Abstract:Animing at disadvantages of the traditional USB equipment testing system, such as:single objective and poor universality, design a USB equipment wireless test system based upon LabVIEW.System with LabVIEW as software development platform for the virtual instrument front panel design and the preparation of the background program;Using wireless data transceiver module and other hardware equipment, build up the bridge between the host computer and the equipment of the wireless data communication;In STC12C5A MCU as the core controller, through the introduction of USB bus interface chip CH375 extend the USB-HOST function, enabling wireless acquisition and transmission between the host computer and the USB device data.This system is mainly used in the development process of debugging and testing USB devices.
