PC与单片机串行通信的协议策略研究及应用

Research and application of communication protocol strategy between PC and single chip microcomputer

通信协议是串行通信系统正常运行的关键.通过对PC机与单片机多机串行通信协议中常见问题进行分析,提出了一种通信协议的制定策略.最后以某国际机场LED显示系统为例,完成了系统的通信协议制定和软件实现,验证了此策略在多机串行通信中的可靠性.

Communication protocol is a key factor in a serial communication system.It is analyzed that the usual problem in multi computer serial communication protocol between PC and single chip microcomputer,put forward that a kind of communication protocol strategy.At last,using the strategy,communication protocol and communication software of the LED display system in an international airport is developed,the reliability in multi computer serial communication is proved.
