Detailed Description

The QKnxDatapointType class is a base class for datapoint types with specific properties.

A datapoint type represents the data corresponding to a KNX device functionality. It describes the data, setting the rules about the format and values to be allowed, and it holds the bytes containing the data.

This data is used in the data part of the QKnxTpdu class. To retrieve the data of a datapoint type, call bytes().

There are two types of a QKnxDatapointType: QKnxFixedSizeDatapointType for fixed length datapoint types and QKnxVariableSizeDatapointType for variable length datapoint types.

A datapoint type is identified by its main number and a sub number. Each main number corresponds to a datapoint type with a particular structure. The sub numbers correspond to different interpretations or naming of this structure.

The Qt KNX module provides a class for each datapoint type with the main number less than 30 and sub number less than 100. All datapoint types with the same main number inherit from a datapoint type class representing the main number datapoint type characteristics.

Adding Datapoint Types

To implement a datapoint type described in the KNX documentation but not implemented in the Qt KNX module, one can create a class inheriting from QKnxFixedSizeDatapointType or QKnxVariableSizeDatapointType and register this new class using an instance of QKnxDatapointTypeFactory:

#include mynewdatapointtype.h

int main()
    int mainType = 65535;
    int subType = 100;
    int typeSize = 1; // size in bytes

    auto &factory = QKnxDatapointTypeFactory::instance() ;
    factory.registerType<MyNewDataPointType>(mainType, subType, typeSize);
