使用QT自带库实现检测串口并且显示

QT的项目文件： pro

greaterThan(QT_MAJOR_VERSION, 4) {

    QT       += widgets serialport

} else {

    include($$QTSERIALPORT_PROJECT_ROOT/src/serialport/qt4support/serialport.prf)

}

TARGET = enumerator

TEMPLATE = app

SOURCES += \

    main.cpp

然后头文件包含

#include


QT_USE_NAMESPACE


    foreach (const QSerialPortInfo &info, QSerialPortInfo::availablePorts()) {
        QString s = QObject::tr("Port: ") + info.portName() + "\n"
                    + QObject::tr("Location: ") + info.systemLocation() + "\n"
                    + QObject::tr("Description: ") + info.description() + "\n"
                    + QObject::tr("Manufacturer: ") + info.manufacturer() + "\n"
                    + QObject::tr("Serial number: ") + info.serialNumber() + "\n"
                    + QObject::tr("Vendor Identifier: ") + (info.hasVendorIdentifier() ? QString::number(info.vendorIdentifier(), 16) : QString()) + "\n"
                    + QObject::tr("Product Identifier: ") + (info.hasProductIdentifier() ? QString::number(info.productIdentifier(), 16) : QString()) + "\n"
                    + QObject::tr("Busy: ") + (info.isBusy() ? QObject::tr("Yes") : QObject::tr("No")) + "\n";
    }

QSerialPortInfo类中封装了串口。其中QSerialPortInfo::availablePorts()表示检测到的串口中可用的串口.
