11:41 <re_irc> < (@chrysn:matrix.org)> nRF users, how do you usually set your UICR values, especially when using a debugger (eg. nrf52dk's build in one) that regularly requires you to "nrf-recover"?

11:43 <re_irc> < (@chrysn:matrix.org)> I currently have a hand-crafted .hex file that I let srec_cat wiggle into the release file, and manually set the UICR values in software at startup (where a nicer way might be to take the same hex file and flash it the same way I flash the softdevice before flashing the actual software), but that's all not really pretty, but I'd probably re-invent the wheel if I tried to be smart.

11:58 <re_irc> <Stephen D> I'm having a great deal of trouble getting my ADC to start conversion when a timer fires. My ADC is set up with "external_trigger(TriggerMode::RisingEdge, ExternalTrigger::Tim_1_cc_1)" but I'm not sure how to configure the timer to fire that. I also tried "ExternalTrigger::Tim_2_trgo" (with tim2 configured normally, the way I would if I wanted to trigger a TIM2 interrupt) but it also didn't trigger the ADC

12:58 <explore> hi

13:00 <explore> is there something spirtually akin to "ruby on rails"/"convention over configuration" helping to save web dev's time---but for robotics or embedded systems?

13:00 <explore> it doesn't have to be Rust, any popular embedded/real-time/robotics I don't know...

13:00 <explore> like convention-over-configuration for the most common type of robotics programming?

13:01 <re_irc> < (@k900:0upti.me)> What's the "most common type of robotics programming"?

13:03 <explore> I heard an attempt was made at such a thing, using Elixir/Erlang

13:04 <explore> there was an old presentation, 5 years ago, https://www.youtube.com/watch?v=zBzKoV2iFdQ

13:04 <re_irc> < (@k900:0upti.me)> But what does "most common type of robotics programming" even mean

13:04 <re_irc> < (@epbuennig:matrix.org)> a framework that works out of the box?

13:04 <re_irc> < (@k900:0upti.me)> Like, a framework for _what_

13:04 <re_irc> < (@epbuennig:matrix.org)> since they mention ruby on rails

13:05 <re_irc> < (@epbuennig:matrix.org)> and convention over config

13:05 <re_irc> < (@k900:0upti.me)> "Robotics" is way more vague than backend web dev

13:05 <re_irc> < (@k900:0upti.me)> And Rails is not exactly a good fit for _every_ backend application either

13:05 <re_irc> <John Richard > This is the best time to get involved especially if you’re new to crypto. But don't just join and start purchasing cheap cryptocurrencies at random. Go in for serious crypto education instead so that you’ll be well equipped before the next bull run. If you want to make money without learning something that’s gambling (no pain - no gain).

13:05 <re_irc> https://matrix.to/#/#wealth_sensei:matrix.org

13:05 <re_irc> <Stephen D> explore: Rust has RTIC which is a framework. Not sure if it's a framework that will fit whatever usecase you have in mind

13:07 <re_irc> < (@epbuennig:matrix.org)> John Richard : fuck off

13:07 <re_irc> < (@k900:0upti.me)> That's a spambot

13:07 <re_irc> < (@k900:0upti.me)> Don't bother engaing

13:07 <re_irc> < (@k900:0upti.me)> * engaging

13:08 <re_irc> <Dlaw> : I am new to Rust (lurking in this channel as I work through the embedded Rust learning curve) but have some background in robotics. I don't totally understand what you are asking for but https://www.ros.org/ is standard in many parts of the industry as a "general framework" for running big complicated robots.

13:09 <re_irc> <Dlaw> It's not really equivalent to embedded Rust though. It's more like a glue that would tie together a bunch of different embedded systems.

13:09 <re_irc> < (@epbuennig:matrix.org)> Oh I wasn't asking, you probably meant explore

13:10 <explore> Stephen: thank you, i will check it out

13:10 <re_irc> <Dlaw> whoops, yes

13:10 <explore> Dlaw: thanks will check it out too

13:11 <re_irc> < (@k900:0upti.me)> explore: you should really explain what you're actually looking to _do_

13:11 <explore> what the hell is your problem k900?

13:11 <re_irc> < (@k900:0upti.me)> Uhh, none?

13:11 <explore> just leave it already

13:11 <re_irc> < (@k900:0upti.me)> Just trying to help

13:12 <re_irc> <Dlaw> explore: to be fair, I work in robotics and I also don't really understand what type of system you are asking about. The analogy with ruby on rails is confusing to me.

13:12 <re_irc> < (@k900:0upti.me)> If you just want something that has the word "framework" in the name, maybe look into https://embassy.dev/ too

13:12 <re_irc> < (@k900:0upti.me)> But there's way too many things you could be looking to do here, and no "framework" will be a one-size-fits-all solution

13:13 <re_irc> < (@k900:0upti.me)> Which is why I'm asking the initial question

13:14 <re_irc> < (@k900:0upti.me)> "Robotics" is a much bigger problem space than "CRUD web apps", so if you can narrow down your requirements, it will be easier to recommend something that fits them

13:18 <re_irc> <Stephen D> explore: You are providing minimal explanation of what you want to do and making it our job to force that information out of you. Nobody here is paid, they're all volunteers

13:18 <re_irc> < (@jamesmunns:beeper.com)> Reminder: please don't interact with spammers, just report it or ping one of the admin/mods

13:19 <explore> i shared a 45 minute talk intended for luddites that explains everything, scroll up for youtube link

13:20 <re_irc> < (@jamesmunns:beeper.com)> Also - reminder to please be kind/respectful to each other

13:20 <explore> must i regurgitate the talk in my own words?

13:20 <re_irc> < (@k900:0upti.me)> Oh cool, so we're also luddites now

13:20 <explore> no, i am the luddite

13:20 <explore> you are the toxic whatever

13:20 <re_irc> < (@k900:0upti.me)> Also, I'm sorry if this comes off as harsh, but no one here is watching a 45 minute talk to figure out what you're asking about

13:20 <re_irc> < (@k900:0upti.me)> OK, I'm done here

13:21 <re_irc> < (@jamesmunns:beeper.com)> Hey and explore, please cool it for a bit.

13:21 <re_irc> < (@jamesmunns:beeper.com)> explore - you're more likely to get good answers if you explain what you are looking for - not everyone can/will want to watch a video, so any text summary you can provide will help.

13:21 <explore> i asked an innocent enough question, and someone made it overly dramatic and egotistical and i can't put out the fire

13:22 <explore> and i am not paid to be a fire fighter, so i'll go away and read up

13:22 <explore> action over drama

13:22 <re_irc> <Stephen D> explore: Are you expecting people here to spend 45 minutes watching a video just so they can provide you with free help?

13:23 <re_irc> <Stephen D> @irc_libera_explore:psion.agg.io: They were being perfectly respectful

13:23 <re_irc> < (@k900:0upti.me)> ¯\_(ツ)_/¯

13:25 <re_irc> < (@jamesmunns:beeper.com)> I agree - I don't think 's requests for more information were disrepectful, and without watching the video, I'm also not sure what you are asking for, other than Dlaw's suggestion to look into ROS/ROS2

13:25 <re_irc> < (@k900:0upti.me)> They're gone btw

13:25 <re_irc> < (@jamesmunns:beeper.com)> Fair.

13:26 <re_irc> < (@jamesmunns:beeper.com)> In general y'all (I'm sure I'm preaching to the choir here): please assume good intent from others, and feel free to remind people to follow that policy.

13:29 <re_irc> <Dlaw> Since k900 mentioned embassy... anyone have any thoughts to share on embassy vs RTIC? I just finished my first "feet wet" project with RTIC (a little RFID reader, about 200 lines of code), and now need to decide whether to stick with RTIC or try something else for a STM32 motor control project. I expect a lot of of low level interaction with timer peripherals in unusual PWM and encoder modes which may not be supported by...

13:29 <re_irc> ... the HALs.

13:31 <re_irc> < (@jamesmunns:beeper.com)> I wrote a thing up on this a while back: https://cohost.org/jamesmunns/post/67555-should-i-use-embassy

13:32 <re_irc> <Dlaw> Oh, my, thank you! I did search around for "embassy vs RTIC" but somehow never found this writeup which exactly answers my question.

13:32 <re_irc> < (@jamesmunns:beeper.com)> I don't think cohost is well indexed by google (and/or DDG) yet :/

14:24 <re_irc> < (@lulf_:matrix.org)> You can also mix embassy and RTIC, using embassy HALs (it has both blocking and async implementations) with RTIC for instance (which also I think can do async tasks now).

14:31 <explore> howzit going?

14:33 <re_irc> < (@jamesmunns:beeper.com)> if you left and returned explore, you might want to look at the logs, specifically about chat expectations here: https://libera.irclog.whitequark.org/rust-embedded/2022-11-28#1669641918-1669645871;

14:38 <explore> none of the people i talked to here "here" so you are talking about chat expectations elsewhere

14:39 <re_irc> < (@jamesmunns:beeper.com)> No? I'm talking about the expectations in this room, specifically: assuming that people are here with good intent.

14:39 <explore> so would you like me to write some lore about libera so you guys can learn how not to be super toxic and put words in other people's mouth and then turn around and time out that very very bewildered person?

14:40 <explore> no, you are in some other network, you are not here

14:40 <re_irc> <Stephen D> explore: You are being toxic, no offense

14:40 <explore> there's an irc bot that relays

14:40 <re_irc> < (@jamesmunns:beeper.com)> We are on matrix, which is bridged to libera (as a courtesy), with matrix as the authoritative chat.

14:41 <explore> right, a superior network with superior minds letting us mere mortals listen in?

14:41 <re_irc> < (@jamesmunns:beeper.com)> I've banned the user.

14:41 <re_irc> < (@jamesmunns:beeper.com)> CC , does heisenbridge handle IRC bans correctly?

14:50 <re_irc> < (@jamesmunns:beeper.com)> Also, as a general reminder (which is in the header of both the matrix and libera matrix chat), these rooms work under the Rust code of conduct: https://www.rust-lang.org/policies/code-of-conduct, if you have moderation questions, please feel free to mention or DM any of the admins/mods here, or if you feel that we aren't doing a reasonable job, feel free to reach out to the Rust Moderation team:...

15:08 <re_irc> < (@adamgreig:matrix.org)> Heisenbridge won't automatically reflect a matrix ban onto irc as it doesn't have ops on the irc side, but the ban does apply on the matrix side (naturally)

15:12 <re_irc> < (@jamesmunns:beeper.com)> Thanks!

15:34 <re_irc> <balint133> Hi all, I'm considering porting an embedded C++ application to Rust but I've hit a small barrier. The application currently supports over 100 different boards with the same MCU/architecture but with different pin layout and peripherals attached. For this, I have a good chunk of code that's doing runtime configuration based on configuration files. I have a very hard time figuring out how to do something similar with...

15:34 <re_irc> ... embedded Rust. Do I have to write my own HAL or is there a way to do runtime configuration with the existing HAL libraries or maybe do something clever with Cargo?

15:57 <re_irc> <rjmp> balint133: perhaps if you share more specifically whats giving you a hard time people can help more directly. In general, I think heavy typestate use makes what your trying to do hard, e.g. many hal peripherals include the configured pins in their type, which is now part of allocating storage for peripheral.

15:57 <re_irc> Ive seen this HAL, which might be a bit more friendly to your situation (https://github.com/David-OConnor/stm32-hal)

15:59 <re_irc> <rjmp> It has GPIOs with mem state (i.e. fields in mem with peripheral and pin number) which makes run time config of gpios easy

15:59 <re_irc> <balint133> Thanks, I'll check this out. You're correct what'

15:59 <re_irc> <balint133> * what's giving me the most trouble is the heavy reliance of typestates. Makes runtime config difficult or outright impossible

16:07 <re_irc> <rjmp> One possible approach could be to do a one time heap allocation if your "system", and the your main application would acces everything via traits.

16:08 <re_irc> <rjmp> * of

16:32 <re_irc> <Stephen D> Sorry for the bump, I think this got overshadowed by the other guy who got banned

19:37 <re_irc> <brxken128> is "embedded-text" completely broken? this is supposed to say "1Player" but does not

19:37 <re_irc> <brxken128> https://psion.agg.io/_matrix/media/r0/download/matrix.org/ftHkSTvoZZcTzZafZPVmgxJz/image.png

19:37 <re_irc> <brxken128> lemme put relevant code into a gist

19:39 <re_irc> <brxken128> https://gist.github.com/brxken128/134683b2488f03803dc883c60891eec3 the "st7789_pico1" has internal offsets to make the display size correctly and allow for everything to show, but text will _not_ show past a certain point, even if i make the text box absurdly large

19:40 <re_irc> <brxken128> i've tried messing around with the start point, size, etc. the bounds of the text box display to the full correct size (when the rectangle is drawn with a red stroke), just the text refuses to show correctly

19:43 <re_irc> <brxken128> +height modes, alignments,

19:45 <re_irc> <brxken128> https://gist.github.com/brxken128/134683b2488f03803dc883c60891eec3 the "st7789_pico1" has internal offsets to make the display size correctly and allow for everything to show, but text will _not_ show past a certain point, even if i make the text box absurdly large

19:45 <re_irc> (this is with "mipidsi", "embedded-text" and an esp32-s3)

21:38 <re_irc> < (@9names:matrix.org)> it can be a bit misleading, lines can draw out of bounds but filled primitives will not. try drawing a filled rectangle and see if it gets cut off as well.

21:38 <re_irc> it's most likely that the bounds/offsets in st7789_pico1 are not correct for your screen.

21:53 <re_irc> < (@9names:matrix.org)> Stephen D: not just that. you haven't provided any context - i don't know which mcu you're targeting so I don't know if i _can_ help you.

21:53 <re_irc> eventually someone is going to ask these sort of questions and help you out, but it's more efficient if you can provide as much info as you have to begin with so we know where to start.

21:55 <re_irc> <brxken128> : the filled rectangle fills the screen correctly, which is what's puzzling me so much

21:55 <re_irc> <brxken128> i'll take a photo and show you

21:58 <re_irc> <Stephen D> : You're right, my bad. I'm targetting an stm32f411. My code is here: https://gitlab.scd31.com/stephen/stm32-pager

21:58 <re_irc> <brxken128> https://psion.agg.io/_matrix/media/r0/download/matrix.org/UVKYAlAUvjCTHntdLpJGjwxL/image.png

21:58 <re_irc> <brxken128> terrible photo, i apologise, but that is with the exact same "bounds" rectangle

21:58 <re_irc> <brxken128> just with a red fill colour

21:59 <re_irc> <brxken128> but the text just cuts off, as if it's using the "st7789" display model in "mipidsi" with no offset

22:00 <re_irc> <brxken128> (it's probably not, although that's the closest comparison i have for it)

22:02 <re_irc> <brxken128> +also the first picture was one of my attempts with a super wide text box, which is why it's not perfectly centered

22:05 <re_irc> <brxken128> +it's the adafruit esp32-s3 tft feather, the SKU for the display is " ADA4383" if that helps (240x135, st7789, seems to have an offset pretty identical to the pico1 mipidsi model from my testing with a filled box and contrasting outline)

22:15 <re_irc> < (@9names:matrix.org)> brxken128: i don't have a project using a recent mipidsi to test your code with rp2040 to verify quickly, will test it out later.

22:16 <re_irc> as you say, the screen should have the same offsets so it's weird that it's not working. might be worth creating an issue on mipidsi github to keep track of this.

22:17 <re_irc> <brxken128> : i think that'll have to be the plan, i'll go ahead and make one. it could just be user error, but i've tried pretty much everything i can at this point haha

22:20 <re_irc> < (@9names:matrix.org)> just so we're clear: in real life that rectangle is filled red yeah? it's just the photo that looks white?

22:22 <re_irc> <brxken128> oh yes i apologise, it's fully red

22:49 <re_irc> < (@9names:matrix.org)> Stephen D: i think you're using the timer in a counter mode in the code you linked, which is not using capture-compare, so that trigger would never fire. you might be able to get this interrupt to trigger if you set the timer in PWM mode since that would use CC. it's also possible you'll need to configure the timer peripheral manually by setting registers using the PAC based on the C SDK examples.

22:51 <re_irc> < (@9names:matrix.org)> the programmers manual for the chip should also outline how to do this

22:56 <re_irc> <Stephen D> : Thanks. I did try PWM mode but it didn't work either. I'm going to try setting up CC manually

22:56 <re_irc> <Stephen D> And who knows, maybe I'll even open a PR to add some logic around configuring CC without messing with registers
