Duan Tian-ming

Abstract

Since the USB host controller plays an important role in the operation of USB flash disks,USB video recorders,and so on,This paper demonstrates an embedded USB-host controller based on the interface chip SL811 and ARM microprocessor LPC2106.The discussion is focused on its design scheme,working principle,operating process,and its implement method of hardware circuit and firmware program,as well as the application demonstration.
