I just want to use FPGA to simulate a PC mouse to demonstrate a new motion detection algorithm. For the interface between the PC and the mouse(FPGA), I decided to use PS/2 cables. I have got a little documents about the PS/2, but it has a different protocol explications. So I am not sure which is the right one. Does some one can give me a real protocol which is used in current PC mouse. Thanks a lot -- Chao WANG EPFL | Ecole Polytechnique Fédérale de Lausanne STI IMT-NE ESPLAB Rue A.-L.
