Data acquisition,as an integrated application technology,mainly focuses on information data acquisition,storage,processing and control and has a strong practicability.With such features as hot -swappable,plug and play,less system resource occupancy,etc.,USB technology has been rapidly and widely used.USB2.0 is used due to its fast theoretical transfer speed of 480Mbps.Combined with latest development of USB interface of both interior of country and abroad,the USB architecture is deeply studied.The interface design of C8051F340 microcontroller USB 2.0 is described for the hardware. USBXpress software development kit,from CygnaVSilicon,is used for the software,which conducts USB interface program design for devices such as C8051F340 to provide a complete software solution for both upper and lower computers.APP of upper computer,as a way of communication with customers,is used to accept and present data of hardware.
