PS/2 connector |

The PS/2 connector is traditionally used to connect mice and keyboards to computer systems. The connector uses six pins: clock, data, 5V, GND and two that are not connected. The PS/2 connector is fully documented here: PS/2 connector. We used a Parallax PS/2 to Breadboard Adapter for connect the optical mouse to the PIC18. Documentation and ordering information for the adapter can be found here: Breadboard Adapter. |

Original Assignment
Interface the PIC with a PS/2 optical mouse and display (x,y) position data on either an LCD screen (see, e.g., C Example: Serial LCD or C Example: Parallel Interfacing with LCDs) or the PC (e.g., in Matlab or hyperterminal).
