| Abstract: | A single-chip USB interface method is designed based on the USB interface chip EZ-USB FX2 in this paper. The design uses EZ-USB FX2 chip to form the data pipeline between microprocessor and computer. The interface conforms to the USB2. 0 protocol. EZ-USB FX2 chip works in the Slave FIFO way. The chip can be connected with microprocessor conveniently by suitable configure. The microprocessor can access to FX2＇ s endpeint by the same way as access to external memory. Through the USB interface, the user application program can send corresponding order to the microprocessor and receive data from the micro- processor. To the design, the connection of hardware is convenient and the programming is simple. In this paper, beth the hardware design and the software design are discussed in great detail, including the firmware of the FX2 and the user application program of the computer side. |
