11:37 <scorpion2185[m]> Hello for rust and PineTime what room is better? I saw this https://github.com/dbrgn/pinetime-rtic

11:43 <JamesMunns[m]> Maybe here or #rtic:matrix.org if it's specific to RTIC? If the questions are about the project in general, maybe here or the issue tracker.

11:46 <scorpion2185[m]> yes it's general. is RTIC Real Time Interface Coprocessor?

11:47 <scorpion2185[m]> it's the os name right?

11:47 <marmrt[m]> Real Time Interruptdriven Concurrency

15:42 <scorpion2185[m]> * name right? it's in my link but i did not look it in long time 😅

15:49 <scorpion2185[m]> atm is that the only active project for the pientime?

15:58 <phycrax[m]> There is one with embassy https://github.com/JoshMcguigan/mesozoic

16:09 <dirbaio[m]> there's also lulf 's https://github.com/lulf/watchful

16:09 <dirbaio[m]> his rustnl talk about it https://www.youtube.com/watch?v=u6q9l89EOXI

16:09 <dirbaio[m]> lots of people rusting the pinetime :D

16:22 <vollbrecht[m]> interesting, a couple weeks ago another kickstarter was launching with a similar watch, featuring the same processor, but also running a esp32s3. It's name was spectra. It doesn't seam there OS is open source, but they focus on "right to repair". At least physically it looks that it would be true. It seams there is a market for this stuff :D

16:23 <vollbrecht[m]> * the same nrf processor, but

16:28 <JamesMunns[m]> Turns out you can make hardware a lot cheaper when you tell the people you sell it to that software is their problem :p

16:28 <JamesMunns[m]> (this is picking more on Pine than Spectra, which I haven't seen before)

17:07 <scorpion2185[m]> >If you want to reflash your sealed PineTime to Watchful, it is possible. But there is a chance to brick your PineTime, so don't do this unless you've tried it a few times on a devkit and feel confident. Also consider the fact that once you go to Watchful, there is no way to go back at the moment.

17:08 <scorpion2185[m]> does that mean that i can brick it in a way that i cannot fix it?

17:08 <lulf[m]> Not for the faint of heart

17:09 <lulf[m]> Yes, you'd need to use a heatgun to 'unseal' it to fix it (flash it with a debug probe)

17:09 <lulf[m]> Depending on your skills, you might be able to re-seal it just fine

17:09 <scorpion2185[m]> i ordered a dev kit to mess with it

17:09 <lulf[m]> Yeah, devkit is good for experimenting

17:10 <lulf[m]> FWIW I plan to modify watchful to use trouble instead of nrf-softdevice, which will allow it to re-use the mcuboot that comes ootb with the pinetime, allowing you to try watchful without the risk

17:10 <lulf[m]> But it requires some spare time

17:11 <scorpion2185[m]> since it's already unselead i can fix it if something goes wrogn right?

17:13 <lulf[m]> Yes, it's not a problem with the devkit, where you can just use a debug probe to flash it. The above warning only applies to the sealed pinetime, where you must use a 'reloader' that allows you to 'upgrade' from infinitime to watchful without a debug probe.

17:13 <lulf[m]> For details see the above RustNL talk :P

18:19 <scorpion2185[m]> iiuc there is no simulator i watched the video but not too carefully

18:36 <scorpion2185[m]> while mesozoic simulator shows no apps almost no ui

21:17 <takkaryx[m]> Is there a recommended crc crate for no_std environments? Not sure if I’m just searching badly

21:20 <JamesMunns[m]> Theres 'crc'

21:20 <JamesMunns[m]> https://crates.io/crates/crc

21:20 <JamesMunns[m]> I think you have to turn off default features

21:21 <JamesMunns[m]> https://github.com/mrhooray/crc-rs/blob/master/src/lib.rs#L28

21:21 <JamesMunns[m]> Ah nope, always nostd

21:22 <cbjamo[m]> I've used crc several times, works great. Big fan of the pre-cooked crc constants.

21:52 <takkaryx[m]> <JamesMunns[m]> "https://github.com/mrhooray/crc..."; <- Huh, so it is, it’s not mentioned anywhere in the README and I made a poor assumption,

21:53 <takkaryx[m]> * poor assumption, thanks!
