2020-07-01T00:52:21 < PaulFertser> Apparently it's not strictly necessary to catch it with a net, and it can be reused after a "planned ocean landing" too.
2020-07-01T00:53:56 < Cracki> is it dense enough to sink? or do they just not like the salt water?
2020-07-01T00:55:02 < Cracki> > Saltwater is extremely corrosive, so keeping fairing halves dry makes reuse more feasible, Musk has said.

2020-07-01T01:57:03 < Laurenceb_> > The lexicon favored by intersectional theorists of this type is built around the same principles as Orwell’s Newspeak: it banishes ambiguity, nuance, and feeling and structures itself around sterile word pairs, like racist and antiracist, platform and deplatform, center and silence, that reduce all thinking to a series of binary choices. Ironically, Donald Trump does exactly the same thing, only with words like “AMAZING!” and “
2020-07-01T01:57:04 < Laurenceb_> SAD!” that are simultaneously more childish yet sound livelier.

2020-07-01T07:47:17 < Cracki> esp8266 is absolute garbage. it doesn't even support external interrupts while sleeping.
2020-07-01T07:47:47 < antto> aww, sh*tpressif8266
2020-07-01T07:48:04 < Cracki> you can send the modem to sleep but the cpu will still use 15 mA. if you want the cpu to sleep too ("light sleep"), it doesn't notice anything on the interrupts unless the wifi wakes it up (wifi is the only thing that can wake it from light sleep)
2020-07-01T07:48:09 < Cracki> yes, garbage docs
2020-07-01T07:48:13 < antto> with the stolen binary blobs and 9 levels of bootloaders
2020-07-01T07:48:39 < Cracki> it has a hardware timer and that thing seems to be able to do hardware pwm
2020-07-01T07:49:06 < Cracki> but the docs don't say how it counts, i.e. if the "ARR" is supposed to be f_cpu / prescaler / desired_freq, or same-1
2020-07-01T07:49:42 < Cracki> I'd assume same as rest of the world but this thing is so shit they might even fuck that up

2020-07-01T07:51:36 < antto> from building gcc to finding out that yer code goes in a smol function that cannot do very fancy things or it'll get in the way of teh dumb wifi process

2020-07-01T13:29:43 < dongs> Also: The xr819 chip/firmware drops tons and tons of frames with FCS errors and this makes performance horrible at best. Most people have lost interest in having anything to do with the xr819 because of people being idiots and demanding that issues that are incredibly hard to fix without documentation be fixed because they spent $8 on a board and somehow people that got exactly zero of their $8 are

2020-07-01T14:01:31 < zyp> yeah, the zero plus or whatever the newer one was called used something that actually works
2020-07-01T14:17:20 < jadew``> I made a thing: http://188.25.138.20/stuff/llna.jpg
2020-07-01T14:18:46 < jadew``> 50 MHz to 3 GHz limiting amplifier
2020-07-01T14:18:58 < jadew``> < 1 dB NF @ 1 GHz
2020-07-01T14:19:41 < jadew``> this variant has a guaranteed maximum output power less than 10 dBm
2020-07-01T14:20:54 < benishor> jadew``: very nice construction
2020-07-01T14:20:59 < benishor> where'd you get that case from?
2020-07-01T14:21:02 < jadew``> gain goes from 38 dB or so at 50 MHz down to ~16 - 17 dB @ 3 GHz
2020-07-01T14:21:10 < jadew``> benishor, I designed it and had it custom made
2020-07-01T14:21:20 < jadew``> it was expensive
2020-07-01T14:21:23 < benishor> jadew``: where exactly? sounds like an expensive job
2020-07-01T14:22:06 < jadew``> it is, yeah, found a CNC shop online, you'll find it if you search for prelucrare cnc
2020-07-01T14:24:27 < jadew``> I hope I'll be able to get the datasheet ready today
2020-07-01T14:24:31 < jadew``> I have so much other job to do...

2020-07-01T14:25:35 < jadew``> stainless steel with BeCu center conductor
2020-07-01T14:25:58 < benishor> how much did the casing cost?
2020-07-01T14:26:07 < benishor> what's the final price for one case?
2020-07-01T14:26:17 < jadew``> upwards of 70 EUR
2020-07-01T14:26:24 < benishor> holy fucking macaroni
2020-07-01T14:26:26 < jadew``> not sure exactly, went through a couple of variants
2020-07-01T14:26:40 < benishor> do you plan to sell those modules?
2020-07-01T14:26:44 < jadew``> yeah
2020-07-01T14:26:53 < benishor> that will surely add up fast to the final price
2020-07-01T14:27:08 < jadew``> yeah, it will definitely put a dent in my margin
2020-07-01T14:27:31 < jadew``> I don't even know if I'll be able to sell them lol
2020-07-01T14:27:55 < jadew``> at a profit that is
2020-07-01T14:28:03 < benishor> at least you made them for youself, so that's good

2020-07-01T14:35:36 < benishor> since the only thing that differs is the maximum allowed power
2020-07-01T14:36:02 < benishor> going from 3rd to 2nd opened a lot of bands I didn't have access to and was interested in
2020-07-01T14:36:14 < benishor> I'm more of a CW HF guy
2020-07-01T14:36:20 < jadew``> I see
2020-07-01T14:36:44 < jadew``> HF is full of noise where I live
2020-07-01T14:36:57 < jadew``> and I can't spread a decent antenna either
2020-07-01T14:38:26 < benishor> HF noise level is higher in any city anyways, but it still makes for some nice communication paths
2020-07-01T14:39:05 < benishor> I used a QRPLabs U3S on WSPR and got pretty much all continents with 200mW
2020-07-01T14:39:18 < benishor> it's amazing what technology can do
2020-07-01T14:39:35 < benishor> of course, most of the merit belongs to the software which allows negative SNR but still
2020-07-01T14:40:24 < benishor> to have reached antartica, new zealand and other spots in the world with two BF170 is quite something

2020-07-01T14:41:14 < onio> Hi all, I am trying to trap a hardfault exception on a STM32H750 processor developing with Keil ARM compiler v6.14, I found the following example code https://pastebin.ubuntu.com/p/6rVWqyR4Dj/ but when I build I get the following warning 
2020-07-01T14:41:27 < onio> "Warning: L6306W: '~PRES8 (The user did not require code to preserve 8-byte data objects)' section hardfault.o(.text) should not use the address of 'REQ8 (Code was permitted to depend on the 8-byte aligment of 8-byte data items)' function HardFault_Handler_c."
2020-07-01T14:41:29 < dongs> thats obviosuly gcc code
2020-07-01T14:43:40 < dongs> https://community.arm.com/developer/tools-software/tools/f/keil-forum/26775/overwrite-exception-handler
2020-07-01T14:43:45 < dongs> apparently you need that preserve8 shit in the asm
2020-07-01T14:43:47 < onio> dongs. I must confess I am not very familiar with assembly but I think since v5.xx keil arm assembly __asm() macro seems to no longer work 
2020-07-01T14:43:50 < dongs> assuming you can compile it
2020-07-01T14:44:18 < dongs> onio, it never did, there's zero valid reason to use asm inside .C files other than pre-existing cmsis macros
2020-07-01T14:44:57 < benishor> jadew``: yeah, the u3s is a transmitter/beacon kit which can produce many modes (qrss, fsk,cw, dfcw, wspr, opera, jt9, hellschreiber, etc)
2020-07-01T14:45:21 < dongs> anyway, you have fucking keil, why are you even fucking aroudn with hardfault handler
2020-07-01T14:45:33 < dongs> literally just set a breakpoint in HardFault and fucking look at registers right in the IDE
2020-07-01T14:45:37 < dongs> why do you want to waste time printing them
2020-07-01T14:46:00 < dongs> gcc turds print shit cuz gdb is garbage and debugging is impossible
2020-07-01T14:46:03 < benishor> that's a compile warning
2020-07-01T14:46:05 < dongs> but you have proper tools, so just use them
2020-07-01T14:46:10 < dongs> thats a linker warning but OK
2020-07-01T14:46:30 < benishor> by compile I meant compile time
2020-07-01T14:46:44 < benishor> compiler/linker/whatever
2020-07-01T14:46:53 < dongs> yeah the warning is in his shitty copypasted hardfault handler he copied from gcc
2020-07-01T14:49:45 < dongs> i dont see a reason for having such when using a proper debugger like keil or ozone
2020-07-01T14:49:56 < dongs> cuz you can just breakpoint in hardfault and done
2020-07-01T14:49:58 < onio> My application works fine when I am running with (segger J-Link) but when I flash the board standalone it does not work. So I am trying to see if it going into the hardfault handler
2020-07-01T14:50:21 < dongs> i bet you copied more lunix shit
2020-07-01T14:50:32 < dongs> and its breaking on 0xab when it tries to printf shit to debugger

2020-07-01T15:03:31 < benishor> the point was to use something which you can find anywhere
2020-07-01T15:03:53 < benishor> I'm not questioning that, it's just how things are
2020-07-01T15:04:04 < karlp> is this someanalog wider soundstage thing?
2020-07-01T15:04:28 < karlp> so the real thing is, "it's neat to do transcontinental comms on200mW" ? because thatI can getbehind :)

2020-07-01T15:47:57 < jadew``> they think there can be free speech under communism

2020-07-01T15:48:34 < jadew``> you can't get out of communism with a movement
2020-07-01T15:48:39 < jadew``> you need a revolution
2020-07-01T15:48:56 < benishor> we romanians should know
2020-07-01T15:49:00 < benishor> we had quite a "revolution"
2020-07-01T15:49:39 < benishor> I'm most interested to see where the whole white guilt thing is getting at
2020-07-01T15:49:54 < jadew``> that's a US problem
2020-07-01T15:49:55 < benishor> things went down south quite a lot
2020-07-01T15:50:08 < benishor> yeah, but sadly it ripples in europe as well
2020-07-01T15:50:23 < jadew``> not in Romania
2020-07-01T15:52:12 < benishor> jadew``: how about https://imgur.com/a/TY2m4MS ?
2020-07-01T15:52:36 < jadew``> lol, that's just a stock photo
2020-07-01T15:54:09 < jadew``> we don't have many non nationals in here
2020-07-01T15:54:12 < benishor> regardless :)
2020-07-01T15:54:33 < benishor> the projection works on gipsies
2020-07-01T15:54:34 < jadew``> the ones we do, are usually contributing members of society, because they came here to build something, not to live on welfare
2020-07-01T15:55:16 < jadew``> we don't have that many gypsies anymore

2020-07-01T15:56:59 < benishor> there's an impedance mismatch between what you state and what I see in brasov
2020-07-01T15:57:04 < jadew``> we didn't have slavery
2020-07-01T15:57:19 < benishor> we did, iobagi, serbi
2020-07-01T15:57:43 < benishor> but they were also whites so yeah, we stand better at it
2020-07-01T15:57:54 < jadew``> yeah, but they were the same race
2020-07-01T15:57:56 < jadew``> yeah
2020-07-01T15:57:58 < benishor> yey for us not being a colonialist power

2020-07-01T16:00:57 < jadew``> statues of personalities are representing certain ideas that those personalities stood for
2020-07-01T16:01:29 < Laurenceb> keeek incels are creating fake blm accounts
2020-07-01T16:01:29 < jadew``> they serve as a reminder of those ides, for the people living around those statues
2020-07-01T16:01:44 < Laurenceb> >>""schools should decolonise curriculum and libraries"
2020-07-01T16:02:00 < jadew``> now... I don't know what values those statues stand for and what they mean to the people in those cities
2020-07-01T16:02:02 < Laurenceb> >>lasses send me nudes in DMs
2020-07-01T16:02:07 < Laurenceb> lolling hard
2020-07-01T16:02:37 < jadew``> but whatever the values are, the only way to destroy them is to conquer that society
2020-07-01T16:03:11 < jadew``> stepping on the values of a society, is a very powerful message, and it's usually reserved for the victor, in a war
2020-07-01T16:03:23 < jadew``> or for invaders sometimes
2020-07-01T16:03:57 < benishor> nice way to put it
2020-07-01T16:04:31 < benishor> but the whole shenanigans does not change the fact that columbus et. amerigo contacted murrica first
2020-07-01T16:04:49 < aandrew> when I was in .ro my wife would point out gypsies a mile away
2020-07-01T16:05:10 < aandrew> the obvious ones I could see (coins in the hair, day-glo coloured flowy skirts, etc.) but most of them I had no clue
2020-07-01T16:05:19 < Laurenceb> my mum went to Romania in the 80s
2020-07-01T16:05:32 < Laurenceb> she got a beating from hookers who assumed she was competition
2020-07-01T16:05:40 < benishor> aandrew: they are pretty easy to spot. unique traits
2020-07-01T16:05:47 < jadew``> Laurenceb, she came back pregnant with you?
2020-07-01T16:05:48 < benishor> Laurenceb: lol wtf
2020-07-01T16:05:53 < Laurenceb> and some guy sprayed her with bleach
2020-07-01T16:06:17 < benishor> was she black?
2020-07-01T16:06:22 < Laurenceb> lol
2020-07-01T16:06:31 < benishor> just trying to put the pieces together 
2020-07-01T16:06:32 < Laurenceb> no just dressed like a slut i guess
2020-07-01T16:06:32 < benishor> :D
2020-07-01T16:06:54 < benishor> sluts and pimps are quite teritorial indeed

2020-07-01T16:07:07 < Laurenceb> >ur mum
2020-07-01T16:07:32 < aandrew> I mean sorry your mom got beat up but that is kind of funny as an anecdote
2020-07-01T16:07:38 < Laurenceb> ikr
2020-07-01T16:08:31 < Laurenceb> she snuck into russia too, funtimes
2020-07-01T16:08:52 < aandrew> I can't imagine sneaking into a communist country 
2020-07-01T16:09:07 < aandrew> although my wife said she was regularly smuggling shit back from turkey
2020-07-01T16:09:19 < Laurenceb> aiui it was for epin banter
2020-07-01T16:10:08 < aandrew> and she was a border guard ("papers please") I think on the serbian border? on the southwest side of the country, near Timis I think
2020-07-01T16:10:45 < Laurenceb> wew I think thats where my mum wnet through back in the day
2020-07-01T16:10:52 < benishor> aandrew: then she definitely made a lot of cash
2020-07-01T16:10:55 < aandrew> it sounds like you come from a long line of trolls
2020-07-01T16:11:06 < jadew``> lol

2020-07-01T21:37:47 < superbia> WB
2020-07-01T21:38:44 < s34n> How do I minimize the noise that an analog gpio pin absorbs from the air?
2020-07-01T21:40:12 < aandrew> s34n: you connect it to a low impedance source
2020-07-01T21:40:26 < Steffanx> How many people did you kill since last time superbia?
2020-07-01T21:40:37 < aandrew> easiest, fastest, cheapest way to do this: any old opamp, connect - to output, + to your high impedance signal
2020-07-01T21:40:39 < superbia> probably not more than you Steffanx https://www.reddit.com/r/CatastrophicFailure/comments/hj9xvh/river_cargo_ship_crashes_against_bridge_and_loses/
2020-07-01T21:41:33 < s34n> aandrew: I'm just trying to read a pot
2020-07-01T21:41:33 < Steffanx> nothing happened there
2020-07-01T21:41:52 < Steffanx> and it were the germans... again superbia.
2020-07-01T21:41:54 < englishman> cool
2020-07-01T21:42:04 < aandrew> s34n: opamp
2020-07-01T21:42:25 < aandrew> but mind you, the pot is probably a 100k or 470k pot and the opamp is just going ot buffer all that noise anywya
2020-07-01T21:42:30 < englishman> you chop the signal and use a lock in amplifier
2020-07-01T21:42:50 < aandrew> englishman: that's way overkill to read a pot
2020-07-01T21:42:54 < englishman> so?
2020-07-01T21:43:02 < superbia> Steffanx: I am cuckholded by this corona chan fucking virus
2020-07-01T21:43:04 < englishman> he wanted to minimize noise
2020-07-01T21:43:17 < aandrew> fair enough
2020-07-01T21:43:18 < englishman> that will do it
2020-07-01T21:43:39 < Steffanx> lol
2020-07-01T21:43:51 < englishman> superbia: thanks for the recommendations I ended up getting a sinn
2020-07-01T21:43:58 < superbia> englishman: which one
2020-07-01T21:44:03 < englishman> 103
2020-07-01T21:44:04 < Cracki> s34n, present lots of facts. all the component values involved
2020-07-01T21:44:10 < Cracki> sampling frequency too etc
2020-07-01T21:44:18 < superbia> englishman: a true classic
2020-07-01T21:44:20 < superbia> congratulations
2020-07-01T21:44:25 < superbia> you owe me a wrist shot
2020-07-01T21:44:28 < englishman> ty yes it's nice
2020-07-01T21:44:35 < s34n> it's a 10K pot
2020-07-01T21:44:40 < englishman> though I use the dial more than the chrony
2020-07-01T21:44:46 < Cracki> s34n, there's an appnote from st on ADC and noise/good practices
2020-07-01T21:44:48 < ds2> keep it cold like 0K cold
2020-07-01T21:45:04 < Cracki> also what noise levels do you see
2020-07-01T21:46:01 < Cracki> another source of noise is the controller itself
2020-07-01T21:46:08 < superbia> englishman: quick picture?
2020-07-01T21:46:20 < s34n> the adc is reading 2000 with nothing across the pot
2020-07-01T21:46:31 < Cracki> "nothing"?
2020-07-01T21:46:44 < Cracki> and how's the noise?
2020-07-01T21:46:52 < Cracki> what stm32 is it
2020-07-01T21:46:54 < s34n> (if I disconnect the pot)
2020-07-01T21:46:56 < Cracki> some want calibration
2020-07-01T21:46:59 < Cracki> so it's floating
2020-07-01T21:47:06 < Cracki> floating pin can read anything
2020-07-01T21:47:12 < s34n> stm32f103
2020-07-01T21:47:18 < Cracki> that one has no adc calib

2020-07-01T21:51:05 < englishman> thanks it's pretty nice
2020-07-01T21:51:14 < superbia> the crystal is plexi ? or sapphire ?
2020-07-01T21:51:25 < englishman> the tesla got another update today Steffy
2020-07-01T21:51:44 < englishman> plexi, I didn't like How the sapphire one looked and it was much taller
2020-07-01T21:52:21 < superbia> yup, just don't drink too much when you are out and you will be golden
2020-07-01T21:52:30 < englishman> it now proceeds at green lights without intervention
2020-07-01T21:52:37 < Steffanx> You should never drunk too much, superbia.
2020-07-01T21:52:38 < Steffanx> come ooon
2020-07-01T21:52:45 < englishman> yes alcohol is bad for you
2020-07-01T21:52:48 < superbia> or get the U1 for dem drinking sessions
2020-07-01T21:53:13 < superbia> I've seen U1 being thrown, and glass tables broken with it
2020-07-01T21:53:24 < Steffanx> You dont get a "classy"  watch to go non-classy drunk.
2020-07-01T21:53:26 < superbia> don't ask me how shit faced we've been
2020-07-01T21:54:04 < superbia> and there's a a few U1 dings on door frames, my friend made
2020-07-01T21:55:59 < Steffanx> So whats up mr superbia? Still in swisserland?
2020-07-01T21:56:18 < superbia> Swissin the swiss life
2020-07-01T21:56:37 < superbia> got offers to go to norway
2020-07-01T21:57:46 < Steffanx> nah, does norway even make fancy watches?
2020-07-01T21:58:42 < superbia> the woman in switzerland are not great..
2020-07-01T21:58:55 < Steffanx> Just import one
2020-07-01T21:58:55 < superbia> I think I'd preffer nordic woman more
2020-07-01T21:59:01 < superbia> import from ?

2020-07-01T22:09:18 < superbia> englishman: one final point, if you travel alot and if you decide to go more swiss horology (higher $), just check if it's ok to walk in a particular country with expencive watch on your wrist, because customs
2020-07-01T22:10:29 < englishman> good point
2020-07-01T22:10:41 < englishman> not leaving the country this year but i'll keep it in mind
2020-07-01T22:11:04 < superbia> also, it's better to go incognito with real value brands such as Sinn
2020-07-01T22:11:32 < superbia> you can pretty much move it without anyone even noticing (except people who know watches, they will complement you)
2020-07-01T22:11:56 < Steffanx> i think englishman has a trustworthy face, customs wont stop him
2020-07-01T22:12:07 < superbia> so just to be sure, have a photo of receipt and/or warranty, and/or box papers on your phone
2020-07-01T22:12:15 < englishman> https://www.sinn.de/en/Modell/356_Sa_PILOT_II.htm
2020-07-01T22:12:15 < superbia> he is mi6, nobody fucks with him
2020-07-01T22:12:18 < englishman> i liked this one as well
2020-07-01T22:12:33 < superbia> you did well with 103. it's the classic
2020-07-01T22:12:33 < englishman> but it is surprising how much i use the dial vs. the chrony
2020-07-01T22:13:23 < s34n> Cracki: with an stm32f103, I have pb5 <-> pot.1 <=> pot.3 <-> pb0, where pb5 is pushpull output and pb0 is analog. If I oneshot an adc with pb0, I get a reading of ~2000 no matter how I set the pot
2020-07-01T22:13:30 < englishman> https://i.imgur.com/oZoN9qt.jpg
2020-07-01T22:13:36 < superbia> for instance, if you try to walk into russia with a golden rolex, or patek, you will get relieved of your watch instantly

2020-07-01T22:19:29 < superbia> englishman: I can also give you suggestions for cheap watches, just let me know the budget
2020-07-01T22:19:58 < englishman> https://www.sinn.de/en/Instrument_Watches/EZM_3F.htm
2020-07-01T22:20:04 < englishman> is there something like this, but $300
2020-07-01T22:20:14 < englishman> ie. something i can drag across concrete
2020-07-01T22:20:58 < superbia> I'd say you up the budget and get some quality shit
2020-07-01T22:21:10 < englishman> hence assembling one could be cool, with the same movement then i can just buy a bunch of cases
2020-07-01T22:21:33 < superbia> casio oceanus S100 (Titanium) or T200 (SS)

2020-07-01T22:23:29 < Steffanx> is it smart?
2020-07-01T22:23:33 < superbia> the only reason I didn't buy one myself is because I already have a similar watch that does the same thing.
2020-07-01T22:23:56 < superbia> Steffanx: no. but it's accurate, thermally compensated, quartz, with radiowave calibration
2020-07-01T22:24:09 < superbia> and entire dial is solar panel, which means no battery changes...

2020-07-02T05:29:49 < Cracki> all I need is to count pulses (~1/sec), take ~millisecond time between pulses, and send that off over wifi, and sleep in between
2020-07-02T05:31:28 < Cracki> (my seemingly ancient) esp1488 is too dumb for it, either will only sleep the modem but not the core (meaning ~15-20 mA baseline), or will miss edges on the pin, which I could work around by making a flipflop that it resets when it's seen the level
2020-07-02T05:31:53 < Cracki> stm and using that AT command shit with an esp... I am shuddering
2020-07-02T05:36:34 < Cracki> someone started this but forgot nrf https://en.wikipedia.org/wiki/List_of_Wi-Fi_microcontrollers
2020-07-02T05:38:47 < Cracki> nvm, nrf seems to be unsuitable for 802.11
2020-07-02T05:40:02 < rajkosto> nrf is their own low latency protocol
2020-07-02T05:40:26 < Cracki> I'm disinclined to set up internet of shit using bluetooth
2020-07-02T05:41:03 < aandrew> nrf has no wifi connecivity
2020-07-02T05:42:03 < Cracki> I'm seeing TI cc31xx/32xx. how's that, anyone got any opinions? it's got a CM4 in it and seems to support 5 GHz
2020-07-02T05:42:20 < aandrew> cc31xx is ARM? 
2020-07-02T05:42:32 < Cracki> they claim so https://www.ti.com/wireless-connectivity/simplelink-solutions/wi-fi/overview/overview.html
2020-07-02T05:43:32 < aandrew> huh TIL
2020-07-02T05:43:35 < aandrew> I thought it was 8051 shit
2020-07-02T05:43:42 < aandrew> or is that 3300

2020-07-02T05:44:35 < aandrew> gotcha
2020-07-02T05:44:53 < Cracki> smells like you're supposed to use it as a modem, and do your own application processor
2020-07-02T05:45:28 < Cracki> I have some bluetooth modules from TI, also CCsomethingsomething
2020-07-02T05:45:32 < Cracki> impossible to tell apart
2020-07-02T05:45:56 < Cracki> 2541 I think
2020-07-02T05:50:37 < Cracki> CC31xx is CM3 and supposed to go with your own mcu/processor, CC32xx is CM4 and supposed to be both
2020-07-02T05:53:35 < Cracki> didn't find much TI CC31/32xx on aliex, only C3200 (2.4 GHz only) modules for "cheap"
2020-07-02T05:53:48 < dongs> CC1310 is the shit my dudes bought 10k of
2020-07-02T05:54:05 < dongs> ah M3
2020-07-02T05:54:14 < dongs> but the development environment is absolutely aids
2020-07-02T05:54:20 < dongs> you ahve to use crap composter with some autogenerated shite
2020-07-02T05:54:21 < dongs> and TI's lib
2020-07-02T05:54:26 < dongs> i tried to make a barebones keil project for it
2020-07-02T05:54:27 < dongs> and gave up
2020-07-02T05:54:30 < dongs> just too much aids
2020-07-02T05:54:51 < dongs> also you can't just download any of the libs etc it needs
2020-07-02T05:54:59 < dongs> you have to install crap composter and downlaod some packs or whatever
2020-07-02T05:55:13 < dongs> and its all millions of nested folders thats impossible to add to an IDE for building
2020-07-02T05:57:01 < Cracki> I had the misfortune of using composter once. 30 seconds to build, upload, and start debugging. insanity
2020-07-02T05:57:38 < Cracki> their cc31/32xx wifi thingies also talk about a "library"...
2020-07-02T05:58:03 < Cracki> at least with a cortex M in there people will shit on them more than for the awful support they can deliver for an 8051 core

2020-07-02T15:24:04 < Cracki> "data science" meaning excel warrioring at most
2020-07-02T15:24:16 < strata> because there isn't
2020-07-02T15:24:35 < Cracki> these fucksticks use pandas because they heard it's what the serious analysts use
2020-07-02T15:24:40 < strata> if you look at any of these "activists" on github who start these kinds of projects - they often have a lot of interest in machine learning, but aren't necessarily doing anything in the field.
2020-07-02T15:25:07 < strata> i think it's because they worship transhumanism - because that's what their idols (the global elite) worship.
2020-07-02T15:25:20 < Cracki> they love to say "sniff test". my sniff test of these people says they're a bag of shit playing dressup.
2020-07-02T15:26:57 < strata> anyway they're not commies
2020-07-02T15:27:03 < strata> they're just really gullible people, imo
2020-07-02T15:27:59 < strata> they latch on to an idea, and the platforms help it grow into a sort of hive mind built on mental disorder
2020-07-02T15:28:09 < Cracki> fun to observe, this has been simmering for over a year and in june it suddenly exploded
2020-07-02T15:28:40 < Cracki> they're really preparing this shit far in advance, then unleashing it at the right crisis
2020-07-02T15:29:02 < strata> nah. i think you're giving it too much credit. as forrest gump said - stupid is as stupid does.
2020-07-02T15:29:21 < Cracki> look at this graph https://github.com/collective-action/tech/graphs/contributors
2020-07-02T15:29:33 < strata> they're not intelligent enough to "unleash" something at the "right crisis"
2020-07-02T15:29:52 < strata> they see the rest of the mob moving a certain way, so they move too.
2020-07-02T15:29:56 < Cracki> number two does literally NOTHING else. and also is a sociology PHD! https://github.com/nataliyaned
2020-07-02T15:30:09 < Cracki> they're given marching orders, they can obey commands
2020-07-02T15:30:23 < strata> notice how it takes a wave of stupidity to get them to do something meaningful (to them at least) ?
2020-07-02T15:30:28 < Cracki> this shit is steered from higher up
2020-07-02T15:30:29 < strata> otherwise the repo just sits there...
2020-07-02T15:30:44 < strata> it's truly not. there's no top-level grand design running this shit.
2020-07-02T15:31:13 < Cracki> there is. every time those groups are infiltrated, enormous structures are unearthed.
2020-07-02T15:31:30 < Cracki> commies have been practicing this for over a century
2020-07-02T15:32:20 < strata> yeah and those structures often end up being comprised of the same power players... but that doesn't mean there's some grand conspiracy of individuals planning all of this stuff - it just means that those individuals you keep seeing pop up are the stronger voices among a giant mob of that mentally defective hive mind
2020-07-02T15:33:04 < Cracki> call it larping but it's not disorganized. they are passing "info material" around, they hold workshops on everything ("street medics", how to march through institutions, how to literally maim the enemy, ...)
2020-07-02T15:33:40 < strata> and yet it exists p much solely on the internet
2020-07-02T15:33:46 < strata> have you ever seen these people IRL?
2020-07-02T15:33:48 < Cracki> the connective tissue keeps to the shadows, leaving the newly indoctrinated to do public action
2020-07-02T15:34:28 < strata> they look like they haven't been outside in years. they are incapable of social interaction. they're irrelevant.
2020-07-02T15:34:28 < Cracki> every time they organize "counter protests", IRL
2020-07-02T15:34:56 < strata> they live in a different reality where their voices matter
2020-07-02T15:35:43 < Cracki> heh now I see why you call it a bot. it is a bot. https://github.com/collective-action/tech/commits/master
2020-07-02T15:36:04 < Cracki> all it does is change a timestamp. wat ze fuk
2020-07-02T15:36:37 < strata> yeah. to game the github stats to make the "movement" or whatever look big and strong.
2020-07-02T15:36:46 < strata> if they're doing shit like that on github, what other platforms do they do it on?
2020-07-02T15:37:02 < strata> see? the majority of these groups/individuals/movements/whatever you want to call them are shams.
2020-07-02T15:37:14 < Cracki> see that shit? that shit is not how you do data! separate strings instead of one comma separated one https://github.com/collective-action/tech/blob/master/actions/0000.json#L5
2020-07-02T15:38:12 < Cracki> what you call a sham is children playing. they'll grow out of it and then they'll be cogs in the machine that works to murder us all
2020-07-02T15:38:36 < Cracki> it's practice to praxis.
2020-07-02T15:39:33 < Cracki> fire drills. a big part of their MO. drill "doing something" into people's minds. make the motions automatic. program them to react to commands and situations.
2020-07-02T15:40:12 < strata> that's why folks in here are building greenhouse stuff now
2020-07-02T15:40:16 < Cracki> they condition their own, which in turn condition the masses to cringe and expect shrieking if they do something "wrong"
2020-07-02T15:40:27 < strata> probably for some elites, but still...
2020-07-02T15:40:36 < strata> let's do it for ourselves
2020-07-02T15:40:38 < Cracki> greenhouses have always been built
2020-07-02T15:40:42 < Cracki> ye do it
2020-07-02T15:41:05 < strata> my garden and hydro peppers are going cray cray this year
2020-07-02T15:41:13 < srk> plan some oil

2020-07-02T15:42:06 < strata> and i finished my cluster of doom

2020-07-02T15:46:29 < srk> lol what do you expect? :) heated discussion where people like you can vent?
2020-07-02T15:47:31 < srk> changing license is not really feasible as you need agreement of all the authors

2020-07-02T16:27:45 < braindamage> a shitty cluster
2020-07-02T16:28:39 < srk> yeah, probably way more powerful than your desktop if it uses pi4s :)
2020-07-02T16:28:57 < Cracki> beside its "moderate" but still appreciable crunch, it's a learning tool

2020-07-02T17:15:12 < karlp> so, undef behaviour quiz, is & instead of && here actually undefined? or just poor form? https://github.com/libopencm3/libopencm3/blob/master/lib/stm32/common/adc_common_v1.c#L591
2020-07-02T17:23:46 < dongs> uh
2020-07-02T17:23:50 < Ultrasauce> the defined value of a relational expression is 1 or 0
2020-07-02T17:24:03 < Ultrasauce> so it's "fine"
2020-07-02T17:24:15 < dongs> you should use && there
2020-07-02T17:24:43 < Ultrasauce> also what is a for loop
2020-07-02T17:25:10 < Streaker> AND is |
2020-07-02T17:25:21 < Streaker> if expr | expr is legal
2020-07-02T17:25:27 < Streaker> if expr && expr is illegal
2020-07-02T17:25:37 < Streaker> err
2020-07-02T17:25:40 < Streaker> you know what I mean
2020-07-02T17:25:46 < Ultrasauce> i definitely do not
2020-07-02T17:26:19 < Streaker> && is not AND
2020-07-02T17:27:36 < Cracki> the value of a comparison is zero or nonzero
2020-07-02T17:27:56 < Cracki> it being allowed to be nonzero, which may not be simply 1, is what gets you
2020-07-02T17:28:27 < Cracki> && is boolean and, & is bitwise and
2020-07-02T17:29:44 < Cracki> hm, some language lawyering seems to conclude that in C11, == and != are supposed to be 1 or 0... https://stackoverflow.com/questions/37291681/does-the-c-standard-explicitly-indicate-truth-value-as-0-or-1
2020-07-02T17:30:17 < Ultrasauce> that has always been the standard
2020-07-02T17:31:03 < karlp> it's definitely "wrong" it shoudl be &&
2020-07-02T17:31:16 < Ultrasauce> technically correct is the best kind of correct
2020-07-02T17:31:26 < karlp> but I believe it's also well defined, and there fore technically _ok_ even if not ideal
2020-07-02T17:31:32 < Ultrasauce> yes
2020-07-02T17:31:45 < Ultrasauce> you'd run into trouble if you say dropped a pointer into one of the operands for a null check
2020-07-02T17:31:46 < Streaker> https://www.techopedia.com/definition/25580/address-of-operator--c
2020-07-02T17:31:55 < karlp> yes, it's only ok because the tests are all bools
2020-07-02T17:32:35 < Ultrasauce> which is why i think it's also good practice to use !! to make 'bool' conversions very explicit
2020-07-02T17:36:11 < Cracki> I don't think there's any danger of the compiler thinking it's an address-of operator in that expression
2020-07-02T17:37:13 < Cracki> parsers haven't had to strain their little transition tables over this in decades

2020-07-02T18:23:22 < jpa-> karlp: do you have recommendations about ridicously high baudrate SWO capture devices for use with orbuculum?
2020-07-02T18:23:47 < jpa-> ideally i'd like something like FT2232H but which would go up to 32Mbaud or more
2020-07-02T18:23:48 < karlp> I just use stlink, it's been high enough for me.
2020-07-02T18:23:56 < karlp> so... no? :)
2020-07-02T18:24:00 < karlp> stlinkv3?
2020-07-02T18:24:46 < karlp> ft2232 can get you to what, 15M?
2020-07-02T18:25:10 < jpa-> 12Mbaud max
2020-07-02T18:25:26 < karlp> out of my league sorry
2020-07-02T18:25:52 < jpa-> and because my CPU is at 64MHz, i have to divide down to 4Mbaud to get them to match
2020-07-02T18:26:06 -!- oofus_ [~quassel@185.93.28.66] has quit [Read error: Connection reset by peer]
2020-07-02T18:26:21 < karlp> what?
2020-07-02T18:26:45 < karlp> why do they need to be multiples?
2020-07-02T18:29:49 < jpa-> hmm, i'm not sure if i've confused something
2020-07-02T18:30:24 < jpa-> it's hard to find out what baudrates FT2232H actually does support
2020-07-02T18:30:45 < karlp> yeah, serial above 1M is "magic workarounds and hacks land"
2020-07-02T18:31:20 < jpa-> but if it is 12, 12/2=6, 12/3=4, and i can get 64/2, 64/3.. out of my CPU, then first match is at 4Mbaud
2020-07-02T18:32:36 < karlp> I thought the swo clock taps were a bit more granular than that...
2020-07-02T18:32:43 < karlp> but I've nto looked in a whle
2020-07-02T18:32:53 < jpa-> no, it does not have fractional divider
2020-07-02T18:34:12 < karlp> I thought it had a second match thing, but that might just be the pc sampling bit actually.
2020-07-02T18:34:29 < fenugrec> jpa-, one of those fancy cypress FX3 ?
2020-07-02T18:35:23 < jpa-> karlp: yeah, the baudrate is just a simple divider register (TPI->ACPR)
2020-07-02T18:35:53 < jpa-> fenugrec: even USB2 speeds would suffice, but i think both FX2 and FX3 lack high-speed USART
2020-07-02T18:36:09 < jpa-> high-speed manchester decoder would be ok too, but that is even more rare
2020-07-02T18:38:13 < aandrew> I have to give orbuculum a try, it's been bookmarked and "oh that looks neat" for probably 6-9mos now
2020-07-02T18:38:15 < fenugrec> I assumed that was the kind of thing the FX gpio could be configured to do, but TBH I haven't played with those at all.
2020-07-02T18:38:42 < jpa-> should be pretty easy to on most FPGAs, but then i'd need to figure out a nice FPGA board with high-speed USB on it
2020-07-02T18:39:03 < aandrew> can FTDI's USB3 version of FT2232 do it? or did they get rid of all the modes in their new one
2020-07-02T18:39:16 < jpa-> ice40-hx8k breakout is stupid in that the FT2232H only has the same limited speed USART hooked up, instead of high-speed parallel fifo
2020-07-02T18:41:25 < jpa-> i now think FT2232H might support some other baudrates between 12Mbaud, 6Mbaud and 4Mbaud, but their datasheet does not seem to specify and i can't figure out https://github.com/torvalds/linux/blob/18d0eae30e6a4f8644d589243d7ac1d70d29203d/drivers/usb/serial/ftdi_sio.c#L1175
2020-07-02T18:41:52 < emeb> Glasgow? That has a high-speed cypress USB on it IIRC

2020-07-02T18:43:31 < PaulFertser> jpa-: I thought you can use any integer divisor from 60 MHz.
2020-07-02T18:43:34 < jpa-> emeb: hmm yeah, glasgow looks like it might do it on hardware side, not sure if the software is up to it
2020-07-02T18:43:43 < Cracki> https://www.ftdichip.com/Support/Documents/AppNotes/AN232B-05_BaudRates.pdf
2020-07-02T18:43:48 < PaulFertser> jpa-: so you get 12 MHz with /5 and 10 with /6 etc.
2020-07-02T18:44:06 < Cracki> >Divisor = n + 0, 0.125, 0.25, 0.375, 0.5, 0.625, 0.75, 0.875; where n is an integer between 2 and 16384 (214).
2020-07-02T18:44:37 < Cracki> odd, they said in the other document it's a 4 bit fraction, I see 3 bits here
2020-07-02T18:45:38 < jpa-> hmm, if that is correct then 8 MHz should work, but it doesn't for some reason
2020-07-02T18:45:40 < PaulFertser> Cracki: FT2232D != FT2232H
2020-07-02T18:46:14 < Cracki> did you guy stalk about the -D? I thought you talked about -H
2020-07-02T18:46:23 < jpa-> i'm talking about -H
2020-07-02T18:46:34 < jpa-> but that appnote just says FT2232 so i don't know anything anymore
2020-07-02T18:46:36 < PaulFertser> Cracki: but your link says just FT2232 and mentions 48 MHz base clock.
2020-07-02T18:46:43 < PaulFertser> Cracki: while I know FT2232H uses 60 MHz.
2020-07-02T18:46:46 < Cracki> this links to that https://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT2232H.pdf
2020-07-02T18:46:59 < Cracki> one instance of "fract"
2020-07-02T18:47:58 < jpa-> eh.. and actually now that i'm not being stupid, the chip i have is FT232HL

2020-07-02T18:49:50 < emeb> so many variations
2020-07-02T18:49:53 < jpa-> FTDI AN120 seems to have for FT2232H also
2020-07-02T18:52:14 < jpa-> still seems like 8Mbayd should work though, and also 10.66667Mbaud
2020-07-02T18:55:35 < jpa-> i can get 32Mbaud to logic analyzer just fine, but then i lack the realtime stuff of orbuculum; perhaps i should write some funny bridge between sigrok-cli and orbuculum

2020-07-02T18:59:39 < karlp> just repacking the LA output files to binary again is ok.
2020-07-02T18:59:58 < karlp> I just use tail -f <file from oocd> | orbuculum sort of thing anyway
2020-07-02T19:00:33 < jpa-> yeah, sigrok's usart decoder just can't keep up at 32MBaud (it's in python)
2020-07-02T19:00:54 < karlp> indeed.  pv is better in that regard as it catches first and then decodes behind
2020-07-02T19:01:56 < jpa-> looks like 8MHz does work with FT232H, so that's 2x better than what i had before :)
2020-07-02T19:01:58 < Cracki> you could dump undecoded samples, run that through your own script that handles blocks of samples at a time. the wait() api is more convenient for most purposes but not for performance
2020-07-02T19:02:23 < Cracki> numpy is fine for munching on samples
2020-07-02T19:02:49 < jpa-> yeah, it just sounds like too much of a project :)
2020-07-02T19:03:10 < Cracki> np.diff, np.nonzero, indexing are useful
2020-07-02T19:11:23 < jpa-> i should probably also add some kind of range support to orbcat channel specs; this looks so stupid: orbcat -c 10,"%6d " -c 11,"%6d " -c 12,"%6d " -c 13,"%6d " -c 14,"%6d " -c 15,"%6d " -c 16,"%6d " -c 17,"%6d " -c 18,"%6d " -c 19,"%6d " -c 20,"%6d\n"  > buf

2020-07-03T06:26:38 < rajkosto> chrome doesnt because they dont want you to have too many tabs (UI limitation of no scrolling or grouping for tabs reflects this)

2020-07-03T10:14:30 < mawk> he's watching reality tv
2020-07-03T10:14:36 < mawk> and using makeup
2020-07-03T10:15:03 < mawk> two telltale signs of being a girl
2020-07-03T10:18:09 < Steffanx> Did you make him go to dutchland yet?
2020-07-03T10:18:31 < mawk> we went to no man's land friesland several times
2020-07-03T10:18:55 < mawk> but a long time ago
2020-07-03T10:20:11 < mawk> even in friesland islands with a small boat

2020-07-03T10:28:35 < mawk> he doesn't want to
2020-07-03T10:29:11 < Cracki> *headscratch* brother(male), right wing, using makeup
2020-07-03T10:29:40 < mawk> lol
2020-07-03T10:30:17 < Cracki> the bundle of sticks has two meanings that may be just one
2020-07-03T10:30:22 < mawk> he uses makeup to hide skin imperfections because he's got an inferiority complex or something
2020-07-03T10:30:58 < Cracki> how old? still in puberty?
2020-07-03T10:31:26 < Cracki> if it's big pores on the face, removing junkfood from the diet would help
2020-07-03T10:31:35 < mawk> he's 22 I think
2020-07-03T10:31:40 < Cracki> close enough
2020-07-03T10:32:06 < Cracki> there are even people who are shy about their moles. I don't understand it. they're moles. you can play connect the dots with that.
2020-07-03T10:32:41 < mawk> lol
2020-07-03T10:32:50 < Cracki> maybe they're secretly raycis. moles mean you're 0.01% black... on the surface
2020-07-03T10:34:59 < Cracki> I can understand if it's a mole in the face but elsewhere, eh who cares
2020-07-03T10:36:48 < mawk> I think it's acnea scars
2020-07-03T10:37:01 < mawk> but not that bad
2020-07-03T10:37:30 < Cracki> how do people manage to get "scars" from acne?
2020-07-03T10:37:50 < Cracki> wait until you see the whites in their eyes, then lance it
2020-07-03T10:38:17 < Cracki> seems like people squeeze before it's advisable
2020-07-03T10:39:58 < mawk> maybe something to do with sun exposure when the wound is healing or something
2020-07-03T10:40:06 < Cracki> I've seen some people with horrible acne. they must be eating a dozen bags of chips a day
2020-07-03T10:40:07 < mawk> but I never got acne so I don't know
2020-07-03T10:40:14 < mawk> yeah
2020-07-03T10:40:26 < Cracki> that and/or not showering
2020-07-03T10:40:32 < Cracki> just a wet wash cloth isn't doing much
2020-07-03T10:40:37 < mawk> when my girlfriend had acne in her teens it was customary to prescribe high doses of birth control pills against acne
2020-07-03T10:40:45 < Cracki> hot shower approaching a sauna does good
2020-07-03T10:40:50 < mawk> today we now many girls developed cancer or something from that treatment

2020-07-03T10:43:25 < Cracki> my mother was crazy about keeping the bath clean... can't take a shower without her shrieking about wiping the tiles down
2020-07-03T10:43:32 < Cracki> like... WAT

2020-07-03T10:49:10 < mawk> yeah they tried to use it for everything
2020-07-03T10:49:48 < Cracki> because of shit like this I don't trust new drugs/medicines
2020-07-03T10:49:59 < Cracki> that includes gates foundation liquid microchips

2020-07-03T10:50:57 < mawk> so yeah apparently it causes brain cancer in higher doses
2020-07-03T10:51:06 < mawk> as well as giving men breast
2020-07-03T10:51:07 < Cracki> awesome
2020-07-03T10:51:19 < Cracki> explains a lot of The Current Year
2020-07-03T12:42:00 < jadew> most people do not scar from acnee
2020-07-03T12:42:19 < jadew> even bad one, I think it has to do with the type of skin you have
2020-07-03T12:42:58 < jadew> washing your face a lot might actually contribute to it
2020-07-03T12:43:19 < jadew> because if you remove the oil from your skin, your body will try to produce more
2020-07-03T12:44:13 < jadew> and a simple wash won't unclog your pores, so you'll be more at risk
2020-07-03T12:44:21 < karlp> no no, dr cracki says it's just from bad diet :)
2020-07-03T12:44:27 < jadew> washing with something that removes dead skin is a different thing tho

2020-07-03T13:04:34 < Cracki> ye, the scarring comes from how they handle the situation
2020-07-03T13:06:14 < jadew> might have to do with how deep their sebaceous glands go
2020-07-03T13:07:14 < jadew> when you're trying to pop the zit, you risk popping the gland
2020-07-03T13:08:25 < jadew> if the damage you make is deep, then the scar tissue that forms there will reflect in a deformation on the surface, while if you only damage the surface of the skin, it just falls off and regenerates
2020-07-03T13:39:46 < jadew> any ideas if those floppy disk to USB work with everything?
2020-07-03T13:40:01 < jadew> they seem to mention something about keyboards
2020-07-03T13:42:20 < Cracki> keyboards? what says that
2020-07-03T13:42:32 < Cracki> they should act like a mass storage device
2020-07-03T13:42:45 < jadew> the ads for the floppy disks "For Musical Keyboad"
2020-07-03T13:42:51 < Cracki> uhh
2020-07-03T13:43:06 < Cracki> do those "musical keyboards" also take regular thumb drives?
2020-07-03T13:43:14 < jadew> oh well, managed to format my floppy
2020-07-03T13:43:19 < jadew> it wasn't getting recognized
2020-07-03T13:45:01 < jadew> :/ looks like the floppy drive in my instrument isn't working anymore
2020-07-03T13:45:26 < jadew> I guess I'll get one of those musical keyboard adapters and hope it works
2020-07-03T13:45:40 < Cracki> is it a regular floppy drive with floppy bus?
2020-07-03T13:47:11 < jadew> IIRC, yeah
2020-07-03T13:47:21 < jadew> it's been a long time since I opened it up
2020-07-03T13:47:32 < jadew> I found one that doesn't mention midi keyboards
2020-07-03T13:47:35 < jadew> I'll get that one
2020-07-03T13:47:48 < Cracki> so... the plan is to replace the drive with something that turns usb MSD into floppy bus?
2020-07-03T13:48:04 < Cracki> or does the thing have a usb port (besides using floppies)
2020-07-03T13:48:21 < jadew> no, it just has a floppy disk
2020-07-03T13:48:39 < jadew> I'll get this: https://www.aliexpress.com/item/4001108295036.html
2020-07-03T13:48:57 < Cracki> what's the downside to getting an actual floppy drive for replacement
2020-07-03T13:49:01 < jadew> not sure what that ugly ass display does
2020-07-03T13:49:06 < Cracki> apart from still having to sling floppy disks
2020-07-03T13:49:12 < jadew> that's the only downside
2020-07-03T13:49:18 < jadew> floppies are difficult to come by
2020-07-03T13:49:32 < jadew> and I don't have a floppy drive on my PC, I have to use an USB one

2020-07-03T13:52:11 < jadew> heh, an actual floppy drive is double the price
2020-07-03T13:52:52 < jadew> found one without the display: https://www.aliexpress.com/item/32993297557.html
2020-07-03T13:53:14 < jadew> but I wonder what the buttons are for on the other one
2020-07-03T13:57:07 < dongs> ? what about it
2020-07-03T13:57:27 < jadew> ah, it seems that's there in order to create multiple images
2020-07-03T13:57:32 < dongs> yes
2020-07-03T13:57:39 < jadew> basically you can switch between "disks"
2020-07-03T13:57:41 < dongs> usuall you can put like disk0.img disk1.img etc into the usb
2020-07-03T13:57:42 < dongs> and you can switch
2020-07-03T13:57:43 < dongs> yea
2020-07-03T13:57:43 < jadew> dongs, you have that stuff?
2020-07-03T13:57:56 < dongs> i know someone with a simlar thing yeah
2020-07-03T13:58:01 < dongs> there's also some opensores projects to do this kidna shit
2020-07-03T13:58:03 < jadew> does the screen stay lit when you don't have an USB stick in?
2020-07-03T13:59:10 < dongs> the one i saw wasn't that particular one, so im not sure. 
2020-07-03T13:59:19 < dongs> why does it matter, you dont wanna tape it up or something?
2020-07-03T13:59:59 < jadew> it would look weird if it was always turned on, but I guess it doesn't matter
2020-07-03T14:00:18 < jadew> you said it creates some image files?
2020-07-03T14:00:20 < dongs> these things have been around for years tho
2020-07-03T14:00:25 < jadew> does that mean I need a program to access the contents?
2020-07-03T14:00:30 < dongs> it doenst create anything, you basically stick iamge files ON usb
2020-07-03T14:00:35 < dongs> in a format / filenames that it needs
2020-07-03T14:00:41 < dongs> and it will choose 1st one or 2nd one etc
2020-07-03T14:00:45 < dongs> you can cycle between by eject/load new one
2020-07-03T14:01:15 < dongs> iirc you called them FLOPPY00 or whaetver
2020-07-03T14:01:29 < jadew> yeah, but if you then stick the USB stick in a PC, you will see image files, not the actual files, right?
2020-07-03T14:01:37 < dongs> yes of course
2020-07-03T14:01:40 < dongs> it works on image files
2020-07-03T14:01:41 < dongs> only
2020-07-03T14:01:49 < jadew> I see
2020-07-03T14:02:05 < jadew> I thought it just exposes the file system on the stick
2020-07-03T14:02:42 < dongs> nah, that would be a waste of a stick

2020-07-03T14:03:30 < dongs> since 2009
2020-07-03T14:04:29 < jadew> oh well, guess I'll give it a try
2020-07-03T14:04:35 < dongs> you can get a display-less one that still has buttons
2020-07-03T14:04:40 < dongs> you'll just be switcfhing images blindly
2020-07-03T14:05:00 < jadew> I don't mind the display if it stays off when not in use
2020-07-03T14:05:09 < jadew> trying to find a review on youtube

2020-07-03T14:06:48 < jadew> yeah hehe
2020-07-03T14:06:48 < dongs> it emulates a USB floppy over USB by using USB sticks?
2020-07-03T14:07:03 < jadew> yeah
2020-07-03T14:07:55 < jadew> looks like the display stays on
2020-07-03T14:10:40 < dongs> looks like you can tell it to format 100 floppy images for you on insert
2020-07-03T14:10:44 < dongs> or maybe 1000
2020-07-03T14:10:47 < Cracki> you could put your own firmware on it
2020-07-03T14:11:14 < Cracki> so it turns the display off after a while

2020-07-03T20:24:08 < Mangy_Dog> having a bitwise connudrum and truth be told... im still really iffy on bitwise... So im tryign to toggle a single bit in a register byte (timer stuff in arduino) TCCR1B ^=(1<<ICES1); I just want to flip the state capture bit on rising to falling to rising with each interupt call....  from what i get that should work. But some one else is telling me that would also flip other bits in the byte
2020-07-03T20:24:18 < Mangy_Dog> confusing the hell out of me tbh
2020-07-03T20:25:04 < Mangy_Dog> would it flip other bits?
2020-07-03T20:25:34 < Mangy_Dog> ICES1 is bit 6
2020-07-03T20:27:32 < effractur> what is the size/singed/unsinged?
2020-07-03T20:28:16 < Mangy_Dog> 8
2020-07-03T20:28:28 < Mangy_Dog> its a register byte
2020-07-03T20:28:39 < Mangy_Dog> for timer control
2020-07-03T20:31:17 < effractur> that should work then i think
2020-07-03T20:31:38 < PaulFertser> Mangy_Dog: when you XOR with a value that has only one bit set, it's going to toggle only a single bit. Can you ask "some one else" why he or she thinks that it might affect the other bits?
2020-07-03T20:32:35 < Mangy_Dog> thats why it was confusing me
2020-07-03T20:32:53 < PaulFertser> Mangy_Dog: some hardware registers have special semantics, e.g. "write one to clear" ("w1c").
2020-07-03T20:33:29 < PaulFertser> Mangy_Dog: in case TCCR1B has one of those, your operation might affect them I'd say.
2020-07-03T20:34:08 < PaulFertser> But unlikely even in that case as an optimising compiler is likely to use "toggle one bit" instruction for that case.
2020-07-03T20:35:01 < PaulFertser> There're also "flag X can be cleared by reading register N" type of odd semantics. 
2020-07-03T20:40:33 < karlp> you're in the wrong channel, you should be in #avr or #arduino for your avr questions....
2020-07-03T20:41:30 < Steffanx> Or #avrs

2020-07-03T21:17:09 < Mangy_Dog> ?
2020-07-03T21:18:38 < zyp> yeah, the xor is gonna turn into a RMW operation

2020-07-03T21:18:55 < zyp> read-modify-write
2020-07-03T21:19:16 < Mangy_Dog> but only the bit i select?
2020-07-03T21:19:19 < zyp> read the old value, modify it to toggle a bit and write it back
2020-07-03T21:19:41 < zyp> it writes all bits back, both the one you toggled and all the unchanged ones
2020-07-03T21:20:03 < zyp> which means that if any of them was changed by hardware, you just wrote an outdated value back
2020-07-03T21:20:19 < Mangy_Dog> sorry im a bit pissed off tbh... ive just come to the conclusion that the person who said they were going to help me has basicly wasted mny entire day for what should have been 3 or 4 minutes worth of coding and my oven would have been done

2020-07-03T21:22:00 < Mangy_Dog> and im trying to tell them that each rising and dropping edge IS the zero cross point
2020-07-03T21:22:10 < Mangy_Dog> then they say it isnt

2020-07-03T21:23:00 < Mangy_Dog> but just noisy chinese ac stuff

2020-07-03T22:32:04 < Cracki> I see that you use ICR1 to capture the period, which should be mostly constant anyway. what you want is for the timer to be *cleared* upon zero crossing

2020-07-03T22:34:04 < Cracki> I'd set it up so the timer is cleared upon zero crossing, and then I'd just calculate OCR1A (duty cycle) based on the fair assumption that your mains is 50 or 60 hz, which means 16.6 or 20 ms
2020-07-03T22:34:26 < Cracki> what's the core frequency, 8, 16, 20 mhz?
2020-07-03T22:35:25 < Cracki> assuming 16 MHz and 256 prescaler, 16e6 / 256 / (50 hz *2) = 625 counts per half wave. you can set your duty cycle based on that
2020-07-03T22:36:09 < Cracki> (50 hz * 2 because just /50 hz gives you two half-waves)
2020-07-03T22:36:46 < Cracki> the WGM stuff is thus: WGM<timer number><bit number>
2020-07-03T22:36:57 < Cracki> so WGM1x is for timer 1
2020-07-03T22:37:13 < Cracki> WGM0x is timer 0, which you don't use, so stick with what you find for WGM1
2020-07-03T22:39:00 < Cracki> as for the targetAC_time calculation... you have all integers there. /100 will result in an integer again (no "decimals"), which is probably a very small number given the timer settings
2020-07-03T22:39:27 < Cracki> you could use floats there, but I'd rearrange this expression so division happens at last, all the addition and multiplication first
2020-07-03T22:40:47 < soreau> reminds me of my zero cross dimmer https://www.instructables.com/id/Intel-Edison-Controlled-AC-Dimmer/
2020-07-03T22:41:50 < Cracki> otoh those values are ints and they'll overflow quick, and for signed ints that's "undefined" (pracically predictable but bad for this expression)
2020-07-03T22:42:58 < Cracki> Mangy_Dog, also, since you have TCCR1B = 0, "set WGM02 to zero" is superfluous. the whole register is 0 already
2020-07-03T22:43:08 < Cracki> after clearing, set the bits you want to set. that's all
2020-07-03T22:47:37 < Cracki> WGM11 and WGM10 are in TCCR1A, if you need those
2020-07-03T22:48:07 < Cracki> I also think you want the COM1 bits because you want this timer to generate pwm output
2020-07-03T22:48:43 < Cracki> sure you can use the COMPA isr and set the pin manually
2020-07-03T22:51:36 < Cracki> assuming ICR1 measures half wave intervals, which should be around 625, and your duty cycle is expressed as percents, a good expression for OCR1A would be... OCR1A = ((uint32_t)(100 - dutyTrig) * ICR1) / 100;
2020-07-03T22:52:20 < Cracki> not sure what you're doing with newAC and oldAC. to me it looks like you're setting OCR1A = ICR1 + something, which should never trigger.
2020-07-03T22:57:31 < Cracki> ah, now I think I get it
2020-07-03T22:57:51 < Cracki> you're letting the timer run freely, and old/new are "timestamps"

2020-07-03T22:59:40 < Cracki> newAC_time and oldAC_time should be uint16_t then, and OCR1A = ICR1 + ((new-old) * (uint32_t)(100-dutyTrig)) / 100; // uint32 cast needed, or else the product overflows 16 bits (probable with expected values)
2020-07-03T23:03:22 < Cracki> (new-old is unsigned subtraction, that'll work fine through counter overflows, no worries there)
2020-07-03T23:05:42 < Cracki> tbh you could just take new-old, watch it, and if it's the predicted value period = (F_CPU / prescaler / (2*mains freq)), just use that fixed value: OCR1A = ICR1 + ((uint32_t)period * (100-dutyTrig)) / 100;

2020-07-03T23:25:19 < Mangy_Dog> soirry was afk eating supper
2020-07-03T23:25:52 < Cracki> about to do same
2020-07-03T23:25:56 < Mangy_Dog> actually i was thinking the same about using TCNT1-0 to reset at each cycle trigger
2020-07-03T23:26:03 < Mangy_Dog> =0
2020-07-03T23:26:16 < Mangy_Dog> and do away with the old v new stamps
2020-07-03T23:26:29 < Mangy_Dog> and just set the value where COMPA triggers
2020-07-03T23:26:57 < Mangy_Dog> a little less math and a little less cpu cycles
2020-07-03T23:27:33 < Mangy_Dog> i was also about to intergrate this into my heating cycle code
2020-07-03T23:27:37 < Mangy_Dog> well the calls
2020-07-03T23:27:55 < Mangy_Dog> it requires some editing as it was designed as a scheduled slow pwm before need to rearrange a few things

2020-07-04T03:42:39 < nn7> It looks like my code takes about 48k. The way the memory on this chip is laid out, all the small sectors are near the beginning which my code spans, so if I want to do my own writing to flash, I'm stuck with the big sectors.

2020-07-04T03:47:57 < Cracki> "linker script". cubemx generates it once and then tends to not touch it.
2020-07-04T03:48:08 < Cracki> the .ld file. you can mess with it to some extent.
2020-07-04T03:48:51 < nn7> ah, the _FLASH.ld?
2020-07-04T03:49:26 < nn7> there it is. beautiful, if a bit cryptic. :D
2020-07-04T03:49:40 < Cracki> look for "bare metal stm32". there are a few blog posts that also show simple linker scripts. that'll help you understand what's going on and how to change it
2020-07-04T03:50:01 < Cracki> https://jacobmossberg.se/posts/2018/08/11/run-c-program-bare-metal-on-arm-cortex-m3.html

2020-07-04T03:50:23 < Cracki> I've only touched it to reserve a few pages of flash for "eeprom emulation"
2020-07-04T03:50:42 < nn7> that's what I'm trying to do
2020-07-04T03:50:49 < Cracki> (I could have relied on it not touching the last few pages but that's safer)
2020-07-04T03:51:35 < Cracki> random commit of random person vaguely related https://gitlab.iri.upc.edu/humanoides/bioloid_stm32_fw/commit/34b0ea1cd3f312d95dd6f3ea24513e39e19a3cda
2020-07-04T03:51:36 < nn7> so I need to tell it to start flashing in a different place and I need to tell it to boot at that different place
2020-07-04T03:52:10 < Cracki> why do you have different sized pages?
2020-07-04T03:52:17 < Cracki> and why do you want the early pages?

2020-07-04T03:53:26 < Cracki> it might be possible for you to move the entry point but maybe it's also possible to make the linker put code "around" a space you reserved, allow it to start at the usual address but skip a range
2020-07-04T03:53:42 < Cracki> heh 128k
2020-07-04T03:53:50 < nn7> it's a huge chunk!
2020-07-04T03:53:55 < nn7> I only need to save 12 bits
2020-07-04T03:54:17 < nn7> I should have put a battery on Vbat and used the RTC backup registers
2020-07-04T03:54:40 < Cracki> was about to mention that but they're gone without vbat, quite "volatile"
2020-07-04T03:55:02 < nn7> <nod>
2020-07-04T03:55:25 < Cracki> hm, are you sure those are actually "flash pages", not some higher organization?
2020-07-04T03:56:47 < nn7> "A main memory block divided into 4 sectors of 16 KBytes, 1 sector of 64 KBytes, 3
2020-07-04T03:56:47 < nn7> sectors of 128 Kbytes (STM32F411xC/E)."
2020-07-04T03:56:54 < Cracki> meh
2020-07-04T03:57:01 < nn7> meh is correct
2020-07-04T03:57:54 < nn7> I mean, I can get away with this but there's some default configuration stuff that will never change. There's the risk that if I fill up my memory and need to erase and start over, I lose power and don't get to carry over the configuration variables.
2020-07-04T03:57:56 < Cracki> you could use the last two sectors. that still leaves you with 256k before that :D
2020-07-04T03:58:10 < nn7> and yes, the other option is to use the two 128k blocks
2020-07-04T03:58:12 < Cracki> yes, for that kinda fault tolerance you need two pages
2020-07-04T03:58:27 < nn7> which I can in this case since my code is currently a whopping 48k, but it's the principle.
2020-07-04T03:58:28 < Cracki> "x-cube-eeprom" for a reference (with a subtle bug or two)
2020-07-04T03:59:04 < Cracki> anyway, look into linker scripts. I think you can just reserve some of the early pages (not necessarily the first) and the linker will place code around it
2020-07-04T03:59:36 < Cracki> or you can look into what the option bytes can do for you in terms of moving the entry point and interrupt table or whatever
2020-07-04T04:00:29 < PaulFertser> nn7: example of using .ld script to reserve space https://github.com/Ralim/ts100/pull/655/commits/0d700669ef589abe90c3676d1fa1da16c94a5eb3
2020-07-04T04:00:44 < nn7> don't really see anything in the option bytes that allows me to move
2020-07-04T04:01:28 < nn7> PaulFertser, thanks!
2020-07-04T04:01:49 < PaulFertser> nn7: you can't move the vector table but you can make your special pages right after that I guess.
2020-07-04T04:01:53 < Cracki> 2.4 boot configuration > the CPU fetches the top-of-stack value from address 0x0000 0000, then starts code execution from the boot memory starting from 0x0000 0004.
2020-07-04T04:02:57 < Cracki> flash (0800xxxx) is aliased to 0000xxxx. someone mentioned "banked flash", where you can switch between banks to boot from, for safe firmware updates
2020-07-04T04:03:21 < PaulFertser> nn7: so you'll have the very first sector holding just the exception handlers table and waste the rest of its space, the next sector you can use for config, and the rest of the code can be located later. Since those will be different sections GDB's "load" will write them individually, hopefully preserving the config over reflashing.
2020-07-04T04:04:39 < PaulFertser> nn7: in that commit I reserve space at the end but I think if you just move it after .isr_vector that'll be what you're after.
2020-07-04T04:06:26 < nn7> Well, I think this is all over my head.
2020-07-04T04:06:47 < Cracki> start small, simple linker script, see what's happening
2020-07-04T04:07:33 < Cracki> try defining a range and then put one simple variable in there
2020-07-04T04:08:01 < Cracki> you define the range in the linker script, and the variable in your source code file gets an attribute to its declaration
2020-07-04T04:08:21 < Cracki> run it, check that its address is where you expect it
2020-07-04T04:09:04 < PaulFertser> I suggest inspecting the map file instead of running.
2020-07-04T04:09:11 < Cracki> when you've got that, you can see about moving the text section
2020-07-04T04:09:20 < Cracki> ye look at map file :D

2020-07-04T04:28:34 < Cracki> run it :D
2020-07-04T04:29:24 < Cracki> inspect the vector region of the map file, see what takes 408 bytes there
2020-07-04T04:29:40 < Cracki> (408 = 102 * 4)
2020-07-04T04:29:43 < nn7> I have no hardware at the moment.
2020-07-04T04:30:14 < nn7> I'm looking for a memory map
2020-07-04T04:30:46 < Cracki> according to ref manual section 10.2, 408 bytes should be correct
2020-07-04T04:31:15 < Cracki> last one is at 0194, +4 is 0198, which is 408 decimal
2020-07-04T04:32:34 < Cracki> if you know how to read a hex file, maybe check what values it has put at 0800 0000..08
2020-07-04T04:32:44 < Cracki> those should be what I quoted above, stack value and instruction pointer
2020-07-04T04:32:53 < nn7> so the hardware boot sequence is to look for the vector table at 0800 0000 and that tells it where the actual code is?
2020-07-04T04:33:04 < Cracki> if the shenanigans worked, it'll jump to the beginning of your FLASH region
2020-07-04T04:33:32 < Cracki> well the boot process uses boot0/1 to map flash, or ram, or ROM, into 0x0
2020-07-04T04:34:00 < Cracki> so it's looking at address 0 and 4 to get stack pointer and instruction pointer (after that is the vector table)
2020-07-04T04:34:09 < Cracki> and the instructino pointer should point to your FLASH region
2020-07-04T04:34:12 < nn7> do I need two copies of the vector table? One in the first section and another one in the main section?
2020-07-04T04:34:45 < Cracki> nah
2020-07-04T04:34:55 < Cracki> it belongs in the beginning of flash
2020-07-04T04:39:19 < nn7> that's the first 8 bytes of the .bin file?
2020-07-04T04:39:33 < Cracki> i... don't think so
2020-07-04T04:39:37 < nn7> that I want to check?
2020-07-04T04:39:59 < Cracki> I don't have a bin file to follow along, just a hex file, and I wasn't successful in finding what I'm looking for yet
2020-07-04T04:40:01 < nn7> I found the memory map but it doesn't detail the vectors.
2020-07-04T04:40:11 < nn7> oh alrighty
2020-07-04T04:40:37 < Cracki> I'm not all that familiar with how a cortex m starts
2020-07-04T04:40:50 < nn7> my hex file as a small chunk at the beginning and then nothing until 0010000 which seems to be right
2020-07-04T04:48:59 < Cracki> the beginning of my hex file is :02 0000 04 0800 F2. 04 means extended linear address, 0800 is the high two bytes (i.e. flash). following data...
2020-07-04T04:50:14 < Cracki> first bytes in my flash (I didn't do any messing around): 00A00020 61A90008 D1380008 D3380008
2020-07-04T04:50:40 < nn7> :/
2020-07-04T04:50:42 < Cracki> so what you see is 0x2000a000 for the stack address, and next is the reset handler at 0x080000a961
2020-07-04T04:50:53 < Cracki> so it jumps to a961 and runs code
2020-07-04T04:51:02 < nn7> ah it's backwards. that helps
2020-07-04T04:51:15 < Cracki> do you have a hex file? I'm not sure of the contents of a bin file in this context
2020-07-04T04:51:24 < Cracki> yes backwards, little endian
2020-07-04T04:51:32 < nn7> bin and elf
2020-07-04T04:51:34 < Cracki> i.e. big end is last
2020-07-04T04:52:09 < nn7> I can convert to Intel Hex
2020-07-04T04:53:32 < nn7> ok, my hex starts like yours
2020-07-04T04:53:48 < Cracki> btw, the a961 is odd, the lowest bit signals thumb mode (I think). the real address is a960, and that's labeled as the <Reset_Handler> in my .list file
2020-07-04T04:53:58 < Cracki> same in my map file

2020-07-04T04:54:26 < Cracki> so I would expect your reset handler to sit at... 0801xxxx
2020-07-04T04:54:36 < Cracki> because that's your FLASH region
2020-07-04T04:55:06 < Cracki> keep this open, intel hex files without syntax highlighting are murder https://en.wikipedia.org/wiki/Intel_HEX
2020-07-04T04:55:23 < nn7> https://paste.pics/027574a317729404376d1227fdedbe54
2020-07-04T04:55:30 < Cracki> open as text
2020-07-04T04:55:44 < Cracki> you don't need the whole left 3/4 of the view
2020-07-04T04:56:01 < nn7> oh I see

2020-07-04T04:56:53 < Cracki> so... 20020000 for stack
2020-07-04T04:56:55 < Cracki> good so far
2020-07-04T04:57:08 < Cracki> 112F0108 = 0x08012f11 for reset handler
2020-07-04T04:57:16 < nn7> https://paste.pics/2d0d28ed136a7a55a459733653314de5
2020-07-04T04:57:19 < Cracki> i.e. it's in 0801, which is what you wanted
2020-07-04T04:57:28 < Cracki> I quickly ocred your picture :D
2020-07-04T04:57:39 < Cracki> greenscreen on windows, with "office ocr" plugin
2020-07-04T04:58:13 < Cracki> so the operation succeeded. your code has moved
2020-07-04T04:58:35 < Cracki> congrats
2020-07-04T04:58:44 < Cracki> *greenshot
2020-07-04T04:58:47 < nn7> thanks! I'm still trying to parse this silly thing
2020-07-04T04:59:17 < nn7> ah, bytes are reversed as well
2020-07-04T04:59:40 < Cracki> all I'm going by is section 2.4 (for how it starts executing) and table 37 (for the vector table) https://www.st.com/resource/en/reference_manual/dm00119316-stm32f411xce-advanced-armbased-32bit-mcus-stmicroelectronics.pdf
2020-07-04T04:59:42 < nn7> awesome. Thank you very much Cracki!
2020-07-04T05:00:07 < Cracki> thank you, it's more fun to work a problem if the outcome doesn't affect me :D
2020-07-04T05:00:19  * nn7 is looking at reference manual
2020-07-04T05:00:27 < nn7> I've always wondered how to decode some of this stuff
2020-07-04T05:02:15 < nn7> "cpu fetches the top-of-stack value from address 0 then start code execution from boot memory starting from 0x04"
2020-07-04T05:02:39 < nn7> ok. This is starting to become less of a black box now
2020-07-04T05:02:51 < nn7> Success!
2020-07-04T05:02:55 < nn7> You're my new best friend.
2020-07-04T05:03:08 < Cracki> >_>
2020-07-04T05:06:03 < Cracki> how does your linker script look like now?

2020-07-04T05:08:00 < nn7> All I did was define a few more positions. The initial .ld had just RAM and FLASH, with FLASH taking up the whole 512k. I split it into RAM, VECTOR, E1, E2, E3, FLASH, E4.
2020-07-04T05:08:19 < nn7> and changed .isr_vector to write to >VECTOR instead of >FLASH
2020-07-04T05:10:16 < Cracki> my cubemx generated ld contains a a whopping ~200 lines
2020-07-04T05:10:41 < Cracki> the MEMORY part only has ram ccmram and flash tho
2020-07-04T05:10:57 < nn7> Mine is 180 lines
2020-07-04T05:11:09 < nn7> ... with a 25 line header

2020-07-04T22:11:08 < R2COM> and why need for .ARM.extab/exidx
2020-07-04T22:11:17 < zyp> exception handling stuff, probably not needed
2020-07-04T22:12:09 < zyp> that shit is pretty old, I just added shit until I got something that worked

2020-07-04T22:13:40 < zyp> instead of having a bunch of small parts for every supported part
2020-07-04T22:35:47 < R2COM> are the NULL statements inside interrupt vector array really necessary?
2020-07-04T22:36:02 < R2COM> most of them are proper handlers for various stuff
2020-07-04T22:36:06 < R2COM> but why NULL inserts

2020-07-04T22:42:14 < zyp> because those are unused vectors
2020-07-04T22:43:33 < R2COM> but dont just include unused vectors in vector table?
2020-07-04T22:43:49 < zyp> better call ARM and tell them that
2020-07-04T22:44:21 < R2COM> what i really mean is, if one removes "NULL" from that table, will it break something?
2020-07-04T22:46:20 < zyp> how do you think the vector table works?
2020-07-04T22:49:25 -!- leite [~leite@lollae.com] has quit [Remote host closed the connection]
2020-07-04T22:50:06 < zyp> when handling e.g. the systick interrupt, the cpu will look up the handler address from index 15 in the vector table
2020-07-04T22:50:15 < Cracki> it's not a list. things have to be at fixed positions.
2020-07-04T22:53:49 < zyp> the NULLs themselves are not important, those locations will never be read anyway so you can put whatever there

2020-07-05T01:59:51 < R2COM> like in pg. 209 with interrupt table they show physical addresses skipped
2020-07-05T02:00:02 < R2COM> and singe its 0x4 alignment maybe thats why table had to have NULL values

2020-07-05T17:01:07 < PaulFertser> Why the fuck did they censor some of the words? And what is the third one?
2020-07-05T17:13:09 < strata> wheel... of.... fortune!
2020-07-05T17:18:03 < Steffanx> lol PaulFertser. I wrote exactly, but decided to not to press enter. Because im a bit tired of this shit.
2020-07-05T17:19:30 < Steffanx> We wouldnt dare to write "nigger", so we write "n****r" because then no one knows we meant "nigger". fuck off.
2020-07-05T17:31:21 < strata> i'm sorry. not for being white. but for our mind virus infecting you all in UK/EU
2020-07-05T17:32:03 < strata> i didn't think it was possible for american idiocracy to spread to other countries... but it did.
2020-07-05T17:32:59 < PaulFertser> Truth to be told, there's certain validity in the argument that when you teach a NN on some generic content from the Internet, it ends up being somewhat hateful.
2020-07-05T17:33:14 < Steffanx> Yeah, i feel sad we "discovered" america back then strata :P
2020-07-05T17:34:10 < PaulFertser> So the community does need a more accurate and unbiased image set.
2020-07-05T17:34:35 < strata> Steffanx: we don't blame you for that. well... maybe the crazies here do.
2020-07-05T17:34:35 < Steffanx> Cant we drag america back into the sea strata?
2020-07-05T17:35:10 < Steffanx> Just drag america of its feet and back into the sea. Best solution for everything.
2020-07-05T17:35:24 < Steffanx> *push of its feet, drag back into the sea
2020-07-05T17:35:33 < strata> america is mostly ok. 99% of what you're seeing is gaslighting. in the _real_ america where i currently reside, it's been business as usual.
2020-07-05T17:35:49 < strata> we had fireworks, and big bonfires and cookouts and parties this weekend.
2020-07-05T17:36:04 < Steffanx> and "fuck covid-19" ?
2020-07-05T17:36:15 < strata> i ate my fried chicken and watermelon and cornbread under my neighbor's confederate flag. and listened to country music.
2020-07-05T17:36:39 < Steffanx> No guns in this story?
2020-07-05T17:36:54 < strata> i don't own guns. but most of my neighbors were firing off rounds all weekend yes.
2020-07-05T17:36:59 < Steffanx> haha
2020-07-05T17:37:06 < Steffanx> i knew it
2020-07-05T17:37:23 < PaulFertser> It's weird the paper itself https://arxiv.org/pdf/2006.16923.pdf has those words censored too. But other than that it looks sensible on the first glance.
2020-07-05T17:38:03 < strata> if anything, all the gaslighting by our media only helped strengthen the 4th of july celebrations. there were more fireworks this year than ever before. bigger parties. more 'murica.
2020-07-05T17:38:24 < strata> one of my neighbors said "we're doing it big this year because it might be the last one before the racists cancel it."
2020-07-05T17:39:01 < strata> i was like "... LOL are you sure you aren't from the internet?"

2020-07-05T17:48:48 < Steffanx> Still meeeh. PaulFertser. If you cant even use the words in proper context in a scientific paper... meeeh. :P
2020-07-05T17:51:21 < mawk> Steffanx: do you feel offended when I say "omg" on a sunday ???
2020-07-05T17:59:59 < Steffanx> i only feel offeded because its an awful yankee think to say

2020-07-05T19:40:42 < R2COM> thanks zyp
2020-07-05T19:41:28 < R2COM> zyp i now remember that long ago i used that probe!
2020-07-05T19:41:33 < R2COM> black magic probe with gdb only
2020-07-05T19:41:44 < R2COM> it worked just right and i did several projects with it
2020-07-05T19:42:06 < R2COM> then i switched somehow to that ST ide and didnt like it
2020-07-05T19:42:36 < R2COM> then recently to VisualGDB at beginning i liked it, but after i wanted to build stripped projects i noticed weird stuff 
2020-07-05T19:42:59 < R2COM> like for example, the system didnt like my "__bss_start" ... it was throwing undefined reference
2020-07-05T19:43:09 < R2COM> it wanted me to do "__bss_start__" then it was OK
2020-07-05T19:43:28 < R2COM> OR, i had to use PROVIDE(__bss_start__ = __bss_start);

2020-07-05T19:44:02 < R2COM> so at times when i start using some graphical IDE in middle of something i start thinking that again simple gdb in command mode never has any weirdenss and just works
2020-07-05T19:44:40 < R2COM> zyp the only disadvantage is, unlike in IDE debugger, in gdb console you cannot see cool stuff like..i dont know... snapshot of hardware registers at same time, or many variables at same time... what are your thoughts on that?

2020-07-05T20:38:04 < zyp> hrm
2020-07-05T20:38:32 < zyp> when I dicked around with usb before, I managed to crash the host usb stack several times
2020-07-05T20:38:58 < zyp> but that's not so bad as now that I'm dicking around with pcie and crashing the entire host
2020-07-05T20:45:30 < jpa-> heh, worst that i've managed to do with usb is just to make individual usb drivers hang
2020-07-05T20:45:42 < Steffanx> lunix, macos or windows?
2020-07-05T20:45:47 < jpa-> i.e. got a zombie device that cannot be removed, but other devices still worked
2020-07-05T20:47:17 < zyp> jpa-, in my usual failure case, existing devices keeps working, but host refuses to enumerate new ones
2020-07-05T20:47:39 < zyp> also
2020-07-05T20:47:43 < zyp> «The VFIO driver is an IOMMU/device agnostic framework for exposing direct device access to userspace, in a secure, IOMMU protected environment.»
2020-07-05T20:48:05 < zyp> apparently secure doesn't include preventing hangs
2020-07-05T20:48:36 < Steffanx> so lunix it is ;)
2020-07-05T20:48:51 < zyp> for pcie? yeah

2020-07-05T20:49:29 < zyp> Steffanx, still toying around with this thing: https://bin.jvnv.net/file/0vD5z.jpg
2020-07-05T20:49:39 < Steffanx> oh you received it
2020-07-05T20:49:55 < zyp> quite a while ago
2020-07-05T20:50:09 < Steffanx> oh lol, i was still at the "i order this and this" point :P
2020-07-05T20:50:59 < zyp> vivado is fucking slow, especially running on a J4105, but otherwise it works fine
2020-07-05T20:52:20 < zyp> haven't really tried running anything custom with it yet, just the litex example built with a couple different risc-v cpus
2020-07-05T20:53:34 < zyp> so far I've mostly been trying to figure out how everything in pcie fits together and how to interface with it on the host side
2020-07-05T20:55:16 < zyp> memory mapped IO is pretty straight forward and I think I understand how to deal with interrupts and DMA as well
2020-07-05T20:55:37 < zyp> although the code that hung the host was supposed to run a dma job and send me an interrupt once complete :p
2020-07-05T20:56:32 < zyp> or something

2020-07-05T21:51:00 < qyx> is it usable?
2020-07-05T21:53:25 < effractur> they are quite okay ish just shitty sinlethreaded performance
2020-07-05T21:54:40 < effractur> and no avx etc
2020-07-05T21:57:10 < qyx> avx?

2020-07-05T21:57:36 < effractur> modern vector instructions

2020-07-05T22:46:59 < emeb> gah - the way this Siglent waveform generator changes frequency step size when crossing over the 1MHz boundary is driving me nuts.
2020-07-05T22:54:18 < Steffanx> dont go nuts emeb
2020-07-05T22:54:50 < Steffanx> why dont you enter the value manually me emeb?
2020-07-05T22:55:20 < zyp> fucking vivado is so sloooow
2020-07-05T22:56:23 < zyp> emeb, how do you like the opensource tools?
2020-07-05T22:56:33 < Steffanx> Why do you run vivivado on your target? Cant you run it from your own pc?
2020-07-05T22:56:43 < zyp> no vivado on macos
2020-07-05T22:56:53 < Steffanx> i bet even in a vm it would be faster.
2020-07-05T22:56:58 < emeb> Steffanx: slewing the frequency around +/- 1MHz while testing some SDR stuff and every time I cross 1MHz the stepsize changes. Grumble.
2020-07-05T22:57:07 < zyp> Steffanx, sure, or my linux server
2020-07-05T22:57:09 < emeb> zyp: I'm very happy with the FOSS tools 
2020-07-05T22:57:34 < zyp> Steffanx, I'm just too fucking lazy to deal with remote building
2020-07-05T22:57:57 < emeb> They run fast and produce decent output. The recent DSP additions are good at handling my signal processing constructs - multipliers are properly inferred.
2020-07-05T22:58:57 < Steffanx> hmm, mine does not seem to do that emeb. or im misunderstanding. When enter 1MHz, and change it in 10 Hz steps it will keep the 10Hz step. 
2020-07-05T22:58:58 < emeb> Takes less than a minute to synthesize my design on the i5 machine, and I can even synthesize on the RPi Zero if needed. It's crazy.
2020-07-05T22:59:09 < Steffanx> SDG2042X that is
2020-07-05T22:59:29 < zyp> since I'm using litex, it doesn't really matter that much what toolchain it calls behind the scenes as long as it's available
2020-07-05T22:59:30 < emeb> Steffanx: SDG1025 here.
2020-07-05T22:59:48 < zyp> the problem is just that vivado is a hassle to have available and it's slow as well
2020-07-05T23:00:13 < emeb> zyp: vivado is a huge PITA. What chips are you targeting?
2020-07-05T23:00:15 < zyp> I just built a minimal config for this thing, without pcie and ddr3, still took 4:40
2020-07-05T23:00:24 < zyp> xc7a200t
2020-07-05T23:02:22 < emeb> Ah - haven't done any Artix stuff. I've used Zynq and it's a slog to work through all the configuration of the PS and PL stuf
2020-07-05T23:02:50 < zyp> I'm gonna look into the free tools for that also later, but I don't think it'll do pcie any time soon, which is what I'm playing with now
2020-07-05T23:03:09 < emeb> But the absolute worst part is that the huge wad of miscellaneous design files that Vivado spews out is very difficult to put under configuration control.
2020-07-05T23:03:50 < zyp> luckily I'm not using vivado in that sense, just building with it
2020-07-05T23:04:29 < emeb> oh - so the design flow just hands it some input and it maintains no state between runs?
2020-07-05T23:04:46 < zyp> litex is generating or bundling whatever files vivado needs
2020-07-05T23:04:57 < emeb> that's cool
2020-07-05T23:05:11 < zyp> and throws all output into a build directory, so it doesn't clutter up everything else
2020-07-05T23:06:58 < zyp> sometimes I wish it did a bit more dependency tracking to avoid regenerating unnecessary stuff
2020-07-05T23:07:28 < emeb> Must be nice. I assume all the Litex stuff is derived from some easily identifiable source code so it's not difficult to put into some version tracking system?
2020-07-05T23:07:46 < zyp> yes
2020-07-05T23:08:22 < zyp> https://github.com/litex-hub/litex-boards/blob/master/litex_boards/targets/acorn_cle_215.py <- I'm building this, with a couple of modifications

2020-07-06T14:34:33 < tctw> how's coviding?
2020-07-06T14:36:52 < PaulFertser> Years ago one of my students bought a cheap rtlsdr device from ebay/ali. But it didn't work at all, not detected on the USB bus even so he gave it to me so that I took a look. I found that a via from the 5 V Vcc PCB pad/contact to the other side of the board was just not conducting at all. He was so demotivated by the trivialness of the fix that he never took the device back.
2020-07-06T14:37:11 < jadew> Laurenceb, thanks, which version?
2020-07-06T14:37:21 < jadew> R2 or mini?
2020-07-06T14:37:47 < jadew> ah, they both have similar input characteristics
2020-07-06T14:38:02 < Laurenceb> R2 i think... its packed away in a box..
2020-07-06T14:38:17 < jadew> Laurenceb, what frequency are your balloons operating on?
2020-07-06T14:38:25 < Laurenceb> 434mhz
2020-07-06T14:38:32 < jadew> that's good, thanks
2020-07-06T14:38:43 < Laurenceb> its legal for unlicensed use from balloons basically everywhere
2020-07-06T14:39:08 < PaulFertser> Do you use APRS?
2020-07-06T14:39:27 < Laurenceb> nope, very poor aprs in uk tbh
2020-07-06T14:39:55 < Laurenceb> also it doesnt seem to be legal for unlicensed balloon use
2020-07-06T14:40:36 < PaulFertser> Sucks
2020-07-06T14:40:40 < Laurenceb> in the uk and much of europe
2020-07-06T14:40:46 < jadew> do you normally use a LNA with the receiver, or is the SDR enough?
2020-07-06T14:41:03 < Laurenceb> people have switched between aprs and 434mhz based on geofence
2020-07-06T14:41:13 < Laurenceb> jadew: lna is normally not needed
2020-07-06T14:41:30 < jadew> I see, thanks
2020-07-06T14:41:41 < Laurenceb> I do have a long yagi with lna built in for receiving really weak signals close to horizon
2020-07-06T14:42:17 < PaulFertser> Laurenceb: what's the current best place to read about modern GNSS receivers that work properly above 20 km?
2020-07-06T14:42:30 < Laurenceb> not sure tbh
2020-07-06T14:42:35 < Laurenceb> ublox works
2020-07-06T14:43:35 < PaulFertser> You know ublox had many generations over the years with different capabilities and firmware.
2020-07-06T14:43:51 < Laurenceb> yeah I've only used >ublox4
2020-07-06T14:43:51 < PaulFertser> And aren't they bought by mediatek or something?
2020-07-06T14:44:04 < Laurenceb> maybe, ublox8 still works fine
2020-07-06T14:45:19 < PaulFertser> "MAX-M5Q is a standalone GNSS module from ublox that - supports concurrent GNSS navigation based onthe MT3333 chip. With the exceptional utilization of GPS and GLONASS simultaneously, MAX-M5Q can enhance the position availability in harsh GNSS satellite visibility conditions or at high latitudes, e.g. in polar regions."
2020-07-06T14:45:52 < Laurenceb> iirc that has been used for balloons without issue
2020-07-06T14:46:01 < Laurenceb> ask on #highaltitude
2020-07-06T14:47:09 < PaulFertser> ok thnx
2020-07-06T14:48:13 < Laurenceb> tbh I got bored of ballooning in 2018 as all the real pro guys seemed to have left and there wasnt much interesting or new happening
2020-07-06T14:48:42 < PaulFertser> So what are you into now?
2020-07-06T14:48:45 < Laurenceb> but there does seem to be some new stuff happening now, maybe there will be another conference, the conference kind of petered out 
2020-07-06T14:49:03 < Laurenceb> I'm working on stratospheric solar power - balloon based
2020-07-06T14:49:20 < Laurenceb> but not the "fix a rpi to muh balloon" stuff
2020-07-06T14:50:17 < Laurenceb> I'd be interested to find out whats happening with Loon, some Lon guys turned up to one of the conferences
2020-07-06T14:50:24 < specing> babbyloon
2020-07-06T14:50:34 < Laurenceb> lol
2020-07-06T14:50:51 < Laurenceb> I dont understand why loon is taking so long tbh
2020-07-06T14:51:07 < Laurenceb> guess google isnt prepared to commit, its an all or nothing system
2020-07-06T14:51:55 < Laurenceb> several thousand are needed for 100% coverage
2020-07-06T14:52:16 < Laurenceb> but it can work with unmodified smartphones so btfo's starlink
2020-07-06T14:53:04 < Laurenceb> most people who could use one of these services could not afford a starlink terminal
2020-07-06T14:54:49 < Laurenceb> but there is the same availability issue with starlink, the current constellation is useless for consumers as it will drop out all the time
2020-07-06T14:54:59 < specing> maybe google realised that there's no money in advertising shit to random african tribes
2020-07-06T14:55:18 < Laurenceb> lol yeah
2020-07-06T14:56:28 < Laurenceb> which begs the question who the market for starlink is
2020-07-06T14:56:45 < Laurenceb> maybe musk thinks he can undercut wired network providers
2020-07-06T14:56:48 < specing> no
2020-07-06T14:56:59 < specing> I know what it is
2020-07-06T14:57:05 < Cracki> the market is low latency
2020-07-06T14:57:14 < Cracki> hft will pay for this
2020-07-06T14:57:16 < specing> he wants to shroud the sky so that astronomers can't see shit anymore
2020-07-06T14:57:26 < specing> so he gets contracts to launch telescopes into orbit
2020-07-06T14:57:47 < specing> that's why it's called star link
2020-07-06T14:57:53 < specing> it breaks the link to stars
2020-07-06T14:58:16 < Laurenceb> google loon patents are full of all optical free space networking shit that would never work irl, its like they are all smoking weed
2020-07-06T14:58:44 < Laurenceb> even starlink had to drop free space optical links (not all optical networking in the atmosphere)
2020-07-06T14:59:50 < Laurenceb> if they wanted a sane backhaul system they could use 24GHz highly directional beams or any number of off the shelf sane methods for loon

2020-07-06T15:12:12 < jadew> Laurenceb, do you think balloonists would fork $100+ for a good limiting LNA, or are they like ham operators which would rather buy $4 crapjobs from china?
2020-07-06T15:12:47 < jadew> I'm trying to identify the markets for what I made
2020-07-06T15:13:37 < jadew> it's basically great for most people using SDR receivers and also needing gain on the input, but I think the price rules out a huge chunk of that category
2020-07-06T15:14:17 < Laurenceb> the second one mostly

2020-07-06T15:14:45 < jadew> so they wouldn't spend the money?
2020-07-06T15:15:48 < jadew> for example, this thing that I made would work great with the airspy, because it would provide both excellent NF and it would protect it from getting fried
2020-07-06T15:16:21 < jadew> as opposed to $4 shits, which would be able to fry them just by oscillating if you hold your hand wrong
2020-07-06T15:16:45 < Laurenceb> check out habamp by upu
2020-07-06T15:16:57 < jadew> checking
2020-07-06T15:17:59 < Laurenceb> this has already been done
2020-07-06T15:18:40 < jadew> the output power of that thing is higher than what most SDRs can take tho
2020-07-06T15:18:55 < jadew> the NF is in the same ballpark as my device
2020-07-06T15:19:02 < jadew> also, cheap construction
2020-07-06T15:19:55 < jadew> and my thing has ~37 dB of gain at 433 MHz
2020-07-06T15:21:14 < dongs> dont listen to laurence/b/ he jsut wants cheap GPL shit
2020-07-06T15:22:20 < jadew> heh, well he has insight into what that particular market thinks like
2020-07-06T15:24:32 < jadew> the output power of that amplifier is higher than 20 dBm
2020-07-06T15:24:52 < jadew> P1dB sits at 20, so the saturated power is higher
2020-07-06T15:25:31 < jadew> that means it can deliver 15 to 40 times the maximum power your SDR can take
2020-07-06T15:25:58 < jadew> most SDR receivers have a maximum input power of 10 dBm or less
2020-07-06T15:31:13 < jadew> that one is filtered, but you could still fry the SDR if you operated a walkie talkie near it

2020-07-06T16:41:44 < jadew> there was nothing wrong with their scanner in the previous years, when they only spent ~1 million dollars on shit (much of it on hotel accommodations and on-plane internet connections)
2020-07-06T16:42:05 < jadew> but in this case the total seems to be above 7 million
2020-07-06T16:42:18 < jadew> and somehow, the scanner did a bad job...
2020-07-06T16:43:13 < jadew> those are million dollars btw

2020-07-06T21:25:49 < fenugrec> englishman, made a ghetto stand for the microscope : https://imagebin.ca/v/5SW812dR3QOs
2020-07-06T21:26:07 < zyp> nice
2020-07-06T21:32:03 < emeb> cool microscope stand. I've got a surplus microscope that my wife found in the trash at work. Needs a stand and I've never gotten around to finding one.
2020-07-06T21:35:24 < zyp> hmm
2020-07-06T21:36:04 < zyp> playing with a samd21, initial impression is mixed
2020-07-06T21:36:21 < emeb> I tried that a long time ago.
2020-07-06T21:36:55 < emeb> had a heck of a time getting even simple stuff working without a deep dive into the Atmel libraries
2020-07-06T21:37:16 < zyp> ah, I'm not planning to use those, I'm looking at adding laks support
2020-07-06T21:37:39 < emeb> right
2020-07-06T21:38:19 < emeb> IIRC the system flash/rom startup code does a checksum before running the main user code
2020-07-06T21:38:28 < fenugrec> emeb, hope you have the focusing mount for it, they're surprisingly expensive
2020-07-06T21:38:30 < zyp> so I'm currently looking at some of the register definitions, and for some reason there's a bunch of 8-bit registers
2020-07-06T21:38:45 < zyp> emeb, they do? you're not confusing that with nxp?
2020-07-06T21:38:59 < emeb> fenugrec: yeah, got that and one of the metal arms. Just missing the stand.
2020-07-06T21:39:10 < emeb> zyp: could be.
2020-07-06T21:39:40 < zyp> I've built and loaded a firmware with an empty main, which seems to work just fine
2020-07-06T21:39:58 < emeb> nice
2020-07-06T21:40:08 < emeb> next up - flashy LEDs
2020-07-06T21:40:16 < zyp> and the sections are matching too, so it doesn't look like the debugger has patched in a checksum for me
2020-07-06T21:40:25 < zyp> like it would on lpc
2020-07-06T21:40:30 < emeb> ok - brainfart
2020-07-06T21:41:03 < emeb> I do recall that the GPIO and fancy universal serial peripherals were not intuitive to my STM32-addled brain.
2020-07-06T21:42:23 < zyp> I'm looking at the power manager, which seems analogous to RCC and I'm not a big fan of how they've got a mix of 8- and 32-bit registers
2020-07-06T21:43:12 < zyp> not that it really matters as long as I just make a matching definition
2020-07-06T21:44:09 < zyp> looks like all peripherals except the ones on APBC defaults to on, so I might not have to touch it yet anyway
2020-07-06T21:44:33 < zyp> gpio looks to be on APBB
2020-07-06T21:45:52 < emeb> good start. you'll be blinking before we know it.
2020-07-06T21:46:53 < emeb> ISTR that I was stymied because I couldn't find anything equivalent to the STM32 CMSIS headers with all the peripherals defined in one place.
2020-07-06T21:47:22 < zyp> gpio block looks pretty plain, there's DIR and OUT registers, that each has additional clear/set/toggle registers
2020-07-06T21:47:25 < zyp> and then IN of course
2020-07-06T21:47:28 < emeb> Had to download their big wad of libraries and grovel through it to find where to poke things...
2020-07-06T21:48:19 < zyp> but nothing like BSRR that can atomically set specific bits
2020-07-06T21:48:32 < zyp> I mean, set and clear on the same cycle
2020-07-06T21:48:37 < emeb> ya
2020-07-06T21:48:55 < zyp> then again, stm32 doesn't have toggle
2020-07-06T21:49:13 < zyp> and it can always be approximated with toggle
2020-07-06T21:49:52 < emeb> so my latest project in FPGAs is an ice40 up5k hanging off an RPi GPIO header. Learning to use all the Linux stuff to talk to it.
2020-07-06T21:49:53 < zyp> e.g. something like OUTTGL = (IN & mask) ^ value;
2020-07-06T21:49:57 < emeb> that's a hoot.
2020-07-06T21:50:16 < zyp> yeah, I've read the stuff you wrote in the other channel
2020-07-06T21:50:24 < zyp> sounds pretty fun
2020-07-06T21:50:33 < emeb> It's starting to work the way I want.
2020-07-06T21:50:48 < emeb> doing audio processing in user space 
2020-07-06T21:51:20 < emeb> wanted to have a "big loop" structure with the audio buffer handling in background while the foreground handles user interface.
2020-07-06T21:51:31 < emeb> got that working with pthreads this morning. pretty easy.
2020-07-06T21:51:45 < zyp> how are you doing user interface?
2020-07-06T21:51:59 < emeb> ATM it's just keyboard + text output.
2020-07-06T21:52:10 < zyp> ah
2020-07-06T21:52:25 < emeb> may strap on a SPI LCD + buttons & encoder tho.
2020-07-06T21:52:36 < emeb> shouldn't be too hard - lots of extra GPIO.
2020-07-06T21:53:00 < zyp> :)
2020-07-06T21:57:58 < ds2> why GPIOs?
2020-07-06T21:58:18 < fenugrec> not sure I want to see what a "strap on SPI LCD" looks like
2020-07-06T22:00:04 < emeb> fenugrec: you've got an interesting way of looking at things.
2020-07-06T22:01:08 < ds2> emeb: why GPIOs (vs I2S)?
2020-07-06T22:01:45 < zyp> for buttons, presumably
2020-07-06T22:01:51 < emeb> yep
2020-07-06T22:02:02 < emeb> don't need wide bandwidth for that.
2020-07-06T22:02:12 < emeb> and already using the I2S for the audio interface.
2020-07-06T22:02:22 < ds2> thought you were taking in audio from the FPGA?
2020-07-06T22:02:28 < emeb> ds2: yes
2020-07-06T22:02:45 < ds2> so you are sending audio via GPIO?
2020-07-06T22:02:49 < emeb> no
2020-07-06T22:03:13 < emeb> audio goes via I2S. GPIO is just for configuring the FPGA and user interface stuff.
2020-07-06T22:03:22 < ds2> Ohhhh
2020-07-06T22:03:32 < ds2> so the FPGA does speak I2S too?
2020-07-06T22:03:37 < emeb> yes.
2020-07-06T22:03:59 < emeb> FPGA emulates a standard codec - has both I2C and I2S interfaces so it looks like a WM8731
2020-07-06T22:04:14 < emeb> and I can use normal ALSA drivers to do my baseband interface.
2020-07-06T22:04:26 < ds2> the ice40 has OD IO?
2020-07-06T22:04:30 < emeb> yep
2020-07-06T22:04:41 < ds2> nice
2020-07-06T22:04:56 < emeb> got a simple little I2C slave that only takes about 89 LCs in the FPGA
2020-07-06T22:04:58 < ds2> know if the ice40 also has LVDS IO?
2020-07-06T22:05:07 < emeb> It doesn't have LVDS
2020-07-06T22:06:33 < ds2> blah so much for trying the 1bit ADC on the icestick
2020-07-06T22:06:55 < emeb> ds2: you can fake it with an external comparator.
2020-07-06T22:07:15 < emeb> sot23-5 package. simple.
2020-07-06T22:07:39 < emeb> I'm doing PDM audio output on this - sounds "good enough".
2020-07-06T22:08:14 < ds2> *nod* apparently a LVDS input plus some passives would work as a ADC
2020-07-06T22:08:25 < emeb> yes - I've seen it done.
2020-07-06T22:08:35 < ds2> was a fun thing I came across... thought it would be a good use for the icestick
2020-07-06T22:08:52 < emeb> the ice40 does have differential pair I/O, but they're not internally linked to a true comparator.
2020-07-06T22:13:23 < zyp> emeb, here you go: https://bin.jvnv.net/file/R3mai.mp4

2020-07-06T22:16:28 < strata> lulz
2020-07-06T22:16:53 < strata> how to DoS lieUNIX SBC
2020-07-06T22:16:58 < zyp> the problem is rather that laks needs more work on the build system side to handle building different stuff for different targets
2020-07-06T22:17:08 < zyp> hmm
2020-07-06T22:17:31 < zyp> although gpio is header only, so I should get away with only ifdef include actually
2020-07-06T22:18:19 < emeb> laks grows to take over the world
2020-07-06T22:18:25 < emeb> laks all the processors
2020-07-06T22:18:51 < zyp> well, yeah, I already have some preliminary risc-v support somewhere too :)
2020-07-06T22:19:10 < emeb> not surprised.
2020-07-06T22:19:22 < zyp> I had it running on a softcore on the colorlight board a couple of months ago
2020-07-06T22:19:23 < emeb> I've had fun doing C coding on risc-v for FPGAs.
2020-07-06T22:19:48 < emeb> it's cool to make your own peripherals from scratch.
2020-07-06T22:19:48 < emeb> do exactly what you want.
2020-07-06T22:19:52 < zyp> and now I've also got a gd32v so I have a more fixed risc-v target I can support
2020-07-06T22:19:58 < zyp> yeah
2020-07-06T22:20:30 < emeb> wonder if picorv32 would fit into my SDR project... :P
2020-07-06T22:20:51 < zyp> and with the pcie stuff I've been playing with, I'm planning to add support for building laks-based stuff for linux userland, using peripherals on the fpga via memory mapped IO over pcie
2020-07-06T22:21:05 < emeb> *cough*
2020-07-06T22:22:05 < zyp> hmm?
2020-07-06T22:22:25 < emeb> sounds like fun.
2020-07-06T22:23:24 < emeb> I know too many ppl who are hard-core kernel coders. when one mentions userland memory-mapped I/O access they all get the vapors.
2020-07-06T22:24:19 < zyp> well, sure, but writing a kernel driver isn't really interesting either way
2020-07-06T22:24:29 < emeb> I hear that.
2020-07-06T22:24:52 < emeb> it's why I spent my time emulating a codec that already had a driver
2020-07-06T22:25:17 < zyp> the interesting part is that I can run and debug a firmware easily, and then when it works I just build it for the cpu it's actually gonna run on
2020-07-06T22:25:18 < emeb> easier to do it in hardware than to try figuring out the kernel arcana.
2020-07-06T22:26:10 < zyp> since I can do memory mapped IO over pcie, it can talk to the peripheral just as if it were running on a cpu next to the peripheral
2020-07-06T22:26:16 < emeb> yup
2020-07-06T22:26:33 < emeb> main trouble is IRQ handling.
2020-07-06T22:27:02 < emeb> done in hardware on the embedded stuff - how will your OS-based development environment handle that?
2020-07-06T22:27:13 < zyp> eventfds, apparently
2020-07-06T22:28:09 < zyp> both the UIO and VFIO frameworks signals IRQs via eventfds
2020-07-06T22:28:51 < zyp> so I guess I'd have a glue layer calling poll() or select() to wait for IRQs
2020-07-06T22:29:16 < zyp> perhaps in a different thread so they can preempt other code
2020-07-06T22:29:25 < emeb> ic
2020-07-06T22:29:45 < emeb> pthreads turned out to be a lot easier than I feared.
2020-07-06T22:30:12 < zyp> on the other hand, I tend to use polling more than interrupts, so irq support is not super important at the moment
2020-07-06T22:30:29 < emeb> just put all the background processing I'd normally do via IRQs into its own thread and start it up.

2020-07-06T23:54:28 < zyp> usb chapter has seven register summary tables in total, but only one address listed in the peripheral table
2020-07-06T23:55:26 < zyp> looking closer, two of them are descriptors you put in ram, and the other five describe registers starting at the same address
2020-07-06T23:56:30 < zyp> the three first are common, device and host blocks, host and device are overlapping since only one will be used at a time, and they are both interleaved with registers from the commong block
2020-07-06T23:56:53 < zyp> and the last two are pipe/endpoint registers for host/device mode, also overlapping, starting at offset 0x100
2020-07-06T23:58:03 < zyp> dwc_otg also has that many blocks, but I don't think it interleaves them like that :)
--- Day changed Tue Jul 07 2020
2020-07-07T00:06:01 < zyp> apparently it's a HS capable core, but it only has a FS PHY and external PHYs doesn't seem to be supported

2020-07-07T00:56:07 < karlp> emeb: I'm not sure I follow, you made your fpga looklike an existing codec, so where do you do the extra stuff?
2020-07-07T00:57:01 < emeb> karlp: the I2S and I2C interfaces hook up to a decimating downconverter in the FPGA fabric.
2020-07-07T00:57:09 < emeb> instead of to audio ADCs/DACs
2020-07-07T00:57:34 < emeb> and I have a separate SPI control port that manages the downconverter - sets frequency, etc.
2020-07-07T00:58:07 < karlp> riiiigt. ok, the codecp ortion is just one bit, no problme
2020-07-07T00:58:29 < emeb> I sniffed the I2C and I2S buses on the RPi while driving a normal audio interface so I only handle messages to the config regs and at rates the driver uses.

2020-07-07T03:38:11 < jadew> the engineers are top notch, but the products are crap

2020-07-07T03:38:27 < jadew> my server is a mac mini and I just opened it for the first time
2020-07-07T03:39:06 < jadew> they made it difficult to access just because they wanted to have a round hole in the bottom, not square
2020-07-07T03:39:25 < jadew> on the other hand, the engineers did a great job with that and designed it really well
2020-07-07T03:39:39 < jadew> the whole thing is properly ventilated by a single fan
2020-07-07T03:40:06 < jadew> they did a really good job with the air routing

2020-07-07T03:45:17 < aandrew> yeah they seem to give the artsy guys the first kick, then pass it off to engineering to make it work, who push back on the art guys, who make aesthetic changes to accomodate what the engineers need, then back and forth
2020-07-07T03:46:01 < jadew> yeah, they seem to care more about form than function
2020-07-07T03:46:14 < jadew> I guess that works for them
2020-07-07T03:46:29 < aandrew> well I'd disagree there -- is there anything that really doesn't function?

2020-07-07T03:46:59 < aandrew> I mean they make shitty mistakes on some lines like the CPUs not cooling and throttling back
2020-07-07T03:47:00 < jadew> for one, there's no information on the boot screen on how to enter bios
2020-07-07T03:47:10 < aandrew> but generally speaking I think they hit the balance more correctly than not
2020-07-07T03:47:14 < jadew> second of all, the keyboard only works in one of the USB ports, not in the others

2020-07-07T03:48:10 < jadew> when this failure happened all I could see was a white screen followed by a black screen
2020-07-07T03:48:19 < jadew> no information or indication of what might be wrong
2020-07-07T03:49:16 < jadew> they've sacrificed functionality for what it looks like
2020-07-07T03:49:21 < jadew> a lot of it IMO

2020-07-07T11:17:10 < Cracki> (which is why they axed nuclear power, so we have to burn more coal to compensate)

2020-07-07T11:32:47 < Cracki> yes I'll try to keep it in mind
2020-07-07T11:33:14 < PaulFertser> Cracki: that picture is only half-true.
2020-07-07T11:33:26 < PaulFertser> It's based on real facts but adds weird speculations and probably manipulations.
2020-07-07T11:33:41 < Cracki> I suspected as much. didn't think russia was at that point.
2020-07-07T11:34:50 < PaulFertser> It's probably a clever manipulation. Because it does have relation to the actual changes included in the new constitution.
2020-07-07T11:36:53 < PaulFertser> But even the very first statement is kind of odd. There's a special legal term "constitutional law", it's defined by the constitution and has special, more strict rules on passing. But the changes to the constitution didn't include any requirement to ban gay marriage by a "constitutional law".
2020-07-07T11:38:35 < PaulFertser> In fact, changes to the constitution declared mariage to be non-gay, that's true. But no new constitutional laws are supposed to be created based on that. And it's also a terminology question, it's like the new constitution defines a word meaning. It doesn't strictly mean that there can not be some other kind of partnership.
2020-07-07T11:40:51 < qyx> PaulFertser: I would imagine because of sound levels
2020-07-07T11:41:02 < PaulFertser> The next point: it's true they included "god" in constitution. But they do not clarify what god exactly. And the mention has no clear legal consequencies anyway.

2020-07-07T12:08:09 < Cracki> but it still says the amendments were enacted after a 78% vs 22% outcome

2020-07-07T12:14:25 < PaulFertser> Most of the amendments are plain meaningless in the legal sense. Some amendments make the constitution self-contradict now.

2020-07-07T12:20:18 < Cracki> because most people are morons and love to see one of their own in power
2020-07-07T12:20:38 < Cracki> people should be redistributed (*hammer and sickle*) to nations according to IQ
2020-07-07T12:20:58 < PaulFertser> To IQ measured on global scale?
2020-07-07T12:21:17 < PaulFertser> And how often one is supposed to remeasure it and get relocated?
2020-07-07T12:21:41 < Cracki> our corona measures prescribe various measures such as face mask, berlin wall of acrylic, two arms' length distance, or signing the guest book with your full name and address
2020-07-07T12:21:51 < Cracki> the result of the confusion: people are scared to make a wrong move and instead implement ALL the measures at once
2020-07-07T12:22:47 < Cracki> your questions show that you see the humor in my statement
2020-07-07T12:24:25 < PaulFertser> So far democracy seems to be still the "suck less" solution of choice.

2020-07-07T12:28:12 < Cracki> which is a pretty good assumption.

2020-07-07T13:17:19 < jadew> Cracki, I'm at episode 10 and I haven't noticed any propaganda
2020-07-07T13:17:30 < jadew> none
2020-07-07T13:17:43 < Cracki> I am surprised. checking.
2020-07-07T13:18:24 < jadew> and it really gets brilliant around this part
2020-07-07T13:20:46 < Cracki> 91% audience score on rottentomatoes. I guess that's a good sign.
2020-07-07T13:20:58 < Cracki> would be even better if the critics panned it
2020-07-07T13:21:01 < jadew> I didn't check that, I just decided to see it
2020-07-07T13:22:22 < Cracki> good idea. some of my favorite shows (scifi) got no love from critics and aren't broadly popular either.
2020-07-07T13:23:19 < jadew> what score did it get from the critics?
2020-07-07T13:26:44 < jadew> well, 89% is pretty good too

2020-07-07T13:31:31 < Cracki> I can dis-recommend sausage party. it's disgusting.
2020-07-07T13:32:27 < Cracki> ad astra... was an experience. "high brow" stuff.
2020-07-07T13:33:33 < Cracki> I don't see the "critique of toxic masculinity" in it. confined spaces make everyone go crazy.
2020-07-07T13:35:41 < jadew> I enjoyed the witch
2020-07-07T13:35:50 < jadew> there's nudity at the end
2020-07-07T13:35:59 < Cracki> hehehehe
2020-07-07T13:37:29 < jadew> I don't remember ad astra
2020-07-07T13:37:43 < Cracki> then you probably didn't see it :P
2020-07-07T13:37:54 < jadew> yeah, it's possible
2020-07-07T13:37:57 < Cracki> it begins with brad pitt on a kind of space elevator or very tall antenna
2020-07-07T13:38:12 < Cracki> suddenly things explode and everyone bails with parachutes
2020-07-07T13:38:17 < jadew> I'll check it out
2020-07-07T13:38:27 < Cracki> it's got shoutouts to 2001 and whatnot
2020-07-07T13:38:49 < jadew> lol @ the sausage party picture
2020-07-07T13:39:00 < Cracki> not a blockbuster, not action
2020-07-07T13:39:09 < Cracki> sausage party is pure depravity
2020-07-07T13:39:17 < Cracki> a testament to the people who made it
2020-07-07T13:39:44 < Cracki> not even tasteful depravity. tasteless. disgusting. rotten. sleazy.
2020-07-07T13:40:01 < jadew> got it
2020-07-07T13:40:27 < Cracki> oh, "snowpiercer" got 94% critics rating. I wonder how. utterly ridiculous premise and "science fiction"
2020-07-07T13:40:58 < effractur> it is really well shot
2020-07-07T13:41:08 < Cracki> a lot of these fails are books that did well for some reason, but translation to the screen misses the important part.
2020-07-07T13:41:42 < jadew> I liked snowpiercer
2020-07-07T13:41:45 < Cracki> "Someone was high when they wrote Happy Feet. It's the only logical explanation."
2020-07-07T13:41:55 < Cracki> what's not to love about animated baby penguins
2020-07-07T13:41:58 < jadew> absurd idea, but interesting concept
2020-07-07T13:43:13 < Steffanx> Unfounded. Indeed mr Cracki ;)

2020-07-07T14:20:58 < jadew> don't know, I'm on the first one still
2020-07-07T14:21:21 < jadew> glad to hear it doesn't disappoint later on

2020-07-07T14:23:07 < karlp> I mean, they do, but also don't....

2020-07-07T18:17:43 < specing> what if I wanted a BIG arm board

2020-07-07T18:18:44 < specing> > currently LPDDR4 4GB cost EUR 35, LPDDR4 8GB cost EUR 50, LPDDR4 16GB cost EUR 180.
2020-07-07T18:18:53 < specing> 2*50 = 100, wtf does 16GB cost 180
2020-07-07T18:19:10 < specing> $200 board with no sodimms
2020-07-07T18:20:22 < Cracki> maybe "ask" for a "laptop mainboard". cpu soldered on, ram (used to be) sodimm

2020-07-07T20:37:33 < zyp> just not sure exactly what I'd use it for
2020-07-07T20:37:44 < dongs> this shit is a settopbox/generic assdroid box with a bunch of modules
2020-07-07T20:37:49 < dongs> one of the modules is DVB-T transmitter
2020-07-07T20:37:53 < dongs> HDMI in-> DVB out
2020-07-07T20:38:01 < dongs> other module is some LTE shit etc
2020-07-07T20:38:38 < zyp> since the thing got both cortex-m and pcie, I could effectively run a cortex-m with memory mapped custom peripherals in a fpga hooked to pcie
2020-07-07T20:38:40 < sync> the fuck
2020-07-07T20:38:42 < dongs> also what the fuck is that forum, lol some fucking free (as in aids) mobile phone?
2020-07-07T20:38:48 < zyp> just not sure what problem that solves :p
2020-07-07T20:38:54 < sync> why would somebody build a hdmi to dvbt converter?
2020-07-07T20:39:03 < dongs> sync, to transmit stuff to TVs
2020-07-07T20:39:08 < dongs> hotel info channel and shit like that
2020-07-07T20:39:41 < dongs> you can play some crap on a desktop/assddroidbox to generate GUI and turn it into some random channel and send it over coax to all tvs in the building
2020-07-07T20:40:29 < sync> that's dvbc tho?
2020-07-07T20:40:43 < sync> but yeah I guess that is a valid usecase
2020-07-07T20:40:51 < dongs> -T, -C, its delivered same way anyway
2020-07-07T20:40:55 < dongs> over coax plugged into the shit
2020-07-07T20:41:01 < zyp> what's the difference between -t and -c once it's in a cable?
2020-07-07T20:41:02 < dongs> the chip can do japtv, dvb-t, t2, and c
2020-07-07T20:41:15 < dongs> zyp, C has qam256 or someshit
2020-07-07T20:41:17 < dongs> otherwise none
2020-07-07T20:41:20 < sync> oh, that's cool
2020-07-07T20:41:21 < dongs> T is qam64 max
2020-07-07T20:41:31 < zyp> ah, right
2020-07-07T20:41:52 < zyp> less noise in a cable so higher modulations are feasible
2020-07-07T20:41:56 < dongs> yeah
2020-07-07T20:42:16 < zyp> but still, the distinction seems a bit pointless
2020-07-07T20:42:30 < dongs> on physical layer i dont think theres much difference other than modulations
2020-07-07T20:42:45 < dongs> in TS layer there's some extra descriptors and shit in -C for cable stuff
2020-07-07T20:46:51 < dongs> time to zzz, fuck this chink debugging

2020-07-07T23:51:04 < bitmask> I really dont know what to do with this 7" touchscreen, what was I thinking, no printer needs a 7" screen
2020-07-07T23:51:59 < Ultrasauce> if you put the slicer or host on that it'd be useful
2020-07-07T23:52:00 < qyx> a big pause button in the middle?
2020-07-07T23:58:24 < bitmask> heh
2020-07-07T23:58:38 < bitmask> slicer on it would make sense but I wouldn't want to do that
2020-07-07T23:59:26 < bitmask> doubt I could do anything anyway, its a panelDue clone built in
--- Day changed Wed Jul 08 2020
2020-07-08T00:01:27 < bitmask> I did get a PID temp controller with SSR and a 350W or something heating plate, I want to make some kinda press to apply dry film to copper clad
2020-07-08T00:04:36 < Ultrasauce> i believe a laminator is the right tool for that job

2020-07-08T00:06:12 < bitmask> I took a guess and decided temperature was more important than pressure, cant really set a temperature with a laminator

2020-07-08T00:38:37 < Steffanx> What have I done to you?
2020-07-08T00:41:13 < Steffanx> upgrdman: used a laminator i recall, bitmask 
2020-07-08T00:41:22 < Steffanx> Ages ago
2020-07-08T00:41:33 < Steffanx> When he was still into the ghetto 
2020-07-08T00:41:46 < bitmask> i know it can work, i just didnt feel like buying one
2020-07-08T00:41:46 < upgrdman> ?
2020-07-08T00:41:50 < upgrdman> what's going on?
2020-07-08T00:42:36 < upgrdman> oh, soldermask
2020-07-08T00:42:50 < Steffanx> Bitmask.
2020-07-08T00:42:51 < upgrdman> ya, a simple laminator. set to hot, and run it through 2 or 3 times.
2020-07-08T00:43:26 < bitmask> meh, oh well, I listened to the wrong person
2020-07-08T00:43:30 < bitmask> this should still work fine
2020-07-08T00:43:53 < upgrdman> i never got it perfected, but i got decent results: http://farrellf.com/projects/hardware/2014-01-17_DIY_PCBs_with_Solder_Mask/
2020-07-08T00:45:08 < bitmask> nice
2020-07-08T00:45:30 < bitmask> im trying liquid soldermask, the film im using is etch resist
2020-07-08T00:47:20 < upgrdman> oh, ok
2020-07-08T00:47:44 < upgrdman> i also tried liquid soldermask, could not get consistent thickness. let us know if you have success :)
2020-07-08T00:48:23 < upgrdman> these days i don't DIY PCBs anymore tho. china is cheap and i have lots of other things to work on while i wait for delivery.
2020-07-08T00:49:16 < zyp> also let us know if you fuck up and put a magnet through your screen again or something :)
2020-07-08T00:49:20 < bitmask> I found a thingiverse project for a little 2" disc sander that used a hard drive motor, its not great because it has so little torque but is useful for quick light sanding, I did make a little enclosure though and attached a pcb to it and dripped some soldermask on it and the results werent that bad
2020-07-08T00:49:34 < bitmask> zyp haha fuck you
2020-07-08T00:49:57 < zyp> :D
2020-07-08T00:50:37 < Steffanx> Lol
2020-07-08T00:50:59 < Steffanx> You should not tell about your failures here bitmask. ##stm32 does not forget
2020-07-08T00:51:13 < bitmask> meh I can laugh at myself
2020-07-08T00:51:28 < qyx> what did you..?
2020-07-08T00:51:45 < qyx> I didn't hear that story
2020-07-08T00:51:52 < kakimir> Steffanx: you are least to expect of anything suspious
2020-07-08T00:51:56 < kakimir> so it makes it a joke
2020-07-08T00:52:10 < Steffanx> Did you get it fixed in the end bitmask? I didnt hear about the end result bitmask
2020-07-08T00:52:13 < Ultrasauce> known waffel bootlegger
2020-07-08T00:52:16 < Steffanx> -mask
2020-07-08T00:53:08 < kakimir> or does it?
2020-07-08T00:53:17 < bitmask> qyx: I was making a magnetic stirrer and went to test it stupidly, I didnt glue the magnets on and it jumped to full speed and the magnet went flying, right into my screen
2020-07-08T00:53:29 < bitmask> Steffanx yea I got a new screen for it
2020-07-08T00:53:51 < qyx> lol
2020-07-08T00:54:20 < Ultrasauce> that reminds me of the first time i tried to measure the thrust of a brushless motor + prop
2020-07-08T00:54:26 < Ultrasauce> it did not go well
2020-07-08T00:55:01 < bitmask> it came so close to missing the screen, it hit like 15mm from the edge
2020-07-08T00:55:54 < Steffanx> At least i put some box over my spinning toy (an 3d printed air raid siren) before i turned it on...
2020-07-08T00:56:06 < Steffanx> And it was still scary
2020-07-08T00:56:12 < Steffanx> And looooud 
2020-07-08T00:57:49 < Steffanx> Turned it on once and never again
2020-07-08T00:58:14 < bitmask> motor controlled or hand?
2020-07-08T01:01:17 < Steffanx> Motor
2020-07-08T01:04:16 < bitmask> https://i.imgur.com/qRF7dDs.png
2020-07-08T01:04:36 < bitmask> "should" work
2020-07-08T01:05:47 < bitmask> only variable is pressure, not sure if its worth printing a 'press' for it to get repeatability
2020-07-08T01:10:09 < Ultrasauce> making it bond everywhere without bubbles strikes me as a losing battle with a planar press
2020-07-08T01:11:33 < bitmask> a roller would be a good option
2020-07-08T01:11:50 < bitmask> keeps the whole board at temp and I can apply pressure with that
2020-07-08T01:12:17 < Ultrasauce> yeah, though you'll get localized cooling where you apply pressure
2020-07-08T01:12:18 < bitmask> I dont think bubbles are really an issue though
2020-07-08T01:12:22 < Ultrasauce> which is kind of the opposite of what you need
2020-07-08T01:12:26 < bitmask> I dont think its that sensitive
2020-07-08T01:12:59 < bitmask> I can keep the board heated to the upper limit and any cooling would still be in range
2020-07-08T01:13:23 < Ultrasauce> makes sense
2020-07-08T01:14:04 < bitmask> I mean I got fairly decent results by using a hot air gun for a couple minutes and then pressing down on it with my 3d printer heat bed glass that was brought up to temp (around 80-90c)

2020-07-08T07:31:42 < upgrdman> sadly, you have to compile Mesa from git to get support for geometry shaders :(

2020-07-08T07:38:21 < Cracki> https://www.raspberrypi.org/blog/thermal-testing-raspberry-pi-4/
2020-07-08T07:39:37 < upgrdman> ya, at idle its "ok" but under load, fuck... it'll burn you if you touch it for >1s
2020-07-08T07:41:15 < upgrdman> but hey, it'll do 3d graphics at 4k... so i shoudn't bitch too much
2020-07-08T07:42:05 < Cracki> seven wats isn't that much compared to other things (even LED light bulbs, desktop processors, ...) but concentrated...
2020-07-08T07:43:16 < upgrdman> kinda douchey that they say proudly report that the gpu supports opengl es 3.2, but very quietly admit that the drivers only support 3.1 :(
2020-07-08T07:43:53 < Cracki> the "stand it vertical" maneuver even lets you get away without a fan
2020-07-08T07:44:00 < Cracki> lol
2020-07-08T07:44:06 < Cracki> any plans for the drivers to reach 3.2?
2020-07-08T07:44:15 < upgrdman> supposedly it's in the works
2020-07-08T07:44:53 < upgrdman> office mesa build doesn't even support geometry shaders. git version does (via extension) but it's still es 3.1
2020-07-08T07:44:58 < upgrdman> official*
2020-07-08T07:47:03 < upgrdman> side note, for any opengl devs out there: if you use regular old antialiasing on nvidia gpus, it's SLOW AS SHIT. like gtx1080 is SLOWER than intel gpu on 25W ultraportable laptop. but if you instead use MSAA, nvidia is super fast like it should be.
2020-07-08T07:48:05 < upgrdman> with my gtx1080, if i use MSAA my gpu frame time is 14ms, if i use regular antialiasing my gpu frame time is 190ms
2020-07-08T07:48:21 < Cracki> lol
2020-07-08T07:48:33 < Cracki> what are they doing, supersampling the whole picture?
2020-07-08T07:48:44 < upgrdman> inorite, and the MSAA even looks better (less aliasing)
2020-07-08T07:48:53 < upgrdman> guessing so, not sure
2020-07-08T07:49:20 < Cracki> yeah, seems to be just Full Scene AA
2020-07-08T07:49:35 < upgrdman> heh, lol
2020-07-08T07:50:13 < Cracki> wikipedia says msaa only supersamples depth and stencil values, fragment only once
2020-07-08T07:50:31 < upgrdman> ya i knew that part
2020-07-08T07:54:48 < Cracki> i actually took a class called "computer graphics" that should have contained this stuff... but somehow I don't remember it from the class. I knew the reasons and operation of a z-buffer before that but I don't remember mention of the stencil part at all
2020-07-08T07:57:53 < upgrdman> if your uni was anything like mine, most of the profs weren't good enough to survive in the real world, so they couldn't actually explain much beyond what their teacher's guides spoonfed them.
2020-07-08T07:58:39 < upgrdman> my senior year i had a class on "user interface design" where we designed no user interfaces. seriously :)
2020-07-08T08:01:51 < Cracki> our prof who does computer graphics is actually quite good but half the lecture is held by a grad student. either way his slides don't change much over the years and it's full of stuff already so shadow volumes, like everything else, get very little time
2020-07-08T08:02:49 < Cracki> our user interface design class is... very interactive. I think in one of the earlier sessions they focus on mockups, so only paper cutouts, or maybe the digital equivalent of that.

2020-07-08T08:07:51 < Cracki> the slides are rarely good enough to replace a script, but often used as such... ¯\_(ツ)_/¯
2020-07-08T08:10:26 < upgrdman> the few good teachers i had were the type that would walk into class with some notes (for their own use) and a few dry-erase markers. that's when you know that the prof was knowledgeable. if the prof walked in and opened up a PPT, he/she was usually crap
2020-07-08T08:13:21 < upgrdman> surprisingly, one of the smartest CS profs i had didn't even know how to code much at all. he taught the algorithms class, and was super smart and able to explain things... and he didn't understand the basics of using an IDE or even a text editor.

2020-07-08T13:50:10 < Cracki> do they have dns filtering or other nannying

2020-07-08T14:15:37 < Cracki> btw, how much does a good ground harness cost?
2020-07-08T14:18:53 < Cracki> lol "evening speed"
2020-07-08T14:19:16 < Cracki> I guess they oversubscribe like mad

2020-07-08T14:21:48 < dongs> guys what would be faster, 1MHz I2C or 240k baud UART where 1 actual data bit = 8 bits over uart
2020-07-08T14:21:58 < dongs> it seems i2c would be faster, no?
2020-07-08T14:22:06 < Cracki> wat, 1 bit = 8 bit??
2020-07-08T14:22:10 < Cracki> you must mean byte
2020-07-08T14:22:15 < dongs> to send 8 bits over UART would mean sending 8 bytes
2020-07-08T14:22:23 < dongs> its one of those protocols thats like
2020-07-08T14:22:32 < dongs> 0xAA = 0 0x88 = 1 or whatever
2020-07-08T14:22:44 < Cracki> raw symbol rate, 1 Mbaud > 240 kbaud
2020-07-08T14:22:50 < dongs> so to send 0b111000 you'd send AA AA AA AA 88 88 88 88
2020-07-08T14:23:00 < Cracki> but since i2c has addresses, you'll have to figure usable bandwidth
2020-07-08T14:23:08 < Cracki> uhhhh
2020-07-08T14:23:16 < Cracki> why can't you send 8 bits as one byte?
2020-07-08T14:23:30 < dongs> because thats how it works
2020-07-08T14:23:40 < Cracki> what do the other 7 bits do
2020-07-08T14:24:08 < dongs> what do you mean
2020-07-08T14:24:23 < Cracki> 240kbaud and 1 payload bit per word (8N1 = 10 symbols) -> 24 kbit/s
2020-07-08T14:24:29 < dongs> < dongs> so to send 0b111000 you'd send AA AA AA AA 88 88 88 88
2020-07-08T14:24:47 < Cracki> 1 Mbaud and whatever overhead, but 1 bit is 1 bit, maybe, at worst, 500 kbit/s
2020-07-08T14:24:55 < dongs> so i2c is much faster
2020-07-08T14:25:04 < dongs> in this case
2020-07-08T14:25:04 < Cracki> sure but why do you have to encode bits like that on the uart?
2020-07-08T14:25:12 < dongs> thats just how they want it

2020-07-08T14:43:30 < Jak_o_Shadows> Cracki, nah, the idea was for everybody to have a consistent level. Have the inner city subsidise the regional areas, and allow remote work to actually happen. Have a base good internet speed, and it makes things so much easier
2020-07-08T14:44:08 < Cracki> straya is a big place
2020-07-08T14:44:42 < Cracki> cheapest way to connect would be wireless. i guess they're doing that.
2020-07-08T14:45:20 < Cracki> still not thrilling to see the prices and seeming rarity of >100 Mbit/s connections
2020-07-08T14:46:22 < Cracki> at least I saw a 100/20 ratio. around here, if you pick the cheapest provider, you get 120/5, which is the bare minimum for TCP acks
2020-07-08T14:47:47 < Cracki> yes yes, tcp doesn't need to ack every packet individually
2020-07-08T14:48:25 < zyp> dongs, 1 MHz i2c would be faster than 240kbaud UART even without retarded encoding schemes
2020-07-08T14:55:46 < Jak_o_Shadows> ehh, like, long distances are wireless - but more expensive. The point was to subsidise them so everybody was on an even footing
2020-07-08T14:56:13 < Jak_o_Shadows> and like, big place, and nothing like high density cities, but the population is located mostly in the cities
2020-07-08T14:56:36 < Cracki> around here they still ride on copper a lot
2020-07-08T14:57:01 < englishman> this FT60x library uses the term "drain"
2020-07-08T14:57:07 < Cracki> the fiber is growing tho. my 100/40 is maybe 100 meters of copper. before that we had 50/10 on ~520m of copper
2020-07-08T14:57:21 < englishman> to perform the function of clearing buffers, resetting and preparing to transfer shit
2020-07-08T14:57:28 < englishman> anyone seen that before
2020-07-08T14:57:35 < karlp> yeah? I use it myself?
2020-07-08T14:57:45 < englishman> oh yeah? first time ive seen it

2020-07-08T14:58:20 < englishman> non-rhotic language thing?
2020-07-08T14:58:38 < karlp> non-rhotic?
2020-07-08T14:59:27 < englishman> is there a specific set of dialect-speakers that would use "drain" over "clear"
2020-07-08T15:00:28 < karlp> clear implies "clear" (delete, throw away) drain implies ... drian it out, 
2020-07-08T15:00:36 < karlp> ie, wait for it to finish, vs hard stop now...
2020-07-08T15:00:53 < englishman> ahh i see
2020-07-08T15:01:46 < zyp> yeah, that's what I've seen too
2020-07-08T15:03:00 < zyp> drain = stop accepting new stuff and finish the remaining stuff that's already accepted

2020-07-08T15:25:29 < Cracki> fifo is fairness and fairness is a white supremacist concept. if you don't give your spot in the line for those with more retard points, you're evil

2020-07-08T15:28:28 < mawk> "first..." conveys the idea that there is some kind of ranking among people

2020-07-08T15:31:52 < strata> zyp: 2 out of 12 are defective. i automated install and operations of them. so they all have identical configurations both hardware and software-wise.
2020-07-08T15:32:15 < strata> and two of them just randomly flake out / kernel panic within minutes after you put any kind of stress on them
2020-07-08T15:32:51 < strata> i've been able to consistently cause them to flake out over the past two weeks now. and it's always just those two - with all others being smooth as a feather.

2020-07-08T15:35:15 < strata> so now i'm thinking i'll replace 3 of them with another SoC maybe odroid
2020-07-08T15:35:43 < strata> that way i have 1 spare rock64 to use as replacement for any of the remaining that decide to flake out too

2020-07-08T19:26:47 < Steffanx> Very likely its going to be all ff's nn7
2020-07-08T19:26:57 < Steffanx> 0xff
2020-07-08T19:27:00 < nn7> hmm.. but not guaranteed?
2020-07-08T19:28:53 < Steffanx> Is there anything guaranteed in life?
2020-07-08T19:29:37 < Steffanx> But.. yeah its going to be 0xff is everything went right
2020-07-08T19:29:43 < nn7> k thanks :)
2020-07-08T19:31:44 < nn7> if I used "data = *(__IO uint32_t*) address" what size is "data" and why?
2020-07-08T19:31:51 < Cracki> uint32_t
2020-07-08T19:32:17 < Cracki> unless __IO is #defined to be dragons
2020-07-08T19:32:27 < Cracki> probably just volatile

2020-07-08T19:33:01 < Steffanx> Is this your homework nn7 ;)
2020-07-08T19:33:20 < nn7> Ha! Not quite.
2020-07-08T19:34:03 < nn7> I cobbled together some routines to read and write flash for saving configuration and I'm trying to generalize the code a bit so it can be shared across multiple projects.
2020-07-08T19:34:16 < Cracki> optical tracking eh, that's fun
2020-07-08T19:34:52 < nn7> I don't understand why "data" has to be 32 bit.
2020-07-08T19:35:34 < Cracki> why not
2020-07-08T19:35:52 < Cracki> you wanna read single bytes? the flash probably doesn't support reading that narrowly
2020-07-08T19:36:05 < Cracki> some flash even needs 64 bit wide access
2020-07-08T19:36:24 < Cracki> mine luckily supports 16 bit. cuts down on waste.
2020-07-08T19:36:29 < nn7> I'm fine with that. I just want to understand what about that code tells me that what I'm going to get back is 32 bits.
2020-07-08T19:36:39 < Cracki> address is whatever
2020-07-08T19:36:44 < nn7> or 64 bits or 9 bits
2020-07-08T19:36:48 < Cracki> uint32_t* means now you have a pointer to uint32_t
2020-07-08T19:37:14 < Cracki> *... means you get one type width of data at that address
2020-07-08T19:37:16 < nn7> ahh.. uint32_t* doesn't say anything about the size of "address"

2020-07-08T19:37:29 < Cracki> pointers are usually word size, i.e. 32 bit on a 32 bit arch
2020-07-08T19:37:39 < bitmask> https://i.imgur.com/RLPkXHp.png
2020-07-08T19:37:44 < Cracki> so the pointer itself is one size, and what it points to is another
2020-07-08T19:37:53 < Cracki> let's say struct foo {double x; double y;}
2020-07-08T19:37:54 < nn7> so "address" can be any size, but but uint32_t* means that it's pointing to a 32-bit chunk
2020-07-08T19:38:19 < Cracki> (foo*)0x1234 is a pointer (word size) to a 128 bit structure
2020-07-08T19:38:24 < nn7> bitmask, looks similar to a prusa
2020-07-08T19:38:47 < bitmask> yea basically a clone

2020-07-08T20:20:24 < jpa-> qyx: not much use for cordic as the trigonometric based constants are easy enough to precalculate for the needed FFT sizes; fmac possibly useful
2020-07-08T20:23:56 < englishman> the fmac demo includes iir/fir code and generators not sure if it'll be useful for fft
2020-07-08T20:24:38 < englishman> oh, there is an fft demo 
2020-07-08T20:24:41 < englishman> there you go
2020-07-08T20:25:01 < jpa-> got a link?
2020-07-08T20:25:10 < englishman> on phone I just googled it
2020-07-08T20:25:53 < jpa-> you mean x-cube-dspdemo? that might not use fmac
2020-07-08T20:26:19 < englishman> oh you're right it's f4
2020-07-08T20:26:59 < englishman> nope, just fmac filters
2020-07-08T20:27:20 < jpa-> looking at the refman, FMAC could probably be used to implement the first stage of real-input FFT, which generally consists of 4 FIR filters https://github.com/PetteriAimonen/QuadPawn/blob/master/Runtime/fix16_fft.c#L36

2020-07-08T20:28:18 < jpa-> but it has to be a quite long FFT to be worth it, as it won't be faster than CPU doing it and you have to have use for the short time freed while it runs on background
2020-07-08T20:28:45 < jpa-> i guess you could run the further stages of the FFT in parallel then, if things are timed carefully
2020-07-08T20:32:33 < bitmask> jadew yea
2020-07-08T20:32:45 < jadew> what metal were you plating with?
2020-07-08T20:32:53 < bitmask> copper
2020-07-08T20:33:12 < jadew> I see, I want to plate copper with nickel :P
2020-07-08T20:33:30 < jadew> was wondering if you have any tips
2020-07-08T20:33:34 < bitmask> yea I was considering going that route eventually, but I didnt really have anything to plate :P
2020-07-08T20:33:43 < jadew> heh
2020-07-08T20:34:28 < jadew> did you make the solution yourself? with vinegar and salt?
2020-07-08T20:34:30 < bitmask> only tips I can give is make sure everything is extremely clean and smooth and do a lot of testing to find the right parameters for your need
2020-07-08T20:34:48 < jadew> ah ha, so it can fail, eh?
2020-07-08T20:35:22 < bitmask> yes but not vinegar and salt
2020-07-08T20:36:13 < bitmask> sulfuric acid and copper sulfate with some other additions, copper brightener from midas is the best improvement, I also added propylene glycol or whatever miralax is
2020-07-08T20:36:41 < bitmask> and a couple drops of hydrochloric acid for chloride ions
2020-07-08T20:36:56 < jadew> sounds complicated
2020-07-08T20:37:07 < jadew> did it look bad without the brightener?
2020-07-08T20:37:16 < bitmask> i mean you can just buy the solution and then you just add brightener as you go since it is used up in the process
2020-07-08T20:37:44 < bitmask> yea it looks bad unless its flat and you can buff it up
2020-07-08T20:37:54 < bitmask> with the brightner it comes out nice and shiny
2020-07-08T20:38:01 < jadew> I see
2020-07-08T20:38:12 < bitmask> you can also electropolish which I wanted to look into
2020-07-08T20:38:16 < bitmask> using phosphoric acid
2020-07-08T20:38:51 < bitmask> then you grow the layer and it will look ugly but you reverse plate it in the new solution and it polishes it to a shine just like the brightener apparently
2020-07-08T20:38:58 < jadew> how does that work? wouldn't it "polish" inside scratches too?
2020-07-08T20:38:59 < bitmask> and then thats cheaper in the long run
2020-07-08T20:39:16 < jadew> ah, I see
2020-07-08T20:39:28 < jadew> youtube videos make it seem like nickel plating is not that complex
2020-07-08T20:39:39 < jadew> and seems to yield good results easily
2020-07-08T20:39:56 < bitmask> i mean if you already have a good copper layer then its not a problem
2020-07-08T20:40:09 < bitmask> its all dependent on the layer you are plating onto
2020-07-08T20:40:18 < jadew> I'm plating on brass
2020-07-08T20:40:24 < bitmask> same thing
2020-07-08T20:40:52 < bitmask> if the brass is in good condition and polished and shiny then your plating will be too
2020-07-08T20:41:44 < bitmask> plating onto metal is so much easier
2020-07-08T20:42:10 < bitmask> as long as your surface is really clean
2020-07-08T20:42:55 < bitmask> anything undesired will either cause the plating to flake off in that area or the blemish will just bleed through and be visible
2020-07-08T20:44:54 < jadew> well, it's how it came out of the CNC
2020-07-08T20:45:07 < jadew> I don't intend to polish it further, just clean it and plate it
2020-07-08T20:45:28 < jadew> I don't mind the CNC marks
2020-07-08T20:45:31 < bitmask> that should be fine
2020-07-08T20:46:05 < bitmask> cnc'ing copper? 
2020-07-08T20:46:18 < jadew> brass
2020-07-08T20:46:21 < jadew> but not me
2020-07-08T20:46:25 < bitmask> oh right brass
2020-07-08T20:46:50 < jadew> I can almost live with the tarnish
2020-07-08T20:48:01 < jadew> but I figured a nice nickel plating would look much better
2020-07-08T20:48:05 < jadew> considered gold too
2020-07-08T20:48:29 < bitmask> yea I wanted to do gold :P
2020-07-08T20:51:16 < jadew> I actually have some gold plated connectors that I might nickel plate :P
2020-07-08T20:51:29 < bitmask> haha why
2020-07-08T20:51:52 < jadew> I wanted them to be nickel plated to begin with (so they match the color of the enclosure), but forgot to mention that when I ordered them
2020-07-08T20:51:59 < bitmask> ahh
2020-07-08T20:52:10 < jadew> (they were custom made, so I could ask anything)
2020-07-08T20:52:35 < bitmask> I wonder if you can extract the gold plating from scrap easily enough to use to plate what you want
2020-07-08T20:52:54 < bitmask> meh probably worth the 50-100 bucks it costs for solution
2020-07-08T20:53:25 < jadew> do you think you can get that much gold from other plated stuff?
2020-07-08T20:53:53 < jadew> I saw a 1 liter solution that was claiming to have 3g of gold in it
2020-07-08T20:54:03 < bitmask> I've seen a youtube video where he extracts from scrap, it was a lot of scrap for not a lot of gold, but you dont need a lot of gold to plate
2020-07-08T20:54:26 < jadew> that is true, yeah
2020-07-08T20:55:31 < bitmask> https://www.youtube.com/watch?v=ASQCa7mfjVo
2020-07-08T20:55:38 < bitmask> I like nileRed 
2020-07-08T20:56:40 < jadew> you can order gold plated PCBs with lots of via holes and no solder mask from china, then extract the gold from them :P
2020-07-08T20:56:51 < zyp> haha
2020-07-08T20:57:24 < zyp> unlikely to be worth it, isn't it?
2020-07-08T20:57:37 < jadew> probably not worth it, yeah
2020-07-08T20:57:50 < jadew> I guess we can calculate how much gold it would be there based on the thickness they specify
2020-07-08T20:58:05 < jadew> let's check
2020-07-08T20:58:41 < jpa-> i wonder what china uses for the fake/cheap gold on some gold plated stuff
2020-07-08T20:58:51 < zyp> «The typical thickness ranges from 0.05 – 0 23 µm (2 – 9 µ in) gold over 2.5 – 5.0 µm (100 – 200 µ in) electroless nickel.»
2020-07-08T20:59:02 < jpa-> haven't tried PCBs, but i left some "gold plated" contacts in vinegar and it dissolved, which AFAIK gold shouldn't do
2020-07-08T20:59:15 < bitmask> https://www.riogrande.com/product/midas-24k-gold-plating-solution-concentrate-cyanide-based/335082
2020-07-08T20:59:55 < jadew> so for gold it's 0.05 to 0.023 μm?
2020-07-08T21:00:01 < jadew> sorry, 0.23
2020-07-08T21:00:16 < zyp> that's what a random google hit says, yes
2020-07-08T21:00:43 < jadew> so let's say 0.14
2020-07-08T21:01:11 < bitmask> https://www.goldplating.com/collections/bath-gold/products/24k-bright-gold-solution
2020-07-08T21:01:13 < zyp> wouldn't 0.05 be a better number if you're planning to get the boards from china? :p
2020-07-08T21:01:19 < bitmask> that says it covers 800 sq inches with a thickness of 10 micron
2020-07-08T21:01:29 < jadew> zyp, haha
2020-07-08T21:03:33 < jadew> ok, so you would get 2.8 cubic mm of plating with .14 μm plating and 1 cubic mm with .1 μm plating on a 10x10 board (no vias)
2020-07-08T21:03:47 < zyp> so gold density is 19.3 g/cm3, multiply that by 0.05 um, you get .965g/m2
2020-07-08T21:04:35 < jadew> 0.054 grams with .14
2020-07-08T21:04:48 < jadew> and 0.0193 with .1
2020-07-08T21:04:56 < jadew> sorry, with .5
2020-07-08T21:04:58 < jadew> sorry, with .05
2020-07-08T21:05:08 < jadew> let's multiply that by 10
2020-07-08T21:05:23 < jadew> and we have 0.54 / 0.193
2020-07-08T21:05:49 < jadew> lol, there's proffit
2020-07-08T21:06:01 < jadew> 1 gram of gold is $58
2020-07-08T21:06:32 < jadew> 31.320
2020-07-08T21:06:41 < jadew> or 11.194
2020-07-08T21:06:47 < jadew> price of board: $18
2020-07-08T21:07:01 < jadew> there's also shipping, but you can buy more boards :P
2020-07-08T21:07:09 < bitmask> did you take carat into account?
2020-07-08T21:07:24 < jadew> you think it's not pure?
2020-07-08T21:07:36 < jadew> would it work if it wasn't?
2020-07-08T21:07:42 < jadew> (the plating process)
2020-07-08T21:07:46 < zyp> so a double sided 10x10cm board got around 0.02g of gold or $1.16 worth
2020-07-08T21:07:47 < bitmask> not sure
2020-07-08T21:08:02 < bitmask> i dont know what else is in gold to make a lower carat
2020-07-08T21:08:19 < jadew> zyp, yeah
2020-07-08T21:08:29 < jadew> that's without vias
2020-07-08T21:08:44 < zyp> jlcpcb is $82.7 for 100
2020-07-08T21:08:56 < jadew> if you can get a 2mm FR-4 and optimize the via diameter, you could get even more gold :D
2020-07-08T21:09:29 < zyp> I bet they'll tell you to fuck off as soon as they review your order :p
2020-07-08T21:09:38 < bitmask> :P
2020-07-08T21:09:42 < jadew> yeah, was thinking the same hehe
2020-07-08T21:10:55 < jadew> btw, I meant 0.05 μm of plating for the low value case, not .1 as I wrote
2020-07-08T21:11:11 < zyp> but how is it, via plating and surface finish are separate processes?
2020-07-08T21:11:36 < jadew> I assume they first deposit the copper for the vias
2020-07-08T21:11:46 < jadew> then they plate, the final board
2020-07-08T21:11:58 < zyp> before or after solder mask?
2020-07-08T21:11:58 < jadew> after soldermask I assume, no?
2020-07-08T21:12:06 < zyp> that's what I thought too
2020-07-08T21:12:20 < zyp> but vias are obviously plated through before, since they can be tented
2020-07-08T21:12:38 < jadew> yeah, I think vias are done right after drilling
2020-07-08T21:13:02 < jadew> probably even before etching, no?
2020-07-08T21:15:25 < jadew> if you're greedy, you can add castellated holes too lol
2020-07-08T21:19:01 < zyp> don't you risk etching the via if you plate it before etching?
2020-07-08T21:20:01 < jadew> hmm, good point
2020-07-08T21:20:07 < jadew> but how do they deposit the copper tho?
2020-07-08T21:25:12 < zyp> no, you're right
2020-07-08T21:25:14 < zyp> https://electronics.stackexchange.com/a/105991
2020-07-08T21:27:10 < jadew> you could ask for 2oz copper and recover that too
2020-07-08T21:32:48 < jadew> ah, copper is free by comparison
2020-07-08T21:35:19 < Cracki> uh, you want... sheets of copper...?
2020-07-08T21:35:37 < Cracki> and buying PCBs from china is cheaper than buying copper locally?
2020-07-08T21:35:46 < Cracki> I'm missing something
2020-07-08T21:35:56 < jadew> Cracki, you're missing the gold :P
2020-07-08T21:36:15 < Cracki> so buy sheets of gold locally
2020-07-08T21:36:24 < jadew> the question was weather it would be advantageous to buy gold plated PCBs and recover the gold :P
2020-07-08T21:36:48 < jadew> I figured that you could also add copper to the mix, but copper is too cheap, so you'd be losing money on that
2020-07-08T21:36:59 < Cracki> I say no. gold price is the same, they haven't discovered alchemy yet, the rest of the pcb costs too, and... eh
2020-07-08T21:37:45 < Cracki> if you have to put any effort into recovering raw materials _yourself_, it's highly likely cheaper to just buy the stuff in dissolved or whatever form is best
2020-07-08T21:38:03 < jadew> probably
2020-07-08T21:38:14 < Cracki> fun thought tho
2020-07-08T21:38:16 < jadew> unless you buy in high qty
2020-07-08T21:38:32 < jadew> 10k of this empty PCB please!
2020-07-08T21:39:18 < Cracki> you're thinking scrap?
2020-07-08T21:39:23 < jadew> yeah
2020-07-08T21:39:26 < Cracki> I think they'd sell you scrap for scrap money
2020-07-08T21:39:29 < Cracki> good point
2020-07-08T21:39:51 < Cracki> still has to be cheap enough to offset recovery...

2020-07-08T23:53:37 < mawk> lcm(a, b)² - gcd(a, b)² = 48
2020-07-08T23:56:09 < PaulFertser> Sorry mawk , I'm really not used to the puzzles like that :(
2020-07-08T23:56:29 < mawk> :(
2020-07-08T23:56:34 < mawk> it's not a puzzle
2020-07-08T23:56:42 < mawk> it's just a cool equation
2020-07-08T23:56:51 < mawk> remember than lcm(a, b)×gcd(a, b) = ab
2020-07-08T23:56:55 < mawk> then it goes all by itself
2020-07-08T23:58:09 < mawk> lcm(a, b)² - gcd(a, b)² = [lcm(a, b) - gcd(a, b)][lcm(a, b) + gcd(a, b)] = gcd(a, b)² [ lcm(a, b)/gcd(a, b) - 1 ] × [ lcm(a, b)/gcd(a, b) + 1 ]
2020-07-08T23:58:35 < mawk> lcm(a, b)/gcd(a, b) is ab/gcd(a, b)² as per what I said
2020-07-08T23:58:44 < mawk> so, (a/gcd(a, b)·(b/gcd(a, b))

2020-07-08T23:59:32 < qyx> notice the 1st pin
--- Day changed Thu Jul 09 2020
2020-07-09T00:00:18 < mawk> call a' = a/gcd(a, b) and b' = b/gcd(a, b), they are the reduced versions of a and b such that gcd(a', b') = 1; so to sum up we've got gcd(a, b)² · (a'b' - 1) · (a'b' + 1) = 48
2020-07-09T00:00:29 < mawk> I've transformed it enough PaulFertser you can finish it up

2020-07-09T00:01:39 < mawk> try to solve it
2020-07-09T00:02:10 < mawk> the goal is to find all the ways to write 48 as m²(k+1)(k-1)
2020-07-09T00:02:43 < mawk> I give you one for free: 48 = 1²·(7-1)(7+1)

2020-07-09T00:49:22 < PaulFertser> The previous work session included porting some code from new incompatible version of their mega-framework to the old one, and on the next day I had to port some other code from the old framework to new. But that wasn't the most disappointing episode of that work.
2020-07-09T00:52:53 < PaulFertser> I once spent helluva time with "gperf" trying to find a resource hog, finally pinpointed it to a place where I saw a busy waiting loop with a comment "should this probably be using a thread sleeping function?"...

2020-07-09T15:42:38 < Laurenceb> You watch those pig videos on youtube? You see the one about a drunk pig? You got this pig. He's the king of the hill, huge belly out to here. He's laying under a fence, in the middle of the farm. He's so big, he's so drunk. He doesn't want to move. Now the farmer comes, he starts messing with him. Tickling his belly, kicking him. He doesn't do
2020-07-09T15:42:38 < Laurenceb> anything. The farmer, he starts rolling him. The pig rolls down a hill. Still nothing. Till one moment, that pig gets up and oinks
2020-07-09T15:59:03 < strata> and you say "that's the US govt."
2020-07-09T16:00:25 < jadew> godaddy sucks so bad...
2020-07-09T16:00:48 < jadew> after you transfer a domain away, they offer you the discounted price again
2020-07-09T16:01:12 < jadew> "we hate to see you go"
2020-07-09T16:01:31 < strata> danica can suck my dick tho
2020-07-09T16:01:36 < strata> but i wouldn't put it in her
2020-07-09T16:01:36 < jadew> well, I'd hate it if I stayed more, so bye
2020-07-09T16:01:46 < PaulFertser> What's your opinion on namecheap?
2020-07-09T16:01:55 < jadew> PaulFertser, that's what I'm using now
2020-07-09T16:01:59 < strata> namecheap is worse
2020-07-09T16:02:03 < jadew> they're cheap
2020-07-09T16:02:12 < jadew> the website needs improving tho
2020-07-09T16:02:27 < jadew> I don't know what's with these domain registrar companies having shit websites
2020-07-09T16:02:48 < jadew> strata, it's not worse at all
2020-07-09T16:02:54 < strata> you'll see
2020-07-09T16:03:03 < jadew> everything costs me less than half what it did with godaddy
2020-07-09T16:03:09 < jadew> well, I've been using them for several years
2020-07-09T16:03:31 < PaulFertser> namecheap wasn't problematic for me since 2013.
2020-07-09T16:03:57 < strata> i used them for years too
2020-07-09T16:03:59 < jadew> the only problem I have with them is that I can't enable any type of recurrent payment thing
2020-07-09T16:04:14 < jadew> strata, why did you give up on them?
2020-07-09T16:04:14 < strata> until i tried to register a domain... can't recall what it was. but it was some odd .tld
2020-07-09T16:04:41 < strata> and they put my whole account on some kind of suspension pending a verification thing because of some weird requirementn with said .tld
2020-07-09T16:04:50 < strata> and it basically fucked all of my domains for a week
2020-07-09T16:04:57 < strata> so i had to lawyer up on them
2020-07-09T16:05:06 < strata> and got free transfers the fuck outta there
2020-07-09T16:05:21 < jadew> I haven't had any such problems with them
2020-07-09T16:05:27 < jadew> what are you using now?
2020-07-09T16:05:39 < strata> gandi
2020-07-09T16:06:42 < jadew> what's the renewal price for .com?
2020-07-09T16:06:59 < strata> lemme chek
2020-07-09T16:07:18 < jadew> $13.16 on namecheap
2020-07-09T16:07:23 < jadew> 15.16 for .net
2020-07-09T16:08:06 < strata> i have .net and .com on gandi holdon i gotta find my MFA key

2020-07-09T16:10:05 < strata> $15.50 for .com
2020-07-09T16:11:16 < strata> i'll gladly pay a little extra for not having to deal with bullshit
2020-07-09T16:11:33 < jadew> what tld did you try to get?
2020-07-09T16:11:35 < jadew> .mafia
2020-07-09T16:11:37 < jadew> ?
2020-07-09T16:12:00 < strata> is there a .mafia tld?
2020-07-09T16:12:11 < jadew> I don't know... there are so many right now
2020-07-09T16:12:17 < strata> nah it was when i tried to get my .tech
2020-07-09T16:12:22 < jadew> you can make your own tld if you have the money
2020-07-09T16:13:01 < strata> some dominican guy with my same last name is squatting on the one i reeeeallly want
2020-07-09T16:13:14 < strata> he's also a computer nerd so i'm not upset about it
2020-07-09T16:13:53 < strata> as long as it's a real person using the domain i'm happy
2020-07-09T16:14:18 < strata> those domain squatter companies are scumbags
2020-07-09T16:14:28 < jadew> yeah, I hate them too
2020-07-09T16:14:44 < jadew> and it's impossible to compete with them
2020-07-09T16:15:03 < jadew> they own thousands of registrars, for the sole purpose of registering dropped domains
2020-07-09T16:15:14 < jadew> so now you can't even wait for a domain to drop
2020-07-09T16:15:21 < jadew> because they'll buy anything
2020-07-09T16:15:43 < jadew> I had a domain name for something I developed that I decided to keep for myself in the end

2020-07-09T16:15:59 < jadew> and when I let it expire, it got bought instantly
2020-07-09T16:16:21 < strata> it didn't get bought instantly
2020-07-09T16:16:23 < strata> there's a grace period
2020-07-09T16:16:44 < jadew> yeah, when that is over they buy it milliseconds
2020-07-09T16:17:22 < strata> you have like 30 days after expiration to reclaim it for the cost of renewal - then after that there's another period where you can reclaim it for a small extra fee like $150 or something.
2020-07-09T16:17:22 < strata> after that it gets poached by the domain squatters
2020-07-09T16:17:35 < strata> they will usually hold it for like 1 year and if nobody buys it, they release it.
2020-07-09T16:17:55 < strata> i actually had a domain i bought in 2010 expire, go through that whole process... and i bought it back after like 2 years lol
2020-07-09T16:18:28 < strata> yep
2020-07-09T16:18:33 < strata> their shit is automated
2020-07-09T16:18:44 < jadew> strata, yeah, I know about the expiration process, my point is that if you want this guys domain for example, you won't get it
2020-07-09T16:18:53 < jadew> because they'll buy it first, after it gets dropped
2020-07-09T16:18:55 < strata> also the registrars will often park your shit during the grace period and make it look like it's held by a domain squatter
2020-07-09T16:19:36 < strata> you can get it tho
2020-07-09T16:20:00 < strata> if you watch the domain and it goes into expiration, wait the grace period
2020-07-09T16:20:08 < strata> and botnet the purchase
2020-07-09T16:21:59 < strata> if you succeed, it probably crashes some program the squatters use and their IT guy gets fired
2020-07-09T16:22:26 < strata> or taken out back and shot - since a lot of those companies are more like drug cartels operating in antigua or some shit
2020-07-09T16:23:23 < strata> squatting is just 1% of their biz. the rest is making content for pornhub with trafficked girls from epstein island or whatever

2020-07-09T19:37:14 < zyp> for names I can vouch for gandi
2020-07-09T19:37:23 < zyp> I like their philosophy: https://www.gandi.net/en/no-bullshit
2020-07-09T19:38:32 < englishman> is there some better place to host for like $5/year
2020-07-09T19:38:42 < englishman> I moved to them about a year ago from nfsn
2020-07-09T19:38:43 < Cracki> hmmm if you owned the daily stormer domain, would you keep it with them?
2020-07-09T19:38:51 < Cracki> y'all*
2020-07-09T19:39:27 < zyp> englishman, nah, but I wouldn't get anything less than a small vps for hosting
2020-07-09T19:39:38 < zyp> cx11 from hetzner is the cheapest decent option I know of
2020-07-09T19:39:57 < PaulFertser> Hurricane Electric hosts me for free.
2020-07-09T19:40:32 < zyp> they are like $30 a year, but for moneyed westerners like us that's nothing
2020-07-09T19:41:59 < PaulFertser> Cracki: I'm interested but I get <Message>Access denied.</Message> in XML instead of a pic.
2020-07-09T19:42:06 < englishman> I pay for shared hosting specifically to not have to maintain some lunix
2020-07-09T19:42:28 < englishman> I have this ovh VPs for chatting that's enough lunix for me
2020-07-09T19:42:36 < Cracki> odd. I guess it deleted itself after some time. that's no image sharing site. here: https://i.imgur.com/iiS8x4H.jpg

2020-07-09T19:42:49 < zyp> englishman, why don't host shit on that?
2020-07-09T19:43:09 < englishman> sounds like work, installing and maintaining all that stuff
2020-07-09T19:43:28 < zyp> all what?
2020-07-09T19:43:50 < englishman> nginx and whatever database
2020-07-09T19:44:08 < englishman> something breaks on every update
2020-07-09T19:44:22 < englishman> so like 15y ago I went to shared hosting and never looked at a console again
2020-07-09T19:44:48 < englishman> same reason I don't host my own email server and pay google for the service
2020-07-09T19:45:04 < PaulFertser> Cracki: I'd say it's nice. Unusual square headlamp. Shouldn't be too noisy. Probably you hear it loud due to reflections from the walls.
2020-07-09T19:45:36 < Cracki> it's not "loud" but it's noisier than ANYTHING out there
2020-07-09T19:45:56 < Cracki> including someone taking an angle grinder to random scrap
2020-07-09T19:46:10 < Cracki> including someone running a leaf blower and a weed whacker
2020-07-09T19:46:22 < zyp> can agree on the last point
2020-07-09T19:46:23 < zyp> but email is a shitfest and last I checked (which was arguably forever ago) there were no opensource webmail clients that'd rival gmail
2020-07-09T19:46:33 < Cracki> ^ my pain
2020-07-09T19:46:43 < zyp> web stuff is easy as fuck
2020-07-09T19:46:49 < Cracki> nobody seems to understand the point of gmail's threading
2020-07-09T19:47:08 < Cracki> they all treat individual emails as first class objects, or sperg out and show a fucking tree

2020-07-09T20:08:36 < PaulFertser> How are you not afraid to ride without ABS?
2020-07-09T20:09:06 < jadew> breaks are for pussies
2020-07-09T20:14:40 < Cracki> yeah fuck reststops just aim for the fucker who keeps riding your tail
2020-07-09T20:18:57 < englishman> never tried a bike with abs
2020-07-09T20:23:02 < Cracki> inverse bull ride
2020-07-09T20:24:43 < PaulFertser> englishman: I mean, if your break is functioning properly it's too easy to skid the front while "panic breaking", right?
2020-07-09T20:25:11 < PaulFertser> And once you skid for a split-second you fall.
2020-07-09T20:28:28 < englishman> you gotta clench the front pretty tight to lock up
2020-07-09T20:28:33 < englishman> or be turning
2020-07-09T20:29:01 < englishman> I had a rocket III that I locked up once and I was ok
2020-07-09T20:29:06 < englishman> wasn't turning tho
2020-07-09T20:29:27 < PaulFertser> Well, yes, and during an emergency you want to break hard.

2020-07-09T21:00:57 < sync> that's why you practice threshold breaking
2020-07-09T21:10:10 < Ultrasauce> bike edging
2020-07-09T21:19:45 < PaulFertser> sync: but it depends on plenty of factors, different kind of pavement, water etc. Watching accidents videos shows that most people on old bikes either severely under-brake with the front wheel, or overdo that and fall. 
2020-07-09T21:38:33 < aandrew> jpa-: thanks for that; this is on top of setting the GPIO to the correct alternative function right?
2020-07-09T21:39:34 < zyp> GPIO should default to that AF
2020-07-09T21:42:52 < aandrew> it is AF0 but I thought GPIOs were digital input by default 
2020-07-09T21:49:04 < zyp> debug GPIOs are AF by default
2020-07-09T21:49:16 < zyp> that's why you can debug the chip without setting the AF first :)
2020-07-09T21:49:48 < zyp> (and SWO doubles as JTDO if your chip is JTAG capable, so it's also a debug pin)
2020-07-09T21:52:13 < aandrew> right
2020-07-09T21:56:55 < strata> petition to change GPIO to SPIO or Special Purpose Input Output to recognize that some inputs are marginalized and should be given preference over whitey
2020-07-09T22:00:38 < aandrew> ah that's owrking better, but the JLink SWO viewer is spitting out garbage now. no way to configure protocol or baudrate, so I suspect it wants things in a specific setup
2020-07-09T22:00:42 < aandrew> which is stupid, but hey
2020-07-09T22:02:02 < zyp> shouldn't it configure SWO itself?
2020-07-09T22:04:26 < aandrew> there we go
2020-07-09T22:04:41 < aandrew> had to adjust the prescaler in jpa-'s code
2020-07-09T22:19:54 < Mangy_Dog> Its finally done! https://youtu.be/BncBolIe5Jo  :)
2020-07-09T22:21:01 < Steffanx> lol that code at ~5 minutes in.
2020-07-09T22:21:03 < Steffanx> Damn Mangy_Dog :P
2020-07-09T22:21:31 < Mangy_Dog> :p
2020-07-09T22:21:37 < Mangy_Dog> a lot of button state code
2020-07-09T22:21:56 < Steffanx> Yeah couldnt you have done some look up table and/or other array magic there?
2020-07-09T22:22:28 < Mangy_Dog> not really as it was triggered different functions
2020-07-09T22:22:32 < Mangy_Dog> i mean maybe if i put more time
2020-07-09T22:22:34 < Steffanx> And did you mean Aliexpress instead of amazon? 
2020-07-09T22:22:39 < Mangy_Dog> but i was aiming for function first
2020-07-09T22:22:42 < Steffanx> the tracking page looks like aliexpress
2020-07-09T22:22:48 < Mangy_Dog> the first is
2020-07-09T22:24:55 < Mangy_Dog> tbh yeah i mention i might one day just redor some of the code
2020-07-09T22:25:02 < Mangy_Dog> making it nicer to look at
2020-07-09T22:25:39 < Steffanx> just never look at it again :P
2020-07-09T22:25:52 < Mangy_Dog> hehe prolly
2020-07-09T22:25:58 < Steffanx> What you cant see doesnt exist right?
2020-07-09T22:26:28 < Mangy_Dog> :D
2020-07-09T22:26:36 < Mangy_Dog> but there is some personal pride
2020-07-09T22:26:52 < Mangy_Dog> i might tweak the code and clean it up more once i hage loads of free time on my hands
2020-07-09T22:27:01 < Mangy_Dog> but at this stage i HAD to finish this and get on with the stargate
2020-07-09T22:27:22 < Mangy_Dog> im going to take a couple of days off from any projects, do some cleaning up and sorting my work areas out... then get on with the gate
2020-07-09T22:28:52 < Mangy_Dog> I also wanted to have the button code huiman readable rather than just a array number
2020-07-09T22:29:03 < Mangy_Dog> sure i could define the addresses
2020-07-09T22:29:06 < Mangy_Dog> but this just seemed simpler for now
2020-07-09T22:29:36 < Mangy_Dog> btw how different is timer code for stm32?
2020-07-09T22:29:45 < Mangy_Dog> is it roughly the same as arduino?
2020-07-09T22:32:25 < Steffanx> the idea is the same..
2020-07-09T22:32:37 < zyp> haven't done timers on avr in forever, but I would guess pretty similar
2020-07-09T22:32:55 < zyp> it's just that stm32 timers have a ton of features you can get lost in
2020-07-09T22:34:54 < Steffanx> Yeah, first time i did AVR timers i was still pretty overwhelmed i remember... with all the pwm and stuff
2020-07-09T22:35:23 < zyp> aren't avr timers pretty simple by comparison?
2020-07-09T22:35:44 < Steffanx> yeah, i think so.
2020-07-09T22:35:58 < Steffanx> but the first time i did that was also the first time i ever touched a microcontroller ;)
2020-07-09T22:36:07 < Steffanx> and i didnt even know C
2020-07-09T22:36:25 < Mangy_Dog> :)
2020-07-09T22:38:14 < PaulFertser> Mangy_Dog: did I hear it right that DocScrutinizer helped you?
2020-07-09T22:38:59 < Mangy_Dog> yes
2020-07-09T22:39:27 < PaulFertser> Mangy_Dog: I enjoyed a lot communicating with him during the OpenMoko days.
2020-07-09T22:39:52 < Mangy_Dog> hes around in ##electronics if you ever wanted to talk to him :) 
2020-07-09T22:41:24 < PaulFertser> Mangy_Dog: the UI you created looks so nice, I guess I would enjoy using it. The way you integrated the screen and the power switch look awesome too. And the video itself is rather cool.
2020-07-09T22:43:00 < Mangy_Dog> thanks
2020-07-09T22:44:34 < PaulFertser> Would be really nice to see you working in a team which would allow you to show your strongest skills.
2020-07-09T22:45:11 < PaulFertser> (without being distracted by the areas you're not really interested or experienced enough in)
2020-07-09T22:45:17 < Mangy_Dog> trust me i really would love that too
2020-07-09T22:45:45 < Mangy_Dog> i need a job
2020-07-09T22:47:56 < PaulFertser> Back to the technical topics, I wasn't able to understand how exactly that dimmer helped you. Is that just that the SSR you had was zero-crossing and the dimmer is the same SSR thing but allowed you to turn it on at arbitrary point of time?
2020-07-09T22:48:34 < PaulFertser> Does it not heat up much when you're not at 100 % cycle?
2020-07-09T22:48:54 < Mangy_Dog> i didnt feel any heat that wasnt coming off the oven itself
2020-07-09T22:49:09 < Mangy_Dog> the dimmer gave me a zero signal to latch on to
2020-07-09T22:49:13 < Mangy_Dog> the ssr on its own didnt
2020-07-09T22:49:30 < Mangy_Dog> but the triac would work the same i assume
2020-07-09T22:49:35 < Mangy_Dog> in the ssr
2020-07-09T22:51:34 < PaulFertser> Another question. I do not assemble boards but few times I used hot air for repairs the resistors weren't blown off with it. What hot air gun are you using?
2020-07-09T22:54:18 < Mangy_Dog> d858
2020-07-09T22:54:25 < Mangy_Dog> the same sort of thing most people have
2020-07-09T22:54:33 < Mangy_Dog> but its more specifically because of the 0402s
2020-07-09T22:54:54 < Mangy_Dog> but yeah i find hot air guns even on a fairly low setting can blow things around a bit
2020-07-09T22:55:21 < Mangy_Dog> not always
2020-07-09T22:55:28 < Mangy_Dog> just sometimes but the smaller the things the more likely
2020-07-09T22:55:47 < PaulFertser> 0402 might end up being problematic with reflow too. Turing into tomb stones.
2020-07-09T22:57:24 < t4nk_freenode> Mangy_Dog, smoke much?
2020-07-09T22:59:35 < Mangy_Dog> do i smoke?
2020-07-09T22:59:38 < Mangy_Dog> no
2020-07-09T23:00:01 < Mangy_Dog> paul, gonna stensil the paste on on that board
2020-07-09T23:00:06 < Mangy_Dog> sooo it should be ok
2020-07-09T23:00:08 < t4nk_freenode> np, I got both of us covered :)
2020-07-09T23:00:56 < PaulFertser> Mangy_Dog: I hope so!
2020-07-09T23:01:35 < Mangy_Dog> tbh im more worried that the stensil sheets i have are too thin :p so i dont think im going to have any issue with too much paste making it tombstone
2020-07-09T23:02:35 < Mangy_Dog> gonna disapear for a bit sorting supper out
2020-07-09T23:05:50 < t4nk_freenode> look, Mangy_Dog, I watched your vid, and I am v. disappointed
2020-07-09T23:06:09 < t4nk_freenode> for the oven has NO setting for sausages, 
2020-07-09T23:06:14 < t4nk_freenode> and I mean Not at all :(
2020-07-09T23:06:57 < Steffanx> Im very disappointed in you t4nk_freenode. Such negativity.
2020-07-09T23:07:26 < t4nk_freenode> sorry for that, Sir.
2020-07-09T23:07:34 < Steffanx> lol
2020-07-09T23:07:46 < Steffanx> Hows the day in t4nkland?
2020-07-09T23:08:00 < t4nk_freenode> ah! I'm in the stm32 chan.. forgot :) wellllllllllllllll
2020-07-09T23:08:34 < t4nk_freenode> I got a f407vet6 board here, and an old monitor.. yesterday I found my old pic18f vga project
2020-07-09T23:08:44 < t4nk_freenode> and today I want to see what this stm32 can do!
2020-07-09T23:08:52 < t4nk_freenode> seems like a nice waste of time
2020-07-09T23:08:53 < Mangy_Dog> lol t4nk
2020-07-09T23:09:01 < Mangy_Dog> well
2020-07-09T23:09:16 < Mangy_Dog> i could put saussage mode into one of the custom profiles
2020-07-09T23:09:56 < Mangy_Dog> its only a case of setting time and  temp
2020-07-09T23:09:59 < t4nk_freenode> you should man, if you ever produce it for real... tell your customers there's an easter egg inside
2020-07-09T23:12:12 < t4nk_freenode> but anyway... cool project, Mangy_Dog. useful, at least a lot cheaper than a product, and fulfilling to complete I reckon
2020-07-09T23:16:55 < zyp> t4nk_freenode, if you wanna do VGA, I think the LTDC in e.g. stm32f429 can be persuaded to do that if you hook up DACs
2020-07-09T23:18:48 < zyp> https://www.youtube.com/watch?v=seekcKivPwA <- here's somebody doing it with a resistor DAC

2020-07-10T00:01:21 < jadew> yeah, it's about some singers that want to win the contest
2020-07-10T00:01:41 < Steffanx> Imdb says 6.6 so not really impressive 
2020-07-10T00:02:00 < jadew> then they are only promoting the good reviews

2020-07-10T01:24:24 < Mangy_Dog> i did :o
2020-07-10T01:24:29 < Mangy_Dog> i also really loved the ending song
2020-07-10T01:24:37 < t4nk_freenode> catphish, please stop being such a headache.
2020-07-10T01:24:39 < Mangy_Dog> brought a tear to my eye
2020-07-10T01:25:02 < Mangy_Dog> the movies not the best in the world
2020-07-10T01:25:10 < Mangy_Dog> but its fun and theres some genuingly honest LOL moments
2020-07-10T01:25:40 < kakimir> hey
2020-07-10T01:25:43 < kakimir> what movie?
2020-07-10T01:26:08 < Mangy_Dog> eurovision the story of firesaga or something
2020-07-10T01:26:29 < kakimir> hmm
2020-07-10T01:26:38 < kakimir> it was nice movie
2020-07-10T01:27:54 < Mangy_Dog> but again really loved that final song
2020-07-10T01:28:13 < Mangy_Dog> but the sing along scene. really REALLY made me cringe

2020-07-10T02:09:29 < t4nk_freenode> zyp, mmm f407vet6 has some FSMC orsth for an interface. I guess that LTDC could work without dac's too.. if you like a handful of colors ;)
2020-07-10T02:10:06 < jadew> Mangy_Dog, I liked the beginning, but couldn't get through the mid part (when they finally left and met all the other artists)
2020-07-10T02:10:35 < t4nk_freenode> nehow, I got a bunch of resistors coming, accidentally some wrong values too.. so I'll be experimenting with r2r ladders
2020-07-10T02:10:47 < jadew> Mangy_Dog, the sing along thing is when they all sing?
2020-07-10T02:10:54 < jadew> at the party?
2020-07-10T02:11:10 < jadew> because that's when I stopped watching
2020-07-10T02:15:02 < t4nk_freenode> I also got some of those esp32 thingies on order.. was hoping to experiment with audio, and more specifically if it would be possible to have  a system with two identical wireless headphones. I wonder how the latency would be, and if it would ever be usable for musical instruments in that respect
2020-07-10T02:20:43 < qyx> check WMM if ESP32 supports it, check low latency codecs (OPUS for example, or there are some with even lower latency)
2020-07-10T02:21:03 < qyx> OPUS runs ok on stm32, should run on esp32 too
2020-07-10T02:22:15 < qyx> apply some FEC, OPUS supports missed frames too

2020-07-10T02:39:03 < Laurenceb> suppp
2020-07-10T02:39:23  * Laurenceb has a canister of sunpower maxeon bare cells
2020-07-10T02:39:32 < Laurenceb> these shits are insanely good
2020-07-10T02:39:45 < Laurenceb> amorphous silicon eternally btfo'd
2020-07-10T02:42:58 < Laurenceb> they seem to have pulled off some voodo tricks with the silicon, its considerably less fragile than my modelling suggested
2020-07-10T02:45:16 < Laurenceb> I want to stick them to the surface of a sphere, modelling suggested 2m guassian radius of curvature was possible, today I managed 1.5m, then <1m with the edge crimping, fem modelling said the silicon would shatter when the perimeter of the cell starts crimping
2020-07-10T02:45:56 < Laurenceb> I think this probably outperforms amorphous silicon for guassian curvature which is mental considering its 150
2020-07-10T02:46:04 < Laurenceb> micron silicon
2020-07-10T02:46:14 < kakimir> are you workings now?
2020-07-10T02:46:34 < Laurenceb> working on stratosolar but not paid
2020-07-10T02:46:42 < kakimir> it's good
2020-07-10T02:46:59 < Laurenceb> prototpye will use these sunpower maxeon cells
2020-07-10T02:48:31 < Laurenceb> hardest part is still to come, I have to stick them to the envelope :S
2020-07-10T02:53:36 < kakimir> are they in Nottingham? 
2020-07-10T02:54:35 < Laurenceb> who? Sunpower
2020-07-10T02:54:38 < Laurenceb> they are murican

2020-07-10T18:57:34 < aandrew> anyway this is working much better now and I can confirm the guy's code sucks ass, 65% of the time it's spinning waiting for ADC to complete, and he's got an external mux reading 80 ADC channels four times each and averaging them before moving on
2020-07-10T18:58:03 < aandrew> I have a much better implementation written that I can now test and with this data I can provide before and after "here's why you want to do it this way" reporting

2020-07-10T19:13:43 < Cracki> external mux for adc, meaning "analog mux" or...?
2020-07-10T19:15:20 < aandrew> yes
2020-07-10T19:15:43 < aandrew> basically he's scanning a 16x5 matrix with a 4051 and a shift register
2020-07-10T19:15:57 < aandrew> works great until someone tries to hit to keys at the same time
2020-07-10T19:22:22 < Cracki> so what's the solution, DMA for the ADCing ofc, but control mux from a handler or do you have anything smarter than that?
2020-07-10T19:23:25 < Cracki> SPI to handle the shift register, so that could get dma'd too but juggling both...

2020-07-10T19:29:49 < aandrew> I don't even know if DMA will work as well as I hope
2020-07-10T19:29:56 < aandrew> I would like to chain a fwe DMAs to make it shine
2020-07-10T19:30:05 < aandrew> basically timer kicks off the entire thing
2020-07-10T19:30:28 < zyp> aandrew, what is this? 
2020-07-10T19:31:01 < zyp> some sort of midi keyboard or something?
2020-07-10T19:31:14 < aandrew> but set up external MUX/shiftreg/adc, and start. ADC complete DMAs four conversions, then on fourth conversion complete, triggers GPIO DMAs to shift the shift reg and after 16 of those, GPIO DMA to set the next MUX channel etc etc
2020-07-10T19:31:28 < aandrew> it'd be nice to do it all in DMA with chaining but that might be a little much
2020-07-10T19:31:29 < aandrew> zyp: yes
2020-07-10T19:32:59 < aandrew> basically 80 "variable resistors" made up of carbon silkscreened on to the PCB with a plastic sheet with more carbon pads silkscreened on to it
2020-07-10T19:33:26 < emeb> haha - I know what aandrew is doing.
2020-07-10T19:34:14 < emeb> aandrew: is the old code as bad as I was told?
2020-07-10T19:34:24 < aandrew> it's very primitive
2020-07-10T19:34:26 < Steffanx> emeb is the guy that wrote the code?
2020-07-10T19:34:28 < aandrew> but not THAT bad
2020-07-10T19:34:48 < zyp> hmm
2020-07-10T19:35:07 < emeb> Steffanx: no - this was some other dude. I had a bit of interaction with him last year and wasn't impressed.
2020-07-10T19:35:24 < zyp> managing external muxing for 80 channels sounds awful no matter what you ddo
2020-07-10T19:36:09 -!- bitmask [~bitmask@c-73-215-237-27.hsd1.nj.comcast.net] has quit [Quit: Gone to sleep...]
2020-07-10T19:36:13 < zyp> if it's set up as a shift register thing that can be advanced through the channels with just a pulse or something, maybe you could use a timer to both do that and start conversion
2020-07-10T19:37:21 < zyp> done right, you should be able to just set up an 80-conversion DMA job (or 80x4 if you want oversampling) and start the timer to kick it off
2020-07-10T19:37:44 < emeb> I love it when that works out. 
2020-07-10T19:38:05 < emeb> Do some simple timer triggers and let things run on their own.
2020-07-10T19:41:09 < aandrew> zyp: yeah the idea is a GPIO DMA which toggles the shift pin 16 times then interrupts so I can set up the shift reg for the next row, and then another GPIO DMA which does the rows with the MUX, and then the ADC DMA which reads 4 times, triggers the row DMA
2020-07-10T19:41:31 < aandrew> but really that's the holy shit 100% background, I think the ADC DMA for 4x is more than enough with short interrupts to set the next lines
2020-07-10T19:42:42 < zyp> do you really need to shift all bits through? can't you just pass in a single 1 at setup and just keep advancing the same bit?
2020-07-10T19:43:15 < zyp> that's what my old led matrix design does
2020-07-10T19:44:14 < zyp> https://bin.jvnv.net/file/AXTMf.png
2020-07-10T19:44:36 < aandrew> zyp: that's exactly what you do
2020-07-10T19:44:47 < aandrew> zyp: to start a row, you inject a '1' and toggle the clock
2020-07-10T19:44:53 < zyp> yeah
2020-07-10T19:45:10 < aandrew> then after 4x ADC, you use DMA to toggle the clock once
2020-07-10T19:45:23 < aandrew> after 16 of those, you interrupt and set the next MUX, do it all again
2020-07-10T19:46:05 < aandrew> but if you wanted to be slick, you could use 3x GPIO DMA so after the 16 column ticks, you trigger the trio to emit the next MUX address
2020-07-10T19:46:12 < zyp> if you were lucky it'd be connected to a timer capable pin so you could just do OC instead of GPIO DMA
2020-07-10T19:46:30 < zyp> much less hassle
2020-07-10T19:46:53 < aandrew> right but not. all timer channels are connected to encoder pins (there are 8 encoders)
2020-07-10T19:47:16 < zyp> fun
2020-07-10T19:47:40 < zyp> almost sounds like they should just have used a fpga

2020-07-10T19:47:55 < aandrew> in fact only 4 of htem can be used with timers, and the ohter four are software decoded which is not optimal, so they dropped all timer support and just use PIO to read and debounce and decode them
2020-07-10T19:47:59 < aandrew> yep
2020-07-10T19:48:01 < aandrew> that was my suggestion for v2
2020-07-10T19:48:30 < aandrew> a single $7 FPGA could handle all the encoders and LEDs, and with a little work, even replace the ADC
2020-07-10T19:48:41 < aandrew> but one step at a time
2020-07-10T19:49:51 < emeb> funny thing is that these ppl first approached me to do an FPGA design because they didn't think an STM32 could handle the task.
2020-07-10T19:50:13 < emeb> but then after looking at what they wanted I showed them how a single F7 could do it.
2020-07-10T19:50:24 < zyp> oh, so you're to blame :)
2020-07-10T19:50:35 < emeb> no - that was on a different product
2020-07-10T19:51:33 < emeb> and then because they like complexity, they split it up into two F7s, and then upgraded to H7s.
2020-07-10T19:51:59 < zyp> sounds like feature creep
2020-07-10T19:52:19 < aandrew> lol it's all your fault emeb

2020-07-11T00:17:37 < Steffanx> Forbidden.. isnt A-A kinda forbidden as well?
2020-07-11T00:18:01 < zyp> also, usb-c to usb-c cables will be even stiffer, as they are required to populate all four high speed pairs, vs. a usb-c to usb-a cable only needs the two that are actually connected in the A end
2020-07-11T00:18:12 < zyp> Steffanx, yes, it is
2020-07-11T00:18:42 < zyp> I'm not saying it doesn't exist, just that it's not standard compliant
2020-07-11T00:19:29 < effractur> fair enough c to c is quite stiff indeed
2020-07-11T00:19:45 < zyp> also, enjoy using an adapter that'll only work in one orientation, unless it actually contains a mux chip
2020-07-11T00:20:33 < zyp> technically an adapter could be standard compliant if it contained enough active circuitry
2020-07-11T00:20:55 < zyp> but that'd probably be expensive and fairly pointless
2020-07-11T00:21:17 < effractur> but having all 4 pairs is not required right a 2.0 cable with cconnectors is also allowed
2020-07-11T00:22:04 < zyp> yes, standard defines a 2.0 cable that's only required to have dp/dm, cc, vbus and gnd
2020-07-11T00:22:44 < zyp> and a full featured cable that's required to have everything (four ss lanes and two sbu lines in addition to what a 2.0 cable needs)

2020-07-11T02:50:36 < Laurenceb> ok anyway...
2020-07-11T02:51:14 < Laurenceb> these bare cells are somewhere between 21.5 and 24% efficient depending on the ground model I use...
2020-07-11T02:51:51 < Laurenceb> although one of my test cells is now 0% efficient...
2020-07-11T02:52:04 < Laurenceb> and has become two test cells

2020-07-11T14:53:57 < Mangy_Dog> :D
2020-07-11T14:54:04 < Mangy_Dog> or stensil is an ok spelling mistake

2020-07-11T14:54:21 < Steffanx> This is not going to work well for your qfn packages..
2020-07-11T14:57:14 < Mangy_Dog> hopefully its thin enough that the mask will make it pull
2020-07-11T14:57:20 < Mangy_Dog> or i get the wick out
2020-07-11T14:58:07 < Mangy_Dog> hhhhmmmm
2020-07-11T14:58:12 < jpa-> Mangy_Dog: how thick is the mask?
2020-07-11T14:58:26 < Mangy_Dog> .25 i think
2020-07-11T14:58:36 < jpa-> .25mm?
2020-07-11T14:59:09 < Steffanx> You might have issues with too much paste on the thermal pad..
2020-07-11T14:59:43 < jpa-> with 0.25mm thick stencil you'd probably want to reduce the apertures by quite a bit.. like 50%?
2020-07-11T15:00:14 < jpa-> and usually for thermal pad stencil holes you just have a couple of small holes instead of one huge square like that
2020-07-11T15:00:42 < Steffanx> what mr jpa- said. 
2020-07-11T15:00:44 < jpa-> you want relatively less solder on the thermal pad, to make sure the chip is not floating on it - which would make the pins not get connected
2020-07-11T15:01:17 < jpa-> if you are first timer with solder paste, i'd suggest depaneling the board and starting with the simpler ones
2020-07-11T15:01:48 < jpa-> keeping such a large panel aligned while pasting it is not easy even with steel stencils, and much harder with plastic
2020-07-11T15:01:54 < Mangy_Dog> wait no
2020-07-11T15:01:56 < Mangy_Dog> 190 microns
2020-07-11T15:02:19 < Mangy_Dog> im not a first timer with paste no
2020-07-11T15:02:53 < Mangy_Dog> but im just having a look to see if i can make the pads smaller in inkscape to help increase the chance of them not being cut out
2020-07-11T15:03:19 < jpa-> why not make them smaller when you export from your pcb software? pretty much all allow you to adjust paste clearance
2020-07-11T15:03:48 < jpa-> it's better to err on the side of too little paste, as it is very easy to add solder
2020-07-11T15:17:36 < Mangy_Dog> nodnods
2020-07-11T15:17:38 < Mangy_Dog> good point

2020-07-11T17:32:32 < Cracki> Mangy_Dog, this looks like you're going over it more than once with the scraper. clean stencil and single pass worked best for me. whenever you ease up, the stencil might lift off the pcb and by the next pass you'll squish the paste that's there
2020-07-11T17:33:32 < Cracki> the not-perfectly-perpendicular faces on the cutouts might contribute a little
2020-07-11T17:34:05 < Mangy_Dog> yeah i went over it a few times
2020-07-11T17:34:20 < Mangy_Dog> nm
2020-07-11T17:34:21 < Cracki> might still work out ok on its own
2020-07-11T17:34:29 < Mangy_Dog> its good enough for me right now i can clean up bridges regardless
2020-07-11T17:35:27 < Cracki> for such wide stencils I'd need a wide scraper and a healthy glob of paste
2020-07-11T17:36:25 < Cracki> one dude showed me to use a metal stirring rod to bunch up the paste into a tidy roll on the scraper
2020-07-11T17:38:02 < Cracki> honestly I'd have broken all those apart and done them lengthwise individually. for "mass production" maybe make a jig from some scrap pcbs where you can put the subject in place and fold over the stencil (like a book) and it's all in place
2020-07-11T17:38:39 < Cracki> big piece of work :D

2020-07-11T18:26:02 < Laurenceb> sunpower claim "up to 25%" so thats almost certainly bs as NREL say
2020-07-11T18:26:36 < kakimir> is it the best?

2020-07-11T18:27:26 < Laurenceb> I am testing bare cells, so with a plastic or glass coating the efficiency might actually improve
2020-07-11T18:27:41 < kakimir> what kind of power/kg are available?
2020-07-11T18:27:42 < Laurenceb> with antireflective glass maybe it will hit >24%

2020-07-11T18:37:35 < Laurenceb> there are amorphous silicon cells and monocrystalline
2020-07-11T18:38:31 < Laurenceb> sunpower maxeon is monocrystalline
2020-07-11T18:38:52 < Laurenceb> so 150µm silicon wafer, but it seems to be tempered 
2020-07-11T18:39:27 < Laurenceb> the one I cracked yesterday cracked from a chip in the side made by my test lead
2020-07-11T18:39:43 < Laurenceb> it seemed to behave similarly to tempered glass
2020-07-11T18:40:29 < kakimir> so are you designing an alternative design for flying solar power station?
2020-07-11T18:41:56 < Laurenceb> yes
2020-07-11T18:42:21 < Laurenceb> I'm going to try laminating these cells to plastic film
2020-07-11T18:42:32 < Laurenceb> but first I need some documented films to try
2020-07-11T18:42:40 < Laurenceb> need to email suppliers next week

2020-07-11T18:51:01 < kakimir> works on wine too
2020-07-11T18:51:16 < Steffanx> So how can it be a secret Laurenceb . Dont tell me you will patent it 
2020-07-11T18:52:34 < Laurenceb> yes
2020-07-11T18:52:43 < Laurenceb> patent is in progress

2020-07-11T20:14:34 < R2COM> zyp for some reason when scons builds files using your "build_rules" file, it throws "scons: *** An executable should have exactly one target with the suffix: .exe"
2020-07-11T20:14:46 < R2COM> not sure why though, there is no even mentioning abou anything "exe" in that file
2020-07-11T20:20:03 < Ultrasauce> sounds like that's the problem
2020-07-11T20:29:05 < tcth> Steffanx
2020-07-11T20:36:52 < R2COM> will see, it actually has to do with default ways how scons runs on win environment

2020-07-11T21:12:37 < Mangy_Dog> i just had to be special... I had to make my prop toys a bit more interactive

2020-07-12T00:21:19 < zyp> R2COM, IIRC you can fix that by telling scons you've got a gcc toolchain

2020-07-12T01:10:40 < zyp> Mangy_Dog, now you know your next project has to be building a pick and place :p
2020-07-12T01:13:40 < Mangy_Dog> i think that might be just a bit above my skill level
2020-07-12T01:13:54 < Mangy_Dog> can even diy PnP do 0402 :p

2020-07-12T01:24:10 < Mangy_Dog> its damn near grain of sand territory
2020-07-12T01:24:26 < Steffanx> Next project: glasses
2020-07-12T01:24:47 < zyp> as long as we're talking about imperial 0402, it's 1x0.5mm or so, that's not that small
2020-07-12T01:25:18 < strata> wait there's an imperial 0402 and a metric 0402 ?
2020-07-12T01:25:22 < strata> god damn you imperialists
2020-07-12T01:25:34 < zyp> yeah, metric 0402 is 0.4x0.2mm
2020-07-12T01:25:45 < Mangy_Dog> yeah tis confusing... and today i reminded myself how i get confussed over uf and nf :/
2020-07-12T01:25:49 < zyp> if that's a thing
2020-07-12T01:25:57 < Mangy_Dog> and when 0.1uf is 100nf

2020-07-12T01:28:00 < Mangy_Dog> also waiting for oven to cool
2020-07-12T01:28:06 < Mangy_Dog> but looked like it went ok....
2020-07-12T01:28:07 < Mangy_Dog> not perfect
2020-07-12T01:28:13 < zyp> you don't have a cooling fan?
2020-07-12T01:28:19 < Mangy_Dog> i saw one or two bridges and one led didnt settle quite straight

2020-07-12T01:28:39 < Mangy_Dog> just open the oven door
2020-07-12T01:29:11 < zyp> gets hard to do cooling profiles like that :)

2020-07-12T02:35:09 < R2COM> zyp i got the main idea from your file, i think i can craft my own scons file now
2020-07-12T02:35:33 < R2COM> zyp the only thing im still wondering is - is it a good style to insclude SConscript file every time?
2020-07-12T02:35:51 < R2COM> since as far as i know, the must have file is - SConstruct
2020-07-12T02:36:12 < R2COM> and i think it must be called exactlyu like that - "SConscript"
2020-07-12T02:36:14 < R2COM> errr
2020-07-12T02:36:16 < R2COM> SCOnstruct
2020-07-12T02:36:20 < R2COM> SConstruct
2020-07-12T02:36:31 < R2COM> but, the name of "SConscript" file can be literally anything
2020-07-12T02:38:47 < R2COM> correct me if im wrong
2020-07-12T02:44:09 < karlp> it can be yes. just like makefiles
2020-07-12T02:44:30 < karlp> scons -f blah.hoho
2020-07-12T02:44:37 < karlp> == just like make even
2020-07-12T02:46:44 < R2COM> technically you can just have 1 file - SConstruct and thats it
2020-07-12T02:47:04 < R2COM> i mean one can put all his "things to do" just there
2020-07-12T02:48:32 < karlp> yeah, that's style

2020-07-13T00:01:56 < karlp> measuring erosion by how much light is on the tube length or something?
2020-07-13T00:04:18 < qyx> yeah
2020-07-13T00:05:12 < qyx> mhm, I should check if 4L is ~cheap for such dimensions
2020-07-13T00:06:44 < qyx> O_o jlcpcb quotes 400x10mm for 4.60e
2020-07-13T00:06:56 < qyx> 2L though
2020-07-13T00:07:10 < qyx> 4L is ~30e for anything bigger than 100mm
2020-07-13T00:18:03 < kakimir> Steffanx: you said it not me
2020-07-13T00:20:52 < Steffanx> How bad is the erosion down there, kakimir ?
2020-07-13T00:21:17 < kakimir> is that tube errosion measurement device?
2020-07-13T00:21:25 < kakimir> *erosion
2020-07-13T00:21:56 < kakimir> https://www.youtube.com/watch?v=uzS3WG6__G4 musics for mr. S
2020-07-13T00:27:52 < Steffanx> How does this thing work, with light?  But how, mr qyx?
2020-07-13T00:30:10 < qyx> there are 64 phototransistors on the other side
2020-07-13T00:31:16 < kakimir> so you ram that tube in a soil and daylight is used to indicate erosion?
2020-07-13T00:31:31 < qyx> the light approach is not the best as it is not able to detect events during night rainfalls
2020-07-13T00:31:42 < qyx> yes, google for peep sensor
2020-07-13T00:32:24 < kakimir> that thing looks too expensive for something you plant into earth and potentially forget
2020-07-13T00:32:32 < kakimir> and plant dozens of them
2020-07-13T00:32:38 < kakimir> it's the amount of muxes
2020-07-13T00:33:14 < qyx> muxes are probably the cheapest part
2020-07-13T00:33:23 < kakimir> true
2020-07-13T00:34:40 < qyx> it is possible to use narrow solar cells
2020-07-13T00:35:26 < qyx> but the assembly is more complicated and the results are worse
2020-07-13T00:36:50 < qyx> eg. if the pin is planted in a vegetationb, it is hard to estimate the exact ground level by the cell's photocurrent
2020-07-13T00:39:21 < kakimir> true
2020-07-13T00:39:27 < kakimir> phototransistors are expensives
2020-07-13T00:40:31 < kakimir> would physical resonance be used to measure amount of soil?
2020-07-13T00:40:48 < kakimir> rod that has piezo element connected to top of it
2020-07-13T00:44:09 < kakimir> it would work if soil was completelly rigid
2020-07-13T00:44:18 < kakimir> but usually it's not the case
2020-07-13T00:44:52 < kakimir> you know what is cheap qyx? piezo elements
2020-07-13T00:45:36 < kakimir> at least those piezo coin shape things but idk. about smaller ones

2020-07-13T01:28:42 < karlp> aandrew: what was the missing bits? what did you need to get the BMP for?
2020-07-13T01:30:44 < aandrew> I didn't have to get the BMP, just want to play with it to see whawt all the fuss is about
2020-07-13T01:30:59 < aandrew> the issue was that openocd and jaylink don't like each other
2020-07-13T01:31:29 < karlp> were you using libjaylink bundled with oocd or what?
2020-07-13T01:31:43 < aandrew> built from git and also tried 0.10.0
2020-07-13T01:31:45 < karlp> that's had docs from segger contributed to it, it's got no real reason not to wkr.
2020-07-13T01:31:47 < aandrew> both had the same error
2020-07-13T01:31:51  * karlp shrugs
2020-07-13T01:32:11 < karlp> I know zapb who looks after the libjaylink does trace stuff with it, so kinda surprised
2020-07-13T01:32:13 < aandrew> yeah the second you try to read data over swo you get unspecified errors
2020-07-13T01:32:24 < aandrew> I'm probably doing something stupid but no idea what it would be
2020-07-13T01:32:26 < karlp> ah well.
2020-07-13T01:32:42 < karlp> so what was the final then? segger jlinkgdbserver? why does their gdb bit get involved?
2020-07-13T01:32:54 < aandrew> I've never had luck wtih jlink and openocd, and only slightly better luck with stlink and openocd
2020-07-13T01:33:30 < aandrew> karlp: well orbuculum likes jlinkgdbserver so that's where the involvement is, and there's a bunch of helper scripts for writing to DWT/ITM to configure it
2020-07-13T01:33:34 < aandrew> and they're all gdb based
2020-07-13T01:34:17 < karlp> yeah, that' sall because orbculum, for all it's good bits, lives in this weird world where you do that via your own scripts, and it's all assumed to be a bmp, isntead of just expecting your debugger to handle it properly.
2020-07-13T01:34:32 < karlp> there's some truly fucking odd thing sin orbuclum project :)
2020-07-13T01:35:10 < karlp> initially, I had to have oocd save the stlink trace to a file, thenn netcat to a port to make it look like jlinkserver thing
2020-07-13T01:35:19 < karlp> they had no comprehension of other options.

2020-07-13T04:26:08 < upgrdman> seems like shit encoding logic. not sure if all VNC stuff is like that, or just realvnc. like dragging a window around the screen causes LOTs of network traffic, like its sending the whole screen each frame, instead of a delta?

2020-07-13T07:45:13 < Cracki> upgrdman, window dragging probably needs client and server to know and allow "copyrect encoding", and for the server to be aware of windows and that they're moving. if it's "one big surface" it actually only sees differences and transmits those. I don't see much intelligence in many VNC/whatever projects
2020-07-13T07:45:53 < upgrdman> k
2020-07-13T07:46:21 < Cracki> it helps if the background/wallpaper is a flat color so it doesn't have to spend effort to encode that
2020-07-13T07:46:34 < upgrdman> k, i'll try that
2020-07-13T07:48:31 < Cracki> the best I've ever seen is windows native RDP and teamviewer because they take the compositing information and literally just transmit window moves, and maybe if a program redraws its window. teamviewer is all-commercial now tho, no more free lunch.
2020-07-13T07:49:15 < Cracki> even the TV-"fork" called anydesk is being retarded about things. they focus their energy on smart encoding schemes instead of grabbing information as early as possible.
2020-07-13T07:49:46 < Cracki> lots of VNC/RDP/... is just giving up and working from a single full screen buffer
2020-07-13T07:52:00 < Cracki> all the advice like "disable win7 aero" is because of that. windows DWM has an api that gives you an rgba picture of every window. they could use that to keep the "scene graph" around.
2020-07-13T07:52:58 < Cracki> VNC's client model is that you have a big buffer, and a piece of that is shown (you have off-screen area you can use). that would allow copyrect-based "compositing" even on dumb clients, so long as they implement the protocol as it has been for decades.

2020-07-13T12:59:08 < t4nk_freenode> ok, so I got them there stm32 boards.. got stm32cubeide installed in linux... thought it was funny at first.
2020-07-13T12:59:15 < t4nk_freenode> now I don't ;)
2020-07-13T13:00:03 < t4nk_freenode> what would be some alternatives to develop?
2020-07-13T13:00:10 < t4nk_freenode> and no, no ada for me thank you
2020-07-13T13:00:59 < t4nk_freenode> but this cubeide.. has so many silly things methinks
2020-07-13T13:01:57 < t4nk_freenode> let alone the unreadable color schemes
2020-07-13T13:06:17 < qyx> I am using the ARM GCC toolchain, make/scons, geany, openocd, libopencm3 as a HAL
2020-07-13T13:06:21 < t4nk_freenode> I was also trying to find out how to run a timer in oc mode, but slap my thighs and call me nancy twice if there's anything clear out there :|

2020-07-13T13:29:28 < t4nk_freenode> lol, installed geany on a kde dark theme
2020-07-13T13:35:19 < t4nk_freenode> phew.. that's better
2020-07-13T13:39:44 < qyx> why not kate on kde?
2020-07-13T13:39:54 < qyx> or even kdevelop
2020-07-13T13:40:13 < qyx> also, kde, dark, wut
2020-07-13T13:40:20 < t4nk_freenode> I got kate
2020-07-13T13:40:48 < t4nk_freenode> used kdevelop... like.. decades ago last ;)
2020-07-13T13:41:15 < qyx> just curious
2020-07-13T13:41:29 < qyx> I used kate in the past
2020-07-13T13:41:44 < qyx> on kde 2.something
2020-07-13T13:42:30 < t4nk_freenode> but I don't think it's about the editor.. I'm looking to install that toolchain on gentoo
2020-07-13T13:43:29 < t4nk_freenode> editor would only be nice if it came with some decent auto-completion, that's also lousy in cubeide
2020-07-13T13:44:17 < t4nk_freenode> my initial thoughts were that it was handy to get something going on an stm32.. especially compared to pic
2020-07-13T13:45:18 < t4nk_freenode> but it turns out that there are so many quirks and whatnot, it's just greatly confusing

2020-07-13T14:45:53 < Cracki> maybe microsoft should forget making browsers. they got better market share with vscode
2020-07-13T14:46:48 < jadew> t4nk_freenode, it's the best editor out there at the moment
2020-07-13T14:47:02 < benishor> there are other good ones
2020-07-13T14:47:04 < jadew> and works fairly well as an IDE
2020-07-13T14:47:07 < benishor> they ripped off a lot from sublime
2020-07-13T14:47:23 < jadew> they copied features, yeah
2020-07-13T14:47:25 < Cracki> sublime is having zero developers working on it
2020-07-13T14:47:32 < jadew> but I think they ripped off atom
2020-07-13T14:47:38 < benishor> atom ripped off sublime
2020-07-13T14:47:42 < jadew> yeah
2020-07-13T14:47:47 < Cracki> so yes, bow to sublime for innovating but vscode throws superior autocompletion on it
2020-07-13T14:47:50 < jadew> unfortunately atom is shit code wise
2020-07-13T14:47:57 < jadew> because of that stupid coffeescript
2020-07-13T14:48:02 < Cracki> isn't vscode atom-based? or electron?
2020-07-13T14:48:02 < benishor> yeah, vscode does pretty good
2020-07-13T14:48:06 < jadew> and it's poorly developed
2020-07-13T14:48:07 < benishor> electron
2020-07-13T14:48:07 < Cracki> or did ms develop electron
2020-07-13T14:48:12 < jadew> Cracki, it's electron
2020-07-13T14:48:37 < Cracki> eh, all the same anyway
2020-07-13T14:48:38 < t4nk_freenode> I don't think software with trackers and whatnot... can never be the best, but is a no-go, period
2020-07-13T14:48:55 < jadew> what trackers?
2020-07-13T14:48:58 < t4nk_freenode> couple of double negatives there, but you know what I mean
2020-07-13T14:49:46 < jadew> the thing is, VS Code is delivering great editing experience, has MS-level architecture, and is cross-platform
2020-07-13T14:50:07 < jadew> it's also extremely extendable and already has IDE support built in
2020-07-13T14:50:16 < jadew> I see no reason why it won't take over
2020-07-13T14:50:33 < t4nk_freenode> you're a windows user, right?
2020-07-13T14:50:43 < jadew> primarily, yeah
2020-07-13T14:50:47 < Cracki> pr0s use windows
2020-07-13T14:50:55 < Cracki> linux on the desktop, hah
2020-07-13T14:51:02 < t4nk_freenode> hehe, it was a trick question, jadew :b
2020-07-13T14:51:08 < t4nk_freenode> I knew the answer beforehand
2020-07-13T14:51:48 < jadew> well, I like my OS to work
2020-07-13T14:52:07 < t4nk_freenode> you got me there!
2020-07-13T14:52:41 < jadew> but it doesn't matter, VS code is cross platform
2020-07-13T14:52:44 < jadew> and free
2020-07-13T14:52:59 < jadew> which is all that linux users care about
2020-07-13T14:53:08 < jadew> all that commie BS, is just that, commie BS
2020-07-13T14:53:19 < t4nk_freenode> lol
2020-07-13T14:53:26 < t4nk_freenode> you seem to be able to speak for me
2020-07-13T14:53:53 < jadew> they just care about free - the moral highground is just a way of rationalizing their choice for free shit
2020-07-13T14:54:07 < jadew> and an attempt to force developers to work for free
2020-07-13T14:54:13 < t4nk_freenode> lol
2020-07-13T14:54:43 < Cracki> they care about free shit as in "free beer" because they certainly don't care about free as in "free speech".
2020-07-13T14:55:02 < t4nk_freenode> perhaps windows is just the only opportunity for total brainless idiots to chance at conning together an income?
2020-07-13T14:55:14 < Cracki> shit praxis too! they could be stealing from capitalists (piracy) but that's a no-no
2020-07-13T14:56:32 < Cracki> when you show them something you built, they always ask "is it open source" and "is it on github"
2020-07-13T14:56:44 < t4nk_freenode> well, I agree on that
2020-07-13T14:57:01 < Cracki> so entitled, like they were born with a silver spoon up their asses
2020-07-13T14:57:10 < t4nk_freenode> I will publish what I want, and when I want it..
2020-07-13T14:57:11 < Cracki> not even a thank you, just gib gib gib
2020-07-13T14:57:59 < zyp> protip: vscode works on macos too, if you wanna hate both windows and the commies
2020-07-13T14:58:08 < t4nk_freenode> lol
2020-07-13T14:58:10 < t4nk_freenode> hehe
2020-07-13T14:58:28 < Cracki> I think vscode isn't artsy enough for macos
2020-07-13T14:58:34 < zyp> I use it
2020-07-13T14:58:41 < Cracki> >_>
2020-07-13T14:58:49 < Cracki> did you own a newton?
2020-07-13T14:58:54 < zyp> a what?
2020-07-13T14:58:58 < Cracki> aaaaaah
2020-07-13T14:59:16 < Cracki> I was trying to give you a chance to save yourself!
2020-07-13T14:59:26 < Cracki> you coulda said yes
2020-07-13T14:59:55 < Cracki> the literature teacher at my high school owned one. didn't peg him for a techie but he was
2020-07-13T15:00:34 < Cracki> the newton is an overgrown palm pilot
2020-07-13T15:00:53 < Cracki> which is the predecessor to the iphone
2020-07-13T15:01:15 < Cracki> no i can't walk straight lines, yes I'm drunk how could you tell
2020-07-13T15:01:23 < zyp> I don't really care much for legacy apple stuff, I like macos for the unix
2020-07-13T15:01:52 < zyp> the way I see it, macos has both usable cli stuff and usable gui stuff
2020-07-13T15:02:15 < zyp> pick windows or linux and you are essentially picking one or the other
2020-07-13T15:02:32 < jadew> you have linux on windows now
2020-07-13T15:02:52 < zyp> I'm aware
2020-07-13T15:03:15 < jadew> it's pretty cool
2020-07-13T15:03:28 < zyp> yeah, I've used it
2020-07-13T15:03:41 < Cracki> call me superficial but I just can't bear apple's forced mouse acceleration and weird keyboard semantics. backspace doesn't backspace, delete doesn't delete, ctrl doesn't ctrl, alt doesn't alt, enter doesn't enter
2020-07-13T15:04:10 < Cracki> it's an evil parallel universe where the household appliances wear moustaches
2020-07-13T15:04:40 < zyp> Cracki, uh, I don't get the point you're trying to make about the keyboard
2020-07-13T15:04:50 < jadew> my wife is a macos user and I always have a difficult time using her laptop
2020-07-13T15:04:58 < zyp> I see the argument about ctrl/cmd, but all the other keys behaves the same, no?
2020-07-13T15:05:05 < Cracki> I sat in front of an apple once. everything didn't behave as I'm used to.
2020-07-13T15:05:14 < Cracki> in the "finder"
2020-07-13T15:05:22 < qyx> jadew: that depends on the point of view, I like my OS to work too
2020-07-13T15:05:26 < Cracki> I think I tried to enter a folder using "enter". didn't work
2020-07-13T15:05:36 < Cracki> I think i tried to delete a file with delete, didn't work
2020-07-13T15:05:37 < t4nk_freenode> lol qyx 
2020-07-13T15:05:52 < t4nk_freenode> I just didn't bother to respond :)
2020-07-13T15:05:58 < zyp> oh, I thought you were talking about text editing
2020-07-13T15:06:07 < Cracki> no, even before text editing
2020-07-13T15:06:49 < Cracki> I mean, even windows and linux have *that* stuff in common
2020-07-13T15:06:58 < jadew> you can move and delete files from vs code, so have that start at boot time
2020-07-13T15:07:07 < zyp> haha
2020-07-13T15:07:14 < Cracki> no, emacs is the only true bootloader
2020-07-13T15:07:26 < Cracki> if you use vim as a bootloader, you're weird
2020-07-13T15:07:40 < zyp> I use the vim plugin for vscode
2020-07-13T15:07:59 < Cracki> use the vscode plugin for vim... wait, is vimscript still a thing or did they come to their senses?
2020-07-13T15:08:15 < Cracki> they saw perl and thought, that's not enough line noise
2020-07-13T15:08:27 < jadew> zyp, what does that plugin do?
2020-07-13T15:08:39 < jadew> it makes it behave like vim?
2020-07-13T15:08:43 < jadew> yy and all that?
2020-07-13T15:08:45 < Cracki> they saw a keyboard and thought, boy do I want a washing machine with toggle switches for entering program code
2020-07-13T15:08:48 < zyp> jadew, yeah
2020-07-13T15:09:33 < zyp> I switched from macvim
2020-07-13T15:10:09 < zyp> and I've been using vscode on windows at work for a couple of years because gvim plain sucks
2020-07-13T15:10:37 < jadew> can you still make use of the other features in vscode when that plugin is enabled?
2020-07-13T15:10:46 < jadew> for example, commenting blocks, moving things around
2020-07-13T15:10:55 < jadew> multi cursors?
2020-07-13T15:11:46 < zyp> I assume so
2020-07-13T15:13:02 < zyp> what do you mean by multi cursors?
2020-07-13T15:13:16 < jadew> you can edit multiple things at once
2020-07-13T15:14:23 < zyp> I generally uses vim's visual block mode to do that
2020-07-13T15:14:26 < jadew> https://i.stack.imgur.com/MayEK.gif
2020-07-13T15:15:20 < zyp> huh, haven't tried doing that
2020-07-13T15:15:37 < jadew> it's pretty neat, I use multicursors all the time
2020-07-13T15:16:05 < jadew> you can create a long cursor vertically too
2020-07-13T15:16:07 < zyp> but when editing the same thing on a bunch of lines I hit ctrl-v to enter visual block, select the block I want to edit, and then c or I or whatever to start editing
2020-07-13T15:16:25 < jadew> so if you have a list of things, each on a new line, you can modify the whole thing at once
2020-07-13T15:16:30 < zyp> yeah
2020-07-13T15:16:35 < jadew> and for example, quote them, initialize them, etc
2020-07-13T15:16:42 < zyp> that's what I do, with vim shortcuts
2020-07-13T15:16:48 < jadew> I see
2020-07-13T15:17:04 < zyp> that's also what I generally do to comment and uncomment code
2020-07-13T15:17:12 < jadew> with vscode you just keep alt and shift pressed anddrag down
2020-07-13T15:17:19 < jadew> you can do it by keyboard too
2020-07-13T15:18:05 < zyp> but anyway, I've used the «jump to definition» and similar shortcuts before
2020-07-13T15:18:21 < zyp> they work in parallel with the vim keybindings
2020-07-13T15:18:33 < jadew> that's cool
2020-07-13T15:22:58 < jadew> final version of that thing I made: https://cojotech.com/media/images/llna-030-10.jpg

2020-07-13T15:25:46 < t4nk_freenode> the commie version!
2020-07-13T15:25:53 < jadew> haha
2020-07-13T15:26:15 < jadew> it's really a good editor, make sure to check the extensions tho
2020-07-13T15:26:17 < jadew> they add a lot
2020-07-13T15:26:57 < jadew> I recommend the Project Manager extension at the very least
2020-07-13T15:27:21 < jadew> you can then switch between projects with alt+shift+p
2020-07-13T15:27:45 < t4nk_freenode> I added it while you spoke

2020-07-13T23:37:17 < Cracki> heh
2020-07-13T23:40:32 < Steffanx> How annoyed are you by those scratches jadew?
2020-07-13T23:40:43 < jadew> though the roof
2020-07-13T23:41:04 < jadew> they messed up the cover plates exactly on the customer-facing side
2020-07-13T23:41:41 < jadew> I think they either put them on something dirty after they got machined or they did that when cleaning the edges
2020-07-13T23:41:52 < Steffanx> Couldnt they polish it a bit more?
2020-07-13T23:42:01 < jadew> I made a point of "no sharp edges or corners" thing, so I think they went a little overboard with it
2020-07-13T23:42:30 < jadew> if you polish it to get those scratches out, you end up with too much of a mirror finish
2020-07-13T23:42:56 < Steffanx> Which is nice :P

2020-07-13T23:43:14 < jadew> heh, maybe...
2020-07-13T23:43:18 < Cracki> so you "polish" it with coarser stuff
2020-07-13T23:43:30 < jadew> right... well, I didn't have any control over this stuff
2020-07-13T23:43:40 < jadew> and I didn't want to do it myself because I was afraid I'd make it worse
2020-07-13T23:43:44 < Cracki> eh, next batch
2020-07-13T23:44:03 < jadew> yeah, on the next ones I'll make sure to tell them about it
2020-07-13T23:44:15 < jadew> although, I might look for a different shop
2020-07-13T23:44:16 < Cracki> this is probably 5 minutes of work for them to fix
2020-07-13T23:44:28 < jadew> yeah
2020-07-13T23:45:00 < jadew> the scratches were less visible on the raw brass
2020-07-13T23:45:31 < jadew> Steffanx, where did you see them tho? I didn't think they're that visible in those pictures
2020-07-13T23:46:37 < jadew> oh, next to the right connector in the front one
2020-07-13T23:46:48 < Cracki> I only see milling on those silvery parts
2020-07-13T23:46:50 < jadew> yeah... there are more like that
2020-07-13T23:46:57 < Cracki> oh that, that's not nice
2020-07-13T23:47:14 < jadew> yeah
2020-07-13T23:49:03 < jadew> I'm not very happy about the way they dulled the edges either
2020-07-13T23:49:42 < jadew> I'll add a tiny chamfer on the next ones instead
2020-07-13T23:49:57 < jadew> although, I had issues with chamfers too, but not with this shop
2020-07-13T23:53:50 < jadew> these guys seem to work best with aluminium
2020-07-13T23:54:00 < jadew> the aluminium parts were all pretty good

2020-07-14T08:45:25 < aandrew> wtf
2020-07-14T08:45:58 < aandrew> 3.3V, ADC can run at 30MHz (33.3ns/ADC clock cycle)
2020-07-14T08:46:38 < aandrew> 10 bits can be done in as little as 3+10 cycles, but ADC_SMPR's lowest without going under is 15 cycles
2020-07-14T08:47:22 < aandrew> so. 15 cycles, 33.3ns/cycle = 500ns for a conversion. Does that sound right?

2020-07-15T02:26:37 < Laurenceb> The approximate costs for producing 6kW power via a Twin Cylinder Piston Engine Electrical Generator is 6K GBP including the generator. After this capital cost, there is no fuel cost. The system can reuse the H2O (Water) repeatedly by capturing it from the exhaust.

2020-07-15T13:21:14 < zyp> by following the standard chunking rules
2020-07-15T13:22:16 < zyp> a usb transfer consists of zero or more MPS-sized packets and one smaller packet
2020-07-15T13:23:27 < zyp> also this doesn't have anything to do with libusb, every high level API should work the same way
2020-07-15T13:24:20 < dongs> uh ya well
2020-07-15T13:24:38 < dongs> also god damn FUCK libusb on windows
2020-07-15T13:24:45 < dongs> locked up all my desktop USB ports for the 2nd time in like 5 mins
2020-07-15T13:24:56 < dongs> i have to shutdown and reboot everything not otm ention close all the shit i have open

2020-07-15T13:25:02 < zyp> haha
2020-07-15T13:25:24 < zyp> sounds more like a windows issue than a libusb issue
2020-07-15T13:25:33 < zyp> you're using the winusb backend, right?
2020-07-15T13:30:45 < dongs> yeah
2020-07-15T13:33:22 < zyp> not libusb's fault winusb can't keep userspace shit from locking up the entire kernel stack :p
2020-07-15T13:33:44 < zyp> and to be fair I've managed the same on macos
2020-07-15T13:34:15 < zyp> I think it's more likely from the device behaving weird than libusb

2020-07-15T15:27:04 < Cracki> how sad is it that we have to use technology to show things that are obscured by technology
2020-07-15T15:27:14 < Mangy_Dog> right now im jumbled up between index or HP reverb g2
2020-07-15T15:27:49 < jadew> I wish I lived on a farm or in some remote location, so I could have a telescope
2020-07-15T15:27:53 < jadew> I think my son would love it
2020-07-15T15:27:56 < Cracki> oh I'm kinda curious about the (simple) mechanics of earth and sun... and how that pertains to sun dials
2020-07-15T15:28:08 < Mangy_Dog> index = knuckles and more preceise tracking.... G2= OMFG LOVELY DISPLAY, but inside out tracking and mediocer controllers
2020-07-15T15:28:34 < Cracki> illustrating that in 3d would be simple and understandable. all the shit drawings I've seen are shit drawings and show nothing
2020-07-15T15:28:44 < jadew> Mangy_Dog, I wasn't aware of those two
2020-07-15T15:28:47 < Mangy_Dog> G2s display is basicaly .... the utterly best display there is in the VR market
2020-07-15T15:28:55 < Mangy_Dog> vavle index?
2020-07-15T15:29:13 < Mangy_Dog> its basically when vavle split away from HTC
2020-07-15T15:29:15 < jadew> Cracki, yeah, lots of things would be better described in a VR environment
2020-07-15T15:29:19 < Mangy_Dog> and made there own
2020-07-15T15:29:30 < Cracki> not even vr, just... interactively explorable 3d graphics
2020-07-15T15:30:17 < Cracki> like... switching viewpoints between solar system, earth surface, ...
2020-07-15T15:30:42 < Mangy_Dog> HPg2 reverb is also 600 dollars
2020-07-15T15:30:46 < Mangy_Dog> and index is 1000
2020-07-15T15:30:52 < Cracki> oooooh they spent money on the art department https://www.youtube.com/watch?v=Bxp9xxgEfak
2020-07-15T15:31:17 < Cracki> what are "mura-free" lcd panels
2020-07-15T15:31:22 < Cracki> plural of moire?
2020-07-15T15:31:26 < Mangy_Dog> can some one explain to me why though that the index in america is 1000 but in the uk its only 913... I know the pound is really shit at the moment... and exchange rates suck but.... its not THAT level of bad
2020-07-15T15:31:49 < Cracki> because uk coins are worth more than yankee coins
2020-07-15T15:32:06 < Cracki> oh, you mean it costs more even considering exchange?
2020-07-15T15:32:21 < Cracki> perhaps they think brits are loaded
2020-07-15T15:32:28 < Cracki> or import/export taxes
2020-07-15T15:32:30 < Mangy_Dog> were really REALLY not
2020-07-15T15:33:29 < Cracki> aha! mura... https://www.roadtovr.com/whats-the-difference-between-screen-door-effect-sde-mura-aliasing-vr-headset/
2020-07-15T15:34:39 < Cracki> 2Kx2K per eye, that's nice
2020-07-15T15:35:04 < jadew> did you find specs on the IPD?
2020-07-15T15:35:05 < Mangy_Dog> just a quick basic run down G2 has 2k screens per eye... the index is 1440 and the g2 also has better fenel lenses that seem to reduce god rays compaired to index
2020-07-15T15:35:12 < Mangy_Dog> both are adjustable
2020-07-15T15:35:25 < jadew> between what and what?
2020-07-15T15:35:30 < jadew> the vive doesn't work on kids for example
2020-07-15T15:35:35 < Mangy_Dog> also g2 seems to have a oled quality range of colours compared to index being typical lcd
2020-07-15T15:35:48 < Mangy_Dog> thoubh both cant do perfect black being both still being lcd
2020-07-15T15:36:03 < Mangy_Dog> how young a kid?
2020-07-15T15:36:07 < jadew> 7
2020-07-15T15:36:10 < Mangy_Dog> eeesh
2020-07-15T15:36:12 < Cracki> do they at least use millisecond exposure to reduce motion blur?
2020-07-15T15:36:19 < Mangy_Dog> i dont think youre going to find any VR working for a kid that young
2020-07-15T15:36:46 < Mangy_Dog> cracki i dont know but g2 is 90hz refresh and index is up to 140hz
2020-07-15T15:37:23 < Cracki> 90-144 hz is still 7-8 milliseconds
2020-07-15T15:37:44 < Cracki> motion blur is noticeable when eyes move across the screen, tracking a thing moving across the picture
2020-07-15T15:37:56 < Cracki> I think traditionally people called it "ghosting"
2020-07-15T15:38:19 < Cracki> but ghosting is a different thing, it's when the pixel's intensity doesn't drop step-wise but gradually
2020-07-15T15:38:58 < Cracki> you can see motion blur in LED displays like at bus stops or in store fronts, where text is scrolling through
2020-07-15T15:39:17 < Cracki> the leds flash very briefly. if they stayed on for the full duration of the frame, you'd see them as dashes
2020-07-15T15:41:37 < jadew> just bought fusion
2020-07-15T15:41:59 < Mangy_Dog> ahh ghosting 
2020-07-15T15:42:01 < Mangy_Dog> i see what you mean
2020-07-15T15:42:04 < Mangy_Dog> that i dont know
2020-07-15T15:42:13 < Mangy_Dog> im assuming its fairly low but maybe not perfect
2020-07-15T15:42:24 < Mangy_Dog> i dont think the 140 is over drived so i suspect teh ghosting is minimal
2020-07-15T15:42:33 < Mangy_Dog> fusion?
2020-07-15T15:42:37 < Cracki> 360
2020-07-15T15:42:41 < Cracki> autodesk
2020-07-15T15:42:46 < Mangy_Dog> you"brought" f360?
2020-07-15T15:42:52 < Cracki> seems they had a sale
2020-07-15T15:43:03 < jadew> yeah, 246 eur/yr
2020-07-15T15:43:11 < Cracki> brought with a hard r
2020-07-15T15:43:13 < Cracki> *bought
2020-07-15T15:43:14 < Mangy_Dog> but do you use it for work?
2020-07-15T15:43:35 < jadew> yeah, I haven't earned anything from it yet
2020-07-15T15:43:41 < jadew> but I am trying to sell those products
2020-07-15T15:43:45 < Mangy_Dog> same thats why i use the free version
2020-07-15T15:44:19 < Mangy_Dog> if i was actually regularly making money off it... ill probably subscribbe to it... as its then part of a buisness
2020-07-15T15:44:35 < jadew> I figured that eventually, I will start selling and it's better to take advantage of the offer
2020-07-15T15:44:43 < Mangy_Dog> but with the subscription policy change last year they took a gient massive dump on freelancers
2020-07-15T15:52:05 < jadew> they did, yeah

2020-07-15T23:29:47 < tcth> that´s nice to hear :)
2020-07-15T23:29:54 < tcth> Steffanx, I think that is a pretty self-sustaining process
2020-07-15T23:29:59 < jadew> *but after corona
2020-07-15T23:30:02 < tcth> certainly
2020-07-15T23:30:09 < tcth> how´s children-ing with corona?
2020-07-15T23:30:14 < jadew> difficult
2020-07-15T23:30:20 < tcth> I can imagine
2020-07-15T23:30:26 < tcth> Steffanx, oh, there is newz
2020-07-15T23:30:28 < tcth> I have a dog now
2020-07-15T23:30:31 < tcth> because reasons.
2020-07-15T23:30:35 < Steffanx> bwhahaha, lol what
2020-07-15T23:30:36 < sync> oof
2020-07-15T23:30:38 < Steffanx> YOU?
2020-07-15T23:30:48 < tcth> yup.
2020-07-15T23:32:27 < tcth> it´s that much of a drastic change that I almost forgot to mention it
2020-07-15T23:33:19 < jadew> tcth, I had this urge to take a break and go visit the world too
2020-07-15T23:33:25 < jadew> I regret not doing it
2020-07-15T23:33:37 < tcth> jadew, I really do not have even the slightest urge to visit the world
2020-07-15T23:33:45 < tcth> if at all - then the urge to visit people.

2020-07-15T23:38:52 < tcth> it´s basically blaxter in a dog: kinda smart and can get shit done but always has that tendency to be a pain in the butt.

2020-07-16T00:15:37 < Steffanx> Yet.
2020-07-16T00:15:47 < Steffanx> Till the winter comes
2020-07-16T00:15:49 < tcth> having him for like 6 weeks now
2020-07-16T00:15:58 < tcth> yeah he did do the winter -> summer transition at the beginning he got here
2020-07-16T00:16:00 < Steffanx> And then till the summer comes
2020-07-16T00:16:08 < tcth> but that was still moderate & very managable (very short hair)
2020-07-16T00:16:21 < Steffanx> Lucky you ;)
2020-07-16T00:17:18 < tcth> my gf choose this one very carefully to align with my sensitive preferences & expectations - and she did a great job there

2020-07-16T11:10:09 < PaulFertser> How to make people be nice though?
2020-07-16T11:10:18 < tcth> MDMA
2020-07-16T11:10:23 < tcth> mawk can supply
2020-07-16T11:10:50 < Guest89629> mind direct memory access
2020-07-16T11:11:06 < tcth> :D
2020-07-16T11:11:10 < PaulFertser> btw, in russia there's now an official law proposal (following the changes to the constitution) that's somehow supposed to prohibit transgenders to marry (at all anyhow).
2020-07-16T11:11:39 < tcth> PaulFertser, why? what´s the motivation?
2020-07-16T11:12:17 < PaulFertser> tcth: they added "marriage is an alliance of a man and a woman" to the constitution text. And probably they consider transgenders to be neither. idk really, they're all just sick.
2020-07-16T11:12:33 < PaulFertser> The majority of public doesn't seem to mind though.
2020-07-16T11:12:36 < PaulFertser> MDMA is banned
2020-07-16T11:12:41 < PaulFertser> So?
2020-07-16T11:13:24 < PaulFertser> How to make people be nice?
2020-07-16T11:13:37 < Guest89629> the motivation is simple, some people have personal hatred and love to dictate others how to live their lives even when when they do something is harmless
2020-07-16T11:14:19 < tcth> PaulFertser, I´m not a good person to ask such a question. I kind of always expect cooperation
2020-07-16T11:14:22 < Guest89629> most of it comes from the misguided application of induction "if everyone did it, there'd be bad consequences" and then "but then why are you special for being different"
2020-07-16T11:14:38 < tcth> I am really bad at motivating people that are not motivated. But I am good at pushing motivated people further.
2020-07-16T11:15:03 < PaulFertser> tcth: I mean probably PC bullshit is actually kinda working to slowly change the public opinion?
2020-07-16T11:15:25 < mawk> for the worse sure
2020-07-16T11:15:33 < mawk> the world is americanizing
2020-07-16T11:15:35 < Guest89629> hard to tell which is which
2020-07-16T11:15:49 < Guest89629> I mean which one is driving the other
2020-07-16T11:15:58 < tcth> PaulFertser, the way I am experiencing it in the western world is in most cases some over exaggerated bullshit to achieve something different than actually intended
2020-07-16T11:16:02 < catphish> stop feeding them conflicting, inflammatory views through the media they read, and instead let people talk and form their own opinions with others?
2020-07-16T11:16:35 < PaulFertser> tcth: that's how you, a smart person, perceive it. But what about the common people?
2020-07-16T11:16:55 < mawk> we need an indignation translator
2020-07-16T11:17:06 < catphish> basically, we need to stop this: https://i.imgur.com/ZCS5OFR.jpg
2020-07-16T11:17:07 < Guest89629> virtue signaling
2020-07-16T11:17:08 < mawk> "taking racist offense for someone else" = "advancing indigenist agenda"
2020-07-16T11:17:13 < catphish> even when we agree, we disagree
2020-07-16T11:17:14 < tcth> PaulFertser, I percieve myself as a very common person.
2020-07-16T11:17:34 < PaulFertser> catphish: the views/opinions are inherently conflicting. Isn't it what different medias exist for, to express conflicting views?
2020-07-16T11:17:40 < tcth> catphish :D
2020-07-16T11:17:52 < tcth> +1
2020-07-16T11:17:58 < catphish> PaulFertser: except they aren't always conflicting
2020-07-16T11:18:00 < PaulFertser> tcth: I bet you're considerably smarter (in cognitive abilities sense) than most of the population.
2020-07-16T11:18:19 < tcth> PaulFertser, I truly hope that that is not the case. I do way too many dumb things for that. would be concerning.
2020-07-16T11:18:21 < catphish> PaulFertser: sometimes, the media drive a wedge for some reason other than genuine difference of opinion
2020-07-16T11:18:32 < mawk> all media are owned by billionnairs
2020-07-16T11:18:34 < PaulFertser> catphish: (your pic) isn't both articles true?
2020-07-16T11:18:35 < mawk> at least in france
2020-07-16T11:18:45 < Guest89629> the media often is not genuine in portraying the reality
2020-07-16T11:18:51 < mawk> they're all advancing political chess pieces to further their business; or a few have real ideology but that's still pretty bad
2020-07-16T11:19:10 < Guest89629> it's easy to fabricate contention by showing 2 opposite views, but not showing how much they are shared
2020-07-16T11:19:16 < mawk> 7 billionnaires own like 80% of all media, be it radio, written press, television, internet news
2020-07-16T11:19:21 < PaulFertser> tcth: haha, it IS CERTAINLY concerning when you think how many people are so fucking ridiculously bad at their jobs.
2020-07-16T11:19:24 < tcth> PaulFertser, in any case it doesn´t take a walking-talking-steven-hawking to realize that things like riots & vandalism is just stupid af - not even talking about the /real/ issues.
2020-07-16T11:19:35 < catphish> PaulFertser: probably technically yes, but they're both discussing policy from the UK's 2 main opposing political parties, something upon which they agree, but walk to divide people on anyway
2020-07-16T11:19:44 < catphish> *want to
2020-07-16T11:20:15 < tcth> the emotional instability of people man... seriously - sometimes I wonder how they even manage to choose which underwear to wear in the morning 
2020-07-16T11:20:21 < tcth> (heavy generalization ofc)
2020-07-16T11:20:40 < catphish> (i can't remember the word) but the current political system of some countries is highly divided right down the middle, people from the 2 sides are actively discouraged from agreeing on anything
2020-07-16T11:20:47 < PaulFertser> catphish: my main complaint about those articles would be lack of the citations to the actual research published in scientific journals.
2020-07-16T11:21:03 < tcth> PaulFertser, people´s jobs should not be related to people´s decision like racism and all that shit
2020-07-16T11:21:03 < catphish> PaulFertser: no, there's a much more obvious point
2020-07-16T11:21:21 < catphish> PaulFertser: the articles are basing their view of a policy not on the policy, but who is proposing it
2020-07-16T11:21:33 < PaulFertser> tcth: surely some get so enraged that they settle to wear none of that :)
2020-07-16T11:21:55 < tcth> PaulFertser, I certainly have a few friends where I think/know that they are intellectually a bit below average (personal opinion) but none of them is anywhere near as stupid enough to do ´all those things´
2020-07-16T11:22:05 < tcth> PaulFertser, :D
2020-07-16T11:22:44 < Guest89629> well, over millions people, you'll find plenty of lunatics
2020-07-16T11:22:55 < mawk> it's call cliving catphish 
2020-07-16T11:22:59 < mawk> if that's an english word
2020-07-16T11:23:27 < Guest89629> even if it's the 0.1% percent of a million people, 1k people is enough to set on fire a decent portion of a city
2020-07-16T11:23:43 < PaulFertser> catphish: clearly both articles are examples of journalists being poor at their job, as they provide just a single opinion and no background or alternative views there. Guess one is supposed to ignore media like that.
2020-07-16T11:23:46 < tcth> PaulFertser, personally I think that the core issue is that people bitch about things they know nothing about/did not think about properly. It´s something I have seen growing in the area I live in the past few years. People just complain and think they could do everything so much better and that everything is so much simpler in their view. I think it starts with that. If people would think about things before they complain things would start to head for a
2020-07-16T11:23:46 < tcth>  better direction
2020-07-16T11:24:06 < tcth> note that I am not a behavioral scientist or anything - I can be very wrong there. Also rather tired so my wording might be... sub-smart
2020-07-16T11:24:11 < catphish> PaulFertser: right, that's the point
2020-07-16T11:24:27 < catphish> PaulFertser: but sadly people will base their opinion on the policy on one of those 2 articles :(
2020-07-16T11:24:58 < PaulFertser> catphish: so for the kind of people that do that, probably the PC bullshit is working as intended?
2020-07-16T11:25:41 < Guest89629> I have mixed feelings about the consequence of PC bullshit
2020-07-16T11:25:47 < tcth> me too ^
2020-07-16T11:25:50 < Guest89629> it confuses equal opportunity with equal outcomes
2020-07-16T11:26:01 < Guest89629> take for example affirmative action
2020-07-16T11:26:15 < Guest89629> it tries to fix a bad thing with another bad thing
2020-07-16T11:26:57 < catphish> "PC bullshit" is a uselessly vague way to deride anything you disagree with, avoid it
2020-07-16T11:27:13 < PaulFertser> We have a saying that goes something like "you extract a wedge by hitting it with another wedge" :)
2020-07-16T11:27:15 < catphish> be specific about things you disapprove of and back it up :)
2020-07-16T11:29:01 < Steffanx> Im not even sure what "PC" is. Lol
2020-07-16T11:29:10 < Guest89629> politically correct
2020-07-16T11:29:17 < tcth> PaulFertser, BrainDamage - I really enjoy this conversation but unfortunately I am way too tired to keep up & bring in any valuable, correct input from my side. I´ll opt out of this for the moment - hopefully another time :)
2020-07-16T11:29:21 < Steffanx> Oh, lol
2020-07-16T11:29:44 < Steffanx> Time to get a ' key, tcth 
2020-07-16T11:29:48 < Guest89629> which in this case I think it's a proxy for virtue signaling
2020-07-16T11:30:26 < PaulFertser> Steffanx: are you too old to watch "south park"?
2020-07-16T11:31:04 < Steffanx> I dont watch south park 
2020-07-16T11:31:10 < Steffanx> Its often too unfunny
2020-07-16T11:31:12 < tcth> you´re missing out
2020-07-16T11:31:13 < catphish> it's basically a way for people to describe actions that in their opinion excessively favour diversity, inclusivity, acceptance, often through meaningless acts like choice of words
2020-07-16T11:31:13 < tcth> what.
2020-07-16T11:31:18 < Steffanx> So i dont waste my time on that
2020-07-16T11:31:28 < tcth> better waste your time smart tweezing? :p
2020-07-16T11:31:36 < Steffanx> No
2020-07-16T11:32:10 < Steffanx> You're awfully out of date tcth :P
2020-07-16T11:32:31 < tcth> yeah, I am getting old :(
2020-07-16T11:33:59 < PaulFertser> I like your choice of words catphish :)
2020-07-16T11:34:37 < catphish> i'm mostly just a fan of everyone getting along
2020-07-16T11:41:19 < PaulFertser> Sometimes by being too nice you're risking to be taken advantage of/abused by the people who are not really nice and have their own intentions and evil plans. So "xenophobia" is in fact an essential safety measure in many circumstances. Where to draw the line then?
2020-07-16T11:42:10 < catphish> the trick is to assess people individually i guess
2020-07-16T11:43:10 < PaulFertser> The judgement is still to be made.
2020-07-16T11:46:13 < PaulFertser> Also, they usually say that prejudice is a bad thing. Now imagine I'm riding a motor bike and I see a taxi or car-sharing or BMW or a car from Cechnya region. Is that a bad thing that I would raise my awareness and would try to keep farther from them?
2020-07-16T11:52:32 < PaulFertser> In other words, prejudice is one of the risk-management tools. 
2020-07-16T11:52:57 < catphish> that's absolutely true and unavoidable
2020-07-16T11:54:09 < catphish> it's just a matter of doing it correctly and not being afraid of things that have no real potential to harm you, such as homosexuals
2020-07-16T11:54:48 < catphish> groups of youths with hoodies and knives tucked into their belt, sure
2020-07-16T11:56:47 < PaulFertser> Also, when many LGBT activists say that "it's not a choice", I'd say that's not really accurate either. Looks like it's _not always_ a choice. But it seems that many people are "bisexual enough" to be actually choosing. So "gay propaganda" may be working to an extent. So when you say "I want my child to become an engineer" it sounds normal but when you say "I want my child to be straight and so
2020-07-16T11:56:53 < PaulFertser> please restrict the gay propaganda" it's supposed to be highly offensive. But it seems there's actually some substance in that.
2020-07-16T12:03:47 < PaulFertser> Many people think that they know better how to make their children happy. But are they really wrong most of the time?
2020-07-16T12:07:52 < dongs> if I want to send stuff at xxmbit/sec do I just count the bits, send that many, then wait until 1sec is over?
2020-07-16T12:08:02 < dongs> is there a less retarded approach?
2020-07-16T12:08:14 < dongs> (over UDP or something, so its not  really to timing critical)
2020-07-16T12:14:34 < tcth> hi dongs
2020-07-16T12:14:36 < tcth> sup?
2020-07-16T12:20:14 < PaulFertser> dongs: if you're sending UDP too fast then some router in-between might just drop some, being limited by the bandwidth and buffer sizes.
2020-07-16T12:30:22 < zyp> dongs, if you wanna send stuff at a given rate and you don't care about flow control or error handling, you just pick a packet size and then figure out what interval you need to send them at
2020-07-16T12:30:56 < zyp> e.g. if you wanna send 100kB/s and you're sending 1000B packets, you need to send 100 per second, so one every 10ms
2020-07-16T12:31:19 < PaulFertser> Yes, imitating that with bursts might not always work as you want it.
2020-07-16T12:33:39 < zyp> on the other hand, why do you want to send at a fixed rate? normally you'd want to find the max speed of the link, unless you're only getting fed data at a fixed rate
2020-07-16T12:33:57 < zyp> and in the latter case you'd just send as soon as you have a new packet's worth of data

2020-07-16T13:24:35 < veverak> there is also approach to send "time_from_last*rate" bytes when function is called
2020-07-16T13:24:54 < veverak> so you can vary the time between sends and the speed is +- same
2020-07-16T13:36:33 < dongs> zyp, no, it has to be fixed rate
2020-07-16T13:36:36 < dongs> and packets arent same size
2020-07-16T13:37:12 < dongs> https://i.imgur.com/WyL9ypA.png
2020-07-16T13:37:29 < dongs> this is on LAN so router etc hsouldnt matter
2020-07-16T13:46:46 < zyp> why does it have to be fixed rate?
2020-07-16T13:47:07 < dongs> because the result goes to RF at a fixed rate
2020-07-16T13:47:31 < dongs> there's some buffering as far as I understand, but Ineed to keep the buffer filled up
2020-07-16T13:47:31 < zyp> sounds like you need flow control
2020-07-16T13:48:08 < dongs> yes but the receiver is just a dumb device which takes stuff from UDP and has no two-way flow control comms
2020-07-16T13:48:26 < Steffanx> Lol. Proper engineering.
2020-07-16T13:48:41 < dongs> its like a $10k device too
2020-07-16T13:48:48 < dongs> so very proper for sure
2020-07-16T13:49:39 < zyp> how do you know how full the buffer is? what happens if it over- or underflows?
2020-07-16T13:50:03 < dongs> i dont, which is why I should take best effort to send it at the rate it expects
2020-07-16T13:50:31 < zyp> is this TS shit? are there some timestamps in the package you can look at?
2020-07-16T13:50:39 < dongs> no timestamps, not ts
2020-07-16T13:50:53 < dongs> i suppose I could call the mfg tomorrow and ask i there's a way to get fifo / buffer status
2020-07-16T13:50:58 < dongs> but I guess the answer will be no
2020-07-16T13:51:29 < dongs> the device plays back pre-generated files that are made to be at a given rate
2020-07-16T13:51:37 < dongs> i think taking input from netwrok was an afterthought
2020-07-16T13:52:12 < dongs> hmm actually there might be ntp timestamps in teh data
2020-07-16T13:52:24 < zyp> thing is, unless you're deriving playback speed and the other thing from the same clock then you will never get exactly the same rate, 
2020-07-16T13:52:32 < dongs> right...
2020-07-16T13:52:45 < zyp> which means that it'll either overflow or underflow eventually, and is that a big deal?
2020-07-16T13:52:45 < dongs> i guess i gotta call and see wtf
2020-07-16T13:52:56 < dongs> yeah, that doesnt work if it *flows
2020-07-16T13:53:09 < dongs> either over or under would be fail :)
2020-07-16T13:53:14 < zyp> if it can't cope with lost data then you absolutely need flow control
2020-07-16T13:53:39 < zyp> without it, all you can do is try to reduce how often it happens
2020-07-16T13:54:21 < dongs> i wonder how the fuck is it even going to work, I guess im gonna need some kinda side channel to tell fifo load
2020-07-16T13:54:34 < dongs> cuz right now the only spec I have is just < 1500 bytes UDP packets
2020-07-16T13:54:41 < dongs> that it will accept at given IP/port
2020-07-16T13:54:54 < zyp> regarding previous question: with varying packet size, all you have to do is vary the interval with the packet size
2020-07-16T13:55:36 < zyp> again, for 100kB/s, if you send 1000B, wait 10ms before you send the next, if you send 500B, wait 5ms before you send the next
2020-07-16T13:56:53 < zyp> use a freerunning timer with deadlines so you don't count 10ms plus the time spent sending a packet
2020-07-16T13:57:22 < zyp> interval is time from start of one packet to start of next
2020-07-16T13:57:49 < dongs> aight lemme fuck around with this and see
2020-07-16T13:58:20 < zyp> still gonna fuck up eventually, if not once an hour then maybe once a week, idk
2020-07-16T14:04:23 < dongs> right

2020-07-16T20:17:45 < mawk> Guest89629: f has at least 5 distinct zeroes, show that 8f''' + 12f'' + 6f' + f has at least 2 distinct zeroes
2020-07-16T20:17:47 < mawk> it's a very cool problem
2020-07-16T20:17:49 < mawk> CAS forbidden
2020-07-16T20:17:53 < mawk> or maybe authorized but then you must recite 3 hail mary
2020-07-16T20:49:37 < Steffanx> math, the only world where they make up their own problems :P
2020-07-16T21:26:13 < mawk> Steffanx :(
2020-07-16T21:35:18 < Thorn> this is an EE channel, only 2nd order polynomials are allowed
2020-07-16T21:36:18 < Steffanx> Lol mawk.
2020-07-16T21:36:43 < Steffanx> I only say this because issues like this are complete abracadabra for me
2020-07-16T21:36:58 < Steffanx> Wouldnt even know where to start
2020-07-16T21:39:10 < mawk> very easy
2020-07-16T21:39:19 < mawk> you'd try to play with the polynomial
2020-07-16T21:39:28 < mawk> 8X³+12X²+6X+1
2020-07-16T21:39:53 < mawk> if you cheat by asking wolfram alpha you figure it's 8(X+1/2)³
2020-07-16T21:40:01 < mawk> or by any other technique
2020-07-16T21:40:47 < mawk> then you try to tweak that skewed derivative to find some kind of cool invariant
2020-07-16T21:41:10 < mawk> which allows you to express (d/dt + 1/2 Id)³ as something you know
2020-07-16T21:42:03 < mawk> amazingly (exp(-t/2)f(t))' + 1/2 exp(-t/2)f(t) = exp(-t/2)f'(t)
2020-07-16T21:42:18 < mawk> you can find that by any method you like, laplace/fourier works great
2020-07-16T21:43:06 < mawk> so now you know that 8f''' + 12f'' + 6f' + 1 = exp(-t/2) ( exp(t/2) f(t) )'''
2020-07-16T21:43:14 < mawk> and the problem is over
2020-07-16T21:53:31 < Steffanx> i guess even my basic math knownledge is too basic for this :P
2020-07-16T21:54:09 < Steffanx> but as always with math, when you know what to do or know the solution its "easy"
2020-07-16T21:56:44 < Steffanx> and you have to know math to understand if you actually proved aything now mawk. ;)

2020-07-16T22:18:48 < mawk> that means if a function has 2 zeroes, then its derivative has 1 zero
2020-07-16T22:18:52 < mawk> so if f has 5, f''' has 2
2020-07-16T22:20:54 < mawk> you're convinced Steffanx right
2020-07-16T22:20:59 < mawk> it's called Rolle's theorem

2020-07-16T22:37:46 < mawk> french guy
2020-07-16T22:37:50 < mawk> yeah but you get the picture at least
2020-07-16T22:37:59 < mawk> between the two zeroes, there must be a place where the function is flat
2020-07-16T22:38:33 < mawk> after the first zero, the function is growing, before the second zero, it's decreasing
2020-07-16T22:38:43 < mawk> there must be a place between the two where it's right in between
2020-07-16T22:38:45 < mawk> aka flat
2020-07-16T22:40:30 < Steffanx> thats clear, but its more how your math proofs what you just said ;)
2020-07-16T22:42:04 < mawk> well we have 8f''' + 12f'' + 6f' + 1 = some shit × a third derivative of something involving f

2020-07-16T22:42:29 < mawk> we know shit * f has 5 zeroes, so if you apply three times Ролль theorem you know that (shit * f)''' has 2 zeroes
2020-07-16T22:42:40 < mawk> so we've proved 8f''' + 12f'' + 6f' + 1 has 2 zeroes
2020-07-16T22:42:42 < mawk> QED
2020-07-16T22:44:08 < mawk> and you can verify what I say even with your current knowledge
2020-07-16T22:44:14 < mawk> just compute (exp(t/2)f(t))'''
2020-07-16T22:44:22 < mawk> you know how to differentiate a product
2020-07-16T22:44:48 < mawk> you will find (f'''(t) + 3/2 f''(t) + 3/4 f'(t) + f(t))exp(t/2)
2020-07-16T22:45:06 < mawk> which is our thing, if you multiply that by 8
2020-07-16T22:45:09 < mawk> double QED
2020-07-16T22:49:14 < zyp> mawk, tan() disagrees
2020-07-16T22:49:24 < mawk> :(
2020-07-16T22:49:28 < mawk> it needs to be continuous
2020-07-16T22:49:33 < mawk> but shhhh
2020-07-16T22:49:36 < mawk> don't confuse my boy Steffanx 
2020-07-16T22:49:47 < mawk> tan() does not exist, it's a social construct
2020-07-16T22:52:35 < mawk> I found the problem here: https://sites.math.northwestern.edu/~mlerma/problem_solving/putnam/easy_putnam_problems.pdf
2020-07-16T22:52:41 < mawk> see it says "easy problems" I wasn't lying
2020-07-16T22:55:09 < Guest89629> there's few things as conescending as how the word "trivial" is used in math
2020-07-16T22:59:12 < Steffanx> Im sure if i put some effort into it i would understand what you did, mawk
2020-07-16T22:59:51 < Steffanx> But ... coming up with such solution is way over my head
2020-07-16T23:01:51 < Steffanx> Its always the case for me. The "how the fuck did you come up with this solution" 
2020-07-16T23:07:02 < mawk> well I'm exactly like this too Steffanx 
2020-07-16T23:07:09 < mawk> it's just that here I tried things out, it worked
2020-07-16T23:07:59 < mawk> I looked at 8X³+12X²+6X+1, I thought "maybe it has multiple roots", so I differentiated it, 24X²+24X+6, then you see that delta = 0 so this has a double root, compute it, it's 1/2, then try to see what's the third root of the polynomial I started with, 1/2 as well
2020-07-16T23:08:05 < mawk> so 8X³+12X²+6X+1 = 8(X + 1/2)³
2020-07-16T23:08:07 < mawk> as simple as that
2020-07-16T23:08:37 < mawk> -1/2 not 1/2 sorry, whatever
2020-07-16T23:09:45 < mawk> so there's no magic trick here
2020-07-16T23:09:54 < mawk> I hate magic tricks, I only like constructive proofs
2020-07-16T23:10:09 < mawk> where you explicitely construct the object without having something out of a hat
2020-07-16T23:12:34 < zyp> I like the euler's identity
2020-07-16T23:13:22 < mawk> cos(x)+isin(x) = exp(ix) ?
2020-07-16T23:13:26 < mawk> or the exp(ipi)+1 = 0
2020-07-16T23:13:52 < zyp> yes
2020-07-16T23:15:38 < Steffanx> yes
2020-07-16T23:15:59 < zyp> the power series proof is nice
2020-07-16T23:17:00 < zyp> I remember my teacher was talking about a bunch of weird stuff, and then I had an aha moment when I saw how everything fit together
2020-07-16T23:18:00 < mawk> hmm is there an alternate proof without the power series
2020-07-16T23:18:02 < mawk> I wonder
2020-07-16T23:18:08 < mawk> maybe using MaTrIcEs
2020-07-16T23:19:13 < zyp> https://en.wikipedia.org/wiki/Trigonometric_functions#Relationship_to_exponential_function_(Euler's_formula) <- there's this, which I haven't really tried understanding

2020-07-16T23:20:32 < mawk> cos(x) and sin(x) as exp(ix)
2020-07-16T23:20:55 < mawk> but I mean a proof of cos(x)+isin(x) = exp(ix), or at least a proof of exp(ipi)+1 = 0
2020-07-16T23:20:59 < mawk> without power series
2020-07-16T23:21:07 < mawk> I think I can cook up something with matrices

2020-07-17T00:42:30 < mawk> hm
2020-07-17T00:42:32 < mawk> maybe
2020-07-17T00:42:41 < mawk> with matrices maybe there's a simple argument also
2020-07-17T00:42:52 < mawk> we consider J = [[0, -1], [1, 0]] the analog of the complex i
2020-07-17T00:43:01 < mawk> we have J² = -1, all well all good
2020-07-17T00:43:17 < mawk> J is antisymetric, we have J^T = -J; so exp(aJ) is orthonormal
2020-07-17T00:43:25 < mawk> so exp(aJ) is a rotation matrix
2020-07-17T00:44:20 < mawk> and quite obvious then that exp(aJ) = [[cos(a), -sin(a)], [sin(a), cos(a)]]
2020-07-17T00:44:37 < mawk> we take a = π to finish the proof
2020-07-17T00:44:39 < Steffanx> Will you become a math teacher soon mawk?
2020-07-17T00:45:05 < mawk> so exp(Jπ)+1 = 0, are you satisfied with my i-less proof that exp(iπ)+1 = 0 zyp ?
2020-07-17T00:45:10 < mawk> no Steffanx I don't know enough
2020-07-17T00:46:19 < Steffanx> More than enough for high scho
2020-07-17T00:46:21 < Steffanx> Ol
2020-07-17T00:47:12 < mawk> :(
2020-07-17T00:47:57 < mawk> do you agree with the beauty of my proof Guest1193 ?
2020-07-17T00:47:59 < mawk> with matrices
2020-07-17T00:48:55 < Guest1193> the only step I don't know is orthonormal being equivalent of a rotation
2020-07-17T00:48:56 < Guest1193> rest works
2020-07-17T00:49:37 < mawk> hmm well it's something I proved in class, the orthonormal matrices are the rotation matrices
2020-07-17T00:55:12 < mawk> and we can just make an identification anyway
2020-07-17T00:56:02 < mawk> in 2×2
2020-07-17T01:01:49 < Steffanx> More importantly: did you buy pepernoten yet, mawk?
2020-07-17T01:02:01 < mawk> why would I do that
2020-07-17T01:02:03 < mawk> :(

2020-07-17T03:11:38 < LoneElf> Heya folks. I'm running into an interesting issue. I'm using openocd+gdb on an STM32... I issue a "reset halt" command to openocd via telnet, and the connect with GDB. I'm able to set a breakpoint in main() (right at the beginning), and when I hit continue, it breaks at the breakpoint... But it seems that I'm unable to step aferwords... Every time I issue the step command it just kinda hangs out at the same breakpoint. Anybody 
2020-07-17T03:11:38 < LoneElf> ever seen this?

2020-07-17T05:50:02 < Laurenceb> radicalizing platforms like 4chan (and later 8kun) certainly all played a role 
2020-07-17T05:51:04 < Laurenceb> its all highly problematic, I'm literally shaking 
2020-07-17T06:02:12 < scrts> gents, do you even use Low Layer drivers instead of HAL?
2020-07-17T06:02:29 < dongs> they're both ugly as fuck syntax so I use neither
2020-07-17T06:03:38 < scrts> aaaaand you do what? write register modifications yourself?
2020-07-17T06:03:59 < dongs> nah stdperhiph tho I should prolly migrate to some opensores shit that is acutally pleasing to look at
2020-07-17T06:05:03 < dongs> I only do registers when proof of concept works with high level api and I need ot faster
2020-07-17T06:05:19 < dongs> like switching SPI 8>16bit mode would be too much wank with default constructs
2020-07-17T06:05:29 < dongs> but its like 3 register writes manually
2020-07-17T06:06:07 < scrts> so anyone who is not pro @ stm32 would struggle reading your code for a month? :)
2020-07-17T06:07:55 < dongs> um
2020-07-17T06:07:59 < dongs> it would be commented
2020-07-17T06:08:07 < dongs> i dont write shit like zyp does
2020-07-17T06:11:26 < dongs> actually looks like he got rid of a lot of random numbers from laks, haha
2020-07-17T06:11:36 < dongs> i see proper bitshifts and even some comments as to waht shit does
2020-07-17T06:12:11 < scrts> HAL seems to be easy to use
2020-07-17T06:12:37 < scrts> it's just that there's always 100 pages forum threads debating which is better once you start..

2020-07-17T12:09:20 < dongs> so they just told me "use that shit as a reference and youll be ok"
2020-07-17T12:10:46 < veverak> lol
2020-07-17T12:10:48 < veverak> LOOOOL
2020-07-17T12:26:58 < zyp> well, yeah, that works
2020-07-17T12:27:28 < zyp> run a timer from the 10mhz, use that timer to time the packet intervals
2020-07-17T12:28:59 < zyp> works until you get a corrupted/dropped ethernet packet at least 
2020-07-17T12:35:28 < Steffanx> That wont happen. Perfect world.

2020-07-17T12:40:29 < t4nk_freenode> :b
2020-07-17T12:40:30 < mawk> lol what
2020-07-17T12:40:38 < mawk> where did racism come from this time
2020-07-17T12:40:46 < Steffanx> Yo momma
2020-07-17T12:40:56 < t4nk_freenode> don't even realise huh? ehehe
2020-07-17T12:41:02 < mawk> yahwe comes from middle-east
2020-07-17T12:41:30 < mawk> I do realize that you need to put off your racism goggles
2020-07-17T12:41:44 < Steffanx> Ask opper opper izua mawk. Or dekar
2020-07-17T12:42:02 < mawk> who's that

2020-07-17T12:42:44 < t4nk_freenode> put off - "hold back to a later time" .... so ... is in about 30mins ok for you then, mawk
2020-07-17T12:42:45 < t4nk_freenode> ?
2020-07-17T12:42:48 < t4nk_freenode> lol
2020-07-17T12:42:52 < Steffanx> Yes. Hes romanian. Nuff said right?
2020-07-17T12:42:58 < mawk> you're talking nonsense t4nk_freenode 
2020-07-17T12:43:02 < t4nk_freenode> euh

2020-07-17T12:43:12 < Steffanx> Alive
2020-07-17T12:43:14 < mawk> you should abstain from making comments in the future if you're not sure of what you say
2020-07-17T12:43:15 < t4nk_freenode> I really don't think you are accurate there either
2020-07-17T12:43:35 < t4nk_freenode> mawk.. don't go there man.. you're not really making sense here
2020-07-17T12:44:03 < Steffanx> Lol. Lets confuse each other
2020-07-17T12:44:06 < mawk> well please describe to me in simple terms how saying the christian god originated in middle-east is racism
2020-07-17T12:44:16 < Steffanx> Trollled
2020-07-17T12:44:27 < Steffanx> Good job t4nk_freenode 
2020-07-17T12:44:32 < t4nk_freenode> I got better things to do mawk ;)
2020-07-17T12:44:34 < Steffanx> You levelled up
2020-07-17T12:44:39 < t4nk_freenode> lol, thnx stef :))
2020-07-17T12:44:53 < mawk> yeah you need to take your money collection from the ADL now
2020-07-17T12:45:10 < t4nk_freenode> mawk, please, stop. you are demonstrating ignorance
2020-07-17T12:45:16 < mawk> lol
2020-07-17T12:45:19 < mawk> why should I stop ?
2020-07-17T12:45:27 < t4nk_freenode> then just go on if you like
2020-07-17T12:45:29 < mawk> throwing racism accusation around isn't "trolling"
2020-07-17T12:45:31 < mawk> mister pedophile
2020-07-17T12:45:36 < t4nk_freenode> I'm out in any case, leaving my proof
2020-07-17T12:45:40 < Steffanx> Be aware that after a few years of this you will become a grumpy racist, t4nk_freenode 
2020-07-17T12:45:50 < Steffanx> Dont forget i warned you
2020-07-17T12:45:58 < mawk> how did you feel when you raped that 5 years old t4nk_freenode ???
2020-07-17T12:46:10 < t4nk_freenode> lol... Steffanx ... it is a bit eerie... but I think you could be right
2020-07-17T12:46:18 < Steffanx> Come on mawk.
2020-07-17T12:46:33 < t4nk_freenode> yeah, real class act
2020-07-17T12:46:35 < mawk> I'm trying the dirty accusations game too
2020-07-17T12:46:40 < mawk> it's funny I agree
2020-07-17T12:47:02 < mawk> what you're not happy ? it's just trolling
2020-07-17T12:47:12 < mawk> how many stitching points did she have ?
2020-07-17T12:47:45 < Steffanx> Someone doesnt know when to stop sadly -_-
2020-07-17T12:48:00 < mawk> I'm a social animal, I do mimetism
2020-07-17T12:48:14 < mawk> I see a funny game, I play it
2020-07-17T12:48:53 < Steffanx> I dont think you think it was funny. Such sarcadm
2020-07-17T12:48:56 < Steffanx> Sarcasm
2020-07-17T12:49:07 < mawk> well it seems funny to both of you, so it must be
2020-07-17T12:49:17 < mawk> who am I to judge other persons sentiments
2020-07-17T12:49:29 < Steffanx> Youre mawk.
2020-07-17T12:49:49 < Steffanx> More importantly: hows the php going today mawk?
2020-07-17T12:50:04 < Steffanx> I can imagine thats why you act like this today
2020-07-17T12:50:17 < mawk> lol
2020-07-17T12:50:54 < mawk> you see racism accusation is a Gödelian black hole, you cannot refute it
2020-07-17T12:51:05 < mawk> and I'm not doing php anymore
2020-07-17T12:51:09 < mawk> I found a slav slave to do it
2020-07-17T12:53:48 < mawk> oh I know, t4nk_freenode was just being homophobic
2020-07-17T12:54:04 < mawk> I am silly, it was obvious
2020-07-17T12:54:38 < Steffanx> You're still having a hard time uh?
2020-07-17T12:54:46 < mawk> now that's an easy accusation to depart from, you just have to exhibe your one gay friend
2020-07-17T12:54:53 < Steffanx> Time for some relaxing math.
2020-07-17T12:55:03 < mawk> hard time of what
2020-07-17T12:55:08 < mawk> people lose their jobs for accusations like this lol
2020-07-17T12:55:19 < mawk> you're living in a cave
2020-07-17T12:56:14 < Steffanx> Or maybe its time for your daily "substraction" (just translate it to dutch and.. then think of what it actually is). Lolol
2020-07-17T12:58:51 < mawk> don't talk about this here, it might arouse t4nk_freenode 
2020-07-17T13:00:41 < mawk> but I heard chemical castration does wonders, after that they almost become normal human beings
2020-07-17T13:00:50 < mawk> that's what they used to do to soldiers going to the front

2020-07-17T13:04:00 < Guest1193> I wonder if it was mawk the passenger the taxi driver was talking about
2020-07-17T13:20:16 < Steffanx> Haha, for sure.
2020-07-17T13:23:56 < Steffanx> So tell us, whats the history behind this mr mawk?
2020-07-17T13:25:59 < Steffanx> And while you're at it. Why does tennisnhave have this weird score system?
2020-07-17T13:52:26 < Mangy_Dog> lol guest

2020-07-17T14:51:17 < t4nk_freenode> I was having another look at timers yesterday, but got seriously confused.. using f407vet6, I want(ed) to have a 40Mhz signal. Or at least: shouldn't it be possible to have a timer interrupt at that interval? I'd like to have a callback and count up to 500 for example, and flip an i/o. So I set my system clock to 160MHz, and use timer1. I thought I could use HAL_TIM_PeriodElapsedCallback, but it does not yield the desired 
2020-07-17T14:51:18 < t4nk_freenode> results
2020-07-17T14:51:32 < dongs> at 40MHz?
2020-07-17T14:51:34 < t4nk_freenode> is it at all possible? and alternatively
2020-07-17T14:51:50 < dongs> you can *output* 40MHz clock on a timer, but there's no way toure gonna get 40mhz IRQ going
2020-07-17T14:51:53 < dongs> doing anything useful
2020-07-17T14:52:27 < t4nk_freenode> I should be able to generat a 40MHz signal with an f103c8, right?
2020-07-17T14:52:27 < dongs> > to have a callback and count up to 500 for example, and flip an i/o.
2020-07-17T14:52:34 < dongs> how doyou expect that to work wehn your CPU is at 168mhz
2020-07-17T14:52:43 < t4nk_freenode> and shouldn't I then be able to capture that signal with f407vet6?
2020-07-17T14:53:30 < dongs> you can output and input capture 40mhz but don't expect to do anything other than counting pulses with hardware
2020-07-17T14:53:45 < t4nk_freenode> no, dongs my sysclock is set to 140MHz
2020-07-17T14:53:49 < t4nk_freenode> euh
2020-07-17T14:53:51 < t4nk_freenode> 160MHz
2020-07-17T14:54:12 < t4nk_freenode> so the prescaler should be 4, and get 40MHz, that's my reasoning?
2020-07-17T14:54:53 < dongs> no
2020-07-17T14:55:00 < dongs> timers are on APB1/APB2/AHB/whatever
2020-07-17T14:55:05 < dongs> that alone runs at sysclk/2 or /4
2020-07-17T14:55:07 < t4nk_freenode> it is... but you mean I am wrong :)
2020-07-17T14:55:37 < dongs> look at the clock tree and how you configured bus clocks
2020-07-17T14:55:40 < dongs> then look what bus your timer is at
2020-07-17T14:55:51 < dongs> then look at refman to see if it runs at that bus speed or bus speed /2
2020-07-17T14:55:57 < dongs> or bus speed * 2
2020-07-17T14:56:15 < dongs> then youll know the max clock it will run at BUT
2020-07-17T14:56:30 < dongs> if you're expecting to have an IRQ firing from 40Mhz input then forget it
2020-07-17T14:56:48 < t4nk_freenode> I'm using cubeide, and the clock configuration says the APB2 timer clocks run at 160MHz
2020-07-17T14:57:05 < t4nk_freenode> and I read in the datasheet that i/o should go upt to 80MHz indeed, so a lot less
2020-07-17T14:57:14 < dongs> and?
2020-07-17T14:58:36 < t4nk_freenode> and so the timer clock should be able to have me flip an i/o at 40MHz resolution? not necessarily continuous at 40MHz though
2020-07-17T14:59:13 < t4nk_freenode> but I need the resolution.. ehm, perhaps it helps if I mention that I'd like to experiment with generating a vga signal
2020-07-17T14:59:15 < t4nk_freenode> ;)
2020-07-17T14:59:19 < dongs> did you configure GPIO drive at 50 or 100MHz
2020-07-17T14:59:24 < dongs> for the timer output
2020-07-17T15:00:21 < t4nk_freenode>   GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH; is what I have in my init code
2020-07-17T15:01:30 < t4nk_freenode> I have some old asm code I wrote for pic18F, where I generated vga in a loop
2020-07-17T15:02:00 < t4nk_freenode> this time I thought I'd try it in c, for mental rest ;) and with the use of timers, for more rest, or so I thought
2020-07-17T15:03:03 < dongs> configure timer to output solid 40mhz first
2020-07-17T15:03:21 < dongs> once that works, fuck with period/timebase/whatever in a loop to adjust shit
2020-07-17T15:03:50 < dongs> https://github.com/abelykh0/VGA-demo-on-bluepill thertes obviousl people who have done it
2020-07-17T15:04:39 < t4nk_freenode> you mentioned refman
2020-07-17T15:04:41 < dongs> Lol fucking asm
2020-07-17T15:04:45 < t4nk_freenode> need to look up what that is
2020-07-17T15:04:47 < dongs> yeah reference manual
2020-07-17T15:04:49 < t4nk_freenode> lol
2020-07-17T15:04:52 < t4nk_freenode> heheh
2020-07-17T15:04:59 < t4nk_freenode> in gentoo we have repoman ;)
2020-07-17T15:05:18 < dongs> RM0090 in case of F407
2020-07-17T15:12:00 < t4nk_freenode> thnx for your input, dongs, I got some chores but I'll be rivisiting in a bit
2020-07-17T15:12:45 < t4nk_freenode> heh, I got pic18f doing pretty much what I want @12MIPS... I was hoping to have something better with this stm32
2020-07-17T15:12:46 < t4nk_freenode> ;)
2020-07-17T15:13:33 < t4nk_freenode> are there idiots writing pure asm for stm32? I'm thinking of becoming one.
2020-07-17T15:21:01 < qyx> are you going to use asm to bitbang vga?
2020-07-17T15:21:46 < t4nk_freenode> already have
2020-07-17T15:22:24 < qyx> why
2020-07-17T15:22:45 < t4nk_freenode> because I could, basically ;) for fun
2020-07-17T15:23:25 < t4nk_freenode> but pic18f is severely limited, so I wondered what I could do with f407
2020-07-17T15:23:28 < qyx> theres the DMA
2020-07-17T15:23:51 < qyx> you can pregenerate the whole frame and output it without any code at all
2020-07-17T15:23:56 < qyx> via gpio
2020-07-17T15:24:06 < qyx> or using spi
2020-07-17T15:24:45 < t4nk_freenode> via gpio sounds good

2020-07-17T16:30:02 < zyp> qyx, or LTDC
2020-07-17T16:30:56 < zyp> LTDC outputs vsync, hsync and parallel rgb, so you're just a DAC away from VGA
2020-07-17T16:43:16 < qyx> ltdc must be something new
2020-07-17T16:51:13 < zyp> introduced in f429 IIRC
2020-07-17T17:06:07 < t4nk_freenode> yes, that ltdc sounds good, zyp .. too bad I only got f407 which doesn't have that
2020-07-17T17:07:16 < t4nk_freenode> where did I read that timers can be configured anywhere from 1 nanosecond to several minutes...?
2020-07-17T17:08:34 < t4nk_freenode> without talking about vga signals or whatever: if dong says I can't even count at 40MHz.. then that would be extremely saddening methinks
2020-07-17T17:09:16 < zyp> who says you can't count at 40MHz?
2020-07-17T17:09:31 < zyp> or what do you mean, count by cpu?
2020-07-17T17:10:06 < t4nk_freenode> <dongs> you can *output* 40MHz clock on a timer, but there's no way toure gonna get 40mhz IRQ going
2020-07-17T17:10:44 < t4nk_freenode> in the interrupt, if I have a counter, counting from 0 to 100 and then resetting.... how fast could that interrupt for me?
2020-07-17T17:13:00 < t4nk_freenode> I figured that if the apb2 timer clock runs at 160MHz(set in my case) ... then having such a loop... oughtta be trivial
2020-07-17T17:13:32 < zyp> remember that when the cpu enters and leaves interrupt handlers, it needs to save and restore register contents
2020-07-17T17:13:50 < t4nk_freenode> yes, so around 4 instructions overhead there is
2020-07-17T17:13:54 < t4nk_freenode> or 3
2020-07-17T17:14:10 < zyp> how do you figure?
2020-07-17T17:14:42 < t4nk_freenode> mmmm yea, well, maybe not quite indeed ;)
2020-07-17T17:14:45 < zyp> you've got a 32-bit wide bus, so you'll need at least one cycle per register saved and restored
2020-07-17T17:15:06 < zyp> and you're saving and restoring something like ten
2020-07-17T17:19:09 < zyp> to be fair, if you're handling interrupts continously then the cpu will skip restoring and saving and just tail chain the handlers, but then you can't do anything else and at that point it'd be better to just run a loop and poll the timer
2020-07-17T17:20:12 < zyp> but still, using a timer to count to four is pointless :)
2020-07-17T17:23:44 < zyp> also, the problem with writing assembly and relying on cycle timing like you can on a slower mcu is that on a highend mcu it's not fully deterministic
2020-07-17T17:24:54 < t4nk_freenode> I could perhaps setup several timers, or change one on the fly, to (only as an example) set the course delays and flip an i/o .. so 20us, 1us, 3.2us etc
2020-07-17T17:25:23 < zyp> IIRC the stm32f407 flash can't run faster than 30 MHz, so to compensate it's 128 bits wide, with a cache in between that and the cpu
2020-07-17T17:25:36 < t4nk_freenode> and then try to grab the i/o's by their proverbials to try and hit that 40MHz pixel clock
2020-07-17T17:26:25 < zyp> so when you get a cache miss, you might have an instruction taking a few cycles extra just to load it from the flash
2020-07-17T17:26:49 < qyx> multiple timers with multiple interrupts are not going to help you
2020-07-17T17:27:12 < t4nk_freenode> yea, I just read a comment saying 'asm on an 8-bitter is less fiddly'
2020-07-17T17:27:17 < zyp> a mcu with a cpu that can't run faster than the memories it's hooked up to would therefore naturally have much more deterministic cycle timing
2020-07-17T17:27:56 < zyp> idk, IMO writing any code that relies on cycle timing is fiddly
2020-07-17T17:28:22 < qyx> don't you like bitbanged usb?
2020-07-17T17:28:30 < zyp> not bitbanging shit and instead relying on proper peripherals is much less fiddly :)
2020-07-17T17:28:41 < t4nk_freenode> ehr... lol.. I got my own pic usb stack in asm too :)
2020-07-17T17:28:46 < t4nk_freenode> works like a charm
2020-07-17T17:28:50 < zyp> and if you're not happy with that, switch to fpgas where you can have all the deterministic timing you want

2020-07-17T17:30:38 < zyp> I haven't used the LTDC myself, but from what I understand you just put a framebuffer somewhere in ram, give it a pointer to that, and it takes care of the rest
2020-07-17T17:30:56 < zyp> then all you need to care about is modifying the ram contents
2020-07-17T17:31:41 < t4nk_freenode> yes, it sounds nice. (though I'm really trying to get an understanding of course, not getting some job done without hassle)
2020-07-17T17:32:10 < t4nk_freenode> but had I had such a port.. I'd certainly try it out
2020-07-17T17:33:19 < t4nk_freenode> maybe you're also right about the fpga's, been wanting to buy one for a long time now. don't know if there's a cheap-ish board available
2020-07-17T17:35:00 < zyp> ice40 and ecp5 have nice open toolchains

2020-07-17T21:46:03 < zyp> first hit on google is a module based on nrf52 + mcp25625
2020-07-17T21:47:54 < zyp> stm32wb plus a can controller might also be good
2020-07-17T21:48:45 < zyp> dualcore is tempting, probably easier to keep shit from stepping on each other
2020-07-17T22:02:52 < Steffanx> nrf doesnt do CAN either?
2020-07-17T22:03:09 < zyp> wouldn't expect it to
2020-07-17T22:03:21 < Steffanx> Im also a bit disappointed how limited ST STspin mcus are. i recall they didnt have CAN either, which is sad.

2020-07-19T05:13:21 < R2COM> zyp looked at your scons file for stm32 builds and decided to make chopped version for my win10 environment
2020-07-19T05:13:40 < R2COM> zyp it turns out that maybe it worked for you (linux? mac?) but for me running it as is caused tons of problems
2020-07-19T05:13:49 < R2COM> i guess it had to do with default environment etc
2020-07-19T05:14:05 < R2COM> so i made a compact version (no selection between families, just one device)
2020-07-19T05:14:07 < R2COM> https://paste.ofcode.org/iy4Fvc3K385SVdpTkxnjPT

2020-07-19T10:53:27 < zyp> scons autoprobes for toolchains, so you might get problems on windows if you have msvc installed
2020-07-19T10:53:43 < zyp> the solution is telling explicitly that you are building with a gcc-style toolchain
2020-07-19T10:54:14 < zyp> otherwise it might try running msvc-style flags with your arm-gcc
2020-07-19T10:55:25 < zyp> that's what your line 5 does, I see

2020-07-19T15:38:20 < zyp> I saw some altium spam today
2020-07-19T15:38:36 < zyp> $250/mo for a time limited license, about three times that for a perpetual one
2020-07-19T15:39:20 < jadew> so 6-7k for the perpetual one?
2020-07-19T15:39:34 < zyp> 7-8k
2020-07-19T15:39:40 < zyp> or something
2020-07-19T15:39:54 < jadew> I'll stick to kicad
2020-07-19T15:40:03 < zyp> $8890 or 12x$745
2020-07-19T15:40:26 < zyp> but then again I assume renewal of the latter is cheaper
2020-07-19T15:40:48 < jadew> I haven't used Altium in years - has it improved? is it worth the money?
2020-07-19T15:41:13 < zyp> dunno, my license is for AD15
2020-07-19T15:42:16 < jadew> I'd pay maybe 500 for it, more than that doesn't really make sense for me
2020-07-19T15:43:05 < jadew> and I'd never consider a non-perpetual license
2020-07-19T15:43:40 < zyp> same
2020-07-19T15:43:50 < Steffanx> isnt that what you did for fusion360?
2020-07-19T15:44:04 < zyp> I mean, I still use AD15, couldn't do that if it weren't perpetual
2020-07-19T15:44:36 < jadew> Steffanx, close, but with fusion I can still use the results/export the parts if I decide not to renew
2020-07-19T15:44:53 < Steffanx> ah ok
2020-07-19T15:45:02 < zyp> pretty sure altium lets you do that too
2020-07-19T15:45:16 < zyp> IIRC not having an active license only prevents you from editing and saving
2020-07-19T15:45:48 < jadew> can you export to a different CAD?
2020-07-19T15:46:24 < zyp> dunno
2020-07-19T15:46:48 < jadew> I think that's where the difference is, 3d files are a bit more portable than schematics/pcb design
2020-07-19T15:47:29 < zyp> oh, I thought you meant whether you're allowed to, not whether exporters exist
2020-07-19T15:48:38 < zyp> I assume there's ways to move designs between all the big PCB packages, but I don't know what sort of licensing restrictions there are on that
2020-07-19T15:49:42 < zyp> I also assume format differences makes it kinda ugly
2020-07-19T15:49:44 < zyp> hmm
2020-07-19T15:50:00 < zyp> actually, I might have worked with an imported design or two before
2020-07-19T15:51:14 < zyp> previous job had me modify some designs, I suspect they were imported from orcad or something
2020-07-19T16:23:21 < dongs> AD support, once expired, just prevents you from access to the live portal and updates.
2020-07-19T16:25:02 < zyp> if you have a perpetual license and not the cheaper kind of time-limited licenses
2020-07-19T16:25:14 < zyp> they apparently offer both now

2020-07-19T17:31:14 < zyp> looking at the design, I'd probably attempt putting leds on the back of the pcb, shining through holes

2020-07-19T22:53:12 < mawk> "this painting invites us to reflect upon the sinful nature of man" "this painting is a warning against pre-marital sex" "this painting incites us to the Dutch traditional piety and hard work"

2020-07-20T15:52:44 < Lux> my idea was to do the initalisation stuff with blocking hal methods and then do a dma transfer for periodic readout of a gyro

2020-07-20T16:38:45 < kakimir> with 10years old machine meh.. it doesn't run the gayms anyway
2020-07-20T16:41:20 < kakimir> gayms are actually problematic for virtualization
2020-07-20T16:42:45 < kakimir> anti-cheat mechanisms check underlying hardware for signs of virtualization

2020-07-20T22:43:28 < Steffanx> lol my russian gamer friends dont understand my question. To annoy them i say "da da" all the time, and suddenly i realized its the sound a baby makes.
2020-07-20T22:43:45 < Steffanx> but in russian its obviously not that
2020-07-20T22:44:23 < zyp> have you ever actually interacted with a baby? they make tons of sounds
2020-07-20T22:44:44 < Steffanx> yes, but im almost sure if you ask a dutch to imitate a baby he/she would say something like "da da" 
2020-07-20T22:45:16 < PaulFertser> Steffanx: probably ah-goo
2020-07-20T22:45:21 < Steffanx> its like ask what sound cat makes "meoow meoow" 
2020-07-20T22:48:13 < upgrdman> if you want an integer number of divisions between 0 and 255, you can use a number where someInt*n = 256. what's the word for that kind of number. not "multiple" but ...?
2020-07-20T22:48:53 < Ultrasauce> factor?
2020-07-20T22:49:02 < upgrdman> yes! thx
2020-07-20T22:50:00 < Steffanx> hah ok PaulFertser ty :)
2020-07-20T22:51:07 < PaulFertser> Steffanx: but they're supposed to make it more connected, without any pause between ah and goo, and goo sounds pretty short, like guh
2020-07-20T22:51:12 < Steffanx> if its just a variable, "upgrdmanMagicNumber"  would work too, upgrdman :P
2020-07-20T22:51:37 < upgrdman> i see that Steffanx likes to write maintainable code ;)
2020-07-20T22:53:20 < Steffanx> is it open sores?

2020-07-21T14:31:25 < Steffanx> Whos bullying you this time mawk?
2020-07-21T14:32:51 < mawk> everyone
2020-07-21T14:32:54 < mawk> but mostly albert heijn
2020-07-21T14:32:57 < mawk> nobody wants my visa card
2020-07-21T14:33:01 < mawk> they say "it's a credit card"
2020-07-21T14:33:09 < mawk> I say "no look, it's written visa debit"
2020-07-21T14:33:24 < mawk> then their brain freeze, and they say "yeah we still cannot take it sorry, also it's corona times so no cash for you"
2020-07-21T14:33:26 < mawk> and they lose a sale
2020-07-21T14:34:02 < mawk> also I want to use the ideal shit since everyone forces me to use that
2020-07-21T14:38:28 < PaulFertser> Why do they even care if it's credit or not? Visa is visa, right?
2020-07-21T14:43:20 < zyp> not necessarily, could be a combined card
2020-07-21T14:44:31 < zyp> e.g. in norway debit cards are usually combined bax/visa and some stores only accept bax, and bax is debit only
2020-07-21T14:46:31 < zyp> and I've ran into the same issue in e.g. denmark, where their cards are combined dankort/visa, and some stores only accept dankort
2020-07-21T14:59:04 < Steffanx> Its nothing personal mawk. We just hate french ;)

2020-07-21T15:09:56 < mawk> my card is 100% a debit card (because I was too much under 0€ so the state forced my bank to disable my credit card)
2020-07-21T15:10:14 < mawk> it's just visa, and dutch store-owners have a physical aversion of "credit" because of their protestant religious background or something
2020-07-21T15:10:25 < mawk> so if it's not the maestro card, it's a credit card for them
2020-07-21T15:11:16 < mawk> also they care if it's credit because they don't like the delayed cash-in system PaulFertser 
2020-07-21T15:11:42 < mawk> with a credit card, every night at midnight the transaction is made; this incurs fees for them and also makes it possible for the customer to cancel the transaction under specific circumstances
2020-07-21T15:12:17 < mawk> but that's all bs claims, for the fees the EU unifiormized it all and it's now very low, also they can charge the fee to the customer if they like, and for the cancellation it happens very rarely as you usually need to fill a complaint at the police for the bank to cancel something
2020-07-21T15:13:08 < zyp> are you sure they're not just using maestro instead of visa?
2020-07-21T15:13:31 < mawk> well yes they're all using maestro instead of visa
2020-07-21T15:13:34 < mawk> maestro is the only thing they accept
2020-07-21T15:13:46 < zyp> same thing as bax/dankort then
2020-07-21T15:14:06 < mawk> but they would also reject a mastercard debit card, which is the same company as maestro and virtually the same thing; they want specifically maestro
2020-07-21T15:14:30 < zyp> well, duh
2020-07-21T15:14:58 < Steffanx> Im not even sure.. can they even take it in any way mawk?
2020-07-21T15:16:24 < mawk> take what
2020-07-21T15:16:43 < mawk> it's just a configuration switch in the card terminal to change
2020-07-21T15:16:49 < mawk> they're just too afraid to do it
2020-07-21T15:17:15 < Steffanx> Im not even sure they are too afraid
2020-07-21T15:17:24 < Steffanx> They probably dont give a damn
2020-07-21T15:17:31 < zyp> I guess it depends on the subscription they have with the payment provider
2020-07-21T15:17:48 < mawk> Steffanx: they probably lose millions € of sales to annoyed tourists
2020-07-21T15:17:54 < zyp> the reason the other shit even exists is because it's cheaper than visa
2020-07-21T15:18:08 < mawk> I'd be happy to pay the extra fee
2020-07-21T15:18:12 < mawk> some stores do that here

2020-07-21T15:22:24 < mawk> p
2020-07-21T15:23:13 < zyp> speaking of, I can't remember any dutch stores not accepting my norwegian visa
2020-07-21T15:23:23 < zyp> was an issue a couple of places in germany though
2020-07-21T15:23:36 < effractur> depends on where you are
2020-07-21T15:23:44 < effractur> touristy stuff will accept credit and debit
2020-07-21T15:23:49 < effractur> otherwise only vay/meastro
2020-07-21T15:23:52 < effractur> vpay*
2020-07-21T15:24:50 < PaulFertser> So does maestro have debit cards for which payments are processed right away?
2020-07-21T15:24:50 < Steffanx> So which dutch bank mr mawk?
2020-07-21T15:24:51 < effractur> reason is that vpay/meastro goes to the dutch clearinghouse vs the mastercard/vpay clearing house because they speak also a dutch only protocol
2020-07-21T15:25:12 < effractur> so the fee is really low for shops for the meastro/vpay cards
2020-07-21T15:25:24 < effractur> PaulFertser: yes but also mastercard cards that to that
2020-07-21T15:25:30 < effractur> it is just the protocol that the card speaks
2020-07-21T15:25:57 < mawk> visa debit also do that PaulFertser right
2020-07-21T15:26:07 < mawk> so accepting maestro only is superstition
2020-07-21T15:26:07 < effractur> vpay/meastro is <0.05 cent vs mastercard/visa 2%+fixed fee
2020-07-21T15:26:12 < zyp> but I mean
2020-07-21T15:26:21 < mawk> the bank called bunq Steffanx 
2020-07-21T15:26:22 < zyp> even Albert Heijn accepted my credit card: https://bin.jvnv.net/file/XL6to.png
2020-07-21T15:26:26 < Steffanx> Ohno mawk
2020-07-21T15:26:29 < mawk> what
2020-07-21T15:26:47 < zyp> and that's an actual credit card, not debit
2020-07-21T15:26:48 < effractur> zyp: depends where you are 
2020-07-21T15:26:48 < mawk> maybe AH in touristy places started using visa
2020-07-21T15:27:08 < zyp> dunno, don't remember which AH that was
2020-07-21T15:27:21 < zyp> probably somewhere not too far away from Steffanx 
2020-07-21T15:27:24 < effractur> AH in stations/schiphol accept visa otherwise it depends if it a franciase or a company owned AH
2020-07-21T15:27:40 < effractur> afaik do the compnay owned accept creditcards
2020-07-21T15:27:54 < mawk> kredittkort, transaksjoner, it looks like funny english
2020-07-21T15:28:19 < Steffanx> Nah they "screwed over" customers a few weeks ago, mawk. And i recall people complained a lot about their new amazing wonderful cool fancy app.
2020-07-21T15:28:27 < mawk> you don't like it Steffanx ? I already hate it, they asked me for 3 different identification means and they still think I'm a money-laundering terrorist
2020-07-21T15:28:50 < mawk> well yeah I guess they need more beta-testers
2020-07-21T15:28:53 < effractur> i just use ing +transferwise
2020-07-21T15:29:02 < mawk> as long as they don't lock up my money
2020-07-21T15:29:12 < mawk> I already lost like 400€ to fake money-laundering claims
2020-07-21T15:29:18 < Steffanx> Their free account "suddenly" became non-free and they just started to charge the fees.
2020-07-21T15:29:25 < mawk> there are valid reasons to use a fake ID, give me my money back
2020-07-21T15:29:27 < effractur> mawk: well use a proper bank 
2020-07-21T15:29:40 < effractur> not something link bunq there are known to lose money
2020-07-21T15:29:51 < Steffanx> Haha
2020-07-21T15:30:00 < mawk> I'm keeping my french bank anyway
2020-07-21T15:30:03 < mawk> this is just to pay at AH
2020-07-21T15:30:05 < effractur> i know like 5+ people who lost money with them
2020-07-21T15:30:40 < effractur> quite amazing how bad they are at the basic thing that a bank has to do
2020-07-21T15:30:45 < Steffanx> I have a german bank account for all my secret business :D
2020-07-21T15:30:50 < mawk> lol
2020-07-21T15:30:53 < mawk> which secret business ?
2020-07-21T15:30:59 < mawk> your sextoy store ?
2020-07-21T15:31:04 < Steffanx> Nah  its just for their free debit card
2020-07-21T15:31:11 < Steffanx> N26.
2020-07-21T15:31:21 < mawk> people got their money locked up as well with that
2020-07-21T15:31:28 < mawk> but it's got to do with hard anti-laundering regulation
2020-07-21T15:31:43 < mawk> make a big transfer, like 1 million €, they suddenly lock you out and ask for a ton of paperwork
2020-07-21T15:32:08 < Steffanx> Very unlikely that will happen for me
2020-07-21T15:32:20 < effractur> why would you want to put 1mil in that kind of bank
2020-07-21T15:32:26 < mawk> I guess institutions are a bit chilly when it comes to online banking so these are overzealous in their verifications
2020-07-21T15:33:00 < Steffanx> Even N26 was damn easy. 
2020-07-21T15:33:01 < mawk> it's a french guy that inherited from his father or something, he got the money on his principal N26 account
2020-07-21T15:33:04 < Steffanx> Maybe even too easy
2020-07-21T15:33:10 < mawk> I hope he got the money back
2020-07-21T15:33:46 < effractur> well just a lot of papwe work
2020-07-21T15:34:43 < Steffanx> Only thing that sucks is that the  instant payments does not work between my main bank and n26. Because the fuckers deciced to not use the same standards 
2020-07-21T15:35:04 < Steffanx> Lets invent multiple "standards"
2020-07-21T15:35:59 < mawk> yeah that thing costs me 1€ for no reason
2020-07-21T15:36:04 < effractur> main problem is that NL invented a lot of that stuff before other countries
2020-07-21T15:36:28 < Steffanx> And yet they only really started to use it quite recently effractur 
2020-07-21T15:36:50 < effractur> Steffanx: well some banks had it earlier
2020-07-21T15:36:56 < zyp> Steffanx, is this a very touristy AH? https://goo.gl/maps/dcpy79d7K2fSwaf58
2020-07-21T15:37:09 < zyp> that's the one I used my credit card at
2020-07-21T15:37:44 < mawk> it's the only shopping center of all friesland I'm sure
2020-07-21T15:37:49 < Steffanx> I dont know. Probably not. But ive never been therr
2020-07-21T15:38:04 < Steffanx> Friesland..?!
2020-07-21T15:38:09 < mawk> yes
2020-07-21T15:38:14 < mawk> north = friesland
2020-07-21T15:38:15 < Steffanx> GRONINGEN
2020-07-21T15:38:20 < mawk> it's called simplified geography
2020-07-21T15:38:31 < mawk> in france, everything down of paris is called "south"
2020-07-21T15:38:33 < Steffanx> Or Grunn. In the local dialect
2020-07-21T15:39:04 < effractur> zyp: it is near the uni that is english speaking
2020-07-21T15:39:19 < effractur> with a lot of international students
2020-07-21T15:40:15 < Steffanx> Mawk: Our dialect is the best. We have many variants of "moi" (it's "hoi" with an m)
2020-07-21T15:40:21 < Steffanx> It means hi, or bye. 
2020-07-21T15:40:28 < mawk> it's different from frysk ?
2020-07-21T15:41:04 < Steffanx> Where "moie" can be a way to express youre surprised.
2020-07-21T15:42:51 < Steffanx> Probably similar mawk
2020-07-21T15:45:48 < Steffanx> Mawk, i think you will hate us anyway. When you cooked dinner and ask a "groningen" if he/she liked it and the reply is " het kon minder " (it could be less)
2020-07-21T15:45:54 < Steffanx> Its actually a compliment
2020-07-21T15:46:01 < mawk> lol
2020-07-21T15:46:50 < Steffanx> I wonder if even effractur would understand its a compliment

2020-07-21T15:50:36 < effractur> s
2020-07-21T15:52:26 < Steffanx> Yes, but "'t kon minder" is just weird for many people. Not even close to a compliment

2020-07-21T15:54:11 < mawk> it's like "not bad" in english
2020-07-21T15:54:30 < mawk> or the reverse in french, "awesome", "great", "wonderful", all these can mean negative things depending on the context
2020-07-21T15:55:39 < Steffanx> Hah awesome 
2020-07-21T15:56:03 < mawk> so when you don't understand you node and you say "thanks"
2020-07-21T15:56:08 < mawk> it will be fine
2020-07-21T15:58:15 < Steffanx> The most annoying is how often a french one says "pardon"
2020-07-21T15:58:48 < mawk> pardon
2020-07-21T15:59:00 < mawk> you don't believe in forgiveness ??
2020-07-21T15:59:04 < mawk> where is your religious education
2020-07-21T16:01:53 < Steffanx> No i mean they just say it very often i noticed.
2020-07-21T16:04:04 < mawk> yes I know
2020-07-21T16:04:23 < mawk> but "pardon" means they prompt you to forgive them
2020-07-21T16:16:18 < Steffanx> Ofcourse i did forgive em. With well meant "OK" 
2020-07-21T16:17:35 < mawk> but "pardon" is rude
2020-07-21T16:17:44 < mawk> you're supposed to say "excuse-me"
2020-07-21T16:17:50 < mawk> "pardon" is like saying "I excuse myself"

2020-07-21T17:05:44 < catphish> okay twice as much, but still, seems a better idea
2020-07-21T17:06:43 < bitmask> theres reasons why I'm not going to do that, I will get a benchtop later on but a handheld or usb is all I want right now

2020-07-22T00:03:20 < zyp> I mean, even the smaller ecp5s are cheaper than that
2020-07-22T00:03:29 < zyp> e.g. LFE5U-25F
2020-07-22T00:03:40 < zyp> or -12F
2020-07-22T00:03:49 < qyx> the important factor here are the rise/fall times and ability to slide a sample&hold switch in time in small increments
2020-07-22T00:03:58 < qyx> (in the ps range)
2020-07-22T00:04:24 < qyx> idk if a fpga is able to do 10ps like this one
2020-07-22T00:04:37 < qyx> I considered G4 with HRTIM
2020-07-22T00:04:46 < zyp> idk either, but as far as I understand programmable delay lines are common
2020-07-22T00:04:51 < qyx> which can do 160ps iirc, which would be usable
2020-07-22T00:06:28 < qyx> 1ns is about ~10cm of RG58
2020-07-22T00:06:41 < qyx> which would give me reasonable resolution
2020-07-22T00:07:05 < qyx> besides that I don't believe I would gain anything using smaller steps
2020-07-22T00:08:17 < qyx> hm, yeah, I could trash the power hungry LVPECL stuff, use 74lvc1g14 or similar for pulse shaping
2020-07-22T00:08:27 < qyx> and delay sample&hold using STM32G4
2020-07-22T00:10:40 < zyp> hmm, ECP5 got a «DELAYF» primitive that gives you ~25ps steps
2020-07-22T00:10:47 < qyx> O_o
2020-07-22T00:10:57 < qyx> what range?
2020-07-22T00:11:00 < zyp> 128 steps
2020-07-22T00:11:41 < qyx> thats 3.2ns, but a more coarse delay could be done with a simple timer/counter
2020-07-22T00:11:42 < zyp> and I guess there might be more usable primtives too
2020-07-22T00:12:23 < zyp> it can do DDR3 and DDR3 relies on delay tuning to do «read levelling»
2020-07-22T00:12:47 < R2COM> zyp great thanks
2020-07-22T00:13:56 < zyp> ddr3 uses a fly-by topology for the control signals, so the control signals and data signals might have different lengths for each byte lane
2020-07-22T00:14:33 < qyx> hm
2020-07-22T00:14:34 < zyp> so it requires the controller to be able to tune the skew of each byte lane, which involves tunable delays
2020-07-22T00:15:38 < Steffanx> Yeah benishor

2020-07-22T23:48:33 < aandrew> ok pros
2020-07-22T23:49:15 < strata> so they implemented mandatory mask rule for outside here
2020-07-22T23:49:39 < strata> today i went and bought a 3 pack of black shoe polish to put on my face instead
2020-07-22T23:50:00 < strata> this way i won't have to wear the mask all the time, only in stores.
2020-07-22T23:50:06 < aandrew> if you want to create a cheap "programmable" current sink of something like 10-1000uA (maybe 100-1000uA) how would you do it? PWM the base of a regular odl NPN BJT or would use use a little mosfet instead
2020-07-22T23:50:31 < aandrew> I think it'd be easier to control the current into a BJT than to try to ride the linear region of a mosfet
2020-07-22T23:50:58 < Steffanx> Mawk dont you have to enable contactless payment in their app?
2020-07-22T23:51:45 < Steffanx> Or do you mean contactless with your phone?
2020-07-22T23:54:21 < Steffanx> And google says you have to pay with your card once first.

2020-07-23T00:57:41 < fluiD> I'm considering getting a team together to write the STM32 code to handle motor control for a telescope.
2020-07-23T00:58:18 < qyx> paid or opensores?
2020-07-23T00:58:26 < fluiD> paid
2020-07-23T00:59:30 < fluiD> ... I may need a software team to write the whole user interface stuff as well.
2020-07-23T00:59:55 < qyx> is the hardware done yet?
2020-07-23T01:00:25 < fluiD> Nope. Nothing has been started. I'm just doing some initial research to see what this would entail.
2020-07-23T01:01:47 < qyx> hm, you can keep me posted regarding the HW part
2020-07-23T01:02:15 < fluiD> alrighty
2020-07-23T01:10:00 < PaulFertser> fluiD: by motor control do you mean something fancy or just steppers + encoders?
2020-07-23T01:10:37 < fluiD> servo with quadrature velocity encoders and serial absolute encoders.
2020-07-23T01:12:55 < sync> which wire serial encoders?
2020-07-23T01:13:00 < sync> -wire
2020-07-23T01:17:03 < fluiD> BiSS
2020-07-23T01:17:27 < sync> egh
2020-07-23T01:17:34 < fluiD> although the actual implementation is mostly generic synchronous serial
2020-07-23T01:18:03 < sync> BiSS is ok, I just dislike it
2020-07-23T01:20:47 < sync> what kind of power is the motor?
2020-07-23T01:21:05 < fluiD> usually under 1 hp
2020-07-23T01:21:14 < fluiD> well, almost always

2020-07-23T01:27:31 < sync> well, I have the drive fitting the reqs sitting here
2020-07-23T01:31:10 < zyp> hmm
2020-07-23T01:31:52 < zyp> I hadn't heard about BiSS before, but I see it's apparently a successor to SSI
2020-07-23T01:33:12 < zyp> and I dislike SSI :p
2020-07-23T01:36:26 < _franck_> hi, I working on re a STM32 firmware. I think I have identified a create_task function. I would like to know if this pseudo prototype would fit a known OS function:
2020-07-23T01:36:35 < _franck_> create_task_FUN_08001234(char *name, void *func, 0, 1, 0x2f8, void *param, 0);
2020-07-23T01:37:13 < _franck_> it's not FreeRTOS. My goal is to identify which OS it is
2020-07-23T01:41:23 < zyp> would the 0x2f8 be the stack size to allocate?
2020-07-23T01:41:33 < zyp> strange to not see a round number
2020-07-23T01:41:36 < _franck_> zyp: I guess
2020-07-23T01:44:02 < _franck_> somtimes it finished like this: ......0,1,0x294,puVar1,6000);
2020-07-23T01:44:56 < _franck_> the last param looks like a flag
2020-07-23T01:45:12 < zyp> hmm, doesn't fit any of the RTOSes from the top of my head
2020-07-23T01:45:24 < _franck_> no, it's not an hex value
2020-07-23T01:45:35 < _franck_> zyp : ok thanks

2020-07-23T10:44:28 < Steffanx> Yes it is. Softbank would buy the world if they could.

2020-07-23T16:27:12 < zyp> which vga example?
2020-07-23T16:28:10 < t4nk_freenode> I think this one
2020-07-23T16:28:11 < t4nk_freenode> https://github.com/abelykh0/VGA-demo-on-bluepill
2020-07-23T16:29:33 < t4nk_freenode> it's not actually this project, but he got inspired by it, and so I started reading that
2020-07-23T16:30:09 < zyp> don't think I linked that one, but I linked somebody using LTDC to generate VGA
2020-07-23T16:30:44 < t4nk_freenode> ahyeah, I remember that.. lol, my immediate thoughts on that were... 'I don't think that'll do it for me'
2020-07-23T16:34:11 < t4nk_freenode> was looking for his ref... he put it this way:
2020-07-23T16:34:13 < t4nk_freenode> The STM32F427 and friends were paper-launched before I started this project, but shipped well after. They have LCD controllers. Yes, you can trick their LCD controller into doing 800x600. No, that does not sound like an interesting problem to me. ;-)

2020-07-23T19:33:59 < englishman> zyp: soyboy is someone who consumes lots of soy, and as a result, posts on twitter a lot due to the high estrogen levels caused by the soy. the theory is all modern problems stem from the high soy diet introduced in the last 20 years
2020-07-23T19:34:08 < englishman> it is true that soy makes you grow boobs tho
2020-07-23T19:34:36 < strata> it also causes males to have mood swings and capitulate the soy-generated mob mentality

2020-07-23T20:23:49 < benishor> I have two identical stm32f746 discovery boards. when I plug one of them in one of my desktop's usb port, I see it listed in lsusb output
2020-07-23T20:24:16 < benishor> when I plug the other one, the uploaded program starts running but I don't see any trace of it in lsusb output or dmesg
2020-07-23T20:24:24 < benishor> any idea?
2020-07-23T20:27:04 < t4nk_freenode> well, I think that even when the second board has non-usb software.. it would still have to show up in dmesg, if only with errors
2020-07-23T20:27:48 < t4nk_freenode> because the usb port should detect a connection
2020-07-23T20:28:18 < t4nk_freenode> unless the pins on the board are somehow remapped? I don't know if that is at all possible though
2020-07-23T20:31:15 < benishor> both boards are running the same program
2020-07-23T20:31:31 < benishor> and when I plug in the second board, there is absolutely no message whatsoever in dmesg
2020-07-23T20:31:58 < benishor> as opposed to the first one
2020-07-23T20:32:13 < benishor> could it be that the stlink uC is ded?
2020-07-23T20:32:26 < t4nk_freenode> unlikely
2020-07-23T20:32:26 < benishor> which would explain why the previously updated code still runs upon reboot
2020-07-23T20:33:54 < t4nk_freenode> there's a resistance on the usb pins, which one depends on the speed of the device
2020-07-23T20:34:05 < t4nk_freenode> this should always be the case
2020-07-23T20:34:14 < t4nk_freenode> that is how the host detects a new device
2020-07-23T20:34:53 < t4nk_freenode> so if you plug it in... the host will always think there's a new usb device, and will try to enumerate
2020-07-23T20:36:12 < benishor> what pins should show a resistance?
2020-07-23T20:36:37 < t4nk_freenode> either d+ or d-, depending on the speed
2020-07-23T20:37:18 < sync> Laurenceb: that is why you measure efficency in a jig
2020-07-23T20:37:24 < sync> but yeah, it's suprisingly difficult
2020-07-23T20:38:19 < benishor> hmm, the board gets powered by usb link
2020-07-23T20:38:28 < benishor> except there seems to be no data
2020-07-23T20:38:58 < benishor> and I excluded the OS and cable since the other board works just fine in the same configuration
2020-07-23T20:54:21 < t4nk_freenode> yeh, but what software are you using? what does the st-link report when you try to flash the board?

2020-07-23T20:57:41 < t4nk_freenode> may also be that the usb connector is faulty, the usb pins should be exposed on the headers too so you could check

2020-07-23T21:02:47 < benishor> regardless of the software I use, the good one registers itself in the list of usb devices, the other one does not 
2020-07-23T21:02:59 < benishor> so yeah, there must be something physical
2020-07-23T21:03:26 < t4nk_freenode> connect the board, and wiggle the connector on the board around (gently ;) )
2020-07-23T21:03:33 < t4nk_freenode> see if something shows up in dmesg
2020-07-23T21:07:43 < benishor> nothing shows up, however..
2020-07-23T21:07:57 < benishor> there's an rgb led next to the stlink miniusb connector
2020-07-23T21:08:06 < benishor> on the good board the led lights up in red
2020-07-23T21:08:18 < benishor> on the bad board the led links in red
2020-07-23T21:08:28 < benishor> *blinks*
2020-07-23T21:08:37 < benishor> so I take it that must be some sort of an error code
2020-07-23T21:09:16 < t4nk_freenode> might, I'm not up to speed on stm32 ;) ... but the output of the stlink is still important
2020-07-23T21:09:28 < t4nk_freenode> so you can flash the 'bad' board ok?
2020-07-23T21:09:50 < t4nk_freenode> otherwise, just upload a blinky

2020-07-23T21:16:24 < t4nk_freenode> lol, indeed, now the other page is gone too :)
2020-07-23T21:16:39 < benishor> when I try to paste something new:
2020-07-23T21:16:45 < benishor> Pastebin is currently undergoing some planned system maintenance.

2020-07-23T21:16:58 < benishor> damn timing
2020-07-23T21:17:12 < t4nk_freenode> yeah, that's life for you
2020-07-23T21:17:17 < benishor> what I meant was that stlink connects to the pc by usb
2020-07-23T21:17:35 < benishor> stlink acts as a mediator between two interfaces
2020-07-23T21:17:47 < t4nk_freenode> yeah, but that's irrelevant, unless you can't see the st-link either from time to time
2020-07-23T21:18:07 < t4nk_freenode> what you need to do is to flash the board again
2020-07-23T21:18:12 < benishor> the point here is that on the bad board I don't get to see the stlink usb interface
2020-07-23T21:18:13 < t4nk_freenode> get a blinky.hex 
2020-07-23T21:18:26 < benishor> I can't flash it since I would need stlink to flash it

2020-07-23T21:19:34 < benishor> if the rightmost connection is ded, I can't get to the flashing part
2020-07-23T21:19:46 < benishor> the stm32 discovery boards have an on-board stlink chip
2020-07-23T21:19:52 < PaulFertser> benishor: but you can connect other stlink externally
2020-07-23T21:19:55 < benishor> which makes it easy to program/debug
2020-07-23T21:20:02 < PaulFertser> benishor: from another board where stlink is working.
2020-07-23T21:20:06 < benishor> PaulFertser: I suppose so, except my stlink-v2 is still on order
2020-07-23T21:20:14 < PaulFertser> benishor: no, the one on the other disco board.
2020-07-23T21:20:19 < benishor> good point
2020-07-23T21:20:32 < benishor> but that would only manage to flash the "bad" board
2020-07-23T21:20:51 < benishor> I'd like to know whatever happened to the stlink on the bad board and whether I can fix it somehow
2020-07-23T21:21:12 < t4nk_freenode> but you said that it works on the other board
2020-07-23T21:21:28 < benishor> yes, I have one board with an on-board stlink which works
2020-07-23T21:21:29 < t4nk_freenode> therefore it would be unlikely that it's defective
2020-07-23T21:21:33 < t4nk_freenode> ah
2020-07-23T21:21:35 < t4nk_freenode> on board
2020-07-23T21:21:37 < benishor> and one board with an ob-board stlink that doesn't work anymore
2020-07-23T21:21:40 < t4nk_freenode> I didn't know that
2020-07-23T21:21:45 < benishor> pastebin seems to be working again

2020-07-23T21:22:22 < benishor> and there's the flashing red led I mentioned before on the bad board
2020-07-23T21:22:37 < benishor> whereas on the good board it doesn't flash, it's just on
2020-07-23T21:25:04 < t4nk_freenode> what happens if you set the debugger to 'software reset'?
2020-07-23T21:25:34 < t4nk_freenode> gotta run to the stores for a bit, bbl
2020-07-23T21:25:54 < benishor> I don't even mind the debugger yet
2020-07-23T21:26:06 < benishor> since I don't see the stlink registering as usb device
2020-07-23T21:27:19 < PaulFertser> benishor: probably the bad board pulls down Vcc and it's common for the target and stlink.
2020-07-23T21:27:55 < t4nk_freenode> yeah, if you want to make progress, you should do as PaulFertser says and connect the second board's stlink
2020-07-23T21:28:29 < benishor> t4nk_freenode: yeah, I'm not just interested in flashing the bad board somehow but I'm interested in finding the culprit
2020-07-23T21:28:34 < benishor> and fixing the problem if possible
2020-07-23T21:28:36 < t4nk_freenode> but you need to take some action at some point .. it won't miraculously solve 
2020-07-23T21:29:21 < benishor> PaulFertser: the bad board is configured to use the stlink usb power to power up the uC
2020-07-23T21:29:24 < benishor> and it works
2020-07-23T21:29:39 < benishor> so the power rails must be ok
2020-07-23T21:29:39 < t4nk_freenode> well... taking these actions IS the way to finding the culpret.
2020-07-23T21:29:54 < t4nk_freenode> but if you think it isn't.. that's on you ;)
2020-07-23T21:30:01 < t4nk_freenode> I'm in a hurry in any case
2020-07-23T21:30:02 < t4nk_freenode> bbl
2020-07-23T21:30:22 < benishor> the main question is why doesn't stlink on the bad board register itself as an usb device
2020-07-23T21:30:25 < benishor> on the host computer
2020-07-23T21:30:46 < benishor> the cable is OK since I use it on the other board and it works
2020-07-23T21:31:30  * t4nk_freenode has a look at benishor's board, hands folded behind his back... nope.. I can't spot anything
2020-07-23T21:31:49 < benishor> this means that either the stlink chip is ded or that some usb data connection is dead somewhere between the USB connector and the stlink chip
2020-07-23T21:32:27 < benishor> what I'm looking for is a differential diagnosis

2020-07-24T02:52:57 < Laurenceb> hat pic looks like two women but really its a picture of two women and a butt. the most important part of the pic is the butt which you can see because of the butt enhancing pants. the pic was chosen because it showed the butt more than other pics, in fact there are probably thousands of pictures like this taken until the exact amount of butt is in
2020-07-24T02:52:57 < Laurenceb> the pic to satisfy the lower ape swollen bum mind process of the butt having butt enhancing pants wearing female

2020-07-24T11:54:23 < benishor> so, the problem I had with the onboard stlink
2020-07-24T11:54:24 < benishor> I fixed it
2020-07-24T11:54:40 < benishor> first I verified that usb lines were in good order and reached the stlink uC pins
2020-07-24T11:54:50 < benishor> then I concluded the stlink chip was ded
2020-07-24T11:54:58 < benishor> and luckily I had a previously blown board
2020-07-24T11:55:07 < benishor> and transplanted the stlink chip from that
2020-07-24T11:55:12 < benishor> and it works \o/
2020-07-24T11:56:00 < benishor> is the stlink firmware available anywhere? say I want to program a bare chip 
2020-07-24T11:58:13 < PaulFertser> benishor: well, unofficially, yes
2020-07-24T11:58:58 < PaulFertser> benishor: flash bootloader https://github.com/Krakenw/Stlink-Bootloaders then use stlink update utility
2020-07-24T11:59:20 < PaulFertser> benishor: so dead stlink, eh, do you have any idea what happened? ESD?
2020-07-24T11:59:35 < benishor> I'm not sure, might be
2020-07-24T11:59:45 < benishor> I have a 3yo kid who likes to mingle with my stuff
2020-07-24T12:00:06 < benishor> I had that board plugged in for the last days as I was working on my transceiver sw
2020-07-24T12:00:22 < benishor> and the kid is attracted to the lcd
2020-07-24T12:00:35 < benishor> possibly a short? esd? I'm not sure
2020-07-24T12:01:47 < PaulFertser> Oh wow, nice https://github.com/Krakenw/Stlink-Bootloaders/pull/3
2020-07-24T12:04:21 < benishor> I'm lost as to how I'd flash those bootloaders on a fresh uC
2020-07-24T12:04:23 < benishor> any help?
2020-07-24T12:05:13 < srk> skip the bootloader if it's not SWD locked 
2020-07-24T12:05:33 < srk> looks like bootloader is needed to overcome protection level 2 which disables SWD
2020-07-24T12:05:51 < srk> for vendors ST-Links
2020-07-24T12:07:34 < PaulFertser> benishor: not sure what you're asking, just use SWD to connect to the stlink chip and flash the binary? Can also be performed via UART bootloader.
2020-07-24T12:08:34 < benishor> PaulFertser: oh, so it's like flashing a regular program
2020-07-24T12:08:51 < benishor> I thought there was something specific to flashing a bootloader
2020-07-24T12:09:22 < PaulFertser> benishor: not on stm32
2020-07-24T12:09:30 < srk> is that v3 stlink?
2020-07-24T12:09:39 < benishor> PaulFertser: I see, thanks a lot!
2020-07-24T12:10:33 < PaulFertser> I assume not, v2 or v2-1.
2020-07-24T12:11:00 < srk> well, just flash blackmagic :)
2020-07-24T12:12:37 < dongs> fucking bullshit
2020-07-24T12:12:54 < dongs> thermapp came with a fucking bullshit nonstandard micro-b OTG cable
2020-07-24T12:13:07 < dongs> and i cant fucking figure out how to make it work in a type C phoen
2020-07-24T12:13:15 < dongs> god damn jews
2020-07-24T12:15:00 < dongs> ok looks like 5K PD on CC to activate OTG
2020-07-24T12:15:31 < dongs> not like it really matters tho cuz i dont have any breakout for a shitty type C connector anyway
2020-07-24T12:16:01 < dongs> and for sure a chink charger typeC isnt gonna breakout cc
2020-07-24T12:17:16 < zyp> just cut off the shitty plug and solder the cable to something useful
2020-07-24T12:17:46 < dongs> hm 5.1k to ground thats how i do all my usb devices tho
2020-07-24T12:17:54 < dongs> does that trigger OTG when its plugged into phone end??
2020-07-24T12:18:10 < dongs> zyp, what shitty plug
2020-07-24T12:18:15 < zyp> well, duh
2020-07-24T12:18:19 < dongs> i need type C "otg"
2020-07-24T12:18:23 < zyp> OTG is not a special mode
2020-07-24T12:18:36 < zyp> there's a host end and a device end, device end has 5.1k pulldown
2020-07-24T12:18:52 < dongs> this is a bullshit microb otg device tho
2020-07-24T12:18:57 < dongs> so i will have to negro a cable
2020-07-24T12:19:03 < dongs> somehow
2020-07-24T12:19:04 < zyp> exactly, cut off the microb shit
2020-07-24T12:19:20 < zyp> or make a nonstandard microb to c adapter
2020-07-24T12:19:22 < dongs> but CC isnt gonna be connceted to anything on typeC side
2020-07-24T12:20:00 < zyp> do you have usb-c sockets?
2020-07-24T12:20:23 < dongs> not exactly solderable but i guess
2020-07-24T12:20:27 < dongs> the 14pin shit
2020-07-24T12:20:36 < zyp> could probably deadbug it
2020-07-24T12:21:07 < dongs> so what do i do? typeC-C cable from phone to this socket, then pulldown 5.1k to gnd, and connect dpdm to the micro-b end?
2020-07-24T12:21:28 < dongs> lets see if I can do this without trashing something
2020-07-24T12:21:45 < zyp> correct
2020-07-24T12:22:07 < zyp> I'd deadbug a microb and usbc socket, wire gnd, dp/dm and vbus across
2020-07-24T12:22:14 < zyp> then 5.1k to gnd on each cc
2020-07-24T12:23:25 < dongs> i got a pcb with typeC on it and 5.1ks, maybe it will be easier to split up microB and fit into this
2020-07-24T12:23:28 < dongs> trying now.
2020-07-24T12:25:53 < zyp> just cut off the shitty microb and solder the cable to that board then?
2020-07-24T12:26:40 < dongs> thats the plan now that i found the board
2020-07-24T12:31:57 < zyp> the usbc pmod shit that I designed should also be usable for this, so you should make some soon :p
2020-07-24T12:44:37 < kakimir> so.. a pizza box computer it is

2020-07-24T21:45:49 < benishor> Mangy_Dog: omg
2020-07-24T21:46:22 < benishor> do show when it's on
2020-07-24T21:47:10 < Mangy_Dog> will do
2020-07-24T21:47:14 < Mangy_Dog> also will have a video on it
2020-07-24T21:47:56 < benishor> I'm curious how much more visible it is compared to a regular 7/16 seg display with no filter
2020-07-24T21:48:20 < qyx> I have a 358ns of RG174U cable
2020-07-24T21:48:26 < qyx> how much is that
2020-07-24T21:49:19 < qyx> 42m?
2020-07-24T21:49:29 < Mangy_Dog> ben no idea
2020-07-24T21:49:39 < Mangy_Dog> though these will get a face put on
2020-07-24T21:49:45 < Mangy_Dog> i wanted to test it first before gluing the faces i made
2020-07-24T21:50:00 < Mangy_Dog> i would say....... so expect this to compare with commercial units
2020-07-24T21:50:08 < Mangy_Dog> its an entirely maker made thing
2020-07-24T21:58:16 < benishor> qyx: depends on the frequency, no?
2020-07-24T21:59:20 < benishor> qyx: actually it appears not

2020-07-24T22:04:16 < benishor> given propagation velocity of rg174u as 66%
2020-07-24T22:05:19 < qyx> interesting, I found 0.78
2020-07-24T22:05:42 < benishor> https://www.pasternack.com/images/ProductPDF/RG174A-U.pdf
2020-07-24T22:05:46 < benishor> I went with this spec
2020-07-24T22:07:36 < benishor> actually somewhere around ~35.5meters
2020-07-24T22:07:47 < benishor> I brainfarted and used 60% instead of 66% 
2020-07-24T22:08:10 < benishor> 358E-9*300E6*0.66/2
2020-07-24T22:08:32 < benishor> 358E-9*300E6*0.78/2 = 41.886
2020-07-24T22:08:42 < benishor> I'd say you measure the cable and find out the real velocity factor :)

2020-07-24T22:30:35 < zyp> and now somebody has apparently managed to blow up a couple of the other inputs so they always read pressed
2020-07-24T22:31:59 < zyp> combine that with a firmware that doesn't properly support the change to bootloader command, and you have a recipe for fun
2020-07-24T22:38:10 < bitmask> this design i downloaded uses just 1x 40mm fan over the mcu. is that enough airflow for the stepper drivers on the right? 
2020-07-24T22:38:12 < bitmask> https://i.imgur.com/XuxnNfA.png
2020-07-24T22:39:05 < qyx> zyp: :d
2020-07-24T22:41:40 < PaulFertser> But blown inputs probably mean the MCU is to be replaced anyway?
2020-07-24T22:45:46 < zyp> eh, if the rest works, why throw it away?
2020-07-24T22:46:30 < PaulFertser> An unused input is unlikely to get blown, and a used one was most likely, ahem, useful (that's my reasoning)
2020-07-24T22:46:36 < zyp> there's 11 button inputs, only two were blown, I believe they're only using seven in total anyway
2020-07-24T22:46:45 < zyp> they are interchangeable
2020-07-24T22:47:11 < zyp> and they were probably blown because they plugged some other shit into a button connector :p
2020-07-24T22:48:25 < PaulFertser> Why can't they just reflash via SWD then if they're already messing with the hardware?

2020-07-24T22:51:08 < antto> what for
2020-07-24T22:51:20 < PaulFertser> antto: or you can just try testing the patched firmware since the suspect function is already known.
2020-07-24T22:52:12 < antto> i have left my arm cortext board to blink under multiple layers of dust
2020-07-24T22:52:20 < PaulFertser> antto: hm, I sometimes end up reading disassembled code of my own programs when debugging and it helps to see where I'm doing something wrong/odd leading to UB or just not what I wanted.
2020-07-24T22:52:24 < zyp> PaulFertser, you assume that everybody that's able to plug a plug into a socket has the skills and equipment to swd?
2020-07-24T22:53:07 < PaulFertser> zyp: tbh, I'm bad at assumptions especially about people but raspberrypi can do 3.3 V SWD without any serious effort afaik.
2020-07-24T22:53:33 < zyp> okay, let me put it like this
2020-07-24T22:53:55 < zyp> my usb-adapter board is designed to be plug and play compatible with a certain chinese brand of game controllers
2020-07-24T22:54:21 < zyp> this person tried putting it in a different brand controller that happens to be using the same kind of plugs, but with a different pinout
2020-07-24T22:55:36 < antto> PaulFertser i remember i heard about this radare2 and cutter, installed it, loaded some xmega .hex, it looked fancy, there was a way to change it to show sorta short explanation after each asm instruction which was nice.. but then wot.. it's like a 37KB firmware compiled in C++ mode and with -flto
2020-07-24T22:55:45 < PaulFertser> I see, that explains your story. The choice of bootloader entry method is indeed unfortunate for this kind of circumstances, and I think many of us can learn from this experience, thanks for sharing.
2020-07-24T22:56:17 < qyx> "a chinese plug"
2020-07-24T22:56:36 < antto> qyx pls NSFW ur thoughts
2020-07-24T22:56:49 < zyp> the original board is apparently using the same kind of plug for the usb input, as well, so I assume what happened is that that ended up in a button socket, and either fed 5V into a non 5V-tolerant GPIO, or maybe even reverse polarity
2020-07-24T22:57:32 < qyx> you are kidding zyp
2020-07-24T22:57:45 < zyp> nope
2020-07-24T22:57:49 < qyx> no rp nor overvoltage protection
2020-07-24T22:57:50 < PaulFertser> I fed 14 V into an atmega ADC input once, surprisingly only that specific input blew.
2020-07-24T22:58:06 < PaulFertser> You can't protect against everything qyx .
2020-07-24T22:58:13 < zyp> qyx, eh, I'm selling cheap shit, no budget for that :)
2020-07-24T22:58:31 < qyx> you can for the majority
2020-07-24T22:58:46 < qyx> but the cheap is probably the keyword here
2020-07-24T22:58:51 < zyp> so anyway, I made them a workaround
2020-07-24T22:58:52 < qyx> -the
2020-07-24T22:59:08 < PaulFertser> Also, you can make something foolproof, but you are unlikely to really make something "inventive fool"-proof.
2020-07-24T22:59:57 < zyp> the reason the normal bootloader switch command didn't work (HID feature report) is because the firmware pretended to be a keyboard and windows doesn't allow direct HID access to keyboards
2020-07-24T23:00:21 < antto> mmm, not long ago i set the multimeter to VAC mode, switched the red probe to the "bigger" position, and probed the wall outlet x_x
2020-07-24T23:00:23 < zyp> so I had them bind it to winusb and made a libusb thing to send the command

2020-07-25T00:15:59 < Mangy_Dog> Are esp8266 compiles normally very slow? This is taking minutes rather than the seconds im used to on atmega and stm32
2020-07-25T00:16:28 < zyp> I've got a four pin connector with 5V, fixed ground, switched ground and input with pullup
2020-07-25T00:17:05 < zyp> there's a light between 5V and switched ground and a button switch between fixed ground and input with pullup
2020-07-25T00:17:24 < qyx> use a relay switching matrix like ATE guys do
2020-07-25T00:17:41 < zyp> what would be the cheapest way to be able to switch this dynamically?
2020-07-25T00:19:02 < qyx> use pullups on all four
2020-07-25T00:19:08 < qyx> hm
2020-07-25T00:19:28 < qyx> maybe a 4 channel power push-pull driver?
2020-07-25T00:19:57 < qyx> and connect all to GPIO inputs too with a big enough resistor
2020-07-25T00:20:04 < zyp> yeah, any specific suggestions? I've toyed with the idea of SLG47105 which includes four half bridges
2020-07-25T00:20:14 < zyp> they are $.5
2020-07-25T00:20:17 < qyx> is this the special silego thing?
2020-07-25T00:20:25 < zyp> yeah, the hvpak thing
2020-07-25T00:20:30 < zyp> https://www.dialog-semiconductor.com/products/slg47105
2020-07-25T00:21:23 < qyx> do you need a permanent configuration?
2020-07-25T00:21:37 < qyx> ir can you scan all groups in a sequence
2020-07-25T00:21:57 < zyp> what do you mean?
2020-07-25T00:22:52 < qyx> oh theres a light, so probably not
2020-07-25T00:23:05 < qyx> I mean constructing one such multipurpose 4 IO port
2020-07-25T00:23:11 < qyx> and then analog-muxing it to multiple
2020-07-25T00:23:28 < qyx> there are some 2x16 or 4x8 Maxim multiplexers
2020-07-25T00:23:37 < qyx> switch matrices actually
2020-07-25T00:23:47 < zyp> I'm mainly concerned about having enough current to drive the leds
2020-07-25T00:24:11 < qyx> I would also check simple cmos bus buffers
2020-07-25T00:24:25 < qyx> they should be able to source a couple of 10mA
2020-07-25T00:24:31 < qyx> or sink
2020-07-25T00:25:20 < qyx> with them you could make permanent gnd, switched gnd, switched/permanent 5V and floating to detect button switches
2020-07-25T00:27:49 < zyp> I also have >10 of these sockets
2020-07-25T00:30:22 < zyp> so the silego things are more than the rest of the BOM :)
2020-07-25T00:31:17 < catphish> could you guys maybe have slightly more different nicks?

2020-07-25T00:36:01 < zyp> some of the lowend ones are $.15
2020-07-25T00:36:37 < PaulFertser> bitmask: for what purpose?
2020-07-25T00:37:01 < bitmask> thats the problem, I dont know.  the one thing I need it for doesnt matter
2020-07-25T00:37:06 < PaulFertser> PETG then
2020-07-25T00:37:36 < bitmask> that was my original thought but now im leaning towards pla since I plan on ordering a carbon fiber petg soon
2020-07-25T00:38:38 < PaulFertser> qyx: at least regarding Linux, the kernel, the new proposed terminology seems to be better, less ambiguous, more to the point. 
2020-07-25T00:39:05 < zyp> hmm, plain greenpak outputs appears to be limited below 20mA though
2020-07-25T00:39:31 < PaulFertser> bitmask: what case do you consider PLA to be beneficial for?
2020-07-25T00:40:56 < zyp> easier to print?
2020-07-25T00:40:57 < bitmask> well the two things im thinking about are stiffness and ease of printing (aka quality of result)
2020-07-25T00:45:16 < PaulFertser> PETG tends to be more stringy indeed. But regarding stiffness, isn't PLA a bit too stiff and so more likely to snap?
2020-07-25T00:46:05 < bitmask> depends how thin the part is
2020-07-25T00:46:32 < bitmask> i mean the answer is yes but depends on what its for if that matters
2020-07-25T00:47:06 < bitmask> and sometimess the 'too stiff' is what you want
2020-07-25T00:47:23 < bitmask> I guess im mainly printing project cases
2020-07-25T00:47:28 < bitmask> so petg is probably better
2020-07-25T00:47:33 < PaulFertser> I've read PLA can also be kinda hardened a bit.
2020-07-25T00:47:40 < Steffanx> Lol bitmask, stop kakimiring.
2020-07-25T00:47:41 < bitmask> it can be annealed
2020-07-25T00:47:43 < Mangy_Dog> well this is a greate start, i cant even upload to my esp8266 :/ it fails to find it
2020-07-25T00:47:52 < bitmask> Steffanx hah no
2020-07-25T00:47:59 < Mangy_Dog> i can see teh com port
2020-07-25T00:48:04 < Mangy_Dog> but it doesnt upload :/
2020-07-25T00:48:13 < Steffanx> I mean. First ask a question and then the requirements come after people give suggestions. Aka kakimiring
2020-07-25T00:48:56 < bitmask> ahh, well I'm not really sure what im gonna use it for, the project cases is me just guessing
2020-07-25T00:49:33 < Steffanx> I like petg more. Especially since the petg i use isnt even that stringy
2020-07-25T00:49:42 < Steffanx> And less brittle than pla
2020-07-25T00:50:06 < PaulFertser> bitmask: so basically to redue brittleness, not to increase, ok.
2020-07-25T00:51:00 < bitmask> im actually not sure what annealing does, never tried it, I think it makes it more temperature resistant somehow
2020-07-25T00:52:04 < bitmask> ive been wondering if pla would be better for parts for a 3D printer, parts not close to the hotend
2020-07-25T00:52:05 < PaulFertser> Steffanx: I have an impression that one has to trade layer adhesion for lack of strings. In my testing the maximum strength was beyond the points I could make it not string.

2020-07-25T00:53:11 < PaulFertser> Steffanx: I mean I was getting the temperature higher and higher and maximum strength was when it was too high for a clean print. 
2020-07-25T00:53:18 < Steffanx> Idk to behonest. I mainly concluded it also heavily dependents on the used brand. For me
2020-07-25T00:53:50 < bitmask> I use atomic filament for stuff that matters
2020-07-25T00:54:34 < PaulFertser> I usually print a calibration cube where each wall is exactly two perimeters of 0.5 mm. That allows to adjust the flow but also I use a utility knife to see how hard it is to separate the layers.

2020-07-25T01:15:33 < zyp> but I need a bunch, and therefore a way to set the i2c addr, which eats four pins
2020-07-25T01:21:42 < zyp> another option is to buffer each pin with a SN74LVC1T45
2020-07-25T01:22:24 < zyp> that'll just need four times as much IO as I'm using now :)
2020-07-25T01:41:36 < qyx> is there an arduino specialist?
2020-07-25T01:41:54 < qyx> how to get the "arduino functionality" on a custom extension board?
2020-07-25T01:42:58 < qyx> oh easier than I though https://www.instructables.com/id/Getting-Started-With-Stm32-Using-Arduino-IDE/
2020-07-25T01:43:01 < zyp> the what
2020-07-25T01:43:35 < qyx> for marketing purposes :>

2020-07-25T01:45:13 < qyx> and a lib to communicate with the rest of the system

2020-07-25T12:35:44 < Jak_o_ARGH> Is this stackoverflow page sensible for a STM32f042f6p6? I've spun up a new board (first time!), and it doesn't quite seem to be working
2020-07-25T12:35:45 < Jak_o_ARGH> https://stackoverflow.com/a/60245957
2020-07-25T12:36:19 < Jak_o_ARGH> I seem to be able to connect via openOCD, and flashing seems o work.
2020-07-25T12:40:13 < PaulFertser> Jak_o_ARGH: your question is underspecified
2020-07-25T12:40:19 < PaulFertser> Jak_o_ARGH: what exactly is the issue?
2020-07-25T12:40:43 < dongs> yewah i was gonna ask what exactly is the question
2020-07-25T12:40:54 < PaulFertser> Jak_o_ARGH: make sure the RAM amount you specify in the linker script matches your particular chip on board.
2020-07-25T12:41:18 < Jak_o_ARGH> yeah. Not great at asking questions right now
2020-07-25T12:41:29 < Jak_o_ARGH> It doesn't seem to be executing the code, is the core of it.
2020-07-25T12:41:41 < Jak_o_ARGH> I am thinking that with my PCB design, I stuffed up the boot pin
2020-07-25T12:41:57 < Jak_o_ARGH> in that I completely ignored it and left it floating
2020-07-25T12:42:06 < PaulFertser> Jak_o_ARGH: do "reset halt" then stepi stepi si
2020-07-25T12:43:30 < PaulFertser> Jak_o_ARGH: do not let boot pin floating.
2020-07-25T12:45:43 < Jak_o_ARGH> Yep. That's a lesson.
2020-07-25T12:46:40 < Jak_o_ARGH> At least it's pin 1 on the TSSOP20, so it'll be easy enough to bodge
2020-07-25T12:46:41 < PaulFertser> stepping from reset vector would reveal PC address is not what you expect
2020-07-25T12:47:09 < Jak_o_ARGH> Yeah - it did work once, the code was running.
2020-07-25T12:47:18 < Jak_o_ARGH> but that's not unsurprising if you just leave it floating is it
2020-07-25T12:47:21 < PaulFertser> I'd say any pin on TSSOP20 is reasonably easy to connect.
2020-07-25T12:48:30 < Jak_o_ARGH> That's probably true, but this is my first surface mount project
2020-07-25T12:51:33 < Jak_o_ARGH> If it wouldn't take 2 months to get new PCBs, i'd just get a new one.

2020-07-25T14:34:00 < Mangy_Dog> god why did bitwise have to be so hard 
2020-07-25T14:36:37 < Mangy_Dog> whats !!
2020-07-25T14:37:34 < zyp> bitwise?
2020-07-25T14:37:35 < Mangy_Dog> digitalWrite(dataPin, !!(val & (1 << i)));
2020-07-25T14:37:42 < zyp> not not
2020-07-25T14:37:52 < Laurenceb> oh god
2020-07-25T14:37:56 < Laurenceb> tarduino
2020-07-25T14:37:58 < zyp> I don't like that pattern
2020-07-25T14:38:03 < Mangy_Dog> just tryign to come up with my own shift reg shifter for my digits so i can handle the charactor data
2020-07-25T14:38:18 < Mangy_Dog> but this is from the arduino shiftout function
2020-07-25T14:38:27 < Mangy_Dog> was using it to try and get a basic understanding of how IT does it
2020-07-25T14:38:28 < zyp> !!(x) is equivalent to ((x) ? 1 : 0), I prefer the latter
2020-07-25T14:38:32 < Mangy_Dog> but the !!
2020-07-25T14:39:25 < zyp> well, you're testing (val & (1 << i))
2020-07-25T14:39:29 < zyp> let's say i=4
2020-07-25T14:39:50 < zyp> then you get either 0 or 1 << 4, which is 16
2020-07-25T14:39:52 < Mangy_Dog> its part of a 8 cycle loop for a 8bit shift out
2020-07-25T14:40:08 < zyp> but you don't want 0 or 16, you want 0 or 1
2020-07-25T14:40:39 < zyp> !(16) is 0, !(0) is 1
2020-07-25T14:40:44 < zyp> so !!(16) is 1
2020-07-25T14:41:10 < zyp> also !(0) is 1 and !(1) is 0, so !!(0) is 0
2020-07-25T14:41:52 < Mangy_Dog> im not going to lie, this is confusing
2020-07-25T14:42:17 < zyp> i.e. !!(x) gives you 0 if x==0, otherwise it gives you 1
2020-07-25T14:42:57 < zyp> so it's a simple way to turn every expression that evaluates true into an actual 1
2020-07-25T14:43:05 < Mangy_Dog> ok
2020-07-25T14:44:33 < Mangy_Dog> also not going to lie digitalWrite(dataPin, !!(val & (1 << i))); is making my brain hurt trying to follow what its doing
2020-07-25T14:46:32 < Steffanx> So dont copy such code
2020-07-25T14:46:37 < zyp> (1 << i) creates a one-bit bit mask that selects bit i
2020-07-25T14:46:59 < zyp> (val & mask) uses the mask to pick out that particular bit from val
2020-07-25T14:47:06 < zyp> and !! converts it to 0 or 1
2020-07-25T14:47:50 < Steffanx> So write some app on your desktop pc and print the values of all operations/steps Mangy_Dog 
2020-07-25T14:48:03 < zyp> e.g. if val = 0b10101 and i = 2, then (1 << 2) is 0b00100
2020-07-25T14:48:06 < Steffanx> The you can kinda see what happens
2020-07-25T14:48:09 < Mangy_Dog> tbh im not even sure why im trying to follow it... im taking my 16bit defines for my 4x4 matrix of led charactor data... doing a 4 cycle loop and placing the upper 4 bits of that 8 bit 4 cycle loop (whats being shifted out) with each 4 bit chunk of the 16bit define
2020-07-25T14:48:18 < zyp> 0b10101 & 0b00100 -> 0b00100
2020-07-25T14:48:25 < zyp> and !!(0b00100) -> 1
2020-07-25T14:49:13 < zyp> for i = 3, mask = 0b01000, 0b10101 & 0b01000 -> 0b00000 and !!(0b00000) -> 0
2020-07-25T14:51:44 < zyp> maybe it gets more understandable if you rewrite the entire expression
2020-07-25T14:52:04 < zyp> instead of !!(val & (1 << i)), you can do ((val >> i) & 1)
2020-07-25T14:52:36 < Mangy_Dog> not relaly :D
2020-07-25T14:52:39 < Mangy_Dog> really
2020-07-25T14:52:53 < zyp> right shift val to get bit i at the bottom, then use bitwise and to throw away everything except the bottom bit
2020-07-25T14:53:15 < Mangy_Dog> i dont know if its because im dyslexic and holding complex numbers in my head isnt the easiest of tasks for me... or im just not that bright!
2020-07-25T14:53:35 < Mangy_Dog> oh ok that actually makes more sense
2020-07-25T14:54:04 < Mangy_Dog> though i also think part of the issue is ive not really learnt bitwise properly and nor is symbols soooo it dosnt just come naturally to me
2020-07-25T14:54:36 < zyp> you probably just need to get used to think about numbers in binary
2020-07-25T14:54:53 < Mangy_Dog> that too
2020-07-25T14:55:53 < zyp> I mean, what you're doing is equivalent to having the number 12345 in decimal and picking out the digit in the hundreds position
2020-07-25T14:55:54 < Steffanx> If holding the numbers in your head is hard. Why dont you write them down?
2020-07-25T14:56:34 < Steffanx> Might even be some enlightenment when you see what happens
2020-07-25T14:56:37 < Mangy_Dog> i do that too sometimes
2020-07-25T14:56:41 < Mangy_Dog> as well as function flows
2020-07-25T14:56:54 < Mangy_Dog> for when things get a little more complicated
2020-07-25T14:57:21 < Mangy_Dog> same when visualising maths 
2020-07-25T14:57:25 < Mangy_Dog> for functions
2020-07-25T14:57:48 < zyp> if you divide 12345 by 100 and throw away the remainder, you get 123, if you divide that by 10 and only look at the remainder you've got 3
2020-07-25T14:58:11 < Mangy_Dog> ohh i get >> << bit
2020-07-25T14:58:14 < zyp> i.e. ((12345 / 100) % 10)
2020-07-25T14:58:15 < Mangy_Dog> thats the easy bit
2020-07-25T14:59:03 < Mangy_Dog> its when you start throwing in AND XOR OR NOTs in it gets a little confusing sometimes
2020-07-25T14:59:14 < Mangy_Dog> esp when youre seeing it in symboles rather than written
2020-07-25T14:59:25 < zyp> true
2020-07-25T15:00:01 < zyp> you can think of bitwise and as a digit-wise multiplication
2020-07-25T15:00:45 < zyp> e.g. to achieve something like your first expression, you can do a digit-wise multiplication between 12345 and 00100
2020-07-25T15:01:55 < zyp> the 00100 is 10 to the power of 2
2020-07-25T15:02:04 < zyp> 0b00100 is 2 to the power of 2
2020-07-25T15:02:19 < zyp> 1 << i is equivalent to 2**i
2020-07-25T15:03:09 < Mangy_Dog> you mean i to the power of 2?
2020-07-25T15:03:15 < Mangy_Dog> 1<<2
2020-07-25T15:03:30 < Mangy_Dog> gah
2020-07-25T15:03:32 < zyp> no, 2 to the power of i
2020-07-25T15:03:53 < zyp> remember that 1 << 0 is 1
2020-07-25T15:03:58 < zyp> 2**0 is also 1
2020-07-25T15:04:14 < zyp> 1 << 1 is 2, 2**1 is also 2
2020-07-25T15:04:43 < Mangy_Dog> nods
2020-07-25T15:04:50 < zyp> and in decimal 10**0 is 1, 10**1 is 10 and 10**2 is 100
2020-07-25T15:05:44 < Mangy_Dog> nodnods
2020-07-25T15:05:54 < Mangy_Dog> i get that
2020-07-25T15:06:07 < zyp> much of the math is the same between binary and decimal, it's just that digit-wise operations is not very common in decimal
2020-07-25T15:07:16 < zyp> I mean, you do it when you add or multiply digit by digit, but in that case you add in carry as well
2020-07-25T15:07:24 < zyp> in bitwise you don't carry
2020-07-25T15:08:21 < Mangy_Dog> nodnods
2020-07-25T15:08:32 < Mangy_Dog> annnnd i should actually try and write this function now
2020-07-25T15:08:36 < zyp> :)
2020-07-25T15:08:39 < Mangy_Dog> had a second strong coffee

2020-07-25T15:11:24 < Mangy_Dog> had to look up the ali order to see what one i got
2020-07-25T15:11:36 < zyp> f_MAX is at the top of page 5
2020-07-25T15:11:47 < zyp> it varies with voltage and temperature
2020-07-25T15:12:47 < zyp> looks like you can safely run it at 10 MHz at least
2020-07-25T15:13:35 < Mangy_Dog> where did you see that?
2020-07-25T15:13:40 < Mangy_Dog> cant see fmax anywhere

2020-07-25T15:14:02 < Mangy_Dog> page 6 table?
2020-07-25T15:14:02 < zyp> first parameter on page 5 in the document you linked
2020-07-25T15:14:17 < Mangy_Dog> lol
2020-07-25T15:14:19 < Mangy_Dog> yeah
2020-07-25T15:14:56 < zyp> that's the bit clock, so divide that by the number of bits you need to shift per update and you have an estimated max update rate
2020-07-25T15:15:05 < Mangy_Dog> nods
2020-07-25T15:15:45 < zyp> and I assume you're bitbanging this, since we were talking about digitalWrite
2020-07-25T15:15:49 < Mangy_Dog> 1666,666hz
2020-07-25T15:16:06 < Mangy_Dog> 166,666
2020-07-25T15:16:25 < Mangy_Dog> in this case 15 digits
2020-07-25T15:16:34 < Mangy_Dog> 4 cycles per digit
2020-07-25T15:16:54 < Mangy_Dog> but have to do row a of all 16 digits then row b then c then d
2020-07-25T15:17:06 < Mangy_Dog> to make a character display
2020-07-25T15:17:26 < zyp> how is your leds organized? got a schematic?
2020-07-25T15:17:54 < Mangy_Dog> the chips are powered on 5v but the latch clk and first data input is 3.3v off a esp8266
2020-07-25T15:18:34 < Mangy_Dog> https://cdn.discordapp.com/attachments/695271473308237985/736557977426985041/unknown.png
2020-07-25T15:19:05 < zyp> ah, each digit is an independent 4x4 matrix
2020-07-25T15:19:11 < Mangy_Dog> and the leds are laid out like this https://cdn.discordapp.com/attachments/695271473308237985/736558118774898828/unknown.png
2020-07-25T15:19:15 < Mangy_Dog> nods
2020-07-25T15:19:52 < Mangy_Dog> its not going to be the fastest flicker free display
2020-07-25T15:20:02 < Mangy_Dog> but as long as its readable im happy
2020-07-25T15:20:35 < Mangy_Dog> ill get the bitbanged digital write working then ill move to esp8266 direct port manipulation to try and speed things up as much as i safely can
2020-07-25T15:20:58 < zyp> you could have saved yourself a lot of hassle by just going with two shift registers (or a single 16-bit one) :)
2020-07-25T15:21:07 < Mangy_Dog> not at all
2020-07-25T15:21:10 < Mangy_Dog> wouldnt fit
2020-07-25T15:21:36 < Mangy_Dog> https://cdn.discordapp.com/attachments/538814618106331139/736275167268962447/IMG_20200724_183339.jpg

2020-07-25T15:22:10 < Mangy_Dog> i wanted the digits to be modular and daisychainable

2020-07-25T15:22:53 < Mangy_Dog> though with a chain as big as in this display I looped the ground and 5v feed to the other end of the chain to help releave stress on the 5v and gnd traces
2020-07-25T15:24:27 < Mangy_Dog> btw when this project is done im actually going to release all source files for it
2020-07-25T15:24:44 < Mangy_Dog> so if anyone wanted to make one
2020-07-25T15:24:45 < zyp> Mangy_Dog, hmm, I think it would, remember that you don't need Q7-10 and could reuse that area
2020-07-25T15:24:45 < Mangy_Dog> theyc ould

2020-07-25T15:32:35 < Mangy_Dog> noi mean i couldnt physically fit the chips into the chiplet design
2020-07-25T15:32:40 < Mangy_Dog> and route it
2020-07-25T15:32:48 < dongs> i cant get this macfag to enter internet recovery by holding alt-ctrl-shift-R what am i doing wrong
2020-07-25T15:32:53 < Mangy_Dog> the routing on this is already pushing jlcs rules
2020-07-25T15:32:55 < dongs> (i dont have an applefag keyboard)

2020-07-25T15:41:14 < effractur> ar you using the onboard keyboard or externaly?
2020-07-25T15:41:31 < dongs> wat is 'onboard keyboard'? this is a fagmini so theres no ckeyboard.
2020-07-25T15:41:46 < dongs> i did plug it into the nearest to center USB port as that is a requirement for mac to recognize a keyboard in boot (lol)
2020-07-25T15:42:36 < effractur> command+r should be enough 
2020-07-25T15:42:42 < effractur> if it is modern enough
2020-07-25T15:43:21 < effractur> that shift ctrl alt stuff is gone it seems
2020-07-25T15:43:29 < effractur> does it has a t2?
2020-07-25T15:44:24 < effractur> command+option+r should work or only command+r
2020-07-25T15:44:45 < effractur> and on a non apple keyboard you should use the left alt not the right one
2020-07-25T15:56:40 < dongs> lul this fucking corsair faggot rgb keyboard doesnt boot fast enough for macfag to catch the input key
2020-07-25T15:56:50 < dongs> or maybe it doesnt accept pressing keys on power-on

2020-07-25T17:24:27 < Mangy_Dog> ohhhh poop
2020-07-25T17:24:45 < Mangy_Dog> the flicker i was getting is from the pwm control not the bitshift speed
2020-07-25T17:24:57 < Mangy_Dog> esp8266 max pwm is 1khz
2020-07-25T17:25:00 < Mangy_Dog> :/
2020-07-25T17:25:05 < Mangy_Dog> thats not very fast
2020-07-25T17:25:29 < Mangy_Dog> and im getting phase misses with the pwm vs the bitshift cycle
2020-07-25T17:25:59 < zyp> yeah, you should see if you could lock them somehow
2020-07-25T17:26:26 < zyp> by e.g. latching the new values at the start of the pwm cycle
2020-07-25T17:26:38 < Mangy_Dog> yeah not sure how
2020-07-25T17:26:54 < Mangy_Dog> apparantly the PWM control in esp is software based
2020-07-25T17:26:59 < Mangy_Dog> hense its slow speed
2020-07-25T17:27:04 < Mangy_Dog> its done using timer interupts
2020-07-25T17:27:11 < zyp> oh, heh
2020-07-25T17:27:23 < Mangy_Dog> id have to learn about esp timers now too D:
2020-07-25T17:27:25 < Mangy_Dog> joy
2020-07-25T17:27:58 < zyp> well, theory remains the same whether you use interrupts or direct output compare
2020-07-25T17:28:22 < zyp> so anyway, I figure what you'll want to do will look something like this:
2020-07-25T17:29:12 < Mangy_Dog> theres function controls to set pwm frequincy up to 1000hz
2020-07-25T17:29:15 < zyp> set up two timer interrupts; one that happens at a fixed interval and one that happens a given amount of time after the first
2020-07-25T17:29:24 < Mangy_Dog> I guess i can make it a littel slower
2020-07-25T17:29:27 < zyp> I assume that's how the software pwm already works
2020-07-25T17:29:28 < Mangy_Dog> to something that can latch onto
2020-07-25T17:29:43 < zyp> first interrupt turns on the transistor, second interrupt turns it off
2020-07-25T17:29:48 < Mangy_Dog> tbh i think it basically runs just like my timer control for my reflow oven
2020-07-25T17:30:09 < zyp> so anyway, what you'll want to add is this:
2020-07-25T17:30:11 < Mangy_Dog> just at 1khz rather than my 50-60hz
2020-07-25T17:30:25 < Mangy_Dog> yeah thats how my oven works
2020-07-25T17:30:26 -!- jsoft [~jsoft@unaffiliated/jsoft] has joined ##stm32
2020-07-25T17:30:48 < zyp> in the first interrupt: strobe the latch to take the new values, then signal to other code that it should start shifting out the next set of values
2020-07-25T17:31:37 < zyp> as long as the shifting finishes during the cycle, you'll always latch fresh data that way, and the pwm will be phase locked to the updates, so each row will see the same duty
2020-07-25T17:31:39 < Mangy_Dog> nods
2020-07-25T17:32:31 < Mangy_Dog> tbh thats the least of my problems right now
2020-07-25T17:32:45 < Mangy_Dog> im breaking down what i need to do to display a character
2020-07-25T17:32:59 < Mangy_Dog> and for some reason the 4 data shift isnt displaying
2020-07-25T17:33:04 < Mangy_Dog> when the first 3 are shifted
2020-07-25T17:33:26 < Mangy_Dog> but it would show if i only shift that 4th byte
2020-07-25T17:33:51 < Mangy_Dog> confusing the heck out of me
2020-07-25T17:34:03 < Mangy_Dog> because its soooo basic it shouldnt not work
2020-07-25T17:40:01 < zyp> I would just make a lookup table
2020-07-25T17:40:26 < Mangy_Dog> sure
2020-07-25T17:40:46 < Mangy_Dog> but right now im breaking it down to bare bone parts
2020-07-25T17:40:53 < Mangy_Dog> but liek i say its not working as it should
2020-07-25T17:41:00 < Mangy_Dog> its ignoring the 4th shift send in the lid
2020-07-25T17:41:02 < Mangy_Dog> list
2020-07-25T17:41:04 < Mangy_Dog> row D
2020-07-25T17:41:38 < Mangy_Dog> digitalWrite(lat,HIGH);
2020-07-25T17:41:39 < Mangy_Dog> shiftOut(dat,clk,LSBFIRST,0b11101000);
2020-07-25T17:41:39 < Mangy_Dog> shiftOut(dat,clk,LSBFIRST,0b01000100);
2020-07-25T17:41:39 < Mangy_Dog> shiftOut(dat,clk,LSBFIRST,0b10010010);
2020-07-25T17:41:39 < Mangy_Dog> shiftOut(dat,clk,LSBFIRST,0b00110001);
2020-07-25T17:41:39 < Mangy_Dog> digitalWrite(lat,LOW);	
2020-07-25T17:41:47 < Mangy_Dog> liturally that simple
2020-07-25T17:41:55 < Mangy_Dog> should display A on the display
2020-07-25T17:50:05 < zyp> how so?
2020-07-25T17:51:09 < Mangy_Dog> as thats the 4 bytes that create the figure A
2020-07-25T17:51:12 < zyp> don't you have to loop between those four bytes? not send all four at once?
2020-07-25T17:51:24 < Mangy_Dog> shiftOut is the loop
2020-07-25T17:51:47 < Mangy_Dog> the first 4 bits are the Rows ABCD
2020-07-25T17:51:52 < zyp> but you're not latching in between them
2020-07-25T17:52:00 < Mangy_Dog> the second 4 are the leds in those rows
2020-07-25T17:52:22 < zyp> to me it looks like you're sending one row for four digits, not four rows for one digit
2020-07-25T17:52:31 < Mangy_Dog> oh ignore that latch on the code i posted that was a mistake when i was cleaning to post here
2020-07-25T17:52:36 < Mangy_Dog> it is latched 
2020-07-25T17:52:38 < Mangy_Dog> between
2020-07-25T17:52:47 < zyp> ah, right
2020-07-25T17:53:08 < zyp> have you turned off pwm?
2020-07-25T17:53:16 < Mangy_Dog> no
2020-07-25T17:53:21 < Mangy_Dog> rather not run these at 100%
2020-07-25T17:53:31 < Mangy_Dog> its kinda above the current limit
2020-07-25T17:54:17 < Mangy_Dog> well it is if i screw up the code and run all leds on
2020-07-25T17:54:55 < zyp> can't it do four leds 100% on?
2020-07-25T17:55:03 < Mangy_Dog> its not 4 leds
2020-07-25T17:55:13 < Mangy_Dog> its 4*16
2020-07-25T17:55:18 < Mangy_Dog> 15
2020-07-25T17:55:23 < Mangy_Dog> per row
2020-07-25T17:55:35 < Mangy_Dog> and at the moment any charactor i aim to send will take every digit
2020-07-25T17:55:42 < zyp> which current limit are we talking about?
2020-07-25T17:55:52 < Mangy_Dog> but theres been a couple of mistakes earlier that ended up turning on ALL leds
2020-07-25T17:56:24 < Mangy_Dog> well if 4 leds per digit were on at full power that would be around 900-1000ma
2020-07-25T17:56:53 < zyp> sure, but that's a supply problem
2020-07-25T17:57:03 < Mangy_Dog> the current limit resistor is set for around 15ma i think its closer to 13ma but still
2020-07-25T17:57:08 < Mangy_Dog> the USB cable im using isnt the best
2020-07-25T17:57:13 < Mangy_Dog> its pwoer line is rather thin
2020-07-25T17:57:45 < zyp> then it'll drop voltage which would result in a lower power draw, low risk of actually breaking anything
2020-07-25T17:58:20 < Mangy_Dog> maybe so
2020-07-25T17:58:31 < Mangy_Dog> but also the traces on the pcb arent wide enough for 1amp
2020-07-25T17:58:40 < Mangy_Dog> even though i loped it round 
2020-07-25T17:58:53 < Mangy_Dog> it can run at full power while im doing the flash update
2020-07-25T17:58:59 < Mangy_Dog> but its just not somethign i want to leave going
2020-07-25T17:59:18 < Mangy_Dog> esp if i make that mistake in the bitwise that just makes ALLLLLLLL the leds run at full power
2020-07-25T17:59:29 < zyp> I just figured it'd be easier to get the bit shifting working reliably if you didn't have to worry about syncing up with pwm
2020-07-25T17:59:54 < zyp> might be worth it to disconnect the chain so you only run one digit while testing if you're worried about the current
2020-07-25T17:59:54 < Mangy_Dog> as that would pulle 3.6 amps
2020-07-25T18:00:05 < Mangy_Dog> though im sure my computers usb power would cut of power before any damage s done
2020-07-25T18:00:19 < Mangy_Dog> the pwm sync isnt so bad i cant see when an led turns on
2020-07-25T18:00:23 < Mangy_Dog> the flicker is slight
2020-07-25T18:00:24 < Mangy_Dog> not full
2020-07-25T18:00:44 < zyp> depends how they sync up
2020-07-25T18:00:45 < Mangy_Dog> more like brown out flicker
2020-07-25T18:01:14 < zyp> maybe row D is always in the middle of the pwm low period, and therefore appears to not work
2020-07-25T18:02:45 < Mangy_Dog> i dont think so tbh... the flicker is consistant across all the other rows
2020-07-25T18:02:57 < Mangy_Dog> theres no way row D can be so perfectly out of phase as to never turn on
2020-07-25T18:03:28 < Mangy_Dog> also changing the order of the rows execusion doesnt fix it
2020-07-25T18:03:39 < zyp> what happens if … yeah that was what I was about to suggest
2020-07-25T18:03:55 < zyp> that's interesting
2020-07-25T18:04:12 < Mangy_Dog> its almost as if the transistor that govens that row isnt working.... on ALL digits
2020-07-25T18:04:22 < zyp> unlikely
2020-07-25T18:04:36 < zyp> more likely it's something in the design
2020-07-25T18:04:37 < Mangy_Dog> i do have 2 transistors/mosfets that i need to touch with a soldering iron that i have already identifide as not running
2020-07-25T18:04:39 < Mangy_Dog> but thats just 2
2020-07-25T18:05:39 < zyp> I suggest double checking the pcb layout
2020-07-25T18:06:00 < Mangy_Dog> hmmm
2020-07-25T18:06:09 < Mangy_Dog> but if i drive row D on its own
2020-07-25T18:06:12 < Mangy_Dog> it runs
2020-07-25T18:06:21 < zyp> hmm
2020-07-25T18:06:31 < zyp> can you pastebin the code? both working and not working
2020-07-25T18:06:35 < Mangy_Dog> the only difference i have with D is theres a feedback io connection on it
2020-07-25T18:06:47 < Mangy_Dog> that io is also on a 10k to the gpio input
2020-07-25T18:07:00 < Mangy_Dog> its just part of a planned automation code that detects how many digits are connected
2020-07-25T18:07:01 < zyp> oh, right
2020-07-25T18:07:43 < zyp> according to the schematic, you have the FB connected together on all 16 modules
2020-07-25T18:08:09 < Mangy_Dog> yeah
2020-07-25T18:08:20 < zyp> that's bad :)
2020-07-25T18:08:34 < Mangy_Dog> shouldnt be
2020-07-25T18:08:39 < zyp> you effectively have 16 outputs driving the same signal
2020-07-25T18:08:45 < Mangy_Dog> as im addressing the whole chain one row at a time
2020-07-25T18:09:02 < zyp> are you testing with shifting data to all 16 digits now then?
2020-07-25T18:09:32 < zyp> if not, some will be on and some will be off
2020-07-25T18:09:41 < Mangy_Dog> 15 digits
2020-07-25T18:09:50 < Mangy_Dog> and yes its just pure shifting
2020-07-25T18:09:55 < Mangy_Dog> ive not isolated digits yet
2020-07-25T18:10:16 < zyp> exactly

2020-07-25T18:10:26 < zyp> you're only sending 8 bits per row now, right?
2020-07-25T18:10:36 < zyp> or 8*15?
2020-07-25T18:10:37 < Mangy_Dog> basically
2020-07-25T18:10:44 < Mangy_Dog> 8bits per row over and over
2020-07-25T18:10:54 < zyp> right, that's what I thought
2020-07-25T18:10:58 < zyp> so here's what happens
2020-07-25T18:11:11 < zyp> you send row A to digit 1, so far so good
2020-07-25T18:11:27 < Mangy_Dog> ohhhhhhh
2020-07-25T18:11:38 < zyp> next up you send row B to digit 1, the old row A data continues through to digit 2
2020-07-25T18:11:41 < zyp> and so on
2020-07-25T18:12:07 < zyp> which means that row D will not be active on all digits at the same time
2020-07-25T18:12:37 < zyp> and since they are connected together, even if digit 1 tries to turn on Q8, you have another 14 digits that tries to turn it off
2020-07-25T18:13:14 < zyp> or since you're doing this in a loop, you might have 3-4 digits on row D, the rest turning Q8 off
2020-07-25T18:13:31 < zyp> when you have more turning off than turning on, they are stronger and wins :)
2020-07-25T18:13:41 < Mangy_Dog> yeah
2020-07-25T18:13:45 < Mangy_Dog> i see
2020-07-25T18:13:55 < Mangy_Dog> i just made a 15 cycle loop for each row
2020-07-25T18:13:58 < Mangy_Dog> and it works
2020-07-25T18:14:00 < zyp> yep
2020-07-25T18:14:35 < Mangy_Dog> btw lightning storm on the way... i might loow power
2020-07-25T18:14:38 < Mangy_Dog> loose
2020-07-25T18:14:46 < Mangy_Dog> and yeah thats how i planned it to work too
2020-07-25T18:14:47 < zyp> and the number of digits detection is not gonna work like you planned either
2020-07-25T18:14:54 < Mangy_Dog> i just forgot when trying to run it the way i was
2020-07-25T18:15:03 < Mangy_Dog> why not?
2020-07-25T18:15:24 < zyp> same reason, you don't know if FB comes from digit 1 or digit 15
2020-07-25T18:15:32 < Mangy_Dog> yeah i would
2020-07-25T18:15:34 < zyp> how?
2020-07-25T18:15:51 < Mangy_Dog> Shift 00000001 first... then shift 0000 0000 untill the IO goes down
2020-07-25T18:15:57 < Mangy_Dog> count how many times i shifted
2020-07-25T18:16:07 < Mangy_Dog> till it went down
2020-07-25T18:16:15 < zyp> it will never go up
2020-07-25T18:16:29 < zyp> because you have 15 digits that are all trying to drive it at the same time
2020-07-25T18:16:33 < Mangy_Dog> row D is set high on the first bit
2020-07-25T18:16:36 < Mangy_Dog> shift
2020-07-25T18:17:20 < Mangy_Dog> it would stay high once the shift goes beyownd the last reg
2020-07-25T18:17:30 < zyp> nope
2020-07-25T18:17:55 < zyp> you shift out 00000001, first digit tries to drive FB high, but digit 2-15 are still forcing it low, and they are stronger, like you just learned
2020-07-25T18:19:59 < zyp> as long as you have multiple drivers all in parallel and they are not all driving the same way, what you get depends on which side is stronger
2020-07-25T18:20:40 < zyp> and how strong each is might vary, so you can't really rely on that either

2020-07-25T18:21:53 < zyp> so anyway, I have a suggestion for a design revision: disconnect FB from the row D select, and instead add a solder jumper between FB and D-OUT
2020-07-25T18:21:54 < MangyDog> likely to go again storm right over here
2020-07-25T18:22:02 < MangyDog> knoking out phone 
2020-07-25T18:22:07 < zyp> on the last digit connect FB to D-OUT
2020-07-25T18:22:24 < zyp> solder jumper means you get it only from the last
2020-07-25T18:22:34 < MangyDog> did you see my post wher ei explained how FB worked?
2020-07-25T18:22:49 < zyp> not sure
2020-07-25T18:23:08 < zyp> did you see where I explained how it wouldn't work?
2020-07-25T18:23:14 < zyp> 17:17:54 < zyp> you shift out 00000001, first digit tries to drive FB high, but digit 2-15 are still forcing it low, and they are stronger, like you just learned
2020-07-25T18:23:18 < zyp> 17:19:59 < zyp> as long as you have multiple drivers all in parallel and they are not all driving the same way, what you get depends on which side is stronger

2020-07-25T18:26:01 < MangyDog> So when a reg pin is 0 its sinked to ground?
2020-07-25T18:26:05 < MangyDog> not just not powered?
2020-07-25T18:28:41 < zyp> yes
2020-07-25T18:30:15 < zyp> otherwise your transistors wouldn't turn off :)
2020-07-25T18:30:39 < MangyDog> good point
2020-07-25T18:30:59 < zyp> the gate of a FET is effectively a capacitor, if you just stopped powering it it would retain the charge and remain on
2020-07-25T18:31:10 < MangyDog> nods
2020-07-25T18:31:30 < MangyDog> oh well
2020-07-25T18:31:39 < MangyDog> no FB pin
2020-07-25T18:31:46 < MangyDog> seemed like a good idea at the time
2020-07-25T18:32:07 < zyp> next design revision, make a solder jumper to loop D-OUT back into FB on the last digit
2020-07-25T18:32:20 < zyp> and only solder that on the last digit
2020-07-25T18:32:39 < MangyDog> that kinda breaks the daisy chian idea
2020-07-25T18:32:49 < MangyDog> but Dout is already there
2020-07-25T18:32:54 < zyp> no, it doesn't
2020-07-25T18:32:57 < MangyDog> thats hwo you pass to the next digit
2020-07-25T18:34:52 < zyp> https://bin.jvnv.net/file/XpcQs.jpg
2020-07-25T18:35:25 < zyp> in other words, let FB just remain a pass through on all boards except the last, where it loops D-OUT back
2020-07-25T18:36:09 < MangyDog> ahh fair enough
2020-07-25T18:36:16 < MangyDog> ill include that when i release the files online
2020-07-25T18:36:23 < MangyDog> i wont bother making a new set myself though
2020-07-25T18:36:35 < zyp> no need as long as you know the length :)
2020-07-25T18:36:44 < MangyDog> true
2020-07-25T18:36:48 < MangyDog> it was just a silly idea anyway
2020-07-25T18:36:54 < zyp> but I suggest you unsolder the FB links between the boards you've got
2020-07-25T18:36:59 < MangyDog> like pointless lazy saving exasize
2020-07-25T18:37:05 < MangyDog> yeah about to
2020-07-25T18:37:13 < MangyDog> as i fix the 2 mosfets that arent working
2020-07-25T18:37:25 < dongs> whats the topic
2020-07-25T18:37:33 < dongs> did mangy's shit fail
2020-07-25T18:37:37 < dongs> has he posted a schematic

2020-07-25T18:38:27 < dongs> ah, hes doing same shit im doing but hes doing it wrong
2020-07-25T18:38:43 < zyp> haha
2020-07-25T18:38:51 < dongs> what you use is you use the chink 16bit led driver not this weird 8bit trash
2020-07-25T18:39:02 < zyp> I already suggested a 16-bit shift register :)
2020-07-25T18:39:07 < dongs> then you put pfets/pnp on high bits to switch rows and you have 8 bits of columns or wahtever
2020-07-25T18:39:26 < dongs> he could also use one of those TM1688 things
2020-07-25T18:39:28 < zyp> no need for matrix switching if you use a 16-bit shift register
2020-07-25T18:39:32 < dongs> that are basically i2c matrix driver
2020-07-25T18:39:33 < MangyDog> like i said i couldnt fit them in the design
2020-07-25T18:41:25 < dongs> why you coudln't 'fit'?
2020-07-25T18:41:33 < dongs> do you have that shift register behind every fucking digit?
2020-07-25T18:41:34 < MangyDog> these digits are small
2020-07-25T18:41:42 < MangyDog> yes
2020-07-25T18:41:44 < dongs> christ.
2020-07-25T18:41:52 < zyp> dongs, each digit is a 10x15mm pcb or something like that
2020-07-25T18:42:06 < MangyDog> 10x20
2020-07-25T18:42:08 < dongs> https://www.sunrom.com/p/tm1668-soic24-led-displaykeypad-driver this is what you should have used
2020-07-25T18:42:17 < dongs> (well, or a bigger pin version of that)
2020-07-25T18:42:20 < dongs> 1 chip would drive ALL your leds.
2020-07-25T18:42:55 < zyp> sounds fun to route
2020-07-25T18:43:26 < dongs> how so? route all cathodes/anodes together and just via up to the led pins

2020-07-25T18:58:40 < dongs> that looks disgusting
2020-07-25T18:59:05 < dongs> zyp, why wouldnt you just use 2 shift registers for the fets
2020-07-25T18:59:18 < dongs> i mean led drivers
2020-07-25T18:59:25 < dongs> so you can just chain them and control them from same line
2020-07-25T19:01:05 < zyp> what do you mean?
2020-07-25T19:08:01 < dongs> instead of using HC164
2020-07-25T19:08:13 < dongs> you daisychain DIN->DOUT to a 2nd MAX thing
2020-07-25T19:08:19 < dongs> and just drive fet gates from that
2020-07-25T19:08:22 < dongs> for the highside
2020-07-25T19:08:32 < dongs> then you just clock out one set of shit over SPI
2020-07-25T19:09:09 < zyp> i.e. double the number of bits to shift to save one signal?
2020-07-25T19:09:25 < dongs> what waht the fuck does HC164 do
2020-07-25T19:09:31 < zyp> it's a shift register
2020-07-25T19:09:42 < dongs> ah serial in right but so how does that double it?
2020-07-25T19:10:10 < dongs> you have 16 bits of column control right?
2020-07-25T19:10:10 < zyp> you're suggesting I shift 16 col values and 16 row selects on the same line, right?
2020-07-25T19:10:13 < dongs> yes
2020-07-25T19:10:23 < zyp> instead of only the 16 col values
2020-07-25T19:10:29 < zyp> 16+16 is double of 16
2020-07-25T19:10:42 < dongs> yeah but now you have to clock out cols separately?
2020-07-25T19:11:24 < zyp> shift register clock is tied to led driver latch
2020-07-25T19:11:51 < zyp> so the row select is automatically advanced by one every time the led driver latches a new row worth of values
2020-07-25T19:12:54 < zyp> all I have to do is shift in a 1 for the first row, then it advances automatically for the rest of the frame

2020-07-25T20:02:52 < R2COM1> the memory should be allocated from heap which is defined
2020-07-25T20:02:53 < R2COM1> or
2020-07-25T20:02:56 < zyp> assuming you have a heap, sure
2020-07-25T20:03:44 < zyp> not sure if you have to define them yourself or there is a default implementation that builds on malloc/free
2020-07-25T20:06:27 < R2COM1> you mean define in linker script right
2020-07-25T20:06:32 < R2COM1>   . = ALIGN(4);

2020-07-25T20:07:21 < MangyDog> this is fun. removed those feed back jumpers//// managed to pull up the pad on that first digit, replaced the digit with one spare i had...
2020-07-25T20:07:25 < MangyDog> and now nothing
2020-07-25T20:07:28 < MangyDog> i cant get anything to showu p
2020-07-25T20:07:39 < MangyDog> checked continuity
2020-07-25T20:07:48 < MangyDog> ir all seems correct
2020-07-25T20:08:12 < veverak> R2COM1: well, I believe it should be avoided unless necessary
2020-07-25T20:08:24 < veverak> R2COM1: and there is difference between 'just new' and placement new
2020-07-25T20:08:27 < veverak> the second is necessary
2020-07-25T20:09:19 < zyp> R2COM1, well, there's several layers
2020-07-25T20:09:56 < zyp> you need an operator new that calls malloc to allocate stuff
2020-07-25T20:10:14 -!- R2COM1 is now known as R2COM
2020-07-25T20:10:18 < zyp> then you need the malloc, newlib provides one that uses sbrk to get memory to allocate from
2020-07-25T20:10:35 < R2COM> ah right
2020-07-25T20:10:35 < veverak> which is not true for placement new version
2020-07-25T20:10:40 < zyp> and then you need a sbrk to provide that memory, and it gets told where to provide memory from by the linker script
2020-07-25T20:10:48 < R2COM> i basically need to have implementation for "new" as well
2020-07-25T20:11:07 < zyp> yeah, unless you already do
2020-07-25T20:11:18 < veverak> hmm, I wonder
2020-07-25T20:11:39 < veverak> I think there is implementation of 'new' that allows only placement new, ie, it cames without the dynamic allocation and call to malloc
2020-07-25T20:11:49 < veverak> can't remember where
2020-07-25T20:11:51 < R2COM> wait but if one forgets about embedded and just uses gcc , for "new" and "delete" which files included
2020-07-25T20:11:54 < zyp> newlib libc provides malloc, libnosys provides sbrk, so if you're using that you got two of the pieces
2020-07-25T20:12:17 < zyp> and then you need an operator new which is probably provided by libc++ or whatever it's called
2020-07-25T20:12:26 < zyp> but I haven't used it on embedded so I'm not sure
2020-07-25T20:13:03 < R2COM> so arm-none-eabi-g++ doesnt come with all necessary stuff for new and delete?
2020-07-25T20:13:18 < veverak> jsut test it yourself
2020-07-25T20:13:23 < zyp> it probably does, I just haven't tried :)
2020-07-25T20:15:39 < veverak> damn it
2020-07-25T20:15:52 < veverak> can't find the operator new only in placement version
2020-07-25T20:16:06 < veverak> (which is usefull, as it does not drag the dynamic part of the code with itself)

2020-07-25T20:40:44 < MangyDog> well thats a bit load of wtf
2020-07-25T20:40:48 < MangyDog> i think this mcu is borked
2020-07-25T20:43:42 < dongs> R2COMmie why are you using gcc, the fucking evil shit compiler
2020-07-25T20:47:50 < catphish> because it's best compiler
2020-07-25T20:49:03 < strata> <MaoZedongs> clang is best
2020-07-25T20:53:40 < emeb> the best compiler is the one you're using right now.
2020-07-25T20:57:33 < jadew> any ideas on how to calibrate PT100 sensors?
2020-07-25T20:57:49 < jadew> the one I have in front of me seems to have a 2 ohm offset @ 0 °C
2020-07-25T20:58:04 < jadew> and I'm not sure if it's the wires or the thermal coefficient
2020-07-25T20:58:49 < MangyDog> honestly.. i didnt think you could calibrate it that accurately
2020-07-25T20:59:08 < MangyDog> 2c isnt a bad margin for error on a pt100 id have thought 
2020-07-25T20:59:35 < jadew> well, I could do it at 100 °C too and see what I get, I suppose I could get the coefficient from that and forget the about the offset
2020-07-25T20:59:46 < jadew> MangyDog, 2 Ω
2020-07-25T20:59:51 < jadew> that's like 6 
2020-07-25T20:59:55 < jadew> that's like 6 °C
2020-07-25T21:00:15 < MangyDog> oh
2020-07-25T21:00:21 < jadew> time to get something boiling
2020-07-25T21:05:08 < qyx> last time I read something about doing your own 0°C reference
2020-07-25T21:05:18 < qyx> or 0.01°C or what exactly it is
2020-07-25T21:05:28 < jadew> me?
2020-07-25T21:05:33 < jadew> I don't think it was me
2020-07-25T21:05:41 < qyx> no, on the interwebs
2020-07-25T21:07:08 < qyx> I don't remember how is that thing called
2020-07-25T21:07:19 < qyx> it is a glass tube with something and something and water and vacuum
2020-07-25T21:07:36 < qyx> you do something with it, then freeze, then something and then it stabilizes at 0°C
2020-07-25T21:07:59 < jadew> eh, I don't need that precise of a 0 °C
2020-07-25T21:08:17 < zyp> ice slush water should give you a pretty precise 0 degrees
2020-07-25T21:08:27 < jadew> yep, that's what I did
2020-07-25T21:08:38 < zyp> same with boiling water for 100 degrees
2020-07-25T21:08:44 < jadew> crushed a bunch of ice cubes and waited for water to form
2020-07-25T21:10:10 < jadew> problem is I don't want to do the next step into the kitchen (100 °C one)
2020-07-25T21:10:44 < jadew> I have a tip thermometer, I wonder how precise that is
2020-07-25T21:11:16 < zyp> get a portable induction cooktop
2020-07-25T21:11:24 < qyx> put a bulb into a water?
2020-07-25T21:11:41 < jadew> qyx, won't it crack?
2020-07-25T21:11:51 < jadew> but I guess I could just use some wire
2020-07-25T21:12:06 < qyx> I would say no, should it?
2020-07-25T21:12:07 < Ultrasauce> no electric kettle?
2020-07-25T21:12:10 < jadew> (I do have an alcohol burner, but no support to keep something on top of it)
2020-07-25T21:12:21 < jadew> Ultrasauce, I could improvise one
2020-07-25T21:12:31 < jadew> I have a 40 A power supply, that should do it
2020-07-25T21:12:41 < Ultrasauce> spend 4 bucks at a thrift store...
2020-07-25T21:12:56 < zyp> Ultrasauce, I forget that's a thing :)
2020-07-25T21:13:39 < qyx> so thats for ľ point calib
2020-07-25T21:13:44 < qyx> but how to do a š point one?
2020-07-25T21:13:49 < qyx> meh
2020-07-25T21:14:00 < qyx> ľ=2, š=3
2020-07-25T21:14:22 < jadew> you need 3 points to get the curve or what's that about?
2020-07-25T21:14:36 < qyx> PT100 should be pretty linear
2020-07-25T21:14:49 < zyp> I have an electric thermopot that always has water ready at 90C and a plain kettle that I throw on the induction cooktop if I need to boil up some water in a hurry
2020-07-25T21:15:06 < zyp> and also a portable induction cooktop if I have to do that somewhere else than the kitchen
2020-07-25T21:16:22 < jadew> I should probably get one of those too, sounds useful
2020-07-25T21:16:30 < jadew> can you hit PCBs with it?
2020-07-25T21:16:34 < jadew> *heat
2020-07-25T21:16:54 < zyp> directly? probably not a good idea
2020-07-25T21:17:15 < jadew> why not?
2020-07-25T21:17:17 < qyx> with a induction?
2020-07-25T21:17:19 < jadew> (I never used one)
2020-07-25T21:17:21 < jadew> yeah
2020-07-25T21:17:37 < qyx> won't your traces sublime?
2020-07-25T21:18:16 < zyp> an induction cooktop is essentially a big coil with some power electronics to drive it
2020-07-25T21:18:31 < MangyDog> ok this is really insane.... this esp8266 is now basically crashing on start up.. but only when its wired to teh shift reg. i even tried uploading a near empty program. Only a serial print hello.... and i get garbled mess and just once. unsolder everything and it behaves... its as if the feed back pin i had before was doing something to stablise the esp!
2020-07-25T21:18:33 < zyp> it doesn't get hot itself (apart from waste heat)
2020-07-25T21:18:40 < qyx> idk if it works, alu pot doesn't work
2020-07-25T21:18:49 < jadew> right, but 1) would it work? and 2) would it create that big of a potential difference in traces?
2020-07-25T21:18:56 < zyp> it heats whatever you put on top of it by inducing currents in it
2020-07-25T21:19:10 < qyx> why doesn't it work with all materials then?
2020-07-25T21:19:19 < qyx> *all materials able to carry current
2020-07-25T21:19:32 < jadew> aluminium is too good of a conductor :P
2020-07-25T21:19:44 < jadew>  /troll
2020-07-25T21:19:54 < zyp> no, it's true
2020-07-25T21:20:04 < jadew> oh, really?
2020-07-25T21:20:09 < jadew> so it wouldn't work with copper either?
2020-07-25T21:20:14 < qyx> if thats the case, then copper would not work neither
2020-07-25T21:20:15 < zyp> wikipedia states «If the metal is too thin, or does not provide enough resistance to current flow, heating will not be effective.»
2020-07-25T21:20:29 < jadew> interesting
2020-07-25T21:20:40 < zyp> «Most induction tops will not heat copper or aluminum vessels because the magnetic field cannot produce a concentrated current; "all metal" induction tops use much higher frequencies to overcome that effect.»
2020-07-25T21:20:42 < jadew> at least the resistors would reflow
2020-07-25T21:21:07 < zyp> didn't know there were such a thing as «all metal induction cooktops»
2020-07-25T21:21:20 < jadew> interesting
2020-07-25T21:21:53 < jadew> HAM operators, turn your rigs off. I'm cooking for the next 30 minutes.
2020-07-25T21:22:20 < zyp> but still, a pcb wouldn't be an even surface, you'd probably get weird hotspots while other areas remains cold
2020-07-25T21:22:38 < jadew> probably
2020-07-25T21:22:50 < jadew> someone must have tried it
2020-07-25T21:23:10 < zyp> what sort of stove do you have in the kitchen btw? gas?
2020-07-25T21:23:14 < Ultrasauce> sounds only slightly less destructive than soldering with an arc welder
2020-07-25T21:23:19 < jadew> zyp, yeah
2020-07-25T21:23:59 < zyp> not really a thing in norway (since we don't have a gas grid)
2020-07-25T21:24:28 < jadew> fairly common here
2020-07-25T21:24:31 < zyp> it's all electric, either old resistance heaters or modern induction
2020-07-25T21:24:32 < jadew> the oven is electric tho
2020-07-25T21:24:50 < jadew> you can control it much better
2020-07-25T21:24:57 < jadew> but that's not a problem for the stove
2020-07-25T21:25:04 < zyp> control what?
2020-07-25T21:25:12 < jadew> heat
2020-07-25T21:25:18 < zyp> electric, you mean?
2020-07-25T21:25:22 < jadew> yeah
2020-07-25T21:25:27 < jadew> for the oven
2020-07-25T21:25:32 < zyp> easier to program, I guess
2020-07-25T21:25:41 < qyx> yeah gas ovens were pain
2020-07-25T21:25:43 < zyp> electromechanical gas valves sounds like a hassle
2020-07-25T21:25:49 < qyx> the old ones
2020-07-25T21:25:52 < jadew> yeah, you know that if you set it to 160 for X minutes, you'll get your food like this
2020-07-25T21:26:03 < jadew> with a gas oven you have to guess the temperature
2020-07-25T21:26:15 < qyx> set it to, uh, oh, to the middle!
2020-07-25T21:26:23 < jadew> yeah :)
2020-07-25T21:26:26 < jadew> and each one is different
2020-07-25T21:26:32 < zyp> camping trailers have gas stoves and gas ovens though
2020-07-25T21:26:34 < qyx> and burn your fingers first
2020-07-25T21:26:51 < zyp> since it's easier to bring around a propane tank than enough electricity :)
2020-07-25T21:27:48 < qyx> we have bought a lpg cooktop too
2020-07-25T21:27:53 < qyx> atm we are using an induction one
2020-07-25T21:28:18 < qyx> but it is summer, I wonder how much electricity will be available in the winter
2020-07-25T21:28:35 < zyp> you're offgrid, right?
2020-07-25T21:28:37 < qyx> I read some wind turbine reviews and it seems it is not the right way
2020-07-25T21:28:41 < qyx> yeah, first month
2020-07-25T21:28:56 < zyp> fun
2020-07-25T21:29:16 < qyx> I need to change some habits
2020-07-25T21:29:27 < qyx> like watering the garden in the morning instead of the evening
2020-07-25T21:30:12 < qyx> and replace my kitchen server with something less power hungry
2020-07-25T21:30:26 < zyp> aww
2020-07-25T21:31:00 < qyx> also https://i.imgur.com/nODAf1Y.png
2020-07-25T21:32:12 < qyx> to control exterior window shaders
2020-07-25T21:32:14 < zyp> speaking of servers, I keep thinking about this silly idea of making ghetto bladeservers
2020-07-25T21:33:07 < zyp> like making a card that'll host four RK3399-SOM with an ethernet switch with SGMII uplink
2020-07-25T21:33:27 < zyp> then stick 16 of those and a switch card in a subrack, for 64 nodes in 3U
2020-07-25T21:33:46  * qyx likes
2020-07-25T21:34:37 < zyp> would make for a cool cluster, and fun to make, but it would also be utterly pointless
2020-07-25T21:35:31 < zyp> I also wonder how good RK3399 is
2020-07-25T21:35:57 < zyp> on paper it seems decent, but I wouldn't be surprised if there's a bunch of issues in practice
2020-07-25T21:36:17 < qyx> oh zyp I have a photo for you
2020-07-25T21:37:11 < qyx> https://bin.jvnv.net/file/o1Vi4.JPG
2020-07-25T21:45:38 < zyp> what am I looking at?
2020-07-25T21:45:52 < qyx> basement with a rock
2020-07-25T21:46:09 < zyp> ah, welcome to the club?
2020-07-25T21:46:22 < zyp> I mean, I neither have basements nor rocks now, but still
2020-07-25T22:10:13 < MangyDog> zyp found the issue causing my esp to crash
2020-07-25T22:12:46 < MangyDog> the PWm IO was driving the mosfet directly.... though im not really sure why it would, but i guess there was some kinda 5v feedback off the gate that caused the cpu to crash
2020-07-25T22:12:59 < MangyDog> looking online the esp isnt 5v tolorant even though the datasheet says it is
2020-07-25T22:13:17 < MangyDog> i guess its a safety feature to hault the mcu
2020-07-25T22:13:29 < MangyDog> still not sure how i get a 5v feedback off a mosfet gate though
2020-07-25T22:16:30 < qyx> feedback from the gate?
2020-07-25T22:16:31 < MangyDog> fixed it by trying a few different resistors first a 10k was toos trong 1k to weak didnt have any 5ks but 4.7 seems to have done the trick
2020-07-25T22:16:41 < MangyDog> qyx i know i didnt think it was possible
2020-07-25T22:16:53 < MangyDog> but something coming back off that gate to the io caused the mcu to crash
2020-07-25T22:17:36 < MangyDog> ive not used esp's before sooooo i guess theyre more finiky than usual

2020-07-26T00:04:23 < zyp> I've been doing that for a couple of years now
2020-07-26T00:05:01 < mawk> my phone is rooted so it always has been pretty hard to pay with the phone
2020-07-26T00:05:07 < mawk> but this bank bunq thing doesn't even check for root status
2020-07-26T00:05:14 < zyp> ah
2020-07-26T00:05:29 < zyp> I don't bother with rooting my phone
2020-07-26T00:05:33 < mawk> and NL banks forbid google pay for some reason also, but they allow apple pay
2020-07-26T00:05:50 < mawk> I root for real backups, and to have kernel wireguard vpn
2020-07-26T00:07:21 < zyp> eh, fuck that, I don't have anything important on my phone that isn't cloud synced already and I don't do anything that would benefit from a vpn

2020-07-26T13:09:10 < Mangy_Dog> Morning all, I need some advice and help figuring out how and if i should drive my digit display using hardware SPI and DMA? The display is daisychainged 595 shift regs. Im assuming SPI clock and data polarity is the same?  The main reason for this idea is not so much for faster data throughput, I think ie already hit the limits on what the shiftregs can take with bitbanging. But more to do 
2020-07-26T13:09:10 < Mangy_Dog> with having access to none blocking hardware and buffer. So I can drive the display without other code slowing down the shift reg display update... What are youre thoughts? And ive never done DMA before kinda need a little guidence.

2020-07-26T13:33:38 < t4nk_freenode> lol Mangy_Dog ... I was just teasing ;)
2020-07-26T13:33:54 < Mangy_Dog> its ok my spelling is shoddy at the best of times
2020-07-26T13:34:07 < Mangy_Dog> ive only woken up and had 1 coffee and feeling pretty tierd still
2020-07-26T13:34:26 < t4nk_freenode> being a non-native speaker.. I'm often scared to death of what I write and how I express it
2020-07-26T13:34:38 < t4nk_freenode> that's way worse ;)
2020-07-26T13:34:48 < Mangy_Dog> :p
2020-07-26T13:40:04 < t4nk_freenode> haven't used dma myself either, currently looking at some vga code that uses it
2020-07-26T13:40:19 < t4nk_freenode> then maybe I'll learn a bit more about it
2020-07-26T13:40:41 < Mangy_Dog> nods
2020-07-26T13:41:57 < Mangy_Dog> the concept is i want to make a set buffer thats the data to be sent to my string of shift regs.... and the dma controller i guess through spi just cycles that buffer over and over and over keeping the display showing that data... And all i have to do in code is periodically update the data in the buffer if i wanted to change whats being displayed
2020-07-26T13:42:34 < t4nk_freenode> but I already did learn that it's important to look at that clock-tree that came up.... to see how the dma channels are connected to the matrix
2020-07-26T13:42:54 < Mangy_Dog> clock tree?
2020-07-26T13:43:40 < t4nk_freenode> "the AHB bus matrix diagram"
2020-07-26T13:44:20 < Mangy_Dog> ah
2020-07-26T13:44:31 < t4nk_freenode> I'm looking at f407 myself, in the matrix you can see which paths are possible
2020-07-26T13:44:37 < Mangy_Dog> nodnods
2020-07-26T13:44:41 < Mangy_Dog> in my case im using esp
2020-07-26T13:44:45 < Mangy_Dog> 8266
2020-07-26T13:45:16 < t4nk_freenode> ah yea, I'm in that chan too
2020-07-26T13:45:35 < t4nk_freenode> got a couple of eps32's myself now
2020-07-26T13:45:38 < Jak_o_Shadows> I've been thinking about getting one or more of them
2020-07-26T13:46:07 < Mangy_Dog> i kinda had to i need network access for this project :p
2020-07-26T13:46:09 < Jak_o_Shadows> It's that or a bunch of other wireless module things
2020-07-26T13:47:56 < t4nk_freenode> those esp32's are quite handy, not too expensive, dual core, lots of mem, lots of speed, wifi and bt
2020-07-26T13:48:22 < t4nk_freenode> I'm just a little disappointed in gpio speed
2020-07-26T13:48:59 < t4nk_freenode> but that's ok if you just use them as a handy network component
2020-07-26T13:49:03 < Jak_o_Shadows> My use case (computer controlled christmas lights) doesn't need that much
2020-07-26T13:50:13 < t4nk_freenode> they can't say you didn't start working on your x-mas presents on time then
2020-07-26T13:50:43 < Jak_o_Shadows> Yeah, i'm thinking about picking up that project again

2020-07-26T15:16:28 < Laurenceb> hmf my washing machine is fuxored
2020-07-26T15:16:47 < Laurenceb> looks like a big design flaw, they didnt consider than the motor is inductive
2020-07-26T15:16:48 < Steffanx> OK.
2020-07-26T15:17:01 < Laurenceb> it turned into a spot welder
2020-07-26T15:17:31 < GenTooMan> coil shorted?
2020-07-26T15:17:48 < Steffanx> Ofcourse they considered it... but the hardware has to be cheap
2020-07-26T15:17:48 < Laurenceb> looks like a brush wore out
2020-07-26T15:18:05 < Laurenceb> this caused arcing that then acted as a triggered spark gap
2020-07-26T15:18:26 < Laurenceb> then the inductance turned the side of the brush into an arc welder
2020-07-26T15:18:49 < Steffanx> Better start a gofundme Laurenceb 
2020-07-26T15:19:18 < Laurenceb> the protection fuse thingy (15AM253) opened but that also arced out and self destructed as its only rated to 5A inductive
2020-07-26T15:19:25 < Laurenceb> and blows at 10A wtf
2020-07-26T15:20:01 < Laurenceb> I've ordered new brushes but I want to make a protection circuit that actually works this time
2020-07-26T15:20:11 < Steffanx> It was a very selective lightning strike
2020-07-26T15:20:23 < Laurenceb> it was just the brush wearing out
2020-07-26T15:20:34 < Laurenceb> triggered spark gap effect
2020-07-26T15:20:52 < Steffanx> Thats no fun
2020-07-26T15:21:14 < Steffanx> Have to make a big story out of it. 
2020-07-26T15:21:18 < Laurenceb> I was thinking of using a polyfuse
2020-07-26T15:21:29 < GenTooMan> arcing brushes can cause the holders to deform and possibly cause a fire.
2020-07-26T15:21:32 < Laurenceb> but they are quite slow to blow 
2020-07-26T15:21:51 < Laurenceb> GenTooMan: yeah it needs thermal and overcurrent protection
2020-07-26T15:21:55 < Laurenceb> this is not simple
2020-07-26T15:22:51 < GenTooMan> yeah not for a motor, at least the fuse blew ... eventually. 1200W rating for the fuse? (240V 5A)
2020-07-26T15:23:10 < PaulFertser> Laurenceb: how long was it in service?
2020-07-26T15:23:12 < Laurenceb> maybe I'll solder a discrete circuit breaker unit onto the main pcb
2020-07-26T15:23:20 < Laurenceb> PaulFertser: 24 years
2020-07-26T15:23:34 < Steffanx> Lol.
2020-07-26T15:23:45 < PaulFertser> Laurenceb: impressive! Any other repairs performed during all the years?
2020-07-26T15:24:00 < Steffanx> It even washed Laurenceb's diapers
2020-07-26T15:24:04 < Laurenceb> PaulFertser: yeah loads, new belts, seals etc
2020-07-26T15:24:19 < Laurenceb> this time I let the brushes run too low :(
2020-07-26T15:24:41 < PaulFertser> Laurenceb: I had to add an additional seal for the tank perimeter cut from a push bike tube :)
2020-07-26T15:25:02 < Laurenceb> seems like I uncovered a big design flaw with the motor protection
2020-07-26T15:25:26 < Laurenceb> 15AM253A is not very suitable for inductive loads
2020-07-26T15:25:37 < PaulFertser> Laurenceb: the belt is still ok but I'm not sure what to do once it worns out since it has a special shape to work in CVT.
2020-07-26T15:25:46 < Laurenceb> guess I could add snubber capacitors
2020-07-26T15:26:19 < PaulFertser> Laurenceb: it's likely you'll face something else long before your new brushes wear.
2020-07-26T15:26:21 < Laurenceb> so discrete 10A circuit braker or maybe a quick blow fuse on the main pcb
2020-07-26T15:26:37 < Laurenceb> then thermal fuse and another snubber cap inside the motor head
2020-07-26T15:26:39 < Steffanx> Is it a design flaw or... should you have done maintenance a looooong time ago? 
2020-07-26T15:26:58 < Steffanx> Perhaps a well calculated design flaw
2020-07-26T15:27:05 < Laurenceb> Steffanx: for CE the motor should be able to handle worn brushes without turning into a spot welder
2020-07-26T15:27:16 < Steffanx> CE. What brand is this?
2020-07-26T15:27:24 < Laurenceb> Bosch
2020-07-26T15:27:54 < GenTooMan> a motor start current is considered 5X the continuous current. So if it draws 1A normally it will on start up draw 5A much like an incandescent lamp
2020-07-26T15:28:23 < Laurenceb> GenTooMan: even tho it has a control unit?
2020-07-26T15:28:45 < GenTooMan> the control unit had a 5A fuse on it? or the motor?
2020-07-26T15:28:50 < Laurenceb> some sort of triac based thing
2020-07-26T15:29:09 < PaulFertser> How do you even detect worn brushes before it's too late?
2020-07-26T15:29:26 < Laurenceb> PaulFertser: dismantle and check, they last ~10 years
2020-07-26T15:29:47 < PaulFertser> Heh, it's easy to forget something that needs to be done so rarely.
2020-07-26T15:30:13 < Laurenceb> I'm just obsessed with rebuilding this thing so its actually safe this time...
2020-07-26T15:30:46 < Laurenceb> clearly Bosch engineers didnt actually check what happened when brushes wose out, as they didnt want to run it 24/7 for >1 year in the lab
2020-07-26T15:31:35 < PaulFertser> I have an electric coffee grinder that's older than me. But it's really much worse than a modern chinese one. Probably old appliances are really not worth sticking to...
2020-07-26T15:32:58 < PaulFertser> Laurenceb: do you think anything specific should be done to the washing machine bearings at regular intervals too?
2020-07-26T15:33:19 < GenTooMan> what you mean maintenance? :D
2020-07-26T15:33:53 < Laurenceb> PaulFertser: I'm not sure, prob depends on the brand
2020-07-26T15:34:07 < Laurenceb> some last for decades, some for ~5 years
2020-07-26T15:36:57 < sync> Laurenceb: it's common that if the brushes go too low everything is fucked
2020-07-26T15:37:18 < Laurenceb> sync: yeah I've been reading on white goods forums
2020-07-26T15:37:23 < Laurenceb> but it shouldnt be
2020-07-26T15:37:32 < Laurenceb> with proper protection it should be managable
2020-07-26T15:38:59 < Laurenceb> I guess its a "feature" as customer has to buy a new machine
2020-07-26T15:39:07 < Laurenceb> if their house hasnt been burnt down...
2020-07-26T15:41:51 < Laurenceb> maybe a varistor will do the job

2020-07-26T15:50:13 < GenTooMan> well I have an idea how the system was being controlled, however just suppressing noise caused by a situation from lack of maintenance is a bit like ignoring an indicator on a nuclear reactor.
2020-07-26T15:52:12 < Laurenceb> hmf why are fuse voltage ratings so low
2020-07-26T15:52:19 < Laurenceb> >20mm long 250VAC fuses
2020-07-26T15:52:21 < Laurenceb> wtf
2020-07-26T15:52:48 < Laurenceb> a 20mm long arc at 250V sound unfeasible
2020-07-26T15:53:34 < GenTooMan> uh the fuse isn't allowed to catch fire.. so it is designed to melt and diffuse safely inside the body of the fuse.
2020-07-26T15:54:02 < Laurenceb> sure
2020-07-26T15:54:17 < GenTooMan> it needs space to do that.
2020-07-26T15:54:39 < Laurenceb> oh the fuse will explode?
2020-07-26T15:54:46 < Laurenceb> that makes sense I guess
2020-07-26T15:55:09 < Laurenceb> yeah thats a lot of vapourise dmetal
2020-07-26T15:56:03 < Laurenceb> hmm I'm not seeing how the arc welder effect is going to take place across a fuse tbh
2020-07-26T15:57:19 < Laurenceb> so I'll just stick a fuse holder on the main pcb then thermal fuse and varistor inside the motor
2020-07-26T15:57:44 < GenTooMan> is the control board dead?
2020-07-26T15:58:05 < Laurenceb> nope its all fine
2020-07-26T15:58:17 < Laurenceb> triac i ont he ground side so wasnt effects
2020-07-26T15:58:24 < Laurenceb> *effected
2020-07-26T15:59:24 < GenTooMan> I assume you've checked for shorts et al.
2020-07-26T15:59:48 < Laurenceb> yeah
2020-07-26T16:00:31 < Laurenceb> just have to size the varistor so it can absorp the inductive load from the motor
2020-07-26T16:00:42 < sync> Laurenceb: nobody cares
2020-07-26T16:00:48 < sync> it just lasts long enough anyway
2020-07-26T16:01:04 < sync> some stuff has a switch on the brushes that just turn off power
2020-07-26T16:01:57 < Laurenceb> sync: people care when their house burns down
2020-07-26T16:02:04 < sync> it doesn't tho
2020-07-26T16:02:23 < Laurenceb> only the main breaker on my consumer unit saved it
2020-07-26T16:03:26 < Laurenceb> it stinks of box ticking to meed safety standards without actually thinking it thought
2020-07-26T16:03:43 < sync> that is why the breaker is there
2020-07-26T16:03:59 < Laurenceb> lol
2020-07-26T16:04:35 < sync> my tumble dryer and washing machine also have no fuse in them
2020-07-26T16:04:40 < sync> my dish washer also
2020-07-26T16:04:57 < sync> I think that one has a small one infront of the supply for the controls
2020-07-26T16:12:51 < Laurenceb> a varistor to earth would protect the fuse and thermal fuse from arcing
2020-07-26T16:13:02 < Laurenceb> as long as it didnt leak and trigger the rcd
2020-07-26T16:13:41 < GenTooMan> MOV explode when overloaded.
2020-07-26T16:13:51 < GenTooMan> they wear out as well.
2020-07-26T16:14:06 < Laurenceb> maybe not good for safety to connect to earth then
2020-07-26T16:15:09 < Laurenceb> shrug just two of them then, one on main pcb
2020-07-26T16:16:55 < GenTooMan> :D perhaps across the PCB to keep the components on it from expiring.
2020-07-26T16:17:08 < Steffanx> And then your house burns down, they see you messed with your washing machine and... bye whatever insurance?
2020-07-26T16:20:07 < GenTooMan> I think you are fortunate the fuse blew. I've had an alternator brush set wear out on a car. That's ugly you end up replacing the alternator because the holder melted type situation.

2020-07-26T16:56:48 < Steffanx> Your time is tooo valuable 
2020-07-26T16:57:54 < Laurenceb> lol
2020-07-26T16:58:24 < Laurenceb> btfoing the bosch engineers epc style is fun
2020-07-26T16:58:54 < qyx> how is a MOV going to prevent fuse from arcing?
2020-07-26T16:59:27 < Laurenceb> the arcing is initiated by the inductance of the motor coils
2020-07-26T16:59:37 < Laurenceb> its like an arc welder circuit
2020-07-26T16:59:52 < Laurenceb> the MOV dissipates the energy from the motor inductance
2020-07-26T16:59:55 < qyx> when the fuse opens?
2020-07-26T16:59:59 < Laurenceb> yeah
2020-07-26T17:00:14 < qyx> and is the fuse able to maintain the arc at 230VAC?
2020-07-26T17:00:27 < Laurenceb> dunno but I dont want to find out
2020-07-26T17:00:43 < Laurenceb> the stock fuse was , thats what the bosch guys didnt seem to realise
2020-07-26T17:01:35 < qyx> so there are actually two flaws
2020-07-26T17:01:54 < Laurenceb> the motor inductance maintains the arc, each time it dissipates the voltage spikes up
2020-07-26T17:02:27 < Laurenceb> apparently even 50hz ac wasnt enough to stop it
2020-07-26T17:02:38 < Laurenceb> it browned out my whole house for about 2 seconds
2020-07-26T17:03:16 < qyx> you are just overengineering it
2020-07-26T17:03:22 < qyx> replace the fuse with a 22x50 one
2020-07-26T17:04:08 < qyx> *22x58
2020-07-26T17:08:35 < Laurenceb> the stock 15AM253A was interesting - combined current and thermal fuse
2020-07-26T17:08:49 < Laurenceb> but its not designed to cope with very high inductive loads
2020-07-26T17:08:51 < Laurenceb> derp

2020-07-26T18:37:36 < Laurenceb> >muh spiders
2020-07-26T18:37:53 < strata> dude the same shit happened to me like 3 yrs ago
2020-07-26T18:37:57 < strata> 4 years ago now
2020-07-26T18:38:50 < strata> faulty window AC unit burned down rental property. the city pressed criminal charges and put a warrant out for my arrest because the fire dept. broke the sidewalk and i refused to pay the ridiculous "fine" of $15K PER DAY every day *I* didn't fix the CITY's sidewalk. ROFL
2020-07-26T18:40:17 < strata> i went straight up to state attorney's office and they came in and fired like 1/2 of city council
2020-07-26T18:40:25 < Laurenceb> lulwut
2020-07-26T18:41:00 < strata> they also paid to level the property
2020-07-26T18:41:32 < strata> and 2 yrs later insurance eventually paid out the claim after doing everything they could to find proof of arson
2020-07-26T18:42:11 < strata> the tenants had 2 dogs that died in that fire - thank god they weren't home too. they had left for the day
2020-07-26T18:42:28 < strata> it burned the side of the neighbor's house off too lol
2020-07-26T18:42:54 < strata> that's when i got a taste of what rossman had been saying for years
2020-07-26T18:43:22 < strata> insurance is only there to take your money and drop your policy as soon as you need it
2020-07-26T18:43:43 < strata> you gotta fight them tooth and nail and they will straight up try to have you criminally charged to avoid paying if they can
2020-07-26T18:44:28 < strata> the only thing that saved me from not being sent to jail for arson was proof that i was literally 1200 miles away at the time

2020-07-26T20:25:51 < R2COM> is it worth it using virtual functions in cpp in embedded
2020-07-26T20:25:56 < R2COM> wouldnt it be slower
2020-07-26T20:27:08 < jpa-> about as much slower as using a function pointer would be
2020-07-26T20:27:17 < jpa-> so, use them when you need them
2020-07-26T20:28:04 < jpa-> you can also make base classes abstract and child classes final, then the compiler can optimize most virtual function calls
2020-07-26T20:29:33 < jpa-> though in many cases compilers can do that even without manually specifying final

2020-07-27T13:36:31 < Mangy_Dog> i am over weight.....!
2020-07-27T13:36:37 < Mangy_Dog> but why did you mention that?
2020-07-27T13:42:41 < Guest1193> if you're from the usa there's good chance of that >.>
2020-07-27T13:43:30 < t4nk_freenode> I don't think he is ;)
2020-07-27T13:46:18 < t4nk_freenode> at least he does some interesting stuff with his time...
2020-07-27T13:46:31 < t4nk_freenode> instead of the rest of panty-wearing england ;)
2020-07-27T13:46:58 < t4nk_freenode> mmm I mean stockings of course
2020-07-27T13:47:03 < t4nk_freenode> silk.
2020-07-27T13:49:15 < Steffanx> I read your government wants you to lose weight to fight COVID-19 Mangy_Dog 
2020-07-27T13:49:32 < t4nk_freenode> zyp, !!!!!!!!!!! I think my driver card has just been delivered!!!!
2020-07-27T13:49:40 < t4nk_freenode> *crying tears from joy*
2020-07-27T13:49:58 < Steffanx> Shouldn't you be at work or something mr t4nk_freenode ?
2020-07-27T13:50:37 < t4nk_freenode> what makes you think I'm not?
2020-07-27T13:51:38 < Mangy_Dog> steffanx well to be fair loosing weight is good all round
2020-07-27T13:52:49 < Steffanx> You would be so excited nor cry at work, t4nk_freenode 
2020-07-27T13:52:54 < Steffanx> Wouldnt*
2020-07-27T13:52:58 < Steffanx> Lol
2020-07-27T13:52:59 < t4nk_freenode> lol, true
2020-07-27T13:53:23 < t4nk_freenode> cry... maybe, but excitement.. no.
2020-07-27T13:53:24 < Steffanx> Or are you (still) a student?
2020-07-27T13:53:44 < t4nk_freenode> no, Steffanx, I'm well past that
2020-07-27T13:54:05 < Steffanx> Dutch students don't use IRC.
2020-07-27T13:54:38 < t4nk_freenode> I'm even in the age.. where I can't help but notice ... my love handles.. seemlessly transitioning into the rest of my belly :|
2020-07-27T13:54:47 < t4nk_freenode> since we're talking overweight 
2020-07-27T13:56:12 < t4nk_freenode> and if I want to do something about it.. it would have to be within the next few years, or it will NEVER come right again
2020-07-27T13:56:58 < Steffanx> :D
2020-07-27T13:57:20 < Steffanx> Good luck 
2020-07-27T14:04:14 < t4nk_freenode> problem is that I have come to love making my coffee with milk instead of water
2020-07-27T14:04:17 < t4nk_freenode> whole milk too
2020-07-27T14:09:34 < t4nk_freenode> welllllll, cumminnathinkofit.. if I were a professional royal food-taster...
2020-07-27T14:09:36 < qyx> and your belly started expanding?
2020-07-27T14:09:56 < t4nk_freenode> I guess I could be farily excited on a regular basis.. and cry too, even
2020-07-27T14:09:57 < qyx> because of the milk?
2020-07-27T14:11:27 < t4nk_freenode> I read somewhere sometime, that a calf orsth will gain hundreds of times its weight in a few months from the whole milk
2020-07-27T14:11:43 < t4nk_freenode> and that therefore it isn't too great for fully grown entities
2020-07-27T14:28:43 < zyp> t4nk_freenode, that was fast
2020-07-27T14:29:11 < t4nk_freenode> *making nancy-boy voice*
2020-07-27T14:29:14 < t4nk_freenode> I know, right?!

2020-07-27T16:01:03 < Laurenceb> >solar cells are now 5.5c/W
2020-07-27T16:01:07 < Laurenceb> madness
2020-07-27T16:05:09 < Steffanx> Thanks
2020-07-27T16:06:20 < zyp> hmm?
2020-07-27T16:06:46 < englishman> the UK isn't lacking in solar panels, it's lacking sun
2020-07-27T16:06:48 < t4nk_freenode> for the most valuable info I guess
2020-07-27T16:09:29 < Laurenceb> 22.5% efficiency cells at 9.5c/W
2020-07-27T16:09:55 < zyp> just the raw cells, or panels?
2020-07-27T16:10:24 < specing>  before it gets on your roof its more expensive than having a portable gas generator
2020-07-27T16:11:33 < t4nk_freenode> sweet! I think I'll rather buy one of those then :)
2020-07-27T16:12:05 < zyp> specing, well, duh, all the costs with PV are before it gets on the roof
2020-07-27T16:12:16 < specing> last I looked it was 1 euro per W for just the panels, with mounting it was like 2 euro per W
2020-07-27T16:12:39 < zyp> I got quoted 900 NOK plus VAT for 295W panels last year
2020-07-27T16:12:49 < Steffanx> But how do you charge your EV specing?
2020-07-27T16:12:56 < Steffanx> With dirty energy?
2020-07-27T16:12:57 < specing> who cares if you can buy some cells at 5.5cents per W if you walk into some chinese factory and buy a million of them
2020-07-27T16:13:00 < specing> Steffanx: nuclear
2020-07-27T16:13:05 < Steffanx> Hmm
2020-07-27T16:13:29 < Laurenceb> thats raw cells wholesale
2020-07-27T16:13:35 < Steffanx> Have a plant in your backyard specing?
2020-07-27T16:13:44 < Laurenceb> yeah there is huge markup for consumer panels
2020-07-27T16:13:48 < specing> solar cells are dirtier than nuclear (45g CO2 per kW, nuclear is 11g )
2020-07-27T16:14:00 < specing> Steffanx: no, there's one 100km away
2020-07-27T16:14:14 < t4nk_freenode> specing, buy stm32 solarcells! :b
2020-07-27T16:15:27 < specing> zyp: how much to get it installed?
2020-07-27T16:15:28 < zyp> specing, according to my estimates the mounting parts aren't really that expensive, main cost is in panels and inverters
2020-07-27T16:15:48 < specing> zyp: yes, and work (if you hire someone to do it)
2020-07-27T16:16:03 < zyp> yes
2020-07-27T16:16:44 < specing> so its 2 eur before its operational
2020-07-27T16:17:03 < zyp> my estimates doesn't include labor, apart from maybe an electrician for an hour to do some required paperwork
2020-07-27T16:17:06 < zyp> I can do the rest myself
2020-07-27T16:17:20 < specing> I was thinking of a small scale solar setup that powers DC grid only, and feed computers from that
2020-07-27T16:17:55 < zyp> meh, storage costs more than grid-tie
2020-07-27T16:18:00 < specing> no storage
2020-07-27T16:18:05 < specing> no inverters
2020-07-27T16:19:16 < t4nk_freenode> no problem
2020-07-27T16:19:45 < zyp> meh, I figure power electronics cost about the same per watt regardless of whether you've got a grid tie inverter or just DC/DC with MPPT to regulated DC
2020-07-27T16:20:46 < zyp> it's inductors and transistors either way
2020-07-27T16:28:35 < specing> I'm pretty sure that certified grid tie inverters cost lots more
2020-07-27T16:28:55 < specing> and inverters have more transistors than DC/DC
2020-07-27T16:31:58 < Laurenceb> I wonder how inverter cost scales with voltage
2020-07-27T16:34:54 < PaulFertser> lol, stlink updater is in Java but they made it not run on ARM hosts. Sick people.

2020-07-27T17:09:43 < karlp> will assemble next week back at work I guess.
2020-07-27T17:09:45 < qyx> o\ was it a month?
2020-07-27T17:09:54 < qyx> even more
2020-07-27T17:09:58 < karlp> zyp: I'd guess oragne spikes are freezer,
2020-07-27T17:10:07 < karlp> dishwasher/washing machines can be big periodic consumers too
2020-07-27T17:10:45 < karlp> qyx: "departed" my .cz warehouse place in may 4 :)
2020-07-27T17:10:53 < qyx> :D
2020-07-27T17:10:57 < karlp> arrived here last week, but I was out in the countryside
2020-07-27T17:11:06 < qyx> hiking again?
2020-07-27T17:11:17 < karlp> hah
2020-07-27T17:11:19 < karlp> hardly.
2020-07-27T17:11:25 < qyx> were they paddling on a boat with the parcel?
2020-07-27T17:11:25 < karlp> little one didn't like being in the backpack much.
2020-07-27T17:11:54 < Mangy_Dog> quick question, how big is the output buffer of hardware spi in stm32f103?
2020-07-27T17:12:08 < qyx> we bought such backpack too recently, so far he likes it
2020-07-27T17:12:43 < qyx> Mangy_Dog: I would say theres only a shift register
2020-07-27T17:12:53 < zyp> karlp, which spikes? the several amps ones?
2020-07-27T17:13:13 < karlp> yeah
2020-07-27T17:13:24 < karlp> qyx: she loved it younger, she's just getting a bit big for it now.
2020-07-27T17:13:28 < karlp> both of them loved it younger.
2020-07-27T17:13:30 < zyp> karlp, no way
2020-07-27T17:13:41 < karlp> dishwasher/washing machine can do multi amps
2020-07-27T17:13:49 < karlp> freezers unlikly for home freezers yeah
2020-07-27T17:13:59 < karlp> defrost cycles can use more htan you'd think,
2020-07-27T17:14:01 < karlp> but *shrugs*
2020-07-27T17:14:10 < Mangy_Dog> so 1 byte at a time then? Soooo theres no way to just say to the DMA, shift this 120bit chunk and let the mcu carry on doing other stuff?
2020-07-27T17:14:17 < karlp> what are you cooking for 2 hours at 3am anyway?
2020-07-27T17:14:22 < karlp> you s aid the blue was the induction cooker?
2020-07-27T17:14:39 < karlp> do you have electric home heating or something
2020-07-27T17:15:02 < zyp> ah, that, that's the outdoor jacuzzi
2020-07-27T17:15:25 < karlp> so the _orange_ is your cooktop then?
2020-07-27T17:15:32 < qyx> outdoor jacuzzi?
2020-07-27T17:15:33 < karlp> you said blue I think, I just saw when I was mentioned
2020-07-27T17:15:34 < qyx> in .no?
2020-07-27T17:15:36 < zyp> no, that's also blue
2020-07-27T17:15:44 < karlp> what's orange then?
2020-07-27T17:15:45 < zyp> these are phase metering
2020-07-27T17:15:57 < zyp> I've got 12 circuits, so four on each phase
2020-07-27T17:16:19 < zyp> the big main orange consumers seems to be floor heating
2020-07-27T17:16:34 < karlp> wouldn't have expected them to be cyclic as much,
2020-07-27T17:17:00 < karlp> not with such long gaps at least.
2020-07-27T17:17:06  * karlp shrugs.
2020-07-27T17:17:14 < karlp> not much in residential stuff that can really pull
2020-07-27T17:17:20 < zyp> why not? isn't that exactly what a thermostat with hysteresis would do?
2020-07-27T17:17:50 < karlp> well, it's a shitty design then :) if you want to avoid peak power charges, should cycle more for less.
2020-07-27T17:17:56 < karlp> should give you more even floor temps too
2020-07-27T17:18:20 < karlp> ~3 hours between heat bursts seems odd, but hey, I'm not electric floor heating expert
2020-07-27T17:18:30 < karlp> we just run a continuous hot water stream under them.
2020-07-27T17:18:31 < zyp> true, dunno if hysteresis can be configured
2020-07-27T17:18:54 < karlp> I would have though a ~continuous lower current should work just fine for radiant floor heating too.
2020-07-27T17:18:58 < zyp> this is tiled concrete, probably got a pretty big thermal mass
2020-07-27T17:20:26 < zyp> https://www.heatit.com/archived-products/heatit-z-trm2fx/ <- according to docs, hysteresis is configurable from 0.3-3.0C, default at 0.5C
2020-07-27T17:20:37 < zyp> i don't think I've changed it from the default
2020-07-27T17:20:38 < zyp> :)
2020-07-27T17:21:31 < karlp> seems reasonable temp step, still wouldnt' have expected such long cycles with 5A pulls though, 
2020-07-27T17:21:33  * karlp shrugs
2020-07-27T17:21:40 < karlp> anyway, problem fixed, back to holidays again :)
2020-07-27T17:21:52 < karlp> back in a week or so
2020-07-27T17:21:56 < zyp> I've also got multiple floors
2020-07-27T17:22:12 < zyp> and IIRC hot water is also yellow
2020-07-27T17:22:34 < karlp> a "nice" modern design would stagger the on times to keep peak loads down still.
2020-07-27T17:23:07 < zyp> true, I could probably do that once I've changed to smart thermostats everywhere
2020-07-27T17:23:23 < zyp> but at the moment I don't have peak power pricing
2020-07-27T17:23:34 < karlp> nah, haven't even heard of it for residential 
2020-07-27T17:23:53 < zyp> there's talk of introducing it, but last I checked they haven't decided how yet
2020-07-27T17:23:55 < karlp> just but with more people using home solar and shit, there's more demands for it.

2020-07-27T19:50:43 < fluiD> Ug, ok I've clearly screwed this up.
2020-07-27T19:52:46 < fluiD> I tried to modify my linker script to reserve some parts of flash. The script modifications partially worked because the code jumps where it's supposed to (looking at the hex dump) but I got to a HAL_Delay and my code crashes. There's a million "Cannot access memory at address" errors which tells me that I didn't set something up correctly.

2020-07-27T20:04:47 < fluiD> The STM32CubeIDE linker script defines RAM and FLASH. I split the FLASH into "VECTOR" "EEPROM1" "EEPROM2" "EEPROM3" "FLASH" and "EEPROM4"
2020-07-27T20:05:01 < fluiD> I put .isr_vector into VECTOR and everything else into FLASH
2020-07-27T20:05:24 < fluiD> except .bss and ._user_head_stack are still in RAM
2020-07-27T20:05:39 < fluiD> and .data is >RAM AT> FLASH
2020-07-27T20:19:44 < fluiD> according to a comment at https://electronics.stackexchange.com/questions/391645/stm32f4-adjust-linker-script-to-save-memory-for-eeprom-emulation the setup confuses the debugger.
2020-07-27T20:25:42 < fluiD> so maybe this is just a debugger problem
2020-07-27T20:25:59 < fluiD> so far the various examples I've found with google indicate I'm doing this correctly.
2020-07-27T20:27:28 < PaulFertser> idk, I'm using debugger with "eeprom emulation" just fine.
2020-07-27T20:27:33 < PaulFertser> I see no reason debugger can be confused about it.

2020-07-27T20:31:42 < fluiD> restored the original LD script and get the same error. OK, time to look elsewhere.
2020-07-27T20:34:35 < fluiD> I did a clean and recompile, but the debugger console still says "Address: 0x08010000" which is where the FLASH was in my custom linker script.
2020-07-27T20:39:01 < fluiD> oh, there we go. 0x08000000. Now the debugger doesn't complain about not accessing memory but comes down to void HardFault_Handler(void)
2020-07-27T20:41:06 < fluiD> ... which is because we get to the line that erases what used to be the emulated eeprom but which is now the main code :)

2020-07-27T21:37:36 < kakinull> Steffanx: nothing else
2020-07-27T21:37:38 < Steffanx> im pretty sure stm32 will say intel kakinull
2020-07-27T21:37:58 < Steffanx> 1x16GB? ARe you sure?
2020-07-27T21:38:09 < Steffanx> Also not in stock
2020-07-27T21:38:14 < kakinull> should I have 1x32GB?
2020-07-27T21:38:35 < fluiD> kakinull, you'll want memory in matching pairs
2020-07-27T21:38:50 < kakinull> aha
2020-07-27T21:39:26 < zyp> also lots of memory is good
2020-07-27T21:39:32 < kakinull> I cannot just buy same furyx later?
2020-07-27T21:39:34 < Steffanx> Why not 2x16 or 2x32 kakinull? :)
2020-07-27T21:39:39 < fluiD> "dual channel" memory meaning that the motherboard can communicate with two chips in parallel
2020-07-27T21:39:55 < kakinull> what is the performance impact?
2020-07-27T21:40:06 < fluiD> I use my laptop with a bunch of apps and typically don't have a problem with 16GB of ram on Windows 10.
2020-07-27T21:40:22 < Steffanx> https://imgur.com/a/NkGsf77 Yeah totally "useful" atm zyp ;)
2020-07-27T21:40:22 < kakinull> who does..
2020-07-27T21:40:26 < zyp> kakinull, well, theoretically two memory channels have twice the capacity of one
2020-07-27T21:41:00 < zyp> Steffanx, yeah?
2020-07-27T21:41:06 < Steffanx> No.
2020-07-27T21:41:16 < Steffanx> And i was even tempted to buy 64GB -_-
2020-07-27T21:41:29 < zyp> how so? unreserved memory is usually used for disk cache
2020-07-27T21:42:01 < fluiD> zyp, that *includes* the disk cache
2020-07-27T21:42:37 < fluiD> oh wait, I take that back.
2020-07-27T21:42:44 < zyp> bullshit, if you included cache it'd sit at 100% all the time
2020-07-27T21:43:05 < fluiD> I've looked before and noticed I don't use all of my ram for anything but checking just now I see that I have 8GB in use and 8GB in standby (not free)
2020-07-27T21:43:11 < fluiD> I stand corrected.
2020-07-27T21:43:48 < Steffanx> Where you see that in windows?
2020-07-27T21:43:57 < fluiD> resource manager
2020-07-27T21:44:01 < zyp> huh
2020-07-27T21:44:12 < Steffanx> ah yeah, i see
2020-07-27T21:44:14 < zyp> I'm actually using 5.68 GB of swap now
2020-07-27T21:45:27 < zyp> «PhysMem: 24G used (9353M wired), 46M unused.»
2020-07-27T21:45:44 < Steffanx> OS X fancy way of saying it.
2020-07-27T21:45:48 < Steffanx> *MAC OS
2020-07-27T21:46:05 < Steffanx> Still on some older hackintosh zyp?
2020-07-27T21:46:11 < zyp> yeah, 2012
2020-07-27T21:46:29 < zyp> bought 4x8GB at the time, pulled one some months ago because it died
2020-07-27T21:46:31 < fluiD> kakinull, be sure to check memory compatibility
2020-07-27T21:46:52 < zyp> since it's actually using 6GB of swap now, maybe it'd be worthwhile to replace it
2020-07-27T21:46:54 < Steffanx> Never bother to go for something more recent or .. dont want to?
2020-07-27T21:46:57 < Steffanx> *bothered
2020-07-27T21:47:05 < Steffanx>  / no need to
2020-07-27T21:47:22 < zyp> the latter, it still feels fast like a new computer
2020-07-27T21:47:47 < zyp> I don't really experience any performance bottlenecks anywhere
2020-07-27T21:48:01 < zyp> which I partly attribute to having lots of ram :p
2020-07-27T21:48:04 < Steffanx> Im tempted to try it again, but .. im actually fine with the windows nowadays.
2020-07-27T21:48:33 < zyp> eh, I think I'd rather give desktop linux a try than windows
2020-07-27T21:48:42 < Steffanx> not me.
2020-07-27T21:48:43 < Steffanx> lol
2020-07-27T21:48:51 < Steffanx> i'd still new the windows vms anyway
2020-07-27T21:51:07 < zyp> it's bad enough having to put up with windows at work when I'm getting paid for it
2020-07-27T21:51:14 < zyp> so I'd rather not :)
2020-07-27T21:51:17 < Steffanx> oh, no hackintosh i see. No support for my videocard.
2020-07-27T21:52:06 < zyp> yeah, apparently nvidia and apple had a fight
2020-07-27T21:52:36 < Steffanx> So which desktop lunix would it be for you?
2020-07-27T21:54:41 < zyp> dunno, maybe debian?
2020-07-27T21:56:04 < zyp> I'm running debian on other stuff because it actually works well, it's not full of fragile bullshit
2020-07-27T21:56:14 < zyp> but I haven't tried running it on a desktop yet
2020-07-27T21:56:16 < PaulFertser> I thought the question was about DE
2020-07-27T21:56:37 < zyp> oh
2020-07-27T21:56:44 < zyp> idk, I haven't been keeping up
2020-07-27T21:56:51 < PaulFertser> There you actually have a choice :)
2020-07-27T21:57:11 < PaulFertser> My brother uses KDE
2020-07-27T21:57:14 < upgrdman> color pros: if i want to convert from linear RGB to sRGB, is it just the gamma? e.g. sRGB red = linearRed^1/2.2     assuming gamma = 2.2?
2020-07-27T21:57:45 < upgrdman> i meant: linearRed^(1/2.2)
2020-07-27T21:57:57 < zyp> I've ran both kde and gnome back in the day, but that's so long ago I assume both changed a lot since
2020-07-27T21:58:27 < upgrdman> if i just do the ^(1/2.2) trick, light colors look good, but dark colors look too bright
2020-07-27T21:58:38 < zyp> I guess six years since last I touched gnome, and even longer since last I touched kde
2020-07-27T21:58:56 < Steffanx> No, it was about the combination PaulFertser . zyp himself called it "desktop linux".
2020-07-27T21:59:54 < zyp> PaulFertser, also, «actually have a choice»
2020-07-27T21:59:57 < qyx> what does 24G used, 9G wired mean?
2020-07-27T22:00:06 < qyx> 24G virtual, 9G of which is mapped?
2020-07-27T22:00:11 < zyp> are you saying it doesn't matter which distro you use?
2020-07-27T22:00:24 < zyp> qyx, no, virtual is a different number
2020-07-27T22:00:33 < zyp> VM: 4621G vsize, 1374M framework vsize, 10928437(0) swapins, 13197569(0) swapouts.
2020-07-27T22:01:22 < qyx> idk, we use to use words like "free", "used" and such
2020-07-27T22:02:44 < PaulFertser> zyp: I think it matters which distro one is using, and for most distros there's also a choice of DE. But people who migrate from windows usually look at DE first and if they do not feel comfortable they might just abandon the idea.
2020-07-27T22:03:04 < zyp> qyx, I think wired memory is physical memory that can't be swapped out
2020-07-27T22:03:14 < zyp> e.g. DMA buffers and the likes
2020-07-27T22:03:19 < Steffanx> KDE still kinda looks the same as it did ... 10 years ago. Maybe a tiny bit more "flat".
2020-07-27T22:03:34 < mawk> nonsense Steffanx 
2020-07-27T22:03:39 < mawk> KDE is polished and beautiful nowadays
2020-07-27T22:04:04 < kakinull> (x) doubt
2020-07-27T22:04:15 < zyp> PaulFertser, I don't care too much about the DE, my two main applications is chrome and terminal
2020-07-27T22:04:43 < Steffanx> I didnt say anything about ugly or someting related mawk
2020-07-27T22:04:51 < PaulFertser> zyp: but you're not a typical Windows user either :)
2020-07-27T22:05:21 < zyp> sure, but that's why I interpreted it as a distro question, not a DE question
2020-07-27T22:05:25 < mawk> you were thinking about it loudly Steffanx 
2020-07-27T22:05:27 < mawk> I know it
2020-07-27T22:07:11 < PaulFertser> zyp: you're probably right and I'm wrong, you know Steffanx better than me, agreed.

2020-07-27T22:07:43 < Steffanx> Yes he knows me better because i've met him a single time, and you 0 times ;)

This works and I am able to power the radio on, set volume and set a station in setup(). However, subsequent calls to set channel in loop() are fragile, in that they sometimes cause the device to always emit the same static, no matter the channel. Same fo

2020-07-28T00:18:01 < soreau> after this happens, the only way to fix it is to reset the device. I tried powering off and on the radio, controlling it by a pin, but I couldn't get it back to a usable state, after calling the initialization routines (which apparently can't be called from loop(), only setup())
2020-07-28T00:19:48 < karlp> qyx: there's a datacenter company that makes locky type 13/14 connectors, if you want... won't be china cheap of course...
2020-07-28T00:20:50 < soreau> if I am using the stm32f1 as a usb device, can I use PB6/7 for SCLK/SDIO safely? or what pins would the radio ideally be connected to?

2020-07-28T01:02:06 < jadew> I upgraded my projects to C++ to gain access to a feature and it broke all my SFINAE crap
2020-07-28T01:02:32 < jadew> had to switch to concepts - much nicer
2020-07-28T01:03:13 < jadew> it's practically the same shit, with syntactic sugar
2020-07-28T01:03:59 < zyp> to C++20, you mean?
2020-07-28T01:04:06 < jadew> yeah, missed the 20 :P
2020-07-28T01:04:12 < fluiD> What can I do if my code seems to bypass IF statements when optimized with -O2 but not when optimized with -Og?
2020-07-28T01:04:31 < jadew> fluiD, check the asm output?
2020-07-28T01:04:33 < zyp> fix your code, stop relying on incorrect assumptions
2020-07-28T01:05:24 < zyp> when the compiler optimizes out something it shouldn't, it's because you've led it to believe it's unnecessary
2020-07-28T01:05:35 < fluiD> hmm...
2020-07-28T01:05:46 < zyp> pastebin the code?
2020-07-28T01:06:24 < PaulFertser> fluiD: probably you're just getting confused by compiler reordering code and it checks that IF later.
2020-07-28T01:06:49 < PaulFertser> fluiD: debugging optimised code takes some getting used to, you'll see source code jumping back and forth and it's normal.
2020-07-28T01:06:55 < zyp> that might also be, if we're talking about stepping in the debugger

2020-07-28T01:07:01 < fluiD> three IF statements in a row. If I start my program and breakpoint on any of the three IF statements, they all are reached and they all do what they say.
2020-07-28T01:07:36 < fluiD> If I create an external trigger that calls some other routine, suddenly the middle IF statement is skipped and continues to be skipped until I reboot
2020-07-28T01:07:48 < zyp> how do you tell it's skipped?
2020-07-28T01:07:52 < fluiD> yeah, I see the jumping back and forth and I'm fine with that
2020-07-28T01:08:23 < fluiD> the breakpoint is skipped, and the code in question is what sends output to the serial port, so I see all the output stop. The rest of the code keeps running because my buffer fills up.
2020-07-28T01:08:26 < jadew> fluiD, when in doubt, add console output code
2020-07-28T01:08:40 < jadew> cout << "whatever just happened" << endl;
2020-07-28T01:08:44 < fluiD> I have lots of console output, which is how I know what's going on.
2020-07-28T01:09:01 < zyp> fluiD, did you forget to declare something volatile? :)
2020-07-28T01:09:12 < jadew> well, you should be able to debug then and figure out where it stops doing what it should
2020-07-28T01:10:05 < fluiD> Here's the code in question: https://snipboard.io/eYIRNb.jpg
2020-07-28T01:10:54 < fluiD> The ToGalilQueue is added to at 10Hz, so the If at line 356 checks the count and sends the data.
2020-07-28T01:10:56 < zyp> that's not enough to make much sense of
2020-07-28T01:11:21 < fluiD> but a separate external event can also add to the ToGalilQueue, and doing that is when this IF statement is skipped.
2020-07-28T01:11:50 < fluiD> ToGalilQueue is not volatile, it's a variable in main()
2020-07-28T01:12:18 < zyp> and it's added to by an interrupt handler?
2020-07-28T01:12:47 < fluiD> the only thing touched by the interrupt handler is the huart stuff
2020-07-28T01:13:59 < zyp> you have to show more code if you want anybody to get something useful out of it
2020-07-28T01:14:08 < fluiD> ok
2020-07-28T01:16:58 < zyp> so far this looks like a classic missing volatile situation; you have some code waiting for something, compiler doesn't see the value of something changing so it assumes the check will always return false and optimizes it out
2020-07-28T01:17:04 < zyp> potentially
2020-07-28T01:17:30 < fluiD> <nod>
2020-07-28T01:17:50 < fluiD> Is it idiotic to just VOLTAILE a bunch of things until it's happy.
2020-07-28T01:17:52 < fluiD> ?
2020-07-28T01:17:55 < zyp> yes
2020-07-28T01:17:56 < karlp> nice one jade, recommneding printf debugging :)
2020-07-28T01:19:19 < zyp> fluiD, I mean, as a quick test you could throw volatile at both the queue and the huart instance
2020-07-28T01:19:58 < zyp> that's not necessarily the correct end solution, but if that makes it work you know you're on the right track
2020-07-28T01:20:10 < fluiD> roger. I'll give that a try. Thanks.
2020-07-28T01:20:15 < jadew> karlp, it's very reliable :)
2020-07-28T01:20:55 < fluiD> this is true
2020-07-28T01:21:15 < fluiD> optimization -O1 does it, too
2020-07-28T01:23:08 < zyp> it's generally not very interesting which optimization levels it breaks at and which it works at, unless you're debugging an issue in one of the optimizations itself
2020-07-28T01:23:35 < zyp> normally if the code breaks at any optimization levels, it's broken and should be fixed
2020-07-28T01:23:52 < fluiD> ok, good to know. thanks
2020-07-28T01:25:08 < zyp> and those kinds of failures are usually either because your code makes an incorrect assumption about something, or you're letting the compiler make an incorrect assumption about your code
2020-07-28T01:25:10 < fluiD> I labeled the queue as volatile and I ended up in HardFault_Handler.
2020-07-28T01:25:24 < fluiD> ok, so now I have something to chase
2020-07-28T01:25:30 < zyp> ouch :)
2020-07-28T01:25:45 < zyp> are you sure you didn't hardfault before?
2020-07-28T01:25:56 < zyp> that'd explain why everyting stopped outputting
2020-07-28T01:26:22 < fluiD> Before I could pause and resume execution of the code, and verify which breakpoints were being skipped.
2020-07-28T01:27:15 < zyp> fair
2020-07-28T01:27:19 < fluiD> I trigger the hard fault at the same time I previously started skipping the breakpoint
2020-07-28T01:27:44 < zyp> that's interesting
2020-07-28T01:28:02 < karlp> trampling memory now that it's being treated properly
2020-07-28T01:28:11 < zyp> adding volatile to something usually doesn't make it hardfault :)
2020-07-28T01:28:18 < karlp> previously it was ignored,
2020-07-28T01:28:31 < karlp> now it's executed, but is bad code, and you trash pointers
2020-07-28T01:28:40 < zyp> yeah, I guess it must be something like that

2020-07-28T11:28:18 < dongs> is that too much to ask?
2020-07-28T11:28:23 < zyp> haha
2020-07-28T11:29:19 < c10ud> I think w_scan is all I ever saw
2020-07-28T11:30:57 < dongs> and apparently ALL of these have LNB freqs hardcoded
2020-07-28T11:31:04 < dongs> because who teh fuck would ever have a non-standard LNB frequency RIGHT
2020-07-28T11:31:36 < dongs> now im trying to recompile dvbv5-tools or wahtever the FUCK because of one change and it depends on udev and apparently some header/dev file wasnt installed, i installed that and it UPDATED THE KERNEL
2020-07-28T11:31:40 < dongs> like what the FUCK GUYS?
2020-07-28T11:31:53 < dongs> so apaprently udev wasn't in byt default or something and when I rebvoot this trash its prolly going to shit itself
2020-07-28T11:32:05 < dongs> absolute clusterfuck of nonworking shit = lunix
2020-07-28T11:32:41 < c10ud> I miss my linux days, hope to get back there eventually
2020-07-28T11:33:15 < c10ud> btw -dev packages pulling in kernel updates
2020-07-28T11:33:18 < c10ud> weird
2020-07-28T11:34:12 < dongs> damn, the LNB list is in /lib/x86_64-linux-gnu/libdvbv5.so.0
2020-07-28T11:34:28 < dongs> and i bet that shit was custom built cuz its in /lib and not in /usr/lib so - need to fuck around with some bullshit prefix adding to configure etc
2020-07-28T11:34:28 < PaulFertser> When you're compiling from sources dev files are needed, so yes, probably udev dev files weren't installed but you usually do not need all dev files from all the packages on a regular system.
2020-07-28T11:37:19 < c10ud> dongs, usually apt-source and apt build dep or some shit helps
2020-07-28T11:39:11 < dongs> i spent ~2 hours on this, still not able to tune a single frequency
2020-07-28T11:39:21 < dongs> in windows i was done in 5 mins
2020-07-28T11:39:54 < dongs> > Most common applications used for channel scan:

2020-07-28T11:40:37 < c10ud> i see it's a two-liner with w_scan and vlc
2020-07-28T11:40:39 < dongs> this comes up from 13 years ago
2020-07-28T11:40:52 < dongs> the actual fuckign format of the god damn file it wants is NOT DOCUNMENTED ANYWHERE
2020-07-28T11:41:18 < c10ud> https://linuxtv.org/wiki/index.php/VLC_media_player
2020-07-28T11:41:24 < dongs> what
2020-07-28T11:42:06 < dongs> this is headless shit on esxi
2020-07-28T11:42:11 < dongs> why the fuck would I have gui on lunix
2020-07-28T11:42:29 < c10ud> replace vlc with cvlc and you're done I suppose?
2020-07-28T11:42:36 < dongs> to do what?
2020-07-28T11:42:48 < dongs> how does that change the fact that libdvbnigger5 has a hardcoded lnb list and mine isn't on there?
2020-07-28T11:43:03 < c10ud> idk what you're doing ?
2020-07-28T11:43:22 < dongs> it started with me treying to tune a known frequency on dvb-s2
2020-07-28T11:43:25 < dongs> with all parameters known
2020-07-28T11:43:29 < dongs> but apparently i need to 'scan" first
2020-07-28T11:43:35 < dongs> and none of the 'scan' shit works.
2020-07-28T11:43:37 < dongs> so now im here.
2020-07-28T11:43:52 < zyp> why do you need to scan when you know the freq?
2020-07-28T11:43:56 < qyx> w_scan and vlc works
2020-07-28T11:43:58 < dongs> zyp, FUCKING EXACTLY
2020-07-28T11:44:08 < qyx> so specify manually
2020-07-28T11:44:09 < dongs> zyp, because the fucking TUNE program needs a "channels.conf"
2020-07-28T11:44:15 < dongs> which is generated by "scan"
2020-07-28T11:44:19 < c10ud> "vlc -vvv dvb-s2:// :dvb-frequency=10714300 :dvb-srate=22000000 :dvb-polarisation=H :dvb-adapter=0 :dvb-device=1 :dvb-fec=5 "
2020-07-28T11:44:24 < c10ud> replace vlc with cvlc and pray
2020-07-28T11:44:26 < dongs> fuck knows what format because its trash and undocumented
2020-07-28T11:45:16 < c10ud> seems pretty straightforward to me...now, working is another story..
2020-07-28T11:45:44 < qyx> I am using the same approach
2020-07-28T11:45:48 < dongs> > Note: szap-s2 requires Linux DVB driver API version 5 -- i.e. use kernel 2.6.28 or later.

2020-07-28T11:48:05 < qyx> channels.conf format is the name of the format itself

2020-07-28T11:48:26 < dongs> yea thats old and for vdr
2020-07-28T11:48:34 < qyx> idk, w_scan generates one
2020-07-28T11:48:40 < qyx> it also generates a couple of other formats
2020-07-28T11:48:45 < zyp> haha
2020-07-28T11:48:49 < zyp> now we're full circle
2020-07-28T11:49:06 < qyx> and you can specify freq and shit in w_scan
2020-07-28T11:49:24 < qyx> or tell it to use saved tables for your country
2020-07-28T11:49:51 < c10ud> i think wanting to use that szap tool may be part of the issue.. why use unmantained stuff instead of proven tools?
2020-07-28T11:50:06 < zyp> sounds like a lot of bullshit, I figure proper solution would be using something proper to tune the shit
2020-07-28T11:52:13 < Steffanx> Why is mr d even using lunix?!
2020-07-28T11:52:19 < Steffanx> Where did it go wrong
2020-07-28T11:55:27 < c10ud> btw it looks like all those tools you mentioned are somehow superseded https://linuxtv.org/wiki/index.php/DVBv5_Tools
2020-07-28T12:08:41 < dongs> of course.
2020-07-28T12:09:03 < dongs> we're back to the thing wehre libdvbnigger5 has a hardcoded lnb list.
2020-07-28T12:09:08 < dongs> mine's LO is at 11200.
2020-07-28T12:09:31 < dongs> i didn't even start looking into whether i can generate a tone with these tuning apps or not
2020-07-28T12:09:52 < dongs> cuz thats next hurdle
2020-07-28T12:13:34 < c10ud> just do an universal scan
2020-07-28T12:14:00 < c10ud> or simply create a channel file with dvbv5 syntax
2020-07-28T12:14:14 < c10ud> which is in the very same page of dvbv5-scan
2020-07-28T12:20:07 < c10ud> now, if you want to talk about how STM, Xilinx et al. called their openamp includes for errno.h, well, errno.h and that breaks their own build...well that I could back it
2020-07-28T12:21:22 < dongs> i dont know what "openamp" is but it has 'amp' in the name so it can burn in hell

2020-07-28T17:34:03 < zyp> some of those operations are unnecessary, but it's more readable to keep it consistent
2020-07-28T17:34:04 < t4nk_freenode> kewl, zyp
2020-07-28T17:37:16 < zyp> e.g. the &0xf is kinda redundant, because the shifts are already kinda masking it
2020-07-28T17:37:35 < zyp> or you could combine both shifts and mask with 0xf0 instead
2020-07-28T17:38:10 < zyp> but it doesn't matter, compiler should optimize it either way

2020-07-28T19:40:05 < bitmask> I dont know why but I ordered 2
2020-07-28T19:41:39 < Steffanx> Did you get another Trump $1k?
2020-07-28T19:42:01 < zyp> t4nk_freenode, doesn't look hard to do
2020-07-28T19:42:35 < t4nk_freenode> no, it would be a nice little project, also to test my hot air gun
2020-07-28T19:42:42 < bitmask> no not yet
2020-07-28T19:43:00 < zyp> meh, I'd just do it with an iron
2020-07-28T19:43:01 < bitmask> also dont make fun of me but I bought a hantek handheld 3 in 1
2020-07-28T19:43:08 < bitmask> just a temporary scope
2020-07-28T19:43:12 < zyp> makes it easier to not touch any other parts
2020-07-28T19:43:30 < bitmask> just wanna learn on it
2020-07-28T19:43:41 < bitmask> so if I blow it up its ok
2020-07-28T19:44:25 < zyp> bitmask, only two?
2020-07-28T19:44:39 < bitmask> why would I need more?
2020-07-28T19:45:04 < Steffanx> why would you need 2?

2020-07-28T19:48:04 < t4nk_freenode> just don't buy cheap grabbers, those grab just fine... for about  a day
2020-07-28T19:48:31 < jpa-> https://sigrok.org/wiki/Probe_comparison  is useful
2020-07-28T19:49:31 < bitmask> i got the pomona
2020-07-28T19:49:42 < t4nk_freenode> The Pomona Grabber probes seem of similarly good quality (and also have only one pin where you can attach). 
2020-07-28T19:49:57 < t4nk_freenode> ... this is important to have only one pin
2020-07-28T19:50:17 < bitmask> maybe I didnt choose so bad after all

2020-07-28T19:52:33 < t4nk_freenode> well, I can only testify for the 'cheap probe 2' on that page,
2020-07-28T19:53:33 < t4nk_freenode> but I think you will always put stress on the grabbers, and it's really tiny and feable stuff as it is
2020-07-28T19:53:56 < t4nk_freenode> so if those tips don't line up.. you're done for 
2020-07-28T19:54:03 < bitmask> oh I didnt get a grabber, its the pomona 72902
2020-07-28T19:54:15 < t4nk_freenode> I know
2020-07-28T19:58:00 < emeb> I've got a Saleae with the associated grabbers. They're great but sometimes I'd like to use them with other things and the pins are too small to connect to std DuPonts.

2020-07-28T20:20:04 < emeb> Years ago I got some sets of "cheap probe 1" which are ok for a while but eventually fail. The wires are merely stripped and soldered with no strain relief, so after some flexing they always break off.
2020-07-28T20:25:17 < t4nk_freenode> heh, I resoldered all of mine, and also rerouted the leads; originally you would squeeze the cable/joint each time you use them
2020-07-28T20:25:38 < t4nk_freenode> now I made a little loop in the cable and led them away to the other side
2020-07-28T20:25:50 < t4nk_freenode> however... then the grapplers started to fail
2020-07-28T20:26:28 < t4nk_freenode> AND... the tube is made of dodgy plastic, so they are worn away in no time
2020-07-28T20:27:23 < t4nk_freenode> so even if the metal parts are ok.. the tube that guides them is worn away, and the grapplers can never work 
2020-07-28T20:31:41 < t4nk_freenode> would be nice to see if I could replace the tips of the ones I broke... with a metal tube

2020-07-29T12:28:14 < PaulFertser> I used cyrillic letters in my name when ordering from Adagio teas for whatever reason. And utf-8 was treated as ISO_8859-1 and the post office had doubts whether they should give me the package because the result ( Ðавел ) looked nothing like my real name.
2020-07-29T12:28:59 < zyp> Steffanx, no øs here
2020-07-29T12:29:07 < zyp> but I live in Kjæråsen
2020-07-29T12:30:23 < zyp> so I told them to just substitute Kjaeraasen
2020-07-29T12:38:15 < jpa-> why not "Lovely hill"

2020-07-29T12:43:04 < t4nk_freenode> zyp is a viking name??
2020-07-29T12:43:24 < t4nk_freenode> had he been called 'Wicky',.. then I mightta suspected something

2020-07-29T13:59:10 < benishor> is it worth though?
2020-07-29T13:59:20 < jadew> I'm wondering the same

2020-07-29T14:01:14 < jadew> that's pretty much all I do
2020-07-29T14:02:01 < jadew> on my current tweezers the tips got bent, and they can't grip fine things anymore (like very thin wire)
2020-07-29T14:02:31 < PaulFertser> I wonder if you can get medical tweezers from your friends.
2020-07-29T14:02:45 < PaulFertser> They seem to be made from nice metal
2020-07-29T14:02:52 < jadew> I could, but I don't think they're sharp enough

2020-07-29T18:55:17 < Mangy_Dog> ive had occations before with errored packets or some desync soooooo trying to make a system that picks up on that and corrects or resends

2020-07-29T18:56:09 < Mangy_Dog> and i couldnt even create error correction for it
2020-07-29T18:56:25 < srk> run RS-485 instead :)
2020-07-29T18:56:30 < srk> if it's long wire
2020-07-29T18:56:40 < Mangy_Dog> its a few inches nothing more
2020-07-29T18:56:45 < srk> is that for reflow oven?
2020-07-29T18:57:02 < Mangy_Dog> na thats finished
2020-07-29T18:57:34 < srk> in that case it shouldn't have problems with noise unless there are motors or so around :)
2020-07-29T18:58:35 < srk> for serial overflows are sometimes the problem, you can run with flow control with rts/cts pins connected as well
2020-07-29T18:59:19 < srk> like i2c/spi/can are way easier to handle compared to serial..

2020-07-29T23:40:44 < fluiD> the worst part of programming in Delphi is seeing all the sins of the 90s when you google for help. Bad colors, dancing babies, weird font sizes.
2020-07-29T23:41:04 < zyp> delphi still exists?
2020-07-29T23:41:13 < fluiD> barely
2020-07-29T23:41:32 < zyp> I thought the worst part of programming in delphi was the pascal
2020-07-29T23:42:16 < fluiD> I'm stuck supporting some legacy application that was originally written in a different variant of pascal called XPL0. We finally upgraded from Delphi 6 to Tokyo (about 15 years difference) and it's pretty clear the company running doesn't care at all.
2020-07-29T23:42:20 < strata> what i wanna know is how can a website written in asp be so bad it throws error 500's and/or incomplete documents followed by waiting for the web server to come back up if i accidentally put a date with the incorrect format in a search form 
2020-07-29T23:42:41 < strata> and this is a site i need to scrape
2020-07-29T23:42:53 < strata> now i gotta worry about getting arrested for DDoS or some bullshit
2020-07-29T23:43:08 < zyp> fluiD, the obvious question is «is it even worth it?»
2020-07-29T23:43:57 < fluiD> I tried to get permission to rewrite it in a sane language. The boss's argument was, "Pascal was the official language chosen by University of Pittsburgh in 1974" or something like that.
2020-07-29T23:44:19 < fluiD> He also thinks Coronavirus is, "a ploy to make Trump look bad," so I don't expect him to live much longer.
2020-07-29T23:44:29 < zyp> haha

2020-07-29T23:57:24 < ds2> pascal is good. there are no pointers so one can't corrupt the stack and do other bad things
2020-07-29T23:57:33 < ds2> keeps wear and tear down on the fault handlers :D
2020-07-29T23:58:08 < fluiD> there are pointers in Delphi
2020-07-29T23:58:41 < fluiD> but you can do nice things like var i: integer; var f: float absolute i;
2020-07-29T23:58:53 < ds2> Delphi is not pascal
2020-07-29T23:58:59 < ds2> neither is turbopascal ;)
2020-07-29T23:59:21 < ds2> got to keep programmers in nice padded rooms before they do damage
2020-07-29T23:59:44 < fluiD> yes, and c89 is not c
2020-07-29T23:59:53 < fluiD> but these are semantics

2020-07-30T00:39:07 < qyx> whats wrong
2020-07-30T00:39:19 < zyp> workstuff got one of those three port ethernet switch chips, it got a low latency mode that makes it act like a repeater (hub)
2020-07-30T00:39:51 < zyp> when we got the hardware like three years ago I had some problems getting ethernet to work, found out it was related to the repeater mode, turning it off made it work
2020-07-30T00:40:21 < zyp> and then we haven't bothered putting time into working that out before now
2020-07-30T00:41:11 < zyp> it still fucks up
2020-07-30T00:43:01 < zyp> switch chip claims there's collisions, but I don't get what is colliding
2020-07-30T00:46:37 < zyp> I have a pretty simple test case now, got a master board (with switch chip) hooked up to an off the shelf slave, profishark to tap the traffic between the two
2020-07-30T00:47:51 < zyp> master sends an IDENT_REQUEST, slave replies with IDENT_RESPONSE, master never receives the response, switch counts a collision
2020-07-30T00:48:14 < qyx> hm
2020-07-30T00:48:15 < zyp> master shouldn't be sending anything else, so I don't get what's going on
2020-07-30T00:50:20 < zyp> yesterday I also tried with the profishark on the other port of the switch
2020-07-30T00:51:00 < zyp> and then it looked like the slave responses were making it between the two external ports on the switch, not just the RMII port to the MCU
2020-07-30T00:51:02 < qyx> have you tried without it?
2020-07-30T00:51:10 < zyp> without what?
2020-07-30T00:51:16 < qyx> withut the profishark
2020-07-30T00:51:21 < zyp> obviously
2020-07-30T00:51:35 < zyp> also shouldn't matter it's almost transparent
2020-07-30T00:52:15 < zyp> pretty sure the copper side is fine, issue seems to be around the RMII interface
2020-07-30T00:52:36 < zyp> I wonder if I'm gonna end up having to probe it to figure it out

2020-07-30T01:24:24 < zyp> sounds unrealistic, but hey
2020-07-30T01:25:15 < qyx> did you try other slave?
2020-07-30T01:25:17 < zyp> a minimum ethernet frame is 8 octets of preamble, 64 octets of data and 12 octets of IPG, that's 672 bit-times, i.e. 6.72 microseconds
2020-07-30T01:27:02 < zyp> profishark reports that the time delta between request and reply is about 9.7 microseconds, so that should be good
2020-07-30T01:27:12 < zyp> (and yes, the request is a minimum frame)
2020-07-30T01:27:41 < qyx> isnt there an interframe delay required?

2020-07-30T01:38:34 < ds2> it needs a time offset to find the right edge

2020-07-30T01:39:17 < ds2> that should be a well behaved phy

2020-07-30T01:39:40 < zyp> well, it works perfectly when operated as a switch
2020-07-30T01:39:55 < zyp> it just fucks up in repeater mode

2020-07-30T01:40:18 < zyp> in what sense?
2020-07-30T01:40:26 < ds2> does it work on a dumb hub?
2020-07-30T01:40:37 < ds2> switches have many tricks depending on the mfg
2020-07-30T01:40:49 < zyp> repeater mode turns it into a dumb hub
2020-07-30T01:41:00 < ds2> I mean the peer is a dumb hub
2020-07-30T01:41:17 < zyp> there's no other switches involved
2020-07-30T01:41:28 < ds2> oh
2020-07-30T01:41:58 < zyp> this is industrial shit, dedicated network with timeslots
2020-07-30T01:42:18 < zyp> which is why it can operate with hubs, there's a master controlling access by polling everything
2020-07-30T01:42:31 < ds2> oh not pure ethernet?
2020-07-30T01:42:31 < zyp> so there shouldn't ever be any bus contention
2020-07-30T01:42:53 < zyp> L2 is pure ethernet
2020-07-30T01:43:30 < zyp> L3 is POWERLINK
2020-07-30T01:43:43 < zyp> which is essentially a cheaper alternative to ethercat
2020-07-30T01:45:37 < zyp> both ethercat and powerlink are essentially canopen over ethernet, ethercat is based on slaves having special MACs that can rewrite a frame as it is passing through, powerlink is based on a poll/response pattern that can be implemented with standard MACs
2020-07-30T01:47:33 < zyp> not that I care much about the canopen stuff
2020-07-30T01:47:59 < zyp> apart from an off the shelf gateway, I don't have any third party devices on the network, so I've only implemented the useful subset of it
2020-07-30T01:49:57 < zyp> anyway, I need to wake up in six hours and I'm not getting further with this now either way so… :)
2020-07-30T01:51:39 < zyp> I'll probably have to look at the RMII to make any sense of anything, so I guess I could ghetto up something with some of the FPGA stuff floating around on my desk

2020-07-30T21:41:10 < mawk> they sent me a letter
2020-07-30T21:41:12 < mawk> they're called Regionale Belasting Groep

2020-07-30T21:43:09 < kakinull> kaki is active
2020-07-30T21:47:28 < Steffanx> They want your munny mawk?
2020-07-30T21:47:41 < Steffanx> Google the name and check the review/score :D
2020-07-30T21:57:39 < bitmask> hmm, this cherry red carbon fiber seems to string more than the black
2020-07-30T21:58:19 < Steffanx> dont do that
2020-07-30T22:11:05 < mawk> yes Steffanx 
2020-07-30T22:11:09 < mawk> 400€
2020-07-30T22:11:18 < kakinull> movie required
2020-07-30T22:11:28 < mawk> because I'm not homeless
2020-07-30T22:11:32 < mawk> it's the not homeless tax
2020-07-30T22:11:53 < mawk> I already pay 1050€ for 45m² that are actually 35m², and now they want money on top of that
2020-07-30T22:12:14 < bitmask> just say no
2020-07-30T22:12:25 < bitmask> yes to drugs, no to taxes
2020-07-30T22:13:16 < bitmask> I spent $30 on sushi and then realized I couldn't eat it...
2020-07-30T22:13:43 < bitmask> what a waste
2020-07-30T22:14:25 < Steffanx> That's yearly i assume mawk?
2020-07-30T22:14:45 < Steffanx> For them to take your trash, dog keeping money etc.
2020-07-30T22:15:03 < bitmask> sewage
2020-07-30T22:15:06 < Steffanx> yeah
2020-07-30T22:15:25 < mawk> yes per person
2020-07-30T22:15:28 < bitmask> you would think your poop would be enough payment
2020-07-30T22:15:38 < mawk> well this is a living tax Steffanx it's not for poop or what
2020-07-30T22:15:46 < mawk> it's computed on the surface of the apartment
2020-07-30T22:16:21 < Steffanx> Whats the name of this tax on the bill mawk?
2020-07-30T22:16:29 < bitmask> thats for an apartment? those taxes are usually factored into the apartment rent here and then the property owner pays the taxes
2020-07-30T22:16:52 < Steffanx> This is dutchland, not yankeeland
2020-07-30T22:17:02 < bitmask> yes i know, thats why i explained the situation here :)
2020-07-30T22:17:05 < Steffanx> but yeah, its similar here i guess
2020-07-30T22:17:21 < mawk> I guess 225€ of the 400€ is for trash picking

2020-07-30T23:55:16 < Steffanx> Ah
2020-07-30T23:56:47 < PaulFertser> I didn't fully shred though, just cut with a knife to reasonably small pieces.

2020-07-31T00:16:36 < BrainDamage> the cinnamon will only add a hint of sweetness

2020-07-31T02:51:56 < fluiD> Once I start talking to the STM32 through my debugger that I/O pin stops being high.
2020-07-31T02:52:08 < fluiD> is that maybe a pull-up on MISO?

2020-07-31T09:30:42 < dongs> does this work?
2020-07-31T09:34:40 < jpa-> in some ways yeah
2020-07-31T09:35:09 < jpa-> but automatically picking random *.c files into your build gets annoying after a while
2020-07-31T09:38:00 < dongs> so hwo the FUCK do i build something with million C files like typical opensores
2020-07-31T09:38:05 < dongs> oh fuck ant wildcard isnt even recursive
2020-07-31T09:38:05 < dongs> wtf
2020-07-31T09:38:25 < dongs> also this shit is ignoring Cflags

2020-07-31T09:39:09 < dongs> why wouldnt this work?
2020-07-31T09:48:50 < PaulFertser> dongs: it's a template, it says whenever an .o file is needed for some target, make it from .c file like this
2020-07-31T09:49:10 < PaulFertser> dongs: so it does work but it doesn't specify any specific way to find files or anything like that.

2020-07-31T10:02:17 < PaulFertser> dongs: yes, the easiest way would be to use $(shell find ...)
2020-07-31T10:02:32 < PaulFertser> If you can count on find being available (as it is on any POSIX system I guess).
2020-07-31T10:02:48 < PaulFertser> find -iname \*.c -print
2020-07-31T10:02:59 < dongs> christ.
2020-07-31T10:03:05 < PaulFertser> Oh, for full compatibility it would be "find . -iname *.c -print"
2020-07-31T10:03:23 < PaulFertser> * should be escaped appropriately
2020-07-31T10:03:37 < dongs> how can Make not have something as basic as OBJS = (get *.c in a folder(s))
2020-07-31T10:03:40 < PaulFertser> Guess it needs \ or even \\ in the makefile
2020-07-31T10:04:17 < PaulFertser> find command is the tool for the job, why not use it? make was written with assumption that basic utilities are available.
2020-07-31T10:04:42 < dongs> how would i get current_time() on lunix as seconds in UTC
2020-07-31T10:04:49 < dongs> is that time() for thaT?
2020-07-31T10:04:53 < dongs> or does that return in timezone
2020-07-31T10:06:44 < zyp> dunno about seconds in UTC, but there's gmtime() to get a struct tm*

2020-07-31T10:08:18 < dongs> oh is it?
2020-07-31T10:08:23 < PaulFertser>        time() returns the time as the number of seconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).
2020-07-31T10:08:28 < dongs> nICE
2020-07-31T10:08:50 < PaulFertser> time_t is the return type. So if you libc switched to 64bit time_t then it is 64 bits.

2020-07-31T12:59:55 < PaulFertser> I'm using it too but that's because 1. I had to learn it anyway for many different projects; 2. I do not like the tools commonly considered to be better alternatives and I do not want to use something experimental either.

2020-07-31T19:00:02 < jadew> linux is so fucking stupid
2020-07-31T19:00:39 < t4nk_freenode> nah, you're just so $@#$@$ bright!
2020-07-31T19:00:59 < jadew> the people behind it must be fucking retards...
2020-07-31T19:01:32 < jadew> on the new systemd they removed rc.local, I assume in the idea of forcing people to make proper startup services
2020-07-31T19:01:46 < PaulFertser> systemd is not part of Linux, luckily
2020-07-31T19:01:50 < t4nk_freenode> heh
2020-07-31T19:01:51 < jadew> but jesus... that system is stupid beyond belief
2020-07-31T19:01:55 < t4nk_freenode> and we don't use it either ;)
2020-07-31T19:02:16 < jadew> it won't expose the fucking path to you
2020-07-31T19:02:18 < PaulFertser> That said, few times I wrote systemd units it felt OKish.
2020-07-31T19:02:30 < jadew> the whole internet is full of hackish solutions on how to do that
2020-07-31T19:02:41 < jadew> they even have a parameter for that shit, but it doesn't work properly
2020-07-31T19:02:59 < jadew> I mean... WTF kind of moron puts that kind of garbage out?
2020-07-31T19:03:15 < jadew> fucking shit... this is so infurating
2020-07-31T19:03:28 < jadew> iptables not found
2020-07-31T19:03:46 < jadew> you fucking piece of shit!
2020-07-31T19:04:25 < jadew> there is an Environment thing you can use to expose environment variables to the script, but it won't expand $PATH
2020-07-31T19:04:40  * t4nk_freenode takes a look at the swear jar and orders some steaks
2020-07-31T19:04:44 < jadew> you have to hardcode system dependent paths in there
2020-07-31T19:04:48 < jadew> that's how retarded they are
2020-07-31T19:05:23 < jadew> the solution is that instead of putting the path to your script in the ExecStart parameter, you put bash
2020-07-31T19:05:39 < jadew> and make it run multiple commands, one of which is PATH=$PATH!!!
2020-07-31T19:05:46 < jadew> and the other one is your script
2020-07-31T19:05:56 < jadew> ready for the desktop my ass
2020-07-31T19:07:59 < jadew> that's what I get for trying to organize my shit in on linux, you can't organize your stuff in a fucking dump
2020-07-31T19:10:35 < jadew> all I wanted was to run a script at startup...
2020-07-31T19:11:20 < zyp> just make a unit?
2020-07-31T19:11:41 < jadew> I tried that, but iptables not found, because the PATH environment variable is not exposed
2020-07-31T19:11:49 < jadew> and that's what I'm ranting about
2020-07-31T19:12:13 < jadew> you either have to hardcode the system paths in the Environment parameter or you have to use the stupid bash hack, which sets the PATH and then runs your thing
2020-07-31T19:12:46 < zyp> so? just write /sbin/iptables
2020-07-31T19:13:06 < jadew> but I don't want to do that, because I'm not writing the config directly in /etc/
2020-07-31T19:13:16 < jadew> I'm making a config file for the service and linking it there
2020-07-31T19:13:32 < jadew> in the idea that next time I install the system I can just drop it in a folder and say ./install
2020-07-31T19:14:14 < jadew> but if I'm forced to hardcode stuff that shouldn't be hardcoded, it might break on the next install
2020-07-31T19:15:01 < zyp> path search is a shell thing, so it's pretty natural that either you use a shell or you use an absolute path
2020-07-31T19:15:06 < jadew> what are my options if I want to go down that route? make the installer figure out the paths and then replace them?
2020-07-31T19:15:40 < jadew> I am using sh, but it comes out with no environment variables
2020-07-31T19:15:44 < mawk> expose which path jadew 
2020-07-31T19:15:49 < jadew> mawk, PATH
2020-07-31T19:15:51 < mawk> you mean in a service file ?
2020-07-31T19:15:54 < jadew> yeah
2020-07-31T19:16:00 < jadew> in the script
2020-07-31T19:16:01 < mawk> just prefix with - or + I forgot which one
2020-07-31T19:16:05 < mawk> it allows to use PATH
2020-07-31T19:16:19 < mawk> but it's better to use absolute path in such situations, PATH is pretty brittle
2020-07-31T19:16:45 < mawk> and iptables is always in /sbin as far as I know of
2020-07-31T19:17:23 < zyp> jadew, IIRC default env vars and shit comes from /etc/profile
2020-07-31T19:17:24 < mawk> ah no it's maybe not - or +, maybe I misremember it
2020-07-31T19:18:45 < mawk> you can do /usr/bin/env yourprogramgoeshere
2020-07-31T19:18:56 < mawk> but if they don't want you to use PATH, it's for obvious reasons
2020-07-31T19:19:05 < mawk> or rather, it's obviously because they have reasons
2020-07-31T19:19:20 < mawk> not because "linux is so fucking stupid"
2020-07-31T19:19:31 < mawk> people don't introduce changes like this with no reason and prior discussion
2020-07-31T19:19:35 < jadew> mawk, I think it's because is stupid, whatever reasons they have, they're wrong
2020-07-31T19:19:41 < mawk> lol
2020-07-31T19:20:03 < jadew> there's no reason why I wouldn't have access to system utilities in a script
2020-07-31T19:20:23 < jadew> the reason could be "because we're stupid and we designed it that way"
2020-07-31T19:20:41 < jadew> I'm gonna agree to that
2020-07-31T19:22:59 < jadew> jesus fuck...
2020-07-31T19:23:09 < jadew> my newly installed server JUST WENT TO FUCKING SLEEP
2020-07-31T19:23:53 < Steffanx> pebkac.
2020-07-31T19:24:07 < jadew> systemd[1]: Reached target Sleep.
2020-07-31T19:24:21 < jadew> Steffanx, I just installed it, it's the "server" variant
2020-07-31T19:24:34 < jadew> what kind of server goes to sleep?
2020-07-31T19:24:41 < jadew> a linux one
2020-07-31T19:25:44 < mawk> you pushed the sleep button
2020-07-31T19:25:51 < jadew> impossible
2020-07-31T19:25:55 < jadew> it's in the back of the unit
2020-07-31T19:26:00 < mawk> the cat did
2020-07-31T19:26:04 < jadew> don't have a cat
2020-07-31T19:26:11 < mawk> maybe the cat typed "systemctl sleep" on the keyboard
2020-07-31T19:26:14 < mawk> ah
2020-07-31T19:26:21 < Steffanx> its probably the lovely systemd auto sleep mode
2020-07-31T19:26:26 < mawk> that doesn't exist
2020-07-31T19:26:39 < Steffanx> Im pretty sure there is something in systemd to do that
2020-07-31T19:26:57 < mawk> there is infrastructure to trigger the various sleep levels, but I'm not aware of any automatic gadget
2020-07-31T19:27:41 < Steffanx> https://shallowsky.com/blog/linux/prevent-sleep-systemd.html (its older info but .. looks like the systemd to me)
2020-07-31T19:28:37 < mawk> yeah that's the login daemon thing for graphical sessions
2020-07-31T19:28:45 < mawk> I'm not sure it's enabled at all on server
2020-07-31T19:29:10 < Steffanx> idk
2020-07-31T19:29:22 < Steffanx> Lunix :P
2020-07-31T19:29:33 < jadew> it's ok, I can just reach in the back and press the button when I want people to visit my website
2020-07-31T19:29:51 < Steffanx> Who the fuck hosts a website from home anyway
2020-07-31T19:30:09 < jadew> what's the problem with that?
2020-07-31T19:30:13 < Steffanx> Its not 1999 anymore
2020-07-31T19:30:23 < jadew> it's cheaper and I have more control over it
2020-07-31T19:30:57 < Steffanx> Im not convinced its cheaper.
2020-07-31T19:31:28 < jadew> I had this server for many years
2020-07-31T19:31:34 < jadew> 7 to 10
2020-07-31T19:32:05 < jadew> and this is the first time I change something (the hdd)
2020-07-31T19:33:33 < jadew> comes to less than $9/mo for dedicated hosting
2020-07-31T19:33:47 < Steffanx> Nah whatever. If you enjoy it, i wont stop you
2020-07-31T19:33:48 < jadew> and I'll probably use it for many more years
2020-07-31T19:34:09 < jadew> I wouldn't use it for a service
2020-07-31T19:34:20 < jadew> but for random websites it's great
2020-07-31T19:40:50 < jadew> systemctl mask sleep.target suspend.target hibernate.target hybrid-sleep.target
2020-07-31T19:41:01 < jadew> that's the solution
2020-07-31T19:41:19 < mawk> I wouldn't call this a solution
2020-07-31T19:41:23 < mawk> you can still suspend the system
2020-07-31T19:41:29 < mawk> just don't have services that suspend your system
2020-07-31T19:41:43 < jadew> well, yeah, that's the point, no?
2020-07-31T19:44:56 < jadew> my biggest problem with linux is that even within a distribution, they don't stick to the same tools
2020-07-31T19:45:27 < jadew> which is probably why the firewall settings I had for the previous server, didn't work on the new install out of the box
2020-07-31T19:45:43 < jadew> so it's not like you can learn how to do things and then you're good for 10 years
2020-07-31T19:45:47 < jadew> it's going to change every freaking time
2020-07-31T19:47:14 < jadew> and it's all useless information
