扩展单片机通信能力的方法

The Method of Expanding Single-chip Microcomputer Communication Capability

介绍了一种新的单片机通信方法 ,可以用P3口或P1口的任意两位作为收发 ,用软件的方法构成异步通信。程序中使用了表决程序 ,从而有效地滤除了干扰 ,稳定可靠。

The paper introduces the new method of single chip microcomputer communication, which can use any two bit of P3 or P1 to receive or transmission and form asynchronous communication with the software. In the program, it adopts the voting procedure to filter the interference effectively.
