07:27 < claude> don't forget about the open drain , otherwise the signal will be still at 3.3V
2014-07-17T17:09:05 < john_____> wait, so you are telling me that gpio pin on stm32f4 can be more then 3.3V?
2014-07-17T17:09:14 < john_____> open-drain mode?
2014-07-17T17:10:47 < claude> yes but only if the pin is "5V tolerant" (look that up in the datasheet) and if you switch the gpio into open drain mode. then you can "pull" the the pin upto the "5V tolerant pin max io voltage" (or so....) specified in the datasheet

2014-07-17T17:21:53 < karlp> also, exar drivers were removed from the kernel :(
2014-07-17T17:23:25 < karlp> I think they might have changed fabs/process rather than any corners,
2014-07-17T17:23:38 < karlp> the newer ones are cheaper, need less external parts, and come in smaller packages, it's win all around

2014-07-17T17:24:11 < claude> john_____, https://www.flickr.com/photos/oskay/6794891988/ . now take the the SN7407 as your STM32's 5v tolerant pin , change the 12V to 5V
2014-07-17T17:24:17 < karlp> silabs cp210x shit is nice, but some of their parts use fucking OTP to change settings
2014-07-17T17:25:17 < john_____> ok thank you
2014-07-17T17:25:40 < john_____> can you look up in the datasheet which is a 5 V tolerant pin?
2014-07-17T17:25:45 < claude> john_____,  but tbh thats all basic EE stuff . how about reading up on that first?
2014-07-17T17:25:51 < claude> john_____, nope

2014-07-17T17:27:15 < john_____> so thank you

2014-07-17T17:28:06 < claude> so if you are a 'programmer' then you probably have read up on some topic before? it's the same in electronics , read , try to understand and then ask :)
2014-07-17T17:28:44 < claude> but you are asking right now for reading stuff up for you o_O

2014-07-17T22:52:36 < emeb> Sounds right to me.
2014-07-17T22:52:55 < emeb> I've used the cycle counter to guesstimate CPU loading.
2014-07-17T22:53:11 < emeb> sample it periodically from systick to get an interval in cycles
2014-07-17T22:53:56 < Xata> emeb: same trouble here, i had a thought, that my cpu freezes because it lacks cpu time. looks like this is not the case. pity.
2014-07-17T22:53:59 < emeb> also sample it @ start and end of a periodic process to determine the fraction of time that process runs
2014-07-17T22:54:22 < emeb> total time is delta from one start to next start
2014-07-17T22:54:40 < emeb> process time is delta from start to end
2014-07-17T22:54:51 < emeb> fraction is process time / total time
2014-07-17T23:01:32 < Xata> fraction is almost 0.76
2014-07-17T23:01:55 < Xata> emeb: this ain't good, i suppose. Because that's only one timer

2014-07-18T00:23:27 < Xata> emeb: strange thing. i have a timer, and a breakpoint on first line of the handler. i am measuring time between hits of that breakpoint and result vary. like, 50%, absolutely random
2014-07-18T00:24:06 < Xata> isn't timer has to be stable
2014-07-18T00:43:47 < GargantuaSauce> debugging isn't
2014-07-18T00:44:27 < GargantuaSauce> get rid of the breakpoint and make it toggle a pin and watch it with a LA or scope, and you'll see it's periodic
2014-07-18T00:45:42 < karlp> or, for people who love more software, and less probes, write the cycle count into a little circular buffer in memory, then just let it run, and pause the code, and print out the mem buffer
2014-07-18T00:46:23 < emeb> +1 for GPIO toggles
2014-07-18T00:46:32 < GargantuaSauce> ya sure. either way, don't make any assumptions about the timing of debugging operations
2014-07-18T00:46:36 < emeb> That's my 1st stop in any realtime debug
2014-07-18T00:47:05 < karlp> yeah, gpio toggling's pretty easy, nice to see any jitter too

2014-07-18T10:23:23 < john___> hello, i am that guy from yesterday
2014-07-18T10:23:29 < john___> i have one question
2014-07-18T10:24:09 < john___> if I set a pin on stm32f4 in open-drain mode, can I use it as output?
2014-07-18T10:24:35 < john___> so that I set the pin to "high"
2014-07-18T10:25:32 < john___> pin is connected to a pull up resistor which is connected to 5 V
2014-07-18T10:28:35 < jpa-> uh, of course?
2014-07-18T10:28:42 < jpa-> what else would open-drain mean?
2014-07-18T10:29:07 < jpa-> though make sure that it is a 5V-tolerant pin
2014-07-18T10:30:02 < john___> hmm
2014-07-18T10:30:17 < john___> open drain means sucking the current
2014-07-18T10:32:02 < jpa-> or not doing so.. and when you don't suck the current, it floats high?
2014-07-18T10:34:59 < john___> sorry i don't understand, when I put the pin to zero, the output is also zero, when I put to one, it's 5 V - 1.7

2014-07-18T10:43:56 < jpa-> john___: is it a 5V compatible pin? because if it is not, it will clamp to 3.3V (or whatever is your Vcc)
2014-07-18T10:45:18 < john___> it is 5 V tolerant pin
2014-07-18T10:45:57 < john___> that's what claude said
2014-07-18T10:45:59 < jpa-> if you remove the pull-up, what is the voltage then?
2014-07-18T10:46:09 < jpa-> well check yourself from datasheet
2014-07-18T10:47:41 < john___> Voltage levels for gpio pins on stm32f4 are low = 0 V and high = 3.3 V
2014-07-18T10:50:29 < madist> does it make sense to measure a CMOS output with no load ?
2014-07-18T10:50:34 < madist> it will always be VCC
2014-07-18T10:51:24 < john___> ok I understand now
2014-07-18T10:51:44 < jpa-> such crazy, much confusion
2014-07-18T10:51:59 < john___> does anyone uses IAR embedded workbench?
2014-07-18T10:53:49 < tkoskine> I use IAR EW for ARM/STM32.
2014-07-18T10:54:17 < tkoskine> Not willingly, though. :)
2014-07-18T10:56:15 < john___> do you programm in C? I programm in C, and I would like to know which standard uses for strings a.k.a table of charachters?
2014-07-18T10:56:47 < john___> ascii or utf-8 or utf-16?
2014-07-18T10:58:29 < tkoskine> In C, but I don't really deal with strings. Mostly with byte streams using uint8_t arrays.
2014-07-18T11:03:13 < john___> I have a problem sending a "char table[ ] = "hello" " via UART sending to another device
2014-07-18T11:03:37 < john___> i  send string "hello"

2014-07-18T11:05:44 < john___> is it because of unicode or ascii?
2014-07-18T11:05:48 < tkoskine> The problem could be pretty much anything from programming error to faulty hardware (connections).
2014-07-18T11:06:16 < tkoskine> But almost for sure, it is not related to unicode or encoding.
2014-07-18T11:06:17 < zyp> if the string gets reversed, it's pretty guaranteed a programming error
2014-07-18T11:06:26 < zyp> and completely unrelated to encoding
2014-07-18T11:07:39 < john___> maybe is then because of speed, I don't call sleep function

2014-07-18T11:17:00 < john___> How did you calculate how much resistance?

2014-07-18T12:08:38 < Claude> oh yes good point
2014-07-18T12:10:08 < PaulFertser> I think libopencm3 API is way better in this regard, you can't just forget e.g. that you need to care about the internal pulls.
2014-07-18T12:10:22 < PaulFertser> Because you can't call a function with a wrong number of arguments.
2014-07-18T12:10:56  * Claude makes a note : next time doing something with stm32 try libopencm3
2014-07-18T12:11:28 < PaulFertser> jpa-: in case of using ST library that might lead to confusing settings as well I'm afraid. But at least they would be consistent and not depend on subtle optimisation tricks.
2014-07-18T12:12:37 < jpa-> it could yeah, though in most cases the 0 settings are pretty sensible
2014-07-18T12:18:03 < PaulFertser> Is their "cube" or whatever is of better quality than stdperiphlibrary?

2014-07-18T12:24:57 < john___> Another thing about the pin, which is configured to open-drain mode
2014-07-18T12:25:11 < john___> it's not going to be only output
2014-07-18T12:25:21 < john___> but also input
2014-07-18T12:25:46 < john___> because i need to read the ack flag from TM1637 chip
2014-07-18T12:25:56 < john___> what now?
2014-07-18T12:26:28 < john___> can it be also input, with pull-up resistor to 5 V?
2014-07-18T12:26:36 < jpa-> sure sure
2014-07-18T12:27:42 < john___> so I can in real-time when the code is running, say that is in input and it will be OK?
2014-07-18T12:29:27 < john___> GPIO_InitStruct.GPIO_Mode = GPIO_Mode_IN; 		
2014-07-18T12:29:32 < john___> and then
2014-07-18T12:29:45 < john___> PIO_Init(GPIOD, &GPIO_InitStruct);
2014-07-18T12:30:02 < john___> ?
2014-07-18T12:31:36 < jpa-> you can read even when it is configured as output
2014-07-18T12:31:45 < jpa-> look at the pin structure diagram in ref man
2014-07-18T12:34:36 < Claude> john___, GPIOD , you want GPIOB right?

2014-07-18T13:53:04 < john___> what am I asking, is there an equivalent statement in C for STM32F4 as Arduino: pinMode(pin, INPUT);
2014-07-18T13:53:55 < john___> in Arduino you can in run time, switch between output and input
2014-07-18T13:55:05 < effractur> y just call PIO_Init again
2014-07-18T13:55:08 < effractur> with a different config

2014-07-18T13:58:31 < john___> http://chibios.sourceforge.net/html/group___p_a_l.html
2014-07-18T13:58:56 < john___> here you have a constant: PAL_MODE_OUTPUT_OPENDRAIN
2014-07-18T13:59:10 < john___> but no open-drain for INPUT.

2014-07-18T14:01:01 < Steffanx> that's because it's some type of "output" not input ;)
2014-07-18T14:01:26 < effractur> ju open-drain is only output
2014-07-18T14:01:57 < john___> ok, open-drain only output
2014-07-18T14:02:30 < john___> if I switch to regular input, with pull up resistor to 5V will it blow up the chip?
2014-07-18T14:02:51 < effractur> if the input is 5v tollerant
2014-07-18T14:03:09 < john___> yes it is 5V tollerant
2014-07-18T14:03:43 < john___> so no blowing up?
2014-07-18T14:04:41 < john___> sorry I don't have any knowledge of electronics
2014-07-18T14:04:48 < john___> just starting here
2014-07-18T14:04:59 < john___> so, be clear with explanation
2014-07-18T14:05:09 < effractur> Steffanx:
2014-07-18T14:05:21 < john___> I don't want to destroy stm32f4
2014-07-18T14:05:49 < effractur> what are you trying to drive?
2014-07-18T14:05:59 < Steffanx> effractur: ?
2014-07-18T14:06:28 < effractur> Steffanx: if you put 5v on a 5v tolerant pin
2014-07-18T14:06:39 < effractur> it will not break, but does that coun't for all the input modes
2014-07-18T14:10:09 < jpa-> john___: an open-drain output in '1' state is equivalent to input
2014-07-18T14:10:47 < Steffanx> jpa-, just to make it even harder for him ;)
2014-07-18T14:12:57 < jpa-> harder?
2014-07-18T14:13:15 < Steffanx> i meant, more confusing.
2014-07-18T14:15:11 < john___> so reading the pin will say 1, but also you can write to the pin although it's logical 1

2014-07-18T14:39:13 < Claude> john___, usually a MCU pin has an output and an input register. the input register is independent of the output register and you can almost always read back the current pin state with the input register
2014-07-18T14:40:09 < Claude> don't know about arduidioto api but on AVRs you can do it as well
2014-07-18T14:42:47 < Claude> so even when you switch the pin into open drain output mode , you can still read back the value! when your mt124whatver chips acks a message (by pulling the data in pin to low) you will be still able to read that back into your stm32

2014-07-18T14:44:32 < john___> Claude: do you have any experience with chibiOS?
2014-07-18T14:44:40 < Claude> for example I2C works exactly that way . sda and scl are open drain on the mcu and the slave can , for example, hold scl low to extend the clock cyle and the master (mcu) checks for the level on the scl pin
2014-07-18T14:47:32 < Claude> john___, no . but wait why do you want to use chibios now? because of the gpio stuff?? if so , do you think it is a good idea to add an extra layer of abstraction just to get something simple as gpio running?
2014-07-18T14:49:05 < john___> chibiOS has delay functions or sleep functions
2014-07-18T14:49:14 < john___> that's what I need
2014-07-18T14:50:44 < __rob> you can do your own delay with a for loop
2014-07-18T14:50:58 < __rob> chibiOS delay will context switch as it provides a scheduler
2014-07-18T14:51:14 < john___> yes i know, but i need 3 sec of delay
2014-07-18T14:51:18 < john___> not 1 ms
2014-07-18T14:51:22 < __rob> if your having problems with basic gpio with the spl, I reckon you'll compound it with chibios
2014-07-18T14:51:34 < __rob> till your used to the hardware..
2014-07-18T14:51:53 < __rob> I guess if your fine with the software side of things, its a pretty nice abstraction..

2014-07-18T17:06:23 < dongs> theres like nothing on it

2014-07-18T17:10:02 < dongs> can i configure TIMx_CH complementary ouputs to be *exactly* same as regular ones?
2014-07-18T17:10:17 < dongs> or are tehy always gonna be inverted/out of phase or whatever
2014-07-18T17:10:40 < dongs> i can remap all these fucking CH_N outputs but if i cant use them they're fucking useless
2014-07-18T17:12:17 < jpa-> if you don't need the positive channel, just invert the pin in timer config?
2014-07-18T17:12:42 < dongs> not only i dont *need* positive channel, it conflicts with some other shit i wanna use (USB) so i'm not sure if itll work
2014-07-18T17:12:59 < dongs> cause i think to get complementary one i need to enable the normal one too right

2014-07-19T04:21:36 < gxti> maybe just smashed stack, none of the wait-related fields in the thread structure are set and the addresses in the stack don't make a lot of sense

2014-07-19T05:17:54 < dongs> due to thermal stress yadda yadda
2014-07-19T05:18:07 < zyp> ah, right
2014-07-19T05:19:39 < dongs> basically everything below 8.2 section is gone

2014-07-19T05:20:09 < dongs> maybe they moved that shit to appnotes

2014-07-19T05:24:06 < dongs> Do not drop individually packaged sensors, or trays of sensors onto hard surfaces. Components placed in trays could be
2014-07-19T05:24:09 < dongs> subject to g-forces in excess of 10,000g if dropped.
2014-07-19T05:25:47 < zyp> yeah
2014-07-19T05:26:00 < zyp> any mems device I've seen has that warning
2014-07-19T05:27:26 < zyp> F=m*a which gives a=F/m, and since the mass is so small, you don't need a lot of force to get a shit ton of acceleration
2014-07-19T05:27:58 < dongs> how much would say drop from 1m  to cement/steel floor do

2014-07-19T12:27:05 < zebra> hello
2014-07-19T12:27:31 < zebra> i would like to know if someone has any experience with chibiOS
2014-07-19T12:27:40 < zebra> i have downloaded the zip
2014-07-19T12:28:07 < dongs> Tectu is the resident kawaiiOS supporter
2014-07-19T12:29:24 < zebra> i don't know which directory is main?
2014-07-19T12:29:31 < zebra> for chibiOS
2014-07-19T12:29:39 < zebra> i was looking the examples
2014-07-19T12:29:49 < zebra> and all you need is two include headers
2014-07-19T12:34:08 < dongs> how would a device running at 2.5V VDD react to I/O at 3.3V
2014-07-19T12:34:17 < dongs> (ratings specify VIH as 100% VDD)
2014-07-19T12:34:21 < dongs> for "max"
2014-07-19T12:36:56 < jpa-> dongs: probably it has ESD diodes to VDD, so it would clamp the IO to about 3.0V
2014-07-19T12:37:10 < jpa-> with a series resistor it would probably work and not break
2014-07-19T12:46:05 < dongs> hm
2014-07-19T12:52:08 < qyx_> there should be no problem with 5V tolerant io
2014-07-19T12:52:27 < dongs> fucking hate shit that can run at < 3.3V but doesn't have vddio pins
2014-07-19T12:53:17 < qyx_> if pin can be at 5V with 3.3Vdd i see no problem with 3.3V io and 2.5VDD for FT pins
2014-07-19T12:53:30 < zyp> that's right
2014-07-19T12:53:45 < dongs> no, my stm32 is at 3.3V, but device is at 2.5V
2014-07-19T12:53:51 < dongs> that its talking to
2014-07-19T12:53:53 < zyp> but a FT pin outputting 3.3V into a 2.5V device won't help
2014-07-19T12:54:13 < dongs> so output from 2.5V device is ok (since min is ~1.85
2014-07-19T12:54:14 < qyx_> you can do it arduino style
2014-07-19T12:54:16 < qyx_> resistor divider!
2014-07-19T12:54:21 < dongs> laff
2014-07-19T12:55:54 < qyx_> i though you were reffering to stm32 with "device"
2014-07-19T12:56:08 < dongs> stm32 cant run at 2.5 isnt?
2014-07-19T12:56:12  * dongs checks
2014-07-19T12:56:28 < dongs> anyway, no, it'll be even more aids with running it at 2.5 than dealing with a single 2.5V device
2014-07-19T12:56:28 < qyx_> there are some which run from 1.71
2014-07-19T12:57:38 < zebra> is someone using IAR embedded workbench?
2014-07-19T12:57:48 < zyp> I hope not
2014-07-19T13:06:11 < zebra> so using IAR embedded workbench is a bad thing?
2014-07-19T13:09:14 < zyp> I'm joking
2014-07-19T13:16:10 < dongs> i'd say so
2014-07-19T13:16:24 < dongs> last i tried it, it was complete shit
2014-07-19T13:16:35 < dongs> if youre gonna use something commercial at least use keil/armcc
2014-07-19T13:18:10 < dongs> who the fuck makes ewarm compiler?

2014-07-19T15:05:44 < john_____> hello, which statement in stm32f4 for driving gpio is equivalent to this:
2014-07-19T15:05:45 < john_____> In I2C bus, the connected components must not drive the bus high directly, but rather set it to hi-z (tri-state) and let the pull-up resistor pull the bus high
2014-07-19T15:06:00 < dongs> openDrain
2014-07-19T15:06:08 < dongs> (just like any i2c
2014-07-19T15:06:57 < dongs> so GPIO_Mode_OD or whatever
2014-07-19T15:07:04 < dongs> lookup pinmode stuff.
2014-07-19T15:07:27 < dongs> (if you're planning to manually drive it that is... if youre using I2C peripheral i  think you just set it to apropriate AF and it will do correct things for you
2014-07-19T15:09:06 < john_____> when i confgiure gpio pin to open-drain, do I set it to logical 0

2014-07-19T15:09:52 < dongs> no, you just do same high/low shit as you need
2014-07-19T15:10:34 < john_____> so open drain + low to read input
2014-07-19T15:10:45 < john_____> and open drain + high to output
2014-07-19T15:10:48 < dongs> read, you just read from gpio->IDR
2014-07-19T15:10:53 < dongs> you dont need to do anything
2014-07-19T15:11:08 < dongs> because other device is driving the bus (hopefully) while you're reading.
2014-07-19T15:11:14 < dongs> and you shouldn't be.
2014-07-19T15:14:10 < john_____> do you have arduino?
2014-07-19T15:14:29 < john_____> there you set the setPinmode(pin,input)
2014-07-19T15:15:01 < john_____> so this is equialent to open-drain

2014-07-19T15:55:16 < dongs> what the fuck
2014-07-19T15:55:32 < dongs> I've managed to speed up assembly time, which has been the real bottleneck of the whole process, by getting a manual pick and place machine. What this allows me to do is, instead of painstakingly counting, picking up, and placing each component on the circuit board with tweezers, I now have a organized system of storing the parts, and a tool designed specifically for picking them up and placing them on the circuit boards.

2014-07-19T16:31:24 < jadew> $150 for a USB LA?
2014-07-19T16:31:27 < jadew> what's the catch?
2014-07-19T16:31:49 < dongs> you get it 4 yearss later
2014-07-19T16:31:55 < dongs> and without software
2014-07-19T16:31:56 < jadew> lol
2014-07-19T16:32:16 < dongs> i duno i have ellisys usb2 analyzer i paypal'd
2014-07-19T16:32:56 < dongs> it wasnt $150 tho but it works
2014-07-19T16:32:57 < Steffanx> and screwed the seller by requesting a refund?
2014-07-19T16:33:18 < jadew> so for $150 you get a FPGA dev board?
2014-07-19T16:33:25 < dongs> with usb host
2014-07-19T16:33:26 < dongs> or something
2014-07-19T16:33:52 < jadew> sweet deal
2014-07-19T16:34:01 < mumptai> which isn't that bad, for a prototype style device
2014-07-19T16:34:07 < dongs> $1000 -- You should all be taken care of, hopefully, except for one backer who I have never actually heard from ever. Let me know.
2014-07-19T16:34:10 < dongs> found zyp's pledge
2014-07-19T16:36:18 < Steffanx> At least the fgpa part is written in python, that makes dongs happy.
2014-07-19T16:36:31 < dongs> uh huh
2014-07-19T16:36:55 < mumptai> wasn't that migen/fhdl ?
2014-07-19T16:37:28 < dongs> they changed target like 3 times
2014-07-19T16:37:34 < Steffanx> Yes mumptai
2014-07-19T16:37:45 < dongs> hm, i wonder why the fuck their pcbs dont have guides for assembly
2014-07-19T16:37:48 < dongs> and why its not panelized either
2014-07-19T16:38:02 < dongs> maybe thats why they can only get time on a shitty slow dicknplace
2014-07-19T16:38:19 < Steffanx> non-pro irc EE PCB designers for pick 'n place machines.
2014-07-19T16:38:28 < dongs> yea
2014-07-19T16:38:43 < mumptai> the short sides have an unpopulated area large enough for the feeders
2014-07-19T16:39:04 < gregor_> how do you import whole directory with files in IAR embedded workbench?
2014-07-19T16:39:23 < dongs> one by one
2014-07-19T16:39:25 < Steffanx> gregor_ you really should try to visit the help of IAR.
2014-07-19T16:39:29 < Steffanx> or their website.
2014-07-19T16:39:43 < dongs> mumptai: hm yeah, guess so.

2014-07-19T16:40:11 < Steffanx> It seems that no one here uses IAR.
2014-07-19T16:40:19 < dongs> so thats manual process.

2014-07-19T16:44:39 < mumptai> that'll be after reflow, and probably a manual process
2014-07-19T16:44:41 < dongs> fuck dropbox
2014-07-19T16:45:00 < mumptai> k
2014-07-19T16:45:03 < dongs> thats on teh way to reflow
2014-07-19T16:45:20 < mumptai> someone is having fun ...
2014-07-19T16:45:54 < mumptai> not even slightly optimized for manufacturing ...
2014-07-19T16:46:31 < dongs> typical dickstarter.
2014-07-19T16:46:45 < dongs> and same machine doing passives and qfp is also fail
2014-07-19T16:47:18 < mumptai> com'on it still is a small run
2014-07-19T16:47:32 < qyx_> why is there that much company logos?
2014-07-19T16:47:40 < dongs> maybe they're all paying to be there
2014-07-19T16:47:44 < dongs> esp that pirated altium
2014-07-19T16:48:15 < Steffanx> qyx_: that was the $1000 pledge thingy
2014-07-19T16:49:19 < dongs> oh,hah.
2014-07-19T16:49:27 < dongs> the \Z logo must be zyp then
2014-07-19T16:57:21 < dongs> k i found a board whre i can test 2.5V device with 3.3V io
2014-07-19T16:57:26 < dongs> lets see if it catches smoke
2014-07-19T16:57:38 < dongs> no resistor or anything
2014-07-19T16:59:09 < Steffanx> Isn't it easier to check the datasheet if the inputs f that 2.5V can handle 3.3V?
2014-07-19T16:59:26 < Steffanx> *of that 2.5V device
2014-07-19T16:59:38 < dongs> of course i did that alradyt
2014-07-19T17:00:02 < Steffanx> and i guess it's out of spec?
2014-07-19T17:00:25 < dongs> hard to tell
2014-07-19T17:00:35 < dongs> they dont have absolute maximum ratings on I/O
2014-07-19T17:00:37 < dongs> only on vdd
2014-07-19T17:00:39 < dongs> which is 4V
2014-07-19T17:00:43 < Steffanx> Ah.
2014-07-19T17:00:48 < dongs> but Vih is "100% vdd"
2014-07-19T17:01:12 < GargantuaSauce> latchup here we come!
2014-07-19T17:01:15 < dongs> under "max"

2014-07-19T17:03:52 < dongs> no.
2014-07-19T17:04:19 < Steffanx> What fancy ic is this?
2014-07-19T17:04:39 < dongs> lol
2014-07-19T17:04:41 < dongs> it doesnt work
2014-07-19T17:04:42 < dongs> damnit.
2014-07-19T17:10:07 < dongs> haha
2014-07-19T17:10:08 < dongs> not only that
2014-07-19T17:10:37 < effractur> you broke it?
2014-07-19T17:11:09 < dongs> nope
2014-07-19T17:11:17 < dongs> but its backfeeding 3.3V I/O into 2.5 rail
2014-07-19T17:11:20 < dongs> so its more iek 2.8V
2014-07-19T17:11:27 < dongs> so yea, not gonna work.
2014-07-19T17:17:06 < Steffanx> limiting the current doesnt fork?
2014-07-19T17:17:51 < dongs> 4 layer pcb, all I/o is on 3rd layer
2014-07-19T17:18:29 < Steffanx> hmpf
2014-07-19T17:19:21 < dongs> the fact that it fucks with 2.5V rail already from the 3.3V on I/O pins ..
2014-07-19T17:19:44 < dongs> http://www.maximintegrated.com/en/products/interface/level-translators/MAX3390E.html wonder how expensive that shit is..
2014-07-19T17:19:48 < dongs> but that's another 3x3mm part on the board
2014-07-19T17:19:50 < dongs> something I dont really wanna do

2014-07-19T19:00:52 < gregor_> which IDE do you use for building and uploading to the board?
2014-07-19T19:03:50 < dongs> what "board"
2014-07-19T19:04:46 < zyp> gdb
2014-07-19T19:07:06 < gregor_> the stm32 boards
2014-07-19T19:07:18 < gregor_> i have big problem with IAR
2014-07-19T19:07:30 < gregor_> and I need something new
2014-07-19T19:07:43 < dongs> why the fuck theres all these people using IAR in here lately
2014-07-19T19:07:45 < dongs> and all failing with it
2014-07-19T19:07:51 < dongs> are you sure your problems are actualyl IDE related
2014-07-19T19:07:53 < dongs> and not just you being dumb
2014-07-19T19:08:09 < dongs> cuz liek.. it should at least be able to do basic shit
2014-07-19T19:08:16 < dongs> like compile and upload and debug code.
2014-07-19T19:08:21 < dongs> doesnt amtter which one y ou pick
2014-07-19T19:08:58 < gregor_> well IAR sometimes work and sometimes it does not
2014-07-19T19:08:59 < zyp> yeah
2014-07-19T19:09:15 < zyp> learning to use whatever tools you choose is more important than which tools you choose
2014-07-19T19:10:36 < gregor_> IAR can't even read the path which I set
2014-07-19T19:12:04 < dongs> that sounds like it fits under the "failing to use the tools" part.
2014-07-19T19:12:20 < dongs> i doubt that a $5000 piece of software would lack basic functionality
2014-07-19T19:12:36 < bvsh> gregor_, i hope you didn't pay for it
2014-07-19T19:17:17 < gregor_> i have free version of iar

2014-07-20T09:28:50 < dongs> PaulFertser: thanks!
2014-07-20T09:29:30 < PaulFertser> dongs: I haven't tested it anyhow but it builds fine with gcc-arm-embedded. LTO seems to be a major win when using the ST shit-library.
2014-07-20T09:29:31 < dongs> i presume this works with gcc-arm-embedded?
2014-07-20T09:29:42 < dongs> aye, i guess i just got my answer :)
2014-07-20T09:29:52 < dongs> if you got a .hex i can flash to test out, i can :)
2014-07-20T09:30:00 < PaulFertser> I've also tested the latest version with current TNT and it required removing --specs=nano.specs as TNT builds only a single newlib library.
2014-07-20T09:30:30 < dongs> hm, is there any way to stub that _init() somewehre else?
2014-07-20T09:30:34 < dongs> like in startup asm?
2014-07-20T09:30:40 < dongs> for _gcc
2014-07-20T09:30:54 < dongs> cause,, it might conflict w/some internal trash in keil (unlikely, but
2014-07-20T09:31:26 < PaulFertser> dongs: http://paulfertser.info/baseflight_NAZE.hex is the hex generated with 4.9.0 with newlib-nano and lto all the way.
2014-07-20T09:31:47 < PaulFertser> Yes, _init can be added anywhere, including startup asm.
2014-07-20T09:31:58 < dongs> wow not much bigger
2014-07-20T09:32:01 < PaulFertser> Why use different startups for Keil and gcc?
2014-07-20T09:32:02 < dongs> than -keil
2014-07-20T09:32:03 < dongs> impress
2014-07-20T09:32:07 < dongs> PaulFertser: different asm syntax lols
2014-07-20T09:32:13 < dongs> and slightlyt different session naming
2014-07-20T09:32:18 < dongs> er section
2014-07-20T09:32:54 < PaulFertser> ARM boasted their Cortex-M3 doesn't require asm startups anymore and it can all be done in C, and that's actually true.
2014-07-20T09:33:15 < PaulFertser> I can stuff it inside .s, yes.
2014-07-20T09:33:21 < dongs> 61200b bs 72124b
2014-07-20T09:33:40 < PaulFertser> I also have a different patch that makes some functions "static" and that should improve non-lto case.
2014-07-20T09:33:50 < dongs> hmm, and doesnt work
2014-07-20T09:34:26 < dongs> ya doesn't boot
2014-07-20T09:34:27 < dongs> hm
2014-07-20T09:34:52 < PaulFertser> Probably newlib-nano differences, https://github.com/gsmcmullin/blackmagic/commit/9c95f039cfb45619d1b9c5bc17d47984bea81029
2014-07-20T09:35:15 < PaulFertser> I.e. nano requires %x for scanf to work nicely, but not %X.
2014-07-20T09:37:04 < timemob> it doesn't boot tho. locked up or something can't rely tell.
2014-07-20T09:37:08 < timemob> no light
2014-07-20T09:37:46 < PaulFertser> I'd step-by-step it on hardware, must be something trivial.
2014-07-20T09:39:00 < timemob> can you put up related elf
2014-07-20T09:39:04 < PaulFertser> timemob: am I right in using the default target, i.e. running "make" without parameters?

2014-07-20T09:59:59 < PaulFertser> I know
2014-07-20T10:00:03 < dongs> i think thats -current right?
2014-07-20T10:00:07 < PaulFertser> Right.
2014-07-20T10:00:28 < dongs> can y ou try with 4.7.3 make CJMCU or wahtever
2014-07-20T10:00:31 < dongs> target=CJMCU
2014-07-20T10:00:40 < dongs> hwo much lower than 64k it is for .hex
2014-07-20T10:02:37 < dongs> anyway, if it doesnt break -current I can merge this but can you stub _init() inside _gcc.S
2014-07-20T10:02:40 < dongs> instead of in main()
2014-07-20T10:02:54 < dongs> since its really gcc/newlib specific stuff
2014-07-20T10:03:19 < dongs> or at least #ifdef it under _GNUC or wahtever (tho I think keil might be setting those flags -  cuz i'm using --gnu --c99 options
2014-07-20T10:03:34 < timemob> so best place is in GCC startup
2014-07-20T10:03:35 < PaulFertser>   53888	    480	   4888	  59256	   e778	obj/baseflight_CJMCU.elf
2014-07-20T10:03:40 < PaulFertser> Need binary for that?
2014-07-20T10:03:57 < dongs> no. not bad, so leaves ~3k for code and 2k for config
2014-07-20T10:04:04 < dongs> this was for F103C8T6 proc
2014-07-20T10:04:06 < dongs> with 64k flash
2014-07-20T10:04:15 < dongs> and before i started cleaning that platform up, gcc would make it > 64k
2014-07-20T10:06:48 < PaulFertser> Why not simply remove __libc_init_array from gcc startup.s?
2014-07-20T10:07:08 < dongs> i dunno? sure? why the fuck is it there
2014-07-20T10:07:15 < dongs> i dont use gcc, so if you think it doesnt belong there, get rid of it :)

2014-07-20T16:41:26 < dongs> wiht 1280x768 screen
2014-07-20T16:41:30 < dongs> that does look fucking hideous
2014-07-20T16:41:46 < quck> I wasn't asking for chibiOS, I have been asking for external .c and .h files
2014-07-20T16:44:26 < quck> more exactly: Standard Peripherals Library Drivers (StdPeriph_Driver)
2014-07-20T16:44:48 < dongs> looking at some video of mh17, lots of people mauled while still attached to chairs
2014-07-20T16:44:53 < dongs> i guess seatbelts worked good
2014-07-20T16:45:26 < madist> you should read a description of the missile that was (allegedly) used
2014-07-20T16:45:37 < dongs> ya? the SA-11 or wahtever?
2014-07-20T16:45:49 < madist> its "warhead" is a bundle of tungsten rods that are launched spinning at the target.
2014-07-20T16:45:58 < madist> whatever is in the path turns to sphagetti

2014-07-20T17:44:30 < jpa-> why do you need a specialist? looks like a normal C error from including the same file twice
2014-07-20T17:44:45 < dongs> learn to C
2014-07-20T17:44:46 < dongs> problem solved
2014-07-20T17:44:50 < jpa-> are you trying to mix chibios with stdperiph?
2014-07-20T17:45:09 < jpa-> i would suggest: don't
2014-07-20T17:46:02 < quck> how did i include the same file twice
2014-07-20T17:46:05 < jpa-> (could be something totally else also, can't bother seeing where your files come from because you haven't used sane paths)

2014-07-20T18:16:20 < madist> quck: you don't copy .c or .h files. you #include .h files.
2014-07-20T18:16:38 < madist> for library functions.
2014-07-20T18:30:01 < quck> yes i know that, but I have external files which I added into the project
2014-07-20T18:30:11 < quck> I think jpa- is right
2014-07-20T18:30:17 < quck> they collide with names
2014-07-20T18:37:03 < quck> so idiotic would be to change all the names for struct
2014-07-20T18:37:19 < quck> how does this collision handle in C?
2014-07-20T18:38:53 < Steffanx> what are you even trying to do? Combine chibios and the st peripheral lib? or just trying to compile something using the stdperipheral lib only?
2014-07-20T18:39:40 < quck> no chibiOS
2014-07-20T18:39:45 < quck> the second one
2014-07-20T18:40:21 < quck> in eclipse it import gpio hal
2014-07-20T18:40:25 < quck> imports*
2014-07-20T18:40:26 < Steffanx> Then you problably included the peripheral lib twice or something like that.
2014-07-20T18:40:40 < quck> yes it is twice
2014-07-20T18:40:44 < madist> he copied the .c file into his project. read the log.
2014-07-20T18:40:53 < quck> yes
2014-07-20T18:40:58 < quck> but here is the catch
2014-07-20T18:41:12 < quck> the eclipse uses some hal gpio.c
2014-07-20T18:41:19 < quck> already imported
2014-07-20T18:41:37 < quck> when I import extern std peripherial library
2014-07-20T18:41:40 < quck> they collide
2014-07-20T18:41:42 < quck> with names
2014-07-20T18:42:10 < quck> if I remove the allready imported some error occurs
2014-07-20T18:42:23 < quck> what is this hal thing?

2014-07-21T04:21:00 < aadamson> dongs yea, removing a DC bias that is too high (say 0-2V with idle at 1V) and I need to put it on a VCXO input that needs to center at .9v.  I'd rather not do it with just a VD, so take the original ac couple to remove the pwm dc bias, and add back a .9v centered dc bias :)

2014-07-21T10:02:45 < upgrdman> auto is a keyword... automatic variable

2014-07-21T10:02:57 < upgrdman> hmmm
2014-07-21T10:03:04 < zyp> auto is C++11

2014-07-21T10:03:15 < jpa-> c++11 gives new meaning to auto

2014-07-21T10:04:11 < Thorn> auto has been in C since it was born iirc
2014-07-21T10:04:14 < Thorn> they just reused it in c++11
2014-07-21T10:04:38 < dongs> can't say i've *ever* used that.
2014-07-21T10:04:43 < dongs> or was even aware of its existence.
2014-07-21T10:04:50 < zyp> same
2014-07-21T10:04:57 < jpa-> of course, no-one has because it is useless.. just like func(void) ;)
2014-07-21T10:05:04 < dongs> eewrong
2014-07-21T10:05:06 < jpa-> (though func(void) has its purpose :)
2014-07-21T10:05:07 < zyp> the register keyword is also pretty dumb
2014-07-21T10:05:09 < dongs> func(void) is very clear
2014-07-21T10:05:35 < upgrdman> so is ()
2014-07-21T10:05:44 < dongs> no
2014-07-21T10:05:49 < dongs> () = java
2014-07-21T10:06:01 < zyp> I don't see why «void» is any more intuitive than an empty list of arguments
2014-07-21T10:06:07 < upgrdman> ^
2014-07-21T10:06:16 < jpa-> http://paste.dy.fi/4Lf/plain   gives error only for func2(), not for func1()
2014-07-21T10:06:19 < zyp> IMO it's counterintuitive
2014-07-21T10:06:30 < Thorn> void foo(); in C means "takes any arguments"
2014-07-21T10:06:45 < Thorn> void foo(void); -- no arguments
2014-07-21T10:06:50 < zyp> jpa-, I'm aware of the difference, but that doesn't mean I can't argue it's dumb
2014-07-21T10:06:56 < jpa-> zyp: i agree
2014-07-21T10:07:05 < jpa-> just like {}; being not allowed is dumb :)

2014-07-21T10:07:50 < upgrdman> im guessing variadic shit, but without something to indicate the number or type of args, that might be difficult
2014-07-21T10:07:57 < zyp> upgrdman, you can declare func() in a header and have the actual function read args
2014-07-21T10:08:00 < zyp> or something
2014-07-21T10:08:05 < upgrdman> o
2014-07-21T10:08:07 < zyp> it's dumb either way

2014-07-21T10:08:15 < dongs> if i saw code doing shit liek that
2014-07-21T10:08:18 < dongs> i'd have to murder the writer
2014-07-21T10:08:25 < upgrdman> and in that case, only the linker will save your ass if you fuck up the arg type/count?
2014-07-21T10:08:52 < jpa-> no, linker does not save you
2014-07-21T10:08:56 < zyp> dongs, agreed, and that's why func() vs func(void) is dumb and why C++ has changed it to be sane

2014-07-21T10:12:46 < upgrdman> off topic, but i recall reading somwhere about self-modifying code as a means of virus speading or copy protection. would self-modifying code be possible with a harvard arch?
2014-07-21T10:13:07 < zyp> depends
2014-07-21T10:13:19 < dongs> you'd have to erase a flash page ... :)
2014-07-21T10:13:25 < dongs> or run from ram..
2014-07-21T10:13:38 < zyp> that also depends
2014-07-21T10:13:47 < zyp> what do you count as a harvard arch?
2014-07-21T10:14:12 < upgrdman> "a computer architecture with physically separate storage and signal pathways for instructions and data"
2014-07-21T10:14:29 < zyp> cm3 is technically a harvard arch since the cpu has separate D and I buses, but they get hooked to the same memory space
2014-07-21T10:14:34 < jpa-> e.g. pics can write to their own flash while running; but of course you'll wear the memory out

2014-07-21T10:15:15 < jpa-> but self-modifying code is just one technique in obfuscation
2014-07-21T10:15:32 < zyp> same goes for AVR
2014-07-21T10:15:47 < zyp> AVR is harvard with I hooked to flash and D hooked to sram
2014-07-21T10:16:15 < zyp> but flash can still be read and written through special instructions, so self modifying code is still possible
2014-07-21T10:16:23 < upgrdman> oh that reminds me, is it possible to flash an stm32 and have it not erase/overwrite a certain flash page? like if you were using the last page to store calibration constants or whatever? openocd if that makes a diff.
2014-07-21T10:16:33 < zyp> sure
2014-07-21T10:16:40 < zyp> as long as you don't do a full chip erase
2014-07-21T10:16:46 < PaulFertser> jpa-: yes, I've tried your suggestion today and saw it produces a warning with pedantic.
2014-07-21T10:17:00 < upgrdman> k. will have to reading the openocd docs.
2014-07-21T10:17:03 < zyp> just do page/sector erase and the untouched pages/sectors will retain their contents
2014-07-21T10:17:08 < jpa-> PaulFertser: yeah, so it does; if you care about -pedantic, {0} is the nicest work-around
2014-07-21T10:17:45 < PaulFertser> upgrdman: openocd doesn't erase all the target by default.
2014-07-21T10:18:04 < PaulFertser> upgrdman: so if you just load a new binary that doesn't have anything on that page, it shouldn't be erased afaict.

2014-07-21T11:25:40 < dongs> hm, .lst files? yeaH I generate those
2014-07-21T11:25:44 < dongs> lemme see if they're usable
2014-07-21T11:26:32 < dongs> found
2014-07-21T11:26:36 < dongs> yeah, i can make.
2014-07-21T11:26:50 < dongs> its not amazing gcc asm tho.

2014-07-21T11:30:16 < PaulFertser> gcc doesn't understand asm at all, assemblers are part of binutils. Also, AT&T vs Intel syntax debate is so last century. And btw, isn't standard ARM assembly syntax more like AT&T's?

2014-07-21T11:35:36 < PaulFertser> How come there're separate listing files per module?
2014-07-21T11:35:40 < dongs> its called 'cross module optimization'
2014-07-21T11:35:43 < dongs> it does like 3-4 passes
2014-07-21T11:35:49 < dongs> re-building some of the files.
2014-07-21T11:35:55 < PaulFertser> Funky
2014-07-21T11:36:16 < PaulFertser> Thank you for the input, I hope I'll have fun time comparing them.
2014-07-21T11:36:35 < PaulFertser> Of course it would be better to file bugs for missing optimisations...
2014-07-21T11:36:59 < dongs> there's a good one that i'm aware of

2014-07-21T11:50:03 < john___> can I use free rtos with gpio commands?
2014-07-21T11:50:12 < dongs> wat
2014-07-21T11:50:20 < dongs> whjat does OS have to do with GPIO
2014-07-21T11:50:34 < dongs> you can directly write to GPIOx->BRR/BSRR if you want.
2014-07-21T11:50:46 < madist> I thought you said you had figured out how to identify IAR guy.
2014-07-21T11:50:54 < dongs> thats not IAR guy tho
2014-07-21T11:51:03 < dongs> .. unless ive got trolled again
2014-07-21T11:51:27 < madist> that's IAR guy. 90% confidence.
2014-07-21T11:51:56 < john___> nothing, but someone has said that it's a not good idea mixing OS with other commands
2014-07-21T11:52:28 < john___> who is IAR guy?
2014-07-21T11:54:06 < jpa-> you are probably confusing HAL and OS
2014-07-21T11:54:38 < jpa-> and even HAL can be combined with direct register access, as long as you know what you are doing
2014-07-21T11:59:58 < dongs> good hal makes stuff like setgpio(foo) { _gpiopinstate = foo; hardware->foo; } and then getgpio(foo) is { return _gpiopinstate; }

2014-07-21T13:28:50 < __rob> can anyone recommend a tcpip stack ?
2014-07-21T13:29:02 < __rob> there seem to be a few. Only requirement is that its free,
2014-07-21T13:29:26 < zyp> not that it works?
2014-07-21T13:29:37 < __rob> well thats implicit :)
2014-07-21T13:29:47 < __rob> its not a tcpip stack if it doesn't work, no ?
2014-07-21T13:29:51 < __rob> its just random code
2014-07-21T13:30:19 < zyp> what if it sometimes work?
2014-07-21T13:30:24 < jpa-> ever seen a significant piece of code that works in 100% of cases?
2014-07-21T13:30:49 < __rob> ok, add that to the list of requirements, tried and tested
2014-07-21T13:30:54 < __rob> and people use it
2014-07-21T13:31:06 < __rob> be nice if there is already a freertos port
2014-07-21T13:31:09 < Steffanx> lwip has been around for a pretty long time ..
2014-07-21T13:31:56 < Steffanx> and im pretty sure there is a freerots port of it.
2014-07-21T13:32:03 < __rob> great, i'll take a look
2014-07-21T13:34:20 < john___> why ST peripherial crap?
2014-07-21T13:34:28 < john___> is*
2014-07-21T13:34:58 < jpa-> ask ST
2014-07-21T13:35:12 < __rob> looks like that lwip is used by stm for the Cube stuff
2014-07-21T13:35:31 < __rob> so must be a port
2014-07-21T13:37:02 < john___> can I mix stuff from free rtos with chibiOS with all the other stuff=
2014-07-21T13:37:04 < john___> ?
2014-07-21T13:37:24 < __rob> i've taken chibios stuff for freertos
2014-07-21T13:37:36 < __rob> you have to change any os specific stuff though
2014-07-21T13:37:56 < __rob> but the layout, ie what each task does, and anything using the stm32 peripheral library is the same
2014-07-21T13:38:14 < DanteA> Depends at the kind of stuff...
2014-07-21T13:38:27 < jpa-> john___: only if you know what you are doing
2014-07-21T13:40:31 < DanteA> Good answer.
2014-07-21T13:40:31 < DanteA> :)
2014-07-21T13:40:48 < __rob> so has anyone tried the stm32cube stuff ?
2014-07-21T13:41:11 < __rob> just downlaoded it for the f4, and it looks like ver2 of peripheral library
2014-07-21T13:42:31 < __rob> or rather more wrappers around the original one..
2014-07-21T13:42:44 < jpa-> just what stdperiph was missing, moar wrappers!
2014-07-21T13:42:55 < __rob> well yea.. I dont quite get the need for it
2014-07-21T13:43:11 < __rob> the stm32pl wraps eveyrthing a ton anyway
2014-07-21T13:43:35 < __rob> the pin planner is nice though

2014-07-21T13:49:28 < dongs> now its called STMTimeCubeMX or something
2014-07-21T13:49:35 < dongs> i actually installed taht shit few days ago
2014-07-21T13:49:45 < dongs> it was good enough to export pin names->PortX mapping

2014-07-21T13:49:49 < dongs> without making any code
2014-07-21T13:49:59 < dongs> so I could make a part in altium by importing the stuff
2014-07-21T13:50:20 < __rob> the setup code generation is such a small part of the manual work anyway.. that it almost seems pointles

2014-07-21T16:37:41 < john___> how big is a register for reading data on gpio on stm32f4?
2014-07-21T16:38:22 < dongs> wider than your typical soundstage

2014-07-21T16:39:03 < john___> so one byte?
2014-07-21T16:40:04 < DanteA> 32 is nothing talks to you?...
2014-07-21T16:40:27 < DanteA> In the name of your mcu
2014-07-21T16:41:21 < madist> ST doesn't have any tutorials of the type "click on this, now click on that" and "copy the follwing code and paste it into main.c" ?
2014-07-21T16:41:34 < dongs> no, thats only for arduino due
2014-07-21T16:41:50 < dongs> i'm starting to see tardruino due in some shit on hackaday
2014-07-21T16:41:53 < dongs> irts pretty funny
2014-07-21T16:41:54 < madist> MSP430 has tutorials like that.
2014-07-21T16:43:01 < scrts_w> retarduino?
2014-07-21T16:43:15 < madist> You people are such a bunch of elitists.
2014-07-21T16:43:33 < madist> Arduino will conquer the world, just like MS Windows did.
2014-07-21T16:44:37 < scrts_w> I agree regarding the hardware platform
2014-07-21T16:44:45 < scrts_w> but not the sketch stuff and its own language
2014-07-21T16:45:26 < john___> yes i know that inside registers are 4 bytes, but this register is for reading data and other one for writing
2014-07-21T16:45:37 < dongs> john___: have you tried looking at the HEADER FILE
2014-07-21T16:45:44 < dongs> which contains this register/struct definition
2014-07-21T16:45:53 < dongs> it might: contain the answer
2014-07-21T16:46:30 < john___> the datasheet also contains the answer
2014-07-21T16:46:44 < DanteA> Really? :)
2014-07-21T16:47:37 < john___> but instead of reading those 1000 pages I ask you people
2014-07-21T16:47:39 < PaulFertser> There's something funky with sbrk from newlib-nano, can't understand yet what it really is but looks like it's comparing the address it was going to return with stack pointer and if it's bigger, it returns -1...
2014-07-21T16:47:43 < PaulFertser> What a surprise
2014-07-21T16:51:54 < gxti> PaulFertser: what's wrong with that?
2014-07-21T16:52:42 < PaulFertser> And some older startup used by this project I was debugging is using an area in BSS for the stack...
2014-07-21T16:54:59 < Thorn> it evidently assumes that stack is always above heap

2014-07-21T16:55:12 < PaulFertser> Damn, so stupid... And I've spent considerable time understanding why it doesn't work with the current newlib-nano, meh. Had to look through the assembly of _sbrk to finally understand what's happening.
2014-07-21T16:56:51 < gxti> in the traditional virtual memory model, the heap starts at the bottom of the address space and the stack starts at the top, and they grow towards each other. obviously makes no sense without virtual memory but it's not like there's anything else it could assume by default.

2014-07-21T16:57:46 < gxti> i didn't realize newlib even had a default sbrk, i ended up implementing my own that uses a bounded region.
2014-07-21T17:01:15 < PaulFertser> -lnosys provides you with all the basic syscalls you need to have a linkable newlib-based project.

2014-07-22T08:41:47 < dongs> (i asked for 0402 r,g,b
2014-07-22T08:41:51 < dongs> apparently does existr
2014-07-22T08:41:57 < dongs> 1x1mm RGB
2014-07-22T08:44:40 < emeb_mac> tiny!
2014-07-22T08:44:46 < dongs> yea
2014-07-22T08:44:51 < dongs> i wish i had some application for it
2014-07-22T08:45:06 < dongs> other than buying 2080000 of them
2014-07-22T08:45:32 < emeb_mac> that's a lot
2014-07-22T08:45:45 < emeb_mac> make a 1000x1000 array
2014-07-22T08:45:51 < dongs> 1920 x 1080 array
2014-07-22T08:46:02 < emeb_mac> even better
2014-07-22T08:46:13 < emeb_mac> driving that array could be... fun
2014-07-22T08:46:36 < jpa-> also, 2000 amperes of current.. minimum
2014-07-22T08:47:34 < emeb_mac> seems overinflated

2014-07-22T08:48:04 < emeb_mac> 300ma/diode?
2014-07-22T08:48:25 < jpa-> i calculated at 1mA per diode (so 0.3mA per color)
2014-07-22T08:48:45 < emeb_mac> ah - all on at once
2014-07-22T08:48:50 < emeb_mac> unlikely
2014-07-22T08:48:54 < jpa-> well average, anyway

2014-07-22T08:51:43 < emeb_mac> also the supply current seems to average out, so lots of white on the display makes it dimmer
2014-07-22T08:51:59 < dongs> how you driving htem
2014-07-22T08:52:00 < dongs> spi?
2014-07-22T08:52:03 < emeb_mac> yeah
2014-07-22T08:52:08 < emeb_mac> from my F373
2014-07-22T08:52:10 < dongs> figured you'd be hardcore and i2C
2014-07-22T08:52:15 < emeb_mac> bleh
2014-07-22T08:52:16 < dongs> because i2c is the PRO BUS
2014-07-22T08:52:19 < emeb_mac> hate that
2014-07-22T08:52:37 < emeb_mac> trying to drive an Si570 PLL with I2C and having lots of "fun"
2014-07-22T08:53:04 < emeb_mac> need to clean up the connections
2014-07-22T08:53:04 < dongs> ytou should clockout scl on power up
2014-07-22T08:53:07 < dongs> to unstick any shit
2014-07-22T08:53:22 < dongs> or else it breaks hardware i2c in al lsorts of retarded ways
2014-07-22T08:53:46 < dongs> https://github.com/multiwii/baseflight/blob/master/src/drv_i2c.c#L326 > this
2014-07-22T08:53:54 < emeb_mac> it's weird - some commands work (read regs, full reset) other don't (init regs, freeze dco)
2014-07-22T08:55:44 < dongs> sounds liek typical i2c device
2014-07-22T08:55:52 < dongs> when I was writing driver for that fucking TI backlight driver with I2C
2014-07-22T08:55:54 < dongs> it was same shit
2014-07-22T08:55:58 < dongs> it would accept one command then shit itself
2014-07-22T08:56:05 < dongs> debugging it was dumb so Ijust stopped using tha shit
2014-07-22T08:56:08 < emeb_mac> yep
2014-07-22T08:56:35 < emeb_mac> I've got this prototype haywired like a christmas tree. ugly as sin
2014-07-22T08:56:41 < emeb_mac> need to clean it up srsly
2014-07-22T08:57:12 < jpa-> why would anyone haywire an ugly chistmas tree?
2014-07-22T08:57:18 < emeb_mac> haha
2014-07-22T08:58:03  * emeb_mac 's 'murican colloquialisms perplex the ferriners
2014-07-22T09:00:13 < emeb_mac> the spi oleds work fine though
2014-07-22T09:00:25 < emeb_mac> aside from the flicker
2014-07-22T09:00:32 < dongs> flicker isnt your problem tho
2014-07-22T09:00:38 < dongs> they have their own sram that they refresh from?
2014-07-22T09:00:42 < emeb_mac> yes
2014-07-22T09:01:41 < emeb_mac> pixel buffer is interleaved strangely though, so it's tough to do multi-byte writes when updating small regions.
2014-07-22T09:02:24 < dongs> is your driver gonna be GPL or grubby closed sores
2014-07-22T09:02:58 < emeb_mac> I can post it. Pretty basic stuff.
2014-07-22T09:03:07 < emeb_mac> all stdperiph
2014-07-22T09:04:25 < PaulFertser> dongs: hm, I2C clock line configured as OD?
2014-07-22T09:04:46 < dongs> PaulFertser: gpio? yes
2014-07-22T09:04:53 < emeb_mac> that's pretty normal isn't it?
2014-07-22T09:05:07 < dongs> right
2014-07-22T09:05:08 < jpa-> it allows clock stretching
2014-07-22T09:05:29 < PaulFertser> I thought for an I2C master the clock line is push-pulled, and only data is od. Well, shows my I2C lameness all right :)
2014-07-22T09:05:39 < dongs> no they're both od
2014-07-22T09:05:52 < jpa-> it's fine to make it push-pull if no slave uses clock stretching
2014-07-22T09:05:55 < emeb_mac> ya - in every I2C I've ever used.
2014-07-22T09:06:16 < dongs> goatse stretching
2014-07-22T09:06:18 < emeb_mac> (both OD)
2014-07-22T09:07:10 < PaulFertser> And btw, both bmp085/whatever and that ST i2c magnetometer seemed to have no issues with the bus, they just worked, there was no need to unstick or something.
2014-07-22T09:08:26 < dongs> oh sure its just
2014-07-22T09:08:28 < dongs> if youre debugging
2014-07-22T09:08:33 < dongs> and you braek in t he middle of i2c transaction
2014-07-22T09:08:39 < dongs> you will likely have it all nicely fucked on next debug reset

2014-07-22T13:52:08 < dongs> was retweeted in here too
2014-07-22T13:52:28 < tunebird> mm, has anyone else noticed that later (v3.3.0 for example) versions of the ST-Link utility are reeeaaaallly slow at writing the EEPROM? Is there anything I can do to change that?
2014-07-22T13:52:52 < dongs> eeprom?
2014-07-22T13:53:14 < tunebird> yeah like the STM32L series with internal EEPROM
2014-07-22T13:53:18 < dongs> right
2014-07-22T13:53:26 < dongs> why not just write to it on startup of your firmware
2014-07-22T13:53:29 < dongs> w/default gvalues
2014-07-22T13:53:52 < tunebird> I use the ST Link utility to flash some config bytes into each device (with a script that calls the CLI version)
2014-07-22T13:54:59 < tunebird> there's only like 3-4 values I need that are non-default (the program does write the default values into EEPROM at first run)
2014-07-22T13:55:21 < tunebird> but now it takes 10+ seconds per write when it used to take about 5 for the whole thing

2014-07-22T14:14:45 < Tectu_> karlp, indeed
2014-07-22T14:15:05 < karlp> scrts_w: don't suppose you've managed to get gpio irq on the carambola2 by any chance?
2014-07-22T14:15:41 < Tectu_> scrts_w, how comes that you ask? I'm trying to get some SPI crap working.

2014-07-22T14:17:58 < scrts_w> yeah, I was also interested in that, but forget it... it's useless
2014-07-22T14:18:14 < scrts_w> SPI CS0 is reserved for flash and CS1+CS2 are used for console UART
2014-07-22T14:18:30 < karlp> yeah, but ath79 has gpio CS support
2014-07-22T14:18:34 < karlp> so that's not the problem
2014-07-22T14:18:39 < scrts_w> you won't find a full datasheet of AR9331 anywhere, so there's no I2S driver and I can't develop it
2014-07-22T14:18:40 < karlp> and that's only a problem if you want to use that uart,
2014-07-22T14:18:44 < Tectu_> karlp, do you have SPI working?
2014-07-22T14:18:57 < karlp> but there's no way to get gpio irqs, so you can't have a spi device with an irq
2014-07-22T14:19:02 < Tectu_> scrts_w, karlp, http://8devices.com/community/viewtopic.php?f=13&t=782#p3299
2014-07-22T14:19:09 < scrts_w> Tectu_: basically you'd edit the driver initialization struct in the driver
2014-07-22T14:19:21 < Tectu_> scrts_w, I've seen that and I want to avoid that for some sane reasons
2014-07-22T14:19:28 < scrts_w> and select a different pin for CS
2014-07-22T14:19:29 < Tectu_> scrts_w, I'd rather bit-bang it
2014-07-22T14:19:40 < karlp> Tectu_: oh, I wasn't interested in userspace spi
2014-07-22T14:19:41 < Tectu_> I want to drive some MAX7221 (SPI to 7-segment driver) so speed is not an issue anyway
2014-07-22T14:19:56 < Tectu_> karlp, got that too late, sorry for the spam then :-P
2014-07-22T14:20:01 < tunebird> dongs: nope, haven't tried STVP, I'll try it out now
2014-07-22T14:20:02 < scrts_w> hmm, then do all the SPI by bitbang?
2014-07-22T14:20:14 < scrts_w> or maybe you can have I2C to 7seg driver?
2014-07-22T14:20:14 < Tectu_> scrts_w, most likely. Have you already done that?
2014-07-22T14:20:26 < scrts_w> I've tried i2c only
2014-07-22T14:20:38 < scrts_w> it's easy to access it from userspace
2014-07-22T14:20:42 < dongs> < Tectu_> I want to drive some MAX7221 (SPI to 7-segment driver) so speed is not an issue anyway
2014-07-22T14:20:46 < dongs> why
2014-07-22T14:20:55 < dongs> so expensive
2014-07-22T14:20:56 < Tectu_> dongs, because it updates only once a minute ;-)
2014-07-22T14:21:07 < Tectu_> I'm not really sure how one should take any use of this carambola without any proper user space peripheraly
2014-07-22T14:21:09 < dongs> yes but its insanely expensive

2014-07-22T14:21:48 < dongs> Tectu_: TLC59282 is way cheaper.
2014-07-22T14:21:56 < Tectu_> dongs, basically I need to drive four large scale 7-segment digits out of the carambola
2014-07-22T14:22:40 < dongs> are they series leds or parallel?
2014-07-22T14:22:48 < Tectu_> dongs, when doing 7-segment MAX7221 is a bit easier
2014-07-22T14:22:52 < Tectu_> dongs, series
2014-07-22T14:23:19 < scrts_w> MAX6955?
2014-07-22T14:23:56 < dongs> Tectu_: easier? 4 pnps and 8 extra resistors (for 4 digits)
2014-07-22T14:24:03 < dongs> no difference otherwise
2014-07-22T14:24:13 < Tectu_> dongs, I'll take a closer look this evening. Bookmarked it anyway. Thanks

2014-07-22T14:28:14 < Tectu_> karlp, yes, but they tend to ignore their users until you start to give the impression to start a shitstorm
2014-07-22T14:28:27 < karlp> PaulFertser: sure, but that's no good for a spi device that expects to use an interrupt
2014-07-22T14:28:43 < PaulFertser> karlp: eh, yes, indeed.
2014-07-22T14:28:44 < scrts_w> Tectu_: did you consider using Ralink?
2014-07-22T14:28:49 < karlp> PaulFertser: I want to use the kernel driver for the mrf24j40 radio, not tectu's slow spi leds :)
2014-07-22T14:29:04 < scrts_w> e.g. carambola1 or bunch of china manufactured boards with RT5350
2014-07-22T14:29:17 < PaulFertser> karlp: I think there exists a datasheet for ar9331 in public access...
2014-07-22T14:29:29 < scrts_w> PaulFertser: no
2014-07-22T14:29:31 < scrts_w> just NO

2014-07-22T14:29:59 < PaulFertser> scrts_w: well, not all atheros datasheets are easy to get. That one is easy iirc.
2014-07-22T14:30:19 < scrts_w> PaulFertser: not at all, there's no public AR9331 datasheet

2014-07-22T14:31:20 < dongs> Tectu_: thats not so bad, still probly < 20mA / string?
2014-07-22T14:31:29 < dongs> oh, 35mA max
2014-07-22T14:31:36 < dongs> and 14V

2014-07-22T14:31:46 < jpa-> Tectu_: what is samenkopen btw?
2014-07-22T14:31:55 < karlp> scrts_w: I've got a 320 page datasheet here if you want,
2014-07-22T14:32:09 < karlp> it's still not complete, but it's far more than "nothign" that you're implying
2014-07-22T14:32:14 < scrts_w> karlp: does it say PRELIMINARY on the top right?
2014-07-22T14:32:21 < dongs> Capability (Constant-Current Sink):
2014-07-22T14:32:21 < dongs> 35 mA (VCC . 3.6 V), 45 mA (VCC > 3.6 V)
2014-07-22T14:32:34 < dongs> don't they all?
2014-07-22T14:32:45 < dongs> datasheets is like last thing they write
2014-07-22T14:32:51 < karlp> scrts_w: yes, so?
2014-07-22T14:32:58 < scrts_w> so it's almost empty.. forget it
2014-07-22T14:33:09 < scrts_w> they supply FINAL datasheet with the SDK
2014-07-22T14:33:24 < Tectu_> jpa-, some dutch steffanx china importer site
2014-07-22T14:33:25 < scrts_w> so you need to sign NDA in order to get it
2014-07-22T14:33:33 < karlp> well, you need to word things differently, it has a _lot_ of stuff in it still, so don't just say, there's nothing otu there
2014-07-22T14:33:44 < scrts_w> the final datasheet has _almost_ all the stuff... almost
2014-07-22T14:33:53 < scrts_w> e.g. there's a separate datasheet how to setup audio
2014-07-22T14:34:01 < karlp> it's very light on details, sure, and you're missing the audio that you want,
2014-07-22T14:34:08 < scrts_w> the preliminary datasheet even doesn't have DPLL mentioned
2014-07-22T14:34:21 < scrts_w> it's like even doesn't exist
2014-07-22T14:34:29 < Tectu_> dongs, depends on what the dutch guy means with  "LED current Max: 35mA"   :P
2014-07-22T14:34:41 < dongs> Tectu_: exactly what it means
2014-07-22T14:35:18 < effractur> samenkopen :D
2014-07-22T14:35:34 < Steffanx> Tectu_, the dutch guy probably just copy-pasted the info given by the china fab :P
2014-07-22T14:36:54 < Tectu_> did Smd_ yet share the story about his chines board XTAL?
2014-07-22T14:37:43 < Tectu_> chinese dev board with STM32, working demo. Doing custom code -> fails. Reason: ST demo automatically switches to HSI when HSE fails. Reason why HSE fails: XTAL caps are 1uF
2014-07-22T14:38:20 < dongs> cool
2014-07-22T14:39:10 < Tectu_> scrts_w, karlp, ever done a kernel downgrade on OpenWRT?
2014-07-22T14:40:08 < karlp> wat?
2014-07-22T14:40:27 < karlp> also, take this to #openwrt-devel if you want to keep on this, there's more people there who could help anyway
2014-07-22T14:40:36 < effractur> What a kernel downrade
2014-07-22T14:40:40 < effractur> grade*
2014-07-22T14:40:53 < effractur> What is the purpuse of that
2014-07-22T14:41:15 < Tectu_> I have to downgrade from 3.10.44 to some 3.7 kernel in order to use the shitty "still under development and therefore not open source to compile for your own crap" library by the carambola people
2014-07-22T14:41:35 < karlp> or, you know, don't use that code.
2014-07-22T14:41:56 < karlp> 3.7 is just what you got on an older tree, goign to an older tree would be easier than trying to downgrade a current tree.
2014-07-22T14:42:14 < Tectu_> karlp, not sure what you mean.
2014-07-22T14:42:33 < Tectu_> karlp, so the right way to do this is to recompile the entire image rather then just using the packagemanager like I would with my desktop linux?
2014-07-22T14:44:34 < karlp> if youð're experimenting with openwrt and your own devices, I would absolutely expect you to have a buildroot

2014-07-22T14:55:35 < Tectu_> scrts_w, same here
2014-07-22T14:55:55 < scrts_w> for WiFi I am now considering CC3200
2014-07-22T15:02:10 < Tectu_> ah, I've seen a post that there is a refresh of the CC3000 series
2014-07-22T15:02:12 < Steffanx> look through the source a bit.. was suprised how "open sores" it actually is.
2014-07-22T15:02:42 < Steffanx> expected some pre-compile lib.

2014-07-22T16:47:11 < dongs> well, i mean,, that many bytes vs like 10-200
2014-07-22T16:47:42 < jpa-> atleast stm32f4 does up to 64k

2014-07-22T17:07:16 < dongs> can I count edges on a scope
2014-07-22T17:08:36 < dongs> k has positive pulse count
2014-07-22T17:08:47 < talsit> hey dongs, what's the max rate i can drive the encoder part of an STM32F103?
2014-07-22T17:09:08 < dongs> talsit: um, pretty sure it works off say bldc running at 10krpm
2014-07-22T17:09:21 < dongs> so, probably faster than you need to :)
2014-07-22T17:09:33 < talsit> i have a 50MHz quadrature output
2014-07-22T17:09:39 < talsit> so... maybe not fast enough
2014-07-22T17:09:42 < dongs> that, yeah
2014-07-22T17:09:58 < dongs> doesnt TIMx run at 36MHz on F1
2014-07-22T17:10:05 < dongs> there's 1 at 72mhz?
2014-07-22T17:12:24 < jpa-> F1 timers only accept external inputs up to 36MHz or Fclk/2, whichever is lower

2014-07-22T17:17:57 < dongs> wow this is amazing
2014-07-22T17:18:17 < dongs> so, not only can I add 'measure these edges' to scope, i can also tell it to 'gate' measurement only between cursors
2014-07-22T17:18:38 < dongs> so I can capture something like 30k clockout pulses at 5M sample depth and it'll count all of htem exactly
2014-07-22T17:19:08 < dongs> fgt says my shit doesnt work, scope screenshot proves otherwise :)

2014-07-22T21:33:13 < emeb> Can anyone explain what the problem is with using the ST StdPeriph I2C code?
2014-07-22T21:33:56 < emeb> ISTR there were some issues with interrupts that caused dongs and Laurenceb to re-write large chunks of it.
2014-07-22T21:40:38 < Laurenceb_> yes
2014-07-22T21:40:49 < Laurenceb_> there are some race conditions and stuff....
2014-07-22T21:40:59 < Laurenceb_> and the stop bit can jam on for no good reason
2014-07-22T21:41:26 < Laurenceb_> but there is nothing wrong with the StdPeriph code
2014-07-22T21:41:30 < Laurenceb_> its just very basic
2014-07-22T21:43:43 < emeb> Laurenceb_: is it a HW issue that the StdPeriph doesn't account for?
2014-07-22T21:43:53 < Laurenceb_> yes
2014-07-22T21:43:59 < emeb> Interesting
2014-07-22T21:44:12 < emeb> What version of STM32 did you see this on?
2014-07-22T21:44:19 < Laurenceb_> F1
2014-07-22T21:44:24 < emeb> Aha
2014-07-22T21:44:29 < emeb> I'm using an F373
2014-07-22T21:45:03 < emeb> wonder if it's different from F1 - I know it's different from F4

2014-07-22T23:58:19 < qyx_> i failed right on the beginning - wrong xtal
--- Day changed Wed Jul 23 2014
2014-07-23T00:09:38 < zyp> no

2014-07-23T00:20:36 < zyp> they are all usb compatible
2014-07-23T00:20:39 < zyp> :p
2014-07-23T00:20:56 < zyp> there are pretty much just two variants
2014-07-23T00:20:59 < ds2> ah so the ARM core has native USB and talks to it that way? :D
2014-07-23T00:21:14 < zyp> dwc_otg which is a synopsys core, and a much simpler device only core
2014-07-23T00:29:50 < bvernoux> qyx_: the only resistor you need for FS is 22ohm on D+ & D- line
2014-07-23T00:30:05 < bvernoux> no pullup or pulldown or anything else

2014-07-23T02:19:59 < karlp> so, you're name is in gold stars now? ;)
2014-07-23T02:20:27 < karlp> or, should I say, "hurhur, my mum had that driver before you were even i2cing...."....
2014-07-23T02:20:39 < emeb> yeah - it's a truly astonishing thing. :P
2014-07-23T02:20:58 < karlp> so, how abou tthe rest of the sdr? you were doing some HF sdr with this board right?
2014-07-23T02:21:09 < emeb> "can copy example code from the eval board drivers"
2014-07-23T02:21:17 < emeb> yeah
2014-07-23T02:21:24 < emeb> still working on that part of it
2014-07-23T02:21:48 < karlp> more than me, spent half the night dreaming about going to work and hacking straight onto a project,
2014-07-23T02:22:00 < karlp> spent half the morning thinking, "maybe this isnt' going far enough"
2014-07-23T02:22:03 < emeb> got frequency control for the tuner. Now hooking up the QSD outputs to the SDADC inputs
2014-07-23T02:22:23 < emeb> heh
2014-07-23T02:22:27 < emeb> always go too far
2014-07-23T02:22:33 < karlp> half the afternoon thinking, "will I? should I? maybe I will?" and then a final hour startering to rip the guts out
2014-07-23T02:22:56 < karlp> yeah, think it's gotten far enough that a slash and burn is better
2014-07-23T02:23:30 < karlp> and all I didi was leave late with a pile of uncompilable code and head for a beer anyway ;)
2014-07-23T02:24:17 < emeb> more than a lot of folks accomplish in a day
2014-07-23T02:24:41 < karlp> hrm,
2014-07-23T02:24:45 < karlp> I come here to be inspired
2014-07-23T02:24:54 < karlp> haven't gotten much real work done in maybe a month
2014-07-23T02:25:10 < karlp> need to reach further
2014-07-23T02:25:30 < karlp> today I maybe finally started, but it's also feeling like I may have just burnt down the farm
2014-07-23T02:25:52 < emeb> what projects you have in the works?
2014-07-23T02:28:07 < Laurenceb> <hesperaux> how do I STM32 USB

2014-07-23T02:28:23 < hesperaux> why did you lolled guy?
2014-07-23T02:28:33 < karlp> emeb: work stuff, big ball of standalone/cloud analysis of power metering
2014-07-23T02:28:46 < Laurenceb> because to answer that could be a thesis length essay
2014-07-23T02:28:57 < karlp> some of it's great, some of it would have benefitted from me having a colleague instead of just the wall to talk to
2014-07-23T02:29:14 < karlp> (it's not _bad_, it's just that I'd love it to be better)
2014-07-23T02:29:18 < emeb> karlp: sounds potentially interesting
2014-07-23T02:29:31 < hesperaux> laurenceb have you used USB on an STM32 before?
2014-07-23T02:29:54 < hesperaux> i need to know where to start. I just want to write a very simple driver to interface a PC with an STM32. Doesn't necessarily have to fit a USB class
2014-07-23T02:30:12 < karlp> I'd send your our website, except that its embarrassing, and I can't share a demo account that we _need_ to have available
2014-07-23T02:30:34 < karlp> had a little reshuffle, hopefully we'll get a website soon that I can be proud of
2014-07-23T02:30:50 < ds2> is that chip working well enough that you see the FCC's RDF vans circling your house?

2014-07-23T02:32:33 < emeb> but as it stands now the output is just a 3.3V CMOS square-wave, so it's not going to be worse than your usual oscillator chip
2014-07-23T02:32:51 < ds2> emeb: doesn't that thing cover some 'interesting' bands?
2014-07-23T02:33:20 < emeb> ds2: the CMOS output one goes from ~ 3.3MHz - 160MHz continuous
2014-07-23T02:33:40 < emeb> the ones with LVDS/PECL outputs can go as high as 1.4GHz
2014-07-23T02:33:45 < ds2> emeb: isn't 30-50 one of those special bands?
2014-07-23T02:34:18 < emeb> ds2: dunno - what's special about it? I don't TX there.
2014-07-23T02:34:28 < ds2> above 50 is ham/tv/fm/rc stuff
2014-07-23T02:34:34 < ds2> emeb: mil/gov users
2014-07-23T02:34:49 < emeb> eh. mil/gov users go where they want.
2014-07-23T02:35:02  * karlp cries, I can't find a single document on the company website I' mhappy with :|
2014-07-23T02:36:10 < emeb> hesperaux: at the risk of opening up a can of worms, I'd suggest you grab the ST USB libraries for the STM32 family you're using and study the example code.
2014-07-23T02:36:31 < hesperaux> emeb, I wasn't able to locate them. Do you have a link?
2014-07-23T02:36:59 < emeb> hesperaux: this is your first challenge. Find the USB libraries. Hint - they're on the ST.com website.
2014-07-23T02:37:06 < hesperaux> lolk
2014-07-23T02:37:09 < ds2> hehe
2014-07-23T02:37:25 < emeb> If you can't get that far then you'll have a lot more troubles.
2014-07-23T02:37:29 < ds2> emeb: is that like saying... free devkit...hint, they are somewhere in the AZ desert?
2014-07-23T02:37:53 < emeb> ds2: :) the ST.com site is not well organized.
2014-07-23T02:38:05 < ds2> but the saguros are?
2014-07-23T02:38:07 < ds2> ;)
2014-07-23T02:39:52 < emeb> ds2: the saguaros are massing on the borders. the invasion starts soon.
2014-07-23T02:40:42 < hesperaux> it really isn't
2014-07-23T02:40:51 < hesperaux> so far i've found a virtual com port driver
2014-07-23T02:41:21 < emeb> hesperaux: which family of stm32 you using?
2014-07-23T02:41:33 < hesperaux> stm32f072rb

2014-07-23T02:42:59 < hesperaux> luckily this thing doesn't have to do much
2014-07-23T02:43:08 < hesperaux> i'll tell the arm compiler to optimize for size
2014-07-23T02:43:15 < emeb> Look inside the Projects dir - should be plenty of examples.
2014-07-23T02:43:16 < mervaka> level 2

2014-07-23T02:43:23 < ds2> bah...limits
2014-07-23T02:43:23 < mervaka> is best for size
2014-07-23T02:43:33 < mervaka> level 3 unrolls shit
2014-07-23T02:43:40 < ds2> the only limit is your imagination

2014-07-23T02:44:13 < hesperaux> it "supersedes" this library

2014-07-23T02:45:02 < hesperaux> it's like 20 million pages
2014-07-23T02:45:06 < mervaka> yup
2014-07-23T02:45:18 < hesperaux> i started reading it one day, and decided I was being stupid
2014-07-23T02:45:18 < emeb> and of course every MCU has a different way to do it
2014-07-23T02:45:22 < mervaka> i need a mofoing holiday
2014-07-23T02:45:40 < emeb> so what you learn one place doesn't quite fit when you go somewhere else
2014-07-23T02:45:51 < hesperaux> STM32Cube includes the STM32CubeMX which is a graphical software configuration tool that allows generating C initialization code using graphical wizards.
2014-07-23T02:45:51 < hesperaux> It also comprises the STM32CubeF0 platform which includes the STM32Cube HAL (an STM32 abstraction layer embedded software, ensuring maximized portability across STM32 portfolio), plus a consistent set of middleware components (RTOS, USB, FatFS and STM32 touch sensing). All embedded software utilities come with a full set of examples.
2014-07-23T02:45:58 < hesperaux> hmm.
2014-07-23T02:46:06 < emeb> forget that cube crap for now
2014-07-23T02:46:10 < mervaka> learn the descriptors of the classes you want, and how everything fits together
2014-07-23T02:46:14 < hesperaux> they recommend it for new designs
2014-07-23T02:46:16 < emeb> just go with the old libs
2014-07-23T02:46:19  * hesperaux doesn't know
2014-07-23T02:46:31 < hesperaux> i'll take your advice
2014-07-23T02:46:43 < mervaka> yeah, keep it old school
2014-07-23T02:46:57 < emeb> if you still want to screw with it after you get the old libs working then you'll be able to tweak what you've got
2014-07-23T02:47:50 < mervaka> emeb: got a project going at home too, a bass amp
2014-07-23T02:47:58 < mervaka> although shelved while it's awesome weather
2014-07-23T02:48:06 < hesperaux> my application is to bridge an NRF 2.4GHz transceiver to usb for linux. Should I use the CDC or HID class, which do you think?
2014-07-23T02:48:34 < mervaka> HID is always low bandwidth
2014-07-23T02:48:37 < mervaka> iirc
2014-07-23T02:48:49 < emeb> you can push it if you up the interrupt rate
2014-07-23T02:48:55 < mervaka> hmm
2014-07-23T02:48:57 < emeb> but CDC is probably a better choice
2014-07-23T02:49:15 < emeb> CDC is a less heavily formatted class
2014-07-23T02:49:26 < emeb> HID has all sorts of crazy reports, etc.
2014-07-23T02:49:35 < emeb> CDC is just a raw data pipe
2014-07-23T02:49:55 < mervaka> right, i'm gonna shoot off again, its late

2014-07-23T03:33:18  * hesperaux watches it
2014-07-23T03:33:24 < emeb> no one ever showed that poor slob how to do drag soldering
2014-07-23T03:33:33 < hesperaux> i'm excited to watch this
2014-07-23T03:33:44 < hesperaux> does he pour molten solder all over it?
2014-07-23T03:33:47 < hesperaux> please tell me he does
2014-07-23T03:33:50 < emeb> nope
2014-07-23T03:33:54 < hesperaux> hmm
2014-07-23T03:33:57  * hesperaux is intrigued
2014-07-23T03:34:04 < emeb> he hand solders a huge bead on all four sides
2014-07-23T03:34:21 < emeb> then heats it up and smacks the board on the table to shake off the excess & bridges
2014-07-23T03:34:27 < hesperaux> oh i've seen that before
2014-07-23T03:34:31 < hesperaux> in a chinese video

2014-07-23T03:34:46 < emeb> drag soldering is so fricken easy
2014-07-23T03:34:56 < hesperaux> indeed
2014-07-23T03:34:57 < qyx_> if he used proper flux in generous amount, it would be under 1 minute
2014-07-23T03:35:07 < emeb> tack corners, apply flux, drag, done.
2014-07-23T03:35:09 < hesperaux> and it's not like you can't use solder braid to fix

2014-07-23T05:48:15 < dongs> hmm
2014-07-23T05:48:20 < dongs> my battery voltage measure is failing
2014-07-23T05:48:26 < dongs> i used 1M:1M resistor divider
2014-07-23T05:48:56 < dongs> multimeter says 4.17V output from divider 1.855V
2014-07-23T05:49:30 < dongs> which, if itwas 2:1 divider as I expected, should mean battery is at 3.71...
2014-07-23T05:53:00 < Lux> prob too low impedance on the measuring input ?
2014-07-23T05:53:17 < GargantuaSauce> yeah the impedance of the adc is on the order of 100k or so i believe
2014-07-23T05:54:12 < dongs> well, i wanted to use 1M so i dont draw too much current from divider
2014-07-23T05:54:17 < dongs> should I drop down to like 100k:100k?
2014-07-23T05:54:23 < dongs> or how do i compensate
2014-07-23T05:54:42 < dongs> GargantuaSauce: so adc also becomes part of divider?
2014-07-23T05:54:47 < GargantuaSauce> basically yes
2014-07-23T05:54:55 < GargantuaSauce> an extra resistance to ground and/or vcc
2014-07-23T05:55:02 < Lux> yeah, you just have to figure out the impedance
2014-07-23T05:55:39 < GargantuaSauce> could use an amplifier or use notably smaller resistors, i would say a few tens of k
2014-07-23T05:55:56 < Lux> or just use a lower samplerate
2014-07-23T05:56:04 < dongs> im already very low
2014-07-23T05:56:13 < dongs> i think lowest it can go. because i dont really care about this value more often than a second
2014-07-23T05:56:43 < Lux> then it should be around 1 meg ohm
2014-07-23T05:57:01 < dongs> waht is, ADC impedance?
2014-07-23T05:57:07 < Lux> there is a equation for that in the datasheet
2014-07-23T05:57:07 < dongs> is this shit in datasheet or wat
2014-07-23T05:57:43 < dongs> ooo
2014-07-23T05:57:46 < dongs> tabvle 47
2014-07-23T05:57:47 < dongs> or someshit
2014-07-23T05:57:49 < dongs> amazeeeee
2014-07-23T05:58:34 < Lux> can't you just add a tiny cheap opamp ?
2014-07-23T05:58:42 < dongs> haha no
2014-07-23T05:58:47 < dongs> its just battery voltage
2014-07-23T05:59:18 < dongs> hmm, what does ADC run at by default?
2014-07-23T05:59:19 < dongs> 14mhz?
2014-07-23T06:00:57 -!- bvsh [~bvsh@unaffiliated/bvsh] has quit [Ping timeout: 250 seconds]
2014-07-23T06:01:18 < Lux> i guess you could calculate the resistance from just taking a few measurements at different voltages and then use a linear fit to calculate the correlation
2014-07-23T06:02:26 < GargantuaSauce> could also maybe cheat with a capacitor
2014-07-23T06:03:07 < GargantuaSauce> but at least looking at the f030 datasheet it doesn't go above 50k
2014-07-23T06:03:25 < GargantuaSauce> dunno if other lines are the same
2014-07-23T06:03:34 < Lux> like only turn on the adc for a short time and let the cap buffer ?
2014-07-23T06:03:39 < GargantuaSauce> yeah :/
2014-07-23T06:03:45 < Lux> hacky
2014-07-23T06:04:19 < dongs> well fuck
2014-07-23T06:04:23 < GargantuaSauce> not an awesome solution but i am not sure software compensation is much better
2014-07-23T06:04:28 < dongs> ill just go to 10k:10k divideR??
2014-07-23T06:04:35 < GargantuaSauce> yeah that sounds like the best course of action
2014-07-23T06:04:45 < dongs> but isnt that gonna drain battery
2014-07-23T06:05:00 < dongs> time for wolframalpha
2014-07-23T06:05:19 < Lux> 0.3mA at 6V
2014-07-23T06:05:25 < dongs> 4.2 would be max
2014-07-23T06:05:31 < dongs> how do i calculated that
2014-07-23T06:05:38 < GargantuaSauce> uh v=ir?
2014-07-23T06:05:40 < dongs> thx
2014-07-23T06:05:41 < Lux> I=u/R ;)
2014-07-23T06:06:14 < Lux> so it's 0.21mA
2014-07-23T06:06:21 < dongs> thats a fair bit
2014-07-23T06:06:22 < GargantuaSauce> its too bad the adc pins arent 5v tolerant, otherwise you could do something really wonky like add a lowside fet to the divider
2014-07-23T06:06:36 < dongs> if they were 5V tolerant i could hjave just fed battery directly to it
2014-07-23T06:06:52 < Lux> 100k+100k at a low sample rate should work too
2014-07-23T06:07:17 < dongs> i dont really wanna solder this shit twice
2014-07-23T06:07:21 < dongs> lemme see what I have < 100k > 50k
2014-07-23T06:07:36 < dongs> got 33 and 47
2014-07-23T06:08:21 < Lux> I'm pretty sure the adc can have like 1M input impedance
2014-07-23T06:09:21 < dongs> k ill try 33k
2014-07-23T06:09:39 < ds2> is it going beyond 4.2V?
2014-07-23T06:09:51 < dongs> nup
2014-07-23T06:10:10 < ds2> I don't care if a charger makes the voltage goes up; I just care it never goes beyond 4.2V ;)
2014-07-23T06:10:25 < ds2> whats the current into the battery?
2014-07-23T06:10:57 < dongs> from charger? its 1A but i have it limited to ~450 right now
2014-07-23T06:11:06 < dongs> mostly cuz i was too lazy to  calculate ISET resistor

2014-07-23T06:13:42 < ds2> what's the capacity of the battery?
2014-07-23T06:14:12 < dongs> just testing with a random cell i got here
2014-07-23T06:14:16 < dongs> it will be 3-5Ah when done
2014-07-23T06:14:21 < dongs> now its 350mAh
2014-07-23T06:14:24 < ds2> ah
2014-07-23T06:14:44 < ds2> had someone tried to charge a 200mAH battery at nearly 1A
2014-07-23T06:14:54 < dongs> i ordered some of those 808 keychain cams
2014-07-23T06:15:04 < dongs> and they sent me a pack of replacement btts
2014-07-23T06:15:11 < dongs> like 6 or something
2014-07-23T06:15:22 < dongs> ds2: its 20C discharge, so i guess its probly ok to charge it at ~1C
2014-07-23T06:15:29 < dongs> without trashing it too badly :)
2014-07-23T06:15:46 < dongs> but yeah, when 3-5Ah stuff is in final, its ok to do at ~1A
2014-07-23T06:15:54 < ds2> depends on how hot it got ;)
2014-07-23T06:16:01 < dongs> battery?
2014-07-23T06:16:03 < dongs> it didnt.
2014-07-23T06:16:26 < ds2> that's good :D

2014-07-23T08:10:10 < upgrdman> why not just use some diodes to drop voltage, and connect it to the ADC pin? no quiescent current, and account for the diode drops in software.
2014-07-23T08:10:22 < upgrdman> like 2 silicon diode should do the trick
2014-07-23T08:10:49 < dongs> heh
2014-07-23T08:11:07 < upgrdman> bad idea?
2014-07-23T08:11:32 < dongs> it sounds legit, but wouldnt then i have to calibrate each device
2014-07-23T08:11:51 < dongs> unless diode drop is eaxct always
2014-07-23T08:12:47 < upgrdman> never tried it, but i dont think diode drops vary much if you don't draw much current. (vary much from batch to batch... will vary with different diode brands, models, etc.)
2014-07-23T08:13:14 < dongs> this charger takes forever to taper off charge

2014-07-23T08:15:00 < dongs> been a while sitting at like 4.19V
2014-07-23T08:15:04 < dongs> and drawing almost no current
2014-07-23T08:16:08 < jpa-> dongs: multimeter loads the voltage divider more than the STM32 ADC; just have a 100nF cap on the lines and you should be fine for one measurement per second with 1Mohm divider
2014-07-23T08:16:51 < dongs> i thought i added cap but apprently i forgot

2014-07-23T08:44:30 < GargantuaSauce> upgrdman: put a diode in series with a big resistor, across a voltage
2014-07-23T08:44:35 < GargantuaSauce> and measure the voltage across the diode
2014-07-23T08:45:11 < GargantuaSauce> it won't be what you think it is.
2014-07-23T08:46:27 < jpa-> how do you know what he thinks?
2014-07-23T08:46:55 < GargantuaSauce> telepathy
2014-07-23T08:46:59 < jpa-> besides, with diodes, one could always enable the 50kohm pulldown on the pin when measuring
2014-07-23T08:47:10 < jpa-> and disable it otherwise
2014-07-23T08:47:25 < GargantuaSauce> the pin can't be >aVcc
2014-07-23T08:51:41 < upgrdman> GargantuaSauce: i know they not exactly 0.7V or 0.65V or whatever. but if you take a particular model of diode, i would think that the voltage drop across it would be ~constant when only drawing a small amount of current
2014-07-23T08:51:54 < GargantuaSauce> it would also be very small
2014-07-23T08:51:59 < upgrdman> besides, with a resistive voltage divider, is dongs going to use precision laser trimmer resistors? :)
2014-07-23T08:52:09 < upgrdman> trimmed*
2014-07-23T08:52:50 < jpa-> upgrdman: if there is no load resistor, the voltage drop across a diode will be quite random, and only like 0.1-0.2V
2014-07-23T08:53:04 < upgrdman> hmmm
2014-07-23T08:53:28 < upgrdman> ok :(
2014-07-23T08:53:32 < upgrdman> how about a zener?
2014-07-23T08:53:34 < jpa-> resistors are 1% easily, your diode solution (with two diodes) can have an uncertainty of 0.4V or more => 10% error
2014-07-23T08:53:49 < jpa-> much the same
2014-07-23T08:53:54 < upgrdman> ok
2014-07-23T08:54:33 < jpa-> conditionally turning on the 50kohm pull-down would work, but like GargantuaSauce says, it would load the ESD diodes when the pull-down is off (not necessarily too bad, but not a great design either)
2014-07-23T08:55:03 < GargantuaSauce> well and potentially when they're on. and it would make the result meaningless

2014-07-23T15:53:22 < karlp> heh, gcc lets you declare constructor attributes on functions.
2014-07-23T15:54:04 < zyp> which?
2014-07-23T15:54:26 < zyp> you mean the initialization stuff?
2014-07-23T15:54:40 < zyp> if so, that's normal

2014-07-23T15:55:24 < zyp> «The constructor attribute causes the function to be called automatically before execution enters main (). Similarly, the destructor attribute causes the function to be called automatically after main () completes or exit () is called. Functions with these attributes are useful for initializing data that is used implicitly during the execution of the program.»
2014-07-23T16:05:31 < jpa-> yeah, basically just a way to add C functions to the C++ static init/finalizer table
2014-07-23T16:15:43 < karlp> also this sort of thing: http://balau82.wordpress.com/2010/10/06/trace-and-profile-function-calls-with-gcc/
2014-07-23T16:15:57 < karlp> not sure if you should really try and _use_ those attributes in normal use though
2014-07-23T16:16:37 < zyp> of course not, it's for profiling

2014-07-23T21:55:14 < Steffanx> Probably all black magic to me, but still curious.
2014-07-23T21:56:13 < emeb> Steffanx: Yeah - I'll post some source once I get closer to something usable.
2014-07-23T21:56:21 < Steffanx> ok, great :)
2014-07-23T21:56:31 < emeb> right now it's very ugly

2014-07-23T22:13:35 < aadamson> going to show my lack of education... if I wanted to add an external analog temp sensor to an stm32l1, I know how to electrically connect it, but someone mentioned an issue with *bandgap*... and I guess I need an education..

2014-07-23T22:13:52 < aadamson> it's a sensor that is good for -55C to +125 at .4C resolution
2014-07-23T22:14:03 < aadamson> so what does the bandgap comment mean/reference?
2014-07-23T22:14:20 < aadamson> obviously the device will be on an ADC channel

2014-07-23T22:22:18 < BrainDamage> a bandgap generator is a circuit that produces a voltage that has n derivatives constant ( typically 1-2) with temperature, and it's made by actually building a PTAT ( proportional to absolute temp ) fed into a component ( transistor ) that has the inverse curve with temp, lacking context perhaps he was referring to the PTAT circuit that would be inside the temp sensortoo?
2014-07-23T22:22:51 < BrainDamage> ( it's called bandgap generator because the output voltage is approx the same as the material's bandgap )
2014-07-23T22:23:37 < aadamson> hmm... I got the impression he meant... That the voltage coming from the external sensor would somehow need to take the internal vref (bandgap) of the stm32 into account...
2014-07-23T22:24:01 < aadamson> but I use a simple voltage divider for 2 other adc sensors and I don't have any issue with voltage accuracy
2014-07-23T22:24:16 < aadamson> after a smooth the values a little with a lpf
2014-07-23T22:24:19 < aadamson> .... NOW
2014-07-23T22:24:37 < aadamson> I also use the internal temp sensor on the processor and to correct it *I DID* have to apply the vref correction
2014-07-23T22:24:52 < aadamson> but I wouldn't think I'd have to to that with an external sensor?
2014-07-23T22:25:39 < aadamson> ya know, this is what makes it fun... only one way to find out... try it! :)
2014-07-23T22:25:57 < BrainDamage> perhaps currenct consumption of the device?
2014-07-23T22:26:07 < karlp> depends how stable your vdda is...
2014-07-23T22:26:07 < BrainDamage> as you load your voltage divider it'll sag the output
2014-07-23T22:26:15 < PaulFertser> aadamson: to use stm32's internal vref you must measure it and use calibration values from rom.
2014-07-23T22:26:23 < aadamson> I do that PaulFertser
2014-07-23T22:26:25 < karlp> you can use the measurement of the internal vref to calibrate adc readings if vdda isn't stable
2014-07-23T22:26:39 < aadamson> I used the sample code from the L1 temp example
2014-07-23T22:26:53 < aadamson> BrainDamage, yeah I'm thinking that will be the case as well
2014-07-23T22:27:11 < aadamson> I could watch vref and correct based upon swing... maybe that's what he was talking about
2014-07-23T22:27:25 < PaulFertser> aadamson: yes, I'm using temperature sensor on l152 too and it seems to work fine for the purpose, I use both calibration values for the vref and for the sensor itself.
2014-07-23T22:27:44 < aadamson> same PaulFertser ... on the L151
2014-07-23T22:28:38 < aadamson> Ok, thanks all, seems I was on the right track, just needing a little encouragement :)
2014-07-23T22:29:08 < aadamson> this is just a 48 pin part so vdda is connected to vcc.
2014-07-23T22:29:42 < aadamson> but using the internal rom correction against the reference on a 3.0v platform is how I correct the temp sensor so I'll do similar and see what I get... thanks agian!
2014-07-23T22:30:20 < aadamson> I've decided that the internal processor sensor is nothing more than a solar/sun sensor in my application :)
2014-07-23T22:30:37 < aadamson> works perfectly at night, but suck in bright daylight with any thermal heating... :)
2014-07-23T22:30:46 < aadamson> (not sure if the external is just going to do the same or not)

2014-07-23T22:59:19 < aadamson> I think I've just about got hardware where I want it.

2014-07-23T23:00:28 < aadamson> but prediction vs. actual was completely WRONG :)

2014-07-24T08:40:41 < PaulFertser> Regarding _sbrk check if the allocated memory is "overlapping" with the stack or not: there's another complication here. When using RTOS, stacks a per-process and e.g. FreeRTOS allocates them from its own heap, so this logic fails.
2014-07-24T09:13:10 < PaulFertser> Ended up adding plain _sbrk() version without these checks to my main.c. Since all the .o files are linked in before .a files, it overrides the version from libgloss (libnosys) all right.

2014-07-24T13:08:34 < metRo_> karlp: I'm programming a board with a stm32disco stlink
2014-07-24T13:08:52 < metRo_> but it only works if I power my board with the same stm32disco 3v
2014-07-24T13:09:46 < metRo_> if I use an external power source it says: http://pastebin.com/xrQYYxQK
2014-07-24T13:09:51 < jpa-> you have gnd connected, right?
2014-07-24T13:09:57 < metRo_> right
2014-07-24T13:10:20 < metRo_> I have the VDD_Target, Clock, GND, SWDIO, RESET connected
2014-07-24T13:10:31 < jpa-> how would one 3V supply be different from another, when they are both referenced to same ground?
2014-07-24T13:12:42 < metRo_> jpa-: when I'm using a external voltage I used a 3.3V source not a 3v as the stm32 disco
2014-07-24T13:13:02 < jpa-> shouldn't matter
2014-07-24T13:13:06 < metRo_> is it a propblem? I think I already used stlink with difernet power source
2014-07-24T13:13:23 < metRo_> I think it could be some problem with my board event if it works with the external power source
2014-07-24T13:13:42 < jpa-> measure NRST voltage to make sure it is high
2014-07-24T13:13:53 < jpa-> sometimes the processor pulls it low if the supplies are not ok
2014-07-24T13:18:19 < metRo_> jpa-: when have it connected to stm32disco stlink and powered with an external voltage?

2014-07-24T13:33:04 < madist> you've shown VDD_TARGET connected in the second diagram. That is an oversight ?
2014-07-24T13:33:18 < madist> or is it really connected ?
2014-07-24T13:33:54 < madist> nevermind.
2014-07-24T13:35:52 < metRo_> really connected
2014-07-24T13:38:01 < jpa-> does vdd_target even do anything on disco stlink?
2014-07-24T13:38:14 < jpa-> IIRC it is just a dummy pull-down or something

2014-07-24T19:45:55 < Laurenceb_> wtf
2014-07-24T19:46:04 < Laurenceb_> whats the correct number?
2014-07-24T19:46:11 < gxti> how should we know
2014-07-24T19:46:20 < Laurenceb_> for a micro sd card...
2014-07-24T19:46:33 < Laurenceb_> this is all abstracted anyway...

2014-07-24T19:46:44 < gxti> it doesn't really matter
2014-07-24T19:47:25 < gxti> hopefully windoze is as smart as lunix and uses only LBA partitioning when it's set
2014-07-24T19:48:56 < zyp> lots of heads on all the cylinders in your sd card
2014-07-24T19:49:02 < gxti> when i had to do some crap for partitioning virtual machine images, i defaulted to 64 heads and 32 sectors to get 1048576 byte cylinders
2014-07-24T19:50:13 < gxti> but ultimately it's all ignored as long as the partition table has LBA addresses

2014-07-24T23:36:15 < emeb> Steffanx: It's pretty neat - basic undersampling theory
2014-07-24T23:36:51 < emeb> it does have one significant flaw - images at odd harmonics of the LO frequency.
2014-07-24T23:37:12 < superbia> link
2014-07-24T23:37:33 < emeb> http://ebrombaugh.studionebula.com/radio/hfrx/index.html
2014-07-24T23:38:16 < emeb> so for example - when you tune to 1MHz, you can also have interference from signals at 3MHz, 5MHz, ... etc
2014-07-24T23:39:03 < emeb> So lowpass filters are needed prior to the QSD to remove signals you're not interested in which may interfere.

2014-07-25T06:41:54 < dongs> gxti: x5r or better

2014-07-25T06:42:42 < emeb_mac> ya
2014-07-25T06:42:45 < dongs> thats ok, since they're 0603 you can have a bunch of htem

2014-07-25T06:43:18 < gxti> the size matters more than the dielectric. but it's true you could just use more anyway.

2014-07-25T06:44:38 < emeb_mac> 10uf is what the datasheet says
2014-07-25T06:44:39 < gxti> hm, i've been using 4.7u ceramics and it seems ok. but i should probably look closer.
2014-07-25T06:45:17 < emeb_mac> and this was 0805 mlccs too.

2014-07-25T06:48:00 < emeb_mac> need to see if I can get some 0805 10uf 50V x5r to test on that circuit - higher voltage spec should help
2014-07-25T06:50:11 < dongs> pretty sure you wont

2014-07-25T10:36:15 < dongs> i already have enough 48lqfp trays
2014-07-25T10:36:25 < dongs> like a metric shitton
2014-07-25T10:37:07 < madist> trays are incredibly heavy.
2014-07-25T10:37:24 < madist> the tray:chip weight ratio must be something like 20:1
2014-07-25T10:37:47 < dongs> yea no shit
2014-07-25T10:38:06 < madist> why do those trays have to be so heavy ? they could save a ton of money shipping chips in lightweight trays, so there must be a very good reason why they're so heavy.
2014-07-25T10:39:26 < dongs> tyea just measured lqfp tray
2014-07-25T10:39:36 < dongs> it killed my 300gram scale so i did it in half
2014-07-25T10:39:44 < dongs> 204+207 gram
2014-07-25T10:39:53 < dongs> so ~400gram for just plastic for 250 chips
2014-07-25T10:40:41 < dongs> 2.29g for chip, apparenly

2014-07-25T13:22:48 < metRo_> Hi all
2014-07-25T13:23:00 < metRo_> anyone knows what VDD_TARGET on stlink does?
2014-07-25T13:23:10 < metRo_> I'm with a problem on my board and can't find it :s
2014-07-25T13:23:27 < rewolff> The intent was to measure the VDD of the target.
2014-07-25T13:23:54 < Tectu_> VDD_TARGET is quite crucial as far as I know
2014-07-25T13:24:08 < rewolff> And/or couple a kind of "VCCIO" of the programmer there so that the programmer provides the same io levels as the target expects....
2014-07-25T13:24:31 < rewolff> That's what I've deduced from what I see in the schematics and documentation.... .
2014-07-25T13:24:35 < rewolff> However.....
2014-07-25T13:24:40 < Tectu_> rewolff, isn't that just the normal VCC pin on the STLINK?
2014-07-25T13:24:44 < Tectu_> SWD/JTAG interface
2014-07-25T13:24:55 < rewolff> On STLINK that comes with discovery and/or nucleo boards....
2014-07-25T13:25:09 < metRo_> I'm using stlink that comes with stm32discovery board
2014-07-25T13:25:11 < rewolff> it is more or less not connected anywhere....
2014-07-25T13:25:13 < metRo_> I have this problem http://i.imgur.com/SokPSB4.png
2014-07-25T13:25:29 < rewolff> So.... I have never connected it when debugging my own boards....
2014-07-25T13:25:35 < madiz> Tectu_: no
2014-07-25T13:26:09 < metRo_> If i use the power from stm32discovery I can program it
2014-07-25T13:26:19 < metRo_> with 3.3v from an external source and I can't
2014-07-25T13:26:27 < metRo_> and I can't find anything wrong :s
2014-07-25T13:26:33 < Tectu_> madiz, where does one find a dedicated VCCIO or VDD_TARGET on the jtag connector?   http://www.support.code-red-tech.com/CodeRedWiki/HardwareDebugConnections?action=AttachFile&do=get&target=20pin.png

2014-07-25T13:27:21 < Tectu_> madiz, what discovery board do you use? I cannot remember that the programmer of the discovery boards come with a dedicated TARGET pin
2014-07-25T13:27:57 < rewolff> metro, I have the setup that you pictured under "does not work".
2014-07-25T13:28:08 < madiz> Tectu_: F4 Discovery
2014-07-25T13:28:09 < rewolff> I'm using an AMS1117....
2014-07-25T13:28:18 < rewolff> Yes, F4 discovery.
2014-07-25T13:28:28 < rewolff> 4 wires from discovery to target board.
2014-07-25T13:28:30 < Tectu_> The F407?
2014-07-25T13:28:32 < madiz> Tectu_: afaik there is a resistor in series with the VDD_TARGET so you can't possibly power anything from it.
2014-07-25T13:28:36 < madiz> yes.
2014-07-25T13:28:37 < metRo_> rewolff: I know it is supposed to work as I used this setup on other boards
2014-07-25T13:28:37 < rewolff> pin 2,3,4,5.
2014-07-25T13:28:39 < rewolff> yes.
2014-07-25T13:28:55 < rewolff> (me too 407 discovery).
2014-07-25T13:29:10 < Tectu_> metRo_, on your board, is VCC and VDD_TARGET connected internally?
2014-07-25T13:29:15 < metRo_> rewolff: but can't find what is wrong with that particular board I'm working right now
2014-07-25T13:29:23 < Tectu_> VIN and VDD_TARGET I mean
2014-07-25T13:29:44 < metRo_> rewolff: doesn't you connect VDD_TARGET?
2014-07-25T13:29:57 < rewolff> Nope.

2014-07-25T13:30:50 < rewolff> I scrolled back in my STLINK window to try and find the "VDDtarget is 3295 mV" it reported with an open pin, but
2014-07-25T13:31:01 < rewolff> teh scrollback is too short. (only 2000 lines).
2014-07-25T13:32:07 < rewolff> VDD target pin on the SWD connector on the discovery board is at 0.00V. ....
2014-07-25T13:32:28 < metRo_> Tectu_: update the image: http://i.imgur.com/Mipb0jp.png
2014-07-25T13:32:38 < metRo_> Tectu_: yes
2014-07-25T13:33:25 < Tectu_> metRo_, what software are you using? windows + stlink flash utility or something?
2014-07-25T13:33:27 < Tectu_> or OpenOCD?
2014-07-25T13:33:31 < metRo_> openocd
2014-07-25T13:33:38 < Tectu_> log?
2014-07-25T13:33:38 < karlp> thought you fixed this yesterday?
2014-07-25T13:33:40 < metRo_> but tried stlink and the result is the same
2014-07-25T13:33:54 < Tectu_> metRo_, please paste the openocd log. Does it list the targets voltage?
2014-07-25T13:33:59 < rewolff> What is "doesn't work"?
2014-07-25T13:34:38 < rewolff> Hmm. gotta go. Good luck!
2014-07-25T13:34:41 < Tectu_> rewolff, is your crystal sphere broken? ;-)
2014-07-25T13:35:31 < metRo_> Tectu_: http://pastebin.com/nShdVpcq
2014-07-25T13:35:51 < metRo_> karlp: needed to go out :/
2014-07-25T13:36:16 < Tectu_> metRo_, drop the tcl/ in the paths for once. not sure about those. My scripts are somewhere else
2014-07-25T13:36:32 < Tectu_> metRo_, did you try to hard-reset the device before you connect?
2014-07-25T13:36:36 < Tectu_> connect as in starting OpenOCD
2014-07-25T13:37:04 < metRo_> Tectu_: but openocd works ok if I power the board from stm32discovery board
2014-07-25T13:37:25 < Tectu_> right, good point
2014-07-25T13:37:51 < Tectu_> VCC and GND do not appear to be the problem
2014-07-25T13:38:19 < Tectu_> just out of the blue: how long are your cables? I know that this shouldn't be the problem as it works with the other way around but I start to run out of guesses
2014-07-25T13:38:19 < metRo_> the target voltage that openocd report is stlink voltage or my board voltage?
2014-07-25T13:38:30 < metRo_> 20cm
2014-07-25T13:38:45 < metRo_> but they work also with another board
2014-07-25T13:39:08 < metRo_> the board I'm workink on is from this guy project http://andybrown.me.uk/wk/wp-content/images//awreflow/schematic.pdf
2014-07-25T13:39:08 < Tectu_> by the way... are you sure that your AMS1117 is powerful enough to drive the board? probably you're close to current limit so as soon as the CPU fires up voltage drops? :P
2014-07-25T13:39:13 < metRo_> http://andybrown.me.uk/wk/2014/05/11/awreflow/
2014-07-25T13:39:26 < metRo_> I soldered it by hand so there could be some problem
2014-07-25T13:39:33 < metRo_> I'm trying to figure out where to look
2014-07-25T13:39:43 < Tectu_> no idea, sorry
2014-07-25T13:39:46 < metRo_> hmm
2014-07-25T13:40:00 < metRo_> ams should give 1A
2014-07-25T13:40:08 < metRo_> a lot more power that the stm32 disocvery board
2014-07-25T13:41:52 < metRo_> I got the power from a waveshar port103v board that works ok with the stm32disco stlink using the setup that with my board doesnt work

2014-07-25T22:03:05 < karlp> struct blah s = {0}; gives warnings about unitialized members.
2014-07-25T22:04:00 < zyp> naturally, if you have more than one member
2014-07-25T22:05:05 < qyx_> apple uses it, it must be good
2014-07-25T22:05:20 < karlp> its explicitly allowed in c99, with defined behaviour, so no, I don't want a warning.
2014-07-25T22:07:17 < jpa-> you can disable the warning
2014-07-25T22:07:58 < karlp> but then I won't get the warning for s = {blah, wop} with missing members ;)
2014-07-25T22:09:02 < jpa-> yeah
2014-07-25T22:09:11 < jpa-> part of the reason why = {}; is so nice :)
2014-07-25T22:09:15 < zyp> are you building in c99 mode then?
2014-07-25T22:10:44 < karlp> = {} isn't allowed, and zyp, yeah, it's a filed bug in both gcc and at least a mailing list item referring to the same bug on the clang mailing lists
2014-07-25T22:10:55 < karlp> it's actually recently fixed, but hasn't amde a gcc release yet

2014-07-26T00:21:24 < Tectu_> emeb, I just saw that
2014-07-26T00:21:55 < Tectu_> effractur, but the chip is internally exactly the same - just few peripherals? So when I have a working application with an F407 with RTC etc, it will work with the same code on the F405?
2014-07-26T00:22:07 < emeb> Should
2014-07-26T00:22:45 < emeb> the 405 and 407 are on the same data sheet, so likely if you're not accessing features that only the 407 has you should be fine.
2014-07-26T00:23:01 < effractur> y that will just work
2014-07-26T00:23:09 < Tectu_> thanks
2014-07-26T00:23:14 < effractur> the 407 just has some extra peripherals
2014-07-26T00:23:41 < Tectu_> those STM32 somehow are ridiculously expensive I think.
2014-07-26T00:23:47 < emeb> and someone said that the 405 actually has some of the 407 peripherals
2014-07-26T00:23:54 < Tectu_> just disabled? :P
2014-07-26T00:23:59 < emeb> not even disabled
2014-07-26T00:24:04 < Tectu_> LOL?
2014-07-26T00:24:13 < emeb> sitting there - you can read/write the registers etc.
2014-07-26T00:24:20 < effractur> proly just not the pins
2014-07-26T00:24:26 < Tectu_> so it's like with your GPU card? You buy a cheaper and and it's the expensive one with some disabled shaders etc...
2014-07-26T00:24:35 < emeb> yep
2014-07-26T00:24:45 < effractur> y but still if you have the ethernetmac you are missing the pins/ports

2014-07-26T00:36:11 < gxti> yes Tectu_, it just changes the pci ID, and the driver treats it differently
2014-07-26T00:36:20 < Tectu_> gxti, interesting
2014-07-26T00:36:24 < superbia1> how would you do it Tectu_ ?
2014-07-26T00:37:34 < Tectu_> no idea, I have never thought about that. I was just curious that it is based on an analog solution
2014-07-26T00:45:16 < madist> don't the stlink boards have something similar ? resistors to set stlink version ? (though I think they don't actually use it)
2014-07-26T00:46:01 < gxti> if you already have an ADC it's an easy way to get multiple settings from one pin

2014-07-26T00:49:55 < Tectu_> sounds sane
2014-07-26T00:54:52 < Tectu_> have you ever used the STM32 internal RTC?
2014-07-26T00:54:56 < Tectu_> how accurate is it?
2014-07-26T00:55:01 < Tectu_> for an actual clock not enough I guess?
2014-07-26T00:55:49 < superbia1> ?
2014-07-26T00:56:26 < zyp> don't be dumb
2014-07-26T00:56:32 < zyp> the RTC is just a counter
2014-07-26T00:56:44 < zyp> the accuracy depends on whatever you're counting
2014-07-26T00:57:16 < zyp> or did you actually mean to run the RTC from LSI?
2014-07-26T01:05:59 < qyx_> not enough for clock?
2014-07-26T01:06:20 < superbia1> i smell a b o n e r
2014-07-26T01:06:21 < qyx_> if you use 20ppm crystal, it should deviate at most 1 second in about one day
2014-07-26T01:06:51 < qyx_> i assume it would be far less.. but didn't try
2014-07-26T01:08:09 < qyx_> 23:57 < zyp> or did you actually mean to run the RTC from LSI?
2014-07-26T01:08:10 < qyx_> lol
2014-07-26T01:08:27 < qyx_> ok
2014-07-26T01:09:05 < Tectu_> zyp, nope
2014-07-26T01:10:21 < zyp> well then
2014-07-26T01:10:38 < zyp> as I said, the RTC is just a counter, so the accuracy depends on the clock source
2014-07-26T01:11:47 < Tectu_> how was the naming of the crystals again? something like TXCO is temperature compensated, right?
2014-07-26T01:12:10 < superbia1> yup
2014-07-26T01:12:12 < qyx_> yes
2014-07-26T01:12:28 < qyx_> tcxo
2014-07-26T01:12:39 < superbia1> right :)
2014-07-26T01:13:24 < Tectu_> let's see what those cost :p
2014-07-26T01:13:52 < Steffanx> get some accurate 32.somethingKHz crystal to drive the rtc.
2014-07-26T01:25:56 < Tectu_> any crystal recommendation?
2014-07-26T01:38:45 < Steffanx> pick random one :)

2014-07-26T14:55:12 < AndreeeCZ> hello. I have a weird problem with my st32f429l: When i plug it in power (USB or direct 5V), it lights up, but doesnt do anything, no matter how many times I reset it. After ~20 attempts, it lights up and works normally, then i can reset it any number of times and it still works. What could be the cause of this?
2014-07-26T14:55:20 < AndreeeCZ> By reset i mean the reset button

2014-07-26T18:36:42 < scrts> Q regarding Gerbers: I've sent the files to the PCB manufacturer, but they came back with a different stack-up offering, because the can't do the requested one. I've replied saying OK, if the track impedance doesn't change. THen they replied what impedance do I want, so I've said 50ohm single ended and 100ohm differential. Then they asked which particular signals has this impedance? Is this normal? How do you guys do it?
2014-07-26T18:38:26 < jpa-> i would have just checked the impedance myself based on the new stackup
2014-07-26T18:39:02 < jpa-> the behaviour of fab house seems normal, usually a board only has a few impedance matched signals
2014-07-26T18:39:57 < jpa-> (i bet the guy at the other end is going "wtf is this dude doing sending us these ridiculous stacks and then demanding us to check his impedances" ;)
2014-07-26T18:43:44 < qyx_> you should recompute impedances based on their offering, change gerbers and resend them
2014-07-26T18:45:18 < scrts> hmm, ok
2014-07-26T18:45:24 < scrts> thanks

2014-07-26T18:47:33 < jpa-> well, if you want blind vias or something it is always just "specify your stackup and hope that it is something that they can do"
2014-07-26T18:48:11 < jpa-> of course world would be better if the board houses provided the info on their websites, but for some reason that rarely happens
2014-07-26T18:48:30 < emeb_mac> I understand that it's possible. Just that I've never used a PCB fab that wasn't a shared panel, so custom is not an option.

2014-07-26T19:19:46 < emeb_mac> eating can wait
2014-07-26T19:20:29 < jpa-> but i should probably plan before i code and i don't feel like planning
2014-07-26T19:20:43 < Tectu_> make your wife do the food thing
2014-07-26T19:20:50 < Tectu_> and do the planning
2014-07-26T19:20:53 < Tectu_> what ever that would be
2014-07-26T19:20:58 < jpa-> she's away hunting reindeer
2014-07-26T19:21:15 < emeb_mac> this is why .fi is awesome
2014-07-26T19:21:38 < jpa-> because i starve? i don't agree
2014-07-26T19:21:50 < emeb_mac> because women hunt reindeer
2014-07-26T19:22:20 < Tectu_> emeb_mac, I was left under the impression that it was just some common saying rather than the truth
2014-07-26T19:22:23 < jpa-> oh well, she's hunting them with a car so i guess it doesn't quite count.. we don't actually hunt reindeer in finland, just regular deer
2014-07-26T19:22:35 < emeb_mac> aha
2014-07-26T19:22:42 < Tectu_> "my wife is hunting reindeer" -> "she paints her nails"
2014-07-26T19:22:46 < jpa-> the reindeer are owned by people so they wouldn't quite appreciate hunting them
2014-07-26T19:22:55 < emeb_mac> here if you hunt with a car you get in trouble
2014-07-26T19:23:05 < jpa-> Tectu_: no actually she is travelling in lapland with her brother :)

2014-07-26T19:25:02 < Tectu_> emeb_mac, I'm still not sure if two are two too many or one too much
2014-07-26T19:25:20 < jpa-> the bigger problem is that it's hot in finland now.. downstairs is barely tolerable, but the food is upstairs
2014-07-26T19:26:13 < Tectu_> is zyp still in dongsland?
2014-07-26T19:26:17 < qyx_> hot? you mean like 20°C?
2014-07-26T19:26:32 < jpa-> 30°C actually

2014-07-26T19:26:40 < qyx_> pfff
2014-07-26T19:26:59 < Tectu_> jpa-, summer is shitty here this year. barely have 15°C. Usually we have at least 35°C this times of the year
2014-07-26T19:27:20 < jpa-> we had snow in june but july has been hot
2014-07-26T19:27:30 < Tectu_> jpa-, thinking of it again, I just forked you... why not sending your fork to do the foot job?
2014-07-26T19:27:50 < jpa-> Tectu_: look.. i'm not doing any more "foot jobs" for you!

2014-07-26T19:32:44 < Tectu_> emeb_mac, why do muricans still use imperial crap anyway?
2014-07-26T19:33:07 < Tectu_> jpa-, are you doing jewlery again?
2014-07-26T19:33:59 < emeb_mac> Tectu_: "This is how we've always done it"
2014-07-26T19:34:06 < jpa-> Tectu_: nah, something to cnc
2014-07-26T19:39:11 < emeb_mac> Tectu_: 'muricans have been arguing about converting to metric since the late 1700's
2014-07-26T19:39:47 < emeb_mac> One of the first presidents - Jefferson - thought we should use metric but it still didn't catch on.
2014-07-26T19:40:21 < Tectu_> emeb_mac, isn't it annoying you people too?
2014-07-26T19:40:40 < emeb_mac> yeah, but you deal.
2014-07-26T19:41:44 < jpa-> someone might ask europeans why we don't agree on a single language ;)
2014-07-26T19:42:10 < emeb_mac> lol
2014-07-26T19:42:57 < emeb_mac> even if we were to convert 100% tomorrow, there'd still be all this old hardware and documentation in english system
2014-07-26T19:43:10 < emeb_mac> so it's not like it would really save any trouble
2014-07-26T19:44:52 < BrainDamage> jpa-: pycam has a 3d preview function
2014-07-26T19:45:18 < jpa-> BrainDamage: sure, but it doesn't have a draw/paint function :)
2014-07-26T19:45:51 < BrainDamage> oh you mean that you want to draw and see a preview of the finished product at the same time?
2014-07-26T19:46:09 < jpa-> yeah, because it is really difficult to tell anything from a heightmap image
2014-07-26T19:46:15 < jpa-> it just goes against all intuition
2014-07-26T19:47:03 < jpa-> blender kind of does that, but not quite well
2014-07-26T19:47:13 < gnomad> SI units did not become popular until the 1800s.
2014-07-26T19:48:34 < BrainDamage> the french revolution spread the french metric system across eu
2014-07-26T19:48:43 < BrainDamage> but metric system != SI
2014-07-26T19:48:43 < madist> 0.1" headers will never go away.

2014-07-26T19:49:37 < gnomad> and while you can debate why SI units were not adopted in the US prior to WW-II, there was a very real reason not to adopt SI units in postwar years given the amount of tooling produced during the war in inch-units

2014-07-27T00:06:25 < Tectu_> when you have some tacticle button connected to your GPIO and you have some cap in parallel to the button and a pullup resistor, do you put the two latter directly next to the button or next to the GPIO pin?

2014-07-27T00:28:13 < Tectu_> does this look like a suitable cap to supply VBAT voltage?  http://ch.farnell.com/kemet/fc0h104zftbr24/kondensator-super-0-1f-5-5v-25r/dp/2362048

2014-07-27T00:29:48 < qyx_> isn't it too expensive for this purpose?
2014-07-27T00:30:40 < Tectu_> qyx_, it's a single piece that I am building so money does not matter
2014-07-27T00:30:44 < Tectu_> qyx_, are there better alternatives?
2014-07-27T00:31:03 < Tectu_> qyx_, I don't need a decoupling cap, obiously. I need something that can supply the backup voltage for max. 72hrs
2014-07-27T00:33:36 < qyx_> i would use standard lithium coin cell
2014-07-27T00:33:42 < qyx_> although it is not rechargeable
2014-07-27T00:34:05 < Tectu_> it is just too big for my purpose
2014-07-27T00:34:21 < Tectu_> and recharability doesn't really matter when the battery lasts at least 120 years anyway
2014-07-27T00:34:32 < qyx_> how much?
2014-07-27T00:34:45 < zyp> kondensator
2014-07-27T00:34:46 < Tectu_> (theoretically). The internal discharge is bigger than the actual current drawn throught the VBAT pin
2014-07-27T00:34:54 < Tectu_> qyx_, how much what?
2014-07-27T00:35:03 < qyx_> 120 years?
2014-07-27T00:35:47 < Tectu_> yeah. 240mA cell. Datasheet says that VBAT current is about 0.5uA
2014-07-27T00:36:42 < qyx_> there are smaller types if you want
2014-07-27T00:36:46 < Tectu_> anyway, the thing that I am worrying about the cap is about charging it. I place some resistor in series to VCC so it does not eat up all the power on powerup
2014-07-27T00:37:22 < Tectu_> but on the other hand the VBAT pin must be at voltage on powerup, no?
2014-07-27T00:37:31 < zyp> no
2014-07-27T00:37:35 < qyx_> no
2014-07-27T00:37:41 < zyp> vbat doesn't need to be powered at all
2014-07-27T00:37:51 < Tectu_> ah
2014-07-27T00:37:57 < zyp> vbat is only used when vdd is not powered
2014-07-27T00:38:17 < Tectu_> so I can simply put the supercap on the VBAT pin and a 1k resistor to VDD?
2014-07-27T00:38:20 < Tectu_> (to charge it)
2014-07-27T00:38:49 < zyp> no
2014-07-27T00:38:54 < qyx_> this 1k would also discharge it
2014-07-27T00:38:58 < zyp> you also need a diode
2014-07-27T00:40:16 < Tectu_> ah
2014-07-27T00:40:24 < Tectu_> but then I loose 0.3V (shottky)
2014-07-27T00:40:30 < Tectu_> 3V still fine?
2014-07-27T00:40:33 < zyp> so what?
2014-07-27T00:40:33 < qyx_> yes
2014-07-27T00:40:51 < Tectu_> would 0.7V drop still work too?
2014-07-27T00:40:51 < zyp> isn't the diode drop lower for low currents?
2014-07-27T00:40:54 < qyx_> you have exact minimum value in the DS
2014-07-27T00:41:07 < Tectu_> better check that out
2014-07-27T00:41:17 < Tectu_> zyp, it is
2014-07-27T00:41:19 < zyp> remember that the voltage goes down as the capacitor drains
2014-07-27T00:41:43 < zyp> Tectu_, yes, so as the capacitor fills up, the drop goes down and it fills some more, albeit slower
2014-07-27T00:42:19 < qyx_> vbat min is 1.65V, so you have some small margin
2014-07-27T00:42:38 < Tectu_> so I could even pick a standard 0.7V diode
2014-07-27T00:42:45 < qyx_> as you have to consider just 3V - 1.65V for the cap
2014-07-27T00:42:59 < qyx_> it is useful only when charged above 1.65
2014-07-27T00:42:59 < zyp> Tectu_, why would you?
2014-07-27T00:43:12 < Tectu_> zyp, I won't, just mentioned that one could :P
2014-07-27T00:43:18 < zyp> that would be dumb
2014-07-27T00:43:20 < Tectu_> I see
2014-07-27T00:43:24 < Tectu_> yep
2014-07-27T00:43:43 < Tectu_> anyway, has anybody of you already used the famous AP5100 DC/DC converter?
2014-07-27T00:43:49 < zyp> considering the drain curve of a capacitor, a lower voltage results in lower time to empty
2014-07-27T00:44:38 < qyx_> internets say 1F=0,2777mAh/V, so 1.35V at 0.1F is ~0.37mAh -> 750 hours
2014-07-27T00:45:02 < zyp> around a month
2014-07-27T00:45:27 < Tectu_> so my 0.1F will do just fine for a couple of days
2014-07-27T00:45:35 < qyx_> should do
2014-07-27T00:45:36 < zyp> should be fine
2014-07-27T00:45:47 < Tectu_> so shottky + resistor will do?

2014-07-27T05:56:31 < madist> qyx_: was that board reflowed or soldered with an iron ?
2014-07-27T06:03:45 < upgrdman> whats a reasonable via hole size and ring size when using a cheap board house?
2014-07-27T06:04:36 < jadew> upgrdman, they should specify that
2014-07-27T06:06:31 < jadew> if they don't, you can just send them the files and they'll mail you back if the holes are too small when they validate it
2014-07-27T06:09:13 < jadew> you could make everything impossible and send the design out, then you'll get a list of constraints :P
2014-07-27T06:09:28 < upgrdman> lol
2014-07-27T06:09:49 < ds2> depends on how cheap
2014-07-27T06:10:15 < jadew> location is also important, because cheap in china is better than expensive in here
2014-07-27T06:10:32 < jadew> but I suppose he means cheap in china, so pretty good quality

2014-07-27T06:26:29 < upgrdman> how safe is it to use the limits spec's by a cheap chinese board house? would it be safer to add a 20% (other %?) margin to get usable boards?
2014-07-27T06:27:49 < jadew> if you get 100% e-test it shouldn't matter
2014-07-27T06:27:59 < jadew> if they screw it up, they just re-spin it and you get more boards :P
2014-07-27T06:28:06 < upgrdman> k
2014-07-27T06:28:07 < qyx_> pretty safe, i usually send the baords to seed with limit specs and they are ok

2014-07-27T06:30:42 < upgrdman> how do they etest? i mean, they're not going to the trouble of a board of nails for the small quantity stuff
2014-07-27T06:31:06 < jadew> upgrdman, no idea, they probably have some bot do it

2014-07-27T06:33:19 < jadew> I'm kidding of course, it would be a hell job
2014-07-27T06:35:07 < jadew> I wonder if they'd accept to produce a board full of vias as close and as small as possible
2014-07-27T06:36:49 < jadew> it's got to take a while to drill several thousands holes
2014-07-27T06:38:03 < qyx_> i assume they will not do it for free
2014-07-27T06:38:20 < upgrdman> that looks like a soul-crushing place to work at.
2014-07-27T06:38:56 < jadew> upgrdman, you don't know that, midless job - you can think at ANYTHING ELSE while doing it

2014-07-27T20:19:14 < Theremin> Could someone, who was writing application using otg_fs usb driver for stm32 devices, help me? My problem is that during PENCHNG interrupt, PENA is 1. And then after interrupt routine exits, PENA is set by hardware(not by sw) to 0 trigerring another PENCHNG interrupt. I cannot move from this problem further. I would appreciate any hints :)

2014-07-27T22:43:56 < qyx_> is an idea of injecting current to SMPS feedback from DAC partially or totally dumb?
2014-07-27T22:45:00 < emeb> what for?
2014-07-27T22:45:14 < qyx_> to regulate smps output voltage
2014-07-27T22:45:43 < emeb> the smps doesn't regulate on its own?
2014-07-27T22:46:32 < qyx_> for "programming" the output voltage from mcu

2014-07-27T22:51:11 < emeb> should work, depending on where you inject.
2014-07-27T22:51:56 < qyx_> another possibility is doing the whole smps thing using the mcu
2014-07-27T22:52:11 < emeb> I've seen that done
2014-07-27T22:52:37 < emeb> lots of mcus are used for closed-loop power control
2014-07-27T22:53:07 < qyx_> that saves li-ion charger and smps switcher
2014-07-27T22:53:16 < qyx_> or combined smps charger
2014-07-27T22:53:31 < qyx_> should be replaceable with just n-mosfet
2014-07-27T22:53:34 < emeb> just use ADC and PWM
2014-07-27T22:54:00 < emeb> still need inductor, diode, cap
2014-07-27T22:54:08 < qyx_> i'll probably try this approach
2014-07-27T22:54:08 < qyx_> yep
2014-07-27T22:54:33 < qyx_> although there is a risk - upgradeable firmware
2014-07-27T22:54:33 < emeb> coming up with good loop filter system could be "fun"
2014-07-27T22:54:48 < emeb> learn all about PID control, stability, etc
2014-07-27T22:55:28 < qyx_> charging shouldn't need that tight control loop

2014-07-27T23:57:17 < bgamari> I've raised the interrupt priority of the interrupt I believe is now running but for some reason it's not being preempted by lower priorities
2014-07-27T23:57:39 < zyp> unless primask or some of the related stuff gets updated during handler execution
2014-07-27T23:57:51 < bgamari> zyp, yeah, I don't believe it does
2014-07-27T23:58:27 < bgamari> I've checked PRIGROUP
2014-07-27T23:58:46 < bgamari> it's 0x0 which should mean only the least significant bit is the subpriority

2014-07-28T13:36:12 < jpa-> timemob: so which switches were you building with?
2014-07-28T13:36:22 < timemob> and lunix toreballs officially declared GCC 4.90 shit
2014-07-28T13:36:33 < timemob> jpa, those two
2014-07-28T13:36:57 < timemob> cuz I just pasted code into existing project
2014-07-28T13:37:29 < Tectu> timemob, that's why we all don't use gcc but clang instead
2014-07-28T13:37:32 < timemob> and now I'm outside biking so I can't test without

2014-07-28T18:25:02 < gxti> i leave it on 0.25mm for routing. for non-metric pitch relying on the snap works well enough.
2014-07-28T18:25:22 < dongs> hm 0.25 is pretty coarse
2014-07-28T18:25:34 < zyp> depends on the track/space settings too

2014-07-28T21:48:07 < emeb> anyone got a link to that bitbang I2C code that dongs mentioned a while back?
2014-07-28T22:05:31 < Steffanx> how long is a while.. i think he actually linked to some random code a few times.
2014-07-28T22:05:57 < PaulFertser> emeb: https://github.com/multiwii/baseflight/blob/master/src/drv_i2c.c#L326
2014-07-28T22:06:11 < PaulFertser> This one? Oh, no, this's not bitbang.
2014-07-28T22:06:33 < PaulFertser> But he mentioned some clever/important tricks within that drv_i2c
2014-07-28T22:06:49 < emeb> yeah, remember that.
2014-07-28T22:07:17 < emeb> however - there is a preprocessor macro for SOFT_I2C that suggests the bitbang version may be in the same code base.
2014-07-28T22:07:42 < emeb> https://github.com/multiwii/baseflight/blob/master/src/drv_i2c_soft.c
2014-07-28T22:08:32 < Steffanx> And that's the code you were looking for?
2014-07-28T22:08:37 < emeb> I believe so
2014-07-28T22:08:59 < emeb> if not, it's equivalent.
2014-07-28T22:09:49 < Steffanx> i then i stop grepping my logs for you :P

2014-07-29T03:53:14 < dongs> you could probably overclock to ~100
2014-07-29T03:54:03 < upgrdman> looks nice
2014-07-29T03:54:17 < upgrdman> im just surprised there aren't many fast but small mcus.
2014-07-29T03:54:46 < upgrdman> seems like there is/would be a big market for DSP'ing and needing just a few pins to interface with a high res adc or other sensors

2014-07-29T07:27:58 < upgrdman> think i might actually step up to 2-layer boards. this was a bitch to route...  http://farrellf.com/temp/2layer_pcb.png
2014-07-29T07:28:42 < gxti> you mean 4? it's worth it.
2014-07-29T07:29:14 < upgrdman> well i thought i would do 2L first
2014-07-29T07:29:24 < upgrdman> it would be kinda sad to jump from 1L DIY to 4L
2014-07-29T07:29:54 < upgrdman> but ya, if i were to start over i would just do 4L and pay for it.
2014-07-29T07:38:37 < madist> is that diptrace ?
2014-07-29T07:38:50 < upgrdman> no.
2014-07-29T07:38:53 < upgrdman> geda pcb.
2014-07-29T07:39:03 < upgrdman> and yes, it sucks, and yes, i'm used to it :)
2014-07-29T07:40:31 < madist> i don't think i've ever heard anyone say they were happy with their drafting tools
2014-07-29T07:41:12 < upgrdman> sure, but geda takes annoying to a new level sometimes.
2014-07-29T07:41:17 < gxti> they all suck, but some REALLY suck
2014-07-29T07:41:29 < upgrdman> perhaps the most annoying is that it has no way to thermal a pad. it can only thermal a via.
2014-07-29T07:41:48 < gxti> isn't that the *opposite* of what you want? vias don't even need thermals
2014-07-29T07:42:04 < upgrdman> s/via/plated through hole
2014-07-29T07:42:14 < gxti> oh
2014-07-29T07:43:49 < upgrdman> so you have to manually draw traces for every pad you want to ground.
2014-07-29T07:44:06 < upgrdman> hence my ugly "T" and "X" ground pads

2014-07-29T07:48:08 < upgrdman> i also made my life hard by use 10/10mil and big-ish vias in hopes of getting good boards from cheap china fabs
2014-07-29T07:48:13 < ds2> is that altium?

2014-07-29T07:48:25 < gxti> is that orcad
2014-07-29T07:48:53 < dongs> thats like 30 minute routing job in altium
2014-07-29T07:49:12 < gxti> i probably would have dicked with it for hours anyway
2014-07-29T07:49:12 < dongs> (or even dicktrace
2014-07-29T07:49:23 < upgrdman> i actually download altidongs and poked it for a few minutes. too lazy to learn a new tool :( at least for now.
2014-07-29T07:49:36 < dongs> its worth it
2014-07-29T07:49:41 < upgrdman> i know
2014-07-29T07:49:57 < upgrdman> if i ever become a protroll i'm sure i will make the change.
2014-07-29T07:50:51 < dongs> even dicktrace would be an upgrade from geda

2014-07-29T17:19:11 < rewolff1> You mean you've got Linux up and running, and on the beagle you have eth0 AND eht1?
2014-07-29T17:19:20 < rewolff1> or it has eth0 configured instead of eth1?
2014-07-29T17:19:22 < Laurenceb_> nooooo
2014-07-29T17:19:34 < Laurenceb_> on my desktop i have eth0 and eth1
2014-07-29T17:19:40 < rewolff1> AH!
2014-07-29T17:19:58 < rewolff1> And there is a 'Private" network on your eth1
2014-07-29T17:20:11 < rewolff1> where teh beagle is...
2014-07-29T17:20:17 < Laurenceb_> yes

2014-07-29T17:22:00 < Laurenceb_> yeah i see it incoming

2014-07-29T17:23:06 < rewolff1> tcpdump -ni eth0 ?
2014-07-29T17:23:21 < rewolff1> possibly with "host 8.8.8.8" added.
2014-07-29T17:23:25 < Laurenceb_> yeah eeek
2014-07-29T17:23:34 < rewolff1> ?
2014-07-29T17:23:47 < Laurenceb_> yeah i see it
2014-07-29T17:24:01 < rewolff1> OK. What IP address? That of your Linux box, or that of the beagle ?
2014-07-29T17:24:06 < Laurenceb_> my box
2014-07-29T17:24:10 < Laurenceb_> going to 8.8.8.8
2014-07-29T17:24:12 < rewolff1> OK.
2014-07-29T17:24:19 < rewolff1> Looks good.
2014-07-29T17:24:25 < rewolff1> Then are the packets coming back?
2014-07-29T17:24:32 < Laurenceb_> how do i check?
2014-07-29T17:24:37 < Laurenceb_> they dont reach the beagle
2014-07-29T17:24:50 < rewolff1> No, in the tcpdump, you hsould also see the packets coming back.
2014-07-29T17:25:01 < Laurenceb_> oh wtf
2014-07-29T17:25:06 < Laurenceb_> lol i cont ping 8.8.8.8

2014-07-29T17:26:13 < Laurenceb_> ok wtf
2014-07-29T17:26:25 < Laurenceb_> clearly i have networking
2014-07-29T17:26:59 < Laurenceb_> lol maybe its being blocked
2014-07-29T17:28:04 < Laurenceb_> do i need dns as well?
2014-07-29T17:28:11 < Laurenceb_> on the BBB
2014-07-29T17:28:51 < rewolff1> No. we're working on IP level now.
2014-07-29T17:28:57 < Laurenceb_> ok
2014-07-29T17:29:02 < rewolff1> You pin 8.8.8.8 which needs no resolving.
2014-07-29T17:29:16 < Laurenceb_> something is blocking ping on my network
2014-07-29T17:29:52 < Laurenceb_> brb finding network admin
2014-07-29T17:30:01 < rewolff1> 16:29:54.048479 IP 192.168.36.1 > 8.8.8.8: ICMP echo request, id 7796, seq 3, length 64

2014-07-29T17:30:07 < rewolff1> request, reply...
2014-07-29T17:30:24 < rewolff1> looks like it. :-)
2014-07-29T17:31:06 < Laurenceb_> lol ping has been blocked on my network
2014-07-29T17:31:15 < Laurenceb_> so anyway
2014-07-29T17:31:15 < dongs> just install lunix
2014-07-29T17:31:24 < Laurenceb_> i need to update beaglebone
2014-07-29T17:31:26 < dongs> problem soolved
2014-07-29T17:31:43 < Laurenceb_> wget: bad address 'feeds.angstrom-distribution.org'
2014-07-29T17:32:12 < rewolff1> That sounds like a DNS problem.
2014-07-29T17:32:16 < Laurenceb_> yeah
2014-07-29T17:32:23 < Laurenceb_> so how do i setup DNS?
2014-07-29T17:32:39 < rewolff1> I'd say: Get IP working first.
2014-07-29T17:32:58 < rewolff1> telnet 173.194.65.105 80
2014-07-29T17:33:46 < rewolff1> First from your Linux box, let's be sure the network admin isn't blocking that either.
2014-07-29T17:34:12 < rewolff1> You should get "connected" and will get a 400 bad request if you type "quit" like I just did.
2014-07-29T17:35:36 < Laurenceb_> yeah that works on my desktop
2014-07-29T17:35:41 < Laurenceb_> but not on the BBB
2014-07-29T17:36:12 < rewolff1> Ok. Now we tcpdump with "host 173.194.65.105 " on the outgoing link on the linux box.
2014-07-29T17:37:42 < Laurenceb_> ok i see outgoing
2014-07-29T17:37:48 < rewolff1> And back?
2014-07-29T17:38:00 < Laurenceb_> yesa
2014-07-29T17:38:19 < rewolff1> Good. Now the question is: do you have the back packets on the other interface, going to the beagle.
2014-07-29T17:38:24 < Laurenceb_> so incoming isnt passed to the beagle
2014-07-29T17:38:41 < rewolff1> Did you check that already?
2014-07-29T17:39:08 < Laurenceb_>  IP 173.194.65.105.80 > 192.168.7.2.33298: Flags [S.], seq 254178
2014-07-29T17:39:13 < Laurenceb_> BBB is 7.2
2014-07-29T17:39:37 < rewolff1> So you DO see it on the BBB link, right?
2014-07-29T17:39:50 < Laurenceb_> yes
2014-07-29T17:39:59 < Laurenceb_> but i cant telnet from the beagle
2014-07-29T17:40:03 < Laurenceb_> it never connects
2014-07-29T17:40:12 < rewolff1> Then tcpdump on the BBB?
2014-07-29T17:40:17 < rewolff1> Is it installed?
2014-07-29T17:40:35 < Laurenceb_> yes
2014-07-29T17:41:07 < Laurenceb_> hmf
2014-07-29T17:41:13 < rewolff1> Don't forget the "host 173.... " on the tcpdump if you're logged in to the BBB over the ethernet link...
2014-07-29T17:41:14 < Laurenceb_> i need another ssh terminal
2014-07-29T17:41:42 < Laurenceb_> but i cant connect
2014-07-29T17:41:50 < Laurenceb_> nvm it worked
2014-07-29T17:42:39 < rewolff1> The ssh or the tenet to google?
2014-07-29T17:42:48 < Laurenceb_> the ssh
2014-07-29T17:43:01 < rewolff1> ok
2014-07-29T17:44:10 < Laurenceb_> wtf
2014-07-29T17:44:18 < Laurenceb_> HTTP/1.0 400 Bad Request
2014-07-29T17:44:22 < rewolff1> :-)
2014-07-29T17:44:37 < rewolff1> You didn't speak HTTP?
2014-07-29T17:44:46 < rewolff1> :-)
2014-07-29T17:44:46 < Laurenceb_> it took ages
2014-07-29T17:45:06 < Laurenceb_> oh maybe it was connected
2014-07-29T17:45:16 < Laurenceb_> ah yes
2014-07-29T17:45:24 < Laurenceb_> different telnet client on the BBB
2014-07-29T17:45:32 < Laurenceb_> i thought it was timing out lol

2014-07-29T17:45:47 < Laurenceb_> just need DNS now, thanks

2014-07-29T17:46:03 < rewolff1> in /etc/resolv.conf
2014-07-29T17:46:12 < rewolff1> The IP address is my server here that you won't be able to contact. :-)
2014-07-29T17:46:15 < rewolff1> try 8.8.8.8
2014-07-29T17:46:26 < Laurenceb_> its already 8.8.8.8
2014-07-29T17:46:34 < rewolff1> Hmm.
2014-07-29T17:46:43 < rewolff1> Let me think.
2014-07-29T17:47:08 < rewolff1> host www.bitwizard.nl 8.8.8.8
2014-07-29T17:47:17 < rewolff1> On your Linux box? On the BBB ?
2014-07-29T17:47:31 < Laurenceb_> on the BBB
2014-07-29T17:47:51 < rewolff1> Let me expand on that....
2014-07-29T17:48:18 < rewolff1> What do you get as output if you type " host www.bitwizard.nl 8.8.8.8 " on your Linux box? And what do you get if you do that on the BBB ?
2014-07-29T17:48:53 < rewolff1> You might have a NAZI network admin
2014-07-29T17:49:04 < rewolff1> (if he blocks ping, that's a hint).
2014-07-29T17:49:17 < rewolff1> so he might be enforcing that you use HIS DNS server....
2014-07-29T17:49:47 < rewolff1> So, how about copying the "nameserver" line from you Linux box to the BBB ?
2014-07-29T17:49:48 < Laurenceb_> nothing on linux box
2014-07-29T17:49:54 < Laurenceb_> ;; connection timed out; no servers could be reached
2014-07-29T17:49:54 < rewolff1> Hmm. Hint!
2014-07-29T17:50:05 < Laurenceb_> oh i think there is a DNS server
2014-07-29T17:50:15 < Laurenceb_> just a sec, i will find network admin
2014-07-29T17:50:22 < rewolff1> Nah!
2014-07-29T17:50:28 < rewolff1> just look in /etc/resolv.conf
2014-07-29T17:50:32 < rewolff1> on your Linux box.
2014-07-29T17:50:43 < rewolff1> You have a working nameserver listed there.
2014-07-29T17:53:16 < Laurenceb_> ok

2014-07-30T00:46:57 < ds2> emeb: nice job on the rx
2014-07-30T00:47:17 < emeb> ds2: aha - you got a look at the hfrx project?
2014-07-30T00:50:57 < Laurenceb__> sup trolls
2014-07-30T00:51:00 < Laurenceb__> BBB is fail
2014-07-30T00:51:06 < emeb> lol
2014-07-30T00:51:12 < emeb> what's you're complaint?
2014-07-30T00:51:14 < Laurenceb__> now i have to stick a jumper to MUX_OUT
2014-07-30T00:51:20 < Laurenceb__> from R163

2014-07-30T00:51:46 < emeb> have you considered rpi?
2014-07-30T00:51:57 < emeb> I hear it's the latest thing
2014-07-30T00:52:16 < Laurenceb__> lol
2014-07-30T00:52:19 < Steffanx> and you have to do that because....
2014-07-30T00:52:24 < Laurenceb__> its more fail than BBB
2014-07-30T00:52:41 < Laurenceb__> Steffanx: to monitor battery voltage from the PMIC
2014-07-30T00:53:57 < Steffanx> just drill a hole in the pcb.
2014-07-30T00:54:09 < ds2> emeb: briefly... buried with stuff at the moment
2014-07-30T00:54:24 < Laurenceb__> lol
2014-07-30T00:54:25 < ds2> Laurenceb_:just add a single SOT-23 and be done with
2014-07-30T00:54:35 < Laurenceb__> well there are gerbers available
2014-07-30T00:54:51 < ds2> the INA219 can do it
2014-07-30T00:55:01 < emeb> ds2: the hfrx needs some stuff out front - a lowpass filter and switchable attenuation.
2014-07-30T00:55:01 < ds2> pop it on the I2C bus and call it a day
2014-07-30T00:55:25 < Steffanx> what kind of equipment do you have in front of it emeb?
2014-07-30T00:55:26 < ds2> emeb: lowpass? what's overloading it? or is that image rejection stuff?
2014-07-30T00:56:12 < Steffanx> or all custom stuff
2014-07-30T00:56:38 < emeb> ds2: the QSD is sensitive to odd harmonics of the LO
2014-07-30T00:57:02 < emeb> so need to lowpass filter the input RF > 2xLO
2014-07-30T00:57:38 < emeb> attenuation is mainly needed if you listen to local AM - very strong, overloads it.
2014-07-30T00:57:51 < emeb> not a problem when you're not tuned to the strong signal tho.

2014-07-30T01:00:56 < emeb> so, planning a tunable lowpass & front-end AGC. the next project after I get some other stuff out of the way.
2014-07-30T01:01:13 < emeb> ds2: Tesla's power broadcast!
2014-07-30T01:01:32 < ds2> that stuff was all over the older books
2014-07-30T01:01:43 < ds2> guessing 60's era from what I recall of the books/fonts
2014-07-30T01:01:44 < emeb> yeah - I've seen some of it.
2014-07-30T01:02:33 < Laurenceb__> i dont get the obsession with Tesla
2014-07-30T01:02:46 < Laurenceb__> he was a loon and 90% of his stuff was unworkable
2014-07-30T01:03:16 < emeb> but the 10% that was workable was better than most other people's 100%

2014-07-30T01:05:23 < Laurenceb__> if his successful stuff was just random chance
2014-07-30T01:05:46 < Laurenceb__> steampunk arduino user...
2014-07-30T01:05:50 < emeb> my explanation: "I want to believe" he made outrageous claims and was successful often enough that nut-jobs latched on.
2014-07-30T01:10:22 < emeb> Laurenceb__: what good does it do to wire from R163 to MUXIN on the PMIC?
2014-07-30T01:11:28 < ds2> it hooks up the PMIC to battery monitoring
2014-07-30T01:11:35 < Laurenceb__> mux_out not in
2014-07-30T01:11:46 < Laurenceb__> allows battery voltage monitoring and current counting
2014-07-30T01:12:06 < Laurenceb__> theres kernel support for battery monitoing tools and stuff too
2014-07-30T01:12:13 < Laurenceb__> via the BBB PMIC
2014-07-30T01:12:27 < ds2> if you do it, i'd be curious how well that works
2014-07-30T01:12:35 < ds2> I am ready to toss in a INA219 to do exactly that
2014-07-30T01:13:02 < Laurenceb__> ill try tomorrow - board is at work
2014-07-30T01:13:30 < Laurenceb__> going to put enamled copper wire through the temp sense mount hole to the PMIC

2014-07-30T03:26:28 < dongs> Crowdsourced Parts Libraries: We will eventually aim to have a very conclusive library of parts for common EDA tools like EAGLE, KiCad, and Altium.  By crowdourcing the library parts out, and using a ranking and verification system to ensure their completeness and accuracy, the burden to the designer will be reduced tremendously.  This is a huge undertaking, but if our project reaches critical mass, it becomes within reach.
2014-07-30T03:27:35 < ds2> Altium?

2014-07-30T03:31:51 < dongs> maybe they got tired of people pirating it
2014-07-30T03:31:59 < dongs> shitty MAKE:Rs
2014-07-30T03:32:04 < gxti> iirc the main feature of eagle 7 is xml, because xml is the future
2014-07-30T03:32:10 < ds2> flexlm crap can be pirated jsut as easily
2014-07-30T03:32:14 < ds2> gxti: that's eagle 6
2014-07-30T03:32:17 < gxti> oic
2014-07-30T03:32:20 < gxti> well, it's still the future.
2014-07-30T03:32:31 < ds2> eagle7 screws over legit users
2014-07-30T03:32:38 < dongs> how so
2014-07-30T03:32:40 < gxti> that's how you know they care <3
2014-07-30T03:32:58 < dongs> if youre a legit user, 'm pretty sure their license agreement said one install per machine
2014-07-30T03:33:02 < dongs> which won't affect anyone wiht flxlm
2014-07-30T03:45:25 < dongs> my technet subscription has expired :(
2014-07-30T03:45:33 < dongs> fuck microsoft for killing it
2014-07-30T03:55:38 < dongs> http://i.imgur.com/BP67pmS.png Paramount Pictures deleted this Teenage Mutant Ninja Turtles promo poster tweet featuring exploding skyscraper and a 9/11 release date
2014-07-30T03:56:05 < ds2> it wasn't tied to per machine
2014-07-30T03:56:09 < ds2> it was tied to per person
2014-07-30T03:56:38 < dongs> was it?
2014-07-30T03:56:43 < dongs> then flexlm will adress this, no?
2014-07-30T03:57:14 < ds2> no
2014-07-30T03:57:23 < ds2> flexlm requires calling them to "move" the stuff
2014-07-30T03:57:35 < ds2> they have a cap of 5 installs or something like that
2014-07-30T03:57:39 < ds2> much more restrictive then before
2014-07-30T03:57:45 < dongs> pretty sure if its jsut tied to say HDD serial# you just do that on all machines and done
2014-07-30T03:58:01 < dongs> thats what i do for shit im too lazy to relicense
2014-07-30T03:58:09 < dongs> change hdd serial number
2014-07-30T03:58:27 < ds2> that is easy enough to fake out that it won'
2014-07-30T03:58:33 < ds2> t help with preventing theif
2014-07-30T03:58:37 < ds2> but just annoys legit users
2014-07-30T03:58:47 < ds2> hence...enough of eagle
2014-07-30T03:59:10 < ds2> for around $2K, there is a orcad/allegro light setup
2014-07-30T03:59:21 < ds2> altium is $4-9K
2014-07-30T03:59:22 < dongs> what did eagle 7 introduce that MAKE:R faggots must have it?
2014-07-30T03:59:28 < dongs> nothing right?
2014-07-30T03:59:30 < ds2> nothing :D
2014-07-30T03:59:30 < dongs> its still shit
2014-07-30T03:59:32 < dongs> right.
2014-07-30T03:59:41 < ds2> eagle 6 works well enough
2014-07-30T04:00:02 < ds2> i don't do enough hw cad work to justify bigger packages...
2014-07-30T04:00:08 < ds2> for bigger stuff, I just pay a cad guy :D
2014-07-30T04:03:18 < dongs> ds2: diud you see those dickstarter dicks melting connectors
2014-07-30T04:04:29 < ds2> nope
2014-07-30T04:04:50 < dongs> During testing however we found an unacceptably high proportion of units that had issues. We quickly diagnosed the source of these issues - the connector that joins our PCB to the LCD panel. This means we are having discussions with both the manufacture the connector and our assembly house to see why these parts are failing and what we can do about it.

2014-07-30T04:12:04 < dongs> and it was shit
2014-07-30T04:12:28 < ds2> where would you go for a cheap (but slow turn) 4L board?
2014-07-30T04:12:36 < ds2> besides OSHpark
2014-07-30T04:12:43 < dongs> doesnt shitstudio do 4L now?
2014-07-30T04:12:47 < dongs> wiht like 8./8 rules lol
2014-07-30T04:12:51 < ds2> isn't that china?
2014-07-30T04:12:59 < dongs> yes,m but you said cheap
2014-07-30T04:13:07 < ds2> non china
2014-07-30T04:13:18 < dongs> lemme ask waht this american guy uses
2014-07-30T04:13:34 < ds2> i have heard they resize your gerbers w/o notifying you
2014-07-30T04:13:39 < dongs> yes they do
2014-07-30T04:13:42 < dongs> lulz
2014-07-30T04:13:44 < dongs> ourpcb too
2014-07-30T04:13:52 < dongs> they enlarge silk or any other shit they think neesd enlarging
2014-07-30T04:14:25 < dongs> oh wtf
2014-07-30T04:14:26 < ds2> i rather have them reject the order or put a cad hold then just resize shit
2014-07-30T04:14:28 < dongs> he used hackvana shit
2014-07-30T04:14:30 < dongs> for 6L board
2014-07-30T04:14:32 < dongs> "quality is awesome"
2014-07-30T04:15:07 < dongs> hackvana = chinese crap
2014-07-30T04:15:09 < ds2> isn't 6L still pretty expensive in 100-200 quantities?

2014-07-30T04:19:59 < ds2> *shrug*
2014-07-30T04:20:52 < ds2> $520 for 11 isn't bad... paid more elsewhere for 4L stuff before
2014-07-30T04:20:56 < ds2> but quicker turn
2014-07-30T04:22:42 < dongs> yea, I think my place 4L is around 400ish for prototypes
2014-07-30T04:23:51 < ds2> but for small runs ($100-$200), I don't think the PCB costs will drop below $5 for 6L stuff
2014-07-30T04:23:57 < dongs> nope
2014-07-30T04:24:03 < ds2> 100-200 pcs I mean
2014-07-30T04:24:04 < dongs> <kevtris> board incremental cost was something like $6-7 I think
2014-07-30T04:24:07 < dongs> ^  for his prpotos
2014-07-30T04:24:15 < dongs> so most of that shit was setup

2014-07-30T05:49:50 < upgrdman> regarding floating point numbers, i normally thing of single/double as 32/64bits. it that always the case, or does single==word size? so, if for some stupid reason an 8bit mcu has hw float, single would be 1 byte?
2014-07-30T05:50:05 < dongs> no
2014-07-30T05:50:14 < dongs> and floats on avrtard are always double
2014-07-30T05:50:18 < dongs> even if you call it 'float'
2014-07-30T05:50:32 < dongs> on arm, float = 32bit, double = 64? or 48 or wahtever
2014-07-30T05:51:14 < upgrdman> so "single" and double" are always architecture defined, and need not match word size or some other metric?
2014-07-30T05:51:43 < dongs> what is "single"? single is some BASIC shit.
2014-07-30T05:51:53 < dongs> there's float and double in C.?
2014-07-30T05:51:56 < upgrdman> ok well, not-double
2014-07-30T05:52:06 < upgrdman> language agnostically
2014-07-30T05:52:15 < dongs> IEEE754 or wahtever  floats, single = 32bit, double =64bit
2014-07-30T05:52:41 < dongs> i duno if its platform specific, more like compiler specific?
2014-07-30T05:52:49 < dongs> i.e. gcc for avrturd floats=double=64bit
2014-07-30T05:53:05 < upgrdman> if hw, how would it be compiler-specific? is it not just op codes?
2014-07-30T05:53:19 < dongs> well, avr doesnt have hardware float.

2014-07-30T06:47:00 < dongs> (spending weeks figuring out how to make it work)
2014-07-30T06:48:22 < dongs> i should make a plugin for eclipse, call it ARM INTEGRATED DEVELOPMENT SYSTEM (AIDS) and all it does is opens a terminal window with gdb.exe
2014-07-30T06:48:46 < jadew> I don't care about the debugger really
2014-07-30T06:48:57 < jadew> I just want proper code completion
2014-07-30T06:49:21 < jadew> being new to STM32 it would help a lot (and probably later as well)
2014-07-30T06:50:05 < dongs> so why not just use eclipse ?
2014-07-30T06:50:09 < dongs> and build on command line or something
2014-07-30T06:50:54 < jadew> I don't know... it's always been a painful experience

2014-07-30T07:17:02 < jadew> I got the trial and testing it right now
2014-07-30T07:18:36 < upgrdman> trial? they're free
2014-07-30T07:19:03 < jadew> yeah, but I don't mind paying for it if it's nice

2014-07-30T07:33:07 < jadew> something I notice is that the stdperiph library is different
2014-07-30T07:34:21 < jadew> the one that VisualGDB installed says it's version 1.1.0 and last modified this year in June, while the one I got from ST says is 1.3.0, but modified in 2013
2014-07-30T07:34:35 < dongs> laff
2014-07-30T07:34:37 < dongs> is this for f4?
2014-07-30T07:34:41 < jadew> yeah
2014-07-30T07:35:23 < jadew> the function names are completely different too
2014-07-30T07:35:39 < jadew> for example the "How to use this driver" on 1.1.0 says __CAN1_CLK_ENABLE()
2014-07-30T07:35:50 < jadew> on 1.3.0 says RCC_APB1PeriphClockCmd
2014-07-30T07:35:57 < jadew> which one is more current?
2014-07-30T07:36:09 < jadew> personally I like the first one, it's clean and doesn't hurt my eyes
2014-07-30T07:36:42 < jadew> well, on 1.3.0 says RCC_APB1PeriphClockCmd(RCC_APB1Periph_CAN1, ENABLE); to be precise
2014-07-30T07:36:56 < jadew> any idea what's going on there?

2014-07-30T09:35:50 < jadew> PaulFertser, I can debug fine with out having to step through the code too

2014-07-30T09:39:30 < dongs> (4layer)
2014-07-30T09:41:45 < PaulFertser> jadew: for tracing memory corruption issues when using RTOS watchpoints are indespensable, it's also usually faster to just stop your real hardware at some specific place to see the variable values than adding debugging printfs and reflashing.
2014-07-30T09:41:59 < dongs> definitelye
2014-07-30T09:42:05 < dongs> printf debugging is fucktarded
2014-07-30T09:42:07 < dongs> on many levels
2014-07-30T09:44:00 < jadew> PaulFertser, obviously, but I'm not feeling any kind of need for a debugger
2014-07-30T09:44:09 < jadew> if it's there, fine, if not, I can deal without it

2014-07-31T01:05:31 < johntramp> this is flashing via openocd
2014-07-31T01:06:07 < johntramp> the verify fails,  but if I flash using st-flash then the openocd verify succeeds
2014-07-31T01:08:10 < johntramp> do I need to tell openocd to erase first?
2014-07-31T01:13:23 < johntramp> ah just found the program command,   much easier :)

2014-07-31T04:10:27 < upgrdman> if i power my mcu via usb, and if my laptop is plugged into wall power, when i clip the ground lead of my scope probe to the ground plane of my mcu breakout board the mcu will sometimes reset. but only if my laptop has wall power. if not, the mcu works perfectly. the laptop power supply has only two prongs, so i would assume it's isolated. any idea why this happens?
2014-07-31T04:10:34 < upgrdman> video of it happening is here: https://www.youtube.com/watch?v=WNrfEpMfjqg
2014-07-31T04:13:56 < GargantuaSauce> either the laptop ps is not isolated (- rail connected to ground) and you're getting a ground loop through the laptop
2014-07-31T04:15:00 < GargantuaSauce> okay you just mentioned it probably is isolated (yeah apple adapter has 2 pins)
2014-07-31T04:16:01 < GargantuaSauce> in which case there's probably enough capacitive coupling through its transformer to mains that the laptop ground is buzzing with at least a few volts wrt mains ground
2014-07-31T04:16:26 < GargantuaSauce> which obviously you'll be able to see if you leave the scope ground clip floating and probe the ground of your mcu
2014-07-31T04:17:51 < GargantuaSauce> also other peripherals connected to the laptop can be a factor
2014-07-31T04:18:04 < GargantuaSauce> i've accidentally sunk a couple A through my laptop's usb ground into an hdmi-connected monitor
2014-07-31T04:18:11 < GargantuaSauce> it didn't like that very much
2014-07-31T04:19:31 < jadew> is there any chip from the stm32 family that can work as a synchronous slave with USART?
2014-07-31T04:23:24 < GargantuaSauce> upgrdman: so what i would recommend doing is first check if your usb ground will actually sink more than a couple mA to mains earth, ie connect it to the scope ground through a resistor and measure the voltage across it with the probe
2014-07-31T04:23:52 < GargantuaSauce> and if it doesn't, use a non-isolated power supply with a usb hub
2014-07-31T04:23:55 < GargantuaSauce> i use an atx ps
2014-07-31T04:25:06 < GargantuaSauce> if it does, be very careful, and it's surprising that stuff hasn't gotten fried already. could isolate the scope i guess
2014-07-31T04:25:38 < upgrdman> k

2014-07-31T05:02:41 < jadew> dongs, that only works as a master
2014-07-31T05:03:10 < jadew> makes it pretty much useless if you plan to connect two stm32s together with it
2014-07-31T05:03:28 < dongs> oh hm. USART_CK is output only he?
2014-07-31T05:03:35 < jadew> yep
2014-07-31T05:05:28 < jadew> kinda hard to bitbang UART at up to 10 Mbps while maintaining a USB connection
2014-07-31T05:05:53 < jadew> you get only 16 cycles to do it
2014-07-31T05:05:56 < dongs> why bitband?
2014-07-31T05:05:58 < dongs> thats what DMA is for
2014-07-31T05:06:01 < dongs> er bang
2014-07-31T05:06:14 < jadew> dongs, because I need it to act as a slave
2014-07-31T05:06:27 < dongs> yes. so whats wrong wiht DMA receive?
2014-07-31T05:06:36 < jadew> can DMA do all that?
2014-07-31T05:06:42 < dongs> why not?
2014-07-31T05:06:45 < dongs> what is "all that"?
2014-07-31T05:06:55 < jadew> because the peripheral itself can't be driven from an external clock
2014-07-31T05:07:24 < dongs> yes but if your baud rate is known you just set it and it'll sync
2014-07-31T05:07:43 < jadew> well, then I wouldn't need synchronous UART :P
2014-07-31T05:07:56 < dongs> indeed, so why do you think you need one?
2014-07-31T05:08:16 < jadew> I need it because the two chips won't run at the same frequencies
2014-07-31T05:08:26 < dongs> ???
2014-07-31T05:08:27 < jadew> and one of them will run on a varrying frequency
2014-07-31T05:08:51 < dongs> what makes you think running it at different frequency isnt gonna affect sync uart
2014-07-31T05:08:58 < dongs> its clocked off APB or whatever just same
2014-07-31T05:09:24 < jadew> because sampling is done on the generate UART clock
2014-07-31T05:09:29 < jadew> *generated
2014-07-31T05:09:37 < dongs> ok. so why not just use SPI and call it done?
2014-07-31T05:10:04 < jadew> because the other chip won't know the frequency
2014-07-31T05:10:15 < jadew> so it might start sending data at a higher rate

2014-07-31T05:11:44 < dongs> wait wat
2014-07-31T05:11:50 < dongs> master will always clock spi
2014-07-31T05:12:05 < dongs> so evne when slave replying, its still master clocking it
2014-07-31T05:12:07 < jadew> yes, but in order to get UART like communication over SPI
2014-07-31T05:12:12 < jadew> you need 2 SPI peripherals
2014-07-31T05:12:16 < jadew> one master on each side
2014-07-31T05:12:36 < dongs> you need fullduplex or something>?
2014-07-31T05:12:40 < jadew> yep
2014-07-31T05:13:01 < dongs> can you clock slave off uart_ck?

2014-07-31T05:13:19 < jadew> nope
2014-07-31T05:13:28 < dongs> ok then youre ufcked
2014-07-31T05:13:31 < jadew> thought about that too :)
2014-07-31T05:13:35 < jadew> yeah... I figured
2014-07-31T05:15:58 < jadew> I'm slowly bending towards using an FPGA and be done with this madness, it's super hard to find a chip that does everything you need
2014-07-31T05:17:04 < jadew> but I'm trying to save cost so...

2014-07-31T08:08:41 < dongs> ya i had f3 run stable @ 128m
2014-07-31T08:08:45 < upgrdman> 48 -> 64MHz for my f0
2014-07-31T08:09:00 < upgrdman> may try harder if it's stays stable at 64
2014-07-31T08:09:41 < upgrdman> what's the f3 rated for?
2014-07-31T08:09:51 < dongs> 72
2014-07-31T08:10:42 < upgrdman> did you try past 128? what happened? hardfaults? silent errors?
2014-07-31T08:11:00 < dongs> F1?
2014-07-31T08:11:11 < dongs> no i think some peripheral broke and i didnt bother past that
2014-07-31T08:11:11 < upgrdman> ? me? f0 for now
2014-07-31T08:11:24 < upgrdman> permanently broke?
2014-07-31T08:11:25 < dongs> i think max i can do with 12mhz xtal is 144
2014-07-31T08:11:28 < dongs> no haha
2014-07-31T08:11:32 < upgrdman> ok good
2014-07-31T08:11:42 < upgrdman> im not evening dicking with an xtal. just HSI
2014-07-31T08:11:42 < dongs> probably it would work i'd just have to reclock APB maybe or something
2014-07-31T08:24:07 < dongs> upgrdman: F1 cant HSI that high
2014-07-31T08:24:11 < dongs> its /2'd to start with
2014-07-31T08:24:14 < dongs> so max y ou can do is 64
2014-07-31T08:24:17 < dongs> with prescaler12 or whatever
2014-07-31T08:24:27 < dongs> but with HSE, and higher freq xtal, its possible to go quite a bit

2014-07-31T21:11:18 < Laurenceb_> if that patch hasnt been buit in there is no point trying
2014-07-31T21:11:45 < Sync> it probably has
2014-07-31T21:12:23 < Laurenceb_> its not in latest angstrom

2014-07-31T21:13:45 < Laurenceb_> so i doubt its in debian
2014-07-31T21:13:59 < Sync> that's because the latest ansgtröm is pretty old
2014-07-31T21:15:32 < Abhishek__> Laurenceb_: it's very likely the BBB is using a 3.8 kernel and that patch has already made into the kernel
2014-07-31T21:15:56 < Abhishek__> so just download the image, xzcat it into your microSD card and boot it
2014-07-31T21:16:24 < Sync> hmm, 3.8, that's also pretty old
2014-07-31T21:17:22 < Laurenceb_> im running 3.8 already
2014-07-31T21:17:27 < Abhishek__> yup, it is, but it's the only one that has full cape support. The BBB can run off latest upstream kernels but some parts of the HW may or may not work
2014-07-31T21:17:31 < Laurenceb_> but its using 40mA on shutdown
2014-07-31T21:17:48 < Abhishek__> did you hit the reset button?
2014-07-31T21:18:02 < Laurenceb_> yes
2014-07-31T21:18:03 < Laurenceb_> no
2014-07-31T21:18:08 < Laurenceb_> i hit the power button
2014-07-31T21:18:17 < Laurenceb_> when power is first applied its using <1mA
2014-07-31T21:18:24 < Laurenceb_> then it goes to 210mA running
2014-07-31T21:18:29 < Laurenceb_> on shutdown its 40mA
2014-07-31T21:18:41 < Laurenceb_> i need <1mA, as its going to be battery powered
2014-07-31T21:19:00 < Abhishek__> I see, might want to try a newer kernel then
2014-07-31T21:19:18 < Laurenceb_> im running the latest
2014-07-31T21:20:12 < Abhishek__> er, the latest is 3.16 or something IIRC
2014-07-31T21:20:24 < Laurenceb_> oh
2014-07-31T21:20:30 < Laurenceb_> maybe something is wrong when i update
2014-07-31T21:21:27 < Laurenceb_> Linux version 3.8.13 (koen@rrMBP) (gcc version 4.7.3 20130205 (prerelease) (Linaro GCC 4.7-2013.02-01) ) #1 SMP Thu Sep 12 10:27:06 CEST 2013
2014-07-31T21:21:31 < Abhishek__> get the latest system image and the kernel. You should be fine
2014-07-31T21:22:40 < Abhishek__> You might be able to get help on #beagle
2014-07-31T21:22:50 < Laurenceb_> theres nobody active in there
2014-07-31T21:22:59 < Laurenceb_> whats the angstrom package manager called?
2014-07-31T21:23:45 < zyp> rm
2014-07-31T21:23:48 < Laurenceb_> lol
2014-07-31T21:24:02 < Laurenceb_> nvm its opkg
2014-07-31T21:26:34 < Laurenceb_> opkg thinks its the latest version
2014-07-31T21:27:23 < Abhishek__> yep, it might be
2014-07-31T21:28:35 < Laurenceb_> but this is newer
2014-07-31T21:28:36 < Laurenceb_> http://beagleboard.org/latest-images
2014-07-31T21:30:48 < bvernoux> anyone know when the new BBB will be available ?
2014-07-31T21:30:59 < bvernoux> with latest TI chipset CortexA9 and lot of coprocessor
2014-07-31T21:31:34 < Laurenceb_> and maybe working PMIC
2014-07-31T21:32:00 < bvernoux> there is 4 PRU ;)
2014-07-31T21:32:09 < bvernoux> in latest AM437x
2014-07-31T21:33:36 < Laurenceb_> yes but will power management be fixed...
2014-07-31T21:33:39 < Laurenceb_> im guessing not

2014-07-31T22:05:38 < scrts> Laurenceb_: and what's wrong with it?
2014-07-31T22:05:50 < scrts> the more I deal with TI, the more shit comes up...
2014-07-31T22:05:52 < Laurenceb_> it doesnt shut down
2014-07-31T22:06:12 < Laurenceb_> ok downloaded latest debian
2014-07-31T22:06:15 < Laurenceb_> how do i flash it?
2014-07-31T22:06:17 < scrts> when you halt the system?
2014-07-31T22:06:30 < Laurenceb_> when i shutdown
2014-07-31T22:06:42 < Laurenceb_> its still drawing 40mA
2014-07-31T22:07:10 < scrts> probably it's a smartass having internal logic stuff
2014-07-31T22:07:25 < scrts> like LDO, which is constantly working
2014-07-31T22:07:30 < scrts> dunno honestly
2014-07-31T22:09:06 < Laurenceb_> any idea how to load a new image to eMMC?
