Crate hal

Provides MCU-specific items.

This module dispatches between one of the following crate, depending on the target MCU family:

Manufacturer	MCU family	Docs rendered for	Items imported
Espressif	ESP32	ESP32-C6	ariel-os-esp::*
Nordic Semiconductor	nRF	nRF52840	ariel-os-nrf::*
Raspberry Pi	RP	RP2040	ariel-os-rp::*
STMicroelectronics	STM32	STM32W55RGVX	ariel-os-stm32::*

Documentation is only rendered for the MCUs listed in the table above, but many others are supported. To render the docs locally for the MCU of your choice, adapt the cargo doc command used to generate documentation for the relevant crate.

Portability

To ensure portability of your application, it is recommended to use the generic, MCU-family-agnostic items provided in other modules. Items from this module should only be used when MCU-specific settings are necessary for your application.

Macros

• define_peripherals
  This macro allows to obtain peripherals from the one listed in the peripherals module exported by this crate.
• group_peripherals
  This macro allows to group peripheral structs defined with define_peripherals! into a single peripheral struct.
