基于Labwindows/CVI的USB与PC机的通信

Communication from the USB Device to the Computer Based on the Labwindows/CVI

文章介绍了Labwindows/CVI中的VISA(虚拟仪器软件结构)在测试应用程序开发中的优点,简单描述了利用VISA驱动器生成向导安装USB驱动程序的步骤,主要讲述了使用VISA函数库进行USB与PC机数据通信的软硬件实现方法并给出了软件设计程序中的主要函数代码。

The article presents the merits of the VISA（ Virtual Instrumentation Software Architecture） in the Labwindows/CVI when it is used in the development of the testing application , simply describes the process of installing the driver Driver with the VISA Development Wizard ,mostly narrate a software and hardware implement of communication from the USB device to the computer with the VISA function library and some important function codes in the software design are given.
