stm32h5xx-hal

stm32h5xx-hal contains a hardware abstraction layer on top of the peripheral access API for the STMicro STM32H5xx family of microcontrollers. The idea behind this crate is to gloss over the slight differences in the various peripherals available on those MCUs so a HAL can be written for all chips in that same family without having to cut and paste crates for every single model.

Supported MCUs

The following STM32H5xx MCUs are supported by the HAL:

Part	RM	Dev board
stm32h503	RM0492 ^(errata)	Nucleo H503RB
stm32h523	RM0481 ^(errata)
stm32h533	RM0481 ^(errata)	Nucleo H533RE
stm32h562	RM0481 ^(errata)
stm32h563	RM0481 ^(errata)	Nucleo H563ZI
stm32h573	RM0481 ^(errata)

Peripheral Support

For all listed MCUs above, core clock & power configuration and startup is implemented. The status of support for peripherals is shown in the table below.

Peripheral/Feature	Supported?	Issue	Notes

Minimum supported Rust version

The Minimum Supported Rust Version (MSRV) at the moment is 1.78.0. Older versions may compile, especially when some features are not used in your application.

Getting Started

The examples folder contains several example programs. To compile them, specify the target device in a cargo feature:

$ cargo build --features=stm32h523,rt --example <example>

If you are unfamiliar with embedded development using Rust, there are a number of fantastic resources available to help.
