Crate stm32_metapac

Expand description

You might want to browse the `embassy-nrf` documentation on the Embassy website instead.

The documentation here on `docs.rs` is built for a single chip only (stm32h755zi-cm7 in particular), while on the Embassy website you can pick your exact chip from the top menu. Available peripherals and their APIs change depending on the chip.

§stm32-metapac

This is a Peripheral Access Crate for STMicroelectronics STM32 microcontrollers.

This crate has been automatically generated based on data in the stm32-data project, and is used for the embassy-stm32 Rust Hardware Abstraction Layer (HAL) for the STM32 microcontrollers.

§Metadata

This PAC additionally exports “metadata” about the chips. To use it, enable the metadata feature and access it at stm32_metapac::METADATA. It is intended to be consumed from build.rs scripts or code-generation tools running on PCs, not from the firmware itself.

The metadata includes the following info:

Memory maps for RAM, flash.
Interrupts
GPIO Alternate Function mappings
Interrupt -> peripheral mappings
DMA channel -> peripehral mappings
RCC clock tree information for each peripheral (what clocks does it receive, which RCC registers to poke to enable, reset, or choose the clock)

§Supported chips

This PAC aims to support all STM32 chip families:

STM32F0
STM32F1
STM32F2
STM32F3
STM32F4
STM32F7
STM32C0
STM32G0
