Abstract: This paper describes the interface and protocol used by PS/2 keyboard and how to connect the PS/2 keyboard to a MCU. This paper sets 8051 equipped with a LCD as a minimum system and realizes the input process of PS/2 keyboard. Furthermore, it discuss the realize of graphical interfaces of embedded devices with PS/2 mouse.

Keywords: PS/2 interface; Bidirectional synchronous serial protocol
