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.
These packages are all no_std; if you are looking for std support, please use esp-idf-svc instead.
If you have any questions, comments, or concerns, please open an issue, start a new discussion, or join us on Matrix. For additional information regarding any of the crates in this repository, please refer to the relevant crate's README.
Note
This project is still in the relatively early stages of development, and as such there should be no expectation of API stability. A significant number of peripherals currently have drivers implemented but have varying levels of functionality. For most tasks, this should be usable already, however some more advanced or uncommon features may not yet be implemented.
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.
