Qt遍历串口以及串口操作

蔚落 2023-07-05 10:28 18阅读 0赞

# 一、添加串口模块 #

cmake中添加：

\#添加SerialPort模块 下面整句添加  
qt5\_use\_modules($\{PROJECT\_NAME\} Core SerialPort)

或者

find_package(Qt5Core  COMPONENTS Qt5SerialPort REQUIRED)

# 二、遍历串口 #

\#include <QtSerialPort/QSerialPort>//串口接口  
\#include <QtSerialPort/QSerialPortInfo>//串口接口信息

/**
     * @brief枚举出所有的串口，并寻找出指定描述Description的串口，比如NDI导航头的serialPortDescription可以在设备管理器中查看
     * NDI的serialPortDescription一般不会变，可用于自动识别串口
     *
    */
    std::string NDICAPI::getSerialPortName(std::string serialPortDescription)
    {
        std::string retPortName {};
        foreach (const QSerialPortInfo &info, QSerialPortInfo::availablePorts())
        {
           //通常通过串口名称进行连接，例COM1，所以在此处获取串口名称
    //        qDebug() << "Name : " << info.portName();
    //        qDebug() << "Description : " << info.description();
    //        qDebug() << "Manufacturer: " << info.manufacturer();
    //        qDebug() << "Serial Number: " << info.serialNumber();
    //        qDebug() << "System Location: " << info.systemLocation()<<"\n";
    
    
            if(serialPortDescription == info.description().toStdString())
            {
                #ifdef _WIN32 // Windows serial port implementation
                    retPortName = info.portName().toStdString();
                #else // Mac/Linux serial port implementation
                    retPortName = info.systemLocation().toStdString();
                #endif
            }
    
    
        }
    
    
        if(retPortName == "")
        {
            qDebug() << "can not find SerialPortName,please check serialPortDescription";
            std::cout << "Press Enter to continue...";
            std::cin.ignore();
            exit(-1);
        }
    
        return retPortName;
    }

# 四、Linux串口配置 #

注意：串口数据/t-/n的转换

config.c\_lflag &= ~(ICANON | ECHO | ECHOE | ISIG);  
    config.c\_iflag &= ~(INLCR| ICRNL | IGNCR);  
    config.c\_cc\[VMIN\] = 0;                  /\* use constant, not interval timout \*/  
    config.c\_cc\[VTIME\] =100/100; /\* wait time is in 10ths of a second \*/

注意：清楚缓存区

tcflush(fdComm\_, TCIOFLUSH);  
    tcflush(fdComm\_, TCIFLUSH);  
    tcflush(fdComm\_, TCOFLUSH); /\* clear input/output buffers \*/
