摘要
针对USB主机控制器在操作U盘、摄像头等USB设备过程中的重要作用,本文展示了一种基于USB接口芯片SL811和ARM芯片LPC2106的嵌入式通用USB-Host控制器,并就其设计思想、工作原理、操作过程、硬件电路和固件程序的实现方法,以及应用示例展开了讨论。
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.
