摘　　要：在Windows CE下GPIO是端口扩展器,当微控制器缺乏足够的I/O端口时,GPIO能够提供额外的控制和监视功能。本文分析了基于流驱动的GPIO驱动开发原理,以SC36410的GPM端口为例详细叙述了GPIO驱动开发过程,并给出了驱动程序的配置方法。GPIO（general input and output ports） in Windows CE can offer additional functions such as control and surveillance, when mi- croprocessor is short of adequate I/O ports. Principle of GPIO driver development based on stream driver is analyzed. Taking SC36410 as an example,the development process of GPIO driver is introduced,and the configuration method of driver is given.
