## What it is
RPPAL is a Rust library providing access to the Raspberry Pi's GPIO, I2C, PWM, SPI, and UART peripherals through a user-friendly interface, with embedded-hal trait implementations. It was retired by its maintainer on July 1, 2025 and no longer receives updates, bug fixes, or support.

## Use cases
- control GPIO pins on a Raspberry Pi from Rust
- read sensors over I2C on Raspberry Pi
- drive SPI devices like displays or ADCs from Rust
- generate PWM signals for servos or motors
- communicate over UART serial on Raspberry Pi
- use embedded-hal drivers with Raspberry Pi hardware

## When to choose
- you need Rust peripheral access on a Raspberry Pi model released before July 2025
- you want embedded-hal compatible drivers on Raspberry Pi
- you're okay using an unmaintained but stable library

## When to avoid
- you need support for Raspberry Pi hardware released after July 2025
- you require ongoing bug fixes or active maintenance
- you're starting a new long-term project and want a maintained alternative

## Facets
- artifact type: library
- maturity: abandoned
- function: embedded, sdk
- domain: embedded-systems, hardware, developer-tools
- platform: rust
- tags: raspberry-pi, gpio, i2c, spi, uart, pwm, embedded-hal, retired, linux
