PC and MCU System Network Hardware Circuit Design

随着单片机的发展,其应用以从单机逐渐向多机或联网,而多机应用的关键又在于微机之间的相互通讯,互传数据信息。文章应用AT89C52单片机实现与计算机,多机之间主从式的串行通讯。并且在Visual Basic开发环境下,运用VB提供的通信控件,实现PC机与AT89C52单片机之间的串行通讯。

With the development of SCM, the pplication from the single gradually to the machine of net- wor,and multiple machine application and the key lies in microcomputer communication between, mutual informaton. This paper mainly introduces the application of single chip microcomputer serial interface serial communication,as well as the basic knowlege and the three communication interface standard. Based on AT89C52 MCLI and computer,multi machine serial communication between master and slave type. And in Visual Basic development environment, provided by VB communication control, the realization of PC and AT89C52 serial communication between mcu.
