A small MIT-licensed C library providing userspace access to Linux peripheral I/O interfaces including GPIO, LED, PWM, SPI, I2C, MMIO, and Serial. It consolidates the native Linux APIs into a simple, dependency-free static library for embedded Linux platforms like Raspberry Pi and BeagleBone.

Use cases

• read and write GPIO pins from userspace C code on a Raspberry Pi
• communicate with I2C sensors in an embedded Linux application
• drive SPI devices from C without writing raw ioctl code
• blink or control LEDs via the Linux LED subsystem
• generate PWM signals for motors or servos
• open and read from serial ports in a C program
• memory-mapped I/O access to hardware registers on BeagleBone

When to choose

• you need C access to GPIO, SPI, I2C, PWM, serial, LED, or MMIO on embedded Linux
• you want a dependency-free static library with a simple re-entrant API
• you are targeting Raspberry Pi, BeagleBone, or similar single-board computers
• you want a maintained wrapper over the native Linux peripheral APIs

When to avoid

• you are not on Linux
• you need Python, Lua, Java, or Dart bindings (use the periphery ports instead)
• you need a higher-level robotics framework with device drivers and abstractions
• you need interrupt-driven or real-time guarantees beyond what userspace Linux provides
