halcon/mfc利用serialport类制作串口通信对话框

一、修改serialport文件
上一节中可以实现发送数据但是不能接收数据,最后发现是serialport文件有问题,修改如下:

二、对话框相关函数
1.开关串口

    CString portnums;
    GetDlgItemText(IDC_IO, portnums);

    MyPublicData.Public_com = flag;

        if (!mySerialPort.InitPort(this, flag, CBR_9600, 'N', 8U, 1U, EV_RXCHAR)) MessageBox("initPort fail !");
        if (!mySerialPort.OpenListenThread()) MessageBox("OpenListenThread fail !");
        Isportopen = 1;
    }
    else  if (!mySerialPort.OpenListenThread()) MessageBox("OpenListenThread fail !");
    m_StateLed11.SetIcon(m_hIconLedGreen);
}


void IO::OnBnClickedguan()      //关闭串口
{
    // TODO:  在此添加控件通知处理程序代码
    mySerialPort.CloseListenTread();
    m_StateLed11.SetIcon(m_hIconLedRed);
}

2.发送数据

void IO::OnBnClickedButton17()  //发送数据
{
    // TODO:  在此添加控件通知处理程序代码
    CString buffer;
    GetDlgItemText(IDC_SEND, buffer);
    CByteArray receivedata;
     char *a = NULL;
    a = new char[];
    int receivedatalen;
    receivedatalen = Str2Hex(buffer, receivedata);
    for (int i = 0; i < receivedatalen; i++)
    {
        a[i] = receivedata[i];
    }
    mySerialPort.WriteData(a, receivedatalen);                    
    a = NULL;

}

清空编辑框;


void IO::OnBnClickedButton16()
{
    // TODO:  在此添加控件通知处理程序代码
    receivedt = "";
    UpdateData(FALSE);//读取编辑框内容
    //方法一:关联变量,把变量的值给空,再UpdateData(FALSE);
    //方法二:直接得到控件的指针,再设置其为空。如:
        //GetDlgItem(IDC_XXX)->SetWindowText(_T(""));//给它空的字符串,就没东西了。
}

3.接收数据

//声明一个消息响应函数
afx_msg LONG OnComm(WPARAM ch, LPARAM port);//串口字符接收消息  

//串口消息映射  
ON_MESSAGE(WM_COMM_RXCHAR, OnComm) 

//消息响应函数
