Hi,
Does anyone know a good way to interface a microprocessor to the joystick port of a PC?
I found out that one can use an 'digital potentiometer' which is a chip that can be serial controlled and has 4 digital resister in it.
I have seen a german site where they sold an trainer-joystick interface based on an atmel uc, that had a little circuit witch a transistor and some other components between the uc and the joystick port (i forgot the url of the site).
Does anyone know an other cheap and small way to accomplish this?
