IoT: Getting started with cloud and modern IoT and IIoT from scratch

IoT and IIoT applications are special compared to other kinds of cloud applications as they have to deal with devices existing “outside” of data centers.

The following series of articles provide an end-to-end overview of what Microsoft Azure offers to handle some of the challenges involved in connecting an IoT Device with the Cloud.

By working through this series you will learn about the major concepts involved in getting your IoT/IIoT device connected to Microsoft Azure. In our examples we will feature Qt, Node.Js, Protobuf from Google and much more to get you started.

Using Shiboken2 to create Python bindings for a Qt library

With the release of Qt 5.12, Qt for Python is officially supported and can be used to write full-fledged Qt applications using Python as the main programming language.

This prompted us to also take a closer look at the bindings (the Python module is called PySide2) and also the underlying technology, namely the binding generator called Shiboken2.
