Abstract
A MCU USB data acquisition system was designed,which had controller USB2.0 in AT89C5131 chip.It is difficult to develop USB device driver,using a traditional method.Thus,one develops a USB driver based on NI-VISA (Virtual Instrument Software Architecture) in LabVIEW environment,which can realize the data communication between the PC and MCU.
