| Abstract: | Universal Serial Rus (USB) is an emerging external bus employed in connecting peripherals with PC. The virtue of USB comes from its ability of being shared in essence. In USB system, the devices can be attached and detached without turning off the power supply. It is intelligent and expansive as well as apt to reduce the complexity of development of new peripherals. This paper presents USB protocol Revision 1.1, the principle and implementing method of this bus . And according to the construct and principle of the chip USBN9602, the process of how to design the hardware and software of the USB interface circuit is described here. |
