摘要
串行口是嵌入式芯片的基本端口,使用场合很多。一般只能实现一对一的通信和一对多的通信。而往往会碰到要求多个芯片实现多点间任意通信的问题。该文给出了利用串口构成令牌环网的硬件方法以及软件编程方法,很好地解决了多点间自由通讯的问题,具有一定的理论和使用价值。
Serial port is a basic port embedded chip, the use of a number of different ways. Can only achieve one-to-one communications and one-to-many communication. Requirements often encounter a number of chip multi-point communication between any of the issues. In this paper, constitute the use of serial token ring network hardware and software programming methods, a very good solution to the multi-point communications between the issue of freedom, has a certain theoretical and value.
