【Abstract】 This article introduces a method of the communication between FPGA and the USB host. The author succeeded in communicating with PC using a USB chip—— FT245BM, produced by FTDI (Future Technology Devices Intl. Ltd). A circuit diagram of the interface between the FT245BM chip and the FPGA chip is prepared. The program of FPGA, written in Verilog HDL, and the software running in PC are given;更多还原
