【Abstract】 This paper is dedicated to develop kernel Win98 WDM device for the real time video signal capture PCI card based on the fusion878A.The relating backward,technologies of device driver are described.Flow of the stream minidriver is discussed and developing steps of minidriver,including the relating program,is represented.Ultimately,the debugging method of the WDM driver is depicted simply.Experiment proves that the WDM driver can capture and preview the video signal in real time,and work well.更多还原
