PC Pointer

This is a very simple PS/2 to serial mouse protocol converter which uses a PIC micro-controller and MAX232.

Schematics

Two schematics are presented for two different PIC micros. It should trivial to port this application to any controller you have using this project.

Install

First install gputils for gpasm and Pickle for ICSP (if you are using a Velleman K8048 for example).

Fetch the source and assemble the code.

hg clone http://hg.kewl.org/pub/PCPointer
cd PCPointer
make

Now program the chip. Here I use Pickle.

p14 program pic16f688.hex

Usage

Plug an old PS/2 mouse or newer USB mouse with PS/2 support into the input port of the circuit. Connect the serial output into the RS232 input of your old computer.

Boot into DOS and detect the mouse with MOUSE.COM 8.20.

MOUSE.COM /C1

Disable it like this.

MOUSE.COM OFF
