Wireless USB Optical Mouse Designer’s Kit

Design Guide

Introduction

Reference Design Overview

This design guide describes the design of a low power The image-based optical mouse sensor takes snap shots

consumption optical mouse using the Texas Instrument of the surface it is navigating on. It measures changes in

MSP430F1222 microcontroller, the Avago ADNS-3040 position by comparing the sequential images (frames) and

optical sensor and a 27 MHz FSK transmitter implemented mathematically determines the direction and magnitude

with discrete components. The receiver is implemented

with a TI TRF9700 receiver and Cypress CY7C63743 USB

controller. The document discusses the reference design

of movement. The traditional duel-channel optical encoder

generates the quadrature Z-wheel movement signals.

This design guide illustrates the hardware connection of

hardware and the ﬁrmware implementation. Included a LED-based optical mouse with standard conﬁguration;

in Appendix A is the schematic for this reference design

mouse. The software section of this document describes

the architecture of the ﬁrmware required to implement

the mouse functions. The MSP430F1222 data sheet is

available on the TI web site at www.ti.com. The ADNS-3040

data sheet is available from the Avago web site at www.

avagotech.com. USB controller data sheet can be found

on the Cypress web site: www.cypress.com

as well as the ﬁrmware management and the handling of

the USB protocols. USB protocol provides a standard way

of reporting mouse movement and button presses to the

PC. The Windows HID driver interprets the USB data and

performs the cursor movements and mouse clicks.

The functional block diagram of the reference design

mouse is shown in Figure 1. The optical sensor detects

the X and Y movements. An optical quadrature encoder

provides the Z-wheel movement. Each of the button

switches is pulled up normally and provides a Ground

when pressed. The MAX1722 boost regulator maintains

the 2.7 V operating voltage for the reference design mouse

from two regular AA Alkaline batteries in parallel.

Key reference design objectives:

1. Highlight the low-power beneﬁt of the ADNS-3040

2. Demonstrate multiple RF technologies: 27 MHz and

2.4 GHz

3. Feature a Flash-based development environment to

facilitate rapid ﬁrmware changes
