| Abstract: | This paper analyzes the design and implementation of the USB host controller in embedded system. The hardware connection and the software architecture of USB host system are demonstrated, in which the control core is C8051F021 controller chips. Mass Storage class programming and FAT16 file system software design are given. The system guides USB host system into embedded system, and expands the USB applications. |
