00:14 <re_irc> <@shakencodes:matrix.org> Agreed on working with RTIC and/or Embassy. I've got decent experience on RTIC and even sponsored development of an active object layer for it. -- I'm in the act of wiring up SemTech's LoRaWAN infrastructure (all C code) to a Rust application, as the existing Rust LoRa infrastructure doesn't support Class C or Multicast messaging (yet).

00:14 <re_irc> All the other stuff in the application is Rust and I built right on top of the HAL and has worked swimmingly.

00:51 <re_irc> <@dngrs:matrix.org> oh nice!

02:28 <re_irc> <@jamesmunns:beeper.com> : Notably, the PAC will have an enum called "Interrupt" that holds the name of all the interrupts as variants

02:29 <re_irc> <@dngrs:matrix.org> TIL that's a standard convention, nice

02:38 <re_irc> <@jamesmunns:beeper.com> Well, it's what svd2rust generates

02:38 <re_irc> <@jamesmunns:beeper.com> It's somewhat convention that hals re-export it (or the PAC as well)

10:12 <re_irc> <@thejpster:matrix.org> I saw today that the HiFive crate is a) linked from the SiFive website, and b) owned by the Rust Embedded RISC-V team: https://docs.rs/crate/hifive1/latest

10:13 <re_irc> <@thejpster:matrix.org> It may be worth thinking about moving that out to a seperate device-specific group (like nrf-rs, stm-rs, rp-rs, etc) rather than having it in the RISC-V team. The other Rust Embedded teams have tried quite hard to be device-agnostic and stick to only architecture-level software.

10:13 <re_irc> <@thejpster:matrix.org> But also very cool that SiFive link to it.

10:14 <re_irc> <@thejpster:matrix.org> (here: https://www.sifive.com/boards/hifive1-rev-b)

11:53 <re_irc> <@dkhayes117:matrix.org> I don't think it's apart of the riscv wg. It's under riscv-rust which isn't under the wg.

12:30 <re_irc> <@9names:matrix.org> what is riscv-rust?

12:33 <re_irc> <@9names:matrix.org> https://psion.agg.io/_matrix/media/r0/download/matrix.org/MWYwdzSrmKJclaOVjceikBKP/image.png

12:33 <re_irc> <@9names:matrix.org> cool logo

12:39 <re_irc> <@dkhayes117:matrix.org> It's just a group where we work on riscv stuff without it being bound to the working group. I think David craven started it, maybe disasm?

12:42 <re_irc> <@bugadani:matrix.org> I'm confused, the crate's copyright points at https://github.com/rust-embedded/wg#the-risc-v-team as the copyright holder

12:44 <re_irc> <@9names:matrix.org> e310x-hal even says that "This project is developed and maintained by the RISC-V team." linking to the above ^

12:47 <re_irc> <@9names:matrix.org> do the teams on that page mean anything these days?

12:47 <re_irc> are the people listed part of the wg?

12:48 <re_irc> <@9names:matrix.org> the only person on the triage team doesn't appear to have been active for a very long time

12:57 <re_irc> <@thejpster:matrix.org> The rust-embedded/wg page should be a copy of the official list at https://github.com/rust-lang/team/tree/master/teams.

13:12 <re_irc> <@dkhayes117:matrix.org> : Maybe a copy paste thing? Idk, I remember asking disasm a long time ago about making these repos apart of the wg, but he didn't want to. Partly because you need a reviewer before anything can be merged.

13:20 <re_irc> <@9names:matrix.org> makes sense, you definitely don't want to pile more work on the WG folks

13:26 <re_irc> <@9names:matrix.org> i assume you're a member of riscv-rust? the people publicly listed on the team page are danc86, dvc94ch, and Disasm.

13:31 <re_irc> <@dkhayes117:matrix.org> Yes, I think I am.

13:31 <re_irc> <@dkhayes117:matrix.org> It's been a while since I've had time to work on rv stuff

13:34 <re_irc> <@9names:matrix.org> i know that feeling 😪

15:00 <re_irc> <@thejpster:matrix.org> but also because these are SiFive specific and the WG stuff is device-agnostic.

15:39 <re_irc> <@almindor:matrix.org> I think this is mostly some historic logistical baggage. Riscv-rust owns the e310 and k210 etc. We should def. Clear things up while also bringing up ci and pr rules to parity with the wg stuff.

16:09 <re_irc> <@dirbaio:matrix.org> I remember a while ago someone posted a project that could generate the "memory.x" file for any STM32 chip. It had a ton of "if"s that could decode the right flash/ram size based on the letters in the stm32 chip number. I'm incapable of finding it. Does anyone have a link to it?

16:30 <re_irc> <@lambdafriend:matrix.org> 👋I'm back!

16:30 <re_irc> I've been plugging away at implementing ADC reads of multiple channels using DMA and a circular buffer. The main use-case is being able to read the DMA buffer from any context, not just inside an interrupt. I've opened a draft PR (https://github.com/stm32-rs/stm32h7xx-hal/pull/442) over in the "stm32h7xx-hal" so if anyone feels like ripping apart a PR and some terrible code... well... here you go 😄

16:30 <re_irc> I'm not entirely sure if the use-case is even possible in a safe manner, but I'm relatively new to embedded.

16:30 <re_irc> <@lambdafriend:matrix.org> * 👋 I'm

19:59 <re_irc> <@ragarnoy:matrix.org> hey, odd question beginner question, I bought a RAK4631 which has a NRF52840 MCU, so I'm using the NRF52840 HAL but when using the pins labeled for the LED on the RAK4631/RAK19007 (the base) it doesn't do anything, it turns out to be the P1_03 but this information isn't anywhere, how do I find the correct datasheet/pins for what I'm trying to do ?

20:00 <re_irc> this example seem to have the correct pins https://github.com/embassy-rs/embassy/blob/main/examples/nrf52840/src/bin/lora_cad.rs but otherwise I have no idea how this person found out which pin did what

20:38 <re_irc> <@datdenkikniet:matrix.org> The schematic diagram (https://docs.rakwireless.com/Product-Categories/WisBlock/RAK4631/Datasheet/#schematic-diagram) on the product page for that product seems to mention it (there are 2 pins labeled "LED{1,2}" on the right side of the RAK4630 module)

20:38 <re_irc> <@datdenkikniet:matrix.org> * module seems to mention it (there are 2 pins labeled "LED{1,2}" on the right side of the RAK4630 module) with the correct pins assigned.

20:58 <re_irc> <@ragarnoy:matrix.org> : oh i didn't think the info would be there, thanks a lot
