Rust on Espressif microcontrollers

This organization is home to several projects enabling the use of theRust programming language on various SoCs and modules produced byEspressif Systems.

If you are just getting started writing Rust for ESP devices, please first readThe Rust on ESP book.

For a curated list of resources for development including tools and projects, seeAwesome ESP Rust.

Hardware Abstraction Layer

We offer two choices forHardwareAbstractionLayers:

Repository	Description	Support status
esp-rs/esp-hal	Without support for the Rust standard library (`no_std`)
esp-rs/esp-idf-hal	With support for the Rust standard library (`std`)

Build Tools

This organization contains a fork of the Rust compiler with added support for the Xtensa ISA. Pre-built binaries for said compiler fork are additionally provided for most common operating systems and architectures.

Repository	Description
esp-rs/rust	Rust compiler fork with Xtensa support
esp-rs/rust-build	Pre-built binaries of the Rust compiler fork, plus installation scripts
