| Abstract: | 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. |
