摘要
在自动测试系统中,识别同类板卡需要分配不同的PID、VID,这种方法不仅操作复杂,而且不利于测试系统升级。为改进不足,提出一种通过驱动程序和应用程序的配合扫描硬件板卡的位置信息来识别同类硬件板卡的新技术。经测试表明,该技术实现了驱动共享的目的,达到了上位机对每个板卡分别读写操作的控制要求,并且简化了板卡的使用过程。
In the automatic test system,the method of recognizing similar boards needs the distribution of different PID and VID.This method is not only complicated to operate,but also not conducive to upgrade automatic test system.To address these problems,a novel technique,in which similar boards can be recognized by the information of hardware position scanned by the cooperation of driver program and application program,was proposed.The test results proved that driver sharing is realized by this method.In addition,the reading and writing operations of each board can be controlled respectively by PC and the application process of the board are simplified.
