Abstract
Now,USB interface in computer is very popular,and widely used in the serial communication between devices and computer.Considering the problem that the general and transplantable application about USB communication and its interface module,to reduce the pressure for the development cycle of USB device design,this paper provided an interface solution based on PDIUSBD12 which contains USB firmware interface in MSP430 and USB applications interface in PC.The experimental results show that this solution can be stable and reliable for the communication between host and devices,and this interface solution could be easy and reliable to transplant to the other associated systems.
