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
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-asyncdebug
- Enable debug features in the HAL (used for development)defmt
- Enabledefmt::Format
on certain typesdirect-vectoring
- Enable direct vector table hooking supporteh1
- Implement the traits defined in the1.0.0-xxx
pre-releases of embedded-hal, embedded-hal-nb, and embedded-ioembassy
- Enable support for embassy, a modern asynchronous embedded framework. One ofembassy-time-*
features must also be enabled when using this feature.embassy-time-systick
- Enable the embassy time driver using theSYSTIMER
peripheral. TheSYSTIMER
peripheral has three alarms available for useembassy-time-timg0
- Enable the embassy time driver using theTIMG0
peripheral. TheTIMG0
peripheral has a single alarm available for useembassy-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 driverembassy-generic-queue-N
(whereN
can be8
,16
,32
,64
or128
) - Use a generic timer queue of sizeN
for the executors’ timer queues. Using this feature can expand the number of executors you can use toN
interrupt-preemption
- Enable priority-based interrupt preemptionlog
- enable log output using thelog
cratert
- Runtime supportufmt
- Implement theufmt_write::uWrite
trait for the UART and USB Serial JTAG driversvectored
- Enable interrupt vectoringflip-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.
