摘要
针对现有的USB设备无法脱离PC机操作的局限性,介绍了一种利用单片机控制USB主机接口芯片SL811HS的嵌入式USB主机设计方案。系统由单片机、USB主机接口控制器和高速双端口RAM等设备组成。重点分析了系统的原理,并且给出了硬件设计方案和主机软件的系统结构。
A method adopting a single -chip computer to control the USB interface chip SL811HS to realize an embedded USB host was introduced due to the limitation that the existing USB device fails to work without a PC. This system is composed of an MCU - USB host controller and a high - speed dual - port RAM. The priniple of the system was analyzed. The system structure of hardware designing and the host software were also presented.
