ARM系列单片机与PC机之间的串行通信

The Design of Serial Communication Interface between ARM and PC

论述了实时监测系统中ARM单片机与PC机之间的通信方法,介绍了ARM系列单片机与主机串行通信的结构框图与硬件接口电路,讲述了下位机通信程序的设计方法和上位机通讯的软件实现,并给出了上下位机通讯的流程图。在通信的过程中,需要设定相同的通讯协议才能保证通信的正常。

This paper discusses communication method between ARM single chip and PC in Real-time monitor system. It introduces structure diagram and serial communication interface circuit between the ARM single chip microcomputer and host computer. It also introduces the design of hypogenous machine of communication program and upper machine communication. Moreover, it gives communication flowcharts. In the process of communication, the proper communication can be guaranteed only on the condition of the same protocol setting.
