摘要
详细介绍了一种基于COM组件技术的组态软件I/O设备驱动程序的设计方法。在分析了设计原理的基础上,给出了一种以太网数据服务器驱动程序的具体实现。COM组件驱动程序的进程内运行方式和被所有驱动程序组件支持的统一的协议接口,在组态软件和设备驱动程序之间建立了一条高效、无缝的通信连接,同时使整个驱动程序框架拥有非常好的可扩展性。
One method based on COM to design I/O device drivers for configuration software is detailed proposed. On the base of the analysis of the design theory, implementation of an example driver for a kind of Ethernet data server is concretely illustrated. In- process running type of COM component drivers and the uniform protocol interface supported by all driver components establish an efficient and seamless communication link between configuration software and device drivers, and also provide good extensibility for the whole driver framework.
