## What it is
A pure-Go library for accessing GPIO pins on Raspberry Pi boards without external C dependencies like WiringPI or bcm2835. It supports pin input/output, pull-up/down, PWM, clock modes, edge detection, and SPI communication via /dev/gpiomem.

## Use cases
- control GPIO pins on a Raspberry Pi from Go
- blink an LED connected to a Pi header pin
- read button or sensor state via GPIO input
- communicate with SPI devices from a Raspberry Pi
- generate PWM signals on a Pi pin
- set pull-up or pull-down resistors on GPIO pins

## When to choose
- you want GPIO access in Go with no external C library dependencies
- you're targeting Raspberry Pi hardware including Pi 4
- you need SPI, PWM, or edge detection alongside basic GPIO

## When to avoid
- you need GPIO on non-Raspberry-Pi single-board computers
- you're on a platform without /dev/gpiomem or /dev/mem access
- you need a maintained library with active development

## Facets
- artifact type: library
- maturity: maintenance
- function: embedded, sdk
- domain: iot, embedded-systems, hardware
- platform: go, embedded
- tags: gpio, raspberry-pi, bcm2835, spi, pwm, hardware-interfacing, no-cgo, linux
