pigpio is a C library for the Raspberry Pi that provides fine-grained control of GPIO pins, including PWM, servo pulses, callbacks, and software-implemented serial, I2C, and SPI links. It also ships a daemon, a Python module, and command-line utilities exposing the same functionality over socket and pipe interfaces.

Use cases

• control GPIO pins on a Raspberry Pi from C or Python
• generate PWM signals to dim LEDs or drive motors
• send servo control pulses to multiple servos simultaneously
• read button presses with microsecond-accurate timestamps via callbacks
• bit-bang software serial, I2C, or SPI on arbitrary GPIO pins
• build arbitrary waveforms with precise output timing
• monitor and log digital signals with piscope

When to choose

• you need microsecond-level timing accuracy for GPIO on a Raspberry Pi
• you want PWM or servo control on many pins at once in software
• you need to control GPIO remotely over a socket or pipe interface
• you want software serial/I2C/SPI on any user GPIO

When to avoid

• you are targeting boards other than the Raspberry Pi
• you need a maintained library with active development (the project is in maintenance mode)
• you only need simple, slow-speed GPIO toggling where lighter libraries suffice
• you are working with Raspberry Pi 5, which pigpio does not support
