The interface technology of virtual instruments and USB has received close attention in the field of instrument research and development. The use of USB interfaces for intelligent peripherals for data acquisition and control has improved its bottleneck phenomenon and also strengthened its "affinity" with general-purpose computers. Ordinary MCS-51 The microcontroller does not have a USB interface, and LabVIEW, one of the virtual instrument application software development platforms, does not provide a driver for the USB interface. For this reason, the design principles of virtual instruments based on USB and LabVIEW and the USB development method are introduced, and a method of USB development is proposed.
