2018-11-01T00:19:23 < kakimir> I open task manager while youtube plays at background
2018-11-01T00:20:15 < kakimir> I move cursor from task manager to browser window and processor load increases 50percent units
2018-11-01T00:20:52 < kakimir> while the playback only requires like 30% when cursor is moved to browser window it can spike to 80%

2018-11-01T00:38:17 < englishman> apparently my pcb place will be offering padless vias soon
2018-11-01T00:46:04 < kakimir> padless vias
2018-11-01T00:47:14 < kakimir> interesting
2018-11-01T00:48:53 < englishman> indeed
2018-11-01T00:49:37 < kakimir> what are the implications?
2018-11-01T00:50:10 < kakimir> is there such cases where you _need_ padless vias
2018-11-01T00:50:35 < englishman> besides routing area, he said they crack less often after thermal cycles
2018-11-01T00:50:42 < englishman> because they can expand and contract
2018-11-01T00:50:50 < englishman> or something
2018-11-01T00:50:51 < zyp> what's a padless via?
2018-11-01T00:51:03 < kakimir> I assume annular ring = 0 zyp
2018-11-01T00:51:10 < englishman> http://www.cat-test.info/web_files/Understanding%20Process%20Capability,%20Quality%20and%20Reliability.pdf
2018-11-01T00:51:19 < zyp> that's what I thought too, but that sounds too easy
2018-11-01T00:51:35 < zyp> huh, cool
2018-11-01T00:52:34 < kakimir> thermal cycling huh
2018-11-01T00:52:42 < kakimir> I never thought vias would be an issue
2018-11-01T00:52:56 < kakimir> how hard cycling we are talking about?
2018-11-01T00:53:16 < englishman> idk he has a huge quantity of info on this stuff
2018-11-01T00:54:30 < kakimir> okay
2018-11-01T00:54:42 < kakimir> easier is to ask known applications for this tech
2018-11-01T00:54:48 < kakimir> actual products
2018-11-01T00:55:00 < englishman> he said motherboards
2018-11-01T00:55:02 < englishman> thats an easy one
2018-11-01T00:55:26 < kakimir> probs more about real estate than that thermal thing
2018-11-01T00:55:31 < englishman> yeah
2018-11-01T00:55:36 < kakimir> phones?
2018-11-01T01:01:29 < kakimir> 90% of projects I do I think - only if I needed no annular ring it would be so much easier

2018-11-01T01:48:55 < renn0xtk9> trying to flash a dummy programm on an stm32 board like this one, https://github.com/ubogdan/STM32F103C8T6
2018-11-01T01:49:03 < renn0xtk9> the led does not blink
2018-11-01T01:49:18 < renn0xtk9> the very same program worked on another board in the past
2018-11-01T01:49:26 < renn0xtk9> don;t know what is wrong with this new one
2018-11-01T01:51:02 < karlp> probably just shitty code.
2018-11-01T01:51:25 < karlp> do you have 128k flash? and 20k ram?
2018-11-01T01:51:46 < karlp> do you have a jlink?
2018-11-01T01:52:04 < renn0xtk9> karlp very new to stm32 so don't know what it is

2018-11-01T02:31:26 < renn0xtk9> Program received signal SIGTRAP, Trace/breakpoint trap.
2018-11-01T02:31:28 < renn0xtk9> WWDG_IRQHandler () at startup/startup_stm32.s:120
2018-11-01T02:31:35 < renn0xtk9> does not mean my programm does not even start?
2018-11-01T02:32:16 < jadew> no, it means that's where the code is located
2018-11-01T02:32:38 < jadew> are you not resetting the watch dog?
2018-11-01T02:36:55 < renn0xtk9> jadew I manually press on reset, I got a board like this https://pastebin.com/xAYr3T8w should not it reset the watchdog?
2018-11-01T02:37:15 < jadew> the watchdog has to be reset from your code
2018-11-01T02:37:39 < jadew> it's a feature that makes sure the firmware doesn't freeze
2018-11-01T02:37:55 < jadew> if it does, it resets the chip
2018-11-01T02:38:13 < jadew> and yeah, by the look of that code you're not doing this
2018-11-01T02:38:21 < jadew> so the watchdog gets triggered
2018-11-01T02:38:38 < jadew> which is why you're getting that thing in the debugger
2018-11-01T02:40:33 < renn0xtk9> okay, got some code snippet on how to do ?
2018-11-01T02:42:26 < jadew> google does
2018-11-01T02:50:43 < renn0xtk9> I am not clear about architecture of microcontroller
2018-11-01T02:50:57 < renn0xtk9> but I would have expecte the thing to crash but not to not even start?
2018-11-01T02:54:22 < renn0xtk9> jadew is it normal that it does not even enter the main?
2018-11-01T02:59:43 < renn0xtk9> jadew from here they say https://stackoverflow.com/questions/32532916/disabling-the-stm32-iwdg-during-debugging IWDG is disabled by default
2018-11-01T02:59:54 < renn0xtk9> I don't think it is the probelm honestly
2018-11-01T03:00:11 < renn0xtk9> that would not explain why that very same code worked with a very similar board

2018-11-01T03:57:21 < jadew> didn't know that, I only found it funny because I thought it explains why wolves/dogs are hauling at the moon

2018-11-01T10:48:05 < dongs> With Meadow, you don't have to spend your time fighting with hardware, you can focus on building innovative, professional, IoT solutions. And the best part is that you can leverage your existing C# and .NET skills to build solutions that are impractical on any other platform.
2018-11-01T10:54:44 < zyp> dongs, how do you like C# and .NET?
2018-11-01T11:01:48 < dongs> zyp, it was pretty usable back in 1.0 days
2018-11-01T11:01:55 < dongs> they added a bunch of new shit i have no idea how it works
2018-11-01T11:02:04 < dongs> autos, retarded shitty syntax etc
2018-11-01T11:02:18 < dongs> and it seems these days almost nobody actually writes .net code anymore
2018-11-01T11:02:26 < dongs> they just nigger toghether some "nuget" paockages
2018-11-01T11:02:35 < dongs> without having any clue of whats going on inside
2018-11-01T11:03:40 < zyp> isn't a lot of programming just a matter of putting together third party libs? :p

2018-11-01T11:43:17 < karlp> jadew: that wwdg irq handler was probably just an alias problem for the defualt blockinghandler.
2018-11-01T11:44:33 < zyp> yeah, that's common
2018-11-01T11:45:08 < zyp> when you have a bunch of symbols pointing to one address and do a reverse lookup, you tend to just get whatever matching symbol is found first
2018-11-01T11:45:30 < zyp> and since WWDG is the first IRQ, it was probably defined first
2018-11-01T11:46:31 < zyp> this is why you look at ISPR when you unexpectedly find yourself in a handler

2018-11-01T12:43:22 < renn0xtk9> I try to flash an stm32 on linux using stlink v2. I short BOOT0 and BOOT1 to 0, In my understanding it should write in main flash memory system 
2018-11-01T12:43:42 < renn0xtk9> however during the flash process I see this 2018-11-01T11:34:26 INFO flash_loader.c: Successfully loaded flash loader in sram
2018-11-01T12:43:57 < renn0xtk9> am I missunderstanding something?
2018-11-01T12:48:57 < karlp> you're looking for problems too much
2018-11-01T12:49:02 < karlp> that's just an info.
2018-11-01T12:49:34 < karlp> to make things work at sane speeds, most tools run some code in sram on the device to handle the flashing, so it's faster.

2018-11-01T12:51:36 < renn0xtk9> it so annoying, I had a code working, one year old, now I try to reflash that same code and it does not even start
2018-11-01T12:54:11 < karlp> do you have the old bin?
2018-11-01T12:54:29 < karlp> it's quite possible that the old code wwas borderling or relied on unintended other things that you don't have anymore
2018-11-01T12:54:43 < karlp> it's quite easy to make things appear to work in some limited manner that don't actually work.
2018-11-01T12:55:31 < karlp> what's your goal now, testing your flashing tools? testing your ocmpiler? I can suggest: https://github.com/libopencm3/libopencm3-miniblink
2018-11-01T12:55:59 < karlp> if you're looking for template starting point code, and you seemed to want to use stdperiph lib, I'd try starting with cubmex generated code, rather than some random blob on github
2018-11-01T12:57:50 < renn0xtk9> my goal is to make a toolchain that is working for compiling, flashing and debugging, in order to integrate it into the KDE "Kdevelop" editor, I thought I had a toolchain that was kinda working
2018-11-01T12:58:22 < renn0xtk9> but now it turns out no, and it is not clear to me if the flashing tool is broken, if the code is broken, if the startup code/ bootloader is broken

2018-11-01T13:09:16 < mawk> yes
2018-11-01T13:09:19 < renn0xtk9> the git thing is inside the make file 
2018-11-01T13:09:22 < mawk> ah
2018-11-01T13:09:25 < renn0xtk9> and that is why it fails

2018-11-01T13:09:30 < mawk> and modify it
2018-11-01T13:09:41 < mawk> the guy that did it didn't bother to test with an anonymous account
2018-11-01T13:09:52 < mawk> use fgrep -R to find where it is

2018-11-01T13:12:02 < renn0xtk9> karlp  or maybe just like my code, it kinda work
2018-11-01T13:12:22 < mawk> git:// url yes, but git@ which are ssh based
2018-11-01T13:12:25 < mawk> not on github at least
2018-11-01T13:12:34 < mawk> you can always hack something together to have anonymous ssh

2018-11-01T13:13:38 < mawk> the pubkey is site-wide
2018-11-01T13:14:06 < renn0xtk9> what is abstruse to me is the idea to put a git command in the makefile itslef :S
2018-11-01T13:14:22 < mawk> the makefile is doing something like git submodule update --init --recursive
2018-11-01T13:14:27 < mawk> the root repo needs other repos to work
2018-11-01T13:14:30 < mawk> it's pretty common
2018-11-01T13:14:50 < mawk> though I've seen it done it stuff like bootstrap scripts, not makefile; but it's not shocking
2018-11-01T13:15:11 < renn0xtk9> don t know, first time in my life i see this, Generally you put a configure.sh script on top of the toolchain. You dont want things getting updated when you make all 
2018-11-01T13:15:27 < renn0xtk9> it is very dangerours and unstable, if somebody break you external repo meanwhile
2018-11-01T13:15:32 < renn0xtk9> which is what happened
2018-11-01T13:15:33 < karlp> ok, git pull and rebuild

2018-11-01T15:52:05 < jadew> I have very high reservations regarding its performance :P
2018-11-01T15:52:34 < jadew> it might work, but not to 6 GHz
2018-11-01T15:53:11 < jadew> unless of course you simmulated the geometry and it looked fine
2018-11-01T15:53:27 < jadew> but otherwise, it looks like there are many impedance steps there
2018-11-01T15:53:53 < jadew> which will throw your return loss all over the place
2018-11-01T15:54:57 < jadew> at 6 GHz even a couple of mm of microstrip are meaningful

2018-11-01T16:01:53 < jadew> aandrew, my main concern are those wide pieces of copper
2018-11-01T16:02:02 < jadew> you said the thin ones are 50 ohm
2018-11-01T16:02:14 < jadew> if that's true, the other ones aren't, they'll be capacitive
2018-11-01T16:02:59 < jadew> and with such a small dielectric height, they might have enough capacitance to seriously screw with the impedance
2018-11-01T16:05:09 < jadew> same goes for the SMA connector

2018-11-01T16:07:38 < jadew> this is why higher dielectric height is prefered btw, it has better tollerance for manufacturing errors (track width, dielectric height) and it also allows you to mount stuff directly on it, without having to change its width to accomodate the pad

2018-11-01T16:13:43 < aandrew> jadew: it's entirely possible; his was done on osh's standard 4L which has a significantly thicker dielectric
2018-11-01T16:14:09 < aandrew> perhaps I should tell the board house to remove the copper on the inner layer where the resistors are
2018-11-01T16:14:19 < aandrew> either way, it'll be an interesting experiment

2018-11-01T16:36:53 < aandrew> that is very smart I think
2018-11-01T16:39:01 < aandrew> his original design just used an mcu and no fpga
2018-11-01T16:39:31 < aandrew> I might just take the gerbers and build it as-is though as a first pass so I have something to compare to
2018-11-01T16:40:14 < aandrew> a lot more reading to do before I tackle something like that though
2018-11-01T16:41:23 < karlp> were tehy really running into usb2-hs limits? or were they running into usb2-fs limits?
2018-11-01T16:41:51 < aandrew> don't know, I just think that for my own test equipment I'd prefer to have everything done over ethernet
2018-11-01T16:42:26 < aandrew> probably use SFP for isolation as well
2018-11-01T16:42:50 < aandrew> you could put the actual VNA and DUT into a faraday cage, run off a battery
2018-11-01T16:43:01 < aandrew> I actaully have a faraday cage with some microwave hardware around it
2018-11-01T16:43:04 < karlp> fun times having parasitic antennas from things like shutdown enable pins on ICSs
2018-11-01T16:43:10 < aandrew> bought it at an auction for a radar detector mfg
2018-11-01T16:43:22 < aandrew> thing is about 4' square and 2' tall
2018-11-01T16:43:29 < aandrew> not very big but interesting
2018-11-01T16:45:33 < aandrew> there is also a cheaper kickstarter one but only interested in that from a reference perspective: https://github.com/xaxaxa-dev/vna
2018-11-01T16:45:51 < aandrew> he's got an interesting directional coupler in there but no details on it
2018-11-01T16:46:12 < aandrew> If I'm going to build a VNA though it's going to be four port
2018-11-01T16:48:47 < aandrew> I'm really glad I didn't buy minivna/pocketvna
2018-11-01T16:49:02 < karlp> hrm, they've got the whole thing connected to an ft2232, so... 
2018-11-01T16:49:10 < aandrew> yes
2018-11-01T16:49:17 < aandrew> you don't need high speed for a VNA really
2018-11-01T16:49:20 < aandrew> it's not THAT much data
2018-11-01T16:49:37 < aandrew> but if you want to use it as SA a higher data rate helps your refresh/update rate
2018-11-01T16:49:52 < aandrew> in fact that's one thing I'm struggling to understand, why the sw for these isn't also supporting an SA mode
2018-11-01T16:50:33 < aandrew> don't know if I'm just being stupid, but it seems SA is a one-port, receive-only VNA where you're sweeping the LO and recording the measured power
2018-11-01T16:51:22 < karlp> one would think, yeah
2018-11-01T16:51:29 < karlp> should be just sw?

2018-11-01T19:25:25 < jadew> too busy with other stuff tho
2018-11-01T19:28:18 < jadew> I see his coupler looks similar to yours, so maybe it will work out
2018-11-01T19:28:35 < jadew> I suspect whoever designed it first took everything into account
2018-11-01T19:29:46 < aandrew> jadew: his coupler is where I got the idea from
2018-11-01T19:30:28 < aandrew> his process is the oshpark 4l stackup which has greater distance to the reference (which si wxactly what you cautioned I would probably need)
2018-11-01T19:30:51 < aandrew> there is no reason to have 3mil dielectric for the coupler, it's just what I have handy for this panel

2018-11-01T20:46:45 < jadew> would be great for enclosures
2018-11-01T20:47:07 < jadew> that thing + cheapest and decent CNC and you're set
2018-11-01T20:47:43 < jadew> you can make enclosures in large quantities at close to the plastic cost
2018-11-01T20:48:37 < jadew> considering the setup fee for injection molding is in the thousands, it might even be economical from the first run
2018-11-01T20:49:16 < jadew> ah... 2 cm3 injection volume
2018-11-01T20:49:25 < jadew> maybe a small enclosure
2018-11-01T20:50:36 < jadew> or maybe that doesn't matter? and it can push the plastic several times, until it fills the mold?
2018-11-01T20:50:57 < kakimir> it matters
2018-11-01T20:51:20 < jadew> so it has to be in one go otherwise it cools down differently, isn't it?

2018-11-01T21:38:51 < zyp> figure out what pins they are connected to, configure those pins
2018-11-01T21:39:04 < zyp> if you have embedded experience, I assume you know how to read a schematic?
2018-11-01T21:39:32 < ac_slater> zyp: yea just looking at what documentation is available
2018-11-01T21:39:36 < ac_slater> for the HAL
2018-11-01T21:39:38 < qyx> there is a manual for nucleo boards with schematics and pinouts
2018-11-01T21:39:44 < ac_slater> do I look at the nucleo or the stm, etc
2018-11-01T21:39:48 < ac_slater> thanks qyx 
2018-11-01T21:39:59 < zyp> the HAL doesn't have anything to do with the board layout
2018-11-01T21:40:05 < qyx> you can check what port to use (eg. PA5)
2018-11-01T21:40:07 < ac_slater> zyp: true

2018-11-01T21:42:12 < zyp> qyx, I don't disagree
2018-11-01T21:42:28 < qyx> is it a plasterboard on the ceiling?

2018-11-01T21:44:28 < qyx> like it is usually done on a gipsum plasterboard?
2018-11-01T21:45:46 < zyp> that's the advantage of prepainted stuff

2018-11-01T21:52:12 < sync> interesting
2018-11-01T21:52:30 < zyp> also upstairs bathroom floor will have a thin layer of concrete
2018-11-01T21:52:41 < ac_slater> ie - I'm sure there are constants for a lot of the mappings, but damned if I know where those are

2018-11-01T21:53:08 < sync> that is how they usually do it here
2018-11-01T21:53:13 < zyp> ac_slater, I don't use HAL myself, but my impression is that there's no board layer
2018-11-01T21:53:35 < ac_slater> zyp: makes sense I gues
2018-11-01T21:54:01 < ac_slater> so then the GPIO constants/pins must be in the chip layer
2018-11-01T21:54:03 < ac_slater> thanks guys
2018-11-01T21:54:10 < zyp> apart from the demo boards like discovery/nucleo, most boards are project specific so you'd have to make your own anyway
2018-11-01T21:54:31 < qyx> sync: here (sk) too, but many modern houses are superinsulated now and use some alternative approaches
2018-11-01T21:55:04 < sync> yeah but the insulation goes on the outside
2018-11-01T21:55:10 < sync> doesn't change a lot on the inside
2018-11-01T21:55:12 < qyx> sync: like this http://www.git.sk/public/images/referencia/vystavba-RD-drevodom-Ratnovce-1.jpg
2018-11-01T21:55:14 < sync> maybe the ventilation
2018-11-01T21:55:17 < ac_slater> zyp: right
2018-11-01T21:55:18 < qyx> concrete is only on the bottom
2018-11-01T21:55:28 < sync> ewwww
2018-11-01T21:55:42 < zyp> qyx, that looks more like here
2018-11-01T21:55:55 < zyp> but the OSB wall panels or whatever that is looks strange
2018-11-01T21:56:04 < qyx> yes, osb
2018-11-01T21:56:35 < zyp> do they use that as a wind breaking layer?
2018-11-01T21:56:36 < qyx> but regular houses still use some sort of ytong/premac or ceramic bricks
2018-11-01T21:56:44 < sync> yeah, that style of construction is getting more popular here but eh
2018-11-01T21:56:50 < sync> they are cheap, that is about it
2018-11-01T21:56:51 < qyx> the osb also has static function
2018-11-01T21:57:19 < ac_slater> zyp: but I still have to know which pin 'PB7' goes to
2018-11-01T21:57:25 < ac_slater> for example
2018-11-01T21:57:36 < zyp> PB7 is a pin
2018-11-01T21:57:37 < qyx> porfix, not premac
2018-11-01T21:58:00 < zyp> ac_slater, or rather, PB7 is a pin function, it's the seventh bit of GPIOB
2018-11-01T21:58:13 < ac_slater> nice, that makes sense
2018-11-01T21:58:19 < ac_slater> I should read the documentation and leave you guys alone
2018-11-01T21:58:26 < ac_slater> I literally just opened this thing 20 minutes ago
2018-11-01T21:58:28 < ac_slater> thanks?!
2018-11-01T21:58:30 < ac_slater> thanks! *
2018-11-01T21:58:46 < qyx> gl, there are thousands of pages of reference manuals
2018-11-01T21:58:58 < qyx> just pick some example and try to understand
2018-11-01T21:59:16 < zyp> my house just have this isola sheet thing as a wind breaking layer behind the outdoor paneling: https://bin.jvnv.net/file/VKBSI.jpg
2018-11-01T22:00:06 < ac_slater> qyx: thats the problem actually, no real examples in stm32cube, and the internet is full of cubemx or arduino stuff since the nucleo has some relation to arduino
2018-11-01T22:00:12 < zyp> outdoor paneling, couple centimeter gap for ventilation, wind breaking layer, 15cm of insulation, moisture blocking layer, another 5cm of insulation, inside MDF panel
2018-11-01T22:00:31 < qyx> similar to what I have
2018-11-01T22:00:58 < zyp> https://bin.jvnv.net/file/IX88h.jpg <- here's how it looks on the inside
2018-11-01T22:01:30 < qyx> plasterboard, metal grid, vapour block membrane, 15cm of insulation in the wooden construction, osb, 8cm insulation, 8cm insulation, wind stop, gap, facade panel
2018-11-01T22:02:08 < qyx> yeah, very similar construction
2018-11-01T22:02:10 < zyp> passive house level insulation?
2018-11-01T22:02:29 < qyx> near passive, I do not have any obligation to make it passive

2018-11-01T22:02:35 < zyp> 31cm sounds like quite a lot
2018-11-01T22:05:07 < sync> I wonder when they realize that passive level is not the best thing to do
2018-11-01T22:06:52 < zyp> why not?
2018-11-01T22:08:13 < sync> because you have to be quite careful to keep the dewpoint in the wall outside the inner layer
2018-11-01T22:08:31 < zyp> yeah?
2018-11-01T22:08:45 < qyx> yes, otherwise the water condenses and cannot escape
2018-11-01T22:08:52 < qyx> in the insulation
2018-11-01T22:08:52 < zyp> that's why the vapour block is supposed to go on the inside of most of the insulation
2018-11-01T22:08:57 < sync> there are tons of passive/positive energy houses here in germany that need massive renovation only 10-15 years after they were built
2018-11-01T22:09:22 < sync> the vapor block does not help at all, as you still have moisture from the inside
2018-11-01T22:09:36 < sync> and it also depends on how the house is ventilated
2018-11-01T22:09:48 < sync> and how the people heat/vent
2018-11-01T22:09:54 < zyp> the entire point of the vapor block is to keep the inside moisture inside
2018-11-01T22:10:19 < sync> yes, but not as a liquid
2018-11-01T22:10:37 < qyx> it wont be as a liquid of the vapour block is on the right place
2018-11-01T22:10:42 < qyx> *if
2018-11-01T22:11:50 < sync> as I said, that is hard to control depending on how the people live in there

2018-11-01T22:12:23 < zyp> I think the rule of thumb here is that at least 70% of the insulation goes outside the vapor block
2018-11-01T22:12:42 < zyp> also, balanced ventilation is also pretty much a requirement here now
2018-11-01T22:15:51 < zyp> https://bin.jvnv.net/file/JrvJJ.jpg <- stuff like this
2018-11-01T22:17:13 < kakimir> do you plan to feature heat pump unit to ventilation?
2018-11-01T22:17:34 < zyp> no, I'm planning to just get a plain air/air heat pump
2018-11-01T22:17:59 < qyx> a dedicated unit?
2018-11-01T22:18:01 < sync> yeah, the effiency gain is not too great
2018-11-01T22:19:23 < zyp> the ventilation system supports being hooked up to a liquid heating/cooling system, but I don't have that
2018-11-01T22:20:22 < zyp> bit shame, if I had a larger budget and were thinking about it earlier, I would have wanted liquid heating in all floors
2018-11-01T22:21:24 < zyp> ground/water heat pump seems neat
2018-11-01T22:21:35 < zyp> expensive upfront, but good efficiency
2018-11-01T22:21:35 < qyx> and doing heating using the ventilation is not a feasible solution?
2018-11-01T22:21:39 < qyx> I am going to do it that way

2018-11-01T22:22:33 < zyp> yes
2018-11-01T22:23:12 < qyx> I meant using an air-water heatpump and connect it to the ventilation unit
2018-11-01T22:23:13 < ac_slater> just real quick guys. In STM32CUBE-F7, there is in fact a NUCLEO BSP layer as well as the normal STM32 HAL stuff
2018-11-01T22:23:15 < ac_slater> just to put that to rest
2018-11-01T22:23:16 < zyp> there's a heat exchanger that preheats it from the outgoing air, and then the electric heater brings it up to temperature so you don't get a bunch of cold air from the inlets
2018-11-01T22:23:42 < zyp> ac_slater, good to know, then I'll stop misinforming in the future :)

2018-11-01T22:24:13 < ac_slater> thanks for the help all
2018-11-01T22:24:52 < johntramp> I am getting a lot of UART noise on my 3v3 rail when I have a cable attached to the RX/TX pins, when not connected it is significantly better. This noise is affecting the sensor readings, and I need the UART cable for datalogging the sensor data for development. I am guessing I should be trying to shield the UART cable somehow ... what would be the best way to do this?
2018-11-01T22:25:20 < zyp> sounds like you need better decoupling/filtering
2018-11-01T22:25:32 < zyp> or maybe try reducing the drive strength on the UART pins
2018-11-01T22:25:44 < johntramp> ah nice idea
2018-11-01T22:26:19 < johntramp> I am running the UART quite fast, about 2MHz or so, which i'm sure won't be helping ...
2018-11-01T22:28:56 < Thorn> maybe you need termination on your uart lines (but @ 2 MHz reducing drive strength ought to be a better idea)
2018-11-01T22:30:12 < jpa-> yeah, what others already said: more ceramic caps on 3.3V rail, and lower drive strength in gpio config
2018-11-01T22:32:38 < Thorn> also are you sure it's not due to bad probing (and your sensor problems are unrelated)?
2018-11-01T22:33:15 < Rickta59> are you using a 3v3 uart?
2018-11-01T22:34:50 < johntramp> Thorn: I am getting corrupt ADC readings outs the IMU which has lead me to where I am now
2018-11-01T22:35:37 < Thorn> maybe there is a ground loop when the cable is attached
2018-11-01T22:35:42 < Steffanx> Yes, i do, but do you know crt ?
2018-11-01T22:35:51 < johntramp> https://i.imgur.com/FEzdapj.jpg  here is what I am seeing on 3v3, it is pretty horiffic ..
2018-11-01T22:36:16 < Steffanx> Was he ever?
2018-11-01T22:36:40 < ac_slater> zyp: qyx, I got it working via using the `stm32f7xx_nucleo_144.{c,h}` BSP. Super cool. Thanks guys!
2018-11-01T22:36:50 < qyx> \o/
2018-11-01T22:36:50 < ac_slater> those are all from STM32CUBE
2018-11-01T22:37:12 < ac_slater> the STM32CUBE documentation is actually really good and describes the layers.
2018-11-01T22:37:30 < jpa-> johntramp: how much caps do you have on 3.3V?
2018-11-01T22:37:59 < jpa-> (and how close to mcu)
2018-11-01T22:38:24 < Thorn> johntramp: if you're seeing short pulses when there're transitions in uart signals (i.e. d(signal)/dt) it could be magnetic field picked up by the probe ground connection
2018-11-01T22:39:00 < jpa-> also there seems to be quite a lot of ripple even without the uart, is your smps doing PFM or something?
2018-11-01T22:39:26 < johntramp> here is the output data from the IMU at different scales https://i.imgur.com/I8w8Aud.png https://i.imgur.com/Ak1MUVu.png https://i.imgur.com/nAdD9S0.png
2018-11-01T22:39:49 < johntramp> jpa-:  yes i think it is different smps modes
2018-11-01T22:39:54 < Thorn> does it change when you change uart speed?
2018-11-01T22:40:42 < jpa-> johntramp: if this isn't very power-sensitive, i suggest to disable PFM mode and only use PWM mode, because when load is small PFM can cause a lot of low-frequency noise
2018-11-01T22:40:46 < johntramp> jpa-: i have 200nF on the MCU, 200nF on the IMU, 10uF and 100uF on the SMPS output
2018-11-01T22:41:14 < jpa-> sounds like a reasonable amount
2018-11-01T22:42:17 < zyp> remember that for decoupling it's not the total amount of capacitance that matters, it's where it's located
2018-11-01T22:42:59 < zyp> phrasing it as "200nF on the MCU" doesn't sound very reassuring
2018-11-01T22:43:10 < johntramp> Thorn: the clock speeds don't seem to make much difference
2018-11-01T22:43:31 < qyx> can you show the layout?
2018-11-01T22:45:46 < johntramp> yeah one sec, i am pretty sure it is okay

2018-11-01T22:50:29 < qyx> wheres the 100uF?
2018-11-01T22:50:40 < jpa-> does it have adjustable gpio drive strength? if not, putting series resistors on the pins would be a good idea
2018-11-01T22:51:08 < johntramp> qyx: that is bodged onto another board which I am actually using
2018-11-01T22:51:39 < johntramp> jpa-: yes it is either 1ma or 10ma, I am not sure what the default setting is though as i hadn't set it either way
2018-11-01T22:52:01 < johntramp> I am just trying setting all to 1ma now  ....
2018-11-01T22:52:57 < jpa-> somehow the ripple seems too high though; even with a several meters long cable, you'd have at most 1nF capacitance, which should give less than 20mV of ripple
2018-11-01T22:53:57 < qyx> are the tx/rx traces going underneath?
2018-11-01T22:53:58 < johntramp> yes the ~200mv pk-pk out the smps seems high to me but this is the first time i have used one
2018-11-01T22:54:20 < qyx> you need big traces on the smps
2018-11-01T22:54:29 < qyx> lx pins, L to cap
2018-11-01T22:54:32 < qyx> input cap to Vin
2018-11-01T22:54:33 < qyx> etc.
2018-11-01T22:54:59 < qyx> short distances, consider voltage derating of the caps
2018-11-01T22:54:59 < jpa-> it could be that the smps inductor is sized wrong or the smps controller is not good enough for the kind of load you have, and becomes unstable
2018-11-01T22:55:29 < Thorn> or not compensated properly
2018-11-01T22:55:33 < qyx> is it a buck converter?
2018-11-01T22:55:41 < johntramp> boost
2018-11-01T22:55:45 < qyx> why is the input connected to the L directly?
2018-11-01T22:55:48 < qyx> ah, makes sens then
2018-11-01T22:57:43 < johntramp> the datasheet for the smps shows ~30mv ripple when in pfm mode, but I am seeing closer to 200mv ...
2018-11-01T23:01:15 < qyx> does the mems have analol outputs?
2018-11-01T23:02:33 < johntramp> no just spi/iic
2018-11-01T23:04:09 < qyx> wait what
2018-11-01T23:04:35 < qyx> is there a noise on your readings when using a spi mems?
2018-11-01T23:04:59 < johntramp> yes
2018-11-01T23:05:27 < qyx> how does the noise look? is it caused by bit-flips? or is it "analog"?
2018-11-01T23:05:34 < johntramp> so i figured the noise was on the 3v3 rail to the adc
2018-11-01T23:05:52 < johntramp>  https://i.imgur.com/I8w8Aud.png https://i.imgur.com/Ak1MUVu.png https://i.imgur.com/nAdD9S0.png    
2018-11-01T23:06:35 < qyx> so the noise ~correlates to the vdd noise
2018-11-01T23:06:41 < johntramp> yes
2018-11-01T23:07:07 < johntramp> so i figured it was adc noise from the vdd
2018-11-01T23:07:33 < qyx> I would try to increase the smps output capacitance
2018-11-01T23:07:53 < johntramp> output capacitance??
2018-11-01T23:07:53 < qyx> also you could break the 0R bridge and do a simple 1order filter
2018-11-01T23:08:07 < qyx> just for the lulz
2018-11-01T23:08:38 < qyx> and what others say
2018-11-01T23:08:58 < qyx> minimize the noise or filter it out
2018-11-01T23:09:20 < johntramp> yeah I would like to clean it up as much as possible before having to do software filters
2018-11-01T23:09:46 < johntramp> do you think it is worth trying to add more bulk capacitance to the imu vdd?
2018-11-01T23:09:51 < qyx> you said there is a 10uF cap, from the picture it looks like 0805
2018-11-01T23:10:25 < qyx> I would piggyback another one on top of it
2018-11-01T23:10:44 < johntramp> yes that's right
2018-11-01T23:11:01 < johntramp> yea ok i'll try that
2018-11-01T23:11:22 < qyx> idk if it helps, it may make things worse
2018-11-01T23:14:20 < johntramp> setting all the drive strengths to 1ma seemed to make no difference
2018-11-01T23:14:26 < johntramp> perhaps that was the default ...
2018-11-01T23:17:49 < johntramp> ah ok it is a tiny bit better with the drive strength at 1ma

2018-11-02T00:03:35 < Ultrasauce> idk but that definitely does sound like something that would happen here
2018-11-02T00:03:41 < Thorn> https://www.youtube.com/watch?v=5boa6wAK0Sc
2018-11-02T00:04:33 < englishman> cool
2018-11-02T00:05:23 < qyx> I didn't buy it, it was someone else
2018-11-02T00:17:20 < jadew> englishman, that's because I don't need one at the moment, but you do realize you're talking about technology that a tarduino user can put together in under an hour, right?
2018-11-02T00:18:06 < jadew> there's nothing special about a temperature logger, zero difficult parts
2018-11-02T00:20:08 < jadew> it's lower frequency even than audio shit, it's been done 1 billion times before, with all possible types of sensors and requires less than dial-up data rates
2018-11-02T00:20:13 < Steffanx> under an hour my arse.
2018-11-02T00:20:17 < jadew> even if you try, you can't get it wrong
2018-11-02T00:20:18 < Steffanx> + desktop tool
2018-11-02T00:20:28 < jadew> that's why I said 1 week
2018-11-02T00:20:32 < jadew> desktop tool + case
2018-11-02T00:22:50 < Steffanx> its only 350e.. what is that, 5 hours of work?
2018-11-02T00:23:16 < jadew> my point was that it's overpriced for something that takes so little to design
2018-11-02T00:23:31 < jadew> and build, if you're considering a DIY thing
2018-11-02T00:23:45 < jadew> as a DIY you don't even have to worry about a fancy program and an enclosure
2018-11-02T00:23:49 < jadew> you can have wires hanging
2018-11-02T00:24:04 < englishman> yeah I know how thermocouples work dude
2018-11-02T00:24:38 < englishman> it is absolutely an Arduino mentality to clone a $200 product that a company has been making since 1995 because #metoo
2018-11-02T00:24:45 < englishman> and still, noone has
2018-11-02T00:25:07 < Steffanx> $400
2018-11-02T00:25:14 < Steffanx> ebay discount does not count :P
2018-11-02T00:25:14 < englishman> close enough
2018-11-02T00:25:25 < englishman> I got my $400 out of it that's for sure
2018-11-02T00:25:55 < jadew> just because you can earn 1 million with a spanner, doesn't mean you have to pay 500k for it
2018-11-02T00:26:16 < qyx> I just spent an hour searching for a temperature sensor
2018-11-02T00:26:20 < qyx> not that easy
2018-11-02T00:26:23 < jadew> heh
2018-11-02T00:27:10 < Steffanx> great comparison jadew :P
2018-11-02T00:29:00 < jadew> thing is, I'd love to know how to sell products like that
2018-11-02T00:29:20 < qyx> they have to be cool enough
2018-11-02T00:29:50 < jadew> qyx, the product?
2018-11-02T00:30:01 < qyx> the spanner is, picologger too
2018-11-02T00:30:20 < jadew> I think you're right
2018-11-02T00:30:38 < jadew> but englishman bought it from other considerents
2018-11-02T00:30:52 < qyx> desktop based logger isn't for example
2018-11-02T00:31:05 < jadew> somehow they figured out what the gap is between people who wouldn't buy one and those who would
2018-11-02T00:31:11 < qyx> it is just a boring box with some wires and usb
2018-11-02T00:31:23 < jadew> and priced it specifically for those who would
2018-11-02T00:31:49 < jadew> qyx, well, that's what the picologger is
2018-11-02T00:33:15 < jadew> I'm willing to bet you $1000 that if you ask everyone in this channel to log temperature over several hours, 90% of them will find a cheaper or free way of doing it
2018-11-02T00:33:34 < jadew> be it either with a meter or some hacky solution with $5 parts from ebay
2018-11-02T00:34:00 < jadew> but the pico guys figured that there are customers that would rather not to do that
2018-11-02T00:34:11 < jadew> and also figured what those customers would pay for it
2018-11-02T00:34:13 < jadew> that's skill
2018-11-02T00:38:26 < aandrew> no it's not a good comparison at all
2018-11-02T00:38:35 < aandrew> yes you can rig up a simple temp logger in a few horus
2018-11-02T00:38:52 < aandrew> but there's a reason people will pay a couple hundred for something ready made that just does what you want with zero dicking around
2018-11-02T00:39:29 < jadew> clearly, doesn't mean the device is worth that much tho
2018-11-02T00:39:42 < aandrew> see you're making the classing engineering mistake
2018-11-02T00:39:44 < aandrew> classic
2018-11-02T00:39:53 < aandrew> what does "worth" mean? it is *not* the BOM cost
2018-11-02T00:39:58 < aandrew> it's how much someone is willing to pay
2018-11-02T00:39:59 < jadew> that's true
2018-11-02T00:40:11 < aandrew> this was a lesson that took me a damn long time to learn
2018-11-02T00:40:13 < aandrew> embarassingly long
2018-11-02T00:40:24 < aandrew> it took me running with the sales team when I worked for someone else 
2018-11-02T00:40:36 < aandrew> you don't charge what it costs
2018-11-02T00:40:40 < aandrew> you charge what someone is willing to pay
2018-11-02T00:41:02 < jadew> yeah, I kinda wonder how you figure that out tho
2018-11-02T00:41:03 < aandrew> also if there's ANY support involved your MINIMUM cost should be something like 4x BOM
2018-11-02T00:41:06 < aandrew> at absolute minimum
2018-11-02T00:41:08 < jadew> changing price from sale to sale?
2018-11-02T00:41:11 < aandrew> jadew: you do market research
2018-11-02T00:41:16 < aandrew> and start out with $x

2018-11-02T01:04:27 < catphish> now today i've had 5 different people, all from 100+ miles away, all immigrants with terrible english skills, all wanting to buy it

2018-11-02T01:36:50 < jadew> it's possible your listind wasn't even shown to others until now
2018-11-02T01:38:12 < catphish> i did change the location last week, previously it was incorrect, and listed in some weird part of africa, so maybe that change just rolled out
2018-11-02T01:38:48 < catphish> i guess that would explain why noody saw it until recently, i'd forgotten about that because it was a week ago
2018-11-02T01:38:56 < jadew> hah
2018-11-02T01:39:13 < catphish> now suddenly today it's in everyone's facebook feeds i guess due to some weird algorithm magic
2018-11-02T01:39:29 < jadew> so it was listed somewhere where people didn't even have electricity
2018-11-02T01:39:38 < jadew> no wonder it didn't sell

2018-11-02T01:43:05 < jadew> I live in Romania
2018-11-02T01:43:24 < catphish> oh, i think you told me that before actually :)
2018-11-02T01:43:25 < jadew> was thinking that maybe I can drive over to buy the speakers

2018-11-02T01:43:41 < catphish> sure you can
2018-11-02T01:43:49 < catphish> while we're still in the EU
2018-11-02T01:43:56 < jadew> hah, right
2018-11-02T01:43:59 < jadew> forgot about that
2018-11-02T01:44:11 < jadew> maybe I should wait a bit and buy them at half the price :P
2018-11-02T01:44:42 < catphish> if you come collect them, you can have them for free :)

2018-11-02T01:46:55 < catphish> oops
2018-11-02T01:47:04 < jadew> I'm sure you'll do just fine
2018-11-02T01:47:24 < catphish> i hope so
2018-11-02T01:47:42 < catphish> won't make much difference to me, except it might screw up my chinese imports :(
2018-11-02T01:47:49 < jadew> the biggest challenge won't be the work force, you can always import more if you need it
2018-11-02T01:47:56 < jadew> it's going to be the trade deals
2018-11-02T01:48:33 < catphish> i'm hoping mostly trade deals with countries outside the eu wont change much
2018-11-02T01:48:40 < catphish> but i guess we have less bargaining power now
2018-11-02T01:48:47 < jadew> yeah
2018-11-02T01:49:14 < jadew> what are you guys producing?
2018-11-02T01:49:18 < catphish> but im sure china will still be happy to send up cheap shit :)
2018-11-02T01:49:35 < jadew> for sure
2018-11-02T01:49:40 < catphish> afaik we mostly produce services, we have smart engineers
2018-11-02T01:49:48 < jadew> unless you team up with the US against china's cheap stuff
2018-11-02T01:49:52 < catphish> and complicated finance stuff
2018-11-02T01:50:08 < jadew> interesting you say that, I have a friend who works in finance in the UK
2018-11-02T01:50:15 < jadew> (programmer)
2018-11-02T01:50:18 < jadew> we grew up together
2018-11-02T01:50:29 < catphish> cool
2018-11-02T01:50:31 < jadew> actually not sure if he's doing that anymore
2018-11-02T01:50:45 < catphish> sounds pretty boring
2018-11-02T01:50:49 < catphish> but lots of money in it
2018-11-02T01:50:58 < jadew> he did a lot of job hopping
2018-11-02T01:51:06 < jadew> yeah
2018-11-02T01:51:55 < jadew> what I was hinting at is that if you kick these people out, you might not have what services to sell :P
2018-11-02T01:52:15 < catphish> yea, they'll realise that soon
2018-11-02T01:52:34 < jadew> on the other hand, for the capable people there, things will get better
2018-11-02T01:55:28 < jadew> I understand why people voted for brexit in the idea of stopping immigration
2018-11-02T01:55:52 < catphish> i'm not sure i do
2018-11-02T01:56:07 < catphish> i mean, i don't think there's any one reason
2018-11-02T01:56:16 < aandrew> brexit is a fucking joke
2018-11-02T01:56:18 < catphish> i have some idea, but there are lots of reasons
2018-11-02T01:56:26 < jadew> well, those who voted for that because of immigration did it because they saw the immigrants as a displacement force
2018-11-02T01:56:39 < jadew> they were taking their jobs
2018-11-02T01:56:44 < jadew> and that's true to an extent
2018-11-02T01:56:50 < jadew> but globalisation goes beyond that
2018-11-02T01:57:08 < jadew> immigrants were mostly taking the bottom jobs (which are jobs too, but of least importance)
2018-11-02T01:57:11 < catphish> actually i don't think that's the main reason
2018-11-02T01:57:21 < jadew> the important ones are unfortunately being exported over the internet
2018-11-02T01:57:25 < jadew> and there's no stopping that
2018-11-02T01:57:33 < catphish> i've not spoken to anyone who was worried about their own employment, we have very low unemployment here
2018-11-02T01:57:51 < jadew> catphish, what were their reasons then?
2018-11-02T01:57:57 < catphish> you could assume that but i think you'd be wrong
2018-11-02T01:58:15 < catphish> the concern was about "resources" in general
2018-11-02T01:58:38 < catphish> for example the capacity of the health service, capacity of the schools, housing
2018-11-02T01:59:00 < catphish> basically the feeling is that the country is "full"
2018-11-02T01:59:15 < jadew> I see
2018-11-02T01:59:31 < catphish> jobs is one part of it, but most people talk about medical and education being too stretched
2018-11-02T01:59:42 < catphish> and not being able to scale to any more people
2018-11-02T02:00:28 < jadew> they're free?
2018-11-02T02:00:36 < jadew> "free"
2018-11-02T02:00:36 < catphish> yes, all free here
2018-11-02T02:00:42 < jadew> I see
2018-11-02T02:01:07 < jadew> well, if the immigrants were pulling their weight, I don't see how that could have been a problem
2018-11-02T02:01:29 < catphish> of course people say that immigrants work and pay tax and pay for those things, and they work as doctors and teachers
2018-11-02T02:01:55 < jadew> but?
2018-11-02T02:02:05 < catphish> but xenophobes are just not convinced, they think we have finite resources and they will not stretch
2018-11-02T02:03:38 < jadew> hard to debate that without having the data
2018-11-02T02:03:48 < catphish> correct, but people do anyway :)
2018-11-02T02:04:20 < catphish> because it's esier to appeal to emotions than make people look at facts
2018-11-02T02:05:16 < catphish> personally agree that we have scaling problems with our infrastructure, i do not want our population to rise, but i direct more anger towards people having babies than immigrants who already exist
2018-11-02T02:05:42 < jadew> I think you're wrong there
2018-11-02T02:05:48 < jadew> I mean... if that is really a problem
2018-11-02T02:06:09 < jadew> I think the people there have more right to have more babies than the immigrants have to go there
2018-11-02T02:06:38 < jadew> if someone has to refrain from having babies so that someone who has no investment in your country can get to live there, then no
2018-11-02T02:06:40 < jadew> that's not right
2018-11-02T02:07:27 < catphish> but babies have no investment in the country, they are created from nothing
2018-11-02T02:07:36 < catphish> and they purely consume
2018-11-02T02:07:46 < jadew> they are created by the people who have invested in that country
2018-11-02T02:07:51 < jadew> their ancestors have died for them
2018-11-02T02:07:59 < catphish> i wish that were always true :)
2018-11-02T02:09:08 < catphish> the argument is that if world population was under control, migration would not be a problem
2018-11-02T02:09:28 < catphish> people would simply distribute uniformly according to available resources
2018-11-02T02:09:58 < catphish> but world population is much too high, so we have to fight
2018-11-02T02:10:19 < jadew> well, thing is "resources" in this day are created, not exploited
2018-11-02T02:10:27 < jadew> like you said, services
2018-11-02T02:10:53 < catphish> that's true to a limited extent
2018-11-02T02:11:08 < catphish> but humand need things that can't be created
2018-11-02T02:11:15 < jadew> like what?
2018-11-02T02:11:30 < catphish> living space being the most critical
2018-11-02T02:11:41 < jadew> there's lots of space in africa
2018-11-02T02:11:42 < catphish> and living space adjacent to drinkable water
2018-11-02T02:12:03 < jadew> again, that's something that can be built
2018-11-02T02:12:08 < jadew> there's such a thing as pipes
2018-11-02T02:12:08 < catphish> i would not be very happy being located to a desert
2018-11-02T02:12:30 < catphish> and so we fight over the best places
2018-11-02T02:12:45 < jadew> we already did tho
2018-11-02T02:12:58 < catphish> and why do i have more right to live here then someone who was born in africa?
2018-11-02T02:13:15 < jadew> because your ancestors risked their lives to get there
2018-11-02T02:13:19 < aandrew> catphish: isn't 25% of the british population employed by government?
2018-11-02T02:13:19 < catphish> that's the main problem of all, how do you define who has the right to live where?
2018-11-02T02:13:23 < jadew> many died
2018-11-02T02:13:44 < jadew> then a lot more many died in order to protect that place, for their children, for you
2018-11-02T02:13:55 < catphish> jadew: now that's where it gets cool, what about the people who risk their lives now to migrate?
2018-11-02T02:14:09 < aandrew> most who voted to leave voted out of fear from unsubstantiated news and rumour
2018-11-02T02:14:17 < aandrew> lots of scare mongering about losing jobs and shit
2018-11-02T02:14:34 < catphish> aandrew: if you include everything funded by taxation as the government, probably yes
2018-11-02T02:14:54 < aandrew> catphish: was just a rumour I had heard years ago, wasn't sure how real it was
2018-11-02T02:15:02 < jadew> catphish, well, the people migrating now are migrating towards a place they know it's cozy, because it was made cozy by others
2018-11-02T02:15:12 < jadew> they're not taking the same risks
2018-11-02T02:15:17 < jadew> also, that land is occupied
2018-11-02T02:15:27 < jadew> and the occupants get to say who comes in and who doesn't
2018-11-02T02:15:29 < catphish> aandrew: we have very high taxes that cover a lot of services that are then provided free
2018-11-02T02:15:39 < jadew> or they can take it by force (that's always an option)

2018-11-02T02:16:19 < catphish> jadew: england for example was not "made cozy" it's always had exceptionally good climate and availability of resources
2018-11-02T02:16:35 < jadew> catphish, but was it safe?
2018-11-02T02:16:41 < jadew> I think not
2018-11-02T02:17:36 < catphish> jadew: not sure why this is relevent though, who's to say who they wanted living there, and what right they have to make that decision either :)
2018-11-02T02:17:56 < jadew> well, they didn't have the right, they took it
2018-11-02T02:18:04 < jadew> they died for it, I think that's a pretty high price
2018-11-02T02:18:10 < catphish> jadew: i mean, people in the USA died to protect slavery, that doesn't make it right
2018-11-02T02:18:47 < jadew> still, if they would have won, what could you have done to change their mind?
2018-11-02T02:19:08 < jadew> it would have required a similarly high sacrifice
2018-11-02T02:19:11 < jadew> a fight
2018-11-02T02:19:18 < catphish> aandrew: i'm pretty happy with it, means i know i likely never have to worry about being looked after
2018-11-02T02:19:48 < catphish> plus in case it's not obvious i'm an insufferable leftie who just wants everyone to be catered for

2018-11-02T02:20:21 < jadew> that's fine, it's a good sentiment, but I don't think it's sustainable
2018-11-02T02:21:03 < catphish> well the more world population grows, the less sustainable it becomes
2018-11-02T02:21:05 < jadew> for example, if the entire country got flooded by low skilled workers or people who just wanted to take advantage of your care-free system - what would happen to the system you rely on?
2018-11-02T02:21:57 < catphish> ideally we develop a global population with enough wealth to look after everyone

2018-11-02T02:22:14 < catphish> as we just about have here
2018-11-02T02:22:26 < jadew> won't happen
2018-11-02T02:22:52 < catphish> not unless we can get our birth rates in the less developed countries under control
2018-11-02T02:23:07 < jadew> try to tell them that...
2018-11-02T02:23:18 < catphish> if the UK were to stop all migration we'd be ok, we have a naturally shrinking population
2018-11-02T02:23:32 < catphish> because the birth rate no longer exceeds the death rate
2018-11-02T02:23:36 < jadew> thing is, when times are hard people multiply
2018-11-02T02:23:50 < catphish> that's astonishingly dumb
2018-11-02T02:23:59 < jadew> so stopping population growth in less developed countries is going to be impossible
2018-11-02T02:24:01 < catphish> but probably instinctual
2018-11-02T02:24:03 < jadew> it's just human nature
2018-11-02T02:24:04 < jadew> yeah
2018-11-02T02:24:23 < catphish> i will never have children, just don't have the urge to
2018-11-02T02:25:07 < catphish> so i guess that's like 2 more immigrants the UK can handle instead :)
2018-11-02T02:25:12 < jadew> that's also fine... but just so you know, they're awesome
2018-11-02T02:25:21 < catphish> i hate them
2018-11-02T02:25:29 < jadew> you may hate other people's kids
2018-11-02T02:25:44 < jadew> but if they were yours it would be a completely different story
2018-11-02T02:25:47 < catphish> i mean, i really don't like them, i don't like talking to them, i don't like the mess, i don't like the cost, i don't like the disruption
2018-11-02T02:26:04 < catphish> it would be insane to think that they'd be different
2018-11-02T02:26:23 < aandrew> catphish: how old are you? not an insinuation of anything, just asking
2018-11-02T02:26:34 < catphish> i'm 31
2018-11-02T02:27:16 < catphish> and i've made the decision with my wife this year that we're definitely never having children, we both can't tolerate them
2018-11-02T02:27:39 < catphish> i've always known, but now i feel like i'm old enough to be sure
2018-11-02T02:27:43 < aandrew> interesting
2018-11-02T02:27:50 < aandrew> yeah I've got six myself
2018-11-02T02:28:02 < catphish> wow :)
2018-11-02T02:28:09 < aandrew> had 2 when I was 23, 2nd wife had two before me, we had two together
2018-11-02T02:28:17 < aandrew> so we have kids from 23y to 6y
2018-11-02T02:28:17 < catphish> i get why some people would like them, personally i love cats
2018-11-02T02:28:31 < aandrew> I can say with 100% conviction that having kids before you're ~30yo is a mistake
2018-11-02T02:28:38 < aandrew> you're still a kid yourself no matter how mature you think you are
2018-11-02T02:28:46 < catphish> but i just can't stand children, mostly the chaos and mess
2018-11-02T02:28:47 < aandrew> somewhere around 30 you unlock another part of your brain
2018-11-02T02:28:57 < catphish> we're both kinda mess-phobic
2018-11-02T02:29:02 < aandrew> catphish: sure, some are like that and there's nothing wrong with it
2018-11-02T02:29:02 < jadew> catphish, I think having a kid is part of that maturization and probably why you think that
2018-11-02T02:29:11 < jadew> sorry, I meant aandrew
2018-11-02T02:29:13 < MrMobius> there is also the studies that show that people are not any happier in the moment taking care og children but their overall lifr satisfaction is much higher
2018-11-02T02:29:20 < MrMobius> on average
2018-11-02T02:29:20 < aandrew> jadew: I dont' think so
2018-11-02T02:29:46 < jadew> aandrew, I think it has changed me a lot
2018-11-02T02:29:54 < aandrew> I say that because in my 20s I could not properly empathize with the kid. e.g. I've fed you, your diaper's dry, you're not sweaty, GO THE FUCK TO SLEEP
2018-11-02T02:29:56 < jadew> having to worry about the future of someone else
2018-11-02T02:29:56 < catphish> there are unfortuntely people who don't like their own children, and i don't want to be one of them
2018-11-02T02:30:28 < aandrew> but around 30 it's more like "sigh, ok it's gonna be a night like this. and you cuddle up with them and that's it. you can just know they aren't doing it to you they're not in control

2018-11-02T02:30:41 < aandrew> my last two are certified geniuses too
2018-11-02T02:30:53 < aandrew> the 6yo is in mensa, 9yo was shy by 3 iq points
2018-11-02T02:31:11 < aandrew> it's a challenge, but it's fucking awesome too
2018-11-02T02:31:16 < catphish> aandrew: never mind, you can kill that one and try again :)

2018-11-02T02:31:40 < aandrew> the 19 and 17yos are cool 
2018-11-02T02:31:58 < aandrew> between age ... 12 and somewhere around 19 it's a mess
2018-11-02T02:32:03 < aandrew> kids go crazy all over again
2018-11-02T02:32:07 < aandrew> it's a medical fact
2018-11-02T02:32:26 < catphish> they are supposed to be horrible when they're 13-18
2018-11-02T02:32:32 < aandrew> the neuronal connections just *explode* around age 2-3 and again in early teens
2018-11-02T02:32:37 < catphish> and when they're 2 :)
2018-11-02T02:32:43 < aandrew> yes, this is the reason behind it
2018-11-02T02:32:47 < catphish> that's just how humans are made :)
2018-11-02T02:32:52 < aandrew> basically the brain rewiring itself
2018-11-02T02:33:03 < aandrew> trying new things and reinforcing the new connections that seem to work well
2018-11-02T02:33:05 < catphish> yeah, testing everything
2018-11-02T02:33:30 < aandrew> but these two little boys are just amazing. they get into everything, but I would not want it any othe way.
2018-11-02T02:33:31 < catphish> i'll stick with cats
2018-11-02T02:33:43 < aandrew> I have 3 boys and 3 girls. the girls are cool and all but the boys... something about boys
2018-11-02T02:33:50 < aandrew> they are the future kings of the world and you can see it in their eyes
2018-11-02T02:34:02 < aandrew> girls don't have that same thing even though we raise them to be independent and strong
2018-11-02T02:34:48 < aandrew> my 19yo daughter and 6yo son are very much alike personality wise, as are my 17yo son and 9yo son
2018-11-02T02:34:53 < jadew> they're more daring I think
2018-11-02T02:34:56 < aandrew> like little clones to an extent in certain areas
2018-11-02T02:35:09 < aandrew> it's not a matter of risk taking

2018-11-02T02:39:11 < aandrew> there's a saying
2018-11-02T02:39:21 < aandrew> the more you know, the more you know you don't know
2018-11-02T02:39:49 < aandrew> and I'm 100% certain there are at least three phrases in romanian that have a similar message
2018-11-02T02:40:05 < jadew> there are
2018-11-02T02:40:22 < aandrew> one of my favourite romanian sayings is "the country is on fire and the old woman brushes her hair"
2018-11-02T02:40:45 < jadew> heh, that's one of the funny ones
2018-11-02T02:40:54 < aandrew> there are a lot of funny ones
2018-11-02T02:41:16 < aandrew> one of the very first ones my wife told me was something like "you should beat your wife every day. and if you don't know why, your wife will."
2018-11-02T02:41:56 < jadew> Romanian wisdom :P
2018-11-02T02:42:15 < jadew> "if two people tell you you're drunk, you should go to bed"
2018-11-02T02:43:06 < jadew> "don't shit where you live"
2018-11-02T02:43:26 < jadew> or where you're sleeping?
2018-11-02T02:43:31 < jadew> yeah, it's with the sleeping
2018-11-02T02:43:31 < aandrew> there's a german saying "don't shit in the water, for we will brew beer with it tomorrow"
2018-11-02T02:43:39 < jadew> haha
2018-11-02T02:43:44 < aandrew> in english that is "don't shit where you eat"
2018-11-02T02:43:56 < aandrew> there was something about ironing as well
2018-11-02T02:44:20 < aandrew> "a woman can always tell if her husband has a mistress because his shirts aren't ironed the same way" or something
2018-11-02T02:44:55 < jadew> didn't know that one
2018-11-02T02:45:01 < catphish> nobody does ironing in my house
2018-11-02T02:45:26 < jadew> everyone does in mine (except me)
2018-11-02T02:45:32 < catphish> lol
2018-11-02T02:45:50 < jadew> I just don't care if my clothes are ironed or not
2018-11-02T02:45:54 < catphish> neither of us has a job that needs flat clothes :)
2018-11-02T02:46:06 < aandrew> something to do with the fact that no two woman iron a shirt the same way, so it's a dead giveaway, presumably because it's a woman's job to iron even if she's a mistress? dunno
2018-11-02T02:46:30 < aandrew> by far still  my favourite is tu dem pisda muti
2018-11-02T02:46:38 < catphish> wouldn't the more obvious giveaway be that the wife wasn't asked to iron it at all?
2018-11-02T02:46:42 < jadew> "between two women it won't rain on you, but it's not going to be good either"
2018-11-02T02:47:01 < aandrew> and I'm rather proud of myself for conjugating that particular curse into something that made her blush in a restaurant
2018-11-02T02:47:10 < jadew> lol aandrew
2018-11-02T02:47:11 < aandrew> "tu dem puta tati"
2018-11-02T02:47:17 < catphish> mistress sounds like a good idea
2018-11-02T02:47:32 < jadew> it's du-te-n pizda måti"

2018-11-02T02:50:05 < aandrew> she does not find it very funny when she's already pissed with the kids 
2018-11-02T02:50:10 < catphish> jadew: yes
2018-11-02T02:50:24 < catphish> i assume they come from that region

2018-11-02T02:50:31 < jadew> nope

2018-11-02T02:52:49 < jadew> some of the gypsy chicks do look really good, but that's not a common occurence
2018-11-02T02:52:55 < jadew> and they get extra fat later in life
2018-11-02T02:52:58 < catphish> some of them have nice looking caravans and make stuff out of wood and tell stories
2018-11-02T02:53:09 < catphish> others (who we assume are irish) just steal everything
2018-11-02T02:53:22 < catphish> the reality is probably more complicated :)
2018-11-02T02:53:22 < aandrew> in jimbolia they have huge houses that are unfinished (no windows for example) and they camp out in the back yard and live there
2018-11-02T02:53:43 < jadew> haha, yeah, they tend to do that
2018-11-02T02:54:06 < catphish> but there are a few that still love in old wagons and people think they're cool
2018-11-02T02:54:46 < jadew> catphish, that's how well they've managed to integrate in the past couple of hundreds of years
2018-11-02T02:54:59 < catphish> indeed

2018-11-02T02:55:37 < jadew> I've read a story about hungarian gypsies where they were living in really bad conditions outside of a city so the government gave them pigs and seeds to start farming
2018-11-02T02:55:41 < aandrew> and I learned that I can communicate with my brothers in law just fine with enough palinca
2018-11-02T02:55:44 < jadew> they ate the pigs and sold the seeds :D
2018-11-02T02:56:22 < catphish> lol
2018-11-02T02:57:21 < jadew> it's a cultural thing... some have managed to integrate tho and are indistinguishable from anyone else, but many simply kept their traditions and shady way of life
2018-11-02T02:57:48 < jadew> I guess it takes a lot of time for a people to forget their own roots
2018-11-02T02:58:06 < jadew> because that's what's asked of them when you require them to integrate
2018-11-02T02:59:08 < aandrew> I disagree
2018-11-02T02:59:10 < aandrew> very strongly
2018-11-02T02:59:24 < aandrew> there's nothing about asking you to forget your roots when you're integrating
2018-11-02T02:59:44 < aandrew> I mean here we have very strong german and polish and romanian communities (in my city)
2018-11-02T02:59:46 < jadew> well, there kinda is, if your roots are conflicting with the culture you're integrating into
2018-11-02T02:59:53 < aandrew> we have the world's second biggest oktoberfest, for example
2018-11-02T03:00:17 < jadew> see, you wouldn't say those people are not integrated
2018-11-02T03:00:23 < aandrew> we preserve a lot of our cultural traditions, but it doesn't mean we refuse to learn the local language and customs
2018-11-02T03:00:32 < jadew> because integrated doesn't mean that they're exactly the same, it means they can live side by side peacefully
2018-11-02T03:00:50 < jadew> the reason you noticed romanians aren't fond of gypsies is because that didn't happen here
2018-11-02T03:00:51 < aandrew> but for example what's going on with a lot of this massive muslim migration is that they clump together and refuse to integrate
2018-11-02T03:00:59 < aandrew> that's wrong, IMO
2018-11-02T03:01:06 < aandrew> if you don't want to integrate you can stay where you were
2018-11-02T03:02:26 < aandrew> we have a large number of various churches/synagogues/temples, everyone tends to get along very well

2018-11-02T03:02:44 < aandrew> in fact I would argue that a large number of the muslim population also integrated very well
2018-11-02T03:03:03 < jadew> yeah, it's doable for sure, but the immigrants have to want that
2018-11-02T03:03:15 < aandrew> by and large though it's the new wave who are being offered the moon and refusing to do anything in return
2018-11-02T03:03:20 < aandrew> yes, 100% 
2018-11-02T03:03:23 < aandrew> they ahve to want it
2018-11-02T03:04:53 < jadew> the gypsies on the other hand have always seen us as suckers
2018-11-02T03:05:28 < jadew> if you see someone as an idiot, you don't want to be like them
2018-11-02T03:06:43 < jadew> I often wonedered what would it take to make everyone get along
2018-11-02T03:06:53 < jadew> it takes a shift in perspective on both sides

2018-11-02T03:08:17 < jadew> unfortunately, because this abrasiveness has been going on for so long, it's already part of our culture and it's going to be very difficult to fix
2018-11-02T03:08:44 < jadew> for example, little kids are threathened with "if you don't behave, the gypsies will take you"
2018-11-02T03:09:04 < aandrew> heh
2018-11-02T03:09:40 < jadew> funnily enough, I overheard once a gypsy kid being threathed with "if you don't behave, the cops will take you"
2018-11-02T03:11:50 < jadew> my kid doesn't even knows the word gypsy, doesn't even know people are of different races
2018-11-02T03:11:59 < jadew> tried to keep him away from all this nonsense

2018-11-02T03:14:17 < jadew> hehe, not yet, but he asked a soldering station, a power supply and a signal generator as his next presents
2018-11-02T03:14:31 < aandrew> perfect
2018-11-02T03:15:04 < jadew> yeah, soon enough I'll just sit back and relax and he'll do all the work :P
2018-11-02T03:15:07 < aandrew> I made an LED smiley face with my kid last year, very very very very very very very early intro to arduino shit

2018-11-02T12:59:31 < BrainDamage> I won't explain that
2018-11-02T12:59:48 < catphish> all the holes are the correct size i believe
2018-11-02T12:59:58 < BrainDamage> I'm sorry for you
2018-11-02T13:00:05 < catphish> except maybe the camera, not sure if they're m2 or m2.5
2018-11-02T13:00:32 < catphish> all the others are correct, and not really my choice since they have to mount to existing hardware
2018-11-02T13:01:00  * catphish had to google onahole

2018-11-02T13:04:35 < BrainDamage> Thorn: at 1:25 you can see the left rocket not detaching properly
2018-11-02T13:10:27 < Thorn> more curiously, this video may show the moment of the assembly error that lead to the failure https://www.youtube.com/watch?v=lRQFl3U_Lsk

2018-11-02T13:31:27 < englishman> so does he post on 8chan
2018-11-02T13:31:53 < cjbaird> englishman: I was thinking getting plain IDC cable and coating it in soldering ink. :P :)
2018-11-02T13:34:43 < BrainDamage> cjbaird: why would you want such cursed item?
2018-11-02T13:37:15 < cjbaird> Digital busses (LCD, etc.) inside the ubitx. Parasitic oscillations make regular ribbon cable inside a superhet radio an issue. Adding enough resistance to critically damp the LC is the way to fix it.
2018-11-02T13:38:13 < BrainDamage> I regret asking
2018-11-02T13:38:17 < cjbaird> Old microcomputers often had that fucking-awful-to-deal-with solder-paste ink cables (for keyboards and etc)

2018-11-02T15:19:09 < dongs> so its ok

2018-11-02T15:20:02 < zyp> older bricks have more experience
2018-11-02T15:20:09 < Laurenceb124> but they all look shit and fake

2018-11-02T15:21:49 < dongs> bang cock
2018-11-02T15:23:33 < catphish> woo, my ISP just emailed to ask if i want to upgrade to 1000/100 :)
2018-11-02T15:23:37 < catphish> how about yes :)
2018-11-02T15:23:45 < zyp> what do you have now?
2018-11-02T15:23:49 < catphish> 100/50
2018-11-02T15:23:59 < zyp> will you even notice the difference? :p
2018-11-02T15:24:03 < catphish> unlikely
2018-11-02T15:24:14 < catphish> 100/50 was the fastest they did when i got it, which is plenty really
2018-11-02T15:24:33 < catphish> then they introduced 350/35, and i told them i didn't want less upload speed
2018-11-02T15:24:43 < catphish> but 1000/100 sounds lovely
2018-11-02T15:25:37 < zyp> I've got 500/500 now, the difference past 100Mb/s isn't very noticable
2018-11-02T15:25:50 < sync> 1000/1000 would be ok
2018-11-02T15:25:57 < sync> currently I'm on 100/40 :/
2018-11-02T15:25:59 < zyp> or rather, right now I have 0/0, shit failed yesterday
2018-11-02T15:26:44 < zyp> not sure if people tore off the fiber or what, GPON box says it's not getting an optical signal
2018-11-02T15:27:49 < zyp> possibly, there were some workers playing in the manholes in the street yesterday morning
2018-11-02T15:28:01 < zyp> but they weren't there when I got home from work, and internet still worked then
2018-11-02T15:28:09 < zyp> failed a bit after I got home
2018-11-02T15:28:23 < sync> maybe your internet pipe developed a leak after they stepped on it
2018-11-02T15:28:27 < catphish> i could get 1000/1000 from my ISP, but if you want anything but 10:1 U/D ratio you have to pay 10x more and get their "leased line" service with the associated SLA etc
2018-11-02T15:29:46 < catphish> one thing i will be doing is shifting my home CCTV into the cloud
2018-11-02T15:29:56 < zyp> the contract I signed for new house is "only" 150/150, but ISP should be more decent than the one I have now
2018-11-02T15:29:56 < catphish> then i don't need to run a server at home to record
2018-11-02T15:30:07 < catphish> 150/150 sounds plenty decent
2018-11-02T15:30:21 < catphish> i have literaly no idea what i'll do with a gigabit
2018-11-02T15:30:31 < zyp> yeah, I don't think going from 500/500 to 150/150 will be noticeable at all
2018-11-02T15:30:35 < catphish> for some reason the ISP claims that no consumer needs more than 10:1 U/D ratio
2018-11-02T15:30:42 < zyp> maybe torrents will run a bit slower, but I don't torrent very often
2018-11-02T15:30:42 < catphish> and yet they sell gigabit down speeds
2018-11-02T15:31:06 < catphish> i'm really only getting it for the 100Mbit up speed
2018-11-02T15:31:25 < zyp> makes sense
2018-11-02T15:31:42 < sync> yeah, I could get 350/40, but fuck that
2018-11-02T15:32:21 < zyp> nice, technician just called, he's on his way to my house now
2018-11-02T15:32:28 < zyp> guess I'll go meet him then

2018-11-02T16:13:57 < englishman> they are offering 1500/940 here now
2018-11-02T16:14:28 < englishman> but when i had 1000/900 a few years ago they could not keep up at the backend
2018-11-02T16:14:41 < englishman> would drop to 30mbps every evening without fail
2018-11-02T16:15:14 < englishman> so they add "Assuming optimal network conditions" all over the contracts
2018-11-02T16:16:31 < Steffanx> 1500/900 why?
2018-11-02T16:20:11 < Steffanx> Idk what that means

2018-11-02T16:30:08 < englishman> a router
2018-11-02T16:30:29 < catphish> i gess yeah, if it has the right interface :)
2018-11-02T16:31:08 < catphish> my connection is ethernet, if i want to go faster than 1G it would need to be upgraded to 10G
2018-11-02T16:31:16 < englishman> and so it shall be
2018-11-02T16:31:24 < catphish> and i don't have any 10G routers spare :)

2018-11-02T16:46:25 < leachim6> so I'm a little confused
2018-11-02T16:46:35 < leachim6> sure you can program the stm32 in the arduino IDE
2018-11-02T16:46:39 < leachim6> but is there an official IDE?
2018-11-02T16:46:41 < leachim6> https://www.st.com/en/development-tools/stm32-ides.html?querycriteria=productId=LN1200
2018-11-02T16:46:43 < leachim6> like atmel studio but less ass ?
2018-11-02T16:47:46 < mawk> if you don't see an IDE with vendor ST in that list then no
2018-11-02T16:48:02 < mawk> you can use gcc, make and your favorite text editor
2018-11-02T16:48:56 < zyp> fucking technician didn't bring a fusion splicer
2018-11-02T16:48:58 < leachim6> soemthing like this -> https://github.com/nitsky/stm32-example/blob/master/Makefile

2018-11-02T16:52:35 < mawk>  what ?
2018-11-02T16:52:37 < mawk> yes
2018-11-02T16:52:58 < leachim6> I've used it to xcompile for raspberry pi before, but wasn't sure if all ARM was created equal in that respect
2018-11-02T16:53:26 < mawk> that's a suboption to gcc
2018-11-02T16:53:29 < mawk> don't worry
2018-11-02T16:53:31 < jpa-> usually for raspberry pi, you'd use arm-linux-eabi-gcc

2018-11-02T16:54:28 < leachim6> they're so cheap I had to try them

2018-11-02T16:55:52 < kakimir> and I want to convert vcc to voltage reading
2018-11-02T16:57:03 < kakimir> I don't know the vcc to correct reference voltage
2018-11-02T16:57:07 < mawk> the reference depends on Vcc kakimir ? that seems antinomic
2018-11-02T16:57:17 < kakimir> it's normal?
2018-11-02T16:57:33 < kakimir> also temperature!
2018-11-02T16:57:47 < mawk> that seems even more antinomic
2018-11-02T16:58:02 < mawk> or we're not talking about the same bandgap reference thing
2018-11-02T16:58:55 < BrainDamage> the whole point of a bandgap reference is that it changes extremely little with temperature and supply
2018-11-02T16:59:05 < BrainDamage> fixed by the ... bandgap of the material
2018-11-02T16:59:19 < BrainDamage> it's the combination of a PTAT to a CTAT
2018-11-02T16:59:52 < kakimir> I have 128bytes of ram
2018-11-02T16:59:55 < BrainDamage> if anything, you should compare your supply to the bandgap
2018-11-02T17:00:19 < kakimir> I wonder how this will go down when I use this interpolation thing
2018-11-02T17:00:39 < BrainDamage> congratulations, you've managed to make even less sense than usual
2018-11-02T17:00:52 < kakimir> bandgap voltage changes with supply!
2018-11-02T17:01:11 < mawk> a reference that changes with supply doesn't deserve the name reference
2018-11-02T17:01:28 < kakimir> there is no ideal reference
2018-11-02T17:01:44 < mawk> yeah but with a bandgap reference we're talking about a very small change with supply
2018-11-02T17:01:48 < mawk> you wouldn't mention it at all
2018-11-02T17:02:34 < kakimir> attiny20 datasheet page 197
2018-11-02T17:02:48 < kakimir> figure 21-45.
2018-11-02T17:03:12 < kakimir> operating range for the device is 4.0 - 5.5volts
2018-11-02T17:03:56 < kakimir> temperature range for electronics in operation something like -5C - 70C
2018-11-02T17:04:13 < mawk> yes
2018-11-02T17:04:17 < mawk> see the vertical scale
2018-11-02T17:04:33 < kakimir> yes
2018-11-02T17:04:39 < mawk> you could always get a better reference chip if it's not enough
2018-11-02T17:04:53 < kakimir> this is consumer electronics
2018-11-02T17:05:14 < BrainDamage> it changes by 10mV over the span of 60°C
2018-11-02T17:05:24 < BrainDamage> I would call it pretty fucking decent
2018-11-02T17:05:55 < BrainDamage> if you want better, you need buried zeners with bolometers
2018-11-02T17:06:56 < kakimir> okay assume then that you have voltage change between 4-5.4 and temperature change from 0-80
2018-11-02T17:07:02 < kakimir> and check worst case
2018-11-02T17:07:25 < kakimir> and 4 - 5.5V*
2018-11-02T17:07:41 < BrainDamage> just draw a rectangle over the graph over your operative ranges
2018-11-02T17:07:47 < BrainDamage> and you'll know the voltage margins
2018-11-02T17:08:01 < kakimir> yes
2018-11-02T17:08:12 < kakimir> all I know is that it means whole percents
2018-11-02T17:08:18 < kakimir> many percents
2018-11-02T17:08:44 < BrainDamage> if you need better stability, either regulate better your supply or the chip's temp, or use an external reference
2018-11-02T17:08:51 < BrainDamage> no magic tricks
2018-11-02T17:09:01 < kakimir> cannot do and cannot do
2018-11-02T17:09:12 < kakimir> hard way - my way
2018-11-02T17:09:54 < kakimir> I should simplify my interpolation to one temperature range not 2
2018-11-02T17:09:57 < englishman> if you want a better reference then you buy a better reference
2018-11-02T17:09:59 < mawk> if you carry the computation to the end what's the error on Vcc with that ±3.7% change in reference ?
2018-11-02T17:10:05 < kakimir> englishman: I do workaround
2018-11-02T17:10:26 < BrainDamage> you cannot workaround without a more precise reference
2018-11-02T17:10:38 < BrainDamage> against what you'd measure your supply, to know it's off?
2018-11-02T17:10:42 < kakimir> mawk: way more than 100mV
2018-11-02T17:10:56 < kakimir> but hey I have plan
2018-11-02T17:11:15 < kakimir> iterate bandgap with multiple vcc measurements
2018-11-02T17:11:30 < kakimir> calculate new bandgap every time
2018-11-02T17:11:32 < mawk> what for ?
2018-11-02T17:11:38 < BrainDamage> and how can you measure your vcc?
2018-11-02T17:11:48 < kakimir> with fixed value first
2018-11-02T17:11:51 < BrainDamage> using the bangap?
2018-11-02T17:12:01 < kakimir> 1.07V fixed value
2018-11-02T17:12:10 < BrainDamage> ... that's the bandgap
2018-11-02T17:14:03 < kakimir> I don't even need to know exact VCC
2018-11-02T17:14:15 < englishman> in engineering, noone does
2018-11-02T17:14:17 < kakimir> but I need good bandgap value to measure another thing
2018-11-02T17:14:50 < kakimir> I mean stuff needs to be accurate as shit
2018-11-02T17:14:58 < kakimir> attiny20 will do it
2018-11-02T17:15:09 < englishman> why no stm8
2018-11-02T17:16:49 < kakimir> what is the smallest package it has?
2018-11-02T17:17:01 < englishman> 3x3 qfn20
2018-11-02T17:17:14 < englishman> maybe some wlscp idk
2018-11-02T17:20:09 < bitmask> when checking battery capacity, what is the voltage range for li-ion
2018-11-02T17:20:21 < kakimir> 2.5 - 4.2
2018-11-02T17:20:46 < bitmask> 2.5 huh, thought that was lower than recommended, I dont think my charger goes below 3.2
2018-11-02T17:20:56 < bitmask> that would explain my low readings though
2018-11-02T17:20:57 < kakimir> most of undervoltage protections cut power around 3
2018-11-02T17:21:16 < kakimir> 2.75 is common too
2018-11-02T17:21:22 < bitmask> alright thanks
2018-11-02T17:21:34 < kakimir> 3.2 is concervative and under high load
2018-11-02T17:21:51 < kakimir> depends on how much load you have etc. etc.
2018-11-02T17:22:32 < bitmask> load isnt too bad, probably gonna be around 2A split between 9 batteries (3s3p) and they are at least 10A but mostly 20A rated
2018-11-02T17:23:21 < bitmask> wish I had higher capacity but cant complain since I'm repurposing what I already had
2018-11-02T17:23:40 < kakimir> so 0.667A per cell
2018-11-02T17:23:45 < kakimir> 18650?
2018-11-02T17:23:51 < bitmask> yea
2018-11-02T17:24:04 < bitmask> used em for vaping, now I want to use em to power my heated hoodie
2018-11-02T17:24:04 < kakimir> high-current cell?
2018-11-02T17:24:07 < bitmask> yea
2018-11-02T17:24:14 < kakimir> okay 0.667A is nothing
2018-11-02T17:24:17 < bitmask> yea I know
2018-11-02T17:24:49 < kakimir> check lygte-info and datasheet of the cell
2018-11-02T17:25:24 < bitmask> like I said, most are rated for 20A continuous with only two being rated for 10A continuous, thats not a concern
2018-11-02T17:25:46 < bitmask> or did you mean for voltage
2018-11-02T17:25:56 < bitmask> I forgot what we were talking about :P
2018-11-02T17:26:02 < kakimir> some cells are practically empty like before 3V
2018-11-02T17:26:18 < bitmask> I see
2018-11-02T17:26:22 < kakimir> some cells have juice left under 3V
2018-11-02T17:26:33 < kakimir> depends on chemistry used etc.
2018-11-02T17:31:55 < kakimir> are you mixing cells?
2018-11-02T17:32:07 < kakimir> can the pack keep balance?
2018-11-02T17:32:46 < bitmask> I'm keeping same cells in series but different series packs in parallel
2018-11-02T17:32:58 < kakimir> good
2018-11-02T17:33:10 < kakimir> I would test it
2018-11-02T17:33:10 < bitmask> and I"ll balance charge them
2018-11-02T17:33:14 < kakimir> okay
2018-11-02T17:33:26 < bitmask> and use undervoltage protection circuit
2018-11-02T17:33:30 < kakimir> per cell monitoring for discharge?
2018-11-02T17:33:40 < bitmask> yes
2018-11-02T17:33:52 < bitmask> each series pack will get one of these (one sec getting link)
2018-11-02T17:34:23 < bitmask> https://www.ebay.com/itm/Protection-Board-Lithium-Battery-Charger-BMS-Li-ion-Charging-Module-3S-10A-12V/282425763237

2018-11-02T22:53:43 < PaulFertser> aandrew: I'd bet it's just an imitation, not port.
2018-11-02T22:54:14 < aandrew> I think it was x11's code, not 100% sure though
2018-11-02T22:54:21 < aandrew> I haven't loaded xquartz on this machine lately
2018-11-02T22:54:28 < PaulFertser> Yep, my point.

2018-11-02T22:55:06 < PaulFertser> Of course, X11 is not "linux" but I hoped kakimir didn't notice ;)
2018-11-02T22:57:41 < zyp> how about xconfig?
2018-11-02T22:57:49 < zyp> (as in «make xconfig»)
2018-11-02T22:58:52 < zyp> I might be wrong, but I've only ever seen that run on linux for linux
2018-11-02T22:58:59 < PaulFertser> Heh :) not sure if iconic enough but it is "for linux" indeed. In an interesting way too, that is, even if you run it on some other OS it's still "for linux".
2018-11-02T23:00:07 < PaulFertser> I know people are building OpenWrt on OS X, and it uses all the Linux Kconfig infra, I wouldn't be surprised to see xconfig working there too.
2018-11-02T23:00:57 < zyp> sounds like we need to find some closed source shit that's only built for linux
2018-11-02T23:01:08 < zyp> because anything opensource gets ported all over the place anyway
2018-11-02T23:01:31 < karlp> hehe, friend was using tanner (https://www.mentor.com/tannereda/ams-ic) the other day, the linux package.
2018-11-02T23:01:42 < karlp> turns out it was just wine, packaged up :)
2018-11-02T23:02:22 < zyp> there were some company that were doing OS X games some years ago
2018-11-02T23:02:29 < zyp> which was also just packaged up wine
2018-11-02T23:02:41 < zyp> IIRC EVE Online used that
2018-11-02T23:04:28 < BrainDamage> bleh, I can't find it anymore, but there was a program that rendered random moe anime girls on your desktop

2018-11-02T23:23:59 < PaulFertser> What is the rationale for returning 0 by default for "divide by zero" when the corresponding exception is not enabled?
2018-11-02T23:24:42 < kakimir> to at least return something?
2018-11-02T23:24:58 < kakimir> what should it return?
2018-11-02T23:25:07 < kakimir> 0xFF.. ?
2018-11-02T23:26:29 < PaulFertser> kakimir: yes, I'd prefer it to return maximum value (signed or unsigned depending on sdiv/udiv).
2018-11-02T23:27:02 < kakimir> it would be usable in some cases
2018-11-02T23:28:08 < Thorn> https://www.youtube.com/watch?v=GEJhb93rKlU
2018-11-02T23:28:32 < PaulFertser> My question is when 0 would be preferrable?
2018-11-02T23:30:35 < renn0xtk9> I have read that ST has abandonned the Std Peripheral Library
2018-11-02T23:30:50 < renn0xtk9> does that mean that it is a really bad idea to star tlearning STM32 with it?
2018-11-02T23:30:59 < renn0xtk9> I have also read that HAL is very buggy
2018-11-02T23:31:04 < renn0xtk9> so I don't know what to do 
2018-11-02T23:31:51 < PaulFertser> renn0xtk9: libopencm3 if you like C
2018-11-02T23:34:49 < renn0xtk9> PaulFertser on their github the readme says it should not yet be considered stable
2018-11-02T23:35:01 < renn0xtk9> whatever it can mean
2018-11-02T23:35:39 < PaulFertser> renn0xtk9: it's free software, you can check the log to see how stable it is. And contribute to it when you need to add new features.
2018-11-02T23:35:44 < Steffanx> renn0xtk9, there is also the "low level" stuff that comes with the ST HAL
2018-11-02T23:35:51 < Steffanx> The ll_* files.
2018-11-02T23:35:59 < Steffanx> Its kinda like the old peripheral lib
2018-11-02T23:36:34 < Steffanx> and they have many examples using the "ll" functions too.

2018-11-02T23:41:09 < BrainDamage> aw, turns out I was wrong, the program runs on windows too
2018-11-02T23:41:13 < BrainDamage> it's macopix
2018-11-02T23:44:12 < renn0xtk9> so basicallly I clone the git, I make install it , and then I just got the include headers and link to the library and I can get going?
2018-11-02T23:46:59 < PaulFertser> renn0xtk9: for libopencm3 I'd suggest to start with cloning libopencm3-examples
2018-11-02T23:48:50 < karlp> PaulFertser: I told him to start with libopencm3-miniblink to test his toolchain
2018-11-02T23:49:20 < karlp> I had a little hiccup withthe submoudle usinga  git url instead of a https url so it ddidn't work for people without github credentials though, but I fixed that and then enver head back
2018-11-02T23:49:32 < PaulFertser> karlp: oh, I see.
2018-11-02T23:49:40 < karlp> never heard back sorry.
2018-11-02T23:50:00 < PaulFertser> Any idea when returning 0 is really better than MAX_INT?
2018-11-02T23:50:11 < karlp> the other alternative for testing your toolchain and flashing tools are cubemx generated code.
2018-11-02T23:50:12 < PaulFertser> (in /0 case)
2018-11-02T23:50:16 < renn0xtk9> yeah was at work, only play with stm32 on my spare time:S
2018-11-02T23:50:29 < karlp> renn0xtk9: not stable just menas we might change some apis,
2018-11-02T23:50:36 < renn0xtk9> okay
2018-11-02T23:50:45 < karlp> it's actually stable and we change apis very rarely, and normally keep backwards compat
2018-11-02T23:51:06 < karlp> there's also a libopencm3-template repo
2018-11-02T23:51:26 < renn0xtk9> cubemx means it generates the project for you but then you have to use HAL no?
2018-11-02T23:51:48 < renn0xtk9> I will try libopencm3 tomorrow it is late now 
2018-11-02T23:52:08 < renn0xtk9> what I want to have ultimately is an agiel toolchain
2018-11-02T23:52:19 < mawk> you can also use the LL thing Steffanx was talking about, with cubemx
2018-11-02T23:52:41 < mawk> maybe you heard HAL to be very buggy but for the little I've used it for I've never noticed such thing
2018-11-02T23:52:46 < renn0xtk9> that I cann jumpstart a project within seconds, not having to worry about hardware peculiarities issue, focussing on cod efrom second one
2018-11-02T23:52:49 < karlp> renn0xtk9: yes, but you need to work on your goals,
2018-11-02T23:52:50 < mawk> cubemx was buggy for sure, but in recent versions it seems fixed
2018-11-02T23:52:57 < karlp> do you want to test your toolchain and your hardware? 
2018-11-02T23:53:08 < karlp> and what on earth is an "agile toolchain" ?
2018-11-02T23:53:22 < karlp> if you like words like that, have you tried arduino?
2018-11-02T23:53:29 < karlp> it supports stm32 boards rather well now too.
2018-11-02T23:53:32 < mawk> with cubemx I "jumpstart" a project in seconds like you say
2018-11-02T23:53:32 < PaulFertser> renn0xtk9: probably you need ChibiOS then? Or even mbed or orduino?
2018-11-02T23:53:33 < karlp> also mbed,
2018-11-02T23:53:40 < mawk> it compiles right ouf of the box

2018-11-03T00:18:29 < englishman> congrats!
2018-11-03T00:18:37 < ac_slater> I'm trying the UART example and it's mapping USART3 TX to Pd8 and USART3 TX to Pd9
2018-11-03T00:18:42 < mawk> you know how to flash it renn0xtk9 ?
2018-11-03T00:19:00 < ac_slater> but, someone said USART3 might be over STLINK? Super confused
2018-11-03T00:19:31 < ac_slater> I tried to put a TTL-USB converter on those pins and receive no data, obviously. My main loop just sleeps then prints a string
2018-11-03T00:19:32 < englishman> what does it show in the NUCLEO-F746ZG schematic for pd8 and pd9?
2018-11-03T00:19:41 < mawk> one of the uarts is over the stlink yes
2018-11-03T00:19:52 < mawk> just pick another one if you don't want that
2018-11-03T00:20:03 < mawk> or keep it and look through the usb cable and not the ttl converter
2018-11-03T00:20:03 < ac_slater> I can't tell if USART3 is the one over the STLINK
2018-11-03T00:20:16 < mawk> it's in the datasheet
2018-11-03T00:20:34 < ac_slater> I tried to use the same connection I use with openocd, but no dice
2018-11-03T00:20:39 < ac_slater> ie - ttyACM0
2018-11-03T00:20:42 < englishman> or in the user manual
2018-11-03T00:20:45 < mawk> yes, ttyACM0
2018-11-03T00:20:54 < mawk> and how do you use that ?
2018-11-03T00:20:57 < ac_slater> hmm interesting. That was my initial though
2018-11-03T00:20:59 < mawk> you use minicom -D /dev/ttyACM0 ?
2018-11-03T00:21:07 < ac_slater> I use `tio`, but yea minicom will work
2018-11-03T00:21:13 < ac_slater> the example has a weird non-8N1 config
2018-11-03T00:21:18 < mawk> and you have the right parameters .
2018-11-03T00:21:18 < renn0xtk9> mawk well I thought I knew (i.e. st-flash write foobar.bin 0x8000000)
2018-11-03T00:21:18 < mawk> ?
2018-11-03T00:21:19 < mawk> ah
2018-11-03T00:21:29 < mawk> yes renn0xtk9 like that
2018-11-03T00:21:32 < ac_slater> so I just use `tio -b 9600 -d 7 -s 1 -f off -p odd`
2018-11-03T00:21:37 < renn0xtk9> but it tells me 2018-11-02T23:19:57 ERROR common.c: map_file() == -1
2018-11-03T00:21:44 < ac_slater> (with the device in there too of course)
2018-11-03T00:21:45 < renn0xtk9> by the way there is an error in thre readme
2018-11-03T00:21:46 < mawk> that's a strange error
2018-11-03T00:22:08 < renn0xtk9> the readme says $ st-flash write path/to/yourfile.bin 0x800000     (< a zero is lacking here)
2018-11-03T00:22:42 < mawk> 0x08000000
2018-11-03T00:23:22 < renn0xtk9> I have a Stlink V2 and I compile the code from https://github.com/texane/stlink to get st-flash st-util and stuff
2018-11-03T00:23:28 < mawk> ah
2018-11-03T00:23:43 < mawk> I just used the one from the debian repo
2018-11-03T00:23:49 < mawk> stlink-tools package
2018-11-03T00:23:54 < mawk> there is also a GUI if you want
2018-11-03T00:24:43 < renn0xtk9> mawk you know the package name and wether available for ubuntu too?
2018-11-03T00:24:59 < mawk> stlink-tools
2018-11-03T00:25:07 < mawk> but it's the same thing probably
2018-11-03T00:25:47 < renn0xtk9> mawk yes but maybe a former version which works better (I had a code working last year, and flashing same code with same board does not work anymore)
2018-11-03T00:25:54 < ac_slater> So, I found the place in the user manual where it explains USART3. But shit it's confusing. https://www.st.com/content/ccc/resource/technical/document/user_manual/group0/26/49/90/2e/33/0d/4a/da/DM00244518/files/DM00244518.pdf/jcr:content/translations/en.DM00244518.pdf
2018-11-03T00:26:03 < renn0xtk9> I slowely start to suspect some regression in that texane thing
2018-11-03T00:26:03 < ac_slater> section 6.9 (literally 100 words of explaination)
2018-11-03T00:27:45 < ac_slater> wtf is a morpho connector
2018-11-03T00:28:05 < mawk> it's the regular pins on your board
2018-11-03T00:28:19 < mawk> so yeah it's USART3 that's going to the stlink
2018-11-03T00:28:33 < karlp> renn0xtk9: thanks for reporting the missing 0, I've fixed that now.
2018-11-03T00:28:49 < renn0xtk9> karlp welcome
2018-11-03T00:29:04 < karlp> (I don't use texane, so I'd just hand written the line)
2018-11-03T00:30:27 < renn0xtk9> yeah no worries, actually I had a small dopamine shot believing that the Readme was right and that all my problems were simply me adding a 0 all the time. Sadly it was the other way around ^^
2018-11-03T00:31:25 < mawk> it works better with the repo version renn0xtk9 
2018-11-03T00:31:26 < mawk> ?
2018-11-03T00:31:30 < mawk> you used the git master ? let me try
2018-11-03T00:31:47 < mawk> usually you want to checkout to a stable release at least, or a release candidate
2018-11-03T00:31:54 < renn0xtk9> mawk i am still searchin, on ubunut stlink-tools is not in the repo
2018-11-03T00:31:55 < mawk> but the git master may not compile or be fully clean
2018-11-03T00:31:59 < mawk> I see
2018-11-03T00:32:15 < renn0xtk9> and first I want to analyze which version they use in repo once I have find it

2018-11-03T00:34:13 < mawk> what to you mean via the stlink connector ac_slater ? you're supposed to do it from your computer with /dev/ttyACM0
2018-11-03T00:34:29 < ac_slater> mawk: yea I know. But I mean, I only have one cable
2018-11-03T00:34:33 < ac_slater> I think I forgot syscalls.c
2018-11-03T00:34:49 < mawk> you only need one cable
2018-11-03T00:35:02 < mawk> it's the same cable for programming and tallking with virtual console port
2018-11-03T00:35:11 < mawk> and that cable goes to the stlink
2018-11-03T00:35:20 < mawk> the stlink programs, provides power and clock, and provides a UART
2018-11-03T00:37:07 < ac_slater> yea I figured it put
2018-11-03T00:37:09 < ac_slater> out * 
2018-11-03T00:37:18 < ac_slater> I didnt take the __io_putchar overload from the example

2018-11-03T00:37:46 < ac_slater> I couldnt figure out how the VCP works, but the fact that it's an ACM device is a hint that it's a bit implicit

2018-11-03T00:43:36 < renn0xtk9> well lsusb says Bus 001 Device 011: ID 0483:3748 STMicroelectronics ST-LINK/V2 and 2018-11-02T23:40:52 WARN usb.c: Couldn't find matched ST-Link/V2 devices
2018-11-03T00:44:00 < mawk> uh
2018-11-03T00:44:07 < mawk> you have a stlink v2 ? 
2018-11-03T00:44:24 < renn0xtk9> yeah
2018-11-03T00:44:32 < renn0xtk9> I mean in my understanding it is a clone
2018-11-03T00:44:37 < renn0xtk9> but it used to work befofre
2018-11-03T00:44:39 < mawk> yes it's a clone
2018-11-03T00:44:42 < mawk> apparently
2018-11-03T00:44:53 < mawk> but it programs successfuly ?
2018-11-03T00:45:09 < mawk> apart from that warning
2018-11-03T00:45:51 < mawk> I have the same bluepill as you but I use a stlink V2.1 to program it
2018-11-03T00:46:31 < renn0xtk9> It uses to say jolly good when it finishes now i dont see anything 
2018-11-03T00:46:56 < karlp> yeah, I think someone finally removed that line ;)
2018-11-03T00:47:06 < renn0xtk9> :S was nice
2018-11-03T00:47:22 < mawk> I still have it with the latest version
2018-11-03T00:47:28 < mawk> so something might be wrong on your side renn0xtk9

2018-11-03T00:47:50 < renn0xtk9> mawk no blinking led
2018-11-03T00:48:08 < mawk> what's the total output ? put on a pastebin
2018-11-03T00:48:18 < mawk> you use 0x08000000 as the flash address right ?
2018-11-03T00:48:19 < oz4ga> kein blinkenlightz verdamt!
2018-11-03T00:48:24 < mawk> lol
2018-11-03T00:48:26 < karlp> hrm, git log doesn't say jolly good was removed,
2018-11-03T00:48:34 < karlp> so... you still have other problems.
2018-11-03T00:48:44 < mawk> you have other serial devices on the system renn0xtk9 ? maybe try to specify path to /dev/ttyACM0
2018-11-03T00:48:56 < karlp> renn0xtk9 shoujldn't be using a serial device
2018-11-03T00:49:07 < karlp> ac_slater might have, but not renn
2018-11-03T00:49:23 < renn0xtk9> https://pastebin.com/SxfXsx0d all wha tI see
2018-11-03T00:49:37 < karlp> heh, jolly good started back in 2011
2018-11-03T00:50:01 < renn0xtk9> no nothing on ACM0
2018-11-03T00:50:18 < karlp> (try sudo to check whether you have perms issues or not)
2018-11-03T00:50:28 < renn0xtk9> there is nothing I should change in the code right? I mean to taget the "PC13" LED
2018-11-03T00:50:38 < renn0xtk9> code should work as is for the blue pill
2018-11-03T00:51:11 < karlp> yes.
2018-11-03T00:51:13 < karlp> it's not flashing
2018-11-03T00:51:17 < karlp> you didnt' get jolly good
2018-11-03T00:51:26 < mawk> use sudo
2018-11-03T00:52:04 < renn0xtk9> Oh shit ! that did and it blink ! ;)
2018-11-03T00:52:55 < karlp> yeah, you have a perms issue still.
2018-11-03T00:53:04 < karlp> hrm, does lcsc sell  cards?
2018-11-03T00:53:07 < karlp> sell sd cards?
2018-11-03T00:53:39 < karlp> hrm, what else shoudl I buy from them...
2018-11-03T00:53:44 < oz4ga> could it be missing group membership?
2018-11-03T00:55:36 < renn0xtk9> thanks karlp and mawk
2018-11-03T00:55:48 < oz4ga> sudo and chmod 777 is like an president with a  gatling
2018-11-03T00:57:08 < mawk> for some devices yes group membership is an issue, but not here oz4ga 
2018-11-03T00:57:11 < renn0xtk9> oz4ga I thing tha tmust be but is is  not clear to me which group I  have to belong
2018-11-03T00:57:32 < mawk> here you need to issue raw usb commands, you need root
2018-11-03T00:57:32 < renn0xtk9> maybre something wrong with the udev rules I had to set for that st-link v2
2018-11-03T00:58:49 < renn0xtk9> that opencm3 seem pretty good though
2018-11-03T00:59:01 < mawk> I never tried, but it's on my list
2018-11-03T00:59:11 < mawk> I've only did baremetal with just the ST docs, and cubemx
2018-11-03T00:59:28 < mawk> you can try cubemx for comparison, you just choose Makefile as the toolchain
2018-11-03T00:59:32 < mawk> and you can choose between HAL and LL
2018-11-03T01:00:01 < mawk> it generates the initialization code for the PLL, clock, interrupt vector, GPIO banks, etc, so it's nice in that regard
2018-11-03T01:00:08 < mawk> but you may like or not like the HAL/LL interface
2018-11-03T01:00:18 < mawk> also until recently the generated makefile was pretty shitty
2018-11-03T01:00:22 < mawk> you had to rework it
2018-11-03T01:00:23 < oz4ga> LL !!! since they won't give us STL back :c
2018-11-03T01:01:00 < renn0xtk9> still not clear to me why my code that use to work does not anymore. Some folks have told me that I am not resetting the watchdog (IWDG) but I don t find where it is done in that example
2018-11-03T01:02:38 < mawk> you can use st-util to gdb your code
2018-11-03T01:02:40 < mawk> it's very easy
2018-11-03T01:02:49 < mawk> and you'll see where the processor is looping
2018-11-03T01:02:55 < mawk> if it's the IWDG interrupt handler, etc
2018-11-03T01:03:06 < mawk> at least if opencm provides a default interrupt handler for the IWDG interrupt, that is
2018-11-03T01:03:32 < karlp> oz4ga: groups are "legacy" modern distros are using tag+=uaccess normally now
2018-11-03T01:04:06 < karlp> renn0xtk9: if you have udev rules that added you to a group, but your distro doesn't use groups, they won't have done anything.
2018-11-03T01:04:44 < karlp> ATTRS{idVendor}=="0483", ATTRS{idProduct}=="374b", MODE="660", GROUP="plugdev", TAG+="uaccess" will do both...
2018-11-03T01:04:56 < karlp> (that's the PID for stlink v2.1...)
2018-11-03T01:05:23 < karlp> hrm, lcsc wants to charge $3 for oorders less than $15
2018-11-03T01:05:31 < mawk> that's pretty cheap
2018-11-03T01:05:46 < mawk> it's more like $20 for US/EU sites
2018-11-03T01:06:15 < renn0xtk9> yeah I don't have uacess in my rule
2018-11-03T01:07:43 < renn0xtk9> this being said,
2018-11-03T01:07:48 < renn0xtk9> thanks a lot for your help
2018-11-03T01:07:54 < renn0xtk9> but it is midnight here

2018-11-03T01:22:57 < karlp> more like digikey/mouser with more asian manufacturers
2018-11-03T01:23:19 < karlp> so things that used to be unobtainium without your own chinagirl are now purchaseable

2018-11-03T11:59:07 < antto> i have superlux hd668b .. cable goes into the left side, then there's no cable to the right one
2018-11-03T11:59:31 < antto> so i guess the two metal frames also carry the signal for the right one
2018-11-03T12:02:42 < antto> *shrug*
2018-11-03T12:05:45 < dongs> I'm OK with QC35s
2018-11-03T12:05:52 < Steffanx> Heh, didnt expect it to be THAT cheap antto :)
2018-11-03T12:06:33 < antto> i was recommended to get these by a friend.. he said they're surprisingly good for the price
2018-11-03T12:08:09 < Steffanx> But those costs like 10 times more dongs. Bose tax included
2018-11-03T12:08:22 < antto> the two things that come out which should sit on your head are nasty.. they're not soft and after like 20 minutes - it hurts.. but i removed them (elegantly) and now it's fine
2018-11-03T12:08:36 < antto> very nice that the cable can be unplugged

2018-11-03T12:21:49 < Steffanx> Id buy crt.
2018-11-03T12:22:32 < Steffanx> Or maybe the sony WH1000XM2
2018-11-03T12:23:00 < Steffanx> Perhaps.
2018-11-03T12:25:36 < antto> noise canceling?
2018-11-03T12:25:56 < Steffanx> Ya
2018-11-03T12:26:25 < antto> well, i needed headphones for "making music" so that has different goals
2018-11-03T12:27:01 < antto> the superlux are gud and cheap
2018-11-03T12:30:34 < Steffanx> Only conrad seems to sell them here. Heh
2018-11-03T12:32:09 < antto> similar to monitor speakers
2018-11-03T12:32:19 < Steffanx> Lolwut?
2018-11-03T12:33:04 < Steffanx> Dont tell crt
2018-11-03T12:36:34 < antto> Cracki flat frequency response (as much as possible) no "coloration" and fancy sh*t
2018-11-03T12:37:23 < antto> and potentially you wear them the whole day
2018-11-03T12:37:31 < antto> (or night)
2018-11-03T12:37:36 < PeterM> just get some sony mdr1000s
2018-11-03T12:38:07 < cjbaird> I've got a pair of MDR-180P that must be about 15 years old..
2018-11-03T12:38:35 < PeterM> yeah andd  they're still probably good
2018-11-03T12:38:46 < antto> for my mp3 player i use in-ear AKGs
2018-11-03T12:38:54 < antto> they're great
2018-11-03T12:39:02 < PeterM> i use etymotic research er-4s
2018-11-03T12:39:07 < PeterM> they are also great
2018-11-03T12:39:10 < cjbaird> I'm always surprised the wholly-plastic things haven't bust yet..
2018-11-03T12:40:00 < antto> note: i'm not picky as most "audio engineers" about sound
2018-11-03T12:40:19 < antto> i'm in a noisy room, with a HIFI (not even monitors)
2018-11-03T12:40:43 < antto> so maybe check reviews if you want studio headphones
2018-11-03T12:41:02 < PeterM> the sony mrd line is pretty standard
2018-11-03T12:41:05 < antto> but the superlux were recommended to me by a collegue
2018-11-03T12:41:50 < antto> neither do i
2018-11-03T12:42:26 < antto> it's just a hobby, and i don't work with accoustic instruments, so "meh"
2018-11-03T12:43:15 < antto> bought them for 30 euros, so i say they're okay.. had to remove those "cushions" cuz they hurt
2018-11-03T12:57:57 < malinus> I never really used one pulse mode before. Looking at the HAL HAL_TIM_OnePulse_ConfigChannel(), it seems that OPM is mostly thought to be used as a pulse in response to external interrupt. I can't really figure out how to trigger it with software.
2018-11-03T12:59:32 < malinus> Or to rephrase: I want to use the mode to generate a pulse based on a state change in software, instead of external trigger. But I can't really figure out how to trigger it without setting it up with an external trigger.
2018-11-03T13:02:33 < malinus> I guess it's a bit of a niche need, but it seems neat if I could just generate a x lenght pulse, without using interrupts+flags.
2018-11-03T13:03:13 < zyp> I tried on a pair of QC35 or something this summer, seemed pretty nice
2018-11-03T13:03:28 < zyp> almost bought it, but I couldn't justify the cost
2018-11-03T13:03:50 < Steffanx> hehe
2018-11-03T13:04:23 < jpa-> same experience
2018-11-03T13:04:38 < Steffanx> Better get it now. Then go for kids and you'll already have the head phones with noise cancelling. once you have kids you can no longer justify it :P
2018-11-03T13:04:51 < Steffanx> (or wont be allowed to)
2018-11-03T13:04:52 < zyp> I already have headphones with noise cancelling
2018-11-03T13:04:56 < Steffanx> ah ok
2018-11-03T13:05:00 < jpa-> though i tried QC35 in two stores, one of them had background noise that worked much better vs. the other
2018-11-03T13:05:10 < zyp> I bought sennheiser mm550 seven years ago or so
2018-11-03T13:05:20 < zyp> they're still going strong although the pads are falling apart
2018-11-03T13:05:24 < jpa-> protip: noise cancelling doesn't work particularly well with kids noises; earplugs + loud music does
2018-11-03T13:05:31 < PeterM> the MDR750s are a lot mroe affordable than the 100s, they are very good for the money
2018-11-03T13:05:34 < zyp> the bose got better noise cancelling though
2018-11-03T13:05:37 < PeterM> *1000s
2018-11-03T13:05:43 < BrainDamage> I have noise cancelling, it mostly works with stationary noise
2018-11-03T13:05:56 < BrainDamage> anything impulsive gets straight through
2018-11-03T13:05:57 < malinus> zyp: I never got the point of noise cancelling headphones. They are way to slow to addapt to noises that are annoying. The noise that they can cancel is cancelsed by my brain in 1min anyway
2018-11-03T13:06:02 < zyp> IMO noise cancelling is mostly a point when you're flying
2018-11-03T13:06:17 < BrainDamage> it's good inside vehicles
2018-11-03T13:06:20 < Steffanx> but isnt MDR1000 dead? And replaced by the MH-1000XM[something]?
2018-11-03T13:06:28 < malinus> yeah, so useless, because your brain calces out those kind of noises in a few minutes anyway
2018-11-03T13:06:28 < zyp> when you're on a ten hour flight it's nice to not have that constant background hum
2018-11-03T13:06:42 < PeterM> yeah but NOS is cheap and readioly available compared
2018-11-03T13:07:03 < malinus> Cracki: yeah ref manual doesn't even imply the possibility of triggering it manually
2018-11-03T13:08:18 < antto> 350 bucks for "noise canceling" sh*t? no, thankz
2018-11-03T13:08:32 < PeterM> check the mdr750s
2018-11-03T13:08:42 < malinus> Cracki: trasnfer of knowledge?
2018-11-03T13:08:50 < BrainDamage> I can't stand anything that's not in-ear
2018-11-03T13:09:05 < PeterM> i use over the ear at home and iems when out and about
2018-11-03T13:09:06 < BrainDamage> my ears feel like they have been steamed after a couple of hours
2018-11-03T13:09:23 < antto> BrainDamage take a 10 minute break then
2018-11-03T13:09:29 < zyp> I hate stuff that's on-ear, I prefer stuff that goes around the ears
2018-11-03T13:09:55 < zyp> got some headset for skype at work that's on-ear, it gets pretty uncomfortable
2018-11-03T13:10:37 < BrainDamage> antto: unfortunately, the sensation remains for a long time
2018-11-03T13:10:42 < antto> but good sound characteristics i guess are much harder on in-ear phones
2018-11-03T13:10:47 < PeterM> yeah anything that squeezxes your ears to any degree gets uncomfortable pretty quickly
2018-11-03T13:11:02 < PeterM> chopper?
2018-11-03T13:11:25 < malinus> Cracki:  https://www.st.com/content/ccc/resource/technical/document/reference_manual/3d/6d/5a/66/b4/99/40/d4/DM00031020.pdf/files/DM00031020.pdf/jcr:content/translations/en.DM00031020.pdf page 551+
2018-11-03T13:11:59 < PeterM> i thought over the ears are meant to rest onyour  head and cup your ears like your missus cups your balls
2018-11-03T13:23:25 < malinus> Cracki: huh, it seems that if I just enable the OPM bit, the pwm output just keeps being high.
2018-11-03T13:25:31 < malinus> yeah I have the pwm running with the duty cycle I want. I figured I could just set the OPM bit, and start it, for a "one pulse"?
2018-11-03T13:30:17 < malinus> Cracki: setting the OPM, just results in the output being stuck high
2018-11-03T13:30:25 < malinus> Cracki: at least wile running PWM mode

2018-11-03T14:59:24 < jpa-> rainy
2018-11-03T14:59:37 < jpa-> i'm finally upgrading to ubuntu 18.04
2018-11-03T14:59:55 < jpa-> it's removing all the stuff i use and installing some weird stuff instead
2018-11-03T15:00:18 < con3> eh startup script is broken but I didn't touch it
2018-11-03T15:02:12 < catphish> BrainDamage: the ring of reflected lights are from LEDs mounted on the camera
2018-11-03T15:02:29 < BrainDamage> maybe add a diffuser?
2018-11-03T15:02:58 < jpa-> building a good ring light is surprisingly difficult
2018-11-03T15:03:24 < jpa-> mine looks like a bunch of dots also, though it is 30 leds or something and a crappy diffuser
2018-11-03T15:03:32 < catphish> yeah someoene recommended making a simple diffuser with with about any translucent material

2018-11-03T15:03:59 < catphish> there's way more light than i need, so might get away with using paper or similar
2018-11-03T15:04:15 < jpa-> you could also use a polarizer to block out the reflections
2018-11-03T15:15:22 < bitmask> well some of these batteries must be fakes, that sucks
2018-11-03T15:15:51 < bitmask> these "LG" "3000 mAh" are getting like 1800
2018-11-03T15:17:57 < PeterM> whered you get em? im guessing not lg?
2018-11-03T15:18:11 < bitmask> dont remember, had them for a few years
2018-11-03T15:18:38 < bitmask> I have 7 others that are supposed to be sony brand, not sure if those are legit either
2018-11-03T15:19:03 < bitmask> they all get between 75 and 85 mohm IR though so they should at least work fine
2018-11-03T15:23:07 < bitmask> I might have to buy 3 more batteries to make a 4th pack, gonna need another 3S battery holder and protection board too though.  I guess I'll see how long these 3 packs actually last
2018-11-03T15:23:14 < catphish> i'm having a bit of a fight with my motion controller right now
2018-11-03T15:23:37 < catphish> specifically that it doesn't seem to always move at all when jogged by 0.1mm which makes me think there's some serious accuracy problems :(
2018-11-03T15:24:09 < bitmask> thats weird, I hate problems that 'sometimes' occur
2018-11-03T15:24:27 < bitmask> either fuck up or dont, so much easier to fix :P
2018-11-03T15:25:06 < catphish> it's like somtimes it decides 0.1mm isn't enough to justify moving the motor at all
2018-11-03T15:25:18 < catphish> but my resolution is 64 steps per mm
2018-11-03T15:25:50 < bitmask> what about rounding errors in the software?
2018-11-03T15:26:09 < catphish> so each 0.1mm should always be either 6 or 7 steps
2018-11-03T15:26:15 < jpa-> catphish: is it 64 real steps or 64 microsteps per mm?
2018-11-03T15:26:21 < catphish> jpa-: microsteps
2018-11-03T15:26:27 < jpa-> how much x microstepping?
2018-11-03T15:26:33 < bitmask> 16?
2018-11-03T15:26:56 < catphish> either 32 or 16
2018-11-03T15:27:18 < catphish> (with 64 or 32 steps per mm respectively) both exhibit the same behavious
2018-11-03T15:27:20 < jpa-> it could be that the motor is a bit sticky and 1/5th of a one full step isn't enough torque to start it moving
2018-11-03T15:27:21 < catphish> *behaviour
2018-11-03T15:27:52 < catphish> hmm
2018-11-03T15:28:33 < catphish> i don't think it's that, same thing happens if i apply constant torque myself at the same time
2018-11-03T15:28:54 < jpa-> you could put a scope on the pulse input to the stepper driver chip to see if the controller commands movement or not
2018-11-03T15:29:10 < catphish> that's a good idea
2018-11-03T15:29:27 < catphish> i know very very little about stepper controllers
2018-11-03T15:29:43 < catphish> but i am in posession of a very nice scope :)
2018-11-03T15:30:49 < catphish> not totally sure what i;m looking for
2018-11-03T15:31:00 < bitmask> stepper drivers are very simple
2018-11-03T15:31:21 < bitmask> find the step pin and to make it move you just raise and then lower it
2018-11-03T15:31:31 < bitmask> so make sure its getting the pulses
2018-11-03T15:33:25 < bitmask> is your acceleration or jerk value too high? if you start at too fast a rate it wont work, but you can start slower and accelerate to faster rates

2018-11-03T15:33:49 < bitmask> I'm doubting thats the problem though
2018-11-03T15:34:00 < jpa-> yeah, you should see a square wave on the step pin, you can even count how many steps your motion controller is commanding to the stepper chip
2018-11-03T15:34:36 < catphish> this is where i regret using a poorly documented chinese board
2018-11-03T15:34:47 < bitmask> what driver is it?
2018-11-03T15:35:05 < BrainDamage_> if your microsteps are too small compared to the electrical constants, you might not be integrating sufficient current to get enough torque to win the static friction
2018-11-03T15:35:13 < catphish> got it
2018-11-03T15:35:33 < bitmask> still curious though, what drivers are you using?
2018-11-03T15:35:55 < bitmask> must not be a4988 if you can use 1/32
2018-11-03T15:36:18 < bitmask> you probably use higher current anyway, are they 8825?
2018-11-03T15:37:03 < catphish> DRV8825

2018-11-03T15:39:52 < bitmask> they only help drv8825, just a bunch of diodes that help create a better square wave
2018-11-03T15:40:29 < bitmask> or sine wave, I forget what :P
2018-11-03T15:41:24 < bitmask> I think drv8825 are just noisey (signal) and therefore create noise (acoustic) and some jitter
2018-11-03T15:41:48 < catphish> these pulses are insanely short, hard to see several on a scope
2018-11-03T15:43:01 < jpa-> fancy scope should help ;)
2018-11-03T15:43:02 < catphish> they're just under 4uS
2018-11-03T15:43:50 < catphish> gt2 50T
2018-11-03T15:44:14 < bitmask> 50T is the number of teeth
2018-11-03T15:44:23 < catphish> i didn't know that, but yes 2mm
2018-11-03T15:44:35 < catphish> and yes, 50 teeth on the steppers
2018-11-03T15:44:38 < bitmask> curious, why did you go with 50t?
2018-11-03T15:45:01 < catphish> recommendation, i suspect it's a mistake
2018-11-03T15:45:31 < bitmask> well the accuracy is probably fine for a pnp
2018-11-03T15:45:34 < catphish> and yes at 1/32 microstepping, 64 steps per mm
2018-11-03T15:45:51 < jpa-> steppers always have a tradeoff between accuracy and maximum speed
2018-11-03T15:46:15 < catphish> i'd say there wasn't any slack
2018-11-03T15:46:16 < bitmask> you using fiberglass belts or steel core?
2018-11-03T15:46:44 < bitmask> with 50T you can probably use steel
2018-11-03T15:47:01 < catphish> when i'm accusing it of not moving, it actually is, just by a much much smaller amount
2018-11-03T15:47:15 < bitmask> oh, thats very different
2018-11-03T15:47:15 < catphish> i'm gonna count the pulses now, but i'm struggling to work out how to do so with this scope

2018-11-03T15:48:37 < jpa-> which scope?
2018-11-03T15:48:44 < catphish> its a HMO1024
2018-11-03T15:48:48 < bitmask> or the pulses are too quick

2018-11-03T16:32:32 < jpa-> to have an inaccuracy on the order of about 1/2 of a full step
2018-11-03T16:34:17 < jpa-> https://www.geckodrive.com/support/step-motor-basics.html   though it depends on how much torque you demand of it

2018-11-03T16:57:33 < catphish> most likely the former
2018-11-03T16:57:57 < catphish> it's a chinese copy of a smoothieboard, probably running at lower frequency
2018-11-03T16:59:16 < bitmask> only 1A? that could definitely be why
2018-11-03T16:59:26 < bitmask> what size steppers, they are nema2x something right?

2018-11-03T19:55:52 < catphish> Cracki: i'm actually glad you spotted that, because that's one component that ended up particularly badly aligned, but looks like its purely wrong data
2018-11-03T19:56:42 < catphish> yes, it can use fiducials, the angle of the board is unimportant, i just have the board straight so that if there's a problem i can see which axis is bad
2018-11-03T19:57:15 < catphish> even without fiducials you can tell it the center of any 2 components and it offsets and rotates everything accordingly
2018-11-03T19:58:34 < catphish> afaik it can only use a lone circle as a fiducial, it can't detect the location of a capacitor for example
2018-11-03T19:58:56 < catphish> you can tell it "this is the center of component C1"

2018-11-03T20:00:35 < catphish> it has an incredible ability to focus almost infinitely close

2018-11-03T20:02:29 < PaulFertser> catphish: noted, thanks!
2018-11-03T20:03:39 < PaulFertser> catphish: do you think that'll be enough for 0201?
2018-11-03T20:08:21 < catphish> PaulFertser: i wouldn't like to guess, 0201 is *hard*, i'd definitely go down to a smaller drive pulley
2018-11-03T20:08:46 < catphish> my demo is 0603 and it looks pretty comfortable, probably 0402 would be ok, but i will never try 0201 myself

2018-11-03T23:50:27 < catphish> i'm still very confused about why sometimes 3 microsteps moves the motor and sometimes it doesn't

2018-11-03T23:54:49 < catphish> i don't know much about configuring it, but certainly my results show non-linearity in the microstepping region
2018-11-03T23:57:54 < catphish> it's not clear to me what is configurable

2018-11-03T23:59:29 < catphish> right now i have 0.5mm per full step, i wonder if i'd be better changing the mechanical setup
--- Day changed Sun Nov 04 2018
2018-11-04T00:02:30 < catphish> i don't believe it's a great chip
2018-11-04T00:03:13 < catphish> if i swap out my 50 tooth pulley for 16 tooth, i'm going to instantly win 3x the accuracy at the cost of 3x the max speed, and i'm nowhere near maxing out on speed
2018-11-04T00:03:23 < catphish> or i could spend more on drivers, or both
2018-11-04T00:05:08 < catphish> i wonder what the smoothieboard has on board, that's the board openpnp recommends, but i cheaped out and got a chinese clone with the cheapest possible parts on it
2018-11-04T00:06:28 < catphish> well it can't achieve 16 with any accuracy
2018-11-04T00:08:44 < catphish> i don't see why this couldn't be done better with an stm32 and a bunch of mosfets
2018-11-04T00:09:17 < catphish> oh, i guess current monitoring is the hard part
2018-11-04T00:10:31 < aandrew> current monitoring isn't terribly hard
2018-11-04T00:10:35 < catphish> smoothieboard has A5984 drivers

2018-11-04T00:10:47 < aandrew> depending on what your'e after
2018-11-04T00:11:02 < catphish> makes sense
2018-11-04T00:11:26 < catphish> honestly, i think i'd prefer to avoid reliance on microstepping and adjust my mechanical setup
2018-11-04T00:13:12 < catphish> 24V
2018-11-04T00:13:49 < catphish> that might explain why it was more consistent when i upped the current
2018-11-04T00:14:08 < catphish> because i'm using high voltage and low current, the drive time will be minimal
2018-11-04T00:15:03 < catphish> ironically i spec'd everything for high voltage because i thought the steppers would run better
2018-11-04T00:16:11 < catphish> well on the full step, it has to turn the second coil off surely
2018-11-04T00:16:52 < catphish> my steppers are 2 ohms (spec) 2.6ohm (measured)
2018-11-04T00:17:27 < catphish> this means they only need 2 volts to achieve my target current of 1A
2018-11-04T00:18:41 < catphish> that's going to seriously limit the microstepping resolution :(
2018-11-04T00:19:02 < catphish> interestingly, one of my axes has 2 motors in series, it's much more accurate
2018-11-04T00:19:53 < catphish> i have them because they're cheap
2018-11-04T00:20:19 < catphish> annoyingly i have a ton of 24v hardware
2018-11-04T00:22:28 < catphish> seems like i have at least 2 ways to attack this :)
2018-11-04T00:24:18 < catphish> i can also consider 0.9 degree rather than 1.8 degree steppers

2018-11-04T00:25:58 < catphish> about 40% more expensive

2018-11-04T00:27:08 < catphish> starting to better understand the problem at least
2018-11-04T00:34:15 < catphish> seems i have 4 options 1) use less input voltage 2) change the steppers to 0.9 degrees 3) change my pulleys from 50 to 16 teeth 4) buy better drivers

2018-11-04T00:47:02 < catphish> i know you already said this... but this is ridiculous, the blanking time of 3.75uS is 10% of the PWM frequency, that means the minimum PWM duty cycle is 10%, but at 2.6 ohms and 24v, the maximum duty cycle i need is 11%
2018-11-04T00:47:14 < catphish> how am i getting *any* microstepping here?
2018-11-04T00:48:10 < catphish> that's true
2018-11-04T00:48:21 < catphish> stupid inductors
2018-11-04T00:48:55 < catphish> yeah i guess the inductance is buying me some time
2018-11-04T00:50:18 < catphish> but still, the duty cycle should be around 10% shouldn't it?
2018-11-04T00:51:45 < catphish> relly? i thought ultimately that's what would determine it
2018-11-04T00:52:01 < catphish> i thought the inductance would just smooth it
2018-11-04T00:52:03 < zyp> sup?
2018-11-04T00:52:07 < zyp> having problems stepping?
2018-11-04T00:52:13 < catphish> zyp: yep
2018-11-04T00:52:27 < zyp> what's the matter?
2018-11-04T00:52:43 < catphish> zyp: basically my microsteps are not linear
2018-11-04T00:52:54 < catphish> zyp: some of the microsteps move the shaft, some don't
2018-11-04T00:53:57 < catphish> zyp: essentially i get something lke this: https://hackadaycom.files.wordpress.com/2016/08/drv8825.jpg
2018-11-04T00:54:28 < zyp> why are you using 50 tooth pulleys?
2018-11-04T00:54:48 < catphish> zyp: i just am, it was recommended
2018-11-04T00:55:01 < catphish> so that's what i have :)
2018-11-04T00:55:35 < catphish> but regardless of that, i'm dissatisfied that my 1/16 microstepping does not move the shaft 1/16th of a step with each microstep
2018-11-04T00:55:51 < catphish> yes https://ooznest.co.uk/wp-content/uploads/2018/07/NEMA17-Stepper-Motors-Drawing.jpg
2018-11-04T00:56:01 < catphish> 3.3mH
2018-11-04T00:56:59 < catphish> but... my understanding of inductance is that regardless of the inductance, the current is going to end up being the voltage divided by the ohmic resistance times he duty cycle
2018-11-04T00:58:09 < zyp> sounds like you just need better stepper drivers
2018-11-04T00:58:52 < catphish> zyp: that's essentially the conclusion i've come to
2018-11-04T00:59:52 < catphish> i was of the belief that if you have 10% duty cycle at 24 volts, you will get the same average current as 100% at 2.4v
2018-11-04T01:00:33 < catphish> as long as the saw tooth is never clipped
2018-11-04T01:04:42 < catphish> that could be what's happening here, yes
2018-11-04T01:05:34 < catphish> zyp: the steppers have a minimum duty cycle of 10% (as far as i can tell from the datasheet) which definitely explains the horrible behaviour
2018-11-04T01:05:45 < catphish> *stepper drivers
2018-11-04T01:06:22 < catphish> and because i'm driving the motors to 1A at 24v and they have resistance of 2.6R, i'm amazed i get any resolution at all
2018-11-04T01:06:41 < catphish> since the max and min duty cycle are both in theory 10%
2018-11-04T01:07:14 < catphish> the 2A rated one
2018-11-04T01:08:04 < catphish> but i really suspect i just need better drivers here
2018-11-04T01:11:48 < catphish> someone commented "The 8825 is well-known to skip microsteps with low-inductance motors in mixed decay mode. Causes all sorts of ripples and crunching noises in 3D printers. You need to switch it to fast decay mode if you want proper microstep spacing."
2018-11-04T01:12:00 < catphish> "The problem is that the PWM chopper’s minimum on-time (blanking time) is way too long, which allows the coil current to rise way higher than it’s supposed to on certain microsteps. You can plug the motor specs into my stepper driver simulator to see for yourself what the coil currents are doing: https://github.com/rcarlyle/StepperSim"
2018-11-04T01:13:18 < catphish> i wonder actually what current you get with 24v, 3.3mH, and 4uS
2018-11-04T01:16:03 < catphish> at 3.3mH, 4uS comes nowhere close to being a problem
2018-11-04T01:17:27 < catphish> in fact according to my calculation, 7 amps per millisecond, only 7mA per mucrosecond
2018-11-04T01:18:15 < catphish> so IMO it'll be perfectly able to regulate the current
2018-11-04T01:18:52 < catphish> i'll try :)

2018-11-04T01:41:57 < catphish> the diode hack needs a LOT of diodes :(
2018-11-04T01:42:35 < PeterM> i thought the general thing was up the voltage and add series resistance
2018-11-04T01:42:50 < PeterM> that way the inductance plays a smaller role in the current 
2018-11-04T01:43:25 < PeterM> i guess the diodes do the same thing
2018-11-04T01:43:28 < PeterM> sortof
2018-11-04T01:44:20 < catphish> yeah, i'm a little confused really, in this writeup he concudes that he can't use resistors because of the power that would need to be dissipated
2018-11-04T01:44:31 < catphish> then proceeds to use diodes
2018-11-04T01:44:41 < PeterM> yeah that doesnt make sense
2018-11-04T01:45:02 < catphish> which must have to dissipate the same heat, but have the advantage of dropping more voltage at lower current
2018-11-04T01:45:24 < catphish> so, i don't know
2018-11-04T01:45:51 < PeterM> you dont care about dropping voltage, jsut limiting maximum current
2018-11-04T01:46:49 < PeterM> yeah, you crank up the voltage, and add resitance, so the resistance is the dominant part of the current limiting, not hte inductance
2018-11-04T01:47:22 < PeterM> and so you get a more linear response
2018-11-04T01:47:38 < catphish> essemtially his explanation is that if you can block 1.4v, the drivers can drive lower currents correctly
2018-11-04T01:49:58 < PeterM> how do they help with decay any mroe than reducing the  supply by 1.4v
2018-11-04T01:50:54 < PeterM> but the coil acts as a current source, not a votlage source
2018-11-04T01:51:32 < PeterM> yeah, but then why diodes not resistors?
2018-11-04T01:51:50 < catphish> so, he claims the driver is unable to produce low currents, i assume because of its minimum duty cycle
2018-11-04T01:52:14 < catphish> would adding voltage to thr coil fix that?
2018-11-04T01:52:42 < catphish> sorry, no, i mean voltage drop, with the diodes
2018-11-04T01:55:15 < catphish> actually i don't understand how diodes will help any more than resistors at all
2018-11-04T01:55:32 < catphish> they do nothing that reducing the power supply by 1.4v doesn't do
2018-11-04T01:56:01 < catphish> and yet, i'm looking at evidence that dramatically improve things
2018-11-04T01:56:25 < catphish> 2, for a 1.4v drop
2018-11-04T01:56:53 < catphish> there are 8 per motor
2018-11-04T01:57:11 < catphish> 2 per polarity per coil
2018-11-04T01:57:54 < catphish> the thing i don't get is that the problem is time vs inductance related, and diodes don't change that
2018-11-04T01:58:57 < catphish> oh ffs
2018-11-04T01:59:31 < catphish> does he say what voltage he runs it at ultimately?
2018-11-04T02:00:31 < catphish> "But we found out what is the problem, in mixed decay mode, the driver cannot do any voltage lower than 12% of the supply voltage. So the small currents needed for the microstepping will not be possible."
2018-11-04T02:00:38 < catphish> he agrees about the problem at least
2018-11-04T02:03:46 < catphish> the problem is, imo the diodes just move the dead zone
2018-11-04T02:04:00 < catphish> because the 24v will instantly overcome the diodes
2018-11-04T02:04:18 < catphish> that's exactly my thingink
2018-11-04T02:04:33 < catphish> imo he's just done the resistor solution he previously dismissed
2018-11-04T02:04:39 < catphish> but using less resistance
2018-11-04T02:05:49 < catphish> how about adding more inductors?
2018-11-04T02:06:09 < catphish> series dammit
2018-11-04T02:07:11 < catphish> my coincidental observation that it's better with 2 motors basically proves that resistors and/or inductors and/or less supply voltage will solve this
2018-11-04T02:07:15 < catphish> but it's a shit situation
2018-11-04T02:08:05 < catphish> indeed
2018-11-04T02:08:52 < catphish> both the inductance and resistance help here
2018-11-04T02:09:01 < catphish> the ultimate duty cycle is doubled
2018-11-04T02:09:12 < catphish> and the change in current over time is halved
2018-11-04T02:09:42 < catphish> again, they're in series
2018-11-04T02:10:03 < catphish> driving them in parallel would be suicidal
2018-11-04T02:10:46 < catphish> you'd gen potentially unequal current, less control, twice the current through the driver for zero gain
2018-11-04T02:10:52 < catphish> *get
2018-11-04T02:11:57 < catphish> putting them in series means setting the driver to 1A means both motors get exactly 1A
2018-11-04T02:12:00 < catphish> which is ideal
2018-11-04T02:12:23 < catphish> and twice the duty cycle means more accurate control
2018-11-04T02:12:55 < catphish> a 3.3 ohm resistor might fix this problem :)
2018-11-04T02:14:10 < catphish> it would dissipate 3.3W at 1A, and would dramatically increase the required duty cycle, but then running the system at 12V would have the same effect
2018-11-04T02:16:01 < catphish> but then, maybe just buying drivers that aren't shit would also help

2018-11-04T03:03:55 < jadew> out of 3 edge mount connectors, 3 of them make imperfect contact

2018-11-04T03:08:49 < jadew> I actually went for these particular ones because I knew they're a bit loose (mounting wise)
2018-11-04T03:09:14 < jadew> didn't realize they suck all around till now

2018-11-04T11:50:39 < dongs> typical UI: << < 1 to 50 of 576 > >>
2018-11-04T11:50:42 < dongs> come on germans
2018-11-04T11:50:46 < dongs> nobody needs this much detail about anythign
2018-11-04T11:51:03 < Steffanx> Wtf is it
2018-11-04T11:51:44 < dongs> it draws shitty graphs of network usage, something mikrotik fails to do properly
2018-11-04T12:12:10 < Steffanx> So does the dongs use HAL/cube or just the ll_* stuff part of the cube?
2018-11-04T12:12:17 < dongs> neither
2018-11-04T12:12:32 < Steffanx> Bare registers?
2018-11-04T12:12:33 < dongs> i just use chips that have stdperiphl
2018-11-04T12:12:36 < Steffanx> Haha
2018-11-04T12:12:54 < dongs> i backported touchsense from hal to stdperiph-like way for F0 and F3
2018-11-04T12:13:01 < Steffanx> ll_* is pretty close to std.
2018-11-04T12:13:04 < dongs> which is the only peripheral i was missing
2018-11-04T12:13:08 < dongs> nah, the syntax is fucking atrocious
2018-11-04T12:13:13 < dongs> ive tried it, jsut looks gross
2018-11-04T12:13:41 < Steffanx> Hm
2018-11-04T12:13:54 < dongs> anyway, if I had no choice, probly LL
2018-11-04T12:13:57 < dongs> hal is out
2018-11-04T12:55:30 < Sadale> it isn't.

2018-11-04T13:05:16 < Sadale> If I'm to be honest, I'd say each microcontroller has its pros and cons. There's no the best one.
2018-11-04T13:05:23 < Sadale> Just pick the one that suits your need.
2018-11-04T13:05:43 < antto> but if you have to be on ##stm32 you shall not be honest
2018-11-04T13:05:51 < Sadale> ow
2018-11-04T13:16:02 < Sadale> I've made my first PCB in my life. :3
2018-11-04T13:16:25 < Sadale> I've sent the gerber files to a fab. Let's hope that my design isn't wrong.
2018-11-04T13:16:41 < antto> <hope.gif>
2018-11-04T13:18:08 < Sadale> I sent it to someone marketing their service on taobao.
2018-11-04T13:18:30 < Sadale> Wow wait. $2 per 10 PCBs? :O
2018-11-04T13:18:31 < Sadale> I did.
2018-11-04T13:18:37 < antto> Sadale those are trap questions, don't answer!
2018-11-04T13:18:56 < Sadale> antto, what's wrong with using kicad as a hobbyist?
2018-11-04T13:19:08 < Sadale> crap
2018-11-04T13:19:14 < Sadale> antto, I should have used lcpcb.
2018-11-04T13:19:17 < Sadale> jlcpcb*
2018-11-04T13:20:48 < Sadale> I paid like $10 for 10 boards, shipping fee included :c
2018-11-04T13:20:49 < antto> how? o_O
2018-11-04T13:20:54 < Sadale> Now I'm feeling dumb.
2018-11-04T13:21:37 < Sadale> wait
2018-11-04T13:21:42 < Sadale> Does jlcpcb ship to China?
2018-11-04T13:21:54 < antto> hahaa
2018-11-04T13:21:58 < Sadale> There's no "China" nor "People's Republic of China" in the shipping estimation selector
2018-11-04T13:22:03 < Sadale> Yes. It's from China.
2018-11-04T13:22:47 < antto> smells like he's in china
2018-11-04T13:22:48 < Sadale> Hong Kong.
2018-11-04T13:23:12 < Sadale> But I use a warehouse service in China. So I often ask those mainland China retailers to send stuffs to the warehouse.
2018-11-04T13:23:20 < Sadale> Then I ask the warehouse to send it to Hong Kong.
2018-11-04T13:24:11 < Sadale> I'm thinking if someone could abuse the prototyping service.
2018-11-04T13:24:23 < Sadale> y'know, prototyping is cheap. But small scale production isn't.
2018-11-04T13:24:52 < Sadale> If you ask like 10 PCB fabs to produce 10 PCB for you, you could get 100 boards at a cheap price.
2018-11-04T13:25:23 < Steffanx> The effort to do that all costs money as well :P
2018-11-04T13:25:29 < antto> wut bout shipping and difference in the boards?
2018-11-04T13:25:58 < antto> i doubt they gonna look like they all came from the same batch
2018-11-04T13:26:10 < antto> but maybe you don't care bout that
2018-11-04T13:26:27 < Sadale> true :P
2018-11-04T13:26:49 < Sadale> What's happen if it doesn't look like that it's coming from the same batch?
2018-11-04T13:27:07 < Sadale> anyway, the effort does cost money xD
2018-11-04T13:27:29 < Steffanx> Are you happy with the new bridge that finally opened Sadale
2018-11-04T13:27:38 < Sadale> Oh. Of course :3
2018-11-04T13:27:46 < Sadale> It makes traveling to Macau faster.
2018-11-04T13:28:12 < Steffanx> Something youll do once/decade? ;)
2018-11-04T13:29:04 < Sadale> I guess I'll probably visit there once or twice in later point of my life :P
2018-11-04T13:31:09 < Sadale> Macau.
2018-11-04T13:31:22 < Sadale> Mainly because it's close to Hong Kong :p
2018-11-04T13:33:12 < Steffanx> Are you a born and raised hong konger Sadale?
2018-11-04T13:33:19 < Sadale> I am. :3

2018-11-04T13:36:10 < Steffanx> sky, superbia
2018-11-04T13:36:13 < Sadale> I had it. I resigned :P
2018-11-04T13:36:28 < Sadale> In fact the job wasn't nice at all. The compensation was subpar and the work hours was bullshit.
2018-11-04T13:37:04 < Steffanx> You can always get some huge implants and make youtube vidoes. :P
2018-11-04T13:37:07 < PaulFertser> Steffanx: do you mean you offer Sadale do somehow relocate to EU?
2018-11-04T13:37:38 < PaulFertser> Or to mainland China?
2018-11-04T13:37:45 < Sadale> ...
2018-11-04T13:37:49 < Sadale> I'm a boy.
2018-11-04T13:37:50 < Steffanx> I didnt offer anything, i think, PaulFertser?
2018-11-04T13:38:24 < Sadale> I doubt anyone would watch my youtube vid after getting implants xD
2018-11-04T13:38:29 < PaulFertser> Steffanx: well, yes, sorry
2018-11-04T13:39:07 < Steffanx> isnt that kinda the china way Sadale? the compensation + huge work load?
2018-11-04T13:39:17 < Steffanx> Not sure if that applies to hk as well. i know little about hk
2018-11-04T13:39:28 < Sadale> yep. That's why I don't like the culture here.
2018-11-04T13:39:49 < PaulFertser> Steffanx: I manage to misread shenzhen as Schengen :)
2018-11-04T13:39:53 < Sadale> I think this applies to most cities in Sino cultural sphere.
2018-11-04T13:39:57 < Steffanx> haha PaulFertser:D
2018-11-04T13:40:06 < Sadale> lol
2018-11-04T13:40:23 < Sadale> close enough. :P
2018-11-04T13:40:43 < Sadale> Japan's work culture is even worse.
2018-11-04T13:40:45 < PaulFertser> Sadale: would you be able to understand to mainland china people reasonably well?
2018-11-04T13:40:51 < Sadale> Hong Kong is a bit better than Japan I guess.
2018-11-04T13:41:03 < Sadale> PaulFertser, not really. Depending on their accent and rate of speech.

2018-11-04T13:47:10 < cjbaird> 16-core coax scares me. But if I can find it shielded, might be an option for the ubitx flywire issue..
2018-11-04T13:51:18 < cjbaird> ...might be an option if it were available in orders less than a kilometre.
2018-11-04T13:51:55 < BrainDamage> you can always get another ribbon, but get one with twice the leads, and interleave ground with signals
2018-11-04T13:52:08 < BrainDamage> it'll greatly reduce interference

2018-11-04T13:56:53 < PaulFertser> I wonder if Sadale can enroll in some cool free German uni.
2018-11-04T13:57:44 < Steffanx> people can do that for free?
2018-11-04T13:58:17 < PaulFertser> I think yes, Germany provides free education for all IIRC.
2018-11-04T13:59:12 < cjbaird> Hm. IDC-34/floppy cables.. Top row gives 17 wires (need only 16), and the bottom row can be grounded+terminated.. and it's easy-enough to make up ~8cm lengths.

2018-11-04T14:46:04 < Steffanx> oh i misinterpreteed
2018-11-04T14:47:15 < jpa-> catphish: so basically you changed the decay mode of the driver?
2018-11-04T14:47:21 < catphish> Steffanx: it's a combination of problems, but the solution many people propose is to use this driver IC in a different mode (fast decay), some solder bridges achieve this
2018-11-04T14:47:26 < catphish> jpa-: yes
2018-11-04T14:47:51 < catphish> jpa-: but in a god awful way by bridging the enable pin to the decay mode pin and also the error output pin
2018-11-04T14:47:58 < jpa-> stepper decay modes have always confused me
2018-11-04T14:48:14 < catphish> i don't fully understand it, it's abut how it's connected when not driven i believe

2018-11-04T14:49:28 < catphish> it's also now extremely loud
2018-11-04T14:49:38 < jpa-> yeah, in 3-phase motor driving there is something similar, you can either leave the coil disconnected (discharging through diodes), short-circuit connected or connected to opposite polarity voltage
2018-11-04T14:49:57 < jpa-> and this affects how fast the current through the coil will change
2018-11-04T14:50:04 < jpa-> but then why and when to pick which mode

2018-11-04T15:25:55 < Steffanx> the idea behind growing weed is that you dont pay the electricity bill yourself...
2018-11-04T15:26:20 < Laurenceb124> according to uni guys who were working on this and failing, nobody makes anything cost effective thats passively cooled
2018-11-04T15:26:25 < Laurenceb124> that was my business idea
2018-11-04T15:26:55 < Laurenceb124> but there is v little real world data on LED lifetime
2018-11-04T15:27:17 < Laurenceb124> for recent power LEDs, its kind of impossible to knowe

2018-11-04T16:56:06 < Sadale> I can't speak English well either :3
2018-11-04T16:56:40 < Sadale> Anyway I think my English is probably good enough for communication with non-native English speakers. Those people speak slower than the natives.
2018-11-04T16:56:42 < PaulFertser> Sadale: they have plenty of English-only classes. I guess your level is perfectly adequate.

2018-11-04T17:03:20 < Sadale> I guess my written one is fine, tho. I have been chatting on freenode for years in English :3
2018-11-04T17:03:35 < Steffanx> isnt english one of the languages spoken in hk?
2018-11-04T17:04:05 < Sadale> technically English is one of the legal languages in Hong Kong.
2018-11-04T17:04:20 < Sadale> In fact all of us just speak Cantonese for communication among locals.
2018-11-04T17:04:36 < Sadale> We do use English, only for talking with tourists or other foreigners.
2018-11-04T17:04:42 < Steffanx> hm
2018-11-04T17:05:05 < Sadale> There're some occasions here we'd speak English. But we're speaking retardedly slow.
2018-11-04T17:05:43 < Sadale> I can perfectly understand the English spoken here because they speak real slow in Hong Kong. Those westerners do realize that we can't handle native speech rate of spoken English.
2018-11-04T17:06:32 < Steffanx> lol, im a "westerner" but its not my native language either ;)

2018-11-04T17:20:57 < Steffanx> capacitor.
2018-11-04T17:20:57 < catphish> yes, 0603 cap
2018-11-04T17:21:12 < Sadale> I meant that machine. Not the cap.

2018-11-04T17:21:46 < Sadale> cool! O_o
2018-11-04T17:21:56 < catphish> malinus: ya, based on openpnp and various other people's designs
2018-11-04T17:24:41 < malinus> catphish: cool. Do you do a lot of board assembly at home, or is it just a fun project?
2018-11-04T17:25:19 < catphish> mostly the latter
2018-11-04T17:25:41 < catphish> but i'd like to do more prototyping / small assembly runs at home for other projects
2018-11-04T17:26:08 < Sadale> But having a pnp makes home assembly much faster than manual assembly I guess.
2018-11-04T17:26:48 < englishman> that jury is still out
2018-11-04T17:28:35 < catphish> lol we'll see about that
2018-11-04T17:30:27 < malinus> What is the price for board assembly in china? PCB's are ~free, but I guess assembly would still cost a bit? I bet some chinese offer small runs for prototypes in back rooms and whatnot
2018-11-04T17:34:39 < jpa-> seeed says "PCBA orders start from $25 set up fee with $0.01 to $0.30 assembly fee per component."
2018-11-04T17:35:49 < malinus> that's cheap man

2018-11-04T19:55:29 < Steffanx> If you are semi-ghettoing anyway, i dont see why one of those semi cheap compressor based dispensers wont work.
2018-11-04T19:55:35 < catphish> malinus: yes, one sided only :)
2018-11-04T19:57:38 < catphish> i still have a bit of work to do to improve placement accuracy

2018-11-04T19:58:45 < catphish> indeed, this can correct small errors in the picking process

2018-11-04T20:02:22 < catphish> that's not a bad idea
2018-11-04T20:02:35 < catphish> paste is messy and right now i'm reusing the parts

2018-11-04T20:04:20 < catphish> yeah the only component i did slowly / manually retracted was perfectt
2018-11-04T20:05:02 < catphish> i guess with a dry surface, it doesn't take much to make the part bounce

2018-11-04T22:35:45 < malinus> what about unit testing?
2018-11-04T22:40:45 < malinus> yeah qemu is neat for some stuff, but you don't get any peripherals. Might as well just do unit testing on host imho.
2018-11-04T22:42:31 < malinus> yeah doing black box testing always makes sense with embedded it seems

2018-11-04T23:37:21 < antto> kid cries or makes sounds -> stick a smartphone in its hands -> parenting success

2018-11-04T23:41:44 < antto> when i was a kid, most people thought that for a kid to have a computer is a bad thing.. coz playing games all day instead of doing homework
2018-11-04T23:41:52 < antto> IMO phones now are much worse
2018-11-04T23:42:40 < Steffanx> Yeah. True (says steffanx using a irc client on his phone)
2018-11-04T23:43:01 < antto> and i'm sure most of those same people who said that then, are now rubbing their smartphones
2018-11-04T23:45:07 < Steffanx> We have this classic video where they interviewed people. They asked if they would like it to be able to call and be called all day long (referring to mobile phones).
2018-11-04T23:45:22 < Steffanx> No one liked the idea.
2018-11-04T23:45:27 < Steffanx> We = thr dutch.
2018-11-04T23:47:04 < antto> i remember the time when you had to go ring the doorbells to gather all the gang
2018-11-04T23:47:20 < Steffanx> Was in 1999. 
2018-11-04T23:47:25 < antto> yeah
2018-11-04T23:48:08 < Steffanx> Hah yes. Or yell at the backdoor.
2018-11-04T23:48:23 < Steffanx> Just the figure out your friend wasnt home
2018-11-04T23:48:44 < antto> *riiiing* *riiiiiiing* ... "who is it?" "o hai, is Ivan there?"
2018-11-04T23:48:56 < Steffanx> Crazy Ivan.
2018-11-04T23:49:28 < antto> "yes but he's NOT going out till he does his homework"

2018-11-04T23:49:42 < Steffanx> The good old times. Damn, this millenial gets old?!?
2018-11-04T23:50:59 < Steffanx> Is antto a millenial? (Born between 1980 and 2000)?
2018-11-04T23:51:16 < Steffanx> Millennial* or whatever
2018-11-04T23:51:56 < antto> i still don't understand what's this label about
2018-11-04T23:53:59 < aandrew> my kids don't get devices in order ot be quiet
2018-11-04T23:54:05 < antto> besides being a year-of-birth based discrimination
2018-11-04T23:54:07 < aandrew> they get them as a reward FOR being quiet
2018-11-04T23:54:37 < Steffanx> Not even a pacifier?
2018-11-04T23:55:49 < aandrew> it's been a long time since they've needed pacifiers
2018-11-04T23:56:05 < Steffanx> Haha
2018-11-04T23:56:08 < antto> teh internetz is teh new pacifier
2018-11-04T23:56:51 < aandrew> I honestly don't mind my kids on youtube/webshit because MOST of the time they're reading/watching something educational. they know I have zero tolerance for them watching stupid shit online
2018-11-04T23:57:19 < aandrew> so the one has watched practically every nasa documentary you can imagine and knows more about how to fly a plane than I ever will
2018-11-04T23:57:27 < aandrew> the ohter isn't doing much yet
2018-11-04T23:57:50 < aandrew> lol
2018-11-04T23:57:55 < antto> they gon analyze the trajectory of the butt cheekz

2018-11-05T00:06:12 < aandrew> it's amusing how kids think they can get around the router
2018-11-05T00:06:26 < aandrew> the 23yo (when he was 16-17) had a similar eduation

2018-11-05T00:07:28 < aandrew> of course. I've shown her that she has absolutely no self control over her online time and interests so I am being forced to treat her this way
2018-11-05T00:07:47 < aandrew> I leave loopholes in on purpose and I give her chances to redeem herself by removing the restrictions without telling her to see what she does
2018-11-05T00:08:06 < antto> isn't it kinda hard to prevent them from getting internetz if they really want to?
2018-11-05T00:08:07 < aandrew> does she understand the purpose behind what then, perhaps I don't understand your question
2018-11-05T00:08:23 < aandrew> antto: absolutely not. The only access is through my router
2018-11-05T00:08:47 < aandrew> Cracki: of course not. she's 14 and thinks what she's doing doesn't matter
2018-11-05T00:09:20 < aandrew> she understands my goals, she understands my job as a parent is to teach her how to take care of herself and that includes being able to set personal limits and stick to them
2018-11-05T00:09:46 < aandrew> her incentives include more freedom online / screen time
2018-11-05T00:10:09 < aandrew> these are good questions by the way
2018-11-05T00:10:30 < antto> but.. all the cat gifs aren't going to watch themselves!
2018-11-05T00:11:16 < aandrew> Cracki: I tend to set my limits for her beyond where I expect her to set her own limits; she shouldn't hit them in normal use
2018-11-05T00:11:36 < aandrew> Cracki: and yes, personal limits are to be set by the person, but this is part of learning and education
2018-11-05T00:11:46 < aandrew> it's not like I have it locked down witout explanation or education
2018-11-05T00:11:51 < aandrew> heh
2018-11-05T00:13:08 < antto> dark with distant thunders
2018-11-05T00:13:31 < Steffanx> My main issue what getting home on time. Such easy childhood without internet or phone.
2018-11-05T00:14:24 < aandrew> Cracki: what do you mean?
2018-11-05T00:14:56 < aandrew> usually I don't set up limits until something egregious happens
2018-11-05T00:15:33 < aandrew> I am very much a fan of hands-off parenting and only setting up limits when it's either unsafe or when something has happened
2018-11-05T00:15:45 < aandrew> Cracki: with me most times it's very calm
2018-11-05T00:15:56 < aandrew> with my wife it's like the spanish inquisition
2018-11-05T00:16:01 < aandrew> out of nowhere and draconian
2018-11-05T00:16:02 < Steffanx> Haha
2018-11-05T00:16:32 < aandrew> yeah I'm not thrilled with it
2018-11-05T00:16:57 < aandrew> mostly and sadly for me it's just about until the kids are older (youngest is 6)
2018-11-05T00:17:09 < aandrew> I divorced with young kids once and I'd rather die than do that again
2018-11-05T00:17:44 < aandrew> it's ok now (they're 19 and 17) but I lost a lot of important time with them
2018-11-05T00:17:55 < aandrew> I married waaaay too early, kids too early and with the wrong person
2018-11-05T00:18:07 < aandrew> second time around I thought I got it right, but it was just a lot more ... subtle
2018-11-05T00:18:23 < aandrew> she's a good person, but just not for me. maybe we outgrew each other
2018-11-05T00:18:53 < antto> like butt cheekz during twerking

2018-11-05T03:48:39 < retrosenator> I need 1000x gain
2018-11-05T03:48:57 < retrosenator> so the adc to sample signal from 0-3 millivolts
2018-11-05T03:49:04 < retrosenator> and get full range
2018-11-05T03:49:14 < retrosenator> 250ksps

2018-11-05T03:49:42 < retrosenator> but is it possible to do in software somehow??
2018-11-05T03:50:07 < retrosenator> I was using 15mhz opamps
2018-11-05T03:50:31 < retrosenator> I was doing that yes
2018-11-05T03:50:37 < retrosenator> but what about the programmable gain?
2018-11-05T03:57:52 < retrosenator> nice but nowhere near enough for this
2018-11-05T03:57:56 < retrosenator> but very good to know

2018-11-05T04:00:45 < retrosenator> I guess adc with enough bits does that
2018-11-05T04:01:23 < retrosenator> hmm
2018-11-05T04:01:38 < retrosenator> interesting idea,  adc output is ideal, more information
2018-11-05T04:01:51 < retrosenator> it's sonar, so maybe comparator output would signify a return
2018-11-05T04:02:04 < retrosenator> but adc output would give information about what it hit
2018-11-05T04:02:29 < retrosenator> yeah lol
2018-11-05T04:02:55 < retrosenator> yeah
2018-11-05T04:03:07 < retrosenator> could even nbe < 1mV
2018-11-05T04:03:10 < retrosenator> if it's a weak return
2018-11-05T04:04:41 < retrosenator> usually .3 volts but good idea

2018-11-05T07:59:27 < emeb_mac> Gah - client just had a 2nd production run of an F7-based product and it won't run at the maximum rated 216MHz like the 1st run did.
2018-11-05T08:00:00 < emeb_mac> ST seems to be having trouble making F7s that meet the speed spec.
2018-11-05T08:00:32 < emeb_mac> of course
2018-11-05T08:00:41 < emeb_mac> for all the good that does
2018-11-05T08:02:05 < emeb_mac> I complained a few weeks ago - they told me "F7s only run at 200MHz with external DRAM" - I pointed out that I wasn't using external DRAM and they clammed up.
2018-11-05T08:02:46 < emeb_mac> not as far as I can see.
2018-11-05T08:03:55 < emeb_mac> Yeah - how long have these parts been out - 3 years now?
2018-11-05T08:04:26 < emeb_mac> the first batch I prototyped with ran fine @ 216, but lately I've been seeing lots of issues.
2018-11-05T08:06:02 < emeb_mac> so now I have to dial the frequency back and tweak the software capabilities. :P

2018-11-05T11:28:44 < zyp> L4 does have FPU?
2018-11-05T11:29:00 < Sadale> Why FPU is needed at all?
2018-11-05T11:29:16 < Sadale> Doesn't audio processing with integer arithematics work?
2018-11-05T11:29:56 < zyp> https://www.st.com/content/st_com/en/about/media-center/press-item.html/p3926.html <- there's already a bunch of stuff available
2018-11-05T11:30:11 < zyp> ST has some voice recognition demos somewhere too, IIRC
2018-11-05T11:30:22 < Sadale> Apparently STM32L4 has something called "Serial Audio Interface"
2018-11-05T11:30:36 < Sadale> I'm not entirely sure what it really does, tho
2018-11-05T11:30:37 < sk_tandt> Yep, I am trying my luck with DSP concepts, and I've found some pregress explorations by Spelgatti (who's objectively awesome)

2018-11-05T11:32:55 < sk_tandt> Good point, but it was my mistake
2018-11-05T11:32:55 < Sadale> ahh. I see.
2018-11-05T11:32:59 < sk_tandt> Speech recognition it is
2018-11-05T11:33:40 < sk_tandt> Ahahahaha, thanks <3
2018-11-05T11:33:49 < Sadale> Justa obtain the signal Do fourier transform, get the formants and you'll get the vowels rather easily. The first three formants should be enough.
2018-11-05T11:34:09 < Sadale> For consonants, again, I've no idea :P
2018-11-05T11:35:27 < sk_tandt> Haohmaru: does the STM32 have such luxuries?
2018-11-05T11:35:51 < sk_tandt> If I had network connectivity, I'd cloud the problem to death
2018-11-05T11:35:51 < sk_tandt> RNN
2018-11-05T11:36:03 < Sadale> train the network offline?
2018-11-05T11:36:20 < Sadale> It's going to take a while to implement it and perform the training on the chip.
2018-11-05T11:36:55 < sk_tandt> I did, but I was utterly oblivious to the possibility of neural networks on an STM32!
2018-11-05T11:36:56 < Sadale> Anyway I hope that sk_tandt isn't really having the problem of offline speech recognition with STM32L4.
2018-11-05T11:37:14 < sk_tandt> Sadale: I really do, pray for me
2018-11-05T11:37:18 < Sadale> sk_tandt, ow.

2018-11-05T11:38:17 < sk_tandt> Haohmaru: considering I have multiple (and unknown) voice sources to train against, how fast do you suppose the STM32 will be able to iterate? I could ballpark the estimate with TensorFlow, but here I'm literally clueless
2018-11-05T11:38:36 < zyp> why would you train on stm32?
2018-11-05T11:38:44 < Sadale> because Haohmaru suggested that?

2018-11-05T11:39:11 < Sadale> I'm sorry. I lied :3
2018-11-05T11:39:34 < zyp> train the network on a GPU, then copy the gains or whatever they are called to the stm32 after it's trained
2018-11-05T11:39:46 < Sadale> I think he wants it offline somehow.
2018-11-05T11:39:57 < zyp> the training or the usage?
2018-11-05T11:40:11 < Sadale> no idea.
2018-11-05T11:40:18 < sk_tandt> zyp: the usage only, thankfully
2018-11-05T11:40:25 < Sadale> Oh. I get the idea.
2018-11-05T11:40:37 < sk_tandt> I'm not certain about what you mean with gains 'tho: plz details
2018-11-05T11:40:39 < Sadale> I had the impression that you guys were talking about training it right inside the STM32

2018-11-05T11:41:55 < Sadale> I guess what he meant is train the data outside the microcontroller. Then you'll get all those trained parameters. Then hard-code the trained parameters into the STM32.
2018-11-05T11:42:04 < zyp> yes

2018-11-05T11:43:13 < Sadale> The theory isn't difficult. But I wonder how difficult it is in practice.
2018-11-05T11:43:21 < sk_tandt> Sadale: it isn't, but it's viable AND there are pre-trained models

2018-11-05T12:21:09 < karlp> Maxoul: so, use the hal then?
2018-11-05T12:21:33 < karlp> jadew: it woudl seem to me to be a way of just addign up unreliability
2018-11-05T12:21:36 < Maxoul> can't anymore for a nfc driver I'm developping
2018-11-05T12:22:04 < Maxoul> why everybody but me have a "stm32f4xx_rcc.h" file for example...
2018-11-05T12:22:14 < Maxoul> (same for gpio, etc.)
2018-11-05T12:22:43 < srk> lol
2018-11-05T12:22:47 < Maxoul> I have a stm32f4xx_hal_rcc.h but it doesn't define RCC_AHB1PeriphClockCmd...
2018-11-05T12:22:50 < jadew> karlp, it's possible it's the next gen fake SSD
2018-11-05T12:22:59 < karlp> Maxoul: that's the stdperiph lib interface, 
2018-11-05T12:23:09 < karlp> you may be interested in the _ll_ interfaces,
2018-11-05T12:23:18 < karlp> but these dont' really mix and match all together very well.
2018-11-05T12:23:30 < karlp> also, why "can't anymore" ?
2018-11-05T12:23:44 < Maxoul> ll = stdperiph ?
2018-11-05T12:24:15 < karlp> no, stdperiph = stdperiph
2018-11-05T12:24:20 < Maxoul> because so far I was ok just to use HAL calls, but I'm currently testing a driver/example for RC422 RFiD card reader found on github
2018-11-05T12:24:37 < karlp> ll = lowlevel, the new one because people were unhappy with hal
2018-11-05T12:24:50 < karlp> just convert the code
2018-11-05T12:24:56 < karlp> it wil only be api call names
2018-11-05T12:25:37 < Maxoul> did that means that all codes found on github with "stm32f4xx_yyy" includes are kind of obsoletes ?
2018-11-05T12:25:40 < karlp> jadew: this one appears to have footprints for flash on the back, and sdcards on the front, so would definitely be a more tradidiotional harddrive: https://www.aliexpress.com/item/10-ports-Micro-SD-TF-Memory-Card-to-SATA-SSD-Adapter-with-RAID-Quad-2-5/32848612759.html
2018-11-05T12:26:00 < karlp> stdperiph isn't provided for all targets, but you can still find it aroundthe places
2018-11-05T12:26:07 < karlp> it's definitely not supported by ST going forward.
2018-11-05T12:26:17 < Maxoul> damn
2018-11-05T12:26:49 < Maxoul> I didn't though stm32 was such a graveyard :/
2018-11-05T12:27:26 < karlp> that's an interesting perspective on the word graveyard
2018-11-05T12:27:40 < karlp> you found some old code online, and you tried to mix it with another API and ... ?
2018-11-05T12:27:59 < karlp> if you want to copy/paste, perhaps try mbed or arduino?
2018-11-05T12:28:00 < Maxoul> No, there is *only* old code online
2018-11-05T12:28:14 < Maxoul> so far that I found ofc
2018-11-05T12:28:36 < karlp> mayb rc422 is dead and no-one else cares anymore? or it's trivially portable to hal/ll/alternatives
2018-11-05T12:28:56 < Maxoul> might be that too
2018-11-05T12:29:46 < Maxoul> anyway thanks karlp for the clarification
2018-11-05T12:29:52 < Maxoul> appreciated
2018-11-05T12:30:12 < karlp> f4 might still have stdperiph lib available if you look harder
2018-11-05T12:30:21 < karlp> but I don't think cubemx will offer it 
2018-11-05T12:30:33 < Maxoul> I found it on official ST site yes
2018-11-05T12:30:59 < karlp> https://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32-standard-peripheral-libraries/stsw-stm32065.html
2018-11-05T12:31:12 < Maxoul> but as you said, rewriting it for the HAL might be a better idea
2018-11-05T12:31:25 < karlp> and might not actually be very difficult.
2018-11-05T12:31:40 < karlp> what's the github repo you'ðre looking at? (just for my own curiosity)
2018-11-05T12:31:50 < Maxoul> as I 1) personnaly find it nice to use 2) i'm currently testing platforms & mcu and a lil' abstraction should not harm
2018-11-05T12:31:54 < karlp> (aka, it's monday morning and it's chilly and I'm avoiding my own work)
2018-11-05T12:32:09 < Maxoul> don' tell me bout that :p
2018-11-05T12:32:31 < Maxoul> for example this one: https://github.com/zthxxx/STM32-Contiki_Sensor_Smart_Home/blob/master/Hardware/RC522/RC522.h
2018-11-05T12:32:45 < Maxoul> or this one https://github.com/ninharp/STM32F103_RFID_Access_Control/blob/master/lib/tm_mfrc522.h
2018-11-05T12:32:59 < Maxoul> and this one too https://stm32f4-discovery.net/2014/07/library-23-read-rfid-tag-mfrc522-stm32f4xx-devices/
2018-11-05T12:33:23 < karlp> porting contiki code will probably be harder than porting stdperiphlib to hal
2018-11-05T12:34:37 < Maxoul> oh no wrong link, first one should be https://github.com/MaJerle/stm32f429/blob/master/00-STM32F429_LIBRARIES/tm_stm32f4_mfrc522.c
2018-11-05T12:34:42 < Maxoul> anyway

2018-11-05T12:38:28 < karlp> that ninharp one has some fairly suspect code in it, but *shrugs* functional I guess
2018-11-05T12:39:28 < karlp> good lucking building it though, I wonder how good eclipse is at really storing settings
2018-11-05T12:40:16 < karlp> heh, using dwt for millisecond and upd elays, and counting uptime.
2018-11-05T12:42:45 < qyx> much fast?
2018-11-05T12:53:06 < qyx> wtf why are people using typedef'd byte?
2018-11-05T12:53:29 < qyx> is uint8_t that much longer or what
2018-11-05T12:55:40 < qyx> also byte *data, byte length
2018-11-05T12:56:19 < karlp> because they probably ported some arduino code ;)

2018-11-05T14:03:26 < mawk> so char is the same length as byte

2018-11-05T14:05:56 < karlp> pretending that char will always be the signed/unsigned you think is a definite trap.

2018-11-05T18:05:17 < mawk> lol
2018-11-05T18:05:18 < mawk> yeah
2018-11-05T18:05:28 < mawk> well I was looking for a new language to use for system stuff, in place of C
2018-11-05T18:05:48 < karlp> so what's "system stuff" for you then?
2018-11-05T18:05:49 < mawk> lots of people said rust, but it seems they only spent time on the memory part of the language and not much on the rest
2018-11-05T18:06:13 < mawk> system programming on PC
2018-11-05T18:06:16 < karlp> because for me, I get ~all the performance I need just using python and and all the ease of use.
2018-11-05T18:06:22 < karlp> yeah, but what's "system programming"
2018-11-05T18:06:27 < mawk> so that needs easy integration with C libraries, access to inline assembly, etc
2018-11-05T18:06:39 < karlp> you really need inline assembly? :)
2018-11-05T18:06:41 < karlp> _really_?
2018-11-05T18:06:54 < karlp> you're stuck with c/c++ then, so making up absurd goals :)
2018-11-05T18:06:58 < mawk> well networking, threads, syscalls, device files, etc
2018-11-05T18:07:13 < mawk> it's not a need, it's just a criteria to find a "system" language
2018-11-05T18:07:21 < mawk> I don't need inline assembly
2018-11-05T18:07:29 < karlp> I'm just saying, most people don't need a "system" language, 
2018-11-05T18:07:33 < karlp> even if they think they do
2018-11-05T18:08:13 < qyx> speaking of python, have you tried micropython ported in a larger C project?

2018-11-05T18:08:44 < karlp> what do you mean, using micropython on the desktop because it's "smaller" ? or what?
2018-11-05T18:08:45 < mawk> the things I need is easy linking with usual C shared libraries, all the syscalls, being able to make C-style structs without having to make a correspondance between C structs and native structs
2018-11-05T18:08:48 < mawk> that sort of thing
2018-11-05T18:09:38 < karlp> ease of using existing C .sos, is always goign to be where verious languages go from "sane" to "insane" fairly quickly.

2018-11-05T18:09:49 < karlp> but if enough of it is already available, *shrugs*
2018-11-05T18:10:20 < karlp> making c style structs without having to make a struct map wat?
2018-11-05T18:10:33 < karlp> you're making rules are pretty much, "it must be c/c++"
2018-11-05T18:10:45 < qyx> no, having an embedded C project which embeds a micropython interpreter for scripting/other purposes
2018-11-05T18:10:55 < mawk> at least D and somewhat python satisfy that requirement
2018-11-05T18:11:15 < karlp> show me your declared c structs in python?
2018-11-05T18:11:39 < mawk> with ctypes
2018-11-05T18:11:53 < karlp> qyx: not I, I'm also onlyusing lua on openwrt scale stuff, not baremetal stuff elua style.
2018-11-05T18:12:27 < karlp> mawk: if you call ctypes "making c structs without having to corrspond between types" then ok, we have different interpretations :)
2018-11-05T18:12:27 < mawk> class C(ctypes.Structure): _fields_ = [('field1', ctypes.c_int), ('field2', ctypes.c_int)]
2018-11-05T18:13:01 < mawk> I mean without having to pass an opaque binary buffer to the syscall and get out one by one the fields to native types
2018-11-05T18:13:14 < karlp> see that looks nothing like a c struct, but a lot like a language specific way of specifying how to map things.
2018-11-05T18:13:29 < mawk> yeah
2018-11-05T18:13:31 < mawk> and it's not manual
2018-11-05T18:13:37 < mawk> but that's why I said "somewhat" for python
2018-11-05T18:14:04 < mawk> also cffi does it all by itself by parsing the header file
2018-11-05T18:17:20 < karlp> autogenerated stuff tends to be "functional, yet gross and painful" most of the time.

2018-11-05T18:19:29 < kakimir> I have under 1% error across voltage range, ex. around 4.8 there is around 1% error

2018-11-05T18:20:03 < mawk> I don't get how you do that kakimir, the temperature isn't like noise, no ?
2018-11-05T18:20:23 < mawk> how can you compensate the 4% error we saw the other day
2018-11-05T18:20:27 < kakimir> I don't understand what you are saying
2018-11-05T18:20:40 < kakimir> next I need to input temperature instead of fixed value
2018-11-05T18:21:07 < mawk> so you're using the curves in the datasheet to remove the error then 
2018-11-05T18:21:13 < mawk> or something
2018-11-05T18:21:49 < kakimir> yes
2018-11-05T18:21:55 < kakimir> interpolating in 2 functions
2018-11-05T18:21:59 < kakimir> first temperature
2018-11-05T18:22:04 < mawk> ah
2018-11-05T18:22:04 < kakimir> then voltage
2018-11-05T18:22:13 < mawk> you're interpolating the curves of the datasheet
2018-11-05T18:22:13 < kakimir> on attiny
2018-11-05T18:22:24 < kakimir> only voltage ranges I find useful
2018-11-05T18:23:02 < kakimir> so the value moves inside that "box" we talked about
2018-11-05T18:23:06 < mawk> yes
2018-11-05T18:23:08 < kakimir> depending on stuff
2018-11-05T18:23:11 < mawk> how good is your interpolation ?
2018-11-05T18:23:14 < mawk> for the temperature
2018-11-05T18:23:16 < kakimir> too big.
2018-11-05T18:23:26 < mawk> because there are only three points shown in the datasheet
2018-11-05T18:23:33 < mawk> 80°C 25°C and -40°C or something
2018-11-05T18:23:39 < kakimir> idk really
2018-11-05T18:23:51 < kakimir> I think it can be better than nothing
2018-11-05T18:23:54 < mawk> maybe there's the general formula somewhere you can use
2018-11-05T18:23:58 < mawk> to improve that interpolation thing
2018-11-05T18:25:06 < kakimir> if it can't replace expensive operations with bitshifts it's no use
2018-11-05T18:25:19 < mawk> you can tabulate the values at startup
2018-11-05T18:25:22 < mawk> and keep it in memory
2018-11-05T18:25:30 < mawk> ah no, you have very few memor
2018-11-05T18:25:31 < mawk> y
2018-11-05T18:25:34 < kakimir> you mean instead of interpolating
2018-11-05T18:25:37 < kakimir> I would use table?
2018-11-05T18:25:43 < kakimir> no man
2018-11-05T18:25:47 < mawk> no, you would compute the table at startup
2018-11-05T18:25:51 < mawk> using the expensive formula
2018-11-05T18:25:56 < mawk> and store table somewhere for quick use
2018-11-05T18:26:03 < mawk> but it doesn't work with your ram size
2018-11-05T18:26:05 < kakimir> I have 128bytes of sram

2018-11-05T22:01:38 < catphish> i'm too lazy to engineer this myself, so perhaps someone can just give me a solution: someone wants 10+ RFID readers with external antennas connected to a single USB connection, on a budget
2018-11-05T22:02:08 < catphish> there seem to be plenty of very very cheap RFID readers but they have uart outputs, not sure how best to multiplex them
2018-11-05T22:03:38 < catphish> so perhaps something with lots of uart, or a low cost rfid (maybe nfc) device with the ability to use an exernal antenna and an spi/i2c interface
2018-11-05T22:06:02 < c10ud> just put a virtual uart on the usb
2018-11-05T22:06:12 < c10ud> and connect through a hub
2018-11-05T22:07:19 < PaulFertser> catphish: isn't "lots of uart" exactly the excuse you needed to use an FPGA for some real job? ;)
2018-11-05T22:07:47 < kakimir> _Budget_

2018-11-05T22:08:12 < catphish> c10ud: do you mean just lots of individual usb-uart adapters? on a usb hub?
2018-11-05T22:08:34 < c10ud> i guess that's the cheapest option, like 10$
2018-11-05T22:09:25 < catphish> i am looking at whole RFID reader setups with uart outputs that only cost around $6
2018-11-05T22:09:39 < catphish> so hoped there might be a cheap way to bulk connect them
2018-11-05T22:10:39 < c10ud> https://www.ebay.com/p/Cp2102-USB-2-0-to-TTL-UART-Module-6pin-Serial-Converter-STC-Replace-Ft232-Module/1479714412?iid=381374541932

2018-11-05T22:13:15 < c10ud> catphish, that's the 1st I found, but depending on distance you might want to get the ones with a mini/micro usb out
2018-11-05T22:14:52 < PaulFertser> How about emulating many uarts on a single stm32?
2018-11-05T22:15:38 < catphish> PaulFertser: i did think about that, at 9600 baud, do you think there's time to manually receive a few channels of uart?
2018-11-05T22:15:51 < catphish> seems like there would be actually
2018-11-05T22:16:05 < Steffanx> so many options. Could even add some spi-uart ic
2018-11-05T22:16:12 < PaulFertser> catphish: st claims they can do 115200 on one emulated uart.
2018-11-05T22:16:52 < catphish> PaulFertser: i don't know how that translates to 10 uarts, but... this actually seems like a really neat idea now that i think about it
2018-11-05T22:17:44 < catphish> could potentially use interrupts and timers to time the time between state changes on each pin, then calculate the incoming bits
2018-11-05T22:19:18 < Steffanx> perfect job for a fpga though :P
2018-11-05T22:19:30 < Steffanx> time to learn vhdl or verilog ( or whatever you prefer )
2018-11-05T22:19:45 < catphish> i'm not that familiar with FPGAs, is it easy to make a uart?

2018-11-05T22:25:29 < Steffanx> i'd go with hw/sw uart or some spi-uart ics
2018-11-05T22:25:49 < catphish> seems like something where you have to recover the clock from the signal would be among the hardest
2018-11-05T22:28:07 < Steffanx> there are stm32 with 8 uarts
2018-11-05T22:28:14 < Steffanx> (at least that's what cube tells me)
2018-11-05T22:28:50 < catphish> a row of these might be the best option: https://uk.farnell.com/nxp/sc16is740ipw-128/uart-1-ch-5mbps-tssop-16/dp/2776217
2018-11-05T22:29:30 < catphish> uart interface ICs are actually bizarrely expensive

2018-11-05T22:46:32 < Steffanx> Even a 4 channel uart-spi ic is only like 4-5 euro. Two of those and you dont need the usb ic when you pick a usb stm32
2018-11-05T22:46:59 < catphish> there's no stm32 with usb and multiple uarts
2018-11-05T22:47:23 < catphish> so probably better just to get a USB uart IC, which will also handle the 3v3 supply
2018-11-05T22:47:32 < catphish> then chain a couple of stm32s to it
2018-11-05T22:47:45 < Steffanx> My search showed there is an f0 with usb and 4 uarts
2018-11-05T22:48:17 < catphish> will the stm32 also handle power supply?
2018-11-05T22:48:18 -!- c10ud^ [~c10ud@emesene/dictator/c10ud] has joined ##stm32
2018-11-05T22:48:56 < Steffanx> Just usb the bus power?
2018-11-05T22:49:13 < catphish> ie convert usb bus power to 3v3 to power itself and another stm32
2018-11-05T22:49:37 < catphish> night :)
2018-11-05T22:50:03 < catphish> bedtime boys 3: army boys
2018-11-05T22:51:05 < Steffanx> Just use a cheaparse ldo catphish ?
2018-11-05T22:51:16 < catphish> hmm yeah, duh

2018-11-05T22:51:51 < catphish> so i just need to check the ICs can do all their usarts plus spi at the same time
2018-11-05T22:52:13 < catphish> then all i'd need is 2 STM32s and a LDO and i'll get 12 UARTs

2018-11-05T22:52:48 < catphish> or worst case scenario, i lose a UART from each and stil reach my target of 10
2018-11-05T22:54:44 < Steffanx> its funny how a stm32 with 8 uarts with a shit load of ram is cheaper than a dedicated UART IC with only 128 Bytes/uart.
2018-11-05T22:55:47 < malinus> god bless arm
2018-11-05T22:56:12 < aandrew> heh
2018-11-05T22:56:21 < aandrew> it's not to do with arm, just good vendors
2018-11-05T22:56:34 < aandrew> sam3 has some amazing parts too and cheap as shit
2018-11-05T22:56:47 < aandrew> apparently sam3u is 480mbps capable and cheap
2018-11-05T22:56:48 < Steffanx> i didnt hate efm32 either.
2018-11-05T22:56:50 < aandrew> just a lot of pins
2018-11-05T22:57:19 < Steffanx> only thing i hate about atmel and silabs is the IDE crap (which you obviously dont have to use but ... )
2018-11-05T22:57:21 < catphish> Steffanx: it is a little mad
2018-11-05T22:57:52 < Steffanx> oh and Atmel libs are terrible.
2018-11-05T22:57:56 < Steffanx> i should say microchip.
2018-11-05T23:00:08 < karlp> aandrew: was it you or englishman using sam4e or something, (the new ones) and finding a bunch of errata.
2018-11-05T23:00:11 < karlp> they look nice though
2018-11-05T23:02:17 < aandrew> I found a shitton of errors at the start of the year on SAM4, englishman probably found a shitload more
2018-11-05T23:02:31 < aandrew> yeah they are cheap and powerful, but it looks like it may be headache-inducing to work with them
2018-11-05T23:02:33 < karlp> catphish: there's a few projects doing dual usb-uart on stm32, and at least one with three that I've seen, but I can't find it right now.
2018-11-05T23:02:35 < catphish> Steffanx: so yes, i can do STM32F070CBT (4xUSART + 1xSPI + 1xUSB) and STM32F091RCT (8xUSART + 1xSPI)
2018-11-05T23:02:40 < malinus> Steffanx: well goot thing about 8-bit is thatyou don't really need libs :P
2018-11-05T23:02:56 < aandrew> heh
2018-11-05T23:03:28 < catphish> so 2 of them clained with SPI can do USB to 12xUART for a cost of £5.39
2018-11-05T23:03:28 < karlp> jpa-: glad to hear abotu wcid working, there's a PR on locm3 to support the special string indices it asks for.
2018-11-05T23:03:44 < malinus> working on 32-bit with no libs are less fun though
2018-11-05T23:03:59 < catphish> i don't use libs, except constants
2018-11-05T23:04:15 < catphish> but thats just a matter of personal taste / autism
2018-11-05T23:04:19 < karlp> cp2108*2 + terminus tech usb hub chip..
2018-11-05T23:04:44 < catphish> karlp: it would be 3 of those
2018-11-05T23:04:56 < karlp> whatever uyou need,
2018-11-05T23:04:59 < malinus> catphish: just defines on stm32? Or LL?
2018-11-05T23:05:07 < karlp> but yeah, usb2serial chips + usb hub is going to be "easiest"
2018-11-05T23:05:13 < catphish> malinus: LL?
2018-11-05T23:05:14 < karlp> the rest of it is software wankery
2018-11-05T23:05:22 < karlp> unless you're planning on making enough to offeset the sw dev cost
2018-11-05T23:05:32 < malinus> catphish: low level library - mostly just structs/defines
2018-11-05T23:05:45 < malinus> timer->crc etc.
2018-11-05T23:05:56 < catphish> malinus: yeah, i use the official libs i guess, but only for the defined they provide
2018-11-05T23:06:02 < catphish> *defines
2018-11-05T23:06:20 < catphish> malinus: yeah i use those
2018-11-05T23:06:22 < malinus> catphish: "offical libs". That could be a number of things in 2018 :P
2018-11-05T23:07:01 < catphish> malinus: specifically i use STM32Cube_FW, i never considered that to be a library, but actually that's bullshit
2018-11-05T23:07:02 < malinus> stm32 have a 30 page slideshow trying to explain their current libs situations
2018-11-05T23:07:09 < catphish> malinus: it provides a LOT of help
2018-11-05T23:07:53 < catphish> it allows me to do things like FEATURE->REGSTER = SETTING | OTHER_SETTING
2018-11-05T23:09:29 < catphish> i'm actually not sure whether to create a generic device that simulates 12 serial ports, of a proprietary device that simulates a single serial port and just outputs lines prefixed with which port they came from
2018-11-05T23:09:35 < malinus> what about LED_GREEN(ON). PWM_PB4_(120khz, 20%)->start()?!
2018-11-05T23:09:47 < catphish> malinus: yeah i don't do that
2018-11-05T23:09:50 < malinus> ;)
2018-11-05T23:10:06 < catphish> my taste is for manipulating each register individually
2018-11-05T23:10:15 < malinus> catphish: I'm yet to see that elaborate library. Well except maybe arduino, but that's slow as fuck
2018-11-05T23:10:33 < catphish> even though it usually ends up that i have to waste time writing my own heelpers
2018-11-05T23:10:36 < malinus> I think libopencm3 comes close 2nd but faster

2018-11-05T23:13:21 < catphish> i may even be able to build the rfid readers onto my own board
2018-11-05T23:15:24 < catphish> that opens a new can of worms though, since the rfid readers are just an MCU and an op amp

2018-11-05T23:24:21 < Steffanx> 8
2018-11-05T23:28:32 < catphish> i might just build 10 these https://www.serasidis.gr/circuits/RFID_reader/images/125kHz_RFID_reader_schem.GIF
2018-11-05T23:28:38 < catphish> then i only need one MCU
2018-11-05T23:29:08 < Steffanx> Attiny. Go away. Pleasse
2018-11-05T23:30:14 < catphish> lol
2018-11-05T23:30:27 < catphish> well minus the attiny and the power supply and the uart and the buzzer
2018-11-05T23:30:41 < catphish> 10 of those can be hooked up to a single stm32
2018-11-05T23:31:20 < Steffanx> 10x the effort.
2018-11-05T23:31:31 < Steffanx> But you have a pick and placer 
2018-11-05T23:31:35 < karlp> catphish: how? you still need 10 uarts?
2018-11-05T23:31:49 < catphish> no need for any uarts
2018-11-05T23:31:55 < karlp> or are you now going to do the software for 10 soft rx ttls?
2018-11-05T23:32:00 < catphish> the stm32 can take the place of 10 of those attinys
2018-11-05T23:32:23 < catphish> no uart needed
2018-11-05T23:33:57 < catphish> someone wants to detect the location of some model trains :)
2018-11-05T23:34:24 < catphish> they want to put coils under the track and connect them back to usb
2018-11-05T23:35:13 < catphish> so i can replicate the analog portion of this circuit 10 times https://www.serasidis.gr/circuits/RFID_reader/images/125kHz_RFID_reader_schem.GIF
2018-11-05T23:35:35 < catphish> and "PB1" can be 10 inputs of an stm32
2018-11-05T23:36:04 < catphish> oh right, yes
2018-11-05T23:36:04 < karlp> if you're after a sw dev project sure ...
2018-11-05T23:36:14 < karlp> how many of these are you going to make again?
2018-11-05T23:36:27 < catphish> karlp: 1 :)
2018-11-05T23:36:31 < catphish> but i want it to be good
2018-11-05T23:36:43 < karlp> you're insane :)
2018-11-05T23:37:15 < catphish> can bus might be cool, but i can make this seriously cheap if one stm32 just drives all 10 coild
2018-11-05T23:37:18 < catphish> *coils
2018-11-05T23:37:56 < catphish> it's either that, or make my USB to 10x UART interface, and buy 10 pre-made rfid readers
2018-11-05T23:38:53 < catphish> yeah i was thinking the line between the coils and the reader might be a problem
2018-11-05T23:38:58 < catphish> so probably better to have modules
2018-11-05T23:39:21 < catphish> if i *make* the modules, that line can be CAN
2018-11-05T23:39:42 < karlp> have you finished the other nfc+timing project yet?
2018-11-05T23:40:08 < catphish> karlp: almost :)
2018-11-05T23:40:43 < catphish> this one is more of a favour for someone else, just happened to be something i know a bit about

2018-11-05T23:41:07 < catphish> Cracki: in that diagram the attiny drives the coil and looks at the output from he coil, converts the pattern to UART
2018-11-05T23:41:26 < catphish> Cracki: that's correct, it's been digitized by that point
2018-11-05T23:41:51 < catphish> is line length likely to be a problem for 3v3 digital?
2018-11-05T23:42:10 < catphish> yeah, only 2 lines are needed, the fet output and input from comparator
2018-11-05T23:43:00 < kakimir> attiny mentioned
2018-11-05T23:43:33 < catphish> well the uart is not needed at all if the comparator output goes straight to the USB IC
2018-11-05T23:44:10 < catphish> an stm32 can do USB and simultaneously so what that attiny does
2018-11-05T23:44:24 < catphish> *do what
2018-11-05T23:44:40 < kakimir> I'm looking at attinys
2018-11-05T23:44:49 < kakimir> atm.
2018-11-05T23:44:54 < catphish> Cracki: in this case that is what i was referring to yes, sorry
2018-11-05T23:45:23 < kakimir> attiny816 scares me
2018-11-05T23:45:25 < catphish> so 1) stm32 connects to usb 2) it generates an output to the FET(s) 3) it collects the results from the comparator(s)
2018-11-05T23:45:28 < kakimir> but it has potential
2018-11-05T23:46:00 < catphish> only needs one pin for the clock output, plus one input per coil
2018-11-05T23:47:04 < kakimir> hmm!
2018-11-05T23:49:00 < catphish> the real question is whether line length to the coil matters
2018-11-05T23:49:09 < catphish> if not, i'll put it all on one board
2018-11-05T23:49:26 < kakimir> Cracki: how about divider?
2018-11-05T23:49:44 < catphish> Cracki: wire from the coil to the board
2018-11-05T23:49:54 < catphish> coil, long wire, board

2018-11-06T00:39:55 < antto> youtube comments are the hotspot for wisdom
2018-11-06T00:39:56 < jadew> the guy made the point that babies are less valuable, because it takes less time and effort to make another one at the same level than an adult
2018-11-06T00:40:11 < jadew> but we're just wired the wrong way
2018-11-06T00:40:48 < jadew> he kinda had a point, but for some reason the thought terrifies me

2018-11-06T00:42:08 < antto> afrika so far
2018-11-06T00:42:18 < antto> imma look at ghettos here
2018-11-06T00:43:23 < jadew> yeah, it makes sense, but it feels scary to think about it - probably because we're made to fear for kid's safety
2018-11-06T00:43:28 < antto> however, death of a young child kinda leaves quite an amount of pain on a bunch of adults around it

2018-11-06T01:07:50 < zyp> I used this angle copier thing which gave me a pretty decent starting point, and then I made some additional test cuts to make sure I could operate the saw precisely enough to get consistent results

2018-11-06T01:33:35 < Laurenceb124> about $150/unit in large quantities for their 27W, 1m long unit

2018-11-06T01:34:07 < catphish> now just to decode it
2018-11-06T01:34:10 < Laurenceb124> not quite as wtf as I expected, but still makes no economic sense
2018-11-06T01:35:01 < Laurenceb124> I have a paper design for 1m long rail mounted unit using 100W and costing about $130
2018-11-06T01:36:42 < zyp> are you making a cannabis farm or what's the context here?
2018-11-06T01:37:26 < Laurenceb124> zyp: nah just considering selling LED horticultural lighting
2018-11-06T01:37:47 < zyp> why?
2018-11-06T01:38:05 < Laurenceb124> I while ago I created some multiphysics modelling for optimised light design
2018-11-06T01:38:38 < Laurenceb124> nobody seems to be making low cost passively cooled units using minimal metal parts
2018-11-06T01:38:44 < zyp> isn't there plenty of existing shit already?
2018-11-06T01:39:07 < zyp> I mean, even ikea sells LED growlights, I bought some last year
2018-11-06T01:39:16 < Laurenceb124> well there was a uni project I was semi involved with costing megabux to develope this idea
2018-11-06T01:39:16 < zyp> ref. https://bin.jvnv.net/file/1l1NU.jpg
2018-11-06T01:39:21 < Laurenceb124> and they failed epically
2018-11-06T01:39:49 < Laurenceb124> but I managed to meet all their goals with multiphysics based design optimisation earlier this year
2018-11-06T01:41:12 < Laurenceb124> interesting thanks
2018-11-06T01:41:21 < Laurenceb124> looks v low power though
2018-11-06T01:42:04 < Laurenceb124> uni design goals were ~200W per linear meter, ~55% efficiency, 50khours lifetime
2018-11-06T01:42:27 < Laurenceb124> payback time <10years versus HPS
2018-11-06T01:43:32 < zyp> hmm, looks like they are discontinued, ikea now only has some growlight led bulbs
2018-11-06T01:43:46 < Laurenceb124> the Phillips units are 27W/m, ~50% efficiency, ??k hours (users are complaining Phillips lied about lifetime), negative payback time
2018-11-06T01:44:39 < Laurenceb124> the uni guys basically gave up as they thought it was close to impossible to beat HPS under realistic economics, even with improved LEDs
2018-11-06T01:44:41 < zyp> what do you mean by W/m?
2018-11-06T01:44:56 < Laurenceb124> this stuff mounts to 40mm steel rails
2018-11-06T01:45:07 < Laurenceb124> they are already set up in the glasshouses
2018-11-06T01:45:18 < Laurenceb124> so how many watts input power per meter of rail
2018-11-06T01:45:23 < zyp> ah
2018-11-06T01:45:43 < zyp> well, you could just scale up in width, no?
2018-11-06T01:46:07 < sync> we have some osram shop light shit
2018-11-06T01:46:11 < sync> gets real hot tho
2018-11-06T01:46:40 < Laurenceb124> yeah to keep high efficiency and lifetime you need die temp below 65C or so
2018-11-06T01:46:50 < sync> interestingly the failure mode is the silicone dome going to shit
2018-11-06T01:46:51 < Laurenceb124> its very hard with passive cooling
2018-11-06T01:48:02 < zyp> I checked the ikea unit, it's 16W, bit less than half a meter long
2018-11-06T01:48:12 < Laurenceb124> a huge heatsink makes it too expensive -> the payback time is >10years
2018-11-06T01:48:56 < Laurenceb124> but anyway I came up with an extruded alu heatsink that worked in multiphysics and got quote of $14/m for it manufactured
2018-11-06T01:49:28 < sync> that's not hard tho
2018-11-06T01:49:37 < sync> custom extrusions are often the way to go
2018-11-06T01:50:00 < Laurenceb124> yeah but I might be able to sell quite a few before others catch on
2018-11-06T01:50:08 < Laurenceb124> if I find the right distributor
2018-11-06T01:50:19 < sync> idk
2018-11-06T01:50:55 < Laurenceb124> the goals the uni guys set seem very sane for horticultural installations
2018-11-06T02:02:36 < catphish> omg, serious newbie question, how on earth do i turn off a channel on my oscilloscope, i turned it on and now it's in my way
2018-11-06T02:02:54 < zyp> catphish, push the channel button again?
2018-11-06T02:03:21 < catphish> zyp: that does nothing :( it's a hmo1024
2018-11-06T02:04:08 < catphish> suppose i could rtfm
2018-11-06T02:04:51 < jadew> catphish, try pushing it again
2018-11-06T02:05:02 < jadew> first time it gets selected, second time it should turn off
2018-11-06T02:05:07 < catphish> i pushed it like 6 times :(
2018-11-06T02:05:24 < catphish> jadew: oh, that suddenly works
2018-11-06T02:05:39 < catphish> no idea why, i was pressing it repeatedly before
2018-11-06T02:05:41 < zyp> haha
2018-11-06T02:05:48 < sync> yeah the scanrate on some of them sucks
2018-11-06T02:06:22 < catphish> oh, if the scope is holding, it doesn't turn it off
2018-11-06T02:06:27 < jadew> catphish, does your scope do custom BW?
2018-11-06T02:06:27 < catphish> if it's running it works :)
2018-11-06T02:06:59 < catphish> jadew: a limited selection i think, i'm not very familiar with it
2018-11-06T02:07:19 < catphish> it's not mine, just borrowing it, but really want to buy one now
2018-11-06T02:07:27 < jadew> well, if it's a selection it's still better than my only 20 MHz on/off
2018-11-06T02:07:29 < catphish> it's sexy as hell by my standards
2018-11-06T02:07:58 < catphish> looks like the immediate options are 20MHz or "full"
2018-11-06T02:08:10 < catphish> so maybe thats all
2018-11-06T02:08:19 < jadew> yeah...
2018-11-06T02:08:49 < jadew> I had a very hard time this weekend trying to trigger on some signals and having multiple options for filters would have helped a lot

2018-11-06T02:30:07 < catphish> i'm working from this design - https://www.serasidis.gr/circuits/RFID_reader/images/125kHz_RFID_reader_schem.GIF - not really sure why it goes twice through the opamp
2018-11-06T02:35:02 < aandrew> first opamp (ic2a) is a comparator
2018-11-06T02:35:19 < aandrew> er wait
2018-11-06T02:35:21 < jadew> I think that's a differentiator
2018-11-06T02:35:52 < aandrew> well c1 is ac coupling the signal
2018-11-06T02:35:57 < jadew> the second one seems to be an inverting amplifier, but I'm not sure exactly why it's made like that
2018-11-06T02:35:59 < catphish> the incoming signal is ac coupled indeed
2018-11-06T02:36:06 < aandrew> then where I'd have expected it ot bias and be compared, it's not
2018-11-06T02:36:19 < catphish> this design may not be good :)
2018-11-06T02:36:38 < catphish> it *feels* overcomplicated at the end by 3 amplifiers
2018-11-06T02:36:47 < catphish> but i'm no expert here

2018-11-06T02:37:16 < BrainDamage> the 2nd opamp has the double effect of biasing the transistor and sucking up the current that would otherwise end in R8
2018-11-06T02:38:06 < BrainDamage> so it both biases and acts as a transconductance amplifier
2018-11-06T02:38:39 < jadew> BrainDamage, what is it biasing?
2018-11-06T02:39:17 < BrainDamage> the collector, the negative feedback loop keeps Vc constant even if the input varies
2018-11-06T02:40:09 < jadew> right
2018-11-06T02:40:19 < jadew> but why is it made like that?
2018-11-06T02:40:44 < catphish> i think i'm gonna set this up in falstad, i know what i have at R5 so i can model it from there
2018-11-06T02:40:58 < jadew> couldn't he have just fed the output from ic2a straight into the negative input of an inverting amplifier and gotten the same result?
2018-11-06T02:41:03 < BrainDamage> it's a rather odd design, maybe some of the opamp specs are barely matching like stability, etc

2018-11-06T02:41:31 < BrainDamage> hard to give a sure answer without delving in the datashit
2018-11-06T02:41:43 < BrainDamage> it does feel like an overcomplication
2018-11-06T02:42:09 < BrainDamage> a good quality opamp and 2 inverting amps, provided if stable, should be more than adequate
2018-11-06T02:42:58 < catphish> you get 2 opamps in that package, maybe using both was cheaper
2018-11-06T02:43:18 < jadew> I wonder if he's riding the non linear region of the transistor
2018-11-06T02:43:32 < jadew> could get a logarithmic effect out of it
2018-11-06T02:44:24 < jadew> although, 4k7 and 1k8 doesn't really sounds like it
2018-11-06T02:45:08 < jadew> yep, 1.38 V on the base, so not really
2018-11-06T02:53:15 < jadew> anyone found some good and cheap enclosures that don't look cheap? :D

2018-11-06T02:56:13 < jadew> I don't know
2018-11-06T02:56:45 < jadew> haven't seen a good yet that doesn't cost > $100
2018-11-06T02:57:10 < jadew> don't have links now, but it's those enclosures thare are made from multiple parts
2018-11-06T02:57:24 < jadew> chassis, metal sheet surrounding them, pro finish
2018-11-06T02:57:34 < jadew> nice looking front and back panels
2018-11-06T02:57:59 < catphish> just for fun i ran the antenna via a few metres of cable, didn't change anything
2018-11-06T02:58:23 < jadew> at 125 kHz, no doubt
2018-11-06T02:58:49 < catphish> so that's good, as long as i can figure out an amp setup, this should work
2018-11-06T03:02:25 < catphish> as far as i can see all it needs to do is turn any positive voltage from the ac coupled input into a logic 1

2018-11-06T03:09:45 < jadew> yeah, it might not work
2018-11-06T03:09:57 < catphish> well thats annoying
2018-11-06T03:10:12 < catphish> they may just have forgotten about people using their oauth
2018-11-06T03:10:20 < catphish> they're quite retarded
2018-11-06T03:10:30 < catphish> lol
2018-11-06T03:10:37 < jadew> it's ok, I don't really care, it's just that I got a message box from thunderbird
2018-11-06T03:18:54 < aandrew> dunno
2018-11-06T03:18:54 < aandrew> https://www.circuitlab.com/circuit/e8f3mf5e5hwu/rfidshit/
2018-11-06T03:19:01 < aandrew> if I connect the transistor up the sim explodes
2018-11-06T03:19:21 < aandrew> the first opamp is just integrating the envelope
2018-11-06T03:22:05 < catphish> i got as far as http://tinyurl.com/y7elpd47
2018-11-06T03:23:57 < catphish> i'm not really sure why i need more than that first step
2018-11-06T03:26:26 < aandrew> well the diode's the rectifier/envelope detector
2018-11-06T03:26:47 < aandrew> the first opamp drives low whenever the RF signal is higher, up when lower than some threshold
2018-11-06T03:27:03 < aandrew> the transistor would just act as a switch, but I can't quite get that to simulate
2018-11-06T03:31:07 < catphish> this works surprisingly well in a simulator http://tinyurl.com/ybr9rfgz
2018-11-06T03:31:17 < catphish> i imagine there's a reason it's not this simple in reality
2018-11-06T03:32:08 < catphish> it probably draws way too much current from the source for a start
2018-11-06T03:33:49 < catphish> right, and the incoming signal is ac coupled and offset to 2.5V

2018-11-06T03:35:13 < catphish> the voltage there probably isn't important, but i shoudn't put negative voltages into my amp really
2018-11-06T03:35:54 < catphish> the supply is 0-5v
2018-11-06T03:36:17 < catphish> anyway, this works in the simultor becuse there's an endless supply of current from that ac source
2018-11-06T03:37:31 < catphish> yes correct
2018-11-06T03:38:02 < catphish> and yes, falstad has an am source
2018-11-06T03:38:36 < catphish> oh yeah, it's not digital
2018-11-06T03:39:30 < catphish> well the output from the envelope detector looks like this: https://i.imgur.com/Ch9ulVV.jpg
2018-11-06T03:39:45 < catphish> square or sine wave, 6-8v
2018-11-06T03:40:21 < catphish> i simulated it with a 1v sine wave wth a 7v offset
2018-11-06T03:40:39 < catphish> but... the problem here is that this signal has inifnite current
2018-11-06T03:41:27 < catphish> aandrew made something better
2018-11-06T03:47:31 < catphish> aandrew seems to have modeled it with an opamp running at a few thousand volts homehow :(
2018-11-06T03:52:27 < catphish> he has provided a good way to simuate the coil output though, so i'll copy that

2018-11-06T04:06:43 < aandrew> no, it's the fucking sim doing the wrong thing with the transistor in circuit
2018-11-06T04:08:03 < aandrew> nice to know our sims are agreeing so far anyway
2018-11-06T04:08:24 < aandrew> the transistor is just an inverting switch
2018-11-06T04:08:47 < catphish> and this actually still appears to work: http://tinyurl.com/y9os9xky
2018-11-06T04:09:24 < aandrew> shouldn't that 70k be 270k?
2018-11-06T04:10:01 < catphish> i changed the value to what i actually built in my desk that gave the nicest looking envelope
2018-11-06T04:10:07 < aandrew> ah
2018-11-06T04:10:46 < catphish> but both will likely wotk
2018-11-06T04:11:12 < catphish> *work
2018-11-06T04:12:09 < catphish> the question is - what does the large circuit offer that mine lacks? less gain? or maye mine won't work with real life opamps
2018-11-06T04:12:44 < aandrew> I can't see why you can't feed the output of the first opamp directly into the PIC, *maybe* with an inverter 
2018-11-06T04:13:02 < aandrew> as far as I can tell the second opamp is used just because it's in the package
2018-11-06T04:13:08 < catphish> well that was my thought too

2018-11-06T04:25:50 < aandrew> the second is amplifying a digital siganl that's already at 5V

2018-11-06T11:49:00 < cjbaird> very goods. The stuff seems to have conductive adhesive..? (or stippled glue, or something) Either way, covering the bulk of the ribbon cable in Al, and using a strip of Cu for actual soldering into, gives something 0.000R from the shield to the GND
2018-11-06T11:49:00 < qyx> a poor-man bimetal
2018-11-06T11:50:03 < zyp> I bought a roll of aluminum tape a while ago to cover some holes in a metal enclosure
2018-11-06T11:50:11 < PeterM> nice, but why not jsut use shielded cable or some sort?
2018-11-06T11:50:17 < cjbaird> a poor-man RF shield .. The Al's slightly reduced conductivity isn't going to be an issue (..actually makes it better for the job)
2018-11-06T11:51:37 < PeterM> aluminium tape is good for that kinda thing, good for sealing the moisture sensitive bags too
2018-11-06T11:52:00 < cjbaird> Looked at FFC/FPC et.al for the past few days. Wantig 0.1" spacing-- FFC flat flex with that is unobtanium (or specialist supplier) now
2018-11-06T11:55:22 < cjbaird> The local 'nasty' radio club had all its copper plumbing in the building nicked not that long ago..
2018-11-06T11:56:04 < cjbaird> Gypsies, or Bogans.
2018-11-06T11:57:57 < cjbaird> A local Aluminium Smelter lost its copper power lines about a month ago-- that would've taken some serious organisation.
2018-11-06T11:58:34 < cjbaird> (about a kilometer of powerline, too)
2018-11-06T11:59:33 < qyx> here a decent amount of orangish optic conduit was stolen once
2018-11-06T12:00:00 < PeterM> how many contacts did you need on your ffc, because 1.25mm ffc is rpetty common, its not 1.25 but you're gonna need like 10 contacts before the difference is enough 
2018-11-06T12:01:48 < PeterM> it not 0.1"* sorry
2018-11-06T12:02:26 < karlp> cjbaird: there's a new hotel here currently laying big sheets of shiny copper on it's roof :)
2018-11-06T12:02:56 < karlp> seemed wonderfully cutesy and naiive given how that's treated in many other countries

2018-11-06T20:58:53 < aandrew> not a bad idea to use the water cooling though
2018-11-06T20:58:59 < sync> yes
2018-11-06T20:59:22 < con3> hmm... lcsc seems quite cheap
2018-11-06T21:12:13 < Steffanx> Even in pumps?
2018-11-06T21:12:37 < catphish> why can't all STM32s have roughly the same architecture / API? :(
2018-11-06T21:13:11 < Steffanx> It evolved.
2018-11-06T21:13:11 < catphish> i find it mad that they work in sich different ways
2018-11-06T21:13:40 < catphish> i started with the L4 and i love it, but then i look at the docs for things like F0 and it seems like a mess
2018-11-06T21:14:47 < catphish> i guess it's not dramatic, just mildly annoying that the same basic code won't run on the whole range
2018-11-06T21:16:09 < PaulFertser> Isn't that what HAL is supposed to help with? ;)
2018-11-06T21:17:30 < catphish> probably :)
2018-11-06T21:17:40 < catphish> i have but one more question
2018-11-06T21:18:21 < catphish> is there a trivial way to output a divided clock to a pin? or would i need to use a time + PWM?
2018-11-06T21:18:38 < catphish> *timer
2018-11-06T21:19:54 < catphish> i want to scale by 4mhz clock by 32 and dump a 125mhz clock out to a pin
2018-11-06T21:21:04 < Ultrasauce> look at clkout, but it has to be the system clock
2018-11-06T21:21:24 < Ultrasauce> and also won't produce good edges at 125mhz
2018-11-06T21:21:35 < catphish> yeah, just saw, probably too limited, i'll use a timer :)
2018-11-06T21:21:41 < malinus> catphish: just use the HAL/LL if you want the same API
2018-11-06T21:21:52 < catphish> malinus: yeah i guess you're right
2018-11-06T21:22:26 < Steffanx> 125mhz?
2018-11-06T21:22:34 < catphish> the more i use it, the more i move away from caring how it works and towards wanting to get things done
2018-11-06T21:22:38 < Steffanx> = kilohertz?
2018-11-06T21:22:40 < catphish> khz :)
2018-11-06T21:22:54 < Ultrasauce> oh yes definitely a timer then
2018-11-06T21:23:32 < catphish> i'll use a timer, just wondered if there was a simpler way to route sysclk -> divider -> gpio
2018-11-06T21:23:53 < Ultrasauce> that is the simple way

2018-11-06T22:33:42 < Ultrasauce> http://timecube.2enp.com/
2018-11-06T22:35:14 < Ultrasauce> When the Sun shines upon Earth, 2 – major Time points are created on opposite sides of Earth – known as Midday and Midnight. Where the 2 major Time forces join, synergy creates 2 new minor Time points we recognize as Sunup and Sundown. The 4-equidistant Time points can be considered as Time Square imprinted upon the circle of Earth. In a single rotation of the Earth sphere, each Time corner point rotates through the other 3-corner Time 
2018-11-06T22:35:14 < Ultrasauce> points, thus creating 16 corners, 96 hours and 4-simultaneous 24-hour Days within a single rotation of Earth – equated to a Higher Order of Life Time Cube.

2018-11-06T23:56:06 < malinus> BrainDamage: I think something wrong with your car if you have engine noise and vibration. Take it to a mechanic 
2018-11-06T23:57:12 < BrainDamage> malinus: both are negligible compared to the mechanical output
2018-11-06T23:57:48 < catphish> engline noise is quite fun, but electric motors aren't silent, they have different cool noises
2018-11-06T23:58:15 < BrainDamage> modulate the PWM / VFD to bad apple
2018-11-06T23:58:23 < catphish> :)
2018-11-06T23:58:34 < BrainDamage> make your car broadcast your weaboo status as you go
2018-11-06T23:58:35 < catphish> probably not as satisfying as dropping a couple of gears and hearing the engine go though
2018-11-06T23:58:48 < zyp> yeah, the HF whine when you're accelerating on a newly surfaced road is awesome
2018-11-06T23:58:59 < karlp> catphish: re, "implementing a software serial receiver is a lot harder than i imagined it to be" remember when I said, "are you trying to find a sw project?" :)
2018-11-06T23:59:09 < catphish> karlp: ha indeed
2018-11-06T23:59:14 < zyp> also, the instant accelerator response more than makes up for the lack of vibration and noise
2018-11-06T23:59:45 < catphish> zyp: i have instant accelerator response, just requires managing the turbo :)
2018-11-06T23:59:59 < zyp> you don't know what instant accelerator response is :p
--- Day changed Wed Nov 07 2018
2018-11-07T00:00:08 < catphish> i guess it's not instant if you have to plan for it
2018-11-07T00:00:56 < catphish> i dunno, i'd guess an ICE at 6000RPM will give you just as much response as electric, but i've never driven the latter so i can't say with certainty
2018-11-07T00:01:41 < kakimir> electric motor sound = mainly inverter fixed frequency whine
2018-11-07T00:01:53 < zyp> catphish, your whole wording illustrates the difference
2018-11-07T00:02:25 < catphish> zyp: one certainly requires more planning
2018-11-07T00:02:30 < zyp> electric motors doesn't need to be at a particular rpm to produce max torque
2018-11-07T00:02:49 < malinus> catphish: all the ICE response curves I've seen are laughable. No matter the RPM
2018-11-07T00:02:54 < catphish> zyp: that's really not true, that depends entirely on the motor and the control setup
2018-11-07T00:02:59 < zyp> kakimir, it's not fixed frequency at all
2018-11-07T00:03:06 < zyp> commutation frequency varies with speed, naturally
2018-11-07T00:03:16 < catphish> zyp: he means the PWM frequency
2018-11-07T00:03:38 < zyp> in my experience, it's the commutation frequency that's autible
2018-11-07T00:03:40 < catphish> there are 2 frequencies, the AC frequency, and the PWM frequency, both may be audible
2018-11-07T00:03:40 < zyp> audible
2018-11-07T00:03:58 < catphish> and the interaction between the two likely produces cool noises
2018-11-07T00:04:06 < emeb> Gah - writing & maintaining embedded software would be soooo much easier without the damned users.
2018-11-07T00:04:24 < catphish> zyp: perhaps if i ever build my EV i'll find out
2018-11-07T00:05:08 < emeb> I've got a UI that uses a rotary encoder with pushbutton to navigate a menu system. Now I've got users making suggestions for modifications to reduce the number of encoder clicks that they need to make for certain operations.
2018-11-07T00:05:35 < emeb> What they ignore is that reducing those clicks makes more clicks for other operations that are just as likely.
2018-11-07T00:05:36 < catphish> emeb: lol gotta hate users
2018-11-07T00:06:10 < emeb> this!

2018-11-07T00:08:38 < catphish> i've never understood ICE being unresponsive as being a problem, unless you drive automatic, it takes so little time (and is much fun) to set whatever torque you need with gears
2018-11-07T00:09:45 < zyp> the whole automatic/manual thing is also not something that matters for EVs, they all only have a single fixed reduction gear :p
2018-11-07T00:10:16 < catphish> indeed, with EV you can get pretty much constant torque until you start to run out of power
2018-11-07T00:10:36 < catphish> with that said, you'd still get *more* torque with gears :)
2018-11-07T00:11:58 < catphish> it's just not necessary, it's pretty sexy how much torque you can get out of a low speed motor
2018-11-07T00:12:58 < catphish> an induction motor at full current is just mad
2018-11-07T00:14:29 < zyp> I don't need more torque, already got enough to make the tires slip
2018-11-07T00:14:44 < catphish> karlp: recovering the bits seems so simple in theory, since *I* generate the clock, but it's not one bit per clock cycle, so one has to keep an eye on the offset that may randomly change
2018-11-07T00:15:44 < catphish> tires slipping is rather weather dependent :)
2018-11-07T00:16:03 < zyp> I mean on dry road
2018-11-07T00:16:22 < catphish> i can likely only do that in first gear
2018-11-07T00:16:33 < catphish> but that's enough :)
2018-11-07T00:16:57 < catphish> it costs me enough in tires
2018-11-07T00:17:01 < zyp> :p
2018-11-07T00:17:30 < zyp> I still haven't replaced them since I bought the car, but I guess I'll have to soon
2018-11-07T00:17:34 < catphish> from stationary, traction is by far the main factor in my golf's speed, needs 4wd really
2018-11-07T00:18:27 < catphish> if you want to, you can spin the wheels right through the first 2 gears, and i often do, it's far too much fun
2018-11-07T00:19:32 < zyp> how many km do one get out of a set of tires usually? I never thought much about that with the old car
2018-11-07T00:20:05 < englishman> 60k i guess

2018-11-07T00:20:27 < catphish> *30Mm
2018-11-07T00:20:39 < englishman> yeah but you probably drive like an englishman
2018-11-07T00:20:42 < zyp> I recently passed 60k in my car, but that's split between the summer set and the winter set
2018-11-07T00:21:05 < catphish> 2 years front tire replacement, just under 10,000 miles a year, that's 30Mm
2018-11-07T00:21:10 < catphish> do you guys use Mm?
2018-11-07T00:21:20 < catphish> or kkm?
2018-11-07T00:21:27 < Steffanx> Km
2018-11-07T00:21:47 < catphish> i think Mm is a much cooler unit
2018-11-07T00:21:57 < zyp> as a pedant, Mm makes sense, but everybody leaves out the km unit and then speak of k (km)
2018-11-07T00:22:20 < catphish> oh i see, so just 20k
2018-11-07T00:22:29 < catphish> we do the same (with miles)
2018-11-07T00:22:55 < zyp> so, by «passed 60k» I technically meant «passed 60 Mm»
2018-11-07T00:23:04 < Steffanx> I would say 20 thousand km
2018-11-07T00:23:11 < Steffanx> Like any dutchy.
2018-11-07T00:23:23 < englishman> thats like a new set of tires every year
2018-11-07T00:23:27 < zyp> how do you say thousand in dutch?

2018-11-07T00:27:32 < zyp> yeah, the articles google found me seems to agree with that
2018-11-07T00:28:40 < zyp> I'm not sure how many km I put on each of the sets, but on average they're both on 30k now
2018-11-07T00:28:52 < zyp> so at least one got more :p
2018-11-07T00:29:16 < zyp> I'm guessing the summer set gets used a bit more
2018-11-07T00:29:38 < englishman> looks like they use ugfx
2018-11-07T00:29:38 < catphish> i guess i'll start by detecting a level change, then measure the time between each subsequent change, maybe i don't need anything too much more complicated than that
2018-11-07T00:29:53 < zyp> just use input capture?

2018-11-07T00:30:23 < catphish> zyp: i'm hoping i can do it in software because ultimately i want to capture ten at once
2018-11-07T00:31:17 < zyp> ten timer channels isn't really a big deal
2018-11-07T00:31:35 < zyp> a typical stm32 can easily do twice that

2018-11-07T00:31:59 < catphish> really? i thought each timer could do about 2
2018-11-07T00:32:23 < zyp> the standard timers have four channels each
2018-11-07T00:33:20 < zyp> and then there's some reduced set ones with two channels, but I don't use them much
2018-11-07T00:34:49 < catphish> oh yeah, 4 channels on this timer i'm using
2018-11-07T00:34:54 < englishman> dongs: Looks like your old F3 and F4 flight controllers are going to be going extinct like the dodo.
2018-11-07T00:35:48 < catphish> my first ever project was a flight controller, wish i had stm32 back then :(
2018-11-07T00:36:13 < catphish> doing it in 8 bit avr sucked
2018-11-07T00:36:16 < englishman> all teh current hobby flight controllers are ported from an old 328p project
2018-11-07T00:36:22 < englishman> and not much has changed except better timers

2018-11-07T00:37:12 < zyp> catphish, a flight controller is what got me started on stm32
2018-11-07T00:37:28 < zyp> like eight years ago
2018-11-07T00:37:39 < catphish> mine would probably have worked better if i had known about stm32 :)
2018-11-07T00:38:10 < catphish> worked though
2018-11-07T00:38:37 < catphish> zyp: you managed to get something to fly?
2018-11-07T00:38:51 < zyp> for some definition of «fly», sure

2018-11-07T00:44:24 < zyp> https://bin.jvnv.net/file/BOS5D.mp4 <- I think I was live-tuning feedback gains here
2018-11-07T00:44:25 < catphish> it was really hacky though, literally an arduino mega with modules connected with wires :)
2018-11-07T00:44:58 < zyp> hehe, my first iteration was a leaflabs maple with a protoshield
2018-11-07T00:45:18 < zyp> and that was the only iteration that has actually been flying, the newer board I made has only been tested tethered
2018-11-07T00:45:54 < catphish> i did something simular, one axis at a time https://www.youtube.com/watch?v=QOXN2BqeQmI
2018-11-07T00:46:07 < zyp> https://bin.jvnv.net/file/POIDL.mp4 <- feedback stuff that works a bit better

2018-11-07T00:48:03 < catphish> better than mine
2018-11-07T00:48:23 < catphish> but then, i was a bit more reckless, just went ahead and flew mine
2018-11-07T00:48:37 < zyp> https://bin.jvnv.net/file/ZGHgY.jpg <- similar test setup
2018-11-07T00:48:41 < zyp> https://bin.jvnv.net/file/gYu61.jpg <- ended up like this
2018-11-07T00:48:52 < catphish> haha
2018-11-07T00:49:19 < zyp> oh, and before that
2018-11-07T00:49:24 < zyp> https://bin.jvnv.net/file/uhket.jpg <- I tied it to a box
2018-11-07T00:49:32 < zyp> worked well until it flipped over the box
2018-11-07T00:50:02 < catphish> i learned a lot, but had to rely heavily on my mpu6050 as the avr and/or my maths wasnt good enough to do the combined integration stuff for leveling
2018-11-07T00:50:23 < catphish> haha
2018-11-07T00:50:33 < zyp> after the hanging accident, I tied it to a set of pipes, to make it harder to flip: https://bin.jvnv.net/file/J7cZJ.jpg

2018-11-07T00:51:34 < zyp> that worked well enough that I took it out and flew it with the pipes :p
2018-11-07T00:51:55 < zyp> then I took off the pipes and it still kept stable enough

2018-11-07T00:52:22 < zyp> but I mostly only had throttle control, not pitch/roll/yaw, so I could control how high it went, not where it went :p

2018-11-07T01:22:52 < karlp> (i had made anote of glsegei's wild chopstix project, just wanted to cover a few more)
2018-11-07T01:23:54 < zyp> heh
2018-11-07T01:25:24 < zyp> do people actually use it?
2018-11-07T01:25:47 < englishman> any interview tips from successful job-havers
2018-11-07T01:25:51 < englishman> should i bring some shit that i made
2018-11-07T01:25:58 < zyp> drop laptop on floor
2018-11-07T01:26:15 < zyp> I tried that once, got the job
2018-11-07T01:26:35 < englishman> will do
2018-11-07T01:26:37 < englishman> was it a mac
2018-11-07T01:26:46 < zyp> yeah: https://bin.jvnv.net/file/o3UXi.jpg
2018-11-07T01:27:04 < karlp> zyp: no idea. I saw it used as a submodule in another project that someone linked to, also from this glsergei duder
2018-11-07T01:27:18 < kakimir> I wonder what the heck I was doing involving sense lines drawn to shunt footprint
2018-11-07T01:27:35 < karlp> but glsergei had usb impls submitted to chopstx from other people to handle other architecutres, so at least 3-4 people?
2018-11-07T01:27:50 < karlp> englishman: why are you interviewing for ajobn?
2018-11-07T01:27:55 < englishman> to get a job
2018-11-07T01:28:08 < karlp> aren't you a successful succes story as a true canandian small business operator?
2018-11-07T01:28:09 < Ultrasauce> gonna be a scab for canada post?
2018-11-07T01:28:30 < englishman> yeah but its boring
2018-11-07T01:28:32 < englishman> super boring
2018-11-07T01:28:47 < englishman> i'd rather make less money and do something cool
2018-11-07T01:29:02 < zyp> if you're gonna get a job instead, can I have your P&P stuff?
2018-11-07T01:29:05 < karlp> so, just so I understand, youð're going to pack it all in entirely and go back to working full time?
2018-11-07T01:29:11 < karlp> or are you just looking for some part time stuff?
2018-11-07T01:29:13 < karlp> or what?
2018-11-07T01:29:38 < englishman> sure zyp but transport will probably cost more than it's worth
2018-11-07T01:29:41 < englishman> full time
2018-11-07T01:30:02 < karlp> I mean, I wasunder the impression that the "great uplandistand quebec or something" was maybe not scratching your design loves, but was still positive cash and viable
2018-11-07T01:30:25 < englishman> sure is
2018-11-07T01:30:33 < englishman> in fact last month was crazy money
2018-11-07T01:30:36 < karlp> so it must reallllly be killing your soul to just kill a profitvable business instead of taking on a minion to hold it running while you play with things for yourself
2018-11-07T01:31:01 < karlp> I mena, I get it, kinda, but how did you get so far down the road of running that business if you weren't at all interested in running your own business?

2018-11-07T01:31:54 < englishman> well, the lease is up next year too, which means find a new place and move everything, and pay tons more money in rent, or buy a place / build something and actually have to pay bills for next ~decade and commit myself to it
2018-11-07T01:32:10 < englishman> dealing with customers is fine
2018-11-07T01:32:45 < karlp> oh, I thought you were doing it all out of your shed on your farm
2018-11-07T01:33:45 < englishman> no i've had an office in the city for about 2.5 years
2018-11-07T01:34:26 < englishman> i would like to build a 200 m^2 shed on the farm tho
2018-11-07T01:34:28 < englishman> and move things there

2018-11-07T01:35:50 < karlp> I got no advice on interviews, I moved to iceland where nepotism is the only thing that mattere
2018-11-07T01:36:21 < zyp> same shit here
2018-11-07T01:36:31 < karlp> and I demonstrated a sufficient modicum of skill a few years ago, so unless I have a serious meltdown or something I'm ~fine
2018-11-07T01:37:08 < zyp> I've never gotten a job I've just applied for, every single job I've had I've gotten through connections
2018-11-07T01:37:25 < karlp> hrm.
2018-11-07T01:37:36 < karlp> I think I've applied for two jobs that I didn't get.
2018-11-07T01:38:07 < englishman> if i dont get a job by spring i will have to build somewhere to put all my shit
2018-11-07T01:38:20 < englishman> if i do, then i can move on
2018-11-07T01:38:22 < zyp> first job I got out of uni was because one of the guys working there were also working part time at the uni as a programming professor
2018-11-07T01:38:24 < karlp> at least you have a nice runway then
2018-11-07T01:38:32 < englishman> zyp, same
2018-11-07T01:38:48 < englishman> i casually put out the CV a few times but this interview is thru a mutual friend
2018-11-07T01:38:53 < zyp> and all jobs I've got since then have been through former coworkers
2018-11-07T01:39:07 < karlp> my first job out of uni was because some director at cisco went to my uni, and they were still desparate for any engineers they could hire.
2018-11-07T01:39:21 < sync> englishman: or you build anyway and have a fallback plan
2018-11-07T01:39:31 < karlp> moving to iceland was a bit of a "right, so... don't know anyone, here's my cv" but it worked well enough
2018-11-07T01:39:47 < karlp> subsequent jobs have been the "it's not what you know, it's who you know" for better and wrose
2018-11-07T01:40:30 < zyp> the job I have now is because my old boss got asked if he knew somebody and recommended me
2018-11-07T01:40:41 < englishman> sync: the hugegarage idea works for that
2018-11-07T01:40:52 < zyp> the job I had before that was because one of my former coworkers ended up there and they wanted more people
2018-11-07T01:40:53 < englishman> even if i quit and get a realjob, i just end up with a big garage
2018-11-07T01:41:51 < Steffanx> Just hire someone to do it all for you. And get yourself that ceo ferrari

2018-11-07T01:42:11 < karlp> we had a restaraunt open down the street a few months ago
2018-11-07T01:42:17 < karlp> closed again within 6 weeks
2018-11-07T01:42:40 < karlp> apparently the "owner" thought that all the money in the accoutn was money they coul djust spend on things
2018-11-07T01:42:54 < zyp> I hope the stuff my current company develops end up working out, not looking forward to look for a job again if the company runs out of money :p
2018-11-07T01:43:33 < englishman> i could pay you in cat treats
2018-11-07T01:43:45 < zyp> on the other hand, I'm the only actual programmer, so my job is very safe as long as they can afford to keep the lights on at all
2018-11-07T01:44:45 < zyp> maybe next time I'm looking for a job, I can get one at the company where all my uni friends work :p
2018-11-07T01:45:10 < zyp> somehow most of them have ended up in the same company
2018-11-07T01:45:52 < zyp> hmm
2018-11-07T01:46:54 < zyp> I actually talked to that company a couple of years ago, but I didn't feel the position they were looking to fill at the time sounded very interesting, and only one of my friends worked there already
2018-11-07T01:47:01 < karlp> one day, there will be a hashhashstm64 nordic conspiracy, ruling the world and shit....
2018-11-07T01:47:19 < zyp> in retrospect, that might have been a bad decision, they seem to do quite a bit of fun stuff nowadays
2018-11-07T01:47:36 < zyp> not embedded though, so idk if I would like it anyway, but eh
2018-11-07T01:48:26 < karlp> eh, fun is where you find it.

2018-11-07T01:48:54 < zyp> yeah
2018-11-07T01:48:59 < karlp> not that I do it "professionally" I don't do all that much on the side
2018-11-07T01:49:07 < BrainDamage> we can even assign the tasks based on each one's best skills
2018-11-07T01:49:15 < BrainDamage> eg loranceb can do the DB management
2018-11-07T01:49:20  * karlp laughs
2018-11-07T01:49:29 < zyp> I've done some pcb layout contract work on the side earlier this year
2018-11-07T01:50:04 < englishman> that feels like what im doing now
2018-11-07T01:50:07 < englishman> over and over again
2018-11-07T01:50:15 < zyp> layout?
2018-11-07T01:50:19 < englishman> and assy
2018-11-07T01:50:21 < englishman> but like
2018-11-07T01:50:24 < englishman> it all feels like side work
2018-11-07T01:50:32 < englishman> that i can't refuse due to dollar signs
2018-11-07T01:50:41 < zyp> hehe
2018-11-07T01:51:14 < Ultrasauce> sounds like you need to find a company to have a tighter / more regular b2b relationship with
2018-11-07T01:51:33 < englishman> i did, the PCB fab down the road
2018-11-07T01:51:39 < englishman> they send me almost all of their assy work
2018-11-07T01:51:52 < englishman> and all the design work
2018-11-07T01:52:22 < englishman> in fact they laid off their assembly manager guy because he wasn't doing anything except emailing me
2018-11-07T01:52:22 < karlp> again, this just makes me ask why you even started that parth
2018-11-07T01:52:31 < karlp> it seems lik eyou reallllly don'ðt want to be doing it
2018-11-07T01:53:12 < englishman> once upon a time i had some stuff i made that i wanted to sell
2018-11-07T01:53:20 < englishman> employees even
2018-11-07T01:53:36 < englishman> after that ended due to me being an idiot and totally missing what the market was about, it was just me and a dicknplace

2018-11-07T01:54:18 < zyp> I've found that the schematic part of pcb design is kinda boring since it involves a bunch of part selection bullshit, but once the schematic is done, working out the layout puzzle is a fun challenge
2018-11-07T01:54:28 < englishman> then i got a big design and assy contract thru an irc'er so i didnt have to look for a realjob
2018-11-07T01:54:56 < zyp> apparently other people thinks the layout part is tedious, so I'm happy to do only that part for them :)
2018-11-07T01:54:57 < englishman> and the contracts keep coming

2018-11-07T01:56:32 < jadew> couldn't you sell it for less?
2018-11-07T01:56:47 < zyp> couldn't you give it away for free?

2018-11-07T05:02:54 < Brittany> I'm having a slight DMA transfer problem. I'm finding that CPU activity is able to interrupt the timer based LED data. I use timer events which drive the data to GPIO pins. The issue I see is an intermittent 'flicker' where if I set one bit, the next bit may occasionally be set. (I.e. I send a 0b00001000, and I get a 0b00010000), does anyone know how to explain the issue I'm facing?
2018-11-07T05:03:30 < Brittany> excuse the terrible question formatting. 3am here.
2018-11-07T05:05:48 < dongs> no beacuse youre not explaining what the fuck you're trying to do. DMA is DMA, touching GPIO from timer is not DMA
2018-11-07T05:07:04 < aandrew> Brittany: without any real data or code to look at, it sounds like your timer requires CPU intervention to tell it what the next interval is and it's not getting that data in time
2018-11-07T05:07:52 < aandrew> generally you either use a timer to DMA data from memory to a GPIO pin, or you DMA data (timer periods) to a timer 
2018-11-07T05:08:14 < aandrew> sounds like you are using WS2812 type devices and trying to drive them in a background task

2018-11-07T05:09:11 < Brittany_> @dongs apologies. i'm tired, tried to be concise and just ended up writing a shitty question. excuse me
2018-11-07T05:10:03 < Brittany_> @aandrew you are right. i literally just figured it out after wrestling with it for a few hours. I was never re-initializing my timer's counter. So it seems that some CPU activity was taking precedence over the DMA transfer complete turning off my timer.
2018-11-07T05:10:15 < Brittany_> I solved this by re-intialization of the timer in the start up routine.

2018-11-07T05:11:58 < Ultrasauce> the rubber duck is real
2018-11-07T05:14:17 < Brittany_> I realized as I wrote the question. I thought that if I was sending 0b00001000 through my gpio pins by timer, that I was getting 0b00011000 out. so i probed it before asking and found it to be 0b00010000.
2018-11-07T05:14:47 < Brittany_> when i thought it was 0b00011000, I assumed it was because the DMA 'lagged' and kept the output high for too long.
2018-11-07T05:16:01 < Ultrasauce> it's worth mentioning that even though dma leaves the cpu 'free' they still have to use the same buses to communicate with peripherals
2018-11-07T05:17:44 < Brittany_> I'd say I'm quite new to this. I've had about 3 months experience. It's interesting learning all this but it's quite scary working at such a low level, since there's so much under the hood I'm perplexed by.

2018-11-07T14:31:26 < karlp> outlook / office365 web interface started offering me the option of unsubscribing from individual senders this morning :)
2018-11-07T14:31:28 < catphish> i never found a good way to count times between transitions of lots of pins, one timer can really only count one thing, i'm now thinking the best option is probably a single free running timer, and and EXTI for each pin, it can just read the timer value when it fires
2018-11-07T14:31:28 < mawk> so you can multiply that by 10 or 100 and get the maximum safe dose
2018-11-07T14:31:50 < karlp> just a special footer on all my mai now, "getting too much mail from <yourboss@workdomain.com> ? unsubscribe here!"
2018-11-07T14:31:56 < mawk> you can read a whole bank at once catphish 
2018-11-07T14:33:14 < catphish> mawk: the problem is that i have 10 pins (doesn't matter which) and i want to know how long between transitions on each pin, but they're not synchronized in any way with eachother
2018-11-07T14:33:27 < mawk> ah
2018-11-07T14:33:37 < catphish> so i'd like to know when pin1 changes, what its new state is, and how long it was in the old state
2018-11-07T14:33:43 < mawk> I see
2018-11-07T14:34:27 < mawk> one timer with the smallest countdown possible, you read the banks, xor with the last value to get which changed, process that
2018-11-07T14:34:33 < mawk> adjust the countdown value for the maximum processing time
2018-11-07T14:34:39 < jadew> karlp, that's neat, but it's better to mark them as spam if it's indeed spam you didn't subscribe to
2018-11-07T14:35:26 < catphish> mawk: my current approach is pretty much what you just said, my main loop constantly xors the port with its previous value, when a port changes, it records the timestamp from a freerunning timer
2018-11-07T14:35:48 < Steffanx> Den Hague. Lol mawk. The quality spam
2018-11-07T14:36:06 < mawk> that's where I went the last time with that bus company
2018-11-07T14:36:13 < mawk> so they want me to go again
2018-11-07T14:36:52 < Steffanx> The Hague or Ded Haag. Not Den Hague ;)
2018-11-07T14:36:52 < catphish> yeah i think i'll continue with this approach then, a freerunning timer with a 32 bit counter and then another timer that polls the port periodically
2018-11-07T14:37:03 < Steffanx> Ded = den
2018-11-07T14:37:40 < catphish> Cracki: that's the second option, which may be better
2018-11-07T14:37:54 < mawk> den haye
2018-11-07T14:37:56 < catphish> in fact almost certainly is better :)
2018-11-07T14:38:08 < karlp> jadew: sure, but I'm saying this is something it's adding to _every_ email footer, even from colleagues :)
2018-11-07T14:38:11 < catphish> free running timer + 10 separtate EXTI
2018-11-07T14:38:28 < jadew> karlp, yeah, it's a great feature IMO :)
2018-11-07T14:38:33 < catphish> nah, EXTI is pin-specific
2018-11-07T14:38:53 < karlp> go check your irq table boi
2018-11-07T14:39:04 < karlp> you don't get 10 separate extis.
2018-11-07T14:39:04 < mawk> one ISR per pink bank 
2018-11-07T14:39:12 < mawk> pin
2018-11-07T14:39:22 < catphish> oh really, i thought it was one interrupt per PIN
2018-11-07T14:39:30 < catphish> Cracki: that can be
2018-11-07T14:39:36 < catphish> *they can be
2018-11-07T14:41:19 < catphish> that was my thinking, each pin has its own ISR, it calls a pin-change function with the pin number
2018-11-07T14:41:33 < catphish> unfortunately it doesn't know if the transition was rising or falling
2018-11-07T14:41:59 < mawk> in the relevant EXTI ISR you can read the whole bank at once
2018-11-07T14:42:07 < mawk> and quickly xor that with the previous bank value
2018-11-07T14:42:10 < mawk> and call the relevant subroutines
2018-11-07T14:42:35 < karlp> ffs, stop speculating this bullshit and go check the RM
2018-11-07T14:42:54 < catphish> so yeah, have to read the bank regardless, this detail is not critical
2018-11-07T14:42:59 < karlp> you can set rising or falling, and toggle which edge you want to look for in the irq even.
2018-11-07T14:43:31 < catphish> karlp: actually i want both, just i just realised, i can only watch for the one i'm expecting next!
2018-11-07T14:44:19 < karlp> edges dummy,
2018-11-07T14:44:31 < catphish> yes, i mean which edge on a particular pin i'm expecting next
2018-11-07T14:45:02 < catphish> so i just start by assuming all pins are low and monitor for a rising edge, when i get one i assume it's high and monitor for a falling edge
2018-11-07T14:45:35 < catphish> not if an interrupt was missed because of noise
2018-11-07T14:45:47 < catphish> the signal occasionally bounces
2018-11-07T14:46:17 < catphish> if it changes too fast i will just ignore it, and wait for the next expected change
2018-11-07T14:46:48 < catphish> perhaps
2018-11-07T14:47:07 < mawk> if it's alternating and you miss one and you never read the real value that may go wrong somewhere I'm sure
2018-11-07T14:47:11 < catphish> anyway, it seems that this approach will definitely work, combines with a 32 bit free running timer
2018-11-07T14:47:24 < mawk> you'll need to miss another one to get right again
2018-11-07T14:48:06 < catphish> 125khz modulation, bits are 32 high + 32 low
2018-11-07T14:48:24 < catphish> so time between edges is... 128uS
2018-11-07T14:49:18 < catphish> each bit is formed of 32 clock cycles high followed by 32 clock cycles low, or vice versa
2018-11-07T14:50:34 < catphish> so 2 bits, a zero followed by a 1, would be 32*4us low, 32*4us high, 32*4us high, 32*4us low
2018-11-07T14:51:57 < catphish> when i see it stay high for 64 consecutive cycles then fall, i know i'm now half way through a binary one, and i can then track onward from there
2018-11-07T14:53:37 < catphish> so the information i need in order to know what bit i am receiving is: 1) what is the transition 2) what was the period from the last transition 3) what was the last known bit. (3) is not required in the special case where i see a 64-cycle period, because at that point the current bit can be determined directly
2018-11-07T14:54:07 < catphish> i believe this is standard manchester encoding
2018-11-07T14:56:27 < catphish> this makes me wonder if a quick search for manchester encoding algorithm would yield other good ways to do this :)
2018-11-07T15:03:48 < emeryth> catphish: how about DMAing the gpio port state into a large buffer and analyzing it later?
2018-11-07T15:05:45 < catphish> emeryth: that's not such a silly idea either
2018-11-07T15:06:01 < mawk> but you don't have time to analyze latre
2018-11-07T15:06:10 < mawk> you have to register constantly
2018-11-07T15:06:32 < catphish> i suspect the code will be more efficient doing it on the fly with interrupts
2018-11-07T15:07:11 < mawk> at the limit with a very large buffer, the DMA method looks more efficient; you do all the processing at once
2018-11-07T15:07:13 < catphish> an EXTI instantly gives me most of the needed information, just need to to a quick calculation on the current position of the change in the freerunning timer
2018-11-07T15:08:05 < emeryth> mawk: double buffering, you analyze one buffer while capturing in the other
2018-11-07T15:08:25 < catphish> the problem is that sampling 10 things at at 125khz doesn't give me many clock cycles to do the processing!
2018-11-07T15:08:30 < mawk> ah
2018-11-07T15:08:33 < mawk> yeah that seems nice then
2018-11-07T15:09:02 < mawk> with DMA you have all the processing time you want, catphish 
2018-11-07T15:09:05 < mawk> the processor time, at least
2018-11-07T15:10:04 < catphish> at 80MHz that's 1.25 million samples per second, only 64 cycles to process each one, i'm sure it's possible, but i don't see the need
2018-11-07T15:10:25 < mawk> you can sample many bits
2018-11-07T15:10:34 < mawk> and increase the processing time that way
2018-11-07T15:11:10 < catphish> i guess i can process all 10 samples in a single instruction if none have changed :)
2018-11-07T15:11:25 < catphish> still i see no benefit over just firing an interrupt when it changes
2018-11-07T15:11:42 < catphish> all the other code would ultimately just lead to that anyway
2018-11-07T15:12:35 < mawk> the benefit is that the processor is hands free during the DMA capture
2018-11-07T15:12:46 < mawk> you have virtually no halt time for the capture
2018-11-07T15:16:08 < catphish> yeah i see, with a double buffer it could be efficient to batch process while the next batch is capturing
2018-11-07T15:16:49 < catphish> with that said, i still like the EXTI+freerunning timer thing
2018-11-07T15:17:00 < catphish> with selective edge detection
2018-11-07T15:22:23 < mawk> yeah
2018-11-07T15:22:29 < mawk> if you can work out the problem with missed edges
2018-11-07T15:23:08 < catphish> well hopefully there won't be any
2018-11-07T15:23:23 < catphish> i assume STM32's edge detection doesn't randomly fail to detect edges
2018-11-07T15:24:02 < mawk> or if the edge bounce fast enough
2018-11-07T15:24:26 < catphish> mawk: if the edge bounces fast, i quite deliberately want to ignore all but the first transition
2018-11-07T15:24:36 < catphish> so that's all good
2018-11-07T15:25:11 < catphish> envelope-detected EM4100
2018-11-07T15:25:39 < catphish> EM4100: https://i.imgur.com/ETJvOsa.jpg - my signal: https://i.imgur.com/7ut7glo.jpg
2018-11-07T15:25:44 < catphish> Haohmaru: yes
2018-11-07T15:27:26 < karlp> noone cares about your pic12f garbage
2018-11-07T15:27:32 < catphish> Haohmaru: i want to poll 10 of them :)
2018-11-07T15:27:39 < catphish> and yes, oversampling would be good
2018-11-07T15:29:20 < karlp> ncie to see these smaller L4 parts coming out, might actually be viable upgrade/replacements for l1 one day
2018-11-07T15:30:39 < karlp> jadew: wrt that capacitance layer inthe stackup we were talking about the other week, digikey just mailed me about it:

2018-11-07T15:30:43 < karlp> zdVTyJ9
2018-11-07T15:30:45 < karlp> gah, stupid link
2018-11-07T15:31:07 < catphish> another option here is to detect a single edge and then just blindly assume the data that follows is clocked accordingly
2018-11-07T15:32:03 < catphish> so detect one edge, wait 16 cycles, then just read one sample every 32 cycles for a while, which should be right on the middle of the period between transitions

2018-11-07T16:24:41 < Steffanx> Welcome sir
2018-11-07T16:24:43 < sk_tandt> Where may I find an intro to STM32 programming?
2018-11-07T16:24:49 < kakimir> hello sir
2018-11-07T16:25:04 < sk_tandt> I've seen the demo code from ST, but it's much too structured to show a basic approach to it
2018-11-07T16:25:32 < kakimir> you want really low level flavour to it?
2018-11-07T16:25:56 < sk_tandt> Would you recommend it? : P
2018-11-07T16:25:58 < kakimir> or do you like more IDE and wizards?
2018-11-07T16:26:11 < sk_tandt> Ideally I'd like to learn both
2018-11-07T16:26:13 < kakimir> sk_tandt: do you use vim?
2018-11-07T16:26:26 < sk_tandt> kakimir: yep, but I still go with nano most of the time

2018-11-07T16:29:13 < aandrew> thorn gets it
2018-11-07T16:29:18 < Thorn> you can use quality russian software called clion
2018-11-07T16:29:24 < Thorn> but it's bloated and costs $$$
2018-11-07T16:30:12 < karlp> since when is jetbrains russian?
2018-11-07T16:30:18 < Thorn> since day 1
2018-11-07T16:30:21 < karlp> wat
2018-11-07T16:30:51 < karlp> always thought it was czech originally
2018-11-07T16:31:05 < mawk> clion only does with cmake Thorn no ?
2018-11-07T16:31:17 < mawk> I tried for some minutes to set it up with plain make and dropped that
2018-11-07T16:31:18 < sk_tandt> Jokes aside, I -can- reverse engineer the ST code, but will only teach me how to -run- that thing, not how to build its code

2018-11-07T16:53:57 < kakimir> 3 down pulses
2018-11-07T17:09:24 < Thorn> 3 down pulses up
2018-11-07T17:21:15 < zyp> didn't the xmegas come first?
2018-11-07T17:21:37 < Rickta59> those pdi attinys are very cheap even in qty 1
2018-11-07T17:21:45 < Rickta59> seem pretty capable
2018-11-07T17:22:21 < Rickta59> the thing that makes them palatable is the unified memory space
2018-11-07T17:22:46 < Rickta59> might give the stm8 things a run for their money
2018-11-07T17:24:40 < Rickta59> you can access ram and flash in the same manner
2018-11-07T17:25:06 < Rickta59> st ld .. not lpm stuff
2018-11-07T17:25:39 < Rickta59> so arm people might get interested in them
2018-11-07T17:26:17 < Rickta59> most annoy thing about the avrs was having to do the goofy PROGMEM thing
2018-11-07T17:26:19 < zyp> unified memory spaces are easier to work with
2018-11-07T17:26:35 < zyp> exactly
2018-11-07T17:27:06 < zyp> does it matter if you call it PROGMEM or __flash?
2018-11-07T17:27:06 < Rickta59> not really .. you have to use different functions to read and write it
2018-11-07T17:28:40 < Rickta59> i'm talking about data in the flash that can be accessed from code directly
2018-11-07T17:28:47 < zyp> Cracki, how does that work when a function take a pointer as an argument?
2018-11-07T17:29:21 < Rickta59> well in the unified memory model pointers to code and pointers to data are the same thing
2018-11-07T17:29:41 < zyp> ah, right, so it's part of the pointer type
2018-11-07T17:29:54 < Rickta59> so const char foo[] = "asdfasdf" .. just works
2018-11-07T17:30:02 < Rickta59> goes into flash and can be accessed like ram
2018-11-07T17:30:04 < zyp> so you'd have to do void foo(uint8_t __flash *p) or something
2018-11-07T17:30:14 < zyp> makes sense
2018-11-07T17:30:21 < zyp> still annoying
2018-11-07T17:30:37 < Rickta59> try creating and array of const pointers to arrays
2018-11-07T17:30:43 < Rickta59> it becomes very annoyting
2018-11-07T17:31:05 < Rickta59> anyway all that is gone in those new avr tinys
2018-11-07T17:31:49 < zyp> progmem is just a section attribute
2018-11-07T17:32:25 < zyp> haha
2018-11-07T17:34:06 < zyp> haha
2018-11-07T17:34:18 < emeb> snerk
2018-11-07T17:34:34 < zyp> why even bother with 16-bit realmode?
2018-11-07T17:35:09 < zyp> yeah
2018-11-07T17:35:23 < zyp> also with EFI I believe even the bootloader starts in protected/long mode

2018-11-07T18:21:09 < jadew> it's not very expensive
2018-11-07T18:24:05 < karlp> well, it's still got to get into your layer stuck, but yeah

2018-11-07T18:31:06 < jadew> karlp, looks like it has a dielectric constant of 21 (if my math is right), that's 5 times higher than FR-4
2018-11-07T18:31:31 < bitmask> 8 ohms per meter, lets heat this baby up
2018-11-07T18:32:06 < jadew> ah, they provide it in the datasheet, they say it's 22
2018-11-07T18:32:28 < karlp> they have a few versions.
2018-11-07T18:32:55 < jadew> I think only the thickness varies

2018-11-07T20:46:32 < ds2> probally no more then 50mA 
2018-11-07T20:47:27 < ds2> think some watches use it also for the backlight (I think)
2018-11-07T20:47:36 < ds2> figuring LEDs...
2018-11-07T20:47:55 < kakimir> hmm
2018-11-07T20:48:11 < ds2> what do you need it for?
2018-11-07T20:48:17 < qyx> kaki going cheap
2018-11-07T20:48:34 < kakimir> I have power board and controller board
2018-11-07T20:48:42 < kakimir> both smaller than a dime
2018-11-07T20:49:02 < ds2> how many wires do you have?
2018-11-07T20:50:28 < kakimir> 7-10
2018-11-07T20:50:41 < ds2> do you need them to be removeable?
2018-11-07T20:50:48 < kakimir> no
2018-11-07T20:51:16 < ds2> then why not just solder rigid wires?
2018-11-07T20:51:32 < ds2> or use a 1/8w throughhole 0ohm resistor
2018-11-07T20:51:55 < kakimir> boards are 18mm diameter
2018-11-07T20:52:13 < ds2> and the problem is?
2018-11-07T20:52:22 < englishman> rigidflex
2018-11-07T20:52:25 < englishman> is the answer
2018-11-07T20:52:57 < kakimir> if I have it covered with THT holes - where do I put all the electronics? ds2 
2018-11-07T20:53:34 < ds2> 1/8W resistors aren't that big
2018-11-07T20:54:05 < ds2> 1.8mm 
2018-11-07T20:54:35 < kakimir> also no THT allowed to another board because conductive materials behind it
2018-11-07T20:54:36 < ds2> or if you can have the buldge, just use the leads
2018-11-07T20:55:02 < kakimir> conductive materials like a contact
2018-11-07T20:55:19 < ds2> if holes are a problem, put pads on the boards. then make the leads into U's solder that to the pads

2018-11-07T22:08:46 < catphish> oh good :)
2018-11-07T22:08:50 < zyp> read the section on timer linking
2018-11-07T22:09:16 < catphish> the work linking doesn't appear in my manual

2018-11-07T22:10:09 < catphish> "Using one timer as prescaler for another timer"
2018-11-07T22:10:15 < jpa-> however, you need to do the "read twice" trick if you want to read the values from both linked timers synchronously

2018-11-07T23:24:40 < Steffanx> heh, little progress is still progress zyp :D
2018-11-07T23:25:07 < zyp> what do you mean little progress? :p
2018-11-07T23:25:52 < zyp> I got all the counter bases adjusted and lined up
2018-11-07T23:29:19 < zyp> I don't think I wanna do the trim until I've checked the fit with the countertops
2018-11-07T23:29:25 < zyp> and they don't arrive until monday
2018-11-07T23:29:32 < catphish> ah balls, on this chip EXTI 0-4 have their own ISR, the rest are shared :(
2018-11-07T23:29:50 < zyp> is that a problem?
2018-11-07T23:30:07 < zyp> just point them all at the same function, then it's all shared :p
2018-11-07T23:30:23 < catphish> yeah i'll do that, i was hoping they were all separate though
2018-11-07T23:30:39 < zyp> what do you need that for?
2018-11-07T23:31:12 < catphish> although i guess the interrupt status register would tell me which ones were pending
2018-11-07T23:31:42 < catphish> i just want to know what pin changes to cause an interrupt, i'll have to xor instead, or look at the ISR resister
2018-11-07T23:32:00 < zyp> well, of course
2018-11-07T23:32:04 < zyp> most ISRs are shared
2018-11-07T23:32:18 < catphish> some are
2018-11-07T23:32:30 < zyp> the uart interrupts are all calling the same ISR regardless of whether it's tx or rx complete or whatever

2018-11-07T23:38:43 < catphish> shouldn't it have supply pipes?

2018-11-07T23:45:14 < Steffanx> Phone wont go with you?
2018-11-07T23:46:40 < catphish> actually the reality is that i'll have my phone in case there are any emergencies, and for utility purposes, and my laptop will be nearby
2018-11-07T23:46:58 < catphish> but still, i will be aiming to spend the week not using them
2018-11-07T23:47:42 < catphish> the reality of owning a frugal internet company is that i will be on call 24/7 until i retire

2018-11-08T00:45:12 < jadew> until now I was under the impression they went through all the trouble to build that thing, specifically for this purpose, but I don't think that was the case

2018-11-08T02:12:17 < kakimir> somewhat yes
2018-11-08T02:12:50 < kakimir> wait timezone changed here so now it's 6hours ahead of finland instead of 5hours
2018-11-08T02:13:34 < jadew> so they'll wake up sooner
2018-11-08T02:13:51 < jadew> they're so eager to work...
2018-11-08T02:16:12 < jadew> I bet that instead of changing the timezone and waking up one hour later, they just decided to wake up at the same time and work an extra hour

2018-11-08T02:26:13 < Laurenceb124> am I screwed or might it work?
2018-11-08T02:29:28 < kakimir> start with 3mm
2018-11-08T02:29:33 < kakimir> make pilot hole
2018-11-08T02:29:33 < Laurenceb124> k
2018-11-08T02:29:42 < Laurenceb124> I only need some 6mm holes
2018-11-08T02:29:51 < kakimir> how thick material?
2018-11-08T02:29:55 < Laurenceb124> couldnt get the bits to penetrate the surface earlier
2018-11-08T02:30:00 < Laurenceb124> about 4mm thick rolled sheet
2018-11-08T02:30:09 < kakimir> your bits are shitten
2018-11-08T02:30:31 < Laurenceb124> I heard that attacking the surface with a grinder might help
2018-11-08T02:30:38 < Laurenceb124> just so the bit has something to bite
2018-11-08T02:30:59 < Laurenceb124> might try that tomorrow + more pressure with lots of oil
2018-11-08T02:30:59 < kakimir> remember always when drilling drill bit needs to be cutting
2018-11-08T02:31:08 < Laurenceb124> ok
2018-11-08T02:31:47 < kakimir> if it's not - not enough pressure or too high rpm
2018-11-08T02:32:01 < kakimir> or drill bit is shitten
2018-11-08T02:32:37 < Laurenceb124> ok
2018-11-08T02:32:45 < kakimir> and that happens in like 3 seconds if there is insufficient pressure and drill bit stops cutting
2018-11-08T02:33:02 < Laurenceb124> yeah my electric drill is quit high rpm, even on min setting :(
2018-11-08T02:33:14 < Laurenceb124> maybe I should try battery screwdriver?
2018-11-08T02:33:21 < kakimir> if you see discoloration in tip it's shitten then
2018-11-08T02:33:26 < Laurenceb124> ok
2018-11-08T02:35:45 < kakimir> I'd recommend buying 3mm cobalt drill bit for pilot holes generally
2018-11-08T02:38:25 < kakimir> remember to place your knee under the sheet when you drill

2018-11-08T03:02:02 < kakimir> with bigger ones it is easy to underestimate right pressure and friction destroys the tip

2018-11-08T04:09:37 < aandrew> catphish: you don't align the bits
2018-11-08T04:09:40 < aandrew> you know the bit rate
2018-11-08T04:09:45 < aandrew> so you oversample and look for the start
2018-11-08T04:09:50 < aandrew> say you're 8x oversampled
2018-11-08T04:10:02 < aandrew> when you detect the start, you know the next bit will be 8 samples later
2018-11-08T04:13:49 < catphish> that makes sense, i did consider that approach, and that *is* aligning the bits, in so much as that you detect the start of a bit, then know where the middle of each subsequent bit should lie

2018-11-08T04:17:38 < catphish> my main worry with that was essentially: how long do i persist with the assumption of knowing where the bits will lie?
2018-11-08T04:20:25 < catphish> anyway, i've been over this in my head, and my implementation seems super cpu-light, automatically disregards noise without mistakenly aligning to that noice for any period, and works (not that the latter is that important in the forum of irc opinion)
2018-11-08T04:21:37 < aandrew> catphish: rfid messages are very small
2018-11-08T04:21:51 < aandrew> you should be fine for the entire message
2018-11-08T04:22:08 < aandrew> but voting comes in handy too for this as it'll likely hold on to a longer message
2018-11-08T04:22:28 < bitmask> can you explain/link voting real quick?
2018-11-08T04:22:33 < aandrew> but you can always run the capture interrupt and "nudge" your sample point as edges come in
2018-11-08T04:22:43 < aandrew> bitmask: sure: if you're oversampling by 8x
2018-11-08T04:22:45 < catphish> i'd be interested too
2018-11-08T04:22:59 < catphish> the danger i see is that the first transition it sees is noise, and it then speds a while reading garbage
2018-11-08T04:23:14 < aandrew> and you're using a 3 bit vote, you look at the bit that you think is the sample point, plus the one before, plus the one after
2018-11-08T04:23:19 < aandrew> 2 out of 3 wins
2018-11-08T04:23:42 < aandrew> eg if it's 110 or 101 or 011 that's a '1', otehrwise zero
2018-11-08T04:24:11 < aandrew> more oversampling and/or more votes gives you more confidence in the value of the bit
2018-11-08T04:24:27 < aandrew> catphish: sure, noise is always an issue but the rfid messages are infrequent and small
2018-11-08T04:24:32 < bitmask> I see
2018-11-08T04:24:37 < aandrew> so if you waste a couple msec reading garbage, so be it
2018-11-08T04:24:54 < aandrew> the chances that you will miss an actual message because you were too busy decoding noise is pretty small
2018-11-08T04:26:26 < catphish> so, what if i just blindly take several samples at the expected bitrate?
2018-11-08T04:26:35 < catphish> do i need to wait for an initial transition?
2018-11-08T04:26:53 < catphish> or can i just do it conatantly at the expected bitrate?
2018-11-08T04:26:58 < aandrew> you could do continuous capture, but how often are you expecting rfid cards?
2018-11-08T04:27:22 < aandrew> the edge detect to start is just handy for letting your cpu sleep most of the time
2018-11-08T04:27:38 < catphish> well the point might be moot, because i probably get transitions when there's no card
2018-11-08T04:30:00 < catphish> the circuit works by ac coupling the detected envelope and comparing it to 0v, so there's probably always junk on the lines
2018-11-08T04:30:38 < aandrew> test and see
2018-11-08T04:30:42 < aandrew> I bet there's less than you think
2018-11-08T04:31:01 < aandrew> when I did my 433mhz receiver (before sdr was a thing) I took the naive approach like you did here
2018-11-08T04:31:12 < aandrew> edge interrupt and measure time between edges to determine 1 and 0
2018-11-08T04:31:42 < catphish> anyway, that aside, what would happen if i just took 5 samples at bit intervals?
2018-11-08T04:32:14 < catphish> i assume they'd either be perfect, all the same, or they'd lie on the transitions
2018-11-08T04:39:44 < catphish> anyway, i should sleep, i might try some voat base sampling, but moderately happy with this solution, mostly with its ability to instantly restart and read valid data while in the middle of trying to process noise

2018-11-08T06:32:59 < bitmask> hmm so how do you figure out how much heating wire to use? Do I want to always be switching it on and off, even at full power, or find the lowest wattage that can be left on constantly and not be too hot for full power and pulse for lower settings
2018-11-08T06:33:54 < bitmask> I have it connected for 12W right now and it heats up to hot in about 10 seconds
2018-11-08T06:49:58 < bitmask> yea thats what I'm worried about
2018-11-08T06:50:30 < bitmask> its hard to tell without testing and I only have one shot at this for now so I dont wanna screw it up

2018-11-08T06:52:47 < bitmask> well I just mean its hard to test different resistances/lengths without actually cutting it and putting it inside the jacket.  so if I choose poorly I'm stuck with that length segments
2018-11-08T06:53:03 < bitmask> its 8 ohm/m
2018-11-08T06:53:08 < bitmask> I'm using 12v
2018-11-08T06:53:43 < bitmask> 12v @ 1-1.5A heats up nicely but I probably dont need that much

2018-11-08T06:56:26 < bitmask> and I'll probably have 4-6 separate wires so I dont want too much at once.  maybe like 2 'zones' of 2-3 wires each and only one zone on at a time
2018-11-08T06:56:38 < bitmask> with each zone being about 2A

2018-11-08T06:56:48 < bitmask> maybe less
2018-11-08T06:59:50 < bitmask> its 1.5A for 1 meter, so 18w

2018-11-08T07:01:43 < bitmask> yea, each single length is what I'm not sure about though, I might just try 1m
2018-11-08T07:02:55 < bitmask> not sure, like I said, I'm not sure how it will feel when actually being used, I'm just touching the bare wire.  I'll be encasing it in silicone too so that will change things as well
2018-11-08T07:03:33 < bitmask> 10s I guess isn't bad though, I dont think I want segments of more than 1 meter anyway
2018-11-08T07:03:39 < bitmask> that would be a pain to work with
2018-11-08T07:05:28 < bitmask> right but I was gonna have 4 panels (two front, two back) and then special small ones for hand warmers and maybe neck
2018-11-08T07:05:40 < bitmask> I'm going to encase the wire in silicione to keep it spaced evenly
2018-11-08T07:05:56 < bitmask> well I already have the wire, I have 5 meters to play with
2018-11-08T07:06:06 < bitmask> I think that should be plenty

2018-11-08T09:08:47 < Thorn> is x = x++; UB in c/c++?
2018-11-08T09:11:00 < jpa-> google says yes   https://stackoverflow.com/questions/949433/why-are-these-constructs-using-pre-and-post-increment-undefined-behavior
2018-11-08T09:11:25 < Steffanx> My google also said yes.
2018-11-08T09:14:15 < Thorn> so there is no sequence point after the right hand side of = is evaluated?
2018-11-08T09:21:04 < jpa-> i think in C++17 there is
2018-11-08T09:23:48 < jadew> IMO it should translate to what Haohmaru said, is that what it's meant to do in C++17, jpa-?
2018-11-08T09:24:24 < jadew> although, it's a bit odd, because you're not incrementing the same value anymore
2018-11-08T09:24:35 < jadew> that's probably the reason they made it undefined
2018-11-08T09:24:59 < jadew> you assign x, so x is not the same (although it is)
2018-11-08T09:25:43 < jadew> but you could have x = x++ + 1; in which case it won't be the same
2018-11-08T09:26:05 < jadew> so you're incrementing a value that was changed before usage, resulting in something different than the original value + 1
2018-11-08T09:26:08 < jpa-> AFAIK C++17 always evaluates right side first

2018-11-08T09:26:51 < jpa-> thus becoming   tmp = x++; x = tmp;   which is same as   x++;
2018-11-08T09:27:42 < jadew> that would make it not change
2018-11-08T09:28:08 < jpa-> hmm, true
2018-11-08T09:28:11 < jadew> I guess that's good behaviour true
2018-11-08T09:28:18 < jadew> *too
2018-11-08T09:29:03 < jadew> yeah, I don't mind the c++17 way of doing it
2018-11-08T09:29:43 < jadew> what I'm not clear on is what happens when you have multiple post increments in the same operation
2018-11-08T09:30:12 < jadew> I always avoided that scenario because it seemed too icky, but now that we're talking about it I'd like to know
2018-11-08T09:30:36 < jadew> for example a++ * 2 + a++
2018-11-08T09:31:01 < jadew> will it be equal to a * 2 + a?
2018-11-08T09:31:03 < Thorn> that is UB
2018-11-08T09:31:18 < jadew> how about if I use paranthesis?
2018-11-08T09:31:22 < jadew> does that change anything?
2018-11-08T09:31:23 < Thorn> there are no sequence points inside that expression
2018-11-08T09:31:30 < jadew> a++ * 2 + (a++)
2018-11-08T09:31:37 < jadew> same thing?
2018-11-08T09:31:52 < Thorn> () don't change anything afaik
2018-11-08T09:32:00 < Thorn> wrt sequence points
2018-11-08T09:32:21 < jadew> thing is
2018-11-08T09:32:37 < jadew> if the sequence point isn't changing, why is a not the same value across the entire expression?
2018-11-08T09:32:44 < jadew> and then it can just be incremented twice

2018-11-08T09:37:23 < zyp> if you are writing code where you have to worry a lot about sequence points and stuff, you should probably consider restructuring it
2018-11-08T09:37:59 < zyp> even if you get it right, it doesn't result in very obvious or readable code, which makes it a hassle to maintain later on
2018-11-08T09:38:10 < jadew> yeah, if something feels wrong, you should just re-write it until it doesn't
2018-11-08T09:38:16 < jadew> if anything, only for clarity

2018-11-08T11:57:18 < Steffanx> Sores.
2018-11-08T12:00:16 < Sadale> well, this one beats me.
2018-11-08T12:00:24 < karlp> nice 404 page on microchip dongs :)
2018-11-08T12:00:33 < Sadale> jpa-, As a newbie I've no idea on what's going on. Good luck on fixing it anyway. :3
2018-11-08T12:00:43 < Sadale> I understand the problem. But I've no idea on what's wrong.
2018-11-08T12:02:05 < karlp> spinkle dsb's around and hope it fixes it?
2018-11-08T12:02:10 < karlp> looks super shady...
2018-11-08T12:02:42 < Sadale> jpa-, Just hypothesis. Could it be those flash fetch latency thingie? like when the microcontroller is running at a high clock rate, one have to change a register to increase the flash read latency or something.
2018-11-08T12:02:52 < Sadale> It isn't likely to be the case. But it's just a guess.
2018-11-08T12:06:41 < jpa-> Sadale: it is a good guess, but with the value in the register seeming correct it seems unlikely
2018-11-08T12:06:58 < jpa-> but now the bug just randomly disappeared in the middle of me debugging it
2018-11-08T12:07:15 < Sadale> I see. That's weird.
2018-11-08T12:07:29 < Sadale> couldn't help. sorry. Please wait for someone else for help. :(
2018-11-08T12:08:12 < jpa-> i put a asm("dmb":::"memory"); after the copy loop, and then it worked; then i removed it to double-check, and it still worked; and now i restored the previous firmware binary and it still works
2018-11-08T12:08:40 < jpa-> ... hmm wait, yeah, it probably works because the correct data stays in ram across reboots, so it is not replacing it with incorrect data but just not writing it
2018-11-08T12:08:50 < zyp> haha
2018-11-08T12:09:16 < jpa-> but i don't really see what dmb would do there, have to test further
2018-11-08T12:10:58 < jpa-> hmm no, it cannot be that either because it is static allocation and gets cleared by crt0
2018-11-08T12:11:32 < jpa-> time to power off everything for a while and go eat ->

2018-11-08T12:33:24 < jpa-> "it looks like that memory gets corrupted only at addresses, where breakpoints are being placed"    ... ok
2018-11-08T12:33:53 < jpa-> that explains why it was so weird when i was debugging, but now i have to figure out why it crashes normally

2018-11-08T12:35:14 < jpa-> i guess my normal crash is a normal bug somewhere totally else; when chasing it up i set a breakpoint in ram and then ram copys started to corrupt

2018-11-08T13:24:39 < kakimir> you need to go deeper
2018-11-08T13:32:22 < jpa-> i don't think the bug is in the debugger, more like in cortex-m4 core

2018-11-08T13:42:31 < jadew> I have a question
2018-11-08T13:43:00 < jadew> are long nails not weird around the world?
2018-11-08T13:43:09 < jadew> (on men)
2018-11-08T13:43:51 < jadew> I keep seeing these tech channels with the hosts displaying long and sometimes dirty nails
2018-11-08T13:44:06 < jadew> are people not ashamed of that in other countries?
2018-11-08T13:45:08 < jadew> you can see more than 1mm of "white"
2018-11-08T13:45:38 < jadew> sometimes with dirt underneath
2018-11-08T13:46:55 < Steffanx> Whats wrong with 1mm of white jadew?
2018-11-08T13:47:03 < jadew> 1mm is fine
2018-11-08T13:47:05 < Steffanx> Fuck ultrashort nails
2018-11-08T13:47:08 < jadew> more than that it's too much
2018-11-08T13:47:18 < Steffanx> Nails are useful
2018-11-08T13:47:22 < jadew> for what?
2018-11-08T13:47:44 < kakimir> as a weapon
2018-11-08T13:47:45 < jadew> you can't even type well with long nails
2018-11-08T13:47:49 < karlp> I don't understand the obsession people have with minor parts of other people's bodies.
2018-11-08T13:48:29 < jadew> karlp, it's not an obsession, it just pops up, because in here, people simply clip their nails
2018-11-08T13:48:36 < jadew> you don't see that
2018-11-08T13:49:10 < jadew> I had a similar shock when I went to germany for the first time and saw women on the street with dirty nails on their feet
2018-11-08T13:49:19 < jadew> I mean... wtf?
2018-11-08T13:49:24 < karlp> again, shock is a pretty big word for something that's not yours
2018-11-08T13:49:50 < jadew> might seem like that to you, but there is a reason nobody here is like that
2018-11-08T13:49:57 < jadew> we're ashamed into taking care of our nails
2018-11-08T13:50:11 < jadew> so seeing someone that doesn't comply to that is... out of the ordinary
2018-11-08T13:50:37 < karlp> COMPLY! OBEY AUTHORITY! 
2018-11-08T13:51:02 < kakimir> long nais get shit under them
2018-11-08T13:51:03 < karlp> my mismatched nail lengths, colour and cleanliness is my protest against the man
2018-11-08T13:51:04 < jadew> given your answers, I assume it has to do with my culture
2018-11-08T13:51:25 < jadew> kakimir, yes, but chicks have long nails here too and they're fucking spotless
2018-11-08T13:52:00 < jadew> you'd have to go to the country side to find someone with dirty nails
2018-11-08T13:52:20 < jadew> and it would be an old guy, working the field or something
2018-11-08T13:55:24 < kakimir> like me

2018-11-08T15:04:23 < PeterM> am building a solid state power distribution thing, connector seems perfect, 12 reasonable high current contacts, 27 for lower power and control.
2018-11-08T15:05:21 < PeterM> i've seen the connector used on ECUs, along wiht the 24 pin
2018-11-08T15:06:08 < PeterM> https://www.ecumaster.com/products/emu-black/ is the product ive seen them used on
2018-11-08T15:07:11 < PeterM> legit aptiv/delphi part markings on the housings and mating connectors 
2018-11-08T15:09:11 < englishman> in my experience: good luck with that
2018-11-08T15:09:20 < englishman> unless you are buying 500k of them
2018-11-08T15:09:23 < dongs> ask samtec
2018-11-08T15:09:24 < englishman> and have a purchasing dept
2018-11-08T15:09:26 < dongs> they'll help you

2018-11-08T15:09:36 < englishman> yes, ask scamtec if you want to cease operations immediately
2018-11-08T15:09:42 < PeterM> as i said, the 24 pin variant are very very commonly available
2018-11-08T15:09:44 < englishman> and go back to scooping ice cream
2018-11-08T15:09:49 < dongs> PeterM: why cant you buy from china?
2018-11-08T15:10:01 < dongs> i mean if its available there who cares
2018-11-08T15:10:18 < PeterM> they're all clones, no actual aptive/delphi part
2018-11-08T15:10:42 < PeterM> i thought i'd look into how much the legit ones were before i started looking at clones
2018-11-08T15:10:48 < dongs> what the fuck is that thing in the centetr of that emublack
2018-11-08T15:10:53 < dongs> is that some IP67 usb port
2018-11-08T15:11:05 < dongs> https://www.ecumaster.com/wp/wp-content/uploads/2016/11/emu-black-05-front.png
2018-11-08T15:12:06 < englishman> probably
2018-11-08T15:12:19 < englishman> you would connect it to a computer to program and tune
2018-11-08T15:12:47 < PeterM> its sealed, so no water ingress into the ecu, and its made out of cast aluminium so you'll snap your cable before you damage the port, but if you sat it in water it would corrode
2018-11-08T15:13:32 < englishman> wow $1100 that is a great deal
2018-11-08T15:13:56 < PeterM> it is very nice for the money
2018-11-08T15:14:26 < englishman> do they sell harnesses? maybe you can get a couple connectors from them
2018-11-08T15:15:20 < PeterM> you can but the housings from them, and hte terminals are the same as the 24 pin so you can get them from DK etc, but the PCB mount connectors are no go
2018-11-08T15:15:24 < englishman> nice dashes and stuff
2018-11-08T15:15:26 < englishman> k type inputs
2018-11-08T15:15:29 < englishman> cool
2018-11-08T15:16:13 < PeterM> it was the cheapest ECU that could do DBW and sequential ignition/injection on a 6 cylinder
2018-11-08T15:16:35 < PeterM> the next option was around $2100
2018-11-08T15:16:49 < englishman> yeah dbw is rare

2018-11-08T15:20:21 < englishman> with the exchange
2018-11-08T15:21:07 < englishman> yours looks better still
2018-11-08T15:22:00 < PeterM> nah, that is a lot cheaper than when i last looked
2018-11-08T15:22:20 < dongs> anyway whats wrong with that connector other than it being china-only?
2018-11-08T15:23:26 < PeterM> nothing, i jsut wanted to see if i could find legit ones before i bought clones
2018-11-08T15:23:34 < dongs> ya you wont
2018-11-08T15:23:59 < englishman> clones will probably be the more reliable supply line
2018-11-08T15:24:16 < englishman> even if you get thru to the mfg there will probably be 80 week leadtimes
2018-11-08T15:24:37 < PeterM> yeah, i thought because i could find the 24 pin version from DK and shit i might just be missing something and not finding the 39 pin versions
2018-11-08T15:24:47 < PeterM> was worth a look
2018-11-08T15:26:17 < PeterM> retarded things have happened when looking at connectors before, like  it'll be a 39 pin connector, but since 12 pins are twice as wide as the other 27 they'll call it a 51 pin (12+12+27) instead of 39 (12+27) or some shit

2018-11-08T19:27:00 < Brittany> Hello. I've been checking ADC results from my STM32F3 microcontroller. I'm running a sampling rate of 601.5 cycles per sample, sampling 10 channels on an ADC in scan mode. My CPU/ADC clock is at 72MHz. Assuming each sample is taken one at a time, this should mean 72,000,000/6015 samples per second, or ~12,000 samples. Instead, I receive approximately double. Is this because the ADC samples multiple channels concurrently in scan mode

2018-11-08T21:43:13 < catphish> the specific train i guess
2018-11-08T21:44:14 < catphish> so 10 coils at useful places under the track, then the stm32 detects tags and reports their location and ID
2018-11-08T21:44:47 < catphish> i don't know what his software will do with this information :)
2018-11-08T21:46:25 < englishman> why dont you have a series of braille-like dots on the underside of the train, and a small switch underneath, so when the train passes over it emits a morse code style series of modulated tones
2018-11-08T21:47:01 < englishman> those tones get piped into mechanical turk and some paki decodes 5000 signals for $2
2018-11-08T21:47:30 < jpa-> or barcode and IR send/receiver on the underside :P
2018-11-08T21:47:52 < catphish> englishman: that's actually kinda cool
2018-11-08T21:48:16 < catphish> barcode is likely dramatically more expensive than rfid

2018-11-08T21:48:27 < jpa-> why?
2018-11-08T21:48:29 < englishman> jpa-: a pal did that for some rf detector, a little robot went along a track until a barcode scanner did a successful read

2018-11-08T21:51:16 < catphish> i've never even heard of a PSoC5
2018-11-08T21:51:36 < catphish> is that an arm + fpga?
2018-11-08T21:52:42 < englishman> petty shit-on-chip version 5 (this time it'll be good!!! oh btw version 6 is out soon)
2018-11-08T21:52:43 < ds2> sort of...it is simplier then a FPGA

2018-11-08T21:53:11 < ds2> I think the GUI has the IP to create more UARTS is needed
2018-11-08T21:53:23 < ds2> other then costs, I like the PSoC. It does what i need
2018-11-08T21:53:32 < ds2> what's your objection to the PSoC?
2018-11-08T21:54:33 < englishman> idk
2018-11-08T21:54:41 < englishman> just disappointed
2018-11-08T21:54:44 < ds2> so far it is the best thing for messing with analog sensors. avoids having to constantly changing out resistors or rewiring stuff
2018-11-08T21:54:45 < englishman> the few times i tried to spin on eup
2018-11-08T21:54:53 < catphish> but, the stm32 is like £2 and hopefully it can process lots of these inputs
2018-11-08T21:56:59 < ds2> yes, cost is a sore point

2018-11-08T22:07:09 < catphish> how is that not good?
2018-11-08T22:07:20 < sync> because it costs you more
2018-11-08T22:08:02 < catphish> i've been hearing that premature optimization is bad for years, i'm a software engineer, it's nonsense, when people write good software to begin with, nobody has to optimize (ie totally rewrite) it later
2018-11-08T22:08:33 < BrainDamage> embedded is a bit different though, for one, you don't have to contend resources with other programs
2018-11-08T22:08:40 < BrainDamage> so it either fits the platform or doesn't

2018-11-08T22:09:43 < BrainDamage> and ofc, you'll need *some* insight to take some design decisions to avoid rewriting large portions of your program, that's where experience comes in
2018-11-08T22:10:00 < catphish> also, sure, there's no point really cost optimizing, but makes sense to choose the cheapest option that fits the need (and doesn't require a lot of extra work to fit it in)
2018-11-08T22:10:14 < catphish> i mean, this code i'm writing would run on a xeon, but i'm not gonna start there
2018-11-08T22:10:36 < catphish> stm32 seems like a sane starting point for most embedded stuffs
2018-11-08T22:10:43 < catphish> and by chance, it's cheap :)
2018-11-08T22:10:51 < sync> oftentimes you do not know if your idea is gonna work
2018-11-08T22:11:01 < sync> so you have to figure it out and then integrate it in the product
2018-11-08T22:11:29 < sync> at least in the projects I have been involved much of the software had to be rewritten or at least reworked to some degree in the final product
2018-11-08T22:12:16 < sync> and with hardware I usually choose an option that will most likely do the job but might not be the cheapest or simplest solution just to see if the idea is workable
2018-11-08T22:12:41 < sync> if it comes to mass production it wil be reengineered to the targeted production cost or just be more expensive
2018-11-08T22:13:12 < englishman> it's almost always faster and cheaper to do your proof big and expensive then cost and size down later
2018-11-08T22:13:24 < englishman> assuming your time is not worthless
2018-11-08T22:13:33 < englishman> since you're making your own pnp, that part is up for debate

2018-11-08T22:39:33 < Steffanx> Some dont understand that catphish 
2018-11-08T22:40:11 < catphish> but i'm sure i'm not exactly a pro at cost optimizing yet anyway, i just choose something that'll work and doesn't seem silly expensive
2018-11-08T22:42:01 < Hamilton> Is there any *standard way (tm)* for when your RF transmitter packer limit is 32 bytes and you want to sent arbitrary large packets? I'm specifically talking about nRF24l01+...Does bettering the protocol transcends to re-inventing TCP/IP?
2018-11-08T22:43:49 < BrainDamage> the cheap way is just have a bit that marks for "packet not finished"
2018-11-08T22:44:16 < catphish> Hamilton: i'd say a header with an "end of data" flag
2018-11-08T22:44:24 < catphish> what BrainDamage said
2018-11-08T22:44:51 < Hamilton> BrainDamage, yeah or the first packet be "number of packets"...The driver has CRC capabilities (for that 32 bytes though)...but what if there are some packet loss?
2018-11-08T22:45:45 < BrainDamage> if you have number of packets, then you're limited by the counter size, so not "arbitrary large", to avoid packet loss you either crc the whole packet or you add a sequence counter
2018-11-08T22:46:11 < BrainDamage> cheapest is crc the whole shit, and retransmit, provided your error rate is sufficiently low
2018-11-08T22:48:05 < Hamilton> thanks. So there is no keyword like tcp or udp for these stuff that I should be aware of?
2018-11-08T22:48:47 < BrainDamage> keep in mind one thing though
2018-11-08T22:49:08 < BrainDamage> 32 bytes for packet counter is quite a bit
2018-11-08T22:49:11 < BrainDamage> so unless you really really "arbitrary large", it's enough for most things
2018-11-08T22:49:34 < Hamilton> I wonder what bluetooth like SPP profile uses?

2018-11-09T02:22:40 < mawk> with ethereum
2018-11-09T02:22:47 < jadew> really?
2018-11-09T02:22:55 < mawk> and 200€ with scalp trading with bitcoin
2018-11-09T02:22:55 < jadew> that doesn't sounds bad
2018-11-09T02:22:59 < mawk> playing with leverage
2018-11-09T02:23:11 < mawk> well for eth I was quite lucky, I bought at the right time
2018-11-09T02:23:22 < mawk> but if you can somehow predict the market you can do that
2018-11-09T02:23:28 < jadew> ok, I really want to get into this
2018-11-09T02:23:42 < mawk> there are few ways, one is purely technical analysis, looking at the charts and analyzing resistance lines, patterns, shit like that
2018-11-09T02:23:50 < mawk> other method is to scroll twitter to find the next big thing
2018-11-09T02:23:57 < mawk> watch for big announcements that will move the charts
2018-11-09T02:24:02 < jadew> yeah, you have to follow both
2018-11-09T02:24:19 < jadew> what scares me about bitcoin is that it seems it has huge spikes
2018-11-09T02:24:25 < mawk> yeah
2018-11-09T02:24:33 < jadew> someone is buying & selling big quantities
2018-11-09T02:24:34 < mawk> well you can win money with these
2018-11-09T02:24:39 < mawk> yes
2018-11-09T02:24:51 < mawk> before a drop you sell a lot of btc, buy them back after the drop
2018-11-09T02:24:55 < mawk> keep the difference money
2018-11-09T02:25:06 < jadew> yeah, but how do you know when the drop is going to happen?
2018-11-09T02:25:22 < mawk> you typically have some signs
2018-11-09T02:25:32 < mawk> the chart breaking a resistance line, etc
2018-11-09T02:25:43 < jadew> interesting
2018-11-09T02:25:44 < mawk> I don't know how close to astrology this is, I didn't research it much
2018-11-09T02:25:51 < jadew> heh
2018-11-09T02:25:53 < mawk> some people criticize that technical analysis thing
2018-11-09T02:25:57 < mawk> and some other seem to make money out of it
2018-11-09T02:27:14 < mawk> and you don't even have to own btc to sell them before a drop, you can borrow them and sell them at a good price, buy them back at the bad price and return them 
2018-11-09T02:27:35 < jadew> hah
2018-11-09T02:27:43 < mawk> and you don't even have to have lots of money, you can use a multiplicative leverage
2018-11-09T02:27:54 < mawk> which multiply either the profits or the loss
2018-11-09T02:28:10 < jadew> interesting
2018-11-09T02:28:16 < jadew> so someone is gambling on your gamble?
2018-11-09T02:28:27 < jadew> basically they're gambling that you're going to fail?
2018-11-09T02:28:33 < mawk> that someone isn't quite gambling, kraken won't let you borrow if you don't have enough collateral
2018-11-09T02:28:46 < mawk> and when your losses start to exceed your collateral kraken will automatically liquidate your positions
2018-11-09T02:28:51 < mawk> so you can't be in debt
2018-11-09T02:29:17 < mawk> no, the person making the loan isn't gambling
2018-11-09T02:29:23 < mawk> it's just making a guaranteed loan
2018-11-09T02:29:39 < mawk> if you lose or you win, they get their money back + interest
2018-11-09T02:29:55 < jadew> no, I mean with multiplicative leverage
2018-11-09T02:29:57 < mawk> kraken does the loan for you from banks I think, or maybe from their own funds
2018-11-09T02:29:59 < jadew> if you win, who pays?
2018-11-09T02:30:41 < mawk> nobody really pays, it's just that the drop in price is your payoff
2018-11-09T02:30:54 < mawk> you sold at a higher price than you bought back, you can keep the difference
2018-11-09T02:31:04 < mawk> the money is created from whatever made that fluctuation happen
2018-11-09T02:31:29 < jadew> but you said you'd use less money for that, and only the winnings and the losses get multiplied
2018-11-09T02:32:01 < jadew> I probably have to start reading on it
2018-11-09T02:32:12 < mawk> yeah it's just a mechanism that allows you to borrow more money that is currently on your account
2018-11-09T02:32:23 < jadew> I see
2018-11-09T02:32:31 < mawk> but at the time t=0 when you make the loan, if you just bought immediately all the btc you sold with the loan money no money would have been lost
2018-11-09T02:32:39 < mawk> so that loan of more than your collateral is allowed
2018-11-09T02:33:13 < mawk> and your positions will be liquidated when the losses from buying back the btc you sold are starting to get close to your collateral funds
2018-11-09T02:33:31 < mawk> https://support.kraken.com/hc/en-us/articles/203053106-Explanation-of-leveraged-trading
2018-11-09T02:33:51 < jadew> thanks
2018-11-09T02:35:04 < mawk> you can start playing with little amounts, and don't put more than you can afford to lose
2018-11-09T02:35:33 < mawk> and don't use your gas money, your family vacation money or the mortgage money or anything
2018-11-09T02:36:01 < jadew> was planning to start with the gas money
2018-11-09T02:36:28 < mawk> lol
2018-11-09T02:36:49 < jadew> I'll read a bit about it
2018-11-09T02:37:07 < jadew> I'll have to talk to my accountant first anyway, to make sure it's worth it from a tax perspective as well
2018-11-09T02:37:33 < mawk> if you feel naughty nobody can force you to declare that money
2018-11-09T02:37:40 < mawk> lots of stuff can be bought with bitcoin nowadays
2018-11-09T02:38:20 < jadew> surely kraken will spit out my name in 0.1 ms if someone asks "what Romanian customers do you have?"
2018-11-09T02:38:23 < mawk> lol
2018-11-09T02:38:45 < mawk> is bitcoin considered as a taxable good ?
2018-11-09T02:38:56 < mawk> I'm sure if you convert your gains to euros that would be taxable, but bitcoin I don't know
2018-11-09T02:39:04 < jadew> it's considered currency, so it might be extempt from some taxes, but I'm not 100% sure
2018-11-09T02:40:37 < mawk> if you want a fun fact, the time when your leverage losses start exceeding your collateral funds and the broker liquidates your position, it's called a margin call
2018-11-09T02:40:44 < mawk> like the movie
2018-11-09T02:41:14 < jadew> haven't seen it
2018-11-09T02:41:50 < jadew> netflix doesn't have it
2018-11-09T02:42:30 < mawk> https://www.imdb.com/title/tt1615147/
2018-11-09T02:43:18 < jadew> added to watch list, thanks
2018-11-09T02:43:26 < mawk> I'm not sure if it's a good movie
2018-11-09T02:43:29 < mawk> I don't even remember it
2018-11-09T02:45:19 < karlp> do you get automatic margin loans with this kraken place?
2018-11-09T02:45:26 < karlp> nromally  you have to apply for that specially...
2018-11-09T02:45:30 < mawk> yeah
2018-11-09T02:45:38 < mawk> you just have to have enough collateral on your account
2018-11-09T02:45:59 < mawk> so it's a safe loan for the investor
2018-11-09T02:46:12 < mawk> kraken holds the collateral, and the investor gets his interest rate
2018-11-09T02:46:19 < mawk> he can't lose anything
2018-11-09T02:46:38 < karlp> I haven't read the backlog yet actually :)
2018-11-09T02:46:58 < mawk> well you have to have your identity verified with kraken, for margin
2018-11-09T02:47:02 < mawk> but that's all
2018-11-09T02:47:04 < karlp> it just seemed odd to hear you apparently discussing margin trading, but having to discover the words for the field.
2018-11-09T02:47:34 < mawk> send your ID and proof of domiciliation

2018-11-09T03:46:42 < Laurenceb124> >The reason developed countries need a fertility rate of 2.1 is because not all children survive to adulthood and babies are ever so slightly more likely to be male 
2018-11-09T03:46:47 < Laurenceb124> incels vindicated
2018-11-09T03:46:54 < Laurenceb124> this article is highly problematic
2018-11-09T03:48:18 < jadew> "but head north-east to the Mediterranean island of Cyprus and women are having one child, on average, in a lifetime."
2018-11-09T03:48:56 < jadew> they're comparing Niger with Cyprus lol
2018-11-09T03:50:28 < jadew> it's good niger has such a high birth rate tho, they can come and continue to fuel the machine in Germany, UK, France

2018-11-09T03:53:30 < jadew> the problem is that this decline in fertility, is actually a problem in the way countries work, while at the same time being a completely normal thing
2018-11-09T03:53:51 < jadew> so instead of adapting to normality, governments will try to fix it
2018-11-09T03:55:44 < jadew> how do you go from "we're going to take a lot of money from you and will give them back to you when you're old" to "you don't have to pay for the pension fund anymore, you're on your own"
2018-11-09T03:58:12 < jadew> this would be no problem if you didn't have a lot of people relying on the working class
2018-11-09T03:58:46 < jadew> in fact, it would even go great with the automatization

2018-11-09T14:29:22 < zyp> (apparently the news is a few weeks old)
2018-11-09T14:29:25 < karlp> just you
2018-11-09T14:29:31 < karlp> we spoke about it a little bit here
2018-11-09T14:29:31 < zyp> aww :(
2018-11-09T14:29:45 < zyp> what's the verdict?
2018-11-09T14:29:57 < karlp> "who cares" 
2018-11-09T14:30:08 < karlp> armv8 doesn't bring much to the table for most of us.
2018-11-09T14:30:38 < karlp> I'm more interested in the new l4s with less flash/ram/smalelr packages
2018-11-09T14:32:32 < zyp> I guess all the hardware crypto shit they're talking about might make it unobtanium anyway
2018-11-09T14:33:36 < karlp> I mean, it's an l4, with atmv8 trustzone shits, and possibly newer usbc pd stuff.
2018-11-09T14:35:24 < qyx> the crypto would be interesting if it was able to store ecc keys and do ecc stuff on them
2018-11-09T14:35:32 < qyx> but I haven't investigated it further
2018-11-09T14:36:15 < zyp> doesn't seem to do much async crypto at all
2018-11-09T14:36:43 < zyp> but that's ok, you can do ECC in software to negotiate the AES key
2018-11-09T14:37:13 < qyx> yes but the whole purpose is void then
2018-11-09T14:37:59 < zyp> what purpose?
2018-11-09T14:38:32 < zyp> the purpose of hardware crypto is to speed up stuff vs doing it in software
2018-11-09T14:39:10 < qyx> I mean the key storage part, not the hw acceleration
2018-11-09T14:39:48 < qyx> ie. to be able to store private ecc keys securely in a hardware protected box
2018-11-09T14:40:15 < qyx> to protect them fromt he attacker and/or modified software
2018-11-09T14:40:31 < qyx> like smartcards do
2018-11-09T14:42:15 < qyx> otherwise there is no added value
2018-11-09T14:43:12 < qyx> you can do AKE in aoftware and then use hw asisted AES even without it
2018-11-09T14:44:27 < zyp> hmm
2018-11-09T14:44:40 < zyp> actually, seems like the PKA stuff is actually some ECC
2018-11-09T14:45:29 < marble_visions> microchip has announced similar chips with cortex-m23
2018-11-09T14:45:37 < marble_visions> trustzone sounds cool
2018-11-09T14:46:26 < marble_visions> i think this implementation of trustzone for deep embedded is like a fancy memory protection unit
2018-11-09T14:47:40 < zyp> the stm32wb (which also has PKA) datasheet says "Elliptic curves over prime field scalar multiplication, ECDSA signature, ECDSA
2018-11-09T14:47:43 < zyp> verification with maximum modulo size of 521 bits"
2018-11-09T14:48:18 < zyp> so it sounds like it's actually configurable for multiple curves as well, not locked to a particular one

2018-11-09T14:57:40 < qyx> and it adds another layer of complexity to things
2018-11-09T14:57:42 < qyx> so fukit

2018-11-09T23:19:42 < Steffanx> Just watched Outlaw King on Netflix. Its a nice ##stm32 movie. Chris Pine dick, titties and bloody 
2018-11-09T23:23:03 < englishman> never heard of that type of tree
2018-11-09T23:29:54 < Steffanx> Captain Kirk.
2018-11-09T23:39:53 < malinus> Steffanx: the first fighting sword fight scene was so cringy. I know it's a movie, but come on...
2018-11-09T23:40:13 < Steffanx> Yeah
2018-11-09T23:40:17 < Steffanx> True
2018-11-09T23:43:12 < qyx> so I am going to try that hyperbus DRAM on L4+
2018-11-09T23:43:19 < qyx> wish me luck
2018-11-09T23:44:22 < Steffanx> That hyperbus dram?
2018-11-09T23:44:41 < qyx> L4+ has a octospi/hyperbus interface
2018-11-09T23:45:00 < qyx> see S27KL064 for example
2018-11-09T23:45:10 < qyx> and S25FL128
2018-11-09T23:45:19 < Steffanx> Hm
2018-11-09T23:45:25 < qyx> (reading from my notes, I selected those parts some time ago)
2018-11-09T23:49:10 < malinus> qyx: what kind of application do you need fast DRAM for on a m4 mcu?
2018-11-09T23:51:05 < qyx> some on-site data processing of sampled data
2018-11-09T23:51:28 < qyx> but now it is only for playing
2018-11-09T23:52:04 < qyx> 640K on L4+ should probably suffice, as mr. Gates said
2018-11-09T23:55:32 < Steffanx> Which he never did 
2018-11-09T23:56:10 < qyx> idk
2018-11-09T23:56:48 < malinus> qyx: what kind of processing, of what kind of data?
2018-11-09T23:57:40 < englishman> L4+ was not around in 1981 so there is no possible way he could have said that.

2018-11-10T16:05:40 < con3> Can't seem to find a damn enclosure that can hit my operating temp, without costing 3 butt loads
2018-11-10T16:09:47 < kakimir> operating temp?
2018-11-10T16:10:13 < kakimir> if it start smelling it's in it's operating temperature?
2018-11-10T16:11:19 < con3> kakimir: Found a few casings but their operating temps at about 60 degrees max, got a FET in there that's gonna be hooooot
2018-11-10T16:12:11 < con3> hmm.. recently bought one of these H7's as well. thought it would be good for learning the registers a bit better, twas a mistake.
2018-11-10T16:14:34 < kakimir> typical plastic reach T2 around 80 - 120C
2018-11-10T16:14:50 < kakimir> T2 as second glassing temperature

2018-11-10T16:19:30 < dongs> the real answer
2018-11-10T16:19:49 < con3> Issue is there will be a mosfet with a 40 degree temp rise, and seeing 45 degree ambients is common
2018-11-10T16:20:13 < con3> dongs: Lots of people that I know seem to be very pro linux

2018-11-10T16:22:22 < kakimir> con3: isn't that like normal situation?
2018-11-10T16:22:34 < con3> kakimir: normal situation?
2018-11-10T16:23:09 < kakimir> pretty typical that your electronics go +40C and ambient can be +40C ?
2018-11-10T16:23:45 < con3> yeah I completely agree, just the enclosures I've been looking at for my size PCB seem to just not like that temp range
2018-11-10T16:23:55 < con3> seem to be capped at 60 maybe 70
2018-11-10T16:24:02 < con3> might just be looking at the wrong ones
2018-11-10T16:24:07 < kakimir> you need bigger enclosure

2018-11-10T17:05:22 < Steffanx> so what is this silicone crap you are doing bitmask ?
2018-11-10T17:07:38 < bitmask> for my heated hoodie project.  Instead of sewing the carbon fiber in I want it to be removable.  If its not uncomfortable I thought this would work well.  I'm creating a sheet of silicone with the carbon fiber and thermistor embedded with magnets to attach to the inside of the hoodie.  The silicone will help keep the zig zag form for the carbon fiber and hopefully is flexible enough to be comfortable
2018-11-10T17:08:21 < bitmask> so I'll have like 4 of these panels
2018-11-10T17:08:32 < bitmask> two in the front two in the back
2018-11-10T17:08:37 < kakimir> why don't you buy heated jacket from ebay
2018-11-10T17:08:59 < bitmask> because this is cheaper and I enjoy working on projects
2018-11-10T17:11:23 < bitmask> I know its hard to comprehend, but some people find DIY fun
2018-11-10T17:11:45 < BrainDamage> won't it feel uncomfortable because it blocks perspiration?
2018-11-10T17:12:11 < BrainDamage> do the silicone pads have holes in them to at least allow some vapour to flow?
2018-11-10T17:12:41 < bitmask> well its meant to be used in the cold, I doubt I'll be sweating much.  and the panels don't cover the whole area of the hoodie
2018-11-10T17:13:15 < Steffanx> With heating you will sweat.
2018-11-10T17:13:32 < bitmask> I guess, but there should be plenty of room for the vapor to go
2018-11-10T17:13:58 < bitmask> if the silicone doesnt work out I'll just sew it into some fabric or something
2018-11-10T17:14:00 < BrainDamage> I have a t-shirt with a large laminated imprint on it, and it definetly feels clammy under the surface even if I wear in the winter

2018-11-10T17:17:42 < bitmask> there will also be a shirt between the hoodie and my body so hopefully that will be enough to absorb sweat and allow it to dry out
2018-11-10T17:18:20 < bitmask> but I'm just testing stuff out, no idea how it will turn out
2018-11-10T17:21:24 < bitmask> I'm more worried about figuring out how much power to pump through it, not sure how long each 'wire' of carbon fiber should be
2018-11-10T17:22:34 < englishman> start with 240VAC per coil and go from there
2018-11-10T17:22:43 < bitmask> a bit less than 1m for 14W should be good

2018-11-10T18:45:06 < Sadale> I'll do experiment on the number of flash cycles available for the microcontroller. If it's too low, I'll switch to another microcontroller with more RAM.

2018-11-10T18:56:10 < Sadale> To be fair this game console is mostly a hobbyist project. I doubt that it'd even sell.
2018-11-10T18:56:21 < Sadale> It's just for fun :3
2018-11-10T18:56:32 < Sadale> I'm not sure if I'd even be selling it.

2018-11-10T19:03:34 < Sadale> aww I guess you're going to mock me again >_<
2018-11-10T19:03:51 < Sadale> Please spare me on this one. I don't have the money to get altium for hobbyist use.

2018-11-10T19:04:10 < Sadale> Even if I have the money my money could be better spent on something else :p
2018-11-10T19:04:10 < dongs> what's that
2018-11-10T19:04:36 < Sadale> That second language used on the game console that you don't understand.
2018-11-10T19:04:50 < Sadale> That's Toki Pona.
2018-11-10T19:05:55 < Sadale> In fact I have an idea on Toki Pona device. But that would be another project.
2018-11-10T19:06:16 < PaulFertser> Sadale: looks like a nice fun project to me
2018-11-10T19:06:27 < Sadale> Toki Pona has its own numbering system. I've thought about making a dedicated electronic device for performing arithematic operation with their numeral.
2018-11-10T19:06:28 < PaulFertser> Sadale: but where're the decoupling caps for the mcu?
2018-11-10T19:06:59 < Sadale> The power stabalization caps?
2018-11-10T19:07:29 < Sadale> I thought that I didn't need one as long as I have on for my voltage regulator/charge pump.
2018-11-10T19:07:31 < PaulFertser> Sadale: yes, those that you need as near as possible to each vcc/gnd pair of the microcontroller.
2018-11-10T19:07:38 < Sadale> s/I have on/I have one/
2018-11-10T19:07:43 < Sadale> ahh. I see. I didn't know that.
2018-11-10T19:07:56 < Sadale> why tho?
2018-11-10T19:08:13 < Sadale> Is it for power stabalization?
2018-11-10T19:08:25 < PaulFertser> Sadale: possible high frequency glitches from other parts on the board I guess.
2018-11-10T19:08:47 < Sadale> huh? I don't get it :o
2018-11-10T19:09:23 < Sadale> What sort of high frequency glitch? like power glitch?

2018-11-10T19:10:01 < PaulFertser> Sadale: I'm not an EE so I do not know the proper answer but I'd guess the possible parasitic inductance and capacitance of the power supply wires worth taking precautions of, so just in case ST recommends 100n near each vcc/gnd pair of the package.
2018-11-10T19:10:28 < Sadale> oh wait. what? There's a vcc/gnd pair? :O
2018-11-10T19:10:31  * Sadale is surprised :o
2018-11-10T19:10:52 < Sadale> I thought that it'd be alright if I just short all of the VCC and GND together.
2018-11-10T19:11:09 < jpa-> eh, pair of pins
2018-11-10T19:11:16 < jpa-> of course they all go to the same planes

2018-11-10T19:14:03 < aandrew> Sadale: basically, when digital circuitry switches it consumes current. the bypass capacitors act as temporary fast-responding batteries to supply that current. without bypass capacitors the current must come from the power supply, the path to which has considerable inductance and some resistance which slows the ability to supply power

2018-11-10T19:14:27 < aandrew> the rule of thumb is a single 100nF capacitor for every power pin on the device, located as close to the pin as possible (to minimize inductance)

2018-11-10T19:14:58 < dongs> PaulFertser: nothing just looks goofy
2018-11-10T19:15:05 < aandrew> if you don't know why, then it's even more important to follow this rule of thumb
2018-11-10T19:15:22 < aandrew> failure to do this can lead to REALLY weird problems that will drive you (and us, since you'll be asking here) crazy
2018-11-10T19:16:00 < PaulFertser> dongs: I wonder then what's the most obvious part of it. If it was topor, sure, you'd guess it easily. But how handrouting a simple 2L board can give visibly different results with altium and kicad?
2018-11-10T19:16:35 < Sadale> aandrew, ahh. I see :)
2018-11-10T19:17:08 < con3> keil feels ..strange..
2018-11-10T19:17:18 < Sadale> aandrew, what does it mean by "a single 100nF capacitor for every power pin", tho?
2018-11-10T19:17:23 < aandrew> keil feels like an IDE built by Fischer-Price 
2018-11-10T19:17:34 < Sadale> aandrew, does it mean that, if there's, says, 3 pairs of power pins, I'd need 300nF?
2018-11-10T19:17:42 < aandrew> Sadale: if your chip has 10 VCC pins, then you have 10 100nF capacitors
2018-11-10T19:18:04 < aandrew> each 100nF capacitor placed as close as possible (electrically speaking) to its respective pin
2018-11-10T19:18:45 < con3> feels very weird
2018-11-10T19:18:54 < Sadale> I see.
2018-11-10T19:18:59 < aandrew> dongs swears by it. I swear at it
2018-11-10T19:19:14 < Sadale> I didn't realize that "Vcc/Gnd pair" was a thing.
2018-11-10T19:19:24 < aandrew> Sadale: it's not really
2018-11-10T19:19:25 < Sadale> I thought that those Vcc/Gnd pins are just arranged randomly.
2018-11-10T19:19:29 < aandrew> nope
2018-11-10T19:19:37 < con3> ok packs are a thing
2018-11-10T19:19:42 < Sadale> hmm. I guess I get what you guys said wrong.
2018-11-10T19:19:51 < aandrew> you'd have to talk to people who know a LOT more about ASIC design to understand why they're arranged the way they are in some cases
2018-11-10T19:20:18 < aandrew> but for us board level people you just remember the rule of thumb
2018-11-10T19:20:23 < Sadale> aandrew, Let's see if I get what you said correctly.
2018-11-10T19:21:09 < Sadale> aandrew, For example, if there's a microcontroller that pin 9/10 is a Vcc/Gnd pair, and pin 17/18 is another pair, does it mean that I should add a 100nF cap on pin 9/10, and another cap between pin 17/18?
2018-11-10T19:21:32 < aandrew> Sadale: forget pairs
2018-11-10T19:21:41 -!- Thorn [~Thorn@unaffiliated/thorn] has joined ##stm32
2018-11-10T19:21:52 < aandrew> Sadale: in your example, you would place 100nF as close as possible to 9 and another as close as possible to 17
2018-11-10T19:22:15 < Sadale> ahh.
2018-11-10T19:22:17 < aandrew> Sadale: normally you have a nice ground plane you connect all the grounds to
2018-11-10T19:22:20 < Sadale> right. All grounds are connected.
2018-11-10T19:22:23 < Sadale> I get the idea now.
2018-11-10T19:22:58 < Sadale> so what I have to do is to add a 100nF cap for every Vcc pin.
2018-11-10T19:24:32 < con3> "unlike other ide's you can't just start writing code, you have to configure the fuckn thing" ...fun...
2018-11-10T19:25:44 < PaulFertser> I've seen a board routed by a special PCB guy at work that had 5 of those 100nF caps all cozily placed together _on another board_ (no netlist violation thanks to a board-to-board connector).
2018-11-10T19:26:30 < Sadale> what? another board?
2018-11-10T19:27:04 < PaulFertser> Yes, the design needed to use two PCBs due to space constraints.

2018-11-10T20:23:06 < con3> i dont know what to believe on this channel anymore,,
2018-11-10T20:23:19 < Steffanx> 142 people, 140 opinions
2018-11-10T20:24:00 < con3> so do you guys primarily program stm's?
2018-11-10T20:24:12 < Steffanx> i dont.
2018-11-10T20:24:16 < con3> assuming from the channel name
2018-11-10T20:24:23 < con3> what do you program Steffanx?
2018-11-10T20:24:48 < Steffanx> What not? Mainly cortex-m[whatever] though
2018-11-10T20:25:28 < Steffanx> :P
2018-11-10T20:25:29 < con3> ah ok, seems like as soon as you've got a feeling for cmsis, switching between manufacturers doesn't really matter
2018-11-10T20:25:46 < jpa-> couldn't be farther from the truth IMO
2018-11-10T20:26:03 < Steffanx> in the ends its just a bunch of registers :P
2018-11-10T20:26:12 < con3> well I'm an idiot, so I don't know ¯\_(ツ)_/¯
2018-11-10T20:26:20 < Steffanx> read the datasheet and do with it what you want
2018-11-10T20:26:41 < jpa-> any cross-manufacturer abstractions are so high level that you can only get the very simple stuff done portably
2018-11-10T20:26:51 < con3> Steffanx: That doesn't sound right, where's the crying step?
2018-11-10T20:27:12 < Steffanx> that only happens when you dont read the datasheet good enough
2018-11-10T20:27:13 < englishman> I only use stm8, stm32 is too complicated for me
2018-11-10T20:27:20 < Steffanx> or base your code on semi-non functional exampel code
2018-11-10T20:27:37 < con3> Steffanx: RTFM has really resonated with me
2018-11-10T20:27:45 < jpa-> crying happens if you only read datasheet and don't read refman
2018-11-10T20:27:58 < Steffanx> true.
2018-11-10T20:28:06 < jpa-> or if you set a breakpoint in ram
2018-11-10T20:28:08 < Steffanx> unless you have one of those that have stuff in the datasheet :P

2018-11-10T20:28:47 < Steffanx> Best is with nxp i had last week. Their lib had code like: int delay = 1000; /* Delay for 250us */ while(delay--);
2018-11-10T20:28:59 < englishman> nice
2018-11-10T20:29:02 < Steffanx> It did delay, but it wasnt even close to 250us D:
2018-11-10T20:29:39 < con3> eh I'm not sure anymore, some forum's told me to code directly using cmsis/registers and not use abstraction. the way you guys are talking it sounds like abstractions are the norm?
2018-11-10T20:30:02 < englishman> gross
2018-11-10T20:30:12 < englishman> why rewrite all that code
2018-11-10T20:30:13 < Steffanx> especially nice because they used it in a xtal enable function. And some targets wouldnt start properly because it didnt wait long enough.

2018-11-10T20:31:34 < Steffanx> but fuck HAL indeed.

2018-11-10T20:31:45 < Steffanx> haha
2018-11-10T20:32:05 < Steffanx> the ST HAL i mean
2018-11-10T20:32:14 < Steffanx> even keil people dont use it
2018-11-10T20:32:23 < con3> use LL instead?
2018-11-10T20:32:27 < Steffanx> they tend to use stpheripheral lib or the LL functions.
2018-11-10T20:32:59 < con3> honestly is there any point in directly using the registers?
2018-11-10T20:33:13 < Steffanx> Probably.
2018-11-10T20:34:45 < Steffanx> LL is almost that. Just with some basic shifting and masking. (and a bit more but .. meh )

2018-11-10T23:14:53 < karlp> don't list the ones taht you don't depend on then?
2018-11-10T23:21:07 < qyx> it is more complicated than that
2018-11-10T23:21:29 < qyx> let's say there are services, each compiled into a static library
2018-11-10T23:21:56 < qyx> then there is a helper which defines a "service" and another one which defines a dependency on other services
2018-11-10T23:22:20 < qyx> (it is made by doing Depends on a static library target file)
2018-11-10T23:22:26 < qyx> so far, it works as expected
2018-11-10T23:23:08 < qyx> when a single service is specified, all required services are built too, if they specify additional dependencies, they are built too etc.
2018-11-10T23:23:28 < qyx> but.. there is a service implementing a configuration CLI
2018-11-10T23:23:40 < qyx> which has multiple components
2018-11-10T23:24:15 < qyx> and a CLI component can be built only if a corresponding service is built, otherwise there is a linker error
2018-11-10T23:26:28 < qyx> specifying which components are built can be probably done using Depends(service-static-lib, component.o)
2018-11-10T23:27:27 < qyx> but I cannot find any way to pass a -D to the compiler listing the dependent service name
2018-11-10T23:28:02 < qyx> because the dependencies are resolved later (not when sconscript files are executed)

2018-11-11T03:08:03 < qyx> sometimes
2018-11-11T03:09:47 < karlp> are there any motivations for non-magjack jacks other than, "I have plenty of space, and it's marginally cheaper" ?
2018-11-11T03:10:00 < karlp> or are there tunings you can do for different EMI issues or anything?
2018-11-11T03:10:16 < karlp> or are there actually different levels of isolations that people want?

2018-11-11T03:11:29 < qyx> close enough
2018-11-11T03:12:20 < PeterM> i think for PoE applicaitons you need sperate magnetics to pull ytour dc out
2018-11-11T03:12:51 < karlp> hanrun and co seem to have magjacks "with poe" but yeah, I guess poe complicates this if  you're doing it properly.
2018-11-11T03:13:46 < PeterM> yeah, you can't use a standard mag jack it has to be a poe compatible one
2018-11-11T03:14:02 < qyx> I even saw discrete transformers and common mode chokes for gige
2018-11-11T03:14:09 < qyx> from TDK
2018-11-11T03:14:58 < qyx> they claim their solution is smaller
2018-11-11T03:14:58 < PeterM> i think on a standard mag jacks they use a common core for  the transformer so a dc bias would saturate it, and also they dont generally bring out the required pins
2018-11-11T03:15:19 < PeterM> so need poe specific mag jack
2018-11-11T03:15:43 < PeterM> im sure there are lots of different reasons
2018-11-11T03:18:39 < PeterM> there are other reasons for non-mag jacks, for example people not using them for ethernet (seen plenty of ttl uart on rj45s)
2018-11-11T03:19:35 < PeterM> why you should use magjacks or not is completely up to you though
2018-11-11T03:24:52 < PeterM> hi crt
2018-11-11T03:45:47 < karlp> so, how differential does 100baset really need to be?

2018-11-11T09:42:46 < qyx> morning
2018-11-11T09:43:14 < dongs> so im taking apart this little dongle for a jap tv
2018-11-11T09:43:24 < dongs> and I see a RSAG7.820.xxxx part number on it
2018-11-11T09:43:31 < dongs> google that up, bunch of hits for Haier/HiSense
2018-11-11T09:43:41 < dongs> google further, apparently that chinkco bought toshiba TV biz last year
2018-11-11T09:45:17 < qyx> isnt 820 the well known tuner in SDR dongles?
2018-11-11T09:48:15 < dongs> no
2018-11-11T09:48:25 < dongs> part# as in on PCB
2018-11-11T09:53:47 < malinus> qyx: nah, you are thinking about the rtl-sdr 238
2018-11-11T09:54:25 < malinus> *28
2018-11-11T09:54:50 < qyx> no, I meant R820T
2018-11-11T10:00:18 < dongs> apparently that's EOL now
2018-11-11T10:00:36 < dongs> anyway, googling RSAG7.820. brings up tons of haier shit
2018-11-11T10:01:01 < dongs> or hisense etc.

2018-11-11T20:35:31 < jadew> 300 MHz, 8 Gs/s                                        
2018-11-11T20:35:39 < jadew> probably hackable from the 1k model
2018-11-11T20:37:22 < aandrew> jadew: nice scope
2018-11-11T20:37:30 < aandrew> my next scope will be expensive as fuck
2018-11-11T20:37:32 < jadew> yeah, that's freaking awesome
2018-11-11T20:37:38 < jadew> which scope are you getting?
2018-11-11T20:37:45 < aandrew> I want at least 4GHz analog bandwidth and even used they're $$$
2018-11-11T20:37:50 < aandrew> not to mention the probes
2018-11-11T20:37:59 < aandrew> 99% of the work I do I can get by just fine with a 100MHz scope
2018-11-11T20:38:06 < jadew> ah, yeah, I've been hunting for a 1 GHz one for a while and they're not cheap
2018-11-11T20:38:20 < aandrew> and to be fair, 75% of that 99% I can do with a simple logic analyzer
2018-11-11T20:38:28 < jadew> only those crusty lecroys are accessible, but from what I understand they're not great
2018-11-11T20:38:40 < aandrew> I love lecroy scopes. not so sure about the older ones though
2018-11-11T20:38:53 < sync> the older ones were nice for the day
2018-11-11T20:39:08 < aandrew> the new MSOs are holy fuckballs amaze
2018-11-11T20:41:35 < jadew> hah, that new rigol, even if you buy it with 2 channels, it comes with 4 and it's software upgradable :P
2018-11-11T20:43:05 < jadew> bottom line is probably this: 300 MHz (at least), 4 channels, MSO with sig gen for $900
2018-11-11T20:43:08 < jadew> that's not bad

2018-11-11T22:55:08 < Steffanx> Ty antto 
2018-11-11T22:55:28 < antto> so far the best LCD i've seen, altho no LCD deserves to be in the same sentence with the word "best"
2018-11-11T22:56:11 < antto> tilt, swivel, rotate to portrait mode.. nice stand
2018-11-11T22:57:30 < antto> it's also f*cking bright (good for during the day)
2018-11-11T22:58:44 < antto> i'm running it with HDMI right now, cuz the f*cking computer store had not a single DVI cable o_O
2018-11-11T22:59:03 < antto> haven't tried the card reader sh*t yet
2018-11-11T22:59:32 < qyx> is DVI still a thing?
2018-11-11T23:00:04 < antto> given that i've been using VGA till now
2018-11-11T23:01:05 < Steffanx> So why not stick to hdmi?
2018-11-11T23:01:25 < karlp> smaller, cheaper, no downsides...
2018-11-11T23:01:48 < antto> i don't know.. HDMI kinda sounds like home-theater kind of sh*t
2018-11-11T23:02:08 < Steffanx> Lol
2018-11-11T23:02:25 < invzim> DP FTW :)
2018-11-11T23:02:50 < invzim> the new rigol is ugly as sin
2018-11-11T23:02:53 < Steffanx> Id stick to vga then antto 
2018-11-11T23:03:00 < antto> i remember reading some stuff about too black and too white is banned
2018-11-11T23:05:57 < antto> i got display port on the comput0r's built-in video card, but not on the radeon
2018-11-11T23:06:22 < karlp> dp is just hdmi without audio...
2018-11-11T23:06:49 < antto> right now, the only weird thing i see is the monitor coming kinda too slow out of suspend, and i suspect this is due to silly hdmi
2018-11-11T23:07:36 < antto> my radeon haz dvi, hdmi, and vga
2018-11-11T23:07:42 < antto> so imma get a dvi cable
2018-11-11T23:08:46 < englishman> congrats antto
2018-11-11T23:08:48 < englishman> it is a good one
2018-11-11T23:08:49 < Steffanx> Sounds like a waste of money.
2018-11-11T23:08:59 < antto> why?
2018-11-11T23:09:07 < englishman> hdmi what
2018-11-11T23:09:23 < englishman> >dp is just hdmi without audio...

2018-11-11T23:20:30 < antto> i still keep my CRT
2018-11-11T23:20:49 < Steffanx>  Not surprised.

2018-11-11T23:27:36 < mitrax> hi
2018-11-11T23:28:11 < Steffanx> Welcome mitrax
2018-11-11T23:28:17 < mitrax> well those were the shit CRT wise 20 years ago
2018-11-11T23:28:30 < Steffanx> That was before my time
2018-11-11T23:28:53 < mitrax> probably a bit longer than that, around 1995/96
2018-11-11T23:31:52 < englishman> hmm dont remember the last time i used a crt
2018-11-11T23:32:55 < Steffanx> I do. Playing Red Alert 2. Online.
2018-11-11T23:32:55 < englishman> never had that
2018-11-11T23:33:02 < englishman> went right from 286 to 486dx
2018-11-11T23:33:18 < Steffanx> The good old times.
2018-11-11T23:36:53 < Laurenceb124> Diamondtron is unironically epin
2018-11-11T23:37:00 < mitrax> my first LCDs http://download.unfiltered.net/screens02.jpg
2018-11-11T23:37:22 < Laurenceb124> but megabux modern IPS LCD is probably as good
2018-11-11T23:40:51 < Steffanx> Bad for arcade gaming
2018-11-11T23:42:19 < BrainDamage> I'm quite ok with my IPS
2018-11-11T23:42:21 < mitrax> crt: i got some dell ultrasharp 25'', but except for the higher resolution i prefered my old MVA, they had better contrast / less backlight bleeding
2018-11-11T23:42:36 < BrainDamage> then again, I'm not that anally retentive wrt displays
2018-11-11T23:48:05 < antto> i'm a hobby photographer (i guess) so it's not a bad idea to be able to see teh picture moar properly
2018-11-11T23:49:47 < Laurenceb124> CRT might still have better colour than LCD, I dunno
2018-11-11T23:50:07 < antto> it easily can
2018-11-11T23:50:53 < antto> IPS is afaik the best you can get if you're stuck with LCD.. but LCD is generally a pile of crap
2018-11-11T23:51:02 < antto> my hopes are in OLED
2018-11-11T23:53:54 < Steffanx> Can we see the photos you take online antto?

2018-11-12T01:12:20 < Laurenceb124> Anatomical penises may exist, but as pre-operative transgendered women also have anatomical penises, the penis vis-à-vis maleness is an incoherent construct
2018-11-12T01:13:01 < Laurenceb124> the penis is better understood not as an anatomical organ but as a social construct

2018-11-12T04:12:02 < Laurenceb124> so there is no way to exert net force on charged particles
2018-11-12T04:12:27 < Laurenceb124> if you use a nonlinear AC field then you might be able to make the idea work using pondermotive effect

2018-11-12T11:34:05 < zyp> dongs, that mcu shot doesn't look weird to me, apparently bottom left is ground and connected to the plate that the die is mounted on
2018-11-12T11:34:14 < dongs> yes, right
2018-11-12T11:34:30 < dongs> but that looks kinda big for mcu die
2018-11-12T11:34:44 < dongs> also why teh gnd so fat
2018-11-12T11:34:49 < zyp> you don't see the die
2018-11-12T11:34:57 < zyp> just the metal shit under it
2018-11-12T11:35:09 < dongs> ah is the die glued to it or someshit and then wirebonded on top?
2018-11-12T11:35:24 < zyp> I assume so
2018-11-12T11:35:49 < zyp> so gnd is a whole metal piece from leg all the way in under the die
2018-11-12T11:36:00 < zyp> probably helps with thermal dissipation as well
2018-11-12T11:36:19 < dongs> yeah i dont expect this ot be hot tho
2018-11-12T11:36:38 < zyp> kinda like a chip with exposed center pad, except not exposed
2018-11-12T11:36:49 < zyp> hot is relative
2018-11-12T11:36:58 < zyp> any chip that consumes power dissipates heat

2018-11-12T17:42:37 < englishman> leaf is outselling egolf 7:1 here
2018-11-12T17:42:50 < englishman> i guess the 18 month waiting list and smaller battery for more money isnt helping
2018-11-12T17:43:22 < englishman> but model 3 is selling the most now
2018-11-12T17:44:02 < englishman> not by a lot but for a car at least 2x the price, not bad

2018-11-12T17:44:42 < englishman> egolf would have been competitive if they released it here 2-3 years ago like they did in your country :p
2018-11-12T17:45:49 < zyp> egolf is not the best range for money, but it's a comfortable car to drive
2018-11-12T17:49:05 < zyp> of course, leaf is outselling everything here too
2018-11-12T17:49:25 < englishman> it didnt before, apparently, in 2015
2018-11-12T17:49:27 < zyp> all time there's 49k leaf and 31k egolf in norway
2018-11-12T17:49:30 < englishman> but the 2018 model is an actual upgrade
2018-11-12T17:49:39 < zyp> this year 14k leaf and 7k egolf
2018-11-12T17:49:49 < zyp> http://elbilstatistikk.no/ <- stats here if you wanna dig
2018-11-12T17:50:12 < zyp> looks like TMS just got overtaken by i3 for third place
2018-11-12T17:50:38 < englishman> geo blocked
2018-11-12T17:50:41 < zyp> wat
2018-11-12T17:50:46 < zyp> weird
2018-11-12T17:51:19 < englishman> nissan is trying to sell its battery division so they can buy LGs like everyone else
2018-11-12T17:51:21 < englishman> but noone is buying
2018-11-12T17:51:38 < englishman> everyone knows that leaf batteries are crap :p
2018-11-12T17:52:20 < zyp> haha, true
2018-11-12T17:52:49 < zyp> I've driven the 2018 leaf, it's nice but I still prefer my car
2018-11-12T17:52:55 < zyp> at least when disregarding range
2018-11-12T17:54:50 < zyp> oh, I also know a guy with one, met him at ikea on saturday
2018-11-12T17:55:40 < zyp> I were plugging in to charge, he laughed a bit saying he still had 85% left
2018-11-12T17:56:28 < englishman> im in the habit of just plugging in whenever its available
2018-11-12T17:56:36 < englishman> so i never think about range
2018-11-12T17:56:46 < zyp> I were making a longer trip though, not just ikea and back
2018-11-12T17:56:48 < englishman> tho everywhere i go is within 80km
2018-11-12T17:57:04 < zyp> usually when I go to ikea, I don't bother charging
2018-11-12T17:57:50 < englishman> havent been yet, but i heard the ev spots are primo
2018-11-12T17:57:57 < englishman> the one time i have been to idea, parking was the biggest issue
2018-11-12T17:58:01 < englishman> so i might actually go
2018-11-12T17:58:22 < englishman> if i needed any swedish crap, that is
2018-11-12T17:58:29 < zyp> I mostly only plug in when I need it, i.e. when it saves me a quick charge later or something
2018-11-12T17:58:37 < zyp> otherwise I don't bother

2018-11-12T17:59:13 < zyp> I prefer leaving free spots to people who need them more than me, hoping other people think the same way so there's some left for me when I need them
2018-11-12T17:59:36 < zyp> and I don't bother with paid spots when I have enough range to get home and charge cheaper
2018-11-12T18:00:04 < englishman> public EVs are pretty sparse still
2018-11-12T18:00:10 < englishman> er, EVSEs
2018-11-12T18:00:31 < zyp> that is not a problem here
2018-11-12T18:00:38 < englishman> putting them in front of all the new cannabis stores would have been smart
2018-11-12T18:00:54 < englishman> but those guys went into it 100% knowing they would have a monopoly and could do the minimum possible
2018-11-12T18:01:19 < zyp> there's tons of both free plain outlets, paid AC EVSEs and fast chargers around here within a 50km radius
2018-11-12T18:01:52 < zyp> including my local ikea
2018-11-12T18:02:04 < englishman> i have been changing my shopping habits to favour those places with evse
2018-11-12T18:02:10 < englishman> not because i use them
2018-11-12T18:02:12 < zyp> they have like 8 plain outlets, 4 22kW AC outlets and 4 50kW fast chargers
2018-11-12T18:02:14 < englishman> because what the fuck
2018-11-12T18:02:16 < karlp> what's evse mean?
2018-11-12T18:02:20 < englishman> charging station
2018-11-12T18:02:29 < karlp> yeah, I gatehred, I meant the acronym
2018-11-12T18:02:30 < englishman> electric vehicle supply equipment
2018-11-12T18:02:32 < karlp> thanks
2018-11-12T18:02:52 < englishman> went to see that freddy mercury movie
2018-11-12T18:02:56 < englishman> no evse within 4km
2018-11-12T18:02:57 < englishman> wtf
2018-11-12T18:03:02 < englishman> movies are the perfect place for them
2018-11-12T18:03:12 < zyp> basically a socket with interlocks that doesn't turn on power until a car is connected and electronics that tells the car how much current it can draw
2018-11-12T18:04:08 < englishman> we will be planning an electric trip, through some coastal countryside
2018-11-12T18:04:16 < zyp> fun
2018-11-12T18:04:18 < englishman> not many stations out there
2018-11-12T18:04:35 < englishman> a 100ft extension cord is already necessary at the ski chalet
2018-11-12T18:04:45 < zyp> you should drive over to meet up with Steffanx 
2018-11-12T18:05:08 < englishman> is the bridge open
2018-11-12T18:05:26 < karlp> hrm, speaking of, Steffanx, I'll be in boxmeer in a couple of weeks, is that any closer to you?
2018-11-12T18:05:34 < Steffanx> Lol no
2018-11-12T18:05:55 < karlp> I seem to keep visiting the parts of holland with low steffanx ratios
2018-11-12T18:06:16 < Steffanx> Yes. No one visits the nothern parts
2018-11-12T18:06:23 < Steffanx> Nothing interesting here
2018-11-12T18:06:49 < zyp> .nl is pretty small though, doesn't take that long to take a detour :p
2018-11-12T18:06:51 < karlp> oh, you're up by groningen aren't you?
2018-11-12T18:07:07 < zyp> yeah
2018-11-12T18:07:09 < Steffanx> Yessir
2018-11-12T18:07:28 < zyp> according to google maps that's only a 2:20 drive
2018-11-12T18:07:31 < karlp> hrm, boxmeer looks tiny and shitty
2018-11-12T18:07:54 < karlp> well, it's a work trip, I'm not off on a 5 hour detour to northern holland :)
2018-11-12T18:07:56 < englishman> https://www.youtube.com/watch?v=EoyFFxCtfXo
2018-11-12T18:07:59 < zyp> aww
2018-11-12T18:08:16 < zyp> well, Steffanx could make the trip :p
2018-11-12T18:08:23 < zyp> he should travel more
2018-11-12T18:08:24 < karlp> well, we'll see, I might actually be there over the weekend.
2018-11-12T18:08:30 < sync> driving over the dam at the IJsselmeer is also quite uneventful
2018-11-12T18:08:35 < sync> water on the left and water on the right
2018-11-12T18:08:42 < zyp> I did that
2018-11-12T18:09:25 < zyp> was a nice drive IMO
2018-11-12T18:09:55 < zyp> but then again, I didn't expect anything more than water on the left and water on the right :p
2018-11-12T18:10:48 < englishman> theres nothing to see in groangen, even the waffels are mail-order
2018-11-12T18:11:24 < zyp> I heard they got a nice new climbing wall there
2018-11-12T18:11:29 < zyp> Steffanx didn't tell me about that
2018-11-12T18:12:41 < zyp> hmm, according to google it's not even new

2018-11-12T19:46:43 < Steffanx> Hi lob235
2018-11-12T19:46:54 < bitmask> I designed my first pcb and its not very pretty :P
2018-11-12T19:47:08 < Steffanx> Is it in altium?
2018-11-12T19:47:09 < bitmask> but it just needs to work and its mostly just for power distribution between connectors
2018-11-12T19:47:51 < bitmask> no, I just used eagle, I started in kicad but I ran into an issue so I switched :P

2018-11-12T19:54:57 < bitmask> hmm now that I'm thinking about it, if I don't use right angle connectors I can have all the wires coming out the same side and save a lot of board space

2018-11-12T21:41:50 < karlp> bt is weird. the car will pair nicely, and if I've got google music play thing open on the phone, I can browse tracks and things.
2018-11-12T21:42:02 < karlp> don't hve the app open, no browse.
2018-11-12T21:42:18 < karlp> but even though it puts up a touchable seek bar, I can't seek from teh car screen
2018-11-12T21:52:48 < Steffanx> Lol. jpa- 
2018-11-12T21:56:53 < Steffanx> Awh. The Stan Lee is dead. Marvel movies will never be the same again.

2018-11-12T22:17:55 < Steffanx> Atmel ICE?
2018-11-12T22:17:59 < kakimir> k
2018-11-12T22:18:18 < kakimir> and think about it
2018-11-12T22:18:25 < kakimir> it needs only reset pin
2018-11-12T22:18:38 < kakimir> and vtg and gnd
2018-11-12T22:18:45 < Steffanx> updi much?
2018-11-12T22:18:51 < kakimir> no
2018-11-12T22:18:55 < kakimir> dW
2018-11-12T22:19:37 < Steffanx> UPDI is fucked up. It uses the reset pin.
2018-11-12T22:19:45 < Steffanx> and when updi is enable the reset pin does not work as reset
2018-11-12T22:20:03 < Steffanx> you can disable it using fuses and make it a gpio or reset.
2018-11-12T22:20:13 < Steffanx> to re-enable updi you have to use some 12V pulse.
2018-11-12T22:20:30 < Steffanx> The standard tools of Microchip/Atmel cant even do that -_-
2018-11-12T22:21:23 < Steffanx> and always nice to do that in-circuit. 
2018-11-12T22:23:01 < Steffanx> </avr story>
2018-11-12T22:23:31 < kakimir> with dW you cannot program fuses
2018-11-12T22:23:42 < kakimir> but you enable dW with fuse
2018-11-12T22:24:58 < Steffanx> and you still need the spi stuff to do that
2018-11-12T22:25:09 < Steffanx> updi is the only interface available for stuff like 1617
2018-11-12T22:41:24 < englishman> does the housewarming have to be in winter
2018-11-12T22:41:46 < englishman> i dont think i would like to travel from a dark place to a darker place
2018-11-12T22:42:49 < Steffanx> is there are darker place then your basement?
2018-11-12T22:43:23 < englishman> the basement is not very dark, that is where the grow lights are
2018-11-12T22:43:38 < Steffanx> ah ofcourse
2018-11-12T22:46:57 < con3> Anyone here experienced anything where the code is just stuck at the first temp breakpoint at main?
2018-11-12T22:49:46 < con3> Cracki: yes, uhm an stm32f7. But I've erased the flash with the st link and I have data cache disabled, but instruction cache enabled
2018-11-12T22:49:55 < con3> nothing has really changed on the code..
2018-11-12T22:50:03 < con3> which is weird..
2018-11-12T22:50:38 < con3> damn, I'll disable quick and try again. One sec!
2018-11-12T22:53:12 < con3> Cracki: that worked, I don't know why... but that worked ¯\_(ツ)_/¯

2018-11-13T10:29:02 < Sadale> good enough for hobbyist, low-power use.
2018-11-13T10:29:31 < Sadale> I mainly want to use it for studying the behavior of a charge pump under different input voltage.
2018-11-13T10:29:47 < Sadale> lol true
2018-11-13T10:29:51 < Sadale> right. Just get the right tool to do the job.

2018-11-13T10:37:26 < cjbaird> Pretty-much state-of-the-art in CW kits. Its specs wipe the floor with regular NE602/612-based designs. Going better would need a SDR rig.

2018-11-13T11:22:52 < karlp> if you were mounting these modules, would you put surface mount pads underneath? or holes?
2018-11-13T11:23:12 < karlp> I threw holes in, but i'm kinda thinking that just pads would probably be easier to solder,
2018-11-13T11:23:27 < karlp> just place down and poke solder in, no worries about it leaking out the bottom hole or anything

2018-11-13T13:07:43 < cjbaird> jadew: it's got the 40m lowpass filter, what everyone else w/ a QCX at the local club has. 7023kHz being the centre of activity.

2018-11-13T20:52:04 < antto> wow, ur overcomplicating things
2018-11-13T20:52:14 < antto> USB from comput0r into monit0r
2018-11-13T20:53:04 < antto> and DVI ;P~
2018-11-13T20:54:00 < englishman> card readers are at least 20 years old so lunix might have support for them built in now
2018-11-13T20:54:00 < antto> well, monitor says USB 3.0, my comput0r iz USB 2 afaik
2018-11-13T20:54:51 < antto> the monitor also talks about a CD with fancy drivers (which i don't have since i bought it "used" from a store)
2018-11-13T20:56:07 < antto> yeah, but i also bought the sketchiest USB A->B cable i found ;P~
2018-11-13T20:56:49 < antto> doesn't matter, it works, and i even think the monitor reads the card faster than the silly card reader i used
2018-11-13T20:57:02 < antto> ++achievements;
2018-11-13T20:57:04 < antto> \o/

2018-11-14T07:48:41 < ds2> ethernet would be nice
2018-11-14T07:48:58 < ds2> trying to figure a simple sensor thingie and I don't want to deal with ESP32's

2018-11-14T07:49:31 < qyx> even tls is easy with wolfssl
2018-11-14T07:49:42 < qyx> and using wolfmqtt for mqtt, that was moderately easy
2018-11-14T07:49:50 < qyx> there was some debugging needed
2018-11-14T07:49:55 < ds2> yes but then you need to throw in sockets and things
2018-11-14T07:50:06 < dongs> ESP1488
2018-11-14T07:50:17 < ds2> silabs wireless geckos have a brain dead IP interface
2018-11-14T07:50:21 < ds2> something like that 
2018-11-14T07:50:28 < dongs> try wiznet shit then?
2018-11-14T07:50:30 < dongs> if youre lazy
2018-11-14T07:50:34 < dongs> i heard that has an IP stack on it
2018-11-14T07:50:37 < ds2> that's HW isn't it?
2018-11-14T07:50:43 < dongs> yes, but thats waht you want isnt it?
2018-11-14T07:50:48 < qyx> now I am using wolfmqtt over hw sockets in a quectel module
2018-11-14T07:50:48 < dongs> more lazy, just add hardware
2018-11-14T07:50:53 < ds2> no, I want a library that does that
2018-11-14T07:50:55 < dongs> rip

2018-11-14T12:41:11 < zyp> only problem with this sort of fun is that it's fun when I do one, not so fun when I need to do like ten
2018-11-14T12:41:59 < zyp> but I'll put the other ones off for later, wanna test this first
2018-11-14T12:42:07 < zyp> what's an ST chip?
2018-11-14T12:42:16 < PaulFertser> The wires are so thick, do they need to pass much current?
2018-11-14T12:42:22 < zyp> the one I added is a CAN transceiver
2018-11-14T12:42:27 < zyp> PaulFertser, no
2018-11-14T12:43:01 < zyp> this is still scrap cat5, just like last time people commented on them being thick :p

2018-11-14T12:46:05 < zyp> the two isolated ones could probably be thinner, but then I need to search for thinner wire
2018-11-14T12:47:31 < zyp> the two boards here is part of the same system, first board (that I modified today) didn't have CAN designed in, just the signals ready on test points in case they might be needed
2018-11-14T12:47:55 < zyp> the second board got CAN, but the designer fucked up the pinout of the chip
2018-11-14T12:48:20 < zyp> so now I get to modify all prototypes of both

2018-11-14T12:54:34 < karlp> is that a socketed mini fuse lower left of the transceiver you added?
2018-11-14T12:54:41 < zyp> yes
2018-11-14T12:54:42 < PaulFertser> We had a board where there was a similar fuckup for an SDRAM chip. The rework looked "epic", but worked nicely (performed by some professional soldering girl).
2018-11-14T12:54:58 < karlp> like, a "burn out and needs replacing" fuse? what size?!
2018-11-14T12:55:10 < zyp> 100mA
2018-11-14T12:56:01 < karlp> what's that protecting? well out of my niche.
2018-11-14T12:56:08 < karlp> can't you get ptc things for that sort of rating?
2018-11-14T12:56:14 < karlp> or are they not fast enough?
2018-11-14T12:56:21 < zyp> dunno, I didn't design it
2018-11-14T12:56:30 < zyp> I just specced what I wanted
2018-11-14T12:57:35 < zyp> the whole circuitry in that area is related to an external "service" connector, the fuse protects the power out through that
2018-11-14T12:59:37 < zyp> it's not supposed to power much, either just one side of digital isolators in the connected cable, or maybe a simple mcu connected to a button panel

2018-11-14T15:33:01 < jpa-> let's play portability guessing game: how likely would you consider a platform to have sizeof(bool) >= 8?
2018-11-14T15:33:49 < karlp> heh,
2018-11-14T15:34:00 < karlp> even on x64 I would have still expected 4?
2018-11-14T15:34:57 < jpa-> yeah, i've never seen larger than 4
2018-11-14T15:35:28 < karlp> it's 1 on my x64 laptop.
2018-11-14T15:35:34 < karlp> where did you find it at 8?
2018-11-14T15:35:55 < jpa-> i didn't, but i'm considering allocating only 3 bits to a field that stores sizeof(bool)
2018-11-14T15:36:12  * karlp laughs
2018-11-14T15:36:18 < karlp> 3 bits is more than enough for anyeone.
2018-11-14T15:36:23 < jpa-> great :P
2018-11-14T15:36:52 < jpa-> in case of overflows i do have a fallback format with 16 bits reserved for it, i guess that will be enough atleast :D

2018-11-14T15:39:10 < karlp> just wondering how much of a pain it is for manufacturing to have to put boards together where the "connector" i sjust a row of holes.
2018-11-14T15:39:23 < karlp> seems like an invitation to hand soldering.
2018-11-14T15:40:49 < jpa-> i have been involved in one product where TFT display was mounted with headers.. manufacturing didn't complain and price didn't seem much different than SMD-only projects
2018-11-14T15:40:57 < jpa-> but that was small volumes (~10pcs)
2018-11-14T15:41:20 < jpa-> i can tell however that it was very painful to remove that when i had to debug a problem hiding between the boards :P

2018-11-14T15:43:45 < jpa-> that could easily bounce it to higher than 8
2018-11-14T15:43:49 < zyp> maybe you could store n where sizeof(bool) is 2**n
2018-11-14T15:44:25 < jpa-> yeah, but that is difficult to compute so that C regards it as a constant value

2018-11-14T16:56:39 < mawk> the battery lasts a while, it's silent
2018-11-14T16:56:50 < mawk> and it makes cool light when you approach your hands
2018-11-14T16:58:28 < zyp> K800 looks inconvenient
2018-11-14T16:58:50 < zyp> wired it'd probably be fine, but it doesn't look very useful as a wireless keyboard
2018-11-14T16:59:46 < mawk> I like numpads
2018-11-14T17:00:22 < zyp> I mean, IMO the point of a wireless keyboard is that it's easy to bring around, like when you sit on the couch with your computer hooked to the tv
2018-11-14T17:00:23 < englishman> cant live without it
2018-11-14T17:00:33 < englishman> hence, the amazon link

2018-11-14T17:05:24 < zyp> you either need a bigger desk or you really need to clean it

2018-11-14T17:09:44 < englishman> they have been eol over a year
2018-11-14T17:10:09 < day> englishman: what do the edisons do that makes them irreplaceable for you?
2018-11-14T17:10:09 < mawk> I'm in a tiny appartment
2018-11-14T17:10:15 < mawk> I have like 0.5m² of desk
2018-11-14T17:10:27 < englishman> I think I will redesign the project for Artik, but not tell the client until they finally realize there are no more Edisons. then sell them the design at the last minute for 100k
2018-11-14T17:10:47 < englishman> day: they are in an existing design
2018-11-14T17:11:06 < aandrew> That sucks, I am thankful I lol’d when intel though they were going to take on the Arduinos and rpi/bbbs of the world
2018-11-14T17:11:12 < englishman> and they " don't have the budget" to respin
2018-11-14T17:11:32 < englishman> soon they won't have any budget at all with zero hardware
2018-11-14T17:11:49 < aandrew> englishman: that’s a great idea. Most engineers have no concept of “don’t leave money on the table”
2018-11-14T17:12:06 < englishman> that's why I don't do business with Samtec
2018-11-14T17:12:18 < englishman> fuck samtec
2018-11-14T17:12:26 < day> i liked edison because they made some ble examples based on BlueZ. which i found nowhere else
2018-11-14T17:12:44 < englishman> also Edison failed FCC with onboard wifi antenna
2018-11-14T17:12:58 < aandrew> I use them for a few specific connectors but try to stick with molex, hirose and ... another that escapes me atm
2018-11-14T17:13:44 < aandrew> Bluez is such a terrible stack to work with

2018-11-14T21:14:34 < kakimir> i don't use signed values but for temperature
2018-11-14T21:14:56 < kakimir> you know I stop charging for 5ms for idle voltage reads
2018-11-14T21:15:00 < kakimir> every second
2018-11-14T21:16:12 < kakimir> just enough
2018-11-14T21:16:28 < kakimir> it at least gets rid of ohmic shiet
2018-11-14T21:16:47 < kakimir> also sampling is done always same time after suspend
2018-11-14T21:17:36 < kakimir> why
2018-11-14T21:17:49 < kakimir> mine works without issues
2018-11-14T21:21:54 < kakimir> but I figured it out
2018-11-14T21:22:10 < kakimir> I do deltaU weighted averaging between periods
2018-11-14T21:24:22 < kakimir> that should settle it down in right range
2018-11-14T21:24:33 < kakimir> soon I average everything but my ADC samples
2018-11-14T21:24:46 < kakimir> literally samples are just single conversion!
2018-11-14T21:25:21 < kakimir> even low pass filtering is done 15cm away from ADC pin

2018-11-14T21:39:24 < kakimir> tip: add 4 levels of filtering
2018-11-14T21:40:40 < Steffanx> ty
2018-11-14T21:49:15 < kakimir> maybe even 1:4 weight of averaging old:new would do it
2018-11-14T21:49:34 < kakimir> after all it's just about getting 15 to look like 14
2018-11-14T21:50:01 < kakimir> while 15 is pretty generous threshold
2018-11-14T21:53:58 < kakimir> hello fucker
2018-11-14T21:56:48 < kakimir> yes
2018-11-14T21:56:57 < kakimir> 4 levels of filtering makes it work

2018-11-14T22:01:13 < jpa-> multiple levels of filtering is nice in that it approaches a gaussian filter
2018-11-14T22:02:10 < jpa-> with a smooth frequency response; compared with e.g. exponential average or sliding window average which have much weirder frequency response
2018-11-14T22:04:20 < jpa-> (well exponential average also has smooth response but the falloff is quite slow)

2018-11-15T01:07:50 < aandrew> ahh
2018-11-15T01:08:03 < aandrew> how did it go?
2018-11-15T01:08:23 < englishman> great
2018-11-15T01:08:26 < englishman> should have asked for more money
2018-11-15T01:08:39 < englishman> otherwise, everything went well
2018-11-15T01:09:07 < aandrew> you gonna be pumpin for the man soon?
2018-11-15T01:13:08 < englishman> we'll see

2018-11-15T01:41:34 < aandrew> that's practically a full time job
2018-11-15T01:42:10 < zyp> if I had a p&p I'd probably put it in the shed, or whatever the external storage room would be called in english
2018-11-15T01:42:35 < zyp> planning to use that as a workshop anyway
2018-11-15T01:43:31 < aandrew> heh I don't know if a single assembly house has a current website
2018-11-15T01:43:47 < englishman> i dont
2018-11-15T01:43:48 < englishman> :p
2018-11-15T01:44:27 < aandrew> you can't put a pnp in an outside shed 
2018-11-15T01:45:35 < aandrew> it needs good stable environment, maintained temp and humidity
2018-11-15T01:45:36 < sync> aandrew: the panasonic system united uses also gives you DNS
2018-11-15T01:46:12 < sync> well you can put it in an outside shed
2018-11-15T01:46:17 < zyp> aandrew, of course
2018-11-15T01:46:22 < sync> ours sat in a shed forever
2018-11-15T01:46:29 < aandrew> sync: this does too but allows external requests
2018-11-15T01:46:47 < sync> it was annoying as fuck because we had to warm up the vision card with a heat gun if it got below 0°C
2018-11-15T01:46:54 < sync> yeah, same with the thing united used
2018-11-15T01:47:44 < zyp> shed might not be the best word, but I'm talking about the storage room in between the two houses here: https://bin.jvnv.net/file/FVANz.jpg
2018-11-15T01:48:18 < englishman> actually IPC norms only state temp and humidity should be in a certain range for operator comfort
2018-11-15T01:48:34 < englishman> if it throws off your calibrations, that's your own problem
2018-11-15T01:49:06 < sync> yeah your yield goes down but that is not their problem
2018-11-15T01:49:10 < englishman> the euroshed
2018-11-15T01:49:12 < zyp> I'm planning to use it partly as a workshop, so I've been thinking about insulating it
2018-11-15T01:49:50 < kakimir> kakitips: if your adc resolution is not enought, add noise to averaging
2018-11-15T01:50:00 < aandrew> englishman: lots of packages require humidity to be within a range or you have to bake the shit or it can pop
2018-11-15T01:50:02 < zyp> and just the residual heat from shit in there will probably keep temperature reasonable enough
2018-11-15T01:50:40 < englishman> only for storage
2018-11-15T01:51:13 < englishman> yes get a three phase oven in there
2018-11-15T01:51:40 < zyp> originally I were planning to put a server rack there too, but it seems like I end up with a nice spot under the stairs where I can tuck away a rack on wheels
2018-11-15T01:52:10 < Lux> yeah i killed quite a few ws2812 leds due to them popping in reflow
2018-11-15T01:52:19 < zyp> (I ran double network conduit to both spots and will run fiber to both as well, just in case)
2018-11-15T01:52:51 < Lux> even had visible cracks
2018-11-15T01:53:22 < zyp> englishman, yeah, I specced I wanted a subpanel there with 22kW capacity, so there's plenty of power for an oven
2018-11-15T01:53:47 < zyp> nevermind that the house gets like 28kW total :p
2018-11-15T01:54:05 < englishman> wot
2018-11-15T01:54:25 < englishman> all your 3⌀ technology and you get just 28kW
2018-11-15T01:54:33 < englishman> our furnace is 23kW
2018-11-15T01:54:53 < sync> my ondemand water heater is 25kW
2018-11-15T01:54:56 < sync> for whatever reason
2018-11-15T01:55:00 < englishman> to heat water
2018-11-15T01:55:02 < englishman> is the reason
2018-11-15T01:55:11 < sync> it could be a lot smaller to do that
2018-11-15T01:55:22 < englishman> is it a whole house on demand heater
2018-11-15T01:55:34 < englishman> idk if i would want it to be smaller
2018-11-15T01:56:11 < englishman> start adding it up
2018-11-15T01:56:15 < englishman> 12kW to charge two cars
2018-11-15T01:56:17 < englishman> 4.5kW oven
2018-11-15T01:56:21 < englishman> 5.5kW hot tub
2018-11-15T01:56:27 < sync> it is for the whole flat, yes
2018-11-15T01:56:34 < englishman> not much left in 28kW to heat the house and run servers
2018-11-15T01:56:36 < sync> so a kitchen + a bathroom
2018-11-15T01:59:43 < zyp> 28 kW is plenty

2018-11-15T02:15:50 < Laurenceb124> zyp: so, who cares?
2018-11-15T02:15:54 < sync> like they did with businesses before
2018-11-15T02:15:55 < Laurenceb124> Norway has hydropower
2018-11-15T02:16:27 < kakimir> my ADC has LSB resolution of 5mV, I convert ADC result into voltage by measuring also bandgap.. how to avoid resulting voltage incrementing in these steps?
2018-11-15T02:16:29 < Laurenceb124> guy at wurk is 3d printing a vangena now
2018-11-15T02:16:37 < Laurenceb124> babby is going to get born soon
2018-11-15T02:16:52 < kakimir> I want resolution more closer to 1mV
2018-11-15T02:16:58 < Laurenceb124> we will case a vanginnaaa out of silicone using the mould
2018-11-15T02:17:03 < sync> get a non shit ADC
2018-11-15T02:17:07 < zyp> Laurenceb124, well, yeah, the matter here isn't really power production, it's grid capacity
2018-11-15T02:17:27 < Laurenceb124> stm32 is pretty decent
2018-11-15T02:17:30 < Laurenceb124> adc wise
2018-11-15T02:17:35 < kakimir> could I drive ADC pin with gpio pin and alter it's value slightly
2018-11-15T02:17:46 < kakimir> then sample it
2018-11-15T02:18:01 < Laurenceb124> heath robinson approves
2018-11-15T02:18:19 < zyp> grid needs to handle peak, and therefore it's argued that consumers with higher peak usage should pay more than consumers with less peak usage
2018-11-15T02:18:39 < kakimir> sure
2018-11-15T02:19:16 < Laurenceb124> in a few days I might have video of babby being "born"
2018-11-15T02:19:56 < englishman> above 50kW here there is a power fee and an energy fee
2018-11-15T02:19:59 < kakimir> Laurenceb124?
2018-11-15T02:20:00 < Laurenceb124> >3d printed vagoo gives birth to the babby
2018-11-15T02:20:02 < englishman> but below that, no power fee
2018-11-15T02:20:05 < Laurenceb124> >babby gets shakkken
2018-11-15T02:20:10 < Laurenceb124> its gunna be cool
2018-11-15T02:20:21 < Laurenceb124> typical uk tv https://postimg.cc/MXVQcq7s
2018-11-15T02:20:24 < kakimir> you keep the vagoo artifact?
2018-11-15T02:20:28 < zyp> here it still depends on the power companies
2018-11-15T02:20:35 < englishman> maybe in a place with lots of non-hydro renewables it becomes a problem
2018-11-15T02:21:17 < zyp> but it's likely that they all will introduce grid fee based on peak power, now that everybody got smart meters
2018-11-15T02:21:31 < Laurenceb124> kakimir: dunno atm
2018-11-15T02:21:57 < kakimir> for "research"
2018-11-15T02:22:02 < Laurenceb124> keeek
2018-11-15T02:22:11 < Laurenceb124> ok uk is now more weird than nippon land
2018-11-15T02:22:12 < zyp> (smart meters here are mandatory starting 2019-01-01)
2018-11-15T02:22:17 < Laurenceb124> https://postimg.cc/yWmD1nKt
2018-11-15T02:22:27 < Laurenceb124> wew mandatory smart meters
2018-11-15T02:22:41 < kakimir> Laurenceb124: next level
2018-11-15T02:22:43 < zyp> my impression is that pretty much everybody got them already
2018-11-15T02:23:00 < englishman> in 1st world countries sure
2018-11-15T02:23:07 < englishman> but we're talking about britain here
2018-11-15T02:23:10 < zyp> everybody in norway*
2018-11-15T02:23:34 < zyp> uk probably still have those coin operated meters
2018-11-15T02:23:48 < Laurenceb124> lul unironically true
2018-11-15T02:23:48 < kakimir> in here even abaddoned house has remote readable meter

2018-11-15T02:24:11 < Laurenceb124> lulwut
2018-11-15T02:24:25 < sync> interesting zyp
2018-11-15T02:24:43 < sync> here you are not required to have them if you use less than a certain amount of energy
2018-11-15T02:24:44 < kakimir> I have been in house where remote readable meter says 0kwh and has been there for years
2018-11-15T02:25:09 < zyp> remote readable doesn't equal smart
2018-11-15T02:25:36 < kakimir> waa
2018-11-15T02:25:48 < zyp> all the meters I were installing when I were working as an electrician over ten years ago were remote readable
2018-11-15T02:26:01 < Laurenceb124> https://postimg.cc/jDmfw5FF
2018-11-15T02:26:12 < sync> yeah, most of the smart meters they put in there are not remote readable
2018-11-15T02:26:21 < Laurenceb124> in uk we used to have electrolytic meters until recently
2018-11-15T02:26:23 < sync> due to some uproar about privacy
2018-11-15T02:27:01 < zyp> I think the main difference between the old «remote readable» stuff and the new «smart» stuff is the data rate
2018-11-15T02:27:16 < Laurenceb124> my heating system was installed in 1930s
2018-11-15T02:27:24 < Laurenceb124> if its not broken dont fix :P
2018-11-15T02:27:44 < englishman> some people didnt want to upgrade to smart meters here
2018-11-15T02:27:47 < englishman> so they got their shit disconnected

2018-11-15T02:28:02 < Laurenceb124> my sides wtf
2018-11-15T02:28:19 < Laurenceb124> >Bullet club
2018-11-15T02:28:23 < zyp> «my smart meter is making me sick»
2018-11-15T02:28:25 < zyp> etc
2018-11-15T02:28:30 < kakimir> have you ever added noise to your samples Laurenceb124 
2018-11-15T02:28:49 < kakimir> in order to archive something
2018-11-15T02:28:58 < sync> "upgrade" englishman
2018-11-15T02:29:13 < Laurenceb124> kakimir: no I just clocked the adc faster
2018-11-15T02:29:24 < englishman> needle meters belong in the 60s
2018-11-15T02:29:44 < sync> nah, they at least measure apparent loads correctly
2018-11-15T02:29:54 < aandrew> kakimir: I want to experiment with dithering 
2018-11-15T02:30:00 < Laurenceb124> englishman: kek needle meters are new in uk
2018-11-15T02:30:08 < aandrew> but doesn't the sampling system have to know the noise you're adding
2018-11-15T02:30:39 < zyp> apparently the power authority have said that people can be exempt from the smart meters if they got a doctor's note stating that it's giving them health problem, and the medical authority have replied that doctors can't give notes for that since they have no scientific basis
2018-11-15T02:30:43 < kakimir> you can add noise by clocking adc too fast?
2018-11-15T02:30:47 < englishman> hahaha
2018-11-15T02:33:20 < sync> my grandma had one installed, they changed it back to a ferranti one after it blew up like three times in a row

2018-11-15T02:34:40 -!- Hamilton [~Hamilton@unaffiliated/hamilton] has joined ##stm32
2018-11-15T02:34:43 < kakimir> noise + averaging = more than adc resolution resolution
2018-11-15T02:36:10 < aandrew> kakimir: so it's just the averaging that gets you sub-sb results, not some kind of correlated processing?
2018-11-15T02:36:11 < sync> but that is a common problem there, at least one device per year dies during at thunderstorm
2018-11-15T02:37:14 < karlp> heh, created footprint outline dxf from y-negative view of a 3d model from phoenix.
2018-11-15T02:37:20 < karlp> worked great for a symmetric part
2018-11-15T02:37:24 < karlp> then an offset part,
2018-11-15T02:37:37 < karlp> didn't realize till later that y-negatiev (duh) was from the bottom :)
2018-11-15T02:37:43 < karlp> so it's mirrored :)
2018-11-15T02:38:12 < aandrew> sub-lsb
2018-11-15T02:38:18 -!- Hamilton [~Hamilton@unaffiliated/hamilton] has left ##stm32 ["WeeChat 2.3"]
2018-11-15T02:40:31 < kakimir> yes sub-lsb
2018-11-15T02:46:20 < aandrew> kakimir: no I understand thetheory with averaging, but thought that if you correlated the noise with processing you could do even better
2018-11-15T02:53:04 < Laurenceb124> I've got to ~18enob with f103
2018-11-15T02:54:25 < Laurenceb124> outputting at 62hz
2018-11-15T02:54:48 < aandrew> Laurenceb124: wow, any tricks you'd be willing to share?
2018-11-15T02:55:34 < Laurenceb124> just run adc at fastest speed poss and use dma, then write processing dsp in asm
2018-11-15T02:55:43 < Laurenceb124> its not too hard
2018-11-15T02:57:01 < Laurenceb124> more power hungry than sigma delta adc on F3, but about the same performance or maybe a bit better even
2018-11-15T02:57:01 < aandrew> "write processing dsp in asm" sounds like the glossed-over part
2018-11-15T02:57:05 < Laurenceb124> heh
2018-11-15T02:57:26 < Laurenceb124> mine was application specific, bandpass and decimation in one step
2018-11-15T02:57:33 < Laurenceb124> not very useful for others
2018-11-15T02:58:09 < Laurenceb124> at 1Msps its challenging to keep up with the adc
2018-11-15T02:59:18 < Laurenceb124> actually its better than F3 arguably, as you can decode to 18enob when you arent interested in DC
2018-11-15T02:59:58 < kakimir> what is enob?
2018-11-15T03:00:03 < Laurenceb124> e.g. zero IQ receiver architecture when final demodulation is DSP centered around a few hundred khz
2018-11-15T03:00:10 < Laurenceb124> effective number of bits
2018-11-15T03:00:25 < aandrew> driving the ADC with a strong source would be important, any input filtering what processing were you doing, just averaging? what was vref?
2018-11-15T03:00:25 < Laurenceb124> F3 sigma delta could never work for what I was doing
2018-11-15T03:00:49 < Laurenceb124> vref was 3.3v with filtering
2018-11-15T03:01:00 < Laurenceb124> all the analogue side of the processor was on a dedicated supply
2018-11-15T03:01:36 < Laurenceb124> filtering was some standard IIR stuff using powers of two for all the coefficients and thumb2 asm
2018-11-15T03:02:09 < aandrew> gotcha
2018-11-15T03:02:25 < Laurenceb124> on F1 and F4 (only processors I've taken adc to the limit on), dedicated analogue supply was needed to get max performance
2018-11-15T03:02:39 < Laurenceb124> early F4 adc was total shit but never ones seem ok
2018-11-15T03:03:19 < aandrew> I have been meaning ot learn basic filtering and demod (digitally) for a while
2018-11-15T03:03:30 < aandrew> just no time
2018-11-15T03:03:33 < Laurenceb124> I was using a proper PMIC, when I screwed it up so digital was on, but no analogue supply, stm32 wouldnt start up
2018-11-15T03:03:40 < Laurenceb124> but it didnt seem to be damaged
2018-11-15T03:04:41 < aandrew> and poor math skillz
2018-11-15T03:05:20 < Laurenceb124> I wrote an optimiser in matlab to design my filter
2018-11-15T03:05:35 < Laurenceb124> so it would work using fixed point with powers of two for almost everything
2018-11-15T03:06:25 < Laurenceb124> hmm I just thought
2018-11-15T03:06:46 < Laurenceb124> with faster stm32 like F7 I could probably do complete GPS receiver like this
2018-11-15T03:07:01 < Laurenceb124> no need for one of the rf front ends with adc
2018-11-15T03:07:19 < Laurenceb124> F4 is fast enough to do software gps
2018-11-15T03:07:52 < Laurenceb124> just F7 + one of the dvbt dongle ICs
2018-11-15T03:09:48 < aandrew> nice. I might have to pick your brains until you /ignore me at some point
2018-11-15T03:10:55 < Laurenceb124> more interesting than my day jerb
2018-11-15T03:11:03 < Laurenceb124> but anything is more interesting than that
2018-11-15T03:11:16 < Laurenceb124> atm I'm writing CE documentation for babbyshake monitor
2018-11-15T03:12:59 < aandrew> I worked with another contractor who had a woodcut of a little boy outside of an outhouse grabbing toilet paper

2018-11-15T03:14:53 < Laurenceb124> the guy pulling the baby manikin out of the 3d fleshlight is very distracting
2018-11-15T03:19:05 < karlp> man, 3d modelling is addictive :)
2018-11-15T03:19:42 < Laurenceb124> depends what ur modelling ... :P
2018-11-15T03:19:56 < Laurenceb124> and if you can print it in silicone rubber
2018-11-15T03:19:58 < karlp> yeah, I'm just doing basic fit and view.

2018-11-15T03:39:53 < karlp> anyway, way late.
2018-11-15T03:40:47 < karlp> englishman: if only phoenix was as good at saying "these parts all mate with this part" like samtec does
2018-11-15T03:40:56 < karlp> seems to be "go find it yourself" for phoenix
2018-11-15T03:44:36 < dongs> how the fuck does 8bit parallel interface work when you have only one A0 line and D0..D7, RD/WR/CS
2018-11-15T03:44:51 < dongs> like, how do you select address
2018-11-15T03:45:41 < Ultrasauce> there's an address latch, you use the data lines to set it
2018-11-15T03:45:58 < dongs> what would it be called
2018-11-15T03:46:24 < dongs> there's only A0, D0..D7, CS, RD, WR and IRQ (output)
2018-11-15T03:47:51 < dongs> looks like maybe A0 is that.
2018-11-15T03:48:20 < dongs> A0 goes low, D0..7 sets address, then WR toggles low/high

2018-11-15T12:58:27 < Hamilton> Was there ever a language that had the same amount of *hype* (for lack of a better word) of Rust but then couldn't gain traction? It's not just hype though...Some tools writtein in Rust like ripgrep, fd are faster than their C counterparts (ag/grep and find)...I'm in the awkward position of halfway learning C and seeing the hype about Rust

2018-11-15T12:59:11 < Hamilton> I'm saying, look C programs had like 20 years to use concurrency and stuff...but somehow young Rust programs manage to comepte with that

2018-11-15T13:21:22 < Ecco> :-D
2018-11-15T13:22:22 < karlp> fucking rasppi shits.
2018-11-15T13:22:26 < karlp> lets make a cheaper smaller one,
2018-11-15T13:22:41 < karlp> keeps full size hdmi, and a camera connector, drops ethernet
2018-11-15T13:23:15 < dongs> go ahead. just pay e14 for engineering change and order 5k
2018-11-15T13:23:26 < dongs> they run a pro cloner service there.
2018-11-15T13:23:39 < karlp> fuck that
2018-11-15T13:23:40 < dongs> https://www.element14.com/community/docs/DOC-76955/l/raspberry-pi-customization-service
2018-11-15T13:23:59 < karlp> more interested in talking to chian about customizing an allwinning design
2018-11-15T13:24:05 < dongs> ah yes sure
2018-11-15T13:24:25 < dongs> i thoguth you had to stick with the retarded broadScum SoC
2018-11-15T13:24:56 < karlp> no, was ust looking at this new rpi 3a+ thing they annouced today
2018-11-15T13:25:39 < qyx> I played a bit with that SMA5D27 SOM recently
2018-11-15T13:25:48 < qyx> *SAMA5D27
2018-11-15T13:26:14 < qyx> it looks decent
2018-11-15T13:26:23 < qyx> it is a 40x38mm SOM
2018-11-15T13:26:29 < dongs> yeah it is nice.
2018-11-15T13:39:18 < zyp> karlp, to be fair, the usb hub/ethernet chip probably costs more than the hdmi/camera connectors
2018-11-15T13:39:53 < zyp> both hdmi and camera shits are just hooked to the SoC, dropping them only saves the connector
2018-11-15T13:39:59 < zyp> unlike ethernet
2018-11-15T13:42:17 < karlp> Haohmaru: olimex modules? never heard of them...
2018-11-15T13:42:29 < karlp> 40x38 and all these squares are no good...
2018-11-15T13:42:43 < zyp> karlp, what's your goal?
2018-11-15T13:42:58 < karlp> 2 din rail units wide or better.
2018-11-15T13:43:18 < karlp> square modules have to go vertical and that changes assembly and where you can put things, and which cases you can use.
2018-11-15T13:43:35 < zyp> ah, working on a new gateway thing?
2018-11-15T13:43:44 < karlp> yar, just for fun at the moment though
2018-11-15T13:43:59 < karlp> it woudl be a whole new category of device vs these router platforms
2018-11-15T13:44:31 < karlp> there's newer versions of what we've got, but they're not really very exciting, just "a bit better, a bit faster, a bit newer"
2018-11-15T13:45:50 < karlp> it's _almost_ tempting to see how insane it would be to route one myself, given that I can throw out a pile of balls for cameras and hdmi and rgmii and audio and shit :)
2018-11-15T13:46:01 < karlp> but I know I'd never hve time for it really :)
2018-11-15T13:46:10 < zyp> I've been tempted to roll a board with an allwinner h5
2018-11-15T13:46:53 < zyp> like the orange pi stuff
2018-11-15T13:47:23 < zyp> seems supported enough without too much hassle, hardware looks fairly easy to do
2018-11-15T13:47:58 < karlp> yeah, h3/h5 would be fne for me.
2018-11-15T13:48:17 < karlp> I'd consider v3s, as it includes ram in package and things, but it's really a bit too small, not enough gain vs the current platforms.
2018-11-15T13:48:26 < karlp> h2+ even, which is just cutdown h3.
2018-11-15T13:48:36 < karlp> gonna finish protos first anyway :)

2018-11-15T14:29:36 < qyx> I am trying to find some power consumption figures
2018-11-15T14:30:15 < Sadale> wow what? $49 a module?
2018-11-15T14:30:17 < Sadale> That's expensive
2018-11-15T14:30:29 < zyp> compared to what?
2018-11-15T14:30:36 < Sadale> The specs is good, tho
2018-11-15T14:31:13 < qyx> yeah, if a single connector is used, it is ok
2018-11-15T14:31:17 < qyx> but there are two
2018-11-15T14:32:02 < Sadale> What's wrong with two connectors?
2018-11-15T14:32:27 < qyx> the thing Haohmaru says

2018-11-15T14:32:36 < Sadale> I see. mre easy to misalign.
2018-11-15T14:32:40 < karlp> I think I even suggested it to english for his edison.
2018-11-15T14:32:40 < Sadale> more likely*
2018-11-15T14:32:53 < zyp> karlp, cool, didn't see that
2018-11-15T14:33:23 < karlp> qyx: no can. present gateway is rs485/wifi/ethernet in 2 din rail units 
2018-11-15T14:33:27 < qyx> all current consumption is TBD
2018-11-15T14:33:38 < qyx> karlp: :(
2018-11-15T14:33:48 < karlp> what devices do yo uhave in din rails that speak can? :)
2018-11-15T14:34:01 < qyx> I plan to have some
2018-11-15T14:34:03 < karlp> modbus/profi/blah
2018-11-15T14:34:08 < qyx> but for now only modbus
2018-11-15T14:34:08 < zyp> it's a bit annoying that they don't have onboard core power reg
2018-11-15T14:34:10 < karlp> but nothing out there is can on dinrails
2018-11-15T14:34:22 < zyp> would be nice if you could just feed it a single 3.3V supply or something
2018-11-15T14:34:40 < karlp> yeah, the nanopi duo2 I'm going to do some protos with you feed it 5V
2018-11-15T14:34:43 < karlp> it gives you 3v3 back again.
2018-11-15T14:35:37 < zyp> ah, that looks cute too

2018-11-15T14:36:13 < zyp> didn't see
2018-11-15T14:36:22 < karlp> wait, neutis needs you to supply core 1.2V as well? lamers

2018-11-15T14:37:34 < zyp> can you put PoE on it as well? :)
2018-11-15T14:37:37 < karlp> that's the version with hlk-pm01 onboard so raw mains in, though not sure theyðll approve mains ac beside the ethernet jack, even if it meets the en61010 clearance
2018-11-15T14:37:51 < karlp> no exposure to poe honestly,

2018-11-15T14:40:15 < karlp> qyx: can you do can with just a can transceiver? or do you still need the bxcan periph or something?
2018-11-15T14:40:31 < karlp> like, coould I just replace the rs485 transciever to a uart with a can transceiver?
2018-11-15T14:40:49 < zyp> no, you need the can periph
2018-11-15T14:41:30 < karlp> yeah, so you're not getting can easily then.
2018-11-15T14:41:41 < karlp> well, not _as_ easily.
2018-11-15T14:43:12 < zyp> a uart with a can transceiver will not have much of a difference from rs485, just different voltage levels
2018-11-15T14:44:23 < qyx> karlp: can tx/rx are on the same pins as usart tx/rx
2018-11-15T14:44:34 < qyx> and can transceiver has almost identical pinout
2018-11-15T14:44:38 < qyx> iirc
2018-11-15T14:45:11 < zyp> yeah, it's possible to design a board that would work with either
2018-11-15T14:45:41 < zyp> for that isolated usb adapter thing I were dicking around with, I planned to make it possible to populate it either for can or for rs485
2018-11-15T14:45:41 < qyx> uhm, not true, at least not on L432
2018-11-15T14:45:51 < qyx> I mean, yes
2018-11-15T14:45:56 < qyx> but not that easy as I though

2018-11-15T15:12:55 < karlp> can you really not do can in software? in linux ?

2018-11-15T15:13:46 < jpa-> i'd say you *could* do it in software on a fast microcontroller, but you wouldn't want to
2018-11-15T15:14:39 < zyp> the can periph reads back every bit it sends, zeroes are dominant so the first node that sees a zero when it tried to send a one backs off
2018-11-15T15:15:08 < karlp> so it's either a can contoller on spi/usb or a mcu with a can peripheral 
2018-11-15T15:15:31 < karlp> like mcp2515 or so?
2018-11-15T15:15:32 < zyp> yeah, linux has kernel support for certain spi-based can controllers
2018-11-15T15:15:35 < zyp> like that one
2018-11-15T15:16:19 < karlp> yeah, that's why I picked it.
2018-11-15T15:16:22 < zyp> once you get it into the kernel, it goes into the network framework, so userland software can open a can socket to send and receive frames
2018-11-15T15:16:36 < karlp> so yeah, I could "easily" replace the rs485 port with a can port "just for you" qyx :)
2018-11-15T15:16:47 < zyp> I haven't tried that myself yet, but I read up on that once because I were planning to

2018-11-15T18:16:32 < Ecco> I have a question regarding a simple situation: an STM32 powered with a single cell LiPo battery
2018-11-15T18:16:52 < Ecco> and a few peripherals too that will draw some power (e.g. a few LEDs)
2018-11-15T18:17:30 < Ecco> my question is about the specific case where the battery is charging *and* the device is powered on
2018-11-15T18:17:53 < Ecco> most charging ICs I've seen measure use a CC-CV approach (which seems to be the good way to charge batteries)
2018-11-15T18:18:09 < Ecco> problem : when the device is on, the MCU and the LED will draw some current
2018-11-15T18:18:24 < Ecco> so in practice the battery's charge is not CC anymore
2018-11-15T18:18:59 < Ecco> problem #2 : the charging IC cannot detect the end of charge
2018-11-15T18:19:19 < Ecco> because the IC says "charge is done when current goes below a certain threshold. e.g. 20mA
2018-11-15T18:19:47 < karlp> don't try and put your device in the charge path?
2018-11-15T18:19:52 < Ecco> but the circuit draws 25mA, so even if the battery only sinks 5mA, the charger will see 30mA being drawn
2018-11-15T18:20:05 < Ecco> karlp: how?
2018-11-15T18:20:44 < Ecco> I guess that's the right approach
2018-11-15T18:20:49 < Ecco> but I don't know how to do this
2018-11-15T18:22:17 < karlp> what charger are you looking atÐ
2018-11-15T18:25:29 < Ecco> This for example: http://legacy.gamebuino.com/wiki/images/6/6f/Gamebuino_r2_schematics.pdf
2018-11-15T18:25:47 < Ecco> so MCP73833-FCI/UN
2018-11-15T18:25:58 < Ecco> They all kinda work the same though
2018-11-15T18:26:11 < Ecco> and actually I'm not sure the charger itself has anything to do with this problem
2018-11-15T18:30:22 < Thorn> there are charger ICs with separate outputs for battery and the load, e.g. http://www.ti.com/product/BQ24072

2018-11-16T00:08:54 < zyp> signed up for some private tracker the other day for some other stuff I want, but like every other private tracker they have silly ratio rules so you can't really download what you want before you've uploaded anything unless you wanna start out wrecking your account privileges
2018-11-16T00:09:43 < zyp> so I'm downloading some random «free to download» shit that looked popular just so I can seed it

2018-11-16T00:28:33 < zyp> which?
2018-11-16T00:28:40 < Steffanx> They just force you to do a ratio of 1:1 or seed 72 hours
2018-11-16T00:28:43 < Steffanx> Pretome
2018-11-16T00:28:54 < zyp> well, force you how?

2018-11-16T11:32:02 < kakimir> 2017 - 2018 models
2018-11-16T11:34:07 < kakimir> how can you resist something like attiny416
2018-11-16T11:37:25 < kakimir> it's not a discussion
2018-11-16T11:37:37 < kakimir> just a statement
2018-11-16T11:38:50 < kakimir> statement: 8bit is not done yet
2018-11-16T11:39:01 < PaulFertser> kakimir: please compare with stm8
2018-11-16T11:41:00 < jadew> there's plenty of love for the AVR in here
2018-11-16T11:41:08 < jadew> I like them
2018-11-16T11:41:09 < PaulFertser> Haohmaru: have you seen direct gcc avr codegen comparison with sdcc stm8 codegen? Assuming one doesn't need C++.
2018-11-16T11:41:52 < kakimir> PaulFertser: I get 8bit minibeast for 60cents or 50cents @100pcs
2018-11-16T11:42:27 < PaulFertser> Haohmaru: ok, avr got support for modern C++, stm8 doesn't. What else?
2018-11-16T11:42:37 < jadew> also, there are at least 5 people here who are secretly using arduino
2018-11-16T11:42:52 < kakimir> I think stm8 starts with 80cents in small quantities
2018-11-16T11:43:10 < kakimir> sure it's different thing when you buy 10k pcs
2018-11-16T11:43:28 < jadew> PaulFertser, long standing community
2018-11-16T11:43:48 < jadew> AVRs always had better support than PICs
2018-11-16T11:44:19 < jadew> there's lots of example code out there, lots of problems already solved
2018-11-16T11:44:32 < PeterM> nah, theres no need to secretly use tarduino when you can just mbed...
2018-11-16T11:45:12 < kakimir> jadew: new AVRs are another world
2018-11-16T11:45:38 < jadew> PaulFertser, also, without having read STM8 datasheets, the Atmel datasheets are awesome
2018-11-16T11:45:52 < kakimir> way you handle registers etc. peripherals architecture and everything has changed
2018-11-16T11:46:09 < jadew> interesting, haven't looked into them
2018-11-16T11:46:42 < PaulFertser> jadew: community matters for tricky stuff like software usb emulation, agreed. But most of the code available for avr seems to be crappy.
2018-11-16T11:46:55 < kakimir> or was it that these new tinys have some xmega type architecture in them
2018-11-16T11:47:00 < jadew> PaulFertser, that's enough to get into it
2018-11-16T11:47:09 < kakimir> never touched anything but tinys so I don't know
2018-11-16T11:47:21 < PeterM> according to friends that use the new attinys they are a lot nicer than the old ones
2018-11-16T11:47:47 < jadew> the old ones had some limited peripherals, maybe that's what's improved?
2018-11-16T11:47:53 < PaulFertser> jadew: stm8 can be OCD'd with cheap stlink. And I'm not sure if GDB supports debugging of newer (or any) avr parts at all. That would be an important point for me.
2018-11-16T11:47:59 < kakimir> https://en.wikipedia.org/wiki/ATtiny_microcontroller_comparison_chart
2018-11-16T11:48:05 < jadew> for example the USI... that was " " this far from bit-banging
2018-11-16T11:48:24 < jadew> PaulFertser, it does
2018-11-16T11:48:42 < kakimir> new ones all have UART, TWI master/slave, SPI master/slave
2018-11-16T11:48:43 < jadew> but not all parts have support for debuggig
2018-11-16T11:48:44 < PeterM> with much nicer mappings of regisers and more logical mnemonics, more powerful peripherals etc
2018-11-16T11:49:47 < jadew> I'm really sorry microchip bought them...

2018-11-16T11:55:29 < Steffanx> Tiny1617 is cooler :P
2018-11-16T11:55:33 < Steffanx> Or 817.
2018-11-16T11:55:37 < Steffanx> Because new.
2018-11-16T11:55:52 < jadew> kakimir, eh, can do some other stuff too, but yeah
2018-11-16T11:55:52 < kakimir> new avrs are cheaper than old ones
2018-11-16T11:55:55 < Steffanx> They shouldve used a new name, its totally different
2018-11-16T11:56:15 < jadew> yeah, it does look like they use the xmega architecture
2018-11-16T11:56:20 < Sadale> This one sounds familiar.
2018-11-16T11:56:27 < Sadale> jadew, isn't it the new attiny series?
2018-11-16T11:56:38 < jadew> 2313?
2018-11-16T11:56:44 < jadew> it's old
2018-11-16T11:56:57 < Steffanx> Now the 1617
2018-11-16T11:57:06 < Steffanx> No*
2018-11-16T11:57:12 < Steffanx> Is pretty new
2018-11-16T11:57:27 < jadew> that one seems to be a bit more expensive
2018-11-16T11:58:09 < Sadale> I see. 2313 is an old one
2018-11-16T11:58:33 < Sadale> Originally I planned to use tinyAVR-1 mcu for my game console project.
2018-11-16T11:58:45 < Sadale> I ended up using STM32 because I failed to source tinyAVR-1 in small amount >_<
2018-11-16T11:59:17 < jadew> probably that's where the "tiny" comes from
2018-11-16T11:59:49 < jadew> what are some of the cheapest MCUs?
2018-11-16T12:00:03 < jadew> *that will still be available 10 years from now
2018-11-16T12:07:05 < kakimir> no
2018-11-16T12:07:22 < kakimir> you mean address space?
2018-11-16T12:07:33  * karlp looks at the topic and and wonders why anyone's even bothering discussing xmegas vs pics
2018-11-16T12:09:47 < jadew> karlp, exchanging info
2018-11-16T12:11:32 < jadew> actually this talk was constructive
2018-11-16T12:11:45 < jadew> just came to my attention I can't do what I want with the attiny2313
2018-11-16T12:11:46 < Steffanx> Im happy you joined the discussionkarlp
2018-11-16T12:12:17 < karlp> you're welcome
2018-11-16T12:12:33 < Steffanx> :)
2018-11-16T12:13:38 < zyp> hrm, I think my body is one day off
2018-11-16T12:13:48 < Sadale> I wonder why AVR mcus are so expensive.
2018-11-16T12:14:01 < Sadale> STM32F030F4P6 only costs $0.38 at 10k.
2018-11-16T12:14:05 < Sadale> At that price you could only get a ATtiny13A.
2018-11-16T12:14:12 < zyp> last night felt like a friday night, and this morning my body refused to get out of bed to go to work
2018-11-16T12:14:15 < Sadale> And STM32F030F4P6 is far more powerful
2018-11-16T12:14:24 < zyp> got up at like 10:30
2018-11-16T12:15:08 < karlp> heh, doesn't matter whether mine "refuses" or not, it has to get up.
2018-11-16T12:15:20 < karlp> kids gotta get to school!
2018-11-16T12:15:31 < Sadale> hmm.
2018-11-16T12:15:44 < Sadale> I meant, I'm pretty sure that AVR is still used these days.
2018-11-16T12:15:49 < Sadale> Why'd anyone buy them?
2018-11-16T12:16:11 < Sadale> I don't think the hobbyist market is enough to support Atmel (and now Microchip)
2018-11-16T12:16:30 < jadew> they're used in plenty commercial products
2018-11-16T12:16:37 < jadew> good ICs
2018-11-16T12:17:09 < Sadale> So what're the reasons to use AVR over cheaper, more powerful microcontrollers of other brands?
2018-11-16T12:17:15 < karlp> familiarity
2018-11-16T12:17:23 < jadew> also, peripherals
2018-11-16T12:17:28 < zyp> karlp, yeah, my problem is that I don't have any pressing reasons to get up
2018-11-16T12:17:38 < karlp> jadew: I disagree with that
2018-11-16T12:17:38 < jadew> atmel didn't just have good datasheets and tools
2018-11-16T12:17:49 < karlp> we switched from an avr to an stm32 purely _because_ of peripherals
2018-11-16T12:17:52 < Steffanx> Zyp is on holiday?
2018-11-16T12:18:02 < karlp> atmel is like, "one uart is enough! harhar"
2018-11-16T12:18:17 < Steffanx> My samd20 has more
2018-11-16T12:18:19 < jadew> ah, I don't mean the number of peripherals, but their implementation
2018-11-16T12:18:28 < zyp> I don't have any appointments or chores that needs to be done in the morning, and my working hours are completely flexible
2018-11-16T12:18:32 < karlp> when the implementation is "computer says no" .... :)
2018-11-16T12:18:41 < jadew> Atmel had (probably still do) really good peripherals
2018-11-16T12:18:41 < zyp> Steffanx, no, I'm at work now
2018-11-16T12:18:42 < karlp> samd didn't exist then :)
2018-11-16T12:19:02 < zyp> just a couple hours later than when I usually show up :p
2018-11-16T12:19:29 < karlp> jadew: so, what avr periph is "better" in such a way that you'd notice?
2018-11-16T12:19:49 < karlp> it's sure not those USI "uart/spi/i2c" botchjobs
2018-11-16T12:19:58 < karlp> kakimir referred to them earlier, and I had to work with themtoo,
2018-11-16T12:20:09 < jadew> I don't remember the exact details, because I had a list of complaints several years ago, but for example the UART on atmeg8 which is a shit chip, is better than anything found on STM32
2018-11-16T12:20:11 < karlp> the adcs are slow, but you get selectable internal reference?
2018-11-16T12:20:25 < karlp> ok, so go look at your ocmplaints again honestly,
2018-11-16T12:20:27 < jadew> has a more complete implementation (can interface with more stuff)
2018-11-16T12:20:37 < karlp> like, now that you know what you're doing, is there anything actually missing from the stm32 one really?
2018-11-16T12:20:50 < karlp> what does "more complete implementation" mean for a uart in your mind?
2018-11-16T12:21:01 < karlp> does it mean "16550 register compatible" ?
2018-11-16T12:21:04 < karlp> or ... ?
2018-11-16T12:21:12 < jadew> for example, you can't synchronize multiple UART receivers
2018-11-16T12:21:27 < jadew> if you could, then you could use them at a higher speed/CPU freq
2018-11-16T12:21:47 < karlp> what does that mean? synchrononize multiple uarts?
2018-11-16T12:22:07 < karlp> is that just a way of doing qspi via multiple uarts?
2018-11-16T12:22:09 < jadew> have them work on a given clock, like SPI sort of
2018-11-16T12:22:15 < karlp> or dma from a port?
2018-11-16T12:22:18 < jadew> instead of having the peripheral oversample the data
2018-11-16T12:22:32 < karlp> so all the uSart options that the stm32 has too?
2018-11-16T12:22:32 < zyp> of course you can
2018-11-16T12:22:42 < zyp> what karlp said
2018-11-16T12:22:42 < karlp> are you _sure_ you just didn't know how to do them with the stm32 periphs?
2018-11-16T12:22:47 < jadew> you can't, it can't be a slave IIRC
2018-11-16T12:22:50 < karlp> rather than "the periphs suck, avr is better"
2018-11-16T12:22:56 < zyp> uh
2018-11-16T12:23:01 < zyp> of course usart can be a slave
2018-11-16T12:23:35 < jadew> grr... I didn't want to get into this because I knew I'd have to go check my notes
2018-11-16T12:23:45 < jadew> there's something it doesn't do right about it, for sure
2018-11-16T12:23:53 < karlp> yes, you shouldn't make unsubstantiated claims.
2018-11-16T12:23:56 < jadew> and it took a lot of hackery to get it done
2018-11-16T12:24:06 < karlp> that got beaten into me in high school
2018-11-16T12:24:50 < jadew> karlp, told you it's been years since I had these complaints, but they were real, let me check what exactly I had to do
2018-11-16T12:25:09 < karlp> please :)
2018-11-16T12:27:19 < zyp> strike the last thing I said, looks like jadew is right
2018-11-16T12:27:35 < jadew> karlp, ^
2018-11-16T12:27:46 < karlp> what does "slave mode" mean?
2018-11-16T12:27:48 < zyp> the USART CK pin is apparently output only, the receiver doesn't give a fuck about the clock anyway
2018-11-16T12:27:55 < karlp> oh, for sync ?
2018-11-16T12:28:01 < zyp> yes
2018-11-16T12:28:13 < karlp> can't sync slve be done with spi?
2018-11-16T12:28:19 < zyp> yes
2018-11-16T12:28:29 < karlp> so... same again,
2018-11-16T12:28:40 < jadew> not really, because SPI is synchronized at byte level
2018-11-16T12:28:45 < jadew> or word-level
2018-11-16T12:28:46 < jadew> whatever
2018-11-16T12:29:01 < jadew> while USART can have bits coming in at any point
2018-11-16T12:29:04 < karlp> ok, hooray, you found a missing feature.
2018-11-16T12:29:10 < jadew> it wasn't just that
2018-11-16T12:29:24 < karlp> is it a selling point of avrs that their "More complete usarts let you do sync slave" though?
2018-11-16T12:29:38 < karlp> I still disagree with your claim that avr's selling point is their peripheral strength
2018-11-16T12:29:41 < jadew> don't know, but my impression was that Atmel had better peripherals and that is a selling point
2018-11-16T12:29:49 < jadew> I'm probably not the only one who noticed this
2018-11-16T12:30:13 < karlp> I think you probably _are_ the only one who noticed that.
2018-11-16T12:30:56 < jadew> heh, could be...
2018-11-16T12:32:26 < karlp> new sam4e stuff looks compettiive though
2018-11-16T12:32:33 < karlp> old sam3 was jsut too expensive
2018-11-16T12:33:07 < Steffanx> Isnt xmega older than sam stuff, at least the cortex-m sams
2018-11-16T12:33:55 < jadew> Steffanx, it is
2018-11-16T13:49:55 < jadew> ok... I think I'm gonna start using lcsc
2018-11-16T13:52:21 < zyp> enjoy
2018-11-16T13:52:34 < jadew> why is that worrying me? :)
2018-11-16T13:52:46 < jadew> should I expect surprises?
2018-11-16T13:53:17 < zyp> dunno, got no experience with lcsc
2018-11-16T14:02:05 < jadew> hmm... thought it's a good deal, but it looks like I can get the same part for the same price from TME

2018-11-16T14:50:22 < friendofafriend> You're just dropping 125kHz coils on those pin headers?  
2018-11-16T14:50:36 < catphish> correct
2018-11-16T14:51:15 < friendofafriend> That's neat!  Is it for some kind of access control system?
2018-11-16T14:51:27 < catphish> all the matching circuitry is on the board, just a coil on each pin header, as far as i can tell they can be connected at a reasonable distance without any issues

2018-11-16T14:51:43 < catphish> my friend wanted a way to detect the position of trains on a model railway
2018-11-16T14:52:21 < catphish> he thought putting coils under the track would be the easiest way
2018-11-16T14:53:53 < friendofafriend> That's a good idea!  Do you think the wire runs to the coils will be a problem?
2018-11-16T14:54:36 < catphish> here's the schematic https://nutty.tk/multirfid.pdf
2018-11-16T14:55:20 < catphish> i tested a run through a 5m length of chunky cable and it worked exactly the same
2018-11-16T14:56:07 < BrainDamage> are the trains still brushed dc? the one I had as a kid was pretty noisy electrically
2018-11-16T14:56:07 < friendofafriend> Are you gutting a transponder from a card/fob or something else?
2018-11-16T14:56:09 < BrainDamage> it even had sparks
2018-11-16T14:56:28 < BrainDamage> the train engines might interfere with the nfc
2018-11-16T14:57:31 < catphish> so i think it'll be fine, i'll probably connect it up with cat5, that should largely eliminate the effect of the cable run

2018-11-16T16:38:45 < con3> Is there anyway to send a variable length message over spi? using dma I need to define a data length, although it would be great if I could change this to be one transfer of variable length?
2018-11-16T16:40:07 < con3> Just sending between two mcu's. one little esp and the stm is receiving the data
2018-11-16T16:43:15 < con3> hmm.. what's happening rn is that I need to define a fixed length of data, but then sometimes I'm sending a little less. So when I send this data it doesn't trigger the dma callback, the next time I send a portion of data it overwrites the previous portion of data, because I've got it in circular mode and then things get weird
2018-11-16T16:44:05 < con3> so just always send the amount of data that will trigger the callback, but pad the sent data with some bits?
2018-11-16T16:44:52 < con3> ¯\_(ツ)_/¯
2018-11-16T16:46:40 < con3> thanks Haohmaru, I'll need to think about how the receiver will handle this for a bit. But I understand what you mean. 
2018-11-16T16:50:27 < con3> I think that might be one of the easier solutions. Didn't think variable data lengths would turn out this weird. I'll prepend the data with a length and add zero byte padding until I can find a better solution
2018-11-16T16:50:33 < con3> thank you for all the help
2018-11-16T16:50:41 < con3> Really appreciate it

2018-11-16T19:53:15 < bitmask> (I switched to altium Steffanx )
2018-11-16T19:53:25 < englishman> you have some silkscreen outside of the board outline there
2018-11-16T19:53:58 < bitmask> I'm homebrewing them, wont be having any silkscreen
2018-11-16T19:54:21 < bitmask> which is why the vias are a bit strange, since I can't plate them
2018-11-16T19:54:37 < englishman> old skool
2018-11-16T19:54:38 < bitmask> and everything being big
2018-11-16T19:54:53 < englishman> milled or etched

2018-11-16T19:55:08 < englishman> good luck
2018-11-16T19:55:18 < bitmask> I may end up just going to jlcpcb in the end but I have the supplies to at least try first
2018-11-16T19:56:38 < bitmask> I only have 10 2-pin JST-XH connectors unfortunately, I may have to change some to right angle (I have 10 of each)
2018-11-16T19:56:53 < bitmask> stupid problem

2018-11-16T20:01:34 < Steffanx> better start using mentor graphics
2018-11-16T20:01:41 < bitmask> wut is that

2018-11-16T22:00:19 < Adluc> or whatever hack to avoid IDC THT
2018-11-16T22:04:17 < Adluc> yea, single row smd will probably make it, keeping pinout as is on st-links/bmp
2018-11-16T22:04:29 < Adluc> just with swdio/gnd/swclk
2018-11-16T22:05:03 < Thorn> and Vtarget
2018-11-16T22:05:09 < Thorn> for pro debuggers

2018-11-17T00:03:43 < englishman> sac305 paste, sn99 wire
2018-11-17T00:03:53 < ds2> those are all higher temp 
2018-11-17T00:03:57 < englishman> of course
2018-11-17T00:04:08 < ds2> higher temp = more likely to delaminate PCBs

2018-11-17T00:04:50 < ds2> I am referring to multiple rework cycles (i.e. prototypes)
2018-11-17T00:04:57 < englishman> use less heat then
2018-11-17T00:05:04 < englishman> and get better skills
2018-11-17T00:05:06 < ds2> solder won't melt
2018-11-17T00:05:18 < englishman> refer to point #2

2018-11-17T01:13:17 < catphish> i believe i am ok, but there is a lot of blood pooled in there, there's still quite a considerable lump a week on, might ask a doctor if it doesn't go away soon
2018-11-17T01:14:00 < catphish> it doesn't seem to be causing any harm to the rest of the arm, so i don't think it's serious, also surprisingly unpainful, but it looks dramatic

2018-11-17T01:53:09 < kakimir> get delta and then offset it right with that delta?
2018-11-17T01:57:09 < BrainDamage> run the filter twice, in forward and reverse
2018-11-17T01:57:23 < BrainDamage> you'll get twice the order, but 0 phase difference
2018-11-17T01:57:35 < BrainDamage> ( this works only for linear filters )
2018-11-17T01:57:52 < kakimir> BrainDamage: wait how..
2018-11-17T01:58:50 < BrainDamage> even realtime has buffering
2018-11-17T01:59:01 < kakimir> currently 2 values
2018-11-17T01:59:08 < kakimir> last and current
2018-11-17T01:59:41 < kakimir> I look at exponential averaging
2018-11-17T01:59:45 < BrainDamage> if your buffering has size 2 then you just shift the "now" back 2 indeed
2018-11-17T01:59:53 < BrainDamage> exponential averaging is just a FIR filter
2018-11-17T02:01:34 < con3> I know what all the words are that you guys are saying seperately, but when you put them together like that I'm completely lost
2018-11-17T02:02:00 < BrainDamage> that's correct, you cannot process in realtime without latency, it's actually a mathematical theorem for the filter to be causal
2018-11-17T02:08:34 < kakimir> hey
2018-11-17T02:08:52 < kakimir> could I form 3 streams of averaging

2018-11-17T14:50:48 < kakimir> "pointer targets in passing argument 1 of 'usart_putstring' differ in signedness [-Wpointer-sign]"
2018-11-17T14:54:09 < kakimir> char is default unsigned
2018-11-17T14:54:18 < kakimir> what kind of logic is to have then signed string
2018-11-17T14:54:25 < kakimir> me cast it cracki
2018-11-17T14:54:39 < kakimir> just cast everything
2018-11-17T14:56:06 < kakimir> usart_putstring((uint8_t*)" \n\r", 10);
2018-11-17T14:56:13 < kakimir> is this correcto?
2018-11-17T14:56:31 < kakimir> nice
2018-11-17T14:56:52 < kakimir> size_t
2018-11-17T14:57:35 < kakimir> well that line just does linefeed in putty
2018-11-17T14:57:38 < kakimir> iirc.
2018-11-17T14:58:10 < kakimir> string has termination normally and it will use it
2018-11-17T14:58:19 < kakimir> to break
2018-11-17T14:58:28 < kakimir> that is just for stuff
2018-11-17T14:59:44 < kakimir> unimportant
2018-11-17T14:59:49 < kakimir> this is diagnosis print
2018-11-17T15:00:53 < antto> in gcc there is -funsigned-char or some such
2018-11-17T15:03:59 < kakimir> flag is in use
2018-11-17T15:04:06 < kakimir> it was by default
2018-11-17T15:04:08 < kakimir> and
2018-11-17T15:04:08 < mawk> no Cracki 
2018-11-17T15:04:25 < mawk> well char is different, but for the rest no a using/typedef is the same as the pointed type
2018-11-17T15:04:49 < mawk> char != unsigned char and char != signed char
2018-11-17T15:05:25 < mawk> you said something about typedefs and C++
2018-11-17T15:05:35 < mawk> the char/unsigned char/signed char thing is more fundamental than a typedef, and C does it too
2018-11-17T15:06:00 < mawk> it's equal under the hood, but if you put unsigned char in char you need a cast
2018-11-17T15:06:02 < mawk> or you'll get a warning
2018-11-17T15:06:23 < mawk> even if it matches
2018-11-17T15:08:04 < mawk> hold on
2018-11-17T15:09:09 < mawk> https://godbolt.org/z/uPjomU
2018-11-17T15:10:17 < mawk> the implicit cast works without a warning if you don't use pointer types for instance
2018-11-17T15:10:31 < mawk> you need pointers if you want to see the error
2018-11-17T15:11:17 < mawk> also cppreference talks about it probably
2018-11-17T15:11:28 < mawk> "char - type for character representation which can be most efficiently processed on the target system (has the same representation and alignment as either signed char or unsigned char, but is always a distinct type). "
2018-11-17T15:16:17 < mawk> also I showed you the C++ compiler in my link but it's the same with the C compiler
2018-11-17T15:16:21 < mawk> just it's a warning and not a hard error

2018-11-18T00:37:35 < kuldeep> Hello, im connecting Quectel M66 to STM32, Is there any AT command library that i can use to perform communication?
2018-11-18T00:38:17 < englishman> if a device takes an AT command set, typically the mfg would provide the library if any
2018-11-18T00:38:37 < kuldeep> englishman, for stm32? (library for uC too?)
2018-11-18T00:38:51 < englishman> typically a platform agnostic lib.

2018-11-18T00:40:21 < englishman> hmm idk the last module i used with an AT command set
2018-11-18T00:40:56 < englishman> if theres no lib you can spin one up yourself
2018-11-18T00:42:28 < kuldeep> yea i can roll my own code, but sending command without making sure they are executed properly (or a command is taking long) so, instead of just blindly sending command over uart, i have to carefully sense that something is taking time or error occur
2018-11-18T00:43:32 < englishman> one of the typical problems with at command set modules
2018-11-18T00:44:04 < kuldeep> some command can take more than 10 seconds [worst case], i cannot just blindly place send command and accept data in 2ms (which is the usual time), in worst that can be 10 seconds.

2018-11-18T17:53:01 < bitmask> I'm looking at a schematic and it says to use either a LDO regulator or dc-dc regulator.  what is the latter?
2018-11-18T17:53:19 < Thorn> buck converter probably
2018-11-18T17:53:19 < bitmask> says dc-dc is more efficient, is it a switching regulator?

2018-11-18T23:51:31 < kakimir> I have
2018-11-18T23:51:39 < kakimir> I actually looked at it few years back
2018-11-18T23:53:23 < kakimir> only thing cheaper than XMC1100 is PIC16F (5V, 12bit ADC, smd, 8-32k of flash)
2018-11-18T23:53:56 < aandrew> so CMX1100is cheap CM0
2018-11-18T23:54:04 < kakimir> XMC price in thousands is like 0.5
2018-11-18T23:55:13 < kakimir> I can reason XMC1100 over PIC16F with ease of porting from another CM0

2018-11-19T01:19:07 < englishman> i put 6kw heater in a pot
2018-11-19T01:19:10 < englishman> to make beer
2018-11-19T01:19:21 < kakimir> eventually box gets very hot and after that it can reach ignition point for materials

2018-11-19T01:20:23 < kakimir> apparently I must go attolic
2018-11-19T01:23:36 < Steffanx> but only the old version
2018-11-19T01:23:43 < Steffanx> now its STM32 only :P
2018-11-19T01:24:25 < kakimir> 8.0.0 downloaded
2018-11-19T01:25:12 < Steffanx> its not keil.
2018-11-19T01:34:56 < kakimir> what are practical limitations of truestudio?
2018-11-19T01:36:49 < kakimir> this has try buy explore buttons in IDE toolbar
2018-11-19T01:37:03 < Steffanx> yes, back in the time it was a commercial ide
2018-11-19T01:40:46 < kakimir> do I need to pay?
2018-11-19T01:45:52 < kakimir> but if I want to use 8.0.0
2018-11-19T01:46:04 < kakimir> not truestudio stm32
2018-11-19T01:46:49 < kakimir> hah
2018-11-19T01:46:54 < kakimir> clicked buy
2018-11-19T01:47:15 < kakimir> "No product matching your selection"
2018-11-19T01:47:42 < kakimir> so they do not sell new licences anymore
2018-11-19T01:47:48 < kakimir> for old TS
2018-11-19T01:49:18 < kakimir> let's download and install DAVE4
2018-11-19T01:53:50 < kakimir> manuf takes care of it's customers
2018-11-19T01:58:22 < Steffanx> ah lol this is bad. Spend quite some time to get the RTC wakeup stuff to work.
2018-11-19T01:58:33 < Steffanx> but the f042 does not support that -_-

2018-11-19T01:59:29 < englishman> which
2018-11-19T01:59:35 < englishman> im pretty sure f042 has rtc wakeup
2018-11-19T01:59:43 < englishman> so you must be talking about something weird and or specific
2018-11-19T02:00:21 < Steffanx> Talking about: "Automatic wakeup unit generating a periodic flag that triggers an automatic wakeup interrupt.".
2018-11-19T02:00:51 < Steffanx> and its pretty clear it does not support it, but for some reason i didnt really check :P
2018-11-19T02:02:54 < kakimir> plan more - groundwork less
2018-11-19T02:02:57 < englishman> for comparison which chip does have it?

2018-11-19T02:03:41 < englishman> so it has to be reset each time
2018-11-19T02:03:57 < Steffanx> You have to use the alarm i guess
2018-11-19T02:04:29 < englishman> yea
2018-11-19T02:04:29 < englishman> gay
2018-11-19T02:04:34 < Steffanx> Very much.
2018-11-19T02:04:35 < englishman> well, just use 072!
2018-11-19T02:04:59 < Steffanx> nah 042 is already there and i dont really care about the time, so will hack it together using the alarm
2018-11-19T02:06:00 < englishman> or L0x2
2018-11-19T02:06:04 < englishman> oh ok
2018-11-19T02:06:21 < Steffanx> > Restarting the RTC all the time
2018-11-19T02:06:25 < englishman> so its an "ensure steffy has work to do" project
2018-11-19T02:06:28 < Steffanx> the time that is
2018-11-19T02:07:25 < Steffanx> Configuring this takes just as much time as the periodic wake up timer, so.. not more or less work to do.

2018-11-19T16:09:26 < jpa-> i've sometimes used a BJT as a diode when i only needed a crappy diode and didn't want to add another component to the BOM
2018-11-19T16:16:28 < karlp> yeah, I've see a bjt used as a diode to as a "regulator" even on a super cheap ethernet switch design, (the manufacturer even mentioned this explicitly)
2018-11-19T16:16:39 < karlp> but this is an actual packaged darlington connected like that.
2018-11-19T16:17:35 < jpa-> that's just a diode with some extra pins ;)
2018-11-19T16:18:07 < Thorn> you can remove it and increase R as necessary

2018-11-19T16:18:28 < Ecco> Hi :)
2018-11-19T16:18:41 < Ecco> I'm trying to hook up some Flash to an STM32 over a QuadSPI link
2018-11-19T16:18:43 < Thorn> was it designed by a javascript brogrammer
2018-11-19T16:18:47 < karlp> the "led" is an optocoupler, I ðresume they didn't feel they could driver it directorly from the mcu pins.
2018-11-19T16:19:00 < Ecco> I'm reading the doc and I'm wondering how the memory-mapped mode can work
2018-11-19T16:19:02 < Thorn> but they do
2018-11-19T16:19:12 < Ecco> namely, how can the STM32 know what commands to send to the flash chip?
2018-11-19T16:19:15 < Thorn> the switch switches the whole current
2018-11-19T16:19:28 < Thorn> there is no amplification coming from that darlington
2018-11-19T16:19:33 < karlp> the "switch" in that falstead thing is the mcu pins
2018-11-19T16:19:46 < Thorn> yeah I figured
2018-11-19T16:19:48 < karlp> yeah, seems pretty bogus to me.
2018-11-19T16:19:55 < Thorn> of course
2018-11-19T16:21:58 < karlp> the part is a nrnd diodes inc part too, fmmt12, but the pcb is labeled 2017, so ... good stuff.

2018-11-19T18:01:08 < Ecco> I'm wondering about the memory-mapped mode
2018-11-19T18:01:28 < Ecco> I understand there's a "manual" mode, where you manually craft commands for the chip
2018-11-19T18:01:32 < Ecco> this one I understand
2018-11-19T18:01:55 < Ecco> But I wonder how the STM32 knows what commands to send to the flash chip when it acts in memory-mapped mode
2018-11-19T18:18:55 < jpa-> Ecco: in memory mapped mode it only needs one instruction ("READ"); you put that into the register beforehand
2018-11-19T18:19:03 < Ecco> oh
2018-11-19T18:19:11 < Ecco> ok crystal clear
2018-11-19T18:19:42 < Ecco> I thought there was some kind of magic with the "serial flash discovery" command involved at some point
2018-11-19T18:19:54 < Ecco> Cracki: in practice it's not, in the chip I considered
2018-11-19T18:20:10 < Ecco> (and I haven't seen it mentionned anywhere in the ST docs)
2018-11-19T18:20:21 < jpa-> e.g. RM0385 page 391 section QUADSPI usage -> memory mapped mode explains it
2018-11-19T18:20:36 < Ecco> thanks jpa- !
2018-11-19T18:21:10 < Ecco> ok wait
2018-11-19T18:21:12 < Ecco> I've read this before
2018-11-19T18:21:34 < Ecco> where does it say what you just did? :D
2018-11-19T18:21:46 < Ecco> (aka "you put a command in a register so the QuadSPI controller know what to replay)
2018-11-19T18:21:54 < jpa-> "The programmed instruction and frame is sent when an AHB master is accessing the
2018-11-19T18:21:55 < jpa-> memory mapped space.
2018-11-19T18:22:06 < Ecco> oh, ok, my bad guys
2018-11-19T18:22:13 < Ecco> I'm going back to reading I guess
2018-11-19T18:22:18 < Ecco> thanks
2018-11-19T18:22:28 < jpa-> no no, you have to post a shitty meme link first

2018-11-19T21:24:16 < kakimir> I wonder what happens if I connect my target to samsung phone charger and debugger + usb-uart to my laptop that is powered from wallbrick too
2018-11-19T21:24:53 < jpa-> if you connect ground first, it'll work
2018-11-19T21:25:11 < jpa-> otherwise you might get 120VAC at some microamps between the systems
2018-11-19T21:25:50 < kakimir> shitti laptops and phone chargers do not have grounding
2018-11-19T21:26:05 < jpa-> i mean ground of your systems, usb cables etc.
2018-11-19T21:26:36 < kakimir> you mean I connect target and laptop first and then close the loop by connecting wall bricks?
2018-11-19T21:26:54 < kakimir> my soldering iron had 70VAC at works
2018-11-19T21:26:59 < kakimir> ts100
2018-11-19T21:27:05 < kakimir> until I grounded it to GND rail
2018-11-19T21:27:18 < kakimir> also something like 170mikroamps
2018-11-19T21:27:20 < kakimir> to GND
2018-11-19T21:27:55 < kakimir> anyway
2018-11-19T21:27:59 < kakimir> yolo
2018-11-19T21:32:00 < jpa-> it doesn't matter what you connect first, as long as you connect ground pin first on any connections you make
2018-11-19T21:37:56 < kakimir> yes
2018-11-19T21:38:17 < kakimir> usb connectors are like that

2018-11-19T22:24:05 < Steffanx> Would you put such adapter there?
2018-11-19T22:24:50 < PaulFertser> I mean different "wallchargers" from the 50Hz transformers era.
2018-11-19T22:24:59 < zyp> for angled plugs, it's better to have the cables come out on one side each than to have one go down and one go up
2018-11-19T22:25:03 < Steffanx> Yes i understand
2018-11-19T22:25:39 < qyx> ah makes sense
2018-11-19T22:25:53 < qyx> we have schuko D outlets
2018-11-19T22:26:01 < qyx> so it is not possible to plug them upside down

2018-11-20T00:45:39 < Steffanx> Or do you also sell
2018-11-20T00:46:44 < englishman> i will try the pid controller boiler tonight
2018-11-20T00:49:55 < kakimir> i noticed I cannot drink beer
2018-11-20T00:50:43 < kakimir> my stomach doesn't like it
2018-11-20T00:50:53 < kakimir> nowdays I only drink wine
2018-11-20T00:53:50 < kakimir> with beer day after I feel stomach pain and emptiness
2018-11-20T00:53:56 < kakimir> with wine I feel only emptiness
2018-11-20T00:58:18 < Steffanx> You mean after 3 bottles of wine?
2018-11-20T00:59:26 < kakimir> usually just one
2018-11-20T00:59:43 < Steffanx> And snus
2018-11-20T00:59:50 < kakimir> I get hangover from just one beer
2018-11-20T00:59:54 < kakimir> thinkabout that
2018-11-20T01:00:25 < Steffanx> Id visit a doctor 
2018-11-20T01:01:16 < kakimir> interesting
2018-11-20T01:01:38 < kakimir> beer -> hangover -> medical problem potentially
2018-11-20T01:01:55 < kakimir> my shit works otherwise just fine
2018-11-20T01:03:02 < Steffanx> No, but a hang over from a single beer...
2018-11-20T01:03:55 < kakimir> it's a bliss
2018-11-20T01:04:00 < kakimir> all I need to know
2018-11-20T01:05:48 < friendofafriend> I'm with Steffanx, you should have your liver checked.
2018-11-20T01:06:04 < Steffanx> Hah
2018-11-20T01:07:07 < kakimir> I don't get such hangover with wine or vodka
2018-11-20T01:07:45 < kakimir> i'd say it's inflaming my system that beer
2018-11-20T01:07:55 < kakimir> and it cannot recover properly
2018-11-20T01:09:40 < friendofafriend> Might check your blood sugar, also.  We'd miss you in ##stm32.

2018-11-20T01:29:00 < catphish> totally on-topic question: is there a way to combine a timer with DMA to load a series of on/off times into an array and have the timer switch a pin with those timings in a loop without involving the cpu core?
2018-11-20T01:29:53 < catphish> [ie 1ms on, 10ms off, 2ms on, 5ms off]...repeat without interrupting the cpu, just loading the next period from memory with dma each time
2018-11-20T01:38:19 < bitmask> catphish yes, I did that to control ws2812b strips
2018-11-20T01:39:07 < catphish> bitmask: i've heard of people using it for LED strips, which is why i thought it might be possible, but couldn't see from the docs how
2018-11-20T01:39:54 < bitmask> well you need to at least fill the buffer each time (unless it repeats) but you use dma to set the CCR capture/compare register
2018-11-20T01:40:22 < catphish> Cracki: your method could work, my requirements are not that tight really, i'm looking into doing dcc (50/100uS on and 50/100uS off), but i'm keen to do it with minimal CPU interruption
2018-11-20T01:43:58 < kakimir> could counter runaway be caused by some 8bit 16bit stuff
2018-11-20T01:44:15 < kakimir> condition check goes wrong etc.
2018-11-20T01:45:00 < catphish> thanks, reading now
2018-11-20T01:51:49 < catphish> looks like section 5.3 explains how to do it
2018-11-20T01:53:34 < catphish> looks like it loads new values from dma each time the timer overflows, i guess it can go this fast enough for it to immediately apply to the (already started) cycle
2018-11-20T01:56:38 < catphish> perfect :)
2018-11-20T02:03:26 < kakimir> okays

2018-11-20T10:11:08 < Ecco> Out of curiosity, why are most (all?) serial Flash chips using NOR bits?

2018-11-20T10:26:26 < zyp> NAND flash is harder to work with, you only get indirect access, so they are usually read/written in full blocks

2018-11-20T10:28:13 < zyp> but they also have a controller in between that does wear levelling and shit

2018-11-20T13:36:31 < marble_visions> mamed: no experience with mapple mini, but there should not be an issue with the prolific usb to serial. you have to be cautious with higher (2mbps) speeds as i've seen this to cause problems sometimes
2018-11-20T13:37:02 < marble_visions> exactly what problem are you experiencing?
2018-11-20T14:34:02 < karlp> I'd imagine that mamed was just using the tools provided, so had need/desire to get into things like that.

2018-11-20T14:39:23 < mamed> Cracki: it has boot jumper pins. so to programme it just change the jumpers. i was concerned about the usb to serials different from ftdi one.
2018-11-20T14:40:08 < mamed> my pc does not see my ftdi one(which is ft232rl) so i thought prolific one should do this fine.

2018-11-20T14:53:24 < mamed> marble_visions: when i plug my ftdi programmer my device manager did not recognize it( i mean i dont even see it in unknown devices or somewhere)
2018-11-20T15:01:14 < mamed> no
2018-11-20T15:01:20 < mamed> that is the problem
2018-11-20T15:01:37 < mamed> maybe my ftdi programmer chip has a problem.
2018-11-20T15:26:05 < mamed> there is no usb programmer on it afaik

2018-11-20T16:28:43 < mawk> some company wrote all their code in C because they didn't want the "heavy C++", and now they've developed an object layer for C and it became so unreadable that they want to make a parser that displays nice graphics of all the object stuff

2018-11-20T16:51:59 < mawk> ah
2018-11-20T16:52:02 < PaulFertser> aandrew: remember gnome was created before C++ was anywhere near mature, so there was a point back then.
2018-11-20T16:52:18 < aandrew> PaulFertser: fair point
2018-11-20T16:53:02 < mamed> PaulFertser: gnome was ok until they switched to bizzare design.(gnome3x i think)
2018-11-20T16:53:56 < PaulFertser> mamed: I have no idea, been using lightweight WMs through all the years (on XMonad currently).
2018-11-20T16:54:29 < jpa-> gnome apps atleast have gotten worse
2018-11-20T16:54:59 < jpa-> fortunately mate-desktop has forks of many of the old good ones
2018-11-20T16:57:44 < PaulFertser> abiword seems sane though
2018-11-20T16:58:15 < aandrew> I liked kde until 4.x where they broke *everything* and then spent the next decade fixing shit
2018-11-20T16:58:25 < aandrew> I just use xfce now
2018-11-20T16:58:28 < PaulFertser> That said, I guess it's not part of gnome, so unrelated. But it's using Gtk+
2018-11-20T16:58:29 < jpa-> yeah, that's when i switched back to icewm
2018-11-20T16:59:11 < aandrew> actually my usual linux gui environment now is just xfce over xrdp and accessing it with jump desktop on my hackintosh :-)
2018-11-20T16:59:30 < aandrew> xrdp took a bit to get working but I'm really happy with it now. rdp is way better than vnc
2018-11-20T16:59:58 < mamed> xfce is ok . but i would like to use a qt based lightweight one.
2018-11-20T17:00:05 < mamed> with macos menubar of course.
2018-11-20T17:01:29 < mawk> did you try x2go aandrew ?
2018-11-20T17:01:38 < mawk> apparently it's a (proprietary) alternative to both which is supposedly faster
2018-11-20T17:01:49 < mawk> but rdp is already quite nice indeed
2018-11-20T17:02:11 < aandrew> PaulFertser: wow what a shitty schematic

2018-11-20T17:02:45 < PaulFertser> aandrew: looks shitty or conceptually shitty?
2018-11-20T17:02:57 < aandrew> PaulFertser: it's just a really ugly schematic. hard to follow
2018-11-20T17:03:06 < sync> yeah aandrew, I used kde3 for quite some time but then everything™ went to shit and I moved on
2018-11-20T17:03:40 < mamed> ubuntu's unity was cool before they moved to gnome3(shell)
2018-11-20T17:03:40 < aandrew> mawk: I've looked at x2go, nx, opennx, a few others too I think (been a while, I was on a crusade when nx went to shit)
2018-11-20T17:03:56 < aandrew> so now it's just xrdp and ssh tunnelling, which is plenty fast for what I do
2018-11-20T17:04:19 < BrainDamage> rdp is quite adequate

2018-11-20T18:18:01 < mawk> yeah
2018-11-20T18:18:05 < mawk> but I prefer static inline to macros
2018-11-20T18:18:13 < mawk> it amounts to the same and is prettier
2018-11-20T18:18:19 < mawk> or namespace { inline } in C++
2018-11-20T18:18:49 < marble_visions> mawk: do you inline the whole if-else, or just the condition?
2018-11-20T18:18:55 < mawk> the condition
2018-11-20T18:19:06 < karlp> encapsulate an entire function that returns bool, and just let the compiler sort it out if it's complicated

2018-11-20T18:19:40 < karlp> I don't get worked up on inline or not, just let the compiler handle it.
2018-11-20T18:19:56 < mawk> static inline also means you can put the condition in a .h and include it as many times as you want
2018-11-20T18:19:59 < karlp> you can then have nice doxygen/javadoc on the function too, so ctrl-space over the if will show you what'

2018-11-20T21:51:23 < BrainDamage> but you can split the bills, and it's not too hard to fit another person even in the smallest of the apartments, only the bed matters really
2018-11-20T21:55:17 < Thorn> attn BrainDamage do you know anything about this https://phys.org/news/2018-11-infinite-dimensional-symmetry-possibility-physicsand-particles.html
2018-11-20T21:56:43 < BrainDamage> not in any meaningful way
2018-11-20T21:57:41 < Thorn> I googled E10 supergravity and there are articles from > 10 years ago
2018-11-20T21:58:31 < zyp> even when handwashing dishes, if you get chunks in the water you're doing something wrong
2018-11-20T21:58:52 < zyp> you're supposed to rinse shit before you fill up the sink, then you wash it
2018-11-20T22:00:34 < zyp> also, even when water is free, heating it generally isn't
2018-11-20T22:05:21 < aandrew> man $1k in digikey parts 
2018-11-20T22:05:26 < aandrew> not including some of the most expensive parts
2018-11-20T22:05:46 < aandrew> mind you I'm ordering some shit in bulk too just because it's silly to order 10 resistors when you can get 5000 for $15

2018-11-20T22:59:10 < englishman> aandrew: did you find somewhere to assemble your shit
2018-11-20T22:59:47 < englishman> lol kakimir level SMAing
2018-11-20T23:03:47 < Steffanx> i dont recall, bitmask
2018-11-20T23:04:03 < bitmask> we have a lidl now
2018-11-20T23:04:26 < Steffanx> You have to blame Cracki for that, not me.
2018-11-20T23:04:33 < bitmask> why
2018-11-20T23:04:37 < Steffanx> He's german, im not.
2018-11-20T23:04:43 < bitmask> oh its german?
2018-11-20T23:04:45 < Steffanx> Yeah
2018-11-20T23:04:55 < bitmask> oops, I thought it was swedish

2018-11-20T23:06:03 < bitmask> Oh I was thinking of netherlands

2018-11-20T23:06:23 < englishman> lol so this option firm in florida bet on natural gas going down, instead it went up 20%. they lost all of their clients money and put some clients in a debt position
2018-11-20T23:06:44 < karlp> how can you get clients in debt like that? I don't understand that level of mismanagement.
2018-11-20T23:06:59 < karlp> we had a "money market fund" here that managed to lose 70% of value in 2008.
2018-11-20T23:07:00 < englishman> it really is mismanagement
2018-11-20T23:07:21 < Steffanx> Greedy people got screwed. :P
2018-11-20T23:07:23 < karlp> a fucking money market fund, you should be worst case being 0%, not negative.
2018-11-20T23:07:47 < englishman> not with options
2018-11-20T23:08:11 < karlp> so what, client had an option, they loaned to the firm?
2018-11-20T23:08:15 < englishman> buying naked options can force you to buy high and sell low.
2018-11-20T23:08:24 < englishman> err selling
2018-11-20T23:08:33 < englishman> well it was an option trading firm
2018-11-20T23:08:39 < englishman> so the firm sold options with client money
2018-11-20T23:09:41 < englishman> karlp, after the battery crunch a lot of chinastores just stopped shipping 18650s at all. maybe you can get someone on alibaba to sell you some via sea freight

2018-11-20T23:47:34 < englishman> good luck
2018-11-20T23:47:47 < englishman> why didnt you give it to dong for $5k
2018-11-20T23:48:19 < englishman> or just buy the entire thing from macrofab
2018-11-20T23:48:31 < aandrew> englishman: that may have been a better solution in hindsight
2018-11-20T23:48:38 < aandrew> I was 100% convinced that carsan could do it in the time I wanted

2018-11-20T23:49:00 < englishman> shit macrofab even has impedance control
2018-11-20T23:49:09 < englishman> you can probably get your custom stackup too if you pay the bux
2018-11-20T23:50:09 < englishman> can you plug all your shit in and get a quote from them
2018-11-20T23:50:14 < englishman> you're only out a few k so far right
2018-11-20T23:50:18 < englishman> and can proto the power stuff
2018-11-20T23:51:16 < aandrew> yes. 10 panels were USD$4k. parts are going to be expensive
2018-11-20T23:52:15 < aandrew> I just ordered a plain quick turn steel stencil (for hte bgas), that was $125+90 shipping
2018-11-20T23:52:33 < aandrew> stentronics would do it for CAD$140 and $cheap shipping but not sure of turn around time
2018-11-20T23:52:56 < englishman> their stencils are huuuuuge
2018-11-20T23:53:01 < englishman> I didn't use them again
2018-11-20T23:53:07 < englishman> tho they are fast and very good
2018-11-20T23:53:12 < aandrew> yes they are
2018-11-20T23:53:18 < aandrew> (HUGE and fast and good qual)
2018-11-20T23:53:33 < aandrew> this is all for hand assembly though

2018-11-21T00:01:58 < englishman> no :(
2018-11-21T00:02:11 < karlp> when did amazon drop so much?
2018-11-21T00:02:30 < englishman> last 2 weeks
2018-11-21T00:02:36 < englishman> along with the rest of the market
2018-11-21T00:04:35 < karlp> who makes a product with 2.54mm pitch 2x12 headers, but then puts the _other_ headers, not anywhere near 2.54mm pitch integrals

2018-11-21T00:05:34 < karlp> no, they at least got the vertical spacing oik, just that single stagger, and it's off by 1.27mm iirc on arduino
2018-11-21T00:05:50 < karlp> so, sane, done for explainable reasons, even if completly moronic in hindsight
2018-11-21T00:06:09 < karlp> this just feels like "we dragged the headers around on 1mil grid until things fit ok"
2018-11-21T00:06:13 < aandrew> heh I actaully have a friendly arm board coming in, it's the same SoC as in my hantek mso5074fg
2018-11-21T00:06:24 < englishman> it might force connector orientation. or something
2018-11-21T00:06:26 < aandrew> want to dick around a bit with developing alternative fw for that without risking my scope
2018-11-21T00:06:31 < karlp> heh,
2018-11-21T00:07:06 < karlp> yeah, I've got a duo2 module on the way for one proto, (that's evenly spaced) but this is the "core" module, which might be better.

2018-11-21T01:22:30 < karlp> can you get "sideways" rj jacks? https://imgur.com/a/8vNtI6W
2018-11-21T01:23:23 < zyp> please clarify
2018-11-21T01:23:36 < zyp> oh, wait, I get it
2018-11-21T01:24:03 < zyp> haven't seen any, but weirder stuff exists
2018-11-21T01:24:12 < karlp> yeah, it's just a "no" really I think.
2018-11-21T01:24:25 < karlp> I know it would all fit in that case, but not with modules and 3rd party pieces probably :)
2018-11-21T01:24:30 < karlp> nyway, bed
2018-11-21T01:24:47 < zyp> does it really matter though? anybody can rotate a RJ45 plug 90 degrees to make it plug in
2018-11-21T01:31:15 < zyp> google didn't turn up any, so if that connector orientation is a problem you'd probably have to go with a different pcb orientation
2018-11-21T01:32:45 < zyp> if you don't want a flat pcb in the bottom, of the enclosure, maybe you could use a vertical one across, with a top entry rj45 jack, if it'll reach
2018-11-21T01:33:15 < zyp> but a separate small connector pcb would probably be better
2018-11-21T01:33:33 < zyp> or do rigidflex :)
2018-11-21T01:45:41 < aandrew> not sure I understand
2018-11-21T01:45:52 < aandrew> how is a "sideways" jack different from taking a standard jack and rotating it 90 degrees?
2018-11-21T01:53:16 -!- emeb [~ericb@ip68-2-69-216.ph.ph.cox.net] has left ##stm32 []
2018-11-21T02:05:36 < zyp> picture the rj45 connector as a cube, the cube has six faces, one of them is where the rj45 plug enters, one of the other five will be soldered to the board
2018-11-21T02:06:18 < zyp> if the front has the socket, normal right angle connectors have the board on either the top or the bottom face, depending on whether it's a tab-up or tab-down variant
2018-11-21T02:06:28 < zyp> and then you have vertical sockets, they have the board on the back faces
2018-11-21T02:06:51 < zyp> but karlp wanted one that mounts to the board on one of the left or right faces
2018-11-21T02:07:11 < zyp> or if you put the board flat, you can describe it as a tab-left or tab-right connector
2018-11-21T02:08:17 < zyp> if you look at the picture karlp posted, that's a board that goes vertically in a din rail enclosure, so with the pictured jack, the tab will be on the left side when the enclosure is in the normal orientation
2018-11-21T02:08:44 < zyp> and I guess karlp want it with the tab up, so it's easier to extract for the user
2018-11-21T02:09:29 < zyp> or maybe even to fit, since jacks are wider than they are tall
2018-11-21T02:10:54 < zyp> if you want an analogy, compare https://media.digikey.com/Photos/Wurth%20Electronics%20Photos/A-USB-A-E-R.jpg and https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcSa45KnBmc23J9Kp0J09v6BqpWhmo1F74HoP4NSzK9w7kK6aR6q
2018-11-21T02:11:04 < zyp> they are both right angle connectors :)
2018-11-21T02:15:51 < kakimir> is it normal for chip internal temperaturemeter to read +30 in +21 ambient?
2018-11-21T02:16:13 < kakimir> AVR micro running with default clocks and factory calibration
2018-11-21T02:16:27 < zyp> look at the thermal specs and figure it out for yourself
2018-11-21T02:17:15 < zyp> if Vdd * Idd * RthJA is 9 degrees, it's normal.
2018-11-21T02:20:38 < kakimir> got to love things like manufacturer storing factory calibration values in chip
2018-11-21T02:21:17 < zyp> what avr is this?
2018-11-21T02:21:49 < kakimir> 816
2018-11-21T02:22:16 < zyp> attiny816?
2018-11-21T02:23:06 < zyp> soic or qfn?
2018-11-21T02:24:46 < kakimir> soic in this case
2018-11-21T02:25:04 < kakimir> I don't get even a one full kelvin of temperature rise
2018-11-21T02:26:15 < zyp> RthJA for that package is 44 according to the datasheet, so a nine degree difference from ambient suggests that it's dissipating around 200mW, that sounds too high
2018-11-21T02:27:03 < kakimir> calibration is just off of there is no calibration
2018-11-21T02:27:27 < zyp> RthJC is 21, so the top of the chip should measure 25 degrees or so in those conditions
2018-11-21T02:27:54 < zyp> so yeah, sounds more like your calibration is fucked up
2018-11-21T02:29:19 < kakimir> ok
2018-11-21T02:29:26 < zyp> the qfn apparently have almost twice the thermal resistance as the soic, wonder why
2018-11-21T02:29:26 < kakimir> well
2018-11-21T02:29:40 < kakimir> zyp: to ambient or what?
2018-11-21T02:29:42 < zyp> it has an exposed pad so you'd think it would have less resistance
2018-11-21T02:29:47 < zyp> yeah
2018-11-21T02:30:06 < kakimir> thing is.. that soic is huge
2018-11-21T02:30:19 < kakimir> like biggest chip I have used for a while
2018-11-21T02:30:24 < zyp> it depends on pcb layout, of course, so maybe the number is without it being connected to a plane
2018-11-21T02:31:17 < zyp> normally qfns have a lot less resistance to ambient because they are soldered directly to a big plane that acts like a heatsink
2018-11-21T02:32:44 < kakimir> if temperature sensor is like +-8Celsius off
2018-11-21T02:33:09 < kakimir> it's pretty good when it comes with no additional price
2018-11-21T02:34:27 < kakimir> if you need some accurate measurements you don't use internal sensor anyway
2018-11-21T02:37:27 < kakimir> I'm using it to not allow lipo charger to charge in gross undertemperature
2018-11-21T02:37:38 < kakimir> also limit if it's just cold
2018-11-21T02:37:48 < kakimir> also overtemperature for the charger

2018-11-21T03:11:44 < aandrew> oof. $1k digikey order out
2018-11-21T03:11:49 < aandrew> hopefully it shows up tomorrow
2018-11-21T03:12:26 < aandrew> of course I hit order and it's like "oh, three of the 80 items are backordered, what do you want to do?"
2018-11-21T03:12:58 < aandrew> 2.2uF 16V 0603 X5R capacitors are out, I had to split up the order into a qty10 and qty7 when I really wanted qty100
2018-11-21T03:13:05 < aandrew> but 17 will cover my immediate needs
2018-11-21T03:13:44 < kakimir> 1k order in late 2018 = 100pcs mlccs

2018-11-21T08:46:04 < dongs> on STM?
2018-11-21T08:46:09 < emeb_mac> yeah
2018-11-21T08:46:14 < dongs> 47.
2018-11-21T08:46:16 < dongs> workedg reat.
2018-11-21T08:46:24 < emeb_mac> I started with 0.1uf but that was overkill
2018-11-21T08:46:30 < emeb_mac> 100nf was better.
2018-11-21T08:46:38 < dongs> . isnt that same
2018-11-21T08:46:47 < dongs> you mean 10nf?
2018-11-21T08:46:47 < emeb_mac> err yeah 10nf
2018-11-21T08:47:14 < emeb_mac> with 0.1 it was getting maxcount errors
2018-11-21T08:47:22 < emeb_mac> which are a PITA to deal with
2018-11-21T08:47:30 < dongs> are you using hal tarsh?
2018-11-21T08:47:35 < emeb_mac> yeah
2018-11-21T08:47:37 < dongs> my maxcount stuff handles it super easy.
2018-11-21T08:48:14 < emeb_mac> aha - did you end up doing custom / non-HAL stuffs?
2018-11-21T08:48:26 < dongs> yeah
2018-11-21T08:48:33 < dongs> ported hal-stuff to stdperiph-like interface
2018-11-21T08:48:51 < emeb_mac> neat.
2018-11-21T08:49:14 < emeb_mac> I'm just using modified HAL example code now. Works OK w/ 10nf cap
2018-11-21T08:49:38 < emeb_mac> super-dumb thresholding though. may need to rethink that.
2018-11-21T08:50:03 < dongs> did you use differetn scan groups or whatever
2018-11-21T08:50:13 < dongs> my last bigger proj with touch had like 11 b uttons

2018-11-21T08:50:29 < emeb_mac> yeah - I've got 8 sensors in 3 groups 
2018-11-21T08:50:31 < dongs> and 4 pins per group
2018-11-21T08:50:34 < dongs> ok cool

2018-11-21T08:51:25 < dongs> on gotMCE i just return and restart sampling again on next pass
2018-11-21T08:51:31 < emeb_mac> OK so you just clear it out
2018-11-21T08:51:36 < dongs> ya
2018-11-21T08:52:06 < emeb_mac> I just set my maxcnt to be way bigger than the cap would ever generate

2018-11-21T11:24:25 < zyp> badly?
2018-11-21T11:34:35 < karlp> zyp: yeah, I was thinking of rigidflex :)  was hoping to avoid either the connector cost for board to boad, or the assembly hassle of soldered edge connectors.  not sure I follow what you mean by using a vertical entry jack, that seems to be the same problem, unless I want the port facing a different way, and then require the users to have right angle cables to fit nicely.
2018-11-21T11:35:01 < karlp> zyp: and yeah, it wasn't really tab up/sideways, it was just to fit at all.
2018-11-21T11:35:22 < karlp> the "width" of the jack is too wide for the space on the case there, but the height would have been ok if it was rotated 90.
2018-11-21T11:37:14 < zyp> by vertical socket, I mean that you flip the board so that it sits sideways in the enclosure, not vertical
2018-11-21T11:37:28 < zyp> a vertical socket mounted on the board would then point downwards
2018-11-21T11:37:40 < zyp> and you get to keep the front stuff
2018-11-21T11:38:37 < zyp> probably won't fit well anyway

2018-11-21T12:54:28 < zyp> karlp, what do you need batteries for? have you checked where ebike people buy their cells?
2018-11-21T12:55:01 < karlp> no idea where that would even be, would have to ask some people
2018-11-21T12:55:16 < karlp> I still don't understand where batteries are turning up at all anymore
2018-11-21T12:55:21 < karlp> _everyone_ refuses to ship them.
2018-11-21T12:55:46 < zyp> idk
2018-11-21T12:56:24 < karlp> somehow we can have moutains of power tools, but not the batteries inside them....
2018-11-21T12:56:38 < qyx> try tme, they ship without hassle

2018-11-21T12:57:12 < zyp> but at least they ship stuff
2018-11-21T12:58:14 < zyp> when I bought my battery three years ago I think it came with DHL, when one of my friends bought one just a month or two ago I think it came with TNT

2018-11-21T15:43:42 < englishman> i wonder if i can upgrade this 2G module to 3G myself
2018-11-21T15:44:06 < englishman> the procedure does not require antenna replacement, just the telematics module
2018-11-21T15:50:30 < karlp> PaulFertser: heh, good, but fairly uninteresting question :)
2018-11-21T15:51:00 < karlp> the "GEM" (an electronics module under the glovebox with fuses on it, has a broken pin on the connector for the headlgiths.
2018-11-21T15:51:29 < karlp> I got a spare from the wreckers, but naively missed that the one I bought didn't have central locking, the fuse was missing, but there was also simply nothing behind the fuse
2018-11-21T15:52:05 < karlp> I'm still waiting on a couple of things to be fixed for the inspection, and if it all gets trhough (should do) then I'll go back to the wreckers and try and find one that has _both_ :)
2018-11-21T15:54:32 < zyp> hrm
2018-11-21T15:54:50 < PaulFertser> karlp: and replacing the connector is not possible as it's all covered in epoxy or somesuch?
2018-11-21T15:54:51 < zyp> tried adding a second ACM interface to an usb device, of course that doesn't simply just work on windows
2018-11-21T15:55:07 < zyp> so now I need to figure out IAD I guess
2018-11-21T15:55:16 < karlp> PaulFertser: the broken pin is on the mainboard, it's... not viable to replace it,
2018-11-21T15:55:22 < karlp> one tick, I'll find a pic.
2018-11-21T15:55:49 < karlp> certainly not when the price of the replacement module was .... the price of 1.5 18650 batteries locally.

2018-11-21T16:48:56 < davor> How come this F3 is declared as having an FPU and a Cortex-M4 core instead of an M4F core? https://www.st.com/en/microcontrollers/stm32f318k8.html
2018-11-21T16:49:20 < zyp> because it's the same thing?
2018-11-21T16:49:27 < zyp> M4F is M4 plus a FPU
2018-11-21T16:51:32 < davor> Ah, I see. It's just that I seem to remember some mcus being specifically stated as having an M4F and others an M4 core so I kind of expected the F there
2018-11-21T16:51:38 < davor> If it has an FPU
2018-11-21T16:52:03 < davor> Parametric search on Farnell accidentally made me exclude a lot of mcus with FPUs that way
2018-11-21T16:52:56 < zyp> strictly speaking there's no "M4F", it's just a convention that means M4 with FPU
2018-11-21T16:53:20 < zyp> and yes, as far as I'm aware, every stm32 with M4 has FPU

2018-11-21T16:56:36 < karlp> but all the st m4's have fpu
2018-11-21T16:56:54 < davor> Ah I see, thanks! Also, I'm moving from an ATtiny44 with 4 KB of flash and 256 B of RAM, it's doing some dirty base-2 log and exp calculations which works. I suppose reimplementing the code with proper equations and division should work on the MCU linked, with 64 KB of flash, 16 KB of RAM and an FPU?
2018-11-21T16:57:13 < karlp> sure
2018-11-21T16:57:28 < davor> Someone somewhere told me the thing is fairly small, but hell, it's not that small :p
2018-11-21T16:57:39 < davor> Compared to a t44 at least
2018-11-21T16:58:19 < karlp> depends on the tiny44 package, but yes, there's not as many options taht small pacakge wise.
2018-11-21T16:58:40 < karlp> even the f0s that are similar in package size will probably just happily run normal maths faster than your hacks ont he t44
2018-11-21T16:59:54 < karlp> fuck off with your single precisions constant.
2018-11-21T17:00:02 < karlp> that's _not_ required for using the fpu
2018-11-21T17:00:12 < karlp> that's required for making your code non-portable and avoiding learning what c means.
2018-11-21T17:00:36 < karlp> never gonna let you spread bad practises like that :)
2018-11-21T17:00:56 < davor> Sounds good. I basically just need the capability to run the maths, 3 PWM channels, 6 ADC channels and 1 UART, and my budget is 1 GBP per MCU for 50 qty, and no BGA

2018-11-21T17:03:35 < englishman> compared to the stm32 clones with 3MiB they are small i guess
2018-11-21T17:04:00 < davor> karlp: that STM in particular, 64 KB flash, 16 KB RAM. coming from a t44, it's massive
2018-11-21T17:04:21 < karlp> davor: I was referring to whoever told you that "STM is ont he small side"

2018-11-21T18:55:47 < emeb> this
2018-11-21T18:56:00 < emeb> piles of ziploc bags isn't cutting it for me
2018-11-21T18:56:12 < aandrew> I have a bunch of photographic film negative sleeves that i have to actually start using for the cut tape stuff, but I'm buying more reels now so need a real reel book case or something
2018-11-21T18:56:24 < jadew> emeb, I'm in the same situation
2018-11-21T18:56:54 < aandrew> I have a bunch of identical little cardboard boxes that most of the cut tape is organize into.. one for MCUs, one for inductors, one for power management ICs, one for opamps, one for diodes, etc.
2018-11-21T18:56:55 < jadew> I put the ziplock bags in ikea boxes, but then what do you do if you have multiple projects sharing components?
2018-11-21T18:57:10 < jadew> (I currently store them by project)
2018-11-21T18:57:10 < aandrew> then I have two bigger boxes for all my Rs and Cs respectively
2018-11-21T18:57:26 < aandrew> and I have a couple boxes that store ALL the components for a particualr project separate from my "stock"
2018-11-21T18:57:33 < emeb> yep
2018-11-21T18:57:39 < aandrew> I want tmove all cut tape to film negative sleeves in a binder
2018-11-21T18:57:47 < aandrew> and then something for reels
2018-11-21T18:57:59 < emeb> and then I need a part and can't find it in general stock because it's off in a project bag I forgot about
2018-11-21T18:58:26 < jadew> I bet someone has solved this
2018-11-21T18:58:36 < aandrew> emeb: yeah that happens to me too
2018-11-21T18:58:38 < aandrew> which I want to end
2018-11-21T18:58:42 < jadew> same here
2018-11-21T18:58:55 < aandrew> and I need a better way of remembering that I do have in fact a reel of 10k 0805
2018-11-21T18:59:00 < aandrew> so I stop buying another 100
2018-11-21T18:59:31 < emeb> lol yes - I have so many bags of 100x 10k 0603 because I keep buying them.
2018-11-21T18:59:50 < aandrew> it'd also be really fucking nice to have that in a spreadsheet so when I designing something new I'm looking at parts I already ahve and have designed with. I do most of that by memory but there are some neat chips that I've forgotten I've got 
2018-11-21T19:00:15 < emeb> I tend to use my DK/Mouser order history to figure out if I have a part :P

2018-11-21T19:03:15 < jadew> *pockets
2018-11-21T19:03:19 < jadew> because you can fit more stuff in there
2018-11-21T19:03:36 < aandrew> jadew: the exact ones I have are ...
2018-11-21T19:04:00 < jadew> apparently the guy with the catalog in those pictures used these: https://www.amazon.com/gp/product/B005JCL05I
2018-11-21T19:04:27 < aandrew> http://a.co/d/2wqQmWW
2018-11-21T19:04:45 < jadew> yeah... that's too wide
2018-11-21T19:05:21 < aandrew> not for cut tape
2018-11-21T19:05:35 < aandrew> it's perfect for cut tape in fact

2018-11-21T19:06:51 < davor> Man, QFPs are a lot more expensive on Farnell than QFNs
2018-11-21T19:07:24 < davor> Double for the models I'm looking at
2018-11-21T19:08:10 < jadew> aandrew, those negative films are 35mm wide
2018-11-21T19:08:19 < aandrew> yes
2018-11-21T19:08:25 < jadew> (maybe more, I'm not sure the 35mm takes into account the margins)
2018-11-21T19:08:36 < jadew> isn't cut tape like... 5-6mm wide?
2018-11-21T19:08:37 < aandrew> I'm not putting a single "strip" in each. I'm putting several
2018-11-21T19:08:49 < jadew> yeah, but they'll be loose
2018-11-21T19:08:59 < aandrew> e.g. if I take a strip of 100 0805s, I would cut it to length and put what, 5-6 strips in each pocket
2018-11-21T19:09:00 < jadew> you need something like this: https://www.ebay.co.uk/itm/SMD-SMT-Organizer-Empty-Sample-Book-Pages-For-Resistor-Capacitor-Inductance/172563481445
2018-11-21T19:09:44 < jadew> (which is what my catalog came in)
2018-11-21T19:09:48 < jadew> they fit perfectly
2018-11-21T19:09:53 < jadew> and you can put multiple strips in
2018-11-21T19:10:04 < jadew> but I don't think it will fit bigger ones
2018-11-21T19:10:14 < jadew> say... for a regulator or some bigger package
2018-11-21T19:10:30 < jadew> there's also the fact that you have to label them all
2018-11-21T19:11:51 < aandrew> jadew: sure, but I bet those pockets are 20-30mm wide as well
2018-11-21T19:12:02 < aandrew> well that's what has kept me from starting this project actually
2018-11-21T19:12:07 < jadew> no, they're under 10mm wide I think
2018-11-21T19:12:17 < jadew> let me measure them
2018-11-21T19:12:29 < aandrew> I know I have to use E96 for labelling but I have to make sure there's room enough there that I don't have to try to RE label it after, which would be a royal pain in the ass
2018-11-21T19:12:42 < aandrew> it says 14mm high there
2018-11-21T19:13:19 < jadew> mine are 12 mm inside
2018-11-21T19:14:04 < aandrew> ok
2018-11-21T19:14:06 < jadew> it came with 2 strips of 50 pcs each for each value
2018-11-21T19:14:12 < jadew> and you can easily fit one more
2018-11-21T19:14:15 < aandrew> my idea is to have one pocket for each value, not one pocket for each strip
2018-11-21T19:14:17 < jadew> not sure about 4
2018-11-21T19:14:23 < aandrew> anyway that's the idea

2018-11-21T19:15:29 < jadew> I'm only worried about it being too loose
2018-11-21T19:16:12 < davor> qyx: F318 at qty 50 pcs
2018-11-21T19:16:52 < davor> I'd rather get a QFP package but I'll solder a QFN somehow if it's half the price

2018-11-21T19:18:22 < aandrew> jadew: yeah I would have to find a binder that has a longer back and that can "fold over" and velcro closed. it would *suck* grabbing that thing open-end-down and having a big mess of strips, especially because now they're no longer in their digikey packages with the model/value/etc printed on them
2018-11-21T19:18:47 < aandrew> ok topic change -- I've never hand-reflowed a BGA before. how challenging is this really?
2018-11-21T19:19:05 < aandrew> I have two 0.8mm BGAs (178 and 48 ball) and a 256-ball 1.0mm pitch one
2018-11-21T19:19:24 < aandrew> stencil should be here, I'm just going to populate those and reflow in the toaster oven
2018-11-21T19:19:53 < aandrew> before I actaully put parts on the baord I want to do a couple temp measurement runs to make sure I get a reasonable profile so the solder will actually hit reflow temp 
2018-11-21T19:20:07 < aandrew> but I'm more worried about positioning. it's not like I have the shit to reball

2018-11-21T19:52:51 < jadew> make sure you don't overheat the battery I guess
2018-11-21T19:53:02 < jadew> other than that, I like it
2018-11-21T19:53:13 < jadew> but you didn't say how thick it was
2018-11-21T19:53:23 < jadew> that's going to go on your back I assume?
2018-11-21T19:53:32 < bitmask> they are rated for like 20A and each battery would only be drawing like half an amp at most
2018-11-21T19:53:42 < jadew> ah, cool
2018-11-21T19:53:59 < bitmask> oh right, 5mm, a little thicker than I wanted but the magnets are 3mm thick and I wanted a mm on each side to hold it

2018-11-21T19:55:14 < bitmask> and I want to do a special neck warmer that draws more current and gets hot faster because its a good place to heat up with circulation
2018-11-21T19:55:16 < jadew> is this an effort to go as lightly dressed as possible during the winter, to look cool?

2018-11-21T19:56:08 < bitmask> hah no, I just wanted an active heating 'garment' and I thought a hoodie would be best because if I wore a coat on top the heat would be more insulated and closer to my body
2018-11-21T19:56:22 < bitmask> and if it works well enough I guess I wont need a coat but it wasn't to avoid one
2018-11-21T19:56:51 < bitmask> also I'm more comfortable ruining a hoodie than a coat
2018-11-21T19:57:32 < jadew> if it works from 12v, you can also use it inside a car, hooked up to the car battery

2018-11-21T21:05:36 < Steffanx> 🎉
2018-11-21T21:05:49 < englishman> cant wait to get paid for this crap
2018-11-21T21:09:13 < emeb> but when you get paid for crap then you *have* to do it.
2018-11-21T21:09:31 < emeb> as opposed to hobby crap that you can leave in a box for a year an no one cares
2018-11-21T21:10:43 < emeb> Also, something I'm becoming more aware of lately - when you do contracting / consulting crap (as opposed to working as a direct employee) then projects have a tendency to rise from the dead and come at you years later.
2018-11-21T21:11:26 < emeb> So clients from long ago keep pestering me for support on stuff I've forgotten about. 
2018-11-21T21:14:37 < jpa-> isn't that great? just keep on charging
2018-11-21T21:15:36 < jpa-> and unless your code is a mess, support should be easier than coding
2018-11-21T21:15:58 < jadew> just make sure you're not too efficient
2018-11-21T21:16:14 < jpa-> why not?
2018-11-21T21:16:34 < jadew> because if you handle their request in 1 minute they won't think it's worth $50
2018-11-21T21:16:55 < emeb> If only it were just simple coding tasks - one client in particular always has last-minute emergencies WRT ancient hardware that doesn't work with current computers.
2018-11-21T21:17:09 < emeb> So I can't really *do* anything except tell him he's screwed.
2018-11-21T21:17:24 < emeb> And of course he's always short of cash...
2018-11-21T21:17:29 < jpa-> jadew: that's why i charge only $1.20 for that 1 minute.. and then wonder at the end of the month why isn't there more income ;)
2018-11-21T21:18:00 < jpa-> ah, clients with lack of money are useless
2018-11-21T21:18:10 < emeb> right
2018-11-21T21:18:26 < jadew> I don't think they lack money, they just want to inform you that they want to pay you the least possible
2018-11-21T21:19:12 < jadew> you have to make sure you tell them that it could even take THIS LONG to fix it and it could cost you this much
2018-11-21T21:19:23 < emeb> well, I know for sure this guy blew his entire wad about 8 yrs ago. Then his rich business partner died. Then he sold his stake in the corp to his kids for 100k and has been trying to scrape by on that.
2018-11-21T21:19:39 < jadew> and you don't do anything until they agree to that
2018-11-21T21:20:11 < emeb> Yeah - did that. Always gets no direct response.
2018-11-21T21:20:24 < emeb> Just more pleading
2018-11-21T21:20:33 < aandrew> englishman: I don't like JIT bullshit
2018-11-21T21:20:40 < aandrew> when you need the part at 3am and it's not there, it sucks
2018-11-21T21:21:07 < jpa-> i'd demand prepayment from such clients
2018-11-21T21:21:24 < jadew> yeah, sounds like a good idea
2018-11-21T21:21:39 < aandrew> englishman: is that the edison thing
2018-11-21T21:21:41 < jpa-> of course that only leads to excuses why it doesn't work for them
2018-11-21T21:22:03 < aandrew> emeb: re: contractor zombie projects: yep. it's great
2018-11-21T21:22:07 < aandrew> because you get paid to ramp up again :-)
2018-11-21T21:22:24 < aandrew> jadew has it 100% right
2018-11-21T21:23:06 < aandrew> you don't ever get back to a client with an answer right away. you empathize with their urgency and say you'll get on it but you are booked pretty solidly with other clients and give them the opportunity to beg you to prioritize, which of course you do for $$
2018-11-21T21:23:32 < aandrew> and then depending on the exact request, drag the solution out a bit just to help them accept the bill
2018-11-21T21:23:57 < aandrew> emeb> And of course he's always short of cash...
2018-11-21T21:24:39 < aandrew> one thing that took me WAY too fucking long to learn is that if they haven't got the cash for a $5k retainer up front, they will not have the cash for your weekly/biweekly invoices either and you'll very quickly waste time chasing them for payment
2018-11-21T21:24:43 < jpa-> "Indeed you have a big problem there, and because this technology is so old I'm probably the only one who can help you. I'm currently very busy, but as a service to old client I can help you with a rush fee of only $9999/hr."
2018-11-21T21:24:43 < aandrew> fuck. that.

2018-11-21T21:24:59 < aandrew> jpa-: less india-sounding but yes pretty much :-)
2018-11-21T21:25:02 < emeb> heh
2018-11-21T21:25:47 < jadew> jpa-, it's not about ripping people off, but they're paying for expertise
2018-11-21T21:25:52 < aandrew> and another thing I am getting MUCH better at doing is if they start playing games with payment I inform them that until the cheque clears (not when I get it, but when the bank finally clears it), I am not working one minute longer
2018-11-21T21:26:19 < jadew> and 1 minute of expertise can be worth weeks for someone who doesn't know what he's doing
2018-11-21T21:26:20 < aandrew> that usually resolves cashflow issues very fast. And if it happens twice, I stop work until a retainer is paid and it becomes a "pre pay" kind of setup
2018-11-21T21:26:28 < aandrew> that has only happened once though
2018-11-21T21:26:41 < jpa-> checks.. you still use those?
2018-11-21T21:26:46 < aandrew> jpa-: you have no fucking idea
2018-11-21T21:26:50 < aandrew> I hate them
2018-11-21T21:27:14 < aandrew> and I hate how the bank likes to hem and haw about "well I don't know, we can't release the funds on this $15k cheque for at least 15 business days"
2018-11-21T21:27:28 < aandrew> I pulled all my shit out of one bank and went to another over that bullshit
2018-11-21T21:28:14 < jadew> sounds like paypal
2018-11-21T21:28:19 < aandrew> I was a client for 19 years (since I was a kid) and never had a deposit bounce and they refused to waive the hold. I had a meeting with the manager set up a week later where I informed them that my personal accounts as well as my business accounts, LOC etc were all being closed 
2018-11-21T21:28:37 < aandrew> it wasn't very satisfying becuase they didn't give a shit. "sorry sir, just policy" kind of answer
2018-11-21T21:28:40 < aandrew> but fuck them
2018-11-21T21:28:52 < Steffanx> :)
2018-11-21T21:28:59 < jadew> policy or not, you have to hurt them
2018-11-21T21:29:06 < aandrew> new bank is much better. they *did* hold the first few but then they saw that I was depositing large cheques more or less every week and they have a note on my file now that there are no holds
2018-11-21T21:29:21 < Steffanx> Why dont you tell your clients you dont want cheques?
2018-11-21T21:29:40 < aandrew> Steffanx: most will do ETF but the occasional one still likes old fashioned paper bullshit
2018-11-21T21:29:58 < aandrew> it's even funnier because they overnight every single one of them so it costs them even more than the $50 wire

2018-11-21T21:39:10 < emeb> news to me - I pay many bills by "E-Check" which apparently costs less than a credit-card transaction since it's free to me vs using CC which has a surcharge.
2018-11-21T21:49:59 < mads-> I have a blackpill. Is there no way of powering this with a 5V supply? 
2018-11-21T21:50:03 < mads-> Only 3.3? 
2018-11-21T21:51:24 < aandrew> Cracki: they shouldn't. but they do. I think it's one of those things banks like to make a lot of money on since they're pretty much pure profit
2018-11-21T21:51:47 < aandrew> emeb: in canada that sounds roughly eqivalent to debit cards which have much much much lower fees than CC
2018-11-21T21:52:04 < aandrew> heh
2018-11-21T21:55:23 < mads-> Cracki: Yeah. I just have a 5V already. And I need that for my ws2812b. So it would be optimal. 
2018-11-21T21:58:11 < mads-> Cracki: I don't mind either way. It would just be easier to have 5V in for both STM32 and ws2812b. Instead of 3.3 for one and 5 for the other
2018-11-21T21:58:22 < mads-> Will look at the vcc5v. Thanks
2018-11-21T21:59:09 < mads-> How would that work exactly? For both 5V and 3.3V. I'm a little new at this
2018-11-21T22:00:23 < mads-> Roger. Then how do I get 3.3V from that? 
2018-11-21T22:02:11 < mads-> Aaah, I see now. 
2018-11-21T22:02:13 < mads-> Thanks!
2018-11-21T22:03:26 < mads-> Roger that. I have mutilated a couple of USB cables already
2018-11-21T22:09:23 < englishman> yeaaa my FREE thermaldongix kit arrived
2018-11-21T22:10:00 < englishman> emeb: i mean, to send the bill, and get paid. the work is done.

2018-11-21T22:23:04 < aandrew> this one is for the expensive components to build up one board, and that one board to have only one digitizer connected
2018-11-21T22:23:11 < aandrew> the damned digitizers are $92 apiece
2018-11-21T22:23:17 < aandrew> 5 per board
2018-11-21T22:24:46 < malinus> got a new (nxp) dev board, and accidently erased the flash on the on-board (CMSIS-DAP) programmer/debugger, instead of the chip itself. Now the fucker won't even boot, I guess because it gets clock or something else retarded form the programmer
2018-11-21T22:25:25 < aandrew> malinus: that's not uncommon. the nucleo boards do that to
2018-11-21T22:25:31 < aandrew> not sure why they do that
2018-11-21T22:25:37 < aandrew> how did you manage to zap the flash interface though
2018-11-21T22:26:32 < malinus> aandrew: they do? I've only had discovery boards, and on those the stlink-running chip is completly seprerated. You even have a jumper to disconnect it from SDW.
2018-11-21T22:26:41 < malinus> aandrew: I did it by connecting my jtag to the wrong port, lol
2018-11-21T22:27:48 < aandrew> malinus: the nucleos are the same, but MCO is connected
2018-11-21T22:27:54 < aandrew> like I said, it's stupid
2018-11-21T22:27:59 < aandrew> malinus: ahhh
2018-11-21T22:28:01 < aandrew> that makes more sense
2018-11-21T22:28:55 < malinus> aandrew: I'm still suprised the main chip won't run without the programmer. They don't provide schematics like stm32 does (at least for discovery boards). So it's impossible to tell if it's reset, or some common clock pin or what the fuck is going on
2018-11-21T22:29:52 < aandrew> malinus: that sucks

2018-11-21T22:32:40 < malinus> Cracki: some funny business chip. Again shiity nxp docs, and it's a very small bga package saying "M20AGV 3N86B ACGUG". I'm guessing it's a freescale m4.
2018-11-21T22:33:03 < malinus> well I KNOW it's a m4
2018-11-21T22:34:31 < aandrew> malinus: yeah on nucleo PH0 (OSC_IN) is normally conected to the debugger's 8MHz MCO through a solder bridge.  There is also a not-populated space for a clock and a couple other solder bridges to connect it
2018-11-21T22:36:02 < malinus> Cracki: not openly on their website no. That would sove it. I tried contacting them but no response so far. It's not that exensive but still annoying.

2018-11-21T23:18:22 < kuldeep> Hello
2018-11-21T23:18:31 < kuldeep> I have an lcd (yellow connector, red pcb) [first image] https://robu.in/product/1-44-inch-tft-lcd-color-screen-module-spi-interface-128-x-128-without-touch/
2018-11-21T23:19:43 < kuldeep> problem is, it is not accepting RAMWR command. it is able to accept screen initialization commands [i can see random pixels on screen], screen invert command.  using screen invert command - im able to turn inversion on and off in a loop to confirm that it atleast accept commands.
2018-11-21T23:20:11 < englishman> finished project with 24,000 pth
2018-11-21T23:20:12 < englishman> sent invoice
2018-11-21T23:20:15 < kuldeep> Cracki, my code is based on that, actually multiple libraries
2018-11-21T23:20:17 < englishman> time for a club-mate
2018-11-21T23:20:37 < kuldeep> since im not able to perform RAMWR. i cannot write any data to screen.
2018-11-21T23:20:47 < Steffanx> time for a stroopwafel-mate, englishman
2018-11-21T23:21:25 < Steffanx> Language, crt, language.
2018-11-21T23:21:43 < englishman> where do you think it is failing kuldeep
2018-11-21T23:21:59 < englishman> i think i have used that screen before
2018-11-21T23:22:25 < englishman> https://i.imgur.com/3tG6UWe.jpg
2018-11-21T23:22:28 < englishman> hmm no, different
2018-11-21T23:22:30 < kuldeep> englishman, it is not accepting RAMWR command (or maybe column and row command because they are send before RAMWR)
2018-11-21T23:22:35 < englishman> but ST7735 sounds familiar
2018-11-21T23:23:07 < englishman> how do you know it is not accepting the command
2018-11-21T23:23:15 < kuldeep> englishman, i have also used similiar LCD multiple times. familiar with many commands.
2018-11-21T23:23:23 < kakimir> I need a movie
2018-11-21T23:24:02 < kakimir> else I open kicad at 23:33 and prepaire for tommorow by drawing footprints
2018-11-21T23:24:24 < kuldeep> englishman, because it is able to accept initialization command SLPOUT, display on, normal on.   (if i change something to the initialization, the screen is just blank ie no random pixel on screen)
2018-11-21T23:25:26 < kuldeep> englishman, also, in each loop iteration, i write full screen (With RAMWR) command i use one color out of 8 (so, it is should be visible if behavior change)
2018-11-21T23:25:36 < englishman> and then you send ramwr, and then what?
2018-11-21T23:25:42 < englishman> is there a data/command pin?
2018-11-21T23:26:06 < englishman> download SCHEMARIC
2018-11-21T23:26:08 < kakimir> you know

2018-11-22T00:24:17 < jadew> Steffanx, don't be fooled by that
2018-11-22T00:24:31 < jadew> it might be the best movie I've seen in the past several years
2018-11-22T00:24:37 < Steffanx> No.
2018-11-22T00:24:47 < jadew> and I'm not easy to please

2018-11-22T00:28:15 < jadew> I remember I mentioned starting to watch it last week
2018-11-22T00:28:20 < Steffanx> What kind of substance did you use before watching it?
2018-11-22T00:28:27 < jadew> finished it over the weekend and it was surprisingly ok
2018-11-22T00:28:31 < Steffanx> Or do you use leaded solder?

2018-11-22T08:49:09 < qyx> no.
2018-11-22T08:54:03 < bitmask> I have a noob question.  say I have a 12v battery powering a 5V mcu.  attached to the mcu is an IC with 5V logic levels.  can I attach the GND pin of the IC straight to the battery gnd? 
2018-11-22T08:56:15 < bitmask> onboard, the mcu accepts 12+V
2018-11-22T09:08:59 < bitmask> the battery is 12V and the mcu is 5V
2018-11-22T09:18:36 < jpa-> what does "accepts 12+V" mean? something like regulator on board?
2018-11-22T09:18:58 < jpa-> if the board has a regulator, yeah, GND is usually connected directly and regulator is between +12V and +5V
2018-11-22T09:19:44 < bitmask> yes, he asked if there was a regulator, I said onboard
2018-11-22T09:21:44 < bitmask> I'm just confused about the physics of it.  in this case, gnd is gnd is gnd? doesnt matter at what point it gets connected? I just wasnt sure if the mcu is reading a value from an IC if the IC's gnd pin had to be directly connected to the mcu or if I could connect it downstream right by the battery

2018-11-22T09:25:25 < zyp> it does matter
2018-11-22T09:25:44 < bitmask> so connect it to the mcu
2018-11-22T09:26:04 < zyp> if you look simple at it, all points connected to ground should be at the same level
2018-11-22T09:26:37 < zyp> but if you consider real world physics, you'll have voltage drops across all ground conductors that passes significant current too
2018-11-22T09:27:01 < zyp> so a ground in one device might not exactly equal ground in another device
2018-11-22T09:27:15 < zyp> or it might mostly do, but have some overlaid noise
2018-11-22T09:27:32 < bitmask> so whatever is 'using it' should be connected together, keep connections more direct
2018-11-22T09:27:44 < zyp> and when you start making ground loops, stuff starts getting complicated
2018-11-22T09:28:18 < bitmask> ok thanks, I'll keep things separate for now then and read up on it when I have time
2018-11-22T09:28:59 < zyp> but yeah, basic rule is that the ground for a signal should connect to ground as close to the signal in each end
2018-11-22T09:29:23 < bitmask> gotcha
2018-11-22T09:29:24 < zyp> after all, the ground connector carries the return current, and the longer detour it has to take, the more inductance you add

2018-11-22T13:00:24 < kakimir> what?
2018-11-22T13:01:11 < kakimir> we have had this discusion before
2018-11-22T13:01:53 < kakimir> I use stuff like standard size resistors and caps
2018-11-22T13:02:19 < kakimir> we have had this discusion
2018-11-22T13:02:30 < kakimir> atmel chips do not come with recommended footprint
2018-11-22T13:04:24 < kakimir> oh these are nowdays some standard "JEDEC"
2018-11-22T13:04:40 < kakimir> https://drive.google.com/file/d/1FdIQ0bM4YqIy7wPNGPciNrq20lHm0a36/view?usp=sharing
2018-11-22T13:06:15 < kakimir> I made pin pads by maximum width of pin in datasheet
2018-11-22T13:08:00 < karlp> jadew: alternative to kicad? oh no, kicad's fine, there's no alternative, just a weird project management position to be in where you can't use the current software to contribute tot he current software :)
2018-11-22T13:10:09 < Steffann> Haohmaru pros make their own footprints
2018-11-22T13:10:13 < kakimir> time to do smallest pin pitch yet
2018-11-22T13:10:15 < kakimir> 0.4mm
2018-11-22T13:10:32 -!- Steffann is now known as Steffanx
2018-11-22T13:10:51 < zyp> hmm, this is weird, checked signals with LA, I see a frame being sent repeatedly on CANTX and the echo back on CANRX, but the ACK from the remote node doesn't show up
2018-11-22T13:11:18 < zyp> and the remote is known good
2018-11-22T13:11:45 < kakimir> Haohmaru: check your kicad. I need QFN 20pin 1EP 3x3mm and 0.4mm pin pitch
2018-11-22T13:11:58 -!- ekaOlogik [~quassel@x59cc9a3f.dyn.telefonica.de] has quit [Remote host closed the connection]
2018-11-22T13:12:05 < kakimir> sometimes I need same but with 0.45mm pin pitch
2018-11-22T13:12:28 < kakimir> this thing has only weird sizes like 3x4mm wtf
2018-11-22T13:13:10 < kakimir> oh I found it
2018-11-22T13:13:18 < kakimir> UQFN
2018-11-22T13:13:29 < kakimir> it has ugli rounded pads for pins
2018-11-22T13:13:33 < kakimir> I don't trust this
2018-11-22T13:15:03 -!- drzacek [~drzacek@b941c009.business.dg-w.de] has joined ##stm32
2018-11-22T13:15:08 < kakimir> yes
2018-11-22T13:15:38 < kakimir> but seriously probs anything with anywhere close the pin pattern would work
2018-11-22T13:15:45 < kakimir> and right pin pitch
2018-11-22T13:17:39 < kakimir> corner pins have chamfer inside them
2018-11-22T13:17:56 < kakimir> pins are made of 3pins with same number there
2018-11-22T13:18:43 < kakimir> I thought it was hypothetical possibility to have custom pins
2018-11-22T13:19:23 < kakimir> pads yes
2018-11-22T13:27:50 < kakimir> I won't change kicad version on the fly
2018-11-22T13:28:12 < kakimir> but I think I need to check it after this project
2018-11-22T13:31:12 < kakimir> 5.0.0 rc2
2018-11-22T13:31:16 < kakimir> hnn'
2018-11-22T13:31:43 < kakimir> Version: (5.0.0-rc2-dev-242-g2ff74cb3f), release build
2018-11-22T13:35:47 < kakimir> me don know
2018-11-22T13:36:09 < kakimir> idk idc
2018-11-22T13:36:16 < kakimir> it works
2018-11-22T13:36:24 < karlp> I thoughtyou were running nightlies kakimir?
2018-11-22T13:37:52 < kakimir> not at works
2018-11-22T13:45:28 < Sadale> Is there a limit of the max resistance used if I'm feeding the output of a resistor ladder to an ADC port?
2018-11-22T13:46:15 < karlp> there's a section in the datasheet (not the RM) about the electrical parameters of the adc.
2018-11-22T13:46:56 < Sadale> Right.
2018-11-22T13:47:09 < Sadale> I've just noticed that some MCU has that parameter.
2018-11-22T13:47:14 < Sadale> It's just that the one I was looking at didn't have it.
2018-11-22T13:50:38 < karlp> look harder
2018-11-22T13:50:38 < day> Sadale: the input resistance should be specified somewhere i believe
2018-11-22T13:50:47 < Sadale> Try looking into it yourself.
2018-11-22T13:50:54 < Sadale> STM8S001J3 datasheet.
2018-11-22T13:51:00 < Sadale> This one doesn't have it. I've looked around.
2018-11-22T13:51:49 < zyp> "Try looking into it yourself." is a pretty bad way of asking for help
2018-11-22T13:52:01 < Sadale> lol nope.
2018-11-22T13:52:08 < Sadale> I already got an answer from another document.
2018-11-22T13:53:10 < zyp> good for you
2018-11-22T13:53:42 < Sadale> Somehow it's not in the datasheet. It's just weird.
2018-11-22T13:53:54 < Sadale> Perhaps the guys in ST left it out somehow
2018-11-22T14:04:48 < Sadale> apparnetly I can increase the input impedence by reducing the sampling rate.
2018-11-22T14:07:46 < zyp> page 71 seems to describe it pretty well
2018-11-22T14:08:03 < jadew> anyone got these? https://www.aliexpress.com/item/fast-shipping-50pcs-SMD-SMT-component-container-storage-boxes-electronic-case-kit-the-1-Automatically-pops/32367611676.html
2018-11-22T14:08:25 < qyx> yes
2018-11-22T14:08:32 < jadew> any good?
2018-11-22T14:08:54 < qyx> moderately
2018-11-22T14:08:57 < qyx> I have 200 of them
2018-11-22T14:09:15 < qyx> some of them (~5) are broken
2018-11-22T14:11:17 < Sadale> zyp, except that it said nothing about max input impedance:P
2018-11-22T14:11:57 < Sadale> In fact it has said something. But there's no value given at all.
2018-11-22T14:12:02 < qyx> Sadale: there is even an AN document "how to get best accuracy using stm32 adc"
2018-11-22T14:12:19 < Sadale> cool! Thanks qyx :3
2018-11-22T14:12:29 < Sadale> wow. What's with all these three letters nicknames?
2018-11-22T14:12:49 < Sadale> I relate this to those old school games that allows you to enter three letter names on highscore board.
2018-11-22T14:13:35 < qyx> it tells you how to compute different kinds of possible errors
2018-11-22T14:13:44 < qyx> and adjust external parts/driving to mnimize them
2018-11-22T14:19:37 < aandrew> < zyp> "Try looking into it yourself." is a pretty bad way of asking for help
2018-11-22T14:19:41 < aandrew> < Sadale> lol nope.
2018-11-22T14:19:49 < aandrew> Sadale: yes, it actually is a pretty bad way of asking ofr hlep
2018-11-22T14:19:51 < Sadale> lol
2018-11-22T14:19:53 < aandrew> you found the answer independently which is great
2018-11-22T14:19:59 < Sadale> aandrew, don't worry. I wasn't asking for help at all xD
2018-11-22T14:20:14 < Sadale> I was just like "huh? You don't believe that? Try proofing me wrong yourself!"
2018-11-22T14:20:22 < Sadale> I'm sorry that it came out to be a bit rude, tho :3
2018-11-22T14:20:26 < aandrew> but treating people like this is a pretty good way to get yourslef to the bottom of the list in future
2018-11-22T14:20:29 < aandrew> no worries
2018-11-22T14:20:40 < aandrew> we deal with all kinds of people here and are ourselves all kinds of people
2018-11-22T14:20:52 < aandrew> btw
2018-11-22T14:20:57 < aandrew> < Sadale> wow. What's with all these three letters nicknames?
2018-11-22T14:21:01 < aandrew> < Sadale> I relate this to those old school games that allows you to enter three letter names on highscore board.
2018-11-22T14:21:04 < aandrew> lol :-)
2018-11-22T14:21:07 < aandrew> never thought of it that way
2018-11-22T14:21:23 < aandrew> although I figure we'd see a lot more ASS and DIK and FUK and so on if that were the case
2018-11-22T14:21:31 < Sadale> lol
2018-11-22T14:21:47 < aandrew> in fact those nicks are probably all on freenode, just not in this chan
2018-11-22T14:22:20 < karlp> (sadale was't even looking at stm32 adc specs though...)
2018-11-22T14:22:40 < Sadale> Not yet. Will read it.
2018-11-22T14:22:57 < aandrew> btw got my keil shit figured out last night
2018-11-22T14:22:57 < Sadale> Mainly because I'm looking into STM8 instead of STM32. Anyway, I think specs of STM32 would still parly apply.
2018-11-22T14:23:14 < aandrew> you need to make sure the CMSIS-CORE checkbox is ticked 
2018-11-22T14:23:19 < aandrew> what an idiotic way to write software
2018-11-22T14:24:03 < Sadale> karlp, oh. I thought that you were the guy who asked me to read ""how to get best accuracy using stm32 adc"'
2018-11-22T14:24:50 < Sadale> karlp, Here's why. yes. STM32 ADC does state the max input impedance. But I'm going to use STM8. So I read the specs of STM8. And surprise! There's no max input impedance of adc characteristic in the specs.
2018-11-22T14:25:16 < karlp> which is why we'd been telling you to look better, because we know it's in the stm32 sheets :)
2018-11-22T14:25:37 < Sadale> true.
2018-11-22T14:27:37 < aandrew> lol
2018-11-22T14:27:51 < aandrew> "it's in the datasheet" "I'm using stm8" "look harder int he stm32"
2018-11-22T14:28:14 < Sadale> I guess he's asking me to switch to STM32 xD
2018-11-22T14:28:23 < Sadale> That would work out, tho. I'm still in design stage xD
2018-11-22T14:29:08 < qyx> ou, stm8
2018-11-22T14:29:14 < qyx> then I said nothing
2018-11-22T14:30:05 < Sadale> I guess this isn't the right channel to ask stuffs about STM8
2018-11-22T14:30:40 < Sadale> qyx, still your document may be useful for those design technique and stuffs. Thanks. :3
2018-11-22T14:32:00 < aandrew> Sadale: out of curiousity why are you looking at stm8?
2018-11-22T14:32:07 < Sadale> For fun xD
2018-11-22T14:32:16 < Sadale> Well, it's just another hobbyist project.
2018-11-22T14:32:27 < Sadale> I wanna use the weakest microcontroller possible.
2018-11-22T14:32:40 < Sadale> Then I came up with STM8S001J3
2018-11-22T14:32:47 < Sadale> s/up with/across/
2018-11-22T14:33:15 < aandrew> oh I see
2018-11-22T14:34:33 < Sadale> This is all what I got about this STM8 microcontroller: "During the sample time the input capacitance C AIN (3 pF max) can be charged/discharged by the external source. The internal resistance of the analog source must allow the capacitance to reach its final voltage level within t S. After the end of the sample time t S , changes of the analog input voltage have no effect on the conversion result. Values for the sample clock t S depend on 
2018-11-22T14:34:33 < Sadale> programming."
2018-11-22T14:34:41 < Sadale> It also came with a few equations.
2018-11-22T14:35:08 < Sadale> The equations is in a separate document.
2018-11-22T14:35:32 < Sadale> I wonder if what it really meant is, there's no max input impedance as long as the equation is satisfied.
2018-11-22T14:37:24 < zyp> naturally
2018-11-22T14:38:22 < aandrew> that seems odd though; usually they'll spec the internal resistance to the internal cap
2018-11-22T14:38:50 < Sadale> aandrew, agreed. In fact, I've also checked another STM8 microtroller. That's STM8L instead of STM8S.
2018-11-22T14:38:56 < aandrew> 99% of the time IDGAF because I'm driving the input with a voltage follower so a few kohms of input resistance is of no consequence
2018-11-22T14:38:57 < Sadale> And STM8L does have max input impedance.
2018-11-22T14:39:31 < Sadale> What I'm trying to do now is to increase the input resistance to as high as possible.
2018-11-22T14:41:19 < karlp> huh, boost converter with an enable pin.
2018-11-22T14:41:31 < dongs> why not
2018-11-22T14:41:33 < karlp> turning it off..... turns off boost.
2018-11-22T14:41:40 < karlp> but jsut connects input to ouput.
2018-11-22T14:41:41 < dongs> and?
2018-11-22T14:41:43 < dongs> cool
2018-11-22T14:41:55 < karlp> not what I would have expected from an enable pin.
2018-11-22T14:42:02 < karlp> I guess that could be useful sometimes?
2018-11-22T14:42:03 < dongs> well considering how boost works
2018-11-22T14:42:09 < dongs> when its "off"
2018-11-22T14:42:14 < dongs> the vcc just flows to out
2018-11-22T14:42:15 < dongs> through inductor
2018-11-22T14:42:27 < zyp> yeah
2018-11-22T14:42:29 < dongs> you'd need special fuckery to make it actually disconect yea?
2018-11-22T14:42:43 < karlp> yeah, I guess i hadn't looked that far.
2018-11-22T14:43:09 < karlp> seems not very useful to enable/disable then
2018-11-22T14:43:24 < zyp> not if you want it to act as a power switch
2018-11-22T14:43:58 < zyp> but still useful to reduce consumption when the rail is idle

2018-11-22T18:45:06 < Sadale> I don't quite understand why there's a maximum input impedance. Couldn't we just push up the max value by reducing the ADC clock speed?
2018-11-22T18:47:12 < zyp> there's some leakage too, not just charging the cap
2018-11-22T18:50:55 < Sadale> ah... I see.
2018-11-22T18:52:58 < Sadale> true. That'd literally take forever to charge that :p
2018-11-22T18:53:08 < Sadale> In fact it'd never get charged because of what zyp said. leakage.

2018-11-22T19:16:20 < Steffanx> Enlighten us, kakimir 
2018-11-22T19:16:39 < Steffanx> Ah ofcourse:)
2018-11-22T19:16:56 < Steffanx> Lol.
2018-11-22T19:21:33 < kakimir> do connect EP and GND pin or not?
2018-11-22T19:21:44 < kakimir> EP is via stitched
2018-11-22T19:21:46 < kakimir> already
2018-11-22T19:22:11 < kakimir> I wonder is paste could cause some issues between GND and EP
2018-11-22T19:22:14 < kakimir> if
2018-11-22T19:25:43 < karlp> via stitches on exposed pads are to let heat out, not to drain solder.
2018-11-22T19:26:51 < kakimir> karlp: both
2018-11-22T19:34:28 < Steffanx> Rtfm kakimir
2018-11-22T19:34:43 < karlp> Cracki: sure they are, you can let hot air out.
2018-11-22T19:35:00 < karlp> it's not just about sinking heat into a ground plane.
2018-11-22T19:35:29 < karlp> there's even guidelines on how big they should be so that they don't get plugged with solder and _do_ make sure they let air out
2018-11-22T19:40:55 < englishman> kakimir: you will have ugly uneven reflow and probably be missing the solder fillet on that pin
2018-11-22T19:41:01 < englishman> but it will be electrically fine
2018-11-22T19:59:01 < kakimir> thanks englishman 
2018-11-22T19:59:15 < kakimir> didn't connect between gnd pin and ep

2018-11-22T20:32:02 < bitmask> should be 1A but at 12V input they recommend max of 150mA
2018-11-22T20:32:30 < bitmask> maybe I'll use a buck converter to supply 5V or so
2018-11-22T20:33:31 < bitmask> then I can just use the 5V from the buck to power the rgb leds too so I dont need to go through the onboard reg

2018-11-22T20:40:30 < bitmask> if I set the buck to 5V then I have to power via the 5V pin right? Vcc or Vin or whatever would have too big a voltage drop?
2018-11-22T20:45:13 < kakimir> next mad thing I try to do: use one buck boost regulator from 1S lipo to drive load with CC
2018-11-22T20:45:52 < kakimir> and the catch is: I try to use the very same regulator to charge that lipo from external powersource +5V
2018-11-22T20:47:39 < bitmask> yea thats what I said :) its a nano, I'll just power it on the 5V pin
2018-11-22T20:50:39 < bitmask> I feel better powering it from 5V instead of 12V too, its probably a clone, I'm not even sure
2018-11-22T20:51:04 < bitmask> actually it must be, it was cheap
2018-11-22T20:52:30 < bitmask> probably
2018-11-22T20:52:40 < bitmask> which is still good for 1A
2018-11-22T20:52:54 < bitmask> but I'll stick to the buck

2018-11-22T22:46:34 < kakimir> why there isn't 3layer pcbs?
2018-11-22T22:46:43 < zyp> 2.54 female headers will fit nicely in a 2.50 4-pin socket
2018-11-22T22:46:44 < kakimir> many times I could do with just 3
2018-11-22T22:46:51 < englishman> you can get 3layer but it will cost the same as 4l
2018-11-22T22:47:19 < zyp> because 3L doesn't simplify the process
2018-11-22T22:47:22 < kakimir> okay
2018-11-22T22:48:10 < zyp> 4L starts with a core with a layer on each side that's etched, then prepreg on each side, copper, etch again
2018-11-22T22:48:24 < zyp> two layers are etched at a time
2018-11-22T22:48:42 < zyp> 3L would require the same process, except one of the etching steps would only etch one layer
2018-11-22T22:50:44 < englishman> afaik the more common process is 2 fr4 etched and pressed with prepreg in between
2018-11-22T22:50:52 < kakimir> yes
2018-11-22T22:50:56 < englishman> so there is only one prepreg layer
2018-11-22T22:51:06 < englishman> but the other one exists too
2018-11-22T22:51:12 < kakimir> let's install kicad nightly
2018-11-22T22:52:30 < zyp> englishman, really? two thin cores with a thick prepreg layer in between?
2018-11-22T22:52:45 < kakimir> yes
2018-11-22T22:52:55 < kakimir> I have watched youtubes and they told so
2018-11-22T22:53:10 < kakimir> they were in pcb fab
2018-11-22T22:53:15 < englishman> https://i.imgur.com/RhNT4yK.png
2018-11-22T22:53:23 < zyp> I thought it were common for cores to be thick and prepreg to be thin
2018-11-22T22:54:16 < kakimir> is it common to have short failure throught thin core in other areas than close to vias englishman?
2018-11-22T22:54:22 < englishman> not sure, local bro has stacks and stacks of fr4 and prepreg in all thicknesses
2018-11-22T22:54:28 < kakimir> and no mechanical damage
2018-11-22T22:54:31 < zyp> either way, doesn't change the fact that two layers are etched at a time
2018-11-22T22:54:36 < englishman> right
2018-11-22T22:55:00 < englishman> there is only one additional image and exposure step for 4l vs 3l and that does not take much time

2018-11-23T01:17:10 < englishman> get it
2018-11-23T01:17:18 < englishman> avoid that filthy leaded leveller
2018-11-23T01:17:41 < englishman> your boards will look better and reflow easier

2018-11-23T01:21:05 < dongs> you can also opt for OSP if you're a cheap jew
2018-11-23T01:21:12 < dongs> OSP is almost as good as chink enig
2018-11-23T01:22:11 < jadew> what's OSP?
2018-11-23T01:22:26 < dongs> some organig something or other
2018-11-23T01:22:29 < dongs> its flat as enig
2018-11-23T01:22:34 < dongs> but cheaper cuz no gold
2018-11-23T01:22:43 < dongs> and just as good for paste spreading
2018-11-23T01:23:23 < jadew> "OSP (Organic Solderability Preservative) or anti-tarnish preserves the copper surface from oxidation by applying a very thin protective layer of material over the exposed copper usually using a conveyorized process."
2018-11-23T01:23:26 < jadew> interesting
2018-11-23T01:25:21 < dongs> anyway for china protos it works great
2018-11-23T01:25:29 < dongs> because you get smooth flat surface without gay shit
2018-11-23T01:25:39 < englishman> as long as you use it rather quick
2018-11-23T01:25:51 < englishman> or keep it sealed and dry and dont put your greasy fingers on it
2018-11-23T01:25:54 < dongs> (like hasl), and costs only slightly more than regular
2018-11-23T01:26:03 < dongs> yeah well, thats why i said protos
2018-11-23T01:26:08 < englishman> yea
2018-11-23T01:26:17 < dongs> besides its like ~months
2018-11-23T01:26:21 < dongs> not like days or hours
2018-11-23T01:26:21 < englishman> although if you have old shit
2018-11-23T01:26:24 < englishman> you can just get it replated
2018-11-23T01:26:28 < englishman> and its good as new
2018-11-23T01:26:41 < dongs> if you didnt use your protos in a few months you probly didnt ned them anyway
2018-11-23T01:26:52 < dongs> and probly just autismed
2018-11-23T01:26:57 < englishman> idk it happens

2018-11-23T02:10:11 < jadew> must be in km/h
2018-11-23T02:11:04 < jadew> ah, 150 miles = only 240 km
2018-11-23T02:11:07 < jadew> I guess it's ok
2018-11-23T02:12:14 < jadew> for a moment there, I forgot the imperial system is completely stupid, so I thought miles and km had the same ratio as inches and cm
2018-11-23T02:13:04 < kakimir> how

2018-11-23T02:33:27 < jadew> I'd make the sheet metal smaller by "tollerance" (parameter)

2018-11-23T10:38:11 < mads-> I have a STM32F103C8T6 on my blackpill. The specs says it has 64 or 128 KB flash. How do I check which it is? Because if I program on Arduino IDE with 64 it tells me it is too small when compiling a program with FastLed.h

2018-11-23T10:45:30 < mads-> Roger Clark also writes that it should have 128 ( https://www.stm32duino.com/viewtopic.php?t=1347 ) 
2018-11-23T10:46:09 < mads-> What would happen if I compile with 128 and upload it to my black pill? Theoretically. 
2018-11-23T10:46:50 < mads-> I have a st-link. And when I program my black pill I also 'verify'
2018-11-23T10:47:11 < mads-> So shouldn't that talk for that it all is written (and read) to the black pill?

2018-11-23T11:02:01 < Steffanx> I believe there were stories about the 64k version actually had 128k mads- 
2018-11-23T11:02:28 < Steffanx> Dongs can tell you all about it. F103 is his favourite mcu
2018-11-23T11:03:29 < Steffanx> If it has 128k you will probably be able to flash and run it
2018-11-23T11:04:59 < mads-> Steffanx: I will try to ping him :) Could be cool. I would love to use the FastLed library. Else I will have to find something else for my WS2812b

2018-11-23T11:32:36 < mads-> Steffanx: No. I tried some stuff yesterday, but I only found that forum post today. And now I am at work. Just trying to gather some information before tonights attempts.
2018-11-23T11:33:40 < dongs> all C8 has 128k
2018-11-23T11:33:47 < dongs> but FLASH_SIZE register reports 64.
2018-11-23T11:33:52 < dongs> so you can just ignore it.
2018-11-23T11:34:12 < dongs> my guess is there's some slight chance that 64k stuff had a bank that failed during factory tests and it became like that.
2018-11-23T11:34:50 < dongs> as long as you force flash size and verify (and don't mind the remote chance that it might not work at some point), there's no problem.
2018-11-23T11:35:21 < dongs> not sure what the fuck that has to do with 'fastled' tho
2018-11-23T11:35:37 < dongs> figuring out how to DMA WS2182 stuff out of TIM1 is not hard
2018-11-23T11:35:47 < dongs> certainly doesn't need a 'librnary'
2018-11-23T11:37:26 < dongs> fusion360 eh
2018-11-23T11:37:34 < dongs> should i learn that or solidcucks?

2018-11-23T12:00:41 < qyx> what is a synchronous slave mode
2018-11-23T12:00:47 < dongs> Haohmaru: atmel software framework is not awful, if it supports that chip chances are all the shit will work out of the box
2018-11-23T12:00:50 < dongs> wiht atmel studio shite.

2018-11-23T12:05:00 < qyx> yes, SPI peripheral can handle that
2018-11-23T12:05:04 < dongs> get the fuck out
2018-11-23T12:05:27 < qyx> what, I am using that on ~10 baords
2018-11-23T12:05:39 < qyx> F0, F3 and L4
2018-11-23T12:06:23 < qyx> you are not obliged to use NSS for framing
2018-11-23T12:06:53 < qyx> so you want the clock to run freely and transmit when there are data available
2018-11-23T12:07:33 < qyx> then I don't get it
2018-11-23T12:07:42 < qyx> how are you supposed to mark start of the byte
2018-11-23T12:09:27 < qyx> so you are using start/stop bits in async mode too?

2018-11-23T12:15:20 < qyx> so far I couldn't find any reference on the interwebs showing that someone is using async protocol (start/stop) with data/xck sync usart and without any framing signal
2018-11-23T12:23:00 < jpa-> IIRC STM32 USART in synchronous mode sends the start/stop bits, but doesn't clock them, and i think the receiver doesn't care about them
2018-11-23T12:24:15 < jpa-> i haven't ever seem synchronous USART actually being used
2018-11-23T12:24:55 < qyx> according tot he datasheet the atmel part clocks start/stop in sync mode and expects them in slave mode
2018-11-23T12:25:20 < qyx> stm32 rm doesn't show it, it shows only the data being clocked out
2018-11-23T12:26:18 < qyx> it is literally weird then
2018-11-23T12:26:27 < jpa-> i'd just use SPI, even though STM32 SPI in slave mode is sometimes slightly tricky
2018-11-23T12:26:41 < jpa-> atleast it is standard :P
2018-11-23T12:27:08 < qyx> thats not the problem
2018-11-23T12:28:51 < Haohmaru> while the usart is uber fancy and works fine
2018-11-23T12:31:46 < karlp> so, you want to use as many wires as  spi, and you wantt o have the clock line free running, beucase EM emissionsis awesome,

2018-11-23T15:14:57 < Thorn> has anyone read The Wages of Destruction?
2018-11-23T15:17:38 < Sadale> seriously, don't use 9gag.
2018-11-23T15:18:21 < Sadale> In the past they removed others watermark and stamp their own on it. They also modified the displayed creation time of the work so that it seems like that they're the source of the meme. I'm not sure if they're still doing that, tho
2018-11-23T15:19:20 < Sadale> There're a lot of other alternatives of 9gag. Perhaps they also stamp their watermark on it. But at least those other sites won't claim the ownership of the meme that they didn't make.
2018-11-23T15:19:52 < Sadale> So please use other websites for meme source. Thanks.
2018-11-23T15:20:55 < qyx> wat
2018-11-23T15:28:15 < englishman> meme ownership is srs
2018-11-23T15:32:04 < Steffanx> Lol Sadale. I just googled for some random leaf diesel charger. This was the best/first.
2018-11-23T15:32:17 < Steffanx> I love you too.
2018-11-23T15:32:26 < Sadale> Steffanx, I see :3
2018-11-23T15:32:42 < englishman> thats exactly what i was going to have to o
2018-11-23T15:32:43 < englishman> do
2018-11-23T15:34:17 < englishman> range is really surprisingly poor in winter
2018-11-23T15:35:25 < Steffanx> Hows the chinaland today, Sadale 
2018-11-23T15:35:38 < Sadale> nothing much is going on here I guess. :3
2018-11-23T15:40:46 < Steffanx> Still enjoying your free time?
2018-11-23T15:41:35 < qyx> englishman: when the leaf runs out of power, is there any aux battery to power the onboard electronics? or everything is completely dead?
2018-11-23T15:41:49 < englishman> yes. all electric cars have 12v batteries
2018-11-23T15:42:18 < englishman> they are recharged from the traction battery, but also power the contactors for the traction battery
2018-11-23T15:42:57 < englishman> so it's pretty safe. if you disconnect the 12v battery, like at a regular garage going in for service that might not know shit about electric cars, it won't start up and drive away
2018-11-23T15:43:23 < englishman> when the battery died, it didnt let me shift out of neutral anymore. and that was it
2018-11-23T15:51:02 < dongs> oh i missed autisming with sadale in HK
2018-11-23T15:51:11 < Sadale> dongs, :c
2018-11-23T15:51:17 < dongs> i probly coulda done it if I didnt fuck my hand up on sunday
2018-11-23T15:51:25 < dongs> or was it monday 
2018-11-23T15:51:26 < Sadale> dongs, wanna have a meetup? I could be your tour guide as I can speak Cantonese well. :p
2018-11-23T15:51:36 < Sadale> dongs, I meant when you visit Hong Kong the next time :3
2018-11-23T15:51:40 < dongs> i could use a guide cuz i couldnt find anything worth eating
2018-11-23T15:51:54 < dongs> was looking for some nice icream place
2018-11-23T15:51:56 < dongs> found: nothing
2018-11-23T15:52:07 < Sadale> I think I know a few icecream stores.
2018-11-23T15:52:34 < Sadale> There're some inside most larger scale shopping centers.
2018-11-23T15:52:44 < dongs> i think those are probly gay and generic
2018-11-23T15:52:49 < dongs> im not looking for haagen dazs type shit
2018-11-23T15:53:03 < Sadale> No. Not haagendazs.
2018-11-23T15:53:15 < Sadale> It's just normal icecream balls. Depending on the exact place, it can be cheap.
2018-11-23T15:53:26 < dongs> thats boring too
2018-11-23T15:53:39 < Sadale> I think I had one somewhere that I got 5 balls of icecream for around HKD$15 or so
2018-11-23T15:53:40 < dongs> im looking more like some parfait-style stuff with fresh fruit and some icecream and shit mixed in
2018-11-23T15:53:44 < qyx> icecream is there on every corner
2018-11-23T15:53:45 < Sadale> ow
2018-11-23T15:53:51 < Sadale> I'm sorry then. I'm not aware of any of those.
2018-11-23T15:54:09 < dongs> my pal said there was something but then shut up when i asked where exactly
2018-11-23T15:54:36 < Sadale> There may be some. But I just don't know where.
2018-11-23T15:54:45 < Sadale> dongs, I didn't know that's the sort of icecream you were looking for
2018-11-23T15:55:31 < Sadale> I thought that you were cool with any sort of icecream... :c
2018-11-23T15:55:39 < dongs> any sort is boring
2018-11-23T15:55:44 < veverak> hmm, how pain in the ass is to read some camera sensor?
2018-11-23T15:55:51 < Sadale> dongs, up for a challenge of having spicy food? That's fun :P
2018-11-23T15:55:52 < veverak> I figured I would like optical flow detection
2018-11-23T15:56:01 < dongs> veverak: enough pain to not bother with on stm32
2018-11-23T15:56:08 < veverak> camera + stm32 sounds like what I want

2018-11-23T15:56:18 < dongs> fuck spicy food too
2018-11-23T15:56:27 < Sadale> lol
2018-11-23T15:56:38 < veverak> qyx: tried it?
2018-11-23T15:56:40 < Sadale> I like them. Except that my belly can't stand for that xD
2018-11-23T15:56:41 < veverak> dongs: tried it?
2018-11-23T15:56:50 < veverak> it's not like high ress or anything
2018-11-23T15:56:56 < dongs> veverak: yeah, i hoked up some 5mp thing to stm32f407? or so via DCMI
2018-11-23T15:56:58 < dongs> and gave up after a while
2018-11-23T15:57:01 < veverak> I see
2018-11-23T15:57:02 < dongs> you can only use it in jpeg mode
2018-11-23T15:57:04 < dongs> and
2018-11-23T15:57:10 < veverak> 5mp seems like overkill
2018-11-23T15:57:14 < dongs> you dont have enough ram to get each frame + to do something with it
2018-11-23T15:57:19 < Sadale> dongs, try something called "重慶酸辣粉". They're sour and spicy.
2018-11-23T15:57:21 < qyx> veverak: yes 2MP OV2640 in jpeg mode
2018-11-23T15:57:25 < veverak> want it for robot localization

2018-11-23T15:57:50 < dongs> veverak: why not actually use optical flow mice shit
2018-11-23T15:57:51 < veverak> *thanks
2018-11-23T15:57:53 < dongs> that are like SPI or something

2018-11-23T15:58:00 < qyx> some old codez
2018-11-23T15:58:12 < dongs> > without using dcmi
2018-11-23T15:58:21 < qyx> yeah
2018-11-23T15:58:30 < qyx> I have a dcmi code somewhere too
2018-11-23T16:02:10 < qyx> veverak: I'll commit&push F4/DCMI using libopencm3 if you are interested

2018-11-23T16:18:08 < dongs> https://gfycat.com/pastwealthyflee ah this is why judew hasnt been around
2018-11-23T16:24:36 < tctw> dongs, please don't post content like that in this channel.
2018-11-23T16:25:05 < jpa-> yeah, #ugfx is for those links
2018-11-23T16:25:22 < dongs> i thought he moved to #uguufx
2018-11-23T16:25:45 < englishman> you cant even see what it is
2018-11-23T16:25:52 < englishman> looks like soldiers airing out a blanket
2018-11-23T16:26:05 < englishman> clearly romanian camera quality
2018-11-23T16:27:01 < Steffanx> Look better.
2018-11-23T16:27:02 < dongs> im taking a wild guess here that electrocutat probly means he was getting smoked by electricity
2018-11-23T16:27:53 < englishman> i agree, poor ##stm32 content
2018-11-23T16:27:57 < englishman> maybe if it was 4k
2018-11-23T16:28:05 < dongs> ill do better next time
2018-11-23T16:28:11 < englishman> however, coming from tectu, who posts nothing at all, a rather strange request
2018-11-23T16:35:07 < jadew> yeah, that's what it means
2018-11-23T16:35:35 < jadew> they didn't even try CPR
2018-11-23T16:35:47 < dongs> i dont even know what the fuck is going on there
2018-11-23T16:35:54 < dongs> i just saw tank and blanket
2018-11-23T16:36:02 < jadew> https://www.youtube.com/watch?v=WajYZoYOmRs
2018-11-23T16:36:03 < dongs> quality is typical romanian sellfone
2018-11-23T16:36:14 < jadew> obviously a guy inside a tank got electrocuted
2018-11-23T16:36:18 < jadew> but I don't understand how
2018-11-23T16:36:32 < jadew> I didn't know they had that high voltages around
2018-11-23T16:36:38 < jadew> maybe from the radio stuff?
2018-11-23T16:36:54 < dongs> i donno about inside, maybe he knocked over one of those poles
2018-11-23T16:36:57 < dongs> that there seems to be so many of
2018-11-23T16:36:58 < dongs> for trains?
2018-11-23T16:37:07 < jadew> oh, possible
2018-11-23T16:37:29 < jadew> I'll look into it
2018-11-23T16:37:30 < jadew> give me a sec
2018-11-23T16:38:36 < jadew> apparently he touched some high voltage wires on those poles
2018-11-23T16:38:55 < dongs> wonder if he was standing on the tank
2018-11-23T16:38:58 < dongs> and touched
2018-11-23T16:39:00 < dongs> and fell inside
2018-11-23T16:39:05 < dongs> or like head sticking out
2018-11-23T16:39:06 < dongs> or wahtever
2018-11-23T16:39:15 < jadew> the witnesses say he was thrown into the air like a doll
2018-11-23T16:39:36 < jadew> he probably fell in there after the accident
2018-11-23T16:39:54 < dongs> i saw 150kV substation right on the sside of teh street in HK
2018-11-23T16:40:04 < dongs> ther was 'do not touch' and shit warnings all over
2018-11-23T16:40:30 < dongs> depending on trains there could be some kV in there
2018-11-23T16:40:32 < jadew> and yeah, it appears he stood up on the tank and touched the wire, but they don't say how he touched it
2018-11-23T16:40:33 < dongs> jap shit is like 25kV i think
2018-11-23T16:43:13 < jadew> yep, 25 kV here as well
2018-11-23T16:43:33 < jadew> no wonder he cought fire
2018-11-23T16:44:50 -!- jsoft [~jsoft@unaffiliated/jsoft] has quit [Ping timeout: 244 seconds]

2018-11-23T16:56:13 < dongs> there was a vid where some indian or somesthin dude was just casually strolling around the train roof
2018-11-23T16:56:20 < dongs> then decided to grab the overhead wire for no reason
2018-11-23T16:56:35 < dongs> https://www.dailymotion.com/video/x9i793 ya this
2018-11-23T16:59:55 < jadew> instant fire
2018-11-23T17:00:14 < jadew> I wonder if anyone survived this
2018-11-23T17:00:38 < jadew> there was that clip with the painters that got electrocuted from 5 kV wires and one of them walked away
2018-11-23T17:00:46 < jadew> (got electrocuted twice)
2018-11-23T17:01:01 < dongs> the one where theypre pushing some scaffolding?
2018-11-23T17:01:05 < jadew> but 25 kV seems to be more brutal
2018-11-23T17:01:08 < jadew> yeah
2018-11-23T17:01:15 < dongs> yeah seen that
2018-11-23T17:02:12 < dongs> https://english.kyodonews.net/news/2018/06/c568e9157f4a-feature-japanese-schools-introduce-lgbt-friendly-uniforms.html
2018-11-23T17:03:11 < jadew> way to ruin the japanese culture
2018-11-23T17:03:13 < zyp> seems reasonable enough
2018-11-23T17:03:15 < karlp> anyeone here ever looked at rj point 5, or seen any gear with them?
2018-11-23T17:03:25 < dongs> wot?
2018-11-23T17:03:38 < karlp> this stuff: https://www.te.com/usa-en/products/connectors/modular-jacks-plugs/rj-point-five-connectors.html?tab=pgp-story
2018-11-23T17:03:39 < dongs> oh
2018-11-23T17:03:44 < dongs> yeah those weird halfsize ethernet shits
2018-11-23T17:04:03 < zyp> haven't heard of before now, looks like a crossover between RJ45 and usb-A
2018-11-23T17:04:42 < karlp> yeah, I saw it a few years ago, saw it again today, 
2018-11-23T17:04:43 < dongs> im certain if there's some governmetn that feels to be locked into single supplier of plugs and cables and sockets, tehy'll pick this for their next IT project
2018-11-23T17:04:53 < karlp> oh, it's made by multiple people
2018-11-23T17:04:59 < karlp> bel makes it too, at least.
2018-11-23T17:05:19 < zyp> that page claims «RJ point five is a trademark.» though
2018-11-23T17:05:21 < jadew> I've seen HDMI and USB mixtures
2018-11-23T17:05:39 < jadew> my laptop has a port like that
2018-11-23T17:05:54 < zyp> also, cat5e rating seems a bit outdated
2018-11-23T17:06:06 < dongs> iv'e seen esata/usb
2018-11-23T17:06:11 < dongs> cant say ive seen hdmi/usb
2018-11-23T17:06:22 < jadew> hmm, maybe it's e-sata?
2018-11-23T17:06:27 < jadew> I have to check
2018-11-23T17:06:30 < dongs> that would be my guess
2018-11-23T17:06:43 < jadew> looked like HDMI, but I haven't studied it much
2018-11-23T17:06:45 < qyx> karlp: considering them for the rs485/eth stuff?
2018-11-23T17:06:53 < dongs> https://en.wikipedia.org/wiki/ESATAp
2018-11-23T17:06:59 < karlp> well, not really seriously, I don't think it has a chance of really being readily available.
2018-11-23T17:07:10 < qyx> use M12 as a real pro
2018-11-23T17:07:15 < karlp> fuck off :)
2018-11-23T17:07:18 < qyx> :>
2018-11-23T17:07:23 < dongs> some really old laotppos use to thave that
2018-11-23T17:07:57 < jadew> dongs, you're right, it was e-sata
2018-11-23T17:08:10 < karlp> apparently digikey just callss it "HD" https://www.digikey.com/product-detail/en/stewart-connector/RJP50010AB-A/380-1294-ND/4049990
2018-11-23T17:08:43 < dongs> i wonder if china can crimp those
2018-11-23T17:08:44 < qyx> $30 meh
2018-11-23T17:08:49 < dongs> the tool is probly like $500 for it
2018-11-23T17:08:55 < dongs> just like your t ypical molex crimping tool
2018-11-23T17:09:09 < zyp> qyx, my workshit is all M12
2018-11-23T17:09:15 < dongs> whats M12
2018-11-23T17:09:24 < qyx> eu industrial stuff
2018-11-23T17:09:28 < zyp> round industrial screw-on connectors
2018-11-23T17:09:39 < dongs> hah
2018-11-23T17:09:41 < dongs> 3 pin?
2018-11-23T17:09:47 < qyx> anypin
2018-11-23T17:09:47 < zyp> varies
2018-11-23T17:10:00 < dongs> oih the M thing is just t hat its screw-on and same sizE?
2018-11-23T17:10:05 < qyx> they are used for fieldbuses, ethernet, power, dio, analol
2018-11-23T17:10:05 < zyp> correct
2018-11-23T17:10:22 < dongs> how about dmx
2018-11-23T17:10:25 < zyp> https://bin.jvnv.net/file/1kb6r.jpg <- this sort of shit
2018-11-23T17:10:51 < zyp> green ones are ethernet, yellow one is an 8-pin with various signals
2018-11-23T17:11:01 < dongs> -proing
2018-11-23T17:11:04 < zyp> two unconnected ones in the back are power
2018-11-23T17:11:18 < qyx> interesting enclosure on the left
2018-11-23T17:11:23 < qyx> *enclosures
2018-11-23T17:11:30 < dongs> that looks like some DIN crap
2018-11-23T17:11:30 < zyp> that's kunbus stuff
2018-11-23T17:11:34 < qyx> is it your device or some generic ethernet thing
2018-11-23T17:11:34 < zyp> yeah
2018-11-23T17:11:48 < zyp> it's a kunbus fieldbus gateway thing
2018-11-23T17:11:51 < qyx> looks like pheonix contact enclosures
2018-11-23T17:12:22 < dongs> is thjat a legit jlink
2018-11-23T17:12:24 < dongs> in background
2018-11-23T17:12:29 < zyp> https://www.kunbus.com/modular-gateways.html <- this shit
2018-11-23T17:12:37 < zyp> yeah, it's mine
2018-11-23T17:13:02 < zyp> well, my work's, but still
2018-11-23T17:13:38 < qyx> profibug
2018-11-23T17:14:20 < zyp> the shit I'm working on is a distributed system, which forms its own fieldbus stuff, and then it's using that gateway shit to talk to customer systems
2018-11-23T17:14:33 < karlp> you can get singles too, relatively cheap: https://www.digikey.com/product-detail/en/stewart-connector/RJP5-10-0003/380-1288-ND/4331780
2018-11-23T17:14:46 < dongs> by "
2018-11-23T17:14:51 < dongs> can get" you mean, qty 0
2018-11-23T17:14:55 < dongs> with months of lead time
2018-11-23T17:14:58 < qyx> its own fieldbus == over ethernet?
2018-11-23T17:15:05 < zyp> karlp, hey, there you have your sideways ethernet connector
2018-11-23T17:15:09 < zyp> qyx, yeah
2018-11-23T17:15:21 < zyp> «own» meaning isolated from the customer system it integrates with
2018-11-23T17:15:21 < dongs> at that point cant you just use failwire connector
2018-11-23T17:15:40 < karlp> zyp: yeah, exactly :) but not reallllly very interoperable honestly.
2018-11-23T17:15:40 < dongs> ah failwire is only 2 pairs
2018-11-23T17:15:46 < dongs> well, i guess you could do 100m ethernet with that
2018-11-23T17:15:53 < karlp> my last 20 minutes have shown me that this is possible, but... not going to look further at it.
2018-11-23T17:16:16 < karlp> what's failwire?
2018-11-23T17:16:20 < qyx> you could still use screw terminals for it
2018-11-23T17:16:20 < dongs> firewire? lol
2018-11-23T17:16:32 < zyp> dongs, the M12 D-code connectors are also only two pairs, and yes we're running 100m on that
2018-11-23T17:16:38 < karlp> qyx: screw terminals for what? 
2018-11-23T17:16:43 < qyx> ethernet of course
2018-11-23T17:16:45 < dongs> http://pinouts.ru/Slots/ieee1394_pinout.shtml
2018-11-23T17:16:45 < zyp> there's also M12 X-code for gigabit, but we don't need that
2018-11-23T17:17:01 < karlp> yeah, fuck that, m12 screw is ~as big or bigger than an rj jack anyway 
2018-11-23T17:17:17 < dongs> 4 pin firewire is tiny
2018-11-23T17:17:28 < zyp> karlp, not advocating M12 for you
2018-11-23T17:17:34 < karlp> no, qyx is :)
2018-11-23T17:17:41 < zyp> but for my workshit it's good
2018-11-23T17:17:43 < qyx> just trolling
2018-11-23T17:17:48 < qyx> wheres kakimir
2018-11-23T17:17:50 < karlp> firewire to rj45 cabling woudlall be custom too.
2018-11-23T17:17:54 < qyx> there is serious lack of smas
2018-11-23T17:18:03 < karlp> just curiosu whether anyone had even _seen_ this rjp5 stuff.
2018-11-23T17:18:14 < zyp> never heard of until you mentioned it :)
2018-11-23T17:18:25 < qyx> same here
2018-11-23T17:19:01 < qyx> but once I discovered some super low profile RJ45
2018-11-23T17:19:11 < zyp> there's plenty of those
2018-11-23T17:19:24 < zyp> stuff that mounts in a slot of the board and shit
2018-11-23T17:19:35 < dongs> yeah the old XJACK style shit
2018-11-23T17:19:43 < qyx> something like this http://img.everychina.com/nimg/d8/fc/539a6ffabf26515c6838d5e7e4d8-300x300-0/hulyn_very_low_profile_rj45_1x1_jack_shielded_rj45_modular_jack_through_hole_type_dip_with_leds.jpg
2018-11-23T17:19:52 < dongs> seen those too
2018-11-23T17:20:03 < dongs> nucelo with ethernet uses a similar mid-mount thing
2018-11-23T17:20:30 < zyp> one of my pocket routers for travel got something like that
2018-11-23T17:21:12 < karlp> then there's this shit: http://www.nu45.org/white-paper
2018-11-23T17:21:32 < dongs> oh boy. block-chain backed RJ45 with a ~white paper~ ?
2018-11-23T17:21:33 < dongs> sign me up.
2018-11-23T17:21:37 < zyp> haha
2018-11-23T17:21:59 < dongs> looks like usb-c clone
2018-11-23T17:22:10 < karlp> no idea on timeframes, but yeah.
2018-11-23T17:22:19 < dongs> seriosuly isntead of wasting time just make USB-C ehternet alternative mode
2018-11-23T17:22:20 < dongs> and done
2018-11-23T17:22:25 < karlp> if usb-c ethernet stuff was more prevalent, usb-c would be handy
2018-11-23T17:22:35 < zyp> yeah
2018-11-23T17:22:36 < karlp> it's either autism or javascript :)
2018-11-23T17:22:49 < karlp> usb-c ethernet is specced, just not well implemented and deployed right?
2018-11-23T17:22:56 < zyp> is it?
2018-11-23T17:23:01  * karlp shrugs
2018-11-23T17:23:14 < karlp> they have display port, and ethernet over hdmi, surely they have ethernet over usbc?
2018-11-23T17:23:15 < dongs> http://www.ieee802.org/3/email_dialog/msg00262.html
2018-11-23T17:23:22 < zyp> I mean, I'd even ask if there's much of a point
2018-11-23T17:24:02 < zyp> you still need to talk some usb to handle negotiation, so why not just do some ethernet over usb class with plain usb-c instead?
2018-11-23T17:24:12 < dongs> zyp, altmode is done wiht pd
2018-11-23T17:24:17 < dongs> doesnt need usb
2018-11-23T17:24:30 < dongs> well pd = i mean comms over cc shit
2018-11-23T17:24:32 < zyp> oh, I thought it used the usb2 lane with billboard class for that
2018-11-23T17:24:34 < dongs> usb billboard stuff is optional
2018-11-23T17:24:36 < dongs> no
2018-11-23T17:24:41 < dongs> primary way is by cc
2018-11-23T17:24:58 < zyp> okay, that sounds more reasonable
2018-11-23T17:25:24 < zyp> wonder how well that gets along with galvanic isolation requirements
2018-11-23T17:25:32 < dongs> and there's bunch of single-purpose chips that have CC analog frontend and some shitty mcu in them to negotiate stuff like altmode 
2018-11-23T17:25:41 < zyp> I guess it'd violate spacing requirements
2018-11-23T17:26:06 < zyp> unless you made the entire CC circuit isolated from your main circuit
2018-11-23T17:26:25 < zyp> which again has a bunch of hassles regarding power isolation
2018-11-23T17:27:12 < zyp> handling rotation of the plug should be easy though, since every modern phy handles auto mdi-x
2018-11-23T17:54:00 < dongs> https://panasonic.jp/cns/pc/products/rz6c/img/top/feature04_top.png lol fucking panasonic
2018-11-23T17:54:03 < dongs> 2018 model laptop
2018-11-23T17:54:10 < dongs> still has VGA connector
2018-11-23T17:54:16 < aandrew> lol
2018-11-23T17:54:19 < dongs> at least they got rid of that fucking round touchpad
2018-11-23T17:54:28 < aandrew> I bought a shitty shitty acer 10 one
2018-11-23T17:54:40 < aandrew> 2GB RAM 16GB eMMC, runs win10-32bit
2018-11-23T17:54:51 < aandrew> need to return it to get teh 4GB/64GB one though, this is too light for win10
2018-11-23T17:55:00 < aandrew> but under $200 which is why I got it
2018-11-23T17:55:12 < qyx> 12GB emmc?
2018-11-23T17:55:15 < qyx> 16
2018-11-23T17:55:31 < qyx> not enough for win10 and altium probably
2018-11-23T17:55:36 < aandrew> no no no
2018-11-23T17:55:39 < aandrew> this isn't for actual dev work
2018-11-23T17:55:45 < aandrew> I just need a machine running win10 to test some shit
2018-11-23T17:55:54 < aandrew> not interested in actually running win10 for anything useful
2018-11-23T17:56:02 < aandrew> but I can drag this with me as it's small
2018-11-23T17:56:25 < qyx> a more serious question, is there any stm32 with dual sdmmc?
2018-11-23T17:56:39 < qyx> I didn't find a way to filter them
2018-11-23T17:57:39 < dongs> H7 apparently has
2018-11-23T17:57:47 < dongs> and F7x3
2018-11-23T17:58:13 < dongs> apparently ouy can filter it
2018-11-23T17:58:15 < dongs> in cubemx
2018-11-23T17:58:18 < dongs> just checkbox sdmmc
2018-11-23T17:58:19 < qyx> oh
2018-11-23T17:58:20 < dongs> and type 2
2018-11-23T17:58:23 < dongs> into the textbox
2018-11-23T17:58:33 < dongs> https://community.st.com/sfc/servlet.shepherd/version/renditionDownload?rendition=ORIGINAL_Png&versionId=0680X000006qOdf&operationContext=CHATTER&contentId=05T0X00000NPMW7
2018-11-23T17:58:36 < qyx> I'll download it then!
2018-11-23T17:58:51 < qyx> ty
2018-11-23T18:00:16 < dongs> i'm no so sure of significance of SDIO vs SDMMC
2018-11-23T18:00:46 < aandrew> that's a really good question
2018-11-23T18:01:02 < aandrew> my guess (and only a guess) is that it's either 4-bit mode or variable voltage rail
2018-11-23T18:01:03 < dongs> http://www.st.com/resource/en/product_training/stm32l4_peripheral_sdmmc.pdf apparently its a thing
2018-11-23T18:01:25 < dongs> sounds like 2.0 of sdio peripheral
2018-11-23T18:01:34 < dongs> and up to 8 bit mode
2018-11-23T18:01:39 < dongs> where as sdio was only 4bit max?
2018-11-23T18:02:35 < dongs> you could use 8bit mode for eMMC as well
2018-11-23T18:02:44 < dongs> gigabytes of space on your stm32
2018-11-23T18:03:12 < qyx> or I may just use SPI and F0
2018-11-23T18:04:16 < aandrew> hm, I didn't think there were enough pins for 8 bit mode
2018-11-23T18:04:20 < aandrew> on sdxc
2018-11-23T18:04:24 < dongs> ?
2018-11-23T18:04:28 < dongs> 8bit is for emmc
2018-11-23T18:04:43 < dongs> sdxc is 4 bit max, yes
2018-11-23T18:04:55 < qyx> I have that sama5d27 som EK here
2018-11-23T18:04:56 < dongs> they tried to do some bullshti where they put pcie or sata or something on sd cards
2018-11-23T18:04:59 < dongs> but that shit died
2018-11-23T18:05:01 < qyx> and it has SD slot
2018-11-23T18:05:11 < qyx> with two resistor netowkrs
2018-11-23T18:05:22 < qyx> and 13 pins
2018-11-23T18:06:03 < qyx> schematic shows there are 8 bits going inside
2018-11-23T18:06:13 < qyx> it is marked as "SD/MMCplus"

2018-11-23T18:07:22 < dongs> if you haven't heard of it by now
2018-11-23T18:07:26 < dongs> its probly dead.

2018-11-23T18:11:05 < dongs> also nice fucking link god damn
2018-11-23T18:12:08 < dongs> CubeMX is a nice tool but it lags behind CubeF7. Version 4.22.1 as well.
2018-11-23T18:12:08 < dongs> Learn to switch like I did. You spend more hours in debugging as in 
2018-11-23T18:12:09 < dongs> building a new project without a code generator.
2018-11-23T18:12:10 < dongs> uihhhhh
2018-11-23T18:12:15 < dongs> there's "CubeM7" now?
2018-11-23T18:12:32 < marble_visions> dunno if i've asked, has anyone found a way to clear the spi shift register in stm32l03x without turning the spi peripheral off and on again?
2018-11-23T18:12:41 < dongs> yes
2018-11-23T18:12:45 < dongs> is that the one wiht SPI fifo?
2018-11-23T18:12:55 < marble_visions> no fifo, only DR 
2018-11-23T18:13:28 < marble_visions> but i'm using DMA so there's always one byte that gets shifted in
2018-11-23T18:13:33 < dongs> yes but d you have SPI_RxFIFOThresholdConfig
2018-11-23T18:13:38 < dongs> (or similar shit
2018-11-23T18:13:44 < marble_visions> dongs: lemme see
2018-11-23T18:14:49 < dongs>     while (SPI2->SR & SPI_SR_FRLVL)
2018-11-23T18:14:50 < dongs>         SPI_I2S_ReceiveData16(SPI2);
2018-11-23T18:14:53 < dongs> also this
2018-11-23T18:15:00 < dongs> is waht I do after DMA
2018-11-23T18:15:02 < dongs> to clear that crap out
2018-11-23T18:15:48 < dongs> you can do that before DMA as well
2018-11-23T18:16:02 < dongs> anyway, this all asumes that L0shit has the new SPI periperhal with fifo
2018-11-23T18:16:05 < dongs> same as on F3/F0 etc.
2018-11-23T18:16:12 < marble_visions> spi features: 1-byte/word transmission and reception buffer with DMA capability: Tx and Rx requests, and I see the tx/rx "buffers" on the diagram as well, lemme check what's the FRLVL flag doing

2018-11-23T18:16:33 < dongs> if you dont have frlvl then its the old spi with out fifo
2018-11-23T18:16:38 < dongs> and then i donno
2018-11-23T18:17:04 < marble_visions> so l0 is older than f0/f3? 
2018-11-23T18:17:22 < dongs> l0 is M3 isnt it?
2018-11-23T18:17:29 < dongs> ah no m0+
2018-11-23T18:17:39 < dongs> i donno what teh fuck they're doing when they decide what peripehral goes where
2018-11-23T18:17:45 < dongs> maybe it has to do with pwoer consumption or wahtever.
2018-11-23T18:18:04 < dongs> L1 is the ancient m3 stuff
2018-11-23T18:19:03 < dongs> https://github.com/Ell-i/Runtime man some people have way too much time on ther ands
2018-11-23T18:19:46 < marble_visions> dongs: no such flag, guess off/on is the only way out
2018-11-23T18:19:57 < marble_visions> which i'm doing, but it's still bad form IMO
2018-11-23T18:20:14 < karlp> aandrew: have you considered using ms's internet explorer test VMs?
2018-11-23T18:20:16 < dongs> yeah. then i dont know. can't you just do "SPIx->DR;" in code before doing whatever to flush it out?
2018-11-23T18:20:19 < dongs> incase theres crap in it
2018-11-23T18:20:25 < dongs> karlp: ive used htem
2018-11-23T18:20:26 < dongs> why?
2018-11-23T18:21:27 < marble_visions> dongs: good idea, i'll see if that clears the TXE/RXNE flags
2018-11-23T18:22:05 < dongs> i mean,, my non-DMA SPI transaction is something like this
2018-11-23T18:22:06 < dongs> http://bcas.tv/paste/
2018-11-23T18:22:08 < dongs> er

2018-11-23T18:22:21 < dongs> i think cube/wahtever has similar shit
2018-11-23T18:22:22 < karlp> dongs: yeah, I've used them too, but aandrew was talkingabout needing to buy a win 10 laptop just to test stuff out.
2018-11-23T18:22:32 < karlp> I was wondering whether one of those vms was enough for what they needed
2018-11-23T18:22:35 < dongs> heh okay so he buys a $200 piece of shit
2018-11-23T18:22:38 < dongs> with 2gb ram
2018-11-23T18:22:41 < dongs> good luck testing shit on that

2018-11-23T22:26:52 < tpw_rules> i bought the bare modules and made my own board. it was a pain to solder them but they work great
2018-11-23T22:27:12 < invzim> how do you physically mount the display, glue?
2018-11-23T22:27:28 < tpw_rules> it has foam on the back and sits in a hole in the case

2018-11-23T23:03:23 < englishman> bigger tray
2018-11-23T23:03:24 < englishman> cool
2018-11-23T23:03:32 < englishman> did you flash the avr with opensores
2018-11-23T23:04:16 < englishman> mads-, could you tell us what a blackpill is
2018-11-23T23:21:50 < englishman> https://www.youtube.com/watch?v=WdDi1haA71Q
2018-11-23T23:22:30 < englishman> what a bunch of hacks
2018-11-23T23:22:41 < mads-> englishman: Oh sorry, I thought that was common terminology. It's a STM32F103C8T6 
2018-11-23T23:22:49 < mads-> https://forum.hobbycomponents.com/viewtopic.php?t=2422
2018-11-23T23:23:27 < englishman> neat, how do you program it? do you have a stlink?
2018-11-23T23:24:01 < englishman> ah you force it to uart bootloader?
2018-11-23T23:24:58 < englishman> there's a blink program on that page did you try that?
2018-11-23T23:25:18 < mads-> englishman: I can do blink program. I have a st-link. And then blink program works just fine
2018-11-23T23:25:28 < englishman> well, that's something
2018-11-23T23:25:34 < mads-> But I am a little unsure about the bootloader. Do I need one? What does it do? 
2018-11-23T23:25:53 < englishman> all stm32 have a ROM bootloader built in, you can read AN2606 to learn about each one's capabilities
2018-11-23T23:26:40 < mads-> Roger. But I was looking for something I could follow. Because I have tried nearly all programs and all pins on the black pill board. I just can't get my ws2812b's to work
2018-11-23T23:26:41 < englishman> they have this so you can program them over uart, spi, can, etc. without needing a debugger. most modern chips also support USB DFU, some of them even without having an oscillator

2018-11-23T23:27:28 < englishman> did you copypaste a program from somewhere?
2018-11-23T23:28:11 < mads-> Yeah. From nearly anywhere. Also there is an example with the fastled librabry
2018-11-23T23:28:16 < mads-> Which is what most examples are using
2018-11-23T23:29:34 < mads-> I am like SUPER new to this
2018-11-23T23:30:03 < englishman> without seeing any actual code
2018-11-23T23:30:04 < englishman> https://github.com/FastLED/FastLED/wiki/Overview
2018-11-23T23:30:07 < englishman> i dont see any stm32 in here
2018-11-23T23:30:16 < englishman> under "Supported Platforms"
2018-11-23T23:31:24 < englishman> im not sure how someone would get started under stm32+arduino
2018-11-23T23:31:33 < mads-> I am using this version https://github.com/13rac1/FastLED-STM32
2018-11-23T23:31:39 < englishman> it sounds like it could be very easy and very hard at the same time
2018-11-23T23:31:44 < englishman> as you are kind of stumbling around in the dark
2018-11-23T23:31:54 < mads-> And most people and videos I  have seen has been with arduino. I'm am stumbling like crazy
2018-11-23T23:33:02 < englishman> have you tried any of those examples
2018-11-23T23:33:12 < catphish> it's always fun seeing how fast you can drive neopixels with a given MCU
2018-11-23T23:33:13 < englishman> https://github.com/13rac1/FastLED-STM32/blob/stm32f103/examples/RGBSetDemo/RGBSetDemo.ino
2018-11-23T23:34:22 < mads-> englishman: I have tried the FirstLight example. Does not work. 
2018-11-23T23:34:36 < mads-> Even though I am not sure which pin is "pin 3". 
2018-11-23T23:34:43 < mads-> I just tried them all
2018-11-23T23:37:06 < englishman> ^
2018-11-23T23:37:49 < mads-> Cracki: Yeah, I have a multimeter. And some wiggled. But didn't show light when attached to the ws2812b
2018-11-23T23:38:22 < mads-> Cracki: Yeah. Wiggling between 0.2 and 0.5
2018-11-23T23:39:19 < mads-> how so? 
2018-11-23T23:40:30 < mads-> Roger. I will try that out. Thanks
2018-11-23T23:40:38 < catphish> this is driving me mad, i can't figure out how to lay out a high current H bridge with surface mount
2018-11-23T23:40:45 < mads-> My biggest worry is that the ws2812b could be broken.. 
2018-11-23T23:40:54 < catphish> an H bridge includes an inevitable cross
2018-11-23T23:42:04 < mads-> Cracki: I will try it out
2018-11-23T23:42:08 < catphish> Cracki: it's true, in the past i've used through hole mosfets, but with SMD i'm not so sure how to do it
2018-11-23T23:42:40 < catphish> it's possible i'm just overthinking and with the right vias it'll work fine

2018-11-24T00:16:01 < karlp> heh, had a look at getting batteries in holland.  still ~12€ for singles.
2018-11-24T00:16:10 < karlp> not feeling quite as ripped off as before
2018-11-24T00:19:07 < jadew> what batteries are those?
2018-11-24T00:19:51 < karlp> 18650s
2018-11-24T00:20:35 < jadew> ~ $5 in here
2018-11-24T00:20:47 < jadew> Samsung
2018-11-24T00:20:54 < karlp> I'm not going to romania next week, so that's ~ irrelevant :)
2018-11-24T00:21:09 < jadew> no, big online shop
2018-11-24T00:21:43 < jadew> it's basically corner store for me tho, because they have a location a subway station away
2018-11-24T00:23:24 < jadew> karlp, if you need more than a couple, it would make sense to buy them from another country
2018-11-24T00:25:48 < jadew> tme has them too, similarly priced
2018-11-24T00:38:40 < jadew> I went to a machine shop today and asked the workers there if they can make a part for me, from steel (had to be done on a lathe)
2018-11-24T00:39:14 < jadew> asked me how many (I only needed 2) and then they said to come for them monday
2018-11-24T00:39:20 < jadew> and that it wouldn't cost anything...
2018-11-24T00:39:21 < Steffanx> https://www.nkon.nl/rechargeable/18650-size.html not even close to 12 euro, karlp 
2018-11-24T00:40:43 < jadew> they really didn't seem interested in getting anything from me, so I'm not sure what to do next
2018-11-24T00:40:56 < jadew> should I go there with beer or what?
2018-11-24T00:41:03 < Steffanx> Yeah
2018-11-24T00:41:42 < jadew> I hope they like beer
2018-11-24T00:42:07 < jadew> btw, this was the kind of place that makes shit for trains and airplanes
2018-11-24T00:43:49 < jadew> there are a couple of machine shops like that around me
2018-11-24T00:43:57 < jadew> old technology, but still pretty cool

2018-11-24T00:47:35 < jadew> Cracki, yeah, very simple and small
2018-11-24T00:48:11 < jadew> it looks almost like a nail
2018-11-24T00:48:25 < jadew> still, something I couldn't have done myself, as I don't have a lathe
2018-11-24T00:48:57 < jadew> I asked if they can also mill things and they said the mills are always busy

2018-11-24T00:50:29 < jadew> they have CNCs too
2018-11-24T00:50:36 < jadew> huge ones
2018-11-24T00:54:04 < jadew> next stop was a window maker, for $1 he gave me maybe 7 or 8 pcs of the thing I wanted
2018-11-24T00:54:19 < jadew> I needed a 10cm x 6.5 cm glass
2018-11-24T00:54:26 < jadew> that was nice too
2018-11-24T00:54:45 < jadew> (he made them right there)
2018-11-24T00:56:04 < jadew> tomorrow I'll print the box and make the circuitry
2018-11-24T00:56:54 < jadew> hmm, maybe I should have used plexi glass
2018-11-24T00:57:46 < jadew> yeah, but it's more transparent to UV than glass
2018-11-24T00:58:16 < jadew> although, I bet the LEDs I have don't emit too much of the UV glass is opaque to
2018-11-24T01:00:21 < jadew> that's good
2018-11-24T01:02:12 < jadew> now I wonder how glass is made
2018-11-24T01:02:18 < jadew> this is a fantastic material
2018-11-24T01:02:54 < jadew> heh
2018-11-24T01:04:36 < jadew> maybe it got really hot in there?
2018-11-24T01:04:54 < jadew> I think test tubes are made from borosilicate glass
2018-11-24T01:05:15 < jadew> (I have a couple and the type of glass they're made of sounds similar, if it's not the same)
2018-11-24T01:05:55 < jadew> yeah
2018-11-24T01:08:19 < jadew> found out how they make glass that flat
2018-11-24T01:08:31 < jadew> they pour it on top of molten tin
2018-11-24T01:09:12 < jadew> the molten glass stays on top and if the whole thing is not disturbed, it comes out perfectly flat

2018-11-24T12:55:55 < jpa-> https://blockexplorer.com/address/19kXyFbvetft819v4QV5g9vzrjwNqRtvgA   we can see that you haven't paid yet; i'm eagerly waiting to see the video
2018-11-24T12:56:07 < Hamilton> jpa-, But that would generate x86_64 assembly not Arm ISA
2018-11-24T12:56:40 < jadew> jpa-, hmm, can those wallets be created on the fly?
2018-11-24T12:56:48 < jadew> like... could he create 10 000 wallets?
2018-11-24T12:56:51 < jpa-> jadew: yeah, just generate private/public key pair
2018-11-24T12:57:09 < jpa-> Hamilton: sure, but most of your bugs will be in the C/C++ code and will work mostly same on x86_64
2018-11-24T12:57:54 < jpa-> though if you do low-level assembler work, then i can see the need for a simulator and qemu should work
2018-11-24T12:58:18 < Hamilton> jpa-, I actually want to code up something in assembly...
2018-11-24T12:58:37 < Hamilton> On a side note, is it worth to do assembly in this age?
2018-11-24T12:59:33 < jpa-> it can be
2018-11-24T13:00:11 < jpa-> but not for general programming, only for some high-performance algorithms; and I usually just use inline asm & intrinsics for that also
2018-11-24T13:00:26 < jpa-> no need to bother manually about register allocation etc.
2018-11-24T13:00:45 < Hamilton> jpa-, yeah for algorithms...For example FFT or signal processing routines
2018-11-24T13:02:08 < jpa-> https://github.com/ARM-software/CMSIS/tree/master/CMSIS/DSP_Lib/Source   often you can find readymade ones here
2018-11-24T13:02:28 < Hamilton> Is it also possible to write a library in C for Arm-cortex devices, but the actual implementation be assembly? 
2018-11-24T13:02:49 < jpa-> sure, just use inline assembler
2018-11-24T13:10:20 < catphish> morning
2018-11-24T13:12:20 < Hamilton> Does qemu support Cortex-M0 and +? What does *board support* have to do anything with processor support?
2018-11-24T13:12:23 < Hamilton> https://wiki.qemu.org/Documentation/Platforms/ARM
2018-11-24T13:23:34 < catphish> does qemu support any useful arm devices?
2018-11-24T13:23:52 < catphish> like any kind of IO?
2018-11-24T13:24:07 < Hamilton> catphish, I guess it's about processor simulation
2018-11-24T13:24:08 < jpa-> very limited
2018-11-24T13:24:38 < Hamilton> but still, I don't get why they list "board" support in that page instead of processor support
2018-11-24T13:24:41 < jpa-> nah, qemu tries to support more and that's why cpu & board are tied together in its configuration, but it doesn't have any particularly relevant cortex-M boards defined
2018-11-24T13:24:54 < catphish> i was wondering once about writing a hobby ARM OS, but couldn't find a way to simulate anything with IO
2018-11-24T13:25:16 < catphish> ideally i'd like it to simulate a phone/tablet
2018-11-24T13:25:33 < catphish> (with a touchecreen)
2018-11-24T13:25:48 < Hamilton> jpa-, suppose I want to write a FFA for Cortex-M0...Why should it matter that the board is an nRF51822 or SAMD or anything?
2018-11-24T13:25:50 < jpa-> catphish: well that it does do, qemu does simulate raspberry pi and some old phones
2018-11-24T13:26:04 < catphish> jpa-: interesting, i didn't think it did
2018-11-24T13:26:20 < jpa-> Hamilton: because that's how qemu is built; most people using it want more than just the plain cpu
2018-11-24T13:26:20 < catphish> maybe i'll have another look then
2018-11-24T13:26:39 < jpa-> Hamilton: if you use only the cpu, it shouldn't matter to you that there are some extra peripherals hanging around in the simulation
2018-11-24T13:26:46 < catphish> qemu seems to be more of a peripheral emulator than a cpu emulator these days
2018-11-24T13:27:07 < catphish> especially when most people probably use it on x86 with hardware cpu virtualization
2018-11-24T13:27:14 < jpa-> it's both, and has always been; because there is quite limited use to only cpu emulation
2018-11-24T13:27:17 < dongs> sup
2018-11-24T13:27:25 < dongs> i think zyp used  qemu to sim some stm32 stuff
2018-11-24T13:27:39 < Hamilton> jpa-, So does it support M0 core? or AVR?
2018-11-24T13:27:51 < dongs> jadew: ive been getting that spam for months now
2018-11-24T13:27:58 < jpa-> Hamilton: probably not avr, there are other simulators for that
2018-11-24T13:28:05 < dongs> it does do M3 at least
2018-11-24T13:28:06 < jpa-> Hamilton: M0 is a subset of M3 so it should work
2018-11-24T13:28:52 < Hamilton> So am I being an idiot thinking my FFT implementation would be better than GCC's C?
2018-11-24T13:29:12 < jpa-> Hamilton: also look at the section about "-M virt" if you want to run without peripherals

2018-11-24T13:29:56 < jpa-> Hamilton: no, it is easy to beat GCC's C, especially on Cortex-M4 and others with DSP instructions; but you may be an idiot if you think you can beat ARM's preoptimized algorithms by much
2018-11-24T13:30:20 < jpa-> but of course your situation may be different than the generic algorithm assumes
2018-11-24T13:30:54 -!- BrainDamage [~BrainDama@unaffiliated/braindamage] has joined ##stm32
2018-11-24T13:31:13 < Hamilton> jpa-, and by Arm's preoptimized algorithms use mean the link you mentioned about CMSIS?
2018-11-24T13:31:19 < jpa-> yeah, dsplib
2018-11-24T13:32:43 < Hamilton> yeah I guess I'd be an idiot in that case...can't beat corporate smarties with time/manpower
2018-11-24T13:32:45 < jpa-> note also that while qemu does simulate the functionality quite accurately, it does not simulate timing; stuff like RAM access times or instruction cycle counts are not accurate in the simulation
2018-11-24T13:33:00 < jpa-> so you can't use simulation to accurately rate performance
2018-11-24T13:34:45 < catphish> looks like qemu can simulate some 32 bit arm devices, like nokia n800
2018-11-24T13:34:47 < Hamilton> Isn't time taken for each instruction set routine fixed and predetermined? I guess it only is dependent on clock or other variables but at least the relation is linear 
2018-11-24T13:34:53 < catphish> not sure about 64 bit, the list isn't clear
2018-11-24T13:34:59 < jpa-> Hamilton: no, it isn't fixed
2018-11-24T13:35:45 < jpa-> i'd give a link but infocenter.arm.com is down :P
2018-11-24T13:36:30 < Hamilton> catphish, If you like smartphones, look into postmarketOS (which also has a channel here)..it's based on Alpine linux (with musl instead of glibc) so you can have a Alpine machine and a postmarketOS phone and pretty much they'd behave the same
2018-11-24T13:37:07 < jpa-> http://webcache.googleusercontent.com/search?q=cache:Bt2EJuqxhFoJ:infocenter.arm.com/help/topic/com.arm.doc.ddi0432c/CHDCICDF.html&hl=fi&gl=fi&strip=1&vwsrc=0   ah, for cortex-m0 it looks to be quite fixed because it has no divide or other more advanced instructions; but different instructions still take different amount of time and qemu doesn't account for that
2018-11-24T13:37:33 < jpa-> for Cortex-M3 and higher, even the same instruction can vary in timing
2018-11-24T13:38:04 < catphish> Hamilton: interesting, i want low level though
2018-11-24T13:38:27 < Hamilton> I didn't really know that...:(...but correct-ness is also good if I could set up qemu

2018-11-24T14:43:40 < Thorn> Reviewing the twentieth century, it is hard to escape the conclusion that two themes have dominated Germany’s history. On the one hand there is the pursuit of economic and technological progress, which for much of the century made Germany, along with the United States and latterly Japan, China and India, one of the largest economies in the world. On the other hand there is the pursuit of warfare on a hitherto unimagined scale.

2018-11-25T03:11:18 < kakimir> and if you go all way up eventually there is negative zero kelvin
2018-11-25T03:11:39 < BrainDamage> which means electrons' rest position is an energized state instead of ground state

2018-11-25T14:38:13 < Steffanx> its mainly that because they keep backups of the databases in the download
2018-11-25T14:38:18 < dongs> no
2018-11-25T14:38:21 < Steffanx> not?
2018-11-25T14:38:24 < Steffanx> oh that is cube mx
2018-11-25T14:38:29 < dongs> the new F7 trash is literally 1.2gb for the update
2018-11-25T14:38:33 < dongs> i donno how big the previous one was
2018-11-25T14:38:40 < dongs> ill check, its still unzipping
2018-11-25T14:39:06 < Steffanx> st website is so fast nowadays
2018-11-25T14:40:03 < zyp> oh, stm32g0 is even listed on mouser
2018-11-25T14:40:26 < zyp> apparently it's M0+, so maybe it's just F0 with a better core
2018-11-25T14:41:02 < Steffanx> or L0?
2018-11-25T14:41:52 < Steffanx> Which is also pretty close to F0 with just a better core 
2018-11-25T14:42:10 < zyp> L0 is slower

2018-11-25T14:50:16 < Steffanx> ntfreak was our guy with inside ST info. Tell us about G0? :D
2018-11-25T14:50:22 < dongs> PD peripheral is called UCPD
2018-11-25T14:50:44 < dongs> L5 also has it apparently
2018-11-25T14:52:53 < dongs> By getting more from technology to get more from life, ST stands for life.augmented.
2018-11-25T14:52:58 < dongs> what the shit does that even mean
2018-11-25T14:53:38 < Steffanx> So the F7 stuff is so huge because it has huge binaries and images (touchgfx and stemwin) in it.
2018-11-25T14:53:46 < dongs> no uguufx?
2018-11-25T14:54:18 < Steffanx> Nah, why would they. it had to be STuguufx then.
2018-11-25T14:59:57 < dongs> in that case, it'd be more like stfuguufx

2018-11-25T15:18:45 < PeterM> so i gotta parallel up some high current contacts on a connector, should i do the normal thing and put the paralleld contacts adjacent to each other on the connector, or jsut split it into a mirror image
2018-11-25T15:18:47 < dongs> lmao thats a terrible X
2018-11-25T15:19:42 < PeterM> then end user doesnt need to use their brain and think about connector orientation
2018-11-25T15:19:43 < dongs> i'd be very shocked if uguufx actually supported kerning like this
2018-11-25T15:20:52 < karlp> Steffanx: just looked at prices briefly on line, I didnt' see any any cheaper than 11€?
2018-11-25T15:21:17 < Steffanx> https://www.nkon.nl/rechargeable/18650-size.html  i do, unless you need something very fancy.
2018-11-25T15:21:32 < karlp> that's more like it.
2018-11-25T15:21:38 < karlp> now, can I walk in somewhere and getthem?
2018-11-25T15:21:46 < karlp> I'm only in country for 48hours.
2018-11-25T15:21:50 < Steffanx> that might be some issue

2018-11-25T15:22:37 < karlp> I'm still going to pay 11@ or somethign at a vape shop in amsterdam, it's sitll half the price of locally.

2018-11-25T17:53:09 < Steffanx> just to get rid of the shit
2018-11-25T17:53:20 < kakimir> I have collected.

2018-11-25T17:54:03 < bitmask> no I meant Steffanx 
2018-11-25T17:54:20 < kakimir> I mean I have collected some broken electronics that was not even originally mine
2018-11-25T17:54:31 < Steffanx> bitmask here in dutchland you pay for it yes.
2018-11-25T17:54:41 < kakimir> also some really cheap shit that has been trash right out of factory
2018-11-25T17:54:42 < zyp> pay for what?
2018-11-25T17:54:50 < bitmask> for what though, garbage collectors to pick up big items? or what

2018-11-25T17:55:49 < Steffanx> if i have to get rid of big things i have to take it to some place that takes it. Which i have to pay for :P

2018-11-25T17:56:04 < Steffanx> some place = recycler.
2018-11-25T17:56:24 < kakimir> they receive electronics for free
2018-11-25T17:56:31 < bitmask> regular trash is covered by house taxes I believe but we have a recycling place in town to drop off electronics, paper, plastic, whatever
2018-11-25T17:56:36 < zyp> same here
2018-11-25T17:56:37 < kakimir> but things like refrigerators etc. you need to pay some 10eur or so
2018-11-25T17:56:43 < kakimir> sofas
2018-11-25T17:56:44 < bitmask> and they pick up large items every other week I think
2018-11-25T17:56:54 < zyp> electronics are free, also some other items are
2018-11-25T17:57:13 < kakimir> I think it's free when materials are valuable
2018-11-25T17:57:16 < zyp> and for the stuff you actually have to pay for, there's some yearly allowance
2018-11-25T17:57:20 < zyp> that's not it
2018-11-25T17:57:24 < Steffanx> here no you longer pay by taxes, you pay by how often you have the bin emptied.

2018-11-25T17:57:52 < zyp> on shit like fridges and stuff here, you're paying an environment tax when you buy it, which covers handling it when it's thrown away

2018-11-25T22:50:41 < BrainDamage> it's a very popular brand of pasta, as far as sauces go, it's okay
2018-11-25T22:52:05 < BrainDamage> add a ladle of starchy water from pasta, and toss it in a frying pan with the pasta alongside a teaspoon of olive oil to improve the flavour
2018-11-25T22:52:16 < BrainDamage> on high heat
2018-11-25T22:53:25 < Steffanx> What pasta will it be crt ?
2018-11-25T22:54:31 < Steffanx> yikes, the most awful ones
2018-11-25T22:55:01 < Steffanx> Will you stop pumping?
2018-11-25T22:55:56 < Steffanx> no "real" spaghetti?
2018-11-25T22:56:09 < BrainDamage> spaghetti are overrated
2018-11-25T22:56:27 < BrainDamage> linguine and bavette are pretty decent replacements if not better
2018-11-25T22:56:59 < Steffanx> to me its all the same :P
2018-11-25T22:57:06 < Steffanx> as in pasta => meh
2018-11-25T22:59:01 < englishman> store bought pasta is pretty meh
2018-11-25T22:59:11 < Steffanx> doing it yourself is even more meh
2018-11-25T22:59:17 < englishman> fresh rolled pasta is gr8
2018-11-25T22:59:29 < englishman> lemon basil
2018-11-25T23:00:02 < englishman> dried tomato and rosemary
2018-11-25T23:00:41 < BrainDamage> roasted spinach, avocado, lemon rind, heavy cream and a spruce of dill
2018-11-25T23:00:52 < BrainDamage> and coriander
2018-11-25T23:01:00 < BrainDamage> blend it
2018-11-25T23:02:50 < Steffanx> and thats just a tiny part of the entire dish :P
2018-11-25T23:03:35 < BrainDamage> except roasting the spinach, it takes like 30s
2018-11-25T23:04:02 < karlp> qyx: sure: https://www.etactica.com/products/eg-200/ :)
2018-11-25T23:04:19 < BrainDamage> or roasted garlic with roasted bell pepper and roasted fresh halapeno chily all coated in oil, collect the oil and the vegetables, blend with a HEAVY amount of black pepper and salt and ricotta, add water to adjust consistency
2018-11-25T23:04:36 < BrainDamage> and add a dash of hot paprika
2018-11-25T23:05:02 < BrainDamage> this one is more complex so you might want to make quite a bit and save
2018-11-25T23:05:24 < Steffanx> can i skip the garlic?
2018-11-25T23:05:34 < BrainDamage> sure
2018-11-25T23:06:19 < BrainDamage> caramelized onions or scallions would fit well too

2018-11-25T23:20:20 < jadew> friend of mine found a job in Itally, and when he came back he told me what he had to do
2018-11-25T23:20:54 < jadew> his job was to drill holes into cherry trees (about 7-8 cm in diameter)
2018-11-25T23:20:59 < jadew> and stuff them with chemicals
2018-11-25T23:21:35 < jadew> they skipped going through the roots altogether

2018-11-25T23:24:06 < jadew> I don't think in the US you have a right not to be offended, like in the UK
2018-11-25T23:25:28 < jadew> I'm about to try dry film photoresist but I don't have the developer
2018-11-25T23:26:52 < jadew> sodium carbonate or percarbonate - what kind of washing products am I looking for?
2018-11-25T23:27:05 < jadew> do regular detergents have it?
2018-11-25T23:27:52 < BrainDamage> sodium percarbonate, oxyclean
2018-11-25T23:29:24 < BrainDamage> you can also heat sodium bicarbonate to convert it to sodium carbonate
2018-11-25T23:29:38 < BrainDamage> it releases water and co2
2018-11-25T23:29:55 < jadew> interesting, I'll keep that as an option
2018-11-25T23:30:39 < jadew> we don't have oxyclean
2018-11-25T23:33:37 < jadew> the detergents I have don't mention it
2018-11-25T23:34:45 < jadew> hold on
2018-11-25T23:34:52 < jadew> is sodium carbonate good to eat?
2018-11-25T23:37:17 < Thorn> https://www.youtube.com/watch?v=ZWhjDBmlcqg mars insight landing soon
2018-11-25T23:41:08 < jadew> I mean, if you can use baking soda to make detergent... does that mean that cooked foods that use baking soda contain detergent?
2018-11-25T23:41:43 < jadew> and with that, I now want to eat some mici, since they're made with baking soda and they're fucking delicious
2018-11-25T23:45:03 < BrainDamage> baking soda is sodium bicarbonate, not sodium carbonate
2018-11-25T23:45:21 < jadew> yeah, but you said that if you heat it up it turns into sodium carbonate
2018-11-25T23:45:40 < BrainDamage> cooked foods the sodium bicarbonate reacts with the rest of the food
2018-11-25T23:46:01 < BrainDamage> a + b + heat is not a+heat and b+heat
2018-11-25T23:46:42 < BrainDamage> also, detergent doesn't necessarily mean inedible
2018-11-25T23:46:51 < BrainDamage> eg acetic acid is a detergent, and you can eat it
2018-11-25T23:47:01 < BrainDamage> just not in high concentrations
2018-11-25T23:47:19 < BrainDamage> hell, pretzels are prepared using caustic soda
2018-11-25T23:47:29 < jadew> lol, really?
2018-11-25T23:48:35 < jadew> I'm reading that sodium peroxyhydrate is also good as a developer
2018-11-25T23:49:07 < jadew> and I've read that word on one of the detergent boxes
2018-11-25T23:49:36 < jadew> I'll give it a try

2018-11-26T00:30:14 < jadew> yeah, I don't think this is war tho
2018-11-26T00:30:19 < jadew> nor do I think it will escallate
2018-11-26T00:30:43 < jadew> it would be foolish for Ukraine to declare war on Russia for such a small event
2018-11-26T00:31:08 < Steffanx> Arent ukrain and russia in semi-war?
2018-11-26T00:31:09 < jadew> it's clear the Russians don't want war, because if they did, they would have done something worse
2018-11-26T00:31:20 < jadew> yeah... so this behaviour is understandable

2018-11-26T00:56:42 < jadew> not sure when we started with english...
2018-11-26T00:56:59 < jadew> but I didn't learn anything in school
2018-11-26T00:57:26 < jadew> french didn't stick and I don't remember learning anything useful in english
2018-11-26T00:57:38 < jadew> wasted years
2018-11-26T00:58:57 < jadew> history didn't work for me either (I'd like to have the time to study it now, because I find it mildly fascinating, but back then I didn't give a crap about it)
2018-11-26T00:59:42 < jadew> didn't care for literature either... why would they force us to learn all this shit we don't like?

2018-11-26T01:55:05 < jadew> but yeah, I think they're doing the best they can to conceal that the ratings are faked
2018-11-26T01:55:16 < jadew> they first removed the comments section
2018-11-26T01:56:52 < jadew> in the past there used to be the random movie that had good ratings despite being shit, but it was because a large percentage of the viewers actually enjoyed it
2018-11-26T01:58:43 < jadew> but in the past couple of years you had crappy movies, where you even got the vibe from the comments section that people didn't like it, and they still had over the top ratings
2018-11-26T01:59:03 < jadew> you can still see that now with the user reviews

2018-11-26T11:33:58 < zygron_> i have a weird problem, we're about to make a new batch of a board that has an STM32F4, when testing the RTC clock precision on the first board we mounted it turns out the oscillator is 6.5% off (there's a register you can set to toggle a pin at the RTC clock frequency /64), i get 478Hz instead of the expected 512Hz (the RTC would be running at 30.592Khz instead of 32.768Khz), i made sure the 
2018-11-26T11:33:59 < zygron_> quartz load capacitors are ok, i replaced the quartz with an indentical one (same SMD part), same thing occurs, but it works with a different 32.768Khz quartz (non SMD)... boards from the previous batch don't exhibit the problem (the PCB is identical, there has been no revision), any idea what the problem could be?
2018-11-26T11:34:06 -!- zygron_ is now known as mitrax
2018-11-26T11:37:59 < mitrax> i don't get it, even if the load capacitors were incorrect or if there were a parasitic capacitance cause by solder flux residue or whatever it wouldn't be so much far off, would it?

2018-11-26T12:19:05 < mitrax> i did, i desoldered the xtal on the new board that doesn't work properly, and mounted it on an old board, it works
2018-11-26T12:21:11 < mitrax> i also put the xtal of a board that works and put it on the new board, and the problem remains, the frequency is still off
2018-11-26T12:24:21 < qyx> so it seems it is board batch related despite the fact is has the same layout?
2018-11-26T12:24:35 < PeterM> is the board manufacturer the same?
2018-11-26T12:25:38 < PeterM> maybe the manufacturer is using a different substrate, or a substrate with terrible dielectric properties
2018-11-26T12:30:39 < mitrax> same manufacturer yeah, but could a pcb problem cause the oscillator to be that much off? i thought it wouldn't start in such case
2018-11-26T12:33:01 < PeterM> there are a lot of unpredictable effects
2018-11-26T12:34:00 < PeterM> the actual xtal my be cut slightly unsymmertrical, and the extra capacitance makes it start up in a different resonant mode
2018-11-26T12:34:06 < PeterM> who knows
2018-11-26T12:35:03 < mitrax> i just tried with a different SMD quartz model, same problem, weird, i guess it's either PCB or MCU related
2018-11-26T12:37:16 < PeterM> i cant remember if the stm32 have it but some mcus have the option of setting different xtal drive levels
2018-11-26T12:37:25 < PeterM> have you tried playing with that?
2018-11-26T12:37:43 < mitrax> no let me check
2018-11-26T12:40:53 < PeterM> you probably already have this open https://www.st.com/content/ccc/resource/technical/document/application_note/c6/eb/5e/11/e3/69/43/eb/CD00221665.pdf/files/CD00221665.pdf/jcr:content/translations/en.CD00221665.pdf but if you dont there is the 10ft long link

2018-11-26T12:48:28 < zyp> the whole thing is kinda dumb, would be more useful if tools just looked at iManufacturer and iProduct
2018-11-26T12:49:19 < karlp> sure, but cant fix that now, and I'm sure this came about because they didn't all include those strings
2018-11-26T12:49:35 < karlp> ie, for instance, allwinner FEL mode.
2018-11-26T12:49:41 < karlp> it has no strings provided,

2018-11-26T15:25:37 < jadew> haha, true
2018-11-26T15:25:44 < jadew> it usually works
2018-11-26T15:26:01 < dongs> inverted = is that for some fucking homebrew pcb trash
2018-11-26T15:26:15 < jadew> dongs, that's your homebrew pcb trash btw
2018-11-26T15:26:27 < jpa-> yeah, with negative photoresist for some reason
2018-11-26T15:26:32 < jadew> I'm trying to do dry film transfer
2018-11-26T15:26:33 < jpa-> seems like waste of toner
2018-11-26T15:26:41 < dongs> what does kikecad output, pdf? altium DISASTER has a checkbox at gerber output
2018-11-26T15:26:44 < dongs> [x] INVERT
2018-11-26T15:26:46 < dongs> pretty fucking pro
2018-11-26T15:27:02 < dongs> maybe one day kikecad will get feature parity with altium summer 2003 edition
2018-11-26T15:27:06 < dongs> mabbe in 2023
2018-11-26T15:27:16 < Haohmaru> aww
2018-11-26T15:27:21 < jpa-> kicad has that checkbox in pdf output, not in gerber output and not in print dialog :P
2018-11-26T15:27:32 < dongs> so why cant you just print pdf
2018-11-26T15:27:39 < dongs> acrobad has 1:1 print option
2018-11-26T15:27:40 < jadew> jpa-, yeah, and it doesn't respect the board edges with inverted output...
2018-11-26T15:27:54 < jadew> dongs, because it doesn't respect the board edges
2018-11-26T15:28:03 < dongs> what does that mean
2018-11-26T15:28:15 < jadew> the black goes beyond the boards edges
2018-11-26T15:28:16 < jpa-> i guess it makes his whole background black instead of just the board area
2018-11-26T15:28:21 < jadew> yeah

2018-11-26T15:28:30 < jadew> I have to plot to SVG, correct in inkscape and then print...
2018-11-26T15:28:42 < jadew> but then inkscape won't print... gives me a blank page
2018-11-26T15:29:24 < jadew> expensive PCB and I may have to make several to get the impedance right
2018-11-26T15:29:26 < jpa-> export to pdf from inkscape?
2018-11-26T15:29:27 < dongs> i ordered my YMU breakout like friday
2018-11-26T15:29:32 < dongs> its already done
2018-11-26T15:29:33 < dongs> wiht stencil
2018-11-26T15:29:42 < jadew> so I'm hoping to go through several boards today
2018-11-26T15:29:50 < dongs> not if you cant get this shit working
2018-11-26T15:30:03 < jadew> jpa-, I'll give that a try, but I found a bug report where neither printing nor exporting to PDF works :)
2018-11-26T15:30:46 < jadew> dongs, yeah...
2018-11-26T15:31:19 < Haohmaru> this is why i don't mention that i use kicad in here
2018-11-26T15:31:39 < dongs> beacuse we'd laugh at you for wasting time?
2018-11-26T15:32:05 < Haohmaru> you'd laugh at anything
2018-11-26T15:32:18 < dongs> i'd probly laugh at your stories of failing with altium
2018-11-26T15:32:25 < dongs> "but it doesnt work like kikecad!!!!"
2018-11-26T15:33:26 < Haohmaru> as we can see, you'd even laugh at hypothetical things, which never happened
2018-11-26T15:33:26 < jadew> if altium was $500, I'd get it
2018-11-26T15:33:35 < dongs> its $100 if youre a poor jew student
2018-11-26T15:33:51 < jadew> I'm not...
2018-11-26T15:34:00 < dongs> well, go enroll in some community college
2018-11-26T15:34:04 < Haohmaru> im poor, but i'm not a jew, nor a student ;P~
2018-11-26T15:34:04 < dongs> still cheaper than $500
2018-11-26T15:34:12 < Haohmaru> and 100 bucks is not cheap
2018-11-26T15:34:19 < dongs> fuck outta here
2018-11-26T15:34:22 < dongs> win10pro license is $99
2018-11-26T15:34:24 < jadew> actually, that's really cheap
2018-11-26T15:34:37 < dongs> yeah for what you get its a fuckign steal
2018-11-26T15:34:50 < dongs> Ocrad with similar features to altium costs like $20k
2018-11-26T15:35:16 < Haohmaru> okay, but still, it won't be 100 bucks for me
2018-11-26T15:35:17 < dongs> and its gui is straight out of 1989
2018-11-26T15:37:17 < karlp> does the $100 license actually allow you to make commercial designs?
2018-11-26T15:37:23 < dongs> no of course not
2018-11-26T15:37:26 < Haohmaru> o_O
2018-11-26T15:37:29 < Haohmaru> dafuq then
2018-11-26T15:37:29 < karlp> so it's irrelevant then.
2018-11-26T15:37:31 < dongs> doens't stop aandrew from doing it tho
2018-11-26T15:37:35 < dongs> :)
2018-11-26T15:37:43 < dongs> more like aandJEW
2018-11-26T15:37:44 < Haohmaru> oh, just don't tell teh copz
2018-11-26T15:38:28 < Haohmaru> btw, i don't want win10 even if it's for free
2018-11-26T15:38:47 < jadew> who needs a stable OS, right?
2018-11-26T15:38:56 < dongs> yeah

2018-11-26T15:53:24 < Haohmaru> btw, the svg output ain't exactly the same as teh gerb0rz
2018-11-26T15:53:58 < karlp> what are you trying to do with the printout?
2018-11-26T15:54:11 < Haohmaru> there wuz some diffs, i don't remember the details
2018-11-26T15:54:36 < jadew> karlp, expose a UV sensitive board
2018-11-26T15:54:52 < karlp> ok then.

2018-11-26T15:57:37 < HelloWorld> Hi everyone. I have a question about ROM memory.
2018-11-26T15:57:49 < HelloWorld> Say that I store some data in the ROM memory and then turn the device off
2018-11-26T15:57:59 < HelloWorld> Will the data still be available when the device is powered ON again?
2018-11-26T15:58:17 < Haohmaru> wut iz a ROM memory eggzactly?
2018-11-26T15:58:19 < zyp> what do you mean by "ROM memory"?
2018-11-26T15:58:28 < HelloWorld> Ehm, like the memory where the programm is stored
2018-11-26T15:58:32 < HelloWorld> That's ROM right?
2018-11-26T15:58:38 < Haohmaru> isn't it flash?
2018-11-26T15:58:42 < HelloWorld> Ah yeah, that
2018-11-26T15:58:56 < zyp> flash is a type of ROM, ROM is pretty general term
2018-11-26T15:59:02 < Haohmaru> well then, if it has been written, then it's gonna stay there
2018-11-26T15:59:33 < HelloWorld> Okay great. Then second question. Do compilers generally use the first part of the flash memory first?
2018-11-26T15:59:52 < HelloWorld> I want to store some GPS data at the end so I can speed up the cold start, but preferably without overwriting the program
2018-11-26T16:00:04 < zyp> it's not decided by the compiler, it's decided by the linker
2018-11-26T16:00:16 < zyp> and generally the answer is yes
2018-11-26T16:00:24 < Haohmaru> __flash maybe?
2018-11-26T16:01:01 < HelloWorld> Great, thank you very much
2018-11-26T16:01:03 < HelloWorld> Have a nice day guys!

2018-11-26T17:40:03 < mawk> I wrote 1200 lines of boilerplate so that the lacunar client's code can compile
2018-11-26T17:40:11 < mawk> he didn't give me everything because of IP
2018-11-26T17:40:24 < mawk> so I defined every single missing constant, every single missing struct with all the members
2018-11-26T17:40:34 < mawk> I hope I can add that to the bill

2018-11-26T18:05:22 < kakimir> there apparently is no way to divide 32768 with 2^x numbers to get about 100ms period?

2018-11-26T18:05:56 < mawk> if x isn't an integer you can, of course
2018-11-26T18:06:04 < mawk> just logarithmify all that stuff a little
2018-11-26T18:06:24 < kakimir> I think I'll go for 16ms period

2018-11-26T18:09:15 < kakimir> maybe it won't hurt to run interrupt even faster
2018-11-26T18:09:41 < kakimir> but I would need to do atomic stuff then

2018-11-26T18:10:36 < kakimir> Cracki: can I get such from 32768hz?
2018-11-26T18:11:09 < kakimir> Haohmaru: attiny816 and using rtc periodic interrupt
2018-11-26T18:11:35 < kakimir> Cracki: lemme see
2018-11-26T18:11:49 < Haohmaru> don't you have a prescaler to get 1ms interrupt from it?
2018-11-26T18:12:02 < Haohmaru> then you could use a uint8_t counter to count to 100 ;P~
2018-11-26T18:12:16 < Haohmaru> or.. something
2018-11-26T18:12:17 < kakimir> all scalers are 2**x
2018-11-26T18:12:48 < kakimir> it's in sleep most of the time yes
2018-11-26T18:12:58 < kakimir> I just scoped how much it actually does stuff
2018-11-26T18:13:20 < kakimir> if we ignore 5ms busyloop then about 2-3milliseconds
2018-11-26T18:13:28 < kakimir> in a period that is second
2018-11-26T18:13:32 < kakimir> 1 second
2018-11-26T18:14:39 < kakimir> from moment 1second periodic interrupt enters to moment thing is about to get into sleep
2018-11-26T18:15:00 < kakimir> I just need a faster interrupt to run some led sequencing
2018-11-26T18:15:04 < Haohmaru> ugh, on my xmega, there's a 32divider first, and then the prescaler.. so with 1024 prescaler i get 1sec interrupt
2018-11-26T18:15:35 < kakimir> there is a clock option (2^^15)hz / 32

2018-11-26T19:40:06 < Thorn> afrikaans?
2018-11-26T19:41:04 < mawk> it was dutch Cracki, just a weird accent
2018-11-26T19:41:08 < mawk> yeah maybe afrikaans
2018-11-26T19:41:32 < mawk> but why would an afrikaner show up in my little hipster café in the heart of paris

2018-11-26T19:48:51 < Steffanx> The flemish talk like that
2018-11-26T19:48:54 < mawk> what's flemish ?
2018-11-26T19:48:55 < mawk> ah
2018-11-26T19:48:57 < mawk> vlaams ?
2018-11-26T19:49:00 < Steffanx> Yes
2018-11-26T19:49:09 < mawk> maybe
2018-11-26T19:49:28 < mawk> but I've been in belgium a couple time and don't remember that accent
2018-11-26T19:49:55 < Steffanx> Or perhaps southern dutchland. Its similar in some regions
2018-11-26T19:50:10 < mawk> my dutch book say some dutch city hipsters like in reality tv take a special accent to sound snobbish
2018-11-26T19:53:17 < Steffanx> Idk
2018-11-26T19:53:26 < Steffanx> Fuck reality tv
2018-11-26T19:56:34 < mawk> yeah reality tv or news host or anything
2018-11-26T19:57:00 < mawk> something similar happened a while ago in France, TV smoothed out any regional accent
2018-11-26T19:57:53 < mawk> also people would use some kind of commoner-dialect which is basically ugly invalid french
2018-11-26T19:58:18 < mawk> and after TV appeared everyone progressively started speaking the real french

2018-11-26T22:33:13 < Steffanx> When do you plan to get in?
2018-11-26T22:34:01 < zyp> last estimate was that it would be done around newyears
2018-11-26T22:35:11 < zyp> I've said I don't want to pay it until after newyears due to tax stuff
2018-11-26T22:36:07 < zyp> I save 10k NOK in taxes by paying it next year instead of this year
2018-11-26T22:36:30 < zyp> so formally it'll be mine some time in january
2018-11-26T22:36:49 < Thorn> weirdest door design I've ever seen
2018-11-26T22:36:56 < zyp> my bank guy said we could prepare all the paperwork in december and just formally file it in january
2018-11-26T22:38:30 < Thorn> does fire code allow that stuff between the houses
2018-11-26T22:39:28 < zyp> Thorn, I'm a bit confused about that myself
2018-11-26T22:39:45 < zyp> I mean, I assume the house is built to code and everything
2018-11-26T22:39:58 < Thorn> the gap is pretty small without that balcony thing
2018-11-26T22:40:12 < zyp> but I don't see how fire spread between the units is limited
2018-11-26T22:40:16 < zyp> yeah, it's 3m
2018-11-26T22:41:16 < Thorn> I watched enough russian firefighter videos where they're swearing about a small gap while trying to save a neighbor's house
2018-11-26T22:42:18 < zyp> haha

2018-11-27T01:27:19 < kakimir> pfc was a suspect so we took some old AC/AC adapters and tied them low voltage lines together to form an isolation transformer

2018-11-27T01:30:37 < kakimir> pfc needs some voltage to vsense to activate
2018-11-27T01:30:58 < kakimir> divider ratio was 195 or so

2018-11-27T01:32:51 < kakimir> he doesn't even have limited current supply
2018-11-27T01:33:15 < PeterM> whats he trying to fix a leaf charger for then?
2018-11-27T01:33:29 < kakimir> to get DC charging or so
2018-11-27T01:33:33 < kakimir> fast charging
2018-11-27T01:33:40 < kakimir> throw some custom board in there
2018-11-27T01:33:50 < kakimir> whisper with charging station
2018-11-27T01:34:13 < kakimir> so what happend when he started poking the board with probes
2018-11-27T01:35:04 < kakimir> there is big transistors with those metal back planes in the breeze on the board
2018-11-27T01:36:12 < kakimir> he discharges pfc caps though his hand from board to transistor backplane
2018-11-27T01:36:56 < kakimir> 8 x 170uF @ +300V
2018-11-27T01:38:18 < kakimir> "fuck I think I got burn in my hand" and looks at his hand and puts gloves on and continues probing

2018-11-27T01:41:14 < kakimir> PeterM: if DC voltage is fed to PFC
2018-11-27T01:41:17 < kakimir> what does it do?
2018-11-27T01:41:36 < kakimir> does pfc even care?
2018-11-27T01:42:55 < kakimir> it just allows directly propotional current compared to vsense voltage and doesn't care less about anything else?
2018-11-27T01:43:20 < kakimir> for DC charging it has a contactor though
2018-11-27T01:43:41 < kakimir> directly connects charging port prongs to battery
2018-11-27T01:44:01 < kakimir> bypasses all the power electronics
2018-11-27T01:44:18 < PeterM> depends on the PFC topology, but i assume in the leaf charger it would be bridgeless pfc, in that case it would jsut use one half of the boost converter
2018-11-27T01:44:29 < kakimir> then it just whispers in datalines to give juice
2018-11-27T01:44:53 < PeterM> and it would pull full current because voltage and current would always be in phase
2018-11-27T01:45:19 < kakimir> it has 2 sets of fets
2018-11-27T01:45:33 < kakimir> with diodes at their side
2018-11-27T01:45:38 < kakimir> paraller maybe
2018-11-27T01:45:43 < PeterM> yes, google bridgeless pfc
2018-11-27T01:46:41 < kakimir> only 2 gates are driven
2018-11-27T01:48:14 < con3> hmm..everytime I start up the mcu, the interrupt triggers, no matter what the input
2018-11-27T01:48:40 < kakimir> what interrupt?
2018-11-27T01:48:45 < kakimir> and did you set it up?
2018-11-27T01:49:37 < kakimir> /o/
2018-11-27T01:50:14 < kakimir> maybe first interrupt condition is generated before interrupt is generated
2018-11-27T01:50:24 < kakimir> *enabled
2018-11-27T01:50:40 < con3> got it setup as rising on the gpio pin 3, then activate it with set priority and nvic enable irq, also tried clearing a pending bit but nothing.

2018-11-27T01:58:06 < kakimir> and DC charging
2018-11-27T01:58:12 < con3> only 6.6 kw
2018-11-27T01:58:23 < englishman> better swap the motor then
2018-11-27T01:58:32 < kakimir> why swap motor?
2018-11-27T01:58:38 < englishman> cuz the motor, inverter, charger, and dcdc are all one unit
2018-11-27T01:58:43 < englishman> and final drive
2018-11-27T01:58:49 < kakimir> yes
2018-11-27T01:58:56 < kakimir> he doesn't give a fuck
2018-11-27T01:59:00 < kakimir> he has splitted them
2018-11-27T01:59:01 < englishman> you could maybe add dc tho
2018-11-27T01:59:11 < kakimir> no final drive
2018-11-27T01:59:21 < kakimir> inverter is separated
2018-11-27T01:59:28 < kakimir> charger is separated
2018-11-27T02:00:33 < englishman> looks like final drive bolts on the side
2018-11-27T02:00:49 < kakimir> it is not a problem to bolt it off
2018-11-27T02:01:26 < englishman> n e way
2018-11-27T02:01:33 < englishman> surely you could just swap all the shit in from a wreck
2018-11-27T02:03:24 < kakimir> he got also inverter to swap in
2018-11-27T02:04:35 < kakimir> after he throws his own controller in it with software that limits only to motor maximum current and battery maximum current
2018-11-27T02:05:17 < kakimir> safe bet to get more power
2018-11-27T02:05:44 < kakimir> maximum torque will be the same
2018-11-27T02:05:59 < kakimir> it will just extend to higher motor speeds

2018-11-27T02:08:56 < kakimir> if you clear it
2018-11-27T02:09:00 < kakimir> does it stick?
2018-11-27T02:09:53 < con3> It sticks, trying to figure out when and how its getting triggered
2018-11-27T02:10:25 < kakimir> maybe level trigger is always active?
2018-11-27T02:10:35 < kakimir> do you need to activate it?
2018-11-27T02:10:43 < kakimir> and rule of thumb - always clear first
2018-11-27T02:12:33 < kakimir> unless it desired operation to get interrupt from event before enabling
2018-11-27T02:15:22 < kakimir> should analyze data
2018-11-27T02:15:29 < kakimir> before falling in sleep
2018-11-27T02:17:19 < con3> very confused, I'm writing to a pin (GPIOE-PIN-11) and when doing this the interrupt on GPIOE-PIN-3 gets triggered...their not connected in any way
2018-11-27T02:21:08 < kakimir> interrupt is configured wrong
2018-11-27T02:21:19 < kakimir> you have it in multiple pins instead of one
2018-11-27T02:21:20 < kakimir> ?
2018-11-27T02:22:03 < kakimir> you masked some bit wrong and ended up with multiple pins with edge trigger
2018-11-27T02:22:08 < kakimir> something like that
2018-11-27T02:25:45 < kakimir> used bit position instead of bit mask
2018-11-27T02:33:25 < kakimir> con3: any conclusion?
2018-11-27T02:34:24 < con3> kakimir: Debugging :p sorry got a bit caught up, I'm a little lost why it's not clearing the bit
2018-11-27T02:37:28 < kakimir> is it some per pin bit
2018-11-27T02:37:50 < kakimir> so that you know it's from that pin
2018-11-27T02:38:51 < kakimir> I think it's not 2 seperate bugs to have interrupt from pin you shouldn't get interrupt from and to have pending interrupt when you shouldn't
2018-11-27T02:38:54 < con3> kakimir: Yes, it's EXTI3,it's only set for GPIO_PIN_3 of GPIOE
2018-11-27T02:40:08 < con3> It gets cleared perfectly after the interrupt executes though
2018-11-27T02:40:11  * con3 frowns
2018-11-27T02:43:48 < kakimir> is your device physically solid for sure?
2018-11-27T02:44:12 < kakimir> absolutelly no connection between those pins?
2018-11-27T02:44:34 < kakimir> no tools or measurements on those pins that could cause it
2018-11-27T02:44:46 < kakimir> somehow
2018-11-27T02:48:45 < aandrew> there we go

2018-11-27T02:49:32 < aandrew> so that's pretty cheap, and in 2 weeks too
2018-11-27T02:50:33 < kakimir> where?
2018-11-27T02:51:00 < con3> kakimir: I'm not sure what's going on. Trying to figure out, will let you know..

2018-11-27T08:55:16 < Haohmaru> from ess tea
2018-11-27T08:56:25 < dongs> there are tons
2018-11-27T08:56:32 < dongs> F107 in 64pin has ethernet

2018-11-27T08:57:08 < Haohmaru> ah, right.. i forgot i got a few other checkboxes checked
2018-11-27T08:57:08 < dongs> all teh F4 shit is 100pin.
2018-11-27T08:57:28 < dongs> there's lots of ethernet code for F1, its been around forever.,
2018-11-27T08:57:30 < dongs> and works well
2018-11-27T08:58:49 < Haohmaru> i need cryptographics sh*t as well, maybe mbedtls
2018-11-27T08:59:01 < dongs> its not like F1 can't do that
2018-11-27T08:59:23 < Haohmaru> but i think a true random number generator is a must in my case, and i guess that's what "RNG" is for in cubemx
2018-11-27T08:59:46 < dongs> there's rng and trng.
2018-11-27T08:59:56 < dongs> you could always just generate  random shit from a floating ADC input.
2018-11-27T09:00:00 < Haohmaru> ah, to the RNG is not really a TRNG
2018-11-27T09:00:02 < dongs> i mean, thats how 'rng' works anyway.
2018-11-27T09:00:16 < Haohmaru> i don't think that's a gud idea
2018-11-27T09:00:20 < dongs> good luck
2018-11-27T09:01:16 < Steffanx> Just use crt as input
2018-11-27T09:01:42 < Haohmaru> most of the cortex M chips i saw from different manufacturers seems to have just "ethernet MAC" and if i understand correctly - i need to add a PHY chip
2018-11-27T09:01:52 < Haohmaru> right?
2018-11-27T09:02:27 < Haohmaru> crt is pseudo-random
2018-11-27T09:05:30 < dongs> the same as ST
2018-11-27T09:06:06 < jpa-> considering you need to add a PHY chip anyway, if you want to use smaller controller and speed is not critical, you could just use one of the spi-connected ethernet chips
2018-11-27T09:07:21 < jpa-> and then you can also just steal all the arduino ENC28J60 codes

2018-11-27T10:35:38 < mitrax> i want to time precisely the accuracy of my STMF4 LSE clock (for calibration purpose) using an external 10Mhz reference clock, the LSE clock can be tied internaly to the TIM5 channel 4 input (that's the only timer it can be tied to), the problem is the maximum prescaler value for the capture input is /8 which means i'll be measuring a 8/32.768 period i.e 244.14µs with an accuracy of 0.1µs 
2018-11-27T10:35:38 < mitrax> (period of the reference clock) which is not accurate enough, i'd like to do the measurement on a e.g 10 sec window, it should be possible to use TIM5 as a regular timer with a higher prescaler value and use its output as input of another timer for the capture and compare with the reference clock right?

2018-11-27T10:43:20 < mitrax> it is, but the problem is not the timer resolution but the fact i'm not sure i can use capture and compare for a period of my input signal (my LSE clock) longer than input_period * 8 (the max prescaler value for the input capture)
2018-11-27T11:39:53 < kakimir> why doesn't visual studio accept my table initialization
2018-11-27T11:42:42 < kakimir> maybe it's c++ problem

2018-11-27T11:47:20 < Haohmaru> yeah, you need to change it then
2018-11-27T11:47:23 < karlp> don't specify the number of elements?
2018-11-27T11:47:43 < kakimir> I need to
2018-11-27T11:47:55 < Haohmaru> i suspect the issue has to do with the ".member = value" syntax
2018-11-27T11:47:57 < kakimir> use that number elsewhere too
2018-11-27T11:48:01 < Haohmaru> C++ doesn't like that
2018-11-27T11:48:02 < karlp> does c++ let you do .name = blah?

2018-11-27T11:48:04 < karlp> yeah

2018-11-27T11:49:37 < karlp> you can see them.
2018-11-27T11:49:49 < karlp> isn't that {x : blah} sthi just in the "short" constructors?
2018-11-27T11:50:02 < karlp> if you want to declare an array of structs, you can't use that syntax can you?

2018-11-27T11:50:40 < karlp> what would you be getting a medal for?
2018-11-27T11:50:50 < marble_visions> hi all, i've got a bunch of uint32_t's coming in from a byte array, so i've got macros like ARRAY_TO_U32().. is this type of serialization/deserialization standardized in some compiler headers?
2018-11-27T11:50:53 < Haohmaru> for patience
2018-11-27T11:51:04 < Haohmaru> and artificial optimism
2018-11-27T11:51:18 < marble_visions> linux has le_to_be32() and whatnot but that's not what i'm after
2018-11-27T11:51:42 < Haohmaru> wut'cha trying to do with them intz?
2018-11-27T11:51:59 < karlp> if you want to be safe, you use mask and shifts to construct your ints.
2018-11-27T11:52:05 < karlp> if you want tobe unsafe, type pun.
2018-11-27T11:52:25 < karlp> some libraries will have macros for this, but there's no standard c headeers that include it.
2018-11-27T11:52:28 < marble_visions> Haohmaru: smuggling them in the system over the wire
2018-11-27T11:52:50 < Haohmaru> no idea wut that meanz
2018-11-27T11:53:02 < Haohmaru> std::smuggle ;P~
2018-11-27T11:53:06 < marble_visions> karlp: yes, definitely mask and shift, in a macro. but i was wondering about standards. pity 
2018-11-27T11:53:28 < Haohmaru> do you want to like, reverse the order of the bytes?
2018-11-27T11:53:29 < marble_visions> Haohmaru: haha
2018-11-27T11:53:46 < marble_visions> Haohmaru: sometimes, but it depends on the platform
2018-11-27T11:54:01 < marble_visions> so it needs to be target dependent
2018-11-27T11:54:04 < Haohmaru> for that, gcc has __builtin_bswap
2018-11-27T11:54:27 < Haohmaru> and you could combine it with a fancy template or constexpr or something if you feel fancy

2018-11-27T11:56:26 < marble_visions> Haohmaru: nice! builtins are compiler-specific, right?
2018-11-27T11:57:01 < karlp> marble_visions: if you'r emasking and shifting, then no, you don't do anything platform specific.
2018-11-27T11:57:38 < marble_visions> karlp: yes
2018-11-27T11:58:18 < kakimir> how do i do C in visual studio?
2018-11-27T11:58:57 < marble_visions> kakimir: i've seen coworkers do it, it might be possible :D
2018-11-27T11:59:15 < karlp> marble_visions: no. you don't.
2018-11-27T11:59:23 < kakimir> activate secret mode
2018-11-27T11:59:27 < karlp> the mask and shift operations are always the same.
2018-11-27T11:59:37 < karlp> you have defined bit order for the wire bytes.
2018-11-27T11:59:50 < Haohmaru> marble_visions yes..
2018-11-27T11:59:56 < marble_visions> karlp: i meant yes as in "i agree", sorry.
2018-11-27T12:00:02 < karlp> ok :)
2018-11-27T12:08:58 < marble_visions> the __builtin_bswap looks really sexy, but i'd like to keep my code as portable as possible
2018-11-27T12:09:03 < marble_visions> Haohmaru: ^
2018-11-27T12:09:37 < karlp> mask and shift it is.
2018-11-27T12:10:35 < Haohmaru> hm, i wonder if C++ would have some standard byteswap sh*t maybe
2018-11-27T12:11:47 < kakimir> changed file extension to .c and now it's broken
2018-11-27T12:12:19 < karlp> not sure how you would try and use byteswap anyway.
2018-11-27T12:12:30 < karlp> if you take bytes and mask and shift, you have one set of code, all the time.
2018-11-27T12:12:36 < kakimir> what
2018-11-27T12:12:45 < kakimir> pch.h include to top of file
2018-11-27T12:12:46 < karlp> ifyou have bytes and try and cast to ints and byteswap, you've entered the world of per platform code.
2018-11-27T12:12:47 < kakimir> and it works
2018-11-27T12:13:53 < kakimir> marble_visions: how to do c project is if not by using c file templates that are not included - is to just change all source files to .c
2018-11-27T12:13:58 < dongs> < marble_visions> the __builtin_bswap looks really sexy, but i'd like to keep my code as portable as possible
2018-11-27T12:14:05 < dongs> if you used a real compiler
2018-11-27T12:14:21 < dongs> it would replace a << 24 | a << 16 etc type shit with a proper arm instruction
2018-11-27T12:14:27 < dongs> wehn needed.
2018-11-27T12:14:35 < zyp> yeah, gcc should do that
2018-11-27T12:14:42 < dongs> didnt last i cared to check
2018-11-27T12:14:46 < dongs> but keil worked
2018-11-27T12:14:49 < dongs> so ~shrug~
2018-11-27T12:15:02 < karlp> unless you'ðre looking at the asm, who cares? :)
2018-11-27T12:15:13 < dongs> when i was doing  sensor data swaps in uint16
2018-11-27T12:15:15 < marble_visions> dongs: shifts are indeed done with the barrel shifter, both with gcc and keil
2018-11-27T12:15:26 < zyp> not shifts, byteswaps
2018-11-27T12:15:37 < dongs> marble_visions: no, it would replace stuff like uint16_t foo = a << 8 | b; with a bswap
2018-11-27T12:15:45 < zyp> decent compilers recognize the pattern and substitute a byteswap instruction
2018-11-27T12:15:54 < marble_visions> oooooooooh
2018-11-27T12:16:00 < marble_visions> nice.
2018-11-27T12:16:21 < marble_visions> indeed there was an instruction like that
2018-11-27T12:17:07 < karlp> if only marble_visions wanted byte swaps....
2018-11-27T12:17:17 < dongs> i donno wat he wants, i didnt read
2018-11-27T12:17:29 < dongs> i was just here to promote keil :p
2018-11-27T12:17:31 < marble_visions> maybe it's left out of -O0 and enabled at -O1/2
2018-11-27T12:17:34 < karlp> they want struct.unpack("!l")
2018-11-27T12:17:40 < dongs> fuck python
2018-11-27T12:17:44 < karlp> nothing's turned on at -O0 dummy
2018-11-27T12:17:56 < karlp> you understood what I meant from the python though :)

2018-11-27T12:20:12 < marble_visions> dongs: is the keil compiler armcc or something else?
2018-11-27T12:20:19 < dongs> armcc, and now armclang

2018-11-27T12:23:29 < karlp> though could perhaps be written differenytly to help it.
2018-11-27T12:23:48 < dongs> errr
2018-11-27T12:23:57 < dongs> thats cuz you wrote shit
2018-11-27T12:24:12 < dongs> you just need to do uint32_t *ptr = wiredata;
2018-11-27T12:24:16 < dongs> and process it in 4 byte blocks
2018-11-27T12:24:19 < dongs> with rev or wahtever
2018-11-27T12:24:19 < karlp> that's not portable :)
2018-11-27T12:25:12 < marble_visions> dongs: your wiredata may not be aligned for a recast like that
2018-11-27T12:25:21 < karlp> you can do my way, and have _one_ code base that _always_ works.
2018-11-27T12:25:41 < karlp> or you can type pun, byteswap based on target platform, and hope you have no alignment issues.
2018-11-27T12:28:05 < dongs> is there a better instruction in asm than waht gcc is using for your example?
2018-11-27T12:28:07 < marble_visions> i'd rather have it working 
2018-11-27T12:28:20 < dongs> is that shit compiled with O3
2018-11-27T12:28:20 < karlp> dongs: no idea, I don't look at asm until things break.
2018-11-27T12:28:25 < dongs> because it looks literally same as your code
2018-11-27T12:28:37 < karlp> but byteswpa is definitely not what you want if you want portable
2018-11-27T12:30:42 < karlp> you can make it a little smaller by doign it in int16s first: https://paste.jvnv.net/view/j87jj
2018-11-27T12:31:05 < dongs> lets see what keil does
2018-11-27T12:31:35 < karlp> -O3 does a different code, but still 8 ops
2018-11-27T12:32:25 < karlp> heh, x86 is funny
2018-11-27T12:32:43 < karlp> it recognises the byte by byte, but fials on the uint16 version
2018-11-27T12:32:56 < karlp> https://paste.jvnv.net/view/RqIvD
2018-11-27T12:33:19 < karlp> so arm-none-eabi-gcc hasn't got all the smarts of x64 gcc yet...
2018-11-27T12:33:55 < karlp> so I'd sya, "write the byte by byte, let the compilers figure it out, and if they don't know, they will eventually"
2018-11-27T12:34:01 < dongs> http://bcas.tv/paste/results/QFr7me36.html

2018-11-27T16:18:48 < aandrew> dongs: the cx93whatever? there are two, an earlier/cheaper one that has fixed JPEG profiles and a bigger one whcih you can upload your own custom JPEG tables to
2018-11-27T16:19:04 < dongs> yeah wahtever is the only thign that exists
2018-11-27T16:19:09 < dongs> i jokingly recommended it for some project once
2018-11-27T16:19:16 < dongs> i didn't know anyone would actualyl seriously use that in 2018
2018-11-27T16:19:30 < aandrew> not in 2018 no, but in 2015 yes
2018-11-27T16:19:58 < aandrew> actually I think I used the litter/shittier one before that
2018-11-27T16:20:08 < aandrew> in the snap petz project
2018-11-27T16:20:26 < aandrew> https://wowwee.com/snappets/
2018-11-27T16:20:32 < aandrew> that was a dumb project 
2018-11-27T16:20:38 < aandrew> BLE JPEG camera, wtf
2018-11-27T16:20:44 < dongs> laff
2018-11-27T16:21:31 < aandrew> but hey, that specific project spun off probably a half mil in development work over the next few years and set me on one of my current projects with nrf
2018-11-27T16:21:52 < aandrew> that was my first exposure to nrf51
2018-11-27T16:24:41 < sync> wtf aandrew 
2018-11-27T16:24:45 < sync> wtf is that shit

2018-11-27T16:25:40 < aandrew> shitty stupid little project, but made wowwee a lot of money (not as much as robosapien or mip mind you) and like I said, set me on a pretty lucrative career path
2018-11-27T16:26:20 < sync> yeah but why would they make something at that point in the game
2018-11-27T16:26:41 < dongs> wowee made some retarded shit
2018-11-27T16:26:48 < aandrew> yep
2018-11-27T16:26:52 < dongs> so this is actually not all that surprising
2018-11-27T16:27:03 < aandrew> I'm still kind of pissed that their "personal assistant" robot was dumped
2018-11-27T16:27:13 < aandrew> I laid out an entire panel of boards just for that thing
2018-11-27T16:28:50 < aandrew> nice stm32 on the low level board too (motors, sensors, ble, etc.), some weird ass qualcomm SOM on the high level board, a "face" board with like 96 RGB addressable LEDs, battery charger board, few others I can't remember now either
2018-11-27T16:29:02 < aandrew> boards made, sent off ot mfg and they pulled the plug
2018-11-27T16:30:58 < mitrax> dongs: nevermind my question from earlier, i'm retarded, i didn't realize since the counter keeps running after capture i can still add the difference values each time the capture interrupt is triggered and hence do the measurement on several periods of the input signal for better accuracy

2018-11-27T17:48:48 < zyp> haha, wat
2018-11-27T17:48:59 < bitmask> I'm using xt30, they are a lot smaller than I expected but they will dof ine
2018-11-27T17:49:26 < zyp> oh, didn't know they had made a scaled down version

2018-11-27T17:54:18 < karlp> no idea, I'm jsut wondering where it came from that there was a special need for an unknown vendor to start making them, and for the connector people to not make a part for it too
2018-11-27T17:54:27 < zyp> these are simple polarized connectors with high current capacity
2018-11-27T17:54:34 < englishman> hobbyking is a pretty big mfg
2018-11-27T17:54:49 < englishman> in the end they are just polarized shrouds for bullet connectors
2018-11-27T17:54:55 < zyp> I figure the original need was that the other rc connectors were pretty shit
2018-11-27T17:55:09 < englishman> yeah like DEANS
2018-11-27T17:55:13 < zyp> yeah

2018-11-27T18:03:18 < qyx> you should ask them
2018-11-27T18:03:22 < englishman> 10 or 12 gauge i guess
2018-11-27T18:04:39 < sync> interesting
2018-11-27T18:10:54 < qyx> but talking about xt30/60/90, personally I would fear to use them in a product
2018-11-27T18:11:05 < qyx> I would rather use some molices instead
2018-11-27T18:11:37 < qyx> uhm, how do you say plural of "molex"
2018-11-27T18:11:41 < karlp> yeah, 60A plug wire to wire really does seem hard to find :) 
2018-11-27T18:11:59 < zyp> qyx, depends on the product
2018-11-27T18:12:05 < qyx> true
2018-11-27T18:12:17 < karlp> I'm somewhat more curious how 60A with just a push connection is considered happy land :)
2018-11-27T18:12:30 < karlp> I would expect it would need serious latching /locking
2018-11-27T18:13:03 < qyx> it is rc world, if it catches fire, it doesn't matter much

2018-11-27T18:13:52 < zyp> it's a matter of allowable temperature rise too

2018-11-27T18:50:38 < Sadale> Well, I'm just wondering. I'm a newbie :c
2018-11-27T18:51:10 < Sadale> Now I'm thinking about how do I connecting an audio jack output to a microcontroller ADC.
2018-11-27T18:51:20 < Sadale> more like I have a problem. But I don't know the solution :/
2018-11-27T18:51:24 < Streaker> through a capashitter
2018-11-27T18:51:54 < Streaker> I might not have the spilling down exact
2018-11-27T18:52:19 < Sadale> well, I tried that. Too bad I don't have a oscilliscope to check what's wrong.
2018-11-27T18:55:02 < qyx> Sadale: simple solution https://people.ece.cornell.edu/land/courses/ece4760/labs/f2014/AnalogIn.png
2018-11-27T18:55:47 < Sadale> qyx, I see. I'll try this one again. BTW, what should be the value of capacitor and resistor? How are they picked?
2018-11-27T18:55:50 < qyx> better solution https://i.stack.imgur.com/TOYS1.png
2018-11-27T18:56:03 < Sadale> looks cool!
2018-11-27T18:56:04 < qyx> even better: add some protection
2018-11-27T18:56:35 < Sadale> For both of the circuit, how do you pick the resistor and capacitor value?
2018-11-27T18:58:09 < Sadale> anyway, thanks a lot for the circuits. I'll try them.
2018-11-27T18:58:36 < qyx> the dc-blocking cap and biasing resistors basically form a high pass filter (in the simple schematic)
2018-11-27T18:58:48 < qyx> also there is an AC input impedance
2018-11-27T18:59:00 < emeryth> Sadale: http://www.muzique.com/lab/buffers.htm
2018-11-27T18:59:15 < qyx> just pick anything you have around and it will work ~somehow
2018-11-27T18:59:18 < Sadale> ahh. I see. So the cap really just remove the DC component.
2018-11-27T18:59:30 < Sadale> I see. Thanks a lot qyx. And I'm now reading the link from emeryth 
2018-11-27T18:59:33 < qyx> 1u cap, 10k resistors or so

2018-11-27T19:01:11 < qyx> (err: AC input impedance = ADC input impedance)
2018-11-27T19:02:39 < Sadale> hmm. What's the use of ADC input impedance? Isn't having less ADC input impedance allowing the capacitor inside the ADC getting charged more quickly?
2018-11-27T19:04:59 < qyx> you want to drive the ADC with low output impedance to avoid conversion errors as you say
2018-11-27T19:05:40 < qyx> hence the buffers as emeryth says
2018-11-27T19:07:34 < Sadale> ahh. I see. cool!

2018-11-27T21:18:52 < jadew> The District Police Commander Michael Angucia said that "due to public outcry from the people and local leaders, police had no alternative but to provide security on the streets to restore serenity in town, adding that some people have fled town and abandoned business in Mbale." The paper says that since the Bamasaba tribe began its forced coercion campaign, 220 people have been circumcised.

2018-11-28T00:05:24 < PeterM> and?
2018-11-28T00:05:52 < PeterM> no?
2018-11-28T00:06:04 < PeterM> yea, i get that
2018-11-28T00:06:52 < PeterM> but what does it matter, if you make enough money to pay for another acct, your resources and make a profit before  you get banned, it doesnt matter
2018-11-28T00:09:53 < PeterM> except 2 things, 1, detection has to be slow, it has to gather enough "evidence", otherwise too many false positives, and 2, the turnaround time of a production and qa team is much slower than some hack jobn macro writer

2018-11-28T00:20:50 < jadew> according to that, if you buy bitcoin now, by 25 you'll have 20 times that amount
2018-11-28T00:21:01 < jadew> that would be a good rate on investment
2018-11-28T00:21:19 < jadew> (amazing really)

2018-11-28T00:24:12 < kakimir> old 2 channel rigol
2018-11-28T00:24:13 < jadew> it's probably one of the safest ways to store value
2018-11-28T00:24:31 < karlp> hehe, thinking diamonds are a limited commodity
2018-11-28T00:24:46 < PeterM> until running a particle accelerator is less expensive than gold
2018-11-28T00:24:53 < jadew> hehe
2018-11-28T00:25:09 < kakimir> I should invest in stuff what I do

2018-11-28T00:30:51 < PeterM> jadew yeah
2018-11-28T00:31:24 < jadew> the cost of purchase/selling kills your proffits (I think there's a mandatory tax or something)
2018-11-28T00:32:06 < PeterM> i think the feels are something like 10%
2018-11-28T00:32:21 < PeterM> so unless your gains are >> 10% you lose
2018-11-28T00:32:37 < jadew> yeah, something silly like that
2018-11-28T00:33:06 < jadew> the state takes most of that
2018-11-28T00:34:18 < PeterM> what have i done....
2018-11-28T00:35:03 < PeterM> moving back to electronics;  damn high speed mosfet drivers with chargpumps are either rare or expensive
2018-11-28T00:36:13 < PeterM> something that uses n channel fets in the high side that may need 100% dutycycle, but also needs to be PWMable at decent speeds
2018-11-28T00:37:25 < Steffanx> Ne555 your own charge pump
2018-11-28T00:39:13 < PeterM> 1, my net didnt recomnnect until about an hour and a half ago and i dont troll the logs sorry
2018-11-28T00:39:44 < PeterM> Steffanx i was considering it but i need to do that for like 10 outputs

2018-11-28T04:18:35 < englishman> not at home, who cares
2018-11-28T04:18:42 < englishman> not at work either, who cares
2018-11-28T04:30:25 < PeterM> i do it because its cheap (a few 18650s and a tiny dc ups), and it keeps the wifi on if the power goes out

2018-11-28T05:33:30 < con3> but only one callback is called, the other buffer's callback doesn't get called when it's filled
2018-11-28T05:33:45 < con3> Not using cache at all

2018-11-28T05:57:06 < aandrew> hm, looks like I'd end up spending around US$10k-12k to set up a stencil screener, moderately useful (4 head w/ vision) pick and place and reflow
2018-11-28T05:57:40 < aandrew> not to mention needing a decent air compressor and air conditioning (filter/humidity) system and a way to wash the boards after
2018-11-28T05:57:46 < aandrew> optical inspection as well would be extra
2018-11-28T05:58:07 < aandrew> englishman: for a new startup trying to do it inexpensively, what is it, about $20k all-in to get set up?
2018-11-28T05:58:44 < englishman> dont bother
2018-11-28T05:59:00 < englishman> nothing worthwhile costs 20k
2018-11-28T05:59:31 < englishman> you'll end up with chinese garbage barely able to place 0603
2018-11-28T05:59:39 < aandrew> what's "worthwhile" mean - where does the money/time get eaten up with teh cheaper machines
2018-11-28T05:59:52 < aandrew> misplacements, jams, something else?

2018-11-28T06:00:58 < englishman> you are still left with pasting and reflow
2018-11-28T06:01:05 < aandrew> I'm seeing smallsmt (german) machines with 4 heads, 90 some odd feeders, servos and ballscrew system for $10k
2018-11-28T06:01:12 < englishman> yeah looks good on paper right
2018-11-28T06:01:22 < aandrew> yes, that's what I'm saying, decent paste application is tricky
2018-11-28T06:01:24 < englishman> smallsmt is maker filth
2018-11-28T06:01:27 < aandrew> we need dongtech for that
2018-11-28T06:01:34 < aandrew> englishman: even their higher end stuff?
2018-11-28T06:01:46 < englishman> what does higher end mean to you
2018-11-28T06:01:57 < englishman> more shitty cameras?
2018-11-28T06:02:00 < englishman> more wobbly nozzles?
2018-11-28T06:02:07 < aandrew> well that's kind of what I'm asking as the inexperienced one
2018-11-28T06:02:10 < englishman> windows 7 instead of XP?
2018-11-28T06:02:11 < aandrew> I don't know the common failure modes
2018-11-28T06:02:34 < aandrew> I'd love to get an old siplace but even those are constantly needing maintenance
2018-11-28T06:02:37 < englishman> just dont bother with low quantity stuff, pay to have it done
2018-11-28T06:02:43 < englishman> yes
2018-11-28T06:02:56 < englishman> and start at about 30k for shit with 10k hours on it
2018-11-28T06:03:12 < aandrew> yes
2018-11-28T06:03:14 < englishman> and they are meant for real assembly lines, so you cant do this or that, need another machine
2018-11-28T06:03:27 < aandrew> englishman: did I tell you, the local people will do the assembly for ~$1000/panel?
2018-11-28T06:03:36 < englishman> yeah you blogged in here
2018-11-28T06:03:57 < englishman> when will it be done
2018-11-28T06:04:08 < aandrew> I ballparked the BOM costs and they're about 90% of that. they're making <$100/panel
2018-11-28T06:04:11 < aandrew> 2 weeks
2018-11-28T06:04:26 < englishman> cool
2018-11-28T06:04:28 < aandrew> I feel bad for them because they're hurting for business
2018-11-28T06:04:38 < aandrew> but this is a really tough country to be a mfg
2018-11-28T06:04:43 < englishman> depends
2018-11-28T06:05:23 < englishman> if you go and spend 300k on shit and 10k/month on rent and dont have any customers, or want to work 8 hours a day, thats on you
2018-11-28T06:05:50 < aandrew> sure
2018-11-28T06:06:15 < aandrew> I just hate trying to deal with fitting into someone else's schedule which is why I'm lazy-evaluating doing it on my own
2018-11-28T06:06:27 < englishman> theres one public tender that keeps coming back up, they cant find an assy house
2018-11-28T06:06:31 < englishman> its like a 200k project
2018-11-28T06:06:32 < englishman> noone has times
2018-11-28T06:06:40 < aandrew> but you're absolutely right, it's a serious undertaking and for the twice every year or two that I actually need to do assembly it's not there yet
2018-11-28T06:07:01 < aandrew> englishman: what's the profit on that $200k
2018-11-28T06:07:07 < aandrew> i.e. is it worth it to make time for it
2018-11-28T06:07:16 < englishman> depends on labour cost
2018-11-28T06:07:19 < englishman> maybe 80k
2018-11-28T06:07:25 < englishman> gross
2018-11-28T06:07:30 < aandrew> that's not terrible, depending on labour as you said
2018-11-28T06:08:00 < englishman> one part had to go thru a vendor channel, they gave me the other companies that quoted the project
2018-11-28T06:08:20 < englishman> they are all able to do it, but noone picked it up
2018-11-28T06:08:32 < aandrew> hm
2018-11-28T06:08:55 < englishman> the big places wont bother with that
2018-11-28T06:09:02 < englishman> small places probably couldnt deliver
2018-11-28T06:09:15 < englishman> 80k in 45 days is not bad if you know what youre doing

2018-11-28T06:16:25 < aandrew> it would seem (inexperienced opinion here) that you want to use the heads to do as little forceful work as possible, as they need ot remain accurate
2018-11-28T06:18:15 < aandrew> do any of these use fiducials on the board? 
2018-11-28T06:22:48 < aandrew> *nods* I spent some time servicing siemens feeders
2018-11-28T06:22:52 < aandrew> those things are like swiss watches
2018-11-28T06:23:09 < aandrew> thousands of tiny screws, fine gearing
2018-11-28T06:23:29 < aandrew> they even had little dumpsters where missed components would fall in to and you'd periodically empty
2018-11-28T06:23:46 < aandrew> i.e. they didnt just rattle around and get caught in a gear, they were designed to fall into a specific place and stay there
2018-11-28T06:24:45 < aandrew> the siemens feeders had a micro in them and had to be calibrated too. the procedure for calibration involved an expensive jig and some embedded sw to talk to the mcu in the feeder
2018-11-28T06:25:20 < aandrew> yes that's kind of the situation I'm in
2018-11-28T06:26:09 < aandrew> at that awkward place where hand assembly (especially with bgas and 0402s) becomes tedious and error prone, but I also spent a good month massaging BOMs into various formats for assembly houses, chasing down answers to questions and basically interacting so I could get quotes
2018-11-28T06:29:19 < aandrew> *nods*
2018-11-28T06:29:32 < aandrew> it's interesting, but I won't be spending that kind of cash anytime soon

2018-11-28T06:33:02 < aandrew> $5k for 5 panels without knowing the BOM cost also implies that that's $5k + parts, which is really pricey
2018-11-28T06:33:03 < dongs> ah okay. sure im serious as long as you're paying

2018-11-28T06:50:05 < aandrew> this is very very true

2018-11-28T06:50:27 < aandrew> it worked great until it didn't, becuase i don't print colour all that often
2018-11-28T06:51:35 < aandrew> ended up getting a $50 print head from ali and installing it. it works great again but I probably spent a good couple days between trying to unclog it several times and increasing order of desperation, researching what to replace and how to replace it, buying it and installing it

2018-11-28T11:15:52 < Ecco> Hi
2018-11-28T11:16:17 < Ecco> Is there a reference schematics to interface an SPI flash rom with an STM32
2018-11-28T11:16:47 < Ecco> Currently I just wired both chips together, w/o any cap or anything. It seems to be working. But I wonder if it's by accident :)
2018-11-28T11:19:01 < Haohmaru> you'd want to put some pull resistors on the SPI signals, and on the chipselect
2018-11-28T11:19:05 < Haohmaru> perhaps-ish
2018-11-28T11:19:27 < Haohmaru> or just see the datasheets of both chips if they require something funky
2018-11-28T11:20:42 < karlp> you might want decoupling/bulk on the spi flash to support writing nicely. pulls may or may not be needed, depending on how fast you want to go, and what default states are.
2018-11-28T11:25:33 < Ecco> ok
2018-11-28T11:25:53 < Ecco> I have no clue how to pick those parts though. Is there some reference I could read?
2018-11-28T11:25:59 < Ecco> (thanks, by the way ^^)
2018-11-28T11:26:36 < karlp> what does the datasheet for the spi flash say?
2018-11-28T11:26:45 < karlp> 100n is a good chocie :)
2018-11-28T11:26:52 < karlp> also: http://zhiminhk.com/content/?595.html
2018-11-28T11:27:16 < Ecco> karlp: well, it doesn't seem to be saying anything…
2018-11-28T11:27:46 < Ecco> https://www.adestotech.com/wp-content/uploads/AT25SF641_111.pdf
2018-11-28T11:28:12 < Ecco> karlp: are you sure that was the right link? :)
2018-11-28T11:28:24 < karlp> not relevant to your problems, but yes :)
2018-11-28T11:28:28 < Ecco> oh, ok :)
2018-11-28T11:29:12 < Ecco> Maybe there's a Nucleo board with SPI flash whose design I could steal from
2018-11-28T11:30:22 < Ecco> Ha, apparently, 32F412GDISCOVERY
2018-11-28T11:33:02 < qyx> do they usually bomb those?
2018-11-28T11:38:23 < Ecco> Hmm, that schematic is very interesting
2018-11-28T11:38:37 < Ecco> they do net length matching for QSPI flash
2018-11-28T11:38:44 < Ecco> Is that useful?
2018-11-28T11:39:42 < karlp> depends whether you want to run it at 100Mhz or not?
2018-11-28T11:40:04 < Ecco> Well, yeah maybe
2018-11-28T11:40:43 < Ecco> They don't add any decoupling on the QSPI pins
2018-11-28T11:42:41 < karlp> they might consider enough decoupling in general for it's supply
2018-11-28T11:42:54 < Ecco> ok

2018-11-28T11:43:27 < Ecco> just like Haohmaru said
2018-11-28T11:43:37 < Ecco> What's the purpose of this one? Can't the STM32 do it?
2018-11-28T11:45:55 < Haohmaru> if the STM32 has a resistor.. ;P~
2018-11-28T11:46:13 < Ecco> I don't get it :)
2018-11-28T11:46:17 < karlp> probably keeps it in powered down state until it's booted up?
2018-11-28T11:46:38 < Haohmaru> is NCS == chipselect?
2018-11-28T11:49:43 < Ecco> I guess not-ChipSelect
2018-11-28T11:53:06 < Haohmaru> well, if it's the chipselect pin, you'd want to be sure that the spi slave will only be "selected" by the spi master chip, in normal operation, and that it will definately not be "selected" otherwise
2018-11-28T11:53:24 -!- con3 [~kvirc@ml.sun.ac.za] has joined ##stm32
2018-11-28T11:53:33 < Haohmaru> so putting a pull up resistor there is a simple way to do that
2018-11-28T11:54:20 < Haohmaru> ..because the slave chip might get powered and be "ready to operate" sooner than the master
2018-11-28T11:55:06 < Haohmaru> and if the CS pin is only connected to a pin on the master, and that pin is in hi-Z - the chipselect will be floating
2018-11-28T11:56:11 < Haohmaru> so who knows.. it might catch a soviet radio station and decide to erase page8 ;P~

2018-11-28T12:15:30 < Ecco> thanks Haohmaru 
2018-11-28T12:16:41 < Ecco> In the disco board schematics, there's a first page with big green "blocks"
2018-11-28T12:16:45 < Ecco> How do I do this in Altium?
2018-11-28T12:17:06 < Ecco> (It gives an overview of the whole project, that's great)
2018-11-28T12:17:32 < karlp> read the manual? 
2018-11-28T12:17:37 < Ecco> Ha, that's a sheet symbol
2018-11-28T12:17:38 < Ecco> :)
2018-11-28T12:17:39 < PeterM> create component from sheet iirc
2018-11-28T12:17:41 < Ecco> yeah, that too
2018-11-28T12:18:06 < PeterM> yeah sheet symbol
2018-11-28T12:18:10 < Haohmaru> "Altium" sounds incomplete ;P~
2018-11-28T12:18:20 < Haohmaru> a word is missing
2018-11-28T12:18:27 < PeterM> "Altium by Prada"?

2018-11-28T12:19:48 < Haohmaru> Altium Pro HD Delux MK3
2018-11-28T12:20:16 < PeterM> Nah, that seems like more of a Mentor or Cadence name
2018-11-28T12:20:22 < Haohmaru> InnovAltium ;P~
2018-11-28T12:21:19 < Haohmaru> kakimir i'm not sure if you can use enumz in a preprocessor #if
2018-11-28T12:22:05 < Haohmaru> but if not - i'd expect teh compil0r/preprocess0r to vomit at you
2018-11-28T12:22:28 < Haohmaru> unless it doesn't care
2018-11-28T12:39:30 < kakimir> it didn't say a thing
2018-11-28T12:39:34 < kakimir> it just did wrong
2018-11-28T12:39:37 < kakimir> or right

2018-11-28T12:42:39 < Haohmaru> as i suspected
2018-11-28T12:42:50 < Haohmaru> use constexpr shizzle ftw
2018-11-28T12:43:03 < Ecco> Another thing I don't know how to do in Altium is having a port for multiple nets
2018-11-28T12:43:10 < Ecco> e.g. "LCD_[D0..D7]"
2018-11-28T12:43:20 < Ecco> How is it done?
2018-11-28T12:43:36 < Ecco> Should I just name it like that and Altium will pick it up?
2018-11-28T12:43:43 < Haohmaru> i guess with a "bus" thing.. but i've not use busses yet
2018-11-28T12:44:09 < Haohmaru> * not used
2018-11-28T12:44:20 < zyp> an array of same-named signals like that is a bus
2018-11-28T12:44:36 < zyp> if you want a group of distinct signals, you want a harness
2018-11-28T12:45:21 < Ecco> What I'm looking for is the way to define a port in Altium that designates a whole bus instead of a single net
2018-11-28T12:47:49 < zyp> just define a bus then :)
2018-11-28T12:48:29 < zyp> as for how, refer to the manual: https://www.altium.com/documentation/18.0/display/ADES/Sch_Obj-Bus((Bus))_AD
2018-11-28T12:49:16 < Ecco> thanks :)
2018-11-28T12:49:23 < Ecco> Oh, ok I get it
2018-11-28T12:50:57 < kakimir> hmm freeram() returns 0
2018-11-28T12:52:18 < kakimir> my program doesn't have heap
2018-11-28T12:53:39 < kakimir> so it's ram usage can be determined compile time
2018-11-28T12:54:24 < kakimir> afaik I't wouldn't have heap as I don't use malloc once
2018-11-28T13:09:05 < kakimir> if I use variable only in interrupt
2018-11-28T13:09:28 < kakimir> no volatile needed?
2018-11-28T13:13:50 < jpa-> sprinkle "volatile" randomly to your code, that's how real pros do it
2018-11-28T13:13:59 < kakimir> that is how I do it
2018-11-28T13:15:14 < kakimir> but yeah
2018-11-28T13:15:21 < kakimir> left it wo volatile
2018-11-28T13:16:28 < Haohmaru> i also sprinkle around const, and constexpr
2018-11-28T13:16:48 < Haohmaru> and sometimes inline
2018-11-28T13:16:49 < zyp> like a true pro
2018-11-28T13:16:55 < Haohmaru> yaaaas
2018-11-28T13:16:58 < dongs> bus stuff in altium is so shitty that its easier not to use it
2018-11-28T13:17:14 < dongs> it works in simple cases like ecco's autism im sure
2018-11-28T13:17:33 < dongs> but try combining bus + hierarchical design and RIP
2018-11-28T13:17:41 < dongs> or repeated blocks
2018-11-28T13:18:00 < zyp> why wouldn't that work?
2018-11-28T13:18:10 < dongs> REPEAT() + bus = good luck
2018-11-28T13:18:17 < dongs> because it doens't
2018-11-28T13:18:50 < dongs> It is recommended that net labels in a Bus only contain alpha characters. For example, if you named the Bus D2[0..7], when the design is compiled, this would be expanded to D20, D21 .. D27, which can potentially cause net name conflicts. heh
2018-11-28T13:19:11 < zyp> isn't the whole point of REPEAT() to pull out one signal from a bus?
2018-11-28T13:21:55 < zyp> are you talking about shit like making a bus of busses?
2018-11-28T13:23:02 < Haohmaru> a bus of busses sounds like a road crash incident with multiple busses

2018-11-28T13:26:08 < dongs> brave
2018-11-28T13:26:28 < zyp> works fine
2018-11-28T13:29:03 < zyp> how else are you supposed to use REPEAT if you don't want to connect all instances in parallel?
2018-11-28T13:38:11 < kakimir> codes work
2018-11-28T14:19:35 < zyp> running silly hardware tests today
2018-11-28T14:19:54 < Haohmaru> getting silly results? ;P~
2018-11-28T14:20:12 < zyp> no, all results so far have been "everything works as expected"
2018-11-28T14:20:22 < zyp> shit's just super tedious
2018-11-28T14:20:49 < zyp> this shit has two power inputs, separated by diodes
2018-11-28T14:21:35 < zyp> I just ran a couple runs proving that shit keeps working if one supply goes away and comes back and then the other goes away and comes back
2018-11-28T14:21:38 < Haohmaru> in my case: i prepare to connect the power cable or put my finger on the ON switch, i almost close my eyes and move back, then i power it on
2018-11-28T14:21:51 < Haohmaru> doesn't blow up -> success \o/
2018-11-28T14:21:58 < Haohmaru> QC PASSED \o/
2018-11-28T14:22:09 < zyp> and now I'm running the same shit again, just shorting out one of the supplies instead of turning it off
2018-11-28T14:22:25 < Haohmaru> hm
2018-11-28T14:23:10 < Haohmaru> if you're combining two DC voltage sources together with diodes - shorting one of them shouldn't be a problem, i think
2018-11-28T14:23:26 < PaulFertser> Haohmaru: don't you current-limit your lab psu for the first try?
2018-11-28T14:23:27 < zyp> exactly, there's no practical difference
2018-11-28T14:23:32 < qyx> doesn't your diodes diode well?
2018-11-28T14:23:45 < Haohmaru> PaulFertser u assume i use a lab psu ;P~
2018-11-28T14:23:56 < qyx> atx psu ftw
2018-11-28T14:24:32 < Haohmaru> well, no idea wut it is, the former collegue built it and stuffed it in an evil plastic box
2018-11-28T14:25:19 < zyp> but the test spec says I need to short out one of the supplies and run shit for ten minutes
2018-11-28T14:25:20 < PaulFertser> I've seen one china lab psu which had instructions suggesting to use one's "gut feeling" to set the current limiting because its internal "short circuit protection" (wtf?!) made it impossible to just set it when you connect the output terminals with a piece of wire.
2018-11-28T14:25:31 < zyp> and then I need to repeat that for four different scenarios
2018-11-28T14:25:52 < zyp> so I literally have to run ten minutes of this: https://bin.jvnv.net/file/Q6RVe.jpg

2018-11-28T14:28:19 < zyp> oh, and this happens with the electronics sitting in 85C ambient :)
2018-11-28T14:28:22 < Haohmaru> do you have to run this test just once, or for each and every device of that same kind?
2018-11-28T14:28:33 < Haohmaru> wot
2018-11-28T14:28:51 < Haohmaru> that's f*ckin hot
2018-11-28T14:29:14 < Haohmaru> so ur torturing yer device
2018-11-28T14:29:54 < zyp> nah, it's rated to handle it
2018-11-28T14:31:43 < jpa-> torturing is stuff like driving temperature between +100C and -20C every half hour while providing slight overvoltage to the supplies and slight overload to the outputs
2018-11-28T14:31:51 < zyp> the electronics are designed for up to 85C ambient inside the enclosure, we've specced the device to handle 60C outside the enclosure
2018-11-28T14:32:34 < zyp> we measured temperature rise earlier today, seemed like it gets around 15C hotter inside the enclosure than outside when at full load
2018-11-28T14:33:07 < jpa-> i once was in a project where we had that kind of test done to a device with supply voltage rating of 1000VDC; every time one of the devices failed the whole test room smelled for the rest of the day :P

2018-11-28T14:38:20 < zyp> so far the only difference we've measured are the voltage limits on the optoisolated inputs :p
2018-11-28T14:38:59 < zyp> at room temp they trigger down to 2.6V in, at -30 they trigger at 2.3V while at +85 they need 3.2V
2018-11-28T14:39:52 < zyp> which is all fine, because they are specced to work with 12-24V ±10%

2018-11-28T17:29:49 < Thorn> ads1220 is my new favorite adc
2018-11-28T17:30:35 < qyx> such expensive
2018-11-28T17:34:44 < karlp> local shop has them in stock, for ~10x price, but still cheaper than digikey's shipping (or tme's) and much cheaper than a new sandwhich grill in the office :)
2018-11-28T17:35:03 < aandrew> that's not expensive
2018-11-28T17:35:09 < karlp> nah, it's cheap enough
2018-11-28T17:35:13 < kakimir> https://www.youtube.com/watch?v=ZRP3bJPkF_Y kakipump musics
2018-11-28T17:35:23 < aandrew> I've got 5x LT2387-18 on my digitizer board. those are $98 apiece
2018-11-28T17:35:24 < karlp> but $1 vs $10 always annoys me, 
2018-11-28T17:35:35 < karlp> oh, the ads1220, nvm, sorry, center of my own universe
2018-11-28T17:36:03 < qyx> yeah, your thermal fuse seemd a bit suspicions to me
2018-11-28T17:36:09 < qyx> I saw it on them the other day
2018-11-28T17:36:25 < aandrew> 24 bits though, that is a nice little ADC - how many useful bits are you getting out of it?
2018-11-28T17:36:38 < karlp> saw it on what?
2018-11-28T17:36:54 < qyx> MAX31865 is similar if you don't need such bittness
2018-11-28T17:36:57 < qyx> karlp: on tme
2018-11-28T17:37:01 < karlp> heh
2018-11-28T17:37:39 < qyx> krive rucky
2018-11-28T17:37:44 < karlp> the sandwhich grill is one of those thermal cutoffs, a dial switch thingy, two elements.
2018-11-28T17:37:58 < karlp> nothing else other than a 240v led
2018-11-28T17:38:07 < karlp> so simple!

2018-11-28T17:42:34 < qyx> what are you planning to use it for?
2018-11-28T17:42:55 < Thorn> but it can do 3-wire rtd with no external components except 2 resistors (1  precision)
2018-11-28T17:43:15 < Thorn> with lead compensation and ratiometric measurement

2018-11-28T17:44:17 < qyx> the MAX part is even simpler
2018-11-28T17:44:19 < qyx> less bit though
2018-11-28T17:45:49 < Thorn> there are also ardweeno ekg projects with ads1220 on the net
2018-11-28T17:50:04 < aandrew> yes with probably 8 bits of useful range too :-)
2018-11-28T17:51:37 < kakimir> muh shit
2018-11-28T17:52:05 < kakimir> it's sweet to see stuff working
2018-11-28T17:57:24 < aandrew> yep
2018-11-28T18:03:59 < kakimir> I'm watching it like I watch paint to dry
2018-11-28T18:05:46 < aandrew> heh
2018-11-28T18:06:22 < qyx> how would you drive a couple (16) of SMD RGB leds
2018-11-28T18:06:46 < qyx> I imagine there could be some spi/i2c thing for it
2018-11-28T18:07:01 < aandrew> qyx: are these "dumb" RGB LEDs or those ws2812 type ones
2018-11-28T18:07:06 < marble_visions> dongs: so they've got arm cc and arm cc hpc edition, and arm cc has version 5 and version 6? https://developer.arm.com/products/software-development-tools/compilers/arm-compiler/downloads
2018-11-28T18:07:25 < marble_visions> and all is paid for
2018-11-28T18:07:30 < qyx> aandrew: none yet, i planned to use cheap dumb ones
2018-11-28T18:08:00 < aandrew> qyx: there are lots of LED drivers from TI on digikey. you use I2C or SPI like you assumed and just tell it what to make the LEDs do and it'll do the PWM to maintain whatever state you ask
2018-11-28T18:08:16 < qyx> \o/
2018-11-28T18:08:23 < qyx> I'll check

2018-11-28T18:10:18 < qyx> WS281x are not that expensive, they are huge though
2018-11-28T18:10:28 < aandrew> there is also SK6812
2018-11-28T18:10:31 < aandrew> I like those, they're smaller
2018-11-28T18:10:34 < aandrew> same drive
2018-11-28T18:10:34 < Thorn> there are 3.5mm versions
2018-11-28T18:11:29 < qyx> I plan to use them for a din rail enclosure blinky led panel
2018-11-28T18:11:56 < qyx> so maybe THT LEDs are better suited
2018-11-28T18:12:01 < qyx> or lightpipes and smd
2018-11-28T18:12:34 < aandrew> bivar makes some nice light pipes

2018-11-28T23:12:15 < kakimir> it it were to touch PERIOD_COUNT_MIN_CC10 it would activate 1.0A charging + hysteresis for that count threshold in next period
2018-11-28T23:12:54 < kakimir> and increase speed of period count to 200%
2018-11-28T23:18:19 < kakimir> around index 3400 battery charger stops pulling NCHRG pin down and mcu registers it as no charging and sets initialization counter for battery detection function so it stays out of deltaU operation and sets charging to 0.5A
2018-11-28T23:19:32 < kakimir> or actually it's software limit condition for fast charging there NCHRG stays pulled down a while after that
2018-11-28T23:20:27 < kakimir> 4.12volts or so where initial condition check sets initialization counter for battery detection
2018-11-28T23:21:32 < kakimir> thats why counter does runaway and deltaU stops updating

2018-11-28T23:38:22 < PeterM> is it well soldered?
2018-11-28T23:38:43 < johntramp> yes and i have seen this on multiple boards
2018-11-28T23:38:53 < PeterM> no idea
2018-11-28T23:39:25 < PeterM> i was thinking maybe it was not fully soldered and forming some sort of tuning fork, but alas, that is nto hte case
2018-11-28T23:41:16 < PeterM> gday
2018-11-28T23:42:31 < johntramp> PeterM: yeah it does look like that , i like your thinking though 
2018-11-28T23:48:24 < PeterM> i dont think that is relevent, he would be able to tell if the entire board was vibrating at 950 hz enough to cause that, unless  the qyro is right beside a big fat power inductor or cap
2018-11-28T23:49:24 < PeterM> nah, the boards were probably dropped hard in transit and it fucked the gyro, mems accels and gyros do weird shit when subject to big shhocks
2018-11-28T23:50:59 < englishman> which gyro
2018-11-28T23:52:51 < johntramp> sorry Cracki ,  went to grab a coffee
2018-11-28T23:55:21 < johntramp> the it's quite a simple board, just getting a photo for you
2018-11-28T23:58:57 < johntramp> the gyro vertical axis isn't right there, i think 10000 would equal 610 dps

2018-11-29T00:18:00 < johntramp> i have only tried 2 and both of them show it,  the oscillations seem to get a lot smaller though after a short time,  perhaps it is a transient as it changes state as i am using the mode where it drops sample rate when there is no movement
2018-11-29T00:19:02 < englishman> PeterM: datasheet says max accel is 10k G, how hard are you dropping your gyros? :)
2018-11-29T00:22:55 < johntramp> i did think maybe i need a bit more bulk capacitance on the imu, as the SMPS is a bit noisy on the 3v3 rail
2018-11-29T00:26:14 < PeterM> johntramp what kind of math are you doing on your data? if angular accell is pretty much 0, and you're going +/-5 with noise in the sampling time, i could see that geing a huge dw/dt
2018-11-29T00:27:58 < johntramp> there is no arithmetic here , this is just raw data
2018-11-29T00:28:46 < PeterM> i see, and one would expect the noise on the raw data to be atleast in the same order of magnitude for all axis

2018-11-29T00:49:13 < kakimir> names do not matter that much
2018-11-29T00:53:41 < kakimir> can I print macro value in error?
2018-11-29T00:53:46 < kakimir> error string
2018-11-29T00:56:07 < kakimir> no
2018-11-29T00:56:38 < mawk> insert in a string you mean kakimir ? yes
2018-11-29T00:56:44 < kakimir> just print "maan shit ain't gonna work here is a value from macro:"
2018-11-29T00:56:57 < kakimir> in compile time errors
2018-11-29T00:57:20 < kakimir> #error "message"
2018-11-29T00:57:25 < kakimir> #error MACRO
2018-11-29T00:57:26 < mawk> either you have a printf-like and you know how to do, either you do a macro like #define build_err_msg() "here is the macro value: " #MACRO
2018-11-29T00:57:46 < kakimir> I try first
2018-11-29T00:57:56 < kakimir> I'm just scared
2018-11-29T00:58:02 < mawk> you maybe need one more level of indirection, like #define build_err_msg() _build_err_msg() and #define _build_err_msg() "here is the macro value: " #MACRO
2018-11-29T00:58:09 < mawk> I don't remember
2018-11-29T01:02:21 < kakimir> error just prints the line with #error on it
2018-11-29T01:02:28 < kakimir> no matter what I think
2018-11-29T01:03:06 < kakimir> it's like any error
2018-11-29T01:03:31 < kakimir> it's just triggered by #error directive
2018-11-29T01:04:54 < kakimir> if you have error in some other line it prints the line in compile errors same way
2018-11-29T01:06:09 < kakimir> I don't think evaluated macros can be shown in compile errors
2018-11-29T01:09:03 < kakimir> code is done
2018-11-29T01:09:10 < kakimir> it didn't #error
2018-11-29T01:10:37 < mawk> #error "my macro is " #macro
2018-11-29T01:10:41 < mawk> this doesn't work ?
2018-11-29T01:11:03 < mawk> use something else than #error then
2018-11-29T01:11:08 < kakimir> I tried with only #error #macro
2018-11-29T01:11:10 < mawk> use some kind of pragma that allows macros, then #error
2018-11-29T01:11:10 < kakimir> lemme try
2018-11-29T01:13:10 < kakimir> 100%
2018-11-29T01:13:20 < kakimir> I'm checking macros
2018-11-29T01:13:35 < mawk> use a pragma to display an error message, then use #error to abort the compilation
2018-11-29T01:13:40 < mawk> pragmas are easier to manipulate
2018-11-29T01:13:47 < mawk> because you can do _Pragma(stuff);
2018-11-29T01:13:54 < mawk> and this can be constructed using macros
2018-11-29T01:14:08 < kakimir> how do I push evaluated macro value to compile output and then error?
2018-11-29T01:14:10 < mawk> also sometimes you need to nest macros to have enough indirection to evaluate every macro argument
2018-11-29T01:14:19 < mawk> yeah something like that

2018-11-29T01:51:27 < englishman> The initial hypothesis was that a micro-meteoroid impact resulted in a 2mm hole in the Orbital Module of MS-09. Russian crew members used Kapton tape to temporarily seal the leak while a permanent fix was devised.
2018-11-29T01:51:32 < englishman> kapton saves lives

2018-11-29T04:41:43 < dongs> damn thats awful
2018-11-29T04:43:01 < con3> So I need some help. The dma I'm using is in double buffer mode. Both the buffers are being filled correctly, for some reason when the second buffer is filled it's callback is never called. I can see that it is set in the registers, even setting the half-transfer complete callback for the second memory address does nothing, but the first memory addresses callback always gets called correctly. 
2018-11-29T04:43:16 < con3> Not sure what the hell is happening
2018-11-29T04:54:27 < aandrew> you've verified the interrupts are set up correctly and enabled?
2018-11-29T04:54:34 < aandrew> do you see the interrupt flags for transfer complete firing?
2018-11-29T04:54:40 < aandrew> er not firing but being set
2018-11-29T05:01:58 < con3> hey aandrew I'm triple checking, but it all looks fine, definetly being set
2018-11-29T05:02:19 < PeterM> dongs $10 says the schematic is equally hideous
2018-11-29T05:02:32 < dongs> oh it is

2018-11-29T05:04:22 < PeterM> looks like it could very easily and neatly fit on a single plage
2018-11-29T05:06:33 < dongs> each IC has its own page
2018-11-29T05:06:54 < aandrew> con3: interrupt priorities are configured correctly? that can fuck up an otherwise functioning system
2018-11-29T05:07:06 < aandrew> and dumb question, but interrupts are enabled? you've got timers firing or other interrupts working?
2018-11-29T05:07:28 < aandrew> dongs: you gonna charge him $5k too heh
2018-11-29T05:17:12 < con3> aandrew: I've configured it so that the dma is set up as high as possible while still being less than systick, etc. So I found the weird portion and digging a bit deeper. it shows that the first buffer's TCIE is set and once it's full the callback gets called. It also shows that the second buffer's TCIE is set, but once it's full the callback isn't called nor is the TCIF called for the second buff
2018-11-29T05:17:18 < con3> er in the multi-buffer
2018-11-29T05:17:47 < con3> I have two other spi lines also using DMA with callbacks which are working. It's only this damn multi-buffer where only one buffer is working

2018-11-29T12:44:03 < Ecco> Altium is throwing "Duplicate net names wire" error
2018-11-29T12:44:06 < Ecco> I don't get what this means
2018-11-29T12:44:47 < Haohmaru> maybe a a connection with two different net names
2018-11-29T12:44:52 < Ecco> yes
2018-11-29T12:44:55 < Ecco> is that not allowed?

2018-11-29T12:45:15 < Ecco> I'm using a hierarchical layout
2018-11-29T12:45:28 < Ecco> and I'd like to link two pins *within a sheet*
2018-11-29T12:45:37 < Ecco> without having to actually draw a line (would fuck the layout)
2018-11-29T12:45:39 < Haohmaru> i am not familiar with altium disast0r
2018-11-29T12:45:46 < Ecco> I used to do this with a port
2018-11-29T12:46:01 < Ecco> but ports are supposed to be visible "outside" of a sheet in hierarchical mode

2018-11-29T16:15:00 < dongs> the big one has the link, left top side of building
2018-11-29T16:15:06 < dongs> and one below it with kids has the name but no link
2018-11-29T16:17:29 < jadew> the big one says: "If you asked what I want the most, my answer would be that I want to go with my brother to Gloria"
2018-11-29T16:17:35 < jadew> not sure what Gloria is
2018-11-29T16:17:45 < dongs> glory hole
2018-11-29T16:18:08 < jadew> you're probably right
2018-11-29T16:18:25 < dongs> lol the smaller sign says titanic
2018-11-29T16:18:27 < jadew> it's fuzzy, but I guess it says hotels * resorts
2018-11-29T16:18:36 < dongs> not sure if thats a very good advertisement for a travel agency
2018-11-29T16:18:48 < jadew> haha
2018-11-29T16:19:25 < dongs> why are people parked like on the sidewalk
2018-11-29T16:19:35 < dongs> how do they even get in there like that
2018-11-29T16:19:50 < jadew> you've never parked on the sidwalk before?

2018-11-29T16:20:03 < dongs> no
2018-11-29T16:20:06 < dongs> there's a tree
2018-11-29T16:20:08 < dongs> and those metal poles
2018-11-29T16:20:14 < dongs> less than 2x length of the car
2018-11-29T16:20:40 < jadew> there's plenty of room there
2018-11-29T16:20:53 < jadew> the reason they're parked like that is probably because it's illegal to park on the road in that area
2018-11-29T16:21:09 < jadew> but there's no contravention for parking on the sidewalk :)
2018-11-29T16:21:49 < jadew> smart, eh?

2018-11-29T16:26:01 < Ecco> thanks dongs
2018-11-29T16:26:13 < Ecco> Quick question: what should I pay attention to when routing USB D+ and D-?
2018-11-29T16:26:21 < dongs> nothing, especially for stm32
2018-11-29T16:26:29 < dongs> full-speed usb will work over coat hangers
2018-11-29T16:26:39 < dongs> i mean you could make it a diff pair and wahtnot
2018-11-29T16:26:43 < dongs> but in reality its not gonna matter
2018-11-29T16:27:02 < Ecco> ok :)
2018-11-29T16:27:40 < Ecco> On a sample schematic by ST
2018-11-29T16:27:50 < Ecco> they do net length matching for QuadSPI and FSMC
2018-11-29T16:27:53 < Ecco> That seems reasonable
2018-11-29T16:28:07 < Ecco> they also add an "Impedance Constraint" for the FSMC. What's that?
2018-11-29T16:30:15 < Ecco> Also, other question: how do you compute the tolerance for trace length matching? Do you compute based on the speed of light?
2018-11-29T16:30:39 < Ecco> (I didn't do the math but I assume anything would be negligible at this speed)
2018-11-29T16:30:50 < dongs> whatever fullspeed USB spec deviation is, last i calculated it wouldstill work with something like 90cm length difference
2018-11-29T16:31:00 < Ecco> oh wow ok
2018-11-29T16:31:02 < dongs> so youve got absolutely nothing to worry about
2018-11-29T16:31:47 < Ecco> Let's do the math about the length matching in general though. 100 MHz signal. You want two traces to be in "sync", i.e. less than 10% of a period difference.
2018-11-29T16:31:54 < dongs> i wouldnt worry about qspi or fsmc matching either
2018-11-29T16:31:59 < dongs> none of those things run > 100mhz
2018-11-29T16:32:22 < dongs> i think SPI max is like 48mhz?
2018-11-29T16:32:25 < dongs> on F4
2018-11-29T16:32:31 < Ecco> So that's 1/100M = 10ns
2018-11-29T16:32:39 < Ecco> Yeah you might be right indeed
2018-11-29T16:32:54 < Ecco> so we want less than a ns of difference
2018-11-29T16:33:12 < Ecco> if I multuply this by the speed of light
2018-11-29T16:33:28 < dongs> 30cm
2018-11-29T16:33:33 < dongs> no worriez
2018-11-29T16:33:38 < Ecco> 30cm
2018-11-29T16:33:39 < Ecco> indeed
2018-11-29T16:33:44 < Ecco> so, WTF?
2018-11-29T16:33:59 < dongs> coat hanger that shit
2018-11-29T16:34:01 < Ecco> :-D
2018-11-29T16:34:18 < Ecco> Seriously though, are there cases where it would matter?
2018-11-29T16:34:31 < Ecco> Even if the bus is oscillating at 1GHZ
2018-11-29T16:34:46 < Ecco> that's still be 3cm for a 10% of a period error

2018-11-29T16:39:21 < jpa-> Ecco: length-matching becomes much more important when the signal is differential; if you had different lengths in differential bus, you could get e.g. 0.1 nanosecond spikes in some differential clock signal which could be long enough to trigger the receiving chip
2018-11-29T16:40:21 < jpa-> but full speed usb is pretty tolerant to that also, highspeed and superspeed less so
2018-11-29T17:07:19 < jpa-> does some debugger have handy functionality for putting a condition on call stack? for example main calling foo() which calls bar() several levels deeper, and i don't want to break when bar() is called from elsewhere? currently i do it with three breakpoints, first one automatically enabling the second one and third one disabling it, but that is tedious to set up and doesn't work with threads

2018-11-29T17:28:33 < jpa-> but even gdb doesn't seem to have anything built-in for a condition of "being called from here" (.. and besides, gdb conditional breakpoints are often too slow)

2018-11-29T18:48:17 < bitmask> so I'm redesigning my board for a pcb fab, how do you do solder mask layer?
2018-11-29T19:02:18 < aandrew> "how do you do" solder mask layer?
2018-11-29T19:02:26 < aandrew> that should be automatic based on your component footprints
2018-11-29T19:02:53 < bitmask> ahh ok
2018-11-29T19:03:21 < aandrew> what EDA package are you using?
2018-11-29T19:03:26 < bitmask> altium
2018-11-29T19:03:58 < aandrew> ok so hit 'L' to bring up the layer menu and hten shut off everything but top solder and you should see a purple rectangle around every pad
2018-11-29T19:04:02 < aandrew> also around vias by default
2018-11-29T19:04:14 < aandrew> anywhere you see purple is an area where soldermask will NOT be put
2018-11-29T19:04:19 < bitmask> ok cool thanks
2018-11-29T19:06:03 < bitmask> also what about mounting holes, does it have to be a full hole (like a pad where the drill size is equal to the ring size so its all just drilled out) or do I just need the outline of a hole on some layer
2018-11-29T19:07:09 < aandrew> depends on what you want
2018-11-29T19:07:39 < bitmask> if only I knew :P

2018-11-29T19:07:49 < aandrew> you can have plain holes, which is just a coordinate/size on the drill layer, or you can put down a pad and set the pad size to the hole size, but I am not sure why you'd want that
2018-11-29T19:08:05 < aandrew> most times unplated holes are just coordinates/sizes on the drill layer
2018-11-29T19:08:21 < bitmask> ok, drill layer it is
2018-11-29T19:08:25 < aandrew> plated holes are almost always a component with a single pad specifying the shape of the metal
2018-11-29T19:08:55 < aandrew> bitmask: you might want to check out a bunch of the free altium tutorials by fedeval. I find his accent hard to follow at some times but he knows his stuff
2018-11-29T19:08:56 < bitmask> are plated holes for grounding to the chassis?
2018-11-29T19:09:05 < aandrew> plated holes are for whatever you want them to be
2018-11-29T19:09:15 < bitmask> ok 
2018-11-29T19:09:21 < aandrew> I typically make mounting holes plated because I like having the metal around the hole for the screwhead

2018-11-29T23:26:18 < mitrax> hrm i wonder if i can rely on the temperature sensor within my mcu to get an estimate of the temperature of an external RTC crystal that's a few mm away... the cpu heat spreads to the xtal through the PCB... ambient affects the cpu as well, sounds dodgy but it's an existing design i can't change
2018-11-29T23:28:14 < Thorn> the sensor is probably very inaccurate
2018-11-29T23:29:26 < mitrax> well i don't need precision, it's +-1.5°C but it's the temp within the mcu core... 
2018-11-29T23:30:45 < englishman> time for experiment
2018-11-29T23:31:04 < mitrax> yeah that board will end up in the freezer soon...

2018-11-29T23:32:44 < englishman> yes
2018-11-29T23:32:45 < englishman> which one?
2018-11-29T23:34:25 < mitrax> an old one, neo-7M from some tarduino module,  the electronics store nearby had some, that was just for measurement purpose so i got that
2018-11-29T23:34:37 < englishman> cool
2018-11-29T23:35:19 < englishman> does that one have 10mhz output?
2018-11-29T23:35:43 < mitrax> it has an output thats configurable from 0.25Hz to 10Mhz
2018-11-29T23:35:56 < englishman> hm all the 7 series do, cool
2018-11-29T23:36:01 < englishman> they charge like 2x for that on 8

2018-11-30T11:27:02 < drzacek> Hello there
2018-11-30T11:28:18 < drzacek> What baudrates can I set on stm32? I'm using HAL functions. I've read the manual and from what I understand - every baudrate is possible, there are no "standard" and "officialy supported" values which I should take?
2018-11-30T11:29:08 < Haohmaru> wut r you connecting this to?
2018-11-30T11:30:42 < drzacek> FTDI chip -> usb -> pc
2018-11-30T11:31:22 < Haohmaru> in that case, ask yourself if the pc+ftdi would let you use "any" baudrate
2018-11-30T11:31:32 < drzacek> let's say they do
2018-11-30T11:31:51 < Haohmaru> that's a risky assumption
2018-11-30T11:31:53 < drzacek> I'm trying to rule out some potential errors here
2018-11-30T11:32:15 < drzacek> lemme rephrase - let's say they support the baudrates I want to use, for example 2000000
2018-11-30T11:32:56 < Haohmaru> let's say i agree ;P~
2018-11-30T11:33:15 < drzacek> but if I run at 2M it doesn't seem to run stabily, compared to when run at 500000
2018-11-30T11:33:39 < drzacek> software errors are of course still an option, but want to be sure that I can use that baudrate
2018-11-30T11:33:52 < Haohmaru> so wut is teh question here?
2018-11-30T11:34:24 < kakimir> 2Megs!
2018-11-30T11:34:28 < drzacek> Is 2000000 a valid baudrate for STM32f103xx running at 72mhz
2018-11-30T11:35:19 < Haohmaru> i don't know.. there should be formulas in the datasheet, and maybe a table with precomputed baudrates/settings
2018-11-30T11:35:31 < drzacek> I'm having trouble understanding that part of the manual (RM0008, page 796-797), I know there is some rounding in play which in turn means errors
2018-11-30T11:35:42 < Haohmaru> yes
2018-11-30T11:36:10 < Haohmaru> but what akchually matters is that both sides happen to be on the same rate
2018-11-30T11:37:20 < Haohmaru> you may want 2Mbit, it may happen to result in 1.995361Mbit due to this or that.. but if the other side happens to be on that same rate - ur golden
2018-11-30T11:37:49 < drzacek> any way to check the ACTUAL freq?
2018-11-30T11:38:03 < Haohmaru> sorta
2018-11-30T11:38:29 < drzacek> osciloscope?
2018-11-30T11:38:30 < Haohmaru> transmit either 0xAA or 0x55 (forgot which one)
2018-11-30T11:39:24 < Haohmaru> ..as fast as posshiburu, if the UART is set to 1start bit and 1 stop bit and nothing else fancy, then the signal should look like a square wave at half the frequency

2018-11-30T11:52:40 < drzacek> Cracki, I'm guessing those are only examples, cause you are able to set many more baudrates with fractional dividers
2018-11-30T11:52:50 < drzacek> and those what I need are not included in that table
2018-11-30T11:53:14 < drzacek> but I tried calculating that formula and it seems there is no rounding involved for 2000000 baud
2018-11-30T11:53:22 < drzacek> 72mhz clock
2018-11-30T11:54:11 < drzacek> yeah, thats the one
2018-11-30T11:55:02 < drzacek> okay
2018-11-30T11:55:14 < drzacek> so I need to look deeper down in my code for eventual problems then

2018-11-30T13:42:48 < kakimir> I use one GPIO pin to both drive the led to sequence it

2018-11-30T13:51:42 < PaulFertser> Haohmaru: stlink kinda sucks but it might work for many purposes, so worth a try.
2018-11-30T13:52:30 < PaulFertser> Haohmaru: atmel ice is cmsis-dap, right? So it should work too. As any other cmsis-dap adapter. And now you can flash sane cmsis-dap firmware to bluepill and use that.
2018-11-30T13:52:34 < Haohmaru> the chip has a few pins with names like SWDIO SWCLK TRACESWO..
2018-11-30T13:52:48 < PaulFertser> Haohmaru: so, that's just SWD.

2018-11-30T14:03:51 < PaulFertser> Haohmaru: openocd and if I'm debugging, I use "load" from gdb.
2018-11-30T14:04:30 < Haohmaru> with which device? the one you linked to on github?
2018-11-30T14:04:57 < PaulFertser> Haohmaru: with ftdi-based adapters mostly but I also use other supported interfaces occassionally. 
2018-11-30T14:05:53 < Haohmaru> oh, the ftdi-based adapter thing.. i read about it somewhere.. my impression is that it's a sort of hack
2018-11-30T14:06:17 < Haohmaru> and supposedly SWD works "faster"
2018-11-30T14:06:24 < PaulFertser> Haohmaru: plenty of expensive adapters are ftdi-based. And many vendors include on-board ftdi adapters.

2018-11-30T14:23:51 < Haohmaru> hm, the datasheet doesn't say anything about cmsis-dap
2018-11-30T14:23:52 < jpa-> ftdi chips are quite flexible, it depends a lot on the control algorithms
2018-11-30T14:24:17 < PaulFertser> Haohmaru: SWD man, it doesn't matter much what adapter you'll be using.
2018-11-30T14:24:33 < PaulFertser> Haohmaru: the datasheet doesn't say anything about jlink either. So what.
2018-11-30T14:25:02 < PaulFertser> Haohmaru: you can even use an SBC as an adapter.
2018-11-30T14:25:26 < Haohmaru> it says that it has SWD and, FPB, data watchpoint and trace, instrumentation trace macrocell, something something CoreSight, and jtag boundary scan
2018-11-30T14:26:47 < jpa-> it's pretty difficult to get used to this stuff just by reading datasheets; get some dev boards and get familiar with the tools
2018-11-30T14:27:17 < Haohmaru> yes, i'll be getting the same70-xpld board
2018-11-30T14:27:49 < Haohmaru> afaiu, it has some fancy onboard co-processor that can program the main chip via their IDE
2018-11-30T14:28:13 < zyp> what are we talking about?
2018-11-30T14:28:38 < Haohmaru> semi-off-topic sh*t :/
2018-11-30T14:28:46 < jpa-> it's not a coprocessor
2018-11-30T14:28:55 < Haohmaru> okay <something>
2018-11-30T14:28:59 < jpa-> just a plain old debugger on the same board, just like st's discovery boards etc
2018-11-30T14:29:08 < Haohmaru> *shrug*
2018-11-30T14:29:10 < jpa-> https://www.microchip.com/webdoc/protocoldocs/ch01s01.html  (EDBG in atmel's case)
2018-11-30T14:29:43 < jpa-> (and yeah, it does csmsi-dap)
2018-11-30T14:30:15 < Haohmaru> my head hurts already from so many abbreviations and fancy new words x_x
2018-11-30T14:30:30 < jpa-> you are trying to read too much ahead of time
2018-11-30T14:30:38 < jpa-> just get a board, start using it, figure out stuff as you need it
2018-11-30T14:30:52 < jpa-> it is probably easiest to start with the vendor IDE and figure out third-party debuggers and tools later
2018-11-30T14:31:15 < Haohmaru> i already began making a pcb :/
2018-11-30T14:31:26 < PaulFertser> Haohmaru: on explained board you'll have cmsis-dap integrated
2018-11-30T14:31:35 < zyp> Haohmaru, what are you making?
2018-11-30T14:31:52 < Haohmaru> re-inventing my ethernet module
2018-11-30T14:32:06 < zyp> ah, that stuff
2018-11-30T14:32:16 < zyp> sam e70 was that part with builtin phy?
2018-11-30T14:32:37 < Haohmaru> no, unfortunately, it seems built-in phy is an uber rare thing
2018-11-30T14:32:42 < Haohmaru> it only has MAC
2018-11-30T14:32:56 < zyp> yeah, on the photo of atsame70-xpld it does have a phy
2018-11-30T14:33:02 < zyp> externally
2018-11-30T14:33:09 < Haohmaru> yes, the ksz8081rna
2018-11-30T14:33:30 < zyp> any reason in particular you went with atsam?
2018-11-30T14:33:44 < Haohmaru> i'm trying to copy/paste from the xpld board as much as possible, however, the xpld board uses the 144pin chip, while i'm using the 64pin variant
2018-11-30T14:33:53 < zyp> ah, 64pin, got it
2018-11-30T14:35:42 < Haohmaru> i generated <some> codez with atmel.start, and i downloaded an example firmware for the xpld board that shows an ethernet bootloader, so i'll be trying to butcher something together with duct tape x_x
2018-11-30T14:37:03 < zyp> so anyway, is this supposed to be an ethernet module that only runs networking, and interfaces to another mcu for the main system?
2018-11-30T14:37:17 < Haohmaru> yes
2018-11-30T14:37:47 < zyp> and none of the existing ethernet modules on the market fits the bill?
2018-11-30T14:38:53 < Haohmaru> not exactly
2018-11-30T14:39:35 < Haohmaru> wiznet had one that was close
2018-11-30T14:39:49 < Haohmaru> but it had an unelegant config tool
2018-11-30T14:39:55 < Haohmaru> (as if mine is elegant)
2018-11-30T14:41:16 < zyp> hmm
2018-11-30T14:41:57 < Haohmaru> and most of them are async UART or something similar
2018-11-30T14:42:05  * Haohmaru hides
2018-11-30T14:42:35 < Haohmaru> so anything with "SWD cmsis-DAP" will work?
2018-11-30T14:42:40 < zyp> what do you need?
2018-11-30T14:43:03 < Haohmaru> at least a programmer, and it'd be gud if the connector doesn't have to be huge
2018-11-30T14:43:33 < Haohmaru> the xpld board has the SWD thing on a 20pin 2.54mm connector x_x
2018-11-30T14:43:34 < zyp> I meant the interface
2018-11-30T14:44:15 < Haohmaru> synchronous USART slave is what i use on the "old" eth module right now, and it works fine
2018-11-30T14:44:51 < zyp> oh, is that why you've been going on about synchronous?
2018-11-30T14:45:03 < Haohmaru> yez
2018-11-30T14:46:45 < zyp> I think the reason synchronous isn't well supported is because nobody cares about synchronous :p
2018-11-30T14:47:03 < zyp> modern uarts can keep up perfectly well without external clock :p
2018-11-30T14:47:33 < zyp> and then there's SPI if you need something faster
2018-11-30T14:48:07 < Haohmaru> or USART, with an emphasis on the S
2018-11-30T14:48:54 < Haohmaru> some vendors seem to not have a proper USART periph
2018-11-30T14:49:32 < Haohmaru> i was thinking to use USART once on a pic18 iirc, and i don't remember what happened but i think there was no actual clock pin or something dumb like that
2018-11-30T14:57:36 < Haohmaru> or maybe i should just get the atmel ice?
2018-11-30T14:57:49 < Haohmaru> it will be able to debug my xmegas afaik
2018-11-30T14:57:54 < Haohmaru> that'd be fancy

2018-11-30T15:49:25 < bitmask> is there any problem crossing logic lines on opposite sides of a board?
2018-11-30T15:50:06 < bitmask> I'm guessing if thats an issue it would be for analog stuff at high power?
2018-11-30T15:50:23 < jpa-> yeah, you'll be breaking up your ground plane and should arrange for ground return path as a signal instead
2018-11-30T15:50:59 < jpa-> you can probably get away with it if there is no sensitive analog stuff on same board and speed is not very high etc.
2018-11-30T15:51:03 < bitmask> I'm not using the whole board as a ground plane

2018-11-30T15:51:21 < bitmask> since only a few things need a path there
2018-11-30T15:51:29 < zyp> jpa-, what?
2018-11-30T15:51:29 < bitmask> and theres two voltages on the board
2018-11-30T15:51:33 < jpa-> ok, well then you have nothing to lose :P
2018-11-30T15:51:58 < bitmask> its not very sensitive stuff, I think I'll be ok
2018-11-30T15:52:12 < zyp> jpa-, on 2L, crossing tracks on opposite sides is exactly what you want to do
2018-11-30T15:52:26 < bitmask> oh one thing though, can you route a trace from a pad to a plane? doesnt seem to want to do that in altium
2018-11-30T15:52:35 < zyp> what you want to avoid is running parallel tracks on both sides
2018-11-30T15:52:45 < bitmask> oh really? 
2018-11-30T15:52:46 < jpa-> well, it's the only thing you can do on 2L; but you should think about ground return paths for each of the signals
2018-11-30T15:52:55 < zyp> yes
2018-11-30T15:53:07 < jpa-> zyp: do you avoid running tracks parallel on same side? what more reason is there to avoid it on opposite sides?
2018-11-30T15:53:13 < bitmask> this is a very basic board, its basically an arduino nano shield
2018-11-30T15:53:37 < jpa-> (ok, i guess parallel tracks also break ground pretty well)
2018-11-30T15:53:48 < bitmask> I would make my own 'nano' (atmega328P) board as I have some ICs for it but I dont really trust myself soldering them at this point
2018-11-30T15:54:00 < zyp> jpa-, on 2L boards, the ground plane is made up of ground pours on both sides stitched together
2018-11-30T15:54:02 < jpa-> usually on 2L boards i avoid running signals on the other side except for short hops
2018-11-30T15:54:20 < zyp> tracks running in parallel on both sides creates long cuts
2018-11-30T15:54:51 < jpa-> zyp: but if all signals run parallel to the long cut, the long cut doesn't matter?

2018-11-30T15:57:48 < zyp> I'd route everything in the same layer
2018-11-30T15:58:10 < bitmask> why does it matter in this case?
2018-11-30T15:58:19 < zyp> if you're not using pins 17/18, you can run the signals for 23-24 in between there to avoid the conflict with 19-22
2018-11-30T15:58:27 < zyp> well
2018-11-30T15:58:34 < jpa-> it doesn't really matter for such stuff, you are not going to get it EMC tested anyway :P
2018-11-30T15:58:44 < bitmask> right :)
2018-11-30T15:58:45 < zyp> on a design of that complexity where you're using a DIP breakout, shit doesn't matter at all
2018-11-30T15:59:30 < zyp> but you're the one asking how to do it right :p
2018-11-30T15:59:52 < bitmask> this is the second board although I corrected the weird angle to the two pin connector in the center: https://i.imgur.com/dFg0Ykc.png
2018-11-30T16:00:11 < bitmask> zyp true
2018-11-30T16:00:20 < jpa-> why so thin traces?
2018-11-30T16:00:37 < bitmask> they are 10 mil, isn't that normal?
2018-11-30T16:00:45 < zyp> 10 mil is pretty thick :p
2018-11-30T16:00:50 < bitmask> I thought so
2018-11-30T16:00:57 < jpa-> hmm, i guess i didn't just realize the scale of the board :P
2018-11-30T16:01:30 < bitmask> its weird how it shows it because theres a 15 mil route that looks the same width, should it appear differently?
2018-11-30T16:01:31 < zyp> they just look thin because everything are huge pth parts with a couple millimeters of pitch :p
2018-11-30T16:01:38 < bitmask> is there anyway to check the gerber?
2018-11-30T16:01:50 < zyp> just zoom in and see?
2018-11-30T16:02:02 < jpa-> bitmask: the board is so big that 15 mil or 10 mil is just 1 pixel anyway in the small image
2018-11-30T16:02:04 < bitmask> oh yea I guess a gerber viewer would do it :P
2018-11-30T16:02:41 < zyp> on the other hand, with pth pads like that, you might want to do thicker traces just for mechanical strength
2018-11-30T16:02:53 < zyp> thinner traces are easier to fuck up when you're soldering
2018-11-30T16:03:33 < Haohmaru> or ask for that extra thicc soldermask
2018-11-30T16:03:45 < bitmask> I think if I go any bigger I'd have to route it differently, I'll try it as it is
2018-11-30T16:03:56 < zyp> uh
2018-11-30T16:04:14 < zyp> judging by the pic you have way more clearance than trace there
2018-11-30T16:04:27 < zyp> and minimums for each are usually on the order of 6/6
2018-11-30T16:04:28 < bitmask> oh right, I can lower the clearance
2018-11-30T16:04:37 < jpa-> back when i used to ocd about pcbs, i'd up the global thickness until i started getting DRC errors
2018-11-30T16:05:36 < zyp> when I'm doing a 6/6 board, I usually set the minimums in the rules to 6 and route with 8mil traces
2018-11-30T16:06:47 < zyp> gives me a bit to go on when I need to squeeze in something that almost fits with 8 mil :p
2018-11-30T16:07:36 < zyp> https://bin.jvnv.net/file/Q8moB.png <- like the trace that passes between those capacitor pads
2018-11-30T16:08:00 < zyp> IIRC everything else is 8 mil, but the segment under the capacitors is lowered to 7 :p

2018-11-30T17:11:22 < zyp> range on a charge is of course a lot better, but charging wise it sounds like my car performs better
2018-11-30T17:12:24 < englishman> id avoid leaf until they switch away from those awful jap batteries
2018-11-30T17:13:06 < englishman> leaf is literally the only car where "battery degredation" is so bad they have a battery health meter right on the dash 24/7
2018-11-30T17:13:31 < zyp> haha, I've never understood that
2018-11-30T17:13:40 < mawk> get your screwdriver and swap the battery

2018-11-30T17:17:46 < englishman> then again, the amount i paid for the whole leaf is the same as 2-3 years of new egolf depreciation

2018-11-30T17:36:08 < zyp> if you're not making a ground plane in one layer, there's no point in trying to put all the signals in the other layer
2018-11-30T17:36:47 < bitmask> I get what you mean
2018-11-30T17:37:33 < zyp> also, the way you have divided your design into multiple grounds looks fucked up
2018-11-30T17:38:01 < zyp> I assume the buck in/buck out ports will be hooked to the same shit and have their grounds tied together?
2018-11-30T17:38:04 < bitmask> can you use the same ground for two voltages?
2018-11-30T17:38:24 < bitmask> if so then it makes more sense to keep the bottom an actual ground plane
2018-11-30T17:39:16 < bitmask> if not then what else could I do
2018-11-30T17:39:18 < zyp> depends on your supplies, but having one ground and all voltage rails being relative to it is normal
2018-11-30T17:39:44 < bitmask> I have 12v coming in and then going out to a buck converter to get 5v
2018-11-30T17:40:26 < zyp> I assume the transistor is a n-channel mosfet?
2018-11-30T17:40:30 < bitmask> yes
2018-11-30T17:41:36 < zyp> how do you suppose that's gonna work in that design? which ground is gate voltage relative to? which ground is source voltage relative to? which Vgs do you end up with?
2018-11-30T17:42:58 < zyp> if you want to treat the 12V domain as galvanically separate from the 5V domain, you have to actually add galvanic separation on signals crossing between the domains
2018-11-30T17:43:00 < bitmask> oh I guess I do have gate pulled down to the 12v supply
2018-11-30T17:44:10 < bitmask> I don't know if I care if they are separate?
2018-11-30T17:44:24 < bitmask> I just didnt think I could combine ground planes, that would make things easier though?
2018-11-30T17:44:39 < zyp> if you don't need them to be separate, you don't want them to be separate
2018-11-30T17:45:00 < bitmask> ok cool, that simplifies shit
2018-11-30T17:45:04 < bitmask> I'll just make the bottom a common ground plane then
2018-11-30T17:45:11 < zyp> galvanic isolation adds cost and complexity to a project, you only add it when you need to
2018-11-30T17:45:27 < bitmask> I dont know when you'd need it so I really doubt I do
2018-11-30T17:46:12 < zyp> https://bin.jvnv.net/file/CjtC8.png <- you need it in a design like this
2018-11-30T17:47:15 < bitmask> that means nothing to me, you think I have any idea what I'm doing? :P
2018-11-30T17:47:48 < zyp> the upper half has its ground plane hooked to PE, i.e. actual ground, this is required so that stuff like usb connectors are safe to touch
2018-11-30T17:48:04 < bitmask> ahh
2018-11-30T17:48:55 < zyp> the lower half is an energy metering circuit that is measuring voltages and stuff on live power lines, so it has its ground plane hooked to the N line
2018-11-30T17:49:07 < zyp> because all measurements are taken relative to N
2018-11-30T17:49:29 < sync> or you deal with audio shit and want to avoid ground loops
2018-11-30T17:50:03 < zyp> depending on how this gets hooked up, the difference between N and PE might differ by 0V, 135V or 230V, and for this reason they need to be kept isolated
2018-11-30T17:50:29 < zyp> and even in the 0V case, it's not okay to leak current between N and PE
2018-11-30T17:50:52 < zyp> for situations like this, it matters
2018-11-30T17:51:17 < Haohmaru> hm, so gdb "talks" to openocd via TCP? and openocd itself deals with the actual chip thru the debugger?
2018-11-30T17:54:50 < Haohmaru> ah
2018-11-30T17:55:45 < Haohmaru> so openocd makes two TCP servers, one for commands that let you flash/erase yer chip, and another one for gdb which can be used by the IDE
2018-11-30T17:55:46 < Haohmaru> noice
2018-11-30T17:56:13 < Haohmaru> so i might even be able to debug with CodeBlockz
2018-11-30T17:56:26 < Haohmaru> that'd be kewl
2018-11-30T17:56:58 < Haohmaru> but openocd would require that i feed some "configuration" that tells it details about my chip?
2018-11-30T17:59:20 < Haohmaru> hm
2018-11-30T18:00:38 < Haohmaru> so i'd better go with the atmel-ice then?
2018-11-30T18:02:46 < Haohmaru> ahumz, so supposedly a jlink thing is uber cheap?
2018-11-30T18:03:41 < Haohmaru> i installed atmel studio, but tbh i don't wanna use it.. it looks uglier than my C::B setup
2018-11-30T18:04:26 < Haohmaru> now now
2018-11-30T18:04:36  * Haohmaru == nobody
2018-11-30T18:04:53 < Haohmaru> what will i gain?
2018-11-30T18:05:16 < Haohmaru> isn't eclipse that thing written in java?
2018-11-30T18:05:43 < Haohmaru> i am fairly comfortable with C::B
2018-11-30T18:06:19 < Haohmaru> just highly ineggsperienced with arm and mcu debuggers and sh*t
2018-11-30T18:08:06 < Haohmaru> i configured my sh*t and i'm building the atmel.start project without makefiles and sh*t
2018-11-30T18:08:15 < Hamilton> Yeah I was using Code:Blocks for some times then I moved to Eclipse...It's actually not bad...I blame my loltop for hiccups and slowness of Eclispe
2018-11-30T18:08:28 < Hamilton> Now I'm in try-hard vim mode
2018-11-30T18:08:50 < fenugrec> but ed is the standard editor.
2018-11-30T18:10:05 < Haohmaru> Cracki my point was, i can set up C::B to build a given pile of code, it's not like highly impossible
2018-11-30T18:10:35 < Hamilton> Haohmaru, And you are ignoring eclipse because it's java-based?
2018-11-30T18:10:44 < Haohmaru> and C::B is now big and slow like atmel studio or some of the other horrors i've tried
2018-11-30T18:10:56 < Haohmaru> * is NOT big..
2018-11-30T18:12:00 < Hamilton> Anyway, I watched Bustler Scrugz...that was actually very good
2018-11-30T18:13:30 < Haohmaru> it's not a problem for now.. if i get stuck with C::B i'll try with teh nasty AS sh*t
2018-11-30T18:13:39 < Haohmaru> (but i doubt)
2018-11-30T18:15:02 < PaulFertser> Haohmaru: consider Emacs ;)
2018-11-30T18:15:38 < Haohmaru> is that the one where you can't even close it down with ctrl+c/ctrl+x ?
2018-11-30T18:17:06 < PaulFertser> Haohmaru: C-x C-c closes it though.
2018-11-30T18:17:15 < Haohmaru> isn't it like a terminal-based notepad.exe
2018-11-30T18:17:34 < Haohmaru> i want something that has a nice thicc "build" button ;P~
2018-11-30T18:17:36  * Haohmaru hides
2018-11-30T18:17:38 < fenugrec> can we have an old-fashioned editor flamewar ?

2018-11-30T18:27:05 < Haohmaru> can i use it at teh office?
2018-11-30T18:29:14 < Hamilton> guess you can't use it to develop a device which is gonna be sold but am not a lawyer 
2018-11-30T18:29:28 < PaulFertser> Haohmaru: the jlink owner seems to be a nice guy. He just kindly asks you to not use it for professional job. It's ok for EDU to be used for hobby purposes. Probably developing OSHW is ok too, not sure. If you have a real business then why not pay him the money he deserved?
2018-11-30T18:29:39 < Hamilton> I also don't know how could they detect whether a device was programmed with edu or non-edu flasher
2018-11-30T18:30:06 < Haohmaru> PaulFertser oh, okay then
2018-11-30T18:30:27 < Haohmaru> well, then "EDU" is not for me
2018-11-30T18:30:48 < PaulFertser> Haohmaru: if you're getting an xplained board anyway why do you need another adapter?
2018-11-30T18:30:49 < Haohmaru> holy crap, does that make me a "pro" ? o_O
2018-11-30T18:31:20 < Haohmaru> PaulFertser i'm already working on the PCB for the eth module i'm trying to make
2018-11-30T18:31:25 < Hamilton> but PaulFertser does the programmer/flasher add a sign about licence to the device being programmed?
2018-11-30T18:31:41 < PaulFertser> Hamilton: no
2018-11-30T18:31:51 < Hamilton> PaulFertser, then how can they enforce it?
2018-11-30T18:32:01 < PaulFertser> Hamilton: by kindly asking
2018-11-30T18:32:11 < Hamilton> :)
2018-11-30T18:32:32 < Haohmaru> i probably won't be playing too much with the xplained board (assuming the pcb i make doesn't blow up)
2018-11-30T18:33:02 < PaulFertser> Haohmaru: I mean you can use xplained board's debugger to debug your own board.
2018-11-30T18:33:09 < Haohmaru> can i?
2018-11-30T18:33:39 < Haohmaru> oh, there were some 0ohm resistors in the schematic
2018-11-30T18:33:52 < Haohmaru> i'll check that out again then
2018-11-30T18:35:08 < PaulFertser> Haohmaru: also, can't you get a couple of "blue pill" boards so that you have stm32 handy for various projects, and use one of them as an swd adapter?
2018-11-30T18:36:03 < PaulFertser> "The SAM D20 Xplained Pro features a Cortex® Debug Connector (10-pin) for programming and debugging an external target."
2018-11-30T18:36:59 < Haohmaru> i could get many things, if that would help
2018-11-30T18:37:00 < bitmask> if the only difference I have in choosing gnd/power plane sides is that I have two smd components that connect to gnd, is it ok to put the gnd plane on top so that I don't need to add vias?
2018-11-30T18:38:13 < Haohmaru> the same70-xpld has a 20pin jtag connector which actually only has SWD on it, and there was another unpopulated connector about some "Trace" thing
2018-11-30T18:46:45 < Haohmaru> hm.. i'm not so sure now.. there's an AT32UC3A4256J chip there, but i think there doesn't seem to be a way to use it alone..
2018-11-30T18:48:16 < PaulFertser> Haohmaru: bluepill costs like a buck or so.

2018-11-30T19:10:30 < Laurenceb> met CE standards bro

2018-11-30T19:10:58 < Laurenceb> oh that
2018-11-30T19:11:17 < zyp> as far as I can remember, it was pretty good at picking up noise
2018-11-30T19:11:39 < zyp> and had pretty shitty ground plane design
2018-11-30T19:11:43 < Laurenceb> oh that was the Honeywell magnos
2018-11-30T19:11:58 < Laurenceb> they spit out real nasty spikes
2018-11-30T19:12:06 < Laurenceb> and there was a 24bit adc nearby
