esp-lp-hal
no_std HAL for the low-power RISC-V coprocessors found on the ESP32-C6, ESP32-S2, and ESP32-S3 from Espressif.
Implements a number of the traits defined in embedded-hal.
These devices uses the RISC-V ISA, which is officially supported by the Rust compiler via the riscv32imc-unknown-none-elf and riscv32imac-unknown-none-elf targets.
Please refer to the documentation for more information.
