说明：  单片机串口通信模板，Keil工程打包，包括两种单片机8051和C8051F020. 有多机通信协议，数据格式为“起始码+本机地址+数据”，模板中已建立接收数据、命令处理、数据发送等流程，极大地方便了串口通信的开发
(Packaged single chip computer serial communication templates, Keil projects, including two and 8051 MCU C8051F020. How machine communication protocols, data format for "start code+ the machine address+ data", established receives the data template, order processing, and data process, has made great development of serial communication)
