OPi.GPIO 0.5.1

A drop-in replacement for RPi.GPIO for the Orange Pi Zero

A drop-in replacement library for RPi.GPIO for the Orange Pi Zero and other SBCs. Only the basic GPIO functions are replicated, using sysfs: this allows the GPIO pins to be accessed from user space.

See the documentation for install instructions and detailed API usage.

Pull requests (code changes / documentation / typos / feature requests / setup) are gladly accepted. If you are intending to introduce some large-scale changes, please get in touch first to make sure we’re on the same page: try to include a docstring for any new method or class, and keep method bodies small, readable and PEP8-compliant. Add tests and strive to keep the code coverage levels high.
