This is an unofficial fork of wiringPi which supports newer Linux distributions and kernel versions. This repository is a temporary Rhizomatica's WiringPi fork for use in HERMES project, which works on all versions of Debian Linux, and all Raspberries Pi up to and including version 4 (for Raspberry Pi 1 or early 2 revisions, edit wiringPi/wiringPi.c and change gpioLayout to 1). Raspberry Pi 5 support will be merged soon from upstream. An alternative to WiringPi is gpiolib, which is the Raspberry Pi Foundation's reference implementation for GPIO access.
No support is provided, but fell free to send PRs.
