 TD-USB-02: USB TouchPad Interface

     

TD-USB-02 interface with touchpad sensor board and WinAmp interface.

This is an example USB project showing how to interface a touchpad sensor (the AD7142ACPZ) with a standard XP/Vista computer.

The TD-USB-02 board with a PIC18F2550 communicates with:

  • the PC: USB 2.0 through a mini-B connector.
  • the touchpad sensor board: SPI over 8-wire flatcable.
  • PC WinAmp application controls (start/stop, next/previous track, volume up/down).

Sensor example Source code (CCS C) , sensor board pcb layout and schematics (Eagle) available. 

Project updated: May 3, 2009.
