摘　　要：介绍了WDM驱动程序模型结构及其运行机理 ,结合皮秒时间相关单光子计数光谱仪的PCI总线数据采集卡设计 ,对驱动程序设计过程中的关键技术如存储器映射 ,I/O访问 ,中断请求 ,驱动程序与应用程序间的通信等做了讨论 ,给出运用NuMega公司的DriverStudio和VisualC++开发的程序实例。最后对驱动程序的安装。The mode structure and principle of the WDM driver are illuminated in this paper. Taking PCI bus sample card design as a reference, author discusses some key techniques in programming the WDM driver such as memory mapping, the accessing to I/O port, the requesting for interrupt and the communication between application and driver. On the base of these discussion, an example driver that developed under DriverStudio and Visual C++ 6.0 is given. In the last, author of this paper introduces techniques to modify the inf file of WDM driver and the usage of SoftICE which is a useful tools during debugging driver.
