Continiously store data from QSerialPort



  • Hello Everyone

    I want to record data from a device which is connected to my computer with USB. I can communicate with the device. Now i want to record the data from the device continuously and stored it. So to do this should i have to set the buffer length? If yes then how can i do it. Please help.
    Thanks in advance

  • QFile* storage=new QFile("storage.dat",serial);
    storage->open(QFile::WriteOnly);
    QObject::connect(serial,&QSerialPort::readyRead,[=]()->void{storage->write(serial->readAll());});
    


  • Hello @VRonin
    I couldnt get your answer.
    if you refer following topic i want store data continuously. I am using NI device to record data from a sensor. I know how to communicate and read write the NI device using DAQmx libraries.
