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

WiringPi is a performant GPIO access library written in C for Raspberry Pi boards.

This repository is the continuation of 'Gordon's wiringPi' which has been deprecated, a while ago.

• The last "old wiringPi" source of Gordon's release can be found at the final_source_2.50 tag.
• The default master branch contains code that has been written since version 2.5 to provide support for newer hardware as well as new features.

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.
