This reference design provides power efficient feature-rich solution small slim package. design guide discusses reference design hardware firmware implementation. document starts with basic operations computer mouse peripheral followed introduction Avago ADNS-3530 power optical mouse sensor, Nordic Semiconductor nRF2402 transmitter nRF2401A transceiver, Texas Instruments MSP430F1222 microcontroller. software section this application note describes architecture firmware required implement mouse dongle functions. Included Appendix schematic this reference design mouse dongle. ADNK-3533-TN24 power slim optical mouse utilizes ADNB-3532 power Light Emmiting Diode (LED) slim mouse sensor bundle. mouse bundle small form factor (SFF) illuminated navigation system. bundle consists integrated chip-onboard (COB) mouse sensor ADNS-3530 lens ADNS-3150-001. ADNS-3530 low- power optical navigation sensor. new, low-power architecture automatic power management modes, making ideal batteryand power-sensitive applications such cordless input devices. ADNS-3530 capable high-speed motion detection 20ips addition, onchip oscillator integrated minimize external components. ADNS-3530 along with ADNS-3150-001 lens form complete compact mouse tracking system. There moving parts which means high reliability less maintenance user. addition, precision optical alignment required, facilitating high volume assembly. bundle sensor programmed registers through four-wire serial port. packaged surface mountable package.
Introduction ADNS-3530 Optical Mouse Sensor
ADNS-3530 based Optical Navigation Technology, which measures changes position optically acquiring sequential surface images (frames) mathematically determining direction magnitude movement. ADNS-3530 contains Image Acquisition System (IAS), Digital Signal Processor (DSP), four wire serial port. acquires microscopic surface images lens illumination system. These images processed determine direction distance motion. calculates relative displacement values. external microcontroller reads information from sensor serial port. microcontroller then translates data into PS2, USB, signals before sending them host game console. learn more about sensor's technical information, please visit Avago site http://www.avagotech.com/
