Hey everyone! I'm new to the forum, just a quick question.
I have found a Electric wheel chair controller at the Junk yard. Along with the entire base of the wheel chair the motors and battery charger.
From what I have found on YouTube in order to use the factory controller I need the factory joystick that communicates with the controller with RS 485 SharkBus.
How hard could it possibly be to decifer what kind of signals I need to send this controller on the RS 485 network to make it think that my Arduino board is the joystick for it?
Is this kind of stuff usually coded in a way that's non standard?
