摘要
目前USB接口得到了广泛的应用,但是这种应用仅仅局限在PC机与各种外设之间,而外设与外设之间却无法利用USB接口进行通信。本文采用SL811HS作为USB接口芯片,利用单片机AT89C52并通过软件及硬件设计,实现了USB之间的通信,硬件成本较低,并具有实际应用价值。
The USB interface is used widely, but it is used only between PC and other USB devices. A AT89C52 - based system is proposed in the paper to make the USB devices to communicate with each other.
