摘　　要：为了让用户应用程序能以一种规范的方式打开、关闭、读、写带有PCI接口的硬件,提出在用户应用程序与硬件之间建立一座桥梁,使它能够完成上述功能。首先利用微软的驱动程序开发包将驱动程序所包含的基本例程编写完毕,然后再编写用户应用程序,此应用程序就可以通过调用基本例程来达到访问硬件的目的。采用DM642中集成的PCI接口,使用DDK开发工具,开发出的驱动程序通用性好,兼容性强,使板卡与PC机的通信速度得到了很大的提高。In order to make the application open, close, read and write the hardware with the PCI interface through a standard means,expecting to establish a bridge between the application and the hardware which can accomplish the purpose. Firstly,using the Device Driver Kit （DDK） to write the basic example program which is the necessary part of a driver. Then making the application work by calling the basic example program to access the hardware. Adopting the PCI interface integrated in the DM642 and the DDK emboldened by the Microsoft. The driver has a strong compatibility and can non - limit used by other hardware,also increases the speed of the communication between the application and the driver greatly.
