2022-10-01T00:16:13 < upgrdman> lunix pros: is there a simple tool to verify two files are exactly the same? they are binary files, and VERY large (too big to fit in RAM)
2022-10-01T00:17:51 < Xogium> cmp
2022-10-01T00:18:15 < Xogium> if it doesn't talk they are identical, otherwise it will tell you they aren't
2022-10-01T00:19:15 < zyp> I tend to shasum them
2022-10-01T00:19:17 < upgrdman> nice, thx
2022-10-01T00:19:20 < Xogium> that too
2022-10-01T00:19:41 < Xogium> but byte to byte comparison is nice, you can know where they differ to some extent
2022-10-01T00:20:23 < upgrdman> does cmd.exe have some like that too?
2022-10-01T00:20:27 < upgrdman> something*
2022-10-01T00:20:36 < Xogium> I've honestly got no idea about that
2022-10-01T00:20:53 < zyp> indeed, depends what differences you expect and what you need the knowledge for
2022-10-01T00:21:20 < upgrdman> im just testing my code that exports files. rewriting it to use threads, want to make sure the results are the same :)
2022-10-01T00:21:27 < upgrdman> each file is ~400GB
2022-10-01T00:21:35 < zyp> calculating a checksum has the advantage you don't need to reread both files if you regenerate one
2022-10-01T00:21:38 < Xogium> diffoscope is also a great tool, but I believe it loads to ram to show a comparison, not sure
2022-10-01T00:21:50 < zyp> in your case I'd totally do checksums
2022-10-01T00:21:55 < upgrdman> k
2022-10-01T00:21:56 < zyp> since that's all you care about
2022-10-01T00:22:06 < Xogium> yeah checksum should do it
2022-10-01T00:22:47 < Xogium> diffoscope helped me figure out why my erofs filesystem wasn't reproducible in buildroot ;p gotta love that tool
2022-10-01T00:22:49 < zyp> you can calculate the known good checksum once, and then calculate checksums of the file you're testing multiple times
2022-10-01T00:22:56 < zyp> also don't need to keep the known good file around

2022-10-01T01:04:16 < qyx> ok mouser is dead wrt stm32
2022-10-01T01:04:25 < qyx> farnell has plenty of stuff
2022-10-01T01:12:01 < kaki> PaulFertser: how is life?
2022-10-01T01:18:58 < qyx> I just opened chibios github
2022-10-01T01:19:08 < qyx> immediate heart attack
2022-10-01T01:19:14 < qyx> they are still using svn in 2022
2022-10-01T01:19:26 < qyx> also
2022-10-01T01:19:27 < qyx> Mass change: Source code convention changed from CRLF to just CR (Unix).
2022-10-01T01:19:28 < qyx> wut
2022-10-01T01:21:18 < qyx> ok thats not the code I want to use anymore
2022-10-01T01:32:34 < upgrdman> i need to feed some op amps +/- voltage rails. exact voltage isn't critical, around +/-3.3 or +/-5V is fine. what's a simple and cheap way to do that which isn't too noisey? any idea of a switched capacitor ic is good enough to power a dozen op amps?
2022-10-01T01:33:18 < upgrdman> or is there some trick to power it via GPIOs feeding caps and diodes to pump up some rails?

2022-10-01T01:37:45 < upgrdman> shit, an rs232 driver may be good enough. hmmm
2022-10-01T01:38:00 < qyx> heh, yes
2022-10-01T01:40:08 < upgrdman> any idea what the cheapest common one is?
2022-10-01T01:40:23 < upgrdman> or if there's some 74 series logic that has something like it
2022-10-01T01:40:50 < qyx> they have compatible footprints
2022-10-01T01:40:56 < qyx> max232 probably
2022-10-01T01:41:19 < qyx> but those are 2+2 channels
2022-10-01T01:41:26 < qyx> maybe there are some with less
2022-10-01T01:41:40 < qyx> as you don't need them
2022-10-01T01:42:10 < upgrdman> looks like 75232-series is cheapest in stock on digikey
2022-10-01T01:42:17 < upgrdman> hmm
2022-10-01T01:43:13 < upgrdman> aww, it doesnt have internal pump
2022-10-01T01:43:14 < upgrdman> fuck

2022-10-01T12:37:13 < invzim> automatic payments in paypal=use balance with crappy conversion rates (+ messing up my accounting)

2022-10-01T15:50:14 < specing> invzim: afaik it can't be set to use your bank's conversion, they love making you use their shitty rates
2022-10-01T15:50:26 < specing> *to automatically use that
2022-10-01T15:50:34 < specing> you have to select it each and every time
2022-10-01T15:53:54 < invzim> I haven't seen an 'undo' button, I presume a refund or whatever only will make accounting worse
2022-10-01T16:06:16 < invzim> lesson learned I guess is to never use PayPal for payments on alibaba (or other places) if you inted your CC to be charged
2022-10-01T16:09:08 < specing> invzim: you can use paypal there?
2022-10-01T16:09:13 < specing> I thought it was all alipay
2022-10-01T16:18:59 < invzim> I picked PayPal, but in practice it's alipay->paypal
2022-10-01T16:19:24 < invzim> which set up the automatic thingie (I guess), which automatically uses your balance+crappy exchange rate

2022-10-01T21:55:52 < kaki> bop is from "bebop"
2022-10-01T21:56:39 < kaki> "Bebop or bop is a style of jazz developed in the early-to-mid-1940s in the United States. The style features compositions characterized by a fast tempo, complex chord progressions with rapid chord changes and numerous changes of key, instrumental virtuosity, and improvisation based on a combination of harmonic structure, the use of scales and
2022-10-01T21:56:39 < kaki> occasional references to the melody. "

2022-10-02T22:15:02 < kaki> ofc
2022-10-02T22:15:12 < kaki> soon sun goes hiding for months
2022-10-02T22:17:03 < kaki> you can try to stay moving but it just slows you down
2022-10-02T22:18:38 < kaki> some people are ofc more affected than others

2022-10-02T22:35:06 < Steffanx-> lol nice transition
2022-10-02T22:37:05 < zyp> welcome to norway :D
2022-10-02T22:40:41 < qyx> but hey recently I checked one of our offcially recognised class 3. public roads https://bin.jvnv.net/file/RU29e/P1130706.JPG
2022-10-02T22:41:40 < zyp> first couple of minutes of the video seems to mostly be about drivers unaccustomed to winter roads
2022-10-02T22:44:51 < kaki> https://www.youtube.com/watch?v=2-S8coLeXcg
2022-10-02T22:46:45 < kaki> and there is like 10-20kilometers of this
2022-10-02T22:47:22 < kaki> also tunnels that are just big enough for a tourist coach to go through
2022-10-02T22:47:56 < zyp>  ah, we have tourist roads too: https://www.youtube.com/watch?v=NoyaPaNzbrk
2022-10-02T22:48:02 < kaki> never go in there in your own car
2022-10-02T22:50:30 < kaki> zyp: definitelly difficult serpentine road but nowhere near the amount of traffic that amalfi had
2022-10-02T22:52:09 < kaki> https://www.youtube.com/watch?v=hUthVS7iKiM see this shit.. imagine 10km of this :D
2022-10-02T22:54:45 < kaki> it's not just one corner

2022-10-02T23:17:42 < kaki> I'm not very pro in terms of metal genres
2022-10-02T23:18:04 < qyx> dragonforce thru the fire and flames for example
2022-10-02T23:18:17 < qyx> https://www.youtube.com/watch?v=EB32uwVNBLs

2022-10-02T23:18:56 < kaki> I call that metal genre "tilu lilu"
2022-10-02T23:20:02 < Steffanx-> "Mouser doesn't sell this product in your region". Just when digikey is out-of-stock.
2022-10-02T23:20:16 < Steffanx-> Can't order from farnell because .. im not a company. I guess its time to be one.
2022-10-02T23:20:31 < qyx> wut
2022-10-02T23:20:39 < kaki> by sound of guitars that make very rapid "tilu lilu" sound

2022-10-02T23:46:35 < qyx> hm, the new ensiferum is okish although two or three songs have very similar melody to some older ones
2022-10-02T23:46:57 < kaki> I have never listened ensiferum
2022-10-02T23:47:10 < qyx> you pasted it ^
2022-10-02T23:47:22 < kaki> I just remembered from some metalheads saying ensiferum was good
2022-10-02T23:47:50 -!- specing_ is now known as specing
2022-10-02T23:49:46 < kaki> is there a metal genre where you cannot even make sense of the lyrics?
2022-10-02T23:49:53 < kaki> basically just screaming?
2022-10-02T23:50:50 < kaki> we call it "örinä hevi"
2022-10-02T23:51:24 < kaki> would translate into gruntting heavy
2022-10-02T23:52:15 < kaki> lyrics are just the vocalist gruntting loudly
2022-10-02T23:53:01 < BrainDamage> growl
2022-10-02T23:53:08 < kaki> yes growl
2022-10-02T23:53:12 < BrainDamage> that's the "singing" tecnique
2022-10-02T23:53:22 < kaki> :D
2022-10-02T23:53:26 < kaki> depends
2022-10-02T23:53:37 < BrainDamage> something like trash metal often has growl
2022-10-02T23:53:50 < BrainDamage> try sepultura
2022-10-02T23:55:01 < kaki> how long you guys have been metal heads?
2022-10-02T23:55:30 < BrainDamage> I'm not particularly a metal head, I like rock more
2022-10-02T23:55:35 < kaki> sepultura has quite clear vocals

2022-10-03T00:00:14 < kaki> what was the moment? when you realized you like metal? which song?
2022-10-03T00:01:54 < Steffanx-> Metal is the best music for when your down and depressed. It's really inspiring and lifts your mood. 
2022-10-03T00:05:15 < kaki> I rather like metal that embraces the melancholy
2022-10-03T00:07:35 < kaki> and also the pop metal
2022-10-03T00:09:58 < qyx> kaki: nightwish over the hills and far away
2022-10-03T00:10:40 < kaki> damn
2022-10-03T00:11:30 < kaki> it was a bop when it was released

2022-10-03T11:15:37 < qyx> I found this https://github.com/martin-ger/ESP8266-WiFi-Socket

2022-10-03T11:18:05 < qyx> I realised I have some stuff here which would be good to run when there is surplus energy available
2022-10-03T11:18:16 < zyp> but yeah, I'd expect anything common to be supported
2022-10-03T11:19:24 < zyp> you can look it up on https://www.home-assistant.io/integrations/ before you buy
2022-10-03T11:20:24 < zyp> for esp stuff, maybe https://esphome.io/
2022-10-03T11:20:28 < qyx> hm I didn't use my brain that way
2022-10-03T11:21:41 < zyp> I think that esphome thing is «build your own whatever or grab some off the shelf shit with esp and flash custom firmware»
2022-10-03T11:22:13 < qyx> basically a 10 line firmware with MQTT should work
2022-10-03T11:22:30 < qyx> I guess there is a ready made one too for somple relay toggling

2022-10-03T19:16:16 < tomeaton17> Hi, is it possible to configure the i2c peripheral so that it ignores slave NACK?
2022-10-03T19:17:25 < tomeaton17> Ti dmp has a IGNACK bit which you can set and I am hoping that stm32 has something similar but couldn't find anything in the RM.
2022-10-03T19:17:32 < karlp> what's the goal?
2022-10-03T19:18:05 < karlp> I mean, if the slave is naking, pretending it's not doesn't really sound like it helps much?
2022-10-03T19:18:20 < tomeaton17> There is a protocol very similar to i2c expect the 9th bit is a don't care
2022-10-03T19:18:27 < tomeaton17> And I would like to use that
2022-10-03T19:22:33 < tomeaton17> Doesn't seem like there is an equivalent bit to disable the nack unfortunately. Might have to write my own driver.

2022-10-04T13:47:46 < srk> typical automagic surprises 
2022-10-04T13:48:36 < BrainDamage> it's reinventing package management in a worse way, "content curation is hard, so we won't do it"
2022-10-04T13:54:39 < ventYl> TBH the only dependency management which ever kind of worked was autohell
2022-10-04T13:54:53 < ventYl> it sucks, so everyone has to play nice with everyone else
2022-10-04T13:55:27 < ventYl> once you start coupling things together tightly using some "we selected this for you" mechanism, things go fishy very fast
2022-10-04T13:57:12 < jpa-> IMO platformio package/dependency management works quite ok
2022-10-04T13:57:32 < jpa-> i don't like the autodiscovery, but you can just explicitly list the libraries

2022-10-04T14:00:52 < karlp> I'm 99% sure that the "sqlite pulls in doom" is a platformio include path corruption fail.
2022-10-04T14:01:04 < karlp> oh, we're actualyl talking about anyway
2022-10-04T14:01:06 < karlp> lol
2022-10-04T14:06:13 < jpa-> yeah, framework-arduino-mbed is a mess though, and for some reason there is no clean rp2040 picosdk available on platformio
2022-10-04T14:06:28 < jpa-> instead you have to get this package that forces mbedos and all kinds of crap into the system
2022-10-04T14:08:05 < jpa-> funny thing is that because the libraries/doom/src/config.h is pretty standard HAVE_STDLIB_H etc. stuff, it might even work for sqlite :P

2022-10-04T14:13:55 < jpa-> you put your nose close to it and inhale
2022-10-04T14:14:05 < jpa-> if it smells burned, there is a bus conflict
2022-10-04T14:14:19 < jpa-> if it smells like ozone, there is overvoltage condition

2022-10-05T00:17:41 < rustyaxe> tho im curious.. the usb port is just for power, so im guessing i prolly should look into a serial capable bootloader?

2022-10-05T00:24:40 < upgrdman> it'll be a pain in the ass to escape all the quotes, etc.
2022-10-05T00:25:22 < qyx> I did it by "compressing" all the html as a uncompressed cpio archive
2022-10-05T00:25:31 < qyx> and linking it as an individual section
2022-10-05T00:25:43 < qyx> then I had helpers to read files from the cpio archive
2022-10-05T00:26:04 < qyx> I guess esp32 maker guys will have a solution for this
2022-10-05T00:26:15 < qyx> for their esp32 webservers
2022-10-05T00:29:54 < BrainDamage> you can always base64 encode it

2022-10-05T14:28:34 < jadew> can someone please give me the TL;DR for why I would want to use protobuf over other object serialization methods?
2022-10-05T14:29:18 < qyx> what are "other object serialisation methods"?
2022-10-05T14:29:35 < jadew> packing everything in order for example
2022-10-05T14:29:40 < jadew> json could be another example

2022-10-05T14:31:05 < Laurence_b> keeek this is what kiwifarms posts look like irl
2022-10-05T14:31:20 < Laurence_b> thought they might be middle aged autistic housewives
2022-10-05T14:31:32 < qyx> jadew: platform independence, language independence, coolness, IDL, packing effectivity (varints, etc.)
2022-10-05T14:31:44 < jadew> is that the British thought police?
2022-10-05T14:32:00 < Laurence_b> yeah but the kiwifarms aspect is lulzy
2022-10-05T14:32:08 < Laurence_b> >ten year old daughter with autism
2022-10-05T14:32:13 < Laurence_b> the autism is inherited
2022-10-05T14:32:27 < jadew> qyx, yeah... I'm not sold
2022-10-05T14:32:28 < jadew> thanks
2022-10-05T14:32:49 < qyx> haha
2022-10-05T14:33:42 < Laurence_b> I remember when channers trolled kiwifarms as being full of bored autistic housewives, didnt realise it was literally true
2022-10-05T14:34:09 < qyx> also future proofing, structs having required/optional members
2022-10-05T14:34:30 < qyx> that's not possible with packing everything in order, you would have to version it
2022-10-05T14:35:03 < jadew> my serialization library has versioning, but yeah, the optional bit is nice
2022-10-05T14:35:05 < qyx> json is ok too if you want readability, but other than than, json sucks in multiple different ways
2022-10-05T14:35:39 < qyx> ok, compared to your serialisation library, json or protobuf or cbor or whatever is much better
2022-10-05T14:35:57 < Laurence_b> >readability >when everything is on a computer
2022-10-05T14:35:58 < qyx> if the serialised blob is used as an API or protocol
2022-10-05T14:36:03 < Laurence_b> I never understood this meme
2022-10-05T14:36:16 < qyx> because I can parse json or protobuf with a single line of code and no unusual external dependency
2022-10-05T14:36:31 < Laurence_b> >oh wowz the binary data is in a certain format that can be put into ascii form
2022-10-05T14:36:32 < jadew> yeah, but this is not for external consumption
2022-10-05T14:36:39 < qyx> with anything custom you are creating a one more hassle
2022-10-05T14:36:48 < jadew> how so?
2022-10-05T14:36:51 < qyx> one more hassle whatever
2022-10-05T14:36:59 < jadew> I already have the library
2022-10-05T14:37:00 < Laurence_b> there are plenty of binary protocols
2022-10-05T14:37:09 < qyx> you have to maintain the library, your library is less tested, etc.
2022-10-05T14:37:26 < qyx> been there done that
2022-10-05T14:37:27 < jadew> it's plenty tested, and serialization isn't a big deal
2022-10-05T14:37:29 < qyx> never again
2022-10-05T14:37:29 < jadew> it's easy
2022-10-05T14:37:35 < qyx> no it is not
2022-10-05T14:37:43 < qyx> you will bite yourself
2022-10-05T14:37:59 < jadew> I've been doing it like this for more than a decade...
2022-10-05T14:38:07 < qyx> after years you will still encounter bugs
2022-10-05T14:38:16 < qyx> and you will be the one to fix them
2022-10-05T14:38:21 < jadew> never had issues, was just wondering if something can be improved
2022-10-05T14:38:35 < qyx> idk
2022-10-05T14:38:57 < qyx> if there are no extreme specifics you are dealing with, I would use anything standard
2022-10-05T14:39:01 < qyx> compared to my own creation
2022-10-05T14:39:32 < jadew> so would I, but the benefits don't seem to outweigh the cost in the case of protobuf
2022-10-05T14:39:40 < jadew> I don't want to deal with generators and crap like that\
2022-10-05T14:39:46 < jadew> my shit is literally one header file
2022-10-05T14:39:47 < qyx> so use cbor
2022-10-05T14:40:27 < qyx> or flatbuffers or what the new thing is

2022-10-05T14:43:20 < karlp> you pretty much did.
2022-10-05T14:43:21 < qyx> sorry I was gonna ask if he uses it to store data in his temperature logger
2022-10-05T14:43:22 < jadew> but switching to something else I have to deal with:
2022-10-05T14:43:29 < jadew> 1) Switching to something else.
2022-10-05T14:43:59 < jadew> 2) Adding a dependency and dealing with its requirements.
2022-10-05T14:44:07 < jadew> Benefits: --
2022-10-05T14:44:16 < karlp> do you have any issues right now?
2022-10-05T14:44:20 < jadew> no
2022-10-05T14:44:24 < karlp> problem solved then
2022-10-05T14:44:30 < karlp> back to the temperature logger then.
2022-10-05T14:44:35 < qyx> :D
2022-10-05T14:44:43 < jadew> very funny
2022-10-05T14:45:28 < jadew> I do have something I'm worrying about was kinda wondering if these libraries could address that issue, but probably not
2022-10-05T14:45:40 < qyx> you didn't mention the issue
2022-10-05T14:45:42 < jadew> *and was
2022-10-05T14:46:07 < karlp> can't mention the issue, as it exposes private better source 
2022-10-05T14:46:09 < jadew> it's not really an issue, I would like to have reliable connectivity, even if the connection goes down, device gets rebooted, etc
2022-10-05T14:46:43 < jadew> I'm about to write something to address that, but I was kinda hoping it was already addressed by other libraries
2022-10-05T14:46:54 < qyx> I am sure I understand
2022-10-05T14:47:09 < qyx> what does a serialisation library have to do with connection issues
2022-10-05T14:47:58 < jadew> IDK, they're part of the communication protocol, was hoping there's something in there to address this issue
2022-10-05T14:47:59 < karlp> jadew's monolithic ivory tower has everythign built in
2022-10-05T14:48:22 < jadew> simple data packers don't really offer much advantage over how things were done 20 years ago
2022-10-05T14:48:38 < jadew> (cuz we've been packing data for quite some time and we know how to do it already)
2022-10-05T14:49:44 < qyx> sorry, *I was not sure
2022-10-05T14:49:55 < qyx> but meh
2022-10-05T14:50:20 < qyx> have to do some shopping and another 400 m of cable is waiting for me on the drum
2022-10-05T14:55:00 < englishman> oh we have been packing alright
2022-10-05T15:41:57 < jadew> this is what my stuff looks like: https://pastebin.com/ukK7DMBt
2022-10-05T15:42:11 < jadew> it's inspired by boost serialize (I think)
2022-10-05T15:43:49 < jadew> would any of those libraries make my life better compared to what's there?

2022-10-05T21:49:50 < bitmask> so i guess it doesnt have to support copy constructible if you use std::move

2022-10-05T21:52:21 < rustyaxe> heh vidja games and scamcoin are a waste of computing resources that could be curing humanities problems :P

2022-10-05T21:53:38 < BrainDamage> you cannot put videogames and cryptocurrencies on the same level
2022-10-05T21:54:14 < BrainDamage> by that logic, unless you're solving world hunger you shouldn't do anything, and forget that humanity also needs entertainment
2022-10-05T21:55:23 < bitmask> yea that was a stupid statement :/
2022-10-05T21:55:27 < rustyaxe> its ok, were it not for humanities wasting all their resources to kill each other, we'd already be exploring the galaxy :o
2022-10-05T21:55:38 < rustyaxe> humanity's
2022-10-05T21:57:25 < jadew> PaulFertser, the guy compares it with C
2022-10-05T21:58:22 < jadew> other than assembly, I don't know what language would allow you to write leakier code than C
2022-10-05T21:58:48 < bitmask> at least c++ has utilities to to help prevent that stuff
2022-10-05T21:59:27 < bitmask> i dont think i have a single new keyword in my engine
2022-10-05T21:59:32 < jadew> ans smart pointers, so things get freed when they need to be freed, like the OP mentions
2022-10-05T22:01:09 < PaulFertser> jadew: of course. C++ doesn't have automatic ownership lifetime tracking though. And probably ensuring safe concurrency is harder. And despite all the efforts Rust is the first second language accepted by mainline Linux now.
2022-10-05T22:01:20 < jadew> PaulFertser, it does
2022-10-05T22:01:26 < jadew> shared_ptr
2022-10-05T22:02:01 < jadew> also, if you want concurrency safety there's boost's synchronized_value (possibly in STL now)
2022-10-05T22:02:02 < PaulFertser> That costs more than what Rust offers for the purpose.
2022-10-05T22:02:20 < jadew> how could it be done more efficiently?
2022-10-05T22:02:54 < rustyaxe> right a kernel in rust is interesting
2022-10-05T22:02:55 < jadew> it's just reference counting
2022-10-05T22:03:14 < rustyaxe> you lose a bit of stuff from the runtime that you can use, but its really quite pleasant to work with
2022-10-05T22:03:49 < rustyaxe> even dealing with x86 boot lunacy isnt that awful since you can still call into linked assembly in a sane way
2022-10-05T22:03:49 < PaulFertser> shared_ptr is doing runtime reference counting, https://rustc-dev-guide.rust-lang.org/borrow_check.html works compile-time
2022-10-05T22:04:51 < jadew> oh, that's the same with the move mechanism in c++
2022-10-05T22:05:16 < jadew> again... c++ has that by default as well
2022-10-05T22:05:47 < jadew> (the move constructors)
2022-10-05T22:06:22 < PaulFertser> Nothing prevents you from using a variable even after explicit std::move()
2022-10-05T22:06:42 < jadew> that's true
2022-10-05T22:08:20 < PaulFertser> Same about e.g. creating a lambda with [&] assigning it to some call back, leaving the scope, and then getting the callback called and using all the invalid references.

2022-10-05T22:18:27 < PaulFertser> I think it will give you a compile time error in that case. You'd need to be explicit about using something similar to shared_ptr.
2022-10-05T22:18:41 < jadew> I see
2022-10-05T22:19:51 < jadew> I wonder if new c++ compilers follow std::move and complain about accessing it afterwards - if they'd do that, it would be the same?
2022-10-05T22:24:08 < jadew> they don't

2022-10-06T12:13:00 < perdmann> Hi, i just started with STM32 and I decided to use MBED for a simple project. Is there a simple way or template to seperate user code and generated code? (For main its possible, but for Interrupt handlers?)
2022-10-06T12:15:58 < perdmann> I decided to not use freertos because the main loop will be enough. I just need a timer a button and a GPIO output.
2022-10-06T12:16:18 < jpa-> what generated code do you even need?
2022-10-06T12:17:01 < perdmann> jpa-: It configures the whole CPU, Clocks, the interrupt handler... Its nice to not do this by hand.
2022-10-06T12:18:17 < perdmann> And as I said, this is the first project with STM32, i plan to use it in other projects later on. 
2022-10-06T12:18:21 < jpa-> i would expect such code to go into a separate init function that you can just call
2022-10-06T12:19:32 < perdmann> I would expect that the generator generates the function prototype but not the implementation

2022-10-06T12:28:55 < karlp> didn't they say mbed?

2022-10-06T12:31:45 < jpa-> does mbed have some own generator?
2022-10-06T12:31:53 < jpa-> i though cube can generate some crap with mbed also
2022-10-06T12:36:12 < perdmann> Oh i thought that cubeMX thing is the generator in STM world to generate specific mbed "OS" ?

2022-10-06T13:32:38 < jpa-> i'm firmly in "just write the code yourself" camp
2022-10-06T13:32:47 < qyx> oh so your software quality acceptance level must be pretty low
2022-10-06T13:33:00 < jpa-> it is, but i live with it
2022-10-06T13:33:06 < qyx> I mean, perdmann's

2022-10-06T13:37:21 < jadew> clickety clack
2022-10-06T13:37:23 < perdmann> Oh it depends. My opinion about this is: DRY. I dont want to rewrite everything everytime again. So you link manually against the STM peripheral driver or also write these by yourself?
2022-10-06T13:39:42 < qyx> code generator sounds like code duplication
2022-10-06T13:39:48 < qyx> and code duplication sounds like something is wrong
2022-10-06T13:40:04 < perdmann> For example: I dont create my Linux Images from scratch, i use yocto for that... If there is something similar for STM32 i would use that. 
2022-10-06T13:40:30 < perdmann> qyx: ok so where do you put your drivers? Where did you get them from? 
2022-10-06T13:40:59 < qyx> for simple stuff I use libopencm3
2022-10-06T13:41:09 < qyx> for a bit less simple stuff freertos and libopencm3
2022-10-06T13:41:15 < qyx> not that it is ideal, but works
2022-10-06T13:41:30  * jadew never used drivers for stm32
2022-10-06T13:41:50 < jadew> and I was deeply dissatisfied with the shit generated by cube
2022-10-06T13:42:10 < jadew> but it's been a while since I touched any of that, so maybe it's different now
2022-10-06T13:42:20 < perdmann> jadew: dont use drivers basically means you write them by yourself?
2022-10-06T13:42:26 < jadew> yeah
2022-10-06T13:43:07 < qyx> you can use chibios with its hal, if you want
2022-10-06T13:43:13 < qyx> or stm32 cobe ecosystem with their middleware
2022-10-06T13:43:19 < qyx> or mbed
2022-10-06T13:43:41 < qyx> nuttx for adventurous people  liking posix
2022-10-06T13:43:58 < perdmann> jadew: so you configure DMA, IRQ, SPI and develop a abstract driver for that if you want to attach a SPI memory?
2022-10-06T13:44:17 < jadew> yes
2022-10-06T13:45:18 < jadew> I'm not opposed to using pre-generated or readily available drivers if they work well and are easy to use tho
2022-10-06T13:45:35 < jadew> otherwise, I would rather spend the time reading the reference manual and get exactly what I want
2022-10-06T13:46:09 < perdmann> Ok if I did this when i was studying, after that work is taking too much time.
2022-10-06T13:46:45 < perdmann> qyx: I really thought cubemx and mbed were related. I will try out mbed.
2022-10-06T13:48:24 < perdmann> I meant: I did this when i was studying. 
2022-10-06T13:49:23 < jadew> I would have done it the other way around, duct tape for school project, concrete for the actual house
2022-10-06T13:52:37 < perdmann> I dont believe that i can do better then code which is widely used. (But i do agree, that i should try to avoid bad generated code) 
2022-10-06T14:05:47 < Mangy_Dog> oh joy now im some what awake and trying to read this properly... i now realise why i struggled so hard last night with it... The english.... its sooooo broken https://www.hackster.io/javier-munoz-saez/all-pins-as-pwm-at-the-same-time-baremetal-stm32-1df86f
2022-10-06T14:08:51 < jpa-> lol, does it really rewrite the whole memory buffer when you change PWM value?
2022-10-06T14:09:07 < jpa-> and even does it per each pin
2022-10-06T14:09:41 < Mangy_Dog> i dont know
2022-10-06T14:09:41 < Mangy_Dog> yet
2022-10-06T14:09:57 < Mangy_Dog> im still trying to get my head around the concept and how i could impliment it with the core i use
2022-10-06T14:10:28 < jadew> what's so difficult about it? you're bitbanging pwm
2022-10-06T14:10:37 < Mangy_Dog> basically
2022-10-06T14:10:40 < Mangy_Dog> but using dma
2022-10-06T14:10:40 < jpa-> also a bit funny using 3 timers when they could just use 3 channels of a single timer
2022-10-06T14:11:18 < Mangy_Dog> but i dont know hal, and ive never actually directly used dma before... so im not exsactly sure how to do it :p
2022-10-06T14:12:18 < Mangy_Dog> but then i also need to figure out what timer i can use because im pretty sure some of the timers are tied to things the core uses
2022-10-06T14:12:31 < Mangy_Dog> and some of the hardware
2022-10-06T14:12:37 < Mangy_Dog> and i dont want to break serial or i2c
2022-10-06T14:12:50 < jpa-> ah, "core" in this case does not mean the CPU, but rather some crappy arduino-style software library you are using?
2022-10-06T14:12:59 < Mangy_Dog> yes
2022-10-06T14:13:02 < jpa-> fancy
2022-10-06T14:13:43 < Mangy_Dog> roger clarks thingy
2022-10-06T14:17:01 < Mangy_Dog> one thing i dont quite get
2022-10-06T14:17:27 < Mangy_Dog> its using three WORDS to hold the duty?
2022-10-06T14:17:32 < Mangy_Dog> but thats only 96 steps
2022-10-06T14:17:34 < Mangy_Dog> not 100
2022-10-06T14:17:46 < Mangy_Dog> he claims 100 steps in the duty
2022-10-06T14:18:06 < Mangy_Dog> unless hes truncating something and not really mentioning it
2022-10-06T14:20:07 < Mangy_Dog> also can dma access multiple pins and multple sets fo data at the same time?
2022-10-06T14:20:29 < jpa-> it's using one word per port per step
2022-10-06T14:20:54 < jpa-> gpioa / gpiob / gpioc
2022-10-06T14:21:21 < Mangy_Dog> oh ok
2022-10-06T14:34:02 < Mangy_Dog> so if i need 100 steps i need a 100 word array?
2022-10-06T14:37:13 < Mangy_Dog> for three ports thats 9600bits
2022-10-06T14:37:36 < Mangy_Dog> 1.2kb
2022-10-06T14:37:39 < Mangy_Dog> hmmmmmmm
2022-10-06T14:38:08 < Mangy_Dog> This hackyness is going on a C6... only 10KB ram :p
2022-10-06T14:42:04 < Mangy_Dog> well at least i understand what its actually doing now
2022-10-06T14:42:42 < Mangy_Dog> the bottom 16 bits of each... step... are the port values
2022-10-06T14:42:48 < Mangy_Dog> high low
2022-10-06T14:43:00 < Mangy_Dog> and its just constantly cycling that buffer
2022-10-06T14:43:04 < Mangy_Dog> in full
2022-10-06T14:43:29 < Mangy_Dog> and i just edit the value along the buffer 
2022-10-06T14:45:50 < jpa-> if you rewrite the whole buffer anyway and have no other GPIO stuff in the same port, you can also just write the 16-bit word, halving the memory use
2022-10-06T14:46:30 < Mangy_Dog> because the top 16 bits are identical?
2022-10-06T14:46:42 < Mangy_Dog> and can just append that at dma runtime?
2022-10-06T14:46:46 < jpa-> because you can write ODR instead of BSRR
2022-10-06T14:47:19 < Mangy_Dog> ODR?
2022-10-06T14:47:24 < Mangy_Dog> sorry thats a new one o nme
2022-10-06T14:47:29 < jpa-> GPIOx->ODR vs. GPIOx->BSRR
2022-10-06T14:48:47 < Mangy_Dog> canthe ODR be accessed byt he dma?
2022-10-06T14:49:31 < jpa-> sure
2022-10-06T14:49:48 < Mangy_Dog> soooo why was this guy saying use the BSRR?
2022-10-06T14:50:00 < Mangy_Dog> what was the implied bonus of that?
2022-10-06T14:50:21 < jpa-> you can have other gpio stuff on the same port
2022-10-06T14:51:09 < Mangy_Dog> ohhh so if im sharing the port with serial... use the bsrr
2022-10-06T14:51:17 < Mangy_Dog> so not to delete the hardwares data
2022-10-06T14:51:21 < jpa-> serial is not gpio, it is dedicated peripheral
2022-10-06T14:51:23 < Mangy_Dog> odr is more brute?
2022-10-06T14:51:30 < Mangy_Dog> i thought it shared ports
2022-10-06T14:51:34 < Mangy_Dog> iok
2022-10-06T14:51:40 < jpa-> you'll need a deep dive into the reference manual
2022-10-06T14:51:56 < Mangy_Dog> already got the datasheet open
2022-10-06T14:52:09 < jpa-> doesn't help when all the information is in the reference manual, not in the datasheet
2022-10-06T14:52:12 < jpa-> growing up with hardware hiding layers has pampered you
2022-10-06T14:52:27 < Mangy_Dog> i agree
2022-10-06T14:52:36 < Mangy_Dog> or hampered me
2022-10-06T14:52:36 < Mangy_Dog> :D
2022-10-06T14:52:58 < Mangy_Dog> certainly in the wanting to move away from sloeber side of things

2022-10-06T15:09:28 < Mangy_Dog> sooo gonna have to do bsrr
2022-10-06T15:09:43 < Mangy_Dog> got a button
2022-10-06T15:10:40 < jpa-> if you think about it, you'll realize that input is fine
2022-10-06T15:11:42 < Mangy_Dog> well that explains idr then
2022-10-06T15:13:18 < Mangy_Dog> so i guess the die, routes the pin to the IDR or ODR based on if its set to a in or out put
2022-10-06T15:13:31 < Mangy_Dog> so if set at input, any data set to the ODR is ignored on that pin
2022-10-06T15:13:52 < Mangy_Dog> i really need to get off my ssris :/ they really dont help me think
2022-10-06T15:22:31 < Mangy_Dog> one thing im not entirely sure about
2022-10-06T15:22:33 < Mangy_Dog> is what the timer is for
2022-10-06T15:22:42 < Mangy_Dog> if the dma is just cycling the buffer
2022-10-06T15:23:04 < srk> jadew: thanks for the tip :)
2022-10-06T15:23:23 < jpa-> Mangy_Dog: the timer triggers each dma transfer, so that they occur in regular intervals
2022-10-06T15:23:31 < Mangy_Dog> unless the timer is whats triggering the dma transfer, but how would the timer know when the dma has finished its buffer run?
2022-10-06T15:23:47 < jpa-> DMA transfers one word every time timer triggers
2022-10-06T15:24:06 < Mangy_Dog> hmm ok
2022-10-06T15:24:15 < jpa-> if you would free-run the transfer, the speed would depend on other load on the system bus
2022-10-06T15:24:25 < Mangy_Dog> but then still... how does the timer know when to trigger the dma? is there something in the dma that resets the timer?
2022-10-06T15:24:37 < jpa-> no, the timer just runs at its own frequency
2022-10-06T15:24:47 < jpa-> it can trigger the DMA e.g. once per microsecond
2022-10-06T15:25:01 < jpa-> and then you get PWM period of 100 microseconds if your DMA buffer is 100 words long
2022-10-06T15:25:46 < Mangy_Dog> oh is dma instantly fast then?
2022-10-06T15:25:59 < Mangy_Dog> so it would, fall out fo sync withg the timer?
2022-10-06T15:26:03 < Mangy_Dog> wouldnt
2022-10-06T15:26:13 < jpa-> DMA on STM32 takes about 6 cpu cycles
2022-10-06T15:26:24 < jpa-> you don't want to set the timer period faster than that
2022-10-06T15:26:31 < Mangy_Dog> ok
2022-10-06T15:27:25 < Mangy_Dog> i guess all i need to knwo now is what timer is safe to use on this "core"
2022-10-06T15:29:12 < jpa-> start debugger, check what timer clocks have been enabled in RCC
2022-10-06T15:29:28 < jpa-> (or even printf RCC registers to do the same)
2022-10-06T15:30:07 < Mangy_Dog> sighs, debugger isnt setup t the moment... had another nightmare with sloeber failing and had to reinstall it. 
2022-10-06T15:30:13 < Mangy_Dog> ill be doing that a little later
2022-10-06T15:30:29 < Mangy_Dog> id need to resetup openocd

2022-10-06T15:58:55 < witcher> as part of my uni class, i'm looking to develop for the STM32f429I-DISC1 without the use of STM32CubeIDE on Linux. can someone point me to a guide of how i would set this up with a build system like Make or Meson?
2022-10-06T15:59:56 < witcher> excuse me if I can't be more specific on what *exactly* i need -- the semester has just started and i'm not familiar with this! if you need more info to show me a guide or similar I'll ask again another time!
2022-10-06T16:02:48 < BrainDamage> you can look for example at libopencm3 example makefiles

2022-10-06T16:03:32 < BrainDamage> you'll also need linker infos with the memory boundaries for the specific chip you have
2022-10-06T16:03:38 < BrainDamage> eg https://github.com/libopencm3/libopencm3-examples/blob/master/examples/stm32/f1/stm32-h103/stm32-h103.ld

2022-10-07T02:53:52 < karlp> I'd rather just have visible flags on lcsc that "you can use this for assembly"
2022-10-07T02:57:38 < karlp> if the jlc parts page lists a price for 3000+ does thatm ean you can't use it for a 5 piece order?  the "help with ordering" says "you need 11"
2022-10-07T02:59:32 < catphish> i either 1) choose candidate parts elsewhere then type in the part numbers til one is available or 2) sort available parts by stock level to find the most generic ones
2022-10-07T02:59:56 < catphish> we'd all be happy if they had proper parametric searching but they do not
2022-10-07T03:00:40 < catphish> parametric works for passives, like if i want to choose the 1k 0402 resistor, it's fine, but otherwise no chance
2022-10-07T03:03:37 < karlp> yeah, but the jlc interface is even worse and flakier than lcsc's :|
2022-10-07T03:08:49 < catphish> yep
2022-10-07T03:10:02 < catphish> it's garbage, but what you gonna do? not use it? :D

2022-10-07T03:49:53 < karlp> well, it's my first time.
2022-10-07T03:50:40 < karlp> I've sent some assembly to china,anmd just gave them a bom, including lcsc and mouser and digikey part numbers, and they gave me very fair rates, but going to have a go at the jlc assembly for something personl, jsut to try it out
2022-10-07T03:52:33 < catphish> i use jlc for the simple reason that i don't want to bother with the back and forth with a human
2022-10-07T03:52:50 < catphish> i can just upload machine readable files and get a quote instantly
2022-10-07T03:53:02 < catphish> but it does mean extra work choosing available parts
2022-10-07T03:53:27 < catphish> basically, with my order volume, i assume "if you have to ask, you can't afford it"

2022-10-07T06:33:43 < jadew> because there's no intuitive way of doing it
2022-10-07T06:34:11 < jadew> and it involves writing the shortcut file yourself

2022-10-07T06:35:36 < jadew> if I double click on it, it complains that there's something wrong with it, if I right click -> edit, it opens the actual HTML of the page in the text editor...

2022-10-07T12:49:06 < jadew> I've done away with all of that anyway
2022-10-07T12:51:18 < Steffanx-> Yeah it's called dash. I didnt like it. I prefer a "dock". At the time I tried it the dash to Dock extension was so-so. Didn't try again yet
2022-10-07T12:51:43 < jadew> I'm using dash to panel
2022-10-07T12:51:46 < Steffanx-> It probably improved a lot
2022-10-07T12:52:06 < jadew> it looks a lot like windows 10 now

2022-10-07T14:01:47 < ventYl> these days pretty much everything looks like everything else
2022-10-07T14:01:57 < ventYl> to me KDE Plasma seems to be 1:1 with Windows 10
2022-10-07T14:02:08 < ventYl> the only difference is that you can turn off some of stupid behavior they have
2022-10-07T14:05:20 < jadew> ubuntu has a look of its own: stupid
2022-10-07T14:07:15 < jadew> it's good you can customize it (although, they're tirelessly working on changing that), but the customizations will never be as good as if they were part of the core thing
2022-10-07T14:11:12 < jadew> I've been using linux exclusively for most of this year
2022-10-07T14:11:15 < jadew> got used to it
2022-10-07T14:11:40 < jadew> when I hear a repeating beep from the other room, I know it crashed
2022-10-07T14:12:04 < jadew> when one of the monitors doesn't wake up, I ctrl + alt + F3 and then back to the UI one - that fixes it
2022-10-07T14:12:29 < jadew> when the microphone resets itself, alsamixer
2022-10-07T14:12:49 < ventYl> somehow, on my machine, there are bigger problem with running windows, than linux
2022-10-07T14:12:56 < ventYl> and it is pretty much off-the-shelf gaming PC
2022-10-07T14:13:07 < jadew> when the on-screen keyboard stops working - a virtual key is stuck
2022-10-07T14:14:30 < jadew> what goes wrong on windows?
2022-10-07T14:18:36 < jadew> currently my biggest annoyance is the streaming quality on amazon prime
2022-10-07T14:18:46 < jadew> can only watch rings of woke in SD
2022-10-07T14:20:15 < jadew> at times is like watching flip phone footage
2022-10-07T14:21:13 < Steffanx-> DRM crap?
2022-10-07T14:21:16 < jadew> yeah
2022-10-07T14:21:57 < jadew> I heard that media companies won't allow them to stream at higher quality
2022-10-07T14:22:22 < jadew> but they don't do that for amazon originals either so I don't know what to believe
2022-10-07T14:22:39 < ventYl> jadew: for some reason, front mic input is not recognized at all. In Linux it works out of box.
2022-10-07T14:23:56 < ventYl> another issue is that Windows disables wifi when turned off (but not when rebooted) in a way that radio cannot be found in linux afterwards and sometimes even windows doesn't find it
2022-10-07T14:24:43 < jadew> oh, I had issues like that with windows/linux reboot, but I don't remember with what
2022-10-07T14:24:52 < jadew> but windows worked every time
2022-10-07T14:25:10 < ventYl> another "issue" is that there are no drivers for my printer/scanner
2022-10-07T14:25:15 < jadew> it was linux that couldn't use whatever was broken after a windwos reboot
2022-10-07T14:25:23 < jadew> on windows?
2022-10-07T14:25:35 < ventYl> yes, i have to reboot into linux when I want to print or scan
2022-10-07T14:25:48 < jadew> I find that hard to believe
2022-10-07T14:25:51 < jadew> what printer do you have?
2022-10-07T14:26:16 < ventYl> same here. if windows fucks up the wifi, linux will detect the wifi, but won't find radio. once or twice even windows wasn't able to find it after boot
2022-10-07T14:26:57 < jadew> but see, that means that the linux driver isn't taking the correct steps to initialize it
2022-10-07T14:26:57 < ventYl> Canon MP280
2022-10-07T14:27:19 < ventYl> which is sad, because the driver was supplied by Intel itself
2022-10-07T14:27:26 < jadew> https://www.canon-europe.com/support/consumer_products/products/fax__multifunctionals/inkjet/pixma_mp_series/pixma_mp280.html?type=drivers&language=en&os=windows%2010%20(64-bit)
2022-10-07T14:27:39 < ventYl> I guess that it is not driver problem, rather UEFI/platform issue
2022-10-07T14:27:46 < ventYl> maybe something with power management
2022-10-07T14:28:02 < ventYl> I haven't disassembled DSDT to see how much garbage is in there
2022-10-07T14:28:13 < jadew> possibly, but if it works with one driver, then the other one is at fault
2022-10-07T14:28:31 < jadew> I found the driver for your printer
2022-10-07T14:28:49 < ventYl> well, it works like 90% with the other. i have mitigated the problem by sleeping the machine instead shutting it down. or if I shut it down, then I do it from linux
2022-10-07T14:29:12 < jadew> what wifi card is it?
2022-10-07T14:30:21 < ventYl> Intel AX200
2022-10-07T14:30:27 < ventYl> wifi6 + bt + ble
2022-10-07T14:30:32 < jadew> I think mine is intel as well
2022-10-07T14:30:58 < ventYl> the only intel-based piece of HW in this machine
2022-10-07T14:31:05 < ventYl> also the only piece of HW making trouble
2022-10-07T14:31:38 < jadew> maybe that's why their stock price is plummeting
2022-10-07T14:31:48 < jadew> shit wifi cards
2022-10-07T14:32:07 < ventYl> other than that it works ok
2022-10-07T14:32:22 < ventYl> I guess that their wifis are one of less fucked up products
2022-10-07T14:32:47 < ventYl> at least if compared to their GPUs and server CPUs
2022-10-07T14:33:30 < PaulFertser> ventYl: those cards' stability depends a lot on iwlwifi "ucode" version.
2022-10-07T14:34:23 < PaulFertser> Often times users see ucode mini-dumps in dmesg, and Intel devs sometimes pay attention to reports with that on kernel bugzilla.
2022-10-07T14:34:51 < ventYl> PaulFertser: plausible. this is first intel wifi I use after ~10 years. the previous one, I thrown away because it was overheating AF
2022-10-07T14:36:06 < jadew> it was only overheating if that wasn't the normal temperature it was running at :P
2022-10-07T14:36:38 < PaulFertser> ventYl: there's also a sick way to make them work as an AP on 5 GHz band: https://tildearrow.org/?p=post&month=7&year=2022&item=lar
2022-10-07T14:37:20 < ventYl> jadew: I used it as a hack replacement of original broadcom in my mac as that broadcom was of one very few, where there was almost no probability on making them work
2022-10-07T14:37:44 < ventYl> then I bought some atheros which was in the machine until I removed linux from it and returned mac os there
2022-10-07T14:38:25 < ventYl> PaulFertser: my interest of this wifi will vanish once I finish reconstruction of my house and introduce ethernet into this room
2022-10-07T14:38:31 < ventYl> so far so good, then I don't care
2022-10-07T14:39:09 < jadew> PaulFertser, the reason they disable 5G probably has to do with power ratings
2022-10-07T14:40:51 < jadew> that's usually the main difference between US and EU versions of wifi hardware
2022-10-07T14:41:07 < jadew> I don't know why it would work as a client tho
2022-10-07T14:41:36 < PaulFertser> jadew: no, they just do not market their cards as AP-capable, and to have easier time with regulatory they hardcode most of the restrictions in firmware (unlike proper cards that use Linux regulatory framework in a sane way).
2022-10-07T14:41:56 < jadew> I see
2022-10-07T14:42:02 < PaulFertser> jadew: so by default they're in "world regulatory domain" and have no-IR (initiated radiation) flag set on 5 GHz channels.
2022-10-07T14:48:11 < ventYl> guy from CZ NIC told me that pretty much the only wifi with not-fucked-up driver is some Mediatek something
2022-10-07T14:48:17 < ventYl> everything else sucks
2022-10-07T14:48:53 < karlp> well, mt76 has the most open drivers, 
2022-10-07T14:49:13 < Xogium> ventYl: he's about right, mediatek
2022-10-07T14:49:18 < Xogium> at least for usb wifi dongles
2022-10-07T14:49:22 < karlp> it's still totally a closed party, with a few devs having docs, but not really open still 
2022-10-07T14:50:30 < Xogium> karlp: yep agree, but at least the driver does not suck
2022-10-07T14:50:42 < Xogium> and its upstreamed
2022-10-07T14:52:24  * specing gave up on wifi long ago
2022-10-07T14:52:32 < specing> running cables everywhere is less painful in the long run
2022-10-07T14:52:48 < Xogium> specing: as long as you don't trip up on them ;p
2022-10-07T14:53:05 < specing> Xogium: they're neatly placed
2022-10-07T14:54:08 < ventYl> Xogium: he said basically that they still have some binary BLOB, but it only manages power management and something and everything else is outside in C
2022-10-07T14:54:11 < ventYl> unlike others
2022-10-07T14:54:41 < ventYl> but the talk wasn't really about this, so I didn't pay much attention. I've been just surprised because mediatek's SoCs suck, when it comes to linux support
2022-10-07T14:54:47 < ventYl> I had to sell my Gemini PDA due to this
2022-10-07T14:55:07 < Xogium> ventYl: yep they do. SoCs from mediatek are evil
2022-10-07T14:55:46 < karlp> that's a pretty sweeping statement :)
2022-10-07T14:56:04 < karlp> they have a _large_ lineup, they're probably no different badly supported than anyone else?
2022-10-07T14:56:47 < ventYl> IMO it depends, if SoC is targeted for mobile (=Android) or embedded (=Linux)
2022-10-07T14:57:16 < ventYl> SoC in question was mobile, used in PDA and with Linux, there was never any official Linux support planned
2022-10-07T14:57:42 < Xogium> routers SoCs are of course badly supported
2022-10-07T14:58:21 < ventYl> now I run combo of rockchip and allwinner, works for me
2022-10-07T14:58:38 < Xogium> allwinner ? That's odd
2022-10-07T14:59:00 < ventYl> yes, some crap 2 or 4 core shit, but good enough for Kodi
2022-10-07T14:59:12 < Xogium> ah yeah
2022-10-07T15:00:23 < PaulFertser> Xogium: mediatek router SoCs are nicely supported
2022-10-07T15:02:23 < ventYl> Xogium: anyway, regarding computing power, I am humble. It is not that long, I've been using PowerPC G4 and was happy with it
2022-10-07T15:02:40 < Xogium> PaulFertser: even in mainline?
2022-10-07T15:07:28 < PaulFertser> Xogium: OpenWrt is pretty close to mainline, and support is getting upstreamed steadily.
2022-10-07T15:10:13 < specing> ventYl: which is better supported ? rc or allwiner?
2022-10-07T15:10:43 < specing> I'm considering switching to an arm desktop next year or so
2022-10-07T15:11:22 < ventYl> specing: RC has some support, but not all of it is upstreamed. thus it is not perfect.
2022-10-07T15:11:45 < ventYl> the allwinner has way less Oomph, so I wouldn't consider it as candidate for desktop
2022-10-07T15:13:12 < ventYl> specing: I bought Pine64's rockpro64. I had old defunct iMac G5, stipped it of guts, cut display connector and soldered HDMI connector and it works. The only stuff which remains is to put together PSU which will power this thing as the original PSU died

2022-10-07T15:17:14 < ventYl> the successor supports
2022-10-07T15:17:21 < specing> rk3588 supports 32 GB
2022-10-07T15:17:33 < ventYl> ah ok, I have 33somethingsomething in there
2022-10-07T15:17:43 < ventYl> the one which is also in pinebook
2022-10-07T15:17:45 < ventYl> pro
2022-10-07T15:19:45 < specing> 3399?
2022-10-07T15:19:55 < ventYl> yeah
2022-10-07T15:20:08 < ventYl> quart64 has 3566, but can be obtained with 8GB RAM
2022-10-07T15:20:22 < ventYl> if it is "pin-compatible" with rockpro64, I will be able to swap it
2022-10-07T15:22:53 < ventYl> it seems that expensive bosch thermometer thingy is broken
2022-10-07T15:26:36 < Mangy_Dog> i really want some 3588 boards
2022-10-07T15:26:38 < Mangy_Dog> :/
2022-10-07T15:27:04 < Mangy_Dog> but theyre all hidiously over priced right now
2022-10-07T15:27:56 < ventYl> quartz can be obtained at ~100 EUR
2022-10-07T15:28:17 < ventYl> which is IMO not that bad given the price of parts
2022-10-07T15:29:36 < specing> that's not 3588 though
2022-10-07T15:29:45 < ventYl> ah, right
2022-10-07T15:29:56 < specing> Also I wish they'd finaly start supporting SO-DIMMs
2022-10-07T15:30:30 < ventYl> that's something which probably won't happen
2022-10-07T15:30:41 < ventYl> it rises costs and engineering effort a lot
2022-10-07T15:31:08 < ventYl> as you have to write bootloaders which are able to train DDRs of various types, buy connectors, etc.
2022-10-07T15:31:31 < ventYl> it would raise price tag substantially
2022-10-07T15:33:57 < specing> ah ok
2022-10-07T15:34:16 < specing> why aren't there cheap x86 boards with soldered ram common, then?
2022-10-07T15:36:24 < ventYl> the DDR train functionality is probably already part of platform code obtained from CPU / chipset manufacturer, so you don't have to deal with it. and the cost of designing such solution is absorbed in large amount of pieces produced
2022-10-07T15:37:00 < ventYl> PaulFertser probably knows more about it. I only know a bit from presentation guys from Fujitsu-Siemens gave us
2022-10-07T15:39:42 < specing> ventYl: still lots of connectors to buy
2022-10-07T15:39:55 < PaulFertser> I think for Intel processors the DDR training is part of the closed source FSP, yes.
2022-10-07T15:40:25 < ventYl> specing: costs for connectors fall dramatically once you buy millions of them
2022-10-07T15:40:53 < specing> ventYl: costs is probably about there at thousands already
2022-10-07T15:41:40 < ventYl> specing: but I doubt anyone will be able to produce such HW in thousands
2022-10-07T15:41:59 < ventYl> even Pine's HW is produced at ~1200 per batch
2022-10-07T15:42:23 < specing> two sodimm slots per hardware is thousands :D
2022-10-07T15:42:31 < specing> or idk how many channels these ARMs have
2022-10-07T15:42:33 < specing> 2?
2022-10-07T15:43:07 < ventYl> I'd guess they only have LPDDR support
2022-10-07T15:47:23 < specing> These things have a lot of cores and a GPU, it's got to need a lot of RAM bandwith
2022-10-07T15:47:29 < specing> bandwidth*
2022-10-07T15:49:52 < ventYl> it doesn't have that much of it. RK3399 in PBP has like 1/10 of 1st gen i3 bandwidth
2022-10-07T15:50:02 < ventYl> or maybe even less
2022-10-07T15:50:31 < ventYl> effectively, just displaying static 4k image consumes 50% of memory bandwidth
2022-10-07T15:51:22 < specing> :O
2022-10-07T15:51:55 < specing> well idk then, but according to geekbench the rk3588 outperforms my 3rd gen i5 so
2022-10-07T15:52:04 < specing> (desktop)
2022-10-07T15:52:15 < specing> suspicious results but hey
2022-10-07T15:52:28 < ventYl> maybe the benchmark in question can be fit into L2 cache or is not memory bandwidth bound
2022-10-07T15:52:47 < ventYl> also, maybe 3588 has increased bandwidth
2022-10-07T15:53:58 < specing> these boards are tiny so maybe someday some will fit into this thinkpad case
2022-10-07T15:54:03 < specing> that'd be pretty sweet :)
2022-10-07T15:54:33 < ventYl> the biggest issue is display connection
2022-10-07T15:54:41 < ventYl> that's why I fitted rockpro into iMac
2022-10-07T15:54:51 < karlp> anyone here experimented with how fast you can get DFU to go?
2022-10-07T15:55:06 < specing> ventYl: yeah, needs LVDS for this thing
2022-10-07T15:55:10 < karlp> it's capped at 4k transfer sizes on windows/linux because it's a control transfer,
2022-10-07T15:55:16 < ventYl> iMacs of that era (G5 and early intels) use panels which have HDMI PHY rather than plain LVDS
2022-10-07T15:55:22 < specing> but there's eDP to LVDS converters, and probably also HDMI to LVDS
2022-10-07T15:55:24 < specing> but idk
2022-10-07T15:55:36 < karlp> I'm getting ~1.2MB/sec, which is .. ok, but compared to usb mass storage, which gives ~9-10MB/sec it's kinda shit?
2022-10-07T15:55:37 < ventYl> so it was all just a matter of stripping the old mobo connector and soldering HDMI connector
2022-10-07T15:57:03 < ventYl> karlp: isn't the difference coming from the fact that DFU doesn't use `bulk` transfer mode? (IDK if it does though)
2022-10-07T15:57:24 < karlp> that's what I suspect, yeah, that the control transfer mechanism in4k chunks means I'm probably "at the limit" alreadyd
2022-10-07T15:57:39 < karlp> just wondering if someone "knows" that, or whether I've got to and do maths and shit and try and figure it out

2022-10-07T16:04:17 < Laurence_b> hi, anyone here know how to read hex out of netcat?
2022-10-07T16:05:16 < ventYl> again, you are trying to do somethin stupid?
2022-10-07T16:05:27 < ventYl> is that your "telemetry" again?
2022-10-07T16:06:11 < Laurence_b> hmm
2022-10-07T16:06:19 < Laurence_b> xxd -p with a timeout seems to do it
2022-10-07T16:06:22 < Laurence_b> yeah
2022-10-07T16:07:10 < ventYl> somehow I don't understand why are you gluing it together from trash rather than writing something at least half-proper
2022-10-07T16:07:14 < karlp> right, yeah, there's no bwPolltimeouts being used, this is as fast as it goes then...
2022-10-07T16:07:59 < ventYl> karlp: as fast as hardware/firmware goes, or as fast as protocol goes?
2022-10-07T16:08:14 < karlp> as fast as protocol goes I imagine.
2022-10-07T16:09:23 < specing> Laurence_b: billion dollar high-tech, controlled by 1960s tech, is it?
2022-10-07T16:09:34 < Laurence_b> yes
2022-10-07T16:09:52 < Laurence_b> 19inch rack mount stuff
2022-10-07T16:10:35 < specing> you need to do better
2022-10-07T16:10:45 < specing> wifi control and then make tricorders to control it
2022-10-07T16:11:17 < ventYl> everything that moves is controlled by ancient tech
2022-10-07T16:11:20 < karlp> even just putting uboot into the ram backend, so theres "zero" waiting for flash, it's exactly same speed.
2022-10-07T16:11:39 < karlp> so yeah, ~1.3MB/sec is about the top of DFU.
2022-10-07T16:13:18 < ventYl> self-driving cars are a desperate attempt to mount non-functional prototype of photon torpedo launcher onto chassis of VW bug with analogue engine control unit and Phosphorus direct injection
2022-10-07T16:15:57 < karlp> huh, lol. I filed an issue with libusb 7 years ago about why they have this limitation on 4k...
2022-10-07T16:17:49 < specing> ventYl: wat.jpg
2022-10-07T16:18:31 < Laurence_b> hmm how do I send data with netcat?
2022-10-07T16:18:45 < Laurence_b>  echo -e -n '\x04\x58\x16\x00\x20\x20\x30\x31\x32\x00' | nc -u localhost 1251
2022-10-07T16:18:49 < Laurence_b> ^that does nothing
2022-10-07T16:20:39 < karlp> nc blah < (echo hoho) ?
2022-10-07T16:21:12 < karlp> oh, -q1?
2022-10-07T16:21:21 < karlp> there's netcat versions with... rather different command line interfaces
2022-10-07T16:21:52 < karlp> or, echo blah | nc -N host port 
2022-10-07T16:22:16 < Laurence_b> hmm /dev/udp works ok
2022-10-07T16:22:27 < karlp> its probably sitting there waiting for somethign without the -N 
2022-10-07T16:23:07 < karlp> I've also heard of things like nc exiting before it's drained stdin...
2022-10-07T16:23:34 < karlp> (or use socat which has less incompatible versions around, and does all the same shit)
2022-10-07T16:26:25 < ventYl> specing: large portion of SW developers in automotive are really old-school guys incapable of working with anything at least modular
2022-10-07T16:26:51 < ventYl> there is modular paradigm for automotive for at least 20 years, but it successfully exploited in a way, that everything is still essentailly monolithic
2022-10-07T16:27:01 < ventYl> just to make these guys feel comfortable
2022-10-07T16:27:23 < ventYl> it causes all kinds of troubles, delays, fuckups, recalls, but nevermind, carps feel comfortable
2022-10-07T16:27:32 < Laurence_b> hmm ok I can send to port 1255 but not port 1251
2022-10-07T16:27:38 < Laurence_b> but there is no error
2022-10-07T16:27:53 < Laurence_b>  sudo echo -e -n '\x04\x58\x16\x00\x20\x20\x30\x31\x32\x00' > /dev/udp/127.0.0.1/1251
2022-10-07T16:28:01 < ventYl> yet, this approach fails miserably if you want to introduce ADAS, things *have* to be modular
2022-10-07T16:28:08 < Laurence_b> should that work even if root owns the port?
2022-10-07T16:28:11 < ventYl> and here is the place where shit hit the fan
2022-10-07T16:30:18 < Laurence_b> actually I might be being blocked by iptables, confusing
2022-10-07T16:33:56 < karlp> is "carps" the industry slang for greybeards or something?
2022-10-07T16:34:04 < Laurence_b> hmm wtf
2022-10-07T16:34:18 < Laurence_b> my c code can send on 1251, but /dev/udp fails

2022-10-07T16:36:02 < Laurence_b> redirect logic is triggered by /dev/udp but not a c program using a socket

2022-10-07T16:46:26 < ventYl> karlp: "carps" is my slang for people who oppose any change for "historic reasons" i.e. because it would make them obsolete and/or they would have to learn something fundamentally new
2022-10-07T16:49:01 < Laurence_b> hmm looks like it might be easier just to physiclly haxor these modules
2022-10-07T16:49:14 < Laurence_b> they just echo rs485 to ethernet so shouldnt be too hard

2022-10-07T16:51:00 < Laurence_b> wait I know, I could add extra iptables rules to mark then redirect packets sent to a "haxor port", then I will be able to inject fake rs485 packets through the firewall

2022-10-07T19:30:22 < perdmann> Hi, today i received a small eval board with a STM32F103C8T6. I want to program it with a Olimex ARM - USB - TINY. I only connected GND, 3.3V, SWCLK and SWDIO. These are the only ones which are available to me. It is not working for me, i get several openocd errors
2022-10-07T19:36:43 < jpa-> perdmann: i assume you have the special adapter that ARM-USB-TINY needs for SWD support?
2022-10-07T19:40:09 < perdmann> jpa-: no i dont have any adapter
2022-10-07T19:40:34 < perdmann> it looks like there is communication: Error: stm32f1x.cpu: IR capture error; saw 0x0f not 0x01
2022-10-07T19:41:33 < jpa-> according to arm-usb-tiny manual it only supports jtag without adapter, you need some external resistors for SWD
2022-10-07T19:42:08 < perdmann> :/

2022-10-07T19:43:25 < jpa-> why aren't you just using STM32 discovery or nucleo boards like everybody?

2022-10-07T20:43:12 < Steffanx-> i suspect you are this spy, rustyaxe 
2022-10-07T20:43:22 < specing> lol
2022-10-07T20:43:56 < tomeaton17> I work in defence so I will leave it at that
2022-10-07T20:44:05 < Steffanx-> We all report to Rob. Rob235 aka bitmask 
2022-10-07T20:44:25 < specing> tomeaton17: killer robots is it?
2022-10-07T20:44:27 < Steffanx-> When we feed him too much shit he will puke.
2022-10-07T20:44:43 < rustyaxe> damnit
2022-10-07T20:44:52 < rustyaxe> i left my gun in the cubicle again, bbiab
2022-10-07T20:44:53 < tomeaton17> Lol I can neither confirm nor deny that
2022-10-07T20:45:18 < specing> killer robots confirmed
2022-10-07T20:45:23 < bitmask> uhh wha?
2022-10-07T20:45:29 < Steffanx-> Aer you a true redneck rustyaxe ?
2022-10-07T20:45:37 < tomeaton17> hah sounds like a fun project
2022-10-07T20:46:28 < tomeaton17> I'm trying to convince company to buy a keysight uxr
2022-10-07T20:46:30 < Steffanx-> Should you be using stm32 if you actually want to manufacture those bots?
2022-10-07T20:47:17 < tomeaton17> We usually operate at low TRL
2022-10-07T20:47:29 < tomeaton17> So thats the clients problem
2022-10-07T20:47:34 < PaulFertser> russians used stm32 in war things, why shouldn't british do?
2022-10-07T20:48:07 < ventYl> russians used whatever they can get their hands on in war things
2022-10-07T20:48:15 < ventYl> even museum items
2022-10-07T20:48:46 < ventYl> PaulFertser: btw, did you (manage to) leave?
2022-10-07T20:49:01 < PaulFertser> ventYl: have you read that report? I do not remember any museum age things mentioned.
2022-10-07T20:49:17 < PaulFertser> ventYl: not yet :/
2022-10-07T20:49:55 < ventYl> PaulFertser: what report? I've only seen some T-62s which broke in Ukraine and were vacated by the crews
2022-10-07T20:51:21 < ventYl> this summer I've been around some outdoor WW2 museums, those T-34 smell as if there were still engines inside and the whole thing was basically functional after certain effort

2022-10-07T21:10:07 < \dev\ice> good article
2022-10-07T21:10:30 < \dev\ice> i think they will move to riscv in the future
2022-10-07T21:12:40 < PaulFertser> Several russian companies already have Cortex-M0/1/3 cores source codes (enough to implement in any ASIC) so why would they bother?
2022-10-07T21:13:05 < PaulFertser> Cortex-A<something> too
2022-10-07T21:19:29 < specing> PaulFertser: because it's going to be impossible to license new stuff
2022-10-07T21:19:34 < specing> so better move to risc-v asap
2022-10-07T21:20:15 < PaulFertser> specing: in the case russia is not forcefully demilitarised, you think anyone there is going to care about licensing?
2022-10-07T21:20:36 < specing> PaulFertser: ah right
2022-10-07T21:20:39 < specing> fair enough
2022-10-07T21:23:37 < \dev\ice> having riscv as your mcu/cpu - is much easier to manufacture
2022-10-07T21:23:44 < \dev\ice> i mean find where to
2022-10-07T21:23:47 < \dev\ice> o
2022-10-07T21:24:04 < \dev\ice> sw side too 
2022-10-07T21:24:20 < \dev\ice> same reason they looked into reactOS
2022-10-07T21:24:36 < \dev\ice> or n korea has "national linux"
2022-10-07T21:25:31 < PaulFertser> https://riscv.org/news/2019/12/yadro-takes-control-of-russian-risc-v-startup-peter-clarke-eenews-europe/ but that was long before the war
2022-10-07T21:26:00 < specing> Does russia have domestic manufacture capabilities? And which noes?
2022-10-07T21:26:03 < specing> nodes*
2022-10-07T21:26:17 < \dev\ice> i think they have some
2022-10-07T21:27:18 < \dev\ice> aj, looked at VLIW history
2022-10-07T21:27:22 < \dev\ice> seems outside
2022-10-07T21:27:32 < \dev\ice> The Elbrus 2000 (Russian: Эльбрус 2000) and its successors are Russian 512-bit wide VLIW microprocessors developed by Moscow Center of SPARC Technologies (MCST) and fabricated by TSMC. 
2022-10-07T21:27:33 < PaulFertser> specing: https://ru.wikipedia.org/wiki/%D0%A1%D0%BF%D0%B8%D1%81%D0%BE%D0%BA_%D0%BC%D0%B8%D0%BA%D1%80%D0%BE%D1%8D%D0%BB%D0%B5%D0%BA%D1%82%D1%80%D0%BE%D0%BD%D0%BD%D1%8B%D1%85_%D0%BF%D1%80%D0%BE%D0%B8%D0%B7%D0%B2%D0%BE%D0%B4%D1%81%D1%82%D0%B2#%D0%92_%D0%A0%D0%BE%D1%81%D1%81%D0%B8%D0%B8_%D0%B8_%D0%A1%D0%9D%D0%93
2022-10-07T21:28:34 < PaulFertser> It might be they have resources to get down to 90 nm with reasonable yield.
2022-10-07T21:28:58 < rustyaxe> 512 bit words? wtf
2022-10-07T21:29:19 < PaulFertser> btw, plenty of illegal Cortex-M MCU clones are getting manufactured in China, so probably licensing can be "workarounded" sometimes.
2022-10-07T21:29:52 < \dev\ice> 90 nm for mil, even space, is good enought
2022-10-07T21:35:53 < PaulFertser> \dev\ice: you know that DPRK Linux adds unique computer fingerprints to each document you view, so if it ever gets in the hands of authorities they could trace it back though the distribution chain?
2022-10-07T21:39:51 < specing> \dev\ice: yep
2022-10-07T21:41:34 < \dev\ice> PaulFertser: i didnt
2022-10-07T21:42:49 < PaulFertser> Guess their AOSP variant has similar "feature".
2022-10-07T21:43:39 < PaulFertser> Can't imagine russia degrading to DPRK-style state. Iran-like seems possible though.
2022-10-07T21:50:59 < specing> aren't they already iran-like?

But Joseph sent us all a powerful message.  “Just let it go, man,” was the chunky lesson we needed in these stressful times. Donald Trump, in an effort to be viewed as a ‘macho man’, would have totally held it in.

2022-10-08T01:07:05 < karlp> lol, $60 for pcb assembly.  $20 for shipping (in that $60) and $18 of what's left is the setup charges per unique component.  actually pcb and assembly and parts are sooo cheap.
2022-10-08T01:07:22 < karlp> glad I used 2x10k instead of 5.1k resistors :)
2022-10-08T01:35:12 < Steffanx-> jlcpcb shipping $20?!
2022-10-08T01:36:03 < Steffanx-> have some 2x6cm 4 layer pcb and shipping alone is over that $20 :S

2022-10-08T23:08:23 < Laurence_b> we are building derivative unit for TGV
2022-10-08T23:09:00 < Laurence_b> axel seals will probably be rubber seals onto beryllium copper with oil header tank
2022-10-08T23:09:44 < kaki> why beryllium?
2022-10-08T23:10:42 < kaki> werent some seals your problem like a month ago?
2022-10-08T23:11:16 < Steffanx-> navy seals maybe.

2022-10-08T23:49:51 < BrainDamage> now I wonder if you shave it enough if you get the equivalent of beryllium oxide dust
2022-10-08T23:58:55 < kaki> they make non-spark tools from beryllium-copper

2022-10-09T00:38:01 < kaki> thanks lurencer
2022-10-09T00:44:11 < karlp> TIL about samsung "land side capacitors"
2022-10-09T00:46:47 < kaki> same thing than on board capacitors?
2022-10-09T00:49:52 < karlp> caps that are like 0.1mm thick and lower, designed for going _between_ a bga and the board itself...

2022-10-09T00:51:01 < karlp> so 0402, but 0.1 high instead of ~0.4 or more.
2022-10-09T00:51:06 < kaki> tiny caps
2022-10-09T00:51:35 < karlp> (samsgun cl "regular" 0402 are availabel in heighs of 0.2 throgh 0.7
2022-10-09T00:51:43 < kaki> anything else astounishing about them than the size?
2022-10-09T00:52:27 < karlp> nah, j ust the idea of mountingin underneath bga/lga components was new to me :)
2022-10-09T00:52:34 < kaki> volumetric capacity? materials?
2022-10-09T00:53:55 < kaki> i have not seen any yet inside bga ballgrid
2022-10-09T00:54:07 < kaki> not that I have looked

2022-10-09T00:56:11 < qyx> maybe?
2022-10-09T00:56:28 < qyx> the idea is quite old
2022-10-09T00:56:31 < karlp> so, I've found errors on my usb board, before I've even started assembling, that would be ~easy to fix with greenwire, and stacking some parts, or do I just review it again and eat the board cost?
2022-10-09T00:57:05 < karlp> yeah I'd just not seen caps labelled for it explicitly.
2022-10-09T00:57:57 < karlp> heh, new arrivals on lcsc: https://lcsc.com/product-detail/New-Arrivals_deli-6970914820008_C3020009.html
2022-10-09T00:58:38 < qyx> I have found a new ADC now when I already have one working design and two PCBs waiting to be assembled
2022-10-09T00:58:55 < qyx> so, maybe eating the board makes sense
2022-10-09T00:59:00 < qyx> I mean, the cost of it
2022-10-09T00:59:33 < karlp> also, usb2517 are back in stock in many hundreds on lcsc, so not even needing to hoard the parts right now..
2022-10-09T00:59:45 < karlp> but I have _way_ too many bom items to ask themt o make it...

2022-10-09T20:15:04 < specing> it was probably someone smoking in a non-smoking area on the bridge

2022-10-09T20:39:04 < ventYl> also, poles around are not stripped off, even if it was majestic explosion, which suggests that it came from underneath

I don't see condition variables in freertos documentation, does anyone know a better pattern for tasks to communicate readiness than spinning on reading a global?

2022-10-11T08:01:41 < jpa-> begriffs: event groups will work for the purpose also
2022-10-11T08:01:59 < jpa-> or if it is a single task, xTaskNotify()
2022-10-11T08:03:21 < jpa-> but in reality, taskyield() for waiting for initialization seems just fine for me, unless you need realtime constraints for initialization

2022-10-11T17:10:29 < Sadale> I think it was hacked like a week ago or so
2022-10-11T17:15:17 < qyx> oh no
2022-10-11T17:17:03 < bitmask> im so sorry that im a week late
2022-10-11T17:17:05 < rustyaxe> after the ps3 fiasco? I've not and will never buy another sony product. We specifically bought our ps3 because it was sony's suggestion for how to play german ps1/ps2 games in the USA.
2022-10-11T17:17:25 < rustyaxe> Then they disable backwards compatibility.. which was present IN HARDWARE in the model i had in a software update
2022-10-11T17:17:26 < bitmask> i'll only buy a console if its moddable
2022-10-11T17:17:47 < Sadale> raspberry pi
2022-10-11T17:17:59 < Sadale> screw it. Just buy a PC.
2022-10-11T17:18:00 < rustyaxe> i wont buy sony products period, but i havent touched a video game in...at least 1.5 decades :P
2022-10-11T17:18:09 < rustyaxe> just lost interest in them
2022-10-11T17:18:48 < bitmask> yea i almost never play games, im more interested in making them
2022-10-11T17:18:50 < rustyaxe> between my rage over us owning literally hundreds of useless games (we ended up importing a german ps2 in the end at a cost about equal to a ps3 all said and done)
2022-10-11T17:18:57 < bitmask> although i have no good game ideas
2022-10-11T17:18:59 < rustyaxe> and just idk something changed and they got boring as hell? :P
2022-10-11T17:19:00 < bitmask> so im just working on an engine
2022-10-11T17:19:10 < Sadale> lol I actually finished a couple of games long time ago.
2022-10-11T17:19:13 < rustyaxe> make a game you go around and rob drug dealers while dressed as fake cops
2022-10-11T17:19:19 < rustyaxe> :p
2022-10-11T17:19:24 < rustyaxe> like dopewars but graphical
2022-10-11T17:19:27 < Sadale> In one of the games you're a bird that's paid to poop on people
2022-10-11T17:21:39 < srk> I've managed to get couple of ps1/ps2 games running with retroarch recently, just had to grab some BIOSes from internetz
2022-10-11T17:22:22 < rustyaxe> srk: this was years ago, i do not even have that same wife anymore :P
2022-10-11T17:22:27 < bitmask> I have a pretty nice emu/rom collection
2022-10-11T17:22:39 < rustyaxe> i switched from german to chinese
2022-10-11T17:23:12 < bitmask> id like to try some of the newer system emulators but my 'gaming htpc' as i call it is pretty old
2022-10-11T17:23:15 < rustyaxe> firmware's a little buggy sometimes, but definitely an upgrade either way
2022-10-11T17:23:32 < bitmask> only has a 980
2022-10-11T17:23:52 < rustyaxe> a what?
2022-10-11T17:24:23 < bitmask> graphics card, nividia geforce gtx 980 or something like that
2022-10-11T17:24:46 < rustyaxe> i see
2022-10-11T17:25:24 < bitmask> looks like it came out in 2014
2022-10-11T17:25:31 < bitmask> so thats when i got it
2022-10-11T17:25:46 < bitmask> old
2022-10-11T17:27:06 < srk> plenty for PS :)
2022-10-11T17:29:12 < srk> this is impressive tho https://www.youtube.com/watch?v=fnorDYd0JQc but I can't reproduce :D
2022-10-11T17:29:27 < rustyaxe> now if only we could take all those computing resources and electricities used for vidja games..and use them to do something that would actually cure human sufferings :o
2022-10-11T17:29:40 < srk> retroarch has bunch of interesting shaders to improve the quality of the old games
2022-10-11T17:31:32 < bitmask> are you really saying that AGAIN rustyaxe 
2022-10-11T17:34:03 < karlp> we'll, they've already opened their mouth and proved things about themselves, hardly surprising they'd keep doing it..
2022-10-11T17:36:31 < jpa-> it's not weird to overgrow video games, but demanding that all human activity should be focused on some altruistic goal is just silly
2022-10-11T17:40:50 < BrainDamage> what's more weird is the obsession with video games, as if it was the only entertainment activity
2022-10-11T17:41:09 < BrainDamage> vs movies, car racing, etc etc
2022-10-11T17:41:36 < srk> fpv racing!

2022-10-11T17:52:19 < jpa-> so you sell laggy internet connections and resolve it by selling extra fake bandwidth that does not actually resolve the latency?
2022-10-11T17:52:28 < jpa-> sounds like very useful activity

But they KNOW they need at least gigabit fiber so their brat kids will stop crying about losing in their vidja games :P

2022-10-11T20:45:15 < bitmask> fuck i feel terrible, i dont think i can take anymore methadone either
2022-10-11T20:50:41 < kaki> speed?
2022-10-11T20:53:22 < kaki> you had chrons?
2022-10-11T20:59:09 < Steffanx-> Don't do that bitmask 
2022-10-11T20:59:32 < bitmask> had? have
2022-10-11T20:59:50 < bitmask> Steffanx- i wont, i took enough
2022-10-11T21:00:41 < Steffanx-> I mean the dont feel bad. The methadone... yeah idk 😋
2022-10-11T21:01:00 < bitmask> ohh, yea cause i have a choice hah
2022-10-11T21:01:56 < bitmask> I think exercising is helping though. I just went to get blood drawn and usually its a whole thing and it was nice and easy this time
2022-10-11T21:02:08 < Steffanx-> Always a choice. Luckily I don't have to make this one 
2022-10-11T21:02:16 < Steffanx-> Theres*
2022-10-11T21:03:09 < Steffanx-> When I hear how mr mwk goes crazy when he's out of methadone...... 
2022-10-11T21:03:33 < bitmask> is he on a program or does he get it illegally? 
2022-10-11T21:03:57 < Steffanx-> Both? I guess
2022-10-11T21:03:59 < bitmask> does he just not take it as he should so he runs out? 
2022-10-11T21:04:22 < Steffanx-> Heh idk. My mawk knows 
2022-10-11T21:04:53 < mawk> I kind increased the dose a little bit by mistake
2022-10-11T21:04:58 < mawk> I'm prescribed 120mg
2022-10-11T21:05:05 < mawk> and I'm taking around 450mg 
2022-10-11T21:05:11 < Steffanx-> Mr. Not my.
2022-10-11T21:05:17 < mawk> I stopped keeping track of it to not scare myself
2022-10-11T21:05:31 < Steffanx-> A little. Yeah..
2022-10-11T21:05:31 < bitmask> I take extra on tuesdays (the day I go to pick it up)  and less on monday. I may take slightly more/less on other days but not as much as mon/tues I actually like taking less on monday which is why i continue to do it. it gives me a day to poop even if I dont feel as good
2022-10-11T21:05:35 < mawk> I just pop them pills and forget about it
2022-10-11T21:05:55 < bitmask> wtf 450?
2022-10-11T21:05:55 < mawk> you need 350mg to kill a horse
2022-10-11T21:05:59 < mawk> I'm stronger than a horse
2022-10-11T21:06:02 < mawk> yeah
2022-10-11T21:06:05 < mawk> it's tolerance 
2022-10-11T21:06:05 < bitmask> why 
2022-10-11T21:06:11 < bitmask> thats kinda dumb
2022-10-11T21:06:19 < mawk> why
2022-10-11T21:06:27 < mawk> it doesn't feel good at lower doses anymore 
2022-10-11T21:06:29 < bitmask> its gonna take forever to get off
2022-10-11T21:06:31 < mawk> so I have to increase 
2022-10-11T21:06:37 < mawk> maybe
2022-10-11T21:06:42 < bitmask> I only take 37mg
2022-10-11T21:06:46 < mawk> decreasing from 450 to 120 isn't that hard
2022-10-11T21:06:50 < mawk> the last mgs are the hardest
2022-10-11T21:06:54 < mawk> like from 20 to 0
2022-10-11T21:06:56 < bitmask> true but still
2022-10-11T21:07:03 < Steffanx-> The difference is.. you want to stop, mawk doesn't, bitmask ?
2022-10-11T21:07:04 < bitmask> i never heard of anyone taking more than like 160 or 200
2022-10-11T21:07:09 < mawk> currently I'm on 120 since 3 days and I have only very minor wd
2022-10-11T21:07:13 < mawk> just some insomnia 
2022-10-11T21:07:38 < mawk> when I take too much my vision blurs
2022-10-11T21:07:49 < mawk> I wonder if my heart is okay
2022-10-11T21:07:53 < mawk> with that long QT thing
2022-10-11T21:07:58 < mawk> I need BrainDamage to diagnose me
2022-10-11T21:08:00 < Steffanx-> Is your brain OK?
2022-10-11T21:08:02 < bitmask> i do wonder if I could stop. I dont want to keep taking it but I also do. I really have to because of my stomach though
2022-10-11T21:08:18 < mawk> brain is fine 
2022-10-11T21:08:28 < bitmask> yea you should get your heart checked at least once a year
2022-10-11T21:08:49 < Steffanx-> Health care probably makes it free anyway  mawk
2022-10-11T21:08:56 < bitmask> I got mine checked shortly after I started and a year later and not since but im on a low dosage
2022-10-11T21:09:05 < mawk> but I heard the QT thing is bs
2022-10-11T21:09:10 < bitmask> really?
2022-10-11T21:09:11 < bitmask> why
2022-10-11T21:09:11 < mawk> pushed by a concurrent lab of methadone
2022-10-11T21:09:17 < mawk> by buprenorphine manufacturer
2022-10-11T21:09:21 < mawk> to push for their own treatment 
2022-10-11T21:09:36 < Steffanx-> What's QT? I know QuickTime, but.. 
2022-10-11T21:09:40 < bitmask> well it only takes a minute to check anyway so might as well
2022-10-11T21:09:48 < mawk> I read that in ASUD, a risk reduction journal in France 
2022-10-11T21:09:50 < mawk> yeah
2022-10-11T21:09:53 < bitmask> a part of the heart beat cycle
2022-10-11T21:10:01 < mawk> Steffanx- it's some component of your heart rythm
2022-10-11T21:10:08 < mawk> the time interval between the Q and the T time markers, I guess
2022-10-11T21:10:17 < mawk> and if it's too long you can die suddenly or something 
2022-10-11T21:10:50 < bitmask> supposedly methadone can elongate the rhythm which could be dangrous 
2022-10-11T21:10:56 < mawk> yeah
2022-10-11T21:10:56 < bitmask> oh ok
2022-10-11T21:11:20 < mawk> with long QT you can die of jumpscare or things like that
2022-10-11T21:11:22 < bitmask> just ask the clinic to test you
2022-10-11T21:11:22 < mawk> not very cool
2022-10-11T21:11:34 < mawk> yeah they did at the start of treatment 
2022-10-11T21:11:36 < Steffanx-> Oh skipped that biology class I guess
2022-10-11T21:11:37 < mawk> I can ask for a new one
2022-10-11T21:12:03 < bitmask> even if its not from methadone its a free heart test :)
2022-10-11T21:13:12 < mawk> methadone with crohn's sounds awful
2022-10-11T21:13:23 < mawk> I destroy toilets everywhere I go and I don't have crohn's
2022-10-11T21:13:28 < bitmask> heh
2022-10-11T21:13:30 < mawk> but I eat zero fiber
2022-10-11T21:13:45 < mawk> I hope at 37.5mg the constipation is less than at 450 at least
2022-10-11T21:13:57 < Steffanx-> Lol
2022-10-11T21:14:00 < mawk> I saw there is this opioid antagonist that doesn't cross the BBB that you can take
2022-10-11T21:14:01 < Steffanx-> Long way to go
2022-10-11T21:14:08 < mawk> and it reverses methadone effects on the GI tract
2022-10-11T21:14:13 < mawk> I think it's been FDA approved 
2022-10-11T21:14:19 < mawk> if you're in the us you can try that
2022-10-11T21:15:03 < Steffanx-> Also lol you mawk. You've been deadly quiet lately. And you come back to life when it's all about drugs and crap 😋

2022-10-11T21:15:30 < mawk> yeah bitmask 
2022-10-11T21:15:48 < bitmask> i shit once a week, sometimes every other week
2022-10-11T21:16:11 < Steffanx-> Gotta monitor the bridges mawk?
2022-10-11T21:16:21 < mawk> just to visit
2022-10-11T21:16:30 < mawk> yeah same bitmask 
2022-10-11T21:16:30 < bitmask> though my gut hasnt been well the past couple weeks so its slightly more often and different
2022-10-11T21:16:47 < mawk> on codeine it was worse though
2022-10-11T21:16:52 < mawk> methadone can be managable if I eat fiber
2022-10-11T21:16:57 < mawk> which I don't because McDonald's is tasty
2022-10-11T21:17:25 < mawk> since I took it from such a young age I thought it was normal to shit only every 2 weeks
2022-10-11T21:17:32 < mawk> then I realized people go everyday or something 
2022-10-11T21:17:33 < mawk> weird
2022-10-11T21:17:35 < bitmask> the crohn's is mostly right at the end of my small intestine so I think its hard for stuffs to enter my colon
2022-10-11T21:18:07 < mawk> I see
2022-10-11T21:18:19 < bitmask> i have a colonoscopy and MRI coming up in like a month
2022-10-11T21:19:03 < Steffanx-> Colonoscopy fun times
2022-10-11T21:19:11 < bitmask> its the prep that sucks
2022-10-11T21:19:16 < kaki> are they going to remove a part of small intestine?
2022-10-11T21:19:25 < bitmask> no, at least not yet
2022-10-11T21:19:48 < bitmask> depends what the colonoscopy shows i guess
2022-10-11T21:20:32 < Steffanx-> 1/week..
2022-10-11T21:20:35 < Steffanx->  How?
2022-10-11T21:20:45 < Steffanx-> Where does the food go?
2022-10-11T21:20:47 < bitmask> he couldnt get the camera into the bad area last time because it was too inflamed. i think he wants to be able to see it this time
2022-10-11T21:21:06 < bitmask> when it comes out its just really dense/hard
2022-10-11T21:21:10 < mawk> Steffanx- 1 every 2 weeks, even
2022-10-11T21:21:11 < Steffanx-> Lol.
2022-10-11T21:21:18 < bitmask> its like rocks
2022-10-11T21:21:21 < bitmask> :P
2022-10-11T21:21:36 < mawk> also I eat only once a day

2022-10-11T21:21:52 < mawk> why
2022-10-11T21:21:56 < Steffanx-> ##poop32

2022-10-11T21:22:18 < mawk> there's no price that would convince me to partake in that

2022-10-11T21:31:17 < rustyaxe> you're not gonna shit cubes like that one australian animal tho
2022-10-11T21:31:33 < rustyaxe> wombat.

2022-10-11T21:32:54 < Steffanx-> I thought finnish were ICECOLD
2022-10-11T21:33:08 < rustyaxe> Ya, if wombats even exist, they supposedly shit cube shaped poop. But i dont believe in australia as A: I've never met an australian, B: I've never seen australia or heard of it EXCEPT on teevee and internet and C: most importantly australia seems to be whats left of the british east indies trading company -- PIRATES!
2022-10-11T21:33:36 < Steffanx-> U wot moite??
2022-10-11T21:33:51 < rustyaxe> you have mites?
2022-10-11T21:34:35 < rustyaxe> i mean ive met people on the internet who claim they're from australia, yes. But that well could be just internet myths.

2022-10-11T21:37:02 < Steffanx-> i believed it

2022-10-11T21:41:41 < machinehum> I haven't built it yet, no thanks to you guys not reviewing my shit

2022-10-11T22:11:11 < qyx> FL5160?
2022-10-11T22:11:13 < qyx> rings a bell

2022-10-11T22:23:01 < kaki> lan partys we have been having couple times with friends are nice
2022-10-11T22:23:48 < Steffanx-> Are finnish lan parties like a sauna or more like a bus stop?
2022-10-11T22:25:15 < kaki> just start drinking bier
2022-10-11T22:26:10 < kaki> pizza delivered to door
2022-10-11T22:26:19 < Steffanx-> So its starts cold and distant, but turns into something warm and cosy.
2022-10-11T22:26:40 < kaki> grind some game as team for whole evening and night
2022-10-11T22:28:28 < bitmask> do people still play fortnite? i never tried it
2022-10-11T22:29:14 < Steffanx-> Me neither. Never sounded like a game for me.
2022-10-11T22:29:35 < bitmask> i used to play counterstrike when it first came out
2022-10-11T22:30:21 < bitmask> I was always terrible at it, im a fairly patient person but I would always just rush out and die :P
2022-10-11T22:34:46 < kaki> bitmask: it's for pre-teens
2022-10-11T22:34:53 < bitmask> how so
2022-10-11T22:37:16 < bitmask> did you see the ariana grande concert in it? I dont like her but I was curious so I watched it on youtube. it was kinda cool
2022-10-11T22:37:31 < kaki> internets says 60% 18-24 though
2022-10-11T22:37:33 < bitmask> though what I just said proves your point
2022-10-11T22:39:13 < bitmask> since when is 18-24 preteens :P
2022-10-11T22:42:23 < kaki> it isn't. kids just got super hyped about the dances, characters etc. but may not even have played the game themselfs
2022-10-11T22:43:22 < bitmask> i see
2022-10-11T22:44:12 < kaki> but I think 15-20 is that age range in any game where hours accumulate

2022-10-11T23:52:50 < kaki> anyways
2022-10-11T23:53:40 < kaki> does basic particle filters do anything or do I need those filters that have more ratings to filter nuclear dust?
--- Day changed ke loka 12 2022
2022-10-12T00:11:55 < Xogium> kaki: tbh I wouldn't worry about the dust but the radiation in the air ;)
2022-10-12T00:12:14 < kaki> main thing is to not get it in you
2022-10-12T00:12:22 < Xogium> I mean okay radioactive dust is bad but it emits radiation just as well on the ground, right ?
2022-10-12T00:12:30 < kaki> yes
2022-10-12T00:12:35 < kaki> and on your clothes

2022-10-12T00:12:59 < Xogium> woops
2022-10-12T00:13:39 < Xogium> kaki: do you have huh, how's that called again
2022-10-12T00:13:45 < Xogium> iodine pills ?
2022-10-12T00:14:25 < Xogium> I've heard a lot about how it can be helpful to take that
2022-10-12T00:15:10 < Xogium> then again maybe it is just helpful with nuclear reactor fuckups

2022-10-12T00:19:22 < Xogium> that's not very surprising
2022-10-12T00:19:32 < Xogium> when people panic over something, sure tends to do that

2022-10-12T00:19:57 < kaki> it happens time to time
2022-10-12T00:21:52 < Xogium> I remember at the start of the covid crisis, everyone rushed to buy toilet paper hehe
2022-10-12T00:22:24 < Xogium> some with good reasons, mind, but lot probably just stocked it up like mad
2022-10-12T00:23:52 < kaki> I think if there is enough panic buying eventually everyone is stocked

2022-10-12T00:54:34 < kaki> is exposed reactor core worse than nukes?
2022-10-12T00:54:39 < specing> people live fine in hiroshima and nagasaki
2022-10-12T00:54:47 < specing> kaki: yep, lots worse
2022-10-12T00:55:08 < kaki> because of there is thousands of kilograms of the stuff?
2022-10-12T00:55:55 < specing> nah, because nukes kill with shock waves, and to get better shock waves you have to use up the material efficiently
2022-10-12T00:56:26 < specing> whereas exposed reactor cores equal very slow reaction
2022-10-12T00:56:34 < specing> though I'm no physicist
2022-10-12T00:56:47 < kaki> yeah
2022-10-12T00:56:54 < karlp> I'd imagine that if it's exposed and it's not meant to me, it's probably no longer running in any form of "stable slow" reaction process...
2022-10-12T00:56:56 < kaki> it's blowing the material into skies
2022-10-12T00:57:14 < kaki> and there is thousands of kilograms of that stuff
2022-10-12T00:58:18 < specing> yeah, but when it blows material into skies it disperses rapidly and thus reaction slows down to a crawl
2022-10-12T01:00:00 < qyx> but nowadays reactors are not carbon moderated, there is nothing to burn and blow
2022-10-12T01:00:56 < specing> on the other hand, nukes might reverse climate change by (1) putting material into sky to block sunlight (2) killing our fossil-fieled economy
2022-10-12T01:01:53 < qyx> russia is doing their best to kill fossils atm
2022-10-12T01:02:34 < lagash> specing: technically that doesn't reverse climate change, it makes more of it, and much more quickly...
2022-10-12T01:03:15 < specing> lagash: how so?
2022-10-12T01:03:26 < lagash> Oh, and there's no disputing it's anthropogenic... :P

2022-10-12T18:42:49 < karlp> there's only 10 of them, and none anywhere int he west either.
2022-10-12T18:42:59 < karlp> re-designing, this is a sign I've been doing it wrong :)
2022-10-12T19:07:01 < catphish_> oh yeah, only 10 :(
2022-10-12T19:07:09 < catphish_> use different part :)
2022-10-12T19:07:59 < catphish_> that looks like an extremely generic mosfet, why does it matter?
2022-10-12T19:08:18 < catphish_> apart from the fact that it can carry 210A :D
2022-10-12T19:09:27 < kaki> https://www.diodes.com/assets/Datasheets/DMN67D7L.pdf
2022-10-12T19:10:19 < kaki> 210mA
2022-10-12T19:11:49 < kaki> this thing looks rather unremarkable
2022-10-12T19:11:54 < catphish_> i use C8545
2022-10-12T19:12:06 < catphish_> (which is a JLC basic part)
2022-10-12T19:12:23 < kaki> are you talking JLC code language?
2022-10-12T19:12:32 < catphish_> that a LCSC code
2022-10-12T19:12:51 < catphish_> MFG part number is 2N7002 but i assume that's generic
2022-10-12T19:13:37 < catphish_> this https://www.lcsc.com/product-detail/MOSFETs_Jiangsu-Changjing-Electronics-Technology-Co-Ltd-2N7002_C8545.html
2022-10-12T19:14:05 < kaki> thats even more generic
2022-10-12T19:14:26 < kaki> it's the very basic signal mosfet
2022-10-12T19:14:32 < catphish_> it's the most generic mosfet that exists, basically free from JLC
2022-10-12T19:15:02 < catphish_> so so was the one karlp posted, at 5 ohms, it's hardly a power device
2022-10-12T19:16:18 < kaki> ye
2022-10-12T19:16:48 < kaki> sufficient to switch power to some IC or region
2022-10-12T19:19:39 < karlp> it's special because it has a 40V limit on the gate/source
2022-10-12T19:19:48 < karlp> that's _very_ uncommon.
2022-10-12T19:26:34 < kaki> ah
2022-10-12T19:26:43 < kaki> why though?
2022-10-12T19:26:50 < kaki> you have that in your design?
2022-10-12T19:33:20 < kaki> if my design had gate voltages >15V I would think hard
2022-10-12T19:34:36 < jpa-> think of the electrons, they have a fear of high potential differences
2022-10-12T19:35:16 < karlp> here, you can play with it: https://tinyurl.com/2ehapq6c
2022-10-12T19:35:33 < karlp> it's allowing 5/10/12/24V wet driven voltages to make a digital input...
2022-10-12T19:36:50 < kaki> wet?
2022-10-12T19:38:14 < kaki> ah fet
2022-10-12T19:40:25 < jpa-> karlp: why not just stick a zener in it, or use a fet with built-in clamp?
2022-10-12T19:43:40 < karlp> a zener in the divider makes ~no real difference to the voltages seen, or the current consumed in the divider, for the voltages of interest, and is an extra part?
2022-10-12T19:44:08 < karlp> kaki wet as in actively driving inputs, as opposed to dry, where the input is just a contact opening and closing with no applied voltage.
2022-10-12T19:44:41 < kaki> ah
2022-10-12T19:44:48 < jpa-> yeah, i guess your divider is fine for 20V Vgs limit - what was this about 40V?
2022-10-12T19:45:59 < karlp> the old divider was 300ohm:1M,
2022-10-12T19:46:32 < karlp> and the 24v tvs diodes have a clamping voltage of like 39V
2022-10-12T19:46:49 < karlp> but yeh, going iwth 30V fet now, and better dividers.
2022-10-12T19:49:00 < BrainDamage> karlp: do you have bjts the design?
2022-10-12T19:49:48 < karlp> no, but I was thinking, "are we doign this wrong? shoudl we just use bjts or something?" 
2022-10-12T19:50:16 < BrainDamage> karlp: https://tinyurl.com/2epkf4xw
2022-10-12T19:50:47 < BrainDamage> the bjts _can_be replaced with mosfets, the regular Vgate kind
2022-10-12T19:51:21 < karlp> why the two transistors?
2022-10-12T19:51:37 < BrainDamage> because that's the configuration that allows you to swap with mosfets
2022-10-12T19:51:44 < karlp> that design currently uses more power, and two parts though? what's the advantage?
2022-10-12T19:51:47 < BrainDamage> with bjts you can get away with a single one
2022-10-12T19:52:22 < karlp> I mean, the fets are only for that secetion, doesn't matter to me if it's fet or bjt really.
2022-10-12T19:52:35 < BrainDamage> oh, then a single bjt will work
2022-10-12T19:56:34 < jpa-> i have often seen a dual-BJT constant current source + opto isolator being used for digital inputs that need to have a wide voltage range
2022-10-12T19:58:00 < kaki> why dual-bjt?
2022-10-12T19:58:55 < jpa-> https://jpa.kapsi.fi/stuff/pix/wide_voltage_range_digital_input.png  this kind of stuff
2022-10-12T19:59:01 < jpa-> a bit overkill for many cases probably
2022-10-12T19:59:13 < karlp> like this BrainDamage: seems to work well then I guess? https://tinyurl.com/2fhjxp9p
2022-10-12T19:59:49 < jpa-> karlp: do note that without a pull-down resistor, that BJT will turn off quite slowly if the input is disconnected
2022-10-12T19:59:58 < kaki> jpa-: I need to save that
2022-10-12T20:00:00 < jpa-> and even otherwise, BJTs can be a bit slow to get out of saturation
2022-10-12T20:00:49 < kaki> what if I want range of... 12-400V :o
2022-10-12T20:01:49 < karlp> slow like, "under 100khz" or slow like "100hz" ?

2022-10-12T20:07:37 < jpa-> karlp: i'd say 1-100µs delay depending on transistor
2022-10-12T20:08:04 < jpa-> also kind of poor noise immunity in the case where the input is disconnected, that is basically the circuit used for contactless AC voltage detectors
2022-10-12T20:09:13 < jpa-> with a bjt i usually put the pulldown resistor on the left side of the base resistor, but i'm not sure if that makes a difference
2022-10-12T20:10:11 < karlp> eh, I'm not seeing any advantage over the fet version right now, except having to find bjts that have ~30-40V ratings still, which is more common sure, but 
2022-10-12T20:10:37 < BrainDamage> karlp: yes
2022-10-12T20:11:32 < jpa-> the BJT input will stay at 0.7V max (except for negative voltages)
2022-10-12T20:13:40 < karlp> oh , right, yeah, was just looking at that.  all the drop is on the base resistor, 
2022-10-12T20:13:51 < karlp> but you get non-zero emitter current, if that matters

2022-10-12T20:22:19 < machinehum1> 1k
2022-10-12T20:22:31 < jpa-> datasheet fig 11 gives Vce_sat = 0.10V for 1mA at 20°C
2022-10-12T20:22:51 < jpa-> seems reasonable to get 0.03V at 0.01mA

2022-10-12T23:32:35 < begriffs> Subjective question, but how popular is libopencm3 vs something older like CMSIS?
2022-10-12T23:33:39 < qyx> subjective answer, I am using libopencm3 only so far
2022-10-12T23:35:06 < begriffs> Would you say it's better than CMSIS for low level control of the device, or is that just what you happened to learn and use first?
2022-10-12T23:36:02 < qyx> it is what I happened to learn and it matched my mindset
2022-10-12T23:36:14 < begriffs> It does seem like libopencm3 includes extra stuff for peripherals that I'd otherwise have to piece together from CMSIS-Driver or something.
2022-10-12T23:36:23 < qyx> I also tried stdperiph, noway
2022-10-12T23:36:39 < qyx> chibios hal was terrible
2022-10-12T23:36:59 < qyx> but that was 10y ago

2022-10-12T23:38:27 < qyx> I don't like the way it initialises things using structs
2022-10-12T23:39:02 < qyx> whats that retarded design pattern
2022-10-12T23:39:07 < begriffs> OK. As a beginner I'm trying to get a reasonable understanding of how the MCU works (so not using too much abstraction), while trying to invest time into a library that's been around and is stable.

2022-10-12T23:46:07 < begriffs> Anyone know how I'm supposed to use CMSIS outside of IDEs? Do I have to dig parts of of the following repos?: ARM-software/CMSIS_5 ARM-software/CMSIS-Driver STMicroelectronics/STM32CubeF4 STMicroelectronics/cmsis_device_f4
2022-10-12T23:46:54 < begriffs> Kind of build object files from all these repos and put them together to match my STM32F411 and the peripherals I want to use?
2022-10-12T23:49:26 < begriffs> Maybe that's the appeal of libopencm3, because I can link a single libopencm3_stm32f4.a and away I go.

2022-10-13T18:58:23 < karlp> you can "fixup" inline search results, but ... if you try and fix up a second one, it just applies that fixup to the first one.
2022-10-13T19:00:39 < karlp> like, it has a column for uploading the lcsc part #, but if you _just_ upload that, it jsut fails to find anything :|

2022-10-13T19:37:56 < karlp> lol, I fiddled it enought o make it's bom import happy, so you have 8 of this, 4 of this, blah, and you can say "this, times N quantity, add to cart"
2022-10-13T19:37:58 < karlp> so far so good,
2022-10-13T19:38:17 < karlp> but _before_ it does the "times N quantity" it raises _all_ of the individuals up to the "min ordered quantity"
2022-10-13T19:38:54 < karlp> so for a bom line item of count 2, times 50, with a minimum of 50, you end up having 50*50 in your cart, instead of 100...
2022-10-13T19:38:57 < karlp> top notch.
2022-10-13T20:08:11 < mawk> bitmask it's by doing what you do that I ended up horribly slipping
2022-10-13T20:08:18 < mawk> taking more some day and less the next
2022-10-13T20:08:33 < mawk> it ended up becoming taking more everyday and buy the rest myself very quickly 
2022-10-13T20:08:41 < Steffanx-> I expected Mr mawk to be smarter
2022-10-13T20:08:47 < mawk> why
2022-10-13T20:09:15 < Steffanx-> That ^
2022-10-13T20:09:25 < mawk> it's not me
2022-10-13T20:09:32 < mawk> it's the daemon lurking in my subconscious 
2022-10-13T20:09:49 < mawk> whose goal is maximizing the activation of the feel good receptors 
2022-10-13T20:10:02 < mawk> your rational mind can't compete
2022-10-13T20:10:49 < Steffanx-> Now you sound religious..
2022-10-13T20:12:38 < bitmask> i havent purchased any drugs since I started methadone, even when I take more on some days
2022-10-13T20:13:02 < bitmask> i just suffer a bit on days that i have less
2022-10-13T20:14:53 < bitmask> maybe i smoked weed once or twice around when I first started but that was years ago
2022-10-13T20:16:18 < mawk> it's not other drugs that I buy, it's just more methadone
2022-10-13T20:16:23 < mawk> to fill in the rest of the week
2022-10-13T20:17:14 < bitmask> i understand, im including methadone in that list
2022-10-13T20:17:35 < bitmask> ive never bought extra to make up for when i took extra on some day
2022-10-13T20:17:54 < bitmask> it would be nice to have but im not willing to go down that path
2022-10-13T20:18:12 < bitmask> because i know that will lead me to taking more and more
2022-10-13T20:20:01 < bitmask> it does suck that my stomach isn't doing well. I'm going to have 2 shitty days instead of my usual 1 before I pick up on tuesday
2022-10-13T20:22:07 < bitmask> ugh vulkan is pissing me off
2022-10-13T20:22:22 < Steffanx-> Time for a walk outside
2022-10-13T20:22:46 < bitmask> no i just did take a break, im about to start back up again
2022-10-13T20:23:18 < bitmask> i have something to try at least
2022-10-13T20:28:47 < mawk> good then bitmask 
2022-10-13T20:28:54 < mawk> you have more willpower than me
2022-10-13T20:29:06 < mawk> although I did what you did for 4 years without slipping up
2022-10-13T20:29:09 < mawk> but I eventually did
2022-10-13T20:29:20 < mawk> after my Ukrainian gf got deported by Mark Rutte I was quite sad 
2022-10-13T20:29:28 < mawk> so I gobbled up all my stash
2022-10-13T20:49:05 < Steffanx-> blame ivan, not rutte
2022-10-13T20:49:12 < Steffanx-> or boris or whatever the name was

2022-10-14T13:48:57 < specing> install linux?
2022-10-14T13:54:28 < Laurence_b> lol yeah
2022-10-14T14:05:29 < Laurence_b> how do I read return code from a command on windows cmd?
2022-10-14T14:10:10 < englishman> i install openvpn then load the config file then click the button then it works
2022-10-14T14:11:16 < karlp> benishor: what are you collecting it with? normally that end has the commands for configuring it... 
2022-10-14T14:11:38 < karlp> benishor: like, for oocd it's just a line like "tpiu config internal swo.dump.log uart off <coreclkspeed>" or something in your openocd.cfg
2022-10-14T14:14:51 < benishor> karlp: and what is the coreclkspeed exactly?
2022-10-14T14:15:37 < benishor> is it the HSE source or the final clock after the PLL?
2022-10-14T14:34:37 < karlp> final clock, hclk..
2022-10-14T14:38:06 < benishor> no init needed on the software side?
2022-10-14T14:38:12 < benishor> enabling swo?
2022-10-14T14:39:02 < karlp> I mean, you can, but IMO it's dumb and just wastes code space.
2022-10-14T14:39:08 < karlp> let the debugger do that itself.
2022-10-14T14:39:31 < karlp> TIL about current mode vs voltage mode phys for the first time.
2022-10-14T14:39:37 < karlp> now I understand the extra 2V shit sometimes.
2022-10-14T14:39:58 < karlp> I'm not sure I'm any closer to understanding the "right" connection between shield and ground for a magjack though

2022-10-14T14:42:34  * Laurence_b is getting hardfault on tms320f28388d
2022-10-14T14:43:01 < Laurence_b> looks like it might be caused by simulink ipc blocks - if I set ipc to blocking it doesnt happen
2022-10-14T14:43:19 < Laurence_b> but thats when I set blocking on the tms320 end not the cortex m4 end
2022-10-14T14:43:33 < Laurence_b> any clues whats going on?
2022-10-14T14:46:10 < karlp> benishor: yay, more trace users!

2022-10-15T16:42:24 < bitmask> oh nvm, that was just a stupid mistake
2022-10-15T16:44:09 < bitmask> ugh, one more test
2022-10-15T16:59:37 < catphish_> i might do some work in on it now actually, unfortunately vulkan requires a LOT of work to get everything in place, i'm still understanding all the memory management, cant write much in the way of shaders until that's all done
2022-10-15T17:00:09 < BrainDamage> opengl is more like a 3d engine builtin, vulkan you write the 3d engine
2022-10-15T17:01:30 < catphish_> well opengl handles all the low level management of resources for you
2022-10-15T17:02:19 < catphish_> with vulkan, if you want some data in VRAM, you have to manage the DMA transfers :)
2022-10-15T17:03:51 < catphish_> and i still don't fully understand its rendering pipeline yet
2022-10-15T17:06:52 < bitmask> There are a few things i have completely glossed over and use some default code I found. I'm not sure how things like pipeline barriers come into play. I know they are used to keep the order of operations correct because vulkan is designed to be parallel but i wouldnt even know where to begin using them for anything special. I also have a bunch of design questions I'm not really sure about but other than that it mostly makes sense
2022-10-15T17:07:45 < bitmask> I also havent gotten into subpasses yet
2022-10-15T17:08:23 < catphish_> bitmask: are you using vulkan then?
2022-10-15T17:08:27 < bitmask> yea
2022-10-15T17:08:52 < catphish_> my code is just an implementation of https://vulkan-tutorial.com/ in C
2022-10-15T17:09:13 < bitmask> yea thats where I started too, I think i ended up liking vkguide.dev or whatever it is better though
2022-10-15T17:09:42 < catphish_> i suspect it will pay to do both
2022-10-15T17:09:47 < bitmask> definitely
2022-10-15T17:09:59 < bitmask> i know after finishing vulkan-tutorial i was still confused as hell
2022-10-15T17:10:35 < catphish_> it's mostly the render pipeline i kinda glossed over and just copied the code because i was getting impatient to see something on my screen!
2022-10-15T17:10:50 < catphish_> but clearly that's important, so i'll have to do this a couple of times
2022-10-15T17:12:27 < bitmask> i'm currently working on descriptor set management
2022-10-15T17:12:55 < bitmask> still now 100% sure what direction im going for everything related.

2022-10-15T17:23:03 < catphish_> i like OOP, and for a long time i thought i should learn C++ for classes, but a few weeks ago i learned go for some contract work, and that really made me realise that you can do OOP perfectly fine in C
2022-10-15T17:25:14 < bitmask> uhhh wha?
2022-10-15T17:26:29 < catphish_> i no longer feel that there's a meaningful difference between a class, and a file containing a struct and a series of functions that accept a pointer to that struct as their first argument
2022-10-15T17:28:53 < bitmask> if you are trying to replicate a feature why not just use the language that has said feature, what about inheritance, polymorphism, templates, all the benefits of the standard library
2022-10-15T17:29:41 < bitmask> smart pointers, containers, algorithms
2022-10-15T17:29:47 < catphish_> it's true that as programs get larger i might feel i'd benefit from inheritance
2022-10-15T17:30:16 < catphish_> but so far, i haven't felt i needed anything that was missing from C's standard library
2022-10-15T17:30:18 < catphish_> that may well change
2022-10-15T17:31:04 < bitmask> I never really put the effort into learning modern c++ until a year or two ago. its like a whole new language
2022-10-15T17:31:17 < catphish_> if C++ was merely C with with classes, i think i'd gravitate to it, but whenever i look at it, it just seems like a wild mess, starting at the very beginning with cout << "helo"
2022-10-15T17:33:21 < bitmask> with destructors and smart pointers its almost like having garbage collection. makes worrying about memory leaks a thing of the past
2022-10-15T17:33:51 < bitmask> anyway, to each his own, gonna take a break before I get back to coding
2022-10-15T17:33:58 < catphish_> enjoy
2022-10-15T17:35:02 < zyp> catphish_, judging C++20 by C++03 or whatever isn't really fair

2022-10-16T01:38:11 < karlp> I wonder if this is just the RMT implementation or something.

2022-10-16T16:02:15 < ventYl> to me that's not entirely surprising
2022-10-16T16:05:14 < specing> catphish_: if it copied the code, it can also copy the comments
2022-10-16T16:05:17 < specing> d'oh
2022-10-16T16:06:07 < catphish_> fsvo of copied, yes
2022-10-16T16:06:49 < ventYl> catphish_: do you know of any resource on some in-depth stuff about EVs?
2022-10-16T16:07:10 < ventYl> I'd like to see some "not so consumer" details on how they are built together but interwebs are only full of fuck
2022-10-16T16:08:34 < catphish_> ventYl: it's all a bit sporadic, probably best to focus on a specific vehicle, the openinverter wiki has a fair amount of information about individual parts
2022-10-16T16:08:56 < catphish_> ventYl: or you could read DIY build threads like mine
2022-10-16T16:08:56 < ventYl> catphish_: I have focus on two-to-three models
2022-10-16T16:10:08 < catphish_> the truth is i couldn't say where i got my information, except basically by googling specific devices and reading up on them, most of what i know comes from openinverter forum / wiki i think
2022-10-16T16:10:14 < ventYl> if our legislation wasn't a complete fuckup, I'd probably custom build one myself, but here it is almost impossible to legalize such build
2022-10-16T16:10:32 < catphish_> in UK it's easy as long as you don't modify the chassis
2022-10-16T16:10:47 < catphish_> though i suspect the law will soon change to require a proper test, which is still quite reasonable
2022-10-16T16:10:49 < ventYl> here it is hard. punktum
2022-10-16T16:11:05 < ventYl> any change on car. like *any* is fineable up to some 2k eur I think
2022-10-16T16:11:18 < catphish_> well that sucks, we love car mods in uk
2022-10-16T16:11:54 < catphish_> surely you have a process to approve a car though? but i assume it's hard
2022-10-16T16:12:12 < ventYl> if you can work around this by "this is just a spare part" formula, then you hit the wall with the fact, that it is not possible to change vehicle's fuel, except of gasoline to gasoline + LPG/CNG or diesel to diesel + CNG
2022-10-16T16:13:10 < ventYl> catphish_: well, law recognizes that process, but AFAIK, there are rules for the process missing, or it is so hard, that even one small, low volume manufacturer transported their cars abroad, approved cars there and then re-imported them locally
2022-10-16T16:14:22 < catphish_> that's quite gay
2022-10-16T16:15:19 < ventYl> even some improvements made abroad, which are approved are nullified once car is imported
2022-10-16T16:15:49 < ventYl> like, mine was EURO 2 back in germany, but as I imported it, it became EURO 1, because it was made as such and changes made in germany are not recognized here
2022-10-16T16:16:38 < catphish_> in UK you can't change emissions certification
2022-10-16T16:17:45 < catphish_> my car was built as euro4 with 205 g/km of CO2 emissions, that can never change, not if it has a V12 installed, not if it has an electric motor installed
2022-10-16T16:18:23 < catphish_> i guess they couldn't be bothered to make a process to recertify
2022-10-16T16:21:02 < ventYl> in germany, you have approved devices with list of approved engines you can attach the devices to. you first have to pass regular emission control for current emission standard, then you have the device mounted by approved workshop and then you proceed to another emission test for new emission standard
2022-10-16T16:21:20 < ventYl> if you pass it, then the device becomes mandatory part of car and from that time on, the new emission standard becomes mandatory for you
2022-10-16T16:21:58 < catphish_> are you in germany?
2022-10-16T16:22:06 < ventYl> euro 1 to 2 is fairly trivial, because the most crucial change was that euro 2 has some means of treatment of cold-running emissions, while euro 1 does not have any
2022-10-16T16:22:28 < ventYl> nope, i am a bit more towards east
2022-10-16T16:22:55 < catphish_> ah ok, i was going to say, getting an EV conversion approved in germany requires some specific tests but 100% possible on a DIY budget
2022-10-16T16:24:00 < catphish_> i should visit the east one day
2022-10-16T16:24:17 < ventYl> for me it would probably easiest to simply approve the car in poland and then re-import it here
2022-10-16T16:25:32 < ventYl> or buy regular EV
2022-10-16T16:25:37 < ventYl> I am in no need of long range
2022-10-16T16:26:08 < catphish_> if you just want an EV, the best approach is to buy one
2022-10-16T16:26:15 < catphish_> leaf is getting cheap now
2022-10-16T16:27:21 < catphish_> you can buy mine if you like
2022-10-16T16:29:34 < ventYl> I'd prefer something with thermal-managed battery pack, which is not the case of first leafs, which are dead cheap
2022-10-16T16:29:43 < ventYl> this is probably the reason, batpacks are degraded
2022-10-16T16:29:57 < catphish_> mine has a battery temperature readout on the dash :D
2022-10-16T16:30:18 < ventYl> your's is also a RHD
2022-10-16T16:30:23 < catphish_> also true
2022-10-16T16:30:34 < catphish_> mine has no actual battery cooling or heating though
2022-10-16T16:30:43 < catphish_> it has a port for that, but i never connected anything to it
2022-10-16T16:30:43 < ventYl> which became like completely useless in continental europe after brexit
2022-10-16T16:31:04 < catphish_> they were useless before brexit
2022-10-16T16:31:09 < catphish_> you can't see where you're going
2022-10-16T16:31:23 < ventYl> but at least you could legally register one
2022-10-16T16:31:29 < catphish_> can you not any more?
2022-10-16T16:31:44 < catphish_> afaik it's fine to register LHD in UK, it's just stupid
2022-10-16T16:32:00 < ventYl> at least not here
2022-10-16T16:32:19 < ventYl> before that, you could register RHD here if you owned it in UK for at least six months prior relocation
2022-10-16T16:32:19 < catphish_> i'm getting a broken surface pro tomorrow, i overpaid for it, i do hope i can fix it :)
2022-10-16T16:32:49 < ventYl> *but* you couldn't sell it later
2022-10-16T16:33:41 < ventYl> the law was a clear statement of "we don't want RHD cars here, but EU forced us to accept them because of free citizens and goods movement. so this is the minimum what we had to do"
2022-10-16T16:34:13 < catphish_> sounds like your government just just love cars
2022-10-16T16:35:02 < ventYl> as long as you have unmodified LHD car you are mostly OK

2022-10-16T16:46:36 < ventYl> eh, ok EVs with no thermal management are not that rare
2022-10-16T16:59:26 < zyp> my e-golf doesn't have thermal management of the battery
2022-10-16T17:02:17 < ventYl> e-golf is the one I am interested in
2022-10-16T17:02:40 < zyp> which gen?
2022-10-16T17:02:49 < ventYl> whatever I can buy used :>
2022-10-16T17:02:53 < zyp> mine is first, MY16
2022-10-16T17:03:08 < ventYl> one I saw was probably first gen with 24.something kWh batpack
2022-10-16T17:03:15 < zyp> yeah
2022-10-16T17:03:20 < ventYl> with some 60k km on clock
2022-10-16T17:03:38 < zyp> mine is at 100k+
2022-10-16T17:04:02 < ventYl> at this pace, it would probably take me 20 years to make another 100k with any car
2022-10-16T17:04:02 < zyp> not sure exactly how much now, mostly my wife driving it nowadays
2022-10-16T17:04:43 < ventYl> I did 100k on my current car in some ~11 years, but I wasn't driving it exclusively
2022-10-16T17:05:00 < ventYl> but now I mostly work from home, so I do only like ~100km per week
2022-10-16T17:05:22 < zyp> my ioniq 5 recently passed 20k and I've had it for around a year now
2022-10-16T17:06:31 < zyp> my commute to work is only a few minutes, so that's not where the kilometers are going
2022-10-16T17:07:40 < zyp> IIRC home-kindergarden-work-home is almost exactly 10km on bicycle, probably not much longer by car
2022-10-16T17:08:30 < zyp> so that'll make up only like 10% of the driving I do
2022-10-16T17:08:44 < ventYl> where the rest goes then?
2022-10-16T17:10:38 < zyp> going other places, I guess
2022-10-16T17:11:06 < ventYl> that's what motorbike is for
2022-10-16T17:11:24 < ventYl> and with limited range of ~170km e-golf would probably also not be the main choice for such trips
2022-10-16T17:20:48 < specing>  <ventYl> eh, ok EVs with no thermal management are not that rare
2022-10-16T17:21:08 < specing> most EVs are in the personal mobility category: electric bicycles, scooters, etc
2022-10-16T17:21:34 < specing> no space to mount thermal management. And the price of it would be too high
2022-10-16T17:21:52 < ventYl> I meant EV cars :)
2022-10-16T17:22:11 < ventYl> I'd guess that if you have something so expensive, you will try at least a bit to perform some thermal management
2022-10-16T17:22:41 < ventYl> but with my expected mileage, except of sudden cell death, battery pack probably is not a huge deal for me
2022-10-16T17:23:00 < ventYl> I should worry more about general car rotting in electrics and structure
2022-10-16T17:23:20 < specing> ventYl: fyi it's easier to buy a used EV APC battery pack than it is to buy a used EV APC without a battery
2022-10-16T17:23:28 < specing> ebay has lots of offers
2022-10-16T17:23:42 < ventYl> ABC here stands for?
2022-10-16T17:23:44 < ventYl> *APC
2022-10-16T17:23:53 < specing> ventYl: armored personnel carrier (car)
2022-10-16T17:23:58 < ventYl> lol :D
2022-10-16T17:24:31 < ventYl> the EV I was interested in before even had batpack "user servicable"
2022-10-16T17:24:42 < ventYl> so you only had to replace parts of it
2022-10-16T17:24:52 < specing> cool, which one and what kind of battery
2022-10-16T17:25:01 < ventYl> the old Fiat 500e
2022-10-16T17:25:09 < specing> yeah, I don't think that's feasible outside of sudden cell death
2022-10-16T17:25:26 < specing> ventYl: how old, lead-acid?
2022-10-16T17:25:44 < ventYl> batpack is bolted together, internal wiring is also bolted together and there are only two types of modules used
2022-10-16T17:25:56 < ventYl> specing: no, it is li-ion, samsung SDI cells
2022-10-16T17:26:06 < ventYl> IIRC they are the same as used in some BMW i3s
2022-10-16T17:26:47 < ventYl> battery has thermal management, inverter is water cooled, motor is water cooled, pretty good construction given the Fiat CEOs statement that people shouldn't buy these cars

2022-10-16T17:45:22 < ventYl> zyp: the only reason, why I am not a fan of Fiat is that it completely lacks any means of fast charging and even the slow charging is like extremely slow
2022-10-16T17:47:50 < zyp> ah, yeah, fuck that
2022-10-16T17:48:30 < zyp> my egolf has a 3.7kW charger, which is reasonable enough for a battery that size
2022-10-16T17:48:41 < zyp> but I wouldn't have bought it if it didn't also have fast charging
2022-10-16T17:49:47 < ventYl> exactly
2022-10-16T17:50:30 < ventYl> I would probably even slowed down charging somehow as with my weekly mileage even as low as 1kW would be more than enough
2022-10-16T17:50:46 < zyp> fast charging isn't something you want to rely on for regular day to day use, but it's essential for the occasional longer trip
2022-10-16T17:51:17 < zyp> less so as the pack size increases though
2022-10-16T17:51:47 < zyp> I rarely fast charge the ioniq 5
2022-10-16T17:52:09 < zyp> except the onboard charger failed a few weeks ago…
2022-10-16T17:54:32 < zyp> dealer let me borrow a hyundai kona while waiting for a replacement, but shit is too small
2022-10-16T17:54:47 < ventYl> I hope I can rely on PV charging the car
2022-10-16T17:54:59 < ventYl> as I won't have any other sensible use for surplus electricity
2022-10-16T17:55:14 < zyp> offgrid?
2022-10-16T17:57:04 < ventYl> nope

2022-10-16T23:59:07 < Laurence_b> hmm I'm confused
2022-10-16T23:59:21 < Laurence_b> some hardware getting host not found socket errors connecting to server
2022-10-16T23:59:31 < Laurence_b> but other hardware works fine
2022-10-16T23:59:41 < Laurence_b> all hardware thinks server is on the same ip address
2022-10-16T23:59:57 < Laurence_b> some sort of routing error on the network?
--- Day changed ma loka 17 2022
2022-10-17T00:03:24 < qyx> I would say host not found means host not found
2022-10-17T00:03:49 < qyx> so either 1. your requested hostname is garbage or 2. your host is not found
2022-10-17T00:04:08 < catphish> what actual error is this "host not found"?
2022-10-17T00:04:09 < qyx> you are not dealing with IPs yet
2022-10-17T00:05:09 < qyx> and also what is "the hardware", because it may negative cache dns errors
2022-10-17T00:05:15 < catphish> it certainly sounds like a name lookup error, but it would be better if you could be more specific

2022-10-18T18:54:09 < Laurence_b> hi, anyone here used rsyslog.conf on lunix?
2022-10-18T18:57:05 < Laurence_b> my config has stopped working on more recent lunix for some reason
2022-10-18T18:57:33 < Laurence_b> I've put                     :msg, contains, "pam_unix" ~
2022-10-18T18:57:54 < Laurence_b> at top of file but its not having any effect, dunno if anyone has ever played with this on lunix?
2022-10-18T19:05:08 < PaulFertser> Laurence_b: did you check rsyslog log?
2022-10-18T19:05:15 < PaulFertser> Laurence_b: does it not warn you about deprecated actions?
2022-10-18T19:05:22 < Laurence_b> hmm
2022-10-18T19:05:29 < Laurence_b> where is that log located?
2022-10-18T19:06:21 < PaulFertser> Laurence_b: probably it prints it to stdout. You can usually see that with "systemctl status rsyslog.service" if you're using systemd.
2022-10-18T19:06:31 < PaulFertser> Here's what works for me on current Debian: :msg, contains, "udhcpc: sending renew to"      stop
2022-10-18T19:07:09 < Laurence_b> argggg
2022-10-18T19:07:23 < Laurence_b> retard assistant has just unplugged the power cable

2022-10-18T19:51:38 < PaulFertser> rsyslog deprecated it long time ago
2022-10-18T19:51:49 < Laurence_b> ah ok, this is making sense now

2022-10-18T19:52:40 < Laurence_b> hmm ok, yeah I want to ignore the matching messages
2022-10-18T19:54:30 < PaulFertser> I use "stop" statement.
2022-10-18T19:55:19 < Laurence_b> ah ok, thanks
2022-10-18T19:55:37 < Laurence_b> now I just have to wait for someone to plug the hardware back in....

2022-10-18T23:57:31 < kaki> in 80s when there was like 12 different DOS
2022-10-18T23:57:49 < kaki> was there any software compatibility across them?
--- Day changed ke loka 19 2022
2022-10-19T00:07:59 < PaulFertser> kaki: pc-dos, dr-dos were pretty compatible with ms-dos syscalls, yes.
2022-10-19T00:13:18 < PaulFertser> kaki: most advanced software were working with hardware directly, so other than using the file system, what DOS features do you have in mind?
2022-10-19T00:13:30 < kaki> idk
2022-10-19T00:13:41 < PaulFertser> Didn't you use DOS back in the 90s?
2022-10-19T00:13:53 < kaki> that was all dos was for? file system?
2022-10-19T00:14:31 < kaki> I used it yes but
2022-10-19T00:14:57 < Steffanx-> Just to play games..
2022-10-19T00:15:03 < kaki> yes
2022-10-19T00:15:46 < kaki> gayms used hardware directly
2022-10-19T00:17:50 < Steffanx-> I wasted so much time on Stunts
2022-10-19T00:17:56 < Steffanx-> Designing tracks
2022-10-19T00:23:00 < kaki> did dos have any multitasking?
2022-10-19T00:23:47 < PaulFertser> I think for certain purposes many apps were using BIOS APIs, and also there were separate VESA (graphics) APIs provided by a video card.
2022-10-19T00:25:11 < PaulFertser> kaki: no, but some people used https://en.wikipedia.org/wiki/DESQview . Windows up to 3.11 were running kinda on top of DOS and provided cooperative multitasking.

2022-10-19T00:58:33 < karlp> 6.0.8 is out, restored step export for me,
2022-10-19T00:58:48 < qyx> yeah better than nothing I would say
2022-10-19T01:00:50 < karlp> spent the day lokoing at 2.54mm sockets
2022-10-19T01:01:14 < karlp> they are _wildly_ expensive int he west nowadays.
2022-10-19T01:02:23 < karlp> but, I split a multi connnector symbol/footprint for a SoM into three symbols and three footprints that are all still lined up, so now correct BOM and pick and place files are generated for assembly.
2022-10-19T01:02:26 < karlp> so that's  win...
2022-10-19T01:02:47 < karlp> lol, playing with this esp shit some more...
2022-10-19T01:03:01 < karlp> have a basic proto of what I want, but now wanted to add all the goodies.
2022-10-19T01:03:24 < karlp> thought i'd experiment with one of the frameworks out there, as I want a nice OTA solution and some apis.
2022-10-19T01:03:45 < karlp> esphome looks like a nice basic package, lots built in, web ui, admin, remotes, lots of developers, lots of thought...
2022-10-19T01:04:07 < karlp> fastled and neopixelbus are both only supported when the underlying framework is "arduino"
2022-10-19T01:04:19 < karlp> but esp32c3 is onyl supported when the underlying framework is "esp-idf"
2022-10-19T01:14:08 < karlp> I also think it just downloaded a second fuckign copy of the toolchain 
2022-10-19T01:16:42 < karlp> god this is like docker gone wild.
2022-10-19T01:16:58 < karlp> platformio gone wild I guess.
2022-10-19T01:21:20 < qyx> nah I didn't even try to do ws281x on esp32c3
2022-10-19T01:23:43 < karlp> should have just ignored the C3....
2022-10-19T01:23:57 < karlp> nothing but more toolchain bloat and nothing extra :)

2022-10-19T11:46:22 < rustyaxe> Ok so ive come up with a stupid project.. I have ad9959 DDS with 4 outputs with an stm32f103 onboard that controls it, I need to send sound samples for I/Q to the L/R outputs of a pcm5102A (32bit 384khz PCM DAC) (i2c/i2s) and fetch L/R inputs from some yet unchosen but similarly spec dual ADC hooked to an stm32f401 dev board. WHat's the best route to go about presenting that as a sound card to a computer?
2022-10-19T11:47:06 < rustyaxe> maybe if theres enough grunt left, pass serial stream of commands through from that board to the ad9959 module, to avoid need for a usb hub
2022-10-19T12:03:01 < jpa-> pick the software platform you hate the least, rip off their USB audio example and be done?
2022-10-19T12:03:58 < qyx> sounds hard
2022-10-19T12:04:08 < rustyaxe> there is a linux driver for the DAC
2022-10-19T12:04:09 < rustyaxe> over i2c
2022-10-19T12:04:27 < rustyaxe> hifiberry uses it, fwiw. But that still leaves how to stuff it over USB

2022-10-19T14:27:47 < catphish_> ugh, i get myself in such a mess with header files in a multi-file C project
2022-10-19T14:33:18 < catphish_> i think i've got it right, i write the c file with all its headers at the top, then i *move* any definitions i want to export (and anything those exports depend on) to a h file, which is then included by its own C file as well as others that want to use my exports
2022-10-19T14:33:23 < jpa-> add more macros and the header file mess will not feel as big
2022-10-19T14:33:49 < catphish_> it's not about the size so much as what to put in there vs what to put in the C file
2022-10-19T14:34:58 < PaulFertser> catphish_: I suggest to always make all functions and global variables "static" by default.
2022-10-19T14:35:15 -!- CatCow [~wtf_over@98.246.223.133] has quit [Quit: My MacBook Air has gone to sleep. ZZZzzz…]
2022-10-19T14:35:36 < PaulFertser> Then when you see you want to use this function in another C file you remove static and add it to the corresponding header.
2022-10-19T14:35:44 < PaulFertser> (with extern for variables of course)
2022-10-19T14:36:27 < PaulFertser> And yes, the C file that implements the function should be also including its own header file for consistency.
2022-10-19T14:39:03 < catphish_> this is what i'm doing right now: https://github.com/catphish/vulkan_experimental/tree/master/engine - engine.c for example uses glfw3.h but its exported struct "engine" also requires that library for its definition, so i move the include to the h file, does that make sense?
2022-10-19T14:40:04 < PaulFertser> Yes
2022-10-19T14:40:37 < catphish_> great
2022-10-19T14:40:40 < catphish_> i'll carry on then
2022-10-19T14:42:01 < jpa-> catphish_: if other modules are not supposed to access the members of engine directly, you can also just forward-declare it ("struct engine;")
2022-10-19T14:42:16 < jpa-> it depends on if you want them to be able to do so or not

2022-10-19T16:13:04 < karlp> still, 0.50 currency units in china....
2022-10-19T16:13:13 < karlp> you should be using: https://advdownload.advantech.com/productfile/PIS/iDAQ-934/Product%20-%20Photo(B)/iDAQ934_01--_Square_S20211019152507.jpg

2022-10-19T16:15:58 < zyp> 36 vs 15 signals though
2022-10-19T16:16:48 < karlp> shush... I'm not seriously saying they should use dsub...
2022-10-19T16:17:06 < karlp> it was more a lol at the advantech design.

2022-10-19T16:42:39 < qyx> NI is also using DSUB15
2022-10-19T16:43:05 < qyx> the same power connector too

2022-10-19T16:47:19 < qyx> hah, I thing I may increase the cost with a factor of 4 at least
2022-10-19T16:47:21 < qyx> *think
2022-10-19T16:54:22 < karlp> qyx: nice :)
2022-10-19T16:54:52 < karlp> I suspect the real problem in this field is just getting your brand respected enough you can charge those
2022-10-19T16:55:01 < karlp> and part of that requires that massive fucking depth
2022-10-19T16:58:40 < qyx> or just narrow the business a bit
2022-10-19T16:58:52 < qyx> but yeah, automated eol testing requires that
2022-10-19T16:59:27 < qyx> but NI is absolutely not suited for long term monitoring because of their mechanical design, power draw, windows labview shit, etc.
2022-10-19T17:00:19 < jpa-> as a buyer in this field, the real problem is finding stuff with reasonable software & drivers
2022-10-19T17:00:29 < qyx> advantech is pretty popular here, NI is considered too expensive
2022-10-19T17:01:12 < qyx> but what is reasonable
2022-10-19T17:01:35 < jpa-> works and not riddled with ridiculous licenses and restrictions
2022-10-19T17:01:36 < qyx> being reasonable for me is not the same as being reasonable for automotive industrial park making car seats
2022-10-19T17:02:24 < qyx> where cost of getting labview runtime is not prohibitive and they are sure anyone can program it
2022-10-19T17:02:27 < qyx> lol at the last part

2022-10-19T17:30:36 < karlp> it blows my mind that the labview graphical thing with zero version control and "scripts" inside visual pieces is remotly considered a viable solution for any of this.
2022-10-19T17:30:58 < karlp> but it's like excel, someone gets it running, and it's "test people's world" so it jsut stays like that.
2022-10-19T17:31:04 < karlp> and test budgets just baloon 
2022-10-19T17:40:35 < zyp> same
2022-10-19T17:40:53 < qyx> everything labview related we uswd could have been made using few line python scrips

2022-10-19T21:51:47 < drzacek> hello there, I'm back with more noob questions
2022-10-19T21:53:27 < drzacek> so if I understand it right, I can either go for external crystal and configure HSE in cubemx, or skip the crystal and go for hsi - it will both work the same, but the frequency might not be exactly what I need, and it might be noticeable when I want to run some high speed communication, dunno, 100mhz spi on 64mhz mcu
2022-10-19T21:53:57 < drzacek> but for the most part it should be alright to just run on hsi and the mcu will still run "stable"?
2022-10-19T21:54:50 < drzacek> I ask cause apparently the tssop20 packages are lacking the rcc in/out pins
2022-10-19T21:57:08  * drzacek wants to drive few addressable LEDs with stm32g0
2022-10-19T22:00:29 < Steffanx-> Should be all fine for that purpose. If you really want to know look at the characteristics chapter and look for the max error etc. For those cheap ass addressable leds i cannot imagine its an issue. (as long as you're not too close to the limits etc.)
2022-10-19T22:01:10 < qyx> for SPI, freq doesn't matter as it is synchronous interface
2022-10-19T22:01:43 < qyx> for addressable LEDs, the tolerance is so wide that id doesn't matter either
2022-10-19T22:01:51 < drzacek> thx
2022-10-19T22:02:21 < Steffanx-> also good luck with 100 MHz spi @ 64 MHz mcu :P
2022-10-19T22:02:22 < drzacek> my only experiences with those leds is hooking some strips to preflashed esp32 modules
2022-10-19T22:02:46 < srk> ws2812?
2022-10-19T22:02:48 < drzacek> 'twas the joke
2022-10-19T22:02:51 < drzacek> ws2813
2022-10-19T22:03:07 < Steffanx-> no jokes in this channel please.
2022-10-19T22:03:52 < Steffanx-> working with stm32 is a serious and delicate business.
2022-10-19T22:07:30 < Steffanx-> for SPI it does matter when you (ab)use with those leds... 
2022-10-19T22:08:29 < drzacek> spi?
2022-10-19T22:09:25 < qyx> yes those LEDs are best driven with SPI
2022-10-19T22:09:27 < drzacek> I don't quit understand how those leds work, it looks super wonky to me - having 0 and 1 as pwm with different duty cycle?
2022-10-19T22:11:04 < qyx> if you are adventurous enough you can extract the WS281x code from my spaghetti https://gitlab.com/iqyx/vy-pi-nac/-/blob/master/fw/main.c
2022-10-19T22:11:46 < qyx> it starts at line 229, libopencm3 based
2022-10-19T22:12:32 < srk> seems like 2.5MHz 
2022-10-19T22:12:45 < qyx> this is super pro https://gitlab.com/iqyx/vy-pi-nac/-/blob/master/fw/main.c#L272
2022-10-19T22:14:13 < srk> haha
2022-10-19T22:14:36 < srk> https://www.pjrc.com/teensy/td_libs_OctoWS2811.html#tech
2022-10-19T22:15:38 < aandrew> qyx: that's not THAT bad, and depending on the compiler optimization, it'd probably end up unrolling things like that anyway
2022-10-19T22:15:58 < srk> you can also drive these using i2s
2022-10-19T22:16:03 < aandrew> laziness is a key indicator for pro... you are lazy where you can get away with it so you can expend your energy where it matters most
2022-10-19T22:16:23 < aandrew> srk: that would be more pro if speed/cpu time mattered
2022-10-19T22:17:08 < drzacek> too lazy for a loop - I love it
2022-10-19T22:18:42 < srk> aandrew: well someone's talking 100MHz on 64MHz mcu :)
2022-10-19T22:19:31 < qyx> it was a POC code, so apart from my OCPD and habits trying to keep the code quality at a reasonable level, it is total shit
2022-10-19T22:19:39 < qyx> but yeah, it probably unrolls
2022-10-19T22:20:12 < srk> -funroll-infinite-loops
2022-10-19T22:22:27 < drzacek> okay, I think I understand. so you configure spi to known freq, and then use the 8 bits in a byte as duty cycle. clever
2022-10-19T22:22:29 < srk> pros unroll by hand anyway cause -Os 
2022-10-19T22:22:39 < drzacek> and I think simpler than pwm with dma
2022-10-19T22:22:53 < qyx> yes
2022-10-19T22:22:58 < qyx> you can probably do the same with UART
2022-10-19T22:23:05 < qyx> although it is not that suitable for 4 MHz
2022-10-19T22:23:52 < drzacek> and hsi is ok for that?
2022-10-19T22:24:12 < qyx> the tolerance for those led strips is iirc ~400-800 kHz or so
2022-10-19T22:24:23  * drzacek assumes that's a lot
2022-10-19T22:24:24 < qyx> HSI is maybe 1% or so
2022-10-19T22:25:03 < qyx> but check yourself, I don't remember exactyl
2022-10-19T22:25:16  * drzacek checks himself

2022-10-20T11:48:38 < drzacek> hello there
2022-10-20T11:48:52 < drzacek> so exactly how bad is it to send something via uart from within the interrupt?
2022-10-20T11:53:51 < karlp> Steffanx-: switching to neopixelbus as some suggested makes.... zero difference.
2022-10-20T11:53:57  * karlp shrugs.
2022-10-20T11:54:06 < drzacek> I a have a situation when I need to send stuff at precise timing and set some GPIOs before/after uart transmit. I wrote it all inside interrupt - timer triggers it, and I read data from sensors, get some pins high, transmit via uart, then wait for gpio from the receiver to go high
2022-10-20T11:54:07 < karlp> kinda wild how widespread these thigns are with issues like that still so common.
2022-10-20T11:54:35 < karlp> drzacek: only you know your application requirements.
2022-10-20T11:55:12 < karlp> are you using out of band signalling via gpios? sounds wild and overwrought :)
2022-10-20T11:55:17 < drzacek> yeah, but somehow it doesn't feel right
2022-10-20T11:55:31 < karlp> well, we don't really know what you're really tryign to do (yet?)
2022-10-20T11:55:34 < drzacek> out of band?
2022-10-20T11:57:56 < drzacek> I am trying to send sensor data every 5ms, and I want this to be sent at precisely 5ms. not 2,3 or 4.32ms. and it is constructed this way, that I need to signal the receiver with GPIO that data will come - this way it all goes faster cause it triggers an interrupt at the receiver, and it gives feedback that it has received data via gpio too so I am sure that it all worked properly
2022-10-20T11:58:20 < drzacek> spoiler alert - it all seems to be working properly, been using this system for some time now. 
2022-10-20T11:59:06 < drzacek> but 1) I want to add the UART Receive to my stm32 project, need to read data between the transmits, and also would like to clean the code a bit, so it's less spaghetti and more meatballs

2022-10-20T12:52:59 < karlp> so, you'r eusing a gpio, to trigger an interrtupt on the remote system, so it it can read the uart?
2022-10-20T12:54:11 < karlp> just ignore the "hello, uart data coming now!" pin, and use the standard uart rx interrupts?
2022-10-20T12:54:34 < karlp> which side is the stm32, the sender or the receiver?
2022-10-20T12:55:07 < karlp> are you trying to _sense_ at a known interval, or _send_ at a known interval?
2022-10-20T12:55:32 < karlp> I'm guessing you are really trying to sense at a known sample rate, rather than do uart writes at a known rate, though they might be conflated right now.
2022-10-20T12:55:47 < qyx> all is manageable and quite common, you are overinnovating as a result of misunderstanding
2022-10-20T13:00:02 < karlp> that's ok, I emailed a vendor yesterday to ask if they had a version of their product I couldn't find...
2022-10-20T13:00:12 < karlp> it was... on the second page of the datasheet that I didn't scroll too
2022-10-20T13:14:39 < drzacek> karlp, I dont have access to the receiver end, it's just what it accepts
2022-10-20T13:14:57 < drzacek> stm32 is the sender, the master of the system
2022-10-20T13:15:42 < drzacek> karlp, kinda both, but I know what you mean. I want to acquire data at exact 5ms, and then quickly send it over, so it needs to happen fast, not after 3 miliseconds
2022-10-20T13:16:04 < drzacek> qyx, I'm open to all constructive criticism
2022-10-20T13:18:14 < qyx> idk if the receiver is behaving that way and you cannot change it, meh
2022-10-20T13:18:25 < karlp> pretty lol receiver though.
2022-10-20T13:18:32 < karlp> are you sure it's not just hardware flow control though?
2022-10-20T13:21:47 < drzacek> no
2022-10-20T13:22:15 < drzacek> it has also a signal to trigger transmit - it's a second microcontroller that handles rf communication
2022-10-20T13:22:38 < drzacek> I send data to, it buffers it, and I can tell it when to send, to have more fine-control over when the transmit really takes place
2022-10-20T13:23:20 < drzacek> but the gpio signaling is not a problem, that cost no time. I just wonder if doing uart transmit from interrupt is okay
2022-10-20T13:23:56 < drzacek> also I learned that any HAL function is kinda no-no in interrupt, since it has timeouts that are based on hal_delay, and hal_delay timer is not updated inside interrupt, so it can lock

2022-10-20T16:06:34 < drzacek> I want to drive few LEDs directly from the pin. I assume around 5mA per LED, in datasheet says something something 15 or 20mA per pin, 80mA total. I guess at 5 LEDs x 5mA I am safe?
2022-10-20T16:07:08 < drzacek> also, does it make a difference if I would drive the LEDs HIGH (1 is on), or low (the pin is ground)?

2022-10-21T13:10:25 < karlp> ok, yeah, the doors in the houses in the country were probably small, yes, but those are old houses,
2022-10-21T13:10:40 < karlp> the big fat cop guy is also a big guy, so he's goign to make everything look small anyway?
2022-10-21T13:12:17 < karlp> our internal doors are taller than our external door too? maybe some old weather idea?
2022-10-21T13:12:29 < karlp> how high are they in .sk?

2022-10-21T13:51:44 < kilobyte_ch> I'm trying to debug a Default_Handler/Infinite_Loop issue. For that I would like to get the values of the NVIC_IABRx Registers. Is there a way to get these values over GDB?
2022-10-21T13:52:09 < kilobyte_ch> I think STM32CubeIDE can display them somehow. But I'm using VSCode with GDB.
2022-10-21T13:54:36 < PaulFertser> kilobyte_ch: sure thing, if you compile and link with -ggdb3 you can use macro names in regular gdb print command.
2022-10-21T13:54:55 < PaulFertser> kilobyte_ch: so you can access them the same way you would access from firmware.
2022-10-21T13:56:17 < PaulFertser> kilobyte_ch: what target core is that, M0(+) or something better?
2022-10-21T14:02:12 < kilobyte_ch> PaulFertser: STM32F103VCT6 / M3
2022-10-21T14:02:33 < kilobyte_ch> PaulFertser: I have -ggdb3 set. So I should be able to print it with `print NVIC_IABR1`
2022-10-21T14:02:47 < kilobyte_ch> PaulFertser: GDB blames that it is not in the context
2022-10-21T14:08:16 < PaulFertser> kilobyte_ch: probably NVIC->IABR1 ?
2022-10-21T14:09:04 < PaulFertser> kilobyte_ch: on M3 you can use https://github.com/karlp/zypsnips/blob/master/armv7m-vecstate-zippe.gdb

2022-10-21T14:19:31 < karlp> do you have the correct ram size set?
2022-10-21T14:19:36 < karlp> when does this trigger?
2022-10-21T14:21:14 < kilobyte_ch> RAM size should be lonely set in the Linker file right? I have the Linker file from STM32CubeMX.
2022-10-21T14:21:36 < karlp> then you've probably stepped outside an array and trampled your stack somewhere.
2022-10-21T14:21:42 < PaulFertser> kilobyte_ch: "undefined instruction" in __aeabi_d2iz
2022-10-21T14:21:56 < PaulFertser> kilobyte_ch: run "disass" now
2022-10-21T14:22:19 < kilobyte_ch> The 3dcube.c:51 is a float operation.
2022-10-21T14:22:29 < kilobyte_ch> The same file works fine in Keil Compiler.
2022-10-21T14:22:42 < kilobyte_ch> So a wrong RAM setting or something like that sounds very likely.

2022-10-21T14:23:05 < PaulFertser> kilobyte_ch: yes, looks like you compile with gcc set to use FP core which STM32F103 doesn't have.
2022-10-21T14:23:22 < karlp> isn't the __aeabi stuff the sw stubs?

2022-10-21T14:27:20 < PaulFertser> kilobyte_ch: btw, if your intention is to work with "float" then you need to be quite careful as C standard automatically propogates that to "double" in many places.

2022-10-21T14:37:08 < karlp> if other float stuff is working, it's pretty unlikely to be a problem with floating point linking.
2022-10-21T14:37:30 < karlp> I'd guess you've trampled memory elsewhere, this just runs into it.
2022-10-21T14:38:10 < PaulFertser> But then reading from that memory would show that incorrect instruction.

2022-10-21T14:50:42 < kilobyte_ch> hmm, I think I start to know what the cause might be
2022-10-21T14:51:02 < kilobyte_ch> I'm not having the CFLAGS used for the Linker
2022-10-21T14:51:36 < karlp> you should.
2022-10-21T14:51:44 < karlp> and yes, that will do it.
2022-10-21T14:51:53 < PaulFertser> kilobyte_ch: -mthumb -march=armv7-m -mfloat-abi=soft
2022-10-21T14:52:31 < kilobyte_ch> Nice, now it works
2022-10-21T14:52:42 < karlp> (or -mcpu=cortex-m3 and drop the arch/thumb)
2022-10-21T14:53:12 < karlp> still confused why other float ops "worked" though.
2022-10-21T14:53:15 < kilobyte_ch> I had `-c` in the CFLAGS which prevented building succesfully when putting CFLAGS in the linking. Without -c I can now use CFLAGS for building and Linking.
2022-10-21T14:53:42 < kilobyte_ch> With other float ops I meant float ops in the main file. Not sure if they were treated differently
2022-10-21T14:54:16 < kilobyte_ch> And I just used the calculated float value in printf. Not sure if that made another difference.
2022-10-21T14:54:25 < karlp> you can split up however you like, in libopencm3 for instance the cpu/float is kept in ARCH_FLAGS
2022-10-21T14:54:36 < karlp> and then CFLAGS and LD_FLAGS both get ARCH_FLAGS added to it.
2022-10-21T14:54:47 < karlp> if you don't like calling your linker with "C" flags.
2022-10-21T14:54:54 < kilobyte_ch> But very interesting fault. I searched at the complete wrong spot. Thank you very much for the help!
2022-10-21T14:55:23 < kilobyte_ch> Well, I don't know why I put `-c` into the cflags. Removed it now and can use the same variable for both.

2022-10-21T17:00:25 < jbo> kilobyte_ch, oh, was your internet connection also upgraded from 1Gbps/1Gbps to 10Gbps/10Gbps for free recently?
2022-10-21T17:02:01 < kilobyte_ch> jbo: nope, still have P2P 1G. But soon P2P 25G. Could have P2MP 10G but I don't want touch this P2MP stuff with a stick..
2022-10-21T17:02:22 < Steffanx-> Talking about statistics. You are supposed to live in the most sunny part of swisserland 😝
2022-10-21T17:02:26 < Steffanx-> @ jbo
2022-10-21T17:02:33 < jbo> kilobyte_ch, yeah, a bit of the same problem here. I stuck to the 1G for now.
2022-10-21T17:02:45 < jbo> Steffanx-, yes
2022-10-21T17:02:58 < Steffanx-> I dont trust Swiss statistics anymore 
2022-10-21T17:02:59 < jbo> Steffanx-, today the weather is more or less what it was when you visited tho :D
2022-10-21T17:03:40 < kilobyte_ch> Weather here is pretty normal, just a bit rain in the morning. But a colleague told that it is pretty stormy where he is (swiss too).
2022-10-21T17:04:18 < jbo> wow, soon we can have ##stm32_ch
2022-10-21T17:05:33 < jpa-> yeah, in 2027 when we can get stm32's again
2022-10-21T17:06:22 < jbo> yeah, how is that looking these days? I don't have a lot of hardware projects at the moment :(
2022-10-21T17:07:06 < kilobyte_ch> The situation is basically that bad that we created some conversion boards to adapt other Microcontrollers onto STM32 footprints.
2022-10-21T17:07:53 < jbo> oh boy
2022-10-21T17:08:53 < jbo> and in our case we initially moved from developing hardware ourselves to supporting/consulting larger US based corporations that had the means to still get components and now we moved to completely software based projects for the moment. every know and then some hardware stuff but small stuff

2022-10-21T17:27:38 < Steffanx-> You're doing it wrong jbo. Here hw business is still on-going. Just some stuff has looooong lead times.
2022-10-21T17:28:55 < jbo> Steffanx-, yeah, it's usually likely that I do things wrong. hw business is going badly here.
2022-10-21T17:30:59 < Steffanx-> Not that clients are happy with the lead times obviously.
2022-10-21T17:31:50 < Steffanx-> Or when stuff gets brokered and their €70 product is €140 now
2022-10-21T17:31:53 < jbo> :LD
2022-10-21T17:31:56 < jbo> indeed
2022-10-21T17:32:02 < jbo> we have some germans waiting at the moment
2022-10-21T17:32:04 < jbo> for 14 months
2022-10-21T17:32:17 < jbo> not even stm32
2022-10-21T17:32:18 < jpa-> you can get triple the income by retargeting the same codebase to new CPUs every time one part runs out
2022-10-21T17:32:43 < Steffanx-> We did that jpa- :D
2022-10-21T17:32:44 < jbo> yeah, when stm32 became unavailable we noticed a spike in ugfx customers :D
2022-10-21T17:33:57 < karlp> my cpus are available, just not my regulators and isolators 
2022-10-21T17:34:41 < Steffanx-> China mcus karlp? 
2022-10-21T17:35:57 < karlp> no no

2022-10-21T19:20:30 < mawk> what's broken?
2022-10-21T19:20:43 < mawk> what's wrong in that paste Laurence_b ?
2022-10-21T19:20:48 < mawk> this ? 78      ../sysdeps/unix/syscall-template.S: No such file or directory.
2022-10-21T19:20:51 < mawk> that's normal
2022-10-21T19:21:39 < Laurence_b> the breakpoint is never hit again
2022-10-21T19:21:56 < Laurence_b> timer never fires again
2022-10-21T19:23:28 < Laurence_b> hmm maybe somehow it got set to zero
2022-10-21T19:23:34 < Laurence_b> hard to see how from that trace
2022-10-21T19:26:38 < Laurence_b> yeah I'm not seeing it
2022-10-21T19:26:51 < Laurence_b> its like the timer just died for no reason
2022-10-21T19:29:09 < Laurence_b> maybe there is memory corruption or something weird...

2022-10-21T22:36:17 < Steffanx-> The jeugd is probably from my younger years
2022-10-21T22:36:18 < jbo> not that it would change my state of caring for the genre

2022-10-23T17:10:33 < jbo> hello folks o/
2022-10-23T17:10:44 < jbo> all good?
2022-10-23T17:10:45 < benishor> anyone knows of a low power stm32 with 3 or 4 timers which I can use for reading encoders?
2022-10-23T17:10:47 < jpa-> hello mr. jelly bean officer
2022-10-23T17:11:12 < benishor> I was eyeing stm32l010 but that only has two timers
2022-10-23T17:11:13 < jbo> jpa-, how is that border of yours looking? all quiet?
2022-10-23T17:11:53 < jpa-> saw some people skinny dipping near the lot border this morning, but otherwise quiet
2022-10-23T17:12:22 < jbo> aye, good to hear
2022-10-23T17:16:37 < englishman> still worried about those swedes invading?
2022-10-23T17:17:34 < catphish_> benishor: how many encoders do you want to read?
2022-10-23T17:22:15 < catphish_> benishor: the chip you mentioned appears to have 3 x 16 bit timers with encoder mode, but i didn't check all the pin mappings, in any case i'd just work through the options in cube
2022-10-23T17:45:22 < qyx> if L010 is not enoigh, maybe try higher numbers or use parametric search on st.com?
2022-10-23T17:50:33 < jpa-> the total list of well-stocked STM32 models in non-BGA packages: L010, L011, F030, G031, L412, L433
2022-10-23T17:50:40 < jpa-> it doesn't take much effort to check them all
2022-10-23T17:50:56 < jpa-> picking an STM32 model has never been this easy
2022-10-23T17:54:11 < catphish_> L433 is my favourite chip because it can run USB with no external crystal, i might buy a few actually if they're in stock again
2022-10-23T17:56:20 < catphish_> you can do USB peripherals with almost no external parts
2022-10-23T17:57:23 < jpa-> digikey stock levels are funny, details page shows 0 stock for STM32L433 while listing page shows 7680 stock
2022-10-23T17:57:27 < catphish_> actually the L412 has that too, and even smaller
2022-10-23T17:59:29 < jpa-> or did catphish just buy them all ;)
2022-10-23T17:59:38 < catphish_> ooo L433 has CAN too, get in my basket :D
2022-10-23T18:00:29 < Xogium> catphish_: stop buying all the chips ! :p
2022-10-23T18:00:58 < Xogium> jpa-: maybe catphish_ is the origin of the chip shortage
2022-10-23T18:01:01 < Xogium> ^^
2022-10-23T18:01:15 < Xogium> naaah just kidding
2022-10-23T18:01:17 < catphish_> i see no L433 stock on mouser or farnell :(
2022-10-23T18:02:42 < Xogium> maybe someone did indeed buy them all
2022-10-23T18:03:24 < catphish_> they're available on digikey, expensive though :(
2022-10-23T18:04:04 < catphish_> https://www.digikey.co.uk/en/products/detail/stmicroelectronics/STM32L433RCT3/8257916 << great chip if you can afford one :D
2022-10-23T18:05:02 < catphish_> i used it in my USB floppy controller project a couple of years ago, as i said, crazy simple for a USB peripheral, and now i realise it has CAN too which would make it super cool for car stuff, except i'm done with that
2022-10-23T18:06:01 < Xogium> oh boy floppy
2022-10-23T18:06:14 < Xogium> brings back memories, that does
2022-10-23T18:07:01 < Xogium> I still have some of those around lol
2022-10-23T18:07:09 < Xogium> I've absolutely no clue what they store

2022-10-23T18:30:04 < catphish_> Xogium: my floppy controller was designed to read and write disks of legacy formats (like amiga) using a PC, mostly because i had an amiga and wanted to be able to download games, write them to disk, and play them
2022-10-23T18:31:09 < catphish_> it worked but i abandoned the project because it transpired that someone else was working on *exactly* the same project at the same time so i just contributed to his instead
2022-10-23T18:31:46 < kaki> hsnt it been done by the community like 100times?
2022-10-23T18:32:35 < catphish_> perhaps, though i'm only aware of 2 projects, one was based on a PCI card, and then this new one which is USB
2022-10-23T18:36:42 < catphish_> this is the project that i abandoned mine in favour of: https://github.com/keirf/greaseweazle - the developer also happens to be the original author of xen
2022-10-23T18:36:56 < Xogium> nice
2022-10-23T18:37:40 < catphish_> that's quite cool anyway, an STM32 that sits between USB and a standard floppy drive, then it can read/write raw data in any legacy format
2022-10-23T18:38:17 < catphish_> nice for archiving (and pirating) ancient games mostly

2022-10-23T19:20:51 < Xogium> hehe yeah
2022-10-23T19:21:20 < Xogium> I idly wonder if it could figure out how cpm based systems wrote info on the floppy disks...
2022-10-23T19:22:10 < Xogium> friend of mine is toying around with an old, probably first computer made for the blind, that was based on cpm, except that instead of having 3 drives for the whole system it was stored on 3 eeprom
2022-10-23T19:22:37 < Xogium> but it used floppy for user data, documents and the likes
2022-10-23T19:22:52 < Xogium> weirdly enough, even linux refuses to read such floppy, claiming they have no id
2022-10-23T19:24:38 < Xogium> my guess is they either stored the info without any kind of fs, or made their own. Like raw blob of data
2022-10-23T19:26:30 < Xogium> he even has the whole reference manual for the system, and in there they describe a little how things were formatted.. 80 tracks on each floppy, 40 per side, 4 first tracks reserved for file allocation table
2022-10-23T19:26:35 < Xogium> the rest was free to use
2022-10-23T19:26:51 < jpa-> linux is not very adept at reading anything other than standard PC floppies
2022-10-23T19:27:05 < Xogium> yeah, so it seems
2022-10-23T19:27:37 < Xogium> this thing is so ancient it used a 8085 processor andhad 8080 assembler :D
2022-10-23T19:27:46 < Xogium> *and a
2022-10-23T19:27:54 < Xogium> oh, and yes. It still works
2022-10-23T19:29:00 < Xogium> I'm sure someone could dump the roms and emulate the system on a pc these days

Messing about in memory regions with basic. I guess the hardware was badly design and you could potentially seriously mess it up writing to memory regions you weren't supposed to touch

2022-10-23T22:25:19 < upgrdman> any workworkers in here? i need to dado some strips of wood, but i dont have a router. how stupid would it be to use a drill press + fence + tounge-and-groove router bit?
2022-10-23T22:26:01 < kaki> strips?
2022-10-23T22:26:13 < kaki> elaborate further
2022-10-23T22:26:37 < qyx> isn't drill press like one or two order of magnitude slower?

2022-10-23T22:27:00 < qyx> my router is > 20krpm, drill press is about 500-1500 rpm
2022-10-23T22:27:25 < qyx> it could work, although very slow

2022-10-24T00:21:37 < catphish> what are sane options for connecting IoT devices to interwebs these days? zigbee + hub? wifi chips?
2022-10-24T00:23:20 < kaki> esp32
2022-10-24T00:24:17 < catphish> esp32 would certianly be my default? is that likely the best wifi option? i think i prefer wifi over zigbee because of flexibility, but seems like a mild pain to configure initially
2022-10-24T00:24:28 -!- GenTooMan [~cyberman@c-73-214-106-63.hsd1.pa.comcast.net] has joined ##stm32
2022-10-24T00:24:57 < kaki> zigbee for home automation gadgets and also if running from battery
2022-10-24T00:25:15 < kaki> sensors, switches that don't need wiring etc.
2022-10-24T00:25:25 < BrainDamage> for direct to interwebs wifi is better, zigbee is better if the device should work standalone because it will mesh with others
2022-10-24T00:25:37 < BrainDamage> and can even p2p binding eg a switch to a lamp
2022-10-24T00:25:43 < catphish> i keep thinking i want to build some kind of iot, but haven't decided what yet, i was thinking primarily along the lines of sensors, switches, relays, that kind of thing
2022-10-24T00:25:57 < kaki> what was the name of zigbee nowdays?
2022-10-24T00:26:22 < BrainDamage> zigbee is still zigbee, but there is a new thing from the same authors called matter
2022-10-24T00:26:39 < BrainDamage> but that is pretty much only a spec, came out few months ago
2022-10-24T00:26:55 < BrainDamage> also, likely going to be a nightmare to search for
2022-10-24T00:26:56 < catphish> i know very little about zigbee, is there like a standard say to say "hi zigbee network i'm a switch" and then lamps know how to interop with you because they know what a switch does?
2022-10-24T00:27:09 < BrainDamage> yes
2022-10-24T00:27:18 < catphish> well that sounds good
2022-10-24T00:27:24 < catphish> i realise i'm a little late to the party
2022-10-24T00:27:33 < catphish> but always fancied building this kind of stuff
2022-10-24T00:28:07 < catphish> is there an obvious choice of IC/module for that?
2022-10-24T00:28:24 < BrainDamage> theres some from TI
2022-10-24T00:28:30 < BrainDamage> sec
2022-10-24T00:29:15 < karlp> cool, went to the effort of building this P1 hardware.  seems like the port isn't (yet?) enabled on the meters...  just no data coming out at all. :|
2022-10-24T00:29:57 < BrainDamage> https://www.ti.com/product/CC2652R this is one, there is a few other from the same family
2022-10-24T00:30:19 < BrainDamage> oh, wow, they already added matter
2022-10-24T00:32:22 < karlp> matter is the old "chip" which was also an unsearchable name.
2022-10-24T00:32:53 < catphish> that looks nice, wonder if i can buy as module if i'm too incompetent to design the RF and solder the QFN?
2022-10-24T00:32:55 < karlp> silabs and st radios have support too.
2022-10-24T00:33:18 < BrainDamage> yes, there is the usual castellated modules you can slap on
2022-10-24T00:33:47 < catphish> yummy
2022-10-24T00:36:39 < catphish> i guess with such a MCU, STM32 is probably redundant
2022-10-24T00:38:26 < karlp> well, stm32wb is the radio, with ~an L4 inside...
2022-10-24T00:41:02 < BrainDamage> catphish the coordinator is necessary to add new items to the network, to tell one device to bind to another, and to interface with the wifi/interwebs
2022-10-24T00:41:20 < BrainDamage> for everything else, it can be literally offline, and the network will still work independently
2022-10-24T00:41:45 < BrainDamage> generally, each non battery powered device will act as a router, relaying traffic in the mesh
2022-10-24T00:43:07 < BrainDamage> I recommend getting a generic coordinator, and control it with zigbee2mqtt or similar
2022-10-24T00:43:41 < BrainDamage> the vendor coordinators have the bad tendency to refuse other brands devices, despite the standard fully supporting interoperation
2022-10-24T00:44:43 < catphish> BrainDamage: in my house right now i have some philips lights and switches, and their hub that lets me link and program things with their app, so i sort of understand how it works
2022-10-24T00:51:23 < BrainDamage> unrelated, this is quite neat: https://transparency.entsoe.eu/dashboard/show
2022-10-24T01:00:12 < catphish> i like this one (Uk specific) https://grid.iamkate.com/

2022-10-24T01:09:41 < catphish> yes he pulled out (yes that's funny because of reasons)
2022-10-24T01:09:53 < kaki> why he did that?
2022-10-24T01:10:14 < catphish> the same reason he resigned in the first place
2022-10-24T01:10:32 < kaki> that is what?
2022-10-24T01:10:45 < catphish> it's not "appropriate" for him to be the prime minister, because of misconduct / disrepute
2022-10-24T01:11:38 < Mangy_Dog> also the whole... he was probebly lying about having enough backers

2022-10-24T16:44:40 < jpa-> what kind of VAT issues do you have?
2022-10-24T16:45:00 < drzacek_> someone called?
2022-10-24T16:45:12 < qyx> sorted out now, they are not adding 21% VAT to the order
2022-10-24T16:45:21 < drzacek_> me just bought few stm32 for a fair price
2022-10-24T16:45:27 < qyx> they responded they will add it correctly after the order is placed
2022-10-24T16:45:53 < qyx> but thats weird and unusual, you are confirming an order with 0% VAT
2022-10-24T16:46:39 < jpa-> farnell is weird and unusual in many ways.. they send 4 separate invoices for 1 order and a truck full of packages
2022-10-24T16:47:08 < drzacek_> they might source from different warehouses, maybe?
2022-10-24T16:47:30 < fenugrec> surely they can't beat avnet at that game
2022-10-24T16:47:38 < qyx> farnell is avnet now
2022-10-24T16:47:41 < fenugrec> 5 boxes for a 35$ order is my personal best
2022-10-24T16:47:42 < qyx> maybe thats the reason
2022-10-24T16:47:42 < jpa-> IIRC in finland farnell doesn't even sell to people without VAT number
2022-10-24T16:47:47 < fenugrec> o I thought it was == newark
2022-10-24T16:48:10 < drzacek_> farnell belongs to avnet
2022-10-24T16:48:28 < drzacek_> and avnet has weird way of doing things
2022-10-24T16:49:15 < qyx> jpa-: I have a VAT number, but I don't pay VAT on my own, idk how are those economy things called properly in proper languages
2022-10-24T16:49:42 < drzacek_> qyx, what data request? what did I miss?
2022-10-24T16:49:43 < qyx> so I buy with a VAT added, much less paperwork for me later

2022-10-24T16:49:59 < drzacek_> link wont open
2022-10-24T16:50:05 < qyx> werent you the one with that weird request?
2022-10-24T16:50:16 < qyx> asserting a data request line before sending data over an UART
2022-10-24T16:50:20 < qyx> indeed it does

2022-10-24T16:51:11 < drzacek> oh I am weird alright, but which one?
2022-10-24T16:51:43 < jpa-> qyx: ok, interesting that they are willing to do that
2022-10-24T16:51:59 < qyx> I guess they have to
2022-10-24T16:52:07 < jpa-> i wouldn't bother if i was selling something to business only customers
2022-10-24T16:52:21 < qyx> yeah but I am business customer
2022-10-24T16:52:21 < karlp> the asserting isn't a problem really, it can just be tie dhigh, as long as it's tied high it's meant to repeat the messages every second.
2022-10-24T16:52:36 < karlp> I just wanted to be able to disconnect and connect, to "reset" things if I needed.
2022-10-24T16:52:40 < jpa-> i find VAT reverse charge easier, both as buyer and as seller

2022-10-24T17:12:02 < zyp> for me it doesn't really matter whether I pay VAT at time of purchase, pay VAT at time of import or just have the importer file it as VAT owed
2022-10-24T17:13:01 < zyp> it's just a matter of picking the right option from a dropdown when I file the invoice(s), and then it settles out to the same after the VAT settlement
2022-10-24T17:14:48 < zyp> generally all VAT my company pays is deductible, so I'm getting back anything I've paid, and in the case it's just filed as owed, it settles out to zero

2022-10-24T22:02:13 < catphish> karlp: perhaps my example wasn't clear enough, the pmos pulls the line high (when it's input it low) or lets it float (when its input is high), the source on the right was purely for demonstration purposes
2022-10-24T22:03:17 < catphish> (the 100Hz signal was just to demonstrate that the line line can do whatever it wants when the mosfet isn't pulling it high)

2022-10-25T15:16:43 < BrainDamage> the reason why they do it is that they go by the absolute imperative of not breaking muscle rythm
2022-10-25T15:17:13 < BrainDamage> ofc ending up in the hospital would be because they more more than just that, but that doesn't stop them being irresponsible

2022-10-25T17:03:51 < karlp> sure. you might want i2c pullups.

2022-10-25T17:52:29 < karlp> according to ST, you don't need the cap and resistor on rst, iirc.

2022-10-25T20:25:57 < bitmask> over 3000 have been delivered
2022-10-25T20:32:52 < karlp> well, a) it was delivered, functional to the field in 2013, and b) military contracting... maths doesn't always make sense.
2022-10-25T20:33:14 < rustyaxe> b is the main reason
2022-10-25T20:33:48 < rustyaxe> if you know someone will buy 3k of then at 200k$ - it beats trying to sell 600k of em at 2k$ lol
2022-10-25T20:34:45 < machinehum> I bet the company that developed them had tight restrictions
2022-10-25T20:35:03 < jpa-> could be that it has custom asics to integrate everything, would easily cost a lot for the first few thousand units

2022-10-25T20:36:21 < karlp> the costs are including development.
2022-10-25T20:36:39 < karlp> so yeah, military, but also, that was cutting edge
2022-10-25T20:48:30 < rustyaxe> they are tiny for sure. Im just saying why chase trying to sell a shite ton of em to people cheap when you can do a much more managable run at DOD prices? :P

2022-10-25T22:06:09 < kraiskil> I have a bare skeleton project set up by STM32CubeMX. Works fine, but when debugging/stepping through it, it fails in the RCC setup.  
2022-10-25T22:06:23 < kraiskil> I'm completely lost, any hints appreciated :)
2022-10-25T22:10:48 < catphish> kraiskil: well since you're stepping through, can you see exactly where it fails?
2022-10-25T22:11:17 < catphish> i'm not familiar with template projects from cube though sadly
2022-10-25T22:11:38 < qyx> sounds like your RCC setup is wrong then?
2022-10-25T22:12:50 < kraiskil> the RCC setup is generated by STM32Cube, and I didn't touch it. Uses the HSI, so it should be ok. Looking at the registers, it seems like the write to RCC_CFG has failed.
2022-10-25T22:13:22 < kraiskil> But I don't really know if this is because of the debugger, the STM32HAL, or me not understaning something
2022-10-25T22:14:42 < kraiskil> s/RCC_CFG/RCC_PLLCFGR/
2022-10-25T22:15:46 < qyx> PLL may be out of range, VDD may be out of range (flash wait states configured wrong)
2022-10-25T22:16:02 < kraiskil> I.e. decoding the bits in RCC_PLLCFGR do not match the values the STM32HAL function call is supposed to write 
2022-10-25T22:16:23 < kraiskil> qyx: flash wait states? This is new stuff for me...
2022-10-25T22:16:45 < kraiskil> and the target is a STM32Nucleo board, so the HW should be sound :D
2022-10-25T22:17:28 < qyx> if a default cube project fails on a vendor devboard, I would call the vendor
2022-10-25T22:17:40 < qyx> although you can still debig it
2022-10-25T22:17:47 < kraiskil> lol! 
2022-10-25T22:17:58 < kraiskil> yeah, anyone got ST's number :p
2022-10-25T22:18:22 < qyx> hey your cubez are wrong
2022-10-25T22:18:42 < qyx> but sorry, no cube experience
2022-10-25T22:18:49 < kraiskil> ST make such beautiful HW...
2022-10-25T22:19:44 < kraiskil> yeah... I'm trying to gain some. But the more I play around with this, the more I think this CubeMX/HAL tools just slow me down instead of the promised speedup :D
2022-10-25T22:23:57 < kraiskil> If I in gdb say "load" then "monitor reset init", the RCC_PLLCFGR readback fails. But if I say 'monitor reset init', then 'load', it works...
2022-10-25T22:24:24 < kraiskil> I'm thinking the problem is me not understanding openocd :D
2022-10-25T22:26:00 < PaulFertser> kraiskil: what bit of information are you missing from the OpenOCD manual?
2022-10-25T22:27:58 < kraiskil> PaulFertser, if I knew that, I could look it up :D And to be fair, the problem could equally well be in my system, gdb or target understaning :)
2022-10-25T22:28:27 < kraiskil> Just trying to probe people for some comment that would lead to an insight for me here
2022-10-25T22:29:29 < kraiskil> the gdb 'load' command, that loads the elf to RAM, not flash, right?
2022-10-25T22:30:07 < kraiskil> so 'monitor reset init' causes the code to be run from flash, not RAM? 
2022-10-25T22:30:24 < kraiskil> why would this make a difference?
2022-10-25T22:40:19 < specing> <PaulFertser> specing: there was a famous case when putin showed footage from some computer game claiming it's russian operations in Syria.
2022-10-25T22:40:32 < specing> PaulFertser: propaganda working without anyone having to die for it? Impressive
2022-10-25T22:43:24 < pragmalin> kraiskil, I would try with STM32CudeIDE as your IDE. The new project wizard then generated the debugger configuration for you and you won't have to deal with OpenOCD.
2022-10-25T22:44:22 < kraiskil> pragmalin, thanks. What does STM32CubeIDE use as the debug connection tool then?
2022-10-25T22:44:55 -!- catphish__ [~charlie@user/catphish] has quit [Remote host closed the connection]
2022-10-25T22:46:00 < pragmalin> kraiskil, is used the ST-Link GDB server. A tool that is installs automatically together with the STM32CubeIDE. It also includes CubeMX, so you can do everything from the IDE.
2022-10-25T22:46:24 < pragmalin> kraiskil, typos: is=it
2022-10-25T22:47:17 < kraiskil> right, maybe I should give it a go. Installing ST tools is just such a PITA because of the licensing stuff I tend to go with other options whenever possible :D
2022-10-25T22:47:52 < kraiskil> though I'd still like to understand what the heck is going on here :D
2022-10-25T22:48:03 < PaulFertser> kraiskil: gdb load will load to flash if your ELF has addresses of the flash in it.
2022-10-25T22:48:46 < PaulFertser> specing: unfortunately, all those silly cartoons kinda prepared the russian society to a real war I'm afraid.
2022-10-25T22:49:17 < specing> PaulFertser: was the 2008 one unreal?
2022-10-25T22:49:49 < kraiskil> PaulFertser, thanks. But that just makes this even more confusing to me :D
2022-10-25T22:50:02 < PaulFertser> kraiskil: you do not need to do "monitor reset init" just about ever, as the reset-init handler is specific for OpenOCD operations such as flash programming etc, and it ramps up PLL on HSI for certain targets.
2022-10-25T22:50:09 < kraiskil> So its the 'monitor reset init' that messes things up? 
2022-10-25T22:50:16 < PaulFertser> kraiskil: after "load" you can just set whatever breakpoints you want and "continue".
2022-10-25T22:50:47 < PaulFertser> specing: it was real indeed :( but it was relatively contained.
2022-10-25T22:50:53 < kraiskil> PaulFertser, but how do I restart the target if not with 'monitor reset init'
2022-10-25T22:52:22 < kraiskil> I mean I've been doing that for the better part of a few decades. Muscle memory needs updating :D
2022-10-25T22:52:23 < PaulFertser> kraiskil: you can use "run" or "start" GDB commands. If you insist on going low level, you can use "mon reset halt".
2022-10-25T22:52:41 < PaulFertser> start is "tb main" "run" essentially.
2022-10-25T22:53:56 < PaulFertser> kraiskil: so if you want to debug from the very first instruction of the reset vector you can do "mon reset halt" "mon gdb_sync" "si"
2022-10-25T22:54:07 < kraiskil> "The "remote" target does not support "run"."
2022-10-25T22:54:27 < kraiskil> break at main() should be sufficient for noe
2022-10-25T22:54:36 < kraiskil> s/noe/now
2022-10-25T22:54:59 < PaulFertser> kraiskil: use "tar ext :3333", not just "remote".
2022-10-25T22:56:18 < kraiskil> PaulFertser, hey, that works. Thanks!
2022-10-25T22:56:53 < kraiskil> so just for my understanding, what is the difference between target remote and ext?
2022-10-25T22:59:00 < PaulFertser> kraiskil: (ext) extended-remote just allows few more commands in the GDB serial protocol. OpenOCD supported them since very long, there's zero reason to not use them.
2022-10-25T23:02:20 < kraiskil> PaulFertser, thanks. Duly noted. I'll read up on those low level commans. If only to remember I should not need them :D

2022-10-26T00:17:20 < karlp> and no... 
2022-10-26T00:17:55 < karlp> still, 10k _is_ apparently too high, whatever resistor inside  on the opto is definitely happier with shorting to 5v, so it gets the specced current, but... nod ata.
2022-10-26T00:17:57 < karlp> no data.
2022-10-26T00:18:13 < karlp> and the distrib company says the P1 ports will be enabled "end of 2022" so its just not there yet...
2022-10-26T00:18:16 < karlp> what a waste of time :)
2022-10-26T00:26:52 < qyx> icelandic distrib company
2022-10-26T00:27:16 < qyx> hm, maybe I should read something about your electrification
2022-10-26T00:36:03 < BrainDamage> at least you have a port at all
2022-10-26T00:36:25 < BrainDamage> here there's a ir iface, but you're not allowed to wire anything to it
2022-10-26T00:36:59 < BrainDamage> even using the blipping led's that's proportional to consumption is frowned upon

2022-10-26T11:52:36 < benishor> good morning, people of earth
2022-10-26T11:53:56 < jpa-> good morning, ben of ishor
2022-10-26T12:00:08 < benishor> and how is finland this very fine morning, milord?
2022-10-26T12:05:03 < karlp> not allowed to wire to the led? on what grounds? that's it's purpose!
2022-10-26T12:05:32 < karlp> I have been told by kamstrup that "no, no, no, NO, you are NOT meant to permanently talk to the IR interface! that's got an internal battery that you're killing!"
2022-10-26T12:05:54 < karlp> which seemed..... dumb as fuck, but not my party.
2022-10-26T12:22:07 < qyx> what?
2022-10-26T12:30:19 < karlp> exactly that. 
2022-10-26T12:30:56 < karlp> the IR interface on some of their meters is apparently powered by it's own battery, allegedly, and is only intended to be used by the manual meter reader person, not 24/7.
2022-10-26T12:35:31 < karlp> ask quectel contact to explain all the extra numbers and letters in order codes..... completely ignores question, just says, "use this order code..."
2022-10-26T12:37:02 < qyx> I am very curious what's that grumpiness state induced with
2022-10-26T12:37:11 < qyx> I am dealing with such things and people every day
2022-10-26T12:37:44  * karlp didn't notice he was particularly grumpy, but perhaps more than normal. sorry.
2022-10-26T12:38:06 < karlp> I sitll am surprised that braindamage says they're nota llowed to even watch the blinking usage led, as that is literally what it's for.
2022-10-26T12:38:17 < qyx> the last one was "why aren't those rails stainless, they were quoted stainless, paid for inox"
2022-10-26T12:38:25 < qyx> "oh isn't it a prototype?"
2022-10-26T12:38:47 < qyx> sorry, *paid for stainless
2022-10-26T12:38:52 < karlp> and that should have made you grumpy?
2022-10-26T12:39:12 < karlp> or are you an icon of stoicness, and just move on in bliss?
2022-10-26T12:39:46 < qyx> sometimes it is meh, but not anymore when it repeats
2022-10-26T12:46:30 < qyx> oh but on a brighter side, mouser has arrived
2022-10-26T12:46:39 < qyx> with some missing components for my STM32MP1 board
2022-10-26T12:47:02 < qyx> so I have to tidy up the table and find few hours to try it again
2022-10-26T13:15:17 < karlp> bleh, tired to use the beta-tools.analog.com/noise/ tool to try it out, but it's all got busted CORS and doesn't load.
2022-10-26T13:15:32 < karlp> "security" making the world better, minus one day at a time.
2022-10-26T13:29:37 < karlp> in other fun stuff, check out the quality 3d model here: https://app.ultralibrarian.com/details/55E2E7C9-1073-11E9-AB3A-0A3560A4CCCC/Taiyo-Yuden/NR5040T3R3N?ref=digikey
2022-10-26T13:30:04 < karlp> linked from https://www.digikey.com/en/products/detail/taiyo-yuden/NR5040T3R3N/2178890 which has a pretty decent view of the part
2022-10-26T13:32:41 < karlp> huh, chilisin is now part of yageo/pulse.
2022-10-26T13:36:16 < qyx> I usually just use IHLPxxxx 3d models

2022-10-26T15:53:10 < BrainDamage> karlp: you're not allowed to attach anything to the meter, the official excuse is to prevent tampering, the reality is because they attempted to sell remote monitoring, failed, and forbid any form of possibility I guess because they might try again in the future
2022-10-26T15:54:26 < qyx> attempt to sell remote monitoring?
2022-10-26T15:54:48 < qyx> aren't all in the EU required to *have* remote readout since 2023 or so?
2022-10-26T15:55:03 < qyx> it is quite common here, you even have a web interface for that
2022-10-26T15:55:15 < BrainDamage> this was ~5 years ago
2022-10-26T15:56:00 < BrainDamage> and remote readout is present in the meters since uh, I think 15 years, but no user access
2022-10-26T15:56:43 < qyx> hm yeah the user access thing is maybe only about 5y old
2022-10-26T15:57:28 < qyx> but it is still not flexible enough, you only get data in 15 minute intervals
2022-10-26T15:57:44 < srk> well if you sense blinking led from external device is that really attaching anything? it's optocoupled .. 
2022-10-26T15:58:07 < BrainDamage> physically attached
2022-10-26T15:58:46 < srk> attach it to the cabinet instead 
2022-10-26T15:59:10 < BrainDamage> it's on a wall with an array of my neighbours meters
2022-10-26T15:59:37 < qyx> is it PLC or GSM based?
2022-10-26T15:59:49 < BrainDamage> PLC, but it's encrypted
2022-10-26T15:59:59 < qyx> f*ck encryption
2022-10-26T16:00:02 < srk> well, split core transformer then :)
2022-10-26T16:00:37 < BrainDamage> I think I'll just end up installing my own meter
2022-10-26T16:00:40 < qyx> such misuse of encryption

2022-10-26T18:11:49 < benishor> even vectorize it
2022-10-26T18:12:11 < BrainDamage> they are likely vector images to begin with
2022-10-26T18:12:21 < BrainDamage> but decided to send raster
2022-10-26T18:15:17 < karlp> so they get jaggy text in their icon. I'm not chasing them for it :)

--- Day changed to loka 27 2022
2022-10-27T00:02:05 < karlp> bleh, tried to reproduce a weird kicad step export bug.  doesn't happen now :|
2022-10-27T00:16:00 < mawk> bitmask have you ever been on bupre
2022-10-27T00:16:04 < mawk> my doctor wants to put me on that
2022-10-27T00:16:12 < bitmask> yea
2022-10-27T00:16:24 < mawk> she says I have to be hospitalized for a week or so to change from 120mg methadone to bupre
2022-10-27T00:16:30 < mawk> it sounds lame
2022-10-27T00:16:40 < mawk> I don't like pain
2022-10-27T00:16:43 < bitmask> how are they gonna do it? switching is gonna suck
2022-10-27T00:17:17 < mawk> reduce methadone to 40mg over a week while giving me loads of benzos and sleep medication, then stop it for 3 days with even more medication, and then start the suboxone
2022-10-27T00:17:21 < mawk> I think
2022-10-27T00:17:32 < bitmask> i took bupe too early after using once and got precipitated withdrawals and thought I was gonna die for like 15 min and then it was over. pure projectile vomiting and couldn't breathe
2022-10-27T00:17:40 < mawk> I had that too
2022-10-27T00:17:55 < mawk> I took 48mg of bupre the day after the usual 300mg methadone dose
2022-10-27T00:18:05 < mawk> I was very close to calling 911, it lasted like that for two days
2022-10-27T00:18:22 < mawk> I slightly fucked up
2022-10-27T00:18:30 < bitmask> i prob didnt have much left to kick off the receptors so while it was bad, it wasnt for long
2022-10-27T00:18:46 < mawk> yeah
2022-10-27T00:18:57 < mawk> methadone lasts very long so the precipitated withdrawals do too
2022-10-27T00:19:06 < bitmask> ahh
2022-10-27T00:19:12 < mawk> but then some random guy on reddit told me to just take a shitload of heroin to cure the precipitated withdrawal so I did that and it kinda worked

2022-10-27T19:01:24 < kaki> C:\WINDOWS\system32>dmesg
2022-10-27T19:01:25 < kaki> 'dmesg' is not recognized as an internal or external command,
2022-10-27T19:01:25 < kaki> operable program or batch file.
2022-10-27T19:01:53 < Xogium> could be memory fragmentation aka being unable to allocate memory even for the tiniest task and resulting in super weird crashes that don't make sense
2022-10-27T19:02:00 < Xogium> ah
2022-10-27T19:02:05 < Xogium> this isn't linux lol
2022-10-27T19:02:43 < kaki> hey I had one time some "kernel security check failure"
2022-10-27T19:02:47 < Xogium> though I'm sure windows is also victim of memory fragmentation
2022-10-27T19:02:58 < kaki> it was something about some heap
2022-10-27T19:03:42 < Xogium> but afaik, ram tests are performed by filling the ram with random data then reading them back
2022-10-27T19:03:50 < mawk> if you're not on linux and you think that rebooting is a sin then you might want to reboot

2022-10-27T19:06:18 < PaulFertser> btw, memtest86+ GPL version 6.0 was recently released, it's like a complete rewrite, with UEFI support etc.
2022-10-27T19:06:36 < mawk> memtest86+ doesn't like my pc
2022-10-27T19:06:39 < mawk> I had to use the proprietary shite
2022-10-27T19:06:47 < PaulFertser> Give this release a try
2022-10-27T19:06:52 < PaulFertser> It's quite recent.
2022-10-27T19:06:53 < mawk> yeah
2022-10-27T19:09:30 < kaki> windows has memtest
2022-10-27T19:09:49 < kaki> first I upgrade bios though
2022-10-27T19:10:13 < kaki> every time I open [vendor] update there is critical bios update
2022-10-27T19:11:09 < kaki> half of the time they are fighting fires caused by intel
2022-10-27T19:12:06 < mawk> windows memtest is lame
2022-10-27T19:12:09 < mawk> try memtest86+
2022-10-27T19:12:16 < kaki> looks the same
2022-10-27T19:12:18 < mawk> if you only find a few bad addresses you can tell windows to ignore them
2022-10-27T19:12:27 < mawk> you need memtest86+ to know exactly which addresses are failing
2022-10-27T19:12:33 < kaki> blue textmode screen and some progress bar
2022-10-27T19:12:33 < mawk> that's what I did on my laptop
2022-10-27T19:12:46 < mawk> yeah but you need the full report at the end
2022-10-27T19:12:48 < mawk> to do something about it
2022-10-27T19:12:53 < mawk> unless you don't care and just buy new ram
2022-10-27T19:13:06 < mawk> I have exactly 1 stuck bit on my RAM on my laptop, so I modified windows registry to ignore the page where it is
2022-10-27T19:13:12 < mawk> and I also played the warranty to get a new stick
2022-10-27T19:13:17 < mawk> so now I have 64GiB and it works perfectly
2022-10-27T19:13:49 < kaki> my rams are soldered in
2022-10-27T19:13:58 < mawk> then you have no choice but ignore the bad address
2022-10-27T19:14:05 < mawk> so you need a full report of which address is bad

2022-10-27T22:35:53 < hexo> hm, whats wrong with it?
2022-10-27T22:35:58 < Laurence_b> lunix ppp supports MTU down to 128bytes, thats small enough for some of these radios
2022-10-27T22:36:03 < Laurence_b> really high overheads
2022-10-27T22:36:15 < Laurence_b> and bad fragmentation
2022-10-27T22:36:19 < hexo> :(
2022-10-27T22:36:26 < hexo> disconnects?
2022-10-27T22:36:33 < hexo> network partitioning?
2022-10-27T22:36:35 < Laurence_b> no just poor throughput
2022-10-27T22:36:58 < hexo> i've heard that zigbee has this partitioning problem
2022-10-27T22:37:13 < Laurence_b> and <128byte MTU so udp or tcp/ip gets fragmented
2022-10-27T22:37:14 < hexo> that it melts when you have more than about 20 nodes
2022-10-27T22:37:55 < Laurence_b> lunix will allow down to 128byte MTU, so if you can manage that with ppp you can mount _anything_ as a network interface on lunix
2022-10-27T22:38:35 < qyx> datalink for what
2022-10-27T22:38:38 < qyx> balloons?
2022-10-27T22:38:43 < Laurence_b> its supposed to be something that talks byte streams, but you can set the MTU to be small then intercept the HDLC packet headers to encapsulate it into the hardware packets
2022-10-27T22:38:46 < Laurence_b> maybe
2022-10-27T22:38:52 < qyx> and why 2psk?
2022-10-27T22:38:59 < Laurence_b> maximum performance
2022-10-27T22:39:06 < qyx> most of the transceiver support msk/gmsk
2022-10-27T22:39:08 < qyx> which is qpsk
2022-10-27T22:39:20 < catphish> 128 byte MTU isn't valid for internet traffic afaik :(
2022-10-27T22:39:34 < Laurence_b> AT86RF looks nice, but its 802.16.4
2022-10-27T22:39:38 < catphish> iirc min is supposed to be 512
2022-10-27T22:40:02 < Laurence_b> catphish: yeah but aiui lunix can be persuaded to play nice and do packet fragmentation at that size
2022-10-27T22:40:19  * qyx  running FreeRTOS on G4
2022-10-27T22:40:53 < catphish> oh yeah i guess you could do fragmentation, but eww
2022-10-27T22:41:40 < Laurence_b> yeah but the thing is
2022-10-27T22:41:52 < Laurence_b> it seems like that would be nicer than 802.16.4 + 6lowpan
2022-10-27T22:44:58 < qyx> what was the deal with STM32 and clipped sinewave oscilaltors?
2022-10-27T22:53:12 < Laurence_b> https://www.mouser.co.uk/ProductDetail/Renesas-Electronics/ZWIR4512AC1WI?qs=u8ePFVghNnQCysmEHhpnKw%3D%3D
2022-10-27T22:53:18 < Laurence_b> interesting but obselete
2022-10-27T23:00:18 < Laurence_b> spirit-1 packet mode also looks way smarter than 802.16.4
2022-10-27T23:03:26 < qyx> spirit1 is old too
2022-10-27T23:03:41 < qyx> and I think ST degoogled it
2022-10-27T23:03:48 < qyx> like it did with their wifi modules

2022-10-28T19:04:17 < jbo> got some PCB here with rather large relays (12V coil, 250VAC 50A rated). There is an SMD component parallel to each coil. The component is marked "BT 56A". A diode dest shows 0.3V voltage drop in both directions. having trouble finding a datasheet from the marking. any ideas?
2022-10-28T19:05:32 < jbo> it's a two-pad jobby
2022-10-28T19:05:50 < jbo> might be a TVS diode?
2022-10-28T19:09:54 < qyx> I would say the voltage drop is caused by the coil
2022-10-28T19:11:29 < jpa-> yeah, you are probably measuring the coil unless you desoldered the diode
2022-10-28T19:13:44 < jbo> yeah, just took the "diode" off
2022-10-28T19:13:49 < jbo> it shows open connection in both directions :D
2022-10-28T19:14:18 < jpa-> put your lab psu to 60V & 1mA or similar and see what it says
2022-10-28T19:14:20 < qyx> it is not dioding much
2022-10-28T19:14:21 < jbo> it's the relay board of a 3-phase solar inverter. apparently a lot of people had this thing breaking down and replacing the relay board helped. but that would be like a 250.- USD and currently unavailable, so trying to fix what is actually broken
2022-10-28T19:14:46 < jbo> jpa-, good idea. my bench DMM only has like 5 or 6V for diode testing afaik
2022-10-28T19:15:21 < jpa-> what size of package is it? SMA?
2022-10-28T19:15:49 < jpa-> and polarity line or no polarity line?
2022-10-28T19:16:40 < jbo> just did the bench supply thingy and still open in both directions
2022-10-28T19:16:53 < jbo> no polarization marking visible at all on this one
2022-10-28T19:17:07 < jbo> it's roughly SMA shaped, but I haven't done HW in a while so my knowledge might be off
2022-10-28T19:17:17 < jbo> the marking is   BT\n56  
2022-10-28T19:17:40 < jbo> and below that a company logo I don't recognize (like flower but with only four leaves)
2022-10-28T19:17:50 < jbo> leafs*  jesus
2022-10-28T19:18:21 < jbo> BT 56A that is, 
2022-10-28T19:18:25 < jpa-> isn't "leaves" correct? or does it have some cannabis jesus on it?
2022-10-28T19:19:20 < jbo> not important but this would be the board (random picture from the internet): https://http2.mlstatic.com/D_735392-MLB48746748437_012022-B.jpg
2022-10-28T19:22:20 < jbo> so there are four relays, each of them has one of "these". but there is also a diode across the coil of each relay
2022-10-28T19:23:56 < jpa-> so, at least that part is not stopping anything from happening

2022-10-28T19:33:44 < jbo> testing the rest of the circutry, but the board seems to perform as expected on first glance (at least without load)
2022-10-28T19:37:10 < jpa-> looks like simple enough board to clone, so you can start selling it as second source
2022-10-28T19:38:00 < jbo> hehe, yeah, but that's not my style I guess
2022-10-28T19:38:14 < jbo> plus it's an ABB jobby, they'd probably kick down my door
2022-10-28T19:40:33 < karlp> why doesn't phoenix have a recommended case cut sizes for things that get plugs with clips over the top?

2022-10-28T22:29:36 < rustyaxe> https://istabpeople.com/junk/b00m.jpg that is what it looks like in action. It makes freedom ring

2022-10-28T22:30:03 < rustyaxe> It is 308 winchester pistol

2022-10-28T22:30:11 < rustyaxe> Sometimes .357 magnum is not enough
2022-10-28T22:30:38 < kaki> that round is rifle round
2022-10-28T22:31:29 < kaki> how is the recoil?
2022-10-28T22:31:41 < rustyaxe> Its not too bad. It weighs about 5lb
2022-10-28T22:32:21 < kaki> does that gun have any practical purpose?
2022-10-28T22:32:54 < rustyaxe> Hunting deer. Shooting home invaders wearing soft armor. Generally most people cease their poor behaviour when you unholster it too.
2022-10-28T22:33:22 < rustyaxe> If you miss, it still has a good chance to make them on fire at moderate ranges :O

2022-10-28T23:01:46 < rustyaxe> But the cop who stopped me said i hit 61mph in the 55 and he wasn't mad just impressed. :P
2022-10-28T23:02:07 < catphish> today i drove a tesla roadster :D
2022-10-28T23:02:19 < rustyaxe> did you wash yourself with bleach afterwards?
2022-10-28T23:03:10 < catphish> i did not, it was awesome

2022-10-28T23:08:42 < rustyaxe> Sorry about that :(

2022-10-28T23:09:46 < PaulFertser> Do you actually review them? Or was traffic consumption reduced?
2022-10-28T23:10:44 < rustyaxe> My log console stopped scrolling by like world was ending within minutes of adding the ipsets :\
2022-10-28T23:11:03 < rustyaxe> they were beating my poor smtpd to hell and back

2022-10-29T00:22:36 < mawk> bitmask do you have narcan with you?
2022-10-29T00:22:43 < mawk> a reddit guy wants to send me a box of it
2022-10-29T00:22:53 < mawk> that sounds illegal but I'll say yes
2022-10-29T00:23:24 < bitmask> i got a few from the methadone clinic when i first started, they expired so im pretty sure i tossed them 
2022-10-29T00:24:29 < Steffanx-> Mawk and his drug addiction -_-
2022-10-29T00:24:53 < mawk> it probably doesn't expire
2022-10-29T00:24:59 < mawk> but it's in solution so I don't know 
2022-10-29T00:25:02 < mawk> it's not drug Steffanx- 
2022-10-29T00:25:06 < mawk> it's anti-drug 
2022-10-29T00:25:14 < mawk> it's the antidote to opiates
2022-10-29T00:25:23 < mawk> that you give to people overdosing so that they don't die
2022-10-29T00:25:38 < Steffanx-> So why you need it then?
2022-10-29T00:25:53 < mawk> to revive overdosing friends
2022-10-29T00:26:07 < mawk> or revive sneaky guests if they go through my methadone stash
2022-10-29T00:26:10 < mawk> or kids
2022-10-29T00:26:18 < mawk> or revive the cat if she eats a pill
2022-10-29T00:26:25 < mawk> or revive myself if I fuck up
2022-10-29T00:26:31 < mawk> not dying is pretty cool 
2022-10-29T00:27:06 < Steffanx-> Don't fuck up 
2022-10-29T00:27:14 < mawk> better safe than sorry
2022-10-29T00:27:38 < Steffanx-> No need to be sorry after overdosing.
2022-10-29T00:27:43 < mawk> why
2022-10-29T00:27:54 < mawk> that depends if it's voluntarily or not
2022-10-29T00:28:30 < mawk> and even when it's voluntary we tend to try to revive people that tried to die
2022-10-29T00:29:02 < Steffanx-> No need to be sorry when you, when you dont survive it
2022-10-29T00:29:20 < Steffanx-> -when you
2022-10-29T00:29:22 < Steffanx-> Lol
2022-10-29T00:29:32 < mawk> sure
2022-10-29T00:29:38 < mawk> but people are me will be sad
2022-10-29T00:29:43 < mawk> also I like being alive
2022-10-29T00:29:46 < mawk> I'm not done here
2022-10-29T00:29:57 < rustyaxe> It's evolution, baby!
2022-10-29T00:30:11 < mawk> only when I can sleep with my childhood love I can die happy
2022-10-29T00:30:19 < mawk> or maybe when I do something useful for the world 
2022-10-29T00:30:21 < mawk> not before 
2022-10-29T00:30:53 < rustyaxe> Human extinction? That seems useful for the world
2022-10-29T00:32:18 < mawk> if it happens after my time it's fine

2022-10-29T17:06:38 < kaki> yes
2022-10-29T17:12:08 < kaki> imagine the horror of the employees of twitter
2022-10-29T17:13:31 < specing> I don't understand why he has to buy tweeter if he intends to fire lots of people. He could just make a tweeter competitor
2022-10-29T17:16:02 < kaki> didn't trump try that?
2022-10-29T17:16:11 < kaki> yet another echo chamber

2022-10-29T17:24:03 < specing> kaki: yeah but trump has no money
2022-10-29T17:24:12 < specing> musk could actually run ads for his tweeter v2.0

2022-10-29T19:14:55 < Laurence_b> hmm maybe stm32 can do this
2022-10-29T19:40:13 < qyx> yes fully digital, modulator on the primary side, digital isolator, stm32 with that DSFDM
2022-10-29T19:41:07 < Laurence_b> I need bidirectional tho, and stm32 cant modulate?

2022-10-29T23:42:16 < kaki> normal means like local weather related etc.
2022-10-29T23:42:25 < kaki> in my books
2022-10-29T23:49:08 < Steffanx-> I dont even remember the last power outage not caused by myself here.
2022-10-29T23:50:37 < qyx> we are in a power saving mode now
2022-10-29T23:50:48 < qyx> 5 days with no photovoltaic gain
2022-10-29T23:51:07 < qyx> 1.5kWh daily
--- Day changed su loka 30 2022
2022-10-30T00:27:07 < BrainDamage> how much average power do you draw?
2022-10-30T00:27:22 < BrainDamage> I ballparked mine to 300W or so
2022-10-30T00:31:59 < qyx> around 2 kWh daily
2022-10-30T00:32:03 < qyx> so under 100 W
2022-10-30T00:32:58 < qyx> depends, but it can be 3 kWh or up to 5 kWh
2022-10-30T00:52:04 < rustyaxe> i use 263kwh/month

2022-10-30T07:59:11 < machinehum> qyx: Yeah, that's what I figure
2022-10-30T07:59:33 < machinehum> But you would need a feedback loop
2022-10-30T08:00:15 < machinehum> It would basically be 3 parts, the pwm generator, transistor and fedback loop
2022-10-30T08:00:35 < machinehum> You could make the feedback loop a PID loop
2022-10-30T08:00:58 < machinehum> I'm very high and can't tell if that makes sense or not
2022-10-30T08:01:28 < machinehum> Oh I guess upi
2022-10-30T08:01:42 < machinehum> you're saying the comparator would be the feedback
2022-10-30T08:01:53 < machinehum> That might osicilate out of control

2022-10-30T17:36:54 < kaki> sounds like a jubb for entry level fpga
2022-10-30T17:42:58 < jpa-> esp32 has built-in sigma delta modulator
2022-10-30T17:43:05 < Laurence_b> kaki: yeah, esp32 is the only micro I've found that can do it
2022-10-30T17:43:20 < jpa-> pretty much any micro can do the same by software
2022-10-30T17:43:38 < Laurence_b> not at high speed, but then again esp32 is limited to 10MHz
2022-10-30T17:44:00 < Laurence_b> generating 10MHz 2nd order sigma-delta on stm32 would be v hard
2022-10-30T17:44:04 < jpa-> isn't ESP32 modulator just 8 bit also?
2022-10-30T17:44:10 < Laurence_b> no its 16bit
2022-10-30T17:45:13 < Laurence_b> I tried to work out how hard it would be with discrete logic, looks actually quite tricky, even an entry level cpld wouldn't do it
2022-10-30T17:45:40 < Laurence_b> esp32 motor controller is quite good too, pity the adc is so poor
2022-10-30T17:46:10 < Laurence_b> it doesnt have proper synchronisation modes to control the adc sampling either
2022-10-30T17:46:26 < Laurence_b> the timer is as good as tms320 lol
2022-10-30T17:51:01 < Laurence_b> actually the esp32 can run as a i2s stereo source, so the adc could be locked to timers with some external logic
2022-10-30T17:54:38 < jpa-> Laurence_b: hmm, which ESP32 has 16-bit general purpose sigma delta? e.g. ESP32C3 shows the GPIOSD_SIGMADELTAx_REG data width as 8-bit
2022-10-30T17:55:08 < jpa-> then there is the 16-bit PCM->PDM converter as part of the I2S block, but i think that is just single channel

2022-10-30T18:02:28 < Laurence_b> hmm ok
2022-10-30T18:02:34 < Laurence_b> I read it as 16bit dual channel
2022-10-30T18:03:17 < Laurence_b> https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/peripherals/i2s.html
2022-10-30T18:03:41 < Laurence_b> "PDM TX can only support 16 bits width sample data"
2022-10-30T18:03:49 < Laurence_b> or do they mean dual 8bit?
2022-10-30T18:06:11 < jpa-> that is the I2S PDM
2022-10-30T18:06:36 < jpa-> maybe it is two channel then
2022-10-30T18:07:14 < jpa-> usually in I2S PDM the left / right are interleaved on single pin
2022-10-30T18:07:21 < Laurence_b> wait there is another sigma-delta thing
2022-10-30T18:07:47 < jpa-> yes, there is 8-bit GPIO PDM which you use for blinking leds, and there is 16-bit I2S PDM you use for making beeps
2022-10-30T18:09:27 < jpa-> to me the I2S PDM appears to have only one output pin, even though it can interleave two stereo channels on it
2022-10-30T18:09:41 < jpa-> i guess you could separate them if you are really desperate
2022-10-30T18:09:54 < jpa-> with e.g. two D-flipflops or something
2022-10-30T18:11:31 < Laurence_b> yeah
2022-10-30T18:13:18 < jpa-> i don't quite see why you consider second order sigma delta so difficult, it seems it would be quite easily done at 10MHz on any >= 100MHz cortex-m3
2022-10-30T18:14:26 < Laurence_b> if you try to work out all the instructions required its quite demanding
2022-10-30T18:14:42 < Laurence_b> also using 100MHz of your available clock cycles for modulation is not good

2022-10-30T18:15:14 < jpa-> yeah, might want to use a 400MHz processor if you have several channels and other things to do
2022-10-30T18:16:03 < jpa-> i agree that hardware support is nice, but 8-bit seems quite useless
2022-10-30T18:16:12 < jpa-> PWM is pretty much as good at such bit depths
2022-10-30T18:16:12 < BrainDamage> or you coule use a dedicated mcu to act as a adc
2022-10-30T18:16:49 < jpa-> *DAC, ADC part would be easily solved with the STM32 DFSDM block
2022-10-30T18:17:09 < BrainDamage> why do you insist on 2nd order sigma delta? what's the boundary on the quantization noise that you have?

2022-10-30T18:19:53 < jpa-> one can also have the quantizer output e.g. 5 bits and choose a longer sequence of output bits based on that - it changes the noise shaping frequency distribution a bit, but is a lot faster
2022-10-30T18:20:16 < jpa-> (choose output bits from lookup table)
2022-10-30T18:49:35 < Laurence_b> derp the i2s - adc mode is master only
2022-10-30T18:49:43 < Laurence_b> esp32 insists on failing
2022-10-30T18:52:06 < kaki> fpga
2022-10-30T18:56:04 < Laurence_b> the motor control pwm is nice, but without a way to sync the adc its next to useless
2022-10-30T18:56:18 < Laurence_b> I guess an isr could be used but thats getting dodgy

2022-10-30T19:10:02 < bitmask> in c++ when you have a function that has a rvalue parameter, how come to pass that to a function that accepts an rvalue parameter you have to use std::move again
2022-10-30T19:10:23 < bitmask> actually its kinda obvious
2022-10-30T19:10:27 < bitmask> i think
2022-10-30T19:10:36 < bitmask> it must turn into an lvalue inside the function

2022-10-30T19:12:11 < bitmask> what do you mean
2022-10-30T19:14:00 < bitmask> instead of passing it as a rvalue just take the rvalue of the passed lvalue?
2022-10-30T19:14:26 < bitmask> if thats what you meant, it wont work for my purpose, im overloading functions, one with lvalue one with rvalue, they behave differently
2022-10-30T19:14:36 < bitmask> so move it is
2022-10-30T19:15:40 < BrainDamage> ok, yes, if you mix l and r, it won't work
2022-10-30T19:35:20 < Laurence_b> BrainDamage: second order sigma-delta gives good performance when oversampling by a sane ratio
2022-10-30T19:35:39 < Laurence_b> I need 10 ENOB or so
2022-10-30T19:36:28 < BrainDamage> ... 10 ENOB in linear or sigma delta?
2022-10-30T19:37:17 < BrainDamage> and why can't you send 16 bits in linear over serialized pcm?
2022-10-30T19:47:02 < qyx> tbh too much overthinking, i2c or spi adc, digital isolator, consider it done
2022-10-30T19:47:16 < qyx> no point in doing sigma delta, .. or?
2022-10-30T19:51:27 < qyx> or an isolated opamp if you have $$
2022-10-30T19:51:41 < qyx> but considering you are trying to use esp32..

2022-10-30T22:31:33 < Laurence_b> they have hardware based nvic style multitasking, but the sdk uses freertos
2022-10-30T22:38:39 < Mangy_Dog> freertos can be setup to target cores
2022-10-30T22:39:14 < Mangy_Dog> not sure what nvic is though

2022-10-30T22:59:12 < Laurence_b> looks like freertos interrupt latency is only ~2us, so not so bad
2022-10-30T22:59:48 < Laurence_b> also the timers can be connected via the gpio matrix, rather like stm32 master/slave mode with signal routing
