Serial comunicacion using Qt and Visual Studio

Falcon2050

Hello :
I would like to ask you very kindly about how to realize a serial communication using Qt and Visual Studio.
Here is the code I have up to now :

//mytimer.hpp
@
#ifndef MYTIMER_HPP
#define MYTIMER_HPP

#include <QtSerialPort/QtSerialPort>
#include <QTimer>
#include <QThread>
#include <QObject>

class MyTimer : public QObject
{
Q_OBJECT

public:
MyTimer(int,int);
QSerialPort serial;
QTimer timer;
int how_many_times;
int sampling;

signals:
void done();

public slots:
void MyTimerSlot();
};

#endif // MYTIMER_H
@

//mytimer.cpp
@
//#include <QtSerialPort/QtSerialPort>
#include "mytimer.hpp"
#include <QDebug>

MyTimer::MyTimer(int a, int b)
{
how_many_times = a;
sampling = b;

connect(&timer, SIGNAL(timeout()),

this, SLOT(MyTimerSlot()));

timer.setInterval(sampling);
timer.start();

}

void MyTimer::MyTimerSlot()
{

if (how_many_times == 1)
{
timer.stop();
}

/==========================================================================/

serial.setPortName("COM1");
serial.setBaudRate(QSerialPort::Baud9600);
serial.setDataBits(QSerialPort::Data8);
serial.setParity(QSerialPort::NoParity);
serial.setStopBits(QSerialPort::OneStop);
serial.setFlowControl(QSerialPort::NoFlowControl);
serial.open(QIODevice::ReadWrite);

serial.write("hello");

serial.close();

/==========================================================================/

qDebug() << "hello" ;

how_many_times -= 1;

if (how_many_times == 0)
{
done();
}

}
@

//main.cpp
@
#include <QCoreApplication>
#include "mytimer.hpp"

int main(int argc, char *argv[])
{
QCoreApplication a(argc, argv);

MyTimer timer(20,500);

QObject::connect(&timer, SIGNAL(done()), &a, SLOT(quit()));

return a.exec();
}
@

Thank you in advance for your response,
Have a nice day!
