2018-03-01T00:00:12 < Steffanx> Isnt that java tool lunix compatible, englishman ?
2018-03-01T00:00:37 < englishman> ?
2018-03-01T00:00:40 < englishman> lunix has a ui?
2018-03-01T00:00:50 < Steffanx> Blaaa
2018-03-01T00:00:55 < Steffanx> Bla
2018-03-01T00:00:59 < Steffanx> Bzz
2018-03-01T00:01:26 < Steffanx> Better use that texane stuff then
2018-03-01T00:01:35 < englishman> yeah thats what i have been using
2018-03-01T00:01:39 < englishman> but someone said not to, it was old
2018-03-01T00:02:15 < Steffanx> Are you able to handle openocd?
2018-03-01T00:02:47 < englishman> i wouldnt phrase it that way necessairly
2018-03-01T00:03:19 < englishman> if i eventually figure out which --flash--this-shit commandline junk to type in, will it work?
2018-03-01T00:03:32 < Steffanx> Ofcourse
2018-03-01T00:03:48 < Steffanx> If not PEBKAC
2018-03-01T00:05:30 < Steffanx> If only openocd.org wasnt dead
2018-03-01T00:07:00 < Steffanx> Btw you have waffles now, you can stop the negativity be happy

2018-03-01T00:24:31 < Lux> is it normal that a pcba place only wants to deliver stuff if they ran it through a production test rig ?

2018-03-01T00:55:22 < upgrdman> if i need to use a regular mosfet to drive an inductive load, and if i dont want to use a flyback diode across the load, is a TVS between drain and source good enough? a TVS rated for a little less than Vds-breakdown.

2018-03-01T02:10:49 < kakimir> hey
2018-03-01T02:10:59 < kakimir> liquid metal is inside my shiet
2018-03-01T02:11:24 < kakimir> gains to single thread performance

2018-03-01T02:13:16 < kakimir> +2% to multi thread
2018-03-01T02:13:58 < kakimir> and full speed cpu clock mode "high performance mode" huge gains
2018-03-01T02:14:41 < kakimir> on silicon paste high performance mode actually ruins performance - absolute worst result of the tests
2018-03-01T02:15:14 < kakimir> on liquid metal the same mode gave the best results of the test
2018-03-01T02:15:16 < kakimir> tests
2018-03-01T02:16:15 < kakimir> better cooling makes all the dynamic clocking, throttling and shiet to work better
2018-03-01T02:20:10 < kakimir> all the smart shiet for these crapbook processors that give low base frequency that is doubled or tripled in boost mode
2018-03-01T02:25:12 < englishman> Lux: thanks il check it out. But I think also since this thing is just used to flash an attached stm32 2-3 times a year that il just shut off the orangepi and boot it up when I need it
2018-03-01T02:26:09 < englishman> Lux: and yes it can be standard to ask for that especially in a first run of something, it can save time later on if there is some error made serially
2018-03-01T02:27:12 < englishman> like for your project I would prefer to do flashing and etest here so I can 100% the boards before they leave and blame any future problems on shipping
2018-03-01T02:27:47 < englishman> or at least on someone other than me

2018-03-01T10:57:32 < zyp> hmm
2018-03-01T10:58:07 < zyp> got the design files for this ethernet shit
2018-03-01T10:58:48 < zyp> between the phy and the transformers, the signals are routed sanely as differential pairs
2018-03-01T10:58:58 < zyp> between the transformers and the connector, they're not
2018-03-01T11:00:52 < zyp> https://bin.jvnv.net/file/BeffU.png <- connector on the right side, transformer center and left, phy side on the top, connector side on the bottom
2018-03-01T11:05:08 < qyx> not much isolation clearance under the transformers
2018-03-01T11:05:12 < qyx> I would say none
2018-03-01T11:05:42 < zyp> that too, but that shouldn't affect signal integrity
2018-03-01T11:05:48 < qyx> besides that, cannot be the capacitive coupling a problem
2018-03-01T11:05:49 < qyx> ?
2018-03-01T11:06:23 < zyp> I guess, if there's enough of it
2018-03-01T11:07:39 < zyp> I wonder if it's worth lifting the end of a transformer and soldering an ethernet cable directly to it, to see if it makes a difference
2018-03-01T11:07:58 < qyx> also I would check the transformer
2018-03-01T11:08:09 < qyx> there are different types with/without cm chokes
2018-03-01T11:08:18 < qyx> if that makes any difference
2018-03-01T11:08:44 < zyp> this particular one does have cm chokes
2018-03-01T11:09:15 < qyx> idk actually what would happen if the transformer was mounted reversed
2018-03-01T11:09:23 < zyp> it's also one of the recommended options named in the phy datasheet
2018-03-01T11:09:28 < qyx> mhm
2018-03-01T11:09:48 < zyp> footprint is symmetric, so you'd just get the chokes on the wrong side
2018-03-01T11:10:04 < zyp> that happened on the first prototypes assembled
2018-03-01T11:10:05 < qyx> I know but how would that affect the functionality
2018-03-01T11:10:25 < zyp> probably doesn't make a difference
2018-03-01T11:10:32 < zyp> didn't seem to make a difference
2018-03-01T11:11:22 < qyx> because I am curious if the transformer driving is actually fully differential
2018-03-01T11:11:27 < qyx> when the common mode voltage is 3V3
2018-03-01T11:12:22 < zyp> ah, that's true
2018-03-01T11:12:34 < qyx> ss the choke could mess with that
2018-03-01T11:12:49 < zyp> I'm suspecting they each just have low side drivers
2018-03-01T11:12:54 < zyp> yeah, that makes sense

2018-03-01T11:23:07 < zyp> second board is designed to either run standalone, or with the first board inserted on the ethernet chain, depending on presence of 0R resistors
2018-03-01T11:23:37 < qyx> I don't like the gnd pour around the data lines
2018-03-01T11:23:40 < dongs> looks like scam350 gerber view

2018-03-01T11:38:46 < stvn> i want to sot23 my next op-amps
2018-03-01T11:43:51 < qyx> Tiny but mighty
2018-03-01T11:43:54 < qyx> zyp: ah
2018-03-01T11:44:04 < stvn> :3
2018-03-01T11:55:38 < zyp> haha, fuck this shit
2018-03-01T11:55:54 < stvn> yeh
2018-03-01T11:56:29 < zyp> I lifted one end of the transformer leaving only center taps connected to the board, then soldered cat5 directly to the legs of the transformer
2018-03-01T11:57:03 < zyp> other port links up perfectly now, but this one doesn't wanna link up at all
2018-03-01T11:57:29 < stvn> the best chopperless op-amp for low Vos
2018-03-01T12:00:26 < qyx> so whats the conclusion?
2018-03-01T12:00:29 < stvn> OP07D
2018-03-01T12:00:57 < qyx> speaking of transformers, I am going to abuse some
2018-03-01T12:01:08 < stvn> why?
2018-03-01T12:01:16 < qyx> because they are standard
2018-03-01T12:01:20 < stvn> :o
2018-03-01T12:02:31 < qyx> 7.5V stepup, dual low side mosfet driver, ethernet transformer and I get nice 30Vp-p out
2018-03-01T12:02:34 < qyx> ground referenced
2018-03-01T12:02:46 < qyx> hopefully

2018-03-01T12:06:33 < stvn> wtf
2018-03-01T12:06:44 < dongs> your pumping link
2018-03-01T12:07:39 < stvn> ah yeah
2018-03-01T12:08:00 < stvn> got that shit off instagram mate
2018-03-01T12:08:04 < stvn> jk
2018-03-01T12:11:21 < zyp> link eventually came up
2018-03-01T12:11:27 < zyp> https://bin.jvnv.net/file/uqm0t.jpg https://bin.jvnv.net/file/fRAqT.jpg
2018-03-01T12:12:30 < qyx> the second one is a bit retarded
2018-03-01T12:12:47 < zyp> I wonder which is tx and which is rx
2018-03-01T12:13:04 < stvn> i like your oscilloscope
2018-03-01T12:13:41 < zyp> stvn, it's some 40 MHz shit I picked up ten years ago
2018-03-01T12:14:02 < zyp> found out the other day that it has a hidden menu where I can select which model it is, so I switched it to the 100MHz model
2018-03-01T12:14:10 < stvn> as we all did
2018-03-01T12:14:13 < zyp> but still, these are 125MHz signals
2018-03-01T12:14:15 < stvn> surprised you never knew!!
2018-03-01T12:14:38 < stvn> back in the day i got my 50mhz model for ~$700aud
2018-03-01T12:14:49 < stvn> this was before eevflog was pumping i t
2018-03-01T12:14:52 < zyp> stvn, DS1052E?
2018-03-01T12:14:56 < stvn> yes
2018-03-01T12:15:02 < zyp> yeah, mine is older
2018-03-01T12:15:27 < zyp> this is a DS1042C
2018-03-01T12:16:03 < zyp> I've known about the firmware hack for DS1052E since forever, but that didn't apply to my scope
2018-03-01T12:16:11 < stvn> ah
2018-03-01T12:17:37 < stvn> and the audiotwits don't like it cause it doesn't look as pretty as the cathode ray oscilloscope trace
2018-03-01T12:18:09 < dongs> whats at 125mhz
2018-03-01T12:18:11 < stvn> like at the time my boss thought it was broken
2018-03-01T12:18:14 < dongs> ethernet or someshit?
2018-03-01T12:18:19 < zyp> 100base-tx
2018-03-01T12:19:38 < zyp> hmm, the nice looking one is the rx line, the messier looking one is the tx line
2018-03-01T12:19:46 < zyp> question is whether it's in MDI-X mode
2018-03-01T12:19:53 < qyx> I though they were two ports
2018-03-01T12:20:09 < zyp> same port
2018-03-01T12:20:15 < qyx> and now both are working?
2018-03-01T12:20:27 < zyp> yeah, it eventually linked up
2018-03-01T12:20:34 < qyx> interesting
2018-03-01T12:20:42 < dongs> F427s were shipped to me to finish my last weeks cockup
2018-03-01T12:20:49 < qyx> so the problem lies betqeen the transformer and the connector
2018-03-01T12:21:07 < zyp> how so?
2018-03-01T12:21:12 < qyx> or not?
2018-03-01T12:21:32 < dongs> is IPA conductive?
2018-03-01T12:21:32 < zyp> this is the port with cable soldered directly to transformer
2018-03-01T12:24:03 < zyp> qyx, wanna bet which trace is actually tx and which trace is actually rx?
2018-03-01T12:24:07 < stvn> i'd drink it
2018-03-01T12:25:33 < qyx> zyp: the nice one is tx!
2018-03-01T12:26:07 < zyp> no, chip says it's in MDI mode, so that's rx
2018-03-01T12:26:22 < dongs> is it not working?
2018-03-01T12:26:29 < zyp> i.e. tx is the one with the highest amplitude
2018-03-01T12:26:42 < qyx> so your tx is not looking good
2018-03-01T12:26:44 < zyp> dongs, that would have been easier
2018-03-01T12:26:48 < qyx> rx is from a switch?
2018-03-01T12:26:54 < zyp> the problem is that it's not always working
2018-03-01T12:26:59 < dongs> oh
2018-03-01T12:27:02 < dongs> shitty.
2018-03-01T12:27:18 < zyp> sometimes it doesn't want to link up, sometimes data gets corrupted, sometimes it works 100%
2018-03-01T12:27:28 < dongs> corrupted data is pretty bad
2018-03-01T12:27:36 < dongs> this is not ll boards righg
2018-03-01T12:27:59 < zyp> and I've been spending a week trying to figure out why, all I've managed to figure out so far is that a lot of things doesn't help
2018-03-01T12:28:11 < zyp> no, this is workstuff
2018-03-01T12:28:56 < zyp> qyx, it's from a profishark 1G in span mode
2018-03-01T12:28:56 < dongs> if I dont want to pay $250 for ATSAMA5D27-SOM1-EK1 what are my options?
2018-03-01T12:29:29 < stvn> murder people
2018-03-01T12:29:30 < zyp> buy a $40 SOM and make a breakout or deadbug it or something?
2018-03-01T12:29:35 < zyp> I've considered doing that
2018-03-01T12:29:41 < stvn> evaluation of what
2018-03-01T12:29:43 < qyx> is it a dimm som?
2018-03-01T12:29:51 < dongs> no its just a board
2018-03-01T12:30:02 < dongs> i only really need USB host on that thing
2018-03-01T12:30:04 < zyp> everything fast is on the SOM, so a 2L breakout should be fairly easy
2018-03-01T12:30:05 < dongs> and jtag
2018-03-01T12:30:48 < zyp> I've considered making one to throw in the DIN enclosure
2018-03-01T12:31:01 < dongs> to replace your EOL EDISON?
2018-03-01T12:31:08 < dongs> or wahtever the shit you were gonna use
2018-03-01T12:31:09 < qyx> nice one
2018-03-01T12:31:15 < qyx> I was considering the arietta thing
2018-03-01T12:31:18 < qyx> no, aria actually
2018-03-01T12:31:25 < zyp> dongs, yeah, kinda
2018-03-01T12:31:25 < qyx> pin compatible with some allwhiner stuff
2018-03-01T12:31:36 < qyx> corewind core-x20 or what
2018-03-01T12:31:49 < dongs> dongcore
2018-03-01T12:31:52 < stvn> why did shintel pull the plug on edison
2018-03-01T12:32:01 < dongs> because it was garbage mAKE:R shit
2018-03-01T12:32:04 < dongs> that nobody actually wanted
2018-03-01T12:32:10 < zyp> idk, tempted to just drop the whole linux thing and just put ethernet directly on the stm32
2018-03-01T12:32:23 < stvn> you're probably right mr dong
2018-03-01T12:32:39 < dongs> remaining edickson boards were shipped off to best korea olympics opening
2018-03-01T12:32:39 < karlp> I can sell you a two module linux gateway ifyou want? :)
2018-03-01T12:32:49 < dongs> then promptly incinerated
2018-03-01T12:32:50 < karlp> rs485, eth, wifi, sd card, openwrt sdk.
2018-03-01T12:33:11 < dongs> karlp: does it have usb host and documented baremetal bring up mode?
2018-03-01T12:33:39 < dongs> my shit doesnt need linsux
2018-03-01T12:34:01 < karlp> I wasn't talking to you :)
2018-03-01T12:34:08 < zyp> karlp, how much?
2018-03-01T12:34:13 < dongs>  < karlp> I can sell you a two module linux gateway
2018-03-01T12:34:13 < dongs> oh
2018-03-01T12:34:15 < dongs> i read this as
2018-03-01T12:34:15 < stvn> can somebody what is linux?
2018-03-01T12:34:16 < karlp> but yes, it does have usb host on an internal card edge
2018-03-01T12:34:19 < dongs> i can sell you two a module ..
2018-03-01T12:34:29 < dongs> as in talking to me/zyp
2018-03-01T12:34:38 < karlp> zyp: ~350 euros for singles
2018-03-01T12:34:42 < stvn> i read it as: your mum was good, your dad was better, but your dog was the best.
2018-03-01T12:34:53 < dongs> stvn, pump harder please.
2018-03-01T12:34:59 < zyp> karlp, not gonna happen :)
2018-03-01T12:35:01 < karlp> I know :)
2018-03-01T12:35:05 < stvn> i got a leak in the pump dude
2018-03-01T12:35:07 < karlp> but it's solved if you want it :)
2018-03-01T12:35:28 < karlp> I reckon we could sell a lot more at under 200 but not there yet.
2018-03-01T12:36:03 < dongs> which chink SoC is it using one of those AR9331 shits or hwatever/
2018-03-01T12:36:08 < zyp> where does all the money go? recouping engineering costs?
2018-03-01T12:36:19 < dongs> zyp, capitalism
2018-03-01T12:36:21 < karlp> various bullshits,
2018-03-01T12:36:33 < karlp> some of it is just volumes not being as high as might be nice.
2018-03-01T12:36:40 < stvn> coffee lake was alright
2018-03-01T12:36:45 < zyp> I don't imagine the BOM on an AR9331 based device being that muxh

2018-03-01T12:37:56 < dongs> gross.
2018-03-01T12:42:15 < stvn> fuck off
2018-03-01T12:42:26 < stvn> rust sounds fucking shit
2018-03-01T12:42:46 < dongs> favorite language of o6
2018-03-01T12:43:18 < dongs> operating system is a JavaScript interpreter built around the Lua runtime
2018-03-01T12:44:30 < stvn> fckingngf
2018-03-01T12:44:50 < karlp> where does it talk baout rust?
2018-03-01T12:45:25 < karlp> heh, mt7620, someone fell into the trap of buying the first gen
2018-03-01T12:45:28 < dongs> on what, shitsel.io?
2018-03-01T12:45:33 < karlp> hooray, you get the shit wifi!
2018-03-01T12:45:35 < dongs> the 'rust' tab on all the code samples
2018-03-01T12:45:41 < karlp> should have gotten mt7621 or later ;)
2018-03-01T12:45:55 < dongs> i dont even need wifi
2018-03-01T12:46:58 < dongs> what the fukchappened to retarduino yun
2018-03-01T12:48:52 < dongs> https://makezine.com/2018/02/27/faces-maker-faire-kuwait/
2018-03-01T12:53:09 < qyx> ok the fuk the ethernet transformer has too low inductance
2018-03-01T12:56:06 < dongs> well time to get the fuck outa here
2018-03-01T12:58:01 < zyp> https://bin.jvnv.net/file/Nlj5S.jpg <- here's how tx looks when it's sitting trying to get a link
2018-03-01T12:58:04 < zyp> rx still looks good
2018-03-01T12:58:31 < zyp> swapping MDI/MDI-X swaps which line looks good and which looks like shit
2018-03-01T13:00:11 < zyp> it's certainly TX looking like shit
2018-03-01T13:00:20 < zyp> I unplugged the other end and it's still doing that
2018-03-01T13:02:47 < karlp> replaced teh phy yet?
2018-03-01T13:02:59 < karlp> how many boards is this happening on?
2018-03-01T13:03:06 < zyp> all of them
2018-03-01T13:03:16 < karlp> oh, I thought you said some worked some didn't
2018-03-01T13:03:58 < zyp> that's the thing about sporadic problems, testing is not conclusive
2018-03-01T13:04:56 < zyp> I've got at least five boards here that I've both had successful link on both ports and issues with
2018-03-01T13:05:07 < zyp> so it's not a single defective phy
2018-03-01T13:05:49 < zyp> the ethernet chip is a ksz8893mql, three port switch with two phys and RMII to the MCU
2018-03-01T13:07:59 < qyx> I still don't get it
2018-03-01T13:08:06 < qyx> you lifted one transformer
2018-03-01T13:08:12 < qyx> and soldered directly to tp wires
2018-03-01T13:08:17 < qyx> and something started working
2018-03-01T13:08:22 < qyx> the other port?
2018-03-01T13:08:23 < zyp> no
2018-03-01T13:08:47 < qyx> so all is still half working
2018-03-01T13:09:10 < zyp> yes, soldering directly to transformer made no apparent difference
2018-03-01T13:09:33 < zyp> both ports are sometimes working

2018-03-01T14:49:26 < qyx> not like on gate drivers when disabling means actually forcing output low
2018-03-01T14:50:19 < qyx> something like 74*125, but for higher voltage

2018-03-01T17:21:28 < karlp> 8C and sunglasses.
2018-03-01T17:21:30 < karlp> super nice
2018-03-01T17:21:43 < karlp> not taking the studded tires off yet though
2018-03-01T17:26:38 < zyp> been like -10C here for the past few days
2018-03-01T17:26:51 < zyp> bunch of cars crashing and shit
2018-03-01T17:27:25 < zyp> apparently people in the south of norway don't learn how to drive
2018-03-01T17:29:00 < tomeaton17> my crappy front wheel drive is going to struggle lol
2018-03-01T17:29:16 < karlp> rwd isn't going to magically drive better on snow
2018-03-01T17:29:19 < zyp> https://www.nrk.no/sorlandet/fortsatt-vanskelig-pa-veiene-1.13939261 <- yesterday

2018-03-01T17:30:00 < zyp> tomeaton17, in my experience, RWD is crap for getting anywhere, particularly up hills
2018-03-01T17:30:11 < tomeaton17> yeah goof on my part
2018-03-01T17:30:27 < zyp> my old car was RWD, current is FWD
2018-03-01T17:31:34 < zyp> new car gets around anywhere, only way I've gotten it stuck so far is trying to drive through too deep snow and getting it hanging
2018-03-01T17:32:00 < zyp> old car used to struggle getting out of the parking lot because it was uphill
2018-03-01T17:33:29 < zyp> only thing I miss is being able to drive sideways, new car doesn't do that :(
2018-03-01T17:34:40 < Rob235> AWD on my old impreza was fun. more power on my TL is funner :)
2018-03-01T17:36:32 < karlp> "TL" ?

2018-03-01T20:57:53 < upgrdman> not me
2018-03-01T20:57:58 < upgrdman> but why? reduce glare?

2018-03-01T21:04:20 < upgrdman> got a bug report from someone using os x, but i haz no applez
2018-03-01T21:10:40 < perole> upgrdman: reduce reflections and possibly make chip markings easier to read
2018-03-01T21:11:16 < upgrdman> perole, ok. i've heard of people using adjustalbe light sources for that. but ya, maybe a polarizer would do nicely.

2018-03-01T21:22:15 < Steffanx> Any idea what going on with this stm8s003 yet?
2018-03-01T21:23:20 < Thorn> the source didn't think to ask :/
2018-03-01T21:24:20 < Steffanx> and it might be NRND there still is the 10 years Longevity Commitment
2018-03-01T21:24:30 < Thorn> and there's something called stm32g in the works
2018-03-01T21:24:43 < Steffanx> but that is a bit weird though "In case of significant volume decrease, technology or manufacturing changes, a switch to a comparable product, another technology or a different manufacturing facility could be decided by  STMicroelectronics "
2018-03-01T21:25:05 < Steffanx> so in reality its not really a commitment
2018-03-01T21:26:04 < Steffanx> stm32g looks almost like a typo Thorn
2018-03-01T21:26:26 < upgrdman> what does the g stand for

2018-03-01T21:35:08 < Steffanx> Ultrasauce: wtf is le dank memes?
2018-03-01T21:45:20 < Ultrasauce> Excuse me but are you a meme hater? Let me preface this by saying that I've been a memer since they first appeared on 4chan circa 2006 (ages ago in internet time). I remember refreshing /b/ all afternoon with the hope that someone would make a new meme. I was a memer back when Advice Dog was the only one and I still upvote every Advice Dog meme I see becasue of the fond rush of nostalgia it brings me. Nowadays, there are many thousand on livememe and
2018-03-01T21:45:20 < Ultrasauce> other meme websites. I was a memer back before memegenerator was created (the first meme website) and I had to make them with MS Powerpoint or Paint. Speaking of meme websites, I was one of the first submitters to memebase.com and still have one of the top accounts there despite having migrated to reddit nearly 2 years ago. It was on 4chan and memebase where I cut my teeth creating memes, way before I had a reddit account and way before/r/adviceanimals[1
2018-03-01T21:45:20 < Ultrasauce> ] was created in late 2010. Back before I could get any sort of points or even username recognition, I was creating memes as a clever and easily digestible way to reflect on society, relate some story to my audience, or just be funny. Do you remember rich raven? No? I do. You probably don't remember depression dog, crazy girlfriend praying mantis, introspective pug, or friendzone Johnny either. I remember all of them. In fact, you've never even submitted
2018-03-01T21:45:20 < Ultrasauce>  to /r/adviceanimals[2] . So please, respect my judgement regarding the direction of the subreddit and the integrity of posts I have held dear to my heart for nearly 7 years but you have no strong feelings for.
2018-03-01T21:50:42 < Steffanx> tldr; Ultrasauce :P
2018-03-01T21:51:09 < upgrdman> so i went to Apex Expo a couple days ago. it was really neat to see real pcb manufacturing stuff up close and in person. those automated flying probe machines look so fucking alien.
2018-03-01T21:51:43 < upgrdman> and Nikon has a super nice ct x-ray machine.
2018-03-01T21:51:59 < upgrdman> amaze focus and zoom

2018-03-01T22:52:26 < englishman> ?
2018-03-01T22:52:32 < englishman> never heard of it
2018-03-01T22:52:35 < upgrdman> super neat seeing a live CT-style x-ray of a pcb

2018-03-01T22:53:20 < upgrdman> ah
2018-03-01T22:53:55 < upgrdman> and nikon is currently the leader for AXI image quality. they bought the tube maker that does the best tubes for that
2018-03-01T22:54:12 < upgrdman> you can literally watch the machine zoom in to the bond wires of a BGA
2018-03-01T22:54:20 < upgrdman> and see the bond wire is clear detail
2018-03-01T22:54:30 < upgrdman> fuck i should have recorded it

2018-03-02T07:17:05 < dongs> You are using a STM32 device with a SPI who include a FIFO.
2018-03-02T07:17:05 < dongs> To be sure to not retrieve old data, please use "HAL_SPIEx_FlushRxFifo" function before call a "HAL_Receive" function. Thanks to this, the FIFO will be flushed (Rx side only), and you will retrieve correct data. (i.e. without shift).

2018-03-02T08:07:47 < dongs> ok, solved. the extra reads were due to DMA
2018-03-02T08:07:52 < dongs> dma writes
2018-03-02T08:08:00 < dongs> which would stuff the fifo
2018-03-02T08:08:13 < dongs> added an extra loop after reads, and not hitting the other shit anymore
2018-03-02T08:08:23 < dongs> er extra loop after DMA write to clear fifo, tehn done
2018-03-02T08:11:58 < dongs> 1210 47uF tant is 10c @ small qtys
2018-03-02T08:12:11 < dongs> 1206 is more expensive, around 22c or so
2018-03-02T08:12:23 < dongs> 10V
2018-03-02T08:14:43 < dongs> i dont do 50V shit

2018-03-02T10:01:16 < kakimir> can I just flash the chip fro mcuxpresso
2018-03-02T10:01:21 < kakimir> without debug session
2018-03-02T10:01:51 < kakimir> have you ever bricked a chip with user code?
2018-03-02T10:03:10 < kakimir> it's really gay you can not flash your chip but only with their propiertary link
2018-03-02T10:03:23 < kakimir> not via gdb session
2018-03-02T10:03:39 < kakimir> openocd session or such
2018-03-02T10:04:26 < dongs> your fault for chooosing gay chips
2018-03-02T10:04:49 < kakimir> and not using keil
2018-03-02T10:04:52 < dongs> correct.
2018-03-02T10:06:31 < qyx> mhm that st thing supports ipv6
2018-03-02T10:06:33 < kakimir> I knew.. I'm gay
2018-03-02T10:07:56 < Steffanx> kakimir: it can do that
2018-03-02T10:08:03 < kakimir> how?
2018-03-02T10:08:14 < kakimir> flash and verify
2018-03-02T10:08:16 < kakimir> only
2018-03-02T10:08:37 < Steffanx> There should be a Linkserver GUI programmer button
2018-03-02T10:09:25 < kakimir> what should I do with that?
2018-03-02T10:09:46 < Steffanx> Program.
2018-03-02T10:09:53 < kakimir> it supports only one probe
2018-03-02T10:10:19 < kakimir> doesn't it?
2018-03-02T10:10:36 < kakimir> correct
2018-03-02T10:10:54 < kakimir> so was the axf file actually elf with wrong name?

2018-03-02T10:13:33 < kakimir> I wonder if openocd flash verify will take axf file.. I see I had elf files in my openocd folder from time I had flash issues with lpc1517
2018-03-02T10:13:43 < dongs> axf is same as elf yeah
2018-03-02T10:16:51 < kakimir> weird thing another board isp answers just garbage
2018-03-02T10:17:03 < kakimir> this board isp doesn't answer anything
2018-03-02T10:17:21 < kakimir> but isp works because debugger connection is restored
2018-03-02T10:17:27 < kakimir> when pulled low
2018-03-02T10:17:36 < kakimir> +reset
2018-03-02T10:19:16 < kakimir> in both
2018-03-02T10:22:26 < Steffanx> So found the tool kakimir ?
2018-03-02T10:24:17 < kakimir> didn't I say
2018-03-02T10:24:36 < kakimir> it's half-gay
2018-03-02T10:24:53 < kakimir> openocd.org is down for a while now :]
2018-03-02T10:24:54 < Steffanx> I meant: does it work for you. You complained about probe support and then you lostme
2018-03-02T10:25:09 < kakimir> I don't have lpc-link II
2018-03-02T10:25:13 < kakimir> should I get one?
2018-03-02T10:25:20 < kakimir> looks like I should
2018-03-02T10:25:40 < Steffanx> Afaik it should work with any programmer supported by mcuxpresso
2018-03-02T10:25:45 < kakimir> nope
2018-03-02T10:25:54 < PaulFertser> kakimir: whole SF is down
2018-03-02T10:26:00 < kakimir> oh
2018-03-02T10:26:01 < PaulFertser> kakimir: why would you need openocd.org anyway?
2018-03-02T10:26:06 < kakimir> for how long?
2018-03-02T10:26:29 < kakimir> I just look from there some stuff
2018-03-02T10:26:36 < kakimir> I want to erase and verify erase
2018-03-02T10:26:44 < Steffanx> The docs are there too right PaulFertser ?
2018-03-02T10:26:53 < Steffanx> THAT part sucks arse
2018-03-02T10:27:21 < Steffanx> Why is sf down btw?
2018-03-02T10:27:27 < PaulFertser> Steffanx: man, OpenOCD comes with _online_ docs which means they are installed along with the binary to be read electronically on the same machine (i.e. locally).
2018-03-02T10:27:36 < kakimir> I don't remember when I was able to get to openocd.org last time
2018-03-02T10:27:47 < kakimir> there is no man in windows
2018-03-02T10:28:33 < PaulFertser> You can choose any Info browser you like. Also, I think windows packagers usually provide PDF render for that.
2018-03-02T10:29:21 < kakimir> I see
2018-03-02T10:29:49 < Steffanx> But i like to google PaulFertser :P

2018-03-02T10:42:13 < kakimir> oh
2018-03-02T10:42:45 < kakimir> does the command look okay for lpc1111 201?
2018-03-02T10:42:49 < kakimir> has one flash
2018-03-02T10:42:55 < kakimir> 2sectors

2018-03-02T10:43:01 < kakimir> 0 and 1
2018-03-02T10:43:20 < PaulFertser> kakimir: probably you need "init; ..." before that

2018-03-02T11:51:03 < Tectu_> that happens, Sir.
2018-03-02T11:51:11 < Tectu_> better be proud that you found it :)
2018-03-02T11:51:32 < zyp> yeah, after ruling out every single other thing it could be

2018-03-02T11:52:26 < dongs> this is why you use dongs asembly service

2018-03-02T11:57:18 < dongs> .dk probably sends to latvia
2018-03-02T11:57:26 < zyp> this is not even the first parts it happened on, we discovered they did the same on some of the vreg feedback resistors on the first protos
2018-03-02T11:57:47 < zyp> ethernet signal integrity is just harder to catch than totally wrong supply rail voltages

2018-03-02T11:58:55 < kakimir> Steffanx, does mcuexpresso create Release version automatically to run without debugger?
2018-03-02T11:58:58 < stvn> 'melbourne printed circuit' sends their shit to china and pretends it is made in au
2018-03-02T11:59:08 < kakimir> or set up the building options so
2018-03-02T11:59:10 < zyp> I scoped the signals on both, noticed amplitude was much lower on the working board
2018-03-02T11:59:57 < Steffanx> Do a release build for all projects kakimir
2018-03-02T12:00:03 < zyp> suspected drive strength first, but current ref resistor looked correct on both
2018-03-02T12:01:38 < kakimir> okay
2018-03-02T12:01:45 < kakimir> problem is with my debug session
2018-03-02T12:01:50 < kakimir> did just flash release

2018-03-02T12:03:29 < kakimir> is there any tricks I should try in debugger options?
2018-03-02T12:03:37 < kakimir> I think I have changed nothing since it worked
2018-03-02T12:04:11 < kakimir> should I change some init / reset options
2018-03-02T12:04:41 < kakimir> should I do some init; halt instead of halt
2018-03-02T12:05:16 < PaulFertser> kakimir: init just needed to go from configure stage to run stage where runtime commands are allowed.
2018-03-02T12:05:46 < kakimir> I wonder what they have programmed in flash from factory
2018-03-02T12:05:55 < kakimir> if it's not actually erased
2018-03-02T12:06:21 < kakimir> PaulFertser, I don't undestand
2018-03-02T12:06:33 < kakimir> just tell me if to try anything in debugger settings page or not
2018-03-02T12:06:51 < PaulFertser> kakimir: I can't understand what your actual problem is. What's not working?
2018-03-02T12:14:48 < kakimir> I flash release with openocd command - works fine
2018-03-02T12:15:07 < kakimir> then I switch debug build and press debug
2018-03-02T12:15:13 < kakimir> sigfaults
2018-03-02T12:15:36 < kakimir> thing is I got program in once with that
2018-03-02T12:15:41 < kakimir> or twice
2018-03-02T12:15:46 < kakimir> and debug session was working
2018-03-02T12:16:00 < PaulFertser> What segfaults?
2018-03-02T12:17:18 < kakimir> I don't know
2018-03-02T12:18:02 < kakimir> can I set breakpoint to reset isr?
2018-03-02T12:19:02 < PaulFertser> I mean is it openocd that segfaults? Or your target firmware?
2018-03-02T12:20:49 < kakimir> target
2018-03-02T12:20:53 < kakimir> hmm
2018-03-02T12:20:58 < kakimir> could optimization do it?
2018-03-02T12:21:21 < PaulFertser> Usually optimised buggy firmware crashes, not the other way round.
2018-03-02T12:21:27 < qyx> your code does it
2018-03-02T12:21:46 < kakimir> my code is essentially boilerplate with pin toggle
2018-03-02T12:22:16 < qyx> there are maybe some essential details
2018-03-02T12:22:34 < kakimir> just cmsis, clock config off from system_LPX11xx.c
2018-03-02T12:22:37 < kakimir> and toggle pins
2018-03-02T12:22:59 < kakimir> it runs with default settings
2018-03-02T12:23:57 < qyx> I am wondering how the hell is the internal pga resistor divider in the stm32 internal opamps connected
2018-03-02T12:24:13 < qyx> if it is tied to vssa then the opamp is useless
2018-03-02T12:24:36 < qyx> also I cannot find anything about setting the offset
2018-03-02T12:24:42 < qyx> offset calibration only
2018-03-02T12:27:04 < qyx> I mean setting the vcom
2018-03-02T12:27:49 < kakimir> it seems my compiler optimizes my delay function
2018-03-02T12:27:58 < kakimir> leds are blinking quite fast
2018-03-02T12:28:11 < kakimir> at about 1microsecond pulses
2018-03-02T12:29:10 < kakimir> did __attribute__((optimize("O0"))) to function definition
2018-03-02T12:29:56 < kakimir> no way it does 2000times loop of 5000 in 1microsecond

2018-03-02T16:18:46 < Rob235> how do you print threads well? do you have to offset the thread face to shrink it down a bit and scale the vagina piece?

2018-03-02T16:18:56 < Rob235> or should it work as is
2018-03-02T16:20:09 < Tectu> Rob235, that depends on how it was designed and on how well your printer is. Usually you just print it the way it is. I never had any problems except for with a thingiverse design but there the designer made it too tight in the model (literally no gap at all). But then again, I never worked with shitty printers
2018-03-02T16:20:51 < Rob235> ok because I thought you had to do the two things I mentioned but it was too loose. I'll try it as is next

2018-03-02T16:26:59 < Rob235> ok, maybe I should create some test prints of just threads to test out
2018-03-02T16:27:03 < Ultrasauce> yes
2018-03-02T16:27:18 < Rob235> instead of reprinting this whole piece, while not big at all, its mostly just the threads, its still wasteful

2018-03-02T18:22:04 < tomeaton17> Is it possible to have v grooves visualised in altium 3d view?
2018-03-02T18:26:33 < englishman> good question
2018-03-02T18:26:43 < englishman> i dont think so
2018-03-02T18:26:51 < englishman> ther are also different types of vgrooves
2018-03-02T18:27:06 < englishman> they can certainly appear as lines, but i doubt they will show in 3d
2018-03-02T18:27:39 < englishman> no i think you will have to deal with that wrt. your stackup and vgrooving at the fab stage
2018-03-02T18:28:05 < tomeaton17> Yeah. I was looking at getting my board produced with pcbway, their guidlines say for v groove separation make the space between the boards 0. I dont understand that
2018-03-02T18:28:39 < englishman> probably because they are allowed edge tolerances, and copper keepout tolerances
2018-03-02T18:29:45 < tomeaton17> yeah probably, will have to add a pullback rule
2018-03-02T18:45:16 < tomeaton17> they only specify a minimum spacing, 0.15mm. However the board outline tolerance is
2018-03-02T18:45:23 < tomeaton17> +-0.2mm

2018-03-03T00:48:45 < englishman> were you dreaming about mailing my cat to a hungry gypsy family
2018-03-03T00:51:57 < englishman> all i want is gay married couples to be free to protect their marijuana fields with fully automatic machine guns
2018-03-03T00:58:33 < PaulFertser> Aren't US democrats generally pro more gun control?
2018-03-03T01:01:37 < Steffanx> Haha how to get rid of superbia :d
2018-03-03T01:02:32 < PaulFertser> I wonder why people pay so much attention to topics that do not really affect their lives. Most people are not gay, so gay marriages are mostly irrelevant for them. Same about recreational drug use. Why is all that such a hot topic?
2018-03-03T01:02:51 < englishman> when society runs out of problems, it makes new ones
2018-03-03T01:03:21 < Steffanx> Hah. Thats exactly what happens in here indeed
2018-03-03T01:03:34 < PaulFertser> Duh, the US society has plenty of real problems.
2018-03-03T01:04:10 < BrainDamage> here being stm32 or your country?
2018-03-03T01:04:48 < Steffanx> Dutchland, BrainDamage
2018-03-03T01:05:29 < BrainDamage> your country is considerably less insane than mine on those topics
2018-03-03T01:06:45 < Steffanx> But we create new "problems" on a daily basis
2018-03-03T01:07:06 < Steffanx> They get hyped in the media and off we go
2018-03-03T01:07:21 < BrainDamage> PaulFertser: regarding marriages sometimes here people make an argument about economy, because married people receive special discounts on taxes from the state, as insane as that may sound
2018-03-03T01:07:38 < BrainDamage> so they mix their ideologies with economy, you can imagine how well that goes

2018-03-03T01:11:16 < PaulFertser> BrainDamage: do they imply that marriages are bad for the economy then?
2018-03-03T01:12:32 < BrainDamage> no, that the budget is tight and don't want to give money to more people, at the same time, they are recipient of those benefits, which means, they are just greedy
2018-03-03T01:16:04 < PaulFertser> The state supports family for a reason, right? If it plays against the country's interest, why doing that at all? If not, how is gay family any better or worse than a non-gay family?
2018-03-03T01:17:34 < BrainDamage> you're approaching it wrong, you're assuming that they think the law as something that benefits the society as whole vs a law that benefits them and they'd receive less money if the amount of people it's applied to grows bigger, even if that addition is a tiny fraction of the population
2018-03-03T01:20:08 < BrainDamage> so we have some people who are against gay marriages because of an insigificant economic gain
2018-03-03T01:24:56 < BrainDamage> there's an endless debate whenever extending partially those benefits to 'de facto' couples, but the same arguments gets thrown at it
2018-03-03T01:25:18 < BrainDamage> and on top of that, the usual religious ideologies
2018-03-03T01:26:02 < BrainDamage> church-state separation isn't much of a thing here on some aspects
2018-03-03T01:26:22 < BrainDamage> i guess there's too much history and strong ties
2018-03-03T01:31:53 < PaulFertser> Heh
2018-03-03T01:36:53 < PaulFertser> So they're discussing it not because it's really important for the lives but because they have no clue about what really affects them and how exactly, ok.

2018-03-03T11:26:57 < kakimir> are you guise sure that optimization change from debug optimized to O2 could not cause target sigfault?
2018-03-03T11:34:12 < kakimir> for some reason isp pin is in SWD pages and there is note to leave isp pin exposed to restore connection in case your binary goes shit

2018-03-03T11:45:33 < kakimir> For debugging purposes, it is useful to provide access to the ISP entry pin PIO0_1. This
2018-03-03T11:45:33 < kakimir> pin can be used to recover the part from configurations which would disable the SWD port
2018-03-03T11:45:33 < kakimir> such as improper PLL configuration, reconfiguration of SWD pins as ADC inputs, entry
2018-03-03T11:45:33 < kakimir> into Deep power-down mode out of reset, etc. This pin can be used for other functions
2018-03-03T11:45:33 < kakimir> such as GPIO, but it should not be held low on power-up or reset
2018-03-03T11:47:01 < kakimir> could inproper PLL confirugation cause sigfault using debugger and no problems when just flashed and ran without debugger?
2018-03-03T11:54:08 < kakimir> to say datasheet like lpc15xx doesn't mention using isp pin so

2018-03-03T13:01:56 < PaulFertser> kakimir: changing from -Og to -O2 certainly can expose some problems with your code.
2018-03-03T13:02:23 < kakimir> interesting
2018-03-03T13:02:27 < kakimir> better check that
2018-03-03T13:02:51 < kakimir> I have not had such problems with other targets
2018-03-03T13:02:55 < kakimir> like lpc15xx
2018-03-03T13:09:26 < PaulFertser> It doesn't matter, more aggressive optimisations are often leading to problems. That's why I would suggest to always use the optimisation level you plan for production, to see the issues early.
2018-03-03T13:10:10 < kakimir> well now I got them right away
2018-03-03T13:13:06 < PaulFertser> With minimal code?
2018-03-03T13:13:31 < PaulFertser> Then you can do "mon reset halt" and then step by assembly instructions. Until you see what's going on.

2018-03-03T21:51:03 < qyx> the SPWF04 module current consumption is ~29mA when idle and ~80mA when connected to an AP
2018-03-03T21:51:46 < qyx> enabling any from the available power saving modes makes it inaccessible from the network
2018-03-03T21:52:24 < qyx> besides that, in the sleep mode it consumes about 35mA which is still quite much
2018-03-03T21:52:48 < qyx> I didn't try the standby mode and the other one because it sleeps the whole module

2018-03-03T23:38:29 -!- syn0 [hoofman@odin.sdf-eu.org] has joined ##stm32
2018-03-03T23:38:30 < kakimir> yes
2018-03-03T23:41:28 < kakimir> sorry that I keep asking things but why it doesn't work without mon?
2018-03-03T23:41:45 < kakimir> and should I actually use mon by default then?
2018-03-03T23:42:01 < kakimir> *assuming debugging still works the same
2018-03-03T23:42:48 < PaulFertser> mon passes any command directly to openocd. If you place a breakpoint somewhere in reset vector and ask gdb to reset target, it'll stop on that breakpoint. Then you can avoid using mon. But if you want to ask the target to stop at the very start of reset vector, there's just no way to tell gdb that.

2018-03-03T23:44:37 < kakimir> oh
2018-03-03T23:44:50 < kakimir> mon actually stops it to the very start?
2018-03-03T23:45:18 < superbia2> gdb for dum dums
2018-03-03T23:45:23 < PaulFertser> No, mon just passes command to openocd. "reset halt" is the command to stop at the very beginning, yes.
2018-03-03T23:45:50 < PaulFertser> (mon is short for "monitor")

2018-03-03T23:48:42 < kakimir> so this mon reset halt goes to -c "..." of openocd command?
2018-03-03T23:49:35 < kakimir> I need to check my script
2018-03-03T23:50:27 < kakimir> ./bin/openocd -f ./share/openocd/scripts/interface/jlink.cfg -c "jlink serial 111111" -c "transport select swd" -f ./share/openocd/scripts/target/lpc11xx.cfg -c "init; reset halt"
2018-03-03T23:50:50 < kakimir> I ordered lpclink II also just in case
2018-03-03T23:53:36 < kakimir> I'll check that mon thing from manual
2018-03-03T23:54:44 < kakimir> I basically have made my openocd launch scripts and configurations by trial and error
2018-03-03T23:55:10 < kakimir> googling and asking PaulFertser for right direction
2018-03-03T23:57:45 < Steffanx> Y u no use random xpressocboard kakimir ?
2018-03-03T23:57:57 < kakimir> I forgot I had one

2018-03-04T00:22:40 < Steffanx> Yes, perole :p
2018-03-04T00:23:37 < kakimir> because openocd rules!
2018-03-04T00:24:58 < kakimir> jeez these grounded rj45 connectors
2018-03-04T00:25:17 < kakimir> I have been ircing and doing one cable for an hour and another end failed
2018-03-04T00:25:36 < kakimir> I only wonder how they manage to mass produce these
2018-03-04T00:26:06 < zyp> why do them yourself?
2018-03-04T00:26:19 < kakimir> it's really loose fit to thin copper
2018-03-04T00:26:29 < kakimir> I need 10cm patch
2018-03-04T00:26:36 < zyp> yeah?
2018-03-04T00:26:40 < zyp> just buy some?
2018-03-04T00:26:50 < kakimir> I want colors and all to match
2018-03-04T00:27:05 < kakimir> I needed to run some cables from attic from small hole
2018-03-04T00:27:27 < zyp> why are you running STP?
2018-03-04T00:27:47 < kakimir> because ubiquitis
2018-03-04T00:27:59 < zyp> wat?
2018-03-04T00:28:32 < kakimir> I happen to have the cable
2018-03-04T00:28:41 < stvn> THE DOLE
2018-03-04T00:28:42 < kakimir> from connecting some ubiquitis to injectors
2018-03-04T00:29:02 < zyp> well, sure, but if you can't terminate STP, just run UTP
2018-03-04T00:29:09 < kakimir> I had ready made patch and cut another end off to run it
2018-03-04T00:29:14 < stvn> stp is for gophers
2018-03-04T00:29:16 < kakimir> from holes
2018-03-04T00:31:04 < kakimir> it's beer a clock
2018-03-04T00:32:05 < zyp> is this ceiling mount unifi?
2018-03-04T00:32:26 < stvn> kakimir, beer o clock was all day yesterday
2018-03-04T00:33:14 < perole> STP is not the answer
2018-03-04T00:34:15 < perole> kakimir: at work we have almost 400 ubiquiti AP's and none of them are on STP
2018-03-04T00:34:29 < kakimir> cool
2018-03-04T00:34:53 < zyp> I'm wondering how to terminate the cables when I buy a house and put up some unifi APs
2018-03-04T00:35:18 < kakimir> https://drive.google.com/file/d/1Lu-Tw8nAUUOyylesUbWx_L0G56YVvlib/view?usp=sharing
2018-03-04T00:35:36 < kakimir> there is all visible things of networking system inside the house
2018-03-04T00:35:38 < zyp> gonna have conduit put in before they close up the ceiling/walls
2018-03-04T00:35:49 < kakimir> zyp, true
2018-03-04T00:35:56 < perole> hw quality is so-so, took a couple home for repair.  Same PCB manufacturer as my old d-link dir655
2018-03-04T00:36:46 < kakimir> ubiquiti?
2018-03-04T00:36:51 < zyp> just putting a RJ45 plug on the end of the cable coming out of the conduit seems a bit ghetto, but I don't think there's any sane way to fit a RJ45 jack behind the AP either
2018-03-04T00:36:51 < perole> yup
2018-03-04T00:37:19 < perole> zyp: I renovated in 2014, had the electricians put conduits while they were installing 220V
2018-03-04T00:37:37 < zyp> sure, running conduit is the easy part
2018-03-04T00:37:45 < zyp> I'm asking how to terminate it :)
2018-03-04T00:37:52 < perole> keystone
2018-03-04T00:38:09 < zyp> and then what?
2018-03-04T00:38:30 < perole> not sure about the english terms here.. :)

2018-03-04T00:38:39 < perole> elko veggboks, keystone
2018-03-04T00:38:53 < perole> samme boks som 220v
2018-03-04T00:38:57 < zyp> yeah, and then just leaving the jack loose in the box?
2018-03-04T00:39:16 < kakimir> https://drive.google.com/file/d/1uWPIyXIx35l-Nw_09399j3zyeSADJ3m5/view?usp=sharing white STP goes here into bullet 2
2018-03-04T00:39:29 < perole> nah, install proper rj45
2018-03-04T00:39:46 < zyp> I mean, without a faceplate
2018-03-04T00:39:50 < perole> with
2018-03-04T00:39:59 < zyp> next to the AP then?
2018-03-04T00:40:02 < perole> hold on, I may have a pic
2018-03-04T00:40:10 < perole> ah for AP's..
2018-03-04T00:40:16 < perole> buy ubiquiti in-wall
2018-03-04T00:40:34 < perole> and just terminate with rj45, yes :)
2018-03-04T00:40:55 < perole> I don't trust wifi, or at least didn't when I renovated, so have rj45 outlets in all rooms
2018-03-04T00:40:58 < zyp> nah, I want the ceiling mount ones
2018-03-04T00:41:12 < zyp> better radiation patterns and better MIMO
2018-03-04T00:41:17 < zyp> in-wall one is only 2x2
2018-03-04T00:41:48 < perole> for my desk/tv/fixed stuff, I want gig via cat6
2018-03-04T00:41:56 < zyp> sure, same
2018-03-04T00:42:08 < perole> for laptop/phones/ipads the normal ubiquiti stuff is fine
2018-03-04T00:42:19 < zyp> well, for my desk and server, I want 10gig via fiber
2018-03-04T00:42:27 < zyp> but still :p
2018-03-04T00:42:29  * karlp laughs
2018-03-04T00:43:02 < perole> zyp: got ubiquiti today?
2018-03-04T00:43:08 < zyp> yes
2018-03-04T00:43:16 < perole> allright, so then you know it really works :)
2018-03-04T00:43:35 < zyp> no question about that
2018-03-04T00:44:27 < zyp> haven't bothered putting it in the ceiling where I live now, so it's currently sitting on a shelf in my tv bench: https://bin.jvnv.net/file/1B1mQ.jpg
2018-03-04T00:45:23 < perole> yup, got an ac-lite in the livingroom and and in-wall in the bedroom.  90+sqm apartment, so all good
2018-03-04T00:45:33 < zyp> coverage seems to be a little bit worse than where I used to live, but not bad enough I've bothered to do anything about it
2018-03-04T00:45:46 < perole> the ac-lite is just laying on a shelf where I have my projector

2018-03-04T00:46:40 < zyp> https://bin.jvnv.net/file/L5AsC.JPG <- I used to have it in the ceiling before I moved
2018-03-04T00:46:44 < perole> I imagine a normal box with manually terminated rj45 would do the trick
2018-03-04T00:47:24 < zyp> well, the thing is, installation cable is usually single strand, which doesn't play too well with RJ45 plugs
2018-03-04T00:47:54 < perole> just have conduits to a central wiring thingie
2018-03-04T00:47:59 < Rob235> https://imgur.com/a/iGn8f gettin there
2018-03-04T00:48:07 < zyp> so I think I'd prefer terminating it in a keystone jack that I let hang loose in the box behind the AP, 10cm patch cord between it and the AP
2018-03-04T00:48:44 < perole> vacuum cleaner -> fishing line -> pull cable of choice thru
2018-03-04T00:49:07 < zyp> I've worked as an electrician, I know how to run cable :)
2018-03-04T00:49:25 < perole> then what are you bothering us for? :)
2018-03-04T00:49:40 < zyp> haha
2018-03-04T00:50:58 < zyp> https://bin.jvnv.net/file/h2qcM.JPG <- last place I rented, I somehow managed to run a fiber next to a pair of cat5 cables that were already in a conduit
2018-03-04T00:51:18 < zyp> once it was in, it got stuck hard enough that it's probably never coming out again :p
2018-03-04T00:51:31 < zyp> when I moved out, I just cut it and tucked the end into the box
2018-03-04T00:52:50 < perole> https://photos.google.com/share/AF1QipPsSanJzyYHDnqCDltA6nUOUTGoK9GwUEBcCaxmUR12-Cb8xfo0HBH2pPphQg2IHw/photo/AF1QipMZAljZz5aZcErTLdiL_OZh8x56FEzGIKPfPAN6?key=eW9wTGRfWDAzRk50M2Rlc0prQ2pVTmxCNHU5NkxR
2018-03-04T00:53:10 < perole> was a PITA to source the parts for that one
2018-03-04T00:53:32 < zyp> how so?
2018-03-04T00:53:40 < zyp> hdmi keystone jacks are easy to get
2018-03-04T00:53:48 < perole> elko box/frame whatever it's called
2018-03-04T00:53:51 < perole> they have their own system
2018-03-04T00:54:18 < perole> their rj45 is/was not keystone
2018-03-04T00:54:35 < zyp> sure, but RS16 keystone faceplates are easy to get too
2018-03-04T00:55:46 < zyp> e.g. https://elhandel.no/6941281-elko-rs16-sentralplate-ph-3x-keystone-tom
2018-03-04T00:56:45 < perole> don't remember all the details, but was a bunch of stuf from alcadon.no to make it happen
2018-03-04T00:57:09 < zyp> I considered doing keystone where I live now, but I took the easy route with a brush plate instead: https://bin.jvnv.net/file/ab4Em.jpg
2018-03-04T00:58:04 < zyp> https://bin.jvnv.net/file/RfYK8.jpg <- without plates
2018-03-04T00:58:43 < perole> a lot easier for sure, and it's not like you or your guests are going to stare it it for hours anyho
2018-03-04T01:00:54 < zyp> yeah, and when it's only passing directly through the wall anyway, it's not really worth adding connectors
2018-03-04T01:01:35 < zyp> keystone is more useful when you're terminating fixed cable in conduit
2018-03-04T01:03:22 < zyp> but when I'm buying a house, I'm gonna do stuff properly :)
2018-03-04T01:06:11 < zyp> https://www.atlasied.com/awr3w <- I'm thinking about getting something like this installed into the wall for the network central
2018-03-04T01:07:03 < zyp> that'll fit a patch panel and a proper switch, without having to sacrifice the depth that a traditional network rack consumes
2018-03-04T01:07:14 < perole> friend of mine redid a (big) house, conviced him to get a 42U rack in the basement :)
2018-03-04T01:08:04 < zyp> I'm thinking about maybe a 21U rack on wheels for server and shit
2018-03-04T01:08:19 < zyp> possibly smaller, I don't really have much rack shit
2018-03-04T01:09:47 < zyp> that way it'll only need power and network, and can easily get moved out of the way
2018-03-04T01:11:37 < zyp> might run a MTP cable for the network, that way I can have a fiber switch in the server rack and just break it out in the central rack
2018-03-04T01:11:54 < zyp> but I still don't really expect I'll need fiber at any other points than my desk and for the server :p
2018-03-04T01:12:31 < karlp> I just got wall jacks put in, normal female rj sockets on a wall plate like in an office

2018-03-04T16:35:27 < noonien> hello folks
2018-03-04T16:37:40 < noonien> what other compiled programming languages apart from C and C++ can be used to program stm32s?
2018-03-04T16:40:13 < PaulFertser> Rust
2018-03-04T16:40:18 < PaulFertser> Ada
2018-03-04T16:40:25 < PaulFertser> IvoryTower
2018-03-04T16:41:52 < PaulFertser> Those are the most popular and they come with some support for some peripherals already. Anything else you can compile for cortex-m will work too, but you'll probably have to write plenty of peripherals handling code.
2018-03-04T16:51:04 < karlp> I've seen forth usb device stack too.
2018-03-04T16:53:06 < PaulFertser> But is it compiled?

2018-03-04T17:46:42 < Cracki> I'm considering buying a dso quad (dso203), for about 120 bucks. is there something better (handheld) for a comparable price I should be aware of?
2018-03-04T17:55:46 < Rickta59> what are you going to do with it Cracki ?
2018-03-04T17:57:00 < Cracki> multitool for signal analysis. checking if power/signals are noisy. a simple protocol decoder and logger I can poke on appropriate lines of a PCB.
2018-03-04T17:57:25 < Rickta59> those saleae clones are like $10 if you are only doing digital stuff
2018-03-04T17:57:28 < Cracki> a kind of standalone LA. I have a cheap fx2 8ch 24mhz LA I can use with sigrok/pulseview already, and a decent multimeter.
2018-03-04T17:57:36 < blacktronics> should work fine for that then
2018-03-04T17:57:56 < Cracki> however, asking if there's a more recent device I'd rather want, if I knew of it
2018-03-04T17:58:32 < blacktronics> i am not up to date on that stuff either
2018-03-04T17:58:59 < blacktronics> i have been spending the last 2 days ripping my spine out over CubeMX and Keil
2018-03-04T17:59:14 < Cracki> sometimes I want to abuse spare gpios for debugging output. i could bitbang data on them, write a little program for the dso203, and have it print me the text... or even plot the integer values I toggle out
2018-03-04T18:02:04 < Rickta59> where did you find that for $120?
2018-03-04T18:02:23 < Cracki> aliex
2018-03-04T18:02:23 < Cracki> also euros
2018-03-04T18:02:29 < blacktronics> banggood also has them
2018-03-04T18:02:39 < Cracki> also hw2.82, which is the newest
2018-03-04T18:03:19 < Cracki> banggood isn't cheap enough
2018-03-04T18:03:41 < Cracki> it's more for consumer electronics and toys, not for proper devices
2018-03-04T18:04:05 < blacktronics> >proper device
2018-03-04T18:04:09 < blacktronics> >chinese scope
2018-03-04T18:04:11 < blacktronics> ok
2018-03-04T18:05:10 < Cracki> it's cheap
2018-03-04T18:05:35 < Cracki> that's ok. I know the limitations of that thing. I've read a bunch about it.
2018-03-04T18:06:03 < blacktronics> ye
2018-03-04T18:09:32 < Cracki> some homebrew 2016 firmware also really tries to get the most out of the hardware, compensate for some of its flaws
2018-03-04T18:13:54 < Cracki> https://www.seeed.cc/Wildcat-for-DSO-Quad-DSO203-Newbies-t-10794.html
2018-03-04T18:15:58 < noonien> PaulFertser: thanks, i'll give ada a run, and check out IvoryTower
2018-03-04T18:16:10 < noonien> Nim is pretty cool as well
2018-03-04T18:16:54 < noonien> i've started to hate c/c++ includes/preprocessors with a passion, and i'm trying to find some sane alternatives, along with a decent build system
2018-03-04T18:19:12 < Rickta59> nim seems like it is meant more for doing database stuff than embedded
2018-03-04T18:19:56 < Rickta59> i would think with non c languages you are going to be battling the peripheral setup and usage
2018-03-04T18:22:01 < noonien> hmm, nim seems like a general purpose language
2018-03-04T18:22:31 < noonien> i'll give zig a try aswell once it has support for softfloat
2018-03-04T18:22:51 < noonien> nim, zig, terra all have support for importing C code
2018-03-04T18:23:05 < noonien> that should give me more than enough flexibility with setup/peripherals i believe

2018-03-04T20:15:37 < kakimir> and start conducting heat efficiently when melted?
2018-03-04T20:23:12 < englishman> pure potassium
2018-03-04T20:27:00 < kakimir> you sure?
2018-03-04T20:28:08 < kakimir> I want a device to heat up to around 70celsius and then form a thermal contact
2018-03-04T20:30:10 < kakimir> preferably a solution that is passive and without mechanics or electric power
2018-03-04T20:31:15 < kakimir> maybe a huge bimetal strip :o
2018-03-04T20:32:17 < kakimir> hmm potassium is 64celsius
2018-03-04T20:32:27 < kakimir> sounds corrosive
2018-03-04T20:32:38 < kakimir> there is aluminium involved *
2018-03-04T20:34:47 < kakimir> potasium is way too reactive
2018-03-04T20:35:10 < kakimir> galium is not an option
2018-03-04T20:36:29 < kakimir> unless contacts are made from copper and have insulation to sides

2018-03-04T20:40:18 < kakimir> maybe there would be hydrocarbon that would start boiling around 70C
2018-03-04T20:40:57 < kakimir> hexane
2018-03-04T20:41:29 < kakimir> are you saying I should fill it with gasoline
2018-03-04T20:44:49 < kakimir> so the container should withstand multiple kilos of pressure without rupturing
2018-03-04T20:45:03 < kakimir> not a fan of that
2018-03-04T20:45:28 < kakimir> square container would not stay square
2018-03-04T20:47:23 < jpa-> how about just a normal heatpipe with alcohol/isopropanol inside?

2018-03-04T21:13:01 < Steffanx> whats the plan anyway, kakimir?
2018-03-04T21:13:17 < kakimir> we need heat
2018-03-04T21:13:34 < kakimir> but not too much
2018-03-04T21:15:35 < kakimir> operated in cold conditions
2018-03-04T21:16:18 < englishman> how about a thermal valve of some kind
2018-03-04T21:16:23 < englishman> like could be found in a car
2018-03-04T21:16:28 < englishman> to regulate temperature
2018-03-04T21:16:49 < englishman> possibly utilizing a bimetallic element
2018-03-04T21:16:51 < kakimir> size restriction
2018-03-04T21:17:01 < kakimir> and strictly no mechanics
2018-03-04T21:17:14 < kakimir> absolutelly solid operation

2018-03-04T21:17:46 < kakimir> this is just one of the pro projects
2018-03-04T21:17:49 < blacktronics> so i just made a new µVision project for an STM32F746G-Discovery, trying to flash it just throws "No Algorithm found for: 00200000H - 00203DC7H", is there anything else i have to set?
2018-03-04T21:20:19 < kakimir> englishman, making prototypes and sourcing parts are the hard part
2018-03-04T21:20:34 < kakimir> we will visit a simulation company week after next week
2018-03-04T21:20:35 < englishman> especially when you are working with pure potassium

2018-03-04T21:21:42 < jpa-> i mean the programmer software
2018-03-04T21:21:48 < kakimir> how do they seal heatpipes?

2018-03-04T21:24:02 < kakimir> blacktronics, are those heat pipes produced in cold or in pressured conditions or both?
2018-03-04T21:24:51 < blacktronics> kakimir: not exactly sure how they do it, i would assume they are unpressurized, it's evaporative cooling after all
2018-03-04T21:25:18 < kakimir> and that thing too
2018-03-04T21:25:37 < kakimir> you know ammonia and methanol wont really stay liquid in room temperature
2018-03-04T21:25:44 < blacktronics> but with copper i always recommend soldering, welding copper is comparably too much effort and requires ridiculous heat
2018-03-04T21:25:49 < jpa-> blacktronics: can you check from the memory map whether it is trying to load something into 0x200000 address? that would mean that your program exceeds the 2MB flash size
2018-03-04T21:26:22 < blacktronics> jpa-: only have 1 mb flash, where do i check that?
2018-03-04T21:27:23 < blacktronics> kakimir: apparently people are making their own heatpipes, not sure how much specialized equipment you need
2018-03-04T21:27:36 < jpa-> atleast it should show flash usage when compiling i think
2018-03-04T21:27:42 < kakimir> hmm.. they put water in them
2018-03-04T21:27:46 < kakimir> shiet
2018-03-04T21:28:05 < kakimir> so that has boiling point 100C

2018-03-04T21:32:00 < kakimir> to keep virtual conduction only operation as long as possible
2018-03-04T21:33:37 < blacktronics> jpa-: i went into target options and pressed buttons and now it does this
2018-03-04T21:33:42 < blacktronics> https://www.irccloud.com/pastebin/6D8UygIx/
2018-03-04T21:33:56 < blacktronics> keil go home ur drunk
2018-03-04T21:34:58 < blacktronics> well, what i did was go into Target Options->Utilities->Target Driver Setup and removed the chip and added it back
2018-03-04T21:38:23 < blacktronics> maybe dongs aka keil pro 4 lyfe knows?
2018-03-04T21:44:19 < kakimir> blacktronics, there is only vapour pressure inside
2018-03-04T21:44:35 < kakimir> that makes the whole thing much more complicated
2018-03-04T21:47:47 < blacktronics> kakimir: that's just having the liquid at a specific pressure though, right?
2018-03-04T21:48:12 < kakimir> hey hey
2018-03-04T21:48:18 < kakimir> we are getting there
2018-03-04T21:48:24 < kakimir> I have seen such tables
2018-03-04T21:48:49 < blacktronics> Ye they're called phase diagrams
2018-03-04T21:49:41 < Rob235> ugh this pen holder keeps getting more and more complicated
2018-03-04T21:50:18 < kakimir> blacktronics, I mean i was looking at some refrigerant sheets
2018-03-04T21:50:24 < Steffanx> stop overengineering Rob235 :P
2018-03-04T21:51:54 < Rob235> I need to learn better design organization.  I think it will be trivial to add things in the end and it never is.

2018-03-04T21:57:30 < kakimir> never done that
2018-03-04T21:58:37 < kakimir> does the volume of liquid in constant volume space affect the properties of heatpipe?

2018-03-04T22:24:41 < blacktronics> kakimir: you mean software or physical?
2018-03-04T22:24:49 < kakimir> software certainly
2018-03-04T22:24:54 < blacktronics> Solidworks can probably do it

2018-03-04T22:26:14 < kakimir> I need something more aids
2018-03-04T22:26:32 < kakimir> read: cheaper
2018-03-04T22:27:09 < blacktronics> not sure
2018-03-04T22:27:20 < blacktronics> google for fluid dynamics simulation
2018-03-04T22:27:52 < kakimir> openfoam
2018-03-04T22:28:18 < kakimir> it's not like first project type of thing to simulate capilary layer in heat pipe
2018-03-04T22:29:21 < kakimir> you probs need to do some trick to approximate the crapilary layer
2018-03-04T22:29:47 < kakimir> I'm not sure if simulation even accounts capilary effect
2018-03-04T22:33:38 < upgrdman> so i bought a cheap induction cooktop after bitching about my shit electric stove. holy fuck, such amaze. 10/10 would recommend. best $57 i've spent this year.
2018-03-04T22:36:04 < kakimir> thing about electric stove is delay
2018-03-04T22:36:45 < kakimir> I'm ircin like 10minutes in and realize I left it to 6/6 so it has got intense in there
2018-03-04T22:38:14 < kakimir> basically doing PID-controlling manually by setting heat to for maximum delta T and then forget the whole thing
2018-03-04T22:38:34 < kakimir> and it goes way over the intended temperature

2018-03-04T22:41:58 < sync> no
2018-03-04T22:42:08 < sync> that is just regular one with glass ceramic top
2018-03-04T22:42:12 < upgrdman> o ok
2018-03-04T22:42:34 < sync> halogen basically has a high powered spot light shining upwards
2018-03-04T22:42:49 < upgrdman> so wear sunglasses when cooking ;) ?

2018-03-04T22:52:30 < kakimir> keep about constant temperature in certain areas of the device
2018-03-04T22:53:30 < kakimir> if it was +40C ambient or -40C ambient - it should stay within certain limits
2018-03-04T22:54:14 < kakimir> and yah.. with current cooling solution you need to dump like 500watts of excess power in there to archive that
2018-03-04T22:54:15 < catphish> morning, i am a clueless noob with a ton of questions about the stm32 i am developing on, i apologize in advance for all of them

2018-03-04T22:56:27 < kakimir> and just ask - it's the rule
2018-03-04T23:04:06 < karlp> hrm, terra looks insane but maybe interesting for metameta
2018-03-04T23:04:27 < karlp> zig looks interestingish, but depsite talking baout cross compiling as a first class usecase, gives no mention of it whatsoever in it's docs
2018-03-04T23:06:51 < catphish> kakimir: thanks, will do, still wading through documentation for now

2018-03-04T23:08:01 < kakimir> and stuff here also gets weird(offtopic) sometimes so don't get confused

2018-03-05T00:19:59 < karlp> are you sure it's misreading adc, or was the adc always misreading and you just never saw it before?
2018-03-05T00:21:11 < HelloFriends> @karlp when removing a dma function, the ADC reads correct values, otherwise, it has erratic readings that coincide with timing of a DMA transfer.

2018-03-05T00:43:27 < upgrdman> Adluc, i had zero failure when doing lots of 0603's and QFNs, and i didnt even use an oven. just a heat gun. the "trick" is to use a paste stencil. if you just squirt paste from a syringe, then ya, LOTS of bridges and tombstones.
2018-03-05T00:44:02 < upgrdman> Adluc, http://www.farrellf.com/temp/stenciled_solderpaste.jpg

2018-03-05T00:44:33 < upgrdman> :)
2018-03-05T00:45:36 < upgrdman> actually, on the QFNs i may have had to remove a couple bridges. but no problems on any passives.
2018-03-05T00:46:12 < Adluc> cool :D especially the notches in paste on caps
2018-03-05T00:48:36 < Steffann> A heat gun.. not even something with kinda proper temp control -_-

2018-03-05T00:50:36 < upgrdman> Adluc, theres a GND pour on the back side
2018-03-05T00:50:37 < Adluc> oh, ok
2018-03-05T00:50:49 < upgrdman> it was just a cheap 2-layer board, so no VDD pour
2018-03-05T00:51:00 < Rob235> https://imgur.com/a/bKVHl
2018-03-05T00:51:08 < Rob235> messed up the print but it fits well
2018-03-05T00:54:03 < zyp> upgrdman, got a pic of the back?
2018-03-05T00:56:04 < upgrdman> zyp, not with me. but i has altidumb screenshot if you want
2018-03-05T00:58:38 < zyp> I'm just curious how much signals you've routed on the bottom
2018-03-05T00:59:24 < zyp> on a 2L board, you'll normally want to do ground pours on both layers and stitch them so they together form a decent ground plane
2018-03-05T01:04:01 < upgrdman> zyp, http://www.farrellf.com/temp/back.png
2018-03-05T01:04:35 < upgrdman> ya not the best layout but it was a quick prototype. testing to see if an idea would work, for later integration into coworker's pcbs
2018-03-05T01:04:43 < upgrdman> and it worked, so yay for me.
2018-03-05T01:05:24 < zyp> yeah, that ground pour is probably pretty much pointless as a ground plane
2018-03-05T01:05:53 < upgrdman> k
2018-03-05T01:06:09 < zyp> it'll of course give connectivity just as well as if you routed ground with traces
2018-03-05T01:06:18 < upgrdman> ya
2018-03-05T01:06:27 < upgrdman> i wasnt too worried about parasitic inductance
2018-03-05T01:06:36 < zyp> but all the signals cutting into it means it won't act as a good reference ground for signals on top layer

2018-03-05T01:29:53 < catphish> what APIs do people tend to use for stm32, i'm a bit torn, i really dislike the high level HAL API, but i also dislike endlessly defining register names when writing from scratch, is there some middle ground?
2018-03-05T01:31:03 < zyp> libopencm3 is popular
2018-03-05T01:31:49 < catphish> i did have a look at that, couldn't get it set up correctly, perhaps i should try again
2018-03-05T01:32:34 < zyp> I would probably have gone with libopencm3 if I started today
2018-03-05T01:34:08 < catphish> right now i'm looking to set up a timer with pwm and update its pulse width, i am finding this unusually difficult, but i think i just haven't found the right combination of libraries and documentation yet
2018-03-05T01:34:27 < catphish> the docs are all written with register names in mind, so i'd like to just address those
2018-03-05T01:34:58 < zyp> you get headers with just the registers defined too, not sure exactly where you get them though
2018-03-05T01:35:22 < zyp> I'm using my own lib, which I forked out of some scratch-written code I wrote seven years ago or so
2018-03-05T01:35:31 < sync> PaulFertser, you might know this, what is the state of etm/itm trace in openocd?
2018-03-05T01:36:06 < zyp> but naturally that only supports what I've needed it to do so far, so I don't really advise other people to use that unless they're specially interested
2018-03-05T01:36:57 < zyp> it's written with the same idea as you have though
2018-03-05T01:37:09 < catphish> i suppose i could start over, linking to the official libs but not using the project generator that generates everything in HAL style
2018-03-05T01:37:51 < catphish> libopencm3 looks great too
2018-03-05T01:45:47 < catphish> after writing my own entire boot code, i think the concepts are a lot clearer, i should be able to just copy/link the official API now as needed
2018-03-05T01:48:26 < catphish> taking this approach makes a lot more sense to me now that it did when i read it yeaterday, so will press ahead: http://regalis.com.pl/en/arm-cortex-stm32-gnulinux/
2018-03-05T01:48:31 < catphish> thanks for the pointers

2018-03-05T17:03:29 < englishman> well
2018-03-05T17:03:38 < englishman> this package was supposed to be here friday
2018-03-05T17:03:50 < englishman> it shipped from wooden-shoe-land this morning
2018-03-05T17:04:16 < karlp> maybe they had skaters deliver it and they fell int he canal
2018-03-05T17:05:00 < englishman> yesterday i saw an ice floe in the river that had snowmobile tracks on it
2018-03-05T17:05:02 < englishman> spring is here
2018-03-05T17:05:13 < Steffanx> Lol why arrow ships from dutchland?!
2018-03-05T17:05:45 < Steffanx> The canals are frozen karlp
2018-03-05T17:06:06 < karlp> I know, that's why I said skaters, and why I said fall in :)
2018-03-05T17:06:23 < Steffanx> Or were frozen. Its +10C again
2018-03-05T17:06:35 < BrainDamage> here temp is taking massive swings
2018-03-05T17:06:43 < karlp> I saw in the news some skaters had fallen though last friday
2018-03-05T17:06:46 < BrainDamage> past week max temp was -5, next week is going to be 15
2018-03-05T17:07:07 < Steffanx> Yeah, same here. It was -10 last week, now its +10
2018-03-05T17:07:33 < Steffanx> I blame the russians. They sent us some cold air.
2018-03-05T17:09:32 < BrainDamage> I'm sure r2com would do that seriously
2018-03-05T17:10:22 < Steffanx> Hehe. Absolutely.

2018-03-05T20:04:28 < Steffanx> zyp: I could actually skate to work if they would stop the ships in the canals from breaking the ice
2018-03-05T20:05:01 < Steffanx> oh, and it's +10C now, so not safe to be on the ice anymore.
2018-03-05T20:05:32 < Steffanx> What about you zyp? A norwegian won the ice skating world cup last weekend

2018-03-05T21:51:25 < Steffanx> will you print in the air or with support Rob235?
2018-03-05T21:51:50 < Rob235> havent decided yet
2018-03-05T21:52:07 < Rob235> I havent messed with overhangs much yet so I might just do supports for now
2018-03-05T21:52:18 < Steffanx> better get some petg.
2018-03-05T21:52:40 < Steffanx> much more flexible

2018-03-05T22:12:49 < Steffanx> Good morning sir.
2018-03-05T22:13:16 < BrainDamage> good morning, how many animals did threat your life this week?

2018-03-05T22:14:52 < BrainDamage> still better than wallabies
2018-03-05T22:15:05 < englishman> it is very unfinnishlike to /ignore

2018-03-05T22:38:49 < Steffanx> They work like a charm
2018-03-05T22:38:55 < englishman> :D
2018-03-05T22:39:06 < Steffanx> Much easier than messing around with keygens/whatever windows activation crap
2018-03-05T22:39:57 < englishman> even easier than buying a license from Microsoft too, i think
2018-03-05T22:40:07 < Steffanx> and cheaper

2018-03-05T22:48:40 < Steffanx> as update?
2018-03-05T22:48:48 < englishman> as an upgrade from win8 yes
2018-03-05T22:49:16 < Steffanx> and 7
2018-03-05T22:49:31 < zyp> hmm, when I think about it, I still have win7 on this computer
2018-03-05T22:49:36 < zyp> (which I never use)
2018-03-05T22:50:02 < zyp> IIRC I grabbed the key from another computer and validated it
2018-03-05T22:50:14 < Steffanx> :)
2018-03-05T22:50:38 < zyp> bought a couple of cheap refurb machines a few years back, and they each came with a win7 license
2018-03-05T22:50:45 < zyp> and I'm not running win7 on them
2018-03-05T22:51:02 < zyp> so IIRC I put one of those licenses on my workstation
2018-03-05T22:51:39 < zyp> by cheap I mean ~$65
2018-03-05T22:52:35 < Steffanx> Those ebay ones are like $5. And ebay seems to accept it, because the seller has been around for a while
2018-03-05T22:52:43 < Rob235> https://imgur.com/a/OKJFp
2018-03-05T22:52:47 < Rob235> what what? in the butt!
2018-03-05T22:53:22 < Steffanx> Uhm, they have better communities for hobbies like that Rob235
2018-03-05T22:53:37 < Rob235> :)
2018-03-05T22:55:44 < zyp> Steffanx, yeah, but then you don't get a spare computer as well :p
2018-03-05T22:56:20 < Steffanx> I gave up on that a looong time ago.
2018-03-05T22:56:27 < zyp> hehe
2018-03-05T22:56:51 < zyp> I was looking at blade servers earlier today
2018-03-05T22:57:08 < zyp> dunno what I'd need it for
2018-03-05T22:57:17 < Steffanx> When it's not  faster than my works station and already have a serverish thing.. i dont need such spare pc.
2018-03-05T22:57:24 < zyp> true
2018-03-05T22:57:52 < zyp> when I had electricity included in rent, it was fun to run all sorts of shit
2018-03-05T22:58:07 < zyp> not that fun when I have to pay for the power consumption :p
2018-03-05T22:58:08 < Steffanx> Yeah. Before buttcoin was hot i guess.
2018-03-05T22:58:22 < zyp> not necessarily
2018-03-05T22:58:34 < emeb> hmm... how many computers - workstation, bookshelf server, Win7 laptop for running Word / Excel, travel laptop, livingroom laptop.
2018-03-05T22:58:39 < emeb> too damn many computers
2018-03-05T22:59:03 < zyp> that's a lot of laptops
2018-03-05T22:59:35 < emeb> Plus a box full of all the dead laptops my relatives gave me to destroy.
2018-03-05T22:59:47 < emeb> there's probably ten in that box.
2018-03-05T22:59:53 < zyp> I mean, I still have all three laptops I've ever bought, but I only use the macbook
2018-03-05T22:59:58 < zyp> and that's just barely
2018-03-05T23:00:59 < emeb> didn't you have a hackintosh or something?
2018-03-05T23:01:12 < zyp> yes, that's my workstation
2018-03-05T23:07:05 < emeb> my livingroom laptop is a macbook that's so old there are no longer any supported web browsers for it. Nothing current runs on 10.6.8
2018-03-05T23:08:12 < emeb> Every so often some website becomes unbrowsable - I can't go to adafruit.com for example because old chrome hates their new authentication.
2018-03-05T23:08:30 < Streaker> I want one of the new 56 core Xeon motherboards
2018-03-05T23:09:07 < zyp> no, you don't
2018-03-05T23:09:42 < Streaker> Why not?
2018-03-05T23:10:09 < emeb> do you have software that could actually use that many simultaneous threads?
2018-03-05T23:10:15 < englishman> chrome.exe
2018-03-05T23:12:38 < kakimir> friend has 64GB of ram to run firefox 15
2018-03-05T23:12:50 < kakimir> with over thousand tabs on it
2018-03-05T23:13:37 < emeb> I keep a lot of tabs open but what's the point in having more than you can see across the top of the browser?
2018-03-05T23:14:42 < zyp> same
2018-03-05T23:14:45 < kakimir> he is kind of guy to ask a thing and he returns a related url in 15seconds
2018-03-05T23:14:50 < kakimir> anything
2018-03-05T23:14:56 < kakimir> he has it already open
2018-03-05T23:14:59 < zyp> I usually start cleaning up when they get narrow enough that icons start disappearing
2018-03-05T23:15:11 < kakimir> same thing
2018-03-05T23:15:38 < kakimir> but there is additions to browser where you can push and pop them tabs to lists
2018-03-05T23:15:52 < englishman> i guess that is why people are buying ultra widescreen monitors
2018-03-05T23:16:07 < zyp> https://bin.jvnv.net/file/g8bTd.png <- right now it looks like this
2018-03-05T23:16:32 < kakimir> englishman, it's because it's easier to look at sides than up
2018-03-05T23:16:45 < kakimir> ergonimics 101
2018-03-05T23:17:11 < kakimir> besides you need to cosntantly look up and down
2018-03-05T23:17:20 < kakimir> navigating
2018-03-05T23:17:46 < kakimir> but what you actually do then is constrained in small area of display
2018-03-05T23:17:58 < kakimir> not usually the whole display
2018-03-05T23:18:45 < kakimir> it's weird era
2018-03-05T23:18:49 < kakimir> sub facebook era
2018-03-05T23:18:53 < kakimir> *post
2018-03-05T23:19:23 < kakimir> everybody is there but nobody really uses it to anything but promotion purposes anymore
2018-03-05T23:19:42 < kakimir> advertisements is all the shapes and forms
2018-03-05T23:23:35 < kakimir> :D
2018-03-05T23:24:12 < kakimir> no!!

2018-03-06T03:09:00 < dongs>  < emeb> Every so often some website becomes unbrowsable - I can't go to adafruit.com for example
2018-03-06T03:09:06 < dongs> I would consider that a plus
2018-03-06T03:09:15 < dongs> nobody SHOULD be going to aidsfruit.com anyway.
2018-03-06T03:09:58 < emeb> dongs: :)
2018-03-06T03:10:29 < emeb> Was looking for an rpi0w the other day - they were the best deal.
2018-03-06T03:11:46 < aandrew> fucking altidumb
2018-03-06T03:12:09 < dongs> emeb: was it $5
2018-03-06T03:12:13 < dongs> or liek $55
2018-03-06T03:12:22 < dongs> with a special kawaii pinku case
2018-03-06T03:12:48 < dongs> can you believe they charge real $ now to get a rageberry with that pinheader soldered on it
2018-03-06T03:12:55 < dongs> the maker:s are THAT LAZY
2018-03-06T03:12:58 < aandrew> hey soldering is hard boys
2018-03-06T03:14:43 < emeb> dongs: didn't need case/accessories/etc so it was $10 for the one with wifi
2018-03-06T03:14:56 < emeb> another $5 for shipping
2018-03-06T03:16:16 < dongs> not bad.
2018-03-06T03:23:21 < emeb> yeah - can't complain about getting a fairly usable wireless network-enabled computer for that much. Hooked it up to my little Lattice FPGA board and was able to build the bitstream on the rpi using those FOSS icestorm tools. Kinda amazing.
2018-03-06T03:25:26 < dongs> emeb, i think i asked you this before
2018-03-06T03:25:30 < dongs> about bottom-mounted rotary encoders
2018-03-06T03:25:38 < dongs> and i found out chinks just bent the old board
2018-03-06T03:26:57 < emeb> dongs: don't recall the subject coming up  before - by "bottom mounted" do you mean only held in place by the PCB & no hardware / nuts etc to the panel/case?
2018-03-06T03:27:05 < dongs> no
2018-03-06T03:27:16 < dongs> the thread in teh knob is through a hole in pcb
2018-03-06T03:27:20 < dongs> and dip legs bend up
2018-03-06T03:27:28 < dongs> (the 3 pins)
2018-03-06T03:27:41 < emeb> dongs: ah - very strange configuration. Never seen that before.
2018-03-06T03:27:54 < dongs> https://www.broadcom.com/products/motion-control-encoders/rotary-switches/hrpg-ad1616c
2018-03-06T03:28:02 < dongs> this is teh closest i can find that isnt a chink hand-bent clone
2018-03-06T03:28:55 < emeb> dongs: that's pretty cool actually. I know some folks who migh be interested in that.
2018-03-06T03:29:21 < dongs> well, what c hina does is literalyl takes the standard encoder
2018-03-06T03:29:29 < emeb> very funny that it's from broadcom - don't usually associate them with hardware like that.
2018-03-06T03:29:52 < dongs> well, i wouldnt use the broadcom thing
2018-03-06T03:29:57 < dongs> what china does is literally takes the generic encoder
2018-03-06T03:29:57 < dongs> https://ae01.alicdn.com/kf/HTB1mW74KVXXXXbkXpXXq6xXFXXXi/3-Pcs-lot-6mm-D-Shaft-18-Position-360-Degree-Rotary-Encoder-w-Push-Button-Switch.jpg_640x640.jpg
2018-03-06T03:30:05 < dongs> and bends those 3 legs up with pliers
2018-03-06T03:30:07 < dongs> so they're facing up
2018-03-06T03:30:11 < dongs> and mount it from the back
2018-03-06T03:31:07 < emeb> lol
2018-03-06T03:31:14 < emeb> such a hack
2018-03-06T03:35:30 < dongs> it.. works but shitty
2018-03-06T03:35:42 < emeb> and requires hand labor
2018-03-06T03:35:52 < emeb> so results are not consistent I suspect.
2018-03-06T03:36:09 < emeb> depends on how much the assembly ladies were drinking the night before...
2018-03-06T03:36:10 < dongs> right
2018-03-06T03:38:21 < emeb> dongs: how much call is there for controls mounted like that?
2018-03-06T03:38:44 < emeb> I see a lot of this with shoestring stuff in the Euro Synth market where people use PCBs as front panels
2018-03-06T03:38:55 < dongs> emeb: this fuckface im makign a control surface for designed a case around it.
2018-03-06T03:38:56 < emeb> but it seems like it wouldn't be great in mass-produced consumer goods.
2018-03-06T03:39:05 < dongs> without asking anyone
2018-03-06T03:39:14 < dongs> cuz china used those once
2018-03-06T03:39:20 < dongs> and he thought it was ok for mp
2018-03-06T03:39:38 < emeb> yeah
2018-03-06T03:40:03 < emeb> then you have the solder lugs protruding thru to where people can touch them
2018-03-06T03:40:06 < emeb> seems bad
2018-03-06T03:40:10 < dongs> and i'd bet that broadcom optical encoder is at least $100
2018-03-06T03:40:13 < dongs> assuking you can even buy it
2018-03-06T03:40:17 < emeb> heh
2018-03-06T03:40:25 < dongs> emeb: well, its under a plastic case
2018-03-06T03:40:34 < emeb> ah - not so bad then
2018-03-06T03:40:46 < emeb> I've got some products out there now with optical encoders
2018-03-06T03:41:00 < emeb> Bourns stuff. About $9/ea in qty
2018-03-06T03:41:29 < dongs> oh wow, tehy're on mouser
2018-03-06T03:41:35 < emeb> http://synthtech.com/img/eurorack/E370.jpg
2018-03-06T03:41:36 < dongs> 32bux in singles for most expensive one
2018-03-06T03:41:37 < dongs> the rest nonstock
2018-03-06T03:41:49 < dongs> i guess better than I expected
2018-03-06T03:42:03 < dongs> the reverse mount one isnt stocked
2018-03-06T03:42:07 < dongs> and MOQ is 150
2018-03-06T03:42:09 < emeb> those broadcom things?

2018-03-06T03:42:15 < dongs> yes
2018-03-06T03:42:33 < emeb> not cheap
2018-03-06T03:44:32 < Ultrasauce> 28x $9 encoders...no wonder modular shit is so expensive
2018-03-06T03:44:48 < dongs> heh
2018-03-06T03:44:56 < emeb> Ultrasauce: Nah - most of those are pots
2018-03-06T03:45:04 < Ultrasauce> ah ok
2018-03-06T03:45:08 < emeb> there's only one encoder down in the bottom left corner
2018-03-06T03:45:21 < emeb> the rest are BI/TT pots that cost about $4 in qty. :)
2018-03-06T03:45:49 < emeb> And that's just cause my client is picky about pots - most other mfgs use pots that are similar but cost more like $1
2018-03-06T03:46:31 < Ultrasauce> mine is all still sitting on breadboards and detunes if you hit the table
2018-03-06T03:47:30 < emeb> analog expo converters?
2018-03-06T03:47:33 < Ultrasauce> ya
2018-03-06T03:47:42 < emeb> those are a PITA
2018-03-06T03:48:09 < emeb> all my oscillator designs are DSP with crystal reference. avoids a lot of hassle.
2018-03-06T03:48:37 < Ultrasauce> pffh digital. bet your soundstage is super narrow

2018-03-06T13:39:49 < kaa> me neather
2018-03-06T13:40:21 < kaa> I see there is no 2U in 8bits left
2018-03-06T13:40:30 < kaa> or 1U 0bits left
2018-03-06T13:41:15 < kaa> without counting
2018-03-06T13:41:53 < kaa> in registery operations register is writen first and then read right?
2018-03-06T13:42:09 < zyp> question doesn't make sense
2018-03-06T13:42:17 < qyx> C doesnt even support binary literals
2018-03-06T13:42:33 < zyp> qyx, didn't C11 add that?
2018-03-06T13:42:42 < qyx> iirc it was rejected
2018-03-06T13:42:43 < qyx> or not?
2018-03-06T13:42:55 < zyp> dunno
2018-03-06T13:42:55 < kaa> I mean if I read register value after writing it is actual register value what I read?
2018-03-06T13:42:57 < qyx> theres some gcc extension
2018-03-06T13:43:16 < kaa> I don't use binary
2018-03-06T13:43:20 < qyx> it may not be
2018-03-06T13:43:29 < zyp> hmm, C++ added it in C++14
2018-03-06T13:43:42 < zyp> then it makes sense it didn't make it into C11
2018-03-06T13:43:44 < kaa> I need to check what I write there with temp variable
2018-03-06T13:44:02 < zyp> C11 is mostly stuff from C++11 that they wanted in C as well, IIRC
2018-03-06T13:45:16 < tomeaton17> Get a prerelease version of the next c++ by using boost :p
2018-03-06T13:54:14 < kaa> why can't I add watchpoints in eclipse?
2018-03-06T13:54:21 < kaa> my hw should have 2 watchpoints
2018-03-06T13:54:43 < kaa> Toggle watchpoint button is shaded
2018-03-06T13:55:43 < kaa> oh it probs can do only global variables?
2018-03-06T13:57:27 < kaa> I changed my release to optimize for debug btw. no negative effect - works as well as O2
2018-03-06T14:04:15 < kaa> okay value was right it was just debugging issue to have right value to come out

2018-03-06T15:10:46 < dongs> +/- on keypad
2018-03-06T15:11:07 < dongs> i have that bound to side mouse buttons on my shit, so I can switch top/botom/middleetc layers with a click
2018-03-06T15:11:40 < perole> sounds too easy, layer SETS, not layers
2018-03-06T15:11:44  * perole fires up altium
2018-03-06T15:12:04 < dongs> i know what layer sets are, but I never found them useful
2018-03-06T15:12:11 < dongs> shift-s and switching layers is way easier
2018-03-06T15:12:53 < perole> yeh, do that stuff already - switch between layers on mouse
2018-03-06T15:13:26 < perole> mostly for placement, nice to have mechanical layer
2018-03-06T15:14:20 < perole> alternative is to make a 'routing layer set' with mech15 included

2018-03-06T15:25:41 < dongs> reducing as in O0, or just a lower level?>

2018-03-06T16:13:08 < dongs> next window plz
2018-03-06T16:13:26 < blacktronics> its interestingly a very similar issue to what tomeaton17 has
2018-03-06T16:13:47 < dongs> ive only seen it once on my shit, when I was doing non-pack thing with a F405
2018-03-06T16:13:48 < blacktronics> except on a stm32f746 disco and only on a fresh keil project
2018-03-06T16:13:58 < blacktronics> the examples work fine
2018-03-06T16:14:15 < blacktronics> https://www.irccloud.com/pastebin/cvH5mvt2/
2018-03-06T16:14:19 < blacktronics> literally does this
2018-03-06T16:14:44 < dongs> .. thats not even flash or ram
2018-03-06T16:14:51 < dongs> looks like your memory map shit is fucked up
2018-03-06T16:15:08 < blacktronics> where fix
2018-03-06T16:15:27 < dongs> all teh shit in target options dialog
2018-03-06T16:15:29 < dongs> compare with examples
2018-03-06T16:15:32 < dongs> and see what you set wrong
2018-03-06T16:15:33 < blacktronics> yeah i did
2018-03-06T16:15:36 < blacktronics> its the same
2018-03-06T16:16:24 < tomeaton17> yeah I cocked someting up in it
2018-03-06T16:16:29 < blacktronics> initially it didnt even do the partial programming thing
2018-03-06T16:16:35 < tomeaton17> I think I may have selected the jlink core without option bytes
2018-03-06T16:16:48 < dongs> why is that even an option?
2018-03-06T16:17:12 < kaa> it's not good idea !bitmasked value

2018-03-06T17:52:16 < aandrew> that's not exactly rocket science
2018-03-06T17:53:07 < aandrew> take all the float values you want to use and multiply by 65536 for 16 bits of fractional resolution
2018-03-06T17:53:52 < kaa> it uses log too
2018-03-06T17:54:03 < emeryth> or just precalculate a lookup table
2018-03-06T17:54:06 < aandrew> do all your math in that area, remembering to shift things back down to maintain 16 bits of resolution. then peel out yoru final answer by dividing by 65536 and that's your integer part. subtract that(*65536) and multiply by 65536 for your fractional part
2018-03-06T17:54:22 < aandrew> emeryth: that alsow orks very well for thermisters
2018-03-06T17:54:34 < aandrew> and you can curve fit too if you want some additional accuracy
2018-03-06T17:54:43 < kaa> I do that usually to avoid using floats
2018-03-06T17:55:18 < aandrew> are you space constrained? because you won't be calculating this more than 10 times a second, softfloat is more than enough to not dick around iwth this unless you're just trying to be geeky

2018-03-06T18:45:56 < Laurenceb> hmm
2018-03-06T18:46:05 < Laurenceb> think I'll unplug it all and start again
2018-03-06T18:47:10 < PaulFertser> You can stop gpsd completely and use gpsctl in standalone fashion and try various things.
2018-03-06T18:48:24 < PaulFertser> You can also try gpsmon for that purpose, it has curses UI.
2018-03-06T18:48:38 < Laurenceb> ok
2018-03-06T18:48:46 < Laurenceb> well that failed anyway
2018-03-06T18:49:00 < Laurenceb> cant open /dev/ttyACM0
2018-03-06T18:49:11 < PaulFertser> gpsd stopped? sudo?
2018-03-06T18:49:24 < Laurenceb> its systemd
2018-03-06T18:49:30 < Laurenceb> cant see it in processes
2018-03-06T18:50:46 < Laurenceb> ok stopped it
2018-03-06T18:50:57 < Laurenceb> gpsctl seems to be less misbehaved now
2018-03-06T18:51:09 < Laurenceb> managed to enable ubx alongside nmea
2018-03-06T18:51:22 < BrainDamage> acm0 is the generic serial, make sure it's the actual file, generally a symlink is created giving you the access rights
2018-03-06T18:51:24 < Laurenceb> disable nmea still fails
2018-03-06T18:52:22 < Laurenceb> hmm I dunno
2018-03-06T18:52:35 < Laurenceb> cant make sense of this shit
2018-03-06T18:52:52 < Laurenceb> looks like I need to roll an stm32 interface board lol
2018-03-06T18:52:59 < Laurenceb> embedded lunix, not even once
2018-03-06T18:53:11 < PaulFertser> Will you parse ubx on stm32?
2018-03-06T18:53:19 < Laurenceb> yes

2018-03-06T18:54:36 < Laurenceb> wtf now its back to nmea

2018-03-06T18:55:00 < Laurenceb> I know I'll write a fail script and email it to ESR

2018-03-06T22:30:24 < Lux> if it has a persistent config that is
2018-03-06T22:31:05 < Laurenceb> it has ram
2018-03-06T22:31:11 < Laurenceb> so needs reconfigure all the time
2018-03-06T22:32:24 < Lux> you could run gpsctl as root
2018-03-06T22:32:38 < Lux> at least you won't get permission errors that way
2018-03-06T22:32:48 < Lux> but def not production ready :)
2018-03-06T22:33:29 < Lux> more like a fuck it solution
2018-03-06T22:35:43 < Steffanx> i hardly use my mac anymore crt.

2018-03-06T22:36:11 < Steffanx> no a drugs trip but a plane or train trip
2018-03-06T22:36:25 < Steffanx> *not
2018-03-06T22:36:37 < Lux> Laurenceb: and you probably shouldn't run gpsd before gpsctl
2018-03-06T22:36:50 < Steffanx> idk what you guys do crt, but us dutchies dont do such thing
2018-03-06T22:36:53 < Lux> rather first configure with gpsctl then start gpsd
2018-03-06T22:37:19 < Steffanx> iirc crt had a mac too once
2018-03-06T22:38:41 < PaulFertser> Lux: if gpsd was working properly it would auto-detect ubx availability and switched to it automatically. If it doesn't work that way, then it's a bug.
2018-03-06T22:39:12 < PaulFertser> And then gpsctl via control socket should be able to reconfigure it to faster sample rate etc.

2018-03-06T23:19:33 < Rob235> thats the cool part about living in europe, I'm sure its not as easy as it used to be but traveling between countries didn't take days.  so lonely over here in the US :/

2018-03-06T23:21:04 < Steffanx> We're the United States of Europe anyway.
2018-03-06T23:21:06 < Rob235> yea, theres no border between states, just signs that say thanks for visiting and welcome to
2018-03-06T23:21:22 < Rob235> but europe has to be more diverse than the US
2018-03-06T23:21:48 < englishman> .ro is not yurop

2018-03-06T23:22:01 < englishman> but they are separated by .eu
2018-03-06T23:22:01 < Steffanx> .ro is europe.
2018-03-06T23:22:06 < englishman> i disagree

2018-03-06T23:23:16 < Rob235> why, do grains not grow in the mountains? :)
2018-03-06T23:23:26 < englishman> only edelweiss
2018-03-06T23:23:30 < Tectu> Rob235, because we're all busy printing at the library
2018-03-06T23:23:46 < Steffanx> FYI swisserland has the highest bigmac index on earth
2018-03-06T23:23:55 < Steffanx> You wouldnt survive that Rob235.
2018-03-06T23:24:20 < englishman> tectu its like 310eur round trip
2018-03-06T23:24:21 < Steffanx> I would even dare to say the highest of the entire universe.
2018-03-06T23:24:32 < englishman> il show you how to buy my tix
2018-03-06T23:24:33 < Steffanx> I cant even get to swisserland and back for 310 euro
2018-03-06T23:24:43 < englishman> wat
2018-03-06T23:24:48 < Steffanx> Yes.
2018-03-06T23:25:11 < Steffanx> https://en.wikipedia.org/wiki/Big_Mac_Index crt
2018-03-06T23:25:15 < Tectu> jpa- pays
2018-03-06T23:25:59 < zyp> 275eur round trip for me if I drive up to oslo and fly from there
2018-03-06T23:26:02 < Rob235> I want to visit Tectu and Steffanx, tectu, you dont have to be there when I do though...
2018-03-06T23:26:04 < Rob235> amsterdam sounds fun too
2018-03-06T23:26:12 < zyp> but I've already got plans for next weekend
2018-03-06T23:26:26 < Steffanx> no amsterdam is boring.
2018-03-06T23:26:26 < Rob235> my bday is in a week, who wants to buy me things
2018-03-06T23:26:31 < Tectu> amsterdam is very boring, Rob235
2018-03-06T23:26:34 < englishman> https://www.google.nl/flights/#search;f=AMS,ZYA;t=ZRH,ZLP;d=2018-04-11;r=2018-04-18
2018-03-06T23:26:35 < jadew> I found some ok flights too, but not to Bern
2018-03-06T23:26:37 < Rob235> how can it be?
2018-03-06T23:26:38 < englishman> 64eur
2018-03-06T23:26:42 < Tectu> zyp, we might do a 2nd one then
2018-03-06T23:26:50 < Rob235> is that why drugs are legal? only way to combat the boredom?
2018-03-06T23:26:51 < englishman> zyp, its not next weekend, its april
2018-03-06T23:26:54 < jadew> flying to Bern (which I understand is the closest) would be 1600 eur on such a short notice
2018-03-06T23:26:55 < Tectu> jadew, don't fly to bern. fly to zurich, basel or geneva
2018-03-06T23:27:02 < Steffanx> lies englishman.
2018-03-06T23:27:12 < englishman> oh shit
2018-03-06T23:27:15 < Rob235> dont tempt me crt
2018-03-06T23:27:15 < Tectu> englishman don't screw with the timezones
2018-03-06T23:27:16 < englishman> did he say march
2018-03-06T23:27:19 < englishman> rip
2018-03-06T23:27:39 < Steffanx> still only 117 :P
2018-03-06T23:28:54 < jadew> cheapest I found is 165, but takes 16 hours
2018-03-06T23:29:00 < Steffanx> WUT?
2018-03-06T23:29:05 < Tectu> o.O
2018-03-06T23:29:05 < englishman> maybe the bridge will be built by then
2018-03-06T23:29:07 < jadew> 215 would be more reasonable
2018-03-06T23:29:09 < jadew> at 5h
2018-03-06T23:30:11 < jadew> a direct flight would only take 2 hours
2018-03-06T23:30:21 < jadew> but only found one option like that
2018-03-06T23:30:46 < Rob235> lets see, from me to zurich is $2200 USD and 11 hours
2018-03-06T23:31:56 < upgrdman> 2hr flight? so ~8hr drive?
2018-03-06T23:32:05 < Rob235> $775 from tap air portugal whatever airline that is
2018-03-06T23:32:05 < jadew> yeah, probably
2018-03-06T23:32:16 < upgrdman> oh that's right. europe. driving would be a pain in the ass.
2018-03-06T23:32:33 < jadew> it's not that bad
2018-03-06T23:32:49 < jadew> may take more than 8 hours tho
2018-03-06T23:32:54 < Rob235> what is the most 'tropical' place in europe? spain?
2018-03-06T23:32:58 < ds2> upgrdman, were you the one playing with small induction heaters?

2018-03-06T23:33:59 < englishman> cool
2018-03-06T23:34:01 < englishman> for annealing?
2018-03-06T23:34:07 < upgrdman> no, for fucking around
2018-03-06T23:34:10 < englishman> heh
2018-03-06T23:34:13 < upgrdman> i have no real use cases for it
2018-03-06T23:34:26 < ds2> upgrdman: are they enough to do simple things (i.e. melt a 1 cm^3 chunk of metal in a copper/steel tube)

2018-03-07T00:36:11 < upgrdman> hmmm wtf didn't i use the ternary operator. oh well.
2018-03-07T00:36:28 < catphish> i feel like that could be somewhat optimized, but might do the same
2018-03-07T00:38:32 < upgrdman> ya i feel like if i thought about it longer i could make a branchless version that is O(1)

2018-03-07T00:42:20 < upgrdman> also if you want speed, i'd unroll the loop
2018-03-07T00:42:52 < upgrdman> or use some #pragma to unroll it

2018-03-07T01:13:10 < upgrdman> you almost definitely want to spring load your pen holder
2018-03-07T01:13:19 < upgrdman> so you can get ~consistent pressure on the nib

2018-03-07T09:37:23 < zyp> yeah, internal MAC in stm32 can't do ethercat slave
2018-03-07T09:39:35 < zyp> ethercat is this ring stuff where a master sends out one frame with a bunch of fields defined for various slaves, and then each slave rewrites their part of the frame as it passes through, and then at the end of the ring master receives back the modified frame with fields for all slaves filled in
2018-03-07T09:40:06 < zyp> master just sends and receives, so a normal MAC can implement a master, but the slaves all need rewrite capability

2018-03-07T10:21:40 < dongs> The GPIOs’ reset state is not guaranteed during the powerup phase. During this phase, the GPIOs are in input pullup mode
2018-03-07T10:21:43 < dongs> and they take their reset value only after VDDCORE POR reset has been released. If a GPIO must be at level zero at powerup,
2018-03-07T10:21:47 < dongs> it is recommended to connect an external pulldown to guarantee this state.

2018-03-07T13:59:11 < karlp> tomeaton17: you're not meant to be asking those questions, you meant to be just using hal.
2018-03-07T14:02:09 < tomeaton17> My current approach to receive different number of bytes each time is to just receive say 100 and when idle line is detected abort dma transfer. Don't know if this will work with a shared handler as could potentially mess up tx

2018-03-07T15:33:35 < tct> sexytimes for Steffanx
2018-03-07T15:34:09 < Steffanx> Tilburg is on the otherside of the globe for me
2018-03-07T15:34:14 < karlp> only flight I foudn to zurich that doesnt' include an overnight in london is ~6 hours our, and ~9 hours home
2018-03-07T15:34:28 < tct> worth
2018-03-07T15:37:04 < Steffanx> Awh.
2018-03-07T15:39:59 < englishman> how do you guys live in such a tiny place and have so much trouble getting around
2018-03-07T15:40:31 < Steffanx> Its a mental issue englishman
2018-03-07T15:40:39 < Steffanx> Aaand its busy on the roads
2018-03-07T15:40:59 < englishman> pretty sure my driveway is almost as big as your country
2018-03-07T15:41:32 < Steffanx> How big is your driveway?
2018-03-07T15:41:51 < englishman> well there is not much traffic on it
2018-03-07T15:47:12 < karlp> my rock might be small, but there's a lot of sea around it.
2018-03-07T15:51:00 < srk> Laurenceb: you can create udev rules to have stable names instead of different ACM{X} each time something locked the previous one
2018-03-07T15:53:50 < karlp> or just use /dev/serial/by-id or /dev/serial/by-path
2018-03-07T15:53:55 < karlp> and not have to worry about it.
2018-03-07T15:54:43 < karlp> depending on whether you want to be stable by physical port or by device.
2018-03-07T15:57:07 < Laurenceb> yeah I know
2018-03-07T15:57:12 < Laurenceb> but thats not the issue here
2018-03-07T15:57:18 < Laurenceb> I have an idea actually
2018-03-07T15:57:24 < Laurenceb> maybe its how gpsd is launched
2018-03-07T16:00:00 < karlp> people have been using gpds for fucking years
2018-03-07T16:00:08 < karlp> why do yu have such epic problems withe verything

2018-03-07T17:33:45 < Laurenceb> LeoBodnar does
2018-03-07T17:33:54 < Laurenceb> but isnt here...
2018-03-07T17:34:01 < Laurenceb> absolute timing or jitter?
2018-03-07T17:34:54 < Laurenceb> aiui he didnt look much at absolute timing, but jitter is v low whatever the output pps rate
2018-03-07T17:35:12 < Laurenceb> looked like there was a pll connected to pps pin
2018-03-07T17:36:02 < Laurenceb> but some frequencies were better, iirc he used 10khz output or something
2018-03-07T17:36:27 < Laurenceb> oh he looked at absolute with ntp
2018-03-07T17:36:52 < Laurenceb> down to tens of ns iirc
2018-03-07T17:37:07 < Laurenceb> but that included error from the whole system

2018-03-07T17:40:12 < karlp> you'll have more errors from how you do the zero crossing detection to get the mains tiemstamps than from the time source won't you?

2018-03-07T17:43:11 < qyx> I mean clocks synced to the 50Hz mains freq are 5 minutes late
2018-03-07T17:43:15 < sync> yes

2018-03-07T18:43:15 < PaulFertser> Laurenceb's too smart. gpsd is designed specifically to suit the needs of "Aunt Tilly" y'know.
2018-03-07T18:43:38 < karlp> qyx: this is freeboard.io
2018-03-07T18:43:40 < Laurenceb> there is some sort of probe shit
2018-03-07T18:43:53 < Laurenceb> that runs every minute or so, but only when it has a lock
2018-03-07T18:43:55 < Laurenceb> weird

2018-03-07T18:46:26 < oz4ga> About a monht ago someone, karlp if I remember correctly, talked about NetBeans as a good cross platform IDE. Looking at their page it seems like debugging of embeded is stil a beta feature. Anyone who would care to comment on this?
2018-03-07T18:47:08 < karlp> I've been using it for years, the gdbserver plugin talks happily to openocd, it "just works"
2018-03-07T18:47:38 < karlp> here's the most recent time I wrote it about it http://false.ekta.is/2016/01/using-netbeans-for-stm32-development-with-openocd/
2018-03-07T18:48:04 < oz4ga> excelent.Thank you.
2018-03-07T18:49:08 < karlp> these days of course, you can just use atollic....
2018-03-07T18:49:17 < Laurenceb> its working for now....
2018-03-07T18:49:19 < karlp> I've not tried it since it became free, only got as far as downloading it so far
2018-03-07T18:52:14 < Laurenceb> oh wow
2018-03-07T18:52:20 < Laurenceb> now its totally dead
2018-03-07T18:52:22 < Laurenceb> way to go gpsd
2018-03-07T18:54:04 < oz4ga> karlp: same here. I downloaded it. Did a snapshot tried to install and then rolled back. I saw it starting up etc.
2018-03-07T18:58:01 < oz4ga> The netbeans thing was due to someone during a discussion about cross-platform IDEs tried to harpoon the idea of NetBeans by quoting, that the netbeans doc sayz that the plugin for embeded. Just wanted to ask someone who had tried it them selfs.
2018-03-07T18:58:11 < oz4ga> bbl. Dinner.
2018-03-07T19:03:31 < Laurenceb> hmm looks like gpsd is unusable
2018-03-07T19:03:40 < Laurenceb> it needs nmea input enabled
2018-03-07T19:03:50 < Laurenceb> and uses that to periodically soft reset the gps

2018-03-07T19:41:19 < Rob235> ugh... my dumbass gf is skipping anger management because shes angry...
2018-03-07T19:46:04 < zyp> why are you complaining about your gf?
2018-03-07T19:46:15 < zyp> you chose her, if you're not happy with her, that's on you
2018-03-07T19:46:31 < Steffanx> zyp never complains about his wife?
2018-03-07T19:46:48 < zyp> that would be admitting I made a mistake :p
2018-03-07T19:48:26 < Steffanx> Important question Rob235: is she angry with you..
2018-03-07T19:48:44 < Rob235> of course
2018-03-07T19:48:54 < Steffanx> Better fix it instead then
2018-03-07T19:48:55 < Rob235> even if shes angry with herself she turns it on me
2018-03-07T19:49:03 < Rob235> fuck it, it wasn't my fault, shes just insane

2018-03-07T23:17:33 < upgrdman> god damn it. some software a coworker wrote displays a bunch of bytes in hex. except he didnt format them so each byte always takes up two places. like instead of printf("%02X") he did "%X" ... so shit like 80 08 8A is displayed as 0x8088A ... wtf

2018-03-07T23:18:04 < upgrdman> ya

2018-03-07T23:18:31 < upgrdman> very funtimes :/
2018-03-07T23:18:35 < BrainDamage> time to write a shit script in a esoteric language to fix the problem client side
2018-03-07T23:18:56 < BrainDamage> or you know, fix the problem at the source
2018-03-07T23:19:34 < upgrdman> "luckily" it's an internal tool, so no client side
2018-03-07T23:19:45 < upgrdman> just need to bitch at my coworker
2018-03-07T23:20:21 < upgrdman> also, *zero* error checking. like you can remove things from a list, and if you dont select something to remove it just pops up a window showing a stacktrace. lolz
2018-03-07T23:20:43 < upgrdman> at least it pops up a window instead of just printing to stdout
2018-03-07T23:20:55 < BrainDamage> error checking is like safety labels
2018-03-07T23:25:21 < karlp> at least you get the stacktrace :)

2018-03-08T09:52:02 < qyx> and also it probably doesn't matter for short runs
2018-03-08T09:54:33 < qyx> also it looks like RG174 has the lowest attenuation at 1GHz (from these three)

2018-03-08T10:08:42 < dongs> pro answer
2018-03-08T10:09:18 < Ultrasauce> ya just add the files together
2018-03-08T10:09:25 < dongs> Ultrasauce: uh, doesnt quite work like that
2018-03-08T10:11:22 < Ultrasauce> isnt the hex format just a set of addresses and data to write to them?
2018-03-08T10:11:30 < Ultrasauce> nothing stateful
2018-03-08T10:12:40 < dongs> there's the short header at start
2018-03-08T10:12:45 < dongs> :020000040800F2
2018-03-08T10:12:47 < dongs>  or whatever
2018-03-08T10:13:11 < Ultrasauce> ok thats the base address but the one in the second file will supersede it correctly
2018-03-08T10:13:31 < dongs> they're actualyl same
2018-03-08T10:13:43 < dongs> er im lokin at wrong start one
2018-03-08T10:13:59 < dongs> i need to reboot my fucking desktop
2018-03-08T10:14:09 < dongs> explore windows take 10 seconds to change up/down folder
2018-03-08T10:14:16 < dongs> thanks, windows dickfender
2018-03-08T10:14:17 < Ultrasauce> if you ran linux you wouldn't need to reboot
2018-03-08T10:14:24 < Ultrasauce> and im sure this functionality is built into binutils
2018-03-08T10:14:26 < dongs> i also wouldn't be able to do shit
2018-03-08T10:14:53 < kakimir> what are cores made of in current transformers?
2018-03-08T10:15:53 < dongs> actualyl yeah Ultrasauce that header is same in both bootloader and userspace hex
2018-03-08T10:16:08 < Ultrasauce> it's just the base address and will likely be the same as long as your flass is <64k
2018-03-08T10:16:12 < Ultrasauce> flash
2018-03-08T10:16:46 < zyp> can probably do some shit with objcopy
2018-03-08T10:17:03 < dongs> i mean, i could just use the tools linked from keil.com
2018-03-08T10:17:04 < dongs> and be done
2018-03-08T10:17:07 < Ultrasauce> it wouldn't matter if they were different anyway. all you gotta do is remove the end of file marker from the first and catenate them together
2018-03-08T10:17:20 < dongs> yeah, too much work. when i can just write a script to do it
2018-03-08T10:17:52 < dongs> anyway, i asked the other day how ROP works with custom bootloaer and the answer it, it just works
2018-03-08T10:18:11 < dongs> i flashed both, enabled ROP, booted to bootloader and updated
2018-03-08T10:18:14 < zyp> ah, yeah, I were gonna answer that, but I got distracted and forgot
2018-03-08T10:18:17 < dongs> everything works fine
2018-03-08T10:18:44 < zyp> the way ROP works is that as long as debugger is not connected, everything works as normal
2018-03-08T10:18:53 < dongs> yeah, so it seems
2018-03-08T10:18:58 < zyp> as soon as you connect the debugger, it kills the flash interface, so nothing works
2018-03-08T10:19:01 < dongs> sure sounds like its abusable tho
2018-03-08T10:19:09 < dongs> like, you could buffer overflow some shit in userspace
2018-03-08T10:19:14 < zyp> yes
2018-03-08T10:19:17 < zyp> absolutely
2018-03-08T10:19:18 < dongs> and use it to leech both fw and bootloader
2018-03-08T10:20:14 < zyp> trick is to prevent exploits like that
2018-03-08T10:20:33 < zyp> first, don't write shitty code
2018-03-08T10:20:52 < zyp> second, use MPU to make everything but .text NX
2018-03-08T10:20:53 < dongs> brb posting my project on freecancer to MISRA-C-ify it
2018-03-08T10:21:17 < zyp> cortex-m MPU can enforce NX, right?

2018-03-08T10:21:32 < Ultrasauce> seems to me it was m4 only
2018-03-08T10:21:36 < dongs> im not sure, this stuff isnt that critical. if I couldnt figure out how to make ROP work with bootloader I was just gonna not care about ti
2018-03-08T10:21:59 < dongs> but since it works without any changes thats about as much time as i wanna spend on it
2018-03-08T10:22:34 < Ultrasauce> as with most security things you're not gonna get it bulletproof but not being low hanging fruit is a good start
2018-03-08T10:22:42 < dongs> ya
2018-03-08T10:23:04 < zyp> also harder to find buffer overflows when you don't have the code
2018-03-08T10:28:18 < dongs> wtf that shitrec_cat thing is spamming errors and produce nothing of value

2018-03-08T10:35:25 < tct> hi
2018-03-08T10:35:47 < dongs> now i need to figure out how to  make that fucking thing output same width hex data
2018-03-08T10:36:03 < dongs> it takes 16byte hex records and without asking me changes to 32byte
2018-03-08T10:36:42 < Ultrasauce> this is definitely a job for the dumbest possible solution
2018-03-08T10:36:55 < dongs> ya?
2018-03-08T10:37:05 < Ultrasauce> ie catting the two files together and deleting the first eof

2018-03-08T10:37:28 < dongs> Ultrasauce: lol, its fine, srec shit will wokr
2018-03-08T10:37:38 < dongs> im not gonna manualyl edit any files for this
2018-03-08T10:37:44 < dongs> or manually copypaste shit
2018-03-08T10:38:11 < Ultrasauce> what happened to scripting it
2018-03-08T10:38:17 < dongs> thats what im doing
2018-03-08T10:38:24 < dongs> once i figure out the correct mile-long command lines
2018-03-08T10:38:26 < dongs> for the script
2018-03-08T10:46:09 < Ultrasauce> check out the source for that tool
2018-03-08T10:46:15 < Ultrasauce> it's pretty good
2018-03-08T10:46:28 < dongs> sarcasm or legit
2018-03-08T10:46:40 < Ultrasauce> good as in i am thoroughly enjoying reading it

2018-03-08T13:42:04 < zyp> I did firmware once on a board using one of those
2018-03-08T13:43:28 < zyp> still needs tuning/impedance matching to be optimal
2018-03-08T13:44:21 < zyp> reason is antenna works relative to the ground plane on your board, and with a relatively small ground plane (wrt. wavelength), the shape of the ground plane is also significant
2018-03-08T13:55:43 < qyx> I was reading about fractal antennas the other day
2018-03-08T13:55:50 < qyx> found out they are basically bullshit

2018-03-08T14:01:05 < karlp> qyx: bullshit because shit just radiates anywya, because everythign's an antenna?
2018-03-08T14:01:25 < karlp> do the y have big claims on perf for thos e funky designs, that are often just not backed up?
2018-03-08T14:02:13 < qyx> because shit radiates comparably to a simpler pcb antenna
2018-03-08T14:02:19 < qyx> so no reason to fractalize it

2018-03-08T15:55:29 < dongs> Arxan Defense Systems was a leading provider of anti-tamper solutions to the federal market. Its hardware and software approach to anti-tamper enables the U.S. government to fortify and protect its most critical program information.
2018-03-08T15:55:52 < qyx> high-voltage active anti-tamper
2018-03-08T15:56:09 < qyx> stm32 should have such pin
2018-03-08T15:56:12 < dongs> haha
2018-03-08T15:56:23 < qyx> besides the tamper-detection one
2018-03-08T15:56:53 < dongs> does it output 300V on the pin?
2018-03-08T15:57:07 < qyx> idk, just trolling

2018-03-09T13:33:32 < jpa-> i've always been confused by the difference between framed vs. non-framed stencils
2018-03-09T13:34:07 < karlp> just like a screen print mask
2018-03-09T13:34:28 < karlp> you can get just the screen, but if you have a machine that takes frames and holds them down you want framed unless you want to frame it yourself
2018-03-09T13:34:38 < jpa-> more like, which one do i want if the cost is the same and i have no special machines?
2018-03-09T13:34:50 < karlp> if you're just going to use stickytape on your desk to hold the stencil down you don't need a frame
2018-03-09T13:35:37 < jpa-> i don't know what i'll be using, but which one will be easier?

2018-03-09T13:35:50 < jpa-> yeah :P
2018-03-09T13:35:54 < jpa-> it seems the frame might either help or be annoying
2018-03-09T13:44:48 < zyp> I've never used a framed stencil
2018-03-09T13:45:00 < zyp> but I've never seen them at the same price point as unframed ones either
2018-03-09T13:52:18 < dongs> jpa-: if cost is same you definitely want framed
2018-03-09T13:52:28 < dongs> flimsy non-stretched stencils = MAKE:R failure
2018-03-09T14:01:51 < karlp> non-stretched? were talking steel ones here right?
2018-03-09T14:01:56 < dongs> yeah
2018-03-09T14:02:02 < dongs> plastic shit is a nonstarter
2018-03-09T14:02:20 < dongs> metal needs to be stretched to be useful, too
2018-03-09T14:03:33 < karlp> "stretched" ?
2018-03-09T14:03:38 < dongs> yes
2018-03-09T14:03:39 < karlp> or just "actually held down flat"
2018-03-09T14:03:40 < dongs> what teh frame does
2018-03-09T14:03:46 < dongs> yeah, wahtever it is

2018-03-09T14:07:24 < jpa-> jlcpcb seems to have about the same prices (around $10) from framed / non-framed, but the shipping cost will of course be a bit higher
2018-03-09T14:10:12 < karlp> bit/lot
2018-03-09T14:12:50 < dongs> you can have them framed in pretty small stuff
2018-03-09T14:13:03 < dongs> or be awesome like me and have a pneumatic frame / machien for stenciling non-framed ones
2018-03-09T14:13:09 < dongs> shit's awesome

2018-03-09T14:46:40 < zyp> aww
2018-03-09T14:47:06 < zyp> btw, I wanna pay you for stuff
2018-03-09T14:49:31 < dongs> just noticed aandrew's 32khz osc PDF says applications: PC SEVER
2018-03-09T14:49:43 < zyp> heh
2018-03-09T14:50:30 < dongs> all products are backed by Microchip’s customer-driven obsolescence policy which ensures availability for as long as needed.
2018-03-09T14:50:55 < zyp> dongs, according to my notes I owe you $360 for PCBA for previous LL batch, plus whatever PCB+PCBA for this batch is
2018-03-09T14:51:17 < dongs> ok, that works. i would need to figure out what this months work is
2018-03-09T14:51:22 < dongs> are you sure you didn't pay the previous LL?
2018-03-09T14:51:36 < dongs> previous is like months back?
2018-03-09T14:51:39 < zyp> I paid parts and pcb for previous, but not assembly
2018-03-09T14:51:46 < zyp> and yeah, previous was about a year ago
2018-03-09T14:51:53 < dongs> ah ok, that sounds familiar
2018-03-09T14:52:06 < dongs> right, cuz you jus paid chinagirl for parts last time as well
2018-03-09T14:52:17 < zyp> and I've paid parts for this batch, but not pcb and assembly
2018-03-09T14:52:40 < dongs> anyway, after this one I counted all the shit up and bagged it and printed out remaining stock list, so plz make more less than a year from now :D
2018-03-09T14:53:02 < dongs> zyps crap box is nicely organized
2018-03-09T14:53:08 < zyp> also, if you prefer over paypal, I can do jpy furikomi now
2018-03-09T14:53:13 < zyp> haha, nice
2018-03-09T14:53:25 < dongs> you scammed a jap account somehow?
2018-03-09T14:54:30 < dongs> anyway i donno wat the amounts are, will ned to look at paperwork adn shit, so it will be a while before I know final numbers
2018-03-09T14:55:51 < zyp> ya, my wife has one
2018-03-09T14:57:03 < tomeaton17> keil chaps https://gyazo.com/324b5a18690de916af614f5bbb48ce52 I just got this error never had it before, havent changed the file its complaining about. Any ideas
2018-03-09T14:59:34 < dongs> thats not a keil error
2018-03-09T14:59:40 < dongs> you did change the file, maybe by mistake/something
2018-03-09T14:59:57 < dongs> goto pack manager, delete and redownlaod f0 pack
2018-03-09T15:00:18 < dongs> i mean just looking at that sores line should be clear what ytou fucked up
2018-03-09T15:02:47 < zyp> I bet you did something like #define RESET, fucking up other stuff using the same name
2018-03-09T15:05:23 < jpa-> or forgot some } in some header it is including
2018-03-09T15:05:35 < dongs> those hal shits only include its own stuff
2018-03-09T15:05:39 < dongs> shouldn't be any user headers
2018-03-09T15:06:16 < dongs> keil text editor has this gay thing where if you press alt-<some letter> too fast after compiling (like to flash/debug) it will insert some unicode ? mark into whatever file is currently open
2018-03-09T15:06:23 < jpa-> stm32f0xx_hal_conf.h  maybe?
2018-03-09T15:06:36 < dongs> ah thats possible, tho there's not much user-editable in that one either
2018-03-09T15:06:44 < dongs> its mostly just boilerplate shit

2018-03-09T15:23:08 < jpa-> strangest is that it seems to be rather new part
2018-03-09T15:23:51 < jpa-> https://i.ytimg.com/vi/IRl7dZzRoAQ/maxresdefault.jpg   these are common enough but nowadays i'd just use a microcontroller
2018-03-09T15:24:14 < dongs> but would it be $0.40
2018-03-09T15:25:25 < BrainDamage> I've used a similar shit in high school for a project, but it was a single line driver for intensity vs whole spectrum
2018-03-09T15:26:41 < jadew> would a cheap MCU be able to do that fast enough?
2018-03-09T15:27:03 < BrainDamage> if you use goertzel's algo instead of fft: yes
2018-03-09T15:27:04 < jadew> I mean, you'd have to do FFT
2018-03-09T15:28:02 < jadew> that looks useful
2018-03-09T15:28:37 < jadew> that IC is probably just filtering the signal, no?
2018-03-09T15:28:56 < dongs> i wanna see a video of it doing something
2018-03-09T15:29:19 < BrainDamage> probably a bunch of crossover filters from switched caps in bucket brigade then flash comparators
2018-03-09T15:30:17 < BrainDamage> it's not like it has to be accurate

2018-03-09T16:45:02 < dongs> i donno but last ~3 micrel things i looked up on digikey were all non-stock
2018-03-09T16:45:38 < dongs> i guess its in stock at mouser as well as at microshit's own store so its not that big of a deal
2018-03-09T16:46:43 < dongs> oh moq @ microchip shop is 500/5000 pcs

2018-03-09T18:48:10 < tomeaton17> Yeah as an intern I definitely dont get paid enough to get it working without floats lol
2018-03-09T18:49:08 < karlp> Thorn: there's some notes in zypsnips on it.
2018-03-09T18:49:45 < Rob235> you can use mosfets in parallel?
2018-03-09T18:53:35 < sync> yes, but some things need to be observed to do it properly
2018-03-09T18:54:12 < Rob235> how would I do it with 30N06L for my printers heatbed? :)
2018-03-09T18:55:11 < Rob235> I read mosfets have a kind of natural load balancing with temperature

2018-03-09T19:02:00 < Thorn> the connector is still twice as expensive as the phy :/
2018-03-09T19:02:42 < Cracki> use a beefier mosfet?
2018-03-09T19:03:40 < Cracki> the  30N06L has tolerable rdson. what volts and amps do you need?
2018-03-09T19:04:49 < Cracki> and what gate voltage? it's labeled as logic level, but at 3.3v it appears to conduct around 10 amps
2018-03-09T19:05:00 < Cracki> 10-20

2018-03-09T19:13:01 < Cracki> what's the goal? more heating in the bed? less heating the mosfet?
2018-03-09T19:13:24 < Rob235> I just want to take the current off the mainboard
2018-03-09T19:13:28 < Cracki> uh?
2018-03-09T19:13:33 < Cracki> explain
2018-03-09T19:14:09 < Rob235> do you have a 3d printer? mosfets for controlling the heated bed and hot end are very common. I believe the main purpose is to avoid the current being drawn from the mainboard and straight from the power supply
2018-03-09T19:15:34 < Cracki> no, mosfets are transistors. you use them to PWM the current, so regulate power

2018-03-09T19:16:38 < Rob235> ? they are used like switches, turned on and off with logic level gate voltage
2018-03-09T19:16:54 < Cracki> yes
2018-03-09T19:18:16 < Cracki> these "upgrades" seem to take the on-board heating power output as logic instead...
2018-03-09T19:18:47 < Thorn> soyuz launch https://www.youtube.com/watch?v=MTp2n0qsAEc
2018-03-09T19:18:49 < Rob235> thats what I said
2018-03-09T19:18:53 < Thorn> T+7 already
2018-03-09T19:19:00 < Cracki> that can be ok as long as you take care to connect to common ground
2018-03-09T19:20:30 < Rob235> my question was just about the specific mosfets that I have, if they are enough with just a small copper heatsink or if I should parallel them
2018-03-09T19:21:12 < Cracki> hm, depends on the current needed to heat up and maintain the bed
2018-03-09T19:21:46 < Cracki> the mosfet datasheet you posted should be ok, but there are ones with lower Rdson
2018-03-09T19:21:48 < Rob235> the psu is only 20A and these are rated for 32A but I saw on a post that they get too warm or something so I just didn't understand what I should do
2018-03-09T19:21:59 < Rob235> I have a bag of them so I dont mind using multiple
2018-03-09T19:23:19 < Cracki> yes, parallel them if they get too hot. this can affect the pwm duty cycle (same dc but more efficient)
2018-03-09T19:23:37 < Rob235> and I've seen some with an optoisolator, not sure if that is necessary?
2018-03-09T19:23:49 < Cracki> prolly not. you have common ground everywhere.
2018-03-09T19:23:57 < Rob235> ok sounds good, thanks
2018-03-09T19:24:16 < Cracki> you need that only if logic and power supplies have no common ground
2018-03-09T19:24:25 < Rob235> I see
2018-03-09T19:30:38 < Lux> Rob235: just put a few in parallel no worries there
2018-03-09T19:30:48 < Rob235> ok nice
2018-03-09T19:30:57 < Lux> with 3d printers the pwm speed is so low you don't need to worry
2018-03-09T19:31:27 < Lux> and you can easily calculate the power on the mosfet with I^2 * Rdson
2018-03-09T19:33:34 < Rob235> how do you get the current, you have to measure it? I'm assuming it will be about 2-3W from what I've read
2018-03-09T19:33:53 < Lux> depends on your heatbed
2018-03-09T19:34:10 < Rob235> yea, doubt I'll find the specs online, I guess I could just measure the resistance?
2018-03-09T19:34:11 < Lux> the cheap ones usually are around 100 watts so probably around 10 amps
2018-03-09T19:34:17 < Lux> sure
2018-03-09T19:34:35 < Lux> or put a clamp meter on the wire, but I guess you don't own one
2018-03-09T19:35:12 < Rob235> I have some kind of current meter that ive never used, not sure what it even is hah, let me see if I can find it
2018-03-09T19:35:25 < Rob235> a current shunt I believe?
2018-03-09T19:35:49 < Lux> that'll work too
2018-03-09T19:36:23 < Lux> but just put like 3-4 in parallel and you should be good
2018-03-09T19:36:59 < Rob235> ok sounds good, I'll try that out later
2018-03-09T19:39:29 < Lux> here is something to read up on: http://www.irf.com/technical-info/appnotes/an-941.pdf

2018-03-09T19:40:07 < Rob235> thx
2018-03-09T19:40:10 < Lux> but most of that stuff doesn't really matter, as the pwm frequency is in the sub 1khz range
2018-03-09T19:40:36 < Lux> i think it's even sub 100 hz
2018-03-09T19:44:06 < Cracki> you can measure the resistance of your heatbed with a meter
2018-03-09T19:44:15 < Cracki> then figure out what current at 12 volts you can push through that.
2018-03-09T19:44:21 < Rob235> right
2018-03-09T19:44:22 < Cracki> then look up the rdson for that current
2018-03-09T19:44:32 < Cracki> then calculate the power wasted in the mosfet
2018-03-09T19:44:54 < Cracki> r * i^2 or something like that. ohm's laws.
2018-03-09T19:45:12 < Rob235> I'm reading this right now which is pretty informative, its mostly what ive already picked up but I havent finished reading yet: https://toms3d.org/2016/01/11/guide-properly-picking-and-using-mosfets/
2018-03-09T19:45:42 < Cracki> consider: during heat-up, it'll prolly go full throttle
2018-03-09T19:46:03 < Cracki> and that's the max and it will be limited by heat bed resistance. the mosfet will be a tiny fraction of that R
2018-03-09T19:47:07 < Cracki> but still, if the mosfet dissipates just 1 watt, that'll heat it up quickly, if you just stand it up without any thermal connection to a ground plane or heat sink
2018-03-09T19:47:37 < Thorn> An errata sheet, describing minor operational differences from the data sheet and recommended workarounds, may exist for current devices.
2018-03-09T19:51:49 < tomeaton17> have a good weekend chaps
2018-03-09T20:10:56 < Steffanx> Same to you mr tomeaton17
2018-03-09T20:30:59 < Thorn> do you remove ground plane from under a rj-45 connector?
2018-03-09T20:31:27 < zyp> magjack or separate magnetics?
2018-03-09T20:31:40 < Thorn> integrated magjack
2018-03-09T20:31:48 < zyp> then there's no need
2018-03-09T20:31:59 < zyp> it's internally isolated
2018-03-09T20:32:51 < Thorn> what about the 2 pins connected to the metal case of the magjack? do I gnd them?
2018-03-09T20:33:01 < zyp> I think that's what I did
2018-03-09T20:33:34 < zyp> if you want to separate case ground and signal ground, you probably separate them
2018-03-09T20:34:58 < zyp> but as long as you're only doing UTP cabling, that's also irrelevant
2018-03-09T20:35:04 < Thorn> that is what SMSC is showing in their guidelines (but only for separate connector & magnetics) but I'm not going to have a metal case/chassis
2018-03-09T20:35:29 < zyp> then it doesn't matter
2018-03-09T20:36:37 < zyp> with separate magnetics you want to maintain 2kV isolation or something like that between the line signals and the rest of your stuff
2018-03-09T20:37:03 < zyp> which is why you keep the ground plane away from the area between the magnetics and the connector
2018-03-09T20:37:24 < zyp> but with a magjack, all that is taken care of inside the jack
2018-03-09T20:43:15 < Thorn> yeah I thought the 2kV rule also applied to integrated jacks

2018-03-09T22:22:39 < Cracki> Rob235, ...
2018-03-09T22:22:41 < Cracki> reading...
2018-03-09T22:23:02 < Cracki> get rid of the resistors between D0 and the gates.
2018-03-09T22:23:09 < Cracki> the pulldowns are a good idea however.
2018-03-09T22:23:32 < Cracki> you can make them larger. they're only relevant as long as the arduino doesn't drive the pin either way.
2018-03-09T22:23:41 < Rob235> right
2018-03-09T22:23:58 < Cracki> also perhaps rearrange the schematic a little. lines are crossing that need not
2018-03-09T22:24:08 < Cracki> but this should be good
2018-03-09T22:24:24 < Rob235> ok, yea I dont really care about the schematic, just wanted to make sure I did it right
2018-03-09T22:24:48 < Cracki> resistors between D0 and gates only prolong the time to charge the gates
2018-03-09T22:24:51 < Rob235> I mean, I used a pressure sensitive resistor as the heated bed so.. :)
2018-03-09T22:25:00 < Cracki> it's a squiggly line, good enough
2018-03-09T22:25:08 < Rob235> yup
2018-03-09T22:25:55 < Cracki> ya, pulldowns can easily be 10x the resistance.
2018-03-09T22:26:22 < Cracki> as is, they'd collectively pull 2 mA.
2018-03-09T22:35:55 < Thorn> how do you manage to read these kinds of schematics
2018-03-09T22:36:12 < Thorn> I need ground (and mosfet sources) on the bottom, power on the top
2018-03-09T22:36:14 < Thorn> etc.
2018-03-09T22:37:38 < englishman> and gates either right or left
2018-03-09T22:38:08 < Thorn> some textbook said that good circuit designers have geometric thinking
2018-03-09T22:39:53 < Thorn> also I've no idea if 4 mosfet gates is too much capacitance for an "arduino" pin to drive
2018-03-09T22:40:21 < Cracki> eh it'll be fine
2018-03-09T22:40:39 < Rob235> ive never made a schematic btw, quit yer bitching :P
2018-03-09T22:40:48 < Cracki> read the sheet, find the gate capacitance, calculate with 10 mA from the pin, you'll see it's ok
2018-03-09T22:40:50 < Rob235> its not like I went to school for this
2018-03-09T22:41:05 < Cracki> look for coulombs or farads
2018-03-09T22:43:14 < Thorn> is it going to be pwm'd?
2018-03-09T22:44:06 < englishman> usually they are fine with bang-bang
2018-03-09T22:44:27 < englishman> but could be
2018-03-09T22:45:16 < Cracki> that heated printer bed is prolly gonna be PWMed
2018-03-09T22:45:27 < Cracki> but not at any frequency that's relevant for switching losses
2018-03-09T22:48:45 < Thorn> depends on how fast they're switching
2018-03-09T22:48:59 < Thorn> enough R and C and it's not really switching any more lol
2018-03-09T22:51:03 < Cracki> 4 gates 1 pin. atmegas might switch at most 16 million times a second.
2018-03-09T22:51:21 < Cracki> I'm confident this will heat the bed and not the fets
2018-03-09T22:52:33 < Rob235> should I go down to 3? 2 would probably even be okay wouldnt it?
2018-03-09T22:54:50 < Cracki> experiment
2018-03-09T22:55:01 < Cracki> try 1, see for how long you can touch it :>
2018-03-09T22:55:04 < Rob235> hmm I think I was wrong in how it works, so the normal 12v for the bed is what triggers the mosfet, I was thinking it was 5v from the mcu
2018-03-09T22:55:07 < Rob235> does that change anything?
2018-03-09T22:55:10 < Cracki> actaully, grab a meter, measure the resistance of the bed
2018-03-09T22:55:23 < Cracki> and tell us the resistance of that bed. that's fun to calc with
2018-03-09T22:55:36 < Cracki> 12 volts to the gate are ok too
2018-03-09T22:55:58 < Rob235> ok good
2018-03-09T22:56:00 < Cracki> these fets you posted earlier are logic level, so they respond to 3-4 volts already, but 12 will be peachy
2018-03-09T22:56:10 < Cracki> but don't feed the atmega 12 volts ok?
2018-03-09T22:57:03 < Cracki> oh right, if you drive the gates from the 12V *intended* for the bed, they'll charge in no time at all.
2018-03-09T22:57:24 < BrainDamage> you only have to switch the bed at a frequency faster than the time constants for to be effective
2018-03-09T22:57:29 < Cracki> no need for resistors. the gates are basically floating pieces of wire.
2018-03-09T22:57:32 < BrainDamage> and thermal constants are in the order of seconds
2018-03-09T22:57:37 < Cracki> ^
2018-03-09T22:58:00 < Rob235> looks like its lower than I expected, I'm reading 2.2 ohm
2018-03-09T22:58:17 < Cracki> 2.2 ohm for the bed? that means at most 5.5 amps
2018-03-09T22:58:27 < Rob235> yea, I was thinking more like 10a
2018-03-09T22:58:30 < Cracki> what were the fets named again?
2018-03-09T22:58:43 < Rob235> 30N06L
2018-03-09T22:58:44 < Cracki> maybe your meter has a bit of offset
2018-03-09T22:58:52 < Rob235> wouldnt be surprised
2018-03-09T22:58:55 < Rob235> its a cheap one
2018-03-09T22:58:57 < Cracki> use diff modet to cancel out
2018-03-09T22:59:00 < Cracki> if it has such a button
2018-03-09T22:59:07 < Cracki> what does it read if you hold the probes together?
2018-03-09T22:59:31 < Thorn> 73Ω
2018-03-09T22:59:35 < Cracki> uh nope
2018-03-09T22:59:42 < Rob235> 1,1
2018-03-09T22:59:44 < Rob235> 1.1
2018-03-09T22:59:45 < Cracki> ah good
2018-03-09T22:59:50 < Cracki> then the bed is prolly ~1.1 ohms
2018-03-09T22:59:59 < Cracki> that's ~11 amps
2018-03-09T23:00:25 < Rob235> I see
2018-03-09T23:00:42 < Cracki> at 12 volts for the gate, you get less than 30 mOhm
2018-03-09T23:00:59 < Cracki> so that might be 3.5 watts for a single fet
2018-03-09T23:02:16 < Rob235> think I could get by with two fets?

2018-03-09T23:02:48 < Cracki> possibly. I'll find the section on heat sinks
2018-03-09T23:03:08 < Rob235> I have these forged copper heatsinks that I bought for stepper motors but they are really for fets
2018-03-09T23:03:25 < Rob235> I have a few left over
2018-03-09T23:03:36 < Cracki> Thermal Resistance, Junction-to-Ambient -- 62.5 °C/W
2018-03-09T23:03:39 < Rob235> stepper drivers*
2018-03-09T23:03:43 < Cracki> so they won't even get that hot
2018-03-09T23:04:14 < Cracki> ya slap some on, can't hurt :P
2018-03-09T23:04:40 < Rob235> I wonder how much current the extruder takes, might as well add another one for that
2018-03-09T23:04:45 < Cracki> might even be touchably non-hot
2018-03-09T23:04:49 < Rob235> gotta be less than half the current of the bed
2018-03-09T23:05:06 < Cracki> heating x mm^3 of plastic per second
2018-03-09T23:05:37 < Rob235> I believe they are either .7A or 1.7A, not sure which steppers were which
2018-03-09T23:05:41 < Cracki> from ambient to ~200°C. consider specific heat of the plastic. consider losses to environment. you do the math :P
2018-03-09T23:06:01 < Cracki> 3d printer steppers tend to be ~1A, so both might be
2018-03-09T23:06:04 < Rob235> oh I'm thinking the stepper
2018-03-09T23:06:07 < Rob235> not the heater
2018-03-09T23:06:23 < Laurenceb> muh ublox is workinmg
2018-03-09T23:06:27 < Cracki> the motors themselves almost never need a heatsink. the stepper drivers perhaps
2018-03-09T23:07:21 < Cracki> they don't even need that much current. you only crank up the current so the driver can achieve the minimum current to cleanly display all microsteps.
2018-03-09T23:08:17 < Cracki> stepper drivers are notoriously bad at regulating almost-0 current. they can do 0, and a minimum. that's why you have "swallowed" step positions and might hear a beat.
2018-03-09T23:09:38 < Cracki> the problem is "fixed on-time" and and too high switching frequency of the driver. bigger motors (beefier coils take longer to charge up to target current), or less voltage, alleviate that.

2018-03-10T00:13:39 < qyx> also 3pin
2018-03-10T00:14:11 < upgrdman> what wire sizes does xt30 support? 12awg?
2018-03-10T00:14:26 < upgrdman> iirc 10awg gets noticably warm at 30A continuous
2018-03-10T00:15:21 < upgrdman> of course with RC, no one cares. keep it light and cheap.
2018-03-10T00:16:04 < qyx> https://www.tme.eu/sk/details/mt60-f/konektory-dc/amass/
2018-03-10T00:16:07 < qyx> this one looks cool
2018-03-10T00:17:44 < upgrdman> >12AWG
2018-03-10T00:17:49 < upgrdman> >60A
2018-03-10T00:17:51 < upgrdman> ya lol
2018-03-10T00:18:06 < karlp> didn't say for how long.
2018-03-10T00:18:17 < karlp> what's 12awg in mm2?
2018-03-10T00:18:34 < qyx> theres a table https://en.wikipedia.org/wiki/American_wire_gauge
2018-03-10T00:18:44 < qyx> about 3.3mm^2
2018-03-10T00:18:53 < qyx> so good to about 20-25A max
2018-03-10T00:19:13 < qyx> for 60A I would use 10mm^2 minimal
2018-03-10T00:19:50 < qyx> 63A AC in domestic installations mandates 16mm^2 here afaik
2018-03-10T00:20:55 < Cracki> ^
2018-03-10T00:21:11 < Cracki> that's why the output terminals are solid bars
2018-03-10T00:22:06 < Cracki> unless you want some heavy losses to heating wires, get a good crosssection
2018-03-10T00:27:09 < Rob235> ahh people answered and I left
2018-03-10T00:27:23 < Rob235> I guess that makes sense, didnt realize thats what the name was for
2018-03-10T00:28:10 < Rob235> alright so I'm gonna design a cover for the anet mainboard with a fan mount and a mount for my perfboard with mosfets
2018-03-10T00:28:25 < Rob235> xt30 will be fine for the mosfet connection

2018-03-10T10:50:29 < jadew> ok, I'll take it

2018-03-10T11:04:43 < Steffanx> I heard its boring now BrainDamage
2018-03-10T11:04:53 < jadew> saw it all
2018-03-10T11:05:13 < jadew> it's not the feel-good type of movie tho
2018-03-10T11:05:25 < jadew> it kinda ruins your mood
2018-03-10T11:06:18 < BrainDamage> unrelated: https://spectrum.ieee.org/tech-talk/aerospace/satellites/fcc-accuses-stealthy-startup-of-launching-rogue-satellites

2018-03-10T11:43:34 < kakimir> I plan to make hall current sensor out of iron wire
2018-03-10T11:43:41 < kakimir> and hall sensor
2018-03-10T11:44:06 < kakimir> where a loop of iron wire acts as core
2018-03-10T11:44:07 < BrainDamage> ...why iron
2018-03-10T11:44:23 < kakimir> because it's ferromagnetic
2018-03-10T11:44:31 < kakimir> ?
2018-03-10T11:44:41 < BrainDamage> oh as sensor?
2018-03-10T11:44:43 < kakimir> does my idea sound plausable?
2018-03-10T11:44:57 < BrainDamage> yes, careful only about saturation
2018-03-10T11:45:00 < kakimir> it's like the core that goes around the wire being monitored
2018-03-10T11:45:08 < kakimir> I don't care about saturation
2018-03-10T11:45:14 < BrainDamage> yes you do
2018-03-10T11:45:18 < BrainDamage> it fucks your measurement
2018-03-10T11:45:26 < BrainDamage> when it saturates it stops being linear
2018-03-10T11:45:35 < kakimir> I just need to know one thing only
2018-03-10T11:45:40 < kakimir> if there is current or not
2018-03-10T11:45:53 < kakimir> and I mean 100mA or even lower threshold
2018-03-10T11:46:25 < kakimir> I got easily to 150mA reliable threshold level with 3eur chinese split core hall sensor
2018-03-10T11:46:36 < kakimir> I plan to go lower and smaller
2018-03-10T11:46:44 < kakimir> in size smaller
2018-03-10T11:46:49 < BrainDamage> should work fine
2018-03-10T11:47:04 < kakimir> it needs to wrap around 2.5mm2 wire
2018-03-10T11:47:27 < kakimir> is it better to wrap it around it multiple times'+
2018-03-10T11:48:14 < kakimir> amperes can go as high as 20amps in the wire but only thing I need to know is threshold exceed or not
2018-03-10T11:48:44 < BrainDamage> make a C with the wire, and put the sensor inbetween the tips of the c
2018-03-10T11:48:55 < kakimir> yes
2018-03-10T11:48:56 < BrainDamage> single loop
2018-03-10T11:49:02 < BrainDamage> should suffice
2018-03-10T11:49:13 < kakimir> should I use normal steel cable from store?
2018-03-10T11:49:18 < kakimir> used to lift loads
2018-03-10T11:49:35 < BrainDamage> take a magnet and stick to it to test, not all steels are ferromagnetic
2018-03-10T11:49:44 < kakimir> or get iron or some iron alloy
2018-03-10T11:50:00 < BrainDamage> i question how reliable your setup is going to be tough if you buy random cables
2018-03-10T11:50:12 < BrainDamage> how many are you going to make?
2018-03-10T11:50:23 < kakimir> hundreds first
2018-03-10T11:50:26 < kakimir> then mass product
2018-03-10T11:50:42 < BrainDamage> changing brand of cable will mean changing mu, so calibration will differ
2018-03-10T11:51:39 < kakimir> mu?
2018-03-10T11:59:21 < BrainDamage> relative magnetic permeability
2018-03-10T12:00:27 < kakimir> I need to lock down some certain cable type
2018-03-10T12:00:52 < kakimir> is there iron cables with lackered strands?
2018-03-10T12:01:05 < kakimir> to reduce eddy currents
2018-03-10T12:03:24 < kakimir> does it matter if loop area is way bigger than the cable?
2018-03-10T12:03:44 < kakimir> to make installation in hard places easier?
2018-03-10T12:03:49 < kakimir> !
2018-03-10T12:05:33 < BrainDamage> just less sensitive, btw, it's important that you keep your loop rigid
2018-03-10T12:05:48 < BrainDamage> otherwise you fuck up the calibration coefficients again
2018-03-10T12:06:03 < BrainDamage> well, i guess it depends how much you care for it to be reliable
2018-03-10T12:13:13 < jadew> is there a channel for 3d printing?
2018-03-10T12:14:24 < BrainDamage> isn't that ##stm32?
2018-03-10T12:15:05 < jadew> ok then, any ideas on why I may get consistent layer shifting when printing a particular model?
2018-03-10T12:15:13 < jadew> I get the same amount of shift on the same layer

2018-03-10T14:37:39 < jadew> I guess I'll have to buy one that's currently supported

2018-03-10T14:58:48 < Steffanx> is it not even doing standard usb video class?
2018-03-10T15:03:17 < jadew> Steffanx, it is, but the driver won't work with it
2018-03-10T15:03:35 < tct> uvc
2018-03-10T15:03:39 < jadew> seems to work on another server tho, so I'm installing octoprint there
2018-03-10T15:05:39 < jadew> I'm hoping to figure out why I have the layer shift issue

2018-03-10T15:07:08 < tct> jadew, layer shift issues often come from current limitations on the drivers. But then again, that usually happens due to chinsy mechanics
2018-03-10T15:08:02 < jadew> tct, seems to always happen on that specific layer, on that model only
2018-03-10T15:08:08 < jadew> and by the same amount
2018-03-10T15:08:18 < jadew> http://5.12.8.164/stuff/20180310_121823.jpg
2018-03-10T15:08:30 < jadew> other objects are printing fine
2018-03-10T15:08:33 < tct> jadew, interesting
2018-03-10T15:08:38 < jadew> so I wonder if it's a slicing issue
2018-03-10T15:08:45 < jadew> maybe driving it too fast or something?
2018-03-10T15:08:54 < jadew> I hope the webcam will shed some light on it
2018-03-10T15:09:00 < dongs> the problem is you bought garbage
2018-03-10T15:09:13 < tct> jadew, I've seen this one. The issue was that the PSU got into current limiting mode in that special situation as there was too much/too fast movement
2018-03-10T15:09:22 < jadew> dongs, I like it so far
2018-03-10T15:09:25 < tct> but again, that's all on chinsy printers with low-quality <insert any noun>
2018-03-10T15:09:45 < Steffanx> and velleman.
2018-03-10T15:10:04 < jadew> this one seems to have a decent PSU, but who knows
2018-03-10T15:10:20 < Steffanx> You dont have a chinese printer anyway right?
2018-03-10T15:10:22 < jadew> I was actually admiring how fast it's printing
2018-03-10T15:10:41 < jadew> no
2018-03-10T15:10:56 < Steffanx> So stupid arguments are invalidated right away. :D
2018-03-10T15:11:20 < jadew> well... I see issues with it anyway, chinese or not
2018-03-10T15:11:30 < jadew> for example, I don't like that the Z-axis motors are at the bottom
2018-03-10T15:11:49 < jadew> when I oil those threaded rods, I have to make sure the oil doesn't get in
2018-03-10T15:12:10 < jadew> + it will collect dust right where it shouldn't
2018-03-10T15:12:36 < jadew> if they placed them at the top those two problems wouldn't exist
2018-03-10T15:13:17 < jadew> well, I guess that's it so far
2018-03-10T15:13:45 < jadew> I'm sure I'll find more things to complain about :)
2018-03-10T15:14:07 < jadew> but the motors at the bottom, facing up, seems like a really stupid decision

2018-03-10T15:14:57 < jadew> it's just that acrylic is more expensive than I thought
2018-03-10T15:15:01 < tct> what are you printering, Mr. jadew?
2018-03-10T15:15:14 < jadew> tct, a phone stand
2018-03-10T15:15:45 < tct> jadew, uhm... why?

2018-03-10T15:16:00 < jadew> so my kid can watch cartoons when we go out
2018-03-10T15:16:18 < tct> keep milking it, Rob235
2018-03-10T15:16:31 < tct> jadew, I see

2018-03-10T15:16:43 < Steffanx> No you dont
2018-03-10T15:16:48 < Steffanx> You want kids?
2018-03-10T15:16:52 < Rob235> I ordered filament yesterday, got some silver PLA and blue PETG on the way
2018-03-10T15:17:44 < jadew> this is the stand I'm making: https://www.thingiverse.com/thing:2490193
2018-03-10T15:18:58 < jadew> there are several nice versions, but that one seems both compact and properly adjustable
2018-03-10T15:19:22 < tct> that indeed is a nice stand

2018-03-10T15:21:10 < tct> jadew is an excellent parent. I learned that about a year ago (or so)
2018-03-10T15:21:16 < jadew> Steffanx, if he doesn't have something to do at the table, he leaves
2018-03-10T15:21:31 < Steffanx> How did people solve that issue in the past?
2018-03-10T15:21:41 < jadew> they didn't care
2018-03-10T15:21:44 < tct> wrong
2018-03-10T15:21:52 < Steffanx> Sure they did.
2018-03-10T15:22:00 < tct> they showed their kid who had the pants on

2018-03-10T16:42:21 < kakimir> now we are strugling with hall sensoring and costs
2018-03-10T16:43:02 < kakimir> bosses are saying it needs to be dirt cheap and prefferably a ready solution that is really small and sensitive
2018-03-10T16:43:20 < kakimir> I say it needs to work - it needs to work well
2018-03-10T16:44:49 < kakimir> it needs to just work and work in 99% cases out of the box without any problems
2018-03-10T16:45:02 < kakimir> competitor product works like 50% of time
2018-03-10T16:46:51 < kakimir> needs 400mA fast edge to sense anything.. mine works with 2-3eur chinese split core to 10mA without fast edges

2018-03-10T17:14:23 < Thorn> I fixed my stm8 rgb pulsing problem
2018-03-10T17:14:47 < Thorn> TIM2 prescaler 8 = TIM1 prescaler 255, not 256
2018-03-10T17:15:06 < Thorn> similarly, TIM2 prescaler 7 = TIM1 prescaler 127, etc.
2018-03-10T17:17:17 < Thorn> oh and I had to raise pwm frequency to over 900 Hz to make the pwm invisible
2018-03-10T17:17:46 < Thorn> (the mosfets are still cold with 5m of strip, thankfully)
2018-03-10T17:17:57 < Steffanx> Have a clue whats going on with those stm8s yet Thorn?
2018-03-10T17:18:11 < Thorn> nope no new info :(

2018-03-10T17:29:26 < Thorn> ATS665?
2018-03-10T17:34:01 < kakimir> most unlikelly
2018-03-10T17:34:13 < kakimir> it's linear sensing
2018-03-10T17:34:21 < kakimir> from hall split core current sensor
2018-03-10T17:35:46 < kakimir> does really good job
2018-03-10T17:35:55 < kakimir> in contrast what the whole thing costs
2018-03-10T17:36:16 < kakimir> whole current sensor is like.. few bucks
2018-03-10T17:44:13 < Cracki> 900 hz?
2018-03-10T17:44:23 < Cracki> you shouldn't see pwm beyond 70-100 hz
2018-03-10T17:44:37 < kakimir> true
2018-03-10T17:58:02 < Rob235> whats a better design for a single case fan? sucking in or blowing out
2018-03-10T17:59:52 < Rob235> Thorn: what are you doing with fpga? I have one that I never used
2018-03-10T18:00:42 < Thorn> Cracki: basically I can see light traces from the leds break up when I rotate my head (or even move my eyes), even @ 500 Hz
2018-03-10T18:04:48 < Thorn> Rob235: hopefully something useful lol (such as an sdr or some kind of analyzer)
2018-03-10T18:05:18 < Rob235> cool
2018-03-10T18:07:03 < Cracki> ah that
2018-03-10T18:07:21 < Cracki> motion blur is a consideration
2018-03-10T18:07:37 < Cracki> my led strips run at ~1 khz and that's where they stop the - - - -
2018-03-10T18:07:41 < Cracki> (about)
2018-03-10T18:09:21 < Thorn> and @ 250 Hz it somehow looks "sharp" even when I look at it directly
2018-03-10T18:13:55 < Cracki> btw, some presentation controllers with laser pointer modulate their laser like this

2018-03-10T22:23:28 < kakimir> do you have unsupported target ic?
2018-03-10T22:23:38 < kakimir> or poorly supported
2018-03-10T22:23:59 < kakimir> I think at least stm32s are well covered
2018-03-10T22:24:46 < kakimir> what ide you use catphish
2018-03-10T22:25:13 < kakimir> if it's eclipse based IDE then you need to google gnu arm eclipse
2018-03-10T22:25:39 < kakimir> you can do openocd debug sessions to your ide then
2018-03-10T22:26:30 < catphish> i'm using what i assume is a well supported device STM32L476RG Nucleo, however i don't have an IDE
2018-03-10T22:26:49 < kakimir> you are in team vim?
2018-03-10T22:27:14 < catphish> lol not quite, i have a nice text editor, but i am just using a simple script to compile and upload
2018-03-10T22:27:57 < catphish> i could probably move to a better IDE, especially if it'll help with debugging
2018-03-10T22:28:03 < kakimir> http://www.st.com/en/development-tools/sw4stm32.html
2018-03-10T22:28:06 < kakimir> it will
2018-03-10T22:28:21 < kakimir> that is eclipse based IDE for stm32 platforms
2018-03-10T22:28:52 < kakimir> mcuexpresso is similar tool for NXP LPC chips
2018-03-10T22:28:59 < kakimir> *mcuxpresso
2018-03-10T22:29:03 < catphish> i'll have a look, thanks
2018-03-10T22:29:57 < kakimir> with enought effort you may actually debug both platforms in both IDEs but there is some nice wizards usually per vendor
2018-03-10T22:31:55 < catphish> i'm not interested in NXP for now :)
2018-03-10T22:32:17 < catphish> but a nice way to debug stm32 would be lovely
2018-03-10T22:32:33 < catphish> struggling to find, and read peripheral registers in the openocd cli
2018-03-10T22:32:35 < kakimir> someone might have said that there is already gnu arm eclipse tools integrated in SW4
2018-03-10T22:32:53 < kakimir> but I have not confirmed that
2018-03-10T22:34:29 < kakimir> https://gnu-mcu-eclipse.github.io/plugins/download/ there is url to input into install packages or similar tool in ecplise tools menu iirc
2018-03-10T22:35:03 < kakimir> https://gnu-mcu-eclipse.github.io/plugins/install/ actually look at this rather
2018-03-10T22:35:40 < kakimir> in mcuxpresso that v4-neon url is not suitable and only old version mentioned below works
2018-03-10T22:35:55 < kakimir> may be same deal with SW4
2018-03-10T22:37:00 < kakimir> to see if you have openocd debuggin already intalled push debug button drop menu and see if there is configure debug sessions
2018-03-10T22:37:27 < kakimir> and then you can pick type of debug session to create and if you see openocd in the list it's already there
2018-03-10T22:39:38 < kakimir> and don't try to fiddle with workspace.. just create new source files and headers and copy paste your stuff there
2018-03-10T22:40:57 < kakimir> actually try to use it first with new hello world project and then try to debug it
2018-03-10T22:40:57 < catphish> just installing that system workbench, i'll see how it works
2018-03-10T22:41:30 < catphish> i'm happy to copy my code into a project

2018-03-10T22:43:25 < catphish> i'm getting on well with the stm32 anyway, only need 2 featured, pwm and adc, the first is working well :)
2018-03-10T22:44:07 < kakimir> in openocd debug session settings you can launch it locally directly from ide or you can set it running in CLI seperatelly and leave default port to listen and localhost as ip or you can actually debug remotelly via LAN - just
2018-03-10T22:44:29 < kakimir> write ip in the settings
2018-03-10T22:48:16 < karlp> catphish: are you sure you have all the clocks for l4 adc on
2018-03-10T22:48:31 < Steffanx> kakimir, you know TrueStudio is free nowadays right? Fuck this pluginnery and use truestudio instead.
2018-03-10T22:48:51 < catphish> karlp: all i did was to attempt to route the system clock to the ADC
2018-03-10T22:49:11 < kakimir> Steffanx, I have no idea what that is
2018-03-10T22:49:18 < kakimir> mcuxpresso does it's thing
2018-03-10T22:49:27 < kakimir> I don't need anything
2018-03-10T22:49:40 < kakimir> why should I bother?
2018-03-10T22:49:46 < Steffanx> TrueStudio = mcuxpresso for STM32 ( and a few other mcus)
2018-03-10T22:49:47 < catphish> karlp: just a single line: RCC->CCIPR |= (3<<28); i hoped this would provide the system clock to the ADC
2018-03-10T22:50:13 < kakimir> I bet it doesn't have as good wizards for lpc and stuff
2018-03-10T22:50:43 < Steffanx> It's even more "free" than mcuxpresso. The free mcuxpresso has a few limitation which you have to buy the pro version for to unlock them.
2018-03-10T22:51:15 < catphish> this IDE seems nice enough :)
2018-03-10T22:51:27 < catphish> just need to update my includes to match the new environment
2018-03-10T22:52:06 < Steffanx> Just give it a try once kakimir ;)
2018-03-10T22:52:55 < kakimir> I don't even know what limits there is
2018-03-10T22:53:14 < kakimir> I have not met the limits yet
2018-03-10T22:53:20 < Steffanx> one of them is limited SWV/SWO traces
2018-03-10T22:53:37 < kakimir> if I even had good SWO integration
2018-03-10T22:53:52 < kakimir> if I even had anything to probe SWO
2018-03-10T22:54:09 < Steffanx> any random lpclink can do it afaik.
2018-03-10T22:54:21 < Steffanx> At least those then come on those xpresso board can do it

2018-03-10T22:55:47 < Steffanx> That's not even mcuxpresso right? Looks like lpcxpresso :P
2018-03-10T22:55:54 < catphish> thanks, one thing at a time, just trying to get my code ported to the SW environment
2018-03-10T22:56:00 < PaulFertser> kakimir: seriously? If the number of break/watchpoints is not properly autodetected, it means target hardware is buggy.
2018-03-10T22:56:05 < PaulFertser> kakimir: are you sure that's needed?
2018-03-10T22:56:20 < kakimir> I atleast had issues without them
2018-03-10T22:56:32 < kakimir> I don't remember with lpc target it was
2018-03-10T22:56:34 < PaulFertser> I'd bet coincidence
2018-03-10T22:56:36 < catphish> the includes i was using are missing, i don't know where i find my constants
2018-03-10T22:56:55 < PaulFertser> Because you see the number of autodetected *points at connection time. I'm sure it matched.
2018-03-10T22:57:04 < catphish> previously i was using: #include <stm32l476xx.h>
2018-03-10T22:57:34 < kakimir> catphish, does SW4 wizard emerge CMSIS files?
2018-03-10T22:58:15 < kakimir> in mcuxpresso you create new mcuxpresso project and then you select CMSIS to use and it pops those files in your workspace
2018-03-10T22:59:36 < catphish> there's no option for CMSIS, https://i.imgur.com/XMomJmB.png
2018-03-10T22:59:52 < catphish> not in the wizard anyway
2018-03-10T23:00:13 < kakimir> try cube hal
2018-03-10T23:00:37 < kakimir> it may include CMSIS
2018-03-10T23:01:00 < kakimir> and HAL
2018-03-10T23:01:10 < kakimir> that you already used in your project
2018-03-10T23:01:33 < catphish> i don't use the HAL, but i guess importing it is harmless
2018-03-10T23:02:06 < kakimir> try
2018-03-10T23:02:45 < kakimir> usually those things create a lot of stuff you never use but just hang in your workspace
2018-03-10T23:05:15 < catphish> that's exactly what it appears to do, it created a full project with everything i need i think

2018-03-10T23:15:37 < catphish> kakimir: thanks, got it running and the debugger is excellent
2018-03-10T23:16:27 < kakimir> I assume you know your way around now?
2018-03-10T23:16:38 < kakimir> in terms of debugging tricks
2018-03-10T23:17:02 < catphish> i think so, breakpoints work, fetching peripheral registers works, thats all i need for now
2018-03-10T23:17:24 < kakimir> if you have tricky stuff with openocd PaulFertser is the Guru
2018-03-10T23:17:43 < catphish> my write to enable the ADC doesn't seem to have stuck, so that's the problem, just need to work out why not
2018-03-10T23:18:50 < kakimir> clocks not enabled, wrong bits toggled or wrong bits read
2018-03-10T23:18:53 < catphish> probably a clock problem
2018-03-10T23:19:04 < catphish> but i'm unclear what i've missed :(
2018-03-10T23:19:07 < kakimir> it's the classic
2018-03-10T23:19:44 < catphish> writing ADEN (ADC enable) from the debugger doesn't stick, so for whatever reason it's not powered up
2018-03-10T23:20:05 < kakimir> there might be powerdown registers in addition to clocks
2018-03-10T23:20:33 < kakimir> or is powerdown registers for sleep states - I don't know
2018-03-10T23:21:10 < catphish> i've done a couple of things to enable it and its clock, but i guess not enough
2018-03-10T23:22:15 < kakimir> you need to follow the clock diagram
2018-03-10T23:22:50 < kakimir> some chips have clock output for a gpio pin - you can switch clock at any point to the pin
2018-03-10T23:23:53 < kakimir> does ADC itself have clock divider and have you set it?
2018-03-10T23:24:38 < catphish> https://i.imgur.com/rffdgta.png all i've done is set the ADC clock mux to sysclk
2018-03-10T23:25:10 < catphish> i'll go check i did that correctly
2018-03-10T23:25:56 < kakimir> check if your code is effective
2018-03-10T23:26:24 < catphish> yep, checking that now
2018-03-10T23:26:42 < kakimir> there should not be anything clock related after it I'd say
2018-03-10T23:26:48 < kakimir> to overrun it
2018-03-10T23:28:46 < catphish> https://imgur.com/a/L82zd
2018-03-10T23:29:13 < catphish> the clock should be ok, i'll look again at the shutdown options (it has a deep sleep mode that's active by default)

2018-03-10T23:34:00 < kakimir> I'll check the reference manual
2018-03-10T23:35:43 < kakimir> page 506
2018-03-10T23:36:32 < kakimir> and page 507 figure 67
2018-03-10T23:36:40 < kakimir> have you done those prescalers?
2018-03-10T23:39:06 < catphish> i believe i'm using "option 1" with a system clock source
2018-03-10T23:39:39 < catphish> and no, i haven't set any prescalers
2018-03-10T23:43:20 < catphish> there's a few parts to it though, i'll go through the diagram on pg507 and see if i need any of those scalers
2018-03-10T23:44:03 < kakimir> can ADC handle 80mhz with prescaler /1 ?
2018-03-10T23:44:32 < catphish> i think it can, at least ST's gui seems to allow this configuration, but i can check

2018-03-10T23:45:03 < catphish> no, just the timers page
2018-03-10T23:47:47 < kakimir> see page 515 bottom too
2018-03-10T23:47:59 < kakimir> Software procedure to enable the ADC
2018-03-10T23:48:13 < kakimir> 1. Clear the ADRDY bit in the ADC_ISR register by writing ‘1’.
2018-03-10T23:48:23 < kakimir> 2. Set ADEN=1.
2018-03-10T23:48:44 < kakimir> etc. etc.
2018-03-10T23:48:55 < catphish> this is my init code: https://paste.ubuntu.com/p/Gs8xjkDwvM/
2018-03-10T23:49:41 < catphish> the problem is that all attempts to read/write ADC1->CR seem to fail
2018-03-10T23:51:26 < catphish> i'll try slowing down the ADC with a prescaler on the clock
2018-03-10T23:51:32 < kakimir> will it hang to while?
2018-03-10T23:52:30 < catphish> that while loop runs infinitely
2018-03-10T23:53:38 < catphish> i should look up what the maximum speed of the ADC actually is!
2018-03-10T23:54:01 < kakimir> datasheet have @ 80Mhz in some tables
2018-03-10T23:55:13 < kakimir> and 140khz minimum
2018-03-10T23:57:57 < catphish> i can't find that :(
2018-03-10T23:58:09 < kakimir> it should be fine
2018-03-10T23:58:43 < catphish> oh yeah, got it: Range 1 0.14 - 80 Range 2 0.14 - 26
2018-03-10T23:59:07 < catphish> i'm using range 1 i believe, with 80MHz sysclock so it should be ok
2018-03-10T23:59:15 < catphish> i feel like i'm missing something really obvious

2018-03-11T00:01:03 < kakimir> have you configured your system clock properly?
2018-03-11T00:01:41 < catphish> yes, the system clock is running at 80MHz, and it's routed to TIM1 which runs at 80MHz as expected
2018-03-11T00:05:24 < kakimir> AHB2 clock configured?
2018-03-11T00:06:50 < kakimir> do you have leds blinking or anything input output related working?
2018-03-11T00:07:00 < kakimir> AHB2 is connected to all that
2018-03-11T00:07:03 < kakimir> also ADC
2018-03-11T00:07:48 < kakimir> it's like memmory bus clock or something
2018-03-11T00:07:57 < kakimir> those can be disabled afaik
2018-03-11T00:08:00 < kakimir> and may be
2018-03-11T00:09:40 < catphish> i'm not entirely sure what AHB2 is, i have AHB routed to APB2 which drives my TIM1 and PWM, and that works correctly at 80MHz
2018-03-11T00:10:19 < kakimir> APB is peripheral clock
2018-03-11T00:11:00 < kakimir> AHB is data bus
2018-03-11T00:11:22 < kakimir> do you blink a led with your board or anything input output?
2018-03-11T00:11:23 < catphish> i think AHB2 drives my GPIO
2018-03-11T00:11:55 < catphish> good question, i'm using PWM, but i don't know if that actually uses AHB2, i can easily check
2018-03-11T00:12:43 < kakimir> if your chip has seperate IO config and seperate GPIO then no
2018-03-11T00:13:44 < kakimir> GPIO in that sense would not mean driver itself for the pins but a mode or a peripheral that those drivers are muxed to
2018-03-11T00:14:04 < kakimir> instead of your clock

2018-03-11T01:30:24 < karlp> _particularly_ on newer parts, it's always, "did you turn on all the clocks? did you _reallllly_ turn them on? no, I'm serious, check _every_ bit to see if you _realllly_ turned on what you needed"

2018-03-11T05:31:07 < upgrdman> guessing china has ic's
2018-03-11T05:31:26 < upgrdman> many small lipos have pcb with cut-off for under/over voltage and sometimes even overcurrent
2018-03-11T05:35:26 < dongs> thats single cell
2018-03-11T05:35:35 < upgrdman> no
2018-03-11T05:35:42 < upgrdman> i have a 2S LiPo with pcb in it
2018-03-11T05:36:02 < upgrdman> like 7.4V 800mAh or someshit
2018-03-11T05:37:10 < dongs> https://eewiki.net/display/Motley/Simple+Undervoltage+and+Overcurrent+Protection+for+Lithium-Ion+and+Lithium+Polymer+Batteries
2018-03-11T05:37:14 < dongs> well thats fucking great, for 2S
2018-03-11T05:37:44 < dongs> Luckily, TI offers the BQ296xxx line of overvoltage protection ICs for 2-4 cells.
2018-03-11T05:37:47 < dongs> neat
2018-03-11T05:37:57 < dongs> but it sounds like it still draws from the battery wehn its out
2018-03-11T05:38:57 < dongs> Low Power Consumption ICC ≈ 4	µA
2018-03-11T05:38:57 < dongs> (VCELL(ALL) <	VPROTECT)
2018-03-11T05:39:25 < dongs> hm why are these all OVERvoltage
2018-03-11T05:39:52 < dongs> These devices include a regulated 3.3V output supply that is disabled when any of the cells fall below the undervoltage threshold, thus avoiding over discharging the batteries. This output is intended for supplying power to low-power circuitry (less than 1mA) like an RTC [6], but it can also be utilized as an active-low undervoltage detection signal.
2018-03-11T05:39:57 < dongs> oh
2018-03-11T05:40:05 < dongs> ok that sounmds like a win
2018-03-11T05:43:32 < dongs> TI web datasheets are such fucking cancer
2018-03-11T05:43:36 < dongs> why are they even bothering
2018-03-11T05:45:43 < dongs> if I'm drawing very little current from a lipo, do I even need to use the fat wire feed? I can just tap bottom-most and top-post cell from balance connector right?
2018-03-11T06:12:46 < branjb> yeah
2018-03-11T06:13:18 < branjb> I do that with a taranis TX

2018-03-11T17:06:30 < branjb> anyone have any suggestions how I can make this table more rigid? I am assuming some crossbeams/triangles in certain places will help.  It's got a bit of a wobble and I need it to be solidly firm
2018-03-11T17:06:31 < branjb> https://imgur.com/a/8rMPn

2018-03-11T17:34:55 < Steffanx> oh hmm
2018-03-11T17:45:04 < aandrew> branjb: angle iron in the corners for bracing will help
2018-03-11T17:45:25 < aandrew> maybe also get some of those flat concrete patio stone "squares"  to put on the bottom shelf to help weigh it down too
2018-03-11T17:45:48 < aandrew> oh you already thought of my suggestion
2018-03-11T17:52:56 < branjb> what are angle iron?

2018-03-11T17:56:46 < aandrew> something like that, but I'd use triangles, they don't deform
2018-03-11T17:57:18 < aandrew> loosen off the screws holding the legs to the table, screw the metal brackets in tight then screw the table legs back in
2018-03-11T17:59:39 < aandrew> https://www.homedepot.com/p/Federal-Brace-Jefferson-12-in-x-12-in-Gray-Galvanized-Steel-Cabinet-Hanger-Left-40322/300244051 isn't exactly what I was thinking but that'd do
2018-03-11T17:59:42 < aandrew> seems awful pricey though
2018-03-11T17:59:52 < branjb> wew
2018-03-11T18:00:22 < branjb> I see, I bet I can find triangle pieces similar though that are cheaper
2018-03-11T18:00:26 < aandrew> exactly
2018-03-11T18:00:28 < aandrew> but that's the idea
2018-03-11T18:00:31 < branjb> yeah
2018-03-11T18:01:47 < branjb> was thinking about adding some miters on all of the lower beams connecting the legs, up to the top beams holding the table
2018-03-11T18:02:05 < branjb> dunno if it would help but I have plenty of spare 2x4
2018-03-11T18:02:54 < aandrew> where I used to work a long time ago they just would cut 12" corners off of plywood (so you have 12", 12" and whatever as the triangle out of plywood) and screw that on the sides
2018-03-11T18:03:44 < branjb> not a bad idea either
2018-03-11T18:03:56 < branjb> it'd be nice to find a steel bracket to do that
2018-03-11T18:05:56 < blacktronics> when you guys write functions, do you think about the order of arguments or do you just do it by feel and go with whatever makes most sense to you?
2018-03-11T18:06:23 < branjb> found https://www.homedepot.com/p/Simpson-Strong-Tie-16-Gauge-Concrete-Form-Angle-CF-R/100375334 but it looks like I designed my table poorly to use triangles.. no beams that it'll really go into well
2018-03-11T18:07:00 < branjb> blacktronics I always do objects/pointers first, parameters last but that's about the extent I think of it
2018-03-11T18:08:22 < aandrew> it looks like you could use those on the legs and screw them to the underside of the table surface, no?
2018-03-11T18:10:13 < branjb> i'm not sure how much that will do for rigidity, the table surface is just a bunch of planks of MDF
2018-03-11T18:11:16 < aandrew> you could take a bunch of 2x4s and screw them in the "inside" of that frame
2018-03-11T18:11:51 < aandrew> I'm building some workbenches when it gets warm out, my plan was to take 2x6s and stand them up "on edge" for the under-table surface
2018-03-11T18:12:10 < aandrew> then a sheet of OSB or MDF for the sub-surface, then steel plate for the surface
2018-03-11T18:12:59 < branjb> I kinda wish I took the extra effort to do welded steel
2018-03-11T18:13:06 < branjb> what do you mean on the "inside" of the frame?
2018-03-11T18:14:18 < aandrew> oh well if you look at the pic of your frame

2018-03-11T18:15:48 < aandrew> the left and right 2x4s on the skirt are longer than the front and back 2x4s
2018-03-11T18:16:01 < branjb> yeah
2018-03-11T18:16:03 < blacktronics> branjb: alright, seems like we're doing it right then, i am happy with a sample size of two
2018-03-11T18:16:14 < aandrew> I was suggesting cutting more 2x4s that would be in parallel with the left/right ones but shorter so they go inbetween the front/back ones
2018-03-11T18:16:40 < branjb> oh gotcha
2018-03-11T18:16:40 < aandrew> and put them on the inside of the frame, screwed to the front/back skirt 2x4s
2018-03-11T18:16:50 < blacktronics> just weld some quare steel together

2018-03-11T18:16:58 < branjb> haha
2018-03-11T18:17:01 < blacktronics> cheap and rigid
2018-03-11T18:17:04 < blacktronics> i weld everything
2018-03-11T18:17:04 < branjb> I was just thinking I wish I had done that
2018-03-11T18:17:10 < aandrew> my welding skills suck, it wouldn't be very square :-(
2018-03-11T18:17:22 < blacktronics> learn welding :P
2018-03-11T18:17:24 < branjb> mine too, how do you weld perfect flat/90 degree angles?
2018-03-11T18:17:25 < aandrew> although I should get some square tube steel and do that maybe
2018-03-11T18:17:29 < blacktronics> MIG is super easy to learn
2018-03-11T18:17:38 < aandrew> I have an old stick welder. mig's too fancy :-)
2018-03-11T18:17:54 < aandrew> branjb: welding magnets and clamps is how I'd think of doing it
2018-03-11T18:18:06 < blacktronics> ever since i picked up a mig welder i refuse to stick weld lol
2018-03-11T18:18:14 < blacktronics> really happy with flux cored mig welding
2018-03-11T18:20:03 < aandrew> yes I can definitely see how you'd prefer mig
2018-03-11T18:21:37 < blacktronics> i like how this more of a DIY channel with STM32 focus lol
2018-03-11T18:21:40 < blacktronics> i like this channel
2018-03-11T18:21:41 < aandrew> heh
2018-03-11T18:22:33 < aandrew> I'd expect that to weld a frame so it's flat and 90 degrees you need to clamp the pieces down so they're flat, and use something like a welding magnet (and more clamps) to make sure the corners are 90?
2018-03-11T18:22:57 < branjb> welded steel looks a lot nicer too

2018-03-11T18:27:22 < blacktronics> It's like a welding vice thing
2018-03-11T18:27:53 < fenugrec> just don't weld all one side before it's well tacked on both sides, otherwise you end up with  93deg bend (or 87...)
2018-03-11T18:28:19 < aandrew> heh yes
2018-03-11T18:28:49 < aandrew> verify angle, tack on inside, verify angle, tack on outside, verify angle, weld the shit solid

2018-03-11T18:29:36 < aandrew> then, because I'm a shitty welder, grind the shit pretty
2018-03-11T18:52:29 < kakimir> catphish, did you figure it out?
2018-03-11T18:53:06 < kakimir> what was the problem exactly?
2018-03-11T18:53:09 < catphish> kakimir: yep, did you miss my swearing rant at myself?
2018-03-11T18:53:23 < kakimir> yeah I see now
2018-03-11T18:53:48 < catphish> kakimir: it was really stupid, there's a timer required for the global ADC control
2018-03-11T18:54:00 < kakimir> interesting
2018-03-11T18:54:08 < catphish>   RCC->AHB2ENR |= RCC_AHB2ENR_ADCEN;
2018-03-11T18:54:19 < kakimir> that chip is really bloatty
2018-03-11T18:54:21 < catphish> i thought i'd searched for that, but clearly i missed it
2018-03-11T18:54:39 < catphish> is the f4 a fair bit simpler?
2018-03-11T18:54:41 < kakimir> what are you doing?
2018-03-11T18:55:13 < catphish> i'm making an induction motor controller, there's literally no reason to use the l series, it's just the board i happen to have to hand
2018-03-11T18:56:44 < c10ud^> catphish, are you using st igbts?
2018-03-11T18:56:49 < catphish> yes
2018-03-11T18:56:54 < kakimir> very interesting
2018-03-11T18:57:09 < kakimir> one of projects I'm looking for to do myself too
2018-03-11T18:57:30 < c10ud^> I was trying to make an induction heater and blew up a few so far, with l6384 driver :D
2018-03-11T18:57:36 < catphish> if anyone's interested: https://nutty.tk/inverter3.pdf
2018-03-11T18:57:51 < kakimir> catphish, generic AC motors or something more niche?
2018-03-11T18:58:08 < catphish> kakimir: generic 3 phase motors
2018-03-11T18:59:00 < c10ud^> is that kicad git?
2018-03-11T18:59:04 < c10ud^> is it stable so far?
2018-03-11T18:59:16 < catphish> i did this successfully last year using an atmega2560 and a rotary encoder on the motor shaft, this year's project is to try to do it without the rotary encoder and do feedback using current sensing
2018-03-11T18:59:33 < catphish> it's kicad nightly ppa, and it's been flawless
2018-03-11T19:01:27 < kakimir> c10ud^, kicad nightly is always buggy but stable
2018-03-11T19:01:31 < catphish> this is my "finished" project from last year https://www.youtube.com/watch?v=yQJ3dQz13DM
2018-03-11T19:01:45 < c10ud^> I was waiting for the stable version before making the switch but I am eager to try it
2018-03-11T19:02:07 < catphish> i switched to it because all the libraries in git require it, and it's been good so far
2018-03-11T19:03:09 < catphish> and this is my routing so far on this year's model: https://i.imgur.com/Dm0aedY.png
2018-03-11T19:03:20 < kakimir> I have used nightly pretty much always
2018-03-11T19:03:27 < kakimir> just don't update during project
2018-03-11T19:03:30 < catphish> on-board IGBTs this time, slightly smaller scale
2018-03-11T19:03:36 < aandrew> oh that's why it blew up. kicad
2018-03-11T19:04:31 < aandrew> what's your motor supply voltage?
2018-03-11T19:05:12 < catphish> "whetever"
2018-03-11T19:05:43 < aandrew> I'm just wondering why IGBTs if it's for little motors
2018-03-11T19:06:08 < catphish> the motor was using was 240VAC, so in theory, 340VDC, though i only ever tested it to 84VDC
2018-03-11T19:06:34 < catphish> that's as many volts as i was happy playing with
2018-03-11T19:06:50 < catphish> i'd have liked to have found a lower voltage AC motor, but they don't really exist :(
2018-03-11T19:09:57 < kakimir> are you looking to implement that VFD to some device?
2018-03-11T19:13:50 < catphish> not specifically, my ultimate goal is to build a DIY electric vehicle of some kind
2018-03-11T19:14:04 < catphish> but mostly just interested in learning how the motor control works
2018-03-11T19:16:45 < kakimir> 50hz/60hz induction motors are not very suitable
2018-03-11T19:17:40 < kakimir> because of high resistance or inductance.. or both and ofc really slow rotation speeds
2018-03-11T19:18:49 < kakimir> leading to really poor performance compared to weight
2018-03-11T19:19:24 < kakimir> I think tesla model S motor is driven up to 400hz
2018-03-11T19:20:27 < kakimir> it would instantly fry if connected to ~3phase mains
2018-03-11T19:20:53 < kakimir> without load voltage and current is kept low
2018-03-11T19:22:18 < Lux> depening on the power you want bldc motors are also an option
2018-03-11T19:22:25 < kakimir> yes
2018-03-11T19:22:27 < Lux> much easier to drive
2018-03-11T19:22:40 < Lux> and go up to 20kw or so easily available
2018-03-11T19:22:50 < Lux> probably even more
2018-03-11T19:22:57 < kakimir> electric airplane motors
2018-03-11T19:23:18 < kakimir> I think I found some that weight is only few kilos and output power is 30kw
2018-03-11T19:23:20 < Lux> i'd rather use ebike motors if it's something small
2018-03-11T19:24:06 < kakimir> I would like to find 500kw compact induction motor
2018-03-11T19:24:08 < catphish> kakimir: it's pretty complicated, but yes, higher frequencies and lower voltages would be nicer than the off the shelf motors, the torque achieveable with an industrial 3 phase motor is pretty impressive though
2018-03-11T19:24:13 < Lux> i bet in an application with low airflow those would just burn up on the spot at those loads
2018-03-11T19:24:44 < kakimir> there is temperature sensor Lux
2018-03-11T19:24:53 < kakimir> between coils somewhere
2018-03-11T19:25:10 < kakimir> you don't want your 3000eur bldc to fry
2018-03-11T19:25:15 < Lux> sure, but it's still an kinda ugly hack imo
2018-03-11T19:25:26 < Lux> using model motors for that kind of thing
2018-03-11T19:25:52 < catphish> i'm a big fan of industrial AC induction motors anyway, the only shame is that they require such high voltages
2018-03-11T19:26:05 < catphish> iirc the tesla runs at 700v or something similarly silly
2018-03-11T19:26:22 < Lux> how else would you push that kind of power ?
2018-03-11T19:26:44 < catphish> that's a good point :) smaller cars use a lot less, but don't produce the power
2018-03-11T19:26:48 < Lux> good luck pushing hundreds of kw at <60V
2018-03-11T19:26:52 < catphish> lol

2018-03-11T19:28:22 < kakimir> and really much €€$$
2018-03-11T19:28:36 < catphish> i guess that kind of thing is popular in bikes, i did consider them, but the power / $ ratio wasn't there when i looked
2018-03-11T19:28:53 < catphish> ac induction is cheap and reliable, but heavy
2018-03-11T19:28:57 < kakimir> http://emrax.com/products/emrax-188/ their smallest
2018-03-11T19:30:09 < kakimir> but this is not the motor I talked about.. we planned to make a trial bike with similar 30kw motor and high ratio gearing
2018-03-11T19:30:51 < kakimir> it was some switch company.. blue anodized rotor and big holes for airflow thru coils
2018-03-11T19:33:02 < kakimir> about 200mm diameter
2018-03-11T19:34:52 < aandrew> catphish: ah okay. I used to do industrial motor control (480 and 575V mostly) which is why I was asking
2018-03-11T19:35:14 < aandrew> 575VAC nominal has a DC link of approx 900V
2018-03-11T19:35:18 < catphish> is your real name andrew?
2018-03-11T19:35:28 < aandrew> why would I use an irc nick that is anything like my real name
2018-03-11T19:35:33 < catphish> :)
2018-03-11T19:37:18 < catphish> aandrew: the motors i look at are either 230v (325V DC bus) or 400v (565V DC)
2018-03-11T19:37:55 < catphish> but even 325v is pretty tricky to achieve with batteries, i'd quite like to build a large DC-DC converter to achieve this, but i dont know how yet
2018-03-11T19:38:47 < catphish> the toyota prius runs a 500V DC bus from a 200V battery so i know it's possible, but maybe not easy
2018-03-11T19:41:09 < aandrew> *nods* I spent a lot of time in that realm
2018-03-11T19:41:22 < aandrew> high voltage, high current DC busses still scare the shit out of me
2018-03-11T19:41:43 < Lux> balancing seems like a pita at those voltages
2018-03-11T19:41:45 < aandrew> want me to work on a 4kV soft starter? no problem.
2018-03-11T19:41:58 < aandrew> but a 480V inverter? I'm leery
2018-03-11T19:42:11 < aandrew> AC is so much more forgiving than DC
2018-03-11T19:42:49 < aandrew> our drives had really rock-solid IGBT drivers though. one time the hardware saved my life when the bus started oscillating with my head in the cabinet
2018-03-11T19:43:45 < catphish> aandrew: i've never put any serious power through anything i've build, the inverter i made last year could in theory handle 1000V 100A, but i would never play with that kinda power :(
2018-03-11T19:44:22 < aandrew> this is the kind of stuff that turns me on to electronics tbh
2018-03-11T19:44:49 < aandrew> you've got this tiny little micro shitting out 3V and it's controlling literal kW at high voltage/current right under it
2018-03-11T19:45:23 < aandrew> when I was in it it was hundreds of kW, it's a trip to design shit like that and it just works
2018-03-11T19:45:56 < aandrew> there's some times that it didn't though and you'd end up with a bellied-out steel enclosure or the thing jumping off the wall
2018-03-11T19:46:07 < catphish> lol
2018-03-11T19:46:07 < aandrew> somehow "oops" doesn't quite cut it there :-)
2018-03-11T19:46:20 < catphish> https://imgur.com/a/tjt4r
2018-03-11T19:46:34 < aandrew> nice bus
2018-03-11T19:46:52 < aandrew> whose cap is that? I don't think I've seen something like that before
2018-03-11T19:47:02 < catphish> i was pretty happy with the mechanical design on that in the end, i usually hate that kind of thing
2018-03-11T19:47:19 < aandrew> straight through design, nice simple lines, easy heatsinking. good job
2018-03-11T19:47:54 < catphish> http://uk.farnell.com/webapp/wcs/stores/servlet/ProductDisplay?catalogId=10001&langId=44&urlRequestType=Base&partNumber=2361718&storeId=10151
2018-03-11T19:48:10 < aandrew> we used some kind of plated copper bus bar
2018-03-11T19:48:18 < catphish> it's a serious capacitor :)
2018-03-11T19:48:24 < aandrew> it was silver coloured (but obv not silver), but if you cut it it was copper
2018-03-11T19:48:42 < aandrew> wow, nice
2018-03-11T19:48:55 < aandrew> when I was working in that field it was all still large "computer" electrolytics
2018-03-11T19:49:04 < aandrew> anywhere from a half dozen to two or three dozen
2018-03-11T19:49:22 < catphish> normal design is a large bank of electrolytics, and small film cap
2018-03-11T19:49:42 < catphish> but because i'm powering from battery, i really just needed the film cap, so i went big
2018-03-11T19:50:00 < aandrew> I like the bleed resistors too... lots of rookies forget that until they drop a screwdriver across it or reach in after it's been off for a weekend
2018-03-11T19:50:09 < catphish> lol indeed
2018-03-11T19:50:25 < aandrew> right, our stuff was all AC-DC-AC
2018-03-11T19:50:35 < catphish> the capacitor was delivered shorted out, i figured i should keep it that way :)
2018-03-11T19:50:38 < aandrew> so lots of ripple, SCR/diode front ends
2018-03-11T19:51:07 < aandrew> that really is a nice design though, well thought out
2018-03-11T19:51:58 < catphish> and a 3d printed shell, about 20 hour print :)
2018-03-11T19:52:14 < catphish> my printer wasn't big enough to make a full enclosure
2018-03-11T19:53:20 < catphish> my new design is totally different, all on a PCB, MUCH less power capability
2018-03-11T19:54:52 < catphish> the aim is to make a sensorless design this time
2018-03-11T19:54:53 < catphish> https://imgur.com/a/zGVwH
2018-03-11T19:55:31 < catphish> slot for STM32 at the end :)

2018-03-11T20:41:13 < catphish> in my setup here, should i be using AVDD from my nucleo board to power the hall effect ICs?
2018-03-11T20:41:41 < catphish> i had been assuming +3.3v was +3.3v, but it seems there's actually 2 separate 3.3V sources on the board
2018-03-11T20:43:10 < Cracki> avdd sounds like it's meant for analog stuff (low noise), so not intended for the sharply changing current pull of digital circuitry

2018-03-11T20:48:59 < catphish> i think it's an analog device, so i'll go with AVDD

2018-03-11T21:16:15 < Cracki> sheet says typical application wants the standard 100nf bypass caps, so shouldn't matter much
2018-03-11T21:17:13 < Cracki> nice specs on that ic
2018-03-11T21:21:42 < Cracki> their curves are a joke. they have 3 data points and fit a curve through that
2018-03-11T21:23:46 < karlp> allegro is like the ~only player in that market.
2018-03-11T21:23:52 < Cracki> perhaps
2018-03-11T21:24:40 < Cracki> I see infineon and mcp
2018-03-11T21:25:08 < Cracki> nvm, bad search results
2018-03-11T21:27:20 < Cracki> melexis offers something similar, superficially at least. I'm sure allegro knows what they're doing. it's just these ridiculous curves!
2018-03-11T21:30:24 < catphish> the allegro chips did seem the best of the poor selection on offer
2018-03-11T21:31:29 < sync> catphish: you can just buy a surplus toyota inverter
2018-03-11T21:31:41 < sync> but it is not incredibly fancy
2018-03-11T21:31:57 < catphish> sync: that could work :)
2018-03-11T21:32:50 < catphish> i tried putting a transformer on the AC output, works flawlessly, but i don't like it :)
2018-03-11T21:33:44 < sync> but why do you test your stuff with such a low dclink voltage?
2018-03-11T21:33:48 < sync> what is wrong with 320V?
2018-03-11T21:34:49 < catphish> it's just scarier
2018-03-11T21:35:33 < catphish> my electronics may be designed to take 600v, but actually plugging 300v DC into it is a little scary
2018-03-11T21:35:51 < sync> not really
2018-03-11T21:36:08 < catphish> the only way i can get that voltage is to build a mains rectifier
2018-03-11T21:36:50 < sync> yes
2018-03-11T21:36:53 < Cracki> put some fuses inbetween maybe

2018-03-11T22:04:36 < zyp> there might be a ferrite filter between vdd and avdd rails, but they should both come from the same place

2018-03-11T22:54:15 < catphish> ac induction controller
2018-03-11T22:54:38 < catphish> there's hall sensors, no voltage sensing
2018-03-11T22:55:36 < jpa-> i mean, no hall position sensors; i can see the hall current sensors
2018-03-11T22:55:52 < jpa-> but yeah, for induction motor i guess it can work that way
2018-03-11T22:56:28 < catphish> it's a "sensorless" controller, the idea is to measure current and compare it with the pwm voltage to calculate the back emd
2018-03-11T22:56:30 < catphish> *emf
2018-03-11T22:56:39 < catphish> i have no idea if it will work
2018-03-11T22:57:19 < jpa-> i think to calculate back emf, you need voltage sensing
2018-03-11T22:58:41 < jpa-> the typical idea is that you use either hall position sensors or voltage sensing to figure out the rotor position; then you decide the magnetic field orientation you want; then you control the PWM values so that the current becomes what you want - the current vector roughly equals the magnetic field direction
2018-03-11T22:59:39 < jpa-> but i've only dealt with BLDC's, induction motors are slightly different as the rotor has some "slip"
2018-03-11T23:00:00 < jpa-> so you can even drive it without any synchronization and it will spin, albeit with poor efficiency
2018-03-11T23:01:23 < fenugrec> Steffanx, you fixed it !
2018-03-11T23:01:27 < catphish> yes, an induction motor has slip, the frequency must be faster than the actual rotor speed
2018-03-11T23:02:12 < catphish> jpa-: one simple way to drive it is to measure the rotor speed with a sensor, and add a couple of Hz, that works pretty well, but required a mechanical sensor

2018-03-11T23:15:50 < catphish> the physical position of the rotor is entirely irrelevant as the magnet isn't attached to it, if you're clever enough, you can calculate the direction of the magnetic field of the rotor though, using current and voltage measurements
2018-03-11T23:16:18 < catphish> or in my case (i hope) current measurements, and voltage assumptions based on my PWM output
2018-03-11T23:16:21 < catphish> we'll see

2018-03-12T00:08:58 < Steffanx> Because theyre always from the uk :P
2018-03-12T00:09:13 < kakimir> and is there anyone else than Laurencer
2018-03-12T00:09:51 < Steffanx> Probably
2018-03-12T00:09:51 < catphish> my guess: english people don't care, because they're the majority
2018-03-12T00:10:05 < catphish> welsh / scotish people are more likely to identify as such

2018-03-12T00:52:03 < catphish> kakimir: well i made big tracks, i wasn't sure i had space for much more, anywhere in particular you think could be larger?
2018-03-12T00:52:19 < kakimir> catphish, you can make fills for any signal
2018-03-12T00:52:29 < blacktronics> Cats are nice
2018-03-12T00:52:31 < kakimir> then priorize them if needed
2018-03-12T00:52:45 < kakimir> and any copper layer
2018-03-12T00:52:56 < kakimir> then press B to fill and ctrl-b to unfill
2018-03-12T00:53:24 < catphish> you mean just make fills all over the place without thought and let the priorities turn them into tracks?
2018-03-12T00:53:40 < catphish> i've never tried that
2018-03-12T00:54:27 < kakimir> not all over the place
2018-03-12T00:54:27 < catphish> can i just make every net a huge fill and let kicad route everything?
2018-03-12T00:54:38 < kakimir> just around the traces
2018-03-12T00:54:44 < kakimir> side by side
2018-03-12T00:54:49 < kakimir> not overlapping
2018-03-12T00:54:51 < catphish> i guess i see what you're saying, there's a few places i could do it
2018-03-12T00:56:14 < kakimir> you don't need to remove trace or anything
2018-03-12T00:56:29 < kakimir> or fill around it but over it
2018-03-12T00:56:34 < catphish> does anyone know why when you make fills, kicad makes such tiny tracks into through-hole pins? rather than just connecting all the way round?
2018-03-12T00:56:43 < kakimir> trace will become one with fill
2018-03-12T00:56:59 < kakimir> heat relief
2018-03-12T00:57:04 < kakimir> for soldering
2018-03-12T00:57:10 < kakimir> check pad properties
2018-03-12T00:57:16 < kakimir> or footprint properties
2018-03-12T00:57:22 < kakimir> or fill properties
2018-03-12T00:57:33 < kakimir> depending what you want to change
2018-03-12T00:57:44 < kakimir> fill changes all defaults in the fill

2018-03-12T00:57:53 < kakimir> footpad is per footpad pins
2018-03-12T00:57:53 < catphish> ah makes sense
2018-03-12T00:57:59 < kakimir> pad is one pad only
2018-03-12T00:58:33 < kakimir> if you have overlapping fills you need to priorize them higher value is higher priority
2018-03-12T00:58:42 < kakimir> if you have a ground plane or so
2018-03-12T00:58:49 < kakimir> it's number 0 priority
2018-03-12T00:58:57 < kakimir> and signals are 1,2... etc
2018-03-12T00:59:26 < kakimir> all signals may be priority 1 or you can overlap signals if you use multiple priorities
2018-03-12T01:00:16 < kakimir> with fills you may want to set parameters for different signals
2018-03-12T01:00:16 < catphish> i should probably work out my required clearances, work out some priorities, then i can use a lot more fills
2018-03-12T01:00:22 < kakimir> like clearances
2018-03-12T01:00:59 < catphish> the biggest annoyance i have is connecting large tracks to small footprints
2018-03-12T01:01:19 < kakimir> limitations of kicad
2018-03-12T01:01:49 < catphish> i have SOC8s that take 20A, if i set up a design rule for the net, it makes it impossible to connect it
2018-03-12T01:02:04 < kakimir> just adjust your grid down and draw fill right around the pins
2018-03-12T01:02:17 < catphish> that may be the best solution rather than using tracks
2018-03-12T01:02:41 < kakimir> you need them tracks but just leave them under fills
2018-03-12T01:03:03 < kakimir> or actually you don't even need them.. there is no errors if you press B and fill it
2018-03-12T01:03:14 < catphish> should i just do everything with small tracks? then fill on top?
2018-03-12T01:03:40 < kakimir> connection to pins with traces affect thermal relief pattern
2018-03-12T01:03:58 < kakimir> unless you match to thermal relief copper pattern
2018-03-12T01:04:25 < catphish> seems like using small traces + fills will fix this
2018-03-12T01:04:29 < kakimir> you can "see thru" the trace in thermal relief
2018-03-12T01:06:16 < kakimir> with current layout not only traces will heat up but there is nothing but ambiet to conduct heat to from active power parts
2018-03-12T01:06:40 < catphish> that makes sense
2018-03-12T01:06:52 < kakimir> maybe not in few amps range but 20amps - certainly
2018-03-12T01:07:13 < catphish> i'll set up some design rules and start over with some small traces plus fills and see how it looks :)
2018-03-12T01:09:51 < kakimir> if your components pins match some grid it's easy to just pick 1/4 of that grid size and then draw fills around pins
2018-03-12T01:12:41 < kakimir> and have clearance like .254mm or .508mm right away

2018-03-12T01:18:44 < kakimir> opengl mode is a bit interesting to say
2018-03-12T01:19:11 < kakimir> it decides what to do with traces and everything in automatic placement mode
2018-03-12T01:19:48 < catphish> i was using opengl mode, its lovely, but it doesn't seem to work correctly
2018-03-12T01:19:58 < catphish> in legacy mode it's a lot more DIY but respects the rules
2018-03-12T01:20:36 < kakimir> it's just basically snap to grid and disallow anything that breaks design rules
2018-03-12T01:21:43 < kakimir> there is automatic placement button in top panel somewhere right from center
2018-03-12T01:21:56 < kakimir> it does different things in legacy mode and opengl mode
2018-03-12T01:22:23 < catphish> totally different, most notably it actually respects track clearance in legacy mode
2018-03-12T01:22:51 < kakimir> it's not uncommon to have a bug in such feature
2018-03-12T01:24:43 < kakimir> with kicad you need to look at bug tracer timelly manner if you feel uncertain
2018-03-12T01:25:47 < catphish> so i'm starting like this: https://i.imgur.com/Yg6rm4u.png
2018-03-12T01:26:06 < catphish> 0.5mm tracks for everything, clearances configured per net
2018-03-12T01:26:53 < catphish> thanks for all the help by the way :)
2018-03-12T01:30:09 < kakimir> fills respect rules only when there is different priority between them
2018-03-12T01:30:43 < kakimir> lower priority will give way
2018-03-12T01:30:48 < catphish> ok
2018-03-12T01:31:05 < kakimir> with same priority you need to draw the clearance
2018-03-12T01:31:31 < kakimir> in the fill shape or afterwars add keepouts
2018-03-12T01:32:51 < kakimir> not sure if keepout solution will produce error or not if fill lines overlap
2018-03-12T01:44:02 < kakimir> traces are higher priority than fills  so you dont need to avoid them

2018-03-12T11:19:41 < zyp> dongs, which way is it drifting? is it running too slow or too fast?
2018-03-12T11:22:16 < dongs> good question lets see i think +
2018-03-12T11:23:37 < dongs> hm still udner testing. not sure if it was just dumb user problem
2018-03-12T11:41:07 < zyp> also make sure it's actually running from LSE and not LSI
2018-03-12T11:41:38 < PaulFertser> LSI would be more like 38kHz so no wonder it'd be "drifting".
2018-03-12T11:43:55 < zyp> LSI is wildly inaccurate either way
2018-03-12T11:44:10 < dongs> i think this faggot is using cube
2018-03-12T11:44:16 < dongs> so shit should be running off LSE if specified
2018-03-12T11:44:16 < zyp> specced to something like 17-48 kHz
2018-03-12T11:44:22 < zyp> so it's useless for anything but IWDG

2018-03-12T12:34:41 < karlp> hrm, I've seen traces like that before, I just ignored it and assumed I was probing something wrong.
2018-03-12T12:34:48 < karlp> didn't seem to be having any affect.
2018-03-12T12:34:56 < karlp> uart rx or rs485?
2018-03-12T12:35:09 < karlp> what's with the reduced level?
2018-03-12T12:35:18 < dongs> y
2018-03-12T12:35:36 < dongs> thats what im wondering
2018-03-12T12:36:03 < karlp> like you got an unexpected voltage divider
2018-03-12T12:36:18 < dongs> well, it is 5V signal but its going into 5V-tolerant pin

2018-03-12T12:36:47 < dongs> my analol'g pal is saying that shit is because of clamping and looks different on the uart side inside the chip but im not buying it
2018-03-12T12:38:17 < dongs> hm wait, the crap is tehre while its not even receiving anything
2018-03-12T12:38:49 < dongs> thats noise while its trasmitting shit
2018-03-12T12:40:33 < zyp> that looks like obvious 5V and 3.3V steps
2018-03-12T12:41:05 < zyp> FT pins shouldn't clamp shit, that's the whole point of them
2018-03-12T12:44:14 < dongs> https://i.imgur.com/21DHotH.png ok that noise is during TX
2018-03-12T12:44:25 < dongs> ch1 = RX CH2 = TX
2018-03-12T12:44:31 < dongs> pink = REDE
2018-03-12T12:45:06 < zyp> ah, that makes sense
2018-03-12T12:45:15 < zyp> you've got pullup enabled on RX, I assume
2018-03-12T12:45:23 < dongs> the uart? yeah
2018-03-12T12:45:33 < zyp> it pulls to 3.3V when receiver is disabled, otherwise receiver outputs 5V while idle
2018-03-12T12:45:53 < zyp> so it switches between 3.3V and 5V when you're transmitting bytes
2018-03-12T12:47:03 < karlp> REDE is the rs485 transeiver, not tthe internal bit I presume
2018-03-12T12:47:07 < zyp> the solution would be to replace the internal 3.3V pullup with an external 5V pullup
2018-03-12T12:47:44 < karlp> oh, yeah, but that changes what the rs485 is putting out on it's line
2018-03-12T12:47:57 < zyp> but unless RX mistriggers on the changes between 3.3V and 5V, that shouldn't matter
2018-03-12T12:48:38 < karlp> hrm, i thought i'd seenthis sort of thing with my 3v3 transceivers too *shrugs* I never looked into it much, it wass't giving me any problems
2018-03-12T12:49:18 < zyp> karlp, I figure you'd see something similar with a 3.3V transceiver if you forgot pullup on RX
2018-03-12T12:49:32 < dongs> zyp, makes sense
2018-03-12T12:49:33 < dongs> testing now
2018-03-12T12:49:39 < zyp> then it'd go between 3.3V and floating
2018-03-12T12:50:33 < zyp> also, until now I hadn't even considered that the transceiver would tristate the RX pin when receiver is disabled
2018-03-12T12:51:15 < zyp> I don't think I've accounted for that at all in my RS485 thing
2018-03-12T12:51:16 < karlp> hrm, maybe, might hve been from old days, we have external pullup now for ages
2018-03-12T12:51:24 < karlp> nto sure when/why we added them
2018-03-12T12:51:33 < karlp> maybe we did look at this and I just forgot
2018-03-12T12:51:43 < dongs> https://i.imgur.com/5c4Lym2.png yep
2018-03-12T12:51:43 < karlp> I thought we added it for stable reset behaviour
2018-03-12T12:51:46 < dongs> when its floating its doing this
2018-03-12T12:53:57 < dongs> karlp: so the 485 doesn't always float the line high even when idle?
2018-03-12T12:54:12 < dongs> when RE/DE is in TX mode, the RX is floating on their side?
2018-03-12T12:54:27 < zyp> depends on the transceiver, I figure
2018-03-12T12:54:59 < zyp> RX/TX is the local interface, out of scope for the RS485 spec
2018-03-12T12:57:48 < karlp> yeah, RO is high-z when /RE is asserted.
2018-03-12T12:57:57 < karlp> on the isl83483 at least.
2018-03-12T12:58:11 < dongs> yeah these are some chinky max485 shts
2018-03-12T12:58:52 < karlp> so I _thought_ we had had an external pullup to avoid getting any spurious rx chars just after reset.
2018-03-12T12:59:03 < karlp> it's ages ago

2018-03-12T16:58:26 < perole> http://www.ti.com/lit/ds/symlink/lm2662.pdf
2018-03-12T16:58:37 < perole> a Switched Capacitor Voltage Converter :)
2018-03-12T16:58:47 < zyp> ah
2018-03-12T16:59:11 < perole> so intuitively the gnd pour around it will suck up all kinds of noise
2018-03-12T16:59:32 < perole> not much science behind it, hence the question :)
2018-03-12T16:59:56 < zyp> are you talking about ripple on the supply or what?
2018-03-12T17:00:22 < perole> if it can ripple up the supply, I presume it generates all kinds of other nastyness too
2018-03-12T17:01:38 < zyp> that ground pour doesn't do anything for supply ripples, if you want less supply ripples you need more decoupling
2018-03-12T17:02:35 < zyp> a small pour like that isn't useful for anything but thermal dissipation
2018-03-12T17:03:30 < zyp> and considering the chip doesn't have an exposed centerpad, I don't think it dissipates much anyway
2018-03-12T17:03:57 < perole> it let's out the magic smoke pretty quickly on overload :)
2018-03-12T17:04:53 < zyp> I wonder if that's the same part I designed in in a circuit that needed a negative supply
2018-03-12T17:05:48 < perole> not having a lot of supply experience, it was the path of least resistance
2018-03-12T17:06:43 < zyp> ah, no, TC7660S, but footprint looks more or less identical
2018-03-12T17:08:00 < perole> yup, even mentioned in the TI datasheet

2018-03-12T20:55:49 < jadew> I had to write some Java these days and I finally figured out why java programs are generally shit
2018-03-12T20:56:27 < jadew> because the language is shit, in a very particular way
2018-03-12T20:56:36 < jadew> it forces you to handle all exceptions...
2018-03-12T20:57:25 < jadew> good practice says you don't handle exceptions, unless you handle them properly
2018-03-12T20:58:58 < jadew> being forced to handle exceptions basically forces shitty developers to write shitty code, which they would otherwise fix and get working decently, because it would fucking crash, as it is supposed to
2018-03-12T21:00:08 < jadew> can't believe this is a constraint at the language level

2018-03-12T21:03:56 < Steffanx> I never did java, but how does it force you to handle exceptions?
2018-03-12T21:04:08 < jadew> it won't compile if you don't catch them
2018-03-12T21:04:18 < jadew> say you have function X which throws WhateverException
2018-03-12T21:04:26 < jadew> if you don't catch it, it doesn't compile
2018-03-12T21:04:55 < BrainDamage> you should be able to catch all in main, no?
2018-03-12T21:05:12 < jadew> I don't have a main here

2018-03-12T21:05:25 < jadew> I don't want to catch it
2018-03-12T21:05:28 < jadew> I want it to crash
2018-03-12T21:05:44 < Steffanx> no you dont
2018-03-12T21:06:21 < jadew> BrainDamage, I don't know where the entry point of this thing is, I don't think it has any
2018-03-12T21:06:27 < jadew> it has a bunch of activity classes
2018-03-12T21:06:36 < jadew> and they can be instantiated separately as far as I can tell
2018-03-12T21:07:38 < jadew> (by the OS)
2018-03-12T21:08:23 < jadew> Steffanx, you're joking or do you know something I don't?

2018-03-12T21:12:24 < Steffanx> Nah, im not entirely. You dont want your app to crash, not ever.
2018-03-12T21:14:53 < jadew> you want it to crash when it gets into a state you didn't predict
2018-03-12T21:15:42 < jadew> if you let it run like that, you can end up with corrupted data
2018-03-12T21:16:05 < Steffanx> but if your compiler can predict it then so should you right?
2018-03-12T21:16:22 < jadew> no
2018-03-12T21:16:39 < jadew> because the computer is not predicting it properly
2018-03-12T21:16:50 < jadew> for example, right now it was predicting a malformed url exception
2018-03-12T21:16:54 < jadew> for a hardcoded URL
2018-03-12T21:17:03 < jadew> I expect that to NEVER throw
2018-03-12T21:17:23 < jadew> and if it ever throws that exception, it should throw it, because it's not expected
2018-03-12T21:17:54 < jadew> there are behaviours which, even tho the underlying code can handle, are never expected or wanted in a particular application
2018-03-12T21:18:17 < jadew> if you design it in such a way that they shouldn't occur, then you also shouldn't handle the exceptions risen if they do
2018-03-12T21:18:33 < jadew> in those cases you want it to crash
2018-03-12T21:22:07 < jadew> I just realized something else

2018-03-12T21:29:32 < Steffanx> I still dont think it's a bad thing. And it's surely by design. As your method is probably defined with "throws bladieblaException". Cant you rethrow it btw?
2018-03-12T21:30:30 < jadew> Steffanx, it's useless code if I don't expect that thing to happen
2018-03-12T21:30:33 < jadew> and in this case, no
2018-03-12T21:30:38 < jadew> I actually have to handle it
2018-03-12T21:30:53 < jadew> because it just bubbles up and at some point you have to handle it
2018-03-12T21:31:30 < Steffanx> But <3 C# for not enforcing it.
2018-03-12T21:32:09 < Steffanx> But wont C# just popup some exception and continue to run (when it can recover)?
2018-03-12T21:32:35 < jadew> you can tell it to ignore it, but that's fine, at least it gives you the option to crash
2018-03-12T21:33:08 < jadew> you could argue that it's better than crashing, since the user might know better

2018-03-12T23:29:29 < Thorn> dunno lol
2018-03-12T23:31:19 < qyx> jadew: there are many guidelines and blogs talking about exceptions vs assertions vs return values
2018-03-12T23:31:31 < qyx> ssertions are here to handle your assumptions about what the code should do
2018-03-12T23:31:59 < qyx> exceptions are for handling invalid API usage, invalid user input, runtime errors (communication, out of memory, file not found, etc.)
2018-03-12T23:32:09 < qyx> ie. all errors which are somewhat common during runtime
2018-03-12T23:32:19 < qyx> return values are for actually returning the result
2018-03-12T23:32:40 < qyx> not like "read the temperature and if reading fails (device unconnected), return -100"
2018-03-12T23:32:59 < jadew> qyx, that's an expected case
2018-03-12T23:33:19 < jadew> you read the temperature, it fails, you handle that
2018-03-12T23:33:27 < jadew> but what you DON'T handle, should crash
2018-03-12T23:33:37 < jadew> and you shouldn't be forced to handle shit that SHOULD NEVER happen
2018-03-12T23:33:40 < qyx> its expected runtime error
2018-03-12T23:33:51 < jadew> that's the point, sometimes IT ISN'T
2018-03-12T23:33:55 < qyx> you MUST NOT handle it with special values
2018-03-12T23:33:59 < jadew> like in my example, with the hardcoded URL
2018-03-12T23:34:04 < jadew> that thing SHOULD NEVER fail
2018-03-12T23:34:14 < jadew> but if it does, I want the damn program to crash, because something is obviously wrong
2018-03-12T23:34:19 < qyx> sorry, I didn't catch the url example

2018-03-12T23:34:40 < jadew> my point is that some exception should be left unhandled
2018-03-12T23:34:53 < jadew> (most of them really)
2018-03-12T23:35:18 < qyx> if something is obviously wrong, throw an exception
2018-03-12T23:35:28 < qyx> I don't get that kind of reasoning
2018-03-12T23:36:00 < qyx> and handle it if it is your responsibility of course
2018-03-12T23:36:15 < jadew> qyx, did you read what my rant was about?

2018-03-12T23:36:27 < qyx> mmt
2018-03-12T23:36:31 < jadew> because I think we're mainly in agreement, except about handling them
2018-03-12T23:36:50 < jadew> my rant was about being forced to handle all the exceptions a piece of code might throw
2018-03-12T23:37:11 < jadew> my point is that, this sort of constraint forces bad code
2018-03-12T23:37:25 < jadew> because some exceptions should be left unhandled (like I said before, most really)
2018-03-12T23:37:49 < jadew> when shit hits the fan and you didn't plan for it, you don't handle that
2018-03-12T23:38:06 < jadew> because you don't even know what could be wrong, if you did, it would be part of the logic of the program
2018-03-12T23:38:24 < qyx> it is like not handling broken rope in an elevator

2018-03-12T23:38:54 < qyx> ok, there is a hardcoded url
2018-03-12T23:39:01 < jadew> the elevator crashes and you get yelled at
2018-03-12T23:39:03 < qyx> but still it is a parameter for a function
2018-03-12T23:39:08 < qyx> which defines some sort of api
2018-03-12T23:39:26 < jadew> I'm not going to check in my program for API changes
2018-03-12T23:39:28 < qyx> and if there is some DBC involved or whatever
2018-03-12T23:39:38 < qyx> it should crash in a predicted way, eg. by throwing some bad argument exception
2018-03-12T23:40:10 < jadew> that's exactly what I'm saying
2018-03-12T23:40:19 < qyx> but you should catch it
2018-03-12T23:40:22 < jadew> why?
2018-03-12T23:40:52 < jadew> how do I know what to do from there? considering it's something that I didn't foresee, so the reason why it's happening is unknown to me?
2018-03-12T23:41:12 < jadew> could be a number of things
2018-03-12T23:41:16 < jadew> corrupted data for example
2018-03-12T23:41:27 < qyx> it doesn't matter, fail softly
2018-03-12T23:41:27 < jadew> do I ignore the exception and continue with the save?
2018-03-12T23:41:39 < jadew> why?
2018-03-12T23:41:54 < jadew> so you get a bunch of bugs nobody will report?
2018-03-12T23:42:04 < qyx> because as Steffanx says, the program should never fail
2018-03-12T23:42:09 < qyx> or the user should not notice that
2018-03-12T23:42:15 < qyx> you can repeat the action
2018-03-12T23:42:17 < qyx> or whatever
2018-03-12T23:42:20 < jadew> that's exactly the other way around
2018-03-12T23:42:27 < jadew> you should always fail loudly
2018-03-12T23:42:37 < qyx> how
2018-03-12T23:42:46 < qyx> "application jadew's app stopped"

2018-03-12T23:43:04 < jadew> let it crash, if it's something you didn't plan for, the user will let you know
2018-03-12T23:43:05 < qyx> and samsung--; afterwards
2018-03-12T23:43:27 < jadew> if it's a bug that's just there and keeps going unreported it will simply lower your program's quality
2018-03-12T23:44:15 < karlp> jadew: you're not forced to handle exceptions where they're thrown though,
2018-03-12T23:44:16 < jadew> programs that recover from minor bugs, are programs that suck
2018-03-12T23:44:20 < karlp> that's where people get it wrong too much.
2018-03-12T23:44:21 < jadew> because they have lots of bugs
2018-03-12T23:44:44 < jadew> karlp, the problem with my scenario is that I only had the one class
2018-03-12T23:44:56 < jadew> I could either handle it in one function or the function calling that function
2018-03-12T23:45:03 < jadew> there was no entry point
2018-03-12T23:45:09 < jadew> (or I didn't find one)

2018-03-13T00:43:18 < kakimir> proper current paths
2018-03-13T00:44:53 < catphish> i finally learned how to configure the thermal relief properly, though in my case i opted for "solid connection" in all cases to maximize current and heat dissipation at runtime, hopefully it won't be a problem for hand soldering
2018-03-13T00:45:42 < kakimir> you can always use a blower an generous application of flux
2018-03-13T00:46:40 < dongs> nice kikecad there bro
2018-03-13T00:46:43 < kakimir> I'm building a BMS circuit prototype in work
2018-03-13T00:47:25 < kakimir> I find it easier to just and just connect stuff with soldering iron and then even it all out with reflow and flux
2018-03-13T00:48:00 < kakimir> making perfect finish to every solder joint and expose parts that are not soldered in
2018-03-13T00:48:23 < kakimir> those start to wave in airflow
2018-03-13T00:48:29 < kakimir> expose unsoldered pad
2018-03-13T00:52:13 < kakimir> I have complete copper fills and some joints are solid connection
2018-03-13T00:52:40 < kakimir> even ones with thermal relief just take forever to solder
2018-03-13T00:52:56 < catphish> well i'll see how i get on :)
2018-03-13T00:54:06 < kakimir> you can use whatever heating device to "preheat" the board
2018-03-13T00:54:18 < kakimir> to let's say to 100C
2018-03-13T00:55:12 < kakimir> with thermal relief I use trick to expand fill to as many side of the pin as possible
2018-03-13T00:55:37 < kakimir> so that there is more intact bridges
2018-03-13T00:58:53 < kakimir> I'd make bottom side upper fill higher
2018-03-13T01:00:07 < kakimir> current needs to go thru that what I assume to be around 2-3 millimeter width
2018-03-13T01:00:27 < kakimir> and I see only free space up there
2018-03-13T01:03:35 < catphish> you mean the trace top-right of my top image?
2018-03-13T01:04:07 < catphish> the bottom of the board is full afaik
2018-03-13T01:04:50 < catphish> "bottom side upper fill"?

2018-03-13T01:06:47 < catphish> oh i think i see what you mean

2018-03-13T01:07:19 < kakimir> I mean there is space for sufficient fill there
2018-03-13T01:07:25 < catphish> yep, that's what i eventually figured you meant :)
2018-03-13T01:07:30 < catphish> there is indeed room
2018-03-13T01:07:41 < catphish> and the first transistor makes a bottleneck
2018-03-13T01:07:46 < kakimir> yes
2018-03-13T01:07:51 < kakimir> and every second after that
2018-03-13T01:08:18 < kakimir> but first is the worst
2018-03-13T01:13:05 < catphish> https://i.imgur.com/Zxb2jAl.png
2018-03-13T01:13:17 < catphish> much better
2018-03-13T01:15:02 < catphish> there are of course still some hilareously small bottlenecks in the fom of the u4,u5,u6, wonder if they're actually designed to carry 20A, or just to measure it at peak
2018-03-13T01:15:08 < catphish> i suspect the latter
2018-03-13T01:16:54 < kakimir> it will heat up a bit
2018-03-13T01:16:58 < catphish> 1.2mOhm, pretty impressive
2018-03-13T01:17:16 < kakimir> but fight the easy battles
2018-03-13T01:17:46 < kakimir> I have a hint for a top layer comming up
2018-03-13T01:18:33 < catphish> 0.48W @ 20A, 23 degrees per watt
2018-03-13T01:18:51 < catphish> actually not as warm as i suspected (under ideal mounting conditions)
2018-03-13T01:19:08 < catphish> (with 800 mm2 of 4 oz. copper on each side)
2018-03-13T01:19:21 < catphish> i will not be using 4oz copper :)
2018-03-13T01:19:33 < kakimir> I should avoid it

2018-03-13T01:20:13 < kakimir> are those 8pin packs some sort of hall sensors?
2018-03-13T01:20:49 < catphish> yes
2018-03-13T01:21:02 < catphish> https://www.allegromicro.com/en/Products/Current-Sensor-ICs/Zero-To-Fifty-Amp-Integrated-Conductor-Sensor-ICs/ACS725.aspx
2018-03-13T01:24:21 < catphish> overall it should be very simple, STM32 drives 6 IGBTs via the high/low side drivers at the top, the current passes through the 3 hall effect sensors with analog output back into the STM32 ADCs
2018-03-13T01:25:20 < kakimir> https://drive.google.com/file/d/1t3RfYZJm7zKrmiDBsakDieE6N16j32Of/view?usp=sharing I don't know if it's discouraged to use copper fills under hall sensor but I would do this
2018-03-13T01:25:38 < kakimir> if you want to do that don't redraw fills
2018-03-13T01:25:39 < kakimir> just add
2018-03-13T01:26:09 < kakimir> some ICs need to have no copper fills under them
2018-03-13T01:26:43 < kakimir> I don't know what is the case with this ic
2018-03-13T01:28:12 < catphish> yes, i believe that's fine, i was only avoiding it for isolation, but i think there's still plenty of space there
2018-03-13T01:28:45 < catphish> i'll definitely add a couple of mm there about as much as you drew :)
2018-03-13T01:29:11 < kakimir> around pins current density is really high compared to other area

2018-03-13T01:39:49 < kakimir> it say you have cold joints even with thermal reliefs
2018-03-13T01:40:15 < kakimir> but maybe with a big lump of solder and powerful iron and flux
2018-03-13T01:40:17 < kakimir> eventually
2018-03-13T01:40:24 < kakimir> it will heat up
2018-03-13T01:40:38 < catphish> i have a decent iron at least :)
2018-03-13T01:40:51 < kakimir> there is improvised ways to heat up the board
2018-03-13T01:41:05 < catphish> i can always heat it in a normal home oven :)

2018-03-13T01:42:37 < kakimir> nice
2018-03-13T01:42:49 < kakimir> anyone else have opinion on this?
2018-03-13T01:45:02 < catphish> my power traces are now 9mm+ which is approx what is needed for 20A with 2oz copper
2018-03-13T01:45:10 < catphish> so that should be fine
2018-03-13T01:45:19 < catphish> i don't think anyone else cares :)
2018-03-13T01:45:34 < kakimir> I don't think 20amps is first thing you will do
2018-03-13T01:45:51 < kakimir> but it's good to do well at first time
2018-03-13T01:46:48 < kakimir> what does DRC say about your board?
2018-03-13T01:47:37 < kakimir> do you use saturn pcb toolkit for your power calculations?
2018-03-13T01:47:57 < kakimir> *trace power calculations
2018-03-13T01:48:14 < catphish> i was actually just using a random website http://circuitcalculator.com/wordpress/2006/01/31/pcb-trace-width-calculator/
2018-03-13T01:48:49 < catphish> it doesn't matter too much, the 20A is only a theoretical target, but it's nice to work to some spec
2018-03-13T01:49:04 < kakimir> well take a look at saturn pcb toolkit
2018-03-13T01:49:11 < kakimir> it will have all kind of stuff
2018-03-13T01:50:05 < kakimir> does basically thing on that page on one toolkit tab + all kinds of RF properties of traces
2018-03-13T01:50:13 < kakimir> and there is about 20 tabs more
2018-03-13T01:51:15 < kakimir> I wonder why programs keep uninstalling
2018-03-13T01:51:33 < kakimir> I swear I installed saturn and I have even empty directories there
2018-03-13T01:51:42 < kakimir> it must be win10 magic

2018-03-13T01:53:32 < catphish> DRC doesn't much like my design because i have overlapping zones
2018-03-13T01:54:15 < kakimir> priorize them
2018-03-13T01:54:26 < kakimir> most upmost highest number
2018-03-13T01:55:10 < kakimir> hmm
2018-03-13T01:55:19 < kakimir> maybe.. hmm
2018-03-13T01:55:41 < kakimir> you have stuff where clearances are not met - on purpose
2018-03-13T01:55:43 < kakimir> tricky
2018-03-13T01:55:59 < kakimir> like hall sense pins
2018-03-13T01:56:44 < kakimir> DRC won't stop you ploting gerbers
2018-03-13T01:57:02 < kakimir> ideally you bring the error count to 0 if it's possible
2018-03-13T01:57:45 < kakimir> else you just ignore whatever errors you think are unavoidable
2018-03-13T01:58:06 < catphish> ah, fixed it, just one badly drawn edge raised several design rule warnings
2018-03-13T01:58:22 < kakimir> usually
2018-03-13T01:58:52 < catphish> some of the clearances are nonsense because of the hall effect traces
2018-03-13T01:59:02 < catphish> but i'll try setting them in the design rules and see what happens
2018-03-13T02:03:25 < kakimir> now you have learned kicadding.. what do we in a month at this pace?
2018-03-13T02:03:34 < kakimir> *learn
2018-03-13T02:04:57 < catphish> get bored and do something else :)
2018-03-13T02:06:05 < kakimir> but seriously you have not learned kicadding before you do go arounds for bugs in your project files with a text editor
2018-03-13T02:06:44 < kakimir> basically edit by hand the point where wall came up

2018-03-13T15:50:54 < st32f072> Hi, I'm using an stm32f072 cortex-m0 chipset. Now I would like to implement a bottom half for an interrupt. I'm using a volatile uint8 var and set it to 1 inside the interrupt
2018-03-13T15:53:26 < st32f072> for some reason I can only clear that volatile variable in the main function and not in a function called from the main function
2018-03-13T15:53:48 < st32f072> does anyone know why it's like that?
2018-03-13T15:55:29 < qyx> I am not quite sure what a "bottom half for an interrupt" could be
2018-03-13T15:56:10 < st32f072> bottom half ... a routine which is not in the interrupt but transferring the dma data
2018-03-13T15:56:33 < st32f072> I'm only setting a flag in the interrupt and check that flag in a while() loop in the main function
2018-03-13T15:57:35 < st32f072> it seems to work properly that way, but if I try to touch that volatile variable inside a function which is called within the main loop the controller seems to stall

2018-03-13T15:57:55 < PaulFertser> st32f072: you should be able to change global variables from any function. Is your "bottom half" function physically in the same file (hence, compilation unit) as main?
2018-03-13T15:58:08 < qyx> I am still lost
2018-03-13T15:58:23 < PaulFertser> (some people get duplicated global symbols due to improper extern/include usage)
2018-03-13T15:58:28 < st32f072> PaulFertser: yes it is
2018-03-13T15:59:20 < PaulFertser> st32f072: if in doubt, you can check the assembly listing, instructions to set/clear a global volatile uint8_t should be pretty obvious. I'd bet your problem is something else.
2018-03-13T16:02:56 < kaa> where to ask avr questions?
2018-03-13T16:03:14 < PaulFertser> kaa: in time machine 10 years ago
2018-03-13T16:03:36 < kaa> did I make mistake
2018-03-13T16:03:48 < kaa> by using attiny20 in my design?
2018-03-13T16:04:02 < jpa-> ##microcontrollers still accepts 8051 questions also
2018-03-13T16:04:03 < kaa> I should pick components that chinese have already copied
2018-03-13T16:04:22 < PaulFertser> kaa: well, seriously, any reason to use AVR these days? You get stm32 dirt cheap, and stm8 even cheaper. With proper peripherals, available debugging and all the other goodies.
2018-03-13T16:04:39 < kaa> but I only need to lit some leds
2018-03-13T16:05:38 < kaa> 8051 is still relevant
2018-03-13T16:05:40 < PaulFertser> kaa: how much will attiny20 cost you?
2018-03-13T16:05:44 < kaa> or is it 8052

2018-03-13T16:06:16 < kaa> exact chip
2018-03-13T16:06:29 < kaa> we make at least 100 first
2018-03-13T16:06:35 < kaa> maybe thousand after that
2018-03-13T16:06:37 < kaa> and so on
2018-03-13T16:07:19 < kaa> 0.4eur exl.vat in 100pcs
2018-03-13T16:07:21 < jpa-> besides, who cares, if it does the job
2018-03-13T16:07:33 < kaa> I care if they suddenly drop it
2018-03-13T16:07:56 < jpa-> yeah, but that's a risk that you'll have with any microcontroller
2018-03-13T16:08:03 < kaa> yes
2018-03-13T16:08:11 < jpa-> the more common the better :P
2018-03-13T16:08:56 < qyx> I recommend at89c2051
2018-03-13T16:09:31 < PaulFertser> kaa: so http://www.fischl.de/usbasp/ says it has TPI support in the latest version
2018-03-13T16:09:49 < st32f072> Weird, since the volatile variable is cleared in the main function there's no problem. I'll have a look at it later again I'll just continue with my project first
2018-03-13T16:10:10 < kaa> PaulFertser, it's what I assumed
2018-03-13T16:10:21 < kaa> by what I read from internets
2018-03-13T16:10:29 < kaa> friend is coming to bring another usbasp
2018-03-13T16:10:38 < qyx> st32f072: a minimal code example would help
2018-03-13T16:10:44 < jpa-> pic16f84 has been available since 1993 and probably longer than any of the current STM32's :P
2018-03-13T16:10:49 < PaulFertser> kaa: usbasp from china comes with old firmware, but you should be able to easily reflash it.
2018-03-13T16:10:51 < kaa> so I those programmers can fuck each other

2018-03-13T23:09:13 < blacktronics> using this http://www.martinhubacek.cz/arm/improved-stm32-ws2812b-library
2018-03-13T23:09:28 < blacktronics> it's definitely doing something since leds are turning white but that's about it lmao
2018-03-13T23:09:57 < inca> blacktronics: try manually doing it? blocking mode?
2018-03-13T23:10:06 < inca> probe serial line.
2018-03-13T23:12:01 < blacktronics> i wish i had a scope or logic analyzer to poke the output
2018-03-13T23:12:37 < blacktronics> i have no clue what is going on though
2018-03-13T23:12:44 < inca> All on or all off doesn't mean much.
2018-03-13T23:13:04 < inca> Do a blocking serial output string and blink some LEDs on the strip.
2018-03-13T23:13:41 < blacktronics> idk what that means
2018-03-13T23:13:49 < blacktronics> it does seem to send a bunch of garbage and then a reset pulse though
2018-03-13T23:14:21 < inca> The DMA driver just takes the memory and writes a serial string from it... to the LED strip.
2018-03-13T23:14:39 < inca> So test the comms part.
2018-03-13T23:14:45 < blacktronics> ye i still don't fully understand how that all plays together and is set up
2018-03-13T23:14:53 < inca> You don't need to.

2018-03-13T23:24:27 < blacktronics> inca: thx, i do want to understand how this works though haha
2018-03-13T23:24:56 < Steffanx> zyp, your version is not casting 0 to a function pointer with  no argument and no return value and then calls it right?
2018-03-13T23:26:37 < zyp> it isn't?
2018-03-13T23:28:43 < zyp> I'm wrong though, jpa-'s syntax is right
2018-03-13T23:28:49 < zyp> so disregard :)

2018-03-14T01:28:56 < karlp> no, I'ðm kinda interested in the idea of it, but never tried it myself.
2018-03-14T01:29:17 < karlp> had a hard enough time trying to run rust on a router platform, not really sure i'm convinced yet of rust on stm32 :)
2018-03-14T01:29:43 < karlp> though, I last tried that 3-4 years ago, I'm sure it's "better" now
2018-03-14T01:29:48 < branjb> i guess i had been living in a box, hadn't even heard of rust till laslt month
2018-03-14T01:30:15 < branjb> coworker was telling me about it and it seems p decent for real time embedded... if it actually works
2018-03-14T01:31:28 < karlp> "realtime"  is irrelevant

2018-03-14T01:45:52 < jadew> the previous one I tried to print had a bunch of shortcomings
2018-03-14T01:46:26 < jadew> for one, it was too stiff so if you hit the probes by mistake you'd run the risk of breaking them, instead of having them fall off

2018-03-14T13:04:18 < stm32f072> Hi, I have just completed my small project which is passing data via USB to a PC. I stumbled over overloading the STM32 by triggering too many interrupt requests via USB. Is there any way to verify/avoid such an issue in advance?
2018-03-14T13:05:14 < karlp> don't do that?
2018-03-14T13:06:14 < stm32f072> of course I don't want to do that but how can I verify that the performance of the stm32 part is sufficient?
2018-03-14T13:06:17 < stm32f072> just try and error?

2018-03-14T13:07:23 < stm32f072> STM32F4 has no such problem of course but I wanted to go for a smaller part and learn about it
2018-03-14T13:22:52 < Thorn> how do you overload a stm32 with usb interrupts? roughly speaking, no new usb interrupts will be generated until you service an outstanding one
2018-03-14T13:23:17 < Thorn> at least for the same endpoint
2018-03-14T13:23:45 < Thorn> do you have a target throughput you need to achieve?
2018-03-14T13:24:45 < Thorn> (and there will be no overruns unlike e. g. uart, unless the EP is isochronous)

2018-03-14T13:45:06 < Cracki> "overloading" would mean the data is coming in such short periods that the interrupt handler hasn't finished processing. thus, interrupt requests can't be processed fast enough.
2018-03-14T13:45:36 < Cracki> define "stumbled over"
2018-03-14T13:46:00 < Cracki> the claim needs an explanation from your source, not guessing from anyone else
2018-03-14T13:51:05 < Thorn> why can't I see messages from crt. I don't have him on /ignore

2018-03-14T14:51:25 < stm32f072> as long as I throttle the usb interrupts a bit it's no problem
2018-03-14T14:51:46 < Laurenceb> I liek this new jtag interface

2018-03-14T16:18:26 < blacktronics> what does it shake
2018-03-14T16:18:31 < blacktronics> i dont know nothing about your project

2018-03-14T16:18:36 < Laurenceb> I dont either
2018-03-14T16:18:40 < blacktronics> good
2018-03-14T16:18:43 < blacktronics> that was actually funny
2018-03-14T16:18:45 < Laurenceb> I supposed to be doing something...
2018-03-14T16:18:54 < BrainDamage> what are you using to generate those plots?
2018-03-14T16:19:26 < Laurenceb> GNU-Octave
2018-03-14T16:19:29 < BrainDamage> thanks, I'll make sure to avoid it in the future, they look like shit

2018-03-14T16:20:07 < Laurenceb> I thought they looked quite good lol
2018-03-14T16:20:58 < BrainDamage> seriously? with lines exceeding the axis grids? or that it's not clear where the sampling points are
2018-03-14T16:21:17 < BrainDamage> also the lines are heavily aliased
2018-03-14T16:21:25 < Laurenceb> lel thats my config
2018-03-14T16:21:26 < blacktronics> does not really matter for what he is trying to finger out does it?
2018-03-14T16:21:35 < blacktronics> like
2018-03-14T16:21:41 < Laurenceb> I used the "tight" stuff
2018-03-14T16:21:54 < blacktronics> to me it seems this is merely to figure out if its doing weird shit
2018-03-14T16:22:38 < Laurenceb> yeah
2018-03-14T16:22:45 < blacktronics> BrainDamage: i have made worse graphs before
2018-03-14T16:22:48 < Laurenceb> thats running with two iepe sensors
2018-03-14T16:23:02 < Laurenceb> I'm going to run it with iepe versus mems sensor
2018-03-14T16:23:08 < Laurenceb> to calibrate the mems stuff
2018-03-14T16:23:14 < karlp> blacktronics: that's not a claim to fame
2018-03-14T16:23:24 < blacktronics> it's not supposed to be
2018-03-14T16:23:26 < Laurenceb> one sensor is reference, the other is device being tested
2018-03-14T16:23:27 < BrainDamage> a plot system is generic, it's useful both when you're interested in qualitative and quantitative data, in this case he only cares for qualitative, were he wanting quantitative, he'd have to spend quite a bit time to sanitize that
2018-03-14T16:24:08 < BrainDamage> personally, i don't want to fap to make my tools to work more than necessary
2018-03-14T16:25:25 < BrainDamage> i am not speaking of publication ready, i just want the plot values to be legible for myself
2018-03-14T16:25:55 < blacktronics> ^
2018-03-14T16:26:37 < blacktronics> i once made a thing to display a bunch of graphs on top of eachother , the graphs were simply roughly scaled, it would sometimes exceed into the interface bit and keep a bunch of pixels stuck on because they weren't being refreshed
2018-03-14T16:26:41 < blacktronics> it was a true beauty
2018-03-14T16:27:18 < karlp> sure soundsd like it :)
2018-03-14T16:29:39 < zyp> bokeh does pretty good-looking graphs

2018-03-14T19:19:13 < Laurenceb> inb4 magic smoke
2018-03-14T19:22:46 < ggVGc> are there any ready arm dev boards with multiple ADCs and DACs that you guys would recommend_
2018-03-14T19:22:47 < Laurenceb> yay it works
2018-03-14T19:22:56 < ggVGc> or some other idea? I want to make a prototype for a digital synth module
2018-03-14T19:23:17 < Laurenceb> almost proper signal levels too, maybe 3dB mismatch between adc saturation and saturation leds on the preamp
2018-03-14T19:23:30 < ggVGc> I'd rather spend less time, initially, on building the analog parts of the circuit
2018-03-14T19:25:20 < karlp> two dacs and up to three adcs on most stm32 dev boards.
2018-03-14T19:25:44 < ggVGc> ah, nice
2018-03-14T19:25:52 < ggVGc> I'd prefer a bit more, but that's a good start
2018-03-14T19:26:35 < emeryth> why do you need more than one DAC?
2018-03-14T19:26:57 < ggVGc> emeryth: what I want to make is a multi-channel mono sampler, basically
2018-03-14T19:27:11 < ggVGc> to use with my modular synths
2018-03-14T19:27:39 < ggVGc> so I need one pair of ADC/DAC per channel
2018-03-14T19:31:22 < qyx> stm32 dac is probably not super hifi quality
2018-03-14T19:32:24 < ggVGc> not sure it matters for my initial prototyping
2018-03-14T19:32:37 < Laurenceb> unlike muh audiophool kit
2018-03-14T19:32:38 < ggVGc> what's problematic though, I realised, is I need 10v output
2018-03-14T19:32:39 < Laurenceb> amirite
2018-03-14T19:32:51 < ggVGc> so I need to build the analog part anyway probably..

2018-03-14T21:54:27 < blacktronics> i am about to ram this discovery board into my jugular
2018-03-14T21:55:02 < jpa-> considering that each instruction takes 5-10 nanoseconds depending on your cpu freq, asm("nop"); is probably your friend
2018-03-14T21:55:33 < blacktronics> yeah it doesn't seem to work for shit for me, i must be doing something wrong
2018-03-14T21:55:47 < jpa-> how do you test it?
2018-03-14T21:56:01 < jpa-> remember that e.g. gpio write can take a lot longer than 1 instruction
2018-03-14T21:56:29 < blacktronics> yeah i figured as much, i ordered one of them cheapo logic analyzers but it won't be here for a while
2018-03-14T21:56:38 < blacktronics> i am trying to just bitbang drive some ws2812
2018-03-14T21:56:55 < jpa-> eh
2018-03-14T21:58:08 < jpa-> not like you'll see "couple of nanoseconds" very well with a max 24 MHz analyzer
2018-03-14T21:58:28 < jpa-> and besides, there are peripherals for this
2018-03-14T21:58:34 < blacktronics> https://pastebin.com/bLwe9Adp
2018-03-14T21:58:40 < blacktronics> i know there are peripherals for this
2018-03-14T21:58:44 < blacktronics> and i have no idea how to use them
2018-03-14T21:58:46 < blacktronics> start small right?
2018-03-14T21:59:04 < jpa-> yeah
2018-03-14T21:59:22 < jpa-> why do you think the delay doesn't work?
2018-03-14T21:59:28 < blacktronics> the board is a F746 discovery
2018-03-14T21:59:36 < blacktronics> set at 216Mhz
2018-03-14T21:59:42 < blacktronics> it kinda works but doesn't
2018-03-14T21:59:51 < blacktronics> the led goes full white
2018-03-14T22:00:51 < blacktronics> if i make a copy of all those for loops the second led also lights but also full white
2018-03-14T22:00:55 < Rob235> try a lower T0H?
2018-03-14T22:01:39 < jpa-> hal_gpio_writepin is probably pretty slow also
2018-03-14T22:02:11 < jpa-> i'd use a timer to get the delays accurate, even if not bothering with anything more advanced
2018-03-14T22:02:20 < Rob235> yea, I used timers for my ws2812 driver
2018-03-14T22:02:23 < jpa-> with flash prefetch etc, you can't really rely on instruction timings

2018-03-14T22:47:34 < blacktronics> Laurenceb: have you ever considered opening hackertyper on one screen so the russian grll thinks you are doing a lot of work?
2018-03-14T22:47:57 < kakimir> Steffanx, about to install some plugins to my browser
2018-03-14T22:48:11 < Steffanx> blacktronics you know that doesnt actually gets him do his work faster right?
2018-03-14T22:48:57 < Steffanx> and typing like a madman requires even less attention that what he should be doing. > more trolling time
2018-03-14T22:49:07 < blacktronics> yeah but it will /look/ like he is working very hard

2018-03-14T23:02:06 < Steffanx> *won
2018-03-14T23:02:21 < kakimir> generally people are quite happy
2018-03-14T23:02:28 < kakimir> which is suprising
2018-03-14T23:07:26 < karlp> BrainDamage: the wifi+ble chip now has a specially markd raspberry can on it though!
2018-03-14T23:09:05 < karlp> I like it supprots "giga"bit ethernet now too!
2018-03-14T23:14:05 < Steffanx> 300mbit is still more than the old 100mbit
2018-03-14T23:14:21 < karlp> sure, you can use even _more_ of your usb bandwidth :)
2018-03-14T23:14:22 < kakimir> I have 10Mb
2018-03-14T23:14:32 < kakimir> actual 11
2018-03-14T23:16:45 < kakimir> you need a satellite connection out there to get 1Mb

2018-03-14T23:51:23 < kakimir> model for adults
2018-03-14T23:51:44 < kakimir> really nice but can't keep it without swinging around while riding
2018-03-14T23:53:53 < kakimir> besides I need constantly fear for falling on top of it

2018-03-15T02:49:41 < branjb> is this a sign of autism http://i.4cdn.org/pol/1521071159660.jpg
2018-03-15T02:51:57 < con3> I feel like thats more than a sign
2018-03-15T02:52:05 < jadew> I have a similar picture since when I used to live alone
2018-03-15T02:52:12 < branjb> those disgusting bedroom pics always fascinate me
2018-03-15T02:52:20 < branjb> how does that start/happen/progress?
2018-03-15T02:52:41 < jadew> by not giving a shit
2018-03-15T02:53:06 < jadew> if it doesn't bother you, then you don't have to clean it up
2018-03-15T02:53:12 < jadew> and it piles up fast
2018-03-15T02:53:42 < jadew> I remember one time I had a stack of pizza boxes that was almost as tall as I was
2018-03-15T02:55:37 < jadew> when my fridge stopped working, I started using a cooling box (like the ones you take on picnics) and was stocking it with ice from the gas stop
2018-03-15T02:55:50 < jadew> lived like that for 4 years
2018-03-15T02:56:04 < Ultrasauce> depression really fucks people around
2018-03-15T02:56:20 < jadew> when winter was coming, my gf was saying that it's refrigerator season, because I could keep my stuff on the balcony
2018-03-15T02:56:51 < jadew> needless to say, I only ate fast food at home
2018-03-15T02:56:57 < branjb> lol
2018-03-15T02:56:58 < jadew> cooked food only when going out lol
2018-03-15T02:57:40 < jadew> I forgot my kitchen window open for a year and it got really dusty and nasty in there
2018-03-15T02:57:51 < jadew> the door had a glass window in it (really big one)
2018-03-15T02:58:00 < jadew> so I covered it

2018-03-15T03:00:25 < jadew> I forgot some laundry on the balcony for so long, that a pair of pigeons started a nest there
2018-03-15T03:01:13 < jadew> that was my early 20's tho, I'm the other way now
2018-03-15T03:01:58 < jadew> mainly because I moved in with my g/f and I coudln't do that crap anymore
2018-03-15T03:02:19 < jadew> she used to get pissed off about it and I was telling her that if it's bothering her, she should clean it
2018-03-15T03:02:24 < jadew> cuz it's not bothering me
2018-03-15T03:03:43 < jadew> then I realized I don't want her moving my stuff and misplacing it, so I did it myself
2018-03-15T03:04:24 < jadew> on top of that, I got more serious about electronics and I realized I can't find things when I need them if everything is a mess
2018-03-15T03:05:02 < jadew> so I guess you need two things for that to happen: not giving a crap and not needing to find tiny stuff all the time

2018-03-15T17:19:03 < blacktronics> when i disable interrupts during a certain part of code execution, and an interrupt does get triggered during that time, does it just get discarded or will it jump to the interrupt once interrupts are enabled again?

2018-03-15T18:07:34 < Thorn> interrupt request inputs, registered = have FFs on them
2018-03-15T18:07:47 < Thorn> it'd be more correct to say latched, so that they will stay active until serviced even if the actual IRQ input is cleared
2018-03-15T18:08:10 < Thorn> which is not the case with many interrupts, such as UART, SPI, timers etc.

2018-03-15T21:27:17 < BrainDamage> stuff like that always makes me think of the deresponsabilization that is pervasive in the IT industry
2018-03-15T21:27:50 < BrainDamage> if a bridge falls there's a clear chain of responsibility that reaches all the way to the engineer and hopefully the managers

2018-03-16T01:16:55 < blacktronics> Can be quite brittle though

2018-03-16T02:15:59 < jadew> blacktronics, but more elastic than PLA, right?
2018-03-16T02:16:33 < blacktronics> Oh yeah, also definitely stronger overall
2018-03-16T02:16:58 < blacktronics> PLA is at best good for figurines lol
2018-03-16T02:17:12 < blacktronics> I don't even have any, its useless to me
2018-03-16T02:17:40 < jadew> good thing I only bought two rolls then
2018-03-16T02:17:45 < jadew> I find it ok so far
2018-03-16T02:17:57 < jadew> but what do I know, I'm a noob
2018-03-16T02:20:10 < jadew> any ideas on what kind of tollerance I should leave between screw and nut when 3D printing them?
2018-03-16T02:20:18 < jadew> would 10% be a good value?
2018-03-16T02:20:28 < jadew> (the nut being 10% bigger)

2018-03-16T03:43:05 < blacktronics> yea i can send you settings that should work well
2018-03-16T03:43:10 < blacktronics> i am running an a8

2018-03-16T03:46:52 < Rob235> ok thanks, not sure what went wrong, I think if I raised my settings a little it would have come out a lot better, I think it was a little low and got a partial clog
2018-03-16T03:47:09 < Rob235> raised my temp*
2018-03-16T03:48:57 < blacktronics> ye petg tends to need more heat
2018-03-16T03:49:11 < blacktronics> also quite stringy usually
2018-03-16T03:49:54 < blacktronics> makes bridging work very well tho
2018-03-16T03:50:47 < Rob235> Might have to put some glue on the painters tape too
2018-03-16T03:50:59 < Rob235> I forget if I printed at 230 or 235, I'll try a temp tower with it tomorrow
2018-03-16T03:51:37 < Rob235> and faster retract speed
2018-03-16T03:55:51 < blacktronics> i never needed glue
2018-03-16T03:56:07 < blacktronics> some hairspray works excessively well tho
2018-03-16T03:56:20 < blacktronics> literally tape stuck to print afterwards

2018-03-16T04:37:07 < aandrew> mosfet driver board, got a decent boost converter on it to drive the fets hard
2018-03-16T04:37:27 < aandrew> the cap/resistor/diode/short between the driver and fet gate are for experimenting

2018-03-16T04:38:30 < aandrew> the funny thing is what I'm driving with these... fucking LEDs
2018-03-16T04:41:25 < dongs> weed growing pays
2018-03-16T04:41:45 < dongs> aandrew: do you even need that much current for gate drive
2018-03-16T04:41:57 < dongs> most gate driving boosts just use capacitor boost drivers
2018-03-16T04:42:00 < dongs> cuz you dont need lots of current??
2018-03-16T04:42:04 < dongs> and its cheap as fuck
2018-03-16T04:42:15 < dongs> whats your VIN
2018-03-16T04:42:23 < aandrew> the fets I'm driving probably don't, but the idea here is to overkill the shit and scale back
2018-03-16T04:42:32 < dongs> sounds dumb tho
2018-03-16T04:42:51 < aandrew> well it's easier to go overboard and scale back than it is to try to bodge in a bigger supply if you need it
2018-03-16T04:44:35 < dongs> CISS
2018-03-16T04:45:33 < aandrew> hm?
2018-03-16T04:46:53 < aandrew> got an example cap boost shit for smaller fets?
2018-03-16T04:46:59 < aandrew> I'll make a board with that too to test
2018-03-16T04:47:44 < dongs> trash china escs usually use some MAX charge-cap voltage doubler to take wahtever VCC to >= 12V for gate driver
2018-03-16T04:48:14 < dongs> lemme see ifI can find a random part#

2018-03-16T04:50:31 < dongs> 5V -> 10V or wahtever, the use case is generally you have 5V available on an esc which then gets doubled for gate drive

2018-03-16T04:52:23 < dongs> the actual current they will need to switch stuff will be comin from vboot voltage rail

2018-03-16T04:54:48 < jadew> I've been busy
2018-03-16T04:54:59 < jadew> oh
2018-03-16T04:55:03 < dongs> you can check the exact time by kikepedia edit history
2018-03-16T04:55:15 < dongs> because those no-lifes have nothing better to do than edit changing is -> was
2018-03-16T04:55:25 < dongs> aandrew: interesting, no separate vboot voltage eh
2018-03-16T04:55:47 < aandrew> no, and input vih/vil is independent of vcc which is cool
2018-03-16T04:56:27 < dongs> well thats normal
2018-03-16T05:00:46 < aandrew> yeah some of these mosfets have a couple thousand pF of capacitance
2018-03-16T05:00:57 < aandrew> need a lot of current to switch that shit quickly
2018-03-16T05:01:14 < aandrew> others have like 60pF
2018-03-16T05:01:27 < aandrew> the idea is to try different things and see what works acceptably and measure what the tradeoffs are
2018-03-16T05:01:33 < dongs> mkay
2018-03-16T05:03:16 < aandrew> most of these fets have vgsth of under 5V so it's unlikely I need anything fancy to drive them, but again that's the point of the board
2018-03-16T05:03:50 < aandrew> trying to put 3A through an LED for <100us, but if it takes 75us to ramp up the voltage then it's shit

2018-03-16T05:11:22 < aandrew> the MIC412x datasheet actually has some good docu

2018-03-16T05:13:44 < aandrew> blacktronics: I'm experienced in that world too, although much much larger power
2018-03-16T05:14:01 < aandrew> (>100kW usually)
2018-03-16T05:14:21 < blacktronics> sounds fun, high speed switching?

2018-03-16T05:14:45 < blacktronics> oh fun
2018-03-16T05:14:46 < aandrew> usually around 8kHz to minimize switching losses

2018-03-16T07:39:07 < dongs> when was the last tiem CUCKCAD got updated?
2018-03-16T07:39:12 < dongs> like 2 years ago
2018-03-16T07:39:32 < dongs> and if I'm talking about REAL update and not some behind-the-scenes-shit then probably decade ago

2018-03-16T07:42:57 < blacktronics> Yes
2018-03-16T07:42:57 < dongs> i didn't think anyone actually seriosuly used that
2018-03-16T07:43:11 < blacktronics> It was of the best
2018-03-16T07:43:19 < dongs> in 1996?
2018-03-16T07:43:24 < blacktronics> Yes
2018-03-16T07:43:32 < dongs> there was this dude in #stonertronics efnet who used some DOS layout trash
2018-03-16T07:43:36 < dongs> for years
2018-03-16T07:43:47 < blacktronics> Lol
2018-03-16T07:43:55 < dongs> then his work bought him altium
2018-03-16T07:43:57 < dongs> and he was like
2018-03-16T07:44:02 < dongs> what the FUck was i doing all tehse years
2018-03-16T07:44:11 < blacktronics> Haha
2018-03-16T07:44:43 < blacktronics> Altium feels bloated to me
2018-03-16T07:45:48 < blacktronics> Just go back to graph paper honestly
2018-03-16T07:50:46 < englishman> electrical tape and cellophane purists
2018-03-16T07:55:23 < dongs> well if altium feels bloated
2018-03-16T07:55:25 < dongs> try orcad
2018-03-16T07:55:37 < dongs> no less than 20 purchase options for every one of its 20+ separate programs
2018-03-16T07:56:17 < dongs> do you want to use OrCAD (tm) Layout (tm) With Low, Medium, or HighSpeed options? What about trace length? Do you want to be limited to 5cm, 10cm, or 50cm? Do you want to have manual parts placement or automatic?

2018-03-16T10:34:15 < dongs> nope, looks like they decided that was good
2018-03-16T10:34:27 < dongs> no more nudging label numbers by keyboard
2018-03-16T10:34:30 < dongs> auto-snaps to end of wire
2018-03-16T10:34:34 < dongs> fucking trash
2018-03-16T10:36:38 < dongs> i thought even mouse placing net names and shit was fucky
2018-03-16T10:36:43 < dongs> its like the snap to stuff became too hard
2018-03-16T10:37:21 < Steffanx> Are you talking about kicad or altium 18.1?
2018-03-16T10:38:22 < Steffanx> Damn, this german train is so old and dirty. I bet it was used in WOII foe transport.
2018-03-16T10:38:42 < Steffanx> For*
2018-03-16T10:39:09 < BrainDamage> oh wow, so you took the train, props for the courage
2018-03-16T10:40:36 < Steffanx> Yeah. Airplane is much hassle too. And then i still have to use the train
2018-03-16T10:43:44 < Steffanx> And i dont mind doing some sightseeing.
2018-03-16T10:50:48 < zyp> haha
2018-03-16T10:51:10 < zyp> shame I've got other plans this weekend, would have been fun to go
2018-03-16T10:52:01 < Steffanx> Why one needs courage for a train trip? First class <3
2018-03-16T10:53:03 < Steffanx> Sadly the weather is quite bad. Next week wouldve been better
2018-03-16T10:53:14 < BrainDamage> here's a fantastic day
2018-03-16T10:53:48 < zyp> first class to auschwitz
2018-03-16T10:53:49 < BrainDamage> the air temp is cold, but it rained this morning and the sun is very bright so everything shines
2018-03-16T10:54:07 < zyp> can't be that cold if it rained
2018-03-16T10:54:27 < BrainDamage> 2 days ago there was 20°C
2018-03-16T10:54:34 < BrainDamage> now it's 5°C
2018-03-16T10:54:54 < zyp> probably somewhere between 0 and -5 here
2018-03-16T10:54:57 < BrainDamage> and it's going to snow Sunday
2018-03-16T10:55:21 < Steffanx> Itll be rainy/snowy in tct land
2018-03-16T10:56:11 < Steffanx> This train doesnt even have wifi and the cellular connection here is terrible.
2018-03-16T10:56:22 < dongs> Steffanx: altidumb. why would i be using kikecad
2018-03-16T10:56:34 < zyp> dongs, because it sounded as bad as kicad
2018-03-16T10:56:38 < dongs> Lol
2018-03-16T10:56:53 < zyp> Steffanx, sounds like the typical norwegian train experience too
2018-03-16T10:57:05 < dongs> i took 5000 yen bus from osaka to fukuoka
2018-03-16T10:57:10 < dongs> nevar again
2018-03-16T10:57:11 < dongs> holy shit.
2018-03-16T10:57:12 < zyp> haha
2018-03-16T10:57:17 < dongs> overnight
2018-03-16T10:57:17 < Steffanx> Bus..
2018-03-16T10:57:18 < zyp> why the fuck
2018-03-16T10:57:20 < dongs> except i got zero sleep
2018-03-16T10:57:23 < dongs> zyp, 5000 yen thats why
2018-03-16T10:57:48 < dongs> i would have rather take the overnight train
2018-03-16T10:57:51 < dongs> but those don't exist anymore
2018-03-16T10:58:05 < zyp> didn't catch the last shinkansen or just too cheap for that?
2018-03-16T10:58:10 < dongs> the latter
2018-03-16T10:58:19 < dongs> i mean, shinkansen is 14000
2018-03-16T10:58:24 < dongs> gtfo
2018-03-16T10:58:37 < dongs> its cheaper to fly (literally, flights a few days ahead are like 4000-5000
2018-03-16T10:58:38 < Steffanx> How many km is that?
2018-03-16T10:58:41 < dongs> ~600
2018-03-16T10:58:48 < zyp> pretty sure I'd rather pay 14000 than take a fucking overnight bus
2018-03-16T10:58:56 < dongs> yes but i wasn't in a hurry
2018-03-16T10:58:57 < dongs> and now i know
2018-03-16T10:59:59 < Steffanx> Im glad i can sleep semi-everywhere. Except when there are yelling kids
2018-03-16T11:00:17 < dongs> im sure i could have slept on teh bus
2018-03-16T11:00:24 < zyp> I once flew from tokyo to nagoya and took the shinkansen back
2018-03-16T11:00:29 -!- c10ud [~c10ud@emesene/dictator/c10ud] has quit [Ping timeout: 276 seconds]
2018-03-16T11:00:35 < dongs> but the problem is, it was one of those super ghetto buses with barely any recline on the seats, and they were so close together i couldnt even stretch my legs
2018-03-16T11:00:36 < zyp> ended up about even in both time and money spent
2018-03-16T11:00:55 < dongs> yeah im sure
2018-03-16T11:01:09 < dongs> but fuck, jap transport is fucked
2018-03-16T11:01:35 < zyp> plane tickets were a bit cheaper, but getting to/from the airports ate up the difference
2018-03-16T11:03:13 < dongs> i bet gegtting to airport cost money too
2018-03-16T11:03:22 < zyp> that's what I said
2018-03-16T11:03:43 < dongs> ah, i thought you meant time-wise
2018-03-16T11:03:45 < dongs> but price-wise too
2018-03-16T11:03:48 < zyp> what surprises me is that shinkansen has to be that fucking expensive when they have enough passengers to justify a 16-carriage train between tokyo and osaka every ten minutes
2018-03-16T11:03:58 < zyp> yeah
2018-03-16T11:04:11 < zyp> that's why I took the shinkansen back
2018-03-16T11:04:25 < dongs> clearly the real price is the price of JR pass
2018-03-16T11:04:36 < dongs> anything above that is literally just japs fleecing japs
2018-03-16T11:04:44 < zyp> JR pass is nice
2018-03-16T11:04:52 < dongs> they can't be losing money on that
2018-03-16T11:04:55 < dongs> regardless
2018-03-16T11:05:09 < dongs> so i'd consider that the minimum require profit from shitkansen
2018-03-16T11:05:13 < zyp> well, depends how much the average user get out of it
2018-03-16T11:05:13 < dongs> required
2018-03-16T11:05:25 < dongs> if I got it, i would fucking make sure it gets used
2018-03-16T11:05:39 < dongs> i'd take trains up and down japan daily just to get my shit worth
2018-03-16T11:05:44 < zyp> I bet most people just go tokyo-osaka round trip, which isn't that much cheaper than the actual tickets
2018-03-16T11:06:48 < dongs> oh FUCKING WOW.
2018-03-16T11:06:56 < dongs> so the shit snapped to wrong pin (again)
2018-03-16T11:07:03 < dongs> and i try to nudge with keyboard
2018-03-16T11:07:10 < dongs> and it just snaps to next pin over
2018-03-16T11:07:13 < dongs> (wrong one again)
2018-03-16T11:07:13 < tct> Steffanx, status?
2018-03-16T11:07:15 < dongs> and can't move from there
2018-03-16T11:07:26 < tct> Steffanx, no yelling kids around here
2018-03-16T11:07:28 < zyp> what snapping are you talking about? in schematic?
2018-03-16T11:07:32 < dongs> yes
2018-03-16T11:07:36 < dongs> pn some net
2018-03-16T11:07:38 < dongs> on top of wire
2018-03-16T11:07:42 < dongs> then ctrl+arrow keys
2018-03-16T11:07:42 < zyp> aren't you using grid?
2018-03-16T11:07:44 < dongs> to move it around
2018-03-16T11:07:45 < dongs> of course I am
2018-03-16T11:08:01 < zyp> idk then
2018-03-16T11:08:13 < dongs> no, its definitely a regression in 18. shit
2018-03-16T11:08:27 < dongs> tho im sure altifuck considers it "enhancement"
2018-03-16T11:08:37 < zyp> good thing my subscription expired on AD15 then
2018-03-16T11:08:53 < dongs> yeah im defiitely considering not paying these fucks next year
2018-03-16T11:09:15 < dongs> removing FPGA trash was a plus but holy shit they've been adding aids on top of aids nonstop
2018-03-16T11:09:34 < zyp> the new multi board shit seems like it could be convenient
2018-03-16T11:09:56 < zyp> or maybe useless, hard to say without actually trying it

2018-03-16T14:57:27 < dongs> all the things that made it not fucking annoying are getting removed and/or bugged out
2018-03-16T14:58:52 < Steffanx> I love how they change major things
2018-03-16T14:59:05 < Steffanx> Why they do that? Someone complained about it
2018-03-16T14:59:09 < dongs> no
2018-03-16T14:59:18 < dongs> i guess they switched to some new toolkit for the UI
2018-03-16T14:59:22 < dongs> to allow this retarded theming trash
2018-03-16T14:59:28 < dongs> and they haven't hacked back in all the old shit
2018-03-16T14:59:35 < dongs> and/or it might not be possible
2018-03-16T14:59:40 < dongs> i.e. math in input boxes is gone too in 18
2018-03-16T14:59:46 < dongs> while it does work in some boxes on 17
2018-03-16T14:59:56 < Steffanx> :S
2018-03-16T15:00:04 < dongs> oh hey, math is back in 18.1 at least
2018-03-16T15:00:09 < dongs> i wonder if it works in ALl boxes
2018-03-16T15:00:19 < dongs> nope
2018-03-16T15:00:21 < dongs> still doesnt work in JL
2018-03-16T15:00:26 < dongs> which is where I'd need it the most
2018-03-16T15:00:32 < dongs> but at least works for part x/y location
2018-03-16T15:10:17 < dongs> another ragething is for some reason string boxes now have bullshit non-automatic dimensions
2018-03-16T15:10:29 < dongs> so when I ps a string and change it it becomes wrapped around some random sized box
2018-03-16T15:10:36 < dongs> and i have to go and width/ehight and enter new shit

2018-03-16T15:41:57 < Rob235> and fixed the couplers a bit, the two rods were touching

2018-03-16T16:25:15 < dongs> oh, speaking of youtube.. that feranec shit is somewhat useful
2018-03-16T16:25:19 < dongs> if you can handle his whining voice

2018-03-16T16:25:35 < dongs> i dono if enough of his free shit covers the basics
2018-03-16T16:25:42 < dongs> but there's some useful stuff there
2018-03-16T16:25:48 < Thorn> well Feranec also teaches proper routing, not just the software

2018-03-16T16:32:40 < dongs> with that shape?
2018-03-16T16:33:04 < dongs> i donno if they have proper boolean ops on regions now
2018-03-16T16:33:22 < tomeaton17> Okay guess I need to learn how to make custom pads then
2018-03-16T16:35:08 < aandrew> that doesn't look hard to make tomeaton17
2018-03-16T16:35:42 < aandrew> couple poly with plated holes maybe
2018-03-16T16:36:00 < dongs> i was thinking more the cut off ends
2018-03-16T16:36:08 < dongs> probably start off with an oval hole/pad of smaller outer size
2018-03-16T16:36:22 < dongs> then place a copper region on top of that and boolean subtract the slot
2018-03-16T16:36:22 < aandrew> dongs: polys
2018-03-16T16:36:40 < dongs> well you still need a plated hole for the center
2018-03-16T16:36:41 < aandrew> you could do that too, but like you said I don't know if altium has that capability
2018-03-16T16:36:44 < aandrew> what fucking part is that anyway
2018-03-16T16:36:54 < dongs> sounds like one of those current sensor shits

2018-03-16T16:38:36 < aandrew> aha
2018-03-16T16:38:41 < aandrew> bet that's a pretty penny
2018-03-16T16:38:56 < dongs> not saying thats the same part tomeaton17 got but it looked similar enough
2018-03-16T16:38:56 < aandrew> wonder if it's cheaper than a regular old piece of copper threaded through a LEM
2018-03-16T16:39:31 < aandrew> love how TI webbench still uses flash and the only browser that does a good job with it is IE
2018-03-16T16:39:31 < dongs> haha i was right
2018-03-16T16:39:34 < dongs> it literalyl IS that part
2018-03-16T16:39:37 < aandrew> heh
2018-03-16T16:39:42 < tomeaton17> it is indeed that little part
2018-03-16T16:39:47 < dongs> page 20 in datasheet
2018-03-16T16:39:52 < tomeaton17> but acs770 so better luck next time
2018-03-16T16:39:53 < tomeaton17> :p
2018-03-16T16:39:56 < dongs> :D
2018-03-16T16:40:09 < tomeaton17> yes its very expensive
2018-03-16T16:40:18 < tomeaton17> But in my design its in an add on module
2018-03-16T16:40:39 < tomeaton17> because the part itself its 5times more expensive then the base board lol
2018-03-16T16:40:48 < tomeaton17> but 200a +- is nice
2018-03-16T16:41:21 < dongs> there's boolean on regions
2018-03-16T16:41:25 < dongs> but probably need to read docs how to use it
2018-03-16T16:41:27 < sync> aandrew: it depends
2018-03-16T16:41:38 < dongs> the obvios thing of selecting both and doing subtract from menu probably wont work
2018-03-16T16:41:40 < sync> if you want to integrate your shit on a pcb it is more useful

2018-03-16T16:52:24 < dongs> tho I think i might redo it flipping thoser 2x8s vertical and make it fit into rageberry shape so i can use 4 screws to hold it in place
2018-03-16T16:52:25 < branjb> lol
2018-03-16T16:53:20 < branjb> rageberry's are great, no cheaper way to do basic shit

2018-03-16T16:53:38 < dongs> blinking 3 leds you can do with retarduino
2018-03-16T16:53:47 < branjb> ok, let me rephrase that
2018-03-16T16:53:49 < dongs> there's TONS of shit that uses rageberry for no good reason
2018-03-16T16:53:57 < branjb> no cheaper way to do shit that you need lunix for
2018-03-16T16:54:00 < tomeaton17> Like every door at my workplace :p
2018-03-16T16:54:17 < branjb> I use one to stream gcode to my CNC
2018-03-16T16:54:31 < tomeaton17> Yeah I need to try the boolean thingy, putting loads of regions lags my computer to shit
2018-03-16T16:56:42 < branjb> dongs you seen Rust on stm32?
2018-03-16T16:56:51 < dongs> sorry i'm not a faggot
2018-03-16T16:56:54 < dongs> so no
2018-03-16T16:57:05 < dongs> try o6, im sure he has :)
2018-03-16T16:57:14 < branjb> he was the one who told me about it
2018-03-16T16:58:17 < dongs> i bet
2018-03-16T16:59:10 < aandrew> fuck man it's a weird fucking world when this chan is more sane than lwz
2018-03-16T17:00:13 < aandrew> wtf stm32 discovery was it that had ethernet on it, I can't remember the chip now
2018-03-16T17:00:21 < aandrew> thoguht it was f407 or 417
2018-03-16T17:00:34 < branjb> was f429
2018-03-16T17:00:49 < dongs> aandrew: the Zi nucleo has it
2018-03-16T17:01:26 < branjb> http://www.st.com/en/evaluation-tools/nucleo-f429zi.html
2018-03-16T17:01:33 < dongs> yes that
2018-03-16T17:01:39 < dongs> thats the trash i was prototypign weith
2018-03-16T17:01:48 < dongs> better htan a 429 disco cuz it actually has most of hte pins open/usable
2018-03-16T17:02:02 < dongs> or wahtever disco it was that had a fucking 300pin STM on it and only retarduino headers for IO
2018-03-16T17:02:09 < branjb> lol
2018-03-16T17:04:48 < aandrew> 429 that was it thank you
2018-03-16T17:05:03 < aandrew> oh nucleo not discovery that's where I'm failing
2018-03-16T17:06:11 < tomeaton17> gave up on the footprint, computer keeps lagging out need to fix that

2018-03-16T17:10:51 < aandrew> morpho connector, that's what it's called
2018-03-16T17:10:59 < dongs> no
2018-03-16T17:11:02 < dongs> thats the 2x20pin one
2018-03-16T17:11:11 < dongs> the discunvery had only retardino on it
2018-03-16T17:11:50 < aandrew> right, but the nucleo board has the morpho connectors which is what I need to use to access most of the pins
2018-03-16T17:12:07 < aandrew> it's the nucleo 429 that or 7xx that I want to use which has teh ethernets

2018-03-16T17:13:26 < dongs> has anyone tried using any of advanced shit with mbed?
2018-03-16T17:13:34 < dongs> i mean just about everty fucking ST board says "mbed enabled"
2018-03-16T17:13:41 < dongs> but when I look at supporrted shit theres barely anything
2018-03-16T17:13:47 < dongs> sure you can blink led but thats about it
2018-03-16T17:15:49 < branjb> mbed is cancer that college students use because vendor libraries are too foreign to them
2018-03-16T17:15:52 < aandrew> yeah everything is mbed blah
2018-03-16T17:16:05 < aandrew> it's all part of the dumbing down of techs to make embedded shit easy
2018-03-16T17:16:55 < branjb> remember the hypermeme challenege that musk did a few years back? my schools team was one of the finalists and they had raspberry pi and mbed nucleo's all over their design
2018-03-16T17:17:23 < aandrew> heh
2018-03-16T17:17:31 < aandrew> I mean I really don't mind these boards for quick and dirty testing
2018-03-16T17:17:48 < aandrew> in fact I've really come around on Arduinos. I used to hate the fucking things but being able to knock something together real fast as a test is great
2018-03-16T17:17:58 < branjb> their design was going to be shot through a tube at 400+ mph with raspberry pi and nucleos at the helm
2018-03-16T17:18:03 < aandrew> but when you're embedding Sketch shit in final products something's gone terribly wrong with your desing

2018-03-17T03:16:02 < fenugrec> off-topic... has anyone noticed recently on ebay, there's a seller scam going one with "too good to be true" deals, but instead of an actual description, they show this BS http://vi.vipr.ebaydesc.com/ws/eBayISAPI.dll?ViewItemDescV4&item=183131210872
2018-03-17T03:16:21 < stvn> ebay is full of scams
2018-03-17T03:16:22 < englishman> ha
2018-03-17T03:16:38 < englishman> probably buying from each other to boost ratings
2018-03-17T03:16:44 < englishman> or to trick buying bots
2018-03-17T03:16:46 < fenugrec> what I don't get is how they apparently commandeer old seller accounts (this one over 10 years old) - I don't believe scammer have the foresight to do a 10 year buildup
2018-03-17T03:16:58 < stvn> I'll bring one out from the vault

2018-03-17T03:18:12 < fenugrec> but this is interesting - I mean, within a month I've seen at least 3-4 different sellers show up, each with 5-10 year old accounts, with the same ads, items and item photos
2018-03-17T03:18:58 < stvn> i'd suspect it has something to do with the gnaa

2018-03-17T07:53:56 < ohsix> i just got busier too hehe; guy i'd been doing a lot of work with, on his small electric car/trike, had been playing accordion for more than 60 years
2018-03-17T07:54:38 < ohsix> long story short he offered lessons to barter for servicing it, and got me a loaner accordion. i'm taking lessons now
2018-03-17T07:55:32 < ohsix> it's pretty wicked, given a choice i probably wouldn't learn the accordion, but in learning it i'm going to end up learning a lot of shit about music, reading and writing it; pitch stuff, knowing pitch by tone and stuff
2018-03-17T07:56:13 < ohsix> they're fun to play, and the bass reeds/matrix keyboard with the chords on it make it sound wicked

2018-03-17T08:01:44 < ohsix> oh yea; attached for quick ping on whether it is bad form to use a latex rubberband in place of original when you're repairing cassette mechanisms. belt kits are $$$, and i don't know the size w/o a few more hours of disassembly, otoh a bag of random sized rubberbands makes it easy to just try some
2018-03-17T08:03:11 < ohsix> only thing i can think of is that they'd stretch way too much under tension

2018-03-17T08:35:18 < dongs> you could DMA it or you could just capture it in IRQ and save
2018-03-17T08:35:35 < dongs> i did NEC IR remote on some F30x this way
2018-03-17T08:43:21 < misan> so 2 timers?  where the master is triggered by a falling edge - getting suspended - triggering another timer dma sampling the 66.5ms and enabling the first timer again once the counter is overflowing?
2018-03-17T08:43:42 < dongs> no just one TIM15 with CC1/CC2 triggering
2018-03-17T08:43:47 < dongs> well, is what i used
2018-03-17T08:43:57 < dongs> i didn't use DMA, too lazy.
2018-03-17T08:44:07 < dongs> you could trigger like you said probably yeah
2018-03-17T08:48:19 < dongs> input trigger, slavemode reset, enable masterslave
2018-03-17T08:48:23 < dongs> this is all on TIM15 (for me)
2018-03-17T08:48:40 < dongs> then I enabled CC1/CC2 interrupts and grabbed the pulse width and fed into IR RX state machine
2018-03-17T08:48:58 < dongs> and timer overflow was set to > length of IR pulse
2018-03-17T08:49:09 < dongs> so if i got update interrupt (overflow) it means shit timed out
2018-03-17T08:49:11 < dongs> worked out pretty well

2018-03-17T10:01:52 < misan> https://pastebin.com/pFCatDwn the interrupt is triggered once data is available but the data is completely wrong
2018-03-17T10:03:35 < misan> the stm32l073 should run at 38mhz, in order to get a 0.5ms sampling the pretimer divider should be 19000 (no?) I want to capture a 66.5ms burst (so I should get 128 cycles (well a bit more but I would like to get a pattern at least))
2018-03-17T10:09:09 < misan> https://pastebin.com/UGmukgMj that's the output if I press 1 button on the remote control
2018-03-17T10:09:14 < misan> absolutely not what I would expect

2018-03-17T10:42:27 < dongs> 38mhz?
2018-03-17T10:42:34 < dongs> where teh shit do you get that random speed
2018-03-17T10:44:11 < dongs> oh cube shit
2018-03-17T10:44:15 < dongs> nooo idea what that needs
2018-03-17T10:44:54 < misan> 38mhz is the APB clock
2018-03-17T10:45:24 < misan> sorry 32mhz
2018-03-17T10:45:25 < dongs> no it isnt
2018-03-17T10:45:28 < dongs> yeah thats more like it
2018-03-17T10:45:30 < misan> not 38
2018-03-17T10:45:40 < dongs> so if you're not sure (tho using cube, you should be fairly sure)
2018-03-17T10:45:43 < dongs> enable MCO and scope it
2018-03-17T10:45:47 < dongs> and see if you're getting expected mhz out.

2018-03-17T11:01:04 < misan> can anyone help me understanding the timers for capturing some IR signal? (I think I'm missing basic things, I'm also willing to pay...)

2018-03-17T11:01:36 < dongs> do you already have teh carrier removed? i.e. you have an IR receiver thing which strips 36khz or wahtever carrier
2018-03-17T11:01:37 < misan> my theoretical understanding of the stm32 timers do not match my practical experience with it :-(
2018-03-17T11:02:18 < misan> dongs: I would expect a constant pattern when I push a button on the remote control (I don't really care if the returned value is the keycode yet)
2018-03-17T11:02:34 < misan> the decoding of the returned raw samples is easy...
2018-03-17T11:02:49 < dongs> which remote protocol is it
2018-03-17T11:02:51 < dongs> therels like 20
2018-03-17T11:03:03 < dongs> it doesnt have to be constant at all
2018-03-17T11:03:16 < misan> NEC
2018-03-17T11:03:24 < dongs> some remotes have keycode + repeat keycode etc
2018-03-17T11:03:39 < dongs> so its same shit i've done already
2018-03-17T11:03:51 < misan> that one has a repeat code, but I don't care about the repeat code yet
2018-03-17T11:04:20 < misan> it would be enough to get a correct pattern if I push a button the details can be worked out afterwards
2018-03-17T11:04:33 < dongs> i have no idea how to do waht you want with cube, but setting up masterslavce/trigger stuff should be similar to stdperiph
2018-03-17T11:04:43 < dongs> there's also some appnotes on ST about using timers for this

2018-03-17T12:27:36 < dongs> as well as cube project sampels etc.
2018-03-17T12:27:38 < dongs> its not THAT hard.
2018-03-17T12:27:52 < misan> basically nothing really works as expected... why should I set a timer period if it is useless
2018-03-17T12:28:03 < dongs> because thats not what its for
2018-03-17T12:28:04 < misan> the dma burst always seems to be the same length

2018-03-17T16:39:02 < ReadErr> ran across this today lol
2018-03-17T16:39:29 < dongs> lol
2018-03-17T16:40:41 < dongs> does that just... cycle all sims in order and sends spam or something
2018-03-17T16:40:46 < ReadErr> guess its just some mux and an arduino + oled + ethernet or some thing
2018-03-17T16:41:00 < ReadErr> nah they use them for registering accounts
2018-03-17T16:41:10 < ReadErr> like ones that need a real #
2018-03-17T16:41:23 < ReadErr> its damn near impossible to register a gmail these days
2018-03-17T16:42:35 < ReadErr> pretty smart idea i guess just didnt know shit like this existed
2018-03-17T16:42:57 < ReadErr> lol you can see the esp on it
2018-03-17T16:42:58 < dongs> what is the idea i dont get it
2018-03-17T16:43:02 < dongs> yeah tis esp1488
2018-03-17T16:43:18 < ReadErr> so you know when you go to make a new gmail account
2018-03-17T16:43:23 < ReadErr> they require SMS
2018-03-17T16:43:33 < dongs> i havent made one in > 10 years but sure
2018-03-17T16:43:40 < ReadErr> well you can only use a real # like 2x
2018-03-17T16:43:51 < ReadErr> so they russians and shit set these up
2018-03-17T16:44:05 < ReadErr> just to receive a bunch of SMS msgs
2018-03-17T16:44:10 < dongs> so someone needs to buy 64 simcards with differtent numbers or what
2018-03-17T16:44:11 < ReadErr> and forward the codes back out
2018-03-17T16:44:20 < ReadErr> yup
2018-03-17T16:44:40 < dongs> and when you made 64 acccounts, wat do?
2018-03-17T16:44:48 < ReadErr> get more cards
2018-03-17T16:44:58 < ReadErr> they are selling these to people who run the 'basestations'
2018-03-17T16:45:11 < ReadErr> and get 50% of the total sale i guess
2018-03-17T16:45:34 < ReadErr> Total price of all codes for SIM card №21 is $7.3
2018-03-17T16:45:34 < ReadErr> So, your earn is $7.3 / 2 = $3.65 for 1 SIM card of UK
2018-03-17T16:45:40 < ReadErr> seems like too much work for nothing
2018-03-17T16:46:13 < dongs> i guess you could register all those 20-something shitty services
2018-03-17T16:46:14 < dongs> using one number
2018-03-17T16:46:19 < dongs> * 64
2018-03-17T16:46:27 < ReadErr> you can get an AT&T # for 1$
2018-03-17T16:46:38 < ReadErr> and buy the sim cards for like 50c on ebay
2018-03-17T16:46:46 < dongs> anyway looks like IoT is getting abused to do dumb shit

2018-03-17T19:18:38 < perole> I do that when cap is on other side, but trying to convert to having everything on top layer
2018-03-17T19:18:46 < perole> seems to be frowned upon
2018-03-17T19:19:33 < karlp> use teardrops because your pacakge supports it, not because it makes any particular difference amirite?
2018-03-17T19:20:38 < perole> there is some reason to use them, and saw in a video that a pcb house added them for you
2018-03-17T19:21:12 < englishman> use teardrops to ensure theres enough copper left after etching in those inner corners

2018-03-17T19:25:33 < englishman> 4 mils is like the smallest annular that a typical pcb place will want to work with
2018-03-17T19:25:37 < englishman> you can get 3 but you will pay
2018-03-17T19:25:41 < englishman> 5 is much easier
2018-03-17T19:26:03 < englishman> if you can afford 24mil vias then blow up your drills too to save money
2018-03-17T19:27:25 < englishman> 12mil and smaller they need aluminum backing to drill and use 1 drill per panel
2018-03-17T19:27:48 < englishman> 16mil and smaller is already much cheaper, 18+ is all the same
2018-03-17T19:28:00 < englishman> tho if you are just ordering chinapcb this doesnt really matter
2018-03-17T19:28:51 < perole> 0.3/0.6 has been my standard, tried a small board with 0.3/0.5 and looks ok - no complaints from manu

2018-03-17T20:48:44 < misan> I wonder why it'sn ot
2018-03-17T20:49:01 < misan> it's not possible to sample in a bitstream for a certain amount of time via dma and stm32f0
2018-03-17T20:49:14 < misan> that timer voodoo is nasty
2018-03-17T20:50:03 < misan> really no other option than using an external IR chip with that stupid cortex-m arm
2018-03-17T20:50:58 < misan> the more STM documentation I read the more frustrating it gets...
2018-03-17T20:52:12 < Cracki> f0 is the smallest with the least powerful peripherals...
2018-03-17T20:52:39 < misan> I'd at least expect it could to some slow burst read
2018-03-17T20:53:06 < misan> it probably can but those rubbish timers aren't explained anywhere the way I need them
2018-03-17T20:57:11 < Cracki> burst read from some GPIOs?
2018-03-17T20:57:39 < Cracki> what do you need? timer-triggered DMA request?
2018-03-17T20:57:55 < Cracki> DMA request with zero stride?
2018-03-17T20:58:04 < Cracki> *zero "input" stride
2018-03-17T20:59:18 < misan> "The clock source can be provided by other on-chip timers, using one of the 4 internal trigger inputs" ... nice to know the theory but what does that mean in practice with stm32cube how are those things done ... the documentation would be way better if it could include some small snippets
2018-03-17T20:59:58 < misan> I would like to read NEC remote control input with my stm32f0 evb
2018-03-17T21:00:03 < misan> the burst is 66.5ms
2018-03-17T21:00:47 < misan> well I would like to understand how to do those things in general ... the NEC protocol doesn't matter
2018-03-17T21:01:01 < misan> I want to read burst data and visualise the bit-pattern
2018-03-17T21:01:06 < misan> just like with an oscilloscope
2018-03-17T21:02:22 < Cracki> ah so you want a logic analyzer
2018-03-17T21:02:46 < Cracki> look for app notes or examples on repeated I/O reads
2018-03-17T21:04:52 < Cracki> perhaps this will give you ideas http://www.st.com/content/ccc/resource/technical/document/application_note/7a/88/df/e3/d3/36/40/29/DM00169730.pdf/files/DM00169730.pdf/jcr:content/translations/en.DM00169730.pdf
2018-03-17T21:05:40 < Cracki> there a single transfer is triggered by edges on a PIN, but I'm sure you can do that with a timer as well

2018-03-17T21:42:41 < PaulFertser> Triggers, timers etc are all described in the Reference Manual.
2018-03-17T21:44:15 < PaulFertser> So you have all the registers explained in the RM, and the library sources that tell you how this library manipulates them.

2018-03-18T01:47:27 < jadew> they were saying to set the oscilloscope to 0.05 V/div
2018-03-18T01:47:35 < jadew> but in this table there are two collumns
2018-03-18T01:48:06 < jadew> Oscilloscope setting: 0.05 V/div. and Actual Votls/div: 0.5 V (because of the 1:10 probe) lol
2018-03-18T01:49:44 < stvn> ok
2018-03-18T01:50:09 < stvn> are you trying to make a bomb or something?
2018-03-18T01:51:25 < jadew> just calibrating an instrument (I replaced something in it and now it requires calibration)
2018-03-18T01:54:27 < stvn> sounds like you're preparing a jihad to me
2018-03-18T01:56:41 < jadew> looks like a battlefield in here
2018-03-18T01:57:05 < jadew> turns out I need a very special attenuator for this step
2018-03-18T01:57:40 < jadew> ebay says 150 pounds

2018-03-18T01:58:11 < stvn> hows the lithium deuteride?
2018-03-18T01:58:20 < jadew> heh

2018-03-18T04:14:47 < misan> is it possible to trigger filling a dma on a certain preprogrammed pattern/pulse length? Eg. 4 Pulses P1 > 10k cycles P2 > 400 cycles, P3 > 400 cycles, P4 > 400 cycles?
2018-03-18T04:15:57 < dongs> the DMA buffer length is configurable
2018-03-18T04:16:18 < misan> that I know
2018-03-18T04:17:25 < misan> but if I read 32 pulses sometimes it's not aligned
2018-03-18T04:17:46 < dongs> i've told you to use timer overflow as reset of your pulse counter
2018-03-18T04:18:00 < ReadErr> anyone know about cellphone carrier unlock?
2018-03-18T04:18:08 < dongs> yeah, don't do it
2018-03-18T04:18:14 < ReadErr> like the mechanics behind it
2018-03-18T04:18:21 < ReadErr> is it bruteforcing keys ?
2018-03-18T04:18:23 < ReadErr> or what
2018-03-18T04:19:32 < Cracki> that's specific to the handset
2018-03-18T04:19:32 < dongs> no,. its carrier running some app/shit thats signed by manufacturer and flipping a bit that says "not locked to carrier"
2018-03-18T04:19:40 < Cracki> ^
2018-03-18T04:19:58 < ReadErr> so they have you hook it up over usb
2018-03-18T04:20:05 < ReadErr> can they emulate the carrier over usb somehow?
2018-03-18T04:20:31 < dongs> could be OTA, could be whatever. its irrelevant as only faggots buy carrier locked shit in the first place
2018-03-18T04:21:00 < ReadErr> samsung shit
2018-03-18T04:21:17 < ReadErr> so places will sell the service 'credits'

2018-03-18T05:04:10 < misan> I just read 2 pulses at the beginning (to determine if it's a new key or repeating)
2018-03-18T05:04:37 < misan> if it's a new key I have to read 31 pulses because the reconfiguration will eat 1 pulse

2018-03-18T14:11:08 < tct> let's say: "He took a shower the morning after"
2018-03-18T14:13:43 < invzim> allreet, net-ties are working
2018-03-18T14:13:48 < invzim> would be nice if they could be placed in internal layers
2018-03-18T14:14:10 < tct> what's a "net-tie"?
2018-03-18T14:14:45 < invzim> virtual 0 ohm resistor kindof
2018-03-18T14:15:10 < tct> "internal layer" sounds like PCB stuff. so 0 ohm resistor in a PCB copper layer? so a track?
2018-03-18T14:15:39 < invzim> let's say you have 3 different 3.3V rails, but want them separate without having to put a 0 ohm resistor on pcb
2018-03-18T14:17:29 < tct> go on
2018-03-18T14:17:41 < invzim> that's it :)
2018-03-18T14:17:52 < jpa-> why do you want them separate?
2018-03-18T14:18:01 < tct> o.O
2018-03-18T14:18:08 < tct> invzim, got a pic or something?
2018-03-18T14:18:12 < tct> invzim, I never ever heard of that
2018-03-18T14:18:24 < invzim> me neither until yesterday when almighty dongs pointed me to them
2018-03-18T14:18:49 < jpa-> even kicad has them :P
2018-03-18T14:18:59 < tct> wtf
2018-03-18T14:19:01 < tct> why have I never heard of that
2018-03-18T14:19:07 < tct> or is that just called differently in this time zone?
2018-03-18T14:19:11 < jpa-> https://www.smtnet.com/library/files/upload/NetTies-and-How-to-Use-Them.pdf
2018-03-18T14:19:29 < jpa-> but i'd say that most of the time i've seen people use net ties, they'd have been better of not doing it
2018-03-18T14:19:31 < invzim> apart from layout stuff, it's nice to have the net names specific when doing layout and decoupling
2018-03-18T14:19:46 < tct> oooooh, those things
2018-03-18T14:19:47 < tct> lol
2018-03-18T14:21:45 < dongs> invDONGS can't you just stick a feerit bead between different 3V rails to separate them
2018-03-18T14:22:01 < jpa-> invzim: i don't quite follow you there, why would you want to layout and decouple them separately?
2018-03-18T14:22:05 < dongs> i mean thats how you usually do it anyway
2018-03-18T14:22:10 < jpa-> i.e. why don't you just have a single 3.3V rail
2018-03-18T14:22:43 < dongs> you have 3V3 from pwoer supply, then you go bead -> 3V3_Digital bead-> 3V3_Analog or wahtever the fuck
2018-03-18T14:23:11 < tct> yep, doing that often here as well. But never used a net tie, just a bead
2018-03-18T14:23:25 < jpa-> yeah, and if you don't separate them with a filter/bead, separating the layout seems quite useless

2018-03-18T14:24:12 < invzim> similar stuff on the ADC
2018-03-18T14:24:27 < tct> does not really answer the question
2018-03-18T14:24:29 < tct> (imho)
2018-03-18T14:24:36 < dongs> invzim: yeah, and all those are generally linked through a bead
2018-03-18T14:24:45 < dongs> 1V2 -> bead -> 1V2_VCCINT
2018-03-18T14:24:47 < dongs> or wahtever.
2018-03-18T14:25:04 < invzim> I want to treat and layout the PLL supply differently than VCCINT
2018-03-18T14:25:19 < dongs> good?
2018-03-18T14:25:20 < tct> can't you just do that when using a bead as well?
2018-03-18T14:25:30 < invzim> then it would be one bead pr rail
2018-03-18T14:25:32 < tct> I mean you have two separate nets with a bead
2018-03-18T14:26:05 < invzim> so yes you could, design is verified woth 0 ohm resistors so I would like to get rid of them
2018-03-18T14:26:47 < invzim> trying to move all passives from bottom to top of board, looks like someone barfed on it so skinning out stuff that's not needed

2018-03-18T14:30:14 < dongs> its fucking insane, pins everywhere
2018-03-18T14:30:19 < dongs> all over the package
2018-03-18T14:30:41 < tct> dongs, talk to zyp about it :p
2018-03-18T14:30:58 < dongs> zyp did sdram on some LPC, it looked less insane
2018-03-18T14:31:33 < tct> yeah, but he did some SDRAM+NAND on an F407 few weeks ago
2018-03-18T14:31:41 < dongs> oh?

2018-03-18T14:33:37 < tct> yes
2018-03-18T14:33:42 < dongs> that doesnt look length matched at all
2018-03-18T14:33:52 < dongs> which is probly ok for slow-ass sdr
2018-03-18T14:34:02 < dongs> and that routing looks similar to my shit
2018-03-18T14:34:16 < tct> zyp said it will be fine :)
2018-03-18T14:34:21 < tct> #ZypApproved
2018-03-18T14:34:21 < dongs> it will be
2018-03-18T14:34:37 < tct> the SRAM works fine. But haven't bothered with the NAND yet. Never used that interface.
2018-03-18T14:34:51 < dongs> sram or sdr?
2018-03-18T14:34:55 < jpa-> does F407 even have SDRAM support?
2018-03-18T14:35:03 < dongs> 07 doesnt
2018-03-18T14:35:07 < dongs> 27 or 29 does
2018-03-18T14:35:10 < jpa-> yeah
2018-03-18T14:36:51 < tct> dongs, the fuck is sdr?
2018-03-18T14:36:55 < tct> dongs, so sram
2018-03-18T14:36:58 < dongs> sdram, nigger
2018-03-18T14:37:07 < jpa-> single data rate sdram, as opposed to ddr sdram
2018-03-18T14:37:13 < tct> aah
2018-03-18T14:37:17 < tct> f407 doesn't do that
2018-03-18T14:37:43 < jpa-> so whole discussion has been about something totally different than what dongs was talking about :P
2018-03-18T14:38:07 < tct> ah shit, I didn't notice dong's 'D' in his posts
2018-03-18T14:38:17 < tct> sorry :p
2018-03-18T14:38:54 < jpa-> F407 seems pretty old for new boards!
2018-03-18T14:39:53 < tct> needed to get something done in very little time. So I decided to take what I know best. Also, fw development started before hw development and was based on an Olimex E407. I tried to keep surprises as unlikely as possible. This board worked 100% on the first try
2018-03-18T14:40:15 < jpa-> how boringly predictable
2018-03-18T14:40:30 < tct> "I like stability in my life" ;-)
2018-03-18T14:41:16 < jpa-> i have one work project where we run same firmware on STM32F427 and STM32F407, so i guess you can just upgrade later if any need arises
2018-03-18T14:42:40 < tct> that sounds great. Never checked out the 27, only the 29. What does the 27 offer over the 07?
2018-03-18T14:42:47 < tct> (as a drop-in replacement)
2018-03-18T14:42:58 < jpa-> more ram, more flash
2018-03-18T14:43:07 < Steffanx> Moar speed?
2018-03-18T14:43:17 < jpa-> that too, though only a few MHz
2018-03-18T14:43:53 < Steffanx> 12 is more than a few sir

2018-03-18T15:29:23 < kakimir> how do you interface hdmi?

2018-03-18T15:31:20 < jpa-> and not like anyone has made a rgb-to-hdmi chip
2018-03-18T15:31:27 < dongs> yeah
2018-03-18T15:32:18 < kakimir> but what chip exactly

2018-03-18T16:13:55 < zyp> dongs, as long as it's SDR, length matching shouldn't be very critical
2018-03-18T16:15:30 < zyp> at ~100mhz, a bit-time is still a couple of meters in length, so some millimeters of mismatch is not gonna matter
2018-03-18T16:17:33 < jpa-> capacitance mismatch would probably give a larger difference than length at these freqs

2018-03-18T18:14:02 < Cracki> wat
2018-03-18T18:14:37 < Cracki> at least it's not berlin
2018-03-18T18:14:51 < Steffanx> Like garbage EVERYWHERE
2018-03-18T18:15:03 < Cracki> ah you mean that? those are not germans doing it.
2018-03-18T18:15:26 < Cracki> my backyard is quite bare btw, just asphalt and garages
2018-03-18T18:16:09 < Cracki> germans are orderly. they rat you out to the landlord if you put your garbage out for pickup too early.
2018-03-18T18:16:48 < Cracki> all that garbage is due to others.
2018-03-18T18:16:55 < Steffanx> Sure sure :P

2018-03-18T18:18:06 < Cracki> good for you
2018-03-18T18:18:17 < Steffanx> So, its probably just around the tracks
2018-03-18T18:18:32 < Cracki> maybe, maybe not :P
2018-03-18T18:18:48 < Steffanx> No one sane would go live so close to the rail road
2018-03-18T18:19:10 < Cracki> germans have the best noise-isolating window technology
2018-03-18T18:19:16 < Steffanx> Except for swissers
2018-03-18T18:19:38 < Steffanx> But the houses seem to be f-ing old
2018-03-18T18:19:40 < Cracki> well of course, you have to shut up the cuckoo while it's _inside_ the clock
2018-03-18T18:20:13 < Cracki> that's europe. solid stone houses. the one I'm living in was built around 1900.
2018-03-18T18:20:36 < Cracki> all you have to renovate is the floors, they're made of wood beams
2018-03-18T18:21:45 < Cracki> if you wanna see new houses in germany, ask around. they're earmarked for the "new arrivals"
2018-03-18T18:24:17 < Steffanx> Ill visit dresden then. All made after 1945 :P
2018-03-18T18:24:41 < Cracki> ;)
2018-03-18T18:25:03 < Cracki> imho regular bombings improve cities. you get more space for roads, more space to grow.
2018-03-18T18:25:22 < Steffanx> *build
2018-03-18T18:26:27 < kakimir> yes
2018-03-18T18:26:29 < Cracki> right now I live in a goddamn tiny "spa city" (pop 250k, 40-50k due to a good tech uni) with single lane roads almost everywhere, that thinks it can get by with busses. they *buried* their tram tracks!
2018-03-18T18:27:23 < Cracki> some well placed "deconstruction" would open this place up for less clown-like public transport
2018-03-18T18:28:05 < kakimir> what country?
2018-03-18T18:28:07 < Steffanx> Time for a local "bomb" party.
2018-03-18T18:28:14 < kakimir> single line roads.. must be europe
2018-03-18T18:28:17 < Cracki> I can recommend southern germany. less leftist. more orderly.
2018-03-18T18:28:17 < Steffanx> Germland.
2018-03-18T18:28:37 < Cracki> well, "old towns".
2018-03-18T18:28:48 < kakimir> city council should be active and just demolish a lot of shit
2018-03-18T18:28:49 < Cracki> made for horsed carriages.

2018-03-18T18:30:49 < Cracki> if you're in the south, see about getting a Schweinshaxe
2018-03-18T18:31:41 < kakimir> what is spa city anyway?
2018-03-18T18:31:44 < Cracki> even the kebab is better in the south. forget kebab in the west (cologne).
2018-03-18T18:31:56 < Cracki> spa city is anything that's called "Bad ..."
2018-03-18T18:32:03 < Cracki> we have vulcanic hot springs here

2018-03-18T18:42:51 < Steffanx> Except that we hardly have those in dutchland. For some reason dutchies have/had a very destuctive mindset.

2018-03-18T18:45:12 < Cracki> europeans love their paved sidewalks. the pallets of stones can just be put on the ground one square meter at a time.

2018-03-19T00:58:10 < jadew> also the first print that failed terribly
2018-03-19T00:59:02 < jadew> I made it so it's screwable and some of the thread layers didn't have anything to stand on

2018-03-19T01:04:52 < zyp> square threads?
2018-03-19T01:04:57 < zyp> use tapered threads instead
2018-03-19T01:05:13 < jadew> triangular threads
2018-03-19T01:05:44 < zyp> those should print fine, no?
2018-03-19T01:05:49 < jadew> made them too long I guess, but it worked in a previous version
2018-03-19T01:06:07 < jadew> they printed fine the first time, then I changed the wall thickness (behind the thread) and it stopped printing
2018-03-19T01:06:13 < jadew> I think the slicer started doing something weird
2018-03-19T01:06:35 < jadew> lowering the layer height fixed the issue eventually
2018-03-19T01:06:42 < jadew> but not before trying the print a couple more times
2018-03-19T01:07:06 < jadew> also, I didn't get a hang of the needed tollerances yet
2018-03-19T01:07:27 < jadew> the first one I did didn't screw in because the male thread was too big
2018-03-19T01:07:45 < jadew> that's when I changed the wall thickness on the female one and the problems started
2018-03-19T01:07:56 < jadew> once it printed it turned out it was a bit too loose
2018-03-19T01:08:11 < jadew> but it still tightened fine

2018-03-19T01:09:22 < jadew> a tollerance of 20% of the thread bite in the diameter of the female thread seems to be too much
2018-03-19T01:09:30 < jadew> I probably shouldn't base on the thread bite tho
2018-03-19T01:10:36 < jadew> doesn't seem much... the thread bite is 2 mm
2018-03-19T01:16:45 < jadew> http://5.12.10.153/stuff/20180319_011127.jpg
2018-03-19T01:17:09 < jadew> that's the one that was too tight
2018-03-19T01:17:31 < jadew> then after reducing the wall thickness (making the inner radius higher) this started happening: http://5.12.10.153/stuff/20180319_011249.jpg
2018-03-19T01:17:36 < jadew> everything else was the same
2018-03-19T01:17:55 < jadew> so I assume it had something to do with the way it got sliced
2018-03-19T01:24:08 < Steffanx> Dont you look at the slice job before you print jadew ?
2018-03-19T01:25:02 < jadew> I do, but how could you tell that this is what is going to happen?
2018-03-19T01:25:08 < jadew> the one before worked just fine
2018-03-19T01:26:00 < jadew> and btw, you were right, it's fun doing things for the printer

2018-03-19T02:10:01 < Thorn> has anyone tried to measure edge rise times for different gpio drive strengths?
2018-03-19T02:10:33 < Thorn> is there a significant difference between 'low' and very high'
2018-03-19T02:10:59 < Cracki> they're prolly in the data sheet to specific models
2018-03-19T02:11:37 < Cracki> also if you're worrying about rise times, you want to worry about impedance and termination and all that stuff too
2018-03-19T02:11:45 < Cracki> hook it up to a scope and see
2018-03-19T02:12:22 < Cracki> "slew rate" is a term you might wanna grep for too
2018-03-19T02:13:00 < Cracki> the point of lower drive strengths is to reduce EMI
2018-03-19T02:15:53 < zyp> datasheet has it defined
2018-03-19T02:16:11 < zyp> t_f(IO)out and t_r(IO)out
2018-03-19T02:16:45 < zyp> though, the one I opened (f407 DS rev 4) has them all specified as TBD, just specifies maximum freqs
2018-03-19T02:18:08 < zyp> and they are naturally given for a given capacitance, since capacitance will affect the times
2018-03-19T02:18:28 < Thorn> lol f407 is an old part
2018-03-19T02:18:49 < Thorn> gj ST, still TBD
2018-03-19T02:18:58 < zyp> rev 4 is probably also old, I just opened whatever I had saved
2018-03-19T02:19:26 < zyp> current rev is rev 8

2018-03-19T02:21:57 < zyp> well, duh
2018-03-19T02:22:21 < zyp> there wouldn't be any point in varying the drive strength if it didn't actually make a significant difference

2018-03-19T03:39:34 < jadew> what I found weird is that I had two a couple of similar prints before that didn't fail
2018-03-19T03:39:46 < Cracki> slower?
2018-03-19T03:39:52 < Cracki> underextrusion can cause this too
2018-03-19T03:39:52 < jadew> nope, full speed
2018-03-19T03:40:03 < Cracki> _identical_ settings and gcode?
2018-03-19T03:40:05 < jadew> it started to fail the moment I made the change to the wall thickness
2018-03-19T03:40:08 < Cracki> nvm, "similar"
2018-03-19T03:40:16 < jadew> identical settings
2018-03-19T03:40:19 < Cracki> wall thickness from what to what?
2018-03-19T03:40:37 < jadew> from 2mm to 1.5 or something like that
2018-03-19T03:40:47 < Cracki> "nozzle" size?
2018-03-19T03:40:54 < jadew> .4
2018-03-19T03:40:57 < jadew> I think
2018-03-19T03:40:58 < Cracki> there you have it
2018-03-19T03:41:10 < Cracki> walls need to be multiples of nozzle size, or else you get empty space from the slider
2018-03-19T03:41:10 < jadew> that's the most common one, right?
2018-03-19T03:41:11 < Cracki> *slicer
2018-03-19T03:41:17 < Cracki> .4 is pretty standard
2018-03-19T03:41:22 < jadew> ah! that makes sense
2018-03-19T03:41:30 < jadew> so it was sticking to empty space
2018-03-19T03:41:37 < Cracki> look at what it sliced
2018-03-19T03:41:39 < Cracki> you'll see
2018-03-19T03:41:53 < jadew> I don't have it anymore
2018-03-19T03:42:04 < Cracki> .4 * 5 is 2, but 1.5 would have been sliced as .4 * 3 + .3 empty
2018-03-19T03:42:09 < jadew> yeah

2018-03-19T03:42:37 < Cracki> also, "nozzle size" doesn't really depend on physical nozzle size
2018-03-19T03:42:37 < jadew> how thick layers do you think you can have?
2018-03-19T03:42:57 < jadew> Cracki, what do you mean?
2018-03-19T03:43:13 < Cracki> what you have is filament going in, getting melted, and getting extruded into an ideal "bar" of height (z) * width (nozzle) * length (print speed)
2018-03-19T03:43:55 < Cracki> for a 0.4mm nozzle, I'd work with at most 0.2mm layers
2018-03-19T03:44:11 < Cracki> 0.3 might work, if you're adventurous or set the "nozzle size" to something wide
2018-03-19T03:44:16 < jadew> hmm, I've been printing 0.35mm layers fine
2018-03-19T03:44:21 < Cracki> then it'll squeeze out and smush flat the plastic
2018-03-19T03:44:32 < Cracki> hah good luck with that, not for overhangs
2018-03-19T03:44:34 < jadew> like, they look really good
2018-03-19T03:44:37 < Cracki> hmmm
2018-03-19T03:44:43 < jadew> oh, overhangs too
2018-03-19T03:44:45 < Cracki> good heating then, no underextrusion
2018-03-19T03:45:09 < jadew> I had overhangs at lower than 45 degrees
2018-03-19T03:45:14 < jadew> circular overhangs tho
2018-03-19T03:45:17 < Cracki> I have experience with an UM2 only. these things have weak filament heating
2018-03-19T03:45:51 < Cracki> ("hot end" I think is the term?)
2018-03-19T03:46:23 < jadew> probably, I'm new to this
2018-03-19T03:47:03 < Cracki> I'm more of a friend of resin lithography and sintering approaches (laser or HP's ink-based approach)
2018-03-19T03:47:19 < Cracki> but those are fucken expensive and need more maintenance
2018-03-19T03:48:27 < jadew> aren't resin prints weak?
2018-03-19T03:49:44 < Cracki> not that I've heard of
2018-03-19T03:50:00 < Cracki> they like some UV curing after they're done
2018-03-19T03:50:14 < Cracki> (put them in the sun for a bit)
2018-03-19T03:50:54 < Cracki> perfect layer fusion. around 0.02mm layer height and such
2018-03-19T03:51:25 < Cracki> still vector/plotter-based, so can be kinda slow, if you have an underpowered laser or sluggish mirror assembly
2018-03-19T03:51:27 < jadew> so far I'm happy with my PLA prints
2018-03-19T03:51:44 < Cracki> oh yes, I like PLA too. just fine for lots of mechanical stuff.
2018-03-19T03:51:47 < jadew> I think I'll graduate to PETG soon

2018-03-19T03:54:39 < Cracki> depends. they're messier (liquids that can get exposed if you don't store properly), the "vat" needs to be right
2018-03-19T03:55:01 < Cracki> the laser+mirror stuff needs to be calibrated or trimmed right, afaik
2018-03-19T03:55:39 < Cracki> there are a lot fewer DIYs around, so you still have the (semi)commercial prices you also had for FDM printers.
2018-03-19T03:56:39 < Cracki> in principle they have more potential than FDM because "contactless"
2018-03-19T03:57:05 < Cracki> also there's a company using DLP projection units to expose a whole frame at once, so rasterizing instead of drawing vectors
2018-03-19T03:57:39 < jadew> neat
2018-03-19T03:58:14 < Cracki> they continuously pull the print. there's no ablation movement because their vat has an oxygen-permeable glass that keeps the resin from polymerizing right at the interface to the glass
2018-03-19T03:58:16 < jadew> those would have to be some amazing projectors tho
2018-03-19T03:58:20 < Cracki> nah
2018-03-19T03:58:44 < Cracki> just the DLP unit + (reasonably homogeneous) UV light source
2018-03-19T03:58:52 < Cracki> those DLP things can be had "cheap"
2018-03-19T04:00:02 < Cracki> if you take a fullhd mirror array, that's 1080 on the short side, and for a 200mm area, would figure to 0.2mm
2018-03-19T04:00:34 < Cracki> that's still a bit steppy, but by pure optics, it'll blur a bit
2018-03-19T04:00:53 < Cracki> use higher-res arrays and smaller build area, or tile the build area with multiple arrays

2018-03-19T04:02:41 < Cracki> HP has this sintering stuff... they fill the volume with PHA powder, then print black ink and (basically) water on it, then shine some strong IR/heat on it
2018-03-19T04:03:46 < Cracki> print volume is heated to just below melting, black ink heats up from the extra IR light, just enough to get over melting, the "water" makes sure the contours stay sharp by cooling
2018-03-19T04:04:55 < Cracki> a layer every 5-10 seconds or so. build area is maybe 1-4 square feet, and however deep the trolley is
2018-03-19T04:06:06 < Cracki> huge apparatus. and another one beside it for pulling the objects out of the powder, brush them clean, and suck up the powder to recycle it.

2018-03-19T06:12:00 < blacktronics> they're a bit too large
2018-03-19T06:12:03 < blacktronics> only need 4 pins
2018-03-19T06:12:08 < fenugrec> if you had omitted "cheap" I would've said Canon plug
2018-03-19T06:12:34 < fenugrec> CB mic style can do 4 pins, I forget the real name
2018-03-19T06:12:45 < blacktronics> DMX/XLR?
2018-03-19T06:12:58 < blacktronics> i have no clue what they are called either tbh
2018-03-19T06:13:08 < blacktronics> but they are way too pricy and overkill for what i need
2018-03-19T06:13:09 < fenugrec> nah I'm thinking of something else
2018-03-19T06:13:12 < fenugrec> XLR is nice but 4-pin XLR won't be cheap
2018-03-19T06:13:29 < blacktronics> There are the cheapass GX16 and GX12
2018-03-19T06:13:43 < blacktronics> but they only have plugs and sockets, no female plugs

2018-03-19T07:06:03 < aandrew> stm32 ADC - can it be configured to wait for a trigger (EXTADC I know) but then sample as fast as it can for 'x' samples or until y timer or something?

2018-03-19T07:09:27 < aandrew> that's exactly what I was thinking, I didn't know if the ADC could switch from external trigger to self-trigger
2018-03-19T07:09:43 < emeb_mac> probably not
2018-03-19T07:09:54 < emeb_mac> more like trigger the timer
2018-03-19T07:11:33 < emeb_mac> how much latency can you stand from the trigger event to the first sample?
2018-03-19T07:11:54 < aandrew> actually nevermind
2018-03-19T07:12:12 < aandrew> I have an FPGA providing the first trigger pulse, and I forgot that all ADCs run off the same trigger

2018-03-19T13:53:50 < dongs> always difficult
2018-03-19T13:54:46 < dongs> < catphish> PCB ready for inverter components (and an stm32 dev board): https://imgur.com/a/JyI1A
2018-03-19T13:54:50 < dongs> is this kikecad
2018-03-19T13:54:52 < dongs> oh it is
2018-03-19T13:56:22 < dongs> Frans-Willem: beep
2018-03-19T13:58:00 < zyp> dongs, any progress on figuring out how much I owe you?
2018-03-19T13:58:08 < catphish> dongs: yes kicad
2018-03-19T13:58:24 < qyx> what are those things similar to sparkgaps
2018-03-19T13:58:43 < qyx> D1, D2, D3
2018-03-19T13:58:45 < qyx> uhm, diodes?
2018-03-19T13:59:12 < catphish> yes diodes, the pad is called SMA_SMB_UNIVERSAL_HANDSOLDER
2018-03-19T13:59:12 < dongs> Frans-Willem: zyp, no. also seems no progress on your 1st EMS either
2018-03-19T13:59:15 < catphish> or something liek that
2018-03-19T13:59:19 < dongs> im calling tomrorwo about some other crap, i will also mention this
2018-03-19T13:59:35 < zyp> dongs, like mentioned, 1st EMS arrived norwegian customs today
2018-03-19T13:59:39 < zyp> so I expect I have it tomorrow
2018-03-19T13:59:39 < catphish> its a nice big pad that fits all kinds of diodes :)
2018-03-19T13:59:43 < dongs> oh did it?
2018-03-19T13:59:52 < zyp> yeah
2018-03-19T13:59:53 < dongs> jap shit still shows as no update. i didnt bother cchecking norgepost
2018-03-19T13:59:54 < dongs> great!
2018-03-19T14:00:26 < zyp> catphish, looks kinda big for just a bootstrap diode though
2018-03-19T14:00:46 < catphish> actually the diode is much smaller than that universal pad
2018-03-19T14:01:09 < catphish> the diode is sma, but since i'm prototyping and the universal pad exists, i use it
2018-03-19T14:02:27 < dongs> < zyp> dongs, I was about to ask you how you handle lost packages, but now I see that ems package got tracked at import handling half an hour ago
2018-03-19T14:02:30 < dongs> oh i missed this
2018-03-19T14:02:32 < dongs> ok
2018-03-19T14:03:40 < zyp> so shit's arriving, now I just need to pay for it :p
2018-03-19T14:05:02 < dongs> cool
2018-03-19T14:05:05 < dongs> ill figure something out next week
2018-03-19T14:05:08 < dongs> er this week
2018-03-19T14:05:51 < zyp> good
2018-03-19T14:19:10 < catphish> dongs: https://nutty.tk/inverter3.pdf that's the schematic btw
2018-03-19T14:19:22 < catphish> it's a pretty standard inverter setup really
2018-03-19T14:21:55 < catphish> i mostly want to play with the current sensing
2018-03-19T14:22:58 < dongs> why F7-whateveR? bceause or HRTIM?
2018-03-19T14:47:47 < catphish> me?
2018-03-19T14:52:14 < karlp> tehy're suing l4, not f7
2018-03-19T14:54:42 < catphish> i'm using l4, honestly it wasn't chosen with any care at all, i saw the nucleo board was cheap, the chip had a lot of features, so i thought i'd use it, it wasn't until later that i looked more into the stm32 range
2018-03-19T15:01:45 < kakimir> fukin woke up and threw my laptop to floor headphone jack first
2018-03-19T15:02:18 < kakimir> maybe I thought it was a alarm clock
2018-03-19T15:02:26 < Steffanx> dont sleep with your laptop. Easy.
2018-03-19T15:02:28 < kakimir> *an
2018-03-19T15:03:14 < srk> kakimir: my jack is also broken so I'm using f4disco as a soundcard right now :D
2018-03-19T15:03:30 < kakimir> I need to test if my laptop jack is okay
2018-03-19T15:03:40 < kakimir> it is
2018-03-19T15:03:52 < kakimir> totally fuked my akg long lead
2018-03-19T15:07:26 < kakimir> it's like in 30degree angle
2018-03-19T15:07:46 < Steffanx> The jack of your akg?
2018-03-19T15:14:56 < kakimir> yes
2018-03-19T15:15:35 < kakimir> it probs came off a little and then bent
2018-03-19T15:16:04 < kakimir> my laptop is a beast I have dropped it to concrete wall too
2018-03-19T15:16:13 < kakimir> corner first
2018-03-19T15:16:32 < kakimir> huge dent but all good
2018-03-19T15:17:09 < Steffanx> How you even manage to do that?
2018-03-19T15:18:39 < jpa-> kakimir lives so high up north that gravity is horizontal there
2018-03-19T15:21:03 < kakimir> Steffanx, I was carrying it in a basket and I threw a heavy thing in there and the laptop jumped off

2018-03-19T15:42:36 < hdt551> Please help interpreting a diagram in the RM0390 ref manual about I2S on a stm32f446 I2S Philips Standard, page 874, figure 316
2018-03-19T15:43:15 < hdt551> The way I read this diagram, it doesn't seem like it follows the standard or
2018-03-19T15:43:15 < hdt551> at least what I see on a number of other DAC codec ic's.  The SD line shows
2018-03-19T15:43:15 < hdt551> MSB for the left channel starting one clock after WS goes low. That seems correct (except I think WS
2018-03-19T15:43:15 < hdt551> is supposed to go high not low).
2018-03-19T15:43:28 < hdt551> However, when the MSB starts for the right channel I think there is also supposed to
2018-03-19T15:43:28 < hdt551> be a one clock delay but ST doesn't show that.  Am I misreading this?

2018-03-19T15:49:04 < Cracki> philips quirk maybe
2018-03-19T15:49:15 < hdt551> In latest rev it should be figure 318
2018-03-19T15:49:42 < Thorn> 319
2018-03-19T15:49:44 < Cracki> sampled on rising edge, eh?
2018-03-19T15:50:13 < hdt551> I have tried both.
2018-03-19T15:50:14 < Cracki> so they have a delay of one sample to detect when the channel switches
2018-03-19T15:50:53 < hdt551> I get garbled audio (going to a sgtl5000).
2018-03-19T15:51:02 < Cracki> note _philips_ i2c
2018-03-19T15:51:11 < Cracki> I think I saw other flavors too
2018-03-19T15:51:32 < hdt551> Cracki: but it seems the diagram does not match what is shown on codec chips.
2018-03-19T15:51:43 < Cracki> look for modes
2018-03-19T15:51:54 < Cracki> seems you can use other transmission modes besides philips
2018-03-19T15:52:36 < hdt551> Cracki: I have certainly tried them all.

2018-03-19T15:52:40 < Cracki> hm
2018-03-19T15:53:12 < Cracki> these diagrams always specify cpol=0, does your chip maybe need something else?
2018-03-19T15:53:27 < Cracki> this _is_ based on SPI, so you have cpol, cpha to vary
2018-03-19T15:54:45 < hdt551> I can't say I have tried changing that.  I will give it a try.
2018-03-19T15:56:09 < Cracki> better figure out what the chip wants

2018-03-19T15:58:57 < hdt551> I can say when using ST's I2S protocol, sigrok is able to correctly decode it, except the left/right channels are reversed.
2018-03-19T16:13:37 < Cracki> what are you interfacing to
2018-03-19T16:13:45 < Cracki> I think you never mentioned that
2018-03-19T16:14:21 < Cracki> nvm, "sgtl5000"
2018-03-19T16:14:39 < Cracki> https://www.nxp.com/products/media-and-audio/audio-converters/audio-codec/ultra-low-power-audio-codec:SGTL5000?tab=Documentation_Tab
2018-03-19T16:15:40 < hdt551> Cracki: yes the sgtl5000.  I have looked at the datasheets for other codecs and they show similar I2S Philips diagrams (not matching ST's)
2018-03-19T16:16:07 < Cracki> https://www.nxp.com/docs/en/application-note/AN3664.pdf
2018-03-19T16:16:28 < Cracki> is that perhaps the issue, the duration of the frame clock "pulse"
2018-03-19T16:17:46 < hdt551> I haven't seem that document before.
2018-03-19T16:18:18 < Cracki> click the link before that, all their relevant docs
2018-03-19T16:19:41 < hdt551> Cracki: I will go through them.  I had only seen the errata about the VDDD pin before. Thank you.
2018-03-19T16:20:50 < Cracki> the standard figures in the main data sheet match though... they _also_ have that one bit of delay between lrclk and dout
2018-03-19T16:21:47 < Cracki> looks like when lrclk is sampled and seen to have changed, that's also the last bit of the current frame. the new frame starts at the next sclk
2018-03-19T16:22:22 < Cracki> maybe alignment issues, but unlikely if you work with 16bit 2ch data
2018-03-19T16:23:23 < Cracki> uh, weird... they have 3 figures, and only the first has this. the other ones (justified formats) don't
2018-03-19T16:23:55 < Cracki> what have they been smoking
2018-03-19T16:23:59 < hdt551> Cracki: I am using 16bit data.

2018-03-19T16:34:31 < hdt551> Cracki:Seems likely.  I can say I have tried all the formats (except maybe the "extended" ones ST has) and have gotten varying levels of distortion.
2018-03-19T16:34:59 < Cracki> do look at it with a scope or at least a logic analyzer
2018-03-19T16:35:00 < hdt551> Cracki: So ultimately I have to conclude I am doing something wrong.
2018-03-19T16:35:36 < Cracki> if cpol/cpha are wrong, it'd sample on edges. that certainly gets you flipped bits.
2018-03-19T16:35:53 < hdt551> I have checked test data with a logic analyser (sigrok) and it does decode the I2S Philips format.
2018-03-19T16:36:07 < Cracki> sigrok can be forgiving.

2018-03-19T16:53:36 < Cracki> check cpol/cpha settings and such
2018-03-19T16:54:22 < Cracki> send a constant value, 0xACAC or something like that

2018-03-19T19:16:07 < Adluc> what gprs module is on board and how much uF is on borad now?
2018-03-19T19:17:04 < Adluc> qyx: ^
2018-03-19T19:17:14 < qyx> there are two 470u and some 10uF ceramics
2018-03-19T19:17:19 < qyx> but generally this doesn't cause problems
2018-03-19T19:17:32 < qyx> except when there is super low signal
2018-03-19T19:17:53 < qyx> and the radio outputs full power
2018-03-19T19:18:44 < Ultrasauce> i bet the module itself has a pretty decent brownout tolerance, maybe the solution is as simple as a diode and decent cap on the mcu
2018-03-19T19:18:57 < Adluc> Ultrasauce: why diode?
2018-03-19T19:19:10 < Ultrasauce> so that the radio can't brownout the mcu
2018-03-19T19:19:11 < qyx> yes it has, it causes problems regularly
2018-03-19T19:19:29 < qyx> no, there are no power supply problems
2018-03-19T19:19:42 < qyx> just some emi causing i2c malfunction
2018-03-19T19:19:48 < qyx> because me dumb and using internal pullups
2018-03-19T19:20:28 < qyx> fixed it running at 10kHz
2018-03-19T19:21:05 < qyx> 300mV drop doesn't harm anything because thats on the 5V rail, the mcu is powered by a dedicated 2.8V step-down

2018-03-19T20:07:10 < kakimir> hello pumpphiles
2018-03-19T20:08:47 < upgrdman> is there a phrase to search for if i want to buy stuff to make one axis of a cnc/etc.? e.g. i want a pair of rails, their linear bearings, an acme or ball screw+nut + pillow blocks.
2018-03-19T20:09:53 < jpa-> "2 linear actuators"
2018-03-19T20:10:16 < jpa-> https://www.ebay.com/itm/Ball-Screw-Linear-CNC-Slide-Stroke-60mm-400mm-Long-Stage-Actuator-Stepper-Motor/292138883593?hash=item4404d59a09:m:m88C6-uYA-NNwR2sSb-_laQ   if a pair of something like this would work
2018-03-19T20:10:45 < upgrdman> well i only need one stepper
2018-03-19T20:10:48 < kakimir> wow my headphone jack is now better than before
2018-03-19T20:10:55 < kakimir> it actually sticks into my laptop
2018-03-19T20:10:57 < jpa-> "linear stage" also
2018-03-19T20:11:00 < upgrdman> rails would be spaced far apart, with acme/ball screw in the middle
2018-03-19T20:11:05 < kakimir> and needs conciderable force to pull out
2018-03-19T20:11:10 < upgrdman> hmm
2018-03-19T20:12:30 < jpa-> "linear rail kit"   also

2018-03-19T20:44:09 < blacktronics> you literally get to pick between shitty bushings that don't look like they have an adjustment screw, or a "linear rail" that consists of skateboard bearings pressed against an aluminium surface lol

2018-03-19T21:06:21 < qyx> if you remember my weird malfunctions after the metal case was closed
2018-03-19T21:07:39 < qyx> on the failing board
2018-03-19T21:07:43 < qyx> there is a programming connector
2018-03-19T21:08:16 < qyx> a standard 10pin cortex one
2018-03-19T21:08:21 < qyx> with a NRST pin on the edge
2018-03-19T21:08:37 < qyx> in the case, there is a conductive foam as a thermal insulation
2018-03-19T21:08:47 < qyx> the case is connected to the ground obviously
2018-03-19T21:09:02 < jpa-> change the pinout and you have a nice intrusion detector
2018-03-19T21:09:09 < qyx> when the case was closed, the cortex 10pin header touched the conductive foam on the back side of the enclosure
2018-03-19T21:09:34 < qyx> ant the board as kep in reset all the time
2018-03-19T21:09:39 < qyx> Laurenceb level fail.

2018-03-19T21:22:11 < englishman> hey BrainDamage i got a new reflex sight and it broke immediately
2018-03-19T21:22:55 < BrainDamage> let me guess, the glass mount was shit and the recoil force tilted it off axis
2018-03-19T21:23:36 < englishman> no the crappy battery cover has a single tiny thread and it popped off and i had to dig around on the ground for it
2018-03-19T21:24:00 < stvn> While the enemy was firing at you?
2018-03-19T21:24:10 < englishman> i dont have any enemies
2018-03-19T21:24:12 < BrainDamage> that's fixable if warranty doesn't cover you, just re-thread it with a larger screw
2018-03-19T21:24:25 < blacktronics> i think he meant it literally has one thread
2018-03-19T21:24:28 < blacktronics> as in length

2018-03-19T21:27:53 < Steffanx> BrainDamage yeah. I totally forgot about it. I wasnt going to bring some, but mr tct had some.
2018-03-19T21:28:15 < Steffanx> on my way back i suddenly realized it
2018-03-19T21:28:31 < englishman> we all know the real reason for your trip was the international waffel trade
2018-03-19T21:29:03 < Steffanx> Nope. I shipped them upfront
2018-03-19T21:29:58 < BrainDamage> btw, why not get fancy tritium light reflex sight? reflex doesn't need lazor
2018-03-19T21:30:05 < BrainDamage> so you can use tritium
2018-03-19T21:30:23 < englishman> they are kinda big no?
2018-03-19T21:30:25 < englishman> and expensive
2018-03-19T21:30:46 < Steffanx> actually it was just the punishment for being late 3 hours BrainDamage :P

Or -- if you're really serious -- you could use floating point gate arrays to design a new console that makes them look great on modern TVs."
2018-03-19T23:35:35 < upgrdman> floating point gate arrays, huh
2018-03-19T23:37:46 < zyp> fpgas, you know
2018-03-19T23:37:53 < upgrdman> yes
2018-03-19T23:38:02 < upgrdman> not field programmable, but floating point
2018-03-19T23:38:06 < upgrdman> because reasons
2018-03-19T23:38:50 < Thorn> why not fixed point gate arrays
2018-03-19T23:39:09 < Thorn> that would at least be somewhat accurate
2018-03-19T23:40:40 < sync> Thorn: because then you gotta wrap your head around the fixed point format

2018-03-20T00:10:07 < aandrew> few guys on irc actually make cycle-correct emulators with FPGAs

2018-03-20T00:14:41 < jadew> sync, is there anything stopping you from making a cal kit and measuring it against a known kit?
2018-03-20T00:14:45 < karlp> apparently some of the games that were deeply designed for the interlacing look "better" when you use these fpga intersposers
2018-03-20T00:14:54  * karlp doesn't take retrogaming nearly that seriously .)
2018-03-20T00:15:35 < sync> of course not jadew
2018-03-20T00:15:47 < sync> it is just not trivial to make a good performing cal kit
2018-03-20T00:16:25 < jadew> in what way? if the result is repeatable, isn't that enough?
2018-03-20T00:20:39 < sync> you still want a reasonably flat response phase and frequency wise

2018-03-20T00:42:15 < upgrdman> sync (or anyone else) ... im looking into buying some linear rails, bearings, and a acme/ball screw. it looks like there common names, e.g. "SBRU12" bearing blocks etc. what do i google to find a table of common shitz
2018-03-20T00:45:48 < sync> ballscrew iirc 1605 is common
2018-03-20T00:45:56 < sync> although you really want a screw with more lead
2018-03-20T00:46:13 < upgrdman> ?
2018-03-20T00:46:30 < upgrdman> hmm this looks like it might do  https://www.ebay.com/itm/SBR20-600mm-2-linear-rail-ballscrew-RM1605-600mm-1-set-BK-BF12-end-bearing-CNC/182816367159?hash=item2a90b46237:g:9LYAAOSwo6lWJzYF
2018-03-20T00:47:01 < sync> what do you want to use it for?
2018-03-20T00:47:59 < upgrdman> need to prototype what is basically a giant flatbed scanner
2018-03-20T00:48:10 < sync> does it need to scan fast at all?
2018-03-20T00:48:30 < upgrdman> no. ~2 seconds
2018-03-20T00:48:35 < upgrdman> maybe 5 is fine
2018-03-20T00:48:40 < sync> for which distance?
2018-03-20T00:48:52 < upgrdman> 600mm (well ~500 usable)
2018-03-20T00:49:24 < sync> so about 7.2m/min
2018-03-20T00:49:30 < sync> that is reasonably quick
2018-03-20T00:49:33 < sync> go for a higher lead screw
2018-03-20T00:49:54 < upgrdman> ok
2018-03-20T00:50:02 < sync> so 1610 or even 1620
2018-03-20T00:50:12 < upgrdman> what do those numbers mean :)
2018-03-20T00:50:18 < sync> diameter and lead
2018-03-20T00:50:41 < upgrdman> so 1610 is 16mm diameter, 10mm per revolution?
2018-03-20T00:50:45 < sync> yes
2018-03-20T00:50:48 < upgrdman> k
2018-03-20T00:51:10 < upgrdman> RM1605, whats rm
2018-03-20T00:51:33 < upgrdman> hmm actually
2018-03-20T00:51:37 < upgrdman> i dont even need ball screw
2018-03-20T00:51:47 < upgrdman> i dont need much precision. maybe belt
2018-03-20T00:52:35 < upgrdman> is there a name for like a belt kit? like pully + belt + tensioner + the nick to mount to the gantry
2018-03-20T00:52:44 < upgrdman> s/nick/thing
2018-03-20T00:53:08 < sync> not sure if the chinacloners have something in stock
2018-03-20T00:53:18 < sync> but belt driven linear units are a thing
2018-03-20T00:53:56 < upgrdman> ya i see whole stages
2018-03-20T00:54:01 < upgrdman> but theyre more expensive
2018-03-20T00:54:17 < upgrdman> i can get rails + pillowblocks for $40-60
2018-03-20T00:54:20 < sync> yes
2018-03-20T00:54:24 < sync> but your time also costs moni
2018-03-20T00:54:28 < upgrdman> hoping to find belt stuff for <$40
2018-03-20T00:54:47 < upgrdman> ya but this prototype may become a product. it should if i dont fuck up too bad
2018-03-20T00:55:06 < upgrdman> and it'll be made in china, where human labor is ~free

2018-03-20T00:57:06 < upgrdman> but there no part to mount to the gantry :/
2018-03-20T00:58:42 < upgrdman> is there a name for that part? ebay isnt cooperating
2018-03-20T00:59:52 < fest> which part?
2018-03-20T01:00:13 < upgrdman> the part that connects a belt to the moving part (gantry)
2018-03-20T01:01:44 < fest> timing belt clip?
2018-03-20T01:03:47 < upgrdman> hmm
2018-03-20T01:04:23 < upgrdman> so im finding belts/pullys/etc on ebay when i search for "printer belt kit" but whats the right phrase to use
2018-03-20T01:04:40 < upgrdman> like belt for motion control or someshit
2018-03-20T01:04:53 < upgrdman> timing belt results in lots of random shit
2018-03-20T01:05:01 < fest> T2.5/T5 timing belt
2018-03-20T01:05:38 < fest> i.e. specify the pitch you're after
2018-03-20T01:06:22 < upgrdman> t5 == 5mm teeth pitch?
2018-03-20T01:06:26 < Cracki> aye
2018-03-20T01:06:33 < Cracki> "GT2" belt and pulleys can be cheap off aliexpress. it's used in lots of 3d printers.
2018-03-20T01:06:46 < Cracki> (ultimaker series, for one)
2018-03-20T01:07:15 < Cracki> GT is a special tooth shape that has no slip. normal T-type teeth *might* allow for some slip
2018-03-20T01:07:19 < upgrdman> gt2 is 5mm pitch?
2018-03-20T01:07:25 < Cracki> gt2 is 2mm pitch
2018-03-20T01:07:31 < upgrdman> ya i was gonna say
2018-03-20T01:07:39 < Cracki> what are you gonna pull with the belt?
2018-03-20T01:07:40 < upgrdman> 2mm would prolly be too weak for my app
2018-03-20T01:07:44 < Cracki> gt2 is commonly 6-9mm wide
2018-03-20T01:07:50 < upgrdman> 2-5kg
2018-03-20T01:07:51 < Cracki> gt2.5/3/5 can be a lot wider
2018-03-20T01:08:13 < Cracki> 5mm pitch is something you might find in your car engine :P
2018-03-20T01:08:23 < upgrdman> ok maybe gt3 then :)
2018-03-20T01:08:52 < Cracki> go look for pulleys too. inner bore is important for whatever motor you want to put it on.
2018-03-20T01:09:00 < Cracki> nema17 steppers have 5mm axles
2018-03-20T01:09:43 < blacktronics> fake GT2 suck
2018-03-20T01:10:09 < blacktronics> they are like  chinese ballscrews
2018-03-20T01:10:09 < Cracki> it's all just rubber, what's gonna happen eh
2018-03-20T01:10:25 < Cracki> ballscrews are like thumbscrews
2018-03-20T01:10:41 < blacktronics> chinese ballscrews suck
2018-03-20T01:10:56 < blacktronics> better go with equally priced brand trapezoidal screws and they are better
2018-03-20T01:11:07 < blacktronics> all the chinese crap is not very linear and horrible
2018-03-20T01:11:15 < upgrdman> if only there was like a retail store that stocked this shit :/
2018-03-20T01:11:30 < upgrdman> (more than just maker-level stuff)
2018-03-20T01:11:30 < blacktronics> i also recommend using (genuine gates) GT3 2MGT instead of GT2
2018-03-20T01:11:38 < blacktronics> they have better torque transmission
2018-03-20T01:12:50 < upgrdman> is there a catalog where i can get a quick gist of all this shit. like rail types, belt types, pullies, etc.
2018-03-20T01:13:02 < Cracki> reprap wiki :>
2018-03-20T01:13:12 < upgrdman> none of my coworkers know shit about mechanical :(

2018-03-20T01:13:52 < Cracki> what's the MGT number for?
2018-03-20T01:14:06 < blacktronics> 2MGT is 2mm pitch GT profile
2018-03-20T01:14:18 < blacktronics> GT3 is the actual tooth profile name
2018-03-20T01:14:19 < Cracki> ah 2 mm GT
2018-03-20T01:14:27 < Cracki> so what's GT3 8MGT?
2018-03-20T01:14:31 < blacktronics> not sure why they put the GT on there
2018-03-20T01:14:33 < fest> upgrdman: I like Dunlop BTL catalogue for stuff like that
2018-03-20T01:14:36 < blacktronics> 8mm pitch
2018-03-20T01:14:50 < Cracki> huh, must look toothless
2018-03-20T01:15:15 < blacktronics> 8mm is bigger
2018-03-20T01:15:20 < fest> find local dealers, call them and ask for catalogue
2018-03-20T01:15:24 < Cracki> ah nvm, GT3 is just the shape, not including pitch?
2018-03-20T01:15:58 < blacktronics> yes
2018-03-20T01:16:03 < blacktronics> GT2 is also just shape
2018-03-20T01:16:19 < Cracki> *peruses catalog*
2018-03-20T01:16:36 < blacktronics> but the chinese fucked up the internet so all you can find is fake GT2 and people think the 2 means 2mm pitch
2018-03-20T01:16:48 < karlp> hate it when that happens :|
2018-03-20T01:17:21 < Cracki> good to know

2018-03-20T01:18:43 < blacktronics> this is a nice source for belts
2018-03-20T01:19:21 < Cracki> and bearings
2018-03-20T01:19:24 < blacktronics> they have rolls of closed belts and can even cut you a desired width
2018-03-20T01:19:43 < blacktronics> like, you can order a 70cm wide belt
2018-03-20T01:21:29 < blacktronics> also look at https://www.igus.com/
2018-03-20T01:21:55 < blacktronics> i used some of their plastic TR16x4 leadscrew nuts before, they work exceptionally well
2018-03-20T01:21:59 < blacktronics> better than the brass ones

2018-03-20T02:08:19 < Cracki> just order a linear guide and pull it with belt. lots faster than screwing around
2018-03-20T02:08:48 < Cracki> unless you're making a cnc :P
2018-03-20T02:22:22 < blacktronics> depends
2018-03-20T02:22:45 < blacktronics> igus makes some multi-start high pitch leadscrews
2018-03-20T02:24:16 < blacktronics> https://www.igus.com/wpck/17149/dryspin_High_helix_leadscrews
2018-03-20T02:25:44 < blacktronics> keep in mind that when using servos or steppers your resolution changes with your transmission ratio
2018-03-20T02:26:24 < blacktronics> its why 3d printers use such tiny pulleys- much larger and the 1.8° steppers would move the nozzle too much in a single step
2018-03-20T02:27:02 < blacktronics> so you have to figure out what you need in speed, resolution and torque and then make a choice

2018-03-20T04:23:19 < englishman> Munilla Construction Management (MCM), the South Miami-based firm that designed the FIU foot bridge, has been sued multiple times for unsafe practices in the past.
2018-03-20T04:23:19 < englishman> In early March MCM was sued by a construction worker who was severely injured when MCM’s “makeshift bridge” at Miami’s International Airport collapsed.

2018-03-20T10:18:03 < c10ud> is sftp doable with mcus?
2018-03-20T10:18:11 < dongs> is that some lunix trash

2018-03-20T10:19:11 < c10ud> ah, I have a board with wiznet and I've been asked for sftp stuff, I was wondering if it was easier to use a rageberry or do everything within my mcu
2018-03-20T10:19:18 < dongs> wiznet lol
2018-03-20T10:19:19 < dongs> the fuck
2018-03-20T10:19:24 < dongs> i thought that was retarduino domain
2018-03-20T10:19:28 < dongs> isnt that the SPI ethernet shit?
2018-03-20T10:19:47 < c10ud> yea
2018-03-20T10:19:54 < c10ud> don't ask, not my choice :\

2018-03-20T10:19:58 < dongs> i guess it will work
2018-03-20T10:20:03 < dongs> i've seen wolfssl shit used somewehre
2018-03-20T10:20:19 < c10ud> yeah I was just looking at that
2018-03-20T10:22:06 < BrainDamage> sftp is NOT ssl ftp
2018-03-20T10:22:12 < BrainDamage> ssl ftp is ftps
2018-03-20T10:24:47 < dongs> fucked if I know
2018-03-20T10:24:49 < dongs> i dont lunix
2018-03-20T10:25:23 < BrainDamage> your link is right
2018-03-20T10:25:34 < BrainDamage> it's him mixing up sftp with ftps
2018-03-20T10:25:41 < qyx> we used wolfssl
2018-03-20T10:25:47 < qyx> the code was shit at that time
2018-03-20T10:25:53 < qyx> but worked
2018-03-20T10:26:54 < qyx> also that wiznet has tcp/ip offload, probably even ssl
2018-03-20T10:27:05 < qyx> or was it that st wifi module

2018-03-20T10:41:09 < c10ud> so, it looks like I could just need to wrap my wiznet socket into wolfssl and put some ftp commands inside it

2018-03-20T13:10:54 < dongs> okies thanks <3 thorn
2018-03-20T13:12:42 < karlp> they're normally tired together
2018-03-20T13:12:52 < karlp> separate is for tricky collision detection stuff

2018-03-20T13:14:19 < stvn> jewtooth was a new entry for today
2018-03-20T13:14:25 < dongs> wat
2018-03-20T13:14:33 < dongs> ive used that for literally years
2018-03-20T13:14:50 < stvn> maybe i haven't been here long
2018-03-20T13:15:41 < stvn> oh modbus, i see
2018-03-20T13:16:03 < dongs> and modbugs isn't my name for it
2018-03-20T13:17:00 < stvn> hmmm
2018-03-20T13:20:12 < karlp> anyone used LIN at all?
2018-03-20T13:20:19 < dongs> i've heard those words
2018-03-20T13:20:41 < dongs> so you need to set device address on each modbus node?
2018-03-20T13:20:58 < karlp> dongs: unfortuantely, yes.
2018-03-20T13:21:23 < karlp> you can probably do soem clever tricks with broadcasts to assign addrsses, but I've nto done it yet
2018-03-20T13:21:53 < karlp> I just use the uniqueid to make up a modbus address and "check your serials before you put them all together"
2018-03-20T13:21:57 < dongs> like repeatedly pinging broadcast in a network of empty nodes and have each one grab an address in sequence?
2018-03-20T13:21:58 < qyx> yes but only with some babylin shit
2018-03-20T13:22:27 < karlp> dongs: something like that, but the algorithm of how to have them pick the addresses I've not worked out or seen yet :)
2018-03-20T13:22:34 < dongs> right
2018-03-20T13:22:47 < karlp> everything I've seen in use has just had a UI or knobs
2018-03-20T13:23:02 < karlp> and often just a default address, and you can then change it via modbus :)
2018-03-20T13:23:33 < karlp> I keep thinking it would be neat to do the autoaddressing algorithm, but it keeps not actually being a real operational problem.
2018-03-20T13:23:35 < dongs> so like connect something point to point then set address and connect into the rest of the shit right
2018-03-20T13:23:47 < karlp> yeah, that's done too.
2018-03-20T13:23:52 < Thorn> (1) set default address (like 1) on all new devices (2) connect devices to the bus one by one (3) make the master issue a 'change address' command to address 1
2018-03-20T13:24:07 < dongs> that woudl make sense
2018-03-20T13:24:46 < Thorn> it is a lot of hassle for the installers but that's about the only way (other than DIP switches or real UI with a display) that seems to work in practice afaict
2018-03-20T13:25:43 < Thorn> (and the electricians don't get binary so you have to provide them with pictures of what the dip switch should look like for every address lol)
2018-03-20T13:25:56 < dongs> lol
2018-03-20T13:26:20 < dongs> just add more dipswitches and use BCD
2018-03-20T13:27:05 < dongs> or how NTT used to do wired phones, they had those spinny 0..7 knobs x 3
2018-03-20T13:27:08 < dongs> to set device address
2018-03-20T13:27:49 < dongs> is rageberry 3+ still HDMI 1.4? lol
2018-03-20T13:27:58 < dongs> how can broadcom keep pumping so much shit
2018-03-20T13:28:05 < dongs> when there's so much better SoC shit out there in 2018
2018-03-20T13:29:20 < zyp> I have some shit on my desk here with two spinny 0-15-knobs, to set an 8-bit address
2018-03-20T13:29:41 < dongs> so to set each hex quadlet or whatever?
2018-03-20T13:29:47 < zyp> yes
2018-03-20T13:30:03 < dongs> must be an expensive knob
2018-03-20T13:30:12 < qyx> you should use a 10K trimpot
2018-03-20T13:30:24 < qyx> adc it and yolo
2018-03-20T13:30:24 < dongs>  but its not clicky

2018-03-20T13:32:34 < dongs> that feel when you google XR77004 and the first thing that comes up is a shitberry "schematic"
2018-03-20T13:33:42 < zyp> for the shit I'm making to talk to this, address will be set by some shit hooked up to an out of band config port or something
2018-03-20T13:34:08 < stvn> i like the pic
2018-03-20T13:35:15 < dongs> me too
2018-03-20T13:35:23 < dongs> it looks surprisingly well taken
2018-03-20T13:35:29 < dongs> and not a filthy cellphone shot
2018-03-20T13:35:46 < zyp> what? the one I just posted?
2018-03-20T13:35:53 < qyx> I don't because ~orange
2018-03-20T13:35:56 < zyp> it's totally a filthy cellphone shot
2018-03-20T13:36:01 < dongs> orange is awesaome
2018-03-20T13:36:21 < qyx> fuk parrot-colored industry shit
2018-03-20T13:36:41 < qyx> I am just being grumpy
2018-03-20T13:37:34 < karlp> single connectiona nd reconfigure each one as you go is a pain in the arse, I wouldn't want to be on the endo fo the support calls from that :)
2018-03-20T13:37:44 < dongs> then what?
2018-03-20T13:37:50 < zyp> the scheme Thorn suggested is how USB works
2018-03-20T13:38:02 < karlp> usb is point to point, it's not relevant.
2018-03-20T13:38:19 < karlp> fixed addresses per device so yo uhave a _chance_ of not having to configure things
2018-03-20T13:38:24 < karlp> then configure things if you need to.
2018-03-20T13:38:46 < karlp> but if you need to install 15-20 devices, and they all are just "modbus address 1" and yo uhave to connect them one by one and reconfigure them, you're in for installer hatred.
2018-03-20T13:39:00 < zyp> all USB devices have address 0 after reset, host enables one by one port, so that there's only one addr 0 device on the bus at a time
2018-03-20T13:39:05 < Thorn> usb is semi-broadcast
2018-03-20T13:39:10 < karlp> but that's their life, so it's ok.
2018-03-20T13:39:10 < jpa-> https://www.digikey.com/product-detail/en/omron-electronics-inc-emc-div/A7BS-254-1/A7BS-254-1-ND/368277   rich people would use these
2018-03-20T13:39:31 < karlp> wow, those are pricy :)
2018-03-20T13:39:36 < dongs> haha wow
2018-03-20T13:39:39 < dongs> im sure china has clones for less
2018-03-20T13:39:43 < dongs> i've seen them in a tons of chinese shit
2018-03-20T13:39:51 < karlp> I think the thumbwheels are cheaper, but they're space that's might not be available
2018-03-20T13:40:24 < zyp> I worked out an address assignment scheme for CAN once
2018-03-20T13:40:39 < dongs> can is useless because of message size
2018-03-20T13:41:20 < jpa-> nowadays one could also put an NFC chip into the device so you can program it with smartphone
2018-03-20T13:41:30 < zyp> do a broadcast "get info" request on the bus, get back a packet from each device containing serial
2018-03-20T13:41:54 < zyp> then do a broadcast "set this address if you have this serial" command
2018-03-20T13:42:44 < qyx> how would you do the get info
2018-03-20T13:42:52 < zyp> that should work for administratively assigning addresses on any bus that doesn't rely on a master sequencing who can talk when
2018-03-20T13:42:53 < qyx> when all devices are initially set to the same address
2018-03-20T13:43:06 < zyp> like I said, broadcast
2018-03-20T13:43:06 < qyx> *same id
2018-03-20T13:43:08 < karlp> this shit isn't all that uncommon: https://www.sabur.com.pl/nasza-oferta/systemy-zarzadzania-energia/pcd7-h104d/
2018-03-20T13:43:23 < qyx> yes, but can is source addressed
2018-03-20T13:43:30 < zyp> no, it's not
2018-03-20T13:43:32 < karlp> zyp: how do you do the "get info" ?
2018-03-20T13:43:35 < qyx> if there are two slaves responding with the same id
2018-03-20T13:43:36 < karlp> they can't reply
2018-03-20T13:43:39 < qyx> there will be a conflict
2018-03-20T13:43:45 < zyp> no, there will not be
2018-03-20T13:43:51 < qyx> how so
2018-03-20T13:43:52 < karlp> we're not talking about can.
2018-03-20T13:43:59 < karlp> or at least, we weren't.
2018-03-20T13:44:04 < qyx> 12:40 < zyp> I worked out an address assignment scheme for CAN once
2018-03-20T13:44:08 < qyx> I though we are :)
2018-03-20T13:44:09 < jpa-> camera sensors are also pretty cheap, just provide a window where you can write the address with a marker and do some computer vision to read it out :)
2018-03-20T13:44:13 < karlp> well, who cares about can, that has no conflicts.
2018-03-20T13:44:44 < qyx> but again, master sends a get_info commands, that si ok
2018-03-20T13:44:55 < qyx> every slave listens for that command (filter set for a particular id)
2018-03-20T13:45:00 < qyx> but then every slave has to respond
2018-03-20T13:45:04 < zyp> yes
2018-03-20T13:45:06 < qyx> but if they respond at the same time
2018-03-20T13:45:08 < qyx> with the same id
2018-03-20T13:45:13 < zyp> the bus needs to handle anticollision
2018-03-20T13:45:18 < jpa-> can detects collisions on first bit that differs
2018-03-20T13:45:20 < qyx> can handles it
2018-03-20T13:45:20 < zyp> CAN does that, ethernet does that
2018-03-20T13:45:39 < jpa-> doesn't have to be address bit IIRC
2018-03-20T13:45:44 < qyx> aha so it will yield when the first bit of the address differs
2018-03-20T13:45:48 < zyp> jpa-, correct
2018-03-20T13:45:52 < qyx> I mean the serial

2018-03-20T13:45:56 < qyx> I understand now
2018-03-20T13:45:57 < zyp> qyx, yes
2018-03-20T13:46:26 < zyp> CAN arbitration will abort and retry as soon as it detects a collision, no matter how far out in the message
2018-03-20T13:46:53 < qyx> but the number of retransmissions will need to be set fairly high
2018-03-20T13:47:41 < zyp> no, I think retransmissions refer to messages that aren't ACKed, not collisions
2018-03-20T13:48:27 < zyp> anyway
2018-03-20T13:48:53 < karlp> so dongs, what are you going to do?
2018-03-20T13:49:02 < zyp> I think 1-wire uses sort of a similar scheme
2018-03-20T13:49:09 < dongs> karlp: not sure, just kikemir'ing at the moment
2018-03-20T13:49:15 < zyp> IIRC they use full 48-bit unique addrs or something
2018-03-20T13:49:24 < dongs> most likely set default address and have niggers walk around with a thing that sets them
2018-03-20T13:49:32 < zyp> and to detect devices on the bus, they use a binary search
2018-03-20T13:49:34 < karlp> yeah, that have unique ids, and they do a divide in 2 address repeating thing to sort them out
2018-03-20T13:49:36 < karlp> yeah
2018-03-20T13:49:48 < karlp> but that relies on everyone having a big unique id,
2018-03-20T13:49:54 < zyp> I think a sort of a binary search could work on RS485
2018-03-20T13:50:00 < karlp> can't rely on that with modbus, you need a way of telling people to move to another address
2018-03-20T13:50:03 < zyp> yes, so does my serial scheme
2018-03-20T13:50:15 < qyx> I am using the same with my multidrop spi
2018-03-20T13:50:21 < karlp> well, it all needs device support to work anyway :)
2018-03-20T13:50:34 < qyx> randomly set addresses
2018-03-20T13:50:37 < karlp> and hasn't proven to be a real hard requirement anyway
2018-03-20T13:51:24 < karlp> "random" ids from the hash of the uniqueid printed on the label, last byte is the modbus address, and "check your system you don't have dupes => pick another from the box, they're all interchangeable"
2018-03-20T13:52:17 < dongs> heh
2018-03-20T13:52:20 < zyp> for my ethernet workstuff, I have model/revision/serial stored in OTP for every device, and then I use that to derive MAC addrs
2018-03-20T13:52:59 < zyp> my bootloader is just using MAC broadcast and MAC addrs to find and address devices
2018-03-20T13:53:14 < dongs> don't you need a registered OUI or whatev for mac stuff?
2018-03-20T13:53:33 < qyx> you are kidding
2018-03-20T13:53:35 < dongs> and then the last 3 bytes can just come from unique ID
2018-03-20T13:53:45 < zyp> dongs, depends
2018-03-20T13:54:25 < zyp> you need an OUI to guarantee globally unique mac address
2018-03-20T13:55:10 < jpa-> there is even the official "local" MAC address area that has enough space that collision is very unlikely
2018-03-20T13:55:39 < zyp> but this stuff is only ever going to run in dedicated L2 segments, i.e. with only devices we've made or devices we're specifically supporting
2018-03-20T13:56:23 < qyx> even when selecting macs randomly from the "locally administered space" there is super low chance of a collision
2018-03-20T13:56:24 < zyp> and half the OUI namespace is reserved for private addressing
2018-03-20T13:57:45 < zyp> the private part is then subdivided into several regions (ref SLAP), one of which is AAI
2018-03-20T13:58:10 < zyp> all x2:xx:xx prefixes are AAI unicast
2018-03-20T13:58:33 < zyp> so currently I've just picked 02:00:00 as my OUI
2018-03-20T13:58:57 < zyp> and the last 24 bits are derived from OTP data
2018-03-20T13:59:42 < Thorn> why couldn't the USB Consortium do the same and allocate VIDs for private use
2018-03-20T13:59:44 < zyp> https://bin.jvnv.net/file/IZ5Sa.png <- when my bootloader util detects devices, it looks like this
2018-03-20T13:59:44 < jpa-> why not 5a:79:70?
2018-03-20T14:00:01 < jpa-> Thorn: because they want money
2018-03-20T14:00:17 < zyp> jpa-, xa:xx:xx is reserved for CIDs
2018-03-20T14:00:31 < zyp> CIDs are assigned like OUIs
2018-03-20T14:01:18 < jpa-> ah, too bad
2018-03-20T14:01:19 < zyp> but yes, this stuff can work with any prefix now

2018-03-20T14:01:43 < zyp> currently I have 02:00:00 hardcoded in firmware, but I can change that at any time through a firmware upgrade
2018-03-20T14:01:57 < jpa-> i thought anything with 0x02 bit set was local
2018-03-20T14:01:59 < zyp> e.g. if we end up buying an OUI at some point
2018-03-20T14:02:19 < zyp> it is, but SLAP subdivides that into four quadrants
2018-03-20T14:02:31 < jpa-> yeah, google is telling me that now :)
2018-03-20T14:04:13 < zyp> AAI (assigned by local admin), CID (assigned by IEEE RA), SAI (assigned automatically, by protocol) and one reserved section
2018-03-20T14:04:36 < zyp> the SAI section looks interesting, but there doesn't seem to be any useful defined protocols yet

2018-03-20T16:08:27 < Laurenceb> to simulate "crowdsourcing" of vibration data
2018-03-20T16:08:29 < Laurenceb> dont ask
2018-03-20T16:08:34 < Laurenceb> this project is full retard
2018-03-20T16:08:35 < PaulFertser> Stuck as in fully secured?
2018-03-20T16:08:38 < Laurenceb> no
2018-03-20T16:08:55 < Laurenceb> dropped there with no straps or anything
2018-03-20T16:09:08 < Laurenceb>  "simulating" phone on a car dashboard
2018-03-20T16:09:37 < PaulFertser> How many times was it tested, are the results consistent?
2018-03-20T16:09:40 < Laurenceb> good news for their failproject is its within ~1dB error below 40hz, which is what they are interested in
2018-03-20T16:09:52 < Laurenceb> PaulFertser: nobody knows....

2018-03-20T16:10:11 < Laurenceb> some perman00b is doing random shit right now
2018-03-20T16:10:25 < Laurenceb> I'm scraping the fileserver for data....

2018-03-20T16:11:08 < Laurenceb> <PaulFertser> it may well be, the data quality is shit tier
2018-03-20T16:11:35 < PaulFertser> That makes no sense, you can't say it's good below 40Hz then as well.
2018-03-20T16:11:45 < Laurenceb> one big problem is they are pulling close to 1g with the shaker, so phone keeps skidding about on the platform
2018-03-20T16:11:53 < Laurenceb> I guess yeah
2018-03-20T16:12:48 < Laurenceb> which 100meg csv file to download.....

2018-03-20T16:13:06 < PaulFertser> Also, it looks like it was done in 10Hz steps, that's just silly too, obviously one should get more fine details to be able to conclude anything, and as a sort of sanity checking.
2018-03-20T16:13:07 < Laurenceb> >no notes explaining the setup for each one

2018-03-20T18:43:10 < aandrew> right
2018-03-20T18:43:17 < aandrew> that's why I'm pushing 2x on the volts
2018-03-20T18:43:50 < Laurenceb> just use an eestor capacitor
2018-03-20T18:44:00 < aandrew> oh I finally figured out why altium reorders a components parts when I annotate... gotta lock down the individula parts in the component
2018-03-20T18:44:15 < aandrew> for a quad op amp it doesn't matter because all the parts are the same, but for an FPGA it's quite different. :-)

2018-03-20T19:16:46 < englishman> just dont buy anything that doesnt have more than 500k in stock at digikey
2018-03-20T19:16:54 < englishman> like, 50V 0402 10u caps

2018-03-20T19:17:05 < Laurenceb> nobody knows
2018-03-20T19:17:18 < Laurenceb> but its 100-1e-9% sure ot be a scam
2018-03-20T19:18:40 < BrainDamage> as always, until there's a widely reproducible proof, just ignore and pretend it's a scammer
2018-03-20T19:22:15 < Lux> right, sounds too good to be true
2018-03-20T19:22:47 < Lux> though i'd expect something like supercaps to be the next step in the electrical storage game
2018-03-20T19:24:05 < BrainDamage> supercaps have high power density, not energy density
2018-03-20T19:24:26 < BrainDamage> in terms of energy density they are still worse than batteries, but unlike batts they can deliver that energy really fast
2018-03-20T19:26:12 < Laurenceb> last time I looked supercap and lipo were pretty close in power density
2018-03-20T19:27:42 < BrainDamage> unrelated: https://slashdot.org/story/18/03/20/1643252/child-abuse-imagery-found-within-bitcoins-blockchain
2018-03-20T19:27:52 < ffffffffffffffff> I've seen some battlebots use supercaps, since they need to be heavy and only get ~3 minutes of action

2018-03-20T20:03:07 < Laurenceb> anyone here used qt?
2018-03-20T20:03:16 < Laurenceb> I need to sort a QList of ints
2018-03-20T20:03:45 < Laurenceb> so go from disordered ints to incrementing values
2018-03-20T20:04:02 < Laurenceb> then output a list of indices matching old order to new
2018-03-20T20:04:09 < Laurenceb> if there a function for this?
2018-03-20T20:04:11 < Laurenceb> *is
2018-03-20T20:04:55 < Laurenceb> inb4 system("matlab_function.m")
2018-03-20T20:11:13 < emeryth> put the values into a qmap, it will sort itself

2018-03-20T21:15:34 < Laurenceb> yup
2018-03-20T21:15:47 < stvn> What happen
2018-03-20T21:15:48 < blacktronics> probably because the grll is mad she can't use the shaker after work now
2018-03-20T21:15:51 < Laurenceb> kek
2018-03-20T21:16:02 < Steffanx> something like this blacktronics https://www.ebay.co.uk/itm/Gearing-Watson-Shaker-Data-Physics-SignalForce-Electrodynamic-Shakers/230818768794?hash=item35bddee79a:g:ZvMAAOxyakdRFApr
2018-03-20T21:16:05 < Laurenceb> blacktronics: its about the size of a microwave oven
2018-03-20T21:16:10 < Laurenceb> ^that
2018-03-20T21:16:27 < blacktronics> ohh one of those
2018-03-20T21:16:32 < blacktronics> i had something bigger in mind lol
2018-03-20T21:16:43 < Steffanx> déjà vu.
2018-03-20T21:17:02 < blacktronics> i was thinking of a big shaker plate

2018-03-20T21:17:48 < blacktronics> slighly smaller tho
2018-03-20T21:18:28 < Steffanx> Now i know its such tiny device it makes the breaking part much less interesting
2018-03-20T21:18:45 < blacktronics> yeah fuck
2018-03-20T21:18:51 < blacktronics> R U I N E D
2018-03-20T21:19:12 < blacktronics> @Laurenceb build your own shaker and put it on your desk
2018-03-20T21:19:19 < Laurenceb> ikr
2018-03-20T21:19:27 < blacktronics> if ur b& from the lab just make the desk your new lab
2018-03-20T21:19:29 < Laurenceb> I might buy a voice coil actuator off ebay
2018-03-20T21:19:44 < Laurenceb> voice coil actuator + cheap shit bass driver amp
2018-03-20T21:19:46 < blacktronics> what are you even shaking?
2018-03-20T21:19:53 < Laurenceb> sensors
2018-03-20T21:19:56 < blacktronics> buy a CRUNCH subwoofer
2018-03-20T21:19:58 < Laurenceb>  <50grams total
2018-03-20T21:20:01 < Laurenceb> or that yeah
2018-03-20T21:20:19 < Laurenceb> only need 5-400hz
2018-03-20T21:20:23 < blacktronics> tbh would be funny
2018-03-20T21:20:32 < blacktronics> use a subwoofer so its extra annoying
2018-03-20T21:20:53 < Laurenceb> I'm very tempted for trolling purposes
2018-03-20T21:20:57 < blacktronics> drive colleagues nuts with frequency sweeps
2018-03-20T21:21:31 < blacktronics> ohh you could also buy one of those shitty 12V air compressors and hack it
2018-03-20T21:21:37 < BrainDamage> play 10Hz tone in adjacent office during tests
2018-03-20T21:21:41 < blacktronics> they make the most annoying sound possible
2018-03-20T21:21:49 < BrainDamage> nah, you don't want it audible
2018-03-20T21:22:01 < BrainDamage> make it in the sub-hearing region, just enough to fuck with the measurements
2018-03-20T21:22:06 < blacktronics> put a rotary subwoofer in the closet
2018-03-20T21:22:17 < sync> s/subwoofer/engine/

2018-03-20T22:52:18 < upgrdman> anyone track how long their shoes last? i know thats a weird question, but ya. the pair i bought 2 months ago are nearly worn out, and they have only ~500 miles (800km) of use so far.
2018-03-20T22:52:54 < upgrdman> i seem to recall most of my shoes lasting 800-1000 miles
2018-03-20T22:58:33 < Ultrasauce> i wore my last pair >10000km for sure
2018-03-20T22:58:34 < stvn> Lol ok
2018-03-20T22:59:02 < Ultrasauce> they were basically falling apart at that point though, not remotely presentable
2018-03-20T22:59:33 < upgrdman> 10,000 km? lol srsly?
2018-03-20T23:00:24 < upgrdman> i wear mine until the soles are no longer water tight, and i think max i get was 1200 miles
2018-03-20T23:00:42 < stvn> Shoe rating
2018-03-20T23:00:52 < stvn> New on stm32
2018-03-20T23:00:59 < BrainDamage> they last me 1-2 years, according to this pedometer i do 30-50km/week
2018-03-20T23:01:39 < BrainDamage> which is about 1000-1500 mile per year
2018-03-20T23:02:09 < BrainDamage> and yes if the soles are not watertight i replace them immediately

2018-03-20T23:04:25 < BrainDamage> are you training for a marathon to be doing 100km/week?
2018-03-20T23:05:28 < stvn> Where do you walk 50km a week
2018-03-20T23:05:42 < Steffanx> 500 miles by car. ;)
2018-03-20T23:05:54 < upgrdman> me?
2018-03-20T23:06:12 < Steffanx> Ya
2018-03-20T23:06:35 < upgrdman> im walking 8 miles a day (plus whatever normal walking i do at work/home)
2018-03-20T23:07:10 < BrainDamage> to reach the train station i walk almost 2km daily, and 2 more to get back
2018-03-20T23:07:21 < stvn> Ah I see
2018-03-20T23:08:41 < upgrdman> i started around 3 years ago. 1.5 miles/day was painful. now 8 miles/day is fine, and 12 is painful
2018-03-20T23:09:17 < stvn> Why are you walking 8 miles?

2018-03-20T23:09:56 < stvn> Yah
2018-03-20T23:10:40 < BrainDamage> walking that much won't compensate 3 extra large hambugers per day with a giant portion of fries and 2L of cola
2018-03-20T23:11:16 < stvn> How about 1 hamburger
2018-03-20T23:11:36 < stvn> No fry

2018-03-21T01:38:39 < BrainDamage> i am a decent cook
2018-03-21T01:38:49 < englishman> isnt basic italian food just stale bread and oil
2018-03-21T01:39:00 < BrainDamage> bear in mind my idea of italian food has fuck to do with what american think of italian food
2018-03-21T01:39:15 < upgrdman> BrainDamage, can you recommend a receipe for beef bolognese + tagleatelle (prolly misspelled the fuck out of those words)
2018-03-21T01:39:43 < upgrdman> yes i want authentic, not fucking Olive Garden(tm) trash
2018-03-21T01:41:08 < BrainDamage> if you want the authentic it won't be beef alone, it's not sufficiently fat
2018-03-21T01:41:19 < BrainDamage> it's often combined with sausage or pork belly fat
2018-03-21T01:41:27 < upgrdman> hmm ok.
2018-03-21T01:42:54 < BrainDamage> do you know what's a mirepoix?
2018-03-21T01:43:46 < upgrdman> never heard that word
2018-03-21T01:44:06 < BrainDamage> it's a combination of vegetables that gets sauteed and it's the basis of many sauces
2018-03-21T01:44:13 < upgrdman> TIL
2018-03-21T01:44:17 < BrainDamage> it's also the basis of a proper ragu alla bolognese
2018-03-21T01:44:53 < BrainDamage> actually what you guys call bolognese is what we call ragu, ragu is a class of tomato and meat sauces
2018-03-21T01:45:08 < BrainDamage> while ragu alla bolognese is a specific one, which has mirepoix as its base

2018-03-21T01:52:49 < BrainDamage> for 4 people: get 300g beef coarsely chopped, best if you use a fattier cut, don't go for the loins, it's wasted, half a glass of white wine best if dry, 300g of tomatoes canned is fine chunky is better,  150g pork belly, 50g fennel, 50g white onion, 50g carrot. first cook the pork belly in its own fat for few minutes until the grease leaks out and it starts frying, add the mirepoix finely chopped along with a few teaspoons of oil to inc
2018-03-21T01:52:49 < BrainDamage> rease the amount of liquid and let sautee until the onion has turned golden. add the beef and cook it until the water content has been cooked off. add the wine and let it boil off some alcohol for some minutes, then add the tomatoes, let it simmer for at least 30 min, 1h better, add broth to compensate for evaporation, add salt only near the end after tasting because depending on the broth amount the salt content will differ
2018-03-21T01:53:49 < upgrdman> thx
2018-03-21T01:54:03 < Ultrasauce> well now i'm hungry
2018-03-21T01:54:04 < BrainDamage> once the sauce is done, cook pasta like usual, make sure to reserve some of the cooking water since it's starch rich

2018-03-21T01:54:42 < BrainDamage> take a frying pan, throw it on your strongest burner with the sauce, the pasta and a ladleful of the starch water
2018-03-21T01:54:52 < BrainDamage> then start tossing the pasta
2018-03-21T01:54:53 < upgrdman> o
2018-03-21T01:55:48 < BrainDamage> it's optional and often skipped in a home cooking, but it really gives a unique flavour, nearly every restaurant here does it
2018-03-21T01:56:02 < upgrdman> toss for how long
2018-03-21T01:56:07 < englishman> yes using pasta water is great
2018-03-21T01:56:25 < BrainDamage> 3-5 min, you'll literally hear it when it's ready
2018-03-21T01:56:36 < BrainDamage> because the sauce will have firmed up and you'll hear the bubbles
2018-03-21T01:56:44 < upgrdman> ah
2018-03-21T01:56:50 < BrainDamage> you can still go for about a minute after
2018-03-21T01:57:02 < BrainDamage> the more you wait the stronger the flavour and the thicker sauce will be
2018-03-21T01:57:38 < upgrdman> also i dont drink wine. what does "dry" mean
2018-03-21T01:57:48 < Ultrasauce> like a powder, duh
2018-03-21T01:57:51 < BrainDamage> dry vs sweet refers to the taste
2018-03-21T01:58:37 < BrainDamage> dry tend to have a strong flavour but it's kind of flat if you were to plot the perception in time
2018-03-21T01:59:23 < upgrdman> looks so good  https://imgur.com/gallery/CNWhS
2018-03-21T01:59:25 < BrainDamage> sweet wines instead the flavour is more subtle and complex, as in different sensations change as it dissolves over the tongue
2018-03-21T02:01:08 < BrainDamage> oh, i mistranslated, it's celery, not fennel
2018-03-21T02:01:10 < BrainDamage> but yeah
2018-03-21T02:01:17 < upgrdman> k
2018-03-21T02:07:05 < englishman> when you buy cooking wine there will be two boxes, one is dry
2018-03-21T02:07:05 < BrainDamage> if you want my fav pasta sauce instead: take 2 large red bell peppers and and roast them until charred, then add 2 tablespoons of olive oil and 1 red chily and toss them while still cooking for about a minute, then take the oil and the roasted peppers in a blender and add 100g of ricotta, salt, a shitload of pepper ( about half a teaspoon ), 1 pinch of hot paprika, 1 tablespoon of water and blend together
2018-03-21T02:07:07 < englishman> the other is wet
2018-03-21T02:07:50 < BrainDamage> oh and a tablespoon of broth
2018-03-21T02:08:18 < BrainDamage> if done properly it's hot and sweet, you just dump it over the drained pasta using a ridicolous amount

2018-03-21T05:47:48 < jadew> which btw, is rarely updated so the information may be incorrect
2018-03-21T05:48:02 < dongs> i bet half of the shit on that page is beyond incorrecet
2018-03-21T05:48:20 < dongs> not that i would care or anything
2018-03-21T05:48:28 < dongs> i was just gonna try and drive it from STm32 or something
2018-03-21T05:48:46 < jadew> probably a lot easier than setting it up on linux

2018-03-21T05:51:19 < jadew> Rob235, what's that?
2018-03-21T05:51:53 < Rob235> stepper and rail mount for my drawing bot
2018-03-21T05:52:50 < jadew> how big is that print bed?
2018-03-21T05:52:53 < jadew> it looks huge
2018-03-21T05:53:25 < Rob235> 220x220
2018-03-21T05:54:00 < jadew> I guess that tape is not as wide as I think it is
2018-03-21T05:54:32 < jadew> so what's your print bot going to do? is it a pen printer?
2018-03-21T05:54:41 < jadew> *draw bot
2018-03-21T05:54:46 < jadew> like the old HPs?
2018-03-21T05:55:40 < Rob235> yea pen plotter, not sure what old HP you are referring to
2018-03-21T05:55:53 < Rob235> https://i.imgur.com/KDJPwOw.png
2018-03-21T05:55:59 < jadew> HP used to have a line of pen plotters in the past
2018-03-21T05:56:06 < Rob235> https://i.imgur.com/WAS0Ez2.png
2018-03-21T05:56:10 < jadew> most HP instruments know how to plot on one of those
2018-03-21T05:56:57 < jadew> I don't think they used actual pens
2018-03-21T05:57:18 < Rob235> I made a collet system to take different sized markers/pens
2018-03-21T05:57:45 < Rob235> shit I forgot to add something :/ oh well guess this print will have less detail, it was only for looks anyway
2018-03-21T05:57:52 < jadew> http://www.dilette.com/main/dilettesales/HP_7470A_Plotter.html
2018-03-21T05:58:37 < jadew> the way you print on one of those is by sending move commands to the pen
2018-03-21T05:58:44 < Rob235> in my old version these towers had indentations where I was gonna snap lines of bricks going vertically at each corner of the octagon so I could add a secondary color
2018-03-21T05:58:52 < Rob235> completely forgot so the walls are just flat
2018-03-21T05:58:55 < jadew> you can draw lines, arcs, things like that
2018-03-21T05:59:11 < Rob235> ahh I see
2018-03-21T05:59:45 < jadew> depending on what this is for, you may consider supporting their protocol
2018-03-21T06:00:03 < Rob235> I'm adding an esp8266 to mine and designing a website to control it.  I have a mockup of half of it working ( http://www.robertfeddeler.com ) You can load up jpg/png/bmp and it converts it to lines or load svg and convert to my own gcode type format
2018-03-21T06:01:04 < jadew> you know what would be useful? if it was super cheap, didn't look bad and could draw on a whiteboard
2018-03-21T06:01:38 < jadew> it would probably be easier to get a smart whiteboard tho
2018-03-21T06:01:44 < Rob235> it started out as a quick school project but I decided to make it a lot more detailed.  the school aspect is for my capstone using simulated annealing to find the fastest order to draw the lines in using two separate arms that cover the same area and have them draw together without bumping into each other
2018-03-21T06:02:16 < Rob235> yea theres a lot of those hanging vertical style ones, I dont really like those as much as horizontal
2018-03-21T06:02:36 < jadew> oh, there are already solutions for that?
2018-03-21T06:02:39 < Rob235> this is basically an axidraw v3 that I'm doing from scratch that has two of them working together
2018-03-21T06:02:43 < Rob235> yup

2018-03-21T06:05:45 < jadew> that could be useful
2018-03-21T06:06:01 < jadew> but I guess now with huge 4k TVs being so cheap, it reduces their utility
2018-03-21T06:06:39 < jadew> I felt the need for such a printer when I was looking through some huge schematics
2018-03-21T06:06:41 < Rob235> alright time for bed, I hope this print doesnt fail, never left it on when I wasnt here and awake so if I never come back you know I died horribly in a fire
2018-03-21T06:07:12 < Rob235> yea I wasnt aware how common these things were when I started this project but oh well, its been fun
2018-03-21T06:07:13 < jadew> farewell
2018-03-21T06:08:53 < jadew> another use for something like this: any size printer
2018-03-21T06:09:28 < jadew> you take a sheet of paper, however large you want, put 4 heavier things around the corners, it calibrates itself and starts printing
2018-03-21T06:09:33 < jadew> (I'd buy that)

2018-03-21T09:12:08 < stm32f072> and SWCLK..

2018-03-21T09:17:59 < zyp> stm32f072, what's your experience level so far?
2018-03-21T09:18:19 < zyp> what hardware are you going to hook up to your board to put your firmware on it?

2018-03-21T09:20:13 < stm32f072> so far I only used the nucleo boards, I guess I can disconnect the programmer on the nucleo and jumpwire it with my custom board afterwards
2018-03-21T09:20:36 < zyp> yes
2018-03-21T09:21:32 < zyp> at a minimum, you're then going to have to jumpwire SWDIO, SWCLK and GND
2018-03-21T09:22:29 < stm32f072> what is the boot0 pin for?
2018-03-21T09:22:45 < stm32f072> I see it's only wired with the pinheaders but not the stlink interface
2018-03-21T09:22:52 < zyp> you might also want NRST, and it's normal to provide VCC also in case you're using debugger hardware with a voltage buffer
2018-03-21T09:23:18 < zyp> stm32f0 doesn't have SWO, otherwise that'd also be normal to provide, for six signals in total
2018-03-21T09:23:37 < stm32f072> So I will do the same NRST/TCK/TMS/SWO/STLK_RX/STLK_TX/MCO .. hmm MCO I have disconnected I think
2018-03-21T09:23:55 < stm32f072> MB1136.pdf shows up SWO?
2018-03-21T09:24:18 < zyp> where? got an url?

2018-03-21T09:24:54 < stm32f072> STM32 Nucleo (64 pins) schematics
2018-03-21T09:25:39 < zyp> ah, this is a common layout that fits multiple 64-pin stm32 chips, isn't it?
2018-03-21T09:26:10 < zyp> cortex-m0/m0+ does not have SWO, but m3, m4 and m7 does
2018-03-21T09:26:12 < stm32f072> I only have STM32L0 and STM32F0 nucleos here, not sure about other ones
2018-03-21T09:26:31 < zyp> so it's probably hooked up just for the chips that are able to make use of it
2018-03-21T09:27:36 < zyp> MCO you're not gonna need
2018-03-21T09:28:46 < stm32f072> I see I will also route it for future use then (possibly if I'll ever use another STMFx version)
2018-03-21T09:28:51 < zyp> on the nucleo, MCO is used to provide an 8MHz clock from the stlink part to the target mcu, that's why it feeds into OSC_IN (PF0)
2018-03-21T09:28:56 < PaulFertser> But if all you're after is "putting firmware on a chip" and you have UART routed anyway, probably it'd better to flash it via the serial bootloader.
2018-03-21T09:29:05 < stm32f072> I tried to use the STMF4 first, but the STM32F0 just performs nicely
2018-03-21T09:29:09 < zyp> PaulFertser, no.

2018-03-21T09:30:28 < zyp> PaulFertser, strictly what you're saying makes sense, but I wouldn't suggest to a learner that they design a board that they won't be able to hook a debugger to in the future
2018-03-21T09:31:40 < zyp> from my perspective, he's asking for a way to flash the board, but what he really wants is a way to debug it, he's just not experienced enough to know
2018-03-21T09:31:58 < PaulFertser> zyp: it's him saying he only needs to "put firmware on a chip", not me. Of course I wouldn't recommend anyone (learner or pro) to not use OCD.
2018-03-21T09:32:34 < zyp> that's why you need to read between the lines sometimes and not just reply to the strictly stated question
2018-03-21T09:33:14 < dongs> pmp it up
2018-03-21T09:33:16 < dongs> zyp: my shit show up?
2018-03-21T09:33:21 < dongs> any fails
2018-03-21T09:33:23 < zyp> ya, arrived yesterday
2018-03-21T09:33:41 < zyp> dunno, still in the box, people are coming to pick it up today
2018-03-21T09:33:57 < PaulFertser> But he already has nucleos so he has probably fully debugged the firmware and just wants to build a board of minimal size with the same chip. That said, I'd still route out SWD to at least testpoints.
2018-03-21T09:34:30 < zyp> PaulFertser, doubt that it is "fully debugged" in any sense :)

2018-03-21T09:34:48 < stvn> You listen here and you listen good
2018-03-21T09:34:57 < dongs> < zyp> ah, this is a common layout that fits multiple 64-pin stm32 chips, isn't it?
2018-03-21T09:35:00 < dongs> yeah it is
2018-03-21T09:35:47 < zyp> yeah, schematic has a bunch of solder bridges to account for various chips
2018-03-21T09:36:45 < zyp> stm32f072, if I were you, I would probably use a six-pin header with the same pinout as CN4 in your schematic
2018-03-21T09:37:16 < dongs> if I was them I'd use a standard cortex-m debug socket, but thats jsut me
2018-03-21T09:37:18 < dongs> :)
2018-03-21T09:37:29 < zyp> i.e. VCC, SWCLK, GND, SWDIO, NRST, SWO
2018-03-21T09:37:40 < zyp> but then leave SWO pin unconnected since you don't have it
2018-03-21T09:38:28 < zyp> the standard cortex-m debug socket is also a good option, but then you need a fitting cable
2018-03-21T09:39:51 < stvn> I miss mine
2018-03-21T09:40:06 < dongs> if youre in nucleo/stdink ecosystem, 6 pin shit makes sense
2018-03-21T09:40:13 < dongs> since you can just jumper it off a nother board
2018-03-21T09:40:26 < zyp> yes, that's what I'm arguing
2018-03-21T09:40:37 < stm32f072> that STM datasheet looks odd, U5A U5B they split one component into 2 I wonder how Altium can handle that
2018-03-21T09:40:49 < zyp> just fine
2018-03-21T09:40:57 < zyp> just make a multi symbol component
2018-03-21T09:41:45 < zyp> it's very normal to split large components into multiple symbols, both in altium and in other tools
2018-03-21T09:41:51 < stm32f072> MCO is just routed for fun on the nucleos no?
2018-03-21T09:42:05 < zyp> like I said, it's used to save a crystal
2018-03-21T09:42:29 < zyp> instead of providing a 8MHz crystal for the target mcu, it's just fed 8MHz from the stlink part
2018-03-21T09:42:44 < dongs> there's a footprint for 8mz shit tho
2018-03-21T09:43:00 < zyp> it's possible to do that because the stlink exists on the same board
2018-03-21T09:43:03 < stvn> stink
2018-03-21T09:43:17 < zyp> but if you did that on your own board, you'd need to always have the stlink connected, otherwise it wouldn't run
2018-03-21T09:43:19 < stm32f072> it's needed?
2018-03-21T09:43:36 < zyp> no, what you really need is a different sysclk source
2018-03-21T09:43:53 < zyp> on f072, you can just use one of the internal oscillators
2018-03-21T09:44:27 < stm32f072> ok that's what I thought... so just routed for fun on the stm32f072/L073
2018-03-21T09:45:09 < zyp> "for fun" is a bit too simple
2018-03-21T09:45:30 < zyp> I'd say it's routed to provide an 8MHz HSE
2018-03-21T09:45:34 < stm32f072> so finally I should have a connector:  VCC, SWCLK, GND, SWDIO, NRST
2018-03-21T09:45:45 < zyp> whether you need an 8MHz HSE or not depends on your application
2018-03-21T09:45:57 < zyp> yes, that sounds like a good starting point
2018-03-21T09:46:17 < stm32f072> great thanks :-)

2018-03-21T11:36:51 < karlp> eyah, didn't see any reason for this to be on stm32
2018-03-21T11:37:32 < psprint> I have 1602a LCD bought with arduino starter kit, it's probably 5V hardware, can I use it with STM32F07 ?
2018-03-21T11:38:04 < BrainDamage> yes, stm32 are 5v tollerant, you just have to use pullups and open drain mode
2018-03-21T11:38:39 < psprint> cool, thanks
2018-03-21T11:38:42 < BrainDamage> make sure to check the actual pin 5V tollerance, which is not guaranteed for every port
2018-03-21T11:38:52 < psprint> ok
2018-03-21T11:40:48 < qyx> counting devices on a network segment
2018-03-21T11:41:04 < qyx> I am curious how secure is that
2018-03-21T11:42:24 < psprint> it's one of the elements, basic information, other is ping-scan, then arp-listing devices (might require router cooperation), checking MAC addresses. Basic *eye* on network
2018-03-21T11:42:28 < qyx> somehow it is hard to imagine how a security engineer comes to a switch, plugs in a box and looks on a lcd to check devices on the network
2018-03-21T11:42:48 < qyx> there are mature tools for that
2018-03-21T11:43:18 < qyx> free and payware
2018-03-21T11:43:23 < psprint> it's to stop most basic thing, that one can connect to wifi totally without anyone aware, a basic line of defense
2018-03-21T11:43:56 < psprint> qyx: an example of such tool?
2018-03-21T11:43:56 < qyx> I understand, but thats not the way things are done
2018-03-21T11:44:22 < qyx> nessus scanner for example
2018-03-21T11:44:54 < BrainDamage> snort if you want saucy stuff
2018-03-21T11:45:18 < BrainDamage> you generally don't just whitelist devices, you whitelist the traffic too
2018-03-21T11:45:24 < qyx> certainly if I want to harden my wifi hotspot I will not attach a station counter to it
2018-03-21T11:45:46 < psprint> ah yes, those scanner, was aware of them 10 years ago, used even something like "fscanner" or "ffscanner", which indexed anything on Windows Share, I had multiple blocks in my area on the same or accessible network, and people just didn't bother with passwords to *some* extent (not a dramatic one)
2018-03-21T11:46:29 < psprint> or "ffsearch"
2018-03-21T11:46:38 < qyx> pff just count them
2018-03-21T11:48:09 < psprint> other point of view, with todays number of devices and fluctuations it have, knowing the number and its behavior, I think it's ok, 10 years ago it would be just "1" or "2", now it's much more
2018-03-21T11:51:54 < dongs> < stvn> aut.ism
2018-03-21T11:51:57 < dongs> best answer
2018-03-21T11:52:16 < stm32f072> hmm does anyone know about the USB interface of the stm32f0 series? if I connect my device without any firmware loaded I can upload it initially via USB 1.1 as well?
2018-03-21T11:52:24 < dongs> yes
2018-03-21T11:52:30 < dongs> when flash is blank
2018-03-21T11:52:33 < dongs> it jumps to usb bootloader
2018-03-21T11:52:48 < dongs> can confirm on F042K6 at least beacuse thats how i flash my boards with that chip and USB
2018-03-21T11:53:34 < stm32f072> whow that's cool so I could just skip the entire debugging interface
2018-03-21T11:53:49 < qyx> you will regret that
2018-03-21T11:55:15 < kaa> psprint, tell me if you find such device

2018-03-21T12:55:25 < kaa> what do you think about using a shunt regulator instead of zener to clamp 3v3 power line?
2018-03-21T12:56:05 < kaa> I have like 5 seperate ADC lines clamped to it and those can probs push milliamps to that 3v3 line
2018-03-21T12:56:31 < kaa> especially at transients
2018-03-21T12:57:57 < kaa> currently I run MCU with 3v0 and clamping with zener around 3v6
2018-03-21T12:58:53 < kaa> I want to bring operating voltage and clamping voltage closer
2018-03-21T13:00:57 < kaa> and keep losses low
2018-03-21T13:01:27 < kaa> I plan to have it sleep with Iq under 100µA
2018-03-21T13:01:42 < kaa> not 1mA

2018-03-21T13:22:46 < jpa-> kaa: for transients i would just calculate that decoupling caps can take it, but if you need many milliamps of DC going there, then shunt regulator sounds like a reasonable idea
2018-03-21T13:22:56 < jpa-> i'd probably just have a separate clamping rail with zener, though
2018-03-21T13:23:12 < kaa> I keep lines minimal
2018-03-21T13:23:29 < kaa> 2 side design with 1side layout
2018-03-21T13:26:08 < jpa-> ok
2018-03-21T13:26:13 < kaa> I need to concider having a zener line
2018-03-21T13:26:18 < kaa> or multiple
2018-03-21T13:26:29 < kaa> zeners are cheaper than routing that shiet
2018-03-21T13:26:44 < jpa-> TL431A or similar on 3.3V line is a simple enough fix then
2018-03-21T13:28:25 < kaa> zeners are not good for milliamperes of clamping

2018-03-21T17:02:31 < Rob235> for under 200 bucks theres really no reason not to, just print some upgrades when you first get it and you can slowly upgrade other stuff over time

2018-03-21T20:41:52 < Laurenceb> qyx: too noisy
2018-03-21T20:42:09 < Laurenceb> the pll cant lock until the frequency sweep is outside of the lock range
2018-03-21T20:42:21 < Laurenceb>  - the signal amplitude increases with frequency
2018-03-21T20:42:47 < Laurenceb> but looking at the signal something is wrong
2018-03-21T20:44:37 < Laurenceb> https://imgoat.com/uploads/6657d5ff90/95753.png
2018-03-21T20:44:56 < Laurenceb> thats the real and complex baseband - pre baseband filtering
2018-03-21T20:45:05 < Laurenceb> that should be lockable

2018-03-21T20:45:40 < Cracki> looks noisy as fuck
2018-03-21T20:45:49 < Laurenceb> yeah but good enough for a pll to lock

2018-03-21T20:48:42 < Laurenceb> maybe I should pre filter
2018-03-21T20:48:51 < Ultrasauce> add hysteresis
2018-03-21T20:48:51 < Laurenceb> yeah, kill the high frequency noise pre pll

2018-03-21T21:02:04 < Laurenceb> yesterday it looked pretty...
2018-03-21T21:02:14 < Laurenceb> nasty haxor in progress...
2018-03-21T21:02:24 < Cracki> yikes
2018-03-21T21:02:37 < Cracki> at least it's not _one_ single function :>
2018-03-21T21:02:54 < Laurenceb> tbh I hate it when you see a bazillion methlab files
2018-03-21T21:03:17 < Laurenceb> most of which are doing nothing much but renaming stuff
2018-03-21T21:03:21 < Laurenceb> all pastry and no meat
2018-03-21T21:04:20 < Cracki> that's the beauty of not having classes, no hammerfactory
2018-03-21T21:06:33 < Laurenceb> nice

2018-03-21T21:28:05 < Laurenceb> closer to working
2018-03-21T21:29:23 < Laurenceb> pll loses lock half way through
2018-03-21T21:29:24 < Laurenceb> weird
2018-03-21T21:30:55 < Cracki> plot all the values :P
2018-03-21T21:31:05 < Laurenceb> dunno why its oscillating so much when mems pll is stable
2018-03-21T21:31:14 < Laurenceb> heh I already killed opengl once
2018-03-21T21:31:16 < Cracki> numerics problem?
2018-03-21T21:31:28 < Cracki> first half looked "in trouble"
2018-03-21T21:31:48 < Laurenceb> yeah its screwy
2018-03-21T21:31:55 < Laurenceb> thats the real output of the pll
2018-03-21T21:31:56 < Cracki> if second half is loss of lock, and it looks *better*, that's weird
2018-03-21T21:32:06 < Laurenceb> should be positive
2018-03-21T21:32:07 < Cracki> uh, phase error, or what
2018-03-21T21:32:22 < Cracki> it looked sensible up to .5e6
2018-03-21T21:32:36 < Cracki> then looked like it jumped to a multiple/fraction or something
2018-03-21T21:32:51 < Laurenceb> I know what that is - its the shaker adjusting
2018-03-21T21:33:00 < Laurenceb> it has some crude AGC built in
2018-03-21T21:33:20 < Cracki> fascinating
2018-03-21T21:34:04 < Laurenceb> oh shit I think maybe shaker guys are trolling me
2018-03-21T21:34:15 < Laurenceb> and they have frequency discontinuities
2018-03-21T21:34:32 < Laurenceb> time to search through the mems pll data
2018-03-21T21:37:28 < Cracki> wat? like suddenly changing frequency? that's what the spectrogram looked like anyway
2018-03-21T21:37:38 < Laurenceb> hmm time to plot
2018-03-21T21:37:39 < Cracki> pll should tolerate, no?
2018-03-21T21:37:46 < Laurenceb> yeah
2018-03-21T21:39:02 < Laurenceb> something is screwy with the IEPE data :-/
2018-03-21T21:39:20 < Laurenceb> grr I with methlab was multicore

2018-03-21T21:48:34 < blacktronics> tbh having a 3D printer is quite nice, i barely use mine but on occasion i am glad i have it
2018-03-21T21:48:38 < Rob235> I didnt just print a castle, I just happened to design my pen plotter like a castle :/
2018-03-21T21:49:38 < blacktronics> If you got the tools at your disposal you'll use em

2018-03-21T21:50:10 < Rob235> I havent even had time to print other peoples 'toys' on thingiverse, I'm too busy with my own, Id like to try some premade shit though

2018-03-21T22:19:21 < Steffanx> mems audio much?
2018-03-21T22:19:27 < Laurenceb> IEPE
2018-03-21T22:19:33 < Laurenceb> mems is working ok
2018-03-21T22:19:47 < Laurenceb> I suspect as there is horizontal vibration
2018-03-21T22:20:00 < Laurenceb> IEPE has only about 6dB horizontal reject ratio
2018-03-21T22:20:45 < Laurenceb> I'm going to have to ask them to let me fit my jigs onto the shaker...
2018-03-21T22:20:52 < Laurenceb> its designed to solve these issues
2018-03-21T22:22:19 < Cracki> what stupid kinda sensor is that? why not just slap some digital mems accelerometer on it?
2018-03-21T22:23:09 < Cracki> I've read a bit on wikipedia about iepe, sounds "industrial", like you measure in one place, make a voltage, and adc that somewhere else entirely
2018-03-21T22:24:38 < Laurenceb> Cracki: IEPE has really good phase and amplitude response
2018-03-21T22:24:42 < Laurenceb> its good to 15khz
2018-03-21T22:24:48 < Cracki> hm
2018-03-21T22:24:56 < Laurenceb> I'm trying to characterise frequency response
2018-03-21T22:24:58 < Cracki> so... do you need that?
2018-03-21T22:25:06 < Laurenceb> yes

2018-03-21T22:25:18 < Laurenceb> mems versus iepe
2018-03-21T22:25:29 < Cracki> uhhh wat's red and blue?
2018-03-21T22:25:47 < Cracki> that blue squiggle almost looks like a sine
2018-03-21T22:25:56 < Laurenceb> red is mems, blue iepe
2018-03-21T22:25:59 < Cracki> lol
2018-03-21T22:26:24 < Cracki> where does the noise come from?
2018-03-21T22:26:24 < Laurenceb> I tihnk they might have fuxored the mounting
2018-03-21T22:26:51 < Laurenceb> that or there is wobbling thats significant as the devices arent in the same place
2018-03-21T22:26:58 < Cracki> sample rate looks a bit low
2018-03-21T22:27:03 < Laurenceb> yeah
2018-03-21T22:27:14 < Laurenceb> I told them to up it...
2018-03-21T22:27:26 < Laurenceb> such a failproject
2018-03-21T22:27:32 < Cracki> nah, 640k should be enough for anyone
2018-03-21T22:27:42 < Laurenceb> 2ksps for the iepe
2018-03-21T22:27:59 < Cracki> digital mems can do 2 ksps

2018-03-21T22:28:23 < Cracki> how are you gonna get to measure 15 khz tho
2018-03-21T22:28:40 < Laurenceb> I'm not, its just smooth to 500hz for sure

2018-03-21T23:58:51 < catphish> but not well :(
2018-03-21T23:59:08 < kaa> catphish, after you are done wipe that shiet of with acetone + toothbrush
2018-03-21T23:59:12 < ds2> has anyone messed with sinograms and inverse radson (sp?) transforms
2018-03-21T23:59:27 < kaa> then rinse it with asetoce
2018-03-21T23:59:57 < catphish> that's probably a good idea, it's covered in burnt flux

2018-03-22T00:00:17 < kaa> at least all those smds can handle acetone

2018-03-22T00:01:11 < Rob235> thats the only reason I have access to any
2018-03-22T00:01:16 < catphish> i was planning to use ethanol
2018-03-22T00:01:26 < kaa> try that
2018-03-22T00:01:34 < kaa> and isopropanole also
2018-03-22T00:02:03 < kaa> but those tend to be pretty inefficient compared to acetone exploding that all away
2018-03-22T00:02:38 < kaa> I use acetone + isopropanole
2018-03-22T00:02:42 < kaa> mixed
2018-03-22T00:03:26 < kaa> And good work catphish! That thing looks brutal. I'm proud of you

2018-03-22T00:20:30 < kaa> because I'm kinda doing some high current device that is pain in the ass to solder because I opted out some high current pad thermal reliefs
2018-03-22T00:20:59 < kaa> that is meant to be a product in like.. 2 rev iterations
2018-03-22T00:27:33 < englishman> karlp: lol
2018-03-22T00:29:02 < aandrew> https://imgur.com/a/dHEXY panel's almost done
2018-03-22T00:29:05 < Cracki> thermal reliefs do matter a bit if you bake it. you wanna spend just a few seconds in reflow.
2018-03-22T00:29:25 < aandrew> preheating the board helps a LOT
2018-03-22T00:29:29 < Cracki> it does
2018-03-22T00:29:42 < Cracki> still, for baking, the same principles apply
2018-03-22T00:30:18 < Cracki> (just not nearly as severe as for hand soldering)
2018-03-22T00:36:03 < catphish> kaa: it's a good question, i avoided the thermal relief because i was worried about current, but i think actually that was very much the wrong decision :)
2018-03-22T00:36:17 < catphish> kaa: looks like all but one of my joints was good
2018-03-22T00:38:46 < kaa> what I have heard thermal reliefs are so short that most of the time the added loss is acceptable
2018-03-22T00:39:14 < catphish> yeah, i suspect that's the case
2018-03-22T00:39:32 < kaa> if you have 20A current from 4 sides to the part it 5Amps per bridge
2018-03-22T00:39:46 < catphish> well all 6 of the igbt drivers are working
2018-03-22T00:40:04 < catphish> still need to test the current sensors and the IGBTs themselves :)
2018-03-22T00:40:27 < kaa> I use no thermal relief in things that need high current and need to dump as much as possible heat to copper
2018-03-22T00:41:19 < catphish> my board was designed to handle 20A, but i put 5A current sensors on it because i'm not likely to ever use it with more than that and i want accurate readings
2018-03-22T00:42:02 < kaa> and I eyeball copper area and tools I have if I'm able to solder/reflow it on
2018-03-22T00:42:41 < kaa> catphish, how accurate you want?
2018-03-22T00:43:37 < catphish> kaa: i genuinely don't know how accurate it needs to be, the 5A sensor outputs 264mV per amp
2018-03-22T00:43:51 < catphish> that goes into the stm32's ADC
2018-03-22T00:44:10 < catphish> i'll have to test and see what the results are like, and whether they're good enough
2018-03-22T00:44:30 < kaa> if I'm like meh.. I'm not probably able to solder/reflow that then I put thermal relief on that pad and route some fat traces over those thin copper bridges
2018-03-22T00:44:59 < catphish> i'm planning to use it to control AC current, no idea how tight the control needs to be
2018-03-22T00:47:55 < kaa> so you have.. 650mV per current direction?
2018-03-22T00:48:08 < kaa> wait 1,3 per direction
2018-03-22T00:48:12 < kaa> 1.3*
2018-03-22T00:48:22 < catphish> yes
2018-03-22T00:48:47 < catphish> though that's assuming i use all 5A
2018-03-22T00:49:09 < kaa> let's calculate resolution
2018-03-22T00:49:36 < catphish> the ADC is 12 bits, maybe a little more with oversampling
2018-03-22T00:50:03 < kaa> there is a catch with ADC
2018-03-22T00:50:18 < catphish> so worst case, i'd call it 10 bits per direction (assuming it's perfect)
2018-03-22T00:50:24 < kaa> that is closer
2018-03-22T00:51:22 < catphish> so roughly 7-8 bits per amp if it works properly
2018-03-22T00:51:24 < kaa> effective bits - you might have 12bit ADC but it will produce 10-11 effective bits and 1-2 bits garbage

2018-03-22T00:55:35 < catphish> that's just individual 12 bit samples at long intervals over a few seconds
2018-03-22T00:56:00 < kaa> remove last two bits
2018-03-22T00:56:18 < kaa> LSB
2018-03-22T00:57:13 < kaa> also you should run ADC slower
2018-03-22T00:57:15 < catphish> it's uniformly random between 1917->2016
2018-03-22T00:58:00 < kaa> there is some recommended clock rate datasheet
2018-03-22T00:58:12 < kaa> for more accurate measurements
2018-03-22T00:58:46 < catphish> that makes sense, there's probably a few things i can do, this is the most default configuration right now
2018-03-22T00:59:41 < catphish> right now that's nearly 7 bits is noise, which is a bit painful
2018-03-22T01:00:44 < catphish> i'll look at the clock rates, and get the oversampling set up
2018-03-22T01:03:13 < kaa> 7bits of noise?
2018-03-22T01:03:16 < kaa> waa
2018-03-22T01:03:28 < catphish> the measured values are 1917->2016
2018-03-22T01:03:35 < catphish> i count that as 7 bits
2018-03-22T01:04:37 < kaa> correct 8|
2018-03-22T01:04:56 < kaa> did you design any filters to your board?
2018-03-22T01:05:19 < catphish> no
2018-03-22T01:05:35 < kaa> you should always at least have footprints
2018-03-22T01:05:41 < kaa> even when you don't need it
2018-03-22T01:05:49 < catphish> one thing that might help is reducing the impedance of the adc input
2018-03-22T01:06:04 < catphish> it might be nothing but noise on the line between the sensor and the ADC
2018-03-22T01:06:24 < catphish> which is a long line that for some unsmart reason i ran next to some digital lines
2018-03-22T01:06:43 < catphish> one learns
2018-03-22T01:07:38 < kaa> hmm
2018-03-22T01:08:16 < catphish> there's a few things i can do to test, like silencing those digital lines and looking at the difference
2018-03-22T01:11:29 < kaa> you can also try to load that line from another end
2018-03-22T01:11:55 < kaa> 10k resistor to ground or so
2018-03-22T01:12:32 < catphish> that may be the answer, i'll give it a try, the supply should be fairly low impedamce i think
2018-03-22T01:12:59 < kaa> usually those can drive milliamps without any issues
2018-03-22T01:13:04 < catphish> silencing the digital lines made no difference
2018-03-22T01:13:24 < catphish> so hopefully this is something i can fix with small hardware / software modifications
2018-03-22T01:14:11 < kaa> you need to check if that beast has even built in low pass filter option
2018-03-22T01:14:39 < kaa> even that.. it has literally everything
2018-03-22T01:14:56 < catphish> at least the noise is consistent
2018-03-22T01:15:24 < catphish> hopefully i can track it down
2018-03-22T01:15:28 < zyp> catphish, do you have a proper antialiasing filter in front of the ADC?
2018-03-22T01:15:36 < catphish> i do not
2018-03-22T01:16:02 < zyp> how do you expect to get accurate readings then?
2018-03-22T01:16:13 < catphish> i don't know yet
2018-03-22T01:16:37 < kaa> could resistor and cap to ground work?
2018-03-22T01:16:42 < kaa> as a hack
2018-03-22T01:16:59 < catphish> i had hoped the filtering in the ACS was all i'd need, but maybe that's at the wrong end of a line
2018-03-22T01:17:09 < kaa> certainly
2018-03-22T01:17:26 < kaa> you always filter as close as possible to actual ADC pin
2018-03-22T01:17:27 < zyp> have you looked at the ADC input with a scope or something?
2018-03-22T01:17:40 < ds2> sigh... why can't ADCs be more idea
2018-03-22T01:18:11 < zyp> because analog is imperfect :)
2018-03-22T01:18:40 < catphish> i see one huge problem
2018-03-22T01:19:21 < kaa> something is not connected?
2018-03-22T01:19:27 < catphish> the ACS has a bandwidth selection pin, some models expect a capacitor on it, this one expects it to be tied high or low, i left it floating
2018-03-22T01:19:54 < kaa> do you have something to bind it to right next to it?
2018-03-22T01:20:03 < catphish> yep
2018-03-22T01:20:38 < kaa> do datasheet recommend a resistor between them?
2018-03-22T01:20:54 < kaa> in example design or so
2018-03-22T01:21:01 < kaa> or just direct connection?
2018-03-22T01:21:18 < catphish> my original design was for a part that expected a capacitor to ground, so i made a pad for that
2018-03-22T01:21:48 < catphish> but that part wasn't available, this one is pin compatible but expects a short to ground or vcc
2018-03-22T01:22:09 < catphish> so i can short my original pad, or add a wire to vcc easily
2018-03-22T01:22:32 < kaa> if it fits - it sits
2018-03-22T01:22:52 < catphish> well, that'll teach me to read closer

2018-03-22T01:30:08 < catphish> they don't provide a PCB layout recommendation, having VCC and one end, GND at the other, and data in the middle is a tad inconvenient
2018-03-22T01:30:10 < kaa> you can get something like 0402 0ohm jumpers also to fit a jumper snugly right next to pins
2018-03-22T01:30:59 < kaa> catphish, in 2 sided layout you can throw 0603 right under it

2018-03-22T01:32:39 < kaa> it should be fine
2018-03-22T01:32:58 < kaa> but in principle you should do it in other way
2018-03-22T01:36:31 < zyp> catphish, what ADC sample rate are you running?
2018-03-22T01:37:34 < catphish> zyp: stupid answer: i don't know, i'm using the default configuration with an 80MHz clock, and just request samples on demand

2018-03-22T01:39:51 < catphish> the datasheet claims it can do full 12 bit resolution at 5.33 Ms/s though
2018-03-22T01:40:02 < zyp> so your signal has an analog bandwidth up to either 20kHz or 80kHz

2018-03-22T01:40:48 < Laurenceb__> ah
2018-03-22T01:41:00 < Laurenceb__> ENOB at 5.33Msps is not going to be 12
2018-03-22T01:41:13 < Laurenceb__> F1 can manage close ot 11 at 1Msps

2018-03-22T01:43:53 < Laurenceb__> newer F4 is slightly worse than F1 adc noise wise
2018-03-22T01:43:55 < catphish> zyp: the results appear the same with that pin tied crudely to ground, or floating
2018-03-22T01:43:56 < Laurenceb__> but adc is faster
2018-03-22T01:44:04 < Laurenceb__> dont know about L4, never tested it
2018-03-22T01:44:28 < Laurenceb__> early F4 was shit tier
2018-03-22T01:44:39 < catphish> right now i really think this is either the result of the line not being terminated properly, or some poor software setup
2018-03-22T01:44:50 < zyp> remember the sampling theorem; when you're sampling at 100Hz, you'll only get 50Hz of bandwidth, and any energy at higher frequencies will alias into the 50Hz spectrum and show up as noise

2018-03-22T01:45:57 < zyp> if you don't have a proper antialiasing filter in front of the ADC, you'll want to sample at a much higher frequency, do a software low-pass, then downsample to 100Hz
2018-03-22T01:46:01 < Laurenceb__> many manufacturers bullshit about adc performance, ST tell the truth
2018-03-22T01:46:05 < Laurenceb__> its very good
2018-03-22T01:47:54 < zyp> at least that's my take of this, but to be honest I don't have much practical experience with analog shit, I tend to avoid it if I can :)
2018-03-22T01:48:28 < catphish> zyp: thanks
2018-03-22T01:48:37 < catphish> i'll have a play with software options first

2018-03-22T02:56:27 < catphish> kaa: thanks for all the help, it looks like i can make some improvement by running the ADC slower, and oversampling, i'll also add some software low pass filtering, and hopefully i'll be good for now
2018-03-22T02:57:33 < catphish> it's a shame really, had hoped for better, but my hardware design probably lets me down :)

2018-03-22T03:16:13 < R0b0t1> Can anyone give me some general advice on how to use X-CUBE-MEMSMIC1 (http://www.st.com/en/embedded-software/x-cube-memsmic1.html)?
2018-03-22T03:16:24 < R0b0t1> How do I use it from within STMCubeMX
2018-03-22T03:16:43 < R0b0t1> I downloaded the files themselves but it seems like I should be able to select it as an additional middleware in the GUI
2018-03-22T03:26:57 < Laurenceb__> >using CUBE
2018-03-22T03:27:08 < Laurenceb__> sound horrifying tbh
2018-03-22T03:27:25 < Laurenceb__> its semi useful for shit like usb
2018-03-22T03:27:39 < Laurenceb__> but for a standalone board I'd write ur own codez using cube functions
2018-03-22T03:32:05 < R0b0t1> That is what I was working towards
2018-03-22T03:32:19 < R0b0t1> There does not seem to be any documentation besides the generated projects is the main issue
2018-03-22T03:32:55 < R0b0t1> libopencm3 doesn't support most L4 devices yet so I am using the STM libraries for USB
2018-03-22T03:33:18 < R0b0t1> Coincidentally they also have completely working microphone code
2018-03-22T03:33:33 < Laurenceb__> interesting
2018-03-22T03:33:41 < Laurenceb__> I spent ages writing micrphone support
2018-03-22T03:33:55 < R0b0t1> So you see why I'm interested right

2018-03-22T03:57:44 < R0b0t1`> You have a lathe, branjb?
2018-03-22T03:57:54 < branjb> no, that would make it super easy though haha
2018-03-22T03:58:11 < branjb> I have a hand drill, dremel, table saw, and miter saw
2018-03-22T03:58:20 < R0b0t1`> You really should buy them the right size, they are case hardened
2018-03-22T03:58:30 < branjb> supposedly guys were doing this with shitty 12V hand drills but my bit didn't even scratch the acme
2018-03-22T03:58:44 < R0b0t1`> They were buying cheap lead screws
2018-03-22T04:00:03 < R0b0t1`> So to make a lead screw they turn it on a big lathe and then fix the ends (and should harden it).
2018-03-22T04:00:46 < Laurenceb__> protip: avoid cheap drill presses
2018-03-22T04:00:53 < Laurenceb__> those things make me rageeee
2018-03-22T04:00:58 < branjb> my leadscrew is fine
2018-03-22T04:01:09 < branjb> I am trying to pull it tight to put it in tension
2018-03-22T04:02:10 < Laurenceb__> >start drilling hole
2018-03-22T04:02:11 < R0b0t1`> I would not mount it under tension
2018-03-22T04:02:20 < Laurenceb__> >finish drilling hole 0.5mm away
2018-03-22T04:02:29 < R0b0t1`> You need to use rails, the lead screw will flop around a bit even if it is mounted properly
2018-03-22T04:02:43 < Laurenceb__> shitty bearings and flexing frame on the cheap drill presses
2018-03-22T04:02:46  * Laurenceb__ zzz
2018-03-22T04:02:50 < R0b0t1`> The rails can be made straight
2018-03-22T04:03:04 < branjb> even a shitty drill press would be a step up from trying to hand drill
2018-03-22T04:03:13 < R0b0t1`> The lead screw is harder to make straight and have it be able to mounted
2018-03-22T04:03:21 < branjb> I don't care if it's straight

2018-03-22T04:04:53 < R0b0t1`> If you buy linear motion assemblies, all I have worked with have the lead screw flop around a bit.
2018-03-22T04:05:20 < R0b0t1`> It's kind of secured on the far side across from the motor with something inside it but it is mostly supported in a bearing

2018-03-22T17:02:02 < zyp> catphish, what did you try=
2018-03-22T17:03:43 < catphish> zyp: so far just slowing down the ACD clock (which helps but only to the extent of about 1 bit) and oversampling, which only works over such a long period that it makes the sample rate much too slow
2018-03-22T17:04:28 < zyp> did you try sampling faster and doing a proper software lowpass filter?
2018-03-22T17:06:05 < catphish> i didn't try anything more complicated than a mean of 256 samples
2018-03-22T17:06:51 < catphish> overall, my software efforts felt like "garbage in garbage out", but perhaps there are better algorithms i should be trying
2018-03-22T17:08:53 < zyp> well, sure
2018-03-22T17:10:32 < catphish> perhaps something more like a weighted moving average will produce a better balance between filtering and getting results quickly
2018-03-22T17:11:52 < catphish> but at the same time, i'm hoping that some simple hardware modification might be able to remove very fast spikes better then software
2018-03-22T17:12:20 < zyp> the thing is that when you sample an analog signal, all energy present in the spectrum above the nyquist frequency gets aliased all over your sampled spectrum
2018-03-22T17:13:04 < zyp> once you've got a lot of noise all over your signal, you're not getting them separated again
2018-03-22T17:13:30 < catphish> that's true, this is why i hope some hardware low pass filtering may help more than anything i can do in software
2018-03-22T17:13:53 < zyp> option one is adding an analog low-pass filter in front of the ADC to get rid of any energy over the nyquist frequency
2018-03-22T17:14:08 < Laurenceb> I ran into these issues on early F4
2018-03-22T17:14:11 < zyp> option two is raising the sample rate and thereby raising the nyquist frequency
2018-03-22T17:14:16 < Laurenceb> used rolling median filter in the end
2018-03-22T17:14:28 < Laurenceb> as the noise distribution wasnt guassian
2018-03-22T17:14:54 < catphish> Laurenceb: interesting, thanks
2018-03-22T17:16:22 < catphish> zyp: it won't be particularly easy to add a properly designed filter at this point, unless i scrap my prototype, which i don't want to do just yet unless i have no choice, but i'm hoping something simple like a well selected bypass cap on the input pin might help to an extent
2018-03-22T17:16:23 < Laurenceb> https://github.com/Laurenceb/Chibi-Spectro/blob/master/threads/EKF_Pressure.c#L270
2018-03-22T17:16:56 < catphish> happy to combine that with different digital filters, a rolling mean / median may well be the answer

2018-03-22T17:17:08 < zyp> Laurenceb, why not something like a butterworth/chebyshev/bessel whatever?
2018-03-22T17:17:21 < Laurenceb> zyp: none of them handle non guassian noise well
2018-03-22T17:17:37 < zyp> I don't remember all my signal theory anymore, but I thought they outperformed rolling means by far
2018-03-22T17:17:46 < Laurenceb> e.g. if 1 in 100 samples are utter junk
2018-03-22T17:17:58 < Laurenceb> then you can take three samples are reject the odd one
2018-03-22T17:18:09 < Laurenceb> and you go down to 1in 10000 junk or so
2018-03-22T17:18:15 < Laurenceb> zyp: median not mean

2018-03-22T17:27:07 < catphish> my guess is that such a cap may help by offering some form of voltage buffer and low pass filter, but i don't understand the problem well enough to know what'll happen so this will just be fumbling and hoping

2018-03-22T17:30:02 < zyp> a capacitor is an impedance that decreases with increasing frequency
2018-03-22T17:31:32 < zyp> across the signal, it'll dampen higher frequencies, but the specific properties depends on the other impedances around it
2018-03-22T17:32:41 < catphish> indeed, the impedance of the source and the line will contribute, i certainly can't calculate it, but i will test some values and measure the results to begin with

2018-03-22T17:34:32 < karlp> (but you still really do want an AA filter out front in hardware.

2018-03-22T17:36:06 < Rickta59> is your chip quiet when you are doing sampling or do you have peripherals slamming digital data using DMA or whatever catphish ?
2018-03-22T17:38:30 < catphish> Rickta59: i believe i've turned off my digital IO, it didn't make a noticeable difference, i'll make sure it's off though before i do any more testing, then i can look at turning it back in later, and potentially using periods when it's idle to do my sampling

2018-03-22T17:49:36 < Rickta59> http://www.st.com/en/power-management/ld1117.html that seems to be the regulator on a nucleo
2018-03-22T17:49:37 < catphish> thanks for all the pointers
2018-03-22T17:49:48 < karlp> sample time will make a big difference,
2018-03-22T17:49:55 < karlp> clock source will make ~zero difference
2018-03-22T17:50:19 < catphish> LD39050PU33R i think
2018-03-22T17:50:53 < Rickta59> or it could be that
2018-03-22T17:51:20 < catphish> karlp: there's a couple of things i can tune, there's the clock divider, and there's the per-input sample time
2018-03-22T17:51:33 < karlp> which clock divider?
2018-03-22T17:51:44 < karlp> the adc input sampling time will make a very marked difference
2018-03-22T17:52:09 < catphish> karlp: there's a divider that sits in front of the clock input to all 3 ADCs
2018-03-22T17:52:33 < catphish> adjusting that has the effect of multiplying up the sample times of all inputs to all ADCs
2018-03-22T17:52:48 < catphish> and that certainly has a substantial impact
2018-03-22T17:53:13 < karlp> well, yes, but changing the ADC clock for the same "final" actual samplign time will make ~zero difference.
2018-03-22T17:53:30 < karlp> but of course, when the sampling time is given in "adc clock cycles" changing the adc clock of course makes a difference.
2018-03-22T17:54:05 < catphish> yep, well i won't worry about the source then, i'll just try different values of either the clock divider, or the number of cycles per sample
2018-03-22T17:54:20 < blacktronics> just set fire to everything
2018-03-22T17:54:33 < catphish> i was doing this last night, it has definite impact but it doesn't "fix" the noise
2018-03-22T17:54:52 < karlp> if you do all of this while still using a very slow samplign rate, it's still going to be garbage as zyp explained
2018-03-22T17:55:03 < karlp> yo ueither need a AA filter, or to sample faster to get away with it.
2018-03-22T17:55:14 < catphish> this does imply that my source has too much impedance for the highest sampling rates though
2018-03-22T17:55:38 < karlp> just about everything does.
2018-03-22T17:56:06 < catphish> i'll slow down the sampling until it stops improving the signal, and use it at that speed then :)
2018-03-22T17:56:19 < karlp> I'm not sure of your terminoligy.
2018-03-22T17:56:21 < catphish> at which point i'll look at other measures (digital and analog filters)
2018-03-22T17:56:35 < karlp> you want lots of samples, with quite likely a longer hold time.
2018-03-22T17:56:44 < karlp> how are you triggering the adc?
2018-03-22T17:57:04 < karlp> are you using a timer at xKHZ to get a sane/known sample rate or what?
2018-03-22T17:57:04 < catphish> manually at the moment, requesting individual sampled in a loop

2018-03-22T17:58:32 < karlp> no wonder you're having  bad time.
2018-03-22T17:58:40 < catphish> why so?

2018-03-22T17:59:14 < karlp> what is "wait for cycles" meant to be for?
2018-03-22T17:59:33 < catphish> just a rate limit
2018-03-22T18:00:36 < catphish> this is intended to be just an extremely simple example of gathering a couple of thousand samples over a couple of seconds and looking at the distribution
2018-03-22T18:00:52 < karlp> yeah, so you're still doing what zyp said will jsut give you AA issues.
2018-03-22T18:01:09 < karlp> so you're going to keep having a bad time, even if you do fiddle with the per sample sample time.
2018-03-22T18:01:48 < karlp> sample lots more, feed an IIR lowpass to get a "real" adc value, and then just pull out every 100th of that if you don't want "too many" samples for your excel based charting.
2018-03-22T18:01:49 < catphish> do you mean that each sample needs to be at an identical interval to avoid aliasing?
2018-03-22T18:02:01 < blacktronics> absolutely
2018-03-22T18:02:22 < karlp> also, you're sampling at such a low frequency, with no AA filter in front.
2018-03-22T18:04:10 < catphish> it hadn't occurred to me that sample rate would matter :(
2018-03-22T18:04:16 < blacktronics> can you oversample? cmsis dsp has a nice FIR Decimator
2018-03-22T18:04:47 < catphish> the hardware has simple add and shift oversampling
2018-03-22T18:05:12 < karlp> oversampling requires you to actually sample too :)
2018-03-22T18:05:55 < blacktronics> What hardware are you on?
2018-03-22T18:06:12 < catphish> well i can certainly make changes, either to just let the ADC run freely and pull values when i want them, or interrupt when values are available
2018-03-22T18:06:34 < catphish> i hadn't reaised this would make a difference
2018-03-22T18:06:56 < catphish> stm32l476rg on a nucleo board
2018-03-22T18:08:28 < blacktronics> you have DMA on that chip and plenty of timers
2018-03-22T18:08:37 < catphish> indeed
2018-03-22T18:09:10 < blacktronics> stream data via DMA?
2018-03-22T18:09:35 < karlp> remember that the oversamplign only oversamples what you've triggered.
2018-03-22T18:10:11 < karlp> if you can't add AA, I'd totally be using a timer to trigger sampling at a higher rate, and some digital low pass
2018-03-22T18:10:12 < catphish> the hardware oversampling just takes n samples and adds them together each time a single sample is requested

2018-03-22T18:10:44 < karlp> you're reading it differently than me then, but ok, might be :)
2018-03-22T18:11:13 < blacktronics> are you using the ADC in the chip?
2018-03-22T18:11:19 < catphish> yes
2018-03-22T18:11:42 < karlp> ok, yeah, you get new data after your N conversions. but you get extra status flags.
2018-03-22T18:11:43 < zyp> idk what this hardware oversampling is, but I don't see how that differs significantly from simply increasing sampling time
2018-03-22T18:12:11 < karlp> well, catphish's code from earlier was "oversample x now", "wait a while" "sample a few more x right now" "wait a while"
2018-03-22T18:12:19 < karlp> so yeah, still won't make any real useful difference
2018-03-22T18:12:31 < catphish> karlp: i definitely will do some digital filtering, but i want to avoid running 256 samples to get the accuracy i should get from 1 sample, and consequently totally killing my potential sample rate
2018-03-22T18:13:15 < karlp> so go put an AA filter on your hardware :)
2018-03-22T18:13:28 < catphish> karlp: yes, with hardware oversampling enabled, it was a case of "take 256 samples really fast and sum them, wait a while doing noting, repeat"
2018-03-22T18:13:48 < zyp> that's not useful
2018-03-22T18:13:59 < catphish> zyp: that was indeed my experience of it :)
2018-03-22T18:14:43 < catphish> i got much better results taking samples at longer intervals and averaging them, but that totally destroyed the rate at which i could obtain useful data
2018-03-22T18:14:54 < blacktronics> do you have The Art of Electronics?
2018-03-22T18:15:00 < Rob235> I gotta fix my retraction settings.. but the pen lifter/holder mechanism with belt tensioner looks great! https://imgur.com/a/rV1KR
2018-03-22T18:15:02 < blacktronics> it's got an excellent section on filters
2018-03-22T18:15:03 < catphish> clearly there's some compromise to be made, but i'll start by trying to make the hardware more stable
2018-03-22T18:15:29 < blacktronics> there's a nice example on AA Lowpass filters in there as well IIRC

2018-03-22T21:05:57 < sync> o0
2018-03-22T21:06:10 < sync> nobody has run eigenmode FEA on the assembly before?
2018-03-22T21:06:12 < Laurenceb> thats what I think anyway

2018-03-22T21:43:04 < stvn> Ty
2018-03-22T21:43:53 < qyx> catphish: not sure if serious or trolling
2018-03-22T21:44:10 < Steffanx> serious.
2018-03-22T21:44:33 < qyx> btw stm32 ADC is SAR type, RC "buffer" helps a lot
2018-03-22T21:44:58 < qyx> (it is actually a low pass filter)
2018-03-22T21:45:08 < stvn> Hmmmmm
2018-03-22T21:46:37 < qyx> catphish: see http://www.ti.com/lit/ml/slyp166/slyp166.pdf for example
2018-03-22T21:47:06 < catphish> qyx: honestly quite serious at this point, though obviously the construction is quite hacky
2018-03-22T21:48:32 < qyx> make your cap somewhere in the ~470pF range
2018-03-22T21:48:33 < qyx> wait
2018-03-22T21:49:31 < catphish> i'll need a resistor in there, which is a mechanical nightmare at this point
2018-03-22T21:49:52 < catphish> but yeah, the current cap is obviously stupid large, but it does solve the immediate noise problem
2018-03-22T21:50:15 < catphish> i'll have to put some more thought into a proper rc design
2018-03-22T21:50:39 < catphish> thanks for the document, couldn't find any good advice on it
2018-03-22T21:50:42 < qyx> it also makes your bandwidth unusable
2018-03-22T21:51:04 < catphish> i haven't tested the bandwidth, i assume it's rather low
2018-03-22T21:51:27 < qyx> I suppose so
2018-03-22T21:51:52 < qyx> I used a AD8605 buffer together with a 47R/220pF filter
2018-03-22T21:51:56 < catphish> though who knows, depends on the source/sink current of the source

2018-03-23T01:13:50 < karlp> how about no
2018-03-23T01:14:07 < englishman> where else does lunix install things?
2018-03-23T01:14:26 < englishman> Except in 3 letter dirs in root dir
2018-03-23T01:14:38 < karlp> where ever the installer offers you to enter?
2018-03-23T01:14:46 < karlp> like, for a user IDE, not somewhere that root owns?
2018-03-23T01:14:56 < karlp> $HOME/tools for instance?
2018-03-23T01:15:12 < englishman> don't think I've seen that before
2018-03-23T01:15:25 < karlp> well, that's just me,
2018-03-23T01:15:52 < karlp> but for a user installing atollic, keeping it's config file in /etc/atollic (for all users) is just dumb
2018-03-23T01:16:14 < karlp> and /opt for user packages is an old throwback and kinda archaic too really
2018-03-23T01:17:09 < karlp> it's not rocket science, lots of installers have worked this out for years
2018-03-23T01:18:33 < karlp> heh, the installer just hard tries "apt-get install blah" then "yum install blah" then "dnf install blah"
2018-03-23T01:18:42 < karlp> and then looks for a filename and hopes one of them worked.

2018-03-23T14:13:17 < kaa> but I will go with that maybe
2018-03-23T14:13:56 < jpa-> the cheaper you get the more bias drift it will have and that will make things difficult
2018-03-23T14:14:51 < kaa> to butt that price in perspective it costs more than cortex m0 on the board

2018-03-24T00:09:33 < Steffanx> Let me guess. Aliexpress.
2018-03-24T00:10:36 < Thorn> how did you know
2018-03-24T00:17:05 < catphish> is there a particularly easy way in an stm32 to control a pair of outputs as an inverted and non inverted pair with a dead time inserted?
2018-03-24T00:17:32 < Thorn> some timers (probably tim1 and tim2) can do that
2018-03-24T00:17:36 < catphish> it does a good job of it when using pwm, but i'm interested in doing it without pwm
2018-03-24T00:17:37 < zyp> TIM1 and TIM8
2018-03-24T00:17:58 < zyp> there's not really any way of doing it without a timer
2018-03-24T00:18:01 < Thorn> there are non-pwm pwm modes
2018-03-24T00:18:09 < Thorn> read up on those
2018-03-24T00:18:33 < catphish> i think a timer is definitely the answer, but i only saw the pwm modes
2018-03-24T00:18:47 < catphish> i'll have another look at the timers anyway
2018-03-24T00:18:49 < zyp> well, consider using only 0% and 100% duty
2018-03-24T00:18:59 < Thorn> iirc there are like 7 pwm modes and only about 2 of them actually do pwm
2018-03-24T00:19:21 < catphish> Thorn: oh yeah, i recall seeing those, i'll check
2018-03-24T00:19:52 < catphish> zyp: the problem with 0/100% pwm is waiting a whole pwm cycle for the switch, maybe thats avoidable though
2018-03-24T00:19:55 < Thorn> I'm not sure if you can do both 0% and 100% pwm in the same mode in stm32 (you can't in stm8)
2018-03-24T00:21:37 < zyp> sure you can
2018-03-24T00:21:49 < catphish> i have a half bridge and i want to turn it high when the current is too low and low when it's too high, so i need instant control, with dead time, if there's no built in way i can of course start a timer with an interrupt to do it
2018-03-24T00:22:19 < zyp> catphish, with preload disabled, it'll change immediately
2018-03-24T00:22:35 < zyp> or you could set the cycle time to something ridiculously short
2018-03-24T00:22:40 < catphish> zyp: that might just be good enough in that case :)
2018-03-24T00:23:26 < catphish> zyp: i'd have to test how the dead time interacts with changing the value mid cycle, but sounds promising
2018-03-24T00:23:32 < catphish> thanks
2018-03-24T00:23:39 < zyp> not convinced about your plan though
2018-03-24T00:23:57 < catphish> zyp: you mean current control?
2018-03-24T00:24:09 < zyp> yeah, on/off current control
2018-03-24T00:24:29 < catphish> that will require some testing, no idea how well it'll work yet
2018-03-24T00:24:45 < catphish> my current sensor seems to work well now
2018-03-24T00:24:50 < zyp> we tried something similar in some stuff I worked on
2018-03-24T00:25:11 < zyp> ended up switching to pwm control instead of on/off
2018-03-24T00:25:49 < catphish> pwm is definitely a reasonable alternative, i intend to test both
2018-03-24T00:26:12 < zyp> to be fair, they both were functional
2018-03-24T00:26:32 < zyp> but we wanted to get the switching freq higher, thus pwm
2018-03-24T00:27:04 < zyp> IIRC the control loop was running at 5 kHz
2018-03-24T00:27:12 < catphish> i don't know which will be better for me
2018-03-24T00:27:21 < zyp> then we switched to 20 kHz pwm instead
2018-03-24T00:27:32 < catphish> if i want to do "bang bang" control, i'll need a crazy fast control loop
2018-03-24T00:28:03 < zyp> control loop is still running at 5 kHz, so duty updates every four pwm cycles or so
2018-03-24T00:28:36 < catphish> yeah for on/off (bang bang) i would guess it'll need to be more like 100khz to be effective

2018-03-24T00:29:16 < zyp> which means that now you need to get accurate current samples at 100kHz too
2018-03-24T00:29:24 < catphish> yep
2018-03-24T00:29:57 < catphish> at this point i think only trial and error will tell
2018-03-24T00:30:09 < zyp> sounds like a waste of cpu IMO
2018-03-24T00:30:18 < catphish> the problem with pwm is knowing how much to change the value by on each iteration
2018-03-24T00:30:42 < catphish> if current is too low, i need to be able to guess how much to add to the pwm duty
2018-03-24T00:30:48 < zyp> just throw in a PID controller
2018-03-24T00:31:49 < zyp> idk exactly how the feedback stuff works on the stuff I were involved with, I didn't do the control algos, I just did the lowlevel stuff between them and the hardware

2018-03-24T00:32:40 < catphish> there are a few approaches i wan to try, current control with a pid, active power control with a pid, current control with bang bang switching
2018-03-24T00:33:00 < catphish> (pwm on the first two)
2018-03-24T00:33:31 < zyp> what do you mean by active power control?
2018-03-24T00:36:05 < catphish> doing a pid control on the sum on v1*i1+v2*i2+v3*i3, where v is the pwm virtual voltage and i is measured

2018-03-24T00:37:43 < catphish> this all gets tricky because one also has to advance the phase of the 3 outputs at the correct frequency
2018-03-24T00:38:30 < catphish> the rate of the advancement will be proportional to the rms voltage (pid output)
2018-03-24T00:39:28 < catphish> or a similar strategy, but just measuring the currents without regard for the voltage
2018-03-24T00:41:01 < catphish> the aim is to set the active power to a desired quantity while maintaining a frequency/voltage vario
2018-03-24T00:43:55 < catphish> the problem with PWM and a pid loop is i don't know how to convert "p" (the current error) to a voltage correction (change in pwm duty)
2018-03-24T00:45:23 < catphish> it may be good enough to assume voltage and current are proportional, i'll find out by testing
2018-03-24T00:48:29 < catphish> nah, that will never work, they're simply not proportional in real time
2018-03-24T00:50:36 < catphish> still, i'll play with it and see what works

2018-03-24T03:39:54 < Cracki> so right there you have a *time constant*

2018-03-24T13:06:50 < srk> heh, yeah, and one of the issues of odrive hw is noisy current sensing (DRV8301 + filters)
2018-03-24T13:06:53 < srk> looks cool
2018-03-24T13:07:29 < srk> what do you use for current sensing?
2018-03-24T13:07:48 < catphish> my current sensing is pretty noisy, been trying to address that the last few days, the ACS722 hall effect sensors i'm using seem good, then it seems the answer is a good filter at the ADC input
2018-03-24T13:11:59 < srk> ah, cool. I have one ACS770 but these look like a better fit for first boards
2018-03-24T13:19:39 < catphish> they have a pretty good variety, just depends how much current you want to sense i guess
2018-03-24T13:20:08 < catphish> this board is spec'd for 20A, though i'm using a 5A sensor during testing because i'm only testing at <1A
2018-03-24T13:21:35 < srk> odrive is over 100A 24V. I'm now going to try with TI's boostxl-drv8323 which is 10A
2018-03-24T13:22:46 < catphish> my design is IGBT based, so it's 600V
2018-03-24T13:22:55 < srk> oh, nice
2018-03-24T13:23:04 < catphish> the motors i'm using expect around 300v, though i'm testing at much much lower voltages, currently 12
2018-03-24T13:23:18 < catphish> 12 is the absolute minimum to make it turn :)
2018-03-24T13:23:48 < srk> with hobby bldc 24-48V is fine. for industrial even 300-400V seems to be common
2018-03-24T13:24:40 < catphish> my interest is in electric vevicles, either type would work really
2018-03-24T13:24:52 < catphish> inductrial motors are more forgiving
2018-03-24T13:24:53 < srk> going to use FoC?
2018-03-24T13:25:18 < catphish> i'm not sure yet
2018-03-24T13:25:42 < catphish> there's a LOT of math, some of which is beyond me so far
2018-03-24T13:25:49 < catphish> but i'm trying various things

2018-03-24T13:30:45 < Cracki> are there writeups about this wizardry
2018-03-24T13:32:16 < catphish> i assume anything related to permanent magnets is probably not all that useful to me
2018-03-24T13:32:37 < catphish> though certainly the transforms are the same
2018-03-24T13:32:46 < Cracki> ah, ivory/ivory tower is the magic
2018-03-24T13:32:56 < catphish> the main problem is estimating the flux

2018-03-24T13:37:47 < rene-dev> Look at how the current sensing on stmbl works. It’s cheap, easy, and low noise

2018-03-24T13:38:42 < srk> hm :)
2018-03-24T13:39:31 -!- ekaOlogik [~quassel@p54944A4E.dip0.t-ipconnect.de] has joined ##stm32
2018-03-24T13:39:33 < rene-dev> Ah
2018-03-24T13:39:50 < rene-dev> That’s not me, that’s the other stmbl guy
2018-03-24T13:40:10 < rene-dev> are you the odrive guy?
2018-03-24T13:40:12 < srk> ok :)
2018-03-24T13:40:19 < srk> no, that's Oscar
2018-03-24T13:40:27 < srk> he's not on irc afaik
2018-03-24T13:40:33 < rene-dev> Ok
2018-03-24T13:41:10 < srk> I'm mostly using odrive as a bldc devboard for canopen servo
2018-03-24T13:41:49 < catphish> rene-dev: my problem with FOC is always the integration required
2018-03-24T13:42:20 < catphish> but perhaps i'll have another look
2018-03-24T13:43:00 < catphish> right now i'l trying to work out how to use the adc with dma and interrupts
2018-03-24T13:43:27 < rene-dev> What integration? Do you have position Feedback?
2018-03-24T13:43:49 < catphish> i have no mechanical feedback at all, that's what makes it hard
2018-03-24T13:44:08 < rene-dev> ah.
2018-03-24T13:44:12 < srk> catphish: do you use all 3 ADCs to sample phases?
2018-03-24T13:44:13 < catphish> all i have is voltage and current
2018-03-24T13:44:27 < catphish> srk: i'm just using 2 right now, but physically i have 3
2018-03-24T13:44:27 < rene-dev> how do you measure current?
2018-03-24T13:44:37 < rene-dev> acs?
2018-03-24T13:44:37 < catphish> 3 x hall effect sensors
2018-03-24T13:44:42 < catphish> acs722 right now
2018-03-24T13:45:05 < catphish> https://i.imgur.com/OVwG1lV.png
2018-03-24T13:45:11 < rene-dev> use 3. it will reduce your noise a lot.
2018-03-24T13:45:40 < catphish> it's a little noisy because current is so low (200mA)
2018-03-24T13:45:59 < catphish> but it's reasonable for now
2018-03-24T13:46:43 < rene-dev> ah, you mean the flux integrator, for sensorless.
2018-03-24T13:46:49 < catphish> yes
2018-03-24T13:47:00 < catphish> that's the part i always get stuck on
2018-03-24T13:47:16 < rene-dev> I have no code for sensorless, stmbl is for servos, and servos do by definition always have feedback :)
2018-03-24T13:47:40 < rene-dev> what cpu do you use?
2018-03-24T13:47:49 < catphish> i actually made an implementation last year that did slip control using a rotary encoder, it worked pretty well, but i want it to be mechanically simpler / more reliable
2018-03-24T13:47:54 < catphish> stm32l4
2018-03-24T13:48:13 < rene-dev> hmm, l4 is probably ok
2018-03-24T13:48:34 < catphish> i don't know why l4 rather than f4, it's just what i found :)
2018-03-24T13:48:44 < catphish> i didn't research that until after i started using it
2018-03-24T13:49:35 < rene-dev> f4 has lower frequency pwm timer, noisier adc, no opamps. all not good for motor control
2018-03-24T13:50:37 < catphish> interesting, i'll stick with what i have then
2018-03-24T13:50:54 < catphish> the adcs are great and the 3 phase pwm is awesome
2018-03-24T13:51:07 < catphish> just trying to work out how to do ADC DMA
2018-03-24T13:51:17 < catphish> it's not well explained in the reference manual
2018-03-24T13:51:21 < rene-dev> it is
2018-03-24T13:51:40 < rene-dev> I dont know about the l4 tho
2018-03-24T13:52:44 < rene-dev> in stmbl the pwm timer triggers the adc, which triggers the dma, which triggers the control loop irq
2018-03-24T13:53:12 < rene-dev> you want a lot of oversampling
2018-03-24T13:53:42 < srk> that's cool, what's your sampling freq?
2018-03-24T13:53:47 < rene-dev> adc1,2 and 3,4 run in dual mode, meaning you can copy 2 adcs with 1 dma stream
2018-03-24T13:54:25 < catphish> rene-dev: that's essentially my plan, the pwm will trigger a set of ADC reads, then they're done, it'll trigger the control which will have all the data it needs to configure the next pwm loop
2018-03-24T13:54:43 < rene-dev> hmm, cant remember, its so long back :) but I think its as fast as the adc goes
2018-03-24T13:55:27 < rene-dev> I can only measure current while pwm is low, so not a lot of time, depending on angle
2018-03-24T13:55:53 < catphish> the other option is to keep the pwm and control loop totally independent, run the adc in continuous mode, trigger the control loop after every set of adc conversions and update the pwm regardless of its state
2018-03-24T13:56:24 < catphish> it is of course a bit pointless to run the control loop faster than the pwm
2018-03-24T13:56:37 < rene-dev> dont do that
2018-03-24T13:56:55 < rene-dev> keep in mind that the ccr registers are shadow registers, and are updates only on overflow
2018-03-24T13:57:03 < catphish> indeed
2018-03-24T13:57:18 < rene-dev> yes, its runnig as fast as it goes
2018-03-24T13:57:45 < catphish> the other option i want to explore is not using pwm at all, run the adc continuously (much faser), after every conversion update the outputs
2018-03-24T13:58:29 < rene-dev> thats called direct torque control. you need to ensure not to switch your mosfets too fast
2018-03-24T13:58:43 < rene-dev> https://en.wikipedia.org/wiki/Direct_torque_control
2018-03-24T13:59:16 < catphish> yep, read up loads on that, and i really can't decide if that's going to be better or worse than a pwm/foc approach
2018-03-24T13:59:35 < rene-dev> probably worst
2018-03-24T13:59:54 < rene-dev> you need to do everything a lot faster
2018-03-24T14:00:05 < rene-dev> there is no good reason to do it
2018-03-24T14:00:11 < catphish> right now, my intention is somewhat simpler, PWM and "active power control"
2018-03-24T14:00:53 < catphish> where i measure the active power at regular intervals and adjust the voltage / frequency accordingly to bring it to a desired value
2018-03-24T14:01:26 < catphish> it ends up basically being a simple v/hz control, but with the bonus of ignoring reactive current
2018-03-24T14:02:22 < catphish> really i'm quite clueless at the moment what will work and what won't, i've read quite a lot, and understood some but not all of the maths necessary
2018-03-24T14:02:50 < catphish> so i'm just experimenting, hopefully my test hardware will allow me to try several different approaches
2018-03-24T14:03:51 < rene-dev> make use of the FPU, and use physical baseunits everywhere.  that way you never need to convert anything, and you can copy and paste math :D
2018-03-24T14:05:14 < catphish> that's a good point, i'm so used to using an avr8 and avoiding all but the simplest math
2018-03-24T14:06:01 < catphish> fortunately i understand space vector very well, the only part of foc i have no idea about is the rotor flux angle estimation
2018-03-24T14:06:32 < rene-dev> thats the f3 dma config https://github.com/rene-dev/stmbl/blob/master/stm32f303/src/comps/io.c#L103-L119
2018-03-24T14:06:55 < catphish> cool, thanks, that's very helpful indeed
2018-03-24T14:07:15 < catphish> i wasn't sure about the psize and msize in particular
2018-03-24T14:07:40 < catphish> sort of assumed they were 16 bit but couldn't find out if that was correct
2018-03-24T14:07:55 < rene-dev> 32 in dual mode. 2x 12 bit
2018-03-24T14:08:13 < rene-dev> look at that svm implementation
2018-03-24T14:08:14 < rene-dev> https://github.com/rene-dev/stmbl/blob/master/shared/comps/svm.c#L54-L71
2018-03-24T14:08:59 < catphish> one really big question i have is how one gets the rotor flux angle
2018-03-24T14:09:11 < catphish> several texts on foc seem to assume you know it
2018-03-24T14:10:21 < rene-dev> the flat bottom svm saves a few switching cycles
2018-03-24T14:11:53 < rene-dev> with no feedback you need a observer. But I havent dont anything sensorless, apart from u/f for async motors...
2018-03-24T14:12:17 < catphish> in the past i've used flat bottom svm, the one that alternated between flat top and flat bottom appears to better balance load between transistors, but also requires holding the high side on for far too long
2018-03-24T14:12:34 < rene-dev> put "bemf observer" into google
2018-03-24T14:12:50 < catphish> yeah the observer / motor model stuff always seemed like black magic :(
2018-03-24T14:12:56 < rene-dev> most drivers cant do that
2018-03-24T14:13:40 < catphish> i wondered if my concept of simply monitoring the active power would be sufficient
2018-03-24T14:14:16 < catphish> but at that point it's not really FOC any more
2018-03-24T14:14:32 < rene-dev> power doesnt help
2018-03-24T14:14:34 < rene-dev> https://github.com/rene-dev/stmbl/blob/master/src/setup.c#L42
2018-03-24T14:14:47 < rene-dev> adc dma timer foo on the f4
2018-03-24T14:15:04 < catphish> cool
2018-03-24T14:15:46 < rene-dev> the comment is not corrent anymore...
2018-03-24T14:16:03 < catphish> isn't active power somewhat related to torque?
2018-03-24T14:16:13 < rene-dev> its a bit hard to get your head around all those adc modes
2018-03-24T14:16:26 < catphish> yeh, the adc does have a lot of options
2018-03-24T14:16:35 < catphish> especially for triggering
2018-03-24T14:16:50 < rene-dev> no, not at all. especially if you use flux weakening
2018-03-24T14:17:18 < catphish> that's a shame
2018-03-24T14:17:21 < rene-dev> I can dump a lot of power into a motor without generating any torque
2018-03-24T14:19:28 < rene-dev> but most important is, to use oversampling, use the dma and dual mode, and sync to pwm
2018-03-24T14:19:32 < catphish> rene-dev: that's certainly true if you weren't using the correct frequency, ultimately i suppose that's what all this is about, choosing the frequency
2018-03-24T14:19:53 < rene-dev> the f3 adc setup is really not the best...
2018-03-24T14:19:55 < catphish> i haven't even looked at dual mode, what's that for?
2018-03-24T14:20:06 < blacktronics> Dumping lots of power into a motor without generating torque is good for motors
2018-03-24T14:20:14 < blacktronics> They run best like that
2018-03-24T14:20:30 < catphish> blacktronics: i'm not sure they enjoy it that much :)
2018-03-24T14:20:35 < blacktronics> Electric motor companies hate this one simple trick
2018-03-24T14:20:39 < catphish> lol
2018-03-24T14:20:40 < rene-dev> 2 12 bit results in one 32 bit register
2018-03-24T14:20:52 < blacktronics> 12+12=32
2018-03-24T14:21:05 < catphish> rene-dev: does that mean i can measure 2 inputs without any particular need for dma?
2018-03-24T14:21:11 < rene-dev> yes :)
2018-03-24T14:21:16 < catphish> awesome
2018-03-24T14:21:24 -!- Streaker [~Streaker@unaffiliated/streaker] has joined ##stm32
2018-03-24T14:21:32 < catphish> i'll do that initially then,
2018-03-24T14:21:35 < rene-dev> yes, but its meat for dma
2018-03-24T14:21:47 < catphish> oh ok
2018-03-24T14:21:57 < rene-dev> no point without that, then you could just read 2 registers
2018-03-24T14:22:12 < catphish> there aren't 2 registers though are there?
2018-03-24T14:22:18 < catphish> there's just one, that's the problem
2018-03-24T14:22:23 < rene-dev> it saves a dma stream, and memory bandwidth
2018-03-24T14:22:35 < catphish> ADC1->DR
2018-03-24T14:22:53 < rene-dev> yes, one data register for each dma
2018-03-24T14:23:08 < blacktronics> Oh when you dual mode it actually internally writes to a single 32bit register?
2018-03-24T14:23:12 < rene-dev> (ignore injected mode for now)
2018-03-24T14:23:18 < rene-dev> yes
2018-03-24T14:23:26 < blacktronics> Oh that's good to know
2018-03-24T14:23:34 < blacktronics> Never had need for it so never looked into it
2018-03-24T14:23:43 < rene-dev> so you can serve 2 adcs with one dma stream
2018-03-24T14:23:51 < rene-dev> and always copy a word
2018-03-24T14:24:14 < catphish> oh, i need to use ADC1 and ADC2 for that
2018-03-24T14:24:18 < rene-dev> you can then even do the integration by adding the 32 bit walues
2018-03-24T14:24:27 < rene-dev> as long as you dont overflow the 16 bits ;D
2018-03-24T14:25:12 < rene-dev> pepole that thy to understand your code will hate this simple trick
2018-03-24T14:25:38 < rene-dev> yes, 1,2 and 3,4 support dual mode
2018-03-24T14:25:46 < rene-dev> dual mode also takes care of the trigger
2018-03-24T14:25:53 < catphish> my chip only has 3, with 1+2 supporting dual mode
2018-03-24T14:26:17 < catphish> if i only read 2 of my 3 current phases, i can use ADC1+2, and probably don't need DMA
2018-03-24T14:26:20 < rene-dev> you are looking at regular simultaneous trigger mode
2018-03-24T14:26:38 < rene-dev> you do, for oversampling
2018-03-24T14:26:51 < rene-dev> and always measure 3 at the same time
2018-03-24T14:27:11 < rene-dev> redues noise, all the noise will end up im gamma after the transformation
2018-03-24T14:27:23 < blacktronics> i've grown a liking to external ADC's
2018-03-24T14:27:29 < catphish> i prefer the idea of reading all 3
2018-03-24T14:27:42 < rene-dev> blacktronics: why?
2018-03-24T14:27:53 < rene-dev> depends a lot on application
2018-03-24T14:28:08 < rene-dev> also, the f4 adcs are crap
2018-03-24T14:28:15 < catphish> i'd have to use all 3 ADCs, which is a mild annoyance, because one would need to be reconfigured continuously if i wanted to do any other ADC at all
2018-03-24T14:28:18 < rene-dev> f3 ones are a lot better
2018-03-24T14:28:51 < rene-dev> you can just add other measurements to the group, or use injectes mode for other stuff
2018-03-24T14:28:56 < jpa-> catphish: injected mode is useful
2018-03-24T14:29:41 < catphish> anyway, as useful as this is, i probably need to go back to thinking about the higher level question of how to actually do my control
2018-03-24T14:30:15 < rene-dev> whats your application?
2018-03-24T14:30:47 < jpa-> catphish: dunno if i've pasted this to you already, but here is my bldc control crap   https://github.com/PetteriAimonen/ebike-controller/blob/master/src/motor_control.c
2018-03-24T14:30:54 < catphish> i can either try to make a flux angle observer, or i can try to create an excellent V/Hz algorithm that takes into account current (and hence resistive voltage drop), as well as reactive power
2018-03-24T14:32:25 < jpa-> ah yeah, you were the dude with induction motor
2018-03-24T14:32:29 < catphish> yeah
2018-03-24T14:32:31 < catphish> rene-dev: my goal is a torque control of a 3 phase induction motor, it doesn't need to be particularly accurate as my interest is in electric vehicle drive rather than industrial process
2018-03-24T14:32:56 < catphish> so many people have cool algorithms for BLDC
2018-03-24T14:33:12 < rene-dev> ah, induction motor
2018-03-24T14:33:16 < catphish> yeah

2018-03-24T17:26:46 < Cracki> would anyone have a writeup/comparison/data on the quality/noise of stm32 ADCs?
2018-03-24T17:27:20 < Cracki> and why is the f4 said to have worse adcs than the f3?
2018-03-24T17:28:32 < rene-dev> f4 adcs are noisy. my experience, and says so in the errata
2018-03-24T17:28:33 < rene-dev> http://www.st.com/content/ccc/resource/technical/document/errata_sheet/0a/98/58/84/86/b6/47/a2/DM00037591.pdf/files/DM00037591.pdf/jcr:content/translations/en.DM00037591.pdf
2018-03-24T17:28:45 < rene-dev> f3 is much better.
2018-03-24T17:29:15 < Cracki> wat why did they do that
2018-03-24T17:29:24 < rene-dev> the flash prefetch affects noise, as the flash needs a lot of power.
2018-03-24T17:29:26 < Cracki> is the f4 series older than the f3?
2018-03-24T17:29:35 < Cracki> ah so merely because f4 is more powerful?
2018-03-24T17:29:50 < rene-dev> no, because of crap design.
2018-03-24T17:29:56 < Cracki> good to know :P
2018-03-24T17:30:09 < rene-dev> section 2.1.15
2018-03-24T17:30:22 < rene-dev> This noise is always active whatever the power mode of the MCU (RUN or Sleep).
2018-03-24T17:30:22 < Cracki> could you quantify the noise you typically achieve for f4 and f3?
2018-03-24T17:30:28 < Cracki> ballpark
2018-03-24T17:30:46 < Cracki> wow noise while sleeping...
2018-03-24T17:31:30 < rene-dev> I cant put a number to it, as the f3 and f4 in my project do different things with the adc.

2018-03-24T17:32:17 < rene-dev> but at first I could not get the f3 adc to work. I was just testing, and the register always read 0. turns out, there its stable to the last bit.
2018-03-24T17:32:28 < rene-dev> on the f4 you always measure something on the adc
2018-03-24T17:32:29 < Cracki> 10% more noise, 2x more noise, what's the feeling
2018-03-24T17:32:40 < Cracki> haha stability is nice
2018-03-24T17:33:07 < Cracki> 0 meaning there was a pulldown or something, or it was beyond the lower limit?
2018-03-24T17:33:46 < rene-dev> no, pulldown
2018-03-24T17:34:24 < Cracki> hm, thanks for the info. gotta avoid the f4 then. at least f3 do come with m4f core, iirc
2018-03-24T17:34:28 < rene-dev> since then I never looked at the bits, only at the converted value.
2018-03-24T17:34:46 < rene-dev> yes, but keep in mind that even though the core is the same, they differ a lot in speed
2018-03-24T17:35:18 < rene-dev> much lower clock, and slower flash, and no prefetch or cache
2018-03-24T17:35:36 < rene-dev> its a lot less than half the speed
2018-03-24T17:35:40 < Cracki> clock of course, but instructions per clock, right?
2018-03-24T17:35:51 < Cracki> ah, slower flash can impact...
2018-03-24T17:36:22 < rene-dev> also, the f3 has a newer set of pheriperals. for example, the f3 can invert uart, and swap rx/tx pins
2018-03-24T17:36:34 < rene-dev> and has much better pheriperal interconnect, and better timers
2018-03-24T17:36:42 < Cracki> nice
2018-03-24T17:37:11 < rene-dev> they never fixed anything in the f4, to stay "compatible"
2018-03-24T17:38:22 < Cracki> got anything interesting on the F7?
2018-03-24T17:38:39 < Cracki> (except everything's faster and more and whatnot)
2018-03-24T17:40:00 < rene-dev> yes, the f7 has updates peripherals, I cant tell you about the adc. the stuff about noise is still in the errata.
2018-03-24T17:40:10 < Cracki> bad
2018-03-24T17:40:27 < rene-dev> you can get more speed on the f3 by running code from ccm
2018-03-24T17:40:54 < rene-dev> on the f4 the ccm is only on the data bus, but on the f3 its on the data and instruction bus
2018-03-24T17:41:10 < Cracki> ! that's an interesting difference
2018-03-24T17:41:11 < rene-dev> on the f7 its completley different yet again.
2018-03-24T17:42:43 < rene-dev> but the ccm is much smaller... so you could upload timing critical code to ccm and run it from there
2018-03-24T17:43:19 < Cracki> interrupt handlers too? I just read something that sounded like that's not possible

2018-03-24T17:44:43 < Cracki> AN4296 tips for using ccm ram
2018-03-24T17:45:11 < rene-dev> would either need to do some linker script magic, or compile the function as position independent
2018-03-24T17:45:17 < Cracki> indeed
2018-03-24T17:47:53 < rene-dev> maybe relocate vector table to ccm?
2018-03-24T17:48:01 < Cracki> that's what they seem to be doing

2018-03-24T18:16:30 < catphish> this is mildly interesting, voltage vs current for no load (top) vs locked rotor (bottom) https://imgur.com/a/KR0ez
2018-03-24T18:17:09 < catphish> there's a marked difference in phase
2018-03-24T18:20:19 < catphish> in this case the vast majority of the energy is being wasted in the fixed resistance of the motor :(
2018-03-24T18:29:14 < rene-dev> what do you use for plotting?
2018-03-24T18:29:42 < catphish> today i'm using the arduino IDE, it sucks, i need to find something better
2018-03-24T18:29:50 < rene-dev> use servoterm :)

2018-03-24T18:32:45 < rene-dev> various random screenshots
2018-03-24T18:32:56 < catphish> it just says "not found" :(
2018-03-24T18:33:10 < rene-dev> it uses cdc to talk to a virtual serial port
2018-03-24T18:33:26 < rene-dev> it looks for some special thing in the usb
2018-03-24T18:33:35 < catphish> i see
2018-03-24T18:33:40 < catphish> i have a regular usb serial port
2018-03-24T18:33:42 < rene-dev> https://github.com/STMBL/Servoterm-app/blob/master/Servoterm/term.js#L181
2018-03-24T18:33:49 < rene-dev> yeah, change that line
2018-03-24T18:34:00 < catphish> ah i see
2018-03-24T18:34:02 < rene-dev> but then you probably need to configure baudrate and stuff
2018-03-24T18:34:05 < catphish> clever
2018-03-24T18:34:22 < catphish> most likely
2018-03-24T18:34:26 < catphish> anyway, no rush for that
2018-03-24T18:34:42 < rene-dev> the term part is just ascii, but \n terminated strings
2018-03-24T18:34:47 < rene-dev> so you have a local comamnd history
2018-03-24T18:34:52 < catphish> cool
2018-03-24T18:35:06 < catphish> currently my code just spits out csv charts
2018-03-24T18:35:11 < rene-dev> the wave part is just 0xff followed by 8 bytes
2018-03-24T18:35:22 < rene-dev> and that wraps around
2018-03-24T18:35:32 < rene-dev> optional you can trigger by sending 0xfe
2018-03-24T18:36:01 < rene-dev> stmbl samples the data at real time, buffers them, and sends them out.
2018-03-24T18:36:11 < rene-dev> so the display is realtime
2018-03-24T18:36:12 < catphish> i'm still no closer to deciding what control strategy might work, i'll keep reading, but at least i have good (and fast) data to work with now
2018-03-24T18:37:11 < rene-dev> you need some realtime data output, normal debugging stuff doesnt work for motor control
2018-03-24T18:37:53 < catphish> yep, these realtime charts are great
2018-03-24T18:38:47 < rene-dev> there is some magic in the firmware, which allows to plot anything, or connect anything to a virtual signal generator, or connect anything to anything
2018-03-24T18:38:54 < catphish> i probably need to get dma uart working too, serial output kills my performance :)
2018-03-24T18:39:10 < rene-dev> so you can rewire all the functions at runtime
2018-03-24T18:39:12 < rene-dev> yeah, usb is much faster
2018-03-24T18:39:37 < catphish> 1Mbaud serial will be ok, but i need a non-blocking buffer
2018-03-24T18:39:58 < rene-dev> all the functions can be assigned in different oder at runtime to different tasks
2018-03-24T18:40:25 < c10ud> there's also FlexiPlot
2018-03-24T18:40:32 < c10ud> but I'm not sure it handles big baud rates
2018-03-24T18:40:36 < rene-dev> so you can rewire all the dataflow at runtime
2018-03-24T18:40:59 < c10ud> I think last time I used it for high-freq acquisition I had to hax the src code
2018-03-24T18:41:32 < catphish> i used to use this: http://live-graph.sourceforge.net/
2018-03-24T18:41:40 < catphish> but their download page is broken

2018-03-24T23:52:32 < Laurenceb_> anyone here familiar with android sensors?
2018-03-24T23:52:52 < Laurenceb_> is it possible to use accelerometers in polling or interrupt mode? Is there a switch?
2018-03-24T23:56:16 < kakimir> are you becoming an android developer?
2018-03-24T23:56:24 < Laurenceb_> hell no
2018-03-24T23:56:34 < Laurenceb_> just trying to understand what my phone was doing

2018-03-24T23:56:47 < Laurenceb_> looks like it supports polled or interrupt
2018-03-24T23:57:27 < Laurenceb_> I'm getting ~199hz data out at 200hz setting
2018-03-24T23:57:46 < Laurenceb_> so unlikely to be polled
2018-03-24T23:58:04 < Laurenceb_> huge time jitter in the timestamps
2018-03-24T23:58:14 < Laurenceb_> about 3ms rms jitter
2018-03-24T23:58:44 < Laurenceb_> sometimes a whole series of 3 or 4 samples have the same timestamp

2018-03-25T00:02:37 < Cracki> when are they stamped
2018-03-25T00:02:59 < Cracki> prolly when they enter the java domain, bunched
2018-03-25T00:05:05 < Laurenceb_> nope the stamping is right there in that code
2018-03-25T00:05:26 < Laurenceb_> ktime_get_ts(&ts);
2018-03-25T00:05:47 < Laurenceb_> I'm guessing it must be using fifo on the sensor
2018-03-25T00:06:07 < Laurenceb_> then interrupt based read that sometimes takes >5ms to be scheduled
2018-03-25T00:07:13 < kakimir> anyone want to play a game of chess?
2018-03-25T00:07:13 < Laurenceb_> dunno how that driver code runs tho

2018-03-26T01:20:24 < kakimir> can you tell me how they implement 5v tolerant pins in 3v3 mcu?
2018-03-26T01:20:41 < kakimir> they add diodes in series to clamping to VCC?
2018-03-26T01:22:47 < zyp> no, they just don't clamp it
2018-03-26T01:22:55 < kakimir> hmm
2018-03-26T01:23:03 < kakimir> HMMM!!!
2018-03-26T01:23:20 < kakimir> are you serious?
2018-03-26T01:23:34 < zyp> datasheet says current injection is not possible
2018-03-26T01:23:42 < zyp> positive current injection*
2018-03-26T01:23:49 < zyp> clamping implies current injection
2018-03-26T01:23:53 < zyp> so yes, I'm serious
2018-03-26T01:25:57 < kakimir> would you connect arduino or 5v uart adapter to such pins without anything?
2018-03-26T01:26:28 < zyp> that's the whole point of 5V tolerant pins
2018-03-26T01:26:53 < zyp> the thing you have to be aware of though is that they are only rated to Vcc+4V
2018-03-26T01:27:22 < zyp> so when Vcc is zero, you're violating the rating if you're still feeding them 5V high

2018-03-26T01:35:50 < zyp> Cracki, now you're talking about what to do if you've not got 5V tolerant inputs
2018-03-26T01:35:57 < Cracki> aye
2018-03-26T01:36:05 < zyp> again, the whole point of 5V tolerant inputs is to not have to do anything
2018-03-26T01:36:08 < Cracki> oh you guys were already having 5v-tolerant pins?
2018-03-26T01:36:14 < zyp> otherwise that would be pointless
2018-03-26T01:36:17 < Cracki> aye
2018-03-26T01:36:29 < Rob235> new tile feet almost finished for the new sorbothane hemispheres! https://i.imgur.com/CSvsYoa.png
2018-03-26T01:36:39 < Cracki> the what now?
2018-03-26T01:36:48 < zyp> most pins in the newer stm32s are FT
2018-03-26T01:36:56 < Cracki> ABS + acetone?
2018-03-26T01:37:11 < Rob235> I'll never mess with abs
2018-03-26T01:37:13 < Cracki> those black shiny things
2018-03-26T01:37:19 < Rob235> sorbothane
2018-03-26T01:37:22 < Rob235> sound dampeners
2018-03-26T01:37:39 < Rob235> bought not printed
2018-03-26T01:37:42 < Cracki> ah
2018-03-26T01:37:56 < zyp> what printer is that?
2018-03-26T01:37:59 < Rob235> anet a6
2018-03-26T01:38:09 < zyp> figures
2018-03-26T01:38:20 < zyp> looks pretty cheap
2018-03-26T01:38:28 < Rob235> yea well it was $190
2018-03-26T01:38:47 < zyp> not that I should say anything
2018-03-26T01:39:00 < zyp> probably prints better than my shit that I've spent more money on :p
2018-03-26T01:39:03 < Rob235> it prints fairly well considering
2018-03-26T01:39:40 < Rob235> still having slight trouble with PETG but pla is great, check out the silver cube: https://imgur.com/a/L2qz1
2018-03-26T01:40:08 < Rob235> at least petg is printing better than that blue cube now, that was my first petg attempt

2018-03-26T14:23:07 < dongs> the fuck is wrong wiht git
2018-03-26T14:23:10 < dongs> how do i unfcuk this
2018-03-26T14:23:43 < dongs> literally using git for anything other than single person commiting one thing at a time linearly is completely fucking impsosible
2018-03-26T14:23:47 < karlp> git pull --rebase
2018-03-26T14:23:48 < dongs> who came up with this insane shit
2018-03-26T14:23:57 < dongs> will it delete current work?
2018-03-26T14:23:57 < karlp> someone else pushed something else before you
2018-03-26T14:24:11 < dongs> no, they're failing to commit their changes.
2018-03-26T14:24:26 < karlp> someone's tried to push
2018-03-26T14:24:34 < karlp> and they are behind where they're trying to push too
2018-03-26T14:24:45 < dongs> correct, because the shit that was pushed after is trash
2018-03-26T14:24:54 < dongs> so tehy checked out old stuff and started re-workign from taht
2018-03-26T14:25:14 < karlp> if they hate other people working on the repo, they can always push -f..
2018-03-26T14:25:45 < karlp> oh, they checked it out rather than reverting it or anything.
2018-03-26T14:25:59 < dongs> correct, because none of the terminologfy makes sense
2018-03-26T14:26:12 < karlp> eh, /me is too far gone.
2018-03-26T14:26:21 < dongs> so what to do?
2018-03-26T14:26:36 < karlp> is anyone else workign on the repo that is likely to have fetched in since the bad commit went in?
2018-03-26T14:26:57 < dongs> no
2018-03-26T14:26:58 < karlp> and will _they_ have any changes that matter?
2018-03-26T14:27:01 < dongs> no
2018-03-26T14:27:05 < karlp> then just git push -f
2018-03-26T14:27:11 < dongs> using sorestree?
2018-03-26T14:27:14 < karlp> no fucking clue.
2018-03-26T14:27:24 < karlp> I'm sure they have a "force" option somewhere.
2018-03-26T14:27:31 < dongs> yes, its gray
2018-03-26T14:27:36 < karlp> hehe :)
2018-03-26T14:27:47 < karlp> can't help with that sorry.
2018-03-26T14:28:32 < karlp> still, these mm32 are fully keil supported: http://www.keil.com/dd2/mindmotion/mm32x103/
2018-03-26T14:28:33 < dongs> https://community.atlassian.com/t5/Sourcetree-questions/How-do-I-perform-a-forced-push-push-f-from-SourceTree/qaq-p/257351
2018-03-26T14:30:08 < karlp> sinowealth sm32f205 too.
2018-03-26T14:30:23 < dongs> so who stole IP from ST i wonder
2018-03-26T14:30:28 < dongs> and then shared it to all teh chinks
2018-03-26T14:30:47 < dongs> waht else can i do other than force push shite.
2018-03-26T14:30:57 < dongs> oh i guess I could save changes
2018-03-26T14:30:58 < karlp> and a whole series from here too: http://www.sonix.com.tw/
2018-03-26T14:31:04 < dongs> go back to master
2018-03-26T14:31:05 < karlp> you could save code files.
2018-03-26T14:31:08 < karlp> yeah, that will work too.
2018-03-26T14:31:09 < dongs> copy them over.
2018-03-26T14:31:11 < dongs> great.
2018-03-26T14:31:17 < dongs> source cucktroll at its finest
2018-03-26T14:31:35 < karlp> well, you can probably do the pull with merge via "throw out upstream, merge resolution via keeping mine"
2018-03-26T14:31:49 < dongs> when i figure out what that means in english I might condsider that
2018-03-26T14:32:00 < karlp> source tree should let you git pull first right?
2018-03-26T14:32:06 < dongs> sure
2018-03-26T14:32:17 < karlp> so you just pull,and when it says, "merge shit?" you just always choose your shit, not the busted upstream shit
2018-03-26T14:32:52 < dongs> i have no idea waht it did
2018-03-26T14:32:55 < dongs> it didnt ask to merge anythign
2018-03-26T14:33:10 < englishman> lol you're fucked
2018-03-26T14:33:26 < dongs> does anyone normal use git at all
2018-03-26T14:33:30 < dongs> fucking insane garbage
2018-03-26T14:33:30 < englishman> the lunix solution is to delete everything and start over. And don't fuck up next time
2018-03-26T14:33:34 < dongs> yeah
2018-03-26T14:33:36 < dongs> thats waht im about to do
2018-03-26T14:34:21 < dongs> cnpst
2018-03-26T14:34:22 < dongs> err
2018-03-26T14:34:26 < dongs> the fuck is that even

2018-03-26T14:34:30 < dongs> Completed with errors, see above.
2018-03-26T14:35:15 < jpa-> git status and then git merge --abort or whatever you have unfinished
2018-03-26T14:35:31 < karlp> they're not at the command line :)
2018-03-26T14:35:41 < jpa-> they should be :)
2018-03-26T14:35:42 < karlp> it's jsut sorestree spitting out shit
2018-03-26T14:35:52 < karlp> phone up atlassian ;)
2018-03-26T14:39:07 < dongs> error: You have not concluded your merge (MERGE_HEAD exists).

2018-03-26T14:39:10 < dongs> for fucks sake
2018-03-26T14:39:13 < dongs> so much useles garbage
2018-03-26T14:39:18 < dongs> who is the faggot who came up with these error messages?
2018-03-26T14:43:16 < dongs> oh well copied shit, reverted to head, copied shit back
2018-03-26T14:43:28 < dongs> the onyl way git works is linear changes by one person at a time
2018-03-26T14:43:44 < dongs> we might as well be using visual source safe
2018-03-26T14:48:24 < jpa-> dongs: why do you think it works even with one person?
2018-03-26T14:48:38 < dongs> yeah, sorry, i'm giving it too much credit here
2018-03-26T14:48:42 < dongs> it BARELY works wiht one person

2018-03-26T15:31:56 < jadew> main reason I didn't get back into game dev (that's how I started programming as a kid - I made games)
2018-03-26T15:32:41 < jadew> by the time I considered getting back to it, I realized everyone is just using some engine they don't understand + some graphics
2018-03-26T15:32:59 < jadew> and by everyone, I mean enough people that I didn't want to be associated with them when I would have said that I make games

2018-03-26T17:20:51 < Thorn> I ordered 15 pcbs from allpcb and received 22
2018-03-26T17:21:30 < Thorn> pcbnoway on the other hand made exactly the number ordered
2018-03-26T17:21:47 < karlp> depends how well the size fits I think.
2018-03-26T17:22:04 < karlp> elecrow has given me sometimes a few more, sometimes one more, sometimes exactly the right amount
2018-03-26T17:22:31 < dongs> more like
2018-03-26T17:22:34 < dongs> they always make extra
2018-03-26T17:22:38 < Thorn> rezonit.ru once sent me 2 panels instead of one (200 pcbs instead of 100)
2018-03-26T17:22:38 < dongs> and throw away teh oens that fail e-test
2018-03-26T17:22:59 < Thorn> (they were probably drunk)

2018-03-26T18:13:08 < tomeaton17> not only does it spike to 35V, it then takes 10 seconds to reach 5 volts
2018-03-26T18:13:29 < kakimir> it's a crime at that point tomeaton17
2018-03-26T18:13:42 < kakimir> not a bench supply, but a crime
2018-03-26T18:14:19 < tomeaton17> yeah, have emailed them and will call them tomorrow if I dont get anything. Only happens on one channel so must be a fault

2018-03-26T18:16:14 < dongs> hmm riglol is more expensive than I thought
2018-03-26T18:16:16 < tomeaton17> not sure why the current limit led is blinking with nothing connected

2018-03-26T18:17:30 < kakimir> almost a welding inverter
2018-03-26T18:17:50 < Thorn> do real time signal analyzers have the same architecture as SDRs? if so, why are they so expensive
2018-03-26T18:17:53 < kakimir> annoying thing about it - doesn't have switching for output
2018-03-26T18:18:06 < kakimir> turn it on - self tests for 10seconds and then output on
2018-03-26T18:18:18 < tomeaton17> yes, I requested the dp832 :(
2018-03-26T18:18:20 < kakimir> at whatever voltage and current
2018-03-26T18:18:28 < Thorn> or is it one half of a spectrum analyzer + sdr?
2018-03-26T18:18:33 < BrainDamage> Thorn: the sampling speed is the problem
2018-03-26T18:18:50 < dongs> is it? i thought it was the VBW
2018-03-26T18:19:04 < Thorn> don't they downconvert the signal?
2018-03-26T18:19:13 < tomeaton17> quite expensive with vat actually.
2018-03-26T18:19:26 < dongs> typical cheap sdr trash will do 30-60mhz wide channel and you can look around inside that
2018-03-26T18:19:36 < dongs> but make it go through 0-1ghz and shit becomes slow
2018-03-26T18:19:39 < BrainDamage> it's a sdr, but it's a sdr with broad as barn bandwith
2018-03-26T18:20:03 < Thorn> I remember an analyzer with a few tens MHz of real time bandwidth
2018-03-26T18:20:16 < dongs> thats cuz you paid $10 for it
2018-03-26T18:20:20 < dongs> on some secondhand auction
2018-03-26T18:20:20 < BrainDamage> that's pretty shit
2018-03-26T18:20:21 < kakimir> I plan to run next summer some raspberry pi3 at top of antenna mast with only solar power
2018-03-26T18:20:30 < BrainDamage> you can get one for hundreds
2018-03-26T18:20:36 < kakimir>  + rtl dongle
2018-03-26T18:20:37 < dongs> and it was some reject soviet shit from 1950
2018-03-26T18:20:56 < BrainDamage> you do heterodyne in software then to tune to a narrow channel and reduce the noise
2018-03-26T18:21:03 < Thorn> I just ordered a sdr (limesdr mini) with 30MHz of bw for $150 with shipping
2018-03-26T18:21:19 < dongs> you didnt otrder it
2018-03-26T18:21:22 < dongs> you dickstarted it
2018-03-26T18:21:27 < dongs> there's zero guarnatee it will deliver

2018-03-26T18:22:00 < dongs> yeah no
2018-03-26T18:22:08 < kakimir> thing with that antenna mast is that lightning hits it
2018-03-26T18:22:16 < dongs> i hope it does
2018-03-26T18:22:19 < dongs> and kills your rageberry

2018-03-26T18:24:08 < BrainDamage> unless your antenna is prominently isolated from the other features, you don't particularly care about lighting
2018-03-26T18:24:23 < BrainDamage> the rule of thumb is the rolling sphere with 100m diameter
2018-03-26T18:24:29 < kakimir> antenna is in PTC tube

2018-03-26T20:07:40 < zyp> does anyone happen to need a galvanically isolated usb to uart/i2c/spi/can/etc… adapter?
2018-03-26T20:09:04 < karlp> ..... why?
2018-03-26T20:09:50 < zyp> I need one that can do uart, can and a few gpios, and I figure that if I'm making one, might as well try to get in as much utility as possible
2018-03-26T20:10:26 < karlp> right, so yeah, you're going to make one :)
2018-03-26T20:10:45 < zyp> been thinking about it for a while, just never found the time
2018-03-26T20:10:47 < Thorn> don't forget rx-485
2018-03-26T20:10:50 < Lux> zyp: if usb1.1 is enough you could just get a cheap usb isolator
2018-03-26T20:10:56 < zyp> now I'm in the mood to dick around in altium for a while
2018-03-26T20:11:20 < karlp> 5 channel silabs isolator should do uart, spi+irq line at least.

2018-03-26T20:12:29 < zyp> MAX14850 can do i2c and spi as well if I just get the pin config on the MCU right
2018-03-26T20:13:09 < Thorn> *rs-485
2018-03-26T20:13:11 < zyp> Lux, isolator chip or a whole isolator part to put in between?

2018-03-26T20:13:26 < Lux> like that, seems to work fine
2018-03-26T20:13:32 < Lux> quick and dirty solution
2018-03-26T20:13:43 < zyp> yeah, but that's not what I want
2018-03-26T20:14:50 < Lux> but a nice custom board sounds cool too
2018-03-26T20:15:02 < zyp> my plan is to make a board with an usb-a-plug and solder points
2018-03-26T20:15:16 < zyp> then attach a cable to solder points and pot the entire thing in epoxy or something
2018-03-26T20:15:35 < zyp> to make a galvanically isolated usb to whatever cable
2018-03-26T20:16:04 < zyp> Thorn, I've thought about it, but that requires another transceiver
2018-03-26T20:16:29 < zyp> if there exists pin-compatible transceivers with the can transceiver, I could design it so that either could be populated
2018-03-26T20:16:50 < Thorn> it's probably going to be useful to far more people than CAN
2018-03-26T20:17:34 < Thorn> (perhaps unfortunately)
2018-03-26T20:18:13 < zyp> fair enough, but I need CAN, so it's getting CAN :p
2018-03-26T20:19:49 < Thorn> oh and you will need the "MAC" part of CAN implemented
2018-03-26T20:19:57 < zyp> well, duh
2018-03-26T20:20:21 < Thorn> so either a MCU or that MCP2515 or whatever shit
2018-03-26T20:20:27 < stvn> How about you polish my dome
2018-03-26T20:20:38 < zyp> yeah, my plan was stm32f042
2018-03-26T20:22:13 < zyp> hmm, at a glance, it looks like isolated can transceivers and isolated rs485 transceivers have a similar enough footprint that it might work out

2018-03-26T20:44:25 < englishman> oh qfn i was thinking qfp
2018-03-26T20:44:25 < zyp> they are all available on digikey now
2018-03-26T20:44:53 < englishman> was not a fan of the qfns due to the EP, makes them take up just as much routing area as qfp

2018-03-26T23:47:28 < kakimir> but only low voltage offsets?
2018-03-26T23:47:40 < kakimir> or planning to go mains level isolation?

2018-03-27T01:29:33 < stvn> yeah
2018-03-27T01:29:44 < BrainDamage> cpu got cheaper probably as consequence of all the security blunders

2018-03-27T01:39:05 < karlp> looks like i can save a bunch on ram at least buying in holland
2018-03-27T01:40:39 < BrainDamage> i bet it's cheap because it's ruined being underwater for long

2018-03-27T03:26:47 < Laurenceb__> its supposed to shake or something
2018-03-27T03:27:15 < Laurenceb__> I suggested that we program the shaker to give bode plots for accel sensors and nonlinearity
2018-03-27T03:27:22 < Laurenceb__> and everyone said yeah ok

2018-03-27T03:28:43 < stvn> but its fun
2018-03-27T03:29:09 < Laurenceb__> but the shakker is being too nonlinear
2018-03-27T03:29:41 < Laurenceb__> and the GERM-man guy who designed some autastic attachment bracket for the sensors is getting defensive about it...

2018-03-27T03:32:45 < Laurenceb__> I dont think they are ready for la creatura
2018-03-27T03:33:21 < ColdKeyboard> Anyone have a suggestion on how to "fuse-out" USB? Is there an IC that you can program and it would kill the D+ D- lines?
2018-03-27T03:33:48 < ColdKeyboard> Basically I want to use USB on STM32L496 and then physically disconnect the D+ and D- lines
2018-03-27T03:34:11 < ColdKeyboard> Have no idea if there is a such IC or even what it would be called?
2018-03-27T03:34:14 < Cracki> wat
2018-03-27T03:34:17 < Cracki> just hi-z the pins?
2018-03-27T03:34:18 < Laurenceb__> I dont know any non offensive memes...
2018-03-27T03:34:48 < Cracki> post the offensive shit here, maybe someone can translate into normie-compatible memes
2018-03-27T03:34:50 < dongs> ColdKeyboard: why you wanna disconenct it
2018-03-27T03:35:12 < ColdKeyboard> dongs: So people can't use it to poke around the device without opening it
2018-03-27T03:35:25 < Cracki> box cutter to the traces
2018-03-27T03:35:41 < ColdKeyboard> I saw few circuits where they use very low power fuse and burn them with mosfet
2018-03-27T03:35:57 < Cracki> just do pcb surgery
2018-03-27T03:36:00 < dongs> i dont get it

2018-03-27T03:36:03 < dongs> and why is USB involved
2018-03-27T03:36:10 < Cracki> "poke around in the device"?
2018-03-27T03:36:31 < Laurenceb__> ^ and now a slide on ur mum
2018-03-27T03:37:04  * Cracki does the gloving gesture
2018-03-27T03:37:29 < ColdKeyboard> Is there a such IC that physically disconnect data lines or fuses + mosfet is the best solution?
2018-03-27T03:37:38 < Cracki> describe the problem
2018-03-27T03:37:52 < Cracki> not your proposed solution
2018-03-27T03:37:53 < Laurenceb__> ColdKeyboard: literally why
2018-03-27T03:37:53 < dongs> ColdKeyboard: you arent explaining what the fuck you acutally want to do
2018-03-27T03:39:05 < ColdKeyboard> I have PCB in enclosure that is sealed with glue. I want to people to upload their FW and be able to kill D+ and D- lines in case they don't want other people re-loading or messing with their FW
2018-03-27T03:39:21 < Cracki> do that via bootloader
2018-03-27T03:39:31 < Cracki> if you wanna kill a port, do it physically
2018-03-27T03:39:54 < Cracki> lovingly ram a big screwdriver into the port
2018-03-27T03:40:01 < ColdKeyboard> I'll use USB bootloader, but I want to physically kill D+ and D- lines afterwards
2018-03-27T03:40:08 < dongs> nope
2018-03-27T03:40:09 < dongs> retarded.
2018-03-27T03:40:13 < dongs> write a custom bootloader
2018-03-27T03:40:21 < dongs> if someone wants your shit, they will take it apart and steal it
2018-03-27T03:40:41 < Cracki> if you really wanna physically disconnect, glue the board such that you can still poke around on the pcb
2018-03-27T03:40:43 < ColdKeyboard> If they take it apart I don't care
2018-03-27T03:40:44 < dongs> write proper bootloader, enable ROP, don't have bugs in your bootloader that allow people to leech firmware
2018-03-27T03:40:47 < Cracki> drill holes through it, I mean
2018-03-27T03:41:04 < Laurenceb__> what dongs said
2018-03-27T03:41:18 < Cracki> "fuses" can be 0 ohm resistors with very little footprint/wattage
2018-03-27T03:41:22 < ColdKeyboard> I was wondering about IC that would physically disconnect it's lines
2018-03-27T03:41:25 < Cracki> you can burn them out
2018-03-27T03:41:38 < Laurenceb__> literally why
2018-03-27T03:41:42 < ColdKeyboard> Cracki: If you look up, that's the solution that I've found in few devices
2018-03-27T03:41:54 < Laurenceb__> >ColdKeyboard: mission impossible is fiction
2018-03-27T03:41:55 < Cracki> up to where?
2018-03-27T03:42:05 < Laurenceb__> u dont need physical destruction
2018-03-27T03:42:28 < dongs> ColdKeyboard: youre doing it wrong. stop being a lazy cunt and write a bootloader
2018-03-27T03:42:35 < ColdKeyboard> Okay, I guess I have one solution for now. Just wasn't sure what would such IC be called. For example in security devices
2018-03-27T03:42:37 < Cracki> physical destruction is rather easy, just run a big fat current into the lines and make one defined component pop (0 ohm resistor)
2018-03-27T03:43:17 < Cracki> just gotta be careful where the current goes. you could kill the controller pins themselves, but that can kill more than just those
2018-03-27T03:43:46 < Laurenceb__> A U T I S M
2018-03-27T03:43:54 < Cracki> this is the internet
2018-03-27T03:44:04 < Cracki> oh hey, wrap it in tin foil!

2018-03-27T03:49:05 < Cracki> how about ionizing radiation

2018-03-27T03:50:13 < ColdKeyboard> I agree :)
2018-03-27T03:50:19 < banandana> if thers programming language with new paradigms i dont understand
2018-03-27T03:50:21 < banandana> it must be shit
2018-03-27T03:51:10 < ColdKeyboard> Hell, if I don't understand it, it must be shit or dumb and mostly it's dumb shit :D
2018-03-27T03:51:20 < ColdKeyboard> Anyhow, thanks for the input
2018-03-27T04:02:08 < dongs> its not that we don't understand it
2018-03-27T04:02:15 < dongs> its that your requirements make no sense
2018-03-27T04:02:24 < dongs> 1) user upgrades firmware via stock USB bootloader
2018-03-27T04:02:37 < dongs> 2) said user wants to prevent others (??) from poking into the firmware
2018-03-27T04:02:44 < dongs> 3) your proopsed solution is to kil USB after this
2018-03-27T04:02:56 < dongs> so what happens when user in 1) wants to chagne firmware again?
2018-03-27T04:03:00 < dongs> he neesd to buy your shit again?
2018-03-27T04:03:18 < dongs> like, im trying to think of any application where this flow of shit makes sense and I can't
2018-03-27T04:08:03 < ColdKeyboard> For example your unit is sealed and you load your bootloader and firmware over USB. Afterwards you fuse out USB and you have BLE bootloader but don't want people to use USB D+ and D- and poke aruond the pins phisically connected to the MCU. If they open the enclosure, who cares they've voided the waranty and probabbly already know what they're doing. I don't want some dumbass connecting USB to
2018-03-27T04:08:03 < ColdKeyboard> the device and trying to see if he can mess around with USB
2018-03-27T04:08:32 < dongs> then don't expose USB at all
2018-03-27T04:08:42 < dongs> make a flashing jig with bed of nails and program over uart bootlaoder
2018-03-27T04:08:48 < dongs> then epoxy that shit up inside the case
2018-03-27T04:08:49 < dongs> done
2018-03-27T04:08:58 < dongs> why the fuck is USB even involved if its not needed
2018-03-27T04:09:42 < ColdKeyboard> You're right, I should give that some more thought
2018-03-27T04:10:11 < ColdKeyboard> I was just wondering if there is a circuit that you can only change fuse from 0 to 1 and that will physically disconnect the trace
2018-03-27T04:10:22 < dongs> yes, its called analog switch
2018-03-27T04:10:51 < ColdKeyboard> Can you make it a permanently connected to one contact programatically?
2018-03-27T04:11:37 < dongs> https://assets.nexperia.com/documents/data-sheet/74HC_HCT2G66.pdf i.e. shit like this
2018-03-27T04:11:59 < dongs> i dont know, you can pulldown the enable pin (or pullup or whatever) to defaultly disable USB, then when you're flashing short a pad or something to enable it temporarily
2018-03-27T04:12:13 < dongs> again, just STOP USING USB and make proper production flash jig with pogo pins and flash over uart
2018-03-27T04:12:33 < dongs> i mean hell you can probably even make USB pogopins, its slow enough that it's not gonna matter for the time needed to flash
2018-03-27T04:12:41 < dongs> don't evne need to have a connector there
2018-03-27T04:12:55 < dongs> if someone fuckign wants USB on your board with analog disconnected switch, tehy'll just attach probes to the pins of chip directly
2018-03-27T04:12:58 < dongs> and do what they want
2018-03-27T04:13:25 < dongs> get a 1mm dril and drill a hole in teh chip wehre PA9/10 are (or wahtever USB DPDM pins are at)
2018-03-27T04:13:37 < dongs> if y ou want to 100% prevent usb bootloader
2018-03-27T04:13:50 < dongs> but as you can imagine all these "solutions" sound way more retarded than a proper one
2018-03-27T04:13:55 < dongs> which involves a custom bootlaoder and ROP
2018-03-27T04:14:06 < dongs> solves problem of people reverse engineering shit, and protects your stuff from hax/jtag/etc
2018-03-27T04:15:06 < ColdKeyboard> Awesome, I'll take a look at this analog switch as an alternative to fuse+mosfet
2018-03-27T04:15:08 < ColdKeyboard> thanks dongs!
2018-03-27T04:15:44 < dongs> this was a first random google hit there's literally thousands of them under "analog multiplexers and switches" on digikey
2018-03-27T04:17:05 < stvn> enabling innovation
2018-03-27T04:18:52 < aandrew> ColdKeyboard: what's wrong with simply not initializing the USB interface in your app after updating?
2018-03-27T04:19:23 < dongs> its not that
2018-03-27T04:19:32 < dongs> people can just short his boot0 pad
2018-03-27T04:19:37 < dongs> and plug it into usb in bootloader mode
2018-03-27T04:19:41 < aandrew> that involves opening the case
2018-03-27T04:19:42 < dongs> thats what he wants to prevent (?)
2018-03-27T04:19:43 < dongs> yeah
2018-03-27T04:19:49 < aandrew> which he already said is an ok workaround
2018-03-27T04:19:55 < dongs> donno then
2018-03-27T04:20:00 < dongs> whaetver, whole thing is retarded
2018-03-27T04:20:24 < aandrew> it does seem an odd request... don't initialize usb == pins aren't gonna do shit no matter what you do to them on the outside
2018-03-27T04:21:10 < dongs> yeah thats what I do wiht my F0 board that plugs into USB
2018-03-27T04:21:26 < dongs> i plug it in to bootloader, and after its flashed, it just uses USB plug as power
2018-03-27T04:22:52 < aandrew> yep
2018-03-27T04:23:02 < aandrew> easy peasy, japaneesey
2018-03-27T04:24:20 < dongs> but i dont give a shit if someone later gets to bootloader since code is opensores anyway
2018-03-27T04:25:45 < aandrew> that's his exact statement too
2018-03-27T04:27:53 < dongs> solution in search of a problem tehn

2018-03-27T11:20:42 < karlp> (I'm visiting holland in a couple of weeks, can pick up some things while I'm there, looks like ram and a pcie ssd will both be very noticeably cheaper there)
2018-03-27T11:21:38 < dongs> isnt there stupid VAT all over eu?
2018-03-27T11:22:18 < karlp> included int he prices I'm comparing.
2018-03-27T11:22:58 < karlp> local prices have nromally been pretty competitive, especially once you factor in shipping, but a few things I was looking at last night were _lots_ cheaper overseas, I was actualyl rather shocked.
2018-03-27T11:27:29 < zyp> how's the import rules on stuff you bring back when you're travelling home?
2018-03-27T11:28:31 < zyp> here, I can bring home stuff for up to 6k NOK VAT/duty free when I've been travelling
2018-03-27T11:30:52 < zyp> anything above I'd theoretically have to pay another 25% in fees on
2018-03-27T11:31:51 < karlp> yeah, same here,
2018-03-27T11:32:04 < zyp> in practice, they rarely check
2018-03-27T11:32:09 < karlp> yeah, same here, :)
2018-03-27T11:33:06 < zyp> not sure how many times I've walked through norwegian airport customs now, but I've only been stopped once

2018-03-27T11:40:51 < karlp> taxman is always number one in line.
2018-03-27T11:41:04 < karlp> you get a duty free allowance, but yes,

2018-03-27T11:41:41 < dongs> terrible

2018-03-27T11:44:00 < zyp> when you come from abroad at a norwegian airport, you just pick up your suitcase, then walk through either red zone or green zone at the customs gate
2018-03-27T11:44:24 < zyp> never tried red zone, at green zone you can usually just walk right through
2018-03-27T11:44:34 < zyp> sometimes there's a few customs officers glaring at you
2018-03-27T11:44:46 < dongs> right. well, in best korea/taiwan/japan they all make you fill out a little shit you hand to the 'tax free' dudes at the exit
2018-03-27T11:44:53 < dongs> and if they don't like you they can take you aside for inspection
2018-03-27T11:45:15 < zyp> yeah, I've done that a bunch of times too
2018-03-27T11:45:32 < dongs> taiwan finally got with the times, you can fill out immigration entry card online
2018-03-27T11:45:39 < dongs> that was a good waste of 5 minutes while i was waiting in line last time
2018-03-27T11:45:49 < zyp> but it's not like I ever bring anything to jp, I just buy shit there and bring home
2018-03-27T11:45:54 < dongs> oh right
2018-03-27T11:46:04 < dongs> so at return to norgay you don't have to fill out any paper?
2018-03-27T11:46:09 < zyp> correct
2018-03-27T11:46:19 < dongs> can they stop you at green zone if they think youre smuggling shit?
2018-03-27T11:46:23 < zyp> yes
2018-03-27T11:46:31 < zyp> like I said, happened to me once
2018-03-27T11:46:46 < zyp> out of, uh, a ton of flights
2018-03-27T11:47:40 < zyp> don't need to do any immigration paperwork either
2018-03-27T11:47:47 < dongs> well yeha
2018-03-27T11:48:00 < zyp> immigration officer just looks at my passport and says "have a nice day"
2018-03-27T11:48:23 < zyp> either that or I just scan passport on one of those new automated gates and walk through
2018-03-27T11:49:10 < BrainDamage> Same happens to me here, I only have to deal with more complex checks when entering a foreign country
2018-03-27T11:49:35 < zyp> you're also in schengen, aren't you?
2018-03-27T11:49:39 < BrainDamage> yup
2018-03-27T11:49:54 < dongs> when i landed in fukuoka last time from somewehre abroad they had little mobile passport/fingterprint scanners that they were rolling around the queue
2018-03-27T11:49:58 < dongs> to speed up teh process
2018-03-27T11:50:08 < dongs> but i go throug hteh re-entry gates which is liek always empty
2018-03-27T11:50:08 < zyp> nice
2018-03-27T11:50:14 < zyp> hehe
2018-03-27T11:51:11 < BrainDamage> Funny thing is that switzerland is also part of shengen but they do have customs, because they have free circulation of people, not goods.
2018-03-27T11:51:27 < zyp> same
2018-03-27T11:52:14 < zyp> schengen lets you skip the immigration checkpoint, but not the customs checkpoint
2018-03-27T11:53:30 < zyp> norwegian airports with international flights are usually divided into three zones; international outside schengen, international inside schengen, domestic
2018-03-27T11:53:58 < zyp> immigration checkpoint between the former, customs checkpoint between the latter
2018-03-27T11:54:49 < zyp> well, customs checkpoint is only for the import direction, no checks on export
2018-03-27T11:56:05 < BrainDamage> it makes perfect sense, there's hardly taxes on exported good
2018-03-27T11:56:10 < BrainDamage> goods*
2018-03-27T11:56:15 < zyp> exactly
2018-03-27T12:15:12 < karlp> fucking newegg.  add to cart, no problems, shipping calculates for delivery to newegg, click checkout, "the following items have been autoremoved from your cart as they are not elligible for delivery to the country you selected"

2018-03-27T17:23:11 < dongs> shouldn't the isolation IC be after USB socket then?
2018-03-27T17:23:37 < zyp> it's not usb that's isolated, it's all the other shit
2018-03-27T17:23:43 < dongs> ah
2018-03-27T17:24:36 < BrainDamage> as in each of the invidual busses are isolated separately?
2018-03-27T17:25:00 < zyp> I don't want to dick around with isolated power so it needs power from both sides and I want the mcu powered from the usb side
2018-03-27T17:25:21 < zyp> otherwise, just throwing a usb isolator on it would have been a cute solution too
2018-03-27T17:26:29 < zyp> BrainDamage, the buses are not all that individual

2018-03-27T17:28:33 < zyp> I've used something like that before
2018-03-27T17:28:36 < BrainDamage> zyp: so you are isolating separately the invidual busses, ofc you cannot have concurrent busses for those that pin conflict, still good enough, how much will it be?

2018-03-27T19:14:37 < dongs> found Laurenceb

2018-03-27T19:16:57 < dongs> yeah
2018-03-27T19:17:14 < Lux>  I'm also not really sure how much one can trust that dc-dc converter onboard regarding isolation voltages

2018-03-27T19:26:11 < BrainDamage> is it unidirectional?
2018-03-27T19:26:15 < Steffanx> karlp, tweakers can give you all shops. When you have an account there, you can add stuff to a "want" list and itll give how to get stuff for cheap. Where you can limited the amount of shops etc.
2018-03-27T19:26:32 < Steffanx> but not sure if you want all the hassle as a non-dutchy
2018-03-27T19:26:34 < upgrdman> englishman, 4-8 lines, unidirectional, no need for tristate
2018-03-27T19:26:39 < englishman> there are thousands of lines that do this
2018-03-27T19:26:46 < englishman> check out the ti txb series

2018-03-27T19:30:30 < dongs> 1-5mhz is nothing
2018-03-27T19:30:35 < dongs> even 74HC shit will work
2018-03-27T19:30:47 < upgrdman> dongs, 3v3 fpga talking to an ASIC that requires 5v logic
2018-03-27T19:31:02 < dongs> 74HC244 or someshit * wahtever
2018-03-27T19:31:02 < BrainDamage> yup, a dumb not gate will work fine
2018-03-27T19:31:04 < upgrdman> yes i know 5mhz is easy. just nto sure whats cheap/common
2018-03-27T19:31:09 < upgrdman> ok
2018-03-27T19:31:17 < upgrdman> ya figured it'd be 74 series
2018-03-27T19:31:19 < BrainDamage> or a buffer if you don't like inversion
2018-03-27T19:31:19 < dongs> look at the ones taht can be powered with 5V
2018-03-27T19:31:26 < dongs> but still have VIH < 3.3V
2018-03-27T19:31:29 < dongs> and you're done

2018-03-27T22:38:42 < upgrdman> on ribbon cables, does making every-other-wire GND only help with signal integrity, or does it also help it to not radiate as much EMI?
2018-03-27T22:38:48 < upgrdman> im guessing it lowers EMI but nto sure
2018-03-27T22:38:58 < jadew> both
2018-03-27T22:39:17 < upgrdman> need to do ~20MHz SPI over a 1 meter long ribbon cable
2018-03-27T22:39:32 < upgrdman> not sure if i must LVDS
2018-03-27T22:39:43 < jadew> if it has better coupling to ground, then more of the magnetic field will be between the signal and the gnd wire, so less of it in the air
2018-03-27T22:39:50 < upgrdman> ya

2018-03-27T22:49:15 < jadew> lol
2018-03-27T22:49:18 < jadew> how does that happen?
2018-03-27T22:49:30 < Cracki> wait, pins the wrong way or what?
2018-03-27T22:49:37 < upgrdman> whats wrong
2018-03-27T22:49:40 < Cracki> ^
2018-03-27T22:49:54 < Cracki> ah the pitch looks weird
2018-03-27T22:49:54 < jadew> you guys really don't see it?
2018-03-27T22:50:14 < jadew> there's a damn footprint completely out of place there
2018-03-27T22:50:18 < jadew> a big ass one
2018-03-27T22:50:18 < Cracki> point it out, my eyes aren't calipers
2018-03-27T22:50:30 < Cracki> out of place how so
2018-03-27T22:50:32 < kakimir> Teeed, learn
2018-03-27T22:50:43 < kakimir> *Thorn*
2018-03-27T22:50:46 < Cracki> that chip's footprint looks tightly packed but viable
2018-03-27T22:50:49 < jadew> oh, nvm, I'm the blind one
2018-03-27T22:50:58 < jadew> I thought the IC was another footprint
2018-03-27T22:51:01 < jadew> lol
2018-03-27T22:51:01 < Cracki> seems the pitch also does match
2018-03-27T22:51:09 < Cracki> Thorn, speak up
2018-03-27T22:51:14 < upgrdman> yes
2018-03-27T22:51:18 < upgrdman> answer us, you faggot
2018-03-27T22:51:24 < jadew> I think it's solderable
2018-03-27T22:51:32 < kakimir> Thorn, is that 7x7mm?
2018-03-27T22:51:38 < jadew> the pitch seems ok
2018-03-27T22:51:49 < Cracki> perhaps he's bitching about the big thermal pad
2018-03-27T22:51:54 < upgrdman> i've done QFN with a god damn heat gun, just fine. didn't even use a proper hot air station.
2018-03-27T22:51:57 < Cracki> which is impossible to solder with an iron
2018-03-27T22:52:01 < kakimir> Thorn, do you have solder and flux?
2018-03-27T22:52:05 < Cracki> bake it
2018-03-27T22:52:17 < kakimir> and reflow gun?
2018-03-27T22:52:24 < upgrdman> thermal pad is no problem. all my QFNs have pads
2018-03-27T22:52:26 < Cracki> get a tooth pick, paint it with paste, bake
2018-03-27T22:52:33 < upgrdman> heat gun or hot air ... problem fucking solved.
2018-03-27T22:52:44 < jadew> we don't know if that's the problem
2018-03-27T22:52:45 < Cracki> for this you definitely need a hot air gun or hot air reflow thingy
2018-03-27T22:52:51 < zyp> chinese power meter showed up, time to figure out modbus so I can talk to it
2018-03-27T22:52:51 < stvn> Put it in the oven with lunch
2018-03-27T22:52:53 < jadew> but yeah, you can do thermal pads in lots of ways
2018-03-27T22:53:00 < jadew> including with an iron, on the other side
2018-03-27T22:53:02 < Thorn> kakimir: my precision china caliper says 4.98mm
2018-03-27T22:53:04 < upgrdman> Cracki, im sure a MAKE:R would try to reflow it in a frying pan :)
2018-03-27T22:53:07 < Cracki> if this is single-sided, put it on a hotplate
2018-03-27T22:53:11 < kakimir> jeez
2018-03-27T22:53:12 < Cracki> I'm sure that works
2018-03-27T22:53:14 < jadew> zyp, what power meter?
2018-03-27T22:53:17 < kakimir> go for paste
2018-03-27T22:53:21 < Cracki> paste
2018-03-27T22:53:26 < zyp> jadew, SDM630-Modbus V2
2018-03-27T22:53:42 < kakimir> 7x7mm is solderable in same pin number
2018-03-27T22:53:54 < jadew> zyp, ah, thought it was a bench meter or something
2018-03-27T22:53:57 < kakimir> with just solder, flux and reflow gun
2018-03-27T22:54:06 < Cracki> gotta have a reflow gun :P
2018-03-27T22:54:23 < Thorn> I have a fire hazard hot air gun
2018-03-27T22:54:30 < kakimir> jeez
2018-03-27T22:54:36 < zyp> jadew, I'm not that cool
2018-03-27T22:54:39 < Cracki> get the pcb on a stand, heat from the other side
2018-03-27T22:55:19 < Cracki> Thorn, now what was the problem with that pcb and chip?
2018-03-27T22:55:29 < Thorn> Cracki: it's not soldered
2018-03-27T22:55:39 < Cracki> orly
2018-03-27T22:55:55 < Thorn> yeah
2018-03-27T22:55:55 < kakimir> Thorn, how many spare boards and chips you have?
2018-03-27T22:55:59 < zyp> what the hell
2018-03-27T22:56:04 < Thorn> 5 and 15 respectively
2018-03-27T22:56:55 < kakimir> it should be enough to make few working ones
2018-03-27T22:57:08 < zyp> I grabbed a usb cable and cut it open, what fucking genious came up with using red, white, grey, blue
2018-03-27T22:57:15 < zyp> -o
2018-03-27T22:57:43 < Thorn> better than grey, grey, grey, grey
2018-03-27T22:58:28 < kakimir> Thorn, I'd soak pads all but EP with solder + generously applied flux
2018-03-27T22:58:30 < Cracki> usb wire colors are in the standard, if I'm not mistaken
2018-03-27T22:58:54 < kakimir> make those pads stick out a little
2018-03-27T22:59:24 < kakimir> it's important not to soak EP with solder at this size of package
2018-03-27T22:59:35 < kakimir> you can not control the amount
2018-03-27T22:59:39 < Thorn> but it has to be connected
2018-03-27T22:59:48 < kakimir> there you put solder paste
2018-03-27T22:59:51 < Thorn> there is no more gnds
2018-03-27T22:59:57 < Thorn> no paste :/
2018-03-27T23:00:00 < Cracki> soak ~ apply liberally
2018-03-27T23:00:06 < Cracki> (I think?)
2018-03-27T23:00:17 < zyp> okay, I cut the A plug open, looks like blue should be green and grey should be black
2018-03-27T23:00:32 < kakimir> well it leaves in such pad really thin layer if you have hot iron and proper fluxing
2018-03-27T23:00:38 < kakimir> and even layers
2018-03-27T23:00:50 < kakimir> Thorn, get some
2018-03-27T23:01:23 < Thorn> I've been told the excess should be sucked into the vias
2018-03-27T23:01:37 < kakimir> well
2018-03-27T23:01:39 < kakimir> not always
2018-03-27T23:02:38 < kakimir> there is 3 vias that are thru and 2 blocked
2018-03-27T23:02:45 < kakimir> you might have chance
2018-03-27T23:02:51 < kakimir> *a chance
2018-03-27T23:03:43 < Cracki> the vias will suck regardless, but it allows excess to go somewhere
2018-03-27T23:04:20 < kakimir> blacked vias and small vias not so well
2018-03-27T23:04:21 < Cracki> (it wouldn't go beyond the pad and stop mask, but it would form a drop on the other side of the via)
2018-03-27T23:04:25 < kakimir> blocked
2018-03-27T23:04:26 < Cracki> heh that of course

2018-03-27T23:05:21 < kakimir> we went today with boss and bought new reflow appliance and local old school electronics shop even had solder paste

2018-03-27T23:05:35 < kakimir> white thing in the picture
2018-03-27T23:05:52 < kakimir> thermostat controlled
2018-03-27T23:06:59 < kakimir> set it to 150C and let solder paste in EP and flux on soldered pads to even out so 3x3mm chip would not drift away
2018-03-27T23:07:26 < kakimir> then gave some 5-10seconds of slow blow and it sits right down
2018-03-27T23:07:51 < kakimir> it was last chip of 5 bought
2018-03-27T23:08:36 < Cracki> aye, hotplate works like a charm
2018-03-27T23:08:44 < Cracki> perhaps check temp with an IR thermometer
2018-03-27T23:08:51 < kakimir> I did
2018-03-27T23:09:05 < kakimir> it's out of picture though
2018-03-27T23:09:17 < Cracki> heck, I had to work with a hot air station but without hotplate, it was horror
2018-03-27T23:09:36 < Cracki> happiness is a warm butt, also applies to PCBs
2018-03-27T23:09:40 < kakimir> I didn't even know hotplate was a thing until this project
2018-03-27T23:09:58 < kakimir> where it came apparent
2018-03-27T23:10:27 < Cracki> I first got to know about use of hotplates about 2 years ago. someone held an "SMD for bloody noobs" workshop
2018-03-27T23:11:00 < zyp> hmm
2018-03-27T23:11:25 < zyp> since RS485 is push-pull when active, can I get by without termination resistors?
2018-03-27T23:11:33 < zyp> I don't feel like digging out some
2018-03-27T23:11:34 < Cracki> either use them as the only heat source, or use them to keep the board hot so you don't have to fight thermodynamics as much
2018-03-27T23:11:44 < kakimir> Thorn, it's important in that size to preheat the board a little before placing the chip so that melting flux wont carry it away from the spot
2018-03-27T23:11:45 < Cracki> "get by" prolly
2018-03-27T23:11:57 < Cracki> reflections will happen.
2018-03-27T23:12:16 < Cracki> huh? first heat, then place? that's new to me
2018-03-27T23:12:34 < zyp> I'm not very concerned about reflections, I have 30cm of cable

2018-03-27T23:12:56 < Cracki> sounds tame
2018-03-27T23:13:08 < kakimir> Cracki, even small amount of gel type of flux will float the chip
2018-03-27T23:13:13 < Cracki> sure
2018-03-27T23:13:18 < kakimir> I use gel type
2018-03-27T23:13:22 < Cracki> but surface tension should keep it in place
2018-03-27T23:13:32 < Cracki> we're talking about soldering paste, right?
2018-03-27T23:13:39 < Cracki> or normal wire and tons of flux?

2018-03-27T23:16:27 < Cracki> sounds like bga reballing, only with liquid drops of solder, and not a bga
2018-03-27T23:16:33 < kakimir> eyeballing that EP solder amount

2018-03-27T23:18:36 < kakimir> Thorn, with EP you could try to apply just a drop of solder with short contact to EP
2018-03-27T23:18:56 < Thorn> yeah that is the plan
2018-03-27T23:19:04 < Thorn> no other options anyway lol
2018-03-27T23:19:07 < kakimir> so that you have kind of "spike" in there
2018-03-27T23:19:21 < kakimir> then heat it so it evens out
2018-03-27T23:19:37 < kakimir> without using iron of course
2018-03-27T23:20:23 < kakimir> and keep it soaking with flux at every turn
2018-03-27T23:21:11 < kakimir> even that spike may be excess and it's next to impossible to get it off
2018-03-27T23:26:47 < kakimir> Cracki, so can you just reflow with hot place or just preheat?
2018-03-27T23:27:00 < kakimir> *with just a hot plate
2018-03-27T23:27:05 < Cracki> the smd for bloody noobs workshop did the complete reflow on a hotplate
2018-03-27T23:27:13 < kakimir> well there
2018-03-27T23:27:23 < kakimir> Thorn, you have IR thermometer?
2018-03-27T23:27:36 < Thorn> nope :/
2018-03-27T23:27:40 < kakimir> get one
2018-03-27T23:27:46 < Cracki> we were doing the temperature curve ourselves, holding the thermometer to the hotplate and human-controlling on the power dial

2018-03-27T23:27:57 < Cracki> solder paste is like 10-20 bucks
2018-03-27T23:28:02 < Cracki> ir thermometer isn't much different
2018-03-27T23:28:26 < kakimir> well if he's going to solder it with kitchen stove
2018-03-27T23:28:27 < Cracki> you gotta be patient, not ramp power up too fast
2018-03-27T23:28:35 < Cracki> hopefully not a gas stove
2018-03-27T23:28:45 < Cracki> I go know people who reflow in a big old pizza pan
2018-03-27T23:28:58 < kakimir> Thorn, you have an electric stove?
2018-03-27T23:28:59 < Cracki> they dumped sand in and a charred aluminium plate, to spread the heat some more
2018-03-27T23:29:08 < Cracki> (the pizza pan was self-heated electrically)
2018-03-27T23:29:15 < Cracki> induction stove won't do
2018-03-27T23:29:25 < kakimir> induction stove probs kills the chip
2018-03-27T23:30:06 < Cracki> but srsly, cheap-ass hotplate, something to take the temp, you're good to go
2018-03-27T23:30:47 < Cracki> run the common temp curves, i.e. plateau at 100-150C (?) to activate the flux for a bit, then ramp up to whatever for liquidus
2018-03-27T23:31:45 < Cracki> these things work with bimetal strips to keep temperature static, so that's gonna fluctuate some.
2018-03-27T23:31:54 < Cracki> get a hotplate that has no detents for the dial. smooth rotation.
2018-03-27T23:33:30 < kakimir> you mean thermostat control
2018-03-27T23:33:44 < Cracki> yes
2018-03-27T23:34:15 < Cracki> I think that works similarly to microswitches, but with a bimetal component to represent temperature as mechanical position
2018-03-27T23:34:31 < kakimir> Thorn, and don't bother to even try with that housefire hot air gun
2018-03-27T23:35:07 < Cracki> btw, I bbqed some old mainboards for the components and connectors a while ago
2018-03-27T23:35:11 < kakimir> you have smoke coming of the board and everything around it and then your chip flies off and you will never see it again
2018-03-27T23:36:06 < Cracki> the electric hot air gun said 600 watts, but it was way too weak. an ordinary propane (?) blowtorch worked just fine, but the pcbs went a bit bubbly if you were too vigorous
2018-03-27T23:36:37 < Cracki> (we bbqed the boards from behind, the chips DID fly when we had to heat from the front)
2018-03-27T23:36:54 < kakimir> you need something to hold it level
2018-03-27T23:36:57 < kakimir> and stable
2018-03-27T23:37:24 < Cracki> vise
2018-03-27T23:37:27 < kakimir> and not actually smoke and set on fire when you do the stuff
2018-03-27T23:37:34 < karlp> zyp: no termination needed for ~most rs485 stuff really.
2018-03-27T23:37:41 < Cracki> and vertical in our case. soemone stood at the front to prod and poke the components and collect them in a pan
2018-03-27T23:37:46 < karlp> not until yo're really trying to get the speed up.
2018-03-27T23:37:58 < karlp> line biasing has been more important to me than termination hoenstly
2018-03-27T23:38:04 < kakimir> Cracki, well that is easy
2018-03-27T23:38:10 < Cracki> obvs :P
2018-03-27T23:38:38 < zyp> karlp, nice
2018-03-27T23:38:51 < Cracki> we felt like in china, sifting the loot until only solder drops and tiny passives were left
2018-03-27T23:39:08 < zyp> I'm hacking up a firmware for this other usb-rs485 thing I made to talk modbus now
2018-03-27T23:39:58 < zyp> just got to the point where I send it a bulk packet and have it thrown on the serial line, now I need to figure out something sensible to send so the meter will actually respond
2018-03-27T23:40:20 < kakimir> Cracki, then cleaning and ordering them?
2018-03-27T23:40:31 < kakimir> and selling on ebay?
2018-03-27T23:40:38 < kakimir> brand new
2018-03-27T23:41:27 < Cracki> cleaning up those with excess solder. and yes, ordering :P the fets were nice, low rdson, logic level, ...
2018-03-27T23:41:43 < Cracki> some connectors were collected too, who knows what someone might need them for
2018-03-27T23:42:03 < stvn> Okay
2018-03-27T23:42:09 < zyp> karlp, is there any standard way of pinging a modbus device?
2018-03-27T23:42:59 < Cracki> I think someone nabbed all the SPI flash chips and dumped them
2018-03-27T23:43:11 < kakimir> nice move
2018-03-27T23:43:30 < kakimir> who knows when you need one
2018-03-27T23:44:48 < Cracki> taking things apart is always an adventure.
2018-03-27T23:45:19 < Cracki> the neighboring artist got rid of his wide format ink jet. someone found the serial header for it and poked around. ThreadX rtos...
2018-03-27T23:48:21 < zyp> hey, it works
2018-03-27T23:48:37 < zyp> damn, I got the modbus polarity right at first attempt
2018-03-27T23:48:49 < karlp> zyp: absoltuely no way that's reliable.
2018-03-27T23:49:31 < karlp> they're meant to reply to requests for unknown addresses with a suitable error, but that requires knowing the slave id,
2018-03-27T23:49:51 < karlp> no-one's _meant_ to respond to broadcast, though some often will because it's helpful for discovery.
2018-03-27T23:49:59 < karlp> and some will just ignore unknowns

2018-03-27T23:57:40 < Thorn> I'm considering a dslogic clone without sdram for ~$65 (going to install sdram and change vid/pid in eeprom to make it dslogic pro)
2018-03-27T23:58:48 < Thorn> so that I can capture usb
2018-03-27T23:58:48 < karlp> whats teh upside of dslogic pro?vs say one of the 16channel 100Mhz LAs from ali?
2018-03-27T23:58:59 < Thorn> sdram
2018-03-27T23:59:09 < karlp> no, the 16ch 100Mhz all have sdram too

2018-03-28T01:09:27 < Sagiftw> Hello. HAL_IncTick is not called when using Hal_Delay within timer interrupt function. Is it a priority issue? Can it be solved?
2018-03-28T01:11:16 < zyp> Sagiftw, yes
2018-03-28T01:11:52 < zyp> the systick interrupt can't preempt your timer interrupt if they are in the same priority group
2018-03-28T01:12:09 < zyp> only interrupts in higher priority groups can preempt other timer interrupts
2018-03-28T01:13:06 < zyp> technically you can work around that by moving the systick interrupt into a higher priority group, but I advise against it
2018-03-28T01:13:27 < zyp> it's normally a bad idea to block in an ISR
2018-03-28T01:13:45 < zyp> in other words, don't call delay in the ISR
2018-03-28T01:14:13 < zyp> if you feel you have to, your code is likely badly designed, solve that instead

2018-03-28T01:45:23 < Thorn> looks like I did
2018-03-28T01:46:10 < kakimir> how
2018-03-28T01:46:14 < kakimir> pics when?
2018-03-28T01:46:47 < Thorn> I put solder onto all pads, reflowed it with hot air, went over all the pads (or so I though) with an iron
2018-03-28T01:47:25 < kakimir> can you even access those pins with iron?
2018-03-28T01:47:44 < Thorn> I could see 3.3V on gpio pins (reset state is input pull up) but it wasn't replying to swd
2018-03-28T01:49:02 < Thorn> so I cleaned the chip a little and looked at swd pads. there wasn't much solder. so I resoldered them with an iron and success
2018-03-28T01:49:09 < upgrdman> pro tip: with thermal pad QFN, get them hot, then poke them down onto the PCB with some tweezers. it helps ensure you dont have a big blob of solder causing bridges.
2018-03-28T01:49:24 < upgrdman> excess solder jizzes out the sides. remove with iron. done.
2018-03-28T01:50:59 < Thorn> ok I'll remember that
2018-03-28T01:51:04 < Cracki> so be careful that no solder is bridging pins to the thermal pad
2018-03-28T01:52:31 < Steffanx> Zyp something is wrong with your paste. Wrong url..

2018-03-28T01:57:05 < Thorn> probably a few more pins require reflow

2018-03-28T01:57:34 < kakimir> I have never ironed QFN
2018-03-28T01:57:43 < kakimir> because I use short pads
2018-03-28T01:58:10 < Thorn> this board uses almost all the pins

2018-03-28T02:28:43 < karlp> zyp: bus idle for t3.5 is the "correct" way of determining idle.
2018-03-28T02:29:19 < karlp> in practice, many libraries use protocol knowledge to count out bytes, and then choke when they get crc errors and resync eventually, and all that good stuff
2018-03-28T02:29:38 < karlp> it's not so hard on the embedded platforms, doing the t3.5 timer on linux/windows though is a different matter :)
2018-03-28T02:30:12 < karlp> oh yeah, you're going to see mixed endianness, byte swapped within words, every combination possible you can think of.
2018-03-28T02:32:19 < karlp> libmodbus 3.1 includes helpers for a lot of them, but it's a zoo.

2018-03-28T03:58:58 < jadew> The cause of the woman’s death remains a mystery, but markings on her skull reveal she had a hole drilled into her head - indicating she underwent brain surgery about a week before she died aged between 25 and 35.
2018-03-28T03:59:03 < jadew> "brain surgery"
2018-03-28T04:14:52 < dongs> Should I use Ubuntu, Kubuntu, Xubuntu, Lubuntu, or Edubuntu? Ubuntu Server Edition? What's the difference?
2018-03-28T04:14:56 < dongs> Ubuntu, Kubuntu, Xubuntu, Lubuntu, and Edubuntu are all the same Linux distro using the same base, the same software repositories, and the same release cycle. They just have different artwork, different user interfaces (in most cases), and different default programs installed.
2018-03-28T04:15:00 < dongs> haha
2018-03-28T04:15:03 < dongs> finally the truth is out
2018-03-28T04:15:03 < dongs> that the only thing different lunix distros do

2018-03-28T04:22:10 < jadew> you better believe it, how do you think they ended up deciding that they should all start shitting in the ocean instead of building even the most basic facilities

2018-03-28T04:33:27 < jadew> apparently the odds of getting food off of the street, that has been cooked in sewer oil is very high
2018-03-28T04:33:54 < branjb> do they put it in the orange chicken?
2018-03-28T04:34:40 < jadew> I don't know, I guess that if it's too cheap, they probably do

2018-03-28T05:16:36 < dongs> ROP = read out protection in STM32
2018-03-28T05:17:27 < johntramp> eg https://github.com/sashs/ropper
2018-03-28T05:17:43 < johntramp> "You can use ropper to display information about binary files in different file formats and you can search for gadgets to build rop chains for different architectures (x86/X86_64, ARM/ARM64, MIPS/MIPS64, PowerPC)."
2018-03-28T05:18:40 < englishman> in that context rop means return-oriented programming
2018-03-28T05:19:08 < englishman> https://en.wikipedia.org/wiki/Return-oriented_programming
2018-03-28T05:19:14 < johntramp> ah ok, that makes sense.

2018-03-28T14:14:41 < karlp> or usb3-B, or usb-c yes.
2018-03-28T14:14:58 < PaulFertser> They must have had some reasoning behind that. As a proper COTS cable would be cheaper than a relatively custom A-A, right?
2018-03-28T14:15:09  * karlp shrugs
2018-03-28T14:15:22 < zyp> A-A is so abused it's basically COTS anyway
2018-03-28T14:16:28 < PaulFertser> Even for USB 3.0?
2018-03-28T14:16:33 < PaulFertser> Weird
2018-03-28T14:16:55 < emeryth> actually USB 3.0 allows for this kind of cable
2018-03-28T14:16:56 < dongs> A-A usb3 definitely existrs
2018-03-28T14:17:18 < zyp> emeryth, no, it doesn't
2018-03-28T14:17:23 < dongs> all those PCie MiNeR breakouts are using A-A cables
2018-03-28T14:17:58 < karlp> huh, newtome: https://www.aliexpress.com/store/product/magnetic-wrists-wow/1801824_32702864157.html
2018-03-28T14:18:30 < dongs> https://www.aliexpress.com/item/abuse/32801867855.html
2018-03-28T14:18:36 < zyp> emeryth, as far as the standards are concerned, there's no such thing as an A-A cable
2018-03-28T14:18:48 < dongs> zyp what is the shit i linked then
2018-03-28T14:19:03 < zyp> dongs, nonstandard, obviously
2018-03-28T14:19:18 < dongs> well yes but they weoudln't use that cable if it wasnt available/cheap
2018-03-28T14:19:33 < zyp> not arguing against that
2018-03-28T14:19:47 < zyp> I'm arguing against emeryth's assertion that usb3 actually allows this
2018-03-28T14:22:04 < emeryth> zyp: there was this thing about a host-to-host debug cable?
2018-03-28T14:22:27 < karlp> other than bitcoin mining rigs, which were setup with all sortsof what can we do cheaply, the only other place i'd seen this was rockchip
2018-03-28T14:22:48 < karlp> emeryth: none of that is standard usb though
2018-03-28T14:23:44 < zyp> I don't believe the USB debug stuff is plain A to A, IIRC it's got a bridge chip in the middle, presenting a device on either side
2018-03-28T14:24:37 < emeryth> >USB 3.0 defines a new crossover cable with a Standard A plug on each end. The cable does not include VBUS, D+, or D- wires. The SuperSpeed transmit and receive wires are cross-connected to route each output to its corresponding input. The specification says the cable is intended for OS debugging and other host-to-host applications. The cable won't hurt USB 2.0 hosts because the only line that connects on
2018-03-28T14:24:39 < emeryth> these hosts is GND. USB 2.0 does not have a legal host-to-host cable except for bridge cables that contain two device controllers with a common buffer.
2018-03-28T14:24:54 < emeryth> from http://janaxelson.com/usb3faq.htm#ca_direct
2018-03-28T14:25:18 < karlp> right, the usb3 cable that doesn't include usb2 pins. those things are rare as hens teeth, and not what you're seeing on aliexpress
2018-03-28T14:25:26 < emeryth> I know
2018-03-28T14:25:40 < karlp> I wouldn't call it an A-A cable either as most of the connectors are missing.
2018-03-28T14:25:48 < karlp> but yes, you "win"
2018-03-28T14:25:52 < dongs> karlp: it could acutalyl be what we're seeing on aliexpress but i donno about missing vbus
2018-03-28T14:26:32 < jpa-> the USB3 A-A cables i've got from china have had all pins connected
2018-03-28T14:26:53 < jpa-> .. until I taped over the USB3 pins because USB3 confuses my linux :P

2018-03-28T17:02:52 < aandrew> sure, shoot
2018-03-28T17:03:18 < catphish> is there a single "correct" v/hz curve that drives a motor perfectly? and if so, can it be calculated?

2018-03-28T17:04:20 < catphish> i gave up on my FOC, and instead implemented a V/Hz control, it works really well, but i suspect i can do much better at calculating the frequency for a particular voltage
2018-03-28T17:06:40 < catphish> it works by just setting an "active power", and adjusting the voltage (and linked frequency) up and down to match the commanded power, that works great, but currently just using f = v * CONSTANT, which isn't really correct

2018-03-28T17:09:01 < catphish> maybe the question isn't so simple, i'm not sure :)
2018-03-28T17:11:40 < aandrew> catphish: yes, it's by design
2018-03-28T17:12:05 < sync> catphish: as long as you do not violate the nominal current you are fine
2018-03-28T17:12:13 < aandrew> look at the nameplate. the rated voltage, frequency and RPM gives you the V/Hz curve
2018-03-28T17:12:29 < sync> if you look at the torque/current/power graph of your motor you can work the U/f curve out
2018-03-28T17:12:42 < aandrew> it's completely linear down to 0Hz, but a drive that can actually provide 100% torque at 0Hz can be tricky
2018-03-28T17:12:58 < sync> sensorless, yes, sensored, quite easy
2018-03-28T17:13:14 < catphish> i can just do a simple nameplate ratio, which in my country is always 230v / 50Hz
2018-03-28T17:13:17 < sync> I think only HFI can actually do 0Hz acceptably
2018-03-28T17:13:34 < catphish> but, that yields quite poor torque at low voltage
2018-03-28T17:13:36 < sync> you can usually go a bit lower with the voltage
2018-03-28T17:14:03 < sync> it also depends if you are in Y or delta
2018-03-28T17:14:05 < aandrew> usually cheap drives will boost the voltage as you approach 0Hz to try to have *some* torque
2018-03-28T17:14:34 < aandrew> sync has developed a pretty nice drive, he's gonna have current (heh) and relevant answers
2018-03-28T17:14:50 < catphish> aandrew: it's that voltage boost i need
2018-03-28T17:15:14 < catphish> imo it's not linear down to 0Hz
2018-03-28T17:16:01 < aandrew> back when I was into it we'd provide a way to boost the voltage a few % as you fell down to 0Hz
2018-03-28T17:16:04 < catphish> if you take a 230V @ 50Hz motor, and apply 9.2v @ 2 Hz, you simply don't get any torque
2018-03-28T17:16:20 < catphish> that's what i need to calculate
2018-03-28T17:16:21 < aandrew> so the v/hz curve was still linear but the 0Hz point gave you liek 4% voltage boost or someshit
2018-03-28T17:16:50 < aandrew> just mind your I2T calculations and derate since your motor is likely self-cooled and not cooling effectively as you go slower
2018-03-28T17:17:03 < aandrew> alternatively use a separate cooling fan motor to keep the motor cooled
2018-03-28T17:17:36 < catphish> maybe i just need to do it like this: https://uk.mathworks.com/help/physmod/sps/powersys/ug/gs_fig_23.gif
2018-03-28T17:18:06 < catphish> ie a fixed extra at the bottom which is gradually reduced up to 0 at the top
2018-03-28T17:18:40 < catphish> yeah cooling is an issue, i haven't checked the temp of mine yet
2018-03-28T17:18:59 < sync> yes you can limit the lower voltage
2018-03-28T17:20:30 < catphish> ok, so for now i'll stick with a simple v = BOOST + hz * RATIO
2018-03-28T17:22:51 -!- c10ud [~c10ud@emesene/dictator/c10ud] has joined ##stm32
2018-03-28T17:23:17 < catphish> where RATIO is: (nameplate_voltage - boost) / nameplate_frequency
2018-03-28T17:23:40 < catphish> and BOOST is pretty much totally arbitrary according to taste
2018-03-28T17:25:24 < catphish> i hadn't realised sensorless v/hz would work so easily
2018-03-28T17:27:03 < catphish> the only thing i'm not sure about is whether to continue to do 3 phase current measurement and power calculation, or a much simpler DC current measurement, they seem to yield essentially the same result

2018-03-28T17:28:46 < aandrew> catphish: that's exactly what I said... move 0Hz's voltage from 0V to % nameplate
2018-03-28T17:28:56 < aandrew> then it's just linear
2018-03-28T17:29:04 < aandrew> you can also do two-piece or something fancier depending on your need
2018-03-28T17:29:16 < catphish> oh i see
2018-03-28T17:29:22 < catphish> yep, i'll start with that
2018-03-28T17:29:54 < catphish> the other main thing i need to do is build a power supply to boost my battery voltage to motor voltage
2018-03-28T17:30:12 < catphish> mostly just need a high power high frequency transformer
2018-03-28T17:30:35 < aandrew> I'm curious how much difference you'll see by measuring the DC bus power vs three phase AC power
2018-03-28T17:31:04 < catphish> in theory they should be identical
2018-03-28T17:31:04 < aandrew> I'm trying to think through it mentally and the only thing I can think of is that you're not protecting the individual IGBTs nor motor windings if you're not measuring each
2018-03-28T17:31:07 < aandrew> yes
2018-03-28T17:31:31 < catphish> frankly i'll almost certainly switch to measuring the DC bus
2018-03-28T17:32:25 < catphish> 1) it's 1 sensor instead of 3   2) it can be done on the low side with a shunt instead of a hall effect
2018-03-28T17:32:57 < catphish> basically a huge win in simplifying my design
2018-03-28T17:34:25 < aandrew> yes I agree
2018-03-28T17:34:31 < aandrew> what kind of power are you working on?
2018-03-28T17:34:45 < aandrew> are we talking Watts, hundreds of or kW?
2018-03-28T17:36:17 < catphish> my goals are a bit vague, my current design uses 600v 20A IGBTs
2018-03-28T17:36:59 < catphish> so with a 230V motor, probably a couple of kW
2018-03-28T17:37:13 < catphish> i'm not testing at that kind of power yet, but that's the goal
2018-03-28T17:37:53 < catphish> with IGBTs it appears to be very easy to get huge power with very little change in design
2018-03-28T17:39:50 < catphish> i need to design a power supply though, since right now i'm limiting myself to a couple of batteries, i need a way to get more voltage, and that will present challenges in terms of how much power i can get through a transformer
2018-03-28T17:41:35 < catphish> this is the third iteration of my design, the first one with any current sensing: https://i.imgur.com/A1mF0gM.jpg
2018-03-28T17:42:29 < Adluc> catphish: whats the SOIC8 IC on phase line?
2018-03-28T17:42:45 < catphish> ACS722
2018-03-28T17:43:45 < catphish> the only way i could get per-phase current sensing to work, but i don't like it that much
2018-03-28T17:45:21 < catphish> for comparison, v2 of my design, which was seriously powerful, but had no sensing of any kind: https://i.imgur.com/C7yKUw5.jpg
2018-03-28T17:46:10 < catphish> i think i'll go with DC voltage + current sensing in the next iteration
2018-03-28T17:48:58 < c10ud> nice
2018-03-28T17:49:00 < kakimir> catphish, did you fix the ADC noise?
2018-03-28T17:49:09 < kakimir> and how
2018-03-28T17:50:52 < catphish> kakimir: i did, my placing huge capacitors at the ADC input pins
2018-03-28T17:51:31 < kakimir> jesus boi.. I hoped when I saw the photo it's not what I expect it to be
2018-03-28T17:51:34 < catphish> kakimir: i genunely don't know the specification of the resulting filter, but it works
2018-03-28T17:51:57 < kakimir> you know that there is maximum capacitive load that those hall sensors can drive
2018-03-28T17:53:01 < kakimir> you need to check at least that hall sensor says that it's output is unlatchable
2018-03-28T17:53:33 < kakimir> it is RC lowpass filter essentially
2018-03-28T17:53:41 < catphish> Output Capacitance Load: Max: 10nF
2018-03-28T17:53:46 < kakimir> where you have just couple of ohms resistance
2018-03-28T17:54:13 < kakimir> so you need a big ass cap then to reach something you would do with couple of 0402 sized component
2018-03-28T17:54:26 < catphish> my design is "bad"(tm)
2018-03-28T17:54:49 < catphish> however, for reasons that i didn't care to understand, the resulting signal is very clean, and fast enough for my requirements
2018-03-28T17:55:13 < kakimir> well - it's a RC filter
2018-03-28T17:55:20 < kakimir> and it works like it should
2018-03-28T17:55:37 < kakimir> what it does it say about latching?
2018-03-28T17:55:49 < catphish> that's what i assumed, the resistsnace is of course too low and the capacitance too high for sanity
2018-03-28T17:55:53 < kakimir> is it unlatchable or short circuit proof output?
2018-03-28T17:56:06 < catphish> it says nothing about that
2018-03-28T17:56:19 < kakimir> that cap is essentially a short circuit
2018-03-28T17:56:35 < catphish> at high frequency, yes :(
2018-03-28T17:56:49 < kakimir> to what ever voltage level it might be
2018-03-28T17:56:52 < kakimir> at the moment
2018-03-28T17:57:02 < kakimir> give me that datasheet
2018-03-28T17:57:13 < catphish> it's an rc filter with no resistance but my pcb tracks
2018-03-28T17:57:30 < catphish> http://www.allegromicro.com/~/media/Files/Datasheets/ACS722-Datasheet.ashx
2018-03-28T17:58:22 < catphish> with that said, i know this is a terrible design, but i was willing to risk one of those ICs rather than scrap my whole board because it had no pads for an RC filter there
2018-03-28T17:58:38 < catphish> and, it works, so i'm happy but filled with shame

2018-03-28T18:06:31 < dongs> are you making a murder e-bike
2018-03-28T18:06:42 < kakimir> and have that ground current thing also that trips when you have current from line or neutral to ground
2018-03-28T18:06:50 < catphish> maybe an e-go-kart, something of that nature
2018-03-28T18:06:57 < catphish> mains is no good for this :(
2018-03-28T18:07:09 < kakimir> you know how big and expensive that step up will be catphish?
2018-03-28T18:07:14 < catphish> nope :(
2018-03-28T18:07:16 < kakimir> you need another board
2018-03-28T18:07:18 < kakimir> big one
2018-03-28T18:07:22 < catphish> i really haven't researched this much yet
2018-03-28T18:07:26 < kakimir> with lot of beefy stuff

2018-03-28T18:07:50 < catphish> i was hoping just to use a transformer, but no idea how big it has to be
2018-03-28T18:07:55 < dongs> what he probably could do is dc>ac then step-up transfomer
2018-03-28T18:08:02 < catphish> dongs: that was the plan
2018-03-28T18:08:04 < dongs> but at the current he wants the shit at everything is gonna be huge
2018-03-28T18:08:16 < catphish> high frequency means less iron, rght
2018-03-28T18:08:24 < catphish> but still some big windings
2018-03-28T18:08:39 < dongs> just google 120V/220V stepup or stepdown tarnsofmer
2018-03-28T18:08:45 < dongs> that they sell for appliances etc on amazon
2018-03-28T18:08:48 < dongs> shit's like 10kg
2018-03-28T18:08:49 < catphish> those are 50hz though
2018-03-28T18:08:56 < catphish> i don't need anywhere near that much core
2018-03-28T18:09:21 < kakimir> I would just have that 300V battery pack without even thinking about it
2018-03-28T18:09:42 < catphish> one *can* buy a 300v battery
2018-03-28T18:09:49 < kakimir> build
2018-03-28T18:09:59 < dongs> catphish: use nissan leaf packs
2018-03-28T18:10:01 < catphish> but i kinda thought i migh stay alive longer by keeping the HV inside a box
2018-03-28T18:10:09 < dongs> cheap and good
2018-03-28T18:10:26 < kakimir> well - you will have it still
2018-03-28T18:10:32 < catphish> yeah i recall looking at those, and old prius packs
2018-03-28T18:11:36 < kakimir> I think likelyhood of you dying when doing this transformer thing is far greater imo
2018-03-28T18:12:19 < dongs> i got probly around 60 leaf packs
2018-03-28T18:12:22 < kakimir> instead of battery pack with proper safe design
2018-03-28T18:12:23 < dongs> need to monetize that shit one of these days
2018-03-28T18:12:37 < dongs> thats 400V
2018-03-28T18:12:51 < kakimir> could do for 230V motor
2018-03-28T18:13:13 < catphish> interestingly the prius has a boost module
2018-03-28T18:14:18 < kakimir> maybe the battery pack is too small to get proper high voltage out of them
2018-03-28T18:14:44 < catphish> http://nkirkby.net/wp-content/uploads/inside_schema.png
2018-03-28T18:14:49 < catphish> like that apparantly
2018-03-28T18:14:54 < kakimir> you need to have some paraller cells and shiet to minimize balancing and to even out cell differences
2018-03-28T18:15:26 < aandrew> catphish: use LEMs for current sense on each phase if you want it
2018-03-28T18:15:39 < kakimir> just a series of cells is defined by it's weakest link
2018-03-28T18:15:47 < sync> catphish: use 3x lowside shunt
2018-03-28T18:15:55 < aandrew> dongs: you've got a bunch of Leaf battery packs? why?
2018-03-28T18:15:56 < kakimir> I'd do that too
2018-03-28T18:16:01 < kakimir> lowside shunts
2018-03-28T18:16:04 < kakimir> amps
2018-03-28T18:16:19 < kakimir> amps -> RC -> ADC
2018-03-28T18:16:30 < catphish> sync: i probably only need one lowside shunt, no point multiplying the error
2018-03-28T18:16:40 < sync> no, you need three
2018-03-28T18:16:41 < dongs> aandrew: used some in my e-fourwheleer, the rest will eventually use for something
2018-03-28T18:16:44 < sync> or at least two
2018-03-28T18:16:51 < dongs> i got 2 leaf batt modules (entier thing) for cheap
2018-03-28T18:16:57 < kakimir> how much?
2018-03-28T18:17:12 < kakimir> how much is dongs cheap?
2018-03-28T18:17:14 < dongs> so like 45?ish kW worth of batts
2018-03-28T18:17:14 < catphish> sync: any particular reason, i came to the conclusion having 3 was redundant, because the power in the 3 phase is identical to the DC power
2018-03-28T18:17:40 < catphish> dongs: how much do they cost, and what specs?

2018-03-28T18:17:57 < sync> because you always have two phases conducting
2018-03-28T18:18:05 < sync> and you cannot determine which current goes through which
2018-03-28T18:18:29 < sync> and if you do flat bottom PWM you ideally have three sensors as one is always zero
2018-03-28T18:18:39 < catphish> sync: i don't think i actually care which current goes through which any more
2018-03-28T18:18:40 < dongs> catphish: you can probly get them for cheap from wreckers. https://electrek.files.wordpress.com/2016/08/nissan_leaf_battery_pack_dc_03_2011_1629-e1470415227690.jpg?quality=82&w=1500#038;strip=all&w=1500
2018-03-28T18:18:42 < sync> and you can null out errors that way
2018-03-28T18:18:46 < sync> you do
2018-03-28T18:18:50 < dongs> iirc inside is 48? cells 2S2P
2018-03-28T18:18:59 < sync> if you want to do SVM
2018-03-28T18:19:10 < sync> or even if you don't, regulated current is the way to go
2018-03-28T18:19:28 < catphish> sync: i'm doing svm now, but i'm ignoring the per phase currents and just working on the total power
2018-03-28T18:19:41 < sync> why?
2018-03-28T18:19:46 < Sagiftw> Hello. I'm using ADC on DMA mode to sample continiously. I'm trying to useHAL_ADC_Stop_DMA to stop the DMA and HAL_ADC_Start to restart it, but the latter doesn't work. Any ideas?
2018-03-28T18:19:56 < catphish> because i couldn't fidnd any use for the individual phase currents
2018-03-28T18:20:21 < sync> you need those to control torque
2018-03-28T18:20:24 < catphish> i just generate a sine wave using svm and then measure the total power
2018-03-28T18:20:59 < catphish> previously i had planned to do vector / torque control, but basically gave up
2018-03-28T18:21:09 < catphish> so i'm now just doing power regulation
2018-03-28T18:21:18 < catphish> which seems to have the desired result
2018-03-28T18:21:52 < catphish> as far as i can tell, power is pretty much proportional to torque if you get the v/hz curve right
2018-03-28T18:22:07 < catphish> "sensorless FOC is hard" :(
2018-03-28T18:22:40 < dongs> oh sensorless what
2018-03-28T18:22:46 < dongs> why teh fuck would you have a sensorless motor in ebike
2018-03-28T18:23:01 < dongs> you need it sensored for low rpm, there';s no way to do it right without
2018-03-28T18:23:04 < dongs> you'll just burn shit
2018-03-28T18:23:21 < aandrew> dongs: do you do anything special for storage? I have some real concerns about having so much energy in a small space just waiting to start a serious fire
2018-03-28T18:23:38 < dongs> aandrew: you mean... like when my server room caught on fire from overcharging lipos?
2018-03-28T18:23:49 < aandrew> yeah just like that
2018-03-28T18:23:58 < catphish> dongs: mechanical simplicity, you can't really make a fire if you do power control, there shouldn't be more power than the motor can handle
2018-03-28T18:24:06 < aandrew> I think I need to build a metal/concrete box to store that shit in if I get into it
2018-03-28T18:24:09 < BrainDamage> catphish: whorever draw that prius schematic misunderstood one thing, the inductor and the cap are integral part of the boost converte
2018-03-28T18:24:49 < catphish> BrainDamage: i wasn't sure about that, since those are huge components, i wondered if they were physically separate / plugged in
2018-03-28T18:25:07 < sync> look at a prius inverter teardown
2018-03-28T18:25:11 < sync> they are very close
2018-03-28T18:25:12 < catphish> BrainDamage: anyway, i know how it works, but i don't think i'm necessarily up to the task of building it right :)
2018-03-28T18:25:31 < catphish> thought a transformer design might be easier
2018-03-28T18:25:37 < catphish> but weight might suck
2018-03-28T18:26:09 < BrainDamage> they have to be, if they weren't the switches would literally explode
2018-03-28T18:26:10 < dongs> catphish: ? if you are sending current through a shorted phase of the motor and not commutating = smoke
2018-03-28T18:26:17 < aandrew> dongs: not true, sensorless vector was used for hundreds of kW industrial motors for YEARS
2018-03-28T18:26:37 < aandrew> you always have your basic I2T motor model running for electronic overcurrent protection
2018-03-28T18:26:42 < dongs> aandrew: yes but waht RPM do they run at and how much torque do they need close to 0RPM
2018-03-28T18:26:47 < catphish> dongs: shorted phase?
2018-03-28T18:27:07 < aandrew> dongs: yes, 0RPM is a problem, but most don't run under 100rpm or so at worst case
2018-03-28T18:27:14 < dongs> aandrew: thats the point
2018-03-28T18:27:25 < dongs> and on e-bike/buggy/whatever you need high torque at 0 to low rpm
2018-03-28T18:27:25 < catphish> all phases have some ohmic resistance, enough that i can run my code at DC and it can still control the power
2018-03-28T18:27:29 < aandrew> the worst lie ever told was "buy our drives to reduce the speed of your motors by 15% to save energy"
2018-03-28T18:27:31 < dongs> no way to do it without halls
2018-03-28T18:27:53 < aandrew> dongs: we would use encoders but yeah same idea
2018-03-28T18:28:07 < catphish> i couldn't get sensorless vector to work at all :(
2018-03-28T18:28:23 < catphish> but what does seem to work well is v/hz with power control
2018-03-28T18:29:17 < catphish> i modulate 3 sine waves, measure current, increase or decrease the voltage to bring power to the desired level

2018-03-28T18:30:26 < aandrew> SVM requires a good motor model
2018-03-28T18:30:42 < catphish> maybe it depends on what you mean by SVM
2018-03-28T18:31:13 < Sagiftw> Hi, I'm using ADC on DMA mode to sample continuously. I'm trying to use HAL_ADC_Stop_DMA to stop the DMA and HAL_ADC_Start_DMA to restart it, but the latter doesn't work. Any ideas?
2018-03-28T18:31:16 < aandrew> it's always a good idea to measure the IGBT saturation and if you see your IGBTs coming out of saturation when you dont' expect them to, shut the whole thing down immediately
2018-03-28T18:31:18 < catphish> i use SVM just to generate a 3 phase sine wave, like this: http://www.spacevector.net/images/3ph_wav_4_70pct.jpg
2018-03-28T18:31:32 < catphish> then i just vary its voltage and frequency
2018-03-28T18:31:34 < dongs> hey Sagiftw we saw your message last time. but nobody here uses hal. my suggestion: look at hal sores and see what those functions actually do. and see why they arent wroking
2018-03-28T18:32:03 < dongs> bedtime
2018-03-28T18:32:17 < Sagiftw> dongs: What are you using then?
2018-03-28T18:32:23 < catphish> it's not space vector in the FOC sense
2018-03-28T18:32:37 < catphish> but the output looks much the same
2018-03-28T18:34:29 < catphish> i could get a leaf battery i guess :)
2018-03-28T18:37:35 < sync> catphish: one trick for moar power is to use flat bottom pwm
2018-03-28T18:38:53 < catphish> sync: that's essentially what i'm calling SVM, like this: http://www.spacevector.net/images/3ph_wav_4_70pct.jpg
2018-03-28T18:38:56 < catphish> that's what i output
2018-03-28T18:39:45 < catphish> i started with this: https://upload.wikimedia.org/wikipedia/commons/5/5a/Space_Vector_Modulation.gif
2018-03-28T18:40:20 < catphish> and when you generate a full circle, the output looks like the waveform above (flat bottom sine, or whatever you may call it)
2018-03-28T18:41:41 < catphish> in each sector of the circle, one of the 3 phases is always zero
2018-03-28T18:46:18 < sync> yes, but now plot your modulation index
2018-03-28T18:46:37 < catphish> my what?
2018-03-28T18:47:10  * catphish googles
2018-03-28T18:51:38 < englishman> ffffuuuu no GHR-02V-S in stock anywhere
2018-03-28T18:52:44 < catphish> sync: thanks for the pointers, i'm pretty comfortable with my plans for now i think, apart from how i will generate my DC supply
2018-03-28T18:53:43 < catphish> i also have no way to run the motor at more than rated frequency in my scheme, which is a slight annoyance
2018-03-28T18:53:51 < catphish> but hopefully i can work something out for that
2018-03-28T19:01:02 < sync> well, that depends on how you connect your motor
2018-03-28T19:04:34 < catphish> does it?

2018-03-28T19:11:16 < catphish> this is my strategy at the moment: https://github.com/catphish/stm32_vfd/blob/master/main.c#L93 it's extremely simple, but surprisingly effective, it'll be even simpler when i remove the 3 phase sensors, its ability to keep power at the set level is actually better than i expected
2018-03-28T19:11:48 < catphish> the main remaining question is where i get the supply voltage from, maybe i'll take up the simpler suggestion of getting a huge battery

2018-03-28T19:30:35 < aandrew> we used to do single phase in three phase out all the time with a simple voltage doubler front end
2018-03-28T19:31:01 < aandrew> actually not even that... that was for 115V in, 230V out
2018-03-28T19:31:30 < aandrew> for single phase in, 3 phase out we just derated the drive to 67% to account for the incoming line current and increased ripple voltage in the caps
2018-03-28T19:31:34 < aandrew> worked fine

2018-03-28T22:27:32 < jpa-> upgrdman: considering that the compiler doesn't usually know the size of the cache lines, you'll have to define the cache_line_size yourself
2018-03-28T22:27:48 < upgrdman> hmm
2018-03-28T22:27:53 < upgrdman> ya it would be arch-specific
2018-03-28T22:27:59 < upgrdman> couldnt it come from a compile flag
2018-03-28T22:28:20 < upgrdman> e.g. dont all avx2-compatible cpus have the same cache line size?
2018-03-28T22:28:49 < jpa-> what are you trying to do anyway?
2018-03-28T22:29:06 < upgrdman> nothing atm. just think about the "false sharing" rpoblem
2018-03-28T22:29:28 < upgrdman> e.g. ensure threads with separate data and not thrashing the cache by accident
2018-03-28T22:35:07 < Ultrasauce> sounds like premature optimization to me
2018-03-28T22:35:42 < zyp> hmm
2018-03-28T22:35:58 < zyp> does M7 have both I-cache and D-cache?
2018-03-28T22:40:23 < zyp> also, can even threads trash each other's cache on a singlecore system?
2018-03-28T22:42:19 < karlp> upgrdman: you can even use attributes to do separate functoins for different archs ;)
2018-03-28T22:43:04 < zyp> karlp, https://paste.jvnv.net/view/UPvrM
2018-03-28T22:43:05 < upgrdman> ya
2018-03-28T22:43:15 < zyp> looks like I got current gain right, but voltage gain is off
2018-03-28T22:43:20 < upgrdman> zyp, that isnt re: embedded. just thinking about computing in general
2018-03-28T22:44:16 < karlp> or the eastron is :)
2018-03-28T22:44:38 < karlp> I had three meters out the other day, 2 showed exactly 230, third showed like 232.
2018-03-28T22:44:57 < zyp> well, multimeter shows something in between, but that's total shit anyway
2018-03-28T22:44:58 < karlp> bright side, the ones with the mid stamp were the "right" ones at least .)
2018-03-28T22:45:27 < karlp> was doing active energy testing per iec 61557-12 today, god that sort of shit is tedious :)

2018-03-28T22:45:37 < zyp> haha
2018-03-28T22:46:20 < karlp> fortunately, it's all passing so far :)
2018-03-28T23:04:00 < catphish> if i compile my stm32 code with "-mfloat-abi=hard -mfpu=fpv4-sp-d16" it doesn't seem to run, is that not correct, or am i missing something else?
2018-03-28T23:05:15 < zyp> which mcu is this?
2018-03-28T23:05:34 < Rob235> is it okay to just hotglue wires to a circuit board? after soldering them of course, just to hold them down so that they don't get pulled off
2018-03-28T23:05:39 < zyp> and what flags do you build with when it works?
2018-03-28T23:07:38 < catphish> zyp: STM32L476RG
2018-03-28T23:07:57 < catphish> full working flags: "-Wall -mcpu=cortex-m4 -mthumb -I$REPOROOT/Drivers/CMSIS/Device/ST/STM32L4xx/Include -I$REPOROOT/Drivers/CMSIS/Include -DSTM32L4xx -O2"
2018-03-28T23:08:20 < catphish> when i add "-mfloat-abi=hard -mfpu=fpv4-sp-d16" it uses hardware fpu instructions, but doesn't run
2018-03-28T23:08:49 < zyp> my guess is that it hardfaults because you haven't turned on the fpu before issuing fp instructions
2018-03-28T23:09:38 < catphish> zyp: i was contemplating that too, i use generated init code, i guess i need to add code to turn on the fpu early on, i'll check
2018-03-28T23:10:10 < karlp> catphish: did you pass those flags to the linker too?
2018-03-28T23:10:20 < zyp> I'm not familiar with whatever code you're using, but fpu is turned on by setting a couple of bits in the CPAC register
2018-03-28T23:10:29 < catphish> karlp: yes
2018-03-28T23:10:39 < zyp> your lib probably has a helper function or something for that
2018-03-28T23:11:26 < catphish> http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0553a/BEHBJHIG.html
2018-03-28T23:11:33 < catphish> if not, i can do that
2018-03-28T23:13:11 < catphish> all the init code (st tool generated it for me) is assembly already
2018-03-28T23:18:59 < catphish> just found this boilerplate code, this might work: SCB->CPACR |= ((3UL << 10*2) | (3UL << 11*2));
2018-03-28T23:23:29 < catphish> zyp: this works: SCB->CPACR |= 0xf00000;
2018-03-28T23:23:30 < catphish> thanks!
2018-03-28T23:23:55 < catphish> Rob235: i don't see why not, if it works

2018-03-29T05:14:29 < Thorn> I mean the actual sensor
2018-03-29T05:14:30 < Cracki> oh, LM393, not 303
2018-03-29T05:14:33 < Cracki> yes, told ya
2018-03-29T05:14:34 < dongs> yeah hes talking about the round thing
2018-03-29T05:14:39 < Thorn> the white round shit
2018-03-29T05:14:42 < dongs> i.e. the actual sensor
2018-03-29T05:14:46 < Cracki> oh
2018-03-29T05:14:54 < Cracki> hm, figured it was some mems stuff
2018-03-29T05:15:02 < dongs> throgh-hole mems?
2018-03-29T05:15:02 < dongs> fuck off
2018-03-29T05:15:04 < Cracki> the original page has schematics and shit
2018-03-29T05:15:23 < dongs> lol @ SENSOR
2018-03-29T05:15:25 < dongs> in schematic
2018-03-29T05:15:45 < Cracki> misread the search results... "LSM303" https://www.adafruit.com/product/1120

2018-03-29T05:16:37 < Cracki> prolly something like a metal link that moves around upon motion and makes contact ¯\_(ツ)_/¯
2018-03-29T05:16:46 < dongs> yeah or mercury switch
2018-03-29T05:17:00 < Cracki> tasty
2018-03-29T05:17:40 < Thorn> ordered it just to read the markings lol
2018-03-29T05:17:50 < dongs> so you'll read them in 2 months?
2018-03-29T05:17:54 < dongs> sinec you picked free shipping
2018-03-29T05:20:27 < dongs> haha. dickstarter pals bought me those bose noise cancelling jewtooth headphones
2018-03-29T05:20:33 < dongs> i power it up, it needs firmware update
2018-03-29T05:20:46 < dongs> its been 'transferring' firmware to the phones at something like 10%/4minutes
2018-03-29T05:26:26 < johntramp> is it usual for the link register to be out by one byte from the disassembly instruction address?
2018-03-29T05:26:35 < dongs> 'link'?
2018-03-29T05:27:31 < johntramp> https://en.wikipedia.org/wiki/Link_register
2018-03-29T05:31:23 < Thorn> yes, the LSB is the mode indicator. for cortex-m it must always be 1
2018-03-29T05:31:41 < johntramp> ah ok
2018-03-29T05:31:43 < Thorn> same for interrupt vectors

2018-03-29T05:32:29 < Thorn> arm/thumb mode indicator. arm=0, thumb=1
2018-03-29T05:32:53 < johntramp> oh right, that was my next question :)
2018-03-29T05:34:25 < Thorn> it's an attempt at maintaining code compatibility with cortex-a (which supports arm mode) or something but in practice it only adds to confusion
2018-03-29T05:34:52 < johntramp> can you recommend any reading on the topic?  the arm reference manuals can be a bit overwhelming
2018-03-29T05:35:42 < Thorn> latest editions of all Joseph Yiu books
2018-03-29T05:36:38 < johntramp> cool, thanks
2018-03-29T05:38:43 < Cracki> *bookmark*
2018-03-29T05:38:50 < Thorn> (I've no idea why they decided to keep the ARM mode in the Cortex generation at all, thumb-2 is good enough to be universal imo)
2018-03-29T05:40:00 < Ultrasauce> ya i bet that sensor is just a reed switch, the axial leads (and price) kind of give it away
2018-03-29T05:41:21 < Thorn> afaict there are 2 designs: one has a spring-loaded contact with a weak enough spring so it breaks contact momentarily when vibrated
2018-03-29T05:41:35 < Thorn> the other is an inductor with a core on a spring
2018-03-29T05:41:46 < dongs> o yeah
2018-03-29T05:41:49 < dongs> the second one sounds more likely
2018-03-29T05:41:51 < dongs> in that kinda setup
2018-03-29T05:42:07 < dongs> so when it wobbles it generates some voltage and that opamp/comparator thing switches
2018-03-29T05:42:10 < Ultrasauce> be nice if they had a monostable on there

2018-03-29T07:18:17 < Thorn> which 4 t12 tips to order
2018-03-29T07:21:35 < englishman> T12-1010
2018-03-29T07:23:16 < Thorn> I chose T12-K, T12-BCF2, T12-D16, T12-D4 (they don't seem to have BCM)
2018-03-29T07:23:52 < Thorn> (is K useful?)
2018-03-29T07:28:08 < dongs> holy shit ipv6 is amazing
2018-03-29T07:28:15 < dongs> i can ssh to my rageberrypi even tho its on my local network
2018-03-29T07:28:45 < Thorn> wat
2018-03-29T07:29:27 < dongs> i hve native ipv6 from my provider
2018-03-29T07:29:36 < dongs> so just plug stuff in and it automatically gets ipv6 global address
2018-03-29T07:29:56 < dongs> i have a random remote box that also has ipv6, so it can ping/connect to rageberry directly
2018-03-29T07:30:48 < Thorn> oh so you mean you can ssh from the outside
2018-03-29T07:31:06 < Thorn> what about T12-KR, T12-BCF2, T12-D16, T12-DL32

2018-03-29T07:39:17 < Cracki> you get a /64 prefix to your router, and the lan is mapped into that
2018-03-29T07:42:09 < dongs> how many ips is that in /64
2018-03-29T07:42:11 < dongs> 25^?
2018-03-29T07:42:15 < dongs> er 256?
2018-03-29T07:48:16 < Cracki> 2^64 remainin
2018-03-29T07:48:17 < Cracki> g
2018-03-29T07:48:19 < Cracki> 128 bits total
2018-03-29T07:48:35 < Cracki>  /64 is the number of bits in the prefix/network part
2018-03-29T07:48:53 < Cracki> you can map MACs into it
2018-03-29T07:49:18 < Cracki> which is a security risk, which is why your devices preferably use something random
2018-03-29T07:49:50 < Cracki> put another way, you could give every byte in all of your storage its own ip
2018-03-29T07:50:21 < Cracki> there have been people who transmitted data in the local bits of address, and just sent around ping packets

2018-03-29T07:51:11 < Cracki> an ISP gives nothing less than a /64 to each customer. getting a /56, /48 or /32 is common if you're a company

2018-03-29T11:40:36 < dongs> if I have a fairly high switching freq and i don't have any 2.2uh inductor but light load can i sub with 1.5 or 4.7 which would be better?
2018-03-29T11:40:46 < dongs> sw freq is 2mhz
2018-03-29T11:41:16 < jadew> higher is better
2018-03-29T11:41:50 < jadew> if 2.2 was what you needed, then going lower means you will get worse output
2018-03-29T11:42:27 < jadew> (since it will saturate faster and then it will start following the input)
2018-03-29T11:42:35 < dongs> ok
2018-03-29T11:42:43 < dongs> 4.7 it is
2018-03-29T11:44:17 < jadew> I guess it depends on the load too... if by light load you mean lower than you designed it for... then maybe 1.5 is also fine
2018-03-29T11:44:32 < dongs> load is like 30mA
2018-03-29T11:44:42 < dongs> and shit's spec'd for liek 3A
2018-03-29T11:45:26 < jadew> then the other one will probably work just as well

2018-03-29T14:28:49 < microx> Hi, what could be the reason for NRST to get pulled low by the stm32f0?
2018-03-29T14:29:07 < microx> NRST is wired up with 100k to 3.3V
2018-03-29T14:29:27 < Thorn> nrst is i/o on stm32
2018-03-29T14:29:50 < Thorn> it will generate a pulse on nrst when it resets
2018-03-29T14:29:55 < PaulFertser> But the watchdog reset generates a pulse, not constant pull.
2018-03-29T14:30:27 < microx> I did not load any firmware and set boot0 to 1 so it should start up in USB HID mode no?
2018-03-29T14:30:45 < microx> I'm using STM32F072

2018-03-29T14:47:51 < jpa-> microx: atleast if VDDA is disconnected it will pull NRST down
2018-03-29T14:48:03 < jpa-> also if the cpu resets itself, it will also pull the external NRST down for a pulse

2018-03-29T15:01:09 < dongs> im getting orders of magnitude higher Iq from that LTC part than waht datasheet claims
2018-03-29T15:01:18 < dongs> im getting 360uA regulating 14V to 5V
2018-03-29T15:01:26 < dongs> datasheet claims 2.5uA 12V to 3.3V

2018-03-29T15:02:27 < jpa-> divider calc is correct
2018-03-29T15:02:29 < jpa-> which part?

2018-03-29T15:03:21 < jpa-> but isn't the divider on the output?
2018-03-29T15:03:25 < jpa-> so 5V/...?
2018-03-29T15:03:27 < dongs> on input
2018-03-29T15:03:33 < dongs> you mean fb?

2018-03-29T19:05:45 < englishman> you mean jump out of dfu bootloader and go to software?

2018-03-29T19:07:59 < englishman> what is the question you are asking
2018-03-29T19:08:11 < englishman> you want to set the chip to enter dfu, but then have it not enter dfu?
2018-03-29T19:08:55 < microx_> I want to connect the device initially - upload the firmware via USB - reconnect the unit and it should stay in the vendor specific mode
2018-03-29T19:09:24 < microx_> it should not stay in DFU mode anymore once the firmware is uploaded
2018-03-29T19:09:46 < englishman> does the chip have empty-chip detection
2018-03-29T19:09:57 < englishman> most new ones go to dfu if flash is unprogrammed

2018-03-29T20:38:40 < upgrdman> whats a cheap way to store ~1MByte of data? guessing SPI flash, but i don't need non-volatile.
2018-03-29T20:39:00 < upgrdman> anything cheaper? need speed of ~20MBit/sec
2018-03-29T20:39:09 < Cracki> you wanna mess around with some kind of volatile ram?
2018-03-29T20:39:14 < Cracki> spi flash.
2018-03-29T20:39:23 < upgrdman> i dont want to. but what's cheaper? anything?
2018-03-29T20:39:27 < Steffanx> What's cheap?
2018-03-29T20:39:34 < upgrdman> cheaper than spi flash
2018-03-29T20:39:34 < Cracki> spi flash is not cheap enough?
2018-03-29T20:39:48 < upgrdman> Cracki, just looking at options.
2018-03-29T20:39:57 < Steffanx> Buy 10000 and spi flash is cheap.
2018-03-29T20:40:17 < upgrdman> so in other words, spi flash is the cheapest option. fine. that's all i wanted to know.
2018-03-29T20:40:30 < Cracki> aliexpress, 8mbit spi flash, 10pcs = 2.50 bucks
2018-03-29T20:40:45 < Steffanx> i think so. im pretty sure its cheaper than anything volatile.
2018-03-29T20:40:49 < Rickta59> you could put the data on the internet and use an esp8266
2018-03-29T20:41:02 < Steffanx> lol
2018-03-29T20:41:06 < Cracki> you could beam it to the moon and back, you'll get ~2.5 seconds of delay
2018-03-29T20:41:23 < Steffanx> Cheap?
2018-03-29T20:41:41 < Cracki> if you can steal the equipment, sure
2018-03-29T20:41:51 < Cracki> also, how many write cycles anticipated?

2018-03-29T21:42:26 < Cracki> opamps are characterized by their bandwidth-gain-product. start with that.

2018-03-29T23:16:03 < upgrdman> if anyone uses openvpn+stunnel on their android phones: you can use ssldroid + openvpn for android. be sure to whitelist ssldroid in openvpn. i used to use ssldroid + openvpn connect, but in modern versions of android it fucks shit up and tried to run ssldroid through the vpn, which immediately kills the vpn connection.
2018-03-29T23:16:23 < upgrdman> and it looks like openvpn connect has no whitelist feature

2018-03-29T23:49:19 < englishman> Due to flash size limitations, some features of OpenThread are not supported on the Texas Instruments CC2650. This platform is intended for exprimentation and exploration of OpenThread, not a production ready environment. Texas Instruments recommends future TI SoCs for production.
2018-03-29T23:49:21 < englishman> lol
2018-03-29T23:49:48 < englishman> Building the examples for the cc2650 requires GNU AutoConf, GNU AutoMake, Python, and the ARM gcc toolchain.

2018-03-29T23:58:31 < zyp> already had a couple other guys asking about when I'll make more too, so I figure I'll break even soon enough
2018-03-29T23:59:26 < upgrdman> pretty sure the answer is no, but are there any 4k cameras that are easy to talk to with an stm32? obviously at like 1fps but that's fine

2018-03-30T01:50:12 < catphish> a transformer seems kinda easy by comparison

2018-03-30T03:10:52 < catphish> i'm worried about how to get the boost converter right though
2018-03-30T03:11:30 < catphish> there is always a chance i give up and just accept that i will need a bigger battery, but it would be cool if it worked

2018-03-30T03:13:18 < zyp> cool, EVs are fun
2018-03-30T03:13:43 < catphish> something simple first, like a go kart, my mechanical skills aren't great :)

2018-03-30T03:14:11 < zyp> so, you want a boost converter because your battery voltage is too low?
2018-03-30T03:14:21 < catphish> zyp: yes
2018-03-30T03:14:38 < catphish> it's difficult to build and maintail a 300v+ battery

2018-03-30T03:14:51 < zyp> sounds like a complicated solution when you could just change the battery topology instead
2018-03-30T03:15:05 < catphish> perhaps

2018-03-30T03:15:24 < catphish> i suspect the whole thing will work better if i just use more cells
2018-03-30T03:16:39 < catphish> the boost certainly makes the control more complicated
2018-03-30T03:17:18 < zyp> I think my car is something like 88S3P
2018-03-30T03:17:30 < catphish> DC?
2018-03-30T03:17:52 < catphish> i mean dc everything?
2018-03-30T03:18:04 < zyp> everything what?
2018-03-30T03:18:46 < catphish> oh, i just got what you meant by 88S3P

2018-03-30T03:19:11 < catphish> awesome
2018-03-30T03:19:27 < catphish> sounds pricey
2018-03-30T03:19:54 < zyp> in what sense?
2018-03-30T03:20:10 < catphish> expensive to buy
2018-03-30T03:20:39 < zyp> depends how you look at it
2018-03-30T03:20:41 < catphish> just looked it up, not expensive as i thought it might be
2018-03-30T03:20:44 < zyp> what country are you in?
2018-03-30T03:20:46 < catphish> uk
2018-03-30T03:21:10 < catphish> its about twice the price of my 5 year old gti, so not so bad

2018-03-30T03:21:55 < zyp> I'm in Norway, EVs are exempt from both VAT and other fees here
2018-03-30T03:22:13 < catphish> that's cool
2018-03-30T03:22:53 < zyp> IIRC when I bought it, the base-model egolf were actually on-par with the cheapest gasoline golf or so
2018-03-30T03:22:57 < catphish> i think they tried that here, too many rich people bought teslas and avoided the tax, not really what they wanted
2018-03-30T03:23:03 < zyp> with a higher base equipment level
2018-03-30T03:23:08 < zyp> haha, idk
2018-03-30T03:23:12 < catphish> that's awesome
2018-03-30T03:23:22 < zyp> that happens here too, I don't see the problem with it
2018-03-30T03:23:47 < aandrew> heh
2018-03-30T03:23:55 < zyp> the whole point of the subsidies is to get people to buy «green» cars, so what if it's a tesla
2018-03-30T03:23:56 < aandrew> I bought a brand new TDI passat 5y ago

2018-03-30T03:24:02 < catphish> so i'd need 27 x 12v lead acid batteries, or 90 x lithium cells
2018-03-30T03:24:53 < aandrew> I'm pretty happy with it. 5.8L/100km for average daily driving and wintertime highway is about 4.9. If the ambient temp stays above about 6C that'll drop to 5.2L/100km city and 4.5ish hwy
2018-03-30T03:24:58 < catphish> zyp: i suspect it's complicated, one tesla is a huge tax saving, but not much environmental benefit i guess
2018-03-30T03:25:12 < catphish> i don't like diesel for some reason
2018-03-30T03:25:15 < zyp> 90 18650s isn't really a lot, about two ebike packs worth
2018-03-30T03:25:30 < catphish> 90 x 18650 would be ideal
2018-03-30T03:25:37 < zyp> then just parallelize up until you get the current you need
2018-03-30T03:25:46 < catphish> expensive though
2018-03-30T03:26:16 < zyp> compared to what?
2018-03-30T03:26:31 < aandrew> ^^
2018-03-30T03:26:43 < catphish> compared to less cells :)
2018-03-30T03:26:52 < zyp> a battery that can deliver serious power will be expensive no matter what topology
2018-03-30T03:27:16 < catphish> i could use mains with a good rectifier for testing
2018-03-30T03:27:34 < zyp> consider this; power capacity scales with cell count, no matter the topology
2018-03-30T03:28:01 < zyp> a low voltage battery and a stepup will need more current capacity than a high voltage battery for the same output power
2018-03-30T03:28:23 < englishman> in the uk that burns oil and gas, electric cars aren't so great environmentally
2018-03-30T03:28:32 < englishman> vs. 1st world countries like norway anyway
2018-03-30T03:29:37 < catphish> my power is 100% renewable
2018-03-30T03:30:04 < catphish> though many people do indeed use gas still
2018-03-30T03:31:00 < catphish> these are great https://eu.nkon.nl/rechargeable/18650-size/samsung-18650-inr18650-25r.html
2018-03-30T03:31:14 < zyp> englishman, as far as I've read, the efficiency still makes them a net win over the total lifecycle, even if the margins are smaller than when powered from renewable sources
2018-03-30T03:31:16 < catphish> i'd have to build a pack, but maybe worth it
2018-03-30T03:32:04 -!- BoyHolthausen [boyholthau@gateway/shell/matrix.org/x-jwmperzgwituczoe] has joined ##stm32
2018-03-30T03:32:29 < catphish> €252 for 90s1p 2500mah
2018-03-30T03:32:42 < zyp> look at people building batteries for ebikes
2018-03-30T03:33:33 < zyp> you get nice plastic matrices and stuff to hold the batteries in place
2018-03-30T03:33:36 < englishman> maybe, a lot of analysis needs to be done in total material lifecycle
2018-03-30T03:36:47 < zyp> catphish, finding a suitable charger might be a challenge though
2018-03-30T03:37:24 < catphish> zyp: yeah, charging a pack that size probably requires some special thought
2018-03-30T03:38:06 < catphish> another reason i was avoiding large cell counts
2018-03-30T03:38:50 < zyp> a bunch of independent BMSes is easy enough, but chargers for a system voltage over 60V is probably gonna be a problem
2018-03-30T03:39:12 < zyp> might be easiest to just break it down into independent packs for charging
2018-03-30T03:39:29 < catphish> almost certainly
2018-03-30T03:39:40 < catphish> multiple isolated chargers would work
2018-03-30T03:40:07 < zyp> you could do 7x13S and use 48V ebike chargers
2018-03-30T03:40:26 < catphish> seems sane
2018-03-30T03:42:57 < zyp> or this thing: http://www.ebikes.ca/cycle-satiator-72v-5a.html
2018-03-30T03:43:12 < catphish> rectifying the mains for testing has the same problem as using a transformer based supply, no way to get rid of excess power from the dc bus
2018-03-30T03:43:52 < zyp> excess power?
2018-03-30T03:44:18 < catphish> regenerative braking potentially puts power from the motor back onto the bus
2018-03-30T03:44:28 < catphish> need a way to dissipate it
2018-03-30T03:44:32 < zyp> ah, true
2018-03-30T03:44:54 < catphish> a battery solves this problem for free :)
2018-03-30T03:45:17 < catphish> perhaps i'll look at battery options then
2018-03-30T03:45:38 < catphish> i'm currently testing with lipo packs, they're cheap and really convenient
2018-03-30T03:46:16 < zyp> a dump load isn't expensive though, just some old resistive heater
2018-03-30T03:46:35 < catphish> https://hobbyking.com/en_us/turnigy-2200mah-3s-25c-lipo-pack.html
2018-03-30T03:46:41 < catphish> i have a stack of these
2018-03-30T03:47:17 < catphish> resistor bank would work, with some voltage sensing to turn it on as needed
2018-03-30T03:47:45 < zyp> I was thinking about some old panel heater
2018-03-30T03:48:13 < catphish> yeah, that would work, same thing really
2018-03-30T03:48:14 < zyp> they're already designed to dissipate a couple kilowatts
2018-03-30T03:49:07 < zyp> with a battery you need to be careful not to overcharge it
2018-03-30T03:49:49 < zyp> my car does almost no regenerative braking when the battery is close to full
2018-03-30T03:49:52 < catphish> zyp: true, though it would be quite unlikely
2018-03-30T03:50:10 < catphish> unless you live at the top of a hill
2018-03-30T03:50:27 < catphish> but yes, need to be sure not to
2018-03-30T03:51:24 < catphish> well, i'll keep going with batteries, maybe design something to hold / plug / fuse a large number of them safely
2018-03-30T03:51:34 < zyp> I've had my car report a net-negative consumption over something like 20km driven
2018-03-30T03:51:46 < catphish> zyp: impressive
2018-03-30T03:51:58 < zyp> starting at about sea level :)
2018-03-30T03:52:13 < catphish> that seems impossible
2018-03-30T03:52:39 < zyp> I might be wrong about the distance, let me look at a map
2018-03-30T03:53:24 < zyp> probably more like 15km
2018-03-30T03:53:25 < catphish> it takes a lot of energy to move a car
2018-03-30T03:53:59 < catphish> i can't fathom how you'd get a zero net energy use unless it was substantially downhill
2018-03-30T03:54:08 < zyp> well, it was
2018-03-30T03:54:33 < zyp> undersea tunnel :)
2018-03-30T03:54:44 < catphish> lol
2018-03-30T03:54:50 < catphish> well that works
2018-03-30T03:55:12 < zyp> they are pretty steep and deep, so you recover a lot of energy on the way down
2018-03-30T03:55:21 < catphish> cool
2018-03-30T03:55:33 < zyp> hmm, I'm actually gonna be driving through the same tunnel tomorrow
2018-03-30T03:55:41 < zyp> kinda doubt I can repeat it though
2018-03-30T03:56:15 < catphish> well perhaps i'll dump the boost converter from my design and go simple :)
2018-03-30T03:56:29 < zyp> at this time of the year, heating eats a lot of extra energy
2018-03-30T03:56:42 < catphish> heating is for wimps
2018-03-30T03:57:14 < zyp> drove around 300km today, think I averaged around 15kWh/100km
2018-03-30T03:57:25 < zyp> in the summer it would have been below 12
2018-03-30T03:58:20 < zyp> well, heating eats energy, cold air is denser than hot air, winter tires have more friction than summer tires, etc…
2018-03-30T03:58:52 < catphish> i fear i drive too fast to get any sort of efficiency

2018-03-30T04:01:38 < zyp> the thing about EVs is that they don't throw a lot of energy out the exhaust pipe just by running, so every small extra resistance makes a pretty noticeable difference on the total power consumption

2018-03-30T06:04:42 < branjb> anyone used rust on stm32?
2018-03-30T06:05:05 < dongs> i bet o6 have
2018-03-30T06:05:10 < dongs> also you should kill yourself for even considering
2018-03-30T06:05:13 < dongs> rust is for faggots
2018-03-30T06:06:03 < branjb> not my choice
2018-03-30T06:06:11 < dongs> rust is never a choice
2018-03-30T06:06:52 < branjb> i'm just gonna wrap my main in [unsafe] and write everything in assembly
2018-03-30T06:06:55 < branjb> think that meets intent?

2018-03-30T06:16:26 < Cracki_> upgrdman, "nobody has ever been fired for using qt" but ya, the only alternative gui toolkits would also mean switching languages (c#...)
2018-03-30T06:17:13 < Cracki_> qt has a verrry strong commercial backing
2018-03-30T06:17:25 < upgrdman> ya im not against c# but the reason why im looking to c++ is to eek out more performance by not using a managed language
2018-03-30T06:17:33 < Cracki_> looks nice, gets architectural love, ...
2018-03-30T06:17:52 < Cracki_> personally I have no experieence with c#, but I wouldn't worry much about that
2018-03-30T06:18:04 < upgrdman> i also need to find a good c++ book that hopefully covers modern c++ (17 or at least 14)
2018-03-30T06:18:15 < Cracki_> they have enough skin in the game to work really hard on c# performance
2018-03-30T06:19:02 < Cracki_> well it's not a book but there's cppreference.com and I think it lists additions and changes for every new revision of c++
2018-03-30T06:21:38 < upgrdman> ya i need a pdf.
2018-03-30T06:21:47 < upgrdman> i'll be sitting in a plane for 14 hours
2018-03-30T06:22:23 < Cracki_> if you ask the c++ people, they might recommend you something that's heavy on the templating and type system

2018-03-30T07:07:54 < R0b0t1> Well I figured out how the MEMS MIC example works. It has very little to do with the Cube program. It's a standalone project tree.
2018-03-30T07:07:59 < R0b0t1> Bad news: it doesn't work.
2018-03-30T07:08:15 < R0b0t1> Some day friends, I will have a working product. Some day.
2018-03-30T07:09:04 < R0b0t1> upgrdman: C# is theoretically an amazing language but it ties you to Windows despite the existence of Mono and .NET Core.
2018-03-30T07:09:23 < englishman> sounds like a feature, not a bug
2018-03-30T07:09:47 < R0b0t1> Every once and a while I have the amazingly bad idea to do something in C#. It ends up okay, but then you hit a wall where all of the C# bindings for ${library} are broken or missing.
2018-03-30T07:09:55 < R0b0t1> It starts out*
2018-03-30T07:10:12 < R0b0t1> It really works best as a langauge for making MVC applications

2018-03-30T07:14:51 < upgrdman> R0b0t1, ya well i use java right now. if im going to invest a lot of time in another language, i'd rather something lower-level.
2018-03-30T07:15:19 < upgrdman> its just annoying reading about lots of awesome profiling stuff, and not being able to benefit as much from it when using a managed lang
2018-03-30T07:15:50 < upgrdman> kinda want to play with SIMD and see how badly im thrashing caches etc.
2018-03-30T07:26:56 < R0b0t1> Java is probably the better choice
2018-03-30T07:27:46 < R0b0t1> Well, GCC is cross platform. I've had good luck with MinGW. Distributing binaries can be a bit strange (make everything static).
2018-03-30T07:28:25 < R0b0t1> You might want to look at FreePascal, depending on taste. I find it makes me a lot more productive, but it can have the same problem as C#. It is easier to use C code from it, though.
2018-03-30T07:28:47 < R0b0t1> Can do SIMD/whatever in it since it compiles to machine code
2018-03-30T07:29:11 < R0b0t1> But it has a very developed class system
2018-03-30T07:29:34 < R0b0t1> But you didn't ask for my opinion
2018-03-30T07:29:36 < R0b0t1> I'll stow it
2018-03-30T07:29:49 < upgrdman> its cool

2018-03-30T10:43:14 < Haohmaru> according to what i found, newlib is GPL or LGPL, right?
2018-03-30T10:45:12 < Haohmaru> (amongst other licenses, my concern is what i can and cannot use for closed-source product)
2018-03-30T10:46:01 < zyp> no.
2018-03-30T10:46:25 < Haohmaru> no as in, it's GPL and thus i can't use it?
2018-03-30T10:46:49 < zyp> no as in «no, you're wrong»
2018-03-30T10:47:00 < Haohmaru> oh?
2018-03-30T10:47:25 < zyp> newlib consists of a mix of code under different licenses, of which most seems to be BSD/MIT-ish
2018-03-30T10:47:28 < zyp> ref. https://sourceware.org/newlib/COPYING.NEWLIB
2018-03-30T10:47:42 < Haohmaru> yeah, i saw that, and inside there i saw at least LGPL
2018-03-30T10:48:12 < zyp> «(21) Free Software Foundation LGPL License (*-linux* targets only)»
2018-03-30T10:48:37 < zyp> I read that as LGPL doesn't apply unless you're building for linux

2018-03-30T10:51:34 < Haohmaru> so the LGPL doesn't apply for "bare metal" usage?
2018-03-30T10:51:48 < Haohmaru> how about newlib-nano? in that, i saw GPL
2018-03-30T10:52:16 < zyp> only the licenses of the code going into your binary applies
2018-03-30T10:52:31 < zyp> because that's the only code you're deriving from/redistributing
2018-03-30T10:52:39 < Haohmaru> i'm very confused, because i installed gcc-arm-none-eabi on debian, and it came together with a few other packages including newlib and i think libstc++
2018-03-30T10:53:05 < zyp> yeah?
2018-03-30T10:53:30 < Haohmaru> and i have /usr/include/newlib
2018-03-30T10:55:31 < zyp> so?
2018-03-30T10:56:05 < Haohmaru> specifically, i want to use stm32F4, with C++, so i already tried cubeMX, generated some code (which was in C, with the "HAL" and the makefiles didn't work), but i managed to feed those files into my IDE and built them from there
2018-03-30T10:56:38 < zyp> yeah?
2018-03-30T10:57:15 < Haohmaru> but cubemx is very heavy and smells a bit ardweeny, so i think i'm better off with CMSIS and making my own HAL or whatever
2018-03-30T10:58:40 -!- boB_K7IQ [boB_K7IQ@c-73-254-117-163.hsd1.wa.comcast.net] has joined ##stm32
2018-03-30T10:59:00 < zyp> that's up to you
2018-03-30T11:00:51 < Haohmaru> but i need C++ (at least constructors/RAII)
2018-03-30T11:00:51 < zyp> I sort of went that route, but I don't use CMSIS either, I write my own register definitions
2018-03-30T11:01:11 < Haohmaru> i can live without many of the fancy things like vectors lists maps and algorithms..
2018-03-30T11:01:27 < zyp> C++ should be supported with anything, really
2018-03-30T11:05:34 < zyp> RAII doesn't have external dependencies, that's just the compiler inserting implicit constructor/destructor calls in the caller function
2018-03-30T11:05:46 < Haohmaru> i'm not a asm h4x0r and don't understand processors too much, so i would not want to write my own register definitions, i believe CMSIS is meant to work fine with C++
2018-03-30T11:06:23 < zyp> for global objects, the startup code needs to handle initializer lists to call the constructors for those, but any decent startup code should already do that
2018-03-30T11:06:39 < Haohmaru> so i take CMSIS from arm.com, and then i need the chip-specific headers from stm, i think they come in the stm32cubeF4 or some such
2018-03-30T11:06:47 < PaulFertser> Haohmaru: have you considered https://github.com/andysworkshop/stm32plus/ ? BSD-style license.
2018-03-30T11:07:17 < zyp> i.e. outside of the right makefile rules, all you need for basic C++ support is startup code that does initializers properly
2018-03-30T11:07:44 < zyp> oh, and headers that wraps C declarations in extern "C" blocks
2018-03-30T11:07:53 < Haohmaru> PaulFertser, i feel dumb, i see that for the first time.. i hate google but google hates me back it seems
2018-03-30T11:08:11 < Haohmaru> i've no idea what it is, i'll have to check it out in detail
2018-03-30T11:08:25 < zyp> you could also have a look at my lib: https://cgit.jvnv.net/laks/
2018-03-30T11:08:50 < zyp> but I'd advise against using it unless you know what you're doing, it's not very mature
2018-03-30T11:09:06 < zyp> it mostly just supports stuff I've needed so far, I implement features as I need them
2018-03-30T11:09:15 < Haohmaru> yes, that's what i found so far, the startup code that comes from cubeMX i think doesn't include some stuff that will be needed for global-scope object constructors
2018-03-30T11:10:04 < zyp> idk, I'd have to read it to check
2018-03-30T11:10:31 < Haohmaru> i also found CMSIS++ which looked very promising, i downloaded it, but i couldn't make sense of how to use it, and i have the feeling that CMSIS++ is "tied" to the micro-os that it comes with, and i don't think i can easily figure out how to "untagle" it
2018-03-30T11:12:29 < PaulFertser> Haohmaru: if you decide to try stm32plus, please share your experience here. Should be working pretty much out of the box it seems.
2018-03-30T11:13:03 < Haohmaru> i'm looking for a description of what it is and what it can (or can't) do
2018-03-30T11:13:29 < PaulFertser> Haohmaru: scroll down on https://github.com/andysworkshop/stm32plus
2018-03-30T11:14:03 < zyp> my lib is mostly a usb stack now
2018-03-30T11:14:28 < zyp> it also got a nice GPIO API, but most other stuff is still on the register level
2018-03-30T11:15:10 < PaulFertser> stm32plus has usb device stack. Not sure about host.
2018-03-30T11:15:33 < zyp> bet my API is simpler though :)
2018-03-30T11:15:56 < Haohmaru> to give you some idea, i come from avr (xmega) and i use just what comes with avrlibc and i wrote my own classes for usarts, SPI, fifos, etc..

2018-03-30T11:16:52 < Haohmaru> but for the xmega there's really just one datasheet that explains all peripherals in detail, and another chip-specific datasheet
2018-03-30T11:16:56 < zyp> I've got a similar background
2018-03-30T11:17:21 < zyp> stm32 isn't all that different
2018-03-30T11:17:36 < Haohmaru> it's harder
2018-03-30T11:17:42 < zyp> each family (or subfamily) got a reference manual describing all the peripherals and registers
2018-03-30T11:17:43 < Haohmaru> i can't make sense of it still ;]
2018-03-30T11:18:04 < zyp> and then each chip gets a datasheet describing the hardware details like pinout and so on
2018-03-30T11:18:15 < Haohmaru> yeah i downloaded like 6 or more documents from ST that cover different aspects of the chip i selected
2018-03-30T11:18:36 < zyp> and then there's a few peripherals in the ARM core itself that's documented by ARM rather than ST
2018-03-30T11:19:20 < zyp> but between the ARM reference manual, the stm32 family reference manual and the chip datasheet, pretty much everything is covered
2018-03-30T11:19:29 < Haohmaru> so that's why i was thinking that CMSIS will give me pretty much the equivalent of what comes with #include <avr/io.h>
2018-03-30T11:20:24 < zyp> to me the name CMSIS isn't entirely unambiguous though so YMMV
2018-03-30T11:20:38 < Haohmaru> yeah, that's confusing too
2018-03-30T11:20:42 < zyp> but you can certainly get header files with only register definitions like you want
2018-03-30T11:20:58 < Haohmaru> CMSIS alone (from arm) is incomplete because it does not include any vendor-specific things at all
2018-03-30T11:21:17 < Haohmaru> so i have to add CMSIS-related files from ST
2018-03-30T11:21:26 < Haohmaru> right?
2018-03-30T11:21:31 < zyp> I ended up not bothering with any third party headers
2018-03-30T11:21:39 < Haohmaru> :/
2018-03-30T11:21:44 < PaulFertser> libopencm3 doesn't use vendor headers either
2018-03-30T11:21:58 < Haohmaru> how is that possible?
2018-03-30T11:22:04 < stvn> Meow
2018-03-30T11:22:06 < zyp> it takes me less time in the long run to type out a register struct myself than to maintain a third party dependency
2018-03-30T11:22:18 < Haohmaru> hm
2018-03-30T11:22:24 < zyp> https://cgit.jvnv.net/laks/tree/gpio/gpio.h <- consider this
2018-03-30T11:22:57 < zyp> lines 6-27 and 202-231 is what such a header would give you
2018-03-30T11:23:27 < zyp> the names and offsets are all documented in the reference manual, so it doesn't take long to type off
2018-03-30T11:23:59 < Haohmaru> yeah, the avr headers for xmega are similar (C)
2018-03-30T11:24:11 < PaulFertser> Can also be generated from vendor's SVD files.
2018-03-30T11:24:14 < Haohmaru> i made my own "pin" classes to make things easier for me
2018-03-30T11:24:32 < PaulFertser> (what is rust community does for stm32 programming)
2018-03-30T11:24:56 < Haohmaru> but my impression was that CMSIS is a good thing
2018-03-30T11:25:08 < Haohmaru> that is, at least the ARM side of it
2018-03-30T11:25:32 < Haohmaru> the ST-specific code that should go into CMSIS was not very clear to me
2018-03-30T11:25:32 < zyp> PaulFertser, yeah
2018-03-30T11:25:57 < zyp> but SVD files is another form of a third-party dep and I'm not convinced about the quality of the source material :)
2018-03-30T11:26:50 < Haohmaru> bear in mind i don't understand asm, makefiles, and program structure on the low level
2018-03-30T11:27:14 < Haohmaru> so i'm not confident enough to make my own register definitions like you
2018-03-30T11:27:16 < zyp> maybe that's something to work on then :)
2018-03-30T11:27:21 < Haohmaru> i'll mess things up
2018-03-30T11:27:27 < dongs> zyp, last time it was 148 boards or someshit
2018-03-30T11:27:28 < dongs> same process?
2018-03-30T11:27:36 < dongs> whatever one fr4 is
2018-03-30T11:27:36 < Haohmaru> i don't have enough time, that's the other problem
2018-03-30T11:27:44 < dongs> < Haohmaru> bear in mind i don't understand asm, makefiles, and program structure on the low level

2018-03-30T11:28:09 < Haohmaru> was that an IDE?
2018-03-30T11:28:09 < zyp> dongs, hmm, was that natural panel size or something?
2018-03-30T11:28:14 < dongs> zyp, yes
2018-03-30T11:28:20 < dongs> do you remember how many i sent you last time?
2018-03-30T11:28:31 < PaulFertser> Haohmaru: my impression is that most code/headers that come from ST is shit. So when choosing C++ I'd just try stm32plus. Or libopencm3 which can be used in a C++ project too.

2018-03-30T11:28:57 < dongs> hm
2018-03-30T11:29:00 < dongs> looks like last time it was 190?
2018-03-30T11:29:07 < dongs> multiples of 8mhz xtal
2018-03-30T11:29:07 < zyp> no, I remember the earlier batches were 112 each, and last one was like +50% or so
2018-03-30T11:29:11 < dongs> oh
2018-03-30T11:29:27 < dongs> i have invoice from 2017/2 that says you got 190 of SSTM32F303 etc
2018-03-30T11:29:35 < dongs> ok, anyway, you're after whatever FR4 size right
2018-03-30T11:29:48 < zyp> maybe like 148 boards on a new panel, plus leftover boards from earlier
2018-03-30T11:29:50 < Haohmaru> PaulFertser, i also read some bad comments about the ST code, that's why i dropped cubeMX from consideration.. i looked into opencm3 but it's LGPL or GPL (i forgot)
2018-03-30T11:29:57 -!- gnom [~aleksande@178.150.7.153] has joined ##stm32
2018-03-30T11:30:02 < Haohmaru> i still have to look into stm32plus
2018-03-30T11:30:10 < dongs> ok ill see if tehres any left, but im not sure if so
2018-03-30T11:30:17 < dongs> i think the 190 was leftover + new FR4
2018-03-30T11:30:18 < zyp> yeah, I don't really have a strict target number, I figure they'll sell eventually anyway
2018-03-30T11:30:24 < zyp> yeah, that's what I just said
2018-03-30T11:30:26 < dongs> so i think there's nothing left
2018-03-30T11:30:38 < PaulFertser> Haohmaru: LGPL. But it doesn't mean you absolutely can't use it in a proprietary project. Just distribute your proprietary code in .o files and do not use inline functions from the library.
2018-03-30T11:31:06 < Haohmaru> yeah, that's what i found out too
2018-03-30T11:31:33 < Haohmaru> so it's still an option, but the boss might not like it
2018-03-30T11:31:44 < dongs> oh, i found my notes
2018-03-30T11:31:49 < dongs> arcin 56*2 (fr4)
2018-03-30T11:31:52 < dongs> so its 112
2018-03-30T11:32:50 < zyp> yeah, that's what the old batches were
2018-03-30T11:32:51 < Haohmaru> another thing that confuses me is.. there's the "startup code" which afaik can be written in ASM or C or even C++ or any combination of those, and there's that .ld file
2018-03-30T11:32:53 < PaulFertser> Haohmaru: basically, LGPL requires you to share all the changes/improvements to the library and provide end-users with means to relink your code against that library.
2018-03-30T11:32:54 < dongs> OK
2018-03-30T11:32:59 < dongs> getting that then
2018-03-30T11:33:07 < dongs> Haohmaru: what STM32
2018-03-30T11:33:12 < zyp> Haohmaru, yes
2018-03-30T11:33:31 < PaulFertser> Haohmaru: ld file basically tells the linker where the code and data will end up.
2018-03-30T11:33:36 < Haohmaru> PaulFertser, i know LGPL from PC programs, where the solution is dynamic linkage
2018-03-30T11:33:58 -!- kakimir [~kikkel@87-95-14-192.bb.dnainternet.fi] has quit [Ping timeout: 264 seconds]
2018-03-30T11:34:10 < PaulFertser> Haohmaru: if you ship your binary + a bunch of object files with your proprietary code and a Makefile to link all that together, that's about equivalent.
2018-03-30T11:34:12 < zyp> Haohmaru, the startup code prepares the environment like the compiler expects, which basically consists of three things
2018-03-30T11:34:27 < Haohmaru> so the ld file is very chip-specific but does it care about stuff like C++ global scope object constructors and stuff?
2018-03-30T11:35:22 < zyp> it zeroes the .bss segment (where zero-initialized global vars are stored), it copies the initial values for the .data segment from flash to ram (where nonzero-initialized global variables are stored) and then it calls initializers, which includes C++ global constructors
2018-03-30T11:35:22 < PaulFertser> Haohmaru: a bit, as the ld file needs to specify some sections that are needed for C++ internals but not needed for plain C.
2018-03-30T11:35:49 < zyp> https://cgit.jvnv.net/laks/tree/startup/entry.cpp <- a simple startup code looks like this
2018-03-30T11:35:53 < PaulFertser> Haohmaru: btw, it's no different to avr.
2018-03-30T11:36:09 < Haohmaru> PaulFertser, sure but in avr - "it just worked"
2018-03-30T11:36:16 < Haohmaru> and i have no idea how it does
2018-03-30T11:36:28 < zyp> avr-gcc automatically picks the right linker script for you
2018-03-30T11:36:29 < PaulFertser> Haohmaru: it was basically the same for me when I tried libopencm3 + C++ last time.
2018-03-30T11:36:33 < Haohmaru> (nor a big desire to know those details)
2018-03-30T11:36:51 < dongs> Haohmaru: what STM32 areyou planning to use
2018-03-30T11:36:57 < zyp> F4, he said
2018-03-30T11:37:00 < dongs> o
2018-03-30T11:37:01 < Haohmaru> for the first project F446
2018-03-30T11:37:09 < dongs> seems awfully specific
2018-03-30T11:37:32 < Haohmaru> we might need to use a small one for another project F0-something but that's later
2018-03-30T11:39:30 < dongs> so i missed the part about what is the actualyl concern here
2018-03-30T11:39:32 < dongs> commercial project?
2018-03-30T11:39:39 < dongs> use stdperiphlib or hal, done
2018-03-30T11:39:48 < dongs> avoid opensores
2018-03-30T11:39:51 < PaulFertser> Haohmaru: btw, with avr-gcc/avrlibc there's one "funny" gotcha. By default its linker scripts assume you have plenty of additional external SRAM. So if you overflow the internal memory, you get no indication whatsoever. I had to add "-Wl,--defsym=__DATA_REGION_LENGTH__=0x1000" for an atmega128 project which was far from obvious.
2018-03-30T11:40:00 < Haohmaru> zyp, can such "startup code" be not chip-specific? or can it be at least reused for the whole F4 family?
2018-03-30T11:40:14 < dongs> there's nothing chip specific in the link zyp pasted
2018-03-30T11:40:15 < zyp> yes, startup code is not chip specific at all
2018-03-30T11:40:28 < dongs> only the FPU shit
2018-03-30T11:40:32 < dongs> and thats for any M4 i guess
2018-03-30T11:41:00 < zyp> linker scripts are not very chip specific either, the only difference from one chip to another is ram/flash sizes
2018-03-30T11:41:00 < Haohmaru> PaulFertser, yeah i got bitten by that, i increased my FIFO buffers to 4x1024 bytes, forgot that the chip has 4K ram total, and it built and even *worked*
2018-03-30T11:41:10 < PaulFertser> Haohmaru: exactly
2018-03-30T11:41:26 < dongs> what avrturd supports external sram in any reasonable way?
2018-03-30T11:41:33 < dongs> is this some xmega  thing?
2018-03-30T11:41:41 < PaulFertser> Haohmaru: but with that additional obscure option I'm now getting a link-time error in cases like that.
2018-03-30T11:41:49 < Haohmaru> xmega and a few atmegas can have external SRAM/SDRAM
2018-03-30T11:42:01 < dongs> terrible
2018-03-30T11:42:03 < zyp> dongs, IIRC I used some atmega1280 with external sram interface once
2018-03-30T11:42:17 < PaulFertser> dongs: atmega128 in my case, no idea if it really supports external SRAM or not. It's not SDRAM.
2018-03-30T11:43:41 < dongs> https://scienceprog.com/adding-external-memory-to-atmega128/ wow
2018-03-30T11:43:55 < zyp> hmm, maybe it was 128, not 1280 I used
2018-03-30T11:44:37 < PaulFertser> What's stupid is that ld scripts assume this by default :/
2018-03-30T11:45:13 < zyp> actually, it might have been an AT90CAN128 or something, IIRC it was like an ATMEGA128 with CAN
2018-03-30T11:45:50 < zyp> used the external memory interface to run a parallel graphical lcd
2018-03-30T11:47:15 < zyp> about nine years ago, so I don't remember the details very well :)
2018-03-30T11:48:25 < stvn> Kool
2018-03-30T11:49:50 < Haohmaru> the xmega A that i use even has this DMA thing but i never got a chance to mess with it
2018-03-30T11:52:18 < Haohmaru> another question, when i include say, <stdint.h> - where should that be located? (i got like 3 flavors of gcc on this debian, and stdint.h probably in more than 3 places)
2018-03-30T11:53:01 < Haohmaru> i think even my IDE gets confused (i've probably messed up the settings)
2018-03-30T11:53:29 < PaulFertser> Haohmaru: you should be including <cstdint> ;)
2018-03-30T11:54:04 < PaulFertser> Haohmaru: when you use arm-none-eabi-gcc it should be using its own include path, you shouldn't be specifying anything extra.
2018-03-30T11:54:35 < Haohmaru> i need to tell my IDE where the includes are so that it can help me ;P~
2018-03-30T11:56:04 < Haohmaru> okay, so then is this the right file: /usr/include/newlib/c++/5.4.1/cstdint ?
2018-03-30T11:56:44 < zyp> probably
2018-03-30T11:56:56 < Haohmaru> k
2018-03-30T11:57:22 < PaulFertser> Haohmaru: arm-none-eabi-gcc -v 2>&1 | xargs -n1 | sed -n '/include.*dir/p'
2018-03-30T11:57:59 < PaulFertser> (eh, that last sed should be grep :)), damn you incremental development model)
2018-03-30T11:59:22 < Haohmaru> nothing happened

2018-03-30T12:02:30 < Haohmaru> hm
2018-03-30T12:03:04 < Haohmaru> does that mean that cstdint should be located somewhere in there?
2018-03-30T12:03:13 < PaulFertser> Haohmaru: for arm-none-eabi-gcc, seriously?
2018-03-30T12:03:23 < PaulFertser> Haohmaru: how did you install it?
2018-03-30T12:03:28 < Haohmaru> via synaptic
2018-03-30T12:03:43 < Haohmaru> debian9 (stable)
2018-03-30T12:04:45 < PaulFertser> Haohmaru: https://packages.debian.org/stretch/amd64/gcc-arm-none-eabi/filelist ?
2018-03-30T12:04:47 < Haohmaru> i'm getting very weird compile/link errors when i'm trying to build an example c++ ARM project (main.cpp just has an object declaration and some printf())
2018-03-30T12:05:37 < Haohmaru> PaulFertser, i think so, but it came together with a few other packages that "depended" on each other, including newlib
2018-03-30T12:06:05 < PaulFertser> Haohmaru: I'll try it on my Debian box now
2018-03-30T12:06:14 < Haohmaru> is there something fishy with this?
2018-03-30T12:06:17 < PaulFertser> (Debian testing)
2018-03-30T12:08:20 < PaulFertser> Haohmaru: hm, same includedir. I'd guess something is fishy, yes.
2018-03-30T12:08:49 < Haohmaru> :/
2018-03-30T12:08:59 < Haohmaru> me and my luck again
2018-03-30T12:09:56 < PaulFertser> Haohmaru: I'll try to compile a project and will see what it gives, probably that's in fact ok.
2018-03-30T12:12:20 < PaulFertser> Haohmaru: in fact "arm-none-eabi-cpp -v" returns a sensible include path, so you shouldn't worry.
2018-03-30T12:13:09 < PaulFertser> (trying to build stm32plus now)
2018-03-30T12:13:18 < Haohmaru> it returns 3 paths
2018-03-30T12:13:50 < PaulFertser> Haohmaru: yes, that's what your IDE needs to know
2018-03-30T12:15:08 < Haohmaru> cuz it currently thinks cstdint is this one: /usr/include/newlib/c++/5.4.1/cstdint
2018-03-30T12:16:56 < stvn> http://www2.keil.com/mdk5/
2018-03-30T12:17:52 < PaulFertser> Haohmaru: arm-none-eabi-cpp -v -xc++
2018-03-30T12:19:04 < Haohmaru> that prints a whole lot of stuff
2018-03-30T12:21:09 < PaulFertser> Haohmaru: yes, all the include directories it searches in C++ mode.
2018-03-30T12:28:59 < catphish> aandrew: there's a wire missing, glad you spotted that, VSSA should be connected to A_OUT, and VDDA floats +15v above it, hence the diode, this isn't necessary at VDDB because that floats 15v above VSSB which is connected to 0v
2018-03-30T12:29:06 < catphish> i'll fix the schematic
2018-03-30T12:33:55 < PaulFertser> Haohmaru: (stm32plus) scons mode=debug mcu=f1hd hse=8000000 builds all the library and plenty of examples (fails on fatfs one)

2018-03-30T15:44:29 < kakimir> weak!
2018-03-30T15:44:55 < kakimir> but sufficient I guess
2018-03-30T15:45:02 < dongs> the 22uA is strictly from 470k/47k divider i think

2018-03-30T15:45:10 < kakimir> most likelly
2018-03-30T15:45:22 < dongs> and kinda high Iq at no load is due to it workign in pulse skipping mode
2018-03-30T15:45:25 < kakimir> if you use such low resistance resistors
2018-03-30T15:45:34 < kakimir> mine goes into multiple megaohms

2018-03-30T15:50:37 < dongs> kakimir: excess whats, pcbs?
2018-03-30T15:50:42 < kakimir> yes
2018-03-30T15:52:00 < kakimir> does it balance btw?
2018-03-30T15:52:12 < kakimir> I see resistor + cap per cell
2018-03-30T15:52:55 < kakimir> if I see correctly it's 1k

2018-03-30T15:53:08 < kakimir> so probs just series resistor for good measure
2018-03-30T15:53:31 < dongs> no the cell shit is just for doing uvlo with that chip. i made both ways, a resistor divider or cutoff by that BQ thing
2018-03-30T15:54:02 < dongs> the thermal board is one wihtout BQ mounted, just cutoff below 11.2V by divider
2018-03-30T15:54:27 < kakimir> hmm
2018-03-30T15:54:32 < dongs> i dont have an easy way to test lipo cutoff, i guess i could put an almost-dead battery on there and draw some current from output
2018-03-30T15:54:36 < kakimir> I still need something to balance shiet
2018-03-30T15:54:42 < kakimir> good balancing shiet
2018-03-30T15:54:52 < kakimir> if I charge lipos with let's say MPPT
2018-03-30T15:57:08 < kakimir> or replace lead acid in glider with life

2018-03-30T16:04:26 < kakimir> "NOT OPENSORES"
2018-03-30T16:04:38 < kakimir> definitelly dongs made
2018-03-30T16:04:43 < dongs> kakimir: because i actually spent time to make the fucking thing
2018-03-30T16:04:55 < kakimir> is it a buffer?
2018-03-30T16:04:57 < dongs> unlike the opensores faggot who made it ugly, nonsymmetrical and fucking autorouted
2018-03-30T16:05:05 < dongs> yeah its literally just 3.3V>5V buffer

2018-03-30T16:06:52 < dongs> ya?
2018-03-30T16:07:06 < kakimir> I see dongs
2018-03-30T16:07:07 < englishman> yeah on the lil pecker
2018-03-30T16:07:12 < kakimir> what you use that buffer for?
2018-03-30T16:07:19 < englishman> the motor pylons and wing spar were pcbs
2018-03-30T16:07:24 < dongs> nice
2018-03-30T16:07:29 < dongs> yea, makes sense
2018-03-30T16:07:49 < dongs> kakimir: what buffer, the pcb? its for the led display shit
2018-03-30T16:07:50 < englishman> also simple power distribution

2018-03-30T16:08:44 < dongs> i had this rageberry in teh drawer for liek 3 years
2018-03-30T16:08:46 < dongs> unused
2018-03-30T16:09:04 < kakimir> I still have 2 totally unused ones
2018-03-30T16:09:18 < kakimir> my pi3 is used as wireless router atm.
2018-03-30T16:09:23 < dongs> stress-ng only increased pi consumption by like 250mA
2018-03-30T16:09:35 < dongs> ~240 to ~420-560
2018-03-30T16:10:00 < kakimir> you need to utilize gpu too maybe
2018-03-30T16:10:21 < kakimir> or have benchmark that uses also a lot of memory access
2018-03-30T16:10:40 < kakimir> but do you utilize gpu anyway?

2018-03-30T16:49:26 < Fizz> Well the overriding issue that we're having is that our device is subject to noise. When LED Data is transferred through DMA, we get a massive amount of noise on our sensor samples. We also get a lot of noise if we run our device on a usb hub.

2018-03-30T16:50:30 < dongs> isnt this literally like
2018-03-30T16:50:32 < dongs> 2 lines of VHDL
2018-03-30T16:50:35 < Fizz> basically there's load cells connected to boards that amplify between 0-5v, and that is then sampled by the onboard stm32 adc
2018-03-30T16:50:42 < kakimir> dongs, hello world VHDL
2018-03-30T16:51:01 < dongs> https://startingelectronics.org/software/VHDL-CPLD-course/tut19-up-down-counter/
2018-03-30T16:51:30 < dongs> Fizz: you shoudl do some homework first and isolate the problem to being sofwware, or hardware, or both
2018-03-30T16:51:51 < kakimir> hardware most likelly
2018-03-30T16:52:31 < kakimir> if you can share information about the hardware we can spot the most obivious reasons Fizz
2018-03-30T16:52:40 < kakimir> for the noise
2018-03-30T16:52:54 < dongs> you could erase STM and measure outputs of load cell amps and shit
2018-03-30T16:53:01 < dongs> stick scope in places and see what it looks like
2018-03-30T16:53:44 < Fizz> yeah, it's a slightly complicated project. the requirement is 1kHz sampling of 36 sensors
2018-03-30T16:54:00 < dongs> how are they multiplexed?
2018-03-30T16:54:01 < Fizz> I'd love it if we could just use a standard HX711 or whatever the standard is, but because of the high speed, that's why we have to do so much ustom stuff.
2018-03-30T16:54:37 < Fizz> Multiplexed with an external analog multiplexer IC
2018-03-30T16:55:06 < dongs> is it all going to a single adc? or like few in parallel after multiplex
2018-03-30T16:55:15 < Fizz> just the one ADC.
2018-03-30T16:55:25 < Fizz> the ADC takes 1uS for a sample, which gives us plenty of time
2018-03-30T16:55:26 < englishman> Fizz what country are you in
2018-03-30T16:55:27 < dongs> thats kinda shitty
2018-03-30T16:55:29 < Fizz> UK
2018-03-30T16:55:56 < Fizz> you reckon, dongs?
2018-03-30T16:55:57 < kakimir> pay Laurenceb_ to fix it
2018-03-30T16:55:58 < dongs> englishman provides top of the line engineering services
2018-03-30T16:55:58 < englishman> il do your project for 5k gbp if you also get manufacturing done thru me and design time is not more than 80 hours (2 weeks)
2018-03-30T16:55:59 < BrainDamage> splitting the thing over multiple adcs would've significantly relaxed the requirements on the mux
2018-03-30T16:56:21 < kakimir> He is an ADC specialist Fizz
2018-03-30T16:56:36 < dongs> Fizz: i depending what stm part, there's up to 3 ADCs you can sample in parallel
2018-03-30T16:56:39 < dongs> (and dma)
2018-03-30T16:56:48  * Haohmaru . o ( red flag )
2018-03-30T16:57:51 < Fizz> sorry englishman, thank you very much for the offer though. we have a supplier for manufacture
2018-03-30T16:57:58 < dongs> i recall wehn i was doing the analog hall sensor grid thing that there was timing stuff related to mux switching before ADC would get a useful value
2018-03-30T16:58:11 < englishman> np
2018-03-30T16:58:14 < kakimir> certainly there is dongs
2018-03-30T16:58:32 < kakimir> settle time or so
2018-03-30T16:58:35 < BrainDamage> yes, mux settling time, but he has to switch at 1kHz
2018-03-30T16:58:49 < dongs> 1kHz x 36, no?
2018-03-30T16:58:52 < BrainDamage> yes
2018-03-30T16:58:54 < Fizz> yep
2018-03-30T16:58:58 < BrainDamage> still doable, not cheap
2018-03-30T16:58:59 < dongs> so sounds like you fucked up
2018-03-30T16:59:01 < kakimir> how many muxes there is?
2018-03-30T16:59:10 < dongs> apparently its all going to a single adc pin
2018-03-30T16:59:20 < dongs> i guess severa CD4067s or wahetver
2018-03-30T16:59:21 < Haohmaru> doesn't that mean 36kHz sampling rate
2018-03-30T16:59:23 < Fizz> we use 2 16-1 muxes and 4 of the stm32's pins configured to act as internal mux
2018-03-30T16:59:41 < BrainDamage> Haohmaru: no, it means at least 72
2018-03-30T16:59:51 < Fizz> 36khz, sure. it's just that we build up a packet to send via HID at 1kHz
2018-03-30T16:59:57 < Haohmaru> why 72?
2018-03-30T17:00:09 < BrainDamage> oh, nvm 1kHz was the sampling rate, not the bw
2018-03-30T17:00:12 < BrainDamage> then 36
2018-03-30T17:00:21 < Haohmaru> ;]
2018-03-30T17:00:39 < Haohmaru> the poor adc
2018-03-30T17:00:50 < Haohmaru> stick 36 ardweenies on this
2018-03-30T17:00:52 < BrainDamage> stm32 adc manage a MHz
2018-03-30T17:01:03 < BrainDamage> 36kHz is nothing
2018-03-30T17:01:08 < dongs> so basically 32 muxed channels going to like adc_in0 and remaining 4 to adc_in1..4 or wahtever?
2018-03-30T17:01:14 < BrainDamage> the problem is the mux
2018-03-30T17:01:15 < Fizz> yes, dongs
2018-03-30T17:02:02 < Fizz> as an aside mention, the sensor readings directly going to adc_in1-4 are much more prone to noise than the external multiplexed ones.

2018-03-30T17:02:43 < englishman> what's the reason for not using external adcs?
2018-03-30T17:02:44 < Laurenceb__> if u are using USB just make multiple sensors and sync to USB frames

2018-03-30T17:13:26 < dongs> Fizz: have you looked at the mux, adc inputs with a scope to see what makes the noise?
2018-03-30T17:13:55 < dongs> also there are different sampling length or whatever on ADC that are configurable
2018-03-30T17:14:17 < dongs> huge doing going up

2018-03-30T17:14:32 < kakimir> you can probs use some clock output, GPIO pulse anything to trigger the scope
2018-03-30T17:14:43 < kakimir> or mux signaling

2018-03-30T17:45:57 < Laurenceb__> you know I'm beginning to think /pol/ was right
2018-03-30T17:47:09 < aandrew> 36kHz sampling rate is nothing on stm32
2018-03-30T17:47:29 < Laurenceb__> yeah
2018-03-30T17:48:34 < aandrew> my boards are in mfg now, but when I assemble them it's gonna be 3 STM32 ADCs simultaneously sampling at fmax (3Msps)
2018-03-30T17:48:39 < aandrew> hopefully it works. :-)
2018-03-30T17:49:47 < aandrew> 3 ADCs in f746, starting the sampling off of timer event, then starting next sample immediately after previous finishes
2018-03-30T17:50:19 < aandrew> idea is to measure volts/current through an led across its entire 100us or so on time to determine power delivered to led
2018-03-30T17:51:29 < aandrew> third ADC was measuring external photodiode
2018-03-30T17:51:55 < Cracki_> Laurenceb__, pol is always right, but anyway, soros keeps popping up in interesting places...
2018-03-30T17:53:41 < aandrew> what was pol saying about it
2018-03-30T17:58:23 < Haohmaru> will i get some kind of compiler/linker error if i have global scope objects with constructors but my startup code doesn't have the right stuff for those to work?
2018-03-30T17:58:32 < Haohmaru> ..or will i get an .elf anyway
2018-03-30T18:05:30 < Cracki_> guessing you'll get the elf, but the code will think the objects are initialized when they weren't?
2018-03-30T18:05:55 < Cracki_> are you sure "missing startup code" is the issue?
2018-03-30T18:06:38 < Cracki_> it would be funny if a compiler didn't take care of properly calling constructors of global objects
2018-03-30T18:07:12 < invzim> I think my standard 10uf is going 1206->0805
2018-03-30T18:07:12 < Haohmaru> no i'm just trying to make sense of this thing.. there are all kinds of example "start codes" in many flavors, asm, C, C++ and different information here and there, and i don't know what to do
2018-03-30T18:08:03 < Haohmaru> i don't have a chip yet, so i'm just trying to build something
2018-03-30T18:08:05 < Cracki_> gcc, right?
2018-03-30T18:08:09 < Haohmaru> yes
2018-03-30T18:08:16 < Cracki_> figure out what it calls the init sections
2018-03-30T18:08:30 < Cracki_> coming from atmel, they might be .init0..9
2018-03-30T18:08:45 < Haohmaru> i found this: /usr/share/doc/gcc-arm-none-eabi/examples/startup/startup_ARMCM4.S
2018-03-30T18:08:56 < Haohmaru> together with "gcc.ld" in almost the same place
2018-03-30T18:09:02 < PaulFertser> Haohmaru: newlib has startup code that does the right thing, probably you should just use that.
2018-03-30T18:09:08 < Cracki_> well, have you tested if this is really a problem, or whether it just works?
2018-03-30T18:09:49 < branjb> guys guess what
2018-03-30T18:09:50 < branjb> https://www.youtube.com/watch?v=kfVsfOSbJY0
2018-03-30T18:10:10 < Haohmaru> PaulFertser, does that mean that if i already got "libstdc++_nano.a" being used by the linker - i don't need to have any startup/asm/ld stuff?
2018-03-30T18:10:53 < Haohmaru> Cracki_, i can't test, i don't have a chip.. no .elf yet either
2018-03-30T18:11:15 < PaulFertser> Haohmaru: ld stuff you might need, to set proper size for SRAM and flash regions. Regarding startup, just do not use -nostartfiles option. You can compile a project and look at the assembly listing...
2018-03-30T18:11:38 < Haohmaru> assembly :~(
2018-03-30T18:11:58 < PaulFertser> Microcontrollers :~/
2018-03-30T18:12:06 < Haohmaru> i don't use -nostartfiles
2018-03-30T18:12:24 < Haohmaru> but i have stuff like nosys.specs (i don't even know what this is)
2018-03-30T18:12:41  * Haohmaru stole compiler settings from random makefiles
2018-03-30T18:12:58 < PaulFertser> nosys.specs is fine, it provides minimal syscalls
2018-03-30T18:13:20 < Haohmaru> so gcc.ld might be enough?
2018-03-30T18:13:48 < Haohmaru> the readme there told me that i will have to adjust flash/ram size (but not how to do so)
2018-03-30T18:13:52 < PaulFertser> ld scripts are target-specific as they need to know what maps where.
2018-03-30T18:13:59 < Haohmaru> oh
2018-03-30T18:14:17 < Haohmaru> so, the ld script from st then?
2018-03-30T18:14:32 < Haohmaru> STM32F446RCTx_FLASH.ld <- this one
2018-03-30T18:15:06 < Haohmaru> libstdc++_nano.a is "newlib" right?
2018-03-30T18:15:19 < PaulFertser> Probably newlib-nano
2018-03-30T18:15:32 < Haohmaru> nano, right
2018-03-30T18:15:49 < Haohmaru> so just these two things will be enough?
2018-03-30T18:16:33 < PaulFertser> You shouldn't be specifying libraries in Makefile, instead --specs=newlib-nano.specs should take care of linking.

2018-03-30T18:18:44 < PaulFertser> Haohmaru: looks sane
2018-03-30T18:18:48 < Haohmaru> should that be newlib-nano.specs?
2018-03-30T18:19:48 < Haohmaru> ooh, sh*t, i got an .elf now
2018-03-30T18:19:58 < Haohmaru> but still those nasty linker warnings
2018-03-30T18:21:01 < Haohmaru> is there anything specific that i should know if i intend to write a custom bootloader?
2018-03-30T18:21:25 < Haohmaru> like, anything that needs to happen in these start-up codes and/or linker scripts?
2018-03-30T18:22:33 < PaulFertser> Haohmaru: what linker warnings?

2018-03-30T18:25:53 < Haohmaru> or was it from cubeF4
2018-03-30T18:25:54 < PaulFertser> Yes, so STM32F446RCTx_FLASH.ld is wrong there. You're using newlib's startup so you need a matching ld script.
2018-03-30T18:26:44 < Haohmaru> but.. the ld script has to be chip-specific, somehow i don't expect newlib to come with a ton of ld scripts
2018-03-30T18:26:58 < Haohmaru> where do i get that from?

2018-03-30T18:30:45 < PaulFertser> Haohmaru: see how it uses ENTRY(_start) and your script apparently has ENTRY(Reset_Handler)

2018-03-30T19:04:57 < Thorn> do I understand correctly that ice40 have no signal tap equivalent?
2018-03-30T19:07:36 < aandrew> it is a small fpga, I doubt it does

2018-03-30T19:31:42 < PaulFertser> antto: I personally was using the scripts as they came with the library, and the startup included in the library. I think it should be possible to use newlib directly but I can't provide you with exact instructions, it requires digging...

2018-03-30T21:07:31 < zyp> when I can't, there's plenty of fast chargers around
2018-03-30T21:07:51 < zyp> I don't really have any statistics on exactly what percentage I charge at home
2018-03-30T21:08:47 < englishman> does your work let you steal their power?
2018-03-30T21:09:42 < englishman> your car is used mostly locally / for commuting?
2018-03-30T21:10:26 < zyp> my work is only a few kilometers from home, so there's not really much point in charging there
2018-03-30T21:11:02 < englishman> if it was free to charge at work, would you use your car more?
2018-03-30T21:11:29 < zyp> no, it makes no practical difference
2018-03-30T21:11:54 < englishman> the charging cost is low anyway?

2018-03-30T21:15:41 < englishman> you just have to find somewhere halfway to sit for a few hours and recharge?
2018-03-30T21:16:28 < zyp> charging takes about 20 minutes
2018-03-30T21:16:40 < zyp> to 80%
2018-03-30T21:17:07 < englishman> Really
2018-03-30T21:17:23 < zyp> after 80% it reduces charging power to less than half, and it's priced per minute, so it doesn't make sense to charge further than 80%
2018-03-30T21:17:26 < Laurenceb__> In the Czech Republic and Slovakia, a tradition of spanking or whipping is carried out on Easter Monday. In the morning, men spank women with a special handmade whip called a pomlázka (in Czech) or korbáč (in Slovak), in eastern regions of former Czechoslovakia Moravia and Slovakia they also throw cold water on them.
2018-03-30T21:17:36 < englishman> How common are charging stations? Do you reference a map?
2018-03-30T21:19:14 < zyp> there's a political goal to have no stretches longer than 50km between charging stations along major roads, they've already fulfilled those in most of the country
2018-03-30T21:20:09 < zyp> there's two major operators of chargers, and they both have map apps with live status and everything
2018-03-30T21:21:18 < englishman> sounds convenient.
2018-03-30T21:21:21 < zyp> ref. https://map.chargedrive.com/ for one of them
2018-03-30T21:23:44 < zyp> by default it'll show both fast chargers and 22kW «semi-fast» AC outlets
2018-03-30T21:23:59 < zyp> switch the filter to only show CCS to see the chargers relevant for my car
2018-03-30T21:28:29 < englishman> isn't there a limited number of times you can fast-charge? It's 180 or something on the tesla
2018-03-30T21:30:41 < zyp> bullshit
2018-03-30T21:30:46 < emeb> bummer - no chargers up at Andenes. No driving to visit the folks.
2018-03-30T21:31:01 < zyp> emeb, didn't stop me :)

2018-03-30T21:33:43 < BrainDamage> charging problem solved
2018-03-30T21:33:50 < zyp> emeb, slow-charging at a 3.7kW-outlet only takes 8 hours or so
2018-03-30T21:34:51 < zyp> there were enough fast chargers to get me 100km away from Andenes, and I arrived there after midnight anyway, so I just stayed the night
2018-03-30T21:35:18 < emeb> not bad
2018-03-30T21:35:21 < englishman> why did you choose golf over leaf?
2018-03-30T21:36:41 < emeb> well, cool thing about electric is that if you can find an outlet you can charge and there are more outlets than gas stations.
2018-03-30T21:36:51 < zyp> 4000km behind the wheel of my friends 2015 polo in summer 2015 convinced me that VW makes cars that are comfortable to drive
2018-03-30T21:37:56 < emeb> zyp: if you can't find a 20 outlet can you still charge at an even lower rate?
2018-03-30T21:38:02 < emeb> 20A
2018-03-30T21:38:08 < zyp> remember, I'm in 230V land
2018-03-30T21:38:10 < englishman> as the owner of 15+ VW's, I agree
2018-03-30T21:38:32 < zyp> max power of the onboard charger is 3.7kW at 230V 16A
2018-03-30T21:38:39 < upgrdman> fest, hmm. "(l)gpl" so ya
2018-03-30T21:38:43 < upgrdman> but still, wtf
2018-03-30T21:38:55 < emeb> right. Is 16A service pretty much the standard then?
2018-03-30T21:39:04 < zyp> but regulations and shit limits draw to max 10A from standard outlets
2018-03-30T21:39:22 < zyp> so the included cable is adjustable from 6A to 10A
2018-03-30T21:39:29 < emeb> excellent
2018-03-30T21:39:41 < zyp> at home I have a proper 16A EVSE
2018-03-30T21:40:15 < emeb> so if you're visiting Aunt Hilda out in the sticks and all she has is a 10A you can still charge, just a bit slower.
2018-03-30T21:41:01 < zyp> yeah, I'm now at an airbnb in Bergen, charging at 10A from an extension cord the host provided
2018-03-30T21:41:36 < fest> upgrdman: that's not a limitation of qtcreator, but the qt library. But you can make closed source stuff with it, you just can't link the stuff statically against qt library
2018-03-30T21:41:40 < zyp> so it'll be full tomorrow morning, using like $2-3 of electricity

2018-03-30T21:42:37 < englishman> but the 120km range is a bit of a turnoff

2018-03-30T21:43:00 < emeb> so electric is still cheaper.
2018-03-30T21:43:16 < upgrdman> fest, hmm ok
2018-03-30T21:43:19 < fest> The idea is: your end-users need to be able to replace the qt version. So you either release your sources, or link against qt dynamically, so end users can swap out dll/so files
2018-03-30T21:44:05 < upgrdman> ya
2018-03-30T21:44:39 < zyp> I have an impression that old leafs seems to be a bit more shitty in terms of both range and charging speed than my car, so YMMV
2018-03-30T21:44:47 < englishman> yeah that is probably why they are cheap.

2018-03-30T21:45:05 < englishman> i gues 120kW is pretty fast charging
2018-03-30T21:45:53 < zyp> well, consider this, teslas have three times the battery capacity, so naturally the same C-rating requires three times the power :)
2018-03-30T21:46:08 < zyp> my car fast charges at a bit over 40kW
2018-03-30T21:46:22 < zyp> tops out at 42kW or so, IME
2018-03-30T21:46:42 < englishman> 26.5 kWh
2018-03-30T21:46:45 < antto> that's so many watts

2018-03-30T21:50:07 < zyp> the current i3 has a larger battery than mine
2018-03-30T21:50:10 < englishman> oh 18kWh, not as small as i thought
2018-03-30T21:50:20 < zyp> 30-something in the current model
2018-03-30T21:50:26 < englishman> yes, getting up there
2018-03-30T21:50:29 < upgrdman> i wonder if chevy makes good cars these days. they used to be total shit
2018-03-30T21:50:39 < englishman> the chevy volt is extremely popular here
2018-03-30T21:50:51 < zyp> dunno
2018-03-30T21:50:55 < englishman> that doesnt mean they are good tho :)
2018-03-30T21:51:12 < zyp> the chevy bolt (or opel ampera-e as it's sold as here) seems kinda shit
2018-03-30T21:51:40 < zyp> though, most of the criticism seems to be focused on not being able to fill the demand
2018-03-30T21:52:07 < zyp> but they also seems to be shitty wrt. charging, oddly slow fast charging
2018-03-30T21:52:20 < upgrdman> how slow?
2018-03-30T21:52:29 < englishman> leaf supports 44kW chademo apparently
2018-03-30T21:52:29 < upgrdman> i mean in most cases, you can just charge overnight
2018-03-30T21:52:40 < zyp> not sure, I only know hearsay really
2018-03-30T21:52:44 < upgrdman> k
2018-03-30T21:52:51 < zyp> I said fast charging
2018-03-30T21:53:00 < zyp> overnight charging should be fine in any case
2018-03-30T21:53:14 < zyp> englishman, yes
2018-03-30T21:53:24 < englishman> what is the golf charge rate? sounds like it would have to be 120kW ish to charge in 20min
2018-03-30T21:53:34 < englishman> no, less, but not 44kW
2018-03-30T21:53:50 < zyp> like I said earlier, my car tops out around 42kW as far as I've seen
2018-03-30T21:53:56 < englishman> oh, missed that sorry
2018-03-30T21:53:57 < englishman> hmm
2018-03-30T21:54:38 < zyp> I believe it runs constant-current up to around 80%, and since the voltage is rising a little over that range, so does power
2018-03-30T21:54:48 < zyp> and then it halves current as soon as it hits 80%
2018-03-30T21:55:28 < zyp> englishman, how long is your commute?
2018-03-30T21:55:35 < englishman> ooh, before 2016 chademo was optional
2018-03-30T21:55:40 < englishman> 19km i think?
2018-03-30T21:55:55 < englishman> no, 24km
2018-03-30T21:56:08 -!- gnom [~aleksande@178.150.7.153] has joined ##stm32
2018-03-30T21:56:25 < zyp> 24km in each direction should be totally doable in a leaf no matter how old and shitty it is
2018-03-30T21:56:30 < englishman> yes for sure
2018-03-30T21:56:45 < englishman> but the question is if i get rid of the volvo
2018-03-30T21:56:49 < zyp> question is if it's economically justified
2018-03-30T21:57:18 < zyp> I assume you have a much lower difference between electricity costs and gas costs compared to here
2018-03-30T21:58:04 < Steffanx> A nissan leaf 15k$ WUT? What leaf is that englishman?
2018-03-30T21:58:14 < englishman> https://www.lespac.com/quebec/vehicules-autos/2013-nissan-leaf-sv-23-310-km_48658974D0.jsa
2018-03-30T21:58:19 < englishman> thats at a nissan dealer too
2018-03-30T21:58:24 < englishman> SV is the top trim model
2018-03-30T21:58:28 < Steffanx> oh 2nd hand?
2018-03-30T21:58:33 < englishman> yes
2018-03-30T21:58:33 < zyp> naturally
2018-03-30T21:58:41 < zyp> they are that cheap here too
2018-03-30T21:58:47 < Steffanx> ooh, explains a lot.
2018-03-30T21:59:28 < englishman> this weekend that price rises by $4k
2018-03-30T22:00:40 < zyp> https://www.finn.no/car/used/ad.html?finnkode=116448513 <- this seems to be the cheapest on the market here now, $10k-ish
2018-03-30T22:00:58 < englishman> 140k km!
2018-03-30T22:01:03 < zyp> https://www.finn.no/car/used/ad.html?finnkode=110817261 <- another one
2018-03-30T22:01:45 < zyp> well, yeah, the cheapest are naturally the oldest with the highest mileage
2018-03-30T22:02:55 < zyp> englishman, is $15k before or after that 4k rebate?
2018-03-30T22:03:21 < Steffanx> Im not one to say a car is ugly, but that older model leaf is getting there :P
2018-03-30T22:03:21 < englishman> it doesnt say in the ad, but other dealers are posting the price including the rebate, so i assume this one includes the rebate too
2018-03-30T22:03:45 < zyp> Steffanx, well, yeah, they aren't pretty :p
2018-03-30T22:04:04 < zyp> the new 2018 leafs looks nice though
2018-03-30T22:04:23 < Steffanx> Yeah, indeed.
2018-03-30T22:04:33 < zyp> my first thought when I saw one was «woah, nissan made a leaf that looks good»
2018-03-30T22:04:51 < zyp> actually saw quite a few of them today
2018-03-30T22:07:12 < Steffanx> Hardly any EVs here. Especially not in this region. So even 2nd hand they are pretty pricey.
2018-03-30T22:07:24 < zyp> aww
2018-03-30T22:07:46 < zyp> come visit norway, you can have a ride in mine :)
2018-03-30T22:09:07 < zyp> bring Tectu too
2018-03-30T22:10:28 < Steffanx> Hah, perhaps.
2018-03-30T22:11:21 < Steffanx> Important question here is: Does your wife know what irc is and especially what ##stm32 is?
2018-03-30T22:12:13 < zyp> vaguely
2018-03-30T22:12:24 < zyp> you're «the dutch guy»
2018-03-30T22:12:31 < englishman> haha
2018-03-30T22:12:32 < Rickta59> won't the batteries on a 2013 be on the end of their life?
2018-03-30T22:13:02 < zyp> Rickta59, modern EVs are usually sold with a 8 year battery warranty, so they shouldn't be
2018-03-30T22:13:04 < englishman> although they only have an 8 year warranty, i think with only 23k km they should be alright
2018-03-30T22:13:23 < englishman> there is some self-diagnostic that reports battery health as well
2018-03-30T22:13:51 < Rickta59> but doesn't it drop to like 80% as you get towards the end of their life?
2018-03-30T22:14:42 < Rickta59> heh .. you are canadian so I guess you are used to that (USD vs CAD) :)
2018-03-30T22:15:15 < Steffanx> zyp: after visiting Tectu i know it's important for the host to explain irc and ##stm32 to their friends/family first. Otherwise it'll be quite shock.
2018-03-30T22:15:25 < Steffanx> *quite a shock
2018-03-30T22:15:47 < englishman> tectu has friends?
2018-03-30T22:16:06 < jpa-> zyp caused no shock here :)
2018-03-30T22:16:25 < jpa-> even though i have no idea how i could explain ##stm32 to anyone
2018-03-30T22:16:30 < zyp> haha
2018-03-30T22:16:30 < Steffanx> Did you discuss ##stm32?
2018-03-30T22:16:48 < jpa-> irc is simple enough, "notepad that talks back to you"
2018-03-30T22:17:07 < Rickta59> just call it "modern" AOL chat
2018-03-30T22:17:17 < jpa-> no, i just said "some norwegian dude from irc will drop by"
2018-03-30T22:18:30 < jpa-> at this point, i think it is more socially acceptable to be on 4chan than to be on ##stm32
2018-03-30T22:19:03 < Steffanx> but how do you explain to someone you are going to meet someone and you dont even know his real name? Just his online nickname :D
2018-03-30T22:19:25 < Steffanx> Which was in this case and interesting nickname.
2018-03-30T22:19:30 < jpa-> ah, but i knew zyp's name, just couldn't pronounce it
2018-03-30T22:19:38 < englishman> https://insideevs.com/nissan-introduces-refabricated-batteries-for-older-leaf-in-japan-from-new-4r-plant/
2018-03-30T22:19:39 < englishman> hmm
2018-03-30T22:19:43 < zyp> Steffanx, I know your name though
2018-03-30T22:19:44 < englishman> not too expensive
2018-03-30T22:19:49 < jpa-> and if it was you, i'd just call you Steffan Naffets
2018-03-30T22:20:05 < Steffanx> That'll work.
2018-03-30T22:20:59 < jadew> quick poll: who's a communist?
2018-03-30T22:21:06 < jadew> (here)
2018-03-30T22:21:07 < Steffanx> And i could always send waffles first. Then it would be "The waffle guy". I could live with that.
2018-03-30T22:21:09 < zyp> jadew
2018-03-30T22:21:13 < jadew> I'm not
2018-03-30T22:21:22 < jadew> just say "I am" if you are
2018-03-30T22:21:25 < zyp> I thought this was a poll, so I vote on you
2018-03-30T22:21:35 < jpa-> i nominate r2commie
2018-03-30T22:21:43 < jadew> I don't think he's a commie either
2018-03-30T22:21:56 < englishman> wtf, nissan leaf nav requires a 2G connection
2018-03-30T22:22:03 < jpa-> what's a communist anyway, some kind of boogeyman?
2018-03-30T22:22:13 < jadew> jpa-, yes
2018-03-30T22:22:22 < Laurenceb__> jpa- confirmed as stalin
2018-03-30T22:22:30 < jadew> I went to politics earlier and ended up spending the whole day discussing with the people there
2018-03-30T22:22:35 < jadew> turns out most of them are communists
2018-03-30T22:22:39 < Laurenceb__> >going to politics
2018-03-30T22:22:41 < jadew> and in communist parties
2018-03-30T22:22:46 < Laurenceb__> >anywhere on the internets
2018-03-30T22:22:46 < jadew> ##politics
2018-03-30T22:23:05 < Steffanx> poor you.
2018-03-30T22:23:08 < jadew> anyway, point is that I was surprised to learn that there are even communist parties in some european countries
2018-03-30T22:23:12 < jadew> and they belong to them
2018-03-30T22:23:26 < Steffanx> Surprised?
2018-03-30T22:23:28 < jadew> it's just surprising to me
2018-03-30T22:23:29 < jadew> yeah
2018-03-30T22:23:35 < Laurenceb__> shrug its their choice
2018-03-30T22:23:35 < jadew> and I wanted to do a reality check
2018-03-30T22:24:31 < Steffanx> reality check.. ##stm32. :P
2018-03-30T22:24:44 < jadew> heh
2018-03-30T22:24:56 < zyp> Steffanx, I think the best part is how I've both met dongs, visited his place and done thousands of dollars of business with him, but still don't really know his real name
2018-03-30T22:25:05 < jadew> Steffanx, seems more like a safe space now
2018-03-30T22:25:22 < Steffanx> and you tell your wife you do business with "dongs", zyp?
2018-03-30T22:25:49 < jpa-> we have two communist parties here in finland, because they couldn't agree on whether they like marx or lenin more
2018-03-30T22:26:01 < zyp> Steffanx, I might have mentioned his nickname, yes
2018-03-30T22:26:11 < jadew> jpa-, that's insane...
2018-03-30T22:26:13 < Steffanx> must have been an interesting talk.
2018-03-30T22:26:40 < jadew> in here, being called a communist is an insult
2018-03-30T22:26:55 < zyp> Steffanx, nah, I don't think she was very interested :p
2018-03-30T22:27:07 < Laurenceb__> Interesting fact about political parties, they are actually I don't know anything interesting about politics
2018-03-30T22:27:37 < Steffanx>  /pol/ right?
2018-03-30T22:28:03 < jadew> Laurenceb__, well, it looks like the commies are taking over, so that's interesting for sure
2018-03-30T22:28:22 < englishman> wifeishman did ask why i named my cat lil'dongs
2018-03-30T22:28:22 < jadew> now you're in danger of being kicked out of the UK, soon you may not be allowed to leave
2018-03-30T22:29:33 < jadew> englishman, hah, that's its actual name?
2018-03-30T22:29:37 < englishman> yes
2018-03-30T22:29:46 < jadew> funny
2018-03-30T22:32:05 < Steffanx> :P

2018-03-31T01:03:16 < Laurenceb__> The name England originates from Bangladesh, 20,000 years ago Bangladesh was called b'Angl-a-desh, the prefix B was not used much and thus becale Angle-desh or land of the Aryan-desh, the Aryans migrated from Bangladesh to England and called themselves Angles, thus derieved the name Angles-land or Eng-land. This became England eventually.
2018-03-31T01:03:32 < stvn> good morning
2018-03-31T01:03:43 < Laurenceb__> sup
2018-03-31T01:03:53 < Laurenceb__> today I am learning about muh heritage
2018-03-31T01:04:02 < stvn> same, there is no heritage
2018-03-31T01:04:07 < upgrdman> you must be so proud
2018-03-31T01:06:56 < stvn> i blew it up
2018-03-31T01:17:59 < upgrdman> god damn, a full qt creator install is >12GB
2018-03-31T01:18:10 < upgrdman> almost as bad as an FPGA toolchain ffs
2018-03-31T01:18:42 < stvn> such as
2018-03-31T01:18:56 < upgrdman> well xilinx ise is ~15GB iirc
2018-03-31T01:19:06 < upgrdman> and lattice diamond is ~7GB
2018-03-31T01:19:16 < upgrdman> at least diamond is fast
2018-03-31T01:19:35 < stvn> i don't remember diamond being that big
2018-03-31T01:19:41 < upgrdman> new versions are
2018-03-31T01:19:43 < upgrdman> 3.9
2018-03-31T01:19:46 < stvn> hah
2018-03-31T01:19:52 < stvn> i wonder about altera cuntus
2018-03-31T01:19:58 < BrainDamage> quartus 2 back when i used it 3 years ago was 12
2018-03-31T01:19:58 < upgrdman> 3.6 was ~4GB iirc
2018-03-31T01:21:12 < upgrdman> side note: if i aim a fan at the back of my surface pro 4, i gain ~600MHz
2018-03-31T01:21:32 < upgrdman> (well, it stops throttling down 600MHz)
2018-03-31T01:21:51 < BrainDamage> does it have the scorched balls effect?
2018-03-31T01:22:11 < upgrdman> nah, the cpu is near the top-right of the "tablet"
2018-03-31T01:22:17 < upgrdman> so balls dont get too hot
2018-03-31T01:22:26 < upgrdman> but i ~never use it on my lap anyway
2018-03-31T01:26:53 < Steffanx> Isnt it more "God damn, a full Qt install is > 12GB" ? As you install Qt to get the Creator?
2018-03-31T01:27:10 < Steffanx> btw a FULL install of Qt is 532.25 GB :P
2018-03-31T01:27:22 < upgrdman> orly?
2018-03-31T01:27:56 < Steffanx> Ya really.
2018-03-31T01:28:19 < upgrdman> oh. i downloaded the "open source" version. are you talking about the commerical one?
2018-03-31T01:28:31 < upgrdman> i guess there's assloads more if you pay for it
2018-03-31T01:28:54 < Steffanx> No, i just selected all options. Which gets you like 20 different versions of Qt.
2018-03-31T01:29:02 < upgrdman> lol
2018-03-31T01:29:49 < Steffanx> And yes it was the open sores installer.

2018-03-31T02:06:28 < Laurenceb__> tfw there is literally no purpose for muh GUI
2018-03-31T02:06:57 < Laurenceb__> just udev + alsa and a simple config tool to write the virtual device definitions
2018-03-31T02:07:20 < Laurenceb__> then virtual device will appear in audacity when u have the right set of sensors plugged in
2018-03-31T02:08:10 < stvn> windows

2018-03-31T13:39:16 < rajkosto> how do i get them datasheets and reference schematics yo
2018-03-31T13:39:24 < dongs> click the link
2018-03-31T13:39:45 < rajkosto> huh where
2018-03-31T13:40:00 < dongs> you email for datasheetz, and send them 250bux for 10 samples/evalboard
2018-03-31T13:40:16 < rajkosto> aint nobody got time for that
2018-03-31T13:40:22 < dongs> datasheet will have ref schematic and they also provide cad stuff on request
2018-03-31T13:40:23 < dongs> well yeah sure.
2018-03-31T13:40:25 < dongs> good luck.
2018-03-31T13:41:40 < rajkosto> i can at least find datasheets for the genesys ones
2018-03-31T13:41:53 < rajkosto> to see if the package/pinout will fit
2018-03-31T13:42:07 < dongs> its qfn48
2018-03-31T13:42:09 < dongs> 7x7 or wahtever
2018-03-31T13:42:23 < rajkosto> does it requir external nor
2018-03-31T13:42:29 < dongs> for what
2018-03-31T13:42:36 < dongs> are we talkign about same thing?
2018-03-31T13:42:45 < dongs> this is a USB3->sd/mmc card reader controller
2018-03-31T13:42:50 < rajkosto> the genesys ones have "firmware" that is on a nor
2018-03-31T13:42:52 < rajkosto> spi nor
2018-03-31T13:42:55 < dongs> lol no.
2018-03-31T13:43:02 < dongs> there's a 8051 with maskrom
2018-03-31T13:43:09 < dongs> doesnt need any external shit
2018-03-31T13:43:17 < rajkosto> and they also mention that they have internal xtal and regulators
2018-03-31T13:43:28 < rajkosto> but the datasheet doesnt say that connecting stuff to XI/power pins is optiona
2018-03-31T13:43:34 < dongs> i have a board with 64qfn version of the alcor
2018-03-31T13:43:44 < rajkosto> whats on it
2018-03-31T13:43:51 < dongs> ive never seen a card reader/  usb related shit that didnt require a crystal

2018-03-31T13:45:28 < dongs> yes
2018-03-31T13:45:32 < dongs> that makes total sense
2018-03-31T13:45:35 < dongs> it either takes a xtal
2018-03-31T13:45:40 < dongs> or optional 25mhz input clock
2018-03-31T13:45:44 < dongs> leaving xtal output NC

2018-03-31T13:46:13 < dongs> xtal-less if you ahve something else to make 25mhz from
2018-03-31T13:46:21 < rajkosto> :thonking:
2018-03-31T13:46:27 < rajkosto> "on chip clock source"
2018-03-31T13:46:38 < rajkosto> i think its fully xtal-less
2018-03-31T13:46:41 < rajkosto>   Support OCCS (On-Chip Clock Source) to eliminate external 25MHz crystal to save BOM cost
2018-03-31T13:49:12 < dongs> wow gl datashets havent changed
2018-03-31T13:49:17 < dongs> same format since like earlt 2000s
2018-03-31T13:49:20 < dongs> which was last i used trheir shit
2018-03-31T13:49:21 < rajkosto> its crap
2018-03-31T13:49:29 < rajkosto> doesnt tell me most things i wanna know
2018-03-31T14:05:24 < dongs> because something as a reader controller doesn't need a lot of docs
2018-03-31T14:05:32 < dongs> you're provided a schematic and sample layout
2018-03-31T14:05:36 < dongs> which you copypaste into your product and sell it
2018-03-31T14:05:46 < dongs> the reference design is already as cheap as its gonna be
2018-03-31T14:12:46 < rajkosto> yes give me that pls

2018-03-31T14:54:25 < dongs> its symmetrical.
2018-03-31T14:54:30 < rajkosto> this kicad footprint has them numbered... right to left
2018-03-31T14:54:36 < dongs> lol kikecad
2018-03-31T14:55:29 < rajkosto> https://images.sshnuke.net/2018-03-31_13-55-23.png as you can see its right to left
2018-03-31T14:56:20 < dongs> what fucking garbage net naming
2018-03-31T14:56:21 < dongs> what the fuck
2018-03-31T14:56:45 < antto> that's what happens when you don't name your nets at all
2018-03-31T14:57:10 < dongs> how can something on a conncetor like that not be named
2018-03-31T14:57:13 < rajkosto> why the hell is it right ot left though
2018-03-31T14:57:23 < dongs> its rotated??
2018-03-31T14:57:38 < rajkosto> its not, its mirrored horizontally
2018-03-31T14:57:47 < rajkosto> sane people number the top left pad 1, right ?
2018-03-31T14:57:51 < rajkosto> not the top right
2018-03-31T14:57:55 < dongs> what
2018-03-31T14:57:58 < dongs> its rotated 180
2018-03-31T14:58:18 < rajkosto> https://images.sshnuke.net/2018-03-31_13-58-14.png ok unrotated
2018-03-31T14:58:20 < rajkosto> now the bottom left pad is 1
2018-03-31T14:58:30 < dongs> yes
2018-03-31T14:58:35 < dongs> so where's the problem
2018-03-31T14:58:39 < rajkosto> is that the way to do it ?
2018-03-31T14:58:43 < rajkosto> i always made top left pad 1
2018-03-31T14:58:51 < antto> rajkosto that footprint looks like sitting on the back side of the PCB
2018-03-31T14:58:55 < dongs> no lol

2018-03-31T15:03:26 < antto> you know that the connectors meant to plug into each other don't have the same pinout numbering on the board, right?

2018-03-31T15:38:48 < dongs> lol @ family-photo
2018-03-31T15:39:02 < Tectu> dongs you remember that, don't you?
2018-03-31T15:39:19 < dongs> no
2018-03-31T15:39:23 < dongs> this is first time im seeingf it
2018-03-31T15:39:35 < Tectu> I created that like a year ago
2018-03-31T15:39:48 < Tectu> back then when Steffanx tried to "save the channel"
2018-03-31T15:39:58 < Tectu> a year later he decided to "destroy tectu's real life" instead
2018-03-31T15:40:06 < dongs> rajkosto: so many things wrong wiht that footprint
2018-03-31T15:40:06 < Tectu> he succeeded in one of those.
2018-03-31T15:40:26 < dongs> reference not in center, individually numbered mounting pads, terrible
2018-03-31T15:40:33 < dongs> and of course weird pad numbering
2018-03-31T15:40:46 < rajkosto> you said that its normal to go top right
2018-03-31T15:40:58 < dongs> then its rotated wrong way :)
2018-03-31T15:41:13 < rajkosto> that doesnt really matter
2018-03-31T15:41:17 < rajkosto> can just hit space twice
2018-03-31T15:41:47 < rajkosto> also, 0 in center gives no benefits and only downsides
2018-03-31T15:41:55 < rajkosto> when you pick up a footprint in altium your cursor is the 0
2018-03-31T15:42:06 < rajkosto> so might as well put it on a pad so that you can snap footprint to track edge easily
2018-03-31T15:42:51 < jpa-> pnp machine operator might like you more if your 0 is at center of the part, though
2018-03-31T15:43:25 < jpa-> (unless you can set that separately in altium)
2018-03-31T15:43:34 < rajkosto> dongs, https://images.sshnuke.net/2018-03-31_14-43-29.png better ?
2018-03-31T15:43:45 < antto> luckily, kicad has a convention for that
2018-03-31T15:45:03 < rajkosto> also why not individually pin the mounting connectors ?
2018-03-31T15:45:10 < rajkosto> what if you want some of them to not be connected ?
2018-03-31T15:46:02 < dongs> because i can't imagine when you ever do on a connector like that
2018-03-31T15:46:12 < dongs> i generally just name them all 0 and add a hidden pin 0 which is tied to GND
2018-03-31T15:46:15 < dongs> on the symbol
2018-03-31T15:50:47 < Steffanx> Lol you participated in that destroying just as much mr Tectu
2018-03-31T15:50:56 < dongs> the channel was dying?
2018-03-31T15:50:57 < dongs> what did i miss
2018-03-31T15:51:06 < Tectu> Steffanx, that's not how I remember it, Mr. Backstabber

2018-03-31T17:58:03 < Streaker> Medical technology hasn't advanced to the point where someone's mom can be a he
2018-03-31T17:58:22 < catphish> actually it has
2018-03-31T17:58:53 < catphish> in so much as that no medicine is required for someone who is a mother to live as a man
2018-03-31T17:59:00 < Thorn> my spartan-6 have continuity between gnd pins, so at least they're not empty packages lol

2018-03-31T17:59:09 < catphish> though i suppose they'd be a father then?
2018-03-31T17:59:11 < catphish> ugh, so confused
2018-03-31T17:59:28 < englishman> but does it have continuity between vdd and gnd

2018-03-31T18:00:33 < catphish> oh, i have an actual stm32 question
2018-03-31T18:00:34 < Streaker> Wrong chip inside?
2018-03-31T18:00:57 < antto> catphish just one? i have like, a hundred
2018-03-31T18:01:02 < Streaker> Or maybe just a lead frame with no chip
2018-03-31T18:01:53 < catphish> why does stm32cubemx thing my ADC1 has 16 inputs but ADC3 only has 4 inputs?
2018-03-31T18:02:02 < catphish> *think
2018-03-31T18:02:49 < Steffanx> because you picked a package where adc3 only has 4/
2018-03-31T18:02:50 < Steffanx> idk
2018-03-31T18:03:22 < catphish> well that's what i'm worried about, but i'm sure it's supposed to have more
2018-03-31T18:04:19 < Steffanx> so open the datasheet and check the pins?
2018-03-31T18:05:22 < catphish> just doing that now, it definitely has more, strange
2018-03-31T18:06:56 < catphish> oh, it doesn't in my chosen pin configuration, the datasheet covers multiple packages, so you're right
2018-03-31T18:07:29 < catphish> not enough pins to support the additional inputs
2018-03-31T18:07:35 < catphish> that screws up my design :(
2018-03-31T18:09:30 < antto> the datasheet conveniently rounds up
2018-03-31T18:09:55 < antto> the truth is in the small size font text

2018-03-31T18:10:23 < catphish> i just need to read the package description better :)
2018-03-31T18:10:29 < Streaker> Dont woory. The die has all the pads.  Just decap the ic with fuming nitric acid and add bond wires as needed.
2018-03-31T18:10:40 < catphish> i can fix it byb moving some other pins around :)

2018-03-31T20:35:06 < danxe> Hello, I'm trying to get ethernet working in linux on STM32f746-disco, but when driver resets ethernet dma by writing SR bit of ETH_DMABMR register to 1, it never completes (bit not cleared)
2018-03-31T20:36:50 < branjb> you're running lunix on a stm32f7?
2018-03-31T20:37:25 < danxe> yes, i am trying latest version
2018-03-31T20:37:31 < branjb> interesting
2018-03-31T20:37:33 < danxe> I've configured ethernet with this dts (https://pastebin.com/6RJfg0Mp), but I can't find out why DMA couldn't be resetted.
2018-03-31T20:39:13 < zyp> catphish, drove through that undersea tunnel yesterday like I mentioned I would
2018-03-31T20:39:30 < zyp> car was charging with 15-20 kW or so all the way down
2018-03-31T20:39:31 < catphish> zyp: cool, how'd it go
2018-03-31T20:39:37 < catphish> wow
2018-03-31T20:39:46 < zyp> only got down to 6.7 kWh/100km though

2018-03-31T21:39:22 < englishman> wow that's quite efficient
2018-03-31T21:40:39 < zyp> last time I drove that tunnel, average consumption were negative when I hit the bottom
2018-03-31T21:40:43 < zyp> but that was during summertime
2018-03-31T21:41:21 < zyp> now I used more energy for heating while driving over there, so I didn't recover as much on the way down as I already used
2018-03-31T21:41:57 < zyp> it's easy to be efficient when you're going downhill :p
2018-03-31T21:42:10 < zyp> average consumption overall yesterday was about 15 or so
2018-03-31T21:42:28 < zyp> in summer it would probably have been just below 12 for the same trip
2018-03-31T21:43:51 < englishman> still, that would mean about $1.35/100km vs $14.88/100km that i pay now
2018-03-31T21:44:07 < englishman> and no, i actually calculated that, 12.4*1.2
2018-03-31T21:46:17 < zyp> what's the math here? 12.4 l/100km and $1.2 per liter?
2018-03-31T21:46:24 < englishman> yes
2018-03-31T21:46:35 < zyp> CAD or USD?
2018-03-31T21:46:38 < englishman> all in cad
2018-03-31T21:47:16 < zyp> okay, you pay about half for gas than I do
2018-03-31T21:47:28 < zyp> how much per kWh?
2018-03-31T21:47:51 < englishman> used 9c
2018-03-31T21:48:01 < englishman> it's 8.75 or so but it will go up next year

2018-03-31T21:48:18 < englishman> if i buy a $15k car it will literally pay for itself in 110,000km
2018-03-31T21:52:02 < zyp> depends a lot on driving style and weather though
2018-03-31T21:52:42 < zyp> I usually do less than 12 on 80kph roads in summer
2018-03-31T21:53:01 < zyp> going 120 kph in winter consumes almost twice that
2018-03-31T21:55:34 < englishman> ah yes lots of those narrow 80km roads
2018-03-31T21:55:43 < englishman> my commute is mostly highway at 120km/h
2018-03-31T21:56:14 < englishman> in the summer i do spend much less on fuel though, when i use the golf tdi
2018-03-31T21:56:20 < zyp> at the distance you mentioned yesterday you should be fine either way
2018-03-31T21:56:37 < englishman> but it looks like an electric car is a decent investment if it can last a few hundred Mm
2018-03-31T21:56:46 < zyp> yeah
2018-03-31T21:57:27 < zyp> I've put 47k km or so on mine in a bit over two years
2018-03-31T21:57:44 < englishman> the $4k rebate got extended so no rush
2018-03-31T22:01:07 < zyp> I did some estimates the other day and it seems like I've made back close to half of what I've paid off on the loan so far in savings
2018-03-31T22:02:38 < zyp> I exported a list of toll roads I've passed through (EVs don't pay road tolls), and figured I've saved around 10k NOK just on road tolls
2018-03-31T22:03:29 < zyp> and compared to my old car, I probably save around 1 NOK/km in fuel
2018-03-31T22:03:32 < tpw_rules> what electric?
2018-03-31T22:03:38 < zyp> bit less when electricity comes from a fast charger
2018-03-31T22:03:46 < zyp> tpw_rules, I have an egolf
2018-03-31T22:03:48 < tpw_rules> ah ok
2018-03-31T22:03:55 < tpw_rules> what's the range on those?
2018-03-31T22:04:05 < tpw_rules> my aunt has an audi etron and it just kinda seemed silly
2018-03-31T22:04:33 < zyp> theoretical specs says 190km (NEDS)
2018-03-31T22:04:36 < tpw_rules> i mean it worked great but i wish they coulda crammed more battery in. it's not like they didn't have the space...
2018-03-31T22:04:38 < tpw_rules> oh ok, so it's a real one
2018-03-31T22:04:43 < tpw_rules> the audi is only like 60
2018-03-31T22:04:44 < zyp> in practice I've done 160km
2018-03-31T22:04:59 < zyp> well, e-tron is a hybrid, not pure EV
2018-03-31T22:05:30 < tpw_rules> it's a plugin hybrid but yes
2018-03-31T22:05:41 < tpw_rules> i still maintain there was plenty of room for batteries in that thing
2018-03-31T22:05:57 < kaa> anyone done STM32 with LFBGA100 10x10mm?
2018-03-31T22:06:07 < zyp> over here the distinction is important, hybrids don't get all the same incentives as EVs
2018-03-31T22:06:46 < tpw_rules> even if they're operating as EVs?
2018-03-31T22:07:23 < tpw_rules> kaa: 'done'?
2018-03-31T22:07:39 < tpw_rules> using a bga of that magnitude sounds kind of terrifying
2018-03-31T22:07:40 < tpw_rules> even if it's a little baby
2018-03-31T22:08:23 < kaa> it would really give some benefits
2018-03-31T22:08:32 < kaa> get rid of things like muxes
2018-03-31T22:08:33 < tpw_rules> what do you mean by use
2018-03-31T22:08:39 < tpw_rules> lay out a board with? program?
2018-03-31T22:08:55 < tpw_rules> you can get enormous QFPs
2018-03-31T22:09:13 < tpw_rules> i'm working with something that has an LQFP144
2018-03-31T22:09:14 < kaa> use in your design that is has had functional prototypes or production versions
2018-03-31T22:09:31 < tpw_rules> what exactly is your question. what do you want to know about it
2018-03-31T22:09:43 < tpw_rules> zyp: is the egolf fun?
2018-03-31T22:09:48 < kaa> what to concider
2018-03-31T22:09:50 < zyp> in norway, you pay no VAT or other registration fees when buying an EV, you're exempt from road tolls, ferry tickets and public parking fees, in addition to having access to bus lanes
2018-03-31T22:09:53 < kaa> when using such thing
2018-03-31T22:10:16 < zyp> some of the benefits are starting to disappear now, but there's still plenty left
2018-03-31T22:10:25 < tpw_rules> zyp: but that doesn't apply to a car with an engine, even if it doesn't use it? what if you bought an i3 with the range extender
2018-03-31T22:10:28 < zyp> and hybrid EVs gets none of those
2018-03-31T22:10:31 < zyp> correct
2018-03-31T22:10:44 < tpw_rules> that's lame
2018-03-31T22:10:46 < kaa> zyp, Elon Musk lovess Norway
2018-03-31T22:10:48 < tpw_rules> but i guess norway is small
2018-03-31T22:11:04 < invzim> guru's, are all sot-23 5 pin ldo's created with equal pinout?
2018-03-31T22:11:08 < zyp> i3 rex counts as a hybrid, so both VAT and registration fee is due, so it's a lot more expensive than i3 BEV, although the practical difference is small
2018-03-31T22:11:39 < tpw_rules> that's stupid
2018-03-31T22:11:44 < tpw_rules> what if you pulled out the engine and put it into your 'bev'
2018-03-31T22:12:14 < zyp> that would require reregistration, for which fees would be due
2018-03-31T22:13:05 < tpw_rules> aww
2018-03-31T22:13:16  * tpw_rules likes the US in almost only that regard
2018-03-31T22:13:22 < zyp> just like a normal car would need to be reregistered if you swap the engine for a more powerful engine
2018-03-31T22:14:32 < zyp> well, idk
2018-03-31T22:14:47 < zyp> IMO the rules here are sane enough
2018-03-31T22:14:50 < tpw_rules> yeah nobody cares in most of the US about that
2018-03-31T22:15:22 < tpw_rules> i guess the situations are pretty different
2018-03-31T22:15:37 < zyp> the line needs to be drawn somewhere, and if done improperly, it'll leave a lot of loopholes to be exploited
2018-03-31T22:16:33 < tpw_rules> what do you mean
2018-03-31T22:17:39 < tpw_rules> i think it's kind of lame when people try to enforce compliance to the original design
2018-03-31T22:17:53 < tpw_rules> make sure it's a) safe and b) within relevant emissions limits and be quiet
2018-03-31T22:18:05 < zyp> well, consider the i3 rex, it's basically a BEV with a range extender
2018-03-31T22:18:40 < zyp> now, imagine you want to give it the same incentives as the pure BEV
2018-03-31T22:18:57 < zyp> how do you formulate that, without giving it to every other hybrid car as well?
2018-03-31T22:19:22 < tpw_rules> one capable of operating on electric power alone for > 50km
2018-03-31T22:21:21 < zyp> make that rule and you'll get a bunch of carmakers making PHEVs with exactly enough batteries to hit 50km, not anything more
2018-03-31T22:21:39 < tpw_rules> or maybe one with greater than 10kWh of battery. that would also allow homebuilt vehicles
2018-03-31T22:21:40 < tpw_rules> so?
2018-03-31T22:24:22 < zyp> to be fair, PHEVs also have benefits over plain gasoline cars
2018-03-31T22:24:40 < zyp> they get decent discounts in registration fees
2018-03-31T22:26:52 < zyp> the problem with PHEVs is that emissions depends a lot on usage pattern
2018-03-31T22:27:34 < zyp> a lot of people here buy PHEVs, but never plug them in because they don't actually have to
2018-03-31T22:28:07 < zyp> and then they aren't so much better for the environment than plain gasoline cars anymore
2018-03-31T22:30:41 < Steffanx> what do you drive now that does 12/100, englishman?

2018-03-31T22:35:03 < zyp> MCUs with programmable timers
2018-03-31T22:36:14 < zyp> TI Hercules has N2HET, NXP LPC has SGPIO/SCT
2018-03-31T22:36:37 < zyp> are there any other interesting systems I should look at?

2018-03-31T22:44:11 < zyp> I wanna make pulse-patterns varying in interval, and it'd be nice if I could offload computation of the interval from the cpu
2018-03-31T22:45:01 < zyp> https://bin.jvnv.net/file/VjR0j.png <- like this
2018-03-31T22:45:08 < dale6998> hello...wanted to double check something...if my clocks are running at, say, 84MHz, does that mean if the prescaler is 0, each tick of the clock is 1/84MHz?
2018-03-31T22:45:08 < zyp> that's number of pulses vs time
2018-03-31T22:45:32 < zyp> dale6998, by clocks you mean timers?
2018-03-31T22:46:03 < dale6998> yes, that's right...timers
2018-03-31T22:46:13 < dale6998> i'm trying to see how long a process takes
2018-03-31T22:46:28 < Steffanx> Wouldnt PSoC be able to do that zyp? ( never used it, and never really looked into it, so i could be wrong)
2018-03-31T22:46:58 < dale6998> so, i start the clock, then stop the clock when i get back to the routine, and then use the CNT value to figure out how long it took
2018-03-31T22:46:59 < zyp> dale6998, yes, if the timer input clock is 84 MHz, and you don't prescale (divide by anything), each tick will be 1/84 MHz
2018-03-31T22:46:59 < Steffanx> the cypress stuff that is ofcourse.
2018-03-31T22:47:09 < dale6998> zyp: thank you
2018-03-31T22:47:22 < zyp> Steffanx, maybe, heard it's annoying to work with though
2018-03-31T22:47:53 < zyp> not sure how complex logic it'll let me put in the configurable fabric either
2018-03-31T22:48:01 < Steffanx> Perhaps, might have heard emeb complain about it yes.
2018-03-31T22:48:44 < zyp> N2HET would be great, but I don't need cortex-r and the price of hercules is also a turn-off :p
2018-03-31T22:49:26 < zyp> N2HET contains a whole processor with its own instruction interpreter, so it's super flexible
2018-03-31T22:50:13 < Steffanx> What do you want it to do? Just give it the number of pulses and the time it should generated those pulses in? And also handle the stuff when the you change any of those parameters?
2018-03-31T22:50:22 < Steffanx> -the
2018-03-31T22:51:06 < zyp> I wanna drive stepper drivers, i.e. give a pulse every time it should advance a step
2018-03-31T22:52:25 < zyp> each segment of the curve is described by length, speed and acceleration, so it would be great if I could just put a list of segments into memory and DMA it into something that can handle it with deterministic timing
2018-03-31T22:53:01 < Steffanx> And something like the SmartFusion stuff, cortex-m3 with fpga stuff would be too much?

2018-03-31T22:53:33 < Steffanx> Except that those SoC seems to be huge. package wise
2018-03-31T22:53:37 < Steffanx> *SoCs
2018-03-31T22:53:40 < zyp> I've looked at smartfusion before, IIRC it seems both expensive and hard to work with
2018-03-31T22:53:48 < emeb> Steffanx: me? complain?
2018-03-31T22:53:51 < zyp> so I never got as far as buying a devboard
2018-03-31T22:54:00 < Steffanx> oh not emeb?
2018-03-31T22:54:28 < zyp> one of those small lattice fpgas controlled by SPI might have been easier, but eh
2018-03-31T22:55:14 < zyp> probably way overkill
2018-03-31T22:55:21 < Steffanx> didnt you try/use that cypress PSoC stuff, emeb?
2018-03-31T22:55:31 < emeb> Steffanx: yeah - loooong ago.
2018-03-31T22:55:35 < Steffanx> but those lattice FPGAs are cheap though.
2018-03-31T22:55:37 < Steffanx> cheapish.
2018-03-31T22:55:51 < emeb> I might have noted that they're... not ideal for many things. :)
2018-03-31T22:56:16 < Steffanx> heh ok.
2018-03-31T22:56:24 < emeb> and yes - lattice FPGAs are cheap & cheerful. Easy to use, small.
2018-03-31T22:56:54 < zyp> right now I'm mostly wondering if for instance atmel would happen to have nice timers

2018-03-31T22:57:20 < zyp> englishman, which year?
2018-03-31T22:59:08 < zyp> I were originally considering replacing my old volvo 240 with a secondhand xc70
2018-03-31T22:59:14 < englishman> 2004
2018-03-31T22:59:45 < zyp> I think I were also looking at early two thousands
2018-03-31T23:00:06 < englishman> I should have bought an audi
2018-03-31T23:00:33 < englishman> much nicer to work on and parts are far cheaper
2018-03-31T23:00:56 < zyp> but then did 4000km behind the wheel in my friend's 2015 polo on a trip around norway, and realized I didn't want to spend money on a car without ACC
2018-03-31T23:01:13 < englishman> ACC?
2018-03-31T23:01:18 < zyp> adaptive CC
2018-03-31T23:01:22 < englishman> ah
2018-03-31T23:01:27 < englishman> yes it's great
2018-03-31T23:02:05 < zyp> at least half the time I'm driving I don't give a fuck about the speed, my car is just following the car in front of me
2018-03-31T23:03:21 < englishman> it was the only nice thing about tesla
2018-03-31T23:03:35 < englishman> I found pretty much everything else about the car to be awful
2018-03-31T23:03:50 < zyp> I've yet to drive a tesla, so I can't really comment

2018-03-31T23:10:28 < zyp> the egolf (new version with 50% longer range than mine) is well beaten on range now, but they were writing it's maybe still the most comfortable car to drive
2018-03-31T23:10:50 < zyp> I'm naturally biased since I own one, but I agree
2018-03-31T23:17:18 < zyp> hmm
2018-03-31T23:17:39 < zyp> the atmel sam series at a glance looks pretty shitty regarding timers

2018-03-31T23:18:25 < zyp> I'm reading that as six timer channels, and that's pretty shitty compared to the 20+ you'll have in a stm32

2018-03-31T23:31:59 < zyp> and the chip didn't seem to want to reset properly either, that might have been a BMP weakness at the time, but I tried messing around with that
