Abstract
Based on USB controller CY7C68013A and radio frequency chip nRF2401,a data transmission system with wireless USB interface is designed,and the hardware software design of wireless USB interface is introduced.Comparing to the system of using multi-chip to realize USB interface,using single chip to design the USB interface enhances reliability of the system.Adopting FPGA as the down-side machine can improve flexibility and portability of hardware design.This system supports hot plug and play of USB interface,and also realizes wireless transmission for data without communication cable.
