Introduction

This design guide describes how a cost-effective

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

using the Avago Technologies high performance ADNS-

3080 optical mouse sensor and Cypress Semiconductor

CY7C63743-PXC USB microcontroller. The document

starts with the basic operations of a computer mouse

peripheral followed by an introduction to the ADNS-

3080 optical mouse sensor and CY7C63743-PXC USB

microcontroller. A schematic of the ADNS-3080 optical

mouse sensor to the CY7C63743-PXC USB microcontroller

buttons of a standard mouse is also shown in this docu-

ment. 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 measures changes in position by opti-

cally acquiring sequential surface images (frames), and

mathematically determining the direction and magni-

tude of movement. The Z-wheel movement is done in the

traditional method by decoding the quadrature 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-3080 Optical Mouse Sensor

Avago’s ADNS-3080 optical mouse sensor is used in this

reference design as the primary navigation engine. This

Optical Navigation Technology contains an Image Acqui-

sition System, a Digital Signal Processor, and a four-wire

serial port. The CY7C63743-PXC periodically reads the

ADNK-3083

Optical Mouse Designer’s Kit

Design Guide

ADNS-3080’s Delta_X and Delta_Y registers to obtain any

horizontal and vertical motion information happening

as a result of the mouse being moved. The four-wire syn-

chronous serial port is used to set and read parameters in

the ADNS-3080, and to read out the motion, Delta_x and

Delta_y information. This motion information is reported

to the PC updating the position of the cursor. The advan-

tages of using the ADNS-3080 optical sensor are: best

tracking accuracy, sensor programming flexibility via SPI

port, and the automatic frame rate feature (1000fps to

6400fps). The ADNS-3080 also has selectable resolution

of 400cpi or 1600cpi. Furthermore, the ADNS-3080 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-sup-

plied firmware file contents into the ADNS-3080. 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.
