MSP430系统与PC机通信的USB接口设计

针对现行的USB计算机接口十分流行,广泛应用于设备与计算机的串行通信的现实性特点,考虑到USB通信其接口模块的通用性和可移植性问题,为减轻开发USB设备周期的压力,基于PDIUSBD12,设计了一个与MSP430单片机通信的USB固件接口,和与PC机相连接的应用程序的接口方案。实验结果表明,该方案能够在一定要求下稳定可靠地实现设备与主机之间的USB通信,其提供的接口程序可以简便可靠地移植到相关系统。

USB communication interface design between MSP430 system and PC

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.
