PCI数据采集卡WDM驱动程序设计

The key technology of WDM driver for PCI data sample card

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.给出了运用NuMega公司的Driver Studio和VisualC++开发的程序实例.最后对驱动程序的安装、编译及调试工具做了介绍.

This paper illuminates the mode structure and principle of the WDM driver.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.
