Coordination repository of the embedded devices Working Group (WG)
This repository issue tracker is used by the embedded WG to coordinate efforts towards making Rust a great choice for embedded development.
Want to get started with embedded development with Rust? Check out our embedded Rust book and the rest of our bookshelf.

What is it that we really want? At a broad level:
- To improve the absolute quality (functionality, safety, performance) of embedded software in the wild.
- To improve the productivity of embedded software development teams, by reducing the tangible and intangible costs of achieving a level of quality.
- To improve the experience for programmers developing for embedded systems.
- To make embedded systems programming more accessible for people that are not already embedded systems developers.
At a high level we have two main tasks:
We work with the community to improve the embedded ecosystem.
-
We maintain and develop core crates in the embedded ecosystem ensuring that the development roadmap aligns with the needs of its users. You can find all the crates we maintain in the Organization section.
-
We develop and curate resources about embedded Rust development. Check our bookshelf!
-
We maintain and moderate the venues the embedded community uses to discuss. That includes this coordination repository and our Matrix room.
And, we serve as a bridge between the Rust teams and the embedded community.
Everyone can contribute to the embedded WG efforts! There are several ways to help out:
- Let us know where the gaps are. If you think the language, the compiler, the tooling, the documentation or the crate ecosystem is lacking some feature, information or library to build embedded software let us know and we'll bring it up to the Rust teams or organize the community to build the crates or tools to fill the gaps.
- Participate in RFC (Request For Comments) threads. We are always looking into ways to improve. This may involve things from changing how we run the WG to landing major breaking changes in core crates. To ensure we are actually making things better we need your input! That's why all these changes are preceded by an "RFC", a discussion thread (which may or may not be backed by a proper RFC document) where we evaluate the pros and cons of a proposal and explore alternatives. Only after there's consensus on accepting the proposal is the proposal made effective.
- Help wanted!. There's always lots to do but the WG members only have so much free time. You can help us fixing bugs, implementing features, writing tests, trying out examples and tutorials, writing documentation, fixing typos, etc. We'll mentor you through these tasks and review your work. In some cases you may not even need previous embedded experience or access embedded hardware to help us out so don't let that discourage you from checking out our help wanted issues.
-
Join our weekly meetings on Matrix. We use these meetings as a faster, synchronous alternative to the RFC threads on GitHub. The agenda is posted in the matrix channel in advance to the meeting. Everyone is free to join the meeting and share their thoughts. You can also nominate an existing GH thread for discussion if you think it would benefit from a more synchronous discussion. The usual meeting time is Tuesdays, 8pm CET/CEST.

We have several teams focused on different areas: tooling, Cortex-M crates, etc. and each team maintains several projects (crates, docs and / or tools) that live under the rust-embedded organization. You can collaborate with the maintenance and development of these projects by becoming a project collaborator (consult with the team that owns the project) or by joining the team.
The WG is composed of several teams whose functions are defined in RFC #136. The embedded WG develops and maintains a large set of projects under the rust-embedded organization. This section lists all the teams and all the projects owned by the WG.
The functions of the core team are:
- Representing the WG in meetings with other Rust teams.
- Communicating the needs of the embedded Rust community (e.g. language features,
coreAPI stabilization) to the Rust teams. - Giving the casting vote on intra-WG decisions where no voting majority can be achieved.
- Driving and moderating the weekly meetings.
The Cortex-A team develops and maintains the core of the Cortex-A crate ecosystem.

The triage team is charge of keeping PR queues moving; they ensure no PR is left unattended.

You can usually find the members of the embedded WG on the Rust Embedded Matrix room (#rust-embedded:matrix.org).
Our Matrix room is logged by on the bridged IRC channel, and you can find the logs at: https://libera.irclog.whitequark.org/rust-embedded/
These are other projects you may be interested in but that (currently) are not owned by the WG.
Several device specific communities exist that are not part of the working group. These communities maintain crates for peripheral access, hardware abstraction, examples, and more that are specific to a particular family of devices. The list below is not exhaustive and will be updated as device support increases.
- nrf-rs: Nordic nRF series of microcontrollers
- stm32-rs: STM32 microcontrollers
- lpc-rs: NXP LPC microcontrollers
- imxrt-rs: NXP i.MX RT microcontrollers
- esp-rs: Espressif Systems microcontrollers
- rp-rs: Raspberry Pi microcontrollers including the RP2040
embedded-hal is a project that aims to build a standard set of traits (interfaces) for I/O
functionality common in embedded devices: Serial, I2C, etc. with the goal of serving as a base for
building reusable driver crates, crates to interface with external components like sensors.
There are plenty of traits that still need to be designed, in particular ones that involve async I/O. Join the discussion and help us design the missing traits so that they'll fulfill your needs.
To put the embedded-hal to test and to expand the embedded crates.io ecosystem we are running the
weekly driver initiative. The goal is to release a new no_std, generic, embedded-hal driver
crate every one or two weeks.
There's lots of cool devices that would be great to have drivers for. Join the initiative and help us grow the embedded crates.io ecosystem!
The community is building a curated list of crates useful for embedded development. In this list you'll find driver crates, board support crates and general purpose no-std crates. Help us improve this list by adding your crate via PR or by tackling any of our help wanted issues.
As an experiment the Rust lang user forum has gained a new embedded category.
This is meant as a friendly exchange for anyone interested in embedded topics with Rust.
So if you want to discuss ideas, problems or solutions please feel free to chime in on existing topics or create a new one!
When the team deems it necessary the RFC process may be used to make decisions or to design processes, user interfaces, APIs, etc.
Learn more about the Rust's RFC process (which is the same as our own) here.
To create an RFC, simply:
- clone this repo to your own personal one
- copy
0000-template.mdtotext/0000-my-feature.md(where "my-feature" is descriptive. Don't assign an RFC number yet) - fill in the details of your RFC in that file
