  • 注册MSCOMM
    • MFC实现
      • 测试

一. 注册MSCOMM

1.下载控件MSCOMM32.OCX(32位)
百度网盘链接链接:

https://pan.baidu.com/s/1pf8js-BNhL1Mh1XvYoFetw

提取码:

z45s

2.把这个ocx文件放在c盘WIndows的system32里，打开cmd执行：

regsvr32 MSCOMM32.OCX

(32位)
3.在c盘WIndows的syswow64里，打开cmd执行：

regsvr32 c:\windows\syswow64\mswnisck.OCX

(64位)
4.在上面三步之后，如果还是有问题，可以执行下面的操作
把内容存为.reg文件。

Windows Registry Editor Version 5.00.reg

双击导入注册表即可。

二. MFC实现

1.首先创建MFC 对话框的项目，在对话框中添加按钮，输出框这些
右键点击对话框，选择

Insert ActiveX Control

选择其中的

在这里插入图片描述
然后点击ok结束
在这里插入图片描述
然后给控件添加变量，可以参考下面的链接
用vc给控件添加变量

  1. 给电话形式的控件添加变量,变量名为m_mscom,之后项目中会出现对应.h和.cpp文件
  2. 加Eidit Control控件用于接受消息，绑定变量m_EditReveive
  3. 添加串口控件事件处理处理程序（点击电话，选择event，点击Oncomm，完成)
  4. 给按钮添加一个点击事件（在event中添加）OnBnClickedButtonOpen()

代码

  1. 在主cpp中找到点击按钮的事件，添加打开串口函数
void CMyDlg::OnDoubleclickedButton1() 
{
	// TODO: Add your control notification handler code here
	//初始化
	if (!m_mscom.get_PortOpen())     //初始化串口
    {
        m_mscom.put_CommPort(4); //选择串口
        m_mscom.put_InputMode(1);     //设置输入方式为二进制方式
        m_mscom.put_Settings(_T("9600"));   //波特率为（波特率组A合框）无校验，8数据位，1个停止位
        m_mscom.put_InputLen(1024);   //设置当前接收区数据长度为1024
        m_mscom.put_RThreshold(1);    //缓冲区一个字符引发事件
        m_mscom.put_RTSEnable(1);     //设置RT允许
        m_mscom.put_PortOpen(true);   //打开串口
    }
}

在CMscomm.h中找的如下代码

    // 操作
public:

在public中添加下述代码

    // IMSComm

    // Functions
    //

  1. 添加自动接收代码（项目中通信协议是测试结果自动上传），并直接显示在接收控件中，代码如下：
void CMyDlg::OnOnCommMscomm1() 
{
	// TODO: Add your control notification handler code here
	//判断是否有数据接受
    if (m_mscom.get_CommEvent() == 2)
    {

        char str[1024] = { 0 };            
        long k;
        VARIANT InputData = m_mscom.get_Input(); //读缓冲区
        COleSafeArray fs;
        fs = InputData; //VARIANT型变量转换为COleSafeArray型变量
        for (k = 0; k<fs.GetOneDimSize(); k++)
			fs.GetElement(&k, str + k);	//转换为BYTE型数组
 
		m_EditReveive += str;      //	接收到编辑框里面
		//SetTimer(1,10,NULL);		//延时10ms
		UpdateData(false); //更新到控件
	}
}

三. 测试
