利用MSCOMM串口通信控件進行異步串行通信的VC程序設(shè)計

1、利用MSCOMM串口通信控件進行異步串行通信的VC程序設(shè)計一 課程設(shè)計題目 利用MSCOMM串口通信控件進行異步串行通信的VC程序設(shè)計二 課程設(shè)計要求 環(huán)境要求：Windows95/98/2000/XP功能要求：能將鍵盤上輸入的數(shù)據(jù)發(fā)送到另一臺計算機上；能將接收到的數(shù)據(jù)顯示到屏幕窗口內(nèi)；了解常用通信網(wǎng)絡(luò)設(shè)備的操作和應(yīng)用，掌握常用的通信協(xié)議的工作原理，能利用Visual C+、開發(fā)工具完成相應(yīng)的通信程序的設(shè)計工作。學(xué)習簡明地介紹自己的設(shè)計工作。三 課程設(shè)計目的 用Visual C+編程工具主機提供的接口，解決網(wǎng)絡(luò)用戶之間的交互式對話問題。進一步深入掌握網(wǎng)絡(luò)設(shè)計和通信程序的設(shè)計原理。使學(xué)生對計算機

2、通信網(wǎng)絡(luò)的設(shè)計實現(xiàn)有較深的了解，培養(yǎng)較高的通信網(wǎng)絡(luò)設(shè)計能力。四 程序思路硬件連接方面：數(shù)據(jù)的發(fā)送和接收由軟件控制，不進行硬件握手，其連接方法如圖真正需要互相連接的是RXD、TXD和GND；軟件方面：串行端口的本質(zhì)功能是作為CPU和串行設(shè)備間的編碼轉(zhuǎn)換器。當數(shù)據(jù)從 CPU經(jīng)過串行端口發(fā)送出去時，字節(jié)數(shù)據(jù)轉(zhuǎn)換為串行的位。在接收數(shù)據(jù)時，串行的位被轉(zhuǎn)換為字節(jié)數(shù)據(jù)在Windows環(huán)境（Windows NT、Win98、Windows2000）下，串口是系統(tǒng)資源的一部分。應(yīng)用程序要使用串口進行通信，必須在使用之前向操作系統(tǒng)提出資源申請要求（打開串口），通信完成后必須釋放資源（關(guān)閉串口）。VC+ 6.0提供

3、的MSComm控件通過串行端口發(fā)送和接收數(shù)據(jù)，為應(yīng)用程序提供串行通信功能。使用非常方便。在當前的Workspace中插入MSComm控件。在mscomm.h中加入MSComm控件。protected: CMSComm m_ComPort;在mscomm.cpp:OnCreare(中：DWORD style=WS_VISIBLE|WS_CHILD; if (!m_ComPort.Create(NULL,style,CRect(0,0,0,0,this,ID_COMMCTRLTRACE0("Failed to create OLE Communications Controln"

4、;return -1; / fail to create.打開并初始化串口void CComDlg:OnOpencom( if(m_Com.GetPortOpen( /打開通信端口m_Com.SetPortOpen(FALSE;m_Com.SetCommPort(1; /選擇com1if( !m_Com.GetPortOpen(m_Com.SetPortOpen(TRUE;/打開串口MessageBox("串口已經(jīng)打開"elseMessageBox("不能打開串口！"m_Com.SetSettings("9600,n,8,1" /波特

5、率9600，無校驗，8個數(shù)據(jù)位，1個停止位 /以字符串的形式設(shè)置并返回波特率、奇偶校驗、數(shù)據(jù)位、停止位m_Com.SetInputMode(1; / 定義Input屬性獲取數(shù)據(jù)的方式（為0：文本方式；為1：二進制方式）。m_Com.SetRThreshold(1; /為1表示有一個字符引發(fā)一個事件m_Com.SetInputLen(0; /設(shè)置每次Input讀入的字符個數(shù)，缺省值為0，表明讀取接收緩沖區(qū)中的全部內(nèi)容m_Com.GetInput(;m_opened=TRUE;捕捉串口事項。MSComm控件可以采用輪詢或事件驅(qū)動的方法從端口獲取數(shù)據(jù)。我們介紹比較使用的事件驅(qū)動方法：有事件（如接收到

6、數(shù)據(jù)）時通知程序。在程序中需要捕獲并處理這些通訊事件。在MainFrm.h中：protected:afx_msg void OnCommMscomm(;DECLARE_EVENTSINK_MAP(在ComDlg.cpp中：BEGIN_EVENTSINK_MAP(CComDlg, CDialog/AFX_EVENTSINK_MAP(CComDlgON_EVENT(CComDlg, IDC_MSCOMM2, 1 /* OnComm */, OnComm, VTS_NONE/AFX_EVENTSINK_MAPEND_EVENTSINK_MAP( / 映射ActiveX控件串口讀寫.完成讀寫的函數(shù)的確

7、很簡單，GetInput(和SetOutput(就可。兩個函數(shù)的原型是：VARIANT GetInput(；及 void SetOutput(const VARIANT& newValue;都要使用VARIANT類型（所有Idispatch:Invoke的參數(shù)和返回值在內(nèi)部都是作為VARIANT對象處理的）。無論是在PC機讀取上傳數(shù)據(jù)時還是在PC機發(fā)送下行命令時，我們都習慣于使用字符串的形式（也可以說是數(shù)組形式）。查閱VARIANT文檔知道，可以用BSTR表示字符串，但遺憾的是所有的BSTR都是包含寬字符，即使我們沒有定義_UNICODE_UNICODE也是這樣！ WinNT支持寬字符

8、, 而Win95并不支持。為解決上述問題，我們在實際工作中使用CbyteArray，給出相應(yīng)的部分程序如下：void CComDlg:OnComm( / TODO: Add your control notification handler code hereVARIANT variant_inp;COleSafeArray safearray_inp;LONG len,k;BYTE rxdata2048; CString strtemp;if(m_Com.GetCommEvent(=2 variant_inp=m_Com.GetInput(; safearray_inp=variant_in

9、p;len=safearray_inp.GetOneDimSize(;for(k=0;k safearray_inp.GetElement(&k,rxdata+k;for(k=0;k BYTE bt=*(char*(rxdata+k; strtemp.Format("%c",bt; m_recv+=strtemp; UpdateData(FALSE;五 程序調(diào)試運行程序后顯示用戶交互界面：打開串口：在一臺終端上的輸入情況：在另一臺終端上的輸出情況：六 心得體會對于這次課程設(shè)計，對于自己來說是個比較大的挑戰(zhàn)，因為以前從沒有做過這樣的課程設(shè)計，即雙機通信。心理沒底，但是

10、要提高自己，就要做自己不敢做的事情。由于不懂，所以開始找了很多資料，對于雙機通信，理論知識我很快就掌握了，主要是串口的開啟與關(guān)閉，串口初始化以及串口的選擇，數(shù)據(jù)基本就可以傳輸了，經(jīng)過思考，發(fā)現(xiàn)理論知識比較簡單，但是我原來接觸的語言是C和java，從來沒有接觸過C+，感覺無從下手，而且熟悉visual C+環(huán)境也需要一段時間。萬事開頭難，剛剛開始的兩天思路很亂。后來仔細看了一下題目，是用mscomm控件來實現(xiàn)，在網(wǎng)上查詢了相關(guān)資料后，發(fā)現(xiàn)mscomm的學(xué)習還是很簡單的，通過控件操作，竟然可以自動生成VC框架，這樣我自己就只要考慮串口的初始化和數(shù)據(jù)傳輸就可以了。VC具有強大的功能，能夠節(jié)約程序員的

11、時間，使程序員在編程時能很快地構(gòu)造出程序的框架，而專注于數(shù)據(jù)傳輸。數(shù)據(jù)傳輸實現(xiàn)就較為簡單了，不像文件傳輸，需要封裝文件。我參考網(wǎng)上實現(xiàn)串口的資料，然后就實現(xiàn)了程序的傳輸。這樣相當于單工通信。在程序傳輸實現(xiàn)之后，我還有一周的時間，我就在此基礎(chǔ)上進行改進，在程序中設(shè)置mscomm控制兩個串口，這樣就需要兩個mscomm控件,而硬件要求是，電腦中必須有兩個串口，但是一般電腦中只有一個串口，好在同學(xué)那里有一個擴展串口，我在一臺電腦上編實現(xiàn)了兩個串口的數(shù)據(jù)傳輸，相當于半雙工通信。七 附件程序Com.cpp #include "stdafx.h"#include "Com.h
