Optical Mouse Designer’s Kit

Design Guide

Introduction

This design guide describes how a cost-effective combi-

nation USB-PS/2 yet feature-rich optical mouse can be

built using the Avago Technologies high performance

ADNS-3060 optical mouse sensor and Cypress Semi-

conductor CY7C63743-PC USB microcontroller. The

document starts with the basic operations of a computer

mouse peripheral followed by an introduction to the

ADNS-3060 optical mouse sensor and CY7C63743-PC

USB microcontroller. A schematic of the ADNS-3060

optical mouse sensor to the CY7C63743-PC USB micro-

controller buttons of a standard mouse is also shown in

this document. The software section of this design guide

describes the architecture of the firmware required to

implement the USB and PS/2 mouse functions.

Optical Mouse Basics

The optical mouse measureschanges in position by

optically acquiring sequential surface images (frames),

and mathematically determining the direction and

magnitude of movement. The Z-wheel movement is

done in the traditional method by decoding the quadra-

ture signal generated by optical encoder. This design

guide shows how to connect to and manage a standard

configuration of mouse hardware, as well as handle

the USB and PS/2 protocols. Each of these protocols

provides a standard way of reporting mouse movement

and button presses to the PC.

Introduction to ADNS-3060 Optical Mouse Sensor

Avago’s ADNS-3060 optical mouse sensor is used in

this reference design as the primary navigation engine.

This Optical Navigation Technology contains an Image

Acquisition System, a Digital Signal Processor, and a

four-wire serial port. The CY7C63743-PC periodically

reads the ADNS-3060’s Delta_X and Delta_Y registers

to obtain any horizontal and vertical motion informa-

tion happening as a result of the mouse being moved.

The four-wire synchronous serial port is used to set

and read parameters in the ADNS-3060, and to read

out the motion, (triangle)x and (triangle)y information.

This motion information is reported to the PC updating

the position of the cursor. The advantages of using the

ADNS-3060 optical sensor are: best tracking accuracy,

sensor programming flexibility via SPI port, and the

automatic frame rate feature (1000fps to 6400fps). Fur-

thermore, the ADNS-3060 sensor has excellent tracking

performance on difficult surfaces such as wood and half-

tone surfaces. Additionally, the Burst mode is another

special serial port operation mode which may be used

to reduce the serial transaction time for three predefined

operations: motion read, SROM download, and frame

capture. Speed improvement is achieved by continuous

data clocking to or from multiple registers during this

operation.

Motion Read is activated by reading the Motion_Burst

of the Motion, Delta_X, Delta_Y, SQUAL, Shutter_Upper,

Shutter_Lower and Maximum_Pixel registers in that

order. SROM download uses Burst Mode to load the

Avago-supplied firmware file contents into the ADNS-

3060. The firmware file is an ASCII text file with each 2-

character byte (hexadecimal representation) on a single

line. Frame Capture is a fast way to download a full array

of pixel values from a single frame.
