WiringPi is a fast C library for accessing GPIO pins on Raspberry Pi boards by directly manipulating hardware registers. It also ships with a gpio command-line utility for inspecting and controlling pins from the shell.

Use cases

• control gpio pins on raspberry pi from c
• blink an led with a raspberry pi
• read button input with pull-up resistors on a pi
• generate pwm signals on raspberry pi gpio
• read all gpio pin states from the command line
• build a home automation controller on a raspberry pi

When to choose

• you need low-latency, high-performance GPIO access on a Raspberry Pi in C or C++
• you want a mature, widely adopted GPIO library with a simple Arduino-like API
• you need a CLI tool to inspect and toggle pins without writing code

When to avoid

• you are targeting non-Raspberry-Pi hardware
• you need GCLK functionality on the Raspberry Pi 5, which is not yet supported
• you prefer a higher-level language like Python (e.g., gpiozero or RPi.GPIO)
