esp32s3-hal
no_std HAL for the ESP32-S3 from Espressif. Implements a number of the traits defined by embedded-hal.
This device uses the Xtensa ISA, which is not officially supported by the Rust compiler. In order to develop for this device you must use the Rust compiler fork with Xtensa support found at esp-rs/rust. Refer to the Getting Stared section below for more information.
