Design Guide
Introduction
This design guide describes the design of a low power
consumption optical mouse using the following compo-
nents:
This reference design kit provides a power efficient and
feature rich solution in one neat package.
The design guide discusses the reference design
hardware and firmware implementation. The document
starts with the basic operations of a computer mouse pe-
ripheral followed by an introduction to the Avago Tech-
nologies ADNS-7530 low power laser mouse sensor, the
Nordic Semiconductor nRF24L01 and nRF2401A trans-
ceivers, Texas Instruments MSP430F1222 microcontroller
and Silicon Laboratories C8051F326 USB controller. The
software section of this application note describes the
architecture of the firmware required to implement
the mouse and the USB dongle functions. Included in
Appendix A is the schematic for this reference design
mouse and USB dongle.
The Avago Technologies ADNS-7530 laser mouse sensor,
an 16-pin integrated molded lead-frame staggered dual
inline package (DIP), is based on LaserStream
ogy, which measures changes in position by optically
acquiring sequential surface images (frames) and math-
ematically determining the direction and magnitude of
movement. Its high performance, low power architecture
is capable of sensing high-speed mouse motion while
prolonging battery life, two performance areas essential
in demanding wireless applications.
The ADNS-7530 sensor along with the ADNS-6150, ADNS-
6160-001 and ADNS-6170-002 lens, form a complete
and compact laser mouse tracking system. There are no
moving parts, which mean high reliability and less main-
tenance for the end user. In addition, precision optical
alignment is not required, facilitating high volume
assembly.
