基于单片机的串口通信的设计.doc

摘 要 随着电子技术的不断发展，单片机的应用范围越来越广泛，在工业控制、家电控制、数据采集等多个领域都有着十分重要的作用，由于单片机的使用，越来越多的系统开始向智能化方向发展。而单片机自带的串口功能可以实现其与其他外设MCU或PC机之间的通信，这样就使得控制系统更加的方便实用，利用单片机的串口通信可以实现数据的远程传输、数据分析与系统综合控制功能，尤其是在数据量比较大的场合下，利用一个主机向各个从机发送控制指令是一个很好的解决方案，在这个过程中，串口通信是实现单片机与单片机之间通信的关键。 本文介绍了基于单片机的串口通信设计，通过按键输入数据，单片机通过串口将数据发送给另一个单片机，同时发送的数据均可在2个单片机控制的数码管上显示，以检测串口通信的准确性。本文介绍的方法简单易懂，可广泛应用于各种串口数据通信系统中。 关键词：单片机 数据 串口通信设计 Abstract Summary with the continuous development of electronic technology, wide scope of application of the single chip, industrial controls, appliance control, data acquisition, and so has a very important role in many areas, due to the use of single-chip computer, more and more systems are beginning to intelligent direction. And single tablets machine since with of serial features can achieved its and other peripherals MCU or PC machine Zhijian of communications, such on makes control system more of convenient practical, uses single tablets machine of serial communications can achieved data of remote transmission, and data analysis and system integrated control features, especially in data volume than larger of occasions Xia, uses a hosts to all from machine sent control instruction is a is good of address programme, in this process in the, serial communications is achieved single tablets machine and single tablets machine Zhijian communications of key. This article introduced the design of serial communication based on single-chip computer by pressing the input data, single-chip serial data to another microcontroller, while sending data are available at the 2 on a single-chip computer controlled digital tube display, accuracy to detect serial communication. Described in this method is simple and easy to understand, can be widely applied to various serial data communication systems.
