CanOpen device EDS file to ObjectDictionary class

[Babs]

Hello i'm working on a CanOpen qml API.
The EDS file is a file describing CanOpen object dictionary of a device.
What i want to do is extract informations(entries,subentries) in my EDS file and add it to my object dictionary object.
My EDS File is structured like this

ObjectType=0x7
DataType=0x0007

And here is my ObjectDictionnary class header

#ifndef OBJECTDICTIONARY_H
#define OBJECTDICTIONARY_H
#include <QtCore/QtGlobal>


#include <QObject>
#include <QMap>
#include "qobjectdictionarydefs.h"

    Q_OBJECT

public:
    explicit ObjectDictionary(QObject * parent = Q_NULLPTR);

    void addEntry(QObjectDictionaryDataEntry *entry, const ObjDicIndex idx);
    bool hasEntry(const ObjDicIndex idx) const;
    bool hasSubEntry(const ObjDicIndex idx, const ObjDicSubIndex subIdx) const;
    QObjectDictionaryDataEntry* getEntry(const ObjDicIndex idx) const;

    void createPdoMappingEntry   (const ObjDicIndex idx);

    void     setMetaDataForObdPos (const ObjDicIndex idx, const ObjDicSubIndex subIdx, const QString & metaKey, const QVariant & metaData);
        QVariant getMetaDataForObdPos (const ObjDicIndex idx, const ObjDicSubIndex subIdx, const QString & metaKey) const;

public slots:
        void traverseObd();

signals:
    void beginObd(QObjectDictionary *obd);
    void beginEntry    (const ObjDicIndex    idx,    QObjectDictionaryDataEntry    * entry);
    void beginSubEntry (const ObjDicIndex subIdx, QObjectDictionarySubDataEntry *subEntry);
    void endSubEntry   (void);
    void endEntry      (void);
    void endObd        (void);


private:
    SparseArray<ObjDicIndex, QObjectDictionaryDataEntry *> m_entriesByIndex;

};

#endif // OBJECTDICTIONARY_H

I want to read entries and subentries from my EDS file and add it to my ObjectDictionary object.

I'm quite new at Qt.
Anyone can help?

Really doubtful that you are going to find anyone at the level you're looking for...at least without paying them.

Hi
About reading the EDS file.
It looks quite like ini format
QSettings might be able to read it
https://doc.qt.io/Qt-5/qsettings.html
However, you might need to take care of converting some of them back to values from QVariant.
Following code, dumps all ini sections and all keys and values.

  QSettings settings("e:/eds.ini", QSettings::IniFormat);
    const QStringList childGroups = settings.childGroups();
    foreach (const QString &group, childGroups) {
        settings.beginGroup(group);
        qDebug().noquote().nospace() << "|" << group << "|";
        const QStringList childKeys = settings.childKeys();
        foreach (const QString &childKey, childKeys)
            qDebug().noquote().nospace() << childKey << "=" << settings.value(childKey).toString();
        settings.endGroup();
    }

output:

@mrjj thank you for you response. My further goal is to expose all this data to a qml application that will allow me to configure my devices correctly. For know i'll try what you suggested.
