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

This article details a USB project interfacing an ADNS-2620 optical mouse sensor with Windows XP/Vista using a PIC18F2550 microcontroller. The system utilizes the TD-USB-01 board for USB communication and connects to the sensor via SPI. It offers real mouse functionality, a 324-pixel CCD sensor, and upgradable software via RS232.

Parts used in the TD-USB-01 interface with mouse sensor board:

  • PIC18F2550 microcontroller
  • TD-USB-01 board
  • ADNS-2620 optical mouse sensor
  • Mini-B USB connector
  • SPI 4-wire flatcable
  • Windows XP/Vista compatible PC
  • RS232 bootloader

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.
