TD-USB-01 interface with mouse sensor board using PIC18F2550

This is an example USB project showing how to interface an optical mouse sensor (the ADNS-2620) with a standard XP/Vista computer.

The TD-USB-01 board with a PIC18F2550 communicates with:

  • the PC: USB 2.0 through a mini-B connector.
  • the mouse sensor board: SPI over 4-wire flatcable.

Here are the technical specifications:

  • PC Win XP/Vista interface application with Visual C# 2008 Express: free download.
  • TD-USB-01 (green pcb on top) with PIC18F2550 USB HID setup.
  • Mouse sensor board (046) with ADNS-2620.
  • USB Bus powered, no external power supply needed.
  • ADNS-2620 registers selection stored in the windows registry.
  • Refresh rate from 1mS up.
  • Data bits & bytes details.
  • Real mouse functionality.
  • Sensor CCD 324 pixels: image displayed: 18×18, 6-bit greyscale.
  • TD-USB-01 software is 100% upgradable with a simple RS232 bootloader.
  • RS232 interface for raw data readings.
  • PCB Dimensions: 40 x 41 mm or 1″57 x 1″61
