做自己的串口调试工具-MFC

    之前一共说了几个软件库，串口通讯的，xml加载的，还有动态提示的，通过这三个库就可以实现一个自己的串口调试工具，成品如下

    

动态加载配置文件之后如下

软件可以在xml中配置发送的字符串，不算是大工程，但是灵活使用了之前的几个类库，上几个核心代码

首先是遍历系统串口，如下

//搜索系统当前串口，并实时显示在选择框中
    BYTE i = 0;
    CString str;
    str.Empty();
    ((CComboBox*)GetDlgItem(IDC_COMBO_PORT_SELECT))->ResetContent();//清除显示项
    for(i = 0; i < 255; i++)
    {
        if(SIO_OK == sio_open(i))
        {
             sio_close(i);
             str.AppendFormat("COM%d",i);
             ((CComboBox *)GetDlgItem(IDC_COMBO_PORT_SELECT))->AddString(str);
             str.Empty();
        }
    }
    i = ((CComboBox *)GetDlgItem(IDC_COMBO_PORT_SELECT))->GetCount();
    if(i ==0)
    {
        GetDlgItem(IDC_BUTTON_SERIAL_CONTROL)->EnableWindow(FALSE);
    }
    else
    {
        GetDlgItem(IDC_BUTTON_SERIAL_CONTROL)->EnableWindow(TRUE);
    }

打开串口如下

// TODO: 在此添加控件通知处理程序代码
    if(serial_isopen == TRUE)//此时需要关闭串口
    {
        if(com_port > 0)
        {
            if(sio_lstatus(com_port) >= 0)
                sio_close(com_port);
            com_port = 0;
        }
        serial_isopen = FALSE;
        ((CComboBox*)GetDlgItem(IDC_COMBO_PORT_SELECT))->EnableWindow(TRUE);
        ((CComboBox*)GetDlgItem(IDC_COMBO_BAUD_SELECT))->EnableWindow(TRUE);
        ((CComboBox*)GetDlgItem(IDC_COMBO_STOP_SELECT))->EnableWindow(TRUE);
        ((CComboBox*)GetDlgItem(IDC_COMBO_CHECK_SELECT))->EnableWindow(TRUE);
        ((CComboBox*)GetDlgItem(IDC_COMBO_DATA_BIT_SELECT))->EnableWindow(TRUE);
        ((CButton*)GetDlgItem(IDC_BUTTON_SERIAL_CONTROL))->EnableWindow(TRUE);
        ((CButton*)GetDlgItem(IDC_BUTTON_SERIAL_CONTROL))->SetWindowText("打开串口");
    }
    else
    {
        //获取当前选择的串口号码
        int i = 0;
        CString str;
        int config;
         if(-1==i)
         {
             MessageBox("请选择一个串口","失败",MB_OK);
             return;
         }
         else
         {
             ((CComboBox*)GetDlgItem(IDC_COMBO_PORT_SELECT))->GetWindowText(str);
             str = str.Mid(3,str.GetLength());
             i = atoi(str);
             //检测配置信息
             if(baud == 0x80)
             {
                 MessageBox("波特率未选择","错误",MB_OK);
                 return;
             }
             if(data_length == 0x80)
             {
                 MessageBox("数据长度未选择","错误",MB_OK);
                 return;
             }
             if(stop_bit == 0x80)
             {
                 MessageBox("停止位未选择","错误",MB_OK);
                 return;
             }
             if(check_mode == 0x80)
             {
                 MessageBox("校验模式未选择","错误",MB_OK);
                 return;
             }
            config = data_length|stop_bit|check_mode;
             //开始串口配置
             if( sio_open(i) != SIO_OK)
             {
                 MessageBox("串口打开失败","提示",MB_OK);
                 this->serial_isopen = FALSE;
                 com_port = 0;
                 return;
             }
            //运行到这里代表打开成功
            com_port = i;
            serial_isopen = TRUE;
            sio_flowctrl(com_port,0x00);//关闭硬件流控制
            sio_lctrl(com_port,0x00);//关闭RTS DTR
            sio_ioctl(com_port,baud,config);
            sio_flush(com_port,2);

            ((CComboBox*)GetDlgItem(IDC_COMBO_PORT_SELECT))->EnableWindow(FALSE);
            ((CComboBox*)GetDlgItem(IDC_COMBO_BAUD_SELECT))->EnableWindow(FALSE);

            ((CButton*)GetDlgItem(IDC_BUTTON_SERIAL_CONTROL))->SetWindowText("关闭串口");
         }
    }
