## What it is
A collection of Rust peripheral access crates (PACs) for all STM32 microcontroller families, generated from SVD files via svd2rust with community patches. It provides a safe, type-safe API to device peripherals, one crate per STM32 family with feature-gated modules per device.

## Use cases
- write Rust firmware for an STM32F4 microcontroller
- access STM32 peripherals like GPIO, UART, and SPI from Rust
- generate safe register-level APIs from SVD files
- find a peripheral access crate for STM32H7
- start embedded Rust development on STM32 boards
- patch vendor SVD files for better register documentation

## When to choose
- you are writing bare-metal or no_std Rust firmware for any STM32 chip
- you need low-level, register-level access to STM32 peripherals
- you want community-patched, more accurate SVD-derived APIs than vendor files

## When to avoid
- you want a high-level HAL with drivers rather than raw register access
- you are targeting non-STM32 microcontrollers
- you are programming in C/C++ rather than Rust

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, programming-languages
- platform: embedded, rust
- tags: stm32, rust, pac, svd2rust, microcontroller, peripheral-access-crate, embedded-rust
