These crates should not be used for anything other than experimentation at this point in time, this is merely a proof-of-concept.

The esp32-hal package in this repository is NOT the same as the one published on crates.io. The published crate can be found in the esp-rs/esp32-hal repository. Once feature parity has been reached, the hope is for the version in this repository to supersede the old one.

Until the first releases are published, there should be no expectation of API stability.

Please make sure you understand all the points above, and use these packages at your own risk. When the packages in this repository are ready for general use this README will be updated to indicate such.

For additional updates, please follow along in the esp-rs channel on Matrix.

What is working?

Presently the GPIO, TIMG, and UART peripherals have drivers implemented for all supported chips. In addition the DelayUs and DelayMs traits from embedded-hal have been implemented, using the SYSTIMER peripheral for the ESP32-C3 and the internal Xtensa timers for the remaining chips.

For a complete list of which peripheral drivers are implemented for which chips, please refer to this issue.
