【摘要】 根据现在工程数据采集的需求 ,结合并口及增强型并口 (Enhanced Parallel Port,EPP)工作方式的特点 ,设计了以并口作为外设和主机的通讯接口的数据采集方案 ,并在现有主流桌面操作系统 Windows2 0 0 0下 ,以系统原有的并口驱动为基础 ,采用新的窗口驱动模式 (Windows DriverMode,WDM)实现了该数据采集驱动软件。系统运行稳定 ,速度可以满足需求。更多还原

【Abstract】 In order to meet the requirement of engineering-oriented data acquisition, we design the project using parallel port as the communication interface between peripheral device and host according to the operation characteristics of parallel port and Enhanced Parallel Port. Then, based on Windows 2000 OS and its existing parallel port driver, we realize the data acquisition driver software working in Windows driver mode, which runs stably and can meet the requirement.更多还原
