- 串行通信MCS-51单片机内部有一个全双工的串行通信口,即串行接收和发送缓冲器(SBUF),这两个在物理上独立的接收发送器,既可以接收数据也可以发送数据。但接收缓冲器只能读出不能写入,而发送缓冲器则只能写入不能读出,它们的地址为99H。这个通信口既可以用于网络通信,亦可实现串行异步通信,还可以构成同步移位寄存器使用。-MCS-51 microcontroller serial communication within the a full-duplex serial communication

- 此程序是用汇编语言开发的,可以用于51单片机串口通信,压缩文件中包含程序运行时的所有文件。-This program is developed in assembly language, can be used for 51 single-chip serial communication, compressed file contains all the files when the program is running.
单片机(双核系统)
- 用了51单片机的ID工作方式,使没有HOLD功能的51单片机能够直接通过片外RAM进行数据通信。不但硬件和软件的实现都比较简单,数据传输速度快,而且不涉及高成本特殊器件,实现“双核系统”。(With 51 MCU ID works, make no HOLD function of 51 single-chip microcomputer can directly through the external RAM data communication. Not only the realizat
