2019-03-01T00:01:14 < Cracki> sigrok maybe :P
2019-03-01T00:01:34 < rajkosto> im not using a logic analyzer...
2019-03-01T00:01:46 < rajkosto> itmdump can do it but im not gonna bother
2019-03-01T00:03:22 < kakimir> yes
2019-03-01T00:03:44 < kakimir> you can do hard way, easy way or no way
2019-03-01T00:06:44 < Cracki> I just googled "aouexw" and google knew it meant "source"
2019-03-01T00:06:57 < rajkosto> yes iit knows one letter shifts
2019-03-01T00:07:11 < Cracki> one hand misaligned
2019-03-01T00:07:26 < kakimir> if code editor knew
2019-03-01T00:07:37 < kakimir> what I try to write too fast
2019-03-01T00:10:50 < bitmask> What is the difference between the short ones and longer ones? https://www.aliexpress.com/item/10pcs-lot-4mm-banana-binding-post-4mm-banana-socket-Free-shipping/32809739393.html

2019-03-01T00:11:59 < Cracki> the long ones have screws you can tighten?
2019-03-01T00:12:31 < Cracki> ah! those are for screwing on fork (?) terminals to it, in addition to banana
2019-03-01T00:13:01 < bitmask> you mean spade?
2019-03-01T00:13:05 < bitmask> on the back end?
2019-03-01T00:13:06 < Cracki> see pic 3, little eye in the metal body. you can stick wire in there and then screw it tight
2019-03-01T00:13:11 < Cracki> front end
2019-03-01T00:13:13  * banana eats Cracki
2019-03-01T00:13:18 < banana> WHO
2019-03-01T00:13:21 < Cracki> back end is two nuts
2019-03-01T00:13:21 < banana> DOTH SUMMON
2019-03-01T00:13:26 < bitmask> :P
2019-03-01T00:13:29 < banana> THE GREAT BANANA
2019-03-01T00:13:40 < banana> [lightning flashes in the distance]
2019-03-01T00:13:40 < bitmask> gimme yo plugs
2019-03-01T00:13:46  * banana plugs bitmask
2019-03-01T00:13:52 < Cracki> wow lewd
2019-03-01T00:13:55  * bitmask kinda likes it
2019-03-01T00:14:11 < Cracki> I knew the gf was a beard!
2019-03-01T00:14:49 < bitmask> alright I"ll just get the longer ones,  probably more options to work with
2019-03-01T00:15:35 < Cracki> apropos pissed off old bananas: https://pbs.twimg.com/media/D0X5orQWkAAQZaG.jpg:orig
2019-03-01T00:17:10 < Cracki> the long ones ive seen used as PSU terminals on those "fancy" breadboards that are glued onto sheet metal
2019-03-01T00:31:54 < rajkosto> thems animals, boss
2019-03-01T00:40:41 < bitmask> hmm DPS5015 (50v 15A) buck only is the same price as dph5005 (50v 5A) buck/boost
2019-03-01T00:42:23 < rajkosto> oh thats a newer version of the 3605 ?
2019-03-01T00:42:34 < rajkosto> pcb looks identical
2019-03-01T00:43:20 < rajkosto> the buck only is slightly cheaper
2019-03-01T00:43:29 < rajkosto> and has green pcb
2019-03-01T00:44:02 < rajkosto> efficiency of buck boost is way lower (85% vs 95%) so thats why the way lower current rating
2019-03-01T00:45:12 < bitmask> oh hmm
2019-03-01T00:45:43 < bitmask> is it lower efficiency when lowering voltage too?
2019-03-01T00:45:59 < bitmask> maybe I'll get the buck only version and upgrade to a higher voltage psu later
2019-03-01T00:46:21 < rajkosto> yeah its lower efficiency overall
2019-03-01T00:53:21 < rajkosto> https://images.sshnuke.net/2019-02-28_23-53-18_rbg37TRDM.png why have you forsaken me

2019-03-01T10:11:01 < kakimir> what is crc check of flash for?
2019-03-01T10:11:38 < kakimir> is it for when code accidentally fucks contents?
2019-03-01T10:11:49 < qyx> the flash can fuck itself too
2019-03-01T10:11:54 < kakimir> hmm
2019-03-01T10:12:07 < kakimir> so it's liek a good part of self test
2019-03-01T10:12:38 < qyx> some flashes do it regularly
2019-03-01T10:12:48 < qyx> like the samsung may-flash or whatever it was
2019-03-01T10:13:13 < qyx> but thats nand, it is ok in this case
2019-03-01T10:21:11 < kakimir> but I'm talking about flash like what is in AVR micro
2019-03-01T10:21:24 < kakimir> is it NAND shiets nowdays?

2019-03-01T12:55:32 < KolK> Hello, I have a problem with stm32 bootloader communication. I'm using PL2303 uart-usb converter, it is connected to usart3 on my stm32f446 nucleo board and boot0 pin is connected to vdd
2019-03-01T12:55:50 < KolK> I read in stm32 bootloader documentation
2019-03-01T12:56:19 < KolK> that I should send 0x7f sequence: start bit, 0x7F data bits, even parity bit and a stop bit
2019-03-01T12:56:58 < KolK> it looks like I should send 11bits
2019-03-01T12:57:04 < KolK> am I correct?
2019-03-01T12:57:35 < KolK> I don't understand thing that is called 0x7f data frame
2019-03-01T12:57:59 < KolK> I'm using this documentation https://bit.ly/2UgSjq8
2019-03-01T12:59:39 < KolK> So I have two questions: 1) how should I understand sth called '0x7f data frame', 2) can pl2303 produce any problems with communication? 
2019-03-01T13:00:04 < KolK> because now I'm sending just 0x7f byte, but I receive 0xff or 0xfe
2019-03-01T13:00:12 < KolK> and this is definitely not ACK
2019-03-01T13:00:59 < qyx> did you configure your serial port to even parity?

2019-03-01T13:36:16 < jadew> do SSRs get hot?
2019-03-01T13:36:49 < jadew> dongs, cool
2019-03-01T13:36:56 < jadew> it got there rather fast
2019-03-01T13:36:59 < jadew> glad you like it
2019-03-01T13:37:07 < dongs> im not sure how long its been here actually
2019-03-01T13:37:12 < dongs> i only go to that office once a month or someshit
2019-03-01T13:37:23 < dongs> jadew, they do if shittily driven
2019-03-01T13:37:52 < jadew> I'm looking for a more pro box to put it in
2019-03-01T13:37:54 < dongs> i was on some garbage project that drove them without using proper phase-sensing coupler
2019-03-01T13:37:54 < qyx> what does shittily driven mean
2019-03-01T13:38:05 < qyx> phase sensing coupler? wut?
2019-03-01T13:38:07 < dongs> qyx, switching them not on phase edges
2019-03-01T13:38:27 < qyx> idk if you know but most of the ssrs have that feature builtin
2019-03-01T13:38:28 < dongs> err zero crossing-sensing thing. sorry that
2019-03-01T13:38:40 < dongs> right, the shit these niggers used didnt
2019-03-01T13:38:48 < dongs> cuz cheap
2019-03-01T13:38:52 < qyx> and even then they are getting hot ion static conditions
2019-03-01T13:39:19 < qyx> eg. 1 am using 16A ssr to drive 750W pump and it is ~hot
2019-03-01T13:39:26 < qyx> without heatsinking of course
2019-03-01T13:39:40 < qyx> with a datasheet approved heatsing it could survive the rated 16 amp
2019-03-01T13:40:18 < qyx> idk, is it triac or what
2019-03-01T13:40:22 < qyx> probably
2019-03-01T13:40:35 < jadew> hmm, how do I know if it has zero crossing sensing?
2019-03-01T13:40:42 < jadew> I'll have to probe the output, isn't it?
2019-03-01T13:41:08 < qyx> just check the DS
2019-03-01T13:41:29 < qyx> but it depends what do you plan to use them for
2019-03-01T13:41:50 < qyx> for simple switching you want ZC
2019-03-01T13:42:01 < jadew> I want to drive my toaster oven
2019-03-01T13:42:08 < qyx> for some phase-cut regulation you don't want it

2019-03-01T14:20:27 < englishman> jadew: yes ssrs have significant Ron and usually need to be heatsinked
2019-03-01T14:23:30 < jadew> englishman, thanks
2019-03-01T14:24:04 < jadew> you think the zero-corssing issue would be significant if my PWM period is of about 2-3 seconds?
2019-03-01T14:24:36 < jadew> would be like... 1 bad cycle in 150
2019-03-01T14:24:58 < jadew> actually, I should check the datasheet, maybe I don't have to worry about it at all
2019-03-01T14:26:25 < jadew> looks like they have zero-crossing detection
2019-03-01T14:27:15 < qyx> so less disturbances, much switching, better electricity, wow
2019-03-01T14:27:21 < qyx> cleaner world
2019-03-01T14:27:43 < qyx> I would use ZC, 2-3 sec is not a problem for heating
2019-03-01T14:29:01 < jpa-> SSRs do get hot due to just the voltage drop also, about 1-2 volt

2019-03-01T14:29:21 < jadew> really, that's all they drop?
2019-03-01T14:30:01 < jadew> actually, that still means about 10W @ 10A
2019-03-01T14:30:13 < jpa-> yeah, it's rather high compared to normal relays
2019-03-01T14:32:56 < qyx> 10W is enough to fry it
2019-03-01T14:33:06 < jadew> yeah
2019-03-01T14:33:13 < jadew> it will need active cooling
2019-03-01T14:33:23 < jadew> or a serious heatsink

2019-03-01T15:05:18 < KolK> hmm, in my case the problem may be caused by pl2303
2019-03-01T15:05:50 < KolK> when I turned off stm and send anything through serial
2019-03-01T15:05:58 < KolK> I receive 0x00

2019-03-01T15:06:23 < KolK> my baudrate is 9600
2019-03-01T15:08:20 < Cracki> get a logic analyzer or oscilloscope and look at the data line
2019-03-01T15:08:32 < dongs> > pl2303
2019-03-01T15:08:33 < dongs> yeah, definitely
2019-03-01T15:09:10 < Cracki> you should also make sure to open that usb com port with the right settings (9600, parity, stop bit?)
2019-03-01T15:14:29 < KolK> Cracki: I'm sure that I have 9600, parity even and stop bit 
2019-03-01T15:14:41 < KolK> dongs: should cp2101 be better?

2019-03-01T15:31:53 < Rajko> whats the difference between 128 bytes of RTC registers vs 2K of battery backed sram
2019-03-01T15:32:02 < PaulFertser> KolK: is it possible you need to power some pl2303's pin with 3.3V so hat it can actually drive its tx?
2019-03-01T15:32:05 < dongs> he way you access it
2019-03-01T15:32:35 < Rajko> does using only 128byte drain the vbat less
2019-03-01T15:32:40 < dongs> nope
2019-03-01T15:33:17 < PaulFertser> KolK: VDD_232
2019-03-01T15:35:37 < Rajko> dongs, so the only advantage of 128bytes is that it can be erased on tamper
2019-03-01T15:36:13 < qyx> and backup sram no?
2019-03-01T15:36:21 < Rajko> https://images.sshnuke.net/2019-03-01_14-36-19_4rX8xnN9C.png
2019-03-01T15:36:32 < Rajko> here it does say that the additional sram takes up vbat power if enabled
2019-03-01T15:37:02 < dongs> oh
2019-03-01T15:37:05 < dongs> well then it does
2019-03-01T15:37:09 < dongs> i figured it'd be in same domain
2019-03-01T15:45:00 < zyp> same domain, but enabled or not matters
2019-03-01T15:45:21 < zyp> backup regs are part of rtc block, backupsram is independent

2019-03-01T19:15:33 < zyp> yeah
2019-03-01T19:15:37 < englishman> will you have a heated gravel driveway?
2019-03-01T19:15:43 < zyp> haha, no
2019-03-01T19:16:26 < kakimir> he will charge or heat his car
2019-03-01T19:17:27 < zyp> I've concluded that putting a charger next to the window on the wall and running a cable to it is gonna look kinda ugly and not be all that convenient
2019-03-01T19:18:11 < zyp> and I'm planning to build a stand for the garbage cans on the side towards the road, so I figure it might be more convenient to just put the charger there
2019-03-01T19:18:46 < zyp> and if I wanna do that, I better run the conduit now before they come and cover the entire area with asphalt
2019-03-01T19:19:29 < zyp> kakimir, technically the wife's car, but yes
2019-03-01T19:20:04 < zyp> having power over there would also be convenient if I wanna put up some light poles or something on the fence
2019-03-01T19:20:16 < englishman> here, conduit below vehicles has to be in a solid tube or real deep
2019-03-01T19:20:31 < zyp> what do you mean by solid?
2019-03-01T19:20:47 < englishman> like, protective plastic
2019-03-01T19:20:55 < englishman> so you can hit it with a shovel
2019-03-01T19:21:10 < zyp> this is dualwalled conduit, designed for underground use

2019-03-01T19:58:49 < qyx> wago 2273 for solid
2019-03-01T19:58:50 < qyx> I use
2019-03-01T19:59:10 < jadew> I guess it'll have to wait till tomorrow, cuz I can't get in time to any hardware store
2019-03-01T19:59:13 < qyx> and 221 for stranded
2019-03-01T19:59:54 < englishman> in my toaster I didn't need any joins, all terms were at screw terms
2019-03-01T20:00:14 < englishman> soldered +kapton+shrunk maybe
2019-03-01T20:00:46 < jadew> is that safe tho?
2019-03-01T20:00:59 < englishman> you didn't specify safe
2019-03-01T20:01:20 < jadew> :)
2019-03-01T20:02:08 < jadew> I'll wait 'till tomorrow, see if I can find something proper for the job
2019-03-01T20:03:01 < antto> this is what i used for mains, there are variants with a plastic lid on the top too.. https://i.imgur.com/nKaMhLq.jpg
2019-03-01T20:03:20 < jadew> I'm going to mount the SSRs on the bottom sheet of the case
2019-03-01T20:03:26 < jadew> hope that's going to be enough
2019-03-01T20:03:42 < jadew> the current through each of them is going to be below 3.5A
2019-03-01T20:03:59 < jadew> so they'll have to dissipate about 5 Watts each
2019-03-01T20:04:09 < jadew> I think that's going to be sufficient
2019-03-01T20:04:29 < jadew> antto, yeah, but I don't have a board
2019-03-01T20:04:39 < antto> oh.. oops
2019-03-01T20:04:54 < jadew> I just need to get from one wire to 4
2019-03-01T20:05:11 < jadew> maybe 3... not sure yet
2019-03-01T20:05:31 < jadew> it has a convection fan and a light and I'd like to control those separately too
2019-03-01T20:09:03 < jadew> antto, that board looks ready to snap at any time
2019-03-01T20:09:14 < jadew> you really went to town with those slots
2019-03-01T20:09:15 < antto> i snapped it already ;P~
2019-03-01T20:09:20 < jadew> hah
2019-03-01T20:09:42 < jadew> I'm surprised the guys at the factory didn't do that for you, thinking they're two separate boards
2019-03-01T20:09:59 < jadew> or are they?
2019-03-01T20:10:48 < antto> they did asked me something in engrish, i think they were asking if i want them to put drills in that spot..
2019-03-01T20:11:10 < antto> it's one board which can be snapped into two, optionally
2019-03-01T20:11:19 < jadew> got it
2019-03-01T20:12:14 < jadew> that 5W resistor is intriguing me... what does that side do?

2019-03-01T20:12:36 < jadew> power supply?
2019-03-01T20:12:42 < antto> yeah

2019-03-01T20:14:04 < kakimir> I'm inna bus
2019-03-01T20:14:07 < kakimir> need pumps
2019-03-01T20:14:32 < jadew> want to show off your legs?
2019-03-01T20:15:56 < kakimir> third leg
2019-03-01T20:15:59 < antto> kakimir get a knife and cut the tyre
2019-03-01T20:16:37 < antto> then volunteer to pump up the spare tyre ;P~
2019-03-01T20:16:42 < kakimir> hmm that would not be a good pump
2019-03-01T20:17:16 < antto> okay.. how about.. flood your house, and then start pumping the water out?
2019-03-01T20:18:07 < kakimir> antto: hmm is that fuse F2 okay?
2019-03-01T20:19:01 < antto> i haven't populated it yet
2019-03-01T20:20:43 < jadew> this looks the same like that wago stuff: https://www.bricodepot.ro/electrice/elemente-de-conexiune/set-10-conectori-pentru-cablu-3-poli.html

2019-03-01T22:24:29 < rajkosto> 2835 is better
2019-03-01T22:24:41 < rajkosto> they are dimensions in millimeters are they not
2019-03-01T22:24:41 < bitmask> I didnt say all were too small
2019-03-01T22:24:51 < rajkosto> so 1616 is quite a bit larger than a 0402

2019-03-01T23:10:13 < aandrew> something like serila output to a vt100 serial program but lets me have a couple scrolling regions and a command input area

2019-03-01T23:11:50 < Ultrasauce> wonder how easily ncurses would port
2019-03-01T23:12:40 < aandrew> I haven't used an os/360 before
2019-03-01T23:12:53 < aandrew> Ultrasauce: ncurses is *huge* and not suited for serial terminals I don't think
2019-03-01T23:13:16 < aandrew> vt100 gives you some interactivity (eg I can ask the serial program what the screen size is, and you can define a scroll region but it's tedious as hell)
2019-03-01T23:14:31 < BrainDamage> ncurses uses alternate mode
2019-03-01T23:14:52 < BrainDamage> ... like every interactive terminal application there is
2019-03-01T23:15:20 < BrainDamage> but you'll still end up reinventing your own subset of ncurses for your repl
2019-03-01T23:15:27 < Thorn> I've seen a 'how to write a ncurses based text editor' tutorial
2019-03-01T23:15:39 < BrainDamage> because the moment you add scrolling, you're pretty much adding a virtual terminal
2019-03-01T23:15:49 < Thorn> no, not even ncurses, they used vt100 commands directly
2019-03-01T23:16:02 < BrainDamage> and the only way to get it light is to restrict to a specific subset of commands
2019-03-01T23:17:12 < Thorn> I think this was it https://viewsourcecode.org/snaptoken/kilo/

2019-03-02T00:06:47 < Cracki> so I have a dc motor and driver, but the current sensing is shit (~100 mA/LSB) so I was thinking I could estimate torque/current from speed and applied voltage since that's linearly proportional and might only need a little calibration to get me a value in proper units
2019-03-02T00:07:06 < Cracki> has anyone here done that and could share some anecdotes/experience?
2019-03-02T00:09:05 < Cracki> I was also thinking to estimate the load's mass (which varies during operation) from acceleration and torque... F=ma => 1/m = a/F, which sounds doable
2019-03-02T00:11:03 < BrainDamage> if your load varies your system is not linear anymore
2019-03-02T00:11:22 < BrainDamage> and you already have one integral inbetween
2019-03-02T00:11:26 < BrainDamage> what kind of precision can you accept?

2019-03-02T00:13:42 < upgrdman> heh, that was easy. tmobile throttles tethering to ~500kbps by comparing packet TTLs. having my PC use a TTL of 65 does the trick. not throttled. yay
2019-03-02T00:14:33 < Cracki> eh, the old version apparently managed to apply too much current so boss merely wants a current limit. that cheap current sensing would be acceptable but I'm looking at what more can be done with some (simple) ideas
2019-03-02T00:14:40 < Cracki> wat
2019-03-02T00:14:50 < Cracki> oh boy
2019-03-02T00:15:10 < Cracki> m is varying _slowly_
2019-03-02T00:16:17 < Cracki> so doing a moving/exponential average of 1/m from a/F might be a useful value to have for a control loop
2019-03-02T00:16:23 < BrainDamage> periocally sampling the new value gives you a frequency response with sin(kx) where k is 2pi/sampling_distance, where generally you want the first null to fit your system bandwith
2019-03-02T00:16:47 < BrainDamage> because it's the fourier transform of 2 opposite deltas
2019-03-02T00:17:06 < BrainDamage> in your case the bandwith is the mass variance
2019-03-02T00:17:40 < Cracki> load might gain 5 grams per second at maximum
2019-03-02T00:18:00 < Cracki> range of maybe 0.1kg to 5-10 kg
2019-03-02T00:18:50 < Cracki> it's a cylinder, so from mass I would derive diameter, which would be an interesting value as well :P
2019-03-02T00:19:35 < BrainDamage> so find the ke of your motor, and translate that to the electrical value, you'll get mass variance -> current variance with the ke, and times the builtin resistance the induced voltage
2019-03-02T00:19:50 < Cracki> hm
2019-03-02T00:20:11 < BrainDamage> assuming that the mechanical pole is dominant factor, at 5g/s it should very well be

2019-03-02T02:08:46 < ds2> so force is the rate of change of momentum
2019-03-02T02:08:50 < mawk> product of mass and speed sorry
2019-03-02T02:08:52 < BrainDamage> dP/dt is the general formula, works even in relativity
2019-03-02T02:08:54 < mawk> yeah
2019-03-02T02:09:06 < BrainDamage> it reduces to ma iff m is constant
2019-03-02T02:09:10 < ds2> seem to recall that is always called it with some greek letter 
2019-03-02T02:09:13 < mawk> but since mass is constant most of the time you can simplify F = dp/dt to F = m·a
2019-03-02T02:09:25 < mawk> no it's usually p
2019-03-02T02:09:28 < mawk> never seen it with a greek letter
2019-03-02T02:09:54 < ds2> or maybe it is the angular version... *shrug* too many decades since I worked with that :D
2019-03-02T02:11:53 < mawk> the angular version is with a L and a fancy M
2019-03-02T02:13:12 < mawk> d(OM∧p)/dt = OM ∧ F
2019-03-02T02:13:38 < mawk> OM∧F is fancyM
2019-03-02T02:13:45 < mawk> \mathcal{M}

2019-03-02T07:21:34 < pennTeller> what is the case according to you as to why they are both valid?
2019-03-02T07:21:47 < karlp> you're obviously asking because you eitehr want justificaiton to keep doing what you'r edoing, or because you want justification for changing.
2019-03-02T07:22:03 < karlp> why would a random person on the internet's opinion be any more useful to you? :)

2019-03-02T08:52:56 < jpa-> if your programming team has size of one, you can't really expect to produce good software for safety critical purposes; better try to design the system so that software is not critical
2019-03-02T08:55:32 < dongs> good1
2019-03-02T08:55:34 < dongs> where's that wisdom from

2019-03-02T08:55:58 < dongs> lols
2019-03-02T08:57:37 < pennTeller> jpa-, I am curious as to why a team of one cannt expect to produce good software for critical purposes
2019-03-02T08:57:55 < jpa-> pennTeller: because people make mistakes, and it's hard to catch your own mistakes
2019-03-02T08:58:58 < pennTeller> jpa-, I see, that makes sense.

2019-03-02T09:23:39 < PaulFertser> A question implying that a person who doesn't know that there's no such thing as "arduino language" is going to write software for a critical machinery sounds really worrysome.
2019-03-02T09:25:52 < jadew> maybe he's planning 5 years ahead
2019-03-02T09:26:07 < jpa-> arduino language does differ from c++ by the automatic addition of prototypes

2019-03-02T09:28:21 < jadew> ah
2019-03-02T09:29:03 < jadew> I thought it's some macro shit they added
2019-03-02T09:29:57 < jadew> what happens if you define it in a different file?
2019-03-02T09:30:02 < jadew> does it still work?
2019-03-02T09:40:57 < PaulFertser> jpa-: yes, but I can't call that a "language feature", and it's somehow underspecified afair.
2019-03-02T09:41:40 < PaulFertser> jadew: yes, it somehow preprocesses all the files in the project to auto-create prototypes. And probably add extern global data definitions. Sick shit.
2019-03-02T09:43:48 < PaulFertser> Qt used to have that moc preprocessor but it doesn't make it another language I'd say.

2019-03-02T09:58:51 < dongs> jpa-: thats cuz they run some shitty sed script beforehand and search for function signatures and prepend them all at start
2019-03-02T09:59:02 < dongs> which also means you can't do shit like defining  your own types and stuff
2019-03-02T09:59:05 < dongs> that go into function args
2019-03-02T09:59:13 < dongs> cuz the p repended list will be ahead of the definmitions
2019-03-02T09:59:17 < dongs> arduino is truly fucking aids
2019-03-02T10:00:11 < dongs> which is why most "serious" attempts at retarduino projects have a single .ino that just has a fuckyuo() { } in it and the rest of the code goes into cpp/h that at least avoids being cancer'd by the scripts

2019-03-02T10:59:43 < PaulFertser> dongs: haha, yes, I use it by default but I also often add !g to the request, so I can actuall compare the services. Surprisingly, DDG is often giving me more relevant results. 
2019-03-02T11:00:26 < PaulFertser> DDG is kind of annoying as they promised to avoid "guessing" and "correcting" the search requests and now they actually do all that.
2019-03-02T11:01:30 < dongs> google is quite annoying when it searches for synonyms of something
2019-03-02T11:01:45 < PaulFertser> Yes, and ddg promised to not do that.
2019-03-02T11:01:48 < dongs> like you search for jewbunto and it will include results with 'lunix' in it
2019-03-02T11:01:49 < dongs> (for example)
2019-03-02T11:02:02 < dongs> it will even bold the shit it thinks is "related" to the original query
2019-03-02T11:02:10 < dongs> unless you ""' it specially
2019-03-02T11:03:12 < PaulFertser> Exactly
2019-03-02T11:04:30 < PaulFertser> I like ddg because I can search with it, google, google images, wikipedia, wiktionary all from the same interface, I just add "!wiktionary" or "!gimages" right in the request.

2019-03-02T14:32:30 < antto> google doesn't care what you want to search for

2019-03-02T14:45:58 < englishman> idk about awful. search before google was awful in general
2019-03-02T14:46:12 < englishman> and it's better than that
2019-03-02T14:46:21 < englishman> i'd say: pretty bad
2019-03-02T14:47:14 < Steffanx> for some reason i tend to not find with the duck what im looking for, while i can find it with the google.
2019-03-02T14:49:31 < rajkosto> because bing results suck.
2019-03-02T14:49:47 < rajkosto> with google the thing you want will likely be near the top fo the first page
2019-03-02T14:49:54 < rajkosto> with bing you will just get unrelated spammy nonsense
2019-03-02T14:52:25 < BrainDamage> yup, that's what you get for the lack of profiling, you get a generic result, you may like it or not
2019-03-02T14:52:39 < Steffanx> true :P
2019-03-02T14:55:31 < rajkosto> not just profiling

2019-03-02T14:55:44 < rajkosto> couldnt find shit

2019-03-02T15:41:59 < BrainDamage> yahoo and altavista were the dominant engines before google, but there were hundreds of them
2019-03-02T15:42:35 < BrainDamage> unlike the others, google had a clean page and somewhat worked
2019-03-02T15:42:48 < dongs> there was also the aol webcrawler

2019-03-02T15:51:23 < kakimir> I see chinaman didn't bother to input cap these optical converters
2019-03-02T15:51:37 < kakimir> should I populate them cap footprints
2019-03-02T15:55:48 < kakimir> I wonder why these have 5VDC input plug
2019-03-02T15:55:56 < kakimir> there is AM1117 inside
2019-03-02T15:56:54 < kakimir> maybe it's the pd

2019-03-02T16:30:55 < aandrew> basically I fucked up the footprint (mirrored left-right) on that digitizer board so I can't directly plug the PoE/ethernet board on to it
2019-03-02T16:31:08 < aandrew> so I created this stupid simple board to give me access to ethernet and be able to power it
2019-03-02T16:31:18 < aandrew> I just included the same I2C expander that hte PoE board has
2019-03-02T16:31:22 < aandrew> the funny part is
2019-03-02T16:31:28 < aandrew> the pinout is now right

2019-03-02T16:31:48 < aandrew> yes it is
2019-03-02T16:32:07 < aandrew> that is a pretty huge design though so some dumb mistakes were bound to creep in
2019-03-02T16:32:09 < dongs> its almost as if you were using kikecad
2019-03-02T16:32:15 < aandrew> a proper design review would have caught it

2019-03-02T16:33:07 < dongs> i can't see signals connecting in 3d view
2019-03-02T16:33:17 < aandrew> this was uberrush, I had it laid out on monday and had the board in my hand on friday
2019-03-02T16:33:31 < jadew> any ideas if this is dangerous to work with? https://4.imimg.com/data4/KH/HQ/MY-323036/fiberglass-insulated-cables-500x500.jpg

2019-03-02T16:33:37 < dongs> but yeah when i have sockets that need to mate i'll print or draw them on pieces of paper and stack them the way they will be stacked to make sure im not fuckin shit up

2019-03-02T16:34:04 < kakimir> jadew: dangerous in what sense?
2019-03-02T16:34:20 < aandrew> jadew: I suspect it has the same concerns as any other fiberglass work -- those frayed ends will put fibres into the air that you can breathe and get in your lungs
2019-03-02T16:34:26 < jadew> kakimir, stripping the fiberglass may leave some fiberglass in the air
2019-03-02T16:34:31 < aandrew> but no frayed ends and you're not bending the wire constantly = safe enough
2019-03-02T16:34:40 < kakimir> jadew: 1st world problems
2019-03-02T16:34:59 < kakimir> just breathe in before cutting
2019-03-02T16:35:26 < kakimir> I only wonder how much there is FR4 in my lungs
2019-03-02T16:36:15 < rajkosto> dangerous amounts
2019-03-02T16:36:22 < rajkosto> i used to hand drill 300+ holes in fr4
2019-03-02T16:36:23 < kakimir> I can feel it
2019-03-02T16:36:56 < BrainDamage> get a pc fan and a drier flexible tubing

2019-03-02T16:37:13 < aandrew> ^^ 
2019-03-02T16:37:17 < aandrew> this is my question
2019-03-02T16:37:42 < aandrew> I also wonder how much nerve damage I have from playing with mercury with bare hands as a kid
2019-03-02T16:37:55 < aandrew> I mean I don't have tremors or anything and that was literally like 35y ago
2019-03-02T16:38:00 < kakimir> none
2019-03-02T16:38:01 < aandrew> but the FR4 is pretty recent
2019-03-02T16:38:02 < dongs> haha.
2019-03-02T16:38:34 < dongs> aaJEW, i once broke a huge mercury thermometer, took its contents and filled an empty wristwatch shell with it and brought that to kindergarden
2019-03-02T16:38:41 < kakimir> sometime I use big angle grinder to cut a lot of fr4 quickly
2019-03-02T16:38:50 < sync> as long as you don't snort the fr4 dust you should be fine
2019-03-02T16:39:05 < dongs> and was wearing that shaking it around and watching shit swirl around under the glass
2019-03-02T16:39:32 < dongs> then it got too hot from being on wrist and random bits of it were oozing out

2019-03-02T16:40:12 < kakimir> okay we have a winner
2019-03-02T16:40:49 < aandrew> dongs: I got you beat there. I took apart like a dozen mercury switches from thermostats I found in the trash (I used ot live by a kind of industrial/commerical area so would do a LOT of dumpster diving)
2019-03-02T16:41:21 < kakimir> using poisonous materials as wearable item
2019-03-02T16:41:21 < aandrew> the resulting puddle of mercury I literally smashed with a hammer on the garage floor, then swept all the little bits back with my hands and did it over and over 
2019-03-02T16:41:31 < aandrew> then of course went back in and ate lunch without washing my hands
2019-03-02T16:41:41 < aandrew> I never washed my hands unless told 
2019-03-02T16:41:42 < dongs> awesome
2019-03-02T16:41:46 < aandrew> that was a LOT of fun
2019-03-02T16:41:50 < aandrew> mercury is fucking cool
2019-03-02T16:42:24 < Adluc> aandrew: and effects on your body?
2019-03-02T16:42:33 < rajkosto> aandrew, its fine
2019-03-02T16:42:49 < rajkosto> people in the dark ages would gulp mercury down as a refreshing drink
2019-03-02T16:50:01 < aandrew> Adluc: that's the question. I honestly don't think it had any effect; perhaps the hazards of temporary exposure like that are overstated (in fact I'm sure of it)
2019-03-02T16:57:38 < BrainDamage> it depends on the bioavailability
2019-03-02T16:58:12 < BrainDamage> eg eating lead vs lead acetate
2019-03-02T16:59:55 < aandrew> right
2019-03-02T17:00:07 < aandrew> and I don't think that mercury in that form is very bioavailable
2019-03-02T17:00:40 < PaulFertser> Mercury was also used to treat syphilis.
2019-03-02T17:01:11 < aandrew> perhaps that was the best of two evils
2019-03-02T17:06:06 < PaulFertser> "introduced the treatment of neurosyphilis with fever therapy by infecting the patient with malaria, then treating the malaria with quinine."

2019-03-02T22:44:45 < R2COM> sata cable for regular high speed io?
2019-03-02T22:45:23 < R2COM> samtec has a nicer (and proly more cheap) solutions developed exactly for that
2019-03-02T22:48:46 < rajkosto> scrts, no, the twinax coaxes are straight through
2019-03-02T22:49:11 < scrts> I want to pass SGMII signal
2019-03-02T22:49:13 < scrts> so 1Gbps
2019-03-02T22:49:24 < scrts> not too high speed, but not slow either
2019-03-02T22:49:44 < scrts> SATA connectors are $0.66
2019-03-02T22:49:49 < scrts> cables are probably the same

2019-03-02T22:52:32 < rajkosto> why tho
2019-03-02T22:52:34 < Ultrasauce> if only sgmii could be transformed into some sort of robust signal that can be transmitted over a hundred metres over commodity cable
2019-03-02T22:52:44 < rajkosto> just wire them knowing its straight through
2019-03-02T22:52:57 < rajkosto> or require a bend in the cable (connector would be rotated 180 deg then)
2019-03-02T22:53:07 < scrts> rajkosto: if I want to connect 2 same boards
2019-03-02T22:53:17 < scrts> one has to be set as "transmitter" and another as "receiver

2019-03-02T22:54:19 < scrts> Ultrasauce: usually SGMII goes into SFP module
2019-03-02T22:54:23 < scrts> for optical transmission
2019-03-02T22:54:34 < scrts> so I could transmit that signal over a mile

2019-03-03T01:01:18 < oats> hello. I'm trying to use stlink and gdb together and I'm running into an issue where gdb doesn't show the source anymore when I run 'target remote localhost:4242'
2019-03-03T01:01:57 < zyp> go on
2019-03-03T01:02:11 < oats> I apologize if this isn't an appropriate channel to ask this in, I just thought I'd try here first
2019-03-03T01:02:42 < zyp> asking is fine, but you have to provide more information
2019-03-03T01:03:33 < zyp> so far it amounts to «it doesn't work» and that's not much to go on
2019-03-03T01:03:53 < oats> I can provide more context
2019-03-03T01:04:06 < oats> I'm trying to compile and debug a simple libopencm3 example program
2019-03-03T01:04:18 < oats> using their makefile
2019-03-03T01:04:32 < oats> `file` tells me the file has debug symbols
2019-03-03T01:05:03 < oats> and before I connect gdb to stlink, the source shows
2019-03-03T01:05:07 < oats> (I'm using --tui, btw)
2019-03-03T01:05:45 < oats> but after I run the target command, it just shows "[ No source available ]"
2019-03-03T01:05:56 < oats> the output from stlink says gdb successfully connected
2019-03-03T01:06:15 < zyp> are you using texane/stlink?
2019-03-03T01:06:19 < oats> yes
2019-03-03T01:06:37 < oats> `st-link -m`
2019-03-03T01:06:43 < zyp> I believe that's fairly obsolete, my impression is that most stlink users are using openocd nowadays
2019-03-03T01:06:57 < zyp> not that this is necessarily related to your problem, but still
2019-03-03T01:06:58 < oats> the same thing happened with openocd
2019-03-03T01:07:09 < oats> here's the gdb command I'm using
2019-03-03T01:07:13 < oats> arm-none-eabi-gdb -q --tui --eval-command="target remote localhost:4242" miniblink.elf
2019-03-03T01:07:31 < zyp> you should probably replace remote with extended-remote
2019-03-03T01:08:09 < oats> no dice
2019-03-03T01:08:13 < zyp> well
2019-03-03T01:08:15 < oats> what's the difference?
2019-03-03T01:08:43 < zyp> more features, not sure the old remote protocol allows loading
2019-03-03T01:08:52 < zyp> anyway
2019-03-03T01:09:29 < zyp> I'm not familiar with gdb-tui, but are you sure you're not just misinterpreting the message and that it's actual normal behavior?
2019-03-03T01:10:15 < oats> ¯\_(ツ)_/¯
2019-03-03T01:10:30 < zyp> I figure if you connect to a target running different code, gdb might read a $pc value you don't have symbols for, and as there's no symbol, tui can't find any corresponding source either
2019-03-03T01:10:50 < zyp> or have you actually written this code to the target?
2019-03-03T01:12:17 < oats> do I need to write it first before starting openocd/gdb?
2019-03-03T01:12:44 < zyp> no, if you use extended-remote, you can do it with the «load» command

2019-03-03T01:16:23 < oats> oh my god I'm an idiot
2019-03-03T01:16:29 < oats> reset_handler () at ../../cm3/vector.c:67
2019-03-03T01:16:34 < oats> first line gdb printed
2019-03-03T01:16:49 < oats> it starts in the reset_handler, and it has no debug info for that function
2019-03-03T01:16:55 < oats> so
2019-03-03T01:17:03 < oats> break main<RET>
2019-03-03T01:17:05 < oats> continue<RET>
2019-03-03T01:17:07 < zyp> uh
2019-03-03T01:17:28 < zyp> obviously it has debug info when it can tell you it's in reset_handler at vector.c:67
2019-03-03T01:17:36 < zyp> that's literally what debug info is
2019-03-03T01:19:53 < zyp> it's probably a matter of file paths, ../../cm3/vector.c sounds like it's relative to some directory in the libopencm3 tree, which is probably wherever that file was built
2019-03-03T01:20:11 < zyp> and now you're standing in your project tree instead
2019-03-03T01:20:15 < zyp> or an example or whatever
2019-03-03T01:20:52 < oats> hmm

2019-03-03T01:25:48 < zyp> adding the relevant dirs to the source search path would probably help

2019-03-03T01:30:58 < zyp> yeah, seems like libopencm3 builds all sources standing inside the variant dir
2019-03-03T01:31:34 < zyp> so for stm32f4, it'd build from libopencm3/lib/stm32/f4/ and consequently all source paths in the debug symbols will be relative to that dir

2019-03-03T02:04:54 < kakimir> ye
2019-03-03T02:09:30 < kakimir> lets try another power supply to another one of them
2019-03-03T02:10:26 < zyp> what's the problem? media converters should be fairly dumb so I don't see why it shouldn't keep up with line rate
2019-03-03T02:11:30 < zyp> hmm, apparently that QCA8334 is actually a switch
2019-03-03T02:11:53 < zyp> so it's essentially a two port switch
2019-03-03T02:12:11 < zyp> but still, switches should do line rate
2019-03-03T02:14:59 < kakimir> another one has FDX line on
2019-03-03T02:15:02 < kakimir> another one doesn't
2019-03-03T02:15:23 < kakimir> performace is about 10M to one direction and 4M to another
2019-03-03T02:16:00 < zyp> should have done like I suggested and just gotten some switches with sfp ports instead of dicking around with shitty converters
2019-03-03T02:16:22 < kakimir> aand.. iperf in one direction is 20M and to another 200k
2019-03-03T02:19:23 < kakimir> I just switch back to old adapters
2019-03-03T02:19:30 < kakimir> those are 100M

2019-03-03T05:03:21 < R2COM> and i know why...cuz there is no competition at all
2019-03-03T05:03:25 < R2COM> except couple companies
2019-03-03T05:03:38 < R2COM> so they dont work hard on making it better they just dont care
2019-03-03T05:04:45 < scrts> zyp: playing around with 88Q5050
2019-03-03T05:05:35 < scrts> it's ethernet switch, but 5x100BASE-T1, 1x100BASE-TX, 2xRGMII & 1xSGMII
2019-03-03T05:05:55 < dongs> sounds like marvell part
2019-03-03T05:05:59 < scrts> it is
2019-03-03T05:06:08 < dongs> how were you a ble to get any kind of docs or even buy the chip
2019-03-03T05:06:18 < scrts> avnet has the chip
2019-03-03T05:06:24 < scrts> docs is difficult..
2019-03-03T05:06:34 < dongs> hmm, has M7
2019-03-03T05:06:34 < scrts> got a copy from some source
2019-03-03T05:06:36 < dongs> interesting
2019-03-03T05:06:45 < dongs> in a switch huh
2019-03-03T05:06:53 < dongs> yeah so you're helping marvel be cunts
2019-03-03T05:06:54 < scrts> I will try to make it unmanaged 1st
2019-03-03T05:07:05 < dongs> by accepting their policy of being cuts with docs
2019-03-03T05:07:07 < dongs> er cunts
2019-03-03T05:07:07 < scrts> well, they're cunts fo sho
2019-03-03T05:07:17 < scrts> because I can't get docu easily myself
2019-03-03T05:07:49 < scrts> on the other hand - I don't see simple alternatives so far
2019-03-03T05:08:44 < R2COM> how much does it cost
2019-03-03T05:09:11 < MrMobius> R2COM, what currency do they use in dongistan?
2019-03-03T05:09:29 < R2COM> shekels
2019-03-03T05:11:54 < scrts> R2COM: almost 30 bux
2019-03-03T05:12:01 < scrts> 1 piece
2019-03-03T05:12:57 < MrMobius> R2COM, that is about 350 potatoes
2019-03-03T05:21:11 < scrts> P.S. did anyone try to do something with LoRa?
2019-03-03T05:22:54 < R2COM> isnt that shit only a low data rate stuff at longer ranges?
2019-03-03T05:23:44 < scrts> yeah
2019-03-03T05:24:26 < scrts> but if you need to send like 5 bytes for temperature reading - should be OK
2019-03-03T05:24:38 < R2COM> you  need to send 5 bytes on 10km?
2019-03-03T05:25:26 < R2COM> cuz if its much less distance then why need lora in a first place
2019-03-03T05:26:00 < scrts> I've been contacted by one lad
2019-03-03T05:26:17 < scrts> he was like: hey I Have a bunch of refrigerators about 5 miles away
2019-03-03T05:26:26 < scrts> and if one dies - I need to throw out all the shit
2019-03-03T05:26:49 < scrts> I'd rather know before it thawns 
2019-03-03T05:27:11 < scrts> 1st thing came to my mind was lora sensor as he said there's no internet
2019-03-03T05:27:26 < scrts> and if the power goes out - it should run on a battery
2019-03-03T05:27:59 < R2COM> that stuff in order to avoid FCC must be used in premade modules, rite?
2019-03-03T05:28:24 < scrts> good question
2019-03-03T05:28:29 < scrts> I'd guess so
2019-03-03T05:28:45 < scrts> and I wonder if no license is needed, meaning it operates in license free frequency
2019-03-03T05:30:14 < R2COM> i think for usa its 915mhz
2019-03-03T05:36:34 < englishman> Lora is great
2019-03-03T05:36:49 < englishman> lorawan is even better

2019-03-03T15:31:16 < englishman> did it pop out of a hatch
2019-03-03T15:32:13 < rajkosto> it was disturbed when they reached under the seats for the cargo

2019-03-03T15:59:37 < kakimir> zyp: found the problem
2019-03-03T15:59:56 < kakimir> ubiquiti had 100 Full selected instead of 10/100 auto
2019-03-03T16:00:55 < kakimir> so apparently there was some issue because of that but when I changed ubiquiti to 10/100 auto FDX led lit up in the converter
2019-03-03T16:01:17 < kakimir> and data rates were improved dramatically
2019-03-03T16:02:43 < kakimir> there is still an issue but now data rates are at usable level
2019-03-03T16:02:58 < kakimir> another end converter is at 1000
2019-03-03T16:03:09 < kakimir> another end is at 100 because of ubiquiti
2019-03-03T16:03:18 < kakimir> that seems to cause some issue to data rates
2019-03-03T16:03:59 < kakimir> but when I place my laptop to place of that ubiquiti WDS man it goes fast
2019-03-03T16:04:20 < kakimir> both ends are then 1000 - 1000
2019-03-03T16:05:34 < kakimir> I don't know how fast because another machine running iperf is in wireless network but got at least close to 200Mbps

2019-03-03T19:46:51 < PaulFertser> Ok, DDG superiority example now. Purpose: find devboard schematics; Request: avr-iot wg; DDG result: 3rd link; Google result: not present on first page.
2019-03-03T19:51:19 < antto> google was too busy corelating yer tracking data
2019-03-03T19:51:26 < antto> >:)
2019-03-03T19:51:46 < PaulFertser> Both from a "private browsing" firefox tab.
2019-03-03T19:51:58 < antto> as if it cares ;P~
2019-03-03T19:53:08 < PaulFertser> "net.ipv6.conf.wlp6s2.use_tempaddr = 2" , that means my laptop is switching addresses all the time ("Privacy Extensions")
2019-03-03T19:54:37 < jpa-> i would have searched for   avr-iot wg schematic   which gives first result in google but doesn't find it in ddg
2019-03-03T19:55:13 < antto> i don't even wanna know wtf that is just cuz i see "iot" in it
2019-03-03T19:55:23 < BrainDamage> PaulFertser: that's not what they rely on
2019-03-03T19:55:38 < antto> PaulFertser they know it's still you
2019-03-03T19:55:43 < antto> ..by other data
2019-03-03T19:56:09 < PaulFertser> jpa-: no, it's the same first result in DDG too here.
2019-03-03T19:56:10 < BrainDamage> canvas fingerprinting, ssl fingerprinting, etc etc
2019-03-03T19:56:15 < PaulFertser> (for schematics)
2019-03-03T19:57:02 < BrainDamage> first hit in DDG here too
2019-03-03T19:57:17 < jpa-> PaulFertser: hmm actually yeah, it's just a different pdf that what google finds
2019-03-03T19:57:23 < jpa-> but same info
2019-03-03T19:57:27 < PaulFertser> BrainDamage: I know they _can_ do that but is there any data to actually support the claim? I think it's usually pretty easy to showcase "targetting" when not using a private tab, but has anyone reproduced similar results with it?
2019-03-03T19:57:52 < BrainDamage> not in the searches, but I know for a fact they use those
2019-03-03T19:58:15 < BrainDamage> try to login in gmail scrambling some of those, and it'll complain that you've login from a different browser
2019-03-03T19:58:33 < BrainDamage> canvas fingerprinting for sure it's used for example
2019-03-03T19:59:06 < PaulFertser> BrainDamage: yes, but I am not sure they actually use it for requests that are not related to logging in and not providing authentication cookies.
2019-03-03T19:59:30 < BrainDamage> I'll just assume the worst because it's the safest option
2019-03-03T20:00:00 < Steffanx> what result are we talking about PaulFertser? avr-iot.com?
2019-03-03T20:00:18 < antto> not gon click
2019-03-03T20:00:24 < PaulFertser> Steffanx: no, http://ww1.microchip.com/downloads/en/DeviceDoc/AVR-IoT_WG_Schematics.pdf
2019-03-03T20:00:39  * antto sprinkles holy water in Steffanx's face
2019-03-03T20:01:35 < Steffanx> but to be honest. You're looking for schematics. "avr-iot wg schematics"  is what i would've used.
2019-03-03T20:01:41 < Steffanx> => first hit
2019-03-03T20:01:53 < PaulFertser> BrainDamage: also, canvas fingerprinting, I do not think web-browser gives any dimensions in the GET requests parameters, so how is that supposed to work?

2019-03-03T20:02:52 < PaulFertser> Steffanx: well, yes, but in this case I was thinking about getting to the official device description page first as I wasn't sure about the exact board name etc. But what I really needed were the schematics.

2019-03-03T20:04:24 < Steffanx> lol antto.  :)
2019-03-03T20:04:26 < bitmask> you can have it
2019-03-03T20:05:41 < BrainDamage> PaulFertser: the fingerprinting is not the browser size, they ask the browser to render a piece of text, then hash it, and send back the hash
2019-03-03T20:05:55 < PaulFertser> BrainDamage: that doesn't seem to be possible with plain HTTP, no.
2019-03-03T20:06:02 < BrainDamage> it's not
2019-03-03T20:06:35 < PaulFertser> And I'm not running google's scripts in my web-browser usually.

2019-03-03T20:35:13 < aandrew> wow. 2019 and ubuntu still has goofy fucking install issues related to the date
2019-03-03T20:35:17 < aandrew> "libc6-udeb" could not be installed, installer just explodes
2019-03-03T20:35:22 < aandrew> there's a new mini.iso published on the 21st of Feb 2019 that hopefully fixes it
2019-03-03T20:35:24 < aandrew> what a shitshow
2019-03-03T20:35:27 < aandrew> truly the year of linux on the desktop
2019-03-03T20:35:46 < Getty> again? ;)
2019-03-03T20:36:10 < BrainDamage> every year is the year of the linux desktop
2019-03-03T20:36:43 < Getty> \o/
2019-03-03T20:37:17 < aandrew> and it still asks for swap. in 2019. 
2019-03-03T20:37:23 < aandrew> fuck off with swap partitions
2019-03-03T20:37:39 < aandrew> create a swapfile like any sane system in the last 15 years
2019-03-03T20:41:13 < jpa-> > uses linux > annoyed to be offered choices
2019-03-03T20:41:51 < aandrew> jpa-: not quite
2019-03-03T20:42:05 < aandrew> it's actually lack of being offered the choice
2019-03-03T20:42:21 < PaulFertser> aandrew: suspend-to-disk is kinda problematic with swap file.
2019-03-03T20:42:29 < aandrew> I can't create a swapfile with the installer, it whines about there not being a swap partition instad of saying "wow it's 2019, want a swapfile since you didn't define a swap partition?"
2019-03-03T20:42:41 < PaulFertser> aandrew: and also it's unclear why you want swap access to go through the filesystem layer.
2019-03-03T20:42:54 < aandrew> PaulFertser: it's virtual so no suspend :-)
2019-03-03T20:43:19 < aandrew> PaulFertser: becuase it is such a minimal layer it's not worth the bother of having a dedicated swap partition that is a pain in the dick to resize should you ever want to
2019-03-03T20:43:38 < PaulFertser> aandrew: then do not define swap at all, duh. If you need some, you'll add it later trivially.
2019-03-03T20:43:47 < aandrew> yes
2019-03-03T20:44:11 < aandrew> but then the installer shouldn't be clutching its pearls about the lack of partition. 
2019-03-03T20:44:20 < aandrew> really I'm just bitching about trivial things, I know
2019-03-03T20:46:32 < aandrew> there we go, 16.04 installed. I am not sure what the issue is but if there is no 3d acceleration turned on the gui installer also explodes but CLI works fine
2019-03-03T20:46:42 < aandrew> they must have gotten fancy(ier) with teh installer since I used it last
2019-03-03T20:46:48 < PaulFertser> aandrew: man, you're installing Ubuntu, it's a broken version of Debian, you're not in position to complain about UI ;) 
2019-03-03T20:47:30 < aandrew> yeah I am replacing a debian vm. I prefer debian tbh but I've found that debian's gotten worse over the years and ubuntu's kind of taken over as a better debian than debian
2019-03-03T20:48:05 < aandrew> so now instead of vdeb.local it's vubuntu.local :-)
2019-03-03T20:48:16 < PaulFertser> aandrew: in what regard is ubuntu better than debian for you?

2019-03-03T21:01:42 < KolK> hello, dwo days ago I asked for help with connecting to stm32 (f446re) bootloader
2019-03-03T21:02:00 < KolK> my stm32 replies with 0xff to 0x7f 
2019-03-03T21:02:15 < KolK> and initially I thought that it may be a problem of pl2303
2019-03-03T21:02:50 < KolK> now I'm using cp2102
2019-03-03T21:02:56 < KolK> and I receive the same answers
2019-03-03T21:03:30 < KolK> the only difference is that cp2102 not connected to anything doesn't respond with rubbish
2019-03-03T21:03:39 < KolK> pl2303 does
2019-03-03T21:04:01 < KolK> Do you know what may is a problem?
2019-03-03T21:06:30 < KolK> I'm using USART3 with baudrate 9600, one stopbit and even parity
2019-03-03T21:27:27 < KolK> depending on baudrate, I receive different results
2019-03-03T21:33:22 < aandrew> PaulFertser: it's little things actually .. a lot of packages are in the main ubuntu repos but you play goofy games with sid on debian. ubuntu polished some of the user shit better than debian did and nobody seems interested to do so on debian
2019-03-03T21:33:43 < aandrew> it's hard to put my finger on it unless I'm in the middle of trying to figure something out that is directly causing pain at the time
2019-03-03T21:37:15 < aandrew> and no it's not hte wallpaper. lol

2019-03-03T22:20:54 < qyx> debian installer allows no swap, it just asks if you are sure
2019-03-03T22:20:57 < qyx> ah ubuntu
2019-03-03T22:20:59 < qyx> fuk ubuntu
2019-03-03T22:21:15 < qyx> also, swap on lvm is like 2 clicks
2019-03-03T22:22:00 < qyx> and resize is faster than dongs is able to find the altium icon on its desktop
2019-03-03T22:22:54 < zyp> the fuck you need swap for
2019-03-03T22:23:25 < qyx> idk I don't use swap

2019-03-03T23:59:10 < qyx> if you short rx/tx of the converter (excluding the nucleo from the circuit), can you see the echo on your console?
2019-03-03T23:59:54 < qyx> also, with your current setup, can you measure the idle voltage on rx/tx pins?

2019-03-04T05:05:27 < R2COM> (both are low of course, since i got old GTX980)
2019-03-04T05:05:53 < R2COM> but im curious... it seems that my processor didnt give a shit about setting to 4.2GHz and temp risen only 15C up... so... maybe i can push even more?
2019-03-04T05:06:03 < R2COM> hmm
2019-03-04T05:13:45 < Cracki> if you do that, you might have to raise voltage too
2019-03-04T05:14:20 < Cracki> 35C idle I take it
2019-03-04T05:14:55 < Cracki> when it hits its temp limit, it'll throttle on its own...

2019-03-04T09:50:32 < Cracki> what do you usually have? solid nitrogen boulders?
2019-03-04T09:51:25 < jadew> also snow
2019-03-04T09:51:32 < jadew> it's not that uncommon in march

2019-03-04T13:21:50 < invzim> .1mm/.2mm it looked like
2019-03-04T13:21:54 < englishman> i ask because i've seen a bunch of pro projects now that just put a stupidly small drillsize, and get the fab to bump it up to whatever
2019-03-04T13:22:17 < invzim> they had mostly 'normal' 0.2mm drill vias

2019-03-04T13:34:13 < jpa-> even though you could probably fan out that STM32 4-row 0.5mm bga layout with just jlcpcb specs (4mil trace/space, 0.5mm diameter via)
2019-03-04T13:34:43 < karlp> mp157 is just such a weak cortex-a though..
2019-03-04T13:34:48 < karlp> that module is a nic esize though.
2019-03-04T13:34:51 < karlp> what are they charging for that?
2019-03-04T13:35:21 < zyp> jpa-, hmm
2019-03-04T13:36:07 < zyp> 0.5mm pitch is 0.7mm diagonal, 0.5mm diameter vias in between leaves 0.2mm, enough for 0.1mm diameter pads and 0.1mm diameter spacing

2019-03-04T13:37:30 < jpa-> zyp: i was thinking more like 0.2mm pads, enough space to get one trace in between -> bring out traces to both sides from the 4 edge rows and stagger vias there

2019-03-04T13:38:12 < jpa-> would be really annoying though, and the outer via rows would block inner layer routing quite effectively
2019-03-04T13:38:47 < jpa-> (hm, if you need outer via rows, of course you could just bring out the traces directly from the outer two rows)
2019-03-04T13:41:02 < zyp> at a 0.7mm diagonal, you can't fit 0.5mm vias and 0.2mm pads with any clearance in between
2019-03-04T13:41:44 < invzim> zyp: that's a cool little board

2019-03-04T14:35:15 < zyp> there's one reason - people wanna have something readymade to show that it works
2019-03-04T14:35:47 < zyp> you can't ship something like that without any sort of example code
2019-03-04T14:36:05 < emeryth> it's for the windoze devs

2019-03-04T15:01:51 < justMaku> i'm trying to do i2c slave (with a master on nrf52) and i simply can't get it to work
2019-03-04T15:02:09 < justMaku> according to logic analyzer, nrf52 is doing a setup for a write
2019-03-04T15:02:21 < justMaku> but this data never reaches stm32
2019-03-04T15:02:42 < justMaku> i've used different pullup resistors (3,6k and 6,1k) with no change
2019-03-04T15:02:51 < justMaku> anything that i could be missing?
2019-03-04T15:03:09 < justMaku> HAL_I2C_Slave_Receive returns HAL_TIMEOUT

2019-03-04T17:21:18 < aandrew> flash probe 0 finds 1mb for the f756 but then program foo.hex fails
2019-03-04T17:24:10 < justMaku> ugh
2019-03-04T17:24:25 < justMaku> i did some more testing and turned the stm part of the board into master
2019-03-04T17:24:35 < justMaku> i can't get any signal on the SDA/SCL lines at all
2019-03-04T17:24:56 < justMaku> i assume you can do i2c write attempt without any devices on the bus and it should show on the scope
2019-03-04T17:25:05 < justMaku> but for me both lines stay low for the whole time.
2019-03-04T17:25:12 < aandrew> justMaku: post your code

2019-03-04T17:34:05 < aandrew> https://pastebin.com/G3adHvEg is my i2c init code. it absolutely works
2019-03-04T17:35:06 < aandrew> you need a static I2C_HandleTypeDef hi2c3;
2019-03-04T17:35:08 < aandrew> of course
2019-03-04T17:35:10 < aandrew> didn't paste that 
2019-03-04T17:35:47 < aandrew> I really don't think you need the analog/digital filter shit but that's just what was pasted
2019-03-04T17:36:17 < justMaku> aandrew: the analog/digital filters i got from cube mx
2019-03-04T17:37:00 < justMaku> how did you calculat that value for hi2c3.Init.Timing? 
2019-03-04T17:37:08 < aandrew> justMaku: same here, that's what cubemx did
2019-03-04T17:37:20 < aandrew> justMaku: I told cubemx 100khz and then divided it by 4 for 400khz
2019-03-04T17:37:32 < aandrew> I couldn't be arsed to screw around with calculating it myself
2019-03-04T17:38:26 < justMaku> well, then i'm out of ideas
2019-03-04T17:38:48 < aandrew> do you have 2k pullups?
2019-03-04T17:39:02 < justMaku> hmmm, let me check the *magic drawer*
2019-03-04T17:39:09 < justMaku> i used 3,5k and 6,1k so far
2019-03-04T17:39:21 < aandrew> 3k5 is plenty
2019-03-04T17:39:23 < aandrew> weird, but plenty
2019-03-04T17:41:19 < aandrew> maybe make sure your gpio clocks are enabled as well, maybe they need to be enabled for the gpio to function even though the alternate function is controlling the line
2019-03-04T17:41:43 < aandrew> I enable ALL the GPIO port clocks in another function which is why it's not in the MSP init
2019-03-04T17:42:09 < aandrew> and my MSP is enabling the STM32 pullups on the GPIo but I don't think they're enough, I use physical resistors
2019-03-04T17:43:16 < justMaku> i do __HAL_RCC_GPIOB_CLK_ENABLE before setting up the gpio
2019-03-04T17:44:43 < justMaku> and also SYSCFG_CLK and PWR_CLK
2019-03-04T17:45:18 < qyx> aandrew: because you have lvm by default of course

2019-03-04T18:11:25 < aandrew> zyp: as much as possible
2019-03-04T18:11:34 < mawk> 8 gib
2019-03-04T18:11:39 < zyp> haha, ok
2019-03-04T18:11:48 < mawk> on a desktop
2019-03-04T18:11:52 < aandrew> zyp: not joking
2019-03-04T18:11:59 < zyp> mawk, and a laptop?

2019-03-04T18:12:02 < aandrew> fast ram isn't as important as lots of it
2019-03-04T18:12:08 < mawk> yeah by desktop I mean not server, so for a laptop too

2019-03-04T18:12:21 < zyp> aandrew, that was to mawk, I totally agree with you
2019-03-04T18:12:21 < aandrew> when I bought that 1st gen i7 I bought as much RAM as it oculd hold (24GB)
2019-03-04T18:12:28 < zyp> same
2019-03-04T18:12:35 < zyp> 32G in my case
2019-03-04T18:12:37 < aandrew> when I bought this macbook air I bought the i7 and 8GB which was as much as it could hold
2019-03-04T18:12:45 < mawk> 32G is what I have in the server
2019-03-04T18:13:00 < aandrew> my blade server only has 48G on esxi but that's becuase I only had 4G sticks and registered ecc DDR2 is expensive
2019-03-04T18:13:09 < zyp> I've got 32G on both the desktop and the server
2019-03-04T18:13:18 < jpa-> i wouldn't buy a new system for desktop with less than 32GB nowadays
2019-03-04T18:13:25 < jpa-> in home server i can be ok with 4GB
2019-03-04T18:13:26 < aandrew> 100% agreed
2019-03-04T18:13:44 < fenugrec> is it possible to pay less than ~ 10$/GB for desktop ddr4 ?
2019-03-04T18:13:46 < zyp> servers don't really use that much, mostly disk cache
2019-03-04T18:13:49 < fenugrec> seems to be the starting price
2019-03-04T18:14:05 < BrainDamage> I have 24GB in my laptop
2019-03-04T18:14:50 < mawk> I have 12 GiB in this laptop, but I discovered it only some time ago
2019-03-04T18:14:54 < mawk> I thought it had 4 GiB
2019-03-04T18:14:54 < BrainDamage> one huge advantage of having no swap is that OOM kicks in faster
2019-03-04T18:15:01 < mawk> one and only

2019-03-04T18:15:15 < mawk> but it's still a workaround, the true fix is to get more ram
2019-03-04T18:15:37 < BrainDamage> linux swap code performance is just awful
2019-03-04T18:15:37 < jpa-> cheapest 32GB kits are ~200 EUR here
2019-03-04T18:15:42 < BrainDamage> try to swapoff and measure IO
2019-03-04T18:15:54 < BrainDamage> you'll find that you're not IO limited
2019-03-04T18:16:14 < zyp> jpa-, sounds like ram prices have been fairly fixed for the last year then
2019-03-04T18:16:22 < BrainDamage> on my 800MB/s writethrough SSD I had 2MB/s read speed
2019-03-04T18:16:29 < jpa-> BrainDamage: yeah, and it is even worse if you are not swapping in everything in one go but application fetches individual pages here and there
2019-03-04T18:16:34 < zyp> IIRC I paid around 2k NOK for each 32G set that I bought in respectively 2012 and 2013
2019-03-04T18:16:41 < zyp> last years*
2019-03-04T18:17:26 < zyp> also, my home server is apparently using a lot more ram than I expected

2019-03-04T18:23:55 < mawk> but IBM built something that has effectively 256 TiB
2019-03-04T18:24:36 < justMaku> aandrew: I'm correct in my thinking that I should see something on the scope on the i2c bus even if theres no peripheral connected?
2019-03-04T18:24:58 < zyp> you're doing a master?
2019-03-04T18:25:25 < zyp> if you're scoping a master trying to talk to a disconnected slave, you should see a start condition, master sending the address and not getting an ACK back
2019-03-04T18:25:37 < aandrew> justMaku: yes, you should see the initial 9 bit clock tick with the first 8 bits correct and a '1' for the 9th bit since nothing is ACKing
2019-03-04T18:28:46 < justMaku> ugh, then something is terribly wrong. I even did a completely clean project with cubemx that only does i2c master with write in the main loop and still nothing visible on the scope
2019-03-04T18:28:54 < justMaku> well, i guess that's the problem for tomorrow

2019-03-04T18:31:28 < dongs> that usually means no peripheral clock, wrong AF, etc

2019-03-04T18:32:49 < justMaku> i assume the cubemx generated project would set that for me
2019-03-04T18:33:55 < justMaku> but at this point i will also take "well, the radiation from the sun flipped some bits in the memory during the compilation, who knows" as an explanation

2019-03-05T01:48:53 < aandrew> weird
2019-03-05T01:48:58 < aandrew> I can retarget putch but not getchar
2019-03-05T01:49:52 < karlp> retarget getchar_ or something?
2019-03-05T01:49:59 < karlp> or _read or something?
2019-03-05T01:50:21  * karlp hasn't usd putch(ar) getch(ar) shit for fucking ever, never remember
2019-03-05T01:52:44 < karlp> aandrew: are you using one of those new value line tiny flash f7s?
2019-03-05T01:54:20 < karlp> you probably need this http://openocd.zylin.com/#/c/4926/ if you haven't gotten it fixed already
2019-03-05T02:01:31 < aandrew> karlp: not using one of those no
2019-03-05T02:02:04 < aandrew> output retargeting is perfect
2019-03-05T02:02:15 < aandrew> I haven't found the right incantation for input though
2019-03-05T02:02:32 < aandrew> getchar is present but is buried in some lib I haven't got access too, and isn't _weak() apparently
2019-03-05T02:02:43 < aandrew> I'm not getting compile or link errors, but it's also not getting to *my* getchar()
2019-03-05T02:02:57 < aandrew> tried fgetc as well
2019-03-05T02:03:02 < aandrew> and _read
2019-03-05T02:03:31 < karlp> pro software right?
2019-03-05T02:03:38 < aandrew> yep
2019-03-05T02:03:40 < aandrew> the pro-est
2019-03-05T02:03:43 < karlp> call your vendors 24/7 suport line?
2019-03-05T02:07:25 < karlp> armcc now free, no size limits, thanks mbed.
2019-03-05T02:07:42 < karlp> I wonder how much they chopped it up though
2019-03-05T02:08:41 < englishman> no size limits so you can use gigantic newlib-nano
2019-03-05T02:10:53 < karlp> "Compilation is restricted to Mbed OS only."
2019-03-05T02:13:29 < karlp> heh, still not supporting linux. dspite being a vscode based thing, with mac and windows support
2019-03-05T02:14:04 < karlp> "There was also strong feedback from some of you around the choice of Eclipse, so we kept that in mind.
2019-03-05T02:14:06 < karlp> "
2019-03-05T02:15:11 < karlp> ok, no, it's not vscode, it's theia, which is also based on monaco like vscode.
2019-03-05T02:15:22 < karlp> and.... is from eclipse :)

2019-03-05T05:57:55 < R2COM> so after overclocking my CPU i gamed and ran some tests and bench'ed it with sopme soft all looks stable and below 60C
2019-03-05T05:58:06 < rajkosto> what cpu
2019-03-05T05:58:08 < rajkosto> and to what
2019-03-05T05:58:10 < R2COM> and bench results for that processor seem good compared to other submissions
2019-03-05T05:58:16 < R2COM> i7-5930k
2019-03-05T05:58:23 < rajkosto> why ask here 
2019-03-05T05:58:26 < R2COM> its 3.5GHz i OC'ed it to 4.2GHz
2019-03-05T05:59:16 < R2COM> ask what
2019-03-05T05:59:52 -!- machinehum [~machinehu@ip-142-232-167-15.ptr.bcit.ca] has joined ##stm32
2019-03-05T05:59:59 < rajkosto> i overclocked a 3570k from stock 3.whatever to 4.7GHz @ 1.3V or 4.9GHz @ 1.37V
2019-03-05T06:00:19 < rajkosto> the other one couldnt reach even 4.2GHz
2019-03-05T06:01:03 < rajkosto> either way dont do it unless you can guarantee stability (run p95 AVX for like hours while never overheating) or you will always be wondering if you are crashing due to bad software or hardware
2019-03-05T06:02:42 < R2COM> 4.7GHz for that processor seems to be stretch no?
2019-03-05T06:02:51 < rajkosto> yes i had a really good one and a pretty bad one
2019-03-05T06:03:06 < rajkosto> different batches
2019-03-05T06:03:13 < rajkosto> anyway, overclock your stm32
2019-03-05T06:03:15 < rajkosto> then ask here
2019-03-05T06:03:51 < R2COM> i can ask here anything
2019-03-05T06:07:02 < Cracki> so... I remember talk of the CM7-based ones crapping out in some way at max specified frequency already
2019-03-05T06:07:14 < rajkosto> i only have f103 and f4xx
2019-03-05T06:07:19 < Cracki> who overclocked their stm32 (which) and got what results?
2019-03-05T06:07:21 < rajkosto> both can run at like 150% of rated freq
2019-03-05T06:07:23 < rajkosto> no issues
2019-03-05T06:07:25 < Cracki> hmmmm
2019-03-05T06:07:28 < rajkosto> f103 cant usb at 128MHz tho
2019-03-05T06:07:35 < rajkosto> as theres no divider availalbe to get it back to 48 
2019-03-05T06:07:37 < Cracki> heh
2019-03-05T06:07:47 < rajkosto> gd32 actually fixed that by adding 1.5 and 2.5 dividers
2019-03-05T06:07:55 < Cracki> what should they run at, 72 mhz usually?
2019-03-05T06:08:00 < rajkosto> yes
2019-03-05T06:08:08 < Cracki> 96 would make 48 mhz well
2019-03-05T06:08:21 < rajkosto> NOT ENOUGH
2019-03-05T06:08:55 < Cracki> 1.5 * 72 is only 108
2019-03-05T06:08:55 < rajkosto> i wanted to maximize the display's SPI which is 66MHz max, 128 gets me 64 which is close
2019-03-05T06:09:03 < Cracki> so you're saying 128 mhz on an f103 still works?
2019-03-05T06:09:11 < rajkosto> yes if you dont want usb
2019-03-05T06:09:17 < Cracki> that's very nice to know
2019-03-05T06:10:11 < rajkosto> the f4xx can run at like 400+ mhz i forgot
2019-03-05T06:10:13 < machinehum> Probably not forever
2019-03-05T06:10:23 < rajkosto> nah, forever, just uses more milliamps
2019-03-05T06:10:50 < machinehum> 400+mhz wtf...
2019-03-05T06:11:04 < machinehum> If can run indefinatly

2019-03-05T06:11:35 < rajkosto> stm32f407vg
2019-03-05T06:11:42 < Cracki> those can do 400? hmmmm
2019-03-05T06:12:10 < Cracki> overclocked or in spec?
2019-03-05T06:12:15 < rajkosto> overclocked ofc
2019-03-05T06:12:17 < rajkosto> normal is 2xx
2019-03-05T06:12:18 < Cracki> :>
2019-03-05T06:12:22 < Cracki> 216 or something yeh
2019-03-05T06:13:30 < Cracki> selecting 216-400 mhz on mouser, the f730 seems cheapest
2019-03-05T06:14:03 < rajkosto> why do you need that many mhz
2019-03-05T06:14:13 < rajkosto> at that point just use an A7 or A53 soc
2019-03-05T06:14:42 < Cracki> :P
2019-03-05T06:15:19 < Cracki> I'm just glad to hear the f1 and f4 are a little elastic
2019-03-05T06:15:54 < Cracki> huh, mouser offers 180 mhz max for f4 series
2019-03-05T06:16:26 < rajkosto> yes its 186 default
2019-03-05T06:16:52 < Cracki> 168 for many
2019-03-05T06:17:36 < R2COM> its not that easy, there might be long term reliability issues with 2x freq
2019-03-05T06:17:52 < rajkosto> probably, dont do ti
2019-03-05T06:18:00 < Cracki> yolo
2019-03-05T06:18:13 < rajkosto> but i had to do it on f103 to get dat sweet 15ms screen draw/send time

2019-03-05T06:20:39 < R2COM> what im saying is, its ok to do it for some custom/own projects, noone would do it for product in qty. being sold
2019-03-05T06:20:48 < Cracki> sure, stay in your slums, get eaten by angry earth gods
2019-03-05T06:21:03 < Cracki> obviously nobody's thinking of overclocking for production :>

2019-03-05T06:21:51 < R2COM> ok
2019-03-05T06:22:25 < Cracki> if the customer wants MOAR FEATURES and signs off on the measure... ¯\_(ツ)_/¯
2019-03-05T06:25:50 < machinehum> Possible to get the MP1 yet?

2019-03-05T06:50:40 < Cracki> I looked into optical encoders recently... the new shit is reflective thingies, super flat chips (instead of plastic forks to thread your timing strip/disc through) and very high tech.
2019-03-05T06:50:45 < Cracki> and they cost an arm and a leg
2019-03-05T06:51:20 < machinehum> Any reason to not use the magnetic ones?
2019-03-05T06:51:22 < Cracki> wouldn't be surprised if ST introduced their new shit priced according to demand
2019-03-05T06:51:28 < Cracki> magnetic? fuck off with that
2019-03-05T06:51:29 < machinehum> lol
2019-03-05T06:51:33 < Cracki> I want resolution
2019-03-05T06:51:40 < Cracki> and simplicity
2019-03-05T06:51:55 < machinehum> What res?
2019-03-05T06:52:01 < Cracki> the usual magnetic encoders look at multi-pole magnets (on motor shaft) that have maybe 11 poles
2019-03-05T06:52:07 < machinehum> Nah
2019-03-05T06:52:15 < machinehum> There are some that will give you 4096
2019-03-05T06:52:19 < machinehum> I think way more actually
2019-03-05T06:52:31 < Cracki> cheap ass optical encoders can give you 100 PPR (lines/revolution)
2019-03-05T06:52:47 < Cracki> those are digitizing the magnetic field

2019-03-05T06:54:19 < Cracki> interestingly, I found breakouts of those avago thingies for 2 bucks (!) on aliex. they go for 20 bucks in the western world
2019-03-05T06:54:55 < machinehum> Yeah they "fall off" the conveyor
2019-03-05T06:54:57 < Cracki> AEDR for Avago Encoder, Reflective
2019-03-05T06:56:04 < Cracki> the last half dozen printers I took apart gave me a bunch of fork-style (transmissive) sensors but if  the chinese can use reflective ones for 2 bucks, that would be awesome

2019-03-05T06:56:35 < Cracki> very flat, SIMPLE to picknplace en masse, and solder onto a motor's ass tabs
2019-03-05T06:57:40 < machinehum> "ass tab"
2019-03-05T06:57:47 < Cracki> you can pair these fuckers with 1000 PPR code discs, so that's 4000 edges/rev already, and they can interpolate x16 on top of that
2019-03-05T06:58:02 < Cracki> back end, you know, where you have + and -
2019-03-05T06:58:09 < machinehum> Yeah got it
2019-03-05T06:58:17 < Cracki> ass is easier to type

2019-03-05T06:58:28 < machinehum> Which moters are you using? Just the cheap lil brushed ones
2019-03-05T06:58:41 < Cracki> besides, roosh has been ranting about police women in tight pants again. he seems to not like the butt
2019-03-05T06:58:47 < Cracki> aye cheap lil brushed ones
2019-03-05T06:59:10 < Cracki> not too small tho.... boss gave me a mabuchi with 100 PPR optical encoder. motor diameter is ~30 mm
2019-03-05T06:59:23 < Cracki> RS445pw15200R
2019-03-05T06:59:40 < Cracki> fully decodable type numbers, they're awesome https://www.mabuchi-motor.com/product/knowledge/classification/designations.html

2019-03-05T07:01:39 < Cracki> if you look for servos on aliexpress, you get those potentiometer thingies for RC cars, or the serious biz $$$ servos, or these geared ones with 11 PPR magnetic encoder
2019-03-05T07:02:00 < Cracki> anyway, new shit is expensive :S
2019-03-05T07:02:19 < machinehum> Those plastic geared things suck
2019-03-05T07:02:34 < machinehum> with the pot, just have an opamp and shit inside
2019-03-05T07:02:42 < Cracki> and when you ask them "212 PPI, does that mean 0.12 mm pitch?" they have no clue what you're talking about
2019-03-05T07:02:53 < machinehum> 40x shitty little plastic gears ready to rip themselves apart
2019-03-05T07:03:00 < Cracki> nah, I got a metal geared thing, but they still have slip of a few degrees
2019-03-05T07:03:16 < machinehum> Depends on the reduction I suppose
2019-03-05T07:03:21 < Cracki> I want _no_ gears so that means no shit magnetic encoder
2019-03-05T07:03:24 < machinehum> Stepper motor with encoders
2019-03-05T07:03:30 < machinehum> work nice
2019-03-05T07:03:34 < Cracki> steppers are heavy and eat current
2019-03-05T07:03:40 < machinehum> Sure do
2019-03-05T07:04:04 < machinehum> You can reduce current with a good driver
2019-03-05T07:04:04 < Cracki> besides you don't really need encoder on them if load < torque
2019-03-05T07:04:24 < machinehum> You can do fun things with the feedback
2019-03-05T07:04:56 < machinehum> With microstepping you torque goes out the window
2019-03-05T07:05:03 < Cracki> steppers have detent torque (the cogging when no current and open circuit)
2019-03-05T07:05:11 < Cracki> wrong
2019-03-05T07:05:19 < Cracki> people always misunderstand torque and microstepping
2019-03-05T07:05:28 < Cracki> it's a misunderstanding propagated by people who have no clue
2019-03-05T07:05:36 < machinehum> Damn that's me
2019-03-05T07:05:45 < Cracki> (and those who think it sounds smart)
2019-03-05T07:06:03 < Cracki> what you have is like FOC for bldcs
2019-03-05T07:06:25 < machinehum> Flux vector control
2019-03-05T07:06:33 < Cracki> field oriented
2019-03-05T07:06:41 < Cracki> and what you have is the magnetic fields giving you one vector, and the rotor giving you another
2019-03-05T07:06:48 < machinehum> Yeah that shit is cool
2019-03-05T07:06:49 < Cracki> and the field pulls the rotor
2019-03-05T07:07:02 < Cracki> and the misunderstanding is this:
2019-03-05T07:07:18 < Cracki> torque is proportional to the angle between magnetic field and rotor
2019-03-05T07:07:22 < Cracki> regardless of microstepping
2019-03-05T07:07:37 < Cracki> the misunderstanding comes from the fact that one microstep is a small angle
2019-03-05T07:07:48 < Cracki> so they think you get less torque, but that's just bullshit
2019-03-05T07:08:29 < Cracki> *proportional to the *cosine* of that difference, I think
2019-03-05T07:08:34 < machinehum> Good to know
2019-03-05T07:08:37 < Cracki> or 1-cos
2019-03-05T07:08:49 < Cracki> watever, stuff on a unit circle
2019-03-05T07:09:05 < Cracki> hm no, sine is probably right
2019-03-05T07:09:57 < machinehum> Is the holding torque reduced?
2019-03-05T07:10:18 < Cracki> microstepping has no effect on that
2019-03-05T07:10:24 < Cracki> there's one caveat tho
2019-03-05T07:10:40 < Cracki> with full stepping, you give 100% on both coils and you drive them into the diagonal of each quadrant
2019-03-05T07:10:49 < Cracki> so the vector is 141%, let's say
2019-03-05T07:11:13 < Cracki> if you move in the unit circle, you move at 100%, so when it points into one corner, you get 71% per coil
2019-03-05T07:11:20 < Cracki> but you already have that with half-stepping
2019-03-05T07:12:02 < machinehum> hmm
2019-03-05T07:12:03 < Cracki> one *could* do half-stepping with +100+0, +100+100, 0+100, -100+100,... but then you'd have uneven field strength, so uneven torque, so that's bad
2019-03-05T07:12:49 < machinehum> cool

2019-03-05T10:33:10 < dongs> 'connector'?
2019-03-05T10:33:21 < dongs> you just put some pads spaced 2.54mm and done?
2019-03-05T10:35:29 < Ecco> oh, yeah, I meant the other side :)
2019-03-05T10:35:33 < Ecco> The pogo pins themselves :)
2019-03-05T10:36:27 < qyx> can you show a google image of them?
2019-03-05T10:36:35 < Ecco> wat? of pogo pins?
2019-03-05T10:36:46 < Ecco> https://5.imimg.com/data5/KH/OM/MY-9444210/pogo-pins-connector-500x500.jpg
2019-03-05T10:37:41 < qyx> so you want the connector assembly like the tagconnect?
2019-03-05T10:37:45 < qyx> or what
2019-03-05T10:37:52 < qyx> we used ingun pins or feinmetall
2019-03-05T10:38:00 < qyx> but all connectors were custom made
2019-03-05T10:38:04 < dongs> Choose PCBA manufacturer which can produce PCB of IPC CLASS 3 quality, 5/5 mil trace resolution and 0.2 mm holes. Avoid manufacturer who claims "quality" and "satisfaction" but doesn't really know what will be IPC CLASS rating for this project.
2019-03-05T10:38:08 < dongs> lol
2019-03-05T10:38:23 < Ecco> feinmetall -> interesting
2019-03-05T10:38:53 < dongs> Ecco: https://www.mill-max.com/product_finder/1/84 but expensive as Fuck
2019-03-05T10:40:11 < tjq> Haohmaru: anime
2019-03-05T10:40:14 < qyx> there were some PTR or how were they called
2019-03-05T10:40:18 < qyx> they were a bit cheaper
2019-03-05T10:40:19 < dongs> i think i sampled their 2x4 or 2x5 or so array of pogos
2019-03-05T10:40:26 < dongs> for touch-flashing of stuff
2019-03-05T10:40:41 < Ecco> I've browsed the mill-max catalogue
2019-03-05T10:40:47 < Ecco> and they don't seem to have the kind of part I'm after
2019-03-05T10:40:53 < dongs> well fuck you then
2019-03-05T10:40:55 < dongs> autism away

2019-03-05T10:41:20 < dongs> yeah these are pogo pins.
2019-03-05T10:41:23 < Ecco> The mill-max have a very short travel
2019-03-05T10:41:25 < dongs> they're like $3 for 100 in china
2019-03-05T10:41:33 < dongs> you didnt fucking specify how long you wanted your shit
2019-03-05T10:42:01 < Ecco> That's true
2019-03-05T10:42:32 < qyx> also as I said https://ingun.com/en
2019-03-05T10:42:40 < qyx> but $$$
2019-03-05T10:42:42 < dongs> on aliexpress they're called P75 pogo pins
2019-03-05T10:42:46 < Ecco> ok!
2019-03-05T10:43:09 < qyx> I should po-go something too
2019-03-05T10:43:24 < Ecco> Indeed
2019-03-05T10:43:35 < dongs> i always pogo stuff.
2019-03-05T10:43:41 < dongs> but i just make a PCB to mount the pogos in
2019-03-05T10:43:47 < Ecco> I'm a bit cautious about the quality of the chinese ones
2019-03-05T10:43:48 < qyx> lol 100pcs for $1.37
2019-03-05T10:43:49 < dongs> then add some standoffs into mounting holes and shit
2019-03-05T10:43:52 < dongs> qyx, yep
2019-03-05T10:43:54 < Ecco> so I was looking for "reputable" manufacturers
2019-03-05T10:43:57 < dongs> chinagirl sells them for around that much
2019-03-05T10:43:57 < qyx> ololol
2019-03-05T10:43:59 < dongs> and they work great
2019-03-05T10:43:59 < Ecco> since I'd just buy a few of them anyway
2019-03-05T10:44:00 < dongs> zero issues
2019-03-05T10:44:07 < qyx> we were buying such things for ~10€/1pc
2019-03-05T10:44:14 < dongs> ayee. 
2019-03-05T10:44:18 < dongs> digikey prices for them are fucking rape
2019-03-05T10:44:32 < dongs> the best ones are diamond head
2019-03-05T10:44:35 < dongs> i forgot waht lm75 number that is
2019-03-05T10:44:56 < qyx> it depends, we used different heads for different purposes
2019-03-05T10:44:59 < Ecco> diamond head = multiple smaller "peaks" at the top?
2019-03-05T10:44:59 < dongs> ah tere it is P75-LM2
2019-03-05T10:45:00 < qyx> usually not for PCB
2019-03-05T10:45:13 < Ecco> oh, ok, got it
2019-03-05T10:46:20 < qyx> mhm I should order some just for the lulz
2019-03-05T10:46:28 < dongs> lcsc should haev some as well
2019-03-05T10:46:30 < dongs> under same part#

2019-03-05T15:26:32 < rmaw> dongs, std::get is for getting the an element of a tuple
2019-03-05T15:26:36 < rmaw> its not m[1]
2019-03-05T15:27:04 < rmaw> a tuple is heterogeneous type
2019-03-05T15:27:22 < dongs> you lost me at "tuple"
2019-03-05T15:27:34 < rmaw> std::tuple<int,double,std::string>
2019-03-05T15:28:30 < dongs> did C++ 2019 or whateer somehow fix bitfields casting to work on all platforms?
2019-03-05T15:29:07 < dongs> this nigger is doing struct crap { uint16_t aids: 12; uint16_t seq : 4; } and then doing crap *foo = (crap *)data
2019-03-05T15:31:27 < mawk> if it's a tuple yes rmaw 
2019-03-05T15:31:28 < rmaw> also dongs, "the whole purpose of C-based shit is to fucking have types" , with auto it still absolutely has a type, the type is just deduced
2019-03-05T15:31:33 < mawk> but std::get works for other stuff like arrays
2019-03-05T15:32:05 < dongs> uhh bro, i don't wanna "guess" what hte type is
2019-03-05T15:32:07 < mawk> no I think it's still pretty undefined that dongs 
2019-03-05T15:32:09 < dongs> i want to see the shit in code
2019-03-05T15:32:19 < rmaw> dongs, its mainly when you have a mass of templated stuff its useful
2019-03-05T15:32:23 < dongs> if the faggot writing is too lazy to know what type hes getting out of that shit
2019-03-05T15:32:26 < mawk> have a pro IDE tool that shows the type
2019-03-05T15:32:28 < dongs> he should problty just switch tyo rtuby or somethign
2019-03-05T15:32:32 < rmaw> or your writing generic code
2019-03-05T15:33:02 < mawk> "auto" is nicer than "std::enable_if_t<std::is_numeric_v<T>, T, uintmax_t>"
2019-03-05T15:33:05 < rmaw> you can still write the type if you want
2019-03-05T15:40:45 < rajkosto> > 2019
2019-03-05T15:40:55 < rajkosto> > not having clang or msvc tell you what the type is when you hover over variable
2019-03-05T15:41:03 < dongs> it does
2019-03-05T15:41:06 < dongs> thats not the point
2019-03-05T15:41:13 < rajkosto> you should still use the type unless it leads to putting the type twice into one line
2019-03-05T15:41:21 < rajkosto> or if its an unutterable/template hell type
2019-03-05T15:42:06 < jadew> dongs, auto was only introduced to solve (vector<something<something, something>>::const_iterator i = vec.begin(); ...
2019-03-05T15:42:07 < rmaw> vs 2019 is not too bad. if you go make a coffee by the time you get back the autocomplete has worked out the type
2019-03-05T15:42:15 < rmaw> and pops up
2019-03-05T15:42:33 < jadew> the fact that it's overused was sort of expected, but it's bad practice
2019-03-05T15:42:41 < mawk> you even have it in C dongs !

2019-03-05T15:46:21 < rmaw> hmm, has anyone ever bought one of the knock off ebay J-links and got it working?
2019-03-05T15:47:02 < rmaw> I bought one about 3 months ago from china, it just turned up and it appears to be junk.. everything wants to upgrade its fw then just fails
2019-03-05T15:48:15 < rajkosto> rmaw, i have gud firmware for it
2019-03-05T15:48:31 < rmaw> let me show you the one I have
2019-03-05T15:48:59 < rajkosto> mine works fantastic but it uses the stlinkv2 ugpraded to jlink firmware
2019-03-05T15:49:05 < rajkosto> so yours needs to be wired that way
2019-03-05T15:49:15 < rmaw> I thought that was only for onboard stlinks
2019-03-05T15:49:19 < rmaw> like on the devkits
2019-03-05T15:49:25 < rajkosto> potato potato
2019-03-05T15:49:27 < Ecco> how is j-link > st-link?
2019-03-05T15:49:41 < Ecco> I mean, as long as you can hook GDB, what's the difference?
2019-03-05T15:49:42 < jpa-> incremental flashing, maybe
2019-03-05T15:49:45 < rajkosto> better, not uisng openOCD, and SWO is easily accessible
2019-03-05T15:50:14 < rajkosto> but you lose VCP if you have stlinkv2.1 (and you cant get it back legitimately, the jlink -> stlink tool only flashes the non vcp firmware back)
2019-03-05T15:50:18 < rmaw> https://i.snag.gy/CpwJrP.jpg
2019-03-05T15:50:34 < rajkosto> fancy
2019-03-05T15:50:35 < rajkosto> too fancy.
2019-03-05T15:50:51 < rmaw> junk.
2019-03-05T15:51:02 < rajkosto> too many buffers
2019-03-05T15:51:12 < rajkosto> but yeah clone j-link dont work as you cant use latest firmware/software on them
2019-03-05T15:51:36 < mawk> and how do you do it non-legitimately rajkosto ?
2019-03-05T15:51:40 < mawk> get vcp back
2019-03-05T15:51:52 < rmaw> seems pointless even for the chinese to make them then
2019-03-05T15:51:58 < rmaw> which was why I was curious to buy one and try it
2019-03-05T15:51:58 < rajkosto> flash empty v2.1 bootloader back
2019-03-05T15:52:17 < rajkosto> then use hacked java upgrader to specifically flash the MSD+VCP firmware back on
2019-03-05T15:52:39 < rajkosto> (its hacked to let you choose any firmware possible)
2019-03-05T15:52:45 < mawk> ah
2019-03-05T15:52:59 < rajkosto> anyway, anything wired like MB1136 can work as a onboard stlink
2019-03-05T15:53:05 < rajkosto> and thus is upgradeable to jlink that way

2019-03-05T15:58:17 < rmaw> about $10, I bought a ULINK at the same time

2019-03-05T15:58:32 < rajkosto> whats a ulink

2019-03-05T16:02:05 < rajkosto> if you buy the stlink clone its the same layout
2019-03-05T16:02:17 < rajkosto> missing SWO, you can solder a wire for it though

2019-03-05T16:03:36 < rmaw> ohh I have a bunch of the usb ones somewhere
2019-03-05T16:03:59 < rajkosto> you can flash those to j-link
2019-03-05T16:09:16 < rmaw> is there any benefit then over stlink?
2019-03-05T16:09:35 < rmaw> I bought that jlink clone on a whim, no idea if it is a better debug solution or not
2019-03-05T16:09:46 < rajkosto> its faster and SWO is available through a separate port
2019-03-05T16:10:04 < rajkosto> so if your IDE is eclipse or has telnet console you can see it ez
2019-03-05T16:12:50 < rmaw> found one

2019-03-05T16:24:34 < BrainDamage> it's how thermal energy is distributed at varying T
2019-03-05T16:24:49 < BrainDamage> and it gives the probability of an electron to occupy a state
2019-03-05T16:25:04 < BrainDamage> for a laser, you have to pourposely implement what's called a population inversion
2019-03-05T16:25:18 < BrainDamage> where instead of the lower states, the higher states are populated
2019-03-05T16:25:35 < BrainDamage> this is represented with a negative temperature, and it'll be hotter than any positive temperature
2019-03-05T16:25:49 < BrainDamage> because it'll always transfer energy towards a positive temperature state

2019-03-05T17:33:53 < rajkosto> it should have an option to genrate interrupt on that or something

2019-03-05T21:18:40 < Laurenceb> 30MB/s loading into muh database
2019-03-05T21:25:55 < BrainDamage> no, because in order for a laser to work, the electrons has to stay in an excited state
2019-03-05T21:26:26 < BrainDamage> excited state -> population inversion -> inversed fermi dirac -> negative temperature
2019-03-05T21:27:28 < BrainDamage> in order for a laser to work, most of the electrons need to idle in the metastable state https://image.slidesharecdn.com/2xtraedit-140419000942-phpapp01/95/laser-ppt-11-638.jpg?cb=1397866226
2019-03-05T21:27:47 < BrainDamage> this is the opposite of what normally happens, where the electrons idle in the ground state
2019-03-05T21:28:50 < BrainDamage> bear in mind it's kind of useless definition
2019-03-05T21:28:57 < BrainDamage> because it works only for isolated systems
2019-03-05T21:29:46 < jadew> BrainDamage, what's an isolated system?
2019-03-05T21:29:55 < jadew> a couple of suspended atoms or something?
2019-03-05T21:30:25 < BrainDamage> an isolated system is one that doesn't exchange work with the environment
2019-03-05T21:30:37 < jadew> ah ha
2019-03-05T21:30:42 < BrainDamage> it can be as complex as you want
2019-03-05T21:30:42 < jadew> so.. kinda useless

2019-03-05T22:20:36 < kakimir> it's just about testing specification

2019-03-05T23:18:18 < Cracki> according to this, it's not supposed to have cache https://en.wikipedia.org/wiki/ARM_Cortex-M#Silicon_customization
2019-03-05T23:18:27 < Ecco> I'm pretty positive M4 never have cache
2019-03-05T23:18:35 < Cracki> maybe they pimped it
2019-03-05T23:18:47 < Ecco> They most likely confused this with an M7
2019-03-05T23:20:08 < Cracki> maybe they did something like ST did with "ART" to cache instructions
2019-03-05T23:21:09 < Cracki> better source would be nxp.com... https://www.nxp.com/products/processors-and-microcontrollers/arm-based-processors-and-mcus/i.mx-applications-processors/i.mx-8-processors/i.mx-8m-family-armcortex-a53-cortex-m4-audio-voice-video:i.MX8M
2019-03-05T23:21:42 < Cracki> block diagram says the M4 has 16+16k cache
2019-03-05T23:30:09 < zyp> CM4 doesn't come with a cache in the core itself, only CM7 does
2019-03-05T23:30:19 < Cracki> so nothing keeps them from bolting some on
2019-03-05T23:30:25 < zyp> but that doesn't stop vendors from throwing a cache in front of the CM4
2019-03-05T23:30:26 < Cracki> stm32 has ART
2019-03-05T23:30:29 < zyp> exactly
2019-03-05T23:31:47 < Ecco> oh
2019-03-05T23:32:03 < Ecco> well that's kinda different
2019-03-05T23:32:26 < Ecco> I mean specifically the data cache
2019-03-05T23:32:39 < Cracki> so they added a cache for that too, so?
2019-03-05T23:32:41 < Ecco> what's the point if the SRAM can run at clock speed?
2019-03-05T23:32:50 < Cracki> dunno, maybe it can't :>
2019-03-05T23:32:55 < zyp> also, on a hybrid platform like that, with both cortex-a and cortex-m, you'll want cache on the cortex-m if it's gonna touch any of the high latency memories anyway
2019-03-05T23:33:10 < Cracki> or it's just more convenient to have a cache handle stuff instead of explicitly copying stuff into CCM

2019-03-06T01:04:14 < jadew> BrainDamage, so what happens if you cool something down to below 0 K and then break the isolation?
2019-03-06T01:06:10 < jadew> will it heat up the environment as it heats up to 0 K itself? or will it suck entropy from the environment and at the same time... lose also entropy?
2019-03-06T01:12:41 < jadew> given that something that has negative temperature is hotter than infinity hot, it means that while it's heating up to 0, it should also heat up the environment, so it has to release entropy in order to get hot, but at the same time, putting energy into it, should decrease the entropy
2019-03-06T01:13:34 < jadew> so... both getting and losing energy makes it heat up...
2019-03-06T01:13:36  * jadew scratches head

2019-03-06T01:15:19 < jadew> I'm gonna take this to ##physics
2019-03-06T01:17:39 < mawk> putting more energy should make the temperature even more negative jadew 
2019-03-06T01:17:48 < mawk> you have even fewer micro-states available
2019-03-06T01:18:07 < jadew> mawk, but then again, how is it negative?
2019-03-06T01:18:20 < jadew> does it simply become infinity+ and stay there?
2019-03-06T01:18:28 < jadew> how do you get it back to 0?
2019-03-06T01:18:41 < mawk> I don't know about this infinity business, maybe it was vulgarisation
2019-03-06T01:18:42 < jadew> I assume that happens by heating up the environment
2019-03-06T01:18:54 < jadew> I don't think it is
2019-03-06T01:18:56 < mawk> also it's maybe a calculus artifact, you have other models that avoid negative temperatures
2019-03-06T01:19:10 < jadew> the idea is that anything below 0 K, is hotter than anything with a positive temperature
2019-03-06T01:19:30 < jadew> I don't think it's an artifact either
2019-03-06T01:19:41 < jadew> I think it's something like.. negative entropy
2019-03-06T01:20:18 < Cracki> breadboard of perfboard? (I'm sure there are perfboards in all kinds of rasters, I had 1.27mm some years ago)
2019-03-06T01:20:36 < mawk> well if you take another definition of entropy, other than S = k_B log Ω, you don't have negative temperatures
2019-03-06T01:20:46 < Cracki> negative temperature is probably just a mathematical construct, not intuitive
2019-03-06T01:20:48 < mawk> but you may have other problems
2019-03-06T01:22:07 < Cracki> the metal contact bridges for protoboard might get really hard to make quickly
2019-03-06T01:23:34 < Cracki> maybe abuse one of these https://mt.rsdelivers.com/product/te-connectivity/2102061-1/te-connectivity-mezalok-127mm-pitch-114-way-6-row/7825291
2019-03-06T01:24:28 < Cracki> kakimir, wat for?
2019-03-06T01:24:46 < kakimir> I would preffer 1/4 pin pitch
2019-03-06T01:24:58 < kakimir> but I just drill every second hole to tht board
2019-03-06T01:25:02 < Cracki> 0.635 mm wat
2019-03-06T01:25:09 < Cracki> that's as wide as standard pins
2019-03-06T01:25:15 < kakimir> 6.35
2019-03-06T01:25:33 < Cracki> what now, 1/4 inch pitch? that's huuuge
2019-03-06T01:25:41 < kakimir> yyes
2019-03-06T01:25:45 < Cracki> uuuh
2019-03-06T01:25:48 < kakimir> I need bulky things
2019-03-06T01:26:10 < Cracki> standard pin diameter, or more?
2019-03-06T01:26:38 < kakimir> pin diameter something like 1.8
2019-03-06T01:26:45 < kakimir> or to say
2019-03-06T01:26:54 < kakimir> I drill every hole to tht board
2019-03-06T01:26:56 < Cracki> wew that sounds like it's cheap to make custom
2019-03-06T01:27:14 < kakimir> it needs to be by weekend so I just drill
2019-03-06T01:27:18 < Cracki> some custom sheet metal clamp strips, a little 3d printing
2019-03-06T01:29:14 < Cracki> how do you feel about 0.22" or 0.28" pitch? that'd be standard 0.1" at 45 degrees
2019-03-06T01:29:30 < Cracki> but still 1.8mm legs would raep any breadboard

2019-03-06T02:14:46 < Cracki> including racing drones
2019-03-06T02:15:47 < zyp> still got that laptop in a box somewhere, maybe I should dig it out and put a neural network card in it
2019-03-06T02:16:11 < Cracki> those AI thingies are only good for inference tho, not learning
2019-03-06T02:16:30 < Cracki> (unless they actually mention fp32 crunch)
2019-03-06T02:16:59 < zyp> how does the computational load between inference and learning differ?
2019-03-06T02:17:33 < Cracki> inference is a single forward pass
2019-03-06T02:17:43 < Cracki> learning is a gazillion backwards passes
2019-03-06T02:18:10 < Cracki> forward passes can be done in low precision, even uint8
2019-03-06T02:18:16 < Cracki> if you juggle your network weights right
2019-03-06T02:18:32 < Cracki> but learning requires precision, i.e. fp32
2019-03-06T02:18:42 < zyp> ah, makes sense
2019-03-06T02:20:38 < zyp> does backward/forward imply different operations too?
2019-03-06T02:21:50 < zyp> I figure that number of passes doesn't matter, something that's faster at forward passes should be faster at backward passes too, unless those are different kinds of operations
2019-03-06T02:23:20 < Cracki> yes, forward is pretty much summing and applying activation/transfer function
2019-03-06T02:23:29 < zyp> apologies if I sound dumb, I don't know much about neural networks :)
2019-03-06T02:23:31 < Cracki> backwards is taking the derivative of that function and propagating the error
2019-03-06T02:23:38 < Cracki> I don't know much either, for now :P
2019-03-06T02:23:55 < Cracki> the derivative is usually known and a closed form
2019-03-06T02:24:15 < Cracki> still, this can fuck off fast thanks to numerical inaccuracies
2019-03-06T02:24:47 < kakimir> https://www.mouser.fi/datasheet/2/196/Infineon-ProductBrief_XMC_Link_Isolated_Debug_Prob-1274418.pdf
2019-03-06T02:24:49 < Cracki> something you can use for training has TONS of memory and is good at fp32 crunch
2019-03-06T02:25:19 < kakimir> if that works with other than xmc it's a solid deal
2019-03-06T02:25:25 < Cracki> those little edge devices are good at fp16, fp8, uint8 and might only have enough memory for that little bit of crunch they can do
2019-03-06T02:25:32 < zyp> if I were like ten-fifteen years younger, I'd have gotten into machine learning now and made it a career or something
2019-03-06T02:25:37 < Cracki> networks (their weights) can be megabytes upto gigabytes in size
2019-03-06T02:25:43 < Cracki> same :>
2019-03-06T02:26:02 < Cracki> I'll have to though. there's really no alternative for me.
2019-03-06T02:26:39 < zyp> I've filled my head with too much other crap now :p
2019-03-06T02:26:58 < Cracki> it's still the wild west so with a little "hard" work you know the basics and can probably run circles around anyone else
2019-03-06T02:27:23 < Cracki> the point of AI is that you will be able to swap all that crap out :P
2019-03-06T02:27:34 < zyp> speaking of other crap, I've spent hours today figuring out how the fuck to decrypt and encrypt zigbee packets
2019-03-06T02:28:00 < zyp> why is crypto documentation always so fucking unreadable?
2019-03-06T02:28:12 < Cracki> because hype attracts noobs which are eager but useless
2019-03-06T02:28:29 < Cracki> perhaps you're talking about library docs
2019-03-06T02:28:41 < zyp> no, mainly the zigbee spec itself
2019-03-06T02:28:50 < Cracki> library docs, any field, are probably impenetrable unless you've taken the courses or read the text books

2019-03-06T02:29:37 < Cracki> it kinda keeps the noobs away :P
2019-03-06T02:29:58 < zyp> cryptographers missed the note on variable naming, so everything is just named a single letter
2019-03-06T02:31:25 < Cracki> all math, all physics, even theoretical CS
2019-03-06T02:31:38 < Cracki> stuff is always \varphi_{something}
2019-03-06T02:32:36 < zyp> and then this bullshit tripped me up for a while: «The security level sub-field of the security control field shall be overwritten by the 3-bit all-zero string '000'.»
2019-03-06T02:32:57 < Cracki> oh looky, that movidius thing can do stereo vision at 720p and 180 hz
2019-03-06T02:33:21 < Cracki> stuff like that is dead simple to accelerate in silicon, but expensive on CPUs (and even still on ordinary gpus)
2019-03-06T02:33:32 < Cracki> the wat of the wat
2019-03-06T02:33:41 < zyp> so there's a field in the packet, but it's only used for encrypting and decrypting, but always transferred as 0 over the air
2019-03-06T02:33:50 < Cracki> so "sc.level is 3 bits"
2019-03-06T02:34:13 < Cracki> I hate prose in place of code
2019-03-06T02:34:14 < zyp> yeah, it's three bits of the security control flags
2019-03-06T02:35:05 < Cracki> aha! movidius only does fp16 and fix8 natively
2019-03-06T02:35:23 < Cracki> yeh they'd waste silicon giving it wider math
2019-03-06T02:35:33 < zyp> once I figured out what data to grab, how to massage it and where to feed it into AES, I wrote some code to pick apart packets: https://paste.jvnv.net/view/JreXR

2019-03-06T02:37:32 < zyp> been using that construct library for a couple of years now, I find that once I started using it, dealing with it in any other way is just annoying :p
2019-03-06T02:37:50 < Cracki> last time I had to touch crypto was when I needes aes-xcb (?) for an old truecrypt volume... disk repartitioning fucked up, so I needed to find that first sector again
2019-03-06T02:37:58 < zyp> hehe
2019-03-06T02:38:39 < Cracki> I've heard of construct before. seems like it has enough users to stay alive and evolving
2019-03-06T02:38:54 < zyp> the problem with crypto is that everything is designed to look like random data, so if only a single thing is fucked up somewhere, everything becomes wrong and it's impossible to figure out where
2019-03-06T02:39:04 < Cracki> hehehe indeed
2019-03-06T02:39:17 < Cracki> test vectors ftw

2019-03-06T02:39:58 < zyp> still got wrong results
2019-03-06T02:40:37 < zyp> had to go digging into the crypto library and add some prints of intermediate data to figure out where it went wrong

2019-03-06T02:40:57 < Cracki> always fun to dig around :>

2019-03-06T02:41:39 < Cracki> I had some "type" errors... in contemporary python, which has very little static type checking yet
2019-03-06T02:42:03 < zyp> I didn't realize that that 0008 to update() would be generated internally :p
2019-03-06T02:42:06 < Cracki> somewhere instead of the bytes themselves, I got 'Bytes("012345...")'
2019-03-06T02:42:29 < zyp> hehe
2019-03-06T02:43:37 < Cracki> maybe they do it on purpose, making you read the source. that gets your eyes on it, and makes you likelier to change it, and improve it, and contribute back
2019-03-06T02:44:23 < zyp> the other day, I looked at actually patching python
2019-03-06T02:44:27 < Cracki> o.o
2019-03-06T02:45:51 < zyp> sockets in python only supports a given list of address families, the C code behind the socket module got some functions with huge switches on the family
2019-03-06T02:46:58 < zyp> I want a AF_IEEE802154 socket, and there's not a case for that in those switches :p
2019-03-06T02:47:24 < Cracki> hah
2019-03-06T02:48:10 < zyp> it's possible to just feed the integer number for the address family to the socket creation call, but as soon as I try calling a method that would deal with an address like sendto() or recvfrom() it raises an exception
2019-03-06T02:49:54 < Cracki> seems to me like they need a generic fallback that just throws around bytestrings
2019-03-06T02:50:02 < zyp> it just needs a case added with some code to convert sockaddr_ieee802154 structs to and from some python object representation
2019-03-06T02:50:09 < Cracki> and that
2019-03-06T02:51:26 < zyp> might look at adding that later
2019-03-06T02:51:49 < zyp> I put it off for now and wrote some code doing the same in C++ with boost::asio instead
2019-03-06T02:52:17 < Cracki> in #opencv occasionally some eager newbies show up asking "what can I do to contribute". tasks such as this sound ideal.
2019-03-06T02:52:27 < Cracki> just extend existing code
2019-03-06T02:52:48 < Cracki> you *could* use ctypes to use whatever system calls you need directly
2019-03-06T02:53:41 < zyp> https://paste.jvnv.net/view/NU7Og <- asio was really straight forward about adding a new protocol
2019-03-06T02:54:35 < zyp> and yeah, I could use ctypes
2019-03-06T02:54:42 < Cracki> ctypes.windll.user32.MessageBoxW(0, "Hello World", "Hello World", 0)
2019-03-06T02:54:43 < zyp> I've considered that
2019-03-06T02:55:22 < Cracki> it's bare but simpler than starting what you need in cython
2019-03-06T02:55:38 < Cracki> interesting, asio...
2019-03-06T02:55:44 < zyp> but I'd like to use asyncio, and integrating ctypes calls to read/write sockets with the asyncio event loop sounds painful too
2019-03-06T02:56:09 < zyp> boost::asio is fairly similar in concept to python's asyncio module
2019-03-06T02:57:12 < zyp> but then again, it's C++, takes a lot more work to achieve the same as a few lines of python :p
2019-03-06T02:58:41 < zyp> the easiest short term solution is probably to just open an udp socket as well in the asio code and proxy packets between the udp socket and the 802.15.4-socket :p
2019-03-06T02:59:50 < zyp> bonus benefit with that is that the 802.15.4 radio is on a rpi, so the asio code runs there, and if the python code is decoupled through udp I can run it on my workstation
2019-03-06T03:00:45 < zyp> not sure how much impact the additional latency will have, idk how latency sensitive zigbee is
2019-03-06T03:04:56 < Cracki> interesting stuff
2019-03-06T03:05:19 < zyp> yeah

2019-03-06T11:05:06 < crispy> im reading through the datasheet of the stm32f427ii
2019-03-06T11:05:38 < crispy> i only find the amount of GPIO (in this case 140) but on other µC i get the extra information how many Analog Inputs i can use from them..
2019-03-06T11:06:13 < crispy> the datasheet says "On Chip peripheral current consumption "At startup, all I/O pins are in analog input configuration.""

2019-03-06T11:09:46 < emeryth> no
2019-03-06T11:09:47 < R2COM> no, only those marked AN
2019-03-06T11:10:00 < emeryth> analog input in this case does not mean ADC
2019-03-06T11:11:12 < crispy> ok there is no specific value to see the number of AIOs?

2019-03-06T11:12:25 < emeryth> the ADC has 16 external channels
2019-03-06T11:12:51 < zyp> crispy, 24
2019-03-06T11:13:50 < crispy> zyp: is this information in the datasheet?
2019-03-06T11:14:19 < zyp> yes, that's where I pulled it from
2019-03-06T11:14:29 < crispy> thanks! which site?
2019-03-06T11:14:32 < zyp> https://www.st.com/resource/en/datasheet/stm32f427ii.pdf <- bottom line on page 16
2019-03-06T11:15:25 < zyp> in that table you'll see that the 100-pin variant got 16 analog inputs, the larger ones got 24
2019-03-06T11:15:47 < zyp> the chip is the same in any case, it's just the 100-pin variant don't got the last 8 hooked up
2019-03-06T11:17:18 < crispy> Ok thanks!
2019-03-06T11:17:39 < crispy> i have to make a research about µCs and am a little confused about it
2019-03-06T11:17:55 < zyp> if you look at the pin table, you'll see that the ones missing from the 100pin variant are the ones on PF3-10 because those pins don't exist in the 100-pin package
2019-03-06T11:18:01 < crispy> to the GPIOS are independent of the AIOs?
2019-03-06T11:18:35 < R2COM> you can find a diagram of what IO is made of
2019-03-06T11:18:39 < zyp> yes, analog inputs are an additional function that's available on some pins
2019-03-06T11:19:16 < R2COM> oh shit its 2am
2019-03-06T11:19:21 < R2COM> i need to be in bed
2019-03-06T11:19:31 < crispy> ok, so i have to read it like that.. there a 3 ADC Ports, and every Port of the ADC has 16channels, (maybe multiplexed?) so i got 3x24 AIOs?
2019-03-06T11:19:48 < crispy> R2COM: :D its 10:30
2019-03-06T11:19:53 < zyp> crispy, that's not entirely correct
2019-03-06T11:20:30 < R2COM> look at alternate function table to see which pin can be used for which peripheral
2019-03-06T11:20:39 < zyp> there's three ADC peripherals, in front of each there's a 16-channel mux, and each input to the mux are hooked up to some pin
2019-03-06T11:21:06 < zyp> some pins are hooked up to inputs on all of the ADC peripherals, some of them are only hooked up to one or two of them
2019-03-06T11:21:37 < zyp> I believe there's 8 pins hooked up to all three, 8 pins hooked up to only ADC1 and ADC2 and 8 pins hooked up to only ADC3
2019-03-06T11:22:10 < crispy> ohman thats confusing^^

2019-03-06T11:23:10 < crispy> thats the information i need
2019-03-06T11:23:41 < zyp> 24
2019-03-06T11:24:06 < crispy> ah ok, so the 24 are for all 3 ADC
2019-03-06T11:24:37 < zyp> yes, 24 is the total number of externally available pins
2019-03-06T11:25:10 < crispy> ok! thx
2019-03-06T11:25:19 < crispy> and 2 DAC?
2019-03-06T11:25:55 < zyp> yes
2019-03-06T11:26:00 < zyp> can I ask what you're planning to do?
2019-03-06T11:26:44 < crispy> yes sure
2019-03-06T11:27:16 < dongs> btw, you can't sample all those at same time, hope you realize that
2019-03-06T11:27:19 < crispy> i have to create a overview of specific µCs used in some gears
2019-03-06T11:27:36 < dongs> its select and sample, then switch to next channel
2019-03-06T11:27:53 < zyp> dongs, but all that can be automated
2019-03-06T11:27:57 < dongs> ya sure
2019-03-06T11:28:08 < crispy> dongs: yes, i know. there are 2 ways to S&H them, i read about it
2019-03-06T11:28:17 < dongs> i mean select + dma into buffer, all automatic
2019-03-06T11:28:18 < crispy> simultaneous and interleaved 
2019-03-06T11:28:22 < zyp> can set up each ADC to sample 8 channels each, looping over them, continously
2019-03-06T11:28:43 < zyp> that way you'll sample three and three at a time
2019-03-06T11:29:27 < zyp> and everything can be DMAed into a buffer so you've got 24 samples being continously updated

2019-03-06T11:31:26 < dongs> diccolo
2019-03-06T11:31:29 < zyp> crispy, so anyway, you're not really gonna use these chips for anything, you're just doing research?
2019-03-06T11:31:33 < zyp> is this classwork or something?
2019-03-06T11:31:37 < crispy> zyp: yes
2019-03-06T11:31:41 < dongs> sounds like wank
2019-03-06T11:31:47 < crispy> just doing research
2019-03-06T11:31:55 < zyp> okay, fair enough
2019-03-06T11:32:10 < crispy> zyp: but im interested in starting programming with stm32
2019-03-06T11:32:31 < crispy> i already got a nucleo board but wanted to understand the hardware better first
2019-03-06T11:33:34 < zyp> hmm, I'm not sure what those TI specs mean
2019-03-06T11:33:57 < crispy> thats frustrating..
2019-03-06T11:34:07 < zyp> I haven't worked with TMS320, but I've worked with RM46 which IIRC is very similar to TMS570
2019-03-06T11:34:45 < zyp> but at a glance I'm guessing that AIO spec is unrelated and that the number of ADC Channels in the middle of the table is what's relevant
2019-03-06T11:34:51 < zyp> since that depends on package size
2019-03-06T11:35:40 < crispy> there are some specs i cant understand.. TI  says tconv is 216.67ns. ST say 0.5µs - 16.4µs depends on how many bits.. 
2019-03-06T11:35:54 < crispy> the µs range is for the whole ADC Bank i guess?
2019-03-06T11:36:14 < crispy> and the TI tconv is for one channel?
2019-03-06T11:36:17 < zyp> looking at the pinout drawings a few pages later, they have pins like ADCINB2/COMP1B/AIO10, so the AIO signals are apparently unrelated from the ADCIN signals
2019-03-06T11:36:21 < dongs> no, its single channel conversion
2019-03-06T11:36:38 < dongs> it depends on how many samples and ADC peripheral clock
2019-03-06T11:38:45 < zyp> yeah, conversion time is for a single conversion
2019-03-06T11:39:05 < crispy> ok so when i got 24 of them in a row i will need in worst case 24*16.4µs?
2019-03-06T11:39:22 < zyp> no
2019-03-06T11:40:18 < zyp> anyway, you choose the conversion time
2019-03-06T11:41:00 < crispy> ok, so when a voltage is at my Channel, my µC will need 0.5µs - 16.4µs to digitalize it?
2019-03-06T11:41:14 < dongs> yeah.
2019-03-06T11:41:27 < zyp> if you want 0.5us conversion time, you configure it to that, and since you have channels distributed across three ADCs, best case it'll take you 4us to read all 24
2019-03-06T11:41:45 < crispy> ahhh
2019-03-06T11:42:39 < crispy> so in that spec TI is faster
2019-03-06T11:43:08 < zyp> well, it says 4.6 MSPS for the one you're looking at, lower spec ones are 2.0 MSPS just like the stm32 you're looking at
2019-03-06T11:43:09 < crispy> just the µC im looking at right now, not in general
2019-03-06T11:43:33 < zyp> but if you are looking for ADC performance, you should probably be looking at stm32f3, not f4
2019-03-06T11:43:48 < zyp> f3 family is analog oriented
2019-03-06T11:44:21 < crispy> datasheet reading is a science for itself :D
2019-03-06T11:44:54 < qyx> or L4
2019-03-06T11:45:00 < qyx> they have 5Msps ADC too
2019-03-06T11:45:06 < zyp> let's see, f303 has up to 40 channels across 4 ADCs with 5 MSPS each
2019-03-06T11:45:17 < qyx> yes
2019-03-06T11:45:39 < crispy> zyp: how do you got that the TI 28034 is slower with the conversion than the ST?
2019-03-06T11:46:00 < crispy> conversion time of the TI is 216.67 ns and the ST 0.5µS
2019-03-06T11:46:06 < zyp> that's 40 channels in 2us total assuming channels are evenly distributed
2019-03-06T11:46:12 < zyp> crispy, I havent claimed that
2019-03-06T11:46:24 < crispy> ah ok sorry
2019-03-06T11:46:43 < dongs> that 0.2us for TI could also be the shittiest quality conversion
2019-03-06T11:46:53 < dongs> with like 4 enob
2019-03-06T11:46:59 < zyp> well, of course it is
2019-03-06T11:47:04 < zyp> the fastest is always the shittiest
2019-03-06T11:47:14 < crispy> dongs: i think so, but they dont give a range 
2019-03-06T11:47:25 < dongs> its not like youre gonna use it so it probly doesnt matter so much
2019-03-06T11:47:28 < crispy> ST and Renesas gives a range
2019-03-06T11:47:42 < dongs> friends dont let friends use renesas
2019-03-06T11:47:58 < crispy> :D why
2019-03-06T11:48:39 < zyp> crispy, you're kinda going about it the wrong way though
2019-03-06T11:49:01 < zyp> in the real world, you're not starting out looking for the fastest ADC with the most channels
2019-03-06T11:49:17 < crispy> zyp: no sure
2019-03-06T11:49:40 < crispy> zyp: maybe i have to say more about my work i have to do. 
2019-03-06T11:49:51 < zyp> in the real world, you start out with having a given number of channels that you want to sample at a given rate, and then you filter by parts being capable of doing that
2019-03-06T11:49:56 < dongs> like, there are also dedicated ADC chips
2019-03-06T11:50:04 < dongs> yeah
2019-03-06T11:50:08 < dongs> what zp said
2019-03-06T11:50:26 < zyp> and then pick whatever is most suitable out of the capable parts
2019-03-06T11:50:39 < crispy> im a student and i have to analyze the existing µC in the products we are assembling, to create a overview which controller we and our concurrent in the market uses
2019-03-06T11:51:14 < dongs> do you work for ST
2019-03-06T11:51:14 < crispy> i have written down a list of specs that are interesting and now im doing research
2019-03-06T11:51:20 < dongs> cuz that sounds like the kinda job they'd give to a ST intern
2019-03-06T11:51:22 < zyp> I think you overestimate the value of individual specs like that
2019-03-06T11:51:25 < dongs> instead of say, fixing shit in cube
2019-03-06T11:51:56 < crispy> dongs: :D if i would worked for ST i should more about µCs than i know now :D
2019-03-06T11:52:38 < crispy> zyp: that might be right, but i want to make a good overview
2019-03-06T11:52:59 < crispy> how deeper i get into the hardware specs, the more i learn
2019-03-06T11:54:25 < zyp> when I pick parts for a project, the first thing I look at is how easy they are to use
2019-03-06T11:54:50 < zyp> and the biggest part of that is how much new stuff I'll have to figure out to get started
2019-03-06T11:54:59 < dongs> zyp hates updating laks
2019-03-06T11:55:03 < zyp> haha
2019-03-06T11:55:03 < dongs> to new cores
2019-03-06T11:55:17 < zyp> not really
2019-03-06T11:55:22 < kakimir> babbys first multiple mcu system
2019-03-06T11:56:45 < zyp> the truth is that most of the big vendors have a fairly assorted range of parts, so for most projects you can get a suitable part from any vendor
2019-03-06T11:57:09 < dongs> if you pick that TI shit then you have to deal with crap composter
2019-03-06T11:57:16 < crispy> i want to get the number of channels on which i can Output a PWM signal.. on site 36. in the f427ii datasheet stands that the advanced-control-timers TIM1,TIM8 can be seen as three phase PWM generators multiplexed on 6 channels.
2019-03-06T11:57:20 < dongs> at least ST doesn't FORCE you to use cube and friends
2019-03-06T11:57:32 < dongs> the fuck is site 36
2019-03-06T11:57:33 < dongs> is that page?
2019-03-06T11:57:36 < dongs> you keep saying that
2019-03-06T11:57:41 < crispy> page*
2019-03-06T11:57:43 < dongs> it was site 6 on teh other shit
2019-03-06T11:57:48 < dongs> i was confused as fuck
2019-03-06T11:58:09 < dongs> you can get like 16 PWM outs from F103
2019-03-06T11:58:09 < zyp> dongs, if you pick TMS320, sure, but not if you pick any of the cortex-m based ones
2019-03-06T11:58:12 < dongs> in 48pin pckage
2019-03-06T11:58:18 < zyp> or cortex-r for that matter
2019-03-06T11:58:19 < crispy> so i can generate with TIM1, TIM8 3*6 PWM Signals ?
2019-03-06T11:58:24 < dongs> no
2019-03-06T11:58:30 < dongs> every timer has up to 4 channels
2019-03-06T11:58:35 < dongs> and there's usually a shitload of them
2019-03-06T11:58:40 < dongs> depending on package, you can have LOTS of pwm out.
2019-03-06T11:58:54 < crispy> how can a timer have channels?
2019-03-06T11:59:02 < dongs> it does
2019-03-06T11:59:03 < crispy> i thought it only counts up or down.. 16bit
2019-03-06T11:59:15 < zyp> capture/compare channels
2019-03-06T11:59:15 < dongs> yes, so it has several counters doing that.
2019-03-06T11:59:29 < zyp> each timer has one counter and a number of capture/compare channels
2019-03-06T11:59:38 < crispy> one timer TIM1, hat 4 subTimer which are counting ?
2019-03-06T11:59:42 < dongs> no
2019-03-06T11:59:43 < zyp> no
2019-03-06T11:59:50 < dongs> also i think tim1 only has 3 cahnnels
2019-03-06T11:59:53 < zyp> for PWM you configure the timer to count on a cycle
2019-03-06T12:00:09 < crispy> ok, not 4 but a various number of counters?
2019-03-06T12:00:10 < zyp> and each compare channel has a value that gets compared to the counter
2019-03-06T12:00:13 < dongs> but other general purpose shit like tim3/4/5/232839048 has up to 4 dependign on package
2019-03-06T12:00:48 < zyp> and then each channel has an output that is high or low depending on whether the compare value is higher or lower than the timer value
2019-03-06T12:01:17 < crispy> ah ok, so with one counter i can set the value of some channels?
2019-03-06T12:01:27 < zyp> so you can set the timer to count to 0-999 at 1 MHz, set channel 1 to 250 and channel 2 to 500
2019-03-06T12:01:46 < zyp> then you'll get two square outputs at 1 kHz, one at 25% duty and one at 50% duty
2019-03-06T12:02:54 < crispy> ah ok.. so in general i can use the timer like that: i configure it so count from 0-999 at 1Hz, if the value is lower than 100 i can set Channel 1 high, if the value is between 101-500 i can reset CH1 and Set CH2
2019-03-06T12:03:02 < crispy> is this right, that i can do it like that?
2019-03-06T12:03:15 < zyp> no, there's no «between»
2019-03-06T12:03:21 < zyp> just higher or lower
2019-03-06T12:03:49 < crispy> ah ok, so i can set/reset the channels of my timer just with the expressions lower/higher=
2019-03-06T12:04:08 < zyp> I mean
2019-03-06T12:04:42 < zyp> the timers are pretty complex, you can do a lot with them if you get creative
2019-03-06T12:04:57 < zyp> but if you just want a bunch of pwm outputs, all that is irrelevant
2019-03-06T12:06:27 < crispy> ok!
2019-03-06T12:07:01 < crispy> so i want to declare the maximum number of PWM output signals i can generate with the 427ii
2019-03-06T12:07:09 < zyp> the main difference between timers and channels when doing pwm is that while you can set duty per channel, frequency is set per timer
2019-03-06T12:07:28 < zyp> hmm
2019-03-06T12:07:46 < crispy> zyp: ok that sounds logic
2019-03-06T12:08:00 < crispy> The advanced-control timers (TIM1, TIM8) can be seen as three-phase PWM generators
2019-03-06T12:08:00 < crispy> multiplexed on 6 channels
2019-03-06T12:08:14 < dongs> the 3 channels on TIM1 are useless
2019-03-06T12:08:16 < crispy> i know that there are 2 independet PWM channels for motor control
2019-03-06T12:08:16 < dongs> teh negative ones
2019-03-06T12:08:20 < dongs> they're inverse of the positive 
2019-03-06T12:08:25 < dongs> so you don't have as much control over them.
2019-03-06T12:08:29 < zyp> dongs, also TIM1 also got four channels
2019-03-06T12:08:33 < dongs> oh does it?
2019-03-06T12:08:36 < zyp> yeah
2019-03-06T12:08:45 < dongs> even with capcom out? oh well. i was too lazy to look
2019-03-06T12:08:50 < zyp> I think I did a count once and concluded f4 could do twenty-something channels
2019-03-06T12:08:52 < crispy> "Their 4 independent channels can be used for"
2019-03-06T12:08:54 < dongs> but i think urrite, cuz i've used TIM1_Ch4 before for sure
2019-03-06T12:09:03 < crispy> input capture, output compare, pwm gen, one-pulse mode output
2019-03-06T12:09:09 < zyp> we were considering stm32 for the workproject before going for TI RM4
2019-03-06T12:09:46 < crispy> what does it meen "three phase PWM generators muxed on 6chans"
2019-03-06T12:10:20 < zyp> haha
2019-03-06T12:10:27 < zyp> I think it's just marketing wank
2019-03-06T12:10:49 < zyp> it means you can use it to generate timings for driving three phase motors
2019-03-06T12:10:54 < crispy> hehe ok, so they got the right one (me) :D someone who dont have any knowledge
2019-03-06T12:11:49 < zyp> my TI RM4 got 28 PWM outputs hooked up
2019-03-06T12:11:53 < crispy> ah ok, "twelve general-purpose16-bit timers including two PWM timers for motor control" so TIM1 and TIM8 are the 2 PWM timers for control
2019-03-06T12:12:28 < zyp> although half of them are not doing pwm at all
2019-03-06T12:12:45 < zyp> IIRC f407 can also do 28
2019-03-06T12:13:19 < zyp> unless you run into a conflict with other functions you need that are only available on the same pins

2019-03-06T12:24:47 < crispy> ok, is that in fact for every µC? i cant find any information on the TMS320 about configuring the ADC to 10bit res
2019-03-06T12:25:48 < qyx> it depends on the adc
2019-03-06T12:26:48 < crispy> "12-Bit Analog-to-Digital Converter (ADC)" means that the core of the ADC is realised with 12bit res
2019-03-06T12:27:00 < crispy> and it cant be configured working with 10bit res?

2019-03-06T12:48:59 < jpa-> do you have a resistor in parallel with the transducer?
2019-03-06T12:50:03 < qyx> I have 2x47K connected to vdda and gnd, so yes
2019-03-06T12:56:05 < qyx> I suspect the cover
2019-03-06T12:56:25 < jpa-> piezos do resonate a lot, though
2019-03-06T12:56:34 < jpa-> is it at the specified resonant frequency or something else?
2019-03-06T12:56:36 < qyx> it looks like it is vibrating
2019-03-06T12:57:03 < qyx> it is such thing https://cdn.sparkfun.com//assets/parts/4/6/8/9/10293_01.jpg
2019-03-06T12:57:10 < qyx> nothing like a resosnant freq
2019-03-06T12:58:07 < qyx> murata says 9kHz for a similar one
2019-03-06T12:58:23 < qyx> this is resonating at <1kHz

2019-03-06T12:59:04 < jpa-> but for piezos, electrical resonance always equals mechanical resonance anyway
2019-03-06T13:00:49 < qyx> I'll insert something furry inside

2019-03-06T13:02:48 < jpa-> and you can't get rid of resonances altogether; you can either try to move it out of the band you are interested in, dampen it with lossy material to reduce the Q and thus oscillation time, or just filter it out of the signal later in processing

2019-03-06T13:08:32 < jpa-> hmm.. perhaps it was acoustic then

2019-03-06T13:13:31 < justMaku> hey there, yet another episode of justMaku trying to get the damned i2c bus to work
2019-03-06T13:13:50 < justMaku> i managed to get the devices to communicate, but it's totally random
2019-03-06T13:14:04 < justMaku> if i reset the stm32 enough times, it will eventually start reading/writing on the bus
2019-03-06T13:14:26 < justMaku> so my question is: what would be the best place to find a freelancer willing to do this properly for money
2019-03-06T13:14:45 < jpa-> _o/ hire me
2019-03-06T13:15:03 < jpa-> or freelancer.com!

2019-03-06T13:18:32 < justMaku> jpa-: what would be a reasonable price for this? I literally need a basic example of stm32 waiting for a command on i2c bus to appear and then replying with some data

2019-03-06T13:21:07 < justMaku> and i'm not sure what you mean by software libs
2019-03-06T13:21:39 < jpa-> are you using e.g. cubemx, some rtos, just stm32f038.h and register defs?

2019-03-06T13:23:46 < justMaku> i thought I could handle this and everything was going fairly well until the point I got hit the i2c bus
2019-03-06T13:25:01 < justMaku> the stm32 is a slave device in this context, the master is an nrf52 that expects data on the bus and sends it through the BLE
2019-03-06T13:25:35 < justMaku> i got it to ~work~ but it's totally unreliable for any purposes
2019-03-06T13:25:38 < jpa-> i can do it for 200 EUR fixed price or 60 EUR/hour; including review of your existing code and fixing & testing it to work, + support if you'll have any problems applying it to your hardware; i have some STM32F042 here I can use to test it

2019-03-06T14:07:41 < jadew> one of the many setbacks I had with one of my current projects is when china let me know that they gave me the wrong quote for a custom machined part
2019-03-06T14:07:48 < jadew> it was off by %500
2019-03-06T14:08:26 < jadew> kinda ruined my margin

2019-03-06T14:14:30 < jadew> here's something interesting, that should make you think about other sources of wasted time, even if this particular thing doesn't apply to you
2019-03-06T14:14:52 < kakimir> wasting time
2019-03-06T14:15:10 < jadew> I did the math today and my wife spends 30 wake-days (16-hour day) in traffic, every year
2019-03-06T14:15:22 < jadew> that's a month out of 12
2019-03-06T14:16:02 < jadew> this alone is a very good incentive to move away from this city
2019-03-06T14:16:38 < kakimir> what citi
2019-03-06T14:16:43 < jadew> Bucharest
2019-03-06T14:17:17 < jadew> everything seems to be far enough, mainly because of the traffic
2019-03-06T14:18:07 < kakimir> citi is not the place
2019-03-06T14:20:46 < jadew> thing is, all wasted time adds up
2019-03-06T14:21:07 < jadew> and I'm sure you can find lots of ways to optimize
2019-03-06T14:21:13 < jpa-> 2 hours a day?
2019-03-06T14:21:18 < jadew> jpa-, yeah
2019-03-06T14:21:24 < jadew> not taking weekends into account
2019-03-06T14:21:31 < jadew> just the work days
2019-03-06T14:21:48 < jpa-> yep, my mom does similar commute every day and has been doing it for years
2019-03-06T14:22:04 < jpa-> for me, 30 minutes of biking each way was long enough :P
2019-03-06T14:22:32 < jadew> at least you were biking, so that time was not completely wasted

2019-03-06T14:24:52 < jadew> living and working in a small town is probably ideal
2019-03-06T14:25:23 < kakimir> I waste 5minutes a day to commuting

2019-03-06T14:30:34 < Laurenceb> > UK ‘porn block’ starts April 1 – but you can unlock it by handing over ID or buying £5 ‘porn licence card’ on your local high street
2019-03-06T14:30:41 < Laurenceb> my sides, the memes are real
2019-03-06T14:32:36 < jadew> Laurenceb, better get yours soon, before they run out
2019-03-06T14:35:29 < jpa-> "Websites which are more than one-third pornographic"   haha, so now they'll just need 75% of "articles" :)
2019-03-06T14:37:27 < jpa-> i can't see how under 18 year olds could possibly get hold of such a "porn license card", this scheme is perfect
2019-03-06T14:38:51 < Laurenceb> or just use vpn 
2019-03-06T14:39:51 < Laurenceb> oi m8 wheres ur pron loicense
2019-03-06T14:42:07 < jadew> lmfao, you have to be 18 to watch porn? haha
2019-03-06T14:42:35 < Laurenceb> kek 4chan /pol/ are supporting this
2019-03-06T14:43:20 < Laurenceb> >We should ban literally all porn that involves real human beings, it's all made by the jews, is exploitative, ruins people lives, messes up peoples brain psychology to turn them into pedos.
2019-03-06T14:44:53 < jadew> pantyhose labels will be back in demand in the UK?
2019-03-06T14:45:09 < Laurenceb> probably
2019-03-06T14:48:46 < Laurenceb> >*rings up the local porn control officer*
2019-03-06T14:51:42 < jpa-> i wonder why people are still in denialism about porn and under-18-year-olds

2019-03-06T14:51:49 < englishman> doing it wrong
2019-03-06T14:52:19 < jpa-> it would make much more sense to separate porn like everything else into different categories, nice porn that would be like 12 or 10 year old limit, and Laurenceb-porn that would be 21+
2019-03-06T14:52:52 < Laurenceb> ^spotted the pedo
2019-03-06T14:53:13 < Laurenceb> >10 year olds
2019-03-06T14:53:25 < jpa-> .. limit for the people watching, not the people performing :)
2019-03-06T14:53:30 < Laurenceb> kek
2019-03-06T14:53:41 < PaulFertser> englishman: I live in Moscow but I wasn't able to find a way to reliably get to job place in less than 1:40 using public transport but it's about 45 minutes on motorbike.
2019-03-06T14:53:44 < jadew> yeah, when I was 12, I was watching soft-core
2019-03-06T14:53:48 < jadew> that's all there was
2019-03-06T14:54:07 < Laurenceb> kekking tbh https://imgoat.com/uploads/ae27d77ca2/204037.png
2019-03-06T14:54:08 < jadew> and the occasional hot-line commercials
2019-03-06T14:55:10 < jadew> englishman, yeah, but she has to make a detour to the kindergarten too
2019-03-06T14:55:33 < jadew> everything is just far
2019-03-06T14:57:32 < Laurenceb> spotted the porn control officer https://imgoat.com/uploads/ae27d77ca2/204038.jpg
2019-03-06T14:58:04 < PaulFertser> englishman: another example: my relatives live about 25km away from me, the route is via a straight motorway. It took me 1:30 to get there yesterday (going to bus stop, waiting for bus, going from bus stop) while it's normally about half an hour on motorbike.
2019-03-06T14:59:29 < jpa-> public transit for daily commute feels like fail also, optimal would be to live close enough to bike or walk
2019-03-06T14:59:52 < jpa-> unless it's a particularly fast and often operated line
2019-03-06T15:00:43 < kakimir> assuming you live in country were is good light trafic routes and well established public transport
2019-03-06T15:02:29 < kakimir> also city - suburb planning can make use of bicycle unusable option
2019-03-06T15:03:15 < jpa-> yeah, fail does not necessarily depend on personal choices
2019-03-06T15:03:24 < jpa-> some cities are total fail :P
2019-03-06T15:11:35 < zyp> hmm, farnell sent me an export form to fill out, for the stm32wb nucleo
2019-03-06T15:12:14 < zyp> apparently they arrived in stock at RS today, almost tempted to cancel my farnell order and reorder at RS instead, but they cost more at RS
2019-03-06T15:12:44 < jadew> zyp, just because of the export form?
2019-03-06T15:13:00 < zyp> no, because farnell don't expect them back in stock before next month
2019-03-06T15:13:03 < kakimir> such a friction
2019-03-06T15:13:20 < kakimir> it just doesn't fit modern time and age
2019-03-06T15:13:24 < zyp> RS would presumably send me the same form
2019-03-06T15:13:39 < kakimir> ridiculous
2019-03-06T15:13:46 < jadew> so cancel
2019-03-06T15:13:58 < jadew> there's no point in waiting that long
2019-03-06T15:14:14 < kakimir> order from europe zypster
2019-03-06T15:14:31 < zyp> huh?
2019-03-06T15:14:39 < zyp> both RS and farnell are european
2019-03-06T15:14:56 < zyp> warehouse in UK
2019-03-06T15:15:04 < kakimir> what is the export form for?
2019-03-06T15:15:13 < zyp> crypto
2019-03-06T15:15:27 < zyp> stm32wb comes with hardware AES and shit
2019-03-06T15:15:31 < kakimir> ye
2019-03-06T15:16:05 < kakimir> I thought it was just yankee thing
2019-03-06T15:16:28 < zyp> well
2019-03-06T15:16:41 < jpa-> weird that hardware crypto is export controlled
2019-03-06T15:16:55 < jpa-> the speed advantage is not that much anyway
2019-03-06T15:16:59 < zyp> the difference between american and european distributors is that from european distributors you get a form to fill out, from american distributors you get told to fuck off
2019-03-06T15:17:19 < kakimir> okay
2019-03-06T15:17:33 < zyp> jpa-, my understanding is that it's not hardware crypto in itself that's export controlled, it's the crypto algorithms
2019-03-06T15:17:52 < zyp> it's just that you can't export control software in a sane way

2019-03-06T15:25:56 < dongs> i can also poke china ST people taht I used to buy F103s from before, they'd have an official source

2019-03-06T16:25:51 < zyp> heh, farnell asked me if I wanted them to send the second item (that I only added to the order to come above the free shipping limit) now instead of waiting to ship with the stm32wb nucleo
2019-03-06T16:26:01 < Laurenceb> it'd probably be about 50 times faster if I created fake channels "lag1, lag2" etc
2019-03-06T16:26:11 < zyp> I told them sure as long as I don't have to pay any extra shipping for it
2019-03-06T16:26:28 < Laurenceb> then uploaded "samples" at<1khz
2019-03-06T16:26:33 < zyp> so now I'm getting my free shipping order padding item shipped separately, for free

2019-03-06T16:42:48 < Cracki> wat https://docs.influxdata.com/influxdb/v1.7/guides/writing_data/#writing-multiple-points
2019-03-06T16:43:04 < Cracki> is that not what you want
2019-03-06T16:43:20 < Laurenceb> yeah thats what I'm doing
2019-03-06T16:43:26 < Laurenceb> still horrible slow
2019-03-06T16:43:45 < Laurenceb> its averaging about realtime atm
2019-03-06T16:44:26 < Cracki> as of august 2018, it seems to want to stay a web hipster piece of shit and won't take binary data
2019-03-06T16:44:42 < Laurenceb> ikr
2019-03-06T16:44:45 < Laurenceb> so much fail
2019-03-06T16:44:57 < Cracki> so how many values per sec will it consume?
2019-03-06T16:45:10 < Laurenceb> about 100k
2019-03-06T16:45:25 < Laurenceb> would probably be faster if I ran the uploader on the server
2019-03-06T16:45:32 < Cracki> ¯\_(ツ)_/¯
2019-03-06T16:45:51 < Cracki> good, now I have a number to remember. someone I talked to seemed to think influx was fast
2019-03-06T16:46:08 < Cracki> it's probabvly fast considering all the overhead
2019-03-06T16:46:26 < Cracki> (and it's the wrong tool for isochronously sampled data)
2019-03-06T16:46:30 < zyp> 100k values per second is quite a lot of data
2019-03-06T16:46:44 < zyp> and yeah, it's the wrong tool
2019-03-06T16:46:48 < Laurenceb> ikr
2019-03-06T16:46:54 < qyx> you have to take into consideration Laurenceb is abusing a tsdb for waveform storage
2019-03-06T16:46:57 < Laurenceb> its what I'm paid to do

2019-03-06T16:47:36 < Cracki> have you considered using a cluster and sharding and fidding
2019-03-06T16:47:39 < BrainDamage> if not, just keep fucking around as long as you're paid
2019-03-06T16:47:41 < Laurenceb> no because everyone else is even more fail

2019-03-06T16:48:45 < Laurenceb> yeah
2019-03-06T16:49:09 < jadew> sounds like a good deal
2019-03-06T16:49:23 < Cracki> if they scrapped those actually hired to do the work, they'd have to scrap the ones merely "managing" them too
2019-03-06T16:49:31 < Laurenceb> guess I could rewrite the uploader in c...
2019-03-06T16:49:42 < Cracki> what's it written in now
2019-03-06T16:49:48 < Laurenceb> python
2019-03-06T16:50:08 < Cracki> some dude from google recently wrote a paper on Ryu, a very fast float to ascii conversion algorithm
2019-03-06T16:50:10 < qyx> I am not sure if it helps
2019-03-06T16:50:17 < Laurenceb> not sure quite where the bottleneck is
2019-03-06T16:50:17 < Cracki> python shouldn't be too bad
2019-03-06T16:50:23 < Laurenceb> yeah, my cpu isnt pegged atm
2019-03-06T16:50:29 < qyx> your network overhead is worse probably
2019-03-06T16:50:39 < Laurenceb> its uploading about 4MB/s, network is faster than that
2019-03-06T16:50:40 < zyp> Laurenceb, not even a single core?
2019-03-06T16:50:49 < Laurenceb> zyp: its 8 core
2019-03-06T16:50:54 < qyx> I mean tcp and http and pps and things
2019-03-06T16:50:54 < jadew> Laurenceb, you can profile this sort of stuff
2019-03-06T16:50:59 < Cracki> remember python is single core, so you have to check process time. individual cores might never beg because scheduler bounces the hot one around
2019-03-06T16:51:03 < Laurenceb> jadew: yeah good idea
2019-03-06T16:51:08 < zyp> yeah, but your uploader is singlethreaded
2019-03-06T16:51:17 < Cracki> pipelining perhaps
2019-03-06T16:51:26 < Cracki> at 4 MB/s latency might already affect you
2019-03-06T16:51:28 < BrainDamage> when you do your test, make sure to set core affinity
2019-03-06T16:51:33 < Cracki> if a request isn't all that large
2019-03-06T16:51:34 < qyx> also, you are basically doing 100k HTTP requests per second, aren't you?
2019-03-06T16:51:39 < BrainDamage> so that the process doesn't get moved around
2019-03-06T16:51:43 < Laurenceb> zyp: I wrote a hacky bash script to spawn about 16 threads of the uploader
2019-03-06T16:51:46 < Cracki> he isn't, multiple values per POST
2019-03-06T16:51:51 < zyp> oh, okay
2019-03-06T16:52:01 < Cracki> still, it's ascii
2019-03-06T16:52:08 < Laurenceb> all uploading from different points into the file
2019-03-06T16:52:35 < Cracki> tbh I'd look into hacking some binary data ingest onto that thing
2019-03-06T16:52:48 < Cracki> spares you the conversion on both ends
2019-03-06T16:53:03 < Laurenceb> heh yeah it needs rf64 import tbh
2019-03-06T16:53:17 < Laurenceb> thats what I'm trying to put into it
2019-03-06T16:53:17 < Cracki> fuck them if they don't want to take the patch
2019-03-06T16:53:29 < Cracki> rf64 meaning riff64, i.e. wave files?
2019-03-06T16:53:33 < Laurenceb> yes
2019-03-06T16:53:43 < Laurenceb> yuuuge ones
2019-03-06T16:53:47 < Laurenceb> like 20GB
2019-03-06T16:53:48 < Cracki> that might require a wave file parser on the other end
2019-03-06T16:54:01 < jadew> Laurenceb, why do you want to store them in a DB tho?
2019-03-06T16:54:06 < jadew> that's not how it's done
2019-03-06T16:54:07 < Cracki> simpler would be to pipe the raw samples into it, and send sample rate etc as header
2019-03-06T16:54:12 < Laurenceb> jadew: cuz managers said so
2019-03-06T16:54:32 < Laurenceb> jadew: my plan was to extract metadata from the rf64, then store metadata on the database
2019-03-06T16:54:33 < jadew> take some initiative and tell them they don't know what they're talking about
2019-03-06T16:54:41 < jadew> exactly
2019-03-06T16:54:43 < Laurenceb>  :P
2019-03-06T16:54:45 < Cracki> does influx have optimization for isochronous samples, or is it actually storing the sample time for every sample?
2019-03-06T16:54:46 < jadew> and you store the file on the disk
2019-03-06T16:55:11 < Laurenceb> Cracki: it stores sample time, but its faster for samples that are sorted in time
2019-03-06T16:55:28 < Cracki> or can it only store sequences without timestamp
2019-03-06T16:55:32 < Laurenceb> jadew: yeah it only needs a interface to find the files matching a specific set of metadata
2019-03-06T16:55:50 < jadew> precisely, what you need there is an API
2019-03-06T16:56:08 < Cracki> in your place I'd definitely look into (1) building influx myself (2) hacking some special case for binary isochronous samples
2019-03-06T16:56:10 < jadew> putFile(), getFile(), search(), or whatever
2019-03-06T16:56:14 < Laurenceb> its supposed to be semi n00b friendly
2019-03-06T16:56:17 < Cracki> it can generate time indices itself
2019-03-06T16:56:26 < Laurenceb> so web interface that grabs the data
2019-03-06T16:56:48 < jadew> Laurenceb, web interfaces can make use of the API too
2019-03-06T16:56:53 < Laurenceb> yeah
2019-03-06T16:57:23 < jadew> it's just that you disconnect the user code from the storage
2019-03-06T16:57:44 < jadew> so you become free to store shit wherever you want and however you think it makes more sense
2019-03-06T16:58:25 < Laurenceb> audiodata,configuration=ResearchTrolley,Harness_selector=NeoRestraint,Mattress_selector=New_sponge Chan1=-0.0013 1550763196682792960
2019-03-06T16:58:30 < Laurenceb> this is retarded
2019-03-06T16:58:59 < Laurenceb> all that for <16 bits of data
2019-03-06T16:59:19 < Cracki> I think his overlords specified "influxdb" by name so the only way forward is to completely change it so only the name remains
2019-03-06T16:59:33 < Laurenceb> heh ""influxdb""
2019-03-06T17:05:00 < zyp> dongs, heh, just got an email from LL guy, apparently his customer are dicking around with some CE bullshit and needs to document that everything is conforming to RoHS
2019-03-06T17:05:18 < dongs> oh, np
2019-03-06T17:05:35 < dongs> uh, yo uneed what , certs on what solder i use and shit?
2019-03-06T17:05:45 < dongs> and pcb datasheet?
2019-03-06T17:05:59 < zyp> yeah, shit like that
2019-03-06T17:06:04 < dongs> ok ill gather some filth up
2019-03-06T17:06:10 < dongs> LL was 4L righT?
2019-03-06T17:06:14 < zyp> yes
2019-03-06T17:06:17 < dongs> kk
2019-03-06T17:07:27 < dongs> i should have something by monday
2019-03-06T17:07:38 < zyp> ok, cool
2019-03-06T17:07:43 < dongs> solder i can get anytime but pcb nigger is in hokkaido snowborading
2019-03-06T17:07:59 < BrainDamage> Laurenceb: can you use any time series db or does it have to be influxdb?
2019-03-06T17:08:22 < Laurenceb> BrainDamage: IT guy on the project uses Influx for his other stuff
2019-03-06T17:08:34 < kakimir> 0.16V could that be concidered safe logic low?
2019-03-06T17:08:42 < Laurenceb> so he wants to use it for this as its all running on his server
2019-03-06T17:08:43 < dongs> pretty safe yea
2019-03-06T17:08:48 < kakimir> nic
2019-03-06T17:13:44 < zyp> dongs, hmm, apparently components also
2019-03-06T17:14:23 < dongs> well, you can look up that they're rohs by the BOM right? the resistors are from RoyalOhm
2019-03-06T17:14:29 < dongs> ill see what caps but mostly samsung
2019-03-06T17:14:31 < dongs> all that shit is ROhs
2019-03-06T17:14:51 < zyp> yeah, I figured as much, just don't know the vendor for the passives
2019-03-06T17:15:06 < jadew> pretty sure all passives are RoHS now
2019-03-06T17:15:28 < zyp> sure, but CE assholes needs proof

2019-03-06T17:16:07 < bitmask> what was I thinking?
2019-03-06T17:16:07 < jadew> also, you can just say it's any resistor, they can't check
2019-03-06T17:16:12 < zyp> anyway, if you just have the mfg of the passives I can send the list to the guy and he can deal with looking it up
2019-03-06T17:16:23 < dongs> yas, ill get
2019-03-06T17:16:39 < dongs> like i said resistorsa re all royalohm and caps ill dig through the list/reels and see
2019-03-06T17:16:45 < dongs> but like 90% samsung 
2019-03-06T17:16:50 < dongs> if not 100
2019-03-06T17:16:58 < zyp> sounds good
2019-03-06T17:18:06 < rajkosto> what even isnt rohs anymore
2019-03-06T17:21:24 < dongs> some stuff they use in california
2019-03-06T17:21:48 < bitmask> do they use BeO in anything anymore?
2019-03-06T17:23:02 < jadew> don't know if BeO is still commonly used, but beryllium is still used in a lot of stuff
2019-03-06T17:24:41 < rajkosto> mercury is good
2019-03-06T17:24:42 < rajkosto> lead is good
2019-03-06T17:24:51 < rajkosto> rohs was a mistake
2019-03-06T17:25:10 < jadew> I agree
2019-03-06T17:25:27 < jadew> or maybe they shouldn't have banned lead from electronics
2019-03-06T17:25:33 < jadew> at least that...
2019-03-06T17:26:43 < rajkosto> the trace amount in solder is no hazard
2019-03-06T17:26:49 < rajkosto> it was only beacuse of lead paint and lead in gasoline
2019-03-06T17:27:10 < rajkosto> the tiny amount of mercury vapor in CCFLs is no problem either
2019-03-06T17:27:28 < jadew> lead in gasoline was solved a long time ago
2019-03-06T17:27:35 < jadew> when they figured people were going insane because of it
2019-03-06T17:28:15 < emeb> my understanding is that metallic lead isn't nearly as dangerous as lead componds - oxides, etc.
2019-03-06T17:28:53 < rajkosto> rohs was amended to allow cadmium in quantum dots
2019-03-06T17:31:21 < rajkosto> silly to just ban elements outright
2019-03-06T17:35:02 < rajkosto> whats the problem with berillyium
2019-03-06T17:36:24 < BrainDamage> beryllium oxide is super toxic and carcinogen, and there's multiple records where a single inhalation gave lifelong lung issues
2019-03-06T17:36:35 < Laurenceb> oi m8 wher is ur element loicense
2019-03-06T17:37:11 < BrainDamage> sorry, single exposure, not single inhalation
2019-03-06T17:37:29 < jadew> well, that's pretty much the same
2019-03-06T17:37:50 < rajkosto> how many electronic devices would need to explode for a single inhalation
2019-03-06T17:38:05 < bitmask> one old microwave
2019-03-06T17:38:06 < jadew> rajkosto, a tiny amount of that dust can cause this
2019-03-06T17:38:09 < BrainDamage> one 30 year old magnetron
2019-03-06T17:38:16 < jadew> for example, a cracked magnetron
2019-03-06T17:38:30 < rajkosto> yeah but magnetrons have such a cool name they are excused
2019-03-06T17:39:37 < jadew> it's many 10s of times more toxic than cyanide
2019-03-06T17:39:42 < qyx> yeah sounds good, killed by a magnetron
2019-03-06T17:44:26 < Cracki> WAT r u saying zyklon b was cough drops?
2019-03-06T17:46:10 < BrainDamage> compared to eg. ricin, sure
2019-03-06T17:46:27 < BrainDamage> 2mg can kill you
2019-03-06T17:46:29 < Cracki> it killed lice alright
2019-03-06T17:46:45 < Cracki> and fleas, or whatever these buggers were

2019-03-06T19:23:52 < dongs> G0 hs analog PD shit
2019-03-06T19:23:57 < dongs> or else yo u need over 9000 passives around it

2019-03-06T19:24:12 < dongs> you *can* do PD with 103 its just gonna be aids

2019-03-06T19:52:16 < dongs> as in memset it to 0xff
2019-03-06T19:52:19 < dongs> it only sets 1st element.
2019-03-06T19:52:23 < dongs>  0, memsets to zero.
2019-03-06T19:52:57 < zyp> {0xff} would be equivalent to {0xff, 0, 0, …};

2019-03-06T19:53:39 < dongs> is the last part in spec?

2019-03-06T20:04:29 < zyp> well, sure, legacy PD used sideband comms on vbus line
2019-03-06T20:04:40 < zyp> don't think anything supports taht though :p
2019-03-06T20:04:58 < zyp> but usb-c stuff with PD is fairly common
2019-03-06T20:05:05 < zyp> even my fucking phone charger does PD
2019-03-06T20:05:06 < englishman> how does my phone do fast charging? how much power is that?
2019-03-06T20:05:33 < zyp> I mean, my phone charger is designed to also be able to charge laptops
2019-03-06T20:05:53 < zyp> idk what your phone does, there's tons of standards it can use
2019-03-06T20:06:11 < zyp> plain usbc does 3A@5V
2019-03-06T20:06:25 < englishman> it's plugged into my computer's usbA 3.0 port
2019-03-06T20:06:37 < englishman> so not any special samsung stuff
2019-03-06T20:06:46 < dongs> then you arent gonna get any PD at all
2019-03-06T20:06:51 < englishman> right
2019-03-06T20:06:55 < zyp> plugged into your computer it's probably limited by BC
2019-03-06T20:07:09 < zyp> or even usb2 itself, giving you 500mA
2019-03-06T20:07:19 < englishman> def more than 2.5W
2019-03-06T20:07:28 < zyp> then BC
2019-03-06T20:07:43 < englishman> nothing in this stusb4500 doc about legacy charging
2019-03-06T20:07:53 < zyp> because it's irrelevant
2019-03-06T20:08:02 < englishman> no it isnt
2019-03-06T20:08:13 < dongs> yes it is
2019-03-06T20:08:29 < englishman> if I plug my pd device into a usbA port it still needs to draw more than 2.5W
2019-03-06T20:08:30 < zyp> the devices PD are meant for doesn't give a fuck about legacy charging
2019-03-06T20:08:35 < dongs> it can't
2019-03-06T20:08:39 < englishman> wtc
2019-03-06T20:08:48 < englishman> so there is zero backwards compatibility
2019-03-06T20:09:05 < dongs> it will just draw whatever until it trips the ptc/current limited usb port switc hthingy.
2019-03-06T20:09:08 < zyp> what sort of backwards compatibility do you want?
2019-03-06T20:09:26 < englishman> a pd device can never charge at more than usb1.1 spec except with full PD spec
2019-03-06T20:09:32 < zyp> there's no legacy standards that will provide as much power as PD
2019-03-06T20:09:32 < englishman> is what you're saying?
2019-03-06T20:09:33 < dongs> true
2019-03-06T20:09:42 < zyp> no
2019-03-06T20:09:47 < dongs> it *can* do shit with BC
2019-03-06T20:09:51 < dongs> using usbdm/dp stuff
2019-03-06T20:09:56 < dongs> thats how shitty chink phoens do it
2019-03-06T20:10:02 < dongs> like huawei etc.
2019-03-06T20:10:03 < zyp> you can do BC or QC or whatever shit is available on your A port if you really care
2019-03-06T20:10:07 < dongs> yeah
2019-03-06T20:10:21 < englishman> QC is samdongs stuff
2019-03-06T20:10:28 < zyp> qualcomm
2019-03-06T20:10:32 < dongs> there's also one by MTK
2019-03-06T20:10:34 < dongs> and Huawei
2019-03-06T20:10:50 < dongs> Huawei does 40W over that
2019-03-06T20:10:55 < englishman> so I need both, a pd controller on CC lines and legacy BC controller 
2019-03-06T20:11:06 < dongs> if you want leet stuff, yes
2019-03-06T20:11:10 < dongs> are you doing a sink or a source?
2019-03-06T20:11:13 < zyp> yeah, if you really need your device to work with A hosts
2019-03-06T20:11:21 < dongs> i did that battery pack charger thing with a bunch of chink ICs
2019-03-06T20:11:33 < dongs> that do BC, QC negotiation
2019-03-06T20:11:34 < englishman> dont give a shit about this niche stuff, it needs to charge when plugged into 99% of devices which means a computer
2019-03-06T20:11:45 < dongs> then just draw shit and not care
2019-03-06T20:11:57 < zyp> do you even need >5V?
2019-03-06T20:12:04 < zyp> if 5V is enough for you, you don't need PD
2019-03-06T20:12:15 < dongs> maybe measure VUSB and if it starts dropping below say 4.8V, you're probly drawing too much
2019-03-06T20:12:17 < englishman> only for pd, I can give a lower spec when plugged into a usbA but not 2.5W
2019-03-06T20:12:26 < zyp> dongs, BC limit is lower
2019-03-06T20:12:37 < dongs> yeah?> what is it i dont know
2019-03-06T20:12:42 < zyp> then just do a combination of BC and PD
2019-03-06T20:13:13 < zyp> BC is mostly «monitor vbus and limit your current draw so it doesn't drop below x V
2019-03-06T20:13:16 < zyp> »
2019-03-06T20:13:21 < englishman> nice
2019-03-06T20:13:53 < zyp> there's also some shit to check that you're connected to a BC host, but I'm not sure how important that is
2019-03-06T20:14:35 < zyp> usb spec requires hosts to not take damage from overcurrent, so if you draw too much and host craps itself, it's out of spec :p
2019-03-06T20:15:07 < zyp> I mean, you would be too, but who cares :p

2019-03-06T23:15:53 < Steffanx> Damn. Such english
2019-03-06T23:21:00 < zyp> aandrew, you're not limited by CDC, but by what's allowed for the underlying bulk endpoints

2019-03-06T23:26:27 < jpa-> Steffanx: it was actually from libgsm and already unrolled; but in the actual code, even if i don't unroll it, gcc tends to do partial unrolling

2019-03-06T23:30:04 < jpa-> http://paste.dy.fi/Xez/plain   this is also kind of strange, what's up with loading stuff to r7 and then moving to fp?
2019-03-06T23:32:51 < zyp> I'm guessing short ldr only targets low registers?
2019-03-06T23:33:14 < zyp> I think there's a ldr.w, but ldr+mov might be just as cheap maybe?
2019-03-06T23:34:03 < zyp> I mean, of course there's a ldr.w, you've got that too :p
2019-03-06T23:35:30 < zyp> jpa-, are you using intrinsics or something for that smlad, or did the compiler generate that too?
2019-03-06T23:35:31 < jpa-> hmm yeah, maybe that's it
2019-03-06T23:35:37 < jpa-> intrinsic
2019-03-06T23:36:18 < jpa-> i think i'll just write the whole inner loop in assembly and ldm them all into registers
2019-03-06T23:36:37 < zyp> to me this looks like badly interfaced inline assembly
2019-03-06T23:37:23 < zyp> which suggests poor use of constraints in the intrinsics implementation
2019-03-06T23:37:45 < jpa-> __asm__("smlad %0, %1, %2, %3" : "=r" (a) : "r" (x), "r" (y), "r" (a) );  is the intrinsic i'm using
2019-03-06T23:38:07 < jpa-> it seems to be using the registers quite freely in the disassembler output though
2019-03-06T23:38:39 < jpa-> i think main problem is that it doesn't realize it would make sense to spill registers before the inner loop so that it wouldn't have to reload and move stuff around all the time
2019-03-06T23:38:53 < jpa-> no reason why it couldn't use all of r0..r7
2019-03-06T23:46:26 < zyp> why did you even hand unroll it?
2019-03-06T23:49:22 < zyp> also, why are you giving negative indices to dp? is that by design?
2019-03-06T23:50:14 < zyp> and why are there 40 weights, but you're only using 32?
2019-03-06T23:51:12 < zyp> ah
2019-03-06T23:51:40 < zyp> I realized what the compiler is doing
2019-03-06T23:52:06 < zyp> hmm, no, disregard
--- Day changed Thu Mar 07 2019
2019-03-07T00:11:44 < zyp> jpa-, by the way
2019-03-07T00:12:17 < zyp> is this actual real code, or a simplified example?
2019-03-07T00:13:00 < zyp> because if this is real code, you should realize that you end up multiplying every value in dp with each weight exactly once, except for the values in the beginning and the end
2019-03-07T00:13:41 < zyp> so you might as well add together all the weights first and multiply every value just once, and then fix the end cases or something
2019-03-07T00:14:28 < upgrdman> anyone know of a tool for monitor usb usage? e.g. i want a live chart of how many Mbps a usb device is doing, etc.
2019-03-07T00:14:33 < upgrdman> for windows
2019-03-07T00:14:59 < zyp> have you checked whether usblyzer can do that?
2019-03-07T00:15:10 < aandrew> zyp: I thought maybe the spec limited the endpoint depth; USB FS does have a 64 byte limit though
2019-03-07T00:15:22 < upgrdman> i have not. will check. thx zyp
2019-03-07T00:16:33 < zyp> aandrew, spec only allows a few given sizes for bulk endpoints, you can't choose arbitrarily up to that limit either
2019-03-07T00:16:48 < zyp> 64 for FS and 512 for HS
2019-03-07T00:17:10 < zyp> and then people who like arguing says FS also allows 32, 16 and 8 or some shit like that
2019-03-07T00:17:14 < zyp> but nobody cares about that
2019-03-07T00:18:00 < aandrew> zyp: interesting
2019-03-07T00:18:20 < zyp> it makes sense
2019-03-07T00:18:47 < aandrew> I'm running into some trouble on nrf52 where I seem to quite easily fill the upstream (to PC) buffer and it seems to take forever to transfer
2019-03-07T00:19:08 < aandrew> I mean I'm dumping packet data and there just isn't that much radio data I'm converting to ascii and dumping, but it won't keep up
2019-03-07T00:19:18 < zyp> only control and bulk does multi-packet transfers, and spec mandates them to be a power of two size
2019-03-07T00:19:27 < aandrew> I did find some speed improvements but nothing that's getting me near 12Mbps I don't think
2019-03-07T00:19:30 < zyp> which makes the modulo operation for packet splitting cheap
2019-03-07T00:19:43 < zyp> for iso and interrupt, spec allows arbitrary sizes
2019-03-07T00:20:11 < zyp> so I assume that limitation in the spec is to simplify hardware implementations
2019-03-07T00:21:04 < zyp> aandrew, how did you design your protocol?
2019-03-07T00:21:52 < zyp> by ascii I assume you're sending this over an ACM pipe?
2019-03-07T00:22:02 < zyp> how do you split the stream into packets?
2019-03-07T00:22:46 < zyp> do you send each line in a packet so you get a bunch of <64B packets, or do you send mainly 64B packets?
2019-03-07T00:22:57 < aandrew> it's not a protocol per se, unless you're talking the RF stuff. radio interrupt is just copying packets into a queue, and my main loop tries to empty the queue. basically while (pull_packet(&p) == 0) { convert_to_ascii_hex(p, str); write_to_tty(str, strlen(str));
2019-03-07T00:23:14 < aandrew> write_to_tty() copies the string into the outgoing USB data queue

2019-03-07T00:23:29 < aandrew> neither
2019-03-07T00:23:49 < zyp> I mean, what packet size actually ends up on the bus?
2019-03-07T00:24:10 < aandrew> when I get a "usb transmit complete" callback I grab up to 64 bytes from the outgoing queue and create a USB packet from it
2019-03-07T00:24:44 < aandrew> so it will always send endpoint-lengh-sized USB packets if that much is available, but will obviously send less if there are none
2019-03-07T00:24:50 < zyp> okay, so you end up with mostly 64B packets
2019-03-07T00:24:55 < aandrew> correct
2019-03-07T00:25:13 < aandrew> len = nrf_queue_out(&cdc_from_app, buf, sizeof(buf));
2019-03-07T00:25:19 < aandrew> app_usbd_cdc_acm_write(&m_app_cdc_acm, buf, len)
2019-03-07T00:25:21 < zyp> that should let you use the capacity of the bus optimally
2019-03-07T00:25:53 < aandrew> yes, so the limitation is likely to be something in the nordic implementation
2019-03-07T00:26:06 < zyp> how so?
2019-03-07T00:26:23 < aandrew> if it's slow to send or slwo to tell me I can send more
2019-03-07T00:26:59 < zyp> are you actually keeping the queue full enough to keep usb going without slowing down?
2019-03-07T00:27:32 < aandrew> that's a good question. I have to benchmark that
2019-03-07T00:27:50 < aandrew> basically dd if=/dev/ttyusbmodem of=/dev/null bs=64
2019-03-07T00:28:33 < zyp> I mean, if you're not overflowing the buffer on the device, usb manages to keep up
2019-03-07T00:28:55 < zyp> usb can't go faster than you actually have data to feed it
2019-03-07T00:29:06 < aandrew> hm I thought dd had an option to tell me the data rate
2019-03-07T00:29:28 < zyp> if you wanna just benchmark, just have the device send a constant 64B buffer over and over again
2019-03-07T00:29:41 < aandrew> I am having trouble where I am getting data dropped
2019-03-07T00:29:47 < zyp> okay
2019-03-07T00:30:11 < zyp> maybe you should consider getting a beagle or something, helps a lot for debugging shit like this
2019-03-07T00:30:12 < aandrew> if I modify my code to spin until it can send everything, I drop data going INTO the queue because I'm taking too long to send it
2019-03-07T00:30:27 < aandrew> yeah I was able to use a beagle at one contract. it was really nice
2019-03-07T00:30:29 < qyx> aandrew: dd if.. | pv > /dev/null
2019-03-07T00:31:09 < qyx> or send USR1 to dd and it prints some stats
2019-03-07T00:31:33 < qyx> watch killall -USR1 dd
2019-03-07T00:31:41 < qyx> or something ike that
2019-03-07T00:31:53 < aandrew> yep pv was what I was looking for
2019-03-07T00:32:13 < zyp> a trace from the beagle would make it immediately obvious whether it's the device that's not sending as fast as the bus allows, or if there's other issues resulting in the device not being polled as often as you'd like
2019-03-07T00:32:28 < aandrew> yep
2019-03-07T00:32:33 < aandrew> too bad they're so damned expensive

2019-03-07T00:34:23 < zyp> hmm, I think he's had one of my old fpga devboards for about just as long, although that only cost a fraction of what the beagle does :p
2019-03-07T00:36:39 < catphish> so here's a dull question i ask from time to time: is anyone working on anything interesting and/or have any ideas for anything that would benefit from collaboration?
2019-03-07T00:36:58 < zyp> interesting is always relative
2019-03-07T00:37:14 < zyp> my newest hobby project is hacking up a zigbee stack
2019-03-07T00:37:26 < catphish> i always end up working on stuff alone and never finish it
2019-03-07T00:38:11 < catphish> i thought zigbee was kind of a "buy a module and you're done" deal
2019-03-07T00:38:20 < zyp> well, yeah
2019-03-07T00:38:33 < catphish> or are you looking to build something atop it
2019-03-07T00:38:56 < aandrew> hm, dumping thorugh pv seems to say 22kB/sec
2019-03-07T00:39:11 < zyp> my end goal is making better light switches than what are available on the market at the moment, and I could probably acheive that the quickest if I just bought some module and added a bit of firmware to it to make it do what I want
2019-03-07T00:39:29 < zyp> but that's not very fun
2019-03-07T00:39:32 < aandrew> zyp: I was looking at that too
2019-03-07T00:39:52 < aandrew> basically I want a US-style NOT FUCKING DECORA light switch that didn't look like a dong sticking straight out
2019-03-07T00:40:08 < zyp> what's decora?
2019-03-07T00:40:19 < aandrew> it's trivial to have it behave like a normal fucking three way switch but every fucking smart switch has the paddle stick straight out
2019-03-07T00:40:23 < aandrew> the flat style
2019-03-07T00:40:34 < catphish> zyp: i always forget what is based on what, is zigbee used by existing commercial stuff? like hue?
2019-03-07T00:40:39 < zyp> yes
2019-03-07T00:40:51 < zyp> hue and ikea lights are both based on zigbee light link
2019-03-07T00:41:26 < catphish> i love hue, always fancied building something compatible
2019-03-07T00:41:45 < zyp> I like the ikea ones, same features at a fraction of the price
2019-03-07T00:42:07 < zyp> aandrew, I'm not very familiar with american light switch style
2019-03-07T00:42:44 < catphish> i believe these are hue compatible too https://www.innrlighting.com/en/
2019-03-07T00:43:32 < catphish> ie https://shop.innrlighting.com/en/shop/138/smart-bulb-white-e27-z3.0
2019-03-07T00:43:36 < catphish> for much less money
2019-03-07T00:43:39 < zyp> catphish, reason I wanna build my own switches is that I want some that can both communicate with a central thing so I can send event triggers out of the zigbee system, but also talk directly to the lamps themself so I won't be stuck unable to turn on/off any lights if the central shit crashes for any reason
2019-03-07T00:44:00 < zyp> there's plenty of shit on the market that can do one or the other of those, but not both
2019-03-07T00:44:32 < catphish> i have stock hue, i have genuinely no idea how messages get from switch to lamps
2019-03-07T00:44:46 < catphish> ie whether they have to go via the hue "hub"
2019-03-07T00:45:09 < zyp> I think they also talk directly
2019-03-07T00:45:27 < zyp> same as the ikea ones do
2019-03-07T00:45:30 < catphish> i guess i could easily turn off the hub and test
2019-03-07T00:46:36 < catphish> so how easy / hard is it to build a zigbee transceiver?
2019-03-07T00:47:14 < zyp> well, the physical layer is 802.15.4, so just get a radio for that, the rest is software
2019-03-07T00:47:38 < zyp> I've ordered a stm32wb nucleo, planning to prototype on that

2019-03-07T00:48:28 < qyx> by the time it arrives there are commercialy available switches with all your features :P
2019-03-07T00:48:39 < zyp> they fit in the standard 55mm switch frames we use here in norway
2019-03-07T00:48:54 < zyp> so I won't have to deal with mechanical design bullshit
2019-03-07T00:49:03 < zyp> just make a radio module to stick on the back of it
2019-03-07T00:50:06 < zyp> that'll give me six buttons per unit, two to turn directly connected lights on/off/up/down
2019-03-07T00:50:11 < zyp> and four to send event triggers
2019-03-07T00:50:18 < zyp> or however I end up configuring it

2019-03-07T00:51:50 < catphish> how do you intend to power it? battery with tx only on demand?
2019-03-07T00:51:50 < zyp> looks the same, but they don't have the features I want :p
2019-03-07T00:52:08 < zyp> well, yeah, like any other zigbee light switch
2019-03-07T00:52:18 < zyp> they only need to tx when you push it, after all
2019-03-07T00:52:32 < catphish> yeah my hue ones seem to have unlimited battery, i guess they wake on demand
2019-03-07T00:53:16 < zyp> I picked up a spare ikea remote and cracked it open, they are efr32 based
2019-03-07T00:53:55 < catphish> efr32 is bluetooth according to my googling
2019-03-07T00:53:57 < zyp> I first thought about just writing a new firmware for that, but I concluded efr32 seems too annoying to work with, so I dropped that idea
2019-03-07T00:54:09 < zyp> ble is also based on 802.15.4
2019-03-07T00:54:18 < zyp> so hardware that can do one can also do the other
2019-03-07T00:54:33 < catphish> oh, they say "multiprotocol sub-GHz and 2.4 GHz"
2019-03-07T00:54:39 < catphish> so i guess pretty flesible
2019-03-07T00:54:43 < catphish> *flexible
2019-03-07T00:55:06 < zyp> pretty much any low-rate 2.4G stuff is 802.15.4-based
2019-03-07T00:55:16 < zyp> zigbee, ble, 6lowpan/thread, etc…
2019-03-07T00:55:30 < catphish> that's interesting
2019-03-07T00:56:01 < zyp> why reinvent radio framing when you can just reuse and put a new network layer on top of it
2019-03-07T00:56:05 < catphish> we had a conversation at work about whether we could make a multiprotocol IoT hub, didn't realise it was tha easy
2019-03-07T00:57:05 < catphish> ie a replacement for the hue internet connected hub, but with support for products on other protocols
2019-03-07T00:57:48 < catphish> does that mean you could receive a frame without even knowing what ptotocol it balongs to?
2019-03-07T00:58:07 < qyx> sub1g is the way, I love it

2019-03-07T00:59:37 < zyp> no need to mess around with hardware design, just plug it in, load the .dts for the module and get a wpan0 network interface
2019-03-07T00:59:47 < zyp> then just open a 802.15.4-socket
2019-03-07T01:00:00 < zyp> except that stuff is not super mature, but it works :p
2019-03-07T01:00:36 < zyp> oh, and the ikea remote I cracked open got useful even if I'm not gonna develop on that
2019-03-07T01:00:54 < catphish> can i use that module with an stm32?
2019-03-07T01:01:08 < zyp> I dumped the flash from it and dug through it until I figured out where it stored the network key that my ikea lights are using
2019-03-07T01:01:13 < catphish> i guess pi might be nice for wireshark though
2019-03-07T01:01:28 < zyp> and then just plugged into wireshark, so it's now decrypting all my traffic
2019-03-07T01:01:47 < zyp> yeah
2019-03-07T01:01:50 < zyp> module is just spi
2019-03-07T01:02:08 < zyp> I just like the plug/play form factor for early prototyping

2019-03-07T01:09:21 < catphish> how does one authenticate to a light bulb?
2019-03-07T01:09:32 < zyp> dunno, haven't gotten that far yet
2019-03-07T01:09:49 < kakimir> authenticate light bulb
2019-03-07T01:10:02 < kakimir> what has world become
2019-03-07T01:10:14 < zyp> some exchange happens during pairing, giving the bulb a copy of the key the rest of the network is using
2019-03-07T01:10:27 < zyp> probably a bunch of handshakes and shit
2019-03-07T01:12:34 < zyp> I'll figure that out eventually
2019-03-07T01:13:09 < catphish> i can't remember how pairing works, or how one would re-pair
2019-03-07T01:13:12 < zyp> first I wanna work out how to talk to the devices I've got with the key I've already stolen
2019-03-07T01:13:37 < zyp> ikea stuff is touchlink based, i.e. hold the devices close together to authenticate them to each other
2019-03-07T01:13:47 < catphish> also, ebay seems short of cheap 802.15.4 modules :(
2019-03-07T01:14:16 < zyp> just grab a stm32wb nucleo or something :p
2019-03-07T01:14:34 < zyp> rs got them in stock now
2019-03-07T01:14:46 < catphish> stm32wb has integrated 802.15.4?
2019-03-07T01:14:56 < zyp> I'd cancel my farnell order and reorder at rs if not for the fact that farnell is cheaper :p
2019-03-07T01:15:00 < zyp> yeah
2019-03-07T01:15:13 < catphish> https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/stm32-nucleo-expansion-boards/p-nucleo-wb55.html?icmp=tt10667_gl_lnkon_feb2019
2019-03-07T01:15:36 < catphish> nice, antenna baked into the board of the nucleo
2019-03-07T01:16:41 < catphish> weird nucleo board though, my nucleo has a detachable programmer, this is somewhat different
2019-03-07T01:17:21 < zyp> still got programmer, not just detachable anymore
2019-03-07T01:17:21 < catphish> also, how come you have the exact same local suppler as UK?
2019-03-07T01:17:25 < catphish> ah ok
2019-03-07T01:17:36 < zyp> duh, I'm ordering from UK :p
2019-03-07T01:17:58 < catphish> farnell shows P-NUCLEO-WB55 in stoc
2019-03-07T01:18:00 < catphish> *stock
2019-03-07T01:18:31 < zyp> wait, wat
2019-03-07T01:18:34 < zyp> yeah, it does
2019-03-07T01:18:35 < zyp> wtf
2019-03-07T01:18:41 < catphish> lol
2019-03-07T01:19:09 < zyp> farnell sent me an email earlier today, offering to split my order and send my other shit in advance
2019-03-07T01:19:23 < zyp> which I accepted, so I'll have the other shit tomorrow
2019-03-07T01:19:26 < catphish> i can get it next-day"
2019-03-07T01:19:45 < zyp> but okay, maybe they'll send it tomorrow so I'll have it friday then
2019-03-07T01:20:03 < catphish> yeah could have just come in stock tonight
2019-03-07T01:20:13 < zyp> must have
2019-03-07T01:20:22 < kakimir> https://www.youtube.com/watch?v=oHNKTlz1lps youtube recommended me
2019-03-07T01:20:42 < catphish> zyp: remind me where you are?
2019-03-07T01:20:46 < zyp> norway
2019-03-07T01:21:00 < catphish> oh, not far away at all :)
2019-03-07T01:21:17 < catphish> i need to plan a holiday up there
2019-03-07T01:21:36 < zyp> https://www.ups.com/track?loc=en_US&tracknum=1Z2X069F0482840954/trackdetails <- here's the other shit they sent me today
2019-03-07T01:22:33 < catphish> wow you get next-day from uk?
2019-03-07T01:22:36 < catphish> that's impressive
2019-03-07T01:22:41 < zyp> apparently :)
2019-03-07T01:22:56 < catphish> that stuff you send me by cheap post only took about 3 days iirc
2019-03-07T01:23:06 < zyp> UPS deliveries from digikey and mouser takes two days
2019-03-07T01:23:16 < zyp> one day to get from US to EU, and another to get here
2019-03-07T01:23:41 < catphish> international mail sure has got fast
2019-03-07T01:23:52 < catphish> i get DHL from china in 2 days :)
2019-03-07T01:23:59 < zyp> been like that for the past ten years or so
2019-03-07T01:24:24 < catphish> lol well ok
2019-03-07T01:24:33 < zyp> probably longer, but >10 years ago I lived in the north of norway meaning everything takes a day or two extra to get from Oslo to there :p
2019-03-07T01:25:15 < catphish> so where's nice for vacation in norway?
2019-03-07T01:25:33 < kakimir> package can travel across the world 2days and then it takes 2 days to travel across the swamps
2019-03-07T01:25:41 < zyp> dunno, I tend to leave norway when I have vacation
2019-03-07T01:26:04 < catphish> i booked something in greece for next year, but fancy a cold vacation too
2019-03-07T01:26:10 < zyp> well, not entirely true, been plenty around in norway too
2019-03-07T01:26:24 < zyp> I guess it depends what you're looking for
2019-03-07T01:26:47 < zyp> for nature, west coast and the north is the prettiest
2019-03-07T01:27:14 < catphish> ideally: nature + quiet, with reasonable access to something more interesting for the odd evening out
2019-03-07T01:27:46 < zyp> how will you be getting around?
2019-03-07T01:27:48 < catphish> but i could always plan 2 locations, city, then on to the coast
2019-03-07T01:28:02 < catphish> i imagine rent a car from airport
2019-03-07T01:28:48 < zyp> I guess somewhere in the vicinity of Stavanger or Bergen then
2019-03-07T01:28:53 < catphish> i imagine renting a car from the airport, driving to somewhere quiet, or spending a night or 2 in the city first
2019-03-07T01:29:39 < catphish> mostly interested in the nature, will likely go in the winter to catch some snow
2019-03-07T01:29:58 < zyp> hmm, okay, I'm not familiar with vinter destinations
2019-03-07T01:30:12 < catphish> not compulsory though :)
2019-03-07T01:30:30 < zyp> I pretty much only fly up north to visit my parents when I'm going anywhere during winter :p
2019-03-07T01:31:00 < zyp> if you happen to be going somewhere along the south coast, you should stop by here :p
2019-03-07T01:31:18 < catphish> well i'll check out the west coast for locations with cabins that aren't ridicuoously far out from the cities
2019-03-07T01:31:50 < zyp> I figure there'll be plenty
2019-03-07T01:32:18 < zyp> I stayed a couple of nights at a cabin outside bergen when I were on a road trip a couple of years ago
2019-03-07T01:32:30 < catphish> the broken up land on the west coast does look nice
2019-03-07T01:32:40 < catphish> around bergen
2019-03-07T01:32:45 < zyp> yeah
2019-03-07T01:33:47 < zyp> https://bin.jvnv.net/file/HY3e8.png <- we did a two week tour of norway in 2015
2019-03-07T01:34:19 < zyp> started in the south, spent two days getting to the northernmost point, then the rest of the time getting back
2019-03-07T01:35:13 < catphish> zyp: is this efr32? https://www.ebay.co.uk/itm/Silicon-Laboratories-802-15-4-Development-Board/263420919379?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dcbf5614888d74be4a6c68ea416409684%26pid%3D100675%26rk%3D1%26rkt%3D15%26sd%3D263420919379%26itm%3D263420919379&_trksid=p2481888.c100675.m4236&_trkparms=pageci%3A7380fb45-4068-11e9-a67f-74dbd180d5db%7Cparentrq%3A555c28ce1690ad4a9290d356fff2831b%7Ciid%3A1

2019-03-07T01:35:54 < catphish> cheap, no information provided at all
2019-03-07T01:35:59 < zyp> hmm, dunno
2019-03-07T01:36:19 < zyp> I believe silabs also makes standalone transceivers
2019-03-07T01:36:31 < zyp> so it might be a plain mcu with a transceiver
2019-03-07T01:36:31 < catphish> looks like it has separate mcu and radio ICs
2019-03-07T01:36:37 < catphish> yeah i was just thinking that
2019-03-07T01:36:51 < zyp> or it might be one mcu acting as a programmer for an efr32
2019-03-07T01:37:01 < zyp> ah, no
2019-03-07T01:37:02 < catphish> i fact it has test pads for the interface betwen the 2
2019-03-07T01:37:08 < zyp> yeah, it's spi
2019-03-07T01:37:12 < catphish> yeah
2019-03-07T01:37:18 < zyp> separate transceiver for sure then
2019-03-07T01:37:52 < zyp> looks old, was probably even made before silabs bought out energy micro
2019-03-07T01:38:03 < catphish> does the stm32 actully have the transceiver on-chip?
2019-03-07T01:38:09 < catphish> including phy?
2019-03-07T01:38:12 < zyp> yes
2019-03-07T01:38:29 < catphish> awesome, might buy one of those then
2019-03-07T01:38:44 < zyp> oh, hey, the RM is out now
2019-03-07T01:39:00 < zyp> rev4 even
2019-03-07T01:39:03 < catphish> ?
2019-03-07T01:39:12 < zyp> the RM was not out two weeks ago
2019-03-07T01:39:38 < zyp> I asked an ST rep about it and got a prerelease copy, rev2
2019-03-07T01:39:58 < catphish> rm?
2019-03-07T01:40:36 < zyp> reference manual
2019-03-07T01:40:47 < zyp> ah, it was released march 1.
2019-03-07T01:40:50 < catphish> ah
2019-03-07T01:40:57 < catphish> for the STM32WB55?
2019-03-07T01:41:06 < zyp> yes
2019-03-07T01:41:12 < zyp> entire thing is really new
2019-03-07T01:42:26 < catphish> oh ok
2019-03-07T01:42:37 < catphish> and no legs, because st hates me
2019-03-07T01:43:08 < zyp> only thing I don't like about it is that the radio registers are not documented
2019-03-07T01:43:20 < zyp> so you have to rely on a driver blob for that
2019-03-07T01:43:21 < catphish> that seems impractical
2019-03-07T01:43:38 < catphish> why would st not document it?
2019-03-07T01:43:41 < zyp> not too bad since it'll run on its own cpu
2019-03-07T01:43:54 < zyp> well, it seems to be fairly usual
2019-03-07T01:44:02 < zyp> situation is the same with efr32
2019-03-07T01:44:16 < zyp> except efr32 only got one cpu, so driver needs to be linked into your firmware
2019-03-07T01:44:26 < catphish> so is it basically a separate radio IC jammed in the package?
2019-03-07T01:44:34 < zyp> stm32wb? no
2019-03-07T01:44:49 < zyp> it's a full dual cpu system, pretty fancy stuff
2019-03-07T01:45:09 < zyp> you could run your own stuff on both cpus too
2019-03-07T01:45:09 < catphish> well thats good, but one has to install a binary blob to run the radio on its own core?
2019-03-07T01:45:19 < englishman> like nordick
2019-03-07T01:45:31 < catphish> i guess if it works thats not the end of the world
2019-03-07T01:45:35 < zyp> yeah
2019-03-07T01:45:42 < catphish> but i hate shit like tha
2019-03-07T01:45:45 < zyp> same
2019-03-07T01:45:48 < englishman> fucking altidumb 19 is a pile of shit
2019-03-07T01:45:54 < englishman> speaking of blobs
2019-03-07T01:46:03 < zyp> I hope that at some point I can reverse engineer the radio interface
2019-03-07T01:46:57 < catphish> i guess this is still more efficient than an external spi transceiver
2019-03-07T01:47:13 < zyp> although the blob seems to be encrypted as well, so I'm not sure how easy it'll be to get at the code to decrypt it
2019-03-07T01:47:36 < catphish> but why? :|
2019-03-07T01:47:57 < catphish> does this mean they bought an IP block from someone else who is a dick?
2019-03-07T01:47:59 < zyp> idk, show off their fancy new IP protection mechanisms perhaps
2019-03-07T01:48:13 < zyp> dunno
2019-03-07T01:48:16 < catphish> or is ST doing this on purpose
2019-03-07T01:48:46 < zyp> I figure it might be licensing requirements, to prevent people from abusing the radio hardware
2019-03-07T01:49:18 < zyp> after all, this shit is not restricted to ST
2019-03-07T01:49:36 < zyp> but eh, I'll worry about that later
2019-03-07T01:49:47 < catphish> wow, someone near me is selling a pc with 8 x 1060 cards in it
2019-03-07T01:49:53 < zyp> either way, stm32wb has at least one cpu I can run blob free
2019-03-07T01:50:02 < zyp> sounds like they got tired of mining ethereum
2019-03-07T01:50:12 < catphish> that's some serious math coprocessing there
2019-03-07T01:50:16 < zyp> or whatever it is people mine nowadays
2019-03-07T01:50:25 < catphish> yeah i guess that's the case
2019-03-07T01:50:40 < catphish> £1,312 for 8 1060s isn't a bad price
2019-03-07T01:51:14 < catphish> no idea what one would do with them, choose a crypto currency and hope for the best
2019-03-07T01:51:21 < catphish> or render a movie :)
2019-03-07T01:51:49 < zyp> catphish, btw, I think you'll like this: https://www.st.com/resource/en/application_note/dm00600032.pdf
2019-03-07T01:52:38 < catphish> ah nice
2019-03-07T01:53:27 < catphish> that's fairly minimal :)
2019-03-07T01:53:45 < zyp> yeah, I like that
2019-03-07T01:54:04 < catphish> 2 crystals needed?
2019-03-07T01:54:50 < zyp> depends on what you're doing, I guess
2019-03-07T01:55:08 < catphish> LSE probably isn't compulsory
2019-03-07T01:55:19 < catphish> HSE probably is for the rF
2019-03-07T01:55:22 < zyp> yes

2019-03-07T01:56:02 < zyp> for a battery device that'll spend most time sleeping, you'll be turning off HSE, so you probably want LSE if you need accurate timekeeping
2019-03-07T01:56:16 < zyp> but you might be able to get away with LSI
2019-03-07T01:56:36 < catphish> timekeeping seems unnecessary
2019-03-07T01:56:37 < zyp> IIRC it has a second LSI that's more accurate than the old shitty LSI that were wildly inaccurate
2019-03-07T01:56:56 < zyp> not if you need to wake up at particular intervals
2019-03-07T01:57:36 < catphish> no ethernet?
2019-03-07T01:58:06 < zyp> nah, for a stm32 it's fairly small
2019-03-07T01:58:18 < zyp> got usb though

2019-03-07T03:28:06 < arc_phasor> i thought i could just call HAL_GPIO_ReadPin to change it to a high-z input, but no dice, stays driving the output

2019-03-07T03:57:36 < rajkosto> I2C NOT WORK HELP
2019-03-07T04:03:04 < englishman> wtf he left
2019-03-07T04:03:07 < rajkosto> im an idiot i2c work
2019-03-07T04:10:50 < rajkosto> there's a 25.68uS set of SDA and SCL to 0 when i do init of the gpio tho
2019-03-07T04:15:26 < rajkosto> how do i prevent that
2019-03-07T04:19:00 < englishman> pullups?
2019-03-07T04:20:41 < rajkosto> theyre there
2019-03-07T04:20:48 < rajkosto> the stm32 is actively driving them both to 0
2019-03-07T04:21:37 < rajkosto> https://pastebin.com/K3kPnakb doesnt really matter if i do the AFIO before or after the i2c init
2019-03-07T04:23:42 < dongs> is that I2C on APB1
2019-03-07T04:24:33 < dongs> rajkosto: there's also *_StructInit() calls to clean up structs before going to *_Init() calls, just to be safe there's no junk
2019-03-07T04:24:45 < dongs> like I2C_StructInit(&i2c) first before filling it
2019-03-07T04:25:33 < rajkosto> yeah they are on apb1 or the whole thing wouldnt work
2019-03-07T04:25:40 < rajkosto> theres no need to call structinit when im setting ALL the fields
2019-03-07T04:25:52 < dongs> sure, just saying

2019-03-07T04:26:09 < dongs> this is F1 right?
2019-03-07T04:26:15 < dongs> are you on the I2C pins that don't need remapping?
2019-03-07T04:26:30 < dongs> see y ou hided all the shit befhind #defines so i can't tell
2019-03-07T04:26:33 < rajkosto> im on i2c2, b10 and b11
2019-03-07T04:26:34 < dongs> PB6/PB7 is it?
2019-03-07T04:26:45 < dongs> ok and thats default remap for it?
2019-03-07T04:27:01 < rajkosto> no idea but its working https://images.sshnuke.net/2019-03-07_03-26-57_NmnQracKF.png
2019-03-07T04:27:15 < dongs> so what part isnt working
2019-03-07T04:27:24 < rajkosto> i dont want the set to 0
2019-03-07T04:27:26 < rajkosto> on the init
2019-03-07T04:28:55 < rajkosto> i even did this before any i2c init so that there's a 1 in the gpio register just in case https://pastebin.com/FwyNByTM
2019-03-07T04:38:54 < dongs> is your slave stuck
2019-03-07T04:39:00 < dongs> when you init i2c are both scl/sda at high?
2019-03-07T04:39:11 < dongs> looks liek clk is stuck after last pulse
2019-03-07T04:39:16 < dongs> in your pic
2019-03-07T04:39:47 < dongs> i would do the i2c clockout thing before initing peripheral just to make sure nothing is stuck from prebvious debug session
2019-03-07T04:41:44 < rajkosto> when i init it its all high yes
2019-03-07T04:44:12 < rajkosto> dont mind the SCL being stuck low, its cuz i forgot to generate stop on error
2019-03-07T05:06:17 < rajkosto> wtf does the i2c busy flag not clear until you generate stop bit or something ?
2019-03-07T05:07:57 < dongs> F103 i2c is pretty well busted
2019-03-07T05:07:59 < rajkosto> i need to detect case of when all the bits have been clocked out but the slave didnt ack address
2019-03-07T05:18:00 < rajkosto> fuck it https://images.sshnuke.net/2019-03-07_04-17-40_NEwJ7P8Y6.png https://images.sshnuke.net/2019-03-07_04-17-55_Jnu77jCat.png
2019-03-07T05:19:56 < Ultrasauce> a macro with a conditional return statement in it
2019-03-07T05:23:55 < rajkosto> wouldnt need to be a macro if hte return wasnt in it
2019-03-07T05:23:57 < rajkosto> would just be inline func

2019-03-07T05:55:02 < dongs> using cpu clock cycles to timeotu I2C sounds like such a wonderful idea
2019-03-07T05:55:11 < rajkosto> EMPIRICALLY
2019-03-07T05:55:12 < rajkosto> PROVEN
2019-03-07T05:56:38 < rajkosto> i tried doing it right and something like this should have worked https://images.sshnuke.net/2019-03-07_04-56-29_0Z4H5mi0d.png
2019-03-07T05:56:57 < rajkosto> busy never gets cleared tho
2019-03-07T05:57:15 < rajkosto> need a bit that gets cleared when everything got clocked out on the bus (this IS BUSY for SPI and UART)
2019-03-07T05:57:28 < dongs> 72mhz is not fast enough to process some I2C stuff
2019-03-07T05:57:34 < rajkosto> 96*
2019-03-07T05:57:40 < dongs> ive never used polling I2C on F1
2019-03-07T05:57:44 < dongs> it never worked right
2019-03-07T05:57:45 < dongs> had to do IRQs
2019-03-07T05:57:52 < dongs> that or just bitbang that shit
2019-03-07T05:57:55 < rajkosto> this is a master
2019-03-07T05:57:58 < dongs> yes
2019-03-07T05:57:59 < rajkosto> so nothing happens unless i progress it
2019-03-07T05:58:02 < dongs> no
2019-03-07T05:58:04 < dongs> incorrect
2019-03-07T05:58:05 < rajkosto> so why would cpu freq matter
2019-03-07T05:58:11 < dongs> if you don't checkstatus/something on time, it will lock up
2019-03-07T05:58:15 < dongs> its in errata
2019-03-07T05:58:21 < dongs> yes master
2019-03-07T05:58:23 < rajkosto> fuck this gay earth
2019-03-07T05:58:36 < dongs> nobody fucking uses i2c slave on on stm
2019-03-07T06:06:15 < rajkosto> well this cant lock up it has all the timeouts 
2019-03-07T06:06:36 < rajkosto> if the errata happens it will just end the transaction with an error

2019-03-07T09:58:44 < jpa-> zyp: for the record, this is what i ended up with: http://paste.dy.fi/phU/plain   it doubles the speed of the loop compared to the gcc + intrinsics version; but that's still just 10% speedup in the complete algorithm
2019-03-07T09:59:50 < jpa-> it might be possible to go lambda += 2 in the loop and then just check odd offsets after loop
2019-03-07T10:01:26 < jadew> kakimir, you might be able to ask the compiler to spit that info out and then embed it in your program
2019-03-07T10:01:32 < jadew> sort of like a two-step thing
2019-03-07T10:01:44 < jadew> a build step for the resources
2019-03-07T10:03:29 < jadew> you could then use RTTI to identify the type and match it with the more complete type information
2019-03-07T10:03:43 < jpa-> you can also play tricks with xmacros
2019-03-07T10:04:17 < zyp> jpa-, by the way, can't you reorder the operations to eliminate some loads?
2019-03-07T10:05:19 < zyp> instead of foreach(lambda) foreach(weight), can't you do something like foreach(weight) foreach(lambda) so you only have to load each weight once?
2019-03-07T10:05:29 < jpa-> zyp: yeah, i thought about computing two offsets in a single inner loop with single set of loads; but then it's difficult to use smlad because i'd have to kind of shift everything by a halfword
2019-03-07T10:05:58 < jpa-> ah that also, but then i'd still have to load and store L_result for each lambda

2019-03-07T10:29:03 < jpa-> 2 at a time, and you can mux as many as you have mux inputs
2019-03-07T10:29:37 < crispy> ok so if i got a TriggerMux with 1x73
2019-03-07T10:30:17 < crispy> i can handle 2x73 in general, but only 2 at a time?
2019-03-07T10:34:05 < jpa-> what's a triggermux?
2019-03-07T10:34:24 < jpa-> that sounds something that would just select what signal triggers the conversion
2019-03-07T10:34:34 < jpa-> instead of selecting input source

2019-03-07T11:06:10 < zyp> to be fair, I suppose it inlines and folds the ssat function before it starts looking for the ssat pattern, and after it's folded it's probably not recognizable anymore
2019-03-07T11:06:21 < jpa-> yeah
2019-03-07T11:08:39 < zyp> but, uh, what do you mean no speed penalty?
2019-03-07T11:09:21 < jpa-> isn't cmp + ite block basically 1 cycle also, like ssat would be?
2019-03-07T11:09:36 < jpa-> the movw r3, #32767 would be lifted outside any inner loop
2019-03-07T11:10:24 < zyp> ah, yeah, if you get the movw out of the inner loop, it should be the same

2019-03-07T11:24:50 < zyp> ST seems to have put in quite some effort to lock down CPU2 on STM32WB
2019-03-07T11:25:56 < jpa-> probably to satisfy all those FCC / CE requirements of not allowing modifying radio firmware?
2019-03-07T11:27:10 < zyp> that's my guess too, but still
2019-03-07T11:28:57 < zyp> I find it funny how ST changed the wording in the RM between the prerelease I got and the released revision
2019-03-07T11:29:21 < zyp> rev2: A flag (ESE) is available from the Flash memory option register (FLASH_OPTR) informing if CPU2 security is enabled.
2019-03-07T11:29:26 < zyp> rev4: A flag (ESE) is available from the Flash memory option register (FLASH_OPTR) informing that CPU2 security is enabled.
2019-03-07T11:33:12 < Steffanx> Hmm lock down in what way zyp? Cant easily use it yourself? As in remove RF stuff and use it for something else?
2019-03-07T11:37:51 < karlp> dongs: red, "nobody fucking uses i2c slave on on stm" jpa is doing it for 200€ flat fee :)
2019-03-07T11:39:14 < zyp> Steffanx, well, according to rev4, parts will ship with the security mode enabled and doesn't say anymore how to disable it
2019-03-07T11:40:42 < zyp> the bits that controls it are only writable by CPU2 when the security mode is enabled
2019-03-07T11:43:43 < zyp> although, according to rev2 there at least used to be a way to do a full erase including a security mode disabling, but I don't know if that method still works on production parts
2019-03-07T11:45:51 < zyp> I wonder if that still works, and if it still works, I wonder if it'll also delete the keys the bootloader uses to decrypt the radio firmware, making it impossible to load the encrypted firmwares anymore

2019-03-07T19:45:35 < mawk> little endian is everywhere but networking
2019-03-07T19:50:58 < PaulFertser> Some ARMs can run in BE, MIPS often runs in BE.

2019-03-07T22:31:38 < Ecco> Hi :)
2019-03-07T22:31:52 < Ecco> I'd like to power a PCB with 5V
2019-03-07T22:32:04 < Ecco> I thought about using a micro-usb PSU
2019-03-07T22:32:24 < Ecco> but I'm afraid it won't play well with "high" power (2 or 3A)
2019-03-07T22:32:34 < Ecco> What connector would you guys recommend?
2019-03-07T22:32:53 < Ecco> I've been browsing aliexpress to try and find a "standard" connector (appart from micro-usb)
2019-03-07T22:33:13 < Ecco> and there's quite a lot of jack power adapter
2019-03-07T22:33:24 < srk> barrel jack
2019-03-07T22:33:28 < Ecco> yeah
2019-03-07T22:33:29 < srk> heh, yeah
2019-03-07T22:33:33 < Ecco> but what about the size
2019-03-07T22:33:34 < qyx> usually 2.1/5.5mm barrel jacks are used
2019-03-07T22:33:37 < srk> ^^
2019-03-07T22:33:39 < Ecco> is there a "standard" one?
2019-03-07T22:33:44 < srk> ty qyx 
2019-03-07T22:33:50 < qyx> np srk 
2019-03-07T22:33:54 < Ecco> thanks
2019-03-07T22:34:04 < Ecco> I'm kind of curious though because the sellers on Ali don't even mention the size of the jack
2019-03-07T22:34:12 < qyx> either choose the cheap ones from china
2019-03-07T22:34:15 < srk> was buying these week ago but couldn't remember :|
2019-03-07T22:34:19 < qyx> or some serious for higher currents
2019-03-07T22:34:22 < kakimir> usb type B
2019-03-07T22:34:34 < qyx> usb B is not for 3 amps
2019-03-07T22:34:46 < Ecco> Well, I'll more likely pull ~1A
2019-03-07T22:34:51 < Ecco> But I'd rather size the thing for 3A
2019-03-07T22:34:57 < kakimir> but certainly you can put 3amp thru it
2019-03-07T22:34:58 < Ecco> so that gives me a margin
2019-03-07T22:35:00 < kakimir> no problemos
2019-03-07T22:35:15 < qyx> Ecco: https://en.globtek.com/images/high-current-coaxial-barrel-plug-jacks-for-high-wattage-power-supplies/r5.jpg
2019-03-07T22:35:18 < qyx> such thing
2019-03-07T22:35:36 < kakimir> that is 5.5 x 2.5 right?
2019-03-07T22:35:37 < Ecco> yeah ok :)
2019-03-07T22:35:42 < qyx> depends
2019-03-07T22:35:48 < qyx> I would not select 2.5 inner
2019-03-07T22:35:54 < qyx> because it limits your optiuons then
2019-03-07T22:36:05 < Ecco> so 2.1 x 5.5, is that the most common?
2019-03-07T22:37:00 < Ecco> Ha, ok, my bad, the jack size was mentionned in the Ali one I was looking at
2019-03-07T22:37:08 < Ecco> as a matter of fact, this one is 5.5x2.5
2019-03-07T22:37:10 < Ecco> https://www.aliexpress.com/item/Power-Adapter-DC-5V-9V-12V-24V-1A-2A-3A-Adaptor-220V-To-5-V-12/32898167936.html
2019-03-07T22:37:36 < Ecco> Would a cheap chinese 3A psu do a decent job or is that utter crap?
2019-03-07T22:37:53 < Ecco> Like I said, it'll most likely draw 2A at most
2019-03-07T22:38:00 < Ecco> (it = my pcb)
2019-03-07T22:38:39 < qyx> if I designed a device drawing ~10W, I would make it wide input range
2019-03-07T22:38:48 < srk> I would avoid chinese PSUs
2019-03-07T22:39:03 < kakimir> do you have margin for cable/contact losses?
2019-03-07T22:39:11 < srk> seen a few with sparkling cables, much safe
2019-03-07T22:39:11 < qyx> something like 5-28 V or so
2019-03-07T22:39:36 < rajkosto> innovators, when we all switching to usb-c
2019-03-07T22:39:42 < Ecco> qyx: why?
2019-03-07T22:39:57 < qyx> because voltage drop
2019-03-07T22:40:08 < qyx> as kakimir says
2019-03-07T22:40:11 < Ecco> kakimir: well, yeah, it'll just reboot the system
2019-03-07T22:40:19 < qyx> mhm also the high current ones are actually 2.5/5.5mm
2019-03-07T22:40:32 < kakimir> what will reboot what
2019-03-07T22:40:40 < Ecco>  kakimir> do you have margin for cable/contact losses?
2019-03-07T22:40:46 < Ecco> -> if contact is lost, it'll reboot my PCB
2019-03-07T22:41:46 < kakimir> so you want robbust contact?
2019-03-07T22:41:53 < Ecco> well, yes
2019-03-07T22:42:29 < Ecco> as much as possible :)
2019-03-07T22:45:31 < kakimir> I use powerpole and amass xt series for everything
2019-03-07T22:47:10 < Ecco> ok
2019-03-07T22:47:24 < Ecco> but then, how do you find a PSU with an XT connector?
2019-03-07T22:47:34 < kakimir> I don't
2019-03-07T22:47:44 < kakimir> I make the lead myself
2019-03-07T22:47:50 < Ecco> hmm
2019-03-07T22:49:11 < Ecco> My PCB needs to power a 5V part
2019-03-07T22:49:24 < Ecco> if I pick anything higher, I'll need a DC-DC converter
2019-03-07T22:49:32 < Ecco> would an LDO do the job?
2019-03-07T22:49:40 < Ecco> this for instance : https://www.st.com/resource/en/datasheet/ld29300.pdf
2019-03-07T22:49:48 < Ecco> If I feed it 12V at 3A
2019-03-07T22:49:57 < Ecco> it would have to dissipate a ton of power
2019-03-07T22:50:06 < qyx> thats not going to work
2019-03-07T22:50:17 < qyx> 7*3W is too much
2019-03-07T22:50:21 < Ecco> yeah
2019-03-07T22:50:25 < kakimir> Ecco: can you explain the problem more
2019-03-07T22:50:35 < Ecco> well, the problem is actually very simple
2019-03-07T22:50:58 < Ecco> I have a PCB that needs 5V at 3A (to be safe. more realistically 5V at 2A max)
2019-03-07T22:51:13 < Ecco> question: how do I power that thing from a wall outlet?
2019-03-07T22:51:33 < kakimir> with usb phone charger certainly
2019-03-07T22:51:38 < kakimir> a good one
2019-03-07T22:51:52 < Ecco> well, yeah, that's what I did so far
2019-03-07T22:51:54 < Ecco> it works
2019-03-07T22:52:01 < Ecco> but the micro-usb plug is a bit flimsy
2019-03-07T22:52:28 < kakimir> do you need a connection or can you solder gnd and vbus directly to the board from usb lead?
2019-03-07T22:52:45 < kakimir> what are the practicality aspects
2019-03-07T22:52:58 < Ecco> Well, really, I can decide
2019-03-07T22:53:13 < Ecco> being able to plug/unplug is always nice because you can easily swap'n'replace
2019-03-07T22:53:35 < Ecco> (if the PSU gets fried for some reason)
2019-03-07T22:53:51 < Ecco> I definitely could just cut the wire open and solder it on the PCB
2019-03-07T22:54:07 < Ecco> it's just that I kinda liked the conveniency of being able to change the psu if needed
2019-03-07T22:54:18 < zyp> for 5V 2A microusb is the obvious choice, everything is using it nowadays
2019-03-07T22:54:33 < Ecco> well, that's the choice I made so far
2019-03-07T22:54:39 < zyp> you could also go usb-c if you prefer, but micro is still more common
2019-03-07T22:54:44 < kakimir> certainly
2019-03-07T22:55:03 < Ecco> but the micro-usb traces/pads/pins are so thin
2019-03-07T22:55:19 < zyp> what problems have you had with microusb?
2019-03-07T22:55:29 < Ecco> I'm being concerned about voltage drop and the circuit overheating
2019-03-07T22:55:30 < kakimir> in microusb the most concern is about connection to the pcb
2019-03-07T22:55:38 < kakimir> and shitty cables
2019-03-07T22:55:44 < Ecco> yeah, that too
2019-03-07T22:56:12 < zyp> I don't have an impression that heat is a major issue
2019-03-07T22:56:27 < zyp> shitty cables are, but that's solved by not buying shitty cables
2019-03-07T22:56:46 < kakimir> mechanical stress if the connector is SMT type
2019-03-07T22:56:49 < zyp> mechanical rigidity might be another issue if you don't get a decent socket in a fitting footprint
2019-03-07T22:57:15 < zyp> but just get it right and it's not a big issue
2019-03-07T22:58:21 < Ecco> Allright
2019-03-07T22:58:42 < Ecco> I just thought that a big-ol-jack would be somehow a better solution: sturdier, lower resistance
2019-03-07T22:59:06 < Ecco> lol, Tim Cook changed his name to Tim Apple on Twitter :-D
2019-03-07T22:59:21 < zyp> better is relative, you need to figure out your priorities before you can compare
2019-03-07T22:59:44 < Ecco> He might not be that uptight, after all ^^
2019-03-07T22:59:48 < kakimir> if the thing is like doing resets and stuff
2019-03-07T22:59:53 < Ecco> no it's not
2019-03-07T23:00:00 < kakimir> you are just having too little bypass capacitance
2019-03-07T23:00:14 < Ecco> reason #1 I'm looking forward to change: one of the thing the PCB powers is a raspberry-pi
2019-03-07T23:00:19 < zyp> big old jack might be tougher, but nobody has shit that just plugs into that
2019-03-07T23:00:24 < Ecco> and the raspberry-pi has an indicator for voltage drops
2019-03-07T23:00:36 < Ecco> and in the current scheme, this indicators happens to turn on quite often
2019-03-07T23:00:55 < Ecco> zyp: oh, I provide the PSU too
2019-03-07T23:00:59 < zyp> you could have considered the full size usb-b connector if you want a big sturdy thing, but that's not gonna work in practice
2019-03-07T23:01:11 < Ecco> why not?
2019-03-07T23:01:22 < Ecco> again, because no one has a usb-b psu lying around?
2019-03-07T23:01:35 < zyp> because no devices are charging through that plug, so good luck finding cables designed for more than 500mA
2019-03-07T23:01:38 < Ecco> (I didn't even know these were a thing)
2019-03-07T23:01:45 < Ecco> yeah
2019-03-07T23:01:45 < rajkosto> Ecco, the traces for microusb are not that thing, and its going to be on the pcb anyway, after the footprint you can fatten them up
2019-03-07T23:01:53 < zyp> miniusb have the same problem
2019-03-07T23:02:04 < rajkosto> thin*
2019-03-07T23:02:05 < Ecco> well, the easiest option is to just put both
2019-03-07T23:02:10 < zyp> ran into it when I got one of dongs' ipad adapter boards
2019-03-07T23:02:15 < Ecco> I can put both a 2.5mm jack *and* a microusb
2019-03-07T23:02:40 < zyp> fucking impossible to find a miniusb cable that doesn't drop too much voltage to be usable
2019-03-07T23:02:53 < zyp> ended up using a microusb cable and a micro to mini adapter
2019-03-07T23:03:17 < Ecco> yeah, by the way
2019-03-07T23:03:20 < Ecco> how do those even work?
2019-03-07T23:03:27 < zyp> those what?
2019-03-07T23:03:28 < Ecco> I mean a standard 5V jack PSU
2019-03-07T23:03:45 < Ecco> Where is the 5V, exactly?
2019-03-07T23:03:53 < Ecco> At the jack or within the PSU?
2019-03-07T23:04:06 < zyp> at the PSU, naturally
2019-03-07T23:04:13 < Ecco> Do they have like a third probe wire that goes back so the PSU can adjust?
2019-03-07T23:04:16 < zyp> otherwise it'd need a sense wire back through the cable
2019-03-07T23:04:23 < Ecco> yeah
2019-03-07T23:04:23 < zyp> like ATX PSUs got
2019-03-07T23:04:37 < Ecco> heh
2019-03-07T23:04:38 < Ecco> wait a minute
2019-03-07T23:04:57 < Ecco> well, those are a bit expensive
2019-03-07T23:05:03 < Ecco> but it wouldn't be that dumb actually
2019-03-07T23:05:13 < zyp> wouldn't be what?
2019-03-07T23:05:20 < Ecco> use an ATX PSU
2019-03-07T23:05:25 < Ecco> completely overkill
2019-03-07T23:05:27 < zyp> uh
2019-03-07T23:05:44 < zyp> you're talking over an order of magnitude more power
2019-03-07T23:05:47 < rajkosto> just use microusb like a normal person
2019-03-07T23:05:51 < Ecco> :-D
2019-03-07T23:05:52 < zyp> yeah
2019-03-07T23:05:54 < Ecco> Yeah
2019-03-07T23:05:55 < Ecco> https://www.aliexpress.com/item/Power-Adapter-DC-5V-9V-12V-24V-1A-2A-3A-Adaptor-220V-To-5-V-12/32898167936.html
2019-03-07T23:05:58 < Ecco> Look at those things
2019-03-07T23:06:09 < Ecco> The cable looks decently big
2019-03-07T23:06:15 < Ecco> assuming the copper inside is not hair-thin
2019-03-07T23:06:22 < rajkosto> those are usually pretty crap
2019-03-07T23:06:29 < Ecco> what voltage drop should one expect?
2019-03-07T23:06:43 < zyp> anyway, if you need 5V 2A, use microusb if you care about easily available supplies, use usb-c if you want an improved but so far less common alternative
2019-03-07T23:07:05 < Ecco> makes sense
2019-03-07T23:07:18 < zyp> if you supply a supply with your device, I'd say that's an argument to use usb-c over microusb
2019-03-07T23:07:26 < zyp> since availability matters less
2019-03-07T23:07:34 < englishman> bc1.2 is so dumb
2019-03-07T23:07:35 < Ecco> indeed
2019-03-07T23:07:36 < rajkosto> makes your device more expensive
2019-03-07T23:07:46 < zyp> nah
2019-03-07T23:07:48 < englishman> pd is quite complex we will have to wait much longer than 8 years for it to be ubiquitous
2019-03-07T23:08:03 < rajkosto> quickcharge ;)
2019-03-07T23:08:09 < englishman> proprietarycharge
2019-03-07T23:08:13 < rajkosto> normal microusb cables work for it
2019-03-07T23:08:21 < rajkosto> and you can get chinese QC buck converters
2019-03-07T23:08:26 < englishman> which simple TI chips support QC again?
2019-03-07T23:08:29 < qyx> you can still fit it with a euro socket for ~230V
2019-03-07T23:08:33 < zyp> the only practical difference between putting a microusb socket and a usb-c socket is that you need two pulldown resistors as well
2019-03-07T23:09:04 < rajkosto> usb-c is usually mid-mount, has way more pins, and requires some extra components/routing
2019-03-07T23:09:07 < qyx> esp32 has secure boot
2019-03-07T23:09:11 < qyx> englishman: you were right
2019-03-07T23:09:19 < englishman> hehe
2019-03-07T23:09:20 < zyp> gnd/vbus and data lines hook up the same, apart from those you only need a pulldown on each CC line
2019-03-07T23:09:22 < qyx> esp32 >>>> stm32, the best mcu on the planet
2019-03-07T23:09:25 < englishman> truth
2019-03-07T23:09:37 < rajkosto> zyp, dont you need a controller on CC
2019-03-07T23:09:42 < rajkosto> to negotiate the higher voltages
2019-03-07T23:09:48 < englishman> and esp-wroom-32 the best module on the planet
2019-03-07T23:09:59 < zyp> rajkosto, nobody said anything about negotiating higher voltages
2019-03-07T23:10:19 < qyx> but I am kinda disappointed by the way it is designed to work
2019-03-07T23:10:19 < rajkosto> thats what the quickcharge ICs let me do

2019-03-07T23:10:54 < qyx> you don't have full control of the mcu
2019-03-07T23:10:54 < zyp> when substituting usb-c for microusb without adding any features, all you need on the CC lines are pulldown resistors to tell the other end you are a device/sink
2019-03-07T23:11:10 < rajkosto> what about SUPERSPEED
2019-03-07T23:11:19 < rajkosto> need a mux chip for that
2019-03-07T23:11:24 < zyp> if you want more features that you couldn't have on microusb, sure that's more complexity
2019-03-07T23:11:34 < rajkosto> microusb 3.0 ;)
2019-03-07T23:11:40 < rajkosto> best connector
2019-03-07T23:12:10 < zyp> also, if you can afford a usb3 chip, you can also afford a mux for the SS lanes :p
2019-03-07T23:12:35 < rajkosto> nah
2019-03-07T23:12:38 < rajkosto> the FTDI ones are pretty cheap
2019-03-07T23:13:03 < zyp> englishman, I disagree, PD sources seems to be fairly ubiquitous already
2019-03-07T23:13:17 < englishman> maybe in the typical millenial household
2019-03-07T23:14:13 < zyp> idk
2019-03-07T23:14:23 < zyp> just saying, my phone charger has PD
2019-03-07T23:14:45 < englishman> sure
2019-03-07T23:14:50 < zyp> had it for two-three years, never used the PD function though
2019-03-07T23:14:54 < englishman> but i'm making a thing that also has to charge from a computer
2019-03-07T23:14:58 < englishman> so it has to support both
2019-03-07T23:15:23 < zyp> should be easy enough
2019-03-07T23:15:52 < zyp> make it support PD, if it doesn't detect a PD source, just regulate by vbus voltage according to BC
2019-03-07T23:15:58 < englishman> yeah
2019-03-07T23:16:00 < englishman> so far
2019-03-07T23:16:04 < rajkosto> my QuickCharge charger was cheaper and has same stuff while being microusb
2019-03-07T23:16:06 < englishman> 2 ICs plus a MCU
2019-03-07T23:16:11 < englishman> just to charge over USB
2019-03-07T23:16:36 < zyp> haha, why?
2019-03-07T23:17:03 < englishman> one PD negotiator, one battery charger, and MCU to manage
2019-03-07T23:17:48 < englishman> a TI rep has some solutions for me but the chargers they make that fully support PD don't do BC1.2 fully
2019-03-07T23:18:02 < zyp> I mean, battery charger you need anyway
2019-03-07T23:18:12 < mawk> PD means pederast, right ?
2019-03-07T23:18:17 < zyp> yes
2019-03-07T23:18:19 < englishman> only to pedo image hosters
2019-03-07T23:18:22 < mawk> :(
2019-03-07T23:18:26 < rajkosto> i dont know how long they will be supported, but i love the quickcharge input bucks
2019-03-07T23:18:36 < mawk> I'm no pedo, that's calomny englishman 
2019-03-07T23:18:39 < mawk> I defy you in a duel
2019-03-07T23:18:41 < rajkosto> chinese cloning tech at its best
2019-03-07T23:18:48 < mawk> put on your white gloves
2019-03-07T23:19:12 < englishman> BC1.2 is weird anyway. it defines the supply side as allowing up to 5A but the periph is only allowed to draw 1.5A
2019-03-07T23:19:49 < zyp> as far as I can tell nobody cares about the 1.5A limit
2019-03-07T23:20:01 < englishman> yeah, until you find that one computer that does care :(
2019-03-07T23:20:26 < englishman> anyway, all of TI's last generation stuff does exactly that, vbus monitoring while incrementing charge current
2019-03-07T23:20:29 < englishman> in the battery charger IC
2019-03-07T23:20:35 < englishman> in the PD generation they lose that for some reason
2019-03-07T23:20:56 < englishman> plus the ICs are much much more complex
2019-03-07T23:20:56 < zyp> probably because they are designed for different power levels
2019-03-07T23:21:08 < englishman> this PD controller has 3 i2c interfaces
2019-03-07T23:21:24 < englishman> different power yes, but currents are the same
2019-03-07T23:21:57 < zyp> I mean, BC was designed to charge phones, PD was designed to charge laptops
2019-03-07T23:22:24 < englishman> that's a problem, when you want to charge a phone :(
2019-03-07T23:22:58 < zyp> what max charge power are you targetting?
2019-03-07T23:23:10 < englishman> 25W or so
2019-03-07T23:23:28 < zyp> okay, that's in the PD range
2019-03-07T23:23:33 < englishman> yeah
2019-03-07T23:23:41 < englishman> from legacy USB, as much as possible
2019-03-07T23:23:54 < englishman> it still needs to charge when plugged into a computer, and not at 2.5W
2019-03-07T23:24:01 < zyp> I mean, phones now aren't the same as phones was when BC were written :p
2019-03-07T23:24:17 < zyp> but ok
2019-03-07T23:24:58 < zyp> you want something that can work with all sorts of legacy solutions, naturally then you need to add support for them all :p
2019-03-07T23:25:13 < englishman> yes, and there are a bunch of drop in ICs that do that
2019-03-07T23:25:18 < englishman> but then adding PD becomes harder
2019-03-07T23:25:36 < englishman> anyway the TI guy gave me some stuff and he should get back to me tomorrow
2019-03-07T23:25:58 < zyp> hmm, let's see here
2019-03-07T23:27:26 < zyp> by the way, will the usb port be used for anything but powering?
2019-03-07T23:27:36 < englishman> yes, but just usb2 device
2019-03-07T23:27:51 < zyp> hmm
2019-03-07T23:28:39 < zyp> what's the device? some cortex-a chip or a mcu?
2019-03-07T23:29:58 < englishman> big cortex-a and display and other stuff
2019-03-07T23:30:03 < englishman> like 6-8W total i think

2019-03-07T23:50:04 < aandrew> between quirky slaves fucking with clock hold and other general i2c goofiness I would not ever design a multimaster i2c system
2019-03-07T23:50:21 < rajkosto> some device datasheets specifically require repeated start in order to do some operations
2019-03-07T23:51:34 < Cracki> if you try it without (instead with explicit stop+start+addressing the slave again), you might discover that it still works... or it might not :P
2019-03-07T23:51:39 < rajkosto> it didnt
2019-03-07T23:51:43 < Cracki> good
2019-03-07T23:51:57 < rajkosto> and whatever mcu i was on didnt support repeated start so i had to bitbang it lol

2019-03-07T23:52:43 < Cracki> it's just open drain anyway :>
2019-03-07T23:58:57 < rajkosto> you also have to follow the proper ACK/NACK protocol when receiving bytes otherwise the slave can try and drive the bus after you want to release it
2019-03-07T23:59:09 < rajkosto> i made that mistake of acking even the last byte when the slave used the ack for "dont send any more bytes"
2019-03-07T23:59:23 < rajkosto> so slave was driving bus after master tried to STOP
--- Day changed Fri Mar 08 2019
2019-03-08T00:08:31 < rajkosto> also i realise now why stm32f103 designs use a transistor to enable the 1.5k USB_DP pullup, because if you dont, then while the device is in reset you will get enumeration error

2019-03-08T10:40:29 < Cracki> and when the PC crashes that drives the five figures stratasys, they'll reattempt the print same day *next* week because they only open one day a week to the public
2019-03-08T10:40:54 < Cracki> I don't know what glue they huff but they act like it
2019-03-08T10:41:34 < Cracki> either that or they're bored out of their minds by their job
2019-03-08T10:41:57 < Cracki> if I had all the toys they do, I would do so much stuff

2019-03-08T11:00:35 < Cracki> I'm looking for a combo of motor shaft diameter and encoder code disc bore diameter...
2019-03-08T11:00:53 < Cracki> mabuchis seem to come in ~2.3mm, those cheap code wheels come in ~4mm
2019-03-08T11:01:25 < Cracki> also the sensor I'm considering wants optical center at 11mm radius, but those code wheels are made for ~9mm and might not even have lines at 11mm
2019-03-08T11:08:28 < rajkosto> 2 floats of this sensor's output are always 0.000 why
2019-03-08T11:14:45 < rajkosto> i feel like ive been lied to
2019-03-08T11:15:09 < kakimir> I got weird email
2019-03-08T11:15:24 < kakimir> to personal email
2019-03-08T11:15:58 < kakimir> somebody from pcbway asked me how are projects
2019-03-08T11:16:28 < Cracki> are they shaking their customers for "maybe"-projects?
2019-03-08T11:16:33 < Cracki> rajkosto, wat sensor
2019-03-08T11:16:38 < rajkosto> AS7261
2019-03-08T11:16:48 < rajkosto> CCT and LUX are always 0.000 everything else is wiggling
2019-03-08T11:16:57 < kakimir> that is how I understood it Cracki 
2019-03-08T11:17:11 < Cracki> maybe needs init for those?
2019-03-08T11:17:39 < rajkosto> nothing to init
2019-03-08T11:17:40 < Cracki> or saturated?
2019-03-08T11:17:49 < rajkosto> maybe it needs way higher integration time set
2019-03-08T11:17:54 < Cracki> or that
2019-03-08T11:18:04 < rajkosto> its already so slow at 100ms for one (it does 2 for all the values)
2019-03-08T11:18:12 < kakimir> I certainly do appreciate reminding of my personal project
2019-03-08T11:18:18 < kakimir> somebody finally cares
2019-03-08T11:19:27 < Cracki> maybe it's saturated.
2019-03-08T11:19:48 < Cracki> or fuck with gain
2019-03-08T11:19:57 < rajkosto> MAXIMUM GAIN
2019-03-08T11:20:01 < Cracki> or don't work in a dark cave

2019-03-08T11:20:08 < Cracki> yeah maybe it's saturated
2019-03-08T11:20:22 < rajkosto> nah even with 64x gain the values are way lower than max 65535

2019-03-08T14:44:17 < qyx> for example
2019-03-08T14:44:32 < jpa-> yeah, stuff like standby power draw etc are useless, esp32 is great and needs no specs
2019-03-08T14:44:37 < qyx> and such weird things
2019-03-08T14:45:06 < qyx> the low power coprocessor is some FSM with assembly language

2019-03-08T16:27:52 < jadew> Haohmaru, well, for example, now I'm unable to calibrate my sig gen because the adapter between the generator's output connector and the power sensor becomes a band stop filter at random frequencies, depending on how you breathe
2019-03-08T16:28:13 < BrainDamage> make sure you get a torque wrench too
2019-03-08T16:28:24 < BrainDamage> at those freqs, you want reliabile mating
2019-03-08T16:28:26 < jadew> yeah, I've been getting by without one
2019-03-08T16:28:30 < jadew> yup
2019-03-08T16:29:15 < BrainDamage> 1mm or more or less will be ~10% signal change

2019-03-08T16:33:40 < jadew> I kinda wonder what's the secret for the high-end adapters
2019-03-08T16:34:10 < BrainDamage> precise machining and exotic materials
2019-03-08T16:34:10 < jadew> and why aren't they making only high quality ones
2019-03-08T16:34:26 < jadew> ah, so it's something extra
2019-03-08T16:34:41 < BrainDamage> eg teflon is too lossy past 12GHz
2019-03-08T16:34:43 < jadew> it's not just... we can make them either way, but we cripple these ones so you pay more for the others
2019-03-08T16:34:57 < jadew> what are they using instead?
2019-03-08T16:35:17 < BrainDamage> never looked past 10GHz
2019-03-08T16:35:30 < jadew> seems it's still teflon
2019-03-08T16:36:43 < BrainDamage> you still need the high machining precision, they'd have to be milled, not just casted
2019-03-08T16:38:38 < jadew> BrainDamage, I thought most of them are machined anyway
2019-03-08T16:40:12 < jadew> at least most connectors past $10 seem to be machined

2019-03-08T16:47:42 < kakimir> you think the song is the shit
2019-03-08T16:47:48 < kakimir> until next song comes along
2019-03-08T16:48:16 < kakimir> autoplay is for music adventure
2019-03-08T16:48:47 < jadew> BrainDamage, for 11 GHz it seems I can get away with just $10 - $12 per connector
2019-03-08T16:49:11 < BrainDamage> jadew: yup, that's still within the range of "normal" connectors
2019-03-08T16:49:17 < BrainDamage> just not china cheapshit
2019-03-08T16:49:18 < jadew> think the performance will degrade a lot from 11 to 20?
2019-03-08T16:50:18 < BrainDamage> depends on your precision requirements
2019-03-08T16:50:32 < BrainDamage> but I'd espect 10dB loss at least
2019-03-08T16:50:37 < jadew> ah
2019-03-08T16:50:40 < jadew> that's crap
2019-03-08T16:50:46 < BrainDamage> if you only need a qualititative measurement it should be ok
2019-03-08T16:50:57 < BrainDamage> like a filter's freq response
2019-03-08T16:51:12 < BrainDamage> but if you need quantitative like return loss peak, etc, then no
2019-03-08T16:51:39 < jadew> got it, thanks
2019-03-08T16:51:52 < BrainDamage> I have a bunch of standard semirigid cables 
2019-03-08T16:51:57 < BrainDamage> I call them 1dB cables
2019-03-08T16:52:08 < BrainDamage> connector + cable + connector loss at 10GHz is 1dB
2019-03-08T16:52:23 < BrainDamage> makes for pretty easy estimation of losses
2019-03-08T16:52:35 < jadew> I've made a couple of those too, but the connectors I have are crap
2019-03-08T16:52:53 < jadew> I have a handfull of 3.5mm connectors, but didn't want to waste them on these cables

2019-03-08T16:57:08 < karlp> wat?
2019-03-08T16:57:15 < kakimir> read RM
2019-03-08T16:57:40 < kakimir> and if you ask such question I doubt that you need multi-master support
2019-03-08T16:57:49 < jadew> arc_phasor, even the most basic MCUs can deal with multi-master busses
2019-03-08T16:57:54 < arc_phasor> ok sweet
2019-03-08T16:58:06 < jadew> but yeah, check the RM to make sure
2019-03-08T16:58:39 < kakimir> some chips have like i2c slave only
2019-03-08T16:59:07 < arc_phasor> that would suck

2019-03-08T17:05:33 < bitmask> drivin' dirty
2019-03-08T17:06:05 < bitmask> been sitting for a year and the wheels/brakes rusted, got a caliper and brake pads replaced, the rotors should be ok for a while, gotta drive it a bit and see if anything else breaks :P
2019-03-08T17:09:09 < arc_phasor> bitmask: just get a tesla
2019-03-08T17:09:12 < jadew> bitmask, you could have just drove like that for a while
2019-03-08T17:09:19 < jadew> they would have cleaned up
2019-03-08T17:09:26 < arc_phasor> bitmask: that could all be fixed with a software update
2019-03-08T17:09:31 < bitmask> hah sure
2019-03-08T17:09:34 < jadew> happened to me too, when I had my license suspended for a couple of months
2019-03-08T17:09:40 < jadew> seriously
2019-03-08T17:09:55 < jadew> it sounds like shit for a couple of days, then it's back to normal
2019-03-08T17:10:06 < bitmask> some of it I'm sure will clean up with driving after I knock some more rust off, but one of the wheels was locked, and break pads isnt a bad thing
2019-03-08T17:10:17 < arc_phasor> i had a buddy who's car would rattle uncontrollably until about 60mph, then smooth sailing

2019-03-08T17:16:35 < arc_phasor> that's actually surprising they haven't done something super novel with the braking system
2019-03-08T17:17:13 < arc_phasor> still same old caliper and pad from the looks of it
2019-03-08T17:17:15 < zyp> like what?
2019-03-08T17:17:31 < arc_phasor> idk, something involving magnets 
2019-03-08T17:17:52 < zyp> well, they do regen braking, that involves magnets
2019-03-08T17:18:13 < zyp> but so does every other EV too, hardly novel at this point
2019-03-08T17:18:28 < arc_phasor> regen braking can't stop on a dime though i take it?
2019-03-08T17:18:32 < arc_phasor> hence the calipers and brake pads
2019-03-08T17:18:35 < zyp> exactly
2019-03-08T17:19:25 < arc_phasor> i guess whatever it is would have to stay purely mechanical in case of power failure
2019-03-08T17:19:28 < zyp> regen braking doesn't provide more stopping power than what can be fed back into the battery
2019-03-08T17:20:26 < zyp> that's why trains usually have huge resistor banks on the roof to burn off regenerated energy that can't be fed back into the grid
2019-03-08T17:20:40 < arc_phasor> interesting
2019-03-08T17:20:46 < arc_phasor> seems wasteful
2019-03-08T17:21:25 < zyp> not any more wasteful than using the energy to heat up brake discs
2019-03-08T17:21:46 < zyp> and load resistors can dissipate the energy better

2019-03-08T17:30:12 < arc_phasor> do you think original tesla will still be running in 20 years?
2019-03-08T17:30:23 < arc_phasor> what's life span of these thangs
2019-03-08T17:30:44 < zyp> idk, most EVs here have an 8 year warranty on the battery
2019-03-08T17:31:05 < arc_phasor> battery tech is always getting better too
2019-03-08T17:31:24 < arc_phasor> it might end up being all super-caps in 10 years, charging in 1 minute and lasting for 1000 miles
2019-03-08T17:31:42 < zyp> mitrax, it's controled by the DIV_0_TRP in SCB_CCR
2019-03-08T17:31:51 < mitrax> i want to test a hardfault handler, it's been called before due to bugs etc, but for some reason i can't get it to trigger, even when dereferencing a null pointer or when dividing by zero the program keeps running
2019-03-08T17:31:59 < mitrax> thanks, let me check
2019-03-08T17:32:05 < zyp> CM4 TRM doesn't appear to say what the default is
2019-03-08T17:32:17 < zyp> I'm guessing it might be implementation defined

2019-03-08T17:35:39 < arc_phasor> dayum, is the battery modular in such a way you can "pop it out" for an upgrade?
2019-03-08T17:35:49 < zyp> no
2019-03-08T17:36:13 < arc_phasor> that sucks
2019-03-08T17:36:17 < zyp> I'm not overly concerned about the range
2019-03-08T17:37:00 < arc_phasor> how many miles?
2019-03-08T17:37:01 < zyp> according to my estimate, when the battery warranty runs out when the car is eight years old, I would have saved around half the cost of the car just in reduced fuel costs

2019-03-08T19:38:34 < Cracki> might that be significant
2019-03-08T19:38:44 < Cracki> does their thing give non-zero?

2019-03-08T19:39:41 < jadew> what a fucking joke... I had to register to download the "test data", which was a doc, with a single page containing a scan from a print-screen with the part name written by hand, showing the properties from 10 MHz to 2 GHz, for a connector that's supposed to work up to 11 GHz
2019-03-08T19:39:43 < rajkosto> honestly, i'd rather just generate all the "calibrated" data through my own code, if they gave me the algo
2019-03-08T19:39:55 < Cracki> kek
2019-03-08T19:40:02 < rajkosto> its slow to fetch all these bytes through i2c
2019-03-08T19:40:25 < rajkosto> (cuz its virtual i2c provided by their mcu, so theres polling involved for ready/done for each byte)

2019-03-08T22:17:09 < zyp> haven't had time to play with it yet, working on something else now
2019-03-08T22:17:23 < catphish> :)

2019-03-08T22:18:05 < kakimir> but this fucker has this passive air heat exchanger that has thermostat to keep it warm too
2019-03-08T22:18:16 < zyp> and then I put off doing more work on that by going to ikea and picking up more kitchen parts
2019-03-08T22:18:30 < zyp> so now I'm working on putting together more of the kitchen :p
2019-03-08T22:18:45 < kakimir> and that thing is heated with electricity
2019-03-08T22:19:02 < kakimir> warm months I can pay like 10eur a month of electricity
2019-03-08T22:19:18 < kakimir> then it get's a bit colder and suddenly 30-40eurs
2019-03-08T22:19:51 < zyp> heh
2019-03-08T22:20:02 < zyp> power bill here is like five times that

2019-03-08T22:20:35 < kakimir> with rent included heating
2019-03-08T22:20:39 < mawk> ah
2019-03-08T22:20:56 < zyp> mawk, last time I looked at miners, ROI is pretty fucking long even assuming free electricity
2019-03-08T22:21:02 < kakimir> crypto stove was nice idea
2019-03-08T22:21:09 < mawk> yeah zyp 
2019-03-08T22:21:11 < catphish> we use plain electric heating in my office
2019-03-08T22:21:12 < kakimir> it just came out too late
2019-03-08T22:21:17 < catphish> i wonder if mining would be a sensible idea
2019-03-08T22:21:23 < mawk> but here you add the generated heat to the benefits, and it suddenly has a good ROI
2019-03-08T22:21:36 < mawk> or better at least
2019-03-08T22:21:54 < kakimir> still it will lose to A/C based heating
2019-03-08T22:22:01 < catphish> of course
2019-03-08T22:22:07 < catphish> heat pumps ftw
2019-03-08T22:22:11 < kakimir> both initial investment and operation cost
2019-03-08T22:22:12 < zyp> mawk, no
2019-03-08T22:22:31 < mawk> it's just mechanic, on one side heat is counted as loss, on the other it's a gain
2019-03-08T22:22:47 < zyp> mawk, beneficial heat just means electricity is free since you would have used it anyway
2019-03-08T22:23:29 < zyp> so you don't get any benefits on top of that
2019-03-08T22:24:32 < zyp> and last I checked, ROI on a miner was like 7-8 months even when not accounting for difficulty increase
2019-03-08T22:24:44 < zyp> I mean, break even
2019-03-08T22:24:56 < zyp> with difficulty increase, you probably need a year to break even
2019-03-08T22:25:23 < mawk> right

2019-03-08T22:28:06 < mawk> I want bitcoin too Steffanx 
2019-03-08T22:28:30 < zyp> I think I've put like 1k€ into that pile, not sure how much it's worth today
2019-03-08T22:29:02 < mawk> with the recent crash certainly less than some months ago
2019-03-08T22:29:07 < mawk> but you can never know
2019-03-08T22:29:14 < mawk> some voodoo/"technical analysis" guys pretend they do
2019-03-08T22:29:28 < Steffanx> it was like 5 euro in buttcoin when i gave it to zyp. or something close to that
2019-03-08T22:29:31 < zyp> yeah, but all of it was bought in 2018, most of it before the huge spike
2019-03-08T22:29:38 < jpa-> i put 100e or something into bitcoin & ethereum when it was rising, took some 300e out; found out later that i don't even have to pay any capital gain taxes because it was less than 1ke
2019-03-08T22:30:16 < Steffanx> would you even when > 1k?
2019-03-08T22:30:25 < Steffanx> isnt buttcoin the money of the free people
2019-03-08T22:30:35 < zyp> I think I had like 3k€ or 4k€ worth at some point, and now it's probably back to around where it was when I bought it

2019-03-08T22:37:06 < zyp> Steffanx, and yeah, I don't really expect it to spike that dramatically again, that's why I figure that money is lost already :p

2019-03-08T23:19:06 < zyp> yeah
2019-03-08T23:19:26 < zyp> all the money people have taken out of bitcoin is money other people put into it :p
2019-03-08T23:20:04 < rajkosto> and any of the whales sitting on tons of coins can make the price plummet by dumpin
2019-03-08T23:20:04 < jadew> almost like a ponzi scheme
2019-03-08T23:20:21 < rajkosto> wealth distirbution is insanely skewed
2019-03-08T23:20:28 < englishman> all those real dollars would have gone to alcohol or other gambling companies anyway so no big loss really
2019-03-08T23:22:28 < zyp> I saw the first tesla model 3 I've seen in the wild today
2019-03-08T23:22:41 < englishman> small isnt it
2019-03-08T23:22:44 < kakimir> if you invent general quantum computer
2019-03-08T23:22:57 < zyp> drove behind a car with EV plates, didn't recognize the shape
2019-03-08T23:23:07 < zyp> then I spotted the tesla logo
2019-03-08T23:23:27 < jadew> how much is it?
2019-03-08T23:23:27 < kakimir> can you just pop out any difficulty hash in constant amount of cycles?
2019-03-08T23:23:35 < jadew> is this one supposed to be cheaper?
2019-03-08T23:23:38 < zyp> didn't really have a good look, I drove past it in the other lane
2019-03-08T23:23:51 < zyp> kakimir, no
2019-03-08T23:24:27 < zyp> jadew, it's supposed to be cheap, haven't looked at how cheap
2019-03-08T23:25:08 < jadew> my wife wants us to get an electric car, but it's not a good fit for us, living in an apartment building
2019-03-08T23:25:29 < zyp> hmm, more expensive than I thought
2019-03-08T23:25:34 < jadew> we'd have to install a charging station next to our parking spot (it's doable, but...)
2019-03-08T23:25:48 < zyp> looks like 43k€ for the cheapest variant here
2019-03-08T23:25:52 < Cracki> why does she want it, because it's hip or because it's (obviously not) a good idea?
2019-03-08T23:26:01 < englishman> cheapest one is still 50kWh
2019-03-08T23:26:06 < Cracki> does she just want to waste money
2019-03-08T23:26:09 < englishman> but kona kinda beats that
2019-03-08T23:26:11 < zyp> englishman, only 50?
2019-03-08T23:26:18 < englishman> "autopilot" that doesnt exist yet costs an extra 20k too
2019-03-08T23:26:29 < jadew> Cracki, I think to save money on gas and... because it's hip
2019-03-08T23:26:35 < kakimir> future is here
2019-03-08T23:26:48 < jadew> kakimir, where's my hoverboard?
2019-03-08T23:27:00 < kakimir> cars drive autonomously
2019-03-08T23:27:12 < Cracki> uh, has she calculated the cost of a kilometer electrically and with gas?
2019-03-08T23:27:40 < englishman> zyp the 50kWh is the $35k usd model and at that price there is not a lot of competition
2019-03-08T23:27:54 < jadew> kakimir, pff... to paraphrase Shania, "that don't impress me much".
2019-03-08T23:27:54 < Cracki> has she calculated the breakeven point
2019-03-08T23:27:56 < Cracki> :P
2019-03-08T23:28:14 < englishman> of course they want $2k for paint that isnt black, so the $35k model will be quite rare
2019-03-08T23:28:21 < kakimir> jadew: me neather
2019-03-08T23:28:21 < jadew> she hasn't, I have, at one point
2019-03-08T23:28:48 < zyp> englishman, I suspect that's not available here

2019-03-08T23:29:10 < englishman> but idk there are too many models
2019-03-08T23:29:15 < englishman> and their website doesnt tell you shit
2019-03-08T23:29:17 < englishman> which is a red flag
2019-03-08T23:29:25 < jadew> Cracki, electric is better, but you have to live with the downsides
2019-03-08T23:29:25 < zyp> cheapest model is called «Long Range», can't find anywhere they state the actual battery capacity, but it says 530 km according to WLTP
2019-03-08T23:29:36 < zyp> hmm
2019-03-08T23:29:47 < zyp> here only Long Range and Performance is available
2019-03-08T23:29:51 < zyp> the latter is more expensive
2019-03-08T23:29:52 < jadew> Cracki, depends on which cars you're comparing too
2019-03-08T23:29:55 < englishman> "long range" is 75kWH
2019-03-08T23:30:06 < zyp> ah
2019-03-08T23:30:08 < Cracki> you can probably put a price on the downsides
2019-03-08T23:30:16 < englishman> performance adds some horsepower to the awd model
2019-03-08T23:30:33 < zyp> they are both AWD
2019-03-08T23:30:40 < zyp> seems they don't sell non-AWD TM3 here
2019-03-08T23:30:40 < englishman> ah, it is an option here
2019-03-08T23:30:54 < zyp> hmm
2019-03-08T23:30:54 < englishman> anyway without awd there is just a big empty space in the front
2019-03-08T23:31:01 < zyp> «estimated delivery in march»
2019-03-08T23:31:05 < zyp> wonder what year :p
2019-03-08T23:31:21 < englishman> avoid
2019-03-08T23:31:22 < englishman> imop
2019-03-08T23:31:56 < zyp> but I mean
2019-03-08T23:31:56 < englishman> the first few hundred model S will be out of warranty this year
2019-03-08T23:32:15 < englishman> so we will start hearing about repairs horror stories only a few years from now still
2019-03-08T23:32:20 < zyp> so far in march there's 782 TM3 registered in norway
2019-03-08T23:32:58 < englishman> already the ones under warranty are: leave the car with the dealer for 8 months while you make payments on it and they wait for parts
2019-03-08T23:32:58 < zyp> on the other hand, there's 796 hyundai kona registered so far in 2019 :p
2019-03-08T23:33:19 < englishman> yeah, it is a nice looking car
2019-03-08T23:33:33 < zyp> my friend finally got his kona a few weeks ago
2019-03-08T23:33:37 < zyp> after a bunch of delays :p
2019-03-08T23:34:01 < zyp> haven't had a chance to drive it yet, but he seems happy with it
2019-03-08T23:34:31 < englishman> hopefully they depreciate as fast as the leafs
2019-03-08T23:34:40 < zyp> hehe
2019-03-08T23:34:40 < englishman> so i can get one in 2-3 years for 15k
2019-03-08T23:35:31 < zyp> I figure I'll be keeping the egolf for another while

2019-03-09T01:05:17 < Cracki> not liking the extra cost for 2oz copper?
2019-03-09T01:09:22 < zyp> hmm
2019-03-09T01:09:50 < zyp> got the stm32wb hooked up and ready to be loaded some code onto
2019-03-09T01:10:28 < zyp> and I'm now realizing another reason it's fucking annoying that the radio firmware is encrypted
2019-03-09T01:11:02 < rajkosto> cant comrpess it /
2019-03-09T01:11:18 < zyp> it means I'll have to dick around with special tools to even load it
2019-03-09T01:12:08 < zyp> I mean, there's apparently an unpublished appnote about how to work with the security system, but I don't have that
2019-03-09T01:12:32 < Cracki> it's a blob that needs to go into the right address, yes? sounds like _at worst_ you wanna turn that into an array of hex values for C code
2019-03-09T01:12:43 < zyp> no
2019-03-09T01:12:56 < Cracki> "encrypted" means more fuckery then?
2019-03-09T01:13:14 < zyp> the flash area it's going into is inaccessible by CPU1
2019-03-09T01:13:44 < zyp> there's some sort of security code also located in the inaccessible area that'll handle decryption
2019-03-09T01:14:33 < zyp> but as far as I can tell, CPU2 can't bootload itself, so it still needs code on CPU1 that can feed the encrypted blob to the code on CPU2
2019-03-09T01:14:52 < zyp> and I figure the docs on how to do that is the appnote I mentioned
2019-03-09T01:15:25 < Cracki> wow
2019-03-09T01:15:41 < zyp> it'd be a lot more convenient if it was just a plain blob to load at a specific address
2019-03-09T01:16:27 < zyp> also, this means that it's more or less impossible to run anything but ST code on CPU2
2019-03-09T01:16:48 < Cracki> ...
2019-03-09T01:17:12 < rajkosto> why woudl you want to run anything but pre-approved vendor code that does exactly what you want
2019-03-09T01:17:52 < zyp> it _might_ be possible to disable security (prerelease of the RM documents how, released version doesn't)
2019-03-09T01:18:52 < zyp> but doing so involves a full chip erase, so that'll also throw out the decryption blob, making it impossible to ever load the encrypted firmwares again
2019-03-09T01:19:10 < Cracki> maybe someone's gonna glitch that out of it
2019-03-09T01:19:27 < zyp> yeah
2019-03-09T01:20:41 < zyp> I mean, the security model relies on every part shipping with a copy of the same encryption keys, only takes one leak to defeat the whole thing
2019-03-09T01:21:58 < zyp> IMO this is bullshit :p
2019-03-09T01:22:19 < zyp> the hardware is cute, but I just want the register interface to the radio so I can write my own radio stack

2019-03-09T01:23:29 < zyp> at least the bullshit is contained on CPU2
2019-03-09T01:24:10 < zyp> linking in a binary blob that'll share a cpu with your own code is more annoying
2019-03-09T01:24:22 < rajkosto> Keil libs only
2019-03-09T01:24:37 < jadew> zyp, any idea on why they went through all this trouble to do this?
2019-03-09T01:24:57 < zyp> I can at least load the plain 802.15.4 radio firmware to CPU2 and just write my own stack on top of that to run on CPU1
2019-03-09T01:25:04 < rajkosto> because they dont want people openly analyzing the horribly explitable radio stack's rtos ?
2019-03-09T01:26:01 < jadew> well, the OS should be able to handle bad shit coming in, no?
2019-03-09T01:26:29 < zyp> jadew, I figure it's some mix of IP protection and enforcing spectrum rules for the radio
2019-03-09T01:27:39 < jadew> zyp, that's what I thought too, maybe this is how they can claim compliance
2019-03-09T01:28:04 < zyp> still seems extreme
2019-03-09T01:28:09 < jadew> so it's possible the radio can do a lot more
2019-03-09T01:28:42 < jadew> well, you need a license for every band your radio operates in
2019-03-09T01:29:25 < jadew> if they make sure it only does ISM stuff, then there's nothing to worry about
2019-03-09T01:30:11 < zyp> if you wanna use another band, just detune it by changing the main crystal :p
2019-03-09T01:30:23 < jadew> hah
2019-03-09T01:30:53 < zyp> could be it has countermeasures against that too, could be comparing HSE to one of the internal oscillators
2019-03-09T01:30:59 < zyp> but still :p
2019-03-09T01:31:13 < jadew> you could finally get a channel for yourself
2019-03-09T01:32:15 < zyp> anyway, I wanna make a hello world app for this shit, then start bringing up peripherals
2019-03-09T01:33:04 < zyp> I figure usb shouldn't be too hard to get going, seems like this is closely related to l4, which is similar to l0, which I've already got plenty support for
2019-03-09T01:33:47 < zyp> but before I erase whatever is on it now, I should probably load the radio firmware I'll be using later
2019-03-09T01:34:04 < zyp> which is what got me annoyed :p
2019-03-09T01:36:11 < zyp> hmm
2019-03-09T01:37:44 < zyp> okay, maybe this shit is actually halfway sane, looks like the updater tool might be loading a temporary loader into SRAM to run on CPU1
2019-03-09T01:37:55 < zyp> to bridge between USB and CPU2

2019-03-09T03:30:41 < jadew> so you can make stencils?
2019-03-09T03:30:53 < Cracki> haha they're having to shoot at it for a minute before it's through

2019-03-09T03:36:11 < Cracki> that should give you pause
2019-03-09T03:37:15 < Cracki> maybe it IS a good idea to shoot the cop before it shoots you

2019-03-09T14:30:26 < PeterM> im having performance issues in oldschool runescape, i should probably upgrade my 1080ti to a 2080
2019-03-09T14:31:08 < srk> problem with linux is that such GPU kind-of needs it's own kernel so you have kernel in kernel for this "special" multicore FPU
2019-03-09T14:32:42 < PeterM> thats ok, nobody uses lunix anyway, so doesnt really effect anyone, and on windows someone else (nvidia) takes care of all that for you
2019-03-09T14:32:55 < englishman> https://www.worksonmymachine.pro/
2019-03-09T14:32:58 < srk> totally
2019-03-09T14:33:34 < srk> PeterM: taking care by downloading 500Mb installer with proprietary drivers and some bloatware lol
2019-03-09T14:33:50 < Steffanx> Yeah. The nvidia experience.
2019-03-09T14:33:54 < srk> because they can't even distribute the driver with OS xD
2019-03-09T14:34:44 < PeterM> i dunno, never had an issue with bloatwear, i guess i dont notice it since im not using some 15 year old ibm laptop
2019-03-09T14:34:47 < BrainDamage> the nvidia driver is 11.8MB
2019-03-09T14:35:08 < srk> yeah, run some pro tools on your pro hardware
2019-03-09T14:35:19 < srk> like anyone gives a fuck
2019-03-09T14:35:45 < srk> better go to pro slack, heard that it's like IRC for modern computers
2019-03-09T14:36:26 < Steffanx> Im temptes to mentiom haskell, but srk no longer likes it :P
2019-03-09T14:36:30 < Steffanx> Mention*
2019-03-09T14:36:46 < srk> no, just step up your trolling 
2019-03-09T14:37:00 < PeterM> wait, you cant run two programs at once? i've got both irc and slack running
2019-03-09T14:37:02 < srk> cause it's boring to repeat same shit over and over
2019-03-09T14:37:27 < srk> no I only have 1 core and programs on tape
2019-03-09T14:38:14 < PeterM> sheeeeeet, give me your address and i'll mail you some old hardware
2019-03-09T14:38:15 < englishman> are 15 year old IBM laptops supported in lunix yet?
2019-03-09T14:38:21 < srk> ppl who think that some proprietary shite browser chat is a good idea lol
2019-03-09T14:38:37 < PeterM> englishman im pretty sure they jsut got the wifi drivers sorted
2019-03-09T14:39:04 < englishman> lunix has drivers now?
2019-03-09T14:39:20 < BrainDamage> fun fact, 15 year old ibm laptops are particularly fetishised among lunix users, for multiple reasons

2019-03-09T14:43:18 < PeterM> nah, probably a month or so ago, had to do some stuff on an rpi

2019-03-09T14:44:27 < englishman> rapsbian is pretty nice too, smoothest install of any lunix, graphical config utility

2019-03-09T14:46:02 < englishman> doesn't everything on lunix work like that
2019-03-09T14:46:30 < srk> no, there's usually a pretty standardized way how to do *common* stuff
2019-03-09T14:46:40 < englishman> need camera, install uvc

2019-03-09T15:55:53 < bitmask> hi hi hi
2019-03-09T15:59:24 < Steffanx> Goodday sir
2019-03-09T15:59:31 < bitmask> how do you do?
2019-03-09T16:00:09 < Steffanx> Good enough. There?
2019-03-09T16:00:11 < bitmask> its wonderful to have my car back, now I just need monies to fill her gas hole
2019-03-09T16:00:29 < bitmask> good enough as well
2019-03-09T16:00:34 < Steffanx> did they take your car?
2019-03-09T16:01:17 < bitmask> it was sitting for a year outside and rusted, brought it to the shop last week and just got it back yesterday
2019-03-09T16:01:26 < bitmask> gonna need more work but its good for now
2019-03-09T16:02:01 < bitmask> got new pads in the back and a brake caliper and hose on one side, rotors should be ok for a while
2019-03-09T16:02:16 < bitmask> the front is gonna need more work but at least none of the wheels were locked up so I can wait a while for it
2019-03-09T16:14:55 < bitmask> is there anyway to measure power supply noise without a scope?
2019-03-09T16:15:20 < jadew> with a spectrum analyzer
2019-03-09T16:15:28 < bitmask> that sounds more expensive 
2019-03-09T16:15:29 < bitmask> :P
2019-03-09T16:15:32 < jadew> :)
2019-03-09T16:16:57 < bitmask> figured Id get a little lab power supply for my bday, the DPS5015
2019-03-09T16:17:34 < jadew> how much is it?
2019-03-09T16:17:45 < bitmask> $60 with the case
2019-03-09T16:17:54 < jadew> hmm
2019-03-09T16:17:54 < bitmask> and usb/bluetooth
2019-03-09T16:18:04 < jadew> you can probably get something better in that range
2019-03-09T16:18:43 < jadew> looks ok I guess
2019-03-09T16:18:47 < jadew> did you already get it?
2019-03-09T16:18:51 < bitmask> I was thinking with this I could eventually add a 5005 for a dual supply and maybe have a switch that switches the output to go through a linear ldo for less noise?
2019-03-09T16:18:58 < bitmask> no not yet
2019-03-09T16:19:27 < jadew> a linear regulator will reduce noise, yes
2019-03-09T16:19:37 < jadew> but might not reduce it as much as you'd want, depending on the noise
2019-03-09T16:20:07 < jadew> how much is the 5005?
2019-03-09T16:20:14 < bitmask> I'm not into very high precision stuff (yet?) so I"m not sure what I want but this just seemed like a more configurable option
2019-03-09T16:20:18 < bitmask> $27
2019-03-09T16:20:24 < bitmask> without case
2019-03-09T16:20:40 < jadew> oh, I thought the 5005 was the Korad one
2019-03-09T16:21:15 < bitmask> the 5005 has more precision which is why id get that instead of a second 5015
2019-03-09T16:21:44 < jadew> why don't you get a linear one?
2019-03-09T16:22:17 < bitmask> they have linear bench psus? isnt that really inefficient?
2019-03-09T16:22:46 < jadew> they do, they have the cleanest output
2019-03-09T16:23:00 -!- gsi__ is now known as gsi_
2019-03-09T16:23:18 < jadew> and you don't care about efficiency in the lab anyway
2019-03-09T16:24:05 < bitmask> ehh I think id be fine with a switching for the main unit and then like I mentioned, add a ldo linear as an output option if I decide I want to clean it up
2019-03-09T16:24:34 < jadew> if you need to use a bunch of other crap after the supply, it kinda defeats the purpose
2019-03-09T16:24:44 < jadew> you'll then have to set the voltage from that thing
2019-03-09T16:24:49 < jadew> rather than from the PSU
2019-03-09T16:25:12 < bitmask> I was looking at the TPS7A4700 and some other one
2019-03-09T16:25:44 < bitmask> yea but thats not for a common use case, i mean if you know of a linear option in that price range I'm open to suggestions but this doesnt seem that annoying
2019-03-09T16:26:01 < jadew> this looks ok: https://www.amazon.com/Tekpower-TP3005TN-Variable-Alligator-Switchable/dp/B07G4HVD5M/ref=pd_day0_hl_469_8
2019-03-09T16:26:22 < jadew> that's what I found on a quick serach
2019-03-09T16:26:26 < jadew> I'm sure you can be more picky
2019-03-09T16:26:32 < jadew> look for more buttons, etc
2019-03-09T16:27:13 < bitmask> yea but its already more expensive with much lower output, I mean I guess I probably don't need 50V or 15A but I'll have to think about it
2019-03-09T16:28:30 < jadew> do you even have banana cables that can do 15 A?
2019-03-09T16:28:56 < bitmask> I dont have any, thats another purchase
2019-03-09T16:29:17 < jadew> I guess it depends what you're into
2019-03-09T16:29:25 < jadew> for me, precision is key
2019-03-09T16:29:27 < bitmask> yea I guess I gotta think about it
2019-03-09T16:30:09 < bitmask> thanks for the info though, you definitely complicated things but I guess its better to get the right product :)
2019-03-09T16:30:21 < jadew> heh, you're welcome
2019-03-09T16:35:36 < bitmask> oh I guess these units include the power supply itself too right? 
2019-03-09T16:35:46 < bitmask> the ones I mentioned dont
2019-03-09T16:35:51 < jadew> which units?
2019-03-09T16:35:56 < jadew> the one I linked?
2019-03-09T16:35:59 < bitmask> like the linear one you linked
2019-03-09T16:36:08 < jadew> yeah, that's a proper lab power supply
2019-03-09T16:36:29 < bitmask> alright, I guess I should do that, the one I was talking about was just a step down unit
2019-03-09T16:36:34 < jadew> I don't know anything about the one I linked, but I only gave it as an example for what you should be looking for
2019-03-09T16:36:41 < bitmask> right
2019-03-09T16:39:27 < jadew> this is a popular one: https://www.amazon.com/KORAD-KA3005D-Precision-Adjustable-Regulated/dp/B0084JFWNY
2019-03-09T16:39:31 < jadew> there's a version with USB too
2019-03-09T16:40:08 < bitmask> whys it gotta look so old :P
2019-03-09T16:40:53 < jadew> probably because it doesn't matter :)

2019-03-09T17:52:32 < dongs> it protects pluto from chinaamp output

2019-03-09T18:29:26 < mawk> maybe you want something else than a photoresistor

2019-03-09T18:31:15 < jadew> rajkosto, a photo diode
2019-03-09T18:31:33 < jadew> ah, I misread the question
2019-03-09T18:32:31 < rajkosto> i want a 10000fps single pixel camera
2019-03-09T18:34:46 < jadew> so get a photo diode
2019-03-09T18:34:57 < jadew> do you need to know color too?
2019-03-09T18:34:59 < rajkosto> isnt that digital
2019-03-09T18:35:00 < rajkosto> yes
2019-03-09T18:35:12 < jadew> it's not
2019-03-09T18:35:19 < jadew> then get 3 photo diodes
2019-03-09T18:36:53 < rajkosto> how do you get a linear intensity reading off photo diodes
2019-03-09T18:37:50 < jadew> with math
2019-03-09T18:38:17 < jadew> depends on how much light you shine on them
2019-03-09T18:38:27 < jadew> but at the lower end, they're not linear
2019-03-09T18:38:34 < rajkosto> plenty.
2019-03-09T18:38:34 < jadew> after that part is done, they're fairly linear
2019-03-09T18:40:05 < jadew> then you might not have to deal with the non-linearities, but again, depends on your application
2019-03-09T18:40:22 < jadew> if you want perfect linearity, there's still something to correct there
2019-03-09T18:40:40 < rajkosto> its all going to a computer for processing anyway
2019-03-09T18:41:31 < jadew> the slope is still logarithmic, but depending on your dynamic range, it might look linear enough
2019-03-09T18:43:38 < rajkosto> actually for what i want to do i can totally just characterize it before use
2019-03-09T18:43:48 < BrainDamage> rajkosto: https://i.imgur.com/1gMRYjn.png
2019-03-09T18:44:02 < BrainDamage> this will give a linear output with light intensity
2019-03-09T18:44:23 < BrainDamage> however, you want a photodiode with very low dark current if you plan to use it at high speed
2019-03-09T18:44:51 < BrainDamage> because the shot noise of the dark current is what compares to the integral of your light signal in the shutter time
2019-03-09T18:44:55 < BrainDamage> for the SNR
2019-03-09T18:45:04 < mawk> senza titolo
2019-03-09T18:45:33 < BrainDamage> sans titre
2019-03-09T18:46:06 < BrainDamage> oh and the resistor I just slapped a random 50Ohm, but you actually want it pretty large
2019-03-09T18:46:20 < Laurenceb_123> just get a APD tbh
2019-03-09T18:46:21 < BrainDamage> 10MOhm or more
2019-03-09T18:46:40 < Laurenceb_123> or one of these babies 
2019-03-09T18:46:41 < Laurenceb_123> https://sensl.com/

2019-03-09T18:48:09 < scrts> hey lads
2019-03-09T18:48:17 < scrts> does anyone have parallella board?
2019-03-09T18:48:32 < Laurenceb_123> why.jpg
2019-03-09T18:49:06 < Laurenceb_123> I was thinking of haxoring some of those sensl detectors to 10Mbps ethernet and trying to set free space optical comms record
2019-03-09T18:49:15 < Laurenceb_123> but it would be pointless and lame tbh
2019-03-09T18:49:55 < BrainDamage> rajkosto: that limits your light sensitivity to a lux or so
2019-03-09T18:50:20 < scrts> https://pbs.twimg.com/media/D1JypcnWsAA8Sr6.jpg:large
2019-03-09T18:50:36 < BrainDamage> are those nail clippings?
2019-03-09T18:50:45 < jadew> yeah, but it looks fake
2019-03-09T18:51:00 < jadew> who clips their nails on top of the keyboard?
2019-03-09T18:51:02 < dongs> looks like my clipboard
2019-03-09T18:51:02 < BrainDamage> there's quite a few in my keyboard, but not as many
2019-03-09T18:51:07 < dongs> err
2019-03-09T18:51:08 < dongs> keyboard
2019-03-09T18:51:12 < BrainDamage> someone who bites their nails
2019-03-09T18:51:19 < jadew> ah
2019-03-09T18:51:30 < jadew> I thought people who do that also swallow them
2019-03-09T18:51:38 < scrts> dunno
2019-03-09T18:51:39 < scrts> https://pbs.twimg.com/media/D1LRcg1WoAAaIPs.jpg:large
2019-03-09T18:51:40 < jadew> I guess some might spit them out
2019-03-09T18:51:48 < jadew> lol
2019-03-09T18:51:57 < jadew> that looks disgusting
2019-03-09T18:52:19 < rajkosto> thanks for making me slightly vommy
2019-03-09T18:52:25 < Laurenceb_123> kek wut
2019-03-09T18:52:39 < jadew> I found nails in mine too, but just one or two
2019-03-09T18:52:58 < mawk> I have resistors under my keys, not nails
2019-03-09T18:53:18 < mawk> it's not a mech keyboard so I can't remove the key caps, so it's stuck there for life
2019-03-09T18:54:19 < jadew> even if it's glued, you can still get to it with enough force
2019-03-09T18:54:35 < jadew> *if the keys are glued
2019-03-09T18:54:42 < mawk> I can remove them, but not put them back
2019-03-09T18:54:49 < mawk> some piece of plastic snaps
2019-03-09T18:55:01 < jadew> you should get a proper keyboard
2019-03-09T18:56:30 < jadew> mine is 8 years old and still going strong
2019-03-09T18:56:34 < mawk> my girlfriend complained about the noise when I had a mechanical keyboard
2019-03-09T18:56:43 < mawk> even though I got what was marketed as silent keys
2019-03-09T18:56:47 < mawk> cherry mx silent or something
2019-03-09T18:57:09 < jadew> why are there people around you when you're using the PC?
2019-03-09T18:57:20 < mawk> my appartment is too small
2019-03-09T18:57:26 < mawk> there just a bedroom, and that's all
2019-03-09T18:57:31 < jadew> ah
2019-03-09T18:57:32 < mawk> kitchen, bathroom, but I can't code in there
2019-03-09T18:57:56 < mawk> appartments are a bit expensive where I am
2019-03-09T18:58:04 < mawk> it's around 30-40€ per square meter
2019-03-09T18:58:44 < jadew> you should move
2019-03-09T18:59:05 < mawk> I'm near my school
2019-03-09T18:59:39 < jadew> how old are you?
2019-03-09T19:00:24 < englishman> rajkosto: usually they use a chopper and lock in amplifier

2019-03-09T21:39:55 < kakimir> hello lurencer
2019-03-09T21:42:50 < englishman> so i have a 240V 15A device, it turns off and on its own, but if it runs for too long, i want it to shut off and stay off or stay off for a predetermined time
2019-03-09T21:43:02 < englishman> what is that controller called, i think bypass timer comes to mind
2019-03-09T21:43:08 < englishman> and where do i get one for $10
2019-03-09T21:46:07 < Laurenceb_123> https://imgoat.com/uploads/eabe3a1649/205067.jpg aww I thought they would get on well as a couple
2019-03-09T21:47:07 < Laurenceb_123> the answer is China I suspect
2019-03-09T21:47:46 < malinus> englishman: "digital timer 240V" or "analog timer 240V"
2019-03-09T21:48:32 < englishman> that just returns a bunch of grow light cycle timers tho

2019-03-10T00:00:15 < englishman> techno is classical music
2019-03-10T00:01:41 < rajkosto> guess ill use the internal ADC then
2019-03-10T00:02:17 < rajkosto> which are trash
2019-03-10T00:04:26 < Laurenceb_123> wut
2019-03-10T00:04:34 < Laurenceb_123> stm32 adc is v good
2019-03-10T00:07:08 < Laurenceb_123> although my maya 44 sound card is impressive, 15enob at 48ksps
2019-03-10T00:07:21 < Laurenceb_123> hard to achieve with stm32
2019-03-10T00:07:50 < Laurenceb_123> but it uses about 1W O_o
2019-03-10T00:09:38 < englishman> if i want to know how for how much time something has been on in the last 24 hours, in order to not use a lot of flash or ram and survive reboots, is sending all data to influxdb and querying it the best way
2019-03-10T00:11:11 < Laurenceb_123> my sides
2019-03-10T00:11:29 < englishman> why do you fail so bad at influxdb
2019-03-10T00:11:35 < englishman> you just send an mqtt thing, and its there
2019-03-10T00:11:35 < Laurenceb_123> use battery backed ram or something
2019-03-10T00:11:45 < englishman> esp32 is cheaper than fram
2019-03-10T00:11:49 < Laurenceb_123> wait it accepts mqtt?
2019-03-10T00:11:50 < englishman> or battery backed ram
2019-03-10T00:11:53 < englishman> of course, dingus
2019-03-10T00:12:05 < Laurenceb_123> hmm maybe that would be faster than deranged ascii
2019-03-10T00:12:15 < englishman> HMM MAYBE
2019-03-10T00:12:25 < jadew> englishman, who needs to know?
2019-03-10T00:12:31 < englishman> me
2019-03-10T00:12:33 < jadew> the device itself or something external?
2019-03-10T00:12:40 < englishman> i am external to the device
2019-03-10T00:12:43 < jadew> so something external
2019-03-10T00:12:46 < englishman> yes
2019-03-10T00:13:03 < englishman> i think influxdb is made for exactly that
2019-03-10T00:13:28 < jadew> has to be wireless?
2019-03-10T00:13:34 < englishman> im sure there is some nice and clean way to count seconds a pin is high in the last 24 hours

2019-03-10T00:14:39 < englishman> you mean like, everything these days

2019-03-10T00:15:33 < Laurenceb_123> internet of power hungry shit
2019-03-10T00:16:13 < jadew> if it's wired, you can have another device monitoring that, if it's not and you have internet access, just make a server and ping something
2019-03-10T00:16:22 < englishman> grafana is querying my influxdb and it says i used 4.73MWh in the last 30 days
2019-03-10T00:16:30 < englishman> so i dont really give a shit about another esp32
2019-03-10T00:16:33 < jadew> if it stays awake a long time, you can ping when it wakes up and when it goes to sleep
2019-03-10T00:17:31 < jadew> that's the smallest footprint, code wise
2019-03-10T00:17:33 < jadew> and ram wise
2019-03-10T00:17:39 < jadew> a simple connect
2019-03-10T00:17:40 < Laurenceb_123> wtf are you doing
2019-03-10T00:17:44 < jadew> then you close the socket
2019-03-10T00:17:44 < Laurenceb_123> I cant even right now
2019-03-10T00:17:54 < Laurenceb_123> 4.73MWh
2019-03-10T00:17:56 < jadew> you can even write a 1 or a 0
2019-03-10T00:18:25 < jadew> and from the little server getting that, you can put the data wherever you want

2019-03-10T01:32:09 < mawk> yeah I saw that
2019-03-10T01:32:15 < mawk> I queried your client with my haxxor skills
2019-03-10T01:32:20 < mawk> and it said weechat 2.4
2019-03-10T01:32:28 < Steffanx> 👍🏾
2019-03-10T01:32:29 < jadew> it's back on milliseconds
2019-03-10T01:32:38 < mawk> is it a vulnerability or a mere graphic bug, that's the question
2019-03-10T01:32:41 < jadew> I wonder how long it takes until it gets back
2019-03-10T01:32:45 < englishman> weechat is gr8
2019-03-10T01:32:48 < mawk> you can do ctrl-L jadew 
2019-03-10T01:32:51 < mawk> to refresh the display
2019-03-10T01:33:01 < jadew> ok, it was a graphic bug
2019-03-10T01:33:12 < jadew> maybe a screen issue?
2019-03-10T01:33:19 < mawk> a xterm issue I'd say
2019-03-10T01:33:33 < mawk> it's xterm that interprets the color codes and other escape codes
2019-03-10T01:33:41 < jadew> not using xterm
2019-03-10T01:33:43 < englishman> sounds complicated
2019-03-10T01:33:47 < mawk> and multibyte emojis may be mistaken for xterm escape code
2019-03-10T01:33:55 < englishman> works in glowingbear
2019-03-10T01:33:56 < mawk> not xterm per se but your terminal emulator understands xterm escape codes jadew 
2019-03-10T01:33:58 < mawk> like every other
2019-03-10T01:34:06 < jadew> ah, got it
2019-03-10T01:34:11 < mawk> like \033[31m for red color, etc
2019-03-10T01:34:19 < jadew> yeah

2019-03-10T02:16:49 < jadew> as far as I know, that's not a choice

2019-03-10T02:18:11 < R2COM> and you have no ground to claim him as "stupid" for this
2019-03-10T02:18:26 < R2COM> perhaps he is even smarter actually than you since he can afford it
2019-03-10T02:20:32 < jadew> sorry, but supporting someone who fucks other people and you (only as long as you're supporting her) is far from smart
2019-03-10T02:20:38 < jadew> you can get that way cheaper
2019-03-10T02:20:58 < R2COM> why you claim that she has to fuck others

2019-03-10T02:23:36 < jadew> ruined his marriage, sucked him dry of all his money and when the money was out, she was gone
2019-03-10T02:23:43 < jadew> I hope he did
2019-03-10T02:23:46 < jadew> she was hot

2019-03-10T02:55:45 < zyp> jadew, is it wrong for other people to have sex with other than you?
2019-03-10T02:56:36 < jadew> that's a question with a million answers
2019-03-10T02:57:10 < jadew> but what I can say for sure is that it's risky
2019-03-10T02:58:56 < zyp> you're thinking STDs?
2019-03-10T02:59:00 < jadew> yeah
2019-03-10T02:59:37 < zyp> well, you have a point
2019-03-10T02:59:55 < jadew> and from the perspective of the sugar daddy, is it fair that several people are eating from the same meal he's paying for?
2019-03-10T03:00:12 < jadew> I guess it could be fair, if he knew that's what he's getting into
2019-03-10T03:00:24 < jadew> but even then, you can make the argument that it's a bad deal, hence stupid
2019-03-10T03:00:35 < zyp> maybe I'm expecting too much of people but I figure nobody wants to contract and spread STDs, so I expect everybody to take care of themself
2019-03-10T03:01:05 < zyp> «eating from the same meal» sounds like bullshit
2019-03-10T03:01:32 < jadew> well, if he's supporting her way of life and other people are taking advantage of that way of life he's supporting
2019-03-10T03:01:35 < jadew> without paying
2019-03-10T03:01:42 < jadew> then... he's paying for everyone
2019-03-10T03:03:12 < jadew> it's like the worst deal you can think of when it comes to getting regular sex
2019-03-10T03:03:22 < zyp> so you argue she won't fuck those other people if the sugar daddy didn't pay?
2019-03-10T03:03:47 < jadew> if he didn't pay, he'd at least get the same deal the other guys are getting
2019-03-10T03:03:54 < jadew> which makes him less of a loser
2019-03-10T03:04:01 < zyp> I don't really see the point
2019-03-10T03:04:21 < zyp> my employer pays me to write code
2019-03-10T03:04:39 < zyp> sometimes on my free time I also write code that I contribute to opensource projects for free
2019-03-10T03:04:53 < jadew> right and if on his time you'd write code for others, for free, then would that be fair to him?

2019-03-10T03:06:35 < jadew> but I could be wrong or it could be any number of ways
2019-03-10T03:07:18 < zyp> the way I see it, the sugar daddy is paying for a service, the girl is providing the service
2019-03-10T03:07:23 < jadew> yeah, but you're trading a service

2019-03-10T03:08:07 < jadew> he can get the same deal for a fraction of the price
2019-03-10T03:08:21 < zyp> I'm not arguing he's not
2019-03-10T03:08:34 < jadew> if he's seeing it like that
2019-03-10T03:08:38 < zyp> but could he really? necessarily?
2019-03-10T03:08:40 < jadew> then yeah, it's all fair

2019-03-10T03:09:35 < zyp> yes
2019-03-10T03:09:37 < jadew> once... twice a month?
2019-03-10T03:11:21 < jadew> he can probably go to the same high end escort and only drop a couple of hundred eur/usd
2019-03-10T03:11:27 < jadew> he'd be charged by the hour
2019-03-10T03:12:02 < Cracki> the point isn't that he's paying her. the point is that he's paying immense sums when he could get that way cheaper
2019-03-10T03:12:25 < jadew> yeah, if he didn't pay her, it wouldn't be an issue at all
2019-03-10T03:12:45 < Cracki> then it'd just be an issue keeping emotions out of it
2019-03-10T03:13:35 < Cracki> "sugar daddies" are an allaround bad thing. there's no way to salvage that or rationalize it.
2019-03-10T03:14:37 < Cracki> you'll get rationalization for these broken individuals and their broken life choices mostly from western countries, who are similarly broken
2019-03-10T03:14:52 < zyp> haha
2019-03-10T03:15:48 < zyp> so you're saying that what makes it bad is the price point?
2019-03-10T03:15:53 < Cracki> no
2019-03-10T03:16:06 < Cracki> do not mistake highlighting one aspect as there being only one aspect

2019-03-10T03:16:21 < zyp> fair
2019-03-10T03:16:42 < zyp> my view regarding the price point is that it doesn't matter
2019-03-10T03:16:48 < Cracki> why doesn't it?
2019-03-10T03:17:08 < Cracki> to my mind, it obviously does. money doesn't grow on trees.
2019-03-10T03:17:26 < zyp> you can apply «why do you buy x when you can buy y for a lot cheaper?» to a lot of stuff, people still buy x
2019-03-10T03:17:50 < zyp> why do you buy mercedes when you can buy skoda? etc…
2019-03-10T03:17:50 < Cracki> then you should explain how people put value on things

2019-03-10T03:20:35 < zyp> the reason I've never bought anything there is because shit costs like ten times of what comparable stuff costs at ikea
2019-03-10T03:20:46 < Cracki> bad analogy
2019-03-10T03:21:00 < Cracki> good analogy would be you paying lots of money for something you could have cheaper
2019-03-10T03:21:07 < Cracki> for the exact same thing
2019-03-10T03:21:20 < jadew> and with a faster delivery
2019-03-10T03:21:24 < Cracki> unless you enjoy wasting money, which would put a *value* on the act of wasting it
2019-03-10T03:21:29 < jadew> and easier to get access to it
2019-03-10T03:22:02 < jadew> I think guys who do this find it easier being in a relationship like this, than actually paying a hooker

2019-03-10T03:22:05 < Cracki> paypigs enjoy losing money. I'd classify that as irrational at least, pathologic even.

2019-03-10T03:24:15 < zyp> Cracki, I'm saying that I don't get why people would want to buy furniture at that other store
2019-03-10T03:24:22 < Cracki> wait, what do cones have to do with lenses?
2019-03-10T03:24:32 < Cracki> ah right, yes, I don't get that either
2019-03-10T03:24:34 < zyp> but people still do
2019-03-10T03:24:39 < rajkosto> this shit is confusing me https://images.sshnuke.net/2019-03-10_02-24-29_KKXY3ZALk.png
2019-03-10T03:24:55 < zyp> so I figure they simply just like spending the money
2019-03-10T03:24:55 < jadew> zyp, which makes them suckers
2019-03-10T03:24:56 < rajkosto> do i focus into the 0.75mm hole or onto the die making sure the angle is 41o
2019-03-10T03:25:03 < Cracki> maybe they don't know any better, or they can't be assed to put the time in to find better offers, or they live right around the corner :>
2019-03-10T03:25:08 < Laurenceb_123> https://imgoat.com/uploads/eabe3a1649/205177.png
2019-03-10T03:25:21 < Cracki> rajkosto, what is that
2019-03-10T03:25:28 < rajkosto> light sensor with HOLE
2019-03-10T03:25:31 < R2COM> jadew why are they suckers
2019-03-10T03:25:33 < zyp> said store is five minutes away from ikea :p
2019-03-10T03:25:43 < jadew> R2COM, because they're spending more than they have to
2019-03-10T03:25:48 < Cracki> as long as it's not supposed to make a picture, just focus any way you like
2019-03-10T03:25:49 < rajkosto> to make sure the fov does not become higher than its calibrated to
2019-03-10T03:25:51 < R2COM> he makes a lot of money and wants to spend it why the hell he is sucker!
2019-03-10T03:25:55 < R2COM> LMAO
2019-03-10T03:26:00 < R2COM> who is the judge?
2019-03-10T03:26:01 < R2COM> you?
2019-03-10T03:26:06 < jadew> math
2019-03-10T03:26:09 < R2COM> no
2019-03-10T03:26:18 < R2COM> people spend 1 million dollar for a fucking PAINTING
2019-03-10T03:26:22 < zyp> I agree with R2COM here
2019-03-10T03:26:23 < R2COM> which i would not pay $500 for
2019-03-10T03:26:24 < R2COM> now what?
2019-03-10T03:26:25 < Cracki> lol
2019-03-10T03:26:26 < rajkosto> Cracki, CAN you even focus an "infinite area light 3mm away"
2019-03-10T03:26:31 < Cracki> keep going, you're funny
2019-03-10T03:26:37 < Cracki> rajkosto, uh wat
2019-03-10T03:26:41 < Cracki> show me infinite
2019-03-10T03:26:43 < jadew> if you can get X for 10 or X for 200 and you get X for 200, even tho 10 has faster delivery and easier to order, then yeah, you're a sucker
2019-03-10T03:26:55 < rajkosto> its infinite because it covers the entire opening of the lens
2019-03-10T03:27:04 < rajkosto> im sticking this thing right into the light
2019-03-10T03:27:13 < Cracki> you're overcomplicating it
2019-03-10T03:27:14 < zyp> what is the point of saving money?
2019-03-10T03:27:25 < rajkosto> i want light amplification pls
2019-03-10T03:27:29 < jadew> zyp, so you can get more stuff
2019-03-10T03:27:29 < Cracki> money grows on trees, I knew it
2019-03-10T03:27:30 < R2COM> being richest man on the cemetery
2019-03-10T03:27:37 < zyp> R2COM, exactly
2019-03-10T03:27:41 < zyp> when you're dead, you're dead
2019-03-10T03:27:46 < jadew> you could get two chicks for the price of one
2019-03-10T03:27:57 < zyp> having a lot of money isn't the goal, money is just the means
2019-03-10T03:27:59 < tjq> Perhaps you would like an 11 year old prostitute sent to your room. We can do that
2019-03-10T03:28:03 < Cracki> this is getting stupid. you aren't arguing over a terminal cancer patient.
2019-03-10T03:28:21 < zyp> Cracki, we're all gonna die at some point :)
2019-03-10T03:28:56 < R2COM> dying is just a way of getting into Valhalla
2019-03-10T03:29:04 < Cracki> rajkosto, you want a simple focusing lens. you'd put the sensor right in the focal point of the lens. then any parallel rays come out focused in that point
2019-03-10T03:29:29 < jadew> should I give you my paypal account to relieve you of those money you don't need anyway?
2019-03-10T03:29:44 < R2COM> i dont have money i dont need
2019-03-10T03:29:53 < R2COM> and you are not a hot chick with big boobs
2019-03-10T03:29:58 < R2COM> so.. .sorry 
2019-03-10T03:29:59 < rajkosto> Cracki, look at drawing in datasheet i linked
2019-03-10T03:30:04 < Cracki> rajkosto, the aperture/hole only matters for how large and far away the lens can be
2019-03-10T03:30:37 < rajkosto> it will cutoff any image that's larger than 0.75mm radius when it hits the hole
2019-03-10T03:30:40 < Cracki> lens diameter = tan(20.5 degrees) * lens distance from die
2019-03-10T03:30:56 < Cracki> and distance should be focal distance
2019-03-10T03:30:58 < Laurenceb_123> wtf is rajkosto building?
2019-03-10T03:31:04 < rajkosto> Laurenceb_123, A WEAPON TO SURPASS METAL GEAR
2019-03-10T03:31:07 < Laurenceb_123> a free space optical comms thing?
2019-03-10T03:31:14 < jadew> is that sex map real?
2019-03-10T03:31:18 < Laurenceb_123> yes
2019-03-10T03:31:26 < jadew> what is ebony?
2019-03-10T03:31:31 < Cracki> black
2019-03-10T03:31:36 < rajkosto> its not a sex map
2019-03-10T03:31:37 < Laurenceb_123> like you dont know
2019-03-10T03:31:39 < rajkosto> its porn searches by women on pornhub
2019-03-10T03:31:59 < tjq> Hyperloop
2019-03-10T03:32:10 < tjq> Or EEstor battery
2019-03-10T03:32:17 < Cracki> lenses, let's get back to lenses please
2019-03-10T03:32:27 < jadew> so... the blacks are looking for black, indians for indians, the chinese are looking for japanese porn lol
2019-03-10T03:32:42 < Cracki> that's at least related to that optical IC, which is somewhat related to programming stm32
2019-03-10T03:32:58 < Cracki> yes the chinese want what they can't have :>
2019-03-10T03:33:00 < rajkosto> Cracki, well without any lens i seem to get 1000 counts (out of 65535) for my target average light, which is super low
2019-03-10T03:33:08 < rajkosto> with a diffuser sheet somewhere in the optical path, it halves
2019-03-10T03:33:09 < jadew> Cracki, being groped in the bus?
2019-03-10T03:33:15 < Cracki> rajkosto, is that aperture circular, square, ...?
2019-03-10T03:33:18 < jadew> by a large crowd
2019-03-10T03:33:26 < zyp> jadew, they have a lot of fun statistics: https://www.pornhub.com/insights/
2019-03-10T03:33:31 < rajkosto> and it also doesnt seem to matter what distance the chip is vs the light source
2019-03-10T03:33:31 < Cracki> bus groping, that must be an interesting experience
2019-03-10T03:33:34 < rajkosto> Cracki, hole
2019-03-10T03:33:38 < jadew> zyp, that's great, thanks :D
2019-03-10T03:33:43 < Cracki> rajkosto, diffuser is silly of course
2019-03-10T03:33:58 < rajkosto> a diffuser like one of those funky sheets from a lcd monmitor
2019-03-10T03:34:03 < Cracki> distance will matter if you aren't very far away from the light source
2019-03-10T03:34:12 < rajkosto> https://images.sshnuke.net/2019-03-10_02-34-06_Bxp4yZywG.png
2019-03-10T03:34:21 < Cracki> so... circular hole, diameter 0.75mm, you calculate the area of that
2019-03-10T03:34:29 < rajkosto> distance doesnt seem to matter i can glue the thing to my monitor and its the same as being 1-3cm away
2019-03-10T03:34:31 < Cracki> then you tell me how much more light you want. that's the area of the lens you need.
2019-03-10T03:35:23 < rajkosto> distance does matter for point light sources like a high brightness LED of course but i dont care about that
2019-03-10T03:35:25 < rajkosto> just flat panels
2019-03-10T03:35:43 < Cracki> aperture is 0.44 sq.mm, so if you want 100 times more light, you want a lens with 7.5 mm diameter
2019-03-10T03:35:53 < R2COM> apex legends search on pornhub?
2019-03-10T03:35:54 < R2COM> WTF
2019-03-10T03:36:01 < rajkosto> R2COM, rule 34
2019-03-10T03:36:09 < rajkosto> last year it was FORTNITE btw
2019-03-10T03:36:37 < Cracki> so you get a lens with the right area/diameter, and then you have to figure out focal distance
2019-03-10T03:36:54 < rajkosto> Cracki, if only it was that easy
2019-03-10T03:36:58 < Cracki> it is?
2019-03-10T03:37:01 < rajkosto> its not
2019-03-10T03:37:03 < R2COM> are there stm32 searches
2019-03-10T03:37:03 < Cracki> why not
2019-03-10T03:37:29 < Cracki> the drawing shows height of whole IC, not aperture to die surface, but I guess that hardly matters
2019-03-10T03:37:32 < rajkosto> you arent taking the hole into account
2019-03-10T03:37:42 < Laurenceb_123> ^rule 34
2019-03-10T03:37:59 < Cracki> why do you think I'm not?
2019-03-10T03:38:21 < Cracki> why do you think I'm talking about focal distance?
2019-03-10T03:38:28 < rajkosto> if you focus on the hole
2019-03-10T03:38:29 < zyp> aww, searching stm32 doesn't return any results
2019-03-10T03:38:41 < Cracki> explain your confusion
2019-03-10T03:38:42 < zyp> «We're sorry, but the requested search cannot be found. Broaden your search.
2019-03-10T03:38:44 < zyp> ›
2019-03-10T03:39:13 < Cracki> it would make sense to put the hole in focus, not the die.
2019-03-10T03:40:23 < Cracki> still, lens diameter / focal length = sensor size / (distance of hole to die surface)
2019-03-10T03:40:40 < Cracki> so you cover the sensor completely, and not more
2019-03-10T03:41:43 < Cracki> if you have space constraints, you can put the focus closer to the die, as long as the aperture doesn't intersect the path of your light
2019-03-10T03:42:20 < Cracki> you need to come up with some concrete numbers
2019-03-10T03:42:35 < rajkosto> if you focus on the hole you get this https://images.sshnuke.net/2019-03-10_02-42-26_ve176wDAb.png
2019-03-10T03:42:38 < Cracki> sensor area would be the first useful one, desired "gain" being the second
2019-03-10T03:42:54 < rajkosto> the image is larger than the sensor once it reaches it, so most of it is wasted
2019-03-10T03:43:00 < Cracki> yeah so? then you pick a longer focal distance so the cone is narrower
2019-03-10T03:43:11 < Cracki> or you put the focus closer to the die, as I said
2019-03-10T03:43:30 < rajkosto> you cant do it if maintaining angle of 20.5/41
2019-03-10T03:43:36 < Cracki> wat
2019-03-10T03:43:43 < Cracki> that is irrelevant
2019-03-10T03:43:54 < rajkosto> you need to use a larger angle
2019-03-10T03:43:57 < Cracki> that's just a helpful number they give
2019-03-10T03:44:01 < rajkosto> and larger angles get cut off by the aperture
2019-03-10T03:44:08 < Cracki> dude you know geometry, you can figure this out
2019-03-10T03:44:18 -!- mirage335 [~mirage335@mirage335-base.soaringindustries.space] has quit [Ping timeout: 252 seconds]
2019-03-10T03:44:20 < rajkosto> ive figured it out and its impossible :(
2019-03-10T03:44:27 < zyp> wtf are you going on about?
2019-03-10T03:44:27 < Cracki> it sounds to me like you're just voicing objections because you haven't spent a moment of thought on it
2019-03-10T03:44:34 < Cracki> "impossible" hah
2019-03-10T03:44:45 < zyp> angle is a function of sensor size and focal distance
2019-03-10T03:44:48 < rajkosto> it violates the conservation of etendue
2019-03-10T03:45:09 < Cracki> conservation of what?
2019-03-10T03:45:31 < Cracki> only mawk is allowed to anglicize french terms
2019-03-10T03:45:39 < rajkosto> thats the only thing its called
2019-03-10T03:45:54 < mawk> I don't know what it is either
2019-03-10T03:45:58 < tjq> CIS white males invoking reality and science. Niggers are free to practice voodoo without persecution
2019-03-10T03:46:03 < mawk> étendue means spread
2019-03-10T03:46:09 < mawk> or span
2019-03-10T03:46:11 < mawk> or I don't know
2019-03-10T03:46:17 < Cracki> hmmm thank you for explaining him :P
2019-03-10T03:46:46 < Cracki> we're back to spreading things. I'm sure pornhub knows all about it.
2019-03-10T03:46:53 < mawk> lol
2019-03-10T03:47:25 < zyp> rajkosto, you'll probably want the circle to be a bit larger than the sensor anyway to avoid vigntting in the corners
2019-03-10T03:47:48 < rajkosto> i dont know how large the sensor is or how distant it is from the aperture
2019-03-10T03:48:07 < zyp> what aperture are you talking about?
2019-03-10T03:48:23 < rajkosto> https://www.mouser.co.uk/images/marketingid/2017/img/173089913.png this one
2019-03-10T03:48:42 < zyp> got the product link for that?
2019-03-10T03:48:57 < Cracki> https://i.imgur.com/Z7kIDR3.png
2019-03-10T03:49:06 < Cracki> this is the maximum angle
2019-03-10T03:49:24 < rajkosto> congrats you violated the law
2019-03-10T03:49:31 < Cracki> pick your lens diameter, put it at the minimum distance, figure focal length, done
2019-03-10T03:49:36 < Cracki> what fucking law
2019-03-10T03:49:39 < rajkosto> I AM THE LAW
2019-03-10T03:49:45 < rajkosto> the law that the angle must be 41oC
2019-03-10T03:49:51 < Cracki> there is no such law
2019-03-10T03:49:52 < Laurenceb_123> he probably means brightness conservation?
2019-03-10T03:49:53 < R2COM> rajkosto how do i disable that "hyperlink" in MSVC showing "references" when i dont ask for it inside a code
2019-03-10T03:50:25 < rajkosto> zyp, https://ams.com/as7261
2019-03-10T03:50:43 < Cracki> if you want your 41 damned degrees, then calculate with that and be done
2019-03-10T03:51:36 < Cracki> then lens diameter = 2 * tan(20.5 degrees) * focal distance
2019-03-10T03:51:54 < rajkosto> what curvature of the lens
2019-03-10T03:52:02 < Cracki> depends on focal distance
2019-03-10T03:52:12 < rajkosto> 0
2019-03-10T03:52:14 < Cracki> or do you mean "convex"
2019-03-10T03:52:20 < Cracki> now you're just trolling
2019-03-10T03:52:30 < rajkosto> focal distance == thing you are trying to take an image of, right ?
2019-03-10T03:52:33 < Cracki> do you actually mean 0 focal distance
2019-03-10T03:52:34 < Cracki> no
2019-03-10T03:52:42 < Cracki> please review lens geometry
2019-03-10T03:52:46 < zyp> you might want to read https://en.wikipedia.org/wiki/Angle_of_view
2019-03-10T03:53:00 < zyp> Cracki, I don't see how lens diameter is relevant for the FoV
2019-03-10T03:53:36 < zyp> in my understanding, lens diameter is only relevant for the aperture, as in the amount of light you let in
2019-03-10T03:53:40 < Cracki> zyp, do you think anyone related diameter to fov? I didn't.
2019-03-10T03:53:50 < Cracki> diameter only matters to how much light he wants to gather.
2019-03-10T03:53:54 < Cracki> why did you ask that?
2019-03-10T03:54:05 < Cracki> was I unclear?
2019-03-10T03:54:06 < zyp> because I'm confused
2019-03-10T03:54:13 < rajkosto> Cracki, https://images.sshnuke.net/2019-03-10_02-53-53_mSxor4HxM.png my object is infinitely close and infinitely large
2019-03-10T03:54:22 < Cracki> infinitely close means 0 distance
2019-03-10T03:54:25 < Cracki> and that's nonsense
2019-03-10T03:54:37 < Cracki> you're working with mathematical bullshit numbers
2019-03-10T03:54:45 < Cracki> you'll never get a solution like that
2019-03-10T03:55:57 < Laurenceb_123> kek he is on 4chan /pol/ again https://mobile.twitter.com/PrisonPlanet/status/1104495369138987009?p=v
2019-03-10T03:56:13 < zyp> Cracki, unless I'm misunderstanding you stated that lens diameter = blah * tan(fov/2) or something, and I don't understand how
2019-03-10T03:56:25 < Cracki> you misunderstand
2019-03-10T03:56:51 < Cracki> besides, why would that even be a question
2019-03-10T03:57:03 < zyp> so what did you actually mean?
2019-03-10T03:57:09 < Cracki> lens size scales with focal distance
2019-03-10T03:57:12 < Cracki> that's what I mean
2019-03-10T03:57:22 < Cracki> for this given problem, that's the degree of freedom
2019-03-10T03:57:31 < Cracki> not in general. I DO NOT claim this in general.
2019-03-10T03:57:37 < Cracki> people always misunderstand that.
2019-03-10T03:58:01 < zyp> why does lens size scale with focal distance?
2019-03-10T03:58:06 < Cracki> I am deliberately ignoring his insane requirements of "infinitely close, infinitely large"
2019-03-10T03:58:28 < Cracki> are you asking because you don't see the geometry or because you think I said something wrong?
2019-03-10T03:59:41 < zyp> I'm asking because it doesn't yet make sense to me
2019-03-10T03:59:43 < rajkosto> Cracki, the object is bigger than the lens and like 3mm away how about now
2019-03-10T03:59:47 < Cracki> you have a cone, right?
2019-03-10T03:59:59 < Cracki> tip of the cone is suppsoed to be focus
2019-03-10T04:00:04 < Cracki> put a lens in the cone
2019-03-10T04:00:09 < rajkosto> to collect all the light from this object that the lens can see, the angle on the other side will be HUGE
2019-03-10T04:00:11 < Cracki> size scales with focal distance
2019-03-10T04:00:24 < rajkosto> huge angles get cut off by aperture
2019-03-10T04:00:27 < Cracki> rajkosto, specify "object"
2019-03-10T04:00:33 < Cracki> explain why your object is 3mm away
2019-03-10T04:00:38 < rajkosto> because its the computer screen
2019-03-10T04:00:43 < Cracki> and...?
2019-03-10T04:00:47 < rajkosto> and im sticking the sensor right on the screen.
2019-03-10T04:01:05 < zyp> I think you're going about it the wrong way
2019-03-10T04:01:07 < Cracki> and you won't change that 3mm requirement?
2019-03-10T04:01:36 < Cracki> so you want more light... but you also want a distance of 3mm
2019-03-10T04:01:40 < Cracki> good luck with that
2019-03-10T04:01:48 < rajkosto> it really doesnt matter what the distance is because to collect more light the lens would need to be bigger, hwich means larger distance, which ends up with the same amount of light being collected
2019-03-10T04:01:53 < Cracki> I think there's no way to go about fixing bad requirements
2019-03-10T04:02:40 < zyp> Cracki, you're talking about these cones, right: https://upload.wikimedia.org/wikipedia/commons/c/cd/Cirles_of_confusion_lens_diagram.png ?

2019-03-10T04:03:10 < Cracki> if the lens would sit right on the screen surface
2019-03-10T04:03:58 < Cracki> please disengage from me, turn to him with questions. I'm done with this.
2019-03-10T04:04:23 < zyp> okay, I think I'm starting to see your point now
2019-03-10T04:04:38 < zyp> although, who the fuck cares about the angle between the sensor and the lens?
2019-03-10T04:04:41 < rajkosto> the total number of photons emitted by the surface in view increases when you move it away, but so does the total number of photons missing.
2019-03-10T04:05:09 < rajkosto> zyp, https://images.sshnuke.net/2019-03-10_03-05-07_3p77o8j2o.png
2019-03-10T04:05:11 < Cracki> simply wat
2019-03-10T04:05:55 < zyp> rajkosto, ah, okay
2019-03-10T04:06:16 < rajkosto> its calibrated for that angle, which is why they even included it on the chip
2019-03-10T04:06:29 < rajkosto> they have a non-calibrated sensor that just gives you raw values and is an exposed die in a clear coating
2019-03-10T04:06:37 < rajkosto> its many times cheaper
2019-03-10T04:08:15 < zyp> in that case what Cracki said makes total sense, choose lens diameter based on focal length
2019-03-10T04:09:50 < zyp> rajkosto, so at this point what are you uncertain about?
2019-03-10T04:10:09 < rajkosto> how to do any calculations when the object on the other side of the lens isnt an object but the entire frame
2019-03-10T04:10:21 < zyp> what sort of calculations?
2019-03-10T04:10:33 < rajkosto> like lens curvature and distance
2019-03-10T04:11:35 < zyp> what do you mean by «isn't an object»?
2019-03-10T04:12:14 < rajkosto> https://images.sshnuke.net/2019-03-10_03-12-11_ClSUQ2H4y.png ???
2019-03-10T04:12:41 < zyp> what am I looking at?
2019-03-10T04:12:57 < rajkosto> the object is always the same size as the lens and very close to it
2019-03-10T04:14:18 < zyp> why?
2019-03-10T04:14:55 < rajkosto> because its stuck to the screen and its trying to get as large of a circle of a screen to get to the sensor
2019-03-10T04:15:21 < zyp> what are you trying to do?
2019-03-10T04:15:29 < rajkosto> https://www.datacolor.com/wp-content/uploads/2016/08/Feature4-12.jpg
2019-03-10T04:16:09 < zyp> okay, so you're building a color calibrator
2019-03-10T04:16:19 < rajkosto> kinda
2019-03-10T04:16:28 < rajkosto> "why not use an existing one" need it to be controllable by my stm32 precisely
2019-03-10T04:16:53 < rajkosto> they are all super proprietary and unfriendly
2019-03-10T04:16:56 < zyp> why does the lens be as close to the screen as possible? what prevents you from adding some distance?
2019-03-10T04:17:03 < rajkosto> ok i can add distance
2019-03-10T04:17:13 < Cracki> doesn't even matter. just assume parallel light rays
2019-03-10T04:17:33 < rajkosto> dont think adding distance gets me anything
2019-03-10T04:17:46 < zyp> of course it does
2019-03-10T04:18:07 < zyp> stick your eye to the surface of the monitor and see if you can get anything in focus
2019-03-10T04:18:10 < rajkosto> is there like an online lens jiggler i can use
2019-03-10T04:18:16 < rajkosto> heh i want it to be out of focus
2019-03-10T04:18:34 < rajkosto> blur the grid in between the pixels away
2019-03-10T04:18:41 < zyp> why even bother with a lens then?
2019-03-10T04:18:54 < rajkosto> because i need a lot more light to get into the sensor than is getting into it without one

2019-03-10T04:31:35 < tjq> honestly have no idea
2019-03-10T04:32:07 < tjq> I was just thinking about a bunch of angry fat feminazis who poured their disability (obesity) pension into her
2019-03-10T04:33:45 < zyp> rajkosto, okay, I had to wrap my head around this a bit
2019-03-10T04:34:43 < zyp> if im calculating correctly, ±20.5 degrees equals f/1.3 or so
2019-03-10T04:37:32 < zyp> since all you want is to pick up the average color, you'll want to use a lens focused at infinity, and can put it all up to the monitor
2019-03-10T04:39:13 < zyp> as long as you pick a focal length and diameter relationship to give you ±20.5 degrees, you'll get f/1.3 in any case, which in traditional photography terms says you get the same amount of illumination from the same scene
2019-03-10T04:39:23 < zyp> but in your case, you won't have the same scene
2019-03-10T04:39:46 < zyp> the larger lens you pick, the more screen area it will cover and the more light it will pick up
2019-03-10T04:40:29 < rajkosto> so screen can be assumed to just be parallel rays coming from infinity ?
2019-03-10T04:40:38 < zyp> yes
2019-03-10T04:41:10 < zyp> all the rays coming straight in will then hit the center of the sensor
2019-03-10T04:42:37 < zyp> hmm
2019-03-10T04:43:49 < zyp> on the other hand, a larger lens/focal length means that less of the rays that are not coming straight in will hit the sensor
2019-03-10T04:44:28 < rajkosto> arent they all polarized and coming straight in on a screen anyway ?
2019-03-10T04:45:23 < zyp> not if you can see anything at all also when you don't look straight at it :p
2019-03-10T04:46:34 < zyp> hmm
2019-03-10T04:46:44 < rajkosto> doesnt it all average out to unity gain at the end ?
2019-03-10T04:46:44 < aandrew> zyp: how did you calculat the angle to f-stop?
2019-03-10T04:46:47 < aandrew> <-- camera stupid
2019-03-10T04:47:06 < zyp> just flipped your formula around
2019-03-10T04:47:17 < zyp> f-stop is f/D
2019-03-10T04:47:55 < zyp> so 1 / 2tan(20.5deg)
2019-03-10T04:47:55 < aandrew> ahh
2019-03-10T04:48:12 < aandrew> I just read f-stop is ratio of focal length to aperture diameter
2019-03-10T04:48:18 < rajkosto> is it 20.5 deg or 41 deg in calculations ?
2019-03-10T04:49:03 < zyp> ±20.5 deg is 2 * tan(20.5) in this case
2019-03-10T04:49:15 < zyp> 2 * tan(20.5) is different from tan(41)
2019-03-10T04:49:42 < rajkosto> degrees or radians  are supposed to be used ?
2019-03-10T04:50:41 < zyp> doesn't matter as you and the calculator agree on what you're using
2019-03-10T04:51:40 < zyp> so anyway, I'm starting to suspect lens size doesn't matter either
2019-03-10T04:52:15 < rajkosto> "The total number of photons emitted by the surface in view increases when you move it away, but so does the total number of photons missing."
2019-03-10T04:53:02 < zyp> a larger lens would catch more light, but having it longer away from the sensor would spread the light over a larger area as well, so you lose what you gain
2019-03-10T04:53:20 < rajkosto> DAS WHAT IM SAYIN
2019-03-10T04:53:27 < zyp> yes
2019-03-10T04:54:00 < rajkosto> however it eliminates the need for a diffuser
2019-03-10T04:54:47 < rajkosto> which loses half the light for me if i put it anywhere in the optical path
2019-03-10T04:54:52 < zyp> so the only way to get more light is to get a larger aperture, i.e. a lower f-stop
2019-03-10T04:55:14 < zyp> which means increasing the angle past ±20.5 degrees
2019-03-10T04:55:25 < rajkosto> which ruins the color accuracy
2019-03-10T04:55:25 < Cracki> ever roasted ants with a magnifying glass? lens size DOES matter
2019-03-10T04:55:38 < rajkosto> Cracki, your light is also infinitely away
2019-03-10T04:55:46 < Cracki> was that an objection?
2019-03-10T04:56:06 < rajkosto> youre increasing the angle by increasing your lens size but keeping the same distance from the ant
2019-03-10T04:56:23 < Cracki> you need to learn optics or trust others to solve it for you
2019-03-10T04:56:43 < rajkosto> Cracki, i apparently solved it before even asking
2019-03-10T04:56:45 < zyp> Cracki, bigger lens means bigger aperture :)
2019-03-10T04:56:54 < rajkosto> and its impossible
2019-03-10T04:56:57 < zyp> problem is rajkosto can't increase the aperture more
2019-03-10T04:57:04 < Cracki> certainly more aperture is the whole point of this exercise
2019-03-10T04:57:14 < zyp> aperture as in f-stop
2019-03-10T04:57:15 < Cracki> uh
2019-03-10T04:57:24 < Cracki> I don't believe you're figuring this right
2019-03-10T04:57:45 < Cracki> it's certainly a challenge to find a lens that's large _and_ has a short focal distance
2019-03-10T04:58:01 < zyp> did you read this part? https://images.sshnuke.net/2019-03-10_03-05-07_3p77o8j2o.png
2019-03-10T04:58:12 < zyp> that's what limits the aperture
2019-03-10T04:58:14 < Cracki> yes, which is why I need the whole data shit
2019-03-10T04:58:27 < rajkosto> the only way to get rid of the 20.5 angle limit
2019-03-10T04:58:32 < rajkosto> is to drill the hole to be bigger
2019-03-10T04:58:34 < Cracki> with some more information, one could work with/around that fucking microlens
2019-03-10T04:58:47 < rajkosto> and then you lose all the calibration
2019-03-10T04:58:52 < Cracki> that angle limit isn't a limit to how much light you can gather
2019-03-10T04:59:03 < Cracki> it's only a limit to the size of your apparatus
2019-03-10T04:59:08 < Cracki> (lower limit)
2019-03-10T04:59:25 < Cracki> kek you want calibration?
2019-03-10T04:59:28 < rajkosto> im goin mental here
2019-03-10T04:59:31 < rajkosto> Cracki, its already calibrated
2019-03-10T04:59:38 < Cracki> you think you're getting calibrated values with a huge fucking lens in front of it?
2019-03-10T04:59:46 < rajkosto> yes ;)
2019-03-10T04:59:59 < Cracki> color values will probably stay the same, but you ARE getting more photons
2019-03-10T05:00:07 < rajkosto> try it.
2019-03-10T05:00:25 < rajkosto> photons get lost to the void
2019-03-10T05:00:39 < Cracki> I'm starting to doubt your ability to grasp this
2019-03-10T05:00:51 < rajkosto> its the same reason its getting the same amount of photons when its right stuck to the screen vs some centimeters away
2019-03-10T05:00:59 < Cracki> nah
2019-03-10T05:01:02 < zyp> I agree with rajkosto here
2019-03-10T05:01:21 < Cracki> "stuck to screen" and "some centimeters away" is nothing
2019-03-10T05:01:48 < Cracki> that's how light works
2019-03-10T05:02:06 < Cracki> a white wall is the same brightness, no matter if you have your eyeball almost up to it, or you're standing meters away
2019-03-10T05:02:24 < rajkosto> now youre gettin it
2019-03-10T05:02:32 < Cracki> no, you misunderstand me again
2019-03-10T05:02:54 < Cracki> ray optics are simple but not as simple as everyone thinks
2019-03-10T05:02:56 < rajkosto> now add an aperture in front of your eye
2019-03-10T05:03:07 < Cracki> look into the equations people need to deal with for photon mapping
2019-03-10T05:03:15 < rajkosto> not only will brightness be the same, but total photon count will  be the same
2019-03-10T05:03:39 < Cracki> you're forgetting that lenses are involved
2019-03-10T05:04:05 < Cracki> anyway, I think your project is just not possible for you
2019-03-10T05:04:09 < rajkosto> all the lenses will do is focus/defocus, which doesnt matter for this exercise
2019-03-10T05:04:20 < Cracki> wrong
2019-03-10T05:04:43 < Cracki> https://ricktu288.github.io/ray-optics/
2019-03-10T05:05:07 < Cracki> if that doesn't fix your intuition, nothing will
2019-03-10T05:05:17 < zyp> Cracki, a photo of a white wall taken at a 1m distance will also be the same brightness whether taken with a 18mm f/2.8 lens or a 200mm f/2.8 lens, even if the latter photo contains a much smaller piece of the wall surface
2019-03-10T05:05:32 < Cracki> again, f-stops, I don't follow
2019-03-10T05:05:56 < Cracki> before I go along with any of that f-stop stuff you'd have to explain it to me so I understand
2019-03-10T05:06:28 < zyp> like I said, it's f/D, i.e. focal length / aperture diameter
2019-03-10T05:06:37 < Cracki> besides, I suspect you're stating things I'm not even disputing
2019-03-10T05:06:47 < Cracki> so it's beside the point to discuss that
2019-03-10T05:06:47 < rajkosto> on that website
2019-03-10T05:06:49 < rajkosto> how do i use real units
2019-03-10T05:07:01 < rajkosto> and move objects exactly
2019-03-10T05:07:13 < Cracki> try not
2019-03-10T05:07:52 < zyp> Cracki, so you're disputing my argument, but not the points I back it up with?
2019-03-10T05:08:03 < Cracki> zyp, it appears to me that "f-stops" are a measure of the solid angle

2019-03-10T05:38:24 < rajkosto> so where do i find a f1.3 lens
2019-03-10T05:47:03 < rajkosto> what type of lens btw, convex, plano-convex ?

2019-03-10T15:26:40 < Adluc> or generally such circular connectors
2019-03-10T15:41:20 < jpa-> if you are going to have the same signals as PMOD connectors, just use the same numbering?
2019-03-10T15:41:44 < jpa-> it's not like many people run SPI/UART/I2C over such connectors, usually it's RS485 or similar

2019-03-10T16:38:16 < zyp> I'd say look at where other pinouts are placing ground at least

2019-03-10T21:02:39 < qyx> it depends on adc clock freq, sampling time, etc.
2019-03-10T21:02:51 < qyx> the maximum samples per second is mentioned in the datasheet

2019-03-10T21:08:09 < Cracki> I'm sure all that is written somewhere in the RM or data sheet
2019-03-10T21:08:14 < rajkosto> but the integrator is not linear so you must make sure your input signal doesnt change faster than your sampling time ?
2019-03-10T21:09:05 < Cracki> wrong, that's what the sampling circuit does
2019-03-10T21:09:13 < Cracki> sample and hold
2019-03-10T21:09:21 < Cracki> pls there is TONS of stuff written on this
2019-03-10T21:10:24 < mawk> what's a non-linear integrator
2019-03-10T21:11:09 < Cracki> I suspect it's his confusion
2019-03-10T21:11:39 < Cracki> he's just stringing words together
2019-03-10T21:11:54 < rajkosto> just cuz you dont understand them doesnt mean its nonsense
2019-03-10T21:11:59 < rajkosto> same as yesterday
2019-03-10T21:12:04 < mawk> but an integrator is linear
2019-03-10T21:12:11 < qyx> wut integrator
2019-03-10T21:12:19 < mawk> any integrator
2019-03-10T21:12:20 < qyx> there is a few picoF sampling cap
2019-03-10T21:12:28 < qyx> the exact value is in the ds
2019-03-10T21:12:33 < qyx> there is also an AN
2019-03-10T21:12:42 < qyx> describing "getting best accuracy results using stm32 ADC"
2019-03-10T21:12:49 < qyx> there is some useful information
2019-03-10T21:12:55 < mawk> with L1 but yeah DisruptiveNL 
2019-03-10T21:12:57 < mawk> I set it up at least
2019-03-10T21:13:02 < mawk> but did not go very far
2019-03-10T21:13:07 < qyx> how to drive the ADC, how to compute errors, etc.
2019-03-10T21:13:50 < DisruptiveNL> Oke... I have some config which seems good... (taken from STM32F4) but when I want to add USART all good to shit
2019-03-10T21:14:13 < Cracki> you guys let yourselves get run around from his nonsensical prompts
2019-03-10T21:14:23 < qyx> rajkosto: higher sampling time eg. allows you to use higher impedance inputs

2019-03-10T22:59:53 < Cracki> knife with single-handedly lockable blade?
2019-03-10T23:00:05 < Cracki> maybe lockable, maybe something else
2019-03-10T23:00:31 < PaulFertser> Cracki: lockable as in something that locks into place, right? So a knife that can be open but has no mechanical locks/fixtures to hold the blade open is not included?
2019-03-10T23:00:32 < Cracki> arrestable perhaps, if anyone understands that
2019-03-10T23:00:40 < Cracki> can't tell from the word
2019-03-10T23:00:50 < Cracki> might be an actual lock, or might be a screw you can tighten, no clue
2019-03-10T23:00:56 < Cracki> pics or gtfo ;)
2019-03-10T23:01:16 < PaulFertser> It's a quote from German knife law :)
2019-03-10T23:01:21 < Cracki> ah that
2019-03-10T23:01:37 < Cracki> yes, the issue there is knives that can snap shut are unsafe
2019-03-10T23:02:00 < Cracki> pocket knives usually don't have any locking mechanism
2019-03-10T23:02:22 < PaulFertser> And so are they legal even if you can open them single-handedly?
2019-03-10T23:02:23 < Cracki> at least the ones I know don't
2019-03-10T23:02:30 < Cracki> uh you misunderstand
2019-03-10T23:02:41 < Cracki> perhaps show me more context
2019-03-10T23:02:49 < Cracki> I will refuse to read tea leaves

2019-03-10T23:03:18 < PaulFertser> Cracki: https://www.bka.de/SharedDocs/FAQs/DE/Waffenrecht/waffenrechtFrage03.html
2019-03-10T23:03:40 < Cracki> fuehrverbot means forbidden to carry
2019-03-10T23:03:50 < Cracki> german weapons law distinguishes between carrying and owning
2019-03-10T23:04:06 < Cracki> you can own a lot of stuff as long as it doesn't leave private property
2019-03-10T23:04:13 < BrainDamage> are you going to germany?
2019-03-10T23:04:22 < Cracki> and if you transport it, you have a bunch of regulations
2019-03-10T23:04:25 < PaulFertser> Yes, but my question is whether there's any distinction for carrying foldable knives with and without locking blade.
2019-03-10T23:04:44 < Cracki> the wording needs some parsing
2019-03-10T23:04:56 < Cracki> I'm not sure what they *contrast* single-handedly lockable knives *against*
2019-03-10T23:05:14 < Cracki> maybe they want you to have to use both hands to operate it, maybe not, has to be deciphered
2019-03-10T23:05:42 < Cracki> that page explains very little... unfortunate
2019-03-10T23:06:06 < PaulFertser> Good FAQ...
2019-03-10T23:06:24 < Cracki> ah, Einhandmesser can be sprung open singlehandedly. if you need a second hand to open it, it's safer.
2019-03-10T23:07:03 < PaulFertser> Yes, but my question is about locking the blade in the open state.
2019-03-10T23:07:09 < Cracki> parsing
2019-03-10T23:08:48 < Cracki> when in doubt, send a picture of what you want to carry to some authorities
2019-03-10T23:09:05 < rajkosto> PaulFertser, knife with a blade that you can fix in position with only one hand
2019-03-10T23:09:15 < Cracki> their FAQ is real shit
2019-03-10T23:10:00 < PaulFertser> rajkosto: so a knife that can't be fixed at all is apparently legal to be carried, right?
2019-03-10T23:10:12 < Cracki> even the law itself uses this coded language
2019-03-10T23:11:53 < Cracki> it appears to me that they consider _lockable_ folding knives more dangerous because you can just slash and stab with them, without regard for your own fingers
2019-03-10T23:12:34 < PaulFertser> And that makes sense actually.
2019-03-10T23:12:56 < Cracki> it's all very convoluted
2019-03-10T23:13:20 < Cracki> some site says a 10cm fixed knife is good but 4.7cm foldable and lockable is bad
2019-03-10T23:13:41 < PaulFertser> The law doesn't talk about 10cm at all though?
2019-03-10T23:13:45 < Cracki> examples
2019-03-10T23:14:24 < PaulFertser> 4.7cm foldable, lockable _and_ something you can open single-handedly is bad.
2019-03-10T23:14:52 < Cracki> just talk to someone who is an expert in this
2019-03-10T23:15:02 < rajkosto> jacknifes that you can open with only one hand are forbidden in germany
2019-03-10T23:15:04 < Cracki> or don't get caught :P
2019-03-10T23:15:42 < PaulFertser> I thought you guys know your laws ;)
2019-03-10T23:16:27 < Cracki> a lot of the motivation behind this stuff is forbidding the weapons that subhumans carry
2019-03-10T23:16:38 < Cracki> anything you can hide in a pocket yet use effectively in a fight
2019-03-10T23:17:16 < Cracki> my country isn't fucked enough yet that I would bother being versed in weapons law
2019-03-10T23:17:39 < Cracki> a friend of mine's brother got beat up by a dozen arabs/turks last weekend
2019-03-10T23:17:59 < Cracki> now they consider carrying legal pepper spray
2019-03-10T23:18:14 < Cracki> there's very little you are allowed to defend yourself with around here
2019-03-10T23:18:54 < Cracki> police with (semi?)-automatic weapons standing guard around christmas markets...
2019-03-10T23:19:23 < Cracki> if they'd just shoot those fuckers at the nonexistent border, we wouldn't have to have all that shit INSIDE our country
2019-03-10T23:19:33 < PaulFertser> Can you get a handgun licence?
2019-03-10T23:19:39 < Cracki> no.
2019-03-10T23:19:58 < Cracki> not even most security jobs have a justification for getting that.
2019-03-10T23:20:26 < PaulFertser> How about non-lethal (rubber shots) guns?
2019-03-10T23:20:37 < Cracki> what you can get is rifles and stuff for sport, which you may only use on private property
2019-03-10T23:20:54 < Cracki> there's a way you can carry gas pistols
2019-03-10T23:20:56 < Cracki> no projectiles
2019-03-10T23:21:06 < Cracki> those are quite useless tho
2019-03-10T23:21:19 < Cracki> you'd have to shoot someone point blank to cause any damage
2019-03-10T23:22:11 < Cracki> this country is obviously emasculated. that's why we have so much rape and murder of natives by foreigners
2019-03-10T23:22:35 < Cracki> if we were allowed to defend ourselves, we wouldn't look like such easy targets
2019-03-10T23:22:57 < kakimir> what country?
2019-03-10T23:23:00 < Cracki> personally, I'd go for an electro shocker, not a taser
2019-03-10T23:23:08 < Cracki> tasers are forbidden anyway
2019-03-10T23:23:26 < PaulFertser> Knives are not really useful for self-defense anyway it seems.
2019-03-10T23:23:54 < Cracki> they're useful if you want to take the other dude down while you're about to die anyway
2019-03-10T23:24:09 < Cracki> they ALWAYS attack in groups
2019-03-10T23:24:13 < Cracki> you are powerless against groups
2019-03-10T23:24:24 < Cracki> germans have been brainwashed against sticking together
2019-03-10T23:25:02 < Cracki> the most redpilled ones around here are foreigners and halfbreeds because nobody dares lecture them about original sin
2019-03-10T23:25:54 < Cracki> the most satisfying part of all this shit is that those fucking idiots who stood at the train stations clapping while those invaders came, they get knifed and raped now
2019-03-10T23:26:08 < Cracki> anyone with an ounce of brains stays the fuck away from the enrichment
2019-03-10T23:27:14 < Cracki> this "article" looks like it's a bit more thorough: http://www.taschenmesser.de/fuehrungsverbot/
2019-03-10T23:27:59 < Cracki> they probably don't even consider knives you can open singlehandedly but not lock... that'd imply a loose enough blade that it's almost flopping around
2019-03-10T23:29:02 < Cracki> transport in a bag is alright too because you can't draw within a second
2019-03-10T23:29:28 < Cracki> Ein Tortenmesser mit einer langen Klinge darf ruhig für ein Picknick im Park genutzt werden.
2019-03-10T23:29:52 < Cracki> you're allowed to knife-rape your pie
2019-03-10T23:31:01 < kakimir> history of our age will be interesting
2019-03-10T23:31:07 < Cracki> it's a good idea to carry a box cutter knife
2019-03-10T23:31:50 < Cracki> dangerous enough to slash at someone's neck, not sturdy enough to stab them in the heart
2019-03-10T23:32:23 < Cracki> hm, maybe even that's illegal :>

2019-03-10T23:36:32 < Cracki> show me numbers
2019-03-10T23:36:38 < Cracki> you're being deceptive
2019-03-10T23:36:39 < Getty> i don't need to show you the numbers if you make up claims

2019-03-10T23:37:17 < Getty> see, the first thing to start a fascist regime is denying that there is any reality in what we see.

2019-03-10T23:37:34 < Cracki> up is down, it's always the same with these bolsheviks
2019-03-10T23:37:34 < Getty> most germans learned that concept already very early, and those numbers are indeed facts, coming from the government
2019-03-10T23:37:49 < Getty> it is also kinda weird that we have the highest income years of our history with all those "problems" you state
2019-03-10T23:37:49 < Cracki> oh boy
2019-03-10T23:38:03 < Getty> you can see that we are one of the rare countries that actually has income, even very big

2019-03-11T00:25:20 < R2COM> but its also DSI_CK_P pin for DSI
2019-03-11T00:26:43 < mawk> electro-shocker is bad Cracki , you have to be very close and it doesn't work over leather; knives are bad too, they will hurt you with it if you're not a master ninja; pepper spray is bad because of the wind; peper gel is better, and you can have pepper gel guns that throw the gel at 200km/h against all possible wind, getting under any eye protection of any sort; another possibility is rubber bullet guns but they have terrible aim and you can't legally carry them 
2019-03-11T00:26:43 < mawk> on the street; better gen a rubber bullet rifle that will aim way better and is more dissuasive, you can saw off some part of the barrel to shorten it down

2019-03-11T00:37:14 < mawk> which is the only thing legal without a sports shooting license here
2019-03-11T00:37:26 < mawk> you still need to get a certificate from a doctor saying you're not crazy and register the gun with the police
2019-03-11T00:37:29 < R2COM> so get sports shooting license and be done with it
2019-03-11T00:37:38 < mawk> it's hard to get

2019-03-11T00:37:57 < mawk> and still you can't carry the gun on the streets, and you need to keep it at home unloaded in a locked safe at all times

2019-03-11T00:38:16 < mawk> and bullets can't be stored with the gun

2019-03-11T00:41:01 < R2COM> no, its all myth
2019-03-11T00:41:12 < R2COM> it is a gas piston system, which surely helps against water
2019-03-11T00:41:32 < R2COM> but AR15 also resistant to water
2019-03-11T00:41:39 < R2COM> unless you submerge it and then fire
2019-03-11T00:42:08 < R2COM> since AR15 is a direct impingement weapon, gas operated. but AK is piston operated so piston "seals" internals from outside water
2019-03-11T00:42:22 < R2COM> but there are gas piston versions of AR too, like M416

2019-03-11T03:24:50 < enh> That MCU can handle the CAN bus without the need for another IC?
2019-03-11T03:25:43 < englishman> no they will need a phy
2019-03-11T03:25:58 < bitmask> thought building one would be fun and help me learn more analog stuff, but I may just buy one, just wanted to figure out some options before I decide
2019-03-11T03:29:37 < enh> What is a phy, englishman?
2019-03-11T03:30:07 < englishman> with can, a transceiver, something to drive the actual canbus signals

2019-03-11T03:32:06 < Laurenceb_123> olimex probably make something
2019-03-11T03:32:11 < Laurenceb_123> if you trust olimex...

2019-03-11T05:18:50 < dongs> without rgb cancer
2019-03-11T05:21:37 < R2COM> thats right this rgb shit looks like gay flag inside my PC case
2019-03-11T05:22:17 < R2COM> but i bought this cuz of triple fans
2019-03-11T05:22:40 < friendofafriend> Pfffft, I've got a pride flag for a keyboard and mouse, too.
2019-03-11T05:22:57 < R2COM> so this shit really kicks, games which before gave 20FPS @ 4k/all ultra settings, now they give 45FPS and playable @ 4k
2019-03-11T05:23:31 < friendofafriend> What's the refresh on your display?
2019-03-11T05:23:37 < R2COM> 60 of course
2019-03-11T05:27:13 < tjq> alright younes RTX2080
2019-03-11T05:27:17 < tjq> get it? naa?
2019-03-11T05:27:19 < tjq> yea?
2019-03-11T05:27:51 < rajkosto> imagine playing games at only 45fps lol
2019-03-11T05:28:23 < dongs> all my shit plays at 60 on 2080 but i only play minecraft and apex
2019-03-11T05:28:44 < rajkosto> imagine sacrificing framerate for resolution in a shooter
2019-03-11T05:28:59 < R2COM> well, i tested demanding game with all shadow/water ultra setting and "12km" viewdistance in ArmA 3
2019-03-11T05:29:22 < R2COM> it was my testbench, i can slow down on some shadow shit etc
2019-03-11T05:29:24 < R2COM> and get it 60
2019-03-11T05:29:53 < R2COM> but honestly 45 is very playable
2019-03-11T05:30:16 < R2COM> depending on game... 
2019-03-11T05:30:22 < R2COM> in stuff like CSGO you want MAX
2019-03-11T05:30:30 < R2COM> but there ill have like 180FPS...
2019-03-11T05:31:07 < R2COM> shooters are different
2019-03-11T05:31:22 < R2COM> in ArmA 3 100FPS wont be big deal
2019-03-11T05:31:38 < R2COM> but in dynamic shooters like BF/CSGO it matters more (action like shooters)
2019-03-11T05:41:03 < R2COM> dongie what are you working on

2019-03-11T05:46:45 < dongs> but whatever chink stuff its all same anyway
2019-03-11T05:46:45 < R2COM> with dsi?
2019-03-11T05:46:48 < dongs> yeah
2019-03-11T05:47:00 < R2COM> you already used dsi with stm32?
2019-03-11T05:47:24 < dongs> but i only used dsi shit with 1920 and 2560x panels and those weer all novatec
2019-03-11T05:47:34 < dongs> nah stm graphics is uselses lol
2019-03-11T05:49:14 < R2COM> not useless its 720p 30hz max
2019-03-11T05:49:30 < dongs> nobody even makes a 720p dsi panel
2019-03-11T05:49:33 < dongs> like literally noone
2019-03-11T05:49:42 < dongs> they're all gonna be way more expensive than 1080p or 2560
2019-03-11T05:49:46 < R2COM> well this is more like for talking to small control type touch panels
2019-03-11T05:49:49 < R2COM> via dsi interface
2019-03-11T05:49:55 < dongs> where RGB works just fine
2019-03-11T05:50:08 < R2COM> i mean this is all about pin reduction mainly
2019-03-11T05:50:25 < R2COM> ltdc-->dsi--->low pin connecto to small panel
2019-03-11T05:52:51 < dongs> well youre already routing out of a bga
2019-03-11T05:52:55 < dongs> so that doesnt amtter
2019-03-11T05:53:03 < dongs> and you have like 2 vendors for 720p DSI panels
2019-03-11T05:53:10 < dongs> vs like 234782394792837 vendors for 16/24bit rgb panels
2019-03-11T05:54:19 < R2COM> well no if one uses lots of stuff from that BGA you can run out of pins
2019-03-11T05:54:29 < R2COM> and if you just control 4 or 7" panel?
2019-03-11T05:54:39 < dongs> then you probly can just use SPI mode anyway
2019-03-11T05:54:40 < R2COM> and XGA resolution is enough for you
2019-03-11T05:54:47 < dongs> shrug
2019-03-11T05:54:56 < R2COM> well yea..
2019-03-11T05:55:11 < dongs> 16bit rgb is not THAT many pins
2019-03-11T05:55:22 < dongs> 16+like 3-4 for signalling?
2019-03-11T05:55:30 < dongs> so 20 vs like 6 pins for DSI
2019-03-11T05:55:48 < R2COM> yesa
2019-03-11T05:56:17 < dongs> nyway i dont think STM is very suitable for industrial control type shit with a full frame rate / full size screen
2019-03-11T05:56:25 < dongs> at that point you might as well use some cheap chink SoC
2019-03-11T05:56:29 < dongs> the price will be same
2019-03-11T05:56:37 < dongs> high end F7s are way too expensive
2019-03-11T05:56:58 < R2COM> $11 
2019-03-11T05:56:59 < R2COM> ?
2019-03-11T05:57:12 < R2COM> thats the price
2019-03-11T05:57:30 < dongs> yeah, chinese SoC *with* ddr and pmic is less than tha total
2019-03-11T05:57:48 < R2COM> oh
2019-03-11T05:57:58 < R2COM> its most like ~$16
2019-03-11T05:59:04 < R2COM> yeah i guess that makes sense.. stm32f7 high end has its own place still
2019-03-11T05:59:36 < R2COM> with many different peripherals/IOs required, + 7" TFT with DSI and if price +/-~$3 doesnt matter and one already knows this platform .... then it will make sense
2019-03-11T06:00:01 < dongs> people are spoiled cunts these days, they see a color screen, they will expect assdroid or ios-levels of 'flashiness'
2019-03-11T06:00:11 < dongs> when they see a dumb square GUI with no transitions/fading/etc

2019-03-11T06:00:34 < R2COM> yes

2019-03-11T13:18:12  * karlp pulls hteblanket off his crystal ball
2019-03-11T13:27:50 < sklv> apologies, i meant to append a link then got distracted - this is the repo https://github.com/dword1511/stm32-vserprog
2019-03-11T13:29:47 < jpa-> https://github.com/dword1511/stm32-vserprog/blob/master/pcb/v3/sch.pdf  here?
2019-03-11T13:31:06 < karlp> (why do you even want to use that?)
2019-03-11T13:31:50 < jpa-> (why not? it's to program serial eeproms)
2019-03-11T13:32:03 < sklv> i thought that was for their custom pcb but it makes sense the pinout would be the same for bluepill
2019-03-11T13:32:10 < karlp> oh, it's for flashrom
2019-03-11T13:32:15 < sklv> i want to use it because i don't want to risk frying my expensive ass BBB
2019-03-11T13:32:41 < sklv> thanks
2019-03-11T13:33:56 < qyx> bbb = beagleboneblack?
2019-03-11T13:34:52  * karlp wishes mor epeople would test their websites with 400ms delay on requests.
2019-03-11T13:35:11 < karlp> my bank isn't combinign all their js, so it's ~40 requests or something
2019-03-11T13:35:25 < qyx> are there long cables to iceland?
2019-03-11T13:35:40 < karlp> no, I'm in australia, doing icelandic banking.

2019-03-11T13:35:52 < karlp> though my australian bank when I'm in iceland isn't much better.

2019-03-11T13:45:17 < sklv> qyx: yes bbb = beaglebone black
2019-03-11T13:49:57 < karlp> hrm, ok, 3 days to sort out letsencrypt shit when I get back.
2019-03-11T13:52:27 < jadew> what's there to sort about it?
2019-03-11T13:52:46 < jadew> you're not using it with their automated shit?
2019-03-11T13:52:52 < karlp> they deprecated the way I was using.
2019-03-11T13:53:02 < karlp> and now I need to automate dns text entries every blah days
2019-03-11T13:53:24 < jadew> hmm, you can validate differently
2019-03-11T13:53:37 < karlp> yes. but not the way I was.
2019-03-11T13:53:38 < dongs> hm my pal was bitching something about txt dns stuff
2019-03-11T13:53:38 < jadew> I think there's a way to validate ownership by having a special folder
2019-03-11T13:53:43 < karlp> and the other way that's allowed is by using hte .well-knonw
2019-03-11T13:53:47 < jadew> (easier than using the DNS method)
2019-03-11T13:53:54 < jadew> yeah, with that folder
2019-03-11T13:53:57 < karlp> which requires having a website publically available on that name
2019-03-11T13:54:06 < karlp> which is shock horror, not always actually useful or feasible.
2019-03-11T13:54:33 < karlp> dns is fine too, they hav ea plugin for my dns host for certbot
2019-03-11T13:54:36 < karlp> just not packaged for me.
2019-03-11T13:54:40 < karlp> just a fucking hassle
2019-03-11T13:56:39 < jadew> I think DHL is screwing with me again
2019-03-11T13:57:00 < jadew> they were supposed to deliver my boards today, but I see no update in the tracking info
2019-03-11T13:57:13 < jadew> the package is already here and went through customs

2019-03-11T14:23:32 < jadew> did you guys know about vcpkg?
2019-03-11T14:23:53 < jadew> it's a library manager for VC
2019-03-11T14:24:12 < jadew> so if you need libwhatever, you just say vcpck install whatever
2019-03-11T14:24:23 < jadew> then you can proceed to include the header file and it works
2019-03-11T14:24:36 < karlp> VC?
2019-03-11T14:24:43 < jadew> handles dependencies and all that
2019-03-11T14:24:51 < jadew> visual studio's c/c++
2019-03-11T14:25:00 < jadew> works on linux too from what I understand
2019-03-11T14:25:00 < karlp> why the fuck would it need itð's _own_ packager?
2019-03-11T14:25:20 < jadew> so you don't have to pick all the pieces yourself
2019-03-11T14:25:36 < jadew> some packages require you to have 20-30 other shit available first
2019-03-11T14:25:48 < karlp> well, fuck windows then.
2019-03-11T14:25:49 < jadew> this takes care of all those dependencies
2019-03-11T14:26:03 < jadew> karlp, those are usually opensource packages

2019-03-11T15:49:38 < jadew> aandrew, don't know... seems like a great tool to me
2019-03-11T15:50:11 < jadew> instead of having to manually install and keep track of all the libraries my own library depends on, I can just run a script that installs them all using this tool
2019-03-11T15:50:20 < jadew> then I can proceed to compiling
2019-03-11T15:50:56 < jadew> and I don't even have to care about install paths

2019-03-11T15:55:23 < qyx> did you mess with cpu2?
2019-03-11T15:56:16 < zyp> yeah, I tried turning off security (which should implicitly mass erase the flash)
2019-03-11T15:57:10 < zyp> seems like security might be forced on, but mass erase might still have gone through, killing the blob that would load encrypted firmwares
2019-03-11T16:00:11 < qyx> so now you have an empty flash with security still on
2019-03-11T16:00:32 < qyx> mhm
2019-03-11T16:00:47 < zyp> I suspect that might be the case, yes
2019-03-11T16:00:47 < qyx> even the loader is gone?
2019-03-11T16:01:04 < zyp> kinda hard to tell since I still don't get to read out that flash area
2019-03-11T16:01:39 < qyx> what if the loader is still there and just the keys have been erased to 0xff

2019-03-11T17:31:08 < jadew> that's going to screw so many people...
2019-03-11T17:31:25 < BrainDamage> there's a hard set date of 29 march
2019-03-11T17:31:32 < BrainDamage> if they don't do anything, they leave
2019-03-11T17:31:39 < jadew> oh, really, so this month?
2019-03-11T17:31:42 < BrainDamage> they have the power to request a delay
2019-03-11T17:31:51 < jadew> any ideas on what deals have been made, if any?
2019-03-11T17:31:55 < BrainDamage> none
2019-03-11T17:32:04 < BrainDamage> all so far have been refused
2019-03-11T17:32:45 < BrainDamage> if they hit the date, it'd be a 'no deal' exit, which means that uk is effectively out of EU the 30th
2019-03-11T17:33:18 < BrainDamage> if they approve deals, they can stay for some fields, or further delay severing some ties
2019-03-11T17:33:30 < BrainDamage> but as it is, if they do nothing, it'll be a clean cut
2019-03-11T17:33:53 < jadew> that's gonna suck
2019-03-11T17:34:27 < jadew> they'll have to lower their prices by at least %20 on their exports within the EU, only to stay competitive
2019-03-11T17:34:32 < BrainDamage> it's going to suck for a lot of people, eg immigrant workers in the UK, or emigrant workers outside
2019-03-11T17:35:01 < BrainDamage> individual countries have reassured that they'll keep the same priviledges even in the case of a hard exit ( italy for example )
2019-03-11T17:35:12 < BrainDamage> but that boils to the goodwill of the individual government
2019-03-11T17:35:16 < jadew> yeah, those guys are in a tough position too, but if they're already there, I guess their situation could be improved somehow

2019-03-11T20:44:58 < Steffanx> good evening jpa-. In your bike controller you do FOC. You only control Iq/torque corrent and not the direct current. You just assume its 0 or do i just miss something?
2019-03-11T20:45:03 < PaulFertser> jpa-: ok, thank you. They seem to be spending much time considering it when in fact you could probably solve their issue in an hour, heh.

2019-03-11T20:45:50 < PaulFertser> Also, I guess you could still share some details like "guys do not forget to set bit X when Y mode is used because X in the ST docs stands for _that_obscure_thing_, not the one you thought"
2019-03-11T20:46:46 < jpa-> PaulFertser: well, i wouldn't

2019-03-11T20:48:17 < PaulFertser> In some cases, I can agree, in some others, ##stm32 regulars might benefit from your new experience. Depends on the specifics I guess.
2019-03-11T20:48:28 < jpa-> Steffanx: direct current? how's that different from torque current?

2019-03-11T20:51:13 < Laurenceb> muh i2c driver
2019-03-11T20:51:20 < Laurenceb> only useful codez I ever wrote
2019-03-11T20:51:24 < jpa-> Steffanx: basic logic is that magnetic field equals current through coils; only magnetic field at 90deg angle from rotor does useful work, so that's the direction it should keep the field; and strenght of current directly determines the strength of field and thus torque
2019-03-11T20:51:54 < Steffanx> Yeah, but in the theory you often see they control both using some pi(d) controller. like https://www.roboteq.com/images/article-images/how-to/image012.png
2019-03-11T20:54:02 < jpa-> ah, flux current; that's not any more DC than the other, but it is at 0deg angle; it gives no torque, but it can be used to 1) provide magnetic field in rotor for non-permanent-magnet induction motors or 2) cancel part of the permanent-magnet field to achieve larger speeds
2019-03-11T20:54:29 < jpa-> i just use complex numbers so that is handled by the same PID
2019-03-11T20:54:57 < Steffanx> hm
2019-03-11T20:55:07 < Laurenceb> holy shit this guy is actually funny
2019-03-11T20:55:11 < jpa-> https://github.com/PetteriAimonen/ebike-controller/blob/master/src/motor_control.c#L93    reference = I * torque_current    makes the flux current zero, but it could be   reference = I * torque_current + flux_current
2019-03-11T20:55:20 < Laurenceb>  7:20 for teh lulz
2019-03-11T20:57:00 < Steffanx> Thank you jpa-, ill go back and look at it a bit more :)
2019-03-11T20:57:19 < srk> jpa-: sounds like FOC
2019-03-11T20:57:26 < jpa-> srk: .. because it is FOC?
2019-03-11T20:57:58 < srk> :)
2019-03-11T20:58:34 < jpa-> Steffanx: FOC was really difficult to understand at first, but really the point is just to do PID control in rotating frame, so that the current / voltage vectors stay relatively constant and are easy to control - without the transform, they would vary so fast that PID wouldn't keep up
2019-03-11T20:58:42 < Steffanx> Did i make it to srk ignore list or did he just miss the initial question?

2019-03-11T21:03:46 < Laurenceb> illuminati did brexit
2019-03-11T21:04:10 < jpa-> Steffanx: yeah, once you finish your FOC servo controller for steppers, please share

2019-03-11T21:04:42 < Steffanx> wut
2019-03-11T21:04:44 < jpa-> it should work very much the same for steppers, just the transform is easier because you just take real and imag part directly

2019-03-11T21:05:42 < srk> dunno, the guy told me you need faster phase measurements and control
2019-03-11T21:05:57 < srk> with some crazy high ppr encoders
2019-03-11T21:06:23 < jpa-> it all depends on the target RPM / step rate
2019-03-11T21:06:37 < Steffanx> Step rate will be extremely low for me
2019-03-11T21:06:52 < Steffanx> nah relatively low :P
2019-03-11T21:08:25 < jpa-> something like ~10 samples per one full step should be plenty, and it will rotate ok with even just 2 samples per full step
2019-03-11T21:09:38 < jpa-> high PPR encoders are good if you want sub-step resolution position control, but if the point is just to get the acoustic & torque advantages of FOC, whatever resolution is enough for the application is plenty
2019-03-11T21:10:03 < tjq> hmm
2019-03-11T21:10:07 < jpa-> (and nothing stops connecting very high PPR encoders to STM32 timers also, or use sin/cos encoders and connect using ADC)

2019-03-11T21:13:04 < Steffanx> its a stepper with "integrated" encoder > 100 euro bucks iirc
2019-03-11T21:13:46 < jpa-> Steffanx: for me, 168 MHz F4 was enough to run control loop at ~25kHz, though i scaled back to 10kHz to have some slack - but that is just because i was lazy and used the complex.h functions directly which aren't particularly optimized
2019-03-11T21:13:52 < Steffanx> aliexpress mr tjq
2019-03-11T21:13:59 < jpa-> using e.g. sin/cos lookup table would be much faster
2019-03-11T21:14:08 < tjq> aliexpress :\
2019-03-11T21:14:56 < jpa-> the mechaduino approach of gluing a magnet to the motor shaft and putting magnetic sensor on the pcb in the back is kind of neat
2019-03-11T21:17:25 < Steffanx> isnt magnetic near the coils a bit noisy?
2019-03-11T21:18:07 < jpa-> perhaps, but at such a small distance (some millimeters) the neodymium magnet would overpower any noise by a large factor
2019-03-11T21:19:49 < srk> there's AGC on these
2019-03-11T21:20:13 < srk> can deal with external mag fields somehow as well

2019-03-11T21:22:25 < jpa-> hm, the basic FOC calculation for each sample is sin() + ~13 complex multiplications, i.e. ~50 float mul+adds, i.e. ~150 cycles
2019-03-11T21:23:28 < jpa-> 16 bit fixed point would also be plenty for it which would take only 2 cycles per complex multiply on cortex-m4; but then you have to be a bit ashamed of the code

2019-03-11T22:13:31 < jpa-> yeah, and what happens if you write some DMA control register at the same time as you write its enable bit?
2019-03-11T22:14:30 < jpa-> because they are on the same peripheral, they couldn't complete at once but one after another and would be serialized at the bus arbiter; but do they necessarily complete in the same order as in code?
2019-03-11T22:14:37 < jpa-> i haven't found the answer so far
2019-03-11T22:15:11 < c10ud> woah, sounds worrying
2019-03-11T22:15:51 < jpa-> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0646a/CHDHHFCC.html   suggests that order is guaranteed for the peripheral register areas, but not for general data memory

2019-03-11T22:18:42 < c10ud> well if that wasn't the case for peripherals I guess you would have to use lots of barriers
2019-03-11T22:19:12 < c10ud> which would spruce up the code a bit
2019-03-11T22:19:31 < jpa-> yeah

2019-03-12T17:33:15 < Adluc> do you guys tent vias?
2019-03-12T17:34:15 < PaulFertser> He wasn't banned even, the ban line was incorrect, not matching.
2019-03-12T17:35:06 < PaulFertser> As Cracki is not using identd so there's a ~ before his nick. I guess.
2019-03-12T17:35:26 < PaulFertser> Also, he's still on the channel, something a banned nick can't do afaik.
2019-03-12T17:36:47 < aandrew> Adluc: I tent all vias as a general rule, then un-tent ones that I might want to use as test points, but that's rare. I usually place intentional test point pads for that purpose, as my vias are small (0.2mm) 
2019-03-12T17:37:19 < aandrew> Haohmaru: um, a ban is not allowed to enter the chan. unless kicked/part, they can stay
2019-03-12T17:37:29 < aandrew> Haohmaru: it's voice that disallows them from talking when the chan is +m
2019-03-12T17:37:56 < aandrew> that's what I meant :-)
2019-03-12T17:38:12 < aandrew> if chan is +m, only +v/+o can speak
2019-03-12T17:38:24 < aandrew> however +b can exist and participate in the chan, just can't join
2019-03-12T17:40:10 < aandrew> not sure how a +b would have kept him quiet unless he was also kicked
2019-03-12T17:40:23 < aandrew> perhaps just as a warning?

2019-03-12T21:18:12 < PaulFertser> Ok, mawk, you're right, something made me sure ~ prepended to the nick is taken into account when matching bans, apparently not, thank you for correcting me.
2019-03-12T21:19:11 < mawk> yeah ~ is the ugly prefix irc servers that still think it's 1990 prepend to users that have no identd answering on their ips

2019-03-12T21:20:03 < mawk> but it's on the username yeah
2019-03-12T21:22:18 < PaulFertser> ~ makes sense, it helps to tell if users are using their login name (or being root on the host) or not.
2019-03-12T21:23:03 < mawk> yeah with a reasonable number of internet users that each have their own ips
2019-03-12T21:23:21 < mawk> and no ugly NAT or firewall or CGNAT or whatever blocking along the way
2019-03-12T21:23:52 < PaulFertser> Those behind NAT are not internet hosts so probably can't be really called internet users ;)
2019-03-12T21:24:11 < mawk> lol
2019-03-12T21:24:43 < mawk> I don't know why the internet authorities don't get back from microsoft/apple/whatever the thousand IPs they had at the time they thought it was unlimited
2019-03-12T21:24:46 < mawk> politics probably
2019-03-12T21:24:54 < mawk> same thing why they didn't take back ymca.int from the YMCA
2019-03-12T21:25:13 < BrainDamage> what really puzzles is that in this day and age ports < 1024 are still root reserved
2019-03-12T21:25:28 < PaulFertser> It wouldn't help much, IPv4 is exhausted anyway.
2019-03-12T21:25:36 < mawk> it would allow for even more cgnat !
2019-03-12T21:25:42 < mawk> so it's indeed a bad for a good, BrainDamage 
2019-03-12T21:25:43 < BrainDamage> it's not like we're in the 70s where the port number meant a trusted admit set it up
2019-03-12T21:26:55 < mawk> but you can still tweak it with /proc/sys/net/ipv4/ip_unprivileged_port_start
2019-03-12T21:27:36 < mawk> start the no-privileged-port revolution
2019-03-12T21:27:58 < BrainDamage> yes, but that requires root itfp
2019-03-12T21:28:10 < mawk> yeah
2019-03-12T21:28:26 < BrainDamage> it solves nothing until it becomes the new standard
2019-03-12T21:29:24 < mawk> if for whatever reason a local process, so with an unlimited network pipe, can crash the http server for instance, in the interval it can spawn a new one on port 80
2019-03-12T21:29:28 < mawk> that's the first thing I can think of
2019-03-12T21:29:33 < mawk> but I'm sure that would allow many other attacks
2019-03-12T21:34:33 < BrainDamage> there's plenty of critical internet-facing services that have ports >1024 nowdays
2019-03-12T21:34:40 < mawk> right
2019-03-12T21:35:01 < BrainDamage> relying on no-replace sounds a bit silly
2019-03-12T21:35:02 < mawk> but my attack doesn't work, linux already thought of it
2019-03-12T21:35:03 < mawk> too bad
2019-03-12T21:36:19 < mawk> well not really thought of it but I'm sure every critical server uses SO_REUSEPORT, and when you have that you need to have the same pid to bind a new socket over an existing one/a TIME_WAIT one
2019-03-12T21:36:22 < mawk> which defeats the attack
2019-03-12T21:37:36 < mawk> the same uid

2019-03-13T01:50:05 < jadew> is bitcoin dead?
2019-03-13T01:50:33 < friendofafriend> Eventually, probably will have a dead cat bounce.
2019-03-13T01:52:17 < jadew> am I understanding this correctly or is the difficulty adjustable?
2019-03-13T01:52:41 < Cracki> that's right, it's supposed to grow
2019-03-13T01:52:58 < jadew> I'm watching a video with a guy that says it gets adjusted
2019-03-13T01:53:03 < jadew> and that it got lowered recently
2019-03-13T01:53:04 < Cracki> I think they use moore's law and adjust sometimes
2019-03-13T01:53:11 < Cracki> lowered? hmm
2019-03-13T01:53:30 < jadew> yeah... so all that bullshit that it keeps increasing was just bullshit
2019-03-13T01:53:46 < Cracki> they had to keep it increasing :P
2019-03-13T01:54:08 < jadew> apparently they lowered it several times since october
2019-03-13T01:54:26 < Cracki> so... buy rigs?
2019-03-13T01:54:35 < mawk> difficulty adjusts automatically Cracki 
2019-03-13T01:54:45 < mawk> to get a constant mining rate
2019-03-13T01:55:01 < jadew> sounds stupid
2019-03-13T01:55:02 < mawk> but I don't think it's that tightly coupled to price
2019-03-13T01:55:05 < mawk> why ?
2019-03-13T01:55:31 < jadew> because when it was advertised to me, the big thing was that the complexity increased by itself
2019-03-13T01:55:45 < jadew> and it should have increased to a point where it just can't be mined anymore
2019-03-13T01:55:53 < jadew> and that's what gave bitcoin its value
2019-03-13T01:55:55 < Cracki> no, just exponentially
2019-03-13T01:56:17 < Cracki> difficulty != total number of possible coins
2019-03-13T01:56:17 < mawk> yeah the difficulty increases empirically, but it's not bound to increase
2019-03-13T01:56:21 < jadew> the fact that there's this impending unavailability of new bitcoin
2019-03-13T01:56:25 < mawk> and it has local fluctuations where it decreases anyway
2019-03-13T01:56:34 < jadew> but if they can change the mining difficulty, then it defeats the purpose
2019-03-13T01:56:41 < mawk> nobody can change it, jadew 
2019-03-13T01:56:42 < Cracki> nah, mining just gets you progressively fewer coin
2019-03-13T01:56:49 < mawk> it's in the source code, hardcoded
2019-03-13T01:56:53 < mawk> it's dynamic
2019-03-13T01:57:06 < mawk> difficulty adjusts according to a formula so that it takes X minutes to validate a block
2019-03-13T01:57:18 < Cracki> the number of coins is still limited, but the difficulty changes
2019-03-13T01:57:21 < mawk> if there are less miners, difficulty will decrease, vice-versa
2019-03-13T01:57:39 < Cracki> limited but never reached*
2019-03-13T01:57:43 < jadew> here's a question tho
2019-03-13T01:57:52 -!- rajkosto [~Rajko@cable-178-149-127-67.dynamic.sbb.rs] has joined ##stm32
2019-03-13T01:58:00 < jadew> when there are no more bitcoins left, who's going to validate those blocks and why?
2019-03-13T01:58:03 < mawk> it will be reached Cracki , it's not exponentially decreasing
2019-03-13T01:58:09 < Cracki> oh
2019-03-13T01:58:09 < mawk> constant mining rate will make constant difficulty
2019-03-13T01:58:13 < mawk> it's just that the reward gets lower and lower
2019-03-13T01:58:23 < mawk> and eventually no more coins can be mined, miners just get paid with tx fee
2019-03-13T01:58:40 < mawk> here the financial incentive will drop massively, difficulty too, and probably normal people can get back to mining
2019-03-13T01:58:43 < jadew> ah ha, so there's a fee there
2019-03-13T01:58:44 < Cracki> ah, right, mining incentives are (1) you mine coin (2) you get fees from transactions
2019-03-13T01:58:48 < mawk> yes
2019-03-13T01:58:54 < mawk> and when all coin has been mined, only (2)
2019-03-13T01:58:54 < Cracki> so if all coin has been mined, there's still fees to keep them going
2019-03-13T01:59:11 < Cracki> ic ic
2019-03-13T01:59:47 < jadew> this guy says a lot of big miners are selling their shit, because the cost of electricity per btc, is higher than what a bitcoin is worth
2019-03-13T02:00:17 < englishman> they moved to places with cheaper electricity, who then made special buttcoin mining rates because that shit is dumb as fuck

2019-03-13T02:03:55 < jadew> no reason to fuel a pseudo coin when they're sitting on mountains of gold
2019-03-13T02:04:09 < BrainDamage> well, more like, they cannot tax that shit
2019-03-13T02:04:28 < BrainDamage> if they could, they'd be much more eager

2019-03-13T12:55:47 < Sadale> I mean, why? Obviously it's not a wise choice to do that as of the info we've got today.
2019-03-13T12:55:54 < Laurenceb_123> we need a Canada style deal
2019-03-13T12:56:18 < Sadale> just a single referendum and we've got brexit :/

2019-03-13T12:58:02 < Sadale> Well, I don't quite buy the idea of democracy. Public opinion can be manipulated easily.
2019-03-13T12:59:42 < Sadale> And if there were a second referendum I bet that the brexit thing would not be a thing anymore. And a second one isn't happening. :/
2019-03-13T13:00:27 < Sadale> I think democracy is about how convincing a agenda sound, not what good it'd actually brings to the people.
2019-03-13T13:00:40 < Sadale> lol possibly

2019-03-13T13:11:29 < Sadale> took me 10 hours >_<
2019-03-13T13:12:13 < Sadale> In a nutshell it's a calculator for an obscure numeral.
2019-03-13T13:12:26 < Sadale> We've got base-10 numeral, roman numeral, and we've got toki pona numeral.
2019-03-13T13:13:09 < Sadale> Here's the site of the calculator, and you won't be able to understand that because English version isn't available :P https://ilonanpa.sadale.net/

2019-03-13T14:43:09 < dongs> yes obviously
2019-03-13T14:43:17 < dongs> its not something that would be in opensores shitlibs
2019-03-13T14:45:57 < kakimir> amateurish mistake

2019-03-13T14:48:14 < dongs> i'm ok with top/bottom but i wouldnt merge pins like that
2019-03-13T14:51:20 < jpa-> yeah, for some reason this symbol is drawn to follow the pins on the package
2019-03-13T14:51:25 < jpa-> and i was too lazy to make my own
2019-03-13T14:53:36 < dongs> wiat what
2019-03-13T14:53:43 < dongs> you used shit drawn by some random retard?
2019-03-13T14:53:45 < dongs> without checking it?
2019-03-13T14:56:03 < jpa-> sure i checked it, i even used it on another board and it worked
2019-03-13T14:56:11 < jpa-> then i just went full retard myself
2019-03-13T14:57:24 < dongs> im surprised a .5mm pitch dialog part is even in opensores libraries
2019-03-13T14:57:37 < dongs> like what kinda typical kikecad user is even got the equipment to soldedr it

2019-03-13T15:30:35 < kakimir> guise how did I get signedness warning of my uart_putchar parameter go away
2019-03-13T15:30:40 < kakimir> without changing warnings
2019-03-13T15:30:50 < jpa-> https://jpa.kapsi.fi/stuff/pix/via_drill.jpg   there, i fixed it
2019-03-13T15:30:56 < kakimir> I think it's const char *string
2019-03-13T15:30:59 < kakimir> now
2019-03-13T15:31:05 < jpa-> drilled from backside and cut the trace
2019-03-13T15:31:16 < kakimir> wait no* const uint8_t *string
2019-03-13T15:32:01 < kakimir> I have selected unsigned strings in build options
2019-03-13T15:32:06 < kakimir> or unsigned char
2019-03-13T15:32:42 < kakimir> everything works but 500warnings is a bit too much in order to find important ones efficiently
2019-03-13T15:35:11 < jadew> you should have none
2019-03-13T15:35:22 < jadew> so start with the first one
2019-03-13T15:38:29 < kakimir> it's all from call uart_putstring
2019-03-13T15:38:36 < kakimir> every instance of it
2019-03-13T15:39:00 < kakimir> I remember there was trick to format parameter so that it doesn't mind
2019-03-13T15:39:26 < kakimir> tried void *string but it was like nah
2019-03-13T15:39:58 < jadew> that would take any pointer
2019-03-13T15:41:26 < kakimir> it didn't like it
2019-03-13T15:41:31 < kakimir> it resulted in error
2019-03-13T15:42:06 < jadew> probably because you didn't use it properly in the function
2019-03-13T15:42:07 < kakimir> maybe it was const void *string
2019-03-13T15:42:28 < kakimir> should it matter if it's const or not?
2019-03-13T15:42:30 < jadew> either way, it's a bad idea to use void *, unless you know what you're doing
2019-03-13T15:42:37 < jadew> it does, yes
2019-03-13T15:42:48 < jadew> if the function doesn't want to change the object, use const
2019-03-13T15:42:56 < jadew> that way, you can pass both const and non const stuff
2019-03-13T15:43:10 < jadew> but if it's not const, then you can only pass non-const stuff
2019-03-13T15:43:23 < kakimir> oh wait the last time I had problem it was with that const stuff
2019-03-13T15:43:58 < kakimir> took a ride on tesla model 3 today
2019-03-13T15:44:01 < kakimir> nice
2019-03-13T15:44:50 < jadew> I've never been in an electric car
2019-03-13T15:45:36 < kakimir> I have driven P100D
2019-03-13T15:47:33 < Laurenceb> my car was giving engine warning lights yesterday :(
2019-03-13T15:48:04 < Laurenceb> obd2 tiem
2019-03-13T15:48:06 < kakimir> get a cable
2019-03-13T15:48:11 < Laurenceb> yeah
2019-03-13T15:48:30 < Laurenceb> it could be a faulty glow plug controller apparently
2019-03-13T15:48:40 < Laurenceb> also the power steering fluid is black :-S
2019-03-13T15:51:00 < kakimir> Laurenceb: just patch the car and drive it
2019-03-13T15:51:07 < kakimir> until it doesn't go anymore
2019-03-13T15:51:12 < Laurenceb> heh yeah
2019-03-13T15:51:24 < Laurenceb> it still drives fine, no issues today so far
2019-03-13T15:51:34 < kakimir> older it get's the nastier fixes you need to apply
2019-03-13T15:52:07 < Laurenceb> I did have a 1996 car, only issue was high tax and rusty suspension
2019-03-13T15:52:21 < Laurenceb> this is 2007 and loads of issues so far
2019-03-13T15:52:49 < jadew> it's 12 years old, what do you expect?
2019-03-13T15:52:52 < Laurenceb> it also has bad corrosion
2019-03-13T15:53:01 < kakimir> Laurenceb: what is your car now?
2019-03-13T15:53:04 < Laurenceb> ford
2019-03-13T15:53:05 < jadew> cars start falling apart after 5-6 years
2019-03-13T15:53:09 < jadew> 7 if you're lucky
2019-03-13T15:53:11 < Laurenceb> old one was opel
2019-03-13T15:53:22 < kakimir> vauxhal
2019-03-13T15:53:24 < Laurenceb> I should repair the opel lol
2019-03-13T15:53:25 < Laurenceb> yeah
2019-03-13T15:53:34 < kakimir> you still have it?
2019-03-13T15:53:38 < Laurenceb> yes
2019-03-13T15:53:53 < jadew> get a tesla
2019-03-13T15:53:55 < Laurenceb> even with repaired suspension it would cost ukp260/year in tax :(
2019-03-13T15:54:28 < kakimir> hmm my car is like 700eur in a year
2019-03-13T15:54:44 < Laurenceb> I will probably sell it, its worth more than my ford second hand cuz it has isuzu engine
2019-03-13T15:54:51 < jadew> speaking of cars, I'm on the lookout for a car too
2019-03-13T15:55:03 < jadew> not new tho, can't afford new now
2019-03-13T15:55:26 < Laurenceb> kakimir: wow expensive
2019-03-13T15:55:33 < Laurenceb> my ford is ukp20/year
2019-03-13T15:55:52 < jadew> that's cheap, it would be at least 50-100 here
2019-03-13T15:56:05 < Laurenceb> yeah uk vehicle tax is stupid
2019-03-13T15:56:06 < kakimir> Laurenceb: fokkin nothin
2019-03-13T15:56:36 < kakimir> :o
2019-03-13T15:56:38 < Laurenceb> same vauxhall but 6 months newer is half the tax, same engine but it was certified as euro3 compoliant
2019-03-13T15:57:36 < Laurenceb> people use the isuzu engines in 4wd and rally racing, I could sell it for >1k
2019-03-13T15:57:45 < Laurenceb> really nice torque 
2019-03-13T15:57:54 < Laurenceb> ford cdti is shit
2019-03-13T15:58:13 < jadew> ford in general is shit
2019-03-13T15:58:24 < jadew> we have a ford too
2019-03-13T15:58:24 < Laurenceb> I'm going to try a retune if the engine isnt fucked
2019-03-13T15:58:30 < Laurenceb> yeah as I'm discovering
2019-03-13T15:59:03 < Laurenceb> much worse corrosion on 2007 ford than 1996 vauxhall/opel
2019-03-13T15:59:10 < jadew> didn't have any major issues with it, it's an OK car, but it has lots of stupid issues
2019-03-13T15:59:28 < Laurenceb> in face 1996 vauxhall is almost factory condition apart from suspension arms
2019-03-13T15:59:33 < Laurenceb> *fact
2019-03-13T15:59:54 < Laurenceb> parked outside in uk weather all that time O_o
2019-03-13T16:00:07 < kakimir> I would pay the tax and drive it
2019-03-13T16:00:20 < jadew> I had a BMW before and that car was great
2019-03-13T16:00:21 < Laurenceb> ford has pitting corrosion everywhere, it needs a respray
2019-03-13T16:01:08 < Laurenceb> going to try fitting a "tunebox" to the ford to boost the shitty torque
2019-03-13T16:01:13 < mawk> you're the kind that does tuning I'm sure Laurenceb 
2019-03-13T16:01:14 < mawk> uh
2019-03-13T16:01:19 < mawk> exactly what I'm saying

2019-03-13T16:06:45 < kakimir> car manufs have their tricks
2019-03-13T16:06:49 < markus-k> afaik some actually do
2019-03-13T16:06:54 < kakimir> maybe it's new car smell patented by 3M
2019-03-13T16:07:03 < kakimir> sold only to car manufs

2019-03-13T16:44:07 < bitmask> Ive been using lastpass since 2014 because they seemed to have the most platforms supported but now that I'm trying to do extra stuff, nothing seems to work.

2019-03-13T16:45:23 < BrainDamage> keepass is quite similar to lastpass
2019-03-13T16:45:23 < bitmask> do those automatically pop up dialogs to save undetected passwords and offer to auto generate a password if one isnt found
2019-03-13T16:45:29 < BrainDamage> it's the sane version

2019-03-13T16:47:59 < kakimir> keepass has chrome plugin
2019-03-13T16:48:02 < bitmask> for low importance sites it doesnt matter to me
2019-03-13T16:48:11 < kakimir> at least keepassxc
2019-03-13T16:48:17 < bitmask> does it fill in android app passwords?
2019-03-13T16:48:29 < kakimir> *shrug*
2019-03-13T16:49:21 < zyp> I still memorize important passwords, but I've started using lastpass for anything else
2019-03-13T16:49:58 < bitmask> the only password I still know (that isnt a random character string) is my main email address 
2019-03-13T16:50:48 < zyp> Haohmaru, yeah, I used to reuse shit for unimportant shit, turns out it's still annoying when it leaks somewhere
2019-03-13T16:51:25 < bitmask> thats what I did until 2014, saw my password was leaked and started using a pw mgr
2019-03-13T16:51:27 < zyp> bitmask, why isn't your main email password a random character string?
2019-03-13T16:51:56 < bitmask> to make sure I can log into it no matter what
2019-03-13T16:52:10 < bitmask> if something like what just happened and I couldnt get into my password manager then I woulda been screwed
2019-03-13T16:52:10 < zyp> uh
2019-03-13T16:52:16 < zyp> I mean
2019-03-13T16:52:25 < bitmask> its pretty strong
2019-03-13T16:52:29 < zyp> you could memorize a random character string
2019-03-13T16:52:51 < bitmask> 16 characters, a typo, special characters, acronym, numbers
2019-03-13T16:52:59 < BrainDamage> most authentication mechanisms have email as fallback
2019-03-13T16:53:10 < BrainDamage> so if your email is vulnerable, so is everything else
2019-03-13T16:53:22 < zyp> correct horse battery staple
2019-03-13T16:53:37 < BrainDamage> no, that exact one
2019-03-13T16:53:39 < bitmask> the crypto method
2019-03-13T16:53:42 < zyp> but still
2019-03-13T16:54:07 < zyp> memorizing shit like hbqyh4sc isn't that hard
2019-03-13T16:54:26 < zyp> I didn't even try
2019-03-13T16:55:10 < zyp> -hbqyh4sc was the windows-generated suffix of the network name on one of my friends' computer when I was a kid
2019-03-13T16:55:24 < zyp> I still remember that shit 15 years later
2019-03-13T16:55:38 < mawk> I do that too
2019-03-13T16:55:48 < mawk> I went on random.org to generate a 20 characters random string
2019-03-13T16:55:53 < mawk> and used it as a password
2019-03-13T16:56:24 < zyp> yeah
2019-03-13T16:56:33 < bitmask> yea I remember my first house phone number from when I was a little kid

2019-03-13T17:03:22 < aandrew> Adluc: my vias are typically 0.2mm/0.4mm, but those are intentionally small. Dongs is right with 0.3/0.5 being more typical for a small via. 
2019-03-13T17:04:37 < aandrew> those are not really great for test points, at least not according to me, because I'd like to be able to slip a 30AWG wire into one if it's a test point. 0.3mm should do it but with plating I find it gets a little small
2019-03-13T17:07:34 < Laurenceb> vias that small must have been socially constructed

2019-03-13T17:22:11 < jadew> I'm so pissed off about these boards :/
2019-03-13T17:22:19 < jadew> $60 and I can't fucking use them
2019-03-13T17:23:47 < jadew> what's worst is that I've now compared with older boards and they got progressively worse
2019-03-13T17:23:52 < jadew> they were amazing at first
2019-03-13T17:24:11 < jadew> then they got a bit crappier, and a bit more
2019-03-13T17:24:18 < jadew> and now I got this awful shit
2019-03-13T17:24:29 < jadew> and all the time the price got higher
2019-03-13T17:25:13 < jadew> what's pissing me off is that I wasted time waiting for them
2019-03-13T17:25:33 < jadew> and that now I have to find a better PCB house
2019-03-13T17:25:52 < jadew> my goal is $2-3/board, before shipping or anything else
2019-03-13T17:26:11 < jadew> that should mean pretty good quality, right?
2019-03-13T17:26:32 < jadew> considering the current rate is ~50c/board (100x100 mm)
2019-03-13T17:27:51 < jadew> problem is the good PCB houses seem to want a lot more per board than that
2019-03-13T17:28:47 < jadew> micron20 for example is charging me 7 eur/board
2019-03-13T17:28:53 < jadew> that's 8 usd/board
2019-03-13T17:29:03 < jadew> before shipping

2019-03-13T18:27:58 < aandrew> leave won by the slimmest of margins, and it's clear that nobody actually wants to leave, but May is insistent that britain will leave
2019-03-13T18:28:01 < aandrew> why?
2019-03-13T18:29:18 < englishman> doesn't matter if the referendum passed by 1 vote, it passed
2019-03-13T18:29:34 < aandrew> yes I understand
2019-03-13T18:29:47 < englishman> anything other than brexit would be against the will of the people as voted upon
2019-03-13T18:30:51 < aandrew> but nobody seems to actually WANT to leave -- all proposed deals are shot down, everyone who was bullish on leaving has quit/stepped down, it's painfully obvious it's not the will of the people

2019-03-13T21:38:10 < PaulFertser> markus-k: the shitty part about nrf51/52 is that you can't debug it as usually due to softdevice running so you have to count on jlink rtt debug info instead. Other than that, well, it's a Cortex-M0 device, it works, softdevice seems to be ok, the SDK is kinda bloated but so what.
2019-03-13T21:39:52 < PaulFertser> Steffanx: it's not really fake news, that's the point. It's outright nonsense, as if you asked a 5 y.o. what he or she loves about science and decorate a whole train based on that with implications that's what science really is.

2019-03-13T22:56:29 < BrainDamage> getting 1MHz analol bandwith is not hard
2019-03-13T22:56:36 < BrainDamage> even the most cheap shit opamp can do it
2019-03-13T22:56:38 < Cracki> some people worked on "scope" firmware for stm32 because the builtin adcs can give you 1 MS/s at least

2019-03-13T22:59:30 < BrainDamage> bitmask: do you have a logic analyser?
2019-03-13T22:59:51 < BrainDamage> for that price you can get a tolerable logic analyser, and unlike that device, it won't be a toy
2019-03-13T23:00:05 < bitmask> a cheap one yea.  I guess the reason I am even considering one is to measure psu ripple, is that possible with something like this?
2019-03-13T23:00:21 < BrainDamage> depends, for linear psu yes
2019-03-13T23:00:30 < bitmask> yea linear
2019-03-13T23:00:37 < BrainDamage> for a switching, depending on the freq you'll only see 1-2 harmonics

2019-03-13T23:19:11 < Rajko> jyetech shit is cheap stm32 toy oscopes
2019-03-13T23:19:15 < bitmask> already said I wasnt
2019-03-13T23:19:38 < Rajko> for same money you can get a 48MHz FX2 based one thats completely a slave to computer
2019-03-13T23:20:14 < Rajko> or for a bit more you can get an isolated one with fpga, still uses a computer to view results but capture isnt fully passthrough like the fx2 one
2019-03-13T23:20:56 < Cracki> I doubt the 48 MHz number out of an fx2. for LA-use they can dump 24 MByte/s so you could have 8-bit 24 MS/s
2019-03-13T23:21:32 < Rajko> its still way better than these
2019-03-13T23:21:36 < Rajko> the display on these is TN btw so you cant see shit
2019-03-13T23:21:37 < Cracki> certainly
2019-03-13T23:21:38 < Rajko> it hurts eyes
2019-03-13T23:21:56 < Cracki> if you want to spend 50 bucks, I think there are mixed signal LA/"scope" thingies... dslogic clones might be that cheap
2019-03-13T23:22:03 < Cracki> worth a look anyway

2019-03-13T23:24:15 < Rajko> its just a FX2 connected to DAC
2019-03-13T23:24:27 < Rajko> the computer processes all data, does auto ranging and triggering etc
2019-03-13T23:24:32 < Rajko> i mean ADC*
2019-03-13T23:25:10 < Rajko> it does 2x 24MSPS or 1x 48MSPS
2019-03-13T23:25:16 < Cracki> interesting! how do they get 48 MS/s...
2019-03-13T23:25:23 < Cracki> compression maybe
2019-03-13T23:25:26 < Rajko> the FX2 can run its clock at 48MHz
2019-03-13T23:25:28 < Rajko> samples 8 bits
2019-03-13T23:25:35 < Rajko> or it samples 16 bits at 24MHz
2019-03-13T23:25:45 < Cracki> still, 48 MB/s is not doable for USB2

2019-03-13T23:32:15 < BrainDamage> those oscopes don't run in realtime
2019-03-13T23:32:31 < rajkosto> the owon doesnt, no
2019-03-13T23:32:51 < BrainDamage> they buffer, send a chunk, then have a gap

2019-03-13T23:49:29 < jadew> elecrow, they used to have decent quality, but it has slowly declined and now they're just bad all around
2019-03-13T23:49:48 < jadew> the soldermaks is spotted and poorly applied too
2019-03-13T23:50:03 < jadew> a year ago they used to be perfect
2019-03-13T23:50:45 < jadew> I've been using them for about 3 years I think and they were always ok, up until half a year or so ago

2019-03-13T23:51:22 < jadew> now it looks like someone made it in their bathroom and applied the solder mask with an iron
2019-03-13T23:52:45 < jadew> I think they've changed processes or maybe they hired another board house to deal with the volume?
2019-03-13T23:53:08 < jadew> the silkscreen seems to be completely different than before
2019-03-13T23:53:26 < jadew> before it was made out of small dots and it looked okish, not the greatest, but it was decent

2019-03-14T00:33:04 < jadew> like... from a tool
2019-03-14T00:33:06 < Cracki> maybe start a table or document otherwise the various pcb houses you tried, and how you judge their results

2019-03-14T00:35:35 < jadew> what bothers me the most is that they had the boards in their hands and they said "ok, these are good enough, send them"

2019-03-14T00:36:03 < Cracki> prolly swapped house from china to india :>
2019-03-14T00:36:07 < jadew> when they should have said "ok, trash them, let's make new ones"
2019-03-14T00:36:36 < jadew> yeah, it's possible they hired another house to deal with the volume
2019-03-14T00:37:02 < jadew> but it's something that must have happened a long time ago, because I've seen the quality decline from order to order
2019-03-14T00:37:32 < jadew> I've seen this kind of silkscreen before from them, but it wasn't this bad

2019-03-14T01:54:27 < ds2> ah
2019-03-14T01:55:27 < jadew> I guess what I have to find now is a board house that does nice silkscreen and doesn't put random numbers on the boards
2019-03-14T01:55:47 < ds2> what random numbers? the EIA/UL/etc stamps?
2019-03-14T01:56:17 < jadew> no, random shit the cheap chinese manufacturers put on the board in order to track it
2019-03-14T01:56:32 < ds2> oh those... and they put on the silk?
2019-03-14T01:56:39 < jadew> yeah
2019-03-14T01:56:43 < jadew> and in a random place
2019-03-14T01:56:47 < jadew> you can't choose
2019-03-14T01:57:10 < rajkosto> its not random they just find a big enough space
2019-03-14T01:57:11 < jadew> they usually try to hide it under a footprint, but you don't always get lucky
2019-03-14T01:57:15 < rajkosto> usually behind some TQFP
2019-03-14T01:57:30 < ds2> how are the prices for pcbpool?
2019-03-14T01:57:38 < ds2> based in germany, IIRC
2019-03-14T01:57:49 < jadew> high
2019-03-14T01:57:51 < jadew> very high
2019-03-14T01:58:06 < ds2> better then the 175 EUR I'd think
2019-03-14T01:58:08 < jadew> similar to eurocircuits
2019-03-14T01:58:13 < jadew> not by much
2019-03-14T01:58:27 < ds2> they don't seem expensive in the US
2019-03-14T01:59:50 < jadew> all the EU ones seem to be in that ballpark
2019-03-14T02:00:06 < jadew> not sure why
2019-03-14T02:00:42 < jadew> I doubt they're all top-level board manufacturers
2019-03-14T02:00:50 < ds2> as far as I know, pcbpool ships from europe
2019-03-14T02:01:07 < ds2> wonder if its the vat and vats of stuff
2019-03-14T02:01:56 < jadew> just got another quote to make sure, they're asking for 164 EUR
2019-03-14T02:27:53 < Adluc> jadew: https://www.gatema.cz/plosne-spoje
2019-03-14T02:28:05 < Adluc> i have good experience with these, near brno, czech republic
2019-03-14T02:28:36 < Adluc> https://www.gatema.com/printed-circuits
2019-03-14T02:29:22 < Adluc> for some reason only czech version offers pool service -_-

2019-03-14T02:32:47 < jadew> unfortunately they only do 1.6mm PCBs
2019-03-14T02:33:36 < Adluc> 1.5mm in pool
2019-03-14T02:33:54 < jadew> but yeah, they seem to be much cheaper than the rest
2019-03-14T02:34:35 < Cracki> just asking... jlcpcb.com or dirtypcbs.com or pcbshopper.com are unsuitable?
2019-03-14T02:35:14 < Cracki> not sure if allpcb is jlcpcb, but it's in my bookmarks
2019-03-14T02:35:17 < jadew> I don't like that they add the order number to the silkscreen
2019-03-14T02:35:31 < jadew> from the reviews it seems jlpcb has the best silkscreen
2019-03-14T02:35:42 < Cracki> also got pcbway, never tried it
2019-03-14T02:36:34 < jadew> pcbway has shitty silkscreen it seems
2019-03-14T02:36:44 < jadew> at least they had in the reviews I've seen
2019-03-14T02:36:49 < Cracki> if you don't like eurocircuits, I think wuerth isn't just a reseller of them https://www.wedirekt.de/en/
2019-03-14T02:37:04 < Cracki> (wuerth is generally a respectable name)
2019-03-14T02:37:13 < Cracki> good to know
2019-03-14T02:37:15 < jadew> for all I know, they're all using the same sweat shops and it doesn't really matter who you're buying from
2019-03-14T02:37:52 < jadew> Cracki, funny you mention them, they called me a couple of days ago
2019-03-14T02:38:01 < Cracki> maybe they sort and dispatch by complexity to the rattier or the more upstanding shops
2019-03-14T02:38:07 < Cracki> they did? that's good :P
2019-03-14T02:38:13 < jadew> but I checked them out too and they are among the priciest
2019-03-14T02:38:37 < sync> maybe try quickturn pcb in korea?
2019-03-14T02:38:46 < jadew> yeah, they saw I bought some RF gasket and thought they'd give me a call
2019-03-14T02:39:09 < jadew> sync, I'll check it out, thanks
2019-03-14T02:41:39 < jadew> sync, they don't have Romania in the shipping list :P
2019-03-14T02:42:03 < jadew> their quote is 100 USD before shipping & taxes, which might make them more expensive than the european houses
2019-03-14T02:43:39 < jadew> wait
2019-03-14T02:43:54 < jadew> $110
2019-03-14T02:45:45 < Adluc> jadew: from gatema, 4L, enig, 18/35/35/18um, HAL, 10 panels 265x403mm -> 125 eur setup fee, 10,92 eur per piece
2019-03-14T02:45:48 < Adluc> 234 eur total
2019-03-14T02:46:23 < Adluc> solder mask black ^_^
2019-03-14T02:46:27 < jadew> that's not bad
2019-03-14T02:46:40 < Adluc> not enig, HAL, typo
2019-03-14T02:46:51 < jadew> that's fine, I don't want ENIG anyway
2019-03-14T02:46:55 < jadew> it's lead free tho?
2019-03-14T02:46:58 < Adluc> yes
2019-03-14T02:47:36 < Adluc> they have only lead free/enig/OSP
2019-03-14T02:49:24 < Adluc> even beating china in some cases, plus you know they dont dump shit to river
2019-03-14T02:49:42 < Adluc> minus customs bullshits
2019-03-14T02:50:01 < jadew> yeah, that's a huge plus
2019-03-14T02:50:05 < jadew> shipping should be cheaper too
2019-03-14T02:50:14 < Adluc> 10 eur max
2019-03-14T02:50:37 < Adluc> from czech to slovakia i think or so it was
2019-03-14T02:54:37 < jadew> how did you get that quote?
2019-03-14T02:54:58 < jadew> it's asking me for email, company name, etc
2019-03-14T02:56:17 < Adluc> sad part follows: you have to ask for a price quotation and human will send you one back
2019-03-14T02:56:42 < jadew> I see
2019-03-14T02:56:47 < Adluc> so you have to register
2019-03-14T02:57:20 < jadew> trying to find pictures of their PCBs, but can't find many
2019-03-14T02:57:27 < jadew> only a couple of images from their own website
2019-03-14T02:57:41 < Adluc> i have some photos i think
2019-03-14T02:59:28 < jadew> got one where the silkscreen quality is visible?

2019-03-14T03:02:48 < Adluc> (actually totally incorrect PMOD footprint on the pcb you can see :D)

2019-03-14T03:17:23 < Cracki> tooling is the `b` in ax+b?
2019-03-14T03:18:00 < Cracki> someone's gonna look at the data and puzzle it into a sheet
2019-03-14T03:18:03 < sync> well, they have to import your shit in their intermediate format and possibly panelize it
2019-03-14T03:18:13 < sync> and that takes time
2019-03-14T03:18:31 < sync> after that they probably just tell the line how many and everything is figured out automagically

2019-03-14T09:37:56 < no0b> blue pill, not poll..
2019-03-14T09:42:40 < jpa-> how are you changing it?
2019-03-14T09:42:56 < jpa-> it seems you are getting the descriptor corrupted somehow
2019-03-14T09:44:25 < no0b> in the example it says: USBComposite.setVendorId(0x0030);
2019-03-14T09:44:59 < jpa-> hm, -71 is EPROTO which according to here is low level communication error or just timeout  https://github.com/torvalds/linux/blob/6f0d349d922ba44e4348a17a78ea51b7135965b1/Documentation/driver-api/usb/error-codes.rst

2019-03-14T11:03:40 < Steffanx> libmaple was hot when started with stm32. Is it still a thing?
2019-03-14T11:03:58 < rajkosto> usbcomposite requires it
2019-03-14T11:04:35 < Steffanx> Maple much
2019-03-14T11:04:49 < rajkosto> which is a shame otherwise i could use that lib
2019-03-14T11:09:34 < Sadale> Just use whatever library suits your use case the most :P

2019-03-14T18:35:20 < mawk> how did you brick it ?
2019-03-14T18:35:42 < zyp> tried to unlock CPU2 so I could run my own code on it
2019-03-14T18:36:32 < zyp> unlocking it would erase crypto blob that decrypts encrypted radio firmwares
2019-03-14T18:36:34 < mawk> so it couldn't be done ? or you just made a mistake
2019-03-14T18:36:39 < mawk> ah
2019-03-14T18:36:43 < mawk> why is it encrypted ? that sucks
2019-03-14T18:36:47 < mawk> it's IP ?

2019-03-14T18:38:12 < zyp> apparently I managed to erase the locked area of the flash, but it's still force locked so I can't rewrite it
2019-03-14T18:38:40 < mawk> isn't it said in the eeprom feature bytes or somethign ?
2019-03-14T18:38:50 < zyp> which means I still can't run my own code on CPU2, and now there's nothing else for it to run either
2019-03-14T18:38:59 < zyp> yes
2019-03-14T18:39:12 < zyp> there's an ESE bit in the option bytes that controls whether it's locked
2019-03-14T18:39:19 < zyp> and I've managed to write that to 0
2019-03-14T18:39:37 < mawk> right
2019-03-14T18:39:49 < mawk> and that should clear the flash and let you the hand
2019-03-14T18:39:52 < zyp> but the shit that loads the option bytes says «fuck you» and load it as 1 anyway
2019-03-14T18:39:56 < englishman> so you bricked cpu2?
2019-03-14T18:40:01 < zyp> englishman, yes
2019-03-14T18:40:04 < englishman> yikes
2019-03-14T18:40:35 < englishman> esp32 sure makes all that "pro" shit look bad
2019-03-14T18:41:03 < englishman> that's like avr-level fail
2019-03-14T18:41:10 < zyp> well, I don't blame anybody but myself
2019-03-14T18:42:40 < zyp> according to the release revision of the RM, it's not supposed to be possible to unlock CPU2
2019-03-14T18:43:01 < zyp> the prerelease I got a copy of however documents the method I tried :p
2019-03-14T18:43:11 < zyp> all that stuff got stripped out of the release
2019-03-14T18:43:44 < zyp> which is fair enough
2019-03-14T18:44:40 < zyp> overall, having a locked CPU2 that runs a radio blob is still less hassle than getting a radio blob that you have to share a cpu with
2019-03-14T18:45:23 < zyp> so stm32wb still seems like a good platform for what I want to do
2019-03-14T18:46:02 < zyp> which is why I stopped fucking around with CPU2 and started on bringing up the other peripherals instead
2019-03-14T18:46:18 < zyp> I don't get why USB doesn't work
2019-03-14T18:48:11 < zyp> ah, I think I've figured it out
2019-03-14T18:50:06 < zyp> apparently there's a bit in the PWR block that gates the VDDUSB supply
2019-03-14T18:50:09 < Laurenceb> > I don't get why USB doesn't work
2019-03-14T18:50:13 < Laurenceb> welcome ot the club

2019-03-14T20:27:36 < jadew> ?
2019-03-14T20:29:47 < Ultrasauce> yeah they're quarantined for 2 weeks or something before launch
2019-03-14T20:31:27 < jadew> they probably have the best medicine there tho
2019-03-14T20:31:53 < jadew> they can probably go through the flu without even knowing they have it
2019-03-14T20:33:09 < jadew> how long are these missions?

2019-03-14T20:48:57 < jadew> they must have powerful fans now
2019-03-14T20:49:06 < jadew> some sort of vacuum system?
2019-03-14T20:49:24 < jadew> if all fails, they can just crack the window
2019-03-14T20:49:25 < Cracki> hey mission control, could you check that "data dump" please
2019-03-14T20:49:42 < Cracki> I'm sure they have lots of filters up there and vacuum too
2019-03-14T20:50:05 < Cracki> that was apollo 8. for ISS they said they have to have circulation/ventilation or you suffocate

2019-03-14T21:24:24 < Cracki> sorry, all I can think of is solder to pcb, then mount that behind the panel
2019-03-14T21:25:19 < jpa-> you can also hotglue it to panel
2019-03-14T21:25:37 < Cracki> some googling shows me, also 3M, panelmount types, but more like scsi
2019-03-14T21:26:31 < Cracki> this looks like it can be screwed down but I don't see latches http://www.chipmall.com/product/assmann-wsw-components/awh-16g-e202-idc/2421614

2019-03-14T21:29:48 < jpa-> heh, those links show some totally different chips for me
2019-03-14T21:30:09 < jpa-> but google finds it with product number

2019-03-14T22:14:55 < Laurenceb> usb is broken
2019-03-14T22:15:13 < Laurenceb> heavy vehicle vibration can cause connectors to lose contact
2019-03-14T22:15:27 < Laurenceb> need usb over ethernet or something

2019-03-14T22:18:56 < Laurenceb> heh lunix doesnt like nasty breaking usb
2019-03-14T22:19:06 < Laurenceb> tho it is probably doing the best it can
2019-03-14T22:19:47 < Laurenceb> sometimes devices get dropped and dont re-enumerate

2019-03-14T22:39:42 < Laurenceb> dunno how that could actually work tho...
2019-03-14T22:40:10 < Laurenceb> there is probably a way to reset the state machine thing to force it to re enumerate failed stuff
2019-03-14T22:41:16 < Laurenceb> something like
2019-03-14T22:41:32 < Laurenceb> if(enumeration failed using regular state machine)

2019-03-14T23:50:22 < Laurenceb> at least the gui shows a sync error warning if that happens
2019-03-14T23:51:12 < Laurenceb> it can take up to 45s to recover from nasty usb events, but thats all due to lunix usb stuff
2019-03-14T23:52:39 < Laurenceb> sync codez is up to 5k lines :S

2019-03-15T16:54:38 < kakimir> I want shitty cables to stop exist
2019-03-15T16:54:49 < Cracki> usb c, or at least usb 3 plugs, those are kinda robust
2019-03-15T16:55:15 < kakimir> nobody stops making them shitty too
2019-03-15T16:55:23 < Cracki> ah right, chinesium cables with a single strand of coppery hair
2019-03-15T16:55:37 < kakimir> and bad contact tension
2019-03-15T16:55:45 < Cracki> can be fused if you give them an amp or two
2019-03-15T16:56:19 < kakimir> give an amp and there is no voltage left in another end
2019-03-15T16:56:23 < Cracki> the graphite pencil could carry more current than that chinesium usb cable I once had
2019-03-15T16:56:50 < aandrew> dongs: damn I did not know of this feature
2019-03-15T16:56:52 < aandrew> that is nice
2019-03-15T16:56:55 < kakimir> I should cut these in half and throw in a bin but it would mean I needed to get good ones before continuing

2019-03-15T16:59:05 < kakimir> is there a way for interrupt to exit a function currently executing immedietelly
2019-03-15T17:00:41 < dongs> aandrew: i had to move a bunch of shit from a single sheet into separate sheets and i got tired of copypasting nad losing refdes and i didnt wann go to settings to turn that option off.
2019-03-15T17:00:43 < kakimir> without conditions inside the function
2019-03-15T17:00:45 < dongs> so i looked around edit menu and found it
2019-03-15T17:00:47 < Cracki> uhhh sure, if you're comfortable dicking with the stack frame
2019-03-15T17:00:56 < kakimir> that is what I thought
2019-03-15T17:00:59 < Cracki> I'm not sure that's within th erule book of c/c++ tho
2019-03-15T17:01:01 < kakimir> better not do that
2019-03-15T17:01:07 < Cracki> you can...
2019-03-15T17:01:14 < kakimir> better not
2019-03-15T17:01:30 < kakimir> my code is the robbustness

2019-03-15T17:02:56 < dongs> i believe its a stepup
2019-03-15T17:03:40 < dongs> oh its MP1542
2019-03-15T17:03:41 < Cracki> plug it in and voltage probe?
2019-03-15T17:03:44 < BrainDamage> look at how the coil is wired and you'll know
2019-03-15T17:03:53 < aandrew> interesting
2019-03-15T17:03:54 < dongs> i was miserading that 1542D as 15420
2019-03-15T17:04:03 < aandrew> I made two digikey orders yesterday
2019-03-15T17:04:16 < aandrew> the first one hasn't arrived but the second (order made later) just arrived
2019-03-15T17:04:30 < aandrew> the one that arrived has a bunch of oscs which is the more imporatnt one
2019-03-15T17:05:09 < aandrew> huh, fedex tracking has "pending" on that one
2019-03-15T17:05:16 < aandrew> probably won't arrive until monday
2019-03-15T17:05:27 < dongs> hmm that is weird
2019-03-15T17:05:32 < dongs> that part has no current limit...
2019-03-15T17:05:59 < dongs> i mean, it has internal 2.6A but the shit its used on is supposed to drop dead after 500mA 
2019-03-15T17:06:03 < dongs> otherwise shit will start smoking
2019-03-15T17:08:56 < aandrew> if that song didn't have that fucking rushing noise every 10s it'd be okay
2019-03-15T17:10:40 < jpa-> dongs: that 2.6A is on the switch, remember to divide by the boost ratio
2019-03-15T17:10:53 < dongs> yeah?
2019-03-15T17:10:58 < dongs> i think its taking 12V to 15V or so
2019-03-15T17:11:08 < jpa-> ah, so not much higher
2019-03-15T17:11:36 < dongs> wait now what hte hell
2019-03-15T17:11:41 < dongs> its taking 5V to 17V
2019-03-15T17:11:48 < dongs> wtf this is completely out of spec
2019-03-15T17:12:24 < jpa-> so the most it could ever output is 0.76 A, and in practice much lower for continuous current
2019-03-15T17:12:32 < dongs> hmmmm
2019-03-15T17:12:39 < dongs> maybe that's what they're hoping for then?
2019-03-15T17:12:39 < dongs> hmmm
2019-03-15T17:13:39 < dongs> what the fuck
2019-03-15T17:13:46 < dongs> it turns into 15V after soemthing

2019-03-15T17:19:44 < dongs> the fuck is going on here
2019-03-15T17:20:02 < dongs> are they abusing these parts as some kinda current limiter?

2019-03-15T17:24:38 < dongs> PeterM would probly know if he wasnt sleeping
2019-03-15T17:29:02 < kakimir> but for sure general LDOs are not just voltage regulators but can be bent to do many type of stuff and it's ok
2019-03-15T17:31:11 < jpa-> dongs: how do you figure those are LM1117?
2019-03-15T17:33:21 < dongs> jpa, GH16C/GH16D
2019-03-15T17:33:26 < dongs> are diodesInc LM1117 markings

2019-03-15T17:33:49 < dongs> anyway, i checked those are just LDOs for unrelated bits of the circuit

2019-03-15T17:40:14  * Laurenceb brainmelt
2019-03-15T17:40:27 < dongs> nice code 
2019-03-15T17:41:04 < Laurenceb> there is some sort of rare bug if lots of devices fail at the same time
2019-03-15T17:41:18 < Laurenceb> they can end up misaligned by 2.048s once they reconnect
2019-03-15T17:41:22 < Laurenceb> funtimes
2019-03-15T17:42:12 < Laurenceb> tfw still better than alsa
2019-03-15T17:42:14 < dongs> can 1.5V fixed LDO be used to make 1.8V?
2019-03-15T17:42:18 < dongs> by adding some resistor to adj?
2019-03-15T17:42:53 < Laurenceb> alsa + audacity locks up in minutes under really bad road conditions
2019-03-15T17:45:17 < jpa-> dongs: adding a series resistor to GND/ADJ usually
2019-03-15T17:46:08 < dongs> it can only increase, right
2019-03-15T17:50:57 < dongs> well according to that pic they're just adding a R to GND/ADJ pin
2019-03-15T17:51:11 < dongs> hmm.
2019-03-15T17:51:32 < dongs> still dont understand how 17V becomes 15 if its not going through those parts.
2019-03-15T17:51:44 < dongs> but thats to figure out tomorrw, sleep time
2019-03-15T17:52:34 < jpa-> dongs: you can also decrease by putting resistor divider between ground, adj and vout
2019-03-15T17:55:27 < Laurenceb> arg this code is giving me brain cancer
2019-03-15T17:56:34 < jpa-> Laurenceb: uh oh.. i know you have a pretty high tolerance when it comes to crap links on internet, but never, never, open https://github.com/Laurenceb if you want to avoid headache!

2019-03-15T18:08:08 < Laurenceb> my code is built around the assumption it doesnt take >1.024s to reconnect
2019-03-15T18:08:47 < Laurenceb> but it can take 3s or so
2019-03-15T18:09:01 < kakimir> wow such failure in code
2019-03-15T18:09:08 < kakimir> but no negative effects
2019-03-15T18:09:18 < Laurenceb> heh it works ok 99% of the time
2019-03-15T18:09:21 < kakimir> because how reseived areas are in registers
2019-03-15T18:09:35 < kakimir> and how default values of fields are
2019-03-15T18:09:37 < Laurenceb> its built around 11 bit usb frame number logic, which overflows
2019-03-15T18:10:20 < Laurenceb> ironically my "nasty hack" usb audio sync code works perfectly, so it can probably all be fixed with copypastering
2019-03-15T18:11:25  * Laurenceb fails to remember usb spec...
2019-03-15T18:11:56 < Laurenceb> aiui a host will stop trying to enumerate a device that fails to enumerate after numerous attempts?
2019-03-15T18:12:55 < Laurenceb> in which case lunix is just following the spec when my devices sometimes disappear :-/

2019-03-15T19:06:19 < STWDG> I've been trying to play with the watchdog and it seems to do it's job by causing a reset, but I'm unable to handle any interrupt for it. I'm using the HAL library.
2019-03-15T19:06:25 < STWDG> ... v1.24
2019-03-15T19:07:09 < STWDG> I was at least hoping I could set a breakpoint on the WWDG_IRQHandler.
2019-03-15T19:07:30 < STWDG> I know the EXTI0_IRQHandler is working as expected for me.
2019-03-15T19:07:53 < Laurenceb> thats the windowed watchdog
2019-03-15T19:09:44 < STWDG> yup.
2019-03-15T19:10:06 < STWDG> I take it from your statement that my expectations are incorrect?
2019-03-15T19:10:07 < Laurenceb> was wondering if you confused watchdog with windowed watchdog
2019-03-15T19:10:09 < Laurenceb> nvm
2019-03-15T19:10:14 < STWDG> ah.

2019-03-15T21:29:11 < Steffanx> A mouse.
2019-03-15T21:29:31 < superbia1> I think I got one back at home
2019-03-15T21:29:43 < superbia1> gray with black stains, or some circular shittery on top
2019-03-15T21:29:51 < Steffanx> What kind of mouse are you referring to?
2019-03-15T21:29:57 < superbia1> has like 16 feet pads
2019-03-15T21:30:03 < superbia1> i think the g502 ?

2019-03-15T21:43:43 < superbia1> if you buy kit, you can save huge dollar... buy from japan and save even more dollar
2019-03-15T21:44:06 < Steffanx> What was it again?
2019-03-15T21:44:08 < superbia1> only downside is that you will have to assemble it yourself, which trust me is not a trivial task
2019-03-15T21:44:35 < superbia1> google helix keyboard (will get some random manga japanese website you can purchase it on)
2019-03-15T21:46:13 < Steffanx> Tried to find a picture or video of someone actually using it.. didnt find any :P
2019-03-15T21:46:54 < superbia1> go on youtube, look for Iris Keyboard Build
2019-03-15T21:52:06 < Steffanx> hm
2019-03-15T21:53:55 < superbia1> the only real problem is that it can happen that a row / collumn dies for like a few seconds, just enough so you can't figure out where is a weak joint
2019-03-15T21:54:32 < superbia1> happens to the best of us (happened to me)
2019-03-15T21:57:31 < Steffanx> Do you actually use it for your programmin job or just at home
2019-03-15T21:57:51 < superbia1> home
2019-03-15T21:58:03 < superbia1> it's kind of loud though

2019-03-15T23:17:59 < englishman> Steffanx: microsoft sculpt keyboard is awesome
2019-03-15T23:18:08 < englishman> with separate numpad
2019-03-15T23:18:14 < englishman> perfect pro irc EE setup
2019-03-15T23:18:44 < Steffanx> im not convinced.
2019-03-15T23:18:58 < englishman> you dont have to be convinced. its like $50
2019-03-15T23:19:28 < Steffanx> are you talking about hte one with the gap in the middle?
2019-03-15T23:19:34 < englishman> yes
2019-03-15T23:19:46 < englishman> like the old microsoft natural keyboards from 30 years ago
2019-03-15T23:19:49 < Steffanx> make that 90 euro times dollar currency.
2019-03-15T23:20:04 < Steffanx> = 102 dollar bucks
2019-03-15T23:20:14 < englishman> still 1/5 what you will spend on some gay opensores keyboard with tarduino. and actually works
2019-03-15T23:20:42 < englishman> and like 5 fucking cables coming out of it
2019-03-15T23:20:42 < englishman> wtf
2019-03-15T23:20:46 < Steffanx> i wouldnt buy such thing
2019-03-15T23:20:52 < Steffanx> or make
2019-03-15T23:21:02 < englishman> clearly a pro ^
2019-03-15T23:21:40 < Steffanx> Anyway its not $50 :P
2019-03-15T23:22:10 < Steffanx> it seems it was 4 years ago
2019-03-15T23:22:34 < englishman> idk maybe amadongs is screwy
2019-03-15T23:22:37 < englishman> where you are
2019-03-15T23:23:19 < Steffanx> https://tweakers.net/pricewatch/351114/microsoft-sculpt-ergonomic-keyboard-(qwerty-nl).html there 
2019-03-15T23:23:38 < Steffanx> and yes, we dont amazon
2019-03-15T23:23:45 < englishman> thats not amazon
2019-03-15T23:23:51 < Steffanx> i know, we dont amazon.
2019-03-15T23:23:55 < englishman> no wonder you pay more
2019-03-15T23:24:11 < Steffanx> i could amazon.de but usually amazon shows up in that list as well
2019-03-15T23:24:17 < englishman> at staples it was like $150
2019-03-15T23:24:24 < Steffanx> but zhe germans dont qwerty
2019-03-15T23:24:32 < englishman> its probably banned in germany
2019-03-15T23:24:42 < englishman> cuz you could potentially type a swastika with it
2019-03-15T23:24:50 < Steffanx> Anyway, reviews are so-so.
2019-03-15T23:25:08 < englishman> the thing about keyboard reviews
2019-03-15T23:25:15 < englishman> is that they are done by keyboard reviewers
2019-03-15T23:25:26 < Steffanx> nah, not on this website.
2019-03-15T23:25:41 < Steffanx> the dutch nerd scene.
2019-03-15T23:25:46 < englishman> even worse
2019-03-15T23:25:58 < Steffanx> Yes, those are not irc ee pros
2019-03-15T23:26:20 < Steffanx> Ill stick to my apple keyboard :)
2019-03-15T23:26:28 < englishman> the little numpad has totally replaced my casio calculator
2019-03-15T23:33:41 < jadew> had an ergonomic keyboard once
2019-03-15T23:33:53 < jadew> didn't like it
2019-03-15T23:34:20 < jadew> regular keyboards don't bother me
2019-03-15T23:37:28 < jadew>  the only keyboards that bother me are sticky ones
2019-03-15T23:42:27 < rajkosto> tarduino keyboards are hillarious

2019-03-16T00:06:57 < Steffanx> Not sure
2019-03-16T00:07:06 < rajkosto> i tried it before it was acquired and when it cost money and it constantly bothered you to buy it if you were using free ver lol

2019-03-16T03:27:47 < karlp> we'll see what happens there now.
2019-03-16T03:27:47 < englishman> guns are always doing that.
2019-03-16T03:28:17 < englishman> they have already promised to ban everything and think about things later

2019-03-16T03:38:50 < karlp> the artik020 used on the balenaFin is a white-label rebrand of the Silicon Labs bgm111, which is not being discontinued. Future boards will come with a Silicon Labs branded module but they’re the entirely the same thing underneath
2019-03-16T03:38:51 < englishman> good thing i still have a few hundo Edisons
2019-03-16T03:39:11 < karlp> balen being resin.io,  no idea why they're making hardware honestly.

2019-03-16T09:22:11 < PaulFertser> Pro wifi advice: for penetrating the walls you need three antennas as the first will be blocked by the first wall, the second by the second, and the third will reach the AP! https://img.staticbg.com/images/oaupload/banggood/images/7E/01/41670c9f-b3ce-4791-8544-6df8b7149844.jpg
2019-03-16T09:24:05 < jpa-> only one-directional comms though, as the AP has only two antennas
2019-03-16T09:27:50 < PaulFertser> Probably this cam can be hacked to use https://github.com/svpcom/wifibroadcast for uni-directional video streaming

2019-03-16T11:28:33 < antto> jpa-, i saw you're using some semi-cheap usb scope.. and it looks pretty nice.. what do you think about this more ghetto model? https://www.ebay.co.uk/itm/202403566060/
2019-03-16T11:29:13 < antto> i probably won't use its built-in LEDs coz it's gonna suck, so ignoring that..
2019-03-16T11:33:39 < jpa-> the one i use actually has its own display
2019-03-16T11:33:52 < jpa-> over USB it has too much lag for soldering etc.
2019-03-16T11:34:05 < jpa-> so i'd recommend one that has either own display or HDMI output
2019-03-16T11:34:42 < jpa-> if you only need it for checking results though, then that's probably fine

2019-03-16T11:55:30 < tjq> hahahha
2019-03-16T11:55:54 < antto> well, at the j0b i got one of these: https://cdn.chv.me/images/6bUp4sPz.jpg
2019-03-16T11:56:03 < dongs> haha
2019-03-16T11:56:07 < dongs> that thing is absolute shite
2019-03-16T11:56:09 < dongs> was it like $10?
2019-03-16T11:56:11 < antto> yes
2019-03-16T11:56:11 < jpa-> antto: no, linux
2019-03-16T11:56:20 < antto> jpa- which program do you use?
2019-03-16T11:56:20 < dongs> i got one of those before like 10 years ago
2019-03-16T11:56:24 < dongs> it had tremendous lag
2019-03-16T11:56:58 < jpa-> antto: i've tried several, but IIRC all have 100+ ms lag
2019-03-16T11:57:13 < jpa-> if you know some good one i can test it
2019-03-16T11:57:13 < antto> it came with a smol disc with sh*t, i think i didn't even touch it, i plugged it in a computer and tried to view it with vlc
2019-03-16T11:57:17 < antto> then with mplayer
2019-03-16T11:57:27 < antto> it had like 2 seconds lag, and more
2019-03-16T11:57:55 < antto> i thought "what the absolute f*ck"
2019-03-16T11:58:06 < antto> then someone told me bout guvcview
2019-03-16T11:58:13 < antto> boom, it became usable o_O
2019-03-16T11:58:56 < antto> but the actual scope still sux big time, it has to sit very low to focus, then you get flux splashes onto its plastic lens, and as you try to clean it - it gets scratched
2019-03-16T12:00:09 < antto> it's too bulky, and the focusing distance is terrible
2019-03-16T12:00:21 < antto> the stand is dumb too
2019-03-16T12:01:26 < antto> but the metal one from ebay looks kinda better, yet it's not too eggspensive
2019-03-16T12:02:10 < antto> it's less bulky too, this is good cuz my iron is hot and likes to OMNOM plastic
2019-03-16T12:03:10 < antto> i can live without the on-board screen, i plan to wire it to the comput0r and use it with guvcview like i do with the one at the job
2019-03-16T12:07:00 < jpa-> antto: looks like guvcview works reasonably well, but it's still 210 ms lag and 8 FPS speed, compared to 80ms lag and 26 FPS speed with the built-in display
2019-03-16T12:07:46 < antto> uh, resolution might play a role
2019-03-16T12:08:00 < antto> the cheap garbage one is only 640x480
2019-03-16T12:08:11 < antto> i get 25fps with it
2019-03-16T12:08:20 < antto> ..with guvcview
2019-03-16T12:08:46 < jpa-> it might just be that this one isn't optimized for fast usb streaming because it has hdmi also
2019-03-16T12:09:28 < jpa-> i tested at 640x480 because the internal display doesn't have more resolution than that either
2019-03-16T12:09:43 < jpa-> but looks like it gets the same at 1024x768
2019-03-16T12:11:30 < jpa-> my laptop's internal webcam gets 20 FPS and 60 ms, so i guess it is possible to have good ones also
2019-03-16T12:11:38 < jpa-> my experience so far has been just bad, though
2019-03-16T12:12:07 < jpa-> local hacklab has one of those cheapest-of-cheap usb microscopes and it is totally unusable at anything over 640x480
2019-03-16T12:17:11 < jpa-> https://www.elektormagazine.com/news/review-andonstar-usb-microscope/14455  seems like a useful review

2019-03-16T18:12:44 < antto> anyway, what's the problem with the usb scope? yeah it's kinda garbage (low res, very chinese, wiggling stand, etc..)
2019-03-16T18:12:52 < antto> but other than that - what?
2019-03-16T18:13:12 < englishman> you listed some great reasons there
2019-03-16T18:13:23 < englishman> why look for more reasons

2019-03-16T18:21:39 < antto> i can't read the labels on some 0805 resistors
2019-03-16T18:21:56 < antto> those which have 4 digits
2019-03-16T18:22:30 < antto> the silly garbage scope at the job fixes that, i can read 0603 resistors with it too
2019-03-16T18:22:57 < antto> and i can see shorts between nearby stuff
2019-03-16T18:23:11 < antto> or suspicious "soldering"
2019-03-16T18:24:25 < Steffannn> antto its clear you already made up your mind
2019-03-16T18:25:22 < antto> i've not decided which one to get yet
2019-03-16T18:27:00 < antto> i definately don't want one like the one at the job, that's aweful, the huge plastic "lens" at its front is perfect for collecting flux splashes and scratches.. it also likes to become white and thus reduces the image dynamic range
2019-03-16T18:27:30 < antto> the focusing distance is plain wrong
2019-03-16T18:27:38 < antto> ...for soldering
2019-03-16T18:28:13 < jadew> I used my optical one for a lot more than soldering
2019-03-16T18:30:42 < antto> last time i did soldering at home woz last year

2019-03-16T18:32:56 < jadew> actually, I'm desoldering - I'm moving components from previous prototype to the current one
2019-03-16T18:33:09 < antto> ah, nice.. ghetto
2019-03-16T18:33:31 < jadew> it's easier than lining up all the components I need to make a new board
2019-03-16T18:33:39 < jadew> + they're expensive
2019-03-16T18:34:05 < antto> no need to eggscuses, i'm ghetto too
2019-03-16T18:34:49 < Cracki> how much value in components per board?
2019-03-16T18:35:07 < Cracki> how long to transplant the valuable ones?

2019-03-16T19:36:29 < dogukan> Hi
2019-03-16T19:38:20 < dogukan> I use an stm32f303k8 nucleo board, I'm trying to make PA2 and PA3 to use alternate modes
2019-03-16T19:39:55 < dogukan> I've enabled the clock of GPIO port A using RCC, but the board stops working after "GPIOA->MODER = 0x000000F0;"
2019-03-16T20:03:30 < Cracki> define "stops working"
2019-03-16T20:05:04 < dogukan> Oh sorry my expalanation was a little vague, I just didn't know where to start
2019-03-16T20:05:37 < dogukan> gdb stops taking inputs and it does not move to the next instruction
2019-03-16T20:06:40 < Cracki> funny. setting that value merely switches two pins to analog input (rest digital input)
2019-03-16T20:06:57 < Cracki> I'd guess that something else, vital, is on that port, which you've now switched to input
2019-03-16T20:07:14 < Cracki> try |= and &= ~ to only touch the bits you want
2019-03-16T20:08:05 < Cracki> also look up "bit banding". that's a way to touch bits without read-modify-write of the whole register
2019-03-16T20:09:39 < dogukan> Cracki: thanks, only touching to the bits that I need to change using |= worked, I think other pins messes something with stlink
2019-03-16T20:09:55 < dogukan> also thank you for the suggestion
2019-03-16T20:09:59 < dogukan> n
2019-03-16T20:09:59 < Cracki> not stlink in particular
2019-03-16T20:10:18 < Cracki> it'll mess with other pins on port A. you might wanna look up what's on port A

2019-03-16T20:12:29 < Cracki> yes, looks like some of those pins have to do with JTAG or SWD
2019-03-16T20:12:34 < bitmask> someone find me a table of MS to regular package name :P
2019-03-16T20:12:50 < Cracki> MS? microsip?

2019-03-16T20:14:08 < Cracki> those are package names?

2019-03-16T23:15:01 < Cracki> that is... for newly generated packets. I hope you don't use windows for routing and want to manipulate ttl of existing packets. that would involve a little work with winpcap

2019-03-17T00:46:22 < rajkosto> i never did

2019-03-17T00:46:25 < Cracki> ah, you said cs
2019-03-17T00:46:32 < Cracki> so what's the problem then?
2019-03-17T00:46:40 < rajkosto> if you make the light fully bright and 255,255,255
2019-03-17T00:46:44 < rajkosto> its 32 bits of 1s
2019-03-17T00:46:52 < rajkosto> which matches their stop condition
2019-03-17T00:46:56 < Cracki> no idea why they'd even need an "end" frame
2019-03-17T00:47:03 < rajkosto> its when the data is latched
2019-03-17T00:48:58 < rajkosto> end of sequence marker since it makes all the leds in a series work like a huge shift register
2019-03-17T00:49:00 < Cracki> can you tolerate the "global" field not being 11111?
2019-03-17T00:49:16 < rajkosto> that loses you half the brightness
2019-03-17T00:49:24 < rajkosto> if we hackin then just make the max intensity 254,254,254

2019-03-17T00:53:03 < Cracki> wat
2019-03-17T00:53:07 < rajkosto> becase there you have fixed timing of 0 and 1

2019-03-17T00:57:25 < Cracki> inverts the order of LEDs but that's really irrelevant
2019-03-17T00:58:36 < Cracki> of course, ws2812 use a timeout to know when it's finished... which would destroy the "advantage" of having something spi-like you can just leave sitting for however long you like
2019-03-17T00:58:52 < rajkosto> advantage of spi is 30MHz clock
2019-03-17T00:59:06 < Cracki> still, even a raspi can be controlled so you get tolerable delay/jitter
2019-03-17T00:59:59 < rajkosto> only with a kernel driver
2019-03-17T01:00:12 < rajkosto> but raspbi has spi you can do the multibyte bits trick over too
2019-03-17T01:01:09 < Cracki> according to these posts, the "end frame" might require extending sometimes. looks like it's really just dummy data
2019-03-17T01:01:18 < rajkosto> thats good
2019-03-17T01:01:41 < rajkosto> i thought it used that as a trigger for end sequence
2019-03-17T01:02:45 < Cracki> dude says each chip inverts clock so the end frame causes the whole transmission to be clocked through upto 64 chips
2019-03-17T01:03:00 < Cracki> inv+delay
2019-03-17T01:03:35 < rajkosto> they should have just specified XXXXXX as end frame
2019-03-17T01:04:49 < Cracki> that whole protocol is fucked
2019-03-17T01:04:57 < Cracki> I have no idea how it would behave with more than 64 leds
2019-03-17T01:05:13 < rajkosto> make end frame LOUTER
2019-03-17T01:05:20 < Cracki> you'd have at least a full frame stretched across the string
2019-03-17T01:05:53 < Cracki> and that "end frame" or parts of it if it's extended, would be read as actual data by the first led again
2019-03-17T01:06:27 < Cracki> make:r grade bullshit
2019-03-17T01:06:56 < Cracki> can only speculate, not predict, how that thing would behave
2019-03-17T01:09:53 < rajkosto> dobt need a >64 string yet
2019-03-17T01:13:12 < Cracki> maybe that dude scoped something weird, or these LEDs actually just ignore FFFFFFFF instead of taking that for data
2019-03-17T01:13:47 < Cracki> you definitely shouldn't extend the end frame with random bits
2019-03-17T01:25:53 < englishman> rajkosto: did you figure it out
2019-03-17T01:26:02 < rajkosto> what
2019-03-17T01:26:15 < englishman> on ws2812b there is no endframe you just hold the signal low for x time
2019-03-17T01:26:24 < rajkosto> yes
2019-03-17T01:26:39 < englishman> is that apa102 datasheet m
2019-03-17T01:26:41 < englishman> ?
2019-03-17T01:26:56 < englishman> are the bits modulated at all like ws2812?
2019-03-17T01:27:01 < rajkosto> n
2019-03-17T01:27:06 < englishman> hmm
2019-03-17T01:28:14 < englishman> what is Global
2019-03-17T01:28:25 < rajkosto> current
2019-03-17T01:28:37 < englishman> so there is a string length limit
2019-03-17T01:28:47 < englishman> of 2^5?
2019-03-17T01:28:51 < rajkosto> n
2019-03-17T01:28:58 < rajkosto> its ARGB
2019-03-17T01:29:08 < englishman> that's strange
2019-03-17T01:29:11 < rajkosto> A is 111 and then 5 bits of BRIGHTNESS
2019-03-17T01:29:19 < rajkosto> this gives you way more control than just RGB
2019-03-17T01:29:34 < englishman> how so
2019-03-17T01:29:35 < rajkosto> and 111 vs 000 lets them detect stop frame
2019-03-17T01:29:44 < rajkosto> because you now have 256 * 32 brightness levels
2019-03-17T01:29:47 < englishman> I mean yes but
2019-03-17T01:30:18 < englishman> it's already 24bit rgb
2019-03-17T01:30:24 < englishman> which is p good
2019-03-17T01:30:31 < rajkosto> not when 20ma is 255,255,255
2019-03-17T01:30:33 < englishman> can you see the diff
2019-03-17T01:30:34 < rajkosto> and its blinding
2019-03-17T01:30:41 < rajkosto> the 5 bits controls the ma
2019-03-17T01:30:46 < rajkosto> the 255,255,255 controls the color
2019-03-17T01:30:52 < englishman> right
2019-03-17T01:31:08 < rajkosto> but that wasnt even the question
2019-03-17T01:31:22 < englishman> is 11111 a valid value
2019-03-17T01:31:24 < englishman> for that
2019-03-17T01:31:27 < rajkosto> yes
2019-03-17T01:31:45 < englishman> well, rip
2019-03-17T01:32:19 < englishman> guess you will have to sacrifice one bit of resolution
2019-03-17T01:32:33 < rajkosto> no it doesnt seem that the end frame is there for anything more than stuffing so ti can be anything
2019-03-17T01:32:52 < rajkosto> i dunno ill see when i get them
2019-03-17T01:33:10 < englishman> much easier to clock out at least
2019-03-17T01:33:21 < englishman> arent they way more expensive too?
2019-03-17T01:33:33 < englishman> I think I didn't buy them for that reason
2019-03-17T01:33:47 < englishman> then the 2812b mini came out
2019-03-17T01:37:59 < rajkosto> they make sk in 2020 though

2019-03-17T02:46:17 < zyp> so apparently my nfc readers are too sensitive or something
2019-03-17T02:46:27 < zyp> http://i.mechacrash.com/mkqI3iY9.mp4 <- this is pretty hilarious though
2019-03-17T02:47:20 < zyp> my best guess is that the metal panel acts as a loop around both readers and couples them together
2019-03-17T02:49:30 < zyp> I wonder if both readers are actually able to talk to the card, or if the second reader just piggybacks on the first and gets the same reply
2019-03-17T02:55:07 < Cracki> why are both lighting up?
2019-03-17T02:55:20 < Cracki> ah hm yes metal can fuck things up :>
2019-03-17T02:55:46 < zyp> they light up when they have detected a card and read the UID from it
2019-03-17T02:55:54 < Cracki> I'm sure there's some collision detection and avoidance in the protocol
2019-03-17T02:56:43 < zyp> yeah, but that's mostly for handling several tags in the range of one reader, not several readers seeing one tag at once

2019-03-17T05:06:05 < Cracki> I've been content with asus, msi, I think I had an asrock at some time as well

2019-03-17T05:16:08 < fenugrec> yea possibly
2019-03-17T05:16:52 < Cracki> I've been on an asus p8b ws since... 2012 or so? I'm so fucking glad it hasn't spazzed yet

2019-03-17T11:30:46 < ub|k> PaulFertser: ^
2019-03-17T11:35:43 < PaulFertser> ub|k: properly applied Rust should be as fast as C I guess. You can always check the generated assembly to see for yourself. I think the main reason is that learning and using Rust is more complicated than C and at the same time its advantages are mostly useless to the majority of embedded developers.
2019-03-17T11:39:55 < PaulFertser> ub|k: and those people who could enjoy Rust have usually mastered C++ enough by the time Rust came into play, so the motivation to switch is not too big as C++ is almost as powerful.
2019-03-17T11:40:12 < PaulFertser> ub|k: at least that's how I see it, take my words with a grain of salt.

2019-03-17T11:42:21 < malinus> most embedded developers has a lot of gain just switching form C->C++ imho. which is at least fully supported on most platforms.
2019-03-17T11:45:51 < PaulFertser> ub|k: have you already tried it? Or are you coming from a more CS-aimed background? Then you might enjoy the IvoryTower language (Haskell-based DSL).

2019-03-17T11:46:33 < ub|k> the thing that annoyed me the most was not the language (i like it), it was the toolchain

2019-03-17T13:18:40 < jpa-> malinus: "fully supported" .. except for STL?
2019-03-17T13:19:31 < jpa-> so you end up coding weird mix of libc and C++; atleast my experience has been that some parts of libstdc++ are unusable for embedded, and libc++ is not much better
2019-03-17T13:19:46 < karlp> is libc++ the clang one?
2019-03-17T13:19:57 < jpa-> yeah
2019-03-17T13:20:10 < malinus> jpa-: newlib-nano has all STL
2019-03-17T13:20:37 < jpa-> malinus: uh? really? to me it seems just libc
2019-03-17T13:21:10 < Steffanx> And the there is this embedded stl that isnt meant smaller mcus?
2019-03-17T13:21:30 < Steffanx> Wasnt it you who asked the maintainer of that project mr jpa- ?
2019-03-17T13:21:30 < jpa-> Steffanx: which one is that?
2019-03-17T13:21:39 < jpa-> ah, no, ustl is not meant for embedded at all
2019-03-17T13:21:58 < jpa-> it's a tiny STL-like library (not standard compliant) that is targeted for.. PCs
2019-03-17T13:22:10 < Steffanx> Oh its obsolete
2019-03-17T13:22:11 < karlp> ... why?
2019-03-17T13:22:30 < karlp> was it a compile time goal or what?
2019-03-17T13:23:07 < jpa-> i guess some people like to make small binaries for PCs
2019-03-17T13:23:09 < malinus> jpa-: hmm I'm not sure then. All I know is that I'm only including newlib-nano, and using g++. And I have all the STL. Sure it's like 300kB in the flash, but I have 64MB external flash on my target so idgaf.
2019-03-17T13:23:23 < malinus> jpa-: I'm honestly currently not sure where the STL are from if it's not the newlib-nano.
2019-03-17T13:23:37 < jpa-> malinus: ok, then you are probably using libstdc++; are you using the <iostream> part of it?
2019-03-17T13:23:42 < malinus> yes
2019-03-17T13:24:13 < jpa-> ok, then things have got better, last time I tried to include libstdc++'s iostream, it pulled in so many locale depedencies that the binary bloated to 2MB
2019-03-17T13:24:41 < malinus> This is code with iostreams, most container types, templates everywhere and a lot of c++14.
2019-03-17T13:24:50 < malinus> and it's less than 0.5MB
2019-03-17T13:24:53 < jpa-> i have used libstdc++'s <vector> etc. in 32kB flash size, but then i had to be careful what parts to use and not use
2019-03-17T13:26:02 < karlp> still _wayyyyy_ out of spac efor lots of tarkets malinus :)
2019-03-17T13:29:38 < malinus> karlp: meh, nor flsh is so cheap. But yeah stm32 are very expensive if you want a bit more flash.
2019-03-17T13:30:47 < malinus> And when going external you are gonna get at least 8MB
2019-03-17T13:31:04 < karlp> completely different project when you start putting down external flash though :)
2019-03-17T13:31:25 < rajkosto> can stm32 even XIP out of SPI flash
2019-03-17T13:31:35 < rajkosto> would need parallel
2019-03-17T13:31:37 < malinus> karlp: I'm mostly working on cortex-m with no internal flash. I don't think it's that different work-wise.
2019-03-17T13:32:08 < malinus> rajkosto: no idea, I'm on nxp which can XIP, but it also has 0.5MB ram 
2019-03-17T13:32:12 < karlp> I'm just saying your "just use c++, it' sonly 300kb, use external flash" isn't really applicable to everyone
2019-03-17T13:32:24 < rajkosto> i use c++
2019-03-17T13:32:28 < rajkosto> no extra flash needed
2019-03-17T13:32:36 < rajkosto> you cant use stdlib containers tho
2019-03-17T13:33:13 < jpa-> http://paste.dy.fi/ZVc/plain   yeah, 295kB for iostreams, with e.g. 10kB of that going into formatting support for all kind of monetary values
2019-03-17T13:33:50 < malinus> karlp: I agree. I also work on small targets (stm32f0), which has like 32kB flash :P. I wouldn't touch c++ (other than basic) on that.
2019-03-17T13:33:51 < jpa-> but lots of stuff like most containers are fine to use and don't take much flash
2019-03-17T13:34:22 < malinus> jpa-: dang what's bloaty?
2019-03-17T13:34:30 < malinus> jpa-: looks neat man

2019-03-17T13:37:07 < malinus> I guess that's what they use in VisualGDB hehe
2019-03-17T13:42:54 < jpa-> (actually, with newlib-nano for the libc side, it's only 160kB)

2019-03-17T13:44:01 < aandrew> cool utility though

2019-03-17T14:03:53 < vindicator> I'm quite flummoxed with some math I think. I started playing with timers and felt I had the math right for the prescaler and period...
2019-03-17T14:04:47 < vindicator> But when I get to the timer handler, my math seems off somewhere. The short of it I want the timer to run at 1MHz so I can deal with microseconds.
2019-03-17T14:05:41 < vindicator> When I get to the handler, I increment a counter +1 and then check if it % 1000000 == 0. This would lead me to believe I can check with it's hitting 1 second marks on time.
2019-03-17T14:06:11 < vindicator>  The thing is, it wasn't. It was more like 2 seconds and when I % 500000, it is correct.
2019-03-17T14:08:05 < vindicator> It seems to be that the SysClk is 168MHz with the APB1 prescaler is 4. So it should be 168MHz/2/1000000-1, giving me a prescaler of 83. The period is just set to 1.
2019-03-17T14:10:32 < zyp> period = 1 means you divide by 2
2019-03-17T14:10:42 < zyp> since it'll count 0, 1, 0, 1 and so on
2019-03-17T14:11:52 < zyp> if the point of the timer is to generate events at 1 MHz, I suggest instead setting PSC=0 and ARR=83
2019-03-17T14:12:26 < zyp> prescaler can do /1, main counter can't

2019-03-17T14:21:41 < vindicator> zyp: I found that when I tried that, the main loop slows down a ton. Basically I have 2 LEDS that flash. 1 from the main loop and 1 from the timer handler.
2019-03-17T14:21:43 < englishman> it works on my desk, but not across the room, haven't had any complaints so far
2019-03-17T14:22:24 < vindicator> The main loop calls HAL_GetTick and if the tick value % 1000, it's supposed to flash that LED.
2019-03-17T14:23:02 < vindicator> Then in the timer handler, the same kind of idea except using a counter and % 1000000.
2019-03-17T14:23:06 < zyp> vindicator, well, duh, when you fire interrupts at 1 MHz, of course that'll slow down everything
2019-03-17T14:23:53 < zyp> it takes quite a few cpu cycles to enter and exit an interrupt handler, and you only have 168 cycles per microsecond
2019-03-17T14:24:04 < vindicator> Figured as much. I'm guessing I should just do all of my handling in that and leave the main loop alone.
2019-03-17T14:24:17 < zyp> naturally when you only fire the interrupt at 500 kHz, you're leaving more cpu to the main loop
2019-03-17T14:25:14 < vindicator> Read the DHT-22 datasheet, I see signals are handled in terms of us and not ms.
2019-03-17T14:25:39 < zyp> huh?
2019-03-17T14:25:44 < vindicator> *I read
2019-03-17T14:25:54  * karlp laughs
2019-03-17T14:26:34 < vindicator> The datasheet for that sensor and see it has to handle stuff in terms of microseconds. That's why I was looking at timers.
2019-03-17T14:26:56 < vindicator> I am very new at this and I may be approaching it all very wrong.
2019-03-17T14:27:51 < zyp> hmm, is this a pulse length encoded signal?
2019-03-17T14:28:13 < karlp> https://github.com/karlp/karlnet/blob/master/nodes/boxcar/firmware/boxcar.c has some libopencm3 code for talking to those things
2019-03-17T14:28:18 < karlp> haven't looked at it for a while.

2019-03-17T14:28:45 < vindicator> tnx, karlp. I'll take a look.
2019-03-17T14:31:13 < zyp> glancing at the datasheet, this looks like a timer+dma problem to me
2019-03-17T14:31:44 < zyp> use input capture to grab the pulses and DMA them into the buffer, then when it's all captured just scan the buffer and translate the data
2019-03-17T14:32:00 < zyp> pretty much like dealing with ws2812b, just in reverse

2019-03-17T14:34:28 < vindicator> tnx to you too zyp. I'm saving what you said so I can reference it while I learn about it.
2019-03-17T14:36:58 < zyp> to capture the pulse length, you feed the signal into a timer channel, and then you configure the timer to reset on rising edge and capture on falling edge
2019-03-17T14:37:40 < karlp> (that was ome old ass code of mine, bsaed on porting some avr code iirc)
2019-03-17T14:37:49 < zyp> timer should be configured with PSC=84-1 and ARR=0xffff or something, that'll give you pulse length in microseconds
2019-03-17T14:37:50 < karlp> but it at least worked, and it sure didn't need 1Mhz interrupts
2019-03-17T14:38:05 < karlp> that was my first stm32 project
2019-03-17T14:38:20 < zyp> or you can set PSC lower if you want better resolution, but I expect 1 and 0 to be distinct enough that microseconds are fine
2019-03-17T14:39:00 < zyp> when you've configured that, TIMx_CHy will give you the pulse length of each pulse that arrives
2019-03-17T14:39:16 < karlp> I was just using exti irqs for the arriving edges and calculating as it came in.
2019-03-17T14:39:33 < karlp> dma+input capture is smarter, definitely
2019-03-17T14:39:42 < karlp> bit more thinking on setting it up though :)
2019-03-17T14:39:46 < zyp> and to store that, you set up a DMA job that triggers on that timer channel and copies the data from TIMx_CHy into a memory buffer
2019-03-17T14:40:18 < zyp> as far as I can see you're expecting 40 pulses, so set the DMA job to complete after 40 transfers
2019-03-17T14:40:28 < zyp> then just wait for the DMA job to finish :)
2019-03-17T14:41:01 < karlp> (and setup a timer to timeout the dma job, because thos devices are garabge.
2019-03-17T14:41:22 < zyp> once you've got that in place, you've got a nice 40-element array with pulse lengths, which you just loop over to convert to binary
2019-03-17T14:41:30 < karlp> ther's a ti/silabs cheaper 'smaller humi sensor these days that ar echeap enough
2019-03-17T14:41:30 < zyp> karlp, I'd just use the timer update event as a timeout
2019-03-17T14:41:49 < karlp> just as long as you have one somewhere :)
2019-03-17T14:42:06 < zyp> I mean on the same timer that does input capture
2019-03-17T14:42:30 < zyp> since it resets on each pulse, it should never hit update as long as pulses are arriving

2019-03-17T17:07:55 < dongs> this usb-c shit has pinout exactly inverted from how the plug is mounted
2019-03-17T17:08:01 < dongs> i wonder if they expect plug on one side of PCB and chip on another

2019-03-17T17:16:44 < rajkosto> most of them are midmount, arent they ?
2019-03-17T17:16:51 < rajkosto> and take up both sides of the pcb
2019-03-17T17:19:58 < dongs> no
2019-03-17T17:20:04 < dongs> you're thinking of paddle connector
2019-03-17T17:20:07 < dongs> that chinks solder up
2019-03-17T17:20:13 < dongs> every usbc footprint i have is top-mount
2019-03-17T17:20:45 < dongs> in either case my design cannot use mid-mount stuff because the pcb has no clearance on teh bottom
2019-03-17T17:21:09 < dongs> i wonder if I can just rename Axx/Bxx to rotate it
2019-03-17T17:21:14 < rajkosto> most of them are mid-mount cuz lol phones gotta save space
2019-03-17T17:21:17 < dongs> which would be same as turning the cable around
2019-03-17T17:21:25 < dongs> nobody buys usb-c conenctors for phones

2019-03-17T21:10:31 < jpa-> jadew`: you mean single chip without external parts or just regular any DC-DC or charge pump chip?
2019-03-17T21:10:52 < jadew`> jpa-, no external parts
2019-03-17T21:11:03 < jadew`> might have had external caps
2019-03-17T21:11:08 < jadew`> but no inductor
2019-03-17T21:11:29 < jpa-> well charge pumps have no inductors
2019-03-17T21:12:00 < jadew`> yeah, but I don't know if it was a charge pump

2019-03-17T21:17:14 < R2COM> one day when i get time i should think how to make negative voltages on IC with minimal resources
2019-03-17T21:17:56 < jpa-> maybe MAX850? though with so many caps, one might as well throw in a tiny inductor
2019-03-17T21:19:25 < R2COM> max is better if caps required are not large value ones
2019-03-17T21:19:59 < R2COM> wow they include chip topography lol
2019-03-17T21:20:09 < R2COM> why would users need that
2019-03-17T21:21:39 < jpa-> there are also "chips" like TPS826951 that have integrated inductor, but you end up paying extra to TI for putting the inductor next to chip and squirting black epoxy over it

2019-03-17T21:27:34 < Thorn> and it won't fault even if flash programming is not enabled?

2019-03-17T23:50:44 < jadew`> I think he has a plastic bar and it's coated on the outside
2019-03-17T23:50:48 < jadew`> so the dielectric is plastic

2019-03-17T23:52:03 < jadew`> but then you have to make the transition from plastic to air if you want to put it out of a horn antenna

2019-03-18T00:16:43 < rajkosto> so why do we bother with yellowish phosphor when we can just get these https://www.waveformlighting.com/d_waveform/wp-content/uploads/2018/12/realuv-strip-1024x1024.jpg and slap a dope quantum dot coating on them at any nm we want

2019-03-18T01:23:14 < Cracki> oh look they found out who jack the ripper was
2019-03-18T01:27:42 < kakimir> is 395nm useful for anything instead of 365nm?
2019-03-18T01:29:07 < jadew`> is that UV?
2019-03-18T01:29:20 < Cracki> yes it's uv
2019-03-18T01:29:32 < Cracki> 405 nm is still uv, and usable for some uv curing stuff
2019-03-18T01:29:56 < Cracki> if you want to be precise about it, figure out what material you have and its absorption properties
2019-03-18T01:30:19 < kakimir> for inspection use 365nm is a whole different world compared to 395nm
2019-03-18T01:30:37 < Cracki> uv curable stuff often responds to a wide section of uv, so anything in there should be good
2019-03-18T01:30:46 < Cracki> inspection?
2019-03-18T01:30:57 < jadew`> to check for cum stains
2019-03-18T01:31:00 < Cracki> what are you inspecting and how do 365 differ from 395 qualitatively?
2019-03-18T01:31:06 < Cracki> ic, should have known
2019-03-18T01:31:14 < kakimir> jadew` got it right
2019-03-18T01:31:14 < Cracki> it's always the same with this place
2019-03-18T01:31:36 < kakimir> I mean it shows even residues of water droplets
2019-03-18T01:32:02 < kakimir> another thing it might be useful for is NDI
2019-03-18T01:32:18 < jadew`> I guess it's a good way of finding the cleanest underwear from the pile
2019-03-18T01:32:41 < jadew`> what's NDI?
2019-03-18T01:32:42 < kakimir> nah boi
2019-03-18T01:32:48 < kakimir> non-destructive inspection
2019-03-18T01:33:00 < kakimir> using marker color
2019-03-18T01:33:10 < kakimir> it goes into cracks
2019-03-18T01:33:21 < kakimir> and lights them up in uv light
2019-03-18T01:33:35 < kakimir> ofc. there is xray and ultrasonic
2019-03-18T01:33:48 < kakimir> maybe some electronic stuff too idk.

2019-03-18T04:17:56 < R2COM> i wonder how is it with teslas
2019-03-18T04:18:10 < R2COM> although..its different story since batteries are not inside engine compartment which adds more heat
2019-03-18T04:18:15 < emeb_mac> R2COM: good question. but then they're not lead-acid batteries
2019-03-18T04:18:23 < R2COM> ahh yes

2019-03-18T04:35:59 < mawk> to include another .js file I have to litteraly create a <script> tag, append it to <body> to make the browser load it, then hook its onload event handler to know when it's done
2019-03-18T04:43:20 < R2COM> alright its enough working today, im going for the cold beer now
2019-03-18T04:44:20 < mawk> but while I have to do that I have access to advanced constructs like future/promises and stuff
2019-03-18T04:44:35 < mawk> so I do my terrible file "import" using promises
2019-03-18T04:44:39 < mawk> this language walks on the head
2019-03-18T04:47:59 < jadew`> yeah, promises can get nasty

2019-03-18T04:48:21 < emeb_mac> dongs: save money on architecture
2019-03-18T04:48:23 < jadew`> if you use them once
2019-03-18T04:48:24 < mawk> but you have promises next to terrible stuff like automatic casting or absence of import directive

2019-03-18T04:48:42 < jadew`> heh
2019-03-18T04:50:20 < jadew`> there are libraries that deal with JS importing
2019-03-18T04:50:42 < jadew`> requireJS maybe?
2019-03-18T04:51:00 < mawk> yeah
2019-03-18T04:51:01 < jadew`> there are several options, but I don't use them for my stuff
2019-03-18T04:51:06 < mawk> but I would need to import them in the same way
2019-03-18T04:51:09 < dongs> what the fuck
2019-03-18T04:51:12 < mawk> and anyway they do it the same way
2019-03-18T04:51:16 < dongs> china has so many "partial" USB-C sockets
2019-03-18T04:51:18 < jadew`> I made myself a system that deals with all of it
2019-03-18T04:51:20 < mawk> create <script>, append to <head>
2019-03-18T04:51:26 < dongs> that only break out like 6 pins for vcc/gnd/usb2.0

2019-03-18T04:56:03 < jadew`> (for the release)
2019-03-18T04:56:19 < jadew`> and then you don't have to deal with require() and waiting for the load event

2019-03-18T04:59:28 < jadew`> it's not that bad, the only downfall is that you can't wait for the promise, unless you do it from another async task

2019-03-18T05:20:10 < mawk> you can tell it's a feature made up by silicon valley engineers in their city with no crime at all
2019-03-18T05:20:25 < mawk> same for apple earpods, or more generally any kind of wireless headphone
2019-03-18T05:23:44 < Cracki> oh they have "thieving magpies" there too, but none of these aristocrats use public transport

2019-03-18T06:32:52 < bitmask> was gonna, even typed out what I might put on each label but decided it wasn't worth it, maybe as a separate label underneath though
2019-03-18T06:33:02 < bitmask> just wasnt enough room on the main label
2019-03-18T06:41:28 < Cracki> staple a foot of microfilm to it, full data sheet

2019-03-18T12:30:05 < Laurenceb_> reee muh lunix suspend is being glitchy
2019-03-18T12:30:06 < Laurenceb_> wtf
2019-03-18T12:30:47 < Laurenceb_> no
2019-03-18T12:31:04 < Laurenceb_> the issue doesnt tie up with any changes to the system
2019-03-18T12:31:15 < Laurenceb_> I wonder if its a filesystem issue :S
2019-03-18T12:34:20 < Laurenceb_> should probably fsck everything
2019-03-18T12:34:24 < Laurenceb_> ok
2019-03-18T12:34:32 < Laurenceb_> just tried it twice and it worked ok, weird
2019-03-18T12:36:37 < Laurenceb_> [  780.202679] Pid: 0, comm: swapper Tainted: G
2019-03-18T12:36:46 < Laurenceb_> only weird issue when it starts up
2019-03-18T12:42:01 < Laurenceb_> prob filesystem issue i bet
2019-03-18T12:42:16 < Laurenceb_> where is ram saved to hard drive when you suspend?
2019-03-18T12:42:24 < Laurenceb_> swap partition?
2019-03-18T12:42:33 < rajkosto> suspend keeps ram powered.
2019-03-18T12:42:38 < rajkosto> hibernate stores it to swapfile/pagefile
2019-03-18T12:43:15 < Laurenceb_> ah
2019-03-18T12:43:19 < Laurenceb_> ok thats weird
2019-03-18T12:43:40 < Laurenceb_> so when it fails the suspend light on the machine goes off
2019-03-18T12:44:02 < Laurenceb_> it usually flashes for 20s or so then goes solid
2019-03-18T12:44:13 < Laurenceb_> when it fails, it flashes for 20s then goes out

2019-03-18T12:44:25 < Laurenceb_> maybe ram is faulty?
2019-03-18T12:45:02 < rajkosto> its either firmware misbehaving
2019-03-18T12:45:05 < rajkosto> or a usb device misbheaving
2019-03-18T12:45:23 < rajkosto> can be pci express too
2019-03-18T12:45:30 < rajkosto> all the drivers need to implement suspend properly
2019-03-18T12:45:56 < Laurenceb_> rajkosto: ok
2019-03-18T12:46:18 < rajkosto> my laptop has one of the first UEFI firmwares so suspend/hibernate is broke as shit in UEFI mode
2019-03-18T12:46:20 < rajkosto> fine in DOS mode tho

2019-03-18T13:44:52 < jadew`> chinese surprise: http://5.12.183.158/stuff/gauge/25mm.jpg
2019-03-18T13:44:57 < jadew`> http://5.12.183.158/stuff/gauge/50mm.jpg
2019-03-18T13:46:33 < jadew`> the gauges are accurate
2019-03-18T13:46:56 < jadew`> and they were $4.40 together, with shipping
2019-03-18T13:48:48 < jpa-> i'm more surprised that the caliper is accurate to final digit
2019-03-18T13:48:58 < zyp> same
2019-03-18T13:50:14 < jadew`> well, the caliper is japanese :P
2019-03-18T13:50:20 < jadew`> so no surprise there
2019-03-18T13:51:41 < jpa-> yeah, but considering it doesn't have a way of applying consistent pressure unlike e.g. ratchet wheel in micrometers
2019-03-18T13:52:23 < jadew`> jpa-, varying the pressure a little doesn't seem to have any effect
2019-03-18T13:52:37 < jadew`> I'm applying about the same pressure I apply on any measurement
2019-03-18T13:52:48 < jadew`> not too much, not too little
2019-03-18T13:53:15 < jadew`> hmm, actually, it seams I can't make the last digit change no matter what
2019-03-18T13:53:26 < jpa-> maybe it's hardcoded to 0
2019-03-18T13:53:28 < jadew`> even if I press really hard or just remove my hand from it
2019-03-18T13:53:40 < jadew`> the last digit? :)
2019-03-18T13:53:47 < jpa-> if it never changes ;)
2019-03-18T13:53:57 < jadew`> heh\
2019-03-18T13:55:50 < jadew`> wish I had a micrometer to see how accurate those gauges really are
2019-03-18T13:59:29 < jadew`> I bought them on 8th December
2019-03-18T13:59:37 < jadew`> just got them in the mailbox today
2019-03-18T14:00:03 < jadew`> 3 months+
2019-03-18T14:00:09 < jadew`> that's gotta be some kind of record
2019-03-18T14:00:47 < jadew`> bought several other gauges back then
2019-03-18T14:01:07 < jadew`> I'm still waiting on the ones I really need
2019-03-18T14:18:42 < qyx> I'll need some standard calibration weights
2019-03-18T14:18:56 < qyx> 50kg or so of them
2019-03-18T14:19:11 < qyx> idk if china provides free shpping for that
2019-03-18T14:20:24 < qyx> yre you sure the post & customs office is not going to notice?
2019-03-18T14:20:38 < qyx> thats quite a lot of presents
2019-03-18T14:24:08 < jadew`> qyx, I keep seeing weight standards on ebay
2019-03-18T14:24:21 < jadew`> but I'm not sure they're that heavy
2019-03-18T14:25:07 < rajkosto> jesus the postage on 50kg
2019-03-18T14:25:08 < rajkosto> yuge
2019-03-18T14:27:11 < jadew`> qyx, does it have to be 50 kg precisely?
2019-03-18T14:27:44 < jadew`> if not, you could just measure some lifting weights on a calibrated scale and use that
2019-03-18T14:28:41 < jadew`> the good thing about weights is that they don't change their weight because of temperature/humidity or any crap like that, so it should be transferable and exact
2019-03-18T14:29:27 < BrainDamage> they do change with humidity
2019-03-18T14:29:55 < jadew`> that's true, but not by much, considering we're talking about a 50 kg weight
2019-03-18T14:29:55 < BrainDamage> just not on a scale you're interested in
2019-03-18T14:29:58 < jadew`> probably won't register
2019-03-18T14:30:02 < jadew`> yeah
2019-03-18T14:30:44 < qyx> maybe, the device will have 0-80kg range
2019-03-18T14:31:04 < qyx> some 3-point calib would be nice
2019-03-18T14:31:20 < qyx> somehow I am suspecting the circuit will not behave linearly
2019-03-18T14:31:38 < qyx> and the strain gauges too
2019-03-18T14:38:12 < jadew`> qyx, then multiple smaller weights seem like a better idea

2019-03-18T15:17:43 < rajkosto> whenever my hands are burn free i get another soldering iron burn
2019-03-18T15:19:01 < rajkosto> i usually burn myself on the soldering blobs on my desk left from shaking it down
2019-03-18T15:19:05 < rajkosto> they stay hot for a while
2019-03-18T15:19:27 < Laurenceb> I usually burn using fingernails to hold down smd parts
2019-03-18T15:19:57 < rajkosto> Haohmaru, the spong is too far away and cools the iron
2019-03-18T15:20:06 < rajkosto> shaking it to get rid of excess solder is better for fluxin
2019-03-18T15:20:18 < rajkosto> it makes blobs fall down on your desk
2019-03-18T15:24:52 < rajkosto> well as long as i dont burn my fuckin eyeball
2019-03-18T15:24:54 < rajkosto> its all good
2019-03-18T15:25:16 < rajkosto> you ever think about that if youre close to what youre solderin
2019-03-18T15:26:05 < rajkosto> have to, for precision
2019-03-18T15:26:41 < rajkosto> its flux
2019-03-18T15:27:05 < rajkosto> your eye reflex should close quick enough
2019-03-18T15:27:09 < rajkosto> for anything heavy like solder
2019-03-18T15:29:11 < rajkosto> but its in liquid form so its fine
2019-03-18T15:29:12 < rajkosto> just wash it off
2019-03-18T15:29:22 < rajkosto> dont you wash your eyeballs directly under a water stream hourly

2019-03-18T20:49:51 < upgrdman> wtf. my pic24 was hanging up at randomish times after power up after i added some LCD code. i saw some compiler warnings about missing function prototypes for my two LCD functions (which both take void, and both return void) ... after adding those function prototypes, the crashes are gone. wtf... why?!
2019-03-18T20:55:55 < Steffanx> time to look at the assembly and see what it generates?
2019-03-18T21:00:37 < Steffanx> Why you use pic24 upgrdman?
2019-03-18T21:00:43 < Steffanx> Legacy?
2019-03-18T21:00:58 < upgrdman> Steffanx, actually a new design. but i did not get to choose the mcu. 
2019-03-18T21:01:31 < upgrdman> pic24 was chosen because we needed cheap and lots of ADC channels
2019-03-18T21:01:51 < upgrdman> and the person that picked it knew PICs... so he picked a PIC :(
2019-03-18T21:01:53 < Cracki> iirc pic24 isn't as weird as the smaller ones
2019-03-18T21:02:07 < upgrdman> it's still plenty weird.
2019-03-18T21:02:13 < Cracki> that person is weird
2019-03-18T21:02:54 < Steffanx> Do you at least have a callstack etc. while debugging?
2019-03-18T21:03:59 < upgrdman> i dont think so
2019-03-18T21:04:23 < upgrdman> at least not the few times i tried finding the callstack, mplabx didn't offer one
2019-03-18T21:04:30 < Steffanx> hah.
2019-03-18T21:04:43 < upgrdman> ya. fucking rage right there.
2019-03-18T21:05:05 < upgrdman> what kind of shit fucking shit doesn't even support callstacks
2019-03-18T21:05:48 < Cracki> it *may* be that no prototype causes the compiler to infer int return type, not void
2019-03-18T21:06:08 < upgrdman> Cracki, sure but what would that cause anything to hang up?
2019-03-18T21:06:12 < Cracki> that's the least implausible thing I can think of

2019-03-19T00:11:50 < jadew`> can't wait for those summers, when you go out and all the chicks are already naked
2019-03-19T00:12:24 < kakimir> interesting
2019-03-19T00:12:38 < kakimir> first we invent clothes
2019-03-19T00:12:44 < jadew`> imagination worldwide will suffer
2019-03-19T00:12:55 < kakimir> then we invent to be nakid
2019-03-19T00:13:09 < jadew`> we're going full circle
2019-03-19T00:13:28 < kakimir> is it paradise?
2019-03-19T00:13:34 < kakimir> or hell?
2019-03-19T00:13:40 < jadew`> not sure, but I like it
2019-03-19T00:13:43 < kakimir> processing...
2019-03-19T00:15:11 < kakimir> further data queries required
2019-03-19T00:15:26 < kakimir> is it next summer?
2019-03-19T00:16:03 < jadew`> you know what would be better than that?
2019-03-19T00:16:25 < kakimir> no
2019-03-19T00:16:46 < jadew`> a culture in which men would be in "danger" of getting sexually assaulted by women when they went out
2019-03-19T00:16:56 < kakimir> nope.
2019-03-19T00:17:32 < jadew`> you go to buy groceries and come back to your wife with... "jeez... you won't believe what happened to me."
2019-03-19T00:18:21 < kakimir> oh
2019-03-19T00:18:57 < kakimir> you meant in "danger" implying men being in control of the situation after all
2019-03-19T00:19:28 < jadew`> no, I mean: "two chicks in their 20s forcefully gave me a blow job when I was loading the groceries into the trunk"
2019-03-19T00:21:54 < jadew`> this will never happen tho
2019-03-19T00:22:15 < jadew`> but the boobs out - that's already happening

2019-03-19T00:23:11 < englishman> B&K 8601 Says this battery is within 0.3% of rated capacity
2019-03-19T00:23:13 < englishman> pretty neat
2019-03-19T00:23:21 < zyp> sounds like jadew` is looking forward to get raped
2019-03-19T00:23:27 < jadew`> haha
2019-03-19T00:23:38 < jadew`> by two chicks in their 20s, yes
2019-03-19T00:24:08 < englishman> I hear that's what happened to Julian asshenge
2019-03-19T00:24:32 < qyx> PWR_CR1 |= PWR_CR1_LPMS_STOP_0 < PWR_CR1_LPMS_SHIFT; is not going to work
2019-03-19T00:24:36 < bitmask> magnetic car phone mounts a bad idea?
2019-03-19T00:25:02 < englishman> heh
2019-03-19T00:25:04 < zyp> in what sense?
2019-03-19T00:25:12 < englishman> it could
2019-03-19T00:25:14 < zyp> crashing your car is a bad idea no matter how your phone is mounted
2019-03-19T00:25:57 < bitmask> mixed reviews, some lose wireless charging, some say magnet isnt strong enough to hold their phone
2019-03-19T00:26:24 < bitmask> this one is kinda expensive but I like it: https://www.amazon.com/dp/B074Q433TL
2019-03-19T00:26:42 < zyp> http://unisynk.se/en/shop/all-products/holders/dashboard-holder/ <- just get one of these, they are awesome
2019-03-19T00:27:18 < bitmask> thats pretty bulky
2019-03-19T00:27:37 < zyp> the fuck you mean by bulky?
2019-03-19T00:28:21 < bitmask> its got a big ass
2019-03-19T00:29:02 < zyp> so what?
2019-03-19T00:29:26 < jadew`> that's not bulky at all
2019-03-19T00:29:38 < bitmask> If I didnt mind something taking up space I would have a million options, I'm leaning toward a vent option which has mixed reviews but meh
2019-03-19T00:29:54 < zyp> it's all behind the phone anyway, so it's not like it detracts any from the view
2019-03-19T00:29:59 < zyp> heh

2019-03-19T00:30:28 < jadew`> bitmask, get a smart car instead
2019-03-19T00:30:41 < zyp> IMO vent mounts are dumb
2019-03-19T00:30:44 < jadew`> you get into the car and never get your phone out of the pocket
2019-03-19T00:30:47 < bitmask> haha yea sure, I'm worried about spending $30 on a car mount but I'll just get a new car
2019-03-19T00:30:54 < bitmask> zyp why
2019-03-19T00:32:33 < zyp> because while I want the phone angled towards my face, I don't necessarily want the air angled in the same direction
2019-03-19T00:33:31 < bitmask> well most of the air will be blocked by the phone :) I just dont mind losing one vent
2019-03-19T00:33:42 < bitmask> and its in the post position for my car
2019-03-19T00:34:07 < kakimir> I'm greatly mistaken
2019-03-19T00:34:18 < zyp> the one you linked also looks like you can't angle it any
2019-03-19T00:34:34 < zyp> the one I linked has a ball joint
2019-03-19T00:35:17 < bitmask> the one I linked tilt and rotate
2019-03-19T00:35:23 < bitmask> can* I think it has a ball joint
2019-03-19T00:35:55 < zyp> also looks easy to rip out of the vent
2019-03-19T00:36:24 < bitmask> I'm not an aggressive person :)
2019-03-19T00:36:46 < bitmask> it clamps down on the fent
2019-03-19T00:36:47 < bitmask> vent
2019-03-19T00:37:36 < zyp> https://images-na.ssl-images-amazon.com/images/I/71kVl1xnjML._SL1500_.jpg <- no ball here
2019-03-19T00:37:46 < bitmask> you are looking at the wrong one?
2019-03-19T00:37:48 < zyp> just four springy prongs
2019-03-19T00:37:50 < zyp> am I?
2019-03-19T00:37:54 < englishman> looks like a great way to break your vents
2019-03-19T00:38:12 < bitmask> did you click the cheaper model?
2019-03-19T00:38:30 < zyp> hmm, right
2019-03-19T00:38:33 < bitmask> the $20 has no ball joint, the $30 one does
2019-03-19T00:38:35 < zyp> englishman, that too
2019-03-19T00:38:40 < zyp> bitmask, yeah, you're right
2019-03-19T00:45:05 < zyp> dongs, status on arcin and rohs shit?
2019-03-19T00:47:26 < englishman> in line behind my higher priority stuff i hope
2019-03-19T00:47:55 < zyp> haha
2019-03-19T00:50:17 < jadew`> bitmask, you're overthinking this, they're all crap
2019-03-19T00:50:30 < jadew`> but at the same time, they're all sort of doing the job
2019-03-19T00:50:35 < bitmask> haha yea that seems to be the consensus, I'm just gonna go with it
2019-03-19T00:50:50 < zyp> jadew`, what's «they»?
2019-03-19T00:50:56 < jadew`> zyp, the holders
2019-03-19T00:51:01 < bitmask> anything I choose is gonna have bad reviews and get shittalked in here
2019-03-19T00:51:02 < zyp> which?
2019-03-19T00:51:07 < jadew`> all holders
2019-03-19T00:51:24 < jadew`> they all have some issue you'll have to deal with
2019-03-19T00:51:44 < zyp> bitmask, you asked for advice, I gave you advice, you decided to ignore it
2019-03-19T00:51:45 < jadew`> too lose, they don't fit well, they get in the way and are not adjustable, they break easily, something
2019-03-19T00:51:48 < jadew`> there's always something
2019-03-19T00:51:58 < jadew`> I like the one you posted
2019-03-19T00:52:09 < jadew`> it looks very slick and gives access to the sides
2019-03-19T00:52:13 < zyp> yeah
2019-03-19T00:52:15 < bitmask> me too
2019-03-19T00:52:25 < bitmask> I'm too easily swayed
2019-03-19T00:53:44 < zyp> the one I have doesn't interfere with buttons on the sides, easy to operate with one hand, adjusts to the phone well and holds it good
2019-03-19T00:54:01 < zyp> and I can also reach the fingerprint sensor on the back without problems
2019-03-19T00:55:13 < jadew`> can that sensor show you your fingerprint?
2019-03-19T00:55:18 < jadew`> in vector form?
2019-03-19T00:55:25 < jadew`> or however... it detects it
2019-03-19T00:55:35 < zyp> dunno, never looked into the technicals
2019-03-19T00:55:57 < jadew`> mine has a fingerprint reader too, but I never used it
2019-03-19T00:57:19 < zyp> I didn't bother locking my phone before I got this one, fingerprint unlocking is sufficiently hassle-free that it's actually worthwhile
2019-03-19T00:57:47 < qyx> my L4 don't want to sleep
2019-03-19T00:58:17 < zyp> and then other apps like my bank app also supports fingerprint login
2019-03-19T00:58:39 < qyx> I mean it doesn't stop, it sleeps well.. at least according to its current consumption
2019-03-19T00:58:45 < jadew`> what happens if the sensor breaks?
2019-03-19T00:59:08 < jadew`> you're locked out forever?
2019-03-19T00:59:26 < zyp> no, there's always a second method
2019-03-19T00:59:34 < zyp> pin or password
2019-03-19T00:59:42 < jadew`> that's good
2019-03-19T00:59:45 < englishman> keepass has fingerprint unlock too
2019-03-19T00:59:55 < englishman> super handy
2019-03-19T00:59:56 < jadew`> can you add multiple fingerprints?
2019-03-19T01:00:00 < englishman> ofc
2019-03-19T01:00:13 < jadew`> that might not be that bad then
2019-03-19T01:00:25 < zyp> englishman, lastpass too
2019-03-19T01:00:33 < kakimir> hmm
2019-03-19T01:00:44 < kakimir> maybe bluetooth fingerprint reader
2019-03-19T01:00:57 < englishman> im still a little apprehensive about putting every single password and bank account into a passworded file in the cloud somewhere
2019-03-19T01:01:15 < jadew`> yeah, I don't do that
2019-03-19T01:01:29 < zyp> englishman, then don't
2019-03-19T01:01:37 < englishman> yeah i dont i just use keepass
2019-03-19T01:01:48 < zyp> I still keep the most important ones in my head
2019-03-19T01:01:55 < jadew`> same here
2019-03-19T01:02:14 < zyp> I only use lastpass for all the bullshit I used to reuse passwords for
2019-03-19T01:02:33 < zyp> well, not strictly true
2019-03-19T01:02:57 < zyp> I've actually got pretty much everything except my email and my bank in lastpass
2019-03-19T01:03:31 < zyp> but then again I generally don't use password login for the bank anyway
2019-03-19T01:04:41 < zyp> bank website has a 2FA thing where it shows a qr code that I scan with the bank app on the phone, and then just authenticate to the phone app with a pin code
2019-03-19T01:07:57 < zyp> there's also a second login method where I have to enter phone number and date of birth, and then bank authenticates against some logic in my sim card, which again asks me for a pin code
2019-03-19T01:08:09 < zyp> of course, if somebody steals my phone I lose both of those
2019-03-19T01:08:42 < zyp> so then I'm left with the third method, authenticating with SSN, password and a OTP from a plastic card I've got somewhere
2019-03-19T01:14:36 < bitmask> I use lastpass but am thinking of changing.  I recently had to disable 2fa because my phone broke and the automated method didnt work and so I had to email support.  One of the questions they asked me to prove it was me was to list 5 sites I have saved passwords for.  I didn't know they had such easy access to view my list of saved sites
2019-03-19T01:17:42 < zyp> AFAIK it's client side encrypted
2019-03-19T01:18:03 < zyp> so they shouldn't be able to see that
2019-03-19T01:25:18 < bitmask> thats what I thought
2019-03-19T01:25:39 < bitmask> maybe scare tactic?
2019-03-19T01:25:57 < Cracki> that or they actually keep track of at least the domains you have logins for
2019-03-19T01:26:14 < Cracki> (at least hashed...)

2019-03-19T01:46:17 < emeb> two CDC ACM on one F042
2019-03-19T01:46:32 < emeb> one going to a USART, the other to a SPI port
2019-03-19T01:46:52 < zyp> yeah, I've done that
2019-03-19T01:47:00 < emeb> cool
2019-03-19T01:47:04 < emeb> any pointers?
2019-03-19T01:47:56 < zyp> hmm, I don't have the code available at the moment, it was a tool I made at work, and now I'm home

2019-03-19T01:51:20 < zyp> the stuff I work on at work has a service port with a can bus, and I've got a shell running on each mcu sending and receiving characters over the can bus
2019-03-19T01:52:16 < zyp> at the moment I can have two mcus in a box, i.e. behind the same service port, sending can packets with different ids
2019-03-19T01:53:05 < zyp> to interface with it I picked up some readymade board with a F042, a USB plug and a can transceiver, and then I hacked up some firmware based on laks with two ACM interfaces
2019-03-19T01:53:39 < zyp> IIRC I used IAD to separate them
2019-03-19T01:53:52 < zyp> hmm, I guess it should be called ACM functions
2019-03-19T01:54:02 < zyp> since each function consists of a data and a control interface
2019-03-19T01:55:10 < emeb> right. AIUI one just sets up proper descriptors with indices of the control & data endpoints for each sub-device?
2019-03-19T01:55:47 < emeb> then direct the interrupts for the different endpoints to the proper handling code.
2019-03-19T01:56:00 < zyp> essentially, yes
2019-03-19T01:56:19 < emeb> cool. Guess I need to study that a bit more & give it a try.
2019-03-19T01:56:22 < zyp> the main purpose of IAD is to make windows happy
2019-03-19T01:56:29 < emeb> heh
2019-03-19T01:56:42 < zyp> windows is stricter about driver binding than linux
2019-03-19T01:57:00 < emeb> IIRC Mac stuff was also kinda fussy about IAD
2019-03-19T01:57:16 < emeb> at least there were some issues with it back on snow leopard.
2019-03-19T01:57:48 < zyp> IAD is an extra layer of descriptors that lets you group up a number of interface descriptors and tell the host that «these make up one function (and should thus be bound to one driver)»
2019-03-19T01:58:19 < zyp> so with IAD, windows binds drivers separately per function
2019-03-19T01:58:47 < zyp> without IAD, I think windows can only bind for either a single interface or the whole configuration
2019-03-19T01:59:01 < aandrew> yep I had to fuck with that years ago
2019-03-19T01:59:06 < zyp> and that doesn't work out so well for composite devices with multi-interface classes
2019-03-19T01:59:10 < aandrew> I just remember it being a pain
2019-03-19T01:59:23 < zyp> and yeah, I remember macos support being an issue too
2019-03-19T01:59:42 < zyp> I think macos got support in 10.8 or so
2019-03-19T02:00:03 < zyp> but I wouldn't expect anybody to actually use anything older nowadays anyway
2019-03-19T02:00:33 < zyp> hmm
2019-03-19T02:00:56 < zyp> I need to push back the IAD stuff I added to laks, should look at that at work tomorrow
2019-03-19T02:02:52 < kakimir> I feel like: carry water, chop wood
2019-03-19T02:03:04 < zyp> but now I need to find a new book to read and go to bed :)
2019-03-19T02:03:16 < kakimir> read about budhism
2019-03-19T02:04:43 < zyp> I feel like I want to read something like The Diamond Age
2019-03-19T02:05:13 < zyp> I mean, I'm almost tempted to just reread The Diamond Age, but that'd be too early
2019-03-19T02:08:00 < kakimir> I have done carrying water and chopping wood
2019-03-19T02:09:37 < emeb> IAD stuff -> laks would be appreciated.
2019-03-19T02:10:40 < zyp> recently I've been keeping a «want to read» list on goodreads, but the only books left on that list now are either books that are not published yet or unfinished trilogies
2019-03-19T02:11:25 < zyp> emeb, I'll push it tomorrow if I have time
2019-03-19T02:33:02 < emeb> zyp: thanks!

2019-03-19T13:57:06 < dongs> shit that looks like kinda white/semiclear stuff
2019-03-19T13:57:43 < dongs> https://www.aliexpress.com/item/wat/32330169293.html is it this?
2019-03-19T13:57:56 < dongs> but it kinda looks like it comes fro ma syringe maybe

2019-03-19T14:32:51 < dongs> by applying this clear magical shit
2019-03-19T14:32:51 < rajkosto> i mean you can use good flux

2019-03-19T16:25:02 < bitmask> well it def has a magnetron
2019-03-19T16:25:19 < BrainDamage> then it should have a transformer, I doubt it has a 2kV DCDC

2019-03-19T16:47:09 < BrainDamage> BrainDamage: then it should have a transformer, I doubt it has a 2kV DCDC
2019-03-19T16:47:15 < BrainDamage> apparently it does
2019-03-19T16:47:36 < jpa-> yeah, those big fets near the transformer look like smps
2019-03-19T16:47:57 < jpa-> and everything else stays the same as in normal microwave transformer, just that because input frequency is higher the transformer can be smaller
2019-03-19T16:50:22 < bitmask> so is this the transformer? whys it look so weird?

2019-03-19T16:50:28 < bitmask> its small too
2019-03-19T16:50:39 < BrainDamage> because it's an high frequency one
2019-03-19T16:50:42 < jpa-> was that photo taken with a potato?
2019-03-19T16:50:43 < BrainDamage> and high voltage
2019-03-19T16:51:02 < jpa-> it even says "inverter" in the red tape
2019-03-19T16:51:13 < BrainDamage> the dcdc lets you use high frequency, which in turns reduces the size of the inductance necessary
2019-03-19T16:51:31 < BrainDamage> the weird wire is litz wire, to reduce losses
2019-03-19T16:52:04 < bitmask> so it wont work for a battery spot welder will it :/

2019-03-19T16:53:05 < BrainDamage> ehh, it might actually work decently
2019-03-19T16:53:07 < jpa-> bitmask: you could just reverse the primary and secondary of it, and use the inverter to drive it and you should get the ~700W out of the thick coil
2019-03-19T16:53:20 < jpa-> but it might be less robust that traditional all iron and copper transformer
2019-03-19T16:53:36 < BrainDamage> yes, you even have a proper driver in the board
2019-03-19T16:53:59 < bitmask> i'll have to do some research

2019-03-19T17:07:21 < kakimir> output drivers are 5v, adc range is full voltage range too
2019-03-19T17:07:24 < rajkosto> yes but your probe is 5v tolerant anyway, and the mcu will accept 3.3v as high
2019-03-19T17:07:44 < rajkosto> if you have proper j-link etc it will have voltage shifters and a pin to detect mcu voltage

2019-03-19T17:38:37 < bdb> has anyone built a working linux-based setup for stm32 development on linux (i.e. discovery boards) using docker to isolate the deps? 
2019-03-19T17:39:14 < bdb> i've slowly been chipping away at doing this with alpine-linux as they have the stlink package in their standard community package manager repositry
2019-03-19T17:44:07 < jpa-> what deps?
2019-03-19T17:44:51 < jpa-> isn't it just    apt install gcc-arm-none-eabi openocd
2019-03-19T17:46:09 < bdb> yes, but via alpine-linux it's a bit more manual as the gcc-arm-none-eabi package (or similar) do not exist as part of the package management repos :(
2019-03-19T17:49:35 < jpa-> so just download the tar.gz and extract it somewhere and symlink to ~/bin
2019-03-19T17:51:35 < bdb> that's been the plan, i was jsut looking to see if anyone in here specifically has a working setup for a minimal docker image that has this done
2019-03-19T17:51:52 < mawk> bdb: https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads
2019-03-19T17:51:56 < mawk> no need for docker
2019-03-19T17:52:06 < mawk> it's not really the spirit here
2019-03-19T17:52:12 < mawk> you will just define PATH when needed
2019-03-19T17:52:17 < mawk> or GCC_PATH if using cubemx for instance
2019-03-19T17:52:35 < bdb> there's definitely not a need :^) it'd just be nice for portability and testing as part of CI/CD
2019-03-19T17:52:50 < bdb> fair enough though, thank you
2019-03-19T17:52:55 < mawk> maybe ansible will work better in that manner if you want repetability

2019-03-19T19:40:03 < vindicator> Can anyone explain to me why some interrupt prescalers cause my device to appear to hang? One of my experiments is, in the main loop, create a for loop to cycle through prescaler values, start the timer interrupt (which only increments a uint), the loop through a math problem.
2019-03-19T19:41:26 < rajkosto> triggering interrupts too fast means you spend all cpu time inside interrupt handlers, never in main
2019-03-19T19:41:38 < vindicator> The thing is, it isn't behaving how I would've expected. If the interrupt would hog my device, I'd expect it would happen at the lowest prescale values. But when I manually tried different values like 84, 80, 63, 42. I found that 80 and 42 would cause a hang, but 84 and 63 would not.
2019-03-19T19:42:25 < rajkosto> if you trigger while already in interrupt you dont restart the interrupt routine
2019-03-19T19:42:41 < rajkosto> (unless you have different priority levels)
2019-03-19T19:42:52 < rajkosto> i assume you have itnerrupt flag clear at the end of your routine
2019-03-19T19:44:14 < vindicator> Umm, I dunno. I'm just using the HAL. It goes a little like this: for loop{init_irq(for_prescale_value); start_irq; do math loop; stop_irq; deinit_irq}

2019-03-19T21:18:32 < rajkosto> nope they only go up to like 100oC
2019-03-19T21:18:34 < BrainDamage> you need 250+°C air to properly reflow
2019-03-19T21:18:47 < rajkosto> if you want a cheap one
2019-03-19T21:18:53 < rajkosto> get a roof shingle glue melter
2019-03-19T21:19:05 < rajkosto> but those are completely unregulated and using them is like using those 1$ chinese direct AC soldering irons

2019-03-19T21:23:31 < BrainDamage> pan on the stove may or may not work, you'll need at least a thermocouple and constantly adjust the knob to avoid overshooting the temp and burning
2019-03-19T21:24:30 < Laurenceb> a pan might just work for reflow if you "calibrate" your procedure
2019-03-19T21:24:48 < BrainDamage> yes, but you'll still need a thermocouple to do that
2019-03-19T21:25:13 < BrainDamage> to know to which level of the knob corresponds to which temp at steady state
2019-03-19T21:25:14 < Laurenceb> yeah
2019-03-19T21:25:40 < BrainDamage> it doesn't have to be precise, but just randomly setting a value you may burn the pcb
2019-03-19T21:31:37 < vindicator> Did anybody else have any thoughts why a prescaler of like 84 or 82 or 63 would still keep my device alive, but something in between like 80 would make it hang?

2019-03-19T23:47:39 < PaulFertser> mawk: so the most non-imaginative way ends in $(x - 1)^2 \ge 0$ but I hope you'll share the other answers once channers here have no more ideas. I expect at least one geometric interpretation way but it's not obvious for me :(

2019-03-19T23:53:16 < Ultrasauce> it's just a rotary axis controlled by a voice coil basically, in a servo loop

2019-03-20T00:02:00 < PaulFertser> mawk: is it like you just draw $f(x) = 
2019-03-20T00:02:40 < PaulFertser> \frac{1}{x}$ and $f(x) = -x + 2$ on a same canvas and say "see?!" ? :)
2019-03-20T00:03:10 < mawk> lol
2019-03-20T00:03:22 < mawk> not really, but if the argument is truly different from the other then yeah that counts as a solution
2019-03-20T00:03:33 < mawk> I'm not very imaginative either, I can only think of 3 different ones
2019-03-20T00:03:56 < mawk> the one you found, then the calculus one with x+1/x-2, then the hyperbolic-geometric one
2019-03-20T00:04:09 < mawk> when you let x = exp(X) which amounts to proving cosh(X) >= 0
2019-03-20T00:04:43 < mawk> which is pretty obvious from the fact that cosh²-sinh²=1 for instance
2019-03-20T00:08:00 < mawk> cosh(X) >= 1 sorry
2019-03-20T00:08:31 < mawk> hmm also you have the arithmetic geometric mean equality, that makes a 4th
2019-03-20T00:08:45 < mawk> sqrt(ab) <= (a+b)/2, here a = x and b = 1/x
2019-03-20T00:08:48 < jadew`> https://www.youtube.com/watch?v=-5R-KBa18ME
2019-03-20T00:10:25 < mawk> also for a 5th way you can exploit the fact that the logarithm is concave
2019-03-20T00:10:35 < mawk> but the proof is pretty similar to the AM-GM proof so it's a bit cheating

2019-03-20T00:23:05 < zyp> emeb, so I pushed the IAD stuff earlier today, and here's the code using it: https://paste.jvnv.net/view/0zcDo
2019-03-20T00:27:28 < vindicator> Running my little test, I found the following prescalers were bad/good: bad:71,69-67,46-45,35-34,31-26****good:84-72,66-47,44-36,33-32. I started at 84 and am completed 26.
2019-03-20T00:27:51 < emeb> zyp: cool - looking now
2019-03-20T00:28:27 < zyp> ended up doing a bunch of altium consulting today
2019-03-20T00:28:28 < vindicator> I just can't wrap my head around the intermixing numbers being good or bad. I'd get it if it was like 84-30 were good and everything <=26 was bad.
2019-03-20T00:30:18 < zyp> right after I came home from work, a guy I've worked with before called me and asked me if I wanted to come help him with some stuff, since his altium guy were on vacation
2019-03-20T00:32:17 < emeb> that's how spare time gets eaten up
2019-03-20T00:33:33 < zyp> yeah, but I don't mind the extra income :)
2019-03-20T00:34:01 < emeb> It's great if they're willing to pay. So many of the ppl asking me for help just want a favor.
2019-03-20T00:34:47 < jadew`> same here, but that stopped
2019-03-20T00:35:13 < jadew`> just do it on your terms, not theirs
2019-03-20T00:35:36 < jadew`> (do it whenever you feel like it)
2019-03-20T00:35:56 < aandrew> emeb: what, you don't do EDA for for "exposure" ?
2019-03-20T00:36:21 < zyp> I think this afternoons work is netting me around $500
2019-03-20T00:36:28 < emeb> ka-ching!
2019-03-20T00:36:31 < jadew`> nice
2019-03-20T00:36:32 < zyp> I mean, before tax
2019-03-20T00:36:40 < zyp> but still, that's decent
2019-03-20T00:37:00 < emeb> I actually got a nice little quick gig a few weeks back
2019-03-20T00:37:28 < emeb> some dude wanted help doing some audio thing in FPGA. I looked at it and told him he could just use an F7. His software ppl disagreed.
2019-03-20T00:37:39 < zyp> heh :)
2019-03-20T00:37:53 < emeb> I wrote up a report explaining why. Suddenly they all seemed OK w/ it.
2019-03-20T00:38:05 < emeb> Got ~$1k for it.
2019-03-20T00:38:11 < zyp> nice
2019-03-20T00:38:42 < zyp> guess they saved a bunch not having to deal with the fpga
2019-03-20T00:38:46 < emeb> yeah
2019-03-20T00:39:05 < emeb> I even put them in touch w/ someone who got it coded up for them and it's working now.
2019-03-20T00:39:19 < emeb> (didn't want to do it myself)
2019-03-20T00:39:20 < zyp> anyway, have fun with the USB code, I'm sleepy so I'm going to bed now
2019-03-20T00:39:26 < emeb> gn
2019-03-20T00:39:36 < zyp> just message me if anything comes up and I'll get back to you when I have time
2019-03-20T00:39:59 < emeb> sure. need to study it some - not fully familiar w/ all the laks infrastructure.

2019-03-20T11:31:41 < zyp> picking shitty chips and having problems with them, typical kakimir 
2019-03-20T11:32:23 < rajkosto> add reset_config none
2019-03-20T11:32:26 < rajkosto> to end of openocd config
2019-03-20T11:32:52 < kakimir> reset_config none separate
2019-03-20T11:33:17 < kakimir> what is that separate thing?
2019-03-20T11:33:47 < kakimir> it just seems that openocd support needs some manual work
2019-03-20T11:34:32 < rajkosto> separate means trst is independent of srst
2019-03-20T11:34:34 < rajkosto> SWD doesnt use it anyway
2019-03-20T11:34:45 < kakimir> okay
2019-03-20T11:35:36 < kakimir> zyp: some chips have reset pin and are still a shitshow
2019-03-20T11:35:54 < zyp> so what? you can solve that by not picking them for your project :p
2019-03-20T11:37:18 < rajkosto> where do i find a strip using these diodes https://ae01.alicdn.com/kf/HTB1xf_NHVXXXXbzXpXXq6xXFXXX1/5m-a-roll-a-lot-rgbw-led-strip-light-4chip-5050-led-per-meter-24V-12V.jpg but with no resistors and all the LEDs wired serially
2019-03-20T11:40:32 < kakimir> rajkosto: the trick was not to use reset at all
2019-03-20T11:40:41 < kakimir> no reset init
2019-03-20T11:40:46 < kakimir> nothing with reset in it
2019-03-20T11:41:26 < kakimir> if that would maybe require reset handler in my program code
2019-03-20T11:41:58 < rajkosto> no, the reset is there so that no matter what software its currently executing, it resets to a known state
2019-03-20T11:42:01 < rajkosto> has nothing to do with user code
2019-03-20T11:43:28 < kakimir> hmm got the session running
2019-03-20T11:43:40 < kakimir> it goes straight to hell

2019-03-20T12:10:48 < kakimir> what do you make out of this
2019-03-20T12:13:52 < kakimir> I should just bui infineon jlink
2019-03-20T12:14:50 < kakimir> isolated probe, jlink, inexpensive, certainly works just plug an play
2019-03-20T12:17:15 < kakimir> this chips provides 2 modes of debugging boots
2019-03-20T12:17:41 < kakimir> actually 4 if single wire debuggings are included
2019-03-20T12:18:05 < kakimir> but basically ones with halt after reset and without
2019-03-20T12:18:16 < kakimir> I programmed it with HAR
2019-03-20T12:18:52 < kakimir> maybe I should go w/o HAR

2019-03-20T13:48:22 < kakimir> maybe jlink debugging will make my headache go away
2019-03-20T13:57:48 < kakimir> do you think that just 2 resistor dividers would be okay for level conversion?

2019-03-20T14:09:30 < rajkosto> you need a transistor for bidir
2019-03-20T14:10:16 < kakimir> why wouldn't it work?

2019-03-20T14:26:21 < qyx> dongs: re chip inductors, I used 1uH/200mA 0805 for tps6282518, with Vin=4.75 it saturates during the first switching cycle
2019-03-20T14:26:38 < qyx> which generates an orbital spike on the output
2019-03-20T14:26:43 < dongs> nice
2019-03-20T14:27:17 < qyx> for such light load (<1mA) replacing with a 0603 10uH wire-wound is much better
2019-03-20T14:27:48 < qyx> they are also quite cheap
2019-03-20T14:28:01 < dongs> isnt that tps some tiny thing
2019-03-20T14:28:15 < dongs> ya it is

2019-03-20T16:43:01 < dongs> zyp, excel?
2019-03-20T16:43:15 < zyp> the guy I did some altium consulting for yesterday were pulling up BOMs and stuff in excel and it annoyed me a lot that they all got stuck in the same window
2019-03-20T16:43:24 < zyp> ya
2019-03-20T16:43:25 < dongs> https://www.ablebits.com/office-addins-blog/2013/05/31/excel-workbooks-separate-windows/ there's this but i was too lazy to figure it out

2019-03-20T16:43:36 < zyp> idk what version
2019-03-20T16:43:40 < dongs> so i jsut ended up maximizing and restoring each MDI sheet to a random size inside the main window
2019-03-20T16:43:47 < dongs> it breaks alt-tab and shit in all sorts of awful ways but wahtever
2019-03-20T16:43:59 < dongs> i just needed to make soem sheets for smart grid paste into altium
2019-03-20T16:44:05 < dongs> to make component with a bunch of pins
2019-03-20T16:44:23 < dongs> i'm sure all versions of excel are awful

2019-03-20T20:50:39 < bitmask> hmm, is it worth taking apart another laser printer for the laser, motors and whatnot
2019-03-20T20:54:04 < Cracki> why the laser? it's low powered
2019-03-20T20:54:33 < Cracki> question is, what do you want to _build_?
2019-03-20T20:54:56 < Cracki> if you wanna play, take a scanner apart
2019-03-20T20:55:20 < kakimir> when you are taking printers appart and not knowing what to do with it
2019-03-20T20:55:27 < Cracki> those contact image sensors (no real depth) are fun to poke
2019-03-20T20:55:30 < kakimir> you need to start prioritizing
2019-03-20T20:55:48 < kakimir> that is why I have a pile of printers
2019-03-20T20:56:42 < Cracki> ink jet printers have encoders and strips in them. nicely reusable for other servo positioning uses
2019-03-20T21:03:02 < bitmask> well I got the printers from the recycling center, I was hoping they might have a little bit of toner left but they dont
2019-03-20T21:03:07 < Steffanx> I see atmel gear, please avoid that next time kakimir
2019-03-20T21:03:13 < bitmask> so I figured id take em apart before bringing them back :)

2019-03-21T02:39:34 < Cracki> and here you see them placing a big qfp, and having to manually fuck with a feeder because the tape jammed https://www.youtube.com/watch?v=LjGCP9bvGNc
2019-03-21T02:41:55 < jadew`> still looks helpful
2019-03-21T02:42:20 < Cracki> most helpful for spitting down lots of birdfeed on lots of boards
2019-03-21T02:42:26 < Cracki> the setup needs love
2019-03-21T02:45:13 < jadew`> I still haven't found out
2019-03-21T02:45:21 < jadew`> any idea if the CE mark needs to be on the PCB?
2019-03-21T02:45:26 < jadew`> I know the WEEE one doesn't
2019-03-21T02:45:34 < zyp> uh, doubt it
2019-03-21T02:45:47 < jadew`> zyp, that's what I thought
2019-03-21T02:45:53 < jadew`> so only on the enclosure
2019-03-21T02:45:54 < Cracki> visible to buyer?
2019-03-21T02:46:07 < jadew`> no, the PCB won't be visible

2019-03-21T03:13:25 < zyp> good
2019-03-21T03:14:01 < con3> zyp: does not look like it's gonna be easy, but pretty sure I'll have a better understanding
2019-03-21T03:14:23 < zyp> eh, depends on how you approach it
2019-03-21T03:14:38 < zyp> can't speak for ll, but I've never used cube or hal
2019-03-21T03:14:44 < zyp> never used ll either
2019-03-21T03:15:12 < con3> so bare metal or..?
2019-03-21T03:16:42 < zyp> you can do that, although I figure you'd prefer one of the other existing alternatives
2019-03-21T03:16:46 < zyp> e.g. libopencm3
2019-03-21T03:17:02 < con3> ah is that what you've been using?
2019-03-21T03:17:17 < zyp> no, I wrote my own
2019-03-21T03:19:52 < con3> think I'll try and fight ll for now :p

2019-03-21T05:00:30 < emeb_mac> but cube is nice for exploring pinouts, setting up clocks / etc.
2019-03-21T05:00:48 < emeb_mac> and hal provides reasonably usable infrastructure.

2019-03-21T15:28:54 < jadew`> when I said input leakage current, I didn't mean that that current is leaking from my signal into the comparator
2019-03-21T15:28:58 < jadew`> it's leaking out of the comparator
2019-03-21T15:29:13 < jadew`> not sure if that came across
2019-03-21T15:29:21 < jadew`> and it's why I was surprised to find it was so high
2019-03-21T15:30:27 < karlp> leaking out where?
2019-03-21T15:30:53 < jadew`> into the input circuitry, which for this test was a simple resistor connected to ground

2019-03-21T15:37:21 < jadew`> in a 100k it would be 20 mV (several times the input offset voltage)
2019-03-21T15:39:38 < BrainDamage> jadew`: look at the schematic of the comparator
2019-03-21T15:40:15 < BrainDamage> npn need current to flow inside the base to turn them
2019-03-21T15:40:22 < BrainDamage> pnp need current to flow outside

2019-03-21T15:41:08 < BrainDamage> the internal current gens force current through the emitters, which turn them on, but that current has to split between base and collector with the beta relation
2019-03-21T15:41:14 < jadew`> ok, that makes sense

2019-03-21T15:41:49 < BrainDamage> there's low noise input transistors with hybrid tech using jfets
2019-03-21T15:42:08 < BrainDamage> yes, that pile of shit of jfet is still useful because they can be built on bjt processes
2019-03-21T15:42:24 < BrainDamage> and they have extremely low noise and rather low input current

2019-03-21T15:45:57 < jadew`> is there any use for bjt comparators? it's the first time I use one and it seems rather limited
2019-03-21T15:46:15 < jadew`> do they excel at anything in particular?
2019-03-21T15:46:31 < BrainDamage> they have lower 1/f noise than jfet based ones
2019-03-21T15:46:38 < BrainDamage> and way way lower 1/f noise than mos
2019-03-21T15:46:56 < BrainDamage> so if your input signal is very slow moving and weak, they win

2019-03-21T17:13:01 < jadew`> is the slew rate of a sine usually calculated at 90%?
2019-03-21T17:13:23 < jadew`> not sure where I got that info from, just want to make sure I didn't pull it out of my ass
2019-03-21T17:13:41 < kakimir> slew rate of a sine
2019-03-21T17:14:10 < kakimir> all I know is that there is no such rounded numbers about sine
2019-03-21T17:15:59 < jadew`> I think it's related to signals in general
2019-03-21T17:16:08 < jadew`> and it's 80%
2019-03-21T17:16:17 < jadew`> it's measured from 10% to 90%
2019-03-21T17:16:23 < jadew`> so an 80% span
2019-03-21T17:18:23 < jadew`> that means that a 10 MHz sine would have a 7 MV/s slew rate?
2019-03-21T17:20:54 < BrainDamage> the derivative of a sin(omega*t) is omega*cos(omega*t), max(|cos|) = 1, which leaves 2pi*omega
2019-03-21T17:20:59 < BrainDamage> bleh, omega
2019-03-21T17:21:07 < mawk> why 2pi ?
2019-03-21T17:21:07 < mawk> ah
2019-03-21T17:21:29 < BrainDamage> so 2pif
2019-03-21T17:21:56 < BrainDamage> and multiply that by the amplitude
2019-03-21T17:22:02 < mawk> pif means nose in slang french
2019-03-21T17:22:07 < Laurenceb> https://www.youtube.com/watch?v=L7zia2HqOOc
2019-03-21T17:22:54 < jadew`> BrainDamage, that doesn't takes into account the percentage you're looking at
2019-03-21T17:22:57 < jadew`> it's peak to peak
2019-03-21T17:23:07 < BrainDamage> wat
2019-03-21T17:23:18 < BrainDamage> it's the worst slew rate you can find in a sine
2019-03-21T17:23:32 < BrainDamage> if you want at a particular point, evaluate it for a specific t
2019-03-21T17:23:40 < BrainDamage>  omega*cos(omega*t) < here
2019-03-21T17:24:00 < jadew`> I need it for a range around the middle
2019-03-21T17:24:04 < jadew`> in this case +- 40%

2019-03-21T17:27:10 < arc_phasor> good ones, being the ones with more functionality
2019-03-21T17:27:39 < qyx> allocate the better ones first and then use the others for such things?
2019-03-21T17:28:03 < arc_phasor> i did that, but now i'm finding in stm32cube that i used a bunch that are for ADC and stuff

2019-03-21T17:29:49 < qyx> but there may be peripherals like fsmc, sdio, dcmi
2019-03-21T17:30:06 < jadew`> 1 / sin(0.8 * tau / 4 * freq) that's the final formula I came up with
2019-03-21T17:30:10 < jadew`> but I'm not sure it's correct
2019-03-21T17:30:42 < jadew`> and you multiply that by vpp

2019-03-21T17:43:13 < arc_phasor> like a firm in india just has a bunch of work they can re-use
2019-03-21T17:43:34 < kakimir> well that is the benefit of selling solutions instead of work
2019-03-21T17:43:43 < kakimir> you do thing once
2019-03-21T17:43:59 < kakimir> then just can it for customer
2019-03-21T17:44:23 < kakimir> charge as if you had to do it all from scratch
2019-03-21T17:44:34 < arc_phasor> step 3. profit
2019-03-21T17:44:40 < kakimir> indeed
2019-03-21T17:45:32 < arc_phasor> STM32 nucleo question, what is the purpose of the MCO ?
2019-03-21T17:45:51 < arc_phasor> What's an example of use for this?
2019-03-21T17:46:02 < Laurenceb> clock out?
2019-03-21T17:46:21 < arc_phasor> master clock out, so like an 8MHz signal just chillin on a line?
2019-03-21T17:46:28 < Laurenceb> loads of stuff
2019-03-21T17:46:36 < Laurenceb> e.g. radio applications
2019-03-21T17:46:45 < Laurenceb> or synchronising a second stm32
2019-03-21T17:47:04 < Laurenceb> or just reducing the number of crystals you need on your board
2019-03-21T17:47:21 < arc_phasor> copy that, sounds like i can disable for now
2019-03-21T17:48:28 < arc_phasor> uhh guess not, disabling the gpio in stm32cube just screwed with the clock page
2019-03-21T17:49:12 < dongs> arc_phasor: you can drive another STM32 with it, y ou can use it to confirm your shit is actually running at the speed you think its running etc.
2019-03-21T17:49:22 < dongs> also clock out for whatever stuff that might need a clock
2019-03-21T17:54:23 < arc_phasor> i really gotta spend a day and do a deep dive on this clock situation
2019-03-21T17:55:34 < karlp> if turning off mco "screwed up" your clock page, it was because you chose to select exporting the clock, just don't do that
2019-03-21T18:01:48 < qyx> I am quite surprised by the LSE-to-MSI PLL functionality
2019-03-21T18:01:53 < qyx> it actually works
2019-03-21T18:04:19 < arc_phasor> ohhh, maybe the st-link part of the nucleo is supplying the clock
2019-03-21T18:04:34 < arc_phasor> actually, it's MCO, so that wouldn't make sense
2019-03-21T18:05:10 < arc_phasor> karlp: where can i deselect exporting the clock, just reset the pin on the GPIO page?
2019-03-21T18:06:15 < mawk> the stlink is supplying the clock arc_phasor ye

2019-03-21T18:08:35 < karlp> mawk, that wouldn't be relevant for configuring your own,
2019-03-21T18:08:46 < karlp> and that's the MCO pin of the stlink host side, not MCO pin of the target.
2019-03-21T18:08:59 < mawk> I was responding to this: [17:04:19] <arc_phasor> ohhh, maybe the st-link part of the nucleo is supplying the clock
2019-03-21T18:09:14 < arc_phasor> i'm designing a board without the st-link, so what's a typical setup if there's no master clock supplied?
2019-03-21T18:09:26 < arc_phasor> i still have the LSE crystal for use with an RTC
2019-03-21T18:09:32 < mawk> you see on the nucleo boards there's en empty place for the HSE crystal
2019-03-21T18:09:33 < karlp> either HSI, MSI (asyou're on an L series part) or HSE.
2019-03-21T18:09:36 < dongs> use internal osc if you dont need usb / if your part can go full speed off i nternal
2019-03-21T18:09:54 < karlp> every part can go full speed off internal dongs, wat you talking about.
2019-03-21T18:10:24 < arc_phasor> mawk: i do see that, neato, that makes sense
2019-03-21T18:10:48 < mawk> but as dongs said you can maybe use the HSI unless you're doing USB or something else that needs a precise thing
2019-03-21T18:11:05 < dongs> karlp: F1 surely cant
2019-03-21T18:11:13 < dongs> 64mhz off HSI, 72 w/HSE
2019-03-21T18:11:18 < dongs> cuz it halves HSI before going to pll
2019-03-21T18:11:21 < dongs> and pll can only go x16
2019-03-21T18:12:03 < karlp> f1 sux, f1 did wtc, whatevs
2019-03-21T18:12:11 < qyx> who uses f1
2019-03-21T18:12:30 < karlp> all the other ones I'v elooked at can do whatever multiplier on pll they like so it all works off hsi to max speed unless you need accuracy for usb.
2019-03-21T18:12:41 < dongs> yep
2019-03-21T18:12:45 < qyx> and for usart
2019-03-21T18:12:46 < qyx> and can
2019-03-21T18:12:47 < dongs> im certainly not using F1 in anything new
2019-03-21T18:12:51 < dongs> mostly qfn F0s
2019-03-21T18:13:09 < dongs> you dont need more than HSI for usart
2019-03-21T18:13:13 < dongs> thats for sure
2019-03-21T18:14:45 < arc_phasor> either way, shouldn't need a hardware change, since no matter whats it's generating it internally, right?
2019-03-21T18:14:48 < qyx> I came across a few occurences of garbage caused by HSI
2019-03-21T18:15:01 < karlp> qyx: wat?
2019-03-21T18:15:22 < karlp> at what sorts of speeds?
2019-03-21T18:15:33 < qyx> I mean the HSI was off in some marginal conditions it caused occasional garbage
2019-03-21T18:15:37 < qyx> >115200
2019-03-21T18:15:58 < karlp> hrm, I've only had garbage from no pullups on rx, but haven't seen that for ages.
2019-03-21T18:16:22 < qyx> it was usual on AVR too :>
2019-03-21T18:16:45 < karlp> well, yes, that's a different periph,
2019-03-21T18:16:51 < karlp> on stm32 tough?
2019-03-21T18:17:01 < karlp> the uart periph on avr even says how much error it would have for some baud rates.
2019-03-21T18:17:08 < karlp> that's not relevant for stm32 uart periphs
2019-03-21T18:17:15 < qyx> yes, but I haven't seen it for longer times
2019-03-21T18:17:27 < qyx> but for 250k CAN I encountered it yesterday for example
2019-03-21T18:17:34 < qyx> but thats also different
2019-03-21T18:17:36 < qyx> I agree
2019-03-21T18:17:49 < karlp> "no need for hse for uart shitz" is still what I' dstand by.
2019-03-21T18:18:19 < qyx> we can conclude that unless proven otherwise
2019-03-21T18:18:51 < mawk> arc_phasor: on the nucleo the high speed clock is taken from the stlink, depending on your configuration; but you don't need a hardware change no, if you plan on using the HSI clock
2019-03-21T18:19:00 < mawk> just configure it right
2019-03-21T18:19:29 < arc_phasor> ok cool. thanks
2019-03-21T18:20:06 < mawk> you can play with it in cubemx, there's a nice graphical tool to configure clock sources, PLL, CSS, various dividers and multipliers, etc
2019-03-21T18:21:46 < qyx> if you are designing a board just for playing or you are doing it for the first time, better reserve the footprint for the HSE crystal
2019-03-21T18:21:55 < qyx> you ma regret omitting it later
2019-03-21T18:21:58 < qyx> *may
2019-03-21T18:23:07 < qyx> pick some common package (eg. 3225) + 2 caps
2019-03-21T18:26:29 < qyx> there should be a list of common fuckups in zypsnips
2019-03-21T18:26:52 < arc_phasor> haha, that might be a good idea then
2019-03-21T18:27:22 < arc_phasor> i do have a 400khz i2c and 115200 uart being used
2019-03-21T18:27:45 < karlp> you don't need a crystal for that.
2019-03-21T18:27:46 < arc_phasor> i'm using the stm32 as like a programmable pmic type of thing, communicating with a battery charge ic and fuel gauge

2019-03-21T21:26:11 < jpa-> but i could do some tricks with timers
2019-03-21T21:26:56 < jpa-> it's easy to get the P and I terms, but then i'd need to add them together to get pwm output; and when either can be negative it gets complex

2019-03-21T21:31:03 < jpa-> yeah

2019-03-21T21:36:05 < Steffanx> for stm8
2019-03-21T21:36:35 < zyp> «it's okay that it's shit, because this other shit is even worse»
2019-03-21T21:36:45 < zyp> no thanks
2019-03-21T21:36:54 < jpa-> i'd prefer pic10f and assembly!
2019-03-21T21:36:57 < Steffanx> That's not what i said.
2019-03-21T21:37:16 < zyp> jpa-, enjoy that banked memory :)
2019-03-21T21:37:25 < Steffanx> but i dont know the quality of iar, cosmic or whatever. so i dont know if its shitty :P
2019-03-21T21:38:13 < jpa-> zyp: not on pic10f, it only has 64 bytes
2019-03-21T21:38:19 < zyp> oh, haha
2019-03-21T21:38:51 < jpa-> or actually many models like 10f200 only have 16 bytes

2019-03-21T21:40:53 < jpa-> http://jpa.kapsi.fi/svn/uunimittari/transmitter_sw/   this code to read from TMP100 and send over 433MHz took almost all of the 256 instructions
2019-03-21T21:41:17 < zyp> :)
2019-03-21T21:41:32 < jpa-> more reliable than STM32 i2c though
2019-03-21T21:41:45 < zyp> :D
2019-03-21T21:41:56 < Steffanx> half of it is taken by moving stuff around the w register. how great.
2019-03-21T21:42:23 < jpa-> Steffanx: but none for stack pushing
2019-03-21T21:42:27 < zyp> well, duh
2019-03-21T21:42:37 < zyp> it's not «the w register», w is _the_ register :p

2019-03-21T21:43:19 < Steffanx> I need it to be 3.3V
2019-03-21T21:43:45 < bitmask> NO!
2019-03-21T21:43:45 < kakimir> I think I have used that chip
2019-03-21T21:43:55 < Steffanx> then i cannot decide bitmask.
2019-03-21T21:43:57 < bitmask> the chip itself doesnt matter, just the format
2019-03-21T21:44:04 < kakimir> hey bitmask
2019-03-21T21:44:06 < zyp> bitmask, so when is your store opening?
2019-03-21T21:44:06 < bitmask> hey
2019-03-21T21:44:08 < kakimir> I have labeller
2019-03-21T21:44:09 < jpa-> yeah, must be 3.3V
2019-03-21T21:44:15 < kakimir> 2 labellers
2019-03-21T21:44:19 < kakimir> one does paper things
2019-03-21T21:44:22 < bitmask> store? no store
2019-03-21T21:44:25 < kakimir> one does plastic dings
2019-03-21T21:44:25 < Steffanx> id go for the lower botton one bitmask

2019-03-21T21:44:39 < jpa-> and  LP2985AIM5-3.3/NOPB
2019-03-21T21:44:49 < Steffanx> lol
2019-03-21T21:44:51 < zyp> bitmask, no no no, these labels are obviously for marking stuff you hang on store shelves
2019-03-21T21:44:51 < bitmask> kakimir I got a plastic one, I feel like the lamination will last longer
2019-03-21T21:45:16 < bitmask> jpa- see you didnt use 3.3v there
2019-03-21T21:45:20 < bitmask> because its not in the name
2019-03-21T21:45:26 < jpa-> bitmask: yeah, but i used the name
2019-03-21T21:45:41 < bitmask> hmmm
2019-03-21T21:45:52 < jpa-> if 300mV is "ultra low dropout", what will you call the 150mV ones?
2019-03-21T21:46:00 < zyp> breaking up the name into two lines seems like a pain
2019-03-21T21:46:31 < Steffanx> oh the aim5x is part of the name. thought it was some other random placeholder.
2019-03-21T21:46:41 < Steffanx> i wouldnt break it up indeed.
2019-03-21T21:46:57 < jpa-> and i agree that these labels belong on those e-ink pricetags
2019-03-21T21:46:59 < bitmask> its just the detailed stuff on the second line, so when you are looking for what you want its easier to browse through just looking for the main name
2019-03-21T21:48:05 < jpa-> why not put also the pinout on the label?
2019-03-21T21:48:08 < zyp> bitmask, but really, if you're going through this much pain to label everything you might as well open a store, since you'll have all the work done anyway :p
2019-03-21T21:48:29 < bitmask> yea thats all the work :P
2019-03-21T21:48:39 < jpa-> you can come label all my parts also
2019-03-21T21:48:42 < bitmask> it really isn't that hard to label things
2019-03-21T21:48:50 < Steffanx> Want to visit dutchland too?
2019-03-21T21:48:57 < Steffanx> i can pay in stroopwafels.
2019-03-21T21:49:03 < jpa-> i know what part of Steffanx i'd label first!
2019-03-21T21:49:09 < bitmask> so you guys complain about how I'm doing it then want me to come do it for you? haha no
2019-03-21T21:49:17 < Steffanx> my waffle packs jpa- duh

2019-03-21T22:06:39 < bitmask> yea that must be nice
2019-03-21T22:06:52 < kakimir> got the thing for like 30euros
2019-03-21T22:07:01 < bitmask> the low resolution would be a lot nicer if it could do grayscale
2019-03-21T22:07:17 < bitmask> but its good enough

2019-03-21T22:14:08 < kakimir> ?
2019-03-21T22:14:38 < kakimir> my hobby projekt still needs to be done
2019-03-21T22:14:42 < Cracki> you've found the zerocrossing when you touch it to the wires and it doesn't explode in your face
2019-03-21T22:14:54 < kakimir> it has zero crossing detection
2019-03-21T22:15:00 < kakimir> a couple of opamps
2019-03-21T22:15:17 < kakimir> another one is offset buffer
2019-03-21T22:15:17 < s34n> yes. mains
2019-03-21T22:15:35 < Cracki> are you qualified to work with mains voltage?
2019-03-21T22:15:43 < jpa-> s34n: put optoisolator so that it gives out 1 on positive semicycle and 0 on negative semicycle, set EXTI interrupt on rising / falling edge
2019-03-21T22:15:44 < s34n> no
2019-03-21T22:15:56 < Cracki> then get someone who is. it's safer.
2019-03-21T22:16:00 < kakimir> jpa-: wow that is simple :o
2019-03-21T22:16:25 < kakimir> you need clamping diodes to it and stuff though
2019-03-21T22:16:29 < jpa-> https://i.imgsafe.org/c8749757f6.png  something like this
2019-03-21T22:16:36 < kakimir> if you want to have anything close to accurate
2019-03-21T22:16:42 < jpa-> so a diode antiparallel to clamp the voltage and series resistors to limit current
2019-03-21T22:17:07 < karlp> better hope there's no harmonics on your line too.

2019-03-21T22:19:49 < kakimir> pins are transformer secondary
2019-03-21T22:25:35 < s34n> Cracki: I appreciate your warning. I'm only working on paper.
2019-03-21T22:27:55 < zyp> optoisolator trick makes sense if the rest of your circuit is gonna be galvanically isolated from the powerline
2019-03-21T22:28:15 < zyp> otherwise just use a comparator and some voltage dividers
2019-03-21T22:28:28 < zyp> some stm32 have comparators built in, so you only need the resistors
2019-03-21T22:29:50 < s34n> jpa-: doesn't the H11AA1 have six pins?
2019-03-21T22:30:36 < s34n> zyp: that's what I thought
2019-03-21T22:30:54 < s34n> do blue pills have comparators?
2019-03-21T22:31:20 < s34n> F103 specifically
2019-03-21T22:32:44 < karlp> no, it's a garabge old product.
2019-03-21T22:32:51 < jpa-> s34n: only four of them are connected
2019-03-21T22:32:52 < karlp> sto psupporting bluepill manufacturing
2019-03-21T22:33:32 < zyp> s34n, no, but F3 does
2019-03-21T22:34:31 < s34n> karlp: ok. is there a ~$2 F3 board?
2019-03-21T22:35:07 < s34n> karlp: that's a serious question. +/- $5
2019-03-21T22:35:28 < karlp> s34n: there never will be as long as people keep buying bluepills
2019-03-21T22:35:58 < jpa-> s34n: do you understand the difference between galvanically isolated and non-isolated?
2019-03-21T22:38:06 < s34n> jpa-: no. galvanically isolated to me means there is no conductivity between them
2019-03-21T22:38:48 < jpa-> i'd recommend the optoisolator then, because it's harder to make fatal mistakes with it
2019-03-21T22:38:49 < s34n> karlp: $10? $20? what's out there?
2019-03-21T22:41:29 < s34n> jpa-: In my case I think they are equally dangerous :)
2019-03-21T22:43:18 < s34n> I was hoping to build a board to stack on the (word I can't mention out of respect for karlp) so that all the main power would be there and it fed 3.3 through the header
2019-03-21T22:44:33 < karlp> you can use them, just dont' expect all the newer peripherals.
2019-03-21T22:44:48 < s34n> That board would only get connected to power when it was out of reach
2019-03-21T22:44:53 < karlp> are you actyually trying to do an ac offline power supply? or just zero crossing detection?
2019-03-21T22:45:16 < s34n> I'm doing an ac motor controller

2019-03-21T22:53:57 < s34n> karlp: The dev boards I've seen for F3 are substantially bigger and maybe $40
2019-03-21T22:54:25 < jpa-> f3 discovery is cheaper than that
2019-03-21T22:54:29 < s34n> karlp: for a one-off project, the $40 isn't too killer, but the size is ... unfortunate
2019-03-21T22:54:53 < jpa-> but what's the point? it's not like external opamp or optoisolator costs more than 50 cents
2019-03-21T22:55:18 < jpa-> and you know, you could just solder the mcu directly to your pcb

2019-03-21T23:04:24 < kakimir> it's just cozy
2019-03-21T23:04:38 < kakimir> no effort
2019-03-21T23:06:19 < Cracki> I still have a devboard for the new ones lying around... meant to explore these mini LUTs and new event "system"
2019-03-21T23:06:49 < karlp> hrm, nanosleep works perfectly well in C.  what's wrong with this lua binding :|
2019-03-21T23:08:21 < kakimir> Cracki: I didn't go all way to using LUT
2019-03-21T23:08:37 < kakimir> just routed event to evout pin and it did the trick
2019-03-21T23:09:12 < kakimir> it took like 20ns or so from event to having falling edge on EVOUT pin
2019-03-21T23:09:16 < kakimir> pretty useful glue
2019-03-21T23:09:31 < Cracki> since megas (or tinys) have no quadrature decoding and you have to waste interrupt handling time, I was hoping the new tinys can be "wired" to do quadrature counting
2019-03-21T23:09:50 < Cracki> 20ns you say? that's fast
2019-03-21T23:09:58 < Cracki> is that unclocked or what?
2019-03-21T23:10:23 < kakimir> I think it's like direct logic connection
2019-03-21T23:10:33 < Cracki> nice
2019-03-21T23:10:37 < kakimir> the system just gates it to pin driver
2019-03-21T23:11:34 < kakimir> LUT is just truth table to glue into that line if you need ORs or ANDs or something
2019-03-21T23:11:54 < Cracki> yeh, I figure I'll need that to evaluate a quadrature signal properly
2019-03-21T23:12:04 < kakimir> interesting
2019-03-21T23:12:21 < kakimir> why not just SPI?
2019-03-21T23:12:24 < Cracki> haven't seen a solution yet, haven't fully thought it through either
2019-03-21T23:12:35 < Cracki> why spi? spi can't decode quadrature signal
2019-03-21T23:12:38 < Cracki> or can it
2019-03-21T23:13:11 < Cracki> I'd like to see all four edges of course :P
2019-03-21T23:13:31 < Cracki> ah, there it is http://ww1.microchip.com/downloads/en/AppNotes/00002434A.pdf
2019-03-21T23:13:45 < Cracki> I think i read that before and thought it a little wasteful
2019-03-21T23:16:53 < Cracki> ah, I guess they need one timer solely for turning edges into pulses
2019-03-21T23:22:43 < Cracki> they even need _two_ timers for edge to pulse
2019-03-21T23:22:55 < Cracki> oh boy that's not economic
2019-03-21T23:23:04 < kakimir> what is not?
2019-03-21T23:23:21 < Cracki> the peripherals they need to decode quadrature...
2019-03-21T23:23:27 < kakimir> well
2019-03-21T23:23:29 < Cracki> they occupy three timers in total
2019-03-21T23:23:32 < kakimir> with small micro
2019-03-21T23:23:40 < kakimir> you need to waste resources efficiently
2019-03-21T23:23:50 < Cracki> with a little more fixed logic, they could have done this without abusing two timers
2019-03-21T23:24:25 < kakimir> isn't there like a pile of more timers?
2019-03-21T23:24:41 < kakimir> and you can split timers too
2019-03-21T23:24:47 < kakimir> into 2
2019-03-21T23:24:50 < Cracki> not sure, unlikely
2019-03-21T23:24:54 < Cracki> or can you
2019-03-21T23:25:35 < Cracki> random sheet open: says it has four timers plus rtc, so not that many
2019-03-21T23:25:50 < Cracki> and only one type of timer can be split
2019-03-21T23:26:07 < s34n> does an f1 do quadtrature?
2019-03-21T23:26:11 < Cracki> yes
2019-03-21T23:26:20 < Cracki> "encoder" mode
2019-03-21T23:26:32 < Cracki> just hook it up, poke registers, done
2019-03-21T23:26:43 < Cracki> *ram locations :>
2019-03-21T23:26:53 < kakimir> I thought that quadrature requires only spi
2019-03-21T23:27:05 < Cracki> you are confused
2019-03-21T23:27:27 < Cracki> quadrature is two digital signals, it's not a protocol or bus or anything
2019-03-21T23:28:00 < Cracki> if you know of a trick to abuse an spi receiver to decode quadrature, I would love to hear it
2019-03-21T23:28:21 < kakimir> I thought there was a trick
2019-03-21T23:28:35 < kakimir> yeah I should play more
2019-03-21T23:28:46 < Cracki> there are probably chips that decode quadrature and give you the count via spi interface
2019-03-21T23:29:30 < Cracki> no spi receiver is able to count in any way that's useful for counting encoder pulses
2019-03-21T23:30:01 < kakimir> oki
2019-03-21T23:32:10 < mawk> oki
2019-03-21T23:33:31 < Cracki> you could use one as clock and the other as MISO, but then you'd have a single sample per electrical rotation, and you'd have to count ones and zeros on the received "data"
2019-03-21T23:33:54 < Cracki> (single sample instead of all four edges)
2019-03-21T23:34:54 < kakimir> yes I figured
2019-03-21T23:35:08 < kakimir> interrupt on clock pin
2019-03-21T23:35:37 < kakimir> then read register - if it's even possible
2019-03-21T23:35:44 < Cracki> if you do that, just put extis on both signals and do the logic yourself in the handler

2019-03-21T23:35:52 < kakimir> yes
2019-03-21T23:36:05 < Cracki> that's the simplest thing to do and even a tiny can do it
2019-03-21T23:36:24 < kakimir> it's zero sum game to do it with spi
2019-03-21T23:36:49 < Cracki> and hogs an spi peripheral
2019-03-21T23:37:54 < Cracki> same reason I'm unhappy with the new tinys having to abuse two timers solely for their edge-to-pulse behavior that could simply have been a fixed function to the LUT stuff or event system
2019-03-21T23:38:31 < kakimir> it's a general purpose chip
2019-03-21T23:38:45 < kakimir> trend is to not have dedicated peripherals
2019-03-21T23:39:23 < kakimir> just multifunction ones that you sew together to perform operation
2019-03-21T23:39:31 < Cracki> the trend I see is trying to declutter peripherals, make them more generally useful
2019-03-21T23:39:48 < Cracki> can't replace peripherals by millions of interrupts
2019-03-21T23:41:06 < kakimir> but you can by millions of events
2019-03-21T23:41:23 < kakimir> everything is a event

2019-03-21T23:42:05 < kakimir> that is the trend
2019-03-21T23:42:39 < kakimir> you can do more not restricted to legacy shape of peripherals
2019-03-21T23:42:58 < kakimir> and they probably make silicon more efficient too idk.
2019-03-21T23:43:40 < Cracki> sure I love events
2019-03-21T23:45:04 < Cracki> that's still for the benefit of dedicated peripherals, that can go longer without involving the core

2019-03-22T05:32:22 < Cracki> always have a spare
2019-03-22T05:32:35 < jadew`> I do
2019-03-22T05:32:39 < jadew`> and I can repair it anyway
2019-03-22T05:32:58 < jadew`> just annoyed because I've been at this for 9 hours+ and I'm getting nowhere
2019-03-22T05:32:59 < Cracki> how fried is it? got input buffer?
2019-03-22T05:33:09 < jadew`> yeah, the input buffer is gone
2019-03-22T05:33:11 < Cracki> perhaps take a break, nap, or sleep
2019-03-22T05:33:24 < jadew`> yeah, I guess I'll do that
2019-03-22T05:34:00 < jadew`> I'm trying to talk to an IC and I've copied the SPI signal exactly like it comes out of the dev board and it's just not working when it comes out of my MCU
2019-03-22T05:34:07 < jadew`> if I feed it from the dev board it works
2019-03-22T05:34:50 < jadew`> what's worst, is that only some configuration values seem to have issues (they only work when sent from the dev board)
2019-03-22T05:35:05 < Cracki> funny
2019-03-22T05:35:18 < Cracki> clock polarity ok? maybe timing/freq is marginal?
2019-03-22T05:35:22 < jadew`> and again, I checked, double checked, even implemented a dumb soft SPI, so it looks exactly like the stupid shit coming out of the dev board
2019-03-22T05:35:28 < Cracki> or maybe voltages are off
2019-03-22T05:35:45 < jadew`> same voltages
2019-03-22T05:35:47 < Cracki> maybe it does something besides SPI
2019-03-22T05:36:06 < jadew`> there should be lots of room for error for frequency, but I matched the timings almost exactly
2019-03-22T05:36:15 < jadew`> it doesn't, there are only 3 wires
2019-03-22T05:36:27 < Cracki> slopes look similar too? maybe it's crapping out because of ringing or whatever
2019-03-22T05:37:08 < jadew`> yeah, it looks the same, there is some weirdness but coming from the devboard, because the signal comes over a couple of wires
2019-03-22T05:37:15 < jadew`> it's just... impossible
2019-03-22T05:37:23 < Cracki> copies exactly exactly? perhaps it expects some funny delays between bytes
2019-03-22T05:37:23 < jadew`> maybe those free energy freaks are onto something
2019-03-22T05:37:33 < Cracki> maybe they are
2019-03-22T05:37:51 < jadew`> I've added all the delays
2019-03-22T05:37:56 < jadew`> even the delays between bits
2019-03-22T05:38:07 < jadew`> even the delays between clock and the data edges
2019-03-22T05:38:13 < jadew`> it just won't fucking work
2019-03-22T05:38:29 < jadew`> anyway, I have to watch something funny and go to bed
2019-03-22T05:38:36 < jadew`> wasted a whole day on this
2019-03-22T05:38:41 < Cracki> fun :P
2019-03-22T05:38:54 < jadew`> yeah...
2019-03-22T05:39:12 < Cracki> I suspect it's a clock phase issue and _they_ made an error that works, marginally
2019-03-22T05:39:58 < Cracki> just wild speculation. tomorrow the planets will be aligned differently
2019-03-22T05:40:16 < jadew`> I hope so

2019-03-22T09:48:33 < dongs> hmm
2019-03-22T09:48:36 < dongs> this toshitba diode has 2.7 Vf
2019-03-22T09:48:41 < dongs> package similar too
2019-03-22T09:49:00 < dongs> anyway, i looked at hte board again, can't be zener cuz the bar on package is towards final output
2019-03-22T09:49:27 < dongs> so its regular diode setup in series for the purpose of dropping output and preventing current from outside from coming in

2019-03-22T12:02:55 < karlp> don't suppose anyone here knows what signal I could send to test handling the interrupted case here? http://pubs.opengroup.org/onlinepubs/9699919799/functions/nanosleep.html
2019-03-22T12:03:16 < karlp> all the signals I've tried just kill the process or are ignored.
2019-03-22T12:08:21 < PaulFertser> karlp: but do you actually register a handler for the signal, e.g. USR1?
2019-03-22T12:12:22 < karlp> no, I've got no handlers,
2019-03-22T12:12:30 < karlp> it is only for handlers in my own appication then?
2019-03-22T12:12:44 < karlp> ah, that makes sense.
2019-03-22T12:15:10 < PaulFertser> You can also try SIGSTOP/SIGCONT without registering a handler I guess.

2019-03-22T13:16:57 < mawk> any signal works as long as your register a signal handler and don't exit the process in it
2019-03-22T13:17:14 < mawk> and you didn't specify SA_RESTART when setting up the signal handler
2019-03-22T13:18:35 < mawk> even though I'm not sure about the SA_RESTART behavior, it is for syscalls that take a "long" time, like read() or write(), probably nanosleep() is one of these
2019-03-22T13:19:22 < mawk> blocking or ignoring the signal isn't good enough, you need a handler
2019-03-22T13:20:53 < karlp> yeah,  10:18:32           karlp | just registerd a sigusr1 handler, worked fine.

2019-03-22T15:46:14 < karlp> wat?
2019-03-22T15:46:15 < jpa-> or maybe it's not supported even on hardware level
2019-03-22T15:46:34 < karlp> the profiling in oocd does that without stopping it, one tick.

2019-03-22T16:13:10 < kakimir> does i2c have like minimum speed?
2019-03-22T16:13:21 < kakimir> I wonder if you could go all way to soundcard range
2019-03-22T16:13:51 < Cracki> it has clock stretching so probably
2019-03-22T16:14:18 < Cracki> you want to abuse an audio DAC for driving i2c?

2019-03-22T16:15:28 < aandrew> I2c works to DC
2019-03-22T16:15:42 < aandrew> SMBus has a minimum speed 
2019-03-22T16:15:53 < kakimir> maybe just throw raspberry pi to it and have it to monitor i2c

2019-03-22T16:17:15 < kakimir> I have never used anything less than 100khz
2019-03-22T16:17:23 < kakimir> and 96 doesn't cut it

2019-03-22T16:23:41 < unclenorton> kakimir: hmmmmm, it the led lights up with sda but not with scl
2019-03-22T16:23:50 < Cracki> timed read whole port, write uart; or abuse SPI input, feed it clock from a timer
2019-03-22T16:23:57 < unclenorton> i don't see anything wrong with the AFR setup tho
2019-03-22T16:24:12 < Cracki> lights up meaning you see vcc or you see ground?
2019-03-22T16:24:23 < unclenorton> i see ground
2019-03-22T16:24:42 < Cracki> so... sda wiggles, but scl is dead?
2019-03-22T16:24:48 < unclenorton> apparently
2019-03-22T16:24:59 < Cracki> hm, that's progress
2019-03-22T16:25:20 < kakimir> just don't push too much of current thru there
2019-03-22T16:25:43 < unclenorton> i have a 10k resistor in series with the led so i'm ok
2019-03-22T16:25:50 < kakimir> okay
2019-03-22T16:25:52 < kakimir> indeed
2019-03-22T16:26:06 < Cracki> ... now I'm curious how well an arduino with abused SPI would work as a 1ch LA...
2019-03-22T16:26:58 < mawk> what's wrong with using gpio ?
2019-03-22T16:27:21 < Thorn> spacewalk https://www.youtube.com/watch?v=_9qTXUP6qkg
2019-03-22T16:28:18 < kakimir> mawk: too easy
2019-03-22T16:30:15 < Cracki> mawk, GPIO would be the way for 2-8 ch, full port read. _fast_ 1ch read is probably best with SPI because it already handles the bit packing/shifting for you
2019-03-22T16:31:08 < mawk> I see
2019-03-22T16:31:27 < mawk> maybe using DMA and the ARM bitband you can do the bit packing automatically
2019-03-22T16:31:31 < mawk> without involving the CPU
2019-03-22T16:31:36 < kakimir> oh fuckin fet is a goner again

2019-03-22T16:38:50 < kakimir> source pin has +5V
2019-03-22T16:39:01 < kakimir> gate is switched between 5V and 0V
2019-03-22T16:39:16 < kakimir> drain rises to only 2-2.5volts
2019-03-22T16:39:38 < mawk> yeah
2019-03-22T16:39:42 < mawk> isn't it a normal figure ?
2019-03-22T16:39:56 < mawk> it's not a bjt
2019-03-22T16:41:52 < kakimir> drain should rise to 5volts ofc
2019-03-22T16:42:04 < kakimir> there is only milliamps of load
2019-03-22T16:44:49  * karlp wonders why anyone would want a fast single channel LA.
2019-03-22T16:45:04 < kakimir> if I look at Rds(on) it requires 250mA for such voltage drop
2019-03-22T16:46:16 < mawk> characteristics could be a bit random
2019-03-22T16:46:26 < zyp> karlp, presumably to capture fast async serial traffic, without having to pay for more channels than required
2019-03-22T16:46:59 < unclenorton> I seriously have no idea why SCL isn't working, it should be SDA on PB9 and SCL on PB8 and if SDA works then SCL should too but it doesn't
2019-03-22T16:48:15 < kakimir> I think I have heard similar problem before
2019-03-22T16:49:50 < kakimir> here
2019-03-22T16:51:06 < kakimir> I think "catphis" or such nick here had problem of SCL staying low
2019-03-22T16:51:30 < mawk> catphish
2019-03-22T16:51:34 < unclenorton> But it's staying high not low

2019-03-22T16:53:02 < mawk> no, but I can grep logs
2019-03-22T16:53:21 < kakimir> catphish and SCL or i2c
2019-03-22T16:54:27 < mawk> no useful result
2019-03-22T16:54:50 < kakimir> unclenorton: is the line OK?
2019-03-22T16:54:54 < kakimir> I mean not shorted
2019-03-22T16:55:21 < kakimir> I think it was the case with catphish case he did some QFN package stuff first time and surelly it was shorted
2019-03-22T16:55:26 < unclenorton> hmm let me check
2019-03-22T16:55:46 < kakimir> or was it even some actual copper sort
2019-03-22T16:55:54 < kakimir> idk. cannot remember
2019-03-22T16:56:00 < kakimir> *short
2019-03-22T16:56:25 < unclenorton> no it's just floating
2019-03-22T16:58:12 < kakimir> I mean SCL should stay high and SDA too
2019-03-22T16:58:16 < kakimir> when the line is idle
2019-03-22T16:58:51 < unclenorton> do i need external pullups?
2019-03-22T16:59:19 < unclenorton> i tried with external pullups aswell but it still didn't wprk
2019-03-22T16:59:23 < unclenorton> work
2019-03-22T17:00:21 < kakimir> yes
2019-03-22T17:00:26 < kakimir> you need external pullups
2019-03-22T17:00:41 < kakimir> i2c devices are open collector drivers
2019-03-22T17:00:53 < kakimir> line should be conditioned externally
2019-03-22T17:01:14 < kakimir> what resistor size you used?
2019-03-22T17:01:18 < unclenorton> 10k
2019-03-22T17:02:10 < kakimir> go lower
2019-03-22T17:02:29 < unclenorton> 1k?
2019-03-22T17:02:30 < kakimir> 2k2 3k3 4k7 do you have them?
2019-03-22T17:02:50 < unclenorton> well that still won't make scl work, will it?
2019-03-22T17:03:09 < kakimir> lines should be both low if you don't have resistors
2019-03-22T17:03:38 < kakimir> idk but 10k can be too much in some cases
2019-03-22T17:04:14 < kakimir> what speed you are using?
2019-03-22T17:04:16 < kakimir> 100khz?

2019-03-22T17:04:44 < unclenorton> it should be 400khz
2019-03-22T17:04:45 < kakimir> lines should be floating actuaclly in idle but nothing is atleast driving them high
2019-03-22T17:05:03 < unclenorton> but scl wasn't being pulled low
2019-03-22T17:05:26 < unclenorton> it still won't work if i use pullups
2019-03-22T17:05:31 < kakimir> 400khz and 10k - I'm not totally sure about that
2019-03-22T17:05:45 < kakimir> i2c pros what do you think?
2019-03-22T17:06:48 < unclenorton> yeah but that doesn't matter right now because scl isn't being pulled low

2019-03-22T17:08:05 < mawk> also kakimir for your fet maybe I don't understand your circuit, but shouldn't you apply the 5V to drain ?
2019-03-22T17:08:14 < mawk> isn't it what Rds(on) is measuring
2019-03-22T17:08:19 < mawk> or maybe it's symmetric and that doesn't matter
2019-03-22T17:08:35 < kakimir> you can do anything with fets
2019-03-22T17:10:46 < Cracki> 10k is a little weak, usual values are 2-5k
2019-03-22T17:11:05 < Cracki> back away from the problem.
2019-03-22T17:11:13 < Cracki> disable i2c, try wiggling that pin as gpio
2019-03-22T17:11:18 < Cracki> does that work?
2019-03-22T17:12:05 < Cracki> drain is where the "positrons" come out of, so the "lower" end

2019-03-22T17:14:47 < kakimir> I'm not sure if you should even see it with a led
2019-03-22T17:15:18 < kakimir> especially for low data quantities it stays low pretty short total period

2019-03-22T17:17:11 < Cracki> make it send continuously?
2019-03-22T17:17:30 < kakimir> but his code gets hung to flag check
2019-03-22T17:17:34 < Cracki> or check basic function of the pin by using it as a gpio
2019-03-22T17:17:40 < kakimir> TXIS or something
2019-03-22T17:17:40 < Cracki> flag check?
2019-03-22T17:17:45 < Cracki> oy vey
2019-03-22T17:17:50 < unclenorton> hmm, if i look at I2C1->ISR after sending start then i see that the arbitration lost bit is set
2019-03-22T17:18:06 < kakimir> interesting
2019-03-22T17:18:15 < Cracki> and you're sure both lines have pullups?
2019-03-22T17:18:41 < unclenorton> oh wait i forgot that
2019-03-22T17:18:46 < Cracki> orly
2019-03-22T17:18:48 < kakimir> if you only have 10k
2019-03-22T17:18:55 < Cracki> 10k is weak but should do the job
2019-03-22T17:18:59 < kakimir> just pile 3 of them
2019-03-22T17:19:03 < kakimir> in series
2019-03-22T17:19:09 < Cracki> parallel you mean
2019-03-22T17:19:11 < Cracki> series is 30k
2019-03-22T17:19:12 < kakimir> yes
2019-03-22T17:19:42 < unclenorton> yep it was the pullup
2019-03-22T17:19:46 < unclenorton> no arbitration lost now
2019-03-22T17:20:21 < karlp> dude, we mentioned pullups like a dozen times
2019-03-22T17:21:09 < unclenorton> it's really hard for me to use pullups right now because it isn't on a breadboard
2019-03-22T17:21:13 < unclenorton> i have to hold the resistors
2019-03-22T17:22:03 < karlp> at least try the onboard pullups, but if you're doing i2c, you _need_ pullups, and onboard ones might not be enough
2019-03-22T17:22:09 < karlp> very unlikely to be enough for 400k anyway
2019-03-22T17:23:21 < kakimir> it's not reliable at least
2019-03-22T17:23:35 < kakimir> oh I measured +5v line
2019-03-22T17:23:45 < unclenorton> okay apparently stm32's internal pullups are enough
2019-03-22T17:23:53 < kakimir> it seems that fet was okay
2019-03-22T17:24:04 < unclenorton> good enough for testing at least
2019-03-22T17:24:06 < kakimir> there is current going thru that fet
2019-03-22T17:24:57 < Cracki> "enough"/ theyre high value, so weak. not usable for faster speeds
2019-03-22T17:27:01 < kakimir> there is no way those are enough for 400khz
2019-03-22T17:27:51 < Cracki> holding Rs to traces is useless. you need a breadboard and/or solder some wires to the board
2019-03-22T17:28:58 < kakimir> weak pullup equivalent resistor: typ. 40kOhm
2019-03-22T17:30:10 < kakimir> sure it can be hacky way to get something done really slowly when you want to save in component count

2019-03-22T17:34:25 < Cracki> because you're dicking around
2019-03-22T17:34:34 < Cracki> pullups have to be the right range
2019-03-22T17:34:50 < Cracki> you CAN NOT CONTINUE pressing loose components against board traces
2019-03-22T17:34:52 < unclenorton> pullups won't affect whether scl is pulled low or not
2019-03-22T17:35:01 < Cracki> *shrug8
2019-03-22T17:35:15 < unclenorton> sda was working without pullups, why wasn't scl?
2019-03-22T17:35:31 < Cracki> you're getting a nack because it's expecting the line to have the proper pullups
2019-03-22T17:35:55 < Cracki> again, you should test basic function of the pin by wiggling it as GPIO
2019-03-22T17:36:17 < Cracki> verifying that excludes a bunch of problems easily

2019-03-22T17:37:26 < unclenorton> i am getting a nack because it isn't sending a clock signal
2019-03-22T17:37:39 < Cracki> and how do you see htat
2019-03-22T17:37:43 < kakimir> indeed
2019-03-22T17:37:47 < Cracki> you have no scope and no LA
2019-03-22T17:38:05 < Cracki> with a scope you would see the absolutely horrible edges caused by these weak pullups
2019-03-22T17:38:14 < Cracki> it _has_ to be in the range of 2-5 kOhm
2019-03-22T17:38:20 < Cracki> builtin doesn't cut it
2019-03-22T17:38:28 < kakimir> simple reason is that slave cannot see shit and wont respond
2019-03-22T17:38:35 < kakimir> -> nack
2019-03-22T17:39:19 < Cracki> nack is when the slave does nothing at all
2019-03-22T17:39:47 < Cracki> ack is when the slave actively pulls the line to signal reception
2019-03-22T17:39:52 < unclenorton> i put a led on sda and scl, the led on sda lit up and the one on scl didn't
2019-03-22T17:40:09 < Cracki> do I need to ask you again to _test_ the pin as a GPIO?
2019-03-22T17:40:24 < Cracki> or do you know for a fact that the pin works?
2019-03-22T17:41:20 < Cracki> if it senses "bus contention", it might sense that on either pin, and then not drive any pin at all
2019-03-22T17:41:53 < Cracki> if you hope to get current out of a pin with 30k pullup, it'll be too little to get a random LED to light up
2019-03-22T17:42:21 < Cracki> it can certainly sink current because i2c is open drain, i.e. "shorts" to ground
2019-03-22T17:42:59 < Cracki> you need to actually follow some of the advice because that's the only advice that can be given

2019-03-22T17:45:15 < Cracki> great, that's useful information
2019-03-22T17:45:24 < Cracki> now, a bunch of things can cause that.
2019-03-22T17:46:54 < Cracki> either you're testing it wrong (it's not sourcing or sinking enough current to satisfy your led), or the setup lacks a step (give some clock to the port etc...), or some special function is overriding its gpio feature and holding it low
2019-03-22T17:47:24 < unclenorton> i'm setting up pb8 and pb9 exactly the same way and pb9 works but pb8 doesn't
2019-03-22T17:47:47 < Cracki> now you can start suspecting physical failure
2019-03-22T17:47:55 < Cracki> maybe a bad solder joint
2019-03-22T17:48:05 < Cracki> maybe the pin got fried by a short or something

2019-03-22T20:14:07 < kakimir> please tell
2019-03-22T20:15:31 < unclenorton> https://media.digikey.com/Photos/STMicro%20Photos/MFG_NUCLEO.jpg this is what my nucleo board looks like
2019-03-22T20:15:39 < unclenorton> on the right you can see male headers
2019-03-22T20:15:49 < unclenorton> and next to them on the left are arduino headers
2019-03-22T20:15:56 < unclenorton> and they are not aligned
2019-03-22T20:16:14 < unclenorton> so i was plugging my scl and sda pins into the 2 top left pins of the male header
2019-03-22T20:17:11 < unclenorton> basically i was plugging my scl and sda into pins 1 and 3 when i should have been plugging them into 3 and 5
2019-03-22T20:18:54 < zyp> fun
2019-03-22T20:19:11 < kakimir> so

2019-03-22T21:35:58 < kakimir> The Dirt
2019-03-22T21:36:26 < Cracki> a movie about dirt? where does it take place?
2019-03-22T21:36:57 < Steffanx>  Biography, Comedy, Drama
2019-03-22T21:36:59 < Steffanx> meh
2019-03-22T21:37:11 < kakimir> 7.8 imdb
2019-03-22T21:37:50 < kakimir> 96% google users
2019-03-22T21:38:05 < kakimir> 46% rotten tomatoes
2019-03-22T21:38:09 < Cracki> kek
2019-03-22T21:38:24 < kakimir> it's a ok
2019-03-22T21:38:28 < Cracki> one "finds" things nobody else bothered to pick up
2019-03-22T21:40:08 < kakimir> it was literally a front page of netflix
2019-03-22T21:40:15 < Cracki> >netflix
2019-03-22T21:40:26 < Cracki> would you like me to teach you torrenting?
2019-03-22T21:40:51 < Cracki> (1) buy vpn (2) set up client (3) the pirate bay ARRR
2019-03-22T21:41:44 < Cracki> you only see ads for stuff that isn't selling by mere word of mouth
2019-03-22T21:41:52 < kakimir> that top100 in piratebay is just gay
2019-03-22T21:42:09 < Cracki> https://www.xach.com/moviecharts/2019.html
2019-03-22T21:42:23 < Cracki> the top X by box office is gay as well
2019-03-22T21:42:40 < kakimir> certainly
2019-03-22T21:42:52 < kakimir> 90% gay
2019-03-22T21:43:20 < Cracki> perhaps https://www.xach.com/moviecharts/1988.html
2019-03-22T21:43:52 < Cracki> they don't make movies like they used to
2019-03-22T21:45:18 < kakimir> I mean
2019-03-22T21:45:51 < kakimir> box office != how good the movie is
2019-03-22T21:45:59 < kakimir> there is some correlation
2019-03-22T21:46:10 < Cracki> indeed it's a weak correlation
2019-03-22T21:46:23 < Cracki> correlates better with how much money they dumped into ADS
2019-03-22T21:47:04 < Cracki> how how many seats they bought to make the numbers look better, as is the case with captain cat lady

2019-03-22T22:07:46 < kakimir> thing about top box office movie nowdays it's all based in strict format
2019-03-22T22:07:55 < kakimir> it's all the same
2019-03-22T22:08:53 < upgrdman> if anyone else has a surface pro, just a tip: if you experience weird intermittent glitches on an external monitor, or if your volume +/- buttons stop working and instead act like you press ctrl-alt-del, you need to clean out the docking connector. a small paintbrush/acidbrush to get any dust out, then use some deoxit on the male docking connector. problem went away and works like new again.

2019-03-22T23:28:31 < jadew> but works with anything, if I send the data from the dev board
2019-03-22T23:28:35 < Steffanx> somehow it send me to https://www.youtube.com/watch?v=0JQ0xnJyb0A :P
2019-03-22T23:28:40 < Steffanx> @ qyx
2019-03-22T23:28:47 < jadew> also, it works if I just send it a couple of times
2019-03-22T23:29:02 < jadew> I've checked the signal lines multiple times, they're ok
2019-03-22T23:29:32 < jadew> I've done the SPI in software, to mimic exactly what comes out of the dev board and the results are the same

2019-03-23T15:33:19 < bitmask> how does mesh wifi work?
2019-03-23T15:34:11 < bitmask> I'm guessing both/all routers need to support it?
2019-03-23T15:35:59 < englishman> found Laurenceb_ http://www.eusprig.org/index.htm
2019-03-23T15:36:26 < englishman> except for the "european" part
2019-03-23T15:36:48 < englishman> http://www.eusprig.org/horror-stories.htm
2019-03-23T15:52:32 < Cracki> bitmask, what kind of mesh? 802.11 itself supports "peer to peer" between stations, but nobody really uses that. the "mesh" networking that's more common is for routers to have a wireless backbone instead of wired, which is sensibly done in 5 ghz or even higher
2019-03-23T15:53:41 < Cracki> how that backbone is done, I have no idea. you might glean practical details from a german thing called "freifunk"
2019-03-23T15:53:50 -!- basker_ [~basker@177.10.81.41] has quit [Read error: Connection reset by peer]
2019-03-23T15:54:31 < bitmask> well I definitely want the routers connected through wired, most likely a moca adapter
2019-03-23T15:54:51 < bitmask> so maybe I'll just have a router for upstairs and one for downstairs
2019-03-23T15:54:54 < Cracki> most actually freifunk works with a wired uplink: you plug it into your LAN (cable/DSL uplink)
2019-03-23T15:55:06 < Cracki>  ah that?
2019-03-23T15:55:19 < Cracki> turn the boxes into bridges maybe
2019-03-23T15:55:31 < Cracki> and let whatever does the LAN handle dhcp and stuff
2019-03-23T15:55:57 < Cracki> bridge meaning bridge wireless lan to wired lan, not "range extender"
2019-03-23T15:56:34 < bitmask> yea I'll have to see what kinda router settings there are
2019-03-23T15:56:57 < Cracki> a bridge can still do access control. or you have each wifi router actually do its own wireless LAN and route into wired LAN for uplink
2019-03-23T15:57:16 < bitmask> yea thats the fallback method
2019-03-23T15:57:23 < bitmask> if mesh costs more i'll just do that
2019-03-23T15:57:49 < bitmask> Id probably need a second router for downstairs so i'll probably forget about it
2019-03-23T15:57:58 < bitmask> its not my house so I'm not putting the money up
2019-03-23T16:08:36 < Cracki> if they need two routers to cover their territory, radio doesn't penetrate the walls/floors well, so they want wired backbone

2019-03-23T16:23:22 < jadew> haha, yeah

2019-03-23T17:07:48 < Cracki> it will as long as the french are under tyranny
2019-03-23T17:08:17 < mawk> yes jadew 
2019-03-23T17:08:20 < mawk> 19th week of protest
2019-03-23T17:08:22 < Cracki> for a movement with supposedly no clear goals, they do have impressive stamina
2019-03-23T17:08:35 < mawk> last week was very violent, so for the first time since Algeria war they sent the army today
2019-03-23T17:08:44 < Cracki> some know who the enemy is. I wonder when it'll break through general awareness.
2019-03-23T17:08:54 < mawk> but it's all for looks, the army has no right to intervene on national territory
2019-03-23T17:08:57 < mawk> it's just to scare protesters
2019-03-23T17:08:58 < jadew> they sent the army against the people?
2019-03-23T17:09:07 < jadew> ah
2019-03-23T17:09:17 < Cracki> army will shoot people, then people will assassinate politicians
2019-03-23T17:09:27 < mawk> I don't think the army is very okay with this
2019-03-23T17:09:32 < mawk> but anyway they can't do anything
2019-03-23T17:09:38 < Cracki> I'm sure they will do something
2019-03-23T17:10:00 < mawk> even during 2015 terror attacks the army was around the terrorist but couldn't shoot him or give their weapon to special forces that could have shot him
2019-03-23T17:10:04 < Cracki> "can't" is a word for just times.
2019-03-23T17:10:04 < mawk> the laws are very strict
2019-03-23T17:10:13 < mawk> the army can't do anything with their guns on national territory
2019-03-23T17:10:19 < jadew> in here, the socialist party's TV channel is all against the yellow vests
2019-03-23T17:10:31 < Cracki> shooting terrorists gives bad press. shooting "yellow vests" won't be mentioned in any press.
2019-03-23T17:10:32 < mawk> that's odd for a socialist tv
2019-03-23T17:10:45 < Cracki> the socialists are part of the problem
2019-03-23T17:10:47 < mawk> well police have gum bullet guns, and they use it at will
2019-03-23T17:10:56 < jadew> mawk, why is that?
2019-03-23T17:10:58 < mawk> something like 30 eyes have been shot and lost
2019-03-23T17:11:07 < mawk> because police doesn't shoot with real guns here
2019-03-23T17:11:10 < mawk> it's not america
2019-03-23T17:11:19 < jadew> no, I meant why did you think it's odd
2019-03-23T17:11:24 < mawk> well they have real guns, but if they use it they're instantly put into custody and there's an official investigation
2019-03-23T17:11:32 < Cracki> don't forget at least one band blown off by some grenade
2019-03-23T17:11:39 < Cracki> *hand
2019-03-23T17:11:41 < mawk> well socialism is all about what the people are protesting for jadew 
2019-03-23T17:11:47 < mawk> yeah Cracki there are the grenades too
2019-03-23T17:11:54 < jadew> mawk, against, I assume?
2019-03-23T17:11:55 < Cracki> yellow vests protest against things the socialists want
2019-03-23T17:12:05 < mawk> I mean true socialism jadew 
2019-03-23T17:12:08 < jadew> yeah, that's what I thought
2019-03-23T17:12:16 < mawk> but yeah they're protesting against the fake socialists that are in power
2019-03-23T17:12:17 < jadew> mawk, not sure what you mean
2019-03-23T17:12:17 < Cracki> socialism today anti-worker
2019-03-23T17:12:28 < jadew> oh... mawk those are not fake socialists
2019-03-23T17:12:31 < mawk> but at the very core it's a fiscal protest
2019-03-23T17:12:35 < Cracki> socialism has always been a bourgeois movement
2019-03-23T17:12:38 < mawk> they wanted to cancel a tax on fuel
2019-03-23T17:12:52 < mawk> and better redistribute wealth
2019-03-23T17:13:07 < jadew> right, it was because of that tax
2019-03-23T17:13:13 < jadew> for the record, tax = socialism
2019-03-23T17:13:18 < jadew> the more tax you have, the more socialism
2019-03-23T17:13:18 < Cracki> btw, I am sorry for starting this discussion
2019-03-23T17:13:41 < jadew> lowering taxes = more capitalism
2019-03-23T17:13:46 < jadew> increasing them = more socialism
2019-03-23T17:13:49 < mawk> yeah I mean the yellow vest would be very happy to have a more progressive income tax and increase the tax on upper levels of the income tax jadew 
2019-03-23T17:13:57 < jadew> now... about how you redistribute them, that's a different issue
2019-03-23T17:14:01 < mawk> it's just that it's injust in what it is currently
2019-03-23T17:14:06 < mawk> upper levels are low, low levels are high
2019-03-23T17:14:11 < mawk> in proportion to wealth
2019-03-23T17:14:19 < jadew> I don't agree to that tbh
2019-03-23T17:14:27 < jadew> I think everyone should pay the same
2019-03-23T17:14:33 < jadew> but that doesn't happen anywhere
2019-03-23T17:14:49 < jadew> why should someone pay more for the same services?
2019-03-23T17:15:06 < jadew> because the state makes no discrimination in the services it provides to the people, based on their income
2019-03-23T17:15:11 < Cracki> because they're willing to pay? that's capitalism
2019-03-23T17:15:12 < jadew> so why would you pay more for the same garbage
2019-03-23T17:15:25 < jadew> well, they're not willing, they're forced
2019-03-23T17:15:28 < mawk> in the ideal situation of no state debt yeah I agree jadew 
2019-03-23T17:15:34 < Cracki> capitalsocialism
2019-03-23T17:15:45 < jadew> they'd be willing to pay private parties for better services than what the state offers
2019-03-23T17:15:49 < Cracki> I think both systems are shit
2019-03-23T17:15:49 < mawk> or in the situation of being the USA and making whatever you want with financial rulings
2019-03-23T17:16:39 < Cracki> didnt the US sustain their government from nothing but import/export taxing maybe a few hundred years ago?
2019-03-23T17:16:55 < mawk> 10% of your wealth when you're poor isn't the same as 10% of your wealth when you're billionnaire, because common goods are the same price
2019-03-23T17:16:56 < Cracki> sure, smaller government then
2019-03-23T17:16:59 < mawk> they're not scaled according to your wealth
2019-03-23T17:17:11 < jadew> mawk, they don't have to scale
2019-03-23T17:17:20 < jadew> and that's why you want to get rich
2019-03-23T17:17:31 < jadew> so cheap shit remains cheap and you can buy it all
2019-03-23T17:18:05 < jadew> making it artificially scale, is just unfair
2019-03-23T17:18:13 < mawk> yeah
2019-03-23T17:18:27 < mawk> but currently the situation is that our debt equals our GDP
2019-03-23T17:18:36 < mawk> you have to take money, and that will be unfair
2019-03-23T17:18:46 < mawk> the fairest of that unfair situation would be to take money from those that can support it the most
2019-03-23T17:18:49 < mawk> since you have to take it anyway
2019-03-23T17:19:01 < mawk> you can't just go like Argentina by saying you won't repay anyone
2019-03-23T17:19:05 < mawk> when you go bankrupt
2019-03-23T17:19:24 < jadew> thing is, not those people made the problem
2019-03-23T17:19:32 < jadew> they actually made it less worse
2019-03-23T17:19:35 < mawk> yeah
2019-03-23T17:19:55 < jadew> so you're punishing the ones that alleviate the problem
2019-03-23T17:19:57 < mawk> well, that's one popular theory of macron, trickle down economics
2019-03-23T17:20:05 < jadew> while giving a free pass to those who make it and want to make it worse
2019-03-23T17:20:08 < mawk> but I'm not sure it's all that efficient for the upper levels
2019-03-23T17:20:09 < jadew> because they need shit
2019-03-23T17:20:37 < mawk> the poorest don't pay much, the richest don't pay much, the pressure is on the middle class currently
2019-03-23T17:20:43 < mawk> because the income tax isn't progressive enough
2019-03-23T17:21:10 < jadew> I think VAT + fixed tax on everyone should be sufficient
2019-03-23T17:21:17 < mawk> yeah that's one idea of macron
2019-03-23T17:21:34 < jadew> that's not a bad idea then
2019-03-23T17:21:38 < Cracki> do you guys think it'd be a good idea to stop the hemorrhaging by cutting money to a bunch of handout programs?
2019-03-23T17:21:49 < jadew> you spend more, you give more to the budget
2019-03-23T17:21:49 < mawk> not really
2019-03-23T17:21:59 < mawk> if you do the maths the welfare doesn't cost that much
2019-03-23T17:22:04 < mawk> less than 1 billion in france
2019-03-23T17:22:06 < Cracki> what does cost?
2019-03-23T17:22:07 < mawk> maybe 300 millions
2019-03-23T17:22:14 < mawk> tax fraud for instance
2019-03-23T17:22:17 < mawk> or tax niches
2019-03-23T17:22:22 < jadew> the problem with the handout programs is that you have to do it
2019-03-23T17:22:30 < jadew> otherwise you end up with desperate people
2019-03-23T17:22:42 < jadew> the solution is not to cut the handouts, but to find a solution so those people don't need them
2019-03-23T17:22:46 < jadew> (hire them)

2019-03-23T17:23:21 < Cracki> dunno :P where does the money go to?
2019-03-23T17:23:30 < Cracki> tax fraud isn't where it goes, it's where it doesn't come from

2019-03-23T17:23:34 < mawk> this kind of stats is illegal here so I don't know
2019-03-23T17:23:45 < mawk> but it goes to the poorest levels of population
2019-03-23T17:23:54 < Cracki> illegal numbers? hatefacts?
2019-03-23T17:23:55 < mawk> depending on the area it could be majoritarily immigrants I guess
2019-03-23T17:23:58 < mawk> yeah
2019-03-23T17:24:13 < mawk> but in rural areas it's not really the case, or northern areas of france
2019-03-23T17:24:14 < mawk> it depends
2019-03-23T17:24:22 < Cracki> forbidden knowledge
2019-03-23T17:24:29 < Cracki> I would think long and hard about that
2019-03-23T17:24:31 < mawk> but anyway it doesn't cost that much, it's maybe a problem to be tackled but it'd be one of the latest problems
2019-03-23T17:25:16 < Cracki> I don't know how france does it, but your neighbor germany is spending insane sums on imported welfare recipients
2019-03-23T17:25:28 < jadew> the handouts could be a lot smaller than they are now, for sure
2019-03-23T17:25:30 < jadew> at least in france
2019-03-23T17:25:35 < jadew> in here they are minimal
2019-03-23T17:25:39 < jadew> so people don't rely on them
2019-03-23T17:25:43 < mawk> yeah
2019-03-23T17:25:44 < Cracki> which, IF you wanted to drop welfare on them, could have been served cheaper in their home countries
2019-03-23T17:25:46 < jadew> they WANT to work
2019-03-23T17:25:54 < Cracki> single percentages want to
2019-03-23T17:25:55 < mawk> well it's minimal here too, it's like 1/3 of minimum salary
2019-03-23T17:26:04 < mawk> you can't really live on that unless you also have a subsidized appartment
2019-03-23T17:26:11 < mawk> and waiting list are 3 years long
2019-03-23T17:26:30 < mawk> so you have to do illegal stuff alongside it if you're in the right atmosphere like heated suburb areas
2019-03-23T17:26:34 < Cracki> it would be sensible to get work for those people you have, before importing more
2019-03-23T17:27:00 < Steffanx> For some people being unemployed is their job. :P
2019-03-23T17:27:05 < mawk> but macron is also trying to do that jadew lol

2019-03-23T17:27:15 < mawk> he's trying to get people on welfare to get a job
2019-03-23T17:27:22 < Cracki> the only effect (and intent) of importing from third world countries is to depress wages.
2019-03-23T17:27:24 < mawk> like if you refuse two jobs from the job agency in a row they cut the welfare money
2019-03-23T17:27:28 < Cracki> that helps nobody
2019-03-23T17:28:05 < Cracki> cut by how much?
2019-03-23T17:28:21 < mawk> by 100% for some months
2019-03-23T17:28:22 < Cracki> is there any incentive for people to seek work outside of france?
2019-03-23T17:28:32 < Cracki> such as... in their home countries?
2019-03-23T17:28:36 < mawk> I've never heard of that, no
2019-03-23T17:28:55 < Cracki> incentive also meaning pressure to not live on welfare
2019-03-23T17:29:03 < Cracki> or cutting welfare completely
2019-03-23T17:29:12 < mawk> that would provoke riots in suburbs
2019-03-23T17:29:22 < Cracki> he could send in his UN army then
2019-03-23T17:29:33 < Cracki> suburbs aren't french soil :>
2019-03-23T17:29:43 < mawk> if during a police chase a dumb kid dies on his scooter then it's riots during 5 days, hundreds of burned cars and injured police officers
2019-03-23T17:29:47 < mawk> so if they cut welfare it'd be a revolution
2019-03-23T17:30:06 < Cracki> this situation can't be resolved without violence and blood
2019-03-23T17:30:28 < Cracki> it'll only happen when the _alternative_ is more violence and bloodshed
2019-03-23T17:31:00 < Cracki> you can count on the elites wanting to stay unharmed, so that's where the yellow vests _should_ go
2019-03-23T17:31:16 < Cracki> rioting isn't very productive at all
2019-03-23T17:31:43 < mawk> yeah
2019-03-23T17:36:45 < jadew> mawk, sorry, but you said he wants to increase taxes
2019-03-23T17:36:53 < jadew> or already did?
2019-03-23T17:38:01 -!- R2COM [~R2COM@ip68-3-184-221.ph.ph.cox.net] has joined ##stm32
2019-03-23T17:38:56 < mawk> no I said he wanted to introduce a flat tax jadew 
2019-03-23T17:39:10 < mawk> so lower tax for higher wealth
2019-03-23T17:39:21 < mawk> but in the same time to fund """ecology""" he added taxes on fuel
2019-03-23T17:39:25 < mawk> and that's what sparked the protests
2019-03-23T17:40:19 < jadew> ah
2019-03-23T17:40:50 < jadew> then I'm not sure what the problem is
2019-03-23T17:40:53 < R2COM> i pay almost 50% tax on bonus pays to me
2019-03-23T17:40:58 < R2COM> its fucking ridiculous
2019-03-23T17:41:25 < mawk> also he removed "fortune tax" on immobiliary values
2019-03-23T17:41:31 < mawk> again helping the wealthiest
2019-03-23T17:41:39 < jadew> it just occurred to me earlier
2019-03-23T17:41:49 < jadew> if 100% tax is 100% socialism
2019-03-23T17:41:51 < R2COM> who removed that tax and where?
2019-03-23T17:41:58 < jadew> and 0% tax is 100% capitalism
2019-03-23T17:42:13 < jadew> then you can see where a country is on the spectrum, just by adding all the taxes together
2019-03-23T17:42:31 < R2COM> ah france
2019-03-23T17:42:32 < mawk> france was very close to 100% under Hollande lol
2019-03-23T17:42:46 < mawk> the highest level of income tax was something like 90%
2019-03-23T17:42:58 < mawk> but the supreme court ruled that it was confiscatory and unconstitutional
2019-03-23T17:43:16 < jadew> and I'm sure there's a study out there that tried to figure the right amount of each you need
2019-03-23T17:43:21 < R2COM> europe will turn into shit very soon
2019-03-23T17:43:37 < R2COM> all those war footages from middle east etc, in 30 years will be from europe
2019-03-23T17:43:44 < jadew> 90% tax is just insane
2019-03-23T17:43:50 < mawk> for the last level
2019-03-23T17:43:52 < mawk> but still
2019-03-23T17:43:52 < R2COM> jadew sweden is like that too
2019-03-23T17:44:06 < mawk> it's like 90% tax on whatever is above X million of personal income per year
2019-03-23T17:44:19 < mawk> but it was removed yeah
2019-03-23T17:44:19 < Cracki> jadew, 0% taxes would be anarchism because nothing maintains the state... you'd have a company that provides the services
2019-03-23T17:44:44 < mawk> you'd want to at least have taxes on regalian services
2019-03-23T17:44:47 < mawk> justice, army, police
2019-03-23T17:44:47 < jadew> Cracki, not necessarily
2019-03-23T17:44:54 < jadew> people could get together voluntarily
2019-03-23T17:45:01 < jadew> just for the sake of the community
2019-03-23T17:45:14 < mawk> sometimes you need national cooperation
2019-03-23T17:45:17 < mawk> for the army, for the law
2019-03-23T17:45:25 < jadew> (like they did for 10s of thousands of years)
2019-03-23T17:45:29 < R2COM> jadew how can people make and afford F16?
2019-03-23T17:45:34 < R2COM> there must be some tax
2019-03-23T17:45:54 < R2COM> in US, according to statistics around 30% from taxes go to military/defence
2019-03-23T17:45:55 < Cracki> I am SO sorry I started this discussion
2019-03-23T17:45:59 < mawk> lol Cracki 
2019-03-23T17:46:07 < R2COM> all the rest goes to support poor fucks and libs who dont work
2019-03-23T17:46:09 < Laurenceb_> https://imgur.com/WWakTzn
2019-03-23T17:46:10 < mawk> US has insane army spendings
2019-03-23T17:46:20 < R2COM> no it doesnt have insane army spending
2019-03-23T17:46:22 < jadew> R2COM, yeah, for that sort of stuff you need a bit of socialism, but not because people wouldn't be able to afford them
2019-03-23T17:46:26 < R2COM> its a myth with most imbeciles spread
2019-03-23T17:46:30 < R2COM> and dont know what exactly it is
2019-03-23T17:46:34 < jadew> but because someone has to build them and you don't want them to have all the power
2019-03-23T17:46:50 < mawk> maybe they're very needed R2COM 
2019-03-23T17:46:55 < mawk> but still it's higher than other countries
2019-03-23T17:47:07 < R2COM> i dont give fuck to other countries
2019-03-23T17:47:23 < R2COM> in US as i said % from taxes which go to military is 30%
2019-03-23T17:47:42 < R2COM> the rest goes to support poor fucks living in ghettos and support their useless children
2019-03-23T17:47:48 < Cracki> ^
2019-03-23T17:47:54 < R2COM> and medicals for immigrants
2019-03-23T17:48:12 < R2COM> and similar shit
2019-03-23T17:48:26 < Cracki> if you get that under control, murica rises to #1 ahead of hungary for my favorite destinations to bug out to
2019-03-23T17:48:28 < mawk> and addiction programs for the 99.9% american hooked up on opiates
2019-03-23T17:48:53 < R2COM> yes, so when i get a bonus check for $10k, in reality i get around $4.x k
2019-03-23T17:48:57 < R2COM> and that pisses me off
2019-03-23T17:49:00 < Cracki> and keep your 1A and especially 2A. that's rare.
2019-03-23T17:49:11 < mawk> what's A ?
2019-03-23T17:49:13 < Cracki> amendment
2019-03-23T17:49:16 < mawk> ah
2019-03-23T17:49:17 < mawk> right
2019-03-23T17:49:21 < Cracki> 1a is free speech, 2a is gun rights
2019-03-23T17:49:26 < mawk> yeah
2019-03-23T17:49:41 < mawk> free speech is so uncomprehensible here in europe, and especially france
2019-03-23T17:49:46 < Cracki> how about you let your company "pay" you the bonus in goods and services
2019-03-23T17:49:52 < mawk> we have laws against discussing slavery, holocaust, race, etc
2019-03-23T17:49:57 < mawk> you litteraly go to jail for it
2019-03-23T17:50:10 < mawk> you can't be a nazi supporter, etc
2019-03-23T17:50:17 < mawk> you can't show terror attack pictures
2019-03-23T17:50:24 < Cracki> there are speech codes on these things because if you question them, the truth might come out
2019-03-23T17:50:28 < mawk> you can't even mention terror attacks other than condemn it
2019-03-23T17:51:07 < Cracki> https://twitter.com/MGtheories/status/1107175360809132032
2019-03-23T17:51:16 < Cracki> you can simply _not_ comment
2019-03-23T17:51:18 < Cracki> that says a lot too
2019-03-23T17:51:19 < R2COM> i know there some laws in france like if you deny some genocide you go to real prison
2019-03-23T17:51:20 < R2COM> lol
2019-03-23T17:51:33 < con3> man that's insane
2019-03-23T17:51:37 < Cracki> nobody denies the holodomor or the great leap forward
2019-03-23T17:51:42 < R2COM> how the fuck can you go to prison for *saying* things
2019-03-23T17:51:45 < Cracki> or the south african genocide
2019-03-23T17:51:59 < Cracki> they read 1984 and used it as a manual
2019-03-23T17:52:03 < con3> well if you use a racial slur towards black people same happens in south africa
2019-03-23T17:52:13 < Cracki> you don't own your government
2019-03-23T17:52:18 < con3> vice versa doesn't apply
2019-03-23T17:52:21 < Cracki> that's the problem
2019-03-23T17:52:33 < mawk> yeah that's what I said R2COM 
2019-03-23T17:52:53 < mawk> it's the fabius-gayssot law from 1972
2019-03-23T17:53:04 < mawk> the first "memorial law" that banned any discussion on some historical events
2019-03-23T17:53:14 < Cracki> R2COM, murica is getting these laws too. in half the states you can't boycott a certain state, or question certain historical events.
2019-03-23T17:54:17 < Cracki> antigravity cat https://pbs.twimg.com/media/D2WMqXgU8AA_Kjf.jpg:orig

2019-03-23T17:56:18 < R2COM> ^
2019-03-23T17:56:21 < Cracki> so... can I have a story timy? yesterday there was this guy who wanted to do i2c with no tools at all. what macgyvering did you do in tricky situations where you had no proper tools?
2019-03-23T17:56:25 < R2COM> countries who punish for lolocaust denial
2019-03-23T17:56:37 < Cracki> shit, hungary is off the list
2019-03-23T17:57:14 < R2COM> seems like....its a Commie property!
2019-03-23T17:57:52 < R2COM> im disappointed to see Switzerland there
2019-03-23T17:58:10 < R2COM> its a cool country which tries to stay away from that euroshit
2019-03-23T17:58:15 < R2COM> and they still jumped on that boat
2019-03-23T17:58:22 < Cracki> can you guess why?
2019-03-23T17:58:26 < mawk> I have more stories about doing this with software than with hardware Cracki 
2019-03-23T17:58:33 < Cracki> I mean... swizzlerland... banks...
2019-03-23T17:58:39 < Cracki> stories!
2019-03-23T17:58:58 < Cracki> (all of history is stories, told and retold until you get a caricature)
2019-03-23T17:59:48 < Cracki> oh look denmark isn't on the map
2019-03-23T17:59:56 < Cracki> nor is NL :D
2019-03-23T18:00:17 < Cracki> crap, in the list
2019-03-23T18:00:26 < mawk> like writing a small container software in bash on a computer with no internet access to be able to properly boot an os
2019-03-23T18:00:33 < Cracki> yikes
2019-03-23T18:02:58 < con3> hmm... is there any example code for these ll drivers?
2019-03-23T18:03:09 < Cracki> we once had a lab assignment, basic microcontroller fuckery, but on a ratty board with shorts and loose connections. we were supposed to implement an IR/light receiver using ADC
2019-03-23T18:04:43 < Cracki> since they wouldn't let us touch the scopes, and they had no LAs. had to ferry the values out via serial to get a look. kinda obvious, but the assistants didn't suggest it and nobody else seemed to have the idea
2019-03-23T18:05:18 < Cracki> con3, they have a video for that? not sure if it actually delivers... https://www.youtube.com/watch?v=3dgwJFga674
2019-03-23T18:05:38 < con3> thanks Cracki!
2019-03-23T18:05:48 < con3> they seem to like HAL a lot more than ll
2019-03-23T18:05:50 < Cracki> you can skip the first minute at minimum
2019-03-23T18:06:12 < Cracki> at around 2:22 I see examples
2019-03-23T18:08:53 < con3> dammit
2019-03-23T18:09:31 < Laurenceb_> https://imgur.com/L8c9oyZ
2019-03-23T18:09:48 < mawk> lol
2019-03-23T18:10:11 < mawk> that forces a cast to Boolean Laurenceb_ 
2019-03-23T18:10:18 < mawk> it's maybe not ideal
2019-03-23T18:10:36 < mawk> also tab size too big, 4 is good
2019-03-23T18:10:42 < mawk> and should add a space after //
2019-03-23T18:10:52 < mawk> that sign is worth 5/20 for the effort
2019-03-23T18:11:44 < Laurenceb_> >remain using cancerscript as an argument
2019-03-23T18:11:52 < Laurenceb_> def want brexit now
2019-03-23T18:12:01 < Laurenceb_> internet cancer.js
2019-03-23T18:16:24 < Cracki> i see some "examples_ll" dirs in the stuff I have (F1 and F4) but only for some select nucleo boards
2019-03-23T18:17:24 < con3> Cracki: thanks, just realized it doesn't look like they have it for the F7, busy double checking. Only thing I can find is ll template
2019-03-23T18:17:58 < con3> eh they have it for one board
2019-03-23T18:18:06 < con3> maybe I should fetch my f4 
2019-03-23T18:18:49 < con3> guess HAL is the most supported for the time being
2019-03-23T18:20:05 < Cracki> are the examples easy enough to help you understand LL, then "port"?
2019-03-23T18:25:38 < con3> Cracki: I think I should be able to make sense of this, thanks for the help!
2019-03-23T18:25:57 < Cracki> np, I'm good at rubberducking
2019-03-23T18:26:08 < con3> Really wish someone would pop out a nice book on stm and embedded in general 
2019-03-23T18:26:35 < Cracki> I remember an "old" one on cm3
2019-03-23T18:26:46 < con3> my rubberducking has become abusive  this past while
2019-03-23T18:27:20 < kakimir> https://www.youtube.com/watch?v=olGTTzfxNiw chill saturday music
2019-03-23T18:28:36 < con3> Cracki: saw the one on cm3, was thinking more a mix of hal/ll and a good indepth explanation of the chipsets
2019-03-23T18:28:52 < con3> ref manuals are good though
2019-03-23T18:28:56 < Cracki> indeed that would be more useful than a gazillion pages on the damned core
2019-03-23T18:30:19 < con3> I've also grown some hate for cube the past while. It's nice for rapid prototyping, but if the generated code is broken in anyway you're f*cked. You have no idea what the generator is doing and spend so much time chugging through code trying to understand and fix it
2019-03-23T18:31:17 < R2COM> cube has some graphical glitches for me, it has some issues with GUI where things blink/overlap etc...not usable at this moment
2019-03-23T18:31:33 < mawk> yeah cube has some nasty bugs
2019-03-23T18:31:40 < R2COM> i deleted that shit
2019-03-23T18:31:46 < mawk> broken makefile on generate, generate just not working and you have to restart everything
2019-03-23T18:31:53 < mawk> clock solver that can't converge to a solution
2019-03-23T18:31:55 < con3> I spent so much time fixing fatfs that I feel I need therapy
2019-03-23T18:31:58 < R2COM> i have visualGDB with many various templates now its enough for me
2019-03-23T18:31:59 < mawk> lol
2019-03-23T18:32:13 < con3> It was such a dark time in my life
2019-03-23T18:32:25 < Cracki> last time I generated a blinky project with cube, it barfed impenetrable code at me. tons of comments for all kinds of special cases I don't care about, tons of stuff in the project directory, this ugly Capitalization naming scheme (Src, Inc, ...)...
2019-03-23T18:32:26 < con3> stupid pos
2019-03-23T18:32:28 < mawk> other than that cube is pretty nice when you're not an expert on writing all the boilerplate by yourself yet
2019-03-23T18:32:47 < mawk> it generates the bare minimum for system init Cracki 
2019-03-23T18:32:54 < mawk> if you don't forget to disable everything you don't need
2019-03-23T18:32:59 < mawk> like DMA SDIO whatever
2019-03-23T18:33:05 < Cracki> uh
2019-03-23T18:33:07 < mawk> enable the bare minimum, then it's good generated code
2019-03-23T18:33:12 < Cracki> it looked like I had to enable things, not disable things
2019-03-23T18:33:15 < con3> TBH I'd rather struggle my ass off and try and understand how to do this stuff myself than have cube do it
2019-03-23T18:33:21 < Cracki> ^
2019-03-23T18:33:27 < mawk> yeah in the earlier versions it was like that Cracki I think
2019-03-23T18:33:32 < mawk> but now it enables everything by default
2019-03-23T18:33:35 < Cracki> uh
2019-03-23T18:33:41 < Cracki> I downloaded that a few weeks ago
2019-03-23T18:33:45 < mawk> well not everything but it looks like it makes a selection of peripherals from your board and enables them
2019-03-23T18:33:48 < mawk> for whatever reason
2019-03-23T18:33:49 < con3> cube is great if you don't really want to learn in depth and get your hands dirty, but thats not what I want
2019-03-23T18:34:05 < mawk> it's just a boilerplate generator after all con3 
2019-03-23T18:34:07 < mawk> you still have to code
2019-03-23T18:34:11 < Cracki> and there wasn't anything to disable that I could see. it starts with configuring pins, peripherals, ...
2019-03-23T18:34:47 < mawk> yeah, I don't know about your exact board
2019-03-23T18:34:50 < mawk> the new UI is horrible
2019-03-23T18:34:56 < con3> mawk: I agree but the boilerplate setup is something that I think you should be able to do on your own :)
2019-03-23T18:34:56 < mawk> but there's a page that shows everything that is enabled
2019-03-23T18:34:57 < Cracki> let me try that again
2019-03-23T18:35:00 < mawk> in funny little layers
2019-03-23T18:35:11 < con3> also the new cube is really ugly or is it just me?
2019-03-23T18:35:13 < Cracki> no board, cubemx doesn't appear to know the bluepill or maple leaf mini
2019-03-23T18:35:29 < mawk> yeah for the bluepill you have to do it with the core itself
2019-03-23T18:35:41 < mawk> and set up SWD, LEDs, clocks yourself
2019-03-23T18:35:55 < Cracki> that POS asks me to download EVERYTHING again, all the fucking datasheets and whatnot
2019-03-23T18:35:58 < Cracki> every time I open it
2019-03-23T18:36:04 < Cracki> how fucking retarded are these people
2019-03-23T18:36:14 < con3> lol
2019-03-23T18:36:23 < con3> time to fight this multi master spi line again

2019-03-23T18:51:02 < Cracki> not actively. I've got a written exam on monday I have to study for, and I've run through setting a blinky up in cube before, and I didn't like what I saw.
2019-03-23T18:51:31 < Cracki> I'll probably walk through it outside of cube, see what's really needed and what cube just uses to obfuscate

2019-03-23T18:58:34 < con3> Cracki: Are you doing a degree part time?
2019-03-23T18:59:23 < Cracki> kinda, can't live without money, can't get money without working

2019-03-23T19:00:19 < Cracki> not so well
2019-03-23T19:00:27 < Cracki> because of other reasons
2019-03-23T19:01:40 < con3> sorry to hear, try to keep your head up and goodluck for monday. Life has a way of knocking us down
2019-03-23T19:01:43 < Cracki> it's been going on for too long. I'm sick of it by now. very few workplaces will need any of this higher course material
2019-03-23T19:02:26 < Cracki> depression is shit, but all the doctors can't help you unfuck the world.
2019-03-23T19:02:38 < Cracki> it's really not a sickness if the world is actually shit.
2019-03-23T19:03:18 < Cracki> i'm surrounded by brainwashed commies who gleefully support the destruction of society
2019-03-23T19:08:00 < con3> Cracki: doing a masters or something ? Higher course material?
2019-03-23T19:08:05 < Cracki> yes
2019-03-23T19:08:50 < con3> Cracki: Depression sucks, I've finally been able to manage mine but god do I not wish this on anyone
2019-03-23T19:09:01 < Cracki> it might have been smarter to take the bachelors and really start somewhere, but then I'd probably have given up on the master's completely.
2019-03-23T19:09:06 < con3> hmm.. I saw gatech released an online masters in cs
2019-03-23T19:09:41 < Cracki> my doc was a loser. he gave me the weakest shit, which did very little except it took a long while to get off it.
2019-03-23T19:09:48 < con3> what do you mean by take the bachelors and really start somewhere?
2019-03-23T19:10:12 < con3> Cracki: Mine gave me urbanol, ended up with major depression and an addiction to urbanol :D
2019-03-23T19:10:21 < Cracki> the therapist I managed to find was a woman, so that was totally useless. can't talk to 2019 women in this country about the problems of the world.
2019-03-23T19:10:42 < Cracki> what would help me is being around people that aren't fucking commies

2019-03-23T19:11:44 < Cracki> a friend's brother got beaten up recently. I think he's now the closest to understanding...
2019-03-23T19:11:58 < Cracki> his brother got beaten up by a dozen of the usual suspects.
2019-03-23T19:12:33 < con3> lol, a lot of the world is screwed, or it just looks like the mindset of everyone has really gone south. At times it feels like I'm living in some weird alternate dimension
2019-03-23T19:12:36 < Cracki> at uni, almost everyone is a hippie living in their imaginary utopia

2019-03-23T19:14:49 < con3> I would think so, but it's my normal if that makes sense? People just accept things here now. I'm at the point where I would like to push some positive change in this country. there's so much potential if it wasn't for a group of absolute pieces of shit
2019-03-23T19:16:36 < con3> I think we're also so divided at this point by these politicians pushing their own agenda.
2019-03-23T19:16:37 < con3> fuck them
2019-03-23T19:19:32 < Cracki> people are not in control of their governments anymore. that's bad. and they feel it now. that's even worse.
2019-03-23T19:20:43 < con3> I mean we're being hit with 7 and a half hours of loadshedding rn. People are still chanting and screaming to vote for the current national party
2019-03-23T19:22:15 < Cracki> that's an actual power outage. "shedding" would mean getting rid of load that is probably unnecessary. a dog doesn't shed every day, but once a year.
2019-03-23T19:22:27 < Cracki> I love these euphemisms introduced by the tyrants.
2019-03-23T19:22:34 < Cracki> such as "grooming gang" to speak of rape gangs

2019-03-23T21:41:13 < kakimir> nothing fancy
2019-03-23T21:42:35 < kakimir> but there is a trend to make fancy home saunas nowdays
2019-03-23T21:44:31 < kakimir> design stove, black walls, instead of bench there is something more like sunbathing chair type of structures, glass walls and door etc. starlight lighting to roof etc.
2019-03-23T21:45:55 < kakimir> imagination is the limit
2019-03-23T21:47:05 < kakimir> but yeah

If successful, the acceleration concept is projected to be both lower cost and use much less power, with the price of a single space launch reduced to under US$500,000.[2] The speed required to maintain Low Earth orbit is 27,000 kilometres per hour (17,000 mph).

2019-03-24T00:50:20 < jadew> doesn't work for me
2019-03-24T00:56:53 < jadew> doesn't seem to work in any browser
2019-03-24T00:57:17 < jadew> so it's either that you have something cached or they're blocking romanians
2019-03-24T00:57:44 < jadew> although, a look at the error log shows that it's just a bug
2019-03-24T01:00:03 < Cracki> aliex works here too. maybe it's your provider.

2019-03-24T02:11:47 < Cracki> some teachers you only learn to hate when you actually listen to what they say...
2019-03-24T02:13:01 < Cracki> this one seems to love repeating definitions, but does too few examples. and he loves to mention special cases by emphasizing what you do in the general case, and not emphasizing what you do in the special case.
2019-03-24T02:17:18 < jadew> good teachers are rare
2019-03-24T02:17:49 < jadew> I suppose if you pay $$$$$/yr, then you might get the best
2019-03-24T02:18:33 < Cracki> and the good teacher I know doesn't hold any lectures next semester, so if I fail this exam, this drags out one more semester. I've decided to start applying for jobs with the bachelor's I have and the almost finished master's
2019-03-24T02:19:10 < Cracki> this dude here has been holding the same lecture for over a decade at least. nothing really changes.
2019-03-24T02:19:31 < Cracki> people complain sufficiently little, which needn't be an indication of quality, but merely of being dumbfounded
2019-03-24T02:27:05 < Cracki> he's doing a circularity check algorithm, where if you have alpha = func(beta), so the graph contains (beta,alpha) edges, and you chase *down* the edges, but he keeps saying "alpha depends on beta" which makes you think *up* the edges and it's driving me nuts
2019-03-24T02:28:07 < Cracki> the example is so goddamn easy to understand, if he just stopped talking and merely pointed at things
2019-03-24T02:32:54 < Cracki> fuck it, I'll just ask him to test me on a lecture he gave last year. this is insane.

2019-03-24T04:01:47 < jadew> every word helps

2019-03-24T04:21:48 < R2COM> hm i dont see that setting in any of those properties
2019-03-24T04:22:53 < jadew> sounds like a -D directive
2019-03-24T04:32:00 < con3> this might be a stupid question, but why would you use the wwdg. It looks like it's used when processes refresh the timer too quickly I can't think of a reason why that would happen?
2019-03-24T04:33:25 < jadew> con3, outside sensor triggers too early
2019-03-24T04:33:30 < jadew> could mean malfunctioning hardware
2019-03-24T04:34:20 < jadew> too early is just as bad as too late
2019-03-24T04:34:22 < jadew> ask any woman
2019-03-24T04:34:39 < con3> ^lol
2019-03-24T04:34:50 < con3> what do you mean by outside sensor triggers too early?
2019-03-24T04:35:06 < jadew> for example if you're expecting a response from an outside sensor
2019-03-24T04:35:53 < jadew> and you know that event can't happen below a specific time period
2019-03-24T04:36:33 < con3> hmm
2019-03-24T04:38:00 < con3> the external sensors I use are coupled by spi or some other peripheral so the results are returned in a very set way. Do you mean something where you say trigger something then wait for the response and then if the response happens immediately you know it's faulty cause it should've taken longer for the event to happen?
2019-03-24T04:38:30 < jadew> consider something that controls a drill bit
2019-03-24T04:38:34  * con3 realizes its 5 am
2019-03-24T04:38:48 < jadew> and you know it can't spin faster than say 100 RPM
2019-03-24T04:39:31 < jadew> if you start getting interrupts every millisecond, you might want to stop doing whatever it's doing
2019-03-24T04:40:07 < con3> jadew: I think I understand what you mean. I thought of it as internal to the device. For me the wdg was something that would ensure the mcu doesn't get stuck in some infinite loop or polling forever
2019-03-24T04:40:42 < jadew> yeah, I'm sure there are internal scenarios where that can be used
2019-03-24T04:40:52 < jadew> but they're probably fewer
2019-03-24T04:41:20 < con3> thanks for the help jadew, really appreciate it
2019-03-24T04:41:25 < jadew> np
2019-03-24T04:41:34 < con3> now I need to figure out how to set those windows
2019-03-24T04:41:40 < jadew> I'm off to bed, I want to drill stuff in the morning
2019-03-24T04:41:46  * con3 heads off to figure stuff out

2019-03-24T13:04:49 < jpa-> DisruptiveNL: is this still about the usb host side of things?
2019-03-24T13:06:02 < DisruptiveNL> jpa: yes I am further now and first implemented the datasheet
2019-03-24T13:06:22 < DisruptiveNL> jpa: I have tested the hardware with MBED and that worked (also USB OTG)
2019-03-24T13:06:36 < karlp> since when did mbed have function usb?
2019-03-24T13:06:55 < DisruptiveNL> since recent I think? It has a library for it
2019-03-24T13:07:47 < karlp> they've never mentioned it in their news, and there's an old usb lib in user contrib for old mbed.
2019-03-24T13:07:51 < karlp> got a link?
2019-03-24T13:15:38 < DisruptiveNL> i am searching wait
2019-03-24T13:16:02 < DisruptiveNL> https://os.mbed.com/handbook/USBHost
2019-03-24T13:16:39 < DisruptiveNL> its in Beta! but I have tried it and worked on my B-l475e-iot board so I knew my board and hardware were ok!

2019-03-24T14:21:34 < karlp> not really, I just spent a while trying to work out why it was nmot there
2019-03-24T14:21:46 < karlp> I wanted to use it as another reference platform to compare against cube/hal and locm3
2019-03-24T14:21:52 < Steffanx> ah
2019-03-24T14:21:59 < karlp> and was like, "uh, what? you're just ignoring this major periph?!"
2019-03-24T14:24:50 < Steffanx> Did you ask them and get an answer to that or ..?
2019-03-24T14:30:05 < karlp> no, decided they simply had no resoruces assigned to it, and I was interested in doing it for them in anyway, so gave up
2019-03-24T14:30:11 < karlp> was curious to hear if it had really changed.
2019-03-24T14:30:37 < karlp> mbed was somewhat attractive because it has seirous dev resources behind it, but if it's nto doing anything I nwant..... :)

2019-03-24T20:37:42 < Cracki> anyone who says "sq/m" for square meters can't be trusted to handle numbers
2019-03-24T20:39:41 < kakimir> indeed
2019-03-24T20:44:24 < mawk> lol
2019-03-24T20:44:26 < mawk> sq/m
2019-03-24T20:46:08 < mawk> their computations seem right tho Cracki 
2019-03-24T20:46:21 < mawk> it's nothing real advanced
2019-03-24T20:46:35 < mawk> but maybe they didn't show every place people went to
2019-03-24T20:46:39 < Cracki> they show aerial pictures of empty streets
2019-03-24T20:46:40 < mawk> or they removed people from the count
2019-03-24T20:46:45 < Cracki> I'd like to see actual crowd shots
2019-03-24T20:47:03 < Steffanx> shots in the crowd you mean?
2019-03-24T20:47:04 < Cracki> and then, they can claim counts for a specific point in time
2019-03-24T20:47:05 < mawk> even at the max crowd density I don't think you can add up to 700k
2019-03-24T20:47:17 < mawk> let me try to do it
2019-03-24T20:47:25 < Cracki> still, it MUST be illegal to question the official number!!

2019-03-24T20:47:36 < Cracki> ah, finally
2019-03-24T20:48:00 < Cracki> i really don't care about the numbers, but the methodology leaves something to be desired
2019-03-24T20:48:20 < Cracki> I accept their number = density * area approach, but not how they select the basis of their measurements

2019-03-24T20:49:32 < Cracki> the assumed densities sound plausible and I think at the bottom there's a source for these numbers
2019-03-24T20:49:49 < Cracki> areas... hm well they could have shown pictures of the actual crowds
2019-03-24T20:50:14 < mawk> yeah
2019-03-24T20:50:18 < mawk> to check the real densities
2019-03-24T20:50:32 < mawk> but even at max density of 4 people per m³ you don't even get 200k

2019-03-24T23:05:29 < Cracki> grml lecturer does 15 minutes recap every lesson. I could edit the lecture down to 20% of its time. then 2-3x time compression, turns 25 hours into 2 hours
2019-03-24T23:08:15 < qyx> how much does it cost?
2019-03-24T23:13:06 < Cracki> public uni, so half their time is paid for research anyway
2019-03-24T23:13:32 < Cracki> I think he could hold more effective lectures if he would lead with the example and then formalize
2019-03-24T23:14:18 < Cracki> wasting 5-10 minutes on def, which is nice but gives no intuition
2019-03-24T23:16:58 < Cracki> core ideas and exam consist of half a dozen algorithms against particular data structures. nothing all that complicated. BUT he has to dress it up in formalism before revealing it

2019-03-25T13:07:56 < jadew> any ideas on how to drill bigger holes accurately into aluminium sheets?
2019-03-25T13:08:16 < jadew> mine seem to come up square, really off, or both
2019-03-25T13:09:34 < jadew> all the small holes were fine
2019-03-25T13:09:50 < jadew> except for one, where I drilled through the vise
2019-03-25T13:09:51 < zyp> how big are we talking?
2019-03-25T13:10:02 < jadew> 3 mm small ones, 8 mm bigger ones
2019-03-25T13:10:10 < zyp> are you using a drill press?
2019-03-25T13:10:14 < jadew> yeah
2019-03-25T13:10:42 < jadew> tried it on wood and the holes came up right
2019-03-25T13:10:59 < jadew> in aluminium sheets they seem to be better if I increase the speed
2019-03-25T13:11:06 < jadew> but I'm not sure if that's what I should do
2019-03-25T13:11:59 < zyp> do you have anything behind the sheet?
2019-03-25T13:12:00 < jadew> tried with pilot holes too and the same thing happened
2019-03-25T13:12:05 < jadew> no
2019-03-25T13:12:07 < jadew> should I?
2019-03-25T13:12:12 < zyp> put a piece of wood behind
2019-03-25T13:12:29 < jadew> I'll give it a try
2019-03-25T13:12:30 < zyp> should keep it from deforming
2019-03-25T13:12:37 < jadew> I guess I'll have to clamp it differently then
2019-03-25T13:12:53 < srk> cutting fluid and low rpm maybe
2019-03-25T13:13:11 < jadew> I used low RPM, but I think that was part of the problem
2019-03-25T13:13:34 < jadew> being so soft, I think the drill cuts too much into it and pulls it
2019-03-25T13:13:42 < jadew> I don't know how much run out I have in the drill bit
2019-03-25T13:14:03 < jadew> but maybe it bends the drill a bit because it bites so much?
2019-03-25T13:14:14 < jadew> the chips are long and big
2019-03-25T13:14:20 < jadew> thick
2019-03-25T13:16:19 < jadew> I'm sure that if I drilled this by hand, it would have looked much better
2019-03-25T13:17:52 < jadew> I guess I need new front panels now
2019-03-25T13:18:22 < qyx> how thick is the sheet?
2019-03-25T13:18:34 < jadew> about 2 mm

2019-03-25T13:19:29 < qyx> works great with plastic and alu

2019-03-25T13:20:35 < qyx> yeah
2019-03-25T13:22:41 < karlp> that's just a step bit, it won't fix drills not drilling though.
2019-03-25T13:23:55 < zyp> step bits are awesome but it won't keep your sheet from deforming
2019-03-25T13:24:53 < qyx> idk my 1.5mm front panels are not deformed with them
2019-03-25T13:25:28 < qyx> also it is probably a different story with eg. AlMg3 vs. pure alu
2019-03-25T13:25:35 < jadew> what speed are you drilling them with?
2019-03-25T13:26:17 < jadew> also, do you use a center punch? (I did)
2019-03-25T13:26:47 < zyp> https://bin.jvnv.net/file/vIHR7.jpg <- I used a step bit for drilling the holes for the conduits in my rack cabinet
2019-03-25T13:27:12 < qyx> jadew: usually I just use an accu screwdriver (~1400rpm)
2019-03-25T13:27:24 < jadew> I see
2019-03-25T13:27:47 < zyp> even though it's a steel panel, it's enough to deform it
2019-03-25T13:28:03 < zyp> not enough to matter, of course, but still
2019-03-25T13:28:20 < qyx> zeah but that steel is probably 0.6mm or so
2019-03-25T13:28:41 < zyp> yes
2019-03-25T13:30:58 < zyp> 1.52mm apparently

2019-03-25T21:53:58 < cjbaird> Must print up some QSL cards with Blackletter Gothic and that...
2019-03-25T21:54:50 < cjbaird> Tried using it as an antenna too-- best match was on the 80m band..
2019-03-25T22:00:49 < cjbaird>  /Maybe/ got some Nucleo32 boards arriving today.. (the F303, which isn't totally busted wrt arduino-compatibilty)
2019-03-25T22:01:48 < mawk> what do you mean by arduino compatibility ? you want the arduino ide on it ?
2019-03-25T22:01:57 < mawk> or you mean the existing hardware like « shields »
2019-03-25T22:02:41 < cjbaird> The F4xx '32s have things like the 'A4/A5' pins hardwired as inputs, which gets in the way of how Arduino Nano shields use that for SPI.
2019-03-25T22:03:36 < cjbaird> The F421 I got even has a few of the An pins not even connected up to the CPU.
2019-03-25T22:04:16 < cjbaird> Well that was a waste of my hard-bludged pensioner bux.
2019-03-25T22:14:33 < cjbaird> Currently helping a local mate get up to speed with developing on stm32.. He's getting a few "2 gram" HAB trackers made up (FeatherHAB).

2019-03-26T03:51:36 < Guest9692> Hey I was wondering if someone could look over some code I wrote, it is really basic and I have no clue why it is not working
2019-03-26T03:51:43 < Guest9692> I am just trying to send a single byte over UART
2019-03-26T03:51:46 < Guest9692> https://pastebin.com/kKB8DzxD
2019-03-26T03:52:11 < Guest9692> I am using a ST-Nucleo-F030R8 as my dev board
2019-03-26T03:52:18 < Ultrasauce> a minimal example, unprompted? wtf
2019-03-26T03:53:18 < Guest9692> Is posting something like this not allowed? If it isn't my bad and I will just ask some friends tomorrow that know more about this kind of stuff
2019-03-26T03:53:53 < Ultrasauce> er sorry sarcasm, that was a compliment
2019-03-26T03:54:05 < Guest9692> no worries, it just is hard to tell over text sometimes :)
2019-03-26T03:54:24 < Guest9692> I thought it probably was a good thing, meaning most people post their entire code base and its impossible to debug lol, but I was just making sure
2019-03-26T03:55:29 < kakimir> interesting multiplications in there
2019-03-26T03:57:28 < kakimir> I have not seen such a trick before
2019-03-26T03:57:29 < Ultrasauce> exactly what happens when your main() returns depends on a couple details of your linker/startup code but it is probably not a thing you want
2019-03-26T03:57:44 < kakimir> I was thinking the same
2019-03-26T03:58:23 < kakimir> if undesirable things happen when main returns it has not yet clocked out the data
2019-03-26T04:00:33 < Guest9692> The reason for the multiplication for the register width is because I use a macro for all my pin initialization
2019-03-26T04:01:01 < Guest9692> I was sick of typing them out, so I wrote a python script that takes a spreadsheet with my pin names, descriptions, and intended direction and stuff and outputs a setup file
2019-03-26T04:01:04 < Guest9692> it looks something like this
2019-03-26T04:01:05 < Guest9692> https://pastebin.com/hdezcQWA
2019-03-26T04:01:43 < Guest9692> And so some of the registers you need to set are different widths, so I just used some multiplication to make the macro work for all cases
2019-03-26T04:01:44 < Guest9692> but anyways
2019-03-26T04:01:51 < Guest9692> what do you mean it depends on my linker/startup code?
2019-03-26T04:01:56 < Guest9692> how would I figure out what is going on?
2019-03-26T04:02:13 < Ultrasauce> the short answer is just put while(1); before the return and see if it works
2019-03-26T04:02:15 < englishman> main is never supposed to return
2019-03-26T04:03:39 < Guest9692> I assumed the compiler would turn a return like that into an infinite loop but wasnt sure
2019-03-26T04:03:43 < Guest9692> just tested, still not working
2019-03-26T04:03:49 < Guest9692> (added a while(1))
2019-03-26T04:04:18 < kakimir> well there usually is while(1) after main() call in startup code
2019-03-26T04:04:39 < kakimir> or same in asm or so
2019-03-26T04:04:57 < kakimir> but when you return from main all bets are off

2019-03-26T04:17:09 < englishman> i know where you can get one real cheap
2019-03-26T04:17:35 < Ultrasauce> not yet but we did move into a real space that could perhaps house one

2019-03-26T04:56:09 < Guest9692> also Ultrasauce, your company sounds like it is doing some badass stuff I am envious of the product you guys are designing it sounds incredible if you can actually get it working 100%
2019-03-26T04:56:45 < Guest9692> fun fact since youre in the camera space, idk if you heard but the guy who invented the CMOS sensor has come forward claiming he has a sensor now that doesnt need crazy cooling and works at room temperature that has 1 photon resolution on the sensor
2019-03-26T04:56:58 < Guest9692> which is mind blowing
2019-03-26T04:57:54 < englishman> actually there are some retail cmos sensors with 0.7 e- total dark noise
2019-03-26T04:58:26 < englishman> but imo the real progress has been in dynamic range
2019-03-26T04:58:48 < englishman> using some crazy ass tricks and 7 transistors per photodiode now
2019-03-26T04:59:03 < englishman> to get 100+dB dynamic range
2019-03-26T04:59:24 < englishman> even on global shutter sensors
2019-03-26T05:00:32 < Guest9692> Last year in high school I did a research project on dynamic range for self driving cars, by varying exposure/shutter speed on three cameras and combining their inputs through an FPGA (or GPU, but we only got 30fps on that) you can reach a dynamic range of like 150+
2019-03-26T05:01:07 < Guest9692> I think the cost of our unit was under $1000 using off the shelf components
2019-03-26T05:01:11 < Guest9692> it was a little big though
2019-03-26T05:01:18 < machinehum> Stoked for my apple card
2019-03-26T05:01:34 < machinehum> I'm really excited for a completely normal card
2019-03-26T05:01:36 < englishman> nice try canuck
2019-03-26T05:03:04 < englishman> pretty cool project for highschool
2019-03-26T05:04:31 < Guest9692> thank you :)
2019-03-26T05:05:24 < Guest9692> I am lucky to live in a town with a good engineering school nearby so I had access to some labs that gave me some $$$ to test with, I think they ended up using it on their car design? not sure what happened in the end
2019-03-26T05:06:04 < Guest9692> but wait so youre saying with only 7 transistors / photodiode you can get 100+ dB on global shutters?
2019-03-26T05:06:12 < Guest9692> can you link me something about this? I would love to read more

2019-03-26T10:29:35 < Thorn> has anyone used https://satechi.net/products/aluminum-bluetooth-wireless-keyboard ? I can't find any reviews
2019-03-26T10:43:00 < dongs> you can't afford that
2019-03-26T10:48:39 < Thorn> $65 here https://technopoint.ru/product/9aa41fbaf8633332/klaviatura-satechi-st-ambks-ru-sale/
2019-03-26T10:49:13 < dongs> why would you want that anyway
2019-03-26T10:49:21 < dongs> just looks like a typical overpriced hipster keyboard
2019-03-26T10:49:27 < dongs> and who the fuck is satechi
2019-03-26T10:49:32 < dongs> some chinatrash brand?
2019-03-26T10:51:03 < Thorn> never heard the name before
2019-03-26T10:51:21 < dongs> they make mostly hipster shit
2019-03-26T10:51:25 < dongs> rebranded china stuff
2019-03-26T10:51:27 < dongs> macbook docs etc
2019-03-26T10:51:33 < Thorn> it seems to be a clone of the apple keyboard but quite a bit cheaper

2019-03-26T13:09:46 < kakimir> hmm found 0805 size anti-surge resistors that can do pretty high pulse loads
2019-03-26T13:10:16 < kakimir> in sub-millisecond range >100W
2019-03-26T13:10:29 < kakimir> I don't know if I'm seeing straight
2019-03-26T13:11:33 < srk> oO
2019-03-26T13:14:30 < kakimir> and cheap too
2019-03-26T13:15:42 < kakimir> I'm fine with 100W
2019-03-26T13:19:23 < kakimir> undo F9
2019-03-26T13:19:27 < kakimir> - ltspice
2019-03-26T13:22:20 < kakimir> but anyway with these resistors I don't need to sweat about adding some direct clamps to line
2019-03-26T13:23:23 < kakimir> to clamp the voltage to say to 100-150V before the actual protection
2019-03-26T13:23:32 < Thorn> what is >anti-surge resistors
2019-03-26T13:23:45 < Thorn> varistors?
2019-03-26T13:24:19 < kakimir> it's the chad of resistors
2019-03-26T13:25:09 < kakimir> can take thunderbolts any day

2019-03-26T13:28:18 < kakimir> interesting - inputs need clamping of 1mA total
2019-03-26T13:28:25 < kakimir> @ 300V
2019-03-26T13:28:46 < kakimir> basically I don't need to care
2019-03-26T13:30:39 < kakimir> even with 0mA load
2019-03-26T13:31:00 < kakimir> it takes forever to reach critical voltages with the capacitance

2019-03-26T16:47:28 < Ecco> Hi :)
2019-03-26T16:47:34 < Ecco> I'm running into the weirdest bug
2019-03-26T16:47:52 < Ecco> STM32 F7 executing code from a QSPI external flash
2019-03-26T16:48:01 < Ecco> Using the built-in memory-mapped mode
2019-03-26T16:48:41 < Ecco> At some point during execution (takes a while, like a minute or so), the CPU hangs
2019-03-26T16:48:54 < Ecco> if using the debugger, every memory address reads zero
2019-03-26T16:49:05 < Ecco> - disabling L1 ICache prevents the bug from happening
2019-03-26T16:49:50 < Ecco> - lowering the Flash freq to 48 MHz down from 96 Mhz too
2019-03-26T16:50:18 < Ecco> - stepping with GDB around the "bug" makes it disappear
2019-03-26T16:50:24 < Ecco> but as soon as we hit "continue", it hangs again
2019-03-26T16:50:36 < Ecco> Would you guys have any idea what could be going on?

2019-03-26T17:01:17 < emeb_mac> I have seen some very odd F7 behavior when clock / power settings aren't correct though - might double check that

2019-03-26T18:45:50 < englishman> yee
2019-03-26T18:46:04 < englishman> stm32 is so far behind it isn't funny
2019-03-26T18:46:09 < Laurenceb> the ram is onboard O_o
2019-03-26T18:46:17 < BrainDamage> there's a good chane that all future 'micros' will be riscv
2019-03-26T18:46:25 < BrainDamage> esp with the free ip
2019-03-26T18:46:46 < englishman> good thing the Japs bought arm for $25b
2019-03-26T18:46:48 < Laurenceb> woah the KPU looks actually decent too
2019-03-26T18:49:11 < Laurenceb> looks like it can do 6*6 pixel kernel at 800MHz O_o
2019-03-26T18:49:58 < Laurenceb> so their 60fps@VGA would actually be with decent high end neural network shit
2019-03-26T18:50:25 < Laurenceb> this is going to btfo even raspberry pi
2019-03-26T18:53:31 < Laurenceb> it just missing decent analogue shit
2019-03-26T18:54:43 < englishman> who cares
2019-03-26T18:54:49 < englishman> it has spi for sensors

2019-03-26T18:56:50 < Steffann> Is this your new esp32 mr englishman ?
2019-03-26T18:57:07 < Laurenceb> unlike esp32 it is actually good

2019-03-26T19:31:22 < Cracki> yes
2019-03-26T19:31:48 < Cracki> and 1000 can work in both polarities (differential), iirc
2019-03-26T19:31:54 < aandrew> auto-mdix will not, however handle all 16 variations. in 10/100 it will ONLY swap pair A and B, and in 1000 it will do a particular swap only (don't know it offhand)

2019-03-26T19:32:09 < aandrew> well the differential pair inversion is built in to even the cheapest 10/100 PHYs
2019-03-26T19:32:14 < aandrew> it's a non-issue
2019-03-26T19:32:17 < Cracki> <- nonpro
2019-03-26T19:32:40 < aandrew> I had a schematic error where I had pair A going to RJ45 1-2 and B going to 7-8, not 3-6
2019-03-26T19:32:56 < aandrew> so the symptom was the switch linking up just fine, but the PHY saying no link
2019-03-26T19:32:59 < Cracki> you could even have 8!=40320 permutations
2019-03-26T19:33:05 < Cracki> if you want a fucked cable
2019-03-26T19:33:17 < aandrew> and no gigabit operation at all, and no autoneg at 10/100
2019-03-26T19:33:37 < Cracki> so what then, board surgery or new board
2019-03-26T19:33:38 < aandrew> once I put 1-2 and 3-6 on PHY pair A&B it came up immediately
2019-03-26T19:33:53 < aandrew> nah it will be new board for second prototype (there are lot of other issues)
2019-03-26T19:34:04 < aandrew> but for now it's a pair of RJ45 punchdowns with the wiring corrected
2019-03-26T19:34:11 < Cracki> ah right
2019-03-26T19:34:18 < aandrew> so normal cable -> [unfucker block] --> normal cable
2019-03-26T19:34:32 < aandrew> yeah I was thinking of cutting traces but then came to my senses

2019-03-26T19:45:34 < zyp> not much in the way of connectivity, just uart, spi and i2c

2019-03-26T19:47:21 < zyp> probably useful for doing some neural net computer vision stuff and digesting it into data simple enough to output over a uart or similar
2019-03-26T19:47:45 < zyp> but not so much else, I guess

2019-03-26T22:37:39 < karlp> VERBOSE and V= are not part of make itself.
2019-03-26T22:37:45 < karlp> they're things implemented in peoples makefiles.
2019-03-26T22:38:37 < Guest9692> karlp: Thank you good to know
2019-03-26T22:38:49 < Guest9692> and Rickta59: Thank you for helping me figure out I was a dummy lol
2019-03-26T22:39:19 < Guest9692> for the linker I can just "-T /path/to/my_file.ld" and that should work, right?
2019-03-26T22:39:36 < Guest9692> to my gcc flags ^^
2019-03-26T22:39:52 < karlp> man, using cmake and just setting piles of flags like that seems like just pain for no gain.
2019-03-26T22:40:35 < karlp> do you really intend to have crt0 stuff linked in as well? (you probably don't)
2019-03-26T22:41:11 < Guest9692> I am sorry I never was really taught about linkers or make, this is my first time really going through this kind of stuff
2019-03-26T22:41:21 < karlp> ok, so...
2019-03-26T22:41:41 < karlp> you didn't like platformio, but you went and tried to build cmake cross compile build scripts from scratch?
2019-03-26T22:41:53 < Guest9692> yeah, gotta learn sometime right?
2019-03-26T22:42:04 < karlp> that's like "I don't like VW, so I started learning how to refine petrol"
2019-03-26T22:42:36 < karlp> separate what you _want_ to learn from what you donð't.
2019-03-26T22:42:55 < karlp> do you want to spend time learning how cmake works, or do you want to spend time learning how your target works, and developing your target applications?
2019-03-26T22:43:18 < Guest9692> definitely the latter
2019-03-26T22:43:40 < karlp> so.. back to platformio?  or prebuilt cmake or prebuilt make or prebuilt something from someone else, 
2019-03-26T22:43:49 < karlp> what led you to choose building your own cmake?
2019-03-26T22:44:17 < Guest9692> I was trying to use Unity to do unit tests with platformio, but it was being weird about what could go in each folder
2019-03-26T22:44:31 < Guest9692> and also the thought I might want to generate different binaries for different tests
2019-03-26T22:44:46 < Guest9692> so I wanted to be able to compile everything myself

2019-03-27T00:33:42 < Laurenceb_> dunno but there is a pepe at the top
2019-03-27T00:34:40 < AaronFiz> " Article 13 holds larger technology companies responsible for material posted without a copyright licence. Tech companies already remove music and videos which are copyrighted, but under the new laws they will be more liable for any copyrighted content. "
2019-03-27T00:35:22 < AaronFiz> "Critics claimed Article 13 would have made it nearly impossible to upload even the tiniest part of a copyrighted work to Facebook, YouTube, or any other site.However, specific tweaks to the law made earlier this year made memes safe "for purposes of quotation, criticism, review, caricature, parody and pastiche". "
2019-03-27T00:35:27 < mawk> it's not even larger companies
2019-03-27T00:35:35 < mawk> if you're a small company with 3+ years of existence, you fall under the article
2019-03-27T00:35:38 < mawk> 3 or 5, can't remember
2019-03-27T00:36:06 < Laurenceb_> somehow I think Joshua Moon will just send them another troll email if they complain to him

2019-03-27T13:13:33 < zyp> didn't work so well, 1.6mm is too thin to be a good fit :)
2019-03-27T13:17:58 < zyp> https://git.jvnv.net/git/altium_lib.git <- footprint might be in here, but I'm not sure

2019-03-27T13:24:37 < aandrew> awesomely expensive, and useless for debugging? yes
2019-03-27T13:27:38 < zyp> I don't think it's expensive at all, I'm looking at <$0.1 per board
2019-03-27T13:28:37 < zyp> and the clip works fine when you need to leave it connected for debugging

2019-03-27T14:40:34 < dongs> lol
2019-03-27T14:40:35 < dongs> awful
2019-03-27T14:45:44 < zyp> nice
2019-03-27T14:46:17 < dongs> what is mdio when talking about ethernet?
2019-03-27T14:46:22 < dongs> is that same as RMII shit?
2019-03-27T14:46:24 < zyp> phy management
2019-03-27T14:46:40 < dongs> hmm
2019-03-27T14:46:52 < dongs> is RTL8211E a phy?
2019-03-27T14:47:15 < zyp> yes
2019-03-27T14:48:20 < dongs> hmm this is interesting as fuck
2019-03-27T14:48:29 < zyp> *MII is the signals that carry the ethernet packets for each direction
2019-03-27T14:48:32 < dongs> this japtv demod can *directly* connect to such phy
2019-03-27T14:48:48 < dongs> rf > ethernet
2019-03-27T14:48:54 < zyp> MDIO is an out of band management bus that the MAC uses to configure and monitor the PHY
2019-03-27T14:49:12 < zyp> two lines, kinda like i2c, except not i2c
2019-03-27T14:49:38 < dongs> and the parallel-ish bus is the TXDxx + TXCLK + TXCTL?
2019-03-27T14:49:44 < dongs> for actual data to send
2019-03-27T14:49:45 < kakimir> kaki hello
2019-03-27T14:49:56 < zyp> yeah, that's RMII or similar
2019-03-27T14:50:01 < dongs> ah hm and RXD isnt connected
2019-03-27T14:50:05 < dongs> so this is just dumb pumping shit out
2019-03-27T14:50:09 < dongs> probly not even IP?
2019-03-27T14:50:18 < dongs> it only has tx* connected
2019-03-27T14:50:21 < dongs> and rx* stuff is pulled up
2019-03-27T14:50:42 < zyp> haha, cool
2019-03-27T14:50:47 < dongs> can you output IP without receive?
2019-03-27T14:50:53 < dongs> some kinda udp/multicast shit?
2019-03-27T14:50:55 < zyp> but yeah, the rx half and tx half is independent
2019-03-27T14:51:15 < zyp> well, kinda
2019-03-27T14:51:17 < kakimir> can we expect negedge mean falling edge?
2019-03-27T14:51:30 < dongs> dongsedge
2019-03-27T14:52:43 < zyp> unidirectional udp over multicast in theory is possible
2019-03-27T14:52:58 < dongs> what would this output if it wasnt that
2019-03-27T14:53:02 < dongs> if only tx is connected
2019-03-27T14:53:06 < dongs> not even ethernet?
2019-03-27T14:53:21 < zyp> could be some weird proprietary protocol
2019-03-27T14:53:41 < zyp> I mean, it's ethernet for sure, but everything on top of that could be proprietary
2019-03-27T14:54:35 < zyp> just wrap up shit in an ethernet packet and slap an arbitrary ethertype on it
2019-03-27T14:54:44 < aandrew> zyp: pads on a board is $0 cost. I'm talking about the stupid proprietary cable
2019-03-27T14:55:13 < zyp> aandrew, and I'm talking about the total cost, boards + cable
2019-03-27T14:55:25 < aandrew> no the clip does *not* work fine for extended dbeugging. the alignment pins bend just a bit and then it's worthless; you bend it back but it starts wearing
2019-03-27T14:56:47 < zyp> what does extended mean to you? I've had shit sitting on my desk here more or less permanently hooked up with a clip for the past 1.5 years
2019-03-27T14:58:29 < aandrew> dongs: the tx and rx ends are completely independent
2019-03-27T14:59:04 < aandrew> zyp: I've had them fail within two weeks
2019-03-27T14:59:34 < aandrew> if the pins were threaded and you could use nylon nuts to hold it on the board that wouldn't be a bad fix
2019-03-27T15:00:33 < dongs> this china 60W load is prety cool
2019-03-27T15:00:47 < jadew> which load?
2019-03-27T15:01:19 < aandrew> IMO it's just a highly marketed solution looking for a problem
2019-03-27T15:01:32 < dongs> https://www.ebay.ca/itm/trash/362501528083 this jadew 
2019-03-27T15:01:59 < jadew> it might start oscillating
2019-03-27T15:02:04 < jadew> (easily)
2019-03-27T15:02:32 < jadew> you should give it a try with a sudden load
2019-03-27T15:02:37 < zyp> aandrew, is it really that highly marketed?
2019-03-27T15:02:54 < jadew> if it's ringing, it's not well designed
2019-03-27T15:03:50 < dongs> jadew: i just need to see some crap im reversing under thermal cam when its loaded
2019-03-27T15:03:53 < dongs> i dont need it to be sudden
2019-03-27T15:04:02 < dongs> no problem
2019-03-27T15:05:17 < zyp> from my perspective, tag-connect is cheaper, smaller and more robust than putting a header on every board
2019-03-27T15:05:32 < dongs> ya but then you need to use tag-connect, lol
2019-03-27T15:05:52 < zyp> sure
2019-03-27T15:05:56 < jadew> I think I showed you what I'm using
2019-03-27T15:06:12 < jadew> the footprint is a regular 1.27 header
2019-03-27T15:06:18 < zyp> jadew, probably, this shit comes up over and over again
2019-03-27T15:06:31 < dongs> i just stick to 1.27mm 2x5 header that is standard
2019-03-27T15:06:36 < jadew> so if I want to, I can use a real header, otherwise I can just use the little thing I made
2019-03-27T15:06:45 < dongs> then i rage when jewLink fails to work inverted in it
2019-03-27T15:06:46 < jadew> dongs, same
2019-03-27T15:07:36 < zyp> dongs, I rage when I dig a board out of the box I threw it in and find that all the pins are bent
2019-03-27T15:08:36 < zyp> shrouded headers avoids that, but they are larger and more expensive
2019-03-27T15:09:30 < invzim> 1.27mm shrouded ftw :)
2019-03-27T15:10:45 < jadew> http://5.12.42.67/stuff/20181002_161330.jpg
2019-03-27T15:11:04 < jadew> of course, if you already have a tag connect, you don't need that
2019-03-27T15:11:17 < jadew> but it does work pretty well
2019-03-27T15:11:28 < zyp> what's the pinout of that?
2019-03-27T15:11:43 < jadew> it can be whatever you need it to be
2019-03-27T15:11:55 < zyp> that's the problem :)
2019-03-27T15:12:01 < jadew> depends on the cable you connect to it
2019-03-27T15:12:18 < jadew> it's just an adapter 1 is 1, 6 is 6
2019-03-27T15:12:28 < zyp> whenever you invent your own pinout for something, you end up having to make your own cables to connect to it
2019-03-27T15:12:44 < jadew> ah, I don't invent my own pinout
2019-03-27T15:12:48 < jadew> I use standard pinouts
2019-03-27T15:12:54 < jadew> but I can use it for anything
2019-03-27T15:13:04 < jadew> STM, AVR, SAM, etc
2019-03-27T15:13:18 < jadew> the footprint would have the correct pinout
2019-03-27T15:13:37 < zyp> yeah, sure, but the standard ARM pinout is 2x5, not 2x3
2019-03-27T15:14:27 < jadew> well, you have two choices there, either make your own pinout or make another tool like that that has 10 pins :)
2019-03-27T15:15:11 < zyp> yes
2019-03-27T15:15:14 < jadew> my point is that it works (probably not as well as the tag connect)
2019-03-27T15:15:32 < jadew> but it costs pennies
2019-03-27T15:15:48 < zyp> yeah, and time
2019-03-27T15:16:03 < jadew> true
2019-03-27T15:16:21 < zyp> it's the same point I'd make about a test jig
2019-03-27T15:17:01 < zyp> some people argue it's better to just put swd on test points and make a jig
2019-03-27T15:17:13 < zyp> which is fair enough if you were gonna make the jig anyway
2019-03-27T15:18:15 < karlp> hrm, just found a c library that relies on float equality comparison
2019-03-27T15:18:18 < karlp> nice one.
2019-03-27T15:18:52 < zyp> the way I see it, the advantage of tag-connect is that it's an off the shelf product with its own standardized pinout, you don't need to spend any time cooking up custom solutions
2019-03-27T15:19:08 < karlp> also, hooray, implicit doubles too: https://github.com/romanbsd/statsd-c-client/blob/master/statsd-client.c#L152
2019-03-27T15:19:33 < zyp> haha
2019-03-27T15:19:56 < karlp> was like, "I don't want to specify sampling rate style.. how... wat..."
2019-03-27T15:21:07 < zyp> well, it's not really wrong the way it's used
2019-03-27T15:22:00 < zyp> I mean, if I'm reading it correct, they're omitting the sample rate from the message if it's exactly 1.0
2019-03-27T15:22:08 < karlp> yeah,
2019-03-27T15:22:14 < benishor> some numbers can be exactly represented in IEEE 754
2019-03-27T15:22:19 < benishor> and 1.0 is one of them
2019-03-27T15:22:28 < zyp> benishor, yeah, but that is irrelevant
2019-03-27T15:22:28 < karlp> benishor: yes, but that's a crazy thing to rely on.
2019-03-27T15:22:29 < benishor> so it's ok
2019-03-27T15:22:39 < benishor> zyp: what part is irrelevant?
2019-03-27T15:22:44 < karlp> also, if I type "1.0" in one place it will be 1.0 in the other one too,
2019-03-27T15:22:49 < karlp> even if neither are actually 1.0....
2019-03-27T15:23:00 < benishor> they are always 1.0 actually
2019-03-27T15:23:04 < benishor> that's what I'm saying
2019-03-27T15:23:13 < karlp> yes, but it's still irrelevant because of what I'm saying
2019-03-27T15:23:19 < karlp> it's only a comparison, it's not used as a number
2019-03-27T15:23:21 < zyp> benishor, equality comparison doesn't have anything to do with exact representation
2019-03-27T15:23:28 < benishor> zyp: noshit
2019-03-27T15:23:40 < karlp> it's still _terrible_ style 
2019-03-27T15:23:53 < benishor> nevermind the style, we agree the style is bad
2019-03-27T15:24:01 < benishor> but that particular instance pasted is ok
2019-03-27T15:24:06 < zyp> benishor, you might get issues even if you compare to a number that's exactly representable
2019-03-27T15:24:10 < benishor> be it by pure luck or not
2019-03-27T15:24:17 < karlp> not because of 1.0 being reprensented or not though
2019-03-27T15:24:22 < benishor> zyp: how exactly?
2019-03-27T15:24:24 < karlp> pick one that isn't, 
2019-03-27T15:24:40 < karlp> the 2.0 literal will be "wrong" but will still compar identically to another 2.0 "wrong" literal.
2019-03-27T15:25:00 < benishor> sure, but not to a "pure" 2.0 obtained by a division
2019-03-27T15:25:04 < zyp> benishor, x = 1.0; x /= 3.0; x *= 3.0; if(x == 1.0) ...
2019-03-27T15:25:04 < benishor> or whatever calculation
2019-03-27T15:25:28 < benishor> zyp: that's a stupid example
2019-03-27T15:25:34 < karlp> benishor: no, it's not.
2019-03-27T15:25:43 < karlp> you have no control over where your parameters came from
2019-03-27T15:25:51 < karlp> you should just never be doign float comparison liek this.
2019-03-27T15:25:54 < benishor> first of all 1/3 is not an exactly representable number, it's periodic 
2019-03-27T15:26:08 < zyp> benishor, correct
2019-03-27T15:26:19 < zyp> but the comparison is x == 1.0
2019-03-27T15:26:19 < karlp> minimial changes would probably just make the float arg a pointer, but fuck that.
2019-03-27T15:26:26 < karlp> this is enough to demo it anyway
2019-03-27T15:27:02 < benishor> second of all, I do get your points but judging by the usage, by pure luck that particular instance was ok
2019-03-27T15:28:31 < zyp> I was doing some float bullshittery on monday, I ran through an equation with a bunch of various inputs, and then I wanted a list of all the unique outputs
2019-03-27T15:29:05 < zyp> which meant I had to account for a e-14 or so rounding error between some of them :)
2019-03-27T15:29:37 < benishor> first define "unique" :)
2019-03-27T15:29:47 < benishor> yes, that's usually the way to do it, use an epsilon
2019-03-27T15:30:26 < benishor> however, you need to pay attention since the value of epsilon needs to be adjusted according to the range of the values the floats can have
2019-03-27T15:30:46 < karlp> and we're back tot he initial comment "heh, relyign on float equality checks, dumb"
2019-03-27T15:30:52 < benishor> the greater the values go, the more you should increase the epsilon
2019-03-27T15:31:35 < benishor> a good post on the matter https://blog.demofox.org/2017/11/21/floating-point-precision/
2019-03-27T15:34:03 < zyp> benishor, well, all my inputs were rational, so by "unique" I mean that rounding errors doesn't count :)
2019-03-27T15:34:10 < kakimir> float equality check :o
2019-03-27T15:34:48 < kakimir> is there some equality tolerance in python world or so?
2019-03-27T15:35:06 < zyp> how so?
2019-03-27T15:35:08 < kakimir> or is it bitwise equality always in every language?
2019-03-27T15:36:10 < Laurenceb> aha found the K210 KPU "documentation"
2019-03-27T15:36:37 < Laurenceb> looks like its 8 bit signed in/out using 9 bit signed internally
2019-03-27T15:37:19 < Laurenceb> then pipelined with 64 parallel in/out channels
2019-03-27T15:39:13 < Laurenceb> but there doesnt seem to be full documentation - its passed a little precompiled blob in ram that tells it what to do to convert between two layers
2019-03-27T15:41:08 < Laurenceb> so its probably 5Gpixel/s throughput at 800Mhz
2019-03-27T15:41:25 < zyp> pixels?
2019-03-27T15:41:32 < Laurenceb> erm -  "pixels"
2019-03-27T15:41:36 < zyp> isn't it for neural nets?
2019-03-27T15:41:53 < Laurenceb> yes but its all convolution net based
2019-03-27T15:42:03 < Laurenceb> so x/y array of 8 bit values
2019-03-27T15:42:04 < zyp> yeah?
2019-03-27T15:42:22 < Laurenceb> so probably 5G"values"/s

2019-03-27T16:25:42 < kakimir> is there any reason not use use -g3
2019-03-27T16:25:48 < kakimir> when using IDE for debugging
2019-03-27T16:26:03 < kakimir> does it change anything especially with optimized code?
2019-03-27T16:31:10 < mawk> no, you can use both -O and -g
2019-03-27T16:31:27 < mawk> it's just that gdb may have trouble debugging when the frame pointer is omitted
2019-03-27T16:31:38 < mawk> so if you want to debug you must have -g with -O

2019-03-27T18:16:47 < bitmask> (its noon btw)
2019-03-27T18:16:57 < karlp> what are cyp3a4 inhibitiors when they're at home?
2019-03-27T18:17:23 < bitmask> at home?
2019-03-27T18:18:16 < bitmask> CYP3A4 breaks down opioids, so when you inhibit them and take your medication, the first pass through the liver doesn't do much and more enters your blood stream
2019-03-27T18:19:15 < bitmask> can increase effects and my main goal is to make it last longer
2019-03-27T18:20:12 < bitmask> I think it can actually be pretty dangerous with certain medications, there are warning labels that say not to drink grapefruit juice with some meds
2019-03-27T18:25:09 < karlp> weren't you trying to cut down on your usage?
2019-03-27T18:25:19 < karlp> sounds like you're looking for loopholes.

2019-03-27T19:10:32 < kakimir> I just had some problems with .hex
2019-03-27T19:10:49 < kakimir> I needed to change file type from programming files to intel hex
2019-03-27T19:11:31 < mawk> what's about that .hex
2019-03-27T19:11:33 < mawk> it's horrible
2019-03-27T19:11:41 < kakimir> ye
2019-03-27T19:11:41 < mawk> it's for proper encoding through serial port ? I see no other use
2019-03-27T19:11:53 < kakimir> I just
2019-03-27T19:12:20 < kakimir> wanted to give binary to someone without revealing anything extra
2019-03-27T19:12:28 < mawk> you can strip the elf
2019-03-27T19:12:39 < kakimir> sorry .hex worked for me
2019-03-27T19:12:43 < mawk> lame
2019-03-27T19:12:47 < kakimir> sorry

2019-03-27T22:54:06 < jadew> (I only read the text on the second page)

2019-03-27T23:06:57 < mawk> I saw lots of these in the NL
2019-03-27T23:07:03 < mawk> it's just a fancy name for kebab
2019-03-27T23:07:09 < mawk> it's like "tacos"
2019-03-27T23:07:16 < mawk> just kebab in disguise
2019-03-27T23:20:37 < Steffanx> lies.
2019-03-27T23:21:27 < jadew> apparently there is a difference
2019-03-27T23:21:45 < jadew> shawarma is a subtype of kebab
2019-03-27T23:22:19 < Steffanx> Try https://schooltv.nl/video/het-klokhuis-shoarma-en-kebab/ in your best dutch mawk
2019-03-27T23:22:31 < jadew> also, I don't think I've ever eaten tacos, unless what taco bell serves are tacos
2019-03-27T23:23:19 < Cracki> remember the franchise wars? all restaurants are taco bell now
2019-03-27T23:23:43 < jadew> well, they've opened one here and I went with my wife
2019-03-27T23:23:48 < jadew> we didn't like the food
2019-03-27T23:24:14 < jadew> nor the atmosphere - lots of teens, being cool

2019-03-27T23:24:59 < Cracki> ah you mean taco bell ¯\_(ツ)_/¯
2019-03-27T23:25:47 < Steffanx> You're getting old jadew
2019-03-27T23:26:09 < Cracki> in germany, doner kebab meat must be at most half minced meat. the skewers they show in that video look like meatloaf
2019-03-27T23:26:19 < jadew> Steffanx, probably
2019-03-27T23:28:16 < jadew> the only other interesting, rolled food I ever ate was some mexican stuff that was called tortilla - maybe that was a form of taco?
2019-03-27T23:28:30 < jadew> *other than shawarma
2019-03-27T23:28:43 < Cracki> I think those canbe summed up as "wraps"
2019-03-27T23:29:15 < jadew> looked a lot like a shawarma
2019-03-27T23:29:40 < jadew> the place went bankrupt within two months
2019-03-27T23:29:52 < Cracki> might have been a front for money laundering? :>
2019-03-27T23:30:01 < Cracki> or nobody went there twice
2019-03-27T23:30:02 < jadew> don't know, it looked really good
2019-03-27T23:30:10 < jadew> probably that
2019-03-27T23:30:45 < Cracki> my go-to place around here is some asian place. cheap, plenty, and some stuff is always already cooking so there's almost no wait
2019-03-27T23:31:07 < Cracki> also edible of course :>
2019-03-27T23:31:32 < jadew> asians know how to grill a cat
2019-03-27T23:32:13 < jadew> the only good chinese places near me are super expensive
2019-03-27T23:32:26 < jadew> they felt expensive even when I had money
2019-03-27T23:32:27 < Cracki> a while ago I started noticing halal cert markings... I'm not sure if they actually kill the animals according to that horrible cruel custom. it's legal to slaughter animals that way outside the country and then import the meat
2019-03-27T23:32:54 < jadew> not sure what that is
2019-03-27T23:33:00 < Cracki> any place here is expensive if it's nearly the only one for 100 meters
2019-03-27T23:33:14 < Cracki> halal means animal must be bled out alive
2019-03-27T23:33:37 < jadew> ah
2019-03-27T23:33:49 < jadew> doesn't sound that bad compared to our customs
2019-03-27T23:34:01 < Cracki> the kosher markings are a lot harder to spot because they're usually just a U in a circle or something
2019-03-27T23:34:02 < jadew> (regarding pigs that is)
2019-03-27T23:34:12 < Cracki> what's your custom with pigs?
2019-03-27T23:34:24 < jadew> it's not legal now, but in here people would first cut the pigs testicles
2019-03-27T23:34:30 < jadew> then stab it and let it bleed
2019-03-27T23:34:34 < Cracki> uh
2019-03-27T23:34:41 < Cracki> why would one do that?
2019-03-27T23:35:39 < jadew> I think the reasoning behind that was that when being stabbed he would release some substance from his balls into his blood and the meat wouldn't be as good
2019-03-27T23:35:49 < Cracki> lol
2019-03-27T23:36:06 < Cracki> I heard somewhere in asia they torture puppies to death because that makes the meat taste sweeter
2019-03-27T23:36:08 < karlp> there's a few different methhods that are halal.
2019-03-27T23:36:19 < jadew> another explanation I've heard, was that what the people were perceiving as bad was normal, while with its testicles cut as "improved"
2019-03-27T23:36:59 < jadew> because due to the pain, the pig would actually release something: adrenaline
2019-03-27T23:37:14 < Cracki> well yeah I get how throat slitting is an expedient way to kill something... but today we have more painless and quick methods
2019-03-27T23:38:27 < jadew> and yeah, if you think about the adrenaline thing, it makes sense about the puppies too
2019-03-27T23:38:54 < Cracki> something to be aware of with these halal/kosher certifications: somewhere along the supply chain, someone has to pay for it, and the money is used for various religious purposes, some one might find questionable at least
2019-03-27T23:39:19 < jadew> this had nothing with religion
2019-03-27T23:39:26 < Cracki> I realize that
2019-03-27T23:39:48 < Cracki> which is why I mentioned _that_ aspect surrounding some of these practices
2019-03-27T23:40:12 < jadew> it's not legal in here anymore
2019-03-27T23:40:25 < karlp> Cracki: wind down the hate hey?

2019-03-28T01:44:27 < jadew> but 0.1 mm total
2019-03-28T01:44:42 < jadew> nah, it's a matter of how it looks
2019-03-28T01:44:48 < jadew> I don't want that shitty slot visible
2019-03-28T01:45:02 < Cracki> it's ruined
2019-03-28T01:45:32 < jadew> I have two other options
2019-03-28T01:45:38 < jadew> one is too thin, the other is too thick
2019-03-28T01:49:54 < jadew> the alps version is worse
2019-03-28T01:50:19 < jadew> thick and conical

2019-03-28T04:12:52 < dongs> ok, lunix fags
2019-03-28T04:13:02 < dongs> i am remote connected to a windows machine and it has 2 interfaces
2019-03-28T04:13:11 < dongs> lan is connected to wahtever and gateway is 192.168.1.1
2019-03-28T04:13:21 < dongs> im also conencted to some gay fucking thermostat
2019-03-28T04:13:27 < dongs> who also decided its gateway to be 1.1
2019-03-28T04:13:33 < dongs> mac address in arp -a is different
2019-03-28T04:13:41 < dongs> how the fuck do i force going to 192.168.1.1 (the thermostat)
2019-03-28T04:14:30 < dongs> obviously changing any of those is beyond these people capabilities as they can't even grasp the concept of conencting to thermostat to make it connect to other network
2019-03-28T04:14:40 < dongs> and i can't drop out of lan because thats how im remotely conencted ot the machine

2019-03-28T04:32:38 < englishman> can you change gateway to 0.1 and reconnect
2019-03-28T04:33:02 < dongs> tyes

2019-03-28T04:33:09 < dongs> i cant cahnge anything on the netwrok
2019-03-28T04:33:14 < englishman> what thermostat
2019-03-28T04:33:19 < dongs> some honeywell trash
2019-03-28T04:33:30 < englishman> better call tech support
2019-03-28T04:35:35 < englishman> when they decide to take a 1.1 ip isnt it usually when you connect your phone to its host wifi
2019-03-28T04:35:38 < englishman> to set it up
2019-03-28T04:35:53 < englishman> then go back to normal wifi after setting shit up and it uses dhcp
2019-03-28T04:36:12 < dongs> yes.............
2019-03-28T04:36:21 < dongs> that is literalyl the part these fucktards cant figure out how to do
2019-03-28T04:36:23 < englishman> can your grandma use a phone
2019-03-28T04:36:30 < englishman> rip
2019-03-28T04:36:31 < dongs> the concept of disconnecting from wifi and connecting to something else

2019-03-28T04:41:04 < dongs> it has a 10 minute timeout
2019-03-28T04:41:13 < dongs> of when it can do wifi connect to home network
2019-03-28T04:41:21 < dongs> after that you ahve to rip it out of socket

2019-03-28T04:53:25 < jadew> dongs, you can add a gw for your ip on that machine, to use that interface
2019-03-28T04:53:30 < jadew> then you remove the default gw
2019-03-28T04:53:48 < jadew> no
2019-03-28T04:53:49 < dongs> that would disconnect my remote serssion
2019-03-28T04:53:56 < jadew> it wouldn't
2019-03-28T04:54:00 < jadew> but it wouldn't work either
2019-03-28T04:54:27 < jadew> you kind of have to bind to connection to one interface
2019-03-28T04:54:36 < jadew> *the
2019-03-28T04:54:42 < jadew> *the connection
2019-03-28T04:54:54 < jadew> not sure how that can be achieved
2019-03-28T04:54:58 < jadew> can probably be done
2019-03-28T04:55:20 < jadew> wait
2019-03-28T04:55:30 < jadew> those interfaces don't happen to have the same ip address?
2019-03-28T04:56:10 < Thorn> when I had a .0.1 device on my 192.168.1/24 network I could add another source address in the 192.168.0/24 range to my network interface (linux can do that) but you can't have the same address in 2 different ranges (and therefore routes)

2019-03-28T04:59:04 < dongs> err
2019-03-28T04:59:10 < dongs> well i geuss that link is ok
2019-03-28T04:59:11 < dongs> whatever
2019-03-28T05:00:11 < jadew> a proper solution would be to take .1 out of the IP pool
2019-03-28T05:00:32 < jadew> more like a work around, but still, it's not a router
2019-03-28T05:04:11 < Thorn> you can't remove the default gateway or make it unroutable on a remote machine without losing connectivity to that machine
2019-03-28T05:04:31 < jadew> that's why I said he should add a gw for his IP first
2019-03-28T05:05:02 < jadew> but the fact that that is a GW is not really the issue
2019-03-28T05:05:15 < jadew> the issue is that the GW is in his subnetwork
2019-03-28T05:05:23 < jadew> just like the thermometer

2019-03-28T12:22:31 < dongs> beacuse you have laptop connected to ethernet

2019-03-28T12:24:18 < dongs> there's no fucking reason that shit needs to be at 1.1
2019-03-28T12:24:21 < englishman> I fail to see the problem, unless you soldered that ethernet cord to your laptop
2019-03-28T12:24:40 < karlp> englishman:yes, you have to unplug the ethernet cable, lose the internet whiel you configure
2019-03-28T12:24:41 < Laurenceb_> mine buttcoin with K210
2019-03-28T12:24:42 < dongs> in fact most non-retarded products prolly pick a super random ip/dhcp IP, then have a local DNS server where you go to someshit like gayshit.setup
2019-03-28T12:24:45 < dongs> and it will automatically work

2019-03-28T12:25:44 < karlp> 99% of hoem routers assign 192.168.1/24.
2019-03-28T12:25:45 < englishman> no
2019-03-28T12:25:51 < englishman> there is equal chance of conflict
2019-03-28T12:25:56 < karlp> wat?!

2019-03-28T12:26:26 < dongs> if you pick 192.168.14.88 i guarantee you there's not gonna be a conflict except in some 0.0000001% chance

2019-03-28T12:26:44 < englishman> doesn't matter, you connect to its ap, done
2019-03-28T12:26:46 < englishman> no conflict

2019-03-28T12:27:16 < englishman> everyone has phones and can connect them to wifi
2019-03-28T12:27:21 < karlp> deliberating making that option hard/impossible is _dumb_ when it's free to not do it.
2019-03-28T12:27:35 < englishman> maybe just follow the instructions
2019-03-28T12:27:48 < karlp> no way  man, you're fucking wildly wrong on this one :)
2019-03-28T12:27:49 < englishman> connect your phone to its wifi
2019-03-28T12:27:51 < dongs> englishman works for honeywell IoT division confirmed
2019-03-28T12:27:58 < englishman> and set it up
2019-03-28T12:28:30 < englishman> maybe time to get your grandma a better wifi router if she has to use ethernet

2019-03-28T15:32:13 < kakimir> my ADC value is off by 30mV
2019-03-28T15:32:24 < kakimir> or at least the conversion

2019-03-28T15:33:00 < Thorn> Kakimir Precision Labs LLC
2019-03-28T15:36:33 < jpa-> too high source impedance vs. sampling time
2019-03-28T15:38:17 < kakimir> I mean like 24bit resolution
2019-03-28T15:38:59 < kakimir> world's first microcomputer chipset read data from 20bit ADC
2019-03-28T15:40:03 < karlp> kakimir: are you on stm32 or still on infineion stuff<z?
2019-03-28T15:41:35 < kakimir> currently debugging xmc1100
2019-03-28T15:41:59 < kakimir> my M0 runs on 5volts
2019-03-28T15:43:43 < kakimir> interesting
2019-03-28T15:44:25 < kakimir> I see the result of ADC is not completed
2019-03-28T15:44:43 < kakimir> that is why VF flag never sets
2019-03-28T15:46:10 < kakimir> values from ADC are dec:32 appart at minimum
2019-03-28T15:46:27 < kakimir> fuu fuu
2019-03-28T15:47:57 < kakimir> that equals 7bit ADC
2019-03-28T15:48:05 < kakimir> does this thing even have 7bit
2019-03-28T15:48:43 < kakimir> or is 7bits all it can do before I omit reading of VF flag and read result
2019-03-28T15:52:30 < kakimir> it doesn't have 7bit
2019-03-28T15:52:44 < kakimir> good thing I checked
2019-03-28T15:53:23 < kakimir> VADC->GLOBICLASS[0] |= (0x01UL << VADC_GLOBICLASS_CMS_Pos);           // Select 10-Bit conversion for channel 0.
2019-03-28T15:53:45 < kakimir> my ADC code is still a shitshow
2019-03-28T15:56:47 < kakimir> now I have 9bit precision
2019-03-28T15:57:05 < kakimir> so I get -3bits from what I choose
2019-03-28T16:10:07 < kakimir> I found another arduino example

2019-03-28T16:38:39 < kakimir> arduino example did it
2019-03-28T16:38:59 < kakimir> (done by Infineon)
2019-03-28T16:39:36 < kakimir> I still lack 3bits out of the resolution
2019-03-28T16:40:50 < kakimir> let's try to have some additional sampling time (that should be for EMUX)
2019-03-28T16:42:10 < kakimir> oh wait there is separate for standard conversions
2019-03-28T16:43:53 < kakimir> there is no headsup though that you need to manually add sampling time for 12bit conversions
2019-03-28T16:49:39 < kakimir> hey
2019-03-28T16:50:01 < kakimir> me dumb
2019-03-28T16:50:14 < kakimir> I'm looking at accumulated values
2019-03-28T16:50:22 < kakimir> I have ACC = 8

2019-03-28T22:20:18 < Laurenceb> does this exist?

2019-03-28T22:22:01 < Laurenceb> no its self powered from the usbc port
2019-03-28T22:22:17 < aandrew> Laurenceb: I'm almost 100% certain I have several hubs that do that
2019-03-28T22:22:26 < aandrew> oh wait

2019-03-28T22:22:27 < Cracki> (self-powered as in it has its own wall wart)

2019-03-28T22:23:01 < Cracki> and no I have never encountered usb c hubs that request 20 volts from upstream
2019-03-28T22:23:12 < englishman> why 20v
2019-03-28T22:23:20 < englishman> usbc supports 5v@5a
2019-03-28T22:23:31 < Laurenceb> hmm ok
2019-03-28T22:23:38 < englishman> good luck finding any power supply that does it tho

2019-03-28T22:23:45 < Laurenceb> grrr
2019-03-28T22:23:57 < englishman> yeah, that 100w spec comes from 20v@5a
2019-03-28T22:24:00 < Laurenceb> I should look up the spec on thinkpad c port
2019-03-28T22:24:07 < englishman> which requires smart-tagged cables
2019-03-28T22:24:11 < Cracki> that amazon link... how is that powered? it talk about being capable of passing through 20 volts...
2019-03-28T22:24:30 < Laurenceb> Cracki: yeah if it has another usbc plugged in...
2019-03-28T22:24:47 < Cracki> hm so that might suit you?
2019-03-28T22:26:47 < Laurenceb> according to forumz it supports prfile 4

2019-03-28T22:32:58 < ub|k> Cracki: I have one too. I just wanted to confirm the I2C address of the DAC
2019-03-28T22:32:58 < Cracki> official disco board or nucleos are an option too
2019-03-28T22:33:00 < englishman> ha, it looks like 5v@5a is not supported
2019-03-28T22:33:11 < englishman> only 20v allows >3a
2019-03-28T22:33:13 < ub|k> which should be 0x94 (or 0x4a in 7-bit)
2019-03-28T22:33:20 < Cracki> the... what? your board has an i2c-attached dac?
2019-03-28T22:33:38 < ub|k> Cracki: yes, it's got a CS43L22
2019-03-28T22:33:53 < Cracki> then you should go by https://www.mouser.com/ds/2/76/CS43L22_F2-1142121.pdf
2019-03-28T22:34:24 < Cracki> only variables are either address bits to that chip, or description of i2c considering 7-bit address, or "8"-bit address (with r/w LSB)
2019-03-28T22:34:45 < ub|k> Cracki: i have that doc, but it doesn't tell me what the address will be
2019-03-28T22:36:40 < ub|k> my logic analyzer tells me that the address is OK... but I still get NACK
2019-03-28T22:36:52 < Cracki> it has an AD0 pin so that's that... chapter 5.0.1 shows a diagram that *might* contain the actual address
2019-03-28T22:36:54 < ub|k> maybe i'm not initalizing the CS43L22 properly?

2019-03-28T22:37:52 < Cracki> not sure how you get 4a
2019-03-28T22:38:01 < ub|k> Cracki: if you add the 0 afterwards
2019-03-28T22:38:06 < Cracki> if you interpret it as 1001010_0 and 1001010_1
2019-03-28T22:38:11 < ub|k> yeah
2019-03-28T22:38:16 < Cracki> then I get 148/149
2019-03-28T22:38:38 < ub|k> 74 decimal = 0x4a
2019-03-28T22:38:51 < Cracki> yes, and what's 94?

2019-03-28T23:01:46 < ub|k> that's how i'm seeing i get a NACK
2019-03-28T23:01:47 < Cracki> so you ARE the same dude?
2019-03-28T23:01:48 < englishman> msp430 has known errata for i2c above 50kHz
2019-03-28T23:01:54 < englishman> fucking garbage
2019-03-28T23:02:23 < ub|k> Cracki: no
2019-03-28T23:02:24 < Cracki> or were there several dudes with i2c within the last week...
2019-03-28T23:02:44 < kakimir> he certainly is Cracki
2019-03-28T23:02:59 < ub|k> i never asked anything about I2C on here
2019-03-28T23:03:11 < ub|k> and i only started working on this today
2019-03-28T23:03:13 < ub|k> so, not me :p

2019-03-28T23:04:00 < Cracki> try it, might work

2019-03-28T23:04:44 < ub|k> nope
2019-03-28T23:05:03 < kakimir> how is your address line connected in the slave?
2019-03-28T23:05:13 < ub|k> kakimir: this is a discovery board
2019-03-28T23:05:19 < Cracki> which exact one
2019-03-28T23:05:32 < kakimir> let's dive into details
2019-03-28T23:05:34 < ub|k> like this one: https://www.st.com/en/evaluation-tools/stm32f4discovery.html
2019-03-28T23:05:44 < kakimir> is it like it or the exact one?
2019-03-28T23:05:47 < ub|k> (aliexpress knockout)
2019-03-28T23:05:59 < Cracki> and what happens when you try one of the provided examples?

2019-03-28T23:06:29 < ub|k> Cracki: haven't tried the provided examples yet
2019-03-28T23:06:29 < kakimir> knockout :o
2019-03-28T23:06:33 < ub|k> good point
2019-03-28T23:06:38 < Cracki> check the board's data sheet. maybe you have to set some jumpers
2019-03-28T23:06:47 < kakimir> examples are there because those examples work
2019-03-28T23:06:52 < Cracki> iirc htey have a few
2019-03-28T23:06:57 < ub|k> kakimir: i know, it's a good point

2019-03-28T23:06:59 < ub|k> lemme see

2019-03-28T23:08:06 < Cracki> i never read the titles of data sheets
2019-03-28T23:10:44 < kakimir> you just lectioned him for reading datasheets

2019-03-28T23:45:11 < englishman> fucking msp430
2019-03-28T23:46:54 < kakimir> is it architecture dependant to have bitfields

2019-03-28T23:47:57 < englishman> yeah I guess cuz ti trash can't read across registers
2019-03-28T23:48:23 < englishman> portable enough, who gives a shit about ancient 8butt
2019-03-28T23:48:29 < englishman> you can port it from arm to arm

2019-03-29T00:30:00 < kakimir> and nothing is pulling SDA down
2019-03-29T00:30:30 < ub|k> ok i see
2019-03-29T00:30:43 < kakimir> your i2c handler stops
2019-03-29T00:32:00 < kakimir> if it did some error handling there and released i2c bus it both would go up after that
2019-03-29T00:32:40 < ub|k> funny, because i think my code never realizes there has been a NACK
2019-03-29T00:32:57 < ub|k> from the debugger output I can see that it's stuck reading SR1

2019-03-29T00:44:29 < ub|k> supposedly the ADDR field in SR1 gets cleared when the address is sent
2019-03-29T00:44:33 < ub|k> kakimir: what do you mean?
2019-03-29T00:44:44 < kakimir> some cases you don't really have like.. reason to handle errors
2019-03-29T00:45:06 < kakimir> just let it stuck get it in while(1) trap and let watchdog to bootcycle it
2019-03-29T00:46:07 < karlp> ub|k is having basic problems with the cirrus part on the f4 disco though right?
2019-03-29T00:46:30 < kakimir> well getting it to stuck correctly and then wait for watchdog can be concidered "error handling"
2019-03-29T00:46:35 < karlp> does it work with some demo code form somewhere or hgave you never had it working?

2019-03-29T00:52:56 < karlp> was not having the right pullups, so LA was giving misleading info.

2019-03-29T00:58:29 < karlp> boundless optimisim and the lies of a nicely privately held company kept it up to the last second.
2019-03-29T00:58:49 < karlp> airline companies tend to be in theh "everything's ok, no problem" right up to the very last second.
2019-03-29T00:58:50 < zyp> what's WOW? .is LCC?
2019-03-29T00:59:02 < karlp> was an airline based here.
2019-03-29T00:59:14 < zyp> LCC?
2019-03-29T00:59:20 < karlp> I've no idea what lcc means.
2019-03-29T00:59:25 < zyp> low-cost carrier
2019-03-29T00:59:26 < karlp> wow is the airline name.
2019-03-29T00:59:29 < zyp> i.e. shit
2019-03-29T00:59:40 < karlp> I guess, yes, but whaht's not a low cost carrier these days.
2019-03-29T00:59:51 < karlp> they're all buses in the sky
2019-03-29T01:00:20 < zyp> a good rule of thumb is whether you have to pay extra to bring luggage or not
2019-03-29T01:00:23 < karlp> they claim they misstepped when thehy expaned into long haul and wideboyd shit, should have stuck to their core competence of cheap 
2019-03-29T01:00:58 < englishman> everyone charges for luggage now
2019-03-29T01:00:59 < karlp> they really just never made money, and it was all just "get big, it will work out"
2019-03-29T01:01:12 < karlp> yeah, luggage is only "free" on long long haul.
2019-03-29T01:01:22 < karlp> enve the "fancy" airlines just offer cheaper seats with no luggagte now
2019-03-29T01:01:44 < karlp> englishman:I feel bad for anyone who wasn't seeing what was happenin ghere though, and just bopught tickets in the last week or so though.
2019-03-29T01:01:44 < zyp> really?
2019-03-29T01:02:09 < englishman> yeah it sucks
2019-03-29T01:02:26 < englishman> especially if you could just barely afford your trip in the first place
2019-03-29T01:02:30 < karlp> englishman:this is from the newspaper this week:https://www.visir.is/g/2019190328989/halldor-27.03.19
2019-03-29T01:02:51 < karlp> the caption is, "we jsut need skuli to say everytthign will be ok"
2019-03-29T01:02:59 < karlp> skuli is/was the owner of wow.
2019-03-29T01:03:10 < englishman> nice
2019-03-29T01:03:33 < karlp> the smoek came out in nov/ or so.
2019-03-29T01:04:04 < karlp> they wer elike, "oh yeahh, ummm, we need to do abond offering to make sure we have enough cash flow to reach public offerings of our profitable company next year"#
2019-03-29T01:04:20 < karlp> bond offering miraculously was filled at the last minute.
2019-03-29T01:04:32 < karlp> zero transparency as to who/if anyone ever subscribed
2019-03-29T01:04:40 < karlp> hooray private companies.
2019-03-29T01:05:12 < karlp> they then annouced that a finance firm (one of wizzair's backers) was investing in them for ~50% or so, everything gonna be fine.
2019-03-29T01:05:24 < karlp> fast forward to last week, that "out of the blue" fell through,
2019-03-29T01:05:45 < karlp> I bet they'd been stonewalled on seeing real figures and finally got them and dropped it like it's hhot
2019-03-29T01:05:57 < karlp> then it was "in talks with icelandair about a merger"
2019-03-29T01:06:04 < karlp> that was about 5 hours.
2019-03-29T01:06:14 < karlp> "not in our shareholder interest at this point" :)
2019-03-29T01:06:25 < karlp> there's _zero_ value in the company beyond the brand.
2019-03-29T01:06:26 < englishman> rip
2019-03-29T01:06:38 < karlp> all planes leased, they'ðd been sold back years ago to try and keep cash flow up.
2019-03-29T01:06:47 < karlp> so there's what, airport berthing rights?
2019-03-29T01:06:54 < karlp> hooray
2019-03-29T01:07:14 < englishman> in other news, Lululemon is making shit tons of money selling $250 Chinese running pants
2019-03-29T01:07:25 < englishman> stock went up like %15
2019-03-29T01:07:31 < englishman> after earnings
2019-03-29T01:07:46 < karlp> nice
2019-03-29T01:07:59 < karlp> the tradition of "smart" and "technical" and "lifestayle" clothes continues to do wonders
2019-03-29T01:08:12 < englishman> all the fashion shit is going to be big before the next depression
2019-03-29T01:08:14 < karlp> "are you not paying enoughh for clothhes? now you can!"
2019-03-29T01:08:19 < englishman> $aapl is going up
2019-03-29T01:08:21 < englishman> tsla
2019-03-29T01:08:36 < karlp> I mean, we all know it's magic money
2019-03-29T01:08:36 < zyp> hmm, I went checking up what rights you have if your airline goes bankrupt on you after you buy tickets
2019-03-29T01:08:47 < karlp> but you can't short shit too far in advance....
2019-03-29T01:09:07 < karlp> zyp:you join the fucking queue of creditors and hope you bought your tickets on your ccard
2019-03-29T01:09:20 < zyp> the primary thing seems to be getting your money back through a chargeback
2019-03-29T01:09:28 < englishman> yep
2019-03-29T01:09:39 < englishman> or travel insurance if your cc doesn't include it already
2019-03-29T01:10:21 < karlp> apparently it's not fraud to sell tickets even the day before you declare bankruptcy either
2019-03-29T01:10:41 < karlp> though I've heard some of the online booking services had dropped wow from all routing lookups for a week or so now.
2019-03-29T01:10:55 < zyp> hmm
2019-03-29T01:11:23 < karlp> places like kiwi guarantee transfers and shit, no way they'd want to take the risk 
2019-03-29T01:11:25 < zyp> apparently norway also has «reisegarantifondet» which is apparently some insurance shit for package trips
2019-03-29T01:11:43 < karlp> yeah, we probably got that law form you.
2019-03-29T01:11:49 < karlp> only applies to packages though probably.
2019-03-29T01:11:54 < zyp> yeah
2019-03-29T01:12:06 < karlp> so "travel agents" have to reimburse, and they join the creditors queue.
2019-03-29T01:12:59 < englishman> good luck getting your money back, bill and teds travel agency
2019-03-29T01:12:59 < karlp> anyway, at least theh state didn't get involved (this time)
2019-03-29T01:13:18 < karlp> yeah, wife's travel agency doesn't do flights
2019-03-29T01:13:26 < karlp> no way of making a margin, no gain for them,
2019-03-29T01:13:31 < karlp> only risk
2019-03-29T01:13:45 < zyp> englishman, no, you get it from this insurance shit, and then it's not your problem anymore
2019-03-29T01:14:08 < karlp> I think english meant for thhe operator of the small travel agency
2019-03-29T01:14:21 < zyp> ah, fair
2019-03-29T01:16:21 < zyp> today I picked up some 6m long pieces of rebar, brought them home with the egolf

2019-03-29T01:18:49 < zyp> ended up also buying a 5m long wooden beam that I strapped them to, so I could just strap the whole thing on the roof

2019-03-29T01:44:43 < kakimir> for what?
2019-03-29T01:45:22 < zyp> good enough if you're tuning a NFC antenna, kinda useless for most other interesting uses
2019-03-29T01:45:22 < Thorn> for radio. no ISM bands < 100 MHz (at least nothing popular afaik)

2019-03-29T10:35:34 < marble_visions> jadew: your southern neighbor's central fiscal authority had its servers accidentally ddos-ed since a recent law made mandatory all fiscal devices report every sale in realtime. they passed the law despite all warnings that they can't handle the traffic
2019-03-29T10:36:00 < marble_visions> it was in the news

2019-03-29T11:41:19 < PaulFertser> zyp: yep
2019-03-29T11:41:54 < zyp> over here, only some chains do online receipts
2019-03-29T11:42:27 < zyp> ikea has a database I can log into to find all my old receipts, and there's a couple of companies that emails me a receipt each time I shop from them

2019-03-29T11:50:48 < PaulFertser> zyp: e.g. here's some Auchan receipt: https://consumer.1-ofd.ru/#/ticket/586f05e0-d064-43e6-80d3-6132326381c0
2019-03-29T11:51:26 < zyp> nice
2019-03-29T11:52:26 < zyp> do you still need to get the paper receipt to get the code to access it, or can you somehow have it assigned to you so you can just look it up later?
2019-03-29T11:55:10 < PaulFertser> zyp: according to the law you can ask the merchant before the paper receipt is printed to send the copy via "phone number" (no idea how) or "email". But paper receipt must be printed in any case, unless it's an Internet-shop.
2019-03-29T11:55:28 < PaulFertser> I have never tried to do that though, I might try the next time I'm shopping.
2019-03-29T11:55:35 < zyp> ah
2019-03-29T11:56:39 < PaulFertser> Hm, it's written when "phone number" is used the receipt (probably URL to it) is sent via SMS.
2019-03-29T11:56:44 < zyp> over here, it's so common that people don't care about receipts that many stores only print it if you want it
2019-03-29T11:58:05 < zyp> I only get one if there's a chance I'd want to return or complain about something later
2019-03-29T11:58:14 < PaulFertser> Here that would be punishable by a hefty fine.
2019-03-29T12:01:44 < zyp> what part of it? the store not printing it?
2019-03-29T12:02:41 < kakimir> what is CPU lockup reset?
2019-03-29T12:02:42 < PaulFertser> Yes, not printing (for whatever reason).
2019-03-29T12:02:46 < kakimir> what does it look for?
2019-03-29T12:03:04 < Thorn> zyp: some stores have a sign that says "if you don't get a receipt the salesperson pays for your order"
2019-03-29T12:04:49 < zyp> I think the point here is to reduce waste and littering
2019-03-29T12:05:17 < kakimir> cpu lockup == hardfault?
2019-03-29T12:05:55 < zyp> you of course always have the right to get a receipt, but if you don't want it, it's kinda wasteful to print it in the first place
2019-03-29T12:07:24 < Thorn> kakimir: in cortex-m lockup happens when you hard fault while in a hard fault handler
2019-03-29T12:07:46 < Thorn> google double fault lockup
2019-03-29T12:08:10 < zyp> technically it's a triple fault, I believe
2019-03-29T12:08:40 < zyp> most hardfaults are other faults that are promoted to hardfault because they are not handled separately
2019-03-29T12:09:51 < zyp> if you get a busfault, primary handler is the busfault handler, if it's disabled or faults on its own, you get a hardfault
2019-03-29T12:10:11 < zyp> and if the hardfault handler again faults or is not executable, you get a lockup
2019-03-29T12:10:40 < zyp> primary reason, I figure, would be if you fuck up the hardfault vector
2019-03-29T12:13:39 < kakimir> hardfault in hardfault
2019-03-29T12:13:44 < kakimir> can we go deeper

2019-03-29T12:15:06 < karlp> why would it be a hefty fine for pauls case then? 
2019-03-29T12:15:11 < zyp> «if our staff doesn't follow policy, please help us punish them»
2019-03-29T12:15:23 < kakimir> do your chips have parity check in sram?
2019-03-29T12:15:39 < zyp> the TI RM46 certainly has
2019-03-29T12:16:06 < PaulFertser> karlp: sales staff might want to put money in their pocket, that's possible when they do not issue receipt. Also they make the company suspectible to a big fine. So the company tries to take measures against that.
2019-03-29T12:16:15 < kakimir> xmc1100 has it
2019-03-29T12:16:27 < kakimir> flash ecc too but probs not uncommon
2019-03-29T12:16:27 < karlp> why would the company get a fine, for doing what?
2019-03-29T12:16:38 < PaulFertser> karlp: the law requires companies to always issue receipts. For proper taxation.
2019-03-29T12:16:43 < Thorn> some stm32 do have parity in sram iirc
2019-03-29T12:16:53 < karlp> I mean, there's also the store invoice, why would the customer need one to prevent internal fraud?

2019-03-29T12:21:32 < zyp> most customers here pays with card, so the cashier doesn't really have the opportunity to pocket the money

2019-03-29T15:06:26 < enh> I've got a question. What is the minimum set of connections to use STLink with a STM32F3 MCU?
2019-03-29T15:11:11 < aandrew> gnd, swdio and swdck
2019-03-29T15:11:14 < aandrew> er and reset
2019-03-29T15:11:15 < aandrew> so four
2019-03-29T15:11:49 < Thorn> reset is not always necessary
2019-03-29T15:12:17 < Thorn> you may also need Vtarget for a real standalone st-link
2019-03-29T15:12:36 < Thorn> to power the output buffer
2019-03-29T15:13:52 < aandrew> yes true on both counts
2019-03-29T15:15:12 < Thorn> a virgin never programmed stm32 will be in lockup but I still don't think reset is necessary to take it out of lockup
2019-03-29T15:15:27 -!- con3 [~kvirc@ml.sun.ac.za] has quit [Quit: KVIrc 4.9.2 Aria http://www.kvirc.net/]
2019-03-29T15:27:31 < aandrew> wouldn't that depend on BOOT

2019-03-29T15:30:48 < enh> Can you please have a look at this diagram?
2019-03-29T15:31:19 < aandrew> enh: might be better if it wasn't a 404
2019-03-29T15:31:50 < enh> indeed
2019-03-29T15:32:45 < Thorn> worked for me, boot0 is gnded via 510Ω (why resistor?)
2019-03-29T15:33:14 < karlp> 404s here
2019-03-29T15:33:40 < enh> http://s000.tinyupload.com/index.php?file_id=05533198074363488982
2019-03-29T15:34:06 < enh> Sorry for that. Filebin is not working, nor file.io. 
2019-03-29T15:34:27 < aandrew> I always put a resistor on BOOT0, makes it much easier to temporarily strap it the other way
2019-03-29T15:34:48 < enh> https://oshpark.com/shared_projects/c2k0aREr
2019-03-29T15:34:54 < enh> This is the board
2019-03-29T15:36:02 < enh> The BOOT0 resistor is there, aandrew. Top right, I belive.
2019-03-29T15:36:08 < enh> believe. Sorry.
2019-03-29T15:36:21 < aandrew> yep I see it
2019-03-29T15:36:46 < enh> The bottom left symbol in the diagram represents the PCB template.
2019-03-29T15:36:48 < aandrew> a board so big and they didn't break out all the I/O. weird.
2019-03-29T15:36:50 < karlp> interesting use of kicad ports.
2019-03-29T15:36:52 < karlp> I just name the nets.
2019-03-29T15:37:12 < karlp> why did you make your schematic symbol have 12 pins per side? do you hate your readers?
2019-03-29T15:37:17 < enh> It is big like that because it is a template for other modules.
2019-03-29T15:37:29 < aandrew> usually you put a 100nF cap on reset to ground and something like 10k to +V as well to generate a power-on reset
2019-03-29T15:37:37 < aandrew> not necessary I don't think but convention
2019-03-29T15:38:02 < enh> I can change that.
2019-03-29T15:38:04 < aandrew> I think whoever made the board just made the schematic symbol match the part, which is silly
2019-03-29T15:38:04 < karlp> if you're using an m3 part, I recommend breakign out SWO too.
2019-03-29T15:38:15 < aandrew> yes +1 for SWO
2019-03-29T15:38:39 < karlp> there's a nice pdf from ST that says "getting started with stm32XX hw development" that covers this all nicely, without any cargo culting too.
2019-03-29T15:38:42 < aandrew> did you make this schematic enh?
2019-03-29T15:38:55 < enh> I made it based on many datasheets.
2019-03-29T15:38:57 < enh> https://oshpark.com/shared_projects/Rdea4ZuY
2019-03-29T15:39:03 < karlp> "I2c_SMBA?" ?!
2019-03-29T15:39:06 < enh> This is a module based on that board.
2019-03-29T15:39:32 < aandrew> enh: why did you alter the way you C17/C18?
2019-03-29T15:39:41 < aandrew> also why on earth did you put the bypass caps vertically on the page
2019-03-29T15:40:00 < enh> I'm taking notes. 
2019-03-29T15:40:19 < aandrew> I see you're trying to indicate that each power pair gets a cap but it's enough just to put text that says "caps should be across every power pair"
2019-03-29T15:40:34 < aandrew> the schematic drawn that way doesn't actually translate to layout in a meaningful way and adds confusion
2019-03-29T15:40:43 < enh> Ok.
2019-03-29T15:40:55 < enh> Sorry. I'm really ignorant on this matter.
2019-03-29T15:41:01 < karlp> it's ok
2019-03-29T15:41:13 < aandrew> also just because shit happens, I try to always put 100R on the UART pins; someone will *always* fuck up the order and that helps protect the MCU until you realize your mistake
2019-03-29T15:41:22 < Thorn> https://www.youtube.com/watch?v=wqQvwtzi8N8
2019-03-29T15:41:41 < aandrew> hey man you made a schematic and (sort of) asked for review. we're happy to help and you appear willing to accept constructive criticism. you're the best kind of newb :-)
2019-03-29T15:41:42 < enh> ok
2019-03-29T15:41:48 < karlp> why was it a 4 layer board?
2019-03-29T15:41:57 < aandrew> karlp: because 4L is best layer
2019-03-29T15:42:01  * karlp laughs
2019-03-29T15:42:18 < enh> This board is a template for modules.
2019-03-29T15:42:23 < enh> https://oshpark.com/shared_projects/Rdea4ZuY
2019-03-29T15:42:32 < enh> This is a IMU based on that, for example.
2019-03-29T15:42:42 < aandrew> also if you're bring UART or I2C or anything out to pins, it's nice (but not necessary) to include a ground in the header because those signals need a reference and it's nice to plonk on one connector to whatever you're connecting to instead of having this extra flywire 
2019-03-29T15:43:02 < aandrew> for more advanced, multi-voltage designs it's also nice to have a VDDIO on the header as well
2019-03-29T15:43:26 < aandrew> these are both just nice things; not required, but really ups the "wow this is a nice design" factor
2019-03-29T15:43:29 < enh> The uart is just for emergency debug. I would get the ground from othe connector
2019-03-29T15:43:54 < enh> other. Sorry.
2019-03-29T15:44:44 < enh> aandrew: VDDIO on which header?
2019-03-29T15:44:47 < aandrew> also recommend reverse voltage protection (just a mosfet) on the power input. again, ust one of those "ohfuck did I fry the board" moments that you can save someone from
2019-03-29T15:44:56 < karlp> is usart2 one of the bootloader capable uarts?
2019-03-29T15:45:09 < enh> Is it easy to understand that the man bus is on the right header and the programming bus on the lef one?
2019-03-29T15:45:19 < aandrew> enh: I was just saying that for off-board busses it's nice to have a ground (and VDDIO) so you only need ONE connection to whatever it is you're connecting to
2019-03-29T15:45:32 < enh> ok. understood
2019-03-29T15:45:35 < aandrew> "is this a 3.3V or 5V or 1.2V IO?" - VDDIO tells all
2019-03-29T15:45:44 < enh> ok
2019-03-29T15:45:49 < aandrew> what is the max vin of the LD39050?
2019-03-29T15:46:02 < enh> one moment
2019-03-29T15:46:31 < enh> 5.5v
2019-03-29T15:46:32 < aandrew> also does F303 like it when VBAT is floating (I think I connect to VDD) when not doing battery/low power stuff
2019-03-29T15:46:35 < aandrew> enh: wow that's tight
2019-03-29T15:46:47 < aandrew> I'd but a 5.1V zener and polyfuse on that
2019-03-29T15:46:47 < karlp> within spec for usb.
2019-03-29T15:46:56 < karlp> you have more expensive parts on your boards aandrew
2019-03-29T15:47:14 < aandrew> sure, but I don't think this board is a USB connected board
2019-03-29T15:47:14 < enh> There is a power supply module with the same form factor, which delivers 3.3V and 5V. 
2019-03-29T15:47:35 < karlp> so why the extra regulator then?
2019-03-29T15:48:03 < enh> karlp: Because someone might want to use it out of my system, as it is can based.
2019-03-29T15:48:12 < aandrew> you've got the room, I'd definitely break out all the STM32 I/O to headers. just DNP them but that way they're there if you need one
2019-03-29T15:48:32 < karlp> I think they're trying to make a minimal template file for others to use
2019-03-29T15:48:38 < aandrew> enh: if it's not meant to be married to that supply board I'd definitely try to protect VIN a little bit, especially since it's so close to its limit
2019-03-29T15:48:41 < enh> aandrew: BGA like would suffice?
2019-03-29T15:48:53 < karlp> hence also all the white space int he middle of the schematic
2019-03-29T15:48:54 < aandrew> BGA? no, pads rip off way too easy
2019-03-29T15:49:05 < enh> ok
2019-03-29T15:49:13 < aandrew> but 2mm or 0.050" headers are small and still easy to solder to
2019-03-29T15:49:21 < enh> yep, karlp. See this link with an aplication: https://oshpark.com/shared_projects/Rdea4ZuY
2019-03-29T15:50:06 < enh> aandrew: Can you send me a link with an example on how to protect the regulator?
2019-03-29T15:50:16 < enh> Sorry for my ignorance.
2019-03-29T15:50:19 < aandrew> enh: no worries
2019-03-29T15:50:28 < aandrew> 5.1V zener, cathode to 5V in, anode to ground
2019-03-29T15:50:51 < aandrew> zener conducts above its rating (+/- tolerance, check that so it doesn't conduct at/below 5V)
2019-03-29T15:51:00 < jadew> I sense a new round of protests in Romania
2019-03-29T15:51:21 < aandrew> then put a polyfuse in series with the 5V circuit so when the zener conducts the polyfuse will open up
2019-03-29T15:51:22 < jadew> could escalate
2019-03-29T15:51:24 < enh> I'll try to find it at mouser. I'm ordering most of the components fro there. MCUs from aliexpress
2019-03-29T15:51:37 < aandrew> there are lots of zeners
2019-03-29T15:51:49 < aandrew> and reverse-voltage protection with any p-channel mosfet
2019-03-29T15:52:11 < aandrew> drain to vin, source to zener/reg input, gate to ground
2019-03-29T15:52:28 < aandrew> the body diode should be forward biased if I got source/drain correct here
2019-03-29T15:52:54 < aandrew> the idea is that when power is applied with correct polarity, mosfet conducts, acts like it's just a low resistance bit of wire
2019-03-29T15:53:26 < aandrew> when reverse-voltage is applied, mosfet is off, body diode is reverse-biased and the smoke doesn't get let out of your regulator
2019-03-29T15:53:32 < enh> I'll be moving to another room and will be back online in a few minutes. Sorry for that.
2019-03-29T15:53:52 < aandrew> no worries, I'm procrastinating
2019-03-29T15:59:53 < englishman> work bought me a dope ass casio
2019-03-29T16:00:02 < englishman> fx-991ex
2019-03-29T16:00:15 < englishman> c l a s s w i z
2019-03-29T16:02:45 < enh> back
2019-03-29T16:05:10 < enh> aandrew: On one of the modules I have a ESP32-WROOM connected to USART2. But I still left the pads for debugging there. The 100ohm resistors would be only for the pads, or should I keep them on the ESP32 connection as well?
2019-03-29T16:08:54 < enh> aandrew: A polyfuse asks for a current. The PSU on 5V can deliver up to 3A peak, 1.8 continuous. Should the polyfuse be for 3A?
2019-03-29T16:09:12 < enh> Sorry for so many questions.
2019-03-29T16:11:10 < Thorn> enh: the polyfuse should be sized to match your load, not the PSU
2019-03-29T16:12:05 < Thorn> if you're using it to protect the load
2019-03-29T16:15:36 < enh> Than it should match 6 times a typical servo current.
2019-03-29T16:19:44 < enh> On RC groups they suggest one polyfuse per servo channel 
2019-03-29T16:20:31 < Thorn> are you powering servos from this board?
2019-03-29T16:23:13 < enh> Not exactly from this one. This is a template. But yes.
2019-03-29T16:25:01 < enh> http://s000.tinyupload.com/index.php?file_id=09971701588716547342
2019-03-29T16:25:13 < enh> From this schematic
2019-03-29T16:26:02 < enh> https://oshpark.com/shared_projects/q77vIlYs  and this board
2019-03-29T16:28:21 < enh> What should be the power dissipation of the 5.1V zener diode?
2019-03-29T16:31:29 < aandrew> polyfuse should be rated to protect the zener in this case
2019-03-29T16:31:45 < karlp> idealy neglibile unless you're screwing up and having it conducting partly in the normal case. (been there done that)
2019-03-29T16:32:04 < aandrew> enh: the zener ONLY conducts when too much voltage is supplied
2019-03-29T16:32:15 < enh> ok
2019-03-29T16:32:35 < enh> Thanks for that
2019-03-29T16:33:10 < aandrew> so it doesn't have to dissipate much, only enough to endure until the polyfuse opens
2019-03-29T16:33:15 < enh> So I should have a zener on the 3.3V input too, I guess.
2019-03-29T16:35:06 < aandrew> I'm confused
2019-03-29T16:35:15 < aandrew> is the regulator not taking 5V down to 3.3V?
2019-03-29T16:40:11 < enh> aandrew: Nope. Just taking 3.3V and making 3.0
2019-03-29T16:40:44 < enh> One of the modules based on this has many sensors that feed on 3.3V max
2019-03-29T16:40:58 < karlp> so your "upstream" bus has pins for both 5v in and 3v3 in, and you optionall use either or?
2019-03-29T16:41:32 < enh> The main feed is 3.3V. The 5V feed is for peripheral stuff. like servos.
2019-03-29T16:41:55 < enh> Or whatever.
2019-03-29T16:42:35 < enh> When you recommended breaking out SWO you meant JTDO- TRACESWO?
2019-03-29T16:42:49 < enh> Only JTAG uses it, right?
2019-03-29T16:44:52 < karlp> no, I meant swo :)
2019-03-29T16:45:12 < karlp> jtag uses it yes, but if you're using swd (/you should be) you can use that swo pin to get magicaly sexy trace goodness.
2019-03-29T16:46:02 < karlp> heh, a particular file has some syntax in it that hangs intellij.
2019-03-29T16:46:05 < karlp> nice one.
2019-03-29T16:46:51 < basker> hello guys... i wish use the ad7606 with the stm32 but i have trouble finding a library to use it
2019-03-29T16:46:58 < enh> This link has the modules drafted so far. http://s000.tinyupload.com/index.php?file_id=30250812201777646062
2019-03-29T16:47:07 < basker> i have two boards to do some tests... a nucleo-746 that i guess conflicts ethernet with FSMC...
2019-03-29T16:47:17 < basker> thus i could use SPI interface to communicate.
2019-03-29T16:47:33 < basker> looking some codes in the github, i liked the implementation of this library by xujunjie96
2019-03-29T16:47:40 < basker> https://github.com/xujunjie96/STM32F407-AD7606/blob/master/HARDWARE/AD7606/
2019-03-29T16:47:59 < enh> karlp: I found no SWO on the stm32f303cc datasheet, only JTDO- TRACESWO
2019-03-29T16:48:11 < basker> but, i think this will be very difficult to port to a sw4stm32 project
2019-03-29T16:48:40 < karlp> enh: yes, that pin.
2019-03-29T16:48:57 < enh> Thanks. Sorry for the bad understanding.
2019-03-29T16:49:07 < karlp> basker:what is so special about a sw4stm32 project that doesn't let you use some code?
2019-03-29T16:51:30 < basker> karlp, i'm confused about the defines on the header file
2019-03-29T16:52:03 < Laurenceb> https://www.youtube.com/watch?v=T1Lwe7XLxMI
2019-03-29T16:52:11 < karlp> it's just a spi device right?
2019-03-29T16:52:15 < karlp> what's the real concern?
2019-03-29T16:53:31 < karlp> oh, you can use it parallel to. awesome
2019-03-29T16:54:13 < basker> i don't need a high converion rate.. is about ease of implementation
2019-03-29T16:54:26 < basker> it's
2019-03-29T16:55:25 < enh> karlp and aandrew: One last question: if I got it right, I can protect the 3.3V and the 5V inputs using the zener diode and a polyfuse, so I do not need the 3.3V regulator on board and can rely on the power fed from the power supply board, or from whereever else?

2019-03-29T17:00:16 < karlp> enh:well, what was the regulator there for before?
2019-03-29T17:00:46 < enh> To prevent overvoltages on the peripheral sensors
2019-03-29T17:00:56 < enh> And on the MCU
2019-03-29T17:01:33 < enh> In case someone makes a mistake trying to feed a single module, or the PSU module gets crazy.
2019-03-29T17:02:00 < Thorn> with Vin mac = 5.5V there's not much protection lol
2019-03-29T17:02:45 < enh> makes sense now
2019-03-29T17:02:51 < Thorn> *max
2019-03-29T17:03:11 < Thorn> also a regulator doesn't protect from overvoltages, it "creates a power rail" to quote Louis Rossmann (lol again)

2019-03-29T17:04:51 < Thorn> if you actually want a protection circuit use a TVS + polyfuse for example
2019-03-29T17:05:46 < karlp> (so yes, if the regulator was yoru protection before, then yes, you can replace it with the tvs+polyfuse
2019-03-29T17:06:57 < enh> Total Ignorance: what is TV5?
2019-03-29T17:07:44 < BrainDamage> tvs diode

2019-03-29T20:38:04 < marble_visions> all, i've got a question. i've got an i2c peripheral driver with send/recv functions, that take an i2c struct as a param, and a driver for an i2c device that requires a send and receive functions to be provided in order to do i2c operations. to combine the two parts, in main.c i've got glue code that intercepts the send/receive from the i2c device, and calls send/receive from the i2c periph, but with the added context: https://pastebin.com/p4pBYyPm
2019-03-29T20:38:25 < marble_visions> this works well, but i'm wondering if i can somehow do away with the glue code
2019-03-29T20:42:41 < kakimir> ub|k: howe is i2c?
2019-03-29T20:46:38 < marble_visions> the linux kernel has some sort of organization around bus drivers and device drivers that are attached to these buses, i might have to check how they've solved the problem

2019-03-29T20:57:44 < f3r70rr35f> hello
2019-03-29T20:57:45 < f3r70rr35f> !
2019-03-29T20:58:11 < marble_visions> hi f3r70rr35f
2019-03-29T20:58:25 < f3r70rr35f> I got an issue ... Im doing some calcs on a stm32l082
2019-03-29T20:58:40 < f3r70rr35f> for most of the processing im using int16_t types
2019-03-29T20:58:56 < f3r70rr35f> but I need to calc some sqrt() and pow()s
2019-03-29T20:59:08 < f3r70rr35f> so im casting the int values to float
2019-03-29T20:59:24 < marble_visions> Cracki: if there's a way to keep the i2c_drv inside the device struct... but this seems like bad cohesion and heavy use of void * function pointers
2019-03-29T20:59:51 < f3r70rr35f> curiosly, from time to time these cals return a nan value (not sure why, Ive been trying to debug)
2019-03-29T21:00:15 < Cracki> are you sure the NaNs come _directly_ from casts?
2019-03-29T21:00:32 < f3r70rr35f> and, during this debugging, I added some `isnan(var)` test before printing ... and magically there are no more nans ...
2019-03-29T21:00:33 < Cracki> all int16 values fit inside a single precision float
2019-03-29T21:00:44 < Cracki> too much compiler optimization?
2019-03-29T21:00:47 < f3r70rr35f> Im not sure where they come frome
2019-03-29T21:01:00 < Cracki> run under debugger with data watchpoint?
2019-03-29T21:01:22 < Cracki> you can watch the exponent byte of the float for nan range
2019-03-29T21:02:41 < f3r70rr35f> the debugger only runs on windows, no?
2019-03-29T21:02:41 < Cracki> or almost... exponent is bit 30..23, so the highest byte includes sign, and seven bits of exponent
2019-03-29T21:02:45 < Cracki> no
2019-03-29T21:03:03 < Cracki> what debugger do you have
2019-03-29T21:03:23 < Cracki> stlink, jlink, some keil stuff?
2019-03-29T21:03:46 < f3r70rr35f> im working with the st-link v2 programmer and st-tunned eclipse
2019-03-29T21:03:55 < Cracki> stlink is just fine
2019-03-29T21:04:03 < f3r70rr35f> (on a debian machine)
2019-03-29T21:04:13 < Cracki> your nans might come from something after the cast
2019-03-29T21:04:52 < Cracki> OR you see nans only in the debugger because these variables have been optimized to only live in registers, not ram locations, and that might confuse the debugger
2019-03-29T21:05:43 < f3r70rr35f> im only printing them ...
2019-03-29T21:05:49 < f3r70rr35f> (im new to stm)
2019-03-29T21:07:28 < f3r70rr35f> https://paste.debian.net/1075245/
2019-03-29T21:07:34 < f3r70rr35f> that's the code excerpt
2019-03-29T21:08:26 < f3r70rr35f> at first I thought they were type overflows
2019-03-29T21:09:02 < f3r70rr35f> but discarded it with the prints
2019-03-29T21:10:18 < marble_visions> f3r70rr35f: so data_x/y/z is int16_t data[] ?
2019-03-29T21:10:23 < marble_visions> s/is/are/
2019-03-29T21:10:29 < f3r70rr35f> marble_visions: yes
2019-03-29T21:10:54 < f3r70rr35f> im working with the adxl345 sensor with full resolution, which returns 13 bits ...
2019-03-29T21:10:58 < Cracki> odd error. play with compiler optimizations, lower them
2019-03-29T21:11:10 < Cracki> aha!
2019-03-29T21:11:13 < Cracki> you do a pow
2019-03-29T21:11:36 < Cracki> still, shouldn't affect a float...
2019-03-29T21:11:42 < f3r70rr35f> yeah, thats why im casting the int to float, as pow and sqrt receives floats ...
2019-03-29T21:11:51 < marble_visions> f3r70rr35f: and rms_x/y/z are float as well?
2019-03-29T21:11:57 < f3r70rr35f> yeah
2019-03-29T21:12:00 < Cracki> cast would happen implicitly anyway
2019-03-29T21:12:16 < Cracki> doesn't hurt tho
2019-03-29T21:12:35 < f3r70rr35f> (i thought that, but preferred to leave them explicitly ..)
2019-03-29T21:12:37 < Cracki> unless something writes those variables (some interrupt handler?)
2019-03-29T21:13:05 < Cracki> (not implying a relation)
2019-03-29T21:13:28 < f3r70rr35f> as u can see, in the validations I do in the commented prints, I chechek each calc step and it won't fail ...
2019-03-29T21:13:56 < f3r70rr35f> im not using interrupts of any kind now ... just debuggin the sensor part ...

2019-03-29T21:14:20 < Cracki> so that last printf spits out "nan" but the ones above don't?
2019-03-29T21:14:35 < f3r70rr35f> that's right ...
2019-03-29T21:15:23 < Cracki> break up the last printf into parts
2019-03-29T21:15:40 < Cracki> it shouldn't make a difference but maybe it does
2019-03-29T21:15:44 < f3r70rr35f> actually ... if I uncomment the above prints ... all works smoothly ..
2019-03-29T21:16:17 < Cracki> deactivate, or activate?
2019-03-29T21:16:58 < Cracki> declare these variables "volatile float ...", see if that makes a difference
2019-03-29T21:17:02 < f3r70rr35f> with both prints activated ... everything is OK; with the below enabled only -> nananaans
2019-03-29T21:17:05 < Cracki> maybe you have a compiler bug
2019-03-29T21:17:27 < marble_visions> f3r70rr35f: the diff between the statements is that you do an additional division "/ KURTOSIS_MAX_SAMPLES"
2019-03-29T21:17:28 < Cracki> uh
2019-03-29T21:17:30 < f3r70rr35f> I'll try the volatile
2019-03-29T21:17:33 < Cracki> you know what...
2019-03-29T21:17:36 < marble_visions> maybe that blows up?
2019-03-29T21:17:39 < Cracki> remove the square brackets from that format string
2019-03-29T21:18:06 < Cracki> that division could be 0...
2019-03-29T21:18:09 < Cracki> good point

2019-03-29T21:22:38 < marble_visions> mawk: maybe the compiler takes care of this
2019-03-29T21:22:54 < mawk> if you ask for float it will be float calculations
2019-03-29T21:22:59 < mawk> so with reduced accuracy
2019-03-29T21:23:21 < mawk> double is the default floating point type, at least on x86 and stuff
2019-03-29T21:23:28 < mawk> 1.0 is double, 1.0f is float
2019-03-29T21:23:29 < marble_visions> oh i thought you're saying that he does not have access to float/double so what he's doing is impossible
2019-03-29T21:23:33 < Cracki> i doubt that's x86
2019-03-29T21:23:42 < mawk> ah yeah no
2019-03-29T21:23:47 < Cracki> let him use singles if he wants
2019-03-29T21:24:11 < Cracki> L0 has no FPU, so singles are certainly a little faster than doubles :P

2019-03-29T21:39:28 < jpa-> it could also be a broken printf() that then reads random stuff from stack
2019-03-29T21:39:50 < jpa-> it's quite common for random printf() implementations to be more or less broken for floats
2019-03-29T21:40:33 < jpa-> get gdb running, it will make your debugging a lot easier
2019-03-29T21:41:39 < f3r70rr35f> https://paste.debian.net/1075247/
2019-03-29T21:42:32 < f3r70rr35f> jpa-: yeah, Ill need to check that for sure ...
2019-03-29T21:42:56 < jpa-> you could try printing  isnan(foo) in the same printf
2019-03-29T21:43:02 < f3r70rr35f> now it fails even with the prints (at least a consistent behavior)
2019-03-29T21:43:29 < Cracki> may I suggest initializing rms_x and rms_y to some known value (line ~10)
2019-03-29T21:43:42 < Cracki> you did it for rms_z already
2019-03-29T21:43:59 < jpa-> yeah, that's a good point
2019-03-29T21:44:09 < jpa-> same for all the other lines
2019-03-29T21:45:36 < Cracki> the way you write those definitions suggests you expect "=0" to apply to all listed variables; it doesn't, it only applies the variable immediately preceeding. "operator precedence" is like "(foo), (bar=something), (baz), ...;"
2019-03-29T21:46:15 < f3r70rr35f> oooh ... !
2019-03-29T21:46:52 < Cracki> to illustrate: int foo, *bar, baz; // foo and baz are ints, bar is a pointer to int
2019-03-29T21:47:24 < Cracki> not related to your situation, but might be good to know

2019-03-29T21:56:07 < PaulFertser> f3r70rr35f: if you were running this function on PC you could use valgrind and it'll tell you about uninitialised value. But I think gcc would tell it statically too, are you sure you're using -Wall in your CFLAGS?
2019-03-29T21:56:46 < Cracki> PaulFertser, I wasn't sure if he watched his values from a debugger or not, and some debuggers for some targets (at least some years ago) _do_ have an issue with variables that have been optimized to only reside in registers
2019-03-29T21:57:19 < PaulFertser> Cracki: gdb just tells "optimised out" if it can't show the variable.
2019-03-29T21:57:38 < Cracki> tbh those times I've experienced that, the debugger simply refused to show the value, instead of giving a value
2019-03-29T21:58:21 < Cracki> I second -Wall
2019-03-29T21:58:32 < f3r70rr35f> trully I havent tried the debugger yet ... newbie on this
2019-03-29T21:58:40 < f3r70rr35f> I'll dig it
2019-03-29T21:59:02 < Cracki> if you use an IDE, poke around in the project options, under "compiler", see if you can ask for "more warnings" or directly give it the -Wall flag
2019-03-29T21:59:11 < PaulFertser> f3r70rr35f: if you're a C programmer OCD will help a lot, breakpoints, watchpoints, stepping, even running functions interactively, all extremely useful.

2019-03-29T23:14:26 < marble_visions> also, what's happening with your signals after reset goes high, and before your cropped picture? because on the example that works, they pull reset up just before comm
2019-03-29T23:14:40 < ub|k> can't these people include makefiles in their example code?
2019-03-29T23:15:10 < marble_visions> you might be messing up the bus, some chips have a timeout if they detect whacky stuff

2019-03-29T23:17:16 < marble_visions> yeah but is there any activity after you pull up and before the i2c START condition?
2019-03-29T23:17:28 < marble_visions> since i can't see it from neither pics
2019-03-29T23:17:32 < ub|k> nope
2019-03-29T23:19:38 < marble_visions> right, and you're holding reset low for min of 1ms for the clocks to settle

2019-03-29T23:32:31 < ub|k> having a look at MCLK
2019-03-29T23:32:43 < marble_visions> so on page 16 of the cs refman you've got two things that have max times, tRC and tFC.. you might be failing one of those
2019-03-29T23:32:49 < marble_visions> page 17*
2019-03-29T23:33:22 < marble_visions> but if you're using the spi periph and not bitbanging this should not happen..

2019-03-29T23:34:57 < kakimir> it should not care
2019-03-29T23:35:23 < kakimir> but better turn that stone and see if clock is applied to MCLK before i2c comms
2019-03-29T23:35:43 < ub|k> no, it's not

2019-03-29T23:47:00 < kakimir> my laptop cpu is crimped to 9W
2019-03-29T23:47:08 < kakimir> it could do 15W
2019-03-29T23:47:50 < englishman> zyp, that's not a huge different, the non-EV kona here is about half price
2019-03-29T23:48:02 < englishman> so EVs are quite incentivized there
2019-03-29T23:48:04 < kakimir> but i'm pretty certain that power delivery chain to cpu has not been designed for 15W
2019-03-29T23:48:18 < zyp> englishman, well, yeah
2019-03-29T23:48:33 < englishman> i knew there were big incentives but not THAT much
2019-03-29T23:48:36 < zyp> EVs are still VAT and one-time-fee exempt
2019-03-29T23:48:56 < englishman> the rebates here will rise to $13k next year
2019-03-29T23:49:03 < zyp> VAT rate is 25%
2019-03-29T23:49:10 < englishman> but that still doesn't come close
2019-03-29T23:49:29 < englishman> and only counts for cars less than $45k so the kona is excluded
2019-03-29T23:50:04 < zyp> the one time fee (initial registration fee) depends on shit like emissions, size, power and shit, but I think it's typically in the same ballpark as the VAT
2019-03-29T23:50:33 < zyp> so I guess fees can add 50% or so overall
2019-03-29T23:56:17 < zyp> apparently that fee is 76k for the kona
2019-03-29T23:56:35 < englishman> 8700usd
2019-03-29T23:56:39 < englishman> not nothing
2019-03-29T23:57:44 < zyp> hmm
2019-03-29T23:58:42 < zyp> so out of the 326k I mentioned earlier, 76k is registration fee, 50k is VAT, meaning the car itself is 200k
2019-03-29T23:59:02 < zyp> compared to the kona electric that's 336k without either of those

--- Day changed Sat Mar 30 2019
2019-03-30T00:00:15 < englishman> how long until the tax incentives are gone due to popularity?
2019-03-30T00:01:34 < zyp> hmm, let's see
2019-03-30T00:01:35 < kakimir> norway can afford it
2019-03-30T00:02:12 < zyp> originally I believe the benefits were supposed to last until 50k EVs or 2017, whichever came first
2019-03-30T00:02:30 < zyp> I think 50k EVs were passed in 2015
2019-03-30T00:03:08 < zyp> and then it was renewed until the end of 2020
2019-03-30T00:04:52 < zyp> and apparently the sitting government have declared that they will keep those exempts for the period
2019-03-30T00:05:14 < zyp> IIRC next election is in the end of 2021
2019-03-30T00:05:34 < zyp> so I don't foresee it changing anytime soon
2019-03-30T00:06:20 < englishman> cool
2019-03-30T00:07:00 < englishman> if i can sell this dicknplace shit i think i'll buy an airplane

2019-03-30T14:24:51 < Steffanx> likes it.
2019-03-30T14:48:02 < Sadale> dongs, I'm not :(
2019-03-30T14:48:16 < Sadale> Steffanx, lol thanks xD
2019-03-30T14:48:25 < Sadale> dongs, ok. I'm insane. I don't care.
2019-03-30T14:48:54 < Sadale> Steffanx, anyway I think the game now breaks on newgrounds.
2019-03-30T14:49:06 < Sadale> Steffanx, here's the new link to play it: https://sadalenet.github.io/poopie/
2019-03-30T14:49:37 < Steffanx> it seemed to work Sadale
2019-03-30T14:49:41 < kakimir> I win
2019-03-30T14:49:59 < Sadale> Steffanx, oh. good for you. Perhaps it has something to do with browser settings
2019-03-30T14:50:14 < kakimir> that was quite addictive
2019-03-30T14:50:30 < Sadale> Thanks. In fact it's the game that I love the most out of all games that I made :3
2019-03-30T14:51:15 < Sadale> I found that a fun game isn't about how much efforts you've put into. It's about the game. The game itself. I completed making this game with, I guess just a week or two. :3
2019-03-30T14:51:16 < Steffanx> it needs a version 2.0
2019-03-30T14:51:20 < Steffanx> better graphics.
2019-03-30T14:51:28 < Sadale> lol I've thought about that. Never got the time to make one tho.
2019-03-30T14:51:38 < Sadale> Perhaps this time the boss is hilter? xD
2019-03-30T14:51:51 < Steffanx> nah

2019-03-30T15:25:05 < Steffanx> is it gamedev?
2019-03-30T15:28:11 < Sadale> Nope.
2019-03-30T15:28:15 < Sadale> gamedev isn't fun.
2019-03-30T15:28:24 < Sadale> And I'm not sure how well it pays.
2019-03-30T15:28:45 < Steffanx> so webdev it is?
2019-03-30T15:29:07 < Sadale> Nope. In fact I start my new job next Monday.
2019-03-30T15:29:33 < Sadale> I suppose it's mostly about embedded programming. The job title just said software engineer.
2019-03-30T15:29:59 < Sadale> It's about development of a special kind of router. It has embedded programming, backend dev and frontend dev. I suppose I'd be mainly responsible for the firmware.
2019-03-30T15:30:15 < Sadale> I'm not sure if I'd get assigned to do backend or frontend
2019-03-30T15:31:11 < Sadale> But I'd definitely get assigned to work on the firmware
2019-03-30T15:31:16 < Steffanx> backdoor it will be? :P
2019-03-30T15:31:28 < Sadale> lol I guess I could put one into the firmware :P
2019-03-30T15:31:31 < Sadale> That gotta be fun
2019-03-30T15:34:05 < Sadale> Guess what's my previous job. I resigned after working for it for a short while. :P
2019-03-30T15:34:24 < Sadale> In fact it was a nice job. But the new job offer is having far better compensation.
2019-03-30T15:34:27 < Sadale> That's why the switch.
2019-03-30T15:34:44 < Sadale> Anyway guess what sort of company I worked for in the job position that I've just resigned from :P

2019-03-30T15:39:53 < dongs> i was thinking more those shitty privacy router dickstaters

2019-03-30T15:40:11 < Sadale> dongs, it ain't a startup.

2019-03-30T15:40:27 < dongs> haha
2019-03-30T15:40:32 < Sadale> Anyway the previous company that I worked for is this one: https://sampsonstore.com/
2019-03-30T15:40:45 < Sadale> It's just awesome. I love the company culture.
2019-03-30T15:40:45 < englishman> dongtech
2019-03-30T15:40:54 < dongs> they literalyl sell dongs there
2019-03-30T15:41:02 < Sadale> The compensation they're offering is good. But the new offer is far better.
2019-03-30T15:42:10 < Sadale> Before working for this webstore, I freelanced for a while. And before that, I worked for a thermostat R&D company.
2019-03-30T15:42:12 < dongs> but you will need toi use lunix\
2019-03-30T15:42:40 < Sadale> By switching from that thermostats company to the latest job offer I have, I got a 60% salary raise. :3
2019-03-30T15:42:49 < Sadale> It's totally worth the switch. :3

2019-03-30T19:35:57 < PaulFertser> Example of duckduckgo vs. google: I ask "michelin pilot street pilot sporty" and the third link on DDG is "New rear tyre: Michelin Pilot Sporty or Street?" topic on forums, and I want to read just that. On Google I do not see that link on the first page at all.
2019-03-30T19:42:33 < Steffanx> i would have googled "michelin pilot street vs pilot sporty" or something :P
2019-03-30T19:42:50 < Steffanx> Result: hit # 2 or 1 :P
2019-03-30T19:45:40 < PaulFertser> But why google gives me plenty of links where either "sporty" or "street" are not present (or too far away) with my query?
2019-03-30T19:46:23 < Steffanx> it defaults to dutch here so.. its an unfair comparision.
2019-03-30T19:46:53 < Steffanx> im not sure why it does that though P
2019-03-30T19:46:59 < Steffanx> since i ask in english
2019-03-30T19:56:20 < zyp> were planning on renting a concrete mixer, but the logistics around that turned out to be too much bother, so I just bought a cheap one
2019-03-30T19:56:48 < zyp> also bought some bags of concrete: https://bin.jvnv.net/file/jlrLk.jpg
2019-03-30T19:58:03 < zyp> my car's only rated for 395kg payload, so I had to make two trips to bring it all home :p

2019-03-30T19:59:34 < zyp> it's not pure cement, it's dry concrete
2019-03-30T19:59:39 < zyp> i.e. cement premixed with sand
2019-03-30T20:00:02 < Cracki> yay shake and bake
2019-03-30T20:00:04 < zyp> so yes, I'm only gonna mix it with water
2019-03-30T20:01:46 < zyp> it costs a bit more than what cement and sand does separately, if you ignore the logistics cost

2019-03-30T20:03:21 < zyp> but it's not like I'd want to just shovel sand into my car, and the cost of renting something else to bring a load of sand home would be too much to make it worth it
2019-03-30T20:03:28 < Cracki> ;)
2019-03-30T20:04:19 < Cracki> so... you didn't have that delivered?
2019-03-30T20:04:36 < zyp> no, store is five minutes away so I just made two trips
2019-03-30T20:04:53 < Cracki> oh, makes sense
2019-03-30T20:07:50 < zyp> hmm
2019-03-30T20:08:10 < Cracki> when I saw those 25kg bags piled up I had to think back to a customer of a customer... they make and sell phosphates (in bags. their workers had to move truckloads worth of bags all day, individually, so now they have a suction robot to do the palletizing
2019-03-30T20:08:22 < zyp> hehe
2019-03-30T20:08:28 < zyp> hmm
2019-03-30T20:09:06 < zyp> so that's 750 kg, paid around 1200 NOK for the lot
2019-03-30T20:09:15 < zyp> I figure sand makes up about 5-600kg of it
2019-03-30T20:09:30 < zyp> local sand place wants 81 NOK per ton
2019-03-30T20:10:44 < Cracki> doesn't sound worth the time really

2019-03-30T20:11:29 < zyp> hmm
2019-03-30T20:12:40 < zyp> a ton of sand and cement for 400 NOK should make at least as much concrete as that stack, so the pre-mixed bags are about twice as expensive
2019-03-30T20:15:02 < zyp> sand shop charges 830 NOK for deliveries, so for larger amounts than this, it'd be worth it to have them come dump a pile outside my house
2019-03-30T20:15:13 < Cracki> you won't have to pay attention to the right mix, just dump it in and water it
2019-03-30T20:15:25 < zyp> yeah, that's also a benefit

2019-03-30T22:08:42 < Dako300> I'm trying to get SPI working on my STM32F4 board, and I have a test program on my computer that writes to and reads from the SPI line. Just reading from the line fires the HAL_SPI_RxCpltCallback (both with read() and with some Linux SPI ioctl). There is no data sent down the MOSI line (the STM32 is configured as a slave), so I'm thinking this RX callback is called whenever there is a clock signal 
2019-03-30T22:08:48 < Dako300> regardless of data coming in over RX. How would I make this so it only calls HAL_SPI_RxCpltCallback when data is received over the line? Thanks
2019-03-30T22:09:24 < Dako300> The SPI is configured on the STM32F4 board to be full duplex slave with DMA enabled

2019-03-30T22:23:34 < Dako300> Laurenceb_: nice
2019-03-30T22:23:46 < Dako300> you think you can help with an SPI DMA issue?
2019-03-30T22:24:15 < Dako300> I'm trying to get SPI working on my STM32F4 board, and I have a test program on my computer that writes to and reads from the SPI line. Just reading from the line fires the HAL_SPI_RxCpltCallback (both with read() and with some Linux SPI ioctl). There is no data sent down the MOSI line (the STM32 is configured as a slave), so I'm thinking this RX callback is called whenever there is a clock signal 
2019-03-30T22:24:21 < Dako300> regardless of data coming in over RX. How would I make this so it only calls HAL_SPI_RxCpltCallback when data is received over the line? The SPI is configured on the STM32F4 board to be full duplex slave with DMA enabled. I verified there is no data coming over the MOSI line with an oscilloscope. Thanks
2019-03-30T22:26:31 < Laurenceb_> sounds like you need to take a look at the master?!
2019-03-30T22:26:52 < Dako300> what should i look at?
2019-03-30T22:27:13 < Dako300> There is no data coming over the MOSI line but it still registers input as all zeroes
2019-03-30T22:27:47 < Laurenceb_> oh i see
2019-03-30T22:28:44 < Laurenceb_> tbh I havent used the hal for that
2019-03-30T22:29:02 < Dako300> did you use DMA without the HAL?
2019-03-30T22:29:58 < Laurenceb_> yes
2019-03-30T22:30:26 < Laurenceb_> it shouldnt fire off the interrupt without anything having happened
2019-03-30T22:30:44 < kakimir> hello lurencer
2019-03-30T22:30:50 < Dako300> it only fires when there is either an rx or tx, so i think its firing based on the master clock being active

2019-03-30T22:50:10 < Dako300> Laurenceb_: looking at the callback when it fires incorrectly the DMA2 Stream 2 IRQ is at the top of the call stack
2019-03-30T22:50:25 < Dako300> I'm not using DMA for TX, that's in polling

2019-03-30T23:00:41 < ub|k> kakimir, Cracki, marble_visions: I make a small C program based on libopencm3 that works OK (ACK received)
2019-03-30T23:04:36 < Dako300> Laurenceb_: if I configure it as a receive only slave the RxCpltCallback never stops firing, so there's always DMA activity
2019-03-30T23:10:09 < ub|k> how do I get registers such as SR1 in GDB?
2019-03-30T23:10:35 < karlp> x memorya_address
2019-03-30T23:11:13 < ub|k> karlp: and where can I find the memory address of my register? the reference manual says offset 0x14
2019-03-30T23:11:19 < ub|k> but offset relative to what?
2019-03-30T23:11:20 < karlp> compilgin with -ggdb3 can include more macros that might be enough
2019-03-30T23:11:42 < karlp> you can then do things like x SPI_SR1(SPI1) 
2019-03-30T23:11:58 < karlp> the reference manual also gives the base address in the memory map section
2019-03-30T23:12:06 < ub|k> oh ok, thanks
2019-03-30T23:13:22 < Dako300> the SPI line is supposed to be 500KHz if that helps

2019-03-31T00:56:46 < Steffanx> What kind of fence are you going place that it needs concrete?
2019-03-31T00:58:26 < zyp> dunno, haven't decided yet, probably something similar to the neighbor
2019-03-31T01:01:16 < zyp> I don't think it _needs_ concrete, but it needs to be mounted somehow and I figure concrete is a good way to do it
2019-03-31T01:05:18 < zyp> also, the reason I did this now is so that when they come and lay asphalt in my yard, they can lay it along the foundation, so it forms a nice edge

2019-03-31T06:54:07 < Ecco> it's ... an "str" instruction...

2019-03-31T13:35:52 < zyp> isn't it common knowledge that every other windows version is fucked up? :p
2019-03-31T13:40:59 < Steffanx> Thats why all we get is windows 10 and nothing but windows 10 now.
2019-03-31T13:41:33 < zyp> yeah
2019-03-31T13:41:55 < jpa-> you can still get ubuntu, and don't even have to wait for the "every other version"
2019-03-31T13:41:56 < zyp> maybe they're gonna do like macos now, so future versions will be 10.1, 10.2, 10.3 and so on
2019-03-31T13:45:11 < Steffanx> At least they're continueing the release of 1809 or something.
2019-03-31T13:45:18 < Steffanx> ms that is
2019-03-31T13:46:27 < Steffanx> So jpa-, it seems my stepper was rotating nicely, until something popped last night and im not sure what.
2019-03-31T13:46:49 < Steffanx> Some short in the 3.3V rail, but .. meh.
2019-03-31T13:51:24 < jpa-> measure which chip it is in?
2019-03-31T13:56:26 < Steffanx> How does one do that when its all connected together? Removing them one by one? I'd rather make a new board :P
2019-03-31T13:59:36 < jpa-> nah, feed 1A or so from lab supply, measure in lowest voltage range between two points
2019-03-31T13:59:50 < jpa-> you can see what way the current flows between those points and thus find where it goes
2019-03-31T14:00:29 < Steffanx> hm
2019-03-31T14:00:31 < jpa-> (normally mV range is enough, though if you have a big VDD plane then you need a more sensitive meter, µV or so)
2019-03-31T14:01:03 < Steffanx>  if you have a big VDD plane > awh :P
2019-03-31T14:01:42 < Steffanx> something might heat up a bit, perhaps i can detect that
2019-03-31T14:01:52 < Steffanx> i need an ir camera
2019-03-31T14:02:31 < jpa-> nah, if it is a real short-circuit (voltage drops close to 0V) you need a lot of current to get anything to heat up
2019-03-31T14:02:52 < Steffanx> its like 1 ohm
2019-03-31T14:02:52 < jpa-> at 1A, a typical via drops about 0.5mV, so depending on your multimeter you could see that
2019-03-31T14:07:03 < Steffanx> Anyway, will try. Ty
2019-03-31T14:30:29 < Steffanx> im not sure how long the stm32 will like it, since that's the part getting warmer and warmer :P
2019-03-31T14:31:52 < jpa-> well that sounds like the STM32 is short-circuited, unless it feeds 3.3V to somewhere else? (and to check that, you could hold it in reset)
2019-03-31T14:32:46 < Steffanx> hmm, sounds like you have much more experience with debuggin this kind of stuff :P
2019-03-31T14:34:01 < BrainDamage> you can also strobe the gpio individually to check which pin is shorted, use a binary search
2019-03-31T14:34:11 < Steffanx> but yeah, no reset luck.
2019-03-31T14:35:04 < kakimir> it's a while since I had short circuit last time
2019-03-31T14:35:20 < jpa-> yeah, well if STM32 is getting hot under reset, it sounds very much that it is broken
2019-03-31T14:35:25 < Steffanx> Doing a new board and not doing again what i did is perhaps a easier solution :P
2019-03-31T14:35:34 < jpa-> what did you do to break it?
2019-03-31T14:39:10 < Steffanx> Using the stepper motor as a generator to much. For some reason i did add protection for that :P
2019-03-31T14:39:40 < Steffanx> *too
2019-03-31T14:39:46 < Steffanx> damn, stop using ":P".
2019-03-31T14:45:28 < Steffanx> Im not sure why the stm32 would break from that, since its seperate power rails, but it must be that. Since it "popped" when i did that.
2019-03-31T14:46:56 < Steffanx> whops. i meant i didnt add protection for that
2019-03-31T14:47:08 < Steffanx> learn to english.
2019-03-31T14:52:01 < Steffanx> but then i dont know what the driver(s) do when they break and those are connected to the stm32

2019-03-31T15:20:02 < Mangy_Dog> it will have some bleeping too
2019-03-31T15:20:21 < Mangy_Dog> some sounds and the buttons will hopefully eventually be interactive setting different "scan" modes

2019-03-31T16:06:16 < Sadale> Well, I'll spam again about this tournament tomorrow :P
2019-03-31T16:06:30 < Sadale> Anyway this event is 100% real :P
2019-03-31T16:06:35 < Sadale> We've been holding it for years.
2019-03-31T16:06:56 < dongs> by "we" y ou mean you and your alt-personality right
2019-03-31T16:07:21 < Sadale> Nope. I try passing the host to other people every year.
2019-03-31T16:07:48 < Sadale> I don't succeed for every year tho. So I've hosted the event for two years out of four years.
2019-03-31T16:08:24 < Sadale> dongs, so you wanna host it next year? :P
2019-03-31T16:09:28 < Sadale> If you can do sysadmin or you can find someone else to do it for you, it's perfectly possible for you to host the next year's event :P
2019-03-31T16:09:45 < Sadale> The responsibility of the hoster is to get the website up and that's pretty much it is.

2019-03-31T16:26:29 < Sadale> mawk, The problem was that there was too many papers. It made those full scissors entries won. After that year, we've fixed the problem by not allowing more than 5 consecutives. For example, you can't throw six papers in a row.

2019-03-31T20:44:01 < kakimir> so?
2019-03-31T20:44:02 < ub|k> it turns out I was not setting the internal pull up resistor in the I2C pins
2019-03-31T20:44:04 < kakimir> tell
2019-03-31T20:44:10 < ub|k> and i was not setting them in open drain
2019-03-31T20:44:15 < ub|k> doing that solves the issue
2019-03-31T20:44:26 < kakimir> *rollseyes*
2019-03-31T20:45:32 < aandrew> LOL
2019-03-31T20:45:35 < aandrew> rookie mistakes
2019-03-31T20:45:39 < kakimir> doesn't the board have propper pullups?
2019-03-31T20:45:59 < aandrew> glad you solved it. I don't rely on internal pullups (it also gives a nice place to probe) but the OD thing would kill it dead, yes
2019-03-31T20:46:02 < Cracki> internal pullups don't do shit, they aren't meant for i2c, use proper external ones
2019-03-31T20:46:20 < kakimir> I bet there is external ones
2019-03-31T20:46:23 < aandrew> depending on the chip the pullups are also probably limiting your max i2c speed quite badly
2019-03-31T20:46:30 < Cracki> there must be if that's a devboard
2019-03-31T20:46:40 < ub|k> (it's a devboard)
2019-03-31T20:46:54 < aandrew> I've seen some right shit dev boards
2019-03-31T20:47:12 < kakimir> setting internal pullups should not have no effect if you have external ones
2019-03-31T20:47:13 < aandrew> I wonder if this was also englishman's i2c problem :-)
2019-03-31T20:47:50 < Cracki> what did you set them to, if not open drain?
2019-03-31T20:48:09 < aandrew> probably had them push-pull
2019-03-31T20:48:14 < kakimir> alternate function at least but
2019-03-31T20:48:21 < Cracki> yeh but why set them to pushpull
2019-03-31T20:48:32 < kakimir> if he didn't know any better
2019-03-31T20:48:33 < aandrew> although I'm kind of surprised that AF didn't automatically OD them
2019-03-31T20:48:48 < Cracki> I'm sure every example, every reference manual, ... talks about open drain right in the i2c chapter
2019-03-31T20:48:51 < Cracki> same
2019-03-31T20:48:54 < aandrew> Laurenceb_: aren't you supposed to be pasting brexit mems?

2019-03-31T20:49:15 < Cracki> I would be surprised if nobody mentioned open drain in here either
2019-03-31T20:49:18 < Laurenceb_> memmies
2019-03-31T20:49:32 < kakimir> I was about to say that another thing causing nack can be something actually driving line up
2019-03-31T20:49:35 < ub|k> ok, i don't recall anyone mentioning open drain
2019-03-31T20:49:45 < kakimir> like pushpull
2019-03-31T20:49:50 < ub|k> but anyway, i eventually found out what was wrong
2019-03-31T20:49:58 < aandrew> if brexit actually occurs I truly hope that the next gov who brings it back ends up having ot adopt the euro and all the other special features that the UK had disappear
2019-03-31T20:50:17 < kakimir> when brexit happens
2019-03-31T20:50:23 < kakimir> can I visit lurencer
2019-03-31T20:50:29 < aandrew> ub|k: we all make stupid mistakes and we bust each other's balls about it for years afterward, so prepare
2019-03-31T20:50:34 < ub|k> anyway, i confirm that removing the internal pull-up is OK
2019-03-31T20:50:38 < aandrew> kakimir: only with a visa
2019-03-31T20:50:38 < ub|k> aandrew: LOL
2019-03-31T20:51:14 < kakimir> ub|k: if you had oscilloscope
2019-03-31T20:51:36 < ub|k> kakimir: i do
2019-03-31T20:51:42 < kakimir> you could probs see open collector of slave and pushpull of mcu fighting
2019-03-31T20:51:51 < ub|k> ok
2019-03-31T20:51:52 < kakimir> creating this small step
2019-03-31T20:52:07 < ub|k> well, then I would have to know how to interpret it
2019-03-31T20:53:03 < kakimir> if you have like this step in the voltage where it goes a bit down but is still high
2019-03-31T20:53:08 < aandrew> but you would have pasted the pic saying WTF this is a digital signal, why do I see steps in it?!
2019-03-31T20:53:14 < aandrew> and we would have been able to tell you very quickly

2019-03-31T22:19:39 < Steffanx> Facebook > fake
2019-03-31T22:38:10 < kakimir> I mean
2019-03-31T22:38:40 < kakimir> I went once to some old summer house that was in middle of forrest
2019-03-31T22:39:12 < englishman> aandrew: what i2c problem was that?
2019-03-31T22:40:42 < aandrew> I thought you were moaning about some msp430 i2c issue
2019-03-31T22:41:14 < Steffanx> "I thought you were moaning about msp430", fix it for you :P
2019-03-31T22:41:26 < Steffanx> *fixed. damnit.
2019-03-31T22:41:44 < kakimir> there was this clock in a jar behind a window
2019-03-31T22:41:59 < kakimir> and some random stuff
2019-03-31T22:42:03 < kakimir> in the jar
2019-03-31T22:42:14 < kakimir> clock was still running
2019-03-31T22:42:16 < Steffanx> Was it one of those kakimir dreams?
2019-03-31T22:42:43 < kakimir> i could not tell
2019-03-31T22:43:08 < Steffanx> Hows the heart today?
2019-03-31T22:43:17 < kakimir> good
2019-03-31T22:43:28 < Steffanx> Do you have another scar now?
2019-03-31T22:43:37 < zyp> are you heartless?
2019-03-31T22:43:42 < kakimir> indeed
2019-03-31T22:43:56 < Steffanx> No, i love you zyp.
2019-03-31T22:44:05 < zyp> <3
2019-03-31T22:45:39 < kakimir> anyone played with simple camera interfaces?
2019-03-31T22:46:52 < zyp> simple how?
2019-03-31T22:47:25 < kakimir> simple to use
2019-03-31T22:47:43 < kakimir> whatever some cheap camera modules could use
2019-03-31T22:48:30 < zyp> in what sense do you mean interface? are you thinking about the actual connection/protocol?
2019-03-31T22:48:46 < kakimir> yes
2019-03-31T22:48:59 < kakimir> something I can throw to mcu or fpga
2019-03-31T22:49:04 < zyp> aren't they all just a parallel data bus with pixel clock, hsync or vsync?
2019-03-31T22:49:11 < zyp> s/or/and/
2019-03-31T22:49:30 < zyp> feed it to e.g. DCMI
2019-03-31T22:49:43 < kakimir> what is like ultimatelly cheapest chip
2019-03-31T22:49:58 < kakimir> that would have such camera interface
2019-03-31T22:50:02 < zyp> dunno, I've seen those OV-whatever are common
2019-03-31T22:50:10 < kakimir> OV?
2019-03-31T22:50:22 < zyp> I also routed some camera stuff at $oldjob, but I don't remember what part that was
2019-03-31T22:51:22 < zyp> I just got two prototype designs and got told to relayout them to fit together
2019-03-31T22:52:34 < zyp> OV is OmniVision, most common hit on google seems to be OV5670
2019-03-31T22:53:02 < zyp> hmm, but that's MIPI, not plain parallel
2019-03-31T22:54:02 < qyx> OV2640 is parallel
2019-03-31T22:54:06 < qyx> or OV5640 afaik
2019-03-31T22:54:18 < zyp> ah, OV2640 might be the one I'm thinking of
2019-03-31T22:54:21 < qyx> the newer ones are mipi@parallel
2019-03-31T22:54:26 < qyx> *&
2019-03-31T22:54:34 < qyx> but usually only MIPI is available on the connector
2019-03-31T22:54:38 < zyp> I think I got a camera module with the waveshare stm32f4 kit I bought
2019-03-31T22:55:00 < qyx> there is openmv or how is it caled
2019-03-31T22:55:03 < qyx> F4 + some cam
2019-03-31T22:55:43 < qyx> kakimir: probably some F412 or F413
2019-03-31T22:55:54 < qyx> or maybe F405/7
2019-03-31T22:56:04 < qyx> some L4 have DCMI too
2019-03-31T22:56:40 < zyp> openmv looks neat
2019-03-31T22:57:03 < zyp> https://openmv.io/collections/products/products/openmv-cam-h7
2019-03-31T22:57:12 < qyx> there is a question for ethernet pros: if 100Base-TX supports half-duplex & colision detection
2019-03-31T22:57:12 < zyp> H743 and a OV7725
2019-03-31T22:57:39 < qyx> AND it is possible to do a TX+/TX- -> RX+/RX- loopback
2019-03-31T22:57:55 < qyx> is it possible to short TX/RX pairs and use a bus topology with 100Base-TX?
2019-03-31T22:58:19 < zyp> I don't think so
2019-03-31T22:58:57 < qyx> I can't see any reason for not thinking so
2019-03-31T22:59:06 < qyx> but I haven't tried it yet
2019-03-31T22:59:11 < zyp> I believe the transmitter is always driving the link even when it's idle
2019-03-31T22:59:19 < qyx> mhm ok, good point
2019-03-31T23:00:41 < englishman> aandrew: yeah msp430 sucks dicks
2019-03-31T23:00:59 < zyp> I think each link is still composed of two unidirectional pipes no matter whether you call it half-duplex or not, colisions can only happen in repeaters/endpoints, not the link itself
2019-03-31T23:02:10 < zyp> both half-duplex and collision detection is mostly a remainder from shared media ethernet, doesn't make much sense for -TX
2019-03-31T23:04:03 < qyx> I know, I am just finding a suitable way of doing some high-speed comms on a passive backplane

2019-03-31T23:04:44 < zyp> bus comms, not point to point?
2019-03-31T23:04:56 < qyx> CAN-FD would be suitable if it was more available on stm32
2019-03-31T23:05:02 < qyx> yes, bus
2019-03-31T23:05:12 < qyx> ok, not necessarily
2019-03-31T23:05:25 < zyp> what throughput do you need?
2019-03-31T23:05:57 < qyx> > 10mbit/s shared, 100 is enough
2019-03-31T23:06:17 < qyx> it would be possible to use slot-to-slot p2p links and a sort of switching cards
2019-03-31T23:06:41 < zyp> are these off the shelf backplanes?
2019-03-31T23:07:01 < zyp> or do you control routing?
2019-03-31T23:07:08 < qyx> I can control routing
2019-03-31T23:07:22 < zyp> but it needs to be passive?
2019-03-31T23:07:25 < qyx> now I am using simple multidrop SPI
2019-03-31T23:07:40 < qyx> but without a backplane, it is just a stack of cards
2019-03-31T23:07:53 < qyx> there is MISO/MOSI, SCK, FRAME
2019-03-31T23:08:02 < qyx> it is more like microwire
2019-03-31T23:08:21 < qyx> frame is basically a CS signal
2019-03-31T23:08:53 < qyx> I would like it to be fully passive, it doesn't need to be
2019-03-31T23:09:21 < qyx> are you thinking of usb?
2019-03-31T23:09:38 < Cracki> usb, ethernet, pcie?
2019-03-31T23:09:39 < zyp> usb isn't shared
2019-03-31T23:09:49 < Cracki> each slot gets a port, all go to a switch
2019-03-31T23:09:50 < zyp> neither is pcie
2019-03-31T23:09:56 < zyp> yeah
2019-03-31T23:10:07 < Cracki> do you _really_ want shared medium
2019-03-31T23:10:15 < zyp> if you make the backplane, I'd just add some sort of hub/switch on it
2019-03-31T23:10:17 < qyx> yeah, I am asking because you are asking about it being passive
2019-03-31T23:10:20 < Cracki> shared medium makes it slow
2019-03-31T23:10:31 < zyp> either usb or ethernet, for stm32 stuff
2019-03-31T23:10:50 < qyx> zyp: the point is if the backplane fails, you have to disassemble the whole thing
2019-03-31T23:11:00 < zyp> ah
2019-03-31T23:11:07 < Cracki> also, does it need to be (hard) realtime? if yes, that's another constraint
2019-03-31T23:11:15 < qyx> no realtime
2019-03-31T23:11:24 < zyp> so a switch card lets the backplane be passive and is easy to replace
2019-03-31T23:12:31 < Cracki> high pin count on those connectors?
2019-03-31T23:12:52 < qyx> probably pci-e 1x connectors
2019-03-31T23:12:55 < qyx> 36pin or so
2019-03-31T23:13:13 < qyx> I am leaning towards the switching card solution too
2019-03-31T23:13:23 < zyp> sounds the most reasonable
2019-03-31T23:13:30 < qyx> together with a low-power and slower bus
2019-03-31T23:13:37 < qyx> like can or so
2019-03-31T23:13:47 < zyp> i2c would be the cheapest
2019-03-31T23:14:06 < qyx> if a device needs faster comms, you will have to put the card in the appropriate place
2019-03-31T23:14:12 < qyx> and use a switching card
