Hi all does anybody know of an convertor from mouse system or microsoftmouse or ps2 mouse back to its origin quadrature out put sounds stupid but interests me . I once saw someone did a project generating quadrature output from joystick inpu t what about analog to quadrature. I think it is a matter of just up and down counting or left right shifting but i remember that my old atari crached if an non logikal state entered at the mouse input found out by replacing the mouse with a new one somtimes it crached somtimes not.
