## What it is
SwiftyGPIO is a Swift library for hardware projects on Linux/ARM single-board computers like the Raspberry Pi, BeagleBone, and Orange Pi. It provides interfaces for GPIOs, SPI, I2C, PWM, UART serial, and 1-Wire buses to control sensors, displays, LEDs, and other external devices.

## Use cases
- blink an LED from Swift on a Raspberry Pi
- read sensor data over I2C with Swift
- drive servos or LEDs using PWM on ARM boards
- communicate with devices over UART serial
- control NeoPixel or RGB LED strips via SPI
- read 1-Wire temperature sensors on Linux SBCs

## When to choose
- you want to write embedded hardware code in Swift on Linux ARM boards
- you need GPIO/SPI/I2C/PWM/UART access on a Raspberry Pi or similar SBC
- you prefer Swift over Python for DIY hardware projects

## When to avoid
- you target microcontrollers like Arduino or ESP32 rather than Linux SBCs
- your project runs on macOS or Windows, since the library is Linux-only
- you need a mature ecosystem with extensive community support

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools
- domain: iot, embedded-systems, hardware
- platform: embedded, iot
- tags: gpio, spi, i2c, pwm, uart, 1-wire, raspberry-pi, single-board-computers, sensors, led-strips, neopixel, hardware-interfaces, linux, swift
