摘要
介绍了串行通信及红外发送/接收电路的工作原理,以及MAX232芯片的功能,在此基础上设计了一个可实现多功能通讯的实验板,该实验板可通过RS 232接口实现单片机与PC机之间的串行通信,并集成了RS 485接口可进行远距离通信的实验,还可利用红外接口实现多机间的无线通信实验。
This paper introduces the theory of serial communication and infrared circuit, a multi- function experimental board are designed for communication based on these theories. The board can achieve serial communication between personal computer and single chip microcomputer based on RS 232,copied with RS 485 long distance communication can be experimentalized. Infrared communication of multi - computer can also be realized by infrared port.
