ℹ️ Since 2024, GC2 has taken over maintenance of the project, supporting new OS versions as well as current hardware generations. We are dedicated to keeping the arguably best-performing GPIO Library for Raspberry Pi running smoothly. We strive to do our best, but please note that this is a community effort, and we cannot provide any guarantees or take responsibility for implementing specific features you may need.

⚠️ on Pi5, PWM support is currently under development and will not work at this point. If you’re interested in the progress, please check the corresponding issue.

WiringPi (Unofficial Mirror/Fork)

This is an unofficial mirror/fork of wiringPi to support ports (Python/Ruby/etc). With the end of official development, this repository has become a mirror of the last “official” source release, plus a fork facilitating updates to support newer hardware (primarily for use by the ports) and fix bugs.

• The final “official” source release can be found at the final_source_2.50 tag.
• The default master branch contains code that has been written since that final source release to provide support for newer hardware.

Ports

wiringPi has been wrapped for multiple languages:

• Node - https://github.com/WiringPi/WiringPi-Node
• Perl - https://github.com/WiringPi/WiringPi-Perl
• PHP - https://github.com/WiringPi/WiringPi-PHP
• Python - https://github.com/WiringPi/WiringPi-Python
• Ruby - https://github.com/WiringPi/WiringPi-Ruby

Support

Please use the issue system of GitHub. Please do not email Gordon or @Gadgetoid. Please don’t email GC2 for reporting issues, you might contact us for anything that’s not meant for the public.
