Abstract:
A tilt-wheel mouse circuit is provided. Without adding more I/O pins, the tilt-wheel mouse circuit provides extra scrolling-left and scrolling-right functions through an external-extend circuit and firmware of a micro-controller within the tilt-wheel mouse circuit. It follows that the cost of the manufacturing of the tilt-wheel mouse is accordingly low and the package size of the micro-controller is accordingly small.
