摘要
基于PC机对目标系统的控制需要,考虑到USB总线传输速度高、支持热拔插等突出优点,提出了一种基于MSP430F249单片机和一款USB-TO-UART桥接芯片TUSB3410的USB接口设计方案,通过USB接口实现PC机与目标系统的通信。详细介绍了MSP430F249单片机和USB-TO-UART桥接芯片TUSB3410的特点以及本接口的硬件设计方法和软件实现方案。该设计结构简单、成本低、适用范围广,具有很好的市场前景,可以在对电焊机参数的采集以及PC机对电焊机的控制上加以推广应用。
Because of the eontrol acquisition of current real-time data system and the advantages of USB bus such as high transmission speed,hot-swappable support,proposed a USB interface design based on MSP430F249 MCU and a USB-TO-UART bridge chip TUSB3410,to achieve the communication between the PC and target system during USB.Elaborated MSP430F249 MCU and the USB-TO-UART bridge chip TUSB3410,the hardware and software design methods.The design structure is simple,low cost,wide application and has good market prospects.h also can be used in electric welding parameters＇ acquisition,as well as PC-control of the welding machine.
