2022-01-01T00:00:01 < zyp> lots of air inside it really
2022-01-01T00:00:53 < zyp> the nice part is that it came with full documentation, including all the pinouts between the main cpu and the power electronics
2022-01-01T00:02:46 < zyp> so I'm planning to make a drop in replacement board that reads the encoder signals and generates six channels worth of three phase pwm, presenting it all as six servo drives over some industrial ethernet interface
2022-01-01T00:03:36 < srk> cool
2022-01-01T00:03:47 < srk> CoE .. CANOpen over EtherCAT :D
2022-01-01T00:04:01 < veverak> I've been stuck in academic article for robots for a while
2022-01-01T00:04:07 < veverak> *articles
2022-01-01T00:04:19 < zyp> I like the low latency stuff ethercat does, but instead of getting ahold of the spec and implementing something conforming to it, I think I'll just hack up my own similar-ish protocol
2022-01-01T00:04:50 < PaulFertser> zyp: how come the documentation is available?
2022-01-01T00:04:51 < srk> I see it as just a transport layer, would use CANOpen as app layer
2022-01-01T00:05:00 < veverak> what stuck me as interesting is ... they run 1kHz control loops over ethercat that makes the thing quite ... "complex" (as it requries ethercat just to walk) 
2022-01-01T00:05:07 < veverak> and all they send is just torques required
2022-01-01T00:05:34 < veverak> seems to me that less BW over the buss would be required if the communication protocol would use more high level commands and the drivers in contact with motors were smarter
2022-01-01T00:05:59 < PaulFertser> srk: isn't canopen kinda over-engineered?
2022-01-01T00:06:10 < zyp> PaulFertser, https://bin.jvnv.net/file/KqaOV.jpg
2022-01-01T00:06:34 < zyp> I implemented EPL in my previous job, which is canopen over poll/response ethernet
2022-01-01T00:06:35 < srk> veverak: that's pretty much interpolated position 
2022-01-01T00:06:47 < zyp> i.e. similar to CoE, but less fancy
2022-01-01T00:06:57 < veverak> srk: yup, they tend to use known curves (not even something special, but normal stuff like bezier)
2022-01-01T00:07:00 < zyp> and I don't really want to dick more around with canopen :)
2022-01-01T00:07:11 < veverak> so why don't just send driver something like "make a bezier fucker"
2022-01-01T00:07:29 < srk> you send control points for some curve
2022-01-01T00:07:34 < veverak> (ok, bezier is done with the leg, so the torque on motors has different curve)
2022-01-01T00:07:56 < PaulFertser> zyp: nice box there, and funny welding picture too
2022-01-01T00:08:18 < srk> if you need torque/pos/velocity you increase polynomial degree
2022-01-01T00:08:46 < srk> that's pretty much it. spec is freeform so you can do 5th order polynomials or more iff needed
2022-01-01T00:09:04 < veverak> you talk about opencan?
2022-01-01T00:09:15 < Laurenceb> n00b question: is it usually possible to write to JFFS filesystems on embedded Lunix?
2022-01-01T00:09:24 < zyp> srk, the thing that does my head in is that the kinematics is nonlinear :)
2022-01-01T00:09:31 < Laurenceb> I want to put scripts onto a rooted cheap IP camera
2022-01-01T00:09:43 < zyp> or rather, that the *inverse* kinematics are nonlinear
2022-01-01T00:09:46 < srk> veverak: interpolated position is part of canopen but the concept is similar everywhere
2022-01-01T00:10:04 < veverak> srk: hmm, interesting
2022-01-01T00:10:23 < veverak> I am pretty sure the articles just send torque targets at 1kHz and that's it
2022-01-01T00:10:37 < srk> depends on use case ofc
2022-01-01T00:11:09 < veverak> zyp: inverse IK is nonlinear, but these days in legged robots inverse dynamics is the shit, which is not better anyway :)
2022-01-01T00:11:18 < PaulFertser> Laurenceb: usually you can write to any non-ro filesystem on Linux.
2022-01-01T00:11:24 < veverak> and you do IK -> ID chain anyway, so tough luck
2022-01-01T00:11:43 < PaulFertser> Laurenceb: JFFS2 is pretty common but JFFS is probably something ancient?
2022-01-01T00:12:01 < veverak> still "updating desired torque at 800khz to all joints" seems like .. hmm, way that makes me feel "we can do better"
2022-01-01T00:12:06 < zyp> these days you get commodity fpga modules with dual gigabit PHYs, so I was thinking to design my ethercat-ish protocol to run on these: https://www.aliexpress.com/item/1005001686186007.html
2022-01-01T00:12:49 < srk> you'll end up with yaskawa grade hardware that runs fibre optics or something like that :D
2022-01-01T00:13:14 < zyp> I was thinking PoE actually
2022-01-01T00:13:29 < zyp> for like signal lights and shit
2022-01-01T00:14:34 < zyp> when the fpga modules are $30, why not just put one in everything and stick everything on the bus
2022-01-01T00:14:48 < srk> :D 
2022-01-01T00:14:51 < srk> fpga shortage next
2022-01-01T00:14:53 < veverak> anyway, point of having custom board for servomotor is to move the "IK/ID" computations to the servomotors directly -> I can send high level commands -> less BW needed
2022-01-01T00:15:02 < zyp> nah
2022-01-01T00:15:11 < veverak> -> shit can be cheap \o/
2022-01-01T00:15:35 < zyp> these modules are designed for video walls, hence fpga and dual ethernet for daisy chaining
2022-01-01T00:15:50 < zyp> and also means they already have a mass market, so they are cheap off the shelf
2022-01-01T00:15:54 < srk> PaulFertser: I don't think it is overengineered, the core is pretty simple. mostly remote registers 
2022-01-01T00:16:02 < srk> PaulFertser: hny!
2022-01-01T00:16:45 < zyp> a single large video wall can contain like a hundred of those modules
2022-01-01T00:17:09 < srk> oh thanks for reminding me of that chinese ecp5 board
2022-01-01T00:17:16 < zyp> yes
2022-01-01T00:17:26 < zyp> this is a newer variant of the one that was all the rage last year
2022-01-01T00:17:34 < srk> remember I wanted to get one
2022-01-01T00:17:35 < PaulFertser> srk: hm, what about the state machine that plays a role on startup, then all the PDOs and object dictionary that can be reconfigured on runtime etc?
2022-01-01T00:18:30 < zyp> the old one was kinda annoying since it had fixed output buffers on all connected IOs, but this one is a module just containing the PHYs
2022-01-01T00:18:52 < zyp> so you just stick it on a board, hook up a pair of magjacks and feed it 5V
2022-01-01T00:18:59 < srk> PaulFertser: configurable PDOs are optional, state machines makes sense tho
2022-01-01T00:19:22 < srk> PaulFertser: I've checked couple of commercial products and often there's no configurable PDOs 
2022-01-01T00:19:32 < srk> just hard-wired ones 
2022-01-01T00:19:53 < srk> realized that *after* I've mostly implemented the configurable ones :((
2022-01-01T00:20:06 < zyp> haha
2022-01-01T00:20:31 < zyp> in the EPL stuff I worked on, I were the master, so I just hardcoded all the PDO layouts
2022-01-01T00:20:40 < PaulFertser> srk: well, reading the official standard papers, including the one to assign dynamic addresses :/
2022-01-01T00:21:08 < zyp> but I had to implement the whole mechanism for configuring the PDO mapping of an off the shelf EPL gateway
2022-01-01T00:23:03 < srk> fun :)
2022-01-01T00:24:02 < srk> master running on stm32?
2022-01-01T00:24:05 < zyp> nah, screw that, I'm gonna roll my own protocol this time
2022-01-01T00:24:11 < zyp> nope
2022-01-01T00:24:21 < zyp> all our devices used TI RM4
2022-01-01T00:24:54 < zyp> all as in both the master and slaves
2022-01-01T00:25:05 < srk> ah, cool, and custom code or some lib?
2022-01-01T00:25:17 < zyp> custom
2022-01-01T00:25:43 < srk> I've only used python canopen as a master since I don't have haskell one yet :D
2022-01-01T00:26:34 < zyp> my EPL implementation is pretty thin since the only proper EPL device on the bus was the gateway
2022-01-01T00:27:06 < zyp> full of hardcoded assumptions :)
2022-01-01T00:27:33 < zyp> but EPL is pretty shit, don't use that :)
2022-01-01T00:28:48 < zyp> at design time we opted for EPL because it works with regular MACs, so you don't need special chips…
2022-01-01T00:28:51 < veverak> <rant> god damnt it, sometimes I feel like overengineer with the robots, and sometimes the articles are like: "we have this quadruped robot that uses three Intel NUC so it is able to compute it all"
2022-01-01T00:29:01 < veverak> "and we run 800khz control loop on one of them" </rant>
2022-01-01T00:29:08 < zyp> except for latency it relies on repeaters instead of switches
2022-01-01T00:29:09 < PaulFertser> srk: I had an impression CanOpen was a result of some "standards comittee", feels kind of unfocused and way too broad.
2022-01-01T00:29:21 < zyp> and repeater chips doesn't exist :)
2022-01-01T00:29:24 < veverak> what is the control loop doing? written in javascript doing 3d math?
2022-01-01T00:29:47 < zyp> the only repeater chip I'm aware of is some microchip switch chip with a repeater mode
2022-01-01T00:29:55 < zyp> and it fucking doesn't work when put into repeater mode
2022-01-01T00:30:34 < zyp> so in practice you'll end up with a FPGA or something to implement a repeater anyway
2022-01-01T00:30:53 < qyx> oh zyp is a switch pro now
2022-01-01T00:31:00 < zyp> haha, idk
2022-01-01T00:31:11 < qyx> I need 2x sgmii + 1x copper MDI
2022-01-01T00:31:31 < zyp> two SGMII? not sure I've seen that
2022-01-01T00:31:43 -!- hiovoltage [~hiovoltag@176.88.83.200] has joined ##stm32
2022-01-01T00:31:52 < qyx> two for two sfp
2022-01-01T00:32:10 < qyx> idk if fpga is the way
2022-01-01T00:32:31 < catphish> qyx: what are you building wiht gigabit ethernet?
2022-01-01T00:32:35 < Steffanx> So positive or negative bitmask ?
2022-01-01T00:32:52 < bitmask> i think pos
2022-01-01T00:33:15 < qyx> catphish: nothing yet, thinking about backplane extenders for my pcie-like boards
2022-01-01T00:33:16 < zyp> qyx, just need a dumb switch?
2022-01-01T00:33:32 < qyx> hopefully yes
2022-01-01T00:33:52 < qyx> VLANs would be good though
2022-01-01T00:35:32 < fenugrec> heh, canopen, played with a few stacks and there was no way it was going to fit in an F042. Ended up writing a barely-compliant, barebones stack... 
2022-01-01T00:35:38 < zyp> hmm, all the KSZ stuff is either dual RGMII or one RGMII and one SGMII, no dual SGMII
2022-01-01T00:35:55 < srk> PaulFertser: exactly. also pretty boring :D 
2022-01-01T00:36:00 < zyp> maybe there's a lowend VSC that fits
2022-01-01T00:36:03 < qyx> all ksz stuff is ujnabailable now
2022-01-01T00:36:40 < fenugrec> SDOs are not simple but it's nice to not invent a segmented protocol for transferring > 8bytes
2022-01-01T00:36:50 < qyx> hm there was some TI IC to convert rgmii to sgmii
2022-01-01T00:36:54 < PaulFertser> fenugrec: oh, I had the privilege to use CanFestival, guess I should be feeling lucky.
2022-01-01T00:37:08 < srk> PaulFertser: but if you reinvent you end up with similar complexity. you can completely ignore the profiles and state machines tho and make your own if you don't aim for compliance
2022-01-01T00:37:41 < fenugrec> PaulFertser, well, you missed out on a whole truckload of boilerplate , so yes, definitely luckier than others P )
2022-01-01T00:37:58 < fenugrec> (that aliexpr fpga board has an "Etrontech' IC... always an amusing brand name"

2022-01-01T00:40:58 < qyx> imterestimg
2022-01-01T00:41:00 < srk> fenugrec: what you did with canopen?
2022-01-01T00:41:28 < zyp> gotta love that dual row qfn172 though :)
2022-01-01T00:41:56 < srk> hah, lovely package
2022-01-01T00:42:15 < zyp> and it's probably unobtanium anyway
2022-01-01T00:42:29 < fenugrec> srk, working on a BMS
2022-01-01T00:42:48 < srk> cool!
2022-01-01T00:43:32 < fenugrec> Lely had a canopen stack that looked really promising, but yeah, no way that was going to fit in 32k flash
2022-01-01T00:44:10 < srk> I haven't tried mine on anything smaller than f4. probably wouldn't fit
2022-01-01T00:46:04 < fenugrec> your own stack ??
2022-01-01T00:46:07 < srk> I'm reconsidering STs atm, might try fpgas with risc-v core instead
2022-01-01T00:46:57 < qyx> would it fit inside a lowend fpga?
2022-01-01T00:47:17 < fenugrec> can you even fit riscv on a lowend fpga ?
2022-01-01T00:47:21 < zyp> what's your definition of lowend fpga?
2022-01-01T00:47:24 < fenugrec> heh
2022-01-01T00:47:25 < zyp> fenugrec, yes
2022-01-01T00:47:47 < zyp> fenugrec, https://github.com/olofk/serv
2022-01-01T00:48:24 < srk> yep
2022-01-01T00:48:58 < zyp> vexriscv fits in the largest ice40s
2022-01-01T00:49:05 < srk> I'm running one on ice40up5. "just" needs a way to flash and run code from 2nd flash
2022-01-01T00:49:18 < zyp> and the smallest ecp5s are still fairly lowend really
2022-01-01T00:49:35 < zyp> srk, why second flash?
2022-01-01T00:49:41 < srk> fenugrec: yeah, but it is very obscure (haskell that generates C) :) https://github.com/distrap/ivory-tower-canopen 
2022-01-01T00:50:06 < srk> zyp: I have this veldt board https://www.standardsemiconductor.com/ 
2022-01-01T00:50:28 < srk> zyp: you flash fpga fw to one flash and there's a spare one for risc-v fw
2022-01-01T00:50:34 < zyp> ah
2022-01-01T00:51:49 < srk> new to this so I'm not quite sure how to do that yet. like excercise for a reader
2022-01-01T00:52:42 < srk> currently it runs this on startup https://github.com/standardsemiconductor/lion/blob/main/lion-soc/bios/bios.S .. prints a welcome message and checks JEDEC ID of the flash
2022-01-01T00:52:49 < fenugrec> srk I thought you were writing a canopen stack. Was going to say "please not another one"
2022-01-01T00:53:23 < srk> :D mine is especially obscure, no worries
2022-01-01T00:53:28 < fenugrec> haskell... figures
2022-01-01T00:53:39 < fenugrec> the stockholm syndrome of programming languages, amirite
2022-01-01T00:53:50 < srk> clash is like migen but with less python
2022-01-01T00:54:08 < srk> https://clash-lang.org :D
2022-01-01T00:57:42 < srk> fenugrec: worst thing about haskell is that it embeds other languages easily and it's a common idiom.. you build an embedded language in haskell that solves your problem domain first and the proceed with the task at hand
2022-01-01T00:58:49 < srk> it's like one language to rule them all because it has enough power and expressiveness to embed bunch of other languages
2022-01-01T00:59:25 < srk> we have tons of generators to not have to bother with low level tools
2022-01-01T00:59:31 < srk> boom!
2022-01-01T00:59:35 < srk> hny
2022-01-01T00:59:52 < srk> hope it sucks less than 2021 and 2020
2022-01-01T01:01:01 < fenugrec> happy gregorian calendar rollover

2022-01-01T12:20:55 < Steffanx> Merci monsieur Xogium, tu aussi. 
2022-01-01T12:21:02 < Steffanx> Lol my French 😅
2022-01-01T12:22:44 < Xogium> Steffanx: hey, wasn't that bad
2022-01-01T12:22:53 < Xogium> you only got one word wrong
2022-01-01T12:28:17 < Steffanx> Hah
2022-01-01T12:28:47 < Xogium> can you guess which one ? :D
2022-01-01T12:31:55 < Steffanx> Xogium: no clue. 
2022-01-01T12:32:36 < Xogium> it was the tu ;)
2022-01-01T12:33:43 < Xogium> don't think english has a concept of this… You have a word for me, but not to designate something that is for another person
2022-01-01T12:34:15 < Xogium> in french there's moi for me, toi for… I don't know but its equivalent of me but second person singular
2022-01-01T12:34:50 < Xogium> in english there's just you, I think
2022-01-01T13:26:59 < sauce> it's just a possessive, your
2022-01-01T13:52:13 < Steffanx> Xogium: so "vous aussi" it should be? (according to Google translate)
2022-01-01T13:58:11 < Xogium> Steffanx: depends if you talk of multiple people, or if you want to be informal
2022-01-01T13:58:14 < Xogium> er, formal
2022-01-01T13:59:35 < Steffanx> OK english it is then
2022-01-01T14:00:02 < Xogium> yeah french is just confusing as hell like this… :p
2022-01-01T14:04:02 < Steffanx> Xogium: anyway, now I'm still not sure what it should have been 
2022-01-01T14:04:38 < Xogium> Steffanx: should have been, toi. If you want to make it informal because you're familiar with the person

2022-01-01T15:44:12 < Steffanx> Aah
2022-01-01T15:45:29 < Xogium> but its weird like that in french, if you want formal you use vous, at least in that context
2022-01-01T15:45:45 < Xogium> which… doesn't make much sense but then again, who said french made any sort of sense ?
2022-01-01T15:55:15 < qyx> so you=toi is for single person, informal
2022-01-01T15:55:28 < qyx> and you=vous for multiple persons or single person formal
2022-01-01T15:56:03 < Xogium> qyx: yeah
2022-01-01T15:56:19 < qyx> makes perfect sense :P
2022-01-01T15:56:21 < qyx> same in .sk
2022-01-01T15:56:52 < Xogium> same for tu, but then again its like I said we have difference between pronouns and between words like me and you'd use for you
2022-01-01T15:58:40 < Xogium> but beyond that its so weird as a language
2022-01-01T15:58:54 < Xogium> it isn't very logical in some things
2022-01-01T15:59:19 < Xogium> like you take e, a and u, and you pronounce it 'o'
2022-01-01T15:59:58 < Xogium> that's water by the way ;)

2022-01-01T17:09:41 < Xogium> I wish it wasn't like that but honestly, it feels like it more and more

2022-01-01T17:34:41 < jadew> thought police...
2022-01-01T17:36:30 < Xogium> hmm don't know, I never bothered with facebook or any social network and just stick to irc ;)
2022-01-01T17:37:04 < jadew> well me neither, but the idea that you can't even talking about a protest is worrying
2022-01-01T17:37:44 < Xogium> yeah… it doesn't surprise me either
2022-01-01T17:38:01 < jadew> *talk
2022-01-01T17:38:57 < Xogium> its worrying, but it doesn't surprise me…
2022-01-01T17:41:03 < jadew> the whole problem is people don't trust their governments
2022-01-01T17:41:20 < jadew> and because of that, they shouldn't be allowed to impose any measures on their own people
2022-01-01T17:41:42 < jadew> because if they do, it leads up to unrest
2022-01-01T17:42:00 < Xogium> well nah, hard to trust when they take crazy decisions like partial lockdown for just 2 days a week or some equally dumb stuff
2022-01-01T17:42:02 < jadew> and if the people trusted their governments, then they wouldn't need to impose measures to begin with
2022-01-01T17:42:13 < jadew> because they could just inform the population and kindly ask them to wear their fucking masks
2022-01-01T17:42:22 < Xogium> I mean, who doesn't know that covid takes a break on the weekend
2022-01-01T17:42:26 < Xogium> :p
2022-01-01T17:44:00 < Xogium> or what they got in canada, no going outside from 10 pm to 5 am
2022-01-01T17:44:18 < Xogium> like what the hell ? What do they hope to do ?
2022-01-01T17:44:26 < jadew> yeah, we had a similarly stupid measure a while ago too
2022-01-01T17:46:41 < jadew> people are going to start voting for parties against lockdowns and against this kind of crap
2022-01-01T17:48:13 < Xogium> yeah, and it's not like I can blame them
2022-01-01T17:48:23 < Xogium> I'm sick of lockdowns and shit
2022-01-01T17:48:33 < mawk> I caught the chinese virus
2022-01-01T17:48:42 < mawk> that's it, I'm about to die
2022-01-01T17:48:52 < jadew> mawk, you got the confirmation?
2022-01-01T17:49:08 < mawk> I didn't your answer yesterday Xogium , how much hearing will you retain?
2022-01-01T17:49:15 < mawk> it's an autotest jadew 
2022-01-01T17:49:31 < mawk> but someone I spent 2 days with did a PCR test which is positive as well
2022-01-01T17:49:35 < jadew> ah ha, so you eventually did one of those quick tests
2022-01-01T17:49:40 < mawk> yeah
2022-01-01T17:49:43 < jadew> how much did it cost?
2022-01-01T17:49:48 < mawk> it was free
2022-01-01T17:49:51 < jadew> heh
2022-01-01T17:49:54 < mawk> the government sent it into my mailbox
2022-01-01T17:49:58 < jadew> cool
2022-01-01T17:50:02 < jadew> well, at least now you know
2022-01-01T17:50:03 < mawk> but otherwise it's maybe 4 or 5€
2022-01-01T17:50:07 < mawk> in supermarket
2022-01-01T17:50:13 < jadew> what are you going to do in your final days?
2022-01-01T17:50:21 < mawk> drugs, of course
2022-01-01T17:50:24 < Xogium> mawk: highly variable from one day to another but yeah, after 15 or 20 years it could be rather severe. There's no telling really
2022-01-01T17:50:28 < jadew> good plan
2022-01-01T17:50:49 < BrainDamage> if it's any consolation, I've asked a friend in virology and he said that within 2 years or so covid will have fully degenerated to a flu
2022-01-01T17:51:02 < mawk> well it's high time now
2022-01-01T17:51:08 < mawk> it's been 2 years
2022-01-01T17:51:19 < jadew> BrainDamage, I think it already has
2022-01-01T17:51:44 < jadew> at least that's what "they"'re trying to tell us
2022-01-01T17:52:25 < BrainDamage> jadew: not yet, it's generally leaning to, with eg omicron, but it has too become the main strain
2022-01-01T17:52:47 < BrainDamage> and even that one is a bit too deadly yet
2022-01-01T17:52:54 < jadew> BrainDamage, I heard some reports that omicron is the main stream in some parts of the world
2022-01-01T17:53:09 < BrainDamage> some is not all
2022-01-01T17:53:13 < jadew> strain
2022-01-01T17:53:22 < BrainDamage> this has to be worldwide

2022-01-01T21:06:24 < zyp> bitmask, now I understand the thousand lines of example code well enough that I managed to integrate imgui with it, and have started refactoring it into something useful: https://bin.jvnv.net/file/OW58o.png

2022-01-01T21:43:44 <@karlp> well, perhaps not, we actually normally _only_ have the small bit on hinges, the rest of the window is just fixed.
2022-01-01T21:44:05 < PaulFertser> karlp: isn't it too hot during the summer?
2022-01-01T21:51:12 <@karlp> zyp: stop showing pictures of orbtrace and start shipping them ;)
2022-01-01T21:51:33 < zyp> I know, I know
2022-01-01T21:52:45 < Steffanx> lol
2022-01-01T21:53:06 < jpa-> https://jpa.kapsi.fi/stuff/pix/moottoriohjain.jpg   another successful design
2022-01-01T21:53:30 < zyp> very good
2022-01-01T21:55:02 < zyp> isolated H-bridge?
2022-01-01T21:55:14 < jpa-> yeah
2022-01-01T21:55:25 < zyp> what's it for?
2022-01-01T21:55:40 < jpa-> controlling some dc servos for a cnc machine
2022-01-01T21:56:02 < PaulFertser> Did it blue because you used blue wire instead of green?
2022-01-01T21:56:15 < zyp> haha
2022-01-01T21:57:22 < jpa-> my best theory so far is that U1 SY8502 somehow just decided to let the +48V directly to +12V line and that blew the fet drivers
2022-01-01T21:57:38 < jpa-> i wonder how much current is needed to melt off SO8 pin like that
2022-01-01T21:57:54 < jpa-> it had a 5A fuse
2022-01-01T21:58:51 < zyp> maybe you fucked up braking and backfed a bunch of power onto the 12V rail?
2022-01-01T21:59:27 < jpa-> the H-bridge is on the 48V rail and the TVS there appears outwardly intact
2022-01-01T21:59:43 < zyp> ah, of course
2022-01-01T21:59:54 < zyp> got a schematic?
2022-01-01T22:00:06 < jpa-> https://github.com/HacklabJKL/sergei_cnc2/blob/main/electronics/motor_driver/images/motor_driver.pdf
2022-01-01T22:00:25 < zyp> did FAULT_OUT work? :D
2022-01-01T22:01:46 < jpa-> probably for a short time :)
2022-01-01T22:02:23 < jpa-> L6393 pins 8/9/10 are assigned wrong in that schematic and that's what the blue wire is about - it might have short-circuited but i doubt that would explain the behavior
2022-01-01T22:03:09 < jpa-> the motor driver was working very poorly even before it blew up, even though it had worked ok at home
2022-01-01T22:04:13 < zyp> hmm
2022-01-01T22:10:57 < jpa-> heh, U6 VCC pin has welded itself onto the trace
2022-01-01T22:12:50 < catphish> rp2040 has a weirdly complicated clock system, spent way too long trying to work out why USB won't re-negotiate if i change the core clock speed, i still don't know :)
2022-01-01T22:19:11 < jpa-> hmm, U2 and U4 are broken also, so +12V rail must have gone over 30V
2022-01-01T22:28:33 < Steffanx> i think you need another sample
2022-01-01T22:29:01 < kakium69> Steffanx: Den Of Thieves
2022-01-01T22:30:01 < PaulFertser> If the motor driver was working poorly probably one of the FETs or diodes gone bad?
2022-01-01T22:44:18 < jpa-> all the fets are shorted now, but that by itself shouldn't damage the drivers i think

2022-01-01T23:32:36 < bitmask> zyp nice
2022-01-01T23:33:23 < zyp> figuring out uniforms now
2022-01-01T23:33:23 < bitmask> I probably should have started with imgui, i havent looked at it yet, prob would help a lot with debugging :P
2022-01-01T23:34:04 < zyp> yeah, I've used it with opengl before, it's great
2022-01-01T23:34:46 < bitmask> i see it all the time but didnt think i needed it yet, i mean I can use cout like ive been using but im sure theres some situations that cout wont help much
2022-01-01T23:35:04 < zyp> it's not even comparable :)
2022-01-01T23:35:46 < bitmask> for output it is, imgui just allows simultaneous outputs
2022-01-01T23:36:46 < zyp> assuming you're only considering textual outputs, sure
2022-01-01T23:37:06 < bitmask> i gotta start writing things down.  my biggest problem is structuring my programs. I'll get an idea on how i want to change things and I just go file by file making it work for that and then get to a file that wont work that way, so i come up with a tweak and have to go through all the original files and change them, and etc...
2022-01-01T23:37:11 < zyp> https://bin.jvnv.net/file/lEUGA.png
2022-01-01T23:37:24 < zyp> got a variable you want to plot? imgui got you covered
2022-01-01T23:38:16 < kakium69> is imgui your projekt?
2022-01-01T23:38:26 < bitmask> i guess, i cant really think of anything id want to plot right now. thats more for tweaking and stuff id think. im at a stage of it works or it doesnt right now
2022-01-01T23:38:27 < zyp> not at all, it's a common library
2022-01-01T23:39:45 < zyp> well, in my case I'm gonna load up a model of my robot arm and start out with some sliders to set each joint angle
2022-01-01T23:40:26 < bitmask> well sure, thats in the tweaking/use case stage, thats way beyond where I'm at
2022-01-01T23:40:36 < zyp> or I guess before I get to that point I'm gonna add some inputs to set the camera position, once I get the uniforms done so I have a camera position
2022-01-01T23:41:17 < bitmask> ok camera, thats one good example :)
2022-01-01T23:42:30 < bitmask> but im not even there yet, i was but now im backtracking
2022-01-01T23:43:23 < zyp> I'll eventually be too, the code I'm building upon is a mess :p

2022-01-02T00:29:19 < invzim> meh, parts shortage as depressing as ever
2022-01-02T00:31:19 < Steffanx> More depressing than ever
2022-01-02T00:36:28 < jadew> I got my SMA connectors
2022-01-02T00:36:33 < jadew> they were planned for next year
2022-01-02T00:37:14 < jadew> I couldn't make any new boards that were relying on that for about two months - good thing I didn't sell any :P
2022-01-02T00:37:31 < kakium69> did someone say SMA?
2022-01-02T00:37:37 < jadew> heh
2022-01-02T00:37:46 < kakium69> how many?
2022-01-02T00:37:53 < kakium69> many?
2022-01-02T00:38:02 < jadew> one or two hundreds
2022-01-02T00:38:11 < jadew> didn't open the box
2022-01-02T00:38:20 < jadew> and I forgot how many I ordered
2022-01-02T00:39:23 < kakium69> special SMA, generic SMA?
2022-01-02T00:39:40 < jadew> generic thru hole SMA, but high quality
2022-01-02T00:40:57 < jadew> even if they get used once or twice (like they would on my product), they still degrade over time if they're the cheap kind
2022-01-02T00:42:32 < kakium69> you had a sample first?
2022-01-02T00:42:35 < kakium69> samples?
2022-01-02T00:42:43 < jadew> it's the ones I normally use
2022-01-02T00:42:49 < kakium69> yes
2022-01-02T00:43:02 < jadew> but no, I normally don't get samples
2022-01-02T00:44:17 < zyp> bitmask, got the uniforms working as well, so now I've got 3d projection: https://bin.jvnv.net/file/6gw2c.png
2022-01-02T00:44:21 < jadew> this shit takes a lot of time anyway, if I had to wait for samples and then place the order I would waste both money and time
2022-01-02T00:44:33 < kakium69> yes
2022-01-02T00:48:31 < jadew> I want to see a good movie

2022-01-02T00:49:55 < kakium69> 7.0/10
2022-01-02T00:50:07 < kakium69> longish
2022-01-02T00:50:08 < jadew> adventure, thriller, sense of wonder, and maybe taking place in the early 1900 or earlier
2022-01-02T00:50:16 < jadew> will check it out, thanks
2022-01-02T00:50:34 < kakium69> it's a heist movie

2022-01-02T00:58:01 < jadew> what basically happened is that at a sporting event, the crowd was chanting "Fuck Joe Biden!" and the media said they were chanting "Let's go Brandon!"
2022-01-02T00:58:10 < kakium69> okay
2022-01-02T00:58:17 < kakium69> it's actually funny
2022-01-02T00:58:21 < jadew> so now everyone is saying Let's go Brandon, including some politicians in the US :P
2022-01-02T00:58:39 < jadew> and on Christmas, someone said it (live) to the president, and he said it back lol
2022-01-02T00:59:36 < kakium69> they are playing the meme into their advantage ofc.
2022-01-02T01:00:14 < jadew> funny comment on youtube: "If you say "Let's go Brandon" to Joe Biden, he'll think his name is Brandon."

2022-01-02T10:23:31 < jpa-> PaulFertser: i think you might be right about the gate shorting; at least they are shorted now on two of the FETs
2022-01-02T10:24:08 < jpa-> possible theory: one of my blue wires for gate drive got loose, FET floating half-way and heating up quickly, burned to short
2022-01-02T10:24:37 < jpa-> then 48V started going through the gate to the driver chip, and leaked from the driver chip to +12V rail
2022-01-02T10:25:24 < jpa-> and then the +12V being suddenly +48V fried the SMPS chip, causing its FETs to go shorted also, which melted its +48V input pin
2022-01-02T10:26:02 < jpa-> i think i'll add gate series resistors on next version and a TVS diode on +12V rail also
2022-01-02T10:29:36 < PaulFertser> jpa-: sounds like a solid explanation

2022-01-02T12:34:26 < drzacek> hello there
2022-01-02T12:35:17 < drzacek> I'm trying to make a pcb with stm32l431xxxx. got the documentation where all the required pin connections are described and I'm having hard time understanding something
2022-01-02T12:36:36 < qyx> do you have l431?
2022-01-02T12:37:13 < drzacek> https://imgur.com/a/G2xIoVp I'm not sure what they want from me. VDDA is on same pin as VREF+, those are not separate pins
2022-01-02T12:37:17 < drzacek> qyx, I might
2022-01-02T12:38:27 < drzacek> https://imgur.com/a/cph8fVU
2022-01-02T12:39:31 < qyx> higher pin count devices have VDDA and VREF+ separated
2022-01-02T12:40:08 < qyx> just decouple the pin with 1u + 100n and connect to VDD with ferrite bead
2022-01-02T12:40:12 < drzacek> okay. then it makes sense
2022-01-02T12:40:35 < qyx> oh they say 10n on VDDA for whatever reason
2022-01-02T12:41:33 < drzacek> https://imgur.com/a/1Oxh4G7 something like this?
2022-01-02T12:41:46 < qyx> fuk imgur autoplaying videos
2022-01-02T12:42:09 < drzacek> any better alternative for pic sharing?
2022-01-02T12:42:38 < drzacek> tbh I have never seen any video there. ublock?
2022-01-02T12:44:32 < qyx> I have ublock too

2022-01-02T14:48:26 < zyp> karlp, yeah, it's due to abuse, people have tried hosting both malware and phising sites with it

2022-01-02T15:14:19 < mawk> yes kakium69 
2022-01-02T15:14:26 < mawk> in Guyana
2022-01-02T15:15:10 < Steffanx> and where does the kindom of the netherlands has its border with france, kakium69?
2022-01-02T15:16:49 < Steffanx> Out of time.
2022-01-02T15:16:54 < Steffanx> so still alive mr mawk?
2022-01-02T15:17:05 < mawk> of course
2022-01-02T15:21:09 < Steffanx> good
2022-01-02T15:28:54 < mawk> I did a test at the GGD now
2022-01-02T15:29:07 < mawk> they will know I'm contaminated
2022-01-02T15:29:13 < mawk> and call me for contact tracing
2022-01-02T15:30:40 < Steffanx> They're still doing that?

2022-01-02T16:04:39 < englishman> they just stopped testing here
2022-01-02T16:04:44 < englishman> presumably, the numbers were too high
2022-01-02T16:04:56 < englishman> or rather, you have to jump through some kafkaesque hoops
2022-01-02T16:05:15 < englishman> you can get tested if a) you have already received a positive test or b) you have been in contact with someone who has tested positive

2022-01-02T16:58:53 <@karlp> zyp: re: you have that label, that's pretty much it, and from experience, in most places, that list is centrally managed by a vendor anyway, so it's completely opaque.
2022-01-02T17:00:09 < zyp> yeah
2022-01-02T17:01:22 < zyp> wonder if it's just tied to that specific subdomain, so I just could relocate the service to a new subdomain and forward the old
2022-01-02T17:01:40 < zyp> might try that eventually

2022-01-02T17:23:43 <@karlp> hrm, inductor has rated current for both temp rise and saturation, and if both of those are "safely" under my limits from ripple+peak Iout, do I give a shit about DCR of the inductor?  DCR of the inductor goes to the I²R heating, which goes to the rated current for temperature...
2022-01-02T17:24:32 <@karlp> dta sheet app note specifies DCR of 3mOhm, which is twice the price and twice the size of the similarly rated otehrwise inductors...
2022-01-02T17:24:36  * karlp is overthinking again I think.
2022-01-02T17:25:29 < jpa-> karlp: only if you need good efficiency :)
2022-01-02T17:26:19 < jpa-> often SMPS example designs use overrated inductors so that they get that extra 1% of efficiecny
2022-01-02T17:31:39 <@karlp> right, this one is claiming 97% peak efficiency, so I guess I can just cheap out on it.
2022-01-02T17:33:26 <@karlp> this whole family has pads for "Low side power MOSFET gate signal" and then never ever makes mention of them again.
2022-01-02T17:33:48 <@karlp> is that for doing things like stacking external fets as well to get more output, and for doing multi phase stuff?
2022-01-02T17:34:06 < jpa-> which chip?
2022-01-02T17:38:05 < jpa-> some vishay datasheets say "Gate signal output pin for low side MOSFET. Pin for monitoring."

2022-01-02T21:54:42 < zyp> some model I were dicking around with in opengl like ten years ago
2022-01-02T21:54:54 < bitmask> whats the extension
2022-01-02T21:54:57 < zyp> .x
2022-01-02T21:55:03 < bitmask> wtf is that hah
2022-01-02T21:55:09 < bitmask> what are you using to read it in
2022-01-02T21:55:13 < zyp> assimp
2022-01-02T21:55:16 < bitmask> ahh
2022-01-02T21:56:49 < zyp> it loads .stl files just as well: https://bin.jvnv.net/file/hFNyy.png
2022-01-02T21:56:50 < bitmask> maybe I shouldn't have gone the path of writing my own importer :P
2022-01-02T21:57:00 < zyp> that's some shit I 3d printed once
2022-01-02T21:57:42 < zyp> got any interesting gltf files I can try?
2022-01-02T21:58:02 < bitmask> go on sketchfab
2022-01-02T21:58:05 < BrainDamage> i've used assimp in the 3d engine i helped writing > 10y ago and i can tell you it's pretty decent to use
2022-01-02T21:58:58 < bitmask> my importer only supports obj (most of) and glTF (half of)
2022-01-02T21:59:22 < bitmask> and even that doesnt work yet because i have to change my internal format to get it working again
2022-01-02T21:59:38 < bitmask> but im getting close to that point now

2022-01-03T00:57:36 < bitmask> nice, importing the stl?
2022-01-03T00:57:44 < zyp> .obj, as you can see

2022-01-03T00:58:07 < bitmask> ahh didnt zoom in
2022-01-03T00:59:05 < bitmask> I think im gonna get rid of obj support and just use glTF for everything
2022-01-03T00:59:53 < zyp> I defined all the joints in fusion 360, but I don't think there's any way of exporting that information in a useful manner
2022-01-03T01:00:04 < bitmask> yea i doubt it
2022-01-03T01:01:15 < bitmask> I haven't dealt with joints yet but since your use case is so simple it might be worth it to just use separate objects for each section
2022-01-03T01:02:00 < bitmask> actually no thats probably not true, i just dont know enough to joints yet, how they are defined
2022-01-03T01:02:10 < bitmask> enough about*
2022-01-03T01:02:54 < zyp> depends on the file format, I guess
2022-01-03T01:03:13 < zyp> either way it's gonna end up as a set of meshes in a scene graph

2022-01-03T10:39:37 < jadew> for example, there's this project asking you to design a mouse that tracks head movement - they expect a finished product, and it's 2k fixed price
2022-01-03T10:39:39 < jadew> like... wtf
2022-01-03T10:40:54 < jadew> they have a section where people can post "gigs" now
2022-01-03T10:40:59 < jadew> they're almost entirely indians
2022-01-03T10:41:20 < jadew> is freelancing no longer available to the rest of the world?
2022-01-03T10:42:04 < Steffanx> PlayStation cam. IR LEDS. Done.
2022-01-03T10:42:28 < jadew> they need a stand alone device (that is cheap)
2022-01-03T10:42:48 < jadew> and I think they want to be mounted on the hand or something - unclear
2022-01-03T10:42:58 < Steffanx> Not sure why PS cameras were popular for this. Maybe a non-standard high frame rate?

2022-01-03T10:58:32 < jadew> I like the jobs that start with: "_I'm_ building an app. The app needs to: "
2022-01-03T10:58:45 < jpa-> jadew: freecancer and upwork are always full of underpaid or poorly specified stuff.. takes lot of searching to find reasonable projects
2022-01-03T10:59:41 < jpa-> also if the project seems reasonable, you can bid over the price range and with a good description of what you would do
2022-01-03T10:59:45 < Xogium> lol the _I'M_ it makes it sounds like they are the one that will do the work when they are in fact hiring you
2022-01-03T11:00:42 < jadew> jpa-, it looks a lot worse now than it used to be 15 years ago
2022-01-03T11:01:39 < jpa-> i didn't know freelancer/upwork existed 15 years ago :)
2022-01-03T11:01:56 < jadew> other stuff that freelancer bought did exist tho :)
2022-01-03T11:02:15 < jpa-> but even with careful selection, my freelancer/upwork projects have averaged somewhere around 40 EUR/h, whereas projects i get outside the platforms are usually happy to pay 80 EUR/h - so i only do upwork stuff when i don't have anything else
2022-01-03T11:02:49 < jadew> that's not bad I guess
2022-01-03T11:03:45 < jpa-> https://www.upwork.com/freelance-jobs/apply/Get-Paid-for-Developing-Application-Notes_~019ed89adf278876c1/    this greenpak application note thing was fun
2022-01-03T11:04:06 < jadew> oh, I got accepted into that one too
2022-01-03T11:04:20 < jadew> and had several ideas, but decided to keep them for myself lol
2022-01-03T11:04:30 < jpa-> did you get an application note idea accepted? i did one, and after that i just couldn't come up with anything they would accept :D
2022-01-03T11:04:41 < jpa-> haha, classic jadew
2022-01-03T11:04:42 < jadew> I didn't submit mine
2022-01-03T11:04:51 < jadew> I had like 5 good ones
2022-01-03T11:06:03 < jpa-> so why are you keeping them to yourself? are you assuming you can make a product out of it that nets you more than $1000?
2022-01-03T11:06:20 < jadew> yeah, I was actually planning to use one of their devices for an older project of mine
2022-01-03T11:06:30 < jadew> the solution was quite creative for a rather difficult problem
2022-01-03T11:06:44 < jadew> I still hope that I might get back to it
2022-01-03T11:07:06 < jadew> and if I do, I don't want to leave the blueprint to getting cloned, on their website
2022-01-03T11:07:21 < Steffanx> Lol jadew. Have you actually had any benefits from this "keep this for myself"-attitude yet? 
2022-01-03T11:07:51 < jadew> Steffanx, no, but I had negative benefits from sharing stuff
2022-01-03T11:07:56 < jadew> I wasn't always like this :)
2022-01-03T11:08:58 < Steffanx> Now we'll probably never know if the ideas are actually good or just good in your head ;)
2022-01-03T11:09:39 < jadew> well, I know those related to greenpak are good, because they would solve an issue that I couldn't solve any other way
2022-01-03T11:09:59 < jadew> not sure how valuable it really is tho, and I won't know until I try to sell the product - if ever :)
2022-01-03T11:10:12 < jpa-> but you didn't actually *do* it, so you don't really know if it even works as well as you think
2022-01-03T11:10:27 < jpa-> reality has a habit of showing you what you don't know
2022-01-03T11:10:31 < jadew> yeah, I guess there's that too, but I did research it well enough
2022-01-03T11:10:46 < jadew> this was before the company that made those devices got aquired by dialog
2022-01-03T11:10:53 < jadew> I think they were called silego or something like that
2022-01-03T11:11:53 < jpa-> jadew's ideas must really be stellar to be worth sitting on for 5 years - my clients usually worry that if their time-to-market is 1 year, their products will be outdated
2022-01-03T11:13:35 < Steffanx> I think its as great as your latest fume removal trigger jpa-  :D
2022-01-03T11:13:57 < jadew> what fume removal trigger? :)
2022-01-03T11:14:18 < Steffanx> When I read the title I thought: im curious what he came up with.  Turns out it's "just" using a photo diode 
2022-01-03T11:14:44 < jpa-> Steffanx: i actually considered greenpak for that, but i'm always too lazy to add a voltage regulator
2022-01-03T11:14:50 < Steffanx> Read his latest blog/project post jadew 
2022-01-03T11:15:29 < jadew> oh, I didn't realize he's blogging that much
2022-01-03T11:15:52 < Steffanx> The best part is the professionally made PCB.
2022-01-03T11:16:15 < jadew> lol, you said that right before I scrolled one page down and got to it hehe
2022-01-03T11:17:35 < jadew> it doesn't look bad
2022-01-03T11:18:24 < jadew> quite clever really
2022-01-03T11:23:34 < jadew> jpa-, how did you make this? http://essentialscrap.com/brass_figures/brass-tulip.jpg
2022-01-03T11:23:58 < jadew> the blog post says you did it with a knife, but it looks smoother than I would expect it to be
2022-01-03T11:24:10 < jadew> did you polish it afterwards?
2022-01-03T11:26:30 < jpa-> yeah, polished with sandpaper and then polishing paste
2022-01-03T11:26:42 < jpa-> i probably used dremel also
2022-01-03T11:26:48 < jadew> the toy car thing is awesome
2022-01-03T11:26:59 < jadew> if you made a video on it, it would have had 10 million views
2022-01-03T11:27:13 < jadew> (on youtube)
2022-01-03T11:27:50 < jpa-> i was quite limited in my potato quality cameras back then :)
2022-01-03T11:28:39 < jadew> I made a toy car for my newphew, but something happened! (DIY toy car, arduino, esp32, eevblog)
2022-01-03T11:28:41 < jadew> ""
2022-01-03T11:29:15 < jadew> I'm serious tho, I think it would have had a lot of traffic
2022-01-03T11:29:34 < jadew> it's the kind of project that requires many skills that men like to watch other men perform
2022-01-03T11:29:59 < jpa-> yes, a well made video on reasonable project would probably eventually get a reasonable amount of views - but making a good video is a significant amount of effort
2022-01-03T11:31:26 < jpa-> so far i haven't bothered trying to go into video production.. it would take years of effort before it starts paying back in ad money, and i'm not interested in it as a hobby currently
2022-01-03T11:33:55 < jadew> btw, your favicon looks a little like the chinese flag
2022-01-03T11:40:52 < Steffanx> But we are interested jpa-  
2022-01-03T11:41:00 < Steffanx> Or maybe not. 🤔
2022-01-03T11:41:20 < Steffanx> Maybe your parrot can do the voice overs
2022-01-03T11:41:39 < jpa-> maybe you can do them!
2022-01-03T11:41:39 < Steffanx> The kid can be the helpful helper. 
2022-01-03T11:41:46 < zyp> fenugrec, yeah, I know what color it is, actual arm looks like this: https://bin.jvnv.net/file/2pVce.jpg
2022-01-03T11:42:25 < Steffanx> Nah, I dont have a voice over voice. jpa-  
2022-01-03T11:42:30 < zyp> I'll make the model prettier later, just want to make the kinematics work first
2022-01-03T11:43:41 < jpa-> zyp: i'm too lazy to read logs, so now you'll need to write a TLDR for me; are you using that robot arm for work or hobby, what software platform, etc.
2022-01-03T11:44:06 < zyp> hobby, it's something I got for free
2022-01-03T11:44:42 < zyp> it's 25 years old, so I'm planning to replace the original controller with something more modern
2022-01-03T11:44:43 < jpa-> i tried to use a robot arm with ROS, was terribly confusing; it might have been easier to go with linuxcnc after all, it seems to have improved the non-linear kinematics support a lot in past few years
2022-01-03T11:45:11 < zyp> yeah, I've looked at ROS, but it looks too complex to be worthwhile
2022-01-03T11:46:11 < jpa-> https://jyvaskyla-hacklab-fi.translate.goog/2019/10/05/ros-integraatio-robokadelle/?_x_tr_sl=fi&_x_tr_tl=en&_x_tr_hl=fi   i got this far, and even had single moves working with ROS moveit but then i didn't know how i should actually control it from e.g. gcode
2022-01-03T11:47:33 < zyp> yeah, lots of robot arm stuff seems to be aimed at pick&place work where only the end points really matter, not the path
2022-01-03T11:48:31 < jpa-> linuxcnc with the genserkins module seems quite straightforward, just needs the joint definitions like this:  https://github.com/LinuxCNC/linuxcnc/blob/325caafff458f6675d3954885a951078b5c433e0/configs/sim/axis/vismach/melfa-sim/melfa_dh.hal
2022-01-03T11:48:54 < jpa-> and can load .stl files for the 3d display
2022-01-03T11:49:38 < zyp> might try that later
2022-01-03T11:49:51 < zyp> but I'm also considering just doing my own controller
2022-01-03T11:50:05 < jpa-> if you can communicate in realtime (less than 1 ms latency or so) with the motors and encoder feedback, you can do servo loop on PC; if not, you can just send the target positions and do servo loop in hardware
2022-01-03T11:51:05 < jpa-> what i really like about linuxcnc is that the user interface is low latency also - compared to some grbl etc. stuff where a freaking pause button press takes over a second to take effect because of some silly queues

2022-01-03T11:51:46 < zyp> I'm planning to do something ethercat-ish on those cheap fpga modules with two gigabit interfaces, so I figure I can do 10kHz cycle rate easily, as long as I can run the kinematics fast enough :)
2022-01-03T11:52:43 < jpa-> compile the mesa electronics 7i76e VHDL code for tha FPGA board and it'll hook right up to linuxcnc ;)
2022-01-03T11:53:19 < jpa-> the mesa electronics fpga boards are actually pretty nice to use, but the VHDL code is pretty horrible mess
2022-01-03T11:53:25 < zyp> just not sure I want linux involved in the realtime path
2022-01-03T11:53:45 < jpa-> are you going to make your own user interface also?
2022-01-03T11:54:22 < zyp> maybe, I already have a gcode parser and stuff from when I did my own 3d printer controller
2022-01-03T11:54:24 < jpa-> because in my experience, you don't want huge queues between user interface and the hardware
2022-01-03T11:54:46 < zyp> yeah, I know
2022-01-03T11:54:50 < jpa-> :)
2022-01-03T11:55:28 < jpa-> do you have plans what you are going to give it to hold? a sword? a laser? a plasma cutter?
2022-01-03T11:55:33 < zyp> 3d printer firmware can queue up like a minute worth of moves and currently doesn't respond to anything before it's done :p
2022-01-03T11:57:24 < Xogium> linux can be compiled with realtime by the way
2022-01-03T11:57:33 < Xogium> just saying
2022-01-03T11:57:40 < zyp> yeah, I know, but still
2022-01-03T11:58:23 < zyp> jpa-, 3d printer extruder and a router spindle are obvious options :)
2022-01-03T11:58:52 < zyp> plasma as well, I guess
2022-01-03T12:00:00 < jpa-> :)
2022-01-03T12:00:36 < zyp> something like this, perhaps: https://www.aliexpress.com/item/32944532381.html
2022-01-03T12:00:41 < jpa-> take the easy path and use linuxcnc for motion control, and spend your time writing a good 5-axis 3D printer slicer or CNC CAM software :)
2022-01-03T12:00:52 < jpa-> because there is a real lack of those in open source world
2022-01-03T12:01:20 < jpa-> that's a fancy spindle
2022-01-03T12:03:30 < srk> pause and queues are really bad for CNCs where you sometimes need to pause instantly or else you breat a tool :D
2022-01-03T12:04:00 < srk> there's some ROS industrial package that's supposed to be able to handle gcode / tool paths
2022-01-03T12:04:02 < Steffanx> Some nice CNC CAM sw yeah. Fusion 360 CAM is pretty easy to use,  but they keep removing features from the free version.
2022-01-03T12:04:31 < srk> FreeCADs CAM is pretty nice
2022-01-03T12:04:47 < srk> no 5 axis tho
2022-01-03T12:05:07 < Steffanx> Never tried that one. Only solidworks  and fusion. Solidworks is just tooo much
2022-01-03T12:05:56 < zyp> jpa-, I figure with a tool changing spindle I just need to put a tool rack somewhere within the reach and the arm can just go over and switch tools, so the only expensive part of it is the spindle itself
2022-01-03T12:06:34 < zyp> compared to a cartesian mill with a limited working area
2022-01-03T12:07:43 < jpa-> yeah
2022-01-03T12:13:23 <@karlp> jpa-: that's a pretty fancy opamp for a led watcher, guesing that was "in stock" ? :)
2022-01-03T12:18:10 < jpa-> yeah :D
2022-01-03T12:18:37 < jpa-> i would have had LM324 but it was a quad so waaaay too large ;)

2022-01-03T12:34:14 <@karlp> what you planning on building at that scale?
2022-01-03T12:34:19 <@karlp> "because I have a big robot" ?
2022-01-03T12:34:29 < zyp> pretty much, yes :)
2022-01-03T12:34:38 <@karlp> perfectly reasonable answer :)
2022-01-03T12:54:09 < jadew> jpa-, I also noticed you're doing blogging wrong
2022-01-03T12:54:23 < jadew> the link to the JBC station is not an affiliate link
2022-01-03T12:57:07 < jadew> that said, I'm kinda tempted to get that station too
2022-01-03T12:57:14 < jadew> it looks really nice
2022-01-03T13:00:18 < jadew> I was considering this: https://www.aliexpress.com/item/1005003422171697.html
2022-01-03T13:00:22 < jadew> but that JBC is really well priced
2022-01-03T13:05:22 < jpa-> yeah - JBC tips are quite expensive though
2022-01-03T13:06:50 < jadew> but I hear they last longer
2022-01-03T13:07:03 < jadew> not sure how that works out over the long term tho
2022-01-03T13:25:45 <@karlp> that t3a/t3b is what peterm was raving about iirc.
2022-01-03T13:28:34 <@karlp> I don't quite get what the T210 vs t115 handles difference really is though
2022-01-03T13:33:52 < jadew> karlp, yeah, I've seen some good reviews of that station
2022-01-03T13:34:49 <@karlp> oh, it's direct jbc compat with there precision and nano handles I guess.
2022-01-03T13:35:23 < jadew> yeah, but I wonder how it compares to a proper JBC station, in terms of regulation
2022-01-03T13:35:53 <@karlp> and so jpa's is the "245" size, so bigger than either of the t3a/t3b...
2022-01-03T13:36:22 <@karlp> ah no, t3a has "245" size, https://www.aliexpress.com/item/1005003723078740.html and t3b has "210" and "115" size.
2022-01-03T13:37:27 < jadew> I think I posted this review before: https://www.youtube.com/watch?v=26KXtHZqhMg
2022-01-03T13:39:55 < jadew> oh, this is the T3B one: https://www.youtube.com/watch?v=Ds2Xq3dwV30
2022-01-03T14:14:50 < jpa-> AFAIK the same stations are compatible with T210 and T245, but it varies which handle it ships with
2022-01-03T14:15:25 < jadew> the difference in power makes the choice difficult tho
2022-01-03T14:15:46 < jadew> personally, I wouldn't mind 200 Watts

2022-01-03T15:09:48 < jpa-> from finnish corona guidance: "If you have a positive home test result, you must voluntarily avoid contacts for 10 days."
2022-01-03T15:10:04 < jpa-> this "you must voluntarily" is getting popular here :)
2022-01-03T15:10:10 < jadew> you must
2022-01-03T15:13:51 < Steffanx> Heh, here some international covid flight arrived. The people had to go into voluntary lockdown in a hotel. A spanish couple left and got arrested on their way home 😅 
2022-01-03T15:16:06 < Steffanx> Are the any consequences when you dont avoid contacts for 10 days jpa- ? 
2022-01-03T15:16:23 < jadew> There always are if it's voluntary.
2022-01-03T15:17:32 < jpa-> Steffanx: probably only if something happens, e.g. if it can be proven you caused an outbreak or something
2022-01-03T15:17:59 < jadew> like they can prove that...
2022-01-03T15:18:00 < jpa-> it is "voluntary" because a home test cannot be legally binding here
2022-01-03T15:19:25 < jpa-> jadew: yeah, so far there has been one case where some elderly woman died because their caregiver came to work after covid exposure; the charges were dropped
2022-01-03T15:21:01 < jadew> you can cough in someone's face while having symptomatic covid, while on camera and nobody can prove that they got it from you, unless you were the only person who had contact with them in the past however many weeks
2022-01-03T15:22:28 < jpa-> there have been convictions about intentional spreading of HIV though, so i'm not sure if that is easier to prove for some reason
2022-01-03T15:23:15 -!- veverak1 is now known as veverak
2022-01-03T15:23:33 < Steffanx> Someone (or probably more) here got 3 weeks jail time for exactly that jadew.
2022-01-03T15:24:12 < jadew> you can argue that the intent was bad, and it deserves punishment
2022-01-03T15:24:24 < jadew> and yeah, I can see that happening
2022-01-03T15:26:23 < jadew> it's also a matter of how wide spread a disease is also
2022-01-03T15:27:22 < jadew> you can't prove without reasonable doubt that you caught covid from someone at work, because lots of people have covid and it's easy to catch it
2022-01-03T15:27:28 < Steffanx> How's mawk handling the intruder?

2022-01-03T15:44:18 < Xogium> what the hell ? Why are they some grove cables that don't have the clip ? Why would you even want to have unbuckled cables ?
2022-01-03T15:44:31 < Xogium> *why is there, rather
2022-01-03T15:44:49 < Xogium> like… I mean, even when prototyping… I don't get the idea
2022-01-03T15:44:59 < Xogium> when prototyping those don't hold any good
2022-01-03T15:46:05 < Xogium> the cables that came with my buzzers were the unbuckled kind. And here I was wondering why it never held and always kept falling off
2022-01-03T15:47:08 < Xogium> I heard of stemma connectors but never played with those yet. I like grove though so far… at least, when you get buckled cables
2022-01-03T15:47:30 < Xogium> I can't accidentally connect the stuff the wrong way and blow it up
2022-01-03T15:52:37 < Steffanx> Unbuckled connectors in the right socket aren't that loose in my experience..
2022-01-03T15:52:48 < Xogium> really ?
2022-01-03T15:53:01 < Steffanx> Yeah
2022-01-03T15:53:17 < Xogium> I'll be damned… all the ones I tried, tthat is on the 3 boards I got from seeed were looss as hell

2022-01-03T15:54:08 < Xogium> like shift the wire a tiny bit around and poof it fell off
2022-01-03T15:54:17 < Steffanx> Time to buy a nice set of buckled ones?
2022-01-03T15:54:23 < Xogium> yup
2022-01-03T15:56:31 < Xogium> one of the buzzer was sent flying off somewhere, I heard it ping around
2022-01-03T15:56:45 < Xogium> though, no idea where exactly… Good thing I got 5 of them, I guess
2022-01-03T15:58:54 < Xogium> I just kind of wish I knew unbuckled was a thing and that it came with that :p
2022-01-03T16:00:04 < Steffanx> Time to crawl over the floor trying to find it? 
2022-01-03T16:00:20 < Xogium> yeah… sigh

2022-01-03T16:03:20 < Xogium> holy jesus that buzzer is LOUD
2022-01-03T16:03:36 < Xogium> something like 90 db… it's an active piezo buzzer
2022-01-03T16:04:10 < Xogium> or well
2022-01-03T16:04:33 < Xogium> its both an active and passive, I guess ? It can be used simply with a 5v/3v current, or with pwm

2022-01-03T17:37:35 < ventYl_> coming across // TODO: temporary solution for something in version 1.5
2022-01-03T17:37:42 < ventYl_> in code which is like  version 15
2022-01-03T17:38:32 < Steffanx> Must have been a wonderful solution then
2022-01-03T17:39:03 < ventYl_> more like this codebase is full of temporarilly permanent solutions and wonky architecture
2022-01-03T17:39:28 < Xogium> hey ventYl_ :) happy delayed new year :p
2022-01-03T17:39:43 < ventYl_> i bet that this thing is able to cause segmentation fault just by exhausting stack doing it's normal business
2022-01-03T17:40:07 < ventYl_> Xogium: hey Xogium, happy delayed new year. hope your uint32_t won't overflow due to it
2022-01-03T17:40:20 < ventYl_> hm, it was int32_t in microsoft
2022-01-03T17:40:22 < Xogium> hehe
2022-01-03T17:40:39 < Xogium> why would it overflow ?
2022-01-03T17:41:28 < ventYl_> because they put it together like year . month . day . hour . minute . second
2022-01-03T17:41:39 < Xogium> .... not that again
2022-01-03T17:42:07 < ventYl_> which put 21 on two most significant decadic places last year. that was just a tad bit under the limit of overflow
2022-01-03T17:42:14 < ventYl_> and 22 obviously overflows
2022-01-03T17:42:36 < Xogium> oh
2022-01-03T17:42:55 < Xogium> but… didn't they fix that in advance ? Couldn't they predict this ?
2022-01-03T17:43:46 < ventYl_> no, it started failing after new year, so we have whole new unexpected class od y2k22 bugs :)
2022-01-03T17:43:51 < Steffanx> I https://support.xilinx.com/s/question/0D52E00006uxy49SAA/vivado-fails-to-export-ips-with-the-error-message-bad-lexical-cast-source-type-value-could-not-be-interpreted-as-target?language=en_US xilinx does something similar.
2022-01-03T17:44:25 < Xogium> charming…
2022-01-03T17:45:08 < Xogium> hm
2022-01-03T17:45:21 < Xogium> reminds me of the stupid gpsd rollover bug
2022-01-03T17:45:40 < ventYl_> that's bug mostly inherent to gps itself
2022-01-03T17:45:46 < ventYl_> or stupid implementations
2022-01-03T17:45:48 < Xogium> yeah
2022-01-03T17:46:14 < ventYl_> i wonder how gps-guided missiles deal with it
2022-01-03T17:46:31 < Xogium> but gpsd was upgraded even though it introduced a breaking change in the latest lts release of buildroot

2022-01-03T17:46:51 < Xogium> they had no choice though
2022-01-03T17:46:59 < Xogium> gspd folks didn't backport the fix
2022-01-03T17:47:34 < ventYl_> how old was the branch of gpsd used in buildroot?
2022-01-03T17:47:49 < Xogium> hmm
2022-01-03T17:48:13 < Xogium> it dates from 2020, think it is 3.22 or 3.21

2022-01-03T17:48:26 < Xogium> lts of buildroot are supported for one year
2022-01-03T17:48:45 < ventYl_> not the buildroot, but the gpsd
2022-01-03T17:48:56 < Xogium> yeah 3.22 or 3.21 of gpsd I mean
2022-01-03T17:48:59 < Xogium> I forget which
2022-01-03T17:49:03 < ventYl_> i'd say that such a fundamental feature would be fixed in any supported version
2022-01-03T17:49:34 < PaulFertser> It's not like someone prohibits buildroot maintainers from backporting the fix :)
2022-01-03T17:49:53 < Xogium> so buildroot folks had to bump gpsd in the midle of the lts cycle, even though it introduced breaking changes that blew my apps apart
2022-01-03T17:49:54 < PaulFertser> gpsd is being developed in a kind of "agile" way.
2022-01-03T17:50:13 < PaulFertser> Xogium: they could backport the change themselves if they cared.
2022-01-03T17:50:18 < ventYl_> so it was unsupported for some reason, maybe gpsd developers were learning versioning at openssl or freecad, or buildroot was using ancient version of gpsd by that time, because, why not?
2022-01-03T17:50:36 < Xogium> they didn't feel like it was trivial to port, apparently, so that's why they didn't backport it
2022-01-03T17:50:51 < PaulFertser> Not every work is supposed to be trivial.
2022-01-03T17:50:51 < Xogium> the buildroot folks looked at it, and decided to not carry any additional patches
2022-01-03T17:53:37 < Xogium> but yeah, forcing the update was not nice, but carrying a bunch of patches more they wanted to avoid
2022-01-03T17:53:54 < Xogium> on other packages there's a shit ton of patches
2022-01-03T17:53:59 < Xogium> like grub2
2022-01-03T17:54:13 < Xogium> grub2 has something like 110 patches
2022-01-03T17:55:37 < ventYl_> why caused it to break the environment? newest version is like 3.22
2022-01-03T17:55:41 < ventYl_> 3.22.1
2022-01-03T17:55:49 < ventYl_> 3.23.1
2022-01-03T17:55:58 < Xogium> ah must have been 3.20 or 3.21 version then
2022-01-03T17:56:18 < ventYl_> that doesn't sound like there should be anything broken between 3.20 and 3.23
2022-01-03T17:57:00 < Xogium> the gpsd abi or api ? I don't recall which, isn't stable. So software I used relied on something the api used to expose one way, but now does a different way
2022-01-03T17:57:23 < Xogium> so it blew up at compile
2022-01-03T17:57:51 < ventYl_> so they got their versioning paradigma from openssl
2022-01-03T17:58:41 < Xogium> yeah something like that
2022-01-03T17:58:48 < ventYl_> that's fucking disgusting
2022-01-03T17:59:10 < Xogium> yeah, sure was not fun
2022-01-03T17:59:36 < Xogium> I think  introducing the patch that backports the leap second fix would have also broke the versioning
2022-01-03T17:59:39 < Xogium> I'm not sure
2022-01-03T17:59:56 < Xogium> but the excuse of the gpsd folks for not doing it was it isn't trivial

2022-01-03T18:03:15 < Xogium> I don't know a thing about gps let alone iternals of gpsd, so I don't criticize them, but… it's a bit annoying in its versioning
2022-01-03T18:06:33 < ventYl_> I hardly can think of something which could be introduced into GPS, that would warrant API/ABI breaking change between minor versions
2022-01-03T18:06:56 < ventYl_> "we do agile development" is kind of stupid excuse for not caring about API/ABI stability
2022-01-03T18:07:15 < ventYl_> freecad is similarly annoying in this way
2022-01-03T18:07:18 < ventYl_> yet probably even more
2022-01-03T18:07:21 < Xogium> yeah… let me find what broke again
2022-01-03T18:09:23 < Xogium> Move gps_data_t->status to gps_fix_t.status for better fix merging

2022-01-04T08:07:33 < jpa-> on linux mouse middle button pastes whatever is selected in other window; because there is no copy event the javascript never fires

2022-01-04T08:10:59 < Xogium> just for me it is ins+c ;) makes it much safer it looks like
2022-01-04T08:11:56 < Xogium> damn useful to also copy the lines of interesting output from a program, too
2022-01-04T08:12:30 < Xogium> copying from a terminal is quite… complicated if you're blind, aside from with that method
2022-01-04T08:12:51 < Xogium> surprisingly hard to do, fact the only thing I ever managed was select all kind of copy
2022-01-04T08:13:41 < Xogium> but then again the only useful gui terminals we can use more or less correctly are VTE based, and VTE sucks

2022-01-04T09:47:53 < ventYl_> microsoft got back to their usual stuff. they *just* want to finish setup of my device by adding windows hello and reset recommended browser settings
2022-01-04T09:49:50 < Xogium> oh yeah that stuff
2022-01-04T09:50:05 < Xogium> I get it randomly in my vm too
2022-01-04T09:51:27 < Xogium> at least you can bypass it… for now
2022-01-04T09:51:40 < Xogium> who knows what they'll pull off next
2022-01-04T09:54:47 < Xogium> ventYl_: were you able to fix espeak's serialized dict generation ?
2022-01-04T09:54:53 < Xogium> just checking :)
2022-01-04T10:07:53 < ventYl_> Xogium: i chose to simply don't give a damn around christmas

2022-01-04T10:13:31 < Xogium> its perfectly fine
2022-01-04T10:13:58 < Xogium> I didn't expect you to, but just wanted to check up on it anyway

2022-01-04T10:29:32 < ventYl_> I will first fix crashing with serialized dict, then proceed with voices
2022-01-04T10:33:04 < Xogium> that sounds like a plan
2022-01-04T11:37:58 < drzacek> hello there
2022-01-04T11:38:32 < drzacek> I got me one of these https://www.st.com/en/evaluation-tools/nucleo-h723zg.html and I'm trying to get the LAN working on it
2022-01-04T11:39:09 < drzacek> till now I thought most cubemx options were pretty self-explanatory, but man this lwip is one complex mf
2022-01-04T11:39:49 < drzacek> and it tells me this https://imgur.com/a/w5nkVnp
2022-01-04T11:40:09 < drzacek> I have no idea what it wants from me. If it wants to look at some address why don't it? I'm fine with it
2022-01-04T11:45:24 < ventYl_> well, I would discuss reference manual
2022-01-04T11:46:00 < drzacek> I guess so
2022-01-04T11:46:20 < ventYl_> for me with 0 knowledge of eth PHY this message is vague in term, if RAM base address is wrong or some base address is configured "unsuitably" in ETH PHY
2022-01-04T11:49:09 < Xogium> why do people always use screenshots ?
2022-01-04T11:49:18 < Xogium> not complaining… just honestly wondering
2022-01-04T11:49:25 < zyp> IIRC the ram on H7 can be accessed through different buses by using different area ranges, but the ethernet DMA is probably only connected to the bus using the 0x24000000 address range
2022-01-04T11:49:26 < drzacek> what else should they use?

2022-01-04T11:50:15 < zyp> so if you're giving the ethernet DMA pointers from the other address range, it'll fail when trying to read or write memory
2022-01-04T11:50:53 < ventYl_> Xogium: i wanted to complain as well, but it seems that this particular bunch of text is not copy-paste ready
2022-01-04T11:50:54 < Xogium> drzacek: well I don't know the context here but pastebin ?

2022-01-04T11:51:11 < drzacek> and how do I copy the window contents as text?
2022-01-04T11:51:15 < zyp> Xogium, it's a screenshot from cubemx
2022-01-04T11:51:37 < Xogium> I'm not complaining, it just bothers me to see screenshots, because I know I can't help whoever posted that, should I have the answer to their trouble
2022-01-04T11:52:03 < drzacek> I seriously don't see how this could be replaced by a text-based paste
2022-01-04T11:52:19 < zyp> Xogium, I understand that, but a lot of text like that is not selectable and hence a screenshot is the easiest option
2022-01-04T11:52:34 < Xogium> zyp: :O really ?
2022-01-04T11:52:45 < Xogium> man, I feel super dumb
2022-01-04T11:53:03 < Xogium> I always thought that if my screen reader could select and copy the text, then so could sighted people
2022-01-04T11:54:42 < Xogium> this is puzzling
2022-01-04T11:56:39 < drzacek> I *COULD* copy each line separately and paste it into text, but then some information would be lost, and the formatting would take forever so it looks readable
2022-01-04T11:57:20 < drzacek> also if people here are familiar with cubemx interface they might directly figure out where this is and whats the solution (or so I hope)
2022-01-04T11:58:04 < Steffanx> It's a table in some java ui Xogium. You don't want to copy that one by one. If that's even possibles 
2022-01-04T11:58:24 < Xogium> oh
2022-01-04T11:58:34 < Xogium> sounds like a mess alright
2022-01-04T11:58:49 < Steffanx> Yes sir
2022-01-04T11:59:54 < ventYl_> in long run there is little to none advantage in using gui
2022-01-04T12:00:53 < Xogium> only use it for the browser, these days…
2022-01-04T12:01:24 < ventYl_> just because web is POS in regards of information retrieval
2022-01-04T12:02:02 < ventYl_> typically you have 10000:1 ratio of garbage vs. information
2022-01-04T12:02:07 < zyp> hmm, going by RM0468, the ethernet MAC DMA can access SRAM1, SRAM2 and AXI SRAM, just not DTCM, ITCM and SRAM4
2022-01-04T12:02:38 < zyp> shouldn't be an issue
2022-01-04T12:02:39 < Xogium> heh
2022-01-04T12:03:03 < drzacek> thats the one I'm reading right now
2022-01-04T12:04:46 < zyp> I'm not sure how memory use is set up by default, but DTCM is mapped at the traditional 0x20000000 with AXI SRAM at 0x24000000
2022-01-04T12:05:49 < zyp> so the warning is probably trying to tell you that you can't put DMA buffers in the 0x20000000 area, but I'm not sure if it's telling you that because you're attempting to do that, or if it always does
2022-01-04T12:06:45 < ventYl_> well, addresses below point somewhere into 0x30000000 area
2022-01-04T12:08:10 < zyp> oh, right, I didn't look that far :)
2022-01-04T12:08:54 < zyp> 0x30000000 is SRAM1, so they should also be valid
2022-01-04T12:09:15 < drzacek> well it's mostly default options
2022-01-04T12:09:28 < zyp> I mean, SRAM1 makes sense
2022-01-04T12:09:57 < drzacek> this chip is way more complex that my blue pill f1
2022-01-04T12:10:18 < ventYl_> yeah, stm32*7 are built for high data throughtput
2022-01-04T12:10:19 < zyp> the ethernet DMA is hooked to the AHB bridge, meaning SRAM1 is a shorter path than AXI SRAM
2022-01-04T12:10:34 < ventYl_> you can put shitload of data through it virtually without involvemenet of CPU
2022-01-04T12:10:42 < zyp> and DMA buffers like that are a good use of discontinous blocks like that
2022-01-04T12:11:18 < zyp> so I wouldn't worry too much about the warning
2022-01-04T12:11:39 < zyp> f103 doesn't even have ethernet, so that's not a fair comparison
2022-01-04T12:11:46 < zyp> but yeah
2022-01-04T12:11:57 < drzacek> sounds nice
2022-01-04T12:12:03 < drzacek> well, it does
2022-01-04T12:12:13 < drzacek> (w5500, via spi)
2022-01-04T12:12:19 < zyp> the thing is that cortex-m7 has a 64-bit AXI bus, while the other cortex-m variants only have 32-bit AHB buses
2022-01-04T12:12:28 < drzacek> axi? ahb?
2022-01-04T12:12:31  * drzacek cries in dumb
2022-01-04T12:12:48 < zyp> look at page 107 in RM0468
2022-01-04T12:13:39 < zyp> the point is that cortex-m7 has 64-bit wide data buses while other cortex-m variants only got 32-bit wide buses
2022-01-04T12:13:59 < zyp> and to make use of 64-bit wide buses, you also need 64-bit wide memories and stuff
2022-01-04T12:14:27 < zyp> but you still got 32-bit wide stuff in the system, so you end up with both a 64-bit bus matrix and a 32-bit bus matrix
2022-01-04T12:15:06 < zyp> on a cortex-m4 you don't have the 64-bit matrix; everything including the cpu is connected to the 32-bit matrix
2022-01-04T12:17:30 < drzacek> a noob question, but why didn't they just did a native 64-bit only chip, and just skipped the 32bit part completely?
2022-01-04T12:17:39 < drzacek> for simplifying hardware and software?
2022-01-04T12:17:53 < ventYl_> ARMv6M is 32bit platform
2022-01-04T12:18:11 < ventYl_> IDK if there is any 64bit native embedded arch already
2022-01-04T12:18:18 < zyp> drzacek, because that would require redesigning all peripherals
2022-01-04T12:18:44 < zyp> or not necessarily, you could just extend each register to 64 bits
2022-01-04T12:19:04 < zyp> but it'd still require every single peripheral driver to account for the address difference
2022-01-04T12:19:32 < ventYl_> why so? you could still access 32bit registers from within 64 bit CPU probably
2022-01-04T12:19:43 < ventYl_> that wouldn't trigger unaligned access
2022-01-04T12:20:09 < zyp> like, if you have UART1_SR at 0x40000000 and UART1_CR at 0x40000004 on a 32-bit wide bus, the latter would be at 0x40000008 on a 64-bit wide bus
2022-01-04T12:20:46 < ventYl_> ah, ARM buses use 32-bit quantitites as addressing granularity?
2022-01-04T12:21:07 < drzacek> shouldn't this then require new BASE address, and all other should be relative to the base address?
2022-01-04T12:21:20 < zyp> no
2022-01-04T12:21:33 < drzacek> ah well
2022-01-04T12:21:43 < drzacek> guess I'm reading it whole then. see you in few months
2022-01-04T12:21:52 < zyp> the address increment per word is equal to the bus width in bytes
2022-01-04T12:22:24 < zyp> ventYl_, this is not ARM specific, every memory bus works in that manner
2022-01-04T12:24:43 < zyp> when you have a 32-bit memory space, i.e. 4 gigabytes, a 32-bit wide bus would see it as 30 bits of address, four bits of byte selects and 32 bits of data
2022-01-04T12:25:05 < zyp> a 64-bit wide bus sees the same address space as 29 bits of address, eight bits of byte selects and 64 bits of data
2022-01-04T12:25:05 -!- yukam [~yukam@user/yukam] has quit [Ping timeout: 250 seconds]
2022-01-04T12:25:58 < ventYl_> zyp: right, i didn't realize this. i somehow assumed that you can access smaller quantities as some registers can be accesses as bytes / words and read/write size has meaning
2022-01-04T12:26:25 < ventYl_> so I expected that even if registers were packed 32bits apart, peripheral would be able to realize that you are reading just part of it
2022-01-04T12:27:26 < zyp> ventYl_, that's what the bridge between the AXI bus matrix and the AHB bus matrix does :)
2022-01-04T12:28:12 < ventYl_> I somehow expected it is possible to perform that bridge-less
2022-01-04T12:28:23 < ventYl_> or with very little of added circuitry
2022-01-04T12:28:52 < ventYl_> which probably is, but that would fall into "redesign all peripherals" category
2022-01-04T12:29:48 < zyp> well, you could make the peripheral bus 64-bits wide and map two registers to each word and look at the byte selects every time they are accessed
2022-01-04T12:30:34 < zyp> but do you really think it's easier to do that for every single pair of registers, rather than doing it once for the entire 32-bit bus? :)
2022-01-04T12:31:15 < drzacek> I always assumed that addresses are in bytes
2022-01-04T12:31:39 < zyp> no, they are always in bus words
2022-01-04T12:31:58 < ventYl_> why each pair of registers? you could add it once per peripheral, decode that one single bit and simply provide it as an additional addressing information
2022-01-04T12:32:22 < zyp> yeah, sure, that's what a bus bridge is
2022-01-04T12:32:28 < ventYl_> drzacek: it may look like that because x86 allows for "unaligned" access
2022-01-04T12:32:49 < ventYl_> so you can access 4-byte quantity aligned at 2-byte boundary without causing major disaster
2022-01-04T12:32:53 < zyp> ventYl_, but why put one in front of each peripheral instead of one in front of the entire peripheral bus? :)
2022-01-04T12:33:01 < ventYl_> historically ARM didn't allow that, dunno about current platforms
2022-01-04T12:33:03 < drzacek> I worked on some project that used ISA bus, and I think that was 8bit, so maybethats why
2022-01-04T12:33:05 -!- yukam [~yukam@user/yukam] has joined ##stm32
2022-01-04T12:33:07 < ventYl_> zyp: yeah, that's valid point
2022-01-04T12:33:44 < ventYl_> IIRC ISA can be both 8- and 16-bit
2022-01-04T12:34:07 < zyp> I think cortex-m0 disallows unaligned accesses, but m3 and up allows it unless configured not to
2022-01-04T12:34:36 < drzacek> maybe. that thing is ancient from my perspective, what I did in that project didn't touched the ISA part, but saw the address definitions everywhere
2022-01-04T12:34:50 < ventYl_> anyway it is not a good idea to do that because it implies performance penalty
2022-01-04T12:34:55 < zyp> the thing about unaligned accesses is that they are just translated into two actual accesses
2022-01-04T12:35:04 < ventYl_> as CPU needs to do two reads / writes
2022-01-04T12:35:45 < ventYl_> particularly funny solution to unaligned accesses was used in AltiVec in PPC
2022-01-04T12:36:07 < ventYl_> AltiVec explicitly disallows unaligned accesses, but does not except when you try to do one
2022-01-04T12:36:17 < ventYl_> it simply doesn't decode low 7 bits of vector address
2022-01-04T12:36:23 < zyp> if you're writing (*uint32_t)0x3 = 0xaabbccdd, the cpu will be writing 0x0 = 0xddzzzzzz and 0x04 = 0xzzaabbcc
2022-01-04T12:36:31 < ventYl_> hm, 3 bits or so
2022-01-04T12:37:01 < zyp> yeah
2022-01-04T12:38:03 < zyp> when you've got an alignment requirement on an address, the bottom n bits are required to be 0 and can be assumed to, in which case you can use them for other information instead
2022-01-04T12:38:38 < ventYl_> such as ARM / Thumb
2022-01-04T12:38:39 < zyp> arm code adresses are 16-bit aligned, so the bottom bit is used to signal whether it's arm mode or thumb mode code
2022-01-04T12:38:42 < zyp> yup
2022-01-04T12:39:22 < ventYl_> PPC didn't make any particular use of that bits. it simply ignored them completely
2022-01-04T12:39:26 < zyp> and x86 page tables
2022-01-04T12:39:50 < ventYl_> meh... x86
2022-01-04T12:40:04 < zyp> 4k page addrs have 12 reserved bits in the bottom, which is used for metadata in the page tables
2022-01-04T12:40:28 < zyp> arm probably does the same, but I've never worked with the arm mmu :)
2022-01-04T12:40:42 < ventYl_> me neither
2022-01-04T12:40:57 < ventYl_> but MPU has not the most fortunate design i've ever seen
2022-01-04T12:42:52 < ventYl_> on the other hand, x86 has the most unfortunate design possible
2022-01-04T12:42:56 < ventYl_> overally
2022-01-04T12:48:09 < Xogium> you guys never toyed with the stm32mp1 yet ?
2022-01-04T12:48:39 < zyp> no
2022-01-04T12:49:31 < Xogium> I'm toying with a few boards based on it right now, its fun
2022-01-04T12:50:09 < qyx> good to hear that
2022-01-04T12:50:20 < qyx> I am doing a mp1 board
2022-01-04T12:51:03 < Xogium> oh ?
2022-01-04T12:51:16 < Xogium> lots of folks jumped on the mp1 train
2022-01-04T12:51:34 < zyp> I've been meaning to play with it, but don't really have a specific use
2022-01-04T12:52:03 < zyp> though, for a cortex-a, it's not really all that impressive
2022-01-04T12:52:24 < Xogium> st made their own dev kit, octavo system made their SiP and dev kit and eval platform, so did seeed, myir, emcraft
2022-01-04T12:52:31 < Xogium> and now olimex
2022-01-04T12:52:47 < zyp> I've talked to people that considered it, but went with an arm64 part instead for better OS support
2022-01-04T12:52:53 < ventYl_> does it, at least, have impressive power consumption / DMIPS?
2022-01-04T12:53:43 < Xogium> I forget where those ratings are, but I reckon I seen it. I couldn't say what's impressive…
2022-01-04T12:53:59 < Xogium> but to me being open matters more than 64 bit especially for the project I'm doing
2022-01-04T12:54:07 < Xogium> 64 bit would be overkill
2022-01-04T12:54:38 < zyp> I think the point is that os support for arm64 is better than for arm32
2022-01-04T12:55:07 < Xogium> I mean, sure it's not the most badass SoC around, dual core at 800 mhz cpu max, but I don't need anything like a rpi4 lol
2022-01-04T12:55:33 < Xogium> ah… maybe ? I don't use distro, I make my own linux based system
2022-01-04T12:55:42 < Xogium> so I wouldn't really know about that
2022-01-04T12:55:59 < srk> it's because there are no good 32 bit arm systems to use in build farms
2022-01-04T12:56:07 < srk> i.e. something powerful with ecc memory
2022-01-04T12:56:14 < srk> 64 bit has plenty of server grade hw
2022-01-04T12:56:16 < Xogium> ah yeah, that would do it
2022-01-04T12:56:18 < srk> 32 is mostly mobile
2022-01-04T12:56:24 < qyx> it does have awesome st peripherals
2022-01-04T12:56:28 < qyx> and a M4 core
2022-01-04T12:56:45 < zyp> I did a work project last year with imx6ul, which stm32mp1 would almost have been a better fit for
2022-01-04T12:56:46 < Xogium> qyx: and a blob-less open hardware gpu ! ;) ok only on mp157
2022-01-04T12:57:05 < srk> you can do 32bit vm on 64bit machine but it has its own difficulties (weird compilation issues)
2022-01-04T12:57:10 < zyp> except the project called for dual ethernet ports, and stm32mp1 only got a single MAC
2022-01-04T12:57:32 < qyx> yeah for whatever reason I though it has two
2022-01-04T12:57:51 < qyx> so it solved my issue with big RJ45 on the front panel
2022-01-04T12:58:02 < Xogium> nah. Still… for a first time shot at the microprocessor world, I'd say st didn't do too bad
2022-01-04T12:58:03 < qyx> there will be none.
2022-01-04T12:58:08 < zyp> but being able to offload stuff to the M4 coprocessor would have been great, imx6ul doesn't have that
2022-01-04T12:58:08 < srk> imx6ul has two?
2022-01-04T12:58:16 < zyp> yeah
2022-01-04T12:58:47 < Xogium> zyp: yeah and the speed of that coprocessor is nothing to sneeze at either, 209 mhz
2022-01-04T12:59:29 < srk> interesting, my laptop with imx6q has only one "native" gbit port and the second one is 100mbit over usb
2022-01-04T13:00:39 < qyx> also it is a pity mp1 doesn't have pcie
2022-01-04T13:00:58 < qyx> at least a single lane
2022-01-04T13:01:13 < zyp> srk, the one I used got two MACs, but neither are gigabit
2022-01-04T13:01:32 < ventYl_> srk: what kind of laptop?
2022-01-04T13:01:52 < Xogium> qyx: hey, who knows, they might make another one like mp2 ;)
2022-01-04T13:02:31 < ventYl_> mp3 and mp5 would probably be left out for obvious reasons
2022-01-04T13:03:39 < Xogium> hah
2022-01-04T13:03:43 < Xogium> probably
2022-01-04T13:03:51 < Xogium> especially mp5 hehe
2022-01-04T13:04:29 < ventYl_> you don't want to offend anyone by your model number, do you?
2022-01-04T13:04:51 < ventYl_> i once read how ericsson chose their model numbers in order not to offend anyone
2022-01-04T13:05:29 < ventYl_> so T10 and T18 weren't just some random numbers, they simply didn't offend enough people globally
2022-01-04T13:05:34 < Steffanx> That's impossible. People will be offended no matter what
2022-01-04T13:05:41 < Xogium> I suppose not… though I personally wouldn't care much about it :D
2022-01-04T13:06:04 < Xogium> I mean honestly its just a model number… who cares
2022-01-04T13:06:07 < Steffanx> Get enough twatter exposure and enough people will be offended
2022-01-04T13:06:15 < ventYl_> 38 probably offended enough people, so they initially named it T36, then changed to T39
2022-01-04T13:06:43 < srk> ventYl_: novena
2022-01-04T13:06:43 < ventYl_> change was probably due to the fact that they found someone additional being offended by it
2022-01-04T13:08:01 < Xogium> srk: oh nice, one of my friends has a novena too
2022-01-04T13:08:18 < Xogium> shame it was all but abandoned
2022-01-04T13:08:33 < ventYl_> srk: is it designed to be used as replacement for existing chassis?
2022-01-04T13:12:51 < ventYl_> 32bit platform probably has no future due to reasons mentioned above
2022-01-04T13:14:59 < srk> ventYl_: nope, it has its own weird chassis :D
2022-01-04T13:15:29 < srk> Xogium: pretty much and there are still some patches missing from mainline so when you boot linux on it you won't get graphics/sound..
2022-01-04T13:18:11 < Xogium> sucks
2022-01-04T13:18:54 < ventYl_> i have pinebook, which is as good as you can go with guerilla electronics design
2022-01-04T13:19:04 < Xogium> say what you want about 32 bit and st, but they made a commitment to provide the mp1 until at least 2036, 2 years before the year 2038 bug
2022-01-04T13:20:38 < ventYl_> Xogium: well, it will have it's uses
2022-01-04T13:21:15 < Xogium> sure
2022-01-04T13:21:28 < Xogium> like for my 24/7 irc client :D
2022-01-04T13:21:36 < Xogium> using the board from seeed for that one
2022-01-04T13:21:44 < ventYl_> my 24/7 irc client used to run on my wifi router
2022-01-04T13:22:07 < ventYl_> then I installed stock firmware back in. now I regret it, but I am also lazy to install Linux back in
2022-01-04T13:22:16 < Xogium> haha
2022-01-04T13:30:26 < ventYl_> just as RT OSes are evolving, I'd expect that there will be lower need for running linux on embedded systems
2022-01-04T13:30:40 < ventYl_> as it carries a lot of unused stuff with itself
2022-01-04T13:31:44 < Xogium> yeah… hard to say
2022-01-04T13:32:38 < Xogium> I'd sure not run a full distro on my boards, these days. I have nothing against distros, but I prefer customisation, and knowing exactly how every piece of software I add to my rootfs is compiled and with what settings
2022-01-04T13:32:55 < Xogium> and just what I actually require
2022-01-04T13:34:34 < Xogium> buildroot is a bit like linux from scratch on stereoid, it uses kconfig and makefiles to build the system for you exactly how you selected things, from bootloader to userspace
2022-01-04T13:34:46 < Xogium> it's my way of having fun with linux these days :p
2022-01-04T13:35:34 < ventYl_> buildroot is probably just an evolution of openembedded
2022-01-04T13:35:37 < ventYl_> or maybe that's yocto
2022-01-04T13:35:52 < ventYl_> i've been playing with it like 10+ years ago when I tried to pack linux into my iPaq
2022-01-04T13:37:30 < Xogium> yep OE is yocto
2022-01-04T13:37:41 < Xogium> and has a down right mean learning curve to the point I never learned it
2022-01-04T13:37:43 < PaulFertser> No, yocto is OE plus some layers.
2022-01-04T13:37:45 < srk> hehe, I use novena for irc client and ircbot as it consumes close to nothing with just passive cooling
2022-01-04T13:37:47 < PaulFertser> buildroot is unrelated.
2022-01-04T13:38:08 < PaulFertser> iPaq was likely Angstrom distro based on OE.
2022-01-04T13:38:18 < ventYl_> yeah
2022-01-04T13:38:45 < PaulFertser> OpenWrt is also kind of buildroot-based but very heavily reworked.
2022-01-04T13:38:53 < ventYl_> it was something like OE + Qt + OPIE. but IDK where Qt and OPIE came from
2022-01-04T13:39:04 < Xogium> fun fact, OpenWRT was forked from buildroot almost 15 years ago… And these days  it is barely recognizable
2022-01-04T13:39:26 < Xogium> oww, PaulFertser beat me to it
2022-01-04T13:41:39 < Xogium> but OpenWRT's build system is so different that I decided to stick to buildroot ;)

2022-01-04T14:36:38 < kakium69> you don't need to add ircs
2022-01-04T14:36:57 < ventYl_> "I don't know what IRC is but it looks similar to IBM, so this one definitely knows IBM Tivoli"
2022-01-04T14:36:58 < kakium69> your skillset is already impressive
2022-01-04T14:37:25 < kakium69> if you add IRC it only can affect negativelly

2022-01-04T14:40:30 < qyx> old boss said there is nothing on irc, I should do some work or attend some courses instead
2022-01-04T14:40:57 < qyx> but he didn't know ##stm32 is ful of irc professionals
2022-01-04T14:41:23 < kakium69> and that is when you fired him?
2022-01-04T14:41:40 < qyx> he also said I should not build my house and do work for him instead
2022-01-04T14:41:56 < qyx> thats when I fired him
2022-01-04T14:42:31 < jadew> there are IRC professionals for sure
2022-01-04T14:42:35 < jadew> we're just not it
2022-01-04T14:42:41 < qyx> he was fan of low paid workers to do manual stuff
2022-01-04T14:43:35 < jadew> I think anyone can be a fan of that
2022-01-04T14:44:37 < qyx> when I left he said I was not good enough and it wasn't a big loss
2022-01-04T14:45:15 < jadew> lol
2022-01-04T14:45:30 < qyx> he said that when anyone left
2022-01-04T14:45:42 < jadew> what a jerk
2022-01-04T14:45:54 < jadew> did you leave him a review on specialized sites?
2022-01-04T14:45:57 < qyx> I would say a complicated personality
2022-01-04T14:46:01 < jadew> "asshole of a human"

2022-01-04T15:29:34 < kakium69> question
2022-01-04T15:29:46 < kakium69> I'm low on leaded solders
2022-01-04T15:30:06 < kakium69> I think I want to buy multiple types
2022-01-04T15:30:15 < kakium69> should I.. and which ones?
2022-01-04T15:31:59 < kakium69> Sn62Pb37Cu1?
2022-01-04T15:32:28 < mawk> is it eutectic?
2022-01-04T15:32:31 < mawk> that's all that matters
2022-01-04T15:32:40 < mawk> and rosin core maybe but I don't find it very useful I use flux always
2022-01-04T15:32:47 < jadew> why would you use leaded solder these days?
2022-01-04T15:33:08 < mawk> because it flows like butter on a toast
2022-01-04T15:33:21 < mawk> and lower temp
2022-01-04T15:33:30 < jadew> it does, but if you end up in a situation where you need to use leadfree, then it's very difficult to keep things separate
2022-01-04T15:34:13 < Steffanx> Unlikely I will find myself in need of lead free
2022-01-04T15:34:25 < jadew> I ended up thrashing lots of stuff because it was either leaded or I didn't know if it was leaded or lead free
2022-01-04T15:34:42 < mawk> you don't have your portable xray fluorescence spectrum analyzer?
2022-01-04T15:34:50 < mawk> everybody has one
2022-01-04T15:35:02 < Steffanx> Always use flux.. flux is the most awful crap
2022-01-04T15:35:11 < kakium69> I don't need to rohs my shits
2022-01-04T15:35:18 < jadew> I left it in my calibration laboratory
2022-01-04T15:35:51 < jadew> yeah, that's how I decided to get leaded solder too
2022-01-04T15:36:14 < Laurenceb> reeeee hyperloop I2C sensors lock up during immunity testing
2022-01-04T15:36:18 < Laurenceb> epin fail
2022-01-04T15:36:47 < jadew> communication failure or die failure?
2022-01-04T15:37:38 < kakium69> Laurenceb: it's on you?
2022-01-04T15:37:56 < Laurenceb> looks like some sort of onboard lockup
2022-01-04T15:38:10 < Laurenceb> data stops updating but sensor talks ok on the bus
2022-01-04T15:38:29 < jadew> so it's not the sensor
2022-01-04T15:38:35 < jadew> it's something YOU did :P
2022-01-04T15:39:31 < Laurenceb> lol
2022-01-04T15:42:51 < PaulFertser> Laurenceb: immunity to what?
2022-01-04T15:43:00 < Laurenceb> injected rf
2022-01-04T15:43:23 < PaulFertser> Laurenceb: reliably? or like one in 100?
2022-01-04T15:43:25 < jadew> on the power line?
2022-01-04T15:43:29 < Laurenceb> yeah
2022-01-04T15:43:37 < jadew> so you need a better choke
2022-01-04T15:43:46 < PaulFertser> Does it start updating after RF stops?
2022-01-04T15:43:49 < Laurenceb> PaulFertser: only seen a single lock up so far
2022-01-04T15:43:57 < Laurenceb> PaulFertser: no
2022-01-04T15:44:18 < Laurenceb> it needs to be power cycled, and we dont have auto power cycle support on the hardware
2022-01-04T15:44:34 < jadew> you don't have a watchdog?
2022-01-04T15:44:52 < jadew> what kind of unsafe hyperloop shit are you making?
2022-01-04T15:45:33 < PaulFertser> Guess Laurenceb means the sensor itself enters some strange state which can be recovered only by power-cycling of the sensor, right?
2022-01-04T15:45:41 < Laurenceb> yeah
2022-01-04T15:45:42 < jadew> no
2022-01-04T15:45:44 < Laurenceb> https://www.renesas.com/us/en/document/dst/zsc31014-datasheet?r=179821
2022-01-04T15:45:49 < Laurenceb> ^its one of these
2022-01-04T15:46:01 < jadew> but you said the sensor talks fine on the bus
2022-01-04T15:46:04 < Laurenceb> sensor is setting an overrun error flag
2022-01-04T15:46:19 < jadew> overrun - data not being ACKed?
2022-01-04T15:46:23 < Laurenceb> yeah it talks fine, but its as if the internal oscillator stops or something
2022-01-04T15:46:36 < Laurenceb> data is acked fine, we have logic analyser on the bus
2022-01-04T15:46:48 < jadew> ah, ok
2022-01-04T15:47:16 < Laurenceb> I wonder if it somehow entered eeprom programming mode
2022-01-04T15:47:32 < Laurenceb> we haven't been able to replicate, tried for a few hours so far
2022-01-04T15:48:05 < jadew> ignore that time when it failed and say it did fine during testing :P
2022-01-04T15:48:34 < PaulFertser> Laurenceb: have you tried putting it into sleep mode and then back in that state?
2022-01-04T15:49:01 < Laurenceb> my understanding is that it should auto sleep
2022-01-04T15:49:02 < jadew> if you can't replicate it, it might have been something else - keep that in mind too
2022-01-04T15:49:20 < PaulFertser> It says it has two distinct modes.
2022-01-04T15:49:20 < Laurenceb> we have tried leaving it for a while, but the problem remained until it was power cycled
2022-01-04T15:49:37 < Laurenceb> jadew: we saw this for 45minutes with logic analyser on
2022-01-04T15:49:45 < Laurenceb> only went when we power cycled the sensor
2022-01-04T15:50:16 < jadew> you said there was a flag said - what does the documentation say about it?
2022-01-04T15:50:30 < jadew> look into what might have caused it and try to address that
2022-01-04T15:50:39 < jadew> also take into account that you might need some redundancy there
2022-01-04T15:50:51 < jadew> sensor fails? use a different one + reboot the current one
2022-01-04T15:51:58 < jadew> overrun issues (if that's what it is) generally indicate that data in a buffer has not been consumed in a timely fashion
2022-01-04T15:52:11 < jadew> maybe your MCU or whatever consumes that data got stuck for a little
2022-01-04T15:52:21 < jadew> did you have the analyzer logging all the data all the time?
2022-01-04T15:52:52 < PaulFertser> The datasheet doesn't mention any overrun flags.
2022-01-04T15:53:52 < Laurenceb> oops wrong sensor
2022-01-04T15:54:00 < Laurenceb> this is HS3003 that locked up
2022-01-04T15:54:12 < Laurenceb> that ZSC is also on the bus but was working ok
2022-01-04T15:56:17 < PaulFertser> Laurenceb: were you able to read ID number?
2022-01-04T15:56:30 < jadew> so you're getting stale data?
2022-01-04T15:56:31 < Laurenceb> we didnt try :(
2022-01-04T15:56:32 < jadew> or what?
2022-01-04T15:56:43 < Laurenceb> jadew: yeah it just sends the same data
2022-01-04T15:56:56 < jadew> and the status bits show stale data?
2022-01-04T15:56:58 < PaulFertser> It says it has "stale" bit but not overrun.
2022-01-04T15:57:07 < jadew> yeah, that's all it has
2022-01-04T15:57:10 < jadew> stale or fine
2022-01-04T15:57:25 < jadew> if it's all stale, then the sensor probably ends up in a weird state
2022-01-04T15:57:52 < Laurenceb> aiui HS3003 is a variant of that ZSC ic
2022-01-04T15:58:07 < jadew> so it looks like you first send a measurement request and then you read the data
2022-01-04T15:58:14 < jadew> and you know if it's good or not based on the status bit
2022-01-04T15:58:27 < jadew> like... that's how you know when it's ready
2022-01-04T15:59:03 < jadew> did you check if the timing requirements were being violated
2022-01-04T15:59:05 < jadew> ?
2022-01-04T15:59:05 < xnand> ?<factoid> to query, ?<factoid>=value to set, ?<factoid>-forget to unset

2022-01-04T15:59:38 < jadew> also, it's safer
2022-01-04T16:00:14 < jadew> you prick your finger with lead free you're odds of going bananas are significantly lower
2022-01-04T16:01:00 < jadew> Laurenceb, did you make sure that the fault was not a higher frequency reference clock?
2022-01-04T16:01:02 <@karlp> and "needing to" is pretttttty fucking small group these days, so I'm going to err on "you're wrong" to most people who claim they "need" it as well.
2022-01-04T16:01:19 < jadew> which could in turn violate the timing requirements of the sensor?
2022-01-04T16:01:42 < Laurenceb> hmm that woudn't explain why the rf breaks it
2022-01-04T16:02:04 < jadew> the injected RF could disturb the oscillator and switch it to a hamonic for example
2022-01-04T16:02:33 < mawk> karlp: I have a shitty iron that doesn't go high in temp
2022-01-04T16:02:40 < jadew> it's hard to tell without knowing what you have there
2022-01-04T16:03:02 <@karlp> using lead for that excuse is moronic.
2022-01-04T16:03:02 < jadew> mawk, get one of those 200W chinese stations
2022-01-04T16:03:06 < Laurenceb> I dunno...
2022-01-04T16:03:08 < mawk> lol
2022-01-04T16:03:12 <@karlp> you obviously have lead poisoning.
2022-01-04T16:03:23 < mawk> elemental lead is pretty okay
2022-01-04T16:03:28 < mawk> the bioavailability isn't that high
2022-01-04T16:03:36 < mawk> and it tastes sweet
2022-01-04T16:03:36 < Laurenceb> but if the sensor was in command mode it wouldnt be expected to send back any data at all...
2022-01-04T16:03:40 <@karlp> you do you, but I'm sticking with "you're a moron" :)
2022-01-04T16:05:37 < jadew> Laurenceb, what's the resolution is being used at?
2022-01-04T16:05:56 < Laurenceb> jadew: full resolution, 14bit iirc
2022-01-04T16:06:06 < jadew> so look at the LA data
2022-01-04T16:06:25 < jadew> and see if there's a 34 ms delay between the request for the measurement and the reading of the data
2022-01-04T16:06:46 < jadew> (in the LA data you collected during failure)
2022-01-04T16:07:00 < jadew> if there is, then what I just suggested is not the issue
2022-01-04T16:07:51 < Laurenceb> yeah thats about 60ms delay
2022-01-04T16:08:36 < jadew> time to contact renesas
2022-01-04T16:08:42 < BrainDamage> karlp: lead free solder is more harmful for personal (re)work than leaded
2022-01-04T16:09:00 < jadew> not if you extract the fumes
2022-01-04T16:09:29 < BrainDamage> the higher temps and stonger / higher amount of flux are the danger for the worker
2022-01-04T16:09:54 <@karlp> what are teh higher temps causing?
2022-01-04T16:10:04 <@karlp> I'll accept your flux argumentas a "maybe" but higher temps? what?

2022-01-04T16:11:37 < Laurenceb> we have a load of boards, and they dont have any facility to power cycle the sensors :(
2022-01-04T16:11:55 < jadew> next revision then :)
2022-01-04T16:12:27 < jadew> you could try changing settings to yank the sensor out of that state
2022-01-04T16:12:37 < jadew> but if you can't replicate the issue, it's going to be difficult to test
2022-01-04T16:12:54 < Laurenceb> I was think it couldnt be in command mode as it sends out sensor data, but maybe the internal logic just resends the data from buffer registers or something
2022-01-04T16:13:22 < BrainDamage> karlp: they make the flux to boil more
2022-01-04T16:14:29 < jadew> I think google has dumbed the image search on purpose

2022-01-04T16:25:04 <@karlp> BrainDamage: so what's in all "flux" that's the problem, and why is lead better?
2022-01-04T16:25:06 < mawk> nothing wrong with that
2022-01-04T16:25:10 < jadew> it was a joke... because you assumed I don't know what safe search is :)
2022-01-04T16:25:22 < mawk> a
2022-01-04T16:25:23 <@karlp> are you just basing it on the volume of rework that individuals are ever likely to do?
2022-01-04T16:25:34 <@karlp> surely that should also apply to the flux?
2022-01-04T16:26:04 < BrainDamage> karlp: because lower temps produce less oxidation and require weaker fluxes
2022-01-04T16:26:06 < jadew> karlp, I hear lead free flux is more corrosive and generally a nastier substance
2022-01-04T16:27:08 < BrainDamage> karlp: then again, it's generally a minor concern
2022-01-04T16:28:54 <@karlp> well, I'm sticking with less lead around, more better, 
2022-01-04T16:30:28 < BrainDamage> yeah, no reason to go hardly for one or the other nowdays
2022-01-04T16:30:31 < Xogium> ok… probably easy question… I hope. If I want to use a piezo element to sense knocks with a board
2022-01-04T16:30:53 < Xogium> what does determine the resistor I'd need to put to avoid damaging the analog pin of the oard ?
2022-01-04T16:31:56 < Xogium> only tutorial I find for knock sensing specify 1 megohm
2022-01-04T16:32:36 < ventYl_> good question, CC me if you find it. in long run, I may need that information too
2022-01-04T16:32:39 < Xogium> but how do they even determine this
2022-01-04T16:32:51 < ventYl_> isn't there some voltage / pressure figure given?
2022-01-04T16:33:00 < Xogium> I'm not sure
2022-01-04T16:33:11 < ventYl_> or more likely voltage / dp
2022-01-04T16:33:19 < Laurenceb> lol Elisabeth Holmes got pwnd
2022-01-04T16:33:20 < Xogium> only tutorial I found is on arduino.cc mind you, soooo… make of that what you want lol
2022-01-04T16:33:26 < Xogium> I wouldn't trust them
2022-01-04T16:33:50 < ventYl_> is it like with this specific piezo and this atmega you need 1megaohm resistor and it will be mostly fine?
2022-01-04T16:34:24 < Xogium> https://www.arduino.cc/en/pmwiki.php ?n=Tutorial/Knock
2022-01-04T16:34:31 < Xogium> oops
2022-01-04T16:34:34 < Xogium> https://www.arduino.cc/en/pmwiki.php?n=Tutorial/Knock
2022-01-04T16:34:36 < Xogium> better
2022-01-04T16:37:01 < ventYl_> hm, in that arrangement it is probably used as "current measurement"
2022-01-04T16:38:15 < Xogium> they claim it is to protect the analog input
2022-01-04T16:39:04 < ventYl_> yeah, probably in the way how measurement is done. you can't measure voltage directly, thus you measure it as voltage drop on very large resistor
2022-01-04T16:39:30 < Xogium> I'm still confused
2022-01-04T16:39:36 < ventYl_> that resistor shorts piezo element effectively
2022-01-04T16:39:48 < Xogium> how would that be safe ? How do you know if it's enough or too much ?
2022-01-04T16:40:34 < BrainDamage> the answer is; you don't
2022-01-04T16:40:55 < ventYl_> well principially you need to know voltage / dp as I said above. and you need to know internal resistance. IDK if any of these is specified anywhere
2022-01-04T16:41:01 < ventYl_> I'd assume that former is, latter is not.
2022-01-04T16:41:21 < ventYl_> unintuitively, smaller resistor values here would be safer, I expect
2022-01-04T16:41:30 < BrainDamage> correct
2022-01-04T16:41:41 < ventYl_> but your measurement resolution would also suffer
2022-01-04T16:41:58 < ventYl_> it also depends on how strong knocks you want to measure
2022-01-04T16:42:03 < BrainDamage> if you really want to protect the pin, add a tvs diode
2022-01-04T16:42:08 < ventYl_> yeah
2022-01-04T16:43:00 < Xogium> right… that's above my head for now
2022-01-04T16:43:03 < BrainDamage> the resistor scales down the signal output, the problem is that you have no idea about the scaling factor
2022-01-04T16:43:45 < ventYl_> Xogium: do you know how current flow is measured using ballast resistors of 0R1 or smaller values?
2022-01-04T16:43:48 < ventYl_> this is the same
2022-01-04T16:44:08 < ventYl_> just piezo is very soft power source, so you have to use large resistor values to generate barely any detectable voltage
2022-01-04T16:44:10 < BrainDamage> it depends on too many things, force, piezo characteristics, even how you mount will change the output
2022-01-04T16:44:49 < Xogium> I have 0 knowledge of electricity or anything yet
2022-01-04T16:45:27 < ventYl_> Xogium: well then start with current measurement. it will provide you with basics without being confused by the piezo part for a while. you can drop the piezo characteristics in later

2022-01-04T16:56:22 < Laurenceb> hmm I think I spotted something: stale data bit gets intermittently set during the immunity testing
2022-01-04T16:56:45 < Laurenceb> stale data bit gets set by POR being triggered, and POR threshold is 2.5V
2022-01-04T16:56:58 < Laurenceb> I think POR is getting triggered by the rf
2022-01-04T16:58:50 < Laurenceb> according to the ZSC31014 datasheet (assuming HS3003 is basically the same), it should wait 10ms to enter normal mode after POR, so if it gets the wakeup (I2C write) followed by corrupted data (due to rf), maybe it never enters command mode or normal mode
2022-01-04T16:59:00 < Laurenceb> just sits there waiting for more data
2022-01-04T17:00:47 <@karlp> hrm, jpa- yourplain resistor divider for Vgs protection looks simpler in every way, and certainly works for my usecases
2022-01-04T17:00:52 <@karlp> fuck zeners you're dead to me!

2022-01-04T22:16:57 < fenugrec> I found this rubber plug / grommet at the back of my workbench https://ibb.co/7r7CcqR . Been looking at it for 10 minutes and can't figure out where it's from
2022-01-04T22:17:31 < catphish> finished the software for my BMS today, figured out how to have the RP2040 shut down all clocks apart from a single PLL and output that clock on a pin to clock the CAN controller, so CAN can wake it up again :)
2022-01-04T22:18:21 < catphish> on the other hand, i'm an idiot and forgot to wire the sleep pin of the CAN transceiver to the MCU, so it can't go into low power RX-only mode, and wastes 2.5mA :(
2022-01-04T22:29:54 < qyx> Xogium: whats the stm32mp1 board you have?
2022-01-04T22:30:26 < qyx> Xogium: is there any chance you could measure its power consumption while being idle (without ethernet and usb connected)
2022-01-04T22:37:36 < Xogium> qyx: currently have the seeed studio stm32mp157c odyssey board
2022-01-04T22:38:07 < Xogium> but planning on toying with the one from olimex and the official dev kit from st as well
2022-01-04T22:38:35 < ventYl_> catphish: do you have CAN transciever, or CAN SBC there?
2022-01-04T22:39:01 < Xogium> I'll try and ask my friend if he could do that test, since I don't have a multimeter or any way to measure power draw

2022-01-04T22:40:12 < qyx> This application note provides power consumption values on various use cases measured on a STM32MP157C device
2022-01-04T22:40:15 < qyx> mounted on a STM32MP157C-EV1 evaluation board and running on STM32 MPU OpenSTLinux Distribution.

2022-01-04T22:41:08 < catphish> MCP2515
2022-01-04T22:41:43 < catphish> i chose to clock it from the MCU's PLL to simplify the design
2022-01-04T22:41:55 < Xogium> qyx: yeah so efectively you would evaluate the power draw of the whole board not just the SoC… if I understand right
2022-01-04T22:42:29 < ventYl_> ah, the sleep goes other way around
2022-01-04T22:43:57 < Xogium> qyx: actually I'm dumb, let me check what I noted down with my friend when we did power draw tests on  battery last year
2022-01-04T22:44:12 < Xogium> I entirely forgot about those notes

2022-01-04T22:47:03 < Xogium> qyx: so with stuff like serial console and wifi in use it was about 350 mA. With neither, it drew about 280 mA
2022-01-04T22:47:22 < Xogium> qyx: this is without any kind of low power mode engaged, or cpu frequency scaling or anything of the sort
2022-01-04T22:48:13 < qyx> 280 mA at 5V?

2022-01-04T22:50:41 < Xogium> like, I'm guessing linux probably activated the m4 even if it was not used, and possibly other peripherals. Usb was possibly not turned off with anything plugged in, due to how seeed made their u-boot simply toggle a gpio
2022-01-04T22:51:04 < Xogium> for vbus and the likes
2022-01-04T22:52:31 < Xogium> the why I want to get st's dev kit for that board is, software should be much better handled than seeed ever did, and we'd get the very latest improvements from st
2022-01-04T22:52:58 < Xogium> seeed made an old by now debian 10 image, threw it out there and never bothered with updating bootloader and kernel since 2019
2022-01-04T22:53:18 < Xogium> typical vendor crap
2022-01-04T22:54:16 < ventYl_> i read typical vector crap

2022-01-04T23:12:04 < steve__> haven't had to purchase anything in a while, now I can't find much on the major distributors.  Is there a resource yall use to find stock for STM32 or equivalent?

2022-01-04T23:17:49 <@karlp> use renode, develop your sw, be ready to launch with flawless sw when the situation resolves...
2022-01-04T23:17:58 < qyx> :D
2022-01-04T23:18:16 < qyx> have you ever seen a flawless sw
2022-01-04T23:21:43 <@karlp> well, most people rush to hardware? :)
2022-01-04T23:22:38 < steve__> I think my sw is pretty good lol.  I've abstracted all of the application, but of course any part swap requires new BSP/HAL layer.  yeah stm32 is hard to find, I'm seeing more renesas, PIC, LPC.  Need a 100 pieces in a few months.  I think the reality is I'll have to maintain multiple designs and do small batches with different part set.
2022-01-04T23:23:34 < jpa-> i'm using gd32 now

2022-01-05T12:37:53 <@karlp> it's ok, it's commented out.
2022-01-05T12:38:27 < jadew> heh
2022-01-05T12:39:32 < jadew> zyp, it would be something like // The reason is like this is because X and Y. If this changes we should revisit the implementation.
2022-01-05T12:39:34 < jadew> something like that
2022-01-05T12:39:46 < jadew> *it is like

2022-01-05T12:44:04 < ventYl_> jadew: the codebase I am working on right now is of kind, where if you find literally any comment, it means, the code was considered so trashy by the autor, he felt the obligation to explain what is going on there
2022-01-05T12:44:12 < jadew> *-I (one of them)
2022-01-05T12:44:35 < ventYl_> and there are either no comments, or there are 10-line-long blocks every 5 or so lines
2022-01-05T12:45:23 < jadew> so maybe it's not that it's trashy, but he assumes everything else is self obvious, but those things are complex?
2022-01-05T12:45:52 < ventYl_> it is trashy
2022-01-05T12:46:24 < ventYl_> it is full of hacks, bad design decisions which were rather hacked around rather than being refactored and abuses Qt

2022-01-05T13:24:38 < Xogium> karlp: I don't know… in france we use to have no custom fees for stuff bought with jlcpcb, but have 50 euros of fees for pcbway
2022-01-05T13:25:14 < jadew> yeah, I think that's been removed all across europe
2022-01-05T13:25:22 < jadew> there's no threshold now, everything gets taxed
2022-01-05T13:26:04 <@karlp> I don't know how pcbway would have been different honestly, it certainly wouldn't have been any different here.
2022-01-05T13:26:37 <@karlp> anyway, protolab that we used once like 10 years ago wanted ~300 euro, and it's now getting shipped for 18euro :)
2022-01-05T13:26:52 <@karlp> one local, one internet magic, we'll see who can really offer better service :)
2022-01-05T13:29:00 < ventYl_> i guess that with iceland-local service, the issues are fixed expenses vs. relatively small market
2022-01-05T13:34:26 <@karlp> presumably. the local guys are definitely part time nerds though I believe.  he replied with a university email address, and they offer phone support til 10pm, and mostly have a shop selling parts for hobbyists.
2022-01-05T13:34:32 <@karlp> we'll see what the print is like
2022-01-05T13:34:51 <@karlp> they definitely have company services for prototyping though, or at least claim to, all direct billed

2022-01-05T13:51:44 < jadew> that power supply looks really nice
2022-01-05T13:52:34 < jadew> the west is fucked
2022-01-05T13:53:00 < Steffanx> Moneyed westerners buy proper tools
2022-01-05T13:53:34 < jadew> yeah, but China seems to slowly server the proper tools market too
2022-01-05T13:53:51 < jadew> and they have the advantage of being in China over everyone else
2022-01-05T13:54:38 < jadew> I guess they always had the option to innovate, but it was easier to steal or make the bare minimum
2022-01-05T13:54:52 < ventYl_> karlp: it looks like some kind of battery monitor for cellphone batteries
2022-01-05T13:55:24 < jadew> that was sort of annoying for the rest of the world, but now if the chinese are putting out decent products on the market, then it's going to be very difficult to compete
2022-01-05T13:56:55 < jadew> they have siglent, rigol and now all these smaller companies, slowly nibbling out ground from under everyone else
2022-01-05T13:57:18 <@karlp> ventYl_: that's what I guessed, yeah, just never seen them before.  looks like a bench supply, that "just happens" to also come with some special support for doing some assembly line testing work.
2022-01-05T13:58:52 < jadew> the USB port alone is great on a power supply
2022-01-05T14:00:13 < ventYl_> karlp: I guess that just put something, they regularly supply to chinafabs online to aliexpress

2022-01-05T16:31:31 < Xogium> BrainDamage: why not ? Grounding ?
2022-01-05T16:31:51 < BrainDamage> if you're soldering, it wicks away heat, and if you're testing, chance of shorts
2022-01-05T16:32:14 < Xogium> BrainDamage: not for soldering in my case, obviously. Just want to hold my boards and have hand free when I wire up things
2022-01-05T16:32:48 < BrainDamage> add some tape to insulate the bottom plate
2022-01-05T16:33:15 < Xogium> why would they make an all-metal holder if its that bad ?
2022-01-05T16:34:40 < BrainDamage> because people buy it?
2022-01-05T16:35:16 < Xogium> yeah but… if they know it can cause problem, why would they get that ?
2022-01-05T16:35:25 < Xogium> granted, I figured for soldering it was a bad idea
2022-01-05T16:35:44 < Xogium> but I hoped that it would at least be sanely grounded
2022-01-05T16:36:07 < BrainDamage> maker stuff seems to be more about form before function
2022-01-05T16:36:12 < Xogium> grounded maybe not the correct word
2022-01-05T16:36:12 < BrainDamage> https://www.adafruit.com/product/3791 for a tiny price change
2022-01-05T16:36:44 < BrainDamage> this one holds the pcb with two clamps on the side
2022-01-05T16:36:57 < BrainDamage> so minimal heat transfer
2022-01-05T16:37:11 < BrainDamage> and minimal short chance

2022-01-05T16:43:10 < BrainDamage> it's just a bit pricey
2022-01-05T16:45:11 < Xogium> yeah and it can hold multiple boards so I guess its a plus too
2022-01-05T16:45:51 < Xogium> so would be stable enough for me to have both of my hands free for wiring up stuff to gpio ?
2022-01-05T16:46:43 < BrainDamage> i'd say so
2022-01-05T16:47:33 < BrainDamage> it has a long rod acting as a rail
2022-01-05T16:47:36 < Xogium> I mean I can do it with the pcb flat on the desk, but its not very stable, and it can slide around if I don't hold it with at least one hand
2022-01-05T16:47:53 < Xogium> which makes it very annoying to count pins and place wires all with a single hand
2022-01-05T16:47:57 < BrainDamage> if you clamp that, the position will be super still

2022-01-05T19:30:42 < BrainDamage> so a result some things are not standardized
2022-01-05T19:31:02 < BrainDamage> even mundane stuff like screen recording

2022-01-05T19:32:12 < jadew> heh
2022-01-05T19:36:18 < BrainDamage> it has a security model, its development is not stuck since > 10 years, and it doesn't have pointless ( 5-6 ) callbacks for a simple canvas paint
2022-01-05T19:36:47 < BrainDamage> problems include, the security model is always on with no way to turn it off
2022-01-05T19:37:00 < fenugrec> yes, and I think it's supposed to be less retarded on HiDpi displays, but... it's still broken for a lot of use cases
2022-01-05T19:37:33 <@karlp> well, it's been transparent for me until I tried to do screen recording :)
2022-01-05T19:37:43 < BrainDamage> the complete mess of its development state where each wm is its own standard
2022-01-05T19:38:08 < fenugrec> 4k is completely unusable with X (don't get me started on "oh just enable software rescaling for UI elements/fonts")
2022-01-05T19:38:30  * karlp enables rpmfusion again and installs obs
2022-01-05T19:38:37 < Xogium> wayland is still a no go if you use a screen reader since it completely blocks functions like mouse emulation from working, or flat review where you read the content of a window without actually moving the cursor
2022-01-05T19:39:25 < BrainDamage> until 2 years ago or so you couldn't even have global decorationns due to gnome vetoing them

2022-01-05T19:45:37 < fenugrec> clipping low it seems
2022-01-05T19:46:10 <@karlp> yeah, deliberately demo'd clipping low, the python dac api is ampli+offset, and truncates the bottom.
2022-01-05T19:46:22 <@karlp> was jsut fiddling
2022-01-05T19:46:31 < fenugrec> is that via usb-tmc
2022-01-05T19:46:37 <@karlp> hah, no.
2022-01-05T19:47:05 <@karlp> I have done that int he past, but usb-tmc is just a shitty suuuuuper thin layer to send bytes to the device and a shitty emulation to do the irq request that gpib allows
2022-01-05T19:47:49 <@karlp> there's zero standardized behaviour anyway, and declaring custom scpi dialects vs just a python api via ctrl requests is ~same, but wayyyy less code on both sides..
2022-01-05T19:48:43 < fenugrec> yeah, you'd be piping SCPI stuff over usb-tmc

2022-01-05T20:04:50 < fenugrec> well you wouldn't, you use an scpi lib, but TBH I haven't used anything usb-tmc. Just thought it'd be ~more versatile, but hardly more than piping SCPI stuff over a usb-CDC link I guess

2022-01-05T20:06:15 <@karlp> I've done it both ways, and honestly, if I'm not trying to make something that _has_ to be a specifici scpi dialect, this is wayyyyy lighter and easier.
2022-01-05T20:06:17 < fenugrec> granted
2022-01-05T20:06:21 <@karlp> the entire host side library is just https://paste.jvnv.net/view/nEzwz
2022-01-05T20:06:25 < fenugrec> but... python
2022-01-05T20:06:58 <@karlp> having concerns abotu python, but preferring to open a serial connection to write text commands into?
2022-01-05T20:07:05 <@karlp> not sure I'm gonna take that seriously :)
2022-01-05T20:07:27 <@karlp> my video shows intereactive use quite happily (it even works across suspend!)
2022-01-05T20:07:43 <@karlp> and you even get tab completion, with help, from the python interpreter, unlike what you'd get in scpi text
2022-01-05T20:07:52 < fenugrec> partly serious, yes - I don't enjoy writing or using python, and if I can avoid it I do.
2022-01-05T20:08:10 <@karlp> I can show you libusb ctrl calls in lua if you'd prefer? :)
2022-01-05T20:08:24 <@karlp> I'm pretty sure you can use libusb frrom "take your pick" language...
2022-01-05T20:09:16 < fenugrec> you're writing libusb calls... how is that better than using a serial connection ?
2022-01-05T20:09:39 < fenugrec> just to simplify fw side ?
2022-01-05T20:09:51 < jpa-> to simplify both sides
2022-01-05T20:10:01 <@karlp> yes, and the host side sw is still super slim., like i pasted.
2022-01-05T20:10:19 <@karlp> if you want to make that sending properly formatted scpi text relibaliy, you end up with a library on top as well.
2022-01-05T20:10:37 <@karlp> so scpi is "yay" for people poking it by hand, and .... pretty crap for just about anything else.

2022-01-05T20:14:20 < fenugrec> hm, I thought tk kinda depended on tcl ties/api or whatever
2022-01-05T20:14:42 <@karlp> nah, tcl/tk is famous, but I used perl/tk and python/tk as well,
2022-01-05T20:14:55 <@karlp> it's just a shitty primitive windowing toolkit

2022-01-05T20:15:48 < mawk> also it's not a mandatory package to have when you build python so you might have python without it that way
2022-01-05T20:16:03 < fenugrec> huh I wrote a tcl+tk UI in 2015 and I had totally forgotten. But I've been debugging a commercial TCL program and I have nothing nice to say about it
2022-01-05T20:16:10 <@karlp> oh yeah, fuck tcl.

2022-01-05T20:16:31 < mawk> it could be worse, like bash
2022-01-05T20:16:38 < ventYl_> perl!
2022-01-05T20:16:48 <@karlp> perl is at least documented and has types.
2022-01-05T20:16:58 <@karlp> tcl is everythings a string, maybe, mostly...
2022-01-05T20:17:10 < fenugrec> tcl "everything is a string" is fun until you try and do actual work
2022-01-05T20:17:17 < mawk> yes maximum convenience that way
2022-01-05T20:17:19 <@karlp> you _can_ write nice perl, even if people don't normally do it.
2022-01-05T20:18:09 < fenugrec> so what's cool to script a GUI these days ? 
2022-01-05T20:18:27 < jpa-> html + javascript
2022-01-05T20:18:32 < BrainDamage> people who use perl have the horrible tendency to pretend everything is a nail for regexes to hammer
2022-01-05T20:18:33 < fenugrec> yeah, gross, but ok
2022-01-05T20:19:52 < jpa-> now that webusb is in chrome everywhere, html+javascript is actually a very viable platform for simple interfaces for embedded stuff
2022-01-05T20:20:45 < fenugrec> I definietly don't want my browser to have anything to do with USB, what a horrible... why
2022-01-05T20:20:47 < BrainDamage> great, more attack surfaces to latch on
2022-01-05T20:20:53 < fenugrec> ^
2022-01-05T20:21:25 < jpa-> have you checked how webusb does security?
2022-01-05T20:22:12 < jpa-> and is it really safer to download an .exe from some random company to configure some weird device?
2022-01-05T20:23:09 < BrainDamage> yes, because once you download it is immutable
2022-01-05T20:23:10 < fenugrec> I know I like to be able to configure shit without going online, so what do you do, download the web page ? 
2022-01-05T20:23:31 < jpa-> BrainDamage: huh? why do you think so?
2022-01-05T20:24:00 < BrainDamage> because it's normally stored in non user-writeable locations
2022-01-05T20:24:02 < jpa-> fenugrec: ideally yeah, it would be a single .html - but in practice probably not, which is kind of sad

2022-01-05T20:29:43 < jpa-> everything is, but i don't understand why people get so cooked up about webusb as attack surface
2022-01-05T20:29:56 < jpa-> it is much better defined than e.g. webgl
2022-01-05T20:30:21 < jpa-> and besides requires user interaction + specific usb descriptors
2022-01-05T20:30:25 < kakium69> using webusb to repragram usb device?
2022-01-05T20:30:45 < BrainDamage> i don't give it more weight than eg smart card
2022-01-05T20:31:19 < BrainDamage> but as tangential thought, browser specs are steadily growing larger
2022-01-05T20:32:03 < BrainDamage> it makes almost impossible for a competitor to write an engine from scratch
2022-01-05T20:32:45 < jpa-> still a much better situation than everything being locked to windows API
2022-01-05T20:32:58 < jpa-> at least we still have two relevant browser engines
2022-01-05T20:33:15 < jpa-> and both of them open source and portable
2022-01-05T20:38:41 < mawk> what kakium69 
2022-01-05T20:38:45 < mawk> to be out of money already?

2022-01-05T20:39:19 < mawk> yes exactly kakium69 smokes reindeer joints
2022-01-05T20:39:24 < kakium69> but when I was working I didn't

2022-01-05T20:44:02 < mawk> maybe adding the flu on top to complete the experience could be a good idea
2022-01-05T20:44:18 < mawk> don't worry I can't die
2022-01-05T20:44:26 < mawk> I failed several times
2022-01-05T20:44:52 < kakium69> you don't go twice as hard when you have had a pause?
2022-01-05T20:45:23 < mawk> you mean thrice as hard? sure, and I never died
2022-01-05T20:45:34 < mawk> it's hard to die on that stuff
2022-01-05T20:45:52 < mawk> basically you'd need to drink booze concomitantly to die, or be naive with no tolerance
2022-01-05T20:46:36 < mawk> since I have opiate resistance 100 in my stats sheet I can't die

2022-01-05T22:41:31 < fenugrec> does my bode diagram look sane https://ibb.co/RNqz3Qh
2022-01-05T22:41:35 < fenugrec> *plot
2022-01-05T22:42:26 < mawk> it looks plausible
2022-01-05T22:42:40 < mawk> you tried computing it by hand?
2022-01-05T22:43:04 < mawk> it's a band-cut filter?
2022-01-05T22:43:22 < mawk> ah I didn't see the scale, 180dB
2022-01-05T22:43:48 < fenugrec> no, it's a voltage reference buffer
2022-01-05T22:44:46 < fenugrec> by hand : I'm not comfortable enough with s-domain stuff for that, especially for this weird configuration with the NPN pass and floating supply. I understand it well enough to design the circuit but certainly not model it
2022-01-05T22:45:48 < fenugrec> I'm surprised how much phase the "ccomp" capacitor adds around 100kHz when ccomp=15nF
2022-01-05T22:46:23 < fenugrec> I think it's a believable result; no ccomp capacitor is completely unstable on a breadboard, ccomp=1nF marginal

2022-01-05T23:59:03 <@karlp> I just got sent a quote breakdown frrom the local 3d printer guys,
2022-01-05T23:59:31 <@karlp> it's insane, it's a full cost breakdown including depreciation, how much they paid for each reel of filament, what their markup is, percentage failure rates.
2022-01-05T23:59:39 <@karlp> like, yay, transparency, but wow guys
--- Day changed Thu Jan 06 2022
2022-01-06T00:00:26 <@karlp> it includes different kwh/hr runtime costs for the different printers in their fleet
2022-01-06T00:02:06 <@karlp> they have by all accounts quite realistic prices on ~everything.
2022-01-06T00:02:17 <@karlp> they have minutes of labour estimates, all so far so good
2022-01-06T00:02:28 <@karlp> then they allow themselves a grand total of 50 ISK/hr for labour costs :)
2022-01-06T00:02:39 < qyx> is that much
2022-01-06T00:03:00 < qyx> 0.34 €?
2022-01-06T00:03:28 <@karlp> yes, exactlt that silly :)
2022-01-06T00:03:46 <@karlp> prompt, local, but we'll see how pro they really are :)
2022-01-06T00:04:25 < ventYl_> well at least they are honest
2022-01-06T00:05:08 <@karlp> yeah, he called me later, was prepared to drive it round _now_ if it was urgent.
2022-01-06T00:05:52 <@karlp> recommends I measure it to check though, "you need to calibrate printers fairly often, so that mm == mm, you have something that actually needs to be the right size, make sure to check it when you get it, incase we need to make some tweaks"
2022-01-06T00:05:56 <@karlp> which was... not encouraging,
2022-01-06T00:06:06 <@karlp> like, this is _why_ I'm paying someone else to make it :)
2022-01-06T00:11:49 < Mangy_Dog> https://imgur.com/gallery/Ul3FW0y Tricorder reposting :D 
2022-01-06T00:12:42 < qyx> what do they want to calibrate, steppers not stepping in even steps?
2022-01-06T00:22:14 < zyp> flow rate is probably the biggest one
2022-01-06T00:22:59 < zyp> if the filament diameter is not precise, that'll fuck up flow rate
2022-01-06T00:23:17 < zyp> and I guess also how well the filament engages with the drive wheels
2022-01-06T00:29:27 < fenugrec> thermal shrink too
2022-01-06T00:29:46 < ventYl_> typically you calibrate flow rate and align your support to be level
2022-01-06T00:30:12 < ventYl_> first due to nozzle wear, latter due to spring-loaded fashion of support mounting
2022-01-06T00:33:24 < BrainDamage> can't flow rate just be measured?
2022-01-06T00:33:43 < BrainDamage> you can eg put the reel on a scale
2022-01-06T00:34:05 < BrainDamage> or monitor the diameter

2022-01-06T11:55:03 < steve__> why do thru hole pots have those legs that the body stands on, instead of the body touching the board flush?  https://www.taydaelectronics.com/media/catalog/product/cache/3727e7324aff0beca75a17e6d9fba59e/A/-/A-5622-1_1.jpg at first I thought the "legs" were meant to go thru the board for stability, but the recommended footprint only shows 5 holes, 3 for the leads and 2 for the 2 "long legs".  and I see other pots in products like this one, 
2022-01-06T11:55:03 < steve__> the body is "standing on those legs"
2022-01-06T11:59:09 <@karlp> steve__: you might find they have product version with different heights?
2022-01-06T12:02:28 < steve__> the commonly available ones of that style seem to all have those "leg tab things" so i figure there's a reason.  like those anti-rotation tabs which are always there but many times are clipped off in production.  My best guess is it allows SMT components to be populated under.  or perhaps heat dissipation?

2022-01-06T12:05:34 <@karlp> if you are dissipating enough heat in a big metal cased pot like that, you're already in serious danger of buring out the carbon contacts, I would find that anunlikely explanation.

2022-01-06T14:36:21 < drzacek> hello there
2022-01-06T14:36:57 < drzacek> am making a simple own pcb project
2022-01-06T14:37:04 < Xogium> if y'all want a real recording, I have one of 4 mortar shots. Blank shots that is, but still
2022-01-06T14:37:24 < drzacek> according to datashieet and hardware design guides, I need extra capacitors for VDDA pin on my stm32
2022-01-06T14:37:54 < drzacek> I've seen a project from my friend and he used separate LDO for the VDDA (and obviously all the required and not required capacitors)
2022-01-06T14:38:05 < drzacek> are there like any advantage of that?

2022-01-06T14:38:58 < jpa-> drzacek: a good high-PSRR LDO does have advantages, especially if you have high pulsing loads on VDD and want 12+ bit accuracy from ADC
2022-01-06T14:39:23 <@karlp> (doing RMS on a periodic signal, but not having the correct frequency to be taking integral multiples of waveforms)
2022-01-06T14:39:28 < jadew> drzacek, sorry
2022-01-06T14:39:36 < drzacek> haha its ok
2022-01-06T14:39:43 < drzacek> but what the hell
2022-01-06T14:40:12 < drzacek> I assume there were some "audio" features aswell, but my headset is charging so dunno
2022-01-06T14:40:19 < jpa-> IIRC there was someone here who had a blinking debug led and it was visible on ADC readings, because the VDD load caused VDDA to change a tiny bit
2022-01-06T14:40:41 < drzacek> jpa-, but it all comes from same source anyways
2022-01-06T14:40:50 <@karlp> jpa-: that's been me, at least once :)
2022-01-06T14:41:06 < drzacek> it's 5V USB powered project with 3x 3.3V LDOs, the second only for VDDA.
2022-01-06T14:41:34 < drzacek> okay, so it's worth considering, especially when those LDOs are not super expensive
2022-01-06T14:41:38 < jpa-> drzacek: yes, but regulator output voltage depends more on the load on its output than it depends on the voltage on its input
2022-01-06T14:42:05 < jpa-> so if you have constant load on VDDA but pulsing load on VDD, then separate regulator will give more stable VDDA voltage
2022-01-06T14:42:13 < drzacek> jpa-, yeah but what if the load on the first ldo is high enough to destabilize USB power, thus 5v input for the second ldo?
2022-01-06T14:42:33 < drzacek> pulsing load like PWM controlled backlight for tiny LCD?

2022-01-06T14:42:47 < jpa-> if you "destabilize" USB power enough to drop it from 5V to below the about 3.7V required for LDO, then you have bigger problems
2022-01-06T14:43:06 < jpa-> yeah, PWM backlight would definitely be a pulsing load
2022-01-06T14:43:30 < drzacek> okay, noted
2022-01-06T14:43:59 < jpa-> but then again, if you are not aiming for very high precision measurements, the little bit of pulsing on VDDA may not matter

2022-01-06T14:47:43 < drzacek> well I wanted to measure temperature and LiPo voltage, so I would want SOME analog. If I can get it better than worse then why not. I think it wont hurt the budget? 
2022-01-06T14:48:01 < drzacek> but it gonna steal some space on the pcb
2022-01-06T14:49:00 < jpa-> for both of those 1% seems like it would be enough and that's easy enough even without separate regulator
2022-01-06T14:49:29 < jpa-> and both of those are so slowly changing that you can average over e.g. 100 ms to cancel out most noise

2022-01-06T15:01:30 <@karlp> ^^ 
2022-01-06T15:08:16 < drzacek> ok. I'll make me a notice to use that in case Im gonna do something more analogy, and stick with single ldo this time
2022-01-06T15:14:21 < jpa-> and when you want really analogy stuff, you'll want the separate VDDA LDO to be a special low-noise high-psrr model, and you'll also want a separate VREF+ source if the microcontroller supports it
2022-01-06T15:14:51 < jpa-> but that would be for 16+ bit resolution / 0.01% accuracy stuff
2022-01-06T15:21:40 <@karlp> if you've got a reallly good vdda, the only benefit of vref+ is if you want more dynamic range by using lie a 2.048V ref on a 3.3v supply though right?
2022-01-06T15:21:54  * karlp at least doesn't consider it useful, but he doesn't look for 0.01% either....
2022-01-06T15:22:12 <@karlp> I'd at least put more weight on vdda than vref.
2022-01-06T15:22:53 <@karlp> but I'll certainly defer to your analog wisdom, not my peanuts :)
2022-01-06T15:24:44 < jpa-> i would say the benefit is that high accuracy reference shunts cannot always source enough current for powering the ADC also
2022-01-06T15:28:29 <@karlp> because it supports my argument, ST describes the use of the vref+ pin as, "To ensure a better accuracy on low-voltage inputs and outputs, the user can connect to
2022-01-06T15:28:31 <@karlp> V REF+ a separate reference voltage lower than V DDA"
2022-01-06T15:29:55 < jpa-> IIRC the STM32 16-bit ADC on e.g. STM32H7 can divide the internal reference also
2022-01-06T15:32:46 < jpa-> but yeah, for 12 bit ADC i don't expect there would be any noise or accuracy benefit in separating them

2022-01-06T16:02:20 < fenugrec> about 300 ? I haven't used many other uscopes but I think the optics are not great, field of view is not the largest, DOF pretty shallow at higher zooms (this is to be expected; not sure if better scopes do better in this regard)
2022-01-06T16:03:32 < jpa-> oh, and smartphone also has autofocus!
2022-01-06T16:04:58 < drzacek> jpa-, karlp from what I see on the lqfp64 stm32l431, there is no ref+ pin, or rather - it is shown on VDDA. Not sure how to understand this, how can this be alternative function? Either I power it internally and provide my own reference, or I power it externally and provide internal ref?
2022-01-06T16:05:27 < fenugrec> pretty happy with it though. Would buy again. It's nice to work on small shit without having to lean down to the table and stick my head 10cm from the pcb. 
2022-01-06T16:05:46 < jpa-> drzacek: STM32L431 only has 12-bit ADC, it is probably hardwired to use VDDA as reference
2022-01-06T16:06:01 < drzacek> 12bit is enough for me
2022-01-06T16:06:39 < jpa-> yeah, and for 12bit external references and whatever are rarely used - if you need to measure smaller range, easier to just multiply the input with opamp
2022-01-06T16:06:56 < jpa-> (STM32L431 does have opamp built-in for that)
2022-01-06T16:07:11 < drzacek> I saw it in cubemx, but not sure how to use that
2022-01-06T16:07:25 < fenugrec> unless you want a 2.048V to simplify some math, I guess
2022-01-06T16:07:32 < drzacek> I still have other project waiting with 4 op amps, for measuring -10..+10V analogue value
2022-01-06T16:07:46 < drzacek> not sure how well it can be measured with 3.3V mcu and 12bit precision
2022-01-06T16:08:27 < fenugrec> lowpass, scale, clamp, buffer, measure
2022-01-06T16:08:31 < jpa-> it can be measured with about 5mV resolution, though expect about 20mV of noise before averaging
2022-01-06T16:10:19 < jpa-> three resistor divider with e.g. input -> 33kohm -> ADC,  VDD -> 10kohm -> ADC,  GND -> 10kohm -> ADC   and then if you want extra protection, some external clamping diodes

2022-01-06T16:10:39 < drzacek> 5mV kinda sucks
2022-01-06T16:10:51 < drzacek> need 1mV exact value
2022-01-06T16:11:06 < jpa-> you can also just put external mcp3464 or similar
2022-01-06T16:11:48 < fenugrec> simple math... (10 - -10) / .001 = 20e3; log2 (20e3) = 14.3 bits ADC is what you "need"
2022-01-06T16:12:28 < jpa-> yeah, and without averaging typical 12 bit ADC has 10 bit effective resolution.. with long averaging it may get 13 or 14 bit resolution, but often the linearity is still on 12 bit level
2022-01-06T16:12:41 < drzacek> if my range is 20V (-10 to 10V), and I shrink it down to 3.3 (it will be less than 3.3, I know), then I have shrunk my original range 6.06060606 times. A 12bit on 3.3V would result in 0,000805, multiplied by my 6.06, its on 0,0048V
2022-01-06T16:12:43 < drzacek> damn, 5mV
2022-01-06T16:14:41 < fenugrec> science !
2022-01-06T16:15:09 < qyx> +- 10 V?
2022-01-06T16:15:13 < qyx> what for is that?
2022-01-06T16:15:23 < drzacek> setpoint output on old analogue cnc controllers
2022-01-06T16:15:28 < drzacek> wanted to diy some simple tester 
2022-01-06T16:16:02 < fenugrec> maybe a "simple tester" can live with 5mV resolution... not sure an old PLC / cnc controller will be doing much better

2022-01-06T16:17:36 < drzacek> when they output "0V", they usually do 0.003V, or -0.007V
2022-01-06T16:17:38 < qyx> *PXI
2022-01-06T16:17:49 < drzacek> and they need to know that offset in software to compensate
2022-01-06T16:18:12 <@karlp> fenugrec: I don't really understand the appeal fo 2.048v references now that it's all digital anyway :)
2022-01-06T16:18:25 <@karlp> it was fine when you were wiring the voltage direct to a dial, but... just why these days :)
2022-01-06T16:18:47 < jpa-> drzacek: you can also measure with two ranges, one range for +-10V and other range for +-1V
2022-01-06T16:19:03 < drzacek> yeah that is my current idea 
2022-01-06T16:19:17 < drzacek> but, would require some kind of protection in case I forget to change output to +-1V
2022-01-06T16:19:29 < drzacek> otherwise the 10V will cause some magic smoke?
2022-01-06T16:19:33 < jpa-> clamping
2022-01-06T16:20:07 < fenugrec> karlp, I'm thinking of a (contrived)  edge case where one couldn't afford the extra mul + div rescale in software  to get "nice" mV-to-adc conversion
2022-01-06T16:21:16 < jpa-> you only need a multiply
2022-01-06T16:21:45 < benishor> drzacek: how often do you need to read?
2022-01-06T16:21:53 < drzacek> it doesnt have to be fast
2022-01-06T16:22:25 < benishor> then switching reference should be fine, I reckon?
2022-01-06T16:22:26 < drzacek> I hook it up, then I set in test software the values and it can take all the time in the world 
2022-01-06T16:22:47 < drzacek> switching reference?
2022-01-06T16:24:07 < fenugrec> just use 2 adc pins, one for full scale +-10, other one amplified +- 0.1 or whatever

2022-01-06T16:25:26 < benishor> ^
2022-01-06T16:25:48 < benishor> nevermind the "switching reference" part, I was talking bs
2022-01-06T16:25:56 < benishor> didn't really get what you were on to
2022-01-06T16:26:23 < benishor> can't you simply deal with it with averaging more measurements?
2022-01-06T16:26:44 < benishor> since time is not a hard constraint
2022-01-06T16:27:11 < jpa-> averaging will reduce noise and may increase resolution a bit, but it won't increase linearity
2022-01-06T16:28:07 < benishor> well, it depends on the other side of the problem too, no?
2022-01-06T16:28:19 < benishor> that particular offset will be added to something
2022-01-06T16:28:39 < benishor> if the resolution there is too low then ...
2022-01-06T16:28:53 <@karlp> if you're only looking for offset, you don't actually need to measure over 10v+- :)
2022-01-06T16:29:28 <@karlp> tvs in case it's running at full tilt, then just measure it at 3.3v, should give you more resolution...
2022-01-06T16:30:11 < drzacek> its just one of the tests
2022-01-06T16:30:38 < benishor> drzacek: what's the actual use case?
2022-01-06T16:30:42 < drzacek> other test is to check if they can output full range. this doesn't have to be that exact, if it does 9.8, it is okay, no need to know if it does 9.80001
2022-01-06T16:31:05 < drzacek> benishor, testing and repairing old cnc stuff
2022-01-06T16:31:20 < benishor> drzacek: how much accuracy do you need?
2022-01-06T16:32:05 < drzacek> when looking for the offset from 0V (low value, around 10mV around 0V), I need 1mV exact value, for other tests I need maybe 0.1V
2022-01-06T16:33:33 < drzacek> right now I am testing it by hooking multimeter to the output and looking for the value. Then unlpug and check other 3 outputs. It needs to be done often enough to justify a little helper
2022-01-06T16:34:33 < drzacek> sometimes those suckers work fine, but when get hot (after few hours of working) and then start to having problems with output. If I had an stm32 thingy that measures all 4 values and logs it, maybe to SD card, then I could leave it running at night and just check in the morning how it went
2022-01-06T16:34:50 < jpa-> simple solution could be just to use a multimeter with USB connection and a cheap USB relay board from eBay
2022-01-06T16:35:52 < drzacek> the dual range solution seems nice. not sure how to implement it yet, but I only need to find the offset value once and done, then in long run tests it can run in the other mode
2022-01-06T16:36:05 < drzacek> would be nice to have some autorange, like some multimeters do
2022-01-06T16:37:09 < drzacek> but maybe some other day
2022-01-06T16:37:31 < fenugrec> drzacek, like I said, 2 ADC pins, measure on the fullscale pin first, if it's within range for the other pin, use its reading... boom, software autorange
2022-01-06T16:38:21 < drzacek> fenugrec, well, I measure 4 values, so would need 2x4 = 8pins, I think most mcus have that, but still
2022-01-06T16:38:31 < fenugrec> I think most mcus have that.
2022-01-06T16:38:35 < drzacek> I would need to change the resistor values for the OP amps to change the range
2022-01-06T16:38:40 < fenugrec> ?
2022-01-06T16:39:12 < drzacek> the voltage divider on the feedback of the op amp decides the range
2022-01-06T16:39:46 < jpa-> that STM32L4 also has the PGA on the opamp that you can use for amplification afterwards.. though it is going to have its own offset also, which may be a problem
2022-01-06T16:40:50 < fenugrec> you can probably get away with 1 opamp per "channel" and just a few resistors + diodes to divide the fullscale input to 0-3.3
2022-01-06T16:42:22 < fenugrec> or 2 opamps... what's the cost difference for just one of these testers
2022-01-06T16:42:28 < drzacek> I got 4 op amps in single pack for that, I actually had whole schematic done, but guess it needs major rework
2022-01-06T16:42:54 < drzacek> well I guess using 2 of those chips is some solution
2022-01-06T16:43:21 < drzacek> but the tricky part is finding the R values - I had planned to use 2 potentiometers and fine tune it to the perfect values once assembled
2022-01-06T16:43:58 < fenugrec> or calibrate it after. Just save raw values (you're logging anyway) and postprocess
2022-01-06T16:44:07 < jpa-> huh, isn't that a very simple calculation or just use a simulator like falstad if you are lazy
2022-01-06T16:45:03 < fenugrec> or if you're worried of component tolerances, leave a few empty footprints to add parallel resistors to adjust values
2022-01-06T16:45:36 <@karlp> kicad simulation lets you have sliders for resistors... :)
2022-01-06T16:46:12 < jpa-> karlp: last time i tried it the sliders were very unreliable for some reason.. almost as bad as ebay potentiometers :D
2022-01-06T16:47:07 <@karlp> hrm, worked ok for me last time, but you have to have your step size big enough that it doesn't churn too badly on mouse move
2022-01-06T16:47:19 <@karlp> (I think it's synchronous bad ui....)
2022-01-06T16:47:36 < jpa-> maybe it was something like that, for me it updated sometimes and sometimes did not
2022-01-06T16:48:05 <@karlp> I think I ended up using it as just four text fields I could type into, instead of having to edit the schematic repeatedly...
2022-01-06T16:57:55 <@karlp> zyp: did you ever get a look at the rest of what I had in https://github.com/karlp/laks/tree/karl-top1 for your dev_v2 branch?

2022-01-06T17:23:05 <@karlp> aight.
2022-01-06T17:23:34 < jpa-> drzacek: 0.1% resistors are pretty cheap and if you combine two, you can always get within 0.1% of the value you want

2022-01-06T17:41:12 < jpa-> drzacek: sure you can, just resistor divide to VDDA
2022-01-06T17:41:32 < drzacek> uhm what?
2022-01-06T17:41:33 < jpa-> basic three resistor divider, one to input, one to gnd and one to vdda
2022-01-06T17:41:46 < zyp> yep
2022-01-06T17:41:55 < drzacek> I think I don't follow
2022-01-06T17:42:27 < drzacek> a divider would scale a voltage down, aka make 3.3 from 10, but it wont shift the -5 to over 0V ?
2022-01-06T17:42:41 < zyp> sure it can
2022-01-06T17:42:48 < drzacek> how?
2022-01-06T17:43:03 < zyp> you take a plain resistor divider and add a third resistor between centerpoint and Vdd
2022-01-06T17:43:40 < zyp> sized correctly it'll keep any input from negative A to positive B within 0-3.3V

2022-01-06T17:46:14 < drzacek> what
2022-01-06T17:46:14 <@karlp> I :heart emoji: falstad
2022-01-06T17:46:28 < zyp> measuring the voltage of the centerpoint, you know the voltage across both the gnd resistor and the vdd resistor, and hence the current through either
2022-01-06T17:46:44 < jpa-> karlp: yeah, it is 99% of everything one needs of a simulator, plus very easy to share :)
2022-01-06T17:47:06 < zyp> and the current sum of the centerpoint is zero, so you also know the current through the third resistor, and hence the voltage difference from the centerpoint
2022-01-06T17:47:53 < jpa-> drzacek: a resistor divider is really a weighted sum circuit - the GND "0 volts" is nothing special, it is just a value among others: VOUT = (V1 / R1 + V2 / R2) / (1/R1 + 1/R2)   or something
2022-01-06T17:48:18 < jpa-> then add a third one and you can sum 0V, 3.3V and input voltage in what ever ratios you want

2022-01-06T17:52:19 < drzacek> if I add third on, coming from the vcc
2022-01-06T17:53:25 < drzacek> I see it, but don't understand whats going on
2022-01-06T17:54:15 < jpa-> drzacek: for any number of resistors in a divider, the voltage is weighted average between the input voltages
2022-01-06T17:54:45 < jpa-> for the simplest divider, someone has just decided that one of the voltages has to be 0V, and has provided the simplified formula   VOUT = R1 * VIN / (R1 + R2)
2022-01-06T17:55:10 < jpa-> but if you want, you can average together 3.1415, 2.7182 and 9999 volts
2022-01-06T17:56:41 < drzacek> I dont even know how to start calculating this
2022-01-06T17:58:28 < zyp> start with ohm's law and continue with kirchhoff's
2022-01-06T17:59:14 < drzacek> ok
2022-01-06T18:00:01 < jpa-> using some superposition handwaving, calculate currents coming through each resistor:   V1/R1 + V2/R2 ...,  then multiply that by the output impedance which you get from parallel resistors (thevenin equivalent) as  1 / (1/R1 + 1/R2 + ...)    and you get the formula i gave above:  VOUT = (V1/R1 + V2/R2 + ...) / (1/R1 + 1/R2 + ...)
2022-01-06T18:00:14 < jpa-> works for any number of resistors, but of course you'll learn more if you derive it yourself :)

2022-01-06T18:02:44 < zyp> but let's say you have 2k/2k/10k connected between 0V/5V/input and you measure 2V at the centerpoint with the ADC
2022-01-06T18:03:37 < zyp> that's 2V/2k = 1mA to 0V and (5V-2V)/2k = 1.5mA from 5V
2022-01-06T18:05:01 < zyp> so you've got 0.5mA through the 10k, i.e. 5V across it, and 2V-5V = -3V on the input

2022-01-06T18:45:55 < Laurenceb> saw a really weird surge failure: power input socket arced internally, generating a high voltage differential input, which caused a hybrid electrolytic cap to internally arc
2022-01-06T18:45:56 < kakium69> approved for what?
2022-01-06T18:46:06 < Laurenceb> CE/applicable standards
2022-01-06T18:46:18 < kakium69> :o
2022-01-06T18:46:33 < kakium69> did you use wrong connector?
2022-01-06T18:46:55 < Laurenceb> yeah, but _I_ didn't ""connector expert" guy specced it
2022-01-06T18:47:01 < kakium69> apple pro book level connector oof?
2022-01-06T18:47:03 < fenugrec> people will gladly/blindly pay with their privacy to get voice recognition, mapping, "search in your area", traffic conditions  etc.
2022-01-06T18:47:36 < Laurenceb> fenugrec: hyperloop team got stuck in traffic and I told them to check government sites
2022-01-06T18:48:11 < Laurenceb> they thought google traffic used phone tracking, so I had to point out that actually it scraped gov sites that use inductive sensors in the road
2022-01-06T18:48:25 < Laurenceb> then they found google has ~15 minute lag...
2022-01-06T18:48:54 < kakium69> doesn't google use phone tracking too?
2022-01-06T18:49:02 < fenugrec> of course
2022-01-06T18:49:12 < Laurenceb> maybe, but it wasnt working at all
2022-01-06T18:49:24 < kakium69> someone took like 50phones and carried them around in london creating virtual traffic
2022-01-06T18:49:24 < Laurenceb> gov site showed a jam but google had it as clear
2022-01-06T18:49:42 < kakium69> virtual traffic jams
2022-01-06T18:50:50 < Laurenceb> the surge fail was weird as the caps are protected by high power TVS diodes
2022-01-06T18:51:29 < Laurenceb> but it looks like peak current was >500A, so the caps ended up overvolted by ~100V during the arc
2022-01-06T18:52:02 < Laurenceb> basically this is a sim of traction power arcing onto data cabling
2022-01-06T18:52:07 < kakium69> you have CMC?
2022-01-06T18:52:32 < Laurenceb> yeah
2022-01-06T18:52:34 < kakium69> ah it doesn't need to survive?
2022-01-06T18:53:02 < Laurenceb> yeah it needs to meet criterion A, so not only survives but stays operating whilst getting blasted
2022-01-06T18:53:38 < kakium69> use optics
2022-01-06T18:53:55 < kakium69> fly-by-fibre
2022-01-06T18:54:01 < Laurenceb> the failure mode was weird, it blew its main power fuse, but when it replaced the fuse it booted up again without issue
2022-01-06T18:54:34 < kakium69> interestings
2022-01-06T18:54:37 < Laurenceb> and the TVS diodes still work ok
2022-01-06T18:54:45 < kakium69> how is your ground?
2022-01-06T18:54:53 < kakium69> really beefy?
2022-01-06T18:55:00 < Laurenceb> looks like electrolytic caps can arc internally then self heal later
2022-01-06T18:55:10 < Laurenceb> yeah M18 welded 304 stainless studs
2022-01-06T18:55:29 < kakium69> but your pcb gnd
2022-01-06T18:56:29 < Laurenceb> pcb is gold edge plated then crewed into milled enclosure after coating with conductive grease
2022-01-06T18:56:39 < Laurenceb> we werent sure about the grease but it seems to work
2022-01-06T18:58:30 < kakium69> how is impendance from TVS to ground studs?

2022-01-06T22:15:18 < kakium69> it just digged into ice

2022-01-06T22:44:07 < fenugrec> kakium69, as long as there's wind and enough leg to not get dragged head first through the snow : no problem
2022-01-06T22:44:40 < kakium69> are you strapped in or just hanging?
2022-01-06T22:45:11 < fenugrec> it's a harness, no way you can armwrestle one of those for more than a few minutes
2022-01-06T22:45:38 < kakium69> idk if you have tried that thing on t-bar ski lift when you fall and then continue up by hanging from the bar
2022-01-06T22:46:01 < fenugrec> yes. You can do something similar with kites but even less controlled

2022-01-07T10:12:46 < hiovoltage> for circular 6 channels ads reading, can one channel effect other channel?
2022-01-07T10:12:53 < hiovoltage> reading values
2022-01-07T10:13:03 < hiovoltage> adc*
2022-01-07T10:14:41 < jpa-> in principle it shouldn't, the ADC sample capacitor is reset to 0V between conversions
2022-01-07T10:15:16 < jpa-> but some STM32 models have documented errata where that can occur, especially if the voltages go outside ADC range
2022-01-07T10:15:56 < jpa-> and if your signals are high-impedance (>10kohm), you'll get capacitive coupling - though for such high impedance signals ADC conversion will require long sample time anyway
2022-01-07T10:22:45 < hiovoltage> i'm sure about voltage ranges are fine. But 2 of chnls have high-impedance(about 10k-15k), then i ll try to rising sampling time. Main freq is 180mhz and sampling time 32.5 cyc for each channel, right now

2022-01-07T11:02:05 < jpa-> for slow signals one can also add 1nF capacitor close to ADC pins; that way the energy comes from the capacitor instead of through resistor slowly, and faster sample times can be used

2022-01-07T11:05:03 < hiovoltage56> actually, i have 1nF caps for 4 channels, but i dnt know why i put 100nF caps for 2 high-impedance channels.
2022-01-07T11:05:21 < hiovoltage56> i will replace them with 1nF

2022-01-07T11:09:45 < jpa-> larger is better in a sense, but if the caps are not NP0 or C0G type you may be seeing acoustic coupling
2022-01-07T11:09:54 < jpa-> because capacitors work as speakers and microphones
2022-01-07T11:28:05 < hiovoltage> 100 nF caps are : https://www.lcsc.com/product-detail/Multilayer-Ceramic-Capacitors-MLCC-SMD-SMT_Samsung-Electro-Mechanics-CL05B104KO5NNNC_C1525.html
2022-01-07T11:28:47 < jpa-> yeah, X7R is microphonic
2022-01-07T11:30:48 < zyp> so which aren't? :)

2022-01-07T11:31:07 < hiovoltage> correct?
2022-01-07T11:31:22 < zyp> ah, right, missed the «not» in your first statement
2022-01-07T11:31:40 < jpa-> hiovoltage: yeah, that's better
2022-01-07T11:31:56 < hiovoltage> thanks
2022-01-07T11:32:20 < jpa-> the microphonic effects are larger at higher frequencies, which is why if you give it time to settle with longer sampling time, the problem disappears
2022-01-07T11:32:21 <@karlp> zyp: yar, I'm going to either need to be a) less insane or b) start working on a lot more then :)
2022-01-07T11:33:14 <@karlp> pwr/exti/ipcc/hsem so far, and it's been more than I thought so far, but we'll try shit out :)
2022-01-07T11:33:41 < zyp> shouldn't be hard to add exti, but I suspect that's one of the things that's not very uniform across the families
2022-01-07T11:36:12 < zyp> re: laks/ include prefix, if you want that you can add the parent dir of the submodule to CPPPATH :)
2022-01-07T11:38:35 <@karlp> yeah, I had a brief look at it, but just curious about overall direction.  it's lots of little files in lots of directories.
2022-01-07T11:38:45 < zyp> you could argue for putting everything inside a laks-dir in the laks repo, akin to how python repos are typically organized, which I'm not completely opposed to, but it's a change I'd like to put off
2022-01-07T11:38:56 <@karlp> yeah, it's not something blocking me :)
2022-01-07T11:39:14 <@karlp> currently I'm trying to dig up where I found the definitive specs on teh memory maps assumed for the wpan library.
2022-01-07T11:39:20 < zyp> the long term plan is to switch to C++20 modules once toolchain support is decent
2022-01-07T11:39:27 <@karlp> and deciding how much to yolo, and how much to do properly...
2022-01-07T11:39:30 < zyp> i.e. when gcc-arm-embedded ships gcc11 or so

2022-01-07T11:40:04 <@karlp> I'm still probably insane for trying, and not just using cube for my own portions, but... it will be educational at least.
2022-01-07T11:40:29 < zyp> it's gonna be interesting to see how it turns out
2022-01-07T11:40:47 < zyp> I'd love to have the entire CPU1 side of the stack in laks
2022-01-07T11:41:32 <@karlp> I'm not planning on that.
2022-01-07T11:42:04 < zyp> I know, but I might use your results later as a starting point to get there :)
2022-01-07T11:42:07 <@karlp> my idea is to take the cube wpan driver bit only... https://github.com/STMicroelectronics/STM32CubeWB/tree/0b858907b3cf836c051b674c38e69f01968d4e9e/Middlewares/ST/STM32_WPAN
2022-01-07T11:42:21 <@karlp> and use laks to to the wb targetted port to IPCC/HSEM
2022-01-07T11:42:29 <@karlp> but yeah, it would certainly be a starting point I gues.
2022-01-07T11:42:48 <@karlp> I'm writing horrific c in .cpp files of course, cos I'm an amateur hacking my way forward right now too.
2022-01-07T11:45:13 < qyx> haha
2022-01-07T11:46:40 < Steffanx> The entire radio part of the stm32wb isn't documented is it? So "impossible" to port other ble stacks to it etc.?
2022-01-07T11:46:59 < zyp> worse, it's inaccessible
2022-01-07T11:47:01 < srk> exti is compatible across families. only G0 is a bit different
2022-01-07T11:47:25 < zyp> the radio is only accessible from CPU2 and you're not allowed to run your own code on CPU2
2022-01-07T11:47:27 <@karlp> this is the idea: https://bin.jvnv.net/file/I5uZT/laks-stwpan-plan.png
2022-01-07T11:47:48 <@karlp> Steffanx: you can use it as a HCI though, 
2022-01-07T11:47:59 < zyp> so it's somewhat like interfacing with a SPI radio chip, except it's in a shared memory space instead of hooked to SPI
2022-01-07T11:48:10 <@karlp> you're "wasting" a lot of it's capacity that way, but you can then use whatever stack you like.
2022-01-07T11:48:34 <@karlp> ifyou  use st's "full"(er) stacks, you get more cpu offloading, but (obviously) much more tied to their api layers.
2022-01-07T11:48:52 <@karlp> I've got no existing shit using another stack, so I'm not looking at using it as  HCI device.
2022-01-07T11:49:13 <@karlp> srk: compatiblish, but not really....
2022-01-07T11:50:54 < zyp> for adding radio APIs to laks, I'd aim for API compatibility between stm32wb and nrf53 or something
2022-01-07T11:51:26 <@karlp> yeah, I won't be working on that much I don't think :)
2022-01-07T11:51:27 < zyp> since portability is one of the goals of laks :)
2022-01-07T11:51:36 <@karlp> I'll never get your c++ expressiveness anyway.

2022-01-07T16:25:41 < drzacek> I used the superstition method and was able to calculate same values as the falstad simulation. amazing that you can do that with 3resistor divider and additional source. I asked about it few months ago and only answer I got was to use op amps
2022-01-07T16:25:46 < ventYl_> kakium69: well, in theory, you can swap the bytecode and get different kind of programmable function

2022-01-07T18:34:49 < fenugrec> USB pros : when a device gets a Suspend event (3ms without SOF), and later a Resume, is it expected that it stays enumerated / addressed or would the host do a usb Reset anyway ?

2022-01-07T18:46:14 <@karlp> I would _expect_ that it should stay enumerated, but I've no idea what really happens.
2022-01-07T18:46:29 < Laurenceb> my understanding is that they stay enumerated
2022-01-07T18:46:43 <@karlp> I know heaps of people are like, "problems? turn off power saving" so there's absolutely shit heaps of shitty behavie when people even start using the usb low power stuff

2022-01-07T19:30:08 < kakium69> catphish: do you actually save any power by removing them?
2022-01-07T19:30:36 <@karlp> geh, I started stacking up st ble stuff into  file, but now I've got laks/st cmsis header conflicts, unsurprisingly..
2022-01-07T19:30:42 < catphish> kakium69: clearly yes, but that is not a consideration that matters
2022-01-07T19:30:59 < kakium69> what matters?
2022-01-07T19:31:23 < catphish> actually, i take that back, it won't save power, will it
2022-01-07T19:31:33 < kakium69> lets see
2022-01-07T19:31:38 < catphish> it'll have a much lower impedance above 3v3
2022-01-07T19:32:39 < kakium69> if you do resistor-zener thing you need higher resistance
2022-01-07T19:33:03 < catphish> oh, of course, it does save power because i could use a MUCH higher resistance
2022-01-07T19:33:53 < catphish> which also mitigates the need to worry about the power dissipation of the zener
2022-01-07T19:34:41 < kakium69> you have totem pole driver as a source?
2022-01-07T19:35:57 < kakium69> it only works if you have source that can sink and source
2022-01-07T19:36:54 < catphish> the source is liable to be push-only, ie a 12v source and a diode, but my thought process was that by removing the resistor, i could use a wider variery of sources, including an open drain with a pullup
2022-01-07T19:37:29 < catphish> but i wasn't sure if i was missing a disadvantage, i suppose the lack of pull-down is the main one, if the input is floating
2022-01-07T19:37:43 < catphish> and this is going to be in a noisy environment
2022-01-07T19:38:15 < kakium69> then you need to keep resistance rather low I think
2022-01-07T19:38:40 < catphish> perhaps i'll keep it simple and leave it as is
2022-01-07T19:38:53 < kakium69> did you copy it from somewhere?
2022-01-07T19:38:59 < catphish> no
2022-01-07T19:39:29 < catphish> it just seemed the obvious way to convert a noisy 12v input to 3v3
2022-01-07T19:45:15 < kakium69> you can add SMD choke
2022-01-07T19:45:21 < kakium69> if it's really noisy
2022-01-07T19:46:50 < kakium69> what kind of noisy?
2022-01-07T19:47:00 < kakium69> right next to spark plug wiring?
2022-01-07T19:51:34 < catphish> not that noisy, it's for an EV, so there'll be inverter noise, but nothing crazy

2022-01-07T22:48:55 < zyp> catphish, 1.5 seems too low when below 5.6
2022-01-07T22:49:23 < zyp> at 12V in you only get 2.5V out
2022-01-07T22:54:14 < zyp> pick the top side resistor to get a reasonable current at the zener breakdown voltage and then scale the bottom side resistor so that it's just large enough to not take the full current at zener voltage
2022-01-07T22:55:51 < zyp> you've currently got (12-3)/5k6 = 1.6mA for the first step, but 3/1k5 = 2mA at the second step
2022-01-07T22:56:12 < zyp> and the second should be lower than the first, otherwise you're not hitting 3V at 12V in
2022-01-07T22:56:41 < zyp> increasing it to 2k will give you 1.5mA, leaving 0.1mA to pass through the zener
2022-01-07T22:58:07 < zyp> but you should run the numbers for the minimum and maximum input voltages as well
2022-01-07T22:58:38 < zyp> aiming for a high enough output voltage at minimum high input, and a not too high current at maximum input

2022-01-07T23:20:48 < catphish> zyp: you're right, i'm not happy with the values, i designed it so that at the maximum likely voltage (15v) the zener would not carry any current (i intended it only for TVS)
2022-01-07T23:21:31 < catphish> the downside is that 2v (the minimum logic high level) is only achieved at 10v input, which is very high
2022-01-07T23:22:03 < catphish> the other design i found uses 4.7k and 1.5k
2022-01-07T23:23:06 < catphish> this is really what motivated me to think about whether the low side resistor could be removed
2022-01-07T23:23:27 < catphish> but perhaps there's a compromise, a larger low side resistor, more current though the zener
2022-01-07T23:27:20 < zyp> decide how much current you want through the top side resistor first at min/max input voltage, derive the rest of the numbers from that

2022-01-07T23:44:45 < kakium69> catphish: automotive stuff usually works down to 8V

2022-01-07T23:45:10 < catphish> a 12v lead acid battery has no business being discharged to 8v :)
2022-01-07T23:45:22 < kakium69> cranking
2022-01-07T23:45:31 < catphish> makes sense
2022-01-07T23:45:33 < catphish> but that is indeed what i'd like it to work at
2022-01-07T23:47:11 < catphish> well, it would be nice if it worked at 3.3v to 16v
2022-01-07T23:47:19 < catphish> but i'll take 8+
2022-01-07T23:48:12 < kakium69> 3.3 to 16v - why?
2022-01-07T23:48:57 < catphish> it would be useful if it could be driven directly by another MCU, but far more likely it'll be driven by a +12 source, so 8-16 is fine
2022-01-07T23:49:14 < ventYl_> catphish: typical range for older automotive equipment is 10-16V, newer works within 8.5-ish to 16V, sometimes even higher
2022-01-07T23:51:25 < kakium69> catphish: i don't think you should do single ended mcu-2-mcu lines like that in automotive environment catphish
2022-01-07T23:53:51 < catphish> kakium69: no, i'm inclined to agree, it's very unlikey to be needed, just thinking of making it flexible, but in reality it's more important that it's reliable at 12v, so the original design is probably fine, but perhaps with resistor values that favour a slightly higher voltage at the MCU side and make use of the zener
2022-01-07T23:55:38 < kakium69> sometimes those single ended connections fail even on single pcb
2022-01-07T23:56:16 < catphish> 4.7k and 1.5k would be good down to 8.2v
2022-01-07T23:56:56 < kakium69> it's perfect
2022-01-07T23:58:01 < zyp> would they?
2022-01-07T23:58:06 < ventYl_> catphish: you also have to consider currents at that voltages, like if 12 is nominal, at 8, there will be 50% increase, at 6 you have twice the current and so. you probably have to shut the thing down way before you'd reach voltages low as 3.3V in order to prevent serious damage
2022-01-07T23:58:07 < catphish> and at the normal working voltages of 12.6v and 13.5v, it gives 3.0v and 3.3v
2022-01-07T23:59:00 < catphish> which is perfect, if the voltage rises above 13.5v (which would only be transient), the zener and MCU TVS will take care of it, i'm not sure why i didn't do this originally :)

2022-01-08T00:08:02 < Laurenceb> 50k for the inverter
2022-01-08T00:08:10 < kakium69> why not induction motor?
2022-01-08T00:08:24 < kakium69> average load is rather high?
2022-01-08T00:08:26 < ventYl_> why is it going mad? it loses sense of rotor position?
2022-01-08T00:08:33 < Laurenceb> permanent magnet is a bit more compact
2022-01-08T00:08:50 < kakium69> ventYl_: it runs out of cycles
2022-01-08T00:08:54 < Laurenceb> ventYl_ yeah, encoder is glitching due to simulink
2022-01-08T00:09:34 < ventYl_> ah now i recall
2022-01-08T00:10:05 < BrainDamage> ironically it'd be one of the cases where formal verification would help
2022-01-08T00:10:42 < BrainDamage> so you'd know if it's simulink's compilation of the code bad, or wrong assumptions
2022-01-08T00:10:50 < ventYl_> Laurenceb: advise simulink guy to connect ignition coil to handlebars of his scooter and program it to start firing impulses each time CPU load reaches 50% from inverter control loop itself
2022-01-08T00:11:56 < Laurenceb> BrainDamage: we know exactly what the issue is, its the simulink spi driver code, its arduino tier
2022-01-08T00:12:13 < Laurenceb> and it hogs the processor while it busy waits
2022-01-08T00:12:38 < BrainDamage> just have the cpu load directly control the duty cycle 
2022-01-08T00:12:51 < BrainDamage> higher load = higher voltage
2022-01-08T00:12:57 < kakium69> :O
2022-01-08T00:13:00 < zyp> let me just express a bit of happiness that I'm not working with simulink anymore
2022-01-08T00:13:25 < Laurenceb> we will probably rewrite it as interrupt/dma driven c code
2022-01-08T00:14:32 < ventYl_> i have learned that interrupts are not giving any major improvements with SPI if you need to shuffle a lot of data
2022-01-08T00:14:42 < ventYl_> but if there is a lot of busywaits you probably don't need to
2022-01-08T00:18:50 < kakium69> Laurenceb: radial or axial flux motor?
2022-01-08T00:19:07 < Laurenceb> radial
2022-01-08T00:21:50 < BrainDamage> retarded idea of the day: train where the motor wheels as nothing but reg pieces of metal, and supply is differential on the rails, and motion is through linear motor effect of the wheels shorting the rails
2022-01-08T00:22:04 < Laurenceb> lmao
2022-01-08T00:22:09 < zyp> train railgun?
2022-01-08T00:22:14 < BrainDamage> yep
2022-01-08T00:22:36 < catphish> jlcpcb are out of their basic 1uf 0603 :(
2022-01-08T00:23:05 < Laurenceb> we have a yard full of old London underground inverters and old car batteries on pallets to power this thing
2022-01-08T00:23:21 < BrainDamage> unlike railgun it doesn't suffer from friction inefficiency
2022-01-08T00:23:34 < BrainDamage> but it suffers from low flux linkage
2022-01-08T00:23:37 < Laurenceb> scary shit, it could literally vapourise someone
2022-01-08T00:23:45 < zyp> how much of the input power do you get out as motive force?
2022-01-08T00:24:07 < Laurenceb> close to 1MW, efficiency is >98%
2022-01-08T00:24:26 < zyp> I'm talking about railgun
2022-01-08T00:24:30 < Laurenceb> oh
2022-01-08T00:24:55 < zyp> stuff that actually works is less fun :p
2022-01-08T00:25:22 < BrainDamage> it'd have low efficiency unless you add sort of two halves of a E transformer
2022-01-08T00:25:34 < BrainDamage> to keep flux high
2022-01-08T00:25:53 < BrainDamage> but then you'll have problems of eddy losses
2022-01-08T00:26:13 < BrainDamage> and saturation
2022-01-08T00:26:24 < Laurenceb> we have high voltage three phase -> London underground inverters -> car batteries -> inverter -> motor
2022-01-08T00:26:38 < BrainDamage> you could keep saturation low since all wheels become engines
2022-01-08T00:26:44 < BrainDamage> which is a nice plus
2022-01-08T00:26:44 < Laurenceb> there is a fibre optic based safety interlock system to make it a bit less mental
2022-01-08T00:27:00 < Laurenceb> but it can still kill you very easily
2022-01-08T00:27:40 < BrainDamage> i'd eyeball 20-30% effic for the train railgun
2022-01-08T00:28:06 < BrainDamage> shit for practical things, maybe ok for a toy model
2022-01-08T00:29:24 < ventYl_> Laurenceb: no HIL kind of test before you run the shit with real toys?
2022-01-08T00:31:03 < BrainDamage> it'd have the nice adv tho that the only moving parts are the wheels
2022-01-08T00:31:22 < Laurenceb> ventYl_: only the escooter lol
2022-01-08T00:32:41 < ventYl_> Laurenceb: that's pretty shitty process for developing something such demanding on quality of the design
2022-01-08T00:32:51 < Laurenceb> ikr
2022-01-08T00:33:02 < Laurenceb> but muh simulink makes it ok
2022-01-08T00:33:59 < ventYl_> well, simulink's general effect is, that it makes things not managing to run on current HW
2022-01-08T00:34:12 < ventYl_> or, not simulink itself, rather than targetlink
2022-01-08T00:34:21 < ventYl_> I guess that's what you use to materialize your models
2022-01-08T01:01:21 < kakium69> escooter is fine
2022-01-08T01:01:29 < kakium69> you can take it to your desk
2022-01-08T01:01:49 < kakium69> train traction motor you don't
2022-01-08T01:08:16 < zyp> haven't heard about targetlink, IIRC we used simulink coder
2022-01-08T01:12:59 < ventYl_> zyp: it's dspace extension

2022-01-08T01:22:48 < ventYl_> it's mostly used in automotive aerospace and maybe military and railway I guess
2022-01-08T01:22:52 < ventYl_> and it sucks
2022-01-08T01:22:59 < ventYl_> that one probably google won't tell ya
2022-01-08T01:23:21 < zyp> that's okay, that's a given from the simulink relation
2022-01-08T01:23:38 < ventYl_> well, simulink is okay, if you do it for science
2022-01-08T01:23:58 < ventYl_> once you start using simulink by-products for production directly, it starts sucking massively
2022-01-08T01:24:11 < ventYl_> i've seen horrible things done using simulink

2022-01-08T18:37:46 <@karlp> zyp: the mmio magic naming enums gets grump about having AHB1: DMA1: and also C2AHB1:DMA1... type things :|
2022-01-08T18:37:53 <@karlp> tips or ideas on how you'd like to see it?
2022-01-08T18:38:02 <@karlp> I can prefix what i need with C2 again, but...
2022-01-08T18:38:44 <@karlp> and given that it becomes RCC.enable(rcc::DMA1) I guess that's probably only rational option?
2022-01-08T18:41:16 < zyp> it's kinda moot since those are for CPU2
2022-01-08T18:42:07 < zyp> but yeah, if you need them, a C2 prefix might be the most sensible option
2022-01-08T19:06:25 < catphish> v3 - this is actually getting boring now :) https://imgur.com/a/ljSe0A2

2022-01-08T19:55:24 < ventYl_> Laurenceb: have you also quantum-computing ready state machines there in your simulink software?
2022-01-08T19:55:35 < Laurenceb> lol
2022-01-08T19:55:56 < ventYl_> we had those
2022-01-08T19:57:30 < ventYl_> someone simply decided, that state machine will be a bitmask of states, so in theory, it could be in a superposition of multiple states at once

2022-01-08T22:45:14 <@karlp> that's  a real annoyance with winter here, not a chance of having reliable snow for any fun winter activities.
2022-01-08T22:46:48 < fenugrec> yea, it does need a good layer of snow. Although some people go on frozen lakes if you have those
2022-01-08T22:46:59 < fenugrec> but you guys have volcanos and shit. Can't have everything

2022-01-09T00:12:04 < catphish> i'd quite enjoy a snowy retreat, but not sure where to go, ideally somewhere with snow, log cabins, log fires, and internet!
2022-01-09T00:12:49 < kakium69> ah
2022-01-09T00:12:51 < kakium69> lapland
2022-01-09T00:13:09 < catphish> yeah that's been mentioned before, will look again
2022-01-09T00:14:04 < kakium69> if no plenty of reindeers required / etc. tourism things kuusamo could work
2022-01-09T00:14:56 < kakium69> but basically if you go from britland to finland plane lands to laplands
2022-01-09T00:15:56 < catphish> i don't really want tourism / reindeers / children, just a quiet woodland
2022-01-09T00:17:14 < catphish> might go away for christmas next year, entertained family this year, need something quieter / more personal next year!
2022-01-09T00:17:30 < catphish> we like log cabins and wildlife
2022-01-09T00:17:42 < catphish> but also netflix!
2022-01-09T00:25:36 < kakium69> wow nice looking big log cabins are 4000euros a week
2022-01-09T00:25:59 < kakium69> the nicest ones
2022-01-09T00:29:45 < catphish> yeah, no, i'm good for about 1kEUR a week
2022-01-09T00:29:48 < catphish> :)
2022-01-09T00:31:27 < kakium69> those things are castles
2022-01-09T00:31:30 < kakium69> not cabins
2022-01-09T00:33:22 < catphish> i stay at this place in the UK, it's nice, but no snow - https://loghouseholidays.co.uk/
2022-01-09T00:36:58 < catphish> this looks amazing, but the 4k a week pricetag :) https://www.theluxuryholidaycompany.com/destinations/europe/finland/accommodation/l7-luxury-lodge-finnish-lapland-153360
2022-01-09T00:37:35 < kakium69> how massive that thing is
2022-01-09T00:38:00 < kakium69> it has wings bigger than average cabin
2022-01-09T00:38:41 < catphish> yeah there's only 2 of us, i want something nice, but small!
2022-01-09T00:43:37 < kakium69> it seems when you go under 120m2 it gets rudimental
2022-01-09T00:45:48 < kakium69> but price doesn't reflect that as much as I expected
2022-01-09T00:46:51 < kakium69> https://www.lomarengas.fi/mokit/kuusamo-ruka-ski-chalet-finland-9973 :o
2022-01-09T00:47:42 < catphish> UK holiday sellers are very focused on family resorts, santa, ans reindeer
2022-01-09T00:47:55 < catphish> i basically want to avoid that stuff and find something cheap and quiet
2022-01-09T00:48:15 < catphish> ski chalet looks ideal though
2022-01-09T00:49:43 < catphish> grr someone already booked christmas 2022
2022-01-09T00:49:58 < kakium69> certainly
2022-01-09T00:50:10 < kakium69> and you pay double etc. for christmas
2022-01-09T00:50:15 < kakium69> and new year
2022-01-09T00:51:12 < catphish> that's absolutely perfect, but about twice as much as i'd like to pay, and twice the size i need
2022-01-09T00:51:22 < catphish> i'll try that website though
2022-01-09T00:53:03 < catphish> website is ideal, has lots of choice, just need to figure out where to go
2022-01-09T01:06:53 < zyp> friend's girlfriend's parents got a nice little cabin somewhere in the middle of nowhere in finland
2022-01-09T01:06:58 < zyp> no netflix though
2022-01-09T01:07:38 < fenugrec> if you take the trouble of heading out in the bush for vacation, why would you bring internet with you
2022-01-09T01:08:05 < zyp> yeah
2022-01-09T01:08:10 <@karlp> pros and cons of both.
2022-01-09T01:08:13 < kakium69> funlands have LTE basically everywhere besides national parks in north
2022-01-09T01:08:27 <@karlp> doing the _same_ as home? meh, having net for other stuff? still handy...
2022-01-09T01:08:45 <@karlp> daughter's been put in quarantine, we're fucking off the to summer house tomorrow to get out of the house.
2022-01-09T01:08:46 < zyp> but yeah, coverage were decent and we brought solar chargers for phones
2022-01-09T01:08:59 < zyp> (and I believe they got electricity the year after we were there)
2022-01-09T01:08:59 <@karlp> stillgoing to be happy with having ninterwebnet and netflix at the summerhouse

2022-01-09T01:09:52 < zyp> with LTE coverage pretty much anywhere, it's hard to find somewhere truly without netflix
2022-01-09T01:10:17 <@karlp> yeah, I got an LTE router for the summerhouse, 
2022-01-09T01:10:31 <@karlp> it actualyl has 5g coverage there, but I didn't feel like paying extra for that :)
2022-01-09T01:10:36 < qyx> karlp: no electricity there?

2022-01-09T01:11:10 < zyp> not when we went
2022-01-09T01:11:19 < zyp> but I believe they got it the year after
2022-01-09T01:11:25 <@karlp> kakium69: what's that scale in?
2022-01-09T01:11:29 < catphish> fenugrec: i can see the argument, but i *like* watching netflix, i don't find it incompatible with relaxing :)
2022-01-09T01:11:37 <@karlp> it makes no sense...

2022-01-09T01:11:57 <@karlp> of what, when you get first snow? or when you stop having the snow melt? or what?
2022-01-09T01:12:07 < kakium69> snow stays

2022-01-09T01:13:00 < qyx> yeah we were talking about holidays yesterday
2022-01-09T01:13:07 < catphish> the obvious answer is that netflix is only 10% of the day
2022-01-09T01:13:08 < qyx> with a friend of mine we used to do a lot of hiking
2022-01-09T01:13:21 < qyx> thigns changed considerably over the past 10 years

2022-01-09T01:13:48 < catphish> it's nice to watch tv before bed, but the rest of the day is spend enjoying the outside, or sleeping
2022-01-09T01:13:53 < qyx> I used to carry all the survival stuff and paper maps and such, now I wouldn't dare without a gps-enabled phone
2022-01-09T01:14:12 < catphish> gps really is magical
2022-01-09T01:14:20 < qyx> I got lost only once

2022-01-09T01:15:22 < catphish> kakium69: i tend to begin my search at Rovaniemi because it's easy to fly to, and reasonably north
2022-01-09T01:15:30 < qyx> it didn't help me much though
2022-01-09T01:15:35 < kakium69> karlp: statistically the day when snow starts to stick around

2022-01-09T01:19:58 <@karlp> that's actually less than I expected
2022-01-09T01:20:20 <@karlp> half decen californing ski resorts expect a base of ~2m before they even _start_
2022-01-09T01:20:22 < catphish> 400mm, that's DEEP
2022-01-09T01:20:29 < kakium69> yeah it's not hokaido
2022-01-09T01:20:34 < kakium69> or norway
2022-01-09T01:21:33 <@karlp> hrm, no, looks like 1m recently, with ~6-7m of snowfall over the season
2022-01-09T01:21:56 < catphish> https://www.lomarengas.fi/en/cottages/rovaniemi-siika-kama-kiviniemi-15171 << serious contender
2022-01-09T01:22:10 <@karlp> kakium69: but if that's solid pack depth, that's pretty reasonable, certainly good for kiting and snowmobiling and shit.
2022-01-09T01:22:31 <@karlp> we're lucky to get snow to even stick for more than a day or two here in the south
2022-01-09T01:27:02 -!- Guest2986 [~vit@chello085216193138.chello.sk] has quit [Quit: Konversation terminated!]
2022-01-09T01:27:35 < kakium69> catphish: neighbours both side 30meters
2022-01-09T01:28:25 < catphish> kakium69: yeah that's the only disadvantage, but i can probably live with it
2022-01-09T01:29:16 < catphish> how do you actually travel, are roads all passable?
2022-01-09T01:29:29 < catphish> in UK, when it snows even a little bit, we give up on driving
2022-01-09T01:30:55 < kakium69> road conditions are fine
2022-01-09T01:31:18 < kakium69> and winter tyres
2022-01-09T01:32:26 < kakium69> basically there is usually no difference between summer or winter
2022-01-09T01:34:20 < PaulFertser> In russia some places are much more accessible during the winter, cold and snow helps to build temporary roads for cheap.
2022-01-09T01:34:26 < kakium69> sometimes there is 5cm of fresh snow and you should reduce speed to keep braking distance
2022-01-09T01:34:54 < kakium69> sometimes 10cm but can be plowed through even with front wheel drive
2022-01-09T01:35:04 < kakium69> and next day it's all removed
2022-01-09T01:35:11 < kakium69> by next day*
2022-01-09T01:35:46 < kakium69> 10cm starts seriously affect average speed
2022-01-09T01:35:48 < PaulFertser> kakium69: how do you treat snow on pedestrian paths?
2022-01-09T01:36:33 < kakium69> small loader with plow
2022-01-09T01:36:41 < kakium69> and sander box behind the loader
2022-01-09T01:37:33 < PaulFertser> kakium69: in moscow they use plenty of salt to melt it on the roads and nearby.
2022-01-09T01:37:52 < kakium69> coastal cities do that here too
2022-01-09T01:38:07 < PaulFertser> Doesn't it damage boots and other property?
2022-01-09T01:38:12 < kakium69> cars
2022-01-09T01:38:15 < kakium69> cars go to shits
2022-01-09T01:38:56 < PaulFertser> You aren't supposed to drive the same car for more than 5 years anyway.
2022-01-09T01:39:26 < kakium69> 25years you mean?
2022-01-09T01:39:57 < kakium69> you forgot number 2
2022-01-09T01:40:45 < kakium69> coastal cities just dump salt because it goes to sea anyways and wont salt lands
2022-01-09T01:41:12 < kakium69> also they don't have snow problems but ice problems
2022-01-09T01:43:15 < kakium69> when they have snow problems they learned to dump snow in sea
2022-01-09T01:43:25 < kakium69> and mix it with sea water
2022-01-09T01:43:41 < PaulFertser> Interesting
2022-01-09T01:43:41 < kakium69> it just dissapears
2022-01-09T01:44:53 < kakium69> there is a shredder with sea water jets and a truck dumps it's load to that shredder
2022-01-09T01:47:15 < kakium69> it's rather new invention
2022-01-09T01:49:47 < catphish> kakium69: ideal, thanks, i might give it a go
2022-01-09T01:50:18 < kakium69> the shredder? :o
2022-01-09T01:50:28 < catphish> kakium69: the roads :)
2022-01-09T01:51:16 < catphish> kakium69: i'll be going to the north in mid winter and renting a car, so need to make sure i know what to expect"
2022-01-09T01:51:18 < catphish> *!
2022-01-09T01:51:39 < kakium69> traffic is on rigth side
2022-01-09T01:51:50 < catphish> nah, i'm british, we drive on left
2022-01-09T01:54:12 < catphish> https://www.youtube.com/watch?v=UyFwViOiAqY
2022-01-09T01:54:49 < kakium69> use electric engine block heater / cabin heater plug for 1hour or so, clean windscreen, windows, lights, plates from snow and ice
2022-01-09T01:55:16 < kakium69> always use driving lights and stay on right
2022-01-09T01:56:30 < catphish> my british sports car is woefully illequiped for even british winter, i'm rather looking forward to converting it to EV, the electric heating might have a chance at making it usable in the winter
2022-01-09T01:56:50 < catphish> i have no idea how one uses an electric block heater, we don't have such a thing
2022-01-09T01:57:07 < kakium69> car comes with weird plug thing
2022-01-09T01:57:19 < kakium69> front of the car has weird socket
2022-01-09T01:57:25 < catphish> you just plug in an hour before you drive?
2022-01-09T01:57:29 < kakium69> plug both ends
2022-01-09T01:57:51 < kakium69> or set a timer that is usually in car park socket
2022-01-09T01:58:26 < catphish> cabin says " 2 car heating sockets " to i guess i'm good
2022-01-09T01:59:05 < PaulFertser> kakium69: in what temperatures do you need to use the block heater?
2022-01-09T02:00:11 < kakium69> some say +5 and some say -5
2022-01-09T02:00:43 < PaulFertser> kakium69: for real? My car had no real issues starting in -25 without any preheating.
2022-01-09T02:01:22 < catphish> the coldest we have in southern UK is about -3 and cars have no problem at that temp
2022-01-09T02:01:24 < kakium69> I never preheat my junk
2022-01-09T02:02:01 < kakium69> PaulFertser: it's mainly for fuel economy and comfort + can reduce engine wear quite a lot
2022-01-09T02:02:02 < PaulFertser> kakium69: is that preheating needed when you use inappropriate engine oil? IDK, I have 10w40 in motorbike, no issues starting it around 0 degrees.
2022-01-09T02:02:27 < catphish> though i learned this week my car's door locks freeze at 0C and can't be opened :)
2022-01-09T02:02:38 <@karlp> heh, that was one of my memories of alaska: http://tweak.net.au/pics/2002/07-alaska/teaser82.jpg
2022-01-09T02:02:49 < PaulFertser> kakium69: I can understand that for when it's -15 probably, but needing it for -5? That's just odd.
2022-01-09T02:02:55 < catphish> i think there's a serious difference between modern cars and last-century ones
2022-01-09T02:02:59 <@karlp> catphish: that's probably just residual water.  get a hair dryer out and just try and get it dry once and you're good
2022-01-09T02:03:18 < kakium69> it's for optimizing fuel economy and preheating cabin (opt)
2022-01-09T02:03:21 < kakium69> PaulFertser
2022-01-09T02:03:39 < catphish> karlp: yeah, i got into the car through the passenger side, started the engine, and after a few minutes it was fine
2022-01-09T02:04:05 < PaulFertser> kakium69: how much fuel can one save that way?
2022-01-09T02:04:39 < kakium69> maybe half a litre or something
2022-01-09T02:04:40 < catphish> frankly my 2001 roadster should not be driving in subzero temps, but my idiot sister in law has borrowed my golf, so i'm stuck with it
2022-01-09T02:05:21 < PaulFertser> kakium69: I wonder how, does that assume you'd be on idle for like an hour?
2022-01-09T02:05:38 < kakium69> no
2022-01-09T02:05:58 < catphish> my golf can defrost and demist itself in about 2 minutes
2022-01-09T02:06:10 < catphish> the sports car, not so much :)
2022-01-09T02:06:35 < catphish> EV conversion will do it good!
2022-01-09T02:06:44 < kakium69> some vw's have electric heater that turns on when car is started catphish
2022-01-09T02:06:57 < kakium69> glow plug in coolant line
2022-01-09T02:07:00 < kakium69> basically
2022-01-09T02:07:27 < catphish> kakium69: i suspect my golf has some electric heating, it warms up much faster than the engine does
2022-01-09T02:07:39 < kakium69> audi a4 2001 starts defrosting windscreen from start
2022-01-09T02:07:51 < kakium69> passat 2001 doesnt
2022-01-09T02:08:09 < catphish> my golf is 2012, its ability to work in winter is amazing, i assume electric heating
2022-01-09T02:08:20 <@karlp> 2015 skoda hot air blasts the windscreen _fast_
2022-01-09T02:08:33 < catphish> which is why i suspect my 2001 roadster will benefit hugely from electric heating
2022-01-09T02:08:46 <@karlp> not as fast as the 2006? focus with electric elements in the windscreen, but wayyyyyy faster than the 2001 micra and the 98 patrol ever could.
2022-01-09T02:08:55 < catphish> it takes about 10 minutes to warm up, and can barely demist the windscreen even then
2022-01-09T02:09:13 < catphish> i have good news...
2022-01-09T02:09:15 <@karlp> what I realllllly miss is electric heated steering wheel
2022-01-09T02:09:27 <@karlp> I presume thatmust still be patent protected?
2022-01-09T02:09:42 < catphish> since 9 minutes ago, it's my birthday, i'm 35!
2022-01-09T02:09:50 <@karlp> congratulations!
2022-01-09T02:09:53 < kakium69> happy birthday!
2022-01-09T02:10:03 < catphish> thanks! :)
2022-01-09T02:11:06 < kakium69> PaulFertser: see "Defa Termini 2100"
2022-01-09T02:13:07 < kakium69> let that thing do it's thing inside a cabin for a hour and all the windows are cleared from snow and ice too
2022-01-09T02:14:26 < PaulFertser> 2100 / 13 = 161 A
2022-01-09T02:14:27 < kakium69> if not usually it's already like floating just push it off or just start windshield wipers and stuff flies off
2022-01-09T02:14:33 <@karlp> catphish: https://nc.beeroclock.net/s/9AHeJcfx4yZ684E
2022-01-09T02:15:05 < kakium69> PaulFertser: it's mains connected if you have block heater with y-harness and cabin mains plug
2022-01-09T02:15:48 < kakium69> my junk doesn't so fuk preheat
2022-01-09T02:15:49 < PaulFertser> kakium69: ah, I see. You're used to having cars outside close to power sources.
2022-01-09T02:16:06 < kakium69> yes
2022-01-09T02:16:23 < kakium69> socket per car slot
2022-01-09T02:18:12 < catphish> karlp: good idea, i'm past wine time into "sleep now" time, but i'm sure i'll celebrate tomorrow :)
2022-01-09T02:18:31 < PaulFertser> kakium69: is electricity cheaper than petrol? There're devices like Eberspacher or Webasto.
2022-01-09T02:19:03 < kakium69> definitelly it at least was
2022-01-09T02:19:07 < catphish> electricity is definitely cheaper than petrol (based on car efficiency)
2022-01-09T02:19:42 < catphish> though this is probably only true if one buys that electricity at low demand hours
2022-01-09T02:19:48 < PaulFertser> catphish: comparing special heaters like those I mentioned?
2022-01-09T02:19:58 < PaulFertser> Or running the car
2022-01-09T02:20:12 < kakium69> 2eur/litre
2022-01-09T02:20:45 < catphish> PaulFertser: in theory, electricity should be cheaper, though my comparison was based on turning it into motion, not heat, so i'm not certain
2022-01-09T02:21:46 < kakium69> ICE engine puts most energy into exhaust
2022-01-09T02:21:54 < kakium69> not even coolant
2022-01-09T02:22:00 < kakium69> but exhaust
2022-01-09T02:22:39 < kakium69> at least gasoline engine idk about diesel
2022-01-09T02:23:06 < PaulFertser> catphish: I see. Those heaters are not needed for the most parts of Europe anyway
2022-01-09T02:23:24 < PaulFertser> kakium69: that's why y'all got those turbines to extract some of it?
2022-01-09T02:23:52 < kakium69> ye
2022-01-09T02:23:53 < catphish> kakium69: are they *that* inefficient?
2022-01-09T02:24:40 < fenugrec> at the end of a combustion cycle, you don't have much pressure left, but still a bunch of heat, and it's hard to transfer that heat to anything usable
2022-01-09T02:25:07 < kakium69> heat and hydrocarbons
2022-01-09T02:25:25 < fenugrec> well after a cat hopefully not too many HCs P )
2022-01-09T02:25:40 < kakium69> and even cats get white hot
2022-01-09T02:25:50 < fenugrec> I was going to say - more unusable heat !
2022-01-09T02:25:59 < kakium69> they use that now
2022-01-09T02:26:17 < kakium69> vw has all kinds of weird exhaust coolant things
2022-01-09T02:26:34 < kakium69> but only used to bring engine to operating temperature
2022-01-09T02:26:38 < fenugrec> interesting, didn't think it'd be worth it in a car
2022-01-09T02:27:10 < fenugrec> *worth the complexity etc
2022-01-09T02:28:22 < kakium69> litre of gasoline has 10kwh
2022-01-09T02:28:55 < fenugrec> .8kg * 44MJ/g... sounds about right
2022-01-09T02:29:14 < fenugrec> MJ/kg
2022-01-09T02:29:47 < kakium69> lets assume webasto/eber has efficiency of 50%
2022-01-09T02:29:57 < kakium69> gasoline price is 2eur
2022-01-09T02:30:01 < fenugrec> karlp, you had a bone to pick with the lm1117 or what P)
2022-01-09T02:30:10 < kakium69> 20cents per kwh of car heating
2022-01-09T02:30:52 < fenugrec> do you factor in that some LDOs have "special needs" re i/o filtering caps
2022-01-09T02:31:28 < kakium69> current electricity price without transfer ~15cents
2022-01-09T02:31:53 < kakium69> damn it's cheaper to heat with gasoline atm. PaulFertser
2022-01-09T02:32:40 < kakium69> usually electricity goes around 5-10cents but not anymore
2022-01-09T02:33:04 < kakium69> it used to be 15cents flat rate with transfer
2022-01-09T02:33:15 < kakium69> or less
2022-01-09T02:33:26 < kakium69> 12
2022-01-09T02:38:30 < kakium69> sorry 40cents per kwh of car heating

2022-01-09T16:08:17 < Xogium> heh I found another guy who's totally blind and wanted to do soldering
2022-01-09T16:09:24 < Xogium> so he went on a forum and asked people for suggestions, and the 10 first replies or so were like, forget it man, you can't do it… Then people somehow regained enough common sense to figure out that maybe it could be done and started to suggest things, even hot air guns
2022-01-09T16:09:48 < Xogium> but in the end, I think he gave up on it, his last messages is, I'll look at it
2022-01-09T16:09:54 < Xogium> and that was over 2 years ago
2022-01-09T16:10:54 < Xogium> they didn't even say it like, it might be very difficult to do but hat's off for trying
2022-01-09T16:11:05 < Xogium> they litterally said, you can't do this blind
2022-01-09T16:11:22 < Xogium> that's so rude
2022-01-09T16:12:15 < PaulFertser> Depends on what kind of soldering I guess.
2022-01-09T16:12:18 < b-rex> to be fair, if you aren't blind, soldering seems impossible.
2022-01-09T16:12:32 < Xogium> at any rate, he dismissed the hot air guns, that much I know. Definitely not good when blind apparently, aside from the cold/heat issues
2022-01-09T16:12:36 < b-rex> i can't think of anything i could do to sucessfully solder something if i was blind.
2022-01-09T16:13:12 < PaulFertser> If you just want to solder two wires or add PLS to a board, doable with soldering paste and hot air, why not?
2022-01-09T16:13:23 < Xogium> b-rex: yeah I know. But at least, they could say it with a bit more… What's the word ? Tact ?
2022-01-09T16:13:54 < Xogium> PaulFertser: in my case I wanted to attach gpio pins to a board ;)
2022-01-09T16:14:06 < b-rex> you mean like the gpio headers?
2022-01-09T16:14:12 < Xogium> yea
2022-01-09T16:14:17 < PaulFertser> Xogium: using hot air for that is probably possible
2022-01-09T16:15:10 < Xogium> bought the boards and learned they came with unsoldered headers on the day they arrived. Apparently, it was displayed in the picture…
2022-01-09T16:15:10 < PaulFertser> Xogium: also, it's a rather quick job (like 5 minutes) for anyone sighted, surely you meet non-blind people often enough?
2022-01-09T16:16:17 < Xogium> PaulFertser: well I have neighbors… meet them sometimes when I go check for mails, that kind of stuff
2022-01-09T16:17:07 < Xogium> it's just confusing me how much some people will tell you soldering isn't easy even when sighted and others claim it's easy
2022-01-09T16:18:09 < PaulFertser> Xogium: I think with some training it's possible to solder through hole without seeing. I can imagine using SMD solder paste to fill the holes, then you wipe out the excess, then you insert the pins and hot air them. Kinda pin-in-paste ad-hoc. Doable if someone who knows what he or she is doing develops the procedure and then teaches you.
2022-01-09T16:18:59 < PaulFertser> Xogium: soldering can be very different. Through hole 2.54 is trivial, I could teach a 6-years old to do that in 30 minutes I guess.
2022-01-09T16:21:51 < Xogium> it's just I keep getting lots of contradicting info, I guess
2022-01-09T16:21:55 < b-rex> i think using an iron and solder would be doable for gpio headers
2022-01-09T16:22:30 < PaulFertser> Xogium: details matter. Soldering 0402 SMD parts or fine-pitched ICs requires more skill.
2022-01-09T16:22:58 < b-rex> if the sighted assistant soldered one first, let it cool down, and let you feel the difference between an unsoldered header on the PCB and a soldered.
2022-01-09T16:23:17 < PaulFertser> Xogium: GPIO headers is trivial, if a friend comes to visit you and he or she never soldered, it can be done after watching basic lessons on youtube without much effort given you have the tools.

2022-01-09T16:24:09 < PaulFertser> b-rex: soldering iron without eye-hand coordination is almost impossible I think. Well, I can imagine tricks...
2022-01-09T16:24:28 < Xogium> well, I don't have any soldering iron or whatever, I never bought considering I keep hitting up and down as to if it's even doable or not
2022-01-09T16:24:49 < b-rex> PaulFertser: it's doable because you can feel the pins through the soldering iron. with a head, it's easy to navigate down the row of pins by feel.
2022-01-09T16:24:58 < b-rex> *header
2022-01-09T16:25:03 < PaulFertser> b-rex: e.g. one can find the pin to solder with a finger and hold a toothpick against it, holding it with fingers from the other side, then using that toothpick to guide the iron tip.
2022-01-09T16:25:16 < b-rex> PaulFertser: yes
2022-01-09T16:26:07 < PaulFertser> b-rex: or one can find the pin with a cold soldering iron, then turn it on and use a toothpick to feel when the solder starts to melt.
2022-01-09T16:26:36 < b-rex> PaulFertser: tbh, you can feel that too.
2022-01-09T16:27:04 < PaulFertser> And one can cut the needed amount of solder in advance, like 1 mm from a solder wire, shove it near the pin in the hole.
2022-01-09T16:27:55 < PaulFertser> b-rex: hm, yes, I guess, and you'll feel it's not sticking at all first, then it might become a bit sticky, then it'll be moving freely again, and you know you can turn it off.
2022-01-09T16:28:25 < PaulFertser> Hot air should be much easier.
2022-01-09T16:29:29 < b-rex> PaulFertser: yes and you could determine how much solder you've deposited as well. this is doable for a non-sighted person with some help. i know this from experience because i welded for years many times i didn't have the physical space or "view" to use a hood.
2022-01-09T16:29:32 < PaulFertser> Xogium: in any case I'm afraid you can't really self-teach it, you'll need someone to evaluate the results to suggest process improvements.
2022-01-09T16:30:21 < b-rex> e.g. welding 100s of bolts on the sides of boilers for large plates to hang over them. it was easier to just look the other way and close your eyes.
2022-01-09T16:30:39 < b-rex> you had to learn to feel what welding them is like
2022-01-09T16:30:44 < PaulFertser> b-rex: gas welding or current electrode welding?
2022-01-09T16:30:50 < b-rex> PaulFertser: stick welding
2022-01-09T16:31:02 < b-rex> thus i think this could translate to soldering... just a much smaller scale
2022-01-09T16:31:17 < b-rex> especially if one is blind, they often have enhanced other senses
2022-01-09T16:31:46 < PaulFertser> b-rex: sounds like it
2022-01-09T16:35:12 < Xogium> PaulFertser: yeah… Too bad there's no tech lab nearby, I guess
2022-01-09T16:37:16 < PaulFertser> Xogium: indeed. But I can only reiterate that normal 2.54 mm pin headers can be soldered by just about anybody after minimal "youtube training", no need to be techy for that.
2022-01-09T16:39:17 < Xogium> I suppose I'll have to bother my friend next time he comes over…
2022-01-09T16:39:46 < PaulFertser> Xogium: yep, just pre-plan so that there would be a soldering iron, flux and solder available.
2022-01-09T16:40:33 < Xogium> yeah… I don't know what to get yet
2022-01-09T16:40:49 < PaulFertser> Xogium: might also make sense to get some veroboard or similar and extra PLS pins for training, they're cheap.
2022-01-09T16:42:16 < Xogium> are they like pin strips like I got with my boards ?
2022-01-09T16:42:17 < PaulFertser> Xogium: for a job like this any 20--40 W soldering iron should do. Cheap flux too, just shouldn't be acidic. Probably the easiest would be to get solder as a wire with flux core, but I prefer to have liquid flux handy.
2022-01-09T16:42:58 < PaulFertser> Xogium: yes, pin strips. And some prototyping board with holes so that one can do few tests prior to soldering the real tihng.
2022-01-09T16:43:32 < PaulFertser> Xogium: I think if you say what shop you'd be using to buy it somebody here will be happy to find the right items for you.
2022-01-09T16:44:17 < fenugrec> *links to the most expensive metcal station available*
2022-01-09T16:44:32 < Xogium> hmm I ususally stick to mouser… I don't know any other reseller that are as accessible in their web ui
2022-01-09T16:44:37 < Xogium> but maybe there are
2022-01-09T16:44:54 < Xogium> ;)
2022-01-09T16:44:57 < PaulFertser> What about amazon?
2022-01-09T16:45:28 < Xogium> hmm could work but I have no real experience using it
2022-01-09T16:46:23 < PaulFertser> Probably your friend can order then?
2022-01-09T16:49:42 < Xogium> yeah
2022-01-09T16:50:45 < PaulFertser> Xogium: so probably amazon for your country is the easiest way then. Where are you again?
2022-01-09T16:50:59 < Xogium> france :)

2022-01-09T18:32:24 <@karlp> if you're just soldering headers on, use normal flux cored solder, dont bother with extra flux, you're just making it more complicated.
2022-01-09T18:34:44 < Xogium> honestly lots of stuff sounds complicated, gotta keep tip of iron wet with flux, gotta have sponges to wipe it…
2022-01-09T18:36:07 <@karlp> nah, fuck that.
2022-01-09T18:36:23 <@karlp> that stuff only matters ifoure doing stuff over and over for years and want thing to be beautfiul
2022-01-09T18:36:41 <@karlp> just nuke the pins with solder, no problems.
2022-01-09T18:37:35 <@karlp> get the soldering iron on the pin, get the solder wire straight and poke it at the join, when you feel it give as it melts, push in another bit more, then release solder, then iron.
2022-01-09T18:38:01 <@karlp> for doing strips of pin headers should be reasonably straightforward.
2022-01-09T18:38:24 <@karlp> but yeah, any sort of assembly sounds like it could get complicated quickly...
2022-01-09T18:39:07 < Xogium> yeah… honestly even this hurts my head

2022-01-09T18:40:23 <@karlp> that page s very much overthinking tings :)
2022-01-09T18:41:00 < Xogium> it is litterally the only guide there is I could find on soldering blind so… That's why I tried to follow it

2022-01-09T18:42:59 < Xogium> honestly it makes it feel like a gigantic mountin
2022-01-09T18:44:19 < PaulFertser> "Molten solder acts as a solvent--it dissolves metal from
2022-01-09T18:44:22 < PaulFertser> the surface of the pieces being joined" seriously?
2022-01-09T18:45:29 < qyx> yes your soldering iron tip too
2022-01-09T18:45:39 < qyx> if cheap chink made
2022-01-09T18:46:20 < qyx> that's why tips are not fully copper
2022-01-09T18:47:27 < Xogium> so I mean I honestly want to learn, but this is waaaay too much information in one go, and having noone to help me learn doesn't help matters
2022-01-09T18:49:30 < PaulFertser> qyx: some tips are fully copper, that's quite usable actually.
2022-01-09T18:55:51 < zyp> solder tips are plated
2022-01-09T18:56:27 < zyp> once you wear through the plating, it'll eat the rest of the tip quickly
2022-01-09T18:59:02 < PaulFertser> Older irons had copper rods for tip.
2022-01-09T19:01:02 < Xogium> yes it is even mentioned in the guide actually
2022-01-09T19:02:10 < Xogium> but they wear out quicket
2022-01-09T19:02:15 < Xogium> *quicker
2022-01-09T19:03:32 < PaulFertser> It's actually not that fast for occassional usage.
2022-01-09T19:04:36 < Xogium> but yeah it is honestly way too much info to absorb especially without anyone to teach
2022-01-09T19:05:11 < Xogium> the lighthouse for the blind only did one soldering workshop back in 2016, iirc. Was for $300
2022-01-09T19:06:26 < PaulFertser> Xogium: yes, that guide is way too long

2022-01-10T14:49:25 < BrainDamage> here sunsets become purpleish
2022-01-10T14:51:14 < Steffanx> Due to the ash/whatever the volcano is spewing, not the air planed I assume?
2022-01-10T14:53:33 < jadew> BrainDamage, yeah, it's about how you calculate the minimum required things, in order to get something to work.
2022-01-10T14:53:50 < BrainDamage> yes, volcano ash

2022-01-10T14:54:32 < jpa-> heh, apparently ST factory delivery dates for some STM32 models are now in December 2027 :D
2022-01-10T14:54:43 < Xogium> oww
2022-01-10T14:55:21 < ventYl_> soon
2022-01-10T14:55:33 < jpa-> if ST doesn't get their act together, GD32 is going to totally conquer the market
2022-01-10T14:55:56 < jpa-> [X] better vendor lib  [X] cheaper  [X] you can actually buy it
2022-01-10T14:57:00 < Xogium> thought gd32 was riskc-v
2022-01-10T14:57:05 < Xogium> er risc-v
2022-01-10T14:57:24 < Xogium> though I suppose risk-v works too ;)
2022-01-10T14:58:19 < jpa-> there are ARM GD32 models and RISC-V GD32 models
2022-01-10T14:58:21 < kakium69> buying markets clean from semiconductors is better profit than stock market gambling
2022-01-10T14:58:44 < Xogium> ah, so there's both… interesting
2022-01-10T14:58:45 < jpa-> apparently it makes pretty little difference to the user, as the peripherals are mostly compatible and you just use a different compiler
2022-01-10T15:00:44 < Xogium> their website kind of suck for accessibility though
2022-01-10T15:01:05 < Xogium> what am I supposed to make from a image that says, untitled-9
2022-01-10T15:01:27 < jpa-> is ST site good for blind? because it certainly isn't good for the seeing :D
2022-01-10T15:01:45 < Xogium> I wouldn't say, good… But certainly better than this one appears to be
2022-01-10T15:02:33 < Xogium> there's untilted images and also strange ones that say segger_sm andsmh_sm
2022-01-10T15:02:50 < Xogium> er typoes, sorry about that
2022-01-10T15:05:01 < ventYl_> well, long-term viability of GD32 depends on two factors (1) if they manage not to fuck up random stuff not because it is hard, just because they can (2) their products will be available for years, sometimes even decades
2022-01-10T15:05:36 < Xogium> heh
2022-01-10T15:06:22 < ventYl_> that's actually sad
2022-01-10T15:07:06 < Xogium> that sort of reminds me of that $9 computer called CHIP and the company that totally failed at delivering. I have no idea what happened, they lost their mind I guess. They went crazy because they had a bit over 2 million in the bank, started on design of other products while they hadn't even finished the batch of preordered CHIPs
2022-01-10T15:07:12 < ventYl_> i've seen many times, that random chinesium had some complicated part resembled and fully functional, yet it's purpose was fucked up by 30 second operation literally costing nothing
2022-01-10T15:07:13 < Xogium> from the kickstarter pledges
2022-01-10T15:09:37 < jpa-> ventYl_: yeah, GD32 has same kind of fuckups, like not documenting that their DFU bootloader only works well at 25 MHz crystal freq
2022-01-10T15:09:51 < Xogium> nasty

2022-01-10T15:33:05 < ventYl_> same applies for the rest of chineese RISC-V lineup, GD32V is far the best of them, yet still so bad I'd probably not want to use it in production environment
2022-01-10T15:33:38 < qyx> no?
2022-01-10T15:34:37 < ventYl_> well for me specifically there's a problem with CPU core configuration
2022-01-10T15:34:53 < ventYl_> yet it is still ESP8266-kind-of-flaky
2022-01-10T15:37:35 <@karlp> what do you mean, like concretely?

2022-01-10T15:49:39 <@karlp> what flakiness are you meanting
2022-01-10T15:50:14 <@karlp> and what's "problem with cpu config" mean?
2022-01-10T15:52:06 < ventYl_> GD32V does not contain memory protection unit
2022-01-10T15:52:48 < mawk> you don't need a mpu
2022-01-10T15:52:52 < mawk> you're getting pwned in any case
2022-01-10T15:52:55 < mawk> just do regular code
2022-01-10T15:53:06 < mawk> it's the zen approach to computer security
2022-01-10T15:53:35 < ventYl_> yeah, because i386 linear flat address mode in MS-DOS is all we really need :)
2022-01-10T15:53:48 < mawk> a mpu won't help you with that
2022-01-10T15:53:51 < mawk> it's not a full blown mmu
2022-01-10T15:54:33 < ventYl_> that's the matter just from memory model POV
2022-01-10T15:54:39 < ventYl_> MPU still can be vastly useful
2022-01-10T15:55:12 < kakium69> isn't main use of MPU to catch stack overflow?
2022-01-10T15:55:39 < ventYl_> that's one good use, actually first one which paid off then I implemented it
2022-01-10T15:56:42 < ventYl_> also rogue reads and writes, which don't get stopped by bus errors
2022-01-10T15:56:58 < ventYl_> pretty much regardless of reason they are performed
2022-01-10T15:58:08 < PaulFertser> When one RTOS task happens to write to another's data it might be nasty to debug.
2022-01-10T15:58:26 <@karlp> is there something else? I mena, I get that you like the MPU but for the other million o fus who aren't using it on CM3 anyway, is there anything else that was "flaky" ?
2022-01-10T15:58:28 < ventYl_> s/might/will be/
2022-01-10T15:59:31 < PaulFertser> ventYl_: well, in one case I remember having debugged personally it wasn't too bad, once I saw some variable gets damaged somehow I just put a watchpoint on it and saw the offender.
2022-01-10T15:59:52 < PaulFertser> ventYl_: in another the damage was over DMA so not sure if MPU could help there.
2022-01-10T16:00:44 < ventYl_> depends on DMA implementation, some have protection extensions, some don't

2022-01-10T16:04:49 < ventYl_> karlp: sorry, I reviewed several cores back then and don't remember what exactly applies to which exact RISC-V-based MPU/SoC. i just remember certain details, it is also possible that over time things have changed
2022-01-10T16:05:39 < qyx> did you try to do anything with the sifive thing from pine?
2022-01-10T16:05:59 < qyx> idk where do I put it

2022-01-10T16:06:06 < ventYl_> not yet
2022-01-10T16:06:38 < ventYl_> I expect it also being flaky, at least the core itself has MPU so it makes sense to spend some time with it for me

2022-01-10T16:18:46 < ventYl_> karlp: well, understood. and I am not selling it as anything else than my opinion strongly influenced by my specific use-case scenario
2022-01-10T16:19:20 < PaulFertser> ventYl_: would be interesting to hear more details about specific issues you faced.
2022-01-10T16:19:34 < ventYl_> moreover as I've been searching for RISC-V based target which could serve me as a potential target for porting my RTOS, CPU configuration was a primary issue for me
2022-01-10T16:19:51 < PaulFertser> So far you mentioned lack of MPU, but what else?
2022-01-10T16:20:09 < ventYl_> PaulFertser: well, in a nutshell, IIRC none of chineese RISC-Vs has MPU, pretty much the only implementation a mortal being can buy which has one are SiFive cores
2022-01-10T16:21:00 < ventYl_> then, one company website no longer exists under old name, they have renamed themselves with no redirect from old hostname, after you dig up the new name, you realize that only one of their chips actually has datasheet available
2022-01-10T16:21:04 < ventYl_> which is of questionable quality

2022-01-10T17:45:43 < Xogium> got my pack of big badass usb-c to usb-c cables from adafruit
2022-01-10T17:45:51 < Xogium> now that's what I call good cable
2022-01-10T17:45:59 < Xogium> can push 5A of power through
2022-01-10T17:49:01 < Xogium> even when I use them on my pc it will be better. I was sick of android saying 'slow charging'. Now it says fast charging
2022-01-10T17:49:06 < Xogium> and lsusb says
2022-01-10T17:49:11 < Xogium> MaxPower              896mA
2022-01-10T17:49:14 < Xogium> that's more like it

2022-01-10T18:44:06 < Laurenceb> not sure I trust L4 to keep the private key secure
2022-01-10T18:44:53 < Laurenceb> I'd probably trust a smartcard more

2022-01-10T18:45:33 <@karlp> they're both broken aiui,

2022-01-10T18:52:26 < Laurenceb> if its like other STM32, I bet L4 can be cracked by power glitching
2022-01-10T18:53:44 < Xogium> I don't know where is the usb plug on it rofl
2022-01-10T18:54:08 < Laurenceb> you plug _it_ into the usb
2022-01-10T18:54:19 < Xogium> yeah but surely there is one way ?
2022-01-10T18:54:23 < Xogium> like
2022-01-10T18:54:49 < Xogium> the end closest to the chip ot the slightly oval shaped end ?
2022-01-10T18:54:55 < Laurenceb> yeah
2022-01-10T18:54:55 < Xogium> or
2022-01-10T18:55:32 < Xogium> so oval end ?
2022-01-10T19:00:40 < Xogium> one thing is certain, I bet once it's in there, there is no way it gets out
2022-01-10T19:01:31 < Laurenceb> thats what she said
2022-01-10T19:01:37 < Xogium> hah
2022-01-10T19:02:03 < Xogium> I just don't want to insert it wrong because if I do then it will be very hard to get it out, I think
2022-01-10T19:02:20 < Xogium> it's tiny as hell and will be very difficult to grab
2022-01-10T19:03:27 < Xogium> but that said what did you mean about l4 and power glitching ?
2022-01-10T19:03:47 < Xogium> anything I could try for the fun of it ? I have both the locked and unlocked version of this thing
2022-01-10T19:04:51 < Xogium> also have the bigger form factor, the solo. Honestly the somu is probably way too small

2022-01-10T19:33:39 < Xogium> ok so now I'm confused
2022-01-10T19:34:00 < Xogium> if I get a power supply that uses iec320-c8 socket
2022-01-10T19:34:14 < Xogium> what cable should I get ? c7, or c9 ?
2022-01-10T19:36:16 < Xogium> its a switching psu that has power brick, not ending in a wall wort I think is the word
2022-01-10T19:36:43 < Xogium> so it has pins for socket c8 at one end
2022-01-10T19:37:05 < Steffanx> C7
2022-01-10T19:37:21 < Xogium> then… uh… this cable should work
2022-01-10T19:37:25 < Xogium> I think
2022-01-10T19:37:48 < Xogium> this is the psu https://www.mouser.fr/ProductDetail/418-TR36M120-11G02VI
2022-01-10T19:38:10 < Xogium> and the cable I got
2022-01-10T19:38:12 < Xogium> https://www.mouser.fr/ProductDetail/552-AC15WEU-R
2022-01-10T19:39:08 < Xogium> yet… unless I'm required to apply a whole lot of force, this doesn't fit in the socket
2022-01-10T19:39:12 < Xogium> I'm kinda puzzled
2022-01-10T19:52:10 < Xogium> yeah I really don't get this cable
2022-01-10T19:55:07 < Xogium> I'm guessing the socket is too short for the pins or something

2022-01-10T21:18:38 < mawk> use the header I said Laurenceb 
2022-01-10T21:18:42 < mawk> Connection: close
2022-01-10T21:18:44 < Laurenceb> mawk: I can see how to set a timeout on the socket, but that wont directly control how long the https POST takes
2022-01-10T21:18:54 < mawk> yes, so don't do it
2022-01-10T21:19:02 < mawk> do it at the http level
2022-01-10T21:19:07 < mawk> with the header I said

2022-01-10T21:19:17 -!- specing_ is now known as specing
2022-01-10T21:19:24 < mawk> it's a feature of http/1.1 to stay open
2022-01-10T21:19:24 < Laurenceb> ok I'll read.. I'm using c atm tho not c++
2022-01-10T21:19:39 < mawk> yeah it doesn't matter, you can set headers in your http client
2022-01-10T21:19:41 < Laurenceb> oh ok I get you now
2022-01-10T21:19:43 < Laurenceb> cool
2022-01-10T21:19:49 < Laurenceb> yeah this seems much more sane
2022-01-10T21:20:22 < Laurenceb> I need to learn http
2022-01-10T21:21:56 < Laurenceb> we have a fancy WAN system on hyperloop but sometimes it partially drops the connection in a nasty way, so the https post thread stays running for as long as 3minutes, causing large telemetry lags
2022-01-10T21:22:37 < Laurenceb> I'm going to make it quit and retry 10s later if that happens
2022-01-10T21:26:52 < Laurenceb> hmm but thats at the http level, I want to control the ssl functions directly
2022-01-10T21:27:58 < mawk> why
2022-01-10T21:28:04 < mawk> http server decides when to close the connection
2022-01-10T21:28:10 < mawk> you don't have to do anything at the ssl level
2022-01-10T21:28:15 < mawk> ssl is a dumb socket
2022-01-10T21:28:17 < mawk> that's all
2022-01-10T21:28:47 < mawk> if you do Connection:close then the connection will be closed when it's done
2022-01-10T21:28:57 < PaulFertser> mawk: hey. Do you by any chance fancy choosing a simple soldering iron, flux core solder, prototype board and PLS strip on french Amazon for Xogium? The idea is that the next time a sighted friend comes there would be some equipment to self-teach soldering enough to populate GPIO pin headers on one of the boards Xogium has.
2022-01-10T21:28:57 < Laurenceb> I dont think it will be reliable if I try to use the server to control the client
2022-01-10T21:29:32 < mawk> it's the client that does that Laurenceb 
2022-01-10T21:29:37 < mawk> send that header
2022-01-10T21:29:43 < mawk> I'm not sure who closes the socket, probably client
2022-01-10T21:29:50 < mawk> anyway it doesn't matter a lot, it will work
2022-01-10T21:30:01 < mawk> yes PaulFertser I can do that indeed
2022-01-10T21:30:07 < mawk> what is PLS strip?
2022-01-10T21:30:11 < Laurenceb> maybe I could use signals
2022-01-10T21:30:23 < mawk> maybe you could just try what I say Laurenceb lol
2022-01-10T21:30:28 < PaulFertser> mawk: 2.54 mm spaced pins in plastic
2022-01-10T21:30:29 < Laurenceb> so the thread gets a signal that causes everything to abort
2022-01-10T21:30:35 < mawk> that's the standard thing to make a connection close when it's done
2022-01-10T21:30:50 < Laurenceb> mawk: yeah but I'm on an unreliable connection
2022-01-10T21:30:56 < ventYl_> mawk: unless client advertises that it is going to send X bytes of data and sends X-Y bytes, then server may still wait for the remainder

2022-01-10T21:31:16 < mawk> it's not unreliable
2022-01-10T21:31:20 < mawk> well have a timeout if you want

2022-01-10T21:31:42 < Laurenceb> sometimes (few times a day) it gets really intermittent
2022-01-10T21:31:45 < Laurenceb> sure
2022-01-10T21:31:49 < mawk> you use tcp, so all data that comes through is good
2022-01-10T21:32:04 < mawk> so just let the connection open so it tries again and finishes sending the data
2022-01-10T21:32:05 < Laurenceb> yeah but it can have seconds to tens of seconds of lag
2022-01-10T21:32:05 < mawk> no?
2022-01-10T21:32:08 < mawk> yeah
2022-01-10T21:32:16 < mawk> but then closing the connection and trying again won't do any more good
2022-01-10T21:32:24 < mawk> except the data will be fresher maybe
2022-01-10T21:32:31 < mawk> yeah indeed ventYl_ 
2022-01-10T21:32:50 < Laurenceb> it makes the interface with the system easier maybe...
2022-01-10T21:33:08 < Laurenceb> looks like openssl has no concept of timeouts :(
2022-01-10T21:33:17 < mawk> it's not ssl that's keeping the connection open
2022-01-10T21:33:20 < Laurenceb> I may try signals, but this could get nasty
2022-01-10T21:33:24 < mawk> it's the fact the connection is not finished

2022-01-10T21:33:46 < Laurenceb> it can be held open inside openssl

2022-01-10T22:21:49 < zyp> IIRC this is pretty much as good as it gets: https://github.com/nucleisys/Bumblebee_Core_Doc
2022-01-10T22:23:10 < zyp> I was also getting confused by some documentation of a newer revision of the bumblebee core that documented peripherals and features the one in the gd32v lacks
2022-01-10T22:27:28 <@karlp> thanks, that's useful complaints, but it's not what I'd call "flaky" I guess .)
2022-01-10T22:28:07 < zyp> nah, I don't see any reason to call it flaky

2022-01-10T22:29:11 <@karlp> yeah, it was ventyls word choice, and made me particularly curious
2022-01-10T22:30:41 < zyp> it's probably a perfectly good microcontroller, but I don't really see myself using it in a project, probably mostly because it's cloning gpiov1 :)

2022-01-10T23:14:01 < zyp> looking at https://www.cl.cam.ac.uk/teaching/1617/ECAD+Arch/files/docs/RISCVGreenCardv8-20151013.pdf, rva includes both lr/sc that looks equivalent to ldrex/strex, but also swap and a bunch of other operations
2022-01-10T23:14:46 < zyp> https://msyksphinz-self.github.io/riscv-isadoc/html/rva.html
2022-01-10T23:21:17 < fenugrec> interesting. not sure how a test_and_set would be implemented with those. Not that need to anyway, just interesting
2022-01-10T23:21:24 < fenugrec> that *I need
2022-01-10T23:23:12 < zyp> with which?
2022-01-10T23:24:52 < zyp> ldrex/strex pattern is typically: load value with ldrex, do whatever tests you want, modify value, write modified value back with strex, check if strex succeeded, otherwise retry or abort

2022-01-10T23:53:45  * Laurenceb is getting confused by openssl
2022-01-10T23:54:19 < Laurenceb> it has a session cache, is that "global" i.e. shared across all openssl sessions started by a single user or something?
2022-01-10T23:54:47 < Laurenceb> there is guidance about how to make it thread safe which is confusing me
2022-01-10T23:58:27 < Laurenceb> hmm looks like there is one cache per ctx, I think I see now

2022-01-11T13:20:51 < catphish> so it turns out this design doesn't work - https://i.imgur.com/JwN6hyv.png - because the reverse voltage of the zener is about 1v when R11 is at 6v
2022-01-11T13:21:04 < catphish> need to rethink the 3v3 clamping
2022-01-11T13:22:01 < catphish> this zener at least, chosen without care, requires 5mA to reach 3.3v
2022-01-11T13:29:22 < catphish> i suspect a transistor based level changer is going to be a better choice here
2022-01-11T13:34:23 < BrainDamage> throw another npn and you should be set
2022-01-11T13:34:36 < BrainDamage> bonus points less stuff in the bom
2022-01-11T13:35:55 < BrainDamage> ah no wait, i'm dumb, npn is not a good idea
2022-01-11T13:36:15 < catphish> something about reverse current into emitter
2022-01-11T13:36:37 < BrainDamage> no, base- collector diode would be positively biased
2022-01-11T13:37:38 < BrainDamage> and you'd risk the spikes to flow there
2022-01-11T13:37:46 < catphish> sorry, i man current from base to collector
2022-01-11T13:37:56 < BrainDamage> in theory the c-e channel should be always on when that happens
2022-01-11T13:38:14 < catphish> though perhaps i'm misunderstanding BJT
2022-01-11T13:38:35 < BrainDamage> which whould throw them to gnd
2022-01-11T13:38:58 < BrainDamage> however, depending on the internal resistance, there might be some residuals
2022-01-11T13:39:00 < catphish> that's true
2022-01-11T13:40:55 < catphish> so is this safe? https://i.imgur.com/9IIjNwJ.png
2022-01-11T13:41:22 < BrainDamage> you don't need R11
2022-01-11T13:41:42 < catphish> i do need R11, that has nothing to do with Q?
2022-01-11T13:42:15 < BrainDamage> current flows from D5 to R12 to BE to gnd
2022-01-11T13:42:28 < BrainDamage> why do you need R11?
2022-01-11T13:42:40 < catphish> oh, you're right, sorry
2022-01-11T13:42:52 < catphish> i can just change the value of R12
2022-01-11T13:42:56 < BrainDamage> yup
2022-01-11T13:43:27 < catphish> how much do i owe you :)
2022-01-11T13:43:40 < BrainDamage> and the BE junction will throw that point to gnd when unpowered
2022-01-11T13:43:54 < BrainDamage> so no weird floaty shit
2022-01-11T13:45:07 < catphish> yeah, previously, when unpowered, current flowed into the MCU enough to make Q3 float high, that was annoying
2022-01-11T13:46:38 < catphish> ie MCU_CP went high, MCU_SW went high, current flowed though R9 and Q3, which is actually quite a dangerous state as Q3 enables a high voltage supply, it might be worth pulling R9 down a bit just in case
2022-01-11T13:48:47 < ventYl> that stuff should probably be double-switched using two different switching techniques
2022-01-11T13:49:37 < catphish> that's elegant AF if it works :) https://i.imgur.com/rwkGzeM.png
2022-01-11T15:15:43 < fenugrec> catphish, explain again why R in series with a zener doesn't work ?
2022-01-11T15:16:16 < fenugrec> oh is that some kind of a half-duplex, 12v signal
2022-01-11T15:18:47 < catphish> fenugrec: yes it's a half duplex 12v signal, the end i'm designing needs to be able to detect the difference between +12v and -12v, and needs to be able to pull +12v down with either a 2k7 resistor, or 2k7 + 1k5
2022-01-11T15:19:17 < fenugrec> so there's.... 3 possible levels ? +12, -12, an ~ 0 when mcu pullsdown
2022-01-11T15:19:43 < catphish> no
2022-01-11T15:20:24 < catphish> i'll start from the beginning, coming into my circuit, through D5, there are 3 possible levels, 0v (open), when nothing is connected to it, +12v, or -12v
2022-01-11T15:21:17 < catphish> because of D5, the -12v state is never seen, so in effect, my circuit receives either +12v or 0V at the output of D5
2022-01-11T15:21:32 < catphish> i need to be able to detect that digital level at the MCU
2022-01-11T15:21:48 < catphish> that part is simple enough, but...
2022-01-11T15:22:11 < fenugrec> so you map {hi-Z, +12, -12} to logic {0, 1, 0} ?
2022-01-11T15:22:22 < catphish> fenugrec: correct
2022-01-11T15:22:44 < catphish> that incoming voltage has an impedance of 1k at its source
2022-01-11T15:22:57 < fenugrec> always 1k ?
2022-01-11T15:23:00 < catphish> yes
2022-01-11T15:23:08 < catphish> in order to communicate back the other way, there are 3 possible states
2022-01-11T15:23:30 < catphish> 1) disconnected, i don't care about this, infinite resistance between the signal line and GND
2022-01-11T15:24:06 < catphish> 2) connected, i must hardwire 2k7 between signal and ground, this pulls +12v down to +9v when my device is connected
2022-01-11T15:24:43 < catphish> 3) active, i can switch an additional 1k5 between the signal and ground, this pulls +12v down to +6v when my MCU wants to indicate something to the other end
2022-01-11T15:25:30 < catphish> so this circuit needs to map {hi-Z, -12, +12, +9, +6} to {0,0,1,1,1}
2022-01-11T15:25:43 < catphish> as well as insert the permanent and switched resistors
2022-01-11T15:26:14 < fenugrec> why do you care about the states you drive, just for validation?
2022-01-11T15:26:53 < catphish> sorry, i mis-spoke, i care about those states because this protocol is *full duplex*
2022-01-11T15:27:10 < catphish> when i'm driving +6v, i still care about the difference between +6v and -12v
2022-01-11T15:27:33 < fenugrec> what a horrible 'protocol'
2022-01-11T15:27:40 < catphish> here's the complete circuit https://en.wikipedia.org/wiki/SAE_J1772#/media/File:J1772_signaling_circuit.svg
2022-01-11T15:29:19 < catphish> basically the important part is differentiating +v (>5v) vs 0v without drawing much current
2022-01-11T15:30:17 < catphish> the resistor and zener didn't work because at low current, the zener doesn't reach 3v3, and at high current, it pulls down the rest of the curcuit
2022-01-11T15:30:37 < fenugrec> i see
2022-01-11T15:31:07 < catphish> i believe this ticks all the boxes now though https://i.imgur.com/rwkGzeM.png
2022-01-11T15:31:16 < fenugrec> well, throw it in spice, and check. I would've gone with 2n7002 or garbage mosfets maybe instead of bjt
2022-01-11T15:31:23 < catphish> where MCU_CP has a pull-up in the MCU
2022-01-11T15:32:15 < catphish> either probably works, the benefit of the BJT is that that a mosfet has no way to discharge when D5 is negatively biased
2022-01-11T15:32:27 < fenugrec> if at +5v Q6 shouldn't conduct,  you might need to add a R from base to gnd
2022-01-11T15:33:15 < fenugrec> you could also probably throw in a sot23-5 comparator in there for 0 cost , unless you're building tons of these
2022-01-11T15:33:22 < catphish> fenugrec: no, that's fine, absolutely any time D5 is positively biased, logic 1 is ok, 5v is just the minimum i MUST detect
2022-01-11T15:33:24 < fenugrec> not sure if it'd help though.
2022-01-11T15:34:51 < fenugrec> catphish, I think you'll find  Q6 will turn off very slowly when input goes from + to -, unless you turn on Q3 to help
2022-01-11T15:35:00 < fenugrec> may/may not be a problem
2022-01-11T15:35:31 < catphish> that is a big problem
2022-01-11T15:35:37 < catphish> but why?
2022-01-11T15:35:46 < fenugrec> holy crap -29C outside this morning
2022-01-11T15:35:52 < catphish> nice, where?
2022-01-11T15:36:04 < fenugrec> .qc.ca
2022-01-11T15:36:30 < catphish> cool, i've been trying to work out where cold to visit next winter
2022-01-11T15:37:14 < fenugrec> land anywhere in canadia in mid-late january, drive north a few hours, and you'll be set
2022-01-11T15:37:28 < fenugrec> except maybe toronto
2022-01-11T15:38:35 < fenugrec> Also you might need a diode from q6_base to your vcc_io, this being automotive, you probably need to plan for +30v transients or something
2022-01-11T15:39:16 < ventYl> catphish: this is the line over which the XML-based procotol is transferred?
2022-01-11T15:40:02 < catphish> ventYl: it would be, physically, if i was using that protocol, but no, i'm using the much simpler protocol
2022-01-11T15:40:12 < catphish> which is nothing but PWM
2022-01-11T15:40:18 < fenugrec> what's the bitrate/freq
2022-01-11T15:40:31 < ventYl> catphish: damn, that interface is nasty
2022-01-11T15:40:33 < catphish> it's 1kHz PWM
2022-01-11T15:41:27 < catphish> the duty cycle should to be measured to an accuracy of 10us ideally
2022-01-11T15:42:39 < fenugrec> I'd really consider a comparator in that case, to give you nice clean edges
2022-01-11T15:43:17 < catphish> why wouldn't a BJT fall fast?
2022-01-11T15:44:40 < fenugrec> it won't be a sharp turnoff, but at 1khz maybe that doesn't matter. can't explain the exact mechanism... I don't think it's only because of capacitance in the device
2022-01-11T15:44:43 < catphish> this is basically the exact reason i didn't use a mosfet, i figured a BJT would discharge instantly to its emitter
2022-01-11T15:45:19 < fenugrec> for some definitions of "instantly", maybe. I want to say a few 5-10us of delay maybe ?
2022-01-11T15:45:23 < fenugrec> spice ftw
2022-01-11T15:45:29 < catphish> yeah, would be nice to simulate
2022-01-11T15:45:30 < BrainDamage> it is capacitance of the device, miller effect of capacitor of base-collector
2022-01-11T15:45:31 < fenugrec> or build it
2022-01-11T15:45:43 < BrainDamage> the capacitance gets multiplied by the gain of the device
2022-01-11T15:46:18 < catphish> i used to like evectronics
2022-01-11T15:46:23 < catphish> *electronics
2022-01-11T15:46:38 < BrainDamage> but we're talking about pF gets turned into say, nF
2022-01-11T15:46:40 < fenugrec> evictronics, is when you kick everything outside
2022-01-11T15:46:50 < catphish> lol
2022-01-11T15:46:57 < BrainDamage> so even with a mA current, you'll easily get us switching time
2022-01-11T15:48:09 < catphish> base current should be 4.4mA
2022-01-11T15:48:51 < BrainDamage> yeah, no issue with switching time
2022-01-11T15:49:33 < fenugrec> BrainDamage, I would assume those characteristics would change a lot vs junction temperature (gain especially)... c'mon catphish , an lmv331 is like 0.50$
2022-01-11T15:50:11 < catphish> does lmv331 solve my actual level shifting problem?
2022-01-11T15:50:58 < fenugrec> not completely, but mostly : set threshold to +5v, protect the input, keep your pull-down bjt/mosfet, and done
2022-01-11T15:51:31 < catphish> oh, you mean use it to create a push pull to drive a mosfet?
2022-01-11T15:52:04 < fenugrec> ? no, comparator drives your logic side, to give you 0/3.3v or whatever
2022-01-11T15:52:34 < catphish> can a comparator take a 12v input and give a 3v3 output?
2022-01-11T15:53:11 < catphish> because i assumed not
2022-01-11T15:53:35 < BrainDamage> they are normally open collector, your problem is that your supply rail is also one input
2022-01-11T15:54:24 < BrainDamage> so it's becoming a complex circuit that's equivalent to a transistor
2022-01-11T15:54:34 < catphish> lol
2022-01-11T15:54:53 < catphish> if the BJT capacitance isn't a problem, i'll use it, but it's worth simulating / testing
2022-01-11T15:55:06 < fenugrec> didn't claim it was simpler, but if you want to detect a transition at +5v "within 10us" accurately, a bjt is going to be disappointing IMO
2022-01-11T15:55:53 < catphish> i'll have to learn some spice
2022-01-11T15:55:58 < BrainDamage> the main adv of the comparator is that it smaller sizes, so less capacitance
2022-01-11T15:56:31 < BrainDamage> but otherwise, it'll still be limited in slew rate by the last stage's current driving the miller's cap
2022-01-11T15:57:59 < fenugrec> a while back I was simulating this - half-duplex K line (simpler, just +12/0V), but with some hysteresis https://ibb.co/VqnTQmX
2022-01-11T15:58:12 < fenugrec> sim'ed it, built it, never tested it
2022-01-11T16:00:21 < catphish> on an unrelated note, why are almost all electronics lectures on youtube delivered in english with strong indian accent?
2022-01-11T16:00:37 < catphish> does india have a big online learning culture?
2022-01-11T16:00:49 < ventYl> :D
2022-01-11T16:01:09 < catphish> like this guy https://www.youtube.com/watch?v=8ud2lcSsuRQ
2022-01-11T16:07:17 < catphish> i feel like i should consider this design too https://i.imgur.com/W0TvRgk.png
2022-01-11T16:07:54 < fenugrec> if input can be > Vgs_max of you rmosfet (usually ~ 20V), you'll need moar protection
2022-01-11T16:08:28 < catphish> it shouldn't be, a tvs might be a good idea though
2022-01-11T16:09:07 < catphish> i'll look into the timing implications of the BJT setup anyway, because i like that one
2022-01-11T16:11:11 < BrainDamage> miller effect is present in mosfet too
2022-01-11T16:11:30 < BrainDamage> anytime you have a capacitor across an inverting amp you have it
2022-01-11T16:11:48 < BrainDamage> the gate charge of mosfets includes that effect
2022-01-11T16:21:39 < catphish> i don't think there's a question some solderless breadboard can't answer :D

2022-01-11T18:19:33 < catphish> IMO this will not be significant in my application
2022-01-11T18:21:26 < catphish> it looks like it's approximately 10uS between the start of the falling input slope, and the output slope passing the 1.8v threshold, i don't love it, but i'm also not inclined to worry about it
2022-01-11T18:21:45 <@karlp> "A Notecard purchase includes 500 MB of data that is usable over 10 years "
2022-01-11T18:21:53 <@karlp> well, great! lots of data then!
2022-01-11T18:22:14 < BrainDamage> catphish: if that's on a breadboard, it's going to be way fastah on a pcb
2022-01-11T18:22:36 < BrainDamage> because the breadboard capacitance dominates over the transistor's parasitics
2022-01-11T18:22:47 < catphish> that's on a breadboard with whatever BJTs i had lying around (BC301)
2022-01-11T18:23:10 < BrainDamage> so you won't even see the rise with a 10 us scale
2022-01-11T18:23:24 < catphish> i also suddenly wondered if the input diode is redundant now
2022-01-11T18:23:58 < BrainDamage> what's it for?
2022-01-11T18:24:04 < BrainDamage> reverse protection?

2022-01-11T18:24:45 < catphish> D5 here https://i.imgur.com/rwkGzeM.png - its purpose is to prevent R10 and R11 conducting anything when EVSE_CP is < 0v
2022-01-11T18:26:16 < catphish> i think it is needed, to prevent current from MCU_SW flowing back to EVSE_CP
2022-01-11T18:26:57 < catphish> the real reason for it is so that the other device can reliably determine the difference between a car and a puddle of water
2022-01-11T18:28:35 < BrainDamage> Vbe breakdown is on the order of 5V or so
2022-01-11T18:29:00 < BrainDamage> so if for some reason input goes very negative, the bases will go poof
2022-01-11T18:29:31 < catphish> i'll leave it in then to keep everything happy
2022-01-11T18:30:09 < catphish> if that turn off delay is consistent and present in the final PCB, i can always compensate in software
2022-01-11T18:30:11 < BrainDamage> you can remove if the dirty spikes won't get in when the line is unpowered
2022-01-11T18:30:30 < BrainDamage> because the dc bias will prevent it going negative
2022-01-11T18:30:53 < BrainDamage> if instead they are present when there's no dc bias, then they can go negative and pop the bjt
2022-01-11T18:30:58 < catphish> what's to stop current flowing from MCU_SW to EVSE_CP if i remove it?
2022-01-11T18:31:54 < BrainDamage> mmm, nothing, but that's going to be a tiny current
2022-01-11T18:32:17 < catphish> oh, i guess it will be tiby because it's shorted to GND
2022-01-11T18:32:22 < catphish> *tiny
2022-01-11T18:32:31 < catphish> i'll test that
2022-01-11T18:33:57 < BrainDamage> if  EVSE_CP is at gnd, it'll be a (Vdd-0.7)/4.2k current
2022-01-11T18:34:05 < BrainDamage> into a very low impedance
2022-01-11T18:34:18 < BrainDamage> which shouldn't rise any voltage

2022-01-11T18:42:57 < catphish> oh, being shorted to GND is irrelivent because GND is well above -12V
2022-01-11T18:43:06 < catphish> the diode is definitely necessary
2022-01-11T18:43:13 < fenugrec> catphish, I was close with my "5-10us delay" guestimate then P)
2022-01-11T18:43:29 < BrainDamage> if it goes to -12 the diode is necessary, yes
2022-01-11T18:43:30 < catphish> fenugrec: looks like it!
2022-01-11T18:43:52 < catphish> BrainDamage: yep, seems obvious now
2022-01-11T18:44:15 < catphish> this poor EVSE has probably never seen to many fault conditions in its life :)
2022-01-11T18:46:05 < mawk> did you read art of electronics catphish ?
2022-01-11T18:46:11 < mawk> is it a good book by your standards BrainDamage ?
2022-01-11T18:46:50 < catphish> mawk: i don't think i did, though i do still have a copy sat somewhere
2022-01-11T18:46:50 < BrainDamage> I've only skimmed it, I saw it had nothing new for me and then didn't give a 2nd thought
2022-01-11T18:47:19 < catphish> so, the whole setup, with the diode, resistors, and 2 BJTs works flawlessly
2022-01-11T18:47:51 < mawk> I read the analog electronics part, it was pretty understandable with a minimum of maths background; you should try it catphish you said you used to like electronics, you will like it again
2022-01-11T18:51:07 < catphish> so i'm happy, i get a nice reliable 3v3 into my MCU with the 1khz PWM, regardless of the state of the rest of the circuit, and the rest of the circuit is pulled down to 9v or 6v as it's supposed to be, the EVSE is happy and gives me 240VAC when it's asked :)
2022-01-11T18:51:20 < catphish> now i just need to write the code to measure the PWM periods

2022-01-11T20:36:49 < BrainDamage> also, you said diodes, does that mean you're going for non-syncronous rectification in the buck?
2022-01-11T20:37:23 < BrainDamage> because 500A*0.3V 0 = molten silicon
2022-01-11T20:37:25 < Laurenceb> yeah, the input is DC
2022-01-11T20:37:41 < Laurenceb> then a buck convertor down to 800V DC
2022-01-11T20:38:11 < BrainDamage> the buck still has a diode, which can be replaced with a mos/igbt for syncronous operation
2022-01-11T20:38:24 < BrainDamage> and if you have 2MW flowing, you should have ...
2022-01-11T20:39:57 < Laurenceb> hmm interesting idea, but diode should be ok
2022-01-11T20:40:26 < BrainDamage> it's super standard ...
2022-01-11T20:41:00 < Laurenceb> it could fail horribly...

2022-01-11T21:59:52 <@karlp> wow, metal can transistors? where'dyou get that stash catphish?!
2022-01-11T22:00:02 <@karlp> you don't look old enouh in your pictures for that sort of shit
2022-01-11T22:03:13 < jpa-> karlp: yeah, and inspired by that i uploaded kicad file :D
2022-01-11T22:03:51 <@karlp> I don't feel they did a good job of telling what would be improved honestly.
2022-01-11T22:04:12 <@karlp> gettingnet names ona test report isn't really a selling point.
2022-01-11T22:05:24 < catphish> karlp: i have no idea, they were in my drawer, probably some generic stuff i got from ebay to fill my drawer years ago
2022-01-11T22:06:16 < catphish> what to modern BJTs look like? TO-220?
2022-01-11T22:07:07 <@karlp> depending on power, but to-92 for "basic" stuff people breadboard with, and yeah, to220 for bigger ones.
2022-01-11T22:07:22 <@karlp> they're often "the same" depending on what you bought, but metal cans aren't seen much :)
2022-01-11T22:07:33 < catphish> oh yeah, to-92, i've never worked with small through hole stuff really
2022-01-11T22:07:35 < ventYl> are there any modern BJTs? the most-modern switching BJT i've seen is something from TIP-xxx range
2022-01-11T22:07:51  * karlp only remembers TIPxxx as being darlingtons
2022-01-11T22:11:03 < fenugrec> not all TIP are darlingtons; tip29, tip41, etc
2022-01-11T22:11:21 < fenugrec> "modern bjt" - you mean available today, or fresh design ? not sure they're inventing new ones
2022-01-11T22:11:45 < fenugrec> but you'll be able to get a 3904 or 2222 in 50 years probably
2022-01-11T22:13:40 < fenugrec> hahaha wow didn't know there was an Excel demoscene. "why not", i guess..
2022-01-11T22:14:02 < mawk> of course
2022-01-11T22:14:03 < mawk> ex
2022-01-11T22:14:06 < mawk> excel is all powerful
2022-01-11T22:14:25 < mawk> my boss uses excel to do everything, from parsing json to generating bitmap fonts
2022-01-11T22:14:49 < mawk> all handcooked in VBS
2022-01-11T22:16:15 < fenugrec> you can see they're flipping between two sheets probably for More FPS
2022-01-11T22:16:35 < fenugrec> excel double-buffering... never thought that would be a thing
2022-01-11T22:17:29 < ventYl> whole automotive uses excel as primary tool for everything
2022-01-11T22:17:36 < fenugrec> Does anybody recognize the type of connector that would mate with this ? https://ibb.co/RcBWVJD it's smaller than all the obvious (mini-din, mini-xlr, etc); a bit tighter pitch than DB9 for example
2022-01-11T22:18:31 < catphish> karlp: it's peraps useful to have the cheapest, oldest worst parts for prototyping, means whatever chinese surface mount part i choose for the next prototype will be better :)
2022-01-11T22:18:53 <@karlp> modern china is probably actually still bothering to make advances :)
2022-01-11T22:19:23 <@karlp> fenugrec: looks like oneo f the sea of "custom" christmas light chain connectors
2022-01-11T22:19:43 <@karlp> though panel mount, so... less likely?
2022-01-11T22:19:57 < catphish> modern china is setting the way really, for example, UK is adopting their single party political system :)
2022-01-11T22:20:06 < fenugrec> karlp, hm, hadn't thought of that. This is a "probe power" connector on a lot of HP gear but also other mfg's which leads me to believe it may not be 100% custom for HP
2022-01-11T22:21:43 < ventYl> karlp: yeah, most of them, they are basically the most powerful BJT-ish stuff you can buy to replace in legacy design
2022-01-11T22:22:31 < ventYl> then there are some Bosch darlingtons designed as drop-in replacements for vintage automotive stuff

2022-01-11T23:50:04 < Steffanx-> And yours kakium69 .
2022-01-11T23:50:41  * Laurenceb is realising every part of a 2MW inverter is hard
2022-01-11T23:50:51 < Laurenceb> IGBTs and diodes are the easy part
2022-01-11T23:50:59 < Laurenceb> Capacitors and inductor are hard
2022-01-11T23:51:03 < kakium69> Steffanx: I removed that christmas tree thing today
2022-01-11T23:51:23 < Steffanx-> Set it on fire?
2022-01-11T23:51:52 < kakium69> I disassembled it and folded branches in and threw it in a box
2022-01-11T23:52:25 < kakium69> Laurenceb: EV inverters have pretty beefy coils and caps inside
2022-01-11T23:53:23 < kakium69> I have never looked up how those are even connected in circuit
2022-01-11T23:54:15 < kakium69> should look that up
2022-01-11T23:55:32 < kakium69> biggest capacity must ofc be for DC bus rails
2022-01-11T23:56:42 < kakium69> all other L and C are for EMI filtering right?
2022-01-11T23:58:23 < kakium69> wait didn't you have plug and play inverter Laurenceb?
2022-01-11T23:59:02 < BrainDamage> Laurenceb: wait until you figure out that even the traces are hard
2022-01-11T23:59:26 < kakium69> in inverter?
2022-01-11T23:59:29 < BrainDamage> stray inductance and capacitance will store enough energy not just to blow up components, but even kill you

2022-01-12T00:06:54 < kakium69> how do you even become qualified to design 2MW inverter
2022-01-12T00:07:10 < kakium69> 4kV
2022-01-12T00:07:28 < kakium69> maybe just trial and errror
2022-01-12T00:08:13 < kakium69> just go behind protective screen before energizing the inverter

2022-01-12T00:12:30 < kakium69> how do you get power across isolation for 4kv power stage
2022-01-12T00:16:04 < qyx> you just design and if it doesn't kill you, you are probably pretty good and certified

2022-01-12T01:54:29 < kakium69> I think one of ethernet lines caused router to become unstable
2022-01-12T01:54:37 < kakium69> will see
2022-01-12T02:15:02 < catphish> i'm trying to use this setup to clamp 12v digital inputs to 3.3v MCU inputs, i'm quite sure this will work, but i'm worried that it will be much too sensitive to noise then the 12v input is supposed to be low https://i.imgur.com/ka8Q0SW.png - is that the case, and is there an obvious way to make it less sensitive?
2022-01-12T02:15:42 < fenugrec> catphish, did you simulate it !
2022-01-12T02:16:19 < catphish> i'm not sure exactly what i need to simulate
2022-01-12T02:16:40 < fenugrec> you would see how many volts it takes on the input to register a low level on the output
2022-01-12T02:16:52 < fenugrec> *high
2022-01-12T02:16:56 < catphish> it appears that the BJT has a voltage threshold, so it provides some immunity in that way
2022-01-12T02:16:57 < fenugrec> oh its a different circuit
2022-01-12T02:17:11 < fenugrec> yea like 0.6-0.7V
2022-01-12T02:17:12 < catphish> yes, completely different, much simpler concept here
2022-01-12T02:17:38 < fenugrec> are you that limited by # parts / board space / budget ?
2022-01-12T02:17:53 < catphish> 0.65v
2022-01-12T02:18:17 < catphish> fenugrec: not really, i'm just trying to keep it as simple as possible
2022-01-12T02:18:40 < fenugrec> if it's going to be in a vehicle, I'd invest in making it as robust as possible
2022-01-12T02:21:55 < catphish> this may also be an option, lots of zener current - https://i.imgur.com/yKPChIC.png
2022-01-12T02:22:23 < catphish> it would be useful if i knew how to properly simulate these devices
2022-01-12T02:23:49 < fenugrec> dude, I think you've spent enough time on that that learning to simulate would be a good investment
2022-01-12T02:24:26 < catphish> i suspect you're correct
2022-01-12T02:24:55 < catphish> what's the obvious linux spice gui toy?
2022-01-12T02:24:57 < fenugrec> it's not like it's something you'll use just this one time...
2022-01-12T02:25:58 < catphish> looks like kicad might be able to do it, i'll have a play
2022-01-12T02:26:17 < fenugrec> I started with ltspice 3/4 when I was still on Win* but it runs fine under wine. It has weird keybindings, limited library, and some quirks, but works fine. I never tried kicad+ngspice integration, it looks weird(er)
2022-01-12T02:29:05 < fenugrec> look, I can even pretend to be "designing stuff" with it https://ibb.co/NWXH3mm
2022-01-12T02:29:52 < kakium69> catphish: you didn't do divider?
2022-01-12T02:30:01 < kakium69> + zener
2022-01-12T02:31:44 < catphish> kakium69: i can, the problem is that 3v3 zeners, at least the ones i used last time, aren't actually 3v3 unless you get the current correct
2022-01-12T02:31:59 < kakium69> yes
2022-01-12T02:32:24 < catphish> my previous board has a divider and a 3v3 zener, the output voltage barely reaches 2v
2022-01-12T02:33:21 < catphish> now, this is my fault for not reading the zener datasheet and setting the current accordingly, but having the right current over a wide input voltage range is something i thought i might avoid
2022-01-12T02:33:31 < kakium69> that BJT thing looks rather gainy
2022-01-12T02:34:02 < catphish> kakium69: that was my concern of 10 minutes ago indeed :)
2022-01-12T02:34:18 < catphish> gain is good, sort of, i'm trying to make a digital switch
2022-01-12T02:34:36 < catphish> but what i don't want is to go logic high every time there's a tiny noise
2022-01-12T02:34:43 < kakium69> planning to have external pullup for it?
2022-01-12T02:35:00 < catphish> on the input?
2022-01-12T02:35:02 < kakium69> yes
2022-01-12T02:35:04 < catphish> no
2022-01-12T02:35:33 < catphish> this thing is intended to connect to physical switches on a car power supply, so +12v or floating
2022-01-12T02:35:50 < catphish> and floating, in a car, amplified, just seems like a terrible idea
2022-01-12T02:36:00 < kakium69> mcu input
2022-01-12T02:36:24 < catphish> MCU internal 80k pullup
2022-01-12T02:36:35 < catphish> that part at least works perfectly
2022-01-12T02:37:32 < catphish> but fairly weak
2022-01-12T02:41:18 < kakium69> I bet it's not enough
2022-01-12T02:41:58 < catphish> enough for what?
2022-01-12T02:42:47 < kakium69> current

2022-01-12T02:43:47 < catphish> i'm entirely lost how, the internal pullup is enough to keep the pin at 3v3 when a bjt isn't conducting
2022-01-12T02:43:53 < catphish> *lost now
2022-01-12T02:44:24 < catphish> another mildly insane option: linear regulator
2022-01-12T02:44:40 < kakium69> why not change the zener to original design?
2022-01-12T02:46:58 < kakium69> that 80k pullup is 37microamperes you are controlling with that BJT
2022-01-12T02:47:51 < kakium69> it very very little current
2022-01-12T02:47:53 < catphish> that's certainly going to be sensitive
2022-01-12T02:48:28 < catphish> external pullup seems sane
2022-01-12T02:56:18 < kakium69> yet you still might want divider circuit to base of that BJT
2022-01-12T02:56:52 < kakium69> I looked from google images what others have done
2022-01-12T02:57:04 < kakium69> Divider + C -> Base
2022-01-12T02:57:26 < kakium69> external pullup to collector
2022-01-12T02:58:33 < kakium69> did you get the boards with divider + zener catphish?
2022-01-12T02:59:48 < catphish> yes
2022-01-12T03:00:42 < catphish> and strictly speaking, they work, 10v input is enough to reach 2.0 on the MCU, but i don't like it

2022-01-12T03:01:19 < kakium69> did you test soldering off zener?
2022-01-12T03:01:35 < catphish> i did not
2022-01-12T03:01:36 < kakium69> is it already significant at 2V?
2022-01-12T03:01:53 < kakium69> zener current
2022-01-12T03:02:51 < catphish> i might revisit this
2022-01-12T03:03:27 < catphish> because actually, i only need 2.0 for logic high, and zener current should be absolutely negligable at that level
2022-01-12T03:03:46 < kakium69> zener/tvs datasheets have 2 V-I points
2022-01-12T03:03:51 < catphish> a simple adjustment to the divider values (which were wrong anyway) may be all i need
2022-01-12T03:03:55 < kakium69> breakdown and clamp
2022-01-12T03:04:16 < kakium69> those are just 2 points from V-I graph
2022-01-12T03:04:35 < catphish> the curve on this thing is awful https://datasheet.lcsc.com/lcsc/1811142211_ST-Semtech-ZMM3V3-M_C8056.pdf
2022-01-12T03:04:36 < kakium69> sometimes you might mix those when selecting part
2022-01-12T03:04:58 < kakium69> also some zeners have much lower breakdown current than others
2022-01-12T03:05:08 < catphish> 3.3v at 5mA, 4v at 40mA
2022-01-12T03:06:33 < catphish> i need to fix my resistor divider so that the zener actually gets some current, but i need to be careful it's not too much, or i need a better part
2022-01-12T03:09:02 < kakium69> yes
2022-01-12T03:09:23 < kakium69> easiest fix might be to change lower resistor
2022-01-12T03:09:48 < kakium69> let's see
2022-01-12T03:09:54 < catphish> this was the original design, that i have built https://raw.githubusercontent.com/catphish/ev-charge-controller/master/hardware/charge-controller.pdf
2022-01-12T03:10:30 < catphish> the divider is poor, at 10v it would only give 2.11v, even without the diode
2022-01-12T03:13:35 < kakium69> zener is around 2mA at that voltage
2022-01-12T03:14:50 < catphish> if i change the divider to 5.6k / 2.2k, the zener should be conducting more
2022-01-12T03:17:07 < kakium69> even if you dump the whole lower resistor
2022-01-12T03:17:08 < catphish> or just remove the lower resistor entirely, let the zener do all the work
2022-01-12T03:17:31 < catphish> yeah, in my head, leaving the top 5.6k and the zener only should work just fine
2022-01-12T03:17:46 < kakium69> idk if that does much
2022-01-12T03:17:55 < catphish> 2mA should be enough to keep the zener above 2v
2022-01-12T03:19:01 < kakium69> maybe replace lower with some higher value resistor
2022-01-12T03:19:13 < catphish> worst case, 15v / 5k6 = 2.7mA , zener will protect the MCU and itself just fine
2022-01-12T03:20:10 < catphish> down at 8v, there will only be 1.4mA, it's less clear what votage will result
2022-01-12T03:20:27 < catphish> removing the lower resistor from my board is a trivial way to find out though
2022-01-12T03:21:29 < catphish> looking at this chart though, i don't think the zener was ever my problem, i just suck at resistor dividers
2022-01-12T03:22:33 < catphish> i was paranoid about MCU damage
2022-01-12T03:23:32 < kakium69> it is posibility
2022-01-12T03:23:57 < catphish> i'll remove the lower resistor and test first, that is easy and definitive
2022-01-12T03:25:39 < kakium69> hmm interesting
2022-01-12T03:26:13 < kakium69> has input high minimum always been 0.7VDD
2022-01-12T03:27:21 < catphish> it's 2.0 on the RP2040, officially, about 1.6 works on my test board, i don't know about other devices
2022-01-12T03:27:53 < kakium69> 0.7VDD is like 2.3volts
2022-01-12T03:28:33 < kakium69> I don't know if I have ever really paid attention to that
2022-01-12T03:29:17 < kakium69> I have thought something around 1.6 - 1.8volts would be minimum
2022-01-12T03:33:23 < catphish> that was my observation, but obviously i want to meet the specified 2.0 for my MCU
2022-01-12T03:39:32 < kakium69> you could test which lower resistor still gives you 2.0
2022-01-12T03:39:55 < kakium69> then you wouldn't lose pulldown and leave signal floating
2022-01-12T03:40:59 < catphish> *nod*
2022-01-12T03:48:18 < catphish> i'll start with this as a concept, i can test everything there using the existing PCB
2022-01-12T03:48:20 < catphish> https://i.imgur.com/Fq7TlAk.png
2022-01-12T03:49:57 < catphish> i spent a couple of hours earlier testing this on the bench, works well - https://i.imgur.com/OU6gJJm.png
2022-01-12T03:50:19 < catphish> (for the more complicated half of this board)
2022-01-12T03:50:42 < catphish> except it's not that complicated now :)

2022-01-12T11:25:36 < catphish> BrainDamage: the problem is that the zener sinks a little current at a lower voltage than its nominal voltage, and the large value voltage dividers in my previous design don't let enough current through, so the zener drags the voltage down
2022-01-12T11:27:19 < BrainDamage> why do you even have the divider?
2022-01-12T11:28:12 < catphish> i need to turn 12v into 3.3v, that's pretty much it
2022-01-12T11:28:26 < catphish> the lower half of the divider is likely not needed at all
2022-01-12T11:33:21 < BrainDamage> https://i.imgur.com/a6hzCSz.png
2022-01-12T11:33:23 < catphish> ie make the divider with one resistor and a zener, pulldown can happen on the 12v input side if needed
2022-01-12T11:33:50 < BrainDamage> buffered zener
2022-01-12T11:34:22 < BrainDamage> this way it'll be much more tolerant to voltage swings
2022-01-12T11:34:51 < catphish> what i plan to to right now is the left part of that only
2022-01-12T11:34:51 < BrainDamage> can make it even more tolerant by adding another transistor to R1 and turning it to a constant current source
2022-01-12T11:35:07 < catphish> and trusting that the right half is inside the MCU

2022-01-12T11:39:55 < catphish> R3 is just a pulldown and c1 is just a filter, as long as the value of R1 is correct, this should do the job just fine
2022-01-12T11:40:30 < catphish> i can test easily by removing the bottom resistor my my previous design, which just a stupidly small resistor in parallel with the zener

2022-01-12T12:24:00 < Xogium> woohoo I did my first breadboarding ever ;) ok I know nothing to be excited about but it was fun
2022-01-12T12:24:18 < Xogium> hooked up a IR receiver to my stm32mp1 based board
2022-01-12T12:26:50 < mawk> nice Xogium 
2022-01-12T12:26:58 < ventYl> breadboards are IMO even more exciting than standard circuits. given the fact that it is just a bunch of parts sticked into regular board
2022-01-12T12:27:07 < Xogium> hehe
2022-01-12T12:27:08 < mawk> ah yes Xogium I need to find you soldering supply and 2.54mm headers on amazon.fr was that it?
2022-01-12T12:27:21 < Xogium> yeah
2022-01-12T12:32:24 < ventYl> like when I put together USB device out of attiny. hey! it's just a bunch of resistors and zeners around 20 years old MCU, it can't communicate using USB!
2022-01-12T12:33:04 <@karlp> heh, yeah, I built a vusb attiny thing for an ir receiver years ago :)
2022-01-12T12:33:06 <@karlp> felt like magic
2022-01-12T12:33:50 < ventYl> usbasp I still use today is built from scratch using atmega on prototyping board
2022-01-12T12:33:59 < ventYl> but it has crystal, so less magic

2022-01-12T12:43:49 < mawk> plated on both sides is a bit harder to use since the solder tends sinks inside the hole
2022-01-12T12:44:03 < mawk> and just drip down or make an infinitely long solder stalactite

2022-01-12T12:51:07 < PaulFertser> mawk: one side is ok, the idea is to have a layman train a bit on a spare prototype board and then do the same operation on some seeed devboard.
2022-01-12T12:51:19 < PaulFertser> mawk: the devboard has both sides plated of course.
2022-01-12T12:51:42 < PaulFertser> mawk: and some cheap suitable soldering iron.
2022-01-12T12:54:56 < mawk> oh no they don't sell leaded solder anymore on amazon france
2022-01-12T12:58:37 < mawk> ah I found it
2022-01-12T13:00:56 < Laurenceb> it will probably be an array of ~50kW inverters
2022-01-12T13:01:21 < Laurenceb> polyester caps and custom inductors using Litz cable wrapped around a ferrite toroid looks doable
2022-01-12T13:01:43 < Xogium> still sort of baffles me how it is that connecting wires in the holes facing the sensors makes them connected together
2022-01-12T13:02:20 < PaulFertser> Xogium: the holes are metal-plated and have metal PCB traces connected to them.
2022-01-12T13:02:54 < Xogium> oh
2022-01-12T13:03:05 < Xogium> so it can makes electrical connection
2022-01-12T13:11:41 < Xogium> this is strange, one of my 2 breadboards  doesn't work properly… I can't get my wires to stick into it
2022-01-12T13:12:38 < Xogium> my bigger breadboard I definitely hear a click sound when the wire gets all the way through and the plastic attached to it is the only thing you can touch
2022-01-12T13:12:46 < ventYl> sometimes plates inside breadboards are too tight
2022-01-12T13:12:47 < Xogium> but this one, it doesn't even go through
2022-01-12T13:13:40 < Xogium> this bad one seems to get the pin halfway through, then it stops going further, so part of the metal is still showing
2022-01-12T13:15:00 < Xogium> it's also very much smaller than my other breadboard
2022-01-12T13:15:28 < Xogium> small enough that the metal connection under the rows are not covered up
2022-01-12T13:25:23 < steve__> sup dongles
2022-01-12T13:25:56 < Xogium> I'm not a dongle
2022-01-12T13:25:58 < Xogium> ;)
2022-01-12T13:27:05 < steve__> is there a word for like, the equivalent of an adapter plate in mechanics, or an interface in software, but in an electrical schmatic/layout/IC.  like IP block but is there another word?
2022-01-12T13:27:53 < steve__> the word for not the IP block but the interface defined by its external connections
2022-01-12T13:29:18 < steve__> standard is almost there, like a pinout
2022-01-12T13:30:42 < ventYl> simple "electrical interface" might be suitable for some cases, but not all
2022-01-12T13:31:27 < steve__> that made too much sense haha.  that term is used "in the wild" ?
2022-01-12T13:34:39 < PaulFertser> steve__: can you give an example of what can be connected where with such an "adapter plate"?
2022-01-12T13:37:49 < steve__> consider a PCB footprint for a component.  It's a PCB footprint but it's the thing between 2 components
2022-01-12T13:39:10 < steve__> external connections are standardized and very familar.  i mean something on board, or on chip
2022-01-12T13:43:22 < PaulFertser> steve__: there's a footprint and there's a pinout, and there might be different pinouts for the same footprint.
2022-01-12T13:47:52 < Xogium> huh… weird. Just got my ESD mat and it feels like paper or cardboard

2022-01-12T13:59:23 < Laurenceb> you want capacitor?
2022-01-12T13:59:58 <@karlp> 1 in stock
2022-01-12T14:00:38  * karlp is stuck in unknown locale, is that 56.384g or is 56kg?
2022-01-12T14:02:50 < BrainDamage> 50g
2022-01-12T14:03:04 < BrainDamage> that's ~2J
2022-01-12T14:03:28 <@karlp> three sig digits for grams was what was throwin me :)
2022-01-12T14:05:19 < BrainDamage> it's kind of low in terms of energy density
2022-01-12T14:05:44 < BrainDamage> you can get 20kJ for 10-15kg
2022-01-12T14:14:12 < Xogium> well, ok then, looks like my esd mat is made or recycled materials. I guess that's where the papery feeling comes from
2022-01-12T14:14:18 < Xogium> *of
2022-01-12T14:16:32 < BrainDamage> Xogium: remember to tell your friend to use a proper posture when soldering, you can link them https://c8.alamy.com/comp/epf5g9/woman-soldering-epf5g9.jpg
2022-01-12T14:18:26 < Xogium> BrainDamage: ah, thanks
2022-01-12T14:18:44 < Xogium> apparently my mat is made from fiberboard. I guess that explains why it feels like paper
2022-01-12T14:29:10 < mawk> lol BrainDamage 
2022-01-12T14:30:15 < mawk> why is it expensive Laurenceb 
2022-01-12T14:37:33 < ventYl> Laurenceb: why exactly do you need to reinvent wheel? is hyperloop gonna be something extraordinaty in terms of performance compared to other high speed trains?

2022-01-12T14:52:58 < Laurenceb> ventYl: yeah, also we have limited budget
2022-01-12T14:53:47 < ventYl> that's also a great motivation to avoid reinventing wheel
2022-01-12T14:53:58 < Laurenceb> limited as in <$2M that Siemens would charge for appropriate kit
2022-01-12T14:54:25 < Laurenceb> we can probably do it for 100k
2022-01-12T14:55:16 < ventYl> are you working for free? 100k is like 1 month worth of expenses for engineering team working on something like that
2022-01-12T14:56:04 < Laurenceb> lol
2022-01-12T14:56:26 < Laurenceb> I could probably do it in a few months and I dont get paid that much a month
2022-01-12T14:57:32 < ventYl> that's almost always the case, yet there is always corpo or someone else who fucks it up and causes that two-months-long issue disturbs around for three more years

2022-01-12T17:43:37 <@karlp> hrm, was really confusd about st's freertos layer, turns out they use RTC to make a "virtual timers" implementation, and then both use that to implement low power sleep, but _also_ for any sw timers they need in demo apps, instead of using the rtos timers.

2022-01-12T18:16:48 < mawk> do you have fog too Steffanx ?
2022-01-12T18:16:59 < mawk> do you think fog looks good in black and white
2022-01-12T18:17:23 < mawk> last foggy night I took color pictures, it's good because the fog hides the blur lol
2022-01-12T18:17:40 < mawk> but still it didn't render the fog as visible as in real life
2022-01-12T18:18:21 < mawk> you have to know it's fog because otherwise it just looks like unexposed picture
2022-01-12T18:18:27 < ventYl> maybe you need different kind of B&W film
2022-01-12T18:18:48 < ventYl> IIRC there are different kinds of films handling luma differently
2022-01-12T18:20:26 < mawk> hmm
2022-01-12T18:20:31 < mawk> or maybe filters?
2022-01-12T18:20:39 < ventYl> also might work
2022-01-12T18:20:46 < mawk> the film all kinda do more or less the same film
2022-01-12T18:20:52 < BrainDamage> hah, another channel one guy in netherlands was complaining about fog trashing his SNR at 3GHz
2022-01-12T18:20:55 < mawk> expect like orthochromatic film
2022-01-12T18:21:01 < ventYl> i have old soviet lens which has some fancy colored filters
2022-01-12T18:22:05 < BrainDamage> mawk: get a spot light source, like eg a powerful torch
2022-01-12T18:22:13 < BrainDamage> and shine it on the fog
2022-01-12T18:22:29 < BrainDamage> that should give unique effects, and show its nature too
2022-01-12T18:27:30  * Laurenceb is getting confused by flyback convertors
2022-01-12T18:27:43 < Laurenceb> why does everyone say they need a gapped transformer?
2022-01-12T18:27:58 < Laurenceb> surely if the inductance is larger its all good?
2022-01-12T18:28:07 < BrainDamage> because it reduces saturation
2022-01-12T18:28:16 < BrainDamage> look at reluctance circuits
2022-01-12T18:29:26 < Laurenceb> oh ok I kind of understand now
2022-01-12T18:29:46 < Laurenceb> thanks
2022-01-12T18:29:55 < Laurenceb> wondering if I could use an "iso-buck"
2022-01-12T18:31:01 < Laurenceb> https://www.powersystemsdesign.com/blogs/creating-smaller-more-efficient-isolated-power-supplies-with-iso-buck-converters/7
2022-01-12T18:31:02 < BrainDamage> in general fryback are a poor choice for high energy systems
2022-01-12T18:31:08 < Laurenceb> but its "flyback like"
2022-01-12T18:31:09 < Laurenceb> yeah
2022-01-12T18:31:34 < BrainDamage> you want your reactive components to store the least amount of energy possible and flyback do the opposite
2022-01-12T18:32:33 < Laurenceb> yeah
2022-01-12T18:32:46 < BrainDamage> but fryback are simple and easy to control ( esp if you look at the output's characteristic downards slope ), which is why they are diffused
2022-01-12T18:33:43 < BrainDamage> if you go full isolated secondary, consider a h bridge or a center tapped half bridge
2022-01-12T18:34:03 < sauce> bmcc
2022-01-12T18:34:41 < BrainDamage> center tapped half bridge requires just two mos, but requires transformer with centre tap, but since you're winding your own, it's no issue

2022-01-12T18:41:05 < Laurenceb> problem is center tapped requires IGBTs to withstand 2 x input voltage
2022-01-12T18:42:54 < BrainDamage> voltage is less than issue of current, with voltage you either enter breakdown or not, with current you have linear increase of consumption
2022-01-12T18:43:31 < BrainDamage> and I need to remind you that even 1% of 2MW is 20kW
2022-01-12T18:45:11 < Laurenceb> hopefully it doesnt have to be isolated, that isnt clear yet
2022-01-12T18:45:52 < Laurenceb> a buck convertor looks simplest
2022-01-12T18:47:46 < BrainDamage> is there some website for private betting?
2022-01-12T18:48:02 < BrainDamage> since it's not a question if it'll explode, we could bet on when it explode

2022-01-12T20:55:43 < zyp> if it has to be a configurable parameter, I think the most reasonable solution is to make it a template argument that's filled when defining the instance
2022-01-12T20:55:48 < zyp> as in C++ template
2022-01-12T20:56:13 < zyp> that'll avoid the need to generate the file with the register layout itself

2022-01-12T22:50:31 < mawk> lol
2022-01-12T22:51:09 < catphish> if this design doesn't work, i'm officially going on a killing spree https://raw.githubusercontent.com/catphish/ev-charge-controller/v3/hardware/charge-controller.pdf and https://raw.githubusercontent.com/catphish/ti-daisychain-bms/v3/hardware/ti-bms.pdf
2022-01-12T22:59:39 < catphish> i just need to test that 4k7 + zener setup
2022-01-12T23:15:00 < catphish> Laurenceb: how's project "certain explosion" going?
2022-01-12T23:15:11 < Laurenceb> lol
2022-01-12T23:15:31 < Laurenceb> need to reach agreement within team about what the goals are
2022-01-12T23:15:41 < Laurenceb> that could take as long as the project itself...
2022-01-12T23:17:19 < catphish> i often flipflop between "requirements need to be specified properly" and "lets just get on and make something, it can be perfected later"
2022-01-12T23:20:20 <@karlp> zyp: I guess, could just find thebiggest anyone says, but thought it might be nice so youcan get (maybe) some validity checking on what you're doing
2022-01-12T23:29:45 < zyp> sounds nice to have, but not worth spending too much time on :)
2022-01-12T23:49:03 <@karlp> sure, looks like 32 is enough for f7 and g4 and l4 and wb at least, so will just make it 32 then :)
2022-01-12T23:50:00 < catphish> 32 who?

2022-01-13T00:23:28 < Laurenceb> lol guy from my school used to do that shit
2022-01-13T00:23:39 < Laurenceb> he got sent to young offenders
2022-01-13T00:24:02 < kakium69> what shit
2022-01-13T00:24:30 < Laurenceb> stealing cars using script kiddy tools
2022-01-13T00:24:38 < kakium69> how
2022-01-13T00:24:52 < kakium69> how to steal car?
2022-01-13T00:25:42 < Laurenceb> usually smash a side window then connect a can adaptor to the OBD2 port
2022-01-13T00:26:59 < kakium69> then wait half an hour to new key module gets programmed?
2022-01-13T00:27:16 < Laurenceb> something like that
2022-01-13T00:27:44 < kakium69> but there was some BMWs that you could basically walk in and drive away
2022-01-13T00:27:50 < kakium69> if you had some kind of device
2022-01-13T00:29:29 < kakium69> in 90s people used to borrow cars from strangers
2022-01-13T00:30:37 < machinehum> Just don't get caught selling the device
2022-01-13T00:30:45 < machinehum> Don't actually steal the cars
2022-01-13T00:30:48 < machinehum> Just enable crime=
2022-01-13T00:31:07 < kakium69> nowdays it's an industry
2022-01-13T00:31:17 < machinehum> SDR can be very disruptive in the car theft industry
2022-01-13T00:31:36 < machinehum> Do people still steal cars?
2022-01-13T00:31:47 < kakium69> high value cars are picked and taken straight to chop shop
2022-01-13T00:31:52 < machinehum> Don't they get ... caught
2022-01-13T00:31:59 < machinehum> Fair, chop shop
2022-01-13T00:34:23 < kakium69> there is not too many car models you could steal with low-tech approach so "borrowing" is not that common anymore
2022-01-13T00:34:38 < catphish> older cars it was pretty easy to disable immobilizer via OBD2 port, though you had to have the right tool for the right ECU to hand in advance
2022-01-13T00:35:01 < catphish> anything made in the last 10 years, better to just steal the keys
2022-01-13T00:40:24 < machinehum> i see you guys know a lot about stealing cars
2022-01-13T00:41:40 < kakium69> catphish: new cars have write protect set for flash?
2022-01-13T00:44:40 < catphish> kakium69: i had a 2003 VAG i used to hack, it had simple EEPROM config for lots of things, including whether the immobilizer was enabled or not, and a simple protocol to write those settings
2022-01-13T00:44:59 < kakium69> ah
2022-01-13T00:45:07 < kakium69> separate from program mem?
2022-01-13T00:45:17 < catphish> i don't know why it's harder in modern cars, but my assumption would be that they only accept such writes with autentication
2022-01-13T00:45:22 < catphish> kakium69: yes
2022-01-13T00:45:37 < kakium69> I have seen those softwares for "hacking" ecu
2022-01-13T00:45:51 < kakium69> checkboxes like "immobilizer disable"
2022-01-13T00:46:00 < catphish> yeah, that's what i had
2022-01-13T00:47:02 < catphish> i got it because i needed to replace the gauge cluster, an in my car the immobilizer would only work if the VIN in the gauge cluster mateched the VIN in the ECU, god knows why
2022-01-13T00:47:13 -!- System_Error [~SystemErr@user/systemerror] has joined ##stm32
2022-01-13T00:47:41 < catphish> i was able to buy a used cluster, and program the correct VIN and mileage into it with simple hex editing of its EEPROM
2022-01-13T00:48:06 < catphish> the tool i used had featured to modify the ECU eeprom too to disable the immonilizer
2022-01-13T00:48:24 < catphish> but i was happy i was able to do the repair without disabling i
2022-01-13T00:48:26 < catphish> *it
2022-01-13T00:49:11 < catphish> this was all just simple plain text EEPROM though, no crypto, no modifying the program code
2022-01-13T00:49:35 < catphish> that same EEPROM contained things like the fuel / throttle maps, so you could "remap" which was cool
2022-01-13T00:49:54 < kakium69> whaa
2022-01-13T00:49:59 < kakium69> maps are there
2022-01-13T00:50:14 < kakium69> can I program my car to optimize fuel economy?
2022-01-13T00:50:23 < catphish> depends on the car
2022-01-13T00:50:34 < catphish> kind of annoying that the threat of theft has meant that such data is no longer user readable / writeable
2022-01-13T00:51:48 < catphish> the other annoying part, was that none of this was open source / published, i needed about 4 different dodgy programs / cables to modify different things
2022-01-13T00:51:59 < kakium69> ofc
2022-01-13T00:52:47 < catphish> at the time, i was inspired to create an open source framework for vehicle hacking, to which people could add code for specific ECUs
2022-01-13T00:53:30 < catphish> but at that time, new cars were near impossible to hack, so i didn't see that it was goin anywhere
2022-01-13T00:54:52 < ventYl_> catphish: basically, use of `write by address` service is discouraged in new cars
2022-01-13T00:55:18 < ventYl_> and `write by id` required security authentication before tester is allowed to write the data
2022-01-13T00:58:11 < catphish> ventYl_: that makes perfect sense, but it's a real shame
2022-01-13T00:59:31 < ventYl_> weeell, i don't think so
2022-01-13T00:59:31 <@karlp> if you have a weak symbol, can you provide your own implementation that then calls the weak default?
2022-01-13T00:59:37 <@karlp> or do I have to clone the whole thing?
2022-01-13T01:00:01 < ventYl_> karlp: you can wrap that symbol while linking
2022-01-13T01:00:04 < ventYl_> and then call it
2022-01-13T01:00:23 < ventYl_> IIRC, linker has some convenience switch for it (--wrap ?)
2022-01-13T01:00:31 < kakium69> ventYl_: any physical measures against rewriting key?
2022-01-13T01:00:46 < ventYl_> kakium69: rewriting what key?
2022-01-13T01:00:48 -!- Laurenceb [~Laurenceb@82.177.208.46.dyn.plus.net] has quit [Quit: Client closed]
2022-01-13T01:00:56 < kakium69> for authentication
2022-01-13T01:01:48 < ventYl_> kakium69: depends. in older ones, it is probably doable, newer ones have dedicated security peripheral. there you rely on a bug in it's implementation
2022-01-13T01:01:59 < kakium69> oh
2022-01-13T01:03:03 < ventYl_> like in most recent models, you have challende-response authentication mechanism, so you need active connection back to OEM to generate response for you so you can talk to ECU
2022-01-13T01:03:10 < ventYl_> *challenge-response
2022-01-13T01:04:36 < kakium69> how does MB star work?
2022-01-13T01:04:44 < ventYl_> MB star?
2022-01-13T01:04:56 < kakium69> their diagnosis system
2022-01-13T01:05:12 < kakium69> I have heard it needs connection to MB
2022-01-13T01:05:27 < kakium69> but is it just for the software
2022-01-13T01:05:29 < ventYl_> given the schema, it uses challenge-response authentication with dedicated security peripheral
2022-01-13T01:05:43 < ventYl_> well, you have different security levels there
2022-01-13T01:06:07 < ventYl_> some of them may be unlocked by pre-shared key used to generate responses, which are not relying on connection to MB
2022-01-13T01:06:30 < kakium69> how long back does that thing go?
2022-01-13T01:07:01 < kakium69> that MB modules would have challenge-response things
2022-01-13T01:07:22 < kakium69> all way to early 2000s?
2022-01-13T01:07:24 < ventYl_> dunno, i am not familiar with previous architectures, but I'd say that 1-2 generations at most
2022-01-13T01:07:27 < ventYl_> nooooo
2022-01-13T01:07:31 < kakium69> 2004?
2022-01-13T01:07:37 < ventYl_> more like 3-4 years at most I guess
2022-01-13T01:07:56 < ventYl_> it all looked just too flaky to be in use for a long time
2022-01-13T01:08:08 < ventYl_> but maybe it was just due to all the software around
2022-01-13T01:08:47 < kakium69> is there tools for home players for MB?
2022-01-13T01:09:14 < kakium69> like you would need one with MB
2022-01-13T01:09:23 < ventYl_> like, DIY diagnostics?
2022-01-13T01:09:27 < kakium69> ye
2022-01-13T01:09:30 < ventYl_> probably yes
2022-01-13T01:09:43 < ventYl_> due to american "right to repair" act
2022-01-13T01:12:48 < ventYl_> like, most of read operations, except of stuff, which could compromise safety and/or security, are open
2022-01-13T01:13:17 < ventYl_> so you can reach all the diagnostic information you want without having to authorize
2022-01-13T01:20:18 < kakium69> it's so warm
2022-01-13T01:20:22 < kakium69> -1C
2022-01-13T01:20:38 < ventYl_> kakiumland is warmer than we are?
2022-01-13T01:20:47 < ventYl_> we have like -7
2022-01-13T01:21:43 <@karlp> ventYl_: yah, that sounds like way more effort then :)
2022-01-13T01:22:21 < ventYl_> karlp: you can also play with object files, rename symbols, promote them from weak to non-weak and do usual bussiness to call them renamed
2022-01-13T01:22:56 < ventYl_> there's one problem with weak symbols... if they don't get bound while linking, they are thrown away with -gc-sections and -ffunction-sections
2022-01-13T01:23:01 < ventYl_> which pretty much can't be prevented
2022-01-13T01:25:39 <@karlp> yeah, I'm just going to copy the parent, it's not big.
2022-01-13T01:25:57 <@karlp> anyway, it's late. too late for the next steps...
2022-01-13T01:31:19 < catphish> <ventYl_> like, most of read operations, except of stuff, which could compromise safety and/or security, are open << when you say open... is any of this actually documented? or just "not totally blocked"?
2022-01-13T01:31:46 < ventYl_> catphish: depends on how much you wanna pay
2022-01-13T01:32:13 < catphish> i've found a gross lack of open source vehicle management tools, which suggests a lack of documentation
2022-01-13T01:32:47 < catphish> the obvious example is VCDS, all VW protocols are reverse engineered, and yet you still have to pay for the software
2022-01-13T01:32:56 < catphish> this is really weird to me
2022-01-13T01:32:57 < ventYl_>  catphish: problem is twofold. first, land of diagnostic protocols is jungle
2022-01-13T01:33:15 < fenugrec> everybody who does enough RE to do something practical ends up commercializing their stuff, because it was a shitton of work, and because $
2022-01-13T01:33:29 < ventYl_> there is OBD and UDS, but OBD is useless for anything else than emission control and UDS is customized by pretty much everyone who uses it
2022-01-13T01:33:43 < fenugrec> except a few oddball projects, a few of which I'm very familiar with P )
2022-01-13T01:33:48 < ventYl_> moreover, many OEMs use their own proprietary protocols
2022-01-13T01:34:14 < catphish> can't the just, like, publish them?
2022-01-13T01:34:24 < catphish> i'm sure the community will make the tools!
2022-01-13T01:34:25 < ventYl_> second, having the protocol is just half of the job. you need to know IDs, conversion polynomas and/or mapping tables
2022-01-13T01:35:03 < ventYl_> they usually publish them, to companies who are willing to pay :)
2022-01-13T01:35:19 < ventYl_> like, you have Bosch KTS system, which can diagnose pretty much any car imported or made in Europe
2022-01-13T01:35:22 < ventYl_> except of Ford
2022-01-13T01:35:48 < catphish> that's not what i meany publish :)
2022-01-13T01:36:05 < catphish> i like free software!
2022-01-13T01:36:07 < fenugrec>  I released nisprog in ~ 2016 and 90% of users understand barely enough to not brick their ECU, let alone do advanced stuff like find maps and RE stuff
2022-01-13T01:36:42 < fenugrec> so no, "the community" isn't going to do squat, except a few maniacs. MFGs don't give a crap, they don't want you tuning their ECUs. "liability"
2022-01-13T01:36:51 < catphish> my dream is still of a single open source CAN tool that people can add modules to for each vehicle module
2022-01-13T01:37:34 < fenugrec> lol. Well romraider is cool, and works with at least subaru + nissan to some extent, but it's basically a very fancy hex editor with XML and domain-specific magic
2022-01-13T01:37:41 < catphish> but manufacturers need to be helpful
2022-01-13T01:38:00 < fenugrec> why would they
2022-01-13T01:38:20 < catphish> because it's not that hard to publish those docs
2022-01-13T01:38:36 < ventYl_> catphish: well, there's something called product responsibility. manufacturers don't want you to hack street-legal ECUs just like that, because it is mandatory for cars to stay within emission limits for their whole lifetime
2022-01-13T01:38:43 < catphish> lower repair costs, more sales?
2022-01-13T01:38:54 < fenugrec> nobody buys a new car on the basis of how tunable / aftermarket-friendly it is. Better to not invest a single millisecond to publish anything. And as I said, liability. Their lawyers definitely don't want people haxing their cars
2022-01-13T01:39:37 < catphish> it is mandatory for cars to stay within emission limits for their whole lifetime - mandatory for the user, not the manufacturer
2022-01-13T01:39:42 < ventYl_> catphish: well, you do not understand it
2022-01-13T01:39:56 < ventYl_> repairs are part of car's economic lifecycle
2022-01-13T01:40:15 < ventYl_> do you know why replacement ECU costs an arm and a leg?
2022-01-13T01:40:52 < catphish> that's my point, as an example, to diagnose my car, i have to use VCDS, this tool costs money, this adds to the cost when i want to get my car repaired
2022-01-13T01:41:18 < catphish> if this protocol wee published, diagnostic tool would be free, repair would be cheaper, cost of ownership would be less, car would be more attractive
2022-01-13T01:41:28 < ventYl_> UDS is published
2022-01-13T01:41:31 < ventYl_> ISO14227-1
2022-01-13T01:41:38 < ventYl_> or 14229
2022-01-13T01:41:40 < fenugrec> 14229 yea
2022-01-13T01:41:54 < ventYl_> I actually have it implemented in my SW stack
2022-01-13T01:41:58 < ventYl_> mostly compatible
2022-01-13T01:42:12 < fenugrec> nice
2022-01-13T01:42:16 < catphish> i'm not aware of any free tool that can so what VCDS does
2022-01-13T01:42:47 < catphish> in terms of accurate fault code reporting on all modules
2022-01-13T01:42:49 < ventYl_> UDS is not a rocket science
2022-01-13T01:43:04 < ventYl_> you can implement it ~4K
2022-01-13T01:43:09 < catphish> i could be wrong, but i've not come across such a thing
2022-01-13T01:43:12 < fenugrec> catphish, freediag has some VW code (KWP1281) but maybe != VCDS I dunno https://github.com/fenugrec/freediag/blob/master/scantool/diag_l2_vag.c
2022-01-13T01:43:47 < catphish> "freediag" sounds exactly like what i want to exist
2022-01-13T01:44:03 < ventYl_> catphish: well, you refuse to understand, that repair shop network is part of the bussiness. OEMs calculate with incomes from repairs into revenue from selling the car
2022-01-13T01:44:14 < ventYl_> in EU, there's even something called "block exception"
2022-01-13T01:44:49 < ventYl_> if car manufacturer introduces new part or assembly, for several years, nobody else is allowed to introduce 3rd party replacement
2022-01-13T01:45:04 < ventYl_> because, to design a car costs a shitload of money
2022-01-13T01:45:27 < catphish> ventYl_: surely they're "allowed", just not able
2022-01-13T01:45:29 < ventYl_> likely somewhere around $1 bn (10^9)
2022-01-13T01:45:38 < ventYl_> catphish: nope, they are not even allowed
2022-01-13T01:45:57 < catphish> ventYl_: i thought law was pro-compatible-parts
2022-01-13T01:45:58 < ventYl_> that's why it is called "block exception" as it is an exception from free trade policy
2022-01-13T01:46:23 < ventYl_> after that period expires, anyone can import whatever he wants
2022-01-13T01:46:39 < catphish> i don't see what law would stop someone
2022-01-13T01:46:45 < ventYl_> but after new subassembly is introduced, you won't get parts from anyone else than OEM
2022-01-13T01:46:56 < catphish> the limitation is purely technical
2022-01-13T01:47:57 < catphish> fortunately i can't imagine i will be buying a non-open-source vehicle for a while :)
2022-01-13T01:48:33 -!- upgrdman [~upgrdman@47.180.47.55] has joined ##stm32
2022-01-13T01:48:48 < kakium69> and if you do you opensource it first thing
2022-01-13T01:49:08 < catphish> i will also be spending silly money for the privilege of having an open source car :D
2022-01-13T01:50:08 < kakium69> I don't think there is anything open source in automotive industry
2022-01-13T01:50:22 < ventYl_> hm, depend
2022-01-13T01:50:23 < ventYl_> s
2022-01-13T01:50:37 < catphish> openinverter
2022-01-13T01:50:47 < kakium69> is it used in production?
2022-01-13T01:50:57 < catphish> FSVO production
2022-01-13T01:50:59 < ventYl_> AUTOSAR actually is fully open, all specs are freely available, you can get your copy and create your own implementation, data models are basically interoperable
2022-01-13T01:51:13 < ventYl_> but you can't affect AUTOSAR design unless you are part of autosar consortium
2022-01-13T01:51:17 < catphish> increasing numbers of vehicles on the road using it, but not mass production
2022-01-13T01:51:36 < catphish> hardly a dent in the market
2022-01-13T01:51:53 < catphish> but it exists, kit cars, rebuilt classic cars
2022-01-13T01:52:31 < ventYl_> as I see it, the root cause is that pretty much everyone with influence in automotive industry is either incompetent, or straight idiot
2022-01-13T01:52:47 < catphish> in a way, it's just the beginning, a gentle nag to the wider industry that people want to be able to modify things
2022-01-13T01:52:48 < ventYl_> and the whole industry is a mess
2022-01-13T01:53:32 < kakium69> it serves the industry itself
2022-01-13T01:53:46 < kakium69> nobody wants to get into mess
2022-01-13T01:53:55 < catphish> i guess it is, and always will be, as linux was to the home PC market, an annoying bunch of enthusiasts that break out at times into something useful
2022-01-13T01:54:01 < ventYl_> everyone is there
2022-01-13T01:54:19 < kakium69> true
2022-01-13T01:54:31 < ventYl_> and it costs them a shitload of money
2022-01-13T01:54:38 < ventYl_> like, really, a shitload
2022-01-13T01:54:49 < ventYl_> sometimes 50% of costs are due to group idiocy
2022-01-13T01:54:52 < ventYl_> sometimes even more
2022-01-13T01:55:12 < kakium69> that is job creation ventYl_
2022-01-13T01:55:43 < ventYl_> it requires so many more incompetents / idiots, they couldn't get them
2022-01-13T01:55:57 < kakium69> but yeah I cannot imagine how complex automotive space is
2022-01-13T01:56:09 < ventYl_> it is not really complex
2022-01-13T01:56:13 < ventYl_> it is just a mess
2022-01-13T01:56:28 < ventYl_> problems solved there could be dealt with by simple divide & conquer strategy
2022-01-13T01:56:47 < ventYl_> but then you get one stupid idea and everything goes to hell
2022-01-13T01:56:49 < catphish> i think there will be much more interest in car hacking with EVs
2022-01-13T01:57:27 < kakium69> in the future you hack cars to get rid of manufacturer malwares and goverment tracking codes
2022-01-13T01:57:42 < catphish> while a small hobby, i think it's much bigger than ICE car hacking ever was
2022-01-13T01:58:18 < kakium69> what there is to gain by hacking EVs?
2022-01-13T01:58:18 < ventYl_> luckily, as of now ECUs don't have sufficient power to encrypt all the communication on the bus, so it can at least be wiretapped
2022-01-13T01:58:38 < ventYl_> with newest models, it gets increasingly hard to inject fake data onto bus
2022-01-13T01:58:40 < catphish> though perhaps i have personal bias, because i've wanted to build an EV for the last 5 years
2022-01-13T01:58:53 < ventYl_> which I assume will become a standard once automotive agrees on SOTIF
2022-01-13T01:59:04 < catphish> backend CAN buses are largely still simple and unencrypted
2022-01-13T01:59:20 < ventYl_> that is changing
2022-01-13T01:59:45 -!- upgrdman [~upgrdman@47.180.47.55] has quit [Quit: Leaving]
2022-01-13T01:59:46 < ventYl_> since mr miller fucked up jeep on freeway, OEMs are frightened of safety issues from insecure CAN buses
2022-01-13T02:00:04 < ventYl_> like, there is no term "security" anywhere in automotive. they don't know it
2022-01-13T02:00:13 < ventYl_> all they are dealing with is safety
2022-01-13T02:00:25 < ventYl_> and somehow they understand, that if you fuck up ECU, you can compromise safety
2022-01-13T02:00:33 < catphish> kakium69: that's a good question, i mostly know of repurposing EV parts rather than hacking complete vehicles, but i've also heard of people adding things to them
2022-01-13T02:00:39 < ventYl_> so they derive all their security goals from safety concerns
2022-01-13T02:00:54 < kakium69> oh yes and I forgot
2022-01-13T02:01:38 < kakium69> in future cars are hacked to add features that are implemented into the car but cost moneys to activate
2022-01-13T02:02:07 < ventYl_> probably
2022-01-13T02:02:29 < catphish> ventYl_: i fear they confuse security by obscurity with the more pleasant kind of security which is published for analysis, and offers the owner with the keys full access
2022-01-13T02:03:06 < ventYl_> catphish: in terms of security protocols, those are usually based on open standards, at least for newer equipment
2022-01-13T02:03:08 < catphish> by obfuscating things, they can kick the problem down the road, probably far enough that they make plenty more money and it doesn't ever bite them
2022-01-13T02:03:27 < catphish> in reality, it only upsets people like me
2022-01-13T02:03:37 < catphish> ventYl_: well that's encouraging
2022-01-13T02:03:39 < ventYl_> car SW before year 2000 was a complete jungle, nothing standardized, everything put together in the wildest possible way
2022-01-13T02:04:00 < ventYl_> but you still won't get all the keys, no matter what
2022-01-13T02:04:03 < catphish> i'd much rater see real security, but with the owner (literal key holder) having the keys
2022-01-13T02:04:26 < ventYl_> that won't happen
2022-01-13T02:08:51 < ventYl_> there are legitimate safety and material damage concerns
2022-01-13T02:09:08 < ventYl_> like, one of security levels usually used is "Tier1 production plant"
2022-01-13T02:09:14 < ventYl_> or "OEM production plant"
2022-01-13T02:09:15 < catphish> also, while i may be idealistic, i'm not naive, i realise that manufacturers would prefer to hold the keys, for their own profit, and because "not letting people make unsafe modifications" is by far the easier sell
2022-01-13T02:09:34 < ventYl_> which may be used to allow for access in production plant, such as commands to move something, while car electronics is not fully complete
2022-01-13T02:09:40 < catphish> but i will still continue to campaign for the opposite, for owners being able to work on their own devices
2022-01-13T02:09:56 < ventYl_> such commands are not supposed to be executed after car is finished and usually don't contain any safety measures
2022-01-13T02:10:17 < ventYl_> it is not just about modifications
2022-01-13T02:10:57 < catphish> you say that, but those privileged commands could well be useful for adding functionality
2022-01-13T02:11:08 < kakium69> I welded exhaust pipe today
2022-01-13T02:11:16 < kakium69> it's a bliss
2022-01-13T02:11:21 < kakium69> so silent ride
2022-01-13T02:11:22 < ventYl_> catphish: could you provide an example?
2022-01-13T02:11:23 < catphish> i've never welded anything, this makes me sad
2022-01-13T02:11:33 <@karlp> lol, submit and order request for sale contact, form gives a 500
2022-01-13T02:11:47 < catphish> ventYl_: well an obvious example would be a third party lane follow system
2022-01-13T02:12:01 < kakium69> catphish: point the glue gun at the seam of 2 pieces of steel. press trigger to apply glue
2022-01-13T02:12:12 < catphish> ventYl_: maybe i'm not allowed to command the steering motor, but maybe i'd like to
2022-01-13T02:12:16 < ventYl_> kakium69: i am sad of audium exhaust design. no flexible connection, makes exhaust joints crack
2022-01-13T02:12:31 < BrainDamage> kakium69: welded it closed?
2022-01-13T02:12:35 < catphish> ventYl_: this is hypothetical, but the type of thing a modern car bus could be capable of, with the right access
2022-01-13T02:12:44 < ventYl_> catphish: uh oh, there is so much trouble in this idea
2022-01-13T02:12:47 < ventYl_> mostly technical
2022-01-13T02:12:54 < catphish> ventYl_: of course
2022-01-13T02:13:03 < ventYl_> you don't need access to diagnostics in order to do so
2022-01-13T02:13:15 < catphish> but with proper documentation, that should be my decision
2022-01-13T02:13:41 < ventYl_> well, in car which does not use authentification, you could probably do it with very little RE
2022-01-13T02:13:53 < kakium69> oh.. my problem was that the first stage muffler had it's suspension points rusted off
2022-01-13T02:13:58 < ventYl_> car is not that "secure" once you get physical access
2022-01-13T02:14:16 < kakium69> so the whole pipe was sacking and then cracked
2022-01-13T02:14:23 < catphish> well, sure, and in fact people HAVE added lane assist to card by reverse engineering the power steering CAN bus
2022-01-13T02:14:42 < catphish> but i want to ensure this type of access remains open to the owner
2022-01-13T02:14:54 < catphish> and... ideally... documented!
2022-01-13T02:15:49 < ventYl_> well, there is legitimate safety concern here. OEM can't give pretty much anyone access to power steering control, because it could be used for malicious purposes if security of vehicle was compromised
2022-01-13T02:15:53 < kakium69> just have module to destroy keys when you play with them and then car will tell you that you have modifications in the system
2022-01-13T02:15:54 < ventYl_> which actually already happened
2022-01-13T02:16:03 < kakium69> but keep it operational still
2022-01-13T02:16:29 < catphish> but to back up to someting more simple, VCDS, this tool lets me accurately return errors in all VAG modules, modify settings in them to control settings that a power user might want to change, and reset service timers
2022-01-13T02:16:39 < ventYl_> while the protocol itself could be published (and it is probably not a rocket science anyway, given the way how automotive engineers think), authorization there will probably never be lifted once introduced
2022-01-13T02:16:50 < catphish> this is the kind of thing i really think consumers should have free access to by law
2022-01-13T02:17:21 < catphish> not just generic emissions diagnostics, but full "whatever you take your car to a dealer for" stuff
2022-01-13T02:18:05 < ventYl_> well, how should I explain to you, that when car is made, OEM knows, how much money it will make out of servicing the car?
2022-01-13T02:18:24 < ventYl_> and that this is the real cause for them to not publish that kind of information for free?
2022-01-13T02:18:32 < catphish> ventYl_: you mentioned this, and this is why i think legislation needs to intervene
2022-01-13T02:18:51 < catphish> because i don't like borrowing money to buy things
2022-01-13T02:18:56 < ventYl_> catphish: well, it would probably not make anything good
2022-01-13T02:19:11 < catphish> i don't want to get my car now, but pay some of the cost later, in a hidden manner
2022-01-13T02:19:34 < BrainDamage> I assume you don't use razors
2022-01-13T02:19:36 < BrainDamage> or printers
2022-01-13T02:19:39 < ventYl_> income from post-sales are used to pay for development of new models and partially pay expenses of showrooms
2022-01-13T02:19:48 < kakium69> in future you buy a car and pay also monthly fee to manufacurer
2022-01-13T02:20:03 < kakium69> and if you don't it doesn't move
2022-01-13T02:20:10 < catphish> BrainDamage: you tell me https://i.imgur.com/qc0hKLq.jpg
2022-01-13T02:20:35 < BrainDamage> idea for the future: firmware as a service
2022-01-13T02:20:47 -!- jbgg [~jb@texto-plano.xyz] has joined ##stm32
2022-01-13T02:20:55 < BrainDamage> firmware is downloaded and executed on the fly from the internet
2022-01-13T02:21:04 < catphish> lol
2022-01-13T02:21:05 < kakium69> it's the future BrainDamage
2022-01-13T02:21:10 < ventYl_> since 2020, OTA is a thing with cars
2022-01-13T02:21:11 -!- ferdna [~ferdna@user/ferdna] has joined ##stm32
2022-01-13T02:21:19 < catphish> doesn't tesla already have subscription features :)
2022-01-13T02:21:33 < BrainDamage> not ota, but no builtin functionality at all but the update
2022-01-13T02:21:46 < ventYl_> even in the past, it could happen, that car was released with SW flaw, which eventually got sorted during workshop visit
2022-01-13T02:21:51 < BrainDamage> so it's a useless brick unless it keeps downloading it every start
2022-01-13T02:21:57 < catphish> tesla has OTA updates and PAYG features
2022-01-13T02:22:04 < ventYl_> but now with OTA, cars will probably get released as beta versions
2022-01-13T02:22:08 < kakium69> it's not too hard to imagine that ventYl_
2022-01-13T02:22:23 < catphish> again, see tesla full self driving
2022-01-13T02:22:41 < kakium69> VW even ran updates to their emission scam software
2022-01-13T02:23:06 < ventYl_> they often run SW updates on cars before they leave production plant
2022-01-13T02:23:10 < ventYl_> it happened with id.3
2022-01-13T02:23:18 -!- jbgg [~jb@texto-plano.xyz] has left ##stm32 []
2022-01-13T02:23:28 < catphish> emission scam wasn't a scam, cars just happened to produce less emissions during some driving scenarios ;)
2022-01-13T02:23:29 < ventYl_> even then it was buggy, drained low voltage battery after ~7 days of sitting still
2022-01-13T02:23:39 < kakium69> somebody runs around at car lot with OBD dongle ventYl_?
2022-01-13T02:23:40 < ventYl_> catphish: it was :)
2022-01-13T02:24:18 < kakium69> catphish: it was hmm.. emission optimization software rather
2022-01-13T02:24:23 < ventYl_> kakium69: ventYl_ knows people who know people who know things
2022-01-13T02:24:30 < ventYl_> also, i've seen things myself
2022-01-13T02:24:36 < ventYl_> it was simple
2022-01-13T02:24:46 < ventYl_> emission control test is pretty much standardized
2022-01-13T02:24:58 < ventYl_> the one, which is used for certification
2022-01-13T02:25:06 < ventYl_> ECU can detect it and "adjust"
2022-01-13T02:25:07 < catphish> ventYl_: did they have a full replacement map installed for testing that produced less power and exhaust gases?
2022-01-13T02:25:41 < catphish> that was my understanding, but never really looked into it
2022-01-13T02:25:41 < BrainDamage> just switched to low power mode
2022-01-13T02:25:51 < ventYl_> catphish: no, they just kind of adjusted parameters if ECU detected, that certification test is running
2022-01-13T02:26:13 < BrainDamage> certification testing uses car on a roller bench
2022-01-13T02:26:22 < BrainDamage> doesn't strain the engine, etc
2022-01-13T02:26:24 < ventYl_> with diesel engine, you can play with mixture a lot
2022-01-13T02:26:26 < catphish> so entered some kind of eco mode when oddly specific criteria were met?
2022-01-13T02:26:33 < kakium69> those parameters caused soothing and eventually blocked particle filter if it stayed enabled on the road
2022-01-13T02:26:53 < kakium69> so update was introduced
2022-01-13T02:27:00 < ventYl_> the thing is, that VW did not do it
2022-01-13T02:27:13 < catphish> oh, some people ended up in testing mode permanently?
2022-01-13T02:27:23 < ventYl_> as VW does not really make any engine control units
2022-01-13T02:27:33 < kakium69> oh
2022-01-13T02:27:43 < catphish> bosch make VAG ECUs don't they?
2022-01-13T02:28:07 < ventYl_> depends, some are from bosch, some are from magnetti marelli, some are from siemens, some might be from others
2022-01-13T02:28:07 < catphish> and indeed most other parts
2022-01-13T02:28:17 < ventYl_> there are like 10 manufacturers of engine control systems
2022-01-13T02:28:35 < catphish> i built an ECU last year, it sucked
2022-01-13T02:28:49 < BrainDamage> the manifacturer added the scam feature
2022-01-13T02:28:50 < kakium69> why did you do such thing catphish?
2022-01-13T02:28:59 < catphish> kakium69: for learnings
2022-01-13T02:29:00 < BrainDamage> and wv intentionally enabled it
2022-01-13T02:29:07 < ventYl_> BrainDamage: who? VW? VW doesn't have access to ECU SW
2022-01-13T02:29:09 < ventYl_> neither can alter it
2022-01-13T02:29:11 < BrainDamage> because it was off by default
2022-01-13T02:29:25 < BrainDamage> it can set the params
2022-01-13T02:29:35 < ventYl_> i've been told, that ECU manufacturer was "offering" it to various OEMs
2022-01-13T02:29:39 < BrainDamage> it was part of configuration
2022-01-13T02:29:42 < BrainDamage> yes
2022-01-13T02:29:50 < kakium69> ventYl_: and all of them used it
2022-01-13T02:29:55 < ventYl_> basically
2022-01-13T02:30:07 < catphish> kakium69: https://www.youtube.com/watch?v=K-y3dsq0RuE
2022-01-13T02:30:34 < kakium69> yes that one
2022-01-13T02:30:52 < catphish> STM32 controlling (badly) the injectors and ignition
2022-01-13T02:31:03 < kakium69> somebody did "freevalve" for B&S
2022-01-13T02:31:13 < kakium69> it was on youtubes
2022-01-13T02:31:28 < ventYl_> catphish: interesting. i want to make ignition ECU for my older car
2022-01-13T02:31:56 < kakium69> some pneumatic cylinders with damn fast valve solenoid blocks driving them
2022-01-13T02:32:06 < catphish> ventYl_: my only recommendation is not to do it the way i did :)
2022-01-13T02:32:42 < catphish> but more seriously it's definitely possible, and there's open source ECUs already that work well for older cars
2022-01-13T02:32:56 < ventYl_> catphish: well, in my case the trouble is that the car has mechanical distributor I want to retain (to retain the original look)
2022-01-13T02:33:00 < kakium69> ventYl_: does ignition ecu even need any smart function?
2022-01-13T02:33:20 < ventYl_> there is mechanically compatible distributor, but that contains inductive pickup
2022-01-13T02:33:28 < ventYl_> that inducet a looooooooot of voltage
2022-01-13T02:33:33 < ventYl_> *induces
2022-01-13T02:33:40 < catphish> ventYl_: mechanical distributor doesn't have to be connected to anything :)
2022-01-13T02:33:42 < ventYl_> kakium69: define smart function
2022-01-13T02:33:56 < ventYl_> catphish: i don't want to drill additional holes for additional sensors
2022-01-13T02:33:56 < catphish> ventYl_: or you can open it and replace the insides with a rotary encoder
2022-01-13T02:34:31 < catphish> a toothed wheel encoder might fit inside the distributor
2022-01-13T02:34:50 < ventYl_> catphish: i have found some circuits which should work with inductive pickups without actually frying the MCU
2022-01-13T02:34:59 < BrainDamage> does it still output a stupidly high voltage on a low impedance?
2022-01-13T02:35:19 < ventYl_> yet still might throw it out, because the signal looks silly
2022-01-13T02:35:36 < catphish> ventYl_: it should be easy to detect pulses from inductive pickups
2022-01-13T02:35:38 < kakium69> ventYl_: calculations
2022-01-13T02:35:51 < ventYl_> BrainDamage: mostly yes, there's a permanent magnet inside it, so it is rather strong source of voltage
2022-01-13T02:36:14 < ventYl_> kakium69: some do, like knock control maintained for each separate cylinder
2022-01-13T02:36:28 < kakium69> hmm
2022-01-13T02:37:22 < catphish> should be possible to build something that sinks the energy while detecting a voltage, not dissimilar to what i've been doing, low impedance voltae divider, zener, bjt, digital output
2022-01-13T02:37:31 < ventYl_> also, you need to maintain charge constant, so you need to calculate when to start charging the coil and when to fire the spark
2022-01-13T02:37:51 < ventYl_> catphish: it doesn't generate "pulses" per se
2022-01-13T02:37:54 < ventYl_> that would be simple
2022-01-13T02:37:55 < ventYl_> wait
2022-01-13T02:38:05 < BrainDamage> catphish: one annoying thing is that the output voltage is directly proportional to the rpm
2022-01-13T02:38:24 < BrainDamage> because higher rpm = higher db/dt
2022-01-13T02:38:49 < catphish> BrainDamage: yes it is indeed, but with a bjt this doesn't necessarily matter, as long as you limit it
2022-01-13T02:38:55 < ventYl_> catphish: https://www.picoauto.com/images/uploads/agt/AT428_WAVEFORM_FORMATION.png
2022-01-13T02:39:04 < ventYl_> this kind of waveform is generated by my pickup
2022-01-13T02:39:07 < catphish> just make a current sink
2022-01-13T02:39:27 < ventYl_> you are supposed to fire when signal changes polarity from negative to positive
2022-01-13T02:39:54 < ventYl_> precision of detection of that point vastly depends on zero-crossing detection abilities, so no offset, no nothing
2022-01-13T02:40:05 < catphish> ventYl_: anyway, the general approach is to collect as many pulses as possible per revolution, use them to calculate 1) rpm 2) rotational position based on rpm and last recorded position
2022-01-13T02:40:26 < catphish> once you have all that, you can fire ignition at any position you like
2022-01-13T02:40:29 < ventYl_> catphish: all you have there are two pulses per revolution. one per cylinder :)
2022-01-13T02:40:53 < catphish> ventYl_: yap, that can work though, mine had one :)
2022-01-13T02:40:54 < ventYl_> kakium69: and yeah, you have to derive engine load somehow
2022-01-13T02:41:16 < ventYl_> catphish: i need to derive the circuit, which will do zero crossing detection and then it will be fine
2022-01-13T02:41:20 < catphish> at a minimum, you need throttle position sensor too
2022-01-13T02:41:25 < ventYl_> I had something but then I abandonned the project for other work
2022-01-13T02:41:29 < kakium69> ah
2022-01-13T02:41:35 < kakium69> my moped has TPS
2022-01-13T02:41:42 < ventYl_> catphish: nope, carb doesn't have one
2022-01-13T02:41:53 < catphish> ventYl_: in your case i'd not do zero crossing, but crossing some arbitrary positive position
2022-01-13T02:41:54 < kakium69> and 2 timing angles for ignition
2022-01-13T02:42:01 < ventYl_> but there is vacuum port... below throttle
2022-01-13T02:42:20 < ventYl_> catphish: that arbitrary positive position shifts from "ideal zero" depending on RPM
2022-01-13T02:42:24 < ventYl_> quite a lot
2022-01-13T02:42:37 < catphish> with my bjt concept, you get a rising edge at a particular input threshold, like 0.7v
2022-01-13T02:43:01 < catphish> which is essentially the zero crossing, but perhaps ignoreing the missing tooth
2022-01-13T02:43:06 < ventYl_> yeah, but at 300 RPM (cranking speed), peak voltage output is like 10V, at 3000, peak output is like 1000V
2022-01-13T02:43:14 < ventYl_> which makes 0.7V vary greatly
2022-01-13T02:43:22 < ventYl_> on waveform
2022-01-13T02:43:38 < ventYl_> at 300 RPM, 0.7V may be like 50* ATDC
2022-01-13T02:43:42 < catphish> ventYl_: you're correct, this is why you need some kind of energy sink too
2022-01-13T02:43:59 < ventYl_> at 3000, it will be roughly at TDC
2022-01-13T02:44:37 < BrainDamage> you can add an agc, rectify all outputs, throw them in a cap, and use that to select the voltage divider
2022-01-13T02:44:40 < catphish> i wouldn't like to guess how you handle 10v to 1000v, but i suspect some diodes will help
2022-01-13T02:45:23 < catphish> diodes may be able to dissipate anything above 0.7v
2022-01-13T02:45:29 < catphish> or they may blow up, i'm not certain
2022-01-13T02:45:40 < qyx> just add an encoder to the shaft? :x
2022-01-13T02:45:50 < ventYl_> there is some circuit which shall handle that stuff
2022-01-13T02:45:54 < catphish> well that was my first suggection
2022-01-13T02:45:56 < BrainDamage> that was mentioned as #1 solution
2022-01-13T02:46:02 < qyx> oh
2022-01-13T02:46:16 < ventYl_> it is basically reference circuit for some IC used in common ignotor controllers
2022-01-13T02:46:35 < catphish> in my engine, i removed the magnet, and connected the distributor contacts to 3v3
2022-01-13T02:46:47 < ventYl_> qyx: nah, too harsh conditions. shitload of vibrations and high temperatures
2022-01-13T02:47:12 < catphish> so i kept the mechanical switches, but without the magnetically induced energy
2022-01-13T02:47:28 < ventYl_> that's actually a downgrade :D
2022-01-13T02:47:41 < ventYl_> decreases lifetime of mechanical switches
2022-01-13T02:47:44 < catphish> this is a terrible idea, because of noise, but it can be improved upon
2022-01-13T02:48:02 -!- System_Error [~SystemErr@user/systemerror] has quit [Remote host closed the connection]
2022-01-13T02:48:07 < ventYl_> such solution was used in OEM ignition systems only for short time period
2022-01-13T02:48:47 < catphish> it really should be possible to detect OEM magnetic spikes though
2022-01-13T02:48:57 -!- System_Error [~SystemErr@user/systemerror] has joined ##stm32
2022-01-13T02:49:05 < BrainDamage> it's absolutely possible
2022-01-13T02:49:12 < ventYl_> if switch has a cap and switches primary of coil, the current over switch is actually AC
2022-01-13T02:49:16 < BrainDamage> you just don't want it cost an arm and a leg
2022-01-13T02:49:40 < ventYl_> if you wire 3V3 there, it becomes DC, at that switch rate, material migration occurrs which causes premature failure of the switch
2022-01-13T02:50:00 < catphish> fwiw i once hacked a rowing machine, this had megnets passing a coil to measure speed, i wired the pickup magnet to a sound card input and it was fine, i'm not saying this is a good idea, but with a small load, that 1000v may not be unmanagable at all
2022-01-13T02:51:16 < ventYl_> i'll hopefully come back to this project once
2022-01-13T02:51:25 < ventYl_> now that I have raspberry pi nanos, it is more likely
2022-01-13T02:51:33 < ventYl_> as atmega is pain in the ass for me now
2022-01-13T02:51:58 < catphish> i hope you mean picos
2022-01-13T02:52:02 < ventYl_> ok, time to sleep
2022-01-13T02:52:05 < ventYl_> yeah, picos
2022-01-13T02:52:08 < catphish> :)
2022-01-13T02:52:13 < catphish> i'm a big fan
2022-01-13T02:52:16 < catphish> enjoy sleep
2022-01-13T02:52:23 < ventYl_> I bought five of them
2022-01-13T02:52:31 < ventYl_> and will probably replace every atmega with them
2022-01-13T02:53:16 < catphish> i bought a batch of 10 for my EV BMS experiments
2022-01-13T02:53:23 < catphish> they're working nicely
2022-01-13T02:53:42 < ventYl_> i have some instability with debugging interface
2022-01-13T02:53:51 < ventYl_> but that might be due to the fact, that I am working with it bare metal
2022-01-13T02:54:01 < BrainDamage> a 16 bit ADC on a 1V ref will give you 15uV resolution, if you scale your input by 1000, a 10V you still have 9 bits of resolution
2022-01-13T02:54:11 < catphish> the castled cheap dev board makes it super easy to use in small run prototypes without having to do much design work
2022-01-13T02:54:28 < catphish> i haven't used debug interface
2022-01-13T02:54:31 < BrainDamage> and if 9 bits aren't enough, 24 bit adc should be possible still
2022-01-13T02:54:50 < BrainDamage> so a simple resistor divider and isolation amp will work
2022-01-13T02:54:51 < kakium69> BrainDamage: 16bits requires effort already
2022-01-13T02:54:54 < ventYl_> it sometimes locks up, but stlink does so too
2022-01-13T02:55:10 < ventYl_> BrainDamage: there's also a shitload of noise around there
2022-01-13T02:55:11 < catphish> BrainDamage: the answer isn't resolution, it's compression / clampint
2022-01-13T02:55:17 < catphish> *clamping
2022-01-13T02:55:37 < BrainDamage> catphish: I already suggested an agc system
2022-01-13T02:55:42 < catphish> you want 1v to give you a logic high, and 1000v to give logic high
2022-01-13T02:55:47 < ventYl_> ok, i am going to bed now, otherwise, I will go and search for breadboard where that circuit is prototyped
2022-01-13T02:56:16 < catphish> hence my suggestion of diode, resistor, zener, transistor
2022-01-13T02:56:26 < catphish> or anything that has a wide input and clipped output
2022-01-13T02:56:33 < catphish> but needs a lot more playing
2022-01-13T02:56:40 < catphish> lol sleep good
2022-01-13T02:56:57 < BrainDamage> a tvs diode would work better, but you'll be working with significant amount of energies being dumped
2022-01-13T02:57:19 < BrainDamage> up to the point where you'll have to consider the lifetime of the device
2022-01-13T02:57:20 < catphish> yes, you're right
2022-01-13T02:57:47 < BrainDamage> because they are rated for few millions / billions discharges
2022-01-13T02:57:55 < BrainDamage> and the engine works at thousands rpm
2022-01-13T02:58:30 < BrainDamage> and 10^6s is just little more than 10 days
2022-01-13T02:59:19 < catphish> but... dump energy through a resistor divider, then apply high gain to the voltage
2022-01-13T02:59:34 < catphish> and you might have something robust
2022-01-13T03:00:05 < BrainDamage> at that point you're back to the adc design :p
2022-01-13T03:00:20 < catphish> not with enough gain :)
2022-01-13T03:00:47 < catphish> but noise questions arise
2022-01-13T03:02:51 < BrainDamage> ok, i might have a better idea
2022-01-13T03:03:14 < BrainDamage> replace magnet with a weaker one, and place a weak saturable core in the pickups
2022-01-13T03:03:49 < BrainDamage> at high rpms the core saturate, the inductance drop and the output voltage stops climbing so high
2022-01-13T03:07:20 < BrainDamage> alternatively, replace permanent magnet with electromagnet which gets controlled by the pulses, the more pulses, the weaker it gets
2022-01-13T03:07:26 < BrainDamage> so it self stabilizes
2022-01-13T03:07:29 < catphish> BrainDamage: this is the kind of thing i mean, clearly some adjustment needed https://tinyurl.com/yyr348rw - this works at pretty much any input voltage, but i have no idea of the real life implications of high energy pulses
2022-01-13T03:09:13 < catphish> the simplified falstad mode works with a 1v or a 1000v sine wave
2022-01-13T03:09:37 < catphish> the reality is likely more complicated
2022-01-13T03:09:53 < catphish> *model
2022-01-13T03:10:31 < BrainDamage> start adding a series resistor from source impedance
2022-01-13T03:10:46 < BrainDamage> because the coil won't provide infinite power
2022-01-13T03:11:15 < catphish> i was just thinking about that, a coil is neither a voltage nor a current source, but it should be modelable
2022-01-13T03:13:17 < catphish> at that point, the model becomes https://tinyurl.com/y5ag3err
2022-01-13T03:13:33 < catphish> but again, i'm obviously grossly oversimplifying the coil source model
2022-01-13T03:14:11 < catphish> but the fact it can't provide infinite energy is exactly why i feel like driving a BJT with it might be okay
2022-01-13T03:14:29 < catphish> because ultimately most of the voltage is across the base resistor
2022-01-13T03:15:13  * catphish is only getting started with this analog stuff though!
2022-01-13T03:15:48  * catphish sleep now

2022-01-13T09:29:41 < Xogium> you guys have any tips to avoid wires popping off of gpio pins when breadboarding ? It's super annoying
2022-01-13T09:30:09 < Xogium> I connected my IR receiver fine, but now at the slightest move of my board the wires disconnect from the pins
2022-01-13T09:30:39 < jpa-> better quality wires
2022-01-13T09:30:52 < Xogium> hmm
2022-01-13T09:30:55 < BrainDamage> bread boards are notoriously unreliable, check wire diameter vs hole diameter
2022-01-13T09:31:08 < Xogium> the breadboard part is fine
2022-01-13T09:31:12 < BrainDamage> and if you're using binding posts, square vs circle
2022-01-13T09:31:21 < jpa-> and yeah, better quality breadboard also - but both of these are annoyingly difficult to judge even from photos, let alone without them
2022-01-13T09:31:26 < Xogium> it's the pins I connect it to that keep falling off
2022-01-13T09:31:58 < BrainDamage> what's the diameter of the wire?
2022-01-13T09:32:06 < Xogium> 2.54 mm
2022-01-13T09:35:07 < BrainDamage> sounds right :/
2022-01-13T09:35:24 < BrainDamage> try moving to a diff section
2022-01-13T09:35:39 < BrainDamage> and jiggle by hand to judge how firm is the hold
2022-01-13T09:35:46 < Xogium> could be also because of the weight of my breadboard ? Not sure
2022-01-13T09:36:14 < BrainDamage> no, the pins are held inside by friction
2022-01-13T09:36:30 < BrainDamage> there's a V shaped spring which squeezes the wire when's plugged
2022-01-13T09:36:32 < Xogium> right, but what about the pins on my board ?
2022-01-13T09:36:48 < Xogium> they are the one that keep disconnecting from the wires
2022-01-13T09:37:11 < Xogium> the hold on the breadboard side is pretty secure
2022-01-13T09:37:23 < BrainDamage> ooohh, I thought the opposite
2022-01-13T09:38:06 < Xogium> nah must have been lucky and picked a good breadboard and hopefully wires kit
2022-01-13T09:38:09 < BrainDamage> what kind of receptacle does your board have? male or femaae?
2022-01-13T09:38:12 < Xogium> but yeah… not too sure
2022-01-13T09:38:19 < Xogium> male pins
2022-01-13T09:38:30 < BrainDamage> square or round?
2022-01-13T09:38:50 < Xogium> er… you mean the shape of the pins ?
2022-01-13T09:38:53 < BrainDamage> yes
2022-01-13T09:39:02 < BrainDamage> you can easily tell by touch
2022-01-13T09:40:50 < Xogium> hmm honestly hard to tell
2022-01-13T09:40:58 < Xogium> they are super close together
2022-01-13T09:41:09 < BrainDamage> round pins are normally meant to be soldered, square instead is for manual connection
2022-01-13T09:41:17 < Xogium> it is the stm32mp157f-dk2 board, for what its worth
2022-01-13T09:41:32 < Xogium> probably square, then
2022-01-13T09:41:34 < BrainDamage> and if you want to fit dupont style connectors on round pins, you should pick them smaller
2022-01-13T09:41:40 < Xogium> they are rpi compatible headers
2022-01-13T09:42:25 < BrainDamage> they are square
2022-01-13T09:42:39 < BrainDamage> dupont females should hold them ok
2022-01-13T09:42:56 < BrainDamage> try fitting neighbour pins even if they aren't wired
2022-01-13T09:43:02 < Xogium> yeah
2022-01-13T09:43:03 < BrainDamage> so they won't jiggle laterally
2022-01-13T09:43:30 < BrainDamage> alternatively, get a ribbon cable, and plug over the entire pin terminal strip
2022-01-13T09:43:31 < Xogium> hmm
2022-01-13T09:43:37 < BrainDamage> then separate the wires and use those
2022-01-13T09:43:48 < Xogium> I didn't know that existed
2022-01-13T09:44:26 < BrainDamage> the world knows them as ide cables
2022-01-13T09:44:33 < BrainDamage> the ones of the hard disk
2022-01-13T09:46:01 < BrainDamage> the wires are glued in a flat shape, you'll have to cut it, sepate the wires, and then strip  the heads
2022-01-13T09:46:18 < BrainDamage> but it has the advantage that it'll retain easily counting
2022-01-13T09:46:53 < BrainDamage> and it'll fit snugly on the rpi style binding post strip
2022-01-13T09:47:12 < Xogium> I woncer why individual wires don't fit that good
2022-01-13T09:47:15 < Xogium> *wonder
2022-01-13T09:47:49 < Xogium> even the wires that were attached to the rpi fan I got, I'm lucky the case hold them down from above
2022-01-13T09:48:51 < BrainDamage> because binding post height is not standard
2022-01-13T09:49:15 < BrainDamage> and in order to fit all of them, they tend to be longer than necessary
2022-01-13T09:49:15 < Xogium> oh
2022-01-13T09:49:30 < BrainDamage> being too long makes them weak to lateral solecitations
2022-01-13T09:49:45 < Xogium> yeah that makes sense
2022-01-13T09:49:46 < BrainDamage> so they jiggle away and pop off
2022-01-13T09:49:56 < BrainDamage> that's why I suggested to plug even unused ones
2022-01-13T09:50:10 < BrainDamage> because they limit lateral movements, and will help keeping them there
2022-01-13T09:50:19 < Xogium> makes sense
2022-01-13T09:50:38 < Xogium> and its probably what the top of the rpi case I got for my other board does, holding the wires of the fan into place
2022-01-13T09:50:58 < Xogium> it put just enough pressure so they can't move too much
2022-01-13T09:52:49 < Xogium> though, if I'm lucky, the same will happen when I'll put the lcd back on this one… I won't cound on it though
2022-01-13T09:53:16 < Xogium> I had to remove it to get access to the gpio

2022-01-13T12:32:21 < Steffann> I'll report it as data breach. Although it's probably not that

2022-01-13T12:36:59 < mawk> we're adding a neural net magic thing that removes faces from images before saving them to database

2022-01-13T12:44:10 < ventYl_> is one random shot containing face without no context even covered by GDPR?
2022-01-13T12:44:22 < mawk> the boss thinks so 
2022-01-13T12:44:49 < ventYl_> like, I understand, that google street view has some context, so there GDPR should be applied
2022-01-13T12:45:00 < mawk> well here's there time and date and place associated with the photo
2022-01-13T12:45:07 < mawk> it's as much context as google street view
2022-01-13T12:45:15 < ventYl_> ok, that's different
2022-01-13T12:49:26 < catphish> public photos of people are subject to GDPR, so if you publish them, you need to determine your grounds for doing so, and have appropriate policies in place

2022-01-13T12:52:14 < BrainDamage> what pisses me the most is how most websites found a loophole in the gdpr anti tracking law
2022-01-13T12:52:43 < BrainDamage> anti tracking law mandates all tracking features off by default, and they are if they comply
2022-01-13T12:53:06 < mawk> it's not just publishing catphish 
2022-01-13T12:53:09 < mawk> just storing internally isn't allowed
2022-01-13T12:53:17 < mawk> i.e. in case of data breach
2022-01-13T12:53:26 < BrainDamage> but then to proceed you need to either press the button to switch them all back on instantly, or go to settings and save ... the settings that were already switched off
2022-01-13T12:53:27 < mawk> or in case of employees using private info to harrass girls or something
2022-01-13T12:53:38 < mawk> yeah BrainDamage 
2022-01-13T12:53:49 < mawk> or sometimes you have to untick one by one all the stuff enabled by default
2022-01-13T12:53:55 < mawk> and there's like 10 items
2022-01-13T12:54:04 < BrainDamage> that's illegal under gdpr
2022-01-13T12:54:11 < BrainDamage> they should be off by default
2022-01-13T12:54:16 < mawk> yeah
2022-01-13T12:54:19 < ventYl_> 10?
2022-01-13T12:54:32 < BrainDamage> some sites have hundreds
2022-01-13T12:54:33 < mawk> I guess the perspective of punishment isn't scary enough
2022-01-13T12:54:47 < mawk> sometimes the CNIL of various countries will issue a warning, and then they fix it
2022-01-13T12:54:54 < mawk> no financial harm done
2022-01-13T12:55:06 < ventYl_> i've even seen some website evangelist even ranting about new set of GDPR restrictions, which limits them on processing of visitor data
2022-01-13T12:55:41 < ventYl_> completely ignoring the fact that the practices of processing visitor data caused emerge of GDPR in first place
2022-01-13T12:56:12 < BrainDamage> gdpr allows in the case of necessary service
2022-01-13T12:56:28 < ventYl_> 99% is not necessary service
2022-01-13T12:56:42 < ventYl_> and this specific rant was about analytics
2022-01-13T12:58:02 < BrainDamage> I wonder if there's a way to fix the loophole they are using, because they are using anti-patterns relying on user confusion/lazyness to have them consent to tracking
2022-01-13T12:58:08 < BrainDamage> which is pretty much a scam
2022-01-13T12:59:14 <@karlp> well, there's still the legitimate interest bullshit
2022-01-13T12:59:54 < ventYl_> well, one way to fix this would be to feed it so much bogus data, all the analytics will become useless, or at least non-representative
2022-01-13T13:00:39 < ventYl_> like with all those "we will send you a sample" whichc turns out to be "by receiving this sample you agreed to one monthly shipment with yearly fee of $999 and one year termination period"
2022-01-13T13:01:00 < ventYl_> give those people so many plausible enough addresses which lead to nowhere, they will be afraid to pay the costs
2022-01-13T13:08:44 < mawk> yes BrainDamage our CNIL seems to think it's illegal
2022-01-13T13:08:48 < mawk> and warned facebook I think about it
2022-01-13T13:08:52 < mawk> or even inflicted a penalty
2022-01-13T13:08:58 < mawk> but it's a few million euros it's nothing for them
2022-01-13T13:09:36 < BrainDamage> it boggles my mind how fines are always fixed amounts and not some % of gross profit
2022-01-13T13:10:10 < BrainDamage> and if they are concerned about people faking their income, you can always use both and take the highest
2022-01-13T13:10:59 < ventYl_> even then, it would be taken as part of "costs", just like if penalty is some % of income, our costs will increase by that many % if we employ this strategy

2022-01-13T15:02:47 < ventYl_> depends on way of returning -4
2022-01-13T15:02:54 < ventYl_> if command echoes -4, then yes, otherwise not

2022-01-13T15:06:31 < Laurenceb> exit(-4) in c
2022-01-13T15:06:43 < PaulFertser> Laurenceb: then do this: ./command; s=$?

2022-01-13T15:07:32 < PaulFertser> Laurenceb: or just make the program return 0 if everything is fine and something else if not.
2022-01-13T15:08:22 < Laurenceb> ok wtf now s is 252
2022-01-13T15:08:27 < Laurenceb> looks like unsigned 8 bit ints

2022-01-13T15:15:42 < PaulFertser> Laurenceb: return code is kept in process control block in the kernel, in the same place as sigmask, current working directory etc
2022-01-13T15:16:22 < PaulFertser> Laurenceb: if you need more than that guess you can print it on stdout or stderr, what's the problem?

2022-01-13T15:26:47 < mawk> you don't return -anything by any syscall that you call through the libc Laurenceb

2022-01-13T15:27:40 < ventYl_> mawk: pclose seems to be an exception to that rule
2022-01-13T15:27:50 < zyp> mawk, how's the covid? did you die yet?
2022-01-13T15:28:09 < mawk> what do you mean ventYl_ 
2022-01-13T15:28:13 < mawk> the man page says it returns -1
2022-01-13T15:28:32 < mawk> not yet zyp 
2022-01-13T15:28:32 < catphish> pclose shold return the exit code
2022-01-13T15:28:36 < mawk> I had to go back to work
2022-01-13T15:28:46 < zyp> awh
2022-01-13T15:28:46 < catphish> "pclose():  on  success,  returns  the  exit  status  of the command"
2022-01-13T15:29:14 < mawk> yes but that's not an error status catphish 
2022-01-13T15:29:17 < mawk> and that's a positive number
2022-01-13T15:29:23 < mawk> exit status are between 0 and 127
2022-01-13T15:29:27 < zyp> aren't always exit status positive?
2022-01-13T15:29:32 < zyp> yeah
2022-01-13T15:29:43 < Laurenceb> arg sheeet
2022-01-13T15:30:02 < mawk> you want to pass numbers between threads/processes Laurenceb ?
2022-01-13T15:30:04 < mawk> use eventfd
2022-01-13T15:30:12 < mawk> or signals
2022-01-13T15:30:19 < Laurenceb> ok
2022-01-13T15:30:38 < mawk> eventfd is very easy to use, you just write() on it from one side, and you read() the number on the other side
2022-01-13T15:30:40 < Laurenceb> yeah I need to be able to pass a status code or an error code
2022-01-13T15:30:42 < catphish> right, exit code is positive integer, so -4 isn't going to work
2022-01-13T15:30:42 < mawk> it can transmit 8-byte numbers
2022-01-13T15:31:13 < catphish> though what happens if you return -4 (ie set the 8th bit)? i've never thought to try this
2022-01-13T15:31:30 < mawk> I tried it before but I forgot what happens
2022-01-13T15:31:35 < mawk> probably it gets mod 128
2022-01-13T15:31:41 < catphish> i'd just use the io stream
2022-01-13T15:31:43 < ventYl_> i have just decided that I will actively disrupt HR operations by avoiding any action which would save dumb HR it's time
2022-01-13T15:31:52 < mawk> because return values above 128 mean that the process was killed
2022-01-13T15:32:05 < mawk> using io stream so you mean a regular pipe catphish ?
2022-01-13T15:32:09 < catphish> mawk: yes
2022-01-13T15:32:17 < mawk> opening a pipe for stdout of the process, and reading on it
2022-01-13T15:32:25 < mawk> yeah you could do that, if eventfd isn't portable enough
2022-01-13T15:32:32 < mawk> but it's a bit more machinery
2022-01-13T15:32:55 < catphish> should be possible to make a pipe() and have the child process write its stdout to it
2022-01-13T15:33:00 < mawk> or if you need to transmit more than just a 8-byte numbers then a pipe is good
2022-01-13T15:33:07 < mawk> yeah
2022-01-13T15:33:26 < catphish> it's not *that* much extra work, even if you do only need to send 1 byte
2022-01-13T15:33:43 < mawk> yeah not much extra work for the programmer
2022-01-13T15:34:09 < catphish> in fact, popen created the pipe for you?
2022-01-13T15:34:16 < catphish> you just need to read() from it
2022-01-13T15:34:51 < catphish> popen():  on  success,  returns a pointer to an open stream that can be used to read or write to the pipe
2022-01-13T15:35:01 < catphish> so pretty much trivial
2022-01-13T15:40:39 < Laurenceb> ok I just tested it
2022-01-13T15:40:53 < Laurenceb> it returns a 16bit unsigned int
2022-01-13T15:42:31 <@karlp> "tested"
2022-01-13T15:42:35 < mawk> popen is if you want to call a command directly yes catphish 
2022-01-13T15:42:47 < mawk> tested what Laurenceb 
2022-01-13T15:43:08 < mawk> why are you never doing things the right way 
2022-01-13T15:43:12 < Laurenceb> popen with -ive and +ive return codes
2022-01-13T15:43:31 < mawk> yes the process return code isn't the best place to send information I suppose
2022-01-13T15:43:32 < Laurenceb> ok so its return code from the command << 8 | error status
2022-01-13T15:44:04 < mawk> are you sure
2022-01-13T15:44:12 < mawk> I have a feeling it just returns the exit code
2022-01-13T15:44:17 < Laurenceb> looks like it on debian at least
2022-01-13T15:44:18 < mawk> and -1 on error
2022-01-13T15:44:38 < mawk> if you're opening a pipe why are you not using the pipe itself for the status code
2022-01-13T15:44:47 < Laurenceb>  -1 returned by the command isnt the same as a -1 error from the pipe or interpretter
2022-01-13T15:44:58 < mawk> -1 returned by the command isn't really allowed
2022-01-13T15:45:04 < mawk> commands return between 0 and 127
2022-01-13T15:45:09 < mawk> if you return something outside that range it's undefined
2022-01-13T15:45:34 < mawk> and above 128 it means a signal killed the command
2022-01-13T15:45:36 < mawk> 128 + signal
2022-01-13T15:45:49 < Laurenceb> thats not how its behaving
2022-01-13T15:46:18 < mawk> well you tried it with a negative number, so it's behaving how I said it behaves in that case: in undefined manner
2022-01-13T15:46:51 < Laurenceb> its treating return code as unsigned 8 bit int, shifting up 8bits then bitwise or with the pipe/interpretter error code
2022-01-13T15:47:47 < Laurenceb> I only need internal and external error codes (+ive or -ive), this should be ok tbh
2022-01-13T15:50:34 < mawk> you can't have external negative codes with that
2022-01-13T15:51:04 < mawk> and you have no way of knowing what broke, if it's your shell command or if it's your program
2022-01-13T15:51:10 < mawk> popen() just starts a dumb shell
2022-01-13T15:54:36 < mawk> open an eventfd on fd 9, then start your program
2022-01-13T15:54:41 < mawk> and your program just has to write() to fd 9
2022-01-13T15:54:43 < mawk> as simple as that
2022-01-13T15:55:19 < Laurenceb> ok
2022-01-13T15:55:37 < Laurenceb> but how is that linked between the two threads?
2022-01-13T15:55:38 < mawk> if you keep using pclose() like this I don't think you can safely have values outside 0-127
2022-01-13T15:56:00 < mawk> well all files you open before starting a thread/process will stay open
2022-01-13T15:56:31 < mawk> if you open a eventfd and it has fd = 42 for instance, then all child threads and processes can write into the fd 42
2022-01-13T15:56:34 < mawk> and parent process can read from it
2022-01-13T15:59:45 < Laurenceb> oh ok, so the number 42 has to be unique?
2022-01-13T16:00:44 < mawk> well you don't chose it yourself, you just do eventfd() and a random number is assigned
2022-01-13T16:00:54 < mawk> then you give that number to your threads and processes
2022-01-13T16:01:02 < mawk> alternatively you can force the number to be something like 9, it's never used
2022-01-13T16:01:18 < mawk> by the way I looked at your pclose, it's not documented but I looked at the code, now I know what the status is
2022-01-13T16:01:26 < mawk> it's the same thing as returned by the wait() syscall
2022-01-13T16:01:32 < mawk> it's a number you're supposed to inspect with macros
2022-01-13T16:01:46 -!- mawk [mawk@wireguard/contributor/mawk] has left ##stm32 [Leaving]
2022-01-13T16:01:50 -!- mawk [mawk@wireguard/contributor/mawk] has joined ##stm32
2022-01-13T16:01:58 < mawk> you do WEXITSTATUS(status) on the number to get the exit status
2022-01-13T16:02:06 < mawk> and that may or may not be just status >> 8, that depends on implementation
2022-01-13T16:02:22 < mawk> so if you keep using pclose, then use that macro (and keep the status between 0 and 127 for maximum portability)
2022-01-13T16:03:06 < mawk> https://sourceware.org/git/?p=glibc.git;a=blob;f=libio/iopopen.c;h=06778cf110ef9b2745664df00bfd37f291e23ff3;hb=HEAD#:~:text=288%20%20%20while%20(wait_pid%20%3D%3D%20%2D1%20%26%26%20errno%20%3D%3D%20EINTR)%3B
2022-01-13T16:03:08 < mawk> you can see it here
2022-01-13T16:03:49 < mawk> it does « wait_pid = __waitpid (((_IO_proc_file *) fp)->pid, &wstatus, 0); » and ultimately that's what is returned by pclose(3)
2022-01-13T16:06:08 < mawk> for instance your child program contains this Laurenceb : https://paste.serveur.io/KVXQVq21.c
2022-01-13T16:06:25 < mawk> argv[1] contains like /proc/self/42 which is the path to the eventfd the parent process opened
2022-01-13T16:06:35 < mawk> and in the parent process you open the eventfd then give its number to the child
2022-01-13T16:07:17 < Laurenceb> oh I see, and thats passed to the subprocess, I see now
2022-01-13T16:08:50 < Laurenceb> oh any my question is answered here  https://www.tutorialspoint.com/unix_system_calls/waitpid.htm
2022-01-13T16:09:03 < Laurenceb> there are some macros for manipulating the return code
2022-01-13T16:10:00 < mawk> that's exactly what I told you Laurenceb 
2022-01-13T16:10:00 < mawk> :(
2022-01-13T16:10:08 < mawk> [15:01:58] <mawk> you do WEXITSTATUS(status) on the number to get the exit status
2022-01-13T16:10:09 < mawk> [15:01:26] <mawk> it's the same thing as returned by the wait() syscall
2022-01-13T16:10:21 < Laurenceb> sorry I need to scrollback

2022-01-13T16:15:46 < catphish> i definitely wouldn't use an undefined return code
2022-01-13T16:16:21 < catphish> relying on undefined OS behaviour is not the best idea
2022-01-13T16:16:37 < catphish> of course, one could use the 7 available bits to create a signed number
2022-01-13T16:17:02 < catphish> mawk: what's the point of WEXITSTATUS? when you already have the number?
2022-01-13T16:17:10 < mawk> you don't have the number already
2022-01-13T16:17:16 < mawk> the return status of pclose() isn't the exit code directly
2022-01-13T16:17:26 < mawk> it's some opaque value that needs to be manipulated with the macros like WEXITSTATUS
2022-01-13T16:17:36 < catphish> pclose():  on  success,  returns  the  exit  status  of the command
2022-01-13T16:17:37 < mawk> it's the &status argument in wait(2)
2022-01-13T16:17:40 < mawk> yeah but that doc is wrong
2022-01-13T16:17:43 < catphish> oh
2022-01-13T16:17:51 < mawk> for some reason
2022-01-13T16:18:14 < catphish> well that makes sense then, i've seen WEXITSTATUS in examples, but the manual seemed to contradict, so i was confused
2022-01-13T16:18:19 < mawk> I looked in the glibc code directly and ultimately the return of pclose() is the int *wstatus argument of waitpid(2)
2022-01-13T16:25:09 < mawk> here's a full example of eventfd Laurenceb : the parent https://paste.serveur.io/AdU2dtel.c and the child https://paste.serveur.io/ubwsVE9j.c
2022-01-13T16:25:41 < Laurenceb> thanks
2022-01-13T16:25:42 < mawk> instead of passing the eventfd number as argument you can also force it to be 9 for instance, 
2022-01-13T16:25:48 < mawk> to make things easier depending on what you do
2022-01-13T16:25:55 < mawk> anything between 3 and 9 included could work

2022-01-13T16:31:21 < ventYl_> HAL provides higher level of abstraction, carries a lot more garbage and limits you on corner case uses (not as much of control of peripheral as with ll)
2022-01-13T16:32:17 < riki> ok, is HAL something like CMSIS drivers (in terms of abstraction, I mean)
2022-01-13T16:32:26 < riki> ?

2022-01-13T16:44:44 < mawk> not really
2022-01-13T16:44:52 < mawk> hal is for peripherals
2022-01-13T16:45:14 < mawk> I guess cmsis is like ll for control of the arm registers
2022-01-13T16:45:28 < mawk> hal is higher levels
2022-01-13T16:49:06 < riki> ok, thanks
2022-01-13T16:59:35 < mawk> riki: ll is just giving a name to registers, hiding them behind a simple function
2022-01-13T17:00:05 < mawk> but hal controls peripherals as a whole, handles low level plumbing like IRQs or DMA, etc
2022-01-13T17:00:12 < mawk> don't listen to them and just use HAL

2022-01-13T17:23:28 < jpa-> for some reason after it does  CoreDebug->DEMCR |=  CoreDebug_DEMCR_MON_STEP;   everything starts behaving weird
2022-01-13T17:25:17 < mawk> are you supposed to do that from code jpa- ?
2022-01-13T17:25:30 < mawk> shouldn't you do that kind of stuff through swd instead
2022-01-13T17:26:23 < jpa-> this is   https://github.com/adamgreen/mri   so software monitor for debugging through serial port
2022-01-13T17:26:36 < jpa-> because owon engineers decided to use SWD pins for keyboard
2022-01-13T17:26:55 < mawk> lol
2022-01-13T17:27:31 < mawk> and do you get yourself into DebugMonitor exception?
2022-01-13T17:27:33 < mawk> or does it fail before
2022-01-13T17:28:21 < riki> karlp: do you mean Bluetooth host?
2022-01-13T17:28:45 < jpa-> oooh crap, it is doing that STEP stuff from USART0_IRQHandler
2022-01-13T17:28:52 < jpa-> and then it ends up trying to single-step itself
2022-01-13T17:28:58 < jpa-> that's not gonna end well
2022-01-13T17:29:50 < jpa-> whoever it was that wrote the platform glue code this morning has messed things up..
2022-01-13T17:30:09 < mawk> isn't it what the doc say ? "The effect of setting this bit to 1 is unpredictable if the code being debugged is executing at an execution priority that is lower than the priority of the DebugMonitor exception"
2022-01-13T17:33:08 < jpa-> yes..
2022-01-13T17:33:16 < jpa-> i had two lines in wrong order
2022-01-13T17:33:51 < jpa-> i had   NVIC_SetPriority(USART0_IRQn, 0);   mriCortexMInit(NULL, 0, LAST_IRQn);    and the mriCortexMInit sets all interrupts to lower priority

2022-01-13T18:13:29 < BrainDamage> when you have 2fa it relaxes the requirements on login
2022-01-13T18:13:33 < fenugrec> yes
2022-01-13T18:14:01 < BrainDamage> and I say it's a travesty because normally you store it in the same place of the pw

2022-01-13T18:41:39 < kakium69> while I change timing belt
2022-01-13T18:44:02 < fenugrec> they can wear out... are you really at  500 Mm and still running the orig pulley
2022-01-13T18:44:45 < kakium69> yes
2022-01-13T18:45:15 < kakium69> how about camshaft one that is bigger and stuff?
2022-01-13T18:46:34 < kakium69> while I'm at it I just might replace crankshaft axle seal
2022-01-13T18:46:44 < fenugrec> that doesn't sound like a weekend project
2022-01-13T18:46:53 < fenugrec> why not open it up and look what it needs
2022-01-13T18:46:53 < kakium69> it could be
2022-01-13T18:47:45 < kakium69> I'm replacing head gasket but also timing belt while I'm at it
2022-01-13T18:48:24 < kakium69> fenugrec: well that is not weekend project if you open it up and then start ordering parts
2022-01-13T18:49:49 < fenugrec> ofc. but you need to be sure you have absolutely all parts before you open it up then P )
2022-01-13T18:50:06 < fenugrec> maybe your belt looks like this one https://www.yotatech.com/forums/attachments/f116/163281d1501528238-what-does-worn-timing-belt-look-like-3vze-4d91621aa88cb98cebeac3f04cc41c85_zpsa0ec0fef.jpg
2022-01-13T18:50:17 < kakium69> it doesn't
2022-01-13T18:50:31 < kakium69> it has just 80000km on it
2022-01-13T18:51:17 < kakium69> I looked at it and it looked like rather new
2022-01-13T18:51:29 < fenugrec> how
2022-01-13T18:51:38 < fenugrec> inspection hole or took some covers off ?
2022-01-13T18:51:46 < kakium69> just belt cover off
2022-01-13T18:51:57 < fenugrec> ah so you could see the pulleys then
2022-01-13T18:52:03 < kakium69> top one
2022-01-13T18:52:22 < kakium69> and tension wheels etc. but not bottom one
2022-01-13T18:52:47 < fenugrec> if belt is narrower than pulley, you can guess the amount of wear , both ends of the teeth will have mostly their original shape
2022-01-13T18:52:51 < fenugrec> ah i see
2022-01-13T18:53:01 < englishman> yes kaks the idler wears out
2022-01-13T18:53:13 < englishman> it comes in the kit
2022-01-13T18:53:13 < fenugrec> well bigger pulley should have less tooth loading, ofc
2022-01-13T18:53:24 < kakium69> idler = tensioner?
2022-01-13T18:53:30 < englishman> not always
2022-01-13T18:53:35 < fenugrec> sometimes
2022-01-13T18:53:37 < fenugrec> heh
2022-01-13T18:53:53 < kakium69> it's rather big the top one and it's rather small the bottom one
2022-01-13T18:53:59 < englishman> tensioner usually comes with its pulley and the tensioner assembly. Replace that too
2022-01-13T18:54:14 < kakium69> yes I have made that mistake before englishman
2022-01-13T18:54:27 < kakium69> tensioner was so dead it didn't tension new belt
2022-01-13T18:54:31 < englishman> why not just get a new car
2022-01-13T18:54:45 < fenugrec> or younger engine
2022-01-13T18:54:48 < englishman> you can get a mitsubishi mirage for like $6k
2022-01-13T18:55:05 < fenugrec> mine's probably a ticking bomb too @ 330k ... ugh
2022-01-13T18:55:27 < englishman> vw?
2022-01-13T18:55:32 < fenugrec> nissan
2022-01-13T18:55:48 < englishman> anyway cars here are pretty much dead after 10y
2022-01-13T18:56:00 < fenugrec> I know, I'm doing pretty well for a '05
2022-01-13T18:56:10 < kakium69> englishman: nobody should buy mirage for any sum of money
2022-01-13T18:56:21 < englishman> had to trash wifeishmans 04 prius last year. Sad
2022-01-13T18:56:38 < kakium69> wasn't that like some worst car of the year that mirage thing
2022-01-13T18:56:54 < englishman> yes that’s why it’s $6k new
2022-01-13T18:56:57 < englishman> With warranty
2022-01-13T18:57:01 < kakium69> 6k new :o
2022-01-13T18:57:21 < fenugrec> wut
2022-01-13T18:57:35 < fenugrec> "starting at 14600$"
2022-01-13T18:57:46 < englishman> Yeah fen i saw them at $9k beaverbux before the shit started
2022-01-13T18:57:52 < fenugrec> where do you see 6k
2022-01-13T18:57:54 < fenugrec> hum
2022-01-13T18:57:56 < englishman> Canadian idiot tax there
2022-01-13T18:57:58 < englishman> 6k usd

2022-01-13T18:58:29 < kakium69> cars are so cheap in americas that I should buy one from there and get it shipped here
2022-01-13T18:58:38 < kakium69> save like >50%
2022-01-13T18:58:47 < kakium69> 8P
2022-01-13T18:59:14 <@karlp> kakium69: I tried that once, import duties very quckly make that not as easy as you think :)
2022-01-13T18:59:23 < fenugrec> pff you get all the nice diesel models in EU, we only get Murican V6+ diesels (and vw)
2022-01-13T18:59:42 <@karlp> I tried to import my own subaru when I moved from .us to .is,
2022-01-13T19:00:00 <@karlp> I ended up selling it for ~12k or so, and .is wanted about 14k in import duties on it..
2022-01-13T19:00:23 < kakium69> what do you have now?
2022-01-13T19:00:44 < Steffann> Here zhe fog is gone mawk

2022-01-13T19:36:03 < kakium69> no
2022-01-13T19:36:14 < kakium69> timing belt pulley that is under that

2022-01-13T19:59:56 < kakium69> it's not excessive amount
2022-01-13T20:00:14 < kakium69> simple prototype runs can get to thousands of those
2022-01-13T20:00:34 < kakium69> extended part catphish?
2022-01-13T20:08:18 < catphish> kakium69: no, basic part, they must use a LOT
2022-01-13T20:08:49 < kakium69> when I ordered I think 0603 caps or resistors were all extended

2022-01-13T22:57:11 < mawk> on the film
2022-01-13T22:57:30 < BrainDamage> i know, but still, it's random, and non predicible
2022-01-13T22:57:48 < BrainDamage> and it interacts with another random thing which are incident photons
2022-01-13T22:57:58 < BrainDamage> so it's noise
2022-01-13T23:00:03 < BrainDamage> and it's not like you can measure it beforehand and compensate, because guess what you'd have to use to measure? photons

2022-01-13T23:52:49 < catphish> personally, i would consider using them for a large run if they delivered the prototype correctly, seems like common sense to do so
2022-01-13T23:54:06 < catphish> the only downside is when using unusual parts, you have to choose them based on their available parts, but i'm somewhat accustomed to this process now
2022-01-13T23:55:03 < catphish> like, designing a SMPS took forever, because i had to go through their available controllers to see what was suitable, rather than choosing the best part from (for example) a TI parts list
2022-01-13T23:55:30 < catphish> but i'm more than happy with JLC's execution
2022-01-13T23:56:12 < catphish> fingers crossed my "v3" BMS boards are correct :)

2022-01-14T00:02:32 < kakium69> did you sleep on it?
2022-01-14T00:03:07 < kakium69> or placed order immediatelly?
2022-01-14T00:03:42 < kakium69> altough revisioning and little updates are usually rather trivial
2022-01-14T00:06:14 < catphish> kakium69: i finished the design yesterday, checked it twice more today before ordering :)
2022-01-14T00:06:30 < kakium69> you are learning
2022-01-14T00:07:16 < catphish> i posted here last night - i assume at this point everyone was bored enough of me not to check it for me again!
2022-01-14T00:07:52 < catphish> but mostly just swapping in a (now tested) zener setup
2022-01-14T00:08:04 < catphish> so it was fairly trivial
2022-01-14T00:10:07 < fenugrec> DK pcbs works out to about 6$/sqin for small stuff

2022-01-14T00:18:00 < catphish> the main cost in my builds by a large margin is ICs
2022-01-14T00:18:36 < fenugrec> yea bms ICs are insane. ltc6813 was > 30$
2022-01-14T00:18:52 < catphish> in this order I have RS485, CAN, and SMPS ICs, they make the cost of the boards and passives insignificant
2022-01-14T00:21:57 < catphish> i should start compiling a BOM for my car, to work out how much it's costing, or last how much it *would* be costing if i got everything right first time

2022-01-14T15:11:10 < Xogium> is it bad if the metal contact under the side of my breadboard are bent ? I grabbed it and they bent just like that, with almost no resistance
2022-01-14T15:11:21 < Xogium> almost like they were designed to bend that way if you wished
2022-01-14T15:14:46 < jpa-> i'm not sure what metal contacts they would be
2022-01-14T15:15:16 < PaulFertser> Xogium: try to show a photo
2022-01-14T15:15:23 < Xogium> jpa-: this breadboard
2022-01-14T15:15:26 < Xogium> https://www.adafruit.com/product/2463
2022-01-14T15:15:39 < Xogium> it doesn't have the sticky stuff to hide the rows
2022-01-14T15:17:40 < BrainDamage> that's megastupid
2022-01-14T15:17:45 < Xogium> my gues is it was deliberately done that way, no sticky thing to the under side so you can figure out the orientation, which are rows and which are columns… Otherwise 4x4 is a bit difficult
2022-01-14T15:18:15 < jpa-> Xogium: the metal contacts there seem like they could be used for soldering something, but other than that it probably doesn't matter which way they are pointing
2022-01-14T15:18:33 < Xogium> BrainDamage: what is ?
2022-01-14T15:19:11 < jpa-> apparently that breadboard is meant for soldering on a PCB, to provide some prototyping space
2022-01-14T15:19:18 < jpa-> so the pins are for that
2022-01-14T15:19:23 < Xogium> oh
2022-01-14T15:19:33 < Xogium> really ? How did you figure that out ?
2022-01-14T15:21:21 < Xogium> I read through the datasheet and the desc on adafruit but didn't figure it was the original intended use
2022-01-14T15:21:25 < jpa-> "There are four white posts on the bottom for PCB positioning" is a clue, and also how it looks
2022-01-14T15:21:33 < Xogium> oh
2022-01-14T15:21:54 < Xogium> I didn't know that is what it meant
2022-01-14T15:22:02 < jpa-> could be fun to include one of those on a dev board :)
2022-01-14T15:23:21 < Xogium> so… wait, if that's not to indicate the rows as I thought it did
2022-01-14T15:23:35 < Xogium> then how in the word do you determine rows/columns ?
2022-01-14T15:23:40 < Xogium> *world even
2022-01-14T15:24:26 < ventYl_> Xogium: ohmmeter?
2022-01-14T15:25:05 < Xogium> dunno… I guess ? I don't have one
2022-01-14T15:25:24 < jpa-> i guess it is a side benefit to make the direction clear
2022-01-14T15:25:51 < jpa-> if they had had 5 cents more money they could have printed lines on the top
2022-01-14T15:27:21 < Xogium> yecch yeah… Meh. I'm not going to risk it
2022-01-14T15:27:40 < Xogium> I'll keep my big badass breadboard that is like probably 30 times this size
2022-01-14T15:29:33 < Xogium> though… logically if you want to solder to a pcb, I suppose it wouldn't make sense to solder the same row
2022-01-14T15:29:48 < Xogium> I mean, to only solder in one column

2022-01-14T15:46:35 < Xogium> jpa-: seems like the contact are one per row, right ? That would seem to make way more sense to me, than if it was the same column
2022-01-14T15:47:49 < jpa-> Xogium: yes
2022-01-14T15:48:13 < jpa-> Xogium: the breadboard is longer in one direction, the holes along the long side are connected together and there is a pin at the end of each row
2022-01-14T15:48:57 < Xogium> so ok I can base myself on that, good

2022-01-14T16:50:04 < Xogium> a tester enters in a bar. He orders 0 beer, then one, then 2, then 5, then 9999. He walks in the bar, then runs, then jumps, then sit on the floor, on a chair, leaves, then reenters at a running pass. He then confirm everything is okay.

2022-01-14T16:54:00 < Laurenceb> its breaking in some cases for me due to rounding errors when calculating the step sizes

2022-01-14T16:59:09 < Laurenceb> something like that?
2022-01-14T17:00:25 < BrainDamage> i'm just guessing because i cannot see the rest of the code, but yes
2022-01-14T17:01:33 < BrainDamage> it doesn't even matter if you don't pick middle, it just converges slower
2022-01-14T17:02:28 < Laurenceb> atm I have 1000000 samples and can never get to sample 29, it converges on sample 27 due to rounding errors
2022-01-14T17:03:48 < ventYl_> what rounding errors? during comparison of values of samples, or sample index calculation?
2022-01-14T17:04:57 < Laurenceb> sample index calculations
2022-01-14T17:05:04 < Laurenceb> as the step size is always rounded down
2022-01-14T17:05:15 < ventYl_> well, that doesn't matter
2022-01-14T17:07:06 < Laurenceb> it does, try to get to 29 when starting from 1000000
2022-01-14T17:07:21 < Laurenceb> you will get stuck at 27 if you try it on paper
2022-01-14T17:07:50 < ventYl_> no, it doesn't. if you round down, at certain point during iteration, you will select subinterval right of pivot
2022-01-14T17:08:17 < ventYl_> exact position of pivot within interval doesn't impact success of search, it only impacts time
2022-01-14T17:08:51 < ventYl_> you have some other problem in your algorithm, looks like you have off-by-one problem somewhere and you ignore certain values or calculate interval boundaries incorrectly
2022-01-14T17:08:57 <@karlp> lolrence probably didn't have some spaces somewhere, and the code was doing something differeny.
2022-01-14T17:09:56 < ventYl_> or maybe you use > and < operator exclusively, where you should use >= and <
2022-01-14T17:13:22 < mawk> try what on paper
2022-01-14T17:17:42 <@karlp> jadew`: one for you https://www.seeedstudio.com/JNCRADIO-VNA-3G-p-5280.html?utm_source=mailchimp&utm_medium=edm&utm_campaign=bazaar_0113&ct=t()&mc_cid=f763853981&mc_eid=84f53cd027

2022-01-14T17:18:03 < Laurenceb> mawk: dividing down 1000000 with integer division
2022-01-14T17:18:18 < mawk> sure it works
2022-01-14T17:18:29 < mawk> you get something like [15; 30] interval at some point
2022-01-14T17:18:41 < mawk> split in half, take either the left one, or the right one
2022-01-14T17:18:43 < mawk> then continue
2022-01-14T17:18:50 < mawk> at which point exactly would you exclude the value "29" ?
2022-01-14T17:19:03 < Laurenceb> ah ok thats the way to do it then
2022-01-14T17:19:10 < mawk> yeah
2022-01-14T17:19:11 < Laurenceb> I was just setting a step size
2022-01-14T17:22:03 < mawk> it wouldn't be binary search otherwise
2022-01-14T17:22:18 < mawk> what are you binary searching?
2022-01-14T17:32:50 < Steffanx> Good humor. Explains why he fails to find it.
2022-01-14T17:37:55 < bitmask> ello
2022-01-14T17:39:27 < PaulFertser> What is this unpopulated zone on the bottom right in this wifi ap+router: https://wusiyu.me/wp-content/uploads/2017/04/psb-1.jpg ?
2022-01-14T17:45:42 < bitmask> special feature for a more expensive model :)
2022-01-14T17:46:43 < PaulFertser> bitmask: yes, but there seem to be enough clues to tell what that feature is. Looks like some low speed wireless something.
2022-01-14T17:47:25 < bitmask> yea i dunno, can you look up similar models of the router and see what they offer that looks like it fits?
2022-01-14T17:47:34 < PaulFertser> I tried but failed so far
2022-01-14T17:47:37 < bitmask> ahh
2022-01-14T17:47:49 < PaulFertser> It's a netgear r6220
2022-01-14T17:48:53 < mawk> unpopulated stuff on the left of the pic looks more interesting PaulFertser 
2022-01-14T17:49:36 < mawk> something small like this on the bottom right I wouldn't know what it is, but I'm pretty sure it wouldn't be extra flash or dram
2022-01-14T17:49:57 < mawk> where do the traces lead
2022-01-14T17:52:55 < ventYl_> Laurenceb: oh, so you tried to implement retardsearch and failed? retardsearch is an alias for whatever result of someone's work on improvement of binarysearch. similarly to retardsort being an alias for whichever "improvement" of quicksort
2022-01-14T17:54:37 < PaulFertser> mawk: on the left it's just a pcie connector but mt7612 5 GHz wireless is attached there instead: https://openwrt.org/_media/media/netgear/netgear_r6220_pcb.jpg
2022-01-14T17:57:07 < PaulFertser> It's unclear where the traces lead, U1208 is outside of the isolated part.
2022-01-14T17:57:20 < mawk> yeah I remarked the cutout thing

2022-01-14T20:21:51 < Xogium> oh, this looks interesting. Friend of mine just found out about some jumper wires that *could* potentially get rid of my need to solder
2022-01-14T20:22:51 < Xogium> the jumper wires are apparently made with some similar tech to press fit where inserting them into the holes on a pcb causes them to expand inside and holding by friction
2022-01-14T20:23:46 < Xogium> sure won't beat having actual headers but… if you don't have them handy
2022-01-14T20:25:41 < PaulFertser> Xogium: yes, there exist pin headers like that, with a springy end. I do not recommend using those, why add instability and uncertainty if you can just have your friend solder normal headers.

2022-01-14T20:28:13 < fenugrec> with the number of how-to videos on YT, anything but success is impossible
2022-01-14T20:28:47 < Xogium> that's kinda the aspect that worries me, so many videos…
2022-01-14T20:29:01 < Xogium> and nothing telling for sure if they show sane things or not
2022-01-14T20:29:04 < PaulFertser> There're some special people which function normally but somehow have issues doing specific jobs that are trivial for the majority. But that's unlikely.
2022-01-14T20:29:49 < PaulFertser> Xogium: get him here and we'll discuss specifics and can tell by photos if he's doing all right.
2022-01-14T20:30:07 < mawk> do you take pictures and use AI audiodescription to look at them Xogium ?

2022-01-14T21:46:24 <@karlp> PaulFertser: I'd say it's definitely another radio?
2022-01-14T21:46:32 <@karlp> possibly a 6ghz or something?
2022-01-14T21:48:43 < PaulFertser> karlp: looks like another radio but most probably not wifi. The (I) zone looks like some elaborate RF matching something circuit but is antenna soldered to U29? And what's that other missing chip on the left and why the ground is separate? 
2022-01-14T21:49:16 <@karlp> maybe another power supply for it?
2022-01-14T21:49:36 <@karlp> or rf amp
2022-01-14T21:50:04 <@karlp> yeah, u29 is the antenna connector, same style as elsewhere ont he board
2022-01-14T21:50:50 <@karlp> I think "short2" and "short3" are interesting as well :)
2022-01-14T21:52:00 <@karlp> hrm, no u54 is probably the power supply,  u1208, no idea, 
2022-01-14T21:52:16 <@karlp> but yeah, best path would be looking for other product descriptions I guess.
2022-01-14T21:52:28 <@karlp> wigig or something regional would be my guess
2022-01-14T21:52:46 <@karlp> possibly even something for an ISP's value add of some sort?
2022-01-14T21:53:17 <@karlp> bought an so8 test clip like this: https://www.aliexpress.com/item/32826777114.html
2022-01-14T21:53:46 < PaulFertser> The idea is that it's unlikely high-speed because apparently PCIe isn't routed there.
2022-01-14T21:53:55 <@karlp> was not expecting that the leads on the end were on a tight pitch, I expected to be able to use common 2.54mm jumper leads on it but no...
2022-01-14T21:54:05 <@karlp> well, "high speed" is only wifi6 and up.
2022-01-14T21:54:11 <@karlp> wifi5 is fine over usb2...

2022-01-15T04:28:46 < fenugrec> well one cycle of eg squarewave has 2 edges, so 250MHz
2022-01-15T04:29:26 < fenugrec> but I wouldn't say "usable at 250MHz" except for special cases. Like this, driving a square edge into a terminated 50ohm line
2022-01-15T04:30:16 < fenugrec> Tpd and stuff is still of the order of 3-5 ns so any combinatorial logic is going to be... interesting

2022-01-15T04:32:47 < System_Error> Er? if edge below 1ns it means 2 would be less than 2 thus over 500?
2022-01-15T04:34:23 < fenugrec> I don't think you'd get a full output signal if driven at 500M, but I haven't tried
2022-01-15T04:37:34 < fenugrec> but lol yes 1ns x2 would be 500mhz

2022-01-15T20:46:13 < bitmask> media? over coaxial
2022-01-15T20:46:51 < bitmask> my isp uses moca for cable boxes and stuff to provide service throughout the house over the coax lines, including internet. you just need a moca adapter to plut into the coax and then you get an ethernet port on the other side
2022-01-15T20:47:30 < bitmask> so instead of having a mesh network i just have a router downstairs that I cant get good service from, and a router in my room for upstairs thats connected to the adapter 
2022-01-15T20:47:37 < bitmask> full speed internet
2022-01-15T20:48:36 < bitmask> but moca can be a pain because you need like filters and coax cant be split too much or the signal loss causes problems, so I'm not sure exactly whats happening but i know rebooting the adapter works
2022-01-15T20:48:41 < PaulFertser> Why do they prefer coaxial to fibre?
2022-01-15T20:48:54 < bitmask> who has fiber in their house?

2022-01-15T20:49:30 < PaulFertser> bitmask: so why is providing coax cheaper than providing fibre?
2022-01-15T20:49:54 < bitmask> i dont know? coax has been around forever
2022-01-15T20:50:04 < bitmask> are you saying your house has fiber?
2022-01-15T20:50:11 < bitmask> and thats standard wherever you are?
2022-01-15T20:50:37 < PaulFertser> I live in a multi-apartment building and I get 1000BASE-T to apartment. I guess they have a fibre link to the building.
2022-01-15T20:50:58 < bitmask> yes but what is in the apartment building
2022-01-15T20:51:03 < PaulFertser> Also, I know many people get GPON right to their apartments.
2022-01-15T20:51:30 < PaulFertser> In the building it's the usual 1000BASE-T
2022-01-15T20:51:46 < bitmask> what about tv?
2022-01-15T20:52:11 < PaulFertser> UDP multicast I think
2022-01-15T20:52:23 < bitmask> well we dont do that
2022-01-15T20:52:38 < PaulFertser> Why not?
2022-01-15T20:53:27 < bitmask> because coax has been around forever and maybe its different for new homes but most people arent going to pay to upgrade to that for minimal benefit
2022-01-15T20:53:35 < drzacek> hello there
2022-01-15T20:53:51 < PaulFertser> Hm, you can use same old coax for high-speed Internet?
2022-01-15T20:54:01 < bitmask> yes
2022-01-15T20:54:06 < PaulFertser> How fast is it?
2022-01-15T20:54:09 < drzacek> noob question (again): which document is the one that tells you about the pin connections you need to get it working (the reset, boot pins, crystals etc)?
2022-01-15T20:54:23 < PaulFertser> drzacek: datasheet + family reference manual
2022-01-15T20:54:41 < PaulFertser> drzacek: nucleo board schematics
2022-01-15T20:54:58 < bitmask> just did a speed test, 460mbit down
2022-01-15T20:55:00 < drzacek> thx
2022-01-15T20:55:11 < drzacek> unfortunately the nucleo board went "no hse" way
2022-01-15T20:55:13 < PaulFertser> bitmask: not bad for old silly cable
2022-01-15T20:55:25 < PaulFertser> drzacek: see the datasheet then.
2022-01-15T20:55:46 < bitmask> its probably capped by the cable company, i dont know what the family pays for
2022-01-15T20:55:47 < PaulFertser> drzacek: plus there an application note on calculating the right capacitors and choosing the right crystals.
2022-01-15T20:55:47 < drzacek> k
2022-01-15T20:56:00 < bitmask> probably 500
2022-01-15T20:56:01 < drzacek> havent found anything in ref manual, nor any application note
2022-01-15T20:56:23 < drzacek> yeah the hardware design guide something something oscilators. hard af to understand
2022-01-15T20:57:26 < bitmask> its fiber to the house so a little bit of copper shouldnt cause too many probs
2022-01-15T20:58:29 < PaulFertser> bitmask: here people were mostly using yagi or log-periodic antennas in houses to get regular analog TV. Plus sat dishes if they wanted to. Now it's all DVB-T2 for the masses + IPTV if you are using wired Ethernet. And some still use sats to watch all that bullshit too.
2022-01-15T20:58:50 < PaulFertser> drzacek: what exactly is unclear?
2022-01-15T20:59:12 < PaulFertser> bitmask: fiber to the house and then coax?!
2022-01-15T20:59:21 < bitmask> of course
2022-01-15T20:59:47 < PaulFertser> But why not just ethernet and no coax inside the house?
2022-01-15T21:00:20 < drzacek> PaulFertser, I'm wondering about the boot1 pin (Cant find it actually). got the vcc/vss/vssa pins done already, rest I take from cubemx. but the crystals? man I'm reading that thing 3rd time and still am as dumb as before
2022-01-15T21:00:38 < PaulFertser> drzacek: boot1 description should be in the datasheet.
2022-01-15T21:00:40 < bitmask> like I said, coax has been around forever, everyone has it in their house.  the fiber has to connect to the cable companies box outside so you can't just plug it into what you want 
2022-01-15T21:00:51 < drzacek> yep, looking for it now
2022-01-15T21:01:03 < PaulFertser> bitmask: coax _inside a house_ around forever? It's not like the house itself was around forever?
2022-01-15T21:01:08 < bitmask> you guys started with nothing so you have no old infrastructure to work with, so it makes sense to do it right for the current times, we have had this setup forever
2022-01-15T21:01:25 < bitmask> holy fuck, who takes that literally haha
2022-01-15T21:01:25 < PaulFertser> drzacek: AN2867
2022-01-15T21:02:16 < bitmask> the houses are built with coax from the start, like I said, it might be different now, i dont know, but thats how its been at least up until recently
2022-01-15T21:02:19 < PaulFertser> bitmask: you still need Ethernet inside the house, right? So why bother about using coax if you're wiring Ethernet everywhere anyway?
2022-01-15T21:03:01 < bitmask> because you dont need ethernet for tv, and these are cable companies that started with just tv
2022-01-15T21:03:40 < bitmask> internet came later in like late late 90s
2022-01-15T21:03:53 < drzacek> okay the boot pins are in ref manual
2022-01-15T21:04:13 < PaulFertser> I'm missing a lot of context apparently. I thought that when you move in a house you decide you need connectivity here and there and so you basically deploy ethernet to all rooms and you're the one to decide what to do, and it's not like the existing coax cabling helps anything at all?
2022-01-15T21:05:14 < PaulFertser> All TVs have ethernet and many have wifi and so you just connect them to your LAN and watch netflix or whatever?
2022-01-15T21:05:25 < bitmask> people with more money or just newer houses do have whole house ethernet but its not that common. since coax is in almost every home already most are willing to just use that, and as you can see from my speeds it really doesnt hurt much
2022-01-15T21:05:35 < bitmask> why pay to wire the whole house over again
2022-01-15T21:05:39 < bitmask> most users dont care at all
2022-01-15T21:05:57 < bitmask> i mean of course id rather ethernet but these moca adapters work fine for the most part 
2022-01-15T21:06:13 < PaulFertser> Except that you need to reboot them often log
2022-01-15T21:06:14 < PaulFertser> lol
2022-01-15T21:06:29 < drzacek> PaulFertser, correct. that's how it was here. we pointer finger where we want lan, and we paid for the installation
2022-01-15T21:06:31 < bitmask> well im sure its fixable
2022-01-15T21:06:52 < PaulFertser> How many meters of cat5 would you need to add to get rid of coax?
2022-01-15T21:06:57 < drzacek> what are moca adapters
2022-01-15T21:07:15 < drzacek> PaulFertser, I assume it's more about opening walls than about cable price
2022-01-15T21:07:33 < bitmask> either with a filter or something, and I'm using the moca network coming from the cable companies box which it probably wasn't designed for.  If i wanted to do it right, I'd get my own 'parent' moca router and id be fine
2022-01-15T21:07:37 < drzacek> bitmask, what about those powerline adapters, it transfers LAN over mains sockets
2022-01-15T21:07:43 < PaulFertser> drzacek: if a cable is present there then there already is a hole in the wall to pass the cable through.
2022-01-15T21:07:47 < bitmask> moca is so much better
2022-01-15T21:08:33 < drzacek> not sure what you mean. I have space in walls for cables, but doing anything more complex that drilling to the other side of the wall would mean opening a lot of walls and ceilings
2022-01-15T21:08:39 < PaulFertser> drzacek: and it's not like drilling another hole costs anything?
2022-01-15T21:08:59 < bitmask> you are being ridiculous i hope you are aware.  why pay to rewire your house when its not necessary (cost is wire + mainly labor). most people don't even need moca adapters so its a non issue. 
2022-01-15T21:09:03 < drzacek> as I said, depends on the wall
2022-01-15T21:09:50 < drzacek> bitmask, if it's an old house, you might have better chances putting new cables in the floor
2022-01-15T21:09:51 < bitmask> its an expense that is completely unnecessary
2022-01-15T21:10:04 < PaulFertser> drzacek: cables do not need to be _in_ walls, you just glue a plastic cable channel to a wall and that's it, basically free.
2022-01-15T21:10:17 < drzacek> or, if it's old high ceiling house, pulling them on ceiling and hanging those styrofoam plates to fake new ceiling a bit lower than original
2022-01-15T21:10:23 < bitmask> if you have wiring issues then sure, upgrade to ethernet, but if your coax is fine there is no reason to
2022-01-15T21:10:27 < drzacek> PaulFertser, I dare you to say that to my wife
2022-01-15T21:10:41 < bitmask> PaulFertser jesus, you are fighting just to fight, im going back to coding
2022-01-15T21:10:54 < drzacek> no no, wait, I might need more help!
2022-01-15T21:11:09 < bitmask> PaulFertser is right about everything so he can help you
2022-01-15T21:11:17 < PaulFertser> drzacek: I do not understand why people spare all that effort trying to hide cabling, it's clearly counter-productive.
2022-01-15T21:12:14 < drzacek> it looks clean
2022-01-15T21:12:39 < drzacek> same reason why people clean their houses I guess
2022-01-15T21:12:50 < PaulFertser> Your living place is not an art gallery.
2022-01-15T21:13:16 < bitmask> your place must look like shit
2022-01-15T21:13:22 < drzacek> well I had a chance of doing everything the way I wanted, so I don't have problem. I got lan and 230V everywhere I need (almost :( )
2022-01-15T21:13:35 < drzacek> and I do enjoy having all cables hidden in wall
2022-01-15T21:13:51 < bitmask> as any normal person would
2022-01-15T21:13:51 < PaulFertser> bitmask: that's possibly the word, yes.
2022-01-15T21:14:14 < bitmask> i cant tell if you are just trolling or not
2022-01-15T21:14:23 < PaulFertser> I'm not, I really am like that.
2022-01-15T21:14:47 < drzacek> please don;t be mad
2022-01-15T21:14:49 < PaulFertser> I have a motor bike engine semi-dissambled 1 m away from the kitchen.
2022-01-15T21:15:13 < drzacek> I'm not judging, just wondering - do you live alone? or do you live with a woman? wife, girlfriend, mom, no matter
2022-01-15T21:15:21 < PaulFertser> wif
2022-01-15T21:15:25 < drzacek> okaaaay
2022-01-15T21:15:34 < bitmask> usually people use cable channels and stuff because its cheaper than having someone come in and install the wires, not because they dont care how it looks
2022-01-15T21:16:30 < drzacek> well, the price is a major role, so hiding it in the white plastic tunel is one way to deal with it. If your smart about it it can be okay-ish

2022-01-15T21:27:29 < PaulFertser> But even iran doesn't invade lately
2022-01-15T21:27:42 < mawk> often there's none drzacek 
2022-01-15T21:27:46 < mawk> depending on the package
2022-01-15T21:27:47 < PaulFertser> drzacek: if it's not in the datasheet then it's probably in "option bytes"
2022-01-15T21:27:52 < mawk> yeah
2022-01-15T21:27:53 < drzacek> okay
2022-01-15T21:27:58 < drzacek> and those are set how
2022-01-15T21:28:02 < mawk> in eeprom
2022-01-15T21:28:03 < PaulFertser> Via SWD
2022-01-15T21:28:14 < mawk> option byte is a patch of eeprom
2022-01-15T21:28:16 < PaulFertser> By special target-specific commands, OpenOCD has those.
2022-01-15T21:28:19 < mawk> but you can set it via swd yeah
2022-01-15T21:28:20 < drzacek> okay, so no need to fiddle with them in hardware
2022-01-15T21:28:24 < mawk> no
2022-01-15T21:30:21 < jpa-> BOOT1 is often also shared with some GPIO pin
2022-01-15T21:30:32 < drzacek> I know stm32f103 had it 
2022-01-15T21:30:45 < drzacek> the bluepill board had two jumpers for them
2022-01-15T21:30:49 < PaulFertser> Right
2022-01-15T21:30:57 < drzacek> but cant see anything on stm32l431 64pin 
2022-01-15T21:30:57 < Xogium> hmm so… can someone explain to me what wire wrapping is ? I've heard it can sort of be the next step after breadboarding, if you want a more 'permanent' prototype
2022-01-15T21:31:07 < Xogium> while still avoiding soldering
2022-01-15T21:31:16 < drzacek> a wire is wrapped around a pin
2022-01-15T21:31:21 < drzacek> usually by special tool
2022-01-15T21:31:29 < drzacek> and require special pins?
2022-01-15T21:31:51 < drzacek> and last time anybody used that was in the 80s
2022-01-15T21:33:08 < jpa-> drzacek: the STM32L431 datasheet says: "BOOT1 option bit"   not a pin
2022-01-15T21:33:11 < PaulFertser> Xogium: yes, it's an old school technology where special posts were used and the wire was essentially welded to it by pressure of a special tool. Very reliably.
2022-01-15T21:33:39 < Xogium> hmm
2022-01-15T21:33:41 < drzacek> https://youtu.be/lG5oKLrG7R0?t=115
2022-01-15T21:34:10 < jpa-> Xogium: wire wrapping is pretty rarely used nowadays, but i guess it might suit you as there it no need to use heat
2022-01-15T21:34:18 < drzacek> soldering such thing shouldn't be hard tho
2022-01-15T21:34:21 < Xogium> so I couldn't really use this to make my prototype things more permanent nowadays ?
2022-01-15T21:34:32 < Xogium> oh… still workable ?
2022-01-15T21:34:45 < mawk> I don't think giving a video is useful drzacek lol
2022-01-15T21:34:53 < jpa-> if you prototype with breakout boards or similar, you can use it; it just needs square pins
2022-01-15T21:34:56 < PaulFertser> drzacek: yes, but that's not a special post so it's probably not so good.
2022-01-15T21:35:04 < drzacek> yep
2022-01-15T21:35:14 < Xogium> I mean don't get me wrong, if my buddy could do that for me I'd say yes in an instant, but… I'm on my own 99.9% of the time so
2022-01-15T21:35:20 < PaulFertser> drzacek: Xogium needs something that doesn't require visual feedback
2022-01-15T21:35:25 < drzacek> ah
2022-01-15T21:35:53 < Xogium> soldering, I mean
2022-01-15T21:36:21 < Xogium> though that sort of might change with how sick I'm getting
2022-01-15T21:37:17 < drzacek> it might work for special headers then, but not sure about rest. If there are IC sockets with wirewrap pins, then maybe ?
2022-01-15T21:37:44 < drzacek> I can't imagine wire wrapping the atmega legs directly
2022-01-15T21:38:01 < Xogium> but… so these days, the next step after breadboarding is straight to blank proto board + soldering ? Usually, I mean

2022-01-15T21:39:10 < PaulFertser> Xogium: these days it's cheap to get PCB manufactured even just for prototyping.
2022-01-15T21:39:57 < Xogium> yeah… maybe I don't realize just how cheap
2022-01-15T21:42:13 < Xogium> but I found out I kind of like wiring things up, at least. I can do it if whatever I used is keyed in some way…
2022-01-15T21:42:28 < PaulFertser> 5 two-layer boards 100x100 mm is 2 USD + shipping on jlcpcb.
2022-01-15T21:43:03 < PaulFertser> But it's some special so going to be 4 normally.
2022-01-15T21:43:11 < Xogium> like this IR sensor I connected to my st dev kit, it has a bump on one side, probably where the receiver is. So if it's put on my breadboard with the bump facing away from me, pins are 3, 2, 1
2022-01-15T21:45:18 < Xogium> wow, that cheap ? I suppose this excludes assembling and it is just blank pcb ? But still
2022-01-15T21:45:36 < Xogium> I thought it was like over 100 lol

2022-01-15T21:52:25 < drzacek> if you use standard parts (from jlc), you can get it assemblied for cheap too. dont know the prices, but that's affordable too nowadays
2022-01-15T21:53:35 < PaulFertser> Yes, that's amazing how affordable that is, starts from seven bucks.
2022-01-15T21:55:25 < Xogium> if I didn't know better, I'd think that was a scam
2022-01-15T21:57:03 < kakium69> 7usd plus shipping 70dollards
2022-01-15T21:57:29 < Xogium> ah ah
2022-01-15T21:57:35 < PaulFertser> Setup fee: $7.00 , Stencil: $1.50 , SMT Assembly: $0.0015 per joint "When a part from the Extended Components Library is used, the operator needs to mount the feeders manually, which increases the labor cost, we charge $3 per extended component."
2022-01-15T21:57:38 < Xogium> so that's where the money goes
2022-01-15T21:57:50 < PaulFertser> kakium69: are you serious?
2022-01-15T21:58:23 < drzacek> no
2022-01-15T21:58:31 < drzacek> I mean, yes, they have the pricy shipping too
2022-01-15T21:58:41 < kakium69> notreally but shippings+duty easily exceeds the product price
2022-01-15T21:58:42 < drzacek> but if you can wait 1-2 weeks it is around 2-3 euros
2022-01-15T21:58:55 < zyp> kakium69, well, duh
2022-01-15T21:59:13 < zyp> my last jlcpcb order was $2 of product and $13.2 in shipping
2022-01-15T21:59:26 < jpa-> yeah, i've been using aisler more and more because the shipping + customs costs
2022-01-15T21:59:34 < zyp> but the one before that was $135.62 in product and $20.8 in shipping
2022-01-15T22:00:27 < drzacek> don't know how finite the price displayed during quotation is (I uploaded my gerber files, cost was 2 euro for boards, and just under 3 euro for shipping)
2022-01-15T22:00:43 < drzacek> but I didn't ordered it, boss took the project and ordered elsewhere
2022-01-15T22:00:53 < zyp> the $135 was $31 for pcb, half of that being ENIG, and $112 for assembly
2022-01-15T22:01:08 < drzacek> lots of extra parts?
2022-01-15T22:01:19 < drzacek> *extended?
2022-01-15T22:01:21 < zyp> of the assembly cost, the parts themselves cost $82, and the extended parts fee was $18
2022-01-15T22:01:33 < drzacek> okay
2022-01-15T22:02:31 < zyp> I don't really think jlcpcb shipping is all that awful, considering it's DHL so shit's fast
2022-01-15T22:02:52 < drzacek> good, good
2022-01-15T22:02:57 < drzacek> so about those crystals
2022-01-15T22:03:22 < drzacek> I think I have all my pins nicely connected, just need to add the gpio/spi/i2c later, once I get the project in cubemx done
2022-01-15T22:03:45 < drzacek> I need 32.768khz for lse, and two load capacitors for that
2022-01-15T22:04:22 < drzacek> but what for hse? I've seen all those devboards use 8mhz, but the allowed input frequency is huge, from 4 to 26mhz or something?
2022-01-15T22:04:31 < drzacek> is there are any reason everyone is using 8mhz?
2022-01-15T22:04:33 < zyp> 2-26 IIRC
2022-01-15T22:04:37 < zyp> nope
2022-01-15T22:04:42 < qyx> I am not
2022-01-15T22:04:43 < zyp> 12 is also common
2022-01-15T22:04:50 < qyx> I usually use 16 M
2022-01-15T22:04:52 < zyp> and I've used 25 before to save a BOM line
2022-01-15T22:05:08 < qyx> and yes, if there is ethernet on bnoard, I use 25
2022-01-15T22:05:12 < drzacek> 25 - not sure about this one, not so easily multiplied to 38
2022-01-15T22:05:19 < zyp> it doesn't matter
2022-01-15T22:05:20 < drzacek> for usb
2022-01-15T22:05:27 < PaulFertser> There's also a question whether you need USB or not.

2022-01-15T22:06:16 < drzacek> thats why I have ch340 for uart-usb
2022-01-15T22:06:23 < zyp> on the highend parts, you can use any integer MHz crystal within the valid range, because you generally start by dividing it to 1 MHz anyway, before feeding it to the PLL
2022-01-15T22:06:59 < drzacek> I just typed 25mhz as input on hse and made it calculate the 80mhz pll
2022-01-15T22:07:03 < zyp> and all the newer lowend parts have HSI48 and can do USB without an external crystal
2022-01-15T22:07:04 < drzacek> it worked, so I guess it's fine
2022-01-15T22:07:34 < drzacek> what I yet don't get are the load capacitors
2022-01-15T22:07:41 < zyp> for what I do, I'd generally either pick a highend part or a newer lowend part
2022-01-15T22:08:03 < zyp> load capacitor values are given by the crystal selection
2022-01-15T22:08:03 < drzacek> zyp, I picked what was available, got bunch of flash size and was still affordable

2022-01-15T22:13:26 < drzacek> I asked in ##electronics for some cheaty hacky and easy way for that
2022-01-15T22:13:36 < zyp> unless you know it exactly, you just guess at a reasonable number
2022-01-15T22:13:38 < drzacek> "no, you either care and understand it or don't, no middle ground"
2022-01-15T22:13:44 < drzacek> "no, no such thing"
2022-01-15T22:14:01 < jpa-> they clearly belonged in the second category of "not understanding"
2022-01-15T22:14:13 < drzacek> and bam! come to the right place, get values served on silver plate and the magical words every boy and girl wants to hear
2022-01-15T22:14:24 < drzacek> "just use ~this and don't stress about it"
2022-01-15T22:14:33 <@karlp> but really....
2022-01-15T22:14:39 <@karlp> I was serious when I said, do you even need HSE
2022-01-15T22:14:54 < drzacek> karlp, I probably don't, since the nucleo board doesn't have it
2022-01-15T22:15:02 < zyp> it does
2022-01-15T22:15:12 < zyp> nucleos usually get 8MHz from the stlink part
2022-01-15T22:15:13 < drzacek> on the stlink part
2022-01-15T22:15:19 < drzacek> ah, it's shared?
2022-01-15T22:15:22 < zyp> yes
2022-01-15T22:15:34 < drzacek> okay then
2022-01-15T22:15:38 <@karlp> but thgere is HSI,
2022-01-15T22:15:47 < zyp> XI on the actual part is hooked to MCO on the stlink
2022-01-15T22:15:47 <@karlp> which is more than sufficient for many uses, possibly including yours
2022-01-15T22:15:54 < drzacek> I thought it uses internal. It has empty pads with "8mhz" label near them
2022-01-15T22:16:02 < drzacek> karlp, it probably is
2022-01-15T22:16:03 < drzacek> BUT
2022-01-15T22:16:07 < drzacek> this is my learning project
2022-01-15T22:16:25 < zyp> I believe there's solder jumpers to pick HSE from either stlink or dedicated crystal
2022-01-15T22:16:28 < drzacek> and thought to myself "come, lets try this oscilator thingy, might learn something useful for future projects"
2022-01-15T22:16:34 < zyp> defaults to stlink, but you can switch if you want
2022-01-15T22:16:52 < drzacek> well the nucleo boards are designed to have the stlink part broken away
2022-01-15T22:17:10 < drzacek> you keep the nucleo and share the stlink with best friend
2022-01-15T22:17:21 < zyp> sure
2022-01-15T22:18:17 < drzacek> okay then, lemme find some crystal and calculate the value
2022-01-15T22:18:35 < drzacek> also, them electronics people said to just keep replacing the capacitors until the frequency is stable
2022-01-15T22:20:08 < zyp> stable?
2022-01-15T22:20:28 < zyp> it'll generally be stable whatever you pick, just wrong
2022-01-15T22:20:42 < drzacek> I keep using wrong words
2022-01-15T22:21:02 < zyp> and if your application doesn't care about a 0.1% error, you might not even notice
2022-01-15T22:21:20 < drzacek> is uart affected by that?
2022-01-15T22:21:29 < drzacek> was told spi is not, cause it has master clock line
2022-01-15T22:21:49 < zyp> uarts needs a somewhat accurate clock, but is way more lenient than that
2022-01-15T22:22:01 < drzacek> only thing that comes to my mind would be ubs
2022-01-15T22:22:04 < drzacek> *usb
2022-01-15T22:22:10 < zyp> perhaps, maybe not
2022-01-15T22:22:37 < zyp> when I ran into the issue, it was on a 2.4GHz radio chip
2022-01-15T22:23:05 < zyp> which means that the frequency is effectively multiplied to generate the 2.4GHz carrier
2022-01-15T22:23:25 < Xogium> is there something that exists that lets you put some dev board and some breadboard or something on them so they stay in place ? I mean, it's great to have my breadboard and my st dev kit hooked up but now I kind of have to be careful if I move them, hold bhe breadboard in one hand and the dev kit in the other
2022-01-15T22:23:32 < Xogium> maybe I don't explain well
2022-01-15T22:23:56 < fenugrec> tape to desk ?
2022-01-15T22:24:00 < zyp> in my case I weren't 0.1% off even, I were 0.025% off, which at 2.4GHz translates to 0.6 MHz
2022-01-15T22:24:23 < zyp> and with 1MHz channels, that caused my radios to have problems locking onto the right channel
2022-01-15T22:24:29 < drzacek> zyp, the solution would be to hook osciloscope to the oscilator and measure the frequency, and change the load capacitors?
2022-01-15T22:24:46 < zyp> oscilloscope isn't accurate enough
2022-01-15T22:24:53 < zyp> you need a spectrum analyzer or something
2022-01-15T22:24:59 < Xogium> fenugrec: hmm that's an idea. But I thought tape was possibly electrically conductive ?
2022-01-15T22:25:44 < fenugrec> unless you use alu or copper tape, you should be ok
2022-01-15T22:25:54 < zyp> I actually debugged a similar issue at work a few weeks ago, suspected the same problem, but spectrum analyzer showed the frequency was good
2022-01-15T22:26:08 <@karlp> MCO divided to a freq counter should be suficient too I'd suppose.
2022-01-15T22:26:08 < Xogium> I uh don't know actually which I have on hand
2022-01-15T22:26:30 < zyp> turned out problem was some bad power decoupling caps instead, so the radio didn't get stable enough power
2022-01-15T22:26:31 <@karlp> drzacek: basically, unless you're doing ethernet or usb, and want them to work across full temp ranges, or have other very specific timing requirements, you don't need HSE.
2022-01-15T22:27:12 < drzacek> ok
2022-01-15T22:27:20 < drzacek> what about the max CPU clock
2022-01-15T22:27:27 < drzacek> how definitive is the max value
2022-01-15T22:27:35 < zyp> you can overclock it
2022-01-15T22:27:41 < drzacek> what if I want to run 80mhz chip to run at 100mhz?
2022-01-15T22:27:49 -!- Mangy_Dog [~Mange@user/mangy-dog/x-7397214] has quit [Ping timeout: 256 seconds]
2022-01-15T22:27:50 < zyp> sure, go ahead
2022-01-15T22:27:51 <@karlp> you're just inviting higher errors and reboots
2022-01-15T22:27:56 <@karlp> it's a fools game.
2022-01-15T22:28:04 <@karlp> especially across temp ranges.
2022-01-15T22:28:04 < drzacek> well
2022-01-15T22:28:05 < zyp> or a smaller usable temperature area
2022-01-15T22:28:17 -!- Mangy_Dog [~Mange@user/mangy-dog/x-7397214] has joined ##stm32
2022-01-15T22:28:24 < drzacek> it's for fun
2022-01-15T22:28:33 < zyp> the specs says the chip will work at speed A from temp B to temp C
2022-01-15T22:29:16 < drzacek> surely there are some tolerances
2022-01-15T22:29:22 < zyp> yeah
2022-01-15T22:29:30 < zyp> but now it's up to you to find them
2022-01-15T22:29:38 <@karlp> and it will vary from part to part, so good luck
2022-01-15T22:29:40 < zyp> and process variation is a thing
2022-01-15T22:29:48 <@karlp> it's pointless game with no winner
2022-01-15T22:30:15 < zyp> I mean, for fun there's no harm
2022-01-15T22:30:49 < zyp> but no way I'd ship a product with the cpu overclocked unless I had a really good reason, justifying all the testing required
2022-01-15T22:30:56 < zyp> and I can't imagine what that reason would be :)
2022-01-15T22:31:15 < drzacek> just to check if I got it right-ish
2022-01-15T22:31:55 < drzacek> zyp, I'm making a dev board for myself, as a learning project for all kinds of stuff. product for customers is different kind of shoes, also wouldn't risk it there
2022-01-15T22:31:58 < drzacek> https://lcsc.com/product-detail/Crystals_ECEC-ZheJiang-E-ast-Crystal-Elec-C08000J060_C259040.html
2022-01-15T22:32:05 < drzacek> it says Cl = 20pF
2022-01-15T22:32:21 < zyp> then go for 36pF or so
2022-01-15T22:32:22 < drzacek> so *2 = 40pF, - some, 32pF?
2022-01-15T22:32:25 < drzacek> EACH?
2022-01-15T22:32:28 < zyp> yes
2022-01-15T22:32:31 < drzacek> ok
2022-01-15T22:33:08 < drzacek> I saw in the ANxxx guide version with resistors on the OSC IN/OUT pins. what are those for?
2022-01-15T22:33:20 < zyp> also, fuck that package
2022-01-15T22:33:48 <@karlp> fuck hc49 burn in hell
2022-01-15T22:33:55 <@karlp> that's expensive too
2022-01-15T22:34:29 <@karlp> we may not have summarized it fully, but, 3225 is "currentyly" cheapest, iirc, and in that case, 16 and 25 are cheaper than 8 and 12
2022-01-15T22:35:34 <@karlp> fucking china actually still has super cheap hc49smd wank shit
2022-01-15T22:35:52 <@karlp> https://lcsc.com/product-detail/Crystals_Yangxing-Tech-X322516MOB4SI_C12668.html is a better choice 
2022-01-15T22:35:58 < drzacek> oh?
2022-01-15T22:36:02 <@karlp> sane modern package, cheaper...
2022-01-15T22:36:14 < drzacek> but it has 4 pins
2022-01-15T22:36:16 <@karlp> instead of being the same size as your MCU
2022-01-15T22:36:22 <@karlp> that's ok,2 of them are ground.
2022-01-15T22:37:26 < zyp> even 3225 crystals are annoyingly large when you're trying to fit it and a bunch of caps close to the chip while also bringing out a bunch of signals from neighboring pins
2022-01-15T22:37:50 <@karlp> yeah, I think I tried looking for cheapest in 16 and 25 recently, and it was starting to move to the next size down as being cheaper.
2022-01-15T22:37:55 < drzacek> is the 3225 some common smd footprint?
2022-01-15T22:37:59 <@karlp> on mouser/digikey at leas,t
2022-01-15T22:38:04 < zyp> yes
2022-01-15T22:38:08 <@karlp> yeah, 3225 is a super common crystal footprint
2022-01-15T22:38:09 < drzacek> aka kicad might have it already?
2022-01-15T22:38:12 <@karlp> it does
2022-01-15T22:38:13 < zyp> 3225 means 3.2x2.5mm
2022-01-15T22:38:20 < drzacek> converting from lcsc to kicad is painful
2022-01-15T22:39:39 < fenugrec> Xogium, metallic tape is very special purpose... I doubt you accidentally have some without knowing. And you can definitely feel the difference between metal foil and plastic tape
2022-01-15T22:40:02 < drzacek> how bout zip ties?
2022-01-15T22:40:26 <@karlp> drzacek: what do you mean "converting" ?
2022-01-15T22:41:25 < drzacek> karlp, if lcsc has a part I want, but it doesn't exist on snapeda, mouser or already in kicad, means I have no footprint/symbol
2022-01-15T22:41:46 <@karlp> well, that's just electronics in general,
2022-01-15T22:41:51 <@karlp> same applies to digikey/mouser
2022-01-15T22:42:01 <@karlp> same applies to altium/eagle blah as well
2022-01-15T22:42:11 -!- PureSine [~PureSine@user/PureSine] has quit [Quit: Leaving]
2022-01-15T22:42:18 < drzacek> so I open the easyeda thingy from lcsc, export it, use the other website that converts easyeda boards projects to kicad projects, open in kicad, edit the footprint in foorprint editor, change designator, save as new part, create symbol from scratch
2022-01-15T22:42:34 < drzacek> mouser has this automatic thingy, libraryloader or something
2022-01-15T22:42:44 <@karlp> that sounds way worse than just making symbols yourself
2022-01-15T22:42:47 < drzacek> I just download it to the right dir and gets imported automatically
2022-01-15T22:42:59 < drzacek> I am doing symbols myself. just the footprints
2022-01-15T22:43:06 < zyp> sounds like a hassle
2022-01-15T22:43:09 < drzacek> IT IS
2022-01-15T22:43:25 < zyp> just learn how to do it properly yourself?
2022-01-15T22:43:39 <@karlp> hrm, digikey still has 3225 cheaper than 2016 at least, for 25Mhz
2022-01-15T22:43:52 < drzacek> would love a plugin for kicad, where I just browse lcsc stock and just add stuff to project, symbol into schematic, footprint already assigned, and added to BOM
2022-01-15T22:44:05 < drzacek> zyp, footprint from scratch? nah
2022-01-15T22:44:10 <@karlp> the symbols from some of those auto services are fucking trash anyway
2022-01-15T22:44:15 < drzacek> luckily I only had to do it for few parts
2022-01-15T22:44:18 < zyp> idk about kicad, but altium has an IPC footprint generator making that part quick as fuck
2022-01-15T22:44:30 <@karlp> kicad does too
2022-01-15T22:44:45 <@karlp> symbols probably take more work most of the time as you need to think about it.
2022-01-15T22:44:45 < drzacek> I'm just starting with it, it's my 3rd project
2022-01-15T22:44:56 < drzacek> before I only used mouser parts, now going the cheap way
2022-01-15T22:44:59 < zyp> so unless you've got some super weird/asymmetric part, making a footprint takes like half a minute
2022-01-15T22:45:15 < drzacek> tbh that converting thing is not as long
2022-01-15T22:45:30 < drzacek> few clicks is all it takes.
2022-01-15T22:45:38 < drzacek> but still, it would be nice to have it directly in kicad
2022-01-15T22:45:59 < drzacek> plugins for all major sellers, mouser, digikey, rs-online, lcsc
2022-01-15T22:46:07 < zyp> symbols I generally _prefer_ to make myself
2022-01-15T22:46:25 < zyp> because lots of people are shit at it
2022-01-15T22:46:30 < drzacek> symbols is something else. all what matters is correct pin number. 
2022-01-15T22:46:37 < drzacek> but footprints need to have correct dimensions
2022-01-15T22:46:46 < zyp> exactly
2022-01-15T22:47:00 < zyp> how can you trust some random shit from the web to have correct dimensions?
2022-01-15T22:47:21 < drzacek> I'm downloading it from the source?
2022-01-15T22:47:24 < fenugrec> some autogen are absolute trash (Im̀ thinking of "samacsys" or wherever the hell that came from). Worst symbols ever
2022-01-15T22:47:28 < zyp> what source?
2022-01-15T22:47:30 < drzacek> it's not autogen
2022-01-15T22:47:31 < drzacek> lcsc
2022-01-15T22:47:42 < zyp> lcsc is not a source it's a distributor
2022-01-15T22:47:46 < drzacek> at least that's what I assumed it happens
2022-01-15T22:48:05 < drzacek> so is mouser, and mouser also provides symbols/footprints/3d models
2022-01-15T22:48:12 < zyp> yeah?
2022-01-15T22:49:42 < zyp> the only thing I grab online are 3d models, because that's just visual aid, it doesn't fuck up my design if they are not accurate
2022-01-15T22:51:01 < drzacek> I'll keep in mind
2022-01-15T22:51:03 < drzacek> anyways
2022-01-15T22:51:17 < drzacek> thanks for help, it was bothering me for some time

2022-01-16T01:25:18 < kakium69> Steffanx: manslaughter by diabetus
2022-01-16T01:26:00 < kakium69> you should send rich rebuilds some waffles
2022-01-16T01:26:11 < zyp> BrainDamage, that's the same ones I have
2022-01-16T01:26:27 < zyp> well, only three of those, and more of the round ones without pressure
2022-01-16T01:26:40 < kakium69> they eat stroopwaffles like in every second episode
2022-01-16T01:26:50 < Steffanx> BrainDamage: Hmm me too, but your resolution seems much higher 
2022-01-16T01:27:01 < Steffanx> Only 1hpa here
2022-01-16T01:31:15 < BrainDamage> Steffanx: you can set the resolution of the reporting, your coordinator probably set something low to save on battery

2022-01-16T02:17:39 < ventYl_> kakium69: I am digging some info and it seems that fiat/chrysler is trying to make their diagnostics interfaces safe from circa model year 2017
2022-01-16T02:18:00 < kakium69> safe?
2022-01-16T02:18:08 < kakium69> from what?
2022-01-16T02:18:09 < ventYl_> zyp: what was that page, which contains some DIDs for EVs to read state of charge 'n' stuff?
2022-01-16T02:18:25 < ventYl_> kakium69: from sending bullshit over diagnostic port
2022-01-16T02:23:02 < zyp> ventYl_, this? https://github.com/JejuSoul/OBD-PIDs-for-HKMC-EVs
2022-01-16T02:23:44 < ventYl_> zyp: thx
2022-01-16T02:24:21 < ventYl_> eh, my target victim is not on the list
2022-01-16T02:24:30 < zyp> which?
2022-01-16T02:24:38 < ventYl_> old fiat 500e
2022-01-16T02:24:43 < zyp> ah
2022-01-16T02:24:56 < zyp> that's a leaf drivetrain, isn't it?
2022-01-16T02:24:57 < ventYl_> but based on the evidence on the internets, it looks like it is using UDS
2022-01-16T02:25:28 < ventYl_> dunno, I know it was used in chevy bolt, or adapted from it
2022-01-16T02:28:44 < zyp> hmm, I'm either mixing it up with another car or just plain misinformed
2022-01-16T02:29:18 < ventYl_> yet after studying some details, it is not as appealing to me as it was
2022-01-16T02:30:08 < ventYl_> plus side is that it's battery has thermal management, which is kinda cool for 10 years old EV model
2022-01-16T02:30:42 < zyp> I believe I drove it at a car show some years ago, and I remember the dealer talking about it being based on a leaf powertrain
2022-01-16T02:30:49 < zyp> but he might have been full of shit
2022-01-16T02:30:58 < zyp> or it might be some other car I'm mixing it up with
2022-01-16T02:31:07 < ventYl_> it was apparently never officially sold outside of california and oregon
2022-01-16T02:31:15 < ventYl_> or, at least until like 2019
2022-01-16T02:31:25 < zyp> yeah, pretty sure they were grey imports
2022-01-16T02:31:48 < ventYl_> that drivetrain is designed by bosch, dunno who designed leaf
2022-01-16T02:32:10 < ventYl_> it is apparently quite similar to what bmw i3 has
2022-01-16T02:33:21 < zyp> hmm
2022-01-16T02:33:52 < zyp> there's a bit over 2300 of them in norway, but the statistics doesn't distinguish between new and old
2022-01-16T02:34:07 < ventYl_> new is MY2020+
2022-01-16T02:34:07 < zyp> apparently three out of four are grey imports
2022-01-16T02:34:30 < zyp> yeah, but the stats I'm looking at doesn't have that
2022-01-16T02:35:01 < ventYl_> they only contain make/model and amount of registered cars?
2022-01-16T02:35:14 < zyp> https://elbilstatistikk.no/
2022-01-16T02:39:32 < ventYl_> oh, I assume that those grey imported are the old models
2022-01-16T02:40:03 < ventYl_> which is kinda suprising given the fact, that in cold climate, range of fiat 500e drops some 43%
2022-01-16T02:41:04 < ventYl_> iirc, if you grey-import car into norway, you have to pay some horrible tax, does it apply to EVs too?
2022-01-16T02:42:56 < zyp> no, the reason EVs are so popular here is because they are exempt from both VAT and the registration tax
2022-01-16T02:43:05 < zyp> *first time registration tax
2022-01-16T02:44:16 < ventYl_> still makes little sense to use fiat in norway
2022-01-16T02:44:19 < zyp> they apply equally to buying a car from a dealer or importing yourself, it's just that when you buy a car from a dealer it's already baked into the purchase price
2022-01-16T02:44:20 < ventYl_> the old one
2022-01-16T02:45:22 < zyp> yeah, I figure they were primarily purchased by people looking at the old leafs but wanting something smaller
2022-01-16T02:45:39 < zyp> since the performance numbers look similar
2022-01-16T02:45:50 < ventYl_> that's true, leaf has similar battery
2022-01-16T02:45:56 < ventYl_> a tad bit bigger
2022-01-16T02:46:34 < zyp> still way better than wife's old car :p
2022-01-16T02:46:48 < ventYl_> what's that?
2022-01-16T02:47:06 < zyp> she had an peugeot ion, which is a rebranded mitsubishi i-miev
2022-01-16T02:47:20 < zyp> from 2012
2022-01-16T02:47:21 < ventYl_> apparently still better than renault zoe
2022-01-16T02:47:39 < ventYl_> which seems to score an achievement of being less reliable than most unreliable ICE cars
2022-01-16T02:47:39 < zyp> no?
2022-01-16T02:47:50 < zyp> hmm, idk
2022-01-16T02:48:06 < zyp> I haven't heard much about zoe having poor reliability here
2022-01-16T02:49:09 < zyp> mostly the issue with zoe in norway is that they refuse to charge when N and PE is not at the same potential, which it isn't for most of our electricity grid
2022-01-16T02:49:18 < zyp> so they need to fuck around with isolating transformers
2022-01-16T02:50:11 < zyp> and the early generations also doesn't do DC fast charging, just 22kW or 43kW AC
2022-01-16T02:50:24 < zyp> and there's almost no AC outlets over 22kW anywhere
2022-01-16T02:50:26 < ventYl_> yeah, same for 500e
2022-01-16T02:51:09 < ventYl_> yet, charger is on-board, but outside of batpack, so you can essentially hack DC charging into 500e
2022-01-16T02:53:42 < zyp> the ion had pretty poor range and even DC charging was slow as fuck
2022-01-16T02:54:15 < zyp> but then again it worked well for trips around town, picking up and dropping off the kid at kindergarden and such
2022-01-16T02:58:23 < ventYl_> yeah, that would exactly the use case for me
2022-01-16T02:58:43 < ventYl_> even worn out 500e battery would probably have sufficient range for like 95% of my trips

2022-01-16T03:22:32 < BrainDamage> oh and let's not forget dnscrypt and dnscurve ..
2022-01-16T03:24:39 < kakium69> what could cause those to fail?
2022-01-16T03:24:46 < kakium69> do those require ip6v?
2022-01-16T03:24:51 < BrainDamage> no
2022-01-16T03:25:03 < BrainDamage> but several run on port 443
2022-01-16T03:25:15 < BrainDamage> which is nominally for tls/https
2022-01-16T03:26:09 < BrainDamage> if the firewall is extremely anal, it might block if the source is not on port 443, or if the traffic doesn't look like tls/https, which is the case for dnscrypt, that being said, I don't know which one apple uses
2022-01-16T03:27:01 < BrainDamage> and this is for encryption, there's a separate standard for signatures called dnssec, which often caching resolvers strip ...
2022-01-16T03:27:09 < BrainDamage> in short, it's a clusterfuck
2022-01-16T03:27:26 < kakium69> hmm

2022-01-16T12:24:36 < BrainDamage> jadew: tea has pretty much trace nutrients and the only stuff that's active is caffeine, theanine, oxalates and polyphenols
2022-01-16T12:24:54 < BrainDamage> oxalates would give you kidney stones if you drink liters of tea per day
2022-01-16T12:25:34 < BrainDamage> polyphenols might help a bit against aging, but the quality of research is super low
2022-01-16T12:25:39 < PaulFertser> And probably even if you do not. My grandfather and father both had them despite not being big fans of tea.
2022-01-16T12:28:26 < PaulFertser> Hm, probably they had gallstones in fact, as my father doesn't suffer from the stones after having gallbladder removed.
2022-01-16T12:28:48 < BrainDamage> also, got a 2nd set of peaks, not sure if it's the wave from the other side of the world or a reflection, negative would suggest a reflection, but there's no polarity inversion

2022-01-16T12:30:16 < BrainDamage> the oxalates in tea aren't in a bioavailable form, so he would've drank only half of the poison
2022-01-16T12:30:37 < BrainDamage> there must've been something else in his diet to combine and make it bioavailable

2022-01-16T20:20:00 < Laurenceb> does hwclock -r on Lunix just read the RTC ?
2022-01-16T20:20:09 < Laurenceb> there isnt any weird processing inbetween?
2022-01-16T20:23:01 < BrainDamage> no, just syscalls to get it
2022-01-16T20:23:50 < BrainDamage> you can read /dev/rtc0 too if you want to NIH it
2022-01-16T20:29:40 < Laurenceb> ok
2022-01-16T20:29:55 < Laurenceb> hmm wtf, looks like Lunix is correcting RTC every 9.7 minutes

2022-01-16T20:34:55 < Laurenceb> ok wtf
2022-01-16T20:37:11 < PaulFertser> Laurenceb: Linux writes to hw rtc every 11 minutes if NTP is in sync. That's there for many many years.
2022-01-16T20:38:13 < Laurenceb> yeah
2022-01-16T20:38:40 < Laurenceb> that code looks like it sets RTC to subsecond accuracy, and my RTC is <10ms off atm
2022-01-16T20:39:01 < Laurenceb> yet I dont see corrections every 11min
2022-01-16T20:39:11 < Laurenceb> no way my RTC is that good surely

2022-01-16T22:34:46 < PaulFertser> Laurenceb: it was 11 minutes or 11 + 1 minute when it was an unlucky moment to update.
2022-01-16T22:34:57 < PaulFertser> But probably different now.
2022-01-16T22:35:21 < PaulFertser> Laurenceb: why do you care much?
2022-01-16T22:35:58 < Laurenceb> PaulFertser: I;m just trying to understand whats going on
2022-01-16T22:37:50 < PaulFertser> Laurenceb: why do you care about RTC time? It's only essential first minute after reboot.
2022-01-16T22:38:02 < PaulFertser> Then you get NTP sync and voila
2022-01-16T22:38:17 < Laurenceb> yeah I need it for precision telemetry at all times
2022-01-16T22:38:25 < Laurenceb>  <100ms error
2022-01-16T22:39:46 < PaulFertser> Laurenceb: do you mean you want to do precision telemetry before a GNU/Linux system fully booted and running?
2022-01-16T22:40:17 < Laurenceb> no
2022-01-16T22:40:34 < Laurenceb> sometimes the network isnt available for a while after boot
2022-01-16T22:40:40 < PaulFertser> Laurenceb: so, how is RTC getting involved ever?
2022-01-16T22:41:00 < PaulFertser> Laurenceb: and you count on RTC quartz without having it temperature-controlled?
2022-01-16T22:41:01 < Laurenceb> between boot time and the network being available I need to know the exact time
2022-01-16T22:41:13 < Laurenceb> yeah its good enough to last for an hour or so
2022-01-16T22:41:17 < Laurenceb> thats all I need
2022-01-16T22:41:58 < PaulFertser> Laurenceb: so is it not enough for you that it's getting synced to correct time every 11 minutes?
2022-01-16T22:42:36 < Laurenceb> thats ok, but I just need to check everything is working correctly and that the RTC drift is acceptably low

2022-01-16T22:47:24 < PaulFertser> Laurenceb: you can't check the drift while you're constantly updating it with NTP, so you should stop NTP and see I guess.

2022-01-16T22:51:20 < PaulFertser> catphish: (vw dieselgate) no, the problem was that it was pumping enough "adblue" (urea) when it knew it was being tested for emissions but not when it was on the road. So it was just to avoid having diesel drivers buy and fill adblue between service intervals apparently. Even though it's sold everywhere for lorries.
2022-01-16T22:53:07 < catphish> PaulFertser: really that simple? :|

2022-01-16T22:58:13 < englishman> the urea froze, cracking the plastic bottle it is kept in, and the shit is replaced as a unit with the heater and pump
2022-01-16T22:58:40 < mawk> put some tape on the bottle

2022-01-16T23:13:20 < Xogium> well… that was my last day living on my own today. Tomorrow I get to meet my caregiver
2022-01-16T23:14:06 < Xogium> just as well, I guess. Honestly, it's getting all to hell. I'm losing my balance a lot of the time, and my ears are so messed up I accidentally run into walls and doors
2022-01-16T23:14:38 < mawk> that's sad to hear Xogium 
2022-01-16T23:14:41 < mawk> is it a man or a woman
2022-01-16T23:14:47 < mawk> do you have a dog?
2022-01-16T23:15:17 < Xogium> will be a woman
2022-01-16T23:15:28 < Xogium> no dog :) just my old trusty white cane
2022-01-16T23:16:01 < Xogium> like… I guess it will vary, maybe tomorrow will be a better day, but it's unpredictable
2022-01-16T23:16:34 < Steffann> Is it hard to get a dog in la france?
2022-01-16T23:16:52 < Xogium> I don't know
2022-01-16T23:17:25 < Steffann> How does such caregiver work? Someone paid by the government to live in your house?
2022-01-16T23:17:34 < Xogium> but you can't get a guide dog unless you're beyond very good with a cane and can orient yourself
2022-01-16T23:17:42 < Xogium> that's something I always had trouble with
2022-01-16T23:18:40 < Xogium> not sure if it's the government behind it… But they get to live with people that can't live on their own anymore for whatever reason
2022-01-16T23:19:19 < Steffann> so a beneficial for both i assume?
2022-01-16T23:19:29 < Xogium> I mean, it would be good if I had someone in my life too, that would work also, but since I don't
2022-01-16T23:19:38 < Xogium> yeah, probably 
2022-01-16T23:20:11 < Xogium> good thing this place has 2 rooms, can turn the other one into a bedroom
2022-01-16T23:20:50 < Xogium> god this is horrible
2022-01-16T23:21:08 < Xogium> you know how people that drank too much walk ? Like they stumble around
2022-01-16T23:21:16 < Xogium> that's what I've been doing all day
2022-01-16T23:22:43 < Xogium> no real vertigo today… Just not able to walk straight and I have a nasty bump on the head thanks to the door reminding me it was there

2022-01-16T23:31:35 < Xogium> I'm sorry for my weird mood… I think I should just try and get some sleep
2022-01-16T23:31:39 < PaulFertser> Xogium: my friend developed some very serious vertigo so that he had to be treated in hospital for more than a week iirc, something like inner ear inflammation. But then it was cured.
2022-01-16T23:32:47 < Xogium> PaulFertser: yeah, they did a lot of checks for that, and honestly everything appears fine. It's just my ears being too full of liquid

2022-01-16T23:34:41 < Laurenceb> nope no luck

2022-01-17T00:24:08 < steve__> I'm checking a serial port for incoming data by using a polling loop that does select and then read(1) byte at a time.  Sometimes the read blocks, even tho select says there's something to read.  Changing to a nonblocking read resolved the symptom but it is strange that read blocked after select.  Internet says this is possible, but for 1 byte from a serial port?  Has anyone seen this?

2022-01-17T11:59:09 < PaulFertser> karlp: oh, fail how? Got some pics?
2022-01-17T11:59:23 <@karlp> dimensions aren't good enough,
2022-01-17T11:59:42 <@karlp> the dude who delivered said, "make sure to measure it, it might need to be re-calibrated"
2022-01-17T11:59:55 <@karlp> and I can't work with that, that's why we tried to outsource
2022-01-17T11:59:58 < PaulFertser> Yes, but how bad is not good enough?
2022-01-17T12:00:07 <@karlp> well, the pcb doesn't fit in the 3d printed case 
2022-01-17T12:00:46 <@karlp> the cutouts are also super crap edges, compared to the injection moulded+milled original we have.
2022-01-17T12:00:50 < PaulFertser> What plastic? Are the walls too thick or just the whole part is shrunk?
2022-01-17T12:01:00 <@karlp> they gave us one in petg and one in pla.
2022-01-17T12:01:37 <@karlp> and honestly, the goal with trying a local place was to see if we could have a useful enough conversation with them about it, but it's just kinda meh.  we'll see how the internet print shows up, whether it's a bigger problem or not.
2022-01-17T12:02:24 < PaulFertser> I wonder if you're talking about 1 mm error on 100 mm part or something like that.
2022-01-17T12:03:33 <@karlp> I likely am, but that' still "can I use 3d printing for this need? yes/no" which was the question i needed answering..
2022-01-17T12:04:22 < PaulFertser> Why is scaling it to 101 % uniformly is not an option?

2022-01-17T12:11:26 <@karlp> aintnobodygottimeforthat.gif
2022-01-17T12:11:45 <@karlp> can you imagine getting a pcb back and it was uniformly 2% too big or small?
2022-01-17T12:11:51 <@karlp> "oh, just scale it by x% and re-order"
2022-01-17T12:11:53 <@karlp> gtfo
2022-01-17T12:13:04 <@karlp> the goal in this specific case was to get a 3d print of the casing with some alternative cutouts, to check for fit, rather than paying the manufacturer for another round of custom milling.
2022-01-17T12:18:44 < BrainDamage> I assume telling them that they need to calibrate their shit didn't go well?
2022-01-17T12:19:12 < BrainDamage> i mean, it's not like they need external input to print standard shapes
2022-01-17T12:22:24 < mawk> they don't have calipers maybe
2022-01-17T12:22:43 < mawk> so they asked karlp to kindly measure himself
2022-01-17T12:25:46 <@karlp> BrainDamage: if they're prepared to print and hand off stuff and say, "hey, you should maybe measure it maybe" I'm not really excited about even trying to work with them further.

2022-01-17T13:10:35 < BrainDamage> yeah, that's a red flag
2022-01-17T13:11:09 < PaulFertser> So pro
2022-01-17T13:11:42 < PaulFertser> Didn't they agree to reprint it if dimensions were wrong?
2022-01-17T13:12:27 <@karlp> probably, but the print quality was kinda meh, and if that's going to be the process, how can I even trust what's the problem? my design or their realization?
2022-01-17T13:14:27 < PaulFertser> Them being local probably means they can be more cooperative and open about it. FDM is quite a quirky technology but working together with an experienced person might give nice results for reasonably cheap eventually.
2022-01-17T13:15:04 <@karlp> so, I've not complained to them or anything yet, I'm going to see what the interent of 3d printing service people can provide.
2022-01-17T13:15:30 < PaulFertser> I hope you can show the photos later so that print quality can be judged.
2022-01-17T13:15:39 <@karlp> and then make a final decision, but I'm not really excited about having to work with them on getting it right.  having a local company was attracative if they could _improve_ things
2022-01-17T13:16:02 < PaulFertser> You know how sometimes the optimal way seems to be too hard at first.
2022-01-17T13:16:57 <@karlp> we shall see :)
2022-01-17T13:17:35 <@karlp> I mena, I could have just given the files back to the case maker and said, "mill this insted" but it is more expensive for iterating, 
2022-01-17T13:17:48 <@karlp> not any slower though, the case company can do custom milling turnarounds really quickly
2022-01-17T13:18:00 < PaulFertser> Milling alu?
2022-01-17T13:19:44 < PaulFertser> Sometimes small tweaks to the model can compensate for the shortcomings of FDM.
2022-01-17T13:24:45 <@karlp> yes, but that's only interesting if the goal is FDM
2022-01-17T13:24:58 <@karlp> no, milled abs+"stuff"
2022-01-17T13:25:27 <@karlp> you're remarkably motivated in me doing more with some local duders :)
2022-01-17T13:27:53 < PaulFertser> I like the idea of working together with local nerds, yes.
2022-01-17T13:31:40 < srk> you can easily print things to spec - measure the result, compare to expected value, adjust scale in slicer and print again

2022-01-17T15:38:39 < fenugrec> I'm still shocked that karl's locals charged money for 3dprint but didn't ask basic questions like "which are the critical dimensions", and validated + iterated behind the scenes to hand a compliant print... tolerances are essentially their contract; any machine shop that got drawings for something they can't produce would refuse the work / work with the customer to adjust design, not just "this is
2022-01-17T15:38:41 < fenugrec> a best effort, hope it works lol"
2022-01-17T15:39:09 < englishman> a machine shop has a barrier to entry higher than 3 digits
2022-01-17T15:39:39 < fenugrec> yes, because machine tools are (still) mostly orders of magnitude more expensive to buy and operate
2022-01-17T15:40:04 < fenugrec> although top end 3dprint probably turn the tables
2022-01-17T15:40:15 <@karlp> fenugrec: sending the same file as the locals attempted printing to a cloud service it was rejected as "we can't make that" and when I asked for follow up they said, "we won't be able to make the surfaces look nice, and we are unlikely to be able to get you the tolerance you need with FDM, perhaps try a resin print"
2022-01-17T15:40:59 <@karlp> the local guys seem to be mostly a reseller of hobby 3d printer parts and materials, who are trying to get printing going on the side.
2022-01-17T15:43:51 < fenugrec> a buddy had some metal 3dprints  made for a proto, it's impressive. And not super expensive considering the alternative of 4/5-axis milling

2022-01-17T16:42:48 < Xogium> well… that's the thing. None of that appears to be going on
2022-01-17T16:43:03 < Xogium> just… my ears are getting too full of liquid no matter that they drain some away
2022-01-17T16:49:53 < Xogium> varies wildly with each day, sometimes no vertigo, sometimes nothing at all, sometimes like today it feels like my ears are too full
2022-01-17T16:50:41 < Xogium> but god the vertigo is the worse thing. It's too intence to even stand up when it hit, pushes me down and I can't do a thing till it goes away
2022-01-17T16:52:24 < mawk> vertigo is awful
2022-01-17T16:53:02 < Xogium> sometimes I wonder if I'm the one spinning round and round or if the room is, or both
2022-01-17T16:54:14 < Xogium> or maybe nothing spins and it's all in my brain
2022-01-17T17:03:38 < Xogium> mawk: honestly part of me just want to die

2022-01-17T17:48:33 < mawk> that feeling is temporary Xogium 
2022-01-17T17:48:37 < mawk> it will become easier
2022-01-17T17:50:19 < Xogium> yeah… I hope it is
2022-01-17T17:51:52 < fenugrec> I wonder what EU consultant rates are like... at least 100E/h I would imagine
2022-01-17T17:52:36 < mawk> it's not comparable at all to your situation Xogium but when I lost my right arm to paralysis I was at peace with it very quickly
2022-01-17T17:52:38 < mawk> but maybe I'm insane
2022-01-17T17:53:56 < mawk> how much older than you is the caregiver Xogium 
2022-01-17T17:54:16 < Xogium> she's about 6 years older
2022-01-17T17:54:36 < mawk> she will be here fulltime?
2022-01-17T17:54:49 < Xogium> yeah, most probably
2022-01-17T17:55:10 < Xogium> we don't want me hitting my head on the shower tiles
2022-01-17T17:55:17 < mawk> yeah
2022-01-17T17:55:20 < Xogium> or falling down the stairs
2022-01-17T17:55:32 < mawk> my grandpa was forced to stay in a wheelchair all the time because of vertigo, but apart from that he could've walked normally
2022-01-17T17:55:43 < mawk> but he has fucked up kidneys so we couldn't medicate him, you're not in that case
2022-01-17T17:55:54 < mawk> the magic pillz will be found and your vertigo will go away
2022-01-17T17:56:36 < Xogium> yeah, that alone would feel good
2022-01-17T17:57:15 < Xogium> honestly when it's at its worse, I can't even swallow meds to counter the nausea, I throw them back up
2022-01-17T17:58:00 < mawk> that's why my nausea meds are sublingual
2022-01-17T17:58:03 < mawk> don't have to swallow them
2022-01-17T17:58:10 < mawk> you can ask for vogalib in pharmacy
2022-01-17T17:58:12 < mawk> it's OTC
2022-01-17T17:58:21 < mawk> ask for the orodispersable version
2022-01-17T18:01:53 < mawk> how does your TTS thing work when I mix french and english Xogium 
2022-01-17T18:01:56 < mawk> not very good I suppose
2022-01-17T18:02:39 < Xogium> mawk: actually not that bad my tts voice is french, but it has some rules for pronouncing english mostly correctly
2022-01-17T18:02:46 < mawk> ah nice
2022-01-17T18:02:51 < mawk> is it french quebec accent?

2022-01-17T18:04:42 < fenugrec> ventYl_, even if billing as e.g. a self-employed contractor vs employee ?
2022-01-17T18:05:45 < ventYl_> fenugrec: local employmee rates are around 25E/h brutto
2022-01-17T18:06:04 < fenugrec> hm. lower than I imagined
2022-01-17T18:06:16 < ventYl_> well, it still translates to shitload of money where I live
2022-01-17T18:06:37 < fenugrec> yea, cost of living is not exactly uniform accross eu
2022-01-17T18:07:10 < ventYl_> I've heard that automotive consultant rates paid between companies are like 82 E / h
2022-01-17T18:07:21 < ventYl_> so I set myself somewhere in between at 60
2022-01-17T18:08:30 < fenugrec> aroudn here there's no shortage of work, you can get probably 15-20C$ , ~ 10E for untrained menial work
2022-01-17T18:09:13 < fenugrec> consulting probably >5x that but I have no solid info
2022-01-17T18:09:47 < ventYl_> well, if you are on-site, then in Berlin you can ask 100 and you will get it
2022-01-17T18:09:53 < fenugrec> ach
2022-01-17T18:10:29 < ventYl_> you'll be listening that you are friggin expensive, but you'll get it

2022-01-17T18:49:15 < BrainDamage> normally transporting energy costs energy
2022-01-17T18:49:30 < BrainDamage> so unless energy is really cheap it's better to make electricity close to you
2022-01-17T18:52:37 <@karlp> yes, there are talks on and off about a sea cable
2022-01-17T18:52:48 <@karlp> it would be the longest ever aiui, so it's not "tomorrow"
2022-01-17T18:53:00 <@karlp> but I fully expect it to happen sooner or later.
2022-01-17T18:53:50 <@karlp> both to deliver surplus here to (particularly) .uk spot markets, and also to pull in when spot prices are low and use it for pumping.
2022-01-17T18:54:22 <@karlp> aa certain group of people claim that because that type of cable is "expensive" we "must" dam more to have "enough" surplus to make it profitable on their own ROI guidelines.
2022-01-17T18:54:25 <@karlp> I hate those cunts.
2022-01-17T18:54:45 <@karlp> I see it as jsut energy security having some interconnects.
2022-01-17T18:54:59 <@karlp> in the short term, I'd like to actually have a proper transport ring domestically....
2022-01-17T18:55:21 <@karlp> we have local farmers complaining abotu shitty power, but they won't allow new power lines,
2022-01-17T18:55:44 <@karlp> and the national grid people claim to not have a mandate to do buried cables, they "must" choose overhead lines that no-one wants.
2022-01-17T18:56:32 <@karlp> so we have "entrepreneurs" planning on shitty little private 4MW hydro plants where they can avoid some environmental oversight, and claim it's for "energy security" for the local area, and get the local community all split on it.
2022-01-17T18:56:36 <@karlp> "muh jerbs"
2022-01-17T18:56:50 <@karlp> fucking classic short sighted money talks crap
2022-01-17T18:57:09 <@karlp> I don't imagine any of that is really all taht different to anywhere else.
2022-01-17T18:57:43 <@karlp> and in the meantime, we ahve big chunks of supply in both ends of the coutnry and zero way of getting it usefully to the other side right now.
2022-01-17T18:57:59 <@karlp> oh, and we're doing a shit ton of "green" bitcoin mining, because "surplus" power joy
2022-01-17T18:58:23 < kakium69> karlp: it's what I figured it would be in megaproject category to transport electricity from .is
2022-01-17T18:59:08 < kakium69> has anyone thrown any ballpark figures of the budget?
2022-01-17T18:59:48 <@karlp> I'm sure they have, but they're all handwaving and made up at this point, 
2022-01-17T19:00:04 <@karlp> and that sort of project would all be funded with opaque subsidies anyway
2022-01-17T19:01:39 < mawk> BrainDamage: transporting fuel is free
2022-01-17T19:01:44 < mawk> just burn it in the boat that transports it
2022-01-17T19:04:08 <@karlp> that's a pretty fucked up understanding of free there mawk
2022-01-17T19:04:35 < mawk> why
2022-01-17T19:04:40 < mawk> the price of fuel already comprises its cost of extraction
2022-01-17T19:04:46 < mawk> it's not something you pay on top of it
2022-01-17T19:04:56 < kakium69> it's not free but rather convinient though
2022-01-17T19:05:07 < mawk> it only works for fuel though
2022-01-17T19:05:09 < mawk> not gas I think
2022-01-17T19:05:14 < mawk> fuel = petroleum
2022-01-17T19:05:21 <@karlp> the price of fuel sitting in a tank in location A is very much not the price of delivering that to location B
2022-01-17T19:05:45 <@karlp> and in the context of iceland, what exactly are you going to be transporting?
2022-01-17T19:05:52 < englishman> i wonder if filling a tanker up with lipos and sending it to the mainland (using bunker fuel of course) will please the nimbys
2022-01-17T19:06:12 <@karlp> englishman: we're still working on cruise ships and bunker fuel.

2022-01-17T19:06:22 <@karlp> norway has done well, .is..... less so.
2022-01-17T19:06:45 < englishman> if .is requires every citizen leaving its borders to bring 10kg of charged lipos with them...
2022-01-17T19:06:49 <@karlp> we've still got them just using bunker fuel _in habour_ even...

2022-01-17T19:07:35 < englishman> .is airlines will have to start using the "fat american" weight & balance schedule
2022-01-17T19:07:58 <@karlp> heh, this product seeeems to have bluetooth _only_ for connecting a printer to it.
2022-01-17T19:08:04 <@karlp> not for using it for API control.
2022-01-17T19:08:10 <@karlp> RS232 port can be for either.

2022-01-17T21:48:07 < Steffann> -using 
2022-01-17T21:49:42 < Laurenceb> for https post
2022-01-17T21:50:20 < Steffann> Why you use libcurl or whatever lib does it all for you?
2022-01-17T21:50:27 < Steffann> Don't you use*
2022-01-17T21:54:11 < Laurenceb> I'm using raw c code
2022-01-17T21:54:14 < Laurenceb> https://beta.openssl.org/docs/manmaster/man3/SSL_CTX_load_verify_locations.html
2022-01-17T21:54:18 < Laurenceb> maybe I need that
2022-01-17T21:58:00 <@karlp> BrainDamage is right, learning how to use antlr was fucking amazing experience.
2022-01-17T21:58:29 <@karlp> and there's cool gui tools to help you test it iteratively.
2022-01-17T21:58:40 <@karlp> might be tedious with binary files though...
2022-01-17T22:00:01 < mawk> your code is a bit ugly Laurenceb 
2022-01-17T22:00:05 < mawk> is that the coding style of your company?
2022-01-17T22:00:16 < mawk> is your space key broken?

2022-01-17T22:00:38 < zyp> mawk, nah, we've been making fun of it since forever
2022-01-17T22:01:10 < mawk> either write size, or abbreviate as sz, siz sounds like a middle-eastern name
2022-01-17T22:01:56 < Laurenceb> lol ok
2022-01-17T22:02:42 < Laurenceb> ok wtf /etc/ssl/certs is huge
2022-01-17T22:02:48 < mawk> yeah it needs all CA of everyone
2022-01-17T22:03:49 < Laurenceb> this is just weird
2022-01-17T22:04:01 < Steffann> Yeah, why waste time writing "raw c code" Laurenceb 
2022-01-17T22:04:11 < Laurenceb> SSL_CTX_load_verify_locations needs a path but also a filename wtf
2022-01-17T22:04:43 < mawk> this is to verify a CA in particular Laurenceb 
2022-01-17T22:04:50 < mawk> why do you think you need that function?
2022-01-17T22:05:19 < Laurenceb> to verify that the server I'm talking to is legit
2022-01-17T22:05:35 < mawk> put NULL as the ca path and filename
2022-01-17T22:05:39 < Laurenceb> currently I get this error when I try X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT
2022-01-17T22:05:42 < Laurenceb> oh ok
2022-01-17T22:06:25 < Steffann> What you used antlr for karlp ?
2022-01-17T22:06:33 < Laurenceb>  SSL_CTX_load_verify_locations(c->sslContext, NULL, NULL);
2022-01-17T22:06:34 < Laurenceb>  long x509_status=SSL_get_verify_result(c->sslHandle);//chain of trust?
2022-01-17T22:06:36 < mawk> why are you not using int SSL_CTX_load_verify_dir
2022-01-17T22:06:36 < Laurenceb> ^like that?
2022-01-17T22:06:42 < mawk> yeah I supose
2022-01-17T22:06:47 < mawk> but check the result of the function no?
2022-01-17T22:06:50 < Laurenceb> I'll try running it
2022-01-17T22:07:10 < mawk> if the cert isn't valid you need to check
2022-01-17T22:07:36 < mawk> like if the path isn't valid etc
2022-01-17T22:09:18 < Laurenceb> nope no change in behaviour with NULL
2022-01-17T22:09:23 <@karlp> Steffann: umm, writing a camel integration to a telnet interface to some iptv equipment :)
2022-01-17T22:09:28 <@karlp> was for $job a while ago
2022-01-17T22:09:47 <@karlp> but it was _super_ reassuring when you just got a parser and could just _know_ that it was ok.
2022-01-17T22:09:56 <@karlp> highly recommend.
2022-01-17T22:10:16 <@karlp> would not really reocmmend bison&/yacc that's like playing in the 80s, but still probably valid I guess.
2022-01-17T22:13:25 < mawk> why are you not using the function I said Laurenceb 
2022-01-17T22:13:28 < mawk> SSL_CTX_load_verify_dir
2022-01-17T22:13:54 < mawk> is the cert you're checking valid anyway?
2022-01-17T22:14:03 < mawk> check it with openssl req instead of your toolz
2022-01-17T22:47:11 < Laurenceb> ok nvm I fixed it
2022-01-17T22:47:28 < Laurenceb> just using NULL,NULL works if called in the correct order, thanks for the help
2022-01-17T22:48:31 < Laurenceb> 0
2022-01-17T22:48:32 < Laurenceb> The operation failed because CAfile and CApath are NULL or the processing at one of the locations specified failed. Check the error stack to find out the reason.
2022-01-17T22:48:34 < Laurenceb> kek wut
2022-01-17T22:48:59 < Laurenceb>  "this error condition fixed it"
2022-01-17T22:49:51 < mawk> lol
2022-01-17T22:49:58 < mawk> yes so why are you not using SSL_CTX_load_verify_dir
2022-01-17T22:53:08 < Laurenceb> https://github.com/openssl/openssl/blob/79b2a2f2eedb9d6b24a3f6748332328cf54568fb/ssl/ssl_lib.c#L4401
2022-01-17T22:53:12 < Laurenceb> wait what the fuuuuu
2022-01-17T22:56:44 < mawk> well yes that call is doing precisely nothing Laurenceb 
2022-01-17T22:56:50 < mawk> so again why are you not trying what I said
2022-01-17T22:56:54 < Laurenceb> hmm maybe some sort of cachey behaviour, I tried it with the correct .pem file and the directory, then with just the directory, then NULL NULL
2022-01-17T22:56:58 < mawk> SSL_CTX_load_verify_dir

2022-01-17T23:22:56 <@karlp> anyone understand what DIVR and DIVC are trying to do in ST code?  these two numbers are _close_ but absolutely not the same thing! https://paste.jvnv.net/view/hqtSJ
2022-01-17T23:23:48 <@karlp> they have DIVF => x/y,  DIVC => (x+y-1)/y and this DIVR => (x+(y/2))/y which I'm not sure I've ever seen before...
2022-01-17T23:24:15 <@karlp> is this trying to get a rounded up or rounded down integer operation or something weird?

2022-01-17T23:26:09 < mawk> divr is doing (x+(y/2))/y which looks definitely like a way to do a ceil
2022-01-17T23:26:18 < mawk> ceil of (x/y)
2022-01-17T23:27:18 <@karlp> looks like it mustbe, because later they try using DIVR and DIVF to work out how "wrong" they were earlier, and to try and correct the total number of ticks. required.
2022-01-17T23:27:50 <@karlp> looks like they're actually keeping that between "sleeps" to make sure that they stay "correct" I think, so that's kinda neat, if a lot more complicated than I expected.

2022-01-17T23:28:40 <@karlp> I guess ceil is just to make sure they sleep for "1" rather than "0" in some cases.
2022-01-17T23:29:21 <@karlp> I think they made this more complicated than it needs ot be, but that wouldn't be a first.
2022-01-17T23:32:13 < mawk> sorry it's not ceil it's round
2022-01-17T23:32:25 < mawk> ceil would be (x + (y-1))/y or something like that
2022-01-17T23:33:05 <@karlp> round... towardswhat? "away from zero" ?
2022-01-17T23:33:17 <@karlp> yeah, divc is defined as x+y-1/y
2022-01-17T23:33:26 <@karlp> and divf is x/y
2022-01-17T23:33:37 <@karlp> so floor, ceiling and "round"
2022-01-17T23:50:32 <@karlp> bleh, doing this "properly" is going to be tedious isn't it.

2022-01-18T00:39:54 < zyp> the flash_init/rcc_init stuff are really old style that just sticks around because they've worked well enough for what I've needed them for to not bother replacing them yet
2022-01-18T00:40:26 < zyp> but they are silly hardcoded shit that doesn't scale beyond the assumptions they were written with :p
2022-01-18T00:42:09 < zyp> I'd like to have a simple but flexible and still sane way of configuring the clock tree, i.e. without doing crazy shit like a full solver implemented with template metaprogramming
2022-01-18T00:42:41 < zyp> but that kinda sounds like a «pick max two out of three» problem, so for now I'm sticking with simple
2022-01-18T00:44:48 < zyp> I think the most reasonable solution to that would be to make something like clock profiles, I guess similar to what libopencm3 does, and provide a few default ones but also give the option to do custom ones
2022-01-18T00:47:05 < bitmask> zyp hows the vulkan going

2022-01-18T00:51:28 <@karlp> needed more const in the right places :)
2022-01-18T00:51:58 <@karlp> probably also needs a way of those being proivded by impls instead of globally, but yeah, that's exactly the sort of code I was looking for thangs :)

2022-01-18T00:53:59 < machinehum> Can you pop a 78 ball ddr3 where you would put a 96 ball?
2022-01-18T00:54:12 < machinehum> It looks like the pins line up pretty well with some redundancy on the 96 ball
2022-01-18T00:54:52 < zyp> probably
2022-01-18T00:55:27 < zyp> I mean, I don't know, but I have the impression modern memories tend to have compatible footprints across package sizes
2022-01-18T00:55:41 < zyp> i.e. only differing in mechanical balls
2022-01-18T00:56:55 < machinehum> https://imgur.com/a/kpc5ksO
2022-01-18T00:56:57 < machinehum> Looks close
2022-01-18T00:57:30 < machinehum> Might ask on #fpga
2022-01-18T00:57:38 < zyp> oh, no
2022-01-18T00:58:17 < zyp> these are different widths, aren't they?
2022-01-18T00:58:24 < zyp> as in bus widths
2022-01-18T00:59:35 < zyp> if it's on a fpga board, you can probably just instance the memory controller with the appropriate width though
2022-01-18T01:01:25 < zyp> the leftmost footprint is 16 bits wide, the other is 4 or 8 bits wide
2022-01-18T01:02:55 < zyp> all the balls on the top three rows are either more power or related to the top 8 bits
2022-01-18T01:03:19 < zyp> so as long as your memory controller has the appropriate width for the actual memory chip fitted, you should be good

2022-01-18T01:21:40 < machinehum> Right of course
2022-01-18T01:22:06 < machinehum> For 16bit wide mcu you need 2x 8bit rams if I remember properly
2022-01-18T01:22:20 < machinehum> Is normally how it gets rigged up
2022-01-18T01:23:31 < machinehum> mawk: https://imgur.com/a/5fM86pp wasn't that bad
2022-01-18T01:24:01 < machinehum> However these are 8bit wide ddr chips, I think I should probably change my design to use 8bit wide
2022-01-18T01:24:12 < machinehum> Because 16bit seem to be more rare
2022-01-18T01:29:35 < zyp> eh, the ddr memory width doesn't really have a strong relation to the internal bus widths in any case
2022-01-18T01:30:08 < zyp> I believe you'll in any case access the memory in bursts wider than the internal bus
2022-01-18T01:30:59 < zyp> if this is FPGA stuff, you're probably also using geared IO, running the memory faster than the internal logic
2022-01-18T01:31:56 < zyp> I haven't done anything with ddr3 yet, but I've got a board with a 200MHz hyperram hooked to a fpga
2022-01-18T01:33:24 < zyp> the 8-bit hyperbus running at 200MHz ddr is translated into an internal 32-bit bus running at 100 MHz; four times slower and four times wider, so exactly the same throughput
2022-01-18T01:36:37 <@karlp> zyp: you can do this, with the mmio helper gdb (gdb) p /x *$mmio_ptr(RTC)
2022-01-18T01:36:42 <@karlp> but how do you _set_ ?
2022-01-18T01:37:05 <@karlp> (gdb) set *$mmio_ptr(RTC)->ISR |= (1<<6)

2022-01-18T01:37:38 < zyp> I guess
2022-01-18T01:37:50 < zyp> I tend to just use p/x for setting too
2022-01-18T01:38:08 < zyp> it just evaluates the expression and assignments are also expressions
2022-01-18T01:38:15 <@karlp> oh, right, I guess that works too.
2022-01-18T01:38:18 <@karlp> I've always used set :)
2022-01-18T01:38:46 < zyp> I'm just too lazy to switch the command, I print stuff first and then just append = blah

2022-01-18T01:39:25 < zyp> I seem to recall you need to do «set variable» or something

2022-01-18T01:42:46 <@karlp> I've tried printing it and using "call" but nothing seems to quite work)
2022-01-18T01:43:35 <@karlp> (gdb) p /x *$mmio_ptr(RTC->WPR) = 0xca
2022-01-18T01:43:45 <@karlp> using your styl of p for setting doesn't work either?

2022-01-18T01:45:19 <@karlp> of courset hat makes sense reading it, to unwrap the mmioptr
2022-01-18T01:45:28 <@karlp> c++ always does this to me, I cna read it, but can't write it to save my life
2022-01-18T01:45:29 < zyp> yeah, I wish gdb wasn't dumb as fuck
2022-01-18T01:46:37 < zyp> I had a nice xmethods-based solution to this, xmethods just fucking doesn't work on objects with the this-pointer optimized out
2022-01-18T01:48:08 < zyp> the method doesn't need the this-pointer, just the members of the object, which gdb is perfectly able to resolve, as evidenced by the $mmio_ptr() shit
2022-01-18T01:48:38 <@karlp> thanks fo rthe pointers, I'll try and save some notes...

2022-01-18T01:48:54 < zyp> the xmethods shit would handle operator-> so that you could just write p/x RTC->WPR
2022-01-18T01:49:15 < zyp> but gdb refuses to try that when RTC has no this
2022-01-18T01:49:58 < zyp> one day I'm gonna figure out how gdb does xmethods resolving and patch out that restriction

2022-01-18T11:48:29 < jpa-> i assume the answer is no because the counter hardware can probably only increment / decrement by one per cycle

2022-01-18T14:42:52 < zyp> haha
2022-01-18T14:45:10 < ventYl_> something about how C++ and Cmake are integrated into vscode makes me confused
2022-01-18T14:45:26 < ventYl_> it happens to be doing what it shouldn't and not doing, what it should
2022-01-18T14:46:59 < karlp> sounds like cmake...
2022-01-18T14:47:17 < ventYl_> apparently it is vscode itself
2022-01-18T14:47:32 < jpa-> sounds like computer
2022-01-18T14:47:41 < ventYl_> like, I just ran cmake in new binary directory, vscode re-runs it. not because it has, just because it wants to
2022-01-18T14:48:08 < ventYl_> it also runs build before I start debugging after vscode was started each time regardless of if anything changed or not
2022-01-18T14:48:21 < ventYl_> not just build, it runs cmake
2022-01-18T14:48:23 < ventYl_> then build
2022-01-18T14:48:27 < ventYl_> then starts debugger
2022-01-18T14:48:28 < jpa-> how does one know when to rerun cmake?
2022-01-18T14:48:56 < zyp> one does not simply rerun cmake
2022-01-18T14:49:06 < ventYl_> if your build system is sound, cmake will take care of this itself
2022-01-18T14:49:23 < ventYl_> you just run build, if cmake re-run is needed, it will run automagically
2022-01-18T14:49:34 < jpa-> what if it has never been run yet?
2022-01-18T14:49:44 < ventYl_> the thing is, that precondition almost never holds
2022-01-18T14:49:58 < ventYl_> jpa-: then your build directory is most probably empty and you know that :)

2022-01-18T14:55:38 < ventYl_> i think that the argumentation there is false
2022-01-18T14:56:07 < ventYl_> in certain cases it is clear that vscode checks the ZERO_CONFIG (?) target of CMake, which tells you if CMake re-run is needed or not
2022-01-18T14:56:53 < ventYl_> but here it deliberately runs CMake even though I am pretty sure, it is not needed (I ran CMake manually and built the SW outside of VScode)
2022-01-18T14:58:49 < karlp> I would imagine vscode chose it's own build dir...
2022-01-18T14:59:04 < ventYl_> nope, it is using the one I used
2022-01-18T14:59:21 < ventYl_> actually, I planted build into VScode's build directory manually

2022-01-18T15:04:56 < ventYl_> what the fuck is going on inside that pile of dried camel shit?

2022-01-18T15:05:35 < ventYl_> this project together with vscode and windows is gone in two weeks

2022-01-18T16:17:41 < PaulFertser> I think UK politics is mostly a bad comedy show, it's all about bla-bla-bla and populism rather than discussing real matters.
2022-01-18T16:18:21 < qyx> not much different anywhere else
2022-01-18T16:20:16 < PaulFertser> Plus they have a special place for silly stand-ups , where they have fun cursing each other constantly inventing new ways for that because older ways become "unparliamentary language" after a while.
2022-01-18T16:21:11 < BrainDamage> the things that bother me is that the uk has an unhealthy obsession with surveillance
2022-01-18T16:21:26 < BrainDamage> and its colonies, former or not share the same trait
2022-01-18T16:21:34 < drzacek> hello there
2022-01-18T16:21:58 < drzacek> am reading the UM2206, nucleo -p document, and I'm not sure if I understand correctly
2022-01-18T16:22:45 < drzacek> it has the smps, not sure why it needs to be such an important feature, it's the only alternative to ldo, but somehow by design it doesn't run on it's own to create stable voltage, in needs gpio from the nucleo board
2022-01-18T16:22:58 < PaulFertser> Guess UK people think CCTV is the answer to street violence. Somehow other countries manage it sensibly while despite all the cameras Londoners can be gotten robbed of their motor bikes at any moment.
2022-01-18T16:23:12 < drzacek> so if I understand correctly, I just CAN'T use those pins, that are predefined in stm32cubeide project for nucleo -p board?
2022-01-18T16:23:21 < drzacek> need to leave them as they are
2022-01-18T16:23:33 < drzacek> OR IS there a way to actually use those pins?
2022-01-18T16:29:18 < jpa-> drzacek: which pin are you talking about?
2022-01-18T16:29:24 < drzacek> https://imgur.com/a/KC5h7d9
2022-01-18T16:29:33 < drzacek> pa4-pa7
2022-01-18T16:29:51 < BrainDamage> they are hardwired to the SMPS and connector CN11, but there's a jumper too
2022-01-18T16:30:08 < BrainDamage> without the actual schematic it's difficult to say if you can bypass the SMPS connection
2022-01-18T16:30:34 < BrainDamage> if you cannot, then no, you can't repourpose the pins without fucking up the voltage config
2022-01-18T16:30:42 < jpa-> they probably have the schematic downloadable somewhere
2022-01-18T16:31:31 < drzacek> https://www.st.com/resource/en/user_manual/um2206-stm32-nucleo64p-boards-mb1319-stmicroelectronics.pdf
2022-01-18T16:31:50 < drzacek> damn, those are the SPI pins
2022-01-18T16:31:55 < drzacek> I need them bad
2022-01-18T16:32:06 < jpa-> did you check the schematic?
2022-01-18T16:35:09 < drzacek> beside that whats shown in manual I can't find any
2022-01-18T16:36:58 < drzacek> if I see it correctly, it CAN be configured via solder bridges
2022-01-18T16:37:02 < drzacek> damn
2022-01-18T16:37:26 < drzacek> ugh, I guess it just be easier to solder different spi pins to my shield
2022-01-18T16:38:03 < jpa-> https://www.st.com/resource/en/schematic_pack/mb1319-l433rcp-c01.pdf  on the st site
2022-01-18T16:39:04 < BrainDamage> drzacek: the schematics are under the 'cad resources' section, not docs
2022-01-18T16:40:56 < BrainDamage> there's bridges you can cut
2022-01-18T16:41:20 < BrainDamage> sb 92 89, 93, 88
2022-01-18T16:41:35 < BrainDamage> in sheet 7
2022-01-18T16:42:03 < BrainDamage> that'll detach the stm32 from the smps controller
2022-01-18T16:42:13 < drzacek> ah there it is
2022-01-18T16:42:15 < BrainDamage> but it'll also detach them from the external power connector
2022-01-18T16:42:33 < drzacek> meaning?
2022-01-18T16:43:08 < BrainDamage> if they aren't accessibly to the pin header strip, you'll have to solder yourself a wire to one side of the bridge
2022-01-18T16:44:28 < BrainDamage> ok, they are available on CN6
2022-01-18T16:44:40 < BrainDamage> so no soldering necessary
2022-01-18T16:44:50 < drzacek> page 6 of the schematic, bottom
2022-01-18T16:45:02 < drzacek> is that the smps? 
2022-01-18T16:45:19 < drzacek> looks like pg is not connected and enable is on Vin, no gpio pins involved?
2022-01-18T16:45:56 < BrainDamage> no, it's on page 7
2022-01-18T16:46:37 < BrainDamage> a smps ( barrying few rare exception with integrated coils ), need external coils
2022-01-18T16:47:23 < drzacek> what exactly is JP8 doing? "VDD_in_SMPS"? powering the smps, so no jumper, smps dead - but what's the point, what is powering the mcu then?
2022-01-18T16:48:44 < BrainDamage> the external power connector
2022-01-18T16:50:14 < drzacek> aka through gpio/morpho pin?

2022-01-18T16:56:11 < drzacek> okay, so the ENABLE signal can be removed, if I cut the bridge coming from gpio, and bridge the one coming from Vin. but that's PA4, which I don't need, so I can leave it. 
2022-01-18T16:56:45 < drzacek> the SMPS_V1 seems to be going to U12 only, which I don't have, only U11, so can be simply removed from the cubemx project without problems? 
2022-01-18T16:57:46 < drzacek> but the _PG and _SW pins doesn't seem to have any usable bridges to pull up/down the signals
2022-01-18T16:58:05 < drzacek> meh, fail. gonna resolder the spi signals to the shield, it's gonna be easier than this

2022-01-18T18:32:27 < tct> yeah, that´s pretty standard procedure
2022-01-18T18:33:14 < tct> unfortunately it happens more often than not that some metal parts find their way into the hay / feeding stock
2022-01-18T18:33:35 < tct> we used to screen before feeding it to the cows but shit just happens

2022-01-18T18:46:10 < tct> Steffann, doing okay - how about you?
2022-01-18T18:46:17 < Steffann> Did you catch the covid yet?
2022-01-18T18:46:26 < tct> nope - still 100% covid free :D
2022-01-18T18:46:29 < Steffann> I'm OK too, not perfect, not  bad.

2022-01-18T21:00:57 < BrainDamage> he just call it hyperloop because at this point his brain can't even disambiguate it
2022-01-18T21:01:31 < ventYl_> i still think it is a project with completely unrealistic goals
2022-01-18T21:02:01 < BrainDamage> that's on brand for laurenceb
2022-01-18T21:02:40 < ventYl_> I mean, why does country with such defunct and obsolete railway network need something like hyperloop?
2022-01-18T21:03:50 < BrainDamage> I guess they want to start over with something new, it's not like it's compatible with existing rail network so it'd be a competitor anyway

2022-01-18T21:13:04 < ventYl_> so, completely different than opel GT?
2022-01-18T21:13:17 < ventYl_> ah yes,
2022-01-18T21:13:25 < ventYl_> opel GT had orthodox conception
2022-01-18T21:13:49 < qyx> our opel may become disassembled soon too

2022-01-18T21:16:52 < catphish> i'm always puzzles, when americans, and others say "oil change" do they mean a standard routine service? or are people literally just changing oil?

2022-01-18T21:18:57 < catphish> well the vx220/speedster seems like a good car, essentially because it's just a lotus elise with a basic GM engine in it, not much to go wrong i guess
2022-01-18T21:19:26 < ventYl_> that car had a shitload of problems with engine
2022-01-18T21:19:29 < catphish> ventYl_: every car i've ever owned has a standard service routine, oil change is one part of it, but you'd never do it in isolation
2022-01-18T21:19:41 < catphish> opel gt, or the one i have?
2022-01-18T21:19:46 < ventYl_> GT
2022-01-18T21:19:52 < ventYl_> it had some 2.0l turbocharged engine
2022-01-18T21:19:59 < catphish> that makes sense
2022-01-18T21:20:04 < kakium69> catphish: you can change just oil though
2022-01-18T21:20:22 < catphish> kakium69: i'm sure you *can*, and that was kinda my question
2022-01-18T21:20:37 < catphish> when people say they're getting an oil change, what do they mean an oil change
2022-01-18T21:20:44 < catphish> or do they mean a service?
2022-01-18T21:20:58 < ventYl_> once, it went into shop literally just for oil change. later that day workshop manager called my boss that car needs to stay there a bit longer because there was some minor problem found during service check. and in the end it stayed there for two months, because somehow, during maintenance "wiring loom got broken"
2022-01-18T21:21:05 < ventYl_> and the closest available wiring loom was in the US
2022-01-18T21:21:26 < kakium69> catphish: oil change + oil filter
2022-01-18T21:21:28 < ventYl_> while the car was still under warranty, I assume that workshop was trying to kill it
2022-01-18T21:21:44 < ventYl_> to get rid of all the problems it caused to them
2022-01-18T21:22:05 < catphish> afaik no garage here would ever do less than oil, oil filter, air filter, check fluids, check brake wear as standard
2022-01-18T21:22:20 < catphish> and ideally, whatever other random stuff the specific car recommends
2022-01-18T21:22:32 < catphish> ventYl_: lol
2022-01-18T21:22:52 < catphish> ventYl_: this one is a 2.2l NA, only 140HP from 2.2l!
2022-01-18T21:23:08 < ventYl_> mine has 133HP from 2.3
2022-01-18T21:23:46 < catphish> by comparison, my wife's VW gets about 190HP from 1.4l :)
2022-01-18T21:24:06 < ventYl_> but one wrong parking may cause engine disintegration
2022-01-18T21:24:46 < ventYl_> catphish: just out of curiosity, what kind of cells did you settle with for your EV conversion?
2022-01-18T21:24:52 < catphish> supercharger+turbocharger, it's a lovely engine, and the ridiculous sports exhaust installed by a previous owner really makes it souns like a much larger engine
2022-01-18T21:25:20 < ventYl_> I am toying with idea of buying old fiat 500e and replacing it's battery cells with something new (which is completely illegal in this country)
2022-01-18T21:25:52 < catphish> ventYl_: these things - https://i.imgur.com/NovoA2j.jpg - 1.5kWh, 16S, integrated BMS
2022-01-18T21:26:35 < ventYl_> catphish: what are approximate dimensions?
2022-01-18T21:26:43 < catphish> opel gt would make a lovely EV :)

2022-01-18T21:27:40 < ventYl_> 500e module is ~175x125x270 mm

2022-01-18T21:32:30 < ventYl_> is it using pouch cells?

2022-01-18T21:53:38 < kakium69> to the junkyard or there is organized crime behind it collecting cats to shipping containers
2022-01-18T22:01:48 < catphish> kakium69: the value of the cats is precious metals, i assume they are easily recycled
2022-01-18T22:02:06 < kakium69> yes
2022-01-18T22:02:19 < catphish> no idea how that works though
2022-01-18T22:02:30 < kakium69> you won't have problems getting container full of cats out of your hands
2022-01-18T22:03:15 < ventYl_> catphish: i've heard that those old cats were full of platinum, so even worn out one will still have sufficient platinum left to actually be valuable
2022-01-18T22:04:46 < catphish> ventYl_: yeah, i believe that's the case, i have cut mine out of the exhaust and will try to sell it

2022-01-18T23:56:47 < PaulFertser> I think in russia more women than men solder for living, professionally.
2022-01-18T23:59:48 < BrainDamage> welding too? because I've met quite a few woman welders from russia here
--- Day changed Wed Jan 19 2022
2022-01-19T00:01:16 < PaulFertser> No, I think more welders are men, working on building sites. There were quite a few female crane operators in the USSR times, not sure how it is now.

2022-01-19T00:06:49 < zyp> how old do I need to wait for my kid to become before I teach her welding?
2022-01-19T00:07:36 < zyp> and should I just get her started on TIG right away, or step through stick and MIG first?
2022-01-19T00:08:17 < kakium69> mig
2022-01-19T00:08:52 < zyp> sounds good, that's the only one I've got
2022-01-19T00:08:55 < BrainDamage> I guess if she can write she's sufficiently dextrous to handle a welder
2022-01-19T00:09:14 < PaulFertser> You can stick a stick into MIG too I think.
2022-01-19T00:09:35 < zyp> maybe it'd be good to do soldering first
2022-01-19T00:09:45 < PaulFertser> Xogium: how are you feeling today?
2022-01-19T00:11:22 < PaulFertser> I think soldering is just not as impressive bright active loud process and it's hard to brag about it.
2022-01-19T00:12:04 < zyp> perhaps
2022-01-19T00:12:30 < zyp> she's still only two, so I guess it'll still be a while :p

2022-01-19T00:20:15 < BrainDamage> does she write things on the computer?
2022-01-19T00:20:18 < zyp> kakium69, so I hear
2022-01-19T00:20:48 < kakium69> parameters need to be spot on and there are many
2022-01-19T00:20:49 < Xogium> we'll have to work on that, but we're thinking that tracing shapes in the palm of the hand would work relatively ok at least for simple things
2022-01-19T00:20:53 < zyp> I've been wanting a tig welder, not because I have something specific to weld, but because I want to try it :p
2022-01-19T00:20:58 < kakium69> also work pieces need to be clean
2022-01-19T00:21:26 < Xogium> otherwise yeah computer message
2022-01-19T00:21:31 < zyp> but I need an actual project to justify it
2022-01-19T00:21:55 < kakium69> I have tig
2022-01-19T00:22:10 < BrainDamage> zyp: like every parent in the world, 'teaching your kid' is the perfect excuse
2022-01-19T00:22:10 < kakium69> I have used it like once
2022-01-19T00:22:27 < BrainDamage> and you can't teach her unless you have good practice yourself, so might want to get a headstart
2022-01-19T00:22:34 < kakium69> also: tig welding is expensives too
2022-01-19T00:22:44 < Xogium> honestly, its been the 3rd specialist of the ear I go to, and all of them come back meniere's disease
2022-01-19T00:22:45 < kakium69> that argon hmm.. pricey
2022-01-19T00:23:16 < BrainDamage> Xogium: do you tell them about meniere, or do you let them come to their own conclusions?
2022-01-19T00:23:21 < kakium69> did 20litre cylinder just by fooling with the machine
2022-01-19T00:23:23 < zyp> kakium69, that goes for MIG as well
2022-01-19T00:23:59 < kakium69> you can go with even full CO2 with mig
2022-01-19T00:24:00 < zyp> although IME it's not the gas that's expensive, it's just having a cylinder
2022-01-19T00:24:09 < Xogium> I avoid telling them, honestly. I didn't know what was going on at the first specialist, but even when he diagnosed me with meniere's, I didn't tell the others
2022-01-19T00:24:17 < Xogium> to not influence what they would say
2022-01-19T00:24:38 < BrainDamage> yeah, that's the best way to approach it
2022-01-19T00:25:37 < Xogium> I mean what's the chance I get the same response 3 times, and yet it would be nothing like it ?
2022-01-19T00:26:11 < Xogium> they did tons and tons of tests, hearing tests, checked my blood, looked for infections
2022-01-19T00:26:17 < Xogium> there's nothing
2022-01-19T00:26:49 < zyp> in norway you apparently get scheduled for MR if they suspect meniere
2022-01-19T00:27:01 < Xogium> I'm getting bad at those hearing tests… I confuse the tinitus with the tones they play at random
2022-01-19T00:27:23 < PaulFertser> "If you jave a CV machine, you CAN stick with it. It will have enough drop to give at least a little control, but will likely be much less forgiving than a machine designed for CC"

2022-01-19T00:29:36 < kakium6967> and you could also use stick welder as tig welder but lack ignition and gas valve

2022-01-19T00:30:16 < kakium6967> not worth it

2022-01-19T00:48:11 < fenugrec> TIG  with DC almost always does an HF start, but some welders do "scratch-start" where they detect electrode contact but don't run full power until after the circuit opens, so you don't weld your tungsten to the workpiec
2022-01-19T00:48:14 < karlp> the homebrew community went trhough a bunch of hoops with gas vendors finding who'd just refill occasioanlly, and test bottles, instead of the big vendors who don't even charge fro gas, just charge per bottle/month

2022-01-19T00:48:44 < fenugrec> welding gas cylinders is a total racket around here
2022-01-19T00:48:57 < fenugrec> you better have deep pockets, run a show, or know a guy
2022-01-19T00:49:01 < fenugrec> run a *shop
2022-01-19T00:49:03 < zyp> karlp, yeah, I rented a bottle for a couple of years before when I dicked around with MIG
2022-01-19T00:49:19 < karlp> what's the difference between tig and mig again? I've only done mig, a couple of times years ago
2022-01-19T00:49:40 < zyp> but nowadays there's decent options for buying a smaller bottle that you trade in to get a refill
2022-01-19T00:49:57 < fenugrec> TIG is more like electronic soldering, you have a tungsten "pencil" maintaining the arc and you manually feed in filler metal
2022-01-19T00:49:59 < kakium6967> unless you are into motorsport as in custom vehicles or build process tanks and pipes from stainless there is very little to do with tig
2022-01-19T00:50:57 < zyp> yeah, TIG is pretty much arc soldering
2022-01-19T00:50:58 < fenugrec> I like TIG for the ability to see what's going on and gauge heat input before it's too late. it's super nice for thin stuff. But it's unforgiving with less than super clean base metal
2022-01-19T00:51:36 < zyp> and while I haven't tried it, I have the impression you have more control of what you're doing than with MIG
2022-01-19T00:51:38 < karlp> also, fuckin what is wrong  with my rtc init?!
2022-01-19T00:51:49 < kakium6967> you do TIG weldings fenugrec?

2022-01-19T00:52:34 < fenugrec> kak, yes I have two tig machines, and very very little experience with mig so I'm biased
2022-01-19T00:52:46 < kakium6967> oh
2022-01-19T00:53:06 < fenugrec> but for anything automated, thick, or semi-clean, mig is king
2022-01-19T00:53:17 < kakium6967> or anything quick
2022-01-19T00:53:32 < fenugrec> yes
2022-01-19T00:53:36 < kakium6967> anything mild steel
2022-01-19T00:53:45 < fenugrec> well stick, if you're not a complete moron like me, could be pretty cool too
2022-01-19T00:54:03 < fenugrec> you can weld outside in the wind with stick, unlike tig/mig
2022-01-19T00:54:10 < kakium6967> in rain even
2022-01-19T00:54:21 < fenugrec> eh, metal better be dry

2022-01-19T00:54:35 < fenugrec> ah yes. And through paint, too
2022-01-19T00:55:05 < kakium6967> that rust thing is fun about stick
2022-01-19T00:56:05 < kakium6967> it can take a while of banging and scraching to get it light up but then it just ploughs through
2022-01-19T00:56:12 < fenugrec> heh
2022-01-19T00:56:44 < kakium6967> had to go to doctor last time I used stick

2022-01-19T11:20:53 < drzacek> why the hostility. stm32cubeide is offered officialy on windows, it works, so it isn't a windows issue, it is a very specifice cubeide issue
2022-01-19T11:21:15 < drzacek> and just because it said "dll error" (what it ever means) doesn't mean it's windows error
2022-01-19T11:21:46 < drzacek> it is obviously a problem with the firmware on the stlink, maybe it couldn't initialize properly, or had communication problems, or wasn't properly detected
2022-01-19T11:21:58 < drzacek> either way, was solved by upgrading the firmware in different tool
2022-01-19T11:26:29 < ventYl_> dll error most probably leads to something in cuba being fucked up for windows port

2022-01-19T11:34:28 < karlp> I used it in java, but it has generators for c/python/go/blah/whatever,
2022-01-19T11:34:37 < karlp> you get objects with the parse results ready to go,
2022-01-19T11:35:46 < karlp> it's like "write language spec, interactively test with gui tools, press generate button, call generated_parser.parse(myinput) => parsedObject, use parsedObject as you see fit...."
2022-01-19T11:38:15 < karlp> and then you can skip all your own error prone string splitting and tokening and state machines
2022-01-19T11:39:05 < ventYl_> hm, I wonder how useful/bloated would a flex/bison generated parser be
2022-01-19T11:39:21 < karlp> for what?
2022-01-19T11:39:29 < ventYl_> marshalling
2022-01-19T11:39:30 < karlp> antlr is just like flex/bison but more modern
2022-01-19T11:39:47 < karlp> I mean, plenty of tools use flex/bison/yacc already, so... useful I guess?
2022-01-19T11:39:59 < ventYl_> that pretty much answers my question
2022-01-19T11:40:32 < ventYl_> i've ever used flex/bison only for full-blown language processing, thus I don't have clue on how bloaty the generated code is, if you parse something reasonably small, such as wire protocol
2022-01-19T11:43:58 < karlp> you can find some old commentary that flex/bison/yacc are easier to develop grammars for, but the generatd code is "heirglypics" and antlr is a little harder to write grammars for, but generates nicer code.
2022-01-19T11:44:16 < mawk> bison generates ugly jump tables
2022-01-19T11:44:22 < mawk> don't look at the generated code
2022-01-19T11:44:23 < karlp> it might be worth pointing out that antlr v4 is kinda "more" than old antlr2/3: https://github.com/antlr/antlr4/blob/master/doc/faq/general.md
2022-01-19T11:45:08 < karlp> some of the points there outweight some earlier "bison et all can do left recursive, and antlr can't! antlr sucks!" claims
2022-01-19T11:45:10 < ventYl_> i did once, found out that I don't understand simplified chineese. I won't do that again
2022-01-19T11:46:21 < karlp> like, some of the highly voted "comparing antlr/bison/et al" on stack overflow are from _2011_ and antlr has moved on a lot since then
2022-01-19T11:46:54 < ventYl_> result of it's run is pure source code, with no third party?
2022-01-19T11:47:04 < ventYl_> it may be relevant for me soon
2022-01-19T11:47:18 < ventYl_> one project wants to get rid of protobuf
2022-01-19T11:48:05 < karlp> yeah, antlr is not a runtime dep, only generation time.
2022-01-19T11:48:14 < ventYl_> cool

2022-01-19T11:48:35 < mawk> https://capnproto.org/
2022-01-19T11:48:40 < karlp> Ive _no_ experience doing binary grammars in antlr though, 
2022-01-19T11:48:41 < ventYl_> in this particular use case, having a dependency on protobuf causes a lot of trouble
2022-01-19T11:48:45 < karlp> it may be easy, it maybe gross
2022-01-19T11:49:28 < zyp> ventYl_, so basically NIH? :p

2022-01-19T11:49:54 < mawk> it's like protobuf but smaller
2022-01-19T11:50:00 < mawk> with a funny website
2022-01-19T11:50:26 < ventYl_> oh, the problem is not in how protobuf works, it's pure existence is a problem
2022-01-19T11:50:50 < ventYl_> as this project is integrated in variety of other projects, so having dependencies causes integration problems
2022-01-19T11:52:06 < mawk> it's not the first time a lib has lib dependencies
2022-01-19T11:52:13 < mawk> maybe these other projects need to not be lazy

2022-01-19T16:03:17 < ventYl_> still not as good as my most beloved imperial system unit

2022-01-19T16:07:56 < karlp> what's gpm/sf?
2022-01-19T16:08:10 < karlp> gallons per mile / square foot?
2022-01-19T16:08:44 < Xogium> imperial units are just so weird
2022-01-19T16:08:56 < karlp> gallons per minute / square foot? flow rate normalized to cross sectional area?
2022-01-19T16:09:18 < karlp> is that == velocity of fluid?

2022-01-19T16:19:47 < ventYl_> karlp: right and right
2022-01-19T16:20:10 < ventYl_> latter is flow rate per area of solar collector
2022-01-19T16:21:18 < karlp> the flowmeters I've used just had m³, m³/s or m/s... depending on volume, volume flow or velocity
2022-01-19T16:21:55 < karlp> or at least, that's all I used, it ahd options for all sorts of bullshit including putting in multiplers to get "BTU" and shit out, if I told it wht sort of fluid it was but fuck those units
2022-01-19T16:22:04 < karlp> that's a front end presentation job :)
2022-01-19T16:22:08 < fenugrec> My favourite unit is the foot-lambert, probably a close relative to ftcd
2022-01-19T16:22:54 < fenugrec> karlp, thanks, yea just looking for basic examples to get a feel for what it can do. No immediate need for such but it sounds like a good tool to have handy
2022-01-19T16:22:59 < karlp> 1/pi candla/sqft,
2022-01-19T16:23:03 < karlp> that is pretty special :)
2022-01-19T16:23:23 < BrainDamage> grains per cubic foot
2022-01-19T16:23:37 < fenugrec> hogshead per furlong
2022-01-19T16:23:56 < BrainDamage> what I said is used in practice unfortunately
2022-01-19T16:25:18 < karlp> grains as in gemstones/explosives?
2022-01-19T16:25:33 < karlp> what is grains/ft³ used in?
2022-01-19T16:25:50 < BrainDamage> weapon ammunition loading

2022-01-19T16:27:10 < karlp> gr/dscf oh, that's used in stupid pollutant measure too.
2022-01-19T16:27:15 < karlp> fuck that.
2022-01-19T16:27:26 < karlp> proof is dumb, but at least it's just 2*ABV

2022-01-19T19:12:21 < karlp> if I touch whitespace on a blank line.... it recompiles the cpp file, but _doesn't_ relink the .elf?

2022-01-19T19:36:34 < mawk> but I don't think it counts as picking
2022-01-19T19:36:51 < PaulFertser> Yes, not a non-destructive entry indeed. But how can that fail?
2022-01-19T19:36:58 < PaulFertser> Fake screwdriver?
2022-01-19T19:37:05 < JohnRambo> too small hammer

2022-01-19T20:50:37 < karlp> so, it's not buggy st code, just wildly odd st code.  which at least makes more sense, I couldn't believe it could actually be broken...
2022-01-19T20:51:40 < karlp> (same code applies to all Lx parts and WB) I was looking at https://github.com/STMicroelectronics/stm32l1xx_hal_driver/blob/9ee84a7ac1b901fbe57f167a4bd2ae0b2d95c4fb/Inc/stm32l1xx_ll_system.h#L623  and the "LINE & 0x3" just made no sense with how the exti's are defined in the ref man. 
2022-01-19T20:52:07 < karlp> because I naiively assumed that "lines" were 0..16 and ports were 0..x as well, 
2022-01-19T20:52:09 < karlp> but no!
2022-01-19T20:52:46 < karlp> rather than just shifting the 0..16 line to select the right EXTICR reg, like other libraries do, they just encode it into the magic params you have to use: https://github.com/STMicroelectronics/stm32l1xx_hal_driver/blob/9ee84a7ac1b901fbe57f167a4bd2ae0b2d95c4fb/Inc/stm32l1xx_ll_system.h#L146-L161

2022-01-19T20:59:29 < bitmask> i dont know why so many people like those
2022-01-19T20:59:36 < bitmask> samoas are the best
2022-01-19T20:59:48 < bitmask> i considered getting just those :P

2022-01-19T21:45:17 < qyx> samoas? are they the same as samas?
2022-01-19T21:45:23 < qyx> and samds
2022-01-19T21:45:32 < qyx> sry stupid joke
2022-01-19T21:54:31 < zyp> < karlp> if I touch whitespace on a blank line.... it recompiles the cpp file, but _doesn't_ relink the .elf?
2022-01-19T21:54:35 < zyp> yes, this is normal
2022-01-19T21:56:20 < zyp> scons not only looks at file timestamps like make, but also checksums every file, so it'll skip the linking step if every .o file is unchanged
2022-01-19T21:57:03 < zyp> debug info contains line numbers, so changing whitespace on a line doesn't affect the compiler output, but adding or removing lines of whitespace does
2022-01-19T22:40:54 < karlp> zyp: right, but it _is_ relinking if I change whitespace inside an operator, which shouldn't have made any difference.
2022-01-19T22:42:40 < karlp> https://paste.jvnv.net/view/ik84A
2022-01-19T22:43:19 < karlp> still not my real problem, just something I noticed while paranoid about ohter things
2022-01-19T22:43:23 < zyp> maybe debug info not only contains line nums but also col of that call following the whitespace?
2022-01-19T22:44:12 < zyp> it doesn't really matter much what it is, the point is that scons is smart enough to figure out whether the input changed or not
2022-01-19T22:44:18 < jpa-> that would be my guess too
2022-01-19T22:44:22 < karlp> yeah, I just had trust issues :)
2022-01-19T22:45:01 < karlp> been having a rough day with tantrum children and zero success with sw, no matter how far I keep stripping things back, just going a bit insane :)

2022-01-19T22:47:29 < karlp> but perhaps not dumping enough info :)
2022-01-19T22:47:48 < jpa-> scons checks hash of file
2022-01-19T22:47:48 < karlp> debug ifno is other sections I guess

2022-01-19T22:50:10 < karlp> changing the whitespace in other places doesn't change that.

2022-01-19T22:53:54 < karlp> in other news, gpios in laks have "n" as private, I've added a getter, but is that good style?  can we have something that gets the "port" out as well?
2022-01-19T22:54:22 < karlp> jpa-: I'm kinda feeling like I'm pretty much out of abstractions right now, shit just doesn't work.
2022-01-19T22:55:54 < jpa-> did you set the "select port where exti line comes from" register?
2022-01-19T22:56:11 < karlp> yeah, that's where I was chasing the st code earlier.
2022-01-19T22:56:21 < karlp> I've got a st cube example, looks like mine.
2022-01-19T22:56:28 < karlp> can't really see where I'm going wrong, but will get there :|
2022-01-19T22:57:20 < karlp> only thing st does is nvic prior grouping init, but I'venever needed to set that explicitly anywhere else, and it's only changing the groupings, so I refuse to touch that
2022-01-19T22:57:54 < karlp> anyay, for all thei screaming, they're asleep now, so I can work on it a bit longer.
2022-01-19T22:58:15 < jpa-> is the exti flag getting set?

2022-01-19T22:59:38 < zyp> karlp, I'd be kinda inclined to just change the gpio and number members to be public, but if you do you should change n to be const as well
2022-01-19T22:59:44 < Laurenceb> idiot junior manager just removed all the earthing system from the design then submitted the documentation to the client

2022-01-19T23:00:08 < Laurenceb> Steffann: its crazy fast and it works... almost
2022-01-19T23:00:31 < Laurenceb> now junior manager refuses to accept he did anything wrong
2022-01-19T23:00:57 < zyp> karlp, but feel free to do whatever makes sense to you, I can always refactor it later anyway
2022-01-19T23:01:13 < karlp> zyp: yeah, personalyl I'm more of a "we don't really need getters"  sort of person :)
2022-01-19T23:01:21 < karlp> getting the port "number" out of a port is a little different though.
2022-01-19T23:01:34 < Steffann> Isnt it easy? You go to your version control, check which document was reviewed, see it changed after review/acceptance and you blame him, Laurenceb 
2022-01-19T23:01:47 < Laurenceb> >version control
2022-01-19T23:01:49 < Laurenceb> lmao

2022-01-19T23:02:40 < Laurenceb> little bastard can spew buzzword bingo for literally hours at anyone who criticizes him
2022-01-19T23:02:54 < zyp> karlp, most reasonable way to get the port number is probably to simply store it in the STM32_GPIO_v*_t
2022-01-19T23:03:25 < Laurenceb> apparently its "not proven to impact safety"....
2022-01-19T23:03:55 < karlp> yeah, at construction time, just not sure right way of doing that :)
2022-01-19T23:04:32 < zyp> I guess the right way would be to add it as another parameter to the yaml
2022-01-19T23:05:14 < zyp> add a member and a constructor to the class initializing it, then update the SConscript to pass in the extra argument
2022-01-19T23:05:55 < kakium69> Laurenceb: why did he remove earthing system?
2022-01-19T23:06:06 < kakium69> there was a problem so he removed the problem?
2022-01-19T23:06:12 < karlp> yeah, the yaml seemed like where it would have to go.
2022-01-19T23:06:19 < karlp> i've left it off for now :)
2022-01-19T23:07:45 < zyp> the other way to get the port number would be to calculate the difference between address of current port and GPIOA, divided by 0x400 or what the instance interval is, but that's kinda dirty
2022-01-19T23:07:57 < karlp> yeah, I don't like that honestly.
2022-01-19T23:08:05 < karlp> it's a lot of magic for not a lot of gain...
2022-01-19T23:08:40 < Laurenceb> kakium69: he thought it would save money and make it easier to install
2022-01-19T23:11:49 < kakium69> he has no idea what he is doing?
2022-01-19T23:13:15 < jpa-> (port >> 10)&15 -5  
2022-01-19T23:29:15 < karlp> yarh, except I'm not c++ enough to get the port address back out and keep the casting happy :)
2022-01-19T23:32:51 < karlp> ok, maybe I am: https://paste.jvnv.net/view/zQwqH
2022-01-19T23:33:31 < karlp> the -5 isn't required on ... this platform at least...

2022-01-20T12:12:57 < karlp> does this mean you are using 4uA/MHz? https://bin.jvnv.net/file/uTzWZ.png  
2022-01-20T12:13:16 < karlp> the adc section of the ref man just says that it has a "dual clock domain architecture"
2022-01-20T12:13:49 < karlp> and can be clocked from either [syscock|pllsai] _or_ the AHB clock.
2022-01-20T12:13:55 < karlp> neither of those sound like "independent"
2022-01-20T12:14:34 < karlp> or do they mean that if you are using the [sysclock|pllsai] you are using the "independent clock domain" figure, and if you are using the AHB clock, yhou are using the "clock domain" figure?
2022-01-20T12:16:34 < karlp> I mean, you still need the bus clock to get data out?
2022-01-20T12:16:42 < karlp> same thing  applies to usart/i2c/timers
2022-01-20T12:18:43 < karlp> hrm, on uart the descriptions might be a bit better
2022-01-20T12:19:14 < karlp> you have to have the independent clock running, but you can turn on the "not independent" bus clock when you get an event and then access the peripheral
2022-01-20T12:23:09 -!- Mangy_Dog [Mange@user/mangy-dog/x-7397214] has joined ##stm32
2022-01-20T12:25:26 < zyp> I would assume independent means it can run even when the bus clock is turned off
2022-01-20T12:26:07 < karlp> yeah, from reading the uart/i2c sections it looks like I can turn off the ahb adc, but still leave it running, and save those 2uA/Mhz.
2022-01-20T12:26:22 < karlp> what's annoying me now is that is adc can only run down to lprun,
2022-01-20T12:26:44 < karlp> to get low power then I want to run sysclock really slowly while I'm sitting in lprun, let the adc go to dma.
2022-01-20T12:26:52 < karlp> so far so good, adc has an independent clock, 
2022-01-20T12:27:06 < karlp> but the PLL is 200uA _minimum_ to have that independent clock
2022-01-20T12:27:18 < karlp> which is a pretttttty big chunk of budget :)
2022-01-20T12:27:36 < karlp> you saw my syscfg fix last night? "use the right base address" 
2022-01-20T12:27:44 < zyp> yeah
2022-01-20T12:35:53 < qyx> do you need PLL for intependent clock?
2022-01-20T12:36:20 < karlp> eithers either sysclock|pll, or ahb
2022-01-20T12:36:27 < karlp> and ahb is from sysclock implicitly...
2022-01-20T12:36:52 < zyp> sysclock doesn't have to come from pll, but I guess it's impractical not to :)
2022-01-20T12:37:22 < qyx> that's why I am asking
2022-01-20T12:37:23 < karlp> well, I was running sysclock straight from hse, because I don't need the extra 32mhz, (yet?) and wanted to save that 200uA,
2022-01-20T12:37:28 < qyx> I usually don't use PLL
2022-01-20T12:38:03 < qyx> my setup is usually either direct HSE or MSI&LSE FLL
2022-01-20T12:38:30 < karlp> but if sysclk is msi or hsi, or who cares at 500kHz to be "running, because we can't use stop modes and keep the adc running"  then I need the adc indepenentd clock to be "faster" and that means it has to be the pll, and that's immediately this 200uA again.
2022-01-20T12:38:55 < qyx> is the thing battery powered?
2022-01-20T12:39:09 < karlp> which I hadn't been accounting when I was doing my envelope calclations on how muych the ADC would draw
2022-01-20T12:39:22 < karlp> not even batteries, magic harvesting.
2022-01-20T12:40:15 < qyx> add more magic then!
2022-01-20T12:40:34 < karlp> yeah, tht's what I'm working on :)

2022-01-20T12:48:37 < qyx> karlp: how much SPS?
2022-01-20T12:49:29 < qyx> I am curious if the DMA is really helpful
2022-01-20T12:50:00 < qyx> instead of eg. doing stop0, wake up periodically, reconfigure clocks, sample, stop0 again
2022-01-20T12:50:44 < qyx> and there is the BAM which nobody knows what is it for
2022-01-20T12:50:51 < qyx> but probably exactly for this
2022-01-20T12:51:25 < karlp> I suspect my sps is too high for the stop/start, 
2022-01-20T12:51:45 < karlp> I _suspect_ just lpsleep with sysclock very low is easier, but thatmight b e an idea.
2022-01-20T12:51:53 < karlp> playing withthe cube power explorer thing 
2022-01-20T12:56:38 < qyx> hm, energy harvesting in iceland is easy, isn§t it?
2022-01-20T12:56:44 < qyx> just make it lava powered
2022-01-20T12:57:17 < karlp> hrm, I'd not even considered going to stop and restarting complerely for each individual adc sample.
2022-01-20T12:57:26 < karlp> that.... might.... actually be feasible.
2022-01-20T12:57:33 < karlp> fuckingcomplicated to setup though
2022-01-20T12:58:36 < benishor> hmmm, platformIO doesn't seem to "see" my stlink v2 at devices tab
2022-01-20T13:00:31 < karlp> fucking  hungary can't keep covid out of the handball
2022-01-20T13:01:00 < karlp> we're doing super well, and now captain, goalie, and two others all have covid
2022-01-20T13:01:07 < karlp> german team has half covid as well.
2022-01-20T13:07:00 < BrainDamage> you may say the situation got ... out of hand
2022-01-20T13:08:19 < karlp> qyx: hrm, stop0 is 124uA best case, lpsleep at 400khz is 45uA.  stop1 is actually a powerwin, at ~10uA, but that has a pretty rough wakeup time.  and has that "supply current during wakeup" being pretty non zero if I'm cycling pretty fast.
2022-01-20T13:08:24 < karlp> hrmm.
2022-01-20T13:30:26 < qyx> the lowest I have achieved using lprun on L053 was about 120 uA
2022-01-20T13:30:43 < qyx> hm but it was including the LCD controller
2022-01-20T13:35:06 < qyx> but freertos in tickless mode using rtc as a reference clock, on L4, draws about 100 uA
2022-01-20T13:35:33 < karlp> you mean ST's tickless mode 2 using rtc wakeup?
2022-01-20T13:35:37 < qyx> 16 MHz MSI + stop1 in idle thread
2022-01-20T13:35:48 < karlp> or were you doing that yourself?
2022-01-20T13:35:54 < qyx> no, vanilla freertos with my patch
2022-01-20T13:36:28 < qyx> I didn't even know ST has anything
2022-01-20T13:36:45 < karlp> well, 100 vs 150 is fine, it was this "+200" to have the pll for adc that was bugging me.
2022-01-20T13:37:24 < qyx> what about using G4? doesn't it have finer clock control?
2022-01-20T13:37:51 < karlp> if you choose freertos integration in cube for the wb at least, you get a fairly convoluted setup with tickless mode 2 (custom) that uses ST's  "time server" where they manually manage a linked list of wakeup times using the rtc clock themselves.
2022-01-20T13:38:11 < qyx> what the fuck for
2022-01-20T13:38:22 < karlp> because they can then use the same thing for their examples _without_ freertos :)
2022-01-20T13:38:32 < karlp> but yeah, way more complicated than it need to be
2022-01-20T13:39:06 < qyx> you just need the earliest one + catch thwo or three races
2022-01-20T13:39:33 < karlp> yeah, which freertos does for you...
2022-01-20T13:39:43 < karlp> but thye let user apps _also_ put timers into that linked list.
2022-01-20T13:39:44 < karlp> it's a mess.
2022-01-20T13:40:01 < karlp> just like it looks like i'll still have lots of mess going forward driving the power down.
2022-01-20T13:40:09 < karlp> better get functionality first though right? ;)

2022-01-20T14:05:06 < benishor> should be 3.3, yes
2022-01-20T14:05:23 < PaulFertser> benishor: is it a regular ST Link or clone or on-board from nucleo?
2022-01-20T14:05:50 < PaulFertser> Do you have its JTAG pin 1 connected to target Vcc?
2022-01-20T14:05:54 < benishor> PaulFertser: genuine stlink v2 bought from mouser
2022-01-20T14:06:16 < PaulFertser> benishor: cool, so how do you connect it to the target? Can you confirm with a voltmeter that its Vcc pin is getting 3.3 V?
2022-01-20T14:06:16 < benishor> yes, assuming I didn't bust the pin order
2022-01-20T14:06:45 < benishor> PaulFertser: 3.2V but should be ok

2022-01-20T14:40:46 < benishor> I just upgraded its firmware
2022-01-20T14:41:33 < benishor> it doesn't sound like dead to me
2022-01-20T14:43:01 < ventYl> benishor: in my case, i manually measured voltages which stlink was reported. it reported some ridiculously low voltage such as 0.9V, but in reality, there was 3.3V as it should be

2022-01-20T14:45:58 < benishor> yes
2022-01-20T14:45:59 < benishor> but I can use external power, no worries
2022-01-20T14:46:05 < Mangy_Dog> if youre powering a bluepill from the stlink. make sure youre putting the right voltages to the right pins....
2022-01-20T14:46:12 < Mangy_Dog> stlinks have both 5 and 3.v out
2022-01-20T14:46:14 < Mangy_Dog> 3.3v

2022-01-20T14:46:22 < karlp> vtarget is a sense pin, not a provides pin.
2022-01-20T14:46:26 < benishor> what's the pin 1 here?
2022-01-20T14:46:40 < Mangy_Dog> bluepills have an LDO on the V+ pin and 3.3v on the Vbat pin
2022-01-20T14:46:41 < benishor> top left? or the circle one?
2022-01-20T14:47:23 < Mangy_Dog> the one by the circle
2022-01-20T14:47:28 < Mangy_Dog> the depression
2022-01-20T14:47:31 < Mangy_Dog> thats the pin 1 marker
2022-01-20T14:47:45 < Mangy_Dog> if i remember correctly pin 1 is the one under that
2022-01-20T14:48:53 < benishor> ok, I have a brand new STM32F103C8 chip and a LFQP48 to DIP adapter
2022-01-20T14:49:08 < benishor> I want to connect that directly to stlink and see if I can detect it
2022-01-20T14:51:29 < benishor> no cigar
2022-01-20T15:00:36 < benishor> ok, finally got it
2022-01-20T15:02:01 < benishor> karlp was right. I was using the wrong power pin
2022-01-20T15:02:40 < karlp> I try and view the debugger as something you _add_ to a system, 
2022-01-20T15:03:00 < karlp> and remember that vtarget is for sensing, so that buffers can adjust voltages, not powering things.
2022-01-20T15:05:17 < Mangy_Dog> have you put a chrystal on your board?
2022-01-20T15:05:52 < Mangy_Dog> when i test a chip with a socket thingy, i put a couple of caps on the 3V lines and a crystal osolator 8mhz
2022-01-20T15:05:57 < Mangy_Dog> thats how you get the chip talking

2022-01-20T16:17:11 < Mangy_Dog> Need a little advise on a thought I just had, for SD card based firmware updating of an MCU... Is a boot loader simply a small program thats at flash 0... So basically a normal program id write. But its just the first bit to get exicuted? And sooo... If i made a update system id first right a boot loader bit of program that detects an update file. Then copys the binary to a set location of 
2022-01-20T16:17:11 < Mangy_Dog> the flash, and then trigger the program to start running from that location onward?
2022-01-20T16:17:20 < jpa-> karlp: some chinese stlink clones provide strong +3.3V drive on the pin that is Vsense on normal stlink; that bit me when i had a regulator that doesn't like backfeeding
2022-01-20T16:17:47 < jpa-> Mangy_Dog: correct
2022-01-20T16:18:13 < jpa-> Mangy_Dog: you'll need to set SCB->VTOR to point to the vector table of the main program, set stack pointer and jump into it
2022-01-20T16:18:29 < jpa-> something like  https://github.com/PetteriAimonen/ebike-controller/blob/master/src/bootloader.c#L212
2022-01-20T16:22:45 < karlp> jpa well, peoplebuying undocumented crazy shit get burnt :) (benishor's picture that I made my statement on was with the cased original stlink though, as my defence)
2022-01-20T16:23:22 < karlp> well, cube example says it's "standby mode" and sitll uses 400uA.  can't find anything on the nucleo scheamtic that would be draining extra power.  nice.
2022-01-20T16:23:49 < karlp> ooh, needed to power cycle
2022-01-20T16:23:51 < karlp> nice..
2022-01-20T16:24:00 < karlp> fuck I hate this shit where just unplugging isn' tenough
2022-01-20T16:24:10 < karlp> if only I had a hub that could power the ports on and off....
2022-01-20T16:25:00 < karlp> standby goes down to ~0.76uA now, which is more like the datasheet.
2022-01-20T16:25:07 < karlp> ok, time to conver that...
2022-01-20T16:30:27 < Mangy_Dog> ahh ok jpa
2022-01-20T16:30:49 < Mangy_Dog> skim reading the code... kinda makes sence

2022-01-20T16:31:55 < Mangy_Dog> no idea what that lot means :D
2022-01-20T16:31:55 < mawk> bx is a jump
2022-01-20T16:31:59 < mawk> msr msp is changing the stack
2022-01-20T16:32:04 < Mangy_Dog> oh
2022-01-20T16:32:07 < mawk> this changes the stack and jumps to the main function
2022-01-20T16:32:14 < mawk> changes or sets a stack at all
2022-01-20T16:32:23 < Mangy_Dog> ahh
2022-01-20T16:33:56 < Mangy_Dog> though not entirely sure where the location of __mainprogram_start_ is set
2022-01-20T16:34:19 < mawk> in the .lds file maybe
2022-01-20T16:34:22 < mawk> grep through the code
2022-01-20T16:34:27 < mawk> .lds is linker file
2022-01-20T16:34:40 < mawk> or in assembly in .s

2022-01-20T17:20:51 < PaulFertser> What if your target is 1.8 V?
2022-01-20T17:20:54 < qyx> works
2022-01-20T17:21:11 < qyx> don't ask why, I didn't investigate
2022-01-20T17:21:11 < mawk> yeah I made the stlink shutup about low voltage by connecting to 3.3V, and it was working with a 1.8V target
2022-01-20T17:21:15 < mawk> maybe that wasn't recommended

2022-01-20T17:26:45 < PaulFertser> mawk: but that means your stlink pumps 3.3 V on SWCLK I think. Probly that's ok for a 5 V tolerant pin.
2022-01-20T17:26:59 < mawk> yeah PaulFertser 
2022-01-20T17:27:22 < PaulFertser> mawk: but it's not about shutting up or not. With vcc floating it wouldn't be giving out any meaningful signal at all.

2022-01-20T18:02:45 < zyp> aww
2022-01-20T18:04:02 < mawk> what did you do Steffann 
2022-01-20T18:05:00 < Steffann> Test some boards.
2022-01-20T18:13:11 < mawk> I have a pile of around 100 boards to test too
2022-01-20T18:13:22 < mawk> but I found the perfect way to deal with it without being bored: not do it
2022-01-20T18:15:19 < kakium69> make testing part of your design process
2022-01-20T18:15:27 < kakium69> implement self-test
2022-01-20T18:16:21 < BrainDamage> the boring part is still attaching all connectors, and for signal integrity's sake, not everything can fit on a pin header strip
2022-01-20T18:19:53 < ventYl> did you notice?
2022-01-20T18:20:43 < mawk> to test them I have only a broken tag connect
2022-01-20T18:20:48 < mawk> which I need to hold by hand or with tape

2022-01-20T18:21:06 < BrainDamage> which I imagine it's going to be pretty tiring

2022-01-20T18:30:19 < ventYl> I designed one for mine :) it wasn't even broken

2022-01-20T21:55:08 < fenugrec> speaking of units (the other day), I learned that a lot of US surveyors use the "US survey foot" (vs the "international foot" !!!), and there is "a lot of resistance" to "standardize" to the int'l foot

2022-01-20T21:59:09 < fenugrec> for one thing I guess, tons and tons of legacy surveys based on the foot

2022-01-20T23:48:27 < catphish> though interestingly, this one looks *way* better then the ones on wikipedia, it's been restored in a big way
2022-01-20T23:48:52 < kakium69> it's at least 50k
2022-01-20T23:48:59 < kakium69> gbp
2022-01-20T23:49:14 < catphish> it certainly is now!

2022-01-20T23:51:46 < catphish> lol
2022-01-20T23:52:15 < catphish> hopefully it'll be more valuable when it's a running EV :)
2022-01-20T23:52:41 < kakium69> maybe

2022-01-20T23:59:16 < catphish> i'm guessing maybe anything from 50 to 100 miles depending on driving style

2022-01-20T23:59:31 < catphish> yeah 100 of your european kilometers

2022-01-21T00:23:19 < catphish> 1) it uses a new file format, i didn't want to break compatibility with anyone else who might want to access my projects but hadn't upgraded yet 2) the curved traces, while cool, were not trivial to use 3) the raytraced view had some trouble with some of my STEP models 4) the UI is just different, and i don't fancy changing habits until it's mainstream

2022-01-21T00:24:29 < qyx> idk whats the actual state of Eagle
2022-01-21T00:24:37 < qyx> I stopped using it at v7
2022-01-21T00:24:59 < catphish> i pretty much love kicad v5, the only thing i want is curvier traces :)
2022-01-21T00:25:00 < qyx> catphish: I concluded the same
2022-01-21T00:25:20 < steve__> i think I had EAGLE 9 and it's like the same as whatever I used in 2014
2022-01-21T00:25:39 < qyx> if you want a trace or two curved, you can workaround it
2022-01-21T00:25:50 < qyx> I did use it for antenna connections
2022-01-21T00:26:15 < qyx> but not worth it, it will bite you later
2022-01-21T00:26:30 < steve__> there's just a bunch of stuff you can't do in kicad.  eagle has ULP to compensate, dunno if kicad has?
2022-01-21T00:27:01 < catphish> also, if kicad could include hookers in the licence cost, that would probably help
2022-01-21T00:27:27 < steve__> wat?  it's free
2022-01-21T00:27:43 < qyx> steve__: python
2022-01-21T00:27:54 < qyx> and python >>>>>>> ULP
2022-01-21T00:28:14 < steve__> ahhh, great

2022-01-21T00:28:43 < steve__> so you can program your own hookers in
2022-01-21T00:30:06 < qyx> but there were some compatibility issues
2022-01-21T00:30:10 < qyx> v2/v3

2022-01-21T00:39:20 < PaulFertser> mawk: that's probably true, doesn't sound too unlikely.
2022-01-21T00:39:52 < PaulFertser> Unfortunately, won't help russia that much, so many people here do not want to get vaccinated and do not want to wear masks properly.
2022-01-21T00:41:18 < BrainDamage> why no masks? I find that one of the few nice things is that they help you against cold air
2022-01-21T00:41:43 < BrainDamage> or do people there wear full face balaclavas in the winter?
2022-01-21T00:43:01 < PaulFertser> Not many, common people prefer scarfs.
2022-01-21T00:44:24 < PaulFertser> Balaclavas are used by construction (and others who have to spend much time outside professionally) workers, winter push bikers etc.
2022-01-21T00:45:13 < PaulFertser> Yes, I often wear mask to protect me from cold wind. But the problem is that people inside a bus or a metro train often put them down.
2022-01-21T00:46:00 < ventYl> qyx: current state of eagle is, that autodesk bought it and they pretty much baked parts of it into fusion 360

2022-01-21T11:48:33 < karlp> catphish: I've beenusing kicad6 for over a year, can't imagine using 5.x
2022-01-21T11:48:44 < karlp> not having to fucking gnerate netlists and reimport them is massive.
2022-01-21T11:48:58 < karlp> named nets in pcbview, though I think they ended up backporting that to 5.1
2022-01-21T11:49:10 < karlp> the push and shove router
2022-01-21T11:49:12 < jpa-> eh, update from schematic button has been in 5.1 for at least two years now also
2022-01-21T11:49:33 < jpa-> and named nets and push and shove and so on
2022-01-21T11:49:43 < karlp> they backported all of it to 5.1?
2022-01-21T11:49:58 < karlp> no wonder they take so long to fucking deliver shit if they're wasting resources like that.
2022-01-21T11:50:09 < jpa-> seems so, nothing of that sounds new to me after using 5.1
2022-01-21T11:50:10 < karlp> it absolutely wasn't available when I tried 5.x first.
2022-01-21T11:50:43 < karlp> unbelievable waste of resources
2022-01-21T11:50:44 < jpa-> i switched to kicad 6 in december, hit a bunch of bugs that were fixed some time later
2022-01-21T11:50:59 < jpa-> currently it feels ok, but slower than kicad 5
2022-01-21T11:51:10 < jpa-> especially DRC is now very slow and interactive router is slower also
2022-01-21T11:51:20  * karlp sighs
2022-01-21T11:51:29 < karlp> kicad 5.x was simply lacking features when I started.
2022-01-21T11:51:42 < karlp> now you're telling me they made 5.x better and 6 is worese?!
2022-01-21T11:51:47 < karlp> this is fucking crazy.
2022-01-21T11:51:56 < karlp> what a fucking week
2022-01-21T11:52:09 < jpa-> are you sure you aren't thinking of kicad 4? because IIRC push&shove router was in kicad 5 right from the start
2022-01-21T11:52:40 < jpa-> nicest thing in kicad 6: embedding symbols in schematic so that stuff doesn't break every time you upgrade kicad
2022-01-21T11:52:46 < jpa-> and that feels almost a must-have
2022-01-21T11:52:49 < karlp> oh yeah, that one is big too.
2022-01-21T11:52:57 < karlp> I'd forgotten that one.
2022-01-21T11:53:10 < jpa-> i can confirm that it is a feature that is missing from 5.1 :)
2022-01-21T11:53:45 < karlp> hrm, there was some reason in particular I started using the nightly, 
2022-01-21T11:53:53 < jpa-> also it seems that some things work differently in kicad 6, in kicad 5 i could press delete to remove another net while the route tool is active
2022-01-21T11:53:53 < karlp> whatever, I'm on 6.x now.
2022-01-21T11:54:23 < jpa-> yeah, i'm also moving to kicad 6 when possible, though i expect some clients will keep me using 5.1 in parallel for quite a while
2022-01-21T11:55:07 < catphish> <karlp> not having to fucking gnerate netlists and reimport them is massive. << why? i've never done this
2022-01-21T11:56:05 < catphish> oh, answered above, it's fixed in 5.1
2022-01-21T11:56:36 < catphish> i've been using kicad for *years* though, and never had to manually import a netlist afaik
2022-01-21T11:57:41 < jpa-> i did, in kicad 4 and keeped doing that in kicad 5 for a while also because i didn't notice the button :)
2022-01-21T12:00:04 < karlp> 5.0 has the "
2022-01-21T12:00:06 < karlp> Update changes from schematic editor without intermediate netlist file
2022-01-21T12:00:17 < karlp> " line in it, so at some stage I must have been on a late 4.x
2022-01-21T12:01:42 < jpa-> log has:  2019-08-21T02:48:20 < karlp> man, new interactive puhs/shove routing thing in kicad 6 nightlies is awesome
2022-01-21T12:02:07 < jpa-> at that point i think it was in 5.1 already also
2022-01-21T12:02:17 < jpa-> though in the initial versions it didn't work very well
2022-01-21T12:05:13 < karlp> I must have had a 5.x version that _didn't_ have it to hve tried out a 5.99 that did?
2022-01-21T12:05:29 < karlp> it only worked in some weird renderingmode initially maybe?
2022-01-21T12:05:31  * karlp shrugs
2022-01-21T12:05:35 < karlp> too late now.
2022-01-21T12:05:50 < karlp> back to trying to make basic elementary functions work and try not to cry.
2022-01-21T12:06:11 < karlp> but a dim sum lunch date to look forward to, not all bad today :)
2022-01-21T12:07:17 < karlp> what I _don't_ recommend right now is the 6.99 nightlies :)
2022-01-21T12:07:33 < karlp> they've _already_ changed the project files again, 
2022-01-21T12:07:40 < karlp> forward compat only,

2022-01-21T12:14:48 < karlp> so internet: 1, supporting local entrepreneurs: 0
2022-01-21T12:17:28 < PaulFertser> karlp: resin doesn't compete with FDM...
2022-01-21T12:17:36 < PaulFertser> karlp: also, still no photos?
2022-01-21T12:18:13 < karlp> well locals shouldn't offer fdm then...
2022-01-21T12:18:48 < PaulFertser> It depends on the specifics of use case a lot.
2022-01-21T12:18:54 < karlp> this has however strengthened my opinion that I would only buy a resin printer for myself.
2022-01-21T12:19:19 < PaulFertser> It's hard to tell what is suitable and what isn't without knowing how exactly the print is to be used.

2022-01-21T12:21:07 < PaulFertser> Depends on what you plan to use it for. My latest usecase is a tool to help removing and installing valve cotters. I'm not sure SLS would make it, I think it'd be too brittle.

2022-01-21T12:21:28 < karlp> wel, SLS is different again.
2022-01-21T12:21:43 < PaulFertser> SLA I meant
2022-01-21T12:22:19 < PaulFertser> SLS would be fine :)
2022-01-21T12:22:40 < karlp> sure, but craftcloud I can pick anyway, including metal.  the local guys are offering me petg, pla or abs, on FDM only. 
2022-01-21T12:23:03 < karlp> and they're not cheap enough or reliable enough to use them again.
2022-01-21T12:42:14 < zyp> the way I see it, SLA and FDM have different uses
2022-01-21T12:43:34 < zyp> but yeah, the level of support you got from your locals is around what I expect to get if I ask one of my friends to print me something for free :p
2022-01-21T12:45:49 < zyp> if I paid somebody to print something, I'd absolutely expect them to take care of the necessary iterating to get the required precision
2022-01-21T12:54:03 < qyx> karlp: I am on 5.1.10 and have all the mentioned features
2022-01-21T12:54:22 < qyx> so apparently not much reason to move to 6.x
2022-01-21T12:57:34 < jpa-> qyx: except the bundled symbols with schematic
2022-01-21T12:59:25 < karlp> ah, I know a feature you need!  setting different colour solder masks for front and back sides of your board in the board stackup editor :)
2022-01-21T12:59:31 < karlp> and having that work in 3d view :)
2022-01-21T13:00:13 < karlp> register dump comparisons between vendor code and "cool" code is pretty boring. especially when they all seem to agree :|
2022-01-21T13:29:21 < karlp> whee.

2022-01-21T13:29:41 < karlp> because the only place that had the magic number for what exti is connectd to the rtc is the _nvic_ tables.
2022-01-21T13:30:00 < karlp> rtc section and exti section talk about syscfg unmasking and blah, but noooo.
2022-01-21T13:31:53 < qyx> are you trying to make money or clean code?
2022-01-21T13:32:12 < qyx> those are two non-overlapping activities
2022-01-21T13:32:56 < karlp> this is a valid question, which I refuse to answer.
2022-01-21T13:35:53 < qyx> tell me when you decide
2022-01-21T13:35:59 < qyx> I need an answer too
2022-01-21T13:38:00 < karlp> ok, well I have rtc wakeup inrqs, but I cna't clear the flag properly so it fires continuously.
2022-01-21T13:38:22 < karlp> and of course, _normally_ you are in deep sleep, with no handler attached, just the "wakeup" event. 
2022-01-21T13:38:26 < karlp> so yolo right?
2022-01-21T13:46:23 < ventYl> new boiler reported 5.4kW output at -10 C this morning. old boiler wasn't able of throttling itself down below 6kW at all
2022-01-21T13:47:35 < BrainDamage> so it had only option of steam vs super saturated steam?
2022-01-21T13:49:07 < karlp> ok, gotta clear exti _before_ clear flag in rtc.  nice of that to be obvious in the manuals...
2022-01-21T14:10:59 < ventYl> BrainDamage: it turned itself off every now and then in order to prevent overheating the building
2022-01-21T14:11:34 < BrainDamage> melting*
2022-01-21T14:11:49 < ventYl> 6kW is not that much for a building
2022-01-21T14:13:37 < BrainDamage> 6kW min
2022-01-21T14:13:45 < BrainDamage> you didn't state an upper bound
2022-01-21T14:13:51 < BrainDamage> it could be 6GW
2022-01-21T14:15:10 < ventYl> upper bound was 24kW, mostly ever used only during DWH cycle
2022-01-21T14:15:56 < ventYl> I don't have licence to operate nuclear reactors :)
2022-01-21T14:18:22 < qyx> you know the quote "If you owe the bank $100 that's your problem. If you owe the bank $100 million, that's the bank's problem"
2022-01-21T14:19:03 < qyx> if you managed to start a nuclear reactor in your garden, it would not be your problem anymore
2022-01-21T14:19:47 < BrainDamage> my univ literally had a nuclear reactor in the garden
2022-01-21T14:20:36 < qyx> new building of my uni was built on a planned reactor base
2022-01-21T14:20:40 < qyx> at least it is said so
2022-01-21T14:21:07 < qyx> it was meant to be some scientific experiment, abandoned later
2022-01-21T14:21:17 < ventYl> many universities have nuclear reactors in the basements
2022-01-21T14:22:53 < BrainDamage> yeah, but once they dismissed it and the radiation levels got down to safe levels they literally parked the core in one of the gardens
2022-01-21T14:23:02 < BrainDamage> as a fancy sculpture
2022-01-21T14:23:34 < ventYl> is there a photo of it?
2022-01-21T14:24:24 < BrainDamage> this is when it was assembled
2022-01-21T14:24:25 < BrainDamage> https://www.museovirtuale.polimi.it/wp-content/uploads/2019/12/eng2.jpg
2022-01-21T14:24:33 < BrainDamage> lemme search for one in the garden
2022-01-21T14:26:40 < qyx> whats the current state of art wrt small scale garden reactors?
2022-01-21T14:26:46 < qyx> BrainDamage may actually know
2022-01-21T14:28:53 < BrainDamage> the military tried a bit in the 60 to 70s with discrete success, the problem is the continous maintenance
2022-01-21T14:29:01 < BrainDamage> they got replaced by RTG
2022-01-21T14:29:12 < BrainDamage> which require pretty much 0 maintenance
2022-01-21T14:29:38 < BrainDamage> there's a famous accident of someone impaled to the ceiling wrt small scale reactors
2022-01-21T14:30:04 < ventYl> russians were using small reactors on remote lighthouses, so the maintenance isn't that much of a concern
2022-01-21T14:30:07 < ventYl> at least for them
2022-01-21T14:30:17 < ventYl> one peninsula more, or less, who even cares
2022-01-21T14:30:43 < qyx> yeah in russia there are many abandoned RTGs
2022-01-21T14:31:46 < karlp> those were RTGs though, not "reactors"
2022-01-21T14:32:18 < qyx> RTG is fine for a household heat&power unit :>
2022-01-21T14:32:36 < karlp> sure, but thye're not _that_ much power
2022-01-21T14:32:44 < karlp> like, their _only_ advantage is the zero maintennance
2022-01-21T14:33:24 < BrainDamage> yeah, reactors have much higher energy density, but require constant vigilance and active maintenance
2022-01-21T14:33:39 < karlp> ok. extiworking, now back up to rtc working, what's the next step up the chain to what I was trying to do at the start of the week?
2022-01-21T14:33:43 < BrainDamage> rtg 0 maintenance, but poor energy density ( compared to reactors )

2022-01-21T17:39:14 < kakium69> ah yes
2022-01-21T17:39:31 < zyp> or I guess constinit is most conventient for what you want to do

2022-01-21T17:40:41 < kakium69> maybe
2022-01-21T17:44:47 < kakium69> if I can write it like C from 90's

2022-01-21T17:45:40 < kakium69> maybe I use C++
2022-01-21T17:45:42 < zyp> fuck template magic, just do constexpr/constinit

2022-01-21T20:11:33 < steve__> i see a lot of cpp people who don't know what a translation unit is, and tend to use very few .cpp files and a lot of complicated templated headers, in an attempt to optimize  but almost guaranteed to make things worse and take hours to compile a tiny application

2022-01-21T20:40:18 < mawk> but not all constexpr stuff is supported in earlier versions

2022-01-21T20:48:00 < jpa-> well yeah, including binary data in a program isn't a very effective use of constexpr IMO

2022-01-21T21:18:43 < steve__> the static typing of constexpr is useful, it's more convenient to write tests against it when you have it in software.  I'd consider a compromise, binary data is constexpr but stored in a separate compilation unit

2022-01-21T21:26:01 < steve__> runtime is the same as compiletime if your runtime is at compiletime.  so it doesn't really matter if you use constexpr, vs. execute a program to generate data.
2022-01-21T21:36:35 < jpa-> except that constexpr evaluation is usually a lot slower than a compiled program
2022-01-21T21:43:58 < zyp> jpa-, the point wasn't to include binary data, the point was to precalculate a lookup table
2022-01-21T21:44:46 < steve__> yeah that's why i mentioned the above, that you only compute it once and stick in a .o, instead of in a .h where it has to be computed for every .cpp that includes it.  not 100% sure but I believe this can be done with no overhead
2022-01-21T21:45:11 < zyp> that's besides the point
2022-01-21T21:45:21 < steve__> zyp yea I was doing that for filter coefficients, worked well
2022-01-21T21:46:20 < zyp> it makes absolutely no sense to include the same lookup table in multiple translation units
2022-01-21T21:47:28 < zyp> I mean, best case the linker can fold them into a common symbol still, worst case you get a bunch of redundant copies eating flash
2022-01-21T21:47:49 < steve__> i agree, that's what i was getting at
2022-01-21T21:53:13 < zyp> I don't really follow your argument; to me templates, constexpr and translation units are pretty orthogonal concepts
2022-01-21T21:56:52 < steve__> not talking about templates.  im basically saying what you just said, a constexpr should be in exactly 1 object file, except maybe in the case where you it absolutely has to be inlined and there's no way to make it happen.
2022-01-21T21:57:40 < zyp> a constexpr what?
2022-01-21T21:58:10 < jpa-> zyp: depends whose point, apparently mawk's point was including binary data, even though that was completely unrelated to the original question

2022-01-21T22:05:58 < zyp> personally I like sticking everything into one translation unit, but that's just because it's annoying to deal with the header/source split

2022-01-21T22:34:31 < karlp> sure, like I said, it's super legible to _read_
2022-01-21T22:34:41 < karlp> I just can't imagine getting to the point where I could bang it out myself :)
2022-01-21T22:34:48 < karlp> but maybe more practice...
2022-01-21T22:38:35 < zyp> shouldn't really be anything exotic there apart from std::array

2022-01-21T22:56:58 < zyp> PaulFertser, what do you mean? I'm not using concepts
2022-01-21T23:00:04 < PaulFertser> zyp: I think template <int N> is some new syntax
2022-01-21T23:00:44 < mawk> it's already in C++11 I think
2022-01-21T23:00:56 < zyp> it's way older than that
2022-01-21T23:01:13 < zyp> non-type template arguments have existed as long as templates itself
2022-01-21T23:02:21 < ventYl> C++89
2022-01-21T23:02:36 < ventYl> which is exactly as long as Microsoft is not able to implement templates to the standard
2022-01-21T23:02:41 < PaulFertser> I can't understand https://en.cppreference.com/w/cpp/language/template_parameters#Type_template_parameter then
2022-01-21T23:04:07 < catphish> my gear knob arrived today, exciting! https://www.aliexpress.com/item/4000801575813.html
2022-01-21T23:05:46 < ventYl> PaulFertser: template <int N> is not concept syntax
2022-01-21T23:06:04 < ventYl> that's old stuff, yet I haven't studied concept syntax deep enough yet
2022-01-21T23:06:31 < PaulFertser> ventYl: please tell me which type of a template parameter that is.
2022-01-21T23:07:52 < zyp> PaulFertser, it's a non-type template parameter, accepting an integer
2022-01-21T23:08:17 < zyp> the integer is the number of entries in the generated lookup table
2022-01-21T23:08:28 < PaulFertser> zyp: thank you, got it
2022-01-21T23:09:00 < PaulFertser> Should have been reading https://en.cppreference.com/w/cpp/language/template_parameters#Non-type_template_parameter indeed
2022-01-21T23:09:20 < ventYl> PaulFertser: non-type integral parameter
2022-01-21T23:09:32 < ventYl> yeah
2022-01-21T23:09:51 < ventYl> it is used e.g. in std::tuple::get<int n>()
2022-01-21T23:10:07 < PaulFertser> Silly me
2022-01-21T23:10:09 < zyp> and also gen_table<20>();
2022-01-21T23:10:16 < ventYl> which one could argue, is fugly syntax
2022-01-21T23:10:48 < ventYl> PaulFertser: also, it is not that often used. unless you need to parametrize your code or you love Haskell
2022-01-21T23:11:00 < ventYl> or are a Boost developer
2022-01-21T23:11:24 < PaulFertser> ventYl: I like Haskell actually
2022-01-21T23:11:45 < zyp> uh, it's pretty common if you have a type with configurable size
2022-01-21T23:11:52 < zyp> like std::array
2022-01-21T23:12:17 < zyp> and std::ratio which std::chrono builds on is also pretty damn useful
2022-01-21T23:12:26 < ventYl> well, yeah. but I ever only wrote maybe one template using int argument
2022-01-21T23:13:34 < ventYl> variardic templates... hell yeah
2022-01-21T23:19:45 < karlp> zyp: I think I'm just not enough of a cpp person at all to actually understand the syntax beyond C :)
2022-01-21T23:20:16 < karlp> like the template having int N or int, N I would never figure out
2022-01-21T23:20:53 < zyp> sounds like a karlp problem, not a C++ problem :)
2022-01-21T23:21:28 < karlp> I don't undestand why these functions have to have const at the end of the decl either, so it's just my problems really I guess :) https://paste.jvnv.net/view/7CC1g
2022-01-21T23:22:04 < zyp> because the RTC instance is const
2022-01-21T23:22:26 < karlp> like you said, "karlp problems" :)
2022-01-21T23:22:29 < zyp> if you got a const instance/reference/pointer, you can only call const methods
2022-01-21T23:22:47 < karlp> is that just saying I can't override it?
2022-01-21T23:23:03 < ventYl> basically yes
2022-01-21T23:23:05 < zyp> by declaring the method const like that, you're allowing it to be called on a const object
2022-01-21T23:23:10 < ventYl> not override, just modify
2022-01-21T23:23:18 < karlp> I mean, to me, it's not a "const" method, the method must be called every time...
2022-01-21T23:23:31 < zyp> it's effectively saying «this method doesn't modify the object»
2022-01-21T23:23:50 < karlp> that's a  nice way of putting it.
2022-01-21T23:23:53 < ventYl> karlp: const methods can't modify this, non-const method can. if you have count *, you can't call non-const method on it
2022-01-21T23:24:09 < ventYl> s/count */const */
2022-01-21T23:25:38 < zyp> karlp, the only data member of the class is the underlying address that ptr() casts to a pointer, so that is what you aren't allowed to modify

2022-01-21T23:27:02 < zyp> yeah, no:)
2022-01-21T23:27:17 < zyp> but getting it to compile should be most of the way there

2022-01-21T23:32:15 < zyp> nice :)
2022-01-21T23:32:43 < zyp> have you published it yet?
2022-01-21T23:32:44 < karlp> going to go back over it from the beginning, getting sidetracked for a few days on basics put me off the rhythm a little bit.
2022-01-21T23:32:51 < karlp> it's all in karl-top2 on github.
2022-01-21T23:33:13 < karlp> I've been (and will continue) to rebase and push -f, but I'm keeping all the "early" commits as final as I can.
2022-01-21T23:34:57 < zyp> I didn't find any unpublished commits from my side on work computer, but I think I should recheck that
2022-01-21T23:35:30 < karlp> https://github.com/karlp/laks/commits/karl-top2 is it.
2022-01-21T23:36:02 < karlp> most of it's fairly straightforward, but you might have c++ style improvements or taste preferences on the debug itm stuff,
2022-01-21T23:36:14 < karlp> I just went with jpa's https://github.com/karlp/laks/commit/260fae7a81abc5b6e97a5c9a32db13d57b7187ca last night instead of adding to yaml as well, 
2022-01-21T23:38:40 < zyp> I don't like that magic «- 2»
2022-01-21T23:38:55 < zyp> that's the sort of hack that'll bite you later :)
2022-01-21T23:39:15 < karlp> well, it's f1, it won't :)
2022-01-21T23:39:22 < karlp> not me at least ;)
2022-01-21T23:39:48 < jpa-> muahaha, i'm corrupting you all!
2022-01-21T23:39:55 < karlp> hrm, only 7 threads, I think one's missing...
2022-01-21T23:41:04 < zyp> you're still assuming GPIOv2 will always have GPIOA mapped on a 16k alignment
2022-01-21T23:41:05 < zyp> :)
2022-01-21T23:41:22 < karlp> if it doesn't, it stops being gpiov2 will be my defense :)
2022-01-21T23:41:38 < karlp> but yeah, I do agree, putting it in the yaml is _probably_ the right choice.
2022-01-21T23:41:48 < qyx> yaml :S
2022-01-21T23:41:54 < karlp> well, I can't change his mind on that one :)
2022-01-21T23:42:33 < zyp> yaml > json > xml or so
2022-01-21T23:42:33 < qyx> when is zbml coming?
2022-01-21T23:42:43 < qyx> zbml > yaml > json > whatever
2022-01-21T23:44:07 < qyx> yaml is retarded in more ways, mandating spaces to begin with
2022-01-21T23:44:48 < zyp> if you're gonna indent it for readability anyway, what does it matter of they are mandatory?
2022-01-21T23:45:18 < qyx> it should be readable when indented the proper way using tabs
2022-01-21T23:45:25 < qyx> you are not supposed to do space-paintings
2022-01-21T23:46:00 < zyp> but I mean, shit is just data, could always just convert it if some better format comes along
2022-01-21T23:46:17 < zyp> hmm
2022-01-21T23:46:28 < zyp> I think I've given up the tab vs spaces war
2022-01-21T23:46:45 < qyx> me too, tab is the winner
2022-01-21T23:46:45 < BrainDamage> yeah, the worst part of yaml is that I never get indentation right when it's arrays vs dicts
2022-01-21T23:46:56 < zyp> I used to be on the tab side, but lately I find myself using spaces
2022-01-21T23:47:22 < qyx> I am stopping programming in python the day they staart mandating spaces
2022-01-21T23:48:00 < ventYl> well, that's one of the most annoying features of python
2022-01-21T23:48:23 < zyp> that indentation matters?
2022-01-21T23:48:26 < BrainDamage> they are heavily recomended, but not enforced fortunately
2022-01-21T23:48:57 < qyx> no, that it is too nice to people not indenting properly
2022-01-21T23:49:23 < ventYl> zyp: the way it enforces one and only right indentation
2022-01-21T23:49:35 < qyx> "oh but but my codez will look bad when you set your editor to tab=8 spaces!"
2022-01-21T23:49:52 < mawk> go for 16
2022-01-21T23:49:53 < qyx> ventYl: oh thats the best one
2022-01-21T23:50:34 < BrainDamage> there's this weird fetish about controlling the style of text at absolute cost
2022-01-21T23:50:44 < BrainDamage> it's becoming pervasive on the web
2022-01-21T23:50:59 < BrainDamage> who cares if it doesn't look pixel perfect on every device, not all devices are equal either
2022-01-21T23:51:04 < zyp> it's fucking bikeshedding
2022-01-21T23:51:17 < ventYl> or may be fucking retarded automotive moron who decided, that two spaces FTW!
2022-01-21T23:51:23 < qyx> fortunately I don't know what bikeshedding is
2022-01-21T23:51:23 < ventYl> or even better, *one* fucking space
2022-01-21T23:51:28 < qyx> but let's bikeshed ADC on G4
2022-01-21T23:51:29 < ventYl> is all you'll ever need

2022-01-21T23:53:36 < catphish> lol such bikeshed, very time waste
2022-01-21T23:53:38 < qyx> on a more ontopic note, whats the current and obtainable stm32 with ethernet besides esp32 and gd32?
2022-01-21T23:54:11 < qyx> only F105/7, F405/7, F7 and H7 got ethernet?
2022-01-21T23:54:22 < karlp> chv307 has ethernet, even a 10MB phy built in ;)
2022-01-21T23:54:23 < zyp> I mean, if I got to decide indentation style for everybody, I'd go with tabs, but at this point I wouldn't mind if python started mandating four spaces or whatever, simply because that'd put an end to arguments over which are better
2022-01-21T23:54:38 < karlp> they'll never agree on the number though
2022-01-21T23:54:42 < qyx> karlp: yeah but I need one for 10base.t1l, so rmii prefered
2022-01-21T23:55:04 < karlp> qyx it's got a 10/100/1000 mac, so it can talk rmii too ;)
2022-01-21T23:55:16 < qyx> thats interesting
2022-01-21T23:55:22 < qyx> rgmii I suppose, not sgmii
2022-01-21T23:55:30 < karlp> I've not looked at that part at all
2022-01-21T23:55:35 < qyx> I'll check
2022-01-21T23:55:49 < zyp> chv307?
2022-01-21T23:56:08 < qyx> yeah a new piece of chink riscv awesomeness
2022-01-21T23:56:25 < qyx> new gd32
2022-01-21T23:56:26 < zyp> google is not turning up anything useful
2022-01-21T23:56:28 < karlp> well, iirc, the 307 or whatever is actualyl cortex,
2022-01-21T23:56:36 < karlp> and the riscv ones are the bluetooth
2022-01-21T23:56:45 < zyp> ah, ch32v307

2022-01-21T23:57:10 < zyp> https://github.com/openwch/ch32v307 looks riscv to me
2022-01-21T23:57:24 < catphish> ch32v307 looks fun
2022-01-21T23:57:34 < karlp> they have ch32f parts as well.
2022-01-21T23:58:03 < karlp> and ch5xx bluetooth with cortex and ch5xx bluetooth ones with riscv

2022-01-22T17:13:51 < Laurenceb> or can_dev uses mcp251x? (makes more sensor)
2022-01-22T17:13:53 < Laurenceb> *sense
2022-01-22T17:20:08 < mawk> mcp251x uses can_dev
2022-01-22T17:20:32 < mawk> that number is the refcount of the module
2022-01-22T17:21:06 < Xogium> can I say I hate dracut ? Oops I did
2022-01-22T17:21:36 < Xogium> dracut requires sed and grep and findutils
2022-01-22T17:22:05 < Xogium> but the most fun part is, if you don't have them it silently fails to run properly and makes completely buggy devices in systemd
2022-01-22T17:22:23 < Xogium> and it doesn't tell you that sed and friends were not found

2022-01-22T18:12:47 < Laurenceb> hmm wtf
2022-01-22T18:13:06 < Laurenceb> if I use popen in Lunix, but the subprocess dies immediately, how do I recover?
2022-01-22T18:13:29 < Laurenceb> getting this atm Program received signal SIGPIPE, Broken pipe.
2022-01-22T18:14:39 < Laurenceb> seems like a race condition
2022-01-22T18:15:10 < Laurenceb> my subprocess could die at any time, even just as it opens
2022-01-22T18:17:35 < mawk> it's not a race condition
2022-01-22T18:17:41 < mawk> it's intended behavior
2022-01-22T18:17:53 < mawk> you receive SIGPIPE when you write to a closed pipe
2022-01-22T18:17:55 < mawk> Laurenceb 
2022-01-22T18:18:17 < Laurenceb> hmm ok so I need a signal handler function?
2022-01-22T18:18:25 < mawk> you can also ignore the signal 
2022-01-22T18:18:33 < mawk> and consider the return value of the write() on the pipe
2022-01-22T18:18:40 < mawk> if there's an error just assume it's dead
2022-01-22T18:18:44 < mawk> same for read
2022-01-22T18:19:01 < Laurenceb> hmm ok
2022-01-22T18:19:06 < mawk> the signal is launched on write() anyway
2022-01-22T18:19:11 < Laurenceb> atm I think it causes my program to abort
2022-01-22T18:19:16 < mawk> yeah
2022-01-22T18:19:22 < mawk> it's the default behavior
2022-01-22T18:19:31 < mawk> use setsignal to ignore SIGPIPE
2022-01-22T18:19:35 < Laurenceb> ah ok
2022-01-22T18:19:44 < Laurenceb> so then pclose will give me an error?
2022-01-22T18:19:52 < Laurenceb> which is what I want
2022-01-22T18:19:54 < mawk> probably yes
2022-01-22T18:20:28 < mawk> you can also track precisely when the process dies and why
2022-01-22T18:20:34 < mawk> but not with popen
2022-01-22T18:20:37 < mawk> you need the pid

2022-01-22T18:23:29 < Laurenceb> yeah I dont really mind as I know the source of the issue - its hyperloop WAN modules, their ethernet interface dies for tens of milliseconds whilst they connect to a new base station
2022-01-22T18:23:48 < Laurenceb> so my ethernet stops working properly
2022-01-22T18:26:07 < Laurenceb> quality hardware
2022-01-22T18:26:21 < mawk> lol
2022-01-22T18:27:07 < Laurenceb> I get a "interface temporarily unavailable" error from Lunix
2022-01-22T18:27:19 < mawk> maybe you can ignore it
2022-01-22T18:27:30 < mawk> and start again
2022-01-22T18:27:35 < mawk> no ?
2022-01-22T18:27:56 < mawk> are you doing raw ethernet packets?
2022-01-22T18:28:18 < Laurenceb> yeah I ignore and retry, but it causes my submit task to immediately abort
2022-01-22T18:28:22 < mawk> try the option keep_routes_on_linkdown on the interface
2022-01-22T18:28:25 < Laurenceb> which gives SIGPIPE
2022-01-22T18:28:29 < mawk> yeah

2022-01-22T18:34:23 < mawk> the vpn is over what
2022-01-22T18:34:28 < mawk> tcp?
2022-01-22T18:34:42 < mawk> you played with ssl so I assume yes
2022-01-22T18:34:51 < Laurenceb> yeah
2022-01-22T18:34:53 < mawk> tcp shouldn't die when interface is down
2022-01-22T18:34:58 < mawk> you have a bug somewhere
2022-01-22T18:35:00 < qyx> how so
2022-01-22T18:36:18 < mawk> you have retries
2022-01-22T18:36:36 < mawk> but you have to keep your routes up on down
2022-01-22T18:37:40 < qyx> but you are right, I just checked
2022-01-22T18:48:27 < mawk> if there is no route left I think the tcp session might die at the next retry but I'm not sure
2022-01-22T18:48:36 < mawk> and you can always add a blackhole to prevent that

2022-01-22T18:56:44 < ventYl> dunno why they called it like that
2022-01-22T18:57:48 < mawk> why did you not use openvpn Laurenceb 
2022-01-22T18:57:56 < mawk> it does exactly what you did with openssl

2022-01-22T21:36:03 < Laurenceb> should unloading and reloading a kernel module be equivalent to rebooting lunix?
2022-01-22T21:36:18 < Laurenceb>  -  as far as hardware that connects via that kernel module is concerned?
2022-01-22T21:37:18 < mawk> not really
2022-01-22T21:37:20 < BrainDamage> in theory yes, but that's only if the module devs did their job properly
2022-01-22T21:37:22 < mawk> but it might work
2022-01-22T21:37:28 < BrainDamage> reinitializing everything
2022-01-22T21:37:38 < mawk> if it's a pci device for instance then your driver will use kernel functions to manage it
2022-01-22T21:37:40 < BrainDamage> in practice it may not be
2022-01-22T21:38:23 < BrainDamage> the problem is mostly the internal state of the hw
2022-01-22T21:38:48 < BrainDamage> if the module doesn't reset it, you'll never know what state it's in
2022-01-22T21:39:03 < Laurenceb> its an spi can interface
2022-01-22T21:39:26 < BrainDamage> the best thing to do is: try and see
2022-01-22T21:39:33 < BrainDamage> you might be lucky, might be not
2022-01-22T21:39:35 < Laurenceb> it resets the device over spi, but only when its first initialised or if it detects a limited range of error states

2022-01-22T22:25:20 < qyx> are you doing CAN on your hyperloopz without a native CAN MAC?
2022-01-22T22:25:37 < qyx> do you use raspberry?

2022-01-22T23:04:57 < Laurenceb> aha chrt
2022-01-22T23:08:10 < mawk> yes Laurenceb 
2022-01-22T23:08:20 < mawk> but you need a preempt-rt kernel for it to be effective
2022-01-22T23:08:30 < mawk> otherwise the kernel can still stall you
2022-01-22T23:08:42 < mawk> get a preempt rt kernel and use a fifo scheduling class
2022-01-22T23:08:51 < mawk> do not put the maximum priority
2022-01-22T23:08:57 < mawk> or you'll starve the kernel
2022-01-22T23:10:06 < mawk> it's been two days I haven't slept Steffann 
2022-01-22T23:10:07 < mawk> do something
2022-01-22T23:10:15 < mawk> my sleeping aids have run out
2022-01-22T23:10:25 < BrainDamage> preemption still gives you a good way there
2022-01-22T23:10:31 < mawk> yes
2022-01-22T23:10:40 < BrainDamage> you don't need full rt unless you need strict timing
2022-01-22T23:10:42 < mawk> but you need a kernel compiled with that option
2022-01-22T23:10:51 < mawk> I'm not sure what debian default is
2022-01-22T23:10:56 < BrainDamage> get melatonin, it's off the counter in europe
2022-01-22T23:11:02 < mawk> I have it
2022-01-22T23:11:06 < mawk> I take melatonin and cbd
2022-01-22T23:11:11 < mawk> but I don't count them as sleeping aids
2022-01-22T23:11:26 < mawk> it does close to nothing for severe insomnia
2022-01-22T23:11:36 < mawk> in France benadryl and doxylamine are OTC but not here
2022-01-22T23:11:53 < Laurenceb> 0
2022-01-22T23:11:53 < Laurenceb> Linux Kernel implements two separate priority ranges -
2022-01-22T23:11:54 < Laurenceb> Nice value: -20 to +19; larger nice values correspond to lower priority.
2022-01-22T23:11:55 < Laurenceb> Real-time priority: 0 to 99; higher real-time priority values correspond to a greater priority
2022-01-22T23:11:59 < Laurenceb> arggg why lunix why
2022-01-22T23:12:07 < mawk> use realtime Laurenceb 
2022-01-22T23:12:11 < mawk> I just told you
2022-01-22T23:12:16 < mawk> and not 99
2022-01-22T23:12:19 < mawk> use 95
2022-01-22T23:13:23 < BrainDamage> nice is completely overridden by rt
2022-01-22T23:13:47 < BrainDamage> nice is for reg processes, if a process requires rt it's higher than anything else and only handled by rt
2022-01-22T23:13:57 < Laurenceb> this seems to make a difference
2022-01-22T23:14:14 < Laurenceb> swapping 48 to 55 halved the overrun rate
2022-01-22T23:14:14 < mawk> inb4 laurence uses prio 99
2022-01-22T23:14:28 < Laurenceb> I'll try 75
2022-01-22T23:14:28 < BrainDamage> do you acquire rt permissions?
2022-01-22T23:14:34 < Laurenceb> no
2022-01-22T23:14:38 < BrainDamage> ...
2022-01-22T23:14:47 < mawk> check return code of chrt
2022-01-22T23:15:04 < Laurenceb> it changed the process
2022-01-22T23:15:14 < mawk> use setprio yourself
2022-01-22T23:15:16 < mawk> in the process
2022-01-22T23:15:17 < BrainDamage> mawk: get valerian tea, it's a GABA modulator

2022-01-22T23:15:24 < BrainDamage> you can even get a liter
2022-01-22T23:15:43 < Laurenceb> mawk: I sucessfully changed it to 55
2022-01-22T23:15:44 < mawk> and I won't seize to death if I discontinue?
2022-01-22T23:17:43 < BrainDamage> no, but it's a depressant, like you know, opioids
2022-01-22T23:18:15 < mawk> I'm immune to opioids don't worry
2022-01-22T23:20:45 < mawk> I'll try valerian maybe
2022-01-22T23:21:12 < BrainDamage> the bonus point is that you also get a benzo like effect
2022-01-22T23:23:51 < Steffann> Try ... some sleep, mawk
2022-01-22T23:25:07 < mawk> that's what I do Steffann 
2022-01-22T23:25:12 < mawk> but it doesn't work
2022-01-22T23:25:25 < mawk> I stay lying in the bed for 8 hours and nothing happens
2022-01-22T23:25:28 < Steffann> What have you been up to?
2022-01-22T23:25:37 < mawk> lol
2022-01-22T23:25:39 < mawk> not much
2022-01-22T23:25:45 < mawk> I just don't have otc sleep aid anymore
2022-01-22T23:25:54 < mawk> I buy it in France and bring it back
2022-01-22T23:26:05 < mawk> since snob dutch don't sell it
2022-01-22T23:26:15 < Steffann> Sleep aids..
2022-01-22T23:26:18 < mawk> yes
2022-01-22T23:26:20 < mawk> OTC
2022-01-22T23:26:23 < mawk> mere antihistaminics
2022-01-22T23:26:27 < mawk> very safe, no addiction
2022-01-22T23:26:35 < mawk> safe enough to be without prescription
2022-01-22T23:26:48 < Steffann> Yeah very safe, no addiction, can't sleep without 
2022-01-22T23:27:00 < mawk> that's not the same as addiction
2022-01-22T23:27:03 < mawk> that's rebound effect
2022-01-22T23:28:03 < Steffann> So buy some slaap lekker tea
2022-01-22T23:28:15 < mawk> none of the woo works usually
2022-01-22T23:28:21 < mawk> tea, chinese medicine, whatever
2022-01-22T23:28:30 < mawk> real molecules from real medication, that's what works
2022-01-22T23:28:33 < mawk> I'm a man of science
2022-01-22T23:30:26 < BrainDamage> just because it's tea it doesn't mean it doesn't do nothing, you should know well
2022-01-22T23:30:32 < BrainDamage> try making stramonium tea
2022-01-22T23:30:44 < BrainDamage> or wintergreen tea
2022-01-22T23:32:18 < BrainDamage> 1ml of wintergreen oil has 2g of salycilic acid for example
2022-01-22T23:34:03 < BrainDamage> the main difference of medicine is that you get that purified so you won't get the other stuff
2022-01-22T23:34:18 < BrainDamage> which is generally a good idea to avoid secondary effects
2022-01-22T23:34:25 < BrainDamage> but if you're desperate to sleep ...
2022-01-22T23:36:11 < Steffann> Why you even use this stuff in the first place mr mawk?
2022-01-22T23:36:22 < mawk> because I couldn't sleep
2022-01-22T23:36:33 < Steffann> Why not?
2022-01-22T23:36:43 < mawk> no idea
2022-01-22T23:36:47 < mawk> a lot of people have insomnia
2022-01-22T23:37:12 < BrainDamage> and his neutrotransmitter are likely fucked up by opioid abuse
2022-01-22T23:37:17 < mawk> and I'm too immune to opiates to get sleepy from them
2022-01-22T23:37:20 < mawk> noooo
2022-01-22T23:37:32 < mawk> only μ-opiate receptors have been downregulated
2022-01-22T23:37:45 < mawk> but daily supplemeted by methadone to keep levels constant
2022-01-22T23:37:50 < mawk> so my brain is pristine
2022-01-22T23:37:50 < BrainDamage> just pray you'll never need surgery :p
2022-01-22T23:37:57 < mawk> lol
2022-01-22T23:38:09 < Xogium> mawk: you ever tried melatonin ? I don't know, maybe it's not useful… at least for me it sure did work. Too much in fact. I took the minimal dose of it and I was out for several hours. Good ? Nop. I slept so much that when I woke up I was even more tired lol
2022-01-22T23:38:19 < mawk> yes I tried it
2022-01-22T23:38:23 < mawk> but it's not a sleeping aid
2022-01-22T23:38:31 < mawk> it's jetlag aid 
2022-01-22T23:38:39 < mawk> a circadian clock resetter
2022-01-22T23:38:39 < Steffann> Isnt insomnia a side effect of methadone (abuse)?
2022-01-22T23:38:43 < mawk> but not sedative
2022-01-22T23:38:50 < mawk> only when you're new to it Steffann 
2022-01-22T23:38:54 < Xogium> hrmm. Yeah. That explains why it worked on me then
2022-01-22T23:39:04 < mawk> ah
2022-01-22T23:39:07 < mawk> I misread
2022-01-22T23:39:18 < mawk> no, a side effect is sleepiness when you're new to it
2022-01-22T23:39:26 < mawk> when you're experienced it just does nothing
2022-01-22T23:39:40 < mawk> but certainly not insomnia, if anything it should help sleep
2022-01-22T23:39:53 < Steffann> "Chronic methadone abuse can often result in insomnia, which can lead to a host of problems."
2022-01-22T23:40:00 < mawk> lies
2022-01-22T23:40:03 < mawk> lies lies lies
2022-01-22T23:40:15 < Steffann> Random Google results. But I trust doctor google
2022-01-22T23:40:18 < mawk> I'm pretty sure it's from the withdrawals that they say it anyway
2022-01-22T23:40:26 < mawk> not methadone directly
2022-01-22T23:40:34 < mawk> and I'm not even abusing it
2022-01-22T23:40:37 < mawk> just a little
2022-01-22T23:40:40 < mawk> it's littlebuse
2022-01-22T23:40:47 < Steffann> https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2874989/ Read that for me please.
2022-01-22T23:41:16 < mawk> these patients have a dose way higher than me
2022-01-22T23:41:17 < Xogium> but… yeah ither way I'm never touching melatonin again. That was awefull. I couldn't sleep but was getting beyond tired, so I tried that. I shouldn't have :p
2022-01-22T23:41:21 < mawk> maybe at these it does insomnia
2022-01-22T23:41:27 < mawk> but anyway my insomnia predates methadone
2022-01-22T23:42:31 < Xogium> I kinda let my body do whatever it wants with the circadian clock these days
2022-01-22T23:43:08 < BrainDamage> you have the perfect excuse you're blind
2022-01-22T23:43:29 < BrainDamage> light and meals play a major role in circadian rhythm setting
2022-01-22T23:43:44 < Xogium> trying to keep it at a 24-hours schedule is also a bad idea, that much I learned while in school. I went without sleep for about 3 days. Then I fell asleep during a class. The teacher made me stand up from my chair and held me, and I didn't wake up
2022-01-22T23:44:05 < mawk> >Twenty-three of 71 participants tested positive for benzodiazepines on night one. Of those who tested negative for benzodiazepines or did not receive toxicology on night one, 4 of 51 tested positive on night two. Other positive urinalyses were for tetrahydrocannabinol (24/71 on night one and 5/51 new positives on night two), cocaine (17/71 on nigh
2022-01-22T23:44:05 < mawk> t one and 3/57 new positives on night two), and opiates other than methadone (12/71 on night one and 1/62 new positives on night two).
2022-01-22T23:44:11 < mawk> here's your explanation Steffann 
2022-01-22T23:44:16 < mawk> these guys are whacked on something else
2022-01-22T23:45:07 < Xogium> I slept so deep they thought I was unconscious and were on the verge of calling for an ambulance
2022-01-22T23:45:55 < mawk> also the study doesn't conclude
2022-01-22T23:45:58 < mawk> weirdly
2022-01-22T23:46:13 < mawk> they only conclude that unattented polysomnograph is doable with addicts
2022-01-22T23:47:43 < Xogium> but my record of going without sleep was 7 days. No nap possible, no resting for even 30 seconds. I just couldn't manage to fall asleep at night because my body was like, time to be awake buddy, then during the day I was mega tired, yet unable to sleep because my body was still on time to be awake
2022-01-22T23:47:46 < BrainDamage> my guess is that they were strapped for funding and pushed out a feasibility study
2022-01-22T23:47:58 < BrainDamage> so that they could ask for money with it
2022-01-22T23:48:00 < Laurenceb> ok this is weird
2022-01-22T23:48:13 < mawk> yeah
2022-01-22T23:48:28 < Laurenceb> I ssh into device, and log a screen session, but I cant seem to capture network disconnections
2022-01-22T23:48:31 < Xogium> after 7 days of that, I felt pretty much like a zombie. I don't remember anything other than being tired actually. That, and litterally falling asleep while standing in a corridor
2022-01-22T23:48:43 < mawk> did you have hallucinations Xogium ?
2022-01-22T23:48:46 < Laurenceb> but screen usually reconnects automatically
2022-01-22T23:48:51 < Xogium> yep plenty
2022-01-22T23:48:51 < Laurenceb> wtf is going on
2022-01-22T23:48:52 < mawk> after 8 days of no sleep I had pretty hardcore psychosis
2022-01-22T23:49:04 < mawk> I got sent in a psychiatric hospital for a month
2022-01-22T23:49:08 < BrainDamage> I got hallucinations only after 3 days
2022-01-22T23:49:09 < Laurenceb> my server can see the diconnections
2022-01-22T23:50:05 < Xogium> yeah honestly it was…
2022-01-22T23:50:22 < mawk> I was hearing people talking about me behind the walls, cameras everywhere, my phone tapped, and at the end insects, insects everywhere
2022-01-22T23:50:37 < mawk> I was making a fire in my trashcan when I was found
2022-01-22T23:50:40 < Xogium> in a way I'm glad I couldn't have visual ones, the ones I could hear were insane enough already
2022-01-22T23:51:06 < mawk> because I read fumigation was scaring insects
2022-01-22T23:51:20 < Xogium> huh huh bad idea I reckon
2022-01-22T23:52:05 < Xogium> but that's the whole issue with this stupid clock going wild. If it decides that I'm still awake at 3 in the morning, there's nothing I can do about it
2022-01-22T23:52:31 < Xogium> it won't send the signal to go to sleep until it thinks its time
2022-01-22T23:53:11 < Xogium> so I gradually get out ofsync, then at some point resync, then drift again
2022-01-22T23:53:55 < Xogium> but the absolute worse for others is when my clock is completely reversed
2022-01-22T23:54:09 < Xogium> not too much for me, I get good sleep by that time too… Just during the day
2022-01-22T23:55:48 < Xogium> but yeah… trying to control it to fit into the social norm and have a 24-hours schedule like everyone else is the worst thing I ever did. Permanent jet lag
2022-01-22T23:56:17 < Steffann> Can your caregiver hear your speech thingy or don't you use it all the time Xogium ?
2022-01-22T23:56:31 < Xogium> oh I use it all the time, over headphones
2022-01-22T23:56:43 < Steffann> Just curious if I have to mind my words or not 😛
2022-01-22T23:56:50 < Xogium> lol no no
2022-01-22T23:57:06 < Xogium> no monitor either, isn't that cool
2022-01-22T23:57:13 < Steffann> Hah
2022-01-22T23:58:13 < Xogium> if I was even a tiny bit interested in porn, I'd have the perfect setup that noone would ever know what I'm checking out
2022-01-22T23:58:16 < Xogium> :p
2022-01-22T23:58:41 < fenugrec> is there an asciiart converter for braille displays i wonder
2022-01-22T23:59:04 < Steffann> Awh, no ASMR porn for you?
2022-01-22T23:59:04 < Xogium> fenugrec: how do you mean ?
2022-01-22T23:59:33 < BrainDamage> ever tried text adventures Xogium ?
2022-01-22T23:59:45 < Xogium> Steffann: hah nop. It's fankly weird but then again so's regular porn. I mean I guess it only works good if you have eyes
2022-01-22T23:59:45 < fenugrec> render pixel art directly on the display, i.e. not based on the shape of say the letter L or a dash
2022-01-22T23:59:52 < Xogium> *frankly
--- Day changed Sun Jan 23 2022
2022-01-23T00:00:23 < Xogium> BrainDamage: hmm yeah… I think so. A while back, I think you even sent me some
2022-01-23T00:01:04 < BrainDamage> Steffann: fun thing, ASMR works on me, but I don't understand why people fuss so much about it
2022-01-23T00:01:24 < Xogium> fenugrec: don't believe there is… braille itself is based on the letters and symbols. You could probably make strange symbols with no meaning, but in all case you'd have only 8 dots possible per cell
2022-01-23T00:03:26 < Xogium> speaking of which I finally managed to contact the guy that I got my display from. He explained how to open it up, should I want to do the cleaning
2022-01-23T00:04:17 < Xogium> you've got to unscrew the entire back panel off, then you can lift the whole top cover. Carefully though. The braille pins are spring-loaded. You don't want 640 braille pins pinging off somewhere in the whole place
2022-01-23T00:04:47 < Xogium> then carefully take them out of each cell and use IPA if you have, or for optimal result, ultrasonic bath
2022-01-23T00:05:47 < Xogium> and then the fun part, putting them back in the cells… In the correct order
2022-01-23T00:07:08 < Xogium> yeah cause they have an order… The longest pins are dot 7 and 8, 3 and 6 are slightly smaller, etc
2022-01-23T00:07:56 < Xogium> in fact when you get them in the cell they end up showing at the same height but it's just that on top they are at the same level, below they get longer and longer
2022-01-23T00:11:33 < Xogium> I wonder if I could actually get my hands on an ultrasonic bath
2022-01-23T00:12:00 < BrainDamage> china sells small ones for 10-20 bucks
2022-01-23T00:12:08 < BrainDamage> they should be able to fit the cells nicely
2022-01-23T00:12:33 < BrainDamage> mine is approx 20cmx10cmx5cm
2022-01-23T00:13:07 < BrainDamage> 20cm is approx the distance between q and p on your keyb
2022-01-23T00:13:12 < BrainDamage> to get an idea
2022-01-23T00:15:43 < mawk> asmr is highly uncomfortable
2022-01-23T00:16:14 < mawk> so I guess it works but badly
2022-01-23T00:16:24 < Xogium> BrainDamage: not too bad… if they aren't made badly that is
2022-01-23T00:16:26 < mawk> magic sounds that make you want to pierce your eardrums
2022-01-23T00:16:59 < BrainDamage> mawk: here they mostly send shivers up my spine
2022-01-23T00:17:02 < Steffann> Luckily where not all like you mawk.
2022-01-23T00:17:11 < Steffann> We're*
2022-01-23T00:17:52 < mawk> it makes me the same feeling as when I'm 3 days into withdrawal and I can't stop moving my legs for more than 5s otherwise an insufferable tension builds up
2022-01-23T00:17:54 < Steffann> If we were we would talk about drugs and math all day long.
2022-01-23T00:17:57 < BrainDamage> Xogium: there's not so much to get wrong there, it's a metal tray with a piezoelectric puck glued on, and an oscillator
2022-01-23T00:18:29 < mawk> what's wrong with maths
2022-01-23T00:18:46 < BrainDamage> but depending on how tight the lid fits, you might get nasty audible sounds
2022-01-23T00:19:00 < BrainDamage> so I recomend operating it in another room
2022-01-23T00:19:09 < BrainDamage> they are pretty obnoxious
2022-01-23T00:19:32 < mawk> my cat hates the noise
2022-01-23T00:19:37 < mawk> of ultrasonic bath
2022-01-23T00:21:32 < Xogium> hmm
2022-01-23T00:22:09 < Xogium> yeah I'll definitely keep that in mind, about the annoying sounds
2022-01-23T00:23:57 < Xogium> I definitely won't need a big one so that's at least that, the pins are rather small

2022-01-23T14:57:33 < karlp> usb hub attached to it no longer worked this morning
2022-01-23T14:57:48 < karlp> unplugged the usb cable from the pc to the monitor and replugged it. screen black won't turn on anymore
2022-01-23T14:57:50 < karlp> boooo
2022-01-23T15:01:10 < karlp> eird....
2022-01-23T15:01:19 < karlp> unpluged enough and it works again.
2022-01-23T15:01:20 < karlp> spooky
2022-01-23T15:05:26 < karlp> oh shit, touching it is giving me glitchy greens
2022-01-23T15:05:31 < karlp> guess it's shopping time :)
2022-01-23T15:05:43 < jpa-> bad cable?
2022-01-23T15:06:21 < karlp> well, it's a big heavy duty dvi cable I'v used for years without touching it, it's onyl the usb hub on the side of it that's been getting touched a lot
2022-01-23T15:06:40 < karlp> having the usbhub connected would make it go black a lot
2022-01-23T15:07:49 < jpa-> ah
2022-01-23T15:07:54 < jpa-> i expected it to be fancy usb-c
2022-01-23T15:08:29 < karlp> nah, this monitor is older than that.
2022-01-23T15:08:42 < karlp> it has a usb3-fatB upstream port 
2022-01-23T15:08:58 < karlp> and I have dvi to this monitor and hdmi to the other,
2022-01-23T15:09:05 < karlp> and this monitor has hdmi from the playstation
2022-01-23T15:51:28 < karlp> oops, guess my memory map is wrong.  cpu2 thinks i'm security attacking
2022-01-23T16:44:14 < fenugrec> jpa-, is your CH2 probe differential or what ?
2022-01-23T16:51:27 < jpa-> fenugrec: yeah
2022-01-23T16:51:59 < jpa-> (for anyone interested, increasing the gate resistor on high side FETs helped  https://jpa.kapsi.fi/stuff/pix/waveforms7.png )
2022-01-23T16:53:37 < fenugrec> why does it take so long for Q1 Vgs to fall back to 0 ? is the gate driver that asymetric ?
2022-01-23T16:53:50 < fenugrec> it spends way more time on the plateau
2022-01-23T16:55:41 < jpa-> i have more gate resistance on high side FETs to try to avoid induced turn-on due to the drain-gate capacitance
2022-01-23T16:56:28 < jpa-> these fets have about as much Cdg as Cgs so when the drain voltage on low side FET rises rapidly, it tends to turn on, which caused the problems in the first image
2022-01-23T16:56:54 < fenugrec> sure, but the rising / falling edges of that CH2 trace or quite different
2022-01-23T16:57:17 < fenugrec> yea these power fets have massive input capacitance
2022-01-23T16:57:36 < jpa-> input capacitance is ok, but the gate-drain capacitance is annoying
2022-01-23T16:58:36 < fenugrec> hm, Cdg varies according to Vds so maybe that's why the falling edge is slower ? not quite awake yet

2022-01-23T17:01:27 < jpa-> fenugrec: good question on the asymmetry, per the specs it should fall faster than it rises
2022-01-23T17:01:31 -!- mode/##stm32 [+b Laurenceb!*@*] by englishman
2022-01-23T17:01:31 < ventYl> :))
2022-01-23T17:06:59 < jpa-> fenugrec: maybe it is because the plateau is at the 2.5V Vgs_th voltage, and the driver is pushing Vgs up to 12V - so when going up, there is 9.5V over the gate resistor, but when going down, there is only 2.5V over it
2022-01-23T17:07:44 < jpa-> so one could expect 4x longer plateau, but equal time for the total exponential curve
2022-01-23T17:09:01 < jpa-> the datasheet suggests putting a diode in parallel with the gate resistor, and it certainly makes it faster - i just don't have a small enough to sit on top of the 0603 resistor
2022-01-23T17:09:29 < fenugrec> sounds plausible. It's true the exponential segments with Vgs > th is longer on the rising edge; that fits
2022-01-23T17:10:51 < jpa-> the plateau is again due to Cdg acting against the driver - if it was just Cgs it would rise smoothly
2022-01-23T17:11:02 < fenugrec> anyway, at least your probing setup is probably ok - second capture has a lot less HF ringing which could've been just inductive pickup
2022-01-23T17:12:13 < jpa-> the 65 MHz ringing in the first capture indeed coupled to everything, so it was hard to pinpoint where it was coming from

2022-01-23T23:26:46 < karlp> (absolutely zero power saving at this point though, so it's useless for anything real yet)
2022-01-23T23:27:35 < karlp> zyp: this was pretty gross though, but I wanted to fix it rather than ahck around that right now: https://github.com/karlp/laks/commit/9abade1c4e685a0cbba0c717eb2ff3b836cc631c
2022-01-23T23:28:13 < karlp> pretty pleased with this trickery though... thank you st for using old style manual include guards.
2022-01-23T23:28:29 < karlp> the debugging stuff theyhave is the only bit that was really tied to HAL stuff.

2022-01-23T23:31:50 < zyp> karlp, unless I broke it in v2, linker script overriding should already work
2022-01-23T23:32:15 < zyp> works for arcin: https://cgit.jvnv.net/arcin/tree/SConstruct
2022-01-23T23:35:50 < zyp> you can probably change the if expression to «if 'LINK_SCRIPT' in kwargs:»
2022-01-23T23:36:01 < zyp> since that would imply you want a custom ld
2022-01-23T23:37:22 < zyp> also, longer term I want to do something more elaborate with the linker script generator eventually, so you can just specify stuff like bootloader regions and have it generate the right thing
2022-01-23T23:43:56 < Steffann> As long as its easy to exclude things that doesn't sound bad
2022-01-23T23:44:27 < Steffann> Newt does it badly imho. But then newt documentation is so-so 
2022-01-23T23:46:04 < Steffann> Newt/mynewt uses yml and generators as well, but overriding things in a simple manner is a pain
2022-01-23T23:47:28 < zyp> yeah, being able to use a custom linker script should still be possible
2022-01-23T23:51:50 < qyx> Steffann: sre you a mynewt pro?
2022-01-23T23:51:58 < karlp> zyp, it "works" but it adds a dep on the laks/build dir path
2022-01-23T23:53:44 < Steffann> Qyx I messed around with it a bit and so far I don't like it qyx 
2022-01-23T23:54:49 < qyx> ok you are a step forward, that was indeed my next question
2022-01-23T23:57:04 < Steffann> I only tried it because of nimble ble stack
2022-01-23T23:59:35 < Steffann> I heard ventyl OS is great 😋

2022-01-24T00:09:20 < Steffann> Mynewt does work, but im not sure yet I really like it. Already felt like I had to use hacky configs to get rid of the logging and bootloader 
2022-01-24T00:09:39 < Steffann> And something basic like changing compiler flags 
2022-01-24T00:09:41 < Steffann> Meh

2022-01-24T00:10:59 < karlp> not just using the nrf stack then?

2022-01-24T00:13:26 < Steffann> I wanted to make a ble remote for my camera. The softdevice isn't really "optimized" for the way the services+characteristics are organised.

2022-01-24T00:18:49 < Steffann> Oh you don't use the OS part of laks (is that even still a thing?l

2022-01-24T00:28:05 < Steffann> Yeah I read that
2022-01-24T00:40:20 < zyp> I ripped out the old multithreading stuff in v2, it weren't very useful in its current state
2022-01-24T00:41:44 < zyp> might add it back later, because while coroutines are great, they aren't preemptive
2022-01-24T00:42:15 < zyp> but so far laks never really had proper preemptive multithreading anyway

2022-01-24T13:21:38 < hiovoltage> do you know what is the type of medical temperature probes?
2022-01-24T13:24:29 < mawk> the rectal type?
2022-01-24T13:24:52 < hiovoltage> yeap rectal or surface doesnt matter
2022-01-24T13:24:57 < mawk> I wouldn't know why a regular thermocouple wouldn't work
2022-01-24T13:25:00 < mawk> well surface is IR
2022-01-24T13:25:19 < mawk> the rest are just thermocouples I guess
2022-01-24T13:25:33 < mawk> you also have tympanic thermometers but I don't know what they use
2022-01-24T13:25:34 < mawk> maybe IR too
2022-01-24T13:25:46 < mawk> because touching your eardrum with a metal rod might not be a good idea
2022-01-24T13:27:02 < hiovoltage> surface probe and rectal probe have same connector. Their type should be same i guess
2022-01-24T13:27:12 < mawk> what do you call surface probe
2022-01-24T13:27:22 < mawk> to get surface temperature you use IR thermometer I suppose
2022-01-24T13:27:35 < mawk> using a regular thermocouple thermometer on the surface of your skin isn't really a good idea
2022-01-24T13:27:39 < mawk> it needs to be fully "inside" the body
2022-01-24T13:27:43 < mawk> under the armpit, under the tongue
2022-01-24T13:27:49 < mawk> you can't have exposed metal to the air
2022-01-24T13:30:41 < PaulFertser> I tried using ds18b20 under the armpit, the results were withing few .1C to what I measured with a regular liquid metal medical thermometer.
2022-01-24T13:31:14 < mawk> under the tongue is the most accurate whilst being the least embarrassing imo
2022-01-24T13:31:19 < mawk> I just sterilize in alcohol before and after
2022-01-24T13:31:25 < mawk> you add 0.5°C to the measure to get body temp
2022-01-24T13:31:39 < mawk> the absolute best is tympanic temperature
2022-01-24T13:31:52 < mawk> it doesn't embarras the patient and it's as precise as the rectal temp
2022-01-24T13:32:18 < mawk> but you need a special thermometer for it
2022-01-24T13:32:46 < PaulFertser> The question is why you need the absolute temperature to be that accurate.
2022-01-24T13:32:51 < mawk> under the tongue you must not have drank hot or cold beverage 10 minutes before
2022-01-24T13:33:03 < mawk> well
2022-01-24T13:33:14 < mawk> between 41°C and 43°C, there's life or death
2022-01-24T13:33:39 < mawk> especially for a child
2022-01-24T13:34:01 < PaulFertser> Isn't it like you measure 41 by any means and call ambulance right away?
2022-01-24T13:34:13 < mawk> ah, maybe in theory
2022-01-24T13:34:21 < mawk> I didn't do it when my gf had 41°C from covid
2022-01-24T13:34:27 < hiovoltage> i found this : https://www.cablesandsensors.com/products/philips-compatible-disposable-temperature-probe-21091a?variant=33809881544
2022-01-24T13:34:29 < karlp> for little kids it was 39? straight to hospital.
2022-01-24T13:34:35 < mawk> she wasn't delirious
2022-01-24T13:34:42 < hiovoltage> rectal type and site says NTC
2022-01-24T13:34:58 < mawk> so not thermocouple hiovoltage 
2022-01-24T13:35:12 < mawk> NTC is slower to come to measure I think
2022-01-24T13:35:19 < mawk> but probably not by a large margin

2022-01-24T13:36:00 < qyx> I would say most of todays high precision and most stable sensors are NTC
2022-01-24T13:36:08 < hiovoltage> manufacturer says accuracy is 0.1 if temp  range is 37-42
2022-01-24T13:36:21 < qyx> I have not seen any decent Pt100/Pt1000 recently, because industry doesn't need it
2022-01-24T13:36:32 < mawk> the thermometer in my secret drug manufacturing lab is a thermocouple, it's to 0.1°C
2022-01-24T13:36:33 < qyx> hiovoltage: TE 55xxx maybe?
2022-01-24T13:36:51 < qyx> there is no point in using thermocouples for 40 °C
2022-01-24T13:37:01 < qyx> fuk thermocouples

2022-01-24T13:37:07 < mawk> it's just two pieces of metal
2022-01-24T13:37:11 < mawk> how expensive can it be
2022-01-24T13:37:53 < qyx> for a thermocouple you need a CJC
2022-01-24T13:38:17 < qyx> and the precision of the thermocouple depends on the precision of CJC, including junction to sensor coupling
2022-01-24T13:38:50 < qyx> for low ohmic sensors you need 4 wires
2022-01-24T13:39:08 < qyx> so the easiest and most accurate in the end is 10k+ NTC
2022-01-24T13:39:22 < mawk> last time I tried using a NTC it took minutes to come to temperature
2022-01-24T13:39:37 < benishor> hmm, I can't get my bluepill (stm32f103) to usb enumerate
2022-01-24T13:39:48 < benishor> I created the most basic usb example
2022-01-24T13:39:58 < hiovoltage> yeap i am using thermocouple for high temp like 1200C. Now i need to use medical rectal probe. i have never used it before
2022-01-24T13:40:26 < benishor> with the cubeide and flashed it on the board
2022-01-24T13:40:30 < benishor> reconnected the usb 
2022-01-24T13:40:45 < benishor> and I keep getting: https://pastebin.com/mmbZDbVc
2022-01-24T13:40:55 < qyx> NTC/R25=2.252K
2022-01-24T13:40:58 < qyx> what the hell is that value
2022-01-24T13:41:14 < qyx> some legacy shit probably
2022-01-24T13:41:30 < mawk> why are you not buying one hiovoltage ?
2022-01-24T13:42:15 < hiovoltage> mawk: i already have:)  i just want to ask if you have more information
2022-01-24T13:42:29 < mawk> a
2022-01-24T13:42:42 < mawk> if you don't like prostate massage exam using it under the tongue is fine too
2022-01-24T13:42:46 < mawk> add 0.5°C
2022-01-24T13:42:53 < mawk> take 3 measurements, take max of the three
2022-01-24T13:42:59 < mawk> and don't drink anything before
2022-01-24T13:44:15 < mawk> it must be firmly under the tongue, right next to the tongue frenulum
2022-01-24T13:47:22 < hiovoltage> actually we will use it inside belly of rat :)
2022-01-24T13:48:56 < hiovoltage> still looking for NTC/R25=2.252K this weird value

2022-01-24T13:51:12 < mawk> ah I guess the rat won't mind a prostate massage
2022-01-24T13:51:42 < mawk> why this exact value hiovoltage ?
2022-01-24T13:52:31 < kakium69> are you guise pleasuring rats?
2022-01-24T13:52:34 < mawk> you can add a resistor in series with it to shift it so that the R25 is at 2252Ω I guess
2022-01-24T13:52:39 < mawk> yes kakium69 hiovoltage is
2022-01-24T13:52:59 < kakium69> nice
2022-01-24T13:54:11 < mawk> also I don't know why you want such a precise value hiovoltage 
2022-01-24T13:54:19 < mawk> you won't get better than ±2% accuracy I guess
2022-01-24T13:54:37 < benishor> apparently the bluepill's board usb pullup resistor is 10K
2022-01-24T13:54:46 < benishor> at least for the batch I have
2022-01-24T13:54:50 < benishor> can this pose a problem? 
2022-01-24T13:54:52 < mawk> yes benishor that makes it so that it doesn't work on some computers
2022-01-24T13:54:57 < mawk> you can replace it
2022-01-24T13:55:05 < mawk> or replace your computer
2022-01-24T13:55:06 < benishor> I seem to recall there was a need for 1.5K or something around that value
2022-01-24T13:55:33 < benishor> yes mawk, it's way cheaper and faster to replace my computer
2022-01-24T13:55:39 < hiovoltage> but manufacturer says it gives 0.1 accuracy and medical devices show that accuracy. I think they can not show wrong value
2022-01-24T13:55:42  * benishor throws his unit out the window
2022-01-24T13:56:01 < mawk> hiovoltage: I think they just calibrate it
2022-01-24T13:56:34 < hiovoltage> yes ofcourse calibration is important part
2022-01-24T13:57:36 < mawk> aren't you going to lacerate the rat's insides if you use a human size probe hiovoltage ?
2022-01-24T13:58:55 < hiovoltage> doctors are already using these sensors for rats and humans
2022-01-24T13:59:20 < mawk> I guess a rat is stretchy then
2022-01-24T13:59:30 < mawk> I hope they sterilize the probe before going from rat to human

2022-01-24T14:23:26 < karlp> right, but was your "NTC prob" a 30g block of metal or something?
2022-01-24T14:23:46 < karlp> either way, definitely not a tech problem, but a device problem

2022-01-24T14:42:47 < mawk> then probably not that

2022-01-24T19:02:35 < Steffanx> Does any Russian (except for putin&co) actually care? 
2022-01-24T19:10:59 < PaulFertser> Steffanx: there's plenty of official propaganda, I think they are constantly pushing the idea that russia's trying to "protect itself" against possible "nato aggression" and for that they are negotiating with the USA.
2022-01-24T19:11:18 < PaulFertser> Steffanx: it's not like they mean that russia should invade ukraine or something.
2022-01-24T19:11:34 < PaulFertser> Steffanx: other news sources are of course telling different story. I think many people care.
2022-01-24T19:21:43 < Steffanx> PaulFertser:  Oh, that's not that much different from what we hear here. Except that it's always " we do [x] because Russia does [y]"
2022-01-24T19:22:16 < Steffanx> I mean care as in really think the nato is a threat. 
2022-01-24T19:23:04 < PaulFertser> Steffanx: official media says nato is a threat to russia, yes. About the same as it was during the soviet times I guess.
2022-01-24T19:23:52 < BrainDamage> well, nato is a threat to russia same way russia is a threat to nato
2022-01-24T19:24:15 < BrainDamage> but there's a difference between a passive threat and an active one
2022-01-24T19:24:32 < BrainDamage> however, not to say that nato doesn't do its share of underhanded tactics
2022-01-24T19:25:10 < BrainDamage> see eg us funding talibans
2022-01-24T19:25:21 < BrainDamage> something that backfired spectacularly
2022-01-24T19:25:30 < fenugrec> englishman, nop never heard of that
2022-01-24T19:25:42 < BrainDamage> the whole situation in syria is now a proxy war
2022-01-24T19:27:07 < ventYl> in some sense, cold war still goes on
2022-01-24T19:27:14 < ventYl> with all those proxy wars
2022-01-24T19:27:39 < Steffanx> We're in big trouble when Russia decides to close the natural gas pipe lines. Dutchland reserves are historically low and the prices already sky high
2022-01-24T19:28:28 < Steffanx> So they better keep it friendly 
2022-01-24T19:30:09 < ventYl> quality soviet pottery, fell off my work desk straight onto floor. no damage
2022-01-24T19:30:09 < fenugrec> just import coal from china instead
2022-01-24T19:30:11 < fenugrec> problem solved
2022-01-24T19:30:17 < ventYl> i should check floor tiles probably
2022-01-24T19:31:18 < ventYl> well, I guess that if there were nuclear reactors still running, europe could import fuel from wherever and don't care much about gas for most part
2022-01-24T19:31:50 < BrainDamage> plenty of uranium mines in africa to exploit
2022-01-24T19:31:50 < Steffanx> My stove doesn't work on coal fenugrec 
2022-01-24T19:32:01 < Steffanx> Neither does the central heating
2022-01-24T19:32:19 < BrainDamage> but I suspect that the dependance from oil and gas isn't completely accidental
2022-01-24T19:32:33 < BrainDamage> as in, there's political interests in keeping such
2022-01-24T19:32:50 < jpa-> Steffanx: time to upgrade to non-planet-destroying tech
2022-01-24T19:32:52 < ventYl> at which side?
2022-01-24T19:33:35 < PaulFertser> Steffanx: weren't there enough years since the Boeing downing to do something to diversify energy sources properly?
2022-01-24T19:34:01 < ventYl> PaulFertser: one way or another, this thing will be quite interesting. how it turns out. it may falsify some expectations
2022-01-24T19:34:25 < Steffanx> PaulFertser: no.
2022-01-24T19:35:08 < Steffanx> Our electricity infrastructure cant keep up with all the solar panels fields and wind turbines 
2022-01-24T19:35:22 < Steffanx> Nor with the solar panels on roof tops
2022-01-24T19:39:43 < PaulFertser> Steffanx: you can use electricity to cook food, and diesel for home heating. And coal for central heating systems.
2022-01-24T19:40:33 < PaulFertser> ventYl: I can't think about any war as something interesting :/
2022-01-24T19:41:15 < BrainDamage> coal heating was outlawed here
2022-01-24T19:41:51 < BrainDamage> partially because there's no economical small scale ways to desulphur and cleanup coal
2022-01-24T19:42:07 < bitmask> awww, I set up my first smart home thing, bought 5 sonoff smart outlets :P

2022-01-24T19:44:10 < ventYl> PaulFertser: well, the war is not the interesting part. that will suck. interesting will be everything, which will/won't lead to it

2022-01-24T19:48:33 < mawk> pour a bit of diesel on your steak and crack a match

2022-01-24T19:49:31 < mawk> ah really
2022-01-24T19:49:39 < mawk> I don't eat a lot of meat either but just because I'm poor
2022-01-24T19:49:58 < ventYl> you spend all your money on funny stuff?
2022-01-24T19:50:14 < PaulFertser> Diesel is much harder to light up than petrol.
2022-01-24T19:50:42 < ventYl> you can compress your food, diesel will then self-ignite
2022-01-24T19:52:09 < mawk> just around 600€ on funny stuff ventYl 
2022-01-24T19:52:20 < mawk> the rest is rent and utilities and healthcare and loans
2022-01-24T19:52:35 < mawk> I never took a loan to buy drugs btw, I'm not that insane
2022-01-24T19:52:50 < ventYl> that's shitload of money
2022-01-24T19:53:15 < mawk> it depends on the month
2022-01-24T19:53:18 < mawk> usually it's just 200€
2022-01-24T19:53:22 < mawk> but last month was busy
2022-01-24T19:53:42 < mawk> and I am at -400€ on my account right now so I will have to pay it back first
2022-01-24T19:53:49 < mawk> so no funny things for me this month

2022-01-24T20:19:26 < BrainDamage> there's petrol stoves, but you need to be careful about food contamination
2022-01-24T20:19:55 < BrainDamage> unless you consider lead and benzene flavourful spices
2022-01-24T20:25:46 < PaulFertser> You're unlikely to find leaded petrol these days
2022-01-24T20:26:32 < fenugrec> except aviation 100LL still has lead
2022-01-24T20:26:49 < PaulFertser> btw, usually those portable petrol stoves should burn special purified petrol, not the one you get at an auto petrol station.
2022-01-24T20:44:56 <@englishman> and at racetracks

2022-01-24T20:45:51 <@englishman> plenty of lead to go round
2022-01-24T20:46:40 <@englishman> 100LL is getting banned from aerodromes left and right fen, and with replacement fuels finally becoming available i'd expect 100LL to be gone in 15-20 years
2022-01-24T20:47:13 < fenugrec> good old tetrasomething lead

2022-01-24T20:48:22 < fenugrec> for civil aviation, it'll have to wait for the engine mfg's to certify the alternatives, available or not
2022-01-24T20:48:38 <@englishman> apparently it is up to the FAA to approve
2022-01-24T20:48:58 < ventYl> is any significant amount of civil aviation still using piston engines?
2022-01-24T20:49:09 < ventYl> I assume that knock retardant are not relevant for jet engines
2022-01-24T20:49:15 <@englishman> they make a Supplemental Flight Certificate authorizing a certain airplane/engine combo to use G100UL
2022-01-24T20:49:27 <@englishman> *Supplemental Type Certificate
2022-01-24T20:49:40 <@englishman> yes the vast majority of GA is piston gas motors
2022-01-24T20:49:41 < fenugrec> ventYl, all single-engine cessna crap and similar size... some twin-engine pistons too. probably nothing bigger than 8-10 passenger
2022-01-24T20:49:47 < BrainDamage> dietary supplements in form of lead tablets
2022-01-24T20:50:01 <@englishman> jets are about 10x as expensive and much more complicated
2022-01-24T20:50:22 < BrainDamage> jets have issues about min output
2022-01-24T20:50:59 < BrainDamage> and when you scale them small, then in order to keep them efficient you need to have them spin at insane speeds
2022-01-24T20:51:10 < fenugrec> even the DC3's we still use in northern canadia are all (or nearly all) turbine conversions. I think we still have some CL-215 waterbombers with the awesome radials 
2022-01-24T20:51:11 < BrainDamage> for which the wear becomes high
2022-01-24T20:51:16 < ventYl> fenugrec: that should be doable, it will je just about several dozen of types

2022-01-24T23:08:25 < kakium69> opinions about samsung smart switch?
2022-01-24T23:09:44 < kakium69> I read the licence agreement and it forbids use of electronic or any other measure against data collection/telemetry the app does
2022-01-24T23:10:12 < kakium69> they really want that telemetry data
2022-01-24T23:11:43 < BrainDamage> a lot of licenses are unenforceable in tribunals, but you surely don't want to rile up samsung with enough money to keep you in tribunal not just for your lifetime, but all your descendants too
2022-01-24T23:13:07 < kakium69> nother fun thing is non-complete lists of data items collected

2022-01-24T23:15:36 < BrainDamage> the main issue is program settings, assdroid has lots of isolation and getting the permission to dump those is a pain

2022-01-24T23:16:19 < kakium69> isolation?
2022-01-24T23:17:30 < BrainDamage> program settings don't live in a shared space, like windows or linux, but in paths where only the os has access

2022-01-24T23:37:43 < bitmask> and i still have issues, and it might be because that area is permanently fux0red
2022-01-24T23:38:53 < BrainDamage> are you going to have other sections degenerate as well, or can you keep it in check with meds?
2022-01-24T23:39:38 < bitmask> i think it depends on if my body grows tolerant to the meds or not.  I think all these new biologics are a good thing though
2022-01-24T23:40:36 < bitmask> i think ive had crohns for years before getting diagnosed though so ive felt like crap even though taking all different kinds of meds, if surgery fixes how I feel and the meds keep everything else in check I might feel awesome for the first time in an extremely long time

2022-01-25T00:06:51 < catphish> BrainDamage: yeah, there seems to be a serial dick drawer!
2022-01-25T00:07:45 < Steffanx> We know its you.
2022-01-25T00:08:30 < catphish> most people who know me well would assume so
2022-01-25T00:08:34 < kakium69> probably first cave drawings were dicks
2022-01-25T00:08:51 < catphish> and yet, on this occasion, it was not, that's permanent marker!
2022-01-25T00:09:49 < kakium69> is that aluminum frame?
2022-01-25T00:09:53 < kakium69> or steel
2022-01-25T00:10:08 < kakium69> aluminium/aluminum
2022-01-25T00:10:21 < catphish> the main chassis is aluminium, but i think that rear frame is steel
2022-01-25T00:10:22 < Steffanx> Just tell the guy he should look at proper examples more because this one doesn't look great, catphish 
2022-01-25T00:10:38 < BrainDamage> you can probably polish it out
2022-01-25T00:11:59 < catphish> i expect so
2022-01-25T00:12:20 < catphish> though that particular metal strip sits under the fibreglass boot, so meh :)
2022-01-25T00:22:17 -!- Guest21 is now known as Laurenceb
2022-01-25T00:23:06  * Laurenceb has some very silly ideas
2022-01-25T00:23:08 < Laurenceb> https://uk.banggood.com/Flipsky-75100-FOC-75V-100A-Single-ESC-Based-on-VESC-For-Electric-Skateboard-Scooter-Ebike-Speed-Controller-Parts-reviews-p1909129.html
2022-01-25T00:23:51 < BrainDamage> are you going to use that for emdrive^Whyperloop?
2022-01-25T00:24:18 < Laurenceb> take this, swap the MOSFETs to IGBTs, swap drivers, add "body" diodes and swap electrolytics to film caps, then put in new enclosure
2022-01-25T00:24:21 < Laurenceb> yeah
2022-01-25T00:24:35 < BrainDamage> please film it
2022-01-25T00:24:41 < Laurenceb> looks like 200A at 800V should be possible
2022-01-25T00:24:48 < BrainDamage> possibly livestream
2022-01-25T00:24:52 < Laurenceb> lol
2022-01-25T00:25:18 < catphish> lol
2022-01-25T00:25:26 < Laurenceb> 160kW for <ukp200
2022-01-25T00:25:30 < BrainDamage> I'm sure the clearance between 75V and 800V is the same
2022-01-25T00:26:15 < BrainDamage> and the amount of energy that the snubber network has to substain
2022-01-25T00:26:31 < Laurenceb> add some resin...
2022-01-25T00:26:32 < catphish> it's not really that hard to build a 800V 100A inverter with an infineon module and an stm32, no idea how reading the back emf works though, i never did a fixed magnet one
2022-01-25T00:26:42 < Laurenceb> its worth a shot for the lulz
2022-01-25T00:27:23 < Laurenceb> the actual pro hyperloop inverter is tens of k in parts
2022-01-25T00:27:37 < Laurenceb> but this would be a lulzy haxor version
2022-01-25T00:27:38 < BrainDamage> the snubber network is sized so that when you shut off the power transistors, the energy accumulated in the mag/electric field in your circuit gets dumped in instead of a high z of an open transistor
2022-01-25T00:27:44 < BrainDamage> which would spike to kV
2022-01-25T00:28:10 < Laurenceb> hmm not really, when its properly set up that should go into the diodes
2022-01-25T00:28:16 < Laurenceb> and coil resistances
2022-01-25T00:28:27 < BrainDamage> nooope
2022-01-25T00:29:04 < BrainDamage> which shuts off earlier, a coil connected to an open circuit or a coil connected to a short?
2022-01-25T00:29:33 < BrainDamage> if you have the diodes continue circulating the current, you'll never be able to shut off the current
2022-01-25T00:29:38 < Laurenceb> if the transistors get hit by the full coil even the pro transistors will be toast, thats why we have diodes
2022-01-25T00:29:46 < BrainDamage> so the transistors will never be able to open
2022-01-25T00:30:01 < Laurenceb> theres plenty of resistance and losses, it decays in less than a millisecond
2022-01-25T00:30:30 < BrainDamage> so you're going to pwm at 100HZ?
2022-01-25T00:33:36 < Laurenceb> 25kHz
2022-01-25T00:33:54 < BrainDamage> then you'll have to change that millisecond into a microsecond
2022-01-25T00:34:51 < BrainDamage> and possibly even 0.1, if you want a decent pwm dyn range
2022-01-25T00:36:21 < BrainDamage> because otherwise, no matter how much you switch, the energy that you can partition by your transistor will be insignificant compared to the circulated one
2022-01-25T00:36:48 < BrainDamage> making it pretty much useless
2022-01-25T00:37:53 < BrainDamage> mind you, this is the speed for which you can make the current 0 in the partition branch, aka the modulating one
2022-01-25T00:38:21 < BrainDamage> and yes, inductance in the layout is non negibible and at your power it holds lethal amounts of energies
2022-01-25T00:38:28 < BrainDamage> and even capacitance

2022-01-25T01:46:40 < bitmask> i was wondering why imgui needed a descriptorpool but i guess i know why
2022-01-25T01:47:00 < bitmask> does it need its own renderpass or anything?

2022-01-25T01:47:43 < bitmask> ok
2022-01-25T01:47:55 < bitmask> you need to create that crazy pool with like 1000 of everything?
2022-01-25T01:48:00 < bitmask> or is that just an exxample
2022-01-25T01:48:47 < zyp> you need to create a pool, up to you whether you just make it 1000 of everything or actually put some thought into it
2022-01-25T01:48:51 < zyp> I went with the former
2022-01-25T01:48:55 < bitmask> i see

2022-01-25T09:50:37 < jpa-> http://jpa.kapsi.fi/stuff/pix/nrst_problem.png   white trace is with "reset_config srst_only", yellow trace is with "reset_config none"
2022-01-25T09:50:56 < jpa-> apparently when openocd does software reset, MCU pulls NRST pin low, because that's what it does
2022-01-25T09:51:18 < jpa-> and one cable has slightly more capacitance so NRST takes longer to rise, but openocd is impatient and retries, pulling NRST back low
2022-01-25T10:00:52 < jpa-> or maybe it is stlink that is impatient
2022-01-25T10:01:53 < jpa-> something is reissuing reset command over SWD every 1ms, but considering USB latency it probably has to come from stlink
2022-01-25T10:05:09 < jpa-> in any case, this probably explains my earlier thoughts that SWD is fiddly with long cables - turns out it is NRST that is fiddly

2022-01-25T10:35:35 < zyp> this is with internal reset pullup only?
2022-01-25T10:42:21 < PaulFertser> Interesting story.
2022-01-25T10:42:34 < PaulFertser> With reset_config none OpenOCD shouldn't be touching srst.
2022-01-25T10:48:24 < ventYl> i sometimes experience something, which seems to quite fit the description
2022-01-25T10:48:33 < ventYl> but I never dug deeply into the issue
2022-01-25T10:48:38 < ventYl> maybe my stlink is not even dead
2022-01-25T10:48:58 < jpa-> zyp: 100kohm external pullup
2022-01-25T10:49:33 < jpa-> PaulFertser: yeah, i think it is the stlink doing it - i'm not even sure what version firmware i have on there, probably a decade old
2022-01-25T10:49:49 < jpa-> or actually
2022-01-25T10:50:14 < jpa-> i think it is not stlink touching NRST either, it is normal for the MCU to pull it down on software reset request IIRC
2022-01-25T10:50:24 < jpa-> but it is probably stlink that keeps reissuing the reset request
2022-01-25T10:51:27 < jpa-> hmm, that NRST rise time is crazy slow

2022-01-25T10:52:51 < jpa-> even 100kohm + 100pF should give less than 0.1 ms rise time
2022-01-25T10:53:03 < jpa-> and that 15 cm cable definitely shouldn't be 100pF
2022-01-25T10:55:41 < jpa-> heh, STM32F3 discovery has 100nF capacitor in parallel with the reset button for debouncing
2022-01-25T10:56:13 < zyp> hah
2022-01-25T10:56:14 < jpa-> so because my NRST pin is connected to the stlink and because on discoverys the reset line does not have disconnect jumper, it is slowing down the rise time
2022-01-25T10:56:57 < jpa-> funny that the other cable must have somehow just little more resistance or inductance or something that it manages to come out of reset just in time
2022-01-25T11:08:29 < benishor> I kept looking at libopencm3 last few days and I find it very nice and clean
2022-01-25T11:08:53 < benishor> a great improvement over HAL
2022-01-25T11:09:26 < benishor> I guess it could use more "getting started" content like tutorials and such
2022-01-25T11:09:30 < benishor> and its adoption would increase
2022-01-25T11:13:12 < benishor> PaulFertser: finally found the usb problem I had yesterday cubemx related. a typical case of pebkac: while configuring the clock I had set the xtal to 16MHz instead of the 8MHz the board had
2022-01-25T11:17:29 < PaulFertser> benishor: oh, that's an unfortunate mistake to make when you're trying to use only USB and not UART.
2022-01-25T11:18:56 < zyp> jpa-, I've got a similarly fun problem here; I've got some imx7 SoMs that I've built an image for, and the image only boots on one of the three I've tested so far
2022-01-25T11:19:04 < jpa-> benishor: libopencm3 adoption is hurt by license - while something like chibios one can always pay for, with libopencm3 you are stuck with lgpl
2022-01-25T11:19:46 < zyp> it works fine on the one I had for desktop test, but fails on both the ones mounted in actual product that I've tested
2022-01-25T11:20:04 < zyp> swapping my module into either of the products works, so it's not a host board issue
2022-01-25T11:20:25 < zyp> and all three of them boots a different image perfectly fine
2022-01-25T11:20:39 < benishor> jpa-: then why doesn't the license change?
2022-01-25T11:20:54 < benishor> am I right to assume the author is from ##stm32?
2022-01-25T11:21:21 < jpa-> there are libopencm3 contributors here, but it does not have a single author
2022-01-25T11:21:23 < zyp> benishor, as an open source project, there's a bunch of authors
2022-01-25T11:21:36 < jpa-> and some of the old time authors are against license change
2022-01-25T11:21:54 < zyp> and they all have a say of the license of their contributed changes
2022-01-25T11:21:58 < benishor> I would love to switch to libopencm3 but it would take me a bit of time to write all the drivers for the stm32f746 discovery peripherals 
2022-01-25T11:22:14 < jpa-> benishor: have you looked into chibios?
2022-01-25T11:22:20 < benishor> jpa-: not at all
2022-01-25T11:22:33 < jpa-> even if you don't use the RTOS part, the HAL part is pretty nice - and on F7 you have resources to spare even for RTOS
2022-01-25T11:24:54 < benishor> I just took a look at the documentation, a very skimmed one
2022-01-25T11:25:33 < benishor> what would be the arguments for chibios against libopencm3 aside the license?
2022-01-25T11:26:36 < jpa-> better hardware support
2022-01-25T11:29:48 < benishor> so far, just by looking at example code, I tend to like libopencm3's style and approach better
2022-01-25T11:30:30 < benishor> otoh documentation seems to be far better on chibios' side
2022-01-25T11:31:57 < karlp> there's no chance of libopencm3 getting alicense change.  some of the original authors wanted it to be gpl only, the lgpl was as far as they could be moved.
2022-01-25T11:32:11 < benishor> also a minus for chibios is the missing support in platformIO
2022-01-25T11:32:28 < karlp> platform io's "support" for something can often be very slim...
2022-01-25T11:32:33 < karlp> I wouldn't read too muhc into that..
2022-01-25T11:32:51 < benishor> so what are you guys using?
2022-01-25T11:33:00 < benishor> consider it a poll
2022-01-25T11:33:35 < karlp> I have a variety of things with libopencm3, but am currently spending more time with laks.
2022-01-25T11:33:42 < karlp> I've never been happy with st hal.
2022-01-25T11:34:26 < karlp> I tried stm32-rs/stm32xx-hal and was pretty unhappy too,
2022-01-25T11:34:55 < benishor> thanks karlp
2022-01-25T11:34:58 < benishor> any other takers?
2022-01-25T11:35:24 < karlp> you'll hear hal, hal, hal, custom private, custom private, nuttx, chibios....

2022-01-25T12:51:03 < zyp> jpa-, I thought the best thing was how everything is 0-based instead of 1-based
2022-01-25T12:51:05 < karlp> or these, but longer: https://www.aliexpress.com/item/1005001736666879.html

2022-01-25T13:25:56  * catphish hates interrupts
2022-01-25T13:28:22 < catphish> i want a level high on a pin to wake my RP2040, simples, but if i set a level high interrupt, the interrupt routine is *always* running :(
2022-01-25T13:29:06 < ventYl> isn't there edge/level switch somewhere?
2022-01-25T13:29:16 < ventYl> that's a subtle difference
2022-01-25T13:29:33 < catphish> sure there is
2022-01-25T13:30:05 < catphish> but if i set an edge interrupt, there's no guarantee the edge won't happen between configuring the interrupt, and calling WFI
2022-01-25T13:31:26 < catphish> in which case, the interrupt fires, then the device goes to sleep, and it's not called again, the user thinks they're sending a high level to wake the device, but it's not awake
2022-01-25T13:31:47 < PaulFertser> catphish: aren't you supposed to somehow ACK the external IRQ source and then the pin goes down and you stop getting the interrupt?
2022-01-25T13:31:59 < jpa-> catphish: disable interrupts, enable level IRQ, call WFI, disable level IRQ, enable interrupts
2022-01-25T13:32:47 < jpa-> or just disable the level IRQ in the level IRQ handler
2022-01-25T13:34:03 < PaulFertser> catphish: or is level high meant as "keep running" line? Then why do not you simply disable the interrupt on wakeup and enable prior to going to sleep?
2022-01-25T13:34:20 < catphish> PaulFertser: yes, this is exactly that, it's a "don't sleep" line
2022-01-25T13:35:02 < catphish> if i enable a LEVEL interrupt prior to going to sleep, and the level is already high, i immediately enter an infinite interrupt loop
2022-01-25T13:35:22 < PaulFertser> catphish: an ISR preempts itself?
2022-01-25T13:35:40 < catphish> no, it just runs continuously
2022-01-25T13:35:55 < catphish> as soon as it returns, it's called again
2022-01-25T13:35:56 < PaulFertser> catphish: but you disable the interrupt on entry.
2022-01-25T13:36:37 < catphish> but.... :( if i disable the interrupt, and then sleep, i'll NEVER wake up
2022-01-25T13:36:57 < PaulFertser> catphish: you do not enter sleep from the ISR.

2022-01-25T13:37:17 < jpa-> catphish: disable the interrupt in the interrupt handler
2022-01-25T13:37:58 < catphish> as above, if i disable the interrupt in the handler, then the enable interrupt -> sleep will result in sleeping forever!
2022-01-25T13:38:01 < jpa-> but yeah, it is easier if you just global disable interrupts before calling WFI
2022-01-25T13:38:24 < jpa-> then you can just check the level before calling WFI, with no risk of interrupt handlers getting in between
2022-01-25T13:38:59 < catphish> i'm still not seeing it :(
2022-01-25T13:40:31 < jpa-> you can also set the pin to generate event instead of interrupt, and use WFE instead
2022-01-25T13:40:31 < catphish> there's surely ALWAYS going to be a period between enabling the interrupt, and going to sleep
2022-01-25T13:40:42 < catphish> and if the interrupt happens during that period, i have a problem
2022-01-25T13:42:08 < jpa->  __disable_irq();  my_enable_level_irq();  __WFI();  my_disable_level_irq();  __enable_irq();
2022-01-25T13:42:32 < jpa-> WFI will wake on interrupt flags even if interrupt handlers are disabled by cpsid
2022-01-25T13:43:03 < catphish> oh, if the MCU wakes on interrupts even when interrupts are disabled, that completely solves my problem
2022-01-25T13:43:23 < catphish> nb. not STM32, i'll try it!
2022-01-25T13:43:32 < jpa-> that applies only to cpsid/primask
2022-01-25T13:43:37 < jpa-> not to the per-interrupt enable bits
2022-01-25T13:44:51 < jpa-> if you want to wake only on that pin and no other interrupts, you can also set the pin to generate event instead and use WFE
2022-01-25T13:45:31 < catphish> that might be sane
2022-01-25T13:51:19 < catphish> "cpsid i" works exactly as hoped, thank you!

2022-01-25T14:32:22 < benishor> continuing the bluepill usb saga: I'm pulling my hair out trying to do a simple dfu example
2022-01-25T14:32:47 < benishor> I got the simplest bootloader flashed, writing to 0x08008000
2022-01-25T14:32:58 < benishor> I get dfu-util to recognise it when in dfu mode
2022-01-25T14:33:34 < PaulFertser> benishor: btw, my binary includes DFU bootloader and then it's reflashable with dfu-util.
2022-01-25T14:33:40 < benishor> I wrote a simple blinky to which I changed FLASH_START to 0x08008000 and linker flash origin
2022-01-25T14:33:50 < benishor> I can upload it just fine, but it just won't start
2022-01-25T14:34:02 < benishor> PaulFertser: what address?

2022-01-25T15:28:24 < ventYl> what is so special about it?
2022-01-25T15:33:32 < benishor> for example, taking PaulFertser's above mentioned bootloader as an example, opencod can only connect when the board is in dfu mode

2022-01-25T15:34:16 < PaulFertser> benishor: your app must leave SWD enabled
2022-01-25T15:34:24 < zyp> a custom bootloader is just another application
2022-01-25T15:34:49 < zyp> so you debug it like any other application
2022-01-25T15:35:07 < ventYl> in my legacy AVR shit, a bootloader is just a special case of an application 
2022-01-25T15:35:15 < ventYl> which chain-loads "the application"

2022-01-25T15:35:42 < benishor> I meant debugging the "loaded" application, not the bootloader itsel

2022-01-25T16:03:59 < josuah> kakium69: maybe google only wants you to be a gambler, not that it thinks you are one already
2022-01-25T16:04:46 < kakium69> google thinks I have stupid money

2022-01-25T16:05:10 < josuah> ;)
2022-01-25T16:05:49 < catphish> yay all functionality of my first new board works as it should idle power consumption is 2.7mA @ 12V not great, but i'm happy enough, no idea what's still drawing that current!
2022-01-25T16:08:46 < josuah> catphish: how do one measure power consuption (mA)? An ampermeter between Vcc and Vss?
2022-01-25T16:09:27 < catphish> i have a multimeter between my 12v input and my power supply
2022-01-25T16:09:48 < ventYl> is it accurate?
2022-01-25T16:10:02 < josuah> thanks, let's get a peek then...
2022-01-25T16:10:04 < catphish> my power supply actually reads 0.000A but i trust the 2.7mA reported by my multimeter more, but honestly i don't know if it' accurate
2022-01-25T16:10:37 < josuah> catphish: so it would be possible to check for each peripheral then? in case one of them drags all the power
2022-01-25T16:10:52 < ventYl> catphish: PSU back at automotive job shown 100mA after it warmed up all the time
2022-01-25T16:11:35 < ventYl> rp2040 has one nasty feature. it defaults to all peripherals and clocks being turned on by default
2022-01-25T16:11:41 < catphish> https://i.imgur.com/QYJc5yP.jpg
2022-01-25T16:11:46 < ventYl> are you sure you turned off everything you don't use?
2022-01-25T16:12:02 < catphish> ventYl: i've turned off all the *clocks* i'm not using, but not necessarily the peripherals
2022-01-25T16:13:00 < catphish> also, interestingly, the "dormant" mode provided by the SDK pulls way more power than my own attempt to manually stop all the clocks and WFI
2022-01-25T16:13:00 < ventYl> and ofc the external flash may have it's part in consumption as well
2022-01-25T16:13:14 < catphish> yeah, i think the external flash will definitely contribute, that will always be on
2022-01-25T16:13:59 < catphish> i should probably test the Pi in isolation to rule out anything else on my board, but frankly, everything else on my board is shut down with a simple shutdown pin
2022-01-25T16:14:45 < ventYl> typical modern interconnected automotive HW turns MCUs down completely, so they can afford to be connected to KL30
2022-01-25T16:14:49 < ventYl> instead of KL15
2022-01-25T16:15:52 < ventYl> there you can go down to like several uA while standby
2022-01-25T16:16:19 < catphish> well if i was using an stm32 i'd be confident i could achieve uA standby
2022-01-25T16:16:46 < kakium69> catphish: did you remember can tranceiver standby line in this revision?
2022-01-25T16:17:04 < catphish> kakium69: yes :)
2022-01-25T16:17:23 < catphish> that bought me about 3mA!
2022-01-25T16:19:28 < catphish> i suspect i still have an oscillator running, i'll keep poking it
2022-01-25T16:22:05 < catphish> yep, if i kill the crystal oscillator, it drops from 2.7mA to 0.5mA! just need to write the code to actually survive that 
2022-01-25T16:23:34 < Sadale> wow. Isn't that raspi pico?
2022-01-25T16:23:51 < ventYl> it is
2022-01-25T16:24:40 < Sadale> overpriced :P
2022-01-25T16:25:08 < Sadale> seriously tho it isn't. It's not bad for its price. But it's a bit bulky IMO. Still manageable.
2022-01-25T16:25:19 < catphish> bulky?
2022-01-25T16:25:35 < ventYl> one has to understand that primary use for raspi products is not in serious industry
2022-01-25T16:26:02 < catphish> the RP2040 is a very cool toy, but perhaps still a toy for now
2022-01-25T16:26:09 < ventYl> right
2022-01-25T16:26:13 < catphish> and i'm okay with that, it keeps them in stock
2022-01-25T16:28:03 < josuah> what about the GD32V? the risc-v from GigaDevice?
2022-01-25T16:30:20 < josuah> maybe it is more a matter of being GigaDevice than being risc-v
2022-01-25T16:31:12 < Sadale> What makes RP2040 not quite for serious use?
2022-01-25T16:31:19 < Sadale> like what makes it not quite ready for that?
2022-01-25T16:32:05 < ventYl> you can use it seriosly, but their primary target is not industrial use
2022-01-25T16:32:10 < josuah> the GD32 look like copycats of the STM32
2022-01-25T16:32:26 < Sadale> There's also CH32
2022-01-25T16:32:43 < Sadale> They all look like copycats. I'm not sure on how compatible they actually are.
2022-01-25T16:33:30 < catphish> Sadale: i guess it's more about marketing (and perhaps certification) than actual function
2022-01-25T16:33:57 < josuah> https://hackaday.com/2020/10/22/stm32-clones-the-good-the-bad-and-the-ugly/
2022-01-25T16:34:10 < josuah> Sadale: according on hackaday, it depends on which one
2022-01-25T16:34:21 < josuah> chinese copycat industry is impressive
2022-01-25T16:34:32 < Sadale> The certs - maybe. As for the actual function tho, actually, I find the specs of RP2040 apparently to be up to par for its price.
2022-01-25T16:34:38 < josuah> it is a bit harder than doing fake nike shoes
2022-01-25T16:36:41 < ventYl> Sadale: for actuall matter. RP2040 is designed in a way, that it has most of stuff turned on by default, so shortest code path will mostly work with every peripheral without complicated setup
2022-01-25T16:37:11 < ventYl> unlike let's say STM32 or NRF, where shortest path will lead to rather small consumption but you have to configure every peripheral specifically and activate clocks
2022-01-25T16:37:13 < Sadale> Interesting. So, could you turn them off?
2022-01-25T16:37:21 < ventYl> RP2040 definitely is not a lowest power device you can get
2022-01-25T16:37:32 < Sadale> I see. The power consumption.
2022-01-25T16:37:35 < catphish> success, 580uA sleep :)
2022-01-25T16:37:50 < kakium69> nice
2022-01-25T16:37:52 < catphish> that's the value i was expecting
2022-01-25T16:37:54 < ventYl> you could, but the granularity is not as good as with STM32, where you have way greater control over what runs and what not
2022-01-25T16:38:03 < ventYl> IIRC RP2040 only has one clock domain for peripherals
2022-01-25T16:38:07 < ventYl> or maybe even for everything
2022-01-25T16:38:17 < Sadale> It does offer plenty of RAM tho. And it supports mapping to external flash, which isn't supported by lower-end MCUs
2022-01-25T16:38:34 < Sadale> oh. Sucks to have just one clock domain.
2022-01-25T16:38:35 < ventYl> external flash is a must have as it doesn't have any internal flash
2022-01-25T16:39:01 < catphish> it has a few clocks, internal and external oscillator, and 2 PLLs (one dedicated to USB), but only a single clock gate for most peripherals
2022-01-25T16:39:20 < catphish> (shared between most peripherals)
2022-01-25T16:39:47 < catphish> it's 100% not a low power device, in fact it's catastrophically inefficient compared to an stm32
2022-01-25T16:40:31 < Sadale> I see. Now that it got me into thinking, what's the advantage of having multiple clock domains?
2022-01-25T16:40:43 < Sadale> Is that for power saving?
2022-01-25T16:40:51 < catphish> sometimes you want to run things at different speeds, usually for power saving
2022-01-25T16:42:33 < catphish> in my case i can now leave my 2 baords connected to my permanent live in my car, they will draw 1mA combined, but that's not going to drain a car battery very fast
2022-01-25T16:43:27 < catphish> i did consider having them recharge the battery autoatically if it gets low, but decided that was too dangerous
2022-01-25T16:45:58 < catphish> even a tiny 7Ah battery should now last me almost a year
2022-01-25T16:47:06 < catphish> fun fact, when waking up from "all oscillators off" deep sleep, then rp2040 automatically re-enables al clocks, so you have to go back to tidy up every time :)

2022-01-25T16:52:10 < Mangy_Dog> why the heck is this chip shortage still going on
2022-01-25T16:53:28 < BrainDamage> one fab schedules operate on 6-12 months slots, two people started speculating on it
2022-01-25T16:53:51 < Mangy_Dog> :/
2022-01-25T16:54:37 < Steffanx> Even lcsc has thousands of stm32s  smaller ones and bigger ones 
2022-01-25T16:54:54 < PaulFertser> Mangy_Dog: why do you need a load, a new project or some of your old ones getting hot sale?
2022-01-25T16:55:16 < Mangy_Dog> well i have 12 tricorders to build :/
2022-01-25T16:55:23 < Mangy_Dog> thats going to use up pretty much all my stock
2022-01-25T16:55:23 < PaulFertser> Wow
2022-01-25T16:55:33 < Mangy_Dog> and i need some more for a few other projects
2022-01-25T16:55:34 < PaulFertser> Congrats with success!
2022-01-25T16:55:37 < Mangy_Dog> thanks
2022-01-25T16:55:48 < PaulFertser> (I assume that's a success for your model of operation)
2022-01-25T16:56:18 < Mangy_Dog> well it'll give me a little bumper i sorly need
2022-01-25T16:56:26 < PaulFertser> Guess it's time for you to consider moving away from stm32f1 for any newish or old resurrected project.
2022-01-25T16:56:43 < BrainDamage> how much are you going to charge each?
2022-01-25T16:57:19 < BrainDamage> catphish: a small solar panel and you won't even need to bother with charge at all

2022-01-25T17:02:22 < karlp> a "tiny" 7Ah battery :)

2022-01-25T17:02:56 < ventYl> 50ccm scooters usually have such
2022-01-25T17:03:05 < karlp> I know :)
2022-01-25T17:05:56 < fenugrec> heh, a minimal ncurses implementation for mcus: https://github.com/ChrisMicro/mcurses 
2022-01-25T17:06:59 < catphish> i'm thinking of using an alarm system backup battery
2022-01-25T17:07:36 < catphish> https://www.yuasa.co.uk/batteries/industrial/np7-12.html
2022-01-25T17:09:41 < ventYl> as you already have BMS, wouldn't be some li-ion battery be a better solution?
2022-01-25T17:09:50 < catphish> no
2022-01-25T17:10:33 < ventYl> I fucking hate visual C++ compiler
2022-01-25T17:10:36 < catphish> technically, yes a lithium battery would be better, but it would require its own BMS and charging setup
2022-01-25T17:10:47 < catphish> and it's just not worth the hassle for this application
2022-01-25T17:11:12 < ventYl> catphish: hm, wouldn't be a single-cell and off-the-shelf BMS way to go?
2022-01-25T17:11:28 < catphish> ventYl: well, one can buy lithium VRLA replacements
2022-01-25T17:11:39 < catphish> so perhaps one of those, but then the difference it moot
2022-01-25T17:12:27 < catphish> the issue is that it needs to provide 12v, and be charged from 12v
2022-01-25T17:13:02 < catphish> (directly or otherwise)
2022-01-25T17:13:16 < ventYl> yeah
2022-01-25T17:14:03 < catphish> and while that's possible, it's likely not worth the effort of designing, or cost of buying
2022-01-25T17:14:23 < BrainDamage> why don't you slap a 12V solar panel to it, you don't even need a mppt tracker
2022-01-25T17:14:26 < ventYl> how much that backup battery costs?
2022-01-25T17:14:28 < BrainDamage> just let it float charge
2022-01-25T17:14:38 < catphish> ventYl: about 20GBP
2022-01-25T17:14:53 < ventYl> ok, that's somewhere around motorcycle 9Ah battery would cost
2022-01-25T17:15:10 < catphish> ventYl: yeah, motorcycle battery also an option
2022-01-25T17:16:10 < catphish> BrainDamage: the battery should last months powering nothing but my 2 boards, and a radio's idle circuit
2022-01-25T17:16:20 < catphish> no need to worry about charge really
2022-01-25T17:16:45 < catphish> if the car's stored long term, it'll be indoors, solor panel would be pretty useless
2022-01-25T17:17:12 < ventYl> you could keep some light turned on in order to charge stuff :>
2022-01-25T17:17:17 < catphish> nothing stopping me plugging a solar panel into the 12v socket in the car :)
2022-01-25T17:17:50 < ventYl> if you can get flexible solar cells, then why not creating something like solar-powered sunroof?
2022-01-25T17:17:54 < catphish> but if it's stored, i'll probably connect an external float charger anyway
2022-01-25T17:18:10 < ventYl> such stuff is advertised as super-modern, but one could get that as an option some 30+ years ago
2022-01-25T17:18:13 < catphish> i could, but i won't effort/reward ratio at work here
2022-01-25T17:44:31 < Steffanx> Mangy_Dog:  buy some discovery l053s and desolder the f103cb 
2022-01-25T17:45:16 < Steffanx> The discovery comes with 3 stm32s. L053, L152 and F103
2022-01-25T17:45:46 < fenugrec> ^ f103 does stlink, but why l152 ?
2022-01-25T17:46:59 < Mangy_Dog> i ordered 90 quids worth of stm32f103c8s off ali >.<
2022-01-25T17:47:04 < Mangy_Dog> fingers crossed theyre not fake
2022-01-25T17:47:26 < Mangy_Dog> well 20 C8s and 10 CBs
2022-01-25T17:47:29 < Mangy_Dog> ill test them all
2022-01-25T17:47:43 < PaulFertser> Mangy_Dog: what if they're fake? Have you checked the list of "features" with more detailed explanations of what makes fakes different?
2022-01-25T17:48:41 < PaulFertser> Probably the fakes are also OK for your purposes?
2022-01-25T17:50:53 < Steffanx> I'm not sure yet, fenugrec  
2022-01-25T17:53:17 < Mangy_Dog> well
2022-01-25T17:53:24 < Mangy_Dog> depends on HOW fake they are
2022-01-25T17:57:35 < BrainDamage> you could probably jury rig a stand to keep the ic in place on a populated board that lacks the stm32, and then test them
2022-01-25T17:58:02 < BrainDamage> like using pogo pins as spring loaded holders that push the chip on the board
2022-01-25T17:58:13 < BrainDamage> then you can directly test by flashing your firmware
2022-01-25T18:01:31 < Mangy_Dog> i have a clamshell qfp socket i can test them in
2022-01-25T18:01:39 < Mangy_Dog> already setup to connect to stlink utility
2022-01-25T18:01:54 < BrainDamage> then it's 'just' a matter of testing
2022-01-25T18:02:12 < BrainDamage> and you can offload the cost of the fakes to your customers
2022-01-25T18:21:34 < PaulFertser> Mangy_Dog: but what kind of testing are you going to do in that rig?
2022-01-25T18:21:58 < Mangy_Dog> At the moment just loading it up in stlink util and checking its ID and flash size

2022-01-25T22:03:41 < kakium69> wifi direct is nice
2022-01-25T22:04:14 < kakium69> I used to copy shits with adb.exe like a fool
2022-01-25T22:04:55 < kakium69> limited with usb hs speeds ofc
2022-01-25T22:07:39 < Steffanx> For me smart switch has done the job so far
2022-01-25T22:07:55 < Steffanx> Don't care about most of the app settings 
2022-01-25T22:10:16 < PaulFertser> kakium69: how do you actually use wifi direct, what does the process look like from an end user point of view?
2022-01-25T22:11:16 < kakium69> press share button
2022-01-25T22:11:23 < kakium69> select wifi direct
2022-01-25T22:11:31 < kakium69> select device
2022-01-25T22:11:42 < PaulFertser> Share buton where? On Android in some file explorer tool?
2022-01-25T22:11:53 < kakium69> yes
2022-01-25T22:13:04 < PaulFertser> And then when you select wifi direct what do you need to do to the other devices so that you can select them?
2022-01-25T22:13:34 < BrainDamage> there's android beam where you negotiate the wifi direct settings over nfc then use that as high throughtput channel
2022-01-25T22:13:57 < BrainDamage> which is basically, select file, put phones against eachother and accept transfer
2022-01-25T22:15:30 < BrainDamage> I've managed to use wifi direct on phone and wpa_supplicant on linux and it's ... messy
2022-01-25T22:16:09 < BrainDamage> but once I've setup, I've got a private link between my laptop and pc that works regardless of infra
2022-01-25T22:16:17 < BrainDamage> which is super nice
2022-01-25T22:16:40 < BrainDamage> and standard AP mode still works on the side
2022-01-25T22:16:49 < BrainDamage> so it's not like tethering/AP mode
2022-01-25T22:17:00 < kakium69> PaulFertser: first you pair them before starting ofc
2022-01-25T22:17:14 < kakium69> enable wifi direct in both of them
2022-01-25T22:17:40 < kakium69> then select device from one device and accept from another device
2022-01-25T22:19:28 < PaulFertser> BrainDamage: afaik P2P-client / P2P-GO are very similar to normal STA / AP modes, so I'm not surprised what you described is an allowed interface combination. One can check "iw list" for details.
2022-01-25T22:19:55 < BrainDamage> correct
2022-01-25T22:20:10 < PaulFertser> BrainDamage: you you could probably just run hostapd normally on your laptop with about the same outcome.
2022-01-25T22:20:22 < BrainDamage> but what you want to do that isn't described around, is to use a feature to make a virtual p2p interface
2022-01-25T22:20:51 < BrainDamage> then you can use that to connect around
2022-01-25T22:20:59 < PaulFertser> Didn't you use "iw phy .. interface add" command as you would with any other vif?
2022-01-25T22:21:24 < BrainDamage> I directly used wpa_supplicant's feature to create it
2022-01-25T22:21:38 < PaulFertser> Ah, cool.
2022-01-25T22:21:45 < BrainDamage> driver_param=use_multi_chan_concurrent=1 use_p2p_group_interface=1
2022-01-25T22:22:03 < PaulFertser> multi_chan? What device is that, intel?
2022-01-25T22:22:09 < BrainDamage> yes
2022-01-25T22:22:36 < PaulFertser> I see. All the others are restricted to using the same channel for all vifs.
2022-01-25T22:24:56 < BrainDamage> what I really wanted is setup wifi mesh, but that's an entirely different can of worms
2022-01-25T22:29:08 < benishor> https://ciechanow.ski/gps/
2022-01-25T22:30:44 < PaulFertser> BrainDamage: I thought 802.11s works out of the box without any effort?
2022-01-25T22:36:57 < BrainDamage> PaulFertser: I wanted a simultaneous mesh and AP/STA mode since not all my devices support it
2022-01-25T22:38:51 < PaulFertser> BrainDamage:  * #{ IBSS } <= 1, #{ managed, AP, mesh point } <= 8 <-- on mt7612
2022-01-25T22:39:30 < PaulFertser>  * #{ managed } <= 2048, #{ AP, mesh point } <= 8, #{ P2P-client, P2P-GO } <= 1, #{ IBSS } <= 1 <-- on old ath9k
2022-01-25T22:41:21 < PaulFertser> So it looks like you can have that with 802.11s as well as with BATMAN or oslrd over IBSS.
2022-01-25T22:42:44 < karlp> cute, got openocd stuck in an infinte loop somehow.
2022-01-25T22:44:24 < karlp> I suspect it's a bug in stlink firmware or something I guess, it just happend when I typed "load"
2022-01-25T22:44:31 < karlp> can't even ctrl-c the process.
2022-01-25T22:46:31 < karlp> PaulFertser: is https://paste.jvnv.net/view/lZXAb (gdb bt) and https://paste.jvnv.net/view/El2B6 (strace) interesting at all?

2022-01-25T22:48:01 < Laurenceb> https://pastebin.com/bVX1Ya1q
2022-01-25T22:48:53 < Laurenceb> looks ok?
2022-01-25T22:49:38 < karlp> who knows?
2022-01-25T22:49:49 < Laurenceb> yeah I dont want a reboot loop
2022-01-25T22:49:58 < Laurenceb> it seemed to work ok...
2022-01-25T22:50:32 < BrainDamage> what bootloader are you using?
2022-01-25T22:50:52 < BrainDamage> the broadcom boots the fat32, but then you should chainload your own bootloader
2022-01-25T22:51:12 < BrainDamage> for one, I don't see any config file about it
2022-01-25T22:51:23 < BrainDamage> ah nvm, missed it
2022-01-25T22:51:29 < BrainDamage> you have uboot
2022-01-25T22:51:37 < BrainDamage> cmdline and config .txt
2022-01-25T22:51:41 < Laurenceb> yeah
2022-01-25T22:52:10 < Laurenceb> hmm stock pi doesnt have the boot flag set...
2022-01-25T22:52:15 < Laurenceb> dunno if that could brick it?
2022-01-25T22:52:35 < Laurenceb> Device         Boot  Start      End  Sectors   Size Id Type
2022-01-25T22:52:47 < Laurenceb> Device         Boot  Start      End  Sectors   Size Id Type
2022-01-25T22:53:09 < BrainDamage> that's because it's not using efi
2022-01-25T22:53:18 < Laurenceb> ok
2022-01-25T22:53:23 < BrainDamage> the boot flag is for esp, while broadcom's bootloader is its own thing
2022-01-25T22:53:45 < BrainDamage> i think there's also an efi mode, but I am not sure how to set/use it
2022-01-25T22:53:47 < Laurenceb> hmm maybe I should try to reboot
2022-01-25T22:54:15 < BrainDamage> also, get a qemu static installation and combine with binfmt
2022-01-25T22:54:23 < BrainDamage> then you can just chroot into the sd
2022-01-25T22:54:28 < Laurenceb> but the pi is in Portugal and I'm in UK...
2022-01-25T22:54:54 < BrainDamage> the don't fuck with it outside business hours
2022-01-25T22:55:16 < PaulFertser> karlp: can't tell but it's odd you can't C-c. I'm long since being in the loop and if I can't reproduce it I don't think I can debug that.
2022-01-25T22:57:13 < Laurenceb> plan is that there will be a database on raw partition
2022-01-25T22:57:55 < karlp> PaulFertser:yeah, I can't even repro it myself, will ignore it unti it happens a lot more :)
2022-01-25T22:58:02 < karlp> just not used to not being able to ctrl-c it :)
2022-01-25T22:58:11 < Laurenceb>  /etc/fstab is only for mounted stuff right?
2022-01-25T22:58:49 < karlp> well, there it is again..
2022-01-25T22:59:04 < karlp> I wonder if this will keep happening until I power cycle the stlink....
2022-01-25T22:59:22 < PaulFertser> Laurenceb: people often specify swaps in /etc/fstab too.
2022-01-25T23:00:04 < Laurenceb> ok
2022-01-25T23:00:34 < BrainDamage> here's a less retarded idea: setup a partition, allocate a file as big as a partition, save the indexes, and then directly write in those
2022-01-25T23:00:47 < BrainDamage> then at least you can use regular file tools to interact with it
2022-01-25T23:01:08 < karlp> whee, brand new openocd same behaviour :)
2022-01-25T23:01:18 < BrainDamage> while still keeping your raw access
2022-01-25T23:01:45 < BrainDamage> swapfiles in fact work like this, one huge chunk of continously allocated memory
2022-01-25T23:01:51 < BrainDamage> and then you just pass the offsets
2022-01-25T23:02:14 < BrainDamage> in fact, you could even skip the partition and just make a swapfile
2022-01-25T23:02:43 < PaulFertser> karlp: might worth filing a ticket then.
2022-01-25T23:03:15 < Laurenceb> BrainDamage: my eMMC has 512byte sectors, but ext4 is 4kB
2022-01-25T23:03:31 < Laurenceb> giving x8 write amplification
2022-01-25T23:04:35 < BrainDamage> now, considering even the cheapest shit sd from 15 years ago has wear leveling, how much are you going to write on it?
2022-01-25T23:06:26 < Laurenceb> about 1k write cycles per bit
2022-01-25T23:06:50 < BrainDamage> because a 64GB SD with a write amplification factor of 50, and 10GB/day of data, and 10k write cycles would exaust itself in ~3.5 years
2022-01-25T23:07:11 < BrainDamage> and 10 GB/day is a lot
2022-01-25T23:07:13 < Laurenceb> yeah I need >20 year design life
2022-01-25T23:07:30 < Laurenceb> and there is that level of writing going on
2022-01-25T23:07:55 < BrainDamage> then don't write to a mmc ..., especially one your os is on
2022-01-25T23:08:04 < Laurenceb> woah spotted something potentially bad: fatlabel is boot on the stock rpi
2022-01-25T23:08:45 < Laurenceb> that might be used by broadcom
2022-01-25T23:08:59 < fenugrec> benishor, that page starts out pretty basic, but the stuff at the end is pretty on point
2022-01-25T23:09:24 < fenugrec> clearly spent many many hours making that

2022-01-25T23:13:17 < BrainDamage> Laurenceb: use set -e
2022-01-25T23:13:23 < BrainDamage> assuming that's bash
2022-01-25T23:13:26 < Laurenceb> ok
2022-01-25T23:13:38 < BrainDamage> that'll make the script to halt at first error
2022-01-25T23:13:55 < BrainDamage> otherwise, if one command fails, it'll still reach the point where it'll remove the backup
2022-01-25T23:14:06 < Laurenceb> ah good point thanks
2022-01-25T23:14:46 < BrainDamage> also, since you're literally prefixing every command with sudo, you should just sudo the whole script

2022-01-26T01:56:54 < karlp> well, I'm going to pretend I never had that problem for a bit, but wow, that was weird.

2022-01-26T02:11:33 < karlp> anyway, next wonky...   Connect meter on mA terminal, power on.  supply  says ~1mA, meter says ~300uA, bluetooth works, scans, all the good shit.
2022-01-26T02:12:30 < karlp> connect meter on uA terminal..... power on, supply syas ~2mA, meter says 1100uA, bluetooth doesn't work at all, 
2022-01-26T02:13:30 < catphish> try eating it
2022-01-26T02:13:43 < karlp> meter specs say burden voltage is 0.15mV/uA on both 500uA and 5000uA range, but doesn't really make any comment on the two different dial settings.
2022-01-26T02:14:01 < karlp> I mean, ok, I'll just use the mA dial setting, but what's the uA one for then?
2022-01-26T02:14:47 < catphish> my guess: large shunt resistor is limiting peak current
2022-01-26T02:15:01 < karlp> I suspect a peak too.
2022-01-26T02:17:18 < karlp> ok, crest mode on the meter on mA says it's hitting ~11-12mA, so I guess it'ðs blowing out something on the uA range,
2022-01-26T02:17:42 < karlp> but still,  I would have thought it would just be "over" at the start and then ok.
2022-01-26T02:17:45 < catphish> ya
2022-01-26T02:17:58 < karlp> not just "doesn't work at all on this mode"
2022-01-26T02:18:08 < catphish> my money's on a large shunt resistor
2022-01-26T02:18:19 < catphish> causing a voltage drop at peak current draw
2022-01-26T02:18:26 < karlp> though I guess the stm32 has probably not properly started up due to the limited current, so it's not running because it never got that voltage.
2022-01-26T02:18:32 < catphish> if it was a fuse, the result would be more dramatic
2022-01-26T02:18:42 < karlp> I don't have a scope here to look at the voltage,
2022-01-26T02:18:56 < karlp> the supply is in CV mode, but it probably can't react fast enough to give it more power.
2022-01-26T02:19:14 < catphish> it wouldn't help if it could
2022-01-26T02:19:22 < catphish> the voltage drop is after the power supply
2022-01-26T02:19:43 < karlp> I tried 0v3rcl0l1king it by putting the voltage up to 2V, but no good.
2022-01-26T02:20:05 < catphish> yeah that could have worked
2022-01-26T02:20:17 < fenugrec> just hooke up your meter on uA range with the probes shorted, power on, unshort the leads ?
2022-01-26T02:20:34 < fenugrec> or are you trying to puzzle the exact root cause with no scope
2022-01-26T02:20:34 < catphish> ^ this is definitely worth a try
2022-01-26T02:21:23 < karlp> well, honestly, the mA range is giving me enoughresolution, down to single uAs, so I can probably just ignore it, I was just trying to figure out what was going on.
2022-01-26T02:21:31 < fenugrec> so, no problem then
2022-01-26T02:21:36 < catphish> i had a similar issue yesterday, module in a car works when plugged in, but doesn't work if it's already plugged in when the ignition is turned on
2022-01-26T02:21:51 < catphish> either the switch bounce, or the rise time is killing the boot process
2022-01-26T02:22:54 < fenugrec> heh. I had a pcb with bodge wires on the back, it ~ worked but when probing around, the pressure from probing would short out a bodgewire
2022-01-26T02:22:56 < karlp> well, tried that, but as soon as I unshorted the leads it went back to this "1.1mA failure"
2022-01-26T02:23:06 < karlp> so, we'r egoing with "no problems! just dont use that range!"
2022-01-26T02:23:18 < karlp> manual and spec sheet says ~nothing about the other terminal :|

2022-01-26T11:28:44 < BlutigePforte> Good Morning!
2022-01-26T11:32:47 < PaulFertser> Hi
2022-01-26T11:36:08 < Steffanx> Is it?
2022-01-26T11:36:36 < BlutigePforte> Hi Paul, i was serching for jpa-. I found the Internet Site from Him, by searching for a Solution to Fix my xdm 2041 Bench Multimeter that is stuck on Progress bar 
2022-01-26T11:36:58 < karlp> BlutigePforte: so, have you fixed it for him? :)
2022-01-26T11:37:06 < BlutigePforte> no 
2022-01-26T11:37:27 < BlutigePforte> i got a foulty one for my self for cheap an now i try to fix it
2022-01-26T11:37:42 < BlutigePforte> an sorry for my bad english. but i am from germany
2022-01-26T11:41:31 < PaulFertser> BlutigePforte: and what do you want from him, the firmware binary?
2022-01-26T11:41:39 < BlutigePforte> But my Problem is, that i dont know so much of this Programming stuff. I have big Problems to understand what i need to fix this device
2022-01-26T11:42:03 < PaulFertser> BlutigePforte: please give more details. What exactly doesn't work and what you have tried already.
2022-01-26T11:42:10 < PaulFertser> BlutigePforte: and what equipment you have.
2022-01-26T11:43:01 < BlutigePforte> thanks for your request. i try to explain it. 
2022-01-26T11:44:28 < BlutigePforte> I got a not working relabelt OWON XDM 2041 Bench Multimeter, the Problem with this Device ist, wen you turn it on, it will stuck on the Progress Bar. 
2022-01-26T11:44:28 < PaulFertser> BlutigePforte: and whether you have read and understood all of https://github.com/PetteriAimonen/owon-xdm2041-info/tree/main/fix_boot_problems
2022-01-26T11:48:07 < BlutigePforte> this is the Problem. I try to Understand all this Stuff, but i dont have the Knowledge about this Programming Stuff and how to to it. So i hope somone can help me to understand what i need for this fix. 
2022-01-26T11:48:23 < PaulFertser> BlutigePforte: you need to ask more specific questions.
2022-01-26T11:50:45 < BlutigePforte> ok.  can somone tell me witch Operation System ( Linux, Windows or MAc ) an witch Programm i need to fix this Boot Problem with this device
2022-01-26T11:53:41 < PaulFertser> BlutigePforte: you said you read the last link but you didn't tell what solutions from it you've already tried.
2022-01-26T11:56:51 < karlp> that openocd patch required is pretty special :)
2022-01-26T11:57:25 < PaulFertser> Yes, but there're two things to check first none of which require knowledge of any Programming Stuff.
2022-01-26T11:57:51 < BlutigePforte> sorry but i dont have any Knowlege how to do this. I have checkt the flex cable connection. an this is ok 
2022-01-26T11:58:01 < PaulFertser> BlutigePforte: how did you check it exactly?
2022-01-26T11:58:43 < BlutigePforte> with a multimeter. i Probt it from connection to connention an it is in good condition
2022-01-26T11:59:12 < PaulFertser> BlutigePforte: that's essential information. Next question: have you tried exiting the bootloader by sending it the char sequence mentioned?
2022-01-26T11:59:47 < BlutigePforte> a friend of me testet the hardware also. and ther is no damage to anny component an the pcp board
2022-01-26T12:01:12 < BlutigePforte> an there is the Problem. i dont know what i need to do this. To send the char seqence to the boot loader
2022-01-26T12:01:22 < jpa-> BlutigePforte: hi
2022-01-26T12:01:26 < BlutigePforte> hi
2022-01-26T12:01:59 < BlutigePforte> this is wy i am here
2022-01-26T12:02:21 < PaulFertser> BlutigePforte: what's your background, are you studying electronics or something?
2022-01-26T12:02:24 < jpa-> you need a serial port cable between your PC and the XDM2041
2022-01-26T12:05:48 < BlutigePforte> PaulFertser No I am a Construcktion Worker, an a Hobby CNC Machinist. I even try to Fix everything that is usable for me. I bay somtimes brocken Things for cheap to fix it and use it for myself
2022-01-26T12:06:53 < PaulFertser> BlutigePforte: I see. First step would be to get serial port connection.
2022-01-26T12:06:56 < BlutigePforte> jpa- i have an USB to Serial 232 Adapter here only. My PC dont have an on board COM Port. Is this a problem
2022-01-26T12:07:47 < PaulFertser> BlutigePforte: no, if your adapter is really for RS-232 and not "TTL UART".
2022-01-26T12:07:59 < PaulFertser> Yes if it's not.
2022-01-26T12:09:49 < PaulFertser> To answer your question, https://github.com/PetteriAimonen/owon-xdm2041-info/tree/main/bootloader should run on any OS where python runs.
2022-01-26T12:12:24 < BlutigePforte> i have this cable here
2022-01-26T12:12:26 < BlutigePforte> https://www.amazon.de/gp/product/B00QUZY4UG/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
2022-01-26T12:13:28 < PaulFertser> BlutigePforte: looks suitable
2022-01-26T12:13:51 < PaulFertser> Also, funny, with all that fake gold plating.
2022-01-26T12:14:48 < jpa-> yeah, should work
2022-01-26T12:15:22 < jpa-> set to 115200 bps and try to talk to it
2022-01-26T12:15:23 < BlutigePforte> ok fist a big Thanks that you try to help me with my Problem. I really appreciat this. 
2022-01-26T12:16:00 < BlutigePforte> ok i think i have to install the python programm first
2022-01-26T12:16:15 < PaulFertser> BlutigePforte: yes, on whatever OS you like most.
2022-01-26T12:16:16 < BlutigePforte> i will do this quick 
2022-01-26T12:16:44 < jpa-> if you have some serial port terminal program like putty or hyperterm or whatever, you can try with it first also
2022-01-26T12:17:21 < BlutigePforte> sorry i dont have anny probgrams for this. so i have to install it first
2022-01-26T12:17:23 < PaulFertser> Yes, but it's unclear how to send \r\n with a random program.
2022-01-26T12:17:35 < jpa-> true
2022-01-26T12:18:14 < BlutigePforte> i am more the hardware guy. If i can find a repair instruction i am mostly able tho fix somthing. 
2022-01-26T12:20:14 < PaulFertser> Hardware repair changed over years. I've read how folks who were self-employed privately repairing washing machines and fridges discussed DIY portable flash dumping tools etc. You can't really do much with current hardware without also understanding a lot about software, like it or not.
2022-01-26T12:20:14 < BlutigePforte> ok now i have python 3.9.10 instalt
2022-01-26T12:21:09 < BlutigePforte> on windows 10 pro 
2022-01-26T12:24:23 -!- Guest9014 [~vit@chello085216193138.chello.sk] has joined ##stm32
2022-01-26T12:26:17 < BlutigePforte> ok can you perhaps provite me with the right comands that i have to typ in. in the Python Programm
2022-01-26T12:27:37 < PaulFertser> BlutigePforte: first thing would be to plug the USB in and check in the device manager what Serial port number it got (e.g. COM5).
2022-01-26T12:28:44 < jpa-> and you'll probably need to run   "pip install pyserial"  also
2022-01-26T12:28:49 < BlutigePforte> it hat the com port 3
2022-01-26T12:29:03 < PaulFertser> Guess windows python distro includes serial.
2022-01-26T12:29:35 < PaulFertser> BlutigePforte: then run "python3 xdm2041_bootloader.py COM3 XDM2041.bin"
2022-01-26T12:36:47 < BlutigePforte> ok dit i have do download the bootloader.py script? an wen yes were i have to store is......
2022-01-26T12:37:37 < PaulFertser> BlutigePforte: download the script and file XDM2041.bin from there, store in some directory both of them.
2022-01-26T12:38:24 < PaulFertser> For details probably ask someone who likes windows.
2022-01-26T12:39:21 < BlutigePforte> ok done
2022-01-26T12:40:34 < PaulFertser> Please use some pastebin (paste only a URL here) to show the output of the script when you run it like I suggested.
2022-01-26T12:40:50 < BlutigePforte> i have the xdm2041.bin and the xdm2041_bootloader.py script in a single folder named XDM an my desktop
2022-01-26T12:40:55 < PaulFertser> Good
2022-01-26T12:41:55 < Steffanx> Hah, finding ##stm32 when Googling for jpa-  . You're getting famous jpa-  😆
2022-01-26T12:43:08 < BlutigePforte> so i conectet the xdm2041 with the adapter cable to the pc an a have it on power on. 
2022-01-26T12:44:04 < PaulFertser> BlutigePforte: correct
2022-01-26T12:45:35 < BlutigePforte> so how can i now run it in the pyton. when i am right i have to connect to the folder in the pyton programm correct?
2022-01-26T12:46:02 < jpa-> open a command prompt
2022-01-26T12:46:15 < jpa-> shift + right click and select "Open command prompt here" or something like that
2022-01-26T12:46:22 < jpa-> might be "Open PowerShell here" nowadays :D
2022-01-26T12:46:55 < BlutigePforte> ok jpa this works
2022-01-26T12:47:15 < BlutigePforte> a got a powershell window now open in the right folder
2022-01-26T12:48:11 < jpa-> then run:    python3 xdm2041_bootloader.py COM3 XDM2041.bin
2022-01-26T12:52:34 < BlutigePforte> ok this will not work in the power shell window????  it say python can not be found. 
2022-01-26T12:52:56 < jpa-> try C:\Python\python    or something, depending where it is installed
2022-01-26T12:52:58 < PaulFertser> Means you didn't install python to be available system-wise.
2022-01-26T12:53:29 < jpa-> sometimes python3 also is called just "python" in windows
2022-01-26T12:53:34 < jpa-> and sometimes it is called "py"
2022-01-26T12:54:43 < BlutigePforte> ok py workt
2022-01-26T12:55:04 < BlutigePforte>  py xdm2041_bootloader.py COM3 XDM2041.bin

2022-01-26T12:57:54 < PaulFertser> Usually when I learn something about windows I forget about it quickly as I tend to do with the other things I find disgusting.
2022-01-26T12:57:54 < BlutigePforte> an now it is trying to enter the bootloader
2022-01-26T12:59:27 < jpa-> try restarting the multimeter
2022-01-26T12:59:59 < jpa-> but if it doesn't work, it may just mean that the bootloader is corrupt also
2022-01-26T13:02:20 < BlutigePforte> ok i think this is not working
2022-01-26T13:05:38 < BlutigePforte> wow 
2022-01-26T13:05:42 < BlutigePforte> it workt
2022-01-26T13:05:58 < BlutigePforte> it was succesfull 
2022-01-26T13:06:02 < BlutigePforte> wow 
2022-01-26T13:06:05 < BlutigePforte> coool 
2022-01-26T13:06:40 < jpa-> :)
2022-01-26T13:06:48 < BlutigePforte> for porpuse
2022-01-26T13:07:09 < BlutigePforte> wile the programm was trying to connect to the device 
2022-01-26T13:07:17 < BlutigePforte> i powert it off 
2022-01-26T13:07:26 < BlutigePforte> befor all this here 
2022-01-26T13:07:52 < BlutigePforte> i installt the manual switch for entering the bootloader on the xdm by power on 
2022-01-26T13:08:26 < BlutigePforte> then i presst the switch button, powert it on. nothing happend. 
2022-01-26T13:09:07 < BlutigePforte> then i powert the xdm off an on again without pushing the installt button to enter the bootloader
2022-01-26T13:09:13 < BlutigePforte> and then it workt
2022-01-26T13:10:46 < Steffanx> Does the xdm break randomly or does this happen when you mess with it?
2022-01-26T13:10:57 < Steffanx> Nevermind I'll read jpa- blog again 
2022-01-26T13:11:05 < BlutigePforte> i am so happy rith now. thanks for your help. i really really thankfull for your help
2022-01-26T13:11:07 < PaulFertser> BlutigePforte: backup your calibration data and save it while it works.
2022-01-26T13:11:19 < jpa-> BlutigePforte: ah, you installed BOOT0 switch? yeah, that is a different bootloader :)
2022-01-26T13:11:22 < PaulFertser> BlutigePforte: so that it would be easy to reflash later if anythinggoes wrong.
2022-01-26T13:11:33 < karlp> backing up calib requires building a patched openocd...
2022-01-26T13:11:34 < jpa-> Steffanx: the XDM2041 breaks when you sticker VC7055 sticker on it
2022-01-26T13:11:35 < BlutigePforte> Steffanx it was broken when i got it
2022-01-26T13:11:43 < PaulFertser> karlp: no, if it boots already
2022-01-26T13:12:07 < karlp> I thought you needed to break the read protection to dump the 2k calib?
2022-01-26T13:12:14 < Steffanx> BlutigePforte: you got it 2nd hand I assume?
2022-01-26T13:12:18 < jpa-> there is SCPI command to download calibration info
2022-01-26T13:12:21 < BlutigePforte> yes
2022-01-26T13:12:24 < PaulFertser> karlp: karlp: https://github.com/PetteriAimonen/owon-xdm2041-info/blob/main/bootloader/backup_calibration.py
2022-01-26T13:12:25 < jpa-> but that of course only works after it boots
2022-01-26T13:12:26 < karlp> jpa-: ah, ok.
2022-01-26T13:12:35 < BlutigePforte> i got it in perfect condition for 20 Euro 
2022-01-26T13:12:41 < PaulFertser> BlutigePforte: do the backup please
2022-01-26T13:12:49 < BlutigePforte> new price her is 180 Euro
2022-01-26T13:13:09 < BlutigePforte> an this Bench multimeter ist usefull for me 
2022-01-26T13:13:26 < BlutigePforte> so i dont want to trow it in the trash 
2022-01-26T13:14:08 < Steffanx> Don't forget to buy mr jpa a frozen pizza. 
2022-01-26T13:15:23 < Steffanx> You need a "donate me a beer" button on your website jpa-  (eventhough you perhaps don't drink beer)
2022-01-26T13:16:02 < Steffanx> I bet you'll have to learn to drink it when you add such donation button 
2022-01-26T13:16:16 < karlp> lol, ali is offering me delivery on 1 april...
2022-01-26T13:16:21 < karlp> that's... a lttle ways out...
2022-01-26T13:18:26 < jpa-> apparently someone made a bunch of rebranded VC7055 for the german market and they had some firmware bug that caused it to corrupt the flash pretty soon, rendering the device unbootable
2022-01-26T13:19:29 < BlutigePforte> jpa- this is what i have here
2022-01-26T13:19:38 < karlp> I wonder how many are just sitting on shelves as garbage...
2022-01-26T13:19:50 < BlutigePforte> it is a rebrandet xdm 2041 as Voltcraft 7055
2022-01-26T13:19:58 < karlp> heh, https://www.aliexpress.com/item/2054995985.html has a usb port, might make you think it's a usb-rs232... no. usb is only for power :)
2022-01-26T13:20:07 < jpa-> https://www.ebay.com/sch/i.html?_from=R40&_nkw=vc7055&_sacat=0&_sop=15   ebay is full of them
2022-01-26T13:20:11 < jpa-> "faulty, for parts only"
2022-01-26T13:20:42 < karlp> why pay full price for a faulty one?
2022-01-26T13:21:09 < karlp> I mean, it's $130 on eleshop...
2022-01-26T13:21:12 < karlp> fucking ebay
2022-01-26T13:21:13 < jpa-> they have not noticed that the XDM2041 price has dropped :)
2022-01-26T13:21:59 < karlp> how much was it?
2022-01-26T13:22:11 < karlp> fuckin almost midday again.
2022-01-26T13:22:25 < karlp> fixed my bug in my sleep last night. rememebered not to do things in freertos timer callbacks
2022-01-26T13:24:34 < jpa-> dunno, but they are trying to sell VC7055 for $280 new still
2022-01-26T13:26:20 < karlp> well, it is black.
2022-01-26T13:26:25 < karlp> that's certainly worth money
2022-01-26T13:31:58 < karlp> sloccount rough estimates that laks+freertos+stm32_wpan middleware is ~1.3k and cubeide hal w/freertos+stm32_wpan_middleware for ~same project is around 5k.
2022-01-26T13:35:53 < BlutigePforte> wow the VC7055 for 280 bucks???? are they crazy
2022-01-26T13:36:24 < BlutigePforte> here in Germany it only coast 180 Euro in Brand new
2022-01-26T13:37:25 < jpa-> and XDM2041 costs only 130 EUR + VAT, and doesn't brick itself :D
2022-01-26T13:37:36 < PaulFertser> BlutigePforte: did you manage to save calibration data now?
2022-01-26T13:38:30 < BlutigePforte> no not yet
2022-01-26T13:40:09 < PaulFertser> BlutigePforte: py backup_calibration.py COM3
2022-01-26T13:40:25 < PaulFertser> BlutigePforte: should create "calibration.bin" for you. Stash it somewhere safe just in case.
2022-01-26T13:41:29 < jpa-> that XDM2041 bootloader was a bit crazy looking in decompiled view.. 0x05 is the command to load main application, which causes the internal state machine to enter state 2 - and 0x02 is the command to load calibration, which enters state 5.. and for some reason "7" is the only kind of reply it knows to give
2022-01-26T13:42:33 < PaulFertser> :D

2022-01-26T13:44:18 < BlutigePforte> ok i got the calibration.bin downloaedet from the xdm 
2022-01-26T13:44:32 < BlutigePforte> thanks for your help. 
2022-01-26T13:44:40 < jpa-> :)
2022-01-26T13:45:15 < BlutigePforte> this is so nice from you. that you helpt me so much with my problem. 
2022-01-26T13:45:17 < PaulFertser> Guess you're lucky the bootloader wasn't damaged.
2022-01-26T13:45:19 < jpa-> that's now 5th VC7055 saved from garbage (that i know of)
2022-01-26T13:45:39 < PaulFertser> What's the statistics for them wrt bootloader?
2022-01-26T13:45:59 < BlutigePforte> yes of corse
2022-01-26T13:46:12 < jpa-> this is the first one restored using bootloader, because i only succeeded in reverse engineering it this month
2022-01-26T13:46:42 < BlutigePforte> and now you now that this is doing verry well 
2022-01-26T13:46:57 < jpa-> the bootloader apparently checks checksum of the calibration & settings area and forces entering bootloader if the checksum doesn't match - so when the main firmware makes a mistake in updating its config, it will be stuck in bootloader for ever
2022-01-26T13:47:09 < jpa-> or something like that
2022-01-26T13:47:13 < PaulFertser> jpa-: for for the previous devices people were probably comparing dumped binaries to see where the corruption was located
2022-01-26T13:47:35 < jpa-> PaulFertser: unfortunately the VC7055 has a different firmware version, so it has a lot of differences
2022-01-26T13:47:45 < PaulFertser> And different bootloader too?
2022-01-26T13:47:55 < jpa-> let's see
2022-01-26T13:48:40 < jpa-> no difference in bootloader area
2022-01-26T13:48:59 < jpa-> all have byte-per-byte identical first 10kB of flash
2022-01-26T13:50:39 < PaulFertser> Cool, so it's likely any such device can be restored with just an RS232 cable thanks to your work. Awesome.
2022-01-26T13:51:22 < jpa-> yeah, seems so
2022-01-26T13:51:37 < jpa-> i even think that just sending "\r\n\r\n" might be enough to restore them
2022-01-26T13:51:54 < jpa-> because that causes the bootloader to do something to the config page, probably setting some flag or updating the checksum
2022-01-26T13:55:19 < jpa-> if i wasn't lazy, i could of course just upload the whole flash image of a corrupted device and see what happens, but i would have to open up device and connect up stlink again, so no
2022-01-26T13:58:05 < PaulFertser> Probably worth editing the README there so that it would be obvious talking to bootloader should most probably work and there's likely no need for SWD and patched OpenOCD.
2022-01-26T13:58:12 < jpa-> yeah
2022-01-26T14:03:18 < jpa-> updated
2022-01-26T14:05:08 < BlutigePforte> Maybe you need the boot0 to 3,3v switch to.... i am not sure. but in the process when i thoug it dosnt work. i powert the Multimeter off, then i powert it on with the pusht switch for entering the internal bootloader. then i shut it off again an normal powert on. after this the python script workt by my device
2022-01-26T14:05:46 < jpa-> BlutigePforte: no, the BOOT0 switch is probably useless for this purpose
2022-01-26T14:06:12 < BlutigePforte> i dont know enough of this to say it for sure. 
2022-01-26T14:06:16 < jpa-> it activates the GD32 internal bootloader which is different and doesn't work with readout protection
2022-01-26T14:06:20 < jpa-> i do :)
2022-01-26T14:06:27 < BlutigePforte> ok 
2022-01-26T14:06:40 < jpa-> it could be that entering the bootloader needed a few reboots though
2022-01-26T14:06:56 < BlutigePforte> it was just a thought of me 
2022-01-26T14:07:05 < BlutigePforte> as a total noob for such thinks

2022-01-26T22:15:53 < fenugrec> yea it would've been surprising to route the cooling all the way to the front, but airflow must've been a constant challenge on that kind of machine
2022-01-26T22:15:57 < BrainDamage> yeah, that I figured
2022-01-26T22:16:21 < BrainDamage> intercooler has to be right next to turbo for best effectiveness

2022-01-26T23:13:31 < Steffanx> Would the generic question be something about exceptions?

2022-01-26T23:38:39 < zyp> kakium69, throw is effectively a «return to catchpoint»
2022-01-26T23:38:46 < Laurenceb> sup
2022-01-26T23:39:13 < Laurenceb> how come I can set a partition label with mkfs, i.e. its part of the filesystem, but also with parted?
2022-01-26T23:40:20 < kakium69> zyp: well that can be easily derived from examples. I'm thinking about stacks and threads now
2022-01-26T23:40:34 < karlp> nice. st apps don't even work with their current demos.
2022-01-26T23:40:44 < karlp> nrf and silabs apps work just fine
2022-01-26T23:40:57 < zyp> the advantage of exceptions is that you can easily do error handling without error states needing to be a part of the return types, and you get implicit RAII cleanup as the stack is unwound
2022-01-26T23:41:15 < zyp> the problem is just that C++ exceptions are typically slow
2022-01-26T23:41:38 < karlp> hrm, cypress/infineon fails as well. I wonder what the deal is :)
2022-01-26T23:42:30 < zyp> IIRC it has to look at your current pc register and search through the exception metadata to find the unwinding information
2022-01-26T23:42:59 < kakium69> zyp: does try have it's own stack?
2022-01-26T23:43:20 < karlp> best looking car is offroad converted karmann ghia's: https://engineswapdepot.com/?p=11253
2022-01-26T23:43:21 < zyp> no, just unwinding metadata
2022-01-26T23:43:30 < zyp> I mean, I guess it depends on the implementation
2022-01-26T23:43:48 < zyp> but I haven't seen any that do
2022-01-26T23:43:56 < kakium69> and the exception is stored in metadata?
2022-01-26T23:44:00 < zyp> yeah
2022-01-26T23:44:06 < kakium69> where is the metadata?
2022-01-26T23:44:19 < zyp> part of the advantage is that you don't get a lot of error handling overhead when there's no errors

2022-01-26T23:44:37 < kakium69> metadata is in stack?
2022-01-26T23:44:42 < zyp> but you pay for that in exceptions being expensive to handle, so you only want to use it for truly exceptional cases
2022-01-26T23:45:06 < zyp> unlike python where exceptions are cheap and used for common stuff like terminating iterators
2022-01-26T23:45:27 < zyp> metadata are in extab/whatever sections, probably stored in flash
2022-01-26T23:45:51 < zyp> exidx/extab
2022-01-26T23:47:06 < zyp> I considered enabling exceptions when I started with my coroutine stuff, because exceptions can be passed through futures as well
2022-01-26T23:47:34 < zyp> but I think I concluded they were probably still to expensive to be worth it
2022-01-26T23:47:42 < kakium69> does throw call software interrupt?

2022-01-26T23:49:45 < zyp> yeah, adds a bunch of size as well
2022-01-26T23:50:14 < zyp> I'll probably revisit and reevaluate at some point in the future
2022-01-26T23:52:40 < karlp> well, I've just tried a few of the ST demo apps, and none of them work with the ST droid apps (anymore)

2022-01-26T23:53:10 < zyp> so I take it you've got BLE working with laks and freertos?

2022-01-26T23:53:20 < zyp> nice

2022-01-26T23:53:28 < karlp> very c style c++ though....
2022-01-26T23:53:41 < BrainDamage> kakium69: however, assertions are good to put in your program to catch pathological cases
2022-01-26T23:53:42 < karlp> rough estimate is ~1300 lines vs 5000 lines of hal shits
2022-01-26T23:54:16 < zyp> well, yeah, c++ is pretty much a superset of c, so you might as well use what you like and ignore the rest
2022-01-26T23:54:17 < karlp> I've got to do some low power work, but thats (from what I've followed and avoided) "just" copying the custom freertos sleep handler

2022-01-27T00:45:56 < zyp> you forgot one of the -> in flash.cpp, which broke my build :)

2022-01-27T01:34:26 < karlp> oh, while I remember, you cgit instance says that the clone links are https://git.jvnv.net/git/laks and git://git.jvnv.net/laks
2022-01-27T01:34:33 < zyp> well, it looked reasonable and apart from the -> it doesn't appear to break my stuff

2022-01-27T01:51:37 < zyp> ok, I fixed the http git thing, I think
2022-01-27T01:52:26 < zyp> dumb shit didn't set GIT_HTTP_EXPORT_ALL correctly
2022-01-27T01:54:00 < zyp> apparently the normal way of using it is to set it to an empty string, and I guess an update of something got the brilliant idea of optimizing out empty environment variables
2022-01-27T01:54:34 < karlp> software *shrugs*
2022-01-27T01:55:08 < zyp> still might move to github eventually :)
2022-01-27T01:56:15 < karlp> so I bought a ch582-evt board.... which may be https://github.com/openwch/ch583/blob/main/EVT/PUB/CH583EVT%20Evaluation%20Board%20Manual.pdf or may be ~similar.
2022-01-27T01:56:27 < karlp> so I get to go and throw riscv silly shit at laks one day too :)
2022-01-27T01:56:48 < zyp> :)
2022-01-27T01:56:55 < zyp> that's the one with 10m phy and 1g mac?
2022-01-27T01:57:03 < karlp> no, that's out of stock, I wanted that too
2022-01-27T01:57:09 < karlp> that's the ch32v307
2022-01-27T01:57:14 < zyp> ah, right
2022-01-27T01:57:16 < karlp> this is the BLE one :)
2022-01-27T01:57:28 < karlp> if I'm goign to be pro ble.... (which I'mfucking not)
2022-01-27T01:57:35 < zyp> haha
2022-01-27T01:59:38 < karlp> lcsc sys I've got the 582-evt, but all text talks about a 583-evt, which http://wch-ic.com/products/categories/53.html?pid=63 says is "448k flash + 32k sram + 32k dataflash" vs "448k flash + 32k sram + 544k dataflash"
2022-01-27T01:59:46 < karlp> and I've got no idea what "dataflash" means in this context.
2022-01-27T02:04:44 < karlp> bit lame though, apparently only the 583 supports 1.8v,
2022-01-27T02:04:52 < karlp> like, why would you make _that_ a differentiator?
2022-01-27T02:05:28 < karlp> (but still provide _two_ usb controllers?!)
2022-01-27T02:07:07 < karlp> ch583: two usb, two spi, 1.8V, 544k dataflash. ch583: two usb, _one_ spi, 2.5V, 32k dataflash.
2022-01-27T02:07:46 < karlp> ch581: _zero_ usb, _zero_ i2c.
2022-01-27T02:07:50 < karlp> weird matrix.
2022-01-27T02:07:56 < karlp> but whatevers
2022-01-27T02:09:30 < karlp> oh, I got the gd32vf103c-start board too, the giga-nucleo

2022-01-27T12:25:12 < karlp> zyp: took a morning doing a little riscv datasheet mining for a distraction.
2022-01-27T12:25:45 < karlp> the current riscv.yaml does a match on "rv32imac" and then sets the interrupts.  we're going to need to be finer grained with that.
2022-01-27T12:26:24 < karlp> tthe ch32v30x and ch583 have a "rv32imac" but its "riscv-v4a" and "v4f" and the system exceptions are not the same as (the gd32v?) ones you have there at the moment.
2022-01-27T12:26:39 < karlp> ecall-u and ecall-m are in different slots even.
2022-01-27T12:30:12 < karlp> and they all have "PFIC" not clic or plic, if I'm reading it right
2022-01-27T12:32:22 < karlp> we might want something like "cpu" and "isa" to be different?
2022-01-27T12:36:42 < zyp> maybe, depends a bit how reusable everything is
2022-01-27T12:37:05 < zyp> I mean, whether something is a vendor special or used across vendors

2022-01-27T12:41:06 < karlp> chinese versions are legible enough to compare the system vectors at least.

2022-01-27T13:52:19 < karlp> gets confused about which header to try and open for definitions :(
2022-01-27T13:55:27 < karlp> zyp: just something like https://github.com/karlp/laks/commit/ff7504a20e9d8916f93aafcffc9d0ec37a20d562 seems reasonable to take gd32 out of squatting the entire "rv32imac" cpu name, and allows https://github.com/karlp/laks/commit/7d1e87bc26226aa55bb2c67f86926c92197d159e for alternative cores to come in?
2022-01-27T13:55:48 < jadew> had an exchange with DHL... they kept asking me to send them a piece of paper with the name of the products
2022-01-27T13:56:02 < jadew> and I was like "that is the name of the product" then they were like "not the code, the name"
2022-01-27T13:56:07 < jadew> ffs... I never named them anything else
2022-01-27T13:56:16 < jadew> just use the fucking paper I already sent you
2022-01-27T13:56:55 < jadew> I ended with, if the legislation hasn't changed, present it as it is, because it worked fine the last 30 times
2022-01-27T13:57:03 < jadew> ""
2022-01-27T13:57:11 < zyp> karlp, I think it's reasonable for the cpu parameter to match what you pass to -mcpu, and then I figure we can add a second one to describe what kind of interrupt setup it has
2022-01-27T14:01:56 < karlp> that would work too.
2022-01-27T14:02:00 < zyp> gd32v already splits out a third of the interrupt setup (irq), leaving exception/internal common
2022-01-27T14:02:05 < karlp> this was just kinda having a diversion mroning...
2022-01-27T14:02:14 < karlp> wanted to start seeing what it would look like.
2022-01-27T14:02:51 < karlp> with what I've got, the -march stuff just gets duped, when it really is just the irq setup.
2022-01-27T14:03:03 < zyp> looking at your wch definitions, it looks like they're cloning the basics of NVIC
2022-01-27T14:03:04 < karlp> so yeah, a second meta term is probably better.
2022-01-27T14:03:36 < zyp> probably gonna need its own startup code if that's the case
2022-01-27T14:04:12 < karlp> yeah, I expect there may be more "joy" ahead in this...
2022-01-27T14:06:43 < zyp> hmm, I wonder if I forgot to merge part of the startup code for gd32v
2022-01-27T14:10:07 < zyp> ah, yes, I got this as part of my sandbox project, not yet merged into laks itself: https://paste.jvnv.net/view/RdOQr
2022-01-27T14:12:58 < zyp> if the PFIC is like the NVIC and does stack initialization, it can probably reuse the startup code as is and just use the NVIC way of building the vector table
2022-01-27T14:15:21 < karlp> will have to look closer,
2022-01-27T14:15:33 < karlp> register layoout for configuring tthings is completely differentat least.
2022-01-27T14:15:55 < karlp> but the startup portion I'd not really looked at.  there's example code to compare with I guess.
2022-01-27T14:16:15 < karlp> ok, lol. I've got the "API" to use for remote control of this device, and it's a fucking .ocx
2022-01-27T14:16:26 < karlp> what fucking century is this?!
2022-01-27T14:16:41 < karlp> why would you not just provide the _actual_ api, isntad of a wrapper?!
2022-01-27T14:17:00 < karlp> their hardware is also nearly double the price, so fuck these guys.
2022-01-27T14:23:16 < zyp> how many freertos tasks are you using? main starts a blink task and task_ble, and then it looks like ble task kicks off a few more
2022-01-27T14:23:38 < karlp> yeah, I sort of built it up copying st for starters.
2022-01-27T14:24:15 < karlp> in what I've setup, task_ble is provided by "a component" and can do whatever it wants
2022-01-27T14:24:38 < karlp> calling task_ble_setup() will create two new tasks, one for shci and one for hci, and those notify back to you.
2022-01-27T14:24:58 < karlp> I'm pretty sure the shci and hci tasks can be combined with a bit of thought, but ST has them separate.
2022-01-27T14:25:22 < karlp> those are "transport handling" tasks, and the task_ble is then your "user app" task do your own stuff.
2022-01-27T14:25:44 < zyp> I'm thinking about how much work it'd be converting them to be coroutines instead
2022-01-27T14:25:55  * karlp plugs his ears and sings lalalal
2022-01-27T14:25:58 < zyp> :)
2022-01-27T14:26:11 < karlp> I already know which chunk of ST code to rip out next though,
2022-01-27T14:26:30 < karlp> there's a chunk of svc/*.c helpers that all look to be pretty useless and force a certain style on you.
2022-01-27T14:26:51 < karlp> so those would be easy to rip out, leaving just the (s)hci mailbox stuff 
2022-01-27T14:27:02 < karlp> but that's a distraction
2022-01-27T14:27:22 < karlp> low power this afternoon, then back to less public stuff using this really.

2022-01-27T14:38:00 < zyp> riscv in a regular microcontroller doesn't really do much for me, it's better than the xtensa shit in other esp32, but more of a hassle to work with than cortex-m
2022-01-27T14:38:17 < ventYl> I expected that risc-v is now much like ARM was before cortex introduction. a pile of incompatible and inconsistent devices
2022-01-27T14:38:32 < ventYl> and that's probably ok for now

2022-01-27T14:38:48 < zyp> kind of, yes
2022-01-27T14:39:36 < zyp> the open nature of risc-v makes inconsistence an inevitability
2022-01-27T14:40:22 < ventYl> I hope that there will be some kind of consensus on how much incompatible you can get while still making useful product

2022-01-27T14:52:25 < karlp> openocd/gdb don't like debugging code before the threads have started.
2022-01-27T14:52:47 < karlp> I can't step or anything sane if I have rtos mode enabled in openocd, but I don't know who's fault it is...
2022-01-27T14:53:05 < karlp> have to disable rtos support in oocd and restartbefore I can step through pre-os tasks...
2022-01-27T14:54:24 < Mangy_Dog> i was about to consider using the f103c6 im now using in my door portion of the tricorder, to take over touch sensing as i have a bunch of gpio spare on that chip now. But i get the feeling its not as simple as using the mpr121
2022-01-27T14:54:44 < Mangy_Dog> that im already using for touch sensing buttons
2022-01-27T14:56:25 < ventYl> karlp: I have investigated that a tiny bit and if rtos mode is enabled, generally some heuristics is done to tell what RTOS is running and where to obtain thread information. if you try to use this with threading in not yet initialized state, it will probably cause all kind of unwanted effects
2022-01-27T15:02:08 < karlp> ventYl: yeah, I figured itout, just not sure who to blame :)
2022-01-27T15:02:30 < karlp> does f1 even have a touch controller?
2022-01-27T15:02:36 < karlp> plenty of other stm32s do.
2022-01-27T15:02:54 < ventYl> karlp: IIRC gdbserver implementation inside oocd
2022-01-27T15:03:31 < ventYl> a lot of assumptions were put into thread support code, especially the portion which examines various RTOSes
2022-01-27T15:08:05 < karlp> zyp: this feels like volatile gone wrong, is that c++ and volatile hurting me? https://paste.jvnv.net/view/P9Q2b
2022-01-27T15:08:21 < karlp> reading mmioptr(RTC) I can see the TR changing nicely, 
2022-01-27T15:08:38 < karlp> but accessing just ->TR itself I get a static value that _sometimes_ updates?
2022-01-27T15:09:18 < karlp> gonna have luunch and think about it...
2022-01-27T15:09:28 < zyp> I have a suspicion
2022-01-27T15:10:44 < zyp> I think the registers might be latched so you can read them atomic
2022-01-27T15:10:56 < zyp> because gdb doesn't give a fuck about atomic
2022-01-27T15:17:44 < zyp> «To ensure consistency between the 3 values, reading either RTC_SSR or RTC_TR locks the values in the higher-order calendar shadow registers until RTC_DR is read.»

2022-01-27T15:26:08 < karlp> I wanted to see the ssr increase and slowly tick over.
2022-01-27T15:26:14 < karlp> weird, but whatever...
2022-01-27T15:39:19 < zyp> I guess maybe the issue is you're reading DR first, so it unlocks, and then immediately relocks before it has time to update
2022-01-27T15:41:08 < GenTooMan> right you don't want to cause roll over in the higher order registers because of the asynchronous nature of an RTC or for that matter any clock in the system

2022-01-27T15:58:05 < karlp> I've got some other flag that's probably not being checked, because I have to step through init, otherwise it doesn't set the calendar properly either.
2022-01-27T16:24:13 < GenTooMan> you have the same issue when updating an RTC as well.
2022-01-27T16:26:14 < GenTooMan> it's a problem if you don't stop the registers from updating whilst setting them.  You can have disturbing errors occur.  Anyhow the RTC in any system requires a lot of care to be kept correct. :D
2022-01-27T16:32:33 < karlp> ok, so just reading ssr, tr, dr works, based on the locking, no need for shadow bypass.

Random tivia most people think Vista was a flop because the developers for Vista messed up. Turns out the developers for MSVC++ actually messed up <- fact, the optimizers they had implemented ignored the keyword volatile which inflicted "bugs" into drivers for Vista. 
2022-01-27T16:52:18 < GenTooMan> that did a lot of damage. The irony is that GCC and Intel's compiler both had the same error.

2022-01-27T22:05:23 < jpa-> vatrat: does STM32F1 even have any real DSP instructions?
2022-01-27T22:05:40 < vatrat> supposedly yes, it's the lowest one that does
2022-01-27T22:05:56 < jpa-> Cortex-M4 and M7 do, but AFAIK M3 does not
2022-01-27T22:06:03 < vatrat> But I haven't actually checked, I got busy after I realized M3 had them two days ago
2022-01-27T22:06:20 < jpa-> unless you count "multiply and add" as DSP instruction - but even that is not SIMD
2022-01-27T22:06:36 < vatrat> hm, yeah
2022-01-27T22:06:52 < vatrat> m4 has true
2022-01-27T22:07:36 < vatrat> m3 has "three Thumb-1 instructions, all Thumb-2 instructions, hardware integer divide, and saturation arithmetic instructions."
2022-01-27T22:09:03 < jpa-> the M4 SIMD instructions are nice, if they do what you need them to do - but it is not particularly flexible and because they are at most 4x SIMD the speedup is not huge

2022-01-28T00:03:24 < kakium69> templates make my smooth brain hurt
2022-01-28T00:03:45 < kakium69> is it some sort of search-replace mechanism
2022-01-28T00:04:37 < bitmask> just write the same thing over for every possible type
2022-01-28T00:05:48 < kakium69> https://forum.arduino.cc/t/trick-for-getting-port-sfr_io-address/392012/2 and in this it's not used to implement functions for different types but for different gpio pins of avr8
2022-01-28T00:05:57 < kakium69> and it has struct
2022-01-28T00:06:45 < kakium69> some tutorial told me there is function templates and class templates.. which one this is?
2022-01-28T00:08:04 < kakium69> this is why I'm pondering if it has some sort of more universal search-replace mechanism
2022-01-28T00:08:47 < karlp> qyx: hehe, I was just looking at whether Ishould try just using lptim instead of figuring out this janky rtc sleep durationdetection via rtc->ssr shits
2022-01-28T00:09:17 < bitmask> i mean in c++ structs are basically classes with the difference between things are public by default
2022-01-28T00:09:18 < karlp> my _final_ project can't use anything lower than lpsleep anyway, so lptim would be fine, and it would sure as shit be simpler :)
2022-01-28T00:09:34 < karlp> but even witih tickless, you still have a tick, you just don't have irqs every tick...
2022-01-28T00:09:59 < karlp> so do you still hve tick at 1khz in your "tickless"? (I bet you do...)
2022-01-28T00:10:55 < karlp> kakium69: that just looks like a worse version of laks :)
2022-01-28T00:10:58 < kakium69> bitmask: I know
2022-01-28T00:11:37 < bitmask> i think its just a quick way to create the structs for only the pins you need?
2022-01-28T00:11:38 < qyx> karlp: I am feeding freertos with 1 kHz "virtual clock" (32768 / 32) for the purpose of calculating sleep times, timeouts, etc.
2022-01-28T00:12:34 < karlp> yeah, you're using tickless mode 2, with your own vSuppressTicksAndSleep shit that just uses lptim permanently, isntead of the built in version that uses systick?
2022-01-28T00:12:34 < bitmask> are you trying to find out how it works under the hood?
2022-01-28T00:12:35 < qyx> and I call fresrtos's sys tick handler at that rate
2022-01-28T00:12:48 < karlp> right.
2022-01-28T00:12:49 < kakium69> bitmask: operation of the template yes
2022-01-28T00:12:53 < qyx> but only when not sleeping
2022-01-28T00:13:04 < karlp> qyx: what does that actually give you?
2022-01-28T00:13:08 < bitmask> ok have fun with that, i dont know, i dont use templates much
2022-01-28T00:13:21 < karlp> oh, lptimer keeps running properly lower than systick, duh
2022-01-28T00:13:39 < qyx> yes, lptim keeps running
2022-01-28T00:13:45 < qyx> I don't enable systick at all
2022-01-28T00:13:53 < kakium69> bitmask: I will
2022-01-28T00:14:14 < karlp> qyx: you cna run lptim down to stop2,
2022-01-28T00:14:33 < karlp> nominally, I can run the wakeup down to "shutdown"
2022-01-28T00:14:41 < karlp> but it's starting to feelacademic :)
2022-01-28T00:15:09 < karlp> lptim1 would be fucking simple, just replace systick with lptim1 and clone the built int implementation.
2022-01-28T00:15:40 < qyx> tbh I don't remmeber exactly how did i implement that thing, I released it from the brain once it worked sufficiently good
2022-01-28T00:16:31 < qyx> I think you could simply replace systick with lptim and don't bother with tickless shit
2022-01-28T00:16:39 < qyx> and wakeup at 100 Hz for example
2022-01-28T00:17:09 < qyx> also it has some nasty implications, you have to maintain a "wake lock"
2022-01-28T00:17:23 < qyx> you cannot enter stop when any communication is ongoing
2022-01-28T00:18:02 < qyx> so I am posponing it until usart/spi/i2c/whatever tx registers are empty
2022-01-28T00:19:02 < karlp> oh, yeah, the wakelocking is all fine, i know I hve to do that, I've got even more for the ble shits for that,

2022-01-28T00:20:08 < karlp> I don't even know how this st code thinks it can work, wakeup timer has a range of ~0.5ms up to 30 seconds, and they use the _sub second_ counter to work out if they work up early, and by how much.
2022-01-28T00:20:14 < karlp> which... wraps every second
2022-01-28T00:20:36 < karlp> so if they asked to sleep for 5 seconds, they can't tell if they woke up after 1,2,3 or anything.
2022-01-28T00:22:34 < karlp> yeah, it's fuckingbusted
2022-01-28T00:22:38 < karlp> fucking arseholes.
2022-01-28T00:23:04  * karlp should probably test that though, should be straight forward...
2022-01-28T00:26:48 < zyp> kakium69, that code is kinda stupid
2022-01-28T00:27:02 < kakium69> is it?
2022-01-28T00:27:30 < kakium69> show your laks gpio pin abstraction
2022-01-28T00:27:55 < zyp> https://cgit.jvnv.net/laks/tree/gpio/stm32_gpio.h?h=dev_v2#n125
2022-01-28T00:28:58 < kakium69> why is that arduinoforum post code using template anyway?
2022-01-28T00:29:17 < zyp> yeah, that's the thing that's kinda stupid
2022-01-28T00:29:47 < zyp> it's passing in pin/port as template arguments instead of regular constructor arguments
2022-01-28T00:30:02 < kakium69> to gain nothing?
2022-01-28T00:30:15 < karlp> to use templates!
2022-01-28T00:30:37 < zyp> well, in the basic case they'll both inline and fold to a simple register write
2022-01-28T00:30:59 < kakium69> no doubt
2022-01-28T00:31:53 < karlp> heh, now I hav eot add lptim support to laks for the wb :)
2022-01-28T00:32:33 < zyp> one could argue that the template code is a bit stricter on forcing the code to be inlineable, but it's also a bit more hassle to use it since all functions taking pins as argument now also have to be template functions
2022-01-28T00:33:44 < zyp> karlp, I assume it's not register compatible with regular timers, so the most obvious way is probably to add a timer/stm32_lptim.h
2022-01-28T00:36:50 < karlp> yeah, already done, I'm a pro at this now...
2022-01-28T00:36:56 < zyp> :)
2022-01-28T00:37:14 < karlp> welll, I actuallyjust added it as new type in timer/timer, didn't really feel like a need to make a new file for it, but...

2022-01-28T00:38:06 < karlp> if I have extern "C" { some_required_impl_called_by_c_land() { fancy_c++_method(); } }
2022-01-28T00:38:17 < karlp> is that "free" or do I get a second function call?
2022-01-28T00:39:30 < zyp> if you're calling a method, the this pointer is an implicit first argument
2022-01-28T00:40:44 < zyp> but it depends, you might end up with the entire method inlined in the C function
2022-01-28T00:41:29 < zyp> e.g. if you have like: extern "C" void led_on() { led_pin->on(); }
2022-01-28T00:42:01 < zyp> you should get the equivalent of void led_on() { PORTx->BSRR = 1 << y; }
2022-01-28T00:42:40 < karlp> I think this might be optimziation for later...
2022-01-28T00:42:45 < zyp> yeah
2022-01-28T00:44:16 < zyp> if you're calling something with an identical signature, you could in theory get a symbol alias, but I don't think the compiler will do that on its own, so best case is probably a direct tail call

2022-01-28T00:51:58 < zyp> gcc will inline if the method is defined in the same translation unit, and tailcall if not available for inlining
2022-01-28T00:53:15 < zyp> in other words, it's probably doing the right thing already

2022-01-28T00:56:38 < zyp> tickless scheduling is something I want to implement in laks, so having a test case for that is maybe a good excuse for me to port your code to coroutines later :)

2022-01-28T05:23:33 < brdb> okay turns out you need to do the following in CubeMX: https://i.imgur.com/C7mfOuI.png
2022-01-28T05:24:39 < brdb> then additionally for GCC the Makefile has to be updated to include the relevant libarm_cortex*_math.a file under 'Drivers/CMSIS/Lib/GCC/libarm_*.a'
2022-01-28T05:24:59 < brdb> after LIBDIR is updated to that ^ it will compile without throwing a fit about unimplemented functions
2022-01-28T05:25:58 < brdb> i'm not entirely sure why ST has their own carbon-copy of the CMSIS DSP arm_math.h library, the alternative is to simply include the CMSIS/DSP/Include directory instead of using ST's "Middleware" carbon-copy
2022-01-28T05:30:11 < brdb> yeah just use CMSIS' DSP includes and skip that whole imgur screencap middleware download to avoid the duplicate header from STMicro

2022-01-28T16:19:19 < kakium69> zyp: why pin class constructor is constexpr
2022-01-28T16:21:35 < kakium69> do you have code example were these gpio classes are used?
2022-01-28T16:22:12 < ventYl> i guess because it is all derivable at compile time
2022-01-28T16:23:16 < karlp> kakium69: https://github.com/karlp/l2-simple/blob/main/src/main.cpp#L524 and look for the "led_xxx" usages...
2022-01-28T16:27:43 < kakium69> where is gpio initialized?
2022-01-28T16:29:45 < kakium69> auto led_g = GPIOB[0]; this?
2022-01-28T16:32:33 < kakium69> is GPIOB a pinArray type?
2022-01-28T16:33:00 < karlp> yup
2022-01-28T16:33:44 < karlp> well, kinda.
2022-01-28T16:33:54 < karlp> the GPIOB class instance has a [] operator defined on it...
2022-01-28T16:34:41 < karlp> https://github.com/karlp/laks/blob/dev_v2/gpio/stm32_gpio.h#L254
2022-01-28T16:35:42 < kakium69> yes
2022-01-28T16:35:53 < kakium69> I saw it
2022-01-28T16:36:42 < mawk> nice magic
2022-01-28T16:36:50 < karlp> thank zyp
2022-01-28T16:37:05 < kakium69> class STM32_GPIO_v2_t : public mmio_ptr<STM32_GPIO_reg_v2_t> what does this line do?
2022-01-28T16:37:13 < mawk> declare a class
2022-01-28T16:37:15 < kakium69> what is : ?
2022-01-28T16:37:18 < mawk> inheritance
2022-01-28T16:37:25 < kakium69> oh
2022-01-28T16:37:31 < mawk> it's the class STM32_GPIO_v2_t that inherits from mmio_ptr<STM32_GPIO_reg_v2_t>
2022-01-28T16:37:47 < kakium69> what is <> ?
2022-01-28T16:37:48 < mawk> and mmio_ptr is presumably a "smart pointer" class that points to a type STM32_GPIO_reg_v2_t here
2022-01-28T16:37:52 < mawk> it's template instanciation
2022-01-28T16:38:06 < mawk> mmio_ptr is like a class factory, and you give it STM32_GPIO_reg_v2_t as a parameter
2022-01-28T16:38:23 < kakium69> mmio_ptr is template?
2022-01-28T16:38:28 < mawk> yes
2022-01-28T16:38:35 < mawk> mmio_ptr is a class template, that takes 1 type parameter
2022-01-28T16:39:08 < mawk> so mmio_ptr<STM32_GPIO_reg_v2_t> is a class; which is instanciated from the template
2022-01-28T16:41:02 < karlp> what you can't see in github is the generated code..
2022-01-28T16:41:18 < kakium69> where is mmio_ptr?
2022-01-28T16:41:29 < karlp> which looks like this: https://paste.jvnv.net/view/HOOdS
2022-01-28T16:41:36 < kakium69> maybe mmio/mmio.h
2022-01-28T16:41:38 < mawk> https://github.com/karlp/laks/blob/dev_v2/mmio/mmio.h#L6
2022-01-28T16:41:49 < mawk> T is the parameter for the template here
2022-01-28T16:41:59 < mawk> in karlp's example, T = STM32_GPIO_reg_v2_t
2022-01-28T16:42:06 < mawk> which is presumably a uint32_t or something like that
2022-01-28T16:42:19 < mawk> or even a complex type, it can be anything
2022-01-28T16:42:28 < karlp> they're the structs that have the register map, see stm32_gpio.h...
2022-01-28T16:42:50 < karlp> it overlays the struct in the right place in memory
2022-01-28T16:42:56 < mawk> I see
2022-01-28T16:43:19 < kakium69> mawk: it's a struct with registers
2022-01-28T16:44:27 < ventYl> actually not. it pretends to be a struct at address where actual register lives

2022-01-28T16:44:44 < ventYl> so you can work with it as if it was a class
2022-01-28T16:45:03 < karlp> structs == classes...
2022-01-28T16:45:11 < karlp> just public vs private members by default.
2022-01-28T16:45:26 < kakium69> that reminds me.. does structs have constructors?
2022-01-28T16:45:35 < ventYl> may have
2022-01-28T16:45:40 < kakium69> interestings
2022-01-28T16:45:53 < mawk> struct is just like class kakium69 
2022-01-28T16:45:58 < mawk> except that everything is public by default
2022-01-28T16:46:01 < kakium69> I know
2022-01-28T16:46:19 < mawk> yes
2022-01-28T16:46:19 < ventYl> memory representation os struct and class is the same, until you introduce virtual methods
2022-01-28T16:46:28 < mawk> so then you can have a constructor if you want in the struct
2022-01-28T16:46:31 < mawk> or operators, or anything
2022-01-28T16:46:40 < ventYl> if class doesn't have any virtual method, directly, or inherited, then it is just a struct with methods
2022-01-28T16:46:52 < karlp> heh, at 1.8V, the green led on my nucleo is 40uA on :)
2022-01-28T16:47:17 < kakium69> it's barelly Vf
2022-01-28T16:48:12 < mawk> even at 1µV the led is on, according to veritasium guy
2022-01-28T16:52:37 < kakium69> using mmio_ptr<STM32_GPIO_reg_v1_t>::ptr;
2022-01-28T16:53:00 < kakium69> that is to only use ptr() method?
2022-01-28T16:56:53 < mawk> where is that written kakium69 ?
2022-01-28T16:56:57 < mawk> "using" depends on context
2022-01-28T16:57:04 < mawk> but it can mean that the ptr method is "imported" from the parent

2022-01-28T17:05:55 < karlp> it gets used here for isntance: https://github.com/karlp/laks/blob/dev_v2/wpan/stm32_ipcc.h#L34

2022-01-28T19:06:53 < karlp> yeah, shitting me to tears, have cube demos that work, can't for the life of me work out what else is different.
2022-01-28T19:07:21 < karlp> was perhaps trying to copy/paste to glory to finish the week, instead of doing it by hand, but bleh
2022-01-28T19:08:10 < karlp> and debugging it is a fucking nightmare as well, as it a) uses power and b) fucks up all the timing no end.
2022-01-28T19:53:08 < mawk> yes you avoid it karlp 
2022-01-28T19:53:17 < mawk> but the other of that code made ptr public to make it possible

2022-01-28T19:55:10 < fenugrec> hmmm... fixing an IGBT driver here, and it has two back-to-back, 18V zeners, between gate and emitter. With 5% tolerance , that means Vge could easily be up to 19.5V , and these IGBTs are of course limited to +- 20V on the gate !! 
2022-01-28T19:55:58 < jpa-> so, 0.5V of margin?
2022-01-28T19:55:59 < fenugrec> they must've wanted to get the absolute lowest possible Vce_sat ... sounds super sketchy for a production though
2022-01-28T19:56:07 < fenugrec> yes !
2022-01-28T19:56:31 < jpa-> it's not like the IGBTs burn at exactly 20V
2022-01-28T19:57:02 < fenugrec> one would hope not, indeed. But the gain is marginal beyond 15-16V on the gate
2022-01-28T19:57:09 < fenugrec> on this particular module at least
2022-01-28T19:58:25 < fenugrec> (this board drives two IGBT half-bridges, 2 zeners per gate, and all 8 zeners were dead. 5 shorts, 3 open : )

2022-01-28T23:14:22 < karlp> man, try and do "nice " things in c++ and it's just a disaster :)
2022-01-28T23:14:42 < karlp> back to the internets
2022-01-28T23:17:54 < karlp> I wanted to have IHandler = SomeHandler() butwithout using new, but apparently c++ is just fucking complicated.
2022-01-28T23:18:03 < karlp> and the right approach is "do it differentyly"
2022-01-28T23:18:32 < BrainDamage> is somehandler a class?
2022-01-28T23:18:39 < karlp> well, I was doing it yeah,
2022-01-28T23:19:11 < karlp> I don't think I can be helped on irc, I think I have to just experiment
2022-01-28T23:19:35 < karlp> all the answer on the intermnet involve new though, and I don't think I realyl need/want that, so I've just got to set it up differently.
2022-01-28T23:19:44 < BrainDamage> if ihandler is not a pointer, and your class a non virtual ctor, you should be able to instantiate with just classname instancename,
2022-01-28T23:20:39 < BrainDamage> so like hander IHandler();
2022-01-28T23:21:21 < karlp> yeah, I tried having Handler h; {switch(mode) { case: h = ImplA(); case h = ImplB()} 
2022-01-28T23:21:27 < karlp> at least, that's the concept I was going for,
2022-01-28T23:24:16 < BrainDamage> and handler is a class for which implA and implB are childs?
2022-01-28T23:24:30 < BrainDamage> does hander have all non virtual methods?
2022-01-28T23:24:49 < karlp> I tried having handler be pure virtual, to be "an interface"
2022-01-28T23:25:37 < karlp> it's ok. I've just had a somewhat dissapointing end to the week and learning c++ the hardway probably isn't really helping.
2022-01-28T23:25:56 < BrainDamage> you cannot instantiate a class that's pure virtual
2022-01-28T23:26:05 < karlp> and my youngest daughter decided to draw on both my monitors while we were watching dinner, so I've got scratchs on both of them now, sothat's really improving tings too
2022-01-28T23:26:15 < karlp> I didn't want to, I just wanted a poitner/reference really,
2022-01-28T23:26:40 < karlp> but Handler *h; h = ... requires new, and I was led to believe I didn't want dynamic memory allocation, 
2022-01-28T23:26:44 < BrainDamage> pointer you can do, but then it's new
2022-01-28T23:26:53 < karlp> and I really don't whwne I'm just using to make syntax nicer.
2022-01-28T23:27:14 < karlp> and Handle r &h; h = &Impl() is errors about "cann't take ref of rvalue" or something
2022-01-28T23:27:39 < karlp> and it's c++ errors, so you get a bit stuck, "am I on the right path, but not there yet, or completely wrong" :)
2022-01-28T23:28:13 < karlp> but I know that given all I'm trying to do is switch case on a bunch of versions of the same functions, I don't want things that require "new"
2022-01-28T23:29:20 < karlp> I'm going to simplify it and play on the dsktop a bit and learn this a bit more.
2022-01-28T23:29:31 < BrainDamage> basically, refs should never be non 0 pointersù
2022-01-28T23:29:53 < BrainDamage> and that's enforced by the compiler

2022-01-29T02:49:36 < kakium69> c/c++ = Alcohol. Everything is possible. Dangerous, but ubiquitous and embedded into the culture. And really not so bad if you have discipline and restraint.
2022-01-29T02:50:34 < kakium69> php = PCP. You’ll have side effects of hallucinations, delirium, and mania trying to figure out what the hell you’re looking at.

2022-01-29T12:39:39 < qyx> fenugrec: no problem at all, I have never seen anyone using those arrows. For modal windows or windows smaller than full screen there should be no scroll bar, it is a UI fail. For full screen windows, you can access the scollbar by moving cursor to the right without even looking
2022-01-29T12:39:51 < qyx> if done right of course
2022-01-29T12:40:14 < qyx> and they added a fine scroll functionality if you hold down the button longer when you start dragging
2022-01-29T12:41:09 < qyx> and for drop down list, you have a mouse wheel

2022-01-29T16:03:16 < fenugrec> qyx, with multiple monitors, sniping those few pixels wide scrollbar without falling into the next monitor, is awful. There was no reason to make it thinner
2022-01-29T16:04:35 < fenugrec> "windows smaller than fullscreen there should be no scroll bar" so what, everything fullscreen or bust ? You never resize a window to see what's underneath for reference ?

2022-01-29T18:59:04 < fenugrec> Lol, exactly
2022-01-29T18:59:43 < fenugrec> I'd rather have the scrollbar there all the time. Those listboxes, 99% of the time, need a scrollbar eventually anyway. It's not like hiding the bar gives me back any more real estate
2022-01-29T18:59:48 < karlp> I'm fine with getting rid of the arrows at the ends though, sure.
2022-01-29T18:59:56 < bitmask> ahh

2022-01-29T19:39:57 < karlp> fucking obtuse
2022-01-29T19:41:08 < BrainDamage> you can drop the auto and use casting to fit it directly
2022-01-29T19:41:26 < BrainDamage> you can cast to an abstract class
2022-01-29T19:42:47 < karlp> what, like "y = (ISleepHandler *) &HandleStop();

2022-01-29T19:43:20 < BrainDamage> reinterpret cast
2022-01-29T19:43:57 < BrainDamage> it tells the compiler to fuck off and say you're absolutely right
2022-01-29T19:44:56 < karlp> y = reinterpret_cast<ISleepHandler>(HandleStop()); is invalid too, "invalid cast from type ‘HandleStop’ to type ‘ISleepHandler’"
2022-01-29T19:45:19 < karlp> and reinterpre_cast<ISleepHandler*>(&HandleStop()) is the same rvalue address complaint?

2022-01-29T23:31:23 < karlp> meh, got LPSleep "workign" but it's still 500uA, should be more like 50 from the datahseet.
2022-01-29T23:31:33 < karlp> somethings not turned off I guess.
2022-01-29T23:35:53 < mawk> why do disabled interrupts wake up the mcu
2022-01-29T23:36:55 < karlp> probably have to be checked wehther they are enabled?
2022-01-29T23:38:29 < mawk> but waking up the mcu also wakes up the flash, no?
2022-01-29T23:38:41 < karlp> don't think so.
2022-01-29T23:41:50 < mawk> to go to lowest power mode you turn the flash off? and jump to sram before doing it
2022-01-29T23:49:11 < mawk> I guess not
2022-01-29T23:49:17 < mawk> the ram is off too
2022-01-29T23:51:34 < karlp> yeah, that's something it sas is optional
2022-01-29T23:51:49 < karlp> but I've gone to 100kHz MSI, flash even on is listed at only 8uA/Mhz in that mode,
2022-01-29T23:52:02 < karlp> so even with some periphs and flash, I should be ~50+~15-20.
2022-01-29T23:52:13 < karlp> that's still ~order of magnitude lower than what I'm seeing.

2022-01-30T00:04:00 < zyp> < mawk> why do disabled interrupts wake up the mcu
2022-01-30T00:04:17 < mawk> yes zyp it could just look up in the registers of the NVIC instead of waking up the mcu
2022-01-30T00:04:17 < zyp> because otherwise you could get deadlocked asleep
2022-01-30T00:04:31 < mawk> like if a concurrent interrupt arrives on the same time?
2022-01-30T00:04:35 < mawk> and is ignored
2022-01-30T00:04:57 < zyp> typical sleep code looks like this
2022-01-30T00:05:09 < zyp> if(!stuff_to_do()) { wfi(); }
2022-01-30T00:05:32 < mawk> yes
2022-01-30T00:06:04 < zyp> if an interrupt arrives and gives you stuff to do between the check and the wfi, you're missing it and going to sleep
2022-01-30T00:06:11 < mawk> now I know enough dutch to understand when people say "oh but that's actually a man" when they pass next to me Steffann 
2022-01-30T00:06:18 < Steffann> Lol
2022-01-30T00:06:19 < zyp> and if that was the only wakeup source, you're now stuck asleep
2022-01-30T00:06:35 < mawk> isn't wfi a no-op if there are still unacknowledged interrupts?
2022-01-30T00:06:52 < zyp> what's an unacknowledged interrupt?
2022-01-30T00:07:04 < mawk> well an interrupt you didn't read out
2022-01-30T00:07:11 < zyp> read out how?
2022-01-30T00:07:14 < mawk> from the relevant status register
2022-01-30T00:07:34 < zyp> you're on the right track, but wrong
2022-01-30T00:08:02 < zyp> remember that this is regular code
2022-01-30T00:08:54 < mawk> I mean pending, not unacknowledged, I guess
2022-01-30T00:09:04 < zyp> regular code can always be preempted by interrupts unless they are disabled, so you can still have an interrupt that arrives between the check and the wfi, that gets serviced and which ISR schedules more work
2022-01-30T00:09:22 < zyp> so by the time you get to the wfi, you got no pending interrupts left, it was already handled
2022-01-30T00:09:36 < mawk> ah yes
2022-01-30T00:09:53 < mawk> but that's bad programming
2022-01-30T00:09:56 < mawk> there should be a way to handle that case
2022-01-30T00:09:56 < zyp> to avoid this, you disable interrupts between the check and the wfi, which means that wfi will be executed with interrupts disabled
2022-01-30T00:10:25 < zyp> and for this reason, interrupts must be able to wake up the cpu again
2022-01-30T00:10:31 < zyp> even when disabled
2022-01-30T00:11:28 < mawk> so if you have an interrupt arrive at the wrong time, you need to wait until the next timer tick or whatever to wake you up
2022-01-30T00:11:37 < mawk> that sounds like a kludge
2022-01-30T00:11:49 < zyp> did you even read what I wrote?
2022-01-30T00:12:13 < mawk> yes
2022-01-30T00:12:30 < zyp> did you even comprehend what I wrote?
2022-01-30T00:12:36 < mawk> I hope
2022-01-30T00:12:55 < mawk> what wakes you up during the WFI if you handled the interrupt
2022-01-30T00:13:17 < zyp> possibly nothing, that's why it's a problem
2022-01-30T00:13:31 < zyp> and the solution is to turn off interrupts so it won't be handled before the wfi
2022-01-30T00:13:42 < mawk> so the wfi is a no-op when there are still pending interrupts
2022-01-30T00:13:47 < zyp> yes
2022-01-30T00:13:49 < mawk> why didn't you say yes when I said it
2022-01-30T00:13:51 < mawk> I thought it meant no
2022-01-30T00:14:02 < mawk> which is why I was confused
2022-01-30T00:14:08 < zyp> it's besides the point
2022-01-30T00:14:18 < mawk> how
2022-01-30T00:14:21 < mawk> it's fundamental to the point
2022-01-30T00:14:26 < zyp> the point is that for there to be a pending interrupt, they must be disabled
2022-01-30T00:14:47 < zyp> otherwise it'd be handled already by the time you get to the wfi

2022-01-30T00:15:57 < zyp> yeah
2022-01-30T00:16:01 < mawk> ah
2022-01-30T00:16:11 < mawk> yes that makes more sense calling it masked
2022-01-30T00:16:37 < zyp> the simplest way is cpsid d or whatever the instruction was to disable all interrupts
2022-01-30T00:17:11 < zyp> but the issue here is missing interrupts that can schedule tasks
2022-01-30T00:17:18 < mawk> yes
2022-01-30T00:17:39 < zyp> so if you really care about latency, you can leave other interrupts on and only disable the ones that'll fuck up your sleep
2022-01-30T00:18:05 < zyp> not entirely sure when that's useful, but it's possible :p

2022-01-30T00:19:32 < Steffann> They can claim it if its a mistake
2022-01-30T00:19:40 < Steffann> Perhaps a 13th month bonus?
2022-01-30T00:19:42 < mawk> they can't claim it from an empty account
2022-01-30T00:19:43 < mawk> yeah
2022-01-30T00:19:50 < mawk> but I thought vacation money was like in summer
2022-01-30T00:20:00 < mawk> maybe I get it twice a year
2022-01-30T00:20:09 < Steffann> Then you'll die from hunger next month 
2022-01-30T00:20:14 < mawk> :(
2022-01-30T00:20:36 < mawk> you're doing 6LoWPAN stuff karlp ?
2022-01-30T00:20:44 < Steffann> Nah, vacation money = ~1 month salary.
2022-01-30T00:20:50 < mawk> ah no that's bluetooth
2022-01-30T00:20:50 < karlp> zyp: well, I meant DFU, but you meant you managed to erase the secure flash right? 
2022-01-30T00:20:55 < mawk> 6lowpan is "stm32wk"
2022-01-30T00:21:08 < karlp> mawk: hardware can do 802.15.4 or ble.
2022-01-30T00:21:21 < mawk> stm3w-sk*
2022-01-30T00:21:22 < mawk> ah right
2022-01-30T00:21:23 < zyp> karlp, ah, yeah, I meant FUS
2022-01-30T00:21:41 < karlp> I'll be doing ble, but I'm currently working with just cpu1, trying to get sleep modes fifgured out
2022-01-30T00:22:03 < mawk> ah yes indeed
2022-01-30T00:22:03 < karlp> zyp: right, and no fus means you can't put any bins in cpu2, so you've got an L4 now...
2022-01-30T00:22:07 < zyp> yep
2022-01-30T00:22:18 < mawk> are you measuring current independently from the other cpu karlp ?
2022-01-30T00:22:35 -!- C-Man [~C-Man@78.31.190.82] has joined ##stm32
2022-01-30T00:22:37 < karlp> other cpu isn't booted, by all accounts of the docs adn the st code
2022-01-30T00:22:47 < mawk> I've never tried multi cpu yet
2022-01-30T00:22:48 < karlp> and that should be "double" not "order of magtnitude"
2022-01-30T00:22:49 < mawk> ah right
2022-01-30T00:22:54 < zyp> the prerelease RM documented how to unlock CPU2, and that process force-erases everything in a similar manner to disabling ROP
2022-01-30T00:23:02 < zyp> which I knew in advance
2022-01-30T00:23:13 < karlp> anyway, I've spent far too mcuh on this for "just try and finish this small bit to end the week on a high note"
2022-01-30T00:23:17 < mawk> is it locked because of certification?
2022-01-30T00:23:33 < mawk> nordic doesn't lock it like that
2022-01-30T00:23:34 < karlp> that's the story, yeah
2022-01-30T00:23:41 < karlp> nordic can't, you've only gone one cpu
2022-01-30T00:23:49 < zyp> the only issue is that release parts force-locks CPU2, so despite me managing to clear the option bit, it's still force set
2022-01-30T00:23:59 < zyp> nrf53 disagrees
2022-01-30T00:24:48 < karlp> zyp: also, c++ sucks so hard... :)
2022-01-30T00:25:07 < zyp> IMO having a locked second cpu seems like less of a hassle than having to integrate a «softdevice» blob into your firmware 
2022-01-30T00:25:16 < zyp> karlp, nah, you're just doing weird stuff
2022-01-30T00:25:47 < zyp> karlp, think about storage
2022-01-30T00:25:53 < Thorn> there're only 2 options in c++: the C way or weird stuff
2022-01-30T00:25:55 < mawk> they make an ANT dumb chip now
2022-01-30T00:26:00 < mawk> why are there so many different protocols
2022-01-30T00:26:38 < zyp> two different inherited classes can have different sizes, so you generally can't stick an inherited instance into space allocated for the parent instance
2022-01-30T00:26:50 < Steffann> ANT is old, nothing new... mawk
2022-01-30T00:27:11 < mawk> I mean nordic Steffann 
2022-01-30T00:27:18 < mawk> they make an ANT transceiver now
2022-01-30T00:27:24 < Steffann> Yes, they had it for years..
2022-01-30T00:27:28 < mawk> or maybe I never saw it before
2022-01-30T00:27:29 < mawk> 2010
2022-01-30T00:27:45 < mawk> they added it right and faked the date, and you're in on it
2022-01-30T00:28:23 < zyp> karlp, with heap allocation it's simple because you just allocate the appropriate size for the selected child class
2022-01-30T00:29:01 < zyp> without heap allocation you need to do something like a union
2022-01-30T00:31:58 < mawk> Steffann: french élégance: https://i.redd.it/a84n4wnoile81.jpg

2022-01-30T00:42:22 < karlp> zyp: I'm obviously not thinking about storage enough.  I know I didn't want new(), but what I wanted was java style Interface, where I could declare that a variable was going to hold an interface, 
2022-01-30T00:42:46 < karlp> and I still haven't really found anything nice that does that
2022-01-30T00:43:12 < karlp> I gave up an djust hardcoded shit to get _something_ done.
2022-01-30T00:44:21 < karlp> c++ just wasn't making a shitty end of week any better :)
2022-01-30T00:46:40 < Steffann> Now im hungry, mawk... 
2022-01-30T00:46:47 < mawk> lol
2022-01-30T00:47:22 < mawk> but java has new everywhere karlp

2022-01-30T00:47:28 < mawk> you just can't have it without that
2022-01-30T00:47:33 < mawk> unless you make an union like zyp said
2022-01-30T00:47:41 < mawk> or if you know in advance the maximum size of the child class
2022-01-30T00:47:49 < zyp> the java variable would be the equivalent of a pointer
2022-01-30T00:47:57 < mawk> which you usually don't, but you can put a good upper bound if you don't like economizing memory
2022-01-30T00:48:04 < zyp> it doesn't store the contents of the object itself, only a reference to it
2022-01-30T00:48:20 < karlp> well that's what my version does, with auto x = Class(), IHandler = &x;
2022-01-30T00:48:28 < karlp> and that worked on my desktop at least, just felt gross
2022-01-30T00:48:32 < karlp> made nice godbolt code
2022-01-30T00:48:42 < zyp> yeah
2022-01-30T00:48:51 < karlp> oh, I know why it went badly on my borad though.
2022-01-30T00:48:57 < zyp> question is just why
2022-01-30T00:49:00 < karlp> the actual implementtaiton the x class has gone out of scope
2022-01-30T00:49:06 < karlp> on godbolt it was still in scope...
2022-01-30T00:49:07 < zyp> yep
2022-01-30T00:49:27 < karlp> and on my desktop it was just stuffed in a single main, so all good
2022-01-30T00:50:26 < zyp> the laks usb class drivers are using polymorphic inheritance
2022-01-30T00:50:51 < zyp> the usb stack itself only knows about the driver interface
2022-01-30T00:50:52 < mawk> I guess if you do ChildClass x{}; Interface& i = x; and pass i around it's perfectly fine
2022-01-30T00:51:01 < mawk> but it's not really called an interface
2022-01-30T00:51:07 < mawk> an abstract base class maybe
2022-01-30T00:51:08 < karlp> as long s x stays in scop
2022-01-30T00:51:12 < mawk> yeah
2022-01-30T00:51:16 < karlp> interfaces can only be done in c++ by ABCs
2022-01-30T00:51:24 < karlp> what else would you call it?
2022-01-30T00:51:30 < mawk> abstract base class
2022-01-30T00:51:34 < zyp> so the intended pattern for those is to instance each driver as a global, and then pass pointers to each into the usb stack
2022-01-30T00:51:42 < mawk> I've only heard interface in java
2022-01-30T00:51:47 < zyp> that works, because globals doesn't go out of scope
2022-01-30T00:52:47 < zyp> ABC is pedantic, interface is understandable enough
2022-01-30T00:55:12 < mawk> interface must have only abstract methods
2022-01-30T00:55:15 < mawk> as I understand it
2022-01-30T00:56:20 < zyp> true

2022-01-31T00:06:49 < kakium69> yes
2022-01-31T00:07:27 < kakium69> my question is wrong..
2022-01-31T00:07:53 < kakium69> where is this type intance GPIOx... assigned?
2022-01-31T00:08:15 < zyp> platform definition
2022-01-31T00:08:26 < zyp> e.g. https://cgit.jvnv.net/laks/tree/platforms/stm32/f4.yaml?h=dev_v2#n37
2022-01-31T00:09:12 < kakium69> I saw this file yes
2022-01-31T00:09:23 < zyp> here's the stuff that goes in between: https://cgit.jvnv.net/laks/tree/gpio/SConscript?h=dev_v2
2022-01-31T00:11:59 < kakium69> that generates gpio.h?
2022-01-31T00:12:10 < zyp> yes
2022-01-31T00:13:22 < zyp> the big change in laks v2 is generation of all peripheral instances from platform definitions, instead of having to dick around manually updating headers with ifdefs and shit
2022-01-31T00:15:36 < zyp> makes it easy to later ingest platform definitions in other formats, e.g. a litex based fpga system
2022-01-31T00:16:12 < zyp> and generally easy to add a new mcu, because you don't need to go change stuff all over the place
2022-01-31T00:16:13 < kakium69> it's cool
2022-01-31T00:17:23 < zyp> the coolest part is that karlp likes it enough to go around and add a bunch of stuff, so laks v2 already got way more hardware support than v1, both in terms of supported parts and supported peripherals
2022-01-31T00:17:49 < kakium69> well.. it really makes it easy to add more hardware
2022-01-31T00:17:57 < kakium69> easier*
2022-01-31T00:18:48 < kakium69> lot less of mind numbing manual work to add everything
2022-01-31T00:19:13 < kakium69> instead of just name and key parameter

2022-01-31T00:21:45 < kakium69> STM32_GPIO_v?_t has no constructor?
2022-01-31T00:21:51 < zyp> part of the point of the yaml stuff is composing, i.e. going down a filter tree and merging fragments
2022-01-31T00:21:54 -!- tct [~tct@user/tct] has joined ##stm32
2022-01-31T00:22:04 < zyp> constructor is inherited
2022-01-31T00:22:27 < zyp> from here: https://cgit.jvnv.net/laks/tree/mmio/mmio.h?h=dev_v2
2022-01-31T00:22:58 < kakium69> yes
2022-01-31T00:24:22 < zyp> the main purpose of the mmio_ptr class is optimization
2022-01-31T00:26:01 < zyp> the issue is that the reinterpret_cast required to turn an integer address to a pointer is not considered constexpr, so it's not allowed in a constexpr constructor
2022-01-31T00:27:33 < zyp> storing the integer itself instead allows constexpr to optimize out the whole instance, and the ptr() function doing the cast when you actually use the pointer is then inlined and constant folded

2022-01-31T00:29:49 < kakium69> zyp: why would you have integer address in the first place?
2022-01-31T00:30:09 < zyp> because there's no such thing as a pointer literal

2022-01-31T00:32:00 < kakium69> (void*) == reinterpret_cast ?
2022-01-31T00:32:15 < BrainDamage> () is a reinterpreter cast
2022-01-31T00:32:16 < zyp> (void*)0x123; is equivalent to reinterpret_cast<void*>(0x123);
2022-01-31T00:32:24 < BrainDamage> just an alternate syntax for it
2022-01-31T00:32:33 < kakium69> whaa
2022-01-31T00:32:36 < kakium69> I learn today
2022-01-31T00:32:51 < zyp> C style casts can be static_cast too, I believe
2022-01-31T00:33:04 < Thorn> I remember situations when c-style cast worked but reinterpret_cast didn't
2022-01-31T00:33:07 < kakium69> why would you write such thing instead of ()
2022-01-31T00:33:13 < zyp> maybe dynamic as well, idk
2022-01-31T00:33:29 < BrainDamage> because then you're sure about what kind of casting you mean
2022-01-31T00:33:29 < Thorn> so it must be more powerful than all c++ casts combined
2022-01-31T00:33:30 < zyp> kakium69, to make it explicit which kind of cast you want
2022-01-31T00:34:23 < BrainDamage> it's like int can take different sizes in diff compilers, but int32t doesn't
2022-01-31T00:34:48 < BrainDamage> so by using interpret_cast you can be sure the compiler does what you want
2022-01-31T00:35:34 < kakium69> I never use int
2022-01-31T00:35:36 < PaulFertser> Probably it was "reinterpret_cast followed by const_cast" Thorn

2022-01-31T02:10:55 < karlp>  https://github.com/karlp/zypsnips/blob/master/lm1117.replacements.for.glory.md just with a typo...
2022-01-31T02:11:32 < karlp> qyx: I know it draws a lot, my problems seemt o hav ebeen related to how to make sure debug was actually off.
2022-01-31T02:11:42 < karlp> and also, how _much_ debug was taking.
2022-01-31T02:11:51 < karlp> on the l4 debug was apparently aroudn 1.38mA, 
2022-01-31T02:12:01 < karlp> eventhough reset consumption of l4 is only 400uA compared to ~700uA for wb.
2022-01-31T02:13:29 < karlp> zyp: the "filter tree" for l4 will need some work, like f3, there's some serious diversion within the family. that's a "later" problem right now though.

2022-01-31T13:02:31 < karlp> wb is still way too high though.  155uA in stop2, vs l4 at 1.7uA.

2022-01-31T19:09:18 < karlp> the cheapest you can possibly find...
2022-01-31T19:09:31 < karlp> unless it's actually a real user interface button..
2022-01-31T19:11:18 < benishor> and if it's a real user interface button?
2022-01-31T19:11:26 < benishor> I'm trying to do some single press, double press, long press detection on a cheap chinese push button
2022-01-31T19:11:34 < benishor> and bouncing kills me
2022-01-31T19:11:44 < benishor> I just put the saleae on it
2022-01-31T19:12:34 < karlp> the LA is goign to be different than the IOs... 
2022-01-31T19:12:43 < karlp> you want a scope really, but sure.
2022-01-31T19:13:05 < benishor> why is it going to be different than the IO?
2022-01-31T19:14:02 < karlp> because you're turning a noisy analog bouncy into Vthresholds from two different parts?
2022-01-31T19:14:21 < karlp> they'll be very similar, sure, just don't treat it as gospel
2022-01-31T19:20:12 < fenugrec> benishor, if you have just a few buttons, a pullup + RC filter will help with a lot of the bounce. I've been using simple manual software debouncing with one counter per switch, after N consecutive "iterations" (from a main loop) it updates the state. Probably better more efficient ways to do this, everybody probably has their own
2022-01-31T19:21:06 < englishman> hey zyp, the ioniq 5 has arrived here and it is indeed a very attractive buy. i would even consider trading into one when the warranty is up on the tesla. which model did you get and how do you like it now that you've had it for a while?
2022-01-31T19:22:02 < ventYl> fenugrec: what you described is even good enough for automotive, no reason why it shouldn't work
2022-01-31T19:22:41 < karlp> zyp doesnt' use button irqs either, didn't even have EXTI registers defined in laks, he says he just polls them...
2022-01-31T19:22:58 < fenugrec> ventYl, my implementation is actually inspired from some code I've seen in actualy ECU code : ))
2022-01-31T19:24:09 < fenugrec> I'd probably try something different if I was mass-producing a pr0-gam3r keyb0ard for low latency and stuff
2022-01-31T19:25:08 < ventYl> some better switch with well-defined switch position and signal as a starter
2022-01-31T19:28:07 < fenugrec> I wonder if they make boutique optical switches with a simple LED+sensor beam interrupt setup. 0 bounce guaranteed with proper hysteresis
2022-01-31T19:28:31 < englishman> i have a keyboard with magnetic switches
2022-01-31T19:28:36 < englishman> hall effect IC in each key
2022-01-31T19:28:46 < englishman> hysterisis is built in, there are adjustables too
2022-01-31T19:29:10 < englishman> i also used hall effect sensors as switches beneath an aluminum waterproof enclosure for deep-sea
2022-01-31T19:33:41 < fenugrec> nice. Does it go crazy if you bring something magnetic close to it
2022-01-31T19:34:04 < englishman> no the hysteresis works pretty well.
2022-01-31T19:34:30 < englishman> software rejects long and short pulses to 'debounce' and deals with double taps, etc.
2022-01-31T19:36:20 < englishman> apparently there are optical keyboards https://switchandclick.com/the-best-optical-keyboards/
2022-01-31T19:37:40 < fenugrec> there goes my idea for a $$$ startup

2022-01-31T20:18:06 < Xogium> er… you guys ever been given a zap by the low voltage end of a psu?
2022-01-31T20:18:28 < Xogium> I got a mini zap from the 12v side of the plug of my bluetooth speaker's psu
2022-01-31T20:19:26 < Xogium> I accidentally touched the metal side of the plug… but still, that's new to me, first time I get a zap like this
2022-01-31T20:20:20 < Xogium> it almost feels like ESD just more noticeable
2022-01-31T20:20:23 < Steffann> Must be static discharge ... 
2022-01-31T20:20:43 < Xogium> hmm
2022-01-31T20:21:02 < Xogium> I don't suppose wearing my wrist strap would help, would it ?
2022-01-31T20:21:09 < Steffann> If you do it again you get zapped again? :P
2022-01-31T20:21:23 < benishor> Steffann :D
2022-01-31T20:21:37 < Xogium> yeah actually I do
2022-01-31T20:21:46 < Xogium> this one felt like a needle jab
2022-01-31T20:23:04 < jpa-> some PSUs have low current 120VAC bias on the output due to lack of grounding & some filter capacitors
2022-01-31T20:23:27 < Xogium> but I can also feel the really weird sensation that is touching electricity ? I think, at least… It felt like there's a flating barrier of barely physically present things on the end of the plug
2022-01-31T20:23:28 < jpa-> not dangerous to people but feels annoying and sometimes it even breaks electronics
2022-01-31T20:24:19 < jpa-> sometimes if you turn the plug around in the outlet the problem disappears :)
2022-01-31T20:24:32 < Xogium> wah, weird
2022-01-31T20:24:56 < mawk> are there shooting ranges in NL Steffann ?
2022-01-31T20:24:56 < benishor> I can confirm I ran into that kind of a problem, fixed by turning the plug around
2022-01-31T20:25:06 < benishor> I don't have an explanation for it
2022-01-31T20:25:15 < Steffann> Yes mawk

2022-01-31T20:27:06 < Xogium> so oly solution to get rid of that os to turn the psu around in the plug ?
2022-01-31T20:27:27 < jpa-> Xogium: you are lucky if that helps, sometimes the only solution is to get a grounded power supply
2022-01-31T20:27:52 < jpa-> IMO it is laziness on part of the PSU designers, there are ways to pass EMC tests without zapping the users
2022-01-31T20:27:56 < Xogium> yeah I think this one is definitely not grounded
2022-01-31T20:28:17 < Xogium> it just shocked me, pun intended. First time it happens in like 2 years
2022-01-31T20:29:43 < Xogium> well at least I hope I don't kill my bluetooth speaker lol
2022-01-31T20:31:27 < Xogium> too bad it wouldn't get grounded with my esd mat ;)
2022-01-31T20:33:44 < Xogium> well, now that's…
2022-01-31T20:33:59 < Xogium> it seems to have entirely discharged whatever it was in my fingers

2022-01-31T22:51:10 < kakium69> zyp: why you want to constexpr mmio_ptr =

2022-01-31T22:51:50 < kakium69> that is why you need to use integer address instead of pointer
2022-01-31T22:52:24 < kakium69> it now boils down to that I dont undestand constexpr
2022-01-31T22:53:29 < zyp> so that it'll properly constant fold, and not actually emit a pointer
2022-01-31T22:54:55 < zyp> englishman, I got the RWD, still pretty happy with it
2022-01-31T22:55:46 < zyp> offered models seems to differ between countries so I'm not sure how it compares to what's available over there
2022-01-31T22:56:30 < ventYl> as usual
2022-01-31T22:56:51 < kakium69> what will constant fold zyp?
2022-01-31T22:56:52 < zyp> I think we only get the option of RWD/AWD, 19" or 20" rims and with or without vision roof
2022-01-31T22:57:39 < zyp> kakium69, accessing registers
2022-01-31T22:58:40 < catphish> i did some 3d modelling today :) https://i.imgur.com/3pG8ogu.jpg
2022-01-31T22:59:11 < englishman> well in beaverbux, it's $45k for RWD 58 kWh, add $3k for AWD, add $8k for 77 kWh. on the highest end one, there is a tech package for $5k that adds huge wheels (a downgrade imo), power folding mirrors, rain sensing wipers, and other stuff that is standard on other cars which is kind of annoying.
2022-01-31T22:59:37 < zyp> ah, we only got the 72 kWh variant here
2022-01-31T23:00:00 < ventYl> catphish: case study on topic "what a cardboard can provide in terms of design
2022-01-31T23:00:01 < ventYl> " ?
2022-01-31T23:00:17 < zyp> heard rumors about 77 coming later, but the difference doesn't sound worth waiting for
2022-01-31T23:00:27 < englishman> probably isn't
2022-01-31T23:00:52 < zyp> huge wheels as in 20"?
2022-01-31T23:01:03 < englishman> hmm the description seems to indicate that power windows are optional, so this might be just a poor website as i suspect
2022-01-31T23:01:05 < englishman> yes
2022-01-31T23:01:08 < zyp> they're a separate option here, but required if you want vision roof
2022-01-31T23:01:17 < catphish> ventYl: this is actually cheap board of some kind, seems half way between cardboard and mdf
2022-01-31T23:01:18 < englishman> i am definitely not buying a sedan with 20" wheels
2022-01-31T23:01:36 < englishman> tires cost almost 250% vs. 18"

2022-01-31T23:01:50 < zyp> wastes range as well
2022-01-31T23:02:13 < catphish> weight of wheels is pretty negligable
2022-01-31T23:03:57 < ventYl> with EV it might not be as much of a concern, but with ICE, heavier wheels are much of a concern
2022-01-31T23:04:05 < ventYl> as they are not only moving, but also rotating
2022-01-31T23:04:53 < ventYl> power windows as option? I thought, that window cranks are so rare, that they are incredibly expensive to be manufactured
2022-01-31T23:05:20 < englishman> huh, on the top trim model power windows are actually optional yeah
2022-01-31T23:05:22 < englishman> weird
2022-01-31T23:05:25 < englishman> lower trims have it standard
2022-01-31T23:05:48 < catphish> ventYl: believe it or not, the wheels rotate on EVs too
2022-01-31T23:05:53 < englishman> this must be some dealership fuckery
2022-01-31T23:06:07 < englishman> wow you're being a huge dick
2022-01-31T23:06:12 < englishman> why would anyone want to reply to you?
2022-01-31T23:06:23 < ventYl> catphish: but EVs can recouperate
2022-01-31T23:07:03 < ventYl> so you can get back portion of energy invested in making them rotate. with ICE, energy used to spin the wheels is a net loss
2022-01-31T23:07:07 < englishman> zyp, is the infotainment usable? i am wondering if manufacturers are doing a competent job of ui/ux as cars move to touchscreen interfaces
2022-01-31T23:07:26 < catphish> ventYl: ultimately it just adds to the kinetic energy, but yes, in an ICE car, that means more loss under braking
2022-01-31T23:08:00 < catphish> englishman: who has a huge dick?
2022-01-31T23:08:13 < mawk> I can check for you catphish

2022-01-31T23:17:52 < kakium69> zyp: what does constructor have to do with accessing registers?
2022-01-31T23:22:19 < ventYl> catphish: yes and no. while you have to accelerate the car only for linear motion, with wheels, you have to accelerate them for linear motion *and* also spin them

2022-01-31T23:24:41 < catphish> ventYl: you're right, but the energy that goes into spinning the wheels is generally not wasted, it's just stored as kinetic energy, however, heavier wheels are clearly less efficient when it comes to braking
2022-01-31T23:24:58 < ventYl> empiric racing wisdom says, that removing one kg from wheel / tyre / brake rotor / hub has the same overal efect as removing 4kg of sprung weight from the rest of the car
2022-01-31T23:25:27 < ventYl> it is stored, but in case of ICE you have almost zero chance to get it back
2022-01-31T23:28:39 < BrainDamage> heavier wheels means also having a more difficult time steering, altough I guess power steering makes that moot
2022-01-31T23:29:16 < BrainDamage> there might be some non trivial mechanics with windup tho
2022-01-31T23:29:34 < catphish> ventYl: for racing that makes a lot of sense, it makes accelerating and braking more expensive
2022-01-31T23:30:16 < catphish> i suppose the same argument can be made for any weight, it's only inefficient when you're trying to change its velocity

2022-01-31T23:45:53 < kakium69> my car makes funny sound when I drop clutch

2022-01-31T23:47:05 < catphish> is it an awesome tyre screeching noise?
2022-01-31T23:48:09 < kakium69> no it's interesting clutch sound
2022-01-31T23:48:39 < ventYl> why do you drop clutch at full throttle?
2022-01-31T23:48:40 < BrainDamage> the sound of syncros being polished to a shine?
2022-01-31T23:48:56 < kakium69> or is it synchros
2022-01-31T23:49:25 < kakium69> anyways wheel speed goes up and engine speed goes down
2022-01-31T23:49:33 < kakium69> but not instantly
2022-01-31T23:50:00 < Xogium> this error message is one of the funniest I've ever seen
2022-01-31T23:50:04 < ventYl> any funky smell?
2022-01-31T23:50:06 < Xogium> try and beat that
2022-01-31T23:50:07 < Xogium> Could not load: libcogplatform-wl.so (possible cause: Success).
2022-01-31T23:50:11 < kakium69> ventYl: nope
2022-01-31T23:51:11 < kakium69> I don't think 0.5-1sec clutch slip does anything
2022-01-31T23:51:21 < ventYl> Xogium: that's unfortunate. someone performed a call, which wiped errno before actually calling perror
2022-01-31T23:51:58 < Xogium> ventYl: like the famous error where windows told you 'keyboard not responding. Press any key to continue'
2022-01-31T23:52:01 < Xogium> ?
2022-01-31T23:54:55 < ventYl> Xogium: no, dlopen() or something was supposed to set errno, but the application called something else meanwhile, effectively wiping stored error code. then later, calling perror() returned "Success" as there was no error written
2022-01-31T23:55:00 < ventYl> it already happened to me before
2022-01-31T23:55:43 < Xogium> damn yeah that's a bit on the dumb unfortunate side
2022-01-31T23:56:03 < ventYl> it's easy to place something, which touches errno in between
2022-01-31T23:56:06 < Xogium> I suspect it would be error -2 here, but yeah… not cool
2022-01-31T23:56:18 < ventYl> IIRC, errno also is not thread safe, or at least wasn't until TLS
2022-01-31T23:56:34 < karlp> ok.. set pin to AF, not just set AF number, that's a start...
2022-01-31T23:57:23 < karlp> and, classic: "auto pb6 = GPIOA[6];
