Abstract:
The USB(Universal Serial Bus)-based chip PDIUSBD12 and the hardware design of its peripheral circuits are introduced in detail,as well as the firmware design on microprocessor AT 89C 52 for data exchange,WDM(Windows Driver Model) technology-based driver application design on Windows platform and MFC(Microsoft windows Foundation Class) technology-based test application design on Windows platform. Pinch points are summarized,such as the debugging for USB enumeration and driver application in WDM mode. Associated measures and experiences are provided.
Key words:  USB,RS - 485,data exchange,remote supervision,driver application
