Main program source code published on GitHub:

Update last! First, need to update all devices but display. Because menu protocol is new and old devices will not be visible in the menu. After the update is finished hold the left button few seconds to exit the updated device menu. If the button does not work you may need to reset the power supply or replug the CAN cable in the display. After everything is updated - update the display. Make a controller reset (load defaults) after the update. We recommend running motor detect again on controllers. Detection of throttle/brake connected to display should be done in the display menu.
