tock

6 4,960 9.9 Rust

A secure embedded operating system for microcontrollers

Project mention: OxidOS Automotive | news.ycombinator.com | 2024-03-17

Hi! This is Daniel from OxidOS Automotive (stating this for disclaimer purposes).
Yes, our OS is based on TockOS, and our CEO (Alex Radovici) is #7 in the contributors list (https://github.com/tock/tock/graphs/contributors), with other colleagues contributing in the past years.
rtic

3 1,605 8.8 Rust

Real-Time Interrupt-driven Concurrency (RTIC) framework for ARM Cortex-M microcontrollers

Project mention: Is rust used for microchip coding? | /r/rust | 2023-06-27

There's also RTIC which is another framework that makes concurrency trivial.

cortex-m

1 752 7.1 Rust

Low level access to Cortex-M processors

I do not have as strong of feelings as your parent, but:
1. A lot of the APIs make use of the typestate pattern, which is nice, but also very verbose, and might turn many people off.
2. The generated API documentation for the lower level crates relies on you knowing the feel for how it generates the various APIs. It can take some time to get used to, especially if you're used to the better documentation of the broader ecosystem.
3. A bunch of the ecosystem crates assume the "I am running one program in ring0" kind of thing, and not "I have an RTOS" sort of case. See the discussion in https://github.com/rust-embedded/cortex-m/issues/233 for example.
cortex-m-quickstart

0 712 0.0 Rust

Template to develop bare metal applications for Cortex-M microcontrollers
svd2rust

0 653 9.1 Rust

Generate Rust register maps (`struct`s) from SVD files
nrf-hal

1 466 6.8 Rust

A Rust HAL for the nRF family of devices

Project mention: Rust newcomers are 70x less likely to create vulnerabilities than C++ newcomers [pdf] | news.ycombinator.com | 2023-11-06

You should try again. I think that code is verbose because of the borrowing and because you're trying to do a one-liner. I use the nrf-hal library with the nrf52840, and the code reads pretty nicely. Here's an example:
