摘　　要：概要介绍了EPP模式并口及CAN总线,详述了虚拟设备驱动程序VxD的概念和作用,并着重说明了在EPP模式并口和CAN总线的接口实现中对于VxD的具体应用。结合该应用,提供了一套CAN总线通信实验系统。系统应用VxD驱动程序,成功地实现了PC的EPP模式并口和CAN适配卡之间的接口,能很好地完成两者之间的信息传输,及时响应中断信号和实现CAN总线的实时网络通信功能。EPP model parallel port and CAN bus are generally introduced. The definition and use of virtual device driver VxD are specified. Also, the application of VxD driver in the interface realization of EPP model parallel port and CAN bus is focused on. Combining with the VxD application, an EPP-CAN based experimental communication system is introduced. Using VxD driver, this system successfully realizes the interface of CAN bus and EPP model parallel port. It can well accomplish the information transmission between them and response interruptions in time, thus realizes the real-time net communications of CAN bus.
