How we can read particular string/data from any device to print on particular LCD in qt?

@Mohit-Tripathi said in How we can read particular string/data from any device to print on particular LCD in qt?:

void Dialog::updateLCD(QString sensor_reading)
{
ui->temp_lcdNumber_2->display(sensor_reading);
ui->temp_lcdNumber_3->display(sensor_reading);
}

As already explained several times: you are updating both temp_lcdNumber_2 and temp_lcdNumber_3 with the same value each time you call that function.

@SGaist
As per discussion above, I have defined that if I make two functions, I get both write values on one LCD. But, if I define one function :

void Dialog::updateLCD(QString sensor_reading)
{
ui->temp_lcdNumber_2->display(sensor_reading);
ui->temp_lcdNumber_3->display(sensor_reading);
}

I get the same value on both LCD.

But, my question was "how can I get the one input in one only LCD if we have multiple LCD widget?". I have mentioned in my comment as well as question.
I have used two different functions, same functions and two arrays also. Please go through my recent code in above comment.

That's simple and what @J-Hilk showed in his example. Properly parse the data you receive and update each LCD separately.

Is this a right way to write the data of two textEdit using pushbutton. I think that I am storing both values in one string that's why I am getting the both values on one LCD widget.

void Dialog::on_pushButton_clicked()
{
    QString output1 = ui->lineEdit->text();
  //  qDebug()<<output1;
    QString output2 = ui->lineEdit_2->text();
   // qDebug()<<output2;
    if(arduino->isWritable())
    {
         arduino->write(output1.toStdString().c_str());
        arduino->flush();
         arduino->waitForBytesWritten(500);
         arduino->write(output2.toStdString().c_str());
         arduino->flush();
         arduino->waitForBytesWritten(500);
         qDebug()<<output1;
         qDebug()<<output2;
    }
}

Don't @ the moderators unless you have an issue requiring moderation.

Depending on the content of your line edit, you can use toLatin1() or toUtf8() rather than making these two conversions.
