README
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)

This PAC aims to support all STM32 chip families:
- STM32F0
