## What it is
rp-hal is a Rust Hardware Abstraction Layer (HAL) implementing embedded-hal for the Raspberry Pi RP2040 and RP235x series microcontrollers. It provides high-level drivers and board support packages for programming Raspberry Pi Pico boards in Rust.

## Use cases
- write Rust firmware for Raspberry Pi Pico
- program RP2040 microcontroller in Rust
- blink LEDs and read GPIO on RP235x
- use PIO state machines on Pico
- build embedded Rust projects with embedded-hal traits
- flash UF2 images to Pico 2 via USB bootloader

## When to choose
- you want to develop Rust applications for RP2040 or RP235x microcontrollers
- you need a safe, high-level API over Raspberry Pi Pico hardware
- you want embedded-hal compatible drivers for Pico boards

## When to avoid
- you are programming a Raspberry Pi single-board computer (Linux) rather than the microcontrollers
- you need C/C++ SDK support or MicroPython instead of Rust
- your target microcontroller is not from the RP series

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, rust
- tags: raspberry-pi, rp2040, rp235x, embedded-hal, microcontroller, pico, no-std, bsp
