摘要
随着数据传输速度越来越快,通讯接口要越来越简单,采用高速通用串行口进行通讯成为大多数嵌入式设计的首选,也符合现代电子技术设计特点-小型化。而现有的串行通信技术慢速的有RS232、I2C、SPI,高速的有USB、1394、truboC等,但这些只是物理层协议,对于数据链路层没有进行定义,本文设计了一种通用串口通讯协议,方便广大设计人员灵活设计数据通讯。
with the faster and faster data transmission speed,communication interface to be more and more simple,the use of high speed universal serial port for communication has become the first choice of most embedded design,but also in line with modern electronic technology design characteristics-miniaturization.However,the existing serial communication technologies are RS232,I2C,SPI with slow speed,USB,1394,truboC with high speed,etc.,but these are just physical layer protocols,and the data link layer is not defined.This paper designs a general serial port communication protocol,which is convenient for designers to flexibly design data communication.
