2014-01-01T04:12:59 < emeb_mac> they were giving 'em away free a while back
2014-01-01T04:13:03 < dongs> rite

2014-01-01T04:14:23 < emeb_mac> hasn't done anything w/ it
2014-01-01T04:14:36 < dongs> for $10 more for free shipping
2014-01-01T04:16:36 < dongs> ugh
2014-01-01T04:16:41 < dongs> total¥7,495 free shipping: 7500
2014-01-01T04:17:37 < dongs> k solved
2014-01-01T04:17:42 < dongs> got some richtek dcdc and coils
2014-01-01T04:17:59 < dongs> 1028-1092-1-ND + 587-1998-1-ND
2014-01-01T04:22:10 < dongs> damn digikey export shit got gayed up
2014-01-01T04:22:20 < qyx_> The xCORE Tile expects each byte to be transferred with the least-significant bit
2014-01-01T04:22:24 < qyx_> first.
2014-01-01T04:22:24 < qyx_> lol
2014-01-01T04:22:41 < dongs> wats wrong wiht that
2014-01-01T04:23:01 < dongs> or is it that you can only get data into it serially
2014-01-01T04:23:05 < qyx_> you have to reverse that
2014-01-01T04:23:07 < dongs> via 1 bit bitbang
2014-01-01T04:23:18 < qyx_> if you use spi memory
2014-01-01T04:23:36 < emeb_mac> bass-ackwards
2014-01-01T04:24:56 < qyx_> btw it has standard jtag
2014-01-01T04:25:16 < qyx_> for sram & otp programming
2014-01-01T04:26:24 < dongs> who actually uses xmos in production
2014-01-01T04:27:33 < qyx_> seems ok to me for simple dsp
2014-01-01T04:27:43 < qyx_> but i have seen it for the first time 10min ago
2014-01-01T04:48:31 < upgrdman> i wonder how reliable cap-sense pads would be on a single-sided pcb

2014-01-01T05:59:19 < emeb_mac> laying out a board: https://dl.dropboxusercontent.com/u/17017364/bcc_sdr_front.jpg
2014-01-01T05:59:33 < dongs> lol geda
2014-01-01T05:59:47 < dongs> whats the bandwidth?
2014-01-01T06:00:08 < emeb_mac> 0.1 - 500MHz in. 40MSPS
2014-01-01T06:00:27 < dongs> whats 40msps in channel width
2014-01-01T06:00:28 < dongs> 40mhz?
2014-01-01T06:00:34 < dongs> or 20
2014-01-01T06:00:43 < gxti> mr nyquist would like a word with you
2014-01-01T06:00:47 < emeb_mac> actuall, it's 80MSPS, 35MHz max bw
2014-01-01T06:00:54 < dongs> thats why i said 20
2014-01-01T06:00:57 < dongs> ok
2014-01-01T06:05:53 < emeb_mac> mounts on top of this: http://ebrombaugh.studionebula.com/embedded/bcc_s6/index.html

2014-01-01T06:08:32 < dongs> you got beat to dickstarter tho
2014-01-01T06:08:51 < emeb_mac> by logi-bone?
2014-01-01T06:10:30 < gxti> anyone used any RF transceiver ICs that they particularly liked recently? looking for something for low power sensors etc

2014-01-01T06:13:17 < emeb_mac> besides the basic cc2xxx stuff?
2014-01-01T06:13:22 < emeb_mac> or nordic
2014-01-01T06:13:43 < gxti> nordic is up the right alley but i'd prefer something i can buy on digikey, probably microchip's offerings

2014-01-01T06:19:16 < dongs> your fucking mac crashed right as i pasted it
2014-01-01T06:20:01 < emeb_mac> not the mac - the new cable modem reconnects a couple times / day
2014-01-01T06:20:20 < qyx_> gxti: stm spirit1?
2014-01-01T06:21:20 < qyx_> i did layout for it with L151 but hever had enough time to try it
2014-01-01T06:21:40 < qyx_> working from 1.8V \o/
2014-01-01T06:21:42 < emeb_mac> dongs: what is that? some sort of DVB RX?
2014-01-01T06:21:47 < dongs> sdr tx
2014-01-01T06:21:58 < emeb_mac> interesting
2014-01-01T06:22:21 < dongs> 950-2150 mhz, 55MBd for symbol rate
2014-01-01T06:22:29 < dongs> its like $100 worth of parts there at most
2014-01-01T06:22:32 < dongs> costs 2.5k eur
2014-01-01T06:22:37 < emeb_mac> heh
2014-01-01T06:22:56 < emeb_mac> what's the part under the squishy purple heatspreader?
2014-01-01T06:22:58 < dongs> altera fpga w/pcie core for interface, then just dumping data to dac/tx
2014-01-01T06:23:06 < emeb_mac> no surprise
2014-01-01T06:23:06 < dongs> altera shit with pcie hard ip
2014-01-01T06:23:17 < emeb_mac> does it come w/ software?
2014-01-01T06:23:20 < dongs> yeah
2014-01-01T06:23:24 < dongs> software does all teh work
2014-01-01T06:23:28 < dongs> and just dumps IQ or wahtever over pci
2014-01-01T06:24:44 < dongs> http://www.dektec.com/Products/PCI/DTA-111/images/Block111.png
2014-01-01T06:24:47 < dongs> like thier typical block diagram
2014-01-01T06:25:39 < qyx_> nice shadows
2014-01-01T06:26:08 < emeb_mac> basic sdr
2014-01-01T06:27:04 < emeb_mac> but TX-only is boring
2014-01-01T06:27:15 < emeb_mac> that board I'm working on is TX/RX
2014-01-01T06:27:47 < qyx_> hm, do you use discrete vga or is it included on adc inputs?
2014-01-01T06:28:57 < emeb_mac> there's a PGA in the AD9865 RX path
2014-01-01T06:32:09 < qyx_> O_o interesting ic
2014-01-01T06:32:14 < qyx_> for its cost
2014-01-01T06:32:22 < emeb_mac> ya
2014-01-01T06:32:43 < qyx_> i cannot find min/max freq of freq synth
2014-01-01T06:32:45 < emeb_mac> $18 / qty1 @ DK, not bad considering what it does
2014-01-01T06:33:37 < qyx_> hm
2014-01-01T06:33:38 < qyx_> ok
2014-01-01T06:33:51 < dongs> wau
2014-01-01T06:33:51 < emeb_mac> ADF4351 - ~50MHz - 3GHz
2014-01-01T06:34:05 < emeb_mac> but we're only using it to 500MHz
2014-01-01T06:34:09 < dongs> so hax
2014-01-01T06:34:21 < emeb_mac> the mixer poops out beyond that
2014-01-01T06:34:26 < dongs> much rf
2014-01-01T06:34:35 < emeb_mac> mmmm yummy rf
2014-01-01T06:34:53 < dongs> LFCSP
2014-01-01T06:34:57 < qyx_> ah so it has IF inputs/outputs?
2014-01-01T06:34:58 < dongs> cool package bro
2014-01-01T06:35:19 < dongs> you can get it in  die form
2014-01-01T06:35:22 < dongs> i wonder who'd wnat that
2014-01-01T06:35:23 < emeb_mac> dongs: kickin' it old skool
2014-01-01T06:35:25 < dongs> cellphonefags?
2014-01-01T06:35:48 < qyx_> 80msps in cell phone?
2014-01-01T06:36:00 < dongs> who knows
2014-01-01T06:36:08 < qyx_> maybe some lte stuff
2014-01-01T06:36:14 < emeb_mac> qyx_:  switches to bypass mixer stages for direct in @ HF range
2014-01-01T06:38:11 < gxti> looks like BLE probably isn't worth it, a lot of effort learning the stack and the transceivers seem to always come with a builtin microcontroller you have to figure out
2014-01-01T06:38:24 < gxti> probably poorly documented and NDA-laden too
2014-01-01T06:38:45 < emeb_mac> lots of patents on that shit
2014-01-01T06:38:54 < emeb_mac> IP pools
2014-01-01T06:39:25 < qyx_> http://www.st.com/web/en/catalog/sense_power/FM1968/CL1976/SC1845
2014-01-01T06:39:27 < qyx_> this one
2014-01-01T06:39:28 < gxti> MRF49XA seems like a winner, cheap and dumb
2014-01-01T06:41:41 < gxti> qyx_: looks good too
2014-01-01T06:42:26 < emeb_mac> $2.50 @ DK - not badd

2014-01-01T07:04:37 < gxti> more features on the spirit1 but i think it's more worthwhile to me to have something easier to use right now
2014-01-01T07:28:02 < dongs> dongbee
2014-01-01T07:31:44 < dongs> ius that micorchip part available in dip
2014-01-01T07:31:59 < emeb_mac> lol
2014-01-01T07:45:24 < gxti> so yeah, gonna put together a little board with stm32L151 and mrf49xa so i can fail at two things at once

2014-01-01T16:40:08 < Robint91> Thorn, I don't call that KS campaign "not a scam"

2014-01-01T16:42:21 < Robint91> " LIES ALL
2014-01-01T16:42:24 < Robint91> ALL THOSE LIES
2014-01-01T16:43:16 < Robint91> Thorn, I guess around 30.000 € profit
2014-01-01T16:44:47 < jpa-> does making a profit make it a scam? :)
2014-01-01T16:49:08 < Laurenceb_> EEVblog is lame
2014-01-01T16:49:21 < Laurenceb_> guy is Australian
2014-01-01T16:49:24 < Laurenceb_> all you need to know
2014-01-01T16:49:26 < Robint91> jpa-, not exactly but it isn't the point of kickstarter
2014-01-01T16:49:46 < Robint91> Laurenceb_, I tend the believe EEVblog is becomming lame
2014-01-01T16:50:11 < Robint91> jpa-, he doesn't have that much start up cost
2014-01-01T16:50:13 < Laurenceb_> not as lame as #electronics tho
2014-01-01T16:50:16 < Laurenceb_> "<beaky> i lost my arduino earlier today"
2014-01-01T16:50:20 < Laurenceb_> the dramaz
2014-01-01T16:50:36 < Laurenceb_> "<beaky> im very upset"
2014-01-01T16:50:39 < Robint91> jpa-, not like the project of jeri ellesworth
2014-01-01T16:51:01 < Laurenceb_> jeri scamsworth
2014-01-01T16:51:37 < jpa-> Robint91: well, if he has a dayjob, why would he bother making any smaller orders?
2014-01-01T16:52:06 < Robint91> jpa-, the total BOM cost is like 15€ count 5€ for production and testing
2014-01-01T16:52:10 < Laurenceb_> "<intranick> Laurenceb_: what do you have against jeri ellsworth"
2014-01-01T16:52:14 < Robint91> so the total price is like 20€
2014-01-01T16:52:14 < Laurenceb_> un oh ragemode
2014-01-01T16:52:32 < jpa-> 5 EUR for production and testing? heh :)
2014-01-01T16:52:59 < Robint91> jpa-, it doesn't cost that much
2014-01-01T16:52:59 < jpa-> but yeah, still not particularly horrible profit
2014-01-01T16:53:17 < Robint91> jpa-, do you think that is too much or too less?
2014-01-01T16:54:00 < jpa-> Robint91: why would it be up to me to decide? if it is too expensive for you, don't buy (i wouldn't by it myself for that price, but someone would)
2014-01-01T16:54:34 < Robint91> jpa-, I mean the production cost
2014-01-01T16:54:40 < jpa-> at previous workplace they had some devices that cost 500 EUR to make and sell for 10kEUR :P   now that i could consider a scam ;)
2014-01-01T16:55:01 < jpa-> Robint91: depends totally on where it is made; IIRC it is made in australia, i don't know what it costs there
2014-01-01T16:55:14 < jpa-> the production cost here in finland would be more like 10-20 EUR for a small series
2014-01-01T16:55:34 < Robint91> jpa-, I don't would buy the uCurrent, I do already have a very good bench dmm
2014-01-01T16:56:59 < Robint91> jpa-, last time I paid for my VmarkerPen only 2€ for PCBA and I think 5€ for final assembly
2014-01-01T16:57:19 < jpa-> in china?
2014-01-01T16:57:46 < Robint91> jpa-, but that A) a fairly stuffed pcb B) made in belgium C) and the enclosure is PAIN IN DA *SS

2014-01-01T19:37:08 < qyx_> doesn't it have 4 pads actually but only 2 are shown for simplicity?
2014-01-01T19:37:28 < jpa-> now that would be silly
2014-01-01T19:37:28 < qyx_> both teerminal names are "feed/gnd"
2014-01-01T19:37:41 < qyx_> so i assume you can rotate the part either way
2014-01-01T19:37:42 < gxti> that's because it's symmetrical, one is feed and one is gnd
2014-01-01T19:37:57 < gxti> but it's not feed and gnd at the same time... which is what the layout suggests
2014-01-01T19:38:07 < emeb> maybe the pad that bridges between feed & gnd acts like a winding on an xfrmr to couple the signal into the chip antenna?
2014-01-01T19:38:17 < gxti> right, could just be RF magic
2014-01-01T19:38:20 < jpa-> gxti: my RF friend tells that some antennas really are like that, a short circuit at the input..
2014-01-01T19:38:30 < jpa-> don't ask me how it works
2014-01-01T19:38:35 < qyx_> lol
2014-01-01T19:39:10 < gxti> seems like having it short in the chip would be better, if nothing else for assembly
2014-01-01T19:39:34 < Steffanx> Just wait for R2COM he knows
2014-01-01T19:39:41 < gxti> unlikely

2014-01-01T19:42:45 < gxti> bit wacky ya
2014-01-01T19:43:50 < jpa-> also received three explanations when i asked on another channel how it works: "black magic" "microwaves" "mushrooms"
2014-01-01T19:44:09 < gxti> jpa-: thanks for confirming
2014-01-01T19:44:20 < gxti> i figured it was just rf magic but it's nice to find people who actually know wtf they're doing
2014-01-01T19:44:49 < qyx_> pulse finland, hm
2014-01-01T19:44:58 < qyx_> ask zyp, maybe the mushrooms are scandinavia related
2014-01-01T19:45:10 < gxti> nah, vodka
2014-01-01T19:45:29 < BrainDamage> jpa-: do you want a formal explanation of how the short works or something intuitive is better?
2014-01-01T19:45:41 < qyx_> oh, jpa- you are from .fi?
2014-01-01T19:46:02 < jpa-> qyx_: yeah; so clearly i'm an expert on pulse inc's antennas
2014-01-01T19:46:22 < jpa-> BrainDamage: i kind of understand how a short works on a transmission line, but i'm having hard time understanding how the antenna has anything to do with it
2014-01-01T19:46:37 < BrainDamage> the antenna is a load for the transmission line
2014-01-01T19:46:59 < BrainDamage> it sets one of the conditions of the differential equation that creates the oscillator that the line is
2014-01-01T19:47:21 < jpa-> but isn't the voltage at the short point = 0, so how can the antenna affect anything..
2014-01-01T19:47:29 < BrainDamage> the current isn't 0
2014-01-01T19:47:45 < jpa-> but the current doesn't even go through the antenna..
2014-01-01T19:48:01 < BrainDamage> huh?
2014-01-01T19:48:36 < BrainDamage> why do you say that?
2014-01-01T19:48:41 < jpa-> if i have an oscillating thingy (like a spring) and i short one point (connect it to some fixed structure) the wave just stops there.. it wouldn't go past it to the antenna that is connected only through that point
2014-01-01T19:49:06 -!- trepidaciousMBR [~trepidaci@217.155.204.2] has joined ##stm32
2014-01-01T19:50:21 < BrainDamage> but even in the vertial plane the wave has to propagate
2014-01-01T19:50:37 < BrainDamage> even if it's short, the distance is not 0
2014-01-01T19:50:42 < BrainDamage> so they are not equiponential
2014-01-01T19:50:55 < BrainDamage> in fact is propagates both horizontally and vertically
2014-01-01T19:51:04 < jpa-> yeah.. and the ground plane won't be an absolute zero either.. so the answer lies there?
2014-01-01T19:51:27 < mumptai> well, the obvious thing is that the pad is not electrically small
2014-01-01T19:51:31 < BrainDamage> you have to analyze both resonation conditions on the horizontal and vertical direction
2014-01-01T19:51:34 < BrainDamage> yep
2014-01-01T19:51:47 < jpa-> yeah.. i guess it makes sense
2014-01-01T19:52:01 < BrainDamage> and the vertical will actually be likely dimensioned so it turns the short load into an higher one
2014-01-01T19:52:06 < Robint91> mumptai, at 900MHz 2.75mm
2014-01-01T19:52:08 < Robint91> meh
2014-01-01T19:52:21 < jpa-> i wonder how critical the pad placements are for the antenna performance in that case
2014-01-01T19:53:03 < englishman> wow cool and 2dbi
2014-01-01T19:53:11 -!- sterna1 [~Adium@s83-191-130-156.cust.tele2.se] has quit [Quit: Leaving.]
2014-01-01T19:53:12 < englishman> did not know such things existed
2014-01-01T19:53:35 < gxti> i suspect its performance in practice, especially since i am a rf noob and have no fancy equipment, is going to be much worse than that
2014-01-01T19:53:47 < gxti> gonna be solder and pray
2014-01-01T19:54:19 < BrainDamage> do you have a spectrum analyzer?
2014-01-01T19:54:27 < gxti> loooool.
2014-01-01T19:54:40 < BrainDamage> ok, too fancy I see
2014-01-01T19:54:40 < jpa-> it's always fun to just place antennas with no means to verify even the basic impedance matching
2014-01-01T19:55:02 < emeb> gxti: send me a prototype - I've got an anyalyzer
2014-01-01T19:55:13 < emeb> analyzer even
2014-01-01T19:55:18 < qyx_> gxti: buy a dvb-t dongle & use gnuradio with fft
2014-01-01T19:55:28 < qyx_> it's $10
2014-01-01T19:55:36 < qyx_> better than nothing
2014-01-01T19:55:43 < emeb> or even sdr#
2014-01-01T19:55:45 < gxti> emeb: sure
2014-01-01T19:55:47 < emeb> easier to set up
2014-01-01T19:55:51 < BrainDamage> not a terrible idea, it'll be uncalibrated but you'll have a qualitative measurement of the output
2014-01-01T19:55:55 < jpa-> the method then is to "try some things and see if the power increases or decreases", right?
2014-01-01T19:56:00 < BrainDamage> yes
2014-01-01T19:56:06 < jpa-> yeah
2014-01-01T19:56:11 < BrainDamage> I'd put a length of stub in parallel to the antenna
2014-01-01T19:56:20 < BrainDamage> and then literally scratch until I see signal peak
2014-01-01T19:56:23 < jpa-> still better than my "add more aluminum foil and check when it fails"
2014-01-01T19:56:39 < emeb> like tuning the TV with a coat hanger.
2014-01-01T19:56:42 < mumptai> Robint91, that is indeed small, but propagation speed is dependant on the surrounding medium, which seems to ceramics and the antenna is also narrowband, which would be required for some resonant circuit inside. and both would be ways to squeeze a useable portion of a wave lenght between the two sides of the pad
2014-01-01T19:57:03 < BrainDamage> the pattern inside the antenna is not straight either
2014-01-01T19:57:26 < emeb> "assume fox network viewing positions"
2014-01-01T19:57:57 < Robint91> mumptai, those two pads are shorted with the connection of the antenna, it could by
2014-01-01T19:58:07 < Robint91> but what Er do they have to get to that lenght
2014-01-01T19:58:09 < BrainDamage> the whole thing looks to me like a directional coupler in antenna form
2014-01-01T19:58:38 < jpa-> transformers occur by accident at microwave freqs, and many things are quite lossless, so i guess a short circuit + resonance can work pretty well
2014-01-01T19:59:10 < BrainDamage> a directional coupler makes a fine impedance inverter ( transformer ) at microwave freqs
2014-01-01T19:59:26 < BrainDamage> altough it's not super broadband
2014-01-01T19:59:30 < BrainDamage> but it's fine in that case
2014-01-01T20:00:20 < emeb> if you look at data sheets for other ceramic antennas on that site, this one is nice because it needs no matchin.
2014-01-01T20:00:23 < mumptai> Robint91, well, i guess pulse electronics wont' tell us ;)
2014-01-01T20:00:34 < emeb> assume it works
2014-01-01T20:00:40 < Robint91> yeah
2014-01-01T20:01:06 < BrainDamage> you could actually calculate it
2014-01-01T20:01:17 < mumptai> and it won't be Er alone
2014-01-01T20:01:29 < BrainDamage> yep, mu_r matters too
2014-01-01T20:01:43 < BrainDamage> and the length of feedline is another impedance matching trace too :p
2014-01-01T20:02:26 < Robint91> BrainDamage, indeed, I guess that shunt component has something to do
2014-01-01T20:02:51 < BrainDamage> that shunt is more like fine tuning
2014-01-01T20:02:54 < emeb> BrainDamage: how can the length of the feedline be important - the datasheet doesn't spec any controls on it?
2014-01-01T20:03:25 < BrainDamage> emeb: it flattens the impedance over freq
2014-01-01T20:04:13 < BrainDamage> it presents a diff k ( impedance transformation coefficient ) over diff freq for compensating antenna's
2014-01-01T20:05:10 < BrainDamage> be glad at least it's a TEM transmission line :P
2014-01-01T20:05:32 < BrainDamage> having propagation coefficient being function of the freq isn't fun ...
2014-01-01T20:06:01 < emeb> but since they don't spec the length in the datasheet, that's an uncontrolled parameter. I guess this means "only experienced customers allowed"
2014-01-01T20:07:18 < emeb> ie - your mileage _will_ vary because we're not telling you everything about the circuit...
2014-01-01T20:07:27 < BrainDamage> well, it's more of a secondary tuning, but yes
2014-01-01T20:08:24 < mumptai> well, you either make a blind try and possibly get lucky, or you need some decent equipment anyway
2014-01-01T20:08:52 < gxti> i think no matter how much you understand about it you still need to tweak crap
2014-01-01T20:09:13 < mumptai> not unlikely
2014-01-01T20:09:17 < emeb> or else you're enough of an antenna's guru that you probably could have built it yourself with a dead fly and a paperclip.
2014-01-01T20:09:37 < mumptai> or you at least want to confirm a stable performance
2014-01-01T20:09:56 < BrainDamage> well, using a simulator at microwave is pretty much nonoptional
2014-01-01T20:09:59  * emeb knows guys like that
2014-01-01T20:10:24 < BrainDamage> all models that you do todesign are correct only at first order or for small deviations from resonance freq
2014-01-01T20:10:28 < emeb> which is why they give you the smith chart
2014-01-01T20:10:29 < mumptai> simulator won't help without an antenna modell
2014-01-01T20:11:20 < emeb> but since they only nail down three frequencies it's just this side of useless...
2014-01-01T20:12:22 < BrainDamage> actually simulator can help with an antenna model provided you know the paramters like geometry, etc
2014-01-01T20:12:27 < mumptai> it won't help much, as there is no geometric data to support the layouter's job
2014-01-01T20:12:27 < BrainDamage> there's different types of sims
2014-01-01T20:12:34 < BrainDamage> that yes
2014-01-01T20:14:42 < mumptai> there actually is a third option, convince there field application engineer to support you ;)
2014-01-01T20:15:19 < BrainDamage> or connect an VNA to the actual antenna

2014-01-01T20:18:49 < emeb> looking at the ds - there's a pretty "fun" balun needed to get from their differential output to 50ohm...

2014-01-01T20:20:31 < gxti> there are some just for the nordic chips but i doubt there are for the microchip one i'm using
2014-01-01T20:20:48 < gxti> and even if they are they are less obtainable than plain old 0402 rf passives
2014-01-01T20:22:23 < gxti> so which of these would be better? http://partiallystapled.com/~gxti/circuits/2014/01/01-chipant1.png http://partiallystapled.com/~gxti/circuits/2014/01/01-chipant2.png
2014-01-01T20:22:42 < gxti> (ignore lack of via stitching or appropriate fill pullback)

2014-01-01T20:42:32 < Robint91> gxti, you can easy get 50 Ohm on normal FR4 material

2014-01-01T20:57:33 < Robint91> wut
2014-01-01T20:57:42 < Robint91> this becomes nice
2014-01-01T20:58:30 < zyp> with optional usb
2014-01-01T20:58:50 < zyp> hmm
2014-01-01T20:59:45 < zyp> maybe that one is usable for a cortex-m + fpga project I've been considering, using the xmos cores instead of the fpga for handling io
2014-01-01T21:00:42 < emeb> ya - spotted those ARM + XMOS chips while browsing the website yesterday
2014-01-01T21:00:53  * emeb still likes FPGA better...
2014-01-01T21:02:43 < gxti> heh, CPW is still impractically wide although half as wide as microstrip
2014-01-01T21:03:03 < gxti> i don't think it will matter much as it's only 6mm long
2014-01-01T21:03:38 < mumptai> but 50ohm microstrips on 1.5mm FR-4 .. that is going to be huge
2014-01-01T21:03:44 < zyp> I just need something that can handle reception and transmission of packets on a parallel bus so I can process them on a cortex-m
2014-01-01T21:03:59 < Robint91> gxti, narrow the spacing between plane and the rf trace
2014-01-01T21:04:02 < gxti> right, microstrip is about 110mil, CPW is about 45
2014-01-01T21:04:09 < gxti> that's with minimum clearance
2014-01-01T21:04:32 < mumptai> only 110mil?
2014-01-01T21:06:20 < emeb> ya - if you want good 50 ohm, go 4-layer. 12-mil for the thickness between L1/L2
2014-01-01T21:06:22 < gxti> plus for CPW to work presumably there has to be a large amount of ground on each side which i don't presently have room for
2014-01-01T21:06:46 < gxti> but again, it's only 6mm long. i don't think matching perfectly is going to yield much benefit.
2014-01-01T21:07:48 < gxti> and i don't really care if this is not perfectly efficient, it just needs to work
2014-01-01T21:08:19 < zyp> the xmos on the startkit is a 19x19 bga
2014-01-01T21:08:28 < zyp> and the board is 2-layer
2014-01-01T21:08:36 < mumptai> (the 50W strip itself would be like 2.6 mm, and you still need some clearance to the sides)
2014-01-01T21:08:49 < emeb> whoa!
2014-01-01T21:09:14 < zyp> the chip only has io on the outer two rings, the middle 9x9 pads are almost all grounds
2014-01-01T21:09:26 < emeb> interesting
2014-01-01T21:10:01 < emeb> I see they also have a lot of LQFP pkgs too - but they all seem to have exposed pad.
2014-01-01T21:11:28 < zyp> the one on the startkit is a dual-core device that they've rebranded into «A8DEV», which in other words means that they've reserved one core for running a programmer/debugger, that programs the other core
2014-01-01T21:11:39 < zyp> that's a fun approach

2014-01-01T21:15:13 < zyp> looks like digikey only stocks the L-series
2014-01-01T21:16:10 < Robint91> I wonder how the arm and the XMOS are connected
2014-01-01T21:16:58 < zyp> looks like everything but the L and a couple of the U-series devices aren't available yet
2014-01-01T21:17:05 < zyp> «contact xmos sales»
2014-01-01T21:19:09 < zyp> Robint91, hard to say, there's not a datasheet available yet
2014-01-01T21:20:16 < Robint91> on those xmos is each core 500mips or is that shared
2014-01-01T21:20:33 -!- sterna [~Adium@s83-191-130-156.cust.tele2.se] has joined ##stm32
2014-01-01T21:20:46 < fbs> shared id guess
2014-01-01T21:20:58 < zyp> one xmos core is 500mips and can handle up to 8 threads, but no thread can run at more than 1/4 duty due to pipelining
2014-01-01T21:21:08 < zyp> so you have max 125 mips per thread
2014-01-01T21:21:35 < Robint91> logical core = thread
2014-01-01T21:21:38 < fbs> oh damn
2014-01-01T21:21:39 < zyp> yes
2014-01-01T21:21:59 < gxti> seems pretty boring then
2014-01-01T21:22:00 < zyp> logical core = set of core register that holds one thread's state
2014-01-01T21:22:07 < fbs> thats a fancy ledblinker
2014-01-01T21:23:18 < Laurenceb_> whats the M3 clock speed?
2014-01-01T21:23:33 < zyp> I also wonder about that
2014-01-01T21:23:40 < zyp> there's no mention of it in the databrief
2014-01-01T21:23:43 < Laurenceb_> yeah i can't see it
2014-01-01T21:23:48 < zyp> and no other documentation available yet
2014-01-01T21:25:12 < zyp> gxti, maybe not so boring if what you do can utilize multiple threads
2014-01-01T21:26:10 < zyp> especially not if you consider that they have chips with multiple cores, and interconnects that allow you to hook together multiple chips
2014-01-01T21:28:50 < emeb> IIRC these guys are refugees from the old Inmos Transputer design team. Lots of similarities to that.
2014-01-01T21:28:59 < zyp> yes
2014-01-01T21:29:16 < emeb> esp - the chip-to-chip comm channels.
2014-01-01T21:29:37 < emeb> which IIRC also sent its serial data lsbit first. :P
2014-01-01T21:30:16 < zyp> I remember reading an article about one of the transputer guys once, thinking it sounded similar to xmos, and then they mentioned xmos in the end of the article :p
2014-01-01T21:41:18 < qyx_> i also lolled on 1lsb first when i saw that yesterday
2014-01-01T21:43:03 < zyp> does lsb first matter?
2014-01-01T21:47:10 < qyx_> they mentioned that you even have to save your program in spi memory with bits exchanged
2014-01-01T21:47:17 < qyx_> because it loads 1lsb first on boot
2014-01-01T21:48:12 < zyp> only applies if you're booting from external memory

2014-01-02T01:39:49 < zyp> yeah, that's what I've heard

2014-01-02T01:47:56 < zyp> I'm not yet sure how large the packets I want to receive are, or how flow control works, if there is any, but I imagine I want a packet buffer that can be accessed both by the io module and the microcontroller
2014-01-02T01:48:42 < zyp> that'll be a hassle if I'm going mcu+fpga, since the built in block rams probably won't be large enough, and the fpga can't access mcu memory
2014-01-02T01:49:12 < dongs> fsmc?

2014-01-02T01:51:04 < zyp> smartfusion would be kinda nice, since it provides a master port on the memory interconnect for the fpga logic
2014-01-02T01:52:02 < GargantuaSauce> are dual-port SRAMs reasonably affordable?
2014-01-02T01:52:59 < zyp> don't need one, I could just arbitrate it in the fpga
2014-01-02T01:52:59 < GargantuaSauce> oh yeah that makes more sense
2014-01-02T01:53:07 < mumptai> zyp, maybe you want to have a look ate the loa project over at github, its a stm32f4 + spartan fpga board
2014-01-02T01:53:40 < mumptai> we designed it to control robots, but it is not specifically tied to that domain
2014-01-02T01:56:35 < mumptai> https://github.com/dergraaf/loa
2014-01-02T01:56:42 < zyp> already reading
2014-01-02T01:57:37 < zyp> I love how you designed it with two jtag connectors which both deviates from the standard one for the device, and which are different from each other :p
2014-01-02T01:58:37 < mumptai> its more like some of us burned their fingers with incompatible jtag chains before
2014-01-02T01:59:23 < zyp> sure, I'm not telling you to hook them together, I just don't understand the love for nonstandard pinouts :p
2014-01-02T02:01:59 < mumptai> but what connector do you want? the 20 pin 100mil header, or the 10 pin at 50 mil?
2014-01-02T02:02:22 < zyp> the latter, it's the new standard
2014-01-02T02:03:40 < zyp> anyway, that's not relevant
2014-01-02T02:03:56 < zyp> is the only interconnect between the mcu and fpga spi?
2014-01-02T02:04:02 < mumptai> connectors weren't really availiable at that time, and (this is a application specific one) the 100mil type one stand the abuse in mobile robots a bit better
2014-01-02T02:04:04 < zyp> that's way too slow
2014-01-02T02:04:59 < mumptai> the never board version supports the fsmc

2014-01-02T02:44:00 < zyp> I'm not sure what IO level I'm going to be dealing with yet
2014-01-02T02:44:18 < emeb> zyp: Spartan 3 is 5V tolerant if you put a 10k resistor in series. :)
2014-01-02T02:44:19 < mumptai> do i want to try it for projects of similar size?
2014-01-02T02:44:33 < zyp> emeb, that's what I might do
2014-01-02T02:44:41 < dongs>  < mumptai> ohh, a geda user
2014-01-02T02:44:44 < emeb> mumptai: I've done a lot of mid-size stuff with gEDA/PCB
2014-01-02T02:44:44 < dongs> thats an insult

2014-01-02T02:46:17 < dongs> @ both
2014-01-02T02:46:38 < gxti> but it barely counts as a candidate to begin with
2014-01-02T02:46:42  * emeb uses diptrace too
2014-01-02T02:48:48 < upgrdman> emeb: with geda pcb, do you know if its possible to thermal a SMD pad to a ground fill?
2014-01-02T02:50:13 < dongs> you'd fucking hope so
2014-01-02T02:50:14 < dongs> thats like basic thing
2014-01-02T02:50:20 < dongs> ???
2014-01-02T02:51:02 < gxti> it's been so long since i used it, thankfully
2014-01-02T02:51:17 < gxti> i remember it can definitely thermal to vias so it had better work for pads oto
2014-01-02T02:55:15 < upgrdman> i've been thermal'ing manually because afaik geda pcb will onto thermal PTH holes, not pads.
2014-01-02T02:55:25 < upgrdman> which, if correct, is rtaded
2014-01-02T02:55:29 < upgrdman> rtarded even

2014-01-02T03:17:08 < emeb> it is annoying how the tool automatically makes pads clear fills
2014-01-02T03:17:45 < emeb> so I usually have to use fat lines without the "clears fills" set.

2014-01-02T05:54:31 < gxti> kinda weird that L1 does not have a separate VBAT pin, simple enough if my project is only battery powered but if i just want a battery backed RTC i have to add diodes and crap while F1 makes it easy
2014-01-02T05:55:12 < gxti> either that or arduino it up with a i2c rtc
2014-01-02T05:55:31 < qyx_> "arduino it up"
2014-01-02T05:59:13 < gxti> and if i use f1 then i lose the onboard eeprom and have to add that instead. looks like there's i2c in my future either way.
2014-01-02T06:01:31 < qyx_> if you have rtc sram backupped, why not use it?
2014-01-02T06:02:44 < qyx_> if you can accept losing data when exchanging the battery
2014-01-02T06:04:00 < zyp> doesn't L1 have vbat?
2014-01-02T06:04:30 < gxti> L151 doesn't, haven't looked at others. of course it consumes so little power in standby mode it works fine on battery, but if i want dual power sources i have to deal with diodes or switches or whatever myself

2014-01-02T06:08:12 < qyx_> does it really have just 16bit fifo or did i miss something?
2014-01-02T06:08:29 < qyx_> and is the minimum fsk deviation 15kHz?

2014-01-02T15:19:16 < Robint91> dongs, something like a nice LG panel
2014-01-02T15:19:16 < dongs> there's some legit places
2014-01-02T15:20:08 < dongs> that sell them i guess.
2014-01-02T15:20:08 < dongs> chinks.
2014-01-02T15:20:08 < dongs> i buy most of my legitshit from http://www.aroseks.com/
2014-01-02T15:20:08 < Robint91> dongs, panelook?
2014-01-02T15:20:08 < dongs> panelook is only useful for datasheets
2014-01-02T15:20:11 < dongs> im not paying 800bux to be their vip faggot to be able to buy shit there
2014-01-02T15:21:02 < dongs> i just shat them up on skype and get quotes for stuff.
2014-01-02T15:23:54 < Robint91> dongs, and say if I want a panel with touchscreen
2014-01-02T15:23:54 < dongs> then you're gay, cuz touchscreens suck
2014-01-02T15:23:54 < dongs> they do sell some assemblies
2014-01-02T15:23:54 < dongs> like for fagbook pro
2014-01-02T15:23:54 < dongs> since that shit comes as a single unit
2014-01-02T15:23:54 < dongs> i never cared about touchscreen so I duno where you'
2014-01-02T15:23:54 < dongs> d get them
2014-01-02T15:27:00 < Robint91> dongs, how is porduct lifetime handles, lets say I pick now a screen would I have that same screen within 6 months?
2014-01-02T15:27:00 < Robint91> or is that you continualy need to update?
2014-01-02T15:27:00 < dongs> well, if you pick something that others use a lot
2014-01-02T15:27:10 < dongs> then no i guess?
2014-01-02T15:27:10 < dongs> i mean, you can't go wrong wiht say jewpad screen
2014-01-02T15:27:10 < dongs> that shit will never be out of stock :)
2014-01-02T15:27:51 < jpa-> better prepare for the eventuality that you need to switch model some time
2014-01-02T15:27:51 < Robint91> dongs, need something in the range of 12.1 inch
2014-01-02T15:27:51 < dongs> you can get product roadmaps off panelook
2014-01-02T15:29:02 < dongs> Robint91: auoptronics has a lot of screens with different models/sizes but pin compatible interface connector
2014-01-02T15:29:02 < dongs> so.. you can check which ones are in the range you want and then you can substitute similar/next model once shit expires etc.
2014-01-02T15:29:10 < dongs> i duno about lvds im only speaking for eDP
2014-01-02T15:31:04 < Robint91> okay

2014-01-02T15:40:08 < Robint91> absolute
2014-01-02T15:40:16 < dongs> is it?
2014-01-02T15:40:19 < Robint91> I think so
2014-01-02T15:40:26 < Robint91>   /* Move to end of the file to append data */
2014-01-02T15:40:32 < Robint91>     res = f_lseek(fp, f_size(fp));
2014-01-02T15:41:07 < jpa-> yeah, only absolute AFAIK
2014-01-02T15:41:07 < Robint91> You can't do this if it relative
2014-01-02T15:41:07 < Robint91> when you did this before

2014-01-02T15:47:41 < jpa-> Laurenceb: when file grows larger, you need to allocate new sectors; by default you only allocate a few new sectors, so soon you need to reallocate again.. but if you know you are going to write 100 MB of data, better allocate all at once

2014-01-02T15:48:08 < Laurenceb> right
2014-01-02T15:48:12 < Laurenceb> so allocation involves writing to the disk?

2014-01-02T15:48:27 < Laurenceb> ah ok

2014-01-03T00:00:57 < HD_Mouse> i have the right number of bytes configured, but I only want to send this particular number of bytes if the correct command code is received
2014-01-03T00:02:23 < HD_Mouse> when the wrong command byte is received (in the spi_rx interrupt handler now) i try to turn of DMA, but it doesn't turn off until the next transaction, so the DMA fires anyway and the information is sent from the wrong byte, is there any way to make it turn off immediately?

2014-01-03T00:25:01 < HD_Mouse> scrts: i'm sorry i'm confused, which DMA interrupt are you talking about?
2014-01-03T00:25:46 < HD_Mouse> the only DMA interrupts i have for this MCU are Half Transfer complete, Transfer Complete, and Transfer Error
2014-01-03T00:28:19 < HD_Mouse> none of those strike as appropriate places for disabling DMA or telling the memory pointer to stop incrementing

2014-01-03T04:38:26 < Rickta59> so i keep waiting for someone to do an stm32 arduino .. why hasn't it happened?
2014-01-03T04:39:12 < Rickta59> the software, not the form factor

2014-01-03T04:41:26 < emeb> ummm... isn't that maple board an STM32-based arduino thing?
2014-01-03T04:41:47 < Rickta59> yeah i just looked at it ..
2014-01-03T04:41:52 < Rickta59> not really being maintained
2014-01-03T04:42:03 < Rickta59> and the whole thing is a hack
2014-01-03T04:42:09 < gxti> then probably the answer to your question is "because it's not interesting"
2014-01-03T04:42:46 < gxti> there are already eleventy million arduino variants, why would one more with stm32 be any better?
2014-01-03T04:42:58 < Rickta59> better peripherals
2014-01-03T04:43:01 < Rickta59> more flash
2014-01-03T04:43:01 < emeb> because ARM
2014-01-03T04:43:02 < Rickta59> more memory
2014-01-03T04:43:11 < gxti> there are multiple cortex-m arduinos already too
2014-01-03T04:43:13 < Rickta59> and low cost
2014-01-03T04:43:36 < Rickta59> yeah but as with anything arduino they are overpriced
2014-01-03T04:43:46 < emeb> but if you've gone to the trouble of doing an STM32 board, why not go the extra few steps and learn to program it for reals
2014-01-03T04:43:48 < gxti> and you can't compete on cost with a stm32 discovery board anyway
2014-01-03T04:43:59 < Rickta59> because most people are lazy
2014-01-03T04:44:13 < emeb> and lazy people just used arduino
2014-01-03T04:44:14 < Rickta59> yeah i'm talking about why hasn't anyone done a port for the stm32f4
2014-01-03T04:44:18 < gxti> so basically your target audience is people who want to use a mediocre IDE to program a board, but are smart enough to pick something other than atmega
2014-01-03T04:44:18 < Rickta59> discovery
2014-01-03T04:44:31 < gxti> effectively nil
2014-01-03T04:44:43 < Rickta59> it is more than the ide .. the ide sucks
2014-01-03T04:44:56 < emeb> then what - the libraries?

2014-01-03T04:46:14 < Rickta59> for the arm

2014-01-03T04:46:44 < gxti> well you're seriously confused
2014-01-03T04:46:53 < Rickta59> i've thought about usign the libopencm3 thing as a base for the core
2014-01-03T04:47:04 < gxti> if you want it then make it happen and see if anyone shows up
2014-01-03T04:47:07 < Rickta59> but i didn't want to waste my time as i thought someone else woudl do it
2014-01-03T04:47:49 < gxti> anyway time to lift some ICs
2014-01-03T04:56:39 < dongs> 11:43 < Rickta59> better peripherals
2014-01-03T04:56:40 < dongs> 11:43 < Rickta59> more flash
2014-01-03T04:56:43 < dongs> who cares about better peripherals
2014-01-03T04:56:48 < dongs> if tarduino just bitbangs everything
2014-01-03T04:57:07 < dongs> Rickta59: http://www.kickstarter.com/projects/1883701526/matchboxarm
2014-01-03T04:58:18 < gxti> lifted all the isolators, now the USB side is good but the target side is still short even though all that's left is two FETs, a LED, and some passives
2014-01-03T04:58:22 < gxti> time for some high-current debugging
2014-01-03T04:59:43 < Rickta59> what? no DAC dongs ?
2014-01-03T05:01:16 < dongs> i was joking. its trash.
2014-01-03T05:01:54 < dongs> i've been selling same shit for $10 for over a yera and i sold just over 50 of htem
2014-01-03T05:02:14 < Rickta59> is that because there is no software for it?
2014-01-03T05:02:33 < dongs> thats because anyone who wants to do arm development can either 1) make their own hardware 2) buysd -discovery
2014-01-03T05:02:33 < gxti> didn't even get a chance to probe, i touched the power to it and heard a faint pop and now there's no short

2014-01-03T21:09:05 < GargantuaSauce> yeah there is definitely some ringing and that will help
2014-01-03T21:09:08 < gxti> finally, you can get mosfet driver ICs for cheap :P

2014-01-03T21:24:51 < GargantuaSauce> oops that was wrong, Vgs after the ringing settles in a microsecond or so is about 4V which indeed is a little low...guess i'll need another voltage supply for the gate drivers
2014-01-03T21:27:50 < fbs> you should be able to power them from your 24V supply
2014-01-03T21:28:28 < GargantuaSauce> maximum Vgs on the fets is 20V
2014-01-03T21:30:26 < GargantuaSauce> can probably get away with a shunt regulator anyway

2014-01-03T22:04:57 < GargantuaSauce> yeah it's just a totem pole
2014-01-03T22:08:32 < Lux> interesting circuit btw. I bet the driver ICs are pretty similar to that design

2014-01-03T22:11:33 < GargantuaSauce> i think the ICs usually have proper charge pumps for the high side driving
2014-01-03T22:12:09 < Lux> depends, the hip2101 also has a cap like the schematic you posted

2014-01-03T23:33:56 < zippe> Anyone have a favorite tinted material for diffusing RGB LEDs?
2014-01-03T23:34:18 < jpa-> why tinted?
2014-01-03T23:35:05 < gnomad> to eliminate the point source, i suppose...
2014-01-03T23:35:39 < jpa-> hmm, i thought "tinted" was "colored", as in not just white/gray diffused
2014-01-03T23:40:55 < zippe> Tinted to reduce the visibility of the non-LED crap that's also behind the panel
2014-01-03T23:41:37 < jpa-> so dark gray or something?
2014-01-03T23:41:44 < zippe> Something like that.
2014-01-03T23:41:53 < jpa-> go to your plastic shop and pick whatever looks nice :P
2014-01-03T23:42:07 < zippe> The easy answer is smoked acrylic, but I was wondering if anyone had found something nicer
2014-01-03T23:42:34 < zippe> A matte finish would be good, for example
2014-01-03T23:42:57 < jpa-> if you really want to get rid of pointiness, a good solution is to have a thin white "milky" acrylic inside, a small gap and then the smoke gray acrylic
2014-01-03T23:44:07 < zippe> Right; my current plan is http://www.tapplastics.com/product/plastics/plastic_sheets_rolls/led_ligh_panel/598

2014-01-04T07:04:11 < dongs> no shit?
2014-01-04T07:04:15 < dongs> did you already sell them all?
2014-01-04T07:04:29 < zyp> posted six yesterday, sold another four today

2014-01-04T07:04:53 < zyp> and then I've been talking to a guy that want 20 or so
2014-01-04T07:04:56 < zyp> so yeah
2014-01-04T07:04:57 < dongs> dont make any changes ( or none that change stencil ) and assembly is a lot cheaper
2014-01-04T07:05:15 < zyp> that's what I figure
2014-01-04T07:06:57 < zyp> there aren't really much changes I'd like to make either way, and I'm too lazy to be dicking around with schematics and maintaining another firmware variant
2014-01-04T07:07:09 < dongs> heh right
2014-01-04T07:07:26 < zyp> so I figure I'll just make another batch exactly the same
2014-01-04T07:07:37 < zyp> mind getting me a quote for that?
2014-01-04T07:07:39 < dongs> sounds good to me
2014-01-04T07:07:40 < dongs> sure

2014-01-04T07:07:44 < dongs> 100?
2014-01-04T07:08:24 < zyp> I asked for 100, they said 112 was standard panel size or something, so I bought parts for 112
2014-01-04T07:08:30 < dongs> oh right
2014-01-04T07:08:44 < zyp> and then I got 105 assembled, 20 leftover boards and a bunch of leftover parts :p
2014-01-04T07:08:48 < dongs> how many did you get?
2014-01-04T07:08:48 < dongs> ah
2014-01-04T07:08:59 < dongs> oh right, 112 was full fr4 panel
2014-01-04T07:09:08 < zyp> or rather, 106 assembled, the last was without connectors like I asked for
2014-01-04T07:09:27 < zyp> anyway, if 112 is full panel, then I'll do 112
2014-01-04T07:09:28 < dongs> i handled all the parts except sockets that came form digikey right?
2014-01-04T07:09:45 < zyp> whatever is a nice round number for them works for me
2014-01-04T07:09:47 < dongs> since china couldnt clone those
2014-01-04T07:09:51 < zyp> yeah
2014-01-04T07:10:01 < dongs> ok, ill get you something by monday probly
2014-01-04T07:10:22 < zyp> no hurry
2014-01-04T07:10:26 < dongs> yep;
2014-01-04T07:10:53 < zyp> unless there's a risk of hitting chinese new years, probably a good idea to get parts before that :p
2014-01-04T07:11:14 < dongs> parts just takes a day
2014-01-04T07:11:16 < dongs> no problem
2014-01-04T07:11:24 < dongs> i can just have them pull old list and reorder same shit
2014-01-04T07:12:00 < dongs> know any board to b oard right angle socket
2014-01-04T07:12:03 < dongs> thats cheap that you used before?
2014-01-04T07:12:05 < dongs> 6 pins
2014-01-04T07:12:07 < dongs> well, 5
2014-01-04T07:12:27 < zyp> angled female headers, you mean?
2014-01-04T07:12:32 < dongs> yeah but less ghetto
2014-01-04T07:12:43 < zyp> I just remember that the ones I got were fucking expensive for what they do
2014-01-04T07:12:46 < dongs> i have a board that another board plugs into
2014-01-04T07:12:53 < dongs> at 90"
2014-01-04T07:13:01 < dongs> thinking to just use 2.54mm right angle but fuck thats ghetto
2014-01-04T07:13:15 < zyp> what about edge connectors? :p
2014-01-04T07:13:24 < dongs> like what?
2014-01-04T07:13:29 < dongs> it cant be too huge either
2014-01-04T07:13:33 < dongs> the plug in board is like 6mm wide
2014-01-04T07:13:40 < dongs> i thought to use pci-e 1x socket
2014-01-04T07:13:42 < zyp> dunno what the price of that is, the card edge is free
2014-01-04T07:13:45 < dongs> and just have board plug in but thats huge
2014-01-04T07:14:11 < zyp> no idea then
2014-01-04T07:14:12 < dongs> card edge would need different thickness pcb
2014-01-04T07:14:14 < dongs> hm ok

2014-01-04T16:14:37 < dongs> maybe that should be my next attempt

2014-01-04T16:19:11 < dongs> 5983 isnt evne on honeywell site..
2014-01-04T16:19:12 < dongs> what he fuck
2014-01-04T16:19:22 < Laurenceb_> 5983L  ?
2014-01-04T16:19:26 < dongs> y
2014-01-04T16:21:21 < Laurenceb_> the ST stuff is just a 5983 in the same package with accel aiuiu
2014-01-04T16:21:24 < Laurenceb_> *-u
2014-01-04T16:22:02 < Laurenceb_> there is a press release somewhere where honeywell say they are shipping it to ST as bare die
2014-01-04T16:22:59 < dongs> Nevertheless, the competition is making important inroads. Geneva-based STMicroelectronics, a leading accelerometer maker, chose Honeywell's magnetoresistive technology over Hall sensors to make the first single-package combination accelerometer-magnetometer on the market. One reason ST cited was that Honeywell's device provides the same sensitivity in all three axes without the need for the magnetic flux concentrators that Hall effect sensors req
2014-01-04T16:23:06 < dongs> yeah
2014-01-04T16:23:16 < dongs> 'bma280 is amazing tho
2014-01-04T16:23:21 < dongs> so fuck ST accels
2014-01-04T16:23:30 < dongs> if im gonna have to route 2 separate SPI buses i might as well just use 2 chips
2014-01-04T16:24:04 < dongs> their shit is just multichip package with each set of pins individually connected.
2014-01-04T16:26:01 < Laurenceb_> there is kionix i guess

2014-01-04T16:26:58 < dongs> The LSM303D is a system-in-package featuring a 3-axis magnetometer and a 3-axis accelerometer. With a 3x3x1mm package size, it belongs to the smallest eCompasses for consumer applications.
2014-01-04T16:27:02 < dongs> The 3-Axis accelerometer uses the TSV process of ST in order to remove the area reserved for I/O pads. The magnetometer dies use the latest process of Honeywell.
2014-01-04T16:27:26 < zyp> I guess wireless usb failed because bluetooth is already filling that niche

2014-01-04T17:20:54 < dongs> its  actually sorta cult in japan as well.
2014-01-04T17:21:05 < dongs> on dvd rental place i got it from there's huge threads of people praising its awesomeness.
2014-01-04T17:22:36 < akaWolf1> why this particular movie?
2014-01-04T17:23:38 < dongs> unsure

2014-01-04T17:26:51 < dongs> oh, right, i got hte jap dvd
2014-01-04T17:29:15 < dongs> The movie has been released on DVD in Russia but has gained virtually no notice elsewhere, with the exception of Japan. This is largely due to the fact that there was no official release of the movie with English subtitles for a long time.
2014-01-04T17:29:19 < dongs> jaja
2014-01-04T17:32:37 < akaWolf1> film only for Russian and Japan :)

2014-01-04T20:06:52 < jpa-> yes
2014-01-04T20:07:22 < Robint91> jpa-, do they require malloc to work?
2014-01-04T20:07:29 < jpa-> yes, of course
2014-01-04T20:07:37 < jpa-> or not malloc, new[]
2014-01-04T20:08:13 < jpa-> strings ok, vector,list,map,set ok, lambda, closures etc. ok, rtti somewhat bloat, iostream pretty bloat, exceptions very bloat
2014-01-04T20:09:21 < Robint91> exceptions meh
2014-01-04T20:11:14 < zyp> I dislike the idea of requiring a heap at all
2014-01-04T20:11:29 < Steffanx> dont forget to use uSTL, made for embedded systems..
2014-01-04T20:11:37 < zyp> so far I've been able to do fine without

2014-01-04T20:12:10 < jpa-> zyp: yeah well, if you need to mangle a lot of strings or similar stuff, a heap is a pretty good solution
2014-01-04T20:12:31 < karlp> isn't the heap where all variables declared inside a function live too?
2014-01-04T20:12:37 < jpa-> no
2014-01-04T20:12:39 < jpa-> that's stack
2014-01-04T20:12:41 < zyp> no, they live on the stack
2014-01-04T20:12:55 < karlp> is heap just for malloc then?
2014-01-04T20:13:00 < zyp> yep
2014-01-04T20:13:22 < zyp> there are in general three storage areas; global, stack and heap
2014-01-04T20:14:07 < zyp> global contains all globals, static class members and static function vars, stack contain all other function vars and heap contains dynamic allocations

2014-01-04T21:05:29 < Steffanx> it was easier than i thought.

2014-01-04T21:05:43 < Steffanx> 1 day.
2014-01-04T21:05:55 < Steffanx> ordered around 16.00 had it the next around 11.00

2014-01-04T21:06:26 < Steffanx> not bad :D

2014-01-04T21:07:25 < Steffanx> Normal "overboeking" ( money transfer??)
2014-01-04T21:07:29 < fbs> ah
2014-01-04T21:07:57 < Steffanx> The process was wonderful, not professional, but perfect
2014-01-04T21:08:39 < Steffanx> You send them an email, like they state on their website. They give you a code, you can enter on their website, so you order online...
2014-01-04T21:08:39 < fbs> 50 ex tax right? how did you pay tax?
2014-01-04T21:09:32 < Steffanx> The make the process a little faster you can send them a proof( just a screenshot ) that you made the payment :D :D :D
2014-01-04T21:10:14 < Steffanx> Uhm, they send you a pro forma invoice which includes the tax.
2014-01-04T21:10:40 < Steffanx> it's pretty straightforward actually.
2014-01-04T21:10:43 < fbs> digikey tax is annoying

2014-01-04T21:12:52 < fbs> nop
2014-01-04T21:13:00 < fbs> gotta pay import stuff and crap at the door
2014-01-04T21:13:02 < fbs> cash
2014-01-04T21:13:04 < Steffanx> never ordered there.. no credit card.

2014-01-04T21:14:34 < Steffanx> mouser does give the option to pay the tax and crap in advance..
2014-01-04T21:15:16 < fbs> never found it at digikey, would save me from a lot of crap
2014-01-04T21:15:59 < fbs> stupid system tho, some shipping companies just send an invoice later
2014-01-04T21:16:18 < Robint91> digikey/ups does that for mee
2014-01-04T21:16:26 < fbs> :o
2014-01-04T21:16:26 < Robint91> no problem with that
2014-01-04T21:16:43 < fbs> did you ask at the door?
2014-01-04T21:17:12 < Robint91> fbs, VAT number or see that the amount that you need to pay at the door is above 150€
2014-01-04T21:17:34 < Steffanx> VAT number.. it so useless to talk with people that have a company :P
2014-01-04T21:17:44 < Robint91> :p
2014-01-04T21:17:53 < Robint91> indeed Steffanx, indeed
2014-01-04T21:18:20 < fbs> i think the guy said i could get a invoice, but when i asked a diff guy he said i couldnt
2014-01-04T21:19:14 < Steffanx> when i read some topics on circuitsonline.net they say to order on nl.digikey.com or digikey.nl so you can pay the VAT.
2014-01-04T21:19:37 < Steffanx> but that excludes the "inklaringskosten" or whatever
2014-01-04T21:19:38 < fbs> maybe its just some import duty at the door
2014-01-04T21:20:49 < fbs> paid 23 on a 149 euro order
2014-01-04T21:23:51 < effractur> inklaringkosten is only after 22 euros
2014-01-04T21:26:00 < Steffanx> Thats incl. shipping costs so if you order only a single component you still have to pay that.
2014-01-04T21:28:12 < effractur> it depence if they put it on your pakket
2014-01-04T21:28:41 < effractur> the chinees guys always do gift and total price 10 dollars
2014-01-04T21:29:08 < fbs> digikey people dont :<
2014-01-04T21:29:16 < Steffanx> but chinese dont care.. digikey does
2014-01-04T21:29:32 < effractur> but does digikey put the shipping with the totalcost of the pakket

2014-01-05T01:03:23 < mrkaroshi> Has anyone here used the DAC of the STM extensively?
2014-01-05T01:03:35 < trepidaciousMBR> I've been using this with the Java software on Linux: http://dangerousprototypes.com/docs/Open_Bench_Logic_Sniffer
2014-01-05T01:03:42 < trepidaciousMBR> mrkaroshi: I've used it a little bit
2014-01-05T01:03:57 < Steffanx> i owned one.. once. It kinda sucked when i had i.
2014-01-05T01:04:11 < Steffanx> It didnt support RLE and stuff back in those ages.
2014-01-05T01:04:11 < mrkaroshi> Ever to send an analogue value to one of it's own ADCs?
2014-01-05T01:04:24 < mrkaroshi> like an internal analogue generated value?
2014-01-05T01:04:47 < trepidaciousMBR> mrkaroshi: You mean connect the DAC output to the ADC input? Isn't that a bit pointless?
2014-01-05T01:04:58 < mrkaroshi> That's coursework for you
2014-01-05T01:05:06 < karlp> I use it for testing driver code :)
2014-01-05T01:05:15 < mrkaroshi> But I came here because I knew at least someone could answer me
2014-01-05T01:05:27 < karlp> there's examples in libopencm3 that sample one channel, output half that channel on the dac, and resample on another adc channel
2014-01-05T01:05:37 < mrkaroshi> It's for exactly that reason karlp
2014-01-05T01:05:49 < trepidaciousMBR> Ah there you go then, coursework auto-complete ;)
2014-01-05T01:06:16 < mrkaroshi> I need to generate a signal at the DAC and receive it at the ADC, then display in various fashions
2014-01-05T01:06:24 < mrkaroshi> libopencm3 you say?
2014-01-05T01:06:24 < karlp> https://github.com/libopencm3/libopencm3-examples/tree/master/examples/stm32/f1/stm32vl-discovery/adc-dac-printf
2014-01-05T01:07:16 < mrkaroshi> That's impressively informative
2014-01-05T01:07:35 < trepidaciousMBR> Steffanx: Logic sniffer sucked? I've found it pretty good, the software is a little weird but it does support RLE now
2014-01-05T01:07:47 < Steffanx> yeah, but not when i owned one
2014-01-05T01:07:49 < Steffanx> sold it :P
2014-01-05T01:08:06 < trepidaciousMBR> Steffanx: Ah right, I've only used two LA's, and the other one was much worse :)

2014-01-05T01:52:38 < mrkaroshi> Can anyone explain how to 'point' DMA buffers at each other on the the STM32?
2014-01-05T01:53:35 < emeb> mrkaroshi: I've used the DACs on some products. What's your concern?
2014-01-05T01:54:37 < mrkaroshi> The one aspect of it that's very new to me is DMA channels for peripherals
2014-01-05T01:54:50 < mrkaroshi> I'm trying to link one to the other like a closed loop
2014-01-05T01:55:09 < mrkaroshi> DMA channels are enabled on both peripherals, in their CRs
2014-01-05T01:55:12 < emeb> so ADC -> DMA -> DAC?
2014-01-05T01:55:31 < mrkaroshi> Precisely
2014-01-05T01:56:00 < emeb> Don't know if that works or not. Never tried it.
2014-01-05T01:56:02 < mrkaroshi> DAC dumps 8-bit value in DAC_DOR1
2014-01-05T01:56:10 < mrkaroshi> ADC_DR needs to receive it
2014-01-05T01:56:22 < emeb> you're backwards
2014-01-05T01:56:34 < emeb> ADC generates data. DAC receives data
2014-01-05T01:57:03 < mrkaroshi> I'm having to generate an analogue signal
2014-01-05T01:57:07 < mrkaroshi> then receive it
2014-01-05T01:57:20 < mrkaroshi> then finally use a USART connection to change it's value
2014-01-05T01:57:29 < mrkaroshi> but I'm not bothered about that right now
2014-01-05T01:58:50 < mrkaroshi> The quote from the brief for the project is: "The voltage source to test the system functionality should be generated using the onboard Digital-Analogue Converter controlled from the serial port."
2014-01-05T01:58:58 < mrkaroshi> Make of that what you will

2014-01-05T02:00:03 < GargantuaSauce> http://xn--d-bga.su/bldc.png so i built this and it doesn't quite work the way i intended
2014-01-05T02:00:20 < GargantuaSauce> it looks like the output can sink current through R1 when both Q5 and Q6 are on (so it should be floating)

2014-01-05T02:06:39 < gxti>  
2014-01-05T02:08:22 < gxti> dang these shitty chinese nrf24l01 modules are cheap, thinking maybe i should just buy a bag of those instead of designing my own thing
2014-01-05T02:08:46 < GargantuaSauce> i am using those, they're pretty sweet
2014-01-05T02:09:09 < fbs> shitty?
2014-01-05T02:09:22 < Steffanx> the new rfmXX modules arent that expensive either anymore..
2014-01-05T02:09:37 < Steffanx> rfm65[some code] ..
2014-01-05T02:09:58 < Steffanx> still twice the price of those chinese nrfs
2014-01-05T02:10:13 < gxti> well, $1 vs $2 makes no difference when my BOM is like $10
2014-01-05T02:10:22 < gxti> and really it's just for random personal stuff so who cares
2014-01-05T02:10:41 < Tectu> so let's say I measure 50°C on a chip (surface). Is there any thumb rule which gives you the core temperature?
2014-01-05T02:10:52 < Tectu> What's the usual heat resistance of a plastic package
2014-01-05T02:11:01 < gxti> it's in the datasheet Tectu
2014-01-05T02:11:02 < Steffanx> nah, more than 2$ :P
2014-01-05T02:11:03 < zyp> it should be listed in the datasheet
2014-01-05T02:12:35 < Tectu> maximum junction temperature 150°C
2014-01-05T02:12:40 < Tectu> that's the core then?
2014-01-05T02:12:44 < Steffanx> you were going for 868mhz not gxti? Thats not 2.4GHz
2014-01-05T02:12:53 < zyp> thermal resistance is usually called R_theta, and is specified as number of degrees per watt dissipated
2014-01-05T02:13:00 < gxti> Steffanx: only because i was starting from scratch. 2.4ghz will work too.
2014-01-05T02:13:06 < gxti> 915mhz though
2014-01-05T02:13:16 < Steffanx> oh, close enough
2014-01-05T02:13:22 < zyp> usually there is a couple of numbers listed like junction to case and case to ambient, or even junction to ambient
2014-01-05T02:13:26 < gxti> the FCC might disagree there
2014-01-05T02:14:18 < Steffanx> yeah.
2014-01-05T02:14:34 < gxti> rfm65w has interesting features but probably not worth it, especially since it doesn't have onboard antenna
2014-01-05T02:15:36 < zyp> Tectu, say your device has a T_J_max of 150°C, R_th_JA of 50 °C/W and you're speccing it to operate at an ambient temperature of 50°C
2014-01-05T02:15:58 < zyp> that means you can allow a temperature difference of 100°C, which means that you at most can dissipate 2W
2014-01-05T02:16:09 < Tectu> zyp, yeah, I am just recalling from my education :P
2014-01-05T02:16:15 < Tectu> I always HATED it to calculate temperature stuff
2014-01-05T02:16:32 < zyp> but it was so simple :p
2014-01-05T02:16:36 < gxti> seems pretty simple but i didn't have it for homework
2014-01-05T02:16:43 < gxti> i'm sure those were pretty contrived
2014-01-05T02:16:57 < gxti> 3 chips and 5 heatsinks and a goat
2014-01-05T02:17:11 < Tectu> also note this guy who uses four wallwarts in parallel to get some more current out of them... not sure if that's sane to do?  http://s21.postimg.org/vdf0g9d53/Power_Supply4x15_Vx1600m_A.jpg
2014-01-05T02:17:34 < gxti> it's incredibly stupid
2014-01-05T02:17:34 < zyp> no, it's not
2014-01-05T02:18:08 < zyp> you're not guaranteed that they are 100% equal, so you'll get uneven load distribution
2014-01-05T02:18:30 < gxti> cheap wall warts can barely maintain regulation by themselves, expecting them to load share is idiocy
2014-01-05T02:18:53 < zyp> which you can somewhat mitigate by putting a resistor in series with each supply, but then you don't have a constant voltage anymore
2014-01-05T02:21:41 < Tectu> what happens when they are unequally loaded?
2014-01-05T02:22:06 < gxti> one takes all the current and goes into limiting or explodes
2014-01-05T02:23:20 < GargantuaSauce> so uh having a simulator is all fine and well but i still dunno how to mitigate this issue
2014-01-05T02:24:00 < GargantuaSauce> the obvious solution is to stick a diode between Q2 and the output but that means Vgs on X1 will be at least 2 diode drops which is not off enough for my tastes
2014-01-05T02:25:28 < zyp> what's the problem?
2014-01-05T02:26:24 < GargantuaSauce> when the enable line is low, thus Q5 and Q6 are on, the output can sink current to ground backwards through Q2 and R1

2014-01-05T02:31:45 < zyp> what about replacing R2 with a pfet and Q5 with a pulldown to the output to make it symmetric to Q6/R4?
2014-01-05T02:35:28 < GargantuaSauce> and driving its gate with another nfet+pullup?
2014-01-05T02:41:16 < zyp> something like that
2014-01-05T02:41:19 < GargantuaSauce> that is probably the best bet i guess, or would be if i had pfets handy <_<
2014-01-05T02:42:16 < GargantuaSauce> maybe i'll just add another nfet between r2 and the output and drive it with q5 and a pullup

2014-01-05T03:48:53 < GargantuaSauce> oh and the bjts are 3904/6
2014-01-05T03:51:08 < GargantuaSauce> it definitely works except for sinking some current in "disabled" mode
2014-01-05T03:51:18 < GargantuaSauce> ive tried both super slow switching and a few khz
2014-01-05T03:52:20 < GargantuaSauce> i am kinda tempted to just increase the base resistance, limit switching freq and ignore the issue
2014-01-05T03:53:44 < GargantuaSauce> tbh i am surprised i didn't screw up enough that there's significant shoot through and magic smoke

2014-01-05T04:17:29 < emeb_mac> ho
2014-01-05T04:17:35 < englishman> im working on a SPI peripheral with F3 and keil debugger
2014-01-05T04:17:46 < emeb_mac> fun!
2014-01-05T04:17:47 < englishman> SPI doesnt seem to do anything when i'm stepping through
2014-01-05T04:17:54 < englishman> but works when i let it run
2014-01-05T04:18:02 < englishman> very fun
2014-01-05T04:18:05 < emeb_mac> dma or polled?
2014-01-05T04:18:09 < englishman> polled

2014-01-05T05:17:28 < dongs> maybe youre trying to spi before turning it on?
2014-01-05T05:17:35 < dongs> and then later turn on, reset, debug, and its still on

2014-01-05T05:52:13 < englishman> stepping through debugger, i call SPI_SendData8(blah) but the DR doesnt change

2014-01-05T05:53:49 < dongs> heres my working non-DMA spi

2014-01-05T05:54:15 < gxti> baird: seemed appropriate anyway
2014-01-05T05:54:17 < englishman> RCC is set yes
2014-01-05T05:54:21 < englishman> did not read first
2014-01-05T05:55:49 < englishman> if it read first it also does not change DR
2014-01-05T05:56:40 < dongs> how about just using my function.
2014-01-05T05:56:41 < dongs> since it works.
2014-01-05T05:57:00 < englishman> cause its F3
2014-01-05T05:57:16 < englishman> o wait just saw your bcas
2014-01-05T05:57:27 < dongs> doesnt matter its same shit
2014-01-05T05:57:28 < dongs> oh F3
2014-01-05T05:57:31 < dongs> you need to disable fiqo
2014-01-05T05:57:32 < dongs> fifo
2014-01-05T05:57:33 < dongs> or somesthi
2014-01-05T05:57:34 < dongs> uh sec
2014-01-05T05:58:02 < dongs>     SPI_RxFIFOThresholdConfig(SPI2, SPI_RxFIFOThreshold_QF);
2014-01-05T05:58:06 < GargantuaSauce> f0 is the same right
2014-01-05T05:58:09 < GargantuaSauce> yeah you have to lower the watermark
2014-01-05T05:58:14 < GargantuaSauce> thing
2014-01-05T05:59:55 < englishman> only thing i see is SPI_RxFIFOThresholdConfig
2014-01-05T06:00:09 < englishman> sets when RXNE event is generated
2014-01-05T06:00:09 < dongs> thats what i just pasted
2014-01-05T06:00:15 < dongs> SPI_RxFIFOThresholdConfig(SPI2, SPI_RxFIFOThreshold_QF);
2014-01-05T06:00:17 < dongs> do this.
2014-01-05T06:00:19 < dongs> at init.
2014-01-05T06:00:22 < dongs> then it works.

2014-01-05T20:36:26 < Tectu> when I free() a struct, is it correct that GDB still shows up the structs content?
2014-01-05T20:36:35 < Tectu> (as it does not clear the memory)
2014-01-05T20:36:58 < GargantuaSauce> yes
2014-01-05T20:37:26 < GargantuaSauce> though you are doing it wrong if you don't set the pointer to 0 or something valid as soon as you've free()'d the thing it points to
2014-01-05T20:37:55 < karlp> free(u32*) { *u32 = 0}
2014-01-05T20:39:28 < Tectu> pointer still points...
2014-01-05T20:39:53 < jpa-> it's a good idea to set the pointer to NULL, but free() will not do it automatically
2014-01-05T20:40:04 < Tectu> okay, thanks!
2014-01-05T20:40:07 < Tectu> (why doesn't it do that?)
2014-01-05T20:40:11 < Tectu> I assume there's some sane reason for that
2014-01-05T20:40:34 < GargantuaSauce> uh because pointers are passed by value?
2014-01-05T20:40:42 < GargantuaSauce> and free(void**) would be silly
2014-01-05T20:40:55 < Tectu> ah, right...
2014-01-05T20:42:02 < fbs> or a 'void * free (void *)'

2014-01-05T20:43:04 < Tectu> probably some silly question but how does one check whether his destroy routine works then? Allocate a new object of the same size and hope it will be using that free'd space?
2014-01-05T20:43:19 < karlp> "destroy" ?
2014-01-05T20:43:35 < Tectu> -> any routine that calls free() in this case
2014-01-05T20:43:39 < zyp> yeah, that's a silly question
2014-01-05T20:43:54 < jpa-> Tectu: dmalloc or valgrind check that malloc() and free() are used correctly
2014-01-05T20:45:12 < zyp> C++ could pass the pointer as a reference and thereby have it set to null
2014-01-05T20:45:19 < zyp> but there are good reasons not to do that
2014-01-05T20:45:58 < zyp> because for it to work, the pointer has to actually be stored in memory, which is a silly requirement
2014-01-05T20:46:03 < jpa-> in C++ i wouldn't use free() anyway and avoid delete also.. unique_ptr and friends are so much better
2014-01-05T20:46:10 < zyp> yes
2014-01-05T20:46:17 < Tectu> why would you avoid delete?
2014-01-05T20:46:26 < jpa-> Tectu: because it is easy to get wrong
2014-01-05T20:46:27 < zyp> because RAII is nice
2014-01-05T20:46:36 < jpa-> zyp: well if it was inline, it wouldn't need to be in memory really
2014-01-05T20:47:10 < Tectu> jpa-, sorry but can you give an example?
2014-01-05T20:47:19 < zyp> jpa-, fair point, still breaks the C macro logic
2014-01-05T20:47:37 < zyp> consider this: free(get_some_object());
2014-01-05T20:47:40 < jpa-> Tectu: of how it is easy to make a mistake in memory allocations? i bet you've found plenty of them yourself by this point
2014-01-05T20:48:38 < fbs> i wouldnt use c++
2014-01-05T20:48:46 < jpa-> fbs: why not?

2014-01-05T20:49:32 < jpa-> i wish there was a good microcontroller-friendly STL.. libstdc++ is not bad, but some parts of it are
2014-01-05T20:49:49 < Tectu> one would rewrite ugfx in cpp then
2014-01-05T20:50:06 < jpa-> in C you just need to be careful
2014-01-05T20:50:14 < jpa-> and have a good test set
2014-01-05T20:50:17 < jpa-> and pray
2014-01-05T20:50:23 < Tectu> jpa-, that's why I am bothering you guys with those questions ;)

2014-01-05T20:50:43 < Tectu> may one also tell me the difference between a 'panic' and an 'assert' ?
2014-01-05T20:50:51 < jpa-> fbs: basically, aim to test as much of the code as possible on a PC first
2014-01-05T20:51:06 < zyp> Tectu, panic is what you do when you fail an assertion
2014-01-05T20:51:37 < jpa-> also, memory bugs are difficult to catch with specific tests.. much more likely to catch them with general test cases running under instrumentation (like assert(free_memory_after_test == free_memory_before_test))
2014-01-05T20:51:40 < Tectu> jpa-, that's the nice part about the linux port of ugfx :3
2014-01-05T20:51:59 < jpa-> Tectu: yeah well, any sane library would do the same
2014-01-05T20:52:08 < Tectu> jpa-, as soon as you fire that assert, you still have to do a lot of debugging work
2014-01-05T20:52:13 < Tectu> (to catch the actual problem)
2014-01-05T20:52:17 < jpa-> of course
2014-01-05T20:52:21 < Tectu> jpa-, indeed. ugfx did it quite late
2014-01-05T20:52:26 < jpa-> but debugging is easy when you have a reproducible test case
2014-01-05T20:52:28 < GargantuaSauce> my qualm with c++ on a micro is that there are multiple language features that are tightly coupled to the standard library
2014-01-05T20:52:39 < GargantuaSauce> and the standard library is designed for running under an os
2014-01-05T20:52:59 < jpa-> GargantuaSauce: hmm, anything besides exceptions?
2014-01-05T20:53:22 < zyp> GargantuaSauce, «some foods are too spicy for me, so I dislike food»
2014-01-05T20:53:49 < GargantuaSauce> exceptions are the big one, there are a few others particularly among the fancy new features
2014-01-05T20:53:51 < jpa-> most of libstdc++ runs pretty fine without operating system.. and it is not that large either
2014-01-05T20:54:03 < jpa-> GargantuaSauce: hmm, can you elaborate?
2014-01-05T20:54:03 < GargantuaSauce> dont get me wrong i love c++
2014-01-05T20:55:02 < zyp> my problem with that argument is that C still gives you no advantage over using C++ and just avoiding those particular features

2014-01-05T20:59:49 < zyp> jpa-, I've considered writing my own smart pointer stuff which lets you specify allocation area, so you can allocate objects from fixed pools instead of a systemwide heap
2014-01-05T21:00:22 < GargantuaSauce> that's a good point zyp, but not using exceptions has some pretty far-reaching issues does it not
2014-01-05T21:00:33 < GargantuaSauce> like half of the stl classes wanting to throw them
2014-01-05T21:00:47 < jpa-> zyp: doesn't the stl smart pointer templates also allow specifying an allocator?
2014-01-05T21:00:55 < zyp> do they?
2014-01-05T21:01:06 < jpa-> IIRC yes
2014-01-05T21:01:19 < jpa-> or deleter anyway, usually they don't care about allocation
2014-01-05T21:01:27 < zyp> yes, of course
2014-01-05T21:01:41 < zyp> ah, yeah, you're right
2014-01-05T21:01:46 < jpa-> though if i were to use it in a system, i would just have one system-wide deleter that just does a few comparisons to see where the pointer belongs

2014-01-05T21:02:05 < jpa-> much less hassle
2014-01-05T21:02:23 < zyp> sounds slow
2014-01-05T21:03:20 < jpa-> a few integer comparisons is not much compared to rest of malloc/free
2014-01-05T21:03:38 < jpa-> GargantuaSauce: hmm, the libstdc++ implementation seems to work pretty well without exceptions (one just has to declare functions like these   https://github.com/PetteriAimonen/dso-quad-logic/blob/master/cxxglue.cc )
2014-01-05T21:04:08 < GargantuaSauce> hah, okay
2014-01-05T21:04:15 < zyp> jpa-, yes it is, when you consider that this can be used with fixed object size pools which just keep a stack of free object
2014-01-05T21:04:42 < jpa-> zyp: true enough.. though it has to be pretty speed-critical for it to matter
2014-01-05T21:05:17 < GargantuaSauce> anyway i guess my point is just that there's hoops like that to jump through....obviously it's not a show stopper
2014-01-05T21:07:06 < zyp> I've also considered experimenting with exceptions

2014-01-05T21:07:35 < jpa-> GargantuaSauce: yeah well.. with C the first hoop you need to jump through is to find a string implementation that is not O(n^2) ;)
2014-01-05T21:07:57 < zyp> done right, exceptions should have less overhead than lots of error code checking throughout the call stack
2014-01-05T21:08:25 < jpa-> yeah, i wonder why there seems to be no lightweight exception implementation for cortex-m3
2014-01-05T21:08:40 < jpa-> the libstdc++ one looks to be like >50kB, if it even works

2014-01-06T00:28:07 < gxti> surprisingly few ICs that could serve a similar purpose to the VBAT pin
2014-01-06T00:28:39 < gxti> lazy and probably smart answer is just plop down two schottky diodes and live with the volt drop

2014-01-06T09:39:38 < jpa-> yeah, i did nothing special
2014-01-06T09:40:14 < jpa-> AFAIK Rext is a ghost that lingers around any crystal oscillator confusing people, but is only summoned in special situations such as testing the robustness of the oscillator against crystal variations
2014-01-06T09:41:59 < qyx_> i have always used 390ohm on stm32, but it works without

2014-01-06T14:45:45 < Robint91> yes
2014-01-06T14:46:20 < Laurenceb> wtf
2014-01-06T14:46:25 < Laurenceb> usb isnt doing anything
2014-01-06T14:46:30 < Steffanx> How? Connect your usb thingy and view the images :P
2014-01-06T14:46:38 < Robint91> OTG cable
2014-01-06T14:46:43 < Laurenceb> arg
2014-01-06T14:46:56 < Steffanx> :P
2014-01-06T14:47:11 < Laurenceb> nothing happening with micro B
2014-01-06T14:47:14 < Laurenceb> how do i hack it?
2014-01-06T14:47:52 < Steffanx> meh, im screwed.. designed this pcb for a case that is no longer sold :(
2014-01-06T14:48:01 < Steffanx> *enclosure
2014-01-06T14:48:59 < Laurenceb> arg wtf
2014-01-06T14:49:03 < Laurenceb> its usb host
2014-01-06T14:49:27 < Steffanx> What did you expect Laurenceb?
2014-01-06T14:49:49 < Laurenceb> i was hoping you could load to ram
2014-01-06T14:50:11 < Laurenceb> i dont have the right cable
2014-01-06T14:50:42 < Steffanx> The demo isn't that interesting anyway. It feels slowish.
2014-01-06T14:50:59 < Laurenceb> clearly needs chibios
2014-01-06T14:51:16 < Steffanx> and µGFX
2014-01-06T14:53:25 < zyp> Laurenceb, pull the USB_ID line low, that's what distinguishes A connectors from B connectors
2014-01-06T14:53:48 < zyp> A has it wired to ground while B lets it float
2014-01-06T14:54:12 < Laurenceb> ok
2014-01-06T14:54:21 < Laurenceb> but id still need a usb drive
2014-01-06T14:54:23 < zyp> of course, don't do that when you have it connected to another host, only use it for ghettowiring it to a device :p
2014-01-06T14:54:28 < Laurenceb> ill see what i can find

2014-01-06T17:55:55 < zyp> the device in particular is a gpio expander, it's sitting on a customer board for handling panel IO
2014-01-06T17:56:06 < zyp> what happens is that false keypresses are detected
2014-01-06T17:57:38 < zyp> and it doesn't seem to be a problem related to my code either, I'm getting no error codes from the i2c periph driver on the platform (which I didn't write), and my buffer that I store to doesn't get overwritten by an overflow either

2014-01-06T17:58:48 < zyp> the fun thing is that this is easily reproducible during flash write (I'm not sure if it happens otherwise, but it may)
2014-01-06T18:00:25 < zyp> so I suspect that there's some weird corner case race condition between the periph and the periph driver, which is triggered by the additional interrupt latency imposed by the flash write operation making the flash busy

2014-01-06T18:21:22 < Tectu> I'm never sure wheter I should use enums or #defines for flags...
2014-01-06T18:21:29 < Tectu> any advice/rule?
2014-01-06T18:22:16 < zyp> I have a couple of simple rules
2014-01-06T18:22:22 < zyp> 1. avoid defines
2014-01-06T18:22:52 < zyp> hmm, I think that's mostly it
2014-01-06T18:23:54 < Tectu> helpful as always :)
2014-01-06T18:24:26 < zyp> anyway, do you know of any advantages with defines over enums for this particular case?
2014-01-06T18:25:48 < Tectu> not really. But I lack the experience that's why I ask you guys.
2014-01-06T18:27:00 < karlp> #define is more twitter friendly
2014-01-06T18:27:12 < Tectu> enums seem nicer as you can typdef them to a name with some relations
2014-01-06T18:27:22 < Tectu> something like     buttonsflags_t

2014-01-06T18:31:49 < Tectu> but with defines you can do or-operations. with enums you cant? (unless you assign each value manually)
2014-01-06T18:32:19 < zyp> huh?
2014-01-06T18:32:55 < gxti> ORing enums doesn't make sense conceptually, if not technically
2014-01-06T18:33:15 < Tectu> enum flag_t { flag0, flag1, flag2, flag3 };      ->   if you      flag1 | flag2 you're lost
2014-01-06T18:33:20 < Tectu> as they are not really flags
2014-01-06T18:33:26 < zyp> enum {A, B, C}; printf("%d", B|C); is perfectly valid, it'll print 3.
2014-01-06T18:33:40 < Tectu> ah lol, binary fail. sorry.
2014-01-06T18:33:43 < gxti> but is that expressly permitted by the spec? you end up with a value that's not in the enum
2014-01-06T18:33:56 < Tectu> school begun again so brain dead again
2014-01-06T18:33:58 < gxti> i seem to remember some gcc flags about that
2014-01-06T18:34:00 < zyp> enums are integer, by spec
2014-01-06T18:34:11 < gxti> integer with extra promises...
2014-01-06T18:34:31 < zyp> yes, you're promised that it's an integer type large enough to hold all values
2014-01-06T18:34:52 < gxti> -fstrict-enums for example
2014-01-06T18:35:00 < zyp> and bitwise combining two values wouldn't yield a value larger than the one you started with
2014-01-06T18:35:15 < gxti> this is why i'm saying it's conceptually invalid, not technically invalid
2014-01-06T18:35:32 < gxti> an enum is an enumeration of all possible values, using it for bitfields seems like a mismatch
2014-01-06T18:36:55 < gxti> lunchtime
2014-01-06T18:37:49 < zyp> for typed enumerations that makes sense
2014-01-06T18:38:51 < zyp> but the «enumeration of all possible value» argument doesn't hold for anonymous enums, since there is no type to bind them together at that point
2014-01-06T18:39:18 < zyp> the enumeration thing is nice when you have stuff like a switch, where you can check that all cases are handled
2014-01-06T18:39:28 < zyp> but that's not the only thing enums are useful for
2014-01-06T18:41:08 < zyp> enums are by definition integer constants, macros are substituted text, and all you want is an integer constant
2014-01-06T18:42:27 < zyp> also, from a C++ perspective, enums have another important advantage, namely scope/namespace

2014-01-07T06:18:37 < dongs> its not liek anyone actually LISTENS to stuff rockbox outputs.
2014-01-07T06:18:45 < dongs> i installed it on a super old ipodnano 2gb or something yeras ago
2014-01-07T06:19:00 < dongs> comparing side by side audio quality of jewpod original firmware  + rockbox it was like w h o a
2014-01-07T06:19:40 < emeb_mac> whoa rockbox better or whoa rockbox sux?
2014-01-07T06:20:40 < dongs> totally sux
2014-01-07T06:21:01 < dongs> it was lacking highs, the soundstage felt very cramped, the lows weren't low enough, etc
2014-01-07T06:21:27 < emeb_mac> heh "soundstage". sounds totally audiophool
2014-01-07T06:21:40 < dongs> a complete sensory disaster
2014-01-07T06:22:26 < emeb_mac> I've got rockbox on an Archos - sounds the same, but that one uses a dedicated MP3 codec chip, so all it changes is the user interface.
2014-01-07T07:03:46 < GargantuaSauce> i find the concept of dongs saying "cramped soundstage" without irony hard to swallow

2014-01-07T12:00:51 < dongs> i 'd use them cuz they're cheaper
2014-01-07T12:00:55 < dongs> but they dont have r/c colored wires
2014-01-07T12:01:03 < dongs> if you dont care color or wahtever kr might be cheapefr
2014-01-07T12:01:19 < zyp> I need 4-pin xh on one end and blade connectors on the other

2014-01-07T12:05:48 < dongs> what qyx said
2014-01-07T12:05:53 < dongs> those flat shits usually need a bit fatter cable
2014-01-07T12:06:04 < qyx_> i use 1mm^2
2014-01-07T12:06:09 < qyx_> dont know which awg
2014-01-07T12:06:23 < qyx_> also the smaller ones (4.8mm) can accept 0-5-0.75
2014-01-07T12:06:33 < zyp> that sounds thick, the red ones are usually rated 0.75-1.5
2014-01-07T12:06:55 < zyp> and 0.75 is kind of unnecessary thick
2014-01-07T12:07:00 < qyx_> red are the smallest, arent they?
2014-01-07T12:07:03 < qyx_> or blue
2014-01-07T12:07:10 < zyp> blue is larger
2014-01-07T12:07:23 < zyp> but I think there are green ones that are even smaller, but more uncommon
2014-01-07T12:07:39 < dongs> ok, ill ask and see what they say
2014-01-07T12:07:55 < dongs> how many?
2014-01-07T12:07:58 < qyx_> standard PC supply wires are awg18
2014-01-07T12:07:58 < zyp> oh, and I need it to be the 6.3mm kind, not the 4.8mm kind qyx_ mentioned
2014-01-07T12:08:16 < zyp> doesn't have to be that thick
2014-01-07T12:08:30 < zyp> awg24 is probably good
2014-01-07T12:09:38 < zyp> http://www.ebay.com/itm/290961637912 <- I've been using shit like this and cutting off one end and recrimping
2014-01-07T12:09:51 < dongs> lol
2014-01-07T12:10:32 < dongs> anywa,y how many wires for quote?
2014-01-07T12:10:34 < dongs> like 100 or something?
2014-01-07T12:10:57 < zyp> 100-500
2014-01-07T12:11:01 < dongs> ok

2014-01-07T12:13:01 < zyp> yep
2014-01-07T12:14:12 < dongs> i foxconned 24 jewpad boards today, all gone in like 3 hours
2014-01-07T12:17:02 < Claude> foxconned ^^
2014-01-07T12:23:55 < baird> thrown off the roof of a tall building?
2014-01-07T12:24:35 < qyx_> f050 in qfn24 doesn't have vbat o\
2014-01-07T12:26:16 < Claude> covered in aluminium dust
2014-01-07T12:26:45 < qyx_> i was about to abuse it for vdd monitoring
2014-01-07T12:27:54 < karlp> isn't vbat _for_ vdd monitoring?
2014-01-07T12:28:11 < qyx_> no, it's backup for rtc
2014-01-07T12:28:20 < dongs> how doyou abuse it
2014-01-07T12:28:20 < qyx_> ir maybe yes
2014-01-07T12:28:22 < dongs> does it go to some adc?
2014-01-07T12:28:27 < qyx_> yep
2014-01-07T12:28:29 < dongs> neat
2014-01-07T12:28:55 < qyx_> with internal disconnectable divider
2014-01-07T12:29:11 < dongs> amazing. i never read that shit
2014-01-07T12:30:16 < zyp> huh, that's cool
2014-01-07T12:30:52 < karlp> I thought it was just a pin that was allowed to go higher than vdd, and had the divider
2014-01-07T12:31:05 < karlp> didn't know it was backup for rtc as well
2014-01-07T12:31:18 < karlp> so what have you and gxti been complaining about for days now then?
2014-01-07T12:31:26 < karlp> that the pin isn't available on allpackages or something?
2014-01-07T12:33:31 < qyx_> it isn't
2014-01-07T12:33:47 < qyx_> afk
2014-01-07T12:47:14 < jpa-> if you are monitoring Vdd (not battery voltage) why would you need vbat? just read internal reference and calculate from there?
2014-01-07T12:48:00 < dongs> not wasting a pin i guess
2014-01-07T12:48:08 < jpa-> though i never found vbat very useful for monitoring battery voltage either, wasn't it limited to 3.6V or something?
2014-01-07T12:48:11 < dongs> since vbat is wasted anyway.
2014-01-07T13:05:10 < Robint91> select avdd as ref and measure the internal ref
2014-01-07T13:05:14 < Robint91> works for me

2014-01-07T14:25:36 < qyx_> jpa-: 1/2 internal divider
2014-01-07T14:25:53 < qyx_> ah, it is, but for li primary cell it is okay
2014-01-07T14:26:48 < jpa-> yeah.. though for li primary i would just feed Vdd from it without regulator directly
2014-01-07T14:27:03 < qyx_> yep, without regulator
2014-01-07T14:27:09 < jpa-> and if Vadc_ref = Vdd, then you can just compare against Vref_int and no need for Vbat
2014-01-07T14:27:32 < jpa-> like Robint91 also said :P
2014-01-07T14:27:40 < qyx_> i will do the same probably

2014-01-07T15:56:05 < GargantuaSauce> hMMMmm
2014-01-07T15:56:48 < GargantuaSauce> it's almost like running a 200kW device thrown together by amateurs in sustained operation is a bad idea

2014-01-08T11:56:06 < zyp> but not the flat ones
2014-01-08T11:56:17 < dongs> right, they dont have those, but im sure my other china pal does
2014-01-08T11:56:55 < zyp> yeah. those should be cheap, considering how common they are
2014-01-08T11:57:33 < zyp> that's good, that was the price range I was hoping for
2014-01-08T11:58:35 < dongs> i'm mostly sure jst is included cuz she asked whether need male or female and since they do rc trash that shit should be there for battery balanace leads or wahtever

2014-01-08T13:10:34 < jpa-> bah, my debug cable has enough capacitance so that if i plug it to a board while running, it causes a sufficient pulse on NRST to reset the controller
2014-01-08T13:10:44 < jpa-> i wonder if i should put a capacitor on the NRST on the board..
2014-01-08T13:11:44 < jpa-> naturally it would help if NRST was connected somewhere at the other end of the cable..

2014-01-08T15:26:59 < dongs> i did it with afroled driver
2014-01-08T15:27:06 < dongs> but i just put some leaded solder on pad and hotaired it
2014-01-08T15:27:08 < dongs> then did the legs.
2014-01-08T15:27:16 < zyp> I just told one of my coworkers that I could do it
2014-01-08T15:27:20 < Laurenceb> www.satansrapture.com/satanseed.htm
2014-01-08T15:27:23 < zyp> yeah, that's what I figure should work
2014-01-08T15:27:34 < zyp> he apparently blew up the old chip
2014-01-08T15:27:56 < zyp> some integrated audio output stage
2014-01-08T15:29:00 < zyp> apparently a probe slipped while measuring, and shorted vcc to the buffer-cap pin for an internal vreg
2014-01-08T15:29:04 < jpa-> if the thermal pad extends a bit outside the edges of the chip, it is easy even without hotair
2014-01-08T15:29:18 < zyp> I don't think it does
2014-01-08T15:29:48 < zyp> but I have a hotair station, so I believe it should be fine
2014-01-08T15:30:10 < jpa-> yeah
2014-01-08T15:32:27 < zyp> probably a larger problem that some of the pads disappeared when somebody removed the old chip :p

2014-01-08T15:47:29 < jpa-> zyp: well still not that bad if the traces are going outwards from the chip :P
2014-01-08T15:48:43 < zyp> IIRC it was a ground, a couple of vccs that are next to bypass caps, the pad for the vreg cap on the bottom, and some signal that's also routed on the bottom
2014-01-08T15:49:09 < zyp> so I'll probably have to run a wire around to the bottom, unless I just move the vreg cap to the top
2014-01-08T15:49:32 < zyp> and run a wire over to another chip that have the same signal hooked up

2014-01-08T17:22:20 < jpa-> i've done it some time, but not on STM32
2014-01-08T17:22:49 < jpa-> should be pretty simple if you have a timer input on the RX pin or atleast an EXTI is available (.. or if you can busyloop ..)
2014-01-08T17:23:28 < karlp> you have to have some known pattern to look for though right?
2014-01-08T17:24:33 < jpa-> not really.. i would go just with "look for a 10 transitions or so, pick minimum time as bit length, go with it"
2014-01-08T17:24:37 < gxti> that's really only required if you want the hardware to do it (if stm32 even has that)

2014-01-08T17:25:06 < jpa-> if you get frame error or garbage data (if you can detect that), go back to start
2014-01-08T17:26:20 < jpa-> more advanced version: collect a few transitions, find the greatest common divisor
2014-01-08T17:26:39 < gxti> ideally with some filtering/bucketing so you don't get thrown off by a glitch
2014-01-08T17:27:29 < jpa-> yeah.. it is easier if you have a robust protocol that can handle lost data & error check received stuff

2014-01-09T03:01:11 < fbs> anyone familiar with this board? https://www.olimex.com/Products/ARM/ST/STM32-E407/
2014-01-09T03:03:48 < dongs> what about it? just looks like a F4 breakout
2014-01-09T03:05:31 < fbs> uhu
2014-01-09T03:06:17 < dongs> where the fuck is jtag connector
2014-01-09T03:06:46 < dongs> an ARDUINO compatible platform connector is also available. ????????????????????????????????
2014-01-09T03:10:43 < fbs> :p
2014-01-09T03:11:46 < dongs> anyway i dont see anything special about it. if there's a proper jtag/swd on tehre then it just works.
2014-01-09T03:11:51 < dongs> all you need to know is in schematic.
2014-01-09T03:11:59 < dongs> xtal is 12mhz, so you'll need to change pll multiplier from default/sample code.
2014-01-09T03:12:25 < fbs> just wondered if anyone tried it

2014-01-09T04:05:34 < upgrdman> its actually really maneuverable yet stable.
2014-01-09T04:06:33 < baird> gxti: random. I tried that with a voltage doubler and an MSP430. I got a 16x2 display to work, but the 40x4's wouldn't (but they were also a different brand)
2014-01-09T04:06:53 < gxti> the brand is 'cheap shit from aliexpress'
2014-01-09T04:06:57 < gxti> so we'll see i guess

2014-01-09T05:02:12 < qyx_> I have two jobs. The first one is basic. I need to create the files necessary to manufacture pcb for hashing. The two primary objectives are low cost to produce and high hash rate
2014-01-09T05:02:16 < qyx_> lol @ freelancer
2014-01-09T05:02:56 < mtbg> what hashing?
2014-01-09T05:02:58 < upgrdman> hashing?
2014-01-09T05:02:59 < upgrdman> lol
2014-01-09T05:03:04 < qyx_> bitcoins
2014-01-09T05:03:53 < mtbg> btw
2014-01-09T05:05:06 < mtbg> I recently bought two spartan6 boards (namely ztex 1.15x) for like 22 usd each (the fpga alone is worth ~150 usd)
2014-01-09T05:05:28 < mtbg> someone who sold it have had it only for btc mining
2014-01-09T05:05:42 < mtbg> and as some asics became available
2014-01-09T05:06:27 < qyx_> maybe
2014-01-09T05:06:32 < mtbg> fpga mining was not giving enough rate
2014-01-09T05:08:30 < baird> I find picking up dropped 5 cent pieces at the supermarket pays better. :P
2014-01-09T05:10:11 < englishman> nuh uh buttcoins = instant boats and jets
2014-01-09T05:10:35 < englishman> "i started mining them when they were worth about .75 cents each. laugh all you want about them. they paid for a new retinal macbook, 3 new cameras, 3 new canon L lenses, 2 months vacation in south america, a dji f55o, a new phantom 2 and a gopro3+ and i havent had to work for the last two years all from a 600$ investment in a bitcoin mining computer."
2014-01-09T05:11:07 < mtbg> primecoin is still worth mining on pc
2014-01-09T05:11:18 < mtbg> as there is no dedicated hardware
2014-01-09T05:11:32 < qyx_> all scrypt-based coins
2014-01-09T05:11:54 < mtbg> prime is not scrypt :>
2014-01-09T05:12:12 < qyx_> hm, what hash does it use?
2014-01-09T05:12:34 < qyx_> ah
2014-01-09T05:12:37 < mtbg> sha256, but that is the easy part of the work you have to do
2014-01-09T05:12:50 < qyx_> search of prime numbers
2014-01-09T05:12:58 < qyx_> *for
2014-01-09T05:13:27 < mtbg> the harder part is that the hash must be an origin of a cunningham chain of either type of length longer or equal given
2014-01-09T05:14:23 < mtbg> well, not the hash itself must be the origin but the hash * some N
2014-01-09T05:14:41 < mtbg> N can be 1, but usually isn't
2014-01-09T05:17:22 < baird> englishman: And I've heard of a few people who inherited bankrupt mining companies and now they're billionaires...
2014-01-09T05:17:30 < mtbg> I wondered if it would be worth to transfer some of the work needed to some hardware, and it seems that the two ztex boards I have would give the same hash rate as 6x3.5GHz amd64
2014-01-09T05:19:54 < mtbg> it would be neat to have a comparison of sequential computational performance per price for various devices which can compute
2014-01-09T05:20:45 < mtbg> because the problem can be parallelized to up to ~1M of independend parallel instances, each needing a few bytes of memory
2014-01-09T05:21:23 < mtbg> and there are some microcontrollers for a few dozen cents which can do like 50MHz
2014-01-09T05:21:38 < mtbg> all the arithmetic is integer
2014-01-09T05:25:15 < englishman> let me tell you about this amazing opportunity that people are talking about
2014-01-09T05:28:21 < mtbg> what opportunity?
2014-01-09T05:28:25 < baird> englishman: it allows any super-skillful teenager to Make Money Fast!
2014-01-09T05:29:47 < baird> ..and when mining for whatever crypto-coin doesn't make enough, you just invent another one and grab the super-easy calculated coins before it gets popular.
2014-01-09T05:32:48 < mtbg> what is the cheapest cortex microcontroller any of you is aware?
2014-01-09T05:36:37 < englishman> M0?
2014-01-09T05:37:04 < englishman> LPC1111?
2014-01-09T05:37:35 < mtbg> I think LPC1102 is cheaper
2014-01-09T05:39:22 < englishman> for me, stm32f0 is the cheapest on digikey
2014-01-09T05:39:32 < englishman> F030K6T6
2014-01-09T05:47:35 < gnomad> I saw some of the NXPs as cheap as 67 cents qty1 on avnet a while back...

2014-01-09T12:46:13 < baird> Fuck wireless broadband-- it's the Conservative government forcing us onto the Telstra monopoly here. Everyone wants the real thing.
2014-01-09T12:51:00 < baird> While much of the stat is made up of smartphones, almost half of residential boradband is using Mobile data because Tesltra have intentionally not provided ADSL-capable exchanges in new housing developments & etc. Was nice of John Howard to remove that little obligation from the telco.

2014-01-09T13:29:29 < karlp> so, what _did_ they put in for new housing?
2014-01-09T13:29:59 < karlp> I haven't lived in aus for years now, but at least here, new housing areas tends to get new and hot stuff for networking, because, why would you do anything else?
2014-01-09T13:30:37 < zyp> over here, adsl is considered to be pretty shit nowadays
2014-01-09T13:32:01 < jpa-> over here, they are removing the ADSL cables and replacing it with nothing
2014-01-09T13:32:30 < jpa-> supposedly replaced with 3G but that works like shit most of the time
2014-01-09T13:32:44 < karlp> "removing adsl" meaning, they're pulling out the copper to the homes? why would they go to the effort of just pulling it out?
2014-01-09T13:33:23 < jpa-> karlp: because it's mostly airwires and they have to pay to the land owners as long as the line is there
2014-01-09T13:33:45 < jpa-> and now that no-one pays for ridicuously expensive landline phones anymore, it doesn't make profit
2014-01-09T13:33:48 < karlp> how does that work?
2014-01-09T13:34:01 < karlp> you have a phone line, and the phone company pays you to have the line htere?
2014-01-09T13:34:09 < karlp> and then you pay them to actually use it?
2014-01-09T13:34:26 < jpa-> nah, i mean the land owners where the line goes through - not the endpoint
2014-01-09T13:34:42 < jpa-> and line maintenance of course costs also
2014-01-09T13:34:49 < karlp> so, leaving a plastic conduit but pulling the copper out makes them not having to pay for it anymore?
2014-01-09T13:35:01 < karlp> stopping maintennance doesns't need you to pull it out :)
2014-01-09T13:35:16 < zyp> wat
2014-01-09T13:35:16 < jpa-> no no, it is telephone poles and cables hanging in the air
2014-01-09T13:35:52 < karlp> oh, ok.
2014-01-09T13:35:57 < karlp> that makes more sense :)
2014-01-09T13:36:14 < qyx_> here they tend to bury optics everywhere they can
2014-01-09T13:36:17 < karlp> you had phone lines in the air?
2014-01-09T13:36:24 < karlp> I can't remember seeing them since I left the states
2014-01-09T13:36:27 < qyx_> even empty conduits
2014-01-09T13:36:29 < jpa-> i bet some pointy haired boss has looked at some 3G coverage map and marketing claims "look this 3G is faster and available everywhere, why do we still provide ADSL?!?"
2014-01-09T13:36:49 < jpa-> karlp: sure.. most power lines are in the air also
2014-01-09T13:37:24 < karlp> we have power in the air out in the countryside, in some places
2014-01-09T13:37:29 < zyp> bunch of that here too, but that's because I live in an old area where they didn't put wires in the ground when it was developed
2014-01-09T13:37:46 < karlp> some heavy debate at the moment actually about the relative costs of high voltage in teh ground vs the air
2014-01-09T13:37:55 < karlp> but all the residential power is in the ground
2014-01-09T13:37:58 < zyp> that was kinda weird to me when I moved south, because even in the rural town in the north I came from, there's nothing of that

2014-01-09T13:45:10 < dongs> zyp: i can, sure
2014-01-09T13:45:16 < baird> Telstra's met to be the the AU Neocon's "Shining Example" of why direct privatisation of public services WERKS... In spite of the fact that they have to constantly give Telstra licences to print money several times a year with bullshit like the no-ADSL-4-U stuff.
2014-01-09T13:45:25 < dongs> just gimme the spec and they'll have them
2014-01-09T13:45:38 < zyp> < dongs> zyp: yea confirmed JST header is provided by them. including crimping stuff.  you'll need to do headers. <- that's do as in provide?

2014-01-09T16:09:55 < Laurenceb> nah got 3 sides down
2014-01-09T16:10:16 < Laurenceb> turns out leaded solder works way better for tinning the pads
2014-01-09T16:11:08 < zyp> I'd guess that's just because there's proper flux in it, while your rohs solder has shitty flux

2014-01-09T17:22:39 < Laurenceb> dry joints somewhere
2014-01-09T17:22:53 < Laurenceb> im going to have to get a stencil just for making one board :-/
2014-01-09T17:23:06 < Laurenceb> these LGA pads are horrible
2014-01-09T17:23:15 < Laurenceb> dunno whats wrong with them
2014-01-09T17:23:22 < Laurenceb> solder wont stick easily at all
2014-01-09T17:24:34 < qyx_> i also had problems with lsm parts
2014-01-09T17:24:42 < qyx_> other things work ok
2014-01-09T17:26:17 < Laurenceb> nope no luck
2014-01-09T17:26:33 < Laurenceb> ive damaged the silkscreen now so i cant flood it evenly with solder
2014-01-09T17:26:39 < Laurenceb> so no point continuing
2014-01-09T17:26:54 < Laurenceb> stencil and reflow oven for next attempt
2014-01-09T17:28:18 < qyx_> tons of rework gel was required
2014-01-09T17:28:32 < Laurenceb> the solder repellant pads are just impossible to work with
2014-01-09T17:30:53 < Laurenceb> dongie: so heres a challenge for you

2014-01-09T17:42:20 < Robint91> I tin both LGA and PCB

2014-01-10T00:39:29 < karlp> probably means I can get protocol decode, that the rigol doesn't have natively
2014-01-10T00:40:10 < Steffanx> Could be useful.
2014-01-10T00:40:14 < UweBonnes> Sigrok now supports  Logic16 also.

2014-01-10T01:27:01 < Steffanx> it really takes that long to get stuff to you from china karlp?
2014-01-10T01:29:29 < Laurenceb_> ive has stuff next day
2014-01-10T01:29:49 < Laurenceb_> but i live right near to a DHL hub

2014-01-10T01:31:48 < Steffanx> dhl..
2014-01-10T01:32:08 < karlp> no, 3-5 weeks seems to be common
2014-01-10T01:32:12 < Steffanx> most people dont use DHL when they order a $10 device :)
2014-01-10T01:32:34 < karlp> but the sellers guaranteed rate, at which point I can ask alibaba for a refund, is "15-60 days"
2014-01-10T01:32:50 < karlp> that's before customs grabs it for ~1 week
2014-01-10T01:33:12 < karlp> I've recently found a way to have them email me when they get a parcel for my address, instead of posting me a snailmail request to send them the invoice
2014-01-10T01:33:17 < karlp> so that should save maybe two days

2014-01-10T02:31:27 < karlp> more features for free on my existing scope? not going to complain
2014-01-10T02:31:51 < BrainDamage> the interfaces still kinda suck atm
2014-01-10T02:31:59 < BrainDamage> but it's promising
2014-01-10T02:32:18 < karlp> at least for the rigol, it can't be _any_ worse than their tethered software
2014-01-10T02:32:33 < karlp> and it might even work in linux, and any protocol decoding is better than none

2014-01-10T07:05:21 < FreezingCold> I find it so weird that a sales place doesn't have an email address though

2014-01-10T07:08:21 < GargantuaSauce> Ottawa, Canada: In 1993, SGS-Thomson purchased the semiconductor activities of Nortel which owned in Ottawa an R&D center and a fab. The fab was closed in 2000, however, a design, R&D centre and sales office is operating in the city.
2014-01-10T07:09:55 < FreezingCold> Not really related, but I love how it's been half a decade since Nortel went under and they're still dealing with the legal issues
2014-01-10T07:11:44 < GargantuaSauce> well they were worth like half a trillion dollars at one point

2014-01-10T08:02:59 < GargantuaSauce> it's a six-layer board and the middle two layers are thermite

2014-01-10T08:05:17 < FreezingCold> Haha, that's Microchip's level.
2014-01-10T08:07:09 < gnomad> FreezingCold: who is going to waste time developing a product on the chance they might get the smackdown?
2014-01-10T08:08:13 < GargantuaSauce> they're damn chunky too
2014-01-10T08:08:22 < gnomad> and it is also more like ST saying... we reserve the right to discontinue this product at any time.
2014-01-10T08:08:23 < GargantuaSauce> .1" headers in a modern product? please
2014-01-10T08:08:25 < FreezingCold> gnomad: I don't even think those kind of EULA are even legal in most countries though. They could stop making the product altogether, but that's the only option
2014-01-10T08:08:53 < gnomad> and it is also a limitation on their liability.
2014-01-10T08:08:58 < FreezingCold> it seems weird they'd even bother saying it
2014-01-10T08:09:07 < gnomad> so there are all sorts of reasons in addition to the stated one
2014-01-10T08:09:12 < FreezingCold> heh
2014-01-10T08:09:29 < gnomad> but it should be obvious, because as we have established, they are selling these things at a loss....
2014-01-10T08:09:43 < FreezingCold> Oh yeah, that's why I said I didn't have plans of abusing it :)
2014-01-10T08:10:27 < gnomad> but if you make something that will be useful to ten people, and sell ten widgets witha discovery board, nobody is really going to give a shit

2014-01-10T08:13:29 < FreezingCold> upgrdman: I wonder if they should have used ethernet instead of USB if they wanted it to be a little closer to real-time

2014-01-10T08:15:09 < GargantuaSauce> the latency would probably end up being higher with ethernet
2014-01-10T08:15:14 < GargantuaSauce> better throughput though
2014-01-10T08:15:21 < FreezingCold> Mhm
2014-01-10T08:17:39 < baird> I met a guy in Longreach (he was on holiday as well), who's involved with designing machinery for handling 450mm silicon wafer tech..
2014-01-10T08:18:16 < gnomad> when people stop buying them
2014-01-10T08:18:24 < gnomad> which is probably never.
2014-01-10T08:18:28 < FreezingCold> GargantuaSauce: I'm 50% sure my math is wrong here, but assuming there's zero overhead with udp (which is totally false), couldn't a 10Gbps line sample up to 100MHz?
2014-01-10T08:19:07 < FreezingCold> assuming you're only sending a 1 or 0 and not a voltage level
2014-01-10T08:19:27 < gnomad> So do you understand how ethernet actually works?
2014-01-10T08:19:41 < gnomad> and how routers work?
2014-01-10T08:20:09 < FreezingCold> and see, that's why I said my math was far off lol
2014-01-10T08:20:35 < FreezingCold> I know ethernet does some weird magnetic thingy for the physical connectors
2014-01-10T08:20:51 < gnomad> that is irrelevant.

2014-01-10T08:54:00 < qyx_> uf azbuka
2014-01-10T08:56:35 < PaulFertser> kW/h is totally meaningless
2014-01-10T08:56:38 < FreezingCold> I assume kW/nanosecond
2014-01-10T08:57:42 < PaulFertser> So when people assume kW is kW/h that's not any better than assuming kW or any other nonsense.
2014-01-10T08:58:49 < PaulFertser> I can't see how using wrong and misleading units can be ok for any text or even a casual conversation.

2014-01-10T09:42:56 < gnomad> kickstarter was a pretty good idea, but I think they misunderestimated how quickly it would be abused.

2014-01-10T09:46:35 < gnomad> failed, in this case, means funded but failed to deliver.
2014-01-10T09:47:18 < gnomad> but is it 5% or 50%
2014-01-10T09:47:20 < gnomad> ?

2014-01-10T12:58:16 < vadmeste> Hello everybody. I tried to compile the STM32 project for my STM32F429 under a gnu/linux distro using my own Makefile. However, the generated bin image is about 5Mb which cannot fit into the board flash. I used gcc-arm-none-eabi-4_7 from launchpad.net/gcc-arm-embedded/ and I activated all needed optimizations that I already know. Any ideas ?
2014-01-10T12:58:55 < qyx_> using some other sample makefile?

2014-01-10T13:02:10 < vadmeste> qyx_: sample projects work and are tiny
2014-01-10T13:07:32 < baird> Can you tell where the bloatage is coming from? Are any object files going into the .bin excessively large? "size *.o" .. Extern-declared structs often do this.
2014-01-10T13:13:06 < vadmeste> baird: it may be the static library STemWin522_4x9i_CM4_OS_GCC.a (4.0 megabytes)
2014-01-10T13:14:12 -!- bsdfox [~h36sa@freebsd/contributor/bobryan] has joined ##stm32
2014-01-10T13:14:34 < zyp> vadmeste, use arm-none-eabi-size to get the relevant sizes
2014-01-10T13:14:51 < zyp> the files are also full of debug info that's not going into the flash
2014-01-10T13:15:09 < baird> Yep, libraries are the other culprit.. Everyone learns to avoid the likes of printf() :)
2014-01-10T13:15:18 < qyx_> but he said the .bin is large
2014-01-10T13:15:27 < qyx_> so i assume that the bin may be wrongly generated
2014-01-10T13:15:48 < zyp> that might be
2014-01-10T13:16:04 < zyp> run the mentioned size tool on the elf file the bin is generated from
2014-01-10T13:16:27 < dongs> lol emwin
2014-01-10T13:16:28 < zyp> text and data goes into flash, bss is only ram
2014-01-10T13:16:29 < baird> size works on just elf?
2014-01-10T13:17:11 < zyp> works on both elf executables, elf objects and archives containing objects
2014-01-10T13:17:35 < zyp> probably works on a couple of other formats too
2014-01-10T13:18:19 < vadmeste> well, I run this, arm-none-eabi-size docea-demo.elf
2014-01-10T13:18:32 < zyp> what's the output?
2014-01-10T13:18:35 < vadmeste>    text    data     bss     dec     hex filename
2014-01-10T13:18:35 < vadmeste> 1205896 4198912  184080 5588888  554798 docea-demo.elf
2014-01-10T13:19:22 < zyp> ok, that's 1.2 megabytes of executable, over 4 megabytes of data and 184k of uninitialized ram
2014-01-10T13:20:05 < zyp> the executable code is not the problem, but both data and bss are going into ram, and you only have 192k of sram (not counting ccm), and that won't fit either way
2014-01-10T13:20:31 < baird> Bloated data segment-- looks like a struct&etc. issue. Hardcoded tables? (..and poor choice of datatype)
2014-01-10T13:21:03 < zyp> probably lots of resources that you forgot to declare const
2014-01-10T13:21:20 < vadmeste> baird: I think it is due to some images in the STM32F429 demo
2014-01-10T13:21:30 < baird> If it's something like a BMP file for displaying on an LCD, using another encoding. :)
2014-01-10T13:21:37 < vadmeste> wait, actually I am compiling code from stm32 website
2014-01-10T13:21:46 < zyp> I assume what makes up most of the text segment is also a bunch of const data

2014-01-11T02:46:04 < karlp> dongs, mr tv, is there really anything I need to know about hdmi versions if I'm buying a tv?
2014-01-11T02:47:15 < dongs> probably not, if its anything recent it'll  be fine
2014-01-11T02:47:41 < dongs> there's a new hdcp version but i think even that's a few years old now so anything should uspport it.
2014-01-11T02:48:08 < zyp> does hdcp matter much?
2014-01-11T02:48:29 < karlp> what does this mean: "4x HDMI (1 arc)" ?
2014-01-11T02:48:36 < karlp> (the arc bit)
2014-01-11T02:48:39 < zyp> audio return channel
2014-01-11T02:48:44 < zyp> i.e. audio out
2014-01-11T02:48:52 < [7]> that can indeed be rather useful
2014-01-11T02:49:10 < [7]> HDMI CEC as well
2014-01-11T02:49:18 < zyp> for when you want to pipe the audio from the built-in tuner into a receiver or something like that
2014-01-11T02:49:19 < karlp> ah, I guess that could be, even more so if I had a receiver :)

2014-01-11T02:57:36 < dongs> they should just move all TVs to displayport

2014-01-11T02:58:22 < karlp> what's so cool about displayport again?
2014-01-11T02:58:53 < zyp> more bandwidth
2014-01-11T03:00:16 < zyp> a bunch of the new monitors that are coming out nowadays are displayport only
2014-01-11T03:00:36 < zyp> quite naturally, since DVI can't handle 4k
2014-01-11T03:00:51 < karlp> haven't seen it on _any_ of the tvsIve been looking at tonight.
2014-01-11T03:00:59 < karlp> but I'm only looking at 1920x1080 stuff
2014-01-11T03:01:06 < zyp> I didn't say TVs, I said monitors
2014-01-11T03:01:15 < karlp> yeah, I heard, but dongs said it should be on tvs :)
2014-01-11T03:01:46 < zyp> that's probably not going to happen
2014-01-11T03:13:47 < zyp> displayport's aim was to replace DVI, and that's happening now
2014-01-11T03:14:30 < karlp> and tv's only have vga or hdmi for input from comptuers though that I'm seeing
2014-01-11T03:14:50 < zyp> yes, I've never seen a TV with a DVI port :)
2014-01-11T03:15:22 < zyp> that said, HDMI and DVI are both TMDS, so originally they were pretty much the same
2014-01-11T03:15:56 < zyp> DVI jacked up the bandwidth by adding another three data lines, while HDMI jacked up the bitrate
2014-01-11T03:18:22 < dongs> doesnt DVI need clock and data shits
2014-01-11T03:18:34 < dongs> where as displayport is just differential lane with embeded clock
2014-01-11T03:18:39 < zyp> yes
2014-01-11T03:18:58 < zyp> HDMI and single-link DVI is one clock lane and three data lanes
2014-01-11T03:19:03 < dongs> yeah
2014-01-11T03:19:08 < zyp> dual-link DVI has clock and six data lanes
2014-01-11T03:19:20 < zyp> hmm
2014-01-11T03:19:28 < dongs> haha apparently there's hdcp for dispplayport
2014-01-11T03:19:33 < dongs> aes128 DPCP
2014-01-11T03:20:07 < zyp> the DP spec actually has a definition of dual-mode sources, i.e. devices that can output TMDS through the displayport connector
2014-01-11T03:20:14 < dongs> right
2014-01-11T03:20:16 < dongs> the DP++ shit?
2014-01-11T03:20:21 < zyp> yeah
2014-01-11T03:20:22 < dongs> thats why there's $1 adapters
2014-01-11T03:20:25 < dongs> to go from dp to hdmi/dvi
2014-01-11T03:20:28 < dongs> but not the othe way around
2014-01-11T03:20:31 < zyp> yes
2014-01-11T03:20:34 < dongs> cuz its just straight through cable
2014-01-11T03:20:50 < zyp> my macbook does that
2014-01-11T03:21:43 < zyp> I have a cable that's just a minidp plug in one end and a hdmi plug in the other, so it doesn't even need an adapter

2014-01-11T03:22:36 < gxti> HDMI (1.0 anyway) is a direct extension of DVI, so it doesn't require extra support in the source either
2014-01-11T03:23:12 < gxti> which is odd because HDMI went on to be mainly a TV thing and DP which is unrelated is now the monitor thing
2014-01-11T03:23:27 < dongs> hah hdmi 4.0 released september 2013
2014-01-11T03:23:31 < dongs> 14gbit bandwidth
2014-01-11T03:23:36 < dongs> didnt displayport do that years ago

2014-01-11T03:34:14 < gxti> at 4k
2014-01-11T03:34:18 < dongs> haha i see
2014-01-11T03:34:19 < gxti> which is the point i guess
2014-01-11T03:34:20 < dongs> in specs
2014-01-11T03:34:29 < dongs> holy fucking fail
2014-01-11T03:34:31 < dongs> its because of FUCKING HDMI
2014-01-11T03:34:47 < gxti> right now i have a 1920x1200 IPS and a 1920x1080 144hz, when i got the latter my eyes were bleeding because i forgot how ugly TN is
2014-01-11T03:35:07 < gxti> 30fps TN would make me kill myself
2014-01-11T03:35:25 < zyp> yeah
2014-01-11T03:35:35 < zyp> the 32" one is IGZO IPS
2014-01-11T03:36:31 < zyp> is the 144Hz one an Asus VG248QE?
2014-01-11T03:36:48 < gxti> yeah
2014-01-11T03:37:03 < zyp> a friend got a couple of those in portrait mode
2014-01-11T03:37:22 < gxti> i mean you can get used to any panel really, but next to IPS it looks like trash color wise
2014-01-11T03:37:29 < karlp> bloody regional product codes, only mention of this product number is in danish finnish and norwegian
2014-01-11T03:37:33 < zyp> yes, not to mention the angles
2014-01-11T03:37:53 < zyp> which are especially horrible when you have it in portrait mode
2014-01-11T03:38:03 < dongs> heh
2014-01-11T03:38:45 < dongs> zyp, 10bit shit is usually IPS right?
2014-01-11T03:38:53 < zyp> dunno, probably
2014-01-11T03:39:02 < dongs> http://www.panelook.com/M270QAN01.0_AUO_27.0_LCM_overview_20793.html hm this shit says a-Si TFT
2014-01-11T03:39:06 < dongs> is that TN? or wat
2014-01-11T03:39:18 < zyp> TFT is like all color lcds :p
2014-01-11T03:40:16 < dongs> dual dp, it will split half screen
2014-01-11T03:40:17 < dongs> hmm
2014-01-11T03:40:26 < zyp> a-Si apparently means amorphous silicon
2014-01-11T03:42:02 < dongs> ha that panel has separate backlight connector
2014-01-11T03:42:10 < dongs> 22leds per string
2014-01-11T03:42:12 < zyp> it says AHVA
2014-01-11T03:42:21 < dongs> 92V for backlight??
2014-01-11T03:42:55 < dongs> no, 79.2V
2014-01-11T03:42:57 < dongs> still
2014-01-11T03:42:58 < dongs> wtf
2014-01-11T03:43:02 < dongs> what driver does this? :)
2014-01-11T03:43:25 < zyp> ah, AHVA is apparently «AUO's version of IPS»
2014-01-11T03:43:28 < zyp> so that's an IPS panel
2014-01-11T03:43:30 < dongs> oyh really
2014-01-11T03:43:31 < dongs> cool
2014-01-11T03:43:46 < dongs> maybe i should get it
2014-01-11T03:44:10 < zyp> how much is it?
2014-01-11T03:45:47 < dongs> MOQ of 10 pcs so doesnt matter
2014-01-11T03:46:12 < Laurenceb_> http://www.indiegogo.com/projects/tellspec-what-s-in-your-food
2014-01-11T03:46:14 < zyp> 10 is not that many
2014-01-11T03:46:15 < Laurenceb_> interesting
2014-01-11T03:46:40 < dongs> haha panealook shows skype
2014-01-11T03:46:45 < dongs> ill add that troll up and see how much
2014-01-11T03:46:50 < Laurenceb_> 2) an algorithm that exists in the cloud;

2014-01-11T03:47:31 < gxti> Laurenceb_: you mean the idea of a tiny handheld device that can sniff out molecules didn't stop you first?
2014-01-11T03:47:37 < Laurenceb_> my job is making spectrometers
2014-01-11T03:47:45 < Laurenceb_> this doesnt look sane
2014-01-11T03:47:50 < gxti> duhhhhhhh
2014-01-11T03:47:54 < Laurenceb_> i thought of the idea myself and ruled it out
2014-01-11T03:48:07 < dongs> you linked to something on dickstarter
2014-01-11T03:48:11 < dongs> and you expect it to be legit???
2014-01-11T03:48:15 < Laurenceb_> lol
2014-01-11T03:49:00 < Laurenceb_> maybe if they used a high power pulsed laser to vapourize the food....
2014-01-11T03:49:32 < Laurenceb_> http://d2oadd98wnjs7n.cloudfront.net/file_attachments/86992/files/20130920172918-WithoutLogo_2.jpg?1379723358
2014-01-11T03:49:37 < Laurenceb_> L.O.L.
2014-01-11T03:50:28 < dongs> Laurenceb_: you should be on their advisor board
2014-01-11T03:50:31 < gxti> http://drop-kicker.com/2013/10/tellspec-food-analyzer/ <- someone smarter than Laurenceb_
2014-01-11T03:50:39 < Laurenceb_> heh
2014-01-11T03:50:43 < gxti> i especially like the part where there's no room for a PCB in the housing
2014-01-11T03:52:23 < Laurenceb_> lol
2014-01-11T03:52:38 < Laurenceb_> "someone smarter than Laurenceb_" hey i said it was fake
2014-01-11T03:53:08 < Laurenceb_> heres how it could work:
2014-01-11T03:53:37 < Laurenceb_> shark -> big L.A.S.E.R. -> vaporize the food -> chemical "nose"
2014-01-11T03:55:15 < dongs> holy shit
2014-01-11T03:55:17 < dongs> they got 380k
2014-01-11T03:55:25 < dongs> i just clicked on the indieblog campaign page
2014-01-11T03:55:50 < karlp> hehe, and it was flexi funding too, so they were always goign to get it
2014-01-11T03:56:02 < karlp> crazy woo medicine lovers love to spend money
2014-01-11T03:58:14 < gxti> oh noooo there's MOLECULES in my food
2014-01-11T03:59:46 < dongs> http://drop-kicker.com/2013/10/tellspec-food-analyzer/#comment-4765 roofl
2014-01-11T04:07:53 < dongs> Trivialities like R&D and integration are why it’s puzzling that they have (as of the last time I checked the company website) no engineering staff. Industrial designers, statisticians, business people, food photographers, all there except for anybody that can actually make a functioning device out of parts.
2014-01-11T04:07:58 < dongs> haha
2014-01-11T04:08:01 < dongs> food photographers
2014-01-11T04:08:03 < dongs> isn't that like =~ bloggers
2014-01-11T04:09:07 < gxti> heh, no
2014-01-11T04:09:17 < Laurenceb_> you know its fake when the employees have the skillz to fake it but not to make it
2014-01-11T04:09:19 < dongs> more levels below?
2014-01-11T04:10:12 < gxti> they're quasi-marketing people so pretty much scum
2014-01-11T04:12:24 < Laurenceb_> but but  but

2014-01-11T04:14:18 < Laurenceb_> "Raman (600 to 1600cm^-1)" <- wow a magic massively tunable semiconductor laser
2014-01-11T04:14:25 < Laurenceb_> they must have invented ti
2014-01-11T04:14:57 < englishman> mmm, ramen
2014-01-11T04:15:33 < Laurenceb_> ram man,  worse than goat man
2014-01-11T04:16:07 < Laurenceb_> omg they made a nanochip
2014-01-11T04:17:32 < dongs> is that how they manage to fit it all inside that molded enclosuore?
2014-01-11T04:17:42 < Laurenceb_> clearly

2014-01-11T04:46:54 < dongs> i failed calculus 101 twice
2014-01-11T04:46:56 < dongs> then said fuckit.
2014-01-11T04:47:09 < dongs> might have been only once
2014-01-11T04:47:14 < dongs> i dont think i bothered taking it again
2014-01-11T04:47:16 < qyx_> keep your exitation level low, it's just an arm

2014-01-11T04:49:55 < gxti> no, pci-e ssd. but it's missing a few things
2014-01-11T04:49:59 < dongs> what is that shit, some fibrechannel trash?
2014-01-11T04:49:59 < dongs> ah
2014-01-11T04:50:02 < dongs> ssd, right
2014-01-11T04:50:04 < dongs> didnt think of that
2014-01-11T04:50:12 < dongs> i think its missing the actual SSD part.
2014-01-11T04:50:20 < dongs> 2012/13
2014-01-11T04:50:22 < dongs> is that from CES
2014-01-11T04:50:32 < dongs> why does it need pcie-4x
2014-01-11T04:50:39 < dongs> does it move shit faster than 1.5gb/sec or osmething
2014-01-11T04:51:03 < gxti> that's not that difficult for a SSD
2014-01-11T04:51:57 < FreezingCold> dongs: I more or less dropped out once
2014-01-11T04:53:02 < gxti> what held you back? you should have tried harder.
2014-01-11T04:53:31 < dongs> i was paying with my own money instead of leeching from the government like a typical american student, so decision to quit was super easy.
2014-01-11T04:55:52 < englishman> paying for university is like buy-high-sell-low stock market tactics

2014-01-11T16:15:03 < zyp> oh, by the way, do any of you have any thoughts about how to format configuration data to be stored on flash in a future-proof way?
2014-01-11T16:15:30 < jpa-> inifile is not a bad format
2014-01-11T16:15:40 < dongie> whats a'futureproof way'?
2014-01-11T16:15:46 < dongie> you wanna be able to read old config without trashing sdtuff?
2014-01-11T16:16:13 < zyp> like, when a new firmware comes out that adds more configuration options, I want to keep the options set in the old one
2014-01-11T16:16:37 < gnomad> will an associated list work?  or do you need something more complex?
2014-01-11T16:17:03 < zyp> I'm mostly thinking in a general sense now
2014-01-11T16:17:03 < jpa-> zyp: one way is just to add options to the end of an array
2014-01-11T16:17:58 < zyp> yes, as long as you have a linear progression of versions
2014-01-11T16:18:09 < jpa-> i do something similar here.. struct parameters_t just contains the stuff i want to save, and if the flash contains less stuff the rest is initialized to default values   https://svn.kapsi.fi/jpa/sphere2/src_common/parameters.h
2014-01-11T16:18:32 < jpa-> yeah, or are willing to leave dummy entries in between
2014-01-11T16:18:57 < dongie> .ini
2014-01-11T16:19:00 < dongie> done
2014-01-11T16:19:05 < dongie> or use nanopb and credit jpa-
2014-01-11T16:19:22 < jpa-> .ini works but requires parsing
2014-01-11T16:19:27 < zyp> well, part of why I asked was because I was wondering whether the pb format would be suited
2014-01-11T16:19:44 < jpa-> sure it is suited, though maybe an overkill in some cases
2014-01-11T16:19:50 < zyp> .ini is obviously unsuited since I don't want to deal with ascii and shit
2014-01-11T16:20:18 < jpa-> with pb, you need to have the RAM to parse the settings to.. if you do a struct, you can just read it from the flash directly
2014-01-11T16:20:25 < zyp> it'll be stored in a flash page of an mcu, not in a file that's going to be opened and edited by hand
2014-01-11T16:20:35 < zyp> yeah, that's true
2014-01-11T16:21:22 < jpa-> though if you have a program for editing configurations, with pb you could just pass the whole stuff between the PC program and flash
2014-01-11T16:22:12 < zyp> I was thinking about doing a layered approach, having one storage layer that does checksumming, versioning and wear levelling, and then having a formatting layer on top of that
2014-01-11T16:22:29 < jpa-> makes sense
2014-01-11T16:23:00 < zyp> wear levelling and versioning in the sense that I grab an array of pages, store a header with version and checksum in each, and use the newest valid one I can find
2014-01-11T16:23:27 < jpa-> though how large area of flash are you going to use (how much data do you have) if you are going to wear level? isn't a single flash page already like 16kB?
2014-01-11T16:23:46 < jpa-> i guess you can clear it once and update the config many times by using it in a log-structure
2014-01-11T16:24:59 < zyp> pages are 2k on F1/F3
2014-01-11T16:25:51 < jpa-> ah
2014-01-11T16:26:09 < zyp> didn't think about dividing pages, but obviously that can also be done
2014-01-11T16:26:31 < zyp> so as long as I have at least two pages to config, I'll never have to erase the latest config
2014-01-11T16:28:00 < zyp> then I'll just search through the pages on startup, finding the one with the highest version number and using that
2014-01-11T16:28:12 < zyp> and when I'm storing a new one, I'll just increment the version
2014-01-11T16:29:42 < dongie> wut
2014-01-11T16:29:52 < dongie> you have to erase the old page to icnrement version anyway.

2014-01-11T16:31:17 -!- fbs is now known as fubs2
2014-01-11T16:31:28 < jpa-> the need for wear level depends completely on how often the settings are updated

2014-01-11T16:31:33 -!- fubs2 is now known as fubs

2014-01-11T17:14:00 < PaulFertser> dongs: regarding avr, you can't really brick an IC by using wrong fuses. When flashing over SPI you can't disable SPI. Maximum you can do is to set it to use external clock, but you can recover by providing any clock to XTAL1 pin.
2014-01-11T17:15:08 < dongie> um,
2014-01-11T17:15:14 < dongie> PaulFertser: you're very much wrong
2014-01-11T17:15:17 < dongie> you CAN disable SPI over SPI
2014-01-11T17:15:21 < dongie> as well as RSTDIS
2014-01-11T17:15:31 < dongie> both of which will fuck it over and require parallel progrtamming
2014-01-11T17:15:53 < PaulFertser> dongie: tell me the exact part and I'll prove you can't disable spi over spi on it.
2014-01-11T17:16:03 < dongie> PaulFertser: anything, 328, 32u4, etc.

2014-01-11T17:22:18 < PaulFertser> Eclipse project files suck, but that's not a fault of a toolchain.

2014-01-11T17:25:33 < dongie> downloading anyway.

2014-01-11T17:28:30 < PaulFertser> Indeed
2014-01-11T17:28:43 < PaulFertser> On those parts that support that feature, yes, certainly a nasty one.
2014-01-11T17:29:02 < PaulFertser> btw, i.MX25 I use has real fuses inside, no way to change them at all after flashed once.
2014-01-11T17:29:21 < dongie> i.mx sucks for different reasons :)
2014-01-11T17:30:48 < dongie> PaulFertser: the problem is not the fact that you can't unset the fuses
2014-01-11T17:30:52 < dongie> the problem is they exist in the first place
2014-01-11T17:31:22 < dongie> clock control should *never* be something fuse based.
2014-01-11T17:31:28 < dongie> even china fixed that when tehy  cloned mega8
2014-01-11T17:31:54 < dongie> i can't think of a single usecase for it being decided by unchangeable fuses.
2014-01-11T17:32:03 < dongie> lets say external crystal gets damaged, your board stops working
2014-01-11T17:32:12 < dongie> where if you could fallback to intrc, it continues working, perhaps at reduced performance
2014-01-11T17:32:25 < dongie> or if you code it carefeully, at same performance, while user is notified to replace shit

2014-01-14T04:19:35 < dongs> what do you mean?
2014-01-14T04:19:37 < gxti> yes your crap has to be recertified even if you're using a module
2014-01-14T04:19:39 < dongs> it would be the only component really
2014-01-14T04:19:43 < dongs> gxti: really?
2014-01-14T04:19:53 < dongs> since i'd just run some boring trash on 8051 thats on there
2014-01-14T04:19:58 < gxti> but it's much less traumatic because hopefully they didn't fuck it up too bad
2014-01-14T04:22:02 < dongs> gxti: are you sure it needs re-certify even when module?

2014-01-14T04:22:29 < dongs> that you don't need to certify them again

2014-01-14T16:29:11 < dongie> apparently shit like LM1117 etc also have it
2014-01-14T16:30:03 < jpa-> so what's wrong with the 2 diodes 1 regulator approach?

2014-01-14T16:35:03 < dongie> yeah its fine

2014-01-14T18:09:27 < zyp> is that a US thing?
2014-01-14T18:09:52 < zyp> because most thermostats in Norway operates directly on 230V
2014-01-14T18:10:03 < karlp> nest is a tech darling for being apple like

2014-01-14T18:11:04 < Steffanx> i think 24V is common here as well zyp
2014-01-14T18:11:13 < Steffanx> Im pretty sure its not powered by 230
2014-01-14T18:11:35 < karlp> despite half the world being completely fine with a thermostat just having a temperature, or even just a dial from 1-10 or something
2014-01-14T18:12:10 < karlp> hell, I don't even have a thermostat, I just have a flow control dial on two separate hot water radiators
2014-01-14T18:12:13 < Steffanx> i only read the interesting posts on your blog karlp :)
2014-01-14T18:12:21 < qyx_> we also use 230V thermostats

2014-01-14T18:19:39 < karlp> I haven't gotten one yet,
2014-01-14T18:19:42 < karlp> I had one all picked out,
2014-01-14T18:19:54 < karlp> went down to get it, and the girlfriend asked why the credits flickered so much
2014-01-14T18:20:09 < karlp> I hadn't noticed it, but when she had pointed it out, it was visible on a bunch of others
2014-01-14T18:20:20 < dongie> credits?
2014-01-14T18:20:24 < karlp> dude int eh store said it was the refresh rate being 50hz, intstead of 100 or 200
2014-01-14T18:20:32 < karlp> dongie: rolling text credits at the end of a movie
2014-01-14T18:20:41 < karlp> just happened to be finishing their demo movie when we were there
2014-01-14T18:20:53 < zyp> sounds like jitter due to framerate conversion
2014-01-14T18:21:08 < karlp> but we found some different tvs that only claimed to be 50 as well, and some were good, some were bad.
2014-01-14T18:21:39 < karlp> so, going to look at a couple of others on the list tomorrow
2014-01-14T18:21:55 < karlp> then maybe just buy the first one anyway :)
2014-01-14T18:21:58 < RaYmAn> The tvs with the fake '100hz'+ tend to look worse because they interpolate so much - so stay clear or CNR, and whatever else they call it
2014-01-14T18:22:41 < karlp> well, I didn't go and exhaustively compare what they claimed and whether they had jittery scrolling text or not, but probably a good 1/3 tvs in the store all had shitty jittery text when it moved,
2014-01-14T18:22:45 < karlp> others were all fine
2014-01-14T18:22:48 < zyp> are you sure the flickering was not a problem with the signal fed to the tv?
2014-01-14T18:22:53 < karlp> could have been :)
2014-01-14T18:23:01 < karlp> dude in the store claimed otherwise, but hard to say,
2014-01-14T18:23:14 < zyp> that's probably just marketing bullshit :p
2014-01-14T18:23:16 < karlp> store salesmen aren't exactly high on my list of trusted authority figures
2014-01-14T18:23:19 < karlp> indeed :)
2014-01-14T18:23:53 < karlp> he was trying to get me to spend more by telling me that sports would all look crap if I didn't hve the higher rate tvs,
2014-01-14T18:24:02 < karlp> but a) that would need higher rate broadcasts
2014-01-14T18:24:06 < karlp> and b) I'd have to care about sports

2014-01-14T20:47:54 < trepidaciousMBR> Thorn: How do you mean?
2014-01-14T20:50:41 < Thorn> my system controls several ovens (basically a distributed thermostat) but there's a total current limit for the ovens

2014-01-14T22:12:45 < karlp> heh, one of these usb hubs with power switches on them, power switch is off,
2014-01-14T22:13:07 < karlp> but plugging in this lm4f "launchpad" board still enumerates usb...
2014-01-14T22:14:18 < Thorn> maybe hub power is only used to power attached devices and the hub itself is powered from the host

2014-01-14T22:15:15 < karlp> (because it's getting power from elsewhere)

2014-01-14T22:51:12 < karlp> I could pay more, but I still wouldn't know whether it did what I wanted until I'd bought it
2014-01-14T22:51:52 < karlp> I guess it technically is cutting the _power_
2014-01-14T22:53:35 < PaulFertser> Is f303's USB different from f103 in any noticeable way? I'm trying to run cdcacm example from libopencm3-examples and echo doesn't really work unless I add a dummy ep write right after the actual write.

2014-01-15T02:52:44 < gnomad> From what I've read, later releases of Opera are quite impressive.
2014-01-15T02:53:20 < GargantuaSauce> i use it alongside chromium
2014-01-15T02:53:49 < GargantuaSauce> opera for volume, hundreds of tabs without using obscene amounts of memory, chromium for flashy and googly things
2014-01-15T02:54:28 < gnomad> IIRC, low resource usage is one of the big advantages of opera
2014-01-15T02:54:32 < GargantuaSauce> yup
2014-01-15T02:55:15 < gnomad> which would explain why it is more popular in countries more likely to have older computers
2014-01-15T02:55:21 < GargantuaSauce> i suspect they're going to throw away that advantage with the transition to webkit
2014-01-15T02:55:31 < gnomad> heh... was just going to ask you about that.
2014-01-15T02:55:41 < GargantuaSauce> so i am not sure what i'm going to do when that version is the main release
2014-01-15T02:55:47 < gnomad> wasn't that supposed to happen last year?
2014-01-15T02:56:10 < gnomad> oh, so the webkit engine hasn't made it into the main release yet?

2014-01-15T14:24:05 < dongie> maybe ill throw bma280 on there too
2014-01-15T14:25:21 < dongie> i might need a 2:4 or 3:8 decoder for all the chipseelects
2014-01-15T14:25:27 < dongie> i guess 2:4 is enough
2014-01-15T14:25:37 < Robint91> dongie, everything SPI?
2014-01-15T14:25:39 < dongie> lets see how small those can get

2014-01-15T14:30:28 < dongie> i'd need one w/enable
2014-01-15T14:30:39 < dongie> hm or not
2014-01-15T14:30:41 < Robint91> dongie, so MAX21000 + LSM303DLHC seems a good combo
2014-01-15T14:30:43 < dongie> just select at least something
2014-01-15T14:30:52 < dongie> not DLHC

2014-01-15T14:32:05 < legath_> hi all
2014-01-15T14:32:24 < Steffanx> Hello there.
2014-01-15T14:32:41 < legath_> are anybody know about stm32 simulator?
2014-01-15T14:32:51 < dongie> like what
2014-01-15T14:33:04 < dongie> you can simulate cortex-m with qemu
2014-01-15T14:33:14 < legath_> but only kernel..
2014-01-15T14:33:14 < dongie> and you can write some peripherals if you want, since its opensores.
2014-01-15T14:33:30 < legath_> i try to find complete solution
2014-01-15T14:33:36 < Robint91> dongie, the BMA280 has better specs as the ST part
2014-01-15T14:33:41 < dongie> Robint91: im aware
2014-01-15T14:34:00 < dongie> it might be BMA + hmc5983
2014-01-15T14:34:10 < dongie> since 5983 is whats inside ST anyway.
2014-01-15T14:34:37 < legath_> do you speak about accel?
2014-01-15T14:34:52 < Robint91> legath_, ACCEL is ST
2014-01-15T14:34:54 < dongie> legath_: yes, i stopped talking to you since y ou dont like my solution
2014-01-15T14:35:03 < dongie> about stm32 emulator.
2014-01-15T14:35:03 < Robint91> but the mag part is honeywell
2014-01-15T14:35:44 < Steffanx> i've never heard of a "complete solution" legath_
2014-01-15T14:35:51 < Steffanx> i wonder if there is one
2014-01-15T14:35:56 < dongie> Steffanx: keil has some peripheral emulation, i think :)
2014-01-15T14:35:59 < dongie> inever used it tho
2014-01-15T14:36:06 < Steffanx> of course, keil. :P
2014-01-15T14:36:15 < dongie> i duno if they just emulate cortex peripherals or also do some STM-specific stuffs.
2014-01-15T14:36:28 < Steffanx> ( they just use qemu :P )
2014-01-15T14:37:38 < dongie> hm
2014-01-15T14:37:44 < dongie> shit w/enable is 16pins
2014-01-15T14:37:44 < dongie> lame
2014-01-15T14:37:47 < dongie> and dualsupply etc.
2014-01-15T14:37:48 < legath_> i have found STM32-MAT/TARGET but i do not have MATLAB :)
2014-01-15T14:38:16 < Steffanx> That's to run mathlab crap on an stm32 iirc
2014-01-15T14:38:26 < dongie> Available for 3 toolchains:
2014-01-15T14:38:27 < dongie> Atollic: TrueSTUDIO

2014-01-15T14:38:43 < Steffanx> Atollic is GCC not?
2014-01-15T14:38:48 < dongie> but payware

2014-01-15T21:23:53 < HD_Mouse> i'm working with an stm32 in slave mode running at 72 MHz, and an SPI master running at 16 MHz, and for some reason, bytes seem to be dropped during transmissions to the slave
2014-01-15T21:24:28 < HD_Mouse> problem seems to be solved when I drop the master to 3 Mhz, but that seems unreasonably slow for a master to run at
2014-01-15T21:24:50 < zyp> sounds like you're not processing interrupts fast enough, or something like that
2014-01-15T21:25:16 < zyp> considered using DMA?
2014-01-15T21:25:52 < HD_Mouse> http://pastebin.com/SKmeDQdj
2014-01-15T21:26:12 < HD_Mouse> my ISRs aren't that complicated
2014-01-15T21:26:17 < HD_Mouse> and i can't really see any way of speeding them up
2014-01-15T21:26:28 < fbs> dma helps
2014-01-15T21:26:37 < HD_Mouse> though i could see myself just missing something
2014-01-15T21:27:31 < fbs> why do you have a txe interrupt?
2014-01-15T21:27:53 < HD_Mouse> eh, i was just debugging and thought i'd turn that on to see if it helped
2014-01-15T21:28:07 < fbs> not sure about spi_ovr_isr
2014-01-15T21:28:46 < fbs> volatile uint32_t tmp = SPI1->DR; might be better, i assume your compiler throws that code out with optimalisations
2014-01-15T21:29:13 < zyp> HD_Mouse, are you building with optimizations?
2014-01-15T21:29:18 < zyp> which stm32 variant is this?
2014-01-15T21:29:39 < HD_Mouse> stm32f3
2014-01-15T21:30:25 < HD_Mouse> we have the -O0 flag
2014-01-15T21:30:35 < zyp> ok, then it's natural
2014-01-15T21:31:12 < zyp> 16MHz means 2MB/s, i.e. 2M interrupts per second, which means you have 36 cycles to handle each
2014-01-15T21:31:59 < HD_Mouse> i'm not doing terribly much in the ISR..?
2014-01-15T21:32:20 < zyp> and 36 cycles of unoptimized code is not much, especially not considering interrupt entry/exit will consume a bunch
2014-01-15T21:32:48 < zyp> try -O2, the difference is huge
2014-01-15T21:33:06 < HD_Mouse> sure, give me a minute
2014-01-15T21:33:28 < zyp> but you should really consider DMA instead
2014-01-15T21:34:32 < HD_Mouse> yeah, i use it for some other projects..
2014-01-15T21:34:39 < HD_Mouse> but the purpose of this one was extremely simple
2014-01-15T21:34:45 < HD_Mouse> thought i'd try doing it pure interrupt style instead
2014-01-15T21:37:02 < HD_Mouse> cool, adding in the optimizations seemed to fix the problem
2014-01-15T21:37:04 < HD_Mouse> thanks guys
2014-01-15T21:40:54 < fbs>  is your ovr handler now empty?
2014-01-15T21:44:41 < HD_Mouse> hah, the whole function got optimized out
2014-01-15T21:44:51 < HD_Mouse> good call

2014-01-16T04:51:49 < dongie> was there anything of value?
2014-01-16T04:54:17 < baird> Probably an attempt to get card & personal details..
2014-01-16T04:55:33 < dongie> what kinda tool posts card details on a forum?
2014-01-16T04:55:56 < baird> Back in the late 1980s, was it TDK that discovered that a Chinese operation had cloned its entire business organization?

2014-01-16T13:56:31 < karlp> yeah, I haven't looked at the MTB stuff,

2014-01-16T13:57:40 < zyp> the lack of thumb2 instructions in v6m-disassembly is pretty noticeable, btw

2014-01-16T13:58:13 < karlp> that, and my own lack of ability to count to 14 in an enum and using the wrong values
2014-01-16T13:58:26 < zyp> heh
2014-01-16T13:58:38 < karlp> what do you mean by lack of thumb2?
2014-01-16T13:59:20 < zyp> m0 is v6m, only thumb1 instructions
2014-01-16T13:59:43 < karlp> right, oh, you recgonise thumb2 by sight in dissassembly?
2014-01-16T13:59:54 < karlp> how crap is the nordic firmware if you're looking at dissassembly that much?
2014-01-16T14:00:05 < zyp> I'm not, it just came to mind :)

2014-01-16T19:39:58 < HD_Mouse> so according to the logic analyzer, i seem to be losing bits over spi during a DMA transfer..
2014-01-16T19:40:17 < jpa-> bits or bytes?
2014-01-16T19:40:27 < HD_Mouse> usually just 1-4 bytes
2014-01-16T19:40:41 < jpa-> but always complete bytes?
2014-01-16T19:40:51 < HD_Mouse> the first couple of bytes seem to go over fine, but then one will just be dropped and the rest of the transmission is corrupted
2014-01-16T19:40:54 < HD_Mouse> oh sorry, typo
2014-01-16T19:40:57 < HD_Mouse> 1-4 bits*
2014-01-16T19:41:29 < jpa-> does this happen on receiving SPI to STM32 or on transmitting from STM32?
2014-01-16T19:41:38 < HD_Mouse> transmitting from an stm32
2014-01-16T19:41:57 < jpa-> humm.. sounds pretty strange
2014-01-16T19:42:20 < jpa-> only time i've seen bit-level errors on transmission was when fooling with SPI baud rate / mode registers when SPI was active
2014-01-16T19:43:32 < HD_Mouse> hm, definitely not doing any of that..
2014-01-16T19:44:04 < jpa-> your DMA channel is triggered by the SPI TXE signal and only that, right?

2014-01-16T19:44:29 < HD_Mouse> yes
2014-01-16T19:44:43 < jpa-> (if this is F1 or L1, better make sure that no other peripheral on that channel is giving pulses)
2014-01-16T19:44:54 < HD_Mouse> though i am enabling it in the SPI RXNE isr if that matters
2014-01-16T19:45:04 < HD_Mouse> i have the stm32 waiting for a specific command byte
2014-01-16T19:45:17 < HD_Mouse> then after it receives that, will enable dma to transmit certain bytes
2014-01-16T19:45:23 < HD_Mouse> a certain number*
2014-01-16T19:46:33 < jpa-> is this spi slave or master?
2014-01-16T19:46:46 < HD_Mouse> the slave is the one waiting for the command byte
2014-01-16T19:47:24 < HD_Mouse> master sends the command byte, waits ~20us then sends 160 bytes, to receive the dma transferred bytes
2014-01-16T19:47:37 < fbs> heh
2014-01-16T19:48:03 < jpa-> the slave being too slow would explain extra garbage bits, but not dropping out..
2014-01-16T19:48:04 < HD_Mouse> ?
2014-01-16T19:48:32 < HD_Mouse> the stm32 is running at 72 Mhz, and the master is at 16 Mhz.. shouldn't be an issue
2014-01-16T19:48:38 < jpa-> yeah
2014-01-16T19:49:13 < jpa-> i wonder if the RX overflow condition which will occur has anything to do with it..
2014-01-16T19:49:52 < HD_Mouse> hmm..
2014-01-16T19:49:52 < jpa-> will/may
2014-01-16T19:50:00 < HD_Mouse> my overrun isr is pretty simple
2014-01-16T19:50:02 < jpa-> depending on if your RXNE interrupt keeps reading the bytes
2014-01-16T19:50:38 < HD_Mouse>     (volatile uint32_t) SPI1->DR;
2014-01-16T19:50:39 < HD_Mouse>     (volatile uint32_t) SPI1->SR;
2014-01-16T19:50:49 < HD_Mouse> that's all that's in my overrun isr

2014-01-16T19:51:50 < jpa-> i would try to replace the DMA stuff with a simple loop that sends the bytes, to subdivide the problem space
2014-01-16T19:52:43 < HD_Mouse> sounds good, i'll give it a try

2014-01-17T13:39:48 < dongie> where stm32j isnt
2014-01-17T13:39:56 < karlp> it's been available for f4 disco for a while now

2014-01-17T13:40:32 < Laurenceb> visual basic
2014-01-17T13:40:52 < Steffanx> but STM32J has built-in stuff to execute the java stuff not?
2014-01-17T13:41:08 < Steffanx> note to self: use the word "stuff" more often
2014-01-17T13:42:17 < dongie> dicktrace "fixed" t he problem of thier shit not starting up side by side wiht ollydbg
2014-01-17T13:42:36 < dongie> ha, beta exe's are not packed :D
2014-01-17T13:42:57 < dongie> time to make a keygen

2014-01-17T13:43:42 < karlp> didn't you say the same thing last time we mentioned this?
2014-01-17T13:43:48 < dongie> troulenceb: obviosuly you've never done visual debugging in a proper IDE like keil
2014-01-17T13:44:05 < Laurenceb> i tried nemiver

2014-01-17T13:45:10 < PaulFertser> dongie: I tried debugging in Keil, couldn't use even some trivial type casts there for some data I needed.

2014-01-17T16:31:10 < dongie> not immediately hang either.

2014-01-17T16:53:04 < Laurenceb> i removed the pullups from the end of the cable and moved them to the plug
2014-01-17T16:53:22 < Laurenceb> now the SCL line couples to the data differently
2014-01-17T16:53:34 < PaulFertser> Laurenceb: after following dongie's advice? ;) what line length is that?
2014-01-17T16:53:35 < Laurenceb> and corrupts the address at the sensor end
2014-01-17T16:53:39 < Laurenceb> 4m
2014-01-17T16:54:06 < Laurenceb> debugging tons of i2c with a scope is a pita
2014-01-17T16:54:23 < Laurenceb> the sensors close to the plug work ok, so theres a load of data inbetween the failures
2014-01-17T16:57:12 < Laurenceb> does i2c clk on rising or falling edges?
2014-01-17T17:00:39 < Laurenceb> hmm rising
2014-01-17T17:00:46 < Laurenceb> so that idea can't be correct

2014-01-17T17:28:58 < Laurenceb> it runs ok with the previous design

2014-01-17T17:30:56 < jpa-> adding series termination resistors can help some
2014-01-17T17:31:02 < Laurenceb> hmm
2014-01-17T17:31:06 < jpa-> i wonder if the trouble is ringing or slow rise time
2014-01-17T17:31:13 < Laurenceb> im wondering if the stm32 is fried
2014-01-17T17:31:31 < Laurenceb> this board previously fried all the sensors it was plugged into
2014-01-17T17:31:49 < Laurenceb> someone snagged a cable and ended up with sda and vcc connected only
2014-01-17T17:32:04 < Laurenceb> that fried the sensors
2014-01-17T17:33:20 < fbs> lol design fail
2014-01-17T17:33:39 < Laurenceb> well it was bound to fry them

2014-01-17T17:35:32 < Laurenceb> i could give up and do CAN bus.. but PCBs would take ages to arrive :-/
2014-01-17T17:38:30 < Steffanx> Not if you spend a few more bucks and order someone in europe..
2014-01-17T17:38:57 < Laurenceb> cant for work projects
2014-01-17T17:39:07 < zyp> like man^Wpcbtrain?
2014-01-17T17:39:55 < Steffanx> Yes like man^Wpcbtrain :)
2014-01-17T17:40:11 < jpa-> man the pcb trains
2014-01-17T17:45:49 < Laurenceb> i wonder if the devices can't cope with a 1k pullup?
2014-01-17T17:45:54 < Laurenceb> sounds likely?
2014-01-17T17:46:12 < jpa-> read the datasheet?
2014-01-17T17:47:15 < zyp> it should be obvious on the scope when the devices aren't driving enough
2014-01-17T17:47:31 < zyp> because the ack won't be at neither vcc nor gnd
2014-01-17T17:48:26 < jpa-> yeah, would look like   http://koti.kapsi.fi/jpa/stuff/pix/i2c_levels.png   or something
2014-01-17T17:48:43 < jpa-> though because Laurenceb's fails are intermittent, may be difficult to catch on a scope
2014-01-17T17:50:00 < zyp> no, the fails would be consistent, they would just be in the undefined range
2014-01-17T17:50:14 < Laurenceb> http://i.imgur.com/3cjuEwP.jpg
2014-01-17T17:50:21 < Laurenceb> doesnt look like its trying ot pull?
2014-01-17T17:50:51 < zyp> no
2014-01-17T17:50:57 < zyp> but where's the ack?
2014-01-17T17:51:18 < zyp> I suggest offsetting scl and sda so they are actually readable

2014-01-17T17:51:28 < Laurenceb> ok
2014-01-17T17:51:43 < Laurenceb> ack is the last pulse - address is 0x30
2014-01-17T17:51:45 < jpa-> perhaps also focusing the camera
2014-01-17T17:51:52 < Laurenceb> focus is jammed
2014-01-17T17:52:36 < jpa-> that glitch between the two '1' bits seems strange
2014-01-17T17:52:46 < Laurenceb> its capacitive coupling
2014-01-17T17:52:50 < Laurenceb> to the SCL line
2014-01-17T17:52:51 < zyp> is 0x30 an 8-bit addr?
2014-01-17T17:52:54 < jpa-> ah
2014-01-17T17:52:57 < Laurenceb> yes
2014-01-17T17:53:23 < jpa-> i wonder if your coupling (capacitive or inductive) might be causing extra pulses also on SCL
2014-01-17T17:53:52 < Laurenceb> hmm
2014-01-17T17:54:00 < Laurenceb> the SDA risetime is slowish
2014-01-17T17:54:01 < zyp> ok, so that's 0x18+R
2014-01-17T17:54:07 < Laurenceb> so no positive spikes on SCL
2014-01-17T17:54:40 < jpa-> a negative spike during the positive cycle also causes a positive spike
2014-01-17T17:54:51 < zyp> ah, no, 0x18+W
2014-01-17T17:54:54 < zyp> wat
2014-01-17T17:55:20 < jpa-> (when it returns to '1' state after the spike passes)
2014-01-17T17:55:21 < Laurenceb> jpa-: but SDA never drops when SCL high
2014-01-17T17:55:31 < jpa-> Laurenceb: start/stop?
2014-01-17T17:55:43 < Laurenceb> hmm
2014-01-17T17:55:47 < zyp> if I'm reading it right, the ack is the first 1-bit
2014-01-17T17:56:24 < Laurenceb> zyp: there are 9 clk pulses after the rep start
2014-01-17T17:56:26 < jpa-> Laurenceb: anyway, it could even ring enough to cause extra pulses on SCL
2014-01-17T17:56:28 < zyp> 00110000 1 <- that's how I'm reading addr/ack
2014-01-17T17:56:38 < Laurenceb> then another rep start as it tried another device
2014-01-17T17:56:44 < Laurenceb> hmm
2014-01-17T17:57:06 < Laurenceb> zyp: me too
2014-01-17T17:57:10 < Laurenceb> so no ack?
2014-01-17T17:57:17 < Laurenceb> 0x30, NACK
2014-01-17T17:57:34 < zyp> yes, no ack
2014-01-17T17:58:03 < jpa-> Laurenceb: what IO speed have you set for SCL?
2014-01-17T17:58:05 < zyp> and there's not a second bit after that, that's just part of the repeat start or wtf you're doing
2014-01-17T17:58:36 < Laurenceb> oh shit
2014-01-17T17:58:40 < Laurenceb> i just remebered
2014-01-17T17:58:53 < Laurenceb> this is a "prototype" board
2014-01-17T17:58:55 < zyp> judging by the level of the ack, the device doesn't attempt to drive it at all, so it's likely that the device didn't understand the addr
2014-01-17T17:59:06 < Laurenceb> with no current limiting resistors on the stm32 pins
2014-01-17T17:59:24 < Laurenceb> might explain the issues - i have used other boards for most tests
2014-01-17T17:59:25 < jpa-> trying a lower baudrate is the simplest way to rule out soldering errors / fried chips
2014-01-17T17:59:31 < Laurenceb> maybe it never worked lol
2014-01-17T17:59:41 < Laurenceb> yeah ive reduced it down to 10khz
2014-01-17T17:59:56 < jpa-> so does it work then?
2014-01-17T17:59:59 < Laurenceb> still identical issue, but also still high drop rate on SDA/SCL and the spikes
2014-01-17T18:00:13 < jpa-> hmm yeah, makes sense
2014-01-17T18:00:16 < jpa-> the fall time is the same
2014-01-17T18:00:22 < Laurenceb> i wonder if its the spikes that cause the issue
2014-01-17T18:00:33 < jpa-> i would config the IO pins to 1 MHz to reduce the spikes/ringing
2014-01-17T18:00:42 < Laurenceb> as my other boards where i know it works reliably have current limiting resistors (200ohm)
2014-01-17T18:00:48 < jpa-> probably not the spikes, but it might look very different at some other point of the bus
2014-01-17T18:00:50 < Laurenceb> ok ill try in a sec
2014-01-17T18:01:11 < jpa-> (or at a higher samplerate)
2014-01-17T18:01:48 < karlp> fucking dma'd to a disabled uart_dr
2014-01-17T18:01:54 < karlp> stupid example stupid shit
2014-01-17T18:02:06 < jpa-> a 4 meter bus will ring nicely at around 70 MHz.. a fast I2C interface in some chip might trigger to that
2014-01-17T18:02:08 < karlp> no errors, just complets very fast.

2014-01-17T19:43:40 < bvernoux> hi
2014-01-17T19:43:44 < Laurenceb> the rules fiule was already setup
2014-01-17T19:44:39 < qyx_> any idea of how to produce true random numbers on stm32?
2014-01-17T19:44:54 < bvernoux> using stm32f4
2014-01-17T19:45:00 < qyx_> considering some two transistor noise generators fed into adc input
2014-01-17T19:45:03 < bvernoux> there is a real true random hw
2014-01-17T19:45:27 < qyx_> i will not use 10e F4 if i need F0/F151
2014-01-17T19:45:37 < bvernoux> in that case good luck ;)
2014-01-17T19:45:38 < qyx_> F162 has some crypto functions
2014-01-17T19:45:48 < qyx_> no
2014-01-17T19:45:48 < bvernoux> you will never have a good random function especially for crytpo
2014-01-17T19:45:51 < qyx_> l162
2014-01-17T19:45:58 < jpa-> qyx_: if you don't need a large bitrate, even just using the inherent noise in ADC could work
2014-01-17T19:46:01 < mumptai> us the least significant bits of the ADC
2014-01-17T19:46:18 < bvernoux> i doubt noise on ADC is true random
2014-01-17T19:46:24 < bvernoux> too predictible
2014-01-17T19:46:40 < jpa-> you cannot count every bit towards entropy, sure
2014-01-17T19:47:03 < qyx_> i assume hwrng could be even more predictable
2014-01-17T19:47:04 < mumptai> ohh tell me how to predict it, i want to get rich ;)
2014-01-17T19:47:10 < qyx_> nsa's looking!
2014-01-17T19:47:12 < jpa-> but if you process it properly you can probably extract some 10-1000 bits of entropy per second from the 1MSps noise
2014-01-17T19:47:45 < jpa-> depending on how paranoid you are :)
2014-01-17T19:48:24 < qyx_> i would trust adc noise more than the internal hwrng
2014-01-17T19:48:33 < qyx_> but yes, it depends
2014-01-17T19:48:43 < jpa-> the benefit from hwrng is the speed
2014-01-17T19:49:10 < qyx_> i just need to generate ephemeral keys every couple of minutes
2014-01-17T19:49:20 < qyx_> so there should be no speed problem
2014-01-17T19:54:15 < qyx_> http://www.entropykey.co.uk/tech/
2014-01-17T19:54:16 < qyx_> uhm
2014-01-17T19:56:39 < jpa-> if you don't need the speed, i wouldn't bother with a noise generator.. it seems that a poor design could easily become less noisy in some temperatures / conditions
2014-01-17T19:56:53 < jpa-> whereas the ADC noise won't go away as easily
2014-01-17T19:57:19 < jpa-> (of course if you have a noise generator and still calculate the entropy based on ADC noise, you are extra safe..)

2014-01-18T00:35:39 < Laurenceb_> i hate i2c
2014-01-18T00:48:51 < Steffanx> Finally.. Laurenceb_ :)
2014-01-18T00:50:20 < Laurenceb_> heh
2014-01-18T00:50:55 < Laurenceb_> im wondering what would be faster - try to get it to work or go with RS485 and an stm32 in each enclosure
2014-01-18T00:52:10 < Steffanx> depends if you include the time you have to wait for your crap i guess?
2014-01-18T00:52:15 < Laurenceb_> ill probably make a mockup with cabling and scope test ports
2014-01-18T00:52:20 < Laurenceb_> well its also CE approved
2014-01-18T00:52:22 < Steffanx> *depends on
2014-01-18T00:52:30 < Laurenceb_> so i would have to get the new device through CE
2014-01-18T00:52:51 < Steffanx> oh you actually care about CE :P
2014-01-18T00:52:52 < Laurenceb_> the existing device is a datalogger with "hacked" firmware
2014-01-18T00:53:02 < Laurenceb_> its for fitting into vehicles
2014-01-18T00:53:10 < Laurenceb_> for vibration monitoring
2014-01-18T00:53:21 < Laurenceb_> and ride quality and so on
2014-01-18T00:53:27 < Steffanx> What kind of vehicles? Random cars?
2014-01-18T00:53:34 < Laurenceb_> no, ambulances
2014-01-18T00:53:43 < Steffanx> Ah :)
2014-01-18T00:53:44 < Laurenceb_> RS485 would take at least 6 months
2014-01-18T00:53:52 < Laurenceb_> to get finished
2014-01-18T00:53:55 < Steffanx> To get the CE?
2014-01-18T00:54:04 < Laurenceb_> well - all the work
2014-01-18T00:54:16 < Laurenceb_> design + manufacture + firmware + CE
2014-01-18T00:54:21 < Steffanx> but at least you know its more reliable...
2014-01-18T00:54:37 < Laurenceb_> well i have a few hundred of the exisitng design and there are no issues
2014-01-18T00:54:41 < Laurenceb_> but we need more
2014-01-18T00:54:44 < Steffanx> Supposed to be though

2014-01-18T00:57:18 < Laurenceb_> nope :P
2014-01-18T00:57:37 < Laurenceb_> just some added 0402 resistors might just fix it
2014-01-18T00:57:47 < Laurenceb_> need to investigate filtering i guess

2014-01-18T04:30:16 < dongie> Should be noted the STM32 can be bricked if the PLL is misconfigured for over 168Mhz.  JTAG will start timing out in the halt requests & you'll never be able to reflash it.

2014-01-18T04:47:46 < zyp> what renaming?
2014-01-18T04:47:55 < emeb> the test equip part of the company should have stayed HP - renamed the rest
2014-01-18T04:47:55 < dongie> agilent is now known as "Keysight technologies"
2014-01-18T04:48:12 < emeb> just the non-medical test equip part.
2014-01-18T04:48:32 < zyp> heh
2014-01-18T04:49:24 < emeb> this crazy need to subdivide and compartmentalize. :P

2014-01-18T04:51:50 < dongie> who's avago?

2014-01-18T04:57:54 < dongie> there were better ones
2014-01-18T04:57:54 < englishman> there is only inductor between SW and battery connection?

2014-01-18T05:00:07 < dongie> at 10 its 300-ish for ones that work or 170-ish for ones that dont
2014-01-18T05:00:21 < dongie> apparently its still "sampling", MP in march
2014-01-18T05:00:52 < englishman> hmm ebay seller says LP097QX1-SPA1 is 1024x768

2014-01-18T05:01:00 < englishman> title says ipad3, photo is correct
2014-01-18T05:01:11 < dongie> 'QX' = 2048x
2014-01-18T05:01:20 < zyp> dongie, the 27"?
2014-01-18T05:01:23 < dongie> zyp: yea
2014-01-18T05:02:33 < zyp> hmm, $300 doesn't sound that bad
2014-01-18T05:02:45 < dongie> 170 is even btter
2014-01-18T05:02:52 < dongie> i wonder what their criteria is for "don't work"
2014-01-18T05:02:58 < zyp> not if they don't work
2014-01-18T05:03:01 < dongie> haha
2014-01-18T05:03:12 < dongie> no its just grade shit
2014-01-18T05:03:21 < dongie> A for 300-ish and "Z" for 170
2014-01-18T05:03:51 < zyp> sure, but $1700 for a bunch of panels with dead pixels doesn't sound like a good deal :p
2014-01-18T05:04:18 < dongie> yeah.
2014-01-18T05:04:26 < dongie> at that rate, its probly more liek dead LINES

2014-01-18T05:05:54 < dongie> since 27" is still too big
2014-01-18T05:06:10 < zyp> ah, yeah
2014-01-18T05:06:28 < zyp> I missed the 24" the first time around, I just saw the shitty 28" and the horribly expensive 32"

2014-01-18T05:08:02 < zyp> hmm, 24" is also pretty expensive, norwegian price is $2000
2014-01-18T05:08:10 < dongie> thats just dell tax

2014-01-18T05:12:03 < dongie> some ST80186 or someshti
2014-01-18T05:12:08 < zyp> DDR3 sounds like slow
2014-01-18T05:12:18 < zyp> since it needs to buffer shit
2014-01-18T05:29:07 < dongie> yea duno
2014-01-18T05:29:09 < dongie> it has ddr2/3

2014-01-18T05:29:13 < dongie> for the scaler
2014-01-18T05:31:50 < zyp> since it needs lots of memory, that probably means it has to buffer everything
2014-01-18T05:32:03 < zyp> which makes it slow
2014-01-18T05:33:03 < dongie> sure
2014-01-18T05:33:31 < dongie> probably memory for scaler, OSD, etc.
2014-01-18T05:33:37 < dongie> its probably more of a TV chipset than monitor.

2014-01-18T09:12:59 < GargantuaSauce> in order to be able to run that perl script or make gdb with my makefile, etc
2014-01-18T09:13:16 < GargantuaSauce> oops paste grammar fail
2014-01-18T09:16:04 < FreezingCold> So I'll admit my C skills are pretty lacking
2014-01-18T09:16:48 < FreezingCold> I guess I use the include files from STM32F4-Discovery_FW_V1.1.0?
2014-01-18T09:17:34 < GargantuaSauce> yes you want stm32f4xx.h for sure, and possibly you'll want to use the stdperiph library
2014-01-18T09:17:45 < GargantuaSauce> in which case you'll need to add its files to the compilation of course
2014-01-18T09:18:12 < GargantuaSauce> personally i dislike stdperiph and would rather just poke the registers directly
2014-01-18T09:18:37 < GargantuaSauce> some people use a HAL, check libopencm3
2014-01-18T09:18:55 < GargantuaSauce> or an rtos, chibios is the popular one round these parts
2014-01-18T09:22:32 < FreezingCold> Is this a decent thing to follow? http://embeddedprogrammer.blogspot.ca/2012/09/stm32f4discovery-development-with-gcc.html
2014-01-18T09:23:09 < FreezingCold> Nope?
2014-01-18T09:23:16 < FreezingCold> Well, I usually use vim
2014-01-18T09:49:15 < FreezingCold> I'm a bit lost..
2014-01-18T09:58:27 < GargantuaSauce> there's a lot of stuff to figure out

2014-01-18T10:50:31 < FreezingCold> How would I do that?
2014-01-18T10:51:29 < FreezingCold> should I maybe flash to 0x100000 instead?

2014-01-18T10:52:13 < PaulFertser> You do not need to specify an address, ihex is not binary, it has all the addresses inside.

2014-01-18T12:34:55 < fbs> FreezingCold: its in the blog?
2014-01-18T12:35:10 < fbs>  Eclipse likely won't build the project correctly as it can't find our compiler. (This took me quite some time to figure out. I assume Eclipse does not process /etc/profile and so does not get the PATH environment variables we set earlier.) So go to Eclipse's Preferences > C/C++ > Build > Environment and and add a new variable. Make the name 'PATH' and set the value to '${PATH}:path_to_installed_toolchain'.

2014-01-18T19:19:19 < kuldeepdhaka> anyone has experience with this dev board (for stm32f373 , Chinese version) http://www.thanksbuyer.com/stm32f373-development-kit-cortex-m4-stm32f373vct6-with-2-8-inch-tft-lcd-screen-26074
2014-01-18T19:21:56 < kuldeepdhaka> im looking for stm32f373 dev. board(low cost). just need a simple board with gpio breakout, usb, and power, stlink, and a reset button.
2014-01-18T19:24:54 < gnomad> ST makes plenty of boards like that for under $20.
2014-01-18T19:25:08 < gnomad> you can even get one with an LCD for about $25.
2014-01-18T19:27:44 < karlp> they don't make one with f37x though...
2014-01-18T19:27:52 < karlp> it's the only one that doesn't have a disco board
2014-01-18T19:28:34 < kuldeepdhaka> they make one for f373 but its $250+

2014-01-18T19:29:40 < gnomad> has to be a stm32f373 ?
2014-01-18T19:31:59 < kuldeepdhaka> because of its 3 sdadc's
2014-01-18T19:32:31 < Robint91> I wonder why someone needs such thing?
2014-01-18T19:32:38 < kuldeepdhaka> my first consideration would be stm32f373
2014-01-18T19:32:39 < Robint91> that samplerate ...
2014-01-18T19:33:39 < kuldeepdhaka> i have a special use for its, (interfacing sensor for precision application)   (at least what i expect)
2014-01-18T19:34:37 < emeb> I've got a PCB design you can have for free here: http://ebrombaugh.studionebula.com/embedded/stm32f373breakout/index.html
2014-01-18T19:34:46 < kuldeepdhaka> gnomad, (yea)
2014-01-18T19:34:46 < emeb> tested, working.
2014-01-18T19:35:00 < karlp> what sensor, what precision are you chasing kuldeepdhaka?

2014-01-18T19:36:18 < kuldeepdhaka> emeb, yea (nice work their) but i have lqfp64 IC (not 48 one)
2014-01-18T19:36:38 < kuldeepdhaka> karlp, all sort of :D
2014-01-18T19:39:24 < kuldeepdhaka> karlp, basically use for interfacing sensors at lower speed and they are expected to be more precise
2014-01-18T19:40:00 < kuldeepdhaka> emeb, and pcb is one headache for me
2014-01-18T19:40:17 < kuldeepdhaka> emeb, can i buy it somewhere?

2014-01-18T20:18:32 < emeb> gnomad: it's hard to multiplex sigma delta converters.
2014-01-18T20:19:53 < emeb> their operation depends to a large degree on state that's contained in the SD front-end and a decimation filter that comes afterward.
2014-01-18T20:20:33 < emeb> if you multiplex analog signals into the front-end then you need to let the back-end settle out and that slows them waaaay down.

2014-01-19T04:40:51 < dongie> but not $300 nicer
2014-01-19T04:41:02 < dongie> zyp, logic8 has no buffer.
2014-01-19T04:41:07 < zyp> exactly :p
2014-01-19T04:41:20 < dongie> but they dont evne have sram hooked up to spartan on logic16
2014-01-19T04:41:25 < dongie> so its just wahtever blockram they have
2014-01-19T04:41:27 < dongie> more fail.
2014-01-19T04:41:41 < dongie> R2COM: doesnt logic16 claim 200mhz
2014-01-19T04:41:44 < dongie> on 2 channels
2014-01-19T04:41:50 < zyp> it does?
2014-01-19T04:41:52 < dongie> and halves for each 2
2014-01-19T04:41:54 < dongie> or was it 100?
2014-01-19T04:41:55 < zyp> isn't it 100MHz on 3?
2014-01-19T04:42:18 < dongie> zyp, maybe 100, but Im prety sure it was in pairs
2014-01-19T04:42:23 < dongie> 2 @ 100, 4 @ 50, etc.
2014-01-19T04:42:40 < dongie> theyt had some blog about it somewehre, maybe it was in that teardown?
2014-01-19T04:42:45 < dongie> the trace lengths were matched

2014-01-19T04:43:09 < dongie> i duno
2014-01-19T04:43:46 < dongie> clearly this is not R2COM-style PRO logic analyzer.
2014-01-19T04:43:49 < dongie> its neough for hobby trash.
2014-01-19T04:44:33 < dongie> you mean KEYSENSE
2014-01-19T04:44:57 < zyp> dongie, no, there's 100 MHz on three channels, I've used that mode
2014-01-19T04:45:03 < dongie> R2COM: `agilent -> keysense
2014-01-19T04:45:05 < dongie> zyp: mkay.
2014-01-19T04:45:07 < dongie> dunno then
2014-01-19T04:46:10 < dongie> my pokemon analzyer can do 200mhz on a few channels + it does RLE and transition only
2014-01-19T04:46:29 < dongie> so  you don't need a lot of buffer to log shit that doesnty change a lot
2014-01-19T04:46:35 < dongie> duno if logic has transition, does it?
2014-01-19T04:46:48 < dongie> thats software side anyway,  they should support it if they werent lazy
2014-01-19T04:46:49 < zyp> has what?
2014-01-19T04:46:56 < dongie> transition logging.
2014-01-19T04:47:00 < dongie> so you dont waste buffer logging blanks.
2014-01-19T04:47:02 < zyp> yes
2014-01-19T04:47:27 < zyp> I believe they do transition transfer too, but I dunno

2014-01-19T04:52:46 < dongie> its way too expensive
2014-01-19T04:52:51 < dongie> i think i paid something like 2k
2014-01-19T04:53:15 < zyp> hmm
2014-01-19T04:53:31 < dongie> but software is awesome, and best of all support is awesome. emails replied almsot instantly
2014-01-19T04:54:33 < zyp> dongie, can it trigger on clock signals?
2014-01-19T04:54:36 < dongie> internal design is similiar. io buffer, fpga, high speed sram. but they do some triggering and stuff in fpga instead of just dumping to usb. it also has no 'realtime' mode. so its just capture _> send
2014-01-19T04:54:40 < dongie> zyp: yeah
2014-01-19T04:54:40 < zyp> I mean, sample on clock signals
2014-01-19T04:54:48 < dongie> you have external trigger probe
2014-01-19T04:54:55 < dongie> you can use that to whatever
2014-01-19T04:55:01 < dongie> or setup a channel for that
2014-01-19T04:55:50 < zyp> I could use something that's able to grab rather fast parallel buses
2014-01-19T04:56:33 < dongie> zyp, it has 'external clock' mode
2014-01-19T04:57:13 < dongie> doesnt look liek you can assign a chanel as a clock, bute it has a mcx conenctor on teh side for external probe/input - thats probly where it goes. never used that.
2014-01-19T04:57:36 < zyp> doesn't matter as long as it's fast enough to oversample
2014-01-19T04:59:14 < zyp> hmm, the PKLA series looks rather cheap
2014-01-19T05:00:14 < dongie> you can combine channels to display stuff yeah
2014-01-19T05:00:16 < dongie> like buses etc
2014-01-19T05:01:40 < zyp> which of them do you have?
2014-01-19T05:02:07 < dongie> i have the TL136 something or other jap branded version
2014-01-19T05:02:09 < dongie> lemme check
2014-01-19T05:02:30 < dongie> TL2136B that yeah
2014-01-19T05:02:48 < dongie> http://www.acute.com.tw/busdecode.php check out all their bus decoders
2014-01-19T05:03:00 < dongie> hey it can decode swd
2014-01-19T05:04:09 < zyp> huh, this store lists TL2136
2014-01-19T05:04:14 < zyp> older model or something?
2014-01-19T05:04:49 < zyp> and even a TL2036 which only has 180kb of sample memory
2014-01-19T05:05:27 < zyp> TL2136 is 775 EUR
2014-01-19T05:06:04 < dongie> TL2136B ?
2014-01-19T05:06:20 < talsit> software can also do their oscilloscope, and combine both in the same window - nice
2014-01-19T05:06:35 < zyp> dongie, no, it says TL2136
2014-01-19T05:06:47 < dongie> duno then. does it say 18mbit memory?

2014-01-19T05:38:00 < zyp> and there's no 180k version of the B-variant

2014-01-19T05:44:58 < zyp> I saw the jp one were 125k yen
2014-01-19T05:45:10 < dongie> ripoff
2014-01-19T05:45:26 < zyp> yeah, that's a bit more than the 775 EUR one

2014-01-19T05:46:18 < dongie> i jewed htem down a bit and got them to include the micro clips

2014-01-19T05:46:30 < dongie> in like 2008
2014-01-19T05:46:45 < zyp> ah
2014-01-19T05:47:19 < dongie> byut yeah, probably not -B version
2014-01-19T05:47:23 < dongie> since they offer 180k type.
2014-01-19T05:48:20 < zyp> I'm seriously considering getting one, when I have some money left over for it

2014-01-19T06:01:18 < dongie> duno then
2014-01-19T06:01:51 < dongie> maybe they wrote their own software since logic one sucks so bad.

2014-01-19T06:05:03 < zyp> it does that
2014-01-19T06:05:20 < dongie> between arbitrary pulses? or just from edge to edge
2014-01-19T06:05:33 < dongie> i know it shows distance between edge/edge
2014-01-19T06:05:36 < dongie> er time/wahtever
2014-01-19T06:05:52 < dongie> say i wanna measure how long one i2c transation takes from start to stop
2014-01-19T06:06:02 < dongie> can i drag a marker to do that?
2014-01-19T06:06:13 < zyp> there are two time markers, they call them T1 and T2, you can put them anywere or snap them to edges
2014-01-19T06:06:19 < dongie> mkay.
2014-01-19T06:06:25 < zyp> and then you get time between them and between each of them and trigger point

2014-01-19T06:07:21 < dongie> how is that done?
2014-01-19T06:07:36 < dongie> do they wait for some communication or something or wat
2014-01-19T06:07:44 < zyp> hmm, I seem to recall there was something in hub spec about led control

2014-01-19T06:10:41 < dongie> or do you need separate ones for 1.0/2.0/3.0
2014-01-19T06:10:50 < dongie> i mean does 3.0 cover evrything below, or just 3.x
2014-01-19T06:11:04 < zyp> dunno, I haven't read 3.0 spec
2014-01-19T06:11:32 < zyp> dunno, depends on the software
2014-01-19T06:11:42 < englishman> why not logic16 for $22?
2014-01-19T06:11:58 < englishman> use sigrok then
2014-01-19T06:12:02 < englishman> no guilt
2014-01-19T06:12:05 < dongie> it might be usable with sigrok software

2014-01-19T14:15:05 < karlp> I bought a logic16 clone on aliexpress for $22 that englishman found, no idea how well it will work yet,
2014-01-19T14:15:20 < karlp> the sigrok guys are very actively working on the lwla34 and lwla16 stuff,
2014-01-19T14:15:53 < karlp> the rigol 1052d, with the logic analyser addition doesn't do _any_ protocol decoding
2014-01-19T14:16:00 < karlp> oh, r2com's left anyway
2014-01-19T14:18:33 < PaulFertser> I tried using http://www.ebay.com/itm/160931284302?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 (Siglent) and the UI felt very sane and cool, better than old Tektronix, much better than "owen".

2014-01-19T14:22:02 < karlp> somewhat shady with "modified" saleae software, but was planning on usin git with sigrok anyway.
2014-01-19T14:22:09 < karlp> but, hasn't gotten here yet :)
2014-01-19T14:22:43 < fbs> git? how does that work
2014-01-19T14:22:51 < karlp> sigrok
2014-01-19T14:22:57 < karlp> using it
2014-01-19T14:22:59 < fbs> oh lol
2014-01-19T14:23:00 < karlp> not usin git
2014-01-19T14:23:49 < fbs> i still got 2 usbee clones i should use oneday
2014-01-19T14:23:57 < fbs> got to figure out how to use sigrok
2014-01-19T14:24:11 < karlp> yeah, it's not really full of "getting started" docs
2014-01-19T14:24:39 < karlp> from the irc channel and a video from 30c3, sounds like there's been a _lot_ of development over the last 3-4 months compared to the last year or two
2014-01-19T14:24:53 < fbs> nice

2014-01-19T16:07:29 < emeb> zyp: not really. just tedious setup
2014-01-19T16:07:52 < zyp> I'd imagine it's pretty similar to how you would set up DMA and clocks and stuff for I2S, except you have more than two channels in the stream
2014-01-19T16:07:57 < zyp> and more configuration options
2014-01-19T16:08:06 < emeb> zyp: pretty much
2014-01-19T16:08:19 < emeb> DMA is identical, just different DRs
2014-01-19T16:08:42 < emeb> SAI configuration took some study
2014-01-19T16:08:54 < emeb> I'm just doing I2S protocol
2014-01-19T16:09:09 < zyp> dongie, those ws2812 led strips, would they run at 5V?
2014-01-19T16:09:40 < zyp> the datasheet says 6-7V, but I see them sold as both 5V and 12V
2014-01-19T16:09:55 < dongie> 2812? hm.. i've ran them at 5V just fine yes
2014-01-19T16:12:34 < dongie> they defnitely do not run at 12V
2014-01-19T16:12:40 < dongie> they smoke at 12V
2014-01-19T16:13:01 < zyp> dunno, maybe the strips sold as 12V have some more shit on them
2014-01-19T16:17:14 < dongie> maybe those are 2801
2014-01-19T16:17:21 < dongie> they can be wired to run off 12V
2014-01-19T16:17:26 < dongie> with 3 leds/channel
2014-01-19T16:17:33 < zyp> ah, that might be

2014-01-19T16:19:18 < zyp> do you happen to have a figure of the current draw at 5V?
2014-01-19T16:19:30 < dongie> like whaT? per pixel?
2014-01-19T16:19:40 < dongie> its just regular led
2014-01-19T16:19:45 < dongie> so comparable
2014-01-19T16:19:50 < dongie> the driver itself doesnt draw much
2014-01-19T16:19:59 < zyp> I just wonder how many I'd be able to run directly off usb
2014-01-19T16:20:04 < dongie> lots.
2014-01-19T16:20:12 < zyp> sure, but what's the max current?
2014-01-19T16:20:24 < dongie> 20mA*3
2014-01-19T16:20:27 < dongie> per pixel
2014-01-19T16:20:53 < bvernoux> hi
2014-01-19T16:21:05 < zyp> so 8 is lots? :p
2014-01-19T16:21:23 < dongie> zyp: http://www.youtube.com/watch?v=knJWK7gcZOY
2014-01-19T16:21:26 < dongie> this is 1A
2014-01-19T16:21:54 < zyp> is that at full brightness?
2014-01-19T16:21:57 < dongie> ya
2014-01-19T16:22:10 < dongie> well duno. i dont have that sores
2014-01-19T16:22:12 < dongie> probly close to full
2014-01-19T16:22:41 < dongie> lol @ 4 dislikes
2014-01-19T16:22:43 < dongie> fuckin faggots
2014-01-19T16:22:54 < fbs> that music
2014-01-19T16:23:25 < zyp> of course, it's only 60 mA when all colors are 100%
2014-01-19T16:23:43 < dongie> fbs: is awesome
2014-01-19T16:23:49 < dongie> is waht you mean?
2014-01-19T16:24:05 < zyp> so if only one color is at 100% on average, that's only 20mA each
2014-01-19T16:24:21 < fbs> can you put them in series?
2014-01-19T16:24:26 < dongie> ?
2014-01-19T16:24:32 < zyp> fbs, that's the point
2014-01-19T16:24:53 < zyp> fbs, you chain them and stream out the values for all over a single data line
2014-01-19T16:24:54 < dongie> they';re clocking crap out to next
2014-01-19T16:24:59 < dongie> yea
2014-01-19T16:25:01 < fbs> not data, power
2014-01-19T16:25:04 < fbs> vcc to gnd
2014-01-19T16:25:09 < dongie> no
2014-01-19T16:25:27 < fbs> lame
2014-01-19T16:25:40 < zyp> of course you can't, they have a built in controller chip

2014-01-19T16:54:29 < dongie> zyp, let's dickstart a portable Qi charger that runs off a lipo battery.
2014-01-19T16:54:56 < dongie> so you could like charge your dixus5 without plugging it in
2014-01-19T16:55:56 < jpa-> wasn't there just that on drop-kicker now? :)
2014-01-19T16:56:17 < dongie> exactly but their idea sucks
2014-01-19T16:57:00 < jpa-> which makes it worth replicating :)

2014-01-19T16:59:33 < jpa-> hmm.. what does it need the focus screen for?
2014-01-19T16:59:36 < dongie> you've been dickstarted
2014-01-19T16:59:41 < dongie> wtf is a focus screen
2014-01-19T17:00:02 < jpa-> a piece of glass/plastic with a matt surface that an image can be projected on
2014-01-19T17:01:19 < jpa-> apparently it projects the image from the objective on a focus screen inside the device and then the iphone takes a photo of the screen.. i wonder how well that will ruin quality :)

2014-01-19T17:02:46 < dongie> yes, perfect idea
2014-01-19T17:02:52 < dongie> zyp, time to dickstart
2014-01-19T17:02:55 < jpa-> then you can just arrange them on the floor in a huge domino circle :)
2014-01-19T17:02:56 < dongie> prototypes not necessary
2014-01-19T17:03:07 < zyp> just throw together a lipo, that TI Qi sender chip, some charging controller for the lipo and put it in a neat package
2014-01-19T17:03:33 < dongie> < jpa-> make it support qi charging itself also
2014-01-19T17:03:33 < dongie> THIS
2014-01-19T17:03:35 < dongie> is the game changer.

2014-01-19T17:04:27 < zyp> then you could just have a sleeve on the charger which you slip the phone into to keep it in place when charging
2014-01-19T17:05:12 < zyp> should fit nicely in a large pocket, without the hassle of a usb cable running between the battery and charger like other portable chargers have
2014-01-19T17:05:14 < dongie> and and and
2014-01-19T17:05:23 < dongie> if you stack them together
2014-01-19T17:05:25 < dongie> like
2014-01-19T17:05:31 < dongie> they will get cooler

2014-01-19T17:11:16 < dongie> 3) bigger than xbox one
2014-01-19T17:11:45 < zyp> isn't that the point of prototypes? :p
2014-01-19T17:14:34 < zyp> the size doesn't look that bad, provided that they'll actually fill it with a larger battery than shown in the prototype pics

2014-01-19T19:13:41 < zyp> :D
2014-01-19T19:14:32 < emeb> stupid Wolfson codec's I2C config interface is a nuisance.
2014-01-19T19:14:43 < emeb> but 3-wire SPI-ish config works fine.
2014-01-19T19:15:23 < zyp> how so?
2014-01-19T19:15:57 < emeb> In I2C mode it wasn't ACKing the I2C transfers.
2014-01-19T19:16:12 < emeb> so I put it in SPI mode and bitbanged it and it works.
2014-01-19T19:16:18 < zyp> wrong addr?
2014-01-19T19:16:30 < emeb> Same address I've always used.
2014-01-19T19:16:42 < emeb> and other things on that I2C bus were working fine.
2014-01-19T19:16:48 < zyp> forgot to set open-drain mode?
2014-01-19T19:16:59 < emeb> nope.
2014-01-19T19:17:09 < emeb> other things on the bus ACK just fine.
2014-01-19T19:17:25 < zyp> sure, that depends on the drive strength
2014-01-19T19:17:45 < zyp> I did that mistake once, and had one device working but not the other on the same bus
2014-01-19T19:18:16 < emeb> Disco board I2C3 has 4.7k pullups on it and I had OD set. Edges looked fast enough.
2014-01-19T19:18:32 < zyp> ok
2014-01-19T19:20:08 < emeb> Anyway - SAI looks good.
2014-01-19T19:20:35 < emeb> Now need to fire up the SDRAM and make a huge audio delay...

2014-01-19T19:32:01 < PaulFertser> How does different debugging gear act on attaching debuggers? E.g. BMP halts the target as soon as gdb is attached. OpenOCD does nothing, sometimes refusing GDB from connecting altogether (when it can't prepare memory map). gdbserver stops the target app immediately upon launch. How about other stuff? How professional debuggers handle gdb (or other debug agent) connection, do they halt the target?

2014-01-19T19:38:40 < Robint91> a simple "halt" command should be mandatory

2014-01-19T19:40:58 < Robint91> PaulFertser, a debugger should do as least as possible to the target
2014-01-19T19:41:01 < PaulFertser> Robint91: hm, ok, there's actually "background execution mode" and you can use "interrupt" there.

2014-01-19T19:42:10 < Robint91> PaulFertser, I think the most commond behavious is halt on connection

2014-01-19T19:43:40 < PaulFertser> Robint91: I'm afraid that not halting on connection is confusing for the majority of the users, as they're not used to working with "target-async" gdb mode (hey, even I'm trying it for the first time atm!)
2014-01-19T19:44:48 < Robint91> PaulFertser, I mostly use printf statements to debug

2014-01-19T20:04:40 < PaulFertser> fbs: if you mean "mon halt" then it's not really ok, openocd-specific and also you do not have valid data in gdb after that command, the register contents are still bogus.
2014-01-19T20:04:53 < zyp> gxti, as long as the port is 5V tolerant
2014-01-19T20:05:14 < gxti> obviously

2014-01-19T20:06:57 < PaulFertser> fbs: right, but probably openocd is doing the wrong and confusing thing here, that's my point.

2014-01-19T20:13:58 < PaulFertser> Robint91: i think if you do not want gdb to stop the target on attach you should do "set target-async on" before connecting. Would you agree it'd be ok to stop the target if async mode is not used if async mode works properly when enabled?
2014-01-19T20:15:00 < gxti> halting by default seems to make the most sense

2014-01-19T20:19:13 < zyp> I don't see the problem with having gdb halt the target on attach
2014-01-19T20:19:27 < fbs> same
2014-01-19T20:20:26 < zyp> you have a pretty specific/weird need if you need to be able to attach to a running target without halting it for a second or two
2014-01-19T20:21:13 < zyp> because if halting is causing problems, just make sure that you attach before starting it, i.e. reset the target after you've attached
2014-01-19T20:21:31 < jpa-> such situations happen, but it's ok having to invoke a special mode for that
2014-01-19T20:21:35 < zyp> otherwise just do a continue after you've attached
2014-01-19T20:22:17 < jpa-> (and you might need some extra funniness in that case.. e.g. if you need to hook up a debug cable on the fly, the capacitance on the reset wire can be a trouble..)
2014-01-19T20:23:02 < Robint91> I wonder, how difficult is it to make a gdb debugger, not something that needs open-ocd
2014-01-19T20:23:13 < Robint91> but a real debugger with a gdb interface
2014-01-19T20:23:18 < emeb> Hmmm...
2014-01-19T20:23:21 < jpa-> Robint91: you mean, like, a black magic probe?
2014-01-19T20:23:27 < jpa-> that would be a great name for it
2014-01-19T20:23:28 < emeb> looks like a data alignment problem.
2014-01-19T20:24:11 < emeb> bits aren't in the right place - overlapping frame boundaries. Works fine if I pass-thru, but as soon as I alter data it goes weird.
2014-01-19T20:24:18 < zyp> jpa-, the main reason to attach to a running target would be to inspect the state after observing weird behavior
2014-01-19T20:24:38 < zyp> but in that case you'll want to halt it to inspect it anyway

2014-01-19T20:25:09 < jpa-> zyp: well, it could also be a weird behaviour of only a part of it.. but yeah, could probably infer most of it from the halted state
2014-01-19T20:25:40 < jpa-> if the running system has watchdog enabled, that could cause a need to not stop it
2014-01-19T20:25:46 < zyp> I've done that a couple of times to grab the usb log
2014-01-19T20:25:53 < zyp> never had problems with reset capacitance
2014-01-19T20:26:04 < Robint91> jpa-, yes?
2014-01-19T20:26:53 < zyp> jpa-, DBGMCU can stop the watchdog along with the CPU
2014-01-19T20:27:45 < zyp> though, that has to be enabled
2014-01-19T20:29:34 < jpa-> zyp: it probably helps if the debugger keeps NRST high.. but mine is just stlinkv1, though i have reset wire in the cable it's not connected anywhere
2014-01-19T20:30:14 < zyp> I believe BMPM configures NRST to OD
2014-01-19T20:31:11 < zyp> it's not pulled up by the BMP, that's why I had problems with lpc43xx and had to ghetto on a pullup on reset
2014-01-19T20:32:06 < gxti> you never want to drive srst high, some chips (like stm32...) actually pull the line directly to do software reset, so if it's driven high software reset stops working
2014-01-19T20:32:07 < PaulFertser> Didn't the target board had pullup (probably inside the chip)?
2014-01-19T20:32:17 < jpa-> hmm.. i wonder if the chip on my board was somehow just extra sensitive, as i didn't have the trouble with another board of the same design
2014-01-19T20:32:20 < gxti> very amusing when i ran into that
2014-01-19T20:32:51 < zyp> PaulFertser, I designed the board, and I omitted the pullup, relying on the chip having an internal one like stm32
2014-01-19T20:32:55 < gxti> you can make it less sensitive by always including a pullup resistor, i try not to rely on the builtin one if there even is one
2014-01-19T20:33:19 < jpa-> i had 10kohm pull-up
2014-01-19T20:33:28 < PaulFertser> I see
2014-01-19T20:33:39 < zyp> PaulFertser, the documentation was a bit unclear on whether there was an internal pullup or not, but seemed to indicate that it had one
2014-01-19T20:33:59 < PaulFertser> zyp: funny. Is NXP's documentation no better than ST's?
2014-01-19T20:34:01 < zyp> but in practice it didn't work like that
2014-01-19T20:34:11 < zyp> dunno
2014-01-19T20:34:17 < zyp> is ST's documentation bad?
2014-01-19T20:34:48 < PaulFertser> zyp: imho, some of ST's documentation is very bad.
2014-01-19T20:34:59 < upgrdman> s/some/most
2014-01-19T20:35:11 < jpa-> gxti: it's also funny how the STM32 reset circuitry is fed from the Vadc.. i once had a bad solder connection on that pin and NRST just stayed low so programs wouldn't run even though debugger connected fine
2014-01-19T20:35:30 < zyp> having worked way more with stm32 than any other chip families, I'm pretty familiar with ST documentation
2014-01-19T20:36:12 < zyp> so I can't really give an unbiased opinion of other vendor's documentation, since just the fact that they are unfamiliar makes them harder to read
2014-01-19T20:41:59 < PaulFertser> Thank you for the feedback on debugger, folks.

2014-01-19T21:25:51 < gxti> i could get by with just some pullups but i don't know how fast i can go without burning a lot of current
2014-01-19T21:26:16 < bvernoux> something simpler is just to use an stm32f4 ;)
2014-01-19T21:28:01 < jpa-> gxti: check or guess the input capacitance, calculate from there
2014-01-19T21:28:51 < gxti> bvernoux: what does that have to do with anything?
2014-01-19T21:29:05 < jpa-> i bet some 10kohm pull-ups are plenty fast enough for anything that you'd want to do with a character LCD
2014-01-19T21:29:15 < bvernoux> gxti: why you need all that crap for an LCD ?
2014-01-19T21:29:31 < jpa-> level shifting from 3.3V to 5V
2014-01-19T21:29:46 < bvernoux> hmm
2014-01-19T21:30:01 < gxti> jpa-: you're probably right, i should stick the pullups and live with whatever max speed i end up with
2014-01-19T21:30:31 < gxti> using 25p as a random-ass guess it looks like i can't get 1mhz but i guess i don't care. i've never done character lcds before so i don't know what kind of speed i really need.
2014-01-19T21:31:23 < jpa-> the LCs on them usually take some 50ms to react
2014-01-19T21:31:30 < gxti> i could use the full 8 bits as well but not on one contiguous port
2014-01-19T21:32:24 < gxti> i really wish i knew why uC manufacturers insist on fucking up pinouts completely. it's one thing to omit some pins from a bank when downscaling packages, it's another for a bank to be spread all over the package for no apparent reason.
2014-01-19T21:32:26 < jpa-> another way would be to use a shift register from the HCT series to drive it
2014-01-19T21:33:39 < zyp> doesn't HD44780 normally work fine on 3.3V signals?

2014-01-19T21:42:31 < emeb> same code pointing at SRAM for buffer works fine.
2014-01-19T21:42:56 < emeb> only difference is base pointer type & starting address...
2014-01-19T21:43:43 < jpa-> why different pointer type?
2014-01-19T21:44:33 < emeb> because example code was adding volatile.
2014-01-19T21:44:50 < emeb> removing volatile didn't alter behavior though.
2014-01-19T21:45:24 < jpa-> sdram access is slower than sram, maybe you are invoking some timing issues?
2014-01-19T21:45:39 < jpa-> race condition or similar
2014-01-19T21:46:15 < emeb> all that should do is slow down the code execution, right?
2014-01-19T21:46:28 < emeb> I'm looking at execution time - plenty of slack.
2014-01-19T21:47:01 < jpa-> yeah - but if the code is complex, slowing down execution might cause some bugs to surface

2014-01-19T21:49:26 < bvernoux> maybe you changed the CPU freq
2014-01-19T21:49:36 < emeb> if I stop execution and examine the contents of the SDRAM w/ gdb, all the data has high byte = 0

2014-01-19T21:51:09 < bvernoux> I imagine default SDRAM timing are optimized for 168Mhz core
2014-01-19T21:51:24 < bvernoux> else you need to change all the ras, cas ...
2014-01-19T21:52:04 < bvernoux> 180Mhz is for commercial ;)
2014-01-19T21:52:10 < bvernoux> use always 168Mhz ;)
2014-01-19T21:53:08 < emeb> No effect
2014-01-19T21:54:55 < bvernoux> ha
2014-01-19T21:56:34 < emeb> still doing that strange 0x00 top byte thing too.
2014-01-19T22:00:07 < zyp> are you sure you have the controller configured for the correct bus width?

2014-01-20T03:01:07 < dongie> Laurenceb_: yes
2014-01-20T03:01:10 < dongie> it works
2014-01-20T03:01:22 < dongie> you just enable passthrough register, and it connects to aux i2c bus
2014-01-20T03:01:23 < dongie> nothing else to do
2014-01-20T03:01:28 < Laurenceb_> ah
2014-01-20T03:01:33 < Laurenceb_> so its literally connected?
2014-01-20T03:01:36 < dongie> yes
2014-01-20T03:01:39 < dongie> its just analog switch
2014-01-20T03:01:44 < Laurenceb_> that means i cant do anything interesting
2014-01-20T03:01:55 < Laurenceb_> but i could use the inbuilt mastering

2014-01-20T03:02:06 < dongie> yes, that works, but its really nasty to work with
2014-01-20T03:02:21 < Laurenceb_> seems simple enough from datasheet
2014-01-20T03:02:24 < Laurenceb_> is it buggy?
2014-01-20T03:03:00 < Laurenceb_> think im going to redo my hardware with 3x MPU-9250 and PCA9600
2014-01-20T03:03:26 < dongie> well, it works. quirky but works. I dont remember since its been a while i used it.
2014-01-20T03:03:45 < Laurenceb_> ok ill use it to hide the third mpu-9250
2014-01-20T03:04:13 < Laurenceb_> only a new cable to redo CE for
2014-01-20T03:04:28 < Laurenceb_> i can hide a PCA9600 in the plug

2014-01-20T11:32:10 < dongie> haha
2014-01-20T11:32:30 < dongie> why dont they take either register or index for all??
2014-01-20T11:33:13 < zyp> not to mention that the latter takes pointers to a rx-buffer and a tx-buffer, and apparently I have to supply both
2014-01-20T11:33:36 < dongie> no shortcut of NULL not to do one of the buffers?
2014-01-20T11:33:38 < zyp> so if I just want to receive 100 bytes, I guess I have to also submit a 100 byte tx-buffer
2014-01-20T11:33:47 < dongie> silly
2014-01-20T11:33:47 < zyp> dunno, doesn't say
2014-01-20T11:34:01 < dongie> just point to same buffer
2014-01-20T11:34:12 < zyp> yeah, that's what I figure
2014-01-20T11:34:14 < zyp> should work
2014-01-20T11:37:41 < zyp> oh, spi_master_init returns the base addr pointer that I'm supposed to use
2014-01-20T11:37:43 < zyp> but still
2014-01-20T11:37:57 < dongie> well thats not so bad  t hen.

2014-01-20T11:49:16 < zyp> there's a SPIFrequency_t define, but no function taking that type

2014-01-20T12:11:24 < zyp> spi_master_tx_rx() controls the SS line
2014-01-20T12:12:18 < zyp> so apparently you're not supposed to have multiple slaves hooked up, or split a transfer without deasserting SS between
2014-01-20T12:12:51 < dongie> cool
2014-01-20T12:13:07 < zyp> just more bullshit
2014-01-20T12:13:41 < zyp> I guess I'll just ignore the SS pin and hook up another and use that instead

2014-01-20T13:30:21 < dongie> according to the fucking schematic it would be lower. because they have dvdd -> bead -> avdd

2014-01-20T13:33:02 < dongie> wat
2014-01-20T13:33:20 < zyp> DVDD can be lower than AVDD, or up to 0.2V higher
2014-01-20T13:33:40 < dongie> AD_DVDD <= ( AD_AVDD + 0.2V ) this makes no difference?
2014-01-20T13:33:47 < dongie> or wat
2014-01-20T13:34:10 < zyp> if AVDD is 3.3V then DVDD can be anywhere from 0 to 3.5V
2014-01-20T13:34:36 < zyp> if DVDD is 3.3V then AVDD must be at least 3.1V

2014-01-20T19:13:52 < zyp> on f429-discovery?
2014-01-20T19:13:57 < emeb> yeah.
2014-01-20T19:14:02 < emeb> acting really weird.
2014-01-20T19:14:49 < emeb> if I do individual accesses in an unrolled loop then I can read/write full 16-bit data and it's persistent and reliable.
2014-01-20T19:15:29 < emeb> but when I try to write a buffer of I2S data with a loop in my ISR then the data gets mangled.
2014-01-20T19:16:04 < emeb> but if I just point that same loop at an address in SRAM it works fine.

2014-01-20T19:17:08 < emeb> the data in SDRAM appears as though it's been sign extended from 8bits to 16 bits.
2014-01-20T19:17:44 < emeb> so if bit 7 is set on the data I write, then bits 7-15 are set when I read, etc.

2014-01-20T19:22:40 < zyp> in both cases?
2014-01-20T19:22:44 < emeb> yes
2014-01-20T19:23:14 < zyp> seen the notes about interrupts in the errata?

2014-01-20T19:23:44  * emeb heads off to the st.com site...
2014-01-20T19:24:05 < zyp> 2.8.4 should be fixed in Y silicon though
2014-01-20T19:24:24 < zyp> and I'm not sure it would be relevant anyway
2014-01-20T19:24:37 < zyp> 2.8.5 is not fixed, try the workaround
2014-01-20T19:28:47 < emeb> enabling read burst doesn't seem to have helped.
2014-01-20T19:29:31 < emeb> but it is interesting - the "good" behavior is seen in foreground during setup. "bad" behavior happens during ISR context.
2014-01-20T19:29:50 < zyp> yes, that's what I was thinking
2014-01-20T19:30:08 < zyp> not completely like the description in the errata, but still somewhat related
2014-01-20T19:30:14 < emeb> yes

2014-01-20T21:32:38 < bvernoux> it is not in errata of STM32F4
2014-01-20T21:32:39 < emeb> immediately after writing to an SDRAM data location, the data is fine (as displayed in gdb)
2014-01-20T21:32:58 < emeb> but on the next instruction step it all changes.
2014-01-20T21:33:14 < emeb> even locations not accessed.
2014-01-20T21:33:22 < bvernoux> emeb: you have definitely a timing/conf issue or even maybe a HW problem
2014-01-20T21:33:53 < emeb> bvernoux: but interestingly, using the ST-supplied SDRAM test code it checks out fine.

2014-01-20T21:45:28 < bvernoux> the SDRAM is cached
2014-01-20T21:46:02 < emeb> ok. how to test it?
2014-01-20T21:46:27 < bvernoux> especially when debugging
2014-01-20T21:46:37 < bvernoux> maybe this error does not happen out of debugger
2014-01-20T21:47:15 < emeb> behavior in the debugger doesn't exactly match what I see in realtime.
2014-01-20T21:47:27 < emeb> ie - upper byte corruption
2014-01-20T21:47:31 < kuldeepdhaka> jpa-, yea most handler are weak alias of  default_handler
2014-01-20T21:47:41 < bvernoux> also dst is not volatile in your test

2014-01-20T21:48:39 < bvernoux> you should not have issue
2014-01-20T21:48:58 < emeb> that seems far-fetched.
2014-01-20T21:49:17 < emeb> out-of-order memory writes would completely kill predictable hardware initialization.

2014-01-20T21:49:42 < bvernoux> but it is not the case on Cortex IIRC
2014-01-20T21:49:55 < jpa-> anyway, whatever the CPU reads should be consistent with what it writes
2014-01-20T21:50:04 < bvernoux> only on bigger CPU it is why there is memory area for that
2014-01-20T21:50:08 < bvernoux> to ensure in order
2014-01-20T21:50:14 < bvernoux> especially on peripheral ...
2014-01-20T21:50:21 < jpa-> instructions may be reordered and in some cases that might have some effect for debugging, but not sure..
2014-01-20T21:50:23 < bvernoux> with an MPU
2014-01-20T21:50:40 < emeb> I don't see these isssues when accessing SRAM. that works fine. only SDRAM is strange.
2014-01-20T21:50:42 < bvernoux> yes for debugging when you check vs C code
2014-01-20T21:51:10 < bvernoux> The Cortex-M processors never perform memory accesses out of order compared to instruction flow, however, the architecture does not prohibit this in future
2014-01-20T21:51:10 < jpa-> emeb: maybe you can reduce it to a minimal set of code that invokes the problem.. like only a few writes or something
2014-01-20T21:51:19 < bvernoux> ok so no out of order ;)
2014-01-20T21:51:34 < bvernoux> as i'm working more on bigger cortex which are affected by that ;)

2014-01-20T21:51:45 < emeb> jpa-: yeah. something I can test in foreground, not ISR context too.
2014-01-20T21:52:00 < bvernoux> are you sure no IRQ happen ?

2014-01-20T21:57:24 < bvernoux> emeb: try a simple test maybe
2014-01-20T21:57:27 < emeb> and on the next step after the write, all locations get high byte set to FF.

2014-01-20T22:00:38 < bvernoux> anyway only with the real code + elf i could check

2014-01-20T22:03:25 < bvernoux> only basic timer ...
2014-01-20T22:03:34 < jpa-> because it works in sram, it pretty surely works in simulator also
2014-01-20T22:03:35 < bvernoux> but it support the whole instruction set for everything ;)
2014-01-20T22:03:40 < emeb> then how does the simulator tell me anything that just redirecting to SRAM?
2014-01-20T22:03:50 < bvernoux> yes but i want the code with addr in SDRAM
2014-01-20T22:03:56 < bvernoux> the addr can be the source of problem
2014-01-20T22:04:03 < emeb> how's that?
2014-01-20T22:04:20 < bvernoux> if SDRAM is wrong like 0xFFF00000
2014-01-20T22:04:30 < bvernoux> i do not see the addr

2014-01-20T22:05:13 < emeb> Oh, you mean if I got SDRAM_BANK_ADDR set incorrectly?

2014-01-20T22:05:28 < bvernoux> audio_ptr

2014-01-20T22:05:36 < emeb> if that were true then the ST mem test code would fail
2014-01-20T22:05:45 < bvernoux> are you sure you have not enabled DMA
2014-01-20T22:05:59 < bvernoux> or other stuff with your code ...

2014-01-20T22:06:11 < emeb> how does DMA affect SDRAM?
2014-01-20T22:06:28 < bvernoux> if it is badly configured it can write in it
2014-01-20T22:06:35 < bvernoux> or crash some register
2014-01-20T22:06:49 < bvernoux> until a bus error stop it ;)
2014-01-20T22:06:53 < emeb> wouldn't that show up in the ST mem test?
2014-01-20T22:06:56 < bvernoux> it happened for me on LPC4370
2014-01-20T22:07:17 < bvernoux> the dma was buggy and go up to end of memory and stop with bus error but no exception happen on CPU side
2014-01-20T22:07:22 < bvernoux> as the error is on DMA ...
2014-01-20T22:07:50 < bvernoux> maybe on ST mem its faster and you have not the time to see it ;)
2014-01-20T22:08:06 < bvernoux> anyway without the whole code it is really hard to see what's the problem
2014-01-20T22:08:23 < emeb> I am using DMA - that's how the audio data gets in/out of the SRAM buffers I'm using. It seems to be working fine and the SDRAM isn't being corrupted when I run the ST mem test inside the ISR context.
2014-01-20T22:08:44 < bvernoux> ha ok you are using DMA ;)
2014-01-20T22:08:54 < bvernoux> i'm pretty sure it is the source of problems
2014-01-20T22:09:09 < emeb> Thanks! Problem solved!
2014-01-20T22:09:39 < bvernoux> also does the IRQ is reentrant ?
2014-01-20T22:10:00 < bvernoux> as you code could be preempted by an other IRQ with higher priority and trash stuff ...
2014-01-20T22:10:03 < jpa-> emeb: one thing you can try is putting some     for (int i = 0; i < 10; i++) asm("nop");   in the SRAM version to simulate the delay of the sdram accesses
2014-01-20T22:10:30 < bvernoux> also there is some errata
2014-01-20T22:10:37 < bvernoux> in MCU
2014-01-20T22:10:40 < emeb> jpa-: not a bad idea
2014-01-20T22:11:02 < bvernoux> yes sram is way faster
2014-01-20T22:11:05 < emeb> jpa-: I'm going to try to duplicate the error in the foreground context with all the DMA stuff turned off.
2014-01-20T22:11:12 < bvernoux> maybe that happen only after a delay ...
2014-01-20T22:11:16 < jpa-> bvernoux: the errata was discussed earlier and dismissed.. the first one doesn't apply to the version emeb is using, and the read fifo is enabled to work around the second one
2014-01-20T22:11:29 < bvernoux> so just stop DMA behind
2014-01-20T22:11:32 < bvernoux> a minimal code
2014-01-20T22:11:54 < bvernoux> especially driver from ST are not tested and only for demo purpose ...
2014-01-20T22:12:27 < bvernoux> even if maybe now the driver stack is better as before but i'm not confident with their ugly coding practice ;)
2014-01-20T22:12:32 < emeb> The thing that's different about the ST test code and my buffer code is that my buffer code is copying to/from SRAM, while ST code is just writing a computed value likely from a register.
2014-01-20T22:12:54 < emeb> I suspect that there may be an issue when interleaving access to SRAM with access to SDRAM.
2014-01-20T22:12:56 < bvernoux> yes so maybe there is an issue
2014-01-20T22:13:02 < bvernoux> yes refresh issue
2014-01-20T22:13:11 < bvernoux> because of bad SDRAM config
2014-01-20T22:13:21 < bvernoux> ras/cas ... are very sensitive config
2014-01-20T22:13:36 < emeb> so I'll write a small loop to copy to/from SRAM in the foreground with all the background & DMA turned off.
2014-01-20T22:13:45 < bvernoux> yes
2014-01-20T22:14:00 < bvernoux> make a small project and send it ;)
2014-01-20T22:14:06 < bvernoux> i have the hw to test it
2014-01-20T22:14:13 < bvernoux> it is funny to debug such stuff
2014-01-20T22:14:28 < emeb> yes, it's a brain teaser.
2014-01-20T22:14:49 < bvernoux> have you also a timer behind ?
2014-01-20T22:15:22 < bvernoux> a must is also to check cycl count
2014-01-20T22:15:38 < bvernoux> to check theory vs practice
2014-01-20T22:18:37 < emeb> cycle counts are enabled
2014-01-20T22:18:50 < bvernoux> great
2014-01-20T22:19:10 < bvernoux> as in fact DMA are not in priotiy on BUS
2014-01-20T22:19:17 < bvernoux> CPU take the control as master
2014-01-20T22:19:39 < bvernoux> and if you want to write same area as DMA CPU will win and DMA will run when no access with CPU
2014-01-20T22:20:51 < bvernoux> it is also very important to use other Bank area for DAM than the one used for CPU code, data
2014-01-20T22:20:57 < bvernoux> else DMA is delayed ...
2014-01-20T22:21:53 < bvernoux> this architecture is not well explained in documentation ...

2014-01-20T22:25:40 < bvernoux> the hint is to download demo and update it
2014-01-20T22:25:48 < bvernoux> and you will have all the features
2014-01-20T22:27:19 < bvernoux> it also generate bery good disassembly listing not like GCC buggy C/ASM mixed code

2014-01-21T01:03:54 < emeb> well...... taking the SDRAM accesses outside of ISR context didn't help
2014-01-21T01:04:27 < emeb> now the audio that is run through the buffer is still corrupted, but the memory tests run simultaneously still pass. :P
2014-01-21T01:05:00 < emeb> the only difference seems to be the pattern of memory accesses.

2014-01-21T08:51:08 < emeb_mac> ya
2014-01-21T08:55:18 < ds2> what sdram problem?
2014-01-21T08:55:47 < emeb_mac> having some very strange issues trying to use the sdram on the f429 discovery board.
2014-01-21T08:59:59 < ds2> how much DRAM is on there?
2014-01-21T09:00:09 < emeb_mac> 8MB

2014-01-21T09:10:06 < ds2> oooh enough for uCLinux
2014-01-21T09:11:39 < zyp> emeb_mac, I saw you mentioned it had the same behavior outside interrupt context
2014-01-21T09:11:52 < emeb_mac> zyp: yes
2014-01-21T09:12:14 < zyp> hmm
2014-01-21T09:12:24 < zyp> is the problem consistent?
2014-01-21T09:12:33 < emeb_mac> I've even made it so the memory test and the audio delay use the same buffer code
2014-01-21T09:13:05 < zyp> and it still only happens with the audio delay?
2014-01-21T09:13:07 < emeb_mac> and the audio data gets corrupted but the memory test doesn't
2014-01-21T09:14:07 < zyp> and it still doesn't happen when you point it to sram?
2014-01-21T09:14:15 < emeb_mac> right
2014-01-21T09:14:43 < zyp> hmm
2014-01-21T09:14:55 < zyp> can I see the code?
2014-01-21T09:15:11 < emeb_mac> sure
2014-01-21T09:15:56 < emeb_mac> you want just pastebin of problem area or the whole project
2014-01-21T09:16:00 < jpa-> emeb_mac: do you still have DMA in the system or did you eliminate that too?
2014-01-21T09:16:05 < jpa-> whole project :)
2014-01-21T09:16:10 < zyp> pastebin of problem area should do for now
2014-01-21T09:16:16 < emeb_mac> jpa-: DMA is still running
2014-01-21T09:16:29 < zyp> I'd test it here, but I'm at work now
2014-01-21T09:16:43 < jpa-> emeb_mac: are you absolutely sure that DMA is not catching up with your for-loop or anything?
2014-01-21T09:17:03 < zyp> that's a good point
2014-01-21T09:17:09 < emeb_mac> jpa-: yes - the DMA buffers are out of the picture.
2014-01-21T09:17:16 < zyp> remember that sdram is slower than sram
2014-01-21T09:17:23 < jpa-> emeb_mac: and DMA is stopped while the buffer code runs?
2014-01-21T09:17:55 < emeb_mac> I'm copying from the dma buffer to an SRAM buffer then running the SRAM buffer through SDRAM, back to SRAM and back to DMA
2014-01-21T09:18:26 < emeb_mac> and the whole process is triggered by a flag that's set in the DMA ISR, but runs in foreground
2014-01-21T09:18:46 < emeb_mac> so if the DMA buffers change it won't affect the data I'm working on.
2014-01-21T09:19:07 < jpa-> i would still try to eliminate the DMA
2014-01-21T09:19:52 < jpa-> step 1) instead of reading from DMA buffer, just write some test data there that is in the value range of the audio       step 2) disable DMA
2014-01-21T09:20:03 < emeb_mac> yeah
2014-01-21T09:20:43 < emeb_mac> I'm doing that now - the memory test and the audio delay are running sequentially, both to SDRAM
2014-01-21T09:21:06 < emeb_mac> the memory test passes (and I'm loading it with PRN data that changes every time)
2014-01-21T09:21:20 < emeb_mac> the audio gets corrupted.
2014-01-21T09:21:39 < emeb_mac> and both use the same buffer code.
2014-01-21T09:21:58 < jpa-> same as in same function, or same as in copypasted?
2014-01-21T09:22:04 < emeb_mac> same function
2014-01-21T09:22:14 < jpa-> ok
2014-01-21T09:22:21 < zyp> tried with -O0 again?
2014-01-21T09:22:31 < emeb_mac> already using -O0
2014-01-21T09:22:35 < zyp> ok
2014-01-21T09:22:40 < jpa-> shouldn't be any compiler funniness going on, as it won't even inline
2014-01-21T09:22:45 < emeb_mac> right
2014-01-21T09:24:47 < emeb_mac> here's the project: https://dl.dropboxusercontent.com/u/17017364/F429_Discovery_SAI.zip
2014-01-21T09:27:12 < emeb_mac> here's the SDRAM access routine: http://pastebin.com/C5gWRLmJ
2014-01-21T09:28:45 < emeb_mac> here's how it's called from the memtest: http://pastebin.com/ZKXPsTJA
2014-01-21T09:29:42 < jpa-> uhhh... wtf is going on with audio_ptr?
2014-01-21T09:30:08 < emeb_mac> here's how it's called from the audio processing loop: http://pastebin.com/EXXgMS68
2014-01-21T09:30:43 < emeb_mac> where do you see audio_ptr used?
2014-01-21T09:31:18 < emeb_mac> that code should be disabled by preprocessor
2014-01-21T09:31:28 < jpa-> ah no, indeed it is not used :)
2014-01-21T09:31:53 < jpa-> i was remembering parts of the code i saw yesterday :P
2014-01-21T09:32:23 < emeb_mac> yeah - that's long gone. :)
2014-01-21T09:36:17 < jpa-> still pretty much code.. but cannot spot anything that could explain it
2014-01-21T09:37:06 < emeb_mac> yeah.
2014-01-21T09:37:24 < emeb_mac> sounds like the next thing to try is eliminating DMA
2014-01-21T09:37:37 < jpa-> in fact, it's so strange that i cannot really figure how a hardware problem could explain it either, unless it is some very crazy conflict
2014-01-21T09:37:49 < emeb_mac> right
2014-01-21T09:37:55 < emeb_mac> it's baffling
2014-01-21T09:38:19 < jpa-> how do you detect the problem with audio?
2014-01-21T09:38:22 < emeb_mac> I was thinking some sort of cache issue, but the memtest should have shown that too
2014-01-21T09:38:29 < emeb_mac> jpa-: listening.
2014-01-21T09:38:37 < jpa-> ok
2014-01-21T09:38:42 < zyp> hmm
2014-01-21T09:38:45 < emeb_mac> I put a sinewave through - it gets ratty
2014-01-21T09:38:58 < emeb_mac> also, it doesn't delay
2014-01-21T09:39:02 < zyp> so SDRAM_delay is the only function accessing the sdram
2014-01-21T09:39:10 < emeb_mac> yes
2014-01-21T09:39:14 < zyp> http://paste.jvnv.net/view/kgWTi <- I built and disassembled it
2014-01-21T09:40:36 < emeb_mac> hard to make much of that
2014-01-21T09:41:18 < zyp> uh, I'm not sure wtf is going on there
2014-01-21T09:41:35 < jpa-> it's unoptimized code
2014-01-21T09:41:50 < jpa-> that's why it's totally bloated and hard to comprehend :P
2014-01-21T09:41:51 < zyp> yes
2014-01-21T09:42:04 < jpa-> like dumping r3 on the stack all the time
2014-01-21T09:42:04 < zyp> fair enough
2014-01-21T09:42:41 < zyp> hang on, let me read through this a bit
2014-01-21T09:45:13 < jpa-> too bad i don't have F429 :P
2014-01-21T09:45:43 < emeb_mac> you need moar devboards!
2014-01-21T09:46:03 < zyp> wtf, -O2 makes that function larger
2014-01-21T09:46:12 < jpa-> starts unrolling, probably
2014-01-21T09:46:25 < jpa-> -Os is usually the nicest to read for a human being :P
2014-01-21T09:47:15 < emeb_mac> sorta makes sense
2014-01-21T09:47:18 < zyp> true
2014-01-21T09:47:42 < emeb_mac> just see it loading pointers, storing data at offsets, incrementing pointers
2014-01-21T09:47:54 < zyp> -Os still looks weird though
2014-01-21T09:48:08 < emeb_mac> just looks like basic ldrh & strh operations to the SDRAM
2014-01-21T09:48:10 < jpa-> emeb_mac: i would try making the audio test automatic also, for example do the same thing with sram in parallel and compare results - then you can breakpoint where the compare fails
2014-01-21T09:48:22 < emeb_mac> jpa-: yes
2014-01-21T09:48:31 < emeb_mac> also on the todo list
2014-01-21T09:48:40 < jpa-> you have a lot of stuff to try ;)
2014-01-21T09:48:47 < emeb_mac> yep
2014-01-21T09:48:53 < emeb_mac> things to do later
2014-01-21T09:48:59 < emeb_mac> getting close to bedtime here

2014-01-21T21:12:25 < englishman> hey guys has anyone here used vcp on f3
2014-01-21T21:12:45 < englishman> i got it working, but when i disconnect, usbIsConfigured usbIsConnected stay true
2014-01-21T21:15:31 < zyp> I don't know vcp code, but the f3 usb core itself has no way to tell that a disconnect has happened
2014-01-21T21:15:38 < englishman> hm, ok
2014-01-21T21:16:07 < zyp> because the usb core doesn't use vbus, and vbus being removed is how you detect a disconnect
2014-01-21T21:16:37 < zyp> you should see a suspend event though, since it stops getting SOF packets
2014-01-21T21:16:53 -!- FreezingCold [~FreezingC@135.0.41.14] has joined ##stm32
2014-01-21T21:17:42 < englishman> so in my circuit i should detect vbus and take action that way
2014-01-21T21:17:50 < englishman> using discoveryf3 right now
2014-01-21T21:18:14 < zyp> either that or check for a suspend instead of a disconnect
2014-01-21T21:19:08 < zyp> I believe vbus on the f3discovery is hardwired to the vbus on the stlink port, so it will always be powered
2014-01-21T21:19:17 < zyp> unless it has diodes, I might remember wrong
2014-01-21T21:19:27 -!- DanielHolth [~dholth@ip98-180-40-196.ga.at.cox.net] has joined ##stm32
2014-01-21T21:19:45 < zyp> ah, it has diodes
2014-01-21T21:21:10 < bvernoux> a nice patch to avoid using USB VBUS sense ;)
2014-01-21T21:21:10 < bvernoux>   #define GCCFG_NOVBUSSENS (1U<<21)
2014-01-21T21:21:10 < bvernoux>   stm32_otg_t *otgp = (&USBD1)->otg;
2014-01-21T21:21:10 < bvernoux>   otgp->GCCFG |= GCCFG_NOVBUSSENS;
2014-01-21T21:21:29 < bvernoux> it works fine here and avoid to loose an additional GPIO ;)
2014-01-21T21:21:45 < zyp> did you read anything he wrote at all?
2014-01-21T21:22:02 < bvernoux> yes it is to detect disconnect ;)
2014-01-21T21:22:08 < zyp> he's using f3, you're talking about f4
2014-01-21T21:22:15 < bvernoux> i think it is same on f3
2014-01-21T21:22:18 < zyp> they are using completely different usb cores
2014-01-21T21:22:20 < bvernoux> USB are very similar
2014-01-21T21:22:23 < bvernoux> ha
2014-01-21T21:22:39 < bvernoux> so it is for other which are interested in the hint for F4 ;)
2014-01-21T21:23:00 < zyp> well, you're not addressing the problem either
2014-01-21T21:23:14 < zyp> what he wanted was vbus sensing, which doesn't even exist on f3
2014-01-21T21:23:20 < bvernoux> yep ;)
2014-01-21T21:23:28 < zyp> and what you're talking about is removing vbus sensing, not adding it.
2014-01-21T21:23:55 < bvernoux> Yes i know it is just about USB not related to his problem
2014-01-21T21:25:08 < bvernoux> does anyone have tested SPI1 + SDC at same time ?
2014-01-21T21:25:20 < bvernoux> as I have an issue with it under chibios
2014-01-21T21:25:27 < bvernoux> on F4
2014-01-21T21:25:45 < zyp> sdc?
2014-01-21T21:25:46 < bvernoux> when SPI1 is configured with DMA SDC stop working
2014-01-21T21:25:49 < bvernoux> SDcard
2014-01-21T21:25:53 < zyp> ah, SDIO
2014-01-21T21:25:56 < bvernoux> ys SDIO
2014-01-21T21:26:04 < bvernoux> in SD mode 4bits native
2014-01-21T21:26:14 < zyp> there is a note about that in the errata, have you read it?
2014-01-21T21:26:23 < bvernoux> ha really ?
2014-01-21T21:26:30 < bvernoux> i have not read that about SDIO + SPI1
2014-01-21T21:26:35 < bvernoux> or maybe DMA ?
2014-01-21T21:26:49 < bvernoux> let me check again
2014-01-21T21:26:59 < zyp> it's something about DMA and FIFO-peripherals, which includes SDIO if I remember correctly
2014-01-21T21:27:13 < zyp> might not be relevant, but worth checking
2014-01-21T21:27:18 < bvernoux> yes
2014-01-21T21:27:26 < zyp> are you only using DMA for SDIO, or also for SPI?
2014-01-21T21:27:45 < bvernoux> god question i have not checked if chibios SDIO code use DMA
2014-01-21T21:27:47 < bvernoux> SPI use it
2014-01-21T21:28:07 < Steffanx> doesn't chibios use dma for almost everything?
2014-01-21T21:28:13 < bvernoux> it should
2014-01-21T21:28:29 < zyp> I think SDIO is kinda useless without DMA, it's designed for DMA
2014-01-21T21:28:30 < bvernoux> UART and SPI use DMA
2014-01-21T21:28:43 < bvernoux> Yes i think SDIO is used with DMA too
2014-01-21T21:28:46 < bvernoux> i will check it
2014-01-21T21:28:54 < bvernoux> i'm using the last version trunk
2014-01-21T21:31:00 < zyp> doesn't look like it's related after all
2014-01-21T21:31:12 < zyp> it mainly applies to DCMI and FSMC
2014-01-21T21:31:13 < bvernoux> yes it use DMA
2014-01-21T21:31:27 < bvernoux> yes it is what i read
2014-01-21T21:31:46 < bvernoux> and i do not use DCMI or FSMC and they are not available on STM32F405RGT LQFP64 version
2014-01-21T21:32:17 < bvernoux> anyway it could be a bug / conflict with DMA stream too
2014-01-21T21:32:24 < bvernoux> or even a bug somewhere in my code ...
2014-01-21T21:32:25 -!- amstan [~alex@aichallenge/admin/amstan] has joined ##stm32
2014-01-21T21:32:53 < bvernoux> it is true they are using SDIO->FIFO for dma
2014-01-21T21:32:58 < bvernoux> but there is no other choice
2014-01-21T21:33:02 < englishman> hmm, why would breakpoints be unavilable in some files?
2014-01-21T21:33:19 -!- CRF_Peter [~Peter@h-154-110.a370.priv.bahnhof.se] has quit [Ping timeout: 272 seconds]
2014-01-21T21:33:26 < bvernoux> englishman: use -g2 not -g3 and not -o3
2014-01-21T21:33:48 < zyp> englishman, unavailable how?
2014-01-21T21:33:51 < englishman> yeah its -o0
2014-01-21T21:33:52 < bvernoux> englishman: -g3 bug with lot of debugger and -o3 have not enough symbol for debug ...
2014-01-21T21:33:56 < englishman> what's -g3?
2014-01-21T21:34:15 < zyp> debug symbols, level 3
2014-01-21T21:35:06 < englishman> oh is that gcc?
2014-01-21T21:35:06 < bvernoux> in theory -g3 should add more symbol to see more stuff during debug ;)
2014-01-21T21:35:16 < bvernoux> but anyway avoid it ;)
2014-01-21T21:35:21 < zyp> englishman, yes, CFLAGS
2014-01-21T21:35:26 < englishman> yeah i'm using keil
2014-01-21T21:35:33 < zyp> ah
2014-01-21T21:35:43 < zyp> then I know nothing :)
2014-01-21T21:36:06 < bvernoux> Level 3 includes extra information, such as all the macro definitions present in the program. Some debuggers support macro expansion when you use -g3.
2014-01-21T21:36:29 < englishman> hmmmm, looks like there is a setting in usb_conf.h that enables/disables suspend/resume
2014-01-21T21:36:49 < bvernoux> anyone have tested latest GNU ARM embedded ?
2014-01-21T21:36:59 < bvernoux> I have discovered strange stuff with it
2014-01-21T21:37:10 < bvernoux> it is q4 version
2014-01-21T21:38:21 < bvernoux> 4.8-2013-q4-major
2014-01-21T21:38:47 < bvernoux> I will test it again with stable code to check ;)
2014-01-21T21:39:02 < bvernoux> especially to check lib-nano 2.0
2014-01-21T21:39:33 < bvernoux> also this feature seems cool
2014-01-21T21:39:33 < bvernoux> * A new compiler option -mslow-flash-data to minimize the literal load to
2014-01-21T21:39:33 < bvernoux>   boost performance for some armv7-m targets.
2014-01-21T21:40:43 < zyp> will only matter on chips with slow flash
2014-01-21T21:41:05 < zyp> on f4 it will probably have no advantage
2014-01-21T21:41:14 < bvernoux> on f4 there is case where it is slow ;)
2014-01-21T21:41:20 < bvernoux> the cache is not huge IIRC 256bytes
2014-01-21T21:41:40 < bvernoux> so any big jump out of preloaded data is very slow
2014-01-21T21:42:39 < bvernoux> as internal flash is 6 wait states IIRC @ 168MHz
2014-01-21T21:43:06 < bvernoux> 5 waitstates in fact
2014-01-21T21:43:14 < zyp> the data cache is 8 lines of 16 bytes each
2014-01-21T21:43:27 < zyp> the code cache is 64 lines, but not relevant for literal loads
2014-01-21T21:43:36 < bvernoux> ha yes 128bytes not 256 ;)
2014-01-21T21:43:44 < zyp> so?
2014-01-21T21:44:22 < zyp> the literal pool is located at the end of the function, once you've loaded the first literal, you have the entire cache line with the rest of them in the cache
2014-01-21T21:44:48 < bvernoux> yes except when you branch
2014-01-21T21:45:34 < zyp> branches inside a function doesn't matter, the literal pool is always at the end anyway
2014-01-21T21:46:03 < bvernoux> anyway it is really better than LPC43xxx with SPIFI which runs at about 30MHz by default and only with 4bits ;)
2014-01-21T21:46:21 -!- ntfreak_ is now known as ntfreak
2014-01-21T21:46:24 < zyp> yes
2014-01-21T21:46:46 < bvernoux> but i will add loading code in SRAM for F4
2014-01-21T21:46:55 < bvernoux> especially for hard realtime stuff
2014-01-21T21:47:13 < zyp> like all ISRs?
2014-01-21T21:47:29 < bvernoux> yes or just ultra fast stuff
2014-01-21T21:47:39 < bvernoux> like NFC demodulation in realtime
2014-01-21T21:48:04 < bvernoux> I'm pretty sure my code could run with 13.56Mhz data input ;)
2014-01-21T21:48:19 < bvernoux> it run fine with 4Mhz input ;)
2014-01-21T21:48:49 < bvernoux> using SPI slave + DMA cyclic double buffer mode ;)

2014-01-21T21:49:07 < bvernoux> with SPI CLK on NFC clock ;)
2014-01-21T21:49:27 < bvernoux> I will publish the code it is very funny to use ARM tricks
2014-01-21T21:50:24 < bvernoux> using CLZ asm instruction for stream synchro is a very nice feature
2014-01-21T21:51:08 < bvernoux> without that instruction i could not stream in realtime 4MHz
2014-01-21T21:52:15 < bvernoux> 4Mhz is 3.39Mhz of course => 13.56/4
2014-01-21T21:52:54 < bvernoux> as the bitstream max speed is 848KHz

2014-01-21T22:20:18 < karlp> bvernoux: really, what toolchains ar eyou working with that "fail" with -g3?
2014-01-21T22:22:35 < bvernoux> karlp: the problem was with LPCXpresso not supporting -g3 in fact
2014-01-21T22:22:55 < bvernoux> karlp: anyway it is not recommended to use -g3
2014-01-21T22:23:00  * karlp slaps bvernoux 
2014-01-21T22:23:13 < bvernoux> i'm using q3 version
2014-01-21T22:23:24 < karlp> the expresso is a hardware board, what tools were you using that were unable to deal with -g3 elfs?
2014-01-21T22:23:58 < bvernoux> LPCXpresso is not a board it is the NXP software to debug LPC
2014-01-21T22:24:09 < bvernoux> especially multicore
2014-01-21T22:24:09 < bvernoux> LPCXpresso v6.1.2_177
2014-01-21T22:24:25 < bvernoux> also it work with LPC Link2 debugging 2 core at same time ;)
2014-01-21T22:26:08 < karlp> so explain clearly what your problems are with -g3 before you go making blanke remarks like "not recommended to use -g3"
2014-01-21T22:27:58 < bvernoux> with LPCxpresso you cannot debug at all
2014-01-21T22:28:05 < bvernoux> breakpoint are in worng place
2014-01-21T22:28:08 < bvernoux> wrong
2014-01-21T22:28:17 < bvernoux> and that even crash the MCU
2014-01-21T22:28:34 < bvernoux> I imagine behind debug info are not decoded correctly for -g3
2014-01-21T22:28:47 < zyp> I imagine you might be wrong
2014-01-21T22:28:57 < bvernoux> ?
2014-01-21T22:29:01 < zyp> :)
2014-01-21T22:29:15 < bvernoux> It was a total headach to understand that ;)
2014-01-21T22:29:31 < bvernoux> when i changed option and code at same time i was thinking it was new code bug ... ;)
2014-01-21T22:29:34 < qyx_> it was quite simple sentence
2014-01-21T22:29:35 < qyx_> ah
2014-01-21T22:29:55 < bvernoux> also -o3 does the same mess
2014-01-21T22:30:04 < bvernoux> with LPCXpresso
2014-01-21T22:30:22 < bvernoux> -o2 or -os is nice with -g2
2014-01-21T22:30:34 < bvernoux> also other like -o0 or -o1 shall work fine
2014-01-21T22:30:38  * karlp slaps bvernoux with the case sensitive stick
2014-01-21T22:31:14 < bvernoux> the problem is there is no other serious/stable tool to debug multicore MCU ;)
2014-01-21T22:31:27 < bvernoux> I do not even speak about tri core on LPC4370
2014-01-21T22:32:00 < karlp> oh man, tri core is an absolute must for serious work! ;)
2014-01-21T22:32:03 < zyp> any optimization level that causes inlining may cause breakpoints to behave a bit weird, because suddenly the source line you're setting a breakpoint on is inlined multiple places in various functions
2014-01-21T22:32:35 < bvernoux> zyp: of course but with -g3 even a breakpoint in main does not work at start ;)
2014-01-21T22:32:39 < bvernoux> and that crash all
2014-01-21T22:32:41 < englishman> ok got it working
2014-01-21T22:32:50 < englishman> borrowed some mods to VCP libs from EvvGC
2014-01-21T22:32:53 < zyp> bvernoux, works fine for me, you're doing something wrong
2014-01-21T22:32:58 < englishman> it detects error interrupt
2014-01-21T22:33:02 < bvernoux> zyp: you are using LPCXpresso ?
2014-01-21T22:33:11 < bvernoux> zyp: i use LPC4370 MCU too
2014-01-21T22:33:17 < zyp> of course not, I'm not using shitty tools
2014-01-21T22:33:19 < bvernoux> zyp: I doubt you tested it
2014-01-21T22:33:40 < bvernoux> it is not cheaty when you know how to use it ;)
2014-01-21T22:33:51 < bvernoux> the hint is NEVER try debugging M4F with JTAG ;)
2014-01-21T22:33:54 < bvernoux> ONLY SWD
2014-01-21T22:33:56 < zyp> you apparently don't then :)
2014-01-21T22:34:04 < bvernoux> and for M0 or M0s only JTAG work ;)
2014-01-21T22:34:21 < zyp> they still haven't figured out to do multi-drop SWD?
2014-01-21T22:34:25 < zyp> fucking bullshit
2014-01-21T22:34:36 < bvernoux> hmm multi SWD ;)
2014-01-21T22:35:13 < zyp> yes, SWD has a multi-drop extension that lets you have multiple SWDAPs on the same bus
2014-01-21T22:35:35 < bvernoux> anyway M0 and M0s are only JTAG
2014-01-21T22:35:48 < zyp> sure, just like 4350
2014-01-21T22:35:55 < bvernoux> M4F support both JTAG and SWD even if LPCXpresso work only with SWD for M4F
2014-01-21T22:36:06 < bvernoux> yes like 43xx
2014-01-21T22:36:40 < zyp> why do they call one M0 for «coprocessor» and one M0 for «subsystem»?
2014-01-21T22:36:51 < bvernoux> because M0s is on an other bus
2014-01-21T22:36:54 < bvernoux> behind a bridge
2014-01-21T22:37:03 < bvernoux> with direct access to SGPIO 0 wait state ;)
2014-01-21T22:37:18 < bvernoux> and also a special bank SRAM 18KB code/data
2014-01-21T22:37:43 < bvernoux> M0 is not on a bridge
2014-01-21T22:38:03 < bvernoux> and coprocessor because M4F is always the master
2014-01-21T22:38:09 < zyp> 2/16 sounds like a weird split if you're supposed to use one for code and one for data
2014-01-21T22:38:30 < bvernoux> when M4 do access on SRAM shared with M0 the M0 core wait M4 finish access to continue
2014-01-21T22:38:55 < bvernoux> zyp: it is dual bank 16KB code and 2KB data ;)
2014-01-21T22:38:59 < bvernoux> zyp: at full speed
2014-01-21T22:39:12 < zyp> but 2k is pretty small
2014-01-21T22:39:20 < bvernoux> yes but intended for small buffer
2014-01-21T22:39:25 < bvernoux> anyway you have DMA ;)
2014-01-21T22:39:35 < zyp> I guess you're supposed to mainly use it for stack and have everything else in the main memory then
2014-01-21T22:39:47 < bvernoux> yes and use mainly DMA
2014-01-21T22:40:03 < bvernoux> the 2kb are also for multi core commands/answer
2014-01-21T22:40:07 < zyp> what has dma got to do with anything?
2014-01-21T22:40:57 < bvernoux> zyp: just to offload M0 to store data from M0s data to main ram for example
2014-01-21T22:41:04 < zyp> ah, in that sense
2014-01-21T22:41:05 < karlp> speaking of the lpc43xx: http://www.embeddedartists.com/products/app/labtool.php
2014-01-21T22:41:07 < zyp> yes, of course
2014-01-21T22:41:22 < bvernoux> karlp: I have this one ;)
2014-01-21T22:41:42 < bvernoux> karlp: even fixed usb bug on 1st version for win7/8 ;)
2014-01-21T22:42:06 < bvernoux> karlp: actual labtool does use only M4F
2014-01-21T22:42:38 < bvernoux> also for a very nice logic analyzer
2014-01-21T22:42:41 < bvernoux> go to KS
2014-01-21T22:42:45 < bvernoux> DSLogic is very nice
2014-01-21T22:42:47 < bvernoux> for 89USD
2014-01-21T22:43:06 < bvernoux> 256Mbits SDRAM, 16 chan and up to 400MHz IO ;)
2014-01-21T22:43:23 < zyp> I wish there were more cortex-m + fpga options
2014-01-21T22:43:46 < bvernoux> zyp: Yes i dream about that too a part with 8kcells FPGA in LPC ;)
2014-01-21T22:44:21 < bvernoux> zyp: or Cortex R7F ;)
2014-01-21T22:44:32 < bvernoux> in small package
2014-01-21T22:45:11 < bvernoux> also an amazing multicore
2014-01-21T22:45:12 < bvernoux> http://www.kalray.eu/products/mppa-manycore/mppa-256/
2014-01-21T22:45:17 < bvernoux> made in France ;)
2014-01-21T22:45:22 < zyp> nah, I don't need much cpu power, I just want to be able to do custom hardware interfaces
2014-01-21T22:45:24 < bvernoux> by some ST guys
2014-01-21T22:46:11 < bvernoux> zyp: yes for custom instruction will be nice
2014-01-21T22:46:24 < bvernoux> or custom hardware glue logic
2014-01-21T22:46:35 < bvernoux> like interfacing 12 or 16bits fast ADC
2014-01-21T22:46:39 < zyp> I don't want custom instructions, I want configurable silicon with access to an AHB master port
2014-01-21T22:46:45 < bvernoux> we just have no any MCU for that :(
2014-01-21T22:46:53 < zyp> well, there is smartfusion
2014-01-21T22:46:56 < bvernoux> SGPIO are too limited for ADC => only 8bits :(
2014-01-21T22:47:26 < bvernoux> zyp: I want the both => specialized instructions + bus ;)
2014-01-21T22:47:48 < bvernoux> zyp: zynq7020 is very nice for such feature
2014-01-21T22:48:03 < zyp> zynq is too large and expensive for what I want to do
2014-01-21T22:48:04 < bvernoux> i'm waiting my paralllella board ...
2014-01-21T22:48:09 < zyp> so am I
2014-01-21T22:48:18 < bvernoux> yes zynq have no small package :(
2014-01-21T22:48:31 < bvernoux> like BGA256 1mm ball ;)
2014-01-21T22:48:38 < karlp> zyp: isn't licensing some of the problem for doing cortex m1 stuff?
2014-01-21T22:49:10 < karlp> I thought I saw a cheap hard m1 the other day, but can't find it now
2014-01-21T22:49:11 < bvernoux> i have never see any M1 with FPGA logic
2014-01-21T22:49:15 < zyp> I haven't looked much at cortex-m1
2014-01-21T22:49:31 < zyp> because I expect it to be insanely expensive
2014-01-21T22:49:38 < bvernoux> yes it is ultra specialized
2014-01-21T22:49:51 < bvernoux> and i imagine they do not sell it very well
2014-01-21T22:50:00 < zyp> bvernoux, m1 is targetted specifically for fpga, as a softcore
2014-01-21T22:50:22 < zyp> that's why there is no chips with m1, you just put it in a plain fpga yourself
2014-01-21T22:50:26 < bvernoux> zyp: IIRC M1 is an hybrid M0 core + FPGA logic
2014-01-21T22:50:37 < zyp> no
2014-01-21T22:50:40 < bvernoux> ha ok
2014-01-21T22:51:17 < karlp> yeah, microsemi igloo/e (m1) starts at $90
2014-01-21T22:51:27 < bvernoux> karlp: too expensive ;)

2014-01-21T22:51:35 < karlp> yeah, smartfusion is cheaper
2014-01-21T22:51:48 < bvernoux> FPGA are mainly too expensive and missing MCU inside and softcore are too slow and use all cells ...
2014-01-21T22:52:09 < karlp> well, cheapest smartfusion on digikey is only $17...
2014-01-21T22:52:18 < bvernoux> ha
2014-01-21T22:52:46 < karlp> not entirely unreasonable
2014-01-21T22:52:56 < zyp> hmm, I think the main problem I have with smartfusion is that there's no cheap devboards
2014-01-21T22:53:10 < zyp> and I don't want to start by designing a board, before having any experience with the chip
2014-01-21T22:53:12 < bvernoux> ha there an M3 hard core in it
2014-01-21T22:53:53 < bvernoux> Buy a SmartFusion Evaluation Kit for only $99
2014-01-21T22:53:54 < karlp> bvernoux: that's why we mentioned it dummy
2014-01-21T22:53:59 < zyp> there's a $99 evalkit, but that doesn't have enough free IO to prototype my shit with
2014-01-21T22:54:04 < bvernoux> ha i have never see this stuff
2014-01-21T22:54:19 < karlp> so listen sometimes :)
2014-01-21T22:54:38 < bvernoux> does FPGA is linked to M3 core ?
2014-01-21T22:54:41 < zyp> the smartfusion2 starter kit might work
2014-01-21T22:54:49 < zyp> yes
2014-01-21T22:54:55 < bvernoux> like adding easily custom instruction and use them using ARM special instruction copro
2014-01-21T22:54:57 < bvernoux> ?
2014-01-21T22:55:08 < zyp> smartfusion provides both master and slave ports towards the AHB matrix
2014-01-21T22:55:24 < zyp> dunno about instructions, I'm not interested in that so I didn't check
2014-01-21T22:55:50 < zyp> why would I make a custom instruction for anything when I can just make a memory mapped register instead?
2014-01-21T22:55:56 < bvernoux> nice SmartFusion2
2014-01-21T22:56:12 < bvernoux> zyp: custom instruction can be faster ;)

2014-01-21T22:56:58 < zyp> in your dreams
2014-01-21T22:56:58 < bvernoux> like doing instruction like in PS3 SPE
2014-01-21T22:57:17 < bvernoux> the architecture was very nice and never really used
2014-01-21T22:57:37 < bvernoux> the SPE even today it totally amazing
2014-01-21T22:58:46 < bvernoux> woo i like SmartFusion2 low power features
2014-01-21T22:58:52 < bvernoux> very nice
2014-01-21T22:59:01 < bvernoux> does anyone tested it in real life ?
2014-01-21T22:59:06 < karlp> proasic3 has m1 available too,
2014-01-21T22:59:16 < karlp> $18 and actually _stocked_ at digikey
2014-01-21T22:59:23 < zyp> no, because the kit is too expensive to buy as a toy
2014-01-21T22:59:23 < bvernoux> with solderable package ?
2014-01-21T22:59:27 < bvernoux> not BGA484 ?
2014-01-21T22:59:37 < karlp> 100qfp :)
2014-01-21T22:59:40 < bvernoux> woo nice
2014-01-21T23:00:10 < zyp> karlp, sure that's not a proasic3 nano?
2014-01-21T23:00:34 < bvernoux> StarterKit 625USD ;)
2014-01-21T23:00:49 < karlp> well, part numbers were the same,
2014-01-21T23:00:53 < karlp> but no, not 100% sure
2014-01-21T23:01:04 < zyp> ah, proasic3l is also available in 100qfp
2014-01-21T23:01:18 < karlp> just starting on microsemi's sit eand browsing the other categories, they offer m1 soft in a few of their cores
2014-01-21T23:01:26 < karlp> and m3 hard in some of the /e things or something
2014-01-21T23:01:34  * karlp is rather out of his depth on this though :)
2014-01-21T23:02:01 < zyp> anyway, the problem with going full fpga with m1 is that you have to deal with the rest of the peripherals too
2014-01-21T23:02:14 < karlp> I was looking more at getting one of these to play with: http://www.latticesemi.com/en/Products/DevelopmentBoardsAndKits/iCEstick.aspx
2014-01-21T23:02:16 < zyp> and fpgas doesn't tend to have much sram/flash :p
2014-01-21T23:02:27 < karlp> the ice40 is only in the $2-3 in singles
2014-01-21T23:02:50 < zyp> is it volatile?
2014-01-21T23:03:39 < zyp> oh well
2014-01-21T23:04:03 < karlp> no, ice40 is non-volatiile
2014-01-21T23:04:32 < karlp> but yeah, I have no project that _needs_ this, and no experience with them whatsoever :)
2014-01-21T23:04:53 < zyp> I'm currently planning to make a spartan-3a board which fits the fsmc headers on the waveshare stm32 board I have, I think I concluded that seemed the most sane way for what I want to do
2014-01-21T23:05:40 < zyp> the disadvantage is that I can't do DMA that way, but I don't think I really need to
2014-01-21T23:06:56 < bvernoux> what you want to do ?
2014-01-21T23:07:02 < karlp> profit!
2014-01-21T23:07:39 < bvernoux> zyp: jump to lpc4370 + sgpio if you want to communicate with external stuff at very high speed
2014-01-21T23:07:49 < bvernoux> the price is ultra low

2014-01-21T23:08:27 < bvernoux> I think 80MHz and maybe 100MHz could be reached with SGPIO 8bits ;)
2014-01-21T23:08:33 < zyp> bvernoux, I want to interface with a 16 bit wide bus, as a slave :)
2014-01-21T23:08:37 < bvernoux> 100MB/s is not bad for a MCU @200MHz
2014-01-21T23:08:53 < bvernoux> why not using SDRAM ?
2014-01-21T23:09:03 < bvernoux> it is 16bits
2014-01-21T23:09:06 < zyp> for what?
2014-01-21T23:09:08 < zyp> uh
2014-01-21T23:09:10 < bvernoux> SDRAM port
2014-01-21T23:09:21 < zyp> the bus is already there, defined and all
2014-01-21T23:09:24 < bvernoux> LPC runs up to 200MHz on SDRAM ;)
2014-01-21T23:09:44 < zyp> I want to interface with it, receive packets from it, process them, and return packets when it asks me for them
2014-01-21T23:09:46 < bvernoux> very stable at 166Mhz in fact
2014-01-21T23:09:50 < bvernoux> 200Mhz is very tricky
2014-01-21T23:10:15 < zyp> and I don't give a fuck about SDRAM, the packets won't be that large.
2014-01-21T23:10:45 < bvernoux> you can do the trick with it

2014-01-21T23:11:13 < bvernoux> FPGA act as SDRAM and send you signal to ask LPC to send data or do stuff ;)
2014-01-21T23:11:33 < zyp> …
2014-01-21T23:11:51 < bvernoux> even an STM32 could do the trick with SDRAM controller even at 80MHz it is very nice
2014-01-21T23:12:24 < zyp> why the fuck does SDRAM controller matter when there's no actual SDRAM involved? it's in no way faster than the plain SRAM controlle
2014-01-21T23:12:39 < zyp> and that's what I already said I'm planning to use
2014-01-21T23:12:44 < bvernoux> SDRAM will be just to use the bus ;)
2014-01-21T23:12:53 < bvernoux> behind on FPGA side you can do other stuff
2014-01-21T23:13:00 < bvernoux> ha ok
2014-01-21T23:13:22 < bvernoux> what FPGA you will use ?
2014-01-21T23:13:27 < bvernoux> ProAsic3 or other ?
2014-01-21T23:13:45 < zyp> emeb suggested spartan-3a, it looks like a nice fit
2014-01-21T23:14:05 < zyp> enough blockram to buffer what it needs to buffer, I believe
2014-01-21T23:14:21 < bvernoux> spartan6lx is very nice too ;)
2014-01-21T23:14:30 < zyp> and I've already used xilinx tools before, so I'm prepared for how shitty they are
2014-01-21T23:14:59 < bvernoux> hehe
2014-01-21T23:15:22 < emeb> yay FPGA
2014-01-21T23:15:35 < bvernoux> anyway at end FPGA is the way to go
2014-01-21T23:15:52 < bvernoux> even if that increase dvelopment time by a big factor compared to MCU
2014-01-21T23:17:29 < zyp> emeb, just you wait, I'm gonna ask you for hints and help when I find time to start designing the board ;)
2014-01-21T23:17:46 < emeb> zyp: no problem. should be fun.
2014-01-21T23:22:20 < bvernoux> cool SmartFusion2 have new package
2014-01-21T23:22:24 < bvernoux> VQ144 !!
2014-01-21T23:22:34 < bvernoux> and VF256

2014-01-21T23:23:54 < karlp> zyp: any beginner tips on writing the descriptors for compound usb devices?
2014-01-21T23:25:25 < zyp> what kind, what os?
2014-01-21T23:25:59 < karlp> usbtmc+cdcacm for stm32f4
2014-01-21T23:26:09 < karlp> linux + windows I guess
2014-01-21T23:26:12 < zyp> first you want to figure out whether you want IAD or not, you want IAD if you want to do ACM on windows
2014-01-21T23:26:35 < zyp> hmm
2014-01-21T23:26:36 < zyp> anyway
2014-01-21T23:26:50 < zyp> without IAD, making a compound device is easy
2014-01-21T23:27:05 < zyp> you just set the device class to «specified in interface»
2014-01-21T23:27:18 < zyp> and then you just add all the interfaces you need, with the appropriate classes
2014-01-21T23:27:33 -!- Viper168_ [~Viper@unaffiliated/viper168] has quit [Ping timeout: 248 seconds]
2014-01-21T23:28:03 < karlp> sounds easy enough :)
2014-01-21T23:28:04 < zyp> IAD is a way to group interfaces, to tell the os (windows mainly) that multiple interfaces should be handled by a single driver, but not the entire device
2014-01-21T23:28:42 < zyp> when you use IAD you set the device class to IAD, and then you add an IAD descriptor before each new group of interface descriptors
2014-01-21T23:29:32 < karlp> and that works for everyone else too right?
2014-01-21T23:29:44 < karlp> so it's a little more complicated to set up, but works in more places?
2014-01-21T23:29:47 < zyp> depends who everyone is
2014-01-21T23:30:01 < zyp> IAD weren't added until OS X 10.7
2014-01-21T23:30:09 < karlp> how long ago is that?
2014-01-21T23:30:19 < zyp> 10.9 came last year
2014-01-21T23:30:42 < zyp> so 10.7 came two and a half year ago or so
2014-01-21T23:30:43 < karlp> osx is probably least concern for me anyway I guess.
2014-01-21T23:30:53 < karlp> yeah, wikipedia says july 2011
2014-01-21T23:30:56 < zyp> yeah, I wouldn't worry
2014-01-21T23:31:16 < zyp> the 10.9 upgrade is free anyway ;)
2014-01-21T23:31:43 < zyp> so the only concern is people stuck on older hardware
2014-01-21T23:32:44 < zyp> are you using libopencm3?
2014-01-21T23:32:52 < karlp> yeah
2014-01-21T23:33:23 < zyp> https://github.com/gsmcmullin/blackmagic/blob/master/src/platforms/stm32/cdcacm.c <- then you should probably look at this
2014-01-21T23:33:31 < zyp> it's a compound device with IAD and all
2014-01-21T23:34:13 < zyp> there are six interfaces IIRC, two CDC pairs, a vendor specific one for trace and the DFU interface
2014-01-21T23:34:20 < zyp> so four IAD groups
2014-01-21T23:34:23 < karlp> do things get upset when endpoitns arne't 80/81?

2014-01-21T23:35:00 < karlp> I guess any sowftware that just goes, "cdcacm? I'm goig to use endpionts 1 and 0x81"
2014-01-21T23:35:07 < karlp> is just dumb and doesn't matter
2014-01-21T23:35:10 < zyp> the upper bit is direction
2014-01-21T23:35:37 < zyp> by the way, which chip?
2014-01-21T23:35:48 < zyp> and which core if f4?
2014-01-21T23:35:59 < karlp> f4 at the moment, because it's disco board has the usb connector, but l1 would be the final target.
2014-01-21T23:36:14 < karlp> so, otg_fs
2014-01-21T23:36:25 < zyp> ok, 0 is always the control endpoint, so that one is reserved
2014-01-21T23:36:35 < zyp> otg_fs only implements 1-3
2014-01-21T23:36:43 < zyp> but l1 would have 1-7
2014-01-21T23:37:05 < zyp> and the corresponding 81-83 vs 81-87 of course
2014-01-21T23:37:14 < karlp> urgh, that may be a problem, cdc-acm needs 2, I think usbtmc needs 3,
2014-01-21T23:37:35 < zyp> yeah, otg_fs doesn't leave much room for compound devices
2014-01-21T23:37:50 < zyp> otg_hs has five instead of three pairs
2014-01-21T23:38:10 < karlp> 3 pairs isn't so bad I guess, but yeah, tight for some things.

2014-01-22T01:59:49 < dongie> i.e. client is connected
2014-01-22T02:00:16 < dongie> does everything send CDC_LINE_CODING ?

2014-01-22T03:10:57 < zyp> dongie, no, CDC_LINE_CODING is only sent when the host needs to specify a baudrate
2014-01-22T03:11:03 < dongie> hm
2014-01-22T03:11:16 < dongie> but doesnt that happen when you open port?
2014-01-22T03:11:22 < dongie> or is there some shit that will open port without sendign that?
2014-01-22T03:11:25 < zyp> there is no explicit function that tells you whether the port is open or not
2014-01-22T03:11:52 < zyp> only the set_configuration call when the device is enumerated and accepted by the driver
2014-01-22T03:12:07 < zyp> oh, and then of course you have usb flow control
2014-01-22T03:12:39 < zyp> if the host is not ready to receive, it should not send IN tokens, and anything you try sending will just sit in the buffer on your side
2014-01-22T03:12:40 < dongie> im getting CNTR_ESOFM wehn I plugin to usb power-only cable
2014-01-22T03:12:52 < dongie> and enable usbd
2014-01-22T03:13:12 < dongie> i'd liek to figure out some graceful way to fix that
2014-01-22T03:14:34 < zyp> you mean ISTR_ESOF
2014-01-22T03:14:43 < zyp> CNTR_ESOFM is the enable for that interrupt
2014-01-22T03:14:51 < dongie> er yeah .
2014-01-22T03:15:17 < zyp> ESOF means that you're not getting SOF packets when they are expected
2014-01-22T03:15:27 < zyp> which is pretty natural when you have no host sending them
2014-01-22T03:15:32 < dongie> right
2014-01-22T03:15:39 < dongie> so what can i do
2014-01-22T03:15:44 < dongie> if I onyl have usb power connected
2014-01-22T03:15:50 < zyp> disable the interrupt?
2014-01-22T03:16:00 < zyp> why do you care?
2014-01-22T03:16:14 < dongie> why do  i care if its on?
2014-01-22T03:16:26 < dongie> i mean if I leave that interrupt the system gets clogged down in spurious interrupts
2014-01-22T03:16:34 < dongie> it never leaves the usb interrupt function

2014-01-22T03:16:50 < zyp> so just clear the CNTR_ESOFM bit
2014-01-22T03:17:48 < zyp> I don't know why it matters, after three missing SOFs the SUSP interrupt will also trigger indicating a suspend condition
2014-01-22T03:18:28 < zyp> but SUSP only triggers once, and is actually useful
2014-01-22T03:18:38 < dongie> hm
2014-01-22T03:19:18 < zyp> dunno what ESOF is good for, maybe you could use it for error logging or something

2014-01-22T08:14:55 < emeb_mac> SDRAM bug found & fixed. F429 seems happy.
2014-01-22T08:19:59 < jpa-> emeb_mac: what was it?
2014-01-22T08:20:19 < emeb_mac> unsurprisingly, me being dumb :P
2014-01-22T08:20:41 < emeb_mac> I always use a GPIO line to indicate when my audio processing routine is active.
2014-01-22T08:20:59 < jpa-> the FLAG_ONE? :)
2014-01-22T08:21:11 < emeb_mac> yep - unfortunately picked a GPIO line that was part of the SDRAM interface.
2014-01-22T08:21:18 < jpa-> :D
2014-01-22T08:21:32 < emeb_mac> so any access to the SDRAM while FLAG_ONE was active would be corrupted
2014-01-22T08:22:17 < jpa-> cute bug
2014-01-22T08:22:18 < emeb_mac> all fixed now. works fine inside the ISR, runs fast w/ -O3

2014-01-22T20:39:10 < karlp> gpio control of the usb pullup would have helped.

2014-01-22T20:55:03 < emeb> it's annoying that they don't include sw control of the pullups in the USB cores.
2014-01-22T20:55:53 < emeb> ISTR that some of the cores actually have that feature, but that the resistance value was outside of the spec limits and so they deprecated the feature / didn't document it.
2014-01-22T20:56:23 < emeb> OR, someone said that it violated a patent, so they didn't document it...
2014-01-22T21:04:32 < zyp> yeah, the spec thing is the problem
2014-01-22T21:04:46 < zyp> it was documented in one of the errata sheets
2014-01-22T21:05:21 < emeb> zyp: did you see I got the SDRAM working?
2014-01-22T21:05:27 < zyp> yep
2014-01-22T21:05:32 < emeb> derp.
2014-01-22T21:05:41 < zyp> I'm a bit curious, how did you manage that?
2014-01-22T21:05:57 < emeb> how did I manage to use the wrong GPIO?
2014-01-22T21:05:58 < zyp> when the pin is in AF, it shouldn't respond to normal writes
2014-01-22T21:06:17 < zyp> so I don't really understand exactly what happened
2014-01-22T21:07:00 < emeb> Good question - I have code in the audio init section to set up the GPIO flag.
2014-01-22T21:07:16 < emeb> if the audio init runs after the SDRAM init then it would override the AF setting.
2014-01-22T21:07:24 < emeb> lemme check the order...
2014-01-22T21:07:30 < zyp> true, but then it'd be broken all the time
2014-01-22T21:07:43 < zyp> unless it happened to be working when it was in your idle state
2014-01-22T21:07:44 < zyp> hmm
2014-01-22T21:07:53 < emeb> yes, but PE1 is a byte lane enable
2014-01-22T21:07:55 < zyp> was it the upper byte enable signal?
2014-01-22T21:07:55 < zyp> ah
2014-01-22T21:08:01 < emeb> and it spends all its time low.
2014-01-22T21:08:37 < emeb> I suppose if I'd been doing 8-bit accesses it might have had different symptoms.
2014-01-22T21:08:55 < zyp> would still be broken every other address
2014-01-22T21:09:54 < emeb> yeah. and the audio init does happen after the sdram init.
2014-01-22T21:10:09 < zyp> ok, then everything makes sense
2014-01-22T21:10:14 < emeb> yup
2014-01-22T21:10:51 < emeb> these things are such fun - so many ways to do it wrong.
2014-01-22T21:10:59 < zyp> :)
2014-01-22T21:11:38 < emeb> next up - for giggles I should make a GUI to control the audio.
2014-01-22T21:12:00 < emeb> put little sliders & buttons on to change the audio effects...
2014-01-22T21:12:06 < zyp> heh
2014-01-22T21:12:30 < zyp> using any gui toolkits?
2014-01-22T21:12:33 < emeb> looks like the ST demo code has a lot of the basic touchscreen & LCD stuff written already.
2014-01-22T21:12:57 < Steffanx> uGFX :P
2014-01-22T21:13:18 < zyp> maybe emeb doesn't want to sell his soul to Tectu
2014-01-22T21:13:23 < zyp> :p
2014-01-22T21:13:30 < emeb> heehee
2014-01-22T21:13:48 < Tectu> no reason to do so.
2014-01-22T21:13:56 < zyp> by the way, how did you hook up the SAI?
2014-01-22T21:14:08 < emeb> what do you mean?
2014-01-22T21:14:15 < zyp> did you get a nice codec chip breakout board or something?
2014-01-22T21:14:54 < emeb> zyp: I built some a while back for FPGA stuff : http://ebrombaugh.studionebula.com/synth/codec_pmod/index.html
2014-01-22T21:15:04 < zyp> ah
2014-01-22T21:15:09 < emeb> just used plug-on flywires between the disco and that.
2014-01-22T21:15:46 < zyp> are you only using the SAI in I2S mode?
2014-01-22T21:16:12 < emeb> F429 brings out enough pins of SAI1 for a full-duplex audio port on PE2-PE6 and they're not used for anything else on the board.
2014-01-22T21:16:25 < emeb> Yes, it's set up for I2S.
2014-01-22T21:16:26 < zyp> I was imagining doing something with more channels :)
2014-01-22T21:16:34 -!- FreezingCold [~FreezingC@205.211.50.161] has joined ##stm32
2014-01-22T21:16:40 < emeb> It's possible to do more
2014-01-22T21:16:59 < Tectu> emeb,  let me know in case of you're using ugfx. I need stuff for the demos site.
2014-01-22T21:17:18 < emeb> the SAI doesn't have a specific "I2S" setting - you have to properly configure the number of channels, frame format, bit offsets & directions.
2014-01-22T21:17:23 < emeb> Tectu: sure!
2014-01-22T21:17:56 < zyp> true
2014-01-22T21:18:16 < emeb> zyp: so it would be cake to do some other format.
2014-01-22T21:18:29 < zyp> yes, I've looked at the documentation
2014-01-22T21:18:52 < zyp> I mean, that's much of the point with the SAI over the old I2S peripherals
2014-01-22T21:19:13 < emeb> I've got another project in the wings that will use both A and B blocks as TX so I can drive 2 I2S dacs.
2014-01-22T21:19:13 < zyp> so I imagined you were playing around with making something with more channels
2014-01-22T21:19:43 < emeb> zyp: not right now, but there are future possibilities.
2014-01-22T21:20:32 < zyp> I still kinda want to make a usb-soundcard with balanced outputs
2014-01-22T21:20:50 < zyp> to hook up to active speakers
2014-01-22T21:20:59 < emeb> zyp: the SAI is nice for I2S in that it doesn't force the bonded ports to have opposite directions.
2014-01-22T21:21:36 < emeb> and of course it doesn't use up SPI ports...
2014-01-22T21:22:15 < emeb> Annnnd - on the Disco pinout those pins were unused on-board.
2014-01-22T21:22:34 < emeb> it's almost like they planned it that way... :)
2014-01-22T21:23:37 < zyp> even if you're not demonstrating a cool new feature, you should not fuck it up for those who want to test it ;)
2014-01-22T21:24:12 < emeb> that's true. what's surprising is that they realized it too.
2014-01-22T21:28:15 < zyp> or just random luck :p

2014-01-22T22:28:35 < Tectu> I know that they use to put several in series, thought
2014-01-22T22:29:02 < GargantuaSauce> all the servers i've torn apart have had centrifugal blowers
2014-01-22T22:29:20 < Tectu> "centrifugal blowers"?
2014-01-22T22:29:20 < GargantuaSauce> that's all 1U though
2014-01-22T22:29:41 < zyp> radial fans
2014-01-22T22:30:01 < zyp> so does my rack stuff too
2014-01-22T22:30:25 < GargantuaSauce> http://i01.i.aliimg.com/wsphoto/v0/1313845595/NMB-6-cm-turbine-font-b-centrifugal-b-font-fan-font-b-blower-b-font-12V.jpg like that
2014-01-22T22:30:28 < GargantuaSauce> they are ridiculously loud
2014-01-22T22:30:34 < Tectu> ah, those
2014-01-22T22:30:45 < Tectu> the 1U blades I've seen all have axial fans
2014-01-22T22:30:48 < Tectu> but like 40mm or something
2014-01-22T22:30:50 < Tectu> even less?
2014-01-22T22:30:56 < Tectu> fuck as loud as well
2014-01-22T22:31:00 < Tectu> loud as fuck*
2014-01-22T22:31:19 < Tectu> 3W turbine, GargantuaSauce :D
2014-01-22T22:31:45 < Lux> Tectu: no not really, it could also be about the alignment of the blades, like one blade shovels the air into the other one running counterclockwise
2014-01-22T22:31:58 < Lux> just a vague theory tough
2014-01-22T22:32:07 < zyp> I used to sleep next to the room where I had my rack stuff
2014-01-22T22:35:04 < Tectu> did you wife enjoy it as much as you did?
2014-01-22T22:35:50 < gxti> racks on racks on racks
2014-01-22T22:37:02 < zyp> Tectu, you think I had a wife when I was living at the student house next to the uni? :p

2014-01-22T22:44:32 < Tectu> :P

2014-01-22T22:48:15 < Tectu> if you'd be my husband, you'd definitely have gotten some cake.
2014-01-22T22:49:59 < zyp> I tend to eat sweets when I want sweets, so I don't really need a dedicated day for that :)

2014-01-23T01:21:59 < Thorn> anybody tried the latest diptrace beta yet?
2014-01-23T01:22:08 < englishman> sure, a bit
2014-01-23T01:22:12 < englishman> so has dongs
2014-01-23T01:22:27 < Steffanx> me too.. it's ok.
2014-01-23T01:22:32 < Thorn> is it stable?
2014-01-23T01:22:37 < Steffanx> in wine
2014-01-23T01:23:03 < Thorn> website says it's available for linux
2014-01-23T01:23:05 < englishman> well the old version crashed on me too, and was super slow sometimes.... wouldnt call it worse
2014-01-23T01:24:58 < Thorn> I don't remember any crashes
2014-01-23T01:29:11 < gxti> i'm surprised, these china trash LCDs are ENIG, look quite clean, and were made less than 3 months ago
2014-01-23T01:33:28 < dongie> cool
2014-01-23T01:33:34 < dongie> is that from buy-china-lcd or awhatever?
2014-01-23T01:33:45 < gxti> no these are just cheap 16x2 character thingies
2014-01-23T01:33:50 < gxti> from aliexpress
2014-01-23T01:33:52 < dongie> ah
2014-01-23T01:34:20 < Thorn> I wanted to order from buy-display.com but waited too long and it's now chinese new year
2014-01-23T01:34:28 < dongie> heh
2014-01-23T01:34:36 < dongie> i think we bought like 500 16x2 shits from there
2014-01-23T01:34:42 < dongie> they were something like 2-3$/ea
2014-01-23T01:35:00 < Thorn> yes something like that. they also have at least 5 sizes
2014-01-23T01:35:10 < Thorn> I was also looking at 800x480 though
2014-01-23T01:35:12 < dongie> worked good

2014-01-23T01:46:12 < Thorn> have to wait at least 2 weeks

2014-01-23T01:47:33 < qyx_> btw they are improving in quality
2014-01-23T01:47:42 < qyx_> now they are better than our local pcb house
2014-01-23T01:47:58 < qyx_> and about 5 times cheaper

2014-01-23T01:55:30 < gxti> not that any of these character lcds are substantially unique anyway
2014-01-23T01:55:53 < gxti> probably 5 companies making them from stolen gerbers
2014-01-23T01:56:27 < Thorn> those use flat cables with 0.5mm pitch and 3.3v logic (afair)
2014-01-23T01:56:41 < qyx_> hm, 0.5?

2014-01-23T02:02:26 < qyx_> hm, my oleds were 0.7 or something like that

2014-01-23T06:28:35 < GargantuaSauce> yeah as long as it's in an airtight container it should be fine
2014-01-23T06:28:37 < dongie> the propaste i get from japan is double sealed

2014-01-23T06:29:09 < dongie> and when you tighten the cap, it presses the inner plastic cap so its probably nice and airtight

2014-01-23T06:33:50 < GargantuaSauce> you can get a phase-change fridge for like 75 and it'll be more energy efficient than peltiers

2014-01-23T06:41:48 < GargantuaSauce> well. it could double as a one-use reflow oven i guess
2014-01-23T06:42:28 < GargantuaSauce> might be a better idea just to go to walmart and get a beer fridge
2014-01-23T06:44:12 < GargantuaSauce> so fill it with beer

2014-01-23T09:42:29 < dongie> no really tho
2014-01-23T09:42:34 < dongie> why is that trace gfoing across the drill cuts
2014-01-23T09:43:22 < GargantuaSauce> in-panel testing?
2014-01-23T09:43:27 < dongie> ah maybe its gnd pour
2014-01-23T09:43:42 < dongie> it didnt go to any via
2014-01-23T09:43:43 < dongie> it went between 2
2014-01-23T09:44:39 < dongie> amazing TP1 on teh bigger board
2014-01-23T09:44:42 < dongie> covered with mask
2014-01-23T09:45:35 < dongie> zyp is that the same stuff you have?
2014-01-23T09:45:38 < dongie> or did i get wrong shit
2014-01-23T09:45:41 < dongie> i thoguth this nrf thing was bga
2014-01-23T09:47:54 < zyp> ah, that looks like the same thing, yes
2014-01-23T09:48:14 < zyp> I didn't recognize the board at first, I've mostly used the other board in the kit
2014-01-23T09:48:32 < zyp> the pca10001
2014-01-23T09:48:47 < dongie> right
2014-01-23T09:48:58 < zyp> and no, the nrf thing is QFN
2014-01-23T09:49:02 < dongie> hmm
2014-01-23T09:49:04 < dongie> there was some bga one
2014-01-23T09:49:11 < dongie> the one i trolled those indian ring thing with
2014-01-23T09:49:57 < zyp> it seems to me like most RF chips are QFN
2014-01-23T09:50:46 < dongie> http://www.nordicsemi.com/eng/Products/Bluetooth-R-low-energy/nRF51822
2014-01-23T09:51:01 < dongie> nRF51822 is available in 6x6mm 48-pin QFN packages and 3.5x3.8mm 64 ball wafer-level chip-scale packages (WLCSP).
2014-01-23T09:51:04 < dongie> oh
2014-01-23T09:51:09 < dongie> yeah there's a bga variant but probably not for hobby use
2014-01-23T09:51:11 < ds2> they have a BGA
2014-01-23T09:51:17 < dongie> for ds2 use
2014-01-23T09:51:19 < dongie> is ok.
2014-01-23T09:51:23 < ds2> :)
2014-01-23T09:51:40 < dongie> hes the guy who put lunix on F1
2014-01-23T09:51:49 < ds2> that indian ring thing would be more plausible if they explained how they plan to power it
2014-01-23T09:51:51 < ds2> of course
2014-01-23T09:52:08 < dongie> taht indian ring is more plausible if they made it a wrist badn
2014-01-23T09:52:09 < dongie> band
2014-01-23T09:52:26 < dongie> right now it uses tech from 2020 for display and 2030 for batteries and charging
2014-01-23T09:52:58 < dongie> so compare 1:1 TI and NRF kit, nrf seems to be way better value
2014-01-23T09:53:04 < dongie> yo uget 5 free chips to prototype with
2014-01-23T09:53:08 < dongie> 2 jlink debuggers
2014-01-23T09:53:38 < dongie> TI, just evalboards + USB debugger, which means you cant debug 2 at once
2014-01-23T09:53:44 < ds2> the  TI is a 8051
2014-01-23T09:53:47 < dongie> well yes
2014-01-23T09:53:48 < ds2> the nRF is a M0 at least
2014-01-23T09:53:50 < dongie> thats the biggest problem.
2014-01-23T09:54:09 < ds2> but the jlink on the nRF is somewhat special
2014-01-23T09:54:15 < dongie> ? how so
2014-01-23T09:54:18 < dongie> it should be standard jlink
2014-01-23T09:54:20 < dongie> lests see
2014-01-23T09:54:28 < zyp> standard jlink-ob
2014-01-23T09:54:40 < zyp> based on a sam3
2014-01-23T09:54:45 < ds2> no
2014-01-23T09:54:54 < ds2> the SWD on the nRF uses the reset pin
2014-01-23T09:55:03 < ds2> unlike the SWD on the STM32
2014-01-23T09:55:14 < ds2> so that jlink has to be setup a little different
2014-01-23T09:55:27 < zyp> huh?
2014-01-23T09:55:34 < dongie> duno not a problem for me in keil
2014-01-23T09:55:45 < ds2> let me pull up a schematic
2014-01-23T09:55:50 < dongie> J-Link OB-SAM3U128
2014-01-23T09:55:52 < dongie> thats the dongle jlink
2014-01-23T09:55:55 < dongie> tiny one
2014-01-23T09:56:07 < dongie> hmm
2014-01-23T09:56:11 < dongie> im not getting a core readout.
2014-01-23T09:56:12 < dongie> is it swd?
2014-01-23T09:56:18 < dongie> i guess it should be
2014-01-23T09:56:23 < dongie> m0 doesnt do jtag?
2014-01-23T09:56:41 < zyp> there is no jtagap in this chip at least
2014-01-23T09:57:13 < dongie> hmm
2014-01-23T09:57:28 < dongie> not gettin idcode
2014-01-23T09:57:31 < ds2> swdio is shared with nreset
2014-01-23T09:57:55 < ds2> so there is some funky handling needed for it
2014-01-23T09:59:49 < dongie> hmm aids

2014-01-23T11:17:56 < zyp> dongie, I see my pca10000 board also have those traces going towards the breakaway parts
2014-01-23T11:18:08 < zyp> I guess it's the programming interface for the jlink-ob
2014-01-23T11:18:17 < zyp> so they program it, and then break it off

2014-01-23T11:19:58 < dongie> zyp, the crap trace on mine was a ground pour

2014-01-23T11:20:21 < dongie> i dont think those were traces, but its hard to tell because the nasty blocky silk covered teh area wehre it goes into vias
2014-01-23T11:20:59 < zyp> they are, it's pretty obvious when looking at my board
2014-01-23T11:21:24 < zyp> there are two traces going down and ending along the breakaway edge
2014-01-23T11:21:28 < zyp> going to a via each
2014-01-23T11:21:47 < zyp> and it looks like one of yours got ripped off

2014-01-23T12:25:09 < Thorn> why old style debug connector
2014-01-23T12:25:30 < karlp> only for eval, but mounting holes and nice connectors
2014-01-23T12:25:32 < dongie> its not like size is an issue
2014-01-23T12:25:37 < karlp> ready to be boxed up into a product!
2014-01-23T12:25:49 < dongie> haha
2014-01-23T12:35:07 < zyp> karlp, you might want to mount it to something to keep it in place before putting 45V/3A through it
2014-01-23T12:35:23 < zyp> is that a f105?
2014-01-23T12:35:33 < zyp> if so, why 105?

2014-01-23T12:40:18 < vadmeste> Hello everbody. Did someone test RTC Timestamp feature with STM32F429i disco ? Is it possible to consider that my STM32 doesn't support it ?
2014-01-23T12:40:42 < dongie> my testing of 429i-disco involved turning it on
2014-01-23T12:41:18 < vadmeste> dongie: thanks for responding.. so it worked for you?
2014-01-23T12:41:21 < dongie> (further than what some people in here have gotten)

2014-01-23T12:51:59 < vadmeste> dongie: okay, I see. I read the TimeStamp documentation in stm32f4xx_rtc.c and there is one thing that I did not understand which is 'Configure the RTC_AF1 trigger'.. Even Google didn't help me, so could you tell me what does that mean? or points me to some links which explain that ?
2014-01-23T12:52:13 < dongie> sounds like some AFIO stuff?
2014-01-23T12:52:16 < dongie> no?
2014-01-23T12:52:37 < dongie> 2 - PC13 can be used as a GPIO or as the RTC_AF1 pin

2014-01-23T12:57:11 < dongie> it has several samples in RTC section that deal with that pin.
2014-01-23T12:57:21 < dongie> looks like its generic RTC interrupt that can be tied to different shit

2014-01-23T15:01:20 < Claude> wtf@ this matchbox arm thing.. from the description "How all started
2014-01-23T15:01:20 < Claude> About 2 years ago, the ARM revolution started when ARM micro entered in the world of hobby development boards with faster and faster microcontrollers. " . seems like we are now in 2002 ?
2014-01-23T15:01:52 < dongie> the whole thing is a fucking joke
2014-01-23T15:01:57 < dongie> F1-discovery is cheper
2014-01-23T15:01:57 < Claude> indeed
2014-01-23T15:02:01 < dongie> and more available
2014-01-23T15:02:05 < dongie> and more useful than this shit
2014-01-23T15:02:14 < dongie> thier only selling poiint was MSD bootloader
2014-01-23T15:02:15 < Claude> ack ack and ack
2014-01-23T15:02:20 < dongie> which they just ripped from mbed
2014-01-23T15:03:12 < dongie> and they still havent opensoresed any of the shit etc.
2014-01-23T15:03:16 < dongie> entire project is suposed to be open
2014-01-23T15:03:48 < Steffanx> F1 cheaper.. and 100 times larger
2014-01-23T15:03:55 < Steffanx> i mean, the pcb is 100 times larger
2014-01-23T15:03:57 < dongie> and?
2014-01-23T15:04:04 < dongie> does it fucking matter?
2014-01-23T15:04:09 < Steffanx> So it totally depends on what you want to use it for.
2014-01-23T15:04:17 < dongie> for prototyping its irrelevant
2014-01-23T15:04:24 < dongie> for anything that needs to be smaller you're making a pcb anyway
2014-01-23T15:04:29 < Steffanx> nah, you know those people dont use it for prototyping only :P
2014-01-23T15:04:29 < dongie> and not using some limited breakout board.
2014-01-23T15:05:06 < Claude> breadboard? oh learning to solder smd by yourself isn't that hard.

2014-01-23T15:56:27 < dongie> oh thats cute.
2014-01-23T15:56:31 < dongie> put font inside a pattern
2014-01-23T15:56:37 < dongie> hoping to trick it into rotating 45
2014-01-23T15:56:48 < dongie> it rotates assembly layer 45", font stays flat

2014-01-23T16:09:26 < zyp> hmm?
2014-01-23T16:09:42 < dongie> i made a fucking rectangle with dimensions i want and im telling the trash to turn it into a board shape

2014-01-23T17:34:46 < Claude> in pcb is that
2014-01-23T17:35:09 < dongie> yeah
2014-01-23T17:35:11 < dongie> i did that
2014-01-23T17:35:13 < dongie> it doesnt affect the outputs tho
2014-01-23T17:35:26 < dongie> either something new in 14 or im fucking something else up

2014-01-23T19:22:00 < gxti> $500 "suggested" price for that clock, and won't be available for 9 months. from the press release it sounds like pure design wank so i'm impressed they're trying to make it at all.
2014-01-23T19:22:14 < jpa-> eink mobius doesn't look bad.. i wonder what the bare display panel costs
2014-01-23T19:22:16 < dongie> yeah looks utterly worthless
2014-01-23T19:22:25 < gxti> at least it's not on kickstarter

2014-01-24T03:34:58 < gxti> can barely get 4bit mode to work and 30% of the time it glitches on startup. readback to check if it's busy or ready for the next character seems broken. and it can't seem to handle data any faster than every 50us anyway, which is plenty of time to clock it out serially.
2014-01-24T03:35:43 < emeb> old Hitachi LCD interface is an abomination in this modern age.
2014-01-24T03:36:14 < emeb> stupid things should be shitcanned in favor of SPI or I2C drive.
2014-01-24T03:36:30 < gxti> yeah, but this isn't even meeting the shitty spec. must be fake.
2014-01-24T03:36:50 < gxti> it does however seem to work with 3.3v logic which is good. but if i'm using a shift register might as well get one with 5v out.
2014-01-24T03:37:18 < emeb> I've got some code that works fairly well on 4-bit mode. Never had any big issues with it, but the silly startup timing is a PITA.

2014-01-24T04:35:08 < gxti> is there a logic family that can run on 3.3v, and can also run on 5.0v with a 3.3v input? hct/ahct does the latter but not the former, would be nice to have a part i could use for purely 3.3v stuff too
2014-01-24T04:35:41 < amstan> what do you mean 3.3V input?
2014-01-24T04:36:06 < gxti> meaning vdd=5v but logic inputs are 3.3v
2014-01-24T04:37:31 < amstan> you can do that on a lot of chips already
2014-01-24T04:37:47 < amstan> just look what the logic high min voltage is, as long as it's below 3.3V you're probably fine
2014-01-24T04:37:57 < gxti> HCT does that, yes
2014-01-24T04:38:20 < gxti> but it requires vdd > 4.5v. would be nice if there were one part that ran at lower voltages as well.
2014-01-24T04:39:01 < amstan> hmm
2014-01-24T04:39:03 < amstan> fpga? lol
2014-01-24T04:41:15 < upgrdman> anyone know of a bluetooth module that can do HID?

2014-01-24T04:41:35 < amstan> upgrdman: i heard the some modules from bluegiga can do hid

2014-01-24T11:29:57 < dongie> Are you sure the USB is mini USB ? mini USB is already deprecated. Micro USB is more durable, and I believe it is the recommended connector in the EU for all new mobile devices.
2014-01-24T11:30:01 < dongie> who is this retarded jap
2014-01-24T11:30:22 < dongie> did eu go insane and ban mini usb?
2014-01-24T11:30:55 < dongie> i wonder who teh fuck started "more durable" troll on microusb
2014-01-24T11:31:02 < dongie> as soon as you jam the plug backwards
2014-01-24T11:31:06 < dongie> it breaks that fucking 0.5mm thin lip
2014-01-24T11:31:08 < dongie> and youre fucked
2014-01-24T11:33:10 < zyp> it's not designed to be idiot proof, it's designed to move the wear from the socket to the plug so when it wears out you can just throw away the cable instead of your phone
2014-01-24T11:33:44 < dongie> i heard all that.
2014-01-24T11:33:50 < dongie> what doyou say about jamming the shit in reverse.
2014-01-24T11:33:54 < dongie> lip gone -> phone is trash.
2014-01-24T11:34:06 < zyp> mini-B is not deprecated, but mini-A/AB is, so for OTG stuff you're supposed to use micro
2014-01-24T11:34:36 < zyp> dunno, do you even get it in reversed? wouldn't the corners stop you?
2014-01-24T11:35:02 < dongie> duno ask my kids how they figured it out
2014-01-24T11:35:25 < dongie> fact is, its impossible to destroy mini-b plug
2014-01-24T11:35:42 < dongie> one of the displayport adapters i shipped last month fell out of delivery truck and got run over
2014-01-24T11:35:50 < dongie> the chink button got smashed in half
2014-01-24T11:35:56 < dongie> mini-b usb socket just barely scratched
2014-01-24T11:36:23 < zyp> I replaced a mini-b plug on an external hdd for a friend once, because the original had worn out
2014-01-24T11:36:44 < zyp> it was even the pth variant, so it was a bitch to unsolder
2014-01-24T11:37:06 < dongie> because the plug was too loose now?
2014-01-24T11:37:32 < zyp> because the connectors inside the socket was physically worn and almost didn't make connection
2014-01-24T11:37:37 < dongie> hm.

2014-01-24T12:24:22 < FreezingCold> it's freaking massive
2014-01-24T12:24:35 < FreezingCold> it's nearly double the width
2014-01-24T12:24:44 < zyp> sure
2014-01-24T12:24:49 < zyp> and what's the problem with that?
2014-01-24T12:25:10 < FreezingCold> You might as well use Type-B
2014-01-24T12:25:37 < FreezingCold> it's easier to plug in and about the same size really

2014-01-24T12:29:13 < zyp> but there's no shortage of width enough to fit the micro connector

2014-01-24T14:21:01 < Claude> speaking of usb connectors : http://katalog.we-online.de/en/em/614_108_247_221?
2014-01-24T14:22:06 < qyx_> hm, 1500 mating cycles
2014-01-24T14:23:10 < Claude> yeah maybe not the best connector but i like the 'reversible' ideo
2014-01-24T14:23:13 < Claude> idea
2014-01-24T14:23:25 < zyp> sounds silly
2014-01-24T14:23:55 < qyx_> why, how many times did you insert your usb the wrong way
2014-01-24T14:24:12 < qyx_> average person has 50% probability
2014-01-24T14:24:39 < qyx_> you are saving maybe 3 seconds per insert/2 of their lives
2014-01-24T14:25:25 < RaYmAn> Oddly enough, I always find the plug doesn't fit till the third insert attempt ;)
2014-01-24T14:25:35 < Laurenceb> i need some heavy duty data connectors for work projects
2014-01-24T14:25:35 < zyp> proper plugs have a logo on one side, which usually means «up»
2014-01-24T14:25:40 < Laurenceb> any ideas?
2014-01-24T14:25:49 < zyp> getting it right on the first attempt is not a problem
2014-01-24T14:25:58 < Laurenceb> atm im using Hirose ST60-18P
2014-01-24T14:26:05 < Laurenceb> but too fragile
2014-01-24T14:26:23 < zyp> and if you can't take the time to learn that, you deserve to waste time turning the plug over and over
2014-01-24T14:26:30 < qyx_> maybe some circular connectors?
2014-01-24T14:26:45 < RaYmAn> zyp: not all devices have the plug the same way up.
2014-01-24T14:26:52 < RaYmAn> well, socket rather
2014-01-24T14:26:55 < Laurenceb> tbh id prefer rectangular stuff
2014-01-24T14:27:04 < Laurenceb> as it fits in the enclosure better
2014-01-24T14:27:45 < Claude> Laurenceb, centronics type c connectors? aka mini centronics
2014-01-24T14:28:17 < Laurenceb> looks feasible, thanks
2014-01-24T14:31:32 < Laurenceb> or this i guess

2014-01-24T20:30:30 < emeb> lo
2014-01-24T20:31:28  * jpa- steals one data line from emeb's sdram
2014-01-24T20:31:43  * zyp steals the upper byte lane enable
2014-01-24T20:31:46  * emeb spends 2 days trying to debug it.
2014-01-24T20:32:13 < emeb> a humbling experience...
2014-01-24T20:32:32 < jpa-> how did you manage to set it, btw, if it was configured as AFIO?
2014-01-24T20:32:47 < zyp> that's what I also asked
2014-01-24T20:33:07 < zyp> apparently the gpio config came after the sdram config, so it got set back to output
2014-01-24T20:33:36 < emeb> that
2014-01-24T20:33:51 < zyp> and since it was only a lane enable, it was always supposed to be asserted when doing larger than 8 bit accesses
2014-01-24T20:34:15 < jpa-> ah.. yeah, makes sense
2014-01-24T20:37:47 < emeb> the upside is that once I pulled my head out of my ass the SDRAM seems to work just fine.
2014-01-24T20:38:02 < emeb> doesn't even run particularly slow (for this application)

2014-01-25T03:35:50 < ds2> how did you covert it?
2014-01-25T03:36:51 < emeb> Opened it up in MDK5 and looked at what source it needed, then built a Makefile & directory hierarchy with all that stuff in it.
2014-01-25T03:37:07 < ds2> blah
2014-01-25T03:37:14 < ds2> still requires MDK5
2014-01-25T03:37:33 < emeb> I suppose it could be done by trial and error
2014-01-25T03:37:46 < ds2> damn vendors need to stop using those gui shit
2014-01-25T03:37:49 < emeb> or, just include everything and let the compiler sort it out.
2014-01-25T03:38:02 < ds2> that gets messy fast
2014-01-25T03:38:14 < ds2> I was doing that with some f103 code on their site
2014-01-25T03:38:15 < emeb> but MDK5-lite is free download so it's not a huge deal
2014-01-25T03:38:24 < ds2> unless it runs on Linux....

2014-01-25T04:07:31 < emeb> the Touch demo app doesn't need any fancy stuff - it's very basic rectangular geometry stuff.
2014-01-25T04:09:15 < emeb> an no special OS services, just a big loop structure.
2014-01-25T04:14:00 < dongs> oh
2014-01-25T04:14:04 < dongs> it was some mdk sample then?

2014-01-25T04:15:14 < emeb> there's a bunch of stuff in there specifically for the peripherals on the Disco board, including the touch panel sensor, LCD, etc.

2014-01-25T04:15:52 < emeb> just basic lines, boxes, circles, fonts, etc.
2014-01-25T04:16:39 < emeb> and they've got pre-built projects for MDK, Truestudio, IAR, etc.

2014-01-25T04:18:04 < dongs> emwin is like 4meg .lib to link wiht
2014-01-25T04:18:10 < dongs> trhat im sure adds more than 32k by default

2014-01-25T04:37:26 < ds2> speaking of audio...that reminds of an unrelated thing...
2014-01-25T04:38:09 < ds2> emeb: do you know if there is a rule of thumb on selecting base frequencies for PWM output?
2014-01-25T04:39:24 < emeb> ds2: depends on how good your lowpass filter is
2014-01-25T04:39:54 < emeb> and how much ripple you can stand in the final analog output.
2014-01-25T04:40:28 < ds2> emeb: let's say a simple 1 pole, RC filter
2014-01-25T04:40:45 < ds2> the second part is harder for me to asnwer... but let's say telephony quality audio
2014-01-25T04:41:19 < emeb> OK, so 4kHz BW with ~ 48dB SNR.
2014-01-25T04:41:50 < ds2> wow...there is specs on that?
2014-01-25T04:41:52  * ds2 makes notes
2014-01-25T04:42:40 < emeb> telephone quality audio is typically 300Hz - 3500Hz.
2014-01-25T04:43:02 < emeb> a lot of phone stuff runs at 8kHz sample rate with 8-bit companded converters.
2014-01-25T04:43:05 < ds2> all I know is that it is about 12bits linear sampled at 8KHz
2014-01-25T04:43:19 < ds2> that part I know... it is the stuff like SNR
2014-01-25T04:43:37 < ds2> but how does that relate back to ripple allowed?
2014-01-25T04:43:38 < emeb> 12-bit? seems like a lot. But if it's 12-bit then the  SNR is more like 72dB
2014-01-25T04:43:54 < ds2> 8bit companded is about 12bit linear, IIRC
2014-01-25T04:43:59 < ds2> or is it 10bit linear?
2014-01-25T04:44:31 < emeb> well, if you want 12-bit then that's 72dB SNR which means the ripple / noise will be 1/4096 down from the max pk-pk signal.
2014-01-25T04:45:42 < ds2> so max ripple is about 1/2^n?
2014-01-25T04:45:53 < emeb> a 1-pole RC will roll off at 6dB/octave, so for 72dB of ripple rejection you'll need to run the base PWM rate pretty fast.
2014-01-25T04:46:22 < ds2> I am not sure what I want in terms of specs unfortunatley... I just know how a telephone sounds like and I think that is good enough

2014-01-25T04:46:42 < ds2> hmmm
2014-01-25T04:47:30 < ds2> or 20db/decade so that has to be about 4 decades away or 8e7 Hz?
2014-01-25T04:47:57 < ds2> is my interpertation consistant with what you are saying?
2014-01-25T04:48:59 < qyx_> hm, how do i move some const data from .bss to .text?
2014-01-25T04:49:24 < ds2> isn't that a ld script thing to map them that way?
2014-01-25T04:50:22 < emeb> Well, you don't need to go that high since your not interested in signals above 4kHz
2014-01-25T04:50:46 < qyx_> oh wait, nvm
2014-01-25T04:50:51 < ds2> ahhh.. I am using sample rate
2014-01-25T04:50:56 < emeb> right
2014-01-25T04:51:01 < ds2> so 4e7Hz?
2014-01-25T04:51:08 < ds2> (ball park)
2014-01-25T04:51:27 < emeb> basically, the PWM base rate needs to be at least 2x the max bw (nyquist)
2014-01-25T04:51:45 < emeb> so if you want 4k, then the base PWM rate should be at least 8k, but...
2014-01-25T04:51:58 < ds2> ok. that's a lower bound
2014-01-25T04:52:01 < emeb> with a simpler lowpass filter you'll want it to be higher
2014-01-25T04:52:49 < ds2> in case you are wondering... I am trying to see how simple of a setup can I rig up on the BBB to get audio out
2014-01-25T04:52:56 < emeb> right
2014-01-25T04:53:10 < ds2> 1pole is coming from a simple RC filter in front of a common emitter 2N2222 based headphone amp
2014-01-25T04:53:11 < ds2> :)
2014-01-25T04:53:37 < ds2> but those rules basic things are useful to know
2014-01-25T04:53:53 < emeb> so, assume you've got a +3.3V PWM signal @ 8KHz and a 1pole 4kHz RC - that means your 8kHz signal will have an amplitude of 3.3V/2
2014-01-25T04:54:07 < emeb> if it were 16kHz it'd be 3.3V/4, etc.

2014-01-25T04:54:35 < ds2> I see
2014-01-25T04:54:46 < emeb> and if you go > 20kHz then you can't hear the ripple, so it might be academic.
2014-01-25T04:54:50 < ds2> that might explain some stuff that didn't make sense when I played with this in SPICE
2014-01-25T04:55:17 < emeb> If you could run the base rate @ 40kHz then I'd say you're fine.
2014-01-25T04:55:48 < emeb> I know of semi-pro audio synth stuff that works well with PWM base rates of ~ 16kHz, but they use fancier filters.
2014-01-25T04:55:57 < ds2> wow 16KHz
2014-01-25T04:56:01 < emeb> ya
2014-01-25T04:56:03 < ds2> I thought you needed hundreds of KHz
2014-01-25T04:56:12 < emeb> not if you've got a good filter.
2014-01-25T04:56:43 < emeb> so if you cook up a good 4th-order LPF then you can get away with a lower rate.
2014-01-25T04:57:27 < ds2> 'k thanks

2014-01-26T02:01:11 < qyx_> i was only investigating the raw api
2014-01-26T02:02:03 < Laurenceb_> " raw deflate streams to/from files"
2014-01-26T02:02:15 < Laurenceb_> i guess thats quite simple then
2014-01-26T02:02:45 < qyx_> you will have to parse zip headers somehow
2014-01-26T02:03:05 < Laurenceb_> i think it handles that?
2014-01-26T02:03:22 < Laurenceb_> "mz_bool mz_zip_add_mem_to_archive_file_in_place"
2014-01-26T02:03:43 < qyx_> hm, then probably yes

2014-01-26T07:30:11 < englishman> i'll work on it more later, not a lot of time, was just wonder if you had seen that before
2014-01-26T07:31:07 < dongie> thats usually when its failing to comms
2014-01-26T07:31:09 < dongie> for whatever reason
2014-01-26T07:31:58 < dongie> try dropping baudrate down from 115
2014-01-26T07:32:02 < dongie> and make sure parity is even etc
2014-01-26T07:32:47 < englishman> yeah tried the low ones, down to 1200
2014-01-26T07:32:49 < englishman> parity even
2014-01-26T07:33:02 < dongie> and? works over swd?
2014-01-26T07:33:16 < dongie> are you sure youre actually shorting boot while applying power?
2014-01-26T07:33:34 < englishman> no, i don't have any of those connectors, will wire up something when i have time
2014-01-26T07:33:39 < englishman> yeah, same tweezers i use for naze
2014-01-26T07:36:20 < PaulFertser> Unrelated, but last time I tried raspberrypi for talking to the st bootloader, it failed, most likely because of improper support for parity.
2014-01-26T07:42:55 < dongie> no it failed cuz it was raspberry pi!!! lol

2014-01-26T20:43:20 < Steffanx> intercom to phone?
2014-01-26T20:44:26 < Steffanx> Googling "doorbell phone" show some existing ones. Nah, i guess it's "nice" because such a young boy is now an INVENTOR
2014-01-26T20:46:03 < gxti> gotta teach what's important: marketing
2014-01-26T20:56:16 < Robint91> indeed
2014-01-26T20:57:35 < emeb_mac> it's the Rpi school of thought - style is more important than substance
2014-01-26T21:03:30 < englishman> what style
2014-01-26T21:03:34 < englishman> with sd card hanging off etc
2014-01-26T21:03:56 < englishman> no style is needed as long as you have a cute logo and smiling children

2014-01-26T21:31:16 < BrainDamage> take something existing and ok, resell with shitload of hype and pretend it's the next big thing?

2014-01-27T07:52:38 < zippe> Now you know why they are known as Radio Despares
2014-01-27T07:55:31 < zippe> Anyone here know a cheap 68k development board / SBC?
2014-01-27T07:55:47 < zippe> I have a hankering to tinker with something retro...
2014-01-27T07:56:15 < zippe> Cheapest option seems to be to go Coldfire with a Netburner board, but that's kinda overmuscled
2014-01-27T07:58:47 < dongie> buy something from jeri elsworth
2014-01-27T07:58:57 < dongie> shes an inventor

2014-01-27T08:09:15 < dongie> was it called apple classic
2014-01-27T08:10:08 < englishman> no it was called CMM332
2014-01-27T08:10:12 < englishman> found this book

2014-01-27T08:10:50 < englishman> lol, not cheap or available
2014-01-27T08:11:35 < englishman> i think you'll have more fun writing a 68k emulator for stm32
2014-01-27T08:11:51 < dongie> it'll be just as useful, too
2014-01-27T08:12:08 < zippe> Yeah, CMM332 is still available, but asspensive

2014-01-27T08:12:48 < zippe> I have a bunch of Netburner SB70LCs kicking around, they're $60 and tolerable to develop on

2014-01-27T08:14:05 < englishman> ^
2014-01-27T08:14:20 < englishman> ask woz if he has any spare 68k devboards

2014-01-27T12:39:33 < zyp> from where?
2014-01-27T12:40:20 < karlp> digikey
2014-01-27T12:40:45 < zyp> ah, it doesn't show up on digikey.no either
2014-01-27T12:42:09 < karlp> can you get the 429 disco?
2014-01-27T12:44:23 < zyp> not from digikey last time I checked
2014-01-27T12:44:30 < zyp> I got mine from RS, IIRC
2014-01-27T12:44:38 < zyp> and had to fill out some bullshit UK export forms
2014-01-27T12:45:02 < qyx_> wut, why? hw crypto?
2014-01-27T12:47:43 < zyp> hey, looks like I can order one direct from ST
2014-01-27T12:47:57 < zyp> but they want $30 for shipping
2014-01-27T12:48:19 < Thorn> I ordered 429i-disco from farnell and they didn't ask me to file anything. my understanding is distributors eventually apply for some kind of export license for popular products
2014-01-27T12:48:42 < Thorn> there's no hardware crypto in any discovery boards afaik
2014-01-27T12:48:51 < zyp> no
2014-01-27T12:49:00 < zyp> there's a 439 with crypto
2014-01-27T12:49:05 < zyp> (chip)
2014-01-27T12:49:34 < qyx_> hm, i can order f429 from farnell
2014-01-27T12:49:37 < Thorn> is it used in some discovery board?
2014-01-27T12:50:51 < qyx_> at least i can add it to the shopping cart without anything extraordinary
2014-01-27T12:52:28 < zyp> doesn't look like mouser have any problem with selling me the f072
2014-01-27T12:53:47 < karlp> is it fromt he mems parts that I can make nuklear misssiles with or something?

2014-01-27T17:39:48 < gxti> looks pretty useless
2014-01-27T17:40:13 < gxti> it shows you things that random internet trolls have posted
2014-01-27T17:42:50 < BrainDamage> as opposed to man pages, which are what random internet trolls have written in the distro package?
2014-01-27T17:43:50 < gxti> manpages usually aren't written by distro maintainers
2014-01-27T17:44:04 < gxti> they're written by people associated with the actual program and thus have a minor chance of being up to date

2014-01-27T17:45:10 < BrainDamage> eg debian, etc
2014-01-27T17:46:38 < Steffanx> can one format the data(old/new value) a watchpoint outputs in gdb?

2014-01-27T17:56:51 < aadamson> anyone know.... somewhere I thought I read that when using usb and the stms that you shouldn't use an oscillator, and should use a crystal?  I can't find the reference however?

2014-01-27T17:59:58 < jpa-> aadamson: IIRC it is in the reference manual or datasheet somewhere, but USB FS needs +-0.25% clock tolerance per the USB spec
2014-01-27T17:59:59 < zyp> aadamson, it's not stm32-specific
2014-01-27T18:00:07 < zyp> what jpa said
2014-01-27T18:00:21 < jpa-> aadamson: and most STM32's (excluding the newest STM32F0 series parts) have only +-1% internal oscillator
2014-01-27T18:00:56 < jpa-> that said, i have used the internal oscillator just fine for USB, so if it is some hack that you use in room temperature and not a real product, it's probably fine

2014-01-27T18:02:07 < gxti> it also depends what you mean by "shouldn't use an oscillator"
2014-01-27T18:02:36 < Thorn> and with very good Vcc regulation
2014-01-27T18:02:52 < gxti> basically you can't use the internal oscillator, and you can't use the cheaper types of ceramic resonators
2014-01-27T18:03:01 < gxti> but any crystal or canned oscillator will work
2014-01-27T18:03:30 < BrainDamage> <pedant> you're still using the internal oscillator, but adding a better quality filter to it so it's more frequency and temp stable </pedant>

2014-01-27T18:04:25 < gxti> the ones called 'internal', as in HSI and LSI, are not suitable

2014-01-28T10:58:51 < karlp> zyp: oh well, looks like I might have to buy toys on my own krona one day then
2014-01-28T10:59:16 < karlp> got my usb test and measurement class gadget responding properly on the f4 lsat night,
2014-01-28T10:59:48 < karlp> now just need to work out how to handle the transfers bigger than a single 64byte frame properly :)
2014-01-28T11:06:17 < zyp> I guess libopencm3 doesn't include that in the API?
2014-01-28T11:06:27 < zyp> laks currently doesn't, but I've been planning to add it
2014-01-28T11:06:51 < zyp> anyway, the theory is pretty easy
2014-01-28T11:07:03 < karlp> not that I've seen, but there's not a lot of docs on the usb stuff, more demos using it,
2014-01-28T11:07:10 < zyp> every transfer ends with a non-MSP sized packet
2014-01-28T11:07:50 < zyp> so you just send MSP for every frame except the last, and if the total transfer size is divisible by MSP, you terminate it with a zero length packet

2014-01-28T11:08:27 < karlp> yeah, I kinda get that, it's more that it means I need to add a state machine in there probably
2014-01-28T11:08:50 < karlp> I've got to read more of the usbd code to work out what exactly gets done in each call, and where the buffers are.
2014-01-28T11:09:13 < karlp> usbtmc sends an out frame with a message saying, "I'm requesting you to send me in data now"
2014-01-28T11:09:30 < karlp> and you're meant to wait for that before replying, not just writing in data when you feel like it
2014-01-28T11:09:55 < zyp> makes sense
2014-01-28T11:10:17 < karlp> so I have to construct the header once, and then write IN x packets, and then the trailing one, it should all work out, just a bit more work :)
2014-01-28T11:10:41 < karlp> fortunately, I'm prototyping it on the f4 with shitloads of ram/flash
2014-01-28T11:10:45 < zyp> that's easier than handling large OUT transfers :)
2014-01-28T11:10:58 < karlp> well, I have to handle them too, and that doesn't sound so awesome either
2014-01-28T11:11:32 < karlp> it can write to me an custom output waveform for instance, but it's much the same, they send a header in the first frame with the transfer size,
2014-01-28T11:11:40 < karlp> I just need to keep state
2014-01-28T11:11:55 < karlp> then there's a bunch of packets to deal with requesting an abort and acknowledging an abort and so on
2014-01-28T11:12:35 < zyp> sounds similar to mass storage
2014-01-28T11:12:39 < karlp> but I can send a iee488.2 request for identification and it blinks the light and replies with some custom text, that's progress :)
2014-01-28T11:13:11 < karlp> yeah, I should probably look at at some MSC implementations for ideas,
2014-01-28T11:13:17 < karlp> looking at CDCACM probably isn't so relevant
2014-01-28T11:13:42 < zyp> MSC-BBB is based on three transfers per command
2014-01-28T11:14:08 < zyp> one OUT to transfer the SCSI command, one optional IN or OUT to transfer the data, and one IN for status
2014-01-28T11:15:31 < zyp> the first and last are always smaller than MSP, and I believe you only need to terminate the middle one with a ZLP if it's smaller than the size requested in the command
2014-01-28T11:15:46 < zyp> and you're obviously not allowed to send more than the size requested in the command

2014-01-28T11:20:29 < karlp> yeah, the tmc is somewhat odd, you send an OUT with data, which can be 1.."many" packets, then an OUT if you want to request data, then the IN is 1.."many" packets
2014-01-28T11:20:43 < karlp> and they have a distinction between "device dependent" and "vendor specific"
2014-01-28T11:21:01 < karlp> but niether of them are specified at all further than that, so no idea what they meant the difference to be
2014-01-28T11:21:08 < karlp> I guess a subclass was meant to clarify that
2014-01-28T11:24:53 < zyp> heh
2014-01-28T11:28:23 < karlp> I'm probably getting the terminology wrong though, this is the first time I've really done anything with usb in any detail :)

2014-01-28T22:36:10 < wollie88> anyone a clue how to fix this
2014-01-28T22:38:15 < Steffanx> That file is probably part of the l1 standard peripheral lib.
2014-01-28T22:38:52 < Steffanx> And i dont know if you have that or not.
2014-01-28T22:39:52 < wollie88> probably not
2014-01-28T22:39:58 < Steffanx> ( this lib: http://www.st.com/web/en/catalog/tools/PF257913 )
2014-01-28T22:40:32 < wollie88> thanks

2014-01-28T23:32:47 < zeropointo> i'm losing my mind trying to configure openocd with my stm32f103 on ubuntu. i built version 0.7.0 from source. but when i run it with "openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg" it returns "Info : This adapter doesn't support configurable speed"
2014-01-28T23:39:46 < karlp> 0.7 _might_ work, but you'll have vastly more fun with a somewhat recent git build. also more help in #openocd
2014-01-28T23:40:49 < Rickta59> have you ever had it work?

2014-01-29T01:28:31 < GargantuaSauce> yeah not with those, i could probably pull off a really shitty m0 with the rest of my 40xx stuff though

2014-01-29T01:29:33 < qyx_> it's a bit beyond the spec
2014-01-29T01:29:57 < BrainDamage> why arm
2014-01-29T01:30:02 < BrainDamage> subtract and branch if 0
2014-01-29T01:30:12 < GargantuaSauce> i do have an OISC in the works, you know that

2014-01-29T01:35:04 < GargantuaSauce> actually the one i really like is NAND and jump if 0

2014-01-29T13:48:49 < PaulFertser> Retailers lobby now decided to make it hard to receive goods, they want to limit that to <=150EUR a month.
2014-01-29T13:49:12 < karlp> not working with sigrok at the moment, which is a pity
2014-01-29T13:49:25 < PaulFertser> karlp: btw, what's your usecase and what are the impressions so far? (sigrok was my other question)
2014-01-29T13:50:13 < karlp> general lowish speed debug, spi up to maybe 10MHz, serial modbus, timing for rs485 pins,
2014-01-29T13:50:34 < karlp> mostly to have something at home for doing some deeper debug with rather than loitering in the office to use the scope there.
2014-01-29T13:51:33 < Steffanx> You trust this modified sw karlp? :)
2014-01-29T13:51:36 < Robint91_ye_2nd> J-links are normal CDC devices?
2014-01-29T13:51:43 < karlp> so far impressions are that the salaea softwar is ok, functional enough, better than the java OLS client stuff I'd tried, but a little disappointed that it's not working with sigrok,

2014-01-29T16:23:38 < Steffanx> The sw says that with my logic8 clone when i plugin it the "slow" usb port of my pc englishman.. sure it's not an issue with your usb port(s)?
2014-01-29T16:23:55 < englishman> ehh, using the same usbport as i do for logic8
2014-01-29T16:23:59 < englishman> i guess il try another one
2014-01-29T16:24:09 < zyp> it happens if there's not enough bandwidth for the data rate you're running
2014-01-29T16:24:17 < zyp> other devices on the bus will affect it
2014-01-29T16:25:30 < zyp> like, if I have a debugger on the same hub, the burst of traffic from a flash operation can be enough to cause it

2014-01-29T21:21:18 < jpa-> if you do, you must enclose the #include in    extern "C" {}

2014-01-30T00:23:24 < mervaka> is that the thing that uses some proprietary language?

2014-01-30T00:24:13 < mervaka> hmm
2014-01-30T00:24:26 < emeb> It's not the Propeller though - that definitely uses a proprietary language.

2014-01-30T00:25:39 < zyp> mervaka, they have some C extensions
2014-01-30T00:26:12 < BrainDamage> emeb: It's not the Propeller though < so it's potentially more useful than nothing ( enphasis on the potentially )

2014-01-30T00:28:57 < mervaka> yeah, it's a showpiece at Plymouth Uni now :)
2014-01-30T00:29:14 < emeb> IIRC you had DMA issues with that - how did you resolve them?
2014-01-30T00:29:16 < mervaka> they bought it back off me

2014-01-30T00:30:06 < emeb> :)
2014-01-30T00:30:16 < mervaka> but anyway, it was resolved
2014-01-30T00:30:21 < emeb> cool
2014-01-30T00:30:58 < emeb> so what's the innards of the AH mixer based on? (if you can talk)
2014-01-30T00:31:52 < mervaka> there's two LPC4357s in there, plus another ST something

2014-01-30T00:38:22 < mervaka> the whole of R&D is only about 30 strong though
2014-01-30T00:38:43 < emeb> and likely everyone does a little work on a whole lot of products in the pipe...
2014-01-30T00:38:51 < mervaka> 5-8 of us doing firmware
2014-01-30T00:39:08 < mervaka> depending on what firmware you're talking about

2014-01-30T00:39:36 < mervaka> hell yeah, not a bad day so far
2014-01-30T00:40:10 < mervaka> i wanna get myself back into a bit of VHDL further down the line..
2014-01-30T00:40:22 < mervaka> but i dont think i'll be doing that just yet

2014-01-30T00:42:21 < mervaka> but it's a whole load more learning
2014-01-30T00:42:35 < emeb> more channels?
2014-01-30T00:42:35 < mervaka> need to learn how to make PoE powered supplies
2014-01-30T00:42:40 < mervaka> etc
2014-01-30T00:42:54 < emeb> oho - net streamed I/O from the mixer?

2014-01-30T00:43:09 < mervaka> and see if i can get ethernet layer 2 streaming working
2014-01-30T00:43:19 < emeb> nice idea
2014-01-30T00:44:02 < mervaka> make my own packet structure up, with both audio and control data in it
2014-01-30T00:44:52 < emeb> been thinking about an STM32F4 + FPGA audio project. Ethernet would be fun to add.
2014-01-30T00:45:13 < emeb> never done anything with Ethernet tho, so that's a bit unknown
2014-01-30T00:45:26 < mervaka> yeah, apparently it's a bit steep
2014-01-30T00:45:33 < emeb> (as in designing it in myself of course)
2014-01-30T00:45:37 < emeb> gxti uses it a lot
2014-01-30T00:45:44 < mervaka> ive got a discovery board with ethernet breakout board to play with
2014-01-30T00:45:57 < gxti> it's easy
2014-01-30T00:45:58 < mervaka> but first i wanna learn usb
2014-01-30T00:46:31 < qyx_> it works oob most of the time
2014-01-30T00:46:33 < emeb> gxti: you use the STM32 with built-in MAC?
2014-01-30T00:46:34 < qyx_> i like it more than usb
2014-01-30T00:46:49 < mervaka> hmm
2014-01-30T00:46:58 < emeb> or external SPI MAC
2014-01-30T00:47:08 < mervaka> usb or ethernet first? :p
2014-01-30T00:47:16 < gxti> emeb: of course
2014-01-30T00:47:19 < gxti> builtin
2014-01-30T00:47:22 < emeb> kk
2014-01-30T00:47:32 < gxti> using f107 but it's the same MAC as f407
2014-01-30T00:47:33 < qyx_> gxti: you moved to 8081rna?
2014-01-30T00:48:06 < emeb> was someone here saying that the F405 has the MAC in it too, but not documented?
2014-01-30T00:48:16 < bvernoux> emeb: yes
2014-01-30T00:48:22 < emeb> hilarious
2014-01-30T00:48:27 < bvernoux> emeb: it is worng in doc ;)
2014-01-30T00:48:40 < gxti> if it doesn't work you get to keep all the pieces
2014-01-30T00:48:44 < bvernoux> emeb: i saw a board with STM32F405RGT with Ethernet
2014-01-30T00:48:57 < gxti> it's the same as CPUs with cores disabled... they probably work. probably.
2014-01-30T00:49:12 < emeb> wonder if it's just that 405 is a 407 that failed test
2014-01-30T00:49:50 < gxti> except you don't typically buy a crate of 100 CPUs and solder them to a board and require all the cores to work or you lose a lot of money :p

2014-01-30T01:20:20 < dongie> zyp: h,mm. i used with 3V control just fine. my issues were due to wrong phase that would fuck shit up once i fixed that it was ok at any v for cotnrol signal adn 5V for leds
2014-01-30T01:21:16 < englishman> day 2 of waiting for dhl to drive 4.5km to my house and deliver led stripz
2014-01-30T01:21:22 < englishman> been out for delivery since monday
2014-01-30T01:21:52 < dongie> they sound efficient
2014-01-30T01:25:55 < Steffanx> And ofcourse you cannot pick it up yourself englishman..
2014-01-30T01:26:02 < Steffanx> so wonderful.
2014-01-30T01:26:21 < englishman> :-\
2014-01-30T01:26:28 < rigid> englishman: in the meantime, you could checkout http://niftyled.de :-P
2014-01-30T01:29:53 < dongie> heh
2014-01-30T01:30:00 < dongie> too bad its all closed sores
2014-01-30T01:30:33 < rigid> dongie: it's open, free & seeking contributors
2014-01-30T01:30:53 < dongie> i thought hardware wasmt
2014-01-30T01:31:13 < dongie> did this change?
2014-01-30T01:31:32 < rigid> no, i'm still selling stuff. But there's nothing special about it
2014-01-30T01:31:43 < zyp> dongie, yeah, I got it working fine
2014-01-30T01:31:59 < zyp> http://bin.jvnv.net/f/qIUal.JPG
2014-01-30T01:32:25 < englishman> eh its not for hanging behind a tv or anything
2014-01-30T01:32:27 < englishman> cool tho
2014-01-30T01:32:46 < rigid> dongie: niftyled basically does all the stuff, hardware just needs to convert from $PC_INTERFACE to $LED_HARDWARE so greyscale values get to their destination
2014-01-30T01:32:48 < dongie> zyp: nice repurposing of hid controller
2014-01-30T01:33:31 < rigid> englishman: there were plans to merge boblight with niftyled... the author is hanging out in #niftylight ... but, no time :(
2014-01-30T01:33:35 < zyp> just repurposing spare inputs
2014-01-30T01:34:09 < rigid> someone should get niftyled running on some of those fancy smart tv's :)
2014-01-30T01:34:37 < rigid> zyp: nice, what hardware is that?
2014-01-30T01:35:00 < rigid> it's just asking for a niftyled plugin
2014-01-30T01:35:17 < zyp> rigid, it's my HID input board
2014-01-30T01:35:39 < rigid> HID?
2014-01-30T01:35:52  * rigid remembers vaguely the LED HID standard thingy
2014-01-30T01:36:01 < zyp> no, game controllers
2014-01-30T01:36:04 < dongie> caps lock
2014-01-30T01:36:21 < rigid> ah
2014-01-30T01:36:25 < dongie> i think only mactrash can have separate caps on different keyboards
2014-01-30T01:36:31 < rigid> how many LEDs can it control?
2014-01-30T01:37:05 < zyp> those leds are on a serial chain, so there's no limit
2014-01-30T01:37:28 < dongie> well, something like 2k pixels for 2812 i think
2014-01-30T01:37:45 < zyp> it all depends on how often you want to update them
2014-01-30T01:38:03 < zyp> it takes 30us to send the 24 bits for one of those
2014-01-30T01:38:14 < englishman> yeah why would there be a limit
2014-01-30T01:38:24 < ds2> damn PSoC is not hiding enough analog details !@#%$#@#@&*(!@#*(!@(#@
2014-01-30T01:38:34 < englishman> if refresh rate is unimportant its just the current, which you could tap every few miles
2014-01-30T01:38:40 < zyp> datasheet said something about 1k for 30hz
2014-01-30T01:38:53 < rigid> zyp: there's always a limit :)
2014-01-30T01:39:08 < rigid> hm, 30us *calculator*
2014-01-30T01:40:05 < englishman> well, 800kbps, 24 bits/led, 50uS reset time
2014-01-30T01:40:06 < englishman> do maths

2014-01-30T01:42:52 < rigid> zyp: it's good enough for a niftyled plugin... you could combine multiple boards then to do larger installations
2014-01-30T01:43:25 < rigid> you just tell niftyled you want 24 bit data and you get the buffer of greyscale values to push to your hardware in C
2014-01-30T01:43:54 < zyp> what's niftyled?
2014-01-30T01:44:17 < rigid> then use whatever as source. raw netcat, single images, VLC, gstreamer or screen capture is already implemented
2014-01-30T01:44:21 < rigid> zyp: http://niftyled.de
2014-01-30T01:44:22 < zyp> also I'm considering building a dedicated led board which doesn't grab power from USB
2014-01-30T01:44:42 < zyp> ah, ambilight stuff?
2014-01-30T01:44:48 < rigid> yeah... 1k LEDs shouldn't be powered via USB :)
2014-01-30T01:45:03 < rigid> nah, generic LED framework for *nix
2014-01-30T01:45:15 < rigid> well, people told me it's working on windows, but I don't care :-P

2014-01-30T01:48:39 < englishman> update rate rate
2014-01-30T01:49:37 < emeb> heh Hz/s. Since Hz is 1/s I guess that cancels out and it's unitless.
2014-01-30T01:50:03 < zyp> no, 1/s/s is 1/(s^2)
2014-01-30T01:50:13 < emeb> derp - right
2014-01-30T01:50:31 < emeb> maybe it's acceleration.
2014-01-30T01:50:50 < gxti> the number of cycles is multiplied by 400 each second.
2014-01-30T01:50:54 < gxti> impressive.
2014-01-30T01:51:07 < gxti> or added i guess.
2014-01-30T01:51:49 < emeb> just goes faster and faster until it vanishes in a puff of improbability
2014-01-30T01:53:47 < rigid> then you sample every point in the universe at once
2014-01-30T01:54:14 < emeb> maybe that's how the star trek transporter works.
2014-01-30T01:54:41 < rigid> it's certainly how the improbability drive in h2g2 works :)

Has anyone else received any direct email updates to questions or notifications of shipments?

2014-01-30T04:30:55 < GargantuaSauce> they said it'd be in by christmas
2014-01-30T04:31:02 < GargantuaSauce> they just didn't specify WHICH christmas
2014-01-30T04:32:42 < GargantuaSauce> looks like there was a backers-only update today
2014-01-30T04:32:51 < GargantuaSauce> wonder what hilarity that contains
2014-01-30T04:33:10 < GargantuaSauce> oh i guess i could look at the title!
2014-01-30T04:35:21 < GargantuaSauce> i am not raging
2014-01-30T04:35:39 < dongs> the rage is that they fail to deliver

2014-01-30T04:40:59 < dongs> i wish peopel actually bought stm32 breakout boards
2014-01-30T04:41:06 < dongs> then I'd probably sell more than these retards haven't shipped yert

2014-01-30T04:43:47 < emeb> R2COM: I'd say PhD EE guys often have very little practical experience.
2014-01-30T04:44:05 < GargantuaSauce> dongs do you have a more complete dicktrace library of stm32 micros
2014-01-30T04:44:32 < GargantuaSauce> i need f030ct and f103vt and am lazy
2014-01-30T04:45:36 < emeb> R2COM: Depends - I've met some who are very good theoretically, but *only* in their area of specialization.

2014-01-30T05:23:38 < emeb> hmmm... can configure both A and B blocks of the SAI for TX, synchronized.
2014-01-30T05:24:17 < emeb> can also generate data @ the audio sample rate rather than at DMA buffer rate, but this uses ~ 5% of CPU for simple sawtooth.
2014-01-30T05:24:58 < emeb> question is if more complex waveforms can be practically generated @ sample rate...
2014-01-30T05:33:02 < dongs> if its DMA why is it 5%
2014-01-30T05:33:12 < dongs> or 5% for generation

2014-01-30T07:01:05 < upgrdman> well im reading the wiki on superscalar
2014-01-30T07:01:20 < upgrdman> and it seems that many of them have multiple ALUs, FPUs, etc
2014-01-30T07:01:42 < upgrdman> so what makes that different than having multiple cores?

2014-01-30T07:10:15 < upgrdman> ok. that's it?
2014-01-30T07:11:14 < GargantuaSauce> the other main difference is that the control is much more complex
2014-01-30T07:12:14 < GargantuaSauce> instructions will be rearranged and executed simultaneously and the only way to achieve that without changing the resultant computation is fancy dependency checking
2014-01-30T07:13:47 < upgrdman> ok. thanks.

2014-01-30T19:52:43 < twixx> hi, i am having a problem with CAN@STM32F4xx: init works, but i cant write ID, Data etc. to transmit registers, instead it transmits the "preset"-crap of the registers (seen in crossstudio and can-sniffer). i got physical output. any fast fix?
2014-01-30T19:54:15 < Tectu> jpa-, not sure about FREERTOS_OBJS
2014-01-30T19:54:27 < jpa-> Tectu: how so?
2014-01-30T19:57:12 < Tectu> jpa-, not sure - probably I am just too used to the Makefile magic of ChibiOS/RT. You just pick the manual sources you need and compile/link them manually?
2014-01-30T19:57:47 < jpa-> well i did that
2014-01-30T19:58:03 < jpa-> no reason why you couldn't do that when freertos is just like 10 files anyway
2014-01-30T19:58:06 < gxti> chibios isn't that magical
2014-01-30T19:58:37 < gxti> it just hides all the file lists in makefile includes
2014-01-30T19:58:49 < Tectu> I know
2014-01-30T19:58:53 < Tectu> yet makes it nice and easy :P
2014-01-30T19:58:56 < gxti> so do that
2014-01-30T20:00:05 < gxti> mine's more wacky, i like having everything built into build/ but i made it keep the directory structure, which it turns out requires using $(eval) yaaaay

2014-01-30T20:31:41 < gxti> which so far is working nicely. bootloader occupies only the first page, then the last N pages of flash. app starts at page 2 regardless of how big the bootloader is. plus i made a simple table that the bootloader puts in the first page after the ISR vector with info about the hardware like revision and HSE speed.

2014-01-31T10:23:51 < Cyric> moreover, why do i have also initialize the GPIO as AF_PP and so on? is not enought to initialize only the USART_init?

2014-01-31T10:32:07 < dongs> you need to do all of above.
2014-01-31T10:32:18 < dongs> power up gpioa, configure shit as af_pp etc.
2014-01-31T10:32:24 < dongs> is this f1 or f3/f4?
2014-01-31T10:32:36 < Cyric> f1
2014-01-31T10:32:36 < dongs> f1 i think input is IN_FLOATING and output is AF_PP or osmething.
2014-01-31T10:32:39 < dongs> then usart_init.
2014-01-31T10:32:49 < dongs> read teh samples, they show al lteh shit that needs to be done
2014-01-31T10:32:55 < Cyric> yes but i would like to understand why
2014-01-31T10:33:06 < dongs> ? thats how it works
2014-01-31T10:33:23 < Cyric> i mean why usarr do not initialize direcly everthing..
2014-01-31T10:33:27 < Cyric> _)
2014-01-31T10:33:29 < Cyric> :)
2014-01-31T10:33:41 < Cyric> ok
2014-01-31T10:33:51 < dongs> because its not necessarily on GPIOA if you remap etc.
2014-01-31T10:34:35 < Cyric> mmm i havent' studied the remapping yet...
2014-01-31T10:34:43 < Cyric> :S
2014-01-31T10:39:23 < qyx_> there is pin multiplexing, more peripherals could be on the same pin
2014-01-31T10:39:29 < Robint91> question, __throw_bad_function_call is undefined when compiling some C++ code
2014-01-31T10:39:40 < Robint91> what could be the problem
2014-01-31T10:39:48 < qyx_> also the peripheral could be on multiple pins, you have to tell the gpio somehow when to route signals from your peripheral

2014-01-31T12:56:23 < gnomad> calling c++ methods form interrupts is PROBABLY THE WRONG WAY TO DO THINGS.
2014-01-31T12:56:42 < Robint91> gnomad, how else?
2014-01-31T12:57:00 < gnomad> set a flag and handle it outside of the interrupt state
2014-01-31T12:57:17 < gnomad> that is how *all* interrupt handling should be done.
