esp-hal
Bare-metal (no_std) hardware abstraction layer for Espressif devices. Currently supports, to varying degrees, the following devices:
- ESP32 Series: ESP32
- ESP32-C Series: ESP32-C2, ESP32-C3, ESP32-C6
- ESP32-H Series: ESP32-H2
- ESP32-S Series: ESP32-S2, ESP32-S3
Additionally provides limited support for programming the low-power RISC-V cores found on the ESP32-C6, ESP32-S2, and ESP32-S3 via the esp-lp-hal package.
For additional information regarding any of the crates in this repository, please refer to the relevant crate's README.md file. If you have any questions, comments, or concerns, please open an issue, start a new discussion, or join us on Matrix.
If you are currently using (or considering using) esp-hal in a production environment and have any feedback or require support, please feel free to contact us at rust.support@espressif.com.
Note
This repository includes crates that are at various stages of maturity and stability. While many functionalities have already been implemented and are usable for most tasks, certain advanced or less common features may still be under development. Each crate may offer different levels of functionality and guarantees.
Getting Started
For information relating to the development of Rust applications on ESP devices, please first read The Rust on ESP Book.
For information about the HAL and how to use it in your own projects, please refer to the documentation.
When browsing the examples, we recommend viewing the tag for the esp-hal release you are using to ensure compatibility, e.g. esp-hal-v1.0.0-beta.0, as the main branch is used for development and APIs may have changed in the meantime.
