I weren't aware UDS is a separate thing, looks like what I've been looking at is actually UDS PIDs 2021-11-02T09:55:18 < ventYl> UDS and OBD are quite similar, in fact from function POV almost identical protocols 2021-11-02T09:55:46 < ventYl> the difference is that OBD IDs are hardcoded by OBD standard for most part while UDS is mostly defined by OEM 2021-11-02T09:56:15 < zyp> makes sense

Since its mem2mem, DMA runs unrestricted at speed. I wonder if this valid/loses GPIO cycles tho. I dont have hispeed multichannel bus analyzer to see. Does someone haves idea if this combo fully valid? 2021-11-02T15:00:42 < zyp> why would you run it mem2mem? generally when you DMA to GPIO, you use a timer to generate DMA requests 2021-11-02T15:00:58 < zyp> so that you can run it at a given rate 2021-11-02T15:01:03 < System_Error> To run at fastest possible/available speed. 2021-11-02T15:01:14 < zyp> what would that be useful for? 2021-11-02T15:02:31 < System_Error> Strange stuff, from fast (but somewhat imperfect) portwide PWM to "packet crafting" if destination smth like i8080/86xx bus (e.g. LCD module) 2021-11-02T15:03:09 < zyp> I believe flow control would ensure that every write actually completes, so you shouldn't lose anything, but as you say the IO buffers might not keep up 2021-11-02T15:03:20 < System_Error> E.g. LCD could be able to swallow more or less sizable speed, as long as bus timings not violated. 2021-11-02T15:04:09 < zyp> if you've got a memory mapped LCD, hook it to FSMC/FMC, not DMA/GPIO 2021-11-02T15:04:43 < System_Error> No, controller-based with own mem, and FSMC monsters are a bit too huge for my taste. 2021-11-02T15:05:20 < zyp> that's what a memory mapped LCD is 2021-11-02T15:06:09 < zyp> sounds like a waste of time either way 2021-11-02T15:07:22 < System_Error> there're lcds using 8080 or 68xx bus 8 or 16 bit (also eventually SPI 8/9), and they have onboard VRAM and controller. 2021-11-02T15:08:06 < zyp> yes, they'll hook up to FMC 2021-11-02T15:08:25 < zyp> also, if you're not doing any access delays, writing a DMA buffer takes just as much CPU cycles as just writing GPIO directly 2021-11-02T15:08:45 < System_Error> so I think I can sacrifice more or less one port to craft 8-bit bus with all signals, etc. No, I do NOT want to deal with huge FSMC stuff and memmapped controllers. 2021-11-02T15:10:14 < System_Error> I'm curious to "craft bus" using GPIO. FSMC only exists in hi-end chips, they're pricey and use hard to route packages. 2021-11-02T15:10:29 < zyp> uh 2021-11-02T15:10:35 < zyp> like qfp64? 2021-11-02T15:11:14 < System_Error> valid, BUT dma is: make packet, start sending, forget about it, get IRQ when done. GPIO write by SW: get stuck for whole xfer time... 2021-11-02T15:12:05 < System_Error> like qfp64? <- Ye, why not? 8080 bus needs like 8 data lanes+few signals. Apparently fits one GPIO. 2021-11-02T15:12:23 < zyp> what's the difference between «stuck for whole xfer time» and «stuck for whole make packet time»? 2021-11-02T15:12:50 < System_Error> DMA not makes core completely stuck, DS says it releases bus for one cycle. 2021-11-02T15:13:01 < System_Error> So it would be background xfer XD 2021-11-02T15:13:03 < zyp> you're missing my point 2021-11-02T15:14:03 < zyp> if you're gonna write say 200 gpio state changes, you can either write 200 entries to a buffer and point DMA at it, or you can write BSRR directly 200 times 2021-11-02T15:14:31 < zyp> either way, the CPU needs to actually do the 200 writes 2021-11-02T15:15:35 < zyp> DMA is useful to avoid needing to busywait between each write, letting the CPU write the whole buffer in a burst and then have DMA do the busywaiting 2021-11-02T15:16:42 < zyp> but you suggest just writing BSRR flat out, in which case the CPU could just do that in about the same time it'd take to prepare the buffer 2021-11-02T15:16:52 < zyp> and in that case, DMA wouldn't save anything 2021-11-02T15:17:44 < ventYl> unless 8080 bus is using different clk than CPU itself 2021-11-02T15:18:12 < System_Error> Ahh, I think I got idea. But, wait, flash can also be source of DMA... 2021-11-02T15:18:14 < System_Error> When I tested if it can work at all, I used flash constant. Thus no dma buffer setup at all. Ye, it inflates data size tho. 2021-11-02T15:18:23 < zyp> yes, but System_Error already said they wanted to go full speed 2021-11-02T15:18:39 -!- catphish [~charlie@user/catphish] has joined ##stm32 2021-11-02T15:18:41 < zyp> yeah, you can DMA from static buffers 2021-11-02T15:18:46 < catphish> morning! 2021-11-02T15:18:52 < zyp> but how useful is that? 2021-11-02T15:18:58 < ventYl> catphish: you vanished ignoring my answer 2021-11-02T15:19:09 < ventYl> s/ignoring/not waiting/ 2021-11-02T15:19:30 < catphish> ventYl: sorry, i actually read the backlog and realised you'd already answered it 2021-11-02T15:19:37 < catphish> but didn't mean to vanish 2021-11-02T15:19:51 < catphish> any other ideas welcome! 2021-11-02T15:20:11 < catphish> it's not an area i've really looked at yet, it'll definitely be an aftertought, but an interesting one 2021-11-02T15:20:13 < ventYl> catphish: the thing is, that UDS is usually the payload of "OEM-specific" extension to OBD 2021-11-02T15:20:26 < ventYl> so it is often falsely treated as if it was OBD 2021-11-02T15:20:31 < catphish> ah okay 2021-11-02T15:20:50 < catphish> so i will almost definitely expose the canbus of my car on a port somewhere 2021-11-02T15:20:58 < ventYl> those files from EVs zyp shown me look a lot that someone is using OBD II as a carrier for UDS services 2021-11-02T15:21:01 < catphish> but beyond that, i hadn't given any thought to how it might be used 2021-11-02T15:21:38 < ventYl> well, typically, central gateway module of car has one CAN bus exposed to OBD (diagnostic) connector 2021-11-02T15:22:01 < ventYl> central gateway then runs forwarding service, which forwards CAN frames around based on their CAN IDs 2021-11-02T15:22:20 < System_Error> Or I can point DMA to flash with 200 precoded changes... 2021-11-02T15:22:45 < catphish> ventYl: that makes sense, though i'll probably only bother with one bus 2021-11-02T15:22:59 < ventYl> each ECU then runs it's own diagnostic server, which responds to diagnostic requests 2021-11-02T15:23:26 < ventYl> catphish: yeah, I'd isolate propulsion CAN bus only if there were any time-sensitive data on it 2021-11-02T15:24:59 < catphish> i don't think i will be using CAN for anything critical, if i do, i'll definitely use a dedicated bus, but no actual vehicle control will use CAN 2021-11-02T15:25:42 < ventYl> great, then you can expose CAN directly on OBDII socket, so you'll be compatible with stuff like ELM327-based readers 2021-11-02T15:25:50 < System_Error> but how useful is that? <- at least LCD init would be ok. Maybe some fixed pics, etc. 2021-11-02T15:26:20 < ventYl> newer ELMs have CAN passthrough feature, so you can use them to a) sniff CAN traffic b) inject CAN traffic c) implement any protocol on top of CAN 2021-11-02T15:26:38 < ventYl> a) and b) are useful for debugging purposes 2021-11-02T15:26:59 < ventYl> altough not in real production car, for most cases 2021-11-02T15:27:08 < System_Error> Also: SRAM accepts 32 bit so if using GPIO data reg as DMA dst, SRAM can be 2x faster to write, no? 2021-11-02T15:27:50 < zyp> BSRR is also 32 bits wide 2021-11-02T15:28:09 < System_Error> can be also port data reg I guess. 2021-11-02T15:28:16 < catphish> ventYl: being compatible with ELM327 surely also requires implementing higher level protocols 2021-11-02T15:28:30 < catphish> oh, you just answered that 2021-11-02T15:28:34 < ventYl> catphish: not, it doesn't ^^ 2021-11-02T15:28:38 < System_Error> that would only want 16 bit, though loses option to mask out some "unused/dont touch" pins 2021-11-02T15:28:56 < catphish> right now i just use an arduino for logging / injecting things 2021-11-02T15:30:08 < ventYl> catphish: well, realistically, there is probably no real advantage of using UDS over as both can do roughly the same. the only advantage of UDS is standardization. and the fact, that it is track-proven 2021-11-02T15:30:33 < ventYl> proprietary nature of UDS payload means, that you won't be able to use any generic tool for diagnostics purposes 2021-11-02T15:31:13 < catphish> ventYl: i think the main reason i'd do this is to allow generic ODB loggers to be plugged in and read things like speed and tempertures 2021-11-02T15:31:39 < catphish> but i could go further and expose my tuning setup over it using a proprietary protocol 2021-11-02T15:31:56 < ventYl> I think that generic OBD loggers use OBD protocol (UDS sibling) using standardized UDS PIDs 2021-11-02T15:32:17 < catphish> this is what i'm working on today, my CAN<->Battery interface https://i.imgur.com/YPEbpbX.jpg 2021-11-02T15:32:32 < catphish> arduino on the right for testing 2021-11-02T15:32:35 < ventYl> but you can run OBD for generic stuff and UDS for proprietary tuning stuff on same controller 2021-11-02T15:32:48 < catphish> ventYl: yeah that makes sense 2021-11-02T15:33:14 < ventYl> I run UDS on my solar water heater for flashing and data retrieval purposes 2021-11-02T15:33:22 < ventYl> pro of UDS is, that you can make it really small 2021-11-02T15:33:47 < catphish> this talks to batteries and reports cell voltages over CAN, a BMS will use this to decide when to initiate balancing, and some other stuff probably 2021-11-02T15:34:52 -!- The_Jag [~The_Jag@host-79-52-47-230.retail.telecomitalia.it] has quit [Read error: Connection reset by peer] 2021-11-02T15:35:43 < ventYl> I hope you wan't how many volts exactly 12 volts is :) 2021-11-02T15:35:55 -!- The_Jag [~The_Jag@host-79-52-47-230.retail.telecomitalia.it] has joined ##stm32 2021-11-02T15:36:08 < ventYl> my ex-company tester's usual answer based on the state of BMS software was: whatever value between 9 and 16 volts 2021-11-02T15:36:57 < catphish> pardon?

useful arbitration? 2021-11-03T10:21:03 < catphish> i did consider using different CAN IDs, but i'd need to allocate 256 just for the voltages! 2021-11-03T10:21:19 < catphish> 512, assuming 2 devices on the bus 2021-11-03T10:21:34 < catphish> and that's a LOT of the namespace, before even thinking about adding temperatures 2021-11-03T10:21:37 < ventYl> no you don't you can pack multiple voltages into one message 2021-11-03T10:22:30 < ventYl> the thing is that you actually have two constraints, one is namespace size, another is the bandwidth of CAN 2021-11-03T10:22:56 < ventYl> your format wastes like 50% of the bandwidth available to transmit useless information 2021-11-03T10:24:04 < catphish> i could pack 4 voltages per frame 2021-11-03T10:24:21 < catphish> then i'd need 16 * 4 CAN addresses to cover all voltages 2021-11-03T10:24:25 < catphish> it's the most efficient 2021-11-03T10:25:38 < catphish> or i could pack 2 voltages per frame and still have 4 bytes space for an

frankly, it's irritating that CAN frames are so small 2021-11-03T10:26:16 < ventYl> there would still be some free space, which can be used by e.g. communication error counter 2021-11-03T10:26:31 -!-

one transmitter of message with unique CAN ID, no two transmitters shall *ever* transmit messages having same CAN ID 2021-11-03T10:37:23 < catphish> yes, that part is obviously needed to avoid bus conflicts 2021-11-03T10:37:32 < catphish> hence my jumper changing CAN ID 2021-11-03T10:38:23 < catphish> it's also why sending "commands" on a CAN bus kinda sucks, because only one device is allowed

think of it as a signal 2021-11-03T10:42:47 < ventYl> the way how typical automotive CAN is organized is, that various CAN messages transmit various groups of signals 2021-11-03T10:43:00 < ventYl> each group is transmitted periodically carrying samples of signals 2021-11-03T10:43:10 < ventYl> it is digital equivalent of wiring harness 2021-11-03T10:43:48 < catphish> makes sense 2021-11-03T10:44:24 < ventYl> like, there will be CAN ID reserved for exterior lighting and it will contain signals for left turn signal, right turn signal, left standing light, right standing light, taillight enabled, dimmed beam and high beam 2021-11-03T10:44:40 < qyx> who the fuck told me that in can 2.0 the transmitter monitors rx/tx during the whole frame 2021-11-03T10:45:09 < qyx> the specs states arbitration is done using id and remote bits 2021-11-03T10:45:12 < ventYl> most probably also some other bullshit, which needs same sample rate as that lighting information would only occupy less than one byte, which is a waste of bandwidth 2021-11-03T10:45:37 < catphish> qyx: indeed 2021-11-03T10:46:19 < ventYl> then, those messages have fixed broadcast period and offset related to other messages on bus 2021-11-03T10:46:36 < ventYl> period is critical, because it allows to interpolate analog values 2021-11-03T10:47:02 < ventYl> and if message is off it's timing or is missing completely, it triggers bus error 2021-11-03T10:47:14 < ventYl> and pushes failsafe values instead 2021-11-03T10:47:47 < qyx> but still, it is possible to send two messages with the same id 2021-11-03T10:48:14 < ventYl> well, it is 2021-11-03T10:48:19 < ventYl> but you shall not do that 2021-11-03T10:49:18 < qyx> I think we are missing something here 2021-11-03T10:49:32 < ventYl> no, we

2021-11-06T23:37:58 < kakium69> c55 2021-11-06T23:38:32 < catphish> if so, yeah, they misconfigured things so that the throttle calls for more torque than the allowed current limit (or current the battery can actually provide) 2021-11-06T23:39:07 < catphish> i've seen the same thing in both vehicles i'm tuning, but it's a simple fix to reduce the max torque on the throttle 2021-11-06T23:40:05 < catphish> both the gs450h and the tesla drives i'm working with do the same thing (performance get weird if you request more torque than current allows for) 2021-11-06T23:40:06 < kakium69> I think you need to monitor the voltage 2021-11-06T23:40:36 < catphish> well, it could be voltage sag, or it could be a software current limit 2021-11-06T23:40:44 < catphish> both will cause the same behaviour 2021-11-06T23:41:17 < kakium69> does those inverters have battery side current monitor? 2021-11-06T23:42:08 < catphish> the tesla only has current monitors on the AC lines, it estimates DC current, and it has configurable limits on both 2021-11-06T23:42:31 < kakium69> interestings 2021-11-06T23:42:37 < catphish> the gs450h, i know less about its internals, but it also has a configurable DC current limit 2021-11-06T23:42:50 < kakium69> it does maths to know approx battery amps 2021-11-06T23:43:19 < catphish> yes 2021-11-06T23:43:31 < kakium69> leaf inverter doesn't 2021-11-06T23:43:56 < catphish> it has its own internal limits though 2021-11-06T23:43:58 < kakium69> it's just how much torque you want and AC current limits are hardcoded 2021-11-06T23:44:08 < kakium69> no DC current limits 2021-11-06T23:44:19 < kakium69> or maybe there is 2021-11-06T23:44:30 < catphish> i'm not certain, i know you request a torque 2021-11-06T23:44:43 < catphish> and at its simplest, max torque = max current 2021-11-06T23:44:51 < catphish> but there *may* be other limits internally 2021-11-06T23:45:38 < catphish> though there shouldn't need to be, if it's designed to work with a matched battery 2021-11-06T23:45:39 < catphish> so maybe not 2021-11-06T23:46:05 < catphish> if so, maybe he's just running it with a battery too small for its OEM max torque current 2021-11-06T23:50:57 < kakium69> I think it never was his intention to make it about performance 2021-11-06T23:51:15 < kakium69> it's his daily all arounder 2021-11-06T23:56:53 < catphish> i suspect i'll be a bit obsessive about correct tuning --- Day changed Sun Nov 07 2021 2021-11-07T00:05:11 < kakium69> it's all about correct tuning 2021-11-07T00:05:27 < kakium69> for driver 2021-11-07T00:22:34 -!- mouseghost [~draco@user/mouseghost] has quit [Quit: mew wew] 2021-11-07T00:39:01 < catphish> well some tuning is just wrong :) 2021-11-07T00:39:23 < catphish> more throttle should mean same or more torque i all circumstances 2021-11-07T00:39:26 < catphish> *in all 2021-11-07T00:40:15 < catphish> but this may not be simple if you're commanding torque without the necessary feedback 2021-11-07T00:44:43 < kakium69> more throttle should mean relativelly more torque 2021-11-07T00:44:53 < kakium69> not absolutelly more torque necessary 2021-11-07T00:45:46 < kakium69> throttle map could be scaled per predicted or measured battery power capacity 2021-11-07T00:46:29 < kakium69> like in any production EV 2021-11-07T00:48:52 < kakium69> also battery temperature could scale down throttle map 2021-11-07T00:49:41 < kakium69> with threshold steps or with exp curve 2021-11-07T01:02:06 < catphish> my statement was simply that more throttle should never result in less torque than less throttle 2021-11-07T01:02:51 < catphish> though interestingly enough, the same thing occurs in non-electronic internal combustion engines 2021-11-07T01:03:37 < catphish> if fuel flow is insufficient, excessive throttle will lean the mix and stall the engine 2021-11-07T01:03:54 < catphish> almost exactly the same cause 2021-11-07T01:37:59 -!- IanW_ [~IceChat9@arcanum.force9.co.uk] has quit [Quit: Bye] 2021-11-07T02:22:25 -!- xnand [~ircbridge@2a00:1028:83a2:71a6:21f:11ff:fe02:1846] has quit [Remote host closed the connection] 2021-11-07T02:22:41 -!- xnand [~ircbridge@2a00:1028:83a2:71a6:21f:11ff:fe02:1846] has joined ##stm32 2021-11-07T02:47:15 -!- ferdna [~ferdna@user/ferdna] has quit [Quit: Leaving] 2021-11-07T03:19:37 -!- specing_ [~specing@user/specing] has joined ##stm32 2021-11-07T03:19:37 -!- specing [~specing@user/specing] has quit [Killed (NickServ (GHOST command used by specing_))] 2021-11-07T03:19:39 -!- vit [~vit@chello085216193138.chello.sk] has quit [Ping timeout: 256 seconds] 2021-11-07T03:21:23 -!- specing_ is now known as specing 2021-11-07T03:45:09 -!- boB_K7IQ [~boB_K7IQ@c-24-19-3-104.hsd1.wa.comcast.net] has quit [Ping timeout: 256 seconds] 2021-11-07T03:46:01 -!- boB_K7IQ [~boB_K7IQ@c-24-19-3-104.hsd1.wa.comcast.net] has joined ##stm32 2021-11-07T03:53:05 -!- boB_K7IQ [~boB_K7IQ@c-24-19-3-104.hsd1.wa.comcast.net] has quit [Ping timeout: 256 seconds] 2021-11-07T03:53:25 -!- boB_K7IQ [~boB_K7IQ@c-24-19-3-104.hsd1.wa.comcast.net] has joined ##stm32 2021-11-07T03:55:55 -!- oz4ga [~tim@93.90.4.233] has quit [Ping timeout: 256 seconds] 2021-11-07T04:03:51 -!- Mangy_Dog [Mange@user/mangy-dog/x-7397214] has quit [Ping timeout: 256 seconds] 2021-11-07T04:06:08 -!- oz4ga [~tim@93.90.4.233] has joined ##stm32 2021-11-07T04:25:57 -!- upgrdman [~upgrdman@047-034-183-147.res.spectrum.com] has joined ##stm32 2021-11-07T04:26:17 < upgrdman> arm pros: anyone know if the pi 4 processor supports SVE?

slow but simple and safe, i tried temperature based control, but didn't like the temperature swings, figured that might cause stress to the components 2021-11-08T00:30:28 < kakium69> true 2021-11-08T00:30:49 < catphish> kakium69: so, basically, i bled one cell for about 3 hours 2021-11-08T00:31:13 < catphish> and now i'm using my automated code to re-balance (ie bleed all the others to match) 2021-11-08T00:31:37 < catphish> but i didn't know when i started that it would be so slow, so it's going to take 15 x 3 hours :) 2021-11-08T00:31:38 < kakium69> one cell at time? 2021-11-08T00:31:53 < catphish> kakium69: yes and no 2021-11-08T00:32:10 < catphish> it always discharges the cell with the highest voltage only 2021-11-08T00:32:16 < kakium69> what if 2021-11-08T00:32:21 < kakium69> matching voltages 2021-11-08T00:32:26 < catphish> so once 2 are the same it round robins them 2021-11-08T00:32:42 < kakium69> ok 2021-11-08T00:32:45 < catphish> the

a deep red position lol 2021-11-08T23:45:10 < Steffanx> Lol jadew 2021-11-08T23:52:21 < kakium69> jadew: before or after you heard musk is going to cash in? 2021-11-08T23:52:48 < jadew> kakium69, I heard yesterday and was planning to short it early in the morning 2021-11-08T23:53:04 < jadew> I placed my order and it didn't go thru until it started rising again 2021-11-08T23:53:10 < kakium69> did you catch early train? 2021-11-08T23:53:25 < jadew> basically the broker fucked me over 2021-11-08T23:53:49 < kakium69> yes 2021-11-08T23:54:22 < kakium69> but doesn't those options have like a timespan? 2021-11-08T23:54:35 < jadew> it was a market order 2021-11-08T23:54:55 < jadew> I placed it at the open, but it was executed whenever 2021-11-08T23:55:46 < kakium69> ah 2021-11-08T23:55:48 < jadew> I think it's safe to say that retail investors cannot win on transient changes, because they just won't execute your orders until their orders are done 2021-11-08T23:55:58 < jadew> whoever "they" is 2021-11-08T23:56:40 < jadew> you can only play fortune teller and try to guess what will happen in the long run 2021-11-08T23:56:55 < jadew> but if there's a clear momentum change, you can't get in 2021-11-08T23:57:07 < kakium69> you gave your money to "they" 2021-11-08T23:57:15 < jadew> it looks like it, yeah 2021-11-08T23:59:04 < jadew> it's still baffling me, because I would have expected it to tank 2021-11-08T23:59:38 < kakium69> when exactly? 2021-11-08T23:59:41 < jadew> his brother sold on Friday I think 2021-11-08T23:59:53 < jadew> other directors at tesla sold in the past couple of weeks --- Day changed Tue Nov 09 2021 2021-11-09T00:00:17 < jadew> and now Musk pretty much announces that he's going to sell %10 of his position 2021-11-09T00:00:33 < kakium69> better have some cash 2021-11-09T00:00:44 < jadew> if this is not a good enough indicator that it's overpriced, I don't know what is 2021-11-09T00:00:49 < jadew> people still bought the dip... 2021-11-09T00:01:08 < kakium69> it's fantanstically overpriced 2021-11-09T00:01:37 < jadew> yeah, and I'm not sure exactly what the logic behind it is 2021-11-09T00:02:26 < jadew> are they all retards and don't know what they're doing, or are they smart and playing to be idiots to one another, in order to attract more idiots so they can cash out before everone else? 2021-11-09T00:02:56 < kakium69> something like that 2021-11-09T00:03:36 < jadew> it's very difficult to make sense of it, and then there's the question of what is the strategy of the funds? 2021-11-09T00:03:52 < jadew> what are they basing their in and outs on? 2021-11-09T00:04:14 < jadew> the stock price is divorced from fundamentals, so they must be using something else 2021-11-09T00:04:32 < Steffanx> Now have a look at buttcoin 2021-11-09T00:04:33 < jadew> memetics or some shit - I bet they have at least one or two reference books on this already 2021-11-09T00:05:15 < jadew> Steffanx, yeah... it's trading a lot like that 2021-11-09T00:05:31 < jadew> but 2021-11-09T00:05:39 < jadew> but Tesla does have a fundamental value 2021-11-09T00:08:40 < jadew> the problem with my reasoning is that aside from a couple of trades at the beginning, when I didn't know what I was doing, all other moves I've done on the market seemed to be timed perfectly with the worst time to make those particular moves 2021-11-09T00:09:18 < jadew> if I bought a stock, it was like putting a marker on the chart for the highest price of the day/week 2021-11-09T00:09:27 < jadew> if I sold, I marked the bottom 2021-11-09T00:09:44 < kakium69> you suspect deception? 2021-11-09T00:10:14 < jadew> I don't know what's going on, but it's always the reverse of what I'd expect 2021-11-09T00:11:46 < jadew> I believe the guys with the loaded bots, have figured out how to clean the market 2021-11-09T00:12:18 < kakium69> I have many times thought I should buy some stock just impulsivelly and like next day or next week the stock crashes 2021-11-09T00:13:24 < jadew> I've actually done that 2021-11-09T00:13:53 < jadew> if I used a coin flip to decide my trades, I would have done better 2021-11-09T00:15:08 < kakium69> I need to invert my brain so that I buy stuff I think is shit 2021-11-09T00:15:11 < jadew> also, the fact that entire economies are moving (a lot) up and down, makes lots of valid judgements completely wrong 2021-11-09T00:15:26 < kakium69> and short stuff I'm very intrested about 2021-11-09T00:17:02 < jadew> there was a guy on reddit responding to "how do you trade in a market that does the exact opposite of what you would expect?" and he said (jokingly I think) that he prepares all his trades in the evening and in the morning does the complete opposite of that :) 2021-11-09T00:21:24 < kakium69> there are players in game who can dial stock price to value they want it to be 2021-11-09T00:21:37 < jadew> I'm getting this feeling too 2021-11-09T00:21:45 < jadew> let me post my recent history 2021-11-09T00:21:50 < kakium69> it could be profitable 2021-11-09T00:22:16 < jadew> http://5.12.190.78/stuff/history.png 2021-11-09T00:22:41 < kakium69> oof 2021-11-09T00:22:48 < kakium69> is that jeuro mani? 2021-11-09T00:22:56 < jadew> don't know what that is 2021-11-09T00:23:33 < kakium69> I don't know what I'm lookin 2021-11-09T00:23:43 < jadew> it's my profit/loss history 2021-11-09T00:23:55 < jadew> oh, it's USD 2021-11-09T00:23:58 < jadew> not EUR 2021-11-09T00:24:36 < kakium69> so Let's say "Elon Musk to sell 10% of TSLA" 2021-11-09T00:25:15 < kakium69> 1+1 = short now 2021-11-09T00:25:54 < jadew> yeah, let me show you how that worked out: http://5.12.190.78/stuff/open.png 2021-11-09T00:26:39 < jadew> it's silly 2021-11-09T00:27:19 < jadew> either the bots are playing mind games, or someone sees exactly what's on the table and they have an algorithm that can plat a path to take it all 2021-11-09T00:27:28 < jadew> *plot 2021-11-09T00:27:41 < kakium69> meanwhile someone with considerable amount of moneys can perfectly time buying/selling stock in order to profit from all the people going for shorts 2021-11-09T00:28:30 < kakium69> I don't even think it's "someone" 2021-11-09T00:28:38 < kakium69> it's computers 2021-11-09T00:28:43 < jadew> yeah 2021-11-09T00:29:32 < jadew> they either have an AI that has figured this out, or they've researched all of this thoroughly and have an algorithm that the bots are following 2021-11-09T00:30:48 < kakium69> you need AI to figth another AI 2021-11-09T00:31:04 < jadew> it's either that, or I'm too dumb to pick up on the cues that the rest of the happy traders are able to pick up 2021-11-09T00:31:04 < kakium69> in stock markets 2021-11-09T00:32:18 < kakium69> no you just participate in dumb game 2021-11-09T00:32:43 < jadew> my theory is that it's either me who is dumb, and the rest are just good at this, or I'm not dumb, but the rest are, and they're just being used by someone else, and eventually the majority of them are going to lose a lot of money 2021-11-09T00:32:46 < catphish> evening sirs 2021-11-09T00:33:05 < jadew> evening 2021-11-09T00:33:23 < catphish> monied westerners

2021-11-09T00:38:31 < jadew> like I said, if I let a coin flip decide my position I would have had more money than I do now 2021-11-09T00:39:17 < jadew> I tried all kinds of strategies

from doing it 2021-11-09T00:40:08 < jadew> so I missed on that one too 2021-11-09T00:40:44 < jadew> gold first started crashing (contrary to what I was expecting) and then it rose 2021-11-09T00:40:54

to rise in price 2021-11-09T00:45:38 < jadew> instead it got into a down trend that lasted a month - it dipped just enough to close my position, than within a week it bounced back to the price point at which I opened the position 2021-11-09T00:45:53 < jadew> *then 2021-11-09T00:46:09 < catphish> i've never had much luck with levereged positions 2021-11-09T00:46:32 < jadew> me neither 2021-11-09T00:47:00 < jadew> but the thing is that if you're able to lose so much money, so fast, then it means you can earn a lot of money just as fast 2021-11-09T00:47:06 < jadew> you just have to make the right decisions 2021-11-09T00:47:48 < kakium69> everything is priced in 2021-11-09T00:47:54 < catphish> my position was the realy dumb one, buy with cash and hold 2021-11-09T00:47:59 <

2021-11-09T00:49:56 < jadew> it seems like every strategy is accounted for and it's close to impossible to find one that makes you money 2021-11-09T00:50:15 < jadew> going long is not an option anymore 2021-11-09T00:50:15 < catphish> with that said, i have a suspicion that with retail investment as high as it is, governments will pull out all the stops to prevent sharp falls 2021-11-09T00:50:19 < jadew> because we're in a huge bubble 2021-11-09T00:50:45 < kakium69> real assets 2021-11-09T00:50:46 < catphish> jadew: you say that, but last week going long would have made

catphish> so there's no point gambing eithr way 2021-11-09T00:52:03 < catphish> better to buy shares in real assets with real potential 2021-11-09T00:52:20 < jadew> I think the best idea is to start your own business 2021-11-09T00:52:36 < jadew> if you can generate 20% return on your investment, then that's a good business 2021-11-09T00:52:51 < catphish> well that's ideal 2021-11-09T00:53:19 <

2021-11-09T00:55:48 < jadew> I wish I could, because you can use them as insurance (this is how big investors do it) 2021-11-09T00:57:05 < kakium69> I generally don't know what we are talking about

You'll figure where each of them is defined. 2021-11-12T17:35:45 < Mangy_Dog> good point 2021-11-12T17:35:52 < PaulFertser> karlp: not only that, it does something to forward-define all top-level things so that the order doesn't matter. 2021-11-12T17:36:35 < Mangy_Dog> hmmm 2021-11-12T17:36:37 < Mangy_Dog> you know 2021-11-12T17:36:41 < Mangy_Dog> i think its this spi.h 2021-11-12T17:36:47 < Mangy_Dog> thats the root of all these problems 2021-11-12T17:37:09 < Mangy_Dog> that has delay as well 2021-11-12T17:38:29 < Mangy_Dog> thats got new delays and randoms inside it 2021-11-12T17:39:37 < PaulFertser> Mangy_Dog: not surprising 2021-11-12T17:39:49 < Mangy_Dog> but like i say 2021-11-12T17:39:53 < Mangy_Dog> nothings changed 2021-11-12T17:39:57 < Mangy_Dog> this was always there before 2021-11-12T17:39:59 < PaulFertser> You say but you can't prove. 2021-11-12T17:40:10 < Mangy_Dog> just why is it acting differently now 2021-11-12T17:40:20 < PaulFertser> The errors are real and legit. 2021-11-12T17:40:24 < Mangy_Dog> youd just have to take my word for it 2021-11-12T17:40:26 < Mangy_Dog> nothings changed 2021-11-12T17:40:35 < Mangy_Dog> these files have been there 2021-11-12T17:40:38 < Mangy_Dog> all this time 2021-11-12T17:41:06 < PaulFertser> With all due respect, sorry, I won't.

Or at least a series of full backups of the whole project directory. 2021-11-12T17:45:11 < Mangy_Dog> tbh i should 2021-11-12T17:45:29 < Mangy_Dog> but i itterate and test my code so much ill have a billion backups 2021-11-12T17:45:37 < PaulFertser> git doesn't mind 2021-11-12T17:45:41 < Mangy_Dog> if its backing up at each compile 2021-11-12T17:46:02 < Mangy_Dog> or is it i have to say commit as new version? 2021-11-12T17:46:18 < Mangy_Dog> so while itterating i say... ok this is enough... submit as new version? 2021-11-12T17:48:11 < PaulFertser> Usually developers are making commits manually.

Tesla replaced due to AC charge cutting in and out" 2021-11-13T23:51:34 < kakium69> oh 2021-11-13T23:51:54 < catphish> so definitely a gamble 2021-11-13T23:52:21 < catphish> on the other hand, the tesla charger is actually 3 chargers in one box, if only 2 of them work, that's enough 2021-11-13T23:53:40 < kakium69> any pics? 2021-11-13T23:53:50 < catphish> yes but they're very very boring 2021-11-13T23:54:16 < catphish> https://www.ebay.co.uk/itm/284521285668 2021-11-13T23:54:16 < kakium69> in and out might sound like thermal issue 2021-11-13T23:54:34 < kakium69> overheat threshold 2021-11-13T23:55:00 < catphish> yep, intermittent definitely suggests overheat or a bad sensor 2021-11-13T23:55:36 < catphish> inside the box is 3 x 3.3kw CAN controlled chargers, and a master logic board 2021-11-13T23:55:42 < catphish> there's an open source replacement for the latter 2021-11-13T23:55:53 < kakium69> ah modular 2021-11-13T23:56:23 < kakium69> intermittent? 2021-11-13T23:56:27 < zyp> yeah, it's the common way to build three phase chargers 2021-11-13T23:56:32 < kakium69> not likelly overheat 2021-11-13T23:56:43 < catphish> if only 2 of them work, i'll get the 6.6kW single phase i wanted anyway 2021-11-13T23:57:34 < catphish> if all of them work with the replacement logic board, even better because less load on each 2021-11-13T23:57:47 < zyp> you'll still want to keep them as 2x16A rather than 1x32A if possible 2021-11-13T23:58:08 < zyp> in case you'd like to charge from a 3 phase 16A outlet :) 2021-11-13T23:58:08 < catphish> why's that? 2021-11-13T23:58:30 < catphish> the problem is at home i'll probably want to charge from a single phase 30A 2021-11-13T23:58:39 < catphish> and making it switchable sounds like hassle 2021-11-13T23:58:40 < zyp> it'll do that too, obviously 2021-11-13T23:58:45 < zyp> nah 2021-11-13T23:58:49 < zyp> it is switchable in the first place 2021-11-13T23:58:55 < catphish> oh okay 2021-11-13T23:59:01 < kakium69> ofc it is 2021-11-13T23:59:05 < catphish> i suppose it would have to be 2021-11-13T23:59:07 < catphish> ideal them 2021-11-13T23:59:12 < catphish> *ideal then 2021-11-13T23:59:21 < zyp> all cars I'm aware of

single phase to all of the modules 2021-11-14T00:00:17 < zyp> yep 2021-11-14T00:00:21 < kakium69> in charger side? 2021-11-14T00:00:25 < catphish> i have the source files for the open source logic board, but i have no idea what program is required to open it 2021-11-14T00:00:36 < kakium69> or charging cable side zyp? 2021-11-14T00:00:45 < zyp> charger side 2021-11-14T00:00:48 < catphish> how can single phase be connected to all 3? 2021-11-14T00:00:52 < catphish> some kind of switch in the modules? 2021-11-14T00:01:02 < zyp> yeah 2021-11-14T00:01:36 < zyp> old teslas used to require L1 and L2 to be hooked together externally for single phase charging 2021-11-14T00:01:45 < zyp> like first gen model S 2021-11-14T00:01:58 < catphish> here's some info about it https://openinverter.org/wiki/GEN2 2021-11-14T00:02:57 < catphish> this is from 2nd gen model s i believe, i'm not too worried if i need a hacky cable to make it work though 2021-11-14T00:03:05 < zyp> ah 2021-11-14T00:03:25 < zyp> the switch might be in another module between the charger and inlet in that case 2021-11-14T00:04:24 < catphish> can anyone tell me what i open this with? https://github.com/damienmaguire/Tesla-Charger/tree/master/V5 2021-11-14T00:04:28 < kakium69> could you just short L1 and L2 externally? 2021-11-14T00:04:32 < zyp> yes 2021-11-14T00:04:38 < zyp>

So if you're triggering on rising and falling, you probably need to read the pin to know which it was. 2021-11-16T06:42:57 < octorian> (or rig up some sort of circuit to let you connect the line to two different pins, then configure them to trigger on different edges) 2021-11-16T06:44:25 < octorian> Of course the most direct way to read the pin is to just read the GPIO register with the input pin state.

2021-11-19T17:07:41 < catphish> the goal is very simply to control the torque of an induction motor while maximizing efficiency 2021-11-19T17:08:27 < ventYl> catphish: if it is so much of a problem to tell rotor position, then why not just simply add position sensor?

2021-11-19T17:14:22 < catphish> so if you know the orientation of the rotor field, you can align the stator field perfectly for optimal operation, but finding that orientation is certainly beyond my ability 2021-11-19T17:14:31 < catphish> let me dig out the math involved 2021-11-19T17:14:44 < catphish> i spent weeks a couple of years studying it, to no avail 2021-11-19T17:15:18 < ventYl> I think that the need of accuracy required is only proportional to quality of regulation you are able to achieve 2021-11-19T17:15:20 < catphish> https://www.microchip.com/stellent/groups/sitecomm_sg/documents/devicedoc/en542813.pdf 2021-11-19T17:15:26 < catphish> good presentation on how to do it 2021-11-19T17:15:51 < ventYl> like if you are only able to align stator field +- 1 degree, then accuracy of +- 5 degrees should be fine IMHO 2021-11-19T17:15:56 < ventYl> at least for the first trials 2021-11-19T17:16:28 < catphish> without knowledge of the rotor field orientation, the alternative is to instead just control voltage and slip (differential frequency) 2021-11-19T17:17:29 < catphish> there is an optimal amount of slip, and an optimal voltage for every possible combination of rotor speed, and desired current (torque) 2021-11-19T17:18:05 < catphish> those are the 2 options, and everyone in the open source world uses the latter approach afaik 2021-11-19T17:18:53 < catphish> i've given up on rotor field orientation estimation, and nothing will persuade me to try again :) 2021-11-19T17:19:14 < catphish> but what i am interested in is the optimization of the voltage-slip algorithm 2021-11-19T17:20:19 -!- spacebyte [~spacebyte@193.137.28.238] has joined ##stm32 2021-11-19T17:20:50 < ventYl> that slide deck describes rotor field orientation estimation, or the other one?

2021-11-22T02:13:37 < m4t> it's not a huge deal that this happens, as it does not affect the accuracy of the generated pulse. just the "watchdog" that compares the micros() from the timer overflow() ISR to the beginning of the second detects it 2021-11-22T02:13:48 < m4t> i modified it to only apply a correction if the offset persists for multiple periods 2021-11-22T02:14:24 < qyx> which stm32 is

__HAL_TIM_SET_AUTORELOAD(&_timerObj.handle, ARR_RegisterValue); 2021-11-22T02:16:26 < qyx> stm32 has timer update event and ARR register, no overflows 2021-11-22T02:17:04 < qyx> there may be a race

2021-11-22T02:18:15 < karlp> so, what are you asking? 2021-11-22T02:18:19 < karlp> you seem to have it all figured out? 2021-11-22T02:18:36 < m4t> i guess, if there's a way to change interrupt priorities so systick takes precedence or something? 2021-11-22T02:19:07 < m4t> although i have no idea if mine is actually firing slightly before 2021-11-22T02:19:33 < m4t> i think i did figure it out after asking the question though 2021-11-22T02:20:06 < qyx> I somewhat remember this "inaccurate xtal" story 2021-11-22T02:20:15 < m4t> ya that was actually an inaccurate crystal

karlp> well, irq priorities are basic, and yes, you can, if you think that is your issue... 2021-11-22T02:21:26 < m4t> i calibrated this versus gps pps and it's ppb-level accuracy now 2021-11-22T02:22:00 < karlp> heh, did a site validation (have been updating shit) and got a warning, "must not support TLSv1.2" 2021-11-22T02:30:43 < m4t> SysTick apparently has to be the lowest priority 2021-11-22T02:31:07 < karlp> that depends on how you setu freertos actually. 2021-11-22T02:31:12 < karlp> but yes, you want to be careful. 2021-11-22T02:31:30 < karlp> and yeah, you may then want to take that information re-evaluate what your problem is 2021-11-22T02:49:07 < m4t> i think the root of the problem is that micros() isn't necessarily safe to call in an interrupt 2021-11-22T02:50:18 < m4t> i guess it's safe but not guaranteed to be accurate due to its dependence on systick 2021-11-22T03:02:36 < m4t> https://github.com/arduino/ArduinoCore-samd/issues/463 same thing-ish 2021-11-22T04:39:56 < aandrew> yeah you cannot delay in an interrupt, that's just poor design 2021-11-22T04:41:48 < m4t> who is delaying in an interrupt? 2021-11-22T05:33:11 -!- vit

Buy nucleo board, work on a project, add sensor, write code, everything works. Come back month later, nothing changed, nothing works, 2021-11-23T16:38:04 < karlp> protip: something changed :) 2021-11-23T16:38:31 < drzacek> what could be the cause for only one thread in freertos to run? all others seem to be dead 2021-11-23T16:39:03 < mawk> the threads are french 2021-11-23T16:39:05 < mawk> they're striking 2021-11-23T16:39:08 < drzacek> ah 2021-11-23T16:39:16 < mawk> except that one boss bootlicker that's running 2021-11-23T16:39:23 < jpa-> maybe the one thread called xSysLock() or whatever that is called in freertos 2021-11-23T16:39:34 < drzacek> also, does the firmware in stm32cubeide update automatically? I think it only loads new on new projects, doesn't update existing projects, amirite? 2021-11-23T16:39:41 < mawk> not auto no 2021-11-23T16:39:46 < mawk> for a given project 2021-11-23T16:40:06 < mawk> unless you mindlessly clicked "update" some day 2021-11-23T16:40:10 < drzacek> I removed one thread, so now I have defaulttask that does nothing (osdelay(500)), and the other one doesn't even start 2021-11-23T16:40:14 < mawk> just look in the generated files 2021-11-23T16:40:39 < drzacek> I do a lot of stuff mindlessly, don't think I updated. Wouldn't even know where is that option 2021-11-23T16:41:29 < ventYl> mawk: :D 2021-11-23T16:51:05 < karlp> whee, segfaulted ngspice 2021-11-23T16:54:37 < drzacek> okay 2021-11-23T16:55:48 < karlp> --enable-newpred Enable NEWPRED whatever it is(?) 2021-11-23T16:56:00 < karlp> nice one guys, "you must have help text for the options" ok! 2021-11-23T16:56:00 < drzacek> so what was new, I opened my project today, removed one timer cause I didn't needed it anymore, wanted to generate code in cubemx view, it complained about the "USE_NEWLIB_REENTRANT". I had this project running previously with Freertos and this was not set, yet it somehow worked? 2021-11-23T16:56:18 < karlp> "nothing changed" :) 2021-11-23T16:56:20 < mawk> lol karlp 2021-11-23T16:56:22 < drzacek> anyways, I activated it, it compiles, it uploades, and it runs only first (default) task 2021-11-23T16:56:44 < mawk> are you using anything from newlib? 2021-11-23T16:56:50 < mawk> malloc, printf, etc 2021-11-23T16:56:54 < qyx> so do a version bisect 2021-11-23T16:57:00 < drzacek> I'm not sure what is in newlib 2021-11-23T16:57:03 < qyx> it is simple with git 2021-11-23T16:57:07 < drzacek> I assumed it was the stm32 version of libc? 2021-11-23T16:57:10 < mawk> newlib is libc 2021-11-23T16:57:26 < mawk> if you call a function that is not from hal or freertos then it's likely in newlib 2021-11-23T16:57:28 < drzacek> sooo I kinda need it always? 2021-11-23T16:57:32 < mawk> unless it's a funky compiled intrinsic 2021-11-23T16:57:33 < drzacek> oh 2021-11-23T16:57:33 < mawk> yes 2021-11-23T16:57:57 < mawk> but there are some functions that need special handling with threads 2021-11-23T16:58:04 < mawk> malloc, some printf calls 2021-11-23T16:58:24 < mawk> they need you to provide reentrancy support 2021-11-23T16:58:25 < drzacek> well what wonders me, it didn't complained about that option before 2021-11-23T16:58:51 < mawk> reentrancy support is being able to call the function while a suspended thread is in the middle of calling it 2021-11-23T16:59:22 < mawk> or for functions with internal state, calling it twice; but only a few libc functions are ugly like that 2021-11-23T16:59:28 < drzacek> that's how I understood it - so the functions can be paused or whatever, so other thread or irq can run 2021-11-23T16:59:37 < mawk> yeah 2021-11-23T16:59:46 < mawk> well the idea is provide each thread with its own reent context 2021-11-23T16:59:51 < mawk> so they don't fight each other 2021-11-23T16:59:51 < drzacek> it looks like I am using the vsnprintf for uart debugging 2021-11-23T17:00:03 < mawk> with float values? 2021-11-23T17:00:07 < mawk> or stuff like that 2021-11-23T17:00:15 < drzacek> but that hasn;'t changed, I used it before 2021-11-23T17:00:18 < mawk> a 2021-11-23T17:00:18 < drzacek> no floats 2021-11-23T17:02:22 < drzacek> dont know what I did, but NOW it IS updating the fw package in that project 2021-11-23T17:02:38 < mawk> more up to date is better 2021-11-23T17:02:51 < drzacek> wish it asked me before it did it 2021-11-23T17:03:05 < mawk> well in my memories it asks 2021-11-23T17:03:08 < mawk> and you can say no 2021-11-23T17:03:13 < mawk> maybe they changed it 2021-11-23T17:03:26 < mawk> or maybe it's just updating the local repo of hal fw and not your project's 2021-11-23T17:03:27 < drzacek> https://imgur.com/a/PJdtsss 2021-11-23T17:03:33 < mawk> at least with cubemx that's how it was 2021-11-23T17:03:50 < mawk> ah 2021-11-23T17:03:53 < mawk> that's just a warning 2021-11-23T17:03:57 < mawk> you can say no if you want 2021-11-23T17:04:06 < drzacek> sounds serious tho 2021-11-23T17:04:06 < mawk> if you don't need it 2021-11-23T17:04:14 < mawk> well it's because it takes you for a dummy 2021-11-23T17:04:32 < mawk> if you know what you're doing and you need the extra memory it takes say no 2021-11-23T17:04:51 < mawk> anyway enabling that flag alone isn't enough to make it reentrant anyway 2021-11-23T17:04:58 < drzacek> well, IT is not wrong 2021-11-23T17:04:59 < mawk> if nothing changed since I last looked at it 2021-11-23T17:05:00 < drzacek> I am a dummy 2021-11-23T17:05:10 < mawk> lol 2021-11-23T17:05:23 < drzacek> dunno what it does, I generated withtout this flag and now it runs 2021-11-23T17:05:30 < mawk> good 2021-11-23T17:06:16 < drzacek> so what exactly is this thing? when will I need it? if I used some newlib functions, instead sticking to hal/cmsis? 2021-11-23T17:06:52 < drzacek> the risks are what, that some functions just wont let me preempt, and realtime gonna be borked, or even worse - whole program will crash? 2021-11-23T17:10:01 < mawk> you can use newlib 2021-11-23T17:10:22 < mawk> but some functions need reentrancy like malloc, printf for floats, maybe other stuff 2021-11-23T17:10:32 < mawk> just don't use them and that's it I guess 2021-11-23T17:25:25 < drzacek> ok, thanks 2021-11-23T17:25:28 -!- drzacek [~drzacek@130-062-074-080.ip-addr.inexio.net] has quit [Quit: Leaving] 2021-11-23T17:54:14 < qyx> off don't use malloc 2021-11-23T17:54:24 < qyx> *pff 2021-11-23T17:54:40 < qyx> have you seen a single program without malloc?

2021-11-24T14:23:25 < ventYl> unfortunately you have to turn that warning on 2021-11-24T14:23:26 < catphish> because the person who wrote this code originally ignored about 100 compiler warnings, so i'm left doing the same 2021-11-24T14:23:28 < ventYl> even in 2021 2021-11-24T14:23:39 < catphish> i really need to fix it 2021-11-24T14:23:45 < catphish> i hate working on other people's code 2021-11-24T14:23:46 < ventYl> which leads to that ^^^ situation 2021-11-24T14:23:58 < catphish> thanks :) 2021-11-24T14:24:18 < ventYl> -Wall is the very fist switch which I pass to the compiler 2021-11-24T14:24:28 < catphish> yeah i do the same 2021-11-24T14:24:35 < ventYl> sometimes even -pedantic 2021-11-24T14:24:47 < catphish> actually most of the warning in this code are "warning: ISO C++ forbids converting a string constant to 'char*' " 2021-11-24T14:24:57 < catphish> so i can probably sort them 2021-11-24T14:25:05 < PaulFertser> You can disable it selectively -Wno-... 2021-11-24T14:25:28 < catphish> is a string constant in c++ not a char* (obviously not) 2021-11-24T14:25:48 < catphish> i'm writing c++ but i don't actually *know* c++ 2021-11-24T14:25:59 < catphish> but i don't pay you to judge me 2021-11-24T14:26:21 < catphish> works great now anyway, thanks! 2021-11-24T14:26:28 < ventYl> that warning makes sense 2021-11-24T14:26:46 < ventYl> because with C attempt to write into const variable is undefined (and generally works, IME) 2021-11-24T14:26:59 < ventYl> while C++ requires them to be in read-only section, so a write attempt will fail 2021-11-24T14:27:04 < ventYl> i learned that the hard way 2021-11-24T14:27:18 < catphish> ah that makes sense 2021-11-24T14:27:28 < catphish> so they're const char* 2021-11-24T14:27:58 < ventYl> they are const char[] 2021-11-24T14:28:01 < ventYl> that's a bit different 2021-11-24T14:29:11 < catphish> just adding "const" to this line solved most of the warnings https://paste.debian.net/1220651/ 2021-11-24T14:30:32 < catphish> (not my code) 2021-11-24T14:37:41 < ventYl> that makes sense 2021-11-24T14:53:38 < Steffanx> Time to pull catphish 's strings 2021-11-24T15:00:34 -!- nerozero [~nerozero@87.253.63.54] has quit [Ping timeout: 260 seconds] 2021-11-24T15:00:54 -!- nerozero [~nerozero@87.253.63.54] has joined ##stm32 2021-11-24T15:20:47 < BrainDamage> to be pedantic, what's const is the pointer, what's undefined if the content should be constant as well 2021-11-24T15:21:31 < BrainDamage> and that's why it works, when you write, you don't change the starting pointer 2021-11-24T15:24:37 < zyp> nope 2021-11-24T15:24:50 < zyp> const foo* is pointer to const foo 2021-11-24T15:25:03 < catphish> i was of the same understanding as zyp 2021-11-24T15:25:09 < zyp> foo* const is const pointer to non-const foo 2021-11-24T15:25:27 < zyp> and const foo* const is const pointer to const foo 2021-11-24T15:25:51 < BrainDamage> ah, my bad, you're right 2021-11-24T15:26:14 < zyp> const pointers are not very useful and therefore not used much 2021-11-24T15:26:30 < zyp> you generally only care about whether whatever you're pointing to is const 2021-11-24T15:26:59 < ventYl> if you need const pointer then simply use reference 2021-11-24T15:27:06 < ventYl> you'll get syntactic sugar for free 2021-11-24T15:27:15 < ventYl> "there's no pointer involved" 2021-11-24T15:28:42 < zyp> in general, const is useful to say that you're passing a readonly object by reference 2021-11-24T15:29:48 < zyp> pointers are generally passed by value, and you don't care whether the original is readonly or not when making a copy 2021-11-24T15:32:23 < ventYl> i think i've seen that exactly once 2021-11-24T15:32:46 < ventYl> and the meaning was "under no circumstances touch anything else than what I gave you" 2021-11-24T15:33:22 < zyp> it's still meaningless 2021-11-24T15:33:51 < zyp> int ptr* const; ptr[5] = 7; is perfectly valid 2021-11-24T15:34:18 < jpa-> inside a class it still makes kind of sense, i.e. don't change after initialization 2021-11-24T15:34:40 -!- spacebyte [~spacebyte@a94-132-168-30.cpe.netcabo.pt] has quit [Quit: leaving] 2021-11-24T15:34:48 < jpa-> i've also used void * const * arg which is wonderfully confusing for beginners :) 2021-11-24T15:35:15 < ventYl> zyp: well, you can ignore it if you want. but it will raise one more no-no warning finger 2021-11-24T15:35:36 < ventYl> and in the end someone can come and ask "it was const anyway, why did you fuck with it?" 2021-11-24T15:35:44 < zyp> jpa-, references are generally better for that 2021-11-24T15:36:02 < jpa-> yeah, if it is always non-null 2021-11-24T15:36:21 < zyp> why do you have constant nullpointers?

Nop probably not much use out of it, but at least, it keeps one entertained 2021-11-24T16:39:59 < Xogium> so… You can't memory map the qspi in linux ? 2021-11-24T16:40:03 < ventYl> and there's one particular annoying design feature of ARM MPU - region must be size-aligned 2021-11-24T16:40:03 < qyx> Xogium: I stopped when it refused to start shell interpreter 2021-11-24T16:40:17 < Xogium> :O 2021-11-24T16:40:21 < ventYl> and size must be power-of-two 2021-11-24T16:40:33 < qyx> but the kernel was working, userspace somehow 2021-11-24T16:41:20 < Xogium> mmh 2021-11-24T16:42:24 < ventYl> memory mapping QSPI via XIP probably has nothing to do with MPU 2021-11-24T16:42:42 < ventYl> *QSPI flash 2021-11-24T16:42:55 < Xogium> well if anyone is bored 2021-11-24T16:42:56 < Xogium> https://git.lumina-sensum.com/LuminaSensum/buildroot-stm32f769-disco 2021-11-24T16:44:20 < Xogium> it works, even if it is very tiny and minimal. About 9 mb of ram free 2021-11-24T16:45:07 < qyx> I did map QSPI in the address space 2021-11-24T16:45:17 < Xogium> yeah… don't try a full busybox with that ;) I know, I tried it 2021-11-24T16:45:37 < qyx> busybox was the thing that didn't work for me 2021-11-24T16:45:50 < Xogium> probably because you didn't minimalize it 2021-11-24T16:45:57 < Xogium> wait… is that even a word ? Anyway 2021-11-24T16:46:21 < qyx> it did panic whenever busybox's shell interpreter was run 2021-11-24T16:46:28 < Xogium> really ? 2021-11-24T16:46:31 < Xogium> hmm 2021-11-24T16:46:35 < Xogium> strange 2021-11-24T16:46:50 < Xogium> for me it didn't panic it just… failed to allocate enough memory for poor getty to even run 2021-11-24T16:47:58 < Xogium> so wait you did map the full qspi in ? So you could execute in place from it ? 2021-11-24T16:48:19 < Xogium> but why would XIP not be worth it in linux ? I mean, it should allow to save quite a bit of ram shouldn't it ? 2021-11-24T16:48:25 < Xogium> at least from my understanding 2021-11-24T16:49:26 < ventYl> MPU != XIP 2021-11-24T16:49:37 < ventYl> at least at my end MPU stands for memory protection unit 2021-11-24T16:50:09 < Xogium> so the MPU would forbid you from using XIP ? 2021-11-24T16:50:13 < Xogium> I didn,t know that 2021-11-24T16:50:22 < Xogium> but, that sort of makes sense 2021-11-24T16:50:58 < Xogium> I suppose you could always not enable it in linux but… yeah. Hmm 2021-11-24T16:51:02 < ventYl> no, it wouldn't. I just think, it doesn't make sense to play with MPU in linux at all 2021-11-24T16:51:09 < ventYl> if it is not enforced by the linux by default 2021-11-24T16:51:18 < Xogium> I know u-boot spl manages to XIP straight to full u-boot somehow 2021-11-24T16:54:43 < Xogium> well this was still a fun one to pull off… 2021-11-24T16:55:51 < Xogium> I also tried to toy a bit with rtos, but honestly… the only one I found that worked almost ok was mbed. Zephyr has broken usb I believe, no audio though it can easily be ported via the bsp, and sdram support is experimental and very very much broken 2021-11-24T16:56:40 < Xogium> freertos has some problems too, I can't remember which. Nutx seems very nice, but the kconfig menu are quite cluttered 2021-11-24T16:57:24 < Xogium> and there was this chinese rtos I tried, what was the name again… Doc was ab so lu te ly awefull 2021-11-24T16:57:33 < qyx> chibios? 2021-11-24T16:57:40 < Xogium> hmm nah 2021-11-24T16:57:50 < Xogium> damn I totally blanked on the name XD 2021-11-24T16:57:50 < qyx> sounds chinese 2021-11-24T17:00:46 < Xogium> ahah found it 2021-11-24T17:00:52 < Xogium> rt-thread 2021-11-24T17:01:09 < ventYl> there's mynewt hosted by apache 2021-11-24T17:01:23 < ventYl> not anything exciting trough 2021-11-24T17:01:31 < ventYl> and there's mine, which doesn't have any public sources 2021-11-24T17:01:40 < Xogium> ah, didn't know that one… I don't know many rtos yet tbh. 2021-11-24T17:02:10 < qyx> I forgot what mynewt is 2021-11-24T17:02:16 < Xogium> mbed has some bugs here and there, but overall it is the only one I found that supports the entire set of hardware on the disco board… 2021-11-24T17:04:02 < Xogium> ironically I think the fact I can understand most of the demo programs I found for mbed is because they are simpler… Yeah that sounds weird right ? Mcu programming seeming simpler than say, python or even actual C programming on a full computer 2021-11-24T17:04:28 < Xogium> comments help too, but for the first time ever, I feel like I can understand what some piece of code does 2021-11-24T17:05:36 < Xogium> I'd not say I can code all I want on my own, not at all… but I can sort of get by if I carefully make adjustments to some existing code 2021-11-24T17:06:49 < Xogium> I'm still very bad at syntax though :D 2021-11-24T17:08:27 < Xogium> I even got espeak to run on mbed rtos 2021-11-24T17:09:07 < Xogium> heavily cut down version of espeak mind you, like… no emoji support, no more than one language and one voice, ... but it runs 2021-11-24T17:10:59 < Xogium> I wanted to see if I could run espeak without using the external flash and ram… Success ;) 2021-11-24T17:12:24 < Xogium> I didn't ever do bare metal yet 2021-11-24T17:12:53 < ventYl> that's not much of a difference 2021-11-24T17:13:23 < Xogium> yeah… I suppose not is it ? I mean, my understanding is that a rtos is well, fancier bare metal of sort, cause you get threads 2021-11-24T17:14:23 < ventYl> you can have threads without rtos too and you can have rtos-es which doesn't support threads (like OSEK doesn't support preemptive multithreading by default) 2021-11-24T17:14:32 < Xogium> hmm 2021-11-24T17:14:34 < ventYl> RTOS is just a matter of standardized API 2021-11-24T17:14:39 < Xogium> ah 2021-11-24T17:15:00 < Xogium> my understanding was that rtos added threads, otherwise all you could use were interrupts 2021-11-24T17:15:04 < ventYl> so if you have two pieces of code written for the same RTOS your hope for them to cooperate is bigger than if they are written bare metal 2021-11-24T17:15:22 < Xogium> ah yeah 2021-11-24T17:15:30 < ventYl> well, a thread switcher is merely just one array and two or three functions 2021-11-24T17:15:31 < Xogium> so rtos are better for that, I suppose 2021-11-24T17:15:37 < ventYl> I wouldn't call than an RTOS 2021-11-24T17:15:51 < karlp> well, some rtos's only standardize apis on things related to os services, not anything to do with the HAL. 2021-11-24T17:16:13 < ventYl> that's okay approach 2021-11-24T17:16:27 < ventYl> as long as you don't standardize something as fugly as freertos naming conventions 2021-11-24T17:17:00 < Xogium> but what do you guys typically do ?

Like, you can't even map some part of the internal flash into memory 2021-11-24T17:54:25 < Xogium> kinda surprised me actually 2021-11-24T17:54:33 < ventYl> it has memory mapped flash, albeit external 2021-11-24T17:54:39 < ventYl> it doesn't carry any on-chip flash 2021-11-24T17:54:48 < ventYl> so you *have* to memory map flash 2021-11-24T17:54:55 < ventYl> by a code residing in that flash :> 2021-11-24T17:55:16 < Xogium> even though some guy came up with a workaround on the rpi forum which is… Mind boggling to me: set aside a region of the flash and mark it as invalid, and when the cpu hit the page fault for it, trap the signal and make it go to the flash 2021-11-24T17:55:20 < Xogium> or something like that 2021-11-24T17:56:05 < Xogium> which makes evern ram transaction pass through spi… 2021-11-24T17:56:09 < Xogium> *every 2021-11-24T17:56:53 < ventYl> right now I am not sure if I understand, what do you mean by memory mapped flash 2021-11-24T17:57:06 < ventYl> is it the same as XIP from QSPI flash? 2021-11-24T17:57:39 < catphish> i didn't look at the QSPI flash stuff at all yet because i'm just using a pi pico 2021-11-24T17:57:59 < catphish> but i assume the ROM takes care of it 2021-11-24T17:58:30 < ventYl> it works in a funny way 2021-11-24T17:59:03 < ventYl> mask rom assumes that shit connected to certain pins can be talked to using one of ~three protocols 2021-11-24T17:59:42 < ventYl> it attempts to read first 256 bytes out of it. calculates CRC and if it matches, jumps at offset 0 of that 256 byte block 2021-11-24T18:00:15 < ventYl> it is a responsibility of that block to configure XIP for shit connected to QSPI and then jump anywhere convenient 2021-11-24T18:00:22 < ventYl> to start executing out of flash 2021-11-24T18:01:10 < Xogium> well maybe I misunderstood but… It seemed like the rp2040 itself doesn't have memory mappable flash 2021-11-24T18:01:17 < ventYl> (that 256 byte block is executed out of RAM after being read out by rom bootloader, not from flash) 2021-11-24T18:01:35 < ventYl> rp2040 doesn't contain any flash on-chip 2021-11-24T18:01:55 < Xogium> oh 2021-11-24T18:02:04 < ventYl> you have to attach one externally and provide stub which memory-maps it 2021-11-24T18:02:21 < ventYl> in theory, that stub exists and you can simply throw it in as a blob 2021-11-24T18:02:22 < Xogium> isn't that strange ?

2021-11-24T18:13:23 < ventYl> IIRC size doesn't matter, or it defaults to maximum allowable size, so if you read beyond end of flash, you'll get random garbage or whatever flash responds with using XIP protocol 2021-11-24T18:13:58 < ventYl> all that matters is what procotol your flash is using and the piece of code tries to be smart-ass, figure that out and configure it properly 2021-11-24T18:14:23 < ventYl> so this is piece of code is not future proof as it depends on compatibility of new parts with old protocols 2021-11-24T18:16:10 < ventYl> it would probably be better if there was 16kB of flash instead of ROM, so one could reflash stage1 bootloader, but then there would be a question if "isn't 16kB too few" and "do we really need an external flash?" and similar 2021-11-24T18:16:35 < ventYl> maskrom is also probably cheaper and smaller to be manufactured compared to flash 2021-11-24T18:21:35 < Xogium> scary stuff 2021-11-24T18:22:54 < ventYl> probably not that scary as it sounds as it all boils down to two or three variants which covers lik 95% of SPI FLASH 2021-11-24T18:23:00 < ventYl> but one has to check for compatibility 2021-11-24T18:23:41 < ventYl> which is two-fold: 1) will stock bootloader work with my flash 2) will my binary image work for someone with different flash?

I open the app, so far so good, I can navigate around pretty easily, I go in new project, then I select new stm32 project… and I litterally get stuck on the cancel button in the new project dialog XD 2021-11-29T22:43:23 < Xogium> tab, arrows, even the special review mode of the screen reader did not work 2021-11-29T22:43:55 < PaulFertser> mawk: yes, and why do not they work? Because nano is made by insane ubuntu lovers. 2021-11-29T22:44:12 < mawk> lol 2021-11-29T22:47:19 < Xogium> but to be honest, I think in the future I might have to use only the pure tty, because the gui world of linux is getting kind of a bit scary with accessibility… The devs look at at-spi and at all sort of accessibility for blind people, and they don't know what that's used for so they want to rip it all out.
