2015-08-01T09:51:00 < dongs> jpa-: LPC171-something from NXP i guess
2015-08-01T09:51:07 < jpa-> no such chip, it seems to me
2015-08-01T09:51:08 < kakimir_> shiet I have wrong lpc there

2015-08-01T10:00:18 < ReadError> noise shouldnt be too bad since im just feeding off dp832
2015-08-01T10:00:30 < jpa-> that's normal, you'll get 1 bit more accuracy when you use 4x more samples and average them

2015-08-01T10:03:58 < jpa-> i mean, does it match the noise you should get given the datasheet figure and the amount of oversampling you do?
2015-08-01T10:04:24 < jpa-> capacitors across the input do help some
2015-08-01T10:04:43 < jpa-> RC lowpass can also help if there is potential high-freq noise in the signal
2015-08-01T10:05:05 < jpa-> but if it is just the ADC noise, you cannot really remove it except by digital filtering (averaging or median)

2015-08-01T17:58:18 < PeterM> [22:09] <Sync_> no, it controlls the three halfbridges for a 3phase motor controller
2015-08-01T17:58:25 < PeterM> sync more info, curious
2015-08-01T17:59:20 < upgrdman> sounds like a typical hobby esc, no?

2015-08-01T18:10:19 < upgrdman> PeterM, that richtek park looks like  it just 3 pwm inputs... so no way to leave a phase floating?
2015-08-01T18:10:49 < PeterM> i went throug h this before, tristae input for output disable
2015-08-01T18:12:01 < PeterM> Sync_, what is target application, CNC or gimbal or something?
2015-08-01T18:12:34 < Sync_> well

2015-08-01T18:13:28 < PeterM> noice, got phase current monitoring and shit too?

2015-08-01T18:15:25 < Laurenceb__> do you use a driver ic for the angular position?
2015-08-01T18:15:34 < Sync_> I can work with resolvers, quadrature encoders, sin/cos, SSI and endat
2015-08-01T18:16:21 < Sync_> although resolvers are the best :D

2015-08-01T18:17:36 < Sync_> no, the resolver interface is just some analog magic
2015-08-01T18:17:43 < Sync_> suprisingly easy tho
2015-08-01T18:18:01 < Laurenceb__> whats the one with an exciter and sense coils?
2015-08-01T18:18:07 < Sync_> yes
2015-08-01T18:18:11 < Laurenceb__> I thought thats what all the pro stuff uses?
2015-08-01T18:18:20 < Sync_> well, alot of it does
2015-08-01T18:18:29 < Sync_> because you can interpolate the fuck out of it
2015-08-01T18:18:35 < Laurenceb__> yeah
2015-08-01T18:18:47 < Laurenceb__> so whats a resolver?
2015-08-01T18:18:56 < Sync_> that's a resolver
2015-08-01T18:19:01 < Laurenceb__> oh lol
2015-08-01T18:19:01 < Laurenceb__> ok
2015-08-01T18:19:07 < Sync_> I thought you wrote thats instead of whats
2015-08-01T18:19:29 < Sync_> a lot of shiet is now turning to endat/ssi

2015-08-01T18:19:53 < Sync_> (traditionally glass scales)
2015-08-01T18:20:07 < Sync_> because you can just map out the ballscrew error
2015-08-01T18:20:28 < Sync_> and then let the fuckery be done in the servo amp
2015-08-01T18:20:40 < Laurenceb__> ah endat/ssi is protocol
2015-08-01T18:20:42 < Laurenceb__> i see now
2015-08-01T18:20:50 < Sync_> yes, one is basically SPI
2015-08-01T18:20:53 < Laurenceb__> right
2015-08-01T18:21:03 < Sync_> and the other one is a bit more involved
2015-08-01T18:21:07 < Sync_> SSI is spi basically
2015-08-01T18:21:07 < Laurenceb__> is this thing going to be opensource?
2015-08-01T18:21:20 < Sync_> yes
2015-08-01T18:21:37 < Laurenceb__> oh cool
2015-08-01T18:21:53 < Laurenceb__> I was thinking someone should build an opensource servo controller just the other week
2015-08-01T18:22:01 < PeterM> joke about since its german it will be done properly unlike other opensource
2015-08-01T18:22:32 < Laurenceb__> you could talk to my friend Leo

2015-08-01T18:22:57 < Laurenceb__> most of the cost of his system is servo controllers atm, I bet he could build an integrated control unit
2015-08-01T18:23:24 < Sync_> oh is that the thing where a discovery in its packaging lurks in the case?
2015-08-01T18:23:25 < Laurenceb__> and yeah I dont know why this exists

2015-08-01T18:23:55 < Laurenceb__> its very very expensive for a "hobby"

2015-08-02T10:59:49 < PeterM> theres shit like tinder

2015-08-02T11:06:38 < jpa-> so?
2015-08-02T11:07:17 < jpa-> it's not like "maker" excludes "does also professional design"
2015-08-02T11:14:17 < kakimir_> but still does most likely
2015-08-02T11:14:56 < jpa-> how so?
2015-08-02T11:15:17 < kakimir_> fundamental difference in philosophy
2015-08-02T11:15:22 < jpa-> does "maker" in your opinion somehow differ from "electronics hobbyist"?
2015-08-02T11:15:39 < kakimir_> yes
2015-08-02T11:15:47 < jpa-> how?
2015-08-02T11:15:52 < kakimir_> but those are not fundamentally different
2015-08-02T11:16:22 < jpa-> i know quite a few people who do electronics design both as hobby and work
2015-08-02T11:16:49 < kakimir_> yes. all good ones at least
2015-08-02T11:16:59 < jpa-> most of them wouldn't be bothered to buy a half-assed "project board" anywhere, they'd just want the schematic and do it themselves
2015-08-02T11:17:25 < kakimir_> well that's what I mean
2015-08-02T11:17:31 < jpa-> good-quality finished products, sure - but those don't just happen, there is a looong way from prototype to get there

2015-08-02T15:25:17 < Tectu> zyp, jup, you should definitely get one
2015-08-02T15:25:35 < zyp> why?
2015-08-02T15:25:51 < Tectu> zyp, because I think that it is quite a good board and well worth the money

2015-08-02T15:27:59 < Fleck> yes Tectu, it is :D
2015-08-02T15:28:03 < Tectu> there are people working there dedicated to squeeze people into trains?
2015-08-02T15:28:12 < Tectu> Fleck, have you been there?

2015-08-02T18:16:00 < Laurenceb__> ok sir Tectu
2015-08-02T18:16:44 < Laurenceb__> whats the easiest way to take a few ADC readings each second and store to ram?
2015-08-02T18:16:54 < Laurenceb__> with minimal current draw
2015-08-02T18:17:07 < Laurenceb__> I was thinking RTC alarm, but is there a better way?
2015-08-02T18:24:22 < Steffanx> auto wake up .. Laurenceb__
2015-08-02T18:25:10 < Steffanx> oh that thing can be routed to the rtc alarm
2015-08-02T18:25:20 < Laurenceb__> yes
2015-08-02T18:25:45 < Laurenceb__> hmm I wonder what the best stm32 for this is
2015-08-02T18:25:56 < Laurenceb__> I want a button cell powered datalogger
2015-08-02T18:26:12 < Steffanx> L0 i guess
2015-08-02T18:26:13 < Laurenceb__> needs to record a few ADC values per second and do nothing else most of the time
2015-08-02T18:26:58 < Laurenceb__> I'll grab L0 ref manual then :D
2015-08-02T18:36:14 < PeterM> emm ess pee four turdee?
2015-08-02T18:37:14 < Steffanx> he asked for ess tee emm, PeterM

2015-08-02T18:46:32 < mi6x3m> hey STM32, can you advise me on an IDE for the value line discovery?
2015-08-02T18:46:49 < mi6x3m> I know atollic works, but wondering if I can use cocox?
2015-08-02T18:47:52 < Laurenceb__> looks like low power sleep mode on STM32L0 with 256 times hardware ADC oversampling is perfect
2015-08-02T18:48:17 < Laurenceb__>  16 bit samples at 4Hz with 4 years battery life from ~8mm button cell
2015-08-02T18:48:57 < Laurenceb__> using a spirit1 to Tx data every minute or so
2015-08-02T18:50:12 < emeb_mac> what's the application?
2015-08-02T18:52:47 < Laurenceb__> lul
2015-08-02T18:52:56 < Laurenceb__> almost correct
2015-08-02T18:53:01 < Laurenceb__> body temperature measurement

2015-08-02T18:55:07 < emeb_mac> in low power sleep mode there should be very little digital switching noise - probably pretty good samples too.
2015-08-02T18:58:42 < Laurenceb__> well my F1 board already managed 12bit temperature samples
2015-08-02T18:59:00 < Laurenceb__> *manages
2015-08-02T18:59:10 < Laurenceb__> thats with lots of other stuff running
2015-08-02T18:59:30 < Laurenceb__> when the air pumps running full power there is occasional ~3lsb glitches
2015-08-02T19:00:10 < Laurenceb__> annoyingly the noise is too low for oversampling to work properly
2015-08-02T19:00:18 < Laurenceb__> hope they "fixed" this on L0 lol

2015-08-02T23:00:00 < mi6x3m> hey STM32, what does "low density" mean?
2015-08-02T23:00:07 < mi6x3m> (in the context of STM32?)
2015-08-02T23:01:47 < Sync_> they weigh less than the others
2015-08-02T23:02:17 < mi6x3m> :)
2015-08-02T23:02:52 < Sync_> they are intgrated less dense, so less features
2015-08-02T23:03:59 < mi6x3m> Sync_: it's about CoIDE actually. I have the same component for high low and medium density
2015-08-02T23:04:11 < mi6x3m> and wonder what to choose for the value line
2015-08-02T23:06:16 < Sync_> > coide

2015-08-02T23:29:11 < MaDMaLKaV> HI people, quick question. I'm looking to stm32 mcus for a project that needs the mcu to be able to work as an usb 2.0 device and be upgradable by usb. I'm looking at the stm32 web and it is quite crazy becuse it seems mcus inside the same family can have usb support or not, so I have to go seeing one by one.
2015-08-02T23:29:38 < MaDMaLKaV> Also the ST web differentiates between the mcus that can work as "USB device" ans "USB OTG FS" and I don't know the difference
2015-08-02T23:29:43 < MaDMaLKaV> any help will be appreciated :)
2015-08-02T23:29:50 < zyp> OTG means they can also work as host
2015-08-02T23:30:32 < zyp> and yes, there are subfamilies within each family
2015-08-02T23:30:55 < zyp> I think every family have subfamilies that includes usb
2015-08-02T23:31:22 < MaDMaLKaV> the ones that support OTF also support Device ?
2015-08-02T23:31:48 < zyp> yes, OTG in itself refers to the ability to switch between device and host roles
2015-08-02T23:32:23 < zyp> what are the requirements for your project?
2015-08-02T23:32:27 < MaDMaLKaV> good to know. I know what OTG isd as an user but not how it affected from the mcu perspective, if it was inclusive or not
2015-08-02T23:33:11 < MaDMaLKaV> A) must be able to work as an USB device B) must be upgradeable from the same USB port
2015-08-02T23:33:24 < zyp> I would probably suggest going with stm32f407 if you don't have any particular requirements that suggests anything else
2015-08-02T23:33:32 < MaDMaLKaV> nothing else fancy, it is a simple project to start learning arm mcus
2015-08-02T23:33:34 < zyp> since it's powerful and mature
2015-08-02T23:35:04 < MaDMaLKaV> thanks for the help :)
2015-08-02T23:38:44 < MaDMaLKaV> any stm32f4 shall work for my needs, right?
2015-08-02T23:39:25 < zyp> to be honest I don't know the specifics for all the newer f4 subfamilies
2015-08-02T23:39:40 < MaDMaLKaV> seems like all on the web are marked like usb otg
2015-08-02T23:39:44 < MaDMaLKaV> also with f2 family
2015-08-02T23:39:48 < zyp> yeah
2015-08-02T23:39:57 < MaDMaLKaV> the other families are the ones that have usb or not depending of the exact model for what I see
2015-08-02T23:40:00 < zyp> are you designing the hardware yourself?
2015-08-02T23:40:11 < zyp> I'd suggest starting with an stm32f4-discovery board
2015-08-02T23:42:57 < MaDMaLKaV> yeah, looks good and cheap
2015-08-02T23:46:34 < Laurenceb__> http://imgur.com/r/NSFWFunny/OXKQT8g
2015-08-02T23:47:04 < zyp> is that you?
2015-08-02T23:47:23 < Laurenceb__> lol
2015-08-02T23:47:39 < Laurenceb__> does it look like a discovery board

2015-08-03T02:54:37 < dongs> i dont understand pricing on that analyzer
2015-08-03T02:54:44 < dongs> main page says 2gbit buffer ram
2015-08-03T02:54:49 < dongs> sales page says 1mbit
2015-08-03T02:55:06 < dongs> er, 32mbit cuz 1mbit/channel but still shit
2015-08-03T02:55:11 < dongs> and i dont see options for increasing memory
2015-08-03T02:55:37 < dongs> o wait its hte LRxx options
2015-08-03T02:55:47 < dongs> so + 38k for that
2015-08-03T02:55:50 < dongs> hmm, thats kinda cheap
2015-08-03T02:56:09 < dongs> still below price of pokeana with only 72mbit

2015-08-03T08:50:42 < emeb_mac> I've gotten some similar stuff
2015-08-03T08:51:04 < emeb_mac> not exact - mine had circular mount holes & no rounded corners
2015-08-03T08:51:16 < kakimir> http://i01.i.aliimg.com/img/pb/254/944/035/1035944254_392.jpg and found
2015-08-03T08:51:29 < dongs> what "dimensions"
2015-08-03T08:51:36 < dongs> that works
2015-08-03T08:51:41 < jpa-> you probably want a datasheet from the seller also
2015-08-03T08:51:48 < jpa-> because how are you going to use it otherwise?
2015-08-03T08:51:53 < dongs> its 0.96" so it cant be much bigger htan that

2015-08-03T08:56:16 < jpa-> kakimir: doesn't the datasheet tell?
2015-08-03T08:56:32 < jpa-> but pretty easy to estimate from photo & outer dimensions

2015-08-03T08:57:50 < emeb_mac> Yeah - I built a nice bitmap font for a voltmeter with it.

2015-08-03T09:36:13 < dongs> plug it into TIMx_CH1/2 instead

2015-08-03T09:37:25 < dongs> zyp, i thought so too
2015-08-03T09:37:36 < zyp> wonder how usable the software is
2015-08-03T09:37:38 < dongs> the software is absolute shit i think but
2015-08-03T09:37:43 < dongs> its just FX2 that dumps data
2015-08-03T09:37:48 < dongs> and they have some sdk for USB part
2015-08-03T09:37:53 < dongs> to pull raw samples or wahtever
2015-08-03T09:38:11 < zyp> I guess worst case hook it up to sigrok or something
2015-08-03T09:38:58 < dongs> finally something that didnt use fucking sram for buffer
2015-08-03T09:39:03 < dongs> but proper ddr3
2015-08-03T09:39:10 < dongs> so the price is cheap
2015-08-03T09:39:41 < zyp> I like the idea of the replaceable buffer modules too
2015-08-03T09:40:42 < dongs> software comes as sjis-zipped files
2015-08-03T09:40:52 < dongs> so im guessing its complete aids there

2015-08-03T13:28:56 < jpa-> dunno what i should think about that - other registers match the context so it has not randomly jumped there
2015-08-03T13:29:12 < jpa-> perhaps the strange LR is just a result of the IBUSERR?

2015-08-03T14:44:19 < jpa-> dongs: yeah
2015-08-03T14:44:45 < jpa-> in fact it will probably still work as MISO also, just that it will read whatever crap there is on your gpio
2015-08-03T14:45:57 < zyp> even on new style gpio?
2015-08-03T14:46:33 < zyp> how would input pin selection work for functions that can be mapped to multiple pins then?
2015-08-03T14:46:47 < jpa-> hm yeah, probably not on new gpio
2015-08-03T14:47:08 < jpa-> (how does it btw. work if you set the same AF input on multiple pins?)
2015-08-03T14:47:48 < zyp> unsure, I would guess that each pin is gated by active AF and then ORed together
2015-08-03T14:48:02 < jpa-> hm, that would make sense
2015-08-03T14:49:53 < jpa-> that could perhaps also be useful info in some strange situation

2015-08-03T14:56:28 < PeterM> i mean tabs + windows + content of tabs, so i can "close" chrome" and restart/do somethign else, re open chrome and everythign is where it was before
2015-08-03T14:56:41 < dongs> thats easy
2015-08-03T14:56:44 < dongs> just killtask it
2015-08-03T14:56:52 < dongs> it'll annoyingly to ask you to reopen all teh shit
2015-08-03T14:58:35 < PeterM> dongs, that what i do already - i thoguth there might be a cleaner way
2015-08-03T14:59:48 < zyp> uh
2015-08-03T14:59:54 < zyp> doesn't it do that by default for you?
2015-08-03T15:00:10 < zyp> I can quit chrome the normal way, and it'll pop up with everything next time I start it
2015-08-03T15:00:32 < PeterM> how does that work if you ahve mroe than one window?
2015-08-03T15:01:11 < zyp> quit closes all windows at once
2015-08-03T15:02:13 < zyp> dunno how it's on windows, but on os x, there's separate hotkeys for quit (cmd-q) and close window (cmd-w)
2015-08-03T15:02:46 < PeterM> yeah you can ctrl q to quit but what if you only want to re-open one window, or close one window in state
2015-08-03T15:03:40 < jpa-> tabs outliner or something has a way to explicitly save tab groups
2015-08-03T15:03:45 < zyp> idk
2015-08-03T15:03:45 < jpa-> but that is a separate click
2015-08-03T15:03:47 < PeterM> i usually keep seperate windows with tabs for related thigns, ie ,have one window with dk/mouser windows for a project, one window with blogging shit, another for appnotes and shit
2015-08-03T15:04:06 < zyp> only one window is not «entire browser» like you asked for
2015-08-03T15:04:33 < dongs> fuck tabs
2015-08-03T15:04:53 < PeterM> i meant entire browser in the sense that it would cache the loaded webpage, not jsut "bookmark" tyhe url

2015-08-04T05:12:52 < dongs> A piece of software in HTML5 . the technology used to let people read sites on the web . tells websites how much battery is left in a users. phone, and is intended to allow websites to help preserve battery if phones are running low. But that same information can be used to identify phones as they move around the internet, allowing people to be tracked.
2015-08-04T05:12:59 < dongs> realyl, who gives a fuck about your battery level LULZ
2015-08-04T05:13:07 < Roklobsta> mmmm, somehow battery metadata can be accessed by a website to fingerprint a user.
2015-08-04T05:13:51 < Roklobsta> if it can track a user there'd be plenty of interested parties.
2015-08-04T05:14:37 < Roklobsta> dunno how you'd profile a battery.

2015-08-04T05:21:58 < dongs> I would gladly use a MCU with I2C implemented liek taht
2015-08-04T05:22:00 < emeb> he was going to try to do it without writing any code - just wanted to use ST-Link Util to peek/poke.
2015-08-04T05:22:06 < dongs> nice

2015-08-04T05:31:43 < emeb> built a little SDR system over the weekend - 40MSPS 10-bit ADC into an FPGA with tuners, filters, etc.
2015-08-04T05:32:44 < emeb> hooked it to an antenna and looked at what's out there in HF and there's this comb line of 260kHz spaced crap from about 1MHz - 7MHz
2015-08-04T05:33:00 < emeb> can see it on the spectrum analyzer with longwire too.
2015-08-04T05:33:11 < emeb> have no idea where that's coming from.

2015-08-04T06:37:54 < emeb> did an FFT - saw a really strong signal at 7.395MHz.
2015-08-04T06:38:15 < emeb> Almost as strong as local stations - it's NHK - Japan, broadcasting in Swahili.

2015-08-04T13:53:05 < Laurenceb> oh segger
2015-08-04T13:53:17 < Laurenceb> I'd like to see if thats really slower than uGFX
2015-08-04T13:53:54 < Tectu> PointerToNull, uGFX provides features such as dynamically changing fonts, localizations and even keyboard layouts. All during runtim
2015-08-04T13:54:10 < Tectu> just sayin ~
2015-08-04T13:56:18 < PointerToNull> Tectu, that's cool! I didn't know uGFX, seems great! But for the next project.. I already spent a lot of time to customize and create my own library on top of the segger one, and the only missing thing is the internationalization..
2015-08-04T13:56:28 < Laurenceb> hahahah
2015-08-04T13:56:29 < Tectu> PointerToNull, btw, touchkeyboard + physical keyboard stuff is already implemented too. You can change layouts individually
2015-08-04T13:56:37 < Laurenceb> btw, Tectu == uGFX

2015-08-04T14:22:17 < dongs> that looks liek access
2015-08-04T14:22:28 < Tectu> dongs, it is. playing around with it since a few days
2015-08-04T14:23:05 < Tectu> dongs, note that since 2013 you can use access as a GUI to connect to a remote regular SQL database. No more microsoft DB fuckups
2015-08-04T14:23:15 < PeterM> access i nbice to teach you database basics
2015-08-04T14:23:24 < PeterM> and that too tectu
2015-08-04T14:23:42 < dongs> eh,
2015-08-04T14:23:52 < dongs> i used access in ~2000-ish to connect to remote lunixsql shits
2015-08-04T14:23:56 < dongs> via some ODBC/something thing
2015-08-04T14:24:00 < dongs> so it worked since at least that time
2015-08-04T14:24:18 < Tectu> dongs, ah, probably they just changed something. read that as a big feature somewhere (probably some video crap)
2015-08-04T14:24:21 < dongs> maybe they have some native shit now but ODBC has been aroudn fora whie
2015-08-04T14:24:28 < Tectu> jup, that indeed
2015-08-04T14:24:33 < Tectu> I think they did native shit
2015-08-04T14:24:49 < dongs> http://www.tempescope.com/opentempescope/
2015-08-04T14:24:52 < Tectu> anyway. Access seems to be a reasonable tool as long as you use it to do the stuff it was designed for and nothing else
2015-08-04T14:24:52 < dongs> wat =is this hsitngf
2015-08-04T14:25:10 < Tectu> oh, I remember that one, dongs
2015-08-04T14:25:30 < dongs> is that something off hackaday
2015-08-04T14:26:02 < Tectu> no
2015-08-04T14:26:14 < Laurenceb> lol it looks like spoof startup generator
2015-08-04T14:26:55 < PeterM> Laurenceb, it can't be, it isn't a single page that you scroll for fuckign years

2015-08-04T16:05:30 < PointerToNull> I have a doubt about wrapping up c modules/libraries in c++ objects: basically if I have a static or global variable in one of this c modules when I'm going to instantiate multiple objects in c++ of it, the variables are shared, right? So this probably cause some bugs..

2015-08-04T17:07:44 < dongs> i looked at the board againt today
2015-08-04T17:08:06 < dongs> and right before the glue, the traces switch layers and connect to a FI-RE50 footprint

2015-08-04T17:08:48 < dongs> they put glue on stuff so people wouldnt hax it
2015-08-04T17:08:55 < dongs> but the pads for conenctor are right there
2015-08-04T17:09:04 < dongs> and you can solder it on and just make a that ->HDMI converter dongle
2015-08-04T17:09:09 < dongs> and rip 4K with broken hdcp
2015-08-04T17:10:09 < PeterM> or you could jsut do it in software because thats broken too
2015-08-04T17:10:14 < dongs> nah
2015-08-04T17:10:18 < BrainDamage> with the right solvent you can remove epoxy too anyway

2015-08-04T17:10:39 < dongs> BrainDamage: right, but they pured it over vias and shit, probly a bit anoying to fuck with to get to the point where you can solder a tap trace
2015-08-04T17:11:08 < PeterM> since its connector, just make brekaout board that goes into connector

2015-08-04T17:15:37 < dongs> maybe it needs some pin shorted before it enables uart on others

2015-08-05T04:42:57 < dongs> hah nice
2015-08-05T04:43:26 < mtbg> too bad there is no external memory on this board
2015-08-05T04:43:53 < mtbg> it is almost solely limited to computing acceleration
2015-08-05T04:44:27 < dongs> yeah looks like no useful IO on it
2015-08-05T04:44:33 < dongs> did tehy make that for buttcoin mining
2015-08-05T04:44:36 < dongs> just didnt put it on frontpage
2015-08-05T04:44:37 < dongs> lolo
2015-08-05T04:44:49 < mtbg> but there is XC6SLX150 which usually costs >150 eur
2015-08-05T04:46:02 < mtbg> 1.15x
2015-08-05T04:47:26 < mtbg> I got two, 18 eur each, they are perfectly ok, but the PCB darkened on the bottom side under that FPGA
2015-08-05T04:47:35 < mtbg> insufficient cooling, I guess
2015-08-05T04:47:43 < mtbg> yep
2015-08-05T04:48:19 < mtbg> well
2015-08-05T04:48:35 < mtbg> the guy who sold it have had it bought just for bitcoin mining
2015-08-05T04:48:50 < mtbg> and they were no longer usable for that purpose
2015-08-05T04:49:02 < mtbg> since they can get like 100MH/s
2015-08-05T04:49:48 < mtbg> I guess he wasn't even involved in electronics
2015-08-05T04:49:55 < mtbg> just making money on cryptocurrencies
2015-08-05T04:50:41 < mtbg> he still sells them
2015-08-05T04:51:05 < mtbg> lot of 10 pcs of 1.15x for ~200 eur
2015-08-05T04:52:15 < mtbg> the only issue with SLX150 is that it is not supported by free version of ISE
2015-08-05T04:52:41 < dongs> or by vivado
2015-08-05T04:52:53 < dongs> cuz not 7seriers
2015-08-05T04:54:28 < dongs> because its not longer useful for buttcoin
2015-08-05T04:54:47 < mtbg> because of asics
2015-08-05T04:54:53 < emeb> custom ASICs and no more money in it
2015-08-05T04:55:03 < dongs> cuz someone copypasted SHA256 * 1000 into asic
2015-08-05T04:55:07 < mtbg> where a single chip which consumes like 2.5W has 5GH/s
2015-08-05T04:55:08 < emeb> yes

2015-08-05T04:55:38 < dongs> for buttcoin
2015-08-05T04:55:43 < dongs> or still liek 60nm shit

2015-08-05T04:56:12 < emeb> lol no
2015-08-05T04:56:27 < dongs> (two words)
2015-08-05T04:56:40 < dongs> also, just thinking about buttcoin wastes money
2015-08-05T04:56:59 < emeb> used to be you could make money at it, before ASICs & too many cooks
2015-08-05T04:57:06 < emeb> now it's just a waste of electricity
2015-08-05T04:57:11 < mtbg> cryptocurrencies are IMO better idea than fiat money, you could say that it is just mathematics and it represents no value, but what does a banknote represent? the only value is from that someone is willing to exchange that for something you can need
2015-08-05T04:57:23 < mtbg> it is sort of a positive feedback

2015-08-05T05:04:27 < BrainDamage> also people tend instead to buy shares in gigantic computing farms and just get dividends, personal mining hardly profitable in several of those things, unless electricity is free
2015-08-05T05:04:41 < mtbg> the whole mining thing is just a mechanism of distribution, the whole network, regardless of computing power, is supposed to generate fixed units of coin
2015-08-05T05:04:49 < mtbg> in a given time
2015-08-05T05:05:01 < mtbg> fixed number of units*

2015-08-05T05:05:30 < mtbg> yep
2015-08-05T05:05:48 < mtbg> some nice mathematics concepts are evident there

2015-08-05T05:13:39 < mtbg> then you could use anything which have some properties for it

2015-08-05T05:17:10 < BrainDamage> but it seems to irk people off, as if it changes anything
2015-08-05T05:17:42 < BrainDamage> bitcoing was invented to give a buttload of money to early investors
2015-08-05T05:17:51 < BrainDamage> likely the author itself :p
2015-08-05T05:27:53 < mtbg> btw. while playing with that board I found some interesting utility in xilinx ISE which compiles human-readable description of logic functions for specific LUTs and routing fabric configuration into FPGA bitstream
2015-08-05T05:29:23 < mtbg> much lower level than HDLs, like, it can give control of what would be the fpga configured like in the lowest possible level
2015-08-05T05:30:00 < mtbg> one may even disable sanity check in this utility
2015-08-05T05:30:22 < mtbg> and connect conflicting outputs to one signal :>
2015-08-05T05:32:01 < mtbg> it probably would also make it possible to have a open source verilog/vhdl synthesis tool which would generate that human-readable description
2015-08-05T05:32:16 < mtbg> and use it instead of ise
2015-08-05T05:32:41 < mtbg> but, the utility unfortunately has the same licensing mechanism as the whole ISE
2015-08-05T05:33:10 < mtbg> and therefore is limited to the chips that one has a license to make synthesis for

2015-08-05T07:21:56 < aandrew> USART6 (with TX/RX on PC6/7) works fine. USART1 (with TX/RX on PA9/10) has weird glitchy shit on the TXD. USART2 which is on APB1 but has its I/O on PORTA like USART1 works fine as well

2015-08-05T07:51:58 < dongs> yes
2015-08-05T07:52:05 < dongs> use st flash loader

2015-08-05T08:04:05 < upgrdman> seems like most of the lpc17xx registers use, at most, the first 8 bits of most registers. any reason why? are their peripherals just last adaptions from some 8bit trash?

2015-08-05T08:04:22 < jpa-> dunno if you need "stm32f1x unlock 0"  also
2015-08-05T08:04:26 < upgrdman> then even split up the 16bit uart clock divider into two registers

2015-08-05T13:19:49 < dongs> hes bitching about some pad being "removed" while his camera doesnt evne have a resolution needed to show it
2015-08-05T13:20:25 < dongs> hes got 14mil pads with a 12mil trace going accross it at ~150" angle and he's looking for something like 0.015mm of curvature on the open side
2015-08-05T13:21:32 < jpa-> did he invent some reason why it would matter?

2015-08-05T13:27:34 < zyp> the area difference of having the trace into the pad and out again matters much more than that little part
2015-08-05T13:27:46 < zyp> the complaint is silly as fuck

2015-08-05T15:11:31 < Laurenceb> I don't think thats true

2015-08-05T15:11:53 < kakimir> yes
2015-08-05T15:11:53 < Laurenceb> taulabs supports pitot aiui
2015-08-05T15:12:10 < Laurenceb> then you run a coupled control loop thingy
2015-08-05T15:12:32 < Laurenceb> controlling airspeed with pitch
2015-08-05T15:12:47 < Laurenceb> then throttle to go up/down
2015-08-05T15:13:05 < Laurenceb> I spent ages trying to make a decent pitot :-/
2015-08-05T15:13:24 < Laurenceb> I think honeywell "truestability" diff pressure sensors are good enough now
2015-08-05T15:13:40 < Laurenceb> the ardupilot pitot stuff is 5V only and poor performance
2015-08-05T15:13:45 < kakimir> what stops you using aoa sensor as pwm input and then mixing it in
2015-08-05T15:13:53 < Laurenceb> erm...
2015-08-05T15:13:59 < Laurenceb> pwm input??
2015-08-05T15:14:06 < kakimir> or i2c

2015-08-05T15:21:00 < Laurenceb> it works nicely, but only if you turn off the magno
2015-08-05T15:21:26 < zyp> pitot gives dynamic pressure, from which airspeed can be derived

2015-08-05T15:24:02 < aandrew> zyp: yes, but how does that give you AOA?
2015-08-05T15:24:18 < kakimir> it is combination of airspeed and aoa
2015-08-05T15:24:20 < ReadError> kakimir I believe arduplane has code for something like that
2015-08-05T15:24:25 < ReadError> it autotunes over time

2015-08-05T15:27:12 < dongs> aandrew: IFE?
2015-08-05T15:27:13 < Laurenceb> yeah thats another way, dual pitot

2015-08-05T15:34:19 < aandrew> Investigators identified evidence of arcing in wiring of the in-flight entertainment system network, but this did not trip the circuit breakers. The investigation was unable to confirm if this arc was the "lead event" that ignited the flammable covering
2015-08-05T15:34:25 < aandrew> kakimir: had nothing to do with IFE heat
2015-08-05T15:34:36 < aandrew> basically it was an arc fault
2015-08-05T15:34:43 < aandrew> arc != heat, arc == bad connection
2015-08-05T15:34:50 < aandrew> kakimir: lol, afterward
2015-08-05T15:35:01 < kakimir> heat may have been part of issue
2015-08-05T15:35:02 < dongs> The aircraft struck the ocean at 22:31 AT (01:31 UTC) at an estimated speed of 345 mph (555 km/h, 154 m/s, or 299 knots) and with a force on the order of 350g, causing the aircraft to disintegrate in less than a second
2015-08-05T15:35:06 < dongs> that would be cool to watch
2015-08-05T15:35:27 < PeterM> i'd buy tickets... to watch
2015-08-05T15:36:48 < dongs> Both had stopped recording when the aircraft lost electrical power at approximately 10,000 ft (3,000 m), 5 minutes and 37 seconds before impact. nice

2015-08-06T02:18:10 < johntramp> it is to prevent accidental writing of flash, not to protect IP
2015-08-06T02:18:47 < johntramp> I see there is FLASH_OB_Unlock and FLASH_OB_Lock, which I assumed were inverses of each other, but looking closer it seems like they aren't

2015-08-06T11:45:42 < kakimir> anyone recommend chinese precision machining company?
2015-08-06T11:45:47 < kakimir> inexpensives
2015-08-06T11:47:14 < dongs> mfg.com
2015-08-06T11:47:57 < kakimir> sweet dongs
2015-08-06T11:48:52 < kakimir> have you used it?
2015-08-06T11:48:57 < dongs> eah
2015-08-06T11:49:09 < dongs> i mean, they dont make anything, you put up a design and like 20 chinks will quote you
2015-08-06T11:49:14 < dongs> and you pick one that sucks less
2015-08-06T11:49:15 < dongs> and go for it
2015-08-06T11:49:18 < Tectu> is there something in this makefile I might want to improve?  http://paste.ugfx.org/show/323ad00996
2015-08-06T11:49:20 < kakimir> even better
2015-08-06T11:49:27 < kakimir> this is 2015
2015-08-06T11:49:35 < dongs> Tectu: delete it and replace wiht keil project?
2015-08-06T11:51:08 < kakimir> I bet half of local machine shops don't even have proper websites yet
2015-08-06T11:52:28 < kakimir> dongs: they can even assembly stuff for you?
2015-08-06T11:52:33 < dongs> yes
2015-08-06T11:52:44 < dongs> they can do whatever you want as long as youre paying
2015-08-06T11:53:21 < kakimir> better get that money then
2015-08-06T11:54:09 < Sync_> kakimir: look for a local shop, machine time usually costs the same everywhere

2015-08-06T12:04:59 < kakimir> for that price at least that chinaman would do
2015-08-06T12:05:44 < jpa-> depends on shop
2015-08-06T12:06:04 < jpa-> especially laser cutting / water jet cutting you can get quite cheap as the setup cost is low
2015-08-06T12:07:07 < kakimir> cnc turning of small precision parts
2015-08-06T12:08:10 < kakimir> that requires special tools
2015-08-06T12:08:55 < jpa-> lathe stuff is annoying in that CAM is not usually so straightforward as with milling
2015-08-06T12:09:09 < jpa-> will need plenty of drawings and explanation in addition to the 3d model

2015-08-06T13:03:05 < jpa-> oO Sync_ 
2015-08-06T13:03:23 < Sync_> turning usually is easier to draw
2015-08-06T13:03:52 < Sync_> kakimir: you'd be suprised, there are a lot of prototype shops everywhere
2015-08-06T13:03:56 < Sync_> just gotta find the right one
2015-08-06T13:04:01 < jpa-> sure, easier to draw, but you need the drawing
2015-08-06T13:04:14 < jpa-> whereas with milling you can almost just throw a 3d model and say "mill this"
2015-08-06T13:04:27 < Sync_> not really
2015-08-06T13:04:38 < jpa-> and for threading etc. drawing might not even be enough, but extra explanation
2015-08-06T13:04:39 < dongs> this is a laurenceb-class link https://scontent-lhr3-1.xx.fbcdn.net/hphotos-xta1/v/t1.0-9/11813278_10205996123456591_8065041319183391051_n.jpg?oh=77a82eb1c298ec22c9926d9d9446e9d1&oe=565679E3
2015-08-06T13:04:41 < Sync_> if somebody did that to me I'd charge them 300% of the price
2015-08-06T13:04:50 < Sync_> threading will be clear from the drawing

2015-08-06T13:10:40 < Sync_> jpa-: as a shop I expect my customer to deliver a proper drawing with GD&T, otherwise I just turn it down
2015-08-06T13:10:53 < Sync_> because the 3d model is not enough
2015-08-06T13:11:31 < jpa-> it helps, sure
2015-08-06T13:12:03 < jpa-> usually actual manufacturing seems to occur mostly from the 3d model, though - not so with turning

2015-08-06T16:15:41 < jpa-> i guess he means soldering one board to the pcb, connector from that to another board that floats in air and has the nrf51
2015-08-06T16:16:14 < jpa-> you could call it a "shield" for extra points
2015-08-06T16:18:27 < PeterM> yeah, sorta, i mean, you can use something like a mini pcie socket, so you only need a connector on one side

2015-08-06T17:07:28 < PeterM> you didnt miss anything
2015-08-06T17:07:33 < mitrax> he does too but he's not here :)
2015-08-06T17:07:57 < PeterM> it's going to be hard finding a lcd that meeds your needs
2015-08-06T17:08:30 < mitrax> yeah especially since i need low res... 480x272 or 640x480 max
2015-08-06T17:08:59 < mitrax> there are plenty of good TFT with those specs but they're for mobile phone with much higher resolution
2015-08-06T17:09:22 < PeterM> yep
2015-08-06T17:09:44 < PeterM> hmm... 640x480 may still and you in mobile phone territory
2015-08-06T17:11:30 < jpa-> mitrax: nope, no ideas
2015-08-06T17:11:42 < mitrax> jpa-: ok thanks :)
2015-08-06T17:11:45 < jpa-> mitrax: unless eink works for you ;)
2015-08-06T17:12:01 < mitrax> nope :)
2015-08-06T17:12:20 < mitrax> actually it might at some point, but not for this project
2015-08-06T17:13:07 < mitrax> does e-ink still have this annoying inversion (xor like) "artifact" when you refresh?
2015-08-06T17:13:21 < jpa-> yes
2015-08-06T17:15:22 < mitrax> bleh
2015-08-06T17:18:40 < PeterM> mitrax what kinda price are you lookign at?
2015-08-06T17:19:40 < mitrax> price is not really the issue, it's not something that will be mass produced, up to $30-$35 is ok
2015-08-06T17:20:24 < jpa-> that would be pretty cheap for a panel with such qualities
2015-08-06T17:20:35 < PeterM> oh, if thats the case, just use a lower end mobile phone lcd
2015-08-06T17:21:16 < mitrax> hrm, ok well i guess i'm used to price for chinese stuff, what price range do you think that would be?

2015-08-06T17:30:17 < PeterM> i dunno, im sure you can find something, use something like GSMarenas phone finder tool to find a phone with an lcd in the resolution and size you want, check how much replacement lcds cost, if too much, go to next phone, once you've found suitable phone lcd, buy a cheapo phone and a  stack of lcds and get reverse engineering
2015-08-06T17:30:19 < jpa-> well finding a good outdoors tft screen is already pretty difficult
2015-08-06T17:30:30 < jpa-> phone lcd's are probably a good idea
2015-08-06T17:30:39 < jpa-> even though most of them don't work that well outdoors IMO

2015-08-06T23:10:54 < Tectu> zyp, I have a working serial interface and I need a way to pass different messages around (from a desktop computer to an embedded linux device). What I did is creating a message base class that consists of a message type, the payload size and the actual payload (byte array). The message base classs does furthermore contain functions to insert and extract bytes, half words and words into the payload buffer. An actual
2015-08-06T23:10:54 < Tectu> message inerhits from the message base class and provides the high-level API to the user and uses the base classes payload API to actually store and extract the information. Does that sound sane?
2015-08-06T23:11:24 < Tectu> zyp, code:    message.h: http://paste.ugfx.org/show/ae441dce9c      message.cpp: http://paste.ugfx.org/show/2dd676eed0
2015-08-06T23:11:33 < Tectu> zyp, and this is an actual message:  http://paste.ugfx.org/show/bba97075ad
2015-08-06T23:11:46 < Tectu> zyp, note: this is for a private project. no commercialism included
2015-08-06T23:12:04 < Tectu> the display stuff might look suspicious but it is a 7-segment display ;)

2015-08-06T23:12:24 < zyp> that looks like lots of boilerplate and stuff
2015-08-06T23:12:34 < Tectu> zyp, not sure what that means.
2015-08-06T23:12:40 < Tectu> zyp, I am happy to any improvement.
2015-08-06T23:12:44 < zyp> I suggest looking at nanopb
2015-08-06T23:13:16 < Tectu> zyp, the actual messaging works. my actual issue is implementing the receiver side. What do I listen for? do i read n bytes for the message type and the payload size and then allocate more space and read the rest?
2015-08-06T23:13:22 < Tectu> or should I have a message header?
2015-08-06T23:13:29 < zyp> oh, you mean framing?
2015-08-06T23:13:48 < Tectu> not sure?
2015-08-06T23:13:56 < Tectu> nanopb, looks jpa- ish
2015-08-06T23:14:23 < zyp> yes, nanopb is jpa's compact implementation of google's protobuf stuff
2015-08-06T23:14:41 < Tectu> oh, looks like what I need
2015-08-06T23:14:58 < Tectu> wish I new that before. did some googling but not much beside arduino forms. Probably searched for the wrong terms
2015-08-06T23:15:03 < zyp> but I still think that's still just message level, so you still need framing
2015-08-06T23:15:17 < Tectu> zyp, what is framing? The header magic that I might need?
2015-08-06T23:15:35 < zyp> framing is splitting a byte stream into frames, i.e. messages
2015-08-06T23:15:40 < Laurenceb_> wut
2015-08-06T23:15:41 < Laurenceb_> http://ep.com.pl/cache/images/norm/6/6/5/c3JjPS9pbWFnZXMvbm9ybS82LzYvNS85NjY1U1RNMzJMMF84LmpwZyZ3PTQ5NiZoPTI0Nw==_src15f16450428be6c28da1f5938ff61af9.jpg
2015-08-06T23:16:02 < zyp> in general there's two strategies, one is starting each message with a header containing message length
2015-08-06T23:16:03 < Tectu> Laurenceb_, why does it say shield?
2015-08-06T23:16:22 < Laurenceb_> hmm maybe its an add on
2015-08-06T23:16:40 < zyp> and the other is ending each message with a given byte, and escaping that byte all other places it occurs
2015-08-06T23:16:59 < zyp> in general I think I'd prefer the header
2015-08-06T23:17:03 < Tectu> zyp, the second way sounds like a bitch if you want to transfer binary data arrays (sample data) with multi kb size
2015-08-06T23:17:33 < zyp> not really, SLIP and PPP is using that way
2015-08-06T23:17:36 < Tectu> zyp, when you look at my message.h code, do I want to create a separate header class or just transmit the message size before I transmit the actual message?
2015-08-06T23:18:29 < zyp> the latter
2015-08-06T23:18:35 < zyp> framing code should be a separate layer
2015-08-06T23:18:53 < zyp> you pass it a payload of a given size, and when writing it out, the header gets generated and prepended
2015-08-06T23:19:10 < zyp> when reading it, the header gets interpreted directly by the receiving state machine
2015-08-06T23:19:45 < Tectu> protobuf does not necesarily look what I need unless I misunderstand the part that you need to generate and compile a .proto file
2015-08-06T23:20:32 < zyp> protobuf takes the message definition as a .proto-file, and then it generates the language constructs for you to read/write a binary payload
2015-08-06T23:20:32 < Tectu> zyp, so I keep using my current code, send the message size first, then the message and at the receiver state machine I handle stuff correspodingly? How would I handle failures or something? receiver state machine sounds like something that can go wrong quite easily
2015-08-06T23:20:35 < Tectu> timeouts and stuff?
2015-08-06T23:22:20 < zyp> checksumming, explicit start bytes, etc
2015-08-06T23:22:34 < Tectu> meeeh
2015-08-06T23:22:43 < Tectu> now I am not sure if I might want to switch to nanopb right away or finish this first
2015-08-06T23:22:58 < zyp> http://paste.jvnv.net/view/DWpih <- here's some code I wrote once, for handling JVS framing
2015-08-06T23:23:42 < Tectu> zyp, what exactly is framing? putting a header on a message?
2015-08-06T23:23:46 < zyp> JVS is a RS485-based messaging protocol, has a three-byte header and a checksum byte at the end
2015-08-06T23:24:08 < zyp> framing is what lets you pick individual messages out of a bytestream
2015-08-06T23:24:18 < Tectu> I see
2015-08-06T23:24:31 < Tectu> I assume I would include the checksum directly in the message itself in my case?

2015-08-06T23:24:57 < zyp> in JVS, every message starts with 0xe0, so any time the receiver gets 0xe0, it can go back to start receiving a new frame (rxpos = 0)
2015-08-06T23:25:26 < zyp> then it's followed by address (since RS485 is multi-device) and payload length
2015-08-06T23:26:00 < Tectu> do you escape all other 0xe0 or is the state machine just not listening for it as soon as rxpos != 0?
2015-08-06T23:26:12 < zyp> 0xd0 is an escape byte, which is used to escape occurances of 0xe0 and 0xd0 in the actual payload data
2015-08-06T23:26:33 < zyp> yes, all other occurrances are escaped
2015-08-06T23:26:46 < Tectu> I see
2015-08-06T23:26:59 < zyp> see lines 101-106, those handle escaping writes
2015-08-06T23:27:08 < zyp> the header is not escaped
2015-08-06T23:27:15 < Tectu> another consern I am having is type size. char will be pretty much byte everywhere but I use an int for the payload size. this can become a bugger, no?
2015-08-06T23:27:32 < zyp> what?
2015-08-06T23:27:43 < Tectu> will int always be four bytes?

2015-08-06T23:27:47 < zyp> no
2015-08-06T23:27:50 < Tectu> exactly
2015-08-06T23:27:53 < zyp> uint32_t however will
2015-08-06T23:28:10 < Tectu> I see
2015-08-06T23:28:38 < Tectu> zyp, in JVS, the header does not contain the payload size or am I misunderstanding?
2015-08-06T23:28:50 < zyp> third byte of header is payload size
2015-08-06T23:29:07 < Tectu> so then I don´t understand why you would need to escape the payload
2015-08-06T23:29:08 < zyp> payloads are never larger than 255 bytes, so it's only an 8-bit value
2015-08-06T23:29:24 < zyp> so you can handle out of sync situations
2015-08-06T23:29:46 < zyp> if shit happens and you lose track of where you are, you can recover as soon as you see the start of a new message
2015-08-06T23:29:58 < Tectu> why is communication so much pain
2015-08-06T23:30:34 < Tectu> zyp, so do you think that I can keep using my current code for my personal testing until I get fed up with it and switch to something more advanced or is my code shit anyway?
2015-08-06T23:30:44 < zyp> sure you can
2015-08-06T23:30:52 < Tectu> zyp, question about the MessageType in my code. I probably should not use an enum for that but some uint8_t?
2015-08-06T23:31:09 < zyp> C++11 have explicitly typed enums
2015-08-06T23:31:16 < Tectu> good, because I am there
2015-08-06T23:31:28 < Tectu> is that safe to use for my usecase or hacky?
2015-08-06T23:31:35 < zyp> https://en.wikipedia.org/wiki/C%2B%2B11#Strongly_typed_enumerations
2015-08-06T23:32:04 < Tectu> that is pretty neat
2015-08-06T23:32:10 < Tectu> so I can use uint8_t in my actual message
2015-08-06T23:32:19 < Tectu> thanks zyp! :)
2015-08-06T23:33:10 < Tectu> zyp, so I probably want to use uint8_t* for my payload instead as char* too?
2015-08-06T23:33:38 < zyp> yes, use stdint-types for everything where size matters

2015-08-07T01:03:06 < Tectu> just playing around a bit. the next thing I want to do is doing magic in the FPGA which hooks up to the linux framebuffer so I can connect a display through the FPGA and run uGFX

2015-08-07T01:09:50 < yan_> anyone know if the USART on the stm32l151 needs an HSE? or is it just for USB
2015-08-07T01:10:00 < zyp> just USB
2015-08-07T01:10:12 < yan_> and there's no way USB will work without HSE, right?
2015-08-07T01:10:25 < zyp> sure it would
2015-08-07T01:10:35 < yan_> oh just at usb 1.1 speeds?
2015-08-07T01:10:45 < zyp> it's just usb 1.1 speeds anyway
2015-08-07T01:11:12 < zyp> the problem is that it's not stable over the entire temperature range the chip is specified for

2015-08-07T01:11:36 < yan_> oh, but at room temperature it'll Probably WorkTM ?
2015-08-07T01:11:36 < zyp> so it might work, and it might drift out of working range if the ambient temperature rises or sinks
2015-08-07T01:11:55 < zyp> yeah
2015-08-07T01:12:11 < zyp> I wouldn't rely on it for anything serious, but for testing there's no problem in trying
2015-08-07T01:12:14 < zyp> oh
2015-08-07T01:12:33 < zyp> this is assuming that the PLL can make the required 48MHz clock from HSI and whatever
2015-08-07T01:12:40 < zyp> I assume it can, but double check that
2015-08-07T01:13:25 < Laurenceb_> this looks legit

2015-08-07T01:14:01 < aandrew> depends on what you're trying to do
2015-08-07T01:14:24 < yan_> hmm wait a sec, i am using a GPS module that can provide a ~8mhz time pulse.. if i feed it to OSC32_IN, i'm sure i can use that as an external clock source
2015-08-07T01:14:48 < Laurenceb_> dont cross the fields
2015-08-07T01:14:58 < zyp> 8 mhz? in that case you want it to OSC_IN, not OSC32_IN

2015-08-07T04:40:21 < dongs> you can just include stdint.h or hwatever and use uint8_t and such
2015-08-07T04:40:23 < dongs> thats waht I use generally
2015-08-07T04:40:26 < dongs> or unsigned char
2015-08-07T04:40:35 < jadew> yes, it's just a matter of what you're doing
2015-08-07T04:41:05 < jadew> yeah
2015-08-07T04:41:07 < dongs> of course
2015-08-07T04:42:11 < dongs> i prefer types that explicitly define width/signedness so i dont have to guess
2015-08-07T04:42:19 < dongs> oh also n windows tyou can use BYTE
2015-08-07T04:42:23 < dongs> which i think ends up being unsigned char

2015-08-07T04:42:27 < jadew> yeah
2015-08-07T04:43:05 < dongs> if you dont wanna mix those standard/windows types BYTE is probly best choice
2015-08-07T04:43:13 < dongs> as iti s defined in standard windows headers.
2015-08-07T04:43:30 < jadew> meh, char is fine
2015-08-07T04:43:33 < jadew> or unsigned char
2015-08-07T04:43:47 < dongs> char will fuck shit up when it actually needs to be unsigned, no?
2015-08-07T04:43:53 < dongs> memcpy works on BYTE types iwhtout typecase too
2015-08-07T04:43:55 < dongs> typecast
2015-08-07T04:44:08 < jadew> dongs, only if you do math on it
2015-08-07T04:44:32 < dongs> you better hope you're opening it in binary mode too
2015-08-07T04:45:46 < jadew> something else
2015-08-07T04:45:51 < jadew> I use mutexes
2015-08-07T04:46:05 < jadew> because I like my code to be as portable as possible
2015-08-07T04:46:19 < jadew> regardless of the framework I use
2015-08-07T04:46:23 < dongs> jadew: portable to waht?
2015-08-07T04:46:27 < dongs> what portable winapi mutex is there
2015-08-07T04:46:35 < dongs> R2COM: er no
2015-08-07T04:46:42 < jadew> on top of that, the knowledge you get from using standard libraries can be used on other OSes
2015-08-07T04:46:53 < dongs> w h a t
2015-08-07T04:46:55 < jadew> R2COM, there's std::mutex in c++11
2015-08-07T04:47:00 < dongs> o haha
2015-08-07T04:47:08 < jadew> or boost::mutex for previous versions
2015-08-07T04:47:12 < dongs> c++versionthatnobodysupports
2015-08-07T04:47:24 < jadew> dongs, it's supported by most

2015-08-07T04:47:34 < jadew> alternatively you can use boost :)
2015-08-07T04:47:39 < jadew> ah, of course :P
2015-08-07T04:47:39 < dongs> well, keil suports a bunch of c++11 shit now
2015-08-07T04:47:47 < dongs> but their std lib is some ancient stuff
2015-08-07T04:47:54 < dongs> doens't have std::atomic and some otehr crap
2015-08-07T04:48:29 < jadew> R2COM, nothing
2015-08-07T04:48:36 < jadew> but you can do better
2015-08-07T04:48:54 < jadew> there are already utilities for std::mutex
2015-08-07T04:49:19 < jadew> in the way that you don't have to reinvent the wheel
2015-08-07T04:49:32 < jadew> because if you're going to use it without any wrappers, it's gonna get messy
2015-08-07T04:50:12 < aandrew> dongs: yeah, building a new house
2015-08-07T04:50:14 < jadew> I wrote a scope_lock wrapper for critical sections many years ago and posted it online, it got a rating of 2 out of 5 and everyone said it's useless
2015-08-07T04:50:28 < jadew> now there's a thing in the c++ standard called scoped_lock
2015-08-07T04:50:35 < aandrew> won't be the japtech wonderland you have, but in a couple years when I build my workshop I might be able to challenge you :-)
2015-08-07T04:50:55 < jadew> oh, it's actually lock_guard
2015-08-07T04:51:00 < jadew> used to be scoped_lock in boost
2015-08-07T04:51:22 < mtbg> qt has such thing, they call it QMutexLocker
2015-08-07T04:51:37 < jadew> yeah, it's quite common now
2015-08-07T04:52:06 < jadew> R2COM, of course, but the locking mechanism is important too
2015-08-07T04:52:19 < jadew> critical sections offer only the basica functionality
2015-08-07T04:52:22 < jadew> *basic
2015-08-07T04:52:45 < jadew> the libraries that leverage that offer a lot of power compared to what you can do in a short time with just the basic tools
2015-08-07T04:52:55 < jadew> exception handling
2015-08-07T04:52:58 < jadew> recursion
2015-08-07T04:53:58 < jadew> no, like in an exception happens before you can leave the critical section
2015-08-07T04:54:03 < jadew> and you remain with it locked
2015-08-07T04:55:34 < jadew> what do you mean?
2015-08-07T04:55:54 < jadew> the issue is here: EnterCriticalSection(); throw exception(); LeaveCriticalSection();
2015-08-07T04:56:02 < jadew> you never get to LeaveCriticalSection
2015-08-07T04:56:56 < jadew> scoped_lock
2015-08-07T04:57:03 < jadew> or lock_guard how it's called in c++11
2015-08-07T04:57:17 < mtbg> or knowing what you are doing :>
2015-08-07T04:57:17 < jadew> and by using std::mutex
2015-08-07T04:57:26 < jadew> yeah, that can work too :)
2015-08-07T04:57:30 < jadew> R2COM, of course
2015-08-07T04:57:45 < jadew> std::mutex m_mx;
2015-08-07T04:57:49 < mtbg> the lock was probably held for a reason
2015-08-07T04:58:13 < mtbg> so even if it is unlocked automatically as the scope is leaved after the exception is thrown
2015-08-07T04:58:22 < mtbg> you may have messed up your data structures
2015-08-07T04:58:24 < jadew> well, it was held to acess whatever was between the lock and the release and since you're not gonna get to the release, there's no point in holding the lock any longer

2015-08-07T06:02:57 < jadew> can anyone think of a way in which you're told that your code can be improved, that wouldn't hurt your feelings?
2015-08-07T06:03:50 < jadew> yeah, kinda late for that
2015-08-07T06:03:59 < jadew> cuz I did
2015-08-07T06:04:07 < Mr_Sheesh> I've asked why someone picked one way instead of another
2015-08-07T06:05:05 < jadew> and I think I didn't do it as straight as I should have and might have built some tension
2015-08-07T06:06:52 < jadew> well, I don't want things to get shitty between us, but it's my responsability for the codebase to be maintainable
2015-08-07T06:08:13 < jadew> heh
2015-08-07T06:10:09 < jadew> the thing is I told him straight
2015-08-07T06:10:13 < jadew> but nothing changed
2015-08-07T06:10:41 < dongs> jadew: whats the context?
2015-08-07T06:10:51 < dongs> some workproj?
2015-08-07T06:10:54 < jadew> yeah
2015-08-07T06:11:04 < dongs> if someones code is shitty (including mine) i will gladly tell them so
2015-08-07T06:11:15 < jadew> now I'm in the weird possition in which I want the code to be written in a certain way but I already told him and mentioned it several times till it got awkward
2015-08-07T06:11:34 < jadew> culminating to last night when I rewrote what he did and showed it to him
2015-08-07T06:11:56 < jadew> and he said "so I worked for nothing yesterday?"
2015-08-07T06:12:11 < dongs> is your code better? if so, yes he wasted time. who cares.
2015-08-07T06:12:14 < jadew> I kinda stopped there, because I don't want to ruin the good relationship we have between eachother
2015-08-07T06:12:19 < dongs> working good code > shitcode
2015-08-07T06:12:35 < jadew> I didn't merge it
2015-08-07T06:12:50 < jadew> I just showed him the branch
2015-08-07T06:13:09 < jadew> but I wonder how to get him to adopt my way of doing things without being a dick
2015-08-07T06:13:37 < jadew> I can't fire him
2015-08-07T06:13:49 < jadew> yeah
2015-08-07T06:14:01 < jadew> I wouldn't fire him anyway

2015-08-07T06:16:42 < jadew> well, maybe I can get him in that state of mind, because I obviously don't want to push him around
2015-08-07T06:16:53 < jadew> I just want what's best for everyone
2015-08-07T06:21:10 < jadew> it's most likely c++, yeah
2015-08-07T06:21:15 < jadew> but it's not MFC
2015-08-07T06:21:23 < jadew> they wrote that from scratch
2015-08-07T06:21:51 < jadew> it's a new API
2015-08-07T06:22:09 < jadew> WinNT can run multiple subsystems on top of it
2015-08-07T06:22:12 < jadew> one of them is win32
2015-08-07T06:22:22 < jadew> another one is the one ran by the console programs
2015-08-07T06:23:08 < jadew> yeah, they already made WinRT available
2015-08-07T06:23:19 < jadew> it's just like Win32, but more modern I suppose - I never looked into it
2015-08-07T06:23:28 < dongs> err wat
2015-08-07T06:23:32 < dongs> windows apps are native winapi
2015-08-07T06:23:44 < dongs> with some custom stuff for toolbars and shit (tho might be avialbgle somewhere hte ribbon trash)
2015-08-07T06:23:47 < dongs> the rest is just plain winapi
2015-08-07T06:24:10 < jadew> I think he's talking about the new stuff in win10
2015-08-07T06:24:22 < jadew> R2COM, don't think so
2015-08-07T06:24:30 < jadew> well there are two types of programs there
2015-08-07T06:24:30 < dongs> wat new stuff?
2015-08-07T06:24:36 < jadew> dongs, the metro stuff
2015-08-07T06:24:40 < dongs> the 'store' crap is .NET/wahtever
2015-08-07T06:24:44 < dongs> that nobody cares about
2015-08-07T06:24:49 < dongs> or maybe not even .net just javascript
2015-08-07T06:24:50 < dongs> and some crap xml
2015-08-07T06:24:56 < jadew> R2COM, there's the old kind of apps, which are still using win32
2015-08-07T06:25:05 < jadew> and the new stuff which uses WinRT
2015-08-07T06:25:07 < dongs> core appsa re native
2015-08-07T06:25:08 < jadew> which is brand new
2015-08-07T06:25:20 < jadew> they use both

2015-08-07T06:25:34 < dongs> native apps: calc.exe, mspaint.exe etc
2015-08-07T06:25:36 < dongs> are winapi.
2015-08-07T06:25:48 < dongs> shit like stock/weather tickers @ start menu = newshit, i think its javascript or some other crap
2015-08-07T06:25:56 < zapduino> .net
2015-08-07T06:26:02 < jadew> no
2015-08-07T06:26:10 < dongs> pretty sure not .net
2015-08-07T06:26:11 < jadew> they made a new API
2015-08-07T06:26:19 < jadew> which is c++ at its base
2015-08-07T06:26:30 < jadew> and has bindings to .net & other stuff
2015-08-07T06:26:32 < dongs> this is the shit thats "runanywhere" policy i think
2015-08-07T06:26:37 < dongs> so you can recompile for winphone and crap

2015-08-07T06:28:47 < PeterM> >calc doesn't run wit hUAC disabled because calculator is security vulnerability
2015-08-07T06:28:49 < zapduino> most of windows uses this framework
2015-08-07T06:29:20 < jadew> zapduino, that's not an API
2015-08-07T06:29:27 < zapduino> oh
2015-08-07T06:29:38 < jadew> yeah
2015-08-07T06:29:45 < jadew> it's pretty good
2015-08-07T06:30:56 < zapduino> ooh nice
2015-08-07T06:31:13 < jadew> that's because of the COM implementation in C#
2015-08-07T06:31:21 < jadew> well, in .net
2015-08-07T06:31:23 < zapduino> oh
2015-08-07T06:31:33 < jadew> R2COM, well, the serial stuff
2015-08-07T06:31:41 < jadew> R2COM, they probably thought 115200 is max
2015-08-07T06:31:55 < jadew> just like the posix guys
2015-08-07T06:32:24 < zapduino> they follow UART specification... technically it shouldn't go faster than 115,200
2015-08-07T06:32:28 < jadew> no, they probably thought that's how it has to be so they make sure you're not "screwing up" :)
2015-08-07T06:32:42 < zapduino> oh
2015-08-07T06:32:51 < jadew> of course
2015-08-07T06:33:39 < zapduino> this MFC is lower level no?
2015-08-07T06:33:54 < jadew> https://www.cmrr.umn.edu/~strupp/serial.html#3_1_1
2015-08-07T06:34:03 < zapduino> oh
2015-08-07T06:34:07 < jadew> posix :)
2015-08-07T06:34:34 < dongs> you could do overlapped serial wiht.nut too
2015-08-07T06:34:36 < zapduino> oh max looks like 115,200 there too
2015-08-07T06:34:39 < dongs> with pinvoke at least
2015-08-07T06:34:42 < dongs> maybe natively too i duno
2015-08-07T06:36:34 < dongs> how good is latest mfc? last i touched it was like 4.3 or something
2015-08-07T06:36:57 < zapduino> I have this book next to porcelain throne
2015-08-07T06:37:12 < zapduino> not call my attention... maybe I take MFC seriously now
2015-08-07T06:37:13 < jadew> dongs, they bought some controlls from some company in 2008, riddled with bugs
2015-08-07T06:37:18 < jadew> they're still there
2015-08-07T06:37:23 < jadew> (the bugs)
2015-08-07T06:37:38 < dongs> (the controls are gone)
2015-08-07T06:37:46 < dongs> buy stuff, keep bugs, remove code
2015-08-07T06:37:47 < dongs> profit
2015-08-07T06:37:54 < jadew> heh
2015-08-07T06:38:09 < jadew> no, they kept the controls too
2015-08-07T06:38:15 < dongs> arent you using wtl anyway
2015-08-07T06:38:15 < zapduino> Im looking for a specific neural network bot
2015-08-07T06:38:21 < jadew> I am, for most stuff
2015-08-07T06:38:26 < zapduino> it calls itself george... anyone seen it?
2015-08-07T06:38:36 < dongs> me2 like once a year when i actally need to do some winapp stuff
2015-08-07T06:38:58 < jadew> but the reality is that wtl has been left behind
2015-08-07T06:39:26 < jadew> I really don't know why, because they opensourced MFC too, so it's obviously not the opesnource part
2015-08-07T06:40:11 < jadew> R2COM, well, it's about the same with WTL if you have the right setup and on top of that, it's much much cleaner and faster
2015-08-07T06:40:25 < jadew> that's true, but we're not debating that :)
2015-08-07T06:41:26 < jadew> well, that means that a lot less code will run
2015-08-07T06:41:29 < jadew> which means faster
2015-08-07T06:42:01 < jadew> yeah
2015-08-07T06:42:03 < jadew> it's the same shit
2015-08-07T06:42:34 < jadew> yeah
2015-08-07T06:43:02 < jadew> you know what's silly? MS has been sitting on an awesome UI library for a decade
2015-08-07T06:43:07 < jadew> but they didn't release it
2015-08-07T06:43:23 < jadew> the one they used in VS
2015-08-07T06:43:35 < jadew> starting with VS 2005
2015-08-07T06:43:39 < jadew> that stuff was awesome
2015-08-07T06:43:45 < jadew> and it wasn't part of any public framework
2015-08-07T06:44:33 < jadew> and what did they do instead?
2015-08-07T06:44:42 < zapduino> Windows 10 will be the best....
2015-08-07T06:44:43 < jadew> they bought that library that imitated their libray!
2015-08-07T06:44:46 < zapduino> spy tool
2015-08-07T06:44:47 < jadew> and added that to MFC
2015-08-07T06:45:56 < jadew> I bet that if they gave the VS code to a bunch of devs they could have extracted all the controlls out of it, regardless of how they were built and ported them to MFC or WTL or whatever
2015-08-07T06:46:29 < jadew> no, I mean their own devs
2015-08-07T06:46:32 < jadew> they have tons of them
2015-08-07T06:47:12 < jadew> the point being that they're an OS manufacturer and there's no reason why they wouldn't offer good tools to developers
2015-08-07T06:48:14 < jadew> on the other hand they allways pushed the boundaries so maybe that's why they gave up on the old technology and focused on the new .net stuff
2015-08-07T06:48:56 < jadew> they do
2015-08-07T06:49:08 < jadew> they usually write their own UI libraries or they buy thrid party ones
2015-08-07T06:49:33 < jadew> which is sad
2015-08-07T06:52:38 < jadew> that's the thing, they already did

2015-08-07T06:56:11 < jadew> but don't give up on it entirely, it's worth reading a bit about it when you get some free time

2015-08-07T07:28:46 < dongs> that battery will not last
2015-08-07T07:28:47 < dongs> so
2015-08-07T07:28:50 < dongs> it is not practical for me.
2015-08-07T07:29:25 < dongs> That means somewhere between about 170 to 230 miles of real-world range

2015-08-07T07:31:40 < dongs> but i duno i usually just use cruisecontrol
2015-08-07T07:31:55 < dongs> on highway, so evne prius ends up mostly driving electric when it can and then charging up teh battery
2015-08-07T07:33:49 < dongs> hm i ahve an account for gas so i duno how much it costs
2015-08-07T07:33:55 < dongs> but i think its 30L tank

2015-08-07T08:21:09 < dongs> Is there any protection for the LiPo itself? Something that stops the charging process when the LiPo gets close to its minimum voltage level.

2015-08-07T08:21:15 < dongs>  Sampson  10 points
2015-08-07T08:21:17 < dongs> When the LiPo voltage is below the cut-off value. it will cut the output to protect the LiPo.

2015-08-07T12:25:08 < dongs> should I hold on to it for now?

2015-08-07T13:34:57 < jpa-> yeah
2015-08-07T13:35:09 < jpa-> if you don't need portability / extensibility, a simple struct is fine
2015-08-07T13:35:20 < Tectu> well, getters/setters for ease of access for the actual message classes: http://paste.ugfx.org/show/590fcd3e9f

2015-08-07T13:37:08 < Tectu> trepidacious, zyp shoed me nanopb after I wasted a few hours on this already
2015-08-07T13:37:23 < Tectu> zyp, how portable is the __attribute__((packed)) thing?
2015-08-07T13:37:26 < dongs> buttpacked
2015-08-07T13:37:28 < zyp> gcc
2015-08-07T13:37:29 < dongs> very
2015-08-07T13:37:32 < zyp> probably clang as well
2015-08-07T13:37:35 < trepidacious> The general reason for getters/setters is not ease of access, but encapsulating the implementation, so in theory you can have something more complex than just a field access in the getter/setter
2015-08-07T13:37:36 < dongs> msvc/keil/etc
2015-08-07T13:38:03 < Tectu> trepidacious, in this case it is ease of access because everything is inside a uint8_t[]
2015-08-07T13:38:06 < jpa-> i have never used nanopb so can't say for sure, but if you will ever have several versions of firmware connected together, the back/forwards compatibility features of protobuf will be very nice
2015-08-07T13:38:10 < zyp> dongs, msvc supports that? I thought msvc used #pragma pack instead
2015-08-07T13:38:23 < Tectu> jpa-, you have never used your own stuff?
2015-08-07T13:38:25 < dongs> zyp, o rite,
2015-08-07T13:38:32 < dongs> i guess i meant it can pack structs
2015-08-07T13:38:34 < jpa-> Tectu: things happen
2015-08-07T13:38:34 < trepidacious> Tectu: Ah well there you go - that's the same thing really, if the implementation changes you can preserve the getter/setter
2015-08-07T13:39:11 < Tectu> zyp, so after all I can just make each class become a struct, use packed attribute and I am ready w/o any base class and stuff?
2015-08-07T13:39:13 < trepidacious> jpa-: I thought you wrote nanopb?
2015-08-07T13:39:24 < Tectu> trepidacious, at least the front page says so

2015-08-07T14:41:47 < Tectu> well, I got    readByte()
2015-08-07T14:41:53 < Tectu> and writeByte()
2015-08-07T14:41:56 < Tectu> for the serial interface

2015-08-07T14:43:01 < Tectu> jpa-, receive_my_data() would receive sizeof bytes and put it at &mystruct?
2015-08-07T14:43:09 < jpa-> i hope so
2015-08-07T14:43:14 < Tectu> jpa-, but then I need one of those per message struct, no?
2015-08-07T14:43:27 < Tectu> my previous implementation had a base class so polymorphism in your face all the way
2015-08-07T14:43:30 < jpa-> uh, void* to the rescue
2015-08-07T14:43:49 < jpa-> void receive_my_data(void* buf, size_t num_bytes);
2015-08-07T14:44:01 < jpa-> code C like it's 1989
2015-08-07T14:44:41 < Tectu> seems legit

2015-08-07T14:45:06 < Tectu> probably going to make that uint8_t becoming a void
2015-08-07T14:45:42 < jpa-> or you can cast the pointer for extra good undefined behaviours!

2015-08-07T14:54:01 < Tectu> jpa-, I have a noob question about data conversion: I use qextserialport which has   write(const char* data, size_t size);
2015-08-07T14:54:10 < Tectu> what is the correct way to pass my struct to that?
2015-08-07T14:54:21 < Tectu> do I simply c-style cast it?
2015-08-07T14:54:46 < Tectu> or will this fuck things up in some cases?
2015-08-07T14:54:51 < jpa-> i would simply c-style cast it, but what is the "correct way" is a too difficult question :)
2015-08-07T14:55:51 < mitrax> Tectu: if your code is C++ write(reinterpret_cast<char const*>(&struct), sizeof(struct));
2015-08-07T14:55:52 < Tectu> well, I guess static_cast is always correcter
2015-08-07T14:56:05 < Tectu> mitrax, oh, static_cast will not work on this one?
2015-08-07T14:56:09 < mitrax> Tectu: no
2015-08-07T14:56:19 < Tectu> mitrax, isn´t reinterpret_cast just a wrapper around the C-style cast anyway?
2015-08-07T14:56:48 < mitrax> well it's identical to what you would get with a c style cast, but it's not a macro or anything, it's a c++ construct
2015-08-07T14:57:57 < mitrax> it basically means take that pointer and make it a pointer to another type without any modification
2015-08-07T14:59:06 < Tectu> okay. I am using that now, mitrax

2015-08-07T15:10:57 < trepidacious> Tectu: The advantage of protobuf over structs (IMHO) is that it's very portable, and it has forwards/backwards compatibility using optional elements
2015-08-07T15:11:24 < trepidacious> Tectu: Also if size really matters, variable size integers can be smaller in protobuf, it uses an encoding that allows smaller values to use less space (at least when encoded)

2015-08-07T15:45:20 < Tectu> <60x /5xb &msgHeader
2015-08-07T15:45:20 < Tectu> >&"x /5xb &msgHeader\n"
2015-08-07T15:45:20 < Tectu> >~"0x29c4bc:\t0x2a\t0x0c\t0xa2\t0x6b\t0x0c\n"
2015-08-07T15:45:20 < Tectu> >60^done
2015-08-07T15:46:05 < Tectu> the window which directly shows the objects/values tells me that uint8_t msgType = 42 and uint32_t msgSize = 12
2015-08-07T15:46:11 < jpa-> 0x2a 0x0c 0xa2 0x6b 0x0c   doesn't look very packed to me
2015-08-07T15:46:59 < jpa-> what does     p sizeof(msgHeader)    say?
2015-08-07T15:46:59 < Tectu> my structs: http://paste.ugfx.org/show/ad521e86ed
2015-08-07T15:47:04 < Tectu> pretty much packed, no?
2015-08-07T15:47:24 < Tectu> using GCC on both Qt and non-qt side
2015-08-07T15:51:41 < Tectu> jpa-, also sizeof(MsgHeader_t) equals to 5. I assume that this would not be the case when it is not packed?
2015-08-07T15:52:30 < jpa-> more like something is fucked up, as the bytes are silly
2015-08-07T15:53:26 < Tectu> jpa-, this is my Qt code. Can you have a look? http://paste.ugfx.org/show/87990f792b
2015-08-07T15:54:48 < jpa-> nothing worth looking there
2015-08-07T15:55:13 < Tectu> uuh
2015-08-07T15:55:19 < Tectu> any wild ideas/suggestions?
2015-08-07T15:56:27 < jpa-> write data to file?
2015-08-07T15:56:38 < jpa-> so that you'll atleast know on which end the problem is
2015-08-07T15:56:44 < jpa-> then make minimal reproducible code
2015-08-07T15:57:00 < Tectu> does not get much more minimal than what I have
2015-08-07T15:57:12 < Tectu> jpa-, do I do some linux magic to hexdump the file content or something?
2015-08-07T15:57:33 < rewolff> Tectu, in that "read" function of yours you'd want a loop:
2015-08-07T15:58:17 < jpa-> Tectu: but your current code is not possible for us to run
2015-08-07T15:58:36 < rewolff> while bytes_to_read > 0) {
2015-08-07T15:58:36 < rewolff>    br = read (...);
2015-08-07T15:58:36 < rewolff>    bytes_to_read -= br;
2015-08-07T15:58:36 < rewolff> }
2015-08-07T15:59:14 < jpa-> rewolff: hum, fread should read 1 item or 0
2015-08-07T16:00:14 < Tectu> jpa-, well fread should read five bytes when I set size to 5 and count to 1
2015-08-07T16:00:29 < jpa-> i agree
2015-08-07T16:00:45 < rewolff> Hmm. Maybe you're right. But normal "read" would return after say "2" bytes, and then fill the 42, 12 into the struct, and leave garbage in the remaining three bytes....
2015-08-07T16:01:17 < Tectu> jpa-, writing stuff to a file now using QFile::write()
2015-08-07T16:01:19 < Tectu> jpa-, 2a3e ce6b 0c00 0000
2015-08-07T16:01:27 < Tectu> at least that is what sublime text tells me when I open the file in it
2015-08-07T16:01:34 < rewolff> The return value would then be "2" and you'd have to reissue the read.
2015-08-07T16:01:50 < rewolff> wrong byteorder, wrong data, right?
2015-08-07T16:02:07 < Tectu> rewolff, not understanding what you are trying to tell me
2015-08-07T16:02:36 < Tectu> rewolff, after all the data already seems wrong on the sender side according to jpa- debugging skillz
2015-08-07T16:02:51 < jpa-> Tectu: so it writes 8 bytes, even though you claim sizeof(MsgHeader_t) is 5?
2015-08-07T16:02:52 < rewolff> I've jumped into this conversation. MIght have missed something. I'm not sure where your "fread" comes from and how well-tested it is.
2015-08-07T16:03:01 < rewolff> Hmm.
2015-08-07T16:03:46 < Tectu> jpa-, uhm, something happened. now sizeof is 8
2015-08-07T16:04:12 < jpa-> maybe your make clean rule is broken :)

2015-08-07T16:05:10 < Tectu> jpa-, trying that now. but on the ARM side sizeof is 5, on qt side it is 8
2015-08-07T16:05:12 < Tectu> trying clean now
2015-08-07T16:06:53 < Laurenceb_> you are make uGFX compatible with Qt  ?
2015-08-07T16:06:58 < Tectu> Laurenceb_, no ugfx invovled
2015-08-07T16:07:03 < Laurenceb_> oh
2015-08-07T16:07:04 < Tectu> jpa-, sizeof on Qt side is still 8
2015-08-07T16:07:11 < Laurenceb_> Qt on F7 discovery?
2015-08-07T16:07:17 < Tectu> jpa-, but  __attribute__((packed))   is there
2015-08-07T16:07:26 < Laurenceb_> so you could run taulabs gcs :P
2015-08-07T16:07:43 < Tectu> jpa-, ideas?
2015-08-07T16:08:32 < jpa-> make source that i can compile?
2015-08-07T16:09:09 < Tectu> jpa-, will take some time, sec
2015-08-07T16:09:09 < Tectu> jpa-, need a working qt project or just a demo main.cpp?
2015-08-07T16:09:23 < jpa-> whatever demonstrates the problem and i can compile
2015-08-07T16:11:20 < Tectu> jpa-, this gives 8 at my side:  http://paste.ugfx.org/show/1bb12984e8
2015-08-07T16:11:47 < jpa-> how do i compile it?

2015-08-07T16:32:02 < Tectu> jpa-, wtf is this fuck
2015-08-07T16:32:06 < Tectu> jpa-, any workarounds?
2015-08-07T16:32:27 < Tectu> somebody suggested   __attribute__((ms_struct, packed));   but that does not do the trick either
2015-08-07T16:33:11 < jpa-> nah, that was a way to reproduce the problem on linux
2015-08-07T16:33:18 < jpa-> i still say you don't need packed
2015-08-07T16:33:51 < Tectu> will my embedded liux gcc stuff pack the unpacked structs the same as on my windows host crap?
2015-08-07T16:34:06 < jpa-> probably
2015-08-07T16:34:08 < Tectu> i thought packaging is not only to reduce size but to prevent alignment issues
2015-08-07T16:34:19 < jpa-> but i don't think so
2015-08-07T16:35:09 < jpa-> i wonder if    __attribute__((gcc_struct, packed))  might work
2015-08-07T16:35:55 < jpa-> i'd just leave the packed crap out

2015-08-08T01:10:04 < zyp> dongs, digikey shipped shit now, lemme know if you want tracking
2015-08-08T01:11:26 < zyp> they didn't confirm that they actually shipped rev3 though, and I'm not sure I'd want to pay for the rest of the parts before you've confirmed that
2015-08-08T01:12:47 < zyp> for some reason they defaulted to fedex rather than ups, but I guess that doesn't matter
2015-08-08T01:12:57 < karlp> speaking of versions, I was looking at an nxp 1359 or something dev board,
2015-08-08T01:13:14 < karlp> notes from nxp say, "swo doesn't work on reva/b, get revc"
2015-08-08T01:13:29 < zyp> sounds fun
2015-08-08T01:13:50 < zyp> swo doesn't sound that critical though
2015-08-08T01:14:28 < karlp> asked mouser about it, flat out, "we don't support version checking" https://pastee.org/bxa6n
2015-08-08T01:15:10 < karlp> no, not critical, but if I' going to buy one, I'd rather have rev c, given that it's only for diversity testing and oocd/locm3 shitz, not because it's some product I really want to evaluate.
2015-08-08T01:15:21 < zyp> true
2015-08-08T01:15:28 < karlp> oh, note this is only the rev of the dev board
2015-08-08T01:15:38 < zyp> they told me something similar
2015-08-08T01:15:46 < zyp> «Our products team advised that unfortunately we do not track device’s revision.»
2015-08-08T01:15:56 < karlp> yeah, you have a more valid case to make though :)
2015-08-08T01:16:02 < zyp> so I mailed them back and asked them to send somebody over to check what they had on the shelf
2015-08-08T01:16:43 < zyp> eventually they replied with «We have been notified by the supplier that we have not been shipped any devices that are revision 3, unfortunately.»

2015-08-08T01:24:07 < zyp> hehe
2015-08-08T01:24:17 < zyp> in my case, digikey have been more helpful
2015-08-08T01:24:48 < zyp> now, if they just made sure that I'm actually getting rev3 now like they promised, then I'll be happy
2015-08-08T01:24:55 < karlp> I went to digikey first.  first three dev boards I tried adding they rejected outright, closed the tab. fuck em
2015-08-08T01:25:14 < zyp> haha, because of .is?
2015-08-08T01:25:34 < karlp> yeah
2015-08-08T01:25:38 < karlp> so over it.
2015-08-08T01:25:54 < zyp> even for stuff without crypto?
2015-08-08T01:26:13 < karlp> and all we can talk about in the nws is, "oh noes, russia might not buy makril! we should totes back down onon this sanctions thing"
2015-08-08T01:26:28 < karlp> don't care any morewhether it's crypto or not.
2015-08-08T01:26:40 < zyp> I bought a bunch of stuff from mouser the other day
2015-08-08T01:26:47 < karlp> we're not any the export list any more, I'm tired of trying to even find out what sort of bullshit reason digikey has.
2015-08-08T01:26:51 < karlp> so I bought them all from mouser.
2015-08-08T01:26:54 < zyp> f7-disco and nrf52-dk
2015-08-08T01:27:04 < karlp> oh, you go thte nrf52, nice.
2015-08-08T01:27:09 < zyp> nrf52 has crypto, so I had to sign some form for that
2015-08-08T01:27:14 < karlp> was looking at that, but it was a little more than I wanted to spend.
2015-08-08T01:27:21 < zyp> but no hassle apart from that
2015-08-08T01:27:28 < karlp> got a bunch of cheaper boards for diversity stuff.
2015-08-08T01:27:37 < zyp> yeah, idk what for
2015-08-08T01:27:44 < karlp> the nrf52 kit is in the "great big dev boards shopping cart"
2015-08-08T01:28:22 < karlp> I still have maybe 7 mrf24j40 modules I haven't mounated up on anything yet, what is this thing people talk about, actually having a project?!
2015-08-08T01:28:33 < zyp> I'm planning to do nrf51 stuff, and I'm pretty sure nrf51 would be better suited for what I want to do
2015-08-08T01:29:07 < zyp> because I need it to be small and cheap
2015-08-08T01:29:30 < zyp> the built in balun on nrf52 looks nice though
2015-08-08T01:30:04 < zyp> I think nrf51 is smaller, but if you need a balun, maybe the difference is irrelevant anyway
2015-08-08T01:30:40 < karlp> I watched a few minutes of nrf52 promo vide from some conference, iwt was like watching apple fan bois frothing
2015-08-08T01:31:14 < zyp> it's a shame it doesn't have usb
2015-08-08T01:31:27 < zyp> that was one of the interesting parts about that sam chip
2015-08-08T01:31:42 < zyp> I considered buying the board for that as well, but I dropped it
2015-08-08T01:32:30 < zyp> I guess maybe some stm32 and an nrf24l01 or something would be better suited as an usb adapter

2015-08-08T15:57:18 < dongs>  I got a tweet from joe saying after extensive testing 5-10 mins was the best it could do but did fly longer sometimes. Why did this come out after they had changed the flight times and website i think that was very underhand, we should start a petition get as many names on it as we can and see were we get I don't think it's unreasonable to get what I and so many others have paid for.

2015-08-08T16:07:38 < jadew> this is what I was originally checking out and noticed the $192 attached to it
2015-08-08T16:08:17 < jadew> I guess opensource developers get paid a shitload of cash when they're not doing it for free

2015-08-08T16:09:48 < jadew> they should motorize that
2015-08-08T16:15:57 < kakimir> no. traditional pedal system is superior
2015-08-08T16:21:09 < dongs> should  bother renewing matchboxarm.com

2015-08-08T16:52:14 < upgrdman> well that was fucking scary. riding the subway back to my hotel. two stops before home, the doors open and lights turn off. someone who spoke english tells me "this is the last stop."   ....  FML.   after a minute of quietly freaking the fuck out, i realize people just got out and queued back in line at the entrance doors. another subway came.
2015-08-08T16:52:55 < upgrdman> why the fuck do they kick people out before the end of the line?
2015-08-08T16:53:16 < dongs> haha
2015-08-08T16:53:48 < upgrdman> and why the fuck does  the subway close at 9:30pm when theres still fucktons of people trying to get around

2015-08-08T17:33:25 < PaulFertser> upgrdman: the reason might be very simple: they don't need that many trains during the evening hours, so they park away some. And the parking place is not always near the last stop. Probably those two sections were built years after the line was already on service.
2015-08-08T17:33:50 < upgrdman> mmmm ok
2015-08-08T17:36:52 < PaulFertser> Or sometimes more trains are needed in the central part of the line, so they make a "turn-around" (actually, it just goes to the third railway section in between the two regular ways and then goes backwards) at some suitable place.
2015-08-08T17:36:58 < PaulFertser> At least that's how moscow underground works.
2015-08-08T17:38:23 < PaulFertser> Two most common reasons to kick the people out. Less common is when a malfunction is detected in a train or its conductor (e.g. there was one occassion where the driver got literally too drunk to control the train).

2015-08-09T06:32:10 < mtbg> just accidentally watched one of these enthusiast-built emdrive videos on youtube
2015-08-09T06:32:39 < mtbg> guy shows that he has about 350mgf of thrust
2015-08-09T06:33:11 < emeb_mac> R2COM: latest stupid RF project -> http://ebrombaugh.studionebula.com/radio/hfsdr_proto/index.html
2015-08-09T06:33:13 < mtbg> too bad, he has the thrust in the opposite direction that emdrive paper claims
2015-08-09T06:34:36 < mtbg> he measures weight of his magnetron+cavity setup mounted vertically and gets lower value when the thing is on, but only after the buzz slightly changes, some seconds after the thing is turned on, and then this "thrust" starts to fade
2015-08-09T06:35:25 < mtbg> what I thing he just made a fancy looking bucket where he lights up plasma with his magnetron and then the bucket inflates and increases bouyancy
2015-08-09T06:35:54 < emeb_mac> yes
2015-08-09T06:37:02 < emeb_mac> that's just for basic audio demodulation - AM broadcasts or amateur SSB voice.
2015-08-09T06:37:52 < emeb_mac> amateur stuff is in specific bands scattered all over
2015-08-09T06:38:22 < emeb_mac> amateur stuff goes all the way to 30MHz

2015-08-09T06:39:08 < emeb_mac> actually a lot of it goes even higher, but this is mainly low freq

2015-08-09T06:44:03 < dongs> not alternating
2015-08-09T06:44:06 < dongs> its not even 'around' either

2015-08-09T06:44:17 < dongs> ugly
2015-08-09T06:44:26 < emeb_mac> the reason for that is they have single-row pmods
2015-08-09T06:44:31 < dongs> right
2015-08-09T06:44:36 < emeb_mac> and they want to do two on one dual conn
2015-08-09T06:45:16 < emeb_mac> the nice thing about standards is that there are so many to choose from.
2015-08-09T06:45:26 < jubatus> why did you chose a 10bit ADC ?
2015-08-09T06:45:36 < emeb_mac> jubatus: because it's cheap
2015-08-09T06:45:42 < emeb_mac> < $10
2015-08-09T06:45:56 < emeb_mac> good for proof of concept
2015-08-09T06:46:07 < emeb_mac> next iteration will likely be 14-bit
2015-08-09T06:46:13 < emeb_mac> for more dynamic range.
2015-08-09T06:47:18 < emeb_mac> R2COM: yeah - Samtec makes good stuff. I've used their impedance controlled connectors too.
2015-08-09T06:47:40 < emeb_mac> I've used them on 250MHz LVDS stuff
2015-08-09T06:48:00 < emeb_mac> Expensive tho

2015-08-09T15:09:48 < mitrax> atm i'm using a microchip RN41 but it's like $30 and the firmware is fucked up
2015-08-09T15:10:15 < PeterM> induction charging 3600mah at any decent speed is gonna be coockin
2015-08-09T15:10:25 < Sync_> not on their wabsite PeterM
2015-08-09T15:10:42 < Sync_> I know that they are planning to release the z4c but no hard details

2015-08-09T15:11:47 < PeterM> Sync_, yer my bad i was thinkin of the z3+ not the z3+c
2015-08-09T15:12:05 < Sync_> ye
2015-08-09T15:12:24 < Sync_> my ProblemFactory is, that I want a phone under 5" that is not from 3 years ago
2015-08-09T15:12:40 < PeterM> ^this
2015-08-09T15:12:55 < PeterM> at the same time though, i want a phone with mad hued battery
2015-08-09T15:13:00 < PeterM> huge
2015-08-09T15:13:02 < PeterM> even
2015-08-09T15:13:03 < mitrax> Rodio: the blueNRG looks nice but it's SPI
2015-08-09T15:13:08 < Sync_> which basically only leaves the z3c
2015-08-09T15:13:14 < PeterM> yer
2015-08-09T15:13:34 < mitrax> Rodio: ok my mistake, i should have said UART interface... SPI is serial as well :)
2015-08-09T15:13:35 < PeterM> tbh the z3c isnt that much smaller than lg g2 which i got
2015-08-09T15:13:45 < PeterM> so i was liek fuck it worth it
2015-08-09T15:14:23 < Rodio> it was random post, i joined now and i didn't have a clue what where you talking about

2015-08-09T17:28:20 < Laurenceb__> at least that might be real
2015-08-09T17:30:53 < Sync_> > 20 - 30 miles

2015-08-09T17:31:01 < Sync_> de fuk
2015-08-09T17:31:06 < Sync_> LOS obv
2015-08-09T17:31:07 < Sync_> but wat
2015-08-09T17:33:24 < Laurenceb__> no
2015-08-09T17:33:30 < Laurenceb__>  -130dBm sensitivity
2015-08-09T17:33:39 < Laurenceb__> so itd be over the horizon
2015-08-09T17:33:53 < Laurenceb__> in theory its _just_ possible
2015-08-09T17:34:01 < Laurenceb__> its supposed to be a 10kbps link
2015-08-09T17:34:40 < Laurenceb__> if they used 4PSK with a raw bit rate of ~50kbps
2015-08-09T17:34:54 < Laurenceb__> then a ton of FEC
2015-08-09T17:36:17 < Laurenceb__> but theres no off the shelf transceiver ic that comes close to managing anything like that
2015-08-09T17:36:36 < Laurenceb__> so I dunno if TBS could pull it off with lots of custom DSP
2015-08-09T17:39:58 < Laurenceb__> if they could make it work... why not just sell it as a datalink module
2015-08-09T17:39:59 < Laurenceb__> odd

2015-08-09T21:21:15 < Tectu> I try to understand whether alt_write_xxx() somehow handles unsigned vs. signed data types
2015-08-09T21:21:21 < Tectu> or if it just throws it onto the bus and does not care
2015-08-09T21:21:26 < Tectu> from what I can tell it just does not care
2015-08-09T21:21:54 < Steffanx> lovely

2015-08-09T21:34:18 < mtbg> why would it?
2015-08-09T21:35:05 < mtbg> signedness is not a property of information itself, only a way of its interpretation
2015-08-09T21:49:16 < Tectu> did somebody say ´fucked up sine´?  http://paste.ugfx.org/sores/7505d64a54e0/97ad4a92647a.jpg
2015-08-09T21:49:25 < Tectu> mtbg, indeed. makes sense
2015-08-09T22:03:17 < BrainDamage> look heavy exponential distortion
2015-08-09T22:03:39 < BrainDamage> plus the lovely glitch

2015-08-10T10:20:41 < zyp> well, I'm gonna start by asking wtf is up with delivering rev1 when they promised rev3
2015-08-10T10:21:00 < emeb_mac> hoping you wouldn't notice
2015-08-10T10:21:05 < dongs> lo'
2015-08-10T10:21:16 < zyp> yeah, right

2015-08-10T10:21:49 < zyp> would be nice if the boards just got assembled, and then I noticed it when they started crashing instead
2015-08-10T10:24:08 < mtbg> what's wrong with rev1?
2015-08-10T10:24:37 < dongs> read errata
2015-08-10T10:25:31 < zyp> mtbg, second half of flash is unusable without holding a certain pin low
2015-08-10T10:25:33 < zyp> PA12 IIRC
2015-08-10T10:25:44 < zyp> in my design PA12 is used for USB
2015-08-10T10:26:16 < zyp> and the whole reason I want to switch to F427 is for that second megabyte of flash
2015-08-10T10:28:05 < emeb_mac> that's such a strange erratum
2015-08-10T10:28:32 < zyp> yes, and fucking annoying
2015-08-10T10:29:31 < jpa-> on-par with the STM32F407 (or whatwasit) PDR_ON errata.. "hook this to Vdd" "no wait, we'll make it a GND pin on the next revision"

2015-08-10T14:06:28 < dongs> We also took delivery a few weeks back of a fully automated chip programmer, this programs the boot loader onto the main processor that Zano uses, re-reels the chips then when the EMS build's Zano's, they are already programmed ready to receive the OS. This machine is all setup and operational too.
2015-08-10T14:06:33 < dongs> lol zano

2015-08-10T14:14:48 < zyp> pre-programmed chips kinda sounds like a waste of time compared to just doing in-circuit programming
2015-08-10T14:18:02 < dongs> at zano volumes, probably
2015-08-10T14:22:01 < dongs> no idea what pic32 programming proces is
2015-08-10T14:22:08 < dongs> worst case they can load stuff into picki4 or whatever
2015-08-10T14:22:11 < dongs> which has standalone mode
2015-08-10T14:22:15 < dongs> and press, program, move on
2015-08-10T14:22:28 < dongs> don't see the need for expense on automatic programmer at all
2015-08-10T14:22:38 < jpa-> though if you can't program on-board without bootloader, definitely get the bootloader pre-programmed :D
2015-08-10T14:23:18 < dongs> A few things you may not be aware of, we have also built a fully automated test rig. It is a fully automated testing and calibration rig for Zano's. I'll try and post photos later. This device will tune each Zano as well as test every single function to ensure the very best quality product and the fewest if any faulty units. This test rig project is substantial in itself.
2015-08-10T14:23:41 < dongs> if they already have this (for whatever reasons), i dont see why this can't be extended into flashing initially too.
2015-08-10T14:23:53 < dongs> but most likely its just bullshit, like they've been feeding for months.

2015-08-10T14:45:33 < zyp> there are still no micro A sockets, the design means that B plugs will fit anywhere where A plugs fit
2015-08-10T14:46:21 < Tectu> type-c is something you can´t use with an intermediate chip that controls the stuff, right?
2015-08-10T14:46:24 < jpa-> why do they have separate A/B plugs anyway?
2015-08-10T14:46:41 < jpa-> i mean, separate micro A / micro B
2015-08-10T14:47:10 < PeterM> so you cant plug a otg dongle into a device that doesnt support otg
2015-08-10T14:48:27 < zyp> yeah
2015-08-10T14:48:39 < zyp> which of course don't work, since everybody uses micro B for OTG

2015-08-10T14:58:33 < Tectu> zyp, Load Capacity 12.5 pF. that is not the actual value of the two caps, right?
2015-08-10T14:58:50 < Tectu> there is some crazy math magic behind that, no?
2015-08-10T14:59:11 < dongs> Tectu: they arrived
2015-08-10T14:59:16 < dongs> silicone wire is so smooth
2015-08-10T14:59:18 < zyp> Tectu, correct
2015-08-10T14:59:20 < dongs> very impres
2015-08-10T14:59:31 < Tectu> dongs, so worth the 12 bucks?
2015-08-10T14:59:34 < dongs> y
2015-08-10T14:59:37 < Tectu> dongs, thanks
2015-08-10T14:59:43 < Tectu> dongs, did you draw blood yet?
2015-08-10T14:59:51 < dongs> i can now probe like a pro
2015-08-10T14:59:51 < zyp> Tectu, rule of thumb is that load capacitance should be twice the C_L value
2015-08-10T14:59:53 < Tectu> zyp, how do I determ the cap values?
2015-08-10T15:00:03 < Tectu> zyp, thanks!
2015-08-10T15:00:10 < zyp> so like 25pF, might subtract a little to account for trace capacitance
2015-08-10T15:00:25 < zyp> I usually just round down to the closest common value
2015-08-10T15:01:19 < Tectu> so 24 pF will do
2015-08-10T15:01:23 < Tectu> thank you for your help, zyp!
2015-08-10T15:02:08 < Tectu> 5% tollerance is 0.3 USD, 2% tollerance is 1.12 USD
2015-08-10T15:02:33 < Tectu> that does not really matter for an RTC for a clock, right? After all the crystal is crap too. It all comes down to calibrating the thing through the RTC registers?
2015-08-10T15:02:57 < zyp> eh, trace capacitance is probably more than 5%
2015-08-10T15:03:03 < zyp> so it's not a huge factor

2015-08-10T21:38:25 < mtbg> how is __HAL_LOCK from ST library supposed to work? only case that I can think of is protection from corrupting data structures/registers when the same peripheral or peripheral structures were accessed in thread mode and then an interrupt occured
2015-08-10T21:39:14 < mtbg> but most of the interrupts require some action on the peripheral registers to clear interrupt flag
2015-08-10T21:39:58 < mtbg> which, if done using HAL, may actually not happen since the __HAL_LOCK breaks the whole subroutine when it can't acquire "lock"

2015-08-11T03:38:54 < artag> I'm just starting to experiment with some stm32 discovery boards, and something's broken. can't connect using st-link any more. anyone willing to talk me through it ?
2015-08-11T03:39:15 < artag> i'm using smt32f3 discovery on linux
2015-08-11T03:40:56 < BrainDamage> check lsusb, check the device file in /dev, it should be a serial usb device, and check that you have rw permissions on it, you might hav an udev rule that remaps / symlinks it

2015-08-11T03:42:08 < artag> i do have a udev rule, but that allows me to flash it without being root
2015-08-11T03:42:14 < artag> i assume it's doing the right thing
2015-08-11T03:42:49 < artag> stuff changed when I tried to flash a new image (built from some different configs)
2015-08-11T03:43:09 < artag> the previous code is still running but the st-link is odd
2015-08-11T03:43:25 < artag> I get

2015-08-11T03:54:16 < artag> found this on github and it worked :
2015-08-11T03:54:17 < artag> What worked for me was:
2015-08-11T03:54:17 < artag> 1. Short the BOOT0 pin with VDD
2015-08-11T03:54:17 < artag> 2. Reset the board
2015-08-11T03:54:18 < artag> 3. st-flash erase
2015-08-11T03:54:28 < dongs> yeah.
2015-08-11T03:54:30 < artag> so what was goung on there ?
2015-08-11T03:54:43 < dongs> you wrote firmware that was locking it up
2015-08-11T03:54:50 < dongs> another thing that would most likely work is holding reset
2015-08-11T03:54:52 < dongs> doing st-flash erase
2015-08-11T03:54:54 < dongs> tehn releasing reset
2015-08-11T03:54:56 < dongs> button
2015-08-11T03:55:10 < dongs> by shorting boot0->vdd you basically entered rom bootloader instead of your buggy code
2015-08-11T03:55:18 < artag> right. so the st-link needs to talk to working code ?
2015-08-11T03:55:22 < dongs> no
2015-08-11T03:55:30 < dongs> but your code was so broken it killed SWD
2015-08-11T03:55:32 < dongs> which disco is this?
2015-08-11T03:55:33 < dongs> F3?
2015-08-11T03:55:37 < artag> yes
2015-08-11T03:55:40 < dongs> maybe you set AF to turn off SWD

2015-08-11T05:47:50 < jadew> *yes
2015-08-11T05:48:45 < jadew> after you enter the critical section anything goes
2015-08-11T05:48:57 < jadew> granted the other thread (the main one) respects it too

2015-08-11T05:49:55 < jadew> you can pass reference to buffers as long as you guarantee that you won't touch them and they're allocated by new
2015-08-11T05:51:08 < jadew> ok, so here's what you have to make sure: never access the same data at the same time
2015-08-11T05:51:12 < jadew> that goes for pointers too
2015-08-11T05:51:32 < jadew> so if you do char * buff = new char[1000];
2015-08-11T05:52:04 < jadew> enter_critical_section() pass buff to main leave_critical_section(); and then never touch the contents of the buffer again
2015-08-11T05:52:06 < jadew> you're fine
2015-08-11T05:52:16 < jadew> but you're relying on the main thread to delete [] it
2015-08-11T05:52:40 < jadew> a better way of ding this would be to use a unique_ptr
2015-08-11T05:53:01 < jadew> and pass it to the main thread after you enter the critical section
2015-08-11T05:53:39 < jadew> sure, that works too

2015-08-11T06:04:38 < mtbg> nope, just normal current shunt resistor to I/V conversion
2015-08-11T06:06:23 < jadew> ok, highest value resistor I stock seems to be 10 M
2015-08-11T06:06:40 < jadew> let me find the datasheet of the ucurrent
2015-08-11T06:07:24 < mtbg> http://www.eevblog.com/files/uCurrentRev5schematic.pdf
2015-08-11T06:08:05 < jadew> alright, so I should get 1pA resolution from this :)
2015-08-11T06:08:32 < mtbg> Ibias = 0.01nA
2015-08-11T06:08:40 < mtbg> of MAX4239
2015-08-11T06:08:44 < jadew> hmm
2015-08-11T06:08:56 < jadew> well, that's good
2015-08-11T06:09:42 < jadew> cuz 1V / 10 M = 100 nA so I should get 100 mV
2015-08-11T06:09:50 < jadew> let me set it up
2015-08-11T06:12:54 < dongs> sup dongs
2015-08-11T06:16:47 < mtbg> there are opamps with input current of tens of fA
2015-08-11T06:17:28 < jadew> ok, so I'm reading 99.4-99.5 the last two digits are all over the place
2015-08-11T06:17:48 < jadew> a handheld DMM
2015-08-11T06:18:08 < jadew> 5.5 digits
2015-08-11T06:18:12 < jadew> BM867
2015-08-11T06:19:09 < jadew> I get 100 pA of useful resolution
2015-08-11T06:19:57 < jadew> yeah, but as I was saying, it's all over the place
2015-08-11T06:20:20 < jadew> however, I get 100 pA of resolution from 1 mV change in input
2015-08-11T06:20:42 < jadew> yeah
2015-08-11T06:21:09 < jadew> me neither
2015-08-11T06:21:27 < jadew> a lab PSU
2015-08-11T06:21:31 < mtbg> you can always add two more resistors
2015-08-11T06:21:36 < mtbg> and have a voltage divider
2015-08-11T06:21:45 < jadew> it goes fairly low
2015-08-11T06:22:04 < jadew> at 10 mV I'm still getting a decent reading
2015-08-11T06:22:37 < jadew> ok, so seems to work down to 2 mV
2015-08-11T06:22:44 < jadew> at least that's what my PSU says
2015-08-11T06:22:53 < jadew> I'll have to measure the actual voltage, give me a sec
2015-08-11T06:25:15 < jadew> 3 mV after which the PSU drops to 0
2015-08-11T06:25:27 < jadew> oh wait
2015-08-11T06:25:29 < jadew> wire went loose
2015-08-11T06:26:08 < jadew> ok, so PSU can go lower, uCurrent can't
2015-08-11T06:26:40 < jadew> yeah, above 2 mV, at 2 mV is flat
2015-08-11T06:26:44 < jadew> at 3 mV it works
2015-08-11T06:27:37 < mtbg> I think uCurrent is symmetrical regarding 0
2015-08-11T06:27:38 < jadew> yeah
2015-08-11T06:27:46 < mtbg> so why would 0 be special?
2015-08-11T06:27:56 < jadew> mtbg, I'm not so sure it is
2015-08-11T06:28:01 < jadew> it runs from a single battery
2015-08-11T06:28:02 < dongs> emmc socket is here
2015-08-11T06:28:09 < dongs> time to ruin sony precision engineering
2015-08-11T06:28:18 < jadew> I think it's positive only, but I can give it a try
2015-08-11T06:28:28 < mtbg> single battery, but take a look at the schematic
2015-08-11T06:28:33 < mtbg> it has virtual gnd
2015-08-11T06:28:38 < mtbg> at Vbat/2
2015-08-11T06:28:49 < jadew> in reverse I'm getting garbage
2015-08-11T06:28:54 < mtbg> and measures in reference to it
2015-08-11T06:29:50 < jadew> well, you can have resolution of 100 pA
2015-08-11T06:29:59 < jadew> not sure what's the accuracy
2015-08-11T06:30:10 < jadew> 0.05% on the nA range
2015-08-11T06:30:14 < jadew> that's very good
2015-08-11T06:30:31 < jadew> R2COM, maybe in better measuring conditions
2015-08-11T06:31:03 < jadew> like.. if you had a proper current source feeding the plugs directly
2015-08-11T06:31:12 < jadew> 0.2-3 mV
2015-08-11T06:31:31 < jadew> the other digits fluctuate
2015-08-11T06:31:44 < jadew> so the fact that I'm getting pA resolution means nothing
2015-08-11T06:31:51 < mtbg> 2µV max offset, it then gets amplified by 100, so 200µV output offset max, and if it is 1nA/1mV, then you have 200pA error max from the offset itself
2015-08-11T06:31:57 < jadew> the digit right after the . is the only useful one
2015-08-11T06:32:11 < mtbg> there is also error from that input bias of ~10pA
2015-08-11T06:32:18 < mtbg> talking about absolute errors
2015-08-11T06:33:51 < jadew> mtbg, that's very little and wouldn't even show up on the meter as signifiant
2015-08-11T06:34:12 < jadew> since that kind of error would show up in the last digit on a 5.5 meter
2015-08-11T06:34:36 < dongs> zyp: rev3 confirmed
2015-08-11T06:34:57 < jadew> yeah

2015-08-11T06:35:21 < jadew> R2COM, yeah, that's what I'm getting
2015-08-11T06:35:27 < jadew> yes, but I can't rule out my setup
2015-08-11T06:35:43 < jadew> because I can't guarantee I'm putting a constant 1.000000 in
2015-08-11T06:36:03 < jadew> 1%
2015-08-11T06:36:39 < jadew> also, keep in mind that if a change of 1 mV generates a change of 100 pA, this noise could come from the PSU too
2015-08-11T06:36:54 < jadew> or from the environment really
2015-08-11T06:37:02 < dongs> http://i.imgur.com/VDtshLM.png
2015-08-11T06:37:04 < jadew> 0.000something mV is easy to pick up
2015-08-11T06:37:05 < dongs> zyp: http://i.imgur.com/VDtshLM.png
2015-08-11T06:37:07 < jadew> R2COM, yeah
2015-08-11T06:37:54 < mtbg> I'd put a voltage divider, 1:100 or something on the psu output
2015-08-11T06:38:31 < jadew> let's try it
2015-08-11T06:41:05 < jadew> 100 / 10k or 1k / 100k?
2015-08-11T06:41:49 < jadew> ah
2015-08-11T06:41:56 < jadew> hmm
2015-08-11T06:41:58 < jadew> why?
2015-08-11T06:42:03 < mtbg> it doesn't really matter
2015-08-11T06:43:00 < mtbg> load impedance is 10M if you keep that 10M resistor in place
2015-08-11T06:43:17 < mtbg> and 100k/1k divider has output impedance of <1k :>
2015-08-11T06:43:49 < jadew> wouldn't it be 100k?
2015-08-11T06:44:14 < mtbg> 100k in parallel with 1k is slightly less than 1k
2015-08-11T06:44:26 < jadew> yeah, but it's not in paralel is it
2015-08-11T06:44:42 < mtbg> considering impedance, it is

2015-08-11T06:47:01 < jadew> ok, so 1/100 voltage divider and 10 M shunt
2015-08-11T06:47:45 < jadew> 2 V in, I get 1.7-1.8 mV out
2015-08-11T06:47:56 < jadew> the other two digits are all over the place
2015-08-11T06:49:29 < jadew> very noisy, let me try higher
2015-08-11T06:50:03 < mtbg> is this noise coming on the input?
2015-08-11T06:50:19 < mtbg> i.e. does it stops when input is shorted?
2015-08-11T06:50:31 < jadew> good point, let's see
2015-08-11T06:50:58 < jadew> does not
2015-08-11T06:51:30 < jadew> with a metal thingie
2015-08-11T06:51:33 < mtbg> are you shoring it directly on the uCurrent input?
2015-08-11T06:51:37 < jadew> yeah
2015-08-11T06:51:52 < jadew> if I short the meter leads there's no noise
2015-08-11T06:52:20 < mtbg> that would not help :>
2015-08-11T06:52:31 < jadew> on resistor input I also have a cap to ground
2015-08-11T06:52:39 < jadew> brb, kid woke up
2015-08-11T06:56:36 < mtbg> Low Noise: 1.5µVP-P from DC to 10Hz
2015-08-11T06:56:47 < mtbg> if this is amplified 100x
2015-08-11T06:57:07 < mtbg> then, well, 0.150mVp-p noise on output
2015-08-11T06:57:17 < mtbg> from DC to 10Hz
2015-08-11T06:57:18 < jadew> back
2015-08-11T06:57:55 < jadew> yeah, the noise is definitely from uCurrentfrom the
2015-08-11T06:59:09 < jadew> I guess you could get 1 pA resolution through oversampling
2015-08-11T06:59:27 < jadew> but you need a better meter for that
2015-08-11T06:59:46 < jadew> well, this one can do it too, but it would take too long with 5 readings / second
2015-08-11T07:00:19 < jadew> I'm wrapping it up
2015-08-11T07:00:36 < jadew> do you guys want me to try anything else before I put it away?
2015-08-11T07:00:57 < jadew> R2COM, heh, yeah I didn't really need it, I just wanted to support his channel
2015-08-11T07:01:13 < jadew> some of the episodes are fun
2015-08-11T07:01:25 < jadew> R2COM, yeah
2015-08-11T07:01:44 < jadew> the smallest change I could notice was in the order of 100 pA
2015-08-11T07:02:07 < jadew> that's the least significant digit that was relatively stable
2015-08-11T07:02:07 < mtbg> which is 0.100mV on output
2015-08-11T07:02:09 < jadew> yeah
2015-08-11T07:02:27 < jadew> yes
2015-08-11T07:03:49 < jadew> not a bad idea, but I'm having water atm
2015-08-11T07:04:12 < jadew> saving the beer for a hot day

2015-08-11T07:10:57 < jpa-> hmph, my stm32-based alarm clock failed to wake up again.. second day in a row :P
2015-08-11T07:11:21 < jpa-> i wonder where the bug is, seems to happen at high uptimes but can't figure out any counter overflow that could be it
2015-08-11T07:13:04 < jadew> I suppose having it wake up in 5 minutes works?
2015-08-11T07:13:44 < jpa-> have to test more when i get home, but yeah, usually it works the next time
2015-08-11T07:13:56 < jpa-> now i was surprised that it didn't work yesterday, and also didn't work today
2015-08-11T07:14:24 < jpa-> IIRC it was about a year since previous fail
2015-08-11T07:14:54 < jadew> you can speed things up
2015-08-11T07:14:55 < jpa-> connected with USB, processor had not reset (uptime counter), RTC is set, wakeup time is set correctly

2015-08-11T07:23:05 < jadew> cheap!
2015-08-11T07:23:07 < dongs> less than I would spend making a breakout board

2015-08-11T08:27:59 < mtbg> actually I can think of one use case of negative memory adresses, where you need two independent memory "banks" without having explicit upper limit on their size and without wasting address ranges in your memory space
2015-08-11T08:29:46 < mtbg> "stack" effectively works as negative address based memory, when consecutive allocations of data objects on stack result in lower and lower addresses
2015-08-11T08:30:32 < mtbg> but well, I think it is pretty exotic example
2015-08-11T08:33:16 < mtbg> nonetheless, stack often grows "upwards" and heap grows "downwards" and they both share the same memory space, and don't have "explicit" limit because of this

2015-08-11T12:41:30 < Laurenceb> just need to work out how to control hatching orientation
2015-08-11T12:42:42 < jpa-> if you want vector hash, you can perhaps create a grid (extensions->render->grid) rotate and cut that using your path
2015-08-11T12:43:57 < Laurenceb> what is "vector hash"?
2015-08-11T12:44:04 < Laurenceb> too much weird terminology here
2015-08-11T12:44:16 < jpa-> i think the usual inkscape fills are rendered as bitmaps
2015-08-11T12:44:23 < Laurenceb> oh
2015-08-11T12:44:31 < Laurenceb> thats majorly annoying
2015-08-11T12:44:38 < jpa-> (fill patterns, that is)
2015-08-11T12:45:32 < jpa-> not 100% sure though
2015-08-11T12:45:54 < Laurenceb> i get the idea

2015-08-11T12:48:32 < Laurenceb> so i want the intersection of the grid and my shape?
2015-08-11T12:49:11 < jpa-> i think you want to put your shape on top (bring to front) first and then apply "cut" to them
2015-08-11T12:49:31 < jpa-> intersection is a "solid" operation so if the grid only has lines the result may be funny-ish
2015-08-11T12:50:18 < Laurenceb> hmm
2015-08-11T12:50:25 < Laurenceb> how do i "apply cut"?
2015-08-11T12:50:36 < jpa-> path->cut.. or is it path->divide
2015-08-11T12:50:37 < Laurenceb>  "cut path" does nothing
2015-08-11T12:50:48 < jpa-> should do
2015-08-11T12:50:56 < jpa-> your grid should now be two grids :P
2015-08-11T12:51:58 < Laurenceb> hmm
2015-08-11T12:52:05 < Laurenceb> maybe i need to rethink this
2015-08-11T12:52:22 < Laurenceb> perhaps i could use gimp then bitmap to vector
2015-08-11T12:52:36 < Laurenceb> or pay a graphic designer top do it for me
2015-08-11T12:53:25 < jpa-> inkscape has the funny fill tool also :)

2015-08-11T15:48:45 < jpa-> https://github.com/dekuNukem/Amazon_Dash_Button   that's a lot of HW capability compared to what it does
2015-08-11T15:49:27 < jpa-> if they keep subsidizing those at $5, i bet it will become quite popular platforms for hacks
2015-08-11T15:50:46 < dongs> wat the heck is it
2015-08-11T15:51:18 < jpa-> apparently it is a "button" that amazon sells.. you hold a button, speak what you want and voice recognition delivers it to your door
2015-08-11T15:51:35 < karlp> what? no speech recog in the dash button I thought
2015-08-11T15:51:42 < karlp> it was just one button, orders one product,
2015-08-11T15:51:49 < dongs> it has a mic
2015-08-11T15:51:56 < dongs> maybe thats for amazon to spy on you
2015-08-11T15:52:14 < karlp> you're meant to register each button to setup what product code you want it to buy.
2015-08-11T15:52:29 < mitrax> i thought that was an april's fool joke
2015-08-11T15:52:46 < jpa-> hmm.. indeed button is supposed to be single product
2015-08-11T15:52:49 < jpa-> why the mic :D
2015-08-11T15:53:12 < jpa-> got confused with the "dash device" that has speech
2015-08-11T15:54:18 < mitrax> that sounds retarded
2015-08-11T15:55:56 < emeryth> the mic is for configuring it
2015-08-11T15:55:56 < jpa-> probably they are planning to have speech recog on dash button also but need zyp to optimize it for them first

2015-08-11T15:57:03 < jpa-> custom fw
2015-08-11T15:57:07 < dongs> isnt it just STM32
2015-08-11T15:57:13 < jpa-> yea
2015-08-11T15:57:18 < dongs> so you can just make it do wahtever
2015-08-11T15:57:18 < dongs> heh
2015-08-11T15:57:27 < emeryth> Place your Dash Button near the bottom of your iPhone. Your Dash Button will receive ultrasonic tones from your iPhone to complete setup. This may take up to one minute.
2015-08-11T15:57:33 < jpa-> i bet the amazon fw uses stdhivperiph

2015-08-11T16:39:48 < dongs> well
2015-08-11T16:39:51 < dongs> depends where interrupt is
2015-08-11T16:39:55 < dongs> and stm32 part.

2015-08-11T16:50:44 < mitrax> Laurenceb: what's that?
2015-08-11T16:51:06 < Laurenceb> an annoying plot ive been trying to retouch in inkscape for hours
2015-08-11T16:51:16 < Laurenceb> ended up manually hatching it
2015-08-11T16:53:14 < jpa-> why hatch anyway?
2015-08-11T16:53:42 < mitrax> damn 100mA operating current, didn't realize it was that much
2015-08-11T16:53:50 < jpa-> seems like it could be better with simple color/grayscale fills
2015-08-11T16:55:05 < Laurenceb> jpa-: that doesnt print well
2015-08-11T16:55:20 < Laurenceb> although I might have gone too small with my hatching.. dunno
2015-08-11T16:55:31 < Laurenceb> need to speak to publishers :-/
2015-08-11T16:56:02 < Laurenceb> it has to be printable in crappy black and white quality
2015-08-11T16:56:28 < jpa-> well, with the border lines, it will be - you just need to have the legend in the same order so that one can know what is what
2015-08-11T16:56:46 < mitrax> would it be stupid to use a transistor on a GPIO line of the cpu to power on/off the SDRAM and other peripherals that needs to be put to sleep?
2015-08-11T16:57:14 < Laurenceb> cant SDRAM sleep by itself?
2015-08-11T16:57:20 < jpa-> mitrax: no, that is a quite common method - but you have to be careful with io pin states
2015-08-11T16:57:27 < qyx_> i did that for  microsd, gps and some weird radio modules
2015-08-11T16:57:39 < Laurenceb> yeah i do it for µSD
2015-08-11T16:57:50 < Laurenceb> but some cards are pretty good at sleeping by themselves
2015-08-11T16:58:40 < mitrax> jpa-: well as long as i use a high state i should be ok no?
2015-08-11T16:59:02 < jpa-> mitrax: sure
2015-08-11T16:59:17 < jpa-> especially if you can switch pins to high state before cutting off the power
2015-08-11T17:00:14 < mitrax> jpa-: okay thanks
2015-08-11T17:01:07 < mitrax> ahah nice the touchscreen controller only eats 1µA when idling
2015-08-11T17:01:24 < jpa-> ahahaha one

2015-08-11T19:06:53 < mitrax> am i misreading the manual or should i be able to wakeup from stand by with an avent on one of the tamper pins (if configured) i.e PC13/PI8 on STM32F4?
2015-08-11T19:07:20 < mitrax> i'm using PA0 / WKUP for UART already
2015-08-11T19:08:32 < jpa-> can't you wake up from standby with any pin configured as EXTI?
2015-08-11T19:08:39 < mitrax> no

2015-08-11T19:08:59 < mitrax> yeah that's kinda retarded the way they named it
2015-08-11T19:12:13 < zyp> mitrax, probably
2015-08-11T19:12:43 < zyp> tamper is one of the features in the rtc domain, so it's designed to be always active
2015-08-11T19:13:17 < zyp> wouldn't it be better to move the uart signal away from PA0 though?
2015-08-11T19:14:02 < mitrax> zyp: i can't, i'm using one uart with a bluetooth module already, the other one is for RS485, and the other uarts pins are taken by the LCD / SDRAM

2015-08-11T21:42:15 < ReadError> im sure the discovery schematic tells you the exact crystal and caps
2015-08-11T21:53:55 < gxti> the usual math to find load caps is double the crystal capacitance and subtract 5. so do that in reverse and you can get an estimate. but i suspect you're asking the wrong question.

2015-08-11T23:31:49 < mtbg> magnetron ignites plasma inside the bucket
2015-08-11T23:31:53 < mtbg> the bucket inflates
2015-08-11T23:32:12 < mtbg> and bouyancy change is misinterpreted as thrust
2015-08-11T23:32:30 < mtbg> due to the test setup which is probably a long arm pendulum

2015-08-11T23:34:26 < mtbg> notice that this "thrust" becomes apparent after the buzzing sound slightly changes, as if plasma discharge was ignited on the magnetron terminal inside the bucket

2015-08-11T23:36:48 < mtbg> the over/undershoot effect which is noticeable after switching power on and off seems to support this
2015-08-11T23:36:56 < mtbg> that the effect is thermal
2015-08-11T23:37:17 < mtbg> so I have alternative idea, just put a heater in the bucket
2015-08-11T23:38:26 < mtbg> what is more amazing is that this guy gets thrust in the opposite direction to that claimed in the official emdrive paper

2015-08-12T00:21:52 < mtbg> well, I think even properly evacuated vacuum test chamber has a lot of potential for misleading results, energy has to go somewhere, and it will always be turned into heat, even with extremely high-Q resonant cavity either the cavity, or the rf source will heat up, which will cause expansion
2015-08-12T00:22:08 < mtbg> and shift of the center of the mass
2015-08-12T00:23:04 < mtbg> relative to the support point

2015-08-12T02:38:55 < mitrax> atm i'm using the embedded STLINK on the STM32F429disco board, i want to get the same programming / debugging (with openocd) capabilities, SWIM and SWD aren't the same things are they?
2015-08-12T02:39:44 -!- KreAture_ is now known as KreAture_Zzz
2015-08-12T02:41:01 < mitrax> oh ok SWIM doesn't work for STM32
2015-08-12T02:42:08 < dongs> no it doenst
2015-08-12T02:42:23 < dongs> you dont even need nrst really
2015-08-12T02:42:24 < mitrax> so i guess i need SWCLK / SWDIO / NRST *and* SWO
2015-08-12T02:42:26 < dongs> just clk+io
2015-08-12T02:42:39 < mitrax> can i debug just the same without SWO?
2015-08-12T02:42:49 < dongs> i doubt opensores tools properly supports swo anyway
2015-08-12T02:42:59 < dongs> its for dumping data back from debug/trace unit
2015-08-12T02:43:29 < mitrax> okay, thanks
2015-08-12T02:44:23 < dongs> nrst isnt really needed either cuz y ou can reset over swd link too
2015-08-12T02:44:46 < dongs> just if your board is really hosed and you killed trace unit too, then you need reset but you can just manually hold reset button while connecting

2015-08-12T02:52:38 < mitrax> the st/link manual say to connect the st/link vdd with the target board mcu vdd to ensure signal compatibility, is it safe to connect them directly?
2015-08-12T02:52:44 < mitrax> say/says
2015-08-12T02:52:47 < zyp> it's pointless
2015-08-12T02:52:59 < dongs> stlink doesn't even do voltage sense does it?
2015-08-12T02:53:07 < zyp> not the onboard ones
2015-08-12T02:53:12 < zyp> standalone might, idk
2015-08-12T02:53:34 < zyp> if standalone has voltage buffers, it might even be required
2015-08-12T02:53:48 < zyp> but since we're talking about onboard now, that's irrelevant
2015-08-12T02:54:10 < mitrax> no no, i mean i'm making a board that will use the standalone ST/LINK
2015-08-12T02:55:03 < dongs> then put a standard cortex debug connetor on it
2015-08-12T02:55:04 < zyp> if you're making a board, I advise using the standard cortex debug connector, instead of making your own pinout
2015-08-12T02:55:05 < dongs> wiht al the pins
2015-08-12T02:55:12 < mitrax> ah
2015-08-12T02:55:18 < dongs> http://infocenter.arm.com/help/topic/com.arm.doc.faqs/attached/13634/cortex_debug_connectors.pdf
2015-08-12T02:55:23 < dongs> take your pick, either 10pin or 20pin one
2015-08-12T02:55:36 < dongs> bbl
2015-08-12T02:55:45 < zyp> you probably want the 10pin one
2015-08-12T02:56:25 < mitrax> great, thanks :)
2015-08-12T02:57:40 < zyp> unless you really care about JTAG mode, you can omit the TDI pin, but I would connect all the other pins
2015-08-12T02:58:19 < zyp> SWO/TDO can also be omitted if you don't care about trace, but it might come in handy in the future
2015-08-12T02:58:58 < mitrax> yeah i'm planning to connect the SWO pin even if i don't use it at first
2015-08-12T02:59:01 < zyp> assuming you're not designing for a cortex-m0, which only supports swd without swo, and thus has neither of those
2015-08-12T03:01:16 < mitrax> no it will me cortex-M4 and above, what's the standard name of that cortex debug connector?
2015-08-12T03:01:29 < mitrax> looks like a miniature HE10 or something
2015-08-12T03:01:52 < zyp> the connector itself is a standard 1.27mm pitch header
2015-08-12T03:02:16 < zyp> I prefer the shrouded ones, the pins are so easy to bend on unshrouded ones
2015-08-12T03:05:05 < zyp> http://www.digikey.no/product-detail/en/20021521-00010T1LF/609-4054-ND/2414951 <- I think these are the ones I'm usually using
2015-08-12T03:06:16 < mitrax> perfect
2015-08-12T03:06:17 < mitrax> thanks
2015-08-12T03:09:36 < mitrax> then i guess i need something like this http://microcontrollershop.com/product_info.php?products_id=4650 if i don't want to bother making my own... cheap enough

2015-08-12T03:11:10 < zyp> yes, assuming you don't have debug hardware with the same kind of connector
2015-08-12T03:11:43 < mitrax> nope ST/LINK only has JTAG
2015-08-12T03:12:16 < mitrax> i mean the JTAG connector, with pins for SWD as well
2015-08-12T03:16:41 < zyp> karlp, «OpenOCD has support for the flash in the PSoC 4 family, but nothing (yet) for the flash» I think you've mixed up some words there
2015-08-12T03:21:46 < zyp> ACM descriptors looks correct at a glance
2015-08-12T03:22:01 < zyp> even uses IAD to group them
2015-08-12T03:22:13 < karlp> zyp: onboard stlink does do voltage detect,
2015-08-12T03:22:24 < karlp> and dongs, oocd supports swo nicely now,
2015-08-12T03:22:41 < karlp> (it doesn't _do_ anything with the voltage sense, but it senses it ;)
2015-08-12T03:22:56 < zyp> karlp, yes, but there's no voltage buffers that needs a reference
2015-08-12T03:23:35 < zyp> so it's pretty pointless to connect
2015-08-12T03:23:43 < karlp> you can see the voltage printed out?
2015-08-12T03:24:33 < karlp> not sure where I was going wit hthe psoc4 comment.  maybe I meant the kitprog dongle part? but the psoc4 only has a usb-serial bridge anyway,
2015-08-12T03:24:43 < karlp> and you can debug the core as any other m3.
2015-08-12T03:24:58 < zyp> I suspected you meant supports cpu but not flash
2015-08-12T03:25:24 < karlp> no, cpu support is independent of psco, that's just cm3, maybe I meant psoc4 flash support in oocd, but nto psco5?
2015-08-12T03:25:53 < zyp> idk
2015-08-12T03:26:02 < karlp> doesn't matter :)

2015-08-12T03:29:21 < zyp> common problem
2015-08-12T03:29:42 < zyp> I still haven't flashed anything to multiple of the discovery boards I have
2015-08-12T03:29:46 < zyp> and I'm still buying more
2015-08-12T03:29:53 < karlp> got home and my f103 board had arrive dtoo,
2015-08-12T03:30:07 < karlp> need to at leaast verify that one works so I can deal with aliexpress
2015-08-12T03:30:12 < karlp> bunch of bent pins.
2015-08-12T03:30:15 < zyp> I saw you mentioned the mini/micro combo on one of the boards too
2015-08-12T03:30:22 < zyp> ST are still doing that as well
2015-08-12T03:30:34 < karlp> yeah, the gecko board has mini for the dbeugger, and micro for the user port
2015-08-12T03:30:38 < zyp> they only use micro-AB for OTG ports, the rest is all mini
2015-08-12T03:30:46 < karlp> the l072 and f053 boards are mini for both,
2015-08-12T03:30:53 < zyp> yeah
2015-08-12T03:31:01 < zyp> and f7 have one mini and two micro
2015-08-12T03:31:06 < karlp> bleh
2015-08-12T03:31:14 < karlp> gecko kit had both cables in the box though,
2015-08-12T03:31:25 < zyp> that's convenient
2015-08-12T03:31:29 < karlp> and a single blister pack cr2032 :)
2015-08-12T03:31:52 < karlp> the TI tiva C board included an ethernet cable on a spring loaded real thingy, that was cute.
2015-08-12T03:32:08 < zyp> nrf52 also came with a cr2032
2015-08-12T03:32:30 < zyp> heh, I bought one of those cables once
2015-08-12T03:32:34 < karlp> the atmel board was super naked, just the pcb in foil in a box.
2015-08-12T03:32:47 < zyp> I've never actually use it, it's too short to be useful
2015-08-12T03:32:49 < karlp> gotta say I liked the psoc packaging though :)
2015-08-12T03:33:51 < zyp> this nrf52 board is actually kinda interesting, for some reason it has two swd ports
2015-08-12T03:34:29 < zyp> each with a cortex debug connector
2015-08-12T03:34:45 < zyp> they are labelled Debug out and Debug in, respectively
2015-08-12T03:35:05 < zyp> I guess one is for debugging external parts with the onboard debugger, and the other is for debugging the onboard part with external debuggers
2015-08-12T03:35:41 < zyp> pretty convenient since I prefer doing the latter rather than figuring out host side software for the onboard debugger

2015-08-12T04:15:10 < PeterM> i wonder how decent those intel atom server boards are for NAS applications
2015-08-12T04:15:18 < PeterM> i know atom is trash
2015-08-12T04:15:27 < PeterM> but for file server you dgaf about cpu
2015-08-12T04:16:04 < zyp> I'm not really impressed by this AMT shit, it's kinda unreliable, tends to change IP sort of randomly, since it piggybacks on one of the normal interfaces
2015-08-12T04:16:14 < Roklobsta> PeterM: plenty of off the shelf NAS's get by with Atoms.
2015-08-12T04:16:23 < dongs> can you get remote bios/console over it?
2015-08-12T04:16:58 < zyp> idk, I've only used web shit that gives me some power on/off/reset and boot selection shit
2015-08-12T04:17:04 < zyp> I don't think the latter work properly
2015-08-12T04:17:18 < zyp> and it tends not responding to the power on command either
2015-08-12T04:17:36 < PeterM> http://www.asrockrack.com/general/productdetail.asp?Model=C2750D4I#Specifications if this shit didnt cost an arm and a leg it owuld be half decent for DIY NAS
2015-08-12T04:18:08 < zyp> so I guess next time I'll buy something with proper IPMI with a dedicated port
2015-08-12T04:18:56 < zyp> board is neat otherwise though, OS runs from an msata ssd
2015-08-12T04:22:21 < karlp> what are you doing at home that ipmi is what you need?
2015-08-12T04:23:43 < zyp> well, when AMT won't execute the power on command properly, I have to get off my lazy ass and move to the other end of my apartment and push the power button
2015-08-12T04:25:55 < zyp> and if I fucked up network settings in the os or wanted to change bios stuff, remote console would be convenient too, so I don't have to plug in a monitor and a keyboard

2015-08-12T07:28:23 < mtbg> and the same way to temporarily disable it
2015-08-12T07:29:51 < jadew> R2COM, we discussed this before
2015-08-12T07:29:56 < Rickta59> windows 10 .. the new gerbil wheel to keep you from looking at other things
2015-08-12T07:29:56 < jadew> roughly the same kernel
2015-08-12T07:30:04 < jadew> different subsystems
2015-08-12T07:30:17 < jadew> well, not all of them, the win32 subsystem is the same
2015-08-12T07:31:43 < jadew> what's running win 10 is the descendent of Windows NT
2015-08-12T07:32:11 < jadew> which was at the base of all the windows operating systems since... well, Windows NT :)
2015-08-12T07:32:25 < Rickta59> thanks Dave Cutler .. thanks Digita
2015-08-12T07:32:27 < Rickta59> l
2015-08-12T07:32:31 < jadew> at its core, yes
2015-08-12T07:32:47 < jadew> it was always awesome
2015-08-12T07:33:03 < jadew> that I do not know
2015-08-12T07:33:08 < jadew> Vista used it too
2015-08-12T07:33:47 < jadew> the nt kernel is basically a set of APIs and functions that the bare OS is exposing
2015-08-12T07:33:58 < jadew> on top of that we then used to have win32
2015-08-12T07:34:05 < jadew> on top of which we had the UI of the OS
2015-08-12T07:34:33 < jadew> same thing applied for all of them up to win7
2015-08-12T07:35:35 < jadew> since win8 things got a bit fuzzy for me, but I believe there's just one more subsystem running, WinRT

2015-08-12T08:18:41 < mtbg> very interesting thread
2015-08-12T08:18:57 < mtbg> one of a kind
2015-08-12T08:20:03 < mtbg> how much the world would be different now, if Linus would become convinced that there was no point in making a monolithic kernel back then
2015-08-12T08:20:23 < jadew> not much, it would still be opensource
2015-08-12T08:20:35 < jadew> the problem with opensource is that it doesn't advance much
2015-08-12T08:20:54 < jadew> and whatever advances are done, they're in the form of new stuff, discarding old stuff
2015-08-12T08:21:20 < jadew> and in the end generating yet an incomplete replacement for some older and incomplete part
2015-08-12T08:22:02 < jadew> this trend hasn't changed since I came in contact with linux 15 or more years ago
2015-08-12T08:22:12 < mtbg> well, most people contribute open source for the joy of thinking, implementing and debugging itself, and probably implementing a whole new thing is more satisfying
2015-08-12T08:22:22 < jadew> care to guess what the problem is?
2015-08-12T08:22:37 < jadew> money.
2015-08-12T08:22:47 < jadew> even if someone is on the right track
2015-08-12T08:23:17 < jadew> finding the motivation to go the extra mile to generate a polished result is extremely hard
2015-08-12T08:23:38 < jadew> so they don't do it
2015-08-12T08:25:34 < dos_fan]> The real show stopper for the microkernel architecture back then was the context switching overheads involved in message passing (TLB related mostly).
2015-08-12T08:26:13 < dos_fan]> architecturally it makes sense, practicalities are another thing
2015-08-12T08:27:15 < mtbg> funny thing is that people were looking forward GNU kernel back then
2015-08-12T08:27:22 < mtbg> and they still are today

2015-08-12T08:30:21 < jadew> well, since 1990
2015-08-12T08:30:25 < dongs> i think it only runs on 386
2015-08-12T08:30:40 < jadew> and on the official page it says: The GNU Hurd is under active development. Because of that, there is no stable version. We mainly distribute the Hurd sources through Git. The latest release is GNU Hurd 0.6.
2015-08-12T08:31:06 < jadew> 25 years later and they still didn't get to a stable version?
2015-08-12T08:31:26 < dos_fan]> because microkernels don't really work

2015-08-12T08:44:03 < akaWolf> nope
2015-08-12T08:44:24 < akaWolf> microkernel can work as so good, as monolithic

2015-08-12T08:46:14 < dos_fan]> please name one commercially successful microkernel
2015-08-12T08:46:57 < akaWolf> the only reason, why there is no release Hurd is just a lack of active developers, since Linux is already exists

2015-08-12T08:48:06 < dos_fan]> the Mach found in MacOS is not a microkernel

2015-08-12T08:50:53 < akaWolf> link
2015-08-12T08:53:38 < dos_fan]> One way to avoid some of the overheads is take virtual addressing out of the equation.  If I'm not mistaken, some Minix's used a flat address space with segmentation (ala 386 style) as a replacement for memory protection.
2015-08-12T08:53:55 < mtbg> :>
2015-08-12T08:58:37 < akaWolf> overhead isn't a problem for modern PCs
2015-08-12T08:59:06 < Roklobsta> how do you get memory protection in a flat space?  MMU still?
2015-08-12T08:59:57 < dos_fan]> akaWolf: to be fair, I did say back then above.  We now have various hacks like global pages that persist in the TLB
2015-08-12T09:00:02 < jadew> Roklobsta, probably
2015-08-12T09:00:35 < dos_fan]> Roklobsta: x86 protected mode has a rarely used segmentation feature
2015-08-12T09:01:03 < dos_fan]> everyone just initialises the global descriptor table limits as 4GB code and data
2015-08-12T09:03:22 < jadew> virtual addressing is handled by the CPU, right?
2015-08-12T09:04:11 < dos_fan]> yes
2015-08-12T09:04:16 < jadew> I guess that's where the TLB comes into play

2015-08-12T09:08:12 < jadew> so the CPU could do without
2015-08-12T09:09:05 < dos_fan]> yes effectively turning off virtual memory
2015-08-12T09:09:22 < dos_fan]> in the days of Minix, TLB misses were very expensive
2015-08-12T09:09:48 < jadew> well, wiki says that the MMU handles the address translation
2015-08-12T09:10:06 < jadew> implying that the TLB is just a cache for faster translations
2015-08-12T09:10:32 < jadew> suggesting that older entries might not be in the cache anymore and they have to be resolved by the MMU
2015-08-12T09:11:12 < dos_fan]> ah I thought you asking is it handle by hardware with CPU
2015-08-12T09:11:46 < dos_fan]> that is what we call a TLB miss
2015-08-12T09:12:01 < jadew> I see
2015-08-12T09:14:04 < dos_fan]> when you switch context (as you would passing a message from one microkernel service to another) you need to invalidate that cache (if they live in different virtual address spaces)
2015-08-12T09:15:28 < dos_fan]> in the past on x86, reloading cr3 invalidated the entire damn thing
2015-08-12T09:15:51 < dos_fan]> these days you can do it selectively by range
2015-08-12T09:16:11 < dos_fan]> which is useful when you have things like a kernel or shared memory
2015-08-12T09:16:20 < dos_fan]> common to multiple address spaces
2015-08-12T09:17:37 < jadew> ah so the TLB is only useful for one address space
2015-08-12T09:19:08 < dos_fan]> for the most part.  you can mark pages are global meaning they live at the same virtual/physical address in different address spaces (no invalidation requires)
2015-08-12T09:19:39 < dos_fan]> anyway to much crap talk, not enough getting ready for work.  later
2015-08-12T09:19:47 < dos_fan]> too*
2015-08-12T09:19:56 < jadew> you say that these days the invalidation can be done selectively - does that mean that if you switch address space, you invalidate a page (so the cache gets reconstructed I guess) and then when you switch back to another address space for which the page was already in the cache
2015-08-12T09:20:07 < jadew> it doesn't get invalidated anymore?
2015-08-12T09:20:18 < jadew> as in... it knows that cache entry was for that address space
2015-08-12T09:20:35 < dos_fan]> exactly
2015-08-12T09:20:41 < jadew> that's interesting
2015-08-12T09:20:42 < jadew> thanks
2015-08-12T09:21:02 < dos_fan]> take something like a Linux kernel, it's mapped high at the same address in every virtual address space
2015-08-12T09:21:12 < dos_fan]> it gets marked as global
2015-08-12T09:21:47 < dos_fan]> no TLB flush required when switching to ring0 and or another context
2015-08-12T09:22:15 < jadew> which is why monolithic kernels have the advantage
2015-08-12T09:22:43 < dos_fan]> exactly
2015-08-12T09:22:46 < dos_fan]> you got it

2015-08-12T09:55:27 < PaulFertser> dos_fan]: if L4 is not commercially successful, I do not know what you call success then.
2015-08-12T09:56:45 < PaulFertser> jadew I tried to compile the very first GNU Screen version (circa 80s). And you know what? It's almost fully compatible with modern GNU/Linux. Talking about compatibility.
2015-08-12T09:57:23 < jadew> PaulFertser, but does the binary run?
2015-08-12T09:57:39 < jadew> I mean if you compiled it on an 80s Linux
2015-08-12T09:57:55 < jadew> and then tried to run it on a current linux?
2015-08-12T09:58:13 < PaulFertser> jadew: who cares about binaries? Why care?
2015-08-12T09:58:21 < jadew> because not everything is opensource
2015-08-12T09:58:30 < jadew> especially the things that matter the most
2015-08-12T09:58:37 < PaulFertser> Linux appeared only in 1993 or so, there was no Linux back then.
2015-08-12T09:58:52 < jadew> well, whatever nix was back then
2015-08-12T09:59:29 < jadew> anyway, I suppose your point is that they kept compatibility too, but they didn't
2015-08-12T09:59:39 < jadew> the opesnource world has no such concept

2015-08-12T10:01:01 < artag> generally, cross-platform compatibility is of more interest than binary compatibility
2015-08-12T10:01:07 < PaulFertser> dos_fan]: and BTW, Qubes OS resembles microkernel architecture a lot, it's just that they're using a very stripped down Linux kernels as driver daemons.
2015-08-12T10:01:32 < jadew> artag, not if you're a company making closed source stuff
2015-08-12T10:01:39 < jadew> which is where all the goodies come from
2015-08-12T10:01:47 < artag> no, I meant to the opensource developer
2015-08-12T10:01:51 < jadew> yeah
2015-08-12T10:02:04 < jadew> that's their main concern
2015-08-12T10:02:09 < artag> though that depends on what you consider goodies
2015-08-12T10:02:22 < jadew> working programs that do useful stuff :)

2015-08-12T10:03:47 < artag> I think I'm only short of fpga dev tools that are open source, and there's a little progress on that too
2015-08-12T10:05:05 < jadew> artag, Thunderbird got a callendar like... a few weeks ago
2015-08-12T10:05:31 < jadew> Outlook had that for a decade I think
2015-08-12T10:05:47 < artag> meh. I use a wiki.
2015-08-12T10:05:50 < PaulFertser> jadew: you're so missing the point.... "opensource developers" are not the only people who need cross-platform compatibility. Adoption of GNU/Linux systems by many major commercial entities speaks against you.
2015-08-12T10:06:06 < jadew> PaulFertser, no, it doesn't
2015-08-12T10:06:26 < jadew> companies don't use opensource for desktop stuff
2015-08-12T10:06:44 < jadew> they use the server parts of the system
2015-08-12T10:06:52 < artag> but they can, if they want. It's up to them.
2015-08-12T10:06:59 < jadew> which are developed and improved upon by paid developers from those companies
2015-08-12T10:07:11 < jadew> they're not the product of joe-nobody from his mom's basement
2015-08-12T10:08:14 < artag> do they need to be ? Most people with the skillset ARE paid developers. The advantage comes from all contributing to the same codebase
2015-08-12T10:09:09 < jadew> artag, yes
2015-08-12T10:09:26 < jadew> I mean, yes, you're right
2015-08-12T10:10:32 < jadew> the point I was trying to make is that companies don't care about delivering something when they deal with opensource
2015-08-12T10:10:41 < jadew> they care about using those resources
2015-08-12T10:11:00 < jadew> and when you're using you don't care about compatibility
2015-08-12T10:11:23 < jadew> when you're selling something and your business model relies on that, it does
2015-08-12T10:12:11 < jadew> in that sense, a company acts as a single individual when it gets involved with say... httpd
2015-08-12T10:14:57 < jadew> I'm very tired so I'm not sure if I make sense anymore, but I hope you get the point I'm trying to make
2015-08-12T10:15:48 < jadew> binary compatibility matters when you produce something marketable and it doesn't when you're using something free
2015-08-12T10:17:38 < PaulFertser> jadew: OS X runs on an opensource kernel. Android is mostly opensource too. So even "desktop stuff" is covered. I think you're majorly narrowing your view on software usefullness when consideringy only _your_ desktop usecase scenarios.
2015-08-12T10:19:09 < jadew> I think Android guarantees binary compatibility - no?
2015-08-12T10:19:50 < jadew> don't know about OS X
2015-08-12T10:20:33 < dongs>  PaulFertser> jadew: you're so missing the point.... "opensource developers" are not the only people who need cross-platform
2015-08-12T10:20:36 < dongs>                      compatibility. Adoption of GNU/Linux systems by many major commercial entities speaks against you.
2015-08-12T10:20:43 < dongs> do you know WHY those "commercial entities" "adopted" "gnu/lunix"?
2015-08-12T10:20:47 < dongs> because its fucking FREE AS IN AIDS
2015-08-12T10:20:55 < dongs> it doesnt HAVE TO WORK
2015-08-12T10:20:56 < dongs> its just free
2015-08-12T10:21:01 < dongs> and wiht some finite amount of dicking
2015-08-12T10:21:06 < dongs> it might even do what you want, somewhat
2015-08-12T10:21:10 < PaulFertser> But if it didn't work, they won't be able to use it.
2015-08-12T10:21:20 < jadew> anyway, there's always the chance that I'm wrong, but I don't really consider Android as having anything useful to offer
2015-08-12T10:21:30 < dongs> if there's a free / cheap commercial alternative with proper support, I can guaranfuckingtee you lunix trash will be dropped JUST LIKE THAT

2015-08-12T10:28:00 < dongs> it turns it into a useles fucking brick

2015-08-12T10:29:02 < emeb_mac> some dude on the news advocating that all "drones" imported into the US should be outfitted with cellphone tracking
2015-08-12T10:29:20 < emeb_mac> to allow law enforcement to trace them when they're used for illegal purposes.
2015-08-12T10:29:22 < mtbg> I have to say that the idea of using hardware sensor windowing for image stabilisation is quite smart
2015-08-12T10:29:56 < dongs> uh

2015-08-12T10:30:37 < artag> dongs: I mean, useful to people making stuff. sure, hacking a commercial product for some small feature change isn't often useful. Though it's very often done on things like routers, because the commercial feature set is either badly limited or expensive.
2015-08-12T10:30:46 < mtbg> given the hardware they have, that is the best option probably
2015-08-12T10:31:00 < dongs> mtbg, its useless except in the testcase they shown
2015-08-12T10:31:25 < dongs> i.e. direct straight pitch up/down
2015-08-12T10:31:29 < dongs> it will not correct roll

2015-08-12T10:31:40 < dongs> for actual FLYING device
2015-08-12T10:36:33 < mtbg> emeb_mac: wouldn't everyone who wants to use it for illegal purposes just remove or jam that tracker module?
2015-08-12T10:37:17 < emeb_mac> mtbg: of course. the dude on the news just says "Impose substantial penalties for "hacking".

2015-08-12T11:28:57 < jadew> companies in opensource are either users or abusers
2015-08-12T11:29:22 < jadew> they're users when they use a particular project (and can even contribute to it)
2015-08-12T11:29:55 < jadew> or abusers when they opensource their code so everyone can contribute, but they get ownership of every contribution
2015-08-12T11:30:22 < jadew> so in essence they get stuff done for free
2015-08-12T11:30:28 < PaulFertser> Agreed.

2015-08-12T13:51:47 < mitrax> hi there,on the STM32F429 discovery there's a powerswitch with overcurrent protection for usb OTG, it has an enable pin connected to PC4, when not enabled it has a protection so there's no reverse current  if you plug the board to a host supplying VBUS, are you supposed to sense VBUS and then immediately disable the chip by setting PC4 high?
2015-08-12T13:53:58 < mitrax> hmm i guess that would be if you powered the whole board from the host... which is not possible through the micro usb connector on the discovery, there won't be any reverse current as long as the board has its own 5V

2015-08-12T14:03:42 < mitrax> so supposedly HS can do 480Mbps and FS 12MBps?
2015-08-12T14:04:00 < dongs> Such is the nature of a Kickstarter project like this; you.re buying into making ZANO a reality rather than just picking a product off the shelf! With any other consumer electronic every little kink along the way, whether in development or logistics, has been faced and conquered before the product hits the market whilst here you.re on-board every step of the way throughout the development process!

2015-08-12T14:40:06 < zyp> mitrax, that's not completely true
2015-08-12T14:40:38 < zyp> HS USB is 480 Mb/s and FS USB is 12 Mb/s, yes
2015-08-12T14:41:07 < zyp> stm32f4 have two usb cores, one that's only FS capable, and one that's FS/HS capable
2015-08-12T14:41:27 < zyp> but to get the HS capability, you need an external HS PHY, connected by ULPI
2015-08-12T14:42:12 < zyp> the OTG_HS_DM/OTG_HS_DP pins are for the internal FS PHY of the FS/HS capable core, and when connecting to those, you only get FS mode
2015-08-12T14:42:52 < zyp> so FS and HS in that context is just differating the two internal cores, rather than the speeds of each
2015-08-12T14:43:02 < zyp> you can think of it like USB1 and USB2 respectively
2015-08-12T14:43:06 < mitrax> i see
2015-08-12T14:44:01 < mitrax> but both can act as host or peripheral, that's irrelevant of their speed right?
2015-08-12T14:45:54 < karlp> only the OTG core.
2015-08-12T14:46:51 < zyp> both are OTG cores
2015-08-12T14:46:54 < zyp> and yes
2015-08-12T14:47:08 < karlp> oh yeah, f4
2015-08-12T14:47:15 < mitrax> karlp: yeah :)
2015-08-12T14:47:25 < zyp> in host mode, they can both also run in LS mode, i.e. 1.5 Mb/s
2015-08-12T14:48:47 < zyp> all HS devices are supposed to support falling back to FS speeds (but some devices might not do anything useful at those speeds because 12 Mb/s would be too slow)
2015-08-12T14:49:01 < zyp> like webcams and such
2015-08-12T14:50:14 < mitrax> and the ID pin purpose is to distinguish what has been plugged  (host or peripheral) or am i misunderstanding something?
2015-08-12T14:57:37 < mitrax> aaah i get it

2015-08-12T14:58:31 < mitrax> hrm no, i was gonna say if ID is connected to the ground then you supply VBUS, but that's the other way around, ID to ground means host
2015-08-12T15:05:29 < mitrax> sorry for the retarded questions... i don't plan to implement USB in software yet (as you can figure i never messed with it) i just want to be sure there's nothing wrong with the board i'm putting together, i based the schematics on what i saw on the discovery board http://download.unfiltered.net/usb.png more or less
2015-08-12T15:07:24 < mitrax> it eludes me how i know when a peripheral has been plugged (with no VBUS, when the power switch is off) , is that handled by the USB core by detecting an impedance change on the DP / DM lines or something?
2015-08-12T15:12:24 < zyp> yes
2015-08-12T15:12:41 < zyp> 1.5k pullup on one of the data lines
2015-08-12T15:12:48 < zyp> it's also used to signal speed
2015-08-12T15:13:06 < zyp> pullup is on d+ for FS devices and d- for LS devices
2015-08-12T15:13:25 < zyp> HS devices initially identify as FS devices and negotiate HS afterwards
2015-08-12T15:14:27 < zyp> ID is grounded in A-side plugs and floating in B-side plugs

2015-08-12T15:14:54 < zyp> A-side is host and B-side is device
2015-08-12T15:15:35 < zyp> so if you have a micro-A to micro-B cable plugged between two OTG capable devices, the direction of the cable decides what is the host and what is the device

2015-08-12T15:51:51 < karlp> mitrax: if the device being plugged in is bus powered, there's no way for any pullups do do anything if you aren't providing vbus.

2015-08-12T18:15:52 < mitrax> dongs: i mean on the actual connector
2015-08-12T18:15:53 < dongs> yes
2015-08-12T18:15:55 < dongs> SDIO 1bit != SPI
2015-08-12T18:15:58 < dongs> mitrax: yes
2015-08-12T18:16:15 < mitrax> ok so NC it is, thanks
2015-08-12T18:16:20 < dongs> mitrax: DAT3 = NC. DAT1/2 = have overloaded functions, if you arent using them, NC
2015-08-12T18:17:15 < mitrax> and the card detection switch is not part of the 8 pins right? it's an additional pin if the connector has it?
2015-08-12T18:17:26 < dongs> different pin on connector.

2015-08-12T20:21:06 < Laurenceb_> so thats why MCUs dont tend to use cache
2015-08-12T20:21:09 < Laurenceb_> very annoying
2015-08-12T20:21:15 < emeb> "left as an exercise for the reader"
2015-08-12T20:21:25 < Laurenceb_> results with NoCache are very poor

2015-08-12T20:25:53 < Tectu> interesting
2015-08-12T20:26:38 < Tectu> jpa-, but afaik you can simply not turn the caching on?
2015-08-12T20:26:51 < Tectu> jpa-, at least in the ST examples I used they had to turn it on explicitely
2015-08-12T20:27:03 < jpa-> sure, and have crappy performance?
2015-08-12T20:27:24 < jpa-> looks like 2x slower for some of the memory-intensive tests

2015-08-12T20:29:27 < jpa-> you could probably run fast stuff from TCM and have the rest of the ram without cache
2015-08-12T20:29:40 < jpa-> but having stack that cannot be used for e.g. SPI buffers is quite annoying
2015-08-12T20:29:55 < Tectu> I am confused. how is not using the chache any slower compared to an M4? I assume that ´disabling the cache´ means that it is bypassed
2015-08-12T20:34:31 < Laurenceb_> why would you put spi buffer in cache?
2015-08-12T20:34:36 < Laurenceb_> surely a bad idea?
2015-08-12T20:34:39 < jpa-> i assume that the bus/ram connection in STM32F7 is not single-cycle.. so when you disable cache, it takes more clocks for any load/store
2015-08-12T20:34:55 < jpa-> Laurenceb_: in stack, and stack you would want to be in cache
2015-08-12T20:35:11 < Laurenceb_> i meant in stack
2015-08-12T20:35:24 < Laurenceb_> guess for some rtos stuff that might be a good idea?
2015-08-12T20:35:26 < Steffanx> Don't all cpu's with cache have similar issues?
2015-08-12T20:35:36 < jpa-> i don't know how you do stuff, but i find myself doing things like   uint8_t foobar[] = {CMD_1234, addr, value};  spi_send(foobar, sizeof(foobar));
2015-08-12T20:35:49 < Laurenceb_> that looks like tarduino code
2015-08-12T20:35:55 < qyx_> same here
2015-08-12T20:35:56 < jpa-> Steffanx: mostly yes, but most microcontroller don't have data cache for internal ram
2015-08-12T20:36:00 < Laurenceb_> unless spi_send is an rtos task
2015-08-12T20:36:13 < jpa-> Laurenceb_: nah, the code that calls that is rtos task of course
2015-08-12T20:36:20 < Laurenceb_> ok fairdoos
2015-08-12T20:36:30 < Laurenceb_> so then rtos can handler the cache issues
2015-08-12T20:36:34 < Laurenceb_> *handle
2015-08-12T20:36:52 < jpa-> handle them how? :P
2015-08-12T20:36:59 < Laurenceb_> I'd use a dedicated buffer in heap for spi :P
2015-08-12T20:37:04 < Laurenceb_> then dma it
2015-08-12T20:37:17 < Laurenceb_> but that doesnt solve cache issues :S
2015-08-12T20:37:29 < jpa-> yeah, would have to be a separate dma_malloc() or similar
2015-08-12T20:38:02 < jpa-> to allocate into a non-cached block of ram

2015-08-12T20:47:22 < zyp> «Question and more importantly, isn't the RAM supposed to work with zero wait states?»
2015-08-12T20:47:27 < zyp> sure the internal sram is
2015-08-12T20:47:43 < zyp> and if that's all you're gonna use, just disable the cache
2015-08-12T20:49:21 < zyp> cache is interesting when you're working with slower memories, i.e. external ones
2015-08-12T20:52:22 < jpa-> but based on results it seems that on STM32F7 the internal ram is not zero wait states? (i guess that is why they have TCM..)
2015-08-12T20:53:36 < zyp> true zero wait state memory is impossible when you have to have an arbiter to allow access for multiple masters

2015-08-12T21:05:06 < Ecco> Guys, quick question
2015-08-12T21:05:17 < Ecco> What should I do in a "sleep-like" function on an STM32
2015-08-12T21:05:28 < Ecco> Let's say I want to wait 100msec
2015-08-12T21:05:39 < zyp> what do you want to do while waiting?
2015-08-12T21:05:42 < Ecco> An idiotic way would be a huge for loop
2015-08-12T21:05:45 < Ecco> zyp: nothing
2015-08-12T21:05:52 < jpa-> do you need to save power?
2015-08-12T21:06:02 < zyp> Ecco, nothing is not a valid answer
2015-08-12T21:06:02 < Ecco> jpa-: yeah, that's pretty much the point
2015-08-12T21:06:13 < Ecco> zyp: Ok, then my question probably isn't worded right
2015-08-12T21:06:15 < jpa-> ok, so you want to save power while waiting
2015-08-12T21:06:21 < Ecco> jpa-: Indeed
2015-08-12T21:06:29 < Ecco> ok, let me rephrase
2015-08-12T21:06:31 < zyp> Ecco, either you want to put the cpu to sleep, or you want to keep it busy
2015-08-12T21:06:40 < jpa-> you can set up a timer to wake you up and run WFI instruction to save small amounts of power
2015-08-12T21:06:53 < jpa-> if you don't need peripherals running, you can go to lower power states also
2015-08-12T21:06:56 < Ecco> Ok
2015-08-12T21:06:59 < Ecco> makes sense
2015-08-12T21:07:02 < Ecco> let me rephrase though
2015-08-12T21:07:11 < Ecco> If I were to write my own RTOS for STM32
2015-08-12T21:07:24 < zyp> then you'd build this into the thread scheduler
2015-08-12T21:07:33 < Ecco> what should the "empty-task" (the task that gets scheduled when no other task wants CPU time) do?
2015-08-12T21:07:46 < jpa-> yeah, your scheduler would look like     something to run? run it. otherwise WFI.
2015-08-12T21:07:57 < Ecco> ok
2015-08-12T21:07:58 < zyp> you manage a queue of sleeping threads sorted by deadline
2015-08-12T21:08:18 < Ecco> in case of a deadline scheduler, indeed
2015-08-12T21:08:24 < Ecco> but I'm not talking about the scheduler per-se
2015-08-12T21:08:28 < Ecco> more about the "idle-task"
2015-08-12T21:08:32 < zyp> context switch happens in an ISR, so if you have nothing to switch to, you set the SLEEPONEXIT bit, which does the equivalent of WFI any time an ISR exits
2015-08-12T21:08:42 < Ecco> allright
2015-08-12T21:08:52 < zyp> so you won't even have an idle task, the cpu simply sleeps when it's done processing interrupts
2015-08-12T21:09:06 < Ecco> Ok, I had no idea ARM had such a thing as a the WFI instruction
2015-08-12T21:09:12 < zyp> until you're ready to wake up and switch to the next active task

2015-08-12T21:10:05 < Ecco> Thanks though guys, your answer was spot on :)
2015-08-12T21:10:11 < jpa-> Ecco: here you can see the idle task of the NuttX RTOS: https://github.com/projectara/nuttx/blob/master/nuttx/arch/arm/src/stm32/stm32_idle.c#L169
2015-08-12T21:10:56 < zyp> Ecco, sure it does, it's called STOP
2015-08-12T21:11:09 < zyp> (according to a quick google search)
2015-08-12T21:11:13 < Ecco> zyp: ok :-)
2015-08-12T21:11:25 < Ecco> I gues I never had to use it then
2015-08-12T21:11:35 < Ecco> jpa-: When we're on this topic: what do you think of nuttx?
2015-08-12T21:11:40 < zyp> lots of people never use WFI either
2015-08-12T21:12:20 < jpa-> Ecco: well.. nuttx does a lot (a lot more than most microcontroller operating systems, perhaps only retrobsd is on similar level)
2015-08-12T21:12:29 < jpa-> IMO it often does a bit too much
2015-08-12T21:13:02 < Ecco> I understand
2015-08-12T21:13:08 < jpa-> but i have used it in one particularly complex work project and was quite satisfied, had to fix a few bugs though
2015-08-12T21:13:09 < Ecco> Is the code reliable?
2015-08-12T21:13:16 < Ecco> ok!
2015-08-12T21:13:26 < jpa-> the core is quite reliable, the hardware drivers have very varying quality
2015-08-12T21:13:34 < Ecco> Makes sense
2015-08-12T21:13:42 < Ecco> What's its typical flash footprint?
2015-08-12T21:14:03 < jpa-> i'd say 100kB, though you can make it quite small with careful configuration
2015-08-12T21:14:15 < Ecco> allright
2015-08-12T21:14:19 < Ecco> that seems pretty nice
2015-08-12T21:14:46 < Ecco> thanks again!
2015-08-12T21:15:27 < jpa-> at the point when you need the nuttx features, you have to consider carefully if it might be simpler to just run linux
2015-08-12T21:15:37 < Laurenceb_> chibios can do WFI sleep by default
2015-08-12T21:16:00 < Laurenceb_> alternatively you could go hardcore and use RTC with alarm
2015-08-12T21:16:04 < zyp> jpa-, I put some thought into this cache issue
2015-08-12T21:16:09 < Laurenceb_> for very long sleeps where you dont mind losing memory
2015-08-12T21:16:14 < jpa-> yeah, pretty much every arm rtos does WFI sleep.. just that chibios has it hidden in macros so didn't have such a nice link :)
2015-08-12T21:16:19 < jpa-> zyp: ok?
2015-08-12T21:16:57 < zyp> jpa-, I'd say the responsibility for cache invalidation falls on the code that sets up the DMA transfer
2015-08-12T21:17:31 < jpa-> i feel the same, perhaps it should even be part of the dma start / dma end functions
2015-08-12T21:17:43 < zyp> since that code also is responsible for access arbitration to that particular memory area
2015-08-12T21:17:48 < zyp> yeah
2015-08-12T21:18:04 < zyp> the only problematic issue then is when you want to do continous/circular dma
2015-08-12T21:18:51 < zyp> but even so, it's the responsibility of the code that handles flow control between cpu and dma
2015-08-12T21:19:34 < zyp> F7 is actually kinda neat with respect to DMA
2015-08-12T21:19:51 < zyp> TCM blocks are available for dma through the AHBS port
2015-08-12T21:20:13 < zyp> unlike CCM on F4

2015-08-12T22:07:29 < jpa-> why is it french on .ch domain?
2015-08-12T22:07:44 < Tectu> because 40% of switzerland is french?
2015-08-12T22:08:02 < jpa-> mind blown
2015-08-12T22:08:05 < Tectu> well, when it comes to population it is probably pretty much 50% native german and 50% native french (mother tongue)
2015-08-12T22:08:10 < Tectu> oh wait, we also have about 5% native italian
2015-08-12T22:08:19 < jpa-> do you speak french?
2015-08-12T22:08:23 < Tectu> and a few people some other weird language called retromanisch
2015-08-12T22:08:26 < Tectu> yes
2015-08-12T22:08:39 < Tectu> my university is in the french part of switzerland

2015-08-12T22:08:56 < Tectu> lol
2015-08-12T22:09:16 < Tectu> I live in one of the cantons (that is a part of the country such as the Bundesland in germany) that is half german half french
2015-08-12T22:10:19 < jpa-> why don't you all just speak swiss

2015-08-13T00:31:15 < Tectu> man, I wish I would know RF magic
2015-08-13T00:31:34 < emeb> it's fun stuff
2015-08-13T00:31:44 < Tectu> yeah, I bet
2015-08-13T00:32:21 < emeb> actually not a whole lot of RF in that project - mostly digital / DSP
2015-08-13T00:32:28 < Tectu> emeb, is that yours?
2015-08-13T00:32:35 < emeb> Tectu: yes
2015-08-13T00:32:45 < Tectu> emeb, I see you mention some Display stuff... ;)
2015-08-13T00:33:05 < Tectu> someone did a simple spectrum analzyer with uGFX about three years ago
2015-08-13T00:33:12 < emeb> Tectu: yes - I think I saw it.
2015-08-13T00:33:29 < Tectu> emeb, are you considering using ugfx?
2015-08-13T00:33:48 < emeb> I've got my own bare-bones drivers for cheapo OLED and LCD graphics displays.
2015-08-13T00:33:52 < Tectu> this one is neat too: https://www.youtube.com/watch?v=WmpKC9ODH8c
2015-08-13T00:34:01 < emeb> nothing fancy but enough to make it work.
2015-08-13T00:34:16 < emeb> I tend to spend most of my effort on the DSP and low-level stuff.
2015-08-13T00:34:44 < ds2> interesting
2015-08-13T00:34:52 < Tectu> then using ugfx makes even more sense. if you have a working setup it is very easy to use uGFX. all you have to do is implement one file. functions to write to the display (read is optional)
2015-08-13T00:35:13 < ds2> emeb:have you looked at the iCE40 stuff?
2015-08-13T00:35:27 < emeb> ds2: I've got an icestick sitting on my desk here.
2015-08-13T00:35:35 < emeb> hope to fiddle with it soon.
2015-08-13T00:35:41 < ds2> emeb: would the fpga stuff fit into that?
2015-08-13T00:36:00 < ds2> there is suppose to be an alternative toolchain for the ice40
2015-08-13T00:36:30 < emeb> ds2: I very much doubt my DSP would fit in an ICE part. Too much high-speed math for the resources they have.
2015-08-13T00:36:49 < emeb> but yes - there is apparently a fully-open synthesis chain for it now.
2015-08-13T00:39:29 < Laurenceb_> http://cas.web.cern.ch/cas/Germany2009/Lectures/PDF-Web/Jensen.pdf
2015-08-13T00:39:34 < Laurenceb_> high power pron
2015-08-13T00:40:48 < Tectu> ds2, I used an ice40 in one of my projects
2015-08-13T00:41:05 < Tectu> ice40 is lowpower-lowcost stuff
2015-08-13T00:41:30 < Tectu> Laurenceb_, love slide nr. 4
2015-08-13T00:42:47 < Tectu> mainly because I don´t understand the rest of the presentation
2015-08-13T00:44:10 < Tectu> Laurenceb_, can you explain all that gaping to me?
2015-08-13T00:44:20 < Laurenceb_> lol
2015-08-13T00:44:30 < Laurenceb_> they are firing things down holes
2015-08-13T00:44:51 < Tectu> that´s the part I am familiar with
2015-08-13T00:45:07 < Laurenceb_> lulz
2015-08-13T00:45:11 < Laurenceb_> holy shit page 63
2015-08-13T00:45:14 < Laurenceb_> fapfapfap
2015-08-13T00:45:24 < Tectu> but why?
2015-08-13T00:45:27 < Tectu> lol´d
2015-08-13T00:51:39 < emeb> that's some big science right there.
2015-08-13T00:52:41 < ds2> Tectu: did you use the open toolchain?
2015-08-13T00:52:57 < Tectu> ds2, No idea whether is open. I used the ICECube2 thing
2015-08-13T00:53:11 < Tectu> that uses Synplify Pro for synthesis
2015-08-13T00:53:15 < ds2> yosys I think is the open tool
2015-08-13T00:53:44 < emeb> sounds right - the Lattice toolchain is not open.
2015-08-13T00:54:04 < ds2> I'd be happy with a perpetual toolchain
2015-08-13T00:54:26 < emeb> what do you mean by perpetual?
2015-08-13T00:54:55 < ds2> all the other toolchains requires you to renew the license on an annual basis
2015-08-13T00:55:30 < emeb> yep - pretty standard in EDA industry.
2015-08-13T00:55:32 < ds2> either you run the machine connected to the net or you need to go through a process
2015-08-13T00:55:44 < ds2> PSoC and the open toolchain doesn't require that
2015-08-13T00:55:55 < emeb> I'm still running Xilinx ISE 11.5 though - haven't renewed it since buying it in 2010
2015-08-13T00:56:05 < emeb> just don't get updates anymore.
2015-08-13T00:56:26 < ds2> buying it as in paid $$ for it?
2015-08-13T00:56:30 < emeb> yes
2015-08-13T00:56:46 < ds2> yes that's the alternative
2015-08-13T00:56:50 < emeb> was working on very large parts not supported by the free webpack.

2015-08-13T01:01:18 < ds2> emeb: what antenna are you using for HF?
2015-08-13T01:02:07 < emeb> ds2: I've just got a big wire loop in the attic
2015-08-13T01:02:27 < ds2> what's big? 10ft in dia?
2015-08-13T01:03:01 < BrainDamage> old xilinx ise is also dead now
2015-08-13T01:03:01 < BrainDamage> now there's some javashit
2015-08-13T01:03:14 < emeb> it's been years since I put it up there - it's probably bigger than 10'
2015-08-13T01:03:22 < BrainDamage> ( still prefer the old tool by a long shot )
2015-08-13T01:03:29 < BrainDamage> and i have the full license
2015-08-13T01:03:41 < emeb> BrainDamage: yes ISE is no longer supported. 14.7 was the last one and now they only push Vivado.
2015-08-13T01:03:53 < emeb> but Vivado doesn't have support for most of their parts.
2015-08-13T01:04:22 < emeb> as in you can't do any Spartan or Virtex designs with Vivado.
2015-08-13T01:04:31 < emeb> Only Zynq, Kintex, Artix, etc.

2015-08-13T05:09:10 < mtbg> it probably can

2015-08-13T07:33:56 < dongs> that was fast
2015-08-13T07:34:02 < dongs> did whiteman fix all the chiqn problems
2015-08-13T07:34:17 < dongs> when japs hired me in ~2001 that was my purpose there
2015-08-13T07:34:21 < dongs> to unfuck all teh shit they've ben fucking up
2015-08-13T07:35:57 < upgrdman> unfucked about 80% of it. will now complete unfucking it, and shifting some of the interrupt based stuff into dma based
2015-08-13T07:36:38 < upgrdman> annoying part was i didnt really need to be in china.
2015-08-13T07:36:43 < dongs> indeed
2015-08-13T07:36:48 < dongs> but free trip who cares
2015-08-13T07:36:51 < upgrdman> boss wanted me there so i could partake in the meetings, etc.
2015-08-13T07:37:05 < upgrdman> and get a real feel for the system and plans
2015-08-13T07:37:16 < upgrdman> but a fucking powerpoint + a phone call could have done that
2015-08-13T07:37:32 < upgrdman> ya, free trip was kinda neat.
2015-08-13T07:37:49 < upgrdman> also makes me realize all the first-world things i never noticed before
2015-08-13T07:38:12 < upgrdman> even simple shit, but using the same color temp light bulbs in a room... the chinese don't do right.
2015-08-13T07:38:26 < upgrdman> s/but/like

2015-08-13T07:40:51 < talsit> dongs: come to osaka uni, every other light is a different colour temp
2015-08-13T07:41:11 < dongs> do they even led there
2015-08-13T07:41:19 < upgrdman> dongs, dont go to china in the summer. well, hmm... if japan has same climate then maybe you wont care. but fucking HATED the hot AND humit weather
2015-08-13T07:41:38 < talsit> in my lab, yes, in the corridors, nope
2015-08-13T07:41:42 < aandrew> yeah HK they said do not come in like may
2015-08-13T07:41:51 < aandrew> I was there in january which was beautiful
2015-08-13T07:42:23 < dongs> upgrdman: yeah welcome to japan like 9 months of year like that
2015-08-13T07:42:33 < upgrdman> dongs, but seriously. so much of china lacks attention to details.
2015-08-13T07:42:40 < upgrdman> like starting off the day with a shower...
2015-08-13T07:42:47 < upgrdman> where the pressure and temp changes
2015-08-13T07:43:17 < dongs> i dont start hte day off wiht a shower either, but that might bec because i didnt sweat like a pig while sleeping. and took a shower before sleep
2015-08-13T07:43:25 < dongs> pretty sure japs dont do that either
2015-08-13T07:43:27 < upgrdman> and if you flush the toilet, the water pressure for the sink drops until the tank fills
2015-08-13T07:43:37 < dongs> haha, well, thats just shitty places
2015-08-13T07:43:51 < upgrdman> > shitty place
2015-08-13T07:43:55 < upgrdman> ^ most of .cn
2015-08-13T07:43:58 < dongs> ya

2015-08-13T07:47:44 < upgrdman> my hotel had western toilet
2015-08-13T07:47:58 < upgrdman> so did work, but the bathrooms at work were fucking disgusting
2015-08-13T07:48:15 < upgrdman> smelled and looked like public restrooms / bar restrooms
2015-08-13T07:48:20 < ds2> was shit outside of the bowl?
2015-08-13T07:48:24 < upgrdman> no
2015-08-13T07:51:42 < upgrdman> one of the things that made the trip worthwhile was seeing the owner of the company, and a few coworkers, doing karaoke.
2015-08-13T07:51:58 < upgrdman> is that an asian thing? absofuckinglutely loving karaoke?
2015-08-13T07:53:48 < dongs> probly

2015-08-13T15:36:57 < Laurenceb> resistors
2015-08-13T15:37:56 < zyp> yeah, I'm trying out other values now to make the green leds less awfully bright
2015-08-13T15:40:43 < Fleck> :D
2015-08-13T15:40:51 < Fleck> 470+ then maybe
2015-08-13T15:41:26 < Fleck> depends on Vin ofc
2015-08-13T15:41:30 < zyp> 3.3V
2015-08-13T15:41:45 < Fleck> and Vforward drop for led?
2015-08-13T15:42:10 < zyp> idk
2015-08-13T15:42:21 < Fleck> then 1k pot? :D
2015-08-13T15:42:58 < Laurenceb> i use 1k for LEDs
2015-08-13T15:43:42 < zyp> hmm, 330 still looks awfully bright
2015-08-13T15:45:46 < zyp> don't think I have any
2015-08-13T15:46:06 < zyp> I don't have anything larger in the range either, so I'll just try two 330 in series

2015-08-13T16:04:53 < zyp> haha
2015-08-13T16:05:02 < zyp> I think it's the same kind here
2015-08-13T16:06:33 < kakimir> what you think about including header files to project when content of those files are purelly informative?
2015-08-13T16:06:55 < rewolff> The leds take, about 2.17V  at 60 microamps. Do the math for 3.3V...

2015-08-13T16:19:00 < rewolff> But 4 "dupont wires" from the raspberry pi, or any arduino will do as well.

2015-08-13T19:12:04 < kakimir> so if I use inline in declaration function acts like static function but doesn't certainly mean that so you should use static too to make it actually static but if you want it to act extern like other functions by default you need to leave inline out of declaration or use extern with it :/
2015-08-13T19:12:40 < zyp> uh, what?
2015-08-13T19:12:55 < Fleck> feel ashamed :D as I did know I had to clear SECF, somehow could not put that info together in my head... heh
2015-08-13T19:13:10 < kakimir> http://www.greenend.org.uk/rjk/tech/inline.html is it tru
2015-08-13T19:13:33 < zyp> kakimir, what are you trying to do?
2015-08-13T19:15:08 < kakimir> inline function that is externally available
2015-08-13T19:15:24 < kakimir> leave inline out of declaration?
2015-08-13T19:16:39 < zyp> why do you want to mark it inline?
2015-08-13T19:17:13 < zyp> an optimizing compiler can choose to inline any function, marking a function with inline doesn't force it to always be inlined
2015-08-13T19:17:20 < zyp> so it's sort of a moot point
2015-08-13T19:17:46 < kakimir> so should not use inline at all?
2015-08-13T19:18:02 < zyp> why do you want to mark it inline?
2015-08-13T19:18:22 < Fleck> zyp: do you have git or smthn with code examples for stm32 peripherals?
2015-08-13T19:18:45 < zyp> Fleck, examples for what?
2015-08-13T19:18:55 < kakimir> if it's oneliner?

2015-08-13T19:20:21 < zyp> I mean, I have examples for my own library, but you probably don't want to do that, or?
2015-08-13T19:20:39 < Fleck> lib you mean - HAL CUBE?
2015-08-13T19:20:53 < zyp> yeah, or libopencm3 or whatever
2015-08-13T19:20:59 < zyp> there's a bunch of choices
2015-08-13T19:21:53 < Fleck> I have only looked at HAL CUBE, and I hate it, no normal docs etc, you read RM and kinda understand how stuff works, then you need to re-learn how to do the same with HAL CUBE :D
2015-08-13T19:22:59 < zyp> well, I don't have any example code for that.
2015-08-13T19:27:01 < kakimir> if many source files have functions by the same name. only another of header is being included. is there a problem?
2015-08-13T19:27:31 < kakimir> if I want to switch between impementations that have identical function naming
2015-08-13T19:27:37 < kakimir> bad idea?
2015-08-13T19:28:19 < kakimir> *only one of header
2015-08-13T19:32:11 < kakimir> leave other sets of sources out of makefile I guess is safe thing to do

2015-08-13T21:33:19 < Tectu> wtf
2015-08-13T21:33:25 < Tectu> embedded SRAM is pretty sure just the RAM
2015-08-13T21:33:27 < Tectu> FLASH is the flash
2015-08-13T21:33:30 < Tectu> but wtf is the system memory?
2015-08-13T21:34:09 < Tectu> anyway, I want flash memory, afaik
2015-08-13T21:36:21 < PaulFertser> Tectu: system memory is the bootloader rom.

2015-08-13T21:53:09 < Guest77211> Tectu: it's stm32 ( stm32f103cb)
2015-08-13T21:53:15 < Tectu> PaulFertser, and why would I boot from SRAM? Only for debugging/development purposes I assume?
2015-08-13T21:53:20 < Tectu> hey Fleck! How are you doing?
2015-08-13T21:53:32 < Fleck> good, thanks, you?

2015-08-13T22:06:54 < Tectu> PaulFertser, I had some serious issues with it
2015-08-13T22:07:01 < PaulFertser> Tectu: yes, SRAM boot is for debugging, when you want something that fits SRAM and it's faster to load than flashing.
2015-08-13T22:07:14 < Tectu> like ln -2 took 2 min to execute and then it stopped in the middle and only half of the stuff was reachable through the link
2015-08-13T22:07:17 < Tectu> ln -s
2015-08-13T22:07:24 < PaulFertser> Tectu: hm, strange, it's the official windows env for many projects. Probably conflicts with some tools from your generic PATH?
2015-08-13T22:07:38 < Tectu> PaulFertser, hmm, no idea
2015-08-13T22:07:42 < Tectu> PaulFertser, I also use cygwin a lot
2015-08-13T22:07:48 < Tectu> PaulFertser, but that was a fresh windows install
2015-08-13T22:07:52 < Tectu> PaulFertser, win10, probably because of that?
2015-08-13T22:08:00 < PaulFertser> msys2 is I think a cygwin done right.
2015-08-13T22:08:33 < Tectu> yes, I want to use msys2. just because it uses pacman
2015-08-13T22:08:43 < Tectu> but when I can´t use a simple ln -s it is a nogo for me
2015-08-13T22:09:20 < Tectu> hmm, I am downloading it, next try ;)
2015-08-13T22:13:24 < Tectu> PaulFertser, things like msys2 and cygwin are completely removed from the system when you remove their root directory, right?
2015-08-13T22:13:39 < Tectu> PaulFertser, they don´t put files anywhere else?
2015-08-13T22:23:24 < PaulFertser> Tectu: afaik, yes.

2015-08-13T23:14:39 < mtbg> and well, where does the people which try to think of emdrive theory of operation take into accont forces exerted on the walls of the waveguide which is not orthogonal to the direction of propagation?
2015-08-13T23:14:52 < mtbg> there is an angle which either has to be taken into account
2015-08-13T23:14:58 < mtbg> or proven it can be ignored
2015-08-13T23:16:41 < mtbg> ignoring these forces can be just like trying to ignore forces exerted by a liquid in conical container
2015-08-13T23:16:52 < mtbg> in gravity
2015-08-13T23:17:16 < mtbg> the force which a liquid in conical contrainer exerts on the bottom of the container is 3x its weight

2015-08-13T23:30:44 < mitrax> i had to mess with eagle yesterday... the guy who designed the UI deserves to die
2015-08-13T23:31:29 < mtbg> well, if you will build one, then I suggest to have a way to dissipate the same amount of power in the places in which the dissipation will occur due to microwave absoption or RF source heating
2015-08-13T23:31:38 < mtbg> but without using microwaves
2015-08-13T23:31:54 < mtbg> and with a way to switch between the two heating sources without touching the device
2015-08-13T23:33:08 < mtbg> I would suggest building a lock in amplifier also, but it can be tricky, as this equipment will have an inherent phase shift due to mass inertia
2015-08-13T23:33:36 < mtbg> which may be difficult to discriminate over thermal inertia

2015-08-14T03:28:03 < dongs> no need to explain
2015-08-14T03:28:52 < zyp> dongs, did you read what I mentioned about led lights?
2015-08-14T03:29:01 < dongs> did you prefix it wiht dongs:
2015-08-14T03:29:08 < zyp> I mean, resistors for those superbright leds
2015-08-14T03:29:09 < dongs> or was this few days ago
2015-08-14T03:29:10 < dongs> righgt
2015-08-14T03:29:17 < dongs> i thin i have 330R or 510R
2015-08-14T03:29:24 < dongs> 510 fo rsure, which one would you like?
2015-08-14T03:29:27 < zyp> http://bin.jvnv.net/f/3QJ4w.JPG <- I did some research
2015-08-14T03:29:38 < dongs> lole
2015-08-14T03:29:50 < dongs> ahh looks like i used 360R
2015-08-14T03:29:55 < dongs> had that on reel too
2015-08-14T03:30:04 < zyp> it's still bright at 990, but not too bad, so I guess if you have something in 1k-1.5k range it'll be good
2015-08-14T03:30:10 < dongs> i got 1k
2015-08-14T03:30:34 < zyp> ok, then you can use that for the two green ones, and leave the other two at 360
2015-08-14T03:30:56 < zyp> green ones should be R6/R7

2015-08-14T04:33:39 < dongs> theres some shots of interior assemly in this one tho
2015-08-14T04:35:22 < emeb> my understanding is that when they started using composites for so much of the aircraft that they had to ship huge components from all over to the final assembly site.
2015-08-14T04:35:24 < dongs> this must be some boeing PR thing, they deliver the timelapse together wiht plane
2015-08-14T04:35:46 < dongs> emeb: why? whats the difference
2015-08-14T04:35:56 < emeb> used to be that the metal parts were a lot smaller and were rivited together
2015-08-14T04:36:00 < dongs> you mean beacuse its like a single huge fuselage/etc thing?
2015-08-14T04:36:02 < dongs> ah
2015-08-14T04:36:35 < emeb> now they build them in one piece in huge autoclaves.
2015-08-14T04:37:39 < kakimir> monocock
2015-08-14T04:37:41 < emeb> seems like if the located the composite mfg near the final assy site they could save some hassle, but that's a multinational megacorp thinking for you.
2015-08-14T04:38:22 < kakimir> they propably wouldn't even
2015-08-14T04:38:32 < dongs> apparently they make wings for 787 in japan
2015-08-14T04:38:58 < kakimir> set up a rig for building such wing
2015-08-14T04:39:19 < kakimir> it's quite an investment
2015-08-14T04:41:03 < kakimir> I think it's more economical to have those factories doing different assembies little bit apart
2015-08-14T04:41:35 < kakimir> not to compete with itself in the area
2015-08-14T04:41:52 < kakimir> of resources
2015-08-14T04:43:40 < dongs> the only thing boeing makes is the vertical tail
2015-08-14T04:43:42 < dongs> nice

2015-08-14T08:52:26 < emeb_mac> just design a PCB and get over yourself dude.
2015-08-14T08:52:37 < mtbg> impressive
2015-08-14T08:52:47 < upgrdman> emeb_mac, note mine
2015-08-14T08:53:04 < upgrdman> emeb_mac, these days i would just have a pcb fab'd in 95% of the cases.
2015-08-14T08:53:15 < mtbg> even more than that bga pitch matching
2015-08-14T08:53:21 < upgrdman> i no longer have the free time to finish a project over a weekend like i used to
2015-08-14T08:53:34 < emeb_mac> upgrdman: ya - I know it's not yours - seen that pic elsewhere.
2015-08-14T08:53:43 < upgrdman> k
2015-08-14T08:53:46 < emeb_mac> but whoever did that is just jackin' off.
2015-08-14T08:53:51 < upgrdman> mmhmmm
2015-08-14T08:54:34 < emeb_mac> would have taken less time to do a proper PCB than to hand-solder that shit.
2015-08-14T08:54:48 < emeb_mac> and signal integrity would be better.

2015-08-14T13:23:21 < karlp> need to find a shop with cherry brown keyboards to see if they're really worth it
2015-08-14T13:23:38 < upgrdman> if i get one, it's be cherry blues. i like my clicky
2015-08-14T13:24:26 < karlp> oh hell noes, I have a keyboard now that's "fine" but its loud.
2015-08-14T13:24:35 < karlp> wakes the family up / keeps them awake.
2015-08-14T13:24:46 < karlp> I want a nice feeling keyboard that's quiet.
2015-08-14T13:24:49 < upgrdman> feature, not a bug :)
2015-08-14T13:24:58 < karlp> yeah, I know some people like it like that.
2015-08-14T13:25:24 < upgrdman> if i get one, it's coming with me to work so i can thoroughly piss off my coworkers
2015-08-14T13:25:53 < karlp> why just get a ps2 model m then?

2015-08-14T13:29:53 < karlp> 15gig _inside_ the vm
2015-08-14T13:33:05 < zyp> how much ram did you give the vm?
2015-08-14T13:33:31 < zyp> windows likes reserving a ton of space for a page file, so it can hold the entire ram content when you hibernate
2015-08-14T13:34:56 < karlp> ok, yeah, pagefile removal helped,
2015-08-14T13:35:12 < karlp> there's no hiberante though, powercfg -h off says that it doesn't support hibernate
2015-08-14T13:35:21 < Roklobsta> do the usual disk cleanup along with system files to remove stale windows updates dreck.
2015-08-14T13:35:44 < karlp> still using 10gig, Roklobsta: yeah, already run the disck cleanup thing to get rid of the updates as much as it can.
2015-08-14T13:35:55 < zyp> I seem to recall a fairly fresh windows install consuming almost 50GB here
2015-08-14T13:36:14 < zyp> the computer had 32GB RAM…
2015-08-14T13:36:58 < karlp> well, 10 gig is better than 15gig, I guess I'll just have to suck it up
2015-08-14T13:37:21 < dongs> karlp: wat?
2015-08-14T13:37:35 < dongs> < karlp> 15gig _inside_ the vm
2015-08-14T13:37:37 < dongs> o
2015-08-14T13:37:39 < dongs> yea, pagefile
2015-08-14T13:37:56 < karlp> yeah, pagefile got me down to 10gig, which still feels insane, but so be it.
2015-08-14T13:38:58 < dongs> karlp: there's a win7thinpc thing
2015-08-14T13:39:31 < karlp> I don't imagine I'm going to have any easy way of installing or licensing that
2015-08-14T13:39:56 < karlp> I don't even remember the key for this one, but it's a legit activated win 7, I can't do too much with it I guess.
2015-08-14T13:40:26 < dongs> its currently using 8gigs with swap off but I have circuitdonger installed in it
2015-08-14T13:40:33 < dongs> which is 1gb

2015-08-14T15:51:05 < Tectu> jpa-, but when I replace line 3294 with   x += 2*font->baseline_x;   then it works and the font is shifted to the right (by twice the amount specified in the font struct)

2015-08-14T16:24:42 < jpa-> Tectu: let's see
2015-08-14T16:27:22 < Tectu> jpa-, thanks for taking a look
2015-08-14T16:27:29 < jpa-> so what are you trying to achieve?
2015-08-14T16:28:33 < jpa-> mcufont internally subtracts baseline_x value from the x coordinate when rendering
2015-08-14T16:29:03 < jpa-> you say "I set the baseline_x of a font to 2"  does that mean modifying it from the value given by generator?
2015-08-14T16:30:00 < Tectu> jpa-, exaclty. Andrew once created the UI1 and UI2 font. The baseline_x parameters of those are 0 so they are always glued to the border which looks silly. I wanted to give it one or two pixel space
2015-08-14T16:30:18 < jpa-> ah, but the larger you make baseline_x, the more to the edge it goes
2015-08-14T16:30:48 < Tectu> jpa-, uh? UI1 and UI2 have 0 and they are on the edge. DejaVuSans16 has 1 and it is one pixel to the right and not at the edge (as I expected)
2015-08-14T16:31:10 < Tectu> jpa-, I only tried with the gdispGFillStringBox() function. just to be clear.
2015-08-14T16:31:10 < jpa-> if you mod dejavusans16 to have 0, it will be 2 pixels from edge i would think
2015-08-14T16:31:22 < Tectu> jpa-, let me try
2015-08-14T16:32:11 < jpa-> generally mcufont will render from edge-to-edge on the box coordinates you give it - but if the font designer has decided to leave a small gap in his fonts, mcufont will obey it
2015-08-14T16:33:04 < Tectu> jpa-, but that gap is baseline_x, no?
2015-08-14T16:33:08 < jpa-> nope
2015-08-14T16:33:11 < PaulFertser> You know when semihosting is really cool? When you lack SWO and debugging UART. And your target goes to the deepest sleep, wakes up with external reset from it, prints something over semihosting and sleeps again. Then you can know what's really happening, what's in RTC backup registers and how they get invalidated etc.
2015-08-14T16:33:24 < Tectu> jpa-, so when I want a bit of padding between the left edge of the box and the left-most pixel of the string I would increase basline_x, no?
2015-08-14T16:33:31 < jpa-> Tectu: baseline_x is so that characters can go beyond the left edge of a single character space
2015-08-14T16:33:41 < Tectu> jpa-, oh
2015-08-14T16:34:05 < jpa-> you would have to make baseline_x negative, but it is unsigned so won't work
2015-08-14T16:34:20 < Tectu> jpa-, so DejavuSans16 is not glued to the edge because the designer did leave a padding inside the actual glyph?
2015-08-14T16:34:39 < jpa-> yes, i would think so
2015-08-14T16:34:46 < Tectu> jpa-, so to give the UI fonts padding we would need to redesign the font or add a function that takes a padding parameter?
2015-08-14T16:34:54 < jpa-> if the fonts you want to modify are bwfont, you can increase offset_x there
2015-08-14T16:34:57 < Laurenceb> lol fontfags
2015-08-14T16:35:07 < Tectu> jpa-, no idea how andrew designed them.
2015-08-14T16:35:15 < Tectu> jpa-, let me check the dev-repo
2015-08-14T16:35:27 < jpa-> but if they are compiled as rlefont, then it is more difficult to modify
2015-08-14T16:35:52 < Tectu> jpa-, I have some .fon, .sfd and .bdf   here
2015-08-14T16:36:03 < jpa-> Tectu: nah i mean the mcufont font file

2015-08-14T16:36:15 < jpa-> is it mf_bwfont or mf_rlefont?
2015-08-14T16:36:34 < Tectu> do I tell fromt he struct type?
2015-08-14T16:36:43 < Tectu> mf_rlefont_s
2015-08-14T16:36:58 < jpa-> yeah, not that easy to modify then
2015-08-14T16:37:33 < Tectu> jpa-, but we could modify the font that andrew designed and re-compile?
2015-08-14T16:37:52 < jpa-> should work yeah
2015-08-14T16:38:04 < Tectu> well, time to wake up andrew :)
2015-08-14T16:38:40 < Tectu> jpa-, thank you for your help
2015-08-14T16:39:10 < Tectu> jpa-, I am currrently designin a textedit widget. quite a lot of magic happening that I did not expect (eg. cursor position calculation etc)
2015-08-14T16:39:32 < jpa-> yeah, and you will probably want to add some margin in the textedit itself
2015-08-14T16:40:18 < Tectu> jpa-, indeed. That is why I wanted to create a new function called gdispGFillStringBoxPadding() which is the same as gdispGFIllStringBox() but add the specified padding to the mcufont render call
2015-08-14T16:41:12 -!- Activate_for_moa [~A@213.87.133.174] has quit [Ping timeout: 264 seconds]
2015-08-14T16:42:01 < Tectu> jpa-, I am using gdispGetStringWidth() to calculate the pixel position of the cursor. The call itself is just a wrapper to some mcufont API. but I am not sure how to handle the character-internal padding or what ever
2015-08-14T16:42:09 < Tectu> or whether I should even care
2015-08-14T16:42:13 < jpa-> might also just make   padMyBox(&x, &y, &cx, &cy, padding);
2015-08-14T16:42:30 < jpa-> having a bazillion functions may not be the right way

2015-08-14T16:43:15 < Tectu> jpa-, how would that help? gdispGFillStringBox() will fill the entire box first. If I do something like that it will make the background box become smaller too
2015-08-14T16:43:26 < jpa-> ah, indeed
2015-08-14T16:45:10 < Tectu> jpa-, I could manually draw the box and then just the text but then we cannot use font anti-aliasing. If we cannot read back from the frame buffer we can still provide anti-aliasing when we know the background color.
2015-08-14T16:46:56 < jpa-> yeah, in nuttx there is a very annoying-to-write piece of code that fills just the borders around a text
2015-08-14T16:47:13 < jpa-> because i made a no-flicker optimization there so that it doesn't redraw the whole background
2015-08-14T16:47:39 < Tectu> jpa-, when doing a textedit widget which has a cursor, would you put the cursor to the left side of a character (so cursorPos = 0 means that it is on the left side of the first character) and allow the cursorPos to be bigger than the actual strlen() of the text so it can be on the right side of the last character? or how would you handle that?
2015-08-14T16:48:17 < Tectu> jpa-, well, we can do the same. We have the fontmetrics available. With existing API we can draw the background and then the text with background on top of that using the fontHeight and stringWidth functions.
2015-08-14T16:48:24 < jpa-> cursorPos is the index of the next character that will be written
2015-08-14T16:48:30 < Tectu> (and then use those metrics on gdispGFillStringBox()
2015-08-14T16:48:44 < jpa-> cursorPos=0 is on the left side of the first character, cursorPos = strlen(s) is on the right side of the last character
2015-08-14T16:48:57 < Tectu> okay, so I am doing it right and just suck at describing it
2015-08-14T16:49:05 < jpa-> you press a key and it does   s[cursorPos++] = readkeyboard();

2015-08-14T16:50:50 < Tectu> never mind, need to optimize this
2015-08-14T16:51:13 < Tectu> jpa-, would you do all of that with a buffer of a static size?
2015-08-14T16:51:17 < Tectu> which will always be too big?
2015-08-14T16:52:26 < jpa-> is your widget system without dynamic allocs?
2015-08-14T16:53:04 < Tectu> it is both
2015-08-14T16:53:17 < Tectu> you cann tell it to either go full static of dynamic
2015-08-14T16:53:40 < jpa-> i would say in static case, user provides buffer; in dynamic case, you can probably allocate it in widget
2015-08-14T16:53:45 < Tectu> gwinSetText() takes a parameter that specified whether it should copy it to an internal dynamic memory buffer or whether the supplied buffer is static
2015-08-14T16:54:08 < Tectu> jpa-, well, right now I re-allocate each time the text changes: http://paste.ugfx.org/show/fec4260cb6
2015-08-14T16:54:25 < Tectu> jpa-, note that gwinSetText() internally free()´s the previous buffer if it was allocated.
2015-08-14T16:55:20 < jpa-> don't do that, unless you like n^2 algorithms and memory fragmentation
2015-08-14T16:55:36 < Tectu> jpa-, I am trying to figure out how to do it right
2015-08-14T16:55:41 < jpa-> i would say just    createFancyTextWidget(size_t maximumSize);   would be good enough for embedded
2015-08-14T16:56:02 < jpa-> extra benefits: it will not fail randomly, if you don't have enough ram it will fail predictably
2015-08-14T16:56:25 < Tectu> hmm
2015-08-14T16:56:28 < Tectu> makes sense

2015-08-14T16:57:16 < jpa-> when i wrote that i got the + and - and x and y wrong way around like 1000 times

2015-08-14T17:47:57 < Tectu> are you working for
2015-08-14T17:48:00 < Tectu> pick which ever is correct
2015-08-14T17:48:02 < Laurenceb> line 163, what could possibly go wrong there...
2015-08-14T17:48:04 < Tectu> and tell me which oneis
2015-08-14T17:48:41 < upgrdman> i work for a medical xray company. parent company makes xray tubes. im working on some code for the parent company.
2015-08-14T17:49:01 < Tectu> so xray tubes need code these days? IoT is a bitch
2015-08-14T17:49:11 < upgrdman> their control boards do
2015-08-14T17:49:26 < upgrdman> it's not like an LED you just feed a constantish current to
2015-08-14T17:49:46 < upgrdman> also the control board often control/interact with other parts of the system
2015-08-14T17:49:49 < Laurenceb> over 9000 volts
2015-08-14T17:50:07 < upgrdman> xray detector, stepper motors, dc motors, ac motors, sensors, etc.
2015-08-14T17:50:25 < BrainDamage> that moment when you accidentally overdose a patient from a firmware bug
2015-08-14T17:50:28 < upgrdman> 50 - 400kV is common at my work
2015-08-14T17:50:48 < BrainDamage> do you only make emitters, or detectors too?
2015-08-14T17:51:02 < upgrdman> emitters
2015-08-14T17:51:21 < upgrdman> and support board for controlling the whole device
2015-08-14T17:51:23 < upgrdman> e.g.
2015-08-14T17:51:41 < upgrdman> xray food scanners, baggage scanners, shipping container scanners ....
2015-08-14T17:52:13 < upgrdman> so like you need to control the motors that operator the conveyor, etc.
2015-08-14T17:52:57 < upgrdman> some machines have multiple xray generators and detectors

2015-08-14T19:24:13 < jpa-> memset() would give some extra performance, but yeah seems reasonable
2015-08-14T19:24:17 < jpa-> err
2015-08-14T19:24:19 < jpa-> memcpy()
2015-08-14T19:24:50 < jpa-> but c strings are a performance hell anyway so i guess it is not worth optimizing much
2015-08-14T19:26:36 < Tectu> jpa-, ah, memcpy() instead of manual shifting?
2015-08-14T19:26:51 < jpa-> yeah, memcpy instead of for loop
2015-08-14T19:26:54 < Tectu> jpa-, shouldn´t one use strncpy() instead?
2015-08-14T19:27:08 < Tectu> as it would take care of the ´\0´ automatically
2015-08-14T19:27:17 < jpa-> that's one way also, but if you already know the length doesn't matter much
2015-08-14T19:27:40 < Tectu> Hmm, no idea why I wrote that loop instead of the cpy crap. time to try

2015-08-15T05:17:44 < dongs> yeah, its not for security
2015-08-15T05:17:46 < dongs> its as ReadError said
2015-08-15T05:17:46 < PeterM> why do you ask?

2015-08-15T05:38:16 < dongs> nuuh, fuck wifi
2015-08-15T05:38:24 < dongs> i wanna proper dvr that loops stuff on hdd
2015-08-15T05:38:26 < dongs> in h264 or whatever
2015-08-15T05:38:33 < dongs> i see abunch of shit for liek <$300 i just cant believe its that cheap
2015-08-15T05:38:38 < dongs> thats including cams
2015-08-15T05:39:29 < icee> so yah, the two approaches are analog cams + one of those cheap DVRs
2015-08-15T05:39:38 < icee> and they work OK
2015-08-15T05:39:46 < icee> and if you want to swap out a couple cams for nicer cams etc you can
2015-08-15T05:39:50 < dongs> there's 720/1080p hd stuff for same price
2015-08-15T05:40:01 < dongs> but there's liek 3-4 different techs
2015-08-15T05:40:09 < dongs> hd-sdi, and like 3 different "analog hd" shits
2015-08-15T05:40:40 < icee> yah, a lot of that stuff is not really HD, just increased horizontal resolution
2015-08-15T05:40:58 < icee> or the other way is network cameras + NAS
2015-08-15T05:41:20 < icee> like the synology NAS boxes will do smart stuff.. and a lot fo the cameras have decent in-camera motion detection and masking now
2015-08-15T05:50:22 < Sync_> dongs: is that analog hd shits actually in use in 2015?

2015-08-15T07:07:20 < emeb_mac> sometimes it will asplode!
2015-08-15T07:08:01 < emeb_mac> but they always suffer damage & need to be replaced.
2015-08-15T07:09:08 < dongs> yea sure
2015-08-15T07:09:09 < dongs> but i mean
2015-08-15T07:09:12 < dongs> does it short
2015-08-15T07:10:58 < emeb_mac> not certain. I think they fail open - generally one they blow up they're out of the circuit.

2015-08-15T07:21:16 < dongs> it does short
2015-08-15T07:21:20 < dongs> rotated it around and board works
2015-08-15T07:21:27 < dongs> continuing to pro the fuck around
2015-08-15T07:25:18 < emeb_mac> blowing up tantalum caps is super-pro
2015-08-15T07:35:04 < PeterM> iirc the reverse breakdown voltage on tants is pretty low, so yeah, it'll short and without current liminting it will literally explode
2015-08-15T07:35:52 < PeterM> like it wont just pop like an electro, it will bang like shorting a lipo with a mosfet
2015-08-15T07:36:22 < emeb_mac> craters in the plastic packaging. impressive effects.
2015-08-15T07:36:55 < PeterM> usually my tants are more like "just end caps left on the board"

2015-08-15T11:46:13 < upgrdman_> damn it
2015-08-15T11:46:22 < upgrdman_> fucking ups batteries shit the bed
2015-08-15T11:46:39 < upgrdman_> used to get 3hrs out of them. just got maybe 15 minutes from them
2015-08-15T11:47:43 < PeterM> upgrdman_, they're probably constantly being trickle charged or something
2015-08-15T11:47:50 < upgrdman_> ya
2015-08-15T11:48:02 < upgrdman_> im not mad per se, just mad i have to buy new ones
2015-08-15T11:48:07 < PeterM> also, they in series for 48v or is it small ups?
2015-08-15T11:48:11 < upgrdman_> these are myabe 3-4yrs old, so it's about their time
2015-08-15T11:48:19 < upgrdman_> 2 in series. 24
2015-08-15T11:48:23 < upgrdman_> 24v total
2015-08-15T11:48:28 < upgrdman_> dual 12v 7ah
2015-08-15T11:48:38 < PeterM> oh, small ups
2015-08-15T11:48:40 < upgrdman_> ya
2015-08-15T11:49:00 < upgrdman_> was for my workstation, but these days it just powers modem/router/nas/rasPi
2015-08-15T11:49:16 < upgrdman_> so way overkill for a 25w load, but i have it laying around
2015-08-15T11:49:40 < PeterM> for modem/router/pi/nas i'd make DC ups, you probably burn more in hte dc-ac-dc than in the actual usage
2015-08-15T11:51:36 < upgrdman_> i guess i could be a bit less lazy and do that
2015-08-15T11:52:57 < upgrdman_> is the trivial way to feed the dc load from two diode'd sources (power brick and lm317) ?

2015-08-15T12:09:16 < PeterM> nah, dont even need to do that, just float charge the battery from a powersource capable of powering all the peripherals and run the dc-dc straight from the battery, until the load draws more than the current
2015-08-15T12:12:35 < upgrdman_> oh ya that makes sense
2015-08-15T12:13:14 < upgrdman_> any recommendation for a dcdc module with adjustable output?
2015-08-15T12:13:19 < upgrdman_> im mousering
2015-08-15T12:13:58 < upgrdman_> hmmm actually we might have a fuck ton of isolated dcdc modules at work
2015-08-15T12:14:23 < PeterM> i have a reel of chinatrash XL2010 that i use for this kinda thing

2015-08-15T16:59:32 < PaulFertser> upgrdman_: sometimes they write native words with the alphabet for other languages too for "fashion reasons". But the thing is that they really have two different alphabets (where each symbol stands for some simple sound combination, like most other written languages) and ~2k words from chinese (one complex symbol per "word"). dongs amirite?
2015-08-15T16:59:46 < dongs> yea
2015-08-15T17:00:01 < upgrdman_> k
2015-08-15T17:00:13 < PaulFertser> They used to have other alphabets too for reasons even more obscure.

2015-08-15T17:02:08 < upgrdman_> do the stole chinese words that the japs use have the same meaning? or do the chineses and japanese have different meanings for the symbols?

2015-08-15T17:03:08 < dongs> what chinks fail to realize is that english is the universal language

2015-08-15T17:08:58 < upgrdman_> will probably spend 2 - 3 months there per year
2015-08-15T17:09:42 < upgrdman_> because the chinese engineers my company has can't code for shit, and don't even know how to attempt system integration
2015-08-15T17:10:40 < Steffanx> so why even borther using chinese coders? :)
2015-08-15T17:10:43 < Steffanx> oh, because cheap
2015-08-15T17:11:06 < upgrdman_> and before i go back (probably sometime in 2016) i need to figure out how to get decent access to the internet while there. vpns work, but chinea backbones to the outside work are overloaded
2015-08-15T17:11:39 < upgrdman_> tempted to look into satellite net service
2015-08-15T17:12:19 < BrainDamage> prepare for latencies of 2-3s and outrageous costs
2015-08-15T17:12:40 < upgrdman_> theres latencies of like 5s while using the net in china
2015-08-15T17:12:51 < upgrdman_> if you try to access any server outside of .cn
2015-08-15T17:13:06 < upgrdman_> i may be able to expense report the cost, if i bitch enough
2015-08-15T17:13:23 < upgrdman_> so im more focused on "how the fuck can i solve this problem" right now
2015-08-15T17:13:37 < upgrdman_> even IRC was sketchy when over there
2015-08-15T17:14:06 < upgrdman_> they drop packets faster than they cast away girl babies

2015-08-15T17:17:11 < BrainDamage> iirc last time i looked, you'll be paying for 1.5-2k€ for the device and extra 1.5k€ for a year subscription
2015-08-15T17:19:32 < upgrdman_> i'd be happy with that, as long as it fucking worked
2015-08-15T17:20:43 < BrainDamage> iridium had less atrocious costs for both, but you'd be limited to less than a 56k modem
2015-08-15T17:21:30 < upgrdman_> ya i was getting 1 - 3 KBps at times, so even 4KBps would be a welcomed change
2015-08-15T17:21:46 < upgrdman_> biggest problem is dropped packets.
2015-08-15T17:21:53 < upgrdman_> china loves to drop

2015-08-15T17:25:29 < upgrdman_> and that's just for irc. super low bandwidth and latency requirements.
2015-08-15T17:25:40 < Laurenceb_> I'm convinced google loon is a "spoof" project
2015-08-15T17:25:54 < Laurenceb_> the all optical network just doesnt make sense
2015-08-15T17:26:53 < Steffanx> it makes more sense than zano ..
2015-08-15T17:27:44 < Laurenceb_> heh
2015-08-15T17:28:02 < Laurenceb_> theres a nice ISM band at 24Ghz they could use
2015-08-15T17:28:46 < Laurenceb_> nearly as directional as optical and no problem with crazy high noise temperature from the sky
2015-08-15T17:29:08 < upgrdman_> ah fuck. seem most of these sat providers require a 1.8m dish. so much for covert dish placement

2015-08-15T20:05:25 < PeterM> yeah, i use a lot of it, i often need to make wiring harnesses and such for equiptment, i like silicone indulated, finely stranded wire because it doesnt fatigue
2015-08-15T20:05:33 < PeterM> or atleast,m not as badly
2015-08-15T20:06:29 < ReadError> yea i use wire as weight filler

2015-08-15T20:08:06 < PeterM> they are prettydecent for heatshrink too, but i dont use them because it doesnt come on a reel, it coems as the scruinched up bundle - its competetively priced at HK but other places have it jsut as cheap too

2015-08-15T20:21:26 < PeterM> a 5000 4S is around 74Wh, a 7Ah 12v SLA is about 80Wh, but the lipo is smaller, lighter, has a better cycle life and can be cheaper

2015-08-16T02:10:26 < Laurenceb_>  anyone got any ideas on how to put an animation into a pdf?
2015-08-16T02:10:27 < Laurenceb_> without resorting to gif
2015-08-16T02:10:56 < zyp> wat
2015-08-16T02:11:00 < zyp> can you even do that?
2015-08-16T02:11:05 < Laurenceb_> yes
2015-08-16T02:11:10 < zyp> I've never seen any sort of animations in a pdf
2015-08-16T02:11:11 < Laurenceb_> but i can't :-/
2015-08-16T02:11:19 < Laurenceb_> apparently its doable
2015-08-16T02:11:32 < Laurenceb_> you can even embed video
2015-08-16T02:11:50 < Laurenceb_> theres an animate latex package but its failing for me
2015-08-16T02:12:02 < Laurenceb_> maybe i should go hardcore and embed a video file
2015-08-16T02:12:13 < zyp> sounds silly
2015-08-16T02:12:16 < gxti> i have never seen an animated pdf and i hope i never will
2015-08-16T02:12:20 < Laurenceb_> lol
2015-08-16T02:13:02 < Tectu> Laurenceb_, do you have an example of a pdf with animations?

2015-08-16T07:47:38 < PeterM> yeah
2015-08-16T07:48:40 < dongs> http://en.radzio.dxp.pl/bitmap_converter/
2015-08-16T07:48:40 < dongs> ooo
2015-08-16T07:50:13 < mtbg> if you want that human readable format, you can still have it, but will have to change the headers to flip bit order and then rotate that table and flip the column addressing with that adc command
2015-08-16T07:50:23 < mtbg> without flipping it still will be readable but mirrored
2015-08-16T07:50:24 < mtbg> :>
2015-08-16T07:50:56 < mtbg> or, change the loading function to flip while loading
2015-08-16T07:51:07 < dongs> yeah that converter worked
2015-08-16T07:51:11 < dongs> using "vertical" byte orientation
2015-08-16T07:51:23 < dongs> mtbg, i spent this morning making that transfer DMA
2015-08-16T07:51:29 < dongs> so it takes 560us to update entier screen
2015-08-16T07:51:36 < mtbg> oh ok
2015-08-16T07:51:36 < dongs> im not gonna change it to flip bytes around ;d
2015-08-16T07:51:38 < mtbg> nice
2015-08-16T07:51:52 < mtbg> is it connected to FSMC?

2015-08-16T07:53:23 < mtbg> the controller itself supports serial mode?
2015-08-16T07:53:44 < dongs> yeah, its one of those chinq shits that does parallel/spi/whatever

2015-08-16T07:58:18 < dongs> holy fuck all tarduino libs that do graphics on these just directly write pixel by pixel into displayram
2015-08-16T08:00:02 < PeterM> thats probably why they update at like 10hz
2015-08-16T08:00:03 < mtbg> probably so that they can have some graphic functions for drawing circles and whatnot
2015-08-16T08:00:43 < dongs> mtbg, er wat
2015-08-16T08:00:55 < dongs> i meant the part about "directly writing to displayram"
2015-08-16T08:02:20 < mtbg> yep, but to draw some shape from code on the display you would either have to buffer the whole thing in RAM and then update
2015-08-16T08:02:26 < mtbg> or draw pixelwise

2015-08-16T08:53:55 < dongs> neat but,
2015-08-16T08:53:58 < dongs> how do you control volume?
2015-08-16T08:54:03 < dongs> if it just interrupts the light
2015-08-16T08:54:46 < mtbg> I think it reflects the light, since there is no sensor on the opposite side of the beam
2015-08-16T08:54:51 < mtbg> it just hits the ceiling
2015-08-16T08:54:58 < dongs> you think?
2015-08-16T08:55:03 < mtbg> there must be some photodiode near the projector output
2015-08-16T08:55:18 < mtbg> and it detects reflection in synchronisation to the mirror rotation
2015-08-16T08:55:21 < mtbg> in the projector
2015-08-16T08:55:42 < dongs> i dont think that would work
2015-08-16T08:56:13 < dongs> how would you tell which beam youre hitting
2015-08-16T08:56:39 < mtbg> there is just one beam but scanning and turning on and off
2015-08-16T08:56:43 < mtbg> like in laser printer
2015-08-16T08:56:47 < dongs> right
2015-08-16T08:59:23 < mtbg> it can't detect the exact distance where the beam was crossed, but the good thing is that the number of "strings" is just limited by projecting space (angle) and by resolution of the detector in time

2015-08-16T09:02:00 < dongs> gonna find out
2015-08-16T09:02:30 < Roklobsta> you talking about a laser harp like JM Jarre's got?
2015-08-16T09:04:11 < mtbg> like this in that video

2015-08-16T09:06:29 < mtbg> white gloves to reflect light better, I guess
2015-08-16T09:07:09 < Roklobsta> looks like a lawn sprinkler i used to have
2015-08-16T09:07:56 < dongs> reflect to waht

2015-08-16T09:09:58 < Roklobsta> probably a beam splitter where the laser shoots out before it hits the mirror.  The reflected light comes back in, through the splitter and enough light should trigger a sensor.  It'd probably helpt to gate the sensor too so it doesn't pick up ambient light that might gen in via the same path.

2015-08-16T09:11:39 < mtbg> might be
2015-08-16T09:12:24 < mtbg> but still, the laser light is much brighter than it seems, it is just switched for a very short time
2015-08-16T09:12:49 < mtbg> so the detector will still get much stronger response to this than to ambient light
2015-08-16T09:12:56 < mtbg> given enough bandwidth
2015-08-16T09:16:36 < Roklobsta> a filter on the sensor would help too

2015-08-16T10:53:05 < upgrdman_> have you tried running it with vin <8V?

2015-08-16T14:19:18 < artag> did they actually blow $3.5m ? towards the end it says the investor syndicate couldn't agree terms, so have they actually 'only' spent the 0.5m kickstarter money ?

2015-08-16T14:19:56 < artag> well, not for you point, no. But I'm curious.
2015-08-16T14:20:10 < artag> how they could get through $3.5m without doing anything
2015-08-16T14:20:54 < dongs> zano is about to do that

2015-08-16T14:26:46 < artag> more on-topic .. I've been looking at both the ST libraries and the libopencm3 libraries for an stm32f3 project. The ST libraries look awful - too many definitions, overcomplicated, fiddly code. The libopencm3, just glancing at a few functions, seem far easier to understand because they have a sensible amount of comment, they're not drowning in doxygen and formatting.
2015-08-16T14:27:15 < artag> Is that reasonable or has the libopencm3 got loads of stuff missing ?
2015-08-16T14:27:18 < dongs> wait till you try cube
2015-08-16T14:27:52 < artag> is that worse ? I couldn't get it to run because it was so fussy about OS and java versions
2015-08-16T14:28:30 < artag> or will all my problems magically disappear ?
2015-08-16T14:34:43 < zyp> rumors has it that cube is worse
2015-08-16T14:36:10 < artag> shan't explore that rabbit-hole in a hurry, then.
2015-08-16T14:39:43 < zyp> dongs, did you see this: http://arstechnica.com/business/2015/08/most-funded-european-kickstarter-project-ever-still-hasnt-shipped-yet/ ?
2015-08-16T14:40:03 < zyp> you haven't linked to it here
2015-08-16T14:40:52 < dongs> i just tweeted it to someone else

2015-08-16T14:42:55 < zyp> heh
2015-08-16T14:44:15 < mtbg> and night and are delivering on our promises. Also remember that Zano hardware is future proofed so though the initial functionality will be limited, the sky is the limit and we will continue on a regular and frequent basis push out features once we have completely tested them and signed off.
2015-08-16T14:44:41 < zyp> maybe they are planning to waterproof it through a software upgrade
2015-08-16T14:44:56 < mtbg> I doubt if they can implement much features
2015-08-16T14:45:11 < mtbg> if that PIC will have to save full hd to SD card in real time

2015-08-16T14:46:47 < Steffanx> dongs does hobby bobby wifi?
2015-08-16T14:54:26 < jpa-> artag: well, if you want wrapper functions, libopencm3 sure is nicer.. but you can get pretty far with just the register definitions (stm32fxxx.h) from ST libraries

2015-08-16T16:06:59 < PeterM> dongs you going to call it uDONGS instead of uGFX?
2015-08-16T16:07:06 < dongs> yea

2015-08-16T16:07:55 < Tectu> oh no, competition
2015-08-16T16:07:57 < Steffanx> but does this use your mcufont stuff jpa-?
2015-08-16T16:08:04 < dongs> what is mcufont

2015-08-16T16:08:24 < dongs> has it been moved to shithub yet
2015-08-16T16:08:27 < dongs> i see it has been

2015-08-16T16:08:30 < Tectu> dongs, well, I guess I can delete the ugfx repo then and format the webservers HDD

2015-08-16T16:08:40 < dongs> holy shit
2015-08-16T16:08:54 < dongs> o cool, its also vector
2015-08-16T16:09:00 < jpa-> is not really vector
2015-08-16T16:09:12 < Tectu> jpa-, I see you did some committing
2015-08-16T16:09:13 < jpa-> just can import vector
2015-08-16T16:09:49 < jpa-> Tectu: yeah, added one function to compute cursor positions, then i again thought "wtf am i doing free work for closed sores stuff again" and stopped wondering about cursor positions
2015-08-16T16:10:17 < Tectu> jpa-, how about you continue? ugfx sores are 100% open
2015-08-16T16:10:25 < Tectu> also dual license coming up (most likely)
2015-08-16T16:10:50 < jpa-> doubt it, and it'll probably be dual license for 1 week and then someone changes their mind again
2015-08-16T16:12:12 < Steffanx> lol
2015-08-16T16:13:04 < dongs> lol
2015-08-16T16:13:07 < dongs> so yeah
2015-08-16T16:13:20 < dongs> fuck ugfx, i have like 90% of stuff I needed to do on that display done already
2015-08-16T16:13:35 < dongs> scalable vector fonts + draw bitmap + draw graph/pixels
2015-08-16T16:13:59 < Steffanx> but not in such quality
2015-08-16T16:14:14 < Steffanx> and it's closed sores
2015-08-16T16:14:20 < jpa-> instead, actually works?
2015-08-16T16:14:53 < jpa-> scalable non-antialiased non-hinted vector fonts.. hm, that is one way to do it
2015-08-16T16:15:07 < dongs> jpa, on a 128x64screen?
2015-08-16T16:15:12 < dongs> monochrome etc.
2015-08-16T16:15:19 < dongs> i dont think theres space for aliasing or hinting.
2015-08-16T16:15:50 < jpa-> yep

2015-08-16T21:19:29 < PaulFertser> Blok: malloc is compiled code, too late to do any preprocessor hacks :)
2015-08-16T21:23:34 < Blok> Not sure what you mean. I control all calls to malloc in the code I compile. Or, well, that is partially true because somewhere in between this lies the problem.
2015-08-16T21:30:22 < PaulFertser> Blok: so all calls to malloc you make are from your own functions? But what about printf, strftime and such?
2015-08-16T21:30:45 < PaulFertser> Substituting allocator like that is a bad idea usually.

2015-08-16T21:44:31 < Blok> PaulFertser: First, agree. Yes, all calls are from my functions, this is a realtime issue. My problem was a missed call to calloc. It now behaves as it should.
2015-08-16T21:45:20 < PaulFertser> Blok: do you use a debugger? You can place a breakpoint on _sbrk and then watch backtrace.
2015-08-16T21:45:28 < PaulFertser> That would show you the calling place promptly.

2015-08-17T11:40:40 < ReadError> I have a 10k:1k voltage divider with a 100nF cap to ground after
2015-08-17T11:41:15 < ReadError> it seems when the voltage before the divider gets noisey, the output drops quite a bit
2015-08-17T11:42:11 -!- mumptai [~calle@x4d0ad365.dyn.telefonica.de] has quit [Quit: Verlassend]
2015-08-17T11:43:05 < ReadError> could the capacitor be acting up with high freq noise and skewing out output?
2015-08-17T11:43:46 < Roklobsta> how are you detemining this noise?  observed signal in system or a cro?
2015-08-17T11:44:32 < ReadError> well im running a BLDC which sinks about 20A
2015-08-17T11:44:51 < ReadError> so the switching of fets off and on under a load probably is causing sink/spike
2015-08-17T11:45:36 < ReadError> i was thinking about adding an opamp with a unity gain configuration to see if that helps
2015-08-17T11:46:26 < jpa-> are you sure the input does not drop also?
2015-08-17T11:46:28 < mtbg> average voltage ratio should stay the same
2015-08-17T11:48:05 < ReadError> jpa- well for example, if I drop 0.1-2V on pre-divided, im showing a drop of almost 1.3V post divided
2015-08-17T11:48:07 < mtbg> RMS ratio may change
2015-08-17T11:49:15 < jpa-> ReadError: how are you measuring the pre-divided drop? how are you measuring the post-divider drop?
2015-08-17T11:49:35 < ReadError> post divided drop im using the STM ADC
2015-08-17T11:49:42 < ReadError> pre-divided I was using my fluke
2015-08-17T11:50:06 < ReadError> measuring current im getting really solid #s but im using an opamp to buffer
2015-08-17T11:50:13 < jpa-> try checking with fluke post-divider also
2015-08-17T11:53:33 < ReadError> yea would be worth a shot, it happens so quickly I wasnt sure if that would work
2015-08-17T11:54:28 < jpa-> microcontroller ADC's are also quite sensitive to noise on the Vref pin
2015-08-17T11:54:40 < jpa-> IIRC more sensitive than to the noise on the ADC input
2015-08-17T11:55:02 < ReadError> well vref is tied to vdd currently
2015-08-17T11:55:18 < ReadError> not using an external reference
2015-08-17T11:55:20 < jpa-> is vdd nice and clean?

2015-08-17T14:00:44 < ReadMobl> 1.419 @ STM pin = 15.609
2015-08-17T14:00:44 < ReadMobl> 1.458 @ Source = 16.038
2015-08-17T14:01:26 < ReadMobl> the only thing between the source and stm pin is a bit of jumper wire and its not really high current
2015-08-17T14:03:18 < mtbg> that is odd
2015-08-17T14:03:32 < ReadMobl> yea very
2015-08-17T14:04:54 < jpa-> were the measurements against the same gnd?

2015-08-17T14:23:46 < ReadMobl> maybe have the answer, the ESC backfeeds power over ground which shifts the avss
2015-08-17T14:25:33 < mtbg> then you routed it in a wrong way
2015-08-17T14:26:12 < jpa-> "duh"
2015-08-17T14:30:17 < ReadMobl> well I have about 8x 220uF capacitors before the power on the ESC which helps but since the signal/gnd were connected it would skip the capacitor bank on that part
2015-08-17T14:31:01 < mtbg> capacitor bank doesn't help with DC current
2015-08-17T14:31:41 < mtbg> only decouples AC
2015-08-17T14:32:57 < ReadMobl> well the power its feeding back is AC right? 'active freewheeling' on a brushless motor?
2015-08-17T14:33:22 < jpa-> ReadMobl: mind sharing your layout / screenshot of problematic path? i'll be designing a custom esc-thingy some time in near future and would like to avoid your mistakes ;)
2015-08-17T14:33:38 < ReadMobl> jpa-: i didnt design the ESC :)
2015-08-17T14:35:05 < ReadMobl> I have one i need to fix though ;/
2015-08-17T14:39:04 < ReadMobl> jpa-: the ESC isnt problematic, it was doing what it was supposed to do, just an oversight on how the active braking stuff would effect avss
2015-08-17T14:40:28 < jpa-> traces go somehow so that voltage drop on vss goes undivided?
2015-08-17T14:41:32 < PeterM> ReadMobl, need star grounding much?
2015-08-17T14:42:43 < jpa-> star grounding everything is rarely possible
2015-08-17T14:42:55 < jpa-> though a good groundplane rarely drops enough voltage to matter
2015-08-17T14:44:24 < ReadError> jpa- ive not actually done a PCB for this yet, it was mostly just an exercise to get familiar with chibios, its just a wiring clusterfsck atm
2015-08-17T14:51:33 < mtbg> so maybe you can connect the ground so that the high current doesn't pass through the same wires as the rest of gnd
2015-08-17T14:52:09 < ReadError> mtbg well I have common ground with the ESC still
2015-08-17T14:52:25 < ReadError> its just wired so it can only traverse the capacitors

2015-08-17T20:57:55 < dongs> loool
2015-08-17T20:57:58 < dongs> zano delayed again
2015-08-17T20:58:11 < dongs> With that being said, let's get down to business. In order to optimise efficiency of the manufacturing and testing process, we've created an automated test rig. This test rig is essential in calibrating all the sensors on board ZANO, testing the camera, motors and the general success of the build. The test rig is absolutely vital in the volume manufacturing process, ensuring every ZANO we ship is calibrated and functional.
2015-08-17T20:58:19 < dongs> We've encountered a number of unexpected minor software issues in our test rig which is affecting our ability to calibrate and test the ZANOs for volume manufacturing.
2015-08-17T20:58:22 < dongs> Obviously, without the test rig performing as expected, we cannot begin the fulfilment process. Rest assured, however, that we're working our tails off to make sure this is rectified in days, not weeks.
2015-08-17T21:04:41 < Tectu> got some pics that go with that?
2015-08-17T21:14:49 < dongs> Tectu: amazing pics of testrig are going to be in next update "soon"

2015-08-17T21:20:52 < dongs> We have created a bespoke web application from the ground up which will allow you to view, share and enhance the photos and videos your ZANO's produce. The new website update is the first part of the roll-out of this application. In the very near future the My Account section will become active and those who have registered a ZANO via they mobile APP will be able to log in and use the applications tools.
2015-08-17T21:20:59 < dongs> The web application forms part of, what will be, the broader ZANO experience - it takes a very broad range of skills to make it all happen. Please don't think that the release of a new website means that we are not focusing on the other key areas - we most definitely are. I can assure you the other teams within ZANO are working their socks off.

The MAX77826 contains a high-efficiency BUCK regulator, a BUCK BOOST regulator, and 15 LDOs to power up peripherals."     does anything really need 15 LDOs?
2015-08-17T23:55:32 < yan_> upgrdman: no, but 15 LDOs probably covers 95% of use cases

2015-08-18T01:02:01 < ColdKeyboard> How can I create uart.c so I can use uart_putch(UART1, 0x53) to send 'S' to UART1?
2015-08-18T01:02:29 < ColdKeyboard> I tried combination of *, & and etc but I'm not that good with C pointers and structs :\
2015-08-18T01:03:05 < ColdKeyboard> I have some code like this one http://pastebin.com/pfsnjih1 but It doesn't work... I'm messing something up :\
2015-08-18T01:04:06 < upgrdman> what is it failing on?

2015-08-18T01:10:42 < ColdKeyboard> I'm not sure what should be pointer, what should be address and what should be...whatever it should be :)
2015-08-18T01:12:17 < upgrdman> and im too lazy to look into it :)
2015-08-18T01:12:19 < upgrdman> but

2015-08-18T04:51:45 < dongs> Possibly ZANO has a low cost temperature sensor that requires calibration?
2015-08-18T04:51:45 < dongs> ZANO would need to know the current air temperature to compensate for the change in the speed of sound through air at different temperatures, thus generating a more accurate down facing sonar measurement. Knowing the air temperature could aid in greater accuracy in altitude changes using the on board barometric sensor. ZANOs accelerometers and gyros would need calibration parameters stored as well, to improve inertial navigation indoors.
2015-08-18T04:51:55 < dongs>  lole
2015-08-18T04:57:47 < dongs> ya?
2015-08-18T04:57:54 < dongs> you never seen a plunger?
2015-08-18T04:58:25 < Yoduza> $20 devboards ?
2015-08-18T05:00:56 < dongs> R2COM: they're not going to be doing temperature compensation on a 50gram toy
2015-08-18T05:01:00 < dongs> plus it would take literally hours
2015-08-18T05:01:01 < dongs> per unit
2015-08-18T05:01:09 < dongs> to heat it up in an oven and cool down
2015-08-18T05:01:12 < dongs> and log the biases
2015-08-18T05:05:33 < mtbg> well, if they have sensors on separate board, then they could calibrate dozens of these at one cycle
2015-08-18T05:05:39 < dongs> they dont
2015-08-18T05:11:35 < aandrew> all temperature sensors are low cost these days
2015-08-18T05:17:52 < dongs> every gyro sensor has one built in these days too
2015-08-18T05:17:54 < dongs> also pressure snsor
2015-08-18T05:18:16 < dongs> esp pressure, since you need temperature to compensate pressure measurement
2015-08-18T05:21:05 < dongs> real;ly

2015-08-18T05:30:48 < dongs> im just browsing their site
2015-08-18T05:30:59 < dongs> assburgering instead of working
2015-08-18T05:31:50 < dongs> they're kinda lying
2015-08-18T05:31:57 < dongs> what it really is is a tuner + demod in a single chip
2015-08-18T05:32:03 < dongs> none of this 'direct to bits' tarsh
2015-08-18T05:32:19 < dongs> wait no wat
2015-08-18T05:32:40 < dongs> they're doing some prefiltering then dumping the shit over I2S jsut because, but its still not audio stuff and needs to continue being decoded
2015-08-18T05:37:14 < icee> dongs: that's a pretty typical downconversion part

2015-08-18T05:38:08 < dongs> it sends digitized shit over I2S
2015-08-18T05:38:29 < dongs> a tuner would be outputting quadrature / low IF as analog.

2015-08-18T08:51:04 < dongs> they cant even decode jpeg stream from camera
2015-08-18T08:51:10 < dongs> they can only resend it via wifi to phone
2015-08-18T08:51:14 < dongs> in shitty rez
2015-08-18T08:51:21 < dongs> and *maybe* write to a newly formatted SD card

2015-08-18T12:53:58 < dongs> i shoulda just gogoled
2015-08-18T12:54:24 < dongs> oh. still doesnt mention the formulaa for it tho.
2015-08-18T12:54:44 < dongs> " If the application uses very large output capacitance or requires a specific soft-start time, it is better to select a converter with externally programmable soft-start; the soft-start time can be set by an external capacitor."
2015-08-18T12:54:48 < dongs> how does a nigga calculate this
2015-08-18T12:54:56 < PeterM> upgrdman, any non-sync boost converter can be run as a sepic, to get your buck-boost

2015-08-18T13:01:28 < PeterM> >2A is a bit hard at higher voltages though
2015-08-18T13:02:28 < PeterM> dongs its something like how long will cap take to charge to vout via the current form the SS pin or something, so example, how long it will take 1uF to charge to 12v with 5uA charge current will get your SS time
2015-08-18T13:02:42 < dongs> yreah where is the charge current tho
2015-08-18T13:03:06 < dongs> oh
2015-08-18T13:03:09 < dongs> fuck, its rigth there
2015-08-18T13:03:14 < dongs> The chip provides a 6mAcharge current
2015-08-18T13:03:14 < dongs> for the external capacitor. If 0.1mF capacitor is used to
2015-08-18T13:03:15 < dongs> set the soft-start, the period will be 13.5ms(typ.).
2015-08-18T13:03:41 < dongs> i think i read that
2015-08-18T13:03:42 < dongs> and skipped it
2015-08-18T13:03:46 < dongs> cuz they didnt have an actual formula
2015-08-18T13:03:53 < dongs> for my pro-irc-ee- brain to copypaste
2015-08-18T13:04:40 < PeterM> is it 6ma or 6 ua

2015-08-18T14:50:08 < dongs> pretty much
2015-08-18T14:50:11 < zyp> dongs, I got the credit memo yesterday, it explicitly states «DUE TO $ AMT CUST WILL NOT NEED TO RETURN PARTS.»
2015-08-18T14:50:18 < dongs> excellent
2015-08-18T14:50:25 < dongs> lets make a 24-core zano stack
2015-08-18T14:50:42 < zyp> we wouldn't need parts to never deliver
2015-08-18T14:51:00 < dongs> does that package have enough pins for SDRAM?
2015-08-18T14:51:01 < PeterM> lolled
2015-08-18T14:51:11 < ReadError> why is the variance so high that they need to calibrate each zano?
2015-08-18T14:51:19 < ReadError> I dont get it
2015-08-18T14:51:22 < dongs> ReadError: its not
2015-08-18T14:51:29 < dongs> they're just pulling excuses out of ass.
2015-08-18T14:51:32 < dongs> to stall.
2015-08-18T14:52:17 < zyp> dongs, isn't f429 disco also 100qfp? IIRC that has sdram
2015-08-18T14:52:28 < ReadError> But, TG told me that they need to fix the software in the device used to fix the software in other software? are you saying they are lying ?
2015-08-18T14:52:38 < karlp> I think they're totally working on an unrelated product, and all of this tooling and shit they're building if ro that project.
2015-08-18T14:52:47 < karlp> likewise for all their web software shitz
2015-08-18T14:52:59 < dongs> karlp: what is this amazing trollproj they're wokrin on
2015-08-18T14:53:10 < dongs> ok so yeah 427 has sdrma
2015-08-18T14:53:17 < ReadError> arent they already planning a new one?
2015-08-18T14:53:24 < dongs> zano 2.0
2015-08-18T14:53:24 < karlp> no idea, but I think they're clearly spending big in areas unrelated to zano.
2015-08-18T14:53:26 < ReadError> i thought you posted something about it, like a bigger one
2015-08-18T14:53:27 < dongs> twice the vaporware
2015-08-18T14:53:49 < Yoduza> why xilinx cost like stm32 ?
2015-08-18T14:54:00 < ReadError> zano 42.stoned
2015-08-18T14:54:01 < karlp> why apples cost less than bananas?
2015-08-18T14:54:16 < Yoduza> karlp LOL
2015-08-18T14:54:34 < PeterM> because you have to pay queenslanders to bend the bananas but nobody needs to bend apples
2015-08-18T14:55:26 < Yoduza> because 99% of planet people need food more then tv and airplanes
2015-08-18T14:56:22 < Yoduza> 1 banana = 1 airplanes . Golden Age matherf..
2015-08-18T14:57:08 < Yoduza> Age of Putler :D
2015-08-18T14:57:26 < Yoduza> planet need nuclear relax :D
2015-08-18T14:59:35 < Yoduza> after nuclear relax 1 banana would be cost like 100 airplanes :D
2015-08-18T14:59:58 < scrts_w> wtf are you talking here?
2015-08-18T15:00:28 < Yoduza> cause 1 stm cost like 1 Spartan
2015-08-18T15:01:09 < Yoduza> stm32 must cost $0.00000000000001 per chip
2015-08-18T15:02:12 < Yoduza> in Ukraine it cost 100 bananas per 1 chip
2015-08-18T15:02:18 < dongs> Yoduza: are you ESL
2015-08-18T15:02:26 < Yoduza> ESL ?
2015-08-18T15:02:35 < dongs> ukraine doesn't actually nEED STM32 or xilinx
2015-08-18T15:03:09 < Yoduza> dongs really ? What about my last work chief brother, who work in top management in xilinx ? :D
2015-08-18T15:03:32 < dongs> why dont you ask him why zano is expensive
2015-08-18T15:03:39 < dongs> err, xilinx
2015-08-18T15:03:41 < dongs> fucking zano
2015-08-18T15:03:46 < dongs> thats what i get for typing without looking
2015-08-18T15:04:13 < Yoduza> ZanDongs looks like China :D

2015-08-18T15:07:00 < dongs> Yoduza: look into waveshare stm32 devboards
2015-08-18T15:07:07 < dongs> they have some coreboards that are cheap

2015-08-18T15:07:31 < Laurenceb_> zano
2015-08-18T15:07:32 < scrts_w> because you're probably talking about spartan 6
2015-08-18T15:07:46 < scrts_w> and the other thing is: what can you do on LX4 part?
2015-08-18T15:07:50 < scrts_w> barely something...
2015-08-18T15:07:52 < dongs> $14-16 for a F103 core board
2015-08-18T15:07:58 < Yoduza> spartan 6LX150 cost $250 here

2015-08-18T15:20:18 < Yoduza> dongs, make array for 360*10 symbols and connect memory via SPI or I2C
2015-08-18T15:20:28 < dongs> Yoduza: not enough IO pins
2015-08-18T15:20:57 < Yoduza> dongs, make translator like direct map
2015-08-18T15:22:08 < dongs> Yoduza: how about I2C eeprom
2015-08-18T15:22:13 < Yoduza> dongs what kind of memory do you use ?
2015-08-18T15:22:15 < dongs> and read it each time I need a value
2015-08-18T15:22:20 < dongs> will that be fast enough
2015-08-18T15:22:26 < Yoduza> eeprom, i dont think so
2015-08-18T15:22:27 < dongs> faster than calculating sin() in asm
2015-08-18T15:22:57 < Yoduza> use DDR3 memory for all of your code
2015-08-18T15:23:16 < Yoduza> 100 chips on one DDR3 memory
2015-08-18T15:24:08 < Yoduza> dongs, do you know how work DMA ?
2015-08-18T15:24:49 < Yoduza> dumned kids..
2015-08-18T15:26:10 < Yoduza> eeprom vs ddr3 :D 65Kb vs 1GB
2015-08-18T15:26:48 < Yoduza> ddr3 memory cost today $.1
2015-08-18T15:27:05 < Yoduza> eeprom cost $2
2015-08-18T15:30:31 < Laurenceb_> yet ddr3 cards use eeprom
2015-08-18T15:30:41 < Laurenceb_>  *inception*
2015-08-18T15:30:56 < Yoduza> you kidding ?
2015-08-18T15:31:31 < Laurenceb_> no
2015-08-18T15:31:40 < Laurenceb_> there is usually eeprom for config

2015-08-18T17:17:22 < dongs> micromouse competition is heating up
2015-08-18T17:17:30 < dongs> some guy submitted a pcb with FPGA and DDR on it
2015-08-18T17:17:32 < dongs> for micromouse
2015-08-18T17:18:00 < upgrdman_> looking through Code Analysis settings. seems that some people thing a return value should ALWAYS be surrounded with parenthesis?
2015-08-18T17:18:16 < dongs> no
2015-08-18T17:18:17 < dongs> they're just dumb
2015-08-18T17:18:20 < dongs> why would that matter
2015-08-18T17:18:26 < upgrdman_> good. same here.
2015-08-18T17:18:27 < dongs> you know one thing you DO wanna surround with praenthesis
2015-08-18T17:18:29 < dongs> is #defines
2015-08-18T17:18:37 < upgrdman_> ya i know about that
2015-08-18T17:18:40 < dongs> #define COCKS (somecrap+1)
2015-08-18T17:18:45 < upgrdman_> dat order of operations
2015-08-18T17:18:46 < dongs> cuz if you don't and you hafe return COCKS*2
2015-08-18T17:18:47 < dongs> etc

2015-08-18T17:32:04 < dongs> they cloned sony timer.
2015-08-18T17:32:13 < upgrdman_> ?
2015-08-18T17:32:23 < dongs> I am not concerned about those who are trying to discredit us. They have been there from the outset. We have something they want and they don't have it or whatever the reason, trolls exist everywhere. I heard a leading journalist say "Don't read the comments" and it is a saying amongst journalists apparently. We stay fast and keep ourselves focused on the product.
2015-08-18T17:33:01 < dongs> Might I also take the time to point out that we are only 6 weeks behind our original publicised schedule considering this is a greater than 12 month project, that is less than 10% overrun and on a project of this size, that is minor.
2015-08-18T17:34:21 < upgrdman_> i should copy paste this zano stuff into my notes for when i need to blow people off
2015-08-18T17:35:23 < dongs> Finally before I log off, respect is important. I understand that some of you feel we haven't shown you the respect you deserve through lack of communication, I respect that and take that on board. Now if we turn the tables, might I cite and old saying. "You catch more flies with honey than vinegar" and it simply means if you want something, being polite and respectful is much more likely to get you what you want than taking the vinegar approach. If you criticise peo

2015-08-18T17:45:35 < upgrdman_> are there any ptc fuses that act kinda like fuses? like trip instead of just limit current
2015-08-18T17:46:17 < karlp> do you just mean a surface mount fuse? or what?
2015-08-18T17:46:27 < upgrdman_> a self-resetting fuse
2015-08-18T17:46:31 < dongs> thats a PTC
2015-08-18T17:46:58 < upgrdman_> dongs, a ptc fuse just limits current to its rating, no?
2015-08-18T17:47:28 < upgrdman_> e.g. a 1A ptc fuse, under overload conditions, which allows >1A for a short period, then clamp down to about 1A
2015-08-18T17:47:57 < jubatus> PTC is teh sux
2015-08-18T17:48:06 < dongs> upgrdman_: it will have very high resistance once its tripped
2015-08-18T17:48:14 < jubatus> and it will take forever to trip
2015-08-18T17:48:26 < upgrdman_> ? the ones i've fucking with allow their trip current forever
2015-08-18T17:49:00 < jubatus> the problem is they need a very high current to "trip"
2015-08-18T17:49:06 < jubatus> much more than the rated current
2015-08-18T17:49:14 < upgrdman_> e.g. 24V rail with 1A ptc. put a 1ohm resistor across the rail... and after a few seconds there's still an amp of current flow through the 1ohm resistor
2015-08-18T17:49:15 < jubatus> so probably your PTC isn't actually "tripping"
2015-08-18T17:49:31 < jubatus> yeah, 1A PTC will trip at 10A
2015-08-18T17:49:41 < upgrdman_> 24A is this case :)
2015-08-18T17:50:16 < jubatus> right, but that's momentary, once the PTC cools down you'll reach an equilibrium
2015-08-18T17:50:25 < upgrdman_> yes
2015-08-18T17:50:26 < upgrdman_> of 1A
2015-08-18T17:50:27 < jubatus> that's the 1A you're seeing
2015-08-18T17:50:31 < upgrdman_> yes
2015-08-18T17:50:34 < jubatus> PTC is teh sux
2015-08-18T17:50:48 < upgrdman_> are there any self-resetting fuses that will actually "blow" and unblow after maybe a minute?
2015-08-18T17:51:03 < upgrdman_> e.g. current drops close to 0A
2015-08-18T17:51:14 < jubatus> there are chips from TI for USB
2015-08-18T17:51:23 < jubatus> they actually monitor the current and turn off a mosfet
2015-08-18T17:51:36 < dongs> yeah, USB overcurrent thingies
2015-08-18T17:51:42 < dongs> but you can do same w/ptc and mosfet or relay
2015-08-18T17:52:26 < upgrdman_> how

2015-08-18T22:36:29 < Ecco> Do you guys know if it's possible (or even a good idea) to embbed a coin-cell battery *within* a hole drilled in the PCB?
2015-08-18T22:36:54 < Ecco> (To save some space on the total height of the final device)
2015-08-18T22:37:32 < jpa-> should work
2015-08-18T22:37:47 -!- trepidacious [~trepidaci@217.155.204.2] has quit [Quit: trepidacious]
2015-08-18T22:38:12 < Ecco> ok
2015-08-18T22:38:15 < zyp> I find it unlikely that you'll benefit from it
2015-08-18T22:38:15 < Ecco> :)
2015-08-18T22:38:29 < Ecco> Why? Because the PCB is very thin already?
2015-08-18T22:38:42 < zyp> usually coin cell holders sandwich the battery between the pcb and the holder
2015-08-18T22:38:43 < Ecco> So it's not worth the trouble vs putting the battery atop the PCB?
2015-08-18T22:38:51 < Ecco> You have a good point
2015-08-18T22:39:04 < jpa-> you can put chips upside down in holes also :P
2015-08-18T22:39:09 < Ecco> :-D
2015-08-18T22:39:12 < zyp> if you want it in a hole of the pcb, you need a holder that encloses the battery on both sides
2015-08-18T22:39:31 < Ecco> Well, coin cells can have a contact on their side
2015-08-18T22:39:32 < zyp> and parts of it then needs to be non-conductive, i.e. plastics
2015-08-18T22:40:01 < Ecco> So a huge via could do half the trick
2015-08-18T22:40:04 < zyp> and for the mechanical strength required, I don't think it'd be much thinner than the pcb in the first place
2015-08-18T22:40:26 < Ecco> well, yeah, you're very probably right
2015-08-18T22:40:42 < Ecco> It's not a genius idea anyway, so someone probably had it already and discarded it for some good reason
2015-08-18T22:40:42 < zyp> then consider the mechanics of getting the battery in and out
2015-08-18T22:41:16 < zyp> you might as well just go with a thinner pcb if you're concerned about total thickness
2015-08-18T22:41:24 < Ecco> Indeed
2015-08-18T22:41:45 < Ecco> BTW, are those supposed to be cheaper?
2015-08-18T22:41:53 < zyp> thinner pcbs? nah
2015-08-18T22:41:57 < Ecco> ok:)
2015-08-18T22:41:58 < upgrdman_> they also make coin cells with tabs tack welded on. some have the tabs parallels to the coin cell
2015-08-18T22:42:00 < upgrdman_> oops
2015-08-18T22:42:01 < zyp> the cost is in labor, not materials
2015-08-18T22:42:11 < Ecco> makes sense
2015-08-18T22:42:24 < upgrdman_> they also make coin cells with tabs tack welded on. some have the tabs parallels to the coin cell's top and bottom. you could solder one of those to the end of your board, hanging over the edge.
2015-08-18T22:42:36 < Ecco> upgrdman_: Kinda like this? http://juggernautmusic.com/wp-content/uploads/2014/08/CR2032-with-solder-tabs.jpg
2015-08-18T22:43:04 < Ecco> (well, the tabs are orthogonal to the battery plane, but they seem to be welded on)
2015-08-18T22:43:06 < upgrdman_> no
2015-08-18T22:43:07 < upgrdman_> like this
2015-08-18T22:43:08 < upgrdman_> http://www.mouser.com/ProductDetail/Renata/CR2032-MFR-FV/?qs=sGAEpiMZZMsPH4mqJ5uwwCP8E%2fpdTtHG
2015-08-18T22:43:12 < upgrdman_> ya
2015-08-18T22:43:16 < Ecco> ok gotcha
2015-08-18T22:43:20 < zyp> Ecco, actually, I'm considering thin pcb for a project I'm planning
2015-08-18T22:43:23 < upgrdman_> and just have it hug your pcb, sticking over the edge
2015-08-18T22:43:37 < Ecco> Thing is, I'd like to make the battery user-replaceable
2015-08-18T22:43:56 < Ecco> actually, to be accurate, user-placeable (device might not even come with a battery included)
2015-08-18T22:43:59 < zyp> I asked dongs about pricing, and he said that when it gets thinner than usual, then price will go up, not down
2015-08-18T22:44:07 < Ecco> oh, ok
2015-08-18T22:44:12 < Ecco> makes sense
2015-08-18T22:44:17 < upgrdman_> ya not sure about that. would need a holder, which added thickness
2015-08-18T22:44:24 < Ecco> out of curiosity, why were you looking for an extra-thin PCB?
2015-08-18T22:44:50 < Ecco> To make the overall device smaller?
2015-08-18T22:45:20 < zyp> to fit in a preexisting form factor
2015-08-18T22:45:24 < Ecco> oh ok
2015-08-18T22:45:32 < Ecco> sounds fun :)
2015-08-18T22:46:09 < jpa-> you could probably mount a holder like this   http://www.newark.com/productimages/standard/en_US/4589707.jpg   upside-down in a hole similar to the chips here  http://www.newark.com/productimages/standard/en_US/4589707.jpg
2015-08-18T22:46:13 < jpa-> err
2015-08-18T22:46:19 < jpa-> http://www.hembrow.eu/personal/103_4712.JPG   for second link
2015-08-18T22:46:56 < Ecco> Nice suggestion
2015-08-18T22:46:59 < Ecco> I'll look into it
2015-08-18T22:47:19 < Ecco> Maybe it's just simpler to go w/ a battery holder whose bottom plate is actually the PCB itself
2015-08-18T22:47:33 < jpa-> of course if you try to get the pcb commercially assembled, the p&p guys will be o_O
2015-08-18T22:47:38 < Ecco> :-D
2015-08-18T22:47:59 < upgrdman_> that's what chinagirl is for
2015-08-18T22:48:00 < Ecco> Regarding the picture you just linked
2015-08-18T22:48:05 < upgrdman_> we're creating jobs!
2015-08-18T22:48:05 < Ecco> Is it even possible to automate?
2015-08-18T22:48:16 < Ecco> I mean, the chips come in a reel, right?
2015-08-18T22:48:30 < jpa-> trays, pretty often
2015-08-18T22:48:41 < Ecco> Can the P&P machine flip the components before placing them?
2015-08-18T22:48:43 < jpa-> p&p machines can also pick loose chips so i guess it could work out just fine
2015-08-18T22:49:01 < jpa-> probably not

2015-08-18T22:50:22 < Ecco> What device is that?
2015-08-18T22:50:25 < Ecco> :-D
2015-08-18T22:50:30 < Ecco> wireless buttplug
2015-08-18T22:50:35 < Ecco> apparently

2015-08-18T22:55:51 < zyp> seeed can apparently do 0.6mm without extra cost
2015-08-18T23:05:45 < karlp> was there someone else here who'd written their own firmware for a china reflow oven?
2015-08-18T23:06:07 < zyp> hmm
2015-08-18T23:06:11 < Ecco> I've seen a few dudes who wrote a firmware for a toaster to turn it into a reflow oven
2015-08-18T23:06:15 < zyp> I were thinking about doing it for mine
2015-08-18T23:06:23 < zyp> and I came across somebody who did
2015-08-18T23:06:35 < karlp> jpa-: where were you earlier today when I was looking for those upside QFP images :)
2015-08-18T23:06:38 < zyp> but I don't remember if that was here or found by a google search
2015-08-18T23:09:03 < upgrdman_> anyone here do "manhattan style" prototypes? i seem to recall someone making a plug-cutter type of drill bit, but with an abrasive surface, instead of the normal metal cutting edges, but making little islands in copper clad boards?
2015-08-18T23:09:50 < upgrdman_> *for making
2015-08-18T23:10:50 < karlp> this dude made some new firmware for his china oven, just wondering if it was a dupe or anything: http://media.ccc.de/browse/conferences/camp2015/camp2015-6634-pushing_the_limits_of_diy_electronics.html#video&t=15

2015-08-18T23:13:46 < Yoduza> reballing masks ?
2015-08-18T23:14:02 < Ecco> I guess to re-use BGA ICs?
2015-08-18T23:14:23 < BrainDamage> take a bga chip without ball pins, mount on a stand, and mount the mask slightly spaced, then pour solder balls
2015-08-18T23:14:29 < BrainDamage> and they'll stick to the holes
2015-08-18T23:14:46 < BrainDamage> then you heat up the balls and they'll reflow to the bottom of the chip
2015-08-18T23:15:09 < BrainDamage> search for youtube videos

2015-08-19T00:17:03 < upgrdman_> ds2, i've done simple SMPSs before
2015-08-19T00:17:06 < upgrdman_> and more importantly
2015-08-19T00:17:20 < upgrdman_> i use a CV/CC psu to power my test shits
2015-08-19T00:17:35 < ds2> 10A is still potentially a lot of power
2015-08-19T00:17:52 < upgrdman_> amps... power... >_>
2015-08-19T00:18:04 < ds2> it won't be @ 0V....
2015-08-19T00:18:09 < upgrdman_> but srsly, i dont plan to push it that high. but the indctors can handle it
2015-08-19T00:18:35 < upgrdman_> probably set my psu to 5V 1A and go from there
2015-08-19T00:18:53 < upgrdman_> i also have a flir camera so i can be lazy about calculating power dissipation ;)

2015-08-19T00:26:27 < upgrdman_> i'll find one of mine
2015-08-19T00:27:40 < upgrdman_> shitty example, but heres a very simple one i did: http://farrellf.com/temp/induction_heater_revC.jpg
2015-08-19T00:28:41 < upgrdman_> hmm i dont have any photos of the more elaborate protos i've done
2015-08-19T00:29:06 < upgrdman_> but ya. you take copper clad. cut little squares. glue them onto a solid piece of copper clad, and solder your shit together
2015-08-19T00:29:22 < upgrdman_> less parasitic cap than a breadboard. MUCH more current handling. etc.
2015-08-19T00:30:06 < upgrdman_> yes
2015-08-19T00:30:42 < upgrdman_> its a computer. it runs linux. it doesnt require much power.
2015-08-19T00:30:58 < upgrdman_> SBCs are good for shit where you need a pc, but not a powerful pc
2015-08-19T00:31:12 < upgrdman_> e.g. a simple web server, vpn server, file server, etc.
2015-08-19T00:31:41 < upgrdman_> well you have a few gpios

2015-08-19T00:32:19 < upgrdman_> GargantuaSauce, well ya
2015-08-19T00:32:37 < upgrdman_> k1 is used in some tablets, right?
2015-08-19T00:32:43 < GargantuaSauce> yeah
2015-08-19T00:34:09 < GargantuaSauce> thing can crank out like 300 gigaflops with cuda
2015-08-19T00:34:15 < GargantuaSauce> i have it transcoding 4 video streams
2015-08-19T00:34:26 < upgrdman_> nice
2015-08-19T00:35:02 < upgrdman_> is cuda a big thing to wrap your head around, or is it just like normal programming but with fucktons of "threads" ?
2015-08-19T00:36:16 < GargantuaSauce> it's reasonably straightforward
2015-08-19T00:36:40 < GargantuaSauce> there is sort of a hierarchy of parallelization you need to get familiar with
2015-08-19T00:36:50 < GargantuaSauce> different tiers of memory sharing etc
2015-08-19T00:36:54 < zyp> you can't really think of it as threads
2015-08-19T00:37:26 < zyp> I mean, you can, but those threads will be doing the same thing, just on different data
2015-08-19T00:37:49 < upgrdman_> k
2015-08-19T00:38:46 < zyp> and this includes branching
2015-08-19T00:40:12 < upgrdman_> kinda reminds me of vector operations on a cpu
2015-08-19T00:40:32 < zyp> in my understanding, when a gpu needs to do something like an if/else expression, it computes both branches on all threads, and then picks the appropriate result in each
2015-08-19T00:41:38 < GargantuaSauce> yeah simd instructions are very much in the same vein
2015-08-19T00:47:58 < zyp> it's kinda natural when you consider what a gpu is designed to do
2015-08-19T00:48:10 < upgrdman_> ya

2015-08-19T02:06:07 < dongs> that was my first thought
2015-08-19T02:06:11 < Getty> if you display the return value as hex representation you get the right decimal representation, does that make sense?
2015-08-19T02:06:14 < zyp> guess they're being tested in the environment where they belong
2015-08-19T02:06:33 < dongs> funny how he mentions GPS

2015-08-19T02:33:13 < dongs> One thing to note, in the video I mention that "we cannot manually test each and every ZANO, so no test rig, no ZANOs". For the record, this is not because we're too lazy to test thousands of ZANOs. We require the automated process to make sure each and every ZANO is calibrated to the same uniformed values.
2015-08-19T02:33:19 < dongs> We also show some b-roll of some naked ZANO's being assembled. Obviously all the boards are loaded by the pick and place machine at Camtronics Vale, however, certain components must be hand loaded and final assembly is done by hand.

2015-08-19T03:03:25 < karlp> needed the space? couldnt use bootloader in final I take it?
2015-08-19T03:03:55 < dongs> no it was literally just to test stuff, no real purpose. there's a rom bootloader in STM8 just like on STM32
2015-08-19T03:04:12 < dongs> i think it needs fairly close PCB tolerances to make this work
2015-08-19T03:04:15 < dongs> esp drills
2015-08-19T03:05:01 < dongs> i wouldn't use this in production or for 0.5mm pitch stuff.
2015-08-19T03:05:35 < ds2> speaking of PCBs - any cheap vendors for 6L, 4/4 stuff?
2015-08-19T03:06:02 < dongs> define cheap?
2015-08-19T03:06:36 < karlp> that video I linked from ccc earlier was talking abot 6 and 8l pool services near the end
2015-08-19T03:06:43 < ds2> sub $400 for 3 peices?
2015-08-19T03:07:15 < dongs> thats kinda rough. depends on size, but it would be close
2015-08-19T03:08:02 < ds2> is it the 6L or the 4/4 the problem?
2015-08-19T03:08:21 < dongs> 6L, 4/4 is no p[roblem
2015-08-19T03:08:35 < ds2> I mean problem for cost
2015-08-19T03:08:41 < dongs> correct
2015-08-19T03:09:02 < ds2> most cheap pools stop at 4L
2015-08-19T03:09:13 < dongs> i doubt cheap pools do 4/4 either

2015-08-19T13:19:04 < chipsMonstret> Hi, I'm trying to get a STM32L1 discovery-board working with CubeMX and CooCox. I'm having some trouble... It does not seem to get to running main(). How do I know the correct target for the precompiler? I have gotten it compiling using "STM32L152xB", but I'm thinking that might be the problem? When I try to debug I get "No source available for "" ". Any thoughts? :)

2015-08-19T13:33:46 < upgrdman> is there a word for "three decades" ? like "there should be a comma separating three-decade-chunks" ... like 1,000,000
2015-08-19T13:35:16 < karlp> heh, dealing with china again?
2015-08-19T13:35:28 < karlp> they put separators on 10k or something right?

2015-08-19T13:35:36 < upgrdman> me? no. just trying to figure out how to phrase a comment in my code
2015-08-19T13:36:17 < karlp> hope you're in the front end.  ze germans and scandis want a . not a ,
2015-08-19T13:36:42 < karlp> use _ like haskell or verilog or whatever it is that ignores them in numeric literals :)
2015-08-19T13:36:48 < upgrdman> its a personal project. not worried about locales
2015-08-19T13:37:09 < karlp> what, are you racist or something?
2015-08-19T13:37:24 < upgrdman> no but im american, and the only person who will use this code
2015-08-19T13:37:38 < upgrdman> so im not worried about appeasing the hitler-loving germans, etc.
2015-08-19T13:37:39 < upgrdman> ;)
2015-08-19T13:38:04 < karlp> then who needs comments then at all, amirite?
2015-08-19T13:38:23 < upgrdman> fair enough
2015-08-19T13:38:33 < upgrdman> ANYWAY is there a fucking word for three-decades?
2015-08-19T13:39:21 < karlp> just call it a thousands separator
2015-08-19T13:39:31 < upgrdman> that works. thanks

2015-08-19T17:56:50 < __rob2> hello, not used the timers for external capture on the stm32 before, so I'm just wondering about PWM capture mode
2015-08-19T17:57:03 < __rob2> I want to capture the duty cycle, and period
2015-08-19T17:57:24 < __rob2> do I need multiple external pins for the input signal ?
2015-08-19T17:58:04 < __rob2> with 3 timers to capture this, or can this all be input on a single pin ?
2015-08-19T17:58:28 < upgrdman_> i have not done that, but you should only need one pin and one channel of one timer
2015-08-19T17:58:39 < upgrdman_> iirc theres an example in the reference manual showing how to do it
2015-08-19T17:58:46 < __rob2> right, but I need to trigger on both edge transistions
2015-08-19T17:59:08 < upgrdman_> i recall some example that showed to to measure the period and high time
2015-08-19T17:59:12 < upgrdman_> in the f4 ref man

2015-08-19T19:40:09 < zyp> hmm, only two lanes

2015-08-19T19:40:34 < zyp> considering four can do 1080p
2015-08-19T19:41:10 < emeb> Tectu: how fast do the LEDs ramp up to full "on"? make sure that your PWM duty cycle is much more than that to ensure linear brightness control.
2015-08-19T19:41:42 < emeb> how much noise can you stand in you power supply from LED current switching?
2015-08-19T19:41:52 < Tectu> emeb, noise is no issue at all
2015-08-19T19:42:11 < zyp> hmm, two lanes, 500 Mb/s per lane
2015-08-19T19:42:22 < Laurenceb> upgrdman_: yeah
2015-08-19T19:42:22 < emeb> make sure PWM frequency is high enough that it won't cause annoying visible blinking.
2015-08-19T19:42:34 < Tectu> emeb, I guess that is everything > 100 Hz?
2015-08-19T19:42:45 < emeb> usually yes
2015-08-19T19:43:01 < Tectu> emeb, is other value you mentioned first something I would grab from the LEDs datasheet or...?
2015-08-19T19:43:03 < emeb> WS28xx runs about 400-500Hz IIRC
2015-08-19T19:43:57 < emeb> Tectu: most LEDs turn on pretty fast, but if you run the PWM too fast then they don't get to full brightness before you turn them off again.
2015-08-19T19:44:08 < emeb> Don't know if that's normally something that's spec'd tho
2015-08-19T19:44:28 < zyp> I'd imagine the ramp time of the transistors driving the leds matters too
2015-08-19T19:44:34 < Tectu> so it is more of a tria´n´error thing>
2015-08-19T19:44:36 < Tectu> ?
2015-08-19T19:44:53 < emeb> if you're driving them with GPIO outputs those are pretty fast.
2015-08-19T19:45:05 < emeb> but if you've got external buffers yeah.
2015-08-19T19:45:28 < Tectu> got some BC517 between the GPIO and the LED
2015-08-19T19:45:44 < Tectu> it´some jumbo let stuff that afaik has 6 separate LEDs inside the actual 20mm LED casing
2015-08-19T19:45:53 < Tectu> stuff for separators in a huge 7-seg clock
2015-08-19T19:46:15 < emeb> ah
2015-08-19T19:46:32 < emeb> you're probably fine with 100Hz - 1kHz rates.
2015-08-19T19:46:37 < zyp> Tectu, consider another point: every time you switch, you waste some power to heat the transistors
2015-08-19T19:47:11 < emeb> why do you hate the planet?
2015-08-19T19:47:15 < Tectu> zyp, agreed. but this is some 240VAC powered 15cm 7-segment display clock. not sure if I am going to care about those 10mW ;)
2015-08-19T19:47:35 < Tectu> zyp, but thanks for the remark. did not really think of that.
2015-08-19T19:47:50 < Tectu> I guess I am gonna start with 500Hz and see how things go from there
2015-08-19T19:48:19 < zyp> well, once you're past the flicker threshold, there's not really any advantages in going further
2015-08-19T19:48:49 < zyp> more wasted power, less pwm resolution due to a lower timer count, etc…
2015-08-19T19:48:57 < Tectu> okay, thanks!

2015-08-19T20:03:53 < ColdKeyboard> I'm guessing that answer is no but is there a way to define a string of chars with "dynamic length" ?
2015-08-19T20:04:22 < ColdKeyboard> Like string[] = "something"; string[] += " else" to give "something else" ?
2015-08-19T20:04:29 < zyp> depends
2015-08-19T20:05:54 < ColdKeyboard> I'm creating a GET request for the HTTP so It would be much easier to have dynamic string so I can just shove data into it, then use strlen($string) and pass it to ESP8266
2015-08-19T20:06:17 < zyp> if you want to do anything with dynamic length, you need some sort of dynamic memory
2015-08-19T20:06:56 < zyp> well, no, you don't want to do that
2015-08-19T20:07:10 < upgrdman_> or a super long c-string that you use as a buffer to cat to
2015-08-19T20:07:16 < zyp> what you want to do is just allocate a big buffer, and then fill it in piecewise
2015-08-19T20:07:29 < ColdKeyboard> I see, then the better thing would be to define a string[300] and just terminate it with \0 so I can get correct strlen() ?
2015-08-19T20:07:36 < upgrdman_> yes
2015-08-19T20:07:44 < ColdKeyboard> Great. Thanks! :)
2015-08-19T20:07:55 < zyp> it's a better solution anyway
2015-08-19T20:08:25 < zyp> even with dynamic memory, extending the size of a buffer is a hassle
2015-08-19T20:09:15 < zyp> because it often results in allocation a larger buffer, copying all the content from the old buffer, then freeing the old buffer
2015-08-19T20:09:23 < zyp> and you don't want all that copy overhead
2015-08-19T20:09:56 < ColdKeyboard> I agree, and I think it's just too much work for a simple string that I can free as soon as I send it :)
2015-08-19T20:10:21 < zyp> so even with dynamic memory, it's often a good idea to just allocate more than you need

2015-08-19T21:07:04 < upgrdman_> guessing you left a \0 in there somewhere
2015-08-19T21:07:39 < ColdKeyboard> upgrdman_: Yes, I tought I can use it so that strlen will return correct lenght?

2015-08-19T21:09:24 < upgrdman_> wait what youre using strcpy
2015-08-19T21:09:32 < upgrdman_> go this:
2015-08-19T21:09:41  * ColdKeyboard facepalms...
2015-08-19T21:09:49 < upgrdman_> strcpy for first part of the string
2015-08-19T21:09:55 < upgrdman_> then strcat to append to that as needed
2015-08-19T21:10:25 < upgrdman_> when done, use the cstring, then restart with strcpy to reset your buffer, then strcat to append again...
2015-08-19T21:11:07 < upgrdman_> and you should never need to manual add a \0 unless you want to manually clip an existing cstring
2015-08-19T21:17:35 < ColdKeyboard> Alright, It's concatenating now. Thanks a lot! :)
2015-08-19T21:17:54 < ColdKeyboard> I just need to figure out what's wrong with the query when I assemble it via code vs. manual one that works :)

2015-08-19T22:02:26 < Ecco> ok
2015-08-19T22:02:30 < Ecco> how much bigger?

2015-08-19T22:03:14 < Ecco> thanks
2015-08-19T22:03:27 < Strogg> a lot of parts will have one in the datasheet.  If not there, you can usually find it on their website
2015-08-19T22:03:31 < Strogg> what's the part?
2015-08-19T22:03:36 < Ecco> STM32F401

2015-08-19T22:05:51 < Strogg> there's a summary datasheet, a reference manual, a peripheral summary.  there should be one about the mechanical aspects too

2015-08-19T22:48:30 < upgrdman_> ColdKeyboard, iirc c treats arrays are automatic pointers.
2015-08-19T22:48:40 < upgrdman_> so just take int[] as an argument
2015-08-19T22:48:52 < upgrdman_> and give it myArray as an argument (no [])

2015-08-19T22:49:14 < englishman> The pins can only go one way since the attachment point is on one end

2015-08-19T23:00:09 < upgrdman_> ColdKeyboard, payload[0] is the first element of the array. not the entire array
2015-08-19T23:01:15 < upgrdman_> if payload[] is an ascii string, with null termination, then just use strcat(query, payload)
2015-08-19T23:01:25 < ColdKeyboard> upgrdman_: I'm trying to concatenate value of the payload[0] to the extisting string but now I realize that I have to make a function that will return string representation of the payload[i] integer :)
2015-08-19T23:02:01 < zyp> uh, wat

2015-08-19T23:04:49 < zyp> Ecco, I always design symbols with a logical grouping of pins, which seldom comes close to resembling the physical layout
2015-08-19T23:06:15 < englishman> Like one part for portA and another for portB? Or another way

2015-08-19T23:07:20 < zyp> I usually put supply pins on top left side of a symbol, ground pins on bottom left, then signals get grouped by whatever makes sense
2015-08-19T23:07:40 < zyp> for stuff with IO banks, I make each big bank a separate subpart

2015-08-19T23:52:58 < upgrdman_> AFs, etc.
2015-08-19T23:53:03 < upgrdman_> ADC channel #'s...
2015-08-19T23:53:08 < zyp> uh, no.
2015-08-19T23:53:30 < upgrdman_> you don
2015-08-19T23:53:32 < upgrdman_> oops
2015-08-19T23:53:42 < upgrdman_> you don't like a full sentence next to each pin? ;)
2015-08-19T23:54:13 < zyp> the AF table consumes several pages of the datasheet, you simply can't fit that into a schematic symbol in a good way
2015-08-19T23:54:59 < upgrdman_> well you dont go into full detail
2015-08-19T23:55:09 < zyp> and I don't feel like making a tailored symbol for each project with the generic names replaced by the actually used AF either
2015-08-19T23:55:17 < upgrdman_> you do something like "PB11/MOSI/TIM3CH2" etc
2015-08-19T23:56:04 < zyp> I know, that's what I'm arguing is silly
2015-08-19T23:56:33 < upgrdman_> i find it helpful when laying out a schematic. so you can get a feel for what pins could be used with a timer, etc.
2015-08-19T23:56:49 < upgrdman_> then use the datashit/ref man to confirm and get details
2015-08-19T23:57:09 < zyp> I really prefer PA0 to PA0/USART2_CTS/TIM2_CH1_ETR/TIM8_BKIN/TIM8_ETR/TSC_G1_IO1/COMP1_OUT
2015-08-19T23:57:22 < zyp> oh, wait
2015-08-19T23:57:32 < upgrdman_> also useful when you need to do dirty hacks. "fuck i need a pin for uart rx... oh these can be used."
2015-08-19T23:57:49 < zyp> PA0/USART2_CTS/TIM2_CH1_ETR/TIM8_BKIN/TIM8_ETR/TSC_G1_IO1/COMP1_OUT/ADC1_IN1/COMP1_INM/RTC_TAMP2/WKUP1/COMP7_INP
2015-08-19T23:58:01 < zyp> that's all functions available on PA0 on that particular chip
2015-08-19T23:58:05 < upgrdman_> :)
2015-08-19T23:58:46 < upgrdman_> you could be more generic. like PA0/USART/TIM2/TIM8/TSC/COMP1/ADC/RTC
2015-08-19T23:59:03 < upgrdman_> just to give you a brief description
2015-08-19T23:59:50 < zyp> listing all functions on all pins is unwieldy, listing only some functions on all pins means you need to take time to cherry pick, and being an incomplete list it'd be rather useless
--- Day changed Thu Aug 20 2015
2015-08-20T00:00:19 < zyp> and whatever you list, the AF table in the datasheet will still be more readable and faster to look up
2015-08-20T00:00:43 < upgrdman_> just screenshot the table and paste it into the schematic ;)

2015-08-20T01:32:23 < ColdKeyboard> How can I pass an integer to the function and then return string and save it into char array?
2015-08-20T01:32:49 < Fleck> ghh
2015-08-20T01:32:59 < zyp> ColdKeyboard, you can't return a string really
2015-08-20T01:33:03 < ColdKeyboard> fox example I call hex2str(8) and the return value would be string "0x08" and I want to store it inside char[] array :)
2015-08-20T01:33:17 < Fleck> you return pointer to char array usually
2015-08-20T01:33:28 < zyp> better to pass in a pointer to the relevant position in the array and have the function write it there directly
2015-08-20T01:33:42 < zyp> Fleck, no, you don't, because you have nowhere to allocate it
2015-08-20T01:34:07 < ColdKeyboard> I tried to write my function that would make static char[4] inside function and then return the pointer value of that string but it seems to hang my code in infinite loop :\

2015-08-20T05:27:16 < jadew> Android, iOS
2015-08-20T05:28:37 < jadew> depends on how many and how old
2015-08-20T05:29:08 < jadew> you might end up downloading some opensource project that only compiles with X version

2015-08-20T05:30:03 < jadew> from what I see in the install options, I don't get C# as an option
2015-08-20T05:30:22 < jadew> yeah
2015-08-20T05:31:03 < jadew> I think it's probably a good idea to get the vs community 2013 full install package while it's still online
2015-08-20T05:31:06 < jadew> if it still is
2015-08-20T05:31:36 < jadew> R2COM, sure, maybe it can work with other git repos too
2015-08-20T05:31:47 < jadew> don't see why not, you don't have to use it
2015-08-20T05:33:09 < jadew> not automatically
2015-08-20T05:33:29 < jadew> you have to actually add it and I'm sure VS won't add them without letting you know
2015-08-20T05:33:38 < jadew> also, github has paid accounts, so you can have private stuff too
2015-08-20T05:34:03 < jadew> R2COM, you can have a local git server
2015-08-20T05:34:32 < jadew> but git works locally by design, you have a local repository (in the folder you work in) and you commit changes to it
2015-08-20T05:34:49 < jadew> then when you think you got something, you push them to the remote server
2015-08-20T05:35:15 < jadew> well, if you use github, you tell it that your remote server is github
2015-08-20T05:35:17 < ReadError> you can setup gitlab
2015-08-20T05:35:32 < ReadError> if you wanted a fancy interface
2015-08-20T05:35:49 < jadew> R2COM, I think plain git would do the job
2015-08-20T05:35:59 < jadew> R2COM, get tortoise git and play a bit with it
2015-08-20T05:36:43 < ReadError> sorestree!
2015-08-20T05:36:59 < ReadError> R2COM synology has a gitserver too
2015-08-20T05:38:20 < GargantuaSauce> yeah atlassian sourcetree is the best git gui for a winfag
2015-08-20T05:39:31 < ReadError> tortoise git has a nice merge tool for conflicts though
2015-08-20T05:40:16 < jadew> ReadError, not sure how nice it is, I find it a bit confusing
2015-08-20T05:40:36 < ReadError> jadew its not bad once you figure it out
2015-08-20T05:40:57 < ReadError> you just scroll through and select 'use mine' or 'use theirs' or 'use both' for the red/green
2015-08-20T05:41:34 < jadew> ReadError, yeah, but I couldn't figure out yet what those icons on the margin and the colors are trying to tell me so I just resolve conflicts in a text editor
2015-08-20T05:42:05 < ReadError> oh I just highlight the lines I want and right click
2015-08-20T05:42:06 < jadew> R2COM, yes
2015-08-20T05:42:19 < ReadError> once you do it a few times its pretty nice and quick
2015-08-20T05:50:02 < karlp> bitbucket's tortoise alternative was relatively popular at work, sourcetree or something?

2015-08-20T13:17:24 < upgrdman> something like this would be great, if the usb cable was right angled

2015-08-20T14:07:13 < emeryth> zyp: maybe he needs to plug in his ethernet adapter and card reader :P
2015-08-20T14:08:03 < zyp> I don't think there's any MBP without a built in card reader
2015-08-20T14:09:53 < emeryth> dammit, I need to update my apple bashing techniques
2015-08-20T14:10:20 < zyp> you get a point for the ethernet adapter though
2015-08-20T14:10:58 < zyp> my MBP is old enough to still have one, but the newer ones don't, and I'm not sure how I feel about that
2015-08-20T14:12:30 < karlp> 802.11ac is ubiqutious right? you live in a wifi world? what would you need ethernet for? :)
2015-08-20T14:13:48 < zyp> I have a matchbox-sized wifi router that I usually bring when I travel
2015-08-20T14:14:34 < karlp> how does that actually work? what problem does that solve?
2015-08-20T14:14:48 < karlp> I see these tiny routers, and but I don't quite follow the use case
2015-08-20T14:14:48 < zyp> partly in case I encounter somewhere with wired ethernet but not wireless, and partly because I don't want to enter wifi credentials on all my devices when I can just bring my own
2015-08-20T14:15:26 < zyp> «all» in the context of travel usually means phone, laptop and kindle
2015-08-20T14:16:06 < karlp> it's the "getting wired but not wireless while travelling" bit I don't really see I guess :)
2015-08-20T14:16:27 < karlp> how good is the router at doign captive portal signin stuff?
2015-08-20T14:16:27 < upgrdman> karlp, ya i know. i bought this laptop because of the lcd. i FUCKING LOVE all the pixels. even today, two years later, windows laptops still have shit screens. the few with 4k are aimed at gamer fags so they have like a 15 minute battery life, and are like 4" thick
2015-08-20T14:16:48 < upgrdman> also 13" laptops are too small
2015-08-20T14:17:04 < upgrdman> seem like the only high quality windows laptops are 13" or smaller.
2015-08-20T14:17:51 < upgrdman> zyp, just for convenience. if i always need a hub, might as well make it small and attached.
2015-08-20T14:17:52 < zyp> karlp, I haven't encountered much of those, but the captive portal can't generally distinguish between a nat router and a normal client
2015-08-20T14:18:01 < upgrdman> and the periphs are not always the same
2015-08-20T14:18:21 < zyp> karlp, so the captive portal will just intercept the first request you make through the router
2015-08-20T14:18:47 < zyp> upgrdman, it's this «always need a hub» part that I'm curious about
2015-08-20T14:19:23 < upgrdman> well i have one two built in usb ports. because that pleases the ghost of steve jobs
2015-08-20T14:19:25 < upgrdman> and
2015-08-20T14:19:51 < zyp> yes, I also have two usb ports in my laptop, and I rarely find myself needing more
2015-08-20T14:20:03 < upgrdman> i often need some combo of: logitech mouse dongle, stlink2, xilinx programmer, anal discovery, etc.
2015-08-20T14:20:19 < emeryth> and one for charging your zano
2015-08-20T14:20:28 < upgrdman> and i might need to charge my phone via the laptop too
2015-08-20T14:20:36 < upgrdman> emeryth, indeed
2015-08-20T14:20:50 < zyp> haha, ok
2015-08-20T14:21:29 < upgrdman> and if i need more bandwidth, i migth use my chipscope AND the anal discovery at the same time

2015-08-20T20:11:58 < chipsMonstret> Ecco this might be a ugly hack. But you can draw it in your software of choice, export dxf, import DXF to PCB-file (in Altium), copy footprint to component lib
2015-08-20T20:13:08 < chipsMonstret> There should be a better way of doing it tho...
2015-08-20T20:13:10 < Ecco> Indeed

2015-08-20T20:52:51 < upgrdman_> how is 0xABCD less clear
2015-08-20T20:53:46 < dos_fan]> if makes it obvious that value has component parts
2015-08-20T20:53:57 < dos_fan]> but ehh... never mind dude lol
2015-08-20T20:54:17 < upgrdman_> each bit is a flag in this variable. it's not like each nybble means one thing anyway

2015-08-20T20:56:32 < upgrdman_> using 0x or 0b notation would make sense. using a fuck ton of <<'s just makes it a bitch to read
2015-08-20T20:56:54 < dos_fan]> I disagree.

2015-08-21T00:16:43 < PeterM> then there are useability concerns  - with such a large perimeter area on the shapes and the shapes so close together, debris will make them much easier to accedentally connect

2015-08-21T03:11:19 < dongs> zyp, just found your stencil
2015-08-21T03:11:33 < zyp> :)
2015-08-21T03:11:57 < dongs> was quite a chore, i really need to figure out a way to store them
2015-08-21T03:12:19 < dongs> wonder if I can use a ring binder and have stencil place make holes in it for keeping htem
2015-08-21T03:12:23 < dongs> then i can kinda page through stuff
2015-08-21T03:12:32 < zyp> was about to suggest that
2015-08-21T03:12:36 < zyp> or a ring binder with pockets
2015-08-21T03:12:56 < dongs> pockets isnt really gonna  work cuz they get a bit nasty after some use, the plastic tape border around them wears out and gets crappy
2015-08-21T03:14:12 < zyp> hmm
2015-08-21T03:14:54 < zyp> I usually wipe stencils with isopropanol when I'm done using them
2015-08-21T03:15:57 < zyp> but I haven't figured out a way to store them either, usually I put them back in whatever wrapping I got it in, and then that goes wherever
2015-08-21T03:16:21 < zyp> since I mostly do one-offs it doesn't matter
2015-08-21T03:16:40 < dongs> yeah mine are clean too
2015-08-21T03:16:49 < dongs> i meant just the plastic border around them gets kinda crap
2015-08-21T03:17:01 < dongs> some of the shit i used 100s of times is quite crap
2015-08-21T03:17:03 < zyp> oh, right
2015-08-21T03:17:17 < zyp> most of mine are cuts without that border :p
2015-08-21T03:17:36 < dongs> no, its not framed. just tape around cut
2015-08-21T03:17:43 < zyp> yes, I know
2015-08-21T03:17:53 < dongs> way too easy to cut yourself wihtout that shit
2015-08-21T03:18:22 < zyp> well, you didn't add tape to the other edges when you cut out my layouts and sent them to me :p
2015-08-21T03:18:50 < dongs> yeah, tape only goes on standard ones I use that are liek 20x30cm
2015-08-21T03:19:33 < zyp> I know what you mean, I got a full sheet from you as well, that time work paid for it
2015-08-21T03:19:45 < zyp> but the rest are just cuts
2015-08-21T03:19:49 < dongs> anyway time to do your shit.

2015-08-21T05:11:11 < owl-v-> that's the "if" statement
2015-08-21T05:11:37 < owl-v-> yes
2015-08-21T05:11:55 < zyp> the thing is
2015-08-21T05:12:00 < zyp> these are all expressions
2015-08-21T05:12:16 < owl-v-> omg! O.O
2015-08-21T05:12:28 < zyp> this is all «expression;»
2015-08-21T05:12:40 < owl-v-> omg!! O.O
2015-08-21T05:13:25 < zyp> whether the expression does something useful or not doesn't change the fact that it's an expression
2015-08-21T05:13:33 < owl-v-> and the compiler ignores that expression?
2015-08-21T05:14:31 < owl-v-> does it works for all 'c' compilers?
2015-08-21T05:14:46 < zyp> well, first the compiler parses the expression, evaluates it
2015-08-21T05:17:02 < zyp> I'm not very familiar with compiler internals, but I assume it gets parsed into the tree structure like everything else
2015-08-21T05:17:10 < owl-v-> if the parser says 'nope, not a complete sentence' then it may throw errors, depends on the implementation
2015-08-21T05:17:22 < zyp> but it is complete
2015-08-21T05:17:47 < zyp> any literal is a valid expression, and any expression is a valid statement
2015-08-21T05:18:09 < upgrdman> fake & gay;
2015-08-21T05:18:22 < owl-v-> i don't think it's complete, but it seems the modern compiler ignoring it, or throwing "WARNINGS"
2015-08-21T05:18:41 < zyp> what about «i++;»?
2015-08-21T05:19:20 < dongs> god damn i anm not ready for this shit AT ALL
2015-08-21T05:19:35 < owl-v-> that's same as i+=1; or i=i+1; at the end of the statement.
2015-08-21T05:20:09 < owl-v-> upgradman, does your compiler throws any warning?
2015-08-21T05:20:22 < zyp> owl-v-, it does the same, but it is not the same
2015-08-21T05:20:44 < zyp> ok, here's a fun one, what about «i;»?
2015-08-21T05:20:46 < upgrdman> owl-v-, never tried. was just reading up on static code anal, and saw it
2015-08-21T05:22:44 < owl-v-> zyp, upgrdman: my compiler throws a warning, just like i predicted.
2015-08-21T05:22:57 < upgrdman> k
2015-08-21T05:23:18 < zyp> owl-v-, yes, because it's valid code
2015-08-21T05:23:25 < owl-v-> main.c:4:1: warning: expression result unused [-Wunused-value] //  ‘fun";
2015-08-21T05:23:33 < zyp> owl-v-, if it were invalid, it would throw an error, not a warning
2015-08-21T05:24:02 < owl-v-> zyp: if it can be ignored, whay bother throwing an error?
2015-08-21T05:24:32 < owl-v-> you can make it throw errors for all warnings
2015-08-21T05:25:11 < zyp> warnings aren't errors, warnings doesn't mean you're doing something invalid
2015-08-21T05:25:54 < zyp> gcc will warn if you mix bitwise operators without parantheses also, just because people tend to fuck up operator precedence when they do that
2015-08-21T05:26:58 < zyp> a warning is like the compiler telling you «uh, you're allowed to do this, but are you sure it's right?»
2015-08-21T05:27:21 < owl-v-> i was wrong about validity then, but again, it's not a full sentence.
2015-08-21T05:27:42 < owl-v-> maybe "fun" was stored in a stack memory, but never used in the program
2015-08-21T05:28:31 < owl-v-> my compiler said "unused-value"
2015-08-21T05:29:36 < zyp> well, yeah, usually you don't put in values that's not being used in any way
2015-08-21T05:29:47 < zyp> it's not illegal to do that, just pointless

2015-08-21T07:39:18 < emeb_mac> my grandfather was german

2015-08-21T07:40:46 < emeb_mac> had him running a stamping machine turning out shoe leather.
2015-08-21T07:41:09 < emeb_mac> didnt' send him home until years after the war was over, and then just because he was injured on the job.

2015-08-21T08:01:24 < emeb_mac> we'd rather just kill them outright
2015-08-21T08:02:43 < emeb_mac> may I direct your attention to the concept: Golgafrincham “B” Ark
2015-08-21T08:05:12 < emeb_mac> mechanically simple
2015-08-21T08:05:51 < emeb_mac> problem - the human body evolved to live on earth, in a gravity field, in an atmosphere, in a biological ecosystem, protected from radiation.
2015-08-21T08:06:11 < emeb_mac> take any one of those conditions away and things go to shit in a hurry.
2015-08-21T08:07:47 < emeb_mac> reproducing those conditions for the duration of a voyage to another planet would increase overall system complexity to a degree that it becomes impractical with current tech
2015-08-21T08:08:32 < emeb_mac> reproducing those conditions on another planet is virtually impossible.
2015-08-21T08:12:42 < emeb_mac> better to build a closed system with recycling and/or CO2 cracking.
2015-08-21T08:12:52 < emeb_mac> or even plants
2015-08-21T08:13:55 < emeb_mac> also need to break down water. food + O2 -> CO2 + H2O. gotta close the cycle.
2015-08-21T08:15:06 < emeb_mac> but still - the problem of radiation is a serious one. very tough to provide protection for worst-case radiation flux in space.
2015-08-21T08:15:18 < emeb_mac> we depend heavily on the Van Allen belts.
2015-08-21T08:15:46 < emeb_mac> you need several meters thick of shielding to protect.

2015-08-21T08:25:53 < emeb_mac> uh, so instead you would rather send people to another solar system, on a trip that could take thousands of years?
2015-08-21T08:26:15 < emeb_mac> and you're going to build a ship that's reliable enough to last that long?
2015-08-21T08:28:03 < emeb_mac> who gives a crap about the hull. that's the easy part. it's all the mechanical systems needed to maintain a livable environment.

2015-08-21T11:40:17 < ReadError> hmm this makefile is looking for raisonance stuff
2015-08-21T11:42:34 < Ecco> Hi!
2015-08-21T11:42:52 < Ecco> Is it safe to detect a connection between two GPIOs without adding a resistor inbetween?
2015-08-21T11:43:21 < Taxman> what do you want to do?
2015-08-21T11:43:27 < Ecco> Matrix keyboard
2015-08-21T11:44:23 < mtbg> one obviously must be configured as input
2015-08-21T11:44:27 < mtbg> then it is safe
2015-08-21T11:44:27 < Ecco> yes
2015-08-21T11:44:44 < Ecco> rows are outputs, columns are input
2015-08-21T11:44:46 < Taxman> or pull up input
2015-08-21T11:44:53 < Taxman> yes its safe
2015-08-21T11:45:03 < Ecco> I set the inputs as pull-down because I want to read "0" if no output drive them up
2015-08-21T11:45:06 < Ecco> Ok
2015-08-21T11:45:19 < Ecco> Is there an integrated resistor? Why won't the current be too high?
2015-08-21T11:45:37 < Taxman> where should the high current flow?
2015-08-21T11:45:58 < Ecco> from the output to the input
2015-08-21T11:45:59 < mtbg> the input itself has very high impedance
2015-08-21T11:46:03 < Ecco> oh ok
2015-08-21T11:46:10 < Ecco> ok I get it
2015-08-21T11:46:14 < mtbg> pull-up/down lowers it
2015-08-21T11:46:17 < Ecco> output -> ground = potential damage
2015-08-21T11:46:31 < Ecco> output -> input = no problem because input is High-Z
2015-08-21T11:46:32 < Ecco> right?
2015-08-21T11:47:05 < Taxman> yes
2015-08-21T11:47:44 < Taxman> but this is very basic that one should not connect a transistor directly to gnd and vdd

2015-08-21T11:50:19 < dongs> whats special about 330
2015-08-21T11:50:30 < Ecco> mtbg: WHen you said that an input marked as "pulled-down" has a lower resistance
2015-08-21T11:50:34 < dongs> just pick any other one, or pick 'generic 8051' and then select larger flashhetc?
2015-08-21T11:50:42 < Ecco> does that mean it's still safe to connect it to an output directly?
2015-08-21T11:50:55 < mtbg> yes, it is still in order of dozens kΩ
2015-08-21T11:51:01 < Ecco> allright, thanks

2015-08-21T12:03:47 < tekkkz> Hello! Can someone help me with my project? Can someone verify me/or test(/check/try), if this project works: https://www.dropbox.com/s/ssjwmb8pu2cnn0f/Procyon.tar.gz?dl=0 it should turn on the LED D2. At me it doesnt turn on this led so can you check it pls? its for stm32f103c8t6...
2015-08-21T12:04:49 < Fleck> tekkkz: pastebin main.c
2015-08-21T12:04:49 < Ecco> tekkkz: That's a pretty bad way to ask a question. I doubt you'll get any answer
2015-08-21T12:06:01 < Ecco> What are the minimal requirements to be able to interface an STM32 with openocd?

2015-08-21T12:06:25 < Ecco> I mean, what is the minimal set of pins I have to connect to an STM32 in order to be able to interact with it using OpenOCD?
2015-08-21T12:06:55 < Fleck> 2 :D
2015-08-21T12:07:05 < Fleck> well 3...
2015-08-21T12:07:18 < Fleck> GND, SDIO and CLK
2015-08-21T12:09:27 < tekkkz> Fleck, here: https://bpaste.net/show/8dc2ce31a7dd im using libopencm3
2015-08-21T12:10:24 < Ecco> tekkkz: I'd say you might have not enabled GPIO's clocks
2015-08-21T12:10:56 < Fleck> yeah, I don't see that part too...
2015-08-21T12:11:03 < Ecco> Fleck: Thanks
2015-08-21T12:11:12 < Ecco> I see the spec mentions a "TRACESWO" pin
2015-08-21T12:11:25 < Ecco> What kind of functionality does this one provide? How would it translate in OpenOCD?
2015-08-21T12:12:12 < Ecco> Also, on my discovery board, the "SWD" port has 6 pins. Why so many if only 3 do the job?
2015-08-21T12:13:00 < Fleck> tekkkz in basic steps you need: 1) enable GPIOx clock. 2) Configure Port/Pin as output. 3) toggle pin...
2015-08-21T12:13:32 < Fleck> Ecco: no clue, I never used anything else, only st-link v2 :), using openocd to flash/debug :)
2015-08-21T12:13:39 < Ecco> ok :)
2015-08-21T12:14:55 < tekkkz> oh yes id enabled it: line 69 IO_CFG_OUTPUT(LED_STATE); -> look at defines.h what it does
2015-08-21T12:16:41 < Fleck> Ecco: http://imgur.com/WYnEkIy
2015-08-21T12:17:12 < Ecco> Nice
2015-08-21T12:17:37 < Ecco> Oh also, another question
2015-08-21T12:17:56 < Ecco> All the demo board from ST that I've seen feature an external crystal
2015-08-21T12:18:08 < Ecco> I thought STM32 could run without one
2015-08-21T12:18:12 < Ecco> Why do they bother, then?
2015-08-21T12:18:29 < Fleck> it can, but internal oscilator is not so acurate
2015-08-21T12:18:40 < Fleck> *accurate
2015-08-21T12:18:48 < tekkkz> Fleck, can you keep helping me pls, i'm in a hurry
2015-08-21T12:18:58 < Fleck> tekkkz: I did
2015-08-21T12:19:05 < Ecco> tekkkz: Bad attidude mate
2015-08-21T12:19:23 < jpa-> Ecco: http://essentialscrap.com/tips/arm_trace/arm_itm.png   this is the kind of stuff you can get out of TRACESWO
2015-08-21T12:19:34 < tekkkz> sorry. But Fleck , i did all what you said
2015-08-21T12:19:37 < tekkkz> look at line 69
2015-08-21T12:19:39 < Ecco> What the hell am I looking at? :-D
2015-08-21T12:19:47 < jpa-> interrupts, trace messages, etc.
2015-08-21T12:20:03 < Ecco> What's a "trace message" ?
2015-08-21T12:20:23 < Ecco> And also, what software did you use to get this image?
2015-08-21T12:20:25 < jpa-> something emitted from software
2015-08-21T12:20:32 < jpa-> sigrok
2015-08-21T12:20:50 < Ecco> so kinda like printf-debugging?
2015-08-21T12:21:33 < jpa-> yeah
2015-08-21T12:21:35 < Ecco> Never heard of sigrok before. Seems sweet! I'll give it a try. Thanks for the pointer!
2015-08-21T12:22:35 < jpa-> ITM has hardware buffer for a few trace messages & the bitrates are slightly higher than typical UART rates, so the overhead is not as big as for printf() debugging
2015-08-21T12:23:00 < Ecco> ok, interesting. And I guess that also frees up an UART
2015-08-21T12:23:07 < Fleck> tekkkz: I can't help you more, I gave you basic steps, no go on and debug/read register states and find out why it doesn't work!
2015-08-21T12:23:20 < Fleck> s/no/now
2015-08-21T12:23:36 < jpa-> yeah, though you can always use also semihosting for debug messages if you feel like it.. though i think semihosting is even slower than uart
2015-08-21T12:23:51 < tekkkz> Fleck, but do you see that i exactly did all steps?
2015-08-21T12:24:04 < Fleck> No I don't!
2015-08-21T12:25:14 < tekkkz> i told you look at line 69!
2015-08-21T12:29:19 < Fleck> tekkkz: looks OK here, no clue!
2015-08-21T12:29:54 < tekkkz> Sorry fleck. So it is correct, yes: https://bpaste.net/show/ef0ec642ab89 or is something wrong at my set_mode ?

2015-08-21T12:54:42 < tekkkz> impossible. too much font on them
2015-08-21T12:54:55 < Ecco> tekkkz: I would advise, if possible, to buy a board from ST
2015-08-21T12:55:12 < Ecco> They're really cheap, and reliable. Life is too short to be wasted debugging crappy devboard
2015-08-21T12:55:19 < jpa-> tekkkz: probe?
2015-08-21T12:55:26 < jpa-> but yeah, why are you using a dev board without schematics?
2015-08-21T12:55:30 < tekkkz> yeah, but im just 17years, in a poor litle guy, i dont have money..
2015-08-21T12:55:39 < jpa-> st discovery costs $10
2015-08-21T12:55:42 < mtbg> you can also take a multimeter with buzzer and check pins with it
2015-08-21T12:55:44 < jpa-> how much did you pay for yours?
2015-08-21T12:55:48 < tekkkz> 2$
2015-08-21T12:55:54 < Ecco> what? :-D
2015-08-21T12:56:00 < Ecco> That's not even the price for shipping :)
2015-08-21T12:56:10 < tekkkz> man but the best would be to solder my own one... i have everything i need, i just need to buy the chip
2015-08-21T12:56:12 < jpa-> oh well, cheaper than the stm32 then
2015-08-21T12:56:15 < jpa-> just probe it up
2015-08-21T12:56:24 < Ecco> tekkkz: Nope, bad idea
2015-08-21T12:56:36 < Ecco> Buy a devboard from ST, really
2015-08-21T12:56:40 < tekkkz> nope. good idea ;) i have a reflow oven, so it would be good ;) here are the schematics. https://www.dropbox.com/s/c2qp5c7p3y8iprb/STM32.pdf?dl=0
2015-08-21T12:56:47 < Ecco> Building your own one means checking it is wired up correctly

2015-08-21T12:57:11 < tekkkz> the oven was 10$ ;)
2015-08-21T12:57:28 < Ecco> Yeah it's not, but it seems like a waste of time
2015-08-21T12:57:28 < jpa-> making a custom dev board may be waste of time but atleast it is a learning experience
2015-08-21T12:57:34 < tekkkz> whatever, look at the schematics.
2015-08-21T12:57:38 < dongs> lol that schematic is made in fucking protel99 or someshit
2015-08-21T12:57:41 < jpa-> you'll have to know how to wire up a STM32 anyway if you are going to do anything real with it
2015-08-21T12:57:44 < Ecco> INdeed, that's a very good learning experience, I agree

2015-08-21T12:58:44 < Ecco> In his case, if the led would not blink on an ST board, he would be positive that his code is wrong

2015-08-21T12:59:24 < Ecco> Yeah right
2015-08-21T12:59:30 < Ecco> But like was said a few days earlier
2015-08-21T12:59:38 < jpa-> "have two" :)
2015-08-21T12:59:40 < Ecco> Never save money on tools
2015-08-21T12:59:44 < Fleck> tekkkz: also, use multimeter to check where it is connected
2015-08-21T12:59:51 < jpa-> Ecco: eh, stupid advice
2015-08-21T12:59:55 < Ecco> Fleck: Dude, a multimeter is like $5!!!
2015-08-21T13:00:01 < jpa-> Ecco: because you can spend infinite amount of money on tools
2015-08-21T13:00:05 < Fleck> Ecco: so? :D
2015-08-21T13:00:07 < Ecco> Yeaaah of course :-D
2015-08-21T13:00:20 < Ecco> You know what I meant thought :)
2015-08-21T13:00:31 < jpa-> you mean "spend correct amount of money on tools"?
2015-08-21T13:00:59 < Ecco> I meant "buying reliable tool is a worthwhile investment"
2015-08-21T13:01:06 < jpa-> not always
2015-08-21T13:01:31 < Ecco> Well, sure, if you buy the best cyclotron ever that won't help you debug an STM32
2015-08-21T13:01:33 < jpa-> and it is very difficult to know what is reliable and what is not
2015-08-21T13:01:35 < tekkkz> i have a multimeter
2015-08-21T13:01:51 < tekkkz> im living in germany and last week at aldi there was one in the sells, i bought it, 10€
2015-08-21T13:01:55 < PaulFertser> For car or bike repair good mechanical tools are really, really nice to have.
2015-08-21T13:02:01 < jpa-> for example, i wouldn't say that the stlink of discovery board is particularly reliable
2015-08-21T13:02:30 < tekkkz> here the image of the board: https://mmi239.whatsapp.net/d/oR_UnafQzxehjMidfwoRLVXW9tk/AgQi_z64lf9nToZ_ddC1IYxswyqkd5BL2wIxnBoQpMfE.jpg
2015-08-21T13:02:44 < Ecco> Well, I've bought my share of crappy tools in the past (cheap ass multimeters for example)
2015-08-21T13:02:50 < tekkkz> you see the right green jumper and the fat white push-jumper? what are they doing?
2015-08-21T13:02:57 < Ecco> They all ended up in the trash and I eventually bought a good one
2015-08-21T13:03:03 < tekkkz> *i mean bottom, not right

2015-08-21T13:03:15 < jpa-> Ecco: i have a cheap multimeter, works fine
2015-08-21T13:03:19 < Ecco> Good for you :)
2015-08-21T13:03:25 < jpa-> so your advice doesn't really tell how to recognize crap
2015-08-21T13:03:34 < Ecco> Oh right, it doesn't
2015-08-21T13:03:37 < jpa-> of course "do not buy crap" is good advice, but not helpful advice
2015-08-21T13:04:08 < Ecco> Well, now that's the theoritcal job of brands
2015-08-21T13:04:19 < Ecco> You pay a premium, and hope to get a better product
2015-08-21T13:04:22 < mtbg> I think the traces are visible enough
2015-08-21T13:04:27 < Ecco> some brands are worth it, some aren't
2015-08-21T13:04:59 < mtbg> also
2015-08-21T13:05:08 < mtbg> I think the led is not connected to anything

2015-08-21T13:05:20 < mtbg> except resistor and some supply rail
2015-08-21T13:05:37 < mtbg> that is why they made "LED" pin on the pin header

2015-08-21T13:08:46 < tekkkz> nope, thats wrong
2015-08-21T13:08:57 < tekkkz> i cant light up the led with any other port+connection
2015-08-21T13:09:03 < tekkkz> so it must be for something else
2015-08-21T13:09:17 < tekkkz> and at the default firmware which was in it, the led also was burning

2015-08-21T13:11:46 < Fleck> tekkkz: no, it's just backwards soldered (low on pin will light the led, high will turn it off) - just a guess
2015-08-21T13:12:06 < tekkkz> ahh ok
2015-08-21T13:12:17 < tekkkz> btw, what is BOOT1 and BOOT0 doing?
2015-08-21T13:12:45 < mtbg> refer to reference manual
2015-08-21T13:13:07 < Ecco> tekkkz: Sets up how the device boots (from flash, from RAM, from internal bootloader)
2015-08-21T13:13:18 < Ecco> tekkkz: You should definitely read the datasheet
2015-08-21T13:13:30 < Ecco> It's not *that* long, and also you can skip parts you're not interested in
2015-08-21T13:13:43 < tekkkz> ok
2015-08-21T13:13:45 < tekkkz> btw
2015-08-21T13:13:58 < tekkkz> the big white jumper connects usb supply with board
2015-08-21T13:14:07 < tekkkz> and what is the green doing at the usb connector?
2015-08-21T13:14:32 < tekkkz> maybe its in the datasheet JP1, is this possible?
2015-08-21T13:18:41 < mtbg> JP6 looks as if it was on 3.3V supply to the microcontroller
2015-08-21T13:18:53 < mtbg> maybe for measuring Icc
2015-08-21T13:18:58 < Ecco> I have a question regarding the STLINKv2 embedded in a bunch of ST board
2015-08-21T13:19:05 < Ecco> here's the typical schematics : http://i.imgur.com/ouDhAA6.png
2015-08-21T13:19:33 < Ecco> Question: why are there resistors (R14, R15, R17, R20) before the connector (Header6)
2015-08-21T13:19:40 < tekkkz> mtbg, yeah, it has connection with 3v3, gnd and 2 others
2015-08-21T13:19:49 < tekkkz> so it is the boot0-boot1 connector maybe
2015-08-21T13:19:52 < Ecco> and *not* when going to the embedded STM32 (PA14, PA13, etc…)
2015-08-21T13:20:17 < mtbg> JP1 can be for boot stuff
2015-08-21T13:20:28 < tekkkz> ok wahtever i just left it connected
2015-08-21T13:20:39 < tekkkz> but i still dont know how to light up the led
2015-08-21T13:20:55 < tekkkz> does someone of you has keil?
2015-08-21T13:20:55 < mtbg> connect a jumper wire to that LED pin
2015-08-21T13:21:00 < mtbg> connect it to GND also
2015-08-21T13:21:09 < mtbg> if it doesn't light up, connect to 3.3V
2015-08-21T13:21:38 < mtbg> if works, select any pin you like and connect it there
2015-08-21T13:21:58 < mtbg> and modify your code according to the polarity of LED drive
2015-08-21T13:23:02 < karlp> PeterM: I vote for r2com option 4 as well, with a good helping of option 5.
2015-08-21T13:23:04 < tekkkz> it doesnt light up. only if i conenft my multimeter with diode-test mode directly to the led
2015-08-21T13:24:22  * [7] has some weird behavior with the STM32F030's RTC
2015-08-21T13:24:22 < [7]> the DR/TR registers are always zero, only SSR seems to be counting, if BYPSHAD=0
2015-08-21T13:24:22 < [7]> ideas what might cause that?
2015-08-21T13:24:22 < [7]> hm, or not always zero, rather stuck
2015-08-21T13:24:23 < [7]> as soon as I set bypshad=0, the DR/TR regs don't update anymore
2015-08-21T13:24:55 < tekkkz> ahh so the LED and GND must be connected cause the LED pin is the ground pin of the led
2015-08-21T13:25:03 < mtbg> tekkkz: so maybe the other end is connected to some pin instead of supply rail and that LED pin is just to disconnect the LED from that pin
2015-08-21T13:25:06 < tekkkz> but what is the high pin?? maybe someone of the µC
2015-08-21T13:25:09 < mtbg> yep, it seems so
2015-08-21T13:25:19 < mtbg> check with buzzer
2015-08-21T13:25:29 < mtbg> it doesnt take that long
2015-08-21T13:25:37 < tekkkz> buzzer?
2015-08-21T13:25:43 < [7]> despite RSF getting set... even if I clear it, it comes back after a few RTCCLK cycles, as expected
2015-08-21T13:25:47 < mtbg> buzzer setting on your multimeter
2015-08-21T13:26:03 < mtbg> that buzzes when probes are shorted
2015-08-21T13:27:16 < tekkkz> yeah
2015-08-21T13:27:22 < tekkkz> i cant find the connection
2015-08-21T13:27:29 < tekkkz> it doesnt buzzer on any of the µC pins
2015-08-21T13:27:36 < tekkkz> maybe there is a resistor between?
2015-08-21T13:27:45 < mtbg> one probe to to R9 top terminal
2015-08-21T13:28:01 < mtbg> the other slide on microcontroller pins
2015-08-21T13:28:04 < mtbg> with power off
2015-08-21T13:28:27 < karlp> tekkz has gotta be trollin
2015-08-21T13:28:52 < tekkkz> what do you mean=
2015-08-21T13:28:53 < tekkkz> ?
2015-08-21T13:28:58 < tekkkz> mtbg, and karlp
2015-08-21T13:29:16 < mtbg> R9 is your D2 resistor
2015-08-21T13:29:36 < tekkkz> ya
2015-08-21T13:29:38 < tekkkz> correct
2015-08-21T13:29:41 < mtbg> top terminal is connected to led anode as I can tell from the photo
2015-08-21T13:30:03 < tekkkz> i got the pin!!
2015-08-21T13:30:15 < mtbg> congratulations
2015-08-21T13:30:19 < mtbg> you won a balloon
2015-08-21T13:30:27 < tekkkz> r9 is connected to the left side of the µC
2015-08-21T13:30:34 < tekkkz> now i need to find out which pin it is :D
2015-08-21T13:30:35 < karlp> tekkkz: is your led actually on PC13?
2015-08-21T13:31:02 < karlp> (also, I suspec you will _need_ to have the green jumper connected on that badly labelled header to get the led to work)
2015-08-21T13:31:03 < tekkkz> let me check the datasheet of the chip to say this
2015-08-21T13:31:08 < tekkkz> ya
2015-08-21T13:31:17 < tekkkz> , the jumper must be connected
2015-08-21T13:31:18 < karlp> so stop trying to use d2 then...
2015-08-21T13:31:24 < tekkkz> ya
2015-08-21T13:31:33 < tekkkz> but it was in there datasheet so they trolled me ölol
2015-08-21T13:32:40 < Laurenceb> https://www.youtube.com/watch?feature=player_embedded&v=7qWMIKVmd6w
2015-08-21T13:32:44 < tekkkz> btw how did you know karlp that it is c13?
2015-08-21T13:33:52 < Laurenceb> wtf
2015-08-21T13:33:54 < Laurenceb> http://www.gofundme.com/yy7yz3k
2015-08-21T13:33:55 < karlp> because I have another board made byt he same morons that made your board.
2015-08-21T13:34:08 < karlp> also, pc13 is the arduino "led" pin, so it's a good bet
2015-08-21T13:34:22 < karlp> but that jumper _must_ be connected.
2015-08-21T13:34:51 < karlp> it's sort of like one side of that jumper goes to the stm32, and the other to the led, so you can use pc13 for yourself if you want, or leave the jumper in and have it connected to the led
2015-08-21T13:35:20 < karlp> but the boards make no sense, the boot0/1 pins are on a jumper block, but you can't actually put jumpers on them to do anything useful.
2015-08-21T13:35:34 < mtbg> Laurenceb: they will be surprised their very low thermal expansion coefficient cavity gives less thrust than others :>
2015-08-21T13:35:37 < karlp> and fuck knows why jp5 is a latching switch.
2015-08-21T13:36:50 < tekkkz> karlp, yeah, but how do you know from who the board is? now it works all, im very happy with this board now(but not with their schematics :D) just one question left: the jumper at the usb connector(not the white big button, i mean the green one) is it for boot?
2015-08-21T13:43:57 < karlp> I haven't done much with mine yet (mine's similar, but not the same as yours) but it seems to be a raw jumper on the vbus line.
2015-08-21T13:44:25 < mtbg> Laurenceb: that russian can has holes like a cheese grater, hot air rises up trough them and propells the device :>

2015-08-21T13:48:53 < karlp> tekkkz: those yellow shrouded headers, I've only seen them on what turns out to be really shitty boards.
2015-08-21T13:49:48 < karlp> and there's a lot of variants on them, it seems like someone in china learnt how to make a dev board by making 20 iterations of shit ones, but making 100000 of each iteration and flogging them off real cheap on aliexpress
2015-08-21T13:51:08 < [7]> hm...
2015-08-21T13:51:21 < Ecco> it's actually a smart (albeit not very correct) idea :-D
2015-08-21T13:51:29 < [7]> reading RTC_SSR seems to freeze RTC_TR until reset
2015-08-21T13:51:34 < [7]> unless BYPSHAD=1
2015-08-21T13:51:37 < [7]> what the hell...
2015-08-21T13:52:42 < mtbg> https://www.youtube.com/watch?v=A4dVTuE6X6g
2015-08-21T13:53:09 < karlp> Ecco: also, the only reason boards that like survive is because ST _doesn't_ make a cheap board (with USB!) for the f1 series.
2015-08-21T13:53:24 < karlp> there's a cheap disco or nucleo board covering everything else.
2015-08-21T13:53:41 < Ecco> Oh, I didn't know that :-)
2015-08-21T13:53:58 < Ecco> Altium question : I have mechanical constraints that I'd like to import from Solidworks
2015-08-21T13:54:07 < Ecco> for the PCB shape, that's easy
2015-08-21T13:54:35 < Ecco> But I'd like to position some components (keys…) according to what I've planned in solidworks
2015-08-21T13:54:39 < Ecco> How am I supposed to to that?
2015-08-21T13:54:54 < karlp> call your tools vendor and ask for support, that's what you're paying for.
2015-08-21T13:55:02 < Ecco> Yeah, but which one? :-D
2015-08-21T13:55:33 < mtbg> both, on conference call
2015-08-21T13:55:40 < Ecco> hmm
2015-08-21T13:55:49 < karlp> altium of course,
2015-08-21T13:55:54 < karlp> that's where you want the constraints to be

2015-08-21T14:58:44 < mtbg> I placed a vacuum tube in electric furnance trying to minimize thermal gradient inside
2015-08-21T14:59:21 < mtbg> and there was some output with cathode becoming mode positive than rest of electrodes
2015-08-21T14:59:40 < Laurenceb> interesting
2015-08-21T14:59:50 < Laurenceb> but it could be seebek effects
2015-08-21T14:59:54 < Laurenceb> however you spell it
2015-08-21T14:59:54 < mtbg> but I don't think it is a proper test
2015-08-21T15:00:43 < mtbg> the polarity was consistent with this paper
2015-08-21T15:00:58 < mtbg> internal resistance was some dozens MΩ
2015-08-21T15:01:50 < mtbg> can be due some ionic effects in residual gas, or in tube glass itself
2015-08-21T15:02:48 < mtbg> I planned to make a stack with plates covered with cesium oxide on one side and place it in vacuum
2015-08-21T15:03:26 < mtbg> but cesium oxide is quite difficult to make and preserve through evacuation, it will absorb water and CO2
2015-08-21T15:10:55 < mtbg> I think everything would have to be done in some inert and very dry gas, starting from Cs2O synthesis and ending on evacuation
2015-08-21T15:14:20 < mtbg> or, maybe covering the plates with hydroxide or carbonate and then annealing them would be a better way

2015-08-21T15:17:13 < karlp> you can do weird things like use it to create gaps when you're dealing with multiple files.
2015-08-21T15:17:22 < karlp> it's kinda non-obvious when you only have one file.
2015-08-21T15:17:32 < dongs> oh, y ou can have sevearl -i things?
2015-08-21T15:17:36 < karlp> yar.
2015-08-21T15:17:37 < dongs> thats just more insanity i guess.
2015-08-21T15:17:47 < karlp> well, the orders then all matter :)
2015-08-21T15:18:06 < karlp> it lets you take x secondsd from one section of AAA and then y seconds of a section of BBB and make something new.
2015-08-21T15:18:46 < karlp> imagemagick behaves the same way with ordering being important. it's more like a pipeline rather than command arguments but it's hard to put tehm on the command line
2015-08-21T15:18:55 < mtbg> accumulation of skip time is just a side effect, it does different things when done on input than on output
2015-08-21T15:19:09 < dongs> mtbg: its not output skipping time
2015-08-21T15:19:13 < dongs> its still INPUT skipping itme.
2015-08-21T15:19:20 < karlp> gstreamer makes up it's own syntax to be able to express the pipeline thinking, but no-one understands gstreamer syntax, so that failed hard
2015-08-21T15:19:32 < dongs> i wonder how much code in opensores is dedicated to parsing insane command lines
2015-08-21T15:19:37 < mtbg> if done on output it discards output instead of writing
2015-08-21T15:19:39 < dongs> and how much unit testing is done to make sure it all works
2015-08-21T15:19:41 < karlp> not just opensourcs,
2015-08-21T15:19:43 < mtbg> until the given time
2015-08-21T15:19:49 < dongs> mtbg: wrong
2015-08-21T15:19:54 < dongs> after -i its still affecting input file.
2015-08-21T15:20:06 < karlp> massive piles of source do massive piles of grtoss hacks on command lines and arguments

2015-08-21T16:58:01 < dongs> To be honest, I'm sick of getting the updates. I just want my ZANO already. Other manufacturers have come up with all sorts and interesting drones and mini drones.
2015-08-21T16:58:16 < dongs> i hope the next video will a raw footage shoot with the zano in 1080p :)

2015-08-21T16:58:32 < dongs> 1080p @ 1fps maybe
2015-08-21T16:58:44 < mtbg> why didn't hey use some system-on-module computer
2015-08-21T16:58:53 < dongs> because pic32 asm is great
2015-08-21T16:58:54 < mtbg> like these gumstix omap-based
2015-08-21T16:59:21 < mtbg> it has a parallel camera interface, some even have mipi csi
2015-08-21T16:59:27 < dongs> mtbg: because then it would actually be legit
2015-08-21T16:59:36 < dongs> but then it would last even less than 5 minutes on a battery
2015-08-21T16:59:58 < BrainDamage> that doesn't have gigantic profit margins scamming on people's money
2015-08-21T17:00:09 < mtbg> how much current do the motors consume?
2015-08-21T17:00:13 < dongs> amps.
2015-08-21T17:01:25 < mtbg> so the current consumption of control unit will be insignificant, regardless if it is pic32 or some system-on-module
2015-08-21T17:01:34 < Laurenceb> they could have used ambarella
2015-08-21T17:01:42 < dongs> they could have used anything other than pic32

2015-08-21T17:05:29 < dongs> mipi-dsi
2015-08-21T17:05:39 < Laurenceb> oh and you can convert to hdmi?
2015-08-21T17:05:41 < dongs> sure
2015-08-21T17:05:51 < zyp> Laurenceb, it can do 720p30 DSI
2015-08-21T17:05:55 < Laurenceb> ok
2015-08-21T17:06:05 < dongs> i guess its best use would be dsi>lvds for cheap panels

2015-08-21T17:52:15 < emeb> that's cheating.
2015-08-21T17:53:23 < dongs> We have found a few companies who can make the propellers to the quality we expect and we are working on some pretty cool simulations and models of new propellers. The difference is you will be able to buy propellers specific to your purpose. Long flight time hovering propeller for selfies for example and extreme sports propellers designed for maximum speed and agility.
2015-08-21T17:53:28 < dongs> haha
2015-08-21T17:53:37 < dongs> 33% longer flight time with magical torquing group propellers
2015-08-21T17:53:50 < Laurenceb> propeller DRM
2015-08-21T17:54:13 < dongs> So though our flight time statement has been reduce, we are still working hard to resolve that issue. Partly through lighter plastics but largely through propeller design. We have already source the most efficient motor we could find at about 4 times the price of similar but cheaper versions so the rest of the work for us is propellers. Stay tuned on this front and give us time to hit every single performance and functionality improvement we can squeeze out of the ti
2015-08-21T17:54:25 < dongs> they paid 4x to some chink motor reseller

2015-08-21T17:54:48 < Laurenceb> how long can it fly atm?
2015-08-21T17:54:58 < dongs> they derated it to "5-10minutes"
2015-08-21T17:55:07 < dongs> but there hsnt been a single video of it flying from start to end, of course
2015-08-21T17:55:15 < Laurenceb> well the motors need to be well matched to the props
2015-08-21T17:55:24 < dongs> they're using hubsan props
2015-08-21T17:58:34 < upgrdman_> does mabuchi makes uber small motors?

2015-08-21T17:59:08 < dongs> The reason to keep Zano powered in sleep is only for GPS. The GPS looses its current position when it looses power. We looked at adding a back up battery for the GPS memory but honestly I think you can all see there is absolutely no space for one. All the other configuration is stored locally in flash. Restoring the GPS data is more difficult but also something I am looking to add in v1.1 or v1.2 so this problem is resolved to my satisfaction.
2015-08-21T17:59:45 < dongs> .. thats why you have a smartphone WITH gps, and readily downloadable agps data, amirite?
2015-08-21T18:00:07 < dongs> As such, to change the battery without loosing GPS data, you plug Zano in on USB, take out the battery and plug in the new battery. Presto no loss of GPS. Loosing GPS means it can take 1 minute or more depending on cloud cover and location to get a good GPS lock again.
2015-08-21T18:00:11 < dongs> wait wat
2015-08-21T18:00:15 < dongs> zano is always on when battery is plugged in
2015-08-21T18:00:20 < dongs> draining it at like 20mA
2015-08-21T18:00:27 < dongs> thre's no power switch

2015-08-21T18:02:36 < Laurenceb> cant they sleep mode?
2015-08-21T18:02:49 < dongs> Also Zano uses a non standard file system to allow for much faster retrieval of cache data. The reason why is that Zano also uses the SD card as a simple expansion to its on board flash so everything including black box logs are stored on the card. The implementation of a standard file system actually slows the maximum write speed down when Zano is trying to do lots of small updates as well as video as normally the FAT (file allocation table) would require updating t

2015-08-21T18:05:44 < Laurenceb> what do you bet its just using the card as simple addressed memory
2015-08-21T18:05:45 < upgrdman_> is there any reason to use a char instead of a bool, if you just need true/false?
2015-08-21T18:05:54 < upgrdman_> seems these fuckers dont know what a bool is
2015-08-21T18:06:33 < mtbg> bool must be addressable in C
2015-08-21T18:06:56 < mtbg> so it is usually 1 byte anyway
2015-08-21T18:07:06 < upgrdman_> sure
2015-08-21T18:07:13 < upgrdman_> but i mean from a semantic point of view
2015-08-21T18:07:16 < dongs> Laurenceb: addressed wat, pic has no sdio,  so hes not doing anything smart. just writing raw blocks to card
2015-08-21T18:07:19 < zyp> upgrdman_, C didn't have bool until C99
2015-08-21T18:07:41 < dongs> so he doesnt have to update fatfs for each mjpeg frame
2015-08-21T18:07:43 < upgrdman_> zyp, so you mean for 16 years there has been no excuse? ;)
2015-08-21T18:07:52 < zyp> yes
2015-08-21T18:08:01 < zyp> not everybody gets with the times, you know
2015-08-21T18:08:03 < dongs> doesnt stdbool.h just typedef bool to char
2015-08-21T18:08:20 < zyp> yes, and stdbool is a C99 thing
2015-08-21T18:08:22 < upgrdman_> syntactical sugar. but it's so good.
2015-08-21T18:11:07 < jpa-> some people still code C like it is 1989
2015-08-21T18:11:13 < jpa-> because "maybe it will break if i don't"

2015-08-21T18:12:03 < upgrdman_> ya. for some gay reason, lpcexpresso doesn't even do C99 unless you poke one of it's settings.

2015-08-21T18:13:30 < dongs> Imagine your skiing down hill (assuming your not so fast Zano can't keep up). Zano could continuously fly around you whilst always keeping the camera pointing at you. Filming you from every angle.
2015-08-21T18:13:49 < upgrdman_> are there any monitor >4K other than apples gay 5K imac?
2015-08-21T18:13:50 < dongs> yeah, let's fucking see you actually demonstrate this
2015-08-21T18:13:53 < Ecco> As opposed to "skiing uphill"? I'd like to see that :)

2015-08-21T18:14:42 < Ecco> I wouldn't mind being gifted one anyway :)
2015-08-21T18:14:44 < dongs> it is gay, because it runs macos.
2015-08-21T18:14:47 < upgrdman_> Ecco, im just trolling. i own a fagbook pro. tempted to buy the 5k ifag.
2015-08-21T18:14:51 < Ecco> :-D

2015-08-21T18:15:54 < dongs> 'cell'?
2015-08-21T18:15:58 < Ecco> Namely, I think there are two options : using either one or two cells
2015-08-21T18:15:59 < upgrdman_> many CR2032's in parallel?
2015-08-21T18:16:07 < Laurenceb> attn dongs  http://pastebin.com/TxtgPgtx

2015-08-21T18:16:19 < upgrdman_> is lcd backlit?
2015-08-21T18:16:20 < Ecco> So using 2 cells, a LDO regulator should do the trick, right?
2015-08-21T18:16:24 < Laurenceb> recipe for success
2015-08-21T18:16:25 < Ecco> no, LCD is not backlit
2015-08-21T18:16:31 < upgrdman_> most coin cells get pissed if you want more than a dozen mA or so

2015-08-21T20:20:35 < Ecco> I guess I would have to look at the datasheet to tell
2015-08-21T20:20:52 < upgrdman_> http://www.harborfreight.com/cr2032-lithium-button-cell-batteries-4-pk-68129.html
2015-08-21T20:20:59 < upgrdman_> $0.75 each if you buy 4 cells
2015-08-21T20:21:20 < upgrdman_> so prolly < $0.25 if you source them for ali and buy 1k+
2015-08-21T20:21:20 < Ecco> Amazon has some at €3.28 for 5
2015-08-21T20:21:28 < Ecco> including premium shipping
2015-08-21T20:21:39 < Ecco> THanks :)
2015-08-21T20:23:49 < Ecco> … apparently Farnell only has 5 CR2032 holders, the cheapest one being like $2
2015-08-21T20:24:02 < Ecco> Where can I find cheap-ass, super simple ones?
2015-08-21T20:24:07 < upgrdman_> ebay, ali
2015-08-21T20:24:11 < upgrdman_> maybe dx
2015-08-21T20:24:13 < Ecco> Kinda like the one used here: https://cdn.sparkfun.com//assets/parts/6/9/5/1/11285-04.jpg
2015-08-21T20:24:33 < upgrdman_> ya i have some of those that i bought from mouser
2015-08-21T20:24:42 < Ecco> mouser, nice
2015-08-21T20:25:02 < Ecco> Great
2015-08-21T20:25:08 < Ecco> Yeah, perfect
2015-08-21T20:25:09 < upgrdman_> http://www.mouser.com/ProductDetail/Linx-Technologies/BAT-HLD-001/?qs=sGAEpiMZZMtz8P%2feuiupSRWPoTl3m4cbQyLs9uuV7KM%3d
2015-08-21T20:25:10 < Ecco> thanks upgrdman_
2015-08-21T20:25:13 < upgrdman_> $0.20 if you buy 1k
2015-08-21T20:25:21 < Ecco> Excellent
2015-08-21T20:26:09 < upgrdman_> have not used them yet, so im just pointing them out, not rec'ing them
2015-08-21T20:26:25 < Ecco> allright :)
2015-08-21T20:26:53 < Ecco> well it's got a decent datasheet
2015-08-21T20:27:14 < Ecco> Seems good enough

2015-08-21T20:28:16 < Ecco> Now, another trick question: I'd like to find the cheapest way to connect an STM32 to a mobile phone, with a wire. What kind of connectivity would you recommend?
2015-08-21T20:28:44 < Ecco> So far I'm thinking about a 3.5mm jack because the audio port is the only thing that is really cross-platform (regarding mobile phones)
2015-08-21T20:29:03 < Ecco> But on the STM32 side of things the 3.5mm plug is a bit bulky
2015-08-21T20:29:19 < upgrdman_> not sure
2015-08-21T20:29:31 < upgrdman_> to a specific phone, or versatile?
2015-08-21T20:29:41 < upgrdman_> 'cause some phones expose uart via headphone jack
2015-08-21T20:29:45 < upgrdman_> e.g. nexus 4
2015-08-21T20:29:58 < Ecco> Oh I didn't know that
2015-08-21T20:30:05 < Ecco> Oh I think to remember something along those lines
2015-08-21T20:30:09 < upgrdman_> but its NOT a standard thing
2015-08-21T20:30:12 < Ecco> you have to put a resistor on the jack right?
2015-08-21T20:30:25 < upgrdman_> google nexus 4 uart. too lazy to find my bookmark
2015-08-21T20:30:25 < Ecco> And at some point the linux kernel will detect that and map an UART on the jack output right?
2015-08-21T20:30:31 < Ecco> ok :)
2015-08-21T20:30:41 < Ecco> Anyway, no, I want something that works with every phone out there
2015-08-21T20:30:50 < Ecco> So yeah, i'd have to fake an audio signal
2015-08-21T20:30:53 < upgrdman_> so audio is your best bet
2015-08-21T20:30:57 < Ecco> Indeed
2015-08-21T20:31:07 < Ecco> I was actually wondering about hardware connectivity
2015-08-21T20:31:14 < Ecco> 3.5mm jack is just 2 lines + ground
2015-08-21T20:31:20 < Ecco> the jack is an option
2015-08-21T20:31:24 < Ecco> but I guess there are many others
2015-08-21T20:31:35 < upgrdman_> mmm oh you could do bluetooth spp if you only want to target android
2015-08-21T20:31:45 < upgrdman_> then you get a wireless uart to the phone via bluetooth
2015-08-21T20:32:00 < Ecco> Yes, that would be a good suggestion but I need something that works without bluetooth
2015-08-21T20:32:03 < upgrdman_> apple shit wont allow that
2015-08-21T20:32:03 < Ecco> (nor wifi)
2015-08-21T20:32:06 < Ecco> indeed
2015-08-21T20:32:10 < upgrdman_> k

2015-08-21T21:31:34 < qyx_> it won't be that easy I suppose
2015-08-21T21:31:40 < Ecco> why not?
2015-08-21T21:31:48 < Ecco> ARM-A and ARM-M are actually pretty close
2015-08-21T21:32:19 < qyx_> at least there would be no newlib and all cortex-ready stuff
2015-08-21T21:32:37 < Ecco> true
2015-08-21T21:33:07 < Ecco> I'm currently building stuff for an STM32 using OSX's clang
2015-08-21T21:33:34 < Ecco> So I guess it shouldn't be too hard to get something in your case :)
2015-08-21T21:33:47 < Ecco> out of curiosity: what's the point though
2015-08-21T21:33:52 < Ecco> Not that I don't like ARM devices
2015-08-21T21:33:54 < Ecco> but they're slow
2015-08-21T21:34:09 < Ecco> I'd like to avoid compiling on one of those as much as possible

2015-08-21T21:40:22 < qyx_> as a lightweight always-on desktop
2015-08-21T21:42:46 < Ecco> ok :)
2015-08-21T21:43:31 < mtbg> you can build arm-none-eabi with crossdev in gentoo chroot
2015-08-21T21:43:45 < boB_K7IQ> Ecco, what do you prefer over ARM for embedded projects that might be faster ?
2015-08-21T21:44:19 < boB_K7IQ> Especially Cortec M-3 or higher ?
2015-08-21T21:44:43 < boB_K7IQ> For the clock speed that is...

2015-08-21T21:45:24 < boB_K7IQ> I am amazed at how fast our old LPC2366  parts seem to run and what they can do for a 72 MHz part
2015-08-21T21:45:37 < boB_K7IQ> Not even a Cortex anything
2015-08-21T21:45:47 < Ecco> boB_K7IQ: Nothing
2015-08-21T21:46:07 < boB_K7IQ> Oh.  OK.  I was getting the idea that you knew of something faster maybe
2015-08-21T21:46:23 < Ecco> But for a *desktop* I sure prefer a Core i7 or Xeon over an ARM, anytime
2015-08-21T21:46:32 < boB_K7IQ> cuz you said "but they're slow"   maybe you were talking about something entirely different
2015-08-21T21:46:45 < boB_K7IQ> Oh, of course for a desktop !  I agree
2015-08-21T21:46:48 < boB_K7IQ> Nevermind
2015-08-21T21:46:50 < Ecco> :-)
2015-08-21T21:47:02 < boB_K7IQ> I came in late to the conversation
2015-08-21T21:47:05 < Ecco> :)
2015-08-21T21:47:29 < Ecco> For embedded now, it's a completely different question. Unless you want to build a portable oven, in which case an i7 might not be a bad choice.
2015-08-21T21:47:48 < boB_K7IQ> Yeah..   I use an i7 here.
2015-08-21T21:48:00 < boB_K7IQ> But it doesn't have the nice peripherals that I need anyway
2015-08-21T21:48:02 < Ecco> Jokes aside, you should.
2015-08-21T21:48:15 < boB_K7IQ> and probably draws too much power anyway for a "controller"
2015-08-21T21:48:33 < boB_K7IQ> I have wondered though how they might work.
2015-08-21T21:49:58 < boB_K7IQ> My much faster clock Beaglebone won't even display a Youtube video properly
2015-08-21T21:50:13 < boB_K7IQ> faster than 72 MHz I mean
2015-08-21T21:50:30 < boB_K7IQ> but not all that much slower clock speed than my PC
2015-08-21T21:50:51 < boB_K7IQ> 2 or 3 times slower is all.  I was surprised that it couldn't' keep up

2015-08-21T21:54:51 < Ecco> well
2015-08-21T21:54:56 < Ecco> the '90s are over
2015-08-21T21:55:05 < Ecco> clock speed doesn't mean anything anymore
2015-08-21T21:55:26 < Ecco> You should be able to find some real benchmark around
2015-08-21T21:56:00 < Ecco> but I wouldn't be surprised if there were a 10x factor on average between what you get on a recent i7 and a Cortex A7 at the same clock
2015-08-21T21:56:11 < Ecco> Maybe even more actually
2015-08-21T21:57:55 < qyx_> core i3 @ 1.33GHz is about 4x faster than this 1.7GHz cortex
2015-08-21T21:58:13 < qyx_> single core
2015-08-21T21:58:39 < Yoduza> cortex have cache like intel ?
2015-08-21T21:59:04 < boB_K7IQ> very very little !

2015-08-22T00:22:53 < kakimir> reprogram diesel system to inject just pilot injection
2015-08-22T00:23:35 < Laurenceb__> yeah
2015-08-22T00:23:39 < kakimir> and add controlled mass flow of CNG to air inlets after turbo
2015-08-22T00:23:44 < Laurenceb__> yup
2015-08-22T00:24:19 < Laurenceb__> much cheaper than diesel to run, at least in the UK

2015-08-22T02:25:35 -!- Viper168 [~Viper@unaffiliated/viper168] has quit [Ping timeout: 246 seconds]
2015-08-22T02:25:49 < __rob> its strange, I am measuring a pulse that is 37.0208us long, and was expecting over time that a number of samples would converge on the correct value
2015-08-22T02:26:17 < __rob> so averaging the samples.. but no matter how long i sample for, it seems to be larger
2015-08-22T02:26:28 < zyp> what do you mean by accurate?
2015-08-22T02:27:05 < __rob> well, if so if I capture samples and average then the value I get is something like 1777.534 or something
2015-08-22T02:27:47 < zyp> you're doing input capture?
2015-08-22T02:27:51 < __rob> so if I output a pwm with the period being 1777, and every 10 cycles I add 5, every 100 3, every 1000 4 then the pulse is not correct
2015-08-22T02:27:53 < __rob> it drifts
2015-08-22T02:28:05 < __rob> however if I manually tune that floating point value, its more like 1777.123
2015-08-22T02:28:12 < __rob> then I get a pulse with lower drift
2015-08-22T02:28:24 < __rob> with respect to the original 'capture' pulse, if that makes sense
2015-08-22T02:29:02 < __rob> what I am wondering if is if there are factors about the capture on this kind of time scale that I am not taking into account
2015-08-22T02:29:06 < zyp> I'm confused
2015-08-22T02:29:51 < __rob> right, well assume I want to capture a signal, and measure its freqency, then just output the same freqency with another timer
2015-08-22T02:30:34 < zyp> and you need accuracy greater than the timebase interval, so you're trying to do some sort of dithering?
2015-08-22T02:30:38 < __rob> yea
2015-08-22T02:30:45 -!- Abhishek__ [uid26899@gateway/web/irccloud.com/x-faqjrffsqbhmwugi] has quit [Quit: Connection closed for inactivity]
2015-08-22T02:30:45 < __rob> that works fine
2015-08-22T02:31:03 < __rob> I can get a stable pulse for a really decent period
2015-08-22T02:31:19 < __rob> my problem is with the sampling of the original pulse, I take say 10000 samples, and average them
2015-08-22T02:31:34 < __rob> so 1777, 1777, 1778,1777,1777 ...
2015-08-22T02:32:29 < __rob> but the averaged value is always higher. At this specific freqency, its always around 0.5 higher than if I manually tune the dithering myself, by hand with the scope
2015-08-22T02:32:46 < __rob> just by trial and error
2015-08-22T02:33:03 < __rob> and I am wondering why this might be, I've tried very long sample periods
2015-08-22T02:33:03 < zyp> how are you doing the measurement?
2015-08-22T02:33:11 < __rob> tim1 capture
2015-08-22T02:33:25 < __rob> rising edge on the CH1
2015-08-22T02:33:28 < zyp> are you interested in frequency as in cycle time? does low/high amounts matter?
2015-08-22T02:34:02 < __rob> not interested in duty cycle, so I am not using CH2 for that
2015-08-22T02:34:23 < __rob> just interested in rising edge to rising edge time
2015-08-22T02:34:35 < zyp> yeah, okay
2015-08-22T02:34:41 < zyp> how do you have the timer set up?
2015-08-22T02:35:04 < zyp> free-running?
2015-08-22T02:35:18 < zyp> and then you just subtract the difference between subsequent samples?
2015-08-22T02:35:22 < zyp> or are you doing any resetting?
2015-08-22T02:35:32 < __rob> its triggered on the rising edge, and reset on the next by the peripheral
2015-08-22T02:35:41 < __rob> so I just read the CH1 saved value
2015-08-22T02:35:51 < zyp> the next what? edge?
2015-08-22T02:35:58 < __rob> yes,
2015-08-22T02:36:09 < __rob> the next rising edge captures and resets
2015-08-22T02:36:18 < zyp> oh, right
2015-08-22T02:36:35 < zyp> have you tried free running?
2015-08-22T02:37:03 < __rob> I haven't yet
2015-08-22T02:37:14 < zyp> not that I imagine that would make any difference
2015-08-22T02:37:37 < zyp> how does the clock setup look? timer clocked from sysclk, from pll from hse?
2015-08-22T02:37:37 < __rob> well I assumed the reset and capture would all be done within 1 clock cycle
2015-08-22T02:37:57 < __rob> PLL from hse, its a poor oscillator
2015-08-22T02:38:12 < __rob> but, the fact that I can manually tune the dither suggests its not the oscillator
2015-08-22T02:38:52 < __rob> as once i have it tuned, it doesn't drift much at all
2015-08-22T02:38:59 < __rob> I have a video actually.. hang on
2015-08-22T02:40:52 < __rob> processing.. :/
2015-08-22T02:41:03 < __rob> http://sendvid.com/agk547nd
2015-08-22T02:41:29 < __rob> thats a few minutes of tuning. With the measured values it will shift apart in maybe 20 seconds
2015-08-22T02:42:14 < __rob> any ideas? scratching my head a bit..
2015-08-22T02:42:27 < zyp> hmm, you say always around 0.5
2015-08-22T02:42:36 < __rob> well thats on this signal, yeah
2015-08-22T02:42:45 < __rob> not sure if thats constant or proportional
2015-08-22T02:42:57 < zyp> I wonder if there's some uneven rounding or something happening
2015-08-22T02:43:35 < zyp> but I don't know
2015-08-22T02:43:37 < __rob> yea, I think I tried -0.5
2015-08-22T02:43:51 < zyp> maybe reset isn't synchronous with sample
2015-08-22T02:44:04 < __rob> yea, I'll try you idea of free running
2015-08-22T02:44:21 < __rob> although it does seem pretty broken if that fixed the problem
2015-08-22T02:44:29 < __rob> fixes*
2015-08-22T02:44:57 < zyp> I don't know, I've never done anything that needs greater precision than the timer base clock :)
2015-08-22T02:45:22 < zyp> maybe ask Laurenceb, he like doing that sort of weird stuff
2015-08-22T02:46:28 < __rob> well the other option is just do it in an fpga
2015-08-22T02:47:05 < __rob> bit of a shame though as the hard perhipherals I would have though would be just as good
2015-08-22T02:48:35 < __rob> so much stuff of precision motor control etc from stm, I am sure its fixable..

2015-08-22T06:02:36 < muxr> looks pretty good, if you didn't tell me I would be certain it was a sharp prime, I haven't done photography in a few months so I get desentisized to sharp images I guess.. with being innondated with smartphone pics everywhere
2015-08-22T06:03:18 < upgrdman> googled. i used this:  Canon 2562A002 EF 28-135mm f/3.5-5.6 IS USM

2015-08-22T06:12:14 < upgrdman> no problems, but i also havnt done anything special with them
2015-08-22T06:12:22 < emeb_mac> those are fun
2015-08-22T06:12:34 < muxr> how do you like them?
2015-08-22T06:12:38 < emeb_mac> I got 20x a while back. used em for a few projects.
2015-08-22T06:12:51 < upgrdman> emeb_mac, exactly. same here
2015-08-22T06:12:57 < emeb_mac> pretty good performance - 48MHz
2015-08-22T06:13:05 < upgrdman> "need a 555? fuck it. mcu is cheaper."
2015-08-22T06:13:10 < emeb_mac> no shit
2015-08-22T06:13:11 < muxr> exactly
2015-08-22T06:13:43 < emeb_mac> did this w/ em: http://ebrombaugh.studionebula.com/embedded/lightshow/index.html
2015-08-22T06:13:49 < upgrdman> i also regularly overclock my f0's to 64MHz with no adverse effects yet
2015-08-22T06:14:44 < muxr> I know that with some F103s you can address more flash than the spec sheet says, I should try it with these
2015-08-22T06:15:43 < muxr> emeb_mac: nice!
2015-08-22T06:17:09 < emeb_mac> also this breakout: http://ebrombaugh.studionebula.com/embedded/stm32f030breakout/index.html
2015-08-22T06:18:05 < emeb_mac> the F042 is a nice variation - a bit more memory and crystal-less USB too.
2015-08-22T06:18:14 < emeb_mac> but like $1 more.
2015-08-22T06:20:01 < muxr> nice, good to know, going with 070 on one project since I know I will need a ton of memory, but for all the other stuff, 030 seems to be perfect, cheap and capable

2015-08-22T06:26:50 < muxr> been meaning to give stm32 a shot for awhile, have only done simple getting my feet wet with it so far
2015-08-22T06:27:00 < emeb_mac> dongs: I've used keil. It's OK.
2015-08-22T06:27:36 < emeb_mac> don't care to shell out $4k for it tho.
2015-08-22T06:27:57 < muxr> which IDE do you prefer ?
2015-08-22T06:28:41 < emeb_mac> I've used various Eclipse-based things (Coocox, Yagarto) and Em::Blocks
2015-08-22T06:29:07 < muxr> I've tried to get the Eclipse one going a month ago but the sourcefourge project for one of the components has been down since SF took a dive. I've been using Coocox instead
2015-08-22T06:29:08 < emeb_mac> hate eclipse. Em::Blocks is OK. A bunch of my clients use it and I support them on it.
2015-08-22T06:29:41 < upgrdman_> emeb_mac, re: synth, where's you get the pots and knobs?
2015-08-22T06:30:09 < emeb_mac> upgrdman_: the pots are BI 9mm parts - get 'em at Digi-Key.
2015-08-22T06:31:52 < emeb_mac> Knobs I got from Grayscale (grayscale.info)
2015-08-22T06:32:07 < emeb_mac> but looks like they're not selling that style now.

2015-08-22T13:58:57 < Tectu> is there such a thing as a recommended value for an external pullup resistor for a GPIO input pin (user button)?
2015-08-22T13:59:08 < Tectu> for years I just wacked in 10k w/o ever really thinking about it
2015-08-22T14:00:40 < __rob> doesn't matter that much does it, your just limiting the current
2015-08-22T14:01:08 < __rob> so it doesn't short to gnd or supply when you push it
2015-08-22T14:01:26 < Tectu> indeed
2015-08-22T14:02:05 < Tectu> well, for open drain based communication stuff like I2C there are recommended values due to frequency crap. But I assume that does not really matter that much for a GPIO pin as you most likekly wont press the button at 400khZ

2015-08-22T14:12:11 < Ecco> because it also says "1.7V to 3.6V application supply". Does that mean that the chip just wastes 2x more power when fed 3.7V?

2015-08-22T15:43:25 < Ecco> So actually
2015-08-22T15:43:38 < Ecco> It would be more efficient to power the STM straight off of the battery?
2015-08-22T15:44:03 < Ecco> (Coin cell ranges from 3.something to 2.0V)
2015-08-22T15:50:23 < karlp> unless you need a fixed voltage for something else, sure, why wouldn't you?
2015-08-22T15:51:55 < Ecco> Well, I do need a "fixed" voltage for the LCD panel
2015-08-22T15:52:06 < Ecco> Actually the datasheet says "between 2.7 and 3.3V"
2015-08-22T15:52:56 < Ecco> I could power the STM straight off the battery and use a regulator only for the LCD though
2015-08-22T15:53:18 < Ecco> but the LCD expects its IO to be "close" to its input voltage
2015-08-22T16:06:57 < Ecco> Ok, I eventually wrapped my mind around this. I'm looking for a boost converter that would take a single CR2032 in (so between 2.0 and 3.0V) and output 3.3V. Expected current is between 1 and 5 mA. What converter would you recommend? Ideally not too expensive and not made by Ti.
2015-08-22T16:07:07 < Ecco> (TPS63001 sure would do the job but it's very expensive)
2015-08-22T16:10:49 < muxr> http://www.mouser.com/ProductDetail/Texas-Instruments/TLV61225DCKR/?qs=sGAEpiMZZMtitjHzVIkrqVtPTmE2vS2PDppcHT7RomY%3d ?
2015-08-22T16:11:48 < Ecco> Hmm, yeah, like this one. I'd like one not made by Ti if possible though.
2015-08-22T16:11:56 < Ecco> Also, why do they ask for an inductance?
2015-08-22T16:12:03 < Ecco> (I mean, an external inductance)
2015-08-22T16:12:11 < Ecco> (in the typical application schematic)
2015-08-22T16:13:10 < muxr> I know microchip has some interesting DC-DC converters, I've used one of their buck converters while back
2015-08-22T16:13:17 < Ecco> Thanks
2015-08-22T16:14:48 < Ecco> Apparently the only cheap alternative to Ti seems to be OnSemi
2015-08-22T16:14:59 < Ecco> Namely, the NCP1400 series
2015-08-22T16:15:11 < muxr> switching regs. often use inductors, to deal with current ripple
2015-08-22T16:15:20 < Ecco> Are those craps like the LM1117
2015-08-22T16:15:31 < Ecco> muxr: I understand. Thanks.
2015-08-22T16:16:07 < muxr> don't have experience with NCP1400 unfortunately
2015-08-22T16:16:09 < Steffann> Why so anti-TI Ecco?
2015-08-22T16:16:17 < Ecco> I'm not anti-ti at all
2015-08-22T16:16:36 < Steffann> it's the second time i see you say "not made by Ti" :P

2015-08-22T16:17:00 < Ecco> Yes
2015-08-22T16:17:20 < Ecco> I'm in touch with a supplier who told me he doesn't manage to get good deals on Ti components
2015-08-22T16:17:46 < Ecco> Maybe he's overstating it though, I don't know
2015-08-22T16:18:15 < Ecco> The dude told me "just send me your BoM once it's ready and I'll get you a good deal. Unless it's packed with Ti components."
2015-08-22T16:18:35 < muxr> I like your original idea as well, no DC-DC converter, dave from eevblog on his calculator watch didn't use one either and for the LCD higher voltage he just used a very basic charge pump, since LCD uses very little current
2015-08-22T16:19:22 < Ecco> Interesting!

2015-08-22T17:37:47 < dongs> and there's a table further on that shows the pinout
2015-08-22T17:38:00 < Ecco> I was looking for the pinout on the cable holder datasheet
2015-08-22T17:38:20 < dongs> i looked at that to make footprint

2015-08-22T17:40:14 < dongs> its a tiny bit diff but its possible to make compatible footprint, i just used it for 3d model
2015-08-22T17:40:25 < Ecco> ok
2015-08-22T17:40:29 < Ecco> Well the footprint is easy to make
2015-08-22T17:40:49 < dongs> what fucking pcb cad requires making models in solidworks
2015-08-22T17:40:55 < Ecco> None
2015-08-22T17:40:59 < dongs> instead of just placing a 3d body or wahtever
2015-08-22T17:40:59 < Ecco> None that I know of at least
2015-08-22T17:41:05 < dongs> then why did you do that
2015-08-22T17:41:08 < Ecco> But how do you generate said 3d body?
2015-08-22T17:41:31 < dongs> altium can place 3d primitives
2015-08-22T17:41:35 < Ecco> Indeed
2015-08-22T17:41:52 < dongs> rectangle/sphere/cylinder
2015-08-22T17:42:19 < Ecco> But I got my workflow worked out for this:

2015-08-22T17:43:18 < dongs> pssh. im sure that shit is on one of free 3d model sites or else keystone or similar manufacturer
2015-08-22T17:43:36 < Ecco> Might be. Couldn't find it though, and it wasn't that long to make.
2015-08-22T17:43:41 < dongs> http://i.imgur.com/OPZepSV.png i did that F connector 3d thing with cylinder+rectangle on footprint
2015-08-22T17:44:07 < Ecco> In all honesty, I don't really need the 3D thing, my package isn't that tight
2015-08-22T17:44:13 < Ecco> It's more of an eyecandy

2015-08-22T18:36:38 < Tectu> Is there a way to use a method of a C++ object in a c callback function pointer? ChibiOS takes a function pointer in a config struct and I need to access some private members of the C++ object which creates the callback configuration struct.
2015-08-22T18:39:48 < Ecco> Tectu: here's the deal: C functions are globals, C++ objects not necessarily
2015-08-22T18:40:08 < Tectu> Ecco, indeed
2015-08-22T18:40:20 < Tectu> I read something about that it would work when the method in the C++ object is static
2015-08-22T18:40:24 < Ecco> So unless you can pass a "void * context" that's going to be passed back to your callback when you register it, you're somewhat fucked
2015-08-22T18:40:24 < Tectu> but couln´t get that working yet
2015-08-22T18:40:38 < Tectu> :/
2015-08-22T18:40:41 < Ecco> Don't know if I was clear though
2015-08-22T18:40:52 < Ecco> register_callback(my_function) -> you're fucked
2015-08-22T18:41:11 < Ecco> register_callback(my_function, context) which later calls my_function(context) -> ok
2015-08-22T18:41:26 < Ecco> In the "you're fucked" case, it just means you have to make your C++ object global
2015-08-22T18:41:44 < Ecco> because there is no such thing as a pointer to a given object's method
2015-08-22T18:42:12 < Ecco> methods are just function that take an object as a parameter
2015-08-22T18:42:54 < Tectu> (A::)(A , int, int*)
2015-08-22T18:42:56 < Tectu> something like that, right?
2015-08-22T18:43:18 < Ecco> well, yeah. The compiler hides it from you though, but that's the idea
2015-08-22T18:43:38 < Ecco> Most libraries take a void
2015-08-22T18:43:41 < Ecco> damn
2015-08-22T18:43:50 < Ecco> Most libraries take a void * context for callback, for this specific reason
2015-08-22T18:43:52 < Tectu> so I am fucked
2015-08-22T18:43:54 < Ecco> Maybe yours does too?
2015-08-22T18:44:03 < Tectu> I have no idea
2015-08-22T18:44:12 < Ecco> Otherwise, that just means you have to create a global object
2015-08-22T18:44:20 < Tectu> http://chibios.sourceforge.net/docs3/hal/struct_g_p_t_config.html
2015-08-22T18:44:34 < Tectu> typedef void(* gptcallback_t) (GPTDriver *gptp)
2015-08-22T18:45:08 < Tectu> Ecco, the object from which I want to call a method in the callback is created during runtime.
2015-08-22T18:45:37 < Tectu> Ecco, so I would need a wrapper object that is global and stuff and pass it a pointer to the created object and then wrap the callbacks throuch there?
2015-08-22T18:47:47 < Ecco> uuuh, I don't know
2015-08-22T18:47:56 < Ecco> ok your callback takes a parameter though
2015-08-22T18:48:04 < Ecco> isn't it possible to put your object in the GPTDriver * ?
2015-08-22T18:48:25 < Ecco> Seems a bit dirty though
2015-08-22T18:48:32 < Ecco> yeah, that callback lacks a context…
2015-08-22T18:48:45 < Steffann> bug report time Tectu :P
2015-08-22T18:48:56 < Ecco> What you'd need is pretty simple at this point
2015-08-22T18:49:03 < Ecco> declare the object you need as global
2015-08-22T18:49:04 < Steffann> or feature request, whatever you want to call it
2015-08-22T18:49:08 < Ecco> and reference it in the callback
2015-08-22T18:49:10 < Ecco> that's about it
2015-08-22T18:49:24 < Ecco> check for NULL in the callback if the object is created dynamically
2015-08-22T18:50:00 < Tectu> Ecco, how do I declare an object as global?
2015-08-22T18:50:16 < Tectu> maybe noob question, who knows
2015-08-22T18:50:25 < Ecco> yeah, definitely noob question :)
2015-08-22T18:50:41 < Ecco> extern MyClass my_object;

2015-08-22T19:38:59 < Ecco> ok :)
2015-08-22T19:39:11 < Ecco> Also, hand soldering SMD : 0805 or 0603?
2015-08-22T19:39:29 < jpa-> 0603 or 0402
2015-08-22T19:39:33 < jpa-> 0805 is just silly big
2015-08-22T19:39:37 < Ecco> 0402? Seriously?
2015-08-22T19:39:44 < Ecco> I'm not on a small PCB
2015-08-22T19:40:00 < Ecco> http://www.hobbyelectronics.net/uploads/6/5/7/2/6572022/8603275.jpg
2015-08-22T19:40:02 < jpa-> if size doesn't matter, sure, 0805 works
2015-08-22T19:40:22 < Ecco> 0603 is the tiny dust speck on the left :-/
2015-08-22T19:40:24 < jpa-> but fitting 0402 filter caps etc. is much nicer
2015-08-22T19:40:52 < Ecco> Keep in mind that I'm not reflowing

2015-08-22T19:42:02 < Ecco> Do you use a microscope when soldering?
2015-08-22T19:42:10 < jpa-> my technique is basically just to tin one pad, put part in place with tweezers, heat the pad so that it gets soldered, then it is easy to solder the other pad
2015-08-22T19:42:18 < Ecco> ok
2015-08-22T19:42:22 < Ecco> Well I never tried it
2015-08-22T19:42:22 < jpa-> nope, but i do use a microscope for verifying
2015-08-22T19:42:25 < Ecco> ok
2015-08-22T19:42:36 < jpa-> i did begin with 0805 though, moved to 0402 later
2015-08-22T19:42:43 < Ecco> ok
2015-08-22T19:42:52 < Ecco> Well, I'll probably stick with 0805 for this PCB
2015-08-22T19:43:01 < Ecco> It's got tons of space since the back is a keypad
2015-08-22T19:43:13 < jpa-> http://essentialscrap.com/doglight/soldered.jpg   for example here on the left you can see how much nicer the 0402 filter caps fit there (for reference, the bigger cap on lower left is 0805)
2015-08-22T19:43:31 < Ecco> Oh thanks
2015-08-22T19:43:51 < Ecco> I see

2015-08-22T19:43:57 < Ecco> Yeah, on such a small PCB that makes sense
2015-08-22T19:44:17 < Ecco> What package size is the STM32? TQFP 64 ?
2015-08-22T19:44:30 < jpa-> tqfp48 i think
2015-08-22T19:44:38 < Ecco> ok
2015-08-22T19:44:58 < jpa-> common parts i buy in bulk (100s or 1000) for cheaper price, to makes sense to only have 0402
2015-08-22T19:45:00 < Ecco> Yeah you're right actually, 0805 don't seem so small when seen on this picture
2015-08-22T19:45:10 < Ecco> That makes sense
2015-08-22T19:45:10 < jpa-> some pcbs i make are small, others are big
2015-08-22T19:45:57 < jpa-> http://essentialscrap.com/eink/pcb.jpg   also helps for having nice tight SMPS layouts like here on the upper right.. supposedly makes the SMPS work better when you minimize the area
2015-08-22T19:46:19 < Ecco> hmm
2015-08-22T19:46:36 < zyp> I think 0402 is slightly annoying, so I'm buying 0603 for bulk stuff
2015-08-22T19:46:59 < Ecco> jpa-: In the image you just linked, C4 and C19 are 0603 ?
2015-08-22T19:47:11 < jpa-> Ecco: no, 0805
2015-08-22T19:47:14 < Ecco> ok :)
2015-08-22T19:47:25 < jpa-> i don't think i own any 0603 parts :P
2015-08-22T19:47:29 < Ecco> allright :)
2015-08-22T19:47:39 < zyp> I've done a 0402 design, I got fed up by tombstones
2015-08-22T19:48:13 < zyp> then again, it was my first design I reflowed, so it's probably as much bad technique as anything
2015-08-22T19:48:26 < jpa-> i tried to hotair a 0603 design once, got fed up by tombstones also.. but that was just my crappy tecnique :)
2015-08-22T19:48:59 < Tectu> I always use 0603
2015-08-22T19:49:06 < Tectu> I don´t have any 0805 components here
2015-08-22T19:49:15 < zyp> I'm planning to go 0402 for the nrf design I'm planning since I want that to be super small
2015-08-22T19:49:41 < Tectu> I had to solder a few 0402 before. Worked out well with one of those 3D vision mantis things. but that is nothing I could afford for home usage
2015-08-22T19:49:43 < jpa-> i wonder if i should try lora in a hobby project also - been playing with it at work and seems pretty cool
2015-08-22T19:49:52 < Tectu> lora?
2015-08-22T19:50:03 < jpa-> semtechs long range radio stuff
2015-08-22T19:50:15 < zyp> but then again, I'm not really planning to assemble that myself, I'll probably just throw some money at dongs for him to run a small series for me
2015-08-22T19:50:16 < Tectu> ah
2015-08-22T19:50:17 < jpa-> some 10-100km range at some 300bps rate
2015-08-22T19:50:33 < Tectu> oh, that sounds interesting
2015-08-22T19:50:40 < Tectu> is that in a ´free band´?
2015-08-22T19:50:46 < zyp> 433?
2015-08-22T19:50:53 < jpa-> yeah, 433 or 868
2015-08-22T19:51:32 < zyp> that reminds me, I bought some 2.4g boards with a transceiver and a PA
2015-08-22T19:51:42 < Steffann> In amsterdam they built a city covering LoRa network for the "IoT" mania.
2015-08-22T19:51:47 < zyp> some time I'm going to try how long range I can get from that
2015-08-22T19:52:21 < Steffann> *are building actually
2015-08-22T19:53:12 < jpa-> Steffann: yeah, lots of public lora networks popping up now - not sure how they'll price them though, maybe it'll be cheaper to just run your own
2015-08-22T19:53:57 < Steffann> it seems to be a "open crowdsourced Internet of Things data network", but im not sure if they mean free with "open"
2015-08-22T19:54:08 < Steffann> it's a semi-commercial network so...
2015-08-22T19:58:19 < jpa-> http://webshop.imst.de/radio-modules/im880a-l-long-range-radio-module.html   hm, 23€; not exactly cheap

2015-08-22T20:44:01 < Ecco> Why? Why not a single Cap ?
2015-08-22T20:44:13 < Ecco> (That's from ST's STM32F429Disco)
2015-08-22T20:49:19 < Tectu> because there are multiple VDD pins and each one must be decoupled on it´s own
2015-08-22T20:49:36 < zyp> yes
2015-08-22T20:49:36 < Tectu> these are placed all next to each other in the schematics but there is always one or two of those next to each VDD pin for decoupling
2015-08-22T20:49:56 < Tectu> also, in theory and in practice one big cap does not act the same as many small ones directly in parallel
2015-08-22T20:50:01 < Tectu> but that is not the reason here
2015-08-22T20:50:13 < zyp> the point of a decoupling cap is to provide a local buffer close to the load

2015-08-22T21:39:02 < Ecco> There are 3 VSS pins and 3 VDD pins
2015-08-22T21:39:18 < Ecco> Why? I mean there aren't that many pins on the package already, why duplicating some?
2015-08-22T21:40:28 < Steffanx> for each port a pair of vss/vdd ?
2015-08-22T21:40:49 < Steffanx> nah not really

2015-08-22T21:52:54 < jpa-> Ecco: because a single pair of pins cannot transport enough current
2015-08-22T21:53:08 < jpa-> (especially at low enough inductance)
2015-08-22T21:53:49 < jpa-> (remember that at the end of the "thick" looking pins, there is a very thin gold wire that connects it to the chip)
2015-08-22T22:01:13 < zyp> I think it's interesting that there's often more vdd pins than gnd pins on stm32
2015-08-22T22:01:44 < englishman> Routing large metal planes is area expensive too
2015-08-22T22:01:47 < zyp> I would have thought that if you were going to have an uneven number, you'd prefer to have more grounds

2015-08-22T22:01:55 < Ecco> But I understand
2015-08-22T22:01:59 < englishman> Larger chips have those bypass ports
2015-08-22T22:02:34 < Ecco> Another question : should I ground unused GPIO pins in my design or leave them unconnected?
2015-08-22T22:02:42 < zyp> leave them
2015-08-22T22:02:56 < Ecco> I would think unconnected in case I goof the firmware up and try to drive them high

2015-08-22T22:03:06 < englishman> This is covered

2015-08-22T22:03:17 < Ecco> Actually I remember reading about it but forgot :)
2015-08-22T22:03:25 < Ecco> I'll re-read the datasheet
2015-08-22T22:04:04 < zyp> if you set unused pins to analog mode, you turn off the digital input block anyway, negating any benefit you'd have from tying the pins anywhere
2015-08-22T22:05:12 < zyp> and by leaving them floating you always have the option to greenwire them later if you need
2015-08-22T22:09:35 < Ecco> greenwire?
2015-08-22T22:09:53 < Ecco> As in "hask the PCB and wire straight on the chip"?
2015-08-22T22:09:56 < Ecco> hack

2015-08-23T01:31:43 < upgrdman_> is it normal having to put a cap on every adc input?

2015-08-23T02:32:17 < upgrdman_> dongs, should apetures be smaller than pad?
2015-08-23T02:32:22 -!- zz_ka6sox is now known as ka6sox
2015-08-23T02:37:44 < dongs> no the pcb place will murder you if you do that
2015-08-23T02:50:52 < PeterM> dongs well, it depends on stencil thickness - if you have very thick stencil but also very dense parts, apeture reduction is nessecary
2015-08-23T02:53:28 < PeterM> also if paste aperture = soldermask opening on ics with large pads like qfn with thermal pad, the outside pins may not sodler correctly because middle pad will "float" it up
2015-08-23T02:57:23 < zyp> dongs, haha, any particular pads that's bad?
2015-08-23T02:58:55 < PeterM> also, on the topic of 0402/0603/0805 0805 = useless for anything apart from caps, 0603 is pretty optimal it is much smaller than 0805 but still easy to place, solder etc and you can route traces under it, 0402 is great for dense designs but you need pcb manufacture and assembly to match, otherwise your pads are almost as big as your component making it not that much of a size improvement over 0603, also you cant route 2 traces under it so y
2015-08-23T02:59:06 < PeterM> either for high value vaps or low value/hgigh power resistors
2015-08-23T02:59:38 < zyp> PeterM, yeah, qfn middle pad should obviously have smaller apertures

2015-08-23T03:01:34 < PeterM> on things like large smd passives you want to reduce aperture size too, beacuse endcaps are only pretty small compared to component and pad size
2015-08-23T03:02:20 < zyp> hmm, I'm not sure I agree
2015-08-23T03:04:05 < zyp> while endcaps are small, remember that apertures only define area
2015-08-23T03:04:56 < PeterM> yes, but also remember the internal side of the pad needs almost 0 solder
2015-08-23T03:06:02 < zyp> remember that for a given shape, volume scales by n^3

2015-08-23T03:43:04 < dongs> is it running windows 10 yet
2015-08-23T03:43:21 < upgrdman_> so stm adc has "1 channel for internal reference voltage" ... is this the voltage used by the adc? if so, wouldn't this be a constant if the adc were to try and measure it?
2015-08-23T03:44:32 < zyp> not if you're running adc off external reference, I guess
2015-08-23T03:44:42 < zyp> but yeah, otherwise it's just a sanity check, I guess

2015-08-23T03:55:38 < emeb_mac> upgrdman_: some stm parts always reference ADC values to external VDDA. Internal bandgap gives a way to calibrate that.
2015-08-23T03:56:10 < upgrdman_> o
2015-08-23T03:56:24 < emeb_mac> since internal bandgap value is stored in system flash - you can back out the measurements to absolute voltage.
2015-08-23T03:56:39 < upgrdman_> neat

2015-08-23T07:21:29 < upgrdman_> even in the rich parts of china, the public bathrooms do NOT have toilet paper. because people would take it. because people can't always afford it.

2015-08-23T09:35:00 < dongs> not sure what the fuck your question is
2015-08-23T09:35:38 < dongs> you could run proper esxi and connect to the vm from anywhere using vmware client thing?
2015-08-23T09:39:30 < PeterM> if you want better performance than vnc can't use just use mstsc/rdp on windows or remote desktop window manager on loonucks?
2015-08-23T09:39:56 < PeterM> but if you want remote vm usage, what dongs says

2015-08-23T09:48:19 < dongs> yeah i connect to my esxi via RDP on a 2008 host thats running on it
2015-08-23T09:48:33 < dongs> and then run vmware client shit inside
2015-08-23T09:48:35 < dongs> to manage other vms.
2015-08-23T09:48:48 < dongs> err 2008 guest
2015-08-23T09:50:08 < PeterM> the local rendering/responsiveness of the gui using rdp/mstsc makes vnc shit
2015-08-23T09:51:05 < dongs> last i used vnc was in like 2001
2015-08-23T09:51:09 < dongs> has it stopped sucking?
2015-08-23T09:51:17 < PeterM> no
2015-08-23T09:51:24 < dongs> i remember it had awful drawing errors
2015-08-23T09:51:33 < dongs> like it would sometimes not update some shit that changed on screen
2015-08-23T09:51:38 < dongs> so you had to mouse over to see new crap
2015-08-23T09:51:56 < PeterM> that depends on the server/client and the compression formats and image quality and compression etc
2015-08-23T09:52:03 < PeterM> its garbage
2015-08-23T09:52:22 < dongs> i dont think tehre was anything besides RLE / lossless compression back then
2015-08-23T09:52:28 < dongs> the jpeg/etc newfag shit was added wayt later
2015-08-23T09:52:30 < dongs> wehn i stopped caring

2015-08-23T11:02:14 < BMWMPower> Hope I can experiment with the STM
2015-08-23T11:02:14 < jpa-> why not just buy a discovery board?
2015-08-23T11:02:48 < jpa-> hopefully you atleast have a schematic for the dev board unlike the guy that was here the other day

2015-08-23T11:04:23 < BMWMPower> I want to try out some chips I always used the PIC18F and 16F and pickit 2
2015-08-23T11:04:58 < dongs> have you ever used pic32mz
2015-08-23T11:05:00 < BMWMPower> I want to learn how to use this
2015-08-23T11:05:13 < BMWMPower> No 18 and 16
2015-08-23T11:05:25 < dongs> BMWMPower: what is your favorite operating system
2015-08-23T11:05:51 < BMWMPower> Made an CAN interface myself with 18F and MCP's
2015-08-23T11:06:47 < BMWMPower> Dongs I love Unix based systems but have to work more with Windows based envis cause companies do
2015-08-23T11:08:12 < BMWMPower> I am busy a lot with Hadoop and database clusters
2015-08-23T11:08:28 < BMWMPower> And software interfaces
2015-08-23T11:09:23 < BMWMPower> I have a cnc for electronics and can make my own "simple" pcbs
2015-08-23T11:09:52 < BMWMPower> But more DIP than SMD :-)
2015-08-23T11:10:06 < BMWMPower> I am oldschool
2015-08-23T11:11:29 < dongs> pro versions of STM32 only come in 0.5mm pitch BGA
2015-08-23T11:11:34 < dongs> nothing in DIP
2015-08-23T11:11:48 < BMWMPower> I know :-)
2015-08-23T11:12:29 < BMWMPower> So i have to make my PCB different in Eagle
2015-08-23T11:19:19 < BMWMPower> I hope I can learn I2C with this chipset and figure out the datasheets

2015-08-23T12:47:12 < Ecco> :-D
2015-08-23T12:47:23 < dongs> Ecco: did you see wat i said about lcd schematic.
2015-08-23T12:47:27 < Ecco> Yes, thanks a lot
2015-08-23T12:47:32 < Ecco> Actually you saved my ass
2015-08-23T12:47:35 < dongs> pfft
2015-08-23T12:47:38 < dongs> because you fucked it up?
2015-08-23T12:47:45 < Ecco> The LCD panel I was considering didn't have SPI in their reference design
2015-08-23T12:47:47 < Ecco> Yes
2015-08-23T12:47:51 < dongs> huhu
2015-08-23T12:47:57 < Ecco> Turns out they don't let us enable SPI on said panel
2015-08-23T12:48:08 < Ecco> (the pin in the controller that enables SPI is not mapped on the FPC)
2015-08-23T12:48:20 < Ecco> So the controller supports SPI, but not the LCD module
2015-08-23T12:48:34 < Ecco> So I actually have another question

2015-08-23T12:49:00 < dongs> hah, no idea :p i reflow
2015-08-23T12:49:04 < Ecco> ok :-)
2015-08-23T12:49:11 < dongs> you mean that cable directly to pcb?
2015-08-23T12:49:12 < dongs> wihtout socket?
2015-08-23T12:49:13 < Ecco> Yes
2015-08-23T12:49:15 < dongs> or the socket for it
2015-08-23T12:49:15 < Ecco> yes
2015-08-23T12:49:22 < Ecco> No, this cable specifically has no socket
2015-08-23T12:49:24 < dongs> i think its doable, iirc the had small vias in one ihad
2015-08-23T12:49:36 < dongs> so you can just align w/pre-tinned pads and heat it up and done
2015-08-23T12:49:48 < Ecco> ok
2015-08-23T12:49:49 < Ecco> Actually
2015-08-23T12:49:53 < Ecco> I do have a panel here

2015-08-23T12:50:04 < dongs> those 0.96 oled things came with that kinda cable
2015-08-23T12:50:09 < Ecco> (so pads match exactly the cable)
2015-08-23T12:50:20 < Ecco> In theory you're supposed to use a dedicated tool called a hot bar
2015-08-23T12:50:24 < Ecco> but that's for volume production

2015-08-23T12:51:24 < Ecco> Some dumbass decided to go with a … 0.9mm pitch

2015-08-23T15:58:19 < owl-v-> hey dongs, can a wrong clock setting disable i2c communication?
2015-08-23T15:58:34 < dongs> i duno it might be slow?
2015-08-23T15:59:25 < dongs> what does it look on scope?
2015-08-23T16:01:17 < Ecco> STM32F4's datasheet says I need a 4.7 uF capacitor.
2015-08-23T16:01:31 < dongs> yes. you do
2015-08-23T16:01:36 < jpa-> owl-v-: errata has something about i2c rate setting IIRC
2015-08-23T16:01:43 < Ecco> Should I go with a multilayer ceramic one?
2015-08-23T16:02:01 < jpa-> yeah
2015-08-23T16:02:05 < Ecco> ok :)
2015-08-23T16:02:21 < Ecco> Wow, they're "expensive" (for passives I mean)
2015-08-23T16:02:33 < Ecco> http://www.mouser.fr/ProductDetail/Murata-Electronics/GRM188R61E475KE11D/?qs=sGAEpiMZZMs0AnBnWHyRQKFZIQ7b73cddMUzkLTawUUI1CSNHoxYvg%3d%3d
2015-08-23T16:02:45 < dongs> i think a reel of 4.7uF 0603 costs me something like 25-30$
2015-08-23T16:03:01 < Ecco> Thing is, some reference designs I've seen seem to indicate polarized caps
2015-08-23T16:03:03 < jpa-> Ecco: why 25V?
2015-08-23T16:03:14 < Ecco> jpa-: Good question
2015-08-23T16:03:22 < Ecco> Actually, I'm using some caps for an LCD
2015-08-23T16:03:35 < Ecco> and some of those are handling higher tensions
2015-08-23T16:03:45 < Ecco> (I don't remember which exactly, but definitely over 10V)
2015-08-23T16:04:04 < Ecco> I'm not sure I made the right choice though
2015-08-23T16:04:07 < Ecco> But here's my reasonning
2015-08-23T16:04:15 < Laurenceb__> http://venturebeat.com/2015/08/19/here-are-the-top-10-programming-languages-used-on-github/
2015-08-23T16:04:16 < Ecco> -> I'm protyping, so saving on passives makes no sense
2015-08-23T16:04:21 < Laurenceb__> lol javascript
2015-08-23T16:04:38 < Ecco> -> I'd like to avoid having too many different components
2015-08-23T16:04:41 < dongs> haha thats fucking awful
2015-08-23T16:04:44 < dongs> why is ruby even in taht list
2015-08-23T16:04:46 < dongs> what the fuck
2015-08-23T16:04:50 < dongs> there's liek 10 ruby users
2015-08-23T16:05:02 < jpa-> Ecco: running out of components sucks also, so getting a bunch of cheap 4.7µF 6.3V caps is not a bad idea
2015-08-23T16:05:10 < Ecco> Indeed
2015-08-23T16:05:14 < Ecco> But why not 25V?

2015-08-23T16:05:59 < Ecco> Yeah, but keep in mind I'll order at most 100
2015-08-23T16:06:03 -!- BMWPower is now known as Guest67101
2015-08-23T16:06:11 < Ecco> and probably a lot less
2015-08-23T16:06:11 < qyx_> yeah, but those 4.7uF 6.4V 0603 caps became more like 1uF a 3.3V
2015-08-23T16:06:20 < Ecco> what?
2015-08-23T16:07:28 < Ecco> Anyway, why do some design use polarized caps instead of MLCC?
2015-08-23T16:12:40 < englishman> too much money
2015-08-23T16:13:17 < englishman> this is proper stm32 decoupling http://i.imgur.com/yAghyax.jpg

2015-08-23T16:17:29 < Ecco> Oh wow
2015-08-23T16:17:33 < owl-v-> line 9 -> http://pastebin.com/ndsyiHxx
2015-08-23T16:18:07 < jpa-> qyx_: 0603 sure, but at 0805 i think 25V caps act pretty much the same as 6.3V
2015-08-23T16:18:35 < Ecco> Hmm
2015-08-23T16:19:22 < dongs> owl-v-: that code tells me you dont have a scope
2015-08-23T16:21:00 < owl-v-> nop
2015-08-23T16:21:09 < owl-v-> just the board and my computer

2015-08-23T16:30:05 < Ecco> http://i.imgur.com/goQdsw7.png
2015-08-23T16:30:38 < Ecco> (At least if you would scan it for obvious mistake, I'd really appreciate it)
2015-08-23T16:30:50 < dongs> boot0 not connected
2015-08-23T16:30:53 < Ecco> (Note that I'm a beginner and put ~3 days of work into this)
2015-08-23T16:31:00 < Ecco> Damn, indeed, I forgot about BOOTn pins.
2015-08-23T16:31:01 < Ecco> Thanks!
2015-08-23T16:34:58 < Ecco> ok I just grounded boot0
2015-08-23T16:35:12 < dongs> bad idea
2015-08-23T16:35:24 < Ecco> Oh
2015-08-23T16:35:37 < Ecco> Well, I don't care about the embedded bootloader and probably will never boot from SRAM
2015-08-23T16:35:39 < dongs> 10k pulldown, and a jumper to allow shorting it to vcc
2015-08-23T16:36:07 < Ecco> ok, I understood the last part
2015-08-23T16:36:13 < Ecco> but why the pulldown?
2015-08-23T16:36:19 < Ecco> Why not directly to gnd?
2015-08-23T16:36:33 < Steffanx> i case you screw up your sw and lock yourself out (for example)
2015-08-23T16:36:47 < Ecco> can this happen?
2015-08-23T16:36:52 < qyx_> if you tie it directly to gnd, you won't be able to use the jumper
2015-08-23T16:37:03 < Ecco> oh ok
2015-08-23T16:37:10 < Steffanx> and that
2015-08-23T16:37:23 < Ecco> But if I fuck the firmware (which *will* happen, a lot)
2015-08-23T16:37:30 < Ecco> I thought I could just reflash it over the SWD port

2015-08-23T16:38:19 < dongs> if you fuck the firmware
2015-08-23T16:38:22 < dongs> and end up trashing SWD port
2015-08-23T16:38:30 < dongs> well, i guess you could connect under reset
2015-08-23T16:38:48 < qyx_> if you have nrst, yes
2015-08-23T16:38:55 < qyx_> ir just reboot to bootloader
2015-08-23T16:38:56 < Ecco> You mean like re-configuring the GPIOs so that they don't do SWD anymore?
2015-08-23T16:39:00 < Steffanx> no pullup on the reset pin btw Ecco?
2015-08-23T16:39:09 < dongs> or lock up the core so that swd doesnt work
2015-08-23T16:39:22 < Ecco> Yeah, actually I didn't handle the RST pin either :(
2015-08-23T16:39:25 < Ecco> thanks Steffanx!
2015-08-23T16:39:48 < Ecco> Well, regarding that NRST pin
2015-08-23T16:40:05 < Ecco> I understand that it should be driven high for the STM to work at all
2015-08-23T16:40:06 < [7]> 22µA average current including 2.4GHz radio communication every 3 seconds and temperature/humidity measurement every 10s (and storing the results to SPI flash)
2015-08-23T16:40:06 < [7]> is that good, or can we beat it? ;)
2015-08-23T16:40:34 < qyx_> uhm, doesn't the lcd have 25 pins?
2015-08-23T16:40:39 < Ecco> qyx_: yes it does
2015-08-23T16:40:45 < Ecco> But one of them is a duplicate ESD pin
2015-08-23T16:40:53 < Ecco> So I hid one
2015-08-23T16:41:05 < Ecco> But good catch qyx_ :)
2015-08-23T16:41:39 < Ecco> Regarding the NRST pin, my understanding is that is has to be high for the STM32 to run, but it seems to also be part of the SWD bus
2015-08-23T16:42:32 < dongs> so just pull it up wiht 10k and do wahtever you want with it liek that
2015-08-23T16:42:33 < Ecco> How am I supposed to concile these two things?
2015-08-23T16:42:38 < Ecco> oh, ok
2015-08-23T16:42:40 < Ecco> got it
2015-08-23T16:42:55 < qyx_> i would connect CS pin of that lcd to GPIO
2015-08-23T16:43:22 < Ecco> qyx_: Yes, I definitely overlooked that
2015-08-23T16:43:24 < Ecco> Thanks!
2015-08-23T16:43:28 < qyx_> also
2015-08-23T16:43:31 < qyx_> you don't have vdd connected
2015-08-23T16:43:38 < qyx_> this isn't ging to work
2015-08-23T16:43:42 < Ecco> No wait
2015-08-23T16:43:48 < Ecco> I purposedly grounded the CS pin of the LCD
2015-08-23T16:44:07 < Ecco> Because I know there won't be anything else on that SPI bus
2015-08-23T16:44:33 < Ecco> Oh yes crap, I forgot about the VDD part though
2015-08-23T16:44:46 < Ecco> Thanks a lot guys… damn do I feel like a newbie :(
2015-08-23T16:45:04 < qyx_> you can achieve lower current consumption if you deassert CS
2015-08-23T16:45:12 < qyx_> at least for some chips
2015-08-23T16:45:12 < Ecco> Oh
2015-08-23T16:45:25 < Ecco> So i'd just drive CS low whenever the screen is on?
2015-08-23T16:46:17 < qyx_> no, when you want to communicate with the lcd
2015-08-23T16:46:23 < Ecco> oh, ok
2015-08-23T16:46:28 < dongs> datasheet will tell you wat to do with cs/etc
2015-08-23T16:46:34 < dongs> you may need to toggle it
2015-08-23T16:46:34 < Ecco> Yes it indeed does
2015-08-23T16:46:37 < dongs> etc.
2015-08-23T16:46:37 < Ecco> ok
2015-08-23T16:46:43 < Ecco> Allright :)
2015-08-23T16:46:43 < dongs> like between command modes or whatever.
2015-08-23T16:46:56 < dongs> so unless reference schamatic says to ground it, you probly shouldnt
2015-08-23T16:47:11 < Ecco> allright. It does say to connect it to a GPIO so I'll follow your advice
2015-08-23T16:47:35 < Ecco> Back on the BOOT0 pin
2015-08-23T16:47:59 < Ecco> Can I keep it simply grounded provided I won't plan to boot from SRAM nor from the internal bootloader?
2015-08-23T16:48:42 < qyx_> you can, i always regret doing that
2015-08-23T16:48:48 < Ecco> ok :-D
2015-08-23T16:49:01 < Ecco> dongs, you advise a 10K pull-up

2015-08-23T16:49:11 < dongs> 10k pulldown on boot0
2015-08-23T16:49:23 < Ecco> yeah, I meant 10k pull-something

2015-08-23T17:08:57 < Ecco> I know, but Murata had a nice spec for its capacitors
2015-08-23T17:09:08 < Ecco> which gave me the measurements I needed to make the footprint
2015-08-23T17:09:29 < dongs> IPC has recommended footprints for SMD passives
2015-08-23T17:09:33 < dongs> which is what you should be using

2015-08-23T17:10:43 < dongs> i mean the fucking IPC standard
2015-08-23T17:10:50 < jpa-> Ecco: you may want to add series resistors to KBD output signals
2015-08-23T17:11:08 < jpa-> Ecco: otherwise it is easy to burn the GPIO pin if someone presses e.g. A1 and B1 buttons at the same time
2015-08-23T17:11:27 < Ecco> Oooh
2015-08-23T17:11:58 < Ecco> ok, I thought that shorting an input and an output GPIO was ok (which i still think it is)
2015-08-23T17:12:04 < jpa-> yeah
2015-08-23T17:12:07 < Ecco> but I completely overlook shorting two outputs together

2015-08-23T17:12:16 < jpa-> np
2015-08-23T17:13:23 < Ecco> dongs: are the dimensions from IPC publicly available?
2015-08-23T17:13:33 < dongs> Ecco: you should have generic footprints for R0402/0603/0805 C0402/C0603/C0805 etc, they're all same, recommended pad sizes are in IPC standard or you cajn just pick a generic resistor/cap like non-special-non-thick-wahtever stuff and make them used off those and rename int ogeneric.
2015-08-23T17:14:11 < Ecco> Indeed
2015-08-23T17:14:14 < Ecco> That makes sense
2015-08-23T17:14:24 < Ecco> Thing is, I had no idea where to find the standard dimensions
2015-08-23T17:14:31 < zyp> jpa-, why not just OD outputs with pullups?
2015-08-23T17:14:34 < Ecco> So I resorted to components with a datasheet
2015-08-23T17:14:41 < jpa-> zyp: works the same, yeah
2015-08-23T17:14:51 < zyp> and eliminates need for external parts
2015-08-23T17:15:08 < Ecco> zyp: What do you mean by "OD"?
2015-08-23T17:15:12 < zyp> open drain
2015-08-23T17:15:15 < Ecco> ok
2015-08-23T17:15:21 < Ecco> oh, ok
2015-08-23T17:15:22 < zyp> i.e. low or floating
2015-08-23T17:15:39 < zyp> hmm, you don't even need pullups on outputs
2015-08-23T17:15:46 < zyp> input pullups will take care of it anyway
2015-08-23T17:16:15 < jpa-> though that will leave the OD pins floating
2015-08-23T17:16:31 < zyp> well, you're not reading them
2015-08-23T17:16:40 < jpa-> yeah, only matters for power usage
2015-08-23T17:17:25 < Ecco> crap you guys lost me :(
2015-08-23T17:17:27 < zyp> if you're scanning continously, I bet there will be enough capacitance to keep them low between scans
2015-08-23T17:18:24 < jpa-> ok, i agree with zyp :P
2015-08-23T17:18:28 < zyp> power consumed through the pullup on the active OD pin will probably more, unless you disable pullup in software, and that's sort of a hassle
2015-08-23T17:18:42 < jpa-> but yeah, without external resistors do not configure them as push-pull, od is fine :P
2015-08-23T17:18:52 < Ecco> ok
2015-08-23T17:19:21 < Ecco> Let me see the code I've written previously
2015-08-23T17:19:25 < qyx_> jpa, the matrix keyboard destroyer
2015-08-23T17:19:31 -!- Lerg [~Lerg@188.226.45.254] has quit []
2015-08-23T17:19:35 < Ecco> ok, so my output were just marked as output
2015-08-23T17:19:40 < Ecco> (I left everything else default)
2015-08-23T17:19:47 < Ecco> and the input were set as pull-down
2015-08-23T17:20:30 < zyp> when you're using OD, the active output will be low, so you'll have to invert everything
2015-08-23T17:20:52 < Ecco> ok, apparently by default GPIOs are push-pull
2015-08-23T17:20:59 < dongs> pretty sureno
2015-08-23T17:21:07 < dongs> they're inputs or floating or somehing
2015-08-23T17:21:58 < Ecco> I meant GPIOx_OTYPER
2015-08-23T17:22:06 < Ecco> Once you set them up as output, the default output type is open drain
2015-08-23T17:22:11 < Ecco> sorry
2015-08-23T17:22:13 < Ecco> push-pull
2015-08-23T17:22:42 < qyx_> btw
2015-08-23T17:22:49 < qyx_> i am quite interested how this particular display works
2015-08-23T17:22:53 < qyx_> i planned to use them
2015-08-23T17:22:56 < zyp> Ecco, yes, that is true
2015-08-23T17:22:58 < Ecco> I have one right here
2015-08-23T17:23:02 < dongs> qyx, but?
2015-08-23T17:23:05 < Ecco> And got it working
2015-08-23T17:23:09 < Ecco> so feel free to ask questions :-)
2015-08-23T17:23:11 < qyx_> dongs: but i didn't yet
2015-08-23T17:23:32 < Ecco> Well, the documentation is horrible
2015-08-23T17:23:42 < Ecco> (the info is here, but honestly it's poorly organized)
2015-08-23T17:24:09 < Ecco> I'm not sure I understand how opendrain works :(
2015-08-23T17:24:37 < zyp> Ecco, you know how cmos logic works?
2015-08-23T17:24:42 < Ecco> basically it's like "grounded at state 0", and "high-impedance at state 1" ?
2015-08-23T17:24:52 < Ecco> zyp: I had a course about that back at university. Failed pathetically :(
2015-08-23T17:24:56 < Ecco> So the answer is no :-D
2015-08-23T17:25:09 < zyp> there's two transistors stacked, one to ground for driving low, one to vdd for driving high
2015-08-23T17:25:50 < zyp> in a push-pull output, one of those are always on, so the output is either high or low
2015-08-23T17:25:58 < Ecco> ok
2015-08-23T17:26:05 < Ecco> this I undestand
2015-08-23T17:26:12 < zyp> on an input, both are off, so it's floating
2015-08-23T17:26:39 < Ecco> ok
2015-08-23T17:26:39 < zyp> on an open drain output, you disable the top transistor
2015-08-23T17:26:58 < Ecco> so you can only drive low?
2015-08-23T17:27:02 < zyp> so either the lower transistor is driving the output low, or they are both off letting it float
2015-08-23T17:27:05 < zyp> correct
2015-08-23T17:27:19 < Ecco> but it's not really an output then
2015-08-23T17:27:35 < Ecco> it's like half an output
2015-08-23T17:27:46 < zyp> sure it is, you usually have a pullup somewhere that pulls it high when it's floating
2015-08-23T17:27:49 < zyp> it's used for instance with i2c
2015-08-23T17:27:53 < Ecco> oh, ok
2015-08-23T17:28:06 < zyp> i2c has an external pullup, and then each device can drive the bus low
2015-08-23T17:28:13 < Ecco> I understand
2015-08-23T17:28:20 < zyp> that way, multiple devices don't conflict with each other
2015-08-23T17:28:47 < zyp> it's similar in your case, you don't want your outputs to conflict with each other
2015-08-23T17:29:12 < Ecco> gotcha
2015-08-23T17:29:15 < zyp> you just want to drive one row of the keyboard, it doesn't matter to you if the rest are floating
2015-08-23T17:29:26 < Ecco> Indeed
2015-08-23T17:29:36 < Ecco> ok, but then someone has to drive high
2015-08-23T17:29:41 < Ecco> so that's the inputs, right?
2015-08-23T17:29:50 < zyp> you have pullups on the inputs, you need that anyway
2015-08-23T17:30:06 < zyp> because cols that aren't pressed at all would be floating
2015-08-23T17:30:18 < zyp> and cols that are pressed on floating rows would also be floating now
2015-08-23T17:30:30 < Ecco> indeed
2015-08-23T17:30:33 < zyp> but cols that are pressed on low rows will drive the input low
2015-08-23T17:30:37 < Ecco> well, in my previous code
2015-08-23T17:30:51 < Ecco> I was using output as Pullup/pulldown and input as pull-down
2015-08-23T17:31:03 < zyp> yeah, everything will be inverted now
2015-08-23T17:31:05 < Ecco> But this is prone to burning GPIOs
2015-08-23T17:31:17 < Ecco> so I should put the outputs as OD, and input as pull-up
2015-08-23T17:31:18 < zyp> pressed cols would read as 0 and floating cols would read as 1
2015-08-23T17:31:28 < Ecco> ok!
2015-08-23T17:31:43 < Ecco> and that way I avoid adding external passives
2015-08-23T17:31:47 < zyp> yes
2015-08-23T17:31:50 < Ecco> crystal clear
2015-08-23T17:31:51 < Ecco> thanks!
2015-08-23T17:32:00 < Ecco> So no change on the schematics, but changes on the code
2015-08-23T17:32:01 < Ecco> excellent
2015-08-23T17:32:08 < Ecco> thank you, and thanks for all the explanations
2015-08-23T17:32:16 < zyp> I'd even argue that this is a better solution than external passives
2015-08-23T17:32:31 < Ecco> Yeah, like you said, eats less current?
2015-08-23T17:33:09 < zyp> if you have resistors on each output, and somebody presses the same col on two rows, they created a voltage divider
2015-08-23T17:33:18 < dongs> https://www.kickstarter.com/projects/597538543/the-worlds-best-travel-jacket-with-15-features-bau
2015-08-23T17:33:21 < dongs> wat
2015-08-23T17:33:31 < zyp> the col would read as something in the middle between high and low, it'll be undefuned
2015-08-23T17:33:36 < Ecco> indeed
2015-08-23T17:34:15 < zyp> whereas with the open drain scheme, both will be reliably read as pressed
2015-08-23T17:34:40 < Ecco> makes sense
2015-08-23T17:34:51 < Ecco> dongs: What the hell "drink pocket"

2015-08-23T18:06:32 < jpa-> no
2015-08-23T18:06:34 < Ecco> ok :)
2015-08-23T18:06:45 < Ecco> What the hell am I looking at, by the way?
2015-08-23T18:06:52 < zyp> Ecco, well, it just looks unhelpful
2015-08-23T18:06:59 < Ecco> why?
2015-08-23T18:07:01 < zyp> shit is all over the place
2015-08-23T18:07:04 < jpa-> http://essentialscrap.com/doglight/schema.png   i myself prefer to have the pins grouped by function
2015-08-23T18:07:16 < Ecco> Yes I wondered about this
2015-08-23T18:07:19 < Ecco> It makes sense
2015-08-23T18:07:27 < zyp> http://bin.jvnv.net/f/SU1IJ.png <- same
2015-08-23T18:07:29 < Ecco> I thought "this way it's easy to not miss any pin"
2015-08-23T18:07:38 < Ecco> But now that I think about it, you're obviously right
2015-08-23T18:07:45 < jpa-> yeah, need to doublecheck that you have all of them
2015-08-23T18:07:58 < qyx_> same here
2015-08-23T18:08:19 < Ecco> Indeed
2015-08-23T18:08:36 < Ecco> zyp: The NRST pin seems to not be pulled high in the schematic you just uploaded
2015-08-23T18:08:48 < jpa-> it has internal pull-up
2015-08-23T18:08:54 < jpa-> which is pretty weak though
2015-08-23T18:08:58 < zyp> Ecco, the schematic is supposed to show you how everything connects logically, not physically
2015-08-23T18:09:08 < Ecco> zyp: indeed. This I figured out
2015-08-23T18:09:19 < Ecco> Actually
2015-08-23T18:09:29 < qyx_> mhm, i don't like parts being split into multiple symbols
2015-08-23T18:09:29 < Ecco> I'm bothered that most CAD software make me lay out the whole thing
2015-08-23T18:09:42 < Ecco> we should just tell him about a graph
2015-08-23T18:09:47 < Ecco> and let the software do the layout
2015-08-23T18:09:53 < jpa-> qyx_: it does help when you get to hundreds of pins, though
2015-08-23T18:10:06 < jpa-> Ecco: you can write raw netlist files :P
2015-08-23T18:10:11 < Ecco> So regarding the NRST file
2015-08-23T18:10:11 < zyp> qyx_, it's preferable to having pins along top and bottom edge
2015-08-23T18:10:16 < Ecco> you mean I don't need to pull it up myself?
2015-08-23T18:10:39 < zyp> Ecco, yes
2015-08-23T18:10:43 < Ecco> so why bother?
2015-08-23T18:10:59 < zyp> I've never had a problem with just relying on the internal nrst pullup on stm32
2015-08-23T18:11:14 < jpa-> i have had attaching a debugging cable reset the cpu
2015-08-23T18:11:25 < karlp> Ecco: there is a doc from st called " getting started with hardware " or someshit, that outlines what they really recommend for these things too.
2015-08-23T18:11:25 < jpa-> due to capacitance in the cable between nrst and gnd wires

2015-08-23T21:00:24 < [7]> kinda depends on the application
2015-08-23T21:00:41 < [7]> if the purpose of that is mostly to have easy access to VDD everywhere, that might be a valid approach

2015-08-23T21:11:31 < zyp> it was a led matrix board with a bunch of pfets for driving high side, so it made sense to have a vdd plane for supplying all the pfets

2015-08-23T23:50:19 < karlp> BrainDamage: working on some libopencm3 usb stuff, want to make sure it behaves the same way as some linux gadgets, thought it would be easier if I actually had to to reference with :)
2015-08-23T23:55:52 < BrainDamage> c1 is probably the best choice then, there's cheaper alternative but require some fiddling to get to work
2015-08-23T23:56:24 < upgrdman_> re: my linker error, figured it out. my dumb ass ran out of flash. dividing by 4096 can become a bit shift, dividing by 4095 was causing sw div lib to be included, which i didn't have room for. lol.

2015-08-24T00:50:36 < karlp> bloody usb, managed to lock up my desktop with this shit
2015-08-24T00:50:59 < upgrdman> so im kinda lazy. odroid c1+ versus bbb, which is better and why?
2015-08-24T00:51:53 < BrainDamage> depends what do you need
2015-08-24T00:52:07 < BrainDamage> a shitload of gpio, or a good cpu / ethernet?
2015-08-24T00:52:14 < BrainDamage> for the first, beaglebone, for the latter, c1
2015-08-24T00:52:41 < karlp> c+1 and bbb can both do usb gadget, pi2 can't.
2015-08-24T00:52:42 < BrainDamage> a pi 2 doesn't have more gpio than a c1
2015-08-24T00:53:19 < BrainDamage> the only selling point of a pi2 is the gpu that's not the clusterfuck of a mali that the c1 mounts
2015-08-24T00:53:25 < BrainDamage> otherwise it's worse in every possible way
2015-08-24T00:55:04 < karlp> so what, your summary is videocore works, but closed, mali is somewhat mor eopen, but a mess of chunks of blobs all over the place?
2015-08-24T00:55:44 < BrainDamage> yes, and somehow fiddly to get to work too
2015-08-24T00:56:38 < BrainDamage> ( also pay in mind it's actually a 3d accelerator, 2d and other shit are handled by other components in the soc )
2015-08-24T00:57:07 < Laurenceb__> rpi has i2c too
2015-08-24T00:57:13 < Laurenceb__>  :P
2015-08-24T00:57:14 < BrainDamage> so if you don't care about gpgpu, video de-encoding, or 3d acceleration, you can just ignore it
2015-08-24T00:57:19 < Laurenceb__> lul
2015-08-24T00:57:48 < Laurenceb__> Fleck: so read the stperiph codex
2015-08-24T00:58:13 < Fleck> Laurenceb__: yeah, I am right now :D
2015-08-24T00:58:24 < Laurenceb__> Fleck: that code is in use in commercial products... but it might break in other uses lol
2015-08-24T00:58:27 < Fleck> Laurenceb__: seems like, I2C_CR2 FREQ value is ignored, I did math backwards, I2C clock is 36MHz :D should be 8MHz
2015-08-24T00:58:53 < Laurenceb__> I've used it in a few products and its worked ok so far....
2015-08-24T00:58:55 < karlp> god this fucking hub is shit
2015-08-24T00:58:59 < Laurenceb__> debugging took forever
2015-08-24T00:59:04 < upgrdman> any cheap SBCs with SATA? tempted to replace my NAS with something a bit less shitty.
2015-08-24T00:59:52 < BrainDamage> linuxino has a single sata and a gigabit ethenet
2015-08-24T01:00:07 < BrainDamage> you'll need a port multiplier tough
2015-08-24T01:01:18 < BrainDamage> also, you'll run into dma / cpu limit if yo try to use it at full gigabit speed
2015-08-24T01:01:46 < BrainDamage> howrever, from my experience ( i'm using one as nas ) you're limited by the hd
2015-08-24T01:01:48 < upgrdman> my dreams. crushed.
2015-08-24T01:02:40 < Fleck> Laurenceb__: meh, maybe I missunderstood what that register does :D and it should be 36MHz...? The FREQ bits must be configured with the APB clock frequency value (I2C peripheral
2015-08-24T01:02:41 < Fleck> connected to APB). The FREQ field is used by the peripheral to generate data setup and hold times compliant with the I2C specifications. << this is from datasheet... I was thinking of it as prescaler somekind, where I can set my own freq. for i2c :D
2015-08-24T01:03:12 < Fleck> at least, that's what stdperiph seems to be doing ;D
2015-08-24T01:03:28 < Laurenceb__> ok
2015-08-24T01:03:38 < Laurenceb__> good luck with all the other bugs
2015-08-24T01:03:44 < Fleck> ;p

2015-08-24T03:02:25 < upgrdman> c implicit casting... iirc if you're doing arithmetic with ints and longs, the ints get's autopromoted to longs, right?
2015-08-24T03:03:05 < upgrdman> e.g. int a = 1; int b = a + 2L; ... a gets promoted to a long, right?
2015-08-24T03:13:23 < zyp> b is still an int, so that's kinda irrelevant
2015-08-24T03:19:59 < upgrdman> i know but for more complex shits...
2015-08-24T03:20:47 < upgrdman> int i = someInt * someOtherInt / 4096L; would be important
2015-08-24T03:21:04 < upgrdman> if si and soi are bigish
2015-08-24T03:23:10 < zyp> no, that wouldn't work either way
2015-08-24T03:23:23 < zyp> since multiplication happens before division
2015-08-24T03:23:40 < upgrdman> oh the promo is per pair, not for the entire expr?

2015-08-24T14:47:19 < dongs> I designed the Zano hardware using key components (pic32mz) before it was officially released. All the other parts are also newly released. Anything that might need upgrading I designed in as a module (camera, RGB etc).
2015-08-24T14:48:21 < jpa-> isn't the pic32 the first thing they'd need to upgrade :)
2015-08-24T14:48:46 < dongs> So for us, we added a local RF (915/868MHz) which can be tuned to 920MHZ for certain countries too. This local RF device allows many Zano's to communicate directly with each other without the need for WIFI or authentication. Your Zano when in flight (in v1.1 once we enable this transceiver) will transmit basic data about itself. Speed, position, altitude, direction etc. This information can be received by other Zano's in the same park or place and be used for Zano's

2015-08-24T17:16:26 < trepidacious> What's the most accurate way to measure the time between two rising edges of an input? I'm guessing using a timer, can the timer itself start on one rising edge and stop on the second?
2015-08-24T17:16:34 < trepidacious> It would be great to avoid the need to use interrupts
2015-08-24T17:16:36 < dongs> yes
2015-08-24T17:16:43 < dongs> just use input capture
2015-08-24T17:16:46 < dongs> it will do exactly that
2015-08-24T17:16:57 < dongs> how 'often' is the measurement?
2015-08-24T17:17:08 < dongs> do you want it just once, or repeatedly?
2015-08-24T17:18:33 < trepidacious> Repeatedly, and it will be something like 10Hz to say 10KHz, I'll be able to tie it down a bit more when I've tried it out
2015-08-24T17:18:51 < trepidacious> Looks like I want 2.3 in this AN? http://www.st.com/web/en/resource/technical/document/application_note/DM00042534.pdf
2015-08-24T17:20:14 < dongs> yeah
2015-08-24T17:20:37 < trepidacious> Great thanks, I ran into a few google results with people using interrupts, which seemed crazy

2015-08-24T17:21:00 < dongs> not sur wha you mean by "avoid interrupts", you can just have it DMA stuff if its repeatedly, i don't really know how you can avoid having an interrupt when it finishes the compare.
2015-08-24T17:21:28 < dongs> you can simply just copy the capture value into wherever and exit interrupt. don't think its such big overhead.
2015-08-24T17:22:02 < trepidacious> dongs: Ah yup, to read the timer. For some reason I thought they were trying to use the interrupt to do the measurement, I'm probably mistaken
2015-08-24T17:22:09 < dongs> no
2015-08-24T17:22:12 < dongs> measurement is hardware
2015-08-24T17:22:19 < dongs> and y ou get a 'capture complete' interrupt
2015-08-24T17:22:25 < dongs> this is not avr
2015-08-24T17:22:30 < trepidacious> Yeah :)
2015-08-24T17:22:33 < trepidacious> http://stm32f4-discovery.com/2015/01/library-48-measure-pwm-input-signal-stm32f4/
2015-08-24T17:24:23 < dongs> there's TIMx_CC or TIM_ irqhandlers i think advanced timers have _CC whlie the regular ones you just enable _CC bits in interrupt mask
2015-08-24T17:25:42 < dongs> and you just read the time interval out of TIMx->CCRy and clear interrupt flag, done.
2015-08-24T17:26:07 < trepidacious> I'll have a look, the main thing is it's good to know it's definitely possible, I guess it will be accurate to one tick of the timer I'm using, which should be pretty good at 84MHz
2015-08-24T17:26:33 < dongs> there's also some filtering available
2015-08-24T17:26:40 < dongs> for anti-glitch and in general
2015-08-24T17:26:55 < dongs> it's rather unlikely your pulse rise will be that quick @ 84mhz
2015-08-24T17:27:57 < trepidacious> Yup, I want to get a good number of ticks per period so I can have reasonable resolution, but it probably won't beed to be 84MHz
2015-08-24T17:33:16 < rewolff> At 84 mHz, you'll need to consider timer overflow. (~47 seconds at 32bits, ~1ms at 16 bits....) (i.e. for your 10Hz - 10kHz you're ok with a 32-bit counter, and will have to prescale and accept lower resolution if you're going to use a 16-bit timer).
2015-08-24T17:37:06 < trepidacious> yup I was thinking 32 bit timer

2015-08-24T18:05:32 < englishman> did you read the datasheet
2015-08-24T18:05:34 < englishman> the link is right there
2015-08-24T18:05:34 < upgrdman> nm. 300 degrees :(
2015-08-24T18:05:38 < upgrdman> just now :)
2015-08-24T18:07:00 < englishman> i dont think you want that one anyway
2015-08-24T18:07:07 < englishman> <300 in stock, 14 week lead time
2015-08-24T18:08:49 < upgrdman> i just want a pot that can do >360 degrees, but i don't need a full 10-turn pot
2015-08-24T18:08:53 < upgrdman> like 2 - 3 turns would be nice
2015-08-24T18:09:55 < Fleck> upgrdman: do you even datasheet, bro? :D

2015-08-24T22:10:21 < Steffanx> or hidden very well
2015-08-24T22:10:23 < englishman> multiple desktops? like GNOME and xfce?

2015-08-24T22:10:50 < BrainDamage> he means virtual desktops
2015-08-24T22:11:23 < BrainDamage> so you can partk a set of programs to a virtual desktop, then decide where/if it gets rendered
2015-08-24T22:11:30 < BrainDamage> eg send to a monitor or don't render
2015-08-24T22:11:35 < BrainDamage> and switch between them
2015-08-24T22:12:34 < englishman> like minimize and alt-tab?
2015-08-24T22:12:51 < qyx_> wat, no
2015-08-24T22:12:56 < BrainDamage> no
2015-08-24T22:13:05 < qyx_> like if you had multiple monitors on your desktop
2015-08-24T22:13:14 < qyx_> and you can switch your eyes between them
2015-08-24T22:13:24 < qyx_> and have different set of windows on each
2015-08-24T22:13:35 < englishman> thats typically how i work
2015-08-24T22:13:37 < BrainDamage> think of it like minimize, alt tab, etc, but for whole desktops
2015-08-24T22:13:48 < BrainDamage> not single apps
2015-08-24T22:13:54 < englishman> oh mac had that

2015-08-24T22:14:35 < englishman> didnt like it, kept losing windows

2015-08-25T00:37:13 < zyp> IIRC there's no option for SWO on M0 at all
2015-08-25T00:37:26 < zyp> so I'll go with «no»
2015-08-25T00:37:32 < upgrdman> k
2015-08-25T00:37:45 < upgrdman> that explains why i couldn't find a pin for swo :)
2015-08-25T00:39:14 < karlp> you get some of the internal pieces but it just buffers into some ram, and you hav eto read it out over swd.
2015-08-25T00:39:20 < upgrdman> is swo required for semihosting, or can that still be done with just clk/io pins?
2015-08-25T00:39:33 < karlp> arm has MTB, and atmel has DCC, and jlink has a lib you can link that all do the same thing
2015-08-25T00:39:40 < karlp> swo is not related to semihosting at all.
2015-08-25T00:39:48 < upgrdman> o ok
2015-08-25T00:40:02 < karlp> semihosting is just special breakpoitn opcodes that get you stdio.h on the host.
2015-08-25T00:40:19 < upgrdman> any idea if openocd can semihost with stm32?

2015-08-25T05:41:36 < Roklobsta> by work you mean cook some more?
2015-08-25T05:44:08 < Roklobsta> what are you daccing?

2015-08-25T05:45:05 < Roklobsta> oh zzzzzz
2015-08-25T05:45:16 < Roklobsta> been there done that
2015-08-25T05:45:19 < Roklobsta> dds is easy
2015-08-25T05:45:38 < Roklobsta> the trick is getting rid of spurs
2015-08-25T05:45:54 < Roklobsta> i got rid of spurs
2015-08-25T05:46:05 < Roklobsta> i read a xilinx app note.
2015-08-25T05:46:16 < Roklobsta> BTW it's got red herrings in it to make you fail.
2015-08-25T05:46:30 < Roklobsta> i saw through their red herrings and go it to work
2015-08-25T05:46:58 < Roklobsta> this one was done by fred harris and friends who eat bananas, not bend them.
2015-08-25T05:47:58 < Roklobsta> fuck i hope it's in my ~/Projects dir
2015-08-25T05:48:03 < Roklobsta> been ages
2015-08-25T05:48:35 < ds2> hmmmm engineered bananas
2015-08-25T05:48:58 < Roklobsta> i'm actually eating a banana lolly now
2015-08-25T05:49:56 < upgrdman> spurs == unwanted spikes in the freq domain?
2015-08-25T05:50:19 < ds2> or things on a pair of boots...
2015-08-25T05:50:25 < englishman> banana engineers are probably quite talented
2015-08-25T05:50:32 < englishman> those things should be extinct by now
2015-08-25T05:52:39 < Roklobsta> the aritcles is based on "FPGA Signal Processing Using Sigma-Delta Modulation"
2015-08-25T05:52:48 < Roklobsta> but i can't find the xilinx app notes
2015-08-25T05:53:18 < Roklobsta> i'm not happy, i have lost this stuff plus code.  damnit
2015-08-25T05:54:13 < Roklobsta> sigma delta modulation works really well.
2015-08-25T05:54:29 < Roklobsta> basically it's using the 1st derivative in the feedback loop
2015-08-25T05:55:01 < Roklobsta> as part of the error signa;
2015-08-25T05:55:39 < Roklobsta> suppress spurs
2015-08-25T05:55:48 < Roklobsta> dither works to a point.
2015-08-25T05:56:16 < Roklobsta> i got it working nice in C with integer maths
2015-08-25T05:56:38 < Roklobsta> as part of and idle fantasy making a dsp library
2015-08-25T05:58:05 < Roklobsta> oh no Taylor Series, not sigma delta

2015-08-25T18:01:07 < mtbg> ok, but still it is better to have a flag like USE_SEMIHOSTING
2015-08-25T18:01:21 < mtbg> instead of checking -g setting using macros
2015-08-25T18:01:33 < upgrdman> but them i have to manually -D or #define it, like some sort of savage.
2015-08-25T18:02:05 < emeb> or put that define in the same place you put the -g?

2015-08-25T19:47:32 < upgrdman> anyone know where i can find something like this on mouser or digikey? http://d1gsvnjtkwr6dd.cloudfront.net/large/CN-DU-H02_LRG.jpg    it's just a typical .1" female header, but for crimping, not soldering

2015-08-26T02:35:20 < emeb> they're fine for simple adjustments, but the detents and mechanical switch bounce make them pretty awful for fast & precise frequency changes
2015-08-26T02:35:43 < ds2> oh
2015-08-26T02:35:47 < emeb> need optical for no bounce
2015-08-26T02:36:01 < emeb> need no detents for smooth operation w/o drag on spinning knob
2015-08-26T02:36:09 < ds2> always thought encoder means they handle the debouncing for you
2015-08-26T02:36:17 < emeb> if only. :)
2015-08-26T02:36:26 < ds2> (vs a rotary switch...)
2015-08-26T02:36:41 < emeb> all they give you is quadrature switch closures
2015-08-26T02:37:23 < ds2> makes me wonder if an ipod style cap sense dial is easier then
2015-08-26T02:37:42 < emeb> perhaps for some applications
2015-08-26T02:38:10 < emeb> but capsense wouldn't have the inertia that a nice weighted knob does.
2015-08-26T02:38:44 < emeb> plus, the electronic overhead of the capsense controller - more complex than a simple optical interrupter.
2015-08-26T02:40:24 < ds2> didn't you have to make the mechanicals like a know and rod to connect to the mice?

2015-08-26T15:39:24 < stukdev_> gyx: yes, that its the doc that i says... so i don't understand if there is or not... In the doc there's...in the code i get handler error, and this http://stm32f4-discovery.com/2014/12/library-45-interface-backup-sram-on-stm32f4/ says 401 haven't bkp register
2015-08-26T15:39:37 < mtbg> there is no 4kB backup sram
2015-08-26T15:39:41 < qyx_> wat
2015-08-26T15:39:43 < mtbg> there are some rtc backup registers
2015-08-26T15:39:45 < qyx_> backup sram != backup registers
2015-08-26T15:39:59 < qyx_> also
2015-08-26T15:41:01 < stukdev_> shit... i think was the same -.-'
2015-08-26T15:41:19 < qyx_> 0x4000 2800 - 0x4000 2BFF RTC & BKP Registers
2015-08-26T15:41:19 < stukdev_> so what is the backup register for rtc?!?
2015-08-26T15:41:53 < jubatus> dongs: unfortunately I don't have NDA u-blox datasheets
2015-08-26T15:41:55 < jubatus> do you ?
2015-08-26T15:42:13 < jubatus> this is the latest chip. M8030
2015-08-26T15:42:30 < mtbg> rtc backup registers are for general use also
2015-08-26T15:42:42 < mtbg> and are backed up by rtc battery if present
2015-08-26T15:42:47 < qyx_> dongs: lol that guy claims he has a fatfs library
2015-08-26T15:43:18 < stukdev_> mtbg: ok well, so  can i use that without battery but only with normal supply for set a bit to go in bootloader mode?
2015-08-26T15:43:33 < mtbg> probably
2015-08-26T15:43:58 < stukdev_> mtbg: so i've only to search the correct address of that register
2015-08-26T15:44:20 < qyx_> i copypasted it
2015-08-26T15:44:33 < qyx_> + 0x50 offset for the first one
2015-08-26T15:44:47 < mtbg> I think rtc needs to be enabled too
2015-08-26T15:44:50 < qyx_> page 39 in your doc
2015-08-26T15:45:01 < stukdev_> gyx i mean BKP0R
2015-08-26T15:45:16 < stukdev_> i don't want use "manual" code

2015-08-26T16:15:43 < trepidacious> stukdev_: You want to pass data to your bootloader?
2015-08-26T16:16:18 < stukdev_> trepidacious: i want go in dfu mode, one method was set a bit somewhere reset the board, check that bit on call the bootloader address
2015-08-26T16:17:27 < zyp> stukdev_, you don't need backup registers for that
2015-08-26T16:17:33 < trepidacious> Yeah setting a BKP register with a kind of command code then resetting and checking in the bootloader works fine
2015-08-26T16:18:03 < zyp> just use plain sram
2015-08-26T16:18:04 < trepidacious> stukdev_: I would recommend using an actual code rather than a bit in case the bkp register just randomly has that bit set ;)
2015-08-26T16:18:23 < zyp> and yes, use a magic value of some sort
2015-08-26T16:19:19 < trepidacious> zyp: I did think SRAM would be preserved, but I think I couldn't find anything to make me completely confident all SRAM is left alone on reset
2015-08-26T16:19:29 < zyp> I wrote a bootloader once, for which I considered using backup registers, then I concluded that turning on the rtc was too much work for that
2015-08-26T16:19:41 < zyp> so I just stuffed a magic word into ccm instead
2015-08-26T16:19:42 < trepidacious> zyp: I had RTC on anyway, so it didn't matter
2015-08-26T16:19:45 < zyp> this was on f3 with ccm
2015-08-26T16:19:59 < trepidacious> zyp: Do you need to turn on RTC to use BKP registers?
2015-08-26T16:20:01 < zyp> well, the bootloader doesn't use RTC normally, does it?
2015-08-26T16:20:16 < zyp> yes, you need to unlock backup domain, since that's where they are stored
2015-08-26T16:20:23 < trepidacious> zyp: It's still enabled though, it needs to keep counting time :)
2015-08-26T16:20:38 < trepidacious> otherwise you would lose time when you reset
2015-08-26T16:20:58 < zyp> trepidacious, assuming that you didn't have a vbat power failure
2015-08-26T16:21:21 < zyp> and IIRC, backup domain locks on reset
2015-08-26T16:21:46 < trepidacious> zyp: Ah maybe, I thought it was still accessible
2015-08-26T16:22:13 < trepidacious> If SRAM is definitely ok across reset that does seem simpler
2015-08-26T16:22:23 < zyp> well, might still be readable, but you'll want to write the register to clear the magic word a well
2015-08-26T16:22:47 < zyp> yes, SRAM content is preserved as long as you have power
2015-08-26T16:27:32 < trepidacious> That's good to know, a lot more space for passing messages, although I guess it's unlikely to be needed
2015-08-26T16:29:54 < stukdev_> but f4 haven't SRAM backup register :)
2015-08-26T16:30:18 < trepidacious> I'm sure some F4's have battery backed SRAM
2015-08-26T16:31:17 < jpa-> IIRC many of them have 4kB of backup-domain SRAM
2015-08-26T16:31:28 < jpa-> and all have the 100 bytes or so of RTC backup regs
2015-08-26T16:33:09 < jpa-> regarding SRAM over resets: make sure that crt0 doesn't clear it; ie. probably need a separate .noinit section for that

2015-08-26T19:10:24 < PointerToNull> Hey guys, I'm looking for how my main() function gets call once I turn on my microcontroller. I kind of know that there is something like a "Reset Vector" and "Startup Code" before the main() but is unclear to me how they works. There is something out there that let me understeand how I get to the main() ? Thanks!
2015-08-26T19:11:53 < karlp> you can read arm docs on what has to be in flash and how that turns into a reset vector and stack pointer
2015-08-26T19:12:05 < karlp> if you want to know how the reset vector gets to main, it just calls it.
2015-08-26T19:12:58 < karlp> kinda like this:
2015-08-26T19:13:03 < karlp> https://github.com/libopencm3/libopencm3/blob/master/lib/cm3/vector.c#L94

2015-08-26T19:14:20 < PointerToNull> karlp, thanks for the reply, but I don't even know what a reset vector is.. A fixed hardware specified pointer do a memory address where I have to put the address of my sturtup code function?
2015-08-26T19:15:53 < PointerToNull> Because so far I just write code from main() and so on.. Never had the opportunity to go deeper, but is instead what I like to do now :)
2015-08-26T19:17:09 < PointerToNull> Is there a guide or documentation with each step to let me understeand how and what the microcontroller does before getting to the main()?
2015-08-26T19:19:23 < jpa-> PointerToNull: yeah, vector table is by default at the very beginning of flash
2015-08-26T19:19:49 < jpa-> so when the processor boots, it will load stack pointer value from 0x0000 and program counter value from 0x0004
2015-08-26T19:20:10 < jpa-> same way when your program inevitably crashes, it will load the crash handler address from 0x0008
2015-08-26T19:20:49 < jpa-> (or 0x000C actually, remembered wrong)
2015-08-26T19:20:54 < jpa-> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0552a/BABIFJFG.html
2015-08-26T19:22:51 < PointerToNull> Thanks a lot jpa- ! But once the stack pointer is loaded what is the step after?
2015-08-26T19:23:29 < jpa-> to load the program counter (and loading the program counter is just a fancy way of saying "jump to this address")
2015-08-26T19:23:50 < jpa-> so then it starts executing your code, or whatever code happens to be at that address
2015-08-26T19:24:11 < jpa-> (the reason why it loads stack pointer first is so that you do not need an assembler wrapper for boot code)

2015-08-26T19:27:05 < PointerToNull> because where/when/how the stack and heap are conficured? I do not do it in the main, I think is one level deeper right?
2015-08-26T19:27:32 < jpa-> PointerToNull: depends on what c runtime you use
2015-08-26T19:27:43 < jpa-> newlib has its own startup code, so usually the reset vector will point there
2015-08-26T19:28:26 < jpa-> https://svn.kapsi.fi/jpa/paatti/interrupt_vectors.c   you can also write your own startup code like i have here

2015-08-26T19:36:02 < PointerToNull> I see, great! So, to recap: the machine jumps automatically to a fixed address, here is where I have to configure the reset vector, where I set the stack pointer and the program counter and other pointers, than it will jump to a function in the C Library Runtime that performs the configuration for the stack and for the heap, and than it will call my main() function right?
2015-08-26T19:36:43 < PointerToNull> I forgot to mention you jpa-
2015-08-26T19:37:48 < karlp> no, the machine doesn't jump to a fixed address.
2015-08-26T19:38:01 < karlp> it loads its initual pc value from a fixed offset in flash.
2015-08-26T19:38:17 < jpa-> yeah, "jump to fixed address" was how the old ARM7 used to work
2015-08-26T19:38:42 < karlp> which is why it needed asm startup.
2015-08-26T19:38:56 < jpa-> cortex-m just has the address directly there and the processor just loads it from there.. as if     mov r3, 0x0004; ldr pc, [r3]    had been executed

2015-08-26T20:27:13 < upgrdman> e.g. void suckIt(int i = 3; ...} i is located on the stack
2015-08-26T20:27:27 < upgrdman> e.g. void suckIt(static int i = 3; ...} i is located on the heap
2015-08-26T20:28:44 < kakimir> what happens there
2015-08-26T20:29:01 < upgrdman> on the heap?
2015-08-26T20:29:20 < kakimir> oh it's function definition I assumed it was declaration

2015-08-26T20:29:34 < upgrdman> karlp, k thx
2015-08-26T20:29:45 < upgrdman> int q = 0; // .bss?
2015-08-26T20:29:55 < karlp> don't remember .)
2015-08-26T20:30:04 < upgrdman> fair enough
2015-08-26T20:30:08 < karlp> that's one of those things where I think it's legal, but you end up wasting flash
2015-08-26T20:30:22 < karlp> because it has to keep the initial value (0) in .data,
2015-08-26T20:30:25 < karlp> which is just pointless.
2015-08-26T20:30:45 < karlp> but trying to remember what things are reliably init'd to zero, and which aren't is out of my brane.
2015-08-26T20:30:48 < kakimir> there is no rule that bss should be zero
2015-08-26T20:31:03 < karlp> something like, int q; // not zeroed, static int q; // gauranteed to be zero
2015-08-26T20:31:29 < kakimir> what
2015-08-26T20:31:41 < kakimir> really?
2015-08-26T20:31:52 < kakimir> completelly another animal?
2015-08-26T20:32:50 < upgrdman> text segment is opcodes and constant data, right? and data segment is values that get copied to RAM to init variables?

2015-08-26T20:53:28 < zyp> in what sense?
2015-08-26T20:55:24 < zyp> karlp, that's not right
2015-08-26T20:55:34 < zyp> karlp, all global vars are guaranteed to be initialized
2015-08-26T20:56:20 < zyp> keep in mind that static means different stuff in different context
2015-08-26T20:56:46 < zyp> a static global variable just means that the symbol doesn't get exported
2015-08-26T20:57:09 < zyp> a static function variable on the other hand means that it gets stored globally, not on the stack
2015-08-26T20:57:11 < mtbg> also, .data/.bss != heap
2015-08-26T20:57:18 < zyp> so for function variables, what you said is true
2015-08-26T20:57:39 < zyp> and yes, heap is usually a separate memory region that's not initialized
2015-08-26T20:57:47 < mtbg> conventionally, heap is used to describe space for dynamic allocations
2015-08-26T20:58:52 < zyp> it doesn't make sense to zero-initialize heap and stack, because once it has been allocated and freed once, you now have garbage there again, so you can't rely on it being initialized either way
2015-08-26T20:59:43 < zyp> mtbg, everybody knows that
2015-08-26T20:59:47 < kakimir> http://img.pr0gramm.com/2015/08/24/92de6a5c68811849.jpg
2015-08-26T20:59:57 < mtbg> zyp: apparently not :>
2015-08-26T21:00:44 < zyp> mtbg, but speaking from a linker script perspective, nothing prevents you from extending .bss to end of memory and putting heap and stack inside the cleared region
2015-08-26T21:01:06 < zyp> it's just a waste of time to initialize it when user code can't rely on it being initialized anyway
2015-08-26T21:01:37 < mtbg> yrp
2015-08-26T21:01:39 < mtbg> yep

2015-08-27T04:10:29 < dongs> fuck nxp some more
2015-08-27T04:10:40 < zyp> was thinking about dicking around with some CAN shit, so I picked up one of the evalboards along with f7disco and nrf52
2015-08-27T04:11:14 < zyp> because lpc11c got a built in can transceiver
2015-08-27T04:12:58 < zyp> eh, even smaller, I'd say, it's just an so8 part
2015-08-27T04:13:06 < zyp> but a part less is a part less
2015-08-27T04:15:01 < zyp> idk, depends on the application I assume
2015-08-27T04:15:07 < dongs> theres no standard
2015-08-27T04:15:22 < zyp> there's lots of standards built on CAN that defines connectors
2015-08-27T04:17:20 < zyp> I haven't really done the price comparison yet though, an f0 or whatever and a transceiver might be cheap enough
2015-08-27T04:17:22 < dongs> got 8 12V/7Ah SLAs for $16/ea
2015-08-27T04:17:31 < dongs> i found out all of my UPSs were fucking trashed
2015-08-27T04:17:38 < dongs> barely lasted 1 minute
2015-08-27T04:17:42 < dongs> time to refresh batteries
2015-08-27T04:19:37 < zyp> also, it looks like the built-in can transceiver requires a 5V supply
2015-08-27T04:20:14 < zyp> save a transceiver, add another reg
2015-08-27T04:20:20 < dongs> ownt
2015-08-27T04:20:52 < zyp> a bit curious how pricing would work out anyway
2015-08-27T04:21:07 < zyp> dongs, any idea how much 3.3V can transceivers are?
2015-08-27T04:21:24 < dongs> er like < $.50 i guess? i think i sampled some before..
2015-08-27T04:21:39 < zyp> I seem to recall they were pricy last time I touched can, like three-four years ago
2015-08-27T04:23:08 < zyp> oh well, I'm going to dick around with this some more, and when I get fed up I'll just design a board with a transceiver and a stm32f0 or something
2015-08-27T04:25:27 < zyp> $2 is kinda expensive, I want this board to be super cheap
2015-08-27T04:25:42 < zyp> idea is lots of cheap simple nodes on a CAN bus

2015-08-27T04:32:21 < zyp> R2COM, yeah, since before it got named C++11
2015-08-27T04:32:32 < dongs> back then it was called 'gcc extensions'

2015-08-27T04:33:05 < zyp> no, it went as C++0x before it was finalized
2015-08-27T04:33:11 < dongs> that wasnt already done in C
2015-08-27T04:33:12 < dongs> properly
2015-08-27T04:33:33 < zyp> dongs, so you'll never use C11 either?
2015-08-27T04:34:20 < dongs> what could tehy possibly add to C
2015-08-27T04:34:26 < dongs> its already perfect
2015-08-27T04:34:43 < zyp> hmm, not much interesting actually
2015-08-27T04:34:53 < zyp> https://en.wikipedia.org/wiki/C11_(C_standard_revision) <- the list of changes is pretty small and boring

2015-08-27T04:35:18 < zyp> anonymous structs and unions are useful
2015-08-27T04:35:24 < zyp> and static assertions, I guess
2015-08-27T04:35:47 < zyp> the rest looks pretty unuseful for embedded

2015-08-27T04:51:21 < dongs> er zyp your timer.h is pretty useless
2015-08-27T04:51:26 < zyp> the rest is a bunch of mess
2015-08-27T04:51:41 < dongs> dont think it even covers all timers on F4
2015-08-27T04:51:53 < dongs> there's a bunch of 2-channel TIM14/15/16 or soemthing
2015-08-27T04:52:15 < zyp> dongs, sure
2015-08-27T04:52:44 < zyp> R2COM, because it was written before class enums existed
2015-08-27T04:53:06 < zyp> doesn't matter either way

2015-08-27T04:54:58 < zyp> dongs, and timers have so many features that it's pretty hard to make a higher level API for it that's actually useful without sacrificing flexibility

2015-08-27T04:55:35 < dongs> shit like setting up timebase/etc

2015-08-27T04:58:31 < zyp> and I'll rather use that half assed definition than another lib that's full ass
2015-08-27T04:59:34 < zyp> idk, if I started from scratch today I might have went with libopencm3 instead

2015-08-27T16:42:02 < jubatus> low levels of radiation would kill off pre-cancerous and other not-completely-fit cells
2015-08-27T16:42:08 < jubatus> it could possibly improve your health

2015-08-27T17:59:57 < upgrdman> does c or c++ allow you to list parameter names next to the argument values? like init_foo(param1='myArg', param2=69);
2015-08-27T18:00:08 < upgrdman> i seem to recall this being thought about for c11?
2015-08-27T18:01:44 < __rob> you mean default values for arguments ?

2015-08-27T18:02:06 < upgrdman> no i mean being able to specifiy what each argument is
2015-08-27T18:03:09 < jpa-> in C99 you can also do     myfunction((myfunction_args_t){.foobar = 123, .baabaa = 456});   but never seen anyone do that
2015-08-27T18:04:18 < jpa-> the c99 struct thingy is nice in the way that putting bazillion arguments into struct is not a bad idea in itself, so it's up to the caller how he wants to do it

2015-08-27T23:18:46 < mtbg> hence raspberry pi is slower than 1 atmega

2015-08-27T23:24:08 < zyp> huh?
2015-08-27T23:24:53 < zyp> I'm not sure what you're trying to claim, but I've made my own fpga boards before without any problems
2015-08-27T23:25:53 < Yoduza> what is the analog of I2C or SPI in xilinx ?
2015-08-27T23:26:10 < zyp> your question doesn't make sense
2015-08-27T23:27:11 < Yoduza> ok. How your board with fpga communicate chips ? Or on board only 1 fpga chip ?
2015-08-27T23:28:05 < qyx_> and how do your atmegas communicate?
2015-08-27T23:28:16 < qyx_> you have to program them, the same apply to an fpga
2015-08-27T23:28:44 < Yoduza> program via usb ? :D
2015-08-27T23:28:46 < zyp> Yoduza, on the previous fpga board I made, I have it attached to the FSMC of an STM32F4
2015-08-27T23:29:32 < zyp> http://bin.jvnv.net/f/v0OjW.JPG <- I made the green board here, it's plugged into the FSMC headers of a generic STM32 devboard
2015-08-27T23:33:46 < Yoduza> cool
2015-08-27T23:34:49 < zyp> I'm still not sure what you were asking though, I'm suspecting you don't understand the nature of an fpga
2015-08-27T23:35:31 < qyx_> my next innovation will be 74xx btc miner
2015-08-27T23:35:37 < zyp> an fpga is fully configurable, so if you want SPI or I2C functionality on it, you just add an SPI or I2C core
2015-08-27T23:36:07 < Yoduza> Yes. I don't understand. Describe, please how fpga optimise "on the fly".
2015-08-27T23:36:56 < zyp> they don't, that doesn't make sense.
2015-08-27T23:37:37 < zyp> the thing is, an fpga is not a cpu, it's not comparable to a cpu
2015-08-27T23:38:39 < zyp> an fpga is a pile of simple building blocks, i.e. gates and lookup tables
2015-08-27T23:38:51 < zyp> with configurable interconnects
2015-08-27T23:40:07 < zyp> by configurating how they interconnect, you can make logic chips, just like how traditional ICs are built from a bunch of interconnected transistors
2015-08-27T23:41:07 < Yoduza> cool
2015-08-27T23:41:54 < zyp> this means that you can configure an fpga to do some specific thing, and since all gates work in parallel, they can do it pretty efficiently
2015-08-27T23:42:12 < zyp> and this is completely different to a cpu that does one instruction at a time
2015-08-27T23:42:50 < zyp> if you need SPI on an FPGA, you configure part of the FPGA to handle SPI communication, it's as simple as that
2015-08-27T23:44:06 < Yoduza> what about refresh rate on the pins of chip ? Is it comfortable for emulate sram access ?
2015-08-27T23:44:43 < zyp> depends
2015-08-27T23:45:11 < zyp> if you're emulating sram, I think end to end latency is a bigger bottleneck than IO speed

2015-08-28T00:06:21 < zyp> remember that power is voltage squared, so 2x voltage is 4x power, which gives you the conventional 6dB

2015-08-28T00:15:00 < Yoduza> *that
2015-08-28T00:16:33 < __rob> so presumably its just to increase output power for the coaxial cable ?
2015-08-28T00:16:53 < __rob> and the other end has some kind of AGC so it will fix the amplitude back to the specifciation
2015-08-28T00:17:21 < mtbg> well
2015-08-28T00:17:49 < mtbg> considering that raw video signal is very amplitude-sensitive
2015-08-28T00:18:21 < mtbg> I would guess that these amplifiers are to regenerate the signal after splitters

2015-08-28T00:25:05 < __rob> only reason I can see is that the opamps in these things have a small input voltage range (less than the Vp-p of a typical video signal)
2015-08-28T00:25:27 < __rob> so your expected to output 1/2 the output level from the dac to the op amp

2015-08-28T00:31:49 < BrainDamage> especially the bottom hand
2015-08-28T00:32:16 < mtbg> but, you are feeding it into 75 ohm coaxial cable and therefore need 75 ohm resistor in series with it
2015-08-28T00:32:25 < mtbg> the device also has 75 ohm resistor

2015-08-28T01:29:00 < bvernoux> upgrdman, 16bits could be interesting only if price is really lower (and for big quantity) vs cortex Mx 32bits MCU
2015-08-28T01:29:34 < bvernoux> for low power MCU i was checking MSP432 with M4F and it's very expensive
2015-08-28T01:29:54 < bvernoux> it's ultra low power but ultra expensive ;)

2015-08-28T01:42:43 < upgrdman> bvernoux, but what about power per watt? (genuine question) for example, will an f0 underclocked (so it performs like a 16bit mcu) draw more or less power than the 16bit mcu?
2015-08-28T01:43:36 < upgrdman> bvernoux, $0.40 - $0.60 in bulk for a small stm32f0. how much are msp's in bulk?
2015-08-28T01:45:47 < bvernoux> yes stm32f0 is very interesting at this price point
2015-08-28T01:45:56 < bvernoux> but i doubt it can be compared with msp432

2015-08-28T03:47:11 < dongs> Love it but took a while to fix color conflicts and to find a system theme which wasn't generally ugly yet allowed reading button labels in Eclipse. Still have one where I can't highlight some dialog text (like the find/replace dialog) making changes in selections problematic. I can highlight dialog text using the GTK theme. - See more at: https://marketplace.eclipse.org/content/eclipse-moonrise-ui-theme#sthash.GTP8Im4X.dpuf

2015-08-28T03:47:47 < dongs> Bummer, the screenshots look awesome. Unfortunately, this theme doesn't seem to handle C (Eclipse CDT) very well. Function calls and variable assignments are black-on-dark-grey and it just doesn't work. Activating this theme also makes other Eclipse themed elements a little funky, but I get the impression that Eclipse's UI as a whole suffers from this -- it's not the fault of this theme. - See more at: https://marketplace.eclipse.org/content/eclipse-moonrise-ui-theme

2015-08-28T04:11:19 < Roklobsta> excatly, you need the stupid app to do that 20% shutdown shit.

2015-08-28T04:12:44 < dongs> you can do 'critical battery action' power thing
2015-08-28T04:12:45 < dongs> under advanced

2015-08-28T04:12:55 < zyp> http://bin.jvnv.net/f/sfsbQ.png <- I bought some random shit and plugged it in, and OS X gives me the options to shut down after a given running time, at a given time remaining or at a given percentage remaining

To be clear, we're not the first to help find and locate lost items, but we are when it comes to our unparalleled range of 500 feet.  Imagine being able to track anything from 8 houses down the street?  It is the world's first compact Bluetooth tracker that reaches this huge distance!
2015-08-28T05:13:47 < dongs> This is achieved through a developed antenna combined with our propietary software that reaches this incredible range and we are excited to say it's built into StoneTether.

2015-08-28T05:54:17 < johntramp> hi,  I have 2 machines running the same OS, building the same firmware (same git hash from clean repositories), using the same compiler (arm-none-eabi-gcc (Arch Repository) 5.2.0), but they are creating different binaries, one which is bricking the microcontroller, and the other is running as expected.   Have you guys any advice how I can figure out what is going on?
2015-08-28T05:56:39 < johntramp> the map files produced on the two machines are very different
2015-08-28T05:57:20 -!- phantoxeD [destroy@a89-152-21-144.cpe.netcabo.pt] has quit [Read error: Connection reset by peer]
2015-08-28T05:57:31 < upgrdman> if the code, compiler AND all libs are 100% same, the output should be 100% the same
2015-08-28T05:57:35 < upgrdman> so check your libs
2015-08-28T05:57:42 < upgrdman> and makefile
2015-08-28T06:00:02 -!- phantoxeD [destroy@a89-152-21-144.cpe.netcabo.pt] has joined ##stm32
2015-08-28T06:00:45 < johntramp> yes that is what I expected, but as everything is controlled by git, checked out to the same hash as well as all submodules, I can't see how they can differ
2015-08-28T06:03:39 < upgrdman> not trying to be a dick, but something is different. maybe not something in your repo, but something.
2015-08-28T06:03:52 < upgrdman> see if the code is linking against anything not in the repo
2015-08-28T06:04:01 < upgrdman> e.g. math lib, stm lib, etc.

2015-08-28T06:21:12 < upgrdman> moar chatz plz
2015-08-28T06:21:12 < johntramp> yeah I hear you, but have no idea what is left.... all arm-none-eabi* are the exact same, both are 64bit machines, I just recloned the repositories to new locations and still can't get them to match
2015-08-28T06:21:43 < upgrdman> did you hash every file in your toolchain and compare?
2015-08-28T06:22:21 < johntramp> and the fact one of the binaries is bricking controllers seems very odd to me
2015-08-28T06:22:29 < upgrdman> agreed
2015-08-28T06:22:31 < johntramp> yes, not one of the object files matches
2015-08-28T06:22:47 < johntramp> maybe I need to make a helloworld app to compare
2015-08-28T06:22:58 < upgrdman> no, not the object files. hash every file involving in CREATING those object files
2015-08-28T06:23:15 < johntramp> ah, sure I can do that
2015-08-28T06:23:23 < johntramp> i am confident they are though because that is what git does
2015-08-28T06:23:23 < upgrdman> compare hashes for you gcc, ld, etc. and hash for every .h and .c in any libs you use, etc.
2015-08-28T06:23:55 < upgrdman> no. fuck what's in your repo. look EVERYWHERE except the repo
2015-08-28T06:24:04 < upgrdman> check your compiler, linker. hash them.
2015-08-28T06:24:13 < upgrdman> something is different
2015-08-28T06:25:05 < johntramp> /usr/bin/arm-none-eabi-* are all OK

2015-08-28T16:24:39 < dongs> With regard to the video clip yesterday showing the 720p footage @10fps, we are concerned that unscrupulous members of the press would publish this as finished Zano footage, especially as we had a lot of contact with members of the press yesterday trying to jump on the back of the BBC article. For this reason the clip will remain private. I hope you can understand why we have done this.
2015-08-28T16:24:45 < dongs> What I can do is edit the video and water mark it saying "720P 10FPS PREVIEW FOOTAGE" just to ensure the above doesn't happen.
2015-08-28T16:24:49 < dongs> Can you give me a little time, I will get one of the guys to add the water mark and we can then share it.

2015-08-28T17:54:50 < dongs> oo
2015-08-28T17:54:53 < dongs> mdk516 just released
2015-08-28T17:54:55 < dongs> grabbing
2015-08-28T17:54:57 < upgrdman_> no kidding. super pro lib.

2015-08-28T17:56:05 < stukdev> dongs: like coocox + cube, can you add two cdc device? so having 2 virtual serial port?
2015-08-28T17:56:35 < dongs> i know you can have multiple usb shits like hid+cdc
2015-08-28T17:56:37 < dongs> i never tried two ports
2015-08-28T17:56:40 < dongs> probably
2015-08-28T17:57:30 < stukdev> k thanks
2015-08-28T17:57:58 < dongs> The ARM Compiler 5.05u2 must be used for ARM7, ARM9 and Cortex-R4 processor based targets due to a regression in ARM Compiler 5.06. This defect will be fixed in MDK Version 5.17.
2015-08-28T17:58:01 < dongs> haha
2015-08-28T17:58:09 < dongs> ARM Compiler 5.06 (default for Cortex-M targets) which includes support for STM32L4 Series.

2015-08-28T18:01:33 < dongs> Improved: Project build now takes advantage of systems that have multiple processors or multiple-core processors. Additional build processes are created to utilize the available processors and therefore drastically reduce the overall built time. µVision can process these builds simultaneously, and therefore overall build time is reduced.
2015-08-28T18:01:38 < dongs> yay!

2015-08-28T18:09:07 < karlp> seems to only be to older revisions, if I read an2606 rev22 properly.
2015-08-28T18:09:15 < karlp> where are the revisions in the refman or the datasheet?
2015-08-28T18:09:30 < karlp> looks like rev4 on the disco board.
2015-08-28T18:11:24 < karlp> DBGMCU_IDCODE in the ref man talks about "Cut 1.x",  cut 2.x and "cut x.1"
2015-08-28T18:11:39 < karlp> instead of the regular x,y,z,a,b type rev numbers in normal ref mans.
2015-08-28T18:15:00 < karlp> heh, so v9 bootloader supported can and spi, back in rev Y devices.  v10 just drops support for can.  "no more workaround required! the feature is just not available at all!" fuck fixing it!
2015-08-28T18:15:56 < talsit> is it possible to design a multi-board project in alitum? as in, 2 PCB with mezzaniene connectors between them? and test for clearances?
2015-08-28T18:16:23 < dongs> talsit: no but you can export pcb1 as .stl or wahtever and load it as 3d body into pcb2
2015-08-28T18:16:26 < dongs> and test for clearacens
2015-08-28T18:16:41 < talsit> right... ok
2015-08-28T18:16:47 < talsit> that would ... work, i guess
2015-08-28T18:16:57 < dongs> it does, i've used it to do exactly that
2015-08-28T18:17:24 < talsit> no doubt
2015-08-28T18:19:27 < karlp> wow, errata sheet is not even consistent with itself. headings say one thing, body says another
2015-08-28T18:20:50 < karlp> oh, and now in rev4, can/spi is enabled again. sounds like a difficult childhood internally at st for the l4

2015-08-28T19:11:21 < Steffann_> maybe it was called update(); before Tectu
2015-08-28T19:12:09 < Tectu> you know the best part?
2015-08-28T19:12:09 < Steffann_> then someone fixed that except for the comment.. you never know
2015-08-28T19:12:24 < Tectu> updateModel() is a private method doing nothing but calling    mModel->update()
2015-08-28T19:12:39 < Steffann_> the best part: you wrote it?

2015-08-28T19:47:16 < upgrdman_> and Tycho
2015-08-28T19:47:20 < emeb> +1
2015-08-28T19:48:44 < karlp> upgrdman_: half done is so you can start crunching the data straight away, instead of waiting for the complete transfer then starting crunching
2015-08-28T19:49:03 < upgrdman_> ah that makes sense.
2015-08-28T19:49:30 < Laurenceb__> more like so you know the transfer is in the other half
2015-08-28T19:49:40 < zyp> especially makes sense in circular mode, when it'll start overwriting first half after filling second half
2015-08-28T19:49:41 < Laurenceb__> so you can touch the data without worrying about corruption
2015-08-28T19:49:43 < zyp> and other way around
2015-08-28T19:49:48 < emeb> I use circular DMA with HT / TC to get double-buffer functionality w/o the trouble of setting up two buffers.
2015-08-28T19:49:56 < Laurenceb__> me too
2015-08-28T19:50:00 < karlp> ^^ all of those things :)
2015-08-28T19:50:03 < Laurenceb__> for GPS on balloon stuff
2015-08-28T19:50:40 < emeb> kinda makes me wonder why they bothered even including true double-buffer mode.
2015-08-28T19:50:41 < upgrdman_> ht tc?
2015-08-28T19:50:53 < emeb> half-transfer / transfer-complete
2015-08-28T19:50:58 < zyp> emeb, because it has a completely different usecase
2015-08-28T19:51:11 < emeb> which is?
2015-08-28T19:51:21 < zyp> double buffer mode allows you to chain any length of buffers by replacing the inactive buffer pointer
2015-08-28T19:51:36 < emeb> ah. makes sense.
2015-08-28T19:51:42 < zyp> so it's more a mechanism of chaining buffers
2015-08-28T19:51:51 < emeb> if you're modifying the DMA on the fly
2015-08-28T19:52:27 < zyp> the RM documents how you do this, so that's how it's intended
2015-08-28T19:52:46  * emeb has peephole optimizer on when reading the RM

2015-08-28T22:32:39 < chris_99> (i was thinking i could just stream data via a virtual serial device, but it'd be nicer to use an actual audio interface)
2015-08-28T22:45:40 < zyp> just do usb audio
2015-08-28T22:46:30 < zyp> you'll have to set up a bunch of descriptors, and then it's just a matter of streaming data over an isochronous pipe

2015-08-28T23:28:38 < Rickta59> upgrdman_: you might want to use something different if you are talking to a chip that is extremely slow, you can set the stop bits to 3 to give it time to catch
2015-08-28T23:28:47 < Rickta59> up
2015-08-28T23:29:03 < upgrdman_> ya i get that
2015-08-28T23:29:12 < upgrdman_> but why would anyone ever want HALF bits of stop time
2015-08-28T23:29:17 < upgrdman_> integer fine, but half?!
2015-08-28T23:29:31 < Rickta59> can't say i ever used half bits
2015-08-28T23:29:36 < upgrdman_> good.
2015-08-28T23:29:59 < Rickta59> however you would be able to the where one frame ends and the next begins
2015-08-28T23:31:43 < Rickta59> be able to see where

2015-08-29T00:26:39 < karlp> upgrdman_: what IDE were you using that rendered the image? that sounds neat
2015-08-29T00:27:07 < karlp> upgrdman_: half/1.5 stop bits is for smart card shitz
2015-08-29T00:27:16 < karlp> it's "required"
2015-08-29T00:28:08 < zyp> idk, I'd say that sounds annoying
2015-08-29T00:28:42 < karlp> probably has a few good case, and a lot of shit cases :)
2015-08-29T00:29:00 < zyp> generally I don't like when comments distracts from the actual code
2015-08-29T00:29:21 < karlp> I would presume it would only render when you're done ctrl-space or somethign to pop up the documentation viewer,
2015-08-29T00:29:30 < karlp> not rendered inline when just editing the source.
2015-08-29T00:30:16 < zyp> I used to work with a guy who used figlet to make headers for sections in source files
2015-08-29T00:30:24 < zyp> that was annoying as fuck
2015-08-29T00:32:07 < karlp> upgrdman_: if you want intellij, best option is to get intellij, not try and find a theme for eclipse  by the way :)
2015-08-29T00:32:11 < upgrdman_> karlp, that renders <img> ?
2015-08-29T00:32:29 < karlp> you said it's easy in java, yeah,
2015-08-29T00:32:36 < upgrdman_> ya
2015-08-29T00:32:45 < upgrdman_> javadoc accepts html
2015-08-29T00:32:49 < karlp> I know things will render it when you generate docs to static, but I'd never seen an IDE render them inline
2015-08-29T00:32:50 < upgrdman_> so you do /**
2015-08-29T00:32:57 < upgrdman_> * <img ...>
2015-08-29T00:32:59 < upgrdman_> */
2015-08-29T00:33:11 < upgrdman_> and then hover over it, and the javadoc popup will render it
2015-08-29T00:33:25 < karlp> in which ide was that? eclipse?
2015-08-29T00:33:27 < upgrdman_> ya not in line, but if you hover
2015-08-29T00:33:43 < upgrdman_> karlp, i dont think i posted a pic? did i? what?
2015-08-29T00:34:18 < karlp> no, I was just asking if it did, and what ide it was :)
2015-08-29T00:35:26 < upgrdman_> karlp, here's what it looks like:
2015-08-29T00:35:27 < upgrdman_> https://www.eclipse.org/forums/index.php/fa/21510/0/

2015-08-29T00:37:29 < upgrdman_> like this http://snag.gy/viSiA.jpg
2015-08-29T00:37:42 < karlp> heh, that's just silly :)
2015-08-29T00:38:08 < karlp> but that's really just img support
2015-08-29T00:38:17 < upgrdman_> but ya... intellij. im somewhat intrigued by it. but it doesn't support c.
2015-08-29T00:38:22 < karlp> clion does :)
2015-08-29T00:38:28 < upgrdman_> and clion is $100
2015-08-29T00:38:28 < karlp> but only for cmake projects so far.
2015-08-29T00:38:38 < karlp> I'm pretty tempted to buy it already
2015-08-29T00:39:17 < upgrdman_> its also secret sauce iirc, which is a bit sad but understandable
2015-08-29T00:40:08 < karlp> yeah, I've used pay intellij for java work in the past and it's fucking so much more amazeballs than eclipse
2015-08-29T00:40:33 < upgrdman_> well ya.
2015-08-29T00:40:37 < karlp> Im using pycharm now at work, tempted to buy it too, to add in the javascript and css editing.
2015-08-29T00:40:49 < upgrdman_> i only "like" eclipse because im used to all of its annoyances
2015-08-29T00:41:00 < karlp> if they can sort out makefiles and cross comppile in clion I'm all over that shit
2015-08-29T00:41:12 < upgrdman_> any idea if they plan to?
2015-08-29T00:41:33 < karlp> oh, yeah, it's like the top three issues in the tracker, "makefilez plz" "cross plz"
2015-08-29T00:41:40 < upgrdman_> cool
2015-08-29T00:41:54 < karlp> they referred to some survey to plan out support, and osmehow came to the conclusion that cmake was more important first.
2015-08-29T00:42:10 < karlp> it's maybe a good choice as they use the cmake file as the project file itself.
2015-08-29T00:42:19 < upgrdman_> must have interviewed the zano guys
2015-08-29T00:42:37 < upgrdman_> cmake all the things
2015-08-29T00:47:03 < Rickta59> i really hate visual studio but i used to use it ( like 6 years ago ) for its javascript support, it was actually great
2015-08-29T00:47:21 < Rickta59> i'd like to find something decent to do javascript with html for linux

2015-08-29T00:49:07 < karlp> (i ended up doing more lua and js/html with clion than c)

2015-08-29T02:57:35 < artag> organisation is overrrated. I'm down to a keyboard-sized space on mine now
2015-08-29T02:57:59 < zyp> I know I bought some nrf51 modules some time, and I'm pretty sure they are somewhere on my desk, but I have no idea where
2015-08-29T02:58:32 < zyp> it's around a year since I bought them
2015-08-29T02:59:26 < zyp> oh, found them
2015-08-29T02:59:41 < zyp> they were right behind my keyboard
2015-08-29T02:59:55 < zyp> complaining on irc obviously helps
2015-08-29T03:01:52 < zyp> good thing I'm planning to move in a couple of months
2015-08-29T03:02:26 < artag> won't help. You'll just stick it all in a box and then slowly move it back to the desk
2015-08-29T03:02:50 < artag> the desk will be clear for a while but everything you want will have you searching that box
2015-08-29T03:02:56 < zyp> I'll never find anything again if I do that
2015-08-29T03:03:27 < zyp> I'm planning on actually organizing shit when packing down and making a list of what went into which box
2015-08-29T03:04:40 < upgrdman> i use some akro mils organizers. love them
2015-08-29T03:04:43 < upgrdman> like this:

2015-08-29T03:07:23 < zyp> yeah, I should probably get some
2015-08-29T03:07:42 < zyp> how is the quality on those?
2015-08-29T03:08:00 < upgrdman> excellent for the price

2015-08-29T03:10:20 < zyp> okay, so they don't attach to each other
2015-08-29T03:10:21 < upgrdman> i wall mount mine
2015-08-29T03:10:25 < upgrdman> no
2015-08-29T03:10:45 < upgrdman> they just have grooves so one can sit on another and only slide off if you kinda try
2015-08-29T03:11:07 < upgrdman> theres other configs too, with bigger drawers etc
2015-08-29T03:11:14 < upgrdman> search amazon for Akro Mils

2015-08-29T03:35:44 < upgrdman> dongs, they ever have a fucking MP3 on their website so you can masturbase to the sound of the keyboard before buying one
2015-08-29T03:35:49 < dongs> oh fuck yes
2015-08-29T03:35:50 < dongs> link
2015-08-29T03:35:53 < upgrdman> dongs, one sec
2015-08-29T03:36:04 < dongs> is it tenkeyless
2015-08-29T03:36:16 < upgrdman> http://www.daskeyboard.com/daskeyboard-4-professional/
2015-08-29T03:36:25 < upgrdman> NO! i REQUIRE 10 key
2015-08-29T03:36:36 < upgrdman> mp3 is about 30% down the page
2015-08-29T03:36:52 < dongs> ya found
2015-08-29T03:36:59 < dongs> oh fuck dude get out
2015-08-29T03:37:01 < upgrdman> they make a version without 10key for all the hipster faggots
2015-08-29T03:37:03 < dongs> i have a filco that clicks like that
2015-08-29T03:37:10 < dongs> its in teh fucking storage
2015-08-29T03:37:18 < upgrdman> you dont like it?
2015-08-29T03:37:22 < zyp> do they only have that layout with the shitty enter button?
2015-08-29T03:37:34 < upgrdman> i also have a model m but wanted something black and with media and win key
2015-08-29T03:37:50 < upgrdman> usb3 hub was just an added boner
2015-08-29T03:38:07 < upgrdman> zyp, WAT!? you like the gay ass L shaped enter keys?
2015-08-29T03:38:09 < karlp> I need to check how to ge ta us keyboard to work in icelandic agan.
2015-08-29T03:38:27 < karlp> but yeah, I've got really like the volumn up / down keys on my keyboard at work.
2015-08-29T03:38:49 < zyp> upgrdman, idk about L-shaped, mine is q-shaped
2015-08-29T03:39:00 < upgrdman> err ya
2015-08-29T03:39:03 < upgrdman> upside down L
2015-08-29T03:39:16 < zyp> I've been typing on keyboards with a two-row enter button for all my life, I refuse to change that now
2015-08-29T03:39:27 < upgrdman> you bring me great sadness
2015-08-29T03:39:32 < upgrdman> but to each their own
2015-08-29T03:40:09 < zyp> need room for my æøå's
2015-08-29T03:41:31 < karlp> dongs: the daskeyboard website has audio of clicky typing for blue vs brown
2015-08-29T03:41:38 < upgrdman> gæy
2015-08-29T03:41:49 < upgrdman> karlp, he found it
2015-08-29T03:41:54 < dongs> karlp: iknow
2015-08-29T03:43:36 < karlp> yeah, I need more keys than that has.
2015-08-29T03:43:44 < karlp> my stupid alphabet has more letters
2015-08-29T03:44:07 < karlp> it says they have a 105key norwegian, that would probably work
2015-08-29T03:45:08 < karlp> what the hell is a mac specifc version?
2015-08-29T03:45:11 < zyp> https://www.youtube.com/watch?v=f488uJAQgmw
2015-08-29T03:46:00 < zyp> karlp, where do you see that?
2015-08-29T03:47:44 < dongs> zyp perks up cuz mac is mentioned
2015-08-29T03:47:49 < dongs> so he can replace his APPLE MA GIC KEYBOARD
2015-08-29T03:47:58 < zyp> no, it was the norwegian part I was interested in
2015-08-29T03:48:43 < upgrdman> karlp, macfag version just has the apple command logo instead of the win key logo
2015-08-29T03:48:53 < upgrdman> i bought the win version and use it on a mac. works fine.
2015-08-29T03:49:24 < zyp> upgrdman, they've probably swapped the alt and win/cmd buttons as well
2015-08-29T03:49:39 < upgrdman> true
2015-08-29T03:49:45 < upgrdman> the win key works as cmd for me
2015-08-29T03:50:04 < zyp> windows keyboards have ctrl, win, alt, space, mac keyboards have ctrl, alt, cmd, space
2015-08-29T03:50:12 < upgrdman> ya
2015-08-29T03:52:47 < dongs> more reasons why macs are garbage

2015-08-29T03:53:55 < karlp> let's me upload a graphic with my own custom keys all over it. wooee
2015-08-29T03:54:20 < karlp> zyp: ah, I hadn't realised the alt-cmd swappage, thanks.
2015-08-29T03:54:35 < zyp> upgrdman, well, they are the same key code
2015-08-29T03:54:48 < zyp> HID defines it as left and right «GUI key»
2015-08-29T03:54:57 < dongs> so hold on
2015-08-29T03:54:59 < dongs> for $150
2015-08-29T03:55:00 < karlp> this page says 105 key for uk, no, de layouts: http://www.daskeyboard.com/daskeyboard-4-professional/#/awesome-products
2015-08-29T03:55:04 < dongs> they will put any  text on keys?
2015-08-29T03:55:14 < karlp> seems that way
2015-08-29T03:55:18 < karlp> and any colour keycaps too
2015-08-29T03:55:20 < upgrdman> dickbutt ftw
2015-08-29T03:55:29 < dongs> yeah totally adding dickbutt to windows key
2015-08-29T03:55:31 < karlp> but no usb3 hub or proper media keys, just fn- shit
2015-08-29T03:55:39 < dongs> fuck media shit
2015-08-29T03:55:55 < zyp> dongs, you can just buy custom keycaps elsewhere

2015-08-29T03:56:11 < zyp> lots of places making custom caps for cherry mx keys
2015-08-29T03:56:19 < karlp> well, that place sells keyboards and just caps
2015-08-29T03:56:27 < karlp> but you have to have the cherry mx keyboard first.
2015-08-29T03:57:53 < upgrdman> need to pop your cherry

2015-08-29T04:05:59 < zyp> upgrdman, haha, I'm looking at those drawer racks now
2015-08-29T04:06:12 < upgrdman> k
2015-08-29T04:06:17 < zyp> I suspected they wouldn't ship it to norway, but they would
2015-08-29T04:06:17 < upgrdman> liking them?
2015-08-29T04:06:26 < zyp> if I pay $94 for shipping
2015-08-29T04:06:35 < upgrdman> should. it's not like secret us military stuff
2015-08-29T04:06:38 < upgrdman> o lol
2015-08-29T04:07:01 < upgrdman> is there an amazon.norway?
2015-08-29T04:08:04 < zyp> sadly not
2015-08-29T04:08:32 < upgrdman> .sweden or .finland? surely you ice niggers have access to amazon?
2015-08-29T04:08:40 < zyp> not locally
2015-08-29T04:08:45 < upgrdman> :(
2015-08-29T04:08:51 < zyp> closest would be .de or .uk
2015-08-29T04:09:17 < zyp> hmm, looks like there are ebay sellers with free shipping to norway for $31 though
2015-08-29T04:09:23 < zyp> for that 8x8 rack
2015-08-29T04:09:35 < upgrdman> neat
2015-08-29T04:09:51 < upgrdman> hopefuly they pack it in a box ;)
2015-08-29T04:09:57 < zyp> haha
2015-08-29T04:10:02 < upgrdman> bubble envelope might not fare too well :)
2015-08-29T04:11:01 < zyp> oh, wait, fuck
2015-08-29T04:11:06 < zyp> that was free shipping to the US
2015-08-29T04:12:03 < zyp> cheapest shipped to norway seems to be $75
2015-08-29T04:12:05 < upgrdman> bummer
2015-08-29T04:12:22 < upgrdman> there's got to be some scandenavian maker of shits like that
2015-08-29T04:12:37 < upgrdman> poke your local electronics nerds
2015-08-29T04:13:02 < zyp> most of what I've seen is shitty quality that breaks
2015-08-29T04:13:27 < upgrdman> :(
2015-08-29T04:14:36 < upgrdman> do mouser / digikey / equiv have a scanda warehouse? they carry akro mills products.
2015-08-29T04:14:49 < zyp> oh, fair point
2015-08-29T04:14:56 < zyp> they do free shipping to norway
2015-08-29T04:16:05 < zyp> can't see it in their inventory though
2015-08-29T04:16:09 < dongs> digikey has no international warehouse.
2015-08-29T04:16:13 < dongs> they just ship from texas or wahtever.
2015-08-29T04:16:23 < dongs> neither does mouser
2015-08-29T04:16:33 < dongs> they have some sales offices in HK, thats what emails me when  iplace orders
2015-08-29T04:16:49 < dongs> they probly have some local shit in eurotrash too
2015-08-29T04:16:52 < zyp> yeah, mouser has an office in sweden
2015-08-29T04:16:56 < zyp> not sure about digikey
2015-08-29T04:17:33 < upgrdman> shit. i was wrong.
2015-08-29T04:17:34 < zyp> they beat norwegian webstores on shipping times anyway
2015-08-29T04:17:44 < upgrdman> i could have sworn i saw akro mils stuff on mouser
2015-08-29T04:17:59 < karlp> mouser emails me and calls from .se, but it all still ships from us.
2015-08-29T04:19:09 < upgrdman> seems akro mils only has distributors in us and canadia

2015-08-29T04:40:17 < upgrdman> 32 000 000
2015-08-29T04:40:51 < upgrdman> like engineering notation on a calculator
2015-08-29T04:41:00 < dongs> just do 32*1000*1000 if you wanna make it clear
2015-08-29T04:41:06 < dongs> compiler will make it constant anyway.
2015-08-29T04:41:27 < upgrdman> :/
2015-08-29T04:41:46 < zyp> 32e6 is a float literal, which will then be casted to an integer if you try that
2015-08-29T04:42:21 < zyp> or a double literal, I guess
2015-08-29T04:43:05 < zyp> I'm not sure if a float literal can even represent 32e6 accurately, I think that's larger than the mantissa
2015-08-29T04:43:28 < zyp> hmm, should be good
2015-08-29T04:43:38 < zyp> since 32 is 2**n
2015-08-29T04:43:51 < upgrdman> well 32 was just a random thought
2015-08-29T04:44:13 < upgrdman> might do something gay like 123e4
2015-08-29T04:44:46 < zyp> bad idea in general
2015-08-29T04:45:20 < upgrdman> k
2015-08-29T04:45:43 < zyp> in c++11 you could make a user defined literal for integers with scientific notation
2015-08-29T04:46:24 < zyp> user defined literals seems neat, but I haven't found a reason to use them anywhere yet

2015-08-29T05:01:43 < zyp> hmm
2015-08-29T05:02:14 < zyp> testing radio code on this stuff is gonna be annoying
2015-08-29T05:02:43 < zyp> it's kinda hard to test sender and receiver code separately
2015-08-29T05:03:12 < zyp> maybe I can set up bladerf as a receiver and finally use it for something
2015-08-29T05:03:23 < Roklobsta> mtbg: try 2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2*2

2015-08-29T05:22:14 < emeb> ah - with that nrf thing?
2015-08-29T05:22:18 < zyp> if you've got any advice on protocol design, I'd be happy to hear it

2015-08-29T05:23:05 < zyp> got any advice on super compact pcb design? :p
2015-08-29T05:23:23 < dongs> zyp is gonna dickstart the next BLE location dongle
2015-08-29T05:23:30 < dongs> with 500 meter range
2015-08-29T05:23:33 < zyp> would chip antenna make sense if size is priority?
2015-08-29T05:24:05 < zyp> dongs, nah, not gonna do BLE
2015-08-29T05:24:06 < emeb> AFAIK chip antennas don't give the best performance. If size is priority though then it's a good compromise.
2015-08-29T05:24:14 < zyp> kinda tempted to write a BLE stack though
2015-08-29T05:24:28 < Roklobsta> zyp: you gonna try and reinvent the compact-but-routable-data-frame-for-IoT wheel?
2015-08-29T05:25:01 < zyp> not related to IoT
2015-08-29T05:25:38 < zyp> and I don't think I care about routing, I think a simple star network with a single master is good enough for what I want to do
2015-08-29T05:25:48 < Roklobsta> zyp: look at protocols that already exist, adapt them for your need and avoid their mistakes.
2015-08-29T05:26:09 < Roklobsta> maybe to a token ring with broadcasts.
2015-08-29T05:26:12 < Roklobsta> do
2015-08-29T05:26:38 < zyp> heh
2015-08-29T05:26:43 < Roklobsta> not token ring, TDMA.
2015-08-29T05:27:03 < Roklobsta> time slots based on address.  what is the max addressable devices?  256?
2015-08-29T05:27:10 < zyp> undecided
2015-08-29T05:27:25 < dongs> zano swarm 2.0
2015-08-29T05:27:38 < zyp> but yeah, I'm thinking of a «speak only when spoken to» policy for slaves
2015-08-29T05:27:47 < zyp> i.e. fixed reply slot after command slot
2015-08-29T05:27:59 < emeb> It's amusing to me that 802.11 has PCF and DCF and AFAIK no one uses PCF.
2015-08-29T05:28:40 < emeb> seems like assigned timeslots would be a good thing.
2015-08-29T05:28:45 < upgrdman> googled PCF... prostate cancer foundation
2015-08-29T05:29:03 < emeb> point coordinating function vs distributed coordinating function.
2015-08-29T05:29:18 < emeb> basically the AP sets up a TDMA system
2015-08-29T05:29:18 < Roklobsta> emeb: i think mikrotiks nv2 protocol does that
2015-08-29T05:29:39 < Roklobsta> yep nv2 does that as do ubuquiti radios
2015-08-29T05:29:44 < zyp> yeah
2015-08-29T05:29:52 < zyp> it seems common in carrier grade wlan
2015-08-29T05:31:03 < emeb> When I was working at ISIL on the Prism chipsets we knew about PCF but nobody bothered to code it up.
2015-08-29T05:31:04 < Roklobsta> to the point where the masters use GPS PPS.
2015-08-29T05:31:19 < Roklobsta> emeb: you spent time in Syria eh?
2015-08-29T05:31:38 < emeb> hrhr
2015-08-29T05:32:22 < zyp> IIRC BLE have pretty strict timeslots, so I think the radio in nrf51 have hardware support for timing the reply transmission
2015-08-29T05:32:41 < Roklobsta> zyp: how will slaves notify master they are on or exist?
2015-08-29T05:33:35 < zyp> unsure yet
2015-08-29T05:34:16 < emeb> there's usually a contention timeslot for joining the network, no?
2015-08-29T05:39:37 < zyp> master should know which slaves to message/poll, so I guess I just need a mechanism for master learning slave addrs
2015-08-29T05:40:58 < zyp> I want slaves to have globally unique addrs so they won't have to be assigned a locally unique addr when joining a network
2015-08-29T05:41:06 < upgrdman> how string? ns's?
2015-08-29T05:41:09 < upgrdman> strict
2015-08-29T05:41:15 < zyp> strict?
2015-08-29T05:41:39 < upgrdman> <zyp> IIRC BLE have pretty strict timeslots
2015-08-29T05:41:42 < upgrdman> how strict
2015-08-29T05:41:53 < upgrdman> sub us?
2015-08-29T05:42:12 < zyp> I don't remember, there's a year and a half since I read through the BLE specs
2015-08-29T05:42:17 < upgrdman> ah k
2015-08-29T05:44:33 < zyp> looks like the interframing spacing register in the nrf radio have us resolution, so I guess within a few us

2015-08-29T05:54:41 < Roklobsta> zyp: ah ok, simple stuff.  well, i was just thinking try implement an error correcting code for the frames, not just error detection.
2015-08-29T05:54:54 < Roklobsta> you might get some extra range out of it.
2015-08-29T05:55:50 < Roklobsta> plus less retries
2015-08-29T05:55:52 < zyp> I don't think range will be an issue
2015-08-29T05:56:52 < zyp> and I'm not sure a few lost packages will be a concern either, for periodic updates, it's probably okay waiting for the next update
2015-08-29T06:00:59 < owl-v-> omg omg omg!  I got a new Macbook PRO!
2015-08-29T06:03:11 < zyp> time to start doing pro stuff then!

2015-08-29T06:07:37 < Roklobsta> the antiglare will delaminate in 2 years
2015-08-29T06:08:14 < GargantuaSauce> and the battery will be long gone by then anyway
2015-08-29T06:09:39 < zyp> heh
2015-08-29T06:10:00 < zyp> is that even a known problem?

2015-08-29T06:11:33 < zyp> my MBP from 2011 doesn't have any mechanical problems and the battery still packs hours of use
2015-08-29T06:11:53 < zyp> I think it says around 85% health or so
2015-08-29T06:12:08 < Roklobsta> owl-v-: i refer to this.  http://www.macrumors.com/2015/03/16/retina-macbook-pro-stained-coating/

2015-08-29T06:25:58 < dongs> Funny story. I accidentally typed a - symbol in a configuration value and instead of slowing down Zano sped up and up and up. Wow was it moving when it slammed into a concrete wall. I was sprinting after it and not even close, it accelerated away from me twice my speed at least. That Zano still works apart from the motor, arm, propeller that disintergrated and I can only find pieces.
2015-08-29T06:26:05 < dongs> wat

2015-08-29T06:26:44 < dongs> ivan
2015-08-29T06:27:05 < zyp> dongs, what part of it?
2015-08-29T06:28:00 < zyp> sounds reasonable that the arm breaks off from crashing into a wall, sounds reasonable that the microcontroller still runs
2015-08-29T06:28:14 < GargantuaSauce> that it flew
2015-08-29T06:28:49 < zyp> flying isn't hard, it's not crashing that's hard, and they've obviously not managed that
2015-08-29T06:29:38 < zyp> sure, just be careful with symbols
2015-08-29T06:29:54 < GargantuaSauce> yeah just wrap the headers with extern "C" {}
2015-08-29T06:30:05 < zyp> C++ does name mangling on symbols

2015-08-29T17:54:09 < emeb> IIRC it's not a true parabolic shape. They can steer the beam to a certain degree by moving the emitter around to different focal points.

2015-08-29T17:59:14 < dongs> how many things will depends on camera jpeg engine?
2015-08-29T17:59:39 < dongs> i think some may more than once.
2015-08-29T18:01:37 < Steffanx> the upcoming release will be without object trackign not?
2015-08-29T18:01:50 < mtbg> the engine depends on itself
2015-08-29T18:02:00 < dongs> object tracking, lol
2015-08-29T18:02:09 < dongs> whats it gonna track with????
2015-08-29T18:02:14 < dongs> running opencv on pic32?
2015-08-29T18:02:19 < Steffanx> yeah, why not?
2015-08-29T18:02:26 < dongs> because not
2015-08-29T18:02:30 < dongs> there's no why
2015-08-29T18:02:34 < zyp> what's this talk about compression level?
2015-08-29T18:02:40 < Steffanx> bitbang ddr3
2015-08-29T18:02:44 < dongs> zyp, camera has jpeg encoder
2015-08-29T18:02:51 < dongs> with selectable quality
2015-08-29T18:03:07 < zyp> but it's ratio from raw?
2015-08-29T18:03:11 < dongs> nope
2015-08-29T18:03:16 < dongs> you cant guarantee ratio
2015-08-29T18:03:18 < dongs> with jpeg..
2015-08-29T18:03:41 < zyp> well, I'm just wondering what bitrates they are talking here :p
2015-08-29T18:03:59 < dongs> average, i geuss
2015-08-29T18:04:12 < dongs> i'm pretty sure they wont be able to stream any frame > 30-60k
2015-08-29T18:04:25 < dongs> because thats how much buffer ram should be in STM32F205 on the wifi dickey
2015-08-29T18:04:27 < zyp> I mean, they don't mention bitrate
2015-08-29T18:05:31 < dongs> different complexity image will be different size at same jpeg quality level
2015-08-29T18:05:35 < zyp> I assumed 15:1 was a ratio vs raw
2015-08-29T18:05:41 < dongs> so you cant have constant bitrate
2015-08-29T18:06:04 < zyp> then again, how do they measure raw size? which color space?
2015-08-29T18:06:15 < Steffanx> but they have their own custom mjpeg streamer that will be super efficient.
2015-08-29T18:06:25 < Steffanx> written from scratch
2015-08-29T18:06:29 < Steffanx> in asm
2015-08-29T18:06:38 < dongs> they should have just copied ffmpeg/gstreamer from lunix
2015-08-29T18:06:44 < dongs> proven amazecode
2015-08-29T18:07:14 < kakimir> they are in hell
2015-08-29T18:07:35 < emeb> oversold, underthunk
2015-08-29T18:07:39 < zyp> if we assume 16bpp, then 1080p60 compressed 15:1 would be 8 MB/s, i.e. 128 Mb/s
2015-08-29T18:07:49 < zyp> that's pretty bad video compression :p
2015-08-29T18:08:02 < dongs> whats frame size for that?
2015-08-29T18:08:06 < dongs> for 8mb/s
2015-08-29T18:08:11 < kakimir> with bagloads of money for thailand vacation
2015-08-29T18:08:15 < dongs> 136k?
2015-08-29T18:08:18 < mtbg> mjpeg doesn't compress well, it has just keyframes
2015-08-29T18:08:43 < dongs> 136k 1920x1080.jpg woud look pretty awful anyway
2015-08-29T18:09:06 < dongs> mtbg: sure, but when you compress it in PIC32 asm, it suddenly becomes way better.
2015-08-29T18:09:26 < kakimir> what is 136K?
2015-08-29T18:09:33 < zyp> dongs, 266k
2015-08-29T18:09:34 < dongs> < zyp> if we assume 16bpp, then 1080p60 compressed 15:1 would be 8 MB/s, i.e. 128 Mb/s
2015-08-29T18:09:39 < dongs> zyp, how so
2015-08-29T18:09:40 < kakimir> why don't they have some wlan router in it
2015-08-29T18:09:43 < dongs> wasnt that p60?
2015-08-29T18:09:49 < zyp> yes?
2015-08-29T18:09:49 < kakimir> or proper bluetooth
2015-08-29T18:09:56 < dongs> 8192/60 = 133?
2015-08-29T18:10:07 < dongs> or amistoned
2015-08-29T18:10:14 < zyp> idk what you're talking about anymore
2015-08-29T18:10:36 < dongs> zyp, 8MiB/second, 60 frames per second
2015-08-29T18:10:46 < dongs> so 1 frame would be 8MiB/60, no?
2015-08-29T18:10:50 < dongs> ~average
2015-08-29T18:10:57 < zyp> oh, I meant 16 MB/s
2015-08-29T18:11:04 < zyp> my bad
2015-08-29T18:11:34 < dongs> can STM32F205 even manage 16mb/sec out of any interface on it, lol.
2015-08-29T18:11:55 < dongs> im gonna guess: no
2015-08-29T18:12:26 < emeb> dma bytewide GPIO!
2015-08-29T18:12:37 < Steffanx> but they have special custom customized fw for the f205 ..
2015-08-29T18:12:42 < zyp> well, this was the shit for saving to SD
2015-08-29T18:12:56 < zyp> they're only talking about an eight of that for wlan
2015-08-29T18:12:58 < dongs> pic runs at 200mhz, how is it going to do anything with 128mbit stream
2015-08-29T18:13:34 < dongs> never mind writing at SD card at 16meg/sec with only 400kbyte buffer
2015-08-29T18:13:51 < dongs> and thats assuming you can write to it in 1/120s second because otherwise next frame will be on the way to it
2015-08-29T18:14:04 < dongs> they're so fucked
2015-08-29T18:14:26 < zyp> wonder how fast their SD card interface is
2015-08-29T18:14:31 < dongs> its just SPI
2015-08-29T18:14:34 < dongs> pic has no sdio
2015-08-29T18:14:39 < zyp> haha
2015-08-29T18:14:41 < dongs> so like 25mhz if they're lucky?
2015-08-29T18:14:43 < mtbg> oh well
2015-08-29T18:14:44 < zyp> then it's impossible
2015-08-29T18:15:15 < zyp> even stm32f4 can only do like 12MB/s and that's with four-bit SDIO
2015-08-29T18:15:58 < zyp> IIRC it were supposed to be able to do 24MB/s, and then there's some errata that says you can only run half speed
2015-08-29T18:16:38 < Laurenceb__> do they have wifi streaming + video storage working yet?
2015-08-29T18:16:44 < zyp> and IIRC there's also some workaround where you can run the 48MHz domain at 96MHz, assuming you don't use it for usb
2015-08-29T18:16:46 < dongs> just barely streaming
2015-08-29T18:16:47 < Laurenceb__> or cant the camera do multiple streams?
2015-08-29T18:16:49 < dongs> some 10fps trash
2015-08-29T18:16:50 < Laurenceb__> ah
2015-08-29T18:16:51 < dongs> cant
2015-08-29T18:16:55 < Laurenceb__> doh
2015-08-29T18:17:06 < Laurenceb__> they need ambarella
2015-08-29T18:17:37 < Laurenceb__> or do something sensible and get a bluetooth keyfob type thing with analogue video and decent telemetry link on it
2015-08-29T18:17:43 < Laurenceb__> or both
2015-08-29T18:17:57 < zyp> or not
2015-08-29T18:17:59 < Laurenceb__> wifi is going to dropout and crash the drone
2015-08-29T18:18:34 < dongs> they just need to buy 20k pic32mzs
2015-08-29T18:18:37 < dongs> and run out of money
2015-08-29T18:18:40 < dongs> and close shop
2015-08-29T18:18:44 < Laurenceb__> guess they could roll a custom dvbt implementation on 2.4Ghz
2015-08-29T18:18:49 < Laurenceb__> but no chance with pic32
2015-08-29T18:18:51 < dongs> fuck off
2015-08-29T18:18:54 < Laurenceb__> lulz
2015-08-29T18:18:56 < dongs> off a 450mAh battery?
2015-08-29T18:19:00 < Laurenceb__> heh
2015-08-29T18:19:04 < dongs> that'll run for about 5 seconds
2015-08-29T18:19:15 < Laurenceb__> GoPro prob has enough horsepower
2015-08-29T18:19:23 < Laurenceb__> and it runs for hours
2015-08-29T18:19:35 < Laurenceb__> they need ambarella
2015-08-29T18:19:50 < dongs> ambarella runs lnix
2015-08-29T18:19:53 < Laurenceb__> heh
2015-08-29T18:19:59 < dongs> like actual lunix
2015-08-29T18:20:04 < Laurenceb__> that explains why its glitchy as fuck
2015-08-29T18:20:09 < dongs> some uboot trash or whaever
2015-08-29T18:20:15 < Laurenceb__> so they just need a few extra tasks on there
2015-08-29T18:20:18 < Laurenceb__> for control and shit
2015-08-29T18:20:35 < zyp> gopro wouldn't last an hour on 450mAh
2015-08-29T18:20:38 < Laurenceb__> GoPro can already do wifi streaming and control and shit
2015-08-29T18:20:40 < Laurenceb__> so
2015-08-29T18:20:51 < Laurenceb__>  >5minutes is better than what they have got
2015-08-29T18:20:54 < zyp> mine does around two om 1180mAh
2015-08-29T18:21:07 < Laurenceb__> if GoPro decide to build something similar zano are fucked
2015-08-29T18:21:14 < Laurenceb__> but then they are already fuckerd
2015-08-29T18:21:24 < dongs> they're fucked regardless

2015-08-29T20:02:21 < kakimir> anyone using 2mm jumpers?
2015-08-29T20:03:02 < kakimir> I wonder if there is wire connectors for those
2015-08-29T20:03:22 < kakimir> no

2015-08-29T20:05:05 < kakimir> size
2015-08-29T20:05:23 < kakimir> 2,54s look ridiculously huge for jumpers
2015-08-29T20:07:45 < kakimir> I think 2mm would be manageable

2015-08-30T00:59:06 < upgrdman> also, the way people use stats like that is stupid. some people count legit self-defence as a gun death. even if it's a cop defending himself.

2015-08-30T01:29:49 < karlp> sure, take off 10, hell, 20 percent.
2015-08-30T01:29:59 < karlp> you've still got wayyyyyyyy too many cop killings.
2015-08-30T01:30:12 < upgrdman> we've got way too many trouble makers ;)

2015-08-30T01:30:58 < karlp> "legit self defence" for cops is pretty fucking slim
2015-08-30T01:30:58 < upgrdman> im not saying theyre wrong

2015-08-30T01:31:53 < kakimir> why

2015-08-30T01:55:49 < upgrdman> karlp, i almost forgot. suicides are the NUMBER ONE type of gun death in the usa. they account for almost 60% of the gun deaths.
2015-08-30T01:55:59 < upgrdman> this is what i mean.
2015-08-30T01:58:43 < kakimir> but isn't it?
2015-08-30T01:59:13 < kakimir> 20% is accidents I bet
2015-08-30T02:00:50 < upgrdman> ?
2015-08-30T02:01:13 < upgrdman> suicide and "accidental discharge" are different categories
2015-08-30T02:01:23 < kakimir> play around with your rifle and while cleaning take a look in barrel if it's loaded

2015-08-30T02:03:06 < upgrdman> i don't know, but i also wonder what the break down of homicides is
2015-08-30T02:03:27 < upgrdman> because if a large portion of those homicides is bullshit like gang-on-gang violence, then who cares.
2015-08-30T02:04:20 < kakimir> natural selection doesn't take skips
2015-08-30T02:12:18 < kakimir> are you implying that suicides and gang-on-gang crap are not gun deaths?
2015-08-30T02:12:24 < upgrdman> no
2015-08-30T02:12:41 < upgrdman> im implying that we shouldn't care as much about those types of gun deaths
2015-08-30T02:13:10 < upgrdman> what matters is how many truely innocent people die
2015-08-30T02:13:31 < kakimir> no-one is innocent
2015-08-30T02:13:32 < upgrdman> and im not saying the usa isn't still at the top. probably with a big margin too.
2015-08-30T02:13:59 < upgrdman> but people should at least be looking at the right numbers.
2015-08-30T02:14:13 < zyp> https://www.youtube.com/watch?v=-g_NgNbM828 <- I think this guy have some good points
2015-08-30T02:19:06 < kakimir> I have like this believe that lose of innocence is the moment when you start your race with grim reaper and every wrong move you take is one less
2015-08-30T02:19:12 < upgrdman> lol yes, he's funny
2015-08-30T02:39:07 < kakimir> smart and funny

2015-08-30T04:44:14 < dongs> DFU as in ROM bootloader?
2015-08-30T04:44:19 < dongs> nothing blinks when its in taht mode
2015-08-30T04:44:25 < Reasoning> Oh.
2015-08-30T04:44:43 < dongs> and I duno if they have the USB-FS part that answers DFU hooked up or not
2015-08-30T04:44:56 < Reasoning> I definitely programmed this thing years ago over USB.
2015-08-30T04:45:07 < dongs> you mean via stlink?
2015-08-30T04:46:16 < Reasoning> Yeah, ST-Link.
2015-08-30T04:46:27 < dongs> well, then that has nothing to do with DFU
2015-08-30T04:46:41 < Reasoning> Ah, that would explain it.
2015-08-30T04:46:50 < dongs> download/use "STM32 ST-LINK Utility"
2015-08-30T04:47:01 < dongs> to flash stuff ,or setup a debugger / IDE that suports it directly
2015-08-30T04:48:23 < Reasoning> Thanks, looks like all I need to do is remove the ST-Link jumpers.
2015-08-30T04:48:31 < Reasoning> I don't know why I was getting DFU and ST-Link confused.
2015-08-30T04:48:57 < dongs> pretty sure the default settings are NOT to remove them.
2015-08-30T04:50:14 < Reasoning> Just plugging the MiniUSB doesn't get detected, I think there's some jumper I have to change, no?
2015-08-30T04:50:37 < dongs> i'd say your stlink part is hosed then
2015-08-30T04:50:54 < dongs> windows?

2015-08-30T04:52:04 < dongs> sorry to hear that

2015-08-30T04:52:39 < Reasoning> oh, it's my hub.

2015-08-30T14:31:42 < dongs> this is the piece of shit that died in my esx box
2015-08-30T14:42:59 < Laurenceb__> can anyone recommend a right angle SMD tactile switch?
2015-08-30T14:43:10 < Laurenceb__> the panasonic ones all need a PCB cutout
2015-08-30T14:43:14 < Laurenceb__> which is annoying
2015-08-30T14:43:39 < qyx_> standard omron ones?
2015-08-30T14:43:46 < dongs> SMD and right angle doesnt work too well
2015-08-30T14:44:09 < qyx_> aha smd
2015-08-30T14:44:15 < Laurenceb__> ah that would explain why i cant find many
2015-08-30T14:44:20 < Laurenceb__> annoying
2015-08-30T14:44:29 < dongs> i use the generic chinaspecial right angle 5mm ones
2015-08-30T14:44:36 < Laurenceb__> yeah those are too big
2015-08-30T14:44:53 < Laurenceb__> maybe microswitches, but they have low G rating
2015-08-30T14:45:02 < Laurenceb__> I'm trying to detect if a pcb is spinnin

2015-08-30T14:46:21 < qyx_> wat
2015-08-30T14:46:30 < qyx_> how much is a low cost single axis gyro?
2015-08-30T14:47:09 < Laurenceb__> its like 100krpm
2015-08-30T14:47:13 < qyx_> if the rate is too high..
2015-08-30T14:47:22 < qyx_> maybe an accel?
2015-08-30T14:47:32 < Laurenceb__> too high for any accel
2015-08-30T14:47:39 < dongs> you have a pcb spinning at 100krpm
2015-08-30T14:47:45 < dongs> and you want a smt switch to hit something with?
2015-08-30T14:47:50 < dongs> how long do you want it to stay on pcb?

2015-08-30T14:48:37 < Laurenceb__> no the accel forces the switch closed
2015-08-30T14:48:41 < Laurenceb__> to detect spinning
2015-08-30T14:49:05 < Laurenceb__> a panasonic RA tactile would work, but requires internal PCB cutout

2015-08-30T14:49:52 < dongs> i see it requires holes
2015-08-30T14:49:54 < dongs> but not cutout?
2015-08-30T14:50:06 < dongs> and there's a version withnout boss, too
2015-08-30T14:50:07 < Laurenceb__> hmm nice find
2015-08-30T14:50:17 < Laurenceb__> yeah that might work, or at least that series

2015-08-30T14:51:02 < dongs> are you getitng paid for all this pro/ee stuff
2015-08-30T14:51:05 < dongs> or is it your school wank
2015-08-30T14:51:34 < Laurenceb__> school lulwut
2015-08-30T14:51:39 < dongs> i dont even see a pcb with parts on it surviving 100k rpm
2015-08-30T14:51:40 < Laurenceb__> dood im pro
2015-08-30T14:52:06 < dongs> they'll get torn off the board
2015-08-30T14:52:35 < Laurenceb__> its only a few newtons on the parts
2015-08-30T14:52:42 < Laurenceb__> components are light
2015-08-30T14:57:19 < dongs> Thanks for clarification - but that's some bad news, isn't it? If I want to record some great HD footage I will have a pixelated slideshow on my smartphone, making it difficult to control the Zano... :(

2015-08-30T22:11:29 < mtbg> so no propane/air gun?
2015-08-30T22:11:30 < kakimir> ok
2015-08-30T22:11:44 < kakimir> so it is first spun
2015-08-30T22:11:54 < kakimir> then it launches itself
2015-08-30T22:14:40 < Laurenceb__> yeah
2015-08-30T22:14:49 < Laurenceb__> the nuts are glued onto the buttons
2015-08-30T22:14:59 < chris_99> Just wondering has anyone got any recommendations for an Ethernet PHY for an STM32 it looks like DP83848 seems to be used in a number of examples i've seen
2015-08-30T22:23:20 < Laurenceb__> mtbg: you are welcome to try propane/air :D
2015-08-30T22:25:19 < Roklobsta> chris_99: gonna use LWIP?
2015-08-30T22:26:25 < zyp> chris_99, I used ksz8081rnaca

2015-08-30T22:27:41 < chris_99> yeah i've heard of the microchip one too, not used any though yet
2015-08-30T22:28:09 < Roklobsta> find something that has stable drivers already
2015-08-30T22:28:13 < kakimir> Laurenceb__: and sideguards for nut?
2015-08-30T22:28:29 < zyp> Roklobsta, a phy doesn't really need drivers
2015-08-30T22:28:35 < Roklobsta> LOL
2015-08-30T22:28:37 < Laurenceb__> no it'll just be superglued on
2015-08-30T22:28:59 < Laurenceb__> <Roklobsta> its not really that high level
2015-08-30T22:29:38 < Roklobsta> well.  i missed the PHY bit.  got too excited with my LMGTFY.
2015-08-30T22:29:42 < kakimir> it's spun softly?
2015-08-30T22:29:48 < zyp> Roklobsta, most of what I've seen defaults to autonegotiation, so you can really just hook it up and push data through it
2015-08-30T22:29:53 < Roklobsta> yep
2015-08-30T22:30:29 < Roklobsta> chris_99: do you mean PHY or you want everything in one?
2015-08-30T22:30:42 < zyp> https://github.com/karlp/zypsnips/blob/master/ethernet-phys-jacks.txt <- this have been discussed here before too
2015-08-30T22:31:14 < zyp> ksz8081 is nice because it requires few external parts, and can do fun stuff like reflectometry for cable test

2015-08-30T22:32:02 < chris_99> Roklobsta, well i was looking at this module http://www.wvshare.com/product/DP83848-Ethernet-Board.htm PHY is the right name for that chip, isn't it?
2015-08-30T22:32:10 < zyp> yes
2015-08-30T22:33:17 < Roklobsta> yep.  are you sure you don't want the actual Eth chip AND a PHY?  What Eth chip are you using?
2015-08-30T22:33:29 < Roklobsta> is it built into the STM32?
2015-08-30T22:33:32 < zyp> Roklobsta, yes it is

2015-08-30T22:34:48 < zyp> and it'd be pretty silly to add an external 10 Mb/s MAC on SPI, when there's an internal 100 Mb/s MAC in the chip itself
2015-08-30T22:36:10 < Yoduza> sorry, is it normal price $15 for 10 x Cortex-M0 48MHz, 32KB ram 256KB Flash ?
2015-08-30T22:37:40 < zyp> $1.5 each? not super cheap, but not horribly expensive either

2015-08-30T22:44:28 < Lux> like any connectivity line stm32 has a mac build in
2015-08-30T22:45:27 < zyp> yeah, that's why it's called connectivity line

2015-08-30T22:49:04 < Lux> we are on a stm32 channel ?
2015-08-30T22:50:16 < zyp> Roklobsta, you're being silly, he explicitly asked for a PHY to use with STM32
2015-08-30T22:50:56 < zyp> it's okay that you didn't know STM32 came with built-in MACs, but you don't need to get hostile over it
2015-08-30T22:55:26 < Roklobsta> zyp: if you want to be pedantic the STM32L152 on the Disco, board in front of me doesn't have a MAC.

2015-08-30T23:18:18 < qyx_> both generations, also 8051, no problems & relatively cheap
2015-08-30T23:18:22 < karlp> yeah, you had the earlier part number in the file alreday :)
2015-08-30T23:19:12 < karlp> any comments on the 8051? you're down for 8031 and 8081, zyp with the 8081, emeb with the lan8720a with caution notes, and dongs with dp83848 :)

2015-08-30T23:36:46 < qyx_> aha, some have "active discharge" (about 1kohm) if you disable EN

2015-08-30T23:37:07 < Laurenceb__> yeah wtf
2015-08-30T23:37:14 < qyx_> so my approach wont work anyway

2015-08-30T23:39:16 < qyx_> i aws about to paste t
2015-08-30T23:39:42 < Laurenceb__> although...
2015-08-30T23:39:49 < Laurenceb__> the input decoupling cap might power it
2015-08-30T23:41:15 < Laurenceb__> ah no, EN threshold is 0.4v
2015-08-30T23:41:28 < Laurenceb__> so it should just disable the discharge circuit
2015-08-30T23:42:07 < qyx_> so it should work with EN tied to Vin?
2015-08-30T23:42:54 < kakimir> remember vregs usually dont like that out is higher than in
2015-08-30T23:43:36 < kakimir> unless otherwise mentioned
2015-08-30T23:46:32 < Laurenceb__> hmm
2015-08-30T23:46:40 < Laurenceb__> I've never had problems with it
2015-08-30T23:47:46 < Laurenceb__> on some the input will be back powered
2015-08-30T23:47:55 < Laurenceb__> but if i connect the EN pin that shouldnt matter

2015-08-30T23:58:14 < johntramp> it usually works fine but I have a bug which keeps bricking controllers, and the only way to revive is to program while pressing reset
2015-08-30T23:59:00 < qyx_> many things, entering power saving modes for example
2015-08-30T23:59:26 < kakimir> does your code touch clocks or modes?

2015-08-31T01:02:27 < kakimir> why spi is that slow?
2015-08-31T01:02:37 < kakimir> 80 would be better
2015-08-31T01:04:12 < jadew> R2COM, try PLL M: 4

2015-08-31T01:04:20 < jadew> P: 0
2015-08-31T01:04:37 < jadew> yes
2015-08-31T01:04:57 < jadew> well, it will give you exactly 20 MHz
2015-08-31T01:05:54 < jadew> and the APB would run at 80 MHz which is still pretty high
2015-08-31T01:06:29 < jadew> let me see if you can do better
2015-08-31T01:07:55 < jadew> it means 1
2015-08-31T01:07:58 < jadew> no?
2015-08-31T01:08:28 < jadew> right
2015-08-31T01:08:30 < jadew> 0 is 2
2015-08-31T01:08:42 < jadew> it's (1 + p) * 2
2015-08-31T01:09:02 < jadew> yeah
2015-08-31T01:10:30 < jadew> with a 20,875,000 clock you can have a 167 MHz sys clock
2015-08-31T01:11:16 < jadew> I mean SPI clock
2015-08-31T01:14:14 < Yoduza> so, 2 MCU's with 2 SPI each = 40 Mbit ?
2015-08-31T01:15:40 < Yoduza> ok. But m4 have SPI1,SPI2
2015-08-31T01:17:08 < jadew> R2COM, the only SPI clock frequency you can get with a 168 MHz sys clock is 10.5 MHz
2015-08-31T01:17:28 < jadew> you'll have to comrpomise on that
2015-08-31T01:18:20 < jadew> probably the best option
2015-08-31T01:18:31 < Yoduza> So, 10Mbit on m4 via SPI or 20 ?
2015-08-31T01:19:32 < Yoduza> i dont want forget about it

2015-08-31T01:23:00 < upgrdman> god damn it. found an ide that i love. it just had to be xcode, though.
2015-08-31T01:23:14 < upgrdman> there goes my dreams of cross-platform ide
2015-08-31T01:23:25  * Yoduza think what R2COM like I2C more then SPI
2015-08-31T01:23:41 < upgrdman> i2c @ 20MHz sounds like fun
2015-08-31T01:24:03 < upgrdman> guess you'd use a 5 ohm pull-up or something ;)
2015-08-31T01:24:09 < upgrdman> R2COM, xcode

2015-08-31T01:24:39 < upgrdman> im just coding in ansi c, but on a mac
2015-08-31T01:24:51 < Yoduza> lol
2015-08-31T01:24:53 < upgrdman> R2COM, im so gay for retina displays.
2015-08-31T01:25:24 < upgrdman> fwiw, even win10's handling of hi-dpi is still half baked
2015-08-31T01:25:55 < upgrdman> because osx is the only desktop os with first-class support for hi-dpi

2015-08-31T01:28:57 < upgrdman> R2COM, im dick get so hard when i think of the 5k ifag. so tempted, but want to wait for the next generation since i dont need a dekstop quite yet
2015-08-31T01:31:28 < upgrdman> it would also be nice if 4k displays did >60fps. 60 isnt bad, but man it'd be sweet to be a little better
2015-08-31T01:32:02  * upgrdman wants an 8k 120Hz monitor so bad
2015-08-31T01:32:30 < upgrdman> not sure about 120, but 8k has been done by sharp
2015-08-31T01:32:37 < upgrdman> err maybe not sharp, but some .jp company
2015-08-31T01:32:55 < upgrdman> not sure about connectivity tho
2015-08-31T01:33:00 < kakimir> what is the difference between 8k and 4k?
2015-08-31T01:33:04 < upgrdman> i dont think anything current can push enough dixels
2015-08-31T01:33:06 < kakimir> other than numbers
2015-08-31T01:33:14 < upgrdman> fucktons of pixels
2015-08-31T01:33:32 < upgrdman> 4k is something like 4000x2100 (but powers of 2)
2015-08-31T01:33:45 < kakimir> instead of fucktons of pixels there is triliofukton of them
2015-08-31T01:33:47 < upgrdman> 8k is maybe 8000x4200 or something like that

2015-08-31T02:25:52 < upgrdman> anyone know of a carrying container that would be good for carrying around random PCBs and small tools? i'm thinking of something like a small briefcase with egg-crate style foam padding, so you can just toss a board in there and it will hug it to keep it in place. only concern is ESD, so foam would need to be dissipative.
2015-08-31T02:29:08 < dongs> https://www.youtube.com/embed/ppQQ8337KHk
2015-08-31T02:29:34 < Roklobsta> just get a silicone (tupperware style) container to suit with snap on lid and fill with appropriate foam.
2015-08-31T02:31:04 < Roklobsta> a bread knife with the large serrations should cut up the foam neatly
2015-08-31T02:31:21 < upgrdman> ya, but dissipative foam? where to buy
2015-08-31T02:31:26 < upgrdman> egg crate style
2015-08-31T02:31:31 < Roklobsta> that's one for google.
2015-08-31T02:31:39 < upgrdman> k
2015-08-31T02:32:14 < Roklobsta> but you should be able to find the snaplid containers with the appropriate dimentsions easily and cheaply.  it doesn't have to be a pelican case.
2015-08-31T02:32:22 < upgrdman> ya
2015-08-31T02:32:31 < upgrdman> i could get those at the grocery store, ikea, etc.
2015-08-31T02:32:55 < upgrdman> hmmm
2015-08-31T02:33:26 < Roklobsta> glue the foam onto the lid
2015-08-31T02:33:52 < upgrdman> ya thats easy. glue or double stick foam tape

2015-08-31T05:32:11 < dongs> talsit: there's the oval hole on the side
2015-08-31T05:32:16 < dongs> so you're gonna need at leats like 3mm or so
2015-08-31T05:32:26 < dongs> for drill clearance
2015-08-31T05:32:58 < talsit> oval??
2015-08-31T05:32:59 < dongs> but
2015-08-31T05:33:04 < dongs> bigger problem is
2015-08-31T05:33:08 < dongs> HDMI cables have that shroud around them
2015-08-31T05:33:21 < talsit> yeah, is there a "recommended" pitch?
2015-08-31T05:33:23 < dongs> that's a good 4-5mm on each side

2015-08-31T05:53:37 < dongs> Something related to the script, I saw a post somewhere(magazine) from the news when I fly back from China last night. It seems a company start to build a drone for light print. Actually, it related to script. Will it be able to add a script module for people to share the script over the air. For e.g. People share the script by sending it over a wifi package. It can be some script module exchange package. Is that possible to be made on the apps? It would be fun for Z
2015-08-31T05:53:52 < dongs> what hte fuck is he even talking about
2015-08-31T05:54:03 < englishman> is this zano quote
2015-08-31T05:54:17 < dongs> yes
2015-08-31T05:54:27 < englishman> i think he means, someone can write a swarming plan in a zanoOS scripting language
2015-08-31T05:54:38 < englishman> then when you go visit your zano buddies is sends script to other zanos in swarm
2015-08-31T05:54:56 < dongs> I'm pretty sure to have any hope of swarming anything
2015-08-31T05:55:00 < englishman> so when it makes a spinning swastika in the air, the others follow
2015-08-31T05:55:04 < dongs> you need centimeter-level postion hold capability

2015-08-31T07:38:29 < englishman> I am commanding the industry with authority from God to get rid of USB and switch to simple high speed serial ports in 2024. There will be 8 serial ports on every desktop. You buy USB PCI card if you need it. Then, we add TELNET and FTP.
2015-08-31T07:38:41 < englishman> God said 640x480 16 color was a covenant, so it will never have a browser. I set a limit of 100,000 lines of code, forever. God said it must be perfect. We have 81,000 lines right now. 3rd party libraries are banned.

2015-08-31T13:50:31 < jadew> but I'm sure there are better paid options out there, but I wouldn't buy them since this is sufficient
2015-08-31T13:50:44 < jadew> firefox/chrome
2015-08-31T13:51:13 < Steffanx> Edge is best

2015-08-31T13:55:42 < jadew> I agree
2015-08-31T13:55:43 < ReadError> thunderbird eats up like 2gb of ram and outlook is well..outlook
2015-08-31T13:55:47 < jadew> thunderbird is garbage
2015-08-31T13:55:53 < jadew> lots of bugs
2015-08-31T13:56:03 < jadew> checked the source code = spagetti code
2015-08-31T13:56:34 < jadew> a lot of that crap is JS based

2015-08-31T13:56:42 < ReadError> google probably wants you to use webmail
2015-08-31T13:56:43 < jadew> (the stuff in thunderbird)
2015-08-31T13:56:50 < ReadError> but if you have a lot of different accounts, thats a pain
2015-08-31T13:56:54 < jadew> yeah
2015-08-31T13:57:07 < Steffanx> Dont do that.. Gmail is all you need

2015-08-31T13:57:23 < ReadError> well I have google apps stuf too
2015-08-31T13:57:50 < ReadError> which is gmail still sorta but the way you have to switch between accounts is a PITA
2015-08-31T13:58:09 < jadew> yeah
2015-08-31T13:58:27 < jadew> not to mention that you can remain logged in, in your work account by mistake
2015-08-31T13:58:33 < jadew> and google logs everything

2015-08-31T14:00:00 < jadew> I almost never close tabs
2015-08-31T14:00:14 < jadew> nor my PC
2015-08-31T14:00:15 < karlp> upgrdman: doxygen can process javadoc, and my ide's can all generate javadoc stuff automatically and presnet it well, so it's a good choice.
2015-08-31T14:00:23 < ReadError> hah yea, I normally just close everything when the box ran out of memory
2015-08-31T14:00:36 < ReadError> and just open a new window when I cant read tabs
2015-08-31T14:01:06 < jadew> ReadError, I really wonder why they didn't fix that by now
2015-08-31T14:01:10 < jadew> it's so stupid
2015-08-31T14:01:30 < jadew> and people have been complaining about it since the begining
2015-08-31T14:02:30 < ReadError> figured they could atleast make the tabs grow vertical
2015-08-31T14:02:35 < ReadError> like add another row
2015-08-31T14:02:41 < jadew> yeah
2015-08-31T14:02:43 < jadew> at least that
2015-08-31T14:02:54 < Steffanx> Me imagines what that looks like with 350 tabs
2015-08-31T14:03:16 < Steffanx> Imho tou have other issues when you have so many open
2015-08-31T14:03:41 < jadew> I remember reading something on the chromium page a while ago, how "Chromium" is what Chrome is, but without the spyware :P
2015-08-31T14:03:59 < Steffanx> Kind of
2015-08-31T14:04:07 < jadew> I think the original team was ticked with how much success Chrome has
2015-08-31T14:04:14 < ReadError> im not doing anything super secret that I care if they spy really
2015-08-31T14:04:19 < jadew> and I think the biggest problem there is that they don't contribute much
2015-08-31T14:04:22 < ReadError> I sorta like the syncing between pcs
2015-08-31T14:04:26 < jadew> if they were, they'd make those freaking tabs work
2015-08-31T14:04:59 < jadew> also, Chrome is absolutely poor when it comes to features, compared to FF
2015-08-31T14:05:56 < Steffanx> Sometimes i get the idea people use the tabs as bookmarks
2015-08-31T14:06:18 < jadew> I guess they do (me included)
2015-08-31T14:06:23 < jadew> like temporary bookmarks
2015-08-31T14:06:37 < Steffanx> Me too, have tabs open for weeks sometimes

2015-08-31T14:10:38 < ReadError> certain sites will force chrome to suck down 500MB
2015-08-31T14:11:03 < akaWolf> FF consume much less memory, than Chrome
2015-08-31T14:11:29 < ReadError> yea but I dont care much for FF
2015-08-31T14:11:41 < jadew> akaWolf, I wouldn't be so sure, some of those resources are shared
2015-08-31T14:12:07 < jadew> but they might get added up to each process
2015-08-31T14:12:49 < jadew> I like FF, but chrome seems to be much more responsive
2015-08-31T14:12:54 < akaWolf> jadew: my friend did some comparisons :)
2015-08-31T14:15:56 < Laurenceb__> lol thunderbird
2015-08-31T14:16:06 < Laurenceb__> where did my memory go
2015-08-31T14:16:12 < karlp> jadew: why the fuck would you want to give up more vertical realestate on stacked tabs? fucking widescreen already gives us less vertical
2015-08-31T14:16:37 < Laurenceb__> widescreen needs to die
2015-08-31T14:17:05 < jadew> karlp, because it's better than not being able to tell which tab is what
2015-08-31T14:17:13 < jadew> and I agree on the widescreen thing
2015-08-31T14:17:15 < Lux> how does that nvic interrupt stuff work ? higher numbers mean a higher priority right ?
2015-08-31T14:17:34  * jadew holds on tightly to 2 4:3 screens
2015-08-31T14:17:41 < karlp> or lower, like most other stuff on cortex?
2015-08-31T14:17:47 < karlp> always get confused by that.

2015-08-31T14:38:45 < zyp> why the fuck do you guys care how much ram web browsers consume? if they consume enough to pose a problem, you should buy more
2015-08-31T14:39:05 < dongs> who brought up teh browser topic
2015-08-31T14:39:20 < zyp> idk, I just got home and looked at chats
2015-08-31T14:39:20 < dongs> i mnust have been stoned/ loading dicknplace
2015-08-31T14:39:21 < dongs> missed it
2015-08-31T14:39:22 < dongs> o
2015-08-31T14:39:43 < zyp> just delivered boards to guys, they seemed happy
2015-08-31T14:39:47 < dongs> cool
2015-08-31T14:40:12 < dongs> lets hope next order is 100+ to get rid of the remaining trash i have here :)
2015-08-31T14:40:25 < dongs> chinagirl finally sent me the 2x13 connectors, its a huge cube wasting space in my storage
2015-08-31T14:40:44 < zyp> first they actually need to sell these 24
2015-08-31T14:40:51 < dongs> right :)
2015-08-31T14:42:58 < zyp> maybe I should design a zano clone so I have somewhere else to use them, doesn't they use silly huge connectors like that between the boards?
2015-08-31T14:44:00 < dongs> haha
2015-08-31T14:44:01 < dongs> right
2015-08-31T14:44:34 < dongs> Would it be possible to have the Zano perform a free fall with the camera pointing downwards, using the propellers only to adjust the angle? You need to be high enough (not you, the Zano ;) ) but this could work, no?
2015-08-31T14:44:47 < zyp> haha
2015-08-31T14:46:27 < dongs> Outdoor testing is obviously weather dependant so whenever the weather turns and is not suitable, I have headed inside and continued indoor testing.
2015-08-31T14:46:31 < dongs> I have added a compass calibration mode to Zano as well as done quite a bit of flight tuning.
2015-08-31T14:46:34 < dongs> I'll post more detailed information soon.

2015-08-31T15:09:32 < dongs> 15.1.15
2015-08-31T15:09:36 < dongs> or are tehy going to 15.2
2015-08-31T15:11:45 < karlp> I think the problem is more that certain web _sites_ can consume so much memory and cpu, not so much the browser itself.
2015-08-31T15:11:58 < dongs> yeah
2015-08-31T15:12:00 < dongs> for sure
2015-08-31T15:12:08 < karlp> one of the local news sites will spin my gf's laptop to 80% cpu and fan at full speed

2015-08-31T15:15:41 < zyp> unless I fire up a VM or run a long usb capture or shit like that

2015-08-31T15:20:26 < zyp> couple hundred milliamps, I guess
2015-08-31T15:20:34 < zyp> 500ma is probably good
2015-08-31T15:20:59 < zyp> will pwm shit across it, so average would be less

2015-08-31T17:48:14 < jpa-> swd/jtag/bootloader all do flash programming by running a bit of code on the processor anyway

2015-08-31T20:16:44 < Laurenceb__> I think its that most prototypers are businesses

2015-08-31T20:17:10 < Laurenceb__> also its hard to cut, so they need Nd:YAG

2015-08-31T23:15:16 < Reasoning> I've been debating if I should inventory all of my parts; I think that's overkill? I'm just doing usb thingy stuff and dev boards mostly.
2015-08-31T23:16:11 < zyp> sounds like more time than it's worth
2015-08-31T23:17:04 < Reasoning> For usb devices it was definitely worth it. Often I forget what the device appears as and I have to go find it only to plug it in and see it's the wrong interface.
2015-08-31T23:17:23 < zyp> passives I use enough of I've bought reels for, otherwise I just buy parts per project
2015-08-31T23:17:57 < zyp> the former is 100n caps and a couple of resistors
2015-08-31T23:18:07 < Reasoning> SMD reels?
2015-08-31T23:18:12 < zyp> of course
2015-08-31T23:18:24 < artag> this is pretty small http://esden.net/2012/07/13/black-magic/
2015-08-31T23:18:31 < Reasoning> I can't solder SMD, my hands aren't still enough.
2015-08-31T23:19:14 < Sync_> stabilize with your pinky
2015-08-31T23:19:14 < artag> use an iron where your fingers are near the tip. if it's a long way away, the trembling is magnified
2015-08-31T23:19:16 < ds2> steady hands don't matter that much
2015-08-31T23:19:28 < ds2> use hot air
2015-08-31T23:19:39 < zyp> I just put on parts and throw it in the oven
2015-08-31T23:20:02 < ds2> zyp: do you use an oven controller?
2015-08-31T23:20:21 < zyp> I bought some cheap oven with controller and all
2015-08-31T23:21:04 < ds2> how do you bring up your boards? I usually like to build it a section at a time and verify things as it gets built
2015-08-31T23:21:15 < zyp> http://bin.jvnv.net/f/lNfIS.JPG <- this shit
2015-08-31T23:22:02 < zyp> uh, that sounds like a waste of time
2015-08-31T23:22:20 < zyp> I just do it all at once and expect it to work
2015-08-31T23:22:35 < Steffanx> even for the first prototype?
2015-08-31T23:22:56 < zyp> then I reflow the board, inspect the board for solder bridges, power up the board, checking that no rails are shorted
2015-08-31T23:23:02 < Sync_> Steffanx: zyp is a pro, his circuits always™ work
2015-08-31T23:23:04 < zyp> then I check that the MCU replies on SWD
2015-08-31T23:23:19 < zyp> if I get that far then usually the rest of the board works too
2015-08-31T23:23:38 < zyp> Steffanx, first prototypes are usually a mess of wires and module-boards
2015-08-31T23:23:53 < Steffanx> ok, first pcb prototype you make.
2015-08-31T23:23:54 < zyp> http://bin.jvnv.net/f/BC358.JPG <- like this
2015-08-31T23:24:05 < Steffanx> or do you skip that phase
2015-08-31T23:24:14 < zyp> I don't assemble first prototype any differently from the rest I assemble
2015-08-31T23:24:23 < Sync_> he goes straight to full production
2015-08-31T23:24:37 < ds2> doesn't that cause problems when the analog side misbehaves?
2015-08-31T23:24:51 < zyp> in what sense?
2015-08-31T23:24:54 < Sync_> I usually test the powersupplies first and then solder all the rest
2015-08-31T23:25:09 < ds2> like unexplained noise
2015-08-31T23:25:22 < zyp> idk, I don't tend to do much analog stuff
2015-08-31T23:25:35 < ds2> not even signal conditioning for sensors, etc?
