摘　　要：PS/2鼠标作为一种无源输入设备,因其耗电极少、可靠性高、价格低廉,接口设计方便,保密性好等优点,在一些人机交互系统的界面设计中或是需要设定较多参数的单片机的嵌入式系统中,应用优势非常明显。设计者在单片机上扩充鼠标接口,编制鼠标驱动程序。本文在分析PS/2协议和PS/2鼠标通信原理及驱动问题的基础上,讨论了鼠标驱动中的关键问题,并给出了在ATmega16开发板上、在icc开发环境下鼠标驱动程序的设计实现。PS/2 mouse, as a inactive input device, has many good features ,such as seldom power, high reliability,low prices, convenient interface design, better confidentiality and so on. According to these good features, it has great advantages in some interactive system interface design and embedded systems with many parameters of monolithic integrated circuits. Designers enlarge the interfaces in the SCMC and write the driver for the PS/2 mouse. The article deals with the main problems of the driver of the mouse on the basis of the analysis of the PS/2 protocol and the communication principles and driver of the mouse. And the article also gives out the design of the driver on a atmega 16 development board in the icc development environment.
