Implementation of PS/2 Mouse and Keyboard Based on Windows CE

This paper introduces the detailed proposal about implementation of PS/2 mouse and keyboard based on Windows CE5.0 operating system. First, the external Microprocessor Control Unit (MCU) communicates with embedded processor through universal serial port; then it exchanges data with PS/2 device and realizes the translation protocol from PS/2 to serial port; at last the system realizes PS/2 mouse and keyboard. This paper introduces how to drive PS/2 mouse and keyboard in the Windows CE5.0 operating system and how to design hardware and software of MCU in detail.
