基于VB的串口通讯.doc

内蒙古科技大学毕业设计说明书（毕业论文） 摘 要 Visual Basic6.0是一种功能强大的Windows应用程序的开发工具，它具有众多的特点，提供了面向对象的可视化的程序设计方法，是开发Windows应用程序的一种方便而简捷的方法。本文主要介绍了利用VB提供的串行通信控件开发串行通信的详细过程，已经如何利用VB6.0中的MSComm控件实现pc机与单片机的通信，同时在功能上也提供了不少简便之处。着重讲述了软件设计的全过程，分别阐述了串口的初始化，数据的接收与发送，串口配置的初始化与实现，以及PC机与单片机的通信。 本软件具有收发数据及时准确，无遗漏数据现象出现，并对传输中出现的错误能够检验并实现纠正功能。适合于对数据传输的准确性有较高要求的场合使用，而且具有方便实用，操作简单等特点。 关键字：Visual Basic 6.0；串行通信；MSComm；单片机 内蒙古科技大学毕业设计说明书（毕业论文） Abstract Visual Basic 6.0 is a powerfully functional exploit tool for windows application programming. It has many distinguishing features, offered Object-Oriented visual programming tools. So it is convenient and simply means for Windows applications.The detailed process of developing serial communication, using the serial communication facilities offered by VB, is mainly introduced In this article. The most important part is about the whole process of software designing, which includes the initialization, the data’s receiving and sending, the serial disposal’ initial and achieving of correcting code and verifying code. It mainly refers to VB and serial communication, the rules of correcting and verifying. The software has some functions such as receiving and sending data in time and exactly, never missing data verifying and correcting mistakes transmitted. It is suitable to be used in the occasion which needs high accuracy. What’s more, it is easy to use and operate.This project is a successful application of VI in measurement domain,which testifies that VI is an available and effective solution and can be employed to accomplish majority complicated measurement task.
