[Abstract]:This paper introduces the EZ-USBFX2 chip integrated with microprocessor, and expounds the design method and implementation scheme of a general interface of virtual instrument based on USB. The related circuit design is completed and the internal program language description of USB microprocessor and FPGA to realize the specified function is given. The design based on USB makes the interface more versatile, and the application of high compatibility FPGA simplifies the circuit design and has great expansibility. The peripheral circuit design improves the interface function and improves the interface performance. The interface has been successfully applied to some university laboratories and scientific research units.
