Qextserialport crashes

[martinpetkovic]

Hello to everyone

I made a simple code for communication with a lpc2138 board through com port but my code chrashes after about 10 seconds, I made my code in lpc to send data all the time.
Here are the source files:

untitled.pro
@QT += core gui

TARGET = untitled
TEMPLATE = app

SOURCES += main.cpp
untitledmainwindow.cpp

HEADERS += untitledmainwindow.h

FORMS += untitledmainwindow.ui

include(C:/Users/Martin/Desktop/qextserialpor/src/qextserialport.pri)@

main.cpp
@#include <QtGui/QApplication>
#include "untitledmainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
untitledMainWindow w;
w.show();

return a.exec();

}
@

untitledmainwindow.h
@#ifndef UNTITLEDMAINWINDOW_H
#define UNTITLEDMAINWINDOW_H

#include <QMainWindow>
#include "qextserialport.h"

namespace Ui {
class untitledMainWindow;
}

class untitledMainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit untitledMainWindow(QWidget *parent = 0);
~untitledMainWindow();

private slots:
void onDataAvailable();

private:
Ui::untitledMainWindow *ui;
QextSerialPort *port;
};

#endif // UNTITLEDMAINWINDOW_H@

untitledmainwindow.cpp
@#include "untitledmainwindow.h"
#include "ui_untitledmainwindow.h"

untitledMainWindow::untitledMainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::untitledMainWindow)
{
ui->setupUi(this);

port = new QextSerialPort("COM9");
port->setBaudRate(BAUD9600);
port->setDataBits(DATA_8);
port->setParity(PAR_NONE);
port->setFlowControl(FLOW_OFF);
port->setStopBits(STOP_1);
port->open(QIODevice::ReadOnly);

connect(port, SIGNAL(readyRead()), this, SLOT(onDataAvailable()));

}

void untitledMainWindow::onDataAvailable()
{
QByteArray data;
data.resize(1);

port->read(data.data(), data.size());

ui->lineEdit->setText(data.data());

}

untitledMainWindow::~untitledMainWindow()
{
delete ui;
}@

Please help!!

Instead of QextSerialPort try use "QtSerialPort":http://qt-project.org/wiki/QtSerialPort.

I try to adapted your code on my serial port reader. I have no crash, I'm using qextserialport 1.2. In what line stops(crash) your application ?

I made a delay in the lpc code, I send 10 bytes in second, and now its ok.
Anyway thank you kuzulis and cincirin
