Fake RPi.GPIO drop in replacement for testing and development

fake-rpigpio

fake-rpigpio is a package intended to provide a lightweight (dependency-free) fake interface for Raspberry Pi GPIO. The GPIO functions match those in the RPi.GPIO library, however the functions do nothing. This makes it easier to test GPIO-related code and to get the code to run on non-pi machines.

Installation

This package can be installed via pip:

pip install fake-rpigpio

Usage

A basic example of using this package to run with RPi.GPIO on a Pi and fake-rpigpio on a non-Pi:

try:
    import RPi.GPIO
except (RuntimeError, ModuleNotFoundError):
    import fake_rpigpio.utils
    fake_rpigpio.utils.install()

This will install fake-rpigpio.RPi as RPi and fake-rpigpio.RPi.GPIO as RPi.GPIO, so you should not need to change imports for the RPi.GPIO library.
