| Abstract: | The USB interface has become one of the standard interfaces in real-time monitor and on-site debugging equipments.After comparied several methods to realize USB interface,FPGA and the USB chip of CH372 were chosen to realize the USB communication.This FPGA as the main chip,the controller was designed for CH372.The working principles and the state machine of the controller were discussed to meet the requirements of CH372’s timing and command input.Finally,the experimental platform was set up to verify the feasibility and effectiveness of the program. |
