摘要
针对虚拟仪器开发平台LabWindows/CVI中不提供直接支持USB接口函数库的情况,首先进行RS232和USB的接口转换,然后再利用CVI中RS232的函数库对USB进行数据读写,从而在LabWindows/CVI中实现USB通讯。
There is no direct function library for USB interface in LabWindows/CVI. In this situation, the interface conversion from USB to RS232 is realized, and then the development about reading or write USB interface with RS232 function library is implemented.And in this way USB communication has achieved in LabWindows.
