Hi!
Im trying to comunicate an Arduino with Qt Creator throw the Serial Port.

The result gives the following error:

QObject::connect: (receiver name: 'MainWindow')
Thanks for your help

Hi and welcome to devnet,

Are you sure you declared a slot with that name in your MainWindow class definition ?

Something like:
@
public slots:
void serialReceived();
@

[josetomas]

I declared it as a private slot
@private slots:
void serialReceived();@

[SGaist]

Did you implement it ?

[josetomas]

yes
@ connect(serial,SIGNAL(readyRead()),this,SLOT(serialRecieved()));@
that calls:
@void MainWindow::serialReceived()
{
QByteArray ba;
ba=serial->readAll();
ui->label->setText(ba);
qDebug()<<ba;
}

Possibly a typo? You've got "serialRecieved" in the connect call and "serialReceived" as the member name.
