Design Guide
Introduction
This design guide describes the design of a low power
consumption optical mouse using the Texas Instrument
MSP430F1222 microcontroller, the Avago ADNS-3040
optical sensor and a 27 MHz FSK transmitter implemented
with discrete components. The receiver is implemented
with a TI TRF9700 receiver and Cypress CY7C63743 USB
controller. The document discusses the reference design
hardware and the firmware implementation. Included
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
Key reference design objectives:
1. Highlight the low-power benefit of the ADNS-3040
2. Demonstrate multiple RF technologies: 27 MHz and
3. Feature a Flash-based development environment to
2.4 GHz
facilitate rapid firmware changes
specifications, features, capabilities, functions, release dates, and remove availability of the product(s) at anytime.

Reference Design Overview
The image-based optical mouse sensor takes snap shots
of the surface it is navigating on. It measures changes in
position by comparing the sequential images (frames) and
mathematically determines the direction and magnitude
of movement. The traditional duel-channel optical encoder
generates the quadrature Z-wheel movement signals.
This design guide illustrates the hardware connection of
a LED-based optical mouse with standard configuration;
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.
