摘要
硬件是基于PCI总线的CAN和RS485异步串行通信接口的适配卡,在Windows2000操作系统下,利用Driver Works开发它的WDM驱动程序来完成数据传输.简单介绍了开发工具及硬件结构,重点介绍了驱动程序与应用程序之间的通信、中断处理等一些重要模块,并给出了相应的程序,对其中的关键语句作了简单的说明,最后对调试过程中常见的问题作了概括.
The hardware is the adapter of CAN and RS485 asynchronous serial communication interface on PCI bus. In Windows2000 operating system, Driver Works is employed to develop the WDM driver in order to transfer data. The developing tools and its hardware configuration are firstly demonstrated, then some important modules are presented, such as the communications between driver and application program, interrupting management, etc. The corresponding programs are given. The key statements in the program are given a brief explanation. Finally, the common problems in debugging process are summarized.
