lgpio is a library for Linux Single Board Computers (SBC) which allows control of the General Purpose Input Outputs (GPIO).

Features

  • reading and writing GPIO singly and in groups

  • software timed PWM and waves

  • callbacks on GPIO level change

  • notifications via pipe on GPIO level change

  • I2C wrapper

  • SPI wrapper

  • serial link wrapper

  • daemon interface

  • access control (daemon interface)

  • file handling (daemon interface)

  • creating and running scripts (daemon interface)

  • network access (daemon interface)

Archive components

The base library

  • The lgpio C library to control local GPIO.

The daemon

  • The rgpiod daemon offers a socket interface to the lgpio library.
  • The rgpio C library to control local and remote GPIO via the daemon.

Python modules

  • The lgpio Python module to control local GPIO.
  • The rgpio Python module to control local and remote GPIO via the daemon.

Utilities

  • The rgs shell utility to control local and remote GPIO via the daemon.

Documentation

See http://abyz.me.uk/lg/

Example programs

See http://abyz.me.uk/lg/examples.html and the examples in the EXAMPLES directory.

GPIO

ALL GPIO are identified by their gpiochip line number.

Download & Install

Prerequisites

A few packages are needed during installation of the Python modules.

  • the SWIG code generator (to build lgpio.py from the C library)
  • the Python development files (to build lgpio.py)
  • the Python set up tools (to install lgpio.py and rgpio.py)

On Debian like systems these packages may be installed with the following commands.

sudo apt install swig python-dev python3-dev
sudo apt install python-setuptools python3-setuptools

Download & Install

wget https://github.com/joan2937/lg/archive/master.zip
