The software that actually performs the joystick override function is available below for download. It should run under Python 3.5 or newer, with proven functionality under Raspberry Pi OS (previously called Raspbian) installed on Raspberry Pi 2 Model B V1.1 or V1.2.

• • Download the joyverride_1.7.zip zip file

Notes:
Current software version is 1.7 (see below for versions history).
The software is published under the GPLv3 license.

Important: the software is tied to the JOyVerride hardware implementation; there is no guarantee that it will work properly in other embodiment and I have no intention to provide support outside of the specific purpose for which I created it.

As a side note, given that the JOyVerride unit uses high quality hardware debouncers per each GPI input, the software itself does not compensate for any switch contact bouncing and thus avoids the need for additional time loops that may slow down the program execution speed – an aspect that is especially important when multiple joysticks are pressed in very quick sequence.
