Emulate PS/2 Wheel Mouse

[ajt]

Does anyone know of some sample code for using a PIC to act as a wheel mouse when connected to a PS/2 connector on a PC?

I have found countless articles on the PS/2 interface and several assembler code examples for using a PIC to act as 2 button PS/2 mouse but I cannot find an example in CCS C (or any C code that matter).

The application I have is to sense 3 switches and the wheel with a PIC and emulate the PS/2 interface to send the data to a PC. I don't need to sense and send the X or Y mouse data but will send all zero's in those bytes.

Thanks

You could check the code library here........
also there's USB examples that might be helpful in the examples folder...
