Crate esp32c6_hal

no_std HAL for the ESP32-C6 from Espressif.

Implements a number of the traits defined by the various packages in the embedded-hal repository.

Cargo Features

• async - Enable support for asynchronous operation, with interfaces provided by embedded-hal-async and embedded-io-async
• debug - Enable debug features in the HAL (used for development)
• defmt - Enable defmt::Format on certain types
• direct-boot - Use the direct boot image format
• direct-vectoring - Enable direct vector table hooking support
• eh1 - Implement the traits defined in the 1.0.0-xxx pre-releases of embedded-hal, embedded-hal-nb, and embedded-io
• embassy - Enable support for embassy, a modern asynchronous embedded framework. One of embassy-time-* features must also be enabled when using this feature.
• embassy-time-systick - Enable the embassy time driver using the SYSTIMER peripheral
• embassy-time-timg0 - Enable the embassy time driver using the TIMG0 peripheral
• interrupt-preemption - Enable priority-based interrupt preemption
• log - enable log output using the log crate
• rt - Runtime support
• ufmt - Implement the ufmt_write::uWrite trait for the UART and USB Serial JTAG drivers
• vectored - Enable interrupt vectoring

Default Features

The rt and vectored features are enabled by default.

Supported Image Formats

This HAL supports building multiple different application image formats. You can read about each below.

The ESP-IDF Bootloader format is used unless some other format is specified via its feature.

ESP-IDF Bootloader

Use the second-stage bootloader from ESP-IDF and its associated application image format. See the App Image Format documentation for more information about this format.

Direct Boot

This device additionally supports direct-boot, which allows an application to be executed directly from flash, without using the second-stage bootloader. For more information please see the esp32c3-direct-boot-example in the Espressif organization on GitHub.
