摘要
根据现有的工程数据采集的需求,结合并口及增强型并口(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Windows2000下,以系统原有的并口驱动为基础,采用新的窗口驱动模式(WDM)实现了该数据采集驱动软件;经测试,系统运行稳定,速度可以满足需求。
In order to meet the requirement of engineering-oriented data acquisition, we designed a scheme using parallel port as the communication interface between periphery device and host considering the specifics of working characteristic of parallel port and enhanced parallel port. Then, based on windows2000 OS and its existing parallel port driver, we realized the data acquisition driver software working in windows driver mode. Test shows that the software runs stably and can meet the requirement.
