Crate esp32h2_hal

Source
Expand description

no_std HAL for the ESP32-H2 from Espressif.

This package has been deprecated in favour of esp-hal. Please refer to the migration guide for help with updating your projects to use the new esp-hal package:

https://github.com/esp-rs/esp-hal/releases/tag/v0.16.0

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-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. The SYSTIMER peripheral has three alarms available for use
  • embassy-time-timg0 - Enable the embassy time driver using the TIMG0 peripheral. The TIMG0 peripheral has a single alarm available for use
  • embassy-integrated-timers - Uses hardware timers as alarms for the executors. Using this feature limits the number of executors to the number of hardware alarms provided by the time driver
  • embassy-generic-queue-N (where N can be 8, 16, 32, 64 or 128) - Use a generic timer queue of size N for the executors’ timer queues. Using this feature can expand the number of executors you can use to N
  • 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
  • flip-link - move the stack to the start of RAM to get zero-cost stack overflow protection
§Default Features

The rt, vectored and embassy-integrated-timers features are enabled by default.
