Introduction Optical Mouse Basics
The Universal Serial Bus (USB) is an industry standard The optical mouse measures changes in position by
serial interface between a computer and peripherals optically acquiring sequential surface images (frames),
such as a mouse, joystick, keyboard, UPS, etc. This design and mathematically determining the direction and
guide describes how a cost-effective USB optical mouse magnitude of movement. The Z-wheel movement is done
can be built using the Sunplus, SPCP825A USB microcon- in the traditional method by decoding the quadrature
troller and the Avago Technologies ADNS-6000 optical signal ge
