摘　　要：简要介绍了设备驱动程序的概念以及设备驱动程序的开发工具,讨论了基于WinDriver的驱动开发模式,设计了适合CAN总线适配卡的驱动程序。开发过程为,利用VC++6.0对设备驱动程序的功能函数以DLL(DynamicLinkLibraries)的方式进行封装,通过调用DLL导出函数完成对低层相关操作。在DLL与上层可执行应用程序中采用回调函数来完成各种中断信号的中断处理。The conception and development tools of the device driver program is introduced, the model of driver development of PC extended cards based on WinDriver is discussed, and a CAN bus adapter driver is developed based on WinDriver. All the API functions of device driver are exported from a DLL(Dynamic Link Libraries) by Visual C++6.0, which makes hardware operation easier and more convenient. In order to improve real time of interruption process, callback function is used in communication between DLL and application when interruption happens.
