| Abstract: | As a new technology of interface, USB is very popular for its convenience in use and rapidness in transferring data. But the development of USB is very difficult, because of the complicated interface protocol and the response to the windows operating system. In this article, the design of hardware, the software programming and application of USB interface are demonstrated. The firmware programming and relavant problems are discussed in detail. The application of USB interface in Mass Storage is given. PC can recognize devices easily and perform data reading and writing through USB interface. With the application of the DSP in the field of digital signal processing, USB interface will have a comprehensive application in the DSP development system. |
