2013-10-01T03:29:38 < markiv> hello, i am trying some simple program tests (led blinking) to check freertos on my stm32f103CB chip using IAR. i have a couple of questions, can anyone with some freertos experience help? thanks
2013-10-01T03:31:47 < dongs> IAR, freertos? you couldnt have picked worse combo of stuff.
2013-10-01T03:31:57 < markiv> is it?
2013-10-01T03:32:12 < dongs> i'd say so

2013-10-01T03:32:30 < dongs> keil > IAR by far, and feertos............ i'd probably even pick chibios over that shit.
2013-10-01T03:32:31 < markiv> what would you suggest?
2013-10-01T03:32:40 < markiv> ok
2013-10-01T03:32:48 < dongs> tho my personal favorite is coos. whats hte problem anyway?
2013-10-01T03:32:50 < dongs> blinking led isnt hard
2013-10-01T03:32:59 < dongs> does feertos have a hal? or you just use stdperiphlib?
2013-10-01T03:33:15 < dongs> i dont think it does, so you just configure gpio based on ST exampls and go?
2013-10-01T03:33:30 < markiv> i have setup led to blink every 1 second, but for some reason it is blinking every 9 seconds
2013-10-01T03:33:43 < dongs> sounds like you fucked up clock config
2013-10-01T03:33:49 < markiv> i'm using a freertos demo for iar
2013-10-01T03:33:50 < dongs> what evalboard are you using?
2013-10-01T03:33:59 < dongs> and whats the crystal on it
2013-10-01T03:34:08 < markiv> all the clock config seems fine for example the portTICK, TICKRATE_HZ etc
2013-10-01T03:34:19 < dongs> right, im talking about actual hardware PLL setup
2013-10-01T03:34:23 < markiv> crystal is 16 MHZ
2013-10-01T03:34:56 < dongs> not sure if you can actualyl use that on F103CB.
2013-10-01T03:35:33 < markiv> i have also tried a similar program using atollic lite
2013-10-01T03:35:41 < dongs> what's your RCC_CFGR_PLLMUL set to.
2013-10-01T03:41:07 < markiv> from the header file it says ((uint32_t)0x003C0000) though i'm not sure if that is what you were looking for..
2013-10-01T03:45:27 < markiv> i am working with a custom stm32f103cb board

2013-10-01T04:04:25 < dongs> shitty.
2013-10-01T04:04:28 < dongs> fucking magic numbers.
2013-10-01T04:04:32 < dongs> rewrite that stuff properly.
2013-10-01T04:10:16 < Thorn> markiv: default stdperiph lib config for f103 is 72MHz with a 8MHz crystal, so if you didn't change it you'd be trying to run at 144MHz
2013-10-01T04:14:24 < markiv> ok i will change that, thanks Thorn and dongs

2013-10-01T09:30:26 < emeb_mac> dongs: yep - gcc
2013-10-01T09:33:07 < PaulFertser> Found your problem, hehehe
2013-10-01T09:33:50 < emeb_mac> no problem - can't expect a raytracer running on a 72MHz ARM to run particularly fast.
2013-10-01T09:34:12 < emeb_mac> Considering it takes like 20s to run on a 2GHz Intel processor...
2013-10-01T09:34:17 < PaulFertser> But dongs can, if the raytracer is compiled with Keil
2013-10-01T09:34:29 < emeb_mac> heh
2013-10-01T09:34:51 < emeb_mac> Keil is OK - been using it for other projects for a couple of months now.

2013-10-01T09:40:41 < dongs> emeb_mac: smalelr size = less flash reads = faster
2013-10-01T09:41:00 < PaulFertser> If you have unrolled code, all the instructions are prefetched, so no penalty here. If you have tight code it needs more branching, hence more wait states for the flash. Am I missing something?
2013-10-01T09:41:32 < dongs> gcc still has a bug open for shit like foo[0] << 8 | foo[1] not turning into REV16 on arm...
2013-10-01T09:41:54 < emeb_mac> yeah - it misses a lot of obvious stuff.
2013-10-01T09:42:16 < emeb_mac> but it's great at unrolling / interleaving the DSP stuff that I do.

2013-10-01T11:36:42 < ohsix> um what was that term i made up, kickshopping? yea, a lot of people are on there basically getting things bought for them (i know, sort of the point) except it's tooling and crap that's most of the asking price of the whole thing
2013-10-01T11:39:05 < ohsix> if they were actually getting money to have the stuff manufactured it'd be much less, as you don't really have to deliver anything, they'd still have the equipment

2013-10-01T11:42:03 < jpa-> most of them don't fail on purpose.. i guess kickstarter could start organizing some support groups on how to properly plan your campaign to avoid over-optimism
2013-10-01T11:45:44 < ohsix> i guess, but failing is a great strategy
2013-10-01T11:47:17 < ohsix> i don't think it's even about optimism either
2013-10-01T11:47:47 < ohsix> just like, not even having done anything in the problem domain and having no idea, not even making some phone calls before they have their plans all set and up on kickstarter
2013-10-01T11:49:26 < jpa-> yeah.. in a way it makes sense to see if anyone is interested before investing time.. but that also means you lack the information necessary to plan it
2013-10-01T11:50:41 < ohsix> sure, but that time just has to be spent before you expect to get peoples money to follow up
2013-10-01T11:51:24 < ohsix> nobodies idea is so great that they can't just not do any of the work themselves, even if it's basic feasibility and calling around for prices
2013-10-01T11:52:26 < ohsix> it' sjust extra dishonest, but it doesn't really matter to the people giving kickstarter projects money, they've got even less exposure to the feasibility of any given thing
2013-10-01T11:52:57 < jpa-> as far as scams go, these are pretty small amounts of money anyway :)

2013-10-01T11:55:28 < ohsix> buzz can be influenced if you have cash on hand too, that funding number has its own trend, and if you are spreading it around, ugh, i just don't like it
2013-10-01T11:55:37 < Robint91> hi all
2013-10-01T11:55:58 < jpa-> hello
2013-10-01T11:57:22 < ohsix> the number being high early can easily be interpreted as popularity or some sort of merit, and when the actual buy in is as low as a dollar, it's a little self perpetuating
2013-10-01T11:59:31 < ohsix> if you had some of your own money to throw in on the deal, doing it early via kickstarter is definitely a solid thing to do
2013-10-01T11:59:51 < ohsix> it's not like you lose the money, you pay a fee but you can almost freely change the number at will
2013-10-01T12:00:38 < jpa-> hmm yeah.. perhaps a bit too fishy for most of the honest people there :)
2013-10-01T12:02:31 < ohsix> it's a cool forum for resellers too ;D fancy story about all the stuff, cross your fingers nobody finds it on dealextreme for the real price
2013-10-01T12:14:22 < zyp> http://z.svbtle.com/why-kickstarter-projects-are-always-delayed/ <- has this been discussed yet?
2013-10-01T12:21:10 < dongs> if I ever make a dickstarter, it will be early.
2013-10-01T12:22:31 < dongs> Yield (the percentage of products that come off the manufacturing line that are fully functional) is a tricky business, and factors into your costs. If 10% of your products fail on the manufacturing line, then your manufacturer has to charge you 10% extra for the functional units to cover the cost of the “scrap”.
2013-10-01T12:22:36 < dongs> thats pretty fucking terrible
2013-10-01T12:23:00 < dongs> my last 2k units production run had maybe ~8 boards that were dead on power up due to misaligned components mostly, which got fixed and then it was 100%
2013-10-01T12:23:23 < dongs> i guess if you're a tool you can somehow manage 10% failure

2013-10-01T12:24:13 < jpa-> also, with the ridiculous prices on most kickstarter stuff, i would assume a 50% margin or more.. so 10% extra cost is no reason to delay..

2013-10-01T16:57:45 < zyp> heh, really
2013-10-01T16:57:49 < jpa-> still quite nice biking weather
2013-10-01T16:58:18 <+Steffan-> emeb_mac .. can't you invite us to your house this weekend?
2013-10-01T16:58:23 < zyp> it's still 10-15 at day and 5-10 at night here
2013-10-01T16:58:26 < jpa-> have to put the winter tires on in a few weeks.. but when it gets below zero, it becomes more difficult to breath while biking
2013-10-01T16:58:33 < emeb_mac> Steffan-: sure, come on over.
2013-10-01T16:59:25 < emeb_mac> jpa-: what do winter tires have to do with breathing?
2013-10-01T16:59:28 < jpa-> zyp: so it was here also until a week ago  http://aimonen.fi/lampotila/images/month_minmax.png

2013-10-01T17:00:00 < zyp> I started wearing a jacket over my t-shirt when going outside only a week or two ago :p
2013-10-01T17:00:01 <+Steffan-> jpa-, when you'll give us a version in english?
2013-10-01T17:00:22 <+Steffan-> *make us
2013-10-01T17:00:22 < jpa-> Steffan-: i don't think the temperature at my home will interest the whole world.. :)
2013-10-01T17:00:30 <+Steffan-> of course it's interesting.
2013-10-01T17:00:40 <+Steffan-> the image name is in english :P

2013-10-01T17:02:10 < jpa-> it's pretty hard to guess what goes with min and max :)
2013-10-01T17:02:15 < emeb_mac> the little two-letter abbrevs on the x axis are cute tho - looks like "do re me fa so la ti do"
2013-10-01T17:02:23 <+Steffan-> :D
2013-10-01T17:02:50 < jpa-> emeb_mac: actually the "ma ti ke to pe la su" sequence in finnish does sound a bit like "do re mi fa" :)
2013-10-01T17:03:44 < emeb_mac> keskiarvo - average. google translate ftw, plus big surprise.
2013-10-01T17:04:08 < emeb_mac> jpa-:  is that weekday?
2013-10-01T17:04:12 < emeb_mac> or month?
2013-10-01T17:04:12 < jpa-> emeb_mac: yeah
2013-10-01T17:04:42 < jpa-> the graph is the last 30 days, the x axis abbrevs is the weekday (and the date underneath it) marked for every 3 days
2013-10-01T17:05:07 < emeb_mac> oooh - modulo and sampling.
2013-10-01T17:05:40 <+Steffan-> emeb_mac, meh.. i just tried to make jpa- useful for 10 seconds :P
2013-10-01T17:05:45 <+Steffan-> *make himself useful
2013-10-01T17:06:33 < jpa-> http://aimonen.fi/lampotila/images/daypie.png  still a few months before it gets really cold
2013-10-01T17:07:06 < emeb_mac> it's funny - as mostly english speaker I can extrapolate a lot of euro-languages. but finnish is pretty much out.
2013-10-01T17:07:12 <+Steffan-> Not even a word that looks a bit like english or dutch or..
2013-10-01T17:07:20 < jpa-> we think different :)
2013-10-01T17:07:23 < emeb_mac> not enough cross-pollination I guess
2013-10-01T17:07:32 < emeb_mac> too far north. :)
2013-10-01T17:08:22 < emeb_mac> when I first started seeing finnish I thought it was japanese.
2013-10-01T17:08:33 <+Steffan-> no japanese is worse.
2013-10-01T17:08:59 <+Steffan-> I can at least 'read' the characters the finnish use :)
2013-10-01T17:09:04 < emeb_mac> yep
2013-10-01T17:09:34 < emeb_mac> why can't those asians just use normal letters :P
2013-10-01T17:09:58 < jpa-> Steffan-: äöäåöäå
2013-10-01T17:10:21 < emeb_mac> lol - at least I can guess what those should sound like
2013-10-01T17:10:22 < jpa-> ääkköset ällistyttävät älyttömästi
2013-10-01T17:10:28 <+Steffan-> Like the word laugh. You see a symbol that looks like =) .. so you think that is 'laugh', but it turns out it's the symbol that looks like a little girl with pony tails

2013-10-01T17:11:05 <+Steffan-> Yeah.
2013-10-01T17:11:12 < jpa-> why would anyone need a symbol for that.. and do they have a symbol for "really loud shit" also?
2013-10-01T17:11:39 < emeb_mac> rofl
2013-10-01T17:11:42 < jpa-> i guess =) might be the face you make when you manage to do a soundless shit.. so maybe it makes sense
2013-10-01T17:12:05  * emeb_mac is having a hard time breathing right now
2013-10-01T17:12:12 < emeb_mac> must need winter tires
2013-10-01T17:12:16 < jpa-> :D
2013-10-01T17:12:26 <+Steffan-> but realy.. how 笑 is not girl with pony tails.. ?
2013-10-01T17:12:49 <+Steffan-> probably only proper clients show some symbol now :P
2013-10-01T17:12:50 < jpa-> to me it looks like a dude with ^^ for eyes and an unibrow
2013-10-01T17:13:48 <+Steffan-> but you are right jpa-, we don't have ä's in our language, but .. at least i can see its almost an a :)
2013-10-01T17:14:05 <+Steffan-> We do have é and è and ë etc. :)
2013-10-01T17:14:11 < emeb_mac> Steffan-:  need the character that looks like a smiley and means quiet defecation...
2013-10-01T17:14:33 <+Steffan-> uh emeb_mac?
2013-10-01T17:14:56 < jpa-> ッ  there you go
2013-10-01T17:15:20 <+Steffan-> oh, you were asking for this symbol. ( is it a symbol or character ?)
2013-10-01T17:15:33 < emeb_mac> cute - google translate says "tsu"
2013-10-01T17:15:46 < zyp> yeah, it's the sound "tsu"
2013-10-01T17:15:52 < jpa-> https://en.wiktionary.org/wiki/%E3%83%83  "a choked sound"
2013-10-01T17:16:07 < emeb_mac> so this is katakana which is syllables iirc
2013-10-01T17:16:15 < zyp> yep
2013-10-01T17:16:34 < emeb_mac> that at least starts to make sense to my western brain
2013-10-01T17:16:37 < zyp> no, wait, that's the small tsu
2013-10-01T17:16:45 < zyp> https://en.wiktionary.org/wiki/%E3%83%84 <- normal one
2013-10-01T17:16:49 < jpa-> "mommy i made a big tsu!"
2013-10-01T17:16:56 < emeb_mac> but apparently using katakana is considered low-class.
2013-10-01T17:17:07 < zyp> heh
2013-10-01T17:17:21 < zyp> used to be, perhaps
2013-10-01T17:17:21 <+Steffan-> google is low-class?!
2013-10-01T17:17:34 < zyp> nowadays katakana is used for imported words
2013-10-01T17:18:35 < emeb_mac> bushuru!
2013-10-01T17:19:07 < emeb_mac> which is apparently an imported word that means "to barf on the prime minister" or something.
2013-10-01T17:19:19 <+Steffan-> lol
2013-10-01T17:19:50 < emeb_mac> derived from when american pres. bush the elder did just that during a state visit to japan...
2013-10-01T17:20:29 < emeb_mac> and they say politics is boring.
2013-10-01T17:21:10 <+Steffan-> it is.. especially this wonderful shutdown in yankeeland.

2013-10-01T17:23:03 <+Steffan-> Whats new?
2013-10-01T17:23:39 < emeb_mac> apparently nothing.
2013-10-01T17:24:11 < emeb_mac> entropy - things can only get worse. we're all on that slippery slope to the heat-death of the universe
2013-10-01T17:24:31 < emeb_mac> any improvements you may notice are only localized anomalies.
2013-10-01T17:24:53 < emeb_mac> this ray of sunshine brought to you by...
2013-10-01T17:25:17 < jpa-> why do you say it is worse?
2013-10-01T17:25:37 < emeb_mac> jpa-: that's true - "worse" is a value judgement.
2013-10-01T17:26:03 < jpa-> i would value a heat death pretty much now because they won't turn on the heating until christmas
2013-10-01T17:27:29 < emeb_mac> time to get off my ass and ride the bike. without special tires.

2013-10-01T20:25:36 < jpa-> Steffan-: i know what i'll buy you for christmas.. http://www.alibaba.com/product-free/113701868/STIFF_SCAN_EPG.html
2013-10-01T20:27:18 < qyx_> how fast can f4 write over sdio? some real benchmarks
2013-10-01T20:28:44 < zippe> qyx_: it's limited by the card clock / card internal speed for the most part
2013-10-01T20:29:10 < jpa-> yeah, SD cards have some horribly variying write latencies
2013-10-01T20:29:10 < qyx_> i am curious if it can log 2 channels from adc at 2.4msps assuming writing to class10 sd card
2013-10-01T20:29:12 < zippe> qyx_: The memory / DMA / controller pieces are more than fast enough to keep up
2013-10-01T20:29:43 < jpa-> qyx_: most cards will have stalls of 100ms occassionally.. sometimes up to 500ms
2013-10-01T20:29:48 < jpa-> so you need a lot of RAM to buffer
2013-10-01T20:29:49 < qyx_> O_o
2013-10-01T20:29:54 < zippe> You want ~10MiB/sec sustained write into an SD card; that's going to be interesting to maintain
2013-10-01T20:30:31 < qyx_> probably i just have to try :S
2013-10-01T20:30:43 < zippe> You have the bandwidth at 4x24MHz
2013-10-01T20:30:51 < zippe> It'll come down to the specific card
2013-10-01T20:31:25 < zippe> You may find it beneficial to 'format' the FAT filesystem before you start
2013-10-01T20:31:27 < jpa-> qyx_: wire up some 8 MB of SRAM and you'll be fine
2013-10-01T20:31:50  * emeb is waiting for f42x w/ SDRAM
2013-10-01T20:32:00 < zippe> Since a better card will see that you have zeroed out the FAT and won't try to do GC on the empty parts
2013-10-01T20:32:06 < qyx_> jpa-: meh, i don't like this idea
2013-10-01T20:32:21 < jpa-> yeah.. special formatting (and perhaps using without filesystem altogether) may help
2013-10-01T20:32:27 < emeb> qyx_: what's the data?
2013-10-01T20:32:43 < zippe> jpa-: no, on an SDCard you *really* want to use FAT and write single, large files sequentially
2013-10-01T20:32:48 < jpa-> if you use fatfs with defaults, it will go and change the FAT every few sectors.. which slows down a lot
2013-10-01T20:33:02 < zippe> jpa-: They are all tuned for use in cameras
2013-10-01T20:33:21 < jpa-> zippe: yeah, but cameras don't care that much about small stalls
2013-10-01T20:33:24 < zippe> If you don't put a FAT filesystem on it, the good ones become as bad as the very stupid ones
2013-10-01T20:33:38 < zippe> jpa-: it's not that, it's that the card interprets the FAT layout
2013-10-01T20:33:59 < zippe> jpa-: so it knows where you are (probably) going to write next, and which sectors do and don't need to be GC'ed.
2013-10-01T20:34:00 < qyx_> emeb: i need to log some analog waveforms directly in the field
2013-10-01T20:34:02 < jpa-> better than a simple sequential write without filesystem?
2013-10-01T20:34:08 < jpa-> hmm, interesting
2013-10-01T20:34:11 < zippe> jpa-: often, much.
2013-10-01T20:34:17 < jpa-> i only knew they GC the FAT sectors differently
2013-10-01T20:34:44 < zippe> I'm a couple years out of date, but the Big Three were all doing it
2013-10-01T20:34:47 < jpa-> qyx_: how long recording time do you need?
2013-10-01T20:35:28 < qyx_> jpa-: minimum of about 2 min
2013-10-01T20:35:39 < qyx_> also i could lower the sampling rate a bit
2013-10-01T20:35:49 < jpa-> if it just for debugging purposes, just get a USB scope that can stream in real time
2013-10-01T20:36:02 < jpa-> *it's
2013-10-01T20:36:16 < qyx_> yep but carrying the laptop there is not an option
2013-10-01T20:36:49 < qyx_> and i need to give it to someone else who will do this for me remotely
2013-10-01T20:37:14 < jpa-> something with more ram would make life a lot easier
2013-10-01T20:37:47 < jpa-> beaglebone might work? it has quite fast ADC if i remember correctly
2013-10-01T20:37:48 < qyx_> he will connect it to device, perform some operations, disconnect.. after logging on a few devices he downloads the data, compresses it and send it to me
2013-10-01T20:38:20 < qyx_> i will try that on f4disco and see
2013-10-01T20:38:41 < jpa-> talsit can tell you about the pain with SD card latencies :)

2013-10-01T20:42:17 < emeb> that which has been seen...
2013-10-01T20:42:22 < jpa-> qyx_: and he was only writing 300kB/s or so IIRC
2013-10-01T20:46:28 < qyx_> :S
2013-10-01T20:53:42 < jpa-> but zippe is correct in that if you format carefully then maybe the card is smart enough not to GC => no lag
2013-10-01T20:54:18 < jpa-> talsit did not have that option because he needed the user to be able to freely mess with the card
2013-10-01T20:56:55 < qyx_> there will be an option to clear the logs
2013-10-01T20:57:03 < qyx_> so it can be implemented as quick format

2013-10-02T00:14:13 < zyp> almost sounds like you're having usb issues
2013-10-02T00:14:20 < zyp> have you tried it on another computer?
2013-10-02T00:15:33 < virish> yes, i did..
2013-10-02T00:16:03 < zyp> same behavior?
2013-10-02T00:16:05 < virish> i tried making changes suggested here: http://www.sonsivri.to/forum/index.php?topic=45154.0
2013-10-02T00:16:44 < virish> the behavior was the same

2013-10-02T00:24:58 < virish> just tested a second stm32f4discovery board that was detected by stlink
2013-10-02T00:25:22 < virish> got the following error messages while trying to load the original stm32f4-discovery-demonstration.hex file

2013-10-02T00:26:06 < virish> so 1 board is not detected while the other has problems while loading code, can i assume i got a bad batch?

2013-10-02T02:28:22 < Laurenceb_> then i realised i could oversample a 12bit and get 19 effective bits

2013-10-02T02:28:54 < Laurenceb_> 16bit is kind of stupid when you have such a fast 12 bit on stm32
2013-10-02T02:29:03 < qyx_> btw what about common 24bit audio adcs?
2013-10-02T02:29:17 < dongs> they're slow
2013-10-02T02:29:21 < Laurenceb_> yeah but i was hitting the shot noise limit
2013-10-02T02:29:23 < Laurenceb_> so shrug
2013-10-02T02:29:26 < qyx_> 192ksps is not too slow
2013-10-02T02:29:31 < emeb> whoa - 7 bits of added resolution - that's like 16k integration?
2013-10-02T02:29:47 < Laurenceb_> yes
2013-10-02T02:29:54 < gxti> are there hidden gotchas to using audio adc or dac for other stuff? i mean other than the stated INL and such
2013-10-02T02:30:08 < emeb> gain accuracy is usually not great
2013-10-02T02:30:31 < emeb> audio adcs /dacs are designed for relative accuracy, not absolute.
2013-10-02T02:30:39 < gxti> right.
2013-10-02T02:30:56 < qyx_> and apart of that?
2013-10-02T02:31:19 < emeb> often audio I/O parts have built-in DC blocking, so they're really only good for AC coupled signals
2013-10-02T02:31:33 < gxti> that's what i'm mainly worried about.
2013-10-02T02:32:00 < emeb> sometimes you can disable the highpass filters, sometimes not. Check the data sheets.
2013-10-02T02:32:05 < qyx_> some of them explicitly state in the datasheets that external dc blocking capacitors are needed
2013-10-02T02:32:42 < gxti> at some point i want to build up a 24bit DAC for driving voltage-controlled oscillators, absolute voltage doesn't matter but it does need to be very stable over time which pretty much rules that out
2013-10-02T02:32:42 < emeb> I'm working with an I2S audio DAC right now that has DC outputs, but can't drive much DC current so you would have to use high-impedance buffers.
2013-10-02T02:32:59 < dongs> that was another thing
2013-10-02T02:33:03 < emeb> whereas if you AC couple it then there are no strong buffering issues.
2013-10-02T02:33:03 < dongs> on my screen overlay trash
2013-10-02T02:33:10 < gxti> although maybe using it with a homebrew dual-slope converter could work
2013-10-02T02:33:11 < dongs> i was told I should use buffer/follower opamp thing
2013-10-02T02:33:18 < dongs> because stm32 adc can't deliver a lot of current
2013-10-02T02:33:56 < emeb> dongs: the stm32 DAC has built-in buffering, but it has some bandwidth issues.
2013-10-02T02:33:58 < gxti> stm32 dac has an output buffer but you have to turn it off to get rail-to-rail
2013-10-02T02:34:08 < emeb> yes, that.
2013-10-02T02:34:14 < qyx_> you were feeding dac output directly to 75ohm coax?
2013-10-02T02:34:19 < emeb> plus it causes some overshoot and lag.
2013-10-02T02:35:32 < emeb> gxti: the CS4344 I2S DAC can only source/sink 10uA DC on its outputs. If you AC couple it then it's happy with much more though.

2013-10-02T02:36:37 < gxti> i've also seen an approach that involved summing two 16bit PWM DACs, kind of a coarse/fine approach which is perfect for driving VCO
2013-10-02T02:37:11 < emeb> that can work - if you have a way to calibrate out any overlap.
2013-10-02T02:37:50 < gxti> i guess i should build a dual-slope ADC just for the learning experience

2013-10-02T02:39:46 < gxti> on a completely unrelated note, haven't done any new hardware in quite a while so i'm looking at making that isolated BMP
2013-10-02T02:40:21 < emeb> isolation on the USB side or on the SWD side?
2013-10-02T02:40:46 < gxti> swd is much simpler :p
2013-10-02T02:41:02 < emeb> except for the bi-dir on the data line
2013-10-02T02:41:14 < qyx_> any i2c isolator should work
2013-10-02T02:41:29 < gxti> just need to bring an enable line across
2013-10-02T02:41:29 < emeb> enough BW?
2013-10-02T02:41:57 < qyx_> i2c can go up to ~3mbps, so probably yes
2013-10-02T02:41:57 < emeb> so tweak the BMP firmware to output a direction line.
2013-10-02T02:42:16 < gxti> yeah reading the source now, looks like a total of 3 lines changed maybe

2013-10-02T04:01:30 < emeb> I did a project with an F100 VL part that used both DACs. Tried it with and without the buffer.
2013-10-02T04:01:58 < emeb> ended up not using the buffer because of the rail-to-rail issue and the edge ringing.
2013-10-02T04:02:25 < dongs> so, just directly to line out?
2013-10-02T04:02:33 < dongs> and no issues driving high-impedance shit?

2013-10-02T04:03:10 < emeb> No, this project needed +/-2.5V outputs, so the DAC outs went immediatedly into op-amps.
2013-10-02T04:03:26 < emeb> What kind of load are you driving?

2013-10-02T04:20:58 < dongs> i have no idea waht impedanec it is tho.
2013-10-02T04:21:08 < dongs> <typical chinese a/v transmitter impedance"
2013-10-02T04:22:00 < ohsix> 75/50ohm?

2013-10-02T04:29:53 < emeb> Audio line loads are usually > 1k ohm, if not more.
2013-10-02T04:30:20 < emeb> which stm32?
2013-10-02T04:31:10 < emeb> (some older style audio loads might go as low as 600ohm, but that's rare these days)
2013-10-02T04:34:11 < emeb> so the DAC in an F105 is rated to drive 5k with the buffer and 15k without the buffer.
2013-10-02T04:35:04 < emeb> if you want to drive a line level output you could probably squeak by with the buffer enabled, but it might have reduced drive if you hook up to a lower impedance load.

2013-10-02T04:49:13 < emeb_mac> looks like thd F3 DAC is the same as the F105 DAC - 5k w/ buffer on, 15k w/ buffer off.

2013-10-02T15:44:08 < dongs> can you execute code from sram on fsmc?
2013-10-02T15:44:17 < Thorn> check fig. 2 in rm0090
2013-10-02T15:44:32 < Thorn> dongs: you can but it's slow as hell
2013-10-02T15:44:43 < Thorn> I'd expect that it's the same with sdram
2013-10-02T15:45:15 < dongs> how the fuck does lunix run on F103 then
2013-10-02T15:45:46 < karlp> slowly
2013-10-02T15:45:56 < dongs> thought so
2013-10-02T15:46:22 < Laurenceb> inb4 "same as usual"

2013-10-02T15:47:15 < dongs> Laurenceb: i got mpu6050 calibrated and I see it drifting left/right over say half an hour period
2013-10-02T15:47:16 < Robint91> clive1 post: Observations with the board, 8 MB of SDRAM readily accessible at 0xD0000000. Does not appear to support mapping to zero (bank at 0xC0000000 would have been). Does not appear to permit code execution. Pin out would appear to support a 16 MB part. SDIO operation appears to clash with LCD.
2013-10-02T15:47:26 < dongs> i always thought gyro would only drift one way
2013-10-02T15:47:36 < Laurenceb> not if its calibrated
2013-10-02T15:47:52 < dongs> im talkin like few deg/minute drift
2013-10-02T15:47:54 < Laurenceb> how did you cal?
2013-10-02T15:48:00 < Laurenceb> nice
2013-10-02T15:48:13 < dongs> just get a bunch of readings and average/subtract from each reading
2013-10-02T15:48:19 < Laurenceb> heh
2013-10-02T15:48:41 < dongs> clive1 is some kinda hax0r
2013-10-02T15:50:07 < Robint91> dongs, enlighte me
2013-10-02T15:50:27 < dongie> just look at his post history at those shitty stm forums
2013-10-02T15:50:36 < dongie> he's liek a fucking god there.
2013-10-02T15:51:30 < Laurenceb> theres some funny posts by stmone
2013-10-02T15:51:43 < dongie> ya but that guy is paid to post
2013-10-02T15:51:51 < dongie> st forums are fucking awful tho
2013-10-02T15:51:51 < Laurenceb>  "at ST we have decided to leave all support to Clive1"
2013-10-02T15:51:56 < Laurenceb> or something like that
2013-10-02T15:51:57 < dongie> haha
2013-10-02T15:52:07 < dongie> they arent wrong
2013-10-02T15:53:32 <+Steffan-> i bet clive1 is zyp is disguise ..

2013-10-02T18:52:44 < ouah> when I do an erase chip with ST-Link utility, all  flash is set to 0x00
2013-10-02T18:52:55 < ouah> I would expect it is set to 0xFF, no?
2013-10-02T18:53:02 < ouah> qyx_: yes
2013-10-02T18:53:06 < qyx_> me too
2013-10-02T18:53:29 < ouah> qyx_: old work btw
2013-10-02T18:53:35 < qyx_> still nice
2013-10-02T18:54:34 < ouah> does stm32l1xxx have some special flash technology with 0x00 values when erased?
2013-10-02T18:55:25 < Thorn> no, blank chips contain 0xff everywhere
2013-10-02T18:57:16 < ouah> ST-Link displays all bytes to 0x00 after chip erase, and if I request a blank check, it says flash memory is blank

2013-10-02T18:59:21 < zyp> L1 is actually 0x00 when blank, not 0xff
2013-10-02T18:59:23 < Thorn> stupid question: are you sure you're viewing flash?
2013-10-02T18:59:37 < Thorn> hm interesting, why would that be
2013-10-02T18:59:45 < zyp> dunno, but it is
2013-10-02T19:00:11 < Thorn> is it also 0x00 when fresh from the tray?
2013-10-02T19:00:14 < zyp> I remember also being puzzled by that when I wrote the BMP flash loading routine for L1
2013-10-02T19:00:18 < zyp> should be
2013-10-02T19:00:26 < Thorn> strange
2013-10-02T19:00:46 < zyp> well, it just means that the data lines are for some reason inverted
2013-10-02T19:01:32 < ouah> is there some documentation that explains this?
2013-10-02T19:01:48 < zyp> of course
2013-10-02T19:01:56 < ouah> zyp: any link?:)

2013-10-02T19:07:11 < karlp> oocd had a bug for a while too with blank L1s,
2013-10-02T19:07:13 < karlp> it's fixed now...
2013-10-02T19:07:58 < jpa-> yeah, it worked fine for me
2013-10-02T19:08:09 < jpa-> do i get to thank you for that? :)
2013-10-02T19:08:54 < karlp> fuck no, paulfertser maybe,
2013-10-02T19:09:47 < PaulFertser> karlp: nope, not me, someone else noticed that and Spencer fixed (adding configurable padding value field in the flash driver struct).
2013-10-02T19:10:46 < ouah> zyp: do you find something?:p
2013-10-02T19:11:20 < zyp> apparently not
2013-10-02T19:11:37 < PaulFertser> ouah: the stlink's retarded library uses 0 as the erase value for L series, no doubt about it.
2013-10-02T19:11:38 < zyp> I believe the PM had a note about it, but I'm looking through it and can't find it
2013-10-02T19:11:54 < zyp> but I can say for certain that it's 0 when erased ;)
2013-10-02T19:15:12 < ouah> PaulFertser: in this case, how can you program the flash when erasing with 0x00?
2013-10-02T19:15:23 < karlp> get a better tool
2013-10-02T19:15:30 < jpa-> st probably just shopped around for a low-power flash IP block and happened to get one with inverted data :)
2013-10-02T19:15:41 < PaulFertser> ouah: what do you mean? OpenOCD programs the parts fine
2013-10-02T19:15:49 < ouah> how can ST-Link program the flash correctly if it uses 0x00 to erase it
2013-10-02T19:15:50 < karlp> new enough openocd, or new enough st-link/stutil from st
2013-10-02T19:16:03 < zyp> looks like the flash has ECC, so that might be the reason
2013-10-02T19:16:10 < PaulFertser> Even old openocd would work as well. Padding value doesn't really matter imho.

2013-10-02T19:16:15 < karlp> if texane/stlink fails with factory blank L1s, stop using texane/stlink
2013-10-02T19:16:18 < jpa-> ouah: it's really 0xFF internally
2013-10-02T19:16:57 < ouah> jpa-: PaulFertser seems to say something different, no?
2013-10-02T19:17:28 < jpa-> ouah: PaulFertser is saying that "yes, it can be programmed".. i'm trying to say "yes, of course it can be programmed" :)
2013-10-02T19:18:01 < PaulFertser> ouah: I mean for flashing old openocd version would work too because it flashes correctly. It's just that it pads sections with 0xff, but what does it affect for you?

2013-10-02T19:21:02 < ouah> ok
2013-10-02T19:21:05 < zyp> hmm, didn't find it in the PM

2013-10-02T19:21:19 < trepidaciousMBR> Should the erase value matter? When I've done flashing on F4 I just erase enough sectors, then write the words I care about... I guess the words I don't write will have some erase value, but it doesn't really matter?
2013-10-02T19:21:22 < ouah> so ST_Link is correct when it displays 0x00
2013-10-02T19:21:48 < ouah> trepidaciousMBR: as it is the first time I see that, yes it matters for me:)
2013-10-02T19:21:52 < zyp> so I blame karlp for me believing it was mentioned in the PM :p

2013-10-02T22:28:49 < jpa-> nice thing about that is that i can easily have the CPU wake up on any button press (it's hooked to PA0/WKUP on stm32l151)
2013-10-02T22:30:09 < Thorn> jpa-: you should have used DTMF frequencies and a little DSP in the MCU to detect those. your method is not hacky enough.
2013-10-02T22:35:05 < qyx_> jpa-: lol
2013-10-02T22:35:46 < qyx_> even better would be to save adc input and use some form of charge transfer method and capacitors!

2013-10-02T23:51:49 < zyp> you think replacing the device side is going to solve your host problems?
2013-10-02T23:51:57 < zyp> good luck with that :p
2013-10-02T23:52:01 < karlp> of course! it's definitely the software's problem
2013-10-02T23:52:11  * karlp giggles
2013-10-02T23:53:39 < Posterdati> the problem is that transfer is slow...
2013-10-02T23:53:55 < Posterdati> no matter what I do from host side
2013-10-02T23:55:17 < Posterdati> when some packets were received they are always 4 bytes long!
2013-10-02T23:57:23 < zyp> 4 bytes?
2013-10-02T23:57:35 < Posterdati> yes
2013-10-02T23:57:37 < zyp> sounds like you've fucked up writing then
2013-10-02T23:57:51 < Posterdati> I placed 512 bytes transfer on the host
2013-10-02T23:58:34 < zyp> sure
2013-10-02T23:58:53 < zyp> but it shouldn't get 4-byte packets unless the device is sending 4-byte packets
2013-10-02T23:59:20 < zyp> which the device wouldn't unless you fuck up something
2013-10-02T23:59:42 < zyp> like writing a packet before the previous one was sent

2013-10-03T05:46:06 < dongs> you might get better information out of a map file.
2013-10-03T05:50:48 < talsit> in which way?
2013-10-03T05:51:34 < talsit> my map contains a lot of info, and the sizes of memories, but unless i want to start adding up parts, what will that give me that eabi-size won't?
2013-10-03T05:57:39 < gxti> if you want to exclude CCM you have to go more fine-grained than what 'size' does, e.g. readelf -S
2013-10-03T05:58:04 < talsit> my current linker script doesn't put anything in CCM
2013-10-03T05:58:30 < talsit> so i'm guessing all my available RAM is 128kB
2013-10-03T06:00:13 < gxti> it looks like that part has 128k total non-ccm RAM.
2013-10-03T06:00:52 < gxti> and you have 80k of crap
2013-10-03T06:02:21 < talsit> gxti: 80kB of buffers, you mean?

2013-10-03T06:04:41 < gxti> whatever is in data and bss.
2013-10-03T06:04:58 < gxti> i don't know how to answer your question because you don't know how to ask it specifically enough :p
2013-10-03T06:06:02 < talsit> is the free non-ccm RAM: 128kB - (.data + .bss)? or just .bss?
2013-10-03T06:06:44 < ohsix> that depends on the linker script
2013-10-03T06:06:48 < talsit> that's what i meant, so, cool, you answered, cheers
2013-10-03T06:07:14 < ohsix> and if you look at it, it has the layout and sizes for stuff
2013-10-03T06:08:43 < ohsix> ld -verbose will show the linker script
2013-10-03T06:09:07 < ohsix> what's ccm, btw, i don't know jack about the stm32
2013-10-03T06:09:11 < talsit> reading it now, cool
2013-10-03T06:09:17 < talsit> core-coupled-memory
2013-10-03T06:09:21 < ohsix> ah
2013-10-03T06:09:23 < talsit> you can't DMA from/to it
2013-10-03T06:09:42 < ohsix> there was something like that on the arm7 that i am familiar with
2013-10-03T06:09:52 < talsit> so some linker scripts disable it until you know what you're doing
2013-10-03T06:10:06 < ohsix> normally you have to name a section for that
2013-10-03T06:10:14 < ohsix> it's not just used until theres none left or something
2013-10-03T06:11:09 < ohsix> and then you use that with __attribute__((section ("whatever")))
2013-10-03T06:11:28 < ohsix> or a linker script putting all of .text in there or something
2013-10-03T06:11:37 < talsit> right, that kinda makes sense now
2013-10-03T06:11:49 < talsit> just wondering what i have that could go in CCM easily
2013-10-03T06:12:12 < ohsix> use a profiler, there's usually not much return on just sticking things in there
2013-10-03T06:12:25 < ohsix> there will be operations you want to use the space thats left for, too
2013-10-03T06:12:48 < talsit> i basically need to leave as much normal-ram for write buffers for SD card
2013-10-03T06:13:03 < talsit> since i'm custantly streaming and generating about 100kB/s
2013-10-03T06:13:22 < talsit> and wanted to intelligently measure how big i can make the buffer
2013-10-03T06:13:39 < talsit> instead of using my usual technique, which is increasing it until it no longer links
2013-10-03T06:13:55 < ohsix> is there a reason it's called TCM in certain context, and CCM in others?
2013-10-03T06:14:08 < talsit> that's the "T" there?
2013-10-03T06:14:13 < ohsix> tightly
2013-10-03T06:14:43 < ohsix> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0338g/Chdhbjjb.html
2013-10-03T06:14:52 < talsit> ah
2013-10-03T06:15:39 < ohsix> fwiw i only got like 10% improvement by shoving random junk in there with __attribute__ (memory an text)
2013-10-03T06:16:01 < talsit> is that memory faster?
2013-10-03T06:16:12 < ohsix> but i only mention that in light of how much better it is if you're not just picking stuff to put in there in preference to something
2013-10-03T06:16:16 < ohsix> ya, lots
2013-10-03T06:16:33 < ohsix> i forget most of the details though
2013-10-03T06:16:45 < talsit> i'm currently only using about 3% of CPU, so i'm more concerned with buffer space
2013-10-03T06:16:52 < talsit> but if i can shove things in there, i will
2013-10-03T06:19:21 < ohsix> hm
2013-10-03T06:19:40 < ohsix> i dunno how to tell gcc the stuff you will put in that section won't benefit as much from the work it does to help the cache
2013-10-03T06:20:12 < gxti> speaking of linker scripts, how would i go about splitting up flash into two chunks with a gap between them? e.g. one 2k chunk at 0, then a bigger chunk at 100k+ offset
2013-10-03T06:20:49 < gxti> bonus points if i can make it pack the second chunk starting at the end and growing down
2013-10-03T06:21:38 < ohsix> dunno, linker scripts are voodoo to me, mostly because i haven't had to write one where i had all the details
2013-10-03T06:23:06 < ohsix> generally tou define the area name & offset and then you should just be able to define both areas and have a whole in the section they actually end up in
2013-10-03T06:29:03 < dongs> no DMA in CCM.
2013-10-03T06:29:21 < dongs> makes it slightly less useful than lunix on desktop.

2013-10-03T06:35:42 < talsit> but i was getting massive delays when writing to it
2013-10-03T06:36:00 < talsit> by massive i mean, massive for only using a 64kB buffer
2013-10-03T06:36:28 < dongs> i doubt you need anything beyond few kb buffer with fatfs.
2013-10-03T06:36:31 < dongs> youre doing something wrong.
2013-10-03T06:36:31 < talsit> so i was dropping about 1% of packets, instead of 0.0001% as with my sandisk extreme

2013-10-03T06:36:37 < gxti> ohsix: doesn't look like it will pack around it though, just start again after the gap symbol
2013-10-03T06:37:23 < ohsix> gxti: do you mean it won't pack say, if it were REGION1, REGIONSKIP, REGION2, region1 wouldn't be full before region2 starts getting things placed in it?

2013-10-03T06:39:31 < talsit> dongs is that continuous or burst?
2013-10-03T06:39:42 < gxti> ohsix: maybe i have to get rid of the "> flash" after every section that i have now
2013-10-03T06:39:48 < ohsix> talsit: how is the card formatted? did you use the panasonic formatter or what, and did you leave any extra space for overprovisioning?
2013-10-03T06:39:50 < dongs> how is that relevant?
2013-10-03T06:40:08 < dongs> how do you measure "burst" when youre only writing few k at a time
2013-10-03T06:40:12 < ohsix> dongs: it's the difference from 30mb/s for 1mb and for 50mb
2013-10-03T06:40:26 < talsit> because the sd cards have a buffer on them, and every X bytes, they go to a new sector, inflicting a stall
2013-10-03T06:40:31 < talsit> up to 500ms
2013-10-03T06:40:38 < dongs> uh
2013-10-03T06:40:43 < ohsix> it might actually have high delays due to the low write rate
2013-10-03T06:42:08 < ohsix> talsit: that doesn't really explain how flash works, it can be like that, but it probably hasn't practically been since 1999

2013-10-03T06:44:28 < talsit> i'm formatting my cards with standard windows format, which is what i expect the people using my box will be using
2013-10-03T06:44:48 < ohsix> ah don't do that
2013-10-03T06:45:21 < ohsix> the cards are rather devious about things they do to optimize the speeds, one is actually being aware of FAT, and needing to have stuff aligned
2013-10-03T06:45:46 < ohsix> btw, cards formatted with something other than like, the panasonic formatter actually aren't in spec and technically can't be called an sd card ;D
2013-10-03T06:46:09 < dongs> chinese "32gb" cards are aware of fat too.
2013-10-03T06:46:30 < ohsix> yes, they can fake rather well that there's only 512mb of actual flash in that card

2013-10-03T06:49:34 < gxti> digital cameras often have a format function builtin, you could do that if it makes sense for your thingy
2013-10-03T06:49:55 < ohsix> yea, and you can't really control for how they'd behave if they're not properly formatted either
2013-10-03T06:50:12 < ohsix> they'll be compliant when they're new, people shouldn't format them needlessly
2013-10-03T06:50:15 < gxti> ohsix: tried this, doesn't seem to attempt to pack at all: http://pastebin.com/z2Gm352c
2013-10-03T06:50:19 < talsit> i do have a format function, the FatFS one, but i can't *always* format it, most of the time it will come however it comes
2013-10-03T06:50:22 < gxti> ohsix: it just attempts to put everything in flash1 and fails
2013-10-03T06:50:30 < ohsix> the panasonic formatter lets you format with huge sector sizes and makes sure they're all aligned and stuff
2013-10-03T06:51:01 < ohsix> talsit: fatfs could certainly be told to hew closer to the spec
2013-10-03T06:51:48 < talsit> but that will be the exception
2013-10-03T06:51:55 < gxti> i think since i really want to make the second hunk sit at the end of flash regardless of how much code i have, i may end up writing a tool to generate the linker script with specific symbols anyway, in addition to choosing how big flash2 is
2013-10-03T06:52:39 < ohsix> hm i dunno, shouldn't those be sections not memory
2013-10-03T06:53:17 < ohsix> talsit: i guess i can't impress upon you just how bad all io will be if they're not properly formatted, it is very very very very bad, are you going to add dram to cover as many cases as you can?
2013-10-03T06:53:50 < ohsix> and even if you do, your write rates are going to be wildly different
2013-10-03T06:54:28 < talsit> i understand that the best thing would be to pre-allocate 1mb blocks directly on the card and bypass FAT directly
2013-10-03T06:54:45 < talsit> but given the use of this, people will format it however they want, and expect it to work
2013-10-03T06:55:03 < talsit> i can deal with dropping some data, but want to minimise it
2013-10-03T06:55:07 < ohsix> that's not the best thing to do though
2013-10-03T06:55:18 < ohsix> the flash controllers know about fat, you'd bypass any benefit of that
2013-10-03T06:55:23 < talsit> i was thinking of 1MB external SRAM in v2
2013-10-03T06:55:42 < talsit> which is enough for about 10s of data
2013-10-03T06:55:59 < ohsix> think about 'however they want', if they format it as ntfs is it going to work?
2013-10-03T06:56:13 < dongs> format as zfs
2013-10-03T06:56:52 < talsit> no, obviously not, but if they, instead of formatting it, they just delete all files and call it "formatted", then that's what they will do
2013-10-03T06:57:00 < ohsix> there's a spectrum of things you should account for
2013-10-03T06:57:03 < talsit> most likely, they will use osx for "formatting"
2013-10-03T06:57:22 < ohsix> deleting all files is ok, even preferrable if the last format (or if it was new) was SD compliant
2013-10-03T06:57:50 < ohsix> the problems occur when the block size and alignment change, the fat is in the wrong place, stuff like that
2013-10-03T06:57:56 < dongs> u gon have hidden __MACOSX folders everyfuckingwehre

2013-10-03T07:05:51 < upgrdman> ohsix: ? the filesystem is separate from the SD card. a SD card is a block device. you can treat the bytes however you damn well please
2013-10-03T07:06:04 < talsit> ohsix: it kinda is, because users won't care, they will use their macbook, format it, and if it doesn't work, then they'll blame me, end of story on that
2013-10-03T07:06:16 < ohsix> upgrdman: not if you want to use it as if the marked speeds were real, or the lifetime would be the same

2013-10-03T07:06:22 < ohsix> heh

2013-10-03T07:12:57 < dongs> R0b0t1: you can choose, it has 2 channels, and either one can be serial or i2c or spi
2013-10-03T07:13:11 < R0b0t1> neat
2013-10-03T07:13:19 < dongs> the best part i think is capsense junks
2013-10-03T07:13:47 < dongs> the channels can be independently configured to UART, I2C or SPI interfaces, and simultaneously connect two devices with different serial interfaces.
2013-10-03T07:14:54 < dongs> for sure
2013-10-03T07:15:54 < ohsix> well i can't find a leaked copy of the sd specs to point out what counts as compliant, but it's in there; if you ever find yourself with access to them
2013-10-03T07:18:49 < R0b0t1> The SD card spec includes an interface, but from a practical standpoint (as in, probably not specified beyond this point) all that matters is the block device interface
2013-10-03T07:21:44 < ohsix> hehhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh

2013-10-03T07:53:55 < ohsix> finding out how to make fatfs do it would be pretty simple, and useful, it might already if you use the right cluster sizes and stuff
2013-10-03T07:54:35 < ohsix> vista+ and tools from linux as of 2010 or so will usually get the block alignment/size right
2013-10-03T07:54:47 < ohsix> that's 90% of the way there

2013-10-03T07:59:59 < talsit> that's before panasonic formatting, now will try re-formatted
2013-10-03T08:01:05 < ohsix> if you want me to understand what the drop rate means i'd need more information; but i think i know what you're expecting
2013-10-03T08:01:28 < ohsix> do you have a histogram or something of the delays?
2013-10-03T08:02:05 < talsit> when i write to the sony, the writing stalls enough for it not to be able to keep up with the streaming, so i will not write out new packets until the writing has finished

2013-10-03T09:02:00 < talsit> thanks for chasing things up, appreciate it
2013-10-03T09:03:02 < ohsix> i'm only slightly less interested than you are in why the sd card is doing that ;D
2013-10-03T09:03:28 < ohsix> did the flush size change anything?
2013-10-03T09:03:34 < talsit> from my understanding, when you go past a certain block or sector, it stalls to prepare the next
2013-10-03T09:04:08 < ohsix> it's way more complex than that, it's certainly whats causing the stall, but 'prepare' is often not erasing an entire sector and rewriting things
2013-10-03T09:04:41 < ohsix> internally there is sector remapping and stuff to do wear levelling, any correlation you'd see is not much more than coincidence
2013-10-03T09:05:34 < talsit> i've heard lots of horror stories all over the place with SD cards - lots of stalls in inappropriate times
2013-10-03T09:05:59 < ohsix> of course, and knowing nothing about the host or the cards means basically nothing
2013-10-03T09:06:44 < ohsix> for all we know the controller might have been resetting itself or something

2013-10-03T09:09:50 < ohsix> also, chibios has scheduling implications
2013-10-03T09:10:04 < ohsix> i dunno if in your situation there's stuff being held up long enough to mess with things
2013-10-03T09:10:28 < ohsix> rtos stuff is not complex, but you need to check pretty much on a case by case basis
2013-10-03T09:10:42 < talsit> ohsix: the difference between flushes is not significant
2013-10-03T09:10:50 < ohsix> ok
2013-10-03T09:10:58 < talsit> heap, chibios may be stuffing things up
2013-10-03T09:11:03 < ohsix> so at the very least, you just saved yourself a lot of memory
2013-10-03T09:12:38 < ohsix> do you see pauses with random io?
2013-10-03T09:12:47 < talsit> but, on a test between a cheap sony card and a decent sandisk card, with absolutely no changes is that the sony would drop packets every so often (4 packets every 30s or so), and the sandisk would drop a few rarely (maybe 20 once an hour)
2013-10-03T09:13:13 < talsit> no CODE changes
2013-10-03T09:13:23 < dongs> code is shit
2013-10-03T09:13:48 < talsit> ok, i'll make an ASIC next time, thanks
2013-10-03T09:15:13 < ohsix> heh what do you think they do asics with
2013-10-03T09:15:41 < talsit> ohsix: i didn't save any ram, since i still write at the same rate/speed from the same buffer, i just changed the rate of the flush()
2013-10-03T09:15:44 < ohsix> easy way to rule out the code or the card is benchmarking it and getting a histogram

2013-10-03T09:17:53 < ohsix> if you are able to flush more often i dunno what you'd buffer for

2013-10-03T09:18:35 < talsit> i can either flush at the end of each buffer or on 1mb
2013-10-03T09:18:55 < talsit> as in, that's what i tested
2013-10-03T09:19:15 < talsit> i can buffer any more
2013-10-03T09:22:09 < ohsix> so you aren't buffering for the sake of bad sd cards, or your data is highly irregular?
2013-10-03T09:22:24 < dongs> pro irc ee advice in progress, sshhh
2013-10-03T09:22:52 < talsit> i'm trying to buffer in order to write bigger chunks, less often
2013-10-03T09:23:10 < talsit> my data is always 512bytes at 200Hz
2013-10-03T09:23:13 < dongs> card should have no problem writing 512byte blocks, often.
2013-10-03T09:23:14 < ohsix> right, but there's not much return after buffering like 64k
2013-10-03T09:23:34 < ohsix> changing how often you flush changes how much you buffer given the same rate
2013-10-03T09:24:10 < dongs> um
2013-10-03T09:24:11 < dongs> youre saying
2013-10-03T09:24:20 < dongs> your code FAILS to write sustained at 100k/sec tocard??
2013-10-03T09:24:22 < talsit> not me buffering, but the sd card buffering, right?
2013-10-03T09:24:26 < dongs> 512bytes*200Hz = 100kib/sec
2013-10-03T09:24:31 < talsit> no, my code does not fail

2013-10-03T09:25:20 < dongs> dude, 100kilobytes
2013-10-03T09:25:25 < dongs> is *nothing*
2013-10-03T09:25:37 < ohsix> and what are you actually buffering and how large are your writes?
2013-10-03T09:25:45 < dongs> i wouldnt evne buffer anything at all
2013-10-03T09:25:51 < talsit> every 30s or so, the card stalls for about 250ms
2013-10-03T09:25:56 < dongs> just push 512byte blocks out to fatfs
2013-10-03T09:26:03 < ohsix> you'd need to buffer at least 512 bytes ;D
2013-10-03T09:26:08 < dongs> well yeah
2013-10-03T09:26:31 < talsit> my good card, it stalls maybe once an hour
2013-10-03T09:26:54 < dongs> i thought this was some 5meg/sec or something that was failing.
2013-10-03T09:26:58 < dongs> if 100k fails, look at your code.
2013-10-03T09:27:01 < dongs> has nothing to do with cards.
2013-10-03T09:27:19 < talsit> really? then how can the same code have different effects on different cards?
2013-10-03T09:27:35 < ohsix> there are several things in play, your code is a small part

2013-10-03T09:30:37 < ohsix> all he knows is that sometimes it's unable to do it
2013-10-03T09:30:41 < ohsix> and nothing else
2013-10-03T09:31:13 < dongs> wghere teh fuck did you find a 250gig hdd mang
2013-10-03T09:31:14 < talsit> dongs, so you're saying that SD cards *can't* stall when writing?
2013-10-03T09:31:33 < ohsix> no, they can
2013-10-03T09:31:40 < dongs> " This was superseded by the Speed Class Rating, which guarantees a minimum rate at which data can be written to the card."
2013-10-03T09:31:50 < ohsix> but going 'hey sometimes this happens' and not knowing why, or knowing one plausible reason why, isn't a good place to stop
2013-10-03T09:31:51 < dongs> "guarantees" "minimum"
2013-10-03T09:31:55 < talsit> ok, how long can the stall be?
2013-10-03T09:32:16 < dongs> Speed Classes 2, 4, and 6 assert that the card supports the respective number of megabytes per second as a minimum sustained write speed for a card in a fragmented state.
2013-10-03T09:32:18 < ohsix> you'd have to look to the sd specs to see how large it can be
2013-10-03T09:32:57 < ohsix> dongs: there are all sorts of things that can just be slow when the write rate is low, mostly stuff that makes it clever at higher speeds
2013-10-03T09:33:57 < talsit> if the card stalls for more than 400ms at *any* point, i will lose a packet @ ~100kB/s
2013-10-03T09:35:31 < ohsix> 400ms is super unlikely length of time for anything the sd card may be doing
2013-10-03T09:35:46 < ohsix> like, even the most ignorant sector erase and rewrite
2013-10-03T09:36:52 < ohsix> but if you're not willing to suspect your code, i dunno how you'll investigate yours and the other code involved
2013-10-03T09:37:26 < ohsix> if you actually buffered a megabyte, you could get your write rates up to a few mb/s, maybe the problem would go away

2013-10-03T09:37:54 < talsit> if i write to the card as fast as i possibly can, i can get a throuput of about 5-8MB/s
2013-10-03T09:38:01 < talsit> withs periodic stalls
2013-10-03T09:38:03 < ohsix> i don't think fatfs is doing what you think if you have it do the buffering and run sync every once and a while
2013-10-03T09:38:31 < talsit> i'll strip down a version of the code that *just* writes the same 48kB buffer continuously to test it
2013-10-03T09:38:39 < talsit> and store the times
2013-10-03T09:40:03 < dongs>  < R2COM> maybe his card is arduino controlled thats why
2013-10-03T09:40:12 < dongs> pretty sure even arduino can handle > 100k/sec writes
2013-10-03T09:41:46 < ohsix> derp, all the measurement stuff on osx is done with dtrace, and that's good; but i can't literally tell you how to use it
2013-10-03T09:47:25 < ohsix> you can't test the code in isolation without a lot of work, so test the sd card
2013-10-03T09:47:33 < talsit> i am
2013-10-03T09:47:38 < talsit> i'm stripping down a version
2013-10-03T09:47:41 < talsit> that *just* writes
2013-10-03T09:48:07 < ohsix> https://code.google.com/p/ioping/ no histogram but has min/max/avg/mdev
2013-10-03T09:50:40 < ohsix> i think you misunderstand what i mean by isolate
2013-10-03T09:51:15 < ohsix> there are about 5 things in play, chibios (other threads, scheduling)/fatfs/the sd card/the sd bus code
2013-10-03T09:51:29 < ohsix> you don't isolate any of them doing that
2013-10-03T09:52:02 < ohsix> if i knew you could get a scheduling latency histogram from chibios i'd suggest that as well, or time running with irqs disabled

2013-10-03T09:53:17 < talsit> then... i don't know what you mean
2013-10-03T09:54:54 < ohsix> put the sd card in a host that's not likely to misbehave, like osx or linux or windows, get a io latency histogram
2013-10-03T09:55:06 < ohsix> if the card has a problem you will see spikes in the histogram
2013-10-03T09:55:30 < ohsix> once the card(s) are ruled out, we can find a way to break up chibios into testable parts

2013-10-03T12:25:32 < zyp> Posterdati, you'd probably save a lot of time if you had a usb analyzer so you could tell exactly what is going wrong on the bus level :p
2013-10-03T12:26:06 < Posterdati> yes, haven't got one
2013-10-03T12:27:54 < trepidaciousMBR> jpa-: I sort of nearly solved that serial problem, turns out if I don't have an event listener on the serial driver, I get lots of timeouts, if I DO have one registered and waiting for events (then doing absolutely nothing) it all works fine. Presumably I'm STILL doing something wrong somewhere ;)

2013-10-03T17:29:19 < gxti> the good news is that cpus don't actually run x86 anymore, it's all emulated :P

2013-10-03T17:30:08 < gxti> emulated isn't quite the right word i guess
2013-10-03T17:30:13 < MrMobius> i thought it got chopped up and made into a kind of RISC format first

2013-10-03T18:16:47 < GargantuaSauce> One of Urbit’s problems is that we don’t exactly have a word for what Urbit is. If there is such a word, it somehow means both “operating system” and “network protocol,” while somehow also implying “functional” and “deterministic.”
2013-10-03T18:17:19 < GargantuaSauce> Worse yet, Hoon is not written in anything normal. It’s written in Hoon. To be precise - the Hoon compiler compiles itself to a much simpler automaton, Nock.

2013-10-04T00:45:26 < ohsix> gxti: emulated -> microcoded
2013-10-04T00:50:27 < ohsix> As a network protocol, we could call Urbit a “seven-layer protocol” - that is, a protocol that specifies the complete semantics of the general-purpose computer that processes it. As any decent IETF ninja will tell you, this is a very bad idea for all sorts of extremely obvious reasons.
2013-10-04T00:51:05 < ohsix> you get the impression that he talks aobut himself in the third person too
2013-10-04T00:52:13 < GargantuaSauce> one might get that impression, yes
2013-10-04T00:52:49 < qyx_> Laurenceb: i use dxf import ulp, works okay.. you can save dxf in inkscape
2013-10-04T00:58:12 < gxti> that was strange... apparently a soft reset of the PHY on powerup isn't enough, have to toggle the reset line. otherwise it was coming up deaf+mute every third time power was applied or so, but kept working/notworking no matter how many times the mcu was reset
2013-10-04T01:00:35 < ohsix> what sort of phy on what
2013-10-04T01:05:38 < karlp> where's the schematic of that BMPv2 that's floating around?
2013-10-04T01:06:10 < karlp> never mind, found it.
2013-10-04T01:07:52 < karlp> emeb: was there anything on that v2 board you didn't like or got wrong?
2013-10-04T01:08:09 < zyp> the fet, you might want to not populate it
2013-10-04T01:08:28 < zyp> because last time I checked BMP don't even control it, so the gate floats
2013-10-04T01:08:33 < emeb> karlp: I think the circuit is fine. As zyp notes, that power FET causes trouble.
2013-10-04T01:08:45 < emeb> also, the legend for the LED meanings isn't quite right.
2013-10-04T01:08:53 < zyp> and if the target is powered and the BMP is not, you'll get a reverse flow through the FET messing up
2013-10-04T01:08:59 < karlp> PWR_RR for target power?
2013-10-04T01:09:28 < karlp> I'm hacking up a rpi->arm 20 pin + arm10pin jtag plate, only really looking at the multi connector stuff
2013-10-04T01:09:53 < emeb> that stuff should all be fine
2013-10-04T01:10:16 < karlp> so nRESET on the 10pin is SRST in jtag world then? (not TRST?)
2013-10-04T01:10:36 < emeb> yeah
2013-10-04T01:11:33 < gxti> also i would recommend using a fet to pull down srst instead of connecting it directly
2013-10-04T01:12:09 < gxti> er, i guess open-drain is fine. but don't push-pull it.
2013-10-04T01:12:33 < zyp> true
2013-10-04T01:12:50 < karlp> gonna get wired straight to a raspberry pi pin that openocd will drive...
2013-10-04T01:13:00 < karlp> a fet to pull down? what's controlling the fet?

2013-10-04T01:13:47 < emeb> I guess you could change that with software setup of the GPIO
2013-10-04T01:13:51 < gxti> any gpio
2013-10-04T01:14:16 < gxti> you don't want to push srst high because it blocks stm32 from triggering a reset internally
2013-10-04T01:14:36 < gxti> software reset, brownout detection, whatever
2013-10-04T01:15:05 < karlp> blegh
2013-10-04T01:15:24  * karlp goes to check the stlink schematic
2013-10-04T01:15:40 < gxti> that had me scratching my head for a good 5 minutes, because the code used to work and then at some point i upgraded my bmp and started connecting the srst line and it could no longer reset
2013-10-04T01:15:54 < gxti> you don't have to use a fet if you can do open-drain gpio

2013-10-04T01:20:06 < gxti> not yet, no
2013-10-04T01:20:19 < emeb> how did you work around? Just disconnect srst?
2013-10-04T01:20:25 < gxti> yeah
2013-10-04T01:21:05 < zyp> last time I dicked around with the bmp code, it didn't even touch srst
2013-10-04T01:21:06  * emeb wonders how many little glitches are in bmp that are well known but not fixed in firmware yet
2013-10-04T01:21:10 < gxti> it would be trivial to make it open-drain, but it only just now occurred to me
2013-10-04T01:21:36 < karlp> zyp does it only use trst or what?
2013-10-04T01:21:40 < zyp> gxti, do so and submit a pull request, then you've solved the problem for everyone
2013-10-04T01:21:42 < karlp> doesn't the 10 pin connector only have srst?
2013-10-04T01:21:57 < zyp> karlp, it doesn't use any hard reset
2013-10-04T01:22:26 < emeb> zyp: did you push your fixes for the MacOS USB descriptors?
2013-10-04T01:22:26 < karlp> so emeb's trace labeld RST is actually just sitting there doing nothing?
2013-10-04T01:22:57 < gxti> i use stlink 6-pin connector for swd, it has srst and not trst (trst is not defined for swd)
2013-10-04T01:22:58 < zyp> I believe it sets the sysresetreq bit just like the software would to self-reset
2013-10-04T01:23:10 < zyp> karlp, at least in old versions it did
2013-10-04T01:23:26 < zyp> but I think somebody added srst so it could reset sleeping chips and so on
2013-10-04T01:23:43 < gxti> it has the option to now, but even when it's off it's pushing srst high
2013-10-04T01:23:53 < zyp> gxti, then that's a bug
2013-10-04T01:24:04 < zyp> again, submit a pull request
2013-10-04T01:24:31 < zyp> emeb, I don't think so, it's more «workarounds» than fixes
2013-10-04T01:25:05 < zyp> IIRC they are only needed for 10.6 or older, so I don't have any need for them any more anyway
2013-10-04T01:25:15 < emeb> zyp: true
2013-10-04T01:25:53 < emeb> but some of us are dinosaurs and don't plan to upgrade the OS, so they're handy workarounds. Maybe #ifdef them & push or something.
2013-10-04T01:26:41 < gxti> heh, RTFSing and it is in open-drain mode for stlink platform but not native
2013-10-04T01:28:00 < emeb> wtf?
2013-10-04T01:28:00 < gxti> looks like maybe some hardware is intended to use a fet. i spun my own boards so it's possible i made a mistake, checking now
2013-10-04T01:28:27 < emeb> no boards that I know of you external fet
2013-10-04T01:28:36 < emeb> s/you/use/
2013-10-04T01:28:42 < gxti> gpio_set_val(SRST_PORT, SRST_PIN, platform_hwversion() > 0);
2013-10-04T01:28:50 < gxti> similar logic in the srst_set_val function as well
2013-10-04T01:29:11 < Laurenceb_> wtf
2013-10-04T01:29:15 < Laurenceb_> still eagle raging
2013-10-04T01:29:26 < Laurenceb_> what could cause a "drill distance" error?
2013-10-04T01:29:40 < Laurenceb_> the drill is miles from the edge of the board
2013-10-04T01:29:57 < Laurenceb_> oh wait... how does eagle know if the drill hole is inside of outside the board?
2013-10-04T01:30:08 < gxti> drills too close?
2013-10-04T01:30:14 < Laurenceb_> i'm designing a really complex flexi pcb, maybe it got confused
2013-10-04T01:30:31 < Laurenceb_> im going to try some experiments to see if eagle gets confused about inside/outside
2013-10-04T01:32:27 < zyp> does eagle even have a notion of inside/outside?
2013-10-04T01:33:43 < gxti> yep the original bmp uses a npn to pull srst
2013-10-04T01:34:01 < emeb> interesting
2013-10-04T01:34:01 < zyp> the original bmp also use a voltage translator
2013-10-04T01:34:24 < gxti> so i guess whoever added srst stuff was too lazy to set it opendrain for everything else
2013-10-04T01:34:24 < emeb> zyp is the only person I know with an original bmp
2013-10-04T01:34:55 < zyp> I'm also the only person I know with an original bmp
2013-10-04T01:35:08 < zyp> I don't know where it is though :p

2013-10-04T01:38:57 < dongs> zyp, i repeated teh autorouter test from those faggots
2013-10-04T01:39:00 < dongs> i couldn't make it to do a via
2013-10-04T01:39:08 < dongs> http://i.imgur.com/YU106AV.png just setup same test
2013-10-04T01:39:23 < dongs> and yes i tried moving RN closer to chip, further, up, down etc.
2013-10-04T01:39:27 < dongs> it always just does what  I would expect.
2013-10-04T01:40:05 < zyp> :p
2013-10-04T01:40:33 < karlp> people trolling about tool choice on the ninternet? hehe
2013-10-04T01:40:41 < Laurenceb_> arg
2013-10-04T01:40:53 < Laurenceb_> eagle is not designed for complex flexi pcb
2013-10-04T01:41:06 < ohsix> that doesn't even look close to the same
2013-10-04T01:41:07 < Laurenceb_> a folding simulator would be nice too
2013-10-04T01:41:15 < zyp> Laurenceb_, what a surprise
2013-10-04T01:41:34 < ohsix> you haxored the trace width so whatever trace distance stuff they had going on for that inner trace wouldn't be in play
2013-10-04T01:42:09 < dongs> Irregular shaped vias tend to knock the electrons around and bang them up a bit. This will produce an edgier, rougher sound.
2013-10-04T01:42:12 < dongs> On the other hand round vias are more gentle on the electrons and produce a smoother result. For the perfect treatment you should use an oval shape with the pointy end pointing against the electron flow. This gently guides the electrons into the via.
2013-10-04T01:42:16 < dongs> This is also the reason for the teardrop shape you sometimes see on circuit boards.
2013-10-04T01:42:19 < dongs> haha
2013-10-04T01:42:21 < dongs> ohsix: this is my default trace width
2013-10-04T01:42:23 < Laurenceb_> epic lolling
2013-10-04T01:42:29 < dongs> i'm sorry if your chinese $10/10 board house can't handle 8mil traces
2013-10-04T01:42:42 < dongs> or 6 mil
2013-10-04T01:42:43 < dongs> or hwatever
2013-10-04T01:42:54 < zyp> dongs, what the fuck :p
2013-10-04T01:43:24 < ohsix> bang them up a bit, and if you measured it as sound, maybe; but it's nothing anyone with human ears would notice
2013-10-04T01:43:46 < ohsix> dongs: well, you have to change the trace width to have any hope of the same thing happening
2013-10-04T01:43:53 < ohsix> and put them closer together
2013-10-04T01:43:57 < dongs> i did.
2013-10-04T01:44:56 < dongs> http://i.imgur.com/pv62Qkq.png
2013-10-04T01:44:57 < dongs> 10mil.
2013-10-04T01:45:00 < zyp> why are you so set on reproducing it anyway?
2013-10-04T01:45:14 < dongs> zyp: because the faggot is wrong.
2013-10-04T01:45:20 < dongs> OMG SOMEONE IS WRONG ON THE INTERNET.
2013-10-04T01:45:21 < ohsix> 'wrong'
2013-10-04T01:45:31 < zyp> oh well
2013-10-04T01:45:34 < ohsix> was anything but the png ever posted?
2013-10-04T01:45:49 < ohsix> 'this is weird' is way more likely than 'THIS IS THE ONLY THING THAT CAN HAPPEN'
2013-10-04T01:46:11 < ohsix> plus you could probably trust either of you to flip it the other way
2013-10-04T01:46:42 < dongs> the point of this story is
2013-10-04T01:46:46 < dongs> anyone who uses autorouter is a faggot anyway.
2013-10-04T01:46:50 < gxti> ^^^
2013-10-04T01:46:52 < ohsix> story???//
2013-10-04T01:47:10 < ohsix> the autorouter gets you 80% of the way there on larger nets
2013-10-04T01:47:13 < dongs> story/linked reddit thread/whatever
2013-10-04T01:47:31 < gxti> it takes me less clicks to route that manually than someone who spends all day dicking with the autorouter, and that's even without using altium's route-multiple-nets-at-once feature :p
2013-10-04T01:48:03 < zyp> the route multiple feature is pretty nice though
2013-10-04T01:48:31 < gxti> i don't use it that often, i don't do a lot of busses in my designs so far
2013-10-04T01:48:38 < gxti> but it's nifty anyway
2013-10-04T01:48:44 < ohsix> plus it can do drc while it does shit so you don't have to do it all

2013-10-04T01:52:30 < dongs> win2k will need > 8meg ram
2013-10-04T01:53:12 < dongs> o wait wat theres 256megs
2013-10-04T01:53:29 < gxti> i think win2k requires 64mb

2013-10-04T01:55:03 < emeb> so you can plug in yer headphones and listen to the bits
2013-10-04T01:55:36 < ohsix> kind of cool there's a pci-e connector on there
2013-10-04T01:55:59 < zyp> that's for next generation arduino shields
2013-10-04T01:56:01 < gxti> 80% of the time mini-pcie is just usb
2013-10-04T01:56:26 < gxti> on low-power stuff anyway
2013-10-04T01:56:35 < dongs> wel,l that says minipcie specifically
2013-10-04T01:56:41 < gxti> vendors lie
2013-10-04T01:56:50 < ohsix> ya it's not like expresscard or anything
2013-10-04T01:56:59 < ohsix> the diagram does show usb connected to it tho
2013-10-04T01:57:12 < gxti> the connector carries both but it's uncommon for the pci-e lanes to actually be there, especially for atoms
2013-10-04T01:57:23 < zyp> both minipcie and expresscard specs specifies both pcie and usb
2013-10-04T01:57:41 < zyp> gxti, the block diagram says the minipcie socket has both
2013-10-04T01:57:47 < zyp> but yeah, you are right
2013-10-04T01:57:55 < gxti> i guess intel lies less then
2013-10-04T01:58:28 < zyp> no msata though :p
2013-10-04T01:58:52 < zyp> I like the pcie/msata combo that some modern stuff comes with
2013-10-04T01:59:22 < zyp> got an msata ssd in the new server I picked up a couple of months ago
2013-10-04T02:00:39 < gxti> it's the mini-itx crap that generally has the connector with just usb, because they're cheap and the platform probably doesn't even *have* pci-e
2013-10-04T02:01:09 < zyp> yep
2013-10-04T02:01:20 < zyp> I had an arm geode based board like that once
2013-10-04T02:01:52 < zyp> the socket was meant for 3g modems, which usually only use usb anyway

2013-10-04T02:05:48 < gxti> using a stlink style 6-pin header, but might change that soon
2013-10-04T02:06:27 < zyp> I'm probably gonna put tag connect on everything I design from now on
2013-10-04T02:06:45 < karlp> well, now that you ahve a tag connect cable, sure :)
2013-10-04T02:07:19 < talsit> i put a 10-pin through hole for the little mill-max pogo pins, it's awesome
2013-10-04T02:07:34 < talsit> the 1.27mm ones
2013-10-04T02:07:54 < zyp> sounds like reinventing tag connect
2013-10-04T02:08:17 < gxti> sounds like avoiding vendor lock-in :P
2013-10-04T02:08:23 < talsit> except that it uses the same 10pin cortex pinout
2013-10-04T02:08:49 < talsit> and my footprint accomodates solderpads for soldering in an actual header for development
2013-10-04T02:08:57 < talsit> and you can leave it out for production
2013-10-04T02:09:07 < zyp> fair enough
2013-10-04T02:09:30 < zyp> I just put pads for a smt connector next to the tag connect footprint :p

2013-10-04T02:30:00 < dongs> each step is different from the previous
2013-10-04T02:30:31 <+Steffan-> details..
2013-10-04T02:32:40 < ohsix> 22 is the notable one
2013-10-04T02:32:52 < ohsix> apparently the ceo or someone high up got the boot
2013-10-04T02:36:58 < dongs> In order to become world leader in
2013-10-04T02:36:59 < dongs> PCB design, Altium needs to have
2013-10-04T02:36:59 < dongs> a dominant presence at the two
2013-10-04T02:36:59 < dongs> extreme ends of the market.
2013-10-04T02:37:01 < dongs> this is true tho
2013-10-04T02:37:17 < dongs> they need to dump the fucking FPGA simulation/C compiler shit
2013-10-04T02:37:22 < dongs> and sell just schamtic+pcb for liek $1k
2013-10-04T02:37:25 < dongs> then I'll totally buy it
2013-10-04T02:37:48 < ohsix> also a free version
2013-10-04T02:37:57 < dongs> free version = queer2queer
2013-10-04T02:38:06 < ohsix> they'll clobber all the jerks with free stuff by being awesome
2013-10-04T02:38:14 < ohsix> then they skim licenses off the top
2013-10-04T02:38:27 < dongs> i paid for full dicktrace, never regret it
2013-10-04T02:39:08 < dongs> first 4l board i made in dicktrace paid for its license just by selling one
2013-10-04T02:39:12 < dongs> so shrug
2013-10-04T02:39:35 < dongs> but i dont wanna pay 9k for altidong when i wont use 90% of the shit in it
2013-10-04T02:39:59 < dongs> fpga??? simulation??? c compiler?? C ide??? non-working gerber editor/viewer?? no thanks to all this shit
2013-10-04T02:40:05 < englishman> eevblog had a rant about free altium recently
2013-10-04T02:40:11 < ohsix> shh
2013-10-04T02:40:29 < ohsix> co simulation is cool
2013-10-04T02:40:43 < ohsix> but yea if you cant buy the part you want at any price then you're done
2013-10-04T02:41:49 < zyp> dongs, the gerber-stuff is non working?
2013-10-04T02:42:05 < zyp> I just thought I were too dumb to understand it :p
2013-10-04T02:42:17 < ohsix> it may even be a good deal if you need some or all of that stuff, but if you can't have the pcb junk for less then you're not going to be having it
2013-10-04T02:43:36 < zyp> I'm tempted to dick around with the fpga stuff, since I have it either way
2013-10-04T02:43:57 < zyp> to see how useful it is in practice
2013-10-04T02:46:04 < dongs> zyp: yeah it didnt seem very useful at all, and broke on half the gerber files I threw at it
2013-10-04T02:46:08 < dongs> so no idea
2013-10-04T02:46:19 < dongs> but it does a good job of associating itslf with .gbr .cam .etc files
2013-10-04T02:46:30 < zyp> heh, true
2013-10-04T02:46:41 < ohsix> how do you know the files aren't broke and altium isn't just a little anal about it
2013-10-04T02:46:47 < dongs> cuz i have cam350
2013-10-04T02:47:24 < ohsix> o ic
2013-10-04T02:47:26 < zyp> ohsix, in my case it was files generated by altium itself
2013-10-04T02:47:46 < zyp> it didn't break them though, it just didn't seem to be able to do much useful with them
2013-10-04T02:47:47 < ohsix> so what happened when you opened it, did altium say what was wrong or were parts just missing or what
2013-10-04T02:48:04 < zyp> but then again I didn't bother spending time dicking around with it

2013-10-04T03:03:29 < talsit> to make sure ground fill doesn't go there
2013-10-04T03:03:54 < talsit> since, you may be inserting pins all the time, you may end up lifting some soldermask
2013-10-04T03:44:01 < dongs> sounds like a fail solution to me.
2013-10-04T03:44:11 < dongs> either shut up and use tagconnect or just flash over serial bootloader

2013-10-04T05:13:53 < dongs> cool
2013-10-04T05:14:02 < dongs> at least my suppliers tell me
2013-10-04T05:14:05 <+Steffan-> maybe because they are all cheap *sses and all use the cheapest manufacturer they can find?
2013-10-04T05:14:05 < dongs> do you want the working part
2013-10-04T05:14:07 < dongs> or the cheap clone one
2013-10-04T05:14:13 < emeb_mac> yeah they just loved swapping out those parts by hand

2013-10-04T10:02:24 < Robint91> is Radiant intensity mW/sr a total enegry output of a led
2013-10-04T10:03:16 < jpa-> total output per steradian
2013-10-04T10:03:59 < Robint91> jpa-, does it depend on the Angle of half intensity ?
2013-10-04T10:04:06 < emeb_mac> so you'd need to figure out number of steradians the output pattern has
2013-10-04T10:04:47 < jpa-> Robint91: that's a pretty good question.. if there is no further information, i would assume that the given value is the intensity in the strongest point of the output pattern

2013-10-04T14:40:22 < Laurenceb> buying F429 discovery
2013-10-04T14:45:49 < trepidaciousMBR> 429 discoveries for everyone!
2013-10-04T14:46:03 < trepidaciousMBR> Now I just need to look fondly at it until ChibiOS gets ported :)
2013-10-04T14:46:13 < dongs> lol chibios.
2013-10-04T14:46:56 < talsit> trepidaciousMBR: would there be that much difference from the F405/7?
2013-10-04T14:47:25 < trepidaciousMBR> There are some changes to registers, like VOS etc. I'm not sure how much needs doing, and I'm not that familiar with the low level stuff
2013-10-04T14:47:39 < trepidaciousMBR> I think Giovanni is going to look at it though :)
2013-10-04T14:48:30 < trepidaciousMBR> AFAICT the peripherals are very similar though, just extra ones added one, plus new banks of SRAM/Flash, more DMA streams, but it looks kind of like most stuff should just work
2013-10-04T14:49:26 < dongs> does any of that stuff even work in chibidongsOS
2013-10-04T14:49:30 < dongs> i thought half of it was broken
2013-10-04T14:50:34 < qyx_> actually never had any problem with anything
2013-10-04T14:50:45 < talsit> is it pin-compatible with 407?
2013-10-04T14:50:53 < talsit> it should be, right?
2013-10-04T14:52:00 < Laurenceb> resistive touchscreen?

2013-10-04T15:08:27 < Thorn> the downside to that is postage cost, 20 euros
2013-10-04T15:08:48 <+Steffan-> Yeah, i guess that's the problem. None of the other languages show this company only text

2013-10-04T15:10:01 < Thorn> maybe they forgot to update it, I haven't headr about this kind of restrictions at farnell (and I'd expect them for russia rather than .nl if any)

2013-10-04T15:23:09 < Thorn> wat
2013-10-04T15:24:47 < dongs> . It includes the ILI9341

2013-10-04T15:24:51 < dongs> The STM32F429ZIT6 MCU controls this motion sensor through the SPI interface.

2013-10-04T16:33:20 < dongie> is there llvm target for cortex already?
2013-10-04T16:33:23 < dongie> that isn't fucking useless beta?
2013-10-04T16:33:29 < dongie> crossworks3.0 uses llvm apparentlty
2013-10-04T16:33:33 < dongie> instead of gcc/gae/whatever
2013-10-04T16:35:25 <+Steffan-> it does? Since when does llvm produce useable stuff for cortex-mX?
2013-10-04T16:35:33 < dongie> tahts what im wondering
2013-10-04T16:40:32 < Thorn> I haven't seen cortex-m mentioned in release notes for the last 2 releases or so
2013-10-04T16:41:38 < effractur> well if it does tumb2 and armv6/armv7(e) you can use it
2013-10-04T16:41:42 < Thorn> you can ask on #llvm at oftc

2013-10-04T22:57:03 < Posterdati> hi
2013-10-04T22:57:05 < Posterdati> a question
2013-10-04T22:57:19 < Posterdati> is laks usb.process() thread safe?
2013-10-04T22:58:32 < jpa-> you probably shouldn't call it from multiple threads at the same time
2013-10-04T22:59:54 < Posterdati> and that's ok, I mean: all the example I saw usb.process() is called in the same loop of usb.write(), what if I've got usb.process() executed in a task and usb.write() in another task?
2013-10-04T23:00:14 <+Steffan-> look at what it does?
2013-10-04T23:00:53 < Posterdati> I can achieve a bunch of transfer than I've got libusb transfer error (code 1)
2013-10-04T23:03:08 < karlp> sounds like an answer doens't it.
2013-10-04T23:03:15 < karlp> though, given your usual antics, who the hell knows
2013-10-04T23:04:08 < jpa-> except for rblog, there doesn't seem to be an immediate conflict between usb.write() and usb.process(), but i would still put a lock on it just to be safe..
2013-10-04T23:04:25 < Posterdati> on usb process?
2013-10-04T23:05:06 < jpa-> to serialize any access on usb
2013-10-04T23:05:28 < Posterdati> well writing to an endpoint it's done from one task only
2013-10-04T23:10:19 < Posterdati> jpa-: I was thinking that ep_ready could do that
2013-10-04T23:11:16 < jpa-> uh.. i don't think so..
2013-10-04T23:11:24 < jpa-> were you going to busy-loop on it or what?
2013-10-04T23:11:43 < Posterdati> busy loop
2013-10-04T23:11:48 < Posterdati> with timeout
2013-10-04T23:11:48 < jpa-> sounds stupid
2013-10-04T23:12:15 < jpa-> just use semaphores or any other proper RTOS syncronization method
2013-10-04T23:13:17 < Posterdati> jpa-: what will be the stragtegy? Execute read/write outside usb.process() execution?
2013-10-04T23:13:56 < jpa-> yeah
2013-10-04T23:14:16 < Posterdati> ok, let's try... Hope this will work
2013-10-04T23:14:26 < jpa-> i bet it won't
2013-10-04T23:14:34 < Posterdati> why?
2013-10-04T23:14:46 < jpa-> you still have approximately 9 bugs left in your code
2013-10-04T23:15:01 < Posterdati> lol could you tell me which please?
2013-10-04T23:15:27 < Posterdati> your third eye surely can
2013-10-04T23:15:29 < jpa-> nope
2013-10-04T23:15:39 < jpa-> it's a statistical figure :)
2013-10-04T23:15:59 < Posterdati> if they are only 9 I'm lucky
2013-10-04T23:16:16 < Posterdati> this lock/unlock bug count for 10th?
2013-10-04T23:16:40 < jpa-> well i know nearly nothing about laks nor how you are using it
2013-10-04T23:16:51 < Posterdati> lol
2013-10-04T23:17:07 < Posterdati> so thank for your hints

2013-10-05T00:43:57 <+Steffan-> sample some stm32f429 discovery or so while you're there karlp :)
2013-10-05T00:44:37 <+Steffan-> meh, maybe not so useful.

2013-10-05T00:44:57 < Laurenceb_> lolz
2013-10-05T00:45:03 < karlp> no, I really don't need one of them, and anywya, they can get tacked on to a work digikey/mouser order any time
2013-10-05T00:46:30 < Laurenceb_> <emeb> it's for your own good. why complain?
2013-10-05T00:46:34 < Laurenceb_> troll detected
2013-10-05T00:46:52 <+Steffan-> Yeah... but I dont know what you need karlp. Except for this RF stuff you talk about once in a while
2013-10-05T00:47:15 < Laurenceb_> has anyone got an stm32w  ?
2013-10-05T00:47:15 <+Steffan-> Laurenceb_, i wonder if the servers behind the nasa website etc. are actually still running
2013-10-05T00:47:20 < Laurenceb_> yeah wtf
2013-10-05T00:47:32 < Laurenceb_> why cant they just leave it running without updates
2013-10-05T00:47:45 < Laurenceb_> i think they are trying to prove a point
2013-10-05T00:48:10 <+Steffan-> it's like this christian-ish website that's closed on sunday :D
2013-10-05T00:48:26 < Laurenceb_> or all our shops in the UK
2013-10-05T00:48:37 < Laurenceb_> actually thats not 100% true anymore
2013-10-05T00:48:40 < Laurenceb_> anyways
2013-10-05T00:48:41 <+Steffan-> Yes, but this is a website.. with a message. so the server is probably still running
2013-10-05T00:48:58 < Laurenceb_> try the ip address of the old server....
2013-10-05T00:49:15 < Laurenceb_> but i dont know what it is :P
2013-10-05T00:49:47 < emeb> wait - Laurenceb_ has accused me of trolling? :)
2013-10-05T00:50:01 < Laurenceb_> trollercoaster remember
2013-10-05T00:50:13 <+Steffan-> *DrLaurenceb emeb :P
2013-10-05T00:50:22 < karlp> Steffan-: I really need more time for playing on projects :)
2013-10-05T00:50:24 < Laurenceb_> not yet
2013-10-05T00:50:34 < karlp> or for work to have new projects more applicable to this channel :)
2013-10-05T00:50:43 < Laurenceb_> needs a while for feedback

2013-10-05T03:53:48 < emeb> never to wrestle with a pig. You get dirty, and besides, the pig likes it

2013-10-05T03:55:26 < dongs> thats funny
2013-10-05T03:55:28 < dongs> i made one in diptrace
2013-10-05T03:55:30 < dongs> few weeks ago
2013-10-05T03:56:28 < emeb> diptrace is much nicer for making footprints

2013-10-05T03:58:40 < dongs> in dicktrace its fairly easy, you make 3 lines at correct pitch, then you can use group move and grid snap to space them vertically, then do teh zigzag shit again using grid snap and selecting a row at a time
2013-10-05T03:59:01 < dongs> it would be cool if it had "offset group by xx" option but gridsnap works ok for that jsut gotta change it and calculate
2013-10-05T03:59:18 < dongs> and of course realtime measure stuff where you can just set grid to 0.01 or something and nudge it until it aligns.
2013-10-05T03:59:28 < dongs> opensauce that shit, bitch
2013-10-05T03:59:29 < emeb> ya
2013-10-05T03:59:56 < emeb> this is complicated enough that I'm considering writing a script to generate the footprint
2013-10-05T04:00:11 < dongs> lolool
2013-10-05T04:00:15 < dongs> did you check djdelorie's site
2013-10-05T04:00:17 < emeb> iknowrite?
2013-10-05T04:00:19 < dongs> maybe he already wasted time making it
2013-10-05T04:00:43 < emeb> good idea. but there's another guy who's got even more fps and he doesn't have any hirose
2013-10-05T04:01:43 < dongs> which one is it, the one on xilinx evalboards?
2013-10-05T04:02:04 < emeb> similar. just a 40-pin

2013-10-05T07:14:39 < zippe> It's another stupid SoC from a company that doesn't understand SoCs
2013-10-05T07:14:52 < zippe> I mean, 359 balls and … two fucking UARTs.  Seriously; two.
2013-10-05T07:15:12 < zippe> Also, it has "DOS memory".
2013-10-05T07:15:18 < zippe> And an 8259.
2013-10-05T07:15:36 < zippe> And system management mode.
2013-10-05T07:16:39 < zippe> It even remaps Cseg to PCI so you can run PCI video card in MDA emulation mode.
2013-10-05T07:16:55 < zippe> Oh wait, MDA was B, so I guess that would be CGA mode.
2013-10-05T07:33:10 < dongs> zippe: rantin about intel x86 thing?
2013-10-05T07:33:10 < dongs> :)

2013-10-05T07:41:26 < zippe> Neat? Meh. If I wanted an SoC styled after a PX/AT, I would have downloaded something from OpenCores.
2013-10-05T07:42:12 < zippe> The funniest thing is .. that board needs 3A @ 5V, and they put the chip into a … wait for it … wristwatch development kit
2013-10-05T07:43:06 < dongs> wait what
2013-10-05T07:43:15 < dongs> 3A at 5V?
2013-10-05T07:48:02 < emeb_mac> lol
2013-10-05T07:48:06 < emeb_mac> that's intel for you
2013-10-05T07:48:38 < emeb_mac> low power for them means "draws less than 20W"
2013-10-05T07:48:49 < dongs> how the fuck can they make 32nm pentium require 3A

2013-10-05T07:49:19 < dongs> and then spent a year figuring out all teh bugs
2013-10-05T07:55:14 < GargantuaSauce> my favourite intel thing is the atoms that all advertise <8W tdp
2013-10-05T07:55:20 < GargantuaSauce> and then the northbridge draws 2-3x as much
2013-10-05T07:56:36 < dongs> http://www.fap.co.rs/fap/home%20eng.htm
2013-10-05T08:03:12 < upgrdman> whats a northbridge do?
2013-10-05T08:05:05 < gxti> it has the rest of the crap the cpu doesn't have, like IO controllers
2013-10-05T08:05:08 < GargantuaSauce> bridges the fsb to memory and peripherals
2013-10-05T08:06:03 < GargantuaSauce> (and in the current generation has been largely integrated into the cpu)
2013-10-05T08:06:34 < upgrdman> so does a cpu just so math/logic, and leave everything else to external periphs?
2013-10-05T08:07:01 < GargantuaSauce> yep
2013-10-05T08:07:03 < gxti> it varies
2013-10-05T08:07:17 < gxti> i mean an actual cpu does, yes, but x86 stuff often still has crap on the cpu
2013-10-05T08:07:35 < upgrdman> ok
2013-10-05T08:07:37 < gxti> memory controller, pcie, etc.
2013-10-05T08:07:57 < upgrdman> pcie lines go straight to cpu?

2013-10-05T09:37:54 < emeb_mac> some dude is telling me that fine pitch parts should be rotated 45deg to get even coverage on all pins.
2013-10-05T09:38:05 < dongs> uh
2013-10-05T09:38:15 < dongs> maybe his stencil printer sucks?
2013-10-05T09:38:20 < emeb_mac> heh
2013-10-05T09:38:26 < dongs> im using ghetto shit at home and i had no problems with 0.4mm pitched stuff
2013-10-05T09:38:31 < dongs> and of course production no issue at all
2013-10-05T09:38:45 < emeb_mac> he's doing an auto stenciler
2013-10-05T09:39:30 < dongs> yeah it should not be issue in production at all.
2013-10-05T09:39:42 < dongs> maybe he's fucking up mask apertures or something?

2013-10-05T10:24:19 < dongs> esp for anything that isnt giant dips.
2013-10-05T10:24:45 < dongs> i.e. its 'shrink' rules are retarded for .5mm pitch qfp
2013-10-05T10:24:53 < dongs> it makes the paste lines so thin they're unusable.
2013-10-05T10:25:04 < emeb_mac> orly?

2013-10-05T16:26:55 < Laurenceb_> wtf is that guy on

2013-10-05T16:28:22 < Laurenceb_> first day = UK, second day = Finland
2013-10-05T16:28:43 < Laurenceb_> daytime in Finland is like half way to nightime
2013-10-05T16:33:27 < qyx_> is anyone ready in russia to recover it?
2013-10-05T16:36:13 < Laurenceb_> prob not

2013-10-05T16:54:14 < qyx_> the b14 flight is also nice
2013-10-05T16:54:27 < qyx_> i wonder what do they use to charge liion from 0.8V solar panel
2013-10-05T16:55:05 < Laurenceb_> b11 was 8 days
2013-10-05T16:55:14 < Laurenceb_> ST MPPT chip
2013-10-05T16:55:28 < Laurenceb_> dongs: yeah this is the _only_ impressive ballooning stuff
2013-10-05T16:55:42 < Laurenceb_> rest is arduino strapped to balloon and camera
2013-10-05T16:55:49 < qyx_> SPV1040
2013-10-05T16:55:52 < qyx_> this one?

2013-10-05T16:57:21 < qyx_> huh
2013-10-05T16:57:40 < Laurenceb_> thats whats flying
2013-10-05T16:57:56 < qyx_> with cover i suppose
2013-10-05T16:58:10 < Laurenceb_> just shrink wrap
2013-10-05T16:58:57 < qyx_> i am surprised its working in these conditions with temp < -40C
2013-10-05T17:24:40 < karlp> heh, "Flexible baud rate clock (300 bps to 921.6 bps)
2013-10-05T17:24:50 < karlp> I presume that's missing a k.
2013-10-05T17:27:55 < qyx_> where?
2013-10-05T17:29:04 < qyx_> if you mean telemetry downlink, it is usually even slower
2013-10-05T17:30:25 < karlp> no, reading the stm32w datasheet (which is actually a combined ref manual, not a normal datasheet)
2013-10-05T17:32:06 < karlp> it's really got very little in common with the other stm32s,
2013-10-05T17:32:19 < karlp> the peripherals are totally different
2013-10-05T17:37:53 < Robint91> karlp, isn't it wiser to use a sperate tranciever?
2013-10-05T17:39:53 < karlp> maybe
2013-10-05T17:40:12 < karlp> less parts,less size, potentially less cost,
2013-10-05T17:40:19 < karlp> just depends how the combo is :)
2013-10-05T17:45:37 < Robint91> has someone tips on using the RTC on the F1 series
2013-10-05T17:45:49 < Robint91> -> get out the current time in hh:mm:ss
2013-10-05T17:46:09 < karlp> hehe, use any stm32 other than the f1 instead?
2013-10-05T17:46:30 < Robint91> karlp, I have a pcb containing the F1

2013-10-05T17:46:41 < karlp> people seem to have strong opinions on which is better, the BCD h:m:s on all other parts, or the linear seconds on the f1
2013-10-05T17:47:13 < Thorn> if it's not bcd it's not rtc
2013-10-05T17:47:22 < Thorn> just a counter
2013-10-05T17:48:51 < qyx_> rtc is just a counter

2013-10-05T17:52:38 < barthess> hm... is there RTCs with both counter and BCD?
2013-10-05T18:17:12 < Laurenceb_> not that ive seen
2013-10-05T18:17:30 < Laurenceb_> but yeah counter makes way more sense

2013-10-05T18:35:34 < Posterdati> where's zyp?
2013-10-05T18:35:41 < Posterdati> zyp: I solved!
2013-10-05T18:37:18 < Posterdati> the sad thing is that usb.process() couldn't be interrupt during packet transfer, I didn't account that in my design
2013-10-05T18:38:16 < Posterdati> maybe an interrupt driven design of your usb stack could handle this
2013-10-05T18:48:42 < Posterdati> jpa-: thanks to you too

2013-10-05T21:57:31 < karlp> more datasheet gems, "Note
2013-10-05T21:57:31 < karlp> 1: In case of running out of PCB space, pin 4 and pin 9 can be left unconnected."
2013-10-05T21:58:10 < Posterdati> karlp: I ran out money
2013-10-05T22:00:44 < Posterdati> never left 4 and 9
2013-10-05T22:04:24 < Robint91> karlp, those pins are?
2013-10-05T22:04:29 < karlp> this datasheet says that recommended bypass capacitors for some of these pins are 3.3pF.
2013-10-05T22:10:07 < karlp> Robint91: avdd and avss on a rf transceiver,
2013-10-05T22:11:45 < qyx_> wtf is that chip? stm32w?
2013-10-05T22:13:16 < karlp> no, mrf24xa, microchip's updated version of the mrf24j40
2013-10-05T22:13:31 < karlp> cheaper, smaller, less errata, better power
2013-10-05T22:13:50 < karlp> well, according to the datasheet anwway
2013-10-05T22:14:06 < karlp> too busy reading datasheets for thigns I don't have, instead of working out why my existing ones lock up
2013-10-05T22:14:48 < karlp> has this neat thing where when you are spi clocking in a command, it clocks out a status byte for you automatically,
2013-10-05T22:14:53 < karlp> instead of just clocking out 0s
2013-10-05T22:19:46 < gxti> do the blackmagicprobe users here use the uart much?
2013-10-05T22:19:56 < gxti> trying to figure out if having uart there is worth an extra isolator
2013-10-05T22:21:50 < Robint91> gxti, those silicon isolators are cheap so?
2013-10-05T22:24:39 < gxti> board area isn't free either but if i stick to the ssop ones it won't be the limiting factor

2013-10-05T22:47:12 < qyx_> hm, cheaper than similar adum parts
2013-10-05T22:48:20 < gxti> i'm somewhat worried that the price is an anomaly and will disappear just before i need them
2013-10-05T22:52:46 < karlp> no, we use ths si spi isolaters, they're just cheaper than the adum ones,

2013-10-05T23:44:36 < karlp> hehe, install wine, runs installer, demands java to continue
2013-10-05T23:44:46 < karlp> what, I have to install java in wine?!
2013-10-05T23:45:13 < Posterdati> karlp: the amd64 wine version?
2013-10-05T23:45:50 < karlp> yes, but I don't really see hwo that's relevant
2013-10-05T23:46:55 < qyx_> yep, if wine sw requires java, you have to instal windows jre
2013-10-05T23:47:20 < Posterdati> karlp: times ago the amd64 bit version didn't work
2013-10-05T23:47:41 < gxti> do you need it just to run the toolchain? last time i tried mchp on linux was before they went all edgy
2013-10-05T23:47:52 < gxti> worked fine in wine

2013-10-06T13:33:16 < Posterdati> the handle_in is performed in a task with tick frequency of 800 Hz
2013-10-06T13:34:10 < zyp> uh, ok

2013-10-07T02:13:36 < zyp> the libusb stuff you dicked with, that was raw.
2013-10-07T02:13:46 <+Steffan-> That was not Posterdati.
2013-10-07T02:15:50 < Posterdati> zyp: is bulk transfer raw?
2013-10-07T02:16:02 < zyp> …
2013-10-07T02:16:27 < zyp> raw in this context means «vendor specific», i.e. not a predefined class.
2013-10-07T02:16:40 < Posterdati> well I'm using cdc
2013-10-07T02:16:44 < Posterdati> is that a class?
2013-10-07T02:17:06 < zyp> when you use bulk transport directly from libusb without any class stuff in between, that can be described as talking raw usb
2013-10-07T02:17:39 < Posterdati> ok
2013-10-07T02:18:04 < zyp> cdc is a class, yes, which means you get to talk to class specific drivers
2013-10-07T02:18:24 < Posterdati> cdc coded in the device
2013-10-07T02:18:30 < zyp> so instead of talking to a usb device, you can talk to a serial port, which then the cdc driver translates to usb for you
2013-10-07T02:18:51 < Posterdati> yes I read that part
2013-10-07T02:19:31 < Posterdati> well my application could be similar to your hid example about the game pad
2013-10-07T02:20:10 < Posterdati> but I CDC could cope too
2013-10-07T02:20:27 < zyp> anyway, good to hear you found something that works
2013-10-07T02:20:44 < Posterdati> yes and it was truly simple at last
2013-10-07T02:20:55 < Posterdati> I didn't mess with usb code
2013-10-07T02:20:57 < dongs> In order to ensure the stability of board performance, our PCB manufacture craft for the heavy gold board, power supply IC all adopt imported regulator IC, the wiring lines to walk is go in strict accordance with the specification, in terms of answering the GND, anti-jamming are under a lot of kung fu, the plate is SMT patch, neat and easy appearance.
2013-10-07T02:21:02 < dongs> holy fucking shit.
2013-10-07T02:21:30 < Posterdati> zyp: only that problem with interrupt and usb.process()
2013-10-07T02:21:54 < zyp> dongs, by the way, how did it go with the F3 quadrotor boards you were making?
2013-10-07T02:22:08 < dongs> zyp: they're made. havente done anything else wiht it.
2013-10-07T02:22:21 < dongs> oh, there's some working firmware with proper calculations (not by me).
2013-10-07T02:22:28 < dongs> appears to work.
2013-10-07T02:22:48 < Posterdati> zyp: usb.process() is not thread safe :)
2013-10-07T02:22:55 < zyp> I was thinking about porting my shit to it, I'm not sure the sensors on my board is sane
2013-10-07T02:23:08 < zyp> it had native usb?
2013-10-07T02:23:12 < dongs> ya
2013-10-07T02:23:13 < zyp> and which sensors?
2013-10-07T02:23:35 < dongs> mpu6k, hmc5983, 5611 pressure
2013-10-07T02:23:42 < dongs> all on spi
2013-10-07T02:23:51 < zyp> ah, nice
2013-10-07T02:24:07 < Posterdati> mpu6k the stupid chip with do sensors fusion only if you buy the license?
2013-10-07T02:24:27 < dongs> yes, because  you can't do it yourself with raw sensor readings at all.
2013-10-07T02:24:31 < dongs> the license prevents you from doing that.
2013-10-07T02:25:32 < zyp> I'll probably buy a couple off you some time then, maybe next time I'm getting other stuff from you :p
2013-10-07T02:25:33 < Posterdati> did you buy it?
2013-10-07T02:26:51 < dongs> zyp: sure.
2013-10-07T02:29:39 < Posterdati> dongs: what do you sell^
2013-10-07T02:29:40 < Posterdati> ?
2013-10-07T02:30:02 <+dekar_> Posterdati, why is HID nonsense? It works fine for me :)
2013-10-07T02:30:36 < zyp> dekar_, because he had no idea about what he was doing
2013-10-07T02:30:40 < Posterdati> dekar_: sure it works, but I do not need for my project, cdc is ok too
2013-10-07T02:30:57 < dongs> Posterdati: everything
2013-10-07T02:31:07 < zyp> dekar_, and also because hid is not suited for the fast streaming of data that he wanted to do
2013-10-07T02:31:33 < Posterdati> dongs: I hope you don't sell cars too
2013-10-07T02:31:41 <+dekar_> that's true, though CDC usually comes with manual driver installations :/
2013-10-07T02:31:52 < Posterdati> zyp: speed(hid) < speed(cdc)?
2013-10-07T02:32:04 < zyp> Posterdati, yes
2013-10-07T02:32:37 < Posterdati> zyp: speed(hid) < 204 kbit/s
2013-10-07T02:32:38 <+dekar_> HID only does 64bytes/ms
2013-10-07T02:32:47 < zyp> yep
2013-10-07T02:33:08 < zyp> because hid is using interrupt transport, which is limited to one packet per frame
2013-10-07T02:33:18 < zyp> so max 64 kB/s
2013-10-07T02:33:49 <+dekar_> Yet when updating my STM32's firmware via HID, the actual bottleneck is the flash erase speed.
2013-10-07T02:34:34 < zyp> you don't need insane speeds for bootloader stuff ;)
2013-10-07T02:37:36 < Posterdati> anyway it works now
2013-10-07T02:38:19 < zyp> dongs, by the way, I looked through some baseflightplus code earlier today, what's up with the 500/200/100Hz stuff?
2013-10-07T02:39:32 < Posterdati> zyp: are you going to create an IRQ base usb driver?
2013-10-07T02:40:08 < zyp> Posterdati, later
2013-10-07T02:40:41 < Posterdati> anyway stm32f107 has got only one IRQ for OTG_FS
2013-10-07T02:40:49 < zyp> of course it does
2013-10-07T02:41:11 < zyp> and it's not sane to do all the usb processing in the ISR
2013-10-07T02:41:20 < Posterdati> yes
2013-10-07T02:41:23 < Posterdati> too long
2013-10-07T02:41:27 < Posterdati> but
2013-10-07T02:41:44 < Posterdati> why interrupting usb.process() causes usb to go in error?
2013-10-07T02:42:20 < zyp> the way I'm going to do it is to have the usb processing in it's own thread, then that thread will sleep when it doesn't have anything to do, then the ISR will wake up that thread again when it has something to do
2013-10-07T02:42:37 < zyp> but before I can do that I need to put more work into my thread scheduler
2013-10-07T02:42:53 < Posterdati> ok
2013-10-07T02:44:01 < Posterdati> anyway I could not miss sensors reading
2013-10-07T02:44:32 < zyp> interrupting usb.process() shouldn't cause any problems, and ep_ready() and write() should be safe to call from other threads
2013-10-07T02:44:50 < Posterdati> mmmh it seems no to be the case
2013-10-07T02:45:12 < Posterdati> I let usb.process() in a thread
2013-10-07T02:45:17 < Posterdati> and it won't work
2013-10-07T02:45:20 < zyp> I have projects where I do it.
2013-10-07T02:45:38 < Posterdati> ok
2013-10-07T02:45:59 < zyp> however, keep in mind that the callbacks are called from usb.process(), so if your callbacks aren't threadsafe you might get issues
2013-10-07T02:46:03 < zyp> but that's not my responsibility
2013-10-07T02:46:32 < Posterdati> which callbacks? the CDC class handle_in/out?
2013-10-07T02:47:11 < zyp> yes
2013-10-07T02:47:30 < Posterdati> well I don't use out so much, but only _in
2013-10-07T02:47:42 < zyp> well, that's not a callback
2013-10-07T02:48:04 < Posterdati> I was thinking that usb.process() could live in a thread
2013-10-07T02:48:08 < zyp> I think the handle_in-name is a bit dumb, because I use handle_*-stuff for callbacks :p
2013-10-07T02:48:11 < zyp> sure
2013-10-07T02:48:47 < Posterdati> and that it could be interrupted from other tasks and IRQ
2013-10-07T02:48:51 < zyp> http://cgit.jvnv.net/suzumebachi/tree/main.cpp#n257 <- that's what it does here

2013-10-07T02:49:57 < zyp> yep
2013-10-07T02:50:11 < Posterdati> ah that way should work
2013-10-07T02:50:40 < Posterdati> because you are sure to pass control to other code as soon as you execute usb.process
2013-10-07T02:50:52 < zyp> fair point
2013-10-07T02:51:03 < Posterdati> I haven't got such scheduling scheme
2013-10-07T02:51:22 < Posterdati> my scheduler it's a simple round robin task switching scheme
2013-10-07T02:51:29 < zyp> so is mine
2013-10-07T02:51:38 < Posterdati> yes but not cooperative
2013-10-07T02:52:03 < Posterdati> it switches from task to the next at ixed time
2013-10-07T02:52:06 < zyp> I have no notion of whether threads are ready or not, so they all just yield whenever they don't have anything to do
2013-10-07T02:52:16 < Posterdati> ah ok
2013-10-07T02:52:22 < Posterdati> it's a scheduling strategy
2013-10-07T02:52:57 < Posterdati> I change task everytime I execute PendSV IRQ
2013-10-07T02:53:22 < zyp> I did some work on improving the scheduler while I was bored on a flight this summer, but I haven't finished it yet
2013-10-07T02:53:33 < Posterdati> good
2013-10-07T02:53:39 < zyp> I didn't bring any hardware with me, so the code has only been tested in qemu so far :p
2013-10-07T02:53:54 < Posterdati> could be a scheduler be taken from linux stuff?
2013-10-07T02:54:04 < zyp> heh
2013-10-07T02:54:05 < Posterdati> or is it too big?
2013-10-07T02:54:12 < zyp> no idea really
2013-10-07T02:54:15 < zyp> sounds pointless
2013-10-07T02:55:10 < Posterdati> well I think that a good RTOS should have a robust signals handling facility

2013-10-07T03:04:58 < Posterdati> ok

2013-10-07T03:06:24 < zyp> and I would certainly consider accepting good patches, but on the other hand this is a toy project that's kind of a sandbox for fun stuff I want to do, and I kinda want to keep it that way
2013-10-07T03:07:07 < Posterdati> zyp: well if your work is done like the usb one it should be more than a toy project

2013-10-07T06:01:48 < dongs> <Mrgoose2> Any of you do any arduino work?
2013-10-07T06:27:49 < zippe> Does anyone do arduino "work"?

2013-10-07T06:28:36 < zippe> dongs: the GPIO situation is hysterical
2013-10-07T06:28:57 < dongs> zippe: you mean on i2c expander?
2013-10-07T06:29:02 < zippe> Yes
2013-10-07T06:29:04 < dongs> yeah, hysterical to the max
2013-10-07T06:29:22 < dongs> doesnt the chip have some normal fucking gpio out of 300+ balls?:)
2013-10-07T06:29:23 < zippe> I asked some folks that would know… it seems like the chip is a short bus special all around
2013-10-07T06:29:30 < zippe> It does
2013-10-07T06:29:36 < zippe> But they are 1.8V GPIOs
2013-10-07T06:29:40 < dongs> oh of course.
2013-10-07T06:29:45 < dongs> NOT COMPATIVBLE WIHT TARDUINO
2013-10-07T06:29:52 < zippe> And I think not even 3v3 tolerant
2013-10-07T06:30:03 < dongs> wouldnt surprise me if they werent.
2013-10-07T06:30:13 < dongs> but still, they're already level shifting teh shit..
2013-10-07T06:30:24 < dongs> even off i2c expander..
2013-10-07T06:30:28 < zippe> dongs: yeah, but Arduino GPIOs are current sources
2013-10-07T06:30:40 < zippe> and they don't have enough extra GPIOs for per-pin direction controls
2013-10-07T06:30:51 < zippe> So they would have to use the auto-sensing GPIO level shifters
2013-10-07T06:30:56 < zippe> which can't source current worth a damn
2013-10-07T06:31:06 < dongs> ah
2013-10-07T06:31:15 < dongs> shittay.
2013-10-07T06:31:21 < dongs> oh well, its tarduino after all
2013-10-07T06:31:31 < zippe> Kinda sad because the CPU core itself is actually kinda interesting
2013-10-07T06:31:34 < dongs> but yea h,w hen i saw i2c expander on block diagram, i was like...
2013-10-07T06:31:55 < zippe> But the chip is bad and the board is as far again beyond
2013-10-07T06:32:10 < dongs> i guess they're hoping that since tarduino gpio takes like 300 avr cycles to toggle, they could get away with sticking it on i2c
2013-10-07T06:32:25 < dongs> "ITS SLOW IF YOU USE ARDUINO LIBS, SO NOONE WILL NOTICE"
2013-10-07T06:33:08 < dongs> zippe, thanks for a good laugh

2013-10-07T16:41:28 < Robint91> or is it going to send each byte/n*bytes over the interface
2013-10-07T16:42:34 < dongs> rx/tx are bulk pipes.
2013-10-07T16:43:47 < Robint91> dongs, that means...
2013-10-07T16:45:00 < dongs> that means they can be longer than 64bytes which would be control pipe.

2013-10-07T16:54:23 < zyp> control and bulk transfers larger than max packet size for the endpoint will be broken down into multiple packets
2013-10-07T16:54:37 < zyp> for FS USB this is 64B

2013-10-07T16:55:35 < zyp> for CDC ACM it doesn't matter either way, because it emulates a byte stream
2013-10-07T16:56:13 < zyp> two packets of 4 bytes or one packet of 8 bytes is the same, it's all just a stream of bytes and frame boundaries have no meaning
2013-10-07T16:57:41 < zyp> but for other classes like mass storage the frame boundary is important, because it's used to distinguish between commands
2013-10-07T16:58:29 < zyp> each command consists of three transfers; command, data and status, and the data-transfer may be larger than 64 bytes, in which case it would consist of multiple packets
2013-10-07T17:00:01 < zyp> http://bin.jvnv.net/f/5pyzn.png <- like this
2013-10-07T17:00:40 < dongs> nom nom
2013-10-07T17:00:41 < zyp> first 31 bytes for the command itself, then 16384B of data split into 64B packets
2013-10-07T17:00:44 < dongs> i knew i was pulling shit out of my ass
2013-10-07T17:01:08 < dongs> since i ever cared about bulk pipes on 2.0hs
2013-10-07T17:01:45 < zyp> the only thing that's different about HS is the max packet size, which is 512 instead of 64
2013-10-07T17:01:59 < zyp> transfers larger than 512B will still be split into 512B packets

2013-10-07T17:07:23 < trepidaciousMBR> God bless them for making mass storage complicated, would be cool if you just sort of, poked bytes at it and it worked :)
2013-10-07T17:07:43 < trepidaciousMBR> (Forgive the technical terms there :)
2013-10-07T17:08:07 < zyp> mass storage is pretty easy, it's just a thin wrapper for transporting scsi commands
2013-10-07T17:08:14 < zyp> it's the scsi part that's tricky :p
2013-10-07T17:09:29 < dongs> http://i.imgur.com/HhCIxlU.jpg lol.
2013-10-07T17:09:47 < Robint91> zyp, what class should I use when I want to have nice frame boundaries?
2013-10-07T17:10:52 < zyp> for what?
2013-10-07T17:12:04 < zyp> you don't need to use a class for it, plain bulk would give you that
2013-10-07T17:12:04 < zyp> the same way that classes using bulk get it
2013-10-07T17:12:40 < Robint91> zyp, mhh
2013-10-07T17:13:00 < zyp> the mechanism is as simple as this: a packet smaller than MPS terminates a transfer, while an MPS-sized packet means that another packet will follow
2013-10-07T17:13:40 < zyp> so if you want to transfer say 96B on a 64B endpoint, you send it as one transfer of 64B and one transfer of 32B
2013-10-07T17:14:04 < Robint91> zyp, yeah, I want something that behaves like hid reports
2013-10-07T17:14:07 < zyp> if your frame size is divisible by the MPS, you terminate it with a zero-length packet
2013-10-07T17:14:21 < zyp> so a 128B frame gets sent as 64,64,0
2013-10-07T17:15:11 < zyp> hid reports are sent over interrupt endpoints, which can't span multiple packets
2013-10-07T17:15:29 < zyp> which means that a hid report on FS USB can't be larger than 64B
2013-10-07T17:15:38 < Robint91> zyp, I don't want multiple packets
2013-10-07T17:15:48 < Robint91> zyp, but large size
2013-10-07T17:15:50 < Robint91> so bulk
2013-10-07T17:17:11 < zyp> bulk endpoints on FS USB aren't allowed to have a MPS different from 64B either

2013-10-07T17:18:27 < zyp> either way, your application shouldn't need to worry about it, splitting and reassembling transfers should be handled by the stacks

2013-10-07T18:13:42 < Luggi09> and do you think it's any good
2013-10-07T18:15:17 < emeb_mac> seen it. nice looking board, lots of goodies. seems too expensive. iPhone integration - meh.
2013-10-07T18:16:02 < Luggi09> yeah the price is a bit hefty, apparently they are getting some of those at my university
2013-10-07T18:18:54 <+Steffan-> It'll be a PITA ya? :P
2013-10-07T18:19:14 < Luggi09> dunno, the board seems pretty nice
2013-10-07T18:19:43 < Luggi09> I'm just wondering how good the development stuff for it will be

2013-10-07T18:39:55 < cehteh> pebble watch and oculus rift started as kickstarter .. that are the only successful things come to mind

2013-10-08T01:46:22 <+Steffan-> ~$50
2013-10-08T01:46:33 < emeb> Oh, I don't doubt that it's more expensive in EU.
2013-10-08T01:46:48 < emeb> Just that I was hearing rumors of freebies and I haven't seen any materialize.
2013-10-08T01:47:36 <+Steffan-> Actually, that's just 'special price' for zwitserland, in dutchland it's about $42 as well
2013-10-08T01:48:04 <+Steffan-> I always thought farnell just did some currency stuff, but that does not seem to be the case ...
2013-10-08T01:48:44 <+Steffan-> ST did show some sample button on the stm32f429i-disco page, for americans.

2013-10-08T06:51:12 < dongs> hm
2013-10-08T06:51:18 < dongs> need cheap programmable attenuator < 1GHz
2013-10-08T06:51:40 < dongs> something like -50 ~ -10dBm would be nice
2013-10-08T06:52:02 < GargantuaSauce> two antennas and a measuring tape
2013-10-08T06:52:14 < dongs> ha ha.
2013-10-08T07:23:56 < mog> hi i am just getting started with stm32 development.  is there something that can show me how to get my printfs into gdb or openocd.  i know i need to setup a semi hosted mode i just have never done it before
2013-10-08T07:24:12 < dongs> the problem is because youre using openocd + gdb
2013-10-08T07:25:04 < mog> ?
2013-10-08T07:26:28 < mog> im seeing things that hint at it but nothing with config or function to wrap printf in
2013-10-08T07:32:17 < dongs> i generally find printf to debugger to be extremely useless.
2013-10-08T07:32:27 < dongs> because instead you can just add watch variables and watch ram contents while stuff runs...
2013-10-08T07:37:47 < emeb_mac> dongs: for that attenuator - is that for on a board or as connectorized test equipment?
2013-10-08T07:38:21 < dongs> on board
2013-10-08T07:38:27 < dongs> i think i saw some stuff dektec used
2013-10-08T07:38:34 < dongs> but it was eol or something
2013-10-08T07:38:38 < emeb_mac> hittite makes a lot of stuff like that
2013-10-08T07:39:03 < emeb_mac> but it's almost all with low-speed parallel bit digital inputs for the control

2013-10-08T07:40:19 < dongs> you mean you set bits to enable attenuation steps?
2013-10-08T07:41:03 < emeb_mac> yep
2013-10-08T07:41:15 < emeb_mac> lo-tek
2013-10-08T07:41:27 < dongs> MCL31R5 is i think attenuator dicktek used on this old card
2013-10-08T07:41:32 < dongs> but all i can find now is chink sites w/it
2013-10-08T07:41:54 < emeb_mac> eol fer sure

2013-10-08T07:51:16 < emeb_mac> low enough to pass the comm regs
2013-10-08T07:51:53 < emeb_mac> hence the attenuator...
2013-10-08T07:52:18 < dongs> and programmable for when I dont care.
2013-10-08T07:52:31 < emeb_mac> yup

2013-10-08T07:55:44 < GargantuaSauce> I'd recommend just using another uart with a usb uart bridge
2013-10-08T07:55:52 < dongs> heh
2013-10-08T07:56:04 < mog> GargantuaSauce, i think ill just dump the memory then
2013-10-08T07:56:12 < GargantuaSauce> some projects also use the usb peripheral that way
2013-10-08T07:56:14 < mog> more boxes just means more setup
2013-10-08T07:56:30 < mog> ya eventually ill be using usb as a serial device

2013-10-08T08:03:40 < dongs> shh. you're ruining my dickstarter idea

2013-10-08T11:05:55 < Robint91> zyp, I want to start easy
2013-10-08T11:06:19 < Robint91> create a device with a bulk in and out endpoint
2013-10-08T11:06:30 < Robint91> can communicate with that
2013-10-08T11:07:32 < zyp> ok
2013-10-08T11:07:46 < Robint91> zyp, any tips on the libusb part
2013-10-08T11:11:12 < zyp> the libusb api is pretty simple
2013-10-08T11:11:35 < Robint91> zyp, I guess the device side is also simple
2013-10-08T11:11:38 < zyp> make sure you use libusb-1.0
2013-10-08T11:11:42 < Robint91> so special descriptors
2013-10-08T11:11:53 < Robint91> yeah, libusb-1.0
2013-10-08T11:12:04 < Robint91> does that on windows use winusb?
2013-10-08T11:12:09 < Robint91> or something else
2013-10-08T11:12:13 < zyp> yeah, you just make a vendor specific interface, and add the endpoints you need
2013-10-08T11:12:19 < zyp> yes, it can use winusb
2013-10-08T11:12:35 < zyp> it supports multiple backends, but winusb is what I've used
2013-10-08T11:13:03 < zyp> so on windows you have to make sure winusb gets bound to the device
2013-10-08T11:13:24 < Robint91> so write a inf file
2013-10-08T11:13:30 < zyp> yes
2013-10-08T11:13:39 < zyp> or use the zadig tool that would do it for you

2013-10-08T11:16:08 < zyp> but I haven't tried it myself
2013-10-08T11:16:36 < zyp> it's not too interesting when much of the world is still using windows 7

2013-10-08T11:51:53 < GargantuaSauce> i dislike their HAL right off the bat but stripping that out will sure be easier than wrestling with a custom newlib to build lua against
2013-10-08T11:53:46 < dongs> say i wanted to switch IF output from 2 tuners into single demod
2013-10-08T11:53:49 < dongs> do I just use some analog switch?
2013-10-08T11:55:19 < dongs> im guessing: yes
2013-10-08T11:55:20 < GargantuaSauce> AD has some fancy ones for rf i do believe
2013-10-08T11:56:24 < dongs> hm yeah but IF is low anyway
2013-10-08T11:56:30 < dongs> like zeroIF or lowIF around 4-5MHz
2013-10-08T11:56:37 < dongs> so i think just any random analog shit will work
2013-10-08T11:56:51 < GargantuaSauce> oh in that case yeah
2013-10-08T12:00:07 < dongs> heh those RF switches have almost s ame part numbers as their regular analog shit
2013-10-08T12:00:14 < dongs> ADG9xx instead of ADG8xx
2013-10-08T12:00:49 < dongs> ive seen a regular switch used for hooking up SD-SDI to either transmitter or receiver, and thats 270MHz shit

2013-10-08T12:07:55 < GargantuaSauce> jeez, and i thought i was pushing it using a 4052 to switch between clocks up to 10mhz
2013-10-08T12:11:20 < jpa-> nasty thing about switching clocks is that in theory, a single corrupted clock pulse could place the rest of the logic in an undefined state
2013-10-08T12:11:41 < jpa-> not so much a problem when switching RF that is full of noise anyway :)
2013-10-08T12:12:12 < GargantuaSauce> i assure you that's the least of the problems in my shitty OISC design

2013-10-08T18:40:16 < trepidaciousMBR> From the errata, looks like they fixed the DCMI DMA thing from the 407
2013-10-08T18:41:20 < trepidaciousMBR> Also revision A had no over drive, I think that translates to it not actually working at 180MHz, just 168MHz, sounds like the revision A was just a 407 with a list of errata stating that all the new stuff didn't work :)
2013-10-08T18:41:59 < emeb_mac> lol
2013-10-08T18:43:16 < jpa-> i wonder if rev A was the first silicon they made for that chip.. because otherwise the bugs are way too many :)

2013-10-08T19:29:21 < zyp> you need to set a different LMA and VMA
2013-10-08T19:29:33 < zyp> just like the .data section
2013-10-08T19:29:57 < zyp> so it'll still be stored in flash, but then expected to be copied into ram

2013-10-08T19:31:48 < zyp> also correct
2013-10-08T19:31:54 < gxti> might be easier just to stuff it into the existing data output section
2013-10-08T19:32:06 < zyp> nah, then you'll get complaints about flag violations
2013-10-08T19:32:17 < zyp> since .data is not executable
2013-10-08T19:32:20 < trepidaciousMBR> Where does the data copy happen?
2013-10-08T19:32:24 < zyp> startup code
2013-10-08T19:32:47 < gxti> in that case, put it right after .data and move the 'end of data' symbols to after the new thing
2013-10-08T19:33:47 < trepidaciousMBR> This is in ChibiOS, I wonder if there is some example of this somewhere...
2013-10-08T19:34:05 < gxti> what i just suggested won't require any additional code
2013-10-08T19:35:23 < jpa-> yeah, put it wherever .data now goes
2013-10-08T19:35:58 < gxti> make a new section after the .data one, put your stuff there, and move the _edata symbol to the end of the new one
2013-10-08T19:36:14 < jpa-> gxti: does it matter whether it is a new section or the same one?
2013-10-08T19:36:34 < jpa-> i would just add it after the *(.data.*)
2013-10-08T19:36:38 < gxti> jpa-: zyp seems to think it would cause an error to mix data and text
2013-10-08T19:36:51 < gxti> i doubt it but i'm too lazy to try and i really don't know :p
2013-10-08T19:36:53 < jpa-> ah.. yeah.. still that
2013-10-08T19:37:10 < jpa-> not sure if it matter here but maybe
2013-10-08T19:37:26 < trepidaciousMBR> I'll give that a go...
2013-10-08T19:37:31 < jpa-> my chibios-provided ld script seems to already have ".ramtext" going into .data
2013-10-08T19:38:11 < trepidaciousMBR> ooh
2013-10-08T19:38:56 < trepidaciousMBR> So how do I get these functions in .ramtext? Attributes, or can I put a whole .o in there?
2013-10-08T19:39:20 < gxti> attribute to use .ramtext, or you can put the .o in the ldscript
2013-10-08T19:41:43 < gxti> or if you're using -ffunction-sections each function is its own named section so you can call them out in the ldscript that way
2013-10-08T19:42:02 < gxti> with chibios makefiles USE_LINK_GC=yes does that
2013-10-08T19:42:26 < trepidaciousMBR> sounds good, I just need to work out how to actually do that... ;)

2013-10-08T19:44:45 -!- _BJFreeman is now known as BJfreeman
2013-10-08T19:45:14 < gxti> eh that's annoying, .text is one of the first sections in chibios ldscript which means doing it by matching sections or files doesn't work (.text already ate them)
2013-10-08T19:45:32 < gxti> so laziest solution is to use an attribute unless you have more than a few things you want to move
2013-10-08T19:48:00 < trepidaciousMBR> Hm, might not be too bad, but there are a few functions to move, basically a few of my functions plus everything they use in the ST periph library to write flash
2013-10-08T19:48:35 < trepidaciousMBR> Hopefully if I can get them in RAM and shut down the OS first, I can overwrite my firmware in flash, without trying to run the code I'm overwriting :)
2013-10-08T19:48:41 < trepidaciousMBR> There may well be a better way to do this...
2013-10-08T19:49:37 < jpa-> are you trying to get it bricked? :)
2013-10-08T19:49:51 < jpa-> why not just have a bootloader in a separate flash block?
2013-10-08T19:53:43 < trepidaciousMBR> :)
2013-10-08T19:54:22 < trepidaciousMBR> I do, just looking at how to flash from SDRAM on a 427. Currently on a 407 with PSRAM I reset to the bootloader and that does the flashing
2013-10-08T19:54:53 < trepidaciousMBR> I was wondering whether it would be possible to make the user firmware overwrite itself
2013-10-08T19:55:45 < jpa-> yeah.. definitely it is, it's just stupid to do so :D
2013-10-08T19:56:04 < zyp> self-overwriting bootloader is a nice recipe for a brickable device
2013-10-08T19:56:36 < trepidaciousMBR> Ah no, this wouldn't be that bad - the user firmware can overwrite itself, if it fails it will fall back to the bootloader and you need to use USB to flash
2013-10-08T19:56:55 < trepidaciousMBR> the user firmware can handle a network update, the bootloader can't
2013-10-08T19:57:07 < zyp> so you're putting two bootloaders in the device?
2013-10-08T19:57:50 < trepidaciousMBR> Nope, a bootloader that can update the user firmware using a USB drive, and a user firmware that can update using network
2013-10-08T19:58:00 < trepidaciousMBR> Nothing can update the bootloader (except SWD)
2013-10-08T19:58:23 < zyp> except that the updating-part of the user firmware is a second bootloader

2013-10-08T19:59:26 < gxti> is there any extra storage that is always present?
2013-10-08T19:59:29 < gxti> like the usb drive
2013-10-08T19:59:38 < zyp> say, is it just my definition of «bootloader» that is weird here?
2013-10-08T19:59:46 < zyp> because what you describe sounds like a bootloader to me
2013-10-08T19:59:53 < gxti> technically it's not a BOOTloader zyp because it runs anytime it pleases (sarcasm)
2013-10-08T20:00:00 < trepidaciousMBR> Heh
2013-10-08T20:00:03 < zyp> gxti, no, it doesn't
2013-10-08T20:00:36 < zyp> it can't run when other parts of the system is in use, since it overwrites those other parts of the system
2013-10-08T20:00:38 < trepidaciousMBR> I'll go wiki bootloader :) To me it's something that runs on boot, and then loads a "user" firmware
2013-10-08T20:01:11 < zyp> so it has to be a separate piece of code, that you switch to when you want to use it
2013-10-08T20:01:45 < gxti> trepidaciousMBR: are you copying from the network to temporary storage, or directly to flash?
2013-10-08T20:02:19 < gxti> anyway if you have enough RAM to fit the whole program then you also have enough flash
2013-10-08T20:02:36 < gxti> i can fit a chibios+lwip bootloader in 24K and i didn't even try very hard
2013-10-08T20:02:48 < zyp> trepidaciousMBR, to me it's something that loads a software package into executable memory, which in this case is xip flash
2013-10-08T20:04:01 < trepidaciousMBR> The update copies from network to PSRAM, then resets to the bootloader that copies to user flash
2013-10-08T20:04:18 < trepidaciousMBR> with SDRAM I'm not sure I can rely on it retaining contents when I reset, but I could be wrong
2013-10-08T20:04:36 < zyp> I wouldn't
2013-10-08T20:05:16 < zyp> doing it like that sounds like a bad idea either way
2013-10-08T20:05:16 < gxti> you really don't want a user to be able to "brick" their device remotely, regardless of whether there's a fallback
2013-10-08T20:05:28 < gxti> copying into volatile memory is one such bad idea
2013-10-08T20:05:41 < gxti> better than flashing directly from the network, but still a bad idea.
2013-10-08T20:06:19 < trepidaciousMBR> Unless you have enough space for two copies of firmware in flash, you can't avoid it - as soon as you erase flash, you need to finish or you are "bricked" - not really bricked, but falling back to bootloader
2013-10-08T20:06:34 < gxti> if board space is cheap you can throw a spi flash on
2013-10-08T20:06:44 < gxti> or require usb be connected and  it spools the firmware tehre
2013-10-08T20:06:50 < trepidaciousMBR> In that situation, having it in PSRAM is not making anything any worse - anything that stops PSRAM working will also stop the flashing process anyway
2013-10-08T20:06:53 < gxti> since you said a usb drive was the backup
2013-10-08T20:07:15 < zyp> the actual writing to flash-part is pretty simple, so after you have received the firmware image, you can just disable interrupts and run a self-contained function that does that
2013-10-08T20:07:18 < trepidaciousMBR> Nope, there is a bootloader in flash that will accept an update from a USB drive, which is a little bit of a pain but definitely not bricked
2013-10-08T20:07:25 < gxti> psram is volatile. if the board loses power while flashing it's "bricked". if you use nonvolatile storage it can resume copying on powerup.
2013-10-08T20:07:42 < zyp> you can even put that function in the bootloader you already have and just jump to it
2013-10-08T20:07:53 < gxti> bricked is relative to the user, not an absolute thing. if they start an ugprade remotely and it breaks in such a way that they can't fix it remotely, that's bricked.
2013-10-08T20:07:55 < zyp> that way you don't have to load it into memory
2013-10-08T20:08:03 < trepidaciousMBR> gxti: Ah you mean the bootloader, yup that would be great but I don;t have anywhere non volatile to put it
2013-10-08T20:08:46 < trepidaciousMBR> Yup, if I added an additional SPI flash as big as the MCU flash that would sort it all out, not sure I have the space or budget but I should check
2013-10-08T20:09:26 < zyp> gxti, still doesn't solve the problem with loading an invalid image
2013-10-08T20:10:04 < gxti> it's easy enough to check that it's not corrupt before flashing. obviously if you ship a busted image they're fucked, but that's not nearly so bad as bricking if the copy is interrupted.
2013-10-08T20:10:06 < trepidaciousMBR> I checksum
2013-10-08T20:10:47 < gxti> trepidaciousMBR: anyway, like i said you can do a network loader in 24K or less, so consider that too
2013-10-08T20:12:21 < trepidaciousMBR> If I ship a firmware that is checksummed but breaks stuff, you have to use USB to recover, but that's not too bad
2013-10-08T20:12:48 < trepidaciousMBR> Yup I could also add networking to the bootloader, I wanted to keep it simple, but I guess it's not too much more
2013-10-08T20:13:34 < gxti> i haven't finished porting my network loader to coos but when i do maybe i'll publish it as a separate thing
2013-10-08T20:13:55 < trepidaciousMBR> I'm tempted to just say it has to be updated via USB, it shouldn't happen often and they need physical access to the device to use it anyway
2013-10-08T20:16:40 < trepidaciousMBR> Hm, small cheap 16MBit SPI flash, that would indeed mean that if a flash update started, it would definitely finish as long as it can eventually stay powered long enough :)
2013-10-08T20:17:20 < gxti> how big is the flash on your part(s)?

2013-10-08T20:19:57 < trepidaciousMBR> gxti: There's already PC software to use it, so it's part of that
2013-10-08T20:20:18 < trepidaciousMBR> HTTP to send the image to PSRAM, then it checksums it and if valid, software reset to the bootloader to flash it
2013-10-08T20:21:16 < trepidaciousMBR> with SPI flash I would just write to that instead of PSRAM, and I guess bootloader can just try to flash it until it succeeds and then marks it as "used" int he spi flash
2013-10-08T20:21:58 < gxti> you can also have room for two images on the spi flash, and if one fails to boot go back to the old one
2013-10-08T20:23:34 < trepidaciousMBR> Yup, I did that on a previous device that had plenty of flash
2013-10-08T20:23:37 < gxti> also if there aren't significant boot time constraints, instead of a flag indicating whether to load from spi, just always compare the active spi image against internal flash
2013-10-08T20:23:58 < trepidaciousMBR> Yeah that's true, probably wouldn't take all that long
2013-10-08T20:25:18 < trepidaciousMBR> The first approach I took was to jump to the bootloader to perform flashing, rather than resetting, I had trouble getting that to work. Seems like it should work though.
2013-10-08T20:26:41 < kevineng963> I have a question regard the DMA and SPI TX as a slave.  I setup my SPI TX to use DMA as a circular buffer, I set an interrupt on TX completion and at that time I update the first byte of the TX data which is a frame counter.  However, it looks like the DMA already shifts the first byte of data into the TX register so that byte is already one frame behing.
2013-10-08T20:26:55 < kevineng963> Here is the code for setup and interrupt http://pastebin.com/BmRnRqS8
2013-10-08T20:27:10 < kevineng963> any idea of how to go about solving this issue?
2013-10-08T20:27:40 < jpa-> kevineng963: why would you update the data in the interrupt?
2013-10-08T20:28:07 < jpa-> kevineng963: or rather, do it in the HTIF interrupt

2013-10-08T20:28:44 < kevineng963> I was doing this just for debugging since I was wondering why the first byte was always behind, typically I update it in the main application code
2013-10-08T20:29:19 < jpa-> that's pretty much asking for race conditions
2013-10-08T20:29:20 < kevineng963> and just set a flag during the inerrupty
2013-10-08T20:29:41 < jpa-> but yeah, SPI will take 1 byte in buffer.. on F4, DMA will buffer even more
2013-10-08T20:30:21 < gxti> if you're interrupting after each cycle anyway, just make it a one-shot DMA and start it again after changing the data.
2013-10-08T20:30:22 < jpa-> if you do it in HTIF, you'll have half of the transfer time available to modify the first half of the buffer
2013-10-08T20:30:35 < jpa-> ah yeah, what gxti suggests is good also
2013-10-08T20:31:27 < kevineng963> yeah it is just a one shot tx, thanks for the suggestion

2013-10-08T20:33:35 < trepidaciousMBR> I think you can also use double buffer mode for that, as well as HTIF

2013-10-09T08:58:26 < talsit> depends, are you a games dev?
2013-10-09T08:58:42 < talsit> then probably not

2013-10-09T08:59:40 < dongs> haha
2013-10-09T09:01:45 < talsit> dongs, what are you talking about with the rift?
2013-10-09T09:02:06 < dongs> talsit: nothing, i just see a bunch of fgts trying to "make DIY rift" and im sorta missing what the big deal is
2013-10-09T09:02:17 < dongs> is it just a split screen and some lens?
2013-10-09T09:02:22 < talsit> ah, right
2013-10-09T09:02:47 < talsit> + IMU input with 10ms lag and custom software to do the projection properly
2013-10-09T09:03:37 < dongs> i dont get the lag numbers.
2013-10-09T09:03:39 < dongs> whats hte big deal.
2013-10-09T09:04:04 < talsit> anything above 20ms and your brain calls bullshit on the disconnect between actual motion and the visual representation
2013-10-09T09:04:14 < talsit> it's less for some people
2013-10-09T09:04:24 < dongs> um yeah and why is this hard?
2013-10-09T09:04:34 < dongs> even avr can do < 10ms sensor readings??
2013-10-09T09:05:10 < talsit> going through the whole USB stack, windows drivers, into your program, getting your graphics card not to buffer frames, etc
2013-10-09T09:05:21 < talsit> carmack did a whole bunch of testing
2013-10-09T09:05:34 < dongs> carmack still claims OpenGL > directX
2013-10-09T09:05:38 < dongs> so his opinion on *anything* is invalid
2013-10-09T09:05:43 < dongs> opengl is dead, dead, dead.
2013-10-09T09:05:46 < talsit> a single frame at 60Hz is 16ms
2013-10-09T09:07:04 < talsit> carmack is right
2013-10-09T09:09:38 < GargantuaSauce> i have nvidia 3d vision and it is ok but not awesome
2013-10-09T09:10:05 < GargantuaSauce> it's a 120hz monitor, IR transmitter and shutter glasses
2013-10-09T09:10:55 < GargantuaSauce> as usual, the software support is the limiting factor
2013-10-09T09:11:07 < talsit> the thing about the rift is that the world spins when you move
2013-10-09T09:11:24 < GargantuaSauce> and is thus a wonderful source of nausea
2013-10-09T09:11:36 < talsit> and the response is awesome
2013-10-09T09:11:45 < dongs> uh
2013-10-09T09:11:52 < dongs> how hte fuck does that have anything to do with rift.
2013-10-09T09:12:04 < talsit> but if it drops below 120Hz, you can feel it
2013-10-09T09:12:25 < talsit> well, world spins and the FoV
2013-10-09T09:13:12 < talsit> rift are the only ones doing it properly, that's why it has all to do with the rift
2013-10-09T09:13:12 < dongs> Initial prototypes used a Hillcrest 3DoF head tracker that is normally 125 Hz, with a special firmware that John Carmack requested which makes it run at 250 Hz, tracker latency being vital due to the dependency of virtual reality's realism on response time.
2013-10-09T09:13:16 < dongs> um..
2013-10-09T09:13:56 < dongs> i think my shitcopter is at like >600Hz if I turn off loop limiting
2013-10-09T09:14:11 < dongs> i dont see why a big deal is made out of 125 or even 250Hz.
2013-10-09T09:14:18 < GargantuaSauce> probably because usb
2013-10-09T09:14:24 < talsit> yep, all the way into windows @ 600Hz
2013-10-09T09:14:39 < dongs> yeah, use lunix, then you can get it in at 1.2khz
2013-10-09T09:14:50 < GargantuaSauce> in any case i found the head tracking to be pretty good, what really makes me want to vomit is translation
2013-10-09T09:15:08 < GargantuaSauce> can only take 10 minutes of hl2 or so when i'm moving around
2013-10-09T09:15:24 < talsit> GargantuaSauce: is that the nvidia 3d vision or rift?
2013-10-09T09:15:28 < GargantuaSauce> rift
2013-10-09T09:15:47 < talsit> yeah, i know people that are too sensitive
2013-10-09T09:15:48 < GargantuaSauce> nvidia 3d doesn't fill your field of view so there's no motion sickness, only a little eyestrain
2013-10-09T09:15:53 < talsit> i find it awesome

2013-10-09T09:17:39 < R2COM1> I got geforce nvidia card
2013-10-09T09:18:01 < R2COM1> so turns out I just need 3D glasses
2013-10-09T09:18:07 < GargantuaSauce> which are fucking $100
2013-10-09T09:18:14 < R2COM1> so?
2013-10-09T09:18:19 < talsit> shutter glasses?
2013-10-09T09:18:25 < talsit> how do you sync them?
2013-10-09T09:18:32 < GargantuaSauce> there's an IR transmitter
2013-10-09T09:18:44 < talsit> so he needs the glasses and the transmitter
2013-10-09T09:18:48 < GargantuaSauce> connected over usb, strobes with every new frame
2013-10-09T09:19:14 < R2COM1> then its kinda relatively easier
2013-10-09T09:19:21 < R2COM1> I play with keyboard and mouse
2013-10-09T09:19:29 < R2COM1> and look into 3D looking screen
2013-10-09T09:19:48 < R2COM1> not like with rift.. full glasses but then move with joystick...
2013-10-09T09:20:02 < GargantuaSauce> i play with keyboard+mouse on the rift
2013-10-09T09:20:07 < R2COM1> (because its obvious that you are not Running and walking and climbing stairs in reality when you play)
2013-10-09T09:20:09 < GargantuaSauce> works fine as long as you're familiar with the keyboard
2013-10-09T09:20:29 < R2COM1> if someone attacks you from behind what you do?
2013-10-09T09:20:29 < R2COM1> lol
2013-10-09T09:20:52 < GargantuaSauce> rush to put your dick away

2013-10-09T09:21:47 < R2COM1> if someone is right 180 deg behind
2013-10-09T09:21:51 < R2COM1> in game you just turn
2013-10-09T09:21:56 < R2COM1> here you what.. need to turn head
2013-10-09T09:22:03 < GargantuaSauce> move your mouse/joystick
2013-10-09T09:22:12 < R2COM1> how about head then?
2013-10-09T09:22:15 < R2COM1> since its 3D vision
2013-10-09T09:22:15 < GargantuaSauce> the way hl2 does it is actually pretty fantastic
2013-10-09T09:22:18 < R2COM1> you must do it too
2013-10-09T09:22:23 < GargantuaSauce> you aim with the mouse, and you can turn your head with the rift
2013-10-09T09:22:45 < GargantuaSauce> and the aim reticle has depth so you can tell where you're aiming with parallax
2013-10-09T09:22:55 < R2COM1> its not convenient gameplay damnit
2013-10-09T09:23:07 < R2COM1> if 3D reality then FULL or no!
2013-10-09T09:23:29 < GargantuaSauce> heh
2013-10-09T09:23:30 < R2COM1> at least with 3D glasses + HD monitor its something more to reality but still a "behind PC" idea
2013-10-09T09:23:41 < R2COM1> so I get more effects
2013-10-09T09:23:45 < R2COM1> buts still sit in front
2013-10-09T09:23:52 < R2COM1> something like 3D movies in theaters
2013-10-09T09:23:54 < GargantuaSauce> there are spherical treadmills out there that let you actually walk around
2013-10-09T09:24:15 < R2COM1> how about climb upstairs?
2013-10-09T09:24:33 < GargantuaSauce> so basically you're demanding a full proprioceptory experience
2013-10-09T09:24:36 < dongs> sounds like time for a dickstarer project
2013-10-09T09:24:43 < GargantuaSauce> kickstart the matrix
2013-10-09T09:24:52 < dongs> R2COM's stair walker 3D simulator
2013-10-09T09:25:01 < dongs> make sure to use an arduino
2013-10-09T09:25:05 < dongs> and you'll be guaranteed succes
2013-10-09T09:25:27 < R2COM1> stairs can be emulated kinda with sphere too
2013-10-09T09:26:04 < R2COM1> what I'm trying to say is rift is shit experience
2013-10-09T09:26:07 < R2COM1> looks like it
2013-10-09T09:26:27 < GargantuaSauce> i think it's pretty damn awesome until the nausea kicks in
2013-10-09T09:26:43 < talsit> the resolution is not great at the moment
2013-10-09T09:26:45 < R2COM1> only good if you wanna be "observer" in game
2013-10-09T09:26:50 < talsit> but the experience is awesome
2013-10-09T09:26:58 < GargantuaSauce> it works well for actually playing
2013-10-09T09:27:15 < talsit> if you don't move your head at all, it's like looking into the monitor, except with 3D
2013-10-09T09:27:20 < GargantuaSauce> once i got used to it i could do stuff in hl2 like grab the energy orbs fired at me with the gravity gun a lot more effectively
2013-10-09T09:27:23 < talsit> you don't have to move your head
2013-10-09T09:27:39 < talsit> if you do, it's an added experience
2013-10-09T09:27:41 < R2COM1> the fact that some zombie can come to me from behind and start hitting and i need to rotate head full back 180deg while sitting in front position is fucking horrible
2013-10-09T09:27:57 < talsit> R2COM1: what do you normally do in a game?
2013-10-09T09:27:57 < GargantuaSauce> i don't think you get to say that without trying it
2013-10-09T09:28:10 < talsit> you turn your character with mouse/gamepad, right?
2013-10-09T09:28:15 < R2COM1> yes
2013-10-09T09:28:17 < talsit> same thing with rift
2013-10-09T09:28:28 < R2COM1> but dont I need to take a look at him?
2013-10-09T09:28:58 < talsit> ok, your body and head is disconnected with the rift, meaning, you move & fire in the direction of your body
2013-10-09T09:29:02 < talsit> but you look with your head
2013-10-09T09:29:09 < R2COM1> yes
2013-10-09T09:29:19 < talsit> if your legs turn your body, your body turns your head
2013-10-09T09:29:20 < R2COM1> which means that I wont be able to see anyone behind unless I turn head right?
2013-10-09T09:29:26 < GargantuaSauce> and it's different in some other games
2013-10-09T09:29:38 < talsit> in real life, you do walk around, right?
2013-10-09T09:29:41 < GargantuaSauce> in doom 3 you aim with both the rift and mouse
2013-10-09T09:29:46 < talsit> how does your body/head work?
2013-10-09T09:30:20 < R2COM1> head looks forward mainly
2013-10-09T09:30:30 < dongs> lol?? aim with the mouse?
2013-10-09T09:30:30 < talsit> forward being relative to your body
2013-10-09T09:30:36 < dongs> the fuck would i waste $300 on that trash for
2013-10-09T09:30:41 < dongs> FUCK RIFT; RIFT SUX; RIFT IS DYING; RIFT IS DEAD TO ME; RIFT HIT WTC
2013-10-09T09:30:43 < emeb_mac> linda blair's head looks pretty much anywhere
2013-10-09T09:31:29 < R2COM1> so what you mean GargantuaSauce is that when I move with mouse full 180deg my head will turn too, and then I just fine adjust my look with real head movement
2013-10-09T09:31:37 < talsit> yep
2013-10-09T09:31:58 < talsit> different games can do it differently, but that's a common way
2013-10-09T09:32:07 < R2COM1> then another problem
2013-10-09T09:32:17 < R2COM1> in game I usually look into place I wanna walk to
2013-10-09T09:32:25 < R2COM1> here, if I look in some place while moving, i cant get it done
2013-10-09T09:32:31 < R2COM1> say I move forward
2013-10-09T09:32:32 < GargantuaSauce> in hl2 it's very obvious where you're aiming
2013-10-09T09:32:36 < R2COM1> but looking on a side
2013-10-09T09:32:52 < R2COM1> wonder how KF will perform then with this stuff
2013-10-09T09:33:15 < talsit> KF? Kalman Filter?

2013-10-09T10:53:51 < Robint91> R2COM, the problem is what run length of the cables get important
2013-10-09T10:54:13 < Robint91> R2COM, yep
2013-10-09T10:55:13 < Robint91> R2COM, if the cables are matched good as posseble
2013-10-09T10:55:37 < Robint91> R2COM, I can only have lik 130ps offsets between the signals
2013-10-09T10:56:00 < Robint91> R2COM, If I modulate the clock there is a direct connection between the clock and the sync
2013-10-09T10:56:51 < Robint91> R2COM, you are going to mark the the period of the clock that you want to have the sync
2013-10-09T10:57:14 < Robint91> the sync would be a lower amplitude of the clock
2013-10-09T10:58:16 < Robint91> R2COM, yeah, the Idea is to use sines, and a limiting amplifier so that we always get a nice clock out of it

2013-10-09T11:01:31 < Robint91> R2COM, yep
2013-10-09T11:02:56 < Robint91> *HUGE
2013-10-09T11:03:42 < Robint91> R2COM, we need like 6GHz of bandwidth
2013-10-09T11:04:16 < jpa-> jon1012: why not?
2013-10-09T11:04:45 < Robint91> R2COM, sync pulse is only 1 clock cycle high
2013-10-09T11:07:20 < jon1012> jpa-, because why the fuck would you want to use an 8bit mcu to do that ?
2013-10-09T11:07:38 < Robint91> R2COM, some periode
2013-10-09T11:07:45 < Robint91> R2COM, like 10kHz
2013-10-09T11:09:00 < Robint91> R2COM, that pulse is maybe only 300ps width
2013-10-09T11:10:03 < jpa-> jon1012: because they did so in the 80's also? :)
2013-10-09T11:10:17 < jpa-> jon1012: if you want one with high cpu power, just buy a tablet
2013-10-09T11:11:45 < jon1012> jpa-, yeah but they are adding powerful ics to compensate for low power of the mcu
2013-10-09T11:13:04 < jpa-> nothing wrong with that
2013-10-09T11:13:13 < zyp> jon1012, they had dedicated graphics chips in the 80s too
2013-10-09T11:13:30 < jpa-> IMO it is better design to offload stuff to hardware than just to throw a higher frequency CPU at it

2013-10-09T11:15:57 < Robint91> R2COM, it depends, the rise/fall times need to fall in that period so I can accurately point out which period it is
2013-10-09T11:16:37 < Robint91> R2COM, so for example with a rising edge of the clock the signal levels should be stable
2013-10-09T11:18:39 < Robint91> R2COM, yeah, but I don't really need a mixer
2013-10-09T11:18:46 < Robint91> R2COM, I want a AM modulator

2013-10-09T13:07:33 < Robint91> zyp https://gist.github.com/anonymous/6899045
2013-10-09T13:07:47 < zyp> right, so first you're writing 15 bytes which is stalled, then you are trying to read 64 bytes, which times out, is that right?
2013-10-09T13:10:19 < Robint91> yes
2013-10-09T13:11:16 < zyp> anyway, a stall is a handshake sent by the device, so you need to look at why the device sends a stall
2013-10-09T13:11:36 < zyp> also, same goes for why the device is not sending any data while you're reading

2013-10-09T15:10:55 < zyp> huh?

2013-10-09T15:11:23 < Robint91> now both RX and TX timeout
2013-10-09T15:11:27 < Robint91> instead of that stall
2013-10-09T15:14:49 < zyp> well, you get a timeout if the device doesn't respond in time
2013-10-09T15:15:54 < zyp> the device will NAK an OUT token if it's not ready to receive, and NAK an IN token if it doesn't have anything to send
2013-10-09T15:20:19 < zyp> and if the device keeps doing that for the period you set as a timeout, then you get a timeout
2013-10-09T15:22:58 < Robint91> zyp, could it be also on the libusb code?
2013-10-09T15:23:51 < Robint91> zyp, I do libusb_open_device_with_vid_pid -> libusb_claim_interface -> libusb_bulk_transfer(OUT) -> libusb_bulk_transfer(IN) -> close interface
2013-10-09T15:28:01 < zyp> shouldn't be, device timing out sounds like an error on the device side

2013-10-09T23:26:51 < Laurenceb_> seems they screwed up their address database
2013-10-09T23:28:38 < Laurenceb_> but when they do actually manage to make a pcb correctly its much better than cheap china boards, yes

2013-10-10T02:26:09 < gxti> for some reason i find it amusing that an 8mbit spi flash is cheaper than a microsd socket, let alone the cards
2013-10-10T02:34:21 < zyp> cheaper?
2013-10-10T02:34:26 < zyp> why wouldn't it be?
2013-10-10T02:39:22 < emeb> I find it interesting that you can't really get uSD cards < 4MB any longer.
2013-10-10T02:39:48 < emeb> I guess the lower capacity devices are just too cheap to make any money on them so the mfgs have all moved up to larger capacities.
2013-10-10T02:39:58 < zyp> yeah
2013-10-10T02:39:59 < gxti> 4MB or 4GB?
2013-10-10T02:40:06 < emeb> GB - sorry
2013-10-10T02:40:30 < zyp> heh
2013-10-10T02:40:54 < zyp> I don't think I've even seen a uSD card smaller than 1GB ever
2013-10-10T02:40:57 < emeb> I've got a bunch of embedded systems the work great with 2GB filesystems and it's easier to maintain smaller ones.
2013-10-10T02:41:20 < zyp> just format it for 2GB then
2013-10-10T02:41:31 < emeb> yeah. feels wasteful though. :)
2013-10-10T02:41:36 < zyp> if the card does proper wear leveling, then you'll utilize all the blocks anyway
2013-10-10T02:42:05 < emeb> true - would make it last effectively 4x longer. If it does it properly.
2013-10-10T02:42:21 < gxti> 2GB is also the max for the original standard
2013-10-10T02:42:26 < emeb> based on bunnie huang's teardowns that's likely a big if.
2013-10-10T02:42:29 < zyp> emeb, yep, and probably faster too
2013-10-10T02:42:43 < zyp> gxti, yeah
2013-10-10T02:43:06 < gxti> why they then proceeded to make a standard that could max out within 5 years is beyond me
2013-10-10T02:43:21 < emeb> 640k should be enough for anyone.
2013-10-10T02:43:23 < zyp> the change is not too huge, I think they just replaced some byte addrs with sector addrs
2013-10-10T02:43:24 < gxti> "durr 2GB not enough better only go 32GB nobody needs that much"
2013-10-10T02:45:27 < zyp> by the way, did any of you ever look at using emmc?
2013-10-10T02:45:38 < zyp> digikey doesn't seem to have emmc chips
2013-10-10T02:45:41 < gxti> how big would a usb mass storage host implementation be? maybe i could do that instead of microsd
2013-10-10T02:45:47 < emeb> new beaglebone uses emmc. kind of a PITA
2013-10-10T02:45:48 < zyp> either that or I just suck at searching tonight
2013-10-10T02:46:18 < zyp> gxti, depends on how tailored you make it
2013-10-10T02:46:20 < emeb> what's wrong with uSD?
2013-10-10T02:47:01 < emeb> (besides that it costs more than an 8mbit spi flash?)
2013-10-10T02:48:35 < zyp> a host stack that'll only enumerate msc devices can probably be done as small as a small device stack
2013-10-10T02:48:36 < gxti> not much, i should stop waffling and just go with it. i'm having some mechanical issues that usb wouldn't fix either, though.
2013-10-10T02:48:51 < zyp> and you only need to call a few scsi commands
2013-10-10T02:49:27 < zyp> the hard part is all the error handling :p
2013-10-10T02:49:28 < gxti> the only place to put the socket on the pcb is on the bottom, and i have little enough clearance that the cheapest sockets are actually too tall. but maybe i'd be better off shoving some things around so i don't need to do that anyway.

2013-10-10T02:49:41 < emeb> I've put uSD on a few projects - works fine and is really small. the physical layer is probably a lot smaller than the USB one too.
2013-10-10T02:50:14 < emeb> (code-wise)
2013-10-10T02:50:44 < zyp> true
2013-10-10T02:51:42 < gxti> the other annoying thing is that the socket that i ended up using doesn't leave enough of the card sticking out the end and it barely clears the faceplate of the box
2013-10-10T02:51:52 < zyp> http://cgit.jvnv.net/laks_demo/tree/main.cpp?h=usb_msc <- lines 19-152 is a rudimentary SD driver, you don't get a full usb stack that small :p
2013-10-10T02:52:20 < gxti> yeah i already wrote the SD stack (well, rewrote it from the chibios version)
2013-10-10T02:52:39 < gxti> still got some bugs probably but i'm not exactly doing rocket science here, it's mostly for the bootloader
2013-10-10T02:53:22 < zyp> hmm, I should finish up my bootloader tomorrow

2013-10-10T02:55:12 < gxti> yeah never mind all that shit, i think i can shove some things around and make room for a more suitable uSD socket on the top of the PCB
2013-10-10T02:56:23 < zyp> do you need the socket? just solder the card to the board :p
2013-10-10T02:56:49 < emeb> super glue + ww wire/
2013-10-10T02:57:08 < gxti> if i'm gonna use microsd it might as well be user removable
2013-10-10T02:57:24 < gxti> makes the bootloader a lot more useful!
2013-10-10T02:57:29 < zyp> emeb, I were thinking more just like an LGA :p
2013-10-10T02:57:51 < gxti> i don't think shenzen special cards are reflow-rated
2013-10-10T02:58:25 < zyp> then how are they manufactured? :p
2013-10-10T02:59:08 < gxti> the plastic would get all melty, not that it would really hurt anything probably
2013-10-10T02:59:10 < zyp> (ok, dumb argument, they are probably bonded, not soldered)

2013-10-10T04:53:52 < talsit> hey guys, i've got a problem with a F051 board that's kinda strange and i've run out of option on what to troubleshoot
2013-10-10T04:54:00 < talsit> HSI works fine
2013-10-10T04:54:21 < talsit> HSE works for about 5 seconds, then it goes stupid, doesn't respond to SWD
2013-10-10T04:54:47 < talsit> using a 26MHz TCXO
2013-10-10T04:58:06 < talsit> it gets stranger
2013-10-10T04:58:20 < gxti> flash wait states?
2013-10-10T04:58:25 < upgrdman> 26 sounds high for an f0...?
2013-10-10T04:59:00 < talsit> if i use the HSE directly (STM32_SW_HSE) SWD stops responding, if i use it through PLL (STM32_SW_PLL) serial goes silly after 5s
2013-10-10T04:59:08 < talsit> it supports up to 32MHz
2013-10-10T04:59:13 < talsit> according to datasheet
2013-10-10T04:59:15 < upgrdman> ok
2013-10-10T04:59:24 < gxti> how is the tcxo connected?
2013-10-10T04:59:38 < talsit> i'm using the exact same circuit as on my F4
2013-10-10T04:59:44 < talsit> and that's been working for months
2013-10-10T04:59:59 < talsit> it's a clipped sinewave
2013-10-10T04:59:59 < emeb_mac> R2COM: edison was a tool
2013-10-10T05:00:37 < talsit> gxti: 1nF in series to OSC_IN and a 1M between OSC_IN/OSC_OUT
2013-10-10T05:00:51 < gxti> talsit: sounds good
2013-10-10T05:01:17 < gxti> although technically 26mhz is just out of spec (25mhz max, for f1 anyway)
2013-10-10T05:02:20 < gxti> try dividing it down to < 8mhz using pll or whatever

2013-10-10T05:02:59 < talsit> gxti: according to the datasheet, i can use 4-32MHz crystal oscillator
2013-10-10T05:03:38 < talsit> with PLL, i'm PREDIV = 2 ; PLLMUL = 2
2013-10-10T05:03:49 < talsit> but i'll go down further
2013-10-10T05:03:59 < gxti> weird, f1 is 25mhz max although that's only for the oscillator, 50 is ok for input with the oscillator off
2013-10-10T05:04:26 < gxti> i'm actually also using a 26mhz tcxo but it's not directly connected because there's a mux
2013-10-10T05:04:28 < talsit> yeah, that's why i went for the F0, since i have a known TCXO that i like and use, and it's 26MHz

2013-10-10T05:19:05 < talsit> gxti: will look at it now
2013-10-10T05:19:31 < gxti> your schematic is correct
2013-10-10T05:21:27 < gxti> OSC_IN and OSC_OUT are the inverter, not the TCXO

2013-10-10T05:22:22 < talsit> which is for 0-24MHz
2013-10-10T05:23:20 < talsit> lets try changing to 1
2013-10-10T05:23:46 < gxti> it doesn't explain your findings at 16MHz but it could be that the PLL is not configured correctly or something.

2013-10-10T05:30:05 < talsit> it was 000 on 16MHz and 001 at 26MHz
2013-10-10T05:36:53 < talsit> i may solder up another one to see if it's just faulty
2013-10-10T05:38:58 < talsit> F1? or F0?
2013-10-10T05:39:12 < talsit> F0
2013-10-10T05:40:24 < talsit> checking it out now
2013-10-10T05:41:05 < talsit> i did some checks a while ago
2013-10-10T05:41:11 < talsit> but i forgot what it was
2013-10-10T05:41:19 < talsit> now i'm double/triple checking again
2013-10-10T05:47:13 < talsit> R2COM: yes, it does
2013-10-10T05:48:21 < talsit> the Rf is 200kOhm
2013-10-10T05:48:26 < talsit> internal, yes
2013-10-10T05:48:56 < talsit> yes
2013-10-10T05:49:02 < talsit> the internal is not enough
2013-10-10T05:49:10 < gxti> it's fine.
2013-10-10T05:49:31 < talsit> AN2867 recommends 470k-5M for 20Mhz (even more for lower frequencies)
2013-10-10T05:49:40 < talsit> so 200k is not enough for 26Mhz
2013-10-10T05:50:08 < gxti> well, adding another resistor in parallel reduces resistance, not increases it. but the value really isn't critical.
2013-10-10T05:50:26 < talsit> umm... fuck, yeah, hehe
2013-10-10T05:50:44 < talsit> R2COM: http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/CD00221665.pdf?s_searchtype=keyword
2013-10-10T05:51:38 < gxti> anyway i would probe OSC_OUT and set up MCO and probe that, just to be 100% sure
2013-10-10T05:51:49 < talsit> ok, will do that now
2013-10-10T05:51:53 < gxti> not likely to turn up anything useful but might as well
2013-10-10T05:54:44 < gxti> rofl
2013-10-10T05:59:29 < talsit> R2COM: removed the 1M, same thing
2013-10-10T06:00:20 < talsit> not using external clock, i'm using a tcxo in clipped sinewave
2013-10-10T06:01:15 < talsit> OSC_OUT is flat @ 0V
2013-10-10T06:02:02 < gxti> talsit: then comes the dumb question, you did actually turn the HSE on and wait for the ready bit to set, right?
2013-10-10T06:02:10 < talsit> well, not really i'm getting a "sine" @ 26Mhz with about 30mV p-p
2013-10-10T06:02:16 < talsit> gxti: yes
2013-10-10T06:02:50 < talsit> 0
2013-10-10T06:02:59 < talsit> ish
2013-10-10T06:03:18 < gxti> curious.
2013-10-10T06:03:19 < talsit> 3mV
2013-10-10T06:03:34 < gxti> could just be bleeding through the resistor from the input i guess?
2013-10-10T06:03:35 < talsit> 30-40mV p-p
2013-10-10T06:05:10 < talsit> on TCXO: 1.24V p-p centred around 0.5V ; on OSC_IN: 1.24V p-p, centre: 0.144V
2013-10-10T06:06:51 < talsit> -0.44, my scope says
2013-10-10T06:07:07 < talsit> but yes
2013-10-10T06:08:13 < talsit> ok, time to get the loupe out and check again
2013-10-10T06:08:13 < talsit> yep
2013-10-10T06:10:28 < talsit> wait a sec, i just tested my F4 board that has the same TCXO circuit, and i'm getting the same 1.24Vp-p but centered around 1.56C
2013-10-10T06:10:31 < talsit> 1.56V
2013-10-10T06:11:02 < gxti> right, that's what it's supposed to be doing. the goal of the feedback resistor is to use the internal oscillator block to center it at precisely the middle of the linear region.
2013-10-10T06:11:32 < gxti> probably OSC_OUT is misconfigured or faulty or something, and is clamping to ground.
2013-10-10T06:12:13 < gxti> R2COM's suggestion is the alternate way of doing this type of thing, it does not require that OSC_OUT works although it does require that the input buffer be configured sanely and the duty cycle might not be exactly 50% since you're manually configuring the center with resistors.
2013-10-10T06:23:08 < talsit> ok, so it looks like OSC_OUT is faulty
2013-10-10T06:23:19 < talsit> on my F4, that works, it's around 1.3V
2013-10-10T06:23:25 < talsit> on this F0, it's 0
2013-10-10T06:23:44 < talsit> i lifted it off the pad, and still same reading
2013-10-10T06:24:46 < gxti> could be gpio configuration issue, perhaps?
2013-10-10T06:25:06 < talsit> i'll look at that now, good idea
2013-10-10T06:25:20 < gxti> it might want that pin to be analog input (even though it's really more of an analog output)
2013-10-10T06:26:33 < talsit> they are both set to input, pushpull, 2M, floating, af0
2013-10-10T06:27:07 < upgrdman> R2COM: what's t1?
2013-10-10T06:27:25 < talsit> transmission line
2013-10-10T06:27:40 < upgrdman> what's that? a delay line?
2013-10-10T06:27:54 < englishman> which spice is that R2COM?
2013-10-10T06:27:57 < gxti> it's not a "real" component, it simulates transmission lines
2013-10-10T06:28:06 < talsit> ltspice
2013-10-10T06:28:07 < gxti> englishman: ltspice
2013-10-10T06:28:23 < englishman> it looked like ltspice but where are all the cool components?like 50ohm source etc
2013-10-10T06:28:31 < gxti> rather, transmission lines are real things but not something you plop down on a PCB. normally, anyway.
2013-10-10T06:29:10 < upgrdman> so it's just a model for parasitics?
2013-10-10T06:29:15 < englishman> probably me being incompatible with ltspice
2013-10-10T06:29:24 < gxti> upgrdman: not exactly
2013-10-10T06:29:24 < englishman> model for reflections?
2013-10-10T06:29:47 < gxti> it's an ideal transmission line, and transmission lines are parasitic versions of ideal wires :P
2013-10-10T06:30:24 < talsit> i'll solder up a new board after lunch, see if i have better luck with that one

2013-10-10T06:44:40 < emeb_mac> I lolled when I found out that doing integer operations required another toolbox.
2013-10-10T06:45:12 < emeb_mac> but I still fork over $1800/yr for maintenance on it.
2013-10-10T06:46:09 < emeb_mac> what do you mean?
2013-10-10T06:46:47 < emeb_mac> heh

2013-10-10T12:14:32 < dongs> zyp: where you want the completed shit shipepd
2013-10-10T12:14:37 < dongs> fedex? or ems?
2013-10-10T12:29:02 < zyp> hmm, home addr should be fine, fedex or ems doesn't matter, I'll have to pick it up at the same place when I get home from vacation anyway, so just pick the cheapest
2013-10-10T12:32:03 < zyp> fedex will maybe give less hassle with customs processing, customs tend to hold shipments and ask for an invoice when they get ems shipments
2013-10-10T12:48:07 < dongs> you dont have a fagex account to ship to do you?
2013-10-10T12:48:16 < dongs> ship it to your job for f ree w/their account d;
2013-10-10T12:52:07 < zyp> I don't think fedex accounts is a big thing in norway
2013-10-10T12:54:31 < zyp> by the way, which value will they put on the customs forms on the package?
2013-10-10T12:54:43 < dongs> whatever you want
2013-10-10T12:54:49 < dongs> it can be pcb assembly service at like $1/ea oer osmeshit.
2013-10-10T12:54:57 < dongs> thats what I usually ship shit by
2013-10-10T12:55:15 < zyp> sounds good
2013-10-10T12:55:41 < zyp> by the way, how about those pics you mentioned?

2013-10-10T12:57:59 < Laurenceb> im vac forming at 200C and the ABS is holding up nicely
2013-10-10T12:58:10 < zyp> umm
2013-10-10T12:58:19 < zyp> why is the LED2 connectors not populated?
2013-10-10T12:59:12 < dongs> i duno if that pic was before they started soldering dips
2013-10-10T12:59:17 < dongs> they probably just stuck them in
2013-10-10T12:59:19 < dongs> will beep to confirm

2013-10-10T13:03:46 < karlp> hmm, new 7 port usb hub I got reports as 2 four port hubs
2013-10-10T13:03:52 < dongs> zyp: yea that was old pic
2013-10-10T13:03:59 < dongs> shit's done and all pins are in
2013-10-10T13:04:09 < zyp> good
2013-10-10T13:04:23 < zyp> karlp, because they use two 4-port chips cascaded
2013-10-10T13:04:38 < zyp> I think it's pretty common to do that
2013-10-10T13:04:55 < karlp> yeah, I just remember looking at usb hub chips, and 7 port usb chips was common too,
2013-10-10T13:05:10 < karlp> port "8" has differnet "Hub Port Status" flags.
2013-10-10T13:10:47 < dongs> there are no 8port hub chipos
2013-10-10T13:10:49 < dongs> chips
2013-10-10T13:10:58 < dongs> there's 7 with 1 upstream
2013-10-10T13:11:59 < zyp> I looked inside an 8-port hdmi-switch yesterday
2013-10-10T13:12:19 < zyp> contained two 4-port switch chips connected to a 2-port chip
2013-10-10T13:12:25 < dongs> cutee.
2013-10-10T13:13:10 < zyp> I think the chips was from the same guys that made those chips you used for the hdmi-parallel-dp stuff, forgot what they was called
2013-10-10T13:13:16 < dongs> ITE
2013-10-10T13:13:19 < dongs> most likely

2013-10-10T16:35:47 < qyx_> i am trying to use that online tool eDesignSuite on their web
2013-10-10T16:36:13 < DanielHolth> would you say it's pretty easy to brick stm32s if you screw up the pin configs?
2013-10-10T16:36:15 < qyx_> and they restrict the input forms to KEYS with numbers only
2013-10-10T16:36:42 < DanielHolth> any hints on unbricking a F0 discovery board
2013-10-10T16:36:52 < zyp> unbricking?
2013-10-10T16:36:54 < jpa-> DanielHolth: if you have a proper programmer, no, it shouldn't be too easy
2013-10-10T16:36:58 < zyp> how did you brick it?
2013-10-10T16:37:10 < qyx_> on EN layout everywhing is okay but i cannot enter anything on different layout when you yre required to use shift to enter numbers :S
2013-10-10T16:37:13 < jpa-> DanielHolth: you need to connect under reset to recover processor when the software disables SWD
2013-10-10T16:37:18 < DanielHolth> configured PA4 as DAC and analog input
2013-10-10T16:37:22 < DanielHolth> which should be OK
2013-10-10T16:37:35 < DanielHolth> although I was worried if I configured the same pin as a digital out and a dac out that I colud short it
2013-10-10T16:37:45 < jpa-> DanielHolth: ah.. that shouldnt
2013-10-10T16:37:52 < jpa-> cause any problems
2013-10-10T16:37:56 < DanielHolth> meh
2013-10-10T16:38:27 < DanielHolth> so, openocd says "processor id is all zeroes" and can't connect to the stlink at all unless the reset button is forced. very annoying.
2013-10-10T16:40:19 < DanielHolth> i've noticed that the arduino is a bit easier :-)
2013-10-10T16:41:06 < jpa-> the stlink tool on windows is smart enough to recover from this automatically (on stlink v2, anyway) :)
2013-10-10T16:41:21 < DanielHolth> that sounds like a good idea
2013-10-10T16:41:28 < DanielHolth> mass erase ftw

2013-10-10T16:50:28 < jpa-> DanielHolth: zyp has some nice stuff here: http://cgit.jvnv.net/laks/tree/
2013-10-10T16:50:55 < GargantuaSauce> a template argument for timer period? e___e
2013-10-10T16:51:04 < DanielHolth> which stm32 do you prefer?
2013-10-10T16:51:10 < DanielHolth> It was baffling to a C++ templates noob
2013-10-10T16:51:24 < jpa-> it's plain silly to have that as a template argument :)
2013-10-10T16:51:42 < DanielHolth> However unfortunately that particular library is now unmaintained.
2013-10-10T16:52:05 < DanielHolth> It computes the prescalar etc. at compile time.
2013-10-10T16:52:35 < jpa-> it could do that equally well with just a inline function.. but i guess the template argument could force it to be inlined
2013-10-10T16:53:24 < DanielHolth> I can't say the whole thing was perfect, and it took too long to figure out it was unmaintained, but overall it was much nicer and less tedious than the ST libs.
2013-10-10T16:53:35 <+Steffan-> I wonder how it went with this lib from erlkoenig.
2013-10-10T16:53:52 < DanielHolth> modern gcc is expected to inline like crazy.
2013-10-10T16:54:05 < zyp> my lib relies on gcc inlining
2013-10-10T16:54:14 < zyp> works good enough for me
2013-10-10T16:54:18 < DanielHolth> neat
2013-10-10T16:54:58 < jpa-> zyp: and Posterdati will recommend it also ;)
2013-10-10T16:55:04 < zyp> I wonder
2013-10-10T16:55:05 < zyp> :p
2013-10-10T16:55:14 < DanielHolth> that lib mostly did not use template arguments as a user-facing feature.
2013-10-10T16:55:38 < DanielHolth> you are also targeting the F1 and F4
2013-10-10T16:56:08 < zyp> my lib is targeting any cortex-m
2013-10-10T16:56:28 < zyp> I've used it with F1, F3 and F4 so far, but support for others shouldn't be very hard
2013-10-10T16:56:53 < zyp> I have some experimental LM4F and LPC4300 branches somewhere, but they aren't very useful yet
2013-10-10T16:57:08 < DanielHolth> neat
2013-10-10T16:59:09 < DanielHolth> another cool thing about the libstm32pp was the use of weak symbols for the interrupt table. so declaring an interrupt:TIM3() function automatically overrode the default noop handler
2013-10-10T16:59:19 < zyp> heh
2013-10-10T16:59:23 < dongs> uh..
2013-10-10T16:59:24 < zyp> every lib does that
2013-10-10T16:59:26 < dongs> pp = c++?
2013-10-10T16:59:34 < DanielHolth> yes
2013-10-10T16:59:39 < zyp> (including mine)
2013-10-10T16:59:41 < dongs> aidsssssss
2013-10-10T17:00:01 < DanielHolth> perhaps I'm easily impressed
2013-10-10T17:00:08 < dongs> I prefer CMSIS-defined handler names
2013-10-10T17:00:09 < DanielHolth> you should start using #pragma once
2013-10-10T17:00:20 < dongs> which is one of 248723894723 reasons why libopenstm32 sucks
2013-10-10T17:00:32 < zyp> DanielHolth, let me impress you some more: http://cgit.jvnv.net/laks/tree/interrupt/interrupt.cpp
2013-10-10T17:01:16 < zyp> template-stuff makes it impossible to typo the interrupt name without the compiler shouting at you
2013-10-10T17:01:38 < DanielHolth> crazy
2013-10-10T17:01:47 < DanielHolth> look at all those <>

2013-10-10T17:02:26 < DanielHolth> have you gotten around to using lambdas?
2013-10-10T17:02:49 < zyp> no, but I'm using a bunch of other neat C++11 features
2013-10-10T17:02:54 < zyp> like variadic templates

2013-10-10T17:04:20 < zyp> some shit I were experimenting with once
2013-10-10T17:06:14 < DanielHolth> the F0 is interesting. Most of the peripherals appear to be like the F3/F4 ones. IIUC the F1 is the oldest.
2013-10-10T17:06:23 < zyp> yep
2013-10-10T17:06:36 < DanielHolth> I like that it's cheaptastic and small
2013-10-10T17:06:44 < jpa-> i like L1 the best.. F0 seems to only be cheap, and quite limited
2013-10-10T17:06:53 < zyp> adding F0 support to my lib is probably around as hard as adding F3 support
2013-10-10T17:07:19 < zyp> http://cgit.jvnv.net/laks/commit/?id=ac17bb0 <- which was about this hard :p
2013-10-10T17:08:18 < zyp> jpa-, how is the price of L1 vs F3?
2013-10-10T17:10:54 < jpa-> zyp: L1 is a tiny bit cheaper.. not so much that it would matter for a hobbyist
2013-10-10T17:11:17 < jpa-> i guess it depends a lot on whether you need performance or power saving more..

2013-10-10T17:14:33 < dongs> F3 has good GPIO
2013-10-10T17:15:16 < zyp> I were also planning to use the comparators, but it doesn't look like I have to
2013-10-10T17:15:38 < zyp> some of the inputs are hooked up to comparator inputs, but currently I'm reading them in normal digital mode, which works fine

2013-10-10T17:15:54 < jpa-> it's annoyingly difficult to make use of the power saving features of L1.. i was planning to keep the CPU clock at constant 4 MHz because i don't need more, but apparently USB can't work if PCLK1 is less than 8 MHz
2013-10-10T17:16:23 < zyp> if you do usb it probably doesn't matter much anyway
2013-10-10T17:16:33 < jpa-> i only do usb occassionally
2013-10-10T17:16:43 < zyp> you could just clock up when usb is connected
2013-10-10T17:16:56 < jpa-> yeah.. but then i would need to reconfigure every timer & usart
2013-10-10T17:17:14 < zyp> can't they run of a different clock source that doesn't change?
2013-10-10T17:18:23 < jpa-> i guess i could divide down PCLK2.. still i'd worry a bit about the transients
2013-10-10T17:18:57 < zyp> no, that's not what I mean
2013-10-10T17:19:24 < zyp> doesn't L1 have a clock source selection for each single peripheral?
2013-10-10T17:19:33 < jpa-> hum.. not AFAIK
2013-10-10T17:20:05 < jpa-> USB already runs from a different clock source, but for some reason it stops working if PCLK1 (for cpu interface to the usb peripheral) is too low

2013-10-10T17:26:17 < zyp> ah, it's the F3 that can do it
2013-10-10T17:26:57 < zyp> RCC_CFGR3 in F303 can switch clock source for each UART
2013-10-10T17:27:13 < zyp> between PCLK, SYSCLK, LSE and HSI
2013-10-10T17:27:24 < jpa-> i couldn't find any note about minimum PCLK1 frequency for USB, though.. but when i try it, the processor detects USB reset ok, i can see the host sending SETUP setaddr packet, but the processor newer gets the interrupt about an incoming packet
2013-10-10T17:27:30 < jpa-> *never
2013-10-10T17:28:21 < jpa-> but i guess it's low power enough at 16 MHz anyway.. most of the power usage will be from the e-ink
2013-10-10T17:28:29 < zyp> I2C can be switched between PCLK and HSI, and TIM1/8 can be switched between PCLK2 and PLLVCO
2013-10-10T17:28:52 < zyp> so F3 timers can actually run at up to 2xSYSCLK
2013-10-10T17:30:41 < zyp> weird that F3 has the clock switch feature, but L1 doesn't

2013-10-11T01:33:19 < zyp> it only fits the right way due to the shroud, that's keying enough for me

2013-10-11T01:40:02 < zyp> I really recommend getting the shrouded one, unless the board is sitting inside an enclosure or are otherwise protected
2013-10-11T01:40:50 < zyp> unshrouded 1.27mm pitch headers are way too easy to damage otherwise
2013-10-11T01:42:34 < esden> zyp: what I linked is shrouded in a sense
2013-10-11T01:42:54 < esden> it just uses much less space then a fully shrouded connector
2013-10-11T01:43:15 < zyp> it's the one that's shrouded only on the long sides?

2013-10-11T01:43:56 < zyp> ah, yeah
2013-10-11T01:44:21 < zyp> I haven't encountered those myself, but they are probably also good
2013-10-11T01:44:43 < esden> this is what keil and friends recommend

2013-10-11T01:45:35 < zyp> yeah, I've seen
2013-10-11T01:46:16 < zyp> not sure how useful the shroud on the ETM variant is though, apart from keying

2013-10-11T03:23:03 < gxti> usb b is seeming like an attractive way to get power into this board, pretty much idiotproof. and it turns out that the usb pins on the stm32 aren't allocated yet so i may as well connect it up
2013-10-11T03:44:48 < dongs> is this the NTP thing
2013-10-11T03:51:46 < gxti> ya

2013-10-11T03:53:00 < emeb> gxti: what processor?
2013-10-11T03:53:01 < gxti> originally i had a smps module that takes 7-36V with the idea that you could connect it straight to a lead-acid battery in a shack in the mountains or something, but it's probably not really that valuable to do it in the box
2013-10-11T04:02:08 < gxti> emeb: f107
2013-10-11T04:02:49 < dongs> why the fuck do phone lcds need negative voltage
2013-10-11T04:03:10 < emeb> gxti: so no USB bootloader. :(
2013-10-11T04:03:17 < dongs> pfft?
2013-10-11T04:03:24 < dongs> ST's usb lib bootloader works w/o changes
2013-10-11T04:03:27 < dongs> dfuboot or wahtever
2013-10-11T04:03:37 < dongs> takes like 5 minutes to set it up for your hardware
2013-10-11T04:03:44 < dongs> including USB disconnect (if any), leds/whatever.
2013-10-11T04:04:01 < gxti> yeah and i don't even really need it, just SD is fine
2013-10-11T04:05:30 < dongs> http://www.rsp.renesas.com/en/news/2012/news20120418.htm oh, thats how they do it
2013-10-11T04:05:52 < dongs> they're skipping TCON and just made everything onechip
2013-10-11T04:10:16 < talsit> gxti: i lifted up my f051 from yesterday, placed down a new one, and i'm getting the same voltages at OSC_IN
2013-10-11T04:10:46 < talsit> very disconcerning
2013-10-11T04:12:12 < gxti> talsit: probe the resistance from osc_out to gnd, i bet it's being pulled low by the uc
2013-10-11T04:12:52 < gxti> that would explain why osc_in is centered at zero and osc_out has negligible signal
2013-10-11T04:13:02 < talsit> 15MOhm
2013-10-11T04:14:31 < talsit> actually, not even that
2013-10-11T04:16:17 < talsit> yeah, 15MegaOhm
2013-10-11T04:16:24 < talsit> which doesn't look like a short
2013-10-11T04:17:06 < talsit> on my F4, it's 20MegaOhm

2013-10-11T05:03:18 < gxti> i'm not sure what osc_out does in bypass mode honestly, i avoid using it for gpio because i think it gets clamped anyway
2013-10-11T05:08:20 < gxti> also i spent longer than i care to admit getting *my* tcxo working because the first board worked normally and the second one would not clock at all. turned out i forgot to configure the gpio to drive the mux that selected the clock, and it floated just right on the first board :p
2013-10-11T05:08:41 < talsit_idiot> nice
2013-10-11T05:08:51 < gxti> identical boards, can't be software right?
2013-10-11T05:09:23 < talsit_idiot> hey, now that i have a working board, i can actually do, you know, work
2013-10-11T05:10:13 < talsit_idiot> do you have any recommendations on chips that you've used to charge a single cell lipo and supplying power, with auto-switch over?

2013-10-11T05:10:39 < talsit_idiot> but none of them have protection to not over-discharge the LIPO

2013-10-11T06:58:40 < dongs> indeed
2013-10-11T06:58:47 < dongs> lazy to start on mipi adapter.
2013-10-11T06:59:30 < emeb_mac> working on a board w/ that NCP1532 switcher. That thing is tiny.
2013-10-11T07:00:19 < dongs> cool
2013-10-11T07:00:25 < dongs> its in a bunch of my boards now.
2013-10-11T07:01:58 < emeb_mac> I found some teeny inductors for it - about 3mm too.
2013-10-11T07:02:10 < emeb_mac> good for 1A apparently, so they should be fine.
2013-10-11T07:02:19 < dongs> i use uh
2013-10-11T07:02:37 < dongs> VLF3010AT-2R2M1R0
2013-10-11T07:02:41 < dongs> and there's a clone
2013-10-11T07:02:51 < dongs> ELL-VGG2R2N
2013-10-11T07:02:54 < dongs> thats cheapr
2013-10-11T07:04:09 < emeb_mac> aha - the VLF3010 is what I'm using.
2013-10-11T07:04:23 < emeb_mac> the pix you posted a while back seemed different from those.
2013-10-11T07:05:45 < emeb_mac> that ELL part use the same footprint as the VLF?
2013-10-11T07:23:02 < dongs> yes
2013-10-11T07:23:08 < dongs> wel, not really but it works in VLF footprint
2013-10-11T07:23:12 < dongs> ive been using them interchangeably
2013-10-11T07:23:26 < dongs> you could just enlarge vlf pads a bit and it'll work for both
2013-10-11T07:23:46 < dongs> ell is probably the one I posted, with D> mark on it
2013-10-11T07:27:33 < emeb_mac> kk
2013-10-11T07:27:55 < emeb_mac> the VLF ones are nice because there's lots of room between the pads for other routing.

2013-10-11T07:30:21 < dongs> I just looked at ncp evalboard gerbers
2013-10-11T07:30:24 < dongs> and made my shit similar
2013-10-11T07:30:31 < dongs> i got it working nicely with 0603 parts and 0805 caps
2013-10-11T07:30:36 < dongs> doesnt take a lot of space
2013-10-11T07:30:44 < dongs> all single layer too
2013-10-11T07:30:50 < dongs> except for vfb pin
2013-10-11T07:32:19 < emeb_mac> I'm only routing VIN under one of the inductors.
2013-10-11T07:33:00 < emeb_mac> but I didn't follow their layout. Did look at the one in the datasheet and mine is fairly similar.

2013-10-11T08:33:57 < emeb_mac> need to think of something cool to do with these last few F405 parts I've got laying around.
2013-10-11T08:35:30 < dongs> stm32... can it do 1.8V vddio?
2013-10-11T08:35:49 < emeb_mac> dunno - never looked...
2013-10-11T08:36:28 < dongs> 2.0V to 3.6V vdd
2013-10-11T08:36:28 < dongs> hmm
2013-10-11T08:36:29 < dongs> fuck
2013-10-11T08:37:33 < dongs> that kinda puts a dent on my idea of just running all I/O at .18
2013-10-11T08:37:33 < dongs> 1.8
2013-10-11T08:37:33 < gxti> what's the voltage tolerance on the 1.8V parts? :p
2013-10-11T08:37:33 < dongs> im not gonna run them out of spec
2013-10-11T08:37:33 < gxti> so what's the spec then
2013-10-11T08:37:37 < emeb_mac> you sure about that? the F405 datasheet I have says VDD can go down to 1.8V
2013-10-11T08:38:26 < dongs> F103 isnt
2013-10-11T08:38:31 < emeb_mac> ah
2013-10-11T08:38:40 < emeb_mac> the F4xx runs a lot lower
2013-10-11T08:39:00 < emeb_mac> Vcore is 1.2xx something, so the I/O can go lower too
2013-10-11T08:39:01 < dongs> well fuckit
2013-10-11T08:39:04 < dongs> looks liek i can do 1.8 or 3.3
2013-10-11T08:39:07 < dongs> oll just run everything at 3.3
2013-10-11T08:39:19 < dongs> i thought one part was 1.8 only

2013-10-11T12:07:26 < karlp> zyp: by keyed I just meant the shroud yeah,
2013-10-11T12:07:43 < karlp> esden: that samtec part is pricey as hell, but I do like the partial shrouding stuff.
2013-10-11T12:08:45 < karlp> going to go with 1175-1627-ND which is fully shrouded, but only 48c, vs 3. 25 for yours :)  (that's also through hole, but there's a smt version of it)
2013-10-11T12:09:01 < karlp> (also, it's in stock, unlike the samtec part)
2013-10-11T12:09:18 < esden> karlp: yeah samtec ... still did not find a cheaper alternative that would not either be huge having a full shroud or not having a shroud at all, surprising that alibaba is totally unhelpful with this :)
2013-10-11T12:09:29 < esden> karlp: get it from samtec directly
2013-10-11T12:09:32 < esden> not from digikey
2013-10-11T12:09:56 < esden> if you need samples they are also very good about that
2013-10-11T12:10:26 < esden> and fairly quick
2013-10-11T12:10:31 < karlp> I've got things form samtect before directly,
2013-10-11T12:10:34 < karlp> it, worked,
2013-10-11T12:10:43 < karlp> but at least what I got last time, was no samples, or at least, no samples to iceland
2013-10-11T12:11:01 < karlp> and they shipped them in separate gigantic parcels via fedex
2013-10-11T12:11:20 < karlp> so the local fedex cunts gleefully charged me "customs processing" on both of the parcels separately.
2013-10-11T12:11:37 < esden> mhh, I have a box full of different samples from them here
2013-10-11T12:11:39 < karlp> it worked out more expensive than getting them on digikey and just paying for normal digikey shipping.
2013-10-11T12:11:48 < esden> they were free
2013-10-11T12:12:13 < karlp> also, I'm jumping on a digikey order at work, so it's digikey or nothing :)
2013-10-11T12:12:19 < esden> I have no idea about iceland though
2013-10-11T12:13:07 < karlp> the board they are going on has plenty of space for full shrouding, but I've written your part number down for later :)
2013-10-11T12:13:16 < karlp> also, while I've got your attention:

2013-10-11T15:06:43 < Bird|lappy> 2 questions: 1) I'm debating whether I should get a f0 or a f1 discovery board
2013-10-11T15:07:28 < Bird|lappy> (f0 is a couple $ cheaper, f1 is M3 vs the f0's M0 core)
2013-10-11T15:07:34 < jpa-> Bird|lappy: not F1 atleast
2013-10-11T15:07:45 < jpa-> F1 has stlinkv1 which is crap
2013-10-11T15:07:57 < jpa-> Bird|lappy: what do you want to do? high performance, low cost or low power?
2013-10-11T15:08:44 < jpa-> of the more modern boards, F4 probably has the best software support.. F0 is a bit small for e.g. chibios
2013-10-11T15:09:14 < dongs> get 429i-disco
2013-10-11T15:09:14 < Bird|lappy> low cost/power, I'm not interested in super-high-performance stuff
2013-10-11T15:09:14 < dongs> Bird|lappy: low cost = get f103
2013-10-11T15:09:14 < Posterdati> Bird|lappy: what about f4?
2013-10-11T15:09:14 <+Steffan-> Isn't the F030 cheaper? .. 39c or so?
2013-10-11T15:09:14 <+Steffan-> :P
2013-10-11T15:09:33 < jpa-> Bird|lappy: i would recommend L1 or F0 in that case
2013-10-11T15:09:43 < Bird|lappy> Posterdati, f4 is way too heavyweight for what I am trying to learn.  and I'm not interested in dealing with things like chibios
2013-10-11T15:10:09 < Bird|lappy> jpa-, got it.  f0 it will be :)
2013-10-11T15:11:01 < Bird|lappy> 2nd question: for the f0 parts, do you folks use a convenience library for I/O devices, or just work with a header with e.g. register bit defs?
2013-10-11T15:11:07 < jpa-> you can always put any other STM32 on your own board and program it with the discovery anyway
2013-10-11T15:11:33 < jpa-> Bird|lappy: i usually use the header directly for simple stuff and chibios for more complex stuff
2013-10-11T15:11:46 < jpa-> it seems everyone uses a different library
2013-10-11T15:13:17 < jpa-> some use ST's own stdperiph helper functions, some use coocox, some use some keil stuff, and there are plenty of less popular libraries out there also (laks, stm32pp, stm32plus, libopencm3, etc.)

2013-10-11T16:28:13 < jpa-> yay for windows & st ;)
2013-10-11T16:29:47 < DanielHolth> what's the openocd equivalent of "connect under reset"?
2013-10-11T16:30:52 < jpa-> it was what i suggested.. but that was the magic parameters given by PaulFertser and i haven't tried them myself
2013-10-11T16:31:23 < jpa-> (i only have stlinkv1 which does not have a reset line anyway)
2013-10-11T16:31:38 < DanielHolth> it seems like every supported jtag has a different set of openocd commands
2013-10-11T16:37:27 < gxti> DanielHolth: "reset halt" i think, been a while since i used openocd
2013-10-11T16:48:37 < karlp> connect under reset, he means the reset tsrt/reset tsrt_and_srst/ type commands in the config file

2013-10-11T16:56:47 < trepidaciousMBR> Bird|lappy: Smaller chips are not necessarily easier to learn to use, the F4 has good demos, lots of people using it, and you probably won't run out of any resources, which makes things easier
2013-10-11T16:57:11 < trepidaciousMBR> Not that there is anything wrong with the F103, just that smaller is not easier :)
2013-10-11T16:59:08 < karlp> I'd highly recommend choosing a chip with the same gpio configuration as the one you want to use eventually
2013-10-11T16:59:19 < karlp> no need ever looking at f1 gpio if you're going to use anything else.
2013-10-11T16:59:44 < trepidaciousMBR> Yeah, I'd heard its a bit weird, also peripheral remapping is not as good?

2013-10-11T17:29:40 < dongs> hes sill trying to decide?
2013-10-11T17:29:47 < dongs> Bird|lappy: just use F103C8/CB
2013-10-11T17:31:18 < jpa-> DanielHolth: F4 has a bit different USB & DMA
2013-10-11T17:31:40 < jpa-> dongs: nah, just random ramblings now :)
2013-10-11T17:33:15 < karlp> dongs: f103 doesn't come on any disco board though.
2013-10-11T17:36:21 < dongs> sure it does
2013-10-11T17:36:24 < dongs> matchboxarm or my shit
2013-10-11T17:36:26 < dongs> :)
2013-10-11T17:36:40 < dongs> F100 is on some -disco
2013-10-11T17:36:51 < gxti> better f103 than f100 though

2013-10-11T18:26:22 < trepidaciousMBR> I couldn't work out the pricing - looking at say digikey prices, it seems like there are some tiny chips, say 8-16KiB, and some huge ones like the F4, but the 8-16KiB chips aren't that cheap, and there is nothing much in the middle except the F103, I guess they plan to keep the F103 going to fill the gap?

2013-10-11T18:28:51 < dongs> for ~$10
2013-10-11T18:29:00 < dongs> and then you can use it with whatever evalboard/bare chip

2013-10-11T18:41:00 < trepidaciousMBR> dongs: Yup I came to the conclusion the F103 was the best option, left me wondering what the F0 line is meant to be for :)
2013-10-11T18:41:00 < dongs> trepidaciousMBR: companies buying 100k at a time and caring about cost
2013-10-11T18:41:01 < dongs> when you buy 100k of F0 it becomes cheap.
2013-10-11T18:41:19 < trepidaciousMBR> dongs: I guess that makes sense, at even 1000off it doesn't look cheap at all
2013-10-11T18:41:30 < dongs> not at digikey prices, no
2013-10-11T18:41:37 < dongs> but proper distributor prices is not so bad
2013-10-11T18:41:37 <+Steffan-> Isn't the F0 supposed to be $0.39?
2013-10-11T18:41:47 < dongs> i think it gets serious at like 10k

2013-10-11T18:43:23 < gxti> also i like the complete lack of grommets for a flat flex cable passing through a rough metal slot
2013-10-11T18:43:24 < dongs> BUT ITS FOR ASPIEBERRYPI CAMERA!!!
2013-10-11T18:43:59 < trepidaciousMBR> Might be less of a reflection on Raspberry Pi mania, and more on the fact that it looks like it was put together by a chimp with a hammer.

2013-10-11T19:14:40 < karlp> a pony!
2013-10-11T19:14:54 < Laurenceb_> F2
2013-10-11T19:14:57 < Laurenceb_> in general
2013-10-11T19:15:50 < Laurenceb_> but no F429 there?
2013-10-11T19:16:02 < jpa-> it's just F4 in there
2013-10-11T19:16:24 < Laurenceb_> yeah no 2M flash
2013-10-11T19:16:36 < jpa-> hmm yeah
2013-10-11T19:16:36 < englishman> more than $4 for f1 128k? ouch
2013-10-11T19:16:44 < jpa-> hardcoded the upper Y range :D

2013-10-11T19:18:16 < Laurenceb_> thats $20
2013-10-11T19:18:21 < Laurenceb_> ah
2013-10-11T19:18:46 < gxti> rofl, $13 for an 8bit mcu
2013-10-11T19:18:49 <+Steffan-> And no < 1$ because those aren't in stock either.
2013-10-11T19:19:01 < gxti> going to need a bigger segment register
2013-10-11T19:19:03 < Laurenceb_> gxti £13, $20
2013-10-11T19:19:11 < gxti> durr thanks digikey
2013-10-11T19:19:40 < Laurenceb_> more expensive than any of the stm32 stuff jpa plotted
2013-10-11T19:19:46 < Laurenceb_> epic lulz
2013-10-11T19:20:04 < gxti> let's see what features it has
2013-10-11T19:20:20 <+Steffan-> Don't, just don't
2013-10-11T19:20:41 <+Steffan-> do it.
2013-10-11T19:21:24 < gxti> pretty much nothing
2013-10-11T19:22:31 <+Steffan-> You could waste more time.. also look at some PICs, renesas etc.  8 bit crap.
2013-10-11T19:22:49 < gxti> $2 PICs have more peripherals than this
2013-10-11T19:23:09 < karlp> for creating countingo f "more" and $2 ?
2013-10-11T19:24:56 < gxti> you could take any other cheap 8bit mcu and add a spi flash and it would do more, cost less, and take less board space. but i guess someone was dumb enough to ask for it.
2013-10-11T19:28:01 < jpa-> someone thinking "i'll make the biggest arduino evar!"

2013-10-11T19:50:38 < kevineng963> quick clarification question.  I am using the STM32f103RC (a High Density MCU).  I am running the system clock with HSI using PLL, the STM32103xx reference manaual (p.123) states that the max system clock using HSI is 32 MHz but the stm32103rc datasheet (p.52) says shows max HSI being 64MHz.  Does anyone know what the max is for that chip?
2013-10-11T19:52:09 < kevineng963> *36MHz
2013-10-11T19:52:11 < zyp> pretty sure it's 64

2013-10-11T23:56:13 < karlp> sounds like they're giving away the SKUs that no-one has been buying :)

2013-10-12T00:00:43 < karlp> I don't get to go that far looking for things like this,
2013-10-12T00:00:47 < karlp> one day maybe :)
2013-10-12T00:01:05 < karlp> or maybe I just write code that's so bugfree I don't have to go looking for power debugging tools .....
2013-10-12T00:01:13 < karlp> (har har har)
2013-10-12T00:02:52 < karlp> man, adds up, how many grand for keil, then another couple of grand for power tools,
2013-10-12T00:03:00 < karlp> need to make more products that make money I guess :)
2013-10-12T00:03:10 < karlp> or things that run off batteries,
2013-10-12T00:03:22 < karlp> be an easier sell to get power debuggig if we made products for batteries

2013-10-12T00:29:34 < Laurenceb__> http://www.bbc.co.uk/news/magazine-23990211
2013-10-12T00:29:48 < Laurenceb__> "Eighteen months ago in San Francisco, I had another of those rather rare encounters that changes how I think about the world"
2013-10-12T00:32:23 <+Steffan-> Im pretty sure tldr; applies here.
2013-10-12T00:33:54 < Laurenceb__> tldr : 3d printing is da futurreeeeee
2013-10-12T00:38:27 < gxti> if you have to tell people something is changing the world, or worse it is GOING to change the world, the spoilers: it isn't doing shit
2013-10-12T00:39:00 <+Steffan-> gxti is a wise man
2013-10-12T00:39:50 < Laurenceb__> im pretty sure it is doing shit
2013-10-12T00:40:04 < Laurenceb__> but that shit is badly formed plastic pudding shit
2013-10-12T00:40:23 <+Steffan-> The pouder based printers aint that bad ..
2013-10-12T00:40:46 < Laurenceb__> they are too brittle
2013-10-12T00:40:56 < Laurenceb__> the laser metal powder stuff is useful
2013-10-12T00:41:07 < gxti> there are 3d printers that aren't useless but they aren't the ones "makers" are pooping themselves over, they're the 5-6 figure ones that have been in industry all along :p
2013-10-12T00:41:09 < Laurenceb__> but thats not exactly home printer level kit
2013-10-12T00:41:26 <+Steffan-> not yet :)
2013-10-12T00:41:28 < Laurenceb__> yeah we have a stratsys at work
2013-10-12T00:41:28 < gxti> and they aren't replacing "factories", they're prototyping shit so you can make it in a factory
2013-10-12T00:41:35 < Laurenceb__> at cost about £1M
2013-10-12T00:41:42 < Laurenceb__> its barely useful
2013-10-12T00:41:43 < gxti> i guess i was a bit low

2013-10-12T00:42:01 < gxti> you want to get rich, figure out how to make injection moulds cheaper
2013-10-12T00:42:05 < Laurenceb__> i found a use for it last wekk
2013-10-12T00:42:17 < Laurenceb__> vacuum forming molds :P
2013-10-12T00:42:47 < Laurenceb__> the porosity helps
2013-10-12T00:42:52 <+Steffan-> you still didnt show use your fail
2013-10-12T00:43:10 < Laurenceb__> but the vacuum former sometimes gets too hot and melt the molds....
2013-10-12T00:43:33 < Laurenceb__> so I'm going to have to use nylon66 and lathe like a sane person
2013-10-12T00:44:09 < gxti> someday i will have a workshop with a cnc mill
2013-10-12T00:45:08 <+Steffan-> same here.
2013-10-12T00:45:59 <+Steffan-> Have a plan how to do it gxti? Sell more gps-time thingies?
2013-10-12T00:47:22 < gxti> no, i'm not charging nearly enough for that. i could multiply the price by 10 and then maybe businesses would take it seriously :P
2013-10-12T00:47:36 < gxti> day job does an adequate job of financing crap anyway

2013-10-12T00:55:47 < karlp> but sending models to shapeways and getting workable things back in days before going to injection moulding is fucking radical cakes.
2013-10-12T00:55:59 < karlp> but that counts as, "has already changed the world"

2013-10-12T10:49:58 < NooM> :( trolling
2013-10-12T10:50:16 < dongs> asking to ask usually leads to that.

2013-10-12T10:53:25 < dongs> really
2013-10-12T10:53:30 < dongs> on what, OSX or something?
2013-10-12T10:53:34 < NooM> win
2013-10-12T10:53:37 < dongs> why are you using ttf fonts instead of vector
2013-10-12T10:53:42 < NooM> its vector
2013-10-12T10:53:44 < dongs> those will look like crap on actual board
2013-10-12T10:53:48 < dongs> hmmm...
2013-10-12T10:53:54 < NooM> i know, not my first pcb
2013-10-12T10:54:01 < dongs> looks waay dif from my dicktrace renderings
2013-10-12T10:54:38 < dongs> yeah cute crystal placement.
2013-10-12T10:54:45 < NooM> :D
2013-10-12T10:54:55 < dongs> oo. microsd.
2013-10-12T10:54:59 < dongs> you're giving matchboxarm a run for their money.
2013-10-12T10:55:03 < NooM> on the sdio port
2013-10-12T10:55:18 < dongs> only one problem
2013-10-12T10:55:18 < NooM> matchboxwhat ?
2013-10-12T10:55:20 < zyp> your ground plane doesn't look very good
2013-10-12T10:55:23 < dongs> wehre's SWD connector
2013-10-12T10:55:35 < dongs> for you know, getting any work done.
2013-10-12T10:55:37 < NooM> bottom right
2013-10-12T10:56:01 < NooM> i just hook it up with wires to my discovery
2013-10-12T10:56:20 < dongs> you should probly increase ground pour area on top layer.
2013-10-12T10:56:31 < dongs> instead of having like 5mm clearance around it.
2013-10-12T10:56:46 < NooM> its 0.3mm :D
2013-10-12T10:57:06 < dongs> not really sure of utility of writing (configurable) device names as labels instead of PAx PBx etc.
2013-10-12T10:57:19 < dongs> most gpio on F4 is overloaded with liek 2-5 functions
2013-10-12T10:57:21 < zyp> agreed
2013-10-12T10:57:30 < NooM> ya i know, but thats what i wanna play with
2013-10-12T10:57:37 < NooM> its not for sale or so, just for me
2013-10-12T10:57:40 < dongs> oo, i see via in pad
2013-10-12T10:57:43 < zyp> that's what you think you wanna play with
2013-10-12T10:58:09 < zyp> the via in the button pad also looks like a bad idea, but it's probably fine
2013-10-12T10:58:10 < NooM> ya i know via in pad is not that nice, but i guess it will work, there were so few space left
2013-10-12T10:58:31 < zyp> heh
2013-10-12T10:58:41 < zyp> you could just move it up a bit, underneath the button
2013-10-12T10:58:48 < dongs> http://i.imgur.com/W81KJ.png this is what MY dicktrace renderings look like
2013-10-12T10:58:58 < dongs> did oyu just screenshot 3d preview or did you import vrml into something else?
2013-10-12T10:59:01 < dongs> i dont get antialiased shit etc.
2013-10-12T10:59:07 < NooM> 3d screenshot :D

2013-10-12T10:59:53 < zyp> I bet windows is too hardcore for antialiasing
2013-10-12T11:00:03 < NooM> iam using win7
2013-10-12T11:00:04 < dongs> zyp, he said hes using it on windows.

2013-10-12T11:03:33 < dongs> openGL makes nasty shit
2013-10-12T11:03:37 < dongs> directX gives result similar to yours

2013-10-12T11:16:02 < dongs> or SysTick->VAL for micros.

2013-10-12T18:37:47 < Xata> Hello
2013-10-12T18:38:07 <+Steffan-> lo
2013-10-12T18:39:33 < Xata> What is a difference between TIM_ICInitTypeDef, TIM_OCInitTypeDef and TIM_BDTRInitTypeDef? I suppose they are implied for timers with different abilities, but which is for which?
2013-10-12T18:40:08 < karlp> input capture, output compare, not sure about the third
2013-10-12T18:40:36 < Xata> Also st-microelectronics site is unaccessable for me, donno why - looks like routing or server trouble
2013-10-12T18:40:48 < jpa-> bdtr = dead time IIRC
2013-10-12T18:41:04 < jpa-> basically they are all different modes to use the timer
2013-10-12T18:41:11 < karlp> st website doesnt' seem to be a very high priority for st :)
2013-10-12T18:41:26 < jpa-> having things work is not a high priority for st :)
2013-10-12T18:41:38 < karlp> aww, that's harsh :)
2013-10-12T18:41:42 < karlp> they have an irc channel ;)
2013-10-12T18:41:46 < jpa-> :)
2013-10-12T18:45:44 < Xata> karlp: uhuh. thanks.
2013-10-12T18:46:25 < Xata> jpa-: i don't even~ dead time - strange. Anyway i was as close as far. thanks.

2013-10-12T18:48:13 < Xata> Another question just of experience, that i lack - what is the ideal frequency for DMA memory to DAC copy? The fastest, but without copying data before it was converted.
2013-10-12T18:49:23 < jpa-> Xata: the datasheet gives maximum sample rate for DAC (usually like 1MSps)
2013-10-12T18:50:39 < Xata> I have so much questions to ask. Like - if i have TIMx->PSC=19 and TIMx->ARR=49, will i have 8000hz timer? Quartz on dev board is 8mhz
2013-10-12T18:51:09 < jpa-> the quartz goes to a frequency multiplier (PLL) before it is used as the main frequency
2013-10-12T18:51:20 < jpa-> so the frequency depends on your RCC configuration
2013-10-12T18:51:50 < Xata> RCC can have multipliers? woah
2013-10-12T18:51:58 < Xata> rad
2013-10-12T18:51:59 < jpa-> but yeah, if your clock frequency for the timer is 8MHz, then that gives a 8000Hz timer freq
2013-10-12T18:52:35 < Xata> jpa-: nice, and i thought - why my 440hz sine sounds like 220
2013-10-12T18:53:22 < Xata> thanks, got to make all this real and filled up with datasheet
2013-10-12T18:53:49 < emeb_mac> uh-oh. another person doing audio
2013-10-12T18:54:30 < Xata> emeb_mac: but i synthesize it, no tables. just slow, and cycle-hungry double math
2013-10-12T18:54:40 < Xata> that's why 8khz sample rate
2013-10-12T18:55:05 < emeb_mac> whatever floats yer boat.

2013-10-12T18:55:10 < Xata> on the other hand - pesize samples and smooth cycle-to-cycle translation
2013-10-12T18:55:18 < jpa-> Xata: the clock tree in the reference manual is very useful

2013-10-12T18:55:43 < emeb_mac> but one is forced to wonder why use doubles for something that's going to a 12-bit DAC
2013-10-12T18:55:59 < Xata> 8bit is enough
2013-10-12T18:56:29 < Xata> but maybe floats when it will be on optimisation phase
2013-10-12T18:56:54 < emeb_mac> use an M4F and single floats are "free"
2013-10-12T18:57:17  * emeb_mac does audio dsp w/ M4F single floats
2013-10-12T18:58:18 < Xata> emeb_mac: i have only cheap f103vet6 dev board, and no monies in reasonable future for something else. so lets call it proof of concept
2013-10-12T18:59:43 < Xata> hardware is weak, but knowledge is priceless
2013-10-12T18:59:55 < emeb_mac> Xata: got $11? http://www.digikey.com/product-search/en?x=-988&y=-74&lang=en&site=us&KeyWords=497-13192-ND
2013-10-12T19:02:03 < dongs> https://github.com/Crashpilot1000/SGTodaysSnapshot2/blob/master/src/drv_i2c_lcd.c#L431 wow, just wow
2013-10-12T19:03:08 < jpa-> libc is for wimps
2013-10-12T19:03:32 < emeb_mac> that's called "Pro"-gramming
2013-10-12T19:03:33 < dongs> ya sprintf() with formatting is 2 hard
2013-10-12T19:03:42 < dongs> more like Bro-gramming
2013-10-12T19:03:50 < emeb_mac> dude!
2013-10-12T19:04:23 < jpa-> maybe he has some crappy closed-sores sprintf() that doesn't support leading zeros
2013-10-12T19:04:26 < Robint91> I want to personally kill that guy
2013-10-12T19:04:41 < dongs> jpa-: yea, avr-libc
2013-10-12T19:04:42 < jpa-> hmm no, tinyprintf
2013-10-12T19:04:50 < qyx_> ou
2013-10-12T19:04:52 < dongs> (no idea if it doesnt support sprintf with leading zeros. that'd be ridiculous if it didn't
2013-10-12T19:04:54 < qyx_> see hovnokod.cz
2013-10-12T19:05:04 < jpa-> hmm he has tinyprintf there but does not use it :D
2013-10-12T19:05:06 < qyx_> it will fit there exactly
2013-10-12T19:05:16 < jpa-> pretty much anything supports leading zeros, though
2013-10-12T19:05:37 < Robint91> I dunno about trailing zeros?
2013-10-12T19:05:44 < Robint91> is that also configuraable?
2013-10-12T19:06:11 < dongs> .. trailing zeros?
2013-10-12T19:06:19 < dongs> those you know.. change value
2013-10-12T19:06:26 < jpa-> well he is converting an integer to decimal by just slamming a decimal point in the middle
2013-10-12T19:06:46 < dongs> i'm sure same can be achieved by just / 100000 and then %02d'ing the parts
2013-10-12T19:06:48 < dongs> or %08d or whatever.
2013-10-12T19:07:04 < jpa-> could just use    %03d.%08d  
2013-10-12T19:07:06 < dongs> instead of like 20 fucking multiplications/divisions
2013-10-12T19:07:08 < dongs> yeah.
2013-10-12T19:07:11 < jpa-> yeah
2013-10-12T19:07:47 < dongs> that whole file is just incredibly full of fail
2013-10-12T19:07:52 < dongs> including those digitXXXX() functions.
2013-10-12T19:07:58 < jpa-> also.. yeah
2013-10-12T19:08:24 < jpa-> if he had made   digit(x, 10) etc., even the division stuff could look remotely sane
2013-10-12T19:08:50 < jpa-> or even digit(x, 2) so that you wouldn't need to say  1000000000
2013-10-12T19:09:30 < dongs> need to stab hard.

2013-10-13T02:07:01 < qyx_> ipa can do miracles
2013-10-13T02:07:08 < gxti> maybe i can't have usb after all, can't get 48mhz usb clock from 26mhz tcxo let alone the other weirdshit tcxo values out there
2013-10-13T02:07:24 < qyx_> last time i accidentally dissolved lcd backlight in it
2013-10-13T02:07:32 < qyx_> *part of it
2013-10-13T02:08:17 < qyx_> wait what, you are my saviour maybe
2013-10-13T02:08:26 < gxti> not sure if it's worth plopping down a ft230x so i can at least have serial
2013-10-13T02:08:34 < gxti> or just use usb jack for power
2013-10-13T02:08:42 < qyx_> gxti: which tcxo do you have? i want 26mhz for that spirit1 thing
2013-10-13T02:09:13 < gxti> my tcxo spec for this board is "whatever is cheap and in stock at digikey", the part i originally bought already went end-of-life
2013-10-13T02:09:19 < qyx_> i assume it is from dk :S
2013-10-13T02:09:21 < qyx_> ah
2013-10-13T02:10:00 < gxti> when i rewrote everything on top of coos i made the clock switching all in software (not c macros) so it can even autodetect or switch clocks at runtime
2013-10-13T02:10:50 < gxti> it looks like there's still quite a bit of 26mhz in stock, just not as super cheap as the ones i originally got.
2013-10-13T02:11:01 < qyx_> has your ethernet rtt improved?

2013-10-13T02:12:34 < gxti> the problems i was having before were because some chibios debug crap was on that i forgot about, made thread switching awful slow

2013-10-13T02:13:35 < qyx_> on two different boards
2013-10-13T02:14:58 < gxti> got plenty of room on board for a ft230x, i'll just plop down a footprint and decide later whether to populate it

2013-10-13T04:24:55 < qyx_> talsit: try max1555 for example
2013-10-13T04:24:59 < talsit> and if you do have a semi-dead one, won't lock you out until the battery charge rises to usable levels
2013-10-13T04:25:18 < qyx_> or some similar maxim part... i forget exact partno
2013-10-13T04:25:29 < NooM> http://at.mouser.com/Search/ProductDetail.aspx?R=MAX1811ESA+virtualkey66880000virtualkey700-MAX1811ESA
2013-10-13T04:25:32 < NooM> i used this one
2013-10-13T04:25:39 < qyx_> yep, max1811 it was :)
2013-10-13T04:25:42 < NooM> and for discharge, i monitored in software
2013-10-13T04:25:53 < NooM> but with a protected liion you dont have to
2013-10-13T04:26:09 < NooM> they have a small pcb/chip on it that cares about discharge and overcharge
2013-10-13T04:27:03 < NooM> i wanted to charge via solar, but my solar panel is such a crap :D
2013-10-13T04:27:04 < talsit> yep, but if it does go into that overdischarge protection mode, it locks out the lipo until it reaches safe voltages again
2013-10-13T04:27:16 < NooM> if not directly placed to the sun it outputs way too less
2013-10-13T04:27:28 < talsit> i found that, in that case, most lipo/liion chargers will lock you out
2013-10-13T04:27:47 < qyx_> define "lock you out"
2013-10-13T04:27:49 < NooM> i dont know what lockout means in that case
2013-10-13T04:27:52 < qyx_> you still can discharge
2013-10-13T04:27:52 < NooM> haha :D
2013-10-13T04:28:14 < talsit> ok, example:
2013-10-13T04:28:23 < talsit> i'm looking at the TI bq25050
2013-10-13T04:28:28 < NooM> its a simple iC (the max) ... you read the voltage of the li with an analog pin or so
2013-10-13T04:28:30 < talsit> in the datasheet it says: "The LDO output is used to power circuitry such as USB transceivers in dead battery conditions. This
2013-10-13T04:28:30 < talsit> allows the user to operate the product immediately after plugging the adapter in, instead of waiting for the battery

2013-10-13T04:29:40 < qyx_> i can't see any problem
2013-10-13T04:29:48 < qyx_> use reference design from datasheet
2013-10-13T04:29:57 < talsit> if someone leaves my device on, while unplugged, it will draw from the battery until overdischarge
2013-10-13T04:29:59 < NooM> use a diode to protect from damaging
2013-10-13T04:30:04 < NooM> on the positive lines
2013-10-13T04:30:14 < NooM> i mean, theres better option tho, but that will do it
2013-10-13T04:30:21 < talsit> in overdischarge, the lipo will lockout
2013-10-13T04:30:34 < qyx_> no, it will be simply discharged
2013-10-13T04:30:43 < NooM> and than be dead
2013-10-13T04:30:45 < NooM> :D
2013-10-13T04:30:48 < qyx_> bt yes, your device won't have enough voltage to operate
2013-10-13T04:31:15 < NooM> qyx_ the ones with protection on it will turn off
2013-10-13T04:31:22 < NooM> and thats good
2013-10-13T04:31:29 < NooM> otherway youd damage it
2013-10-13T04:31:37 < qyx_> you can use some mosfet magic to switch between external psu and battery
2013-10-13T04:31:42 < talsit> yeah, if it hits that lower discharge threshold, it will lockout
2013-10-13T04:31:49 < qyx_> or dedicated power-oring controllers (ideal diode controller)
2013-10-13T04:31:52 < talsit> until you charge it again
2013-10-13T04:31:55 < qyx_> or charger with aux power input
2013-10-13T04:32:11 < NooM> talsit and thats a good feature, saves you from fire
2013-10-13T04:32:18 < talsit> NooM: i agree
2013-10-13T04:32:27 < qyx_> to be able to use the device with external power supplied when the battery is discharged
2013-10-13T04:32:41 < talsit> now, my problem is that the charge chip (bq25050) will not supply voltage to my device until the battery leaves lockout
2013-10-13T04:33:20 < NooM> get a different charger :D
2013-10-13T04:33:27 < NooM> that max one is good :D
2013-10-13T04:33:51 < talsit> the 1811?
2013-10-13T04:33:57 < talsit> i'll read up on it
2013-10-13T04:33:58 < NooM> ya
2013-10-13T04:34:01 < NooM> and very simple
2013-10-13T04:34:09 < NooM> that why ive choosen it
2013-10-13T04:34:10 < talsit> but that "feautre" seems to be a recurring theme
2013-10-13T04:34:27 < NooM> hmm
2013-10-13T04:35:09 < qyx_> talsit: your charger supports this feature
2013-10-13T04:35:28 < qyx_> The low-battery system startup circuitry maintains
2013-10-13T04:35:28 < qyx_> OUT greater than 3.4V whenever an input source is
2013-10-13T04:35:28 < qyx_> connected. This allows the system to start-up and run
2013-10-13T04:35:28 < qyx_> whenever an input source is connected regardless of
2013-10-13T04:35:28 < qyx_> the battery voltage.
2013-10-13T04:35:31 < qyx_> hop
2013-10-13T04:35:57 < talsit> qyx_: yep, but then, further down: This
2013-10-13T04:35:57 < talsit> allows the user to operate the product immediately after plugging the adapter in, instead of waiting for the battery
2013-10-13T04:35:57 < talsit> to charge to useable levels.
2013-10-13T04:36:13 < talsit> so, i dunno what to think
2013-10-13T04:36:23 < qyx_> but this is what you want, isn't it?
2013-10-13T04:36:41 < NooM> while charging you use the charger as power supply too
2013-10-13T04:36:48 < talsit> qyx_: wait, sorry, that's referring to the 50mA LDO
2013-10-13T04:36:53 < talsit> *just* that part
2013-10-13T04:36:54 < NooM> load connected in parellel with the battery
2013-10-13T04:37:07 < talsit> p17
2013-10-13T04:37:17 < NooM> if you look the max datasheet page 6
2013-10-13T04:37:20 < talsit> under the section for the 50mA LDO
2013-10-13T04:37:42 < qyx_> talsit: ldo is completely unrelated part
2013-10-13T04:37:42 < NooM> or even on the first page
2013-10-13T04:38:36 < talsit> qyx_: it's an different section of the chip, but its wording worries me to the point of confusion
2013-10-13T04:39:10 < talsit> NooM: that 1811 part
2013-10-13T04:39:17 < dongs> dead chats
2013-10-13T04:39:19 < talsit> it says it soft-starts a battery
2013-10-13T04:39:32 < talsit> when near-dead
2013-10-13T04:39:34 < NooM> ya
2013-10-13T04:39:46 < talsit> does it do it in CC or CV mode?
2013-10-13T04:39:53 < NooM> i have no idea :D
2013-10-13T04:40:12 < NooM> i just hooked it up like the schematics on the first page and it worked :D
2013-10-13T04:40:45 < qyx_> talsit: no, ldo is different thing, theres a p-mosfet which allows you to disconnect battery from the load if its voltage is too low, it is described somewhere around page 13 in charging control
2013-10-13T04:42:00 < qyx_> also see Figure 22. Typical Charging Cycle with External Power Path Control Enabled
2013-10-13T04:42:40 < qyx_> system voltage (with load connected) will always be higher than 3.5V and <= ~4.3V
2013-10-13T04:43:14 < talsit> that's what i thought
2013-10-13T04:44:49 < talsit> time to order some samples and test this thing then
2013-10-13T04:47:29 < talsit> last year, i tried using the lipo rider pro for something similar to this, and when the battery was in undervoltage lockout the lipo rider would refused to supply anything
2013-10-13T04:48:25 < talsit> even while connected to a proper supply - i had to wait for the battery to charge up

2013-10-13T05:17:33 < NooM> wohoo finished my nokia5110 lcd driver :D
2013-10-13T05:19:50 < qyx_> any recommended cheap gps module for 1.8V?
2013-10-13T05:20:26 < talsit> a few ublox do operate at 1.8V
2013-10-13T05:22:03 < NooM> http://pastebin.com/dz06QH0F
2013-10-13T05:22:03 < NooM> :D
2013-10-13T05:22:52 < talsit> qyx_: oh, you said "cheap"
2013-10-13T05:23:12 < NooM> you can use a normal cheap one and use a level shifter
2013-10-13T05:23:13 < NooM> :D
2013-10-13T05:25:05 < talsit> qyx_: neo-7m, max-7q, max-7w
2013-10-13T05:25:18 < talsit> err... the max, it's the max-7c
2013-10-13T05:27:04 < qyx_> i also found some quectel ones
2013-10-13T05:27:17 < qyx_> L30, L50
2013-10-13T05:27:21 < qyx_> sirf IV based
2013-10-13T05:32:51 < dongs> qyx_: ublox neo6m is ~10/
2013-10-13T05:33:17 < dongs> duno what your definition of cheap
2013-10-13T05:33:32 < dongs> like talsit-class cheap, then maybe you wanna tear down some old nokia and hookup to its GPS using arduino uno
2013-10-13T05:34:00 < NooM> :D
2013-10-13T05:35:43 < dongs> talsit: im liking jar paste so far. cleanup isnt as bad as I thought, and i bought some plastic spatula shit that I use to stick most of it back into the jar after application.
2013-10-13T05:36:14 < talsit>  i'm very happy with it
2013-10-13T05:36:29 < talsit> i keep a syringe of it near my station that i top up every now and again
2013-10-13T05:36:42 < talsit> i don't do a lot of reflow, so that suits me
2013-10-13T05:36:52 < talsit> and the results of it are pretty good
2013-10-13T05:37:00 < talsit> is it different to what you had before?
2013-10-13T05:37:55 < dongs> no. just jar vs tube
2013-10-13T05:38:39 < talsit> and it's cheaper

2013-10-13T09:48:44 < gxti> no
2013-10-13T09:49:08 < dongs> can't you reuse boot0 as gpio later on
2013-10-13T09:49:11 < dongs> after boot
2013-10-13T09:49:13 < dongs> or is that on F4/F4 only
2013-10-13T09:49:22 < dongs> er f3.f4
2013-10-13T09:49:25 < gxti> on f1 boot0 is not gpio
2013-10-13T09:49:35 < gxti> boot1 is though
2013-10-13T09:49:35 < dongs> it IS somewhere else tho right?
2013-10-13T09:49:43 < dongs> maybe im tihnking boot1

2013-10-13T09:50:12 < dongs> hm no
2013-10-13T09:50:15 < dongs> its dedicated everywhere.
2013-10-13T09:53:42 < talsit> because it seems kinda silly to dedicate a whole button to something that may only be used 1-3 times during the course of tha product's lif
2013-10-13T09:53:44 < talsit> life
2013-10-13T09:54:21 < gxti> talsit: bmp for example not only connects it to a gpio but uses the gpio to pull it high then reset
2013-10-13T09:54:45 < gxti> which is kind of silly when it could just jump to the address where the bootloader lives, but whatever
2013-10-13T09:54:52 < talsit> with a cap or something?
2013-10-13T09:55:00 < talsit> yeah, i'm thinking of doing that
2013-10-13T09:55:01 < gxti> no cap actually, not sure how it works
2013-10-13T09:55:22 < talsit> strange, i would have thought it wouldn't be reliable enough
2013-10-13T09:55:33 < gxti> me neither, maybe i misread.
2013-10-13T09:55:56 < talsit> by "thinking of doing that" i mean jumping directly to bootloader
2013-10-13T09:56:20 < gxti> i haven't tried it before so i can't promise that it works.
2013-10-13T09:56:37 < talsit> jumping directly to bootloader?
2013-10-13T09:56:40 < talsit> why wouldn't it?
2013-10-13T09:57:03 < gxti> because st hates you and wants you to be angry
2013-10-13T09:57:08 < gxti> i dunno
2013-10-13T09:57:12 < talsit> fair enough
2013-10-13T09:57:13 < gxti> just saying, if it doesn't work don't blame me
2013-10-13T09:57:42 < talsit> i wouldn't do that
2013-10-13T09:58:40 < dongs> gxti: lol wut.
2013-10-13T09:58:42 < gxti> oh, bmp thing wasn't boot0 it was a gpio that the (custom) bootloader uses
2013-10-13T09:58:49 < dongs> gxti: yeah i was gonna say
2013-10-13T09:58:56 < dongs> how you gonna pull boot0 AND reboot and keep it pulled.
2013-10-13T09:59:25 < dongs> well i guess it might work but still, wut.
2013-10-13T10:00:22 < gxti> yeah it's just doing a cpu reset
2013-10-13T10:00:30 < gxti> so gpio keeps state

2013-10-13T18:10:31 < englishman> dongs, for rev5 detecting 12mhz xtal, these lines: GPIOC->ODR &= (uint32_t)~(CAN_MCR_RESET);
2013-10-13T18:10:35 < englishman> what are you doing here?
2013-10-13T18:11:03 < englishman> canbus stuff to detect board revision?
2013-10-13T18:11:13 < dongs> englishman: trolling, mostly
2013-10-13T18:11:31 < dongs> englishman: you can't detect HSE mhz on F1.
2013-10-13T18:11:39 < dongs> so dont even try.
2013-10-13T18:13:38 < englishman> ok, but you are doing something there no? as the decision is in the line after
2013-10-13T18:15:18 < englishman> gpioc on qfp48?
2013-10-13T18:19:21 < englishman> so it just runs at 108mhz?

2013-10-13T18:26:08 < englishman> there are 2 revisions of this dongs board, old is 8MHz, new is 12MHz HSE. but the same firmware runs on both, i was checking out how dongs detected it

2013-10-13T18:27:35 < jpa-> hmm.. if you'd run off the 8 MHz HSI, you could have RTC run off HSE/128 and detect the freq, even on F1

2013-10-13T18:28:27 < englishman> tqfp48
2013-10-13T18:28:35 < englishman> so gpioc isn't on pins

2013-10-13T18:30:05 < englishman> yay.
2013-10-13T18:30:18 < englishman> this is how to learn things.
2013-10-13T18:30:42 < dongs> you don't learn much from IOCCC
2013-10-13T18:30:57 < dongs> < jpa-> hmm.. if you'd run off the 8 MHz HSI, you could have RTC run off HSE/128 and detect the freq, even on F1
2013-10-13T18:31:10 < dongs> jpa-: try it
2013-10-13T18:31:38 < jpa-> dongs: can't bother
2013-10-13T18:31:42 < dongs> pfft :(
2013-10-13T18:31:50 < qyx_> we will prove you are wrong!
2013-10-13T18:31:51 < qyx_> one day!
2013-10-13T18:31:53 < qyx_> maybe
2013-10-13T18:32:02 < talsit> isn't that how the F4 does the USB bootloader?
2013-10-13T18:32:20 < talsit> runs off HSI to detect the HSE frequency, then switches
2013-10-13T18:32:32 < dongs> englishman: anyway, don't try to understand. its not doing what you think its doing.
2013-10-13T18:32:53 < englishman> i figure it's a good chance to get gdb working so i can check out what actually happens

2013-10-13T18:33:54 < jpa-> englishman: do the both versions of the board have a 48 pin microcontroller?
2013-10-13T18:33:58 < englishman> yeah
2013-10-13T18:34:05 < jpa-> yeah, then dongs is just trolling
2013-10-13T18:34:09 < englishman> yeah
2013-10-13T18:35:50 < englishman> my best guess is, line 143 evaluates false so it uses pllmull9 and just runs overclocked
2013-10-13T18:36:51 < englishman> hmm i could use a spectrum analyzer to detect which clock freq is actually used
2013-10-13T18:37:19 < jpa-> doesn't it use an usart or anything that you could check?
2013-10-13T18:37:32 < jpa-> or just check DWT cycle count with gdb
2013-10-13T18:37:36 < dongs> its not running overclocked.
2013-10-13T18:37:43 < dongs> englishman: hint, clockspeed is debug[4] in gui

2013-10-13T18:43:20 < englishman> aww my rev1 board died in a crash.
2013-10-13T18:43:26 < dongs> but that doesnt show HSE freq.

2013-10-13T19:09:01 < ASenR> hi, i am a newbee of stm32, i want to develop stm32 program on linux, and using pl2303 chip()
2013-10-13T19:09:17 < ASenR> to download program
2013-10-13T19:09:36 < dongs> "developing" on STM32 generally implies having a proper debugger.
2013-10-13T19:09:44 < dongs> you aren't gonna get very far flashing code via bootloader
2013-10-13T19:09:47 < dongs> thats what arduino guys do.
2013-10-13T19:09:54 < ASenR> but, what driver should i install?
2013-10-13T19:10:24 < dongs> for what? I would imagine, PL2303 driver.
2013-10-13T19:10:33 < PaulFertser> ASenR: none, if you want to use serial bootloader.
2013-10-13T19:10:47 < PaulFertser> ASenR: the kernel comes with pl2303 driver already, and it autoloads it.
2013-10-13T19:11:00 < ASenR> dongs, but i can't find pl2302 driver
2013-10-13T19:11:12 < dongs> i missed the part where you said "lunix"
2013-10-13T19:11:16 < dongs> then it is as PaulFertser said. nothing to do.
2013-10-13T19:11:23 < ASenR> PaulFertser, thx
2013-10-13T19:11:32 < PaulFertser> ASenR: get https://gitorious.org/stm32flash to talk to the bootloader
2013-10-13T19:12:29 < ASenR> so, what program can i use to download progam to stm32?
2013-10-13T19:13:18 < englishman> hmm more fun following RCC_CRH
2013-10-13T19:13:25 < englishman> but still can't see where decision is made
2013-10-13T19:13:36 < PaulFertser> ASenR: just told you :)
2013-10-13T19:13:47 < ASenR> PaulFertser, oh i see it
2013-10-13T19:14:55 < ASenR> PaulFertser, i am in china and the internet is slow... as u can see:)

2013-10-13T19:58:38 < Laurenceb_> seems to have "ChromART" support

2013-10-13T20:01:49 < Laurenceb_> supports comic sans
2013-10-13T20:02:26 < jpa-> doesn't support unicode

2013-10-13T20:02:39 < Laurenceb_> not bad
2013-10-13T20:02:54 < jpa-> hmm maybe actually supports unicode also

2013-10-13T22:31:01 <+Steffan-> lo
2013-10-13T22:32:54 < gxti> this seems like a good idea and a bad idea at the same time: http://partiallystapled.com/~gxti/circuits/2013/10/13-cutout.png
2013-10-13T22:33:45 < Xata> Is here anybody bored enough to look at code listing? I've made some uncommented register porn, so that cpu of uC has to be 72mhz, clocked from pll, that is clocked from external 8mhz clock, upscaled 9 times, all rcc's have a 2 divider. Question is - is everything right? Because sine arpegio of my synth sounds tuned, but pitched off tuning.

2013-10-13T22:46:59 < Xata> or core is clocked from it?
2013-10-13T22:47:22 < jpa-> core is clocked from AHB
2013-10-13T22:47:42 < jpa-> if you look in the clock tree, it says "core" there on the right under "HCLK"
2013-10-13T22:49:52 < Xata> jpa-: no good, but on the hand it means i can at least two times more on uC without glitching sound. God bless arm and stm. on avr i could not do something even close, and several times more costy
2013-10-13T22:50:24 < Xata> *on the other hand
2013-10-13T22:57:05 < Xata> jpa-: so i fixed dat, and now it is two times faster, and pitch is two times higher. This means, that all basic things i want are working, but i have to connect lcd, rot the future. Question is - why my timer began working two times faster, while APB1 clock is got from PLL divison? Or is HCLK is dependant on SYSCLK? What i have to search for in datasheet?
2013-10-13T22:58:03 < gxti> Xata: some timers (don't remember which) run at fAPB * 2 when APB is divided
2013-10-13T22:58:43 < gxti> so you can still run 72mhz timer even though APB1 is 48mhz max
2013-10-13T23:02:01 < Xata> gxti: ok. thanks. last question for now - do speed of rcc's influence cpu performance? i mean what is better - dividing APB1 grequency by 2 or leave it alone and divide timer frequency by increasing TIMx->PSC?
2013-10-13T23:02:55 < gxti> it is better to use the prescaler
2013-10-13T23:03:13 < Xata> gxti: thanks
2013-10-13T23:03:22 < gxti> but remember that APB1 is 36mhz max, so you still have to use /2 on that one
2013-10-13T23:03:38 < Xata> jpa-: thanks you good sir, too
2013-10-13T23:03:58 < Xata> gxti: i meant making it /4
2013-10-13T23:03:58 < gxti> the only reason you would run things at less than max speed is if you were trying to save power
2013-10-13T23:04:51 < Xata> but i don't. if i'll succeed one day, it will be a stationary synth
2013-10-13T23:06:08 < Xata> but i think i'll find something more interesting (e.g. a job at least) by the time i will capable of doing all i want
2013-10-13T23:08:36 < gxti> i hope so too. electronics is challenging without money to get decent tools.

2013-10-14T10:21:52 < emeb_mac> I've had no trouble porting between Keil and gcc/texteditor/gdb
2013-10-14T10:23:09 < R2COM1> its like giving him bmw 650 to drive for a while and then taking back away
2013-10-14T10:23:27 < NooM> :D
2013-10-14T10:24:37 < emeb_mac> nah - not taking it away. saying you can only drive it on one-lane streets in an italian hill-town.
2013-10-14T10:25:32 < R2COM1> so what, isnt it cool
2013-10-14T10:25:49 < R2COM1> he would get some hot italian chicks in the area
2013-10-14T10:26:02 < NooM> lol
2013-10-14T10:26:07 < emeb_mac> maybe. but he can't drive fast.

2013-10-14T10:36:48 < NooM> DMA_InitStructure.DMA_Memory0BaseAddr this doesent need to be set at beginning right? like if i wanted to make a function can can transfere different stuff over spi ?
2013-10-14T10:37:03 < NooM> i could set set it each time the transfer starts?
2013-10-14T10:38:34 < jpa-> of course you can call the init function many times

2013-10-14T10:38:52 < jpa-> or just write to registers directly
2013-10-14T10:39:02 < NooM> ok i cant do that :D
2013-10-14T10:40:34 < dongs> DMA1_Channel5->CMAR = foo
2013-10-14T10:40:56 < dongs> but it better be stopped before you do thtat
2013-10-14T10:41:11 < NooM> ok
2013-10-14T10:41:13 < NooM> thx
2013-10-14T10:41:19 < NooM> soon ready to give it a try
2013-10-14T10:41:42 < NooM> 2306825 update in the main loop now, wonder if it will be more with dma :D
2013-10-14T10:43:38 < dongs> only if you have something else to dowhile its DMAing.
2013-10-14T10:43:45 < dongs> if youre just waitin for DMA_TC then... who cares
2013-10-14T10:45:03 < NooM> it counts upwards meanwhile :D
2013-10-14T10:51:30 < NooM> dongs , dma1_channel5 doesent exists, it tried DMA1_Stream4 instead but theres no cmar
2013-10-14T10:52:17 < jpa-> just look in the header, it's there somewhere
2013-10-14T10:52:37 < jpa-> channel vs. stream is f1 vs. f4
2013-10-14T10:52:52 < NooM> what ?
2013-10-14T10:52:56 < NooM> ok
2013-10-14T10:52:58 < NooM> i see
2013-10-14T10:54:31 < NooM> ahh, its called PAR
2013-10-14T10:55:20 < jpa-> or MAR
2013-10-14T10:55:51 < NooM> M0AR and M1AR i have
2013-10-14T10:56:03 < NooM> (iam using f4, the discovery board)
2013-10-14T10:56:14 < jpa-> ah yeah, the double buffer support
2013-10-14T10:56:36 < dongs> m0ar
2013-10-14T10:57:18 < jpa-> M0AR data, yelled the F4 DMA

2013-10-14T23:52:19 < gxti> zeropointo: the old program counter will be stacked upon entering the interrupt
2013-10-14T23:52:50 < gxti> this is for hardfaults but it will work for any interrupt: https://github.com/mtharp/laureline-firmware/blob/master/lib/hardfault.c
2013-10-14T23:53:16 < gxti> (skip the bit around line 45 though)
2013-10-14T23:53:46 < gxti> 'lr' is the return address i.e. where it was when the interrupt happened
2013-10-14T23:53:51 < zeropointo> thanks gxti i'll give it a try.

2013-10-15T00:31:59 < emeb> ds2 is back
2013-10-15T00:32:04 < emeb> longtime
2013-10-15T00:32:15 < ds2> yes, indeed
2013-10-15T00:32:33 < emeb> haven't seen you on the beagle chls either - keeping busy?
2013-10-15T00:33:27 < ds2> personal stuff
2013-10-15T00:33:34 < ds2> catching up on things right now
2013-10-15T00:34:48 < emeb> seems most of the old beagle gang moved off #beagle to #beagle-pro - got tired of the wave of n00bs that showed up after the new stuff that was introduced a while back.
2013-10-15T00:35:44 < Laurenceb__> next: beagle-pro-pro
2013-10-15T00:35:48 < ds2> hahah

2013-10-15T00:36:00 < emeb> meta-pro
2013-10-15T00:38:10 < ds2> anyone tried dipping in to the Atmel A5 stuff?
2013-10-15T00:38:17 < ds2> i.e SAMA5D31
2013-10-15T00:39:52 < emeb> nope
2013-10-15T00:40:15 < ds2> it seems like a tempting chip for those of us who wants a MMU
2013-10-15T00:40:36 < emeb> run actual linux, not just uclinux

2013-10-15T00:41:12 < emeb> lfbga tho - not extremely diy-friendly.
2013-10-15T00:41:22 < ds2> that isn't too bad
2013-10-15T00:41:32 < ds2> not like the 0.4mm of the AM37x parts
2013-10-15T00:41:38 < emeb> true
2013-10-15T00:42:18 < emeb> lotsa goodies on that chip
2013-10-15T00:42:45 < ds2> 0.8mm pitch too
2013-10-15T00:43:04 < ds2> the biggest attaction is no PMIC required
2013-10-15T00:43:18 < emeb> that's a big plus
2013-10-15T00:43:19 < ds2> uSD/chip/SDRAM and goto town
2013-10-15T00:43:31 < emeb> 18x18 bga grid - ugh
2013-10-15T00:43:40 < emeb> need lotsa layers.
2013-10-15T00:44:20 < ds2> only if you bring out everything
2013-10-15T00:44:28 < emeb> there's that
2013-10-15T00:44:37 < emeb> if you don't need the LCD...
2013-10-15T00:45:02 < ds2> besides, not many MMU enabled options around if you want a reasonable price build in a 30mmx30mm board formfactor
2013-10-15T00:45:20 < emeb> that's a small board
2013-10-15T00:45:24 < ds2> yes
2013-10-15T00:45:40 < ds2> the PMIC on the TI parts kind of kill that unless you do the 0.4mm stuff
2013-10-15T00:45:48 < ds2> then you budget goes out the window
2013-10-15T00:47:12 < emeb> 15x15mm pkg
2013-10-15T00:47:22 < emeb> there's 1/4 of your real estate
2013-10-15T00:47:31 < emeb> how much for DRAM?
2013-10-15T00:48:12 < karlp> 25x35 passable? http://www.asiarf.com/The-Smallest-Tiny-Realtek-802-11n-AP-Router-Module-Board-AWM001-product-view-341.html
2013-10-15T00:50:04 < ds2> whatever fits in 1 chip ;)
2013-10-15T00:50:19 < ds2> 128M might be a good number
2013-10-15T00:50:27 < emeb> what's the supply voltage - not mentioned on the summary ds
2013-10-15T00:50:44 < ds2> karlp: now, tellme how to buy the realtek chip in quantities of 1 along with a datasheet
2013-10-15T00:50:56 < ds2> emeb: 3.3V and down
2013-10-15T00:51:02 < emeb> not bad
2013-10-15T00:51:43 < ds2> it needs to be LiIon powered so it is not prefect. going to have to see if it will tolerate 3.0V and run a mmc card
2013-10-15T00:51:46 < karlp> if you only want one, then I'm sure samples can be arranged
2013-10-15T00:51:57 < emeb> huh - only $15 at DK. and in stock too.
2013-10-15T00:52:01 < ds2> karlp: with realtek? I doubt that
2013-10-15T00:52:15 < karlp> easier than atheros/broadcom
2013-10-15T00:52:57 < emeb> wow - costs come down fast in qty too.
2013-10-15T00:52:59 < ds2> heh
2013-10-15T00:53:26 < ds2> the literature for that part seems to indicate it is directly aimed at the AM33x stuff from TI
2013-10-15T00:53:57 < ds2> karlp: atheros used to be easy. write them a check and it is done.
2013-10-15T00:55:21 < karlp> yeah, well, it's qualcomm now isn' tit :)
2013-10-15T00:56:13 < emeb> ds2: anyone got a cheap devboard for it?
2013-10-15T00:57:20 < ds2> emeb: have not looked that far
2013-10-15T00:57:30 < emeb> not finding any *cheap*
2013-10-15T00:57:47 < emeb> Atmel wants ~$600 for theirs, but it's got lots of extra stuff
2013-10-15T00:57:56 < ds2> they have SOMs

2013-10-15T00:59:38 < emeb> ya - lots of SOMs out there.
2013-10-15T01:00:54 < ds2> I am worried that Amtel might refuse to support users of the chip... they were heavily pushing SOMs when I was at one of their talks
2013-10-15T01:01:53 < karlp> less to support than, "man, my ram don't work good, fixit plz"
2013-10-15T01:02:30 < ds2> heh... you mean like one of those cheap TI dev board fiascos?
2013-10-15T01:02:38 < karlp> ;)
2013-10-15T01:03:04 < karlp> not all SoMs are created equal, some are created by the new hires and people weren't actually meant to buy them

2013-10-15T06:37:15 < upgrdman> i found a youtube video that mentioned integrating a zero if the proportional factor was >100%, to keep the integral part form "winding up". makes perfect sense, but i've never seen it mentioned anywhere else. does it seem right?
2013-10-15T06:38:08 < GargantuaSauce> some implementations just cap the integral at some arbitrary value also

2013-10-15T08:12:23 < gxti> ASenR: the target names (arm-none-whatever) don't tell you anything interesting
2013-10-15T08:17:41 < GargantuaSauce> ASenR: what distro?
2013-10-15T08:17:56 < zippe> ASenR: in general, <processor>-<operating system>-<binary format>
2013-10-15T08:18:09 < GargantuaSauce> if arch, the AUR package arm-none-eabi-gcc48-linaro works well
2013-10-15T08:18:21 < zippe> arm-none-eabi means arm processor, no specific operating system, EABI (ELF ABI)
2013-10-15T08:19:13 < zippe> What you care about more is which specific GCC branch it's built from. The launchpad link above comes directly from ARM, and it's a safe bet.
2013-10-15T08:22:28 < ASenR> GargantuaSauce, arch, u got it :)
2013-10-15T08:22:58 < ASenR> zippe, i've installed arm-none-eabi pkg just now
2013-10-15T08:39:29 < ASenR> R2COM, i don't think so, linux is faster on my poor machine and i can learn more things. XD

2013-10-15T09:02:45 < NooM> yesterday
2013-10-15T09:03:06 < emeb_mac> I got it working on an F3xx a while back
2013-10-15T09:03:11 < NooM> and now i hooked up a bigger display, its around 40kb of screen data i wanna send, so i think dma would really pay of
2013-10-15T09:03:37 < emeb_mac> oh, you're doing a display too.
2013-10-15T09:03:43 < NooM> ya spi one
2013-10-15T09:03:51 < NooM> st7735
2013-10-15T09:03:59 < emeb_mac> ya - I did it from an F373 to one of those adafruit LCDs
2013-10-15T09:04:07 < NooM> ya
2013-10-15T09:04:40 < emeb_mac> the f373 doesn't have 40kB of SRAM so I did it in sections from a smaller bitmap
2013-10-15T09:04:48 < NooM> :D
2013-10-15T09:05:04 < NooM> i have the f4 discovery board

2013-10-15T09:05:25 < NooM> yeah
2013-10-15T09:05:42 < NooM> display is working (kind of portet the adafruit lib)
2013-10-15T09:05:49 < NooM> so now, dma :D
2013-10-15T09:05:52 < emeb_mac> weird thing I found - there was a _lower_ limit on the SPI clock.
2013-10-15T09:06:03 < emeb_mac> wouldn't work unless I was running it fast.
2013-10-15T09:06:06 < NooM> i use clockdiv2 on spi2, so 21mhz
2013-10-15T09:06:15 < emeb_mac> that's about right.
2013-10-15T09:06:24 < NooM> spi2 and 3 cant go faster

2013-10-15T09:27:17 < NooM> nope
2013-10-15T09:27:25 < NooM> all the code i posted is what i used for dma

2013-10-15T10:21:49 < NooM> yeah i know :(
2013-10-15T10:22:10 < dongs> does it work in polled mode?
2013-10-15T10:22:18 < NooM> without dma yes
2013-10-15T10:22:50 < NooM> SPI_I2S_DMACmd(SPI2, SPI_I2S_DMAReq_Tx, ENABLE);
2013-10-15T10:22:55 < NooM> as soon as i call this it locks up
2013-10-15T10:26:50 < NooM> and when i use debug mode it still loops, like it switches from my main loop to the dma stuff
2013-10-15T10:27:10 < NooM> but not calling the function from main loop
2013-10-15T10:27:27 < dongs> locks up?
2013-10-15T10:27:43 < NooM> ya idk what exactly happens
2013-10-15T10:27:44 < dongs> DMA_InitStructure.DMA_Memory0BaseAddr  = (uint32_t)&backbuffer
2013-10-15T10:27:49 < dongs> volatile uint8_t backbuffer[128*160*2];
2013-10-15T10:27:54 < dongs> why are you giving it a pointer to backbuffer
2013-10-15T10:27:57 < dongs> its already a pointer?
2013-10-15T10:28:03 < jpa-> NooM: do you have some kind of handler for hardfault, so that you know if it goes there?
2013-10-15T10:28:20 < NooM> jpa- well theres a standard one, and it doesent land there
2013-10-15T10:28:38 < NooM> dongs thats what the tutorial said, i also tried removing the &
2013-10-15T10:28:46 < jpa-> dongs: &array returns the same as &array[0], which is really the same as array anyway.. don't ask me why
2013-10-15T10:29:28 < GargantuaSauce> does backbuffer need to be aligned to 1024 bytes
2013-10-15T10:29:58 < NooM> how you mean? its a display
2013-10-15T10:30:09 < jpa-> DMA shouldn't care about alignment
2013-10-15T10:30:52 < GargantuaSauce> oh that is burst mode i guess?

2013-10-15T13:27:14 < NooM> 0402
2013-10-15T13:27:35 < zyp> then you want thermals
2013-10-15T13:27:45 < zyp> otherwise you'll get lots of tombstones
2013-10-15T13:27:57 < NooM> now whats that ?
2013-10-15T13:27:58 < zyp> due to one side heating up and melting faster than the other
2013-10-15T13:28:15 < NooM> ahh when the components stand up ?

2013-10-15T13:39:57 < NooM> iam fine with the freeware, dont need 4 layers, too expensive to make
2013-10-15T13:40:10 < NooM> if i need iam gonna upgrade to 500 pins
2013-10-15T13:40:44 < NooM> btw dongs did you notice i got dma to work ?
2013-10-15T13:40:45 < NooM> :D
2013-10-15T13:40:52 < NooM> the faul was somewhere else in my code
2013-10-15T13:40:56 < NooM> ...
2013-10-15T13:41:53 < dongs> right
2013-10-15T13:42:17 < NooM> damn that was stupid, i wasted like 4 hours looking and searching
2013-10-15T13:42:23 < ohsix> you can use cheat engine to bust off something like that pin limit ;D
2013-10-15T13:42:49 < NooM> cheat engine :D
2013-10-15T13:42:56 < NooM> with the memory editor
2013-10-15T13:42:57 < NooM> :D
2013-10-15T13:43:50 < NooM> sadly spi is way too slow for a display, it seems flickering when it updates to the new image
2013-10-15T13:44:12 < NooM> (i mean, 1000 times better than with avr, there i could watch it send the data :D and slowly build up)
2013-10-15T13:45:13 < dongs> um
2013-10-15T13:45:19 < dongs> increase SPI clock speed hten?
2013-10-15T13:45:24 < NooM> its allready max
2013-10-15T13:45:28 < dongs> huh
2013-10-15T13:45:30 < dongs> 42mhz?
2013-10-15T13:45:32 < NooM> 21mhz @ spi2
2013-10-15T13:46:08 < NooM> ya spi1 would be faster, but on my board some of its pins are for the sd card
2013-10-15T13:46:16 < dongs> i serioiusly doubt you can see refresh at 21mhz spi on a 160x128 lcd
2013-10-15T13:46:22 < NooM> sod id better not usem them now and be sad later :D
2013-10-15T13:46:38 < NooM> its 16 bit color
2013-10-15T13:46:42 < NooM> so 40kb data
2013-10-15T13:46:42 < talsit> is that the nokia lcd?
2013-10-15T13:46:47 < NooM> no
2013-10-15T13:46:50 < dongs> https://youtube.com/watch?v=smz2cU3FfFk
2013-10-15T13:46:51 < qyx_> it would be able to refresh 64 times a second
2013-10-15T13:46:54 < dongs> this is SPI 24bit lcd
2013-10-15T13:47:00 < dongs> and at liek 12mhz i think which is lcd's max spec
2013-10-15T13:47:02 < talsit> ah, still, won't have better response than 10ms
2013-10-15T13:47:02 < qyx_> you have probably another bottleneck

2013-10-15T14:04:38 < Laurenceb__> why dont they just use off the shelf active shutter glasses and interleave them with the projector

2013-10-15T15:42:36 < Laurenceb> i guess the retroreflector is quite a good idea
2013-10-15T15:42:45 < Laurenceb> allows use of a dim projector
2013-10-15T15:42:57 < Laurenceb> but i dont see why there are dual projectors on the glasses

2013-10-15T15:44:30 < Laurenceb> that looks epic
2013-10-15T15:45:28 < Laurenceb> also the cast AR thing currently has a huge RFID thingy on solid FR4 under the retroreflector cover

2013-10-15T15:58:28 < Laurenceb> prob ~ 1/3rd the cost
2013-10-15T15:59:31 < Laurenceb> i can haz $400k  ??

2013-10-15T17:28:00 < dongs> We're coming up on a full year since fully funded. Lots of wifi-enabled lightbulbs have hit the market. We are now behind the power curve. Question: How can we make our product cool and advanced agin? My vote, given the app programming is finished, is to officially connect to IFTTT.

2013-10-15T21:07:40 < qyx_> omg totally unconvenient and unusable gui

2013-10-15T21:11:30 <+Steffan-> What qyx_ prefers?
2013-10-15T21:11:33 <+Steffan-> kicad?
2013-10-15T21:11:52 < qyx_> i don't really know, every tool seems unusable to me
2013-10-15T21:12:07 <+Steffan-> heh.
2013-10-15T21:12:52 < gxti> everything is crap
2013-10-15T21:13:02 <+Steffan-> I probably would use dicktrace if it was a native os x/linux app, or kicad if it would work well on os x :P
2013-10-15T21:13:17 < qyx_> diptrace claims to be osx compatible
2013-10-15T21:13:25 < qyx_> they even have an installer
2013-10-15T21:13:30 < gxti> i was going to try diptrace so i can stop pirating altium but now it looks like altium might actually be affordable in the future
2013-10-15T21:13:40 <+Steffan-> iirc it uses wine qyx_
2013-10-15T21:14:11 < qyx_> under linux too
2013-10-15T21:14:23 <+Steffan-> gxti, affordable because it'll be cheaper or because you get enough money for your gps time thingy?
2013-10-15T21:14:36 < gxti> cheaper
2013-10-15T21:14:49 < gxti> no details yet though
2013-10-15T21:14:56 < gxti> could be complete crap
2013-10-15T21:15:06 < qyx_> wine actually adds another level of awesomeness to it
2013-10-15T21:15:15 < qyx_> and gui artifacts
2013-10-15T21:15:23 < gxti> just like kicad!
2013-10-15T21:15:33 < gxti> give that redraw key a workout
2013-10-15T21:19:55 < emeb> diptrace on MacOS works OK.
2013-10-15T21:20:16 < emeb> it does run inside a wine wrapper.
2013-10-15T21:20:23 < zyp> wine isn't that bad
2013-10-15T21:20:39 < zyp> I just tested running usblyzer in wine, seems to work fine apart from the capture driver
2013-10-15T21:20:54 < jpa-> does wine use X11 on mac? because X11 itself on mac seems to be quite buggy already
2013-10-15T21:21:06 < zyp> and that's fine, because I just want to read some captures that somebody else made with it
2013-10-15T21:22:42 < zyp> jpa-, it does
2013-10-15T21:22:42 < emeb> jpa-: haven't seen any huge problems with it using X
2013-10-15T21:22:42 < emeb> "just works"
2013-10-15T21:23:26 < jpa-> yeah, i don't know much about mac but seems that a lot of people complain about X11 on it  "no i don't like gimp because it works like crap on my mac"

2013-10-15T22:50:36 <+dekar> Is anyone using ST's USB stack on the STM32F4? The first 5 prototype boards came in and USB is acting up on two of them. Their DFU bootloader from the ROM works fine though.
2013-10-15T22:51:21 < zyp> acting up how?
2013-10-15T22:53:18 <+dekar> It's really weird, to me it looks like the host gets stuck sending sync sequences - alternating 0's and 1's on the bus.
2013-10-15T22:54:34 < zyp> isn't most digital signals just alternating 0's and 1's? :p
2013-10-15T22:54:45 < zyp> but anyway, how are you checking this?
2013-10-15T22:54:50 <+dekar> I mean literally 010101010101
2013-10-15T22:55:13 <+dekar> Tried some logic analyzer with USB decoding capability, it reports sync and error.
2013-10-15T22:55:37 <+dekar> It seems like the whole enumeration and communication with the command endpoint works fine, but at some point the weirdness starts.
2013-10-15T22:56:54 < zyp> I've seen the peripheral acting up if you mess up fifos or stuff like that
2013-10-15T22:56:57 <+dekar> Funnily the problem only happens on OSX and Windows, on Linux everything is fine and there aren't any errors in dmesg.
2013-10-15T22:58:25 <+dekar> 3 of my boards show no problems on any OS, one acts up all the time and another has about 10% chance.

2013-10-16T00:00:51 < Laurenceb__> i just watched the video
2013-10-16T00:01:16 < Laurenceb__> they developed a fully passive ir tracking system then went for RFID "cuz its cooler"
2013-10-16T00:01:17 < Laurenceb__> wtf
2013-10-16T00:01:43 < Laurenceb__> now it needs a flexipcb active surface to be developed as well....
2013-10-16T00:02:18 < Laurenceb__> which will get broken in no time at all
2013-10-16T00:03:04 < Laurenceb__> also they could drop one of the projectors and halve the cost straight away...
2013-10-16T00:03:07  * Laurenceb__ facepalm
2013-10-16T00:04:20 < Laurenceb__> all because they didnt realise they could talk to 3M and get a custom retroreflective fabric with the right optical properties and a built in IR 2D barcode for a fraction of $400k
2013-10-16T00:05:21 < Laurenceb__> also that would avoid the need for a wand

2013-10-16T00:45:30 < Laurenceb__> but seriously... just add moar projectors
2013-10-16T00:45:38 < Laurenceb__> thats retardo
2013-10-16T00:45:52 < emeb> so do your own? :)
2013-10-16T00:46:12 < Laurenceb__> it is tempting...
2013-10-16T00:46:19 <+Steffan-> it doesn't use two for the 3d effect?

2013-10-16T00:47:07 < Laurenceb__> it uses two for 3d as thats what they tried first
2013-10-16T00:47:20 < Laurenceb__> then it didnt work so they added shutters as well
2013-10-16T00:47:40 < Laurenceb__> so not they have shutter 3D AND dual projector 3D

2013-10-16T03:02:39 < emeb> mine will read from USB flash drive, but only from ones that have high enough read speed.
2013-10-16T03:02:50 < emeb> put in one that's too slow and it complains.

2013-10-16T03:05:07 < emeb> Beats me. I had to buy a bunch of different flashdrives before I found some that worked. PITA

2013-10-16T06:52:11 < emeb_mac> also, I don't start with ADC_Channel_0 - I start with ADC_Channel_1

2013-10-16T07:04:52 < dongs> if I change rank
2013-10-16T07:05:04 < dongs> the channels become something like 4123

2013-10-16T07:05:09 < dongs> instead of 4321
2013-10-16T07:05:11 < dongs> or 1234
2013-10-16T07:06:52 < emeb_mac> weird
2013-10-16T07:07:21 < dongs> @param  Rank: The rank in the regular group sequencer. This parameter must be between 1 to 16.
2013-10-16T07:07:25 < dongs> ...
2013-10-16T07:07:26 < dongs> it only works if rank starts from 0
2013-10-16T07:07:29 < dongs> then tehy're arranged correctly
2013-10-16T07:09:27 < NooM> hey dongs
2013-10-16T07:09:46 < dongs> sup dongs
2013-10-16T07:10:22 < NooM> i tested my display now on spi1 with 42 mhz, i guess its the controller on the display that makes the flickering
2013-10-16T07:10:55 < NooM> ill get me a better display soon, its just a chepo ebay one :D
2013-10-16T07:11:28 < emeb_mac> NooM: get DMA going?
2013-10-16T07:11:34 < NooM> YES
2013-10-16T07:11:41 < emeb_mac> sweeet
2013-10-16T07:11:46 < NooM> i made a stupid mistake
2013-10-16T07:11:54 < NooM> i didnt set the address window for the display
2013-10-16T07:12:01 < emeb_mac> all mistakes are stupid in retrospect.
2013-10-16T07:12:06 < NooM> :D
2013-10-16T07:12:21 < emeb_mac> until you figure them out they're not stupid
2013-10-16T07:12:26 < NooM> haha
2013-10-16T07:12:34 < NooM> i was so focused on the dma stuff
2013-10-16T07:12:39 < NooM> i didnt check the other code
2013-10-16T07:12:46 < emeb_mac> haha
2013-10-16T07:13:27 < NooM> cos in my normal spi code, the make_all_screen_one_color function does set the right address windows for the data allready
2013-10-16T07:13:32 < NooM> but on the dma version i didnt
2013-10-16T07:13:53 < NooM> one thing i also noticed: dma crashes with coocox if you enable optimization
2013-10-16T07:14:03 < NooM> i had to disable code optimization too
2013-10-16T07:15:59 < dongs> hm wtf the adc is totalyl noisy
2013-10-16T07:17:25 < emeb_mac> how noisy?
2013-10-16T07:17:54 < dongs> +- 10 at least
2013-10-16T07:19:46 < dongs> i think im gonna setup DMA_TC interrupt and average a bunch of readings
2013-10-16T07:21:24 < ohsix> you can just pick power vs. 'message' size, the showed the complete conditions for their test and everything implied fromt haat

2013-10-16T08:10:30 < dongs> In case of such emergency, you can borrow someone else's smart phone, log into BitLock application on their phone using your own credentials to lock/unlock BitLock. Your BitLock key is stored in the cloud and can be retreived once you successfully log into BitLock application on any phone.
2013-10-16T08:12:27 < dongs> Is there a subscription fee to use BitLock?
2013-10-16T08:12:28 < dongs> There will be no subscription fees associated with BitLocks pledged by Kickstarter backers.

2013-10-16T10:44:47 < jpa-> yeah, it's not a complex device
2013-10-16T10:46:07 < jpa-> the software side is probably the key; currently it is quite much a pain to edit those images, as batch editing functionality in e.g. gimp is crap

2013-10-16T10:53:23 < jpa-> i wonder if there is any good software for "subtract this background from this set of images".. it would have to be smart enough to detect where the background transitions to the object, handle shadows etc.

2013-10-16T11:31:29 < dongs> oh lame
2013-10-16T11:31:39 < dongs> i thought it was literally something useful like 4 STM32's on one board
2013-10-16T11:31:42 < dongs> but this is just lunix bullshit
2013-10-16T11:32:14 < jpa-> would 4 STM32's really be all that useful?
2013-10-16T11:32:22 < dongs> </sarcasm>
2013-10-16T11:32:26 < jpa-> ah :)
2013-10-16T11:33:04 < GargantuaSauce> i am thinking an f4 and an f0 for a future design since there's only two dma channels
2013-10-16T11:33:04 < GargantuaSauce> long shot from four though
2013-10-16T11:34:12 < jpa-> yep, may make perfect sense in some designs, but these arduino dudes can barely handle even one processor :)
2013-10-16T11:35:32 < GargantuaSauce> my favourite indicator is the fact that the stepper library's step function BLOCKS
2013-10-16T11:36:04 < dongs> lol
2013-10-16T11:36:10 < dongs> WHAT IF YOU WANNA STEP 2 SHITS AT ONCE???
2013-10-16T11:36:33 < GargantuaSauce> then you find another blog post to copypaste code from
2013-10-16T11:39:39 < trepidaciousMBR> I wish Arduino had used an STM32F4 for the Due, rather than some overpriced, underpowered Atmel chip :(
2013-10-16T11:40:03 < GargantuaSauce> even the f1 would have blown it out of the water
2013-10-16T11:40:26 < GargantuaSauce> the maker market sure would look different if that'd happened and the library leveraged its peripherals properly
2013-10-16T11:41:24 < GargantuaSauce> oh there's actually a 'due' now, thought you meant the duemilanove
2013-10-16T11:41:49 < GargantuaSauce> hah non 5v tolerant pins
2013-10-16T11:42:35 < jpa-> GargantuaSauce: well.. i can see that they would prefer atmel because ST is not exactly friendly to open source
2013-10-16T11:42:42 < dongs> a?
2013-10-16T11:42:55 < dongs> how is atmel friendlier to opensores
2013-10-16T11:43:05 < dongs> than any other manufacturer whodoesnt give a fuck about hobby market?
2013-10-16T11:43:44 < jpa-> dongs: atmel seems to actually give a fuck about hobby market; and they help the avr-gcc project, making it less crappy
2013-10-16T11:44:13 < jpa-> compare to ST, whose stm32fxxx.h headers even are non-free if you read the license
2013-10-16T11:45:54 < GargantuaSauce> yeah the whole avr-gcc experience is definitely a bit more streamlined
2013-10-16T11:46:38 < jpa-> not sure how well atmel's tools work for their cortex-m3 offering
2013-10-16T11:46:39 < GargantuaSauce> if only because the set of peripherals is not decoupled from the core architecture so they can include device-specific headers

2013-10-16T15:07:32 < ashfaq> Hi
2013-10-16T15:08:05 < ashfaq> i am planning to start working with stm32 I was wondering if there was a development environment for linux
2013-10-16T15:08:18 < dongs> no, in lunix you only have emacs and gdb
2013-10-16T15:08:54 < ashfaq> anywhere i can find documentation for it?
2013-10-16T15:08:56 <+Steffan-> Use your standard environment ashfaq?
2013-10-16T15:09:20 <+Steffan-> + https://launchpad.net/gcc-arm-embedded
2013-10-16T15:09:56 < ashfaq> yes, the compilers and fine, i was more interested in debugging options with linux
2013-10-16T15:10:18 < ashfaq> gdb is good, but something like keil would help in development time
2013-10-16T15:10:30 < dongs> then dont use lunix.
2013-10-16T15:11:17 < ashfaq> hmm not quite an option for me, its quite expensive since im working on a hobby project
2013-10-16T15:11:30 < dongs> then use free 32k version of keil.
2013-10-16T15:12:55 < ashfaq> im more looking out for linux, as development on linux is much better and im used to this and not windows. 32k version is what I have tried
2013-10-16T15:13:04 < dongs> "much better"
2013-10-16T15:13:10 < dongs> if you already know its much better why not fucking use it then?
2013-10-16T15:13:20 < ashfaq> but was looking for somthing more on the linux end
2013-10-16T15:13:23 < dongs> if your idea of "better development" is editing files in equivalent of notepad.exe then sure
2013-10-16T15:13:30 < dongs> knock yourself out
2013-10-16T15:13:45 < dongs> eclipse is probably about the only thing you're ognna get
2013-10-16T15:13:50 < dongs> but that would require running lunix on an actual desktop

2013-10-16T15:16:43 < dongs> bullshit. you write the code.
2013-10-16T15:16:56 < ashfaq> I run linux and not windows so that isnt a problem
2013-10-16T15:17:58 < ashfaq> yes i write the code, but there is also the part when you interface with the computer wher eyou need more easy access to driver codes which windows doesnt give
2013-10-16T15:19:54 < dongs> sounds like bullshit to me.
2013-10-16T15:20:42 < ashfaq> guess you havnt tried working on linux
2013-10-16T15:22:07 < dongs> because windows suits me just fine.
2013-10-16T15:22:13 < dongs> and I have no problems wiht "driver codes"

2013-10-16T17:21:45 < NooM> hello
2013-10-16T17:22:35 <+Steffan-> Lo
2013-10-16T17:23:37 < NooM> so, iam ordering parts for my board. i planned to use an 8mhz crystal (like the stm32f4 discovery) - but sadly the ones small enought to fit are only 16 and 25 mhz, could that lead to any problems?
2013-10-16T17:23:54 < NooM> or not reaching 168mhz? (cant be divided by 16 and 25 ..?)
2013-10-16T17:35:52 -!- Activate_for_mor [~mirggi@213.87.132.22] has joined ##stm32
2013-10-16T17:36:09 <+Steffan-> 16MHz should be a problem. As you can use the PLL to generate the system clock.
2013-10-16T17:36:21 <+Steffan-> *shouldn't :)
2013-10-16T17:37:41 < NooM> hmm ok, thx
2013-10-16T17:37:43 <+Steffan-> *still use
2013-10-16T17:38:08 < NooM> sounds more complex, maybe i can squeeze in a bigger crystal
2013-10-16T17:38:09 < NooM> :D
2013-10-16T17:39:17 <+Steffan-> Why it should more complex?
2013-10-16T17:39:41 <+Steffan-> *sounds
2013-10-16T17:39:49 < NooM> idk :D
2013-10-16T17:39:51 <+Steffan-> Man, i should read what i write before i press enter :P
2013-10-16T17:41:21 < NooM> cos i have no idea how todo that

2013-10-16T17:46:33 < NooM> iam still noob with stm
2013-10-16T17:46:53 <+Steffan-> How did you expect to generate the 168MHz using the 8MHz xtal?
2013-10-16T17:47:20 < NooM> using all the standard setting coocox maes for me and only changing 2 variables in code :D
2013-10-16T17:47:25 < NooM> makes*
2013-10-16T17:47:30 <+Steffan-> heh
2013-10-16T17:47:55 < NooM> that worked :D
2013-10-16T17:47:56 <+Steffan-> ST does have this excel to how to setup the clock stuff. I've never tried it, so i dont know how useful it is
2013-10-16T17:48:09 <+Steffan-> *excel sheet tool thing.
2013-10-16T17:48:25 < NooM> wanna see my design ?

2013-10-16T17:49:21 < NooM> its for breadboard, it sill leaves space for 2 pins each side
2013-10-16T17:49:23 < NooM> :D
2013-10-16T17:49:44 < NooM> gonna order it today, from itead
2013-10-16T17:49:56 < NooM> picked all the parts from mouser now
2013-10-16T17:50:04 <+Steffan-> You were this guy who actually named some pin functions instead of just the pin name :P
2013-10-16T17:50:11 < NooM> yes
2013-10-16T17:50:14 < NooM> and i still have
2013-10-16T17:50:24 < NooM> i2c i use in any case
2013-10-16T17:50:35 < NooM> spi 1 and 2 too
2013-10-16T17:50:53 <+Steffan-> You're going to regret that.
2013-10-16T17:51:21 < NooM> if i wanna use different functions i can still look what else its connected too
2013-10-16T17:51:38 < NooM> if id name it just pa1 .. and so on id still have to look :D

2013-10-16T17:59:09 < NooM> the libs iam writing are using this pinout allready
2013-10-16T17:59:16 < NooM> so i dont have to think later
2013-10-16T17:59:49 <+Steffan-> It's not a 'universal' breakout board?
2013-10-16T17:59:57 < NooM> nah its only for me

2013-10-16T18:01:03 < NooM> and i wanted to try a bit a better uC :D
2013-10-16T18:01:09 < NooM> and damn stm32f4 is fast :D

2013-10-16T18:02:54 < NooM> i also made an enc28j60 boards
2013-10-16T18:03:02 < NooM> but iam still waiting for the magjacks
2013-10-16T18:03:05 < NooM> the uC works at least
2013-10-16T18:03:26 <+Steffan-> enc28j60 meh :P

2013-10-16T18:03:34 < NooM> indeed
2013-10-16T18:03:45 < NooM> ive started writing a network stack for it
2013-10-16T18:03:49 <+Steffan-> Just the idea it's only 10MBit ;)
2013-10-16T18:03:50 < NooM> but got annoy pretty fast

2013-10-16T18:05:03 < NooM> (tested with the china breakouts)
2013-10-16T18:05:34 < NooM> maybe i make one day a stm32f4 with the ehternet
2013-10-16T18:05:41 < NooM> than iam gonna use the lwip port :D
2013-10-16T18:05:43 <+Steffan-> Be happy this d o n g s guy is not around. He would totally start  about AVRs being obsoleted by cheaper ARMs with more peripherals :P
2013-10-16T18:05:58 < NooM> id agree with him
2013-10-16T18:06:02 < NooM> but thats how i started
2013-10-16T18:06:08 < NooM> i dont feel ashamed :D
2013-10-16T18:07:12 <+Steffan-> I think i actually found this channel because someone mentioned it in #avr

2013-10-16T18:08:26 < NooM> but the core libs from arduino cos they make life easy :D

2013-10-16T18:23:51 < gxti> that would be the smart way to do it

2013-10-16T18:25:19 < gxti> for license reasons mostly
2013-10-16T18:25:31 <+Steffan-> ( a good reason )
2013-10-16T18:26:27 < gxti> coos is kinda crappy though, works but the code quality is poor. but now i'm not relying on anyone's peripheral drivers so changing rtos again would be trivial.

2013-10-16T22:20:53 < karlp> yeah, this has come up before,
2013-10-16T22:21:32 < karlp> there's something where if you write a bigger value to it, it transfers more, even if you weren't planning on it, I don't remember the rest of the details,
2013-10-16T22:21:45 < karlp> zyp saw something like this iirc
2013-10-16T22:24:23 < bsdfox> karlp, perhaps it's adjusting because I'm using a 16 bit integer? even though the value is 8 bit
2013-10-16T22:25:26 < bsdfox> using char z; doesn't seem to make any difference

2013-10-16T22:29:41 <+Steffan-> the paramenter is also int.. not forgot that one bsdfox? ( too obvious maybe )
2013-10-16T22:30:56 < bsdfox> I did forget that but still didn't fix the problem :)
2013-10-16T22:34:03 < bsdfox> -O1 and -Os both exhibit the same behavior :\
2013-10-16T22:34:10 < karlp> yeah, it's the peripheral,
2013-10-16T22:34:19 < karlp> this only happens on the "non F1" iirc
2013-10-16T22:35:20 < bsdfox> is there a workaround? when I change the data size to 7 I get 14 clocks, ds=4 I get 8 clocks
2013-10-16T22:39:24 < bsdfox> when ds = 8, I get 9 clocks, ds=9 I get 10 clocks.. ds=15 I get 16 clocks.. so it seems to only be erratic at ds < 8 (8bit or lower)
2013-10-16T22:49:04 < zyp> I've observed it on F3, not on F4
2013-10-16T22:49:17 < zyp> it's part of the new FIFO stuff in F3, I don't know if F0 also has that
2013-10-16T22:50:28 < zyp> but it sounds like you have the same problem
2013-10-16T22:51:14 < zyp> anyway, the solution is making the register definition a uint8_t so the compiler will emit a 8-bit store instead of a 32-bit store
2013-10-16T22:51:56 < zyp> because stores larger than 8-bit for word sizes <= 8 gets interpreted as two words

2013-10-16T23:17:51 < bsdfox> only port a and b have multiple alternate functions so no need for the AFR register on the others

2013-10-17T16:42:22 < karlp> depends where you want printf to go to :)
2013-10-17T16:42:34 < karlp> you can link with rdimon.specs and use semihosting,
2013-10-17T16:42:44 < karlp> or yes, you would need some stubs to send it to a uart or something else

2013-10-17T16:51:42 < karlp> you really only need _write normally.
2013-10-17T16:52:18 < karlp> such as in https://github.com/libopencm3/libopencm3-examples/blob/master/examples/stm32/f1/stm32vl-discovery/adc-dac-printf/adc-dac-printf.c
2013-10-17T16:52:45 < NooM> hmm
2013-10-17T16:52:53 < fbs> well most return directly anyway
2013-10-17T16:53:03 < fbs> i might need some time & read functions in the future
2013-10-17T16:53:09 < NooM> is this about formating, like printf("i", some_integer); ?
2013-10-17T16:53:30 < fbs> i need to log 'time:temp1:temp2:...:P:power1'
2013-10-17T16:53:41 < fbs> NooM: that would be %d

2013-10-17T16:54:02 < NooM> iam using that
2013-10-17T16:54:56 <+Steffan-> Just curious, why that class is called UART6 ?
2013-10-17T16:55:19 < NooM> cos i made a class for each uart port, and a base class that handles transfers
2013-10-17T16:55:21 < NooM> :D
2013-10-17T16:55:27 <+Steffan-> You also have UART[1..5
2013-10-17T16:55:27 <+Steffan-> ] ?
2013-10-17T16:55:27 <+Steffan-> *0
2013-10-17T16:55:34 < NooM> well, right now only port6 :D
2013-10-17T16:55:40 < NooM> but sooner or later i will have
2013-10-17T16:55:42 < NooM> yesw
2013-10-17T16:55:47 < NooM> uart1,2 and so on
2013-10-17T16:56:15 < NooM> :(
2013-10-17T16:57:07 < NooM> i really have to put that va_list stuff into the base class
2013-10-17T16:57:27 < fbs> why not just make a class 'uart' and 'uart.read(UART6)'
2013-10-17T16:58:29 < NooM> idk :D
2013-10-17T16:59:14 < NooM> i could, but than i would need to make initializers for each,, like uart.init6(); uart.init2();
2013-10-17T16:59:22 < NooM> (i dont want em all at the same time)
2013-10-17T17:01:06 <+Steffan-> No you don't NooM
2013-10-17T17:01:07 <+Steffan-> did you see how zyp did it?
2013-10-17T17:01:24 < NooM> yes
2013-10-17T17:01:48 < NooM> ya maybe i reorganize it :D
2013-10-17T17:04:10 <+Steffan-> arduino style ftw :P
2013-10-17T17:04:33 < NooM> :D
2013-10-17T17:04:48 < NooM> i even cloned the arduino ringbuffer for my uart :P
2013-10-17T17:04:54 < NooM> its interrupt driven too
2013-10-17T17:05:14 < NooM> ok, sending is, ni didnt cared to implement recieving so far
2013-10-17T17:05:23 < NooM> spi was more important to me
2013-10-17T17:06:16 <+Steffan-> ;)
2013-10-17T17:17:44 < NooM> :D iam allready planning my next board :D
2013-10-17T17:18:17 < NooM> if that small one works as expected ill make a bigger one with ethernet and display

2013-10-18T00:18:45 < Laurenceb_> i just realised the photos are mock ups

2013-10-18T00:22:40 < Laurenceb_> most are
2013-10-18T00:24:00 < fbs> scams or just failed underestimated attempts?

2013-10-18T01:09:01 < emeb> Some people go on expensive vacations, some people buy drugs...
2013-10-18T01:09:11 <+Steffan-> Maybe it will even turn out to be something useful, not technically perfect, but useful.
2013-10-18T01:09:31 < emeb> At the very least 2000+ people will have learned something.
2013-10-18T01:09:36 <+Steffan-> :)
2013-10-18T01:09:51 < BrainDamage> kickstarter for dyi meth lab kits
2013-10-18T01:10:05 < BrainDamage> suddendly people cannot spend money on whatever they want anymore
2013-10-18T01:10:37 < emeb> then they can spend money on lawyers.
2013-10-18T01:11:13 <+Steffan-> And they call me a party pooper BrainDamage... :P
2013-10-18T01:11:14 < Laurenceb_> in the terms and conditions most stuff seems to be banned on KS
2013-10-18T01:11:37 < Laurenceb_> and most of the stuff on there is already banned
2013-10-18T01:12:24 < BrainDamage> time to start arduino-only kickstarter then. end the tedious refining process that selectively weeds out the rest
2013-10-18T01:12:49 < Laurenceb_> i have zero confidence that jeri and co can make those glasses at the size and prices they are claiming
2013-10-18T01:12:57 < Laurenceb_> and the fact the video is a mock up....
2013-10-18T01:13:21 < Laurenceb_> and the prototype is using gutted off the shelf pico projectors...
2013-10-18T01:16:05 <+Steffan-> It's funny how it seems you're almost offended by a ks project. Or is that just because you think they screw you over?
2013-10-18T01:16:24 < Laurenceb_> they seem to be scamming people

2013-10-18T01:31:39 < Laurenceb_> lol
2013-10-18T01:31:51 < gxti> (spoilers: it's just a brushless motor)
2013-10-18T01:31:58 < gxti> (but everyone here knew that already)
2013-10-18T01:32:44 <+Steffan-> What about the harmful radio waves gxti?
2013-10-18T01:33:28 < gxti> well it has no electromagnetic radiation, because you control it with an iphone app
2013-10-18T01:34:45 <+Steffan-> :P
2013-10-18T01:37:55 < BrainDamage> you just magically set c=0, and voilà, whole electromagnetism falls apart

2013-10-18T13:20:13 < dongs> still nothing
2013-10-18T13:20:17 < dongs> i wonder if they fucked something up
2013-10-18T13:20:24 < dongs> it doesnt take a month to pcba 200 boards
2013-10-18T13:21:07 < karlp> I think it looks vaguely interesting,
2013-10-18T13:21:21 < karlp> the single toolchain is annoying, but at least it runs on win/mac/linux
2013-10-18T13:21:28 < GargantuaSauce> the complete and utter lack of peripherals is the kicker for me

2013-10-18T13:23:53 < zyp> it's 500 mips, but only if you have at least four threads that's doing something useful at any time
2013-10-18T13:24:11 < zyp> because each thread can't run for more than 1/4 duty, IIRC

2013-10-18T13:25:44 < dongs> i expected it to be something like $25
2013-10-18T13:25:48 < dongs> still useless.

2013-10-18T17:43:17 < trepidaciousMBR> Just wait for Apple's version of the smart watch, they'll do it right, everyone will say it's crap, 5 billion people will buy it, then everyone else will copy it over the next 2-3 years with less restrictive software but more shiny shiny plastic, then finally Google will make a Nexus watch and all will be fine.
2013-10-18T17:44:23 < trepidaciousMBR> fbs: pullDOWN? I'm pretty sure it should be a pullup at least on the clock and data, the CS might need a pullup, depends on the master really.
2013-10-18T17:44:49 < trepidaciousMBR> fbs: Normally an external pullup, but the MCU pullup might do it
2013-10-18T17:45:45 < trepidaciousMBR> fbs: Have you checked the ST reference manual for the MCU, I think it describes the NSS function there?
2013-10-18T17:52:18 < fbs> trepidaciousMBR: in 26.3.6
2013-10-18T17:52:30 < fbs> 1. write proper gpio registers: configure GPIO for mosi, miso, sck

2013-10-18T20:38:41 < bsdfox> obviously it doesn't do much right now (just reads 1 char then sends it out the uart) and should check flags in the interrupt handler but the register setup works
2013-10-18T20:38:41 < fbs> cool
2013-10-18T20:38:45 < fbs> i had some weird errors
2013-10-18T20:38:57 < fbs> i think the code was mostly correct
2013-10-18T20:39:36 < bsdfox> I just fixed the comments on it.. hopefully no silly typos that make it not compile or soemthing silly

2013-10-20T12:03:25 < shiftplusone> Hello, I am a little confused about "TIM2_IRQHandler" does that get triggered on every counter increment or only on autoreload?
2013-10-20T12:05:00 < jpa-> shiftplusone: on autoreload, or if you configure separately, also on capture/compare events
2013-10-20T12:05:52 < shiftplusone> jpa-, thanks. What do you mean by configure separately?
2013-10-20T12:06:36 < jpa-> "TIMx interrupt enable register (TIMx_DIER)"
2013-10-20T12:07:04 < jpa-> in fact, even the update interrupt (which means interrupt on reload) has to be separately enabled
2013-10-20T12:07:42 < shiftplusone> Hm, a little lost. Think I need to jump back into the manual.

2013-10-20T15:01:19 < jpa-> dongs: only on overflow usually; but i guess you could configure it in some fun way to get interrupt every time
2013-10-20T15:01:36 < jpa-> though if you just get an interrupt every time, you might just as well use EXTI
2013-10-20T15:05:24 < dongs> right.
2013-10-20T15:05:39 < dongs> or just A/B gpio in a loop
2013-10-20T15:05:40 < dongs> and compare previous stae.
2013-10-20T15:05:41 < dongs> state.
2013-10-20T15:06:14 < jpa-> but debouncing may be necessary in some cases
2013-10-20T15:06:49 < jpa-> which might be easier to do with the timer.. it has some filtering stuff IIRC, and in any case you could periodically poll the count and only react once it is stable

2013-10-20T19:12:24 <+dekar_> dongs, it's not even related to how much is in my case, I just like the look. I mean you also have a scope for multi line if(), and due to the need for break; cases are multi line most of the time. To me it seems more consistent and thus I prefer it.
2013-10-20T19:15:20 < jpa-> the {} in case doesn't really close it, because you still need the break anyway
2013-10-20T19:15:56 <+dekar_> ofc, my preference is purely visual ;)
2013-10-20T19:17:35 <+dekar_> I mean you usually indent the case anyway, {} just make it even more notable.

2013-10-21T00:39:25 < mervaka> dongs: was just interested in NXP because it's a dual core device, and I was particularly interested in the SGPIO :p
2013-10-21T00:40:16 < mervaka> seems like the only way to get TDM audio into an ARM device
2013-10-21T00:45:23 < zyp> TDM audio?
2013-10-21T00:46:06 < zyp> RM0090 claims that the SAI in F42x supports TDM, whatever that is
2013-10-21T00:47:26 < zyp> ah, fsync/sclk/sdata
2013-10-21T01:07:25 < emeb> interesting problem: I generate audio via DMA-buffered I2S, so the processing takes place "non-realtime".
2013-10-21T01:07:59 < emeb> ie 32 samples of data generated for the next buffer, but generation is about 5-10x faster than the output rate.
2013-10-21T01:08:51 < emeb> I want to react to external events at roughly a "realtime" rate though (sync an oscillator). Need to run a counter to track this at the sample rate.
2013-10-21T01:09:20 < emeb> so question is: wouldn't it be easy to just read the DMA pointer when the even occurs and use that as a rough time index?
2013-10-21T01:10:53 < zyp> that's what I did when I played with usb audio flow control
2013-10-21T01:11:36 < emeb> seems like it'd be a lot easier than trying to sync a timer to the DMA rate.
2013-10-21T01:12:54 < zyp> hmm, depends
2013-10-21T01:13:13 < zyp> if you use a timer, you could use input capture to get precise timing
2013-10-21T01:13:25 < zyp> as long as you get a sane clock input for the timer
2013-10-21T01:14:01 < zyp> like looping back the i2s clock to the timer input
2013-10-21T01:14:22 < emeb> yeah - the I2S frame clock could do that.
2013-10-21T01:14:22 < zyp> then you just set up the timer before starting i2s
2013-10-21T01:14:44 < zyp> is there any possibility of routing the i2s frame clock internally?
2013-10-21T01:15:02 < emeb> I'd be really surprised if so.
2013-10-21T01:15:27 < emeb> this is on an F303
2013-10-21T01:18:32 < emeb> Doesn't look like either the bitclock or wordclock are available anywhere except the specific pins that they drive.

2013-10-21T01:25:20 < mervaka> zyp: SAI looks interesting, not seen this before
2013-10-21T01:25:34 < zyp> that's because it's new
2013-10-21T01:26:05 < emeb> brand new on the F42x/F43x
2013-10-21T01:26:37 < zyp> hmm
2013-10-21T01:26:53 < zyp> any of you done anything fun with F429-discovery yet?
2013-10-21T01:27:21 < mervaka> not even heard of it until now ;/
2013-10-21T01:27:38 < zyp> man, you're not keeping up with the times :p
2013-10-21T01:27:47 < mervaka> heh
2013-10-21T01:27:50 < mervaka> no i haven't
2013-10-21T01:28:14 < mervaka> been dicking about with M3s at work
2013-10-21T01:28:32 < mervaka> and more recently some very abstracted code
2013-10-21T01:28:35 < Laurenceb_> signofthetimes.net
2013-10-21T01:29:07 < mervaka> for my own projects though, the SAI looks very interesting!

2013-10-21T01:42:35 < mervaka> thanks loads zyp, saved me the ballache of learning SGPIO :p
2013-10-21T01:42:38 < mervaka> nn
2013-10-21T01:43:11 < zyp> the sct/sgpio stuff still looks pretty interesting
2013-10-21T01:43:47 < emeb> I've turned on my F429 Discovery! Cute GUI.
2013-10-21T01:44:18 < zyp> I need to get one
2013-10-21T01:44:19 < emeb> Actually, thinking about building a daughter board with various audio I/O stuff on it.
2013-10-21T01:44:38 < zyp> will probably pick up next time I need anything else from DK
2013-10-21T01:48:04 < emeb> 74MB of software bundled up for it - hopefully full source for that GUI app.

2013-10-21T09:05:39 < shiftplusone> I am starting to suspect my approach is stupid. If I need to measure the time between two events (in units of ~123156th of a second), what's the best way to go. Right now I am trying to use a timer and count the ticks then go from there. Is there a way without a timer?
2013-10-21T09:06:24 < jpa-> shiftplusone: use timer and input capture
2013-10-21T09:06:53 < jpa-> i assume "events" come from external IO pins?
2013-10-21T09:07:08 < shiftplusone> yeah, a rising edge
2013-10-21T09:07:34 < jpa-> yeah, input capture is designed for stuff like that
2013-10-21T09:08:18 < shiftplusone> I'll look into it, thanks
2013-10-21T09:08:23 < jpa-> your funny frequency will cause some complication.. i would run the timer at full CPU speed and divide afterwards, but you'll probably need a 32bit timer in that case
2013-10-21T09:08:25 < PaulFertser> R2COM: PHP is a terrible language, ASP.NET locks you in to windows platform and more expensive hostings.
2013-10-21T09:09:11 < PaulFertser> R2COM: probably Python/Django might be a nice alternative for you.
2013-10-21T09:09:30 < PaulFertser> Of course, there're some fancy Haskell frameworks such as Yesod and HappStack :)
2013-10-21T09:11:23 < PaulFertser> Yes
2013-10-21T09:12:16 < shiftplusone> R2COM, is this for production or just testing? I can give you access to a VPS if it's just for messing around.
2013-10-21T09:12:17 < PaulFertser> For me http://me.veekun.com/blog/2012/04/09/php-a-fractal-of-bad-design/ was enough to decide that PHP is not worth it. I'd choose ASP.NET even, PHP is too sick :/
2013-10-21T09:13:31 < shiftplusone> Alright, well if you need it let me now. Right now it's going to waste.
2013-10-21T09:14:13 < shiftplusone> linode... right now just running a mostly abandoned wordpress site.
2013-10-21T09:14:57 < shiftplusone> That's the host, yes. The site is xecdesign.com
2013-10-21T09:16:05 < shiftplusone> yeah, but I've had nothing but trouble with cheap shared hosting.
2013-10-21T09:17:09 < shiftplusone> Many larger sites do end up moving away from php after a while.
2013-10-21T09:17:20 < PaulFertser> R2COM: millions of monkeys can't be wrong, right? :) I honestly have an impression the vast majority of PHP code was written by incompetent developers without any insight into program architecture and design.
2013-10-21T09:17:46 < PaulFertser> It's appealing to novices because it has a flat learning curve.
2013-10-21T09:18:30 < shiftplusone> I've recently been looking into python+flask and that seems pretty good. I haven't taken python seriously before.
2013-10-21T09:19:35 < PaulFertser> ASP.NET seems to be an established platform with support for sane languages (C# and F#) and many ready-made facilities for building "web applications". Whether that's good or bad is up to somebody else to decide.
2013-10-21T09:22:30 < PaulFertser> R2COM: no first-hand experience here (you know how I'm uninterested in using any proprietary technology) but as far as I have understand from reading/hearing about it, yes, the .NET platform is integrated enough so the knowledge from the desktop apps area can be useful in web-programming too. I hope the others will correct me if I'm wrong here.
2013-10-21T09:25:12 < shiftplusone> Meh, I find administrating my own server better than having to send in support tickets and waiting every time something goes wrong.
2013-10-21T09:25:49 < shiftplusone> fair enough
2013-10-21T09:25:57 < shiftplusone> than maybe ASP.NET isn't a bad choice
2013-10-21T09:27:12 < shiftplusone> just give it a go... worst case scenario is you're out $5.
2013-10-21T09:27:26 < shiftplusone> ah
2013-10-21T09:27:56 < shiftplusone> If their customer service doesn't suck, they should be able to let you cancel early and give a refund.
2013-10-21T09:32:39 < dongs> python sucks.
2013-10-21T09:33:30 < shiftplusone> R2COM, you may notice a pattern here. For every language, there will be people going on about how much it sucks. So just pick one and go with it, they're all fit for purpose.

2013-10-21T10:57:52 < dongs> NooM: http://i.imgur.com/8Og4c.jpg
2013-10-21T10:57:58 < dongs> what happens when y ou enter the channel
2013-10-21T10:58:25 < NooM> idk, tell me
2013-10-21T10:58:31 < dongs> i mean thats what happens.
2013-10-21T10:58:44 < NooM> ok
2013-10-21T11:07:18 < NooM> dongs maybe you have a guess, how can it be.. when i allocate mem with uint8_t tmp[1000]; my program stops working, but with new i can allocate more, at least 40kb i have tested
2013-10-21T11:07:42 < NooM> nothing else changed, just the array and crash, hmm
2013-10-21T11:08:02 < dongs> yeah, its called stack
2013-10-21T11:08:18 < dongs> your default stack in startup file is probably NOT set to >1k
2013-10-21T11:08:26 < NooM> ok thx
2013-10-21T11:08:42 < NooM> <3 :D
2013-10-21T11:09:08 < NooM> its 0x00000200
2013-10-21T11:10:03 < dongs> sounds like default stack in st startup files.
2013-10-21T11:10:26 < NooM> what should i consider when i change that ?
2013-10-21T11:10:50 < PaulFertser> NooM: probably you should consider not allocating unusually huge amounts on stack
2013-10-21T11:11:04 < dongs> ^
2013-10-21T11:11:12 < NooM> i dont even have a idea what a stack is :(
2013-10-21T11:11:15 < dongs> i doubt you need array of [1000] things, or even 40k
2013-10-21T11:11:36 < NooM> the 40k i use for display backbuffer
2013-10-21T11:11:47 < NooM> but thats allocated with new, thats fine
2013-10-21T11:11:54 < dongs> ...
2013-10-21T11:12:01 < NooM> :(
2013-10-21T11:12:05 < dongs> why the fuck are you allocating it inside the function
2013-10-21T11:12:22 < dongs> uint8_t crap[40k]; outside any functions.
2013-10-21T11:12:29 < NooM> well its an array in the class and the class gets alocated
2013-10-21T11:12:34 < dongs> haha class
2013-10-21T11:12:40 < dongs> NooM, I have put you on a permanent ignore, public and private. I have found you disturbing, rude and generally not worth talking to.

2013-10-21T11:17:00 < NooM> great changeing the stack size really solved this

2013-10-21T11:37:25 < jpa-> NooM: usually you shouldn't allocate huge stuff on stack.. instead make it static or allocate with new/malloc

2013-10-21T11:38:34 < NooM> gonna read more about that later

2013-10-21T15:54:37 < dongs> does it?
2013-10-21T15:54:43 < dongs> is that 405 vs 507?
2013-10-21T15:54:45 < dongs> er 407
2013-10-21T15:54:58 < Robint91> 417 vs 407
2013-10-21T15:55:03 < dongs> it is

2013-10-21T17:17:14 < Robint91> do I have from the documentation

2013-10-21T17:17:29 < dongs> k 53 is correct
2013-10-21T17:17:34 < dongs> it is in usart handler
2013-10-21T17:17:52 < dongs> but i have no idea what the interrupt CAUSE is.
2013-10-21T17:17:53 < jpa-> how do you figure that you haven't enabled the interrupt?
2013-10-21T17:18:01 < dongs> because i havent
2013-10-21T17:18:08 < jpa-> is it disabled in nvic?
2013-10-21T17:18:18 < Robint91> dongs, USART1?
2013-10-21T17:18:28 < dongs> its in nvic
2013-10-21T17:18:34 < dongs> then i have enabled USART_ITConfig for IT_FE only
2013-10-21T17:18:46 < dongs> but when it fires
2013-10-21T17:19:00 < rewolff> @dongs. I just joined, I just read up on some "history". You seem to have problems with interrupts not firing after a while?
2013-10-21T17:19:12 < dongs> USART_GetITStatus(USART1, USART_IT_FE)
2013-10-21T17:19:16 < dongs> doesnt work
2013-10-21T17:19:27 < Robint91> dongs, what is the state of the pin?
2013-10-21T17:19:44 < Robint91> also is RCC enabled for the USART and such
2013-10-21T17:19:58 < dongs> yeah
2013-10-21T17:20:03 < Robint91> AFIO?
2013-10-21T17:20:04 < dongs> its receive
2013-10-21T17:20:04 < dongs> ing
2013-10-21T17:20:09 < dongs> correct setup
2013-10-21T17:20:20 < rewolff> What I remember is that I had a similar issue.
2013-10-21T17:20:26 < dongs> on F3?
2013-10-21T17:20:43 < rewolff> It seems that once an error flag gets set, the interrupts stop happening.
2013-10-21T17:20:55 < dongs> but i clear it
2013-10-21T17:20:59 < dongs> _FE shit
2013-10-21T17:21:02 < dongs> hm
2013-10-21T17:21:23 < rewolff> So, although I can't find the code in /my/ code anymore, double check that IF you see an error flag in your intererupt routine you make sure that you clear it.
2013-10-21T17:21:34 < rewolff> Do it in every interrupt.
2013-10-21T17:21:50 < rewolff> I'm mostly on "F4" nowadays. 407.
2013-10-21T17:22:01 < dongs> i think i went as far as doing USART1->ICR = 0xffffffff; to fucking just clear everything
2013-10-21T17:22:07 < rewolff> But the usart module probably matches quite a lot with the F3.
2013-10-21T17:22:45 < rewolff> I'd take a bit more care not to clear things that need no clearing, but if you checked that, that should work. :-)
2013-10-21T17:23:21 < rewolff> (it seems I'm on usart2)

2013-10-21T21:32:50 < bsdfox> looking at this http://dangerousprototypes.com/2012/10/28/app-note-using-uart-to-implement-a-1-wire-bus-master/ the first comment seems to indicate "The STM STM32 family can internally connect RX with TX, and TX can be switch to open-drain instead of push-pull"  -- is this correct? I'm looking at the datasheet for stm32f051 and can't figure out what register would allow that
2013-10-21T21:32:57 < Laurenceb_> whats the correct procedure (from host side) for shutting down a usb port?
2013-10-21T21:32:58 < gxti> probably under 300C.
2013-10-21T21:33:46 < gxti> bsdfox: open-drain is basic gpio stuff
2013-10-21T21:34:10 < gxti> you just configure it as alternate function open-drain, just like i2c
2013-10-21T21:34:26 < gxti> i don't know about the internal connection though.
2013-10-21T21:34:56 < bsdfox> gxti, ok I didn't know the OTYPER register was still used in alternate function mode
2013-10-21T21:35:55 < gxti> i don't know about f0 specifically, check the reference manual
2013-10-21T21:36:28 < bsdfox> I don't see anything in there specifically mentioning it.. I was probably making a poor assumption
2013-10-21T21:37:59 < Laurenceb_> one of my datalogge rusers has an issue with sleep mode on a laptop
2013-10-21T21:38:06 < Laurenceb_> running win7...
2013-10-21T21:38:28 < Laurenceb_> seems like its turning off the V_bus
2013-10-21T21:38:58 < Laurenceb_> but voltage drops so slowly that my vbus filter is catching it
2013-10-21T21:38:58 < bsdfox> Laurenceb_, some laptops do. normally there is at least 1 port that stays powered though
2013-10-21T21:39:12 < Laurenceb_> or leakage from the device is pulling up the rail..

2013-10-21T21:39:28 < Laurenceb_> bsdfox: i can't replicate the issue
2013-10-21T21:40:52 < Laurenceb_> so its partly some electrical issue
2013-10-21T21:41:00 < Laurenceb_> but whats the correct proceedure?
2013-10-21T21:41:19 < Laurenceb_> device to standby first? detached first?

2013-10-21T23:34:19 < Laurenceb_> should a usb device be set to the unconnected state before the host removes the power?
2013-10-21T23:35:08 < fbs> no idea
2013-10-21T23:47:59 < zyp> why=
2013-10-21T23:48:06 < zyp> what unconnected state?
2013-10-21T23:50:37 < Laurenceb_> http://www.usbmadesimple.co.uk/ums_3.htm
2013-10-21T23:50:57 < Laurenceb_> Disconnect 	 SE0 for >= 2us
2013-10-21T23:54:28 < Laurenceb_> so im wondering if that state should be forced by the host before the host turns off the power to the device?
2013-10-21T23:56:34 < zyp> that's something that's detected by the host, not done by the host
2013-10-21T23:57:24 < zyp> Idle has D+ high and D- low because of the pullup on D+
2013-10-21T23:57:32 < Laurenceb_> oh
2013-10-21T23:57:36 < Laurenceb_> i see
2013-10-21T23:57:42 < zyp> when the device is unplugged, the pullup disappears and both lines go low, i.e. SE0
2013-10-21T23:57:52 < zyp> and after 2us the host detects that as a disconnect
2013-10-21T23:58:06 < Laurenceb_> so when the host wants to turn off the power
2013-10-21T23:58:12 < Laurenceb_> it can just do it at any time?
2013-10-21T23:58:22 < gxti> sure.
2013-10-21T23:58:29 < gxti> that's not the same thing as standby, though.
2013-10-21T23:58:30 < Laurenceb_> thats annoying
2013-10-21T23:58:32 < zyp> of course, what do you think happens when you just yank out a device?
2013-10-21T23:58:32 < Laurenceb_> i know
2013-10-21T23:58:41 < Laurenceb_> i guess
2013-10-21T23:58:59 < Laurenceb_> but power is designed to detatch last
2013-10-21T23:59:06 < zyp> you want something like safe removal?
2013-10-21T23:59:22 < Laurenceb_> im trying to detect host power down
2013-10-21T23:59:29 < zyp> no, power is designed to attach first
2013-10-21T23:59:37 < Laurenceb_> but v_bus filtering means it is not detected
2013-10-21T23:59:39 < Laurenceb_> right
2013-10-21T23:59:44 < zyp> for what purpose?
--- Day changed Tue Oct 22 2013
2013-10-22T00:00:00 < Laurenceb_> to put the device to sleep
2013-10-22T00:00:02 < zyp> are you a self-powered device?
2013-10-22T00:00:07 < Laurenceb_> or it will flatten the battery
2013-10-22T00:00:08 < Laurenceb_> yes
2013-10-22T00:00:32 < zyp> and you can't detect vbus level properly?
2013-10-22T00:00:38 < Laurenceb_> on some laptops it seems the host removes the power and it drops very slowly over ~10s
2013-10-22T00:00:48 < Laurenceb_> ive got an RC filter that removes it
2013-10-22T00:01:03 < zyp> huh?
2013-10-22T00:01:07 < Laurenceb_> as previously it was vulnerable to interference

2013-10-22T00:01:37 < zyp> it probably just drops slowly because of huge caps on the host side :p
2013-10-22T00:01:43 < Laurenceb_> yes
2013-10-22T00:01:55 < Laurenceb_> i guess ill have to poll it via the lipo charge controller ic
2013-10-22T00:02:00 < Laurenceb_> as that is also connected

2013-10-22T00:02:41 < Laurenceb_> standby with wake on Port A 0 i think
2013-10-22T00:03:15 < zyp> a suspend is a lack of bus activity on the bus, that will be detected by the device, you could also use that to go to sleep, provided that you're also able to wake up again on resume
2013-10-22T00:03:33 < Laurenceb_> hmm
2013-10-22T00:03:45 < Laurenceb_> for some reason thats not the same as the suspend in the ST code
2013-10-22T00:04:02 < zyp> it is
2013-10-22T00:04:07 < Laurenceb_> void Suspend(void) in usb_pwr.c
2013-10-22T00:04:15 < zyp> wat
2013-10-22T00:04:20 < zyp> that's not right
2013-10-22T00:04:24 < Laurenceb_> ok
2013-10-22T00:04:33 < zyp> by the way, I'm assuming you're on F1?
2013-10-22T00:04:37 < Laurenceb_> maybe im getting confused by linux usb /dev stuff
2013-10-22T00:04:40 < Laurenceb_> yes
2013-10-22T00:05:13 < zyp> I'm talking about the SUSP bit in USB_ISTR
2013-10-22T00:05:19 < zyp> (and corresponding WKUP bit)
2013-10-22T00:05:21 < Laurenceb_> ok i was probably being a n00b with forcing usb states on linux
2013-10-22T00:05:24 < Laurenceb_> right
2013-10-22T00:06:05 < zyp> hmm
2013-10-22T00:06:20 < zyp> there is a chapter on suspend/resume under programming considerations for the USB peripheral
2013-10-22T00:06:23 < zyp> I suggest you read that
2013-10-22T00:06:45 < Laurenceb_> ok so in "Suspend" i will add some code to check the vbus voltage
2013-10-22T00:06:46 < Laurenceb_> ok
2013-10-22T00:07:19 < fbs> http://pastie.org/private/fy2hw1fndygtpeqd3m3a incase someone is looking for some max31855 code
2013-10-22T00:08:38 < Laurenceb_> whats that?
2013-10-22T00:08:47 < fbs> a thermocouple readout ic
2013-10-22T00:09:42 < fbs> http://i.imgur.com/GAdcgvzh.jpg?1 its quite easy to use
2013-10-22T00:09:52 < Laurenceb_> oh nice
2013-10-22T00:13:09 < fbs> bomcost is a bit high tho, 8euro and an extra 5 for the connector
2013-10-22T00:15:08 < fbs> now i got to figure out how to do the same with a good adc, that should make scaling to more chans cheaper. analog has some nice appnotes
2013-10-22T00:15:25 < Laurenceb_> why not use opamp + stm32 adc?
2013-10-22T00:23:04 < fbs> stm32 adc might be an option
2013-10-22T00:23:16 < fbs> opamp/lna is always needed
2013-10-22T00:23:30 < zyp> f3 builtin opamp usable? :p
2013-10-22T00:24:03 < fbs> probably not :p
2013-10-22T00:24:19 < fbs> anyway, got to research first

2013-10-22T03:26:33 < dongs> huh
2013-10-22T03:26:37 < dongs> get out, why would that need 6L
2013-10-22T03:26:50 < ds2> Oh
2013-10-22T03:27:02 < ds2> not breaking out much more the memory

2013-10-22T03:27:12 < ds2> the rest is simple stuff (SPI/I2C)
2013-10-22T03:27:14 < dongs> you could probly steal all the routing from there
2013-10-22T03:27:16 < ds2> yes I did
2013-10-22T03:27:21 < dongs> what did tehy do?
2013-10-22T03:27:22 < ds2> but they break out a lot more signals then I need
2013-10-22T03:27:25 < dongs> sure
2013-10-22T03:27:32 < dongs> but thgat shouldnt affect memory r outing
2013-10-22T03:27:34 < ds2> like the LCD. no LCD for me
2013-10-22T03:27:45 < ds2> yes but it would potentially effect the layer count
2013-10-22T03:27:59 < dongs> also why lpddr, why not just use good ol regular cheap ddr2
2013-10-22T03:28:11 < dongs> its not like you need low power or performance here?? I mean its atmel we're talkin about
2013-10-22T03:28:33 < ds2> pin count
2013-10-22T03:28:39 < ds2> DDR2 has more signals and more power rails

2013-10-22T03:35:41 < dongs> the PoP style shits are 0.5mm
2013-10-22T03:36:01 < ds2> the PoP style are nice
2013-10-22T03:36:03 < ds2> no layout :D
2013-10-22T03:36:08 < dongs> some are 0.4mm
2013-10-22T03:36:29 < dongs> i dont see any 0.8mm
2013-10-22T03:36:41 < dongs> 134-ball bga is the only one wiht 0.65mm pitch
2013-10-22T03:40:02 < ds2> hmmm
2013-10-22T03:40:12 < dongs> i duno man, i dont see any "less" signals
2013-10-22T03:40:18 < dongs> how do you figure its less?
2013-10-22T03:40:28 < dongs> still same DQ0..31,, Axxx
2013-10-22T03:40:30 < ds2> there are power rails that aren't there
2013-10-22T03:40:52 < dongs> which?
2013-10-22T03:41:19 < ds2> something ref
2013-10-22T03:41:38 < ds2> oh right no termination
2013-10-22T03:41:41 < ds2> that would affect layout
2013-10-22T03:42:01 < dongs> ref on this board is routed on bottorm
2013-10-22T03:42:01 < ds2> that info is lost in one of these 30 pdfs I have opened :(
2013-10-22T03:42:02 < dongs> and its not hard
2013-10-22T03:42:04 < dongs> its just a couple pins
2013-10-22T03:42:07 < dongs> it doesnt bother anythign
2013-10-22T03:42:22 < dongs> then VCC is just layer3 as you asaw pic
2013-10-22T03:42:52 < ds2> I could go either way on it
2013-10-22T03:43:17 < ds2> if you don't think that process is 4L routeable... then I need to look at cost of 6L boards
2013-10-22T03:44:17 < dongs> well, like i said this A10 board with ddr2 is working just fine on 4L
2013-10-22T03:44:23 < ds2> there is always LPDDR if I can buy them
2013-10-22T03:44:26 < ds2> no... the processor
2013-10-22T03:44:30 < dongs> oh
2013-10-22T03:44:39 < dongs> of course processor is routeable?
2013-10-22T03:44:47 < ds2> 1.8V would save me a regulator
2013-10-22T03:44:48 < dongs> didnt you say you dont need most of hte pins?
2013-10-22T03:44:54 < ds2> yes
2013-10-22T03:45:00 < ds2> but you said it might be hard
2013-10-22T03:45:18 < ds2> I might ask the Atmel guys and see what they ahve to say ;)
2013-10-22T03:45:30 < dongs> good plan
2013-10-22T03:45:49 < dongs> still early, my chinese routing hackers arent online
2013-10-22T03:45:57 < dongs> I can ask them if they ever had aworking lpddr layout in 4layers
2013-10-22T03:46:21 < ds2> all you might get back is loud laughing ;)
2013-10-22T03:46:31 < ds2> armtechcon is in 2 week here
2013-10-22T03:46:51 < dongs> youre doing weird shit on a insane schedule again
2013-10-22T03:47:00 < ds2> always
2013-10-22T03:47:01 < dongs> "i need this 6l board routed by tomrorow"
2013-10-22T03:47:14 < ds2> but I'll be personally routing it
2013-10-22T03:47:18 < dongs> ... in geda
2013-10-22T03:47:22 < ds2> it is the fab part that will be scaring me
2013-10-22T03:47:23 < ds2> no
2013-10-22T03:47:31 < ds2> Eagle!
2013-10-22T03:50:17 < dongs> if cost is not an issue, my place can do 6L board in 24 hours... :) but it isnt gonna be free.
2013-10-22T03:50:25 < ds2> hahahahah
2013-10-22T03:50:31 < ds2> so can the place down the street from here
2013-10-22T03:50:35 < dongs> ya
2013-10-22T03:50:52 < dongs> probly around 500-600bux for prototype w/quick turn
2013-10-22T03:51:02 < dongs> better hope you dont fuck it up
2013-10-22T03:52:44 < emeb> sounds like... "fun"
2013-10-22T03:52:54 < dongs> in eagle, it is
2013-10-22T04:00:25 < ds2> 500-600? hmmm more incentive to try to make 4L work
2013-10-22T04:00:31 < ds2> I have done 4L just fine in eagle
2013-10-22T04:01:05 < ds2> with the way things are going, I might not need quick turn esp if the fab is in asia
2013-10-22T04:01:44 < talsit> does this ring a bell to anyone: "WARNING: Failed to reset CPU. VECTRESET has confused core."
2013-10-22T04:01:48 < talsit> stm32f405RG

2013-10-22T04:05:02 < dongs> ds2: just dont use lpddr2, i dont see any issue with just using DDR>
2013-10-22T04:05:44 < ds2> DDR or you mean DDR2?
2013-10-22T04:05:49 < dongs> yea
2013-10-22T04:05:49 < ds2> DDR is not supported
2013-10-22T04:05:52 < dongs> ddr2
2013-10-22T04:05:53 < ds2> ah
2013-10-22T04:06:04 < ds2> I might do just that

2013-10-22T15:05:49 < capacitor> that'll multiply their rage
2013-10-22T15:05:54 < Steffan-> Why you are even arguing with someone about someone you call " jeri ellsworthless" ?
2013-10-22T15:06:24 < dongs> Steffan-: well, because as usual in forums/etc 13 years old nerds have a hardon for female creatures
2013-10-22T15:06:49 < Steffan-> If it's just to bring someone down you are just as worthless imho.
2013-10-22T15:08:44 < dongs> still
2013-10-22T15:08:53 < dongs> waht do you mean by "bring down' anyway?
2013-10-22T15:08:53 < capacitor> lol
2013-10-22T15:08:59 < capacitor> youtube though, just look at it.
2013-10-22T15:09:01 < dongs> i'm just stating facts
2013-10-22T15:09:09 < dongs> look at wat
2013-10-22T15:09:20 < capacitor> the muttering sputtering pots
2013-10-22T15:09:46 < capacitor> i saw one of jeri's vids, were pages of all these losers asking for her to marry them
2013-10-22T15:09:59 < dongs> lol.
2013-10-22T15:10:00 < dongs> rigfht.
2013-10-22T15:10:04 < capacitor> yep
2013-10-22T15:10:27 < dongs> im having hard time finding a single invention/patent/some  scientific/etc work published that involved her.
2013-10-22T15:10:41 < dongs> yet the blogsphere dubbed her "inventor" as of few weeks ago
2013-10-22T15:10:56 < capacitor> ah welcome to sensationalist bullshit
2013-10-22T15:10:56 < dongs> Your search - jeri ellsworth - did not match any patent results.
2013-10-22T15:11:01 < dongs> i wonder if thas evne her real name
2013-10-22T15:11:41 < capacitor> i strapped a lawnmower to my garden hose, i'm an inventor
2013-10-22T15:11:44 < Robint91> dongs, I think she ain't has a bachelors degree
2013-10-22T15:11:58 < dongs> wouldnt be surprised
2013-10-22T15:13:08 < dongs> Jeri Ellsworth (born 1974) is an American entrepreneur and self-taught computer chip designer.
2013-10-22T15:13:12 < dongs> citation fucking nEEDED.
2013-10-22T15:13:20 < Steffan-> Like a bachelor degree isn't use useless piece of paper capacitor
2013-10-22T15:13:22 < dongs> if I wasnt banned from kikepedia I'd be so editing t his

2013-10-22T15:14:02 < capacitor> there are far worse out there to pick on
2013-10-22T15:14:09 < Robint91> Steffan-, no, it is about the mentuality
2013-10-22T15:14:33 < Steffan-> mentuality ? As in mentality?

2013-10-22T15:16:57 < capacitor> degree goes in the bin

2013-10-22T15:17:04 < dongs> i'm genuinely curious
2013-10-22T15:17:12 < capacitor> dongs she made a laser cannon idk
2013-10-22T15:17:19 < capacitor> nobody here cares or knows
2013-10-22T15:18:06 < capacitor> if you can get past 5 million desperate lonely 40 year old men propositioning her you may be able to ask her
2013-10-22T15:18:21 < Robint91> Steffan-, vs "I know lot's of stuff, but I go the uni to get my degree because A) I want to learn more B) I want to reflect what I know against the teachers/profressors"
2013-10-22T15:19:24 < Robint91> Steffan-, like amateurisme <-> professionalisme
2013-10-22T15:19:46 < dongs> anyway my post is at the top of page so there's plenty of space for trolling

2013-10-22T15:20:27 < Steffan-> You know that because you work(ed) with her.
2013-10-22T15:20:27 < dongs> Robint91: its just trolling, really
2013-10-22T15:20:54 < dongs> Its one thing to critique a project for its failures / merits. It's another thing for your first post on a forum to call someone an "attention whore"
2013-10-22T15:21:11 < dongs> what if hte name is fitting??

2013-10-22T15:26:33 < Steffan-> dongs is a pro. He doesn't tell much about himself so they can't troll him with it.

2013-10-22T15:59:04 < Robint91> I have something strange
2013-10-22T15:59:14 < Robint91> two devices A and B
2013-10-22T15:59:25 < Robint91> both are exaclty the same
2013-10-22T15:59:37 < Robint91> and also produced at the same time

2013-10-22T16:00:02 < Robint91> firmware 2 fails on B
2013-10-22T16:00:15 < Robint91> the only thing changed with 1 to 2
2013-10-22T16:00:24 < Robint91> is the use of an extra pin
2013-10-22T16:00:39 < GargantuaSauce> define "fails"
2013-10-22T16:00:45 < Robint91> but my signal arrives at the pin of the stm32

2013-10-22T16:01:53 < GargantuaSauce> it's not inconceivable that the input on one pin could be destroyed by current or esd or heat or whatever
2013-10-22T16:02:17 < Laurenceb> <GargantuaSauce> that happens on avr
2013-10-22T16:02:23 < GargantuaSauce> rule out a short first though

2013-10-22T16:07:35 < Robint91> but I will check
2013-10-22T16:08:11 < GargantuaSauce> yeah if you have the same issue on multiple boards it's more likely to be a pcb or assembly issue i guess
2013-10-22T16:09:04 < GargantuaSauce> have you done a test case just sampling the gpio input?
2013-10-22T16:09:04 < Robint91> GargantuaSauce, yeah but If I probe on the pin of the TQFP package of the STM32 I measure my correct waveform

2013-10-22T17:15:14 < englishman> wikpedia references some C64 emulator from 2004, which is probable source of money
2013-10-22T17:15:23 < PaulFertser> dongs: do you have something to say about Joanna Rutkowska too? ;)
2013-10-22T17:16:17 < GargantuaSauce> she actually made something complete and useful
2013-10-22T17:16:28 < englishman> GargantuaSauce: but what?
2013-10-22T17:16:42 < GargantuaSauce> bluepill?
2013-10-22T17:17:16 < englishman> what's that?

2013-10-22T17:18:19 < GargantuaSauce> context, bro
2013-10-22T17:18:54 < dongs> She dropped out due to a "cultural mismatch"; Ellsworth said that questioning professors' answers was frowned upon
2013-10-22T17:20:02 < Steffan->  Time to join #worthless dongs
2013-10-22T17:20:32 < englishman> reason dongs dropped out http://i.imgur.com/QRNxwpK.jpg
2013-10-22T17:20:54 < Steffan-> ^^ dongs
2013-10-22T17:21:35 < dongs> Ellsworth has published numerous technical articles online regarding subjects as diverse as homemade semiconductors (2009), homemade electroluminescent (EL) displays (2010), EL phosphor manufacture from common ingredients and ways to make transparent EL backplanes without using expensive indium-tin-oxide coated glass
2013-10-22T17:21:40 < dongs> but wait,
2013-10-22T17:21:47 < dongs> homemade semiconductors was a rip from an old scientific american mag
2013-10-22T17:21:53 < dongs> how could she "publish" it
2013-10-22T17:21:58 < dongs> if it was already published like 20 years ago

2013-10-22T17:50:44 < Laurenceb> theres a reason there are no pico projector modules that are that small

2013-10-22T17:51:19 < Laurenceb> maybe if they teamed up with ST and used the mems laser kit

2013-10-22T18:15:05 < dongs> I do wish there were links to things like schematics and Gerber files, but that’s a lot more work to do. And quite unreasonable if it’s a clever hack of surplus gear. In all fairness, she’s just tossing a pebble in a particular direction and leaving the viewer to take it from there.
2013-10-22T18:15:10 < dongs> haha

2013-10-22T18:16:44 < dongs> I think she likes to “fluff” herself up. I mean, why would you want to build a transistor when you can buy one. ANyone can research how to do it, then impress everyone with the fact that you did it. She portrays herself as an mit engineer, but there is no way to self teath yourself this stuff to the level she proclaims to be at.

2013-10-22T18:24:37 < dongs> when she doesnt actualyl have anything to show about it
2013-10-22T18:25:05 < dongs> inventor = doesn't this usually leave either patents or some kinda trail that somethign gets INVENTEND?
2013-10-22T18:25:10 < dongs> what has actually been invented by jeri
2013-10-22T18:25:25 < englishman> blogs

2013-10-22T18:26:08 < dongs> and a bunch of dudes had to get hired to basicalyl rewrite almost all of it
2013-10-22T18:26:14 < dongs> and deadlines were missed etc.

2013-10-22T18:36:51 < pixelou> But it doesn't work
2013-10-22T18:36:53 < pixelou> ;-)
2013-10-22T18:37:04 < dongs> In an article at http://www.gulli.com/news/retrocomputing-trouble-um-den-2006-08-16/ Jens Schönfeld claims, he has sponsored Jeri Ellsworth for some work on his his C-One, Jeri Ellsword used some of the results on the C64 DTV without giving the results needed for the C-One back to Jens.
2013-10-22T18:37:10 < dongs> Jens said: "Ich habe die Entwicklung des C64-DTV bezahlt!" ( tr.: "I have payed the development of the C64-DTV" )

2013-10-22T18:39:11 < jpa-> pixelou: you could just write the value you want to the USART registers, no need to play around with &= and |=
2013-10-22T18:41:56 < fbs> pixelou: http://pastie.org/8421628 is what im using on the f0 atm
2013-10-22T18:41:56 < pixelou> the only defined variables I use are the ones from stm32f4xx.h
2013-10-22T18:41:56 < fbs> does it compile?
2013-10-22T18:41:56 < pixelou> yes it does
2013-10-22T18:41:56 < pixelou> and the interruption when TXE flag is set happens
2013-10-22T18:41:56 < fbs> so what doesnt work?
2013-10-22T18:41:56 < pixelou> well there is nothing on the tx pin
2013-10-22T18:41:56 < fbs> whats up with the way you write to CR1?
2013-10-22T18:41:56 < fbs> uart->CR1 |= CR1
2013-10-22T18:41:57 < pixelou> It is stupid code
2013-10-22T18:41:57 < pixelou> ;-)
2013-10-22T18:42:28 < pixelou> I think I have removed some useless lines of code and forgot to clen things up
2013-10-22T18:42:37 < fbs> why not use the stdlib?
2013-10-22T18:42:43 < pixelou> btw using a variable let me print the value in gdb
2013-10-22T18:43:38 < pixelou> It is for learning purpose
2013-10-22T18:44:45 < fbs> doesnt help debugging it
2013-10-22T18:45:00 < fbs> the lib is a bit ugly but seems to work
2013-10-22T18:45:16 < pixelou> indeed
2013-10-22T18:46:09 < jpa-> register writing works just as well
2013-10-22T18:46:43 < dongs> pixelou: why dont you just use stdperiphlib?
2013-10-22T18:46:53 < jpa-> because stdperiph is stupid :P
2013-10-22T18:47:01 < fbs> jpa-: ofc but  uint16_t CR2 = (0x1 << 7) + (0x1 << 4) + (0x1 << 15); is a lot harder to figure out
2013-10-22T18:47:03 < dongs> i mean, if youre just starting out and you want shit to WORK, why would you spend hours writing into individual registers and breaking shit? :)
2013-10-22T18:47:11 < pixelou> I suspect it has something to do with the gpio part
2013-10-22T18:47:15 < jpa-> fbs: yes, but it's written in stupid way
2013-10-22T18:47:46 < fbs> pixelou: if you copy my gpio setup it should work
2013-10-22T18:47:51 < fbs> just got to fix the defines

2013-10-22T20:16:05 < dongs> where is your actual rtc interrupt handler ?
2013-10-22T20:17:13 < zyp> also, which chip is this?

2013-10-22T20:19:28 < zyp> so anyway, I can't see anything resembling setting the interrupt enable flag in some rtc config register, which I assume you have to do in addition to enabling it in the nvic
2013-10-22T20:19:57 < zyp> and I'm too lazy to look it up in the RM today

2013-10-22T21:11:51 < fbs>  - To enable the RTC Alarm interrupt, the following sequence is required:
2013-10-22T21:11:53 < fbs>    - Configure and enable the EXTI Line 17 in interrupt mode and select the rising

2013-10-22T23:16:00 < GargantuaSauce> and shit doesn't run
2013-10-22T23:16:04 < GargantuaSauce> wat do
2013-10-22T23:16:51 < emeb> neat trick!
2013-10-22T23:18:30 < jpa-> GargantuaSauce: if using texane stlink, hold the reset button until the first lines roll on the screen
2013-10-22T23:18:43 < Laurenceb_> rick roller
2013-10-22T23:19:02 < jpa-> it's surprisingly simple to time the reset button, much easier than finding the openocd command to do it ;)
2013-10-22T23:20:53 < GargantuaSauce> i guess a power cycle fixed it actually....still says f2 but my sauce is running again and it may or may not have said f2 all along i dunno!

2013-10-23T04:33:13 < GargantuaSauce> anyone got an explanation for http://xn--d-bga.su/spigaps.png ? cant figure out why there's gaps between the bytes. http://bcas.tv/paste/results/L1vA1K27.html
2013-10-23T04:45:46 < emeb> wasn't there a big discussion of this a few days ago.
2013-10-23T04:45:46 < GargantuaSauce> i suspect it's because the irq triggering and the peripheral register read/writes are taking more than 16 APB clock cycles
2013-10-23T04:46:13 < GargantuaSauce> but this confuses me because that means that the fastest clock mode (/2) is basically pointless
2013-10-23T04:46:25 < emeb> you need to ensure you're doing an 8-bit write to the DR or else the SPI peripheral assumes you want 16-bit xfer.
2013-10-23T04:46:34 < GargantuaSauce> it's not a 16 bit transfer
2013-10-23T04:46:40 < GargantuaSauce> yellow is sck
2013-10-23T04:46:50 < emeb> ya
2013-10-23T04:46:56 < GargantuaSauce> eight pulses
2013-10-23T04:47:14 < emeb> fifo?
2013-10-23T04:47:56 < GargantuaSauce> nope, what you see in the snippet is what is running
2013-10-23T04:48:22 < GargantuaSauce> i guess dma would indeed make that mode worthwhile

2013-10-23T04:55:24 < GargantuaSauce> wrestling with my incompetence
2013-10-23T04:55:54 < dongs> why dont you take someone elses published ideas and retweet them on hack-a-day as your own invention
2013-10-23T04:56:07 < dongs> just make sure its far enough back in time that blogsophere wont notice
2013-10-23T04:56:11 < emeb> wondering - is there a way to trigger a software interrupt?
2013-10-23T04:56:21 < GargantuaSauce> it's called a function :V
2013-10-23T04:56:28 < dongs> what software interrupt?
2013-10-23T04:56:28 < GargantuaSauce> dongs because i have no interest in hype
2013-10-23T04:56:32 < dongs> you can just call the IRQ?
2013-10-23T04:56:51 < emeb> no, I want a low-priority background process.
2013-10-23T04:56:52 < dongs> or im sure you can set some bit in some nvic register to force it
2013-10-23T04:56:55 < dongs> systick?
2013-10-23T04:57:07 < emeb> that is kicked off when I flip a bit in another ISR.
2013-10-23T04:57:40 < dongs> you can trigger exti interrupts manually
2013-10-23T04:57:44 < dongs> so, setup a exti one
2013-10-23T04:57:49 < emeb> aha!
2013-10-23T04:57:49 < dongs> w/o hardware attached
2013-10-23T04:58:15 < emeb> that sounds perfect.
2013-10-23T04:59:04 < emeb> working on a stupid app that can't use DMA for the I2S port due to real-time inputs.
2013-10-23T04:59:18 < emeb> need to manually feed data to the I2S DR
2013-10-23T04:59:29 < emeb> and then generate the data in another process.
2013-10-23T04:59:57 < dongs> don't forget to credit inventor dongs in your dickstarter
2013-10-23T05:00:14 < dongs> i wonder what jeri's IP address is
2013-10-23T05:00:17 < emeb> Your name will feature prominently in my comments.
2013-10-23T05:00:35 < dongs> seattle is what speakasy or something for ISP/

2013-10-23T05:07:37 < dongs> sorry to disappoint
2013-10-23T05:08:09 < GargantuaSauce> yeah i suspected you just toss pcbs on the grill for reflow between big macs
2013-10-23T05:08:32 < dongs> yep
2013-10-23T05:08:36 < GargantuaSauce> the flux really adds flavour too
2013-10-23T05:09:36 < gxti> from what i've heard mcdonalds is pretty classy in some countries, catering to local tastes and whatnot. but i guess in japan it's probably just a vending machine with burgers and used panties.
2013-10-23T05:10:24 < GargantuaSauce> i went to one in korea and it tasted exactly the same, every bit as regrettable
2013-10-23T05:10:33 < GargantuaSauce> they had some local twists too, bulgogi burgers and so on
2013-10-23T05:16:18 < GargantuaSauce> how retarded would it be to do dma for really small spi transfers? 33 bytes at the largest down to like...2
2013-10-23T05:17:20 < englishman> i think dma is only there so you can learn how to use dma and when it works say "oh, that's neat"
2013-10-23T05:17:46 < dongs> GargantuaSauce: if its worth setup and/or if you wanna do other shit whlie its happening sure
2013-10-23T05:17:59 < dongs> if youre just gonna while(!DMA->done); then might as well not care?
2013-10-23T05:18:51 < GargantuaSauce> well i am looking at doing solely an interrupt driven one with no dma but it's turning into a huge pain in the ass
2013-10-23T05:19:07 < GargantuaSauce> every implementation i can find in real applications just polls or uses dma transfers
2013-10-23T05:21:40 < GargantuaSauce> what's complicating it is that this particular slave needs the NSS pin low for the duration of a command and its payload, so i cant just combine adjacent commands into a big transfer and use hardware ss
2013-10-23T05:22:10 < dongs> wait a sec
2013-10-23T05:22:14 < dongs> if jeri was female
2013-10-23T05:22:16 < dongs> and she's like 40 now

2013-10-23T06:17:27 < emeb> dongs: EXTI software IRQ works. thx.
2013-10-23T06:17:57 < dongs> ^_^
2013-10-23T06:18:14 < dongs> did ytou have to commit some hardware for it?
2013-10-23T06:18:19 < dongs> or just didnt setup EXTI_Line shit or whatever
2013-10-23T06:22:07 < gxti> you can soft trigger any unused irq
2013-10-23T06:24:52 < dongs> now you tell him
2013-10-23T06:24:53 < dongs> how?
2013-10-23T06:25:05 < dongs> i only knew of exti
2013-10-23T06:25:23 < gxti> nvic
2013-10-23T06:26:16 < gxti> "set pending register"
2013-10-23T06:28:42 < gxti> it's not fundamentally different from exti, or from setting the status flag inside the peripheral, except those require that the peripheral is clocked
2013-10-23T06:36:40 < dongs> trolling
2013-10-23T06:39:27 < dongs> is there peripheral-to-peripheral mode?
2013-10-23T06:39:34 < dongs> i thought it was p2m and m2p
2013-10-23T06:39:54 < emeb> dongs: no hardware necessary. there's a software trigger bit for the EXTI
2013-10-23T06:40:23 < dongs> yea. apparently, for any interrupt as well, according to gxti
2013-10-23T06:40:40 < emeb> huh. dunno how that would work, but this was simple.
2013-10-23T06:40:57 < gxti> probably NVIC_SetPending(Derpy_IRQn);
2013-10-23T06:41:08 < gxti> just guessing.
2013-10-23T06:41:23 < emeb> One thing I'm learning though - not using DMA to spew data into the I2S port is stupid.
2013-10-23T06:41:38 < emeb> you have to hand it every halfword, one at a time.
2013-10-23T06:41:55 < emeb> so for stereo audio out you get interrupted at 2x the sample rate.
2013-10-23T06:42:27 < gxti> what's the most i2s ports on a single stm32 part? like two?
2013-10-23T06:42:39 < emeb> gxti: AFAICT yes
2013-10-23T06:42:43 < gxti> R2COM: wire them together
2013-10-23T06:42:54 < emeb> and I'm using both on this project, so 4 IRQs/sample!
2013-10-23T06:43:23 < gxti> i have some wacky mixer idea, but analog probably makes more sense
2013-10-23T06:43:35 < dongs> whats hte fucking point of just receiving SPI1 and sending SPI2
2013-10-23T06:43:40 < dongs> if youre doing thatm, just fucking connect htem together

2013-10-23T06:44:22 < gxti> nothing too exciting, just a DAC with multiple PCs feeding it
2013-10-23T06:44:44 < emeb> how do the PCs feed data?
2013-10-23T06:45:10 < gxti> usb probably? which means a lot of stm32s, lol.
2013-10-23T06:45:22 < dongs> usb hub that shit
2013-10-23T06:45:41 < emeb> hubs don't do many -> one do they?
2013-10-23T06:46:05 < emeb> ie many hosts -> one device
2013-10-23T06:46:17 < gxti> spdif would be simpler but there's no way to backfeed clock to the pc so digitally mixing would suck
2013-10-23T06:46:28 < gxti> as they'd all be out of sync and need to be retimed too
2013-10-23T06:46:44 < emeb> right - you'd need a resampler on every channel
2013-10-23T06:46:55 < gxti> hence the dumb solution, analog
2013-10-23T06:46:58 < emeb> which is doable, but ugly.
2013-10-23T06:47:35 < emeb> hmm... interesting problem.
2013-10-23T06:48:01 < emeb> so, multiple STM32 USB Audio class devices taking data in on USB and spewing I2S data out.
2013-10-23T06:48:19 < gxti> not all of the sources are important, it's actually two PCs and a beagleboner and for the PCs i'm more concerned about working reliably in games and such than quality, the beagleboner is the only one that needs to do 192khz/24bit
2013-10-23T06:48:26 < emeb> then feed them all to an FPGA with a multi-channel resampler, then to a high-quality audio DAC?

2013-10-23T06:49:08 < dongs> whats odd is its not entire panel thats fucked
2013-10-23T06:49:11 < dongs> just 2/6
2013-10-23T06:49:12 < gxti> shouldn't have left the fab
2013-10-23T06:49:14 < emeb> scrub with solvent?
2013-10-23T06:49:18 < dongs> fucking bizzare
2013-10-23T06:49:24 < dongs> well, too late ill just toss the shit
2013-10-23T06:49:59 < dongs> so weird
2013-10-23T06:50:03 < gxti> emeb: yeah that's one way, but while analog is not my strong point i know it's the "right" way to do it. and for bonus points i won't spend months avoiding writing the hdl.
2013-10-23T06:50:49 < dongs> make your STM32 a USB hub
2013-10-23T06:50:53 < dongs> (in software)
2013-10-23T06:51:00 < dongs> then present a bunch of USB Audio class devices
2013-10-23T06:51:01 < dongs> behind the hub
2013-10-23T06:51:05 < dongs> done
2013-10-23T06:51:28 < gxti> wtf good would that do?
2013-10-23T06:51:35 < dongs> you onyly need one stm32?
2013-10-23T06:51:55 < gxti> i have 3 PCs to connect it to
2013-10-23T06:52:37 < gxti> that's the opposite of what a hub does
2013-10-23T06:52:42 < emeb> gxti: yeah. Just means lots of audio DACs. Not a big deal though.
2013-10-23T06:52:43 < dongs> oh ok
2013-10-23T06:53:08 < dongs> why not use that newfag USB>DAC thing from BRRR-BROWN
2013-10-23T06:53:14 < dongs> the one that recently got liek 500k on dickstarter
2013-10-23T06:53:17 < dongs> wiht 384khz sampling
2013-10-23T06:53:35 < emeb> yeah - those TI/BB USB DACs are pretty easy.
2013-10-23T06:53:43 < emeb> I did a project with one b4
2013-10-23T06:53:56 < dongs> but you didnt dickstart it on 6layer pcb
2013-10-23T06:54:20 < dongs> shoulda used a zync
2013-10-23T06:55:13 < dongs> yea that. in 686BGA
2013-10-23T06:55:13 < emeb> dongs: got a zynq on order. Should have it in Dec.
2013-10-23T06:55:26 < emeb> looking forward to playing with that...
2013-10-23T06:55:33 < dongs> is availability that bad?
2013-10-23T06:55:49 < dongs> or is that the dickstarter thing
2013-10-23T06:55:52 < dongs> DAQ whatever
2013-10-23T06:55:57 < emeb> Nah: http://www.digilentinc.com/Products/Detail.cfm?NavPath=2,400,1198&Prod=ZYBO
2013-10-23T06:56:05 < emeb> just not done building 'em yet.
2013-10-23T06:56:20 < emeb> and totally not KS.
2013-10-23T06:57:19 < emeb> yeah - please rape me for $900

2013-10-23T06:58:14 < emeb> already on order
2013-10-23T06:59:04 < emeb> 1) cheaper than zedboard

2013-10-23T12:39:12  * Laurenceb thought of another reason Castar is useless
2013-10-23T12:39:37 < Laurenceb> they are using off the shelf retroreflector fabric
2013-10-23T12:39:47 < Laurenceb> which scatters diffuse light
2013-10-23T12:40:05 < Laurenceb> so the contrast ratio will be non-existent
2013-10-23T12:46:47 < jpa-> wasn't the point to detect modulated IR light or something? (i haven't studied it closely)
2013-10-23T12:47:44 < Robint91> jpa-, euh
2013-10-23T12:48:13 < Laurenceb> http://www.mpoweruk.com/images/lithium_window.gif <- useful

2013-10-23T12:48:37 < Laurenceb> theres nothing smart like that
2013-10-23T12:49:06 < jpa-> ah
2013-10-23T12:49:29 < jpa-> what does it really do? i didn't quite understand the whole hype
2013-10-23T12:49:46 < jpa-> was it supposed to detect the location of real world stuff, or project something new there? or what
2013-10-23T12:49:59 < Laurenceb> both
2013-10-23T12:50:09 < Laurenceb> but its a clusterfuck
2013-10-23T12:50:25 < jpa-> is there also a visible light projector? i somehow got an impression that it was IR projector
2013-10-23T12:50:26 < Laurenceb> idea seems to be smart but it went downhill from there
2013-10-23T12:50:36 < Laurenceb> its visible
2013-10-23T12:50:44 < Laurenceb> im tempted to do it properly
2013-10-23T12:51:10 < Laurenceb> single visibile projector with a ir camera and 2d barcode printed in ir ink
2013-10-23T12:51:14 < Laurenceb> for location
2013-10-23T12:51:26 < Laurenceb> thatd be ~1/3rd the cost
2013-10-23T13:03:04 < jpa-> Laurenceb: hmm.. if the projector leds could be pulsed at very small duty and the active shutters be closed for most of the time, that would increase contrast against ambient light
2013-10-23T13:03:17 < jpa-> but somehow darkening the room doesn't seem like the biggest problem there

2013-10-23T13:21:25 < rewolff> Laurence, if you SLOWLY recharge (C/20 or thereabouts), and quickly after dropping below 3V, the damage is usually small.
2013-10-23T13:22:01 < Laurenceb> rewolff: yeah
2013-10-23T13:22:13 < Laurenceb> but its supposed to have a protection circuit
2013-10-23T13:22:32 < Laurenceb> im going to have to return it, I need a protection circuit for CE
2013-10-23T13:23:14 < rewolff> Yeah. You're right....
2013-10-23T13:23:50 < rewolff> The problem is that the specs say the protection SHOULD kick in at 2.5V nominal, which is lower than the lowest-allowed 2.75 nominal for the cell.
2013-10-23T13:23:59 < rewolff> So the SPECs already are BAD.
2013-10-23T13:24:24 < rewolff> I'd rather have the protection kick in at 3.0

2013-10-23T13:25:44 < rewolff> Another thing is that you have very, very little capacity below 3.0V. So drawing just a few microamps  to power the protection circuitry can drain a battery well below the cutoff even if the protection works.....
2013-10-23T13:26:21 < rewolff> So if the protection circuitry is not properly designed to cut itself off as well, it might drain the battery during the course of a few days.....
2013-10-23T13:27:03 < dongs> lets say I have a locked stm chip, I go and change option bytes to disable ROP, then I watch power consumption with uA meter and i drop power after xx ns , enough to kill ROP bit but not enough to kill (some/all/most) of flash. feasible? or does ROP get clearaed only after flash is gone

2013-10-23T13:47:54 < jpa-> you are welcome
2013-10-23T13:48:14 < rewolff> @dongs: That sort of "bugs" that fell for those tricks are now "well known". So you'd expect a modern chip to do the "proper" thing. On the other hand, stupid bugs have been known to creep into chips before.

2013-10-23T13:53:29 < Laurenceb> maybe i could try and work out wtf they did to the protection circuit
2013-10-23T13:53:40 < Laurenceb> or buy direct from varta..

2013-10-23T13:54:39 < jpa-> so what do you want to do with it?

2013-10-23T14:48:21 < Laurenceb> discharge protect isnt working on a significant proportion of them
2013-10-23T14:49:37 < zyp> isn't working like it's designed to do or isn't working like you believe it should do?
2013-10-23T14:51:10 < Laurenceb> i dunno
2013-10-23T14:51:12 < jpa-> also, isn't that just "stop it from blowing up" protection, i.e. not supposed to be part of normal use
2013-10-23T14:51:16 < Laurenceb> i can discharge to 1.5v
2013-10-23T14:51:27 < zyp> jpa-, exactly
2013-10-23T14:51:32 < Laurenceb> yeah, but i need it for safety

2013-10-23T14:52:15 < jpa-> CE requires protection circuit for non-user replaceable batteries now?
2013-10-23T14:52:17 < zyp> Laurenceb, but it doesn't blow up, does it?

2013-10-23T14:56:09 < Laurenceb> luckily i have such info

2013-10-23T20:10:06 < Steffanx> http://www.wvshare.com/product/Analog-Test-Board.htm .. lol it supports mp3 output :D :D :D
2013-10-23T20:11:25 < zyp> hmm, you know what's a shame?
2013-10-23T20:11:36 < Steffanx> ..
2013-10-23T20:11:38 < zyp> that the F429 didn't get a built-in HS PHY
2013-10-23T20:12:24 < Steffanx> oh heh.. im still waiting for mine, but i don't think it'll ever arrive.
2013-10-23T20:12:27 < Steffanx> -r
2013-10-23T20:12:53 < zyp> that's probably one of the largest disadvantages with stm32 when compared to nxp and atmel's cortex-m chips :p
2013-10-23T20:13:16 < zyp> the addition of sdram controller probably removed another

2013-10-23T20:23:28 < zyp> unless it's the same
2013-10-23T20:23:44 < zyp> the one in lpc43xx is licenced ARM IP
2013-10-23T20:23:52 < jpa-> yeah, st's datasheets don't seem to have as much information as lpc43xx
2013-10-23T20:24:13 < zyp> did you compare the register layouts?

2013-10-24T02:43:46 < Laurenceb_> wow so cheap
2013-10-24T02:43:52 < BrainDamage> we should ask a psychologist if there's a name for a syndrome to try to prove everyone wrong / outdo them
2013-10-24T02:44:36 < Laurenceb_> haha

2013-10-24T02:54:18 < Steffanx> Won't Blaxter syndrome fit BrainDamage?
2013-10-24T02:54:46 < Steffanx> or perhaps figure out mr d on gs last name and use that.

2013-10-24T08:54:25 < emeb_mac> nifty
2013-10-24T08:54:55 < emeb_mac> aha - was going to ask how you set the PLL

2013-10-24T08:55:25 < emeb_mac> but fixed

2013-10-24T08:56:37 < emeb_mac> yeah - I know how PLLs work. Just wondered if the /6 was programmable. but I assume not.
2013-10-24T08:58:20 < emeb_mac> that's what prototypes are for.
2013-10-24T08:58:51 < dongs> protodongs

2013-10-24T09:05:27 < emeb_mac> why?
2013-10-24T09:05:46 < emeb_mac> I see - little gaps
2013-10-24T09:06:03 < emeb_mac> should have gotten the cheap ebay ones. :P
2013-10-24T09:06:44 < emeb_mac> got access to a TDR? any idea how much that discontinuity hurts?
2013-10-24T09:07:20 < emeb_mac> vector network analyzer might do it too...
2013-10-24T09:07:33 < ds2> Mmmmmm VNA
2013-10-24T09:09:48 < talsit> is there a specific reason to leave the traces without soldermask?
2013-10-24T09:11:15 < talsit> which is also why you pull back the mask
2013-10-24T09:11:25 < talsit> ?

2013-10-24T09:18:09 < emeb_mac> probably diverts the E field towards the surrounding ground plane.
2013-10-24T09:18:43 < emeb_mac> skews the impedance away from ideal stripline calcs.
2013-10-24T09:19:14 < emeb_mac> you could probably compensate by tweaking the width of the trace, but the mask is not well controlled.
2013-10-24T09:20:16 < emeb_mac> that's what I'm saying. keep it simple and just leave the mask off.
2013-10-24T09:21:26 < emeb_mac> is that OSHpark?
2013-10-24T09:21:38 < emeb_mac> 4L?
2013-10-24T09:21:39 < ds2> speaking of striplines... is there a easy way to calculate one buried between layers? lots of calc for layers on top
2013-10-24T09:21:57 < emeb_mac> what's the thickness between top and layer 2?
2013-10-24T09:22:27 < emeb_mac> sufficiently controlled for good RF?
2013-10-24T09:22:45 < emeb_mac> I've talked to some RF guys who didn't like OSHpark's rules.
2013-10-24T09:23:27 < emeb_mac> ya
2013-10-24T09:23:50 < emeb_mac> IIRC there was some deviation from the expected response.
2013-10-24T09:23:59 < emeb_mac> s/expected/desired/
2013-10-24T09:25:20 < emeb_mac> ds2: http://www.analog.com/static/imported-files/tutorials/MT-094.pdf
2013-10-24T09:25:34 < emeb_mac> buried is called symmetrical stripline
2013-10-24T09:25:40 < emeb_mac> on top is called microstrip

2013-10-24T09:27:23 < emeb_mac> not bad
2013-10-24T09:28:52 < emeb_mac> same 30pf cable?
2013-10-24T09:35:21 < emeb_mac> are the Pasternack launchers really worth the high prices?
2013-10-24T09:35:40 < emeb_mac> everything they sell is like 3x-4x the price of other suppliers.
2013-10-24T09:38:31 < ds2> emeb_mac: nice... I wish they had that back when I was in school
2013-10-24T09:39:35 < ds2> I mean simple write ups
2013-10-24T09:40:15 < ds2> the school version was 60pages of text about the theory and 2-3 hours worth of lecture - homework was to derive those equations for maxwell eqns
2013-10-24T09:41:28 < ds2> yes
2013-10-24T09:41:50 < ds2> but that 7 pages made it much more understandable
2013-10-24T09:42:11 < ds2> it took a few pages like that to tell me a FIR filter is just convolution
2013-10-24T09:42:37 < ds2> I guess
2013-10-24T09:42:56 < ds2> E fields and B fields are very nice and all
2013-10-24T09:43:03 < ds2> but how does one use it to do useful stuff :D

2013-10-24T15:13:16 < Tectu> how would one design a CPU usage meter, btw.
2013-10-24T15:13:55 < Tectu> count tasks?
2013-10-24T15:14:57 < GargantuaSauce> in chibi?
2013-10-24T15:15:22 < Tectu> yep
2013-10-24T15:15:44 < Tectu> ah, each thread actually has a used sys ticks counter.   chThdGetTicks(tp)    probably a start?
2013-10-24T15:15:58 < GargantuaSauce> yup that's probably all you really need
2013-10-24T15:16:34 < Tectu> have you already implemented such a thing, GargantuaSauce ?
2013-10-24T15:17:22 < GargantuaSauce> not in an rtos setting no
2013-10-24T15:19:01 < GargantuaSauce> but yeah, should just need to sample a running total of those at fixed intervals
2013-10-24T15:19:13 < GargantuaSauce> won't be perfect but it will probably do
2013-10-24T15:19:19 < Tectu> jup
2013-10-24T15:19:56 < Tectu> well, isn't it just the ratio between used systicks of the idle thread compared to the sum of all used systicks of the other threads?
2013-10-24T15:21:27 < GargantuaSauce> yes, except for stuff like context switches that probably won't be included
2013-10-24T15:25:33 < Tectu> I assume that won't even give 0.5% error - but yes, of course it depends on the actual operation the thread executes

2013-10-24T21:08:14 < Robint91> hi all
2013-10-24T21:15:13 < emeb> quiet channel lately
2013-10-24T21:16:04 < zyp> that's because you aren't talking enough
2013-10-24T21:16:25 < zyp> emeb, by the way, there's one thing that annoys me about the bmp2 layout :p
2013-10-24T21:16:37 < emeb> zyp: what's that?
2013-10-24T21:17:04 < zyp> the stlink-style headers, how they are sticking out
2013-10-24T21:17:20 < zyp> it's a bit annoying when I'm throwing it in my bag or something to bring it along somewhere
2013-10-24T21:17:58 < emeb> what's the alternative? RA connector?
2013-10-24T21:18:04 < emeb> or just leave the stlink off
2013-10-24T21:18:05 < zyp> a saner layout would have 90deg-angle header, positioned with the ends along a board edge
2013-10-24T21:18:44 < zyp> that way they don't protude in a way that they would damage/get damaged by stuf
2013-10-24T21:19:10 < BrainDamage> you could get a small foam padded box
2013-10-24T21:19:17 < BrainDamage> not an awesome solution, but works
2013-10-24T21:19:48 < zyp> I'm currently sitting in an airport with a bmp2 wrapped in bubble-wrap in my backpack :p

2013-10-24T21:20:58 < zyp> brought it along to do some hacking, haven't done shit
2013-10-24T21:20:59 < zyp> :p
2013-10-24T21:21:02 < BrainDamage> does it have curled wires sticking out?
2013-10-24T21:21:10 < zyp> huh?
2013-10-24T21:21:13 < emeb> better to have it and not need it.
2013-10-24T21:21:18 < BrainDamage> and a giant 7-seg display
2013-10-24T21:21:27 < zyp> emeb, true
2013-10-24T21:21:30 < emeb> coiled wires sticking out - just like an explosive timer in the movies.
2013-10-24T21:21:35 < emeb> always coiled.
2013-10-24T21:21:40 < zyp> ah
2013-10-24T21:21:43 < emeb> cut the red one.
2013-10-24T21:21:46 < emeb> always the red one.
2013-10-24T21:21:59 < zyp> they didn't complain in the security check
2013-10-24T21:22:03 < emeb> because every bomb hacker in the world consistently uses the same color coding.
2013-10-24T21:22:28 < emeb> I've been thru security w/ boxes full of random electronics. They never care.
2013-10-24T21:22:32 < BrainDamage> and is sufficiently dumb to make it look like a bomb
2013-10-24T21:22:39 < zyp> yeah
2013-10-24T21:23:06 < zyp> the only time one of the guards paid some attention was when I brought along a bag of RC lipo batteries :p
2013-10-24T21:23:22 < emeb> got my oscillator sync stuff working yesterday.
2013-10-24T21:23:26 < zyp> he seemed to study it thoroughly before letting it pass
2013-10-24T21:24:11 < emeb> using the DMA CNDTR reg works great.
2013-10-24T21:24:19 < zyp> :)
2013-10-24T21:25:38 < emeb> EXT Interrupt triggers read of the reg, then I queue the event in a little bitmap & read later while computing the waveform.

2013-10-24T21:30:53 < emeb> anyone tried OSHstencils.com?
2013-10-24T21:31:05 < emeb> ordered one from them the other day - should have it soon.

2013-10-24T21:34:00 < emeb> wtf good does that do them when they already have coarse wifi loc?
2013-10-24T21:37:31 < emeb> probably going to have to dump this game - every update runs slower and jerkier on my old Sammy.
2013-10-24T21:41:06 < Steffanx> you are not the type to play games anyway
2013-10-24T21:42:21 < emeb> usually not.

2013-10-24T23:14:16 < Laurenceb_> I'm trying to control a pump with a ton of stiction
2013-10-24T23:18:03 < gxti> moar lube
2013-10-24T23:18:11 < Laurenceb_> hmm I'd rather not
2013-10-24T23:18:19 < Laurenceb_> its designed to be lube free
2013-10-24T23:18:22 < emeb> so you goose it until it breaks free, but then it overshoots?
2013-10-24T23:18:27 < Laurenceb_> yes
2013-10-24T23:18:33 < Laurenceb_> giving sawtooth oscillation
2013-10-24T23:18:48 < emeb> violin bow - slip/stick/slip/stick
2013-10-24T23:19:09 < Laurenceb_> yeah
2013-10-24T23:19:36 < Laurenceb_> there must be a standard solution to this
2013-10-24T23:19:49 < emeb> time for a different pump
2013-10-24T23:19:54 < Laurenceb_> nah
2013-10-24T23:20:03 < Laurenceb_> I have £1k of these in stock
2013-10-24T23:20:22 < gxti> is it capable of running smoothly at the correct speed once it's unstuck?
2013-10-24T23:20:22 < Laurenceb_> some batches work ok
2013-10-24T23:20:32 < Laurenceb_> yes
2013-10-24T23:20:46 < Laurenceb_> but it has to stop once the pneumatics is at the correct pressure
2013-10-24T23:21:08 < emeb> add a bleed valve so it never has to stop?
2013-10-24T23:21:28 < Laurenceb_> yeah but that leaks power
2013-10-24T23:21:35 < Laurenceb_> it does work tho
2013-10-24T23:21:38 < Laurenceb_> tried that already
2013-10-24T23:21:59 < gxti> well then wtf do you want
2013-10-24T23:22:10 < gxti> if you can't back off slower there's not much you can do i guess
2013-10-24T23:22:21 < Laurenceb_> dunno lol
2013-10-24T23:22:26 < Laurenceb_> i know
2013-10-24T23:22:35 < Laurenceb_> process the PID controller output
2013-10-24T23:22:35 < gxti> did you buy the pumps?
2013-10-24T23:22:42 < Laurenceb_> into an oscillating signal
2013-10-24T23:22:47 < Laurenceb_> that might help
2013-10-24T23:22:52 < Laurenceb_> well, my employer did :P
2013-10-24T23:23:27 < Laurenceb_> or maybe just add the occasional ~10ms spike to the output to free up the motor
2013-10-24T23:24:30 < NooM> hey someone can help me figure out values for a timer?

2013-10-25T14:31:16 < Steffanx> Yes fuck you zyp. You know it ALL.
2013-10-25T14:31:42 < zyp> whoa
2013-10-25T14:31:54 < zyp> what's up?
2013-10-25T14:32:36 < Steffanx> "nah, I'm just answering your stupid question" i was f*cking serious. I'm not into USB at all, so i really didn't know it was hsic (ip)
2013-10-25T14:35:18 < karlp> doesn't help any of us know what the fuck dongs was on about though.
2013-10-25T14:35:21 < karlp> who's "they" ?
2013-10-25T14:35:51 < zyp> huh
2013-10-25T14:36:05 < zyp> how can't you see it was a typo
2013-10-25T14:36:23 < zyp> «they did ship usb», i.e. those connectors he were talking about earlier
2013-10-25T14:36:43 < zyp> 12:18:14 < dongs> and.. it was supposed to ship today, kikes
2013-10-25T14:36:56 < dongs> contextual chats
2013-10-25T14:36:57 < karlp> could have been, "oooo, they did hsic usb" with me not knowing who they were
2013-10-25T14:37:08 < dongs> they're hard
2013-10-25T14:37:17 < jpa-> fortunately i have enough people in ignore, that if something that dongs says doesn't seem sensible, i can just figure out he was talking with someone who i don't see :P
2013-10-25T14:37:20 < karlp> there's a bunch of chatz after him complaining about shipping :)
2013-10-25T14:37:34 < karlp> you ignore people here jpa- ?
2013-10-25T14:37:39 < dongie> jpa-: in this channel?
2013-10-25T14:37:54 < jpa-> sure
2013-10-25T14:38:10 < jpa-> keeps me sane
2013-10-25T14:38:15 < jpa-> (r)
2013-10-25T14:40:44 < zyp> missing half the lines of a conversation doesn't sound really sane
2013-10-25T14:44:02 < dongs> im more curious whos on ignore
2013-10-25T14:44:21  * karlp too.  such gossip ;)
2013-10-25T14:44:23 < dongs> i've /fakeignored a number of people in here but i cant really imagine anyone i'd want gone off my chats for real
2013-10-25T14:44:44 < Steffanx> true karlp, even when you know what "hsip" means it doesn't make sense, but as i didn't know what it meant i asked
2013-10-25T14:44:49 < Steffanx> guess i'll never try again.
2013-10-25T14:45:17 < dongie> Steffanx: the concept is called "lurk moar"
2013-10-25T14:45:23 < dongs> jpa-, I have put you on a permanent ignore, public and private. I have found you disturbing, rude and generally not worth talking to. According to the channels you hang on, it strengtens the effect of wanting to put you on ignore because of my lack of interest in you as a person. This message is not meant to be rude to you, just to inform you that i won't see anything of what you type from now on.
2013-10-25T14:45:40 < dongie> my typing is generally horrible and these kinda 2-adjacent transliterations are common
2013-10-25T14:46:09 < jpa-> dongs, I'll keep watching you nevertheless
2013-10-25T14:46:12 < Steffanx> ( i googled it before i asked, but google doesn't know your fails )

2013-10-25T21:03:28 < emeb> STM32 I2C peripheral requires a lot of management from sw
2013-10-25T21:03:42 < gxti> i2c is not confusing. stm32 i2c is annoying.
2013-10-25T21:03:47 < emeb> stepping through the various bus states, etc.
2013-10-25T21:05:04 < gxti> basically forces you to do a full irq driver when all you wanted was something dumb and simple to read config on startup
2013-10-25T21:06:43 < fbs> i just want to send 1 byte to a i2c io expander
2013-10-25T21:06:56 < fbs> and read 1
2013-10-25T21:06:57 < emeb> if you're just doing output it's a lot easier.
2013-10-25T21:07:32 < NooM> hmm i found it quite easy, but iam using a lib, mom ill paste code
2013-10-25T21:08:03 < gxti> i tried to do a 'simple' implementation and it hung, so i ended up ripping and then later rewriting Laurenceb's code
2013-10-25T21:08:10 < gxti> and somehow nothing has caught fire
2013-10-25T21:08:18 < emeb> hah
2013-10-25T21:08:34 < gxti> it's probably broken but works well enough for the trivial stuff i'm doing
2013-10-25T21:08:49 < emeb> the eval board eeprom code is all busywait / polled. works fine w/o IRQs.
2013-10-25T21:09:02 < fbs> well the io expander is going from all high to all low
2013-10-25T21:09:05 < fbs> so its doing something
2013-10-25T21:09:05 < NooM> http://pastebin.com/d3KUSQWN
2013-10-25T21:09:14 < gxti> i wasn't tickling the statemachine in just the right way, i'm sure you could make it polled if you really wanted to
2013-10-25T21:09:22 < gxti> really stupid shit though, it shouldn't do it that way
2013-10-25T21:09:25 < NooM> thats how i read data from adxl 345 (or whatever version number)
2013-10-25T21:09:29 < emeb> ya
2013-10-25T21:09:47 < emeb> compared to, say PIC I2C implementation it's a clusterfuck.
2013-10-25T21:10:03 < NooM> i havent wrapped all function in the nice class yet, cos its not that important to me :D
2013-10-25T21:10:07 < gxti> pic lets you do dumb shit but at least you don't have to read all the registers in just the right order to make progress
2013-10-25T21:10:18 < emeb> yep
2013-10-25T21:10:52 < gxti> oh and there's all the timing shit where depending on the size of the transaction you have to do different things
2013-10-25T21:11:07 < emeb> ugh

2013-10-25T21:26:05 < emeb> how did you do that?
2013-10-25T21:26:18 < emeb> and what's an stm32f497?
2013-10-25T21:26:39 < jpa-> fbs: what's up with the fan?
2013-10-25T21:26:54 < NooM> i took a mp3 file, made it to wav, 8 bit 16khz, copied the hex data to a .h file and played it with the dac :D
2013-10-25T21:26:57 < NooM> 407*
2013-10-25T21:27:05 < NooM> 9 was a typo

2013-10-25T21:29:18 < emeb> How can you tell with dubstep? :P
2013-10-25T21:29:19 < NooM> sadly 41khz doesent work well, guess my chepo amplifier dont like that
2013-10-25T21:29:24 < NooM> haha :D
2013-10-25T21:29:50 < emeb> The on-chip DACs aren't bad.

2013-10-25T22:10:14 < gxti> hey, it took me like a month to find one bug that caused my shit to work until i power cycled it
2013-10-25T22:10:40 < gxti> the new code wasn't initializing the ethernet PHY correctly, but i hadn't power cycled the board since writing it
2013-10-25T22:10:44 < zyp> emeb, does it work at all? :p
2013-10-25T22:11:07 < gxti> turns out that telling the PHY to reset itself isn't the same as pulling its reset line
2013-10-25T22:11:16 < emeb> zyp: it worked for a while this morning, now it's hanging when it tries to read from the eeprom.
2013-10-25T22:11:29 < zyp> I mean, Laurenceb's code :p
2013-10-25T22:11:55 < emeb> zyp: haven't tried it yet.
2013-10-25T22:12:22 < fbs> hmm i2c device getting stuck would be bad
2013-10-25T22:13:00 < emeb> anyone got a linky to the Laurenceb i2c?
2013-10-25T22:14:31 < gxti> here's my "rewrite" of it: https://github.com/mtharp/laureline-firmware/blob/master/src/eeprom.c although be warned that everything outside of the basic eeprom functions at the end is untested
2013-10-25T22:15:06 < emeb> thx
2013-10-25T22:15:39 < zyp> isn't Laurenceb doing F1-only?
2013-10-25T22:15:50 < gxti> that's true, that ^ is for f1
2013-10-25T22:16:43 < emeb> gxti: ok - will bear that in mind.

2013-10-26T00:23:03 < Tectu> "Both the heap buffer base and the heap size must be aligned to the stkalign_t type size."
2013-10-26T00:23:05 < Tectu> how would one do that?
2013-10-26T00:31:45 < zyp> uh
2013-10-26T00:31:57 < zyp> what do you mean «how»?
2013-10-26T00:32:04 < zyp> how do you allocate it?
2013-10-26T00:34:34 < Tectu> no, I'm really not sure how to make sure that the buffer is alligned as the function expects it.
2013-10-26T00:34:37 < Tectu> it's from here:   http://chibios.sourceforge.net/html/group__heaps.html#ga7135c9ddbd1402a4a36ce44df948f4e4
2013-10-26T00:34:55 < Tectu> and stkalign_t is :    typedef struct {  uint8_t a[8]; } stkalign_t __attribute__((aligned(8)));
2013-10-26T00:38:12 < Tectu> zyp, chHeapInit(&ext_heap, (void*)0x60000000, RAM_SIZE);   that's what I got.
2013-10-26T00:38:38 < Tectu> (it's an external 512kB SRAM)
2013-10-26T00:39:27 < zyp> ok
2013-10-26T00:39:34 < zyp> do you know what «aligned» means?
2013-10-26T00:40:03 < Tectu> yes, I think so
2013-10-26T00:40:13 < Tectu> but I probably won't meet the proper definition ;)

2013-10-26T00:40:51 < zyp> when addr x is aligned to size y, it means that x%y would be 0
2013-10-26T00:41:09 < Tectu> agreed
2013-10-26T00:41:16 < zyp> 0x60000000 is certainly aligned to 8 :p
2013-10-26T00:41:51 < zyp> 0x60000000 is aligned to every power of 2 up to and including 0x20000000 :p
2013-10-26T00:42:10 < Tectu> okay
2013-10-26T00:43:21 < Tectu> zyp, but it says I have to allign the second and third argument of chHeapInit() to stkalign_t type size
2013-10-26T00:43:29 < Tectu> I'm not sure what that means / how to archive that
2013-10-26T00:43:44 < Tectu> stkalign_t type size is equal to   sizeof(stkalign_t)  ?
2013-10-26T00:43:56 < zyp> yes
2013-10-26T00:44:02 < zyp> which is 8
2013-10-26T00:44:30 < Tectu> through the   unint8_t a[8] or the aligned(8) attribute  ?
2013-10-26T00:44:53 < zyp> you have a struct of 8 bytes, that means the size of that struct is 8 bytes
2013-10-26T00:44:58 < zyp> so the former
2013-10-26T00:45:25 < zyp> the latter is just a hint for the compiler/linker, telling it that it should align global instances of that object
2013-10-26T00:45:33 < zyp> global and stack
2013-10-26T00:45:47 < Tectu> so since 0x6000000 is aligned to 8 anyway, I don't have to care about that. I now have to make sure that the third, the size parameter is alligned to 8 as well, right?
2013-10-26T00:45:57 < zyp> yes
2013-10-26T00:46:18 < Tectu> for example 10240  <--- I'll get a 10k Heap from my external RAM
2013-10-26T00:46:32 < zyp> yep
2013-10-26T00:46:35 < Tectu> hmm
2013-10-26T00:47:06 < Tectu> I have a weird problem here... When I give it a size of 1024, I can allocate from it successfully. but with 10240, I get a NULL pointer back when I try to allocate from the new heap
2013-10-26T00:47:11 < Tectu> but the RAM itself has 512k :<
2013-10-26T00:50:10 < Tectu> zyp, when I create a heap of 1024, then allocate some portion of it, it actually starts at  0x60000008 where I expected 0x60000000... how comes that?
2013-10-26T00:50:36 < zyp> because the heap uses some of the memory to keep track of allocations
2013-10-26T00:51:10 < Tectu> aah, "the heap table"?
2013-10-26T00:51:42 < Tectu> that finally explains and fixes my issue... I tried to allocate a 10240 buffer from the 10240 heap :P
2013-10-26T00:53:22 < Tectu> zyp, I thank you very much for your help.
2013-10-26T00:55:05 < fbs> :)
2013-10-26T00:56:31 < fbs> anyone tried multimaster mode for spi? The controller hs to be able to request some data from the rpi, like time
2013-10-26T00:56:40 < fbs> but the rpi needs to be able to request temperature data
2013-10-26T00:57:05 < fbs> it needs to be teh spi port
2013-10-26T00:57:14 < Tectu> zyp, how would I allign something properly? I assume there's some non-manual way?
2013-10-26T00:58:10 < zyp> when you're typing in the addr manually, then you align it manually

2013-10-26T00:59:11 < Tectu> I read something about aligning buffers using unions with the to-align datatype
2013-10-26T00:59:50 < zyp> and then if you just need to align some number programmatically then you have to round the number up or down to the nearest fitting value
2013-10-26T01:00:34 < zyp> if you're aligning to 8 then you can do (x & ~7) to round down and ((x + 7) & ~7) to round up

2013-10-26T01:01:16 < zyp> this works for every n = 2**x, just substitute 7 for (n-1)
2013-10-26T01:04:08 < Tectu> okay, finally this RAM works
2013-10-26T01:04:11 < Tectu> thanks again.

2013-10-26T01:27:22 < gxti> first under-$100 digikey order in a while...but only because f429disco is out of stock
2013-10-26T01:28:01 < zyp> you don't get free shipping from digikey?
2013-10-26T01:28:18 < gxti> not in the US. it's kind of nonsensical when you think about it.

2013-10-26T01:29:07 < zyp> how much is shipping usually then?
2013-10-26T01:29:34 < Laurenceb_> i can get next day shipping from virtually anywhere now :P
2013-10-26T01:29:55 < Laurenceb_> i'm 4miles from major DHL hub
2013-10-26T01:30:24 < gxti> $12-ish, pretty typical ground shipping
2013-10-26T01:30:31 < dongs> zyp they hide the cheap shipping
2013-10-26T01:30:32 < zyp> ah, ok
2013-10-26T01:30:43 < zyp> it's $30 or so to norway, I believe
2013-10-26T01:30:47 < dongs> see he couldnt find it
2013-10-26T01:30:59 < zyp> but free when I hit $90 or so
2013-10-26T01:31:07 < Laurenceb_> it seems to depend a lot more on their hub setup than physical distance
2013-10-26T01:32:24 < gxti> i think usps is less, i haven't really used them much for packages in the past but maybe i should
2013-10-26T01:32:37 < gxti> the cutoff time for ups/fedex is later so maybe that's why i use them
2013-10-26T01:33:39 < emeb> gxti: I always get the USPS priority - usually gets 2day shipping for ~$5
2013-10-26T01:34:29 < gxti> hmm, the cutoff times are all the same now. so there goes that reason.
2013-10-26T01:35:51 < emeb> best trick is to order Friday, get it Monday.
2013-10-26T01:38:08 < gxti> done. bought the last 3 of the tcxo i was using, which have been at 3 stock for like a month.

2013-10-26T01:39:37 < dongs> clearly a sign you shouldn't be using them
2013-10-26T01:39:54 < gxti> doesn't matter, i can use any tcxo with that footprint and voltage
2013-10-26T01:41:03 < gxti> of which there are a dozen different part numbers with thousands in stock. but these are the cheapest.
2013-10-26T01:44:06 < gxti> in fact all my clock calculations are done in software so i can have it autodetect on boot

2013-10-26T14:29:04 < jpa-> Robint91: isn't there already an ST appnote on uclinuc?
2013-10-26T14:29:08 < jpa-> *uclinux
2013-10-26T14:29:27 < Robint91> jpa-, it is a fairly old kernal
2013-10-26T14:29:34 < jpa-> true
2013-10-26T14:29:48 < Robint91> jpa-, my idea is to replicate http://www.linux-arm.org/LinuxKernel/LinuxM3
2013-10-26T14:29:53 < Robint91> with a newer kernel
2013-10-26T14:30:38 < Robint91> and then add stm32f42x support
2013-10-26T14:38:39 < Robint91> jpa-, mhh
2013-10-26T14:38:55 < Robint91> jpa-, those patches are in the mainline
2013-10-26T14:38:56 < Tectu> The STM32F407 only support 8 and 16-bit mode SPI, right?
2013-10-26T14:39:05 < Tectu> I've some Nokia6610 display here which would like 9-bit mode
2013-10-26T14:39:11 < zyp> no
2013-10-26T14:39:13 < Tectu> can the STM handle 8-bit + control bit?
2013-10-26T14:39:25 < zyp> sure, it supports anything up to 16
2013-10-26T14:39:57 < Tectu> RM says:
2013-10-26T14:39:57 < Tectu> ● Data format may be 16-bit, 24-bit or 32-bit
2013-10-26T14:39:58 < Tectu> ● Packet frame is fixed to 16-bit (16-bit data frame) or 32-bit (16-bit, 24-bit, 32-bit data
2013-10-26T14:39:58 < Tectu> frame) by audio channel
2013-10-26T14:41:35 < Tectu> zyp, and figure 273 also tells you:   8 or 16 bits depending on the Data frame format bit (see DFF in SPI_CR1)
2013-10-26T14:41:39 < Tectu> on the MOSI line
2013-10-26T14:41:44 < Tectu> I don't think it can do 9-bit
2013-10-26T14:42:48 < zyp> 13:39:58 < Tectu> ● Data format may be 16-bit, 24-bit or 32-bit
2013-10-26T14:42:53 < zyp> that's for I2S mode
2013-10-26T14:43:13 < Tectu> can you check Fig. 273?
2013-10-26T14:43:16 < Tectu> (RM 0090)
2013-10-26T14:43:23 < Tectu> page 800 here
2013-10-26T14:43:34 < zyp> um, it's not in rev 5 :p
2013-10-26T14:43:41 < Tectu> lol?
2013-10-26T14:43:48 < Tectu> I have Rev 4
2013-10-26T14:43:53 < zyp> your problem
2013-10-26T14:44:17 < Tectu> you say the new RM meniones 9-bit mode? ;-)
2013-10-26T14:44:33 < zyp> no, I say that there is no fig 273 on page 800 here
2013-10-26T14:44:45 < zyp> so I have no idea what you're referring to
2013-10-26T14:44:56 < Tectu> rev 5 now
2013-10-26T14:45:39 < Tectu> zyp, fig. 245 on page 858
2013-10-26T14:45:56 < zyp> wtf
2013-10-26T14:46:07 < zyp> you're right, F4 doesn't support other sizes than 8 and 16
2013-10-26T14:46:10 < zyp> F3 does.
2013-10-26T14:46:39 < zyp> F3 has a DS field in CR2 tht sets the number of bits, that field is apparently not present in F4
2013-10-26T14:47:14 < Tectu> wow, that feeling... being right in an argument with zyp :P
2013-10-26T14:47:26 < zyp> congratulations
2013-10-26T14:47:29 < Tectu> so how am I supposed to talk to the Nokia6610?
2013-10-26T14:47:34 < Tectu> it's on an olimex p407 board
2013-10-26T14:47:42 < Tectu> they wouldn't have put it there when it wouldn't be possible :P
2013-10-26T14:47:51 < Robint91> Tectu, bitbang?
2013-10-26T14:47:58 < Robint91> or use the usart
2013-10-26T14:48:27 < jpa-> you can always pack the bits
2013-10-26T14:49:18 < jpa-> and Robint91 is right, the USART supports 9 bits, so it is good if the pins match
2013-10-26T14:49:50 < Tectu> oh dear
2013-10-26T14:51:21 < Tectu> R2COM, that's somehow sad, no? Shouldn't the purpose of such a channel exactly be the opposit of that?
2013-10-26T14:53:00 < zyp> R2COM can't handle the fact that people doesn't remember all the differences between the different chip families and may make wrong assumptions on different families behaving in the same way
2013-10-26T14:53:57 < Tectu> zyp, I don't think he refered to you here
2013-10-26T14:54:19 < Tectu> at least you didn't act that way, in my opinionn
2013-10-26T14:54:45 < Tectu> you people are right, btw.... olimex bitbanged the controller using GPIO
2013-10-26T14:54:59 < zyp> dunno, I was the one that gave you the wrong answer :p
2013-10-26T14:55:46 < Tectu> zyp, and? it wasn't arrogant in my opinion. the thing with the revision probably, but not the SPI thing :P
2013-10-26T14:57:19 < zyp> so anyway, who of you guys have been autogenerating usb serial numbers, and how did you do it?
2013-10-26T14:58:27 < jpa-> i just hashed the unique id and hoped that there would be no collisions in my lifetime :)
2013-10-26T14:58:55 < jpa-> ST also has some algorithm in their DFU bootloader.. i wonder if it is any good
2013-10-26T14:59:07 < zyp> I'm wondering how to hash it and how long the result should be
2013-10-26T14:59:08 < Tectu> ST software wasn't that good so far, I think
2013-10-26T14:59:22 < Tectu> but yes, software != algorithm
2013-10-26T14:59:47 < jpa-> zyp: you might also just take it as it is (only the significant bytes).. that way there won't be collisions
2013-10-26T15:00:19 < jpa-> Tectu: their quality is surprisingly varying.. one might even think that they have more than one group of programmers working there
2013-10-26T15:00:29 < zyp> yeah, unless there are some requirements on usb serial length
2013-10-26T15:00:30 < Robint91> jpa-, I use murmurhash64
2013-10-26T15:00:37 < Robint91> to generate 64bit IDS
2013-10-26T15:00:59 < zyp> IIRC there is no requirements in usb itself, but some classes have stricter requirements
2013-10-26T15:01:10 < jpa-> though at work we wantesensible serial numbers anyway, and put them in OTP
2013-10-26T15:01:12 < zyp> saying that the first n bytes have to be unique
2013-10-26T15:01:51 < Robint91> https://gist.github.com/anonymous/7168690
2013-10-26T15:01:58 < Robint91> ^ I use this

2013-10-26T15:18:40 < dongs> i have a feeling these are not rear entry specifically but might work since back is open
2013-10-26T15:19:10 < zyp> maybe

2013-10-26T15:19:31 < zyp> do the female ones have alignment pins between outer four holes on each end?

2013-10-26T15:20:37 < dongs> i just see rows of holes?

2013-10-26T15:21:09 < dongs> nope
2013-10-26T15:21:49 < zyp> dunno how easy it'll be to keep them aligned during reflow without
2013-10-26T15:22:40 < zyp> jpa-, true, but that doesn't sound like a huge risk :p
2013-10-26T15:24:12 < jpa-> zyp: i was doing something like that on STM32F4.. and one of the fields was 0 quite often, can't remember the details though
2013-10-26T15:24:34 < jpa-> probably would be obvious if you dig up the definition of the UID fields

2013-10-26T18:51:49 < dongs> is that the arab drone they caught couple yearsa ago
2013-10-26T18:51:49 < emeb_mac> a surprising number of people seem to think that their circuits are unique and wonderful and not to be shared.
2013-10-26T18:52:05 < dongs> ohh i see, he changed ARCHITECTURE
2013-10-26T18:52:10 < Laurenceb__> im thinking they are looking an lens distortion

2013-10-26T18:53:05 < gxti> yes, he changed architecture and the pcb looks exactly the same except black
2013-10-26T18:53:09 < dongs> fake pixels are called dixels

2013-10-26T18:53:18 < dongs> theyre in diff place
2013-10-26T18:53:20 < dongs> and he added resistors

2013-10-26T18:54:07 < gxti> did the footprint change?
2013-10-26T18:54:12 < dongs> afaik no
2013-10-26T18:54:22 < dongs> should be all standard for neo* stuffs
2013-10-26T18:54:24 < gxti> ok let's see what exciting new features it has
2013-10-26T18:54:30 < gxti> probably nothing i care about right now
2013-10-26T18:54:33 < dongs> realtime position twittering

2013-10-26T19:05:27 < dongs> so i see their trash in google ads etc.

2013-10-26T19:06:25 < dongs> what "production process"???
2013-10-26T19:06:31 < dongs> all i see is chinks unpacking bare LCD panesl
2013-10-26T19:06:37 <+dekar> "I'm aware that the Able-HD is far from perfect. Its main weakness is fragility. There is no external case or box to cover the adapter board. While any LED monitor will break when dropped, the Able-HD might be even more fragile as it does not have an external case to shield it. Improvements must be made in regards to this."

2013-10-26T20:02:09 < Robint91> it is difficult to get the kernel under 2MB
2013-10-26T20:04:18 < jpa-> do you have it compressed or execute-in-place?

2013-10-26T20:06:29 < Robint91> it is now 2.3MB
2013-10-26T20:06:42 < Robint91> but I see some room for improvement
2013-10-26T20:06:59 < Robint91> I want to get to 1.5MB
2013-10-26T20:07:09 < Robint91> so I have 512kb for the bootloader
2013-10-26T20:07:25 < jpa-> and 0 bytes for useful stuff? :)
2013-10-26T20:07:34 < jpa-> and what kind of a bootloader takes 512kB?
2013-10-26T20:07:53 < Robint91> jpa-, usefull stuff runs from SD of ext flash
2013-10-26T20:08:04 < Robint91> jpa-, depends on how the memory layout it
2013-10-26T20:08:06 < Robint91> *is
2013-10-26T20:09:11 < emeb_mac> hehe - uboot is huge. almost an OS unto itself.
2013-10-26T20:09:38 < Robint91> emeb_mac, I don't know if I'm going to use uboot
2013-10-26T20:09:42 < emeb_mac> device drivers, filesystems, command line. :P
2013-10-26T20:09:49 < gxti> every bootloader eventually becomes an OS
2013-10-26T20:10:14 < emeb_mac> kinda like zawinski's law.
2013-10-26T20:10:35 < gxti> grub2 is a cariacature of that law
2013-10-26T20:11:04 < Robint91> ^ SO MUCH THIS
2013-10-26T20:12:07 < Robint91> jpa-, just checked the memory layout
2013-10-26T20:12:17 < Robint91> I want 128kb for the bootloader
2013-10-26T20:12:20 < Robint91> everything else kernel
2013-10-26T20:15:40 < jpa-> humm.. does this board have high-speed usb or not? https://www.olimex.com/Products/ARM/ST/STM32-E407/   they say "USB OTG HS", but i don't see the PHY that is needed for HS..
2013-10-26T20:20:09 < Steffanx> doesn't look like it ..
2013-10-26T20:22:06 < madisx> schematic connects to PA11/OTG_FS_DM and PA12/OTG_FS_DP
2013-10-26T20:22:10 < madisx> whatever that is
2013-10-26T20:26:16 < jpa-> yeah, i guess the feature list is just wrong
2013-10-26T20:26:27 < jpa-> they are using OTG_HS but only in full-speed mode
2013-10-26T20:29:12 < Steffanx> mr Tectu wasnt happy with that board was that another one mr Tectu?
2013-10-26T20:29:19 < Steffanx> *or was
2013-10-26T20:29:49 < Tectu> the E407?
2013-10-26T20:29:54 < Tectu> That's completely fine
2013-10-26T20:30:00 < Tectu> jpa-, you can't use HS with that
2013-10-26T20:30:07 < Tectu> jpa-, it has the HS on a connector, but not the necessary driver for it
2013-10-26T20:30:16 < Tectu> (afaik you need the external HW to drive the HS, no?)
2013-10-26T20:30:29 < emeb_mac> phy!
2013-10-26T20:30:34 < Tectu> yep, and it doesn't have one

2013-10-27T00:12:32 < qyx_> hm, not bad
2013-10-27T00:12:34 < Robint91> I think I get under 1MB
2013-10-27T00:12:45 < Robint91> but you starting too loose nice stuff
2013-10-27T00:12:55 < Robint91> like dynamic loading of modules
2013-10-27T00:12:58 < Robint91> etc, etc

2013-10-27T00:13:27 < qyx_> how could you dynamically load module if kernel is running from flash and you don't have mmu?

2013-10-27T00:13:45 < Robint91> qyx_, you don't need a mmu
2013-10-27T00:14:05 < Robint91> qyx_, you just allocate RAM for your code and run from it there

2013-10-27T00:15:31 < jpa-> qyx_: kernel modules all go in kernel address space anyway, so they are relocatable
2013-10-27T00:15:38 < Robint91> qyx_, TCPI/IP is around 370kB, FS is 350kB, kernel 229kB, drivers 200kB,
2013-10-27T00:15:40 < qyx_> hm
2013-10-27T00:16:10 < jpa-> Robint91: which FS?
2013-10-27T00:16:30 < Robint91> jpa-, EXT2/EXT3/JFFS/VFAT
2013-10-27T00:16:39 < jpa-> why so many?
2013-10-27T00:16:57 < Robint91> jpa-, I can leave out EXT2/EXT3
2013-10-27T00:17:00 < Robint91> jpa-, to test
2013-10-27T00:18:46 < Steffanx> but does it actually run Robint91 .. ?
2013-10-27T00:18:59 < Robint91> Steffanx, no :)
2013-10-27T00:19:14 < Robint91> Steffanx, A) No hardware B) No drivers
2013-10-27T00:19:29 < Robint91> Steffanx, I wanted to check if the toolchain and kernel sources are okay

2013-10-27T00:23:28 < Robint91> jpa-, proof of concept
2013-10-27T00:24:05 < Robint91> jpa-, A) kernel calls are all flash based, so fast execution
2013-10-27T00:24:16 < Steffanx> qyx_, but compiling just a tiny kernel is no proof of concept ;)
2013-10-27T00:24:38 < Robint91> I don't think there is a large significant hit in using A) file system function B) networking
2013-10-27T00:25:06 < Steffanx> ok, it is a proof of something but ..
2013-10-27T00:25:39 < Robint91> Steffanx, it proofs to me that the mainline kernel has CORTEX-Mx support
2013-10-27T00:25:53 < Robint91> and that the linaro-gcc can do armv7m
2013-10-27T00:26:07 < Steffanx> No, it proofs to you it builds, not that it's actually useful ;)
2013-10-27T00:26:29 < Robint91> Steffanx, less work for me
2013-10-27T00:26:38 < Steffanx> but .. whatever, it's nice if it turns out it works

2013-10-27T01:30:39 < DanielHolth> Just got a STM32 board running a simple program
2013-10-27T01:30:58 < DanielHolth> Any hints on getting Eclipse's gdb hardware debugging plugin to work?
2013-10-27T01:43:22 < BrainDamage> you need a debug bridge
2013-10-27T01:44:41 < DanielHolth> oh
2013-10-27T01:45:00 < DanielHolth> I think I just need to add a few halt / etc. or "this is how to flash on the stm32" scripts?
2013-10-27T01:45:25 < BrainDamage> the 2nd
2013-10-27T01:45:46 < BrainDamage> as well, "this program talks to the hw debugger and exposes a gdb remote interface"
2013-10-27T01:46:06 < DanielHolth> I can flash with openocd now
2013-10-27T01:46:10 < BrainDamage> stlink from texane does the task, openocd too
2013-10-27T01:46:22 < BrainDamage> then you should be able to make it debug too
2013-10-27T01:46:51 < BrainDamage> there's commands to make open obsessive compulsive disorder to start a gdb remote server that eclipse can connect to
2013-10-27T01:47:30 < DanielHolth> i've got that part started

2013-10-27T02:49:12 < zyp> sure

2013-10-27T02:53:58 < Tectu> zyp, thanks. So I have some LCD and some SRAM connected to FSMC bank 1. the LCD is NE1 and the SRAM is NE2. Therefore the LCD starts at 0x60000000. That FSMC bank can actually manage four "devices" and is split into 4x 64Mbit. I assume that I simply have to access the address 0x600000 + 64MBit to access the SRAM. Is that correctly?
2013-10-27T02:54:06 < Tectu> I don't have to set any bits myself ot make NE2 work

2013-10-27T02:56:17 < zyp> ah, f429i-disco?
2013-10-27T02:56:39 < zyp> or f407?

2013-10-27T02:57:25 < Tectu> haha, sorry, wrong page :P
2013-10-27T02:57:46 < Tectu> page 1520 it is
2013-10-27T02:58:45 < zyp> apparently you have to set MBKEN in FSMC_BCRx for each of the banks
2013-10-27T02:59:44 < zyp> there is a set of three registers for each bank, so I guess you have to set up those correctly for each of the banks you want to use
2013-10-27T03:01:18 < zyp> when that is done, you should be able to just access 0x60000000, 0x64000000 and so on
2013-10-27T03:01:41 < Tectu> I see
2013-10-27T03:02:04 < Tectu> but the timings... are those per bank or per section of bank 1?
2013-10-27T03:02:27 < zyp> per subbank
2013-10-27T03:04:19 < Tectu> most likely I missed the MBKEN for the second bank then

2013-10-27T03:18:27 < Tectu> not any memory
2013-10-27T03:19:05 < qyx_> if you overwrite your stack and then return from a function, you can get that value to your pc

2013-10-27T04:58:53 < emeb_mac> anyone here ever programmed flash from within running code?
2013-10-27T05:07:41 < talsit> as in, writing code to write to flash?
2013-10-27T05:23:58 < madist> never done it, but I assume it must be hell. you'd have to buffer up a block in some other memory before doing the flash write ?
2013-10-27T05:25:08 < talsit> there's an app note on how to emulate eeprom in flash
2013-10-27T05:25:55 < talsit> http://www.stm32f0.com.cn/pdfs/application_note/AN4061.pdf
2013-10-27T05:26:57 < madist> .com.cn ?
2013-10-27T05:28:45 < talsit> it's what google gave me
2013-10-27T05:30:26 < madist> 266,060 bytes. the one from st.com is 265,819 bytes.
2013-10-27T05:31:03 < madist> though I guess that doesn't mean anything. acrobat reader rebuilds a pdf every time you save a local copy.
2013-10-27T05:32:36 < emeb_mac> yeah - I've seen that appnote before
2013-10-27T05:33:28 < emeb_mac> I've got a huge data array in flash and I need to update chunks of it from time to time
2013-10-27T05:34:26 < madist> lolz
2013-10-27T05:35:13 < emeb_mac> main issue is that the flash write code needs to run from SRAM since flash is unavailable during erase/pgm
2013-10-27T05:36:07 < dongs> emeb_mac: um yeah? you mean just to flash some settings/etc?
2013-10-27T05:36:20 < dongs> huh is it?
2013-10-27T05:36:26 < dongs> i dont run flash code from sram
2013-10-27T05:37:05 < emeb_mac> oh?
2013-10-27T05:37:30 < dongs> https://code.google.com/p/afrodevices/source/browse/trunk/baseflight/src/config.c#90 F1 but same principle on *
2013-10-27T05:39:12 < emeb_mac> interesting
2013-10-27T05:39:30 < dongs> it works perfectly fine, even while other shit is running etc.
2013-10-27T05:39:32 < emeb_mac> so the processor just pauses while the flash is unavailable I guess
2013-10-27T05:40:03 < emeb_mac> you don't shut down IRQs, DMA, etc?
2013-10-27T05:40:19 < dongs> no, but that shit isn't threaded anyway, so its just there while it runs.
2013-10-27T05:40:35 < dongs> but no i dont touch irqs
2013-10-27T05:40:37 < dongs> which could happen I guess
2013-10-27T05:40:40 < dongs> serial etc.
2013-10-27T05:40:46 < dongs> and it hasnt been a problem.
2013-10-27T05:41:17 < emeb_mac> well then - that's easier than I thought.
2013-10-27T05:41:40 < dongs> i think the ram stuff is to update the code you're running FROM
2013-10-27T05:41:54 < dongs> if youre updating the bootlodaer or osmeshit.
2013-10-27T05:41:59 < emeb_mac> I was thinking I'd have to gracefully turn off all DMA, IRQs, etc while programming flash. That'd be a pain
2013-10-27T05:42:10 < dongs> i don't and it hasnt affected me.
2013-10-27T05:42:19 < emeb_mac> but I'm just updating a big array of const data
2013-10-27T05:42:48 < emeb_mac> dongs: cool - that's good info. I can try this the simple way and see what happens.
2013-10-27T05:44:33 < emeb_mac> if that works then the only thing I need to do is align the data array onto a 2k boundary so it matches the flash page.
2013-10-27T05:45:49 < dongs> 1k or 2k or whatever depending ondevice
2013-10-27T05:45:54 < emeb_mac> right
2013-10-27T05:45:55 < dongs> also different flash banks on F4 are diff size
2013-10-27T05:46:01 < dongs> i think top bank of F4 is like 16k/page
2013-10-27T05:46:19 < emeb_mac> yeah, this is an F303. a bit simpler
2013-10-27T05:46:21 < dongs> wait wadayoumean "aligned"
2013-10-27T05:46:35 < dongs> just write it raw @ sector  boundary, like top of hte flash
2013-10-27T05:46:49 < dongs> then craparray *lol = FLASH_END-2K

2013-10-27T05:47:04 < emeb_mac> that would work too
2013-10-27T05:47:04 < dongs> i suppose you could force it to be there w/linker script
2013-10-27T05:47:13 < dongs> if you wanna have some defaults in
2013-10-27T05:47:41 < emeb_mac> but aligned should be pretty easy to do - just a compiler attrib on the array declaration.
2013-10-27T05:57:03 <+dekar> emeb_mac, I can confirm that execution just halts during flash erase while running from flash, it continues gracefully once it's done.
2013-10-27T05:57:43 < emeb_mac> dekar: thanks - that just what I want to hear.
2013-10-27T05:58:23 < emeb_mac> looks like the main thing to be sure that HSI is running.

2013-10-27T14:11:44 < Tectu> zyp, can the BMP handle a connect-under-reset?
2013-10-27T14:12:25 < zyp> handle?
2013-10-27T14:13:02 < jpa-> do
2013-10-27T14:13:40 < jpa-> tectu's board is crashing so fast that he can't connect using BMP :)
2013-10-27T14:15:10 < Tectu> :P
2013-10-27T14:15:34 < dongs> haha
2013-10-27T14:16:30 < jpa-> it always amazes me how rarely people run into that, even though it is pretty easy to cause.. just mess up oscillator, GPIO or sleep mode right after boot
2013-10-27T14:17:25 < jpa-> Tectu: if BMP cannot do it, you can do it with stlink.. v2 can do it itself, and with v1 + texane + manual reset button it is pretty easy also
2013-10-27T14:17:34 < jpa-> other way is to restore through BOOT0 bootloader
2013-10-27T14:17:52 < Tectu> too bad I didn't add any connector for the JTAG
2013-10-27T14:18:01 < Tectu> yeah, I could use the DFU
2013-10-27T14:18:11 < Tectu> let's see if zyp replies, probably we can soft-fix this
2013-10-27T14:19:08 < zyp> last time I checked bmp didn't have code for driving reset, but it may have changed since, as people were talking about adding it
2013-10-27T14:20:03 < zyp> I'm a bit busy testing stuff right now
2013-10-27T14:20:05 < zyp> :p

2013-10-27T14:20:42 < Robint91> nice
2013-10-27T14:20:58 < fbs>  whats a bmp?
2013-10-27T14:21:08 < zyp> blackmagic probe
2013-10-27T14:21:09 < Tectu> what's that?
2013-10-27T14:21:13 < Tectu> fbs, some fancy JTAG
2013-10-27T14:21:19 < fbs> zyp: is that a tagconnect?
2013-10-27T14:21:27 < Tectu> zyp, oh, you got the tagconnectors!!
2013-10-27T14:21:28 < Tectu> heh
2013-10-27T14:21:30 < zyp> yep, and the board it's hooked to is a bmp
2013-10-27T14:22:03 < Tectu> I like your USB hubs
2013-10-27T14:22:07 < dongs> sup PROS
2013-10-27T14:22:24 < zyp> both bootloader stuff and automated testing stuff works fine :)

2013-10-27T14:23:13 < zyp> so far one board out of 15 has failed
2013-10-27T14:23:24 < dongs> whats wrong with it?
2013-10-27T14:23:26 < zyp> probably just a simple short somewhere, will look at it later
2013-10-27T14:23:29 < dongs> ah
2013-10-27T14:24:19 < zyp> hmm, can't see any obvious shorts when looking at it
2013-10-27T14:26:16 < jpa-> Tectu: looking at the BMP source code, maybe    "monitor connect_srst enable"    would work
2013-10-27T14:27:54 < Tectu> just checked the schematics - at least I connected the RST
2013-10-27T14:27:55 < Tectu> NRST*
2013-10-27T14:29:33 < Tectu> jpa-, well, I see the device through   monitor jtag_scan  when I hold down the reset button, but I cannot connect to it using   attach 1
2013-10-27T14:29:41 < Tectu> executing   mon  connect_srst enable   first didn't help either

2013-10-27T16:16:47 < NooM> hey guys i have a very weird problem, maybe someone has ideas how to solve it. iam using c++. soo, thats my main.cpp: http://pastebin.com/EkcPp5vt
2013-10-27T16:17:02 < NooM> if i uncomment the adc_1 pointer all works fine
2013-10-27T16:17:10 < NooM> (i mean, remove it)
2013-10-27T16:17:19 < NooM> but if its there, the dma stops to work
2013-10-27T16:17:31 < NooM> (it no matter if its allocated/initialized or not)
2013-10-27T16:17:54 < jpa-> you're probably overwriting random parts of memory somewhere
2013-10-27T16:18:01 < NooM> if i remove all the code for the void UpdateDisplay() it works again
2013-10-27T16:18:11 < NooM> (just the code inside i mean)
2013-10-27T16:18:26 < jpa-> how does the dma stop working?
2013-10-27T16:18:30 < NooM> the timer do9esent crash btw
2013-10-27T16:18:48 < NooM> jpa- well nothing happens, both displays freeze
2013-10-27T16:18:52 < NooM> its so weird
2013-10-27T16:20:01 < jpa-> does it go to hardfault? does the code just keep waiting for dma to finish? does the dma NDTR register change?
2013-10-27T16:20:07 < NooM> and i cant see anything suspßicious in the debugger, it keeps running through the loop
2013-10-27T16:20:50 < NooM> how do i check this ndtr register ?

2013-10-27T18:09:00 < bsdfox> I'm working on a 1-wire driver using the uart peripheral but when I change baud rate (disable UE bit, set BRR, set UE bit) I get a glitch where the line is pulled low for 1.75us .  The datasheet says the status register is cleared when UE is disabled.. is there a good workaround for this or perhaps some way to change the baud rate without driving the line low?
2013-10-27T18:09:58 < qyx_> you can set gpio to AF mode after setting correct baudrate
2013-10-27T18:10:15 < qyx_> but 1.75us shouldn't be a problem for 1wire
2013-10-27T18:17:46 < bsdfox> perhaps it's not but my logic analyzer doesn't like it :) clearing TE / MODER don't seem to make a difference hmm

2013-10-27T18:54:00 < PaulFertser> Tectu: I've mostly implemented and tested connect_srst in BMP myself, so if you still have issues with it, let's investigate. For swdp_scan the effect should be exactly the same as if you were holding the button. If it doesn't work without the button, please tell me what bmp target and sources revision you're using.
2013-10-27T18:54:08 < Laurenceb__> wow i didnt know the effect was that bad
2013-10-27T18:54:32 < Tectu> PaulFertser, I just leave for dinner, I'll be back in 20 minutes or so. Thanks for your help so far!

2013-10-27T18:56:41 < PaulFertser> gxti: any tips? Should one just choose higher voltage X7R ones (as in, 50V cap for filtering 5V output)?
2013-10-27T18:57:38 < gxti> use physically bigger ones.
2013-10-27T18:57:52 < gxti> the voltage rating does not correlate much.
2013-10-27T18:59:12 < PaulFertser> gxti: is there any rule of thumb probably?
2013-10-27T18:59:16 < gxti> my current favorite big ceramic cap is 4.7uF 10V X7R 0805, less than 20% lost at 5v if i remember right
2013-10-27T18:59:57 < gxti> it can be very tricky to actually find the right chart, usually the datasheet does not have it :(
2013-10-27T19:00:11 < madist> isn't it easier just to use 1206 parts ?
2013-10-27T19:00:19 < madist> or even tantalum caps
2013-10-27T19:00:25 < gxti> tantalums are cancer
2013-10-27T19:00:30 < madist> nonsense
2013-10-27T19:00:34 < gxti> but sure you can always just use the biggest cap you can find :p
2013-10-27T19:00:34 < madist> I've never had one blow up
2013-10-27T19:01:36 < PaulFertser> We had plenty of tantalums blowing up, due to excessive voltage or wrong polarity.
2013-10-27T19:01:42 < gxti> madist has never had a tantalum blow up guys, it's ok use them all you want
2013-10-27T19:02:26 < PaulFertser> One "smart" fellow here even tried using them in series to fake voltage rating or something like that, no wonder that wasn't stable.
2013-10-27T19:02:52 < gxti> with balancing resistors i hope. still a dumb idea.
2013-10-27T19:03:38 < PaulFertser> afaik, no :)
2013-10-27T19:04:08 < gxti> without resistors the one with a slightly higher esr gets all the volts and explodes :p
2013-10-27T19:05:49 < PaulFertser> Exactly
2013-10-27T19:06:45 < gxti> anyway, i use these like candy: http://www.yuden.co.jp/ut/product/category/capacitor/LMK212B7475KG-T.html
2013-10-27T19:07:02 < gxti> digikey links to the abbreviated datasheet without charts for pretty much all caps unfortunately
2013-10-27T19:07:16 < gxti> but some (not most) manufacturers have the data published
2013-10-27T19:07:46 < gxti> you can see that one is -20% at 3.3v and -30% at 5v, which is relatively good. you could up the size to 1206 and get even better.
2013-10-27T19:08:28 < PaulFertser> gxti: thank you!

2013-10-27T19:08:51 < gxti> the only rule of thumb is that bigger is better, and voltage rating is irrelevant (although obviously don't use an underrated cap)
2013-10-27T19:09:09 < madist> check out the capacitance vs frequency ...
2013-10-27T19:09:40 < madist> can't use these caps beyond 1MHz
2013-10-27T19:09:52 < PaulFertser> gxti: i've clearly seen it in one datasheet (don't remember atm) that those with the higher voltage rating had less capacity loss...

2013-10-27T19:09:57 < Laurenceb__> wtf
2013-10-27T19:10:02 < gxti> that's typical resonance behavior
2013-10-27T19:10:17 < gxti> but yes, you wouldn't want to use it past the resonant frequency (which is true of all caps)
2013-10-27T19:10:25 < madist> 1MHz is kind of low
2013-10-27T19:11:27 < gxti> looks more like 5-ish
2013-10-27T19:12:10 < gxti> but yeah, big caps have more inductance so that becomes an issue. so if you can't get the capacitance you need at the voltage you need with the resonant frequency high enough... time to switch to polymer!
2013-10-27T19:12:47 < madist> its not the size. its the length vs width
2013-10-27T19:13:26 < gxti> Laurenceb__: that looks inefficient
2013-10-27T19:14:40 < gxti> http://psearch.murata.com/capacitor/product/GRM31CR71A475KA01#.html
2013-10-27T19:15:05 < gxti> 2012 size, only -5% at 5V. but resonant freq is worse.

2013-10-27T20:58:10 < Steffanx> good point
2013-10-27T20:58:39 < emeb_mac> Once GT started handling japanese and chinese, I figured that the singularity was here.
2013-10-27T20:58:51 < BrainDamage> i was more interested about the paint version, because there's a large price gap
2013-10-27T20:58:58 < BrainDamage> then again, the paint is messier to handle
2013-10-27T20:59:03 < BrainDamage> requires pre-drying
2013-10-27T20:59:12 < emeb_mac> how is the paint applied?
2013-10-27T20:59:37 < BrainDamage> rolled on, or spin coated for what I saw
2013-10-27T20:59:49 < BrainDamage> then pre-dried in oven
2013-10-27T20:59:59 < BrainDamage> then exposed, but even then, it's still partially wet
2013-10-27T21:00:10 < BrainDamage> which makes direct-on masking a pain
2013-10-27T21:00:11 < Tectu> Steffanx, I could translate

2013-10-27T21:10:52 < BrainDamage> that type is meant more to do do small touchups rather than actually coating a new board

2013-10-27T21:11:24 < emeb_mac> oh yeah - I've got a little solder mask pen with green goo in it. Works great.

2013-10-27T21:41:14 < Robint91> or are the diff between those
2013-10-27T21:41:34 < zyp> two times dwc_otg, instanced with a few differences
2013-10-27T21:41:59 < zyp> FS have three endpoint pairs in addition to control, HS have five
2013-10-27T21:42:13 < zyp> FS have 1.5kB of fifo mem (IIRC), HS have 4kB
2013-10-27T21:42:21 < zyp> also, HS have DMA
2013-10-27T21:42:36 < zyp> and then HS also have HS mode, of course ;)
2013-10-27T21:43:02  * Robint91 is making notes
2013-10-27T21:43:57 < zyp> also phy selection
2013-10-27T21:44:57 < zyp> I think the main gotcha when trying to use code written for the FS peripheral on the HS peripheral is that it defaults to external phy, and you have to explicitly select the internal one
2013-10-27T21:45:06 < zyp> I remember getting stuck on that

2013-10-28T11:00:44 < emeb_mac> what do you mean?
2013-10-28T11:00:44 < emeb_mac> clock speed? access times?
2013-10-28T11:02:15 < dongs> dong speed
2013-10-28T11:04:27 < zyp> throughput perhaps?

2013-10-28T11:47:04 < dongs> i wonder what they used in chromebook dixel
2013-10-28T11:48:13 < Robint91> dongs, have you found those panels?
2013-10-28T11:54:39 < Robint91> dongs, you seem to get easily to displays
2013-10-28T11:56:21 < dongs> yeah i have one here.

2013-10-28T11:58:43 < dongs> yeah
2013-10-28T11:58:50 < dongs> this shit happen to me a couple times few years ago
2013-10-28T11:58:56 < dongs> i'd add something to list
2013-10-28T11:59:04 < dongs> not notice it says "export controlled"
2013-10-28T11:59:08 < dongs> then order arrives
2013-10-28T11:59:09 < dongs> i WTF at where the shit is

2013-10-28T11:59:24 < dongs> which was fucking MADE in japan
2013-10-28T11:59:31 < dongs> but i couldnt fucking order it from digikey to ship to japan

2013-10-28T12:03:17 < dongs> it has gyro that can do > 1000 dps
2013-10-28T12:03:21 < dongs> which means you can put it in a missile
2013-10-28T12:06:43 < jpa-> also it has enough memory to store hello kitty images, and a screen to show them

2013-10-28T12:55:58 < Robint91> is there a nice list of STM32F4 pins
2013-10-28T12:56:23 < zyp> nicer than the datasheet?
2013-10-28T12:56:28 < Robint91> copying form that datasheet is BS
2013-10-28T12:56:41 < zyp> copying to what?
2013-10-28T12:56:53 < Robint91> some csv file
2013-10-28T12:57:01 < Robint91> so that altium can generate my symbol
2013-10-28T12:57:24 < fbs> Robint91: no vault access?
2013-10-28T12:57:32 < Robint91> fbs, no

2013-10-28T12:58:21 < fbs> the vault is bs anyway
2013-10-28T12:59:54 < fbs> Robint91: which one?
2013-10-28T13:00:05 < Robint91> STM32F4
2013-10-28T13:01:57 < fbs> there are quite a lot of versions
2013-10-28T13:02:10 < fbs> for some reason my vault access still seems to work, my trial ended 2 months ago

2013-10-28T13:20:18 < Robint91> karlp, nope does not work
2013-10-28T13:20:39 < Robint91> oh hai
2013-10-28T13:20:43 < Steffanx> like i said.. generate a list from that Robint91 ;)
2013-10-28T13:20:59 < ouah> so I'm using texane/stlink on mingw on a stm32l100 with 64 kB. My code is around 32 kB. texane/stlink takes 15 seconds to flash
2013-10-28T13:21:05 < Robint91> Steffanx, I hope that PSU pins are also included
2013-10-28T13:21:11 < ouah> I found that horribly slow
2013-10-28T13:21:18 < ouah> is there something I can do to speed up the process?
2013-10-28T13:21:26 < Steffanx> It is horrible slow ;)
2013-10-28T13:21:36 < Robint91> ouah, use a jlink
2013-10-28T13:21:47 < jpa-> ouah: it's faster for me.. though i'm on linux
2013-10-28T13:22:03 < fbs> 60k in 2 sec with the stlinkv2
2013-10-28T13:22:05 < jpa-> ouah: maybe try openocd? or the ST's own tool
2013-10-28T13:22:07 < ouah> I wonder if it is related to Windows, I should try with a Linux bux
2013-10-28T13:22:09 < ouah> box
2013-10-28T13:22:14 < Steffanx> ouah, why stlink/texane on windows and not openocb
2013-10-28T13:22:23 < Steffanx> uhm, what jpa- said
2013-10-28T13:22:45 < Steffanx> probably libusb-windows related?
2013-10-28T13:22:47 < ouah> well I heard that texane/stlink was faster ;)
2013-10-28T13:23:00 < Steffanx> on linux
2013-10-28T13:23:15 < ouah> Steffanx: in the same time STM32L1 has 256 bytes pages could be related
2013-10-28T13:23:20 < jpa-> haven't seen significant difference between openocd and texane on linux
2013-10-28T13:24:12 < ouah> but the Windows ST-Link tool from ST is is only a few seconds, not 15 s
2013-10-28T13:24:44 < jpa-> ouah: how old is that texane stlink version that you have?
2013-10-28T13:24:45 < Steffanx> if you want to have a GDB server you can also use the tool that comes with atollic studio

2013-10-28T13:34:08 < ouah_> Steffanx: the idea is the build machine is a Linux server, but the devs use a gdb-server (texane/stlink or openocd) on their Windows machine

2013-10-28T13:35:14 < Robint91> dongs, those things just work
2013-10-28T13:35:30 < Steffanx> ouah_, i was wondering why you need a gdb server on your build machine, i guess it does more that just compiling?
2013-10-28T13:35:42 < Steffanx> *building
2013-10-28T13:36:21 < Steffanx> whatever, not relevant :P

2013-10-28T13:37:16 < Steffanx> Ah.
2013-10-28T13:38:29 < jpa-> ouah_: from the texane/stlink output, you can see if the flash loader program is working or if it falls back to word-by-word writing
2013-10-28T13:38:46 < ouah_> jpa-: stlink log: http://pastebin.com/4dqAQPrR (notice that stdout and stderr are mixed in the output)
2013-10-28T13:38:58 < ouah_> jpa-: looks like it is writing page by page
2013-10-28T13:40:40 < jpa-> hmm.. i wonder why it comes across as separate requests for each page
2013-10-28T13:41:31 < jpa-> IIRC i usually see only one bunch of those messages
2013-10-28T13:42:18 < ouah_> I think I should try the Linux version and compare the output
2013-10-28T13:42:40 < ouah_> jpa-: did you ever tried with a STM32L1 ?
2013-10-28T13:42:53 < jpa-> yeah, i use stm32l1 most of the time
2013-10-28T13:43:05 < jpa-> though i usually flash with st-flash instead of through gdb
2013-10-28T13:43:25 < ouah_> I can also try st-flash to compare

2013-10-28T14:49:00 < ouah> jpa-: how long approximatively does a  "st-flash erase" takes?
2013-10-28T14:49:38 < jpa-> a few seconds IIRC
2013-10-28T14:49:39 < ouah> jpa-: on a Linux (in a VM) on my side it takes 62 seconds (L1 chip with 64 kB flash)...
2013-10-28T14:51:17 < jpa-> huh.. i've used texane in virtualbox without much trouble
2013-10-28T14:51:26 < jpa-> maybe the newest git version is broken once again ;)
2013-10-28T14:51:47 < Laurenceb> wtf
2013-10-28T14:51:58 < Laurenceb> i can erase an F1 in 9 seconds
2013-10-28T14:52:16 < PaulFertser> I flash L152 with openocd (without explicit erase), it takes several seconds.
2013-10-28T14:52:32 < Laurenceb> yeah
2013-10-28T14:53:48 < PaulFertser> L1 needs additional configuration right after reset to enable HSI and switch to it, then you can crank up jtag speed to 2MHz.
2013-10-28T14:54:22 < PaulFertser> (performed automatically when one does "reset init")
2013-10-28T14:57:02 < ouah> well I guess I should try also openocd, any link with a openocd "config" file for a STM32L1?
2013-10-28T14:57:13 < jpa-> comes with openocd
2013-10-28T14:57:20 < ouah> good:)
2013-10-28T14:57:33 < jpa-> i use   openocd -f interface/stlink-v1.cfg -f target/stm32lx_stlink.cfg
2013-10-28T14:58:25 < ouah> thx will try
2013-10-28T14:58:54 < zyp> 12:38:29 < jpa-> ouah_: from the texane/stlink output, you can see if the flash loader program is working or if it falls back to word-by-word writing
2013-10-28T14:58:57 < jpa-> (port for gdb is 3333)
2013-10-28T14:59:00 < zyp> does it even use a flashloader for L1?
2013-10-28T14:59:33 < jpa-> zyp: well atleast it says "Successfully loaded flash loader in sram"
2013-10-28T15:01:19 < zyp> when I wrote L1 support for bmp I figured using a flashloader wouldn't have any benefit, since L1 flash controller doesn't have any status bits that has to be polled between each word
2013-10-28T15:02:15 < jpa-> yeah.. the L1 flash controller is a bit funny, haven't studied the details

2013-10-28T15:43:06 < ouah> ok to flash a 33 kB FW on a L1:  texane/st-link on MinGW: flash time 16s, openocd on Linux (in a vm): 23s
2013-10-28T15:43:11 < ouah> that sux:)
2013-10-28T15:43:46 < Steffanx> time to try without a vm :)
2013-10-28T15:44:51 < ouah> I have the feeling this has nothing to do with the vm, but could be worth a try
2013-10-28T15:45:10 < fbs> is the v1 so much slower?
2013-10-28T15:45:13 < zyp> wonder how bmp would compare to that

2013-10-28T15:47:49 < zyp> you can't compare jtag adapters across families, f0 and l1 have completely different flash controllers
2013-10-28T15:48:52 < fbs> still 8x slower seems weird
2013-10-28T15:50:59 < ouah> zyp: in the present case I think it has nothing to do with the controller, using ST-Link tool from ST it is 3x faster with the L1

2013-10-28T15:58:35 < zyp> I think I saw the bootloader I wrote for F3 a few days ago do around 24 kB/s
2013-10-28T15:58:41 < qyx_> even with ftdi dongle i got similar speeds using openocd, so there's probably something very wrong if you get only ~3KB/s
2013-10-28T15:58:51 < zyp> and F3 is using the same flash controller as F1

2013-10-28T17:42:43 < dongie> ohhh
2013-10-28T17:42:46 < dongie> another announcement
2013-10-28T17:44:04 < zyp> hmm, I'm still waiting on the parallella
2013-10-28T17:44:08 < zyp> «may 2013»
2013-10-28T17:44:22 < Steffanx> At least not everyone is as impatient as dongie :)
2013-10-28T17:44:43 < dongie> whats delaying that one?
2013-10-28T17:44:47 < zyp> on the other hand, I still haven't even tried using the bladerf yet :p
2013-10-28T17:44:52  * emeb_mac is waiting for a zybo. not behind schedule yet tho
2013-10-28T17:44:55 < dongie> Update #41 Oct 13, 2013
2013-10-28T17:44:56 < dongie> Shipment Delays
2013-10-28T17:45:07 < dongie> Not sure where to start. The last couple of months have been a disaster and I am disappointed to report that we are still weeks away from being able to ship the final Parallella products. What went wrong? Well, pretty much everything.
2013-10-28T17:45:12 < dongie> LOL
2013-10-28T17:45:13 < Steffanx> but zybo is not a ks project is it emeb_mac?
2013-10-28T17:45:23 < emeb_mac> Steffanx: that's right.
2013-10-28T17:45:34 < emeb_mac> full-up commercial product due in Dec
2013-10-28T17:45:46 < emeb_mac> but still pre-ordered.
2013-10-28T17:46:47 < emeb_mac> ks should be renamed "introduction to reality for prospective hardware manufacturers"
2013-10-28T17:47:06 < emeb_mac> and their customers
2013-10-28T17:48:30 < zyp> :)
2013-10-28T17:48:51 < dongie> also, cocks.
2013-10-28T17:49:32 < emeb_mac> because honestly, what _isn't_ better without those.
2013-10-28T17:50:36 < BrainDamage> venereal diseases spreading stats
2013-10-28T17:52:41 < emeb_mac> sounds like that old joke about how religious fundamentalists who said aids was a punishment from god didn't realize that the implication of that was lesbians were god's chosen people.

2013-10-28T18:14:28 < gxti> while mu has been fucking around, flir released a real imager for something like $1000 that is hackable to high res and framerate
2013-10-28T18:14:47 < gxti> but it doesn't matter because mu is a scam anyway
2013-10-28T18:15:05 < dongie> gxti: they evne linked to flir shit in one of hteir updats.
2013-10-28T18:15:22 < dongie> Right now, our hardware design is complete, and we are working on our image processing software. This is without a doubt the most repetitive and tedious portion of the project. Constant changes to the imaging filter and Non-Uniformity Correction filter in order to produce a truly high quality image.

2013-10-28T20:31:28 < DanielHolth> "fascinating" how arm-none-eabi-gdb crashes when you use -g3
2013-10-28T20:33:03 < jpa-> doesn't do that for me
2013-10-28T20:33:11 < GargantuaSauce> what version?
2013-10-28T20:33:12 < jpa-> the .o files tend to be huge though :)
2013-10-28T20:34:09 < DanielHolth> 4-7-2013q3-0
2013-10-28T20:34:21 < fbs> gdb or gcc?
2013-10-28T20:34:26 < DanielHolth> gdb
2013-10-28T20:34:49 < fbs> oh like that
2013-10-28T20:34:50 < jpa-> that's not a gdb version AFAIK
2013-10-28T20:35:08 < fbs> nvm, i gdb crashes with gcc -g3, not with gdb -3g
2013-10-28T20:35:09 < jpa-> is that some codesourcery package?
2013-10-28T20:35:19 < DanielHolth> it's called gcc arm embedded
2013-10-28T20:35:26 < jpa-> launchpad?
2013-10-28T20:35:30 < DanielHolth> that one
2013-10-28T20:35:43 < jpa-> ok :)
2013-10-28T20:36:35 < jpa-> i haven't upgraded in a while, maybe that's why it works for me
2013-10-28T20:36:51 < jpa-> (with gdb 7.4.1)
2013-10-28T20:37:18 < fbs> seems to work here with 7.4.1.20130913-cvs
2013-10-28T20:37:24 < fbs> (launchpad)
2013-10-28T20:37:29 < gxti> what exactly is "gdb -g3" supposed to do?
2013-10-28T20:37:41 < fbs> gcc -g3
2013-10-28T20:37:46 < gxti> that's not what he said

2013-10-28T20:37:52 < DanielHolth> the trick is that it does not segfault on all code

2013-10-28T20:38:04 < fbs> gdb crashes when you use gcc -g3
2013-10-28T20:38:10 < gxti> ok.
2013-10-28T20:38:21 < DanielHolth> anyway I would have appreciated knowing that three weeks ago :-)
2013-10-28T20:38:31 < gxti> i've not had GAE crash, i did have TNT crash but a later build fixed it.
2013-10-28T20:38:53 < gxti> i use -ggdb3 though, which ought to be identical but i don't really know
2013-10-28T20:48:59 < GargantuaSauce> i use GNU gdb (Linaro GDB) 7.6-2013.05 and compile with -g3 and have never had a crash

2013-10-28T23:44:52 < Laurenceb__> i guess it would depend on the output driver
2013-10-28T23:44:56 < fbs> hmm lets try
2013-10-28T23:45:36 < madist> 10MHz ? probably track inductance on the pcb.

2013-10-28T23:53:11 < GargantuaSauce> madist i think you're off by an order of magnitude, i've done 40MHz serial through a breadboard!
2013-10-28T23:53:40 < Laurenceb__> nice work
2013-10-28T23:53:46 < Laurenceb__> that was fast Tectu
2013-10-28T23:53:53 < Tectu> Laurenceb__, thanks
2013-10-28T23:53:56 < madist> GargantuaSauce: 40MHz isn't supposed to work on a breadboard
2013-10-28T23:54:09 < GargantuaSauce> well excuse me for breaking the rules
2013-10-28T23:54:12 < Tectu> GargantuaSauce, please define "worked" here
2013-10-28T23:54:21 < GargantuaSauce> successful bidirectional communication?
2013-10-28T23:54:25 < Tectu> I bet the signal quality was horrible
2013-10-28T23:54:30 < Tectu> Laurenceb__, thanks.
2013-10-28T23:54:35 < GargantuaSauce> well i didn't notice any errors
2013-10-28T23:54:43 < Tectu> Laurenceb__, well, it's really just a small preparation release before the big 2.0 release within the following two months.
2013-10-28T23:54:57 < Laurenceb__> so does it support F429-discovery yet?
2013-10-28T23:55:05 < Laurenceb__> i forgoet the LCD controller on that board
2013-10-28T23:55:09 < Tectu> Laurenceb__, no - working on that next week.
2013-10-28T23:55:27 < Laurenceb__> ok cool
2013-10-28T23:55:28 < Tectu> Laurenceb__, Giovanni is currently working on the port (it's theoretically finished, just a few bugs).
2013-10-28T23:55:43 < Tectu> and writing the µGFX drivers shouldn't take more than a day or two
2013-10-28T23:56:20 < Tectu> Laurenceb__, btw, how is the storm thing going?
2013-10-28T23:56:39 < Laurenceb__> wut storm
2013-10-28T23:56:39 < emeb> w00t! loading data from SD card -> internal flash works on my F303
2013-10-28T23:56:44 < Laurenceb__> there is no storm now
2013-10-28T23:56:49 < Laurenceb__> emeb: nice
2013-10-28T23:56:56 < Laurenceb__> i need to get that running on F1
2013-10-28T23:57:00 < Tectu> Laurenceb__, I heard/saw some really crappy storm things in the UK yesterday or so
2013-10-28T23:57:03 < Laurenceb__> heh
2013-10-28T23:57:08 < Laurenceb__> only for the south coast
2013-10-28T23:57:11 < Tectu> ah
2013-10-28T23:57:13 < Laurenceb__> many miles away from me
2013-10-28T23:57:15 < Tectu> and you're living where?
2013-10-28T23:57:22 < Laurenceb__> it was like 5mph here - Derby
2013-10-28T23:57:22 < emeb> It's a lot simpler than I first thought - thanks to dongs & dekar for setting me straight on that.
2013-10-28T23:57:31 < Tectu> I see
2013-10-28T23:57:44 < Tectu> emeb, you should get both of them some thankyou-wine
2013-10-28T23:57:56 < Laurenceb__> troll-wine
2013-10-28T23:58:00 < emeb> I thought I'd have to shut off all ISRs & DMA, but it's OK to just program.
2013-10-28T23:58:07 < emeb> with everything still running
2013-10-28T23:58:19 < ds2> is there anything special about the F475's?
2013-10-28T23:58:28 < ds2> haven't they been out for years now?
2013-10-28T23:58:43 < Laurenceb__> emeb: sure not if you run from a partially reflashed area?
2013-10-28T23:58:55 < Laurenceb__> oh - you are running a bootloader?
2013-10-28T23:59:05 < emeb> Laurenceb__:  I'm not flashing code
2013-10-28T23:59:09 < Laurenceb__> i see
2013-10-28T23:59:16 < emeb> I'm only flashing a large data array (audio waveforms)
2013-10-28T23:59:40 < emeb> It's hilarious watching the output waveform as I flash it...
2013-10-28T23:59:54 < emeb> DMA is still running, accessing it as it gradually fills in.

2013-10-29T00:00:03 < Laurenceb__> i keep meaning to write a µSD firmware update thingy
2013-10-29T00:00:11 < Laurenceb__> but CE crap get in the way
2013-10-29T00:00:15 < emeb> Let me know if you ever get that going.

2013-10-29T13:23:41 < Laurenceb> trying to thread cables down flexible hose
2013-10-29T13:24:49 < Laurenceb> i wonder if there is a pro way to do this
2013-10-29T13:27:03 < Laurenceb> cuz atm i can thread about 2mm/minute
2013-10-29T13:27:15 < Laurenceb> and need 100m of cable/hose  :S
2013-10-29T13:27:54 < zyp> sounds like a pointless exercise
2013-10-29T13:28:19 < zyp> why do you need to add another sleeve to the cables?
2013-10-29T13:28:21 < Laurenceb> yeah theres got to be a pro way
2013-10-29T13:28:24 < Laurenceb> CE
2013-10-29T13:28:30 < Steffanx> why you don't buy cables that suite your need Laurenceb?

2013-10-29T13:28:38 < Laurenceb> they dont exist
2013-10-29T13:28:47 < Laurenceb> so thatd mean more rabbits
2013-10-29T13:28:52 < Laurenceb> rabbits are expensive

2013-10-30T08:00:12 < emeb_mac> so I've got an SD card and an LCD hanging off the same SPI bus. the SD card CS line is held high, but for some reason it seems to be interfering with communication to the LCD prior to running the initialization process.
2013-10-30T08:00:53 < emeb_mac> anyone seen this before?
2013-10-30T08:02:53 < dongs> how is that even possible
2013-10-30T08:03:31 < emeb_mac> my thoughts exactly
2013-10-30T08:04:05 < emeb_mac> if I pop the card out of the socket everything works fine
2013-10-30T08:04:47 < emeb_mac> if the card is in the socket and I initialize it (mount and open dir in Chan Fatfs) then everything is fine.
2013-10-30T08:05:15 < emeb_mac> but if card is in the socket and I don't read from it then eventually the LCD display locks up.
2013-10-30T08:15:58 < emeb_mac> oh look - chan fatfs has changed since last time I grabbed it.
2013-10-30T08:17:17 < dongs> OH
2013-10-30T08:17:20 < emeb_mac> I've got 0.09a and its up to 0.10 now

2013-10-30T08:17:47 < dongs> something in driver fucks wiht gpio?
2013-10-30T08:17:55 < emeb_mac> don't think so
2013-10-30T08:18:49 < emeb_mac> just wondering if perhaps the SD card needs to be forced into SPI mode to prevent unpredictable results.
2013-10-30T08:19:20 < emeb_mac> ie - maybe MMC mode doesn't use the CS line the same way.

2013-10-30T08:20:58 < emeb_mac> right
2013-10-30T08:21:16 < emeb_mac> so if there's a card present you need to initialize it OR ELSE!
2013-10-30T08:21:39 < emeb_mac> you can't just let it dangle there until you get around to it.

2013-10-30T16:21:43 < ouah> stm32l1 st lib has several functions to write in eeprom: typically byte,halfword,word
2013-10-30T16:21:54 < ouah> they are typically meant to be run from flash.
2013-10-30T16:22:10 < ouah> they also define a function to be run from sram
2013-10-30T16:22:48 < dongs> eeprom or flash?
2013-10-30T16:23:06 < dongs> i know L1 has real eeprom, why would you need to run eep functions from sram tho.
2013-10-30T16:24:05 < ouah> eeprom, stm32l1 has eeprom
2013-10-30T16:24:23 < dongs> right.
2013-10-30T16:24:29 < ouah> the function to be run from sram is doubleword
2013-10-30T16:24:30 < dongs> so i dont see why it would need ot be run from sram
2013-10-30T16:24:54 < ouah> dongs: me too
2013-10-30T16:25:28 < ouah> the one from sram it appears to be really *faster* than the one from flash
2013-10-30T16:26:15 < dongs> odd
2013-10-30T16:26:26 < ouah> but they only have the dword version from sram, and I failed to implement a same function to write a single byte (without doing a read-modify-write)
2013-10-30T16:26:46 < dongs> solution: store everytthing as dwords
2013-10-30T16:27:18 < ouah> dongs: if I have 2 bytes to write, I don't to write 8 bytes

2013-10-30T16:27:47 < ouah> I wonder if anybody succeeded to write a single byte to eeprom from sram
2013-10-30T16:28:10 < jpa-> ouah: if you want speed, you have to write in 32-bit sized words
2013-10-30T16:28:39 < jpa-> though i don't see why you couldn't write bytes using code running from SRAM, should be the same as code running from flash
2013-10-30T16:29:43 < jpa-> IIRC the stm32l1 stalls code execution from flash when you are writing eeprom, maybe that is why they do it from sram
2013-10-30T16:30:34 < fbs> Tectu : made ugfx right?
2013-10-30T16:31:00 < jpa-> yes

2013-10-30T16:31:45 < fbs> Tectu: 'Preassure measurement not implemented yet' is a typo i guess, on website/supported-systems
2013-10-30T16:32:32 < Tectu> fbs, fixed. Thank you very much!

2013-10-30T16:44:14 < Tectu> jpa-, thanks, the fitting one arrived a week ago :P
2013-10-30T16:44:17 < Tectu> was out of stock...
2013-10-30T16:45:31 < fbs> damn xtals, so many '2 smd' footprints
2013-10-30T16:45:39 < fbs> why cant they just use 1 or 2 sizes?
2013-10-30T16:45:52 < Tectu> many reasons for that.
2013-10-30T16:46:02 < fbs> not really
2013-10-30T16:46:14 < zyp> mostly one
2013-10-30T16:46:25 < zyp> lower freqs = physically larger
2013-10-30T16:46:41 < zyp> and you don't want a crystal that's larger than required
2013-10-30T16:46:51 < fbs> was talking case size
2013-10-30T16:46:54 < dongs> there are standard footprints.
2013-10-30T16:47:01 < dongs> use htem.
2013-10-30T16:47:02 < zyp> fbs, of course
2013-10-30T16:47:17 < zyp> lower freq crystals need a larger case
2013-10-30T16:47:30 < dongs> thats why i stopped using 8mhz xtals
2013-10-30T16:47:37 < dongs> 12mhz in 3225 = sex
2013-10-30T16:47:47 < fbs> im using abracon ones
2013-10-30T16:47:56 < fbs> the 32khz is actually smaller
2013-10-30T16:48:06 < dongs> abracon what
2013-10-30T16:48:08 < dongs> 8mhz?
2013-10-30T16:48:20 < dongs> smallest 8mhz you can get (reasonably) is 5x3.2

2013-10-30T21:17:47 < zyp> that's nice
2013-10-30T21:17:55 < zyp> do they ship to norway? :p

2013-10-30T21:20:03 < Steffanx> I asked someone from a local EE forum to order one for me :)
2013-10-30T21:20:13 < jpa-> one other reseller here charges 25% extra.. not sure if anyone uses them :)
2013-10-30T21:20:47 < zyp> looks like arrow has them in stock and sells to .nl

2013-10-30T21:23:51 < Steffanx> let me show you want i found on the web jpa-

2013-10-30T21:24:34 < Steffanx> oh, i don't read xkcd daily
2013-10-30T21:24:37 < jpa-> it came with my curtains
2013-10-30T21:26:21 < gxti> qyx_: why would that be a problem?
2013-10-30T21:26:59 < qyx_> gxti: i can't see the problem but also i have never seen anyone using them for this purpose

2013-10-30T21:47:54 < Steffanx> Not sure why he needs more transducers for that though :)
2013-10-30T21:48:09 < jpa-> Steffanx: no, i wanted to do sonar.. then some other guy wanted to do data transmission and that link is where i took some readings for him
2013-10-30T21:48:29 < jpa-> and for synthetic aperture sonar i would have needed more transducers
2013-10-30T21:49:01 < Steffanx> oh, not even data transmission. I was more interested in the data transmission. Thats how i found that photo.

2013-10-30T21:59:11 < qyx_> later i found one electret microphone with good response up to 60kHz
2013-10-30T21:59:25 < qyx_> but never had more time to try with standard speaker and electret mic
2013-10-30T21:59:27 < Steffanx> for a 40KHz transducer
2013-10-30T21:59:30 < jpa-> it would be great to be able to do chirps from e.g. 20kHz up to 200kHz

2013-10-31T01:14:07 < johntramp> hi,  I am using stlink to flash a stm32f4 discovery board. is there a way to use st-util to reset the board?
2013-10-31T01:14:57 < zyp> if you use gdb, then you can reset it by doing «run»
2013-10-31T01:15:41 < johntramp> hi zyp
2013-10-31T01:15:53 < johntramp> i am wanting to be able to put it into a bash script
2013-10-31T01:15:54 < zyp> hi
2013-10-31T01:16:15 < johntramp> would that require two processes?
2013-10-31T01:16:27 < mervaka> johntramp: you mean wipe it, or put the demo program back on?
2013-10-31T01:16:39 < johntramp> mervaka: just reset, same as pushing the reset button
2013-10-31T01:16:43 < mervaka> the former is easy, just connect to it and erase
2013-10-31T01:16:44 < mervaka> oh
2013-10-31T01:16:46 < mervaka> i see
2013-10-31T01:17:52  * mervaka takes a look
2013-10-31T01:18:00 < zyp> johntramp, well, as far as I know there is no standalone reset feature of the st-flash utility
2013-10-31T01:18:21 < zyp> but I might be wrong, I haven't used it for a year or two
2013-10-31T01:18:25 < johntramp> i have been doing it by st-flash write, but i know that isn't a good thing to be doing more than necessary
2013-10-31T01:18:32 < mervaka> yeah there is
2013-10-31T01:18:44 < mervaka> target -> MCU core
2013-10-31T01:18:51 < mervaka> lots of useful buttons there
2013-10-31T01:19:05 < zyp> mervaka, we're talking about the texane tool, I assume
2013-10-31T01:19:12 < zyp> no buttons anywhere ;)
2013-10-31T01:19:14 < mervaka> ST link utility?
2013-10-31T01:19:18 < johntramp> yes the command line app
2013-10-31T01:19:21 < mervaka> oh
2013-10-31T01:19:23 < johntramp> https://github.com/texane/stlink
2013-10-31T01:19:41 < mervaka> sorry, dunno then :p
2013-10-31T01:19:57 < mervaka> i just use uVision for everything :p
2013-10-31T01:20:00 < zyp> johntramp, when I develop I mostly do everything from gdb instead of from bash
2013-10-31T01:20:56 < zyp> the easiest solution for what you want would probably be using gdb -x to script gdb
2013-10-31T01:21:11 < zyp> and then just use run through gdb
2013-10-31T01:21:54 < mervaka> zyp: I'm going ahead with the LPC4357 for my project btw :o wish me luck!
2013-10-31T01:22:02 < johntramp> zyp: yeah ok thanks
2013-10-31T01:22:04 < zyp> otherwise you could whip up a script that talks gdb protocol directly to the st-util gdbserver, or whip up another cli utility to trigger a reset directly
2013-10-31T01:22:14 < zyp> or just add reset without flashing to st-flash
2013-10-31T01:22:30 < zyp> probably wouldn't be very hard
2013-10-31T01:22:38 < mervaka> audio mixer version 2!
2013-10-31T01:23:11 < zyp> oh, and then of course you could just ditch the texane stuff completely and switch to openocd, I hear openocd is pretty usable nowadays
2013-10-31T01:23:33 < zyp> but don't ask me for help with that, I'm not using that myself :)

2013-10-31T03:30:52 < emeb> OK - fixed that weirdness with the SD card. It's enough just to mount the card and open a directory regardless of if there's a card or not and whether or not I need a directory listing.
2013-10-31T03:31:31 < emeb> I'm using FF9a which doesn't actually mount the card when you do a "f_mount()" call, so the "f_opendir()" is needed.

2013-10-31T03:31:57 < emeb> FF10 has an option in f_mount() to force actually mounting though - may upgrade to that.

2013-10-31T11:25:24 < zyp> doesn't nrf24l01+ only support nrf proprietary protocol?
2013-10-31T11:26:59 < zyp> zigbee is built on top of 802.15.4 framing, so you need a transceiver that can do that

2013-10-31T11:45:14 < karlp> but yeah, 802.15.4 is different,
2013-10-31T11:46:46 < someone_r> ok so than i need another harware
2013-10-31T11:47:06 < dongs> haha
2013-10-31T11:47:14 < dongs> karlp: thats the guy who did lunix on AVR w/sdram right?
2013-10-31T11:48:02 < dongs> yep it is.
2013-10-31T11:48:05 < dongs> fucking nutcase.
2013-10-31T11:48:18 < karlp> it's good to have people like that in the world though :)
2013-10-31T11:48:33 < karlp> someone_r: what's your end goal?
2013-10-31T11:52:44 < someone_r> well...i would like idiot if i tell
2013-10-31T11:53:16 < someone_r> anyway, i wanted to check if i could reuse some nrf chip
2013-10-31T11:53:36 < someone_r> with the STM32
2013-10-31T11:54:16 < someone_r> and make them communicate to zigbee protocol...
2013-10-31T11:55:08 < someone_r> however it seems that i have to swithc completely... I was looking into the EM357 wich has MCU+RFzigBee
2013-10-31T11:55:55 < someone_r> and the MCU is still based on the ARM M3
2013-10-31T11:57:08 < karlp> are you looking at zigbee zigbee the closed commercial thing for any particular thing you want to integrate with?
2013-10-31T11:57:27 < karlp> or are you more just after some mesh radio stuff?
2013-10-31T11:57:49 < someone_r> i want to control multiple sensors
2013-10-31T11:57:59 < someone_r> on wireless
2013-10-31T11:58:10 < someone_r> so mesh radio stuff
2013-10-31T11:59:44 < someone_r> i have to do some reading for understanding better few topics...
2013-10-31T12:00:03 < someone_r> anyway... you guys are great...
2013-10-31T12:00:54 < someone_r> it is amazing that EVERYTHING that i ask... you have the answer...
2013-10-31T12:00:58 < someone_r> :D

2013-10-31T14:55:59 < jpa-> add "monitor reset halt" to the initialization
2013-10-31T14:56:11 < jpa-> maybe you'll want "load" also to verify the newest firmware is loaded
2013-10-31T14:56:29 < fbs> but what if i dont want a reset?
2013-10-31T14:57:09 < jpa-> "monitor halt" might work.. or just "continue" from gdb if you don't want to stop the running program either
2013-10-31T14:57:44 < fbs> hmm
2013-10-31T14:57:55 < fbs> debugging doesnt stop the iwdg?
2013-10-31T14:57:56 < jpa-> the 0x000000 in ?? comes because the program is still running AFAIK
2013-10-31T14:59:24 < jpa-> you can configure that in DBGMCU

2013-10-31T16:09:31 < dongs> I will need to get some certifications from the FCC & CE. Though the box isn't an emitter it does have a power supply built in, and because of that its falls into a less-stringent testing category.

2013-10-31T16:09:36 < dongs> haha

2013-10-31T21:04:17 < emeb1> Everyone have their Nexus 5 ordered?
2013-10-31T21:05:28 < Steffanx> why you think i need a nexus5? :)
2013-10-31T21:05:46 < qyx_> No.
2013-10-31T21:05:52 < emeb1> because it's the new hotness! upgrade or die!
2013-10-31T21:06:05 < zyp> I'm gonna stick with my nexus 4
2013-10-31T21:06:10 < zyp> it's nice enough
2013-10-31T21:06:17  * emeb1 still has an ancient flip-phone, so this is all sarcasm.
2013-10-31T21:06:43 < Steffanx> You think i have > $349 for a (stupid) phone emeb1?  :(
2013-10-31T21:07:10 < emeb1> beats me
2013-10-31T21:07:18 < emeb1> just trollin'
2013-10-31T21:08:24 < Steffanx> i do have a android phone.. but it can barely run it :(

2013-10-31T21:08:34 < zyp> $349 isn't that bad
2013-10-31T21:09:49 < emeb1> my main beef with smartphones is that I don't care to spend > $800/yr on a service plan
2013-10-31T21:10:07 < qyx_> my 7 years old k550i is still working, why should i need something hardly functional :S
2013-10-31T21:10:28 < zyp> emeb1, are they that expensive?
2013-10-31T21:11:04 < emeb1> zyp: here in the US the cell providers don't give any breaks on fees.
2013-10-31T21:11:50 < emeb1> in fact, if you try to do a low cost plan w/o data but you have a smartphone, the networks will detect that and tack on data.
2013-10-31T21:11:59 < zyp> emeb1, I'm on a plan at $50/month, includes way more calls, messages and data than I'm using

2013-10-31T21:12:21 -!- BrainDamage1 is now known as BrainDamage
2013-10-31T21:12:27 < emeb1> data plans here cost min $30/mo added onto a typical $30-$40/mo voice/text plan.
2013-10-31T21:12:58 < zyp> I could have went with a cheaper plan, but work covers $85/mo anyway, so I wouldn't save anything :p
2013-10-31T21:13:12 < emeb1> BYOD
2013-10-31T21:14:02 < BrainDamage> zyp: I'm gonna stick with my nexus 4 < OLD
2013-10-31T21:14:05 < zyp> the only usage I have outside the plan is when I go abroad
2013-10-31T21:14:06 < BrainDamage> ( someone had to )
2013-10-31T21:14:34 < zyp> and even that is pretty cheap nowadays
2013-10-31T21:15:16 < Steffanx> You know.. i don't have to be online when im not near my pc :)
2013-10-31T21:15:20 < qyx_> hm, i have 6e/mo flat gprs/edge access here
2013-10-31T21:15:32 < qyx_> + one minute for 0.13e
2013-10-31T21:15:34 < emeb1> I guess that $349 is for 16GB unlocked. That's unsubsidized and not much more than what I paid for my Samsung Galaxy Player a few years back.
2013-10-31T21:15:41 < Steffanx> im not important enough for that.
2013-10-31T21:15:59 < emeb1> would be hilarious to buy a smartphone and not use the phone aspect...
2013-10-31T21:16:15 < Steffanx> uhm, that's why people do nowadays.
2013-10-31T21:16:18 < zyp> Steffanx, I like being able to receive mail anywhere
2013-10-31T21:16:19 < Steffanx> oh, that was sarcasm
2013-10-31T21:16:32 < qyx_> you can even get ~2GB of hsdpa/hsupa for ~15e/mo here
2013-10-31T21:16:39 < Steffanx> To feel or to be important zyp? ;)
2013-10-31T21:17:15 < qyx_> or maybe more GB/less price, i don't watch all the offerings
2013-10-31T21:17:21 < qyx_> *lower
2013-10-31T21:17:40 < zyp> Steffanx, probably neither, I just like staying on top of things :p

2013-10-31T21:20:17 < emeb1> zyp: about how much data do you use/mo?
2013-10-31T21:21:12 < zyp> phone says I've been using 217 Mb during the last month
2013-10-31T21:21:56 < zyp> my plan includes 6 GB
2013-10-31T21:22:44 < zyp> but I think it was originally 1 GB when I signed up for it in december last year, then they increased it to 3 GB after a couple of months, and then doubled it to 6 GB only a few weeks ago

2013-10-31T21:24:22 < emeb1> Interesting.
2013-10-31T21:25:00 < emeb1> the 2GB plan from my provider is $55/mo. 500MB is $39/mo.
2013-10-31T21:25:26 < zyp> heh
2013-10-31T21:25:47 < zyp> before I got the current plan, I paid $17/mo for 500MB data only
2013-10-31T21:25:50 < emeb1> (both w/ unlimited voice/txt)
2013-10-31T21:26:02 < emeb1> No data-only plans on this provider.
2013-10-31T21:26:24 < emeb1> they have a 500MB + limited voice/txt for $29.
2013-10-31T21:27:15 < emeb1> and this outfit is on the low end of the cost spectrum.
2013-10-31T21:27:20 < zyp> oh, my $50 plan is actually after a discount
2013-10-31T21:27:35 < zyp> it's normally $68
2013-10-31T21:27:45 < emeb1> because they like you?
2013-10-31T21:28:18 < zyp> they had a campaign where you could sign up for a year with 25% off
2013-10-31T21:28:45 < zyp> so $50 would normally only give me 1.5 GB, not 6
2013-10-31T21:29:48 < zyp> hmm, no, that's not right, it still says 3 GB in the list for my current plan
2013-10-31T21:30:39 < zyp> I guess I'll have to look at it in december when my discount expires, can probably pick something cheaper then

2013-10-31T22:15:49 < karlp> america, beszt í heimi ;)
2013-10-31T22:16:48 < fbs> do i use DMA_Cmd or SPI_I2S_DMACmd to start a dma transfer?
2013-10-31T22:17:10 < karlp> you consult the most bestest stdperiphlib documentation.
2013-10-31T22:19:19 < fbs> i tried that
2013-10-31T22:22:26 < fbs> i think i need to enable the channel using spi_i2s_dma since the transfer complete event disables the channel
