Hands-On Embedded Programming with QT

By: John Werner

Overview of this book

Qt is an open source toolkit suitable for cross-platform and embedded application development. This book uses inductive teaching to help you learn how to create applications for embedded and Internet of Things (IoT) devices with Qt 5. You’ll start by learning to develop your very first application with Qt. Next, you’ll build on the first application by understanding new concepts through hands-on projects and written text. Each project will introduce new features that will help you transform your basic first project into a connected IoT application running on embedded hardware. In addition to gaining practical experience in developing an embedded Qt project, you will also gain valuable insights into best practices for Qt development and explore advanced techniques for testing, debugging, and monitoring the performance of Qt applications. The examples and projects covered throughout the book can be run both locally and on an embedded platform. By the end of this book, you will have the skills you need to use Qt 5 to confidently develop modern embedded applications.

Summary

As we have worked through this chapter, we have built out our BigProject and learned a few things on the way.

First, we took a quick look at the history of IoT and where Qt fits into that. Then, we started transforming BigProject into an IoT device—not a small point device, but an IoT controller. As part of that transformation, we learned how to access web services from within Qt so that we could retrieve weather conditions.

We then learned how to use QSensor to access sensors in our system. In this particular case, it was the temperature sensor on the Sense HAT.

Finally, we took a look at a couple of IoT and automation protocols that are available in Qt and transformed BigProject from a simple display-controller to an MQTT client that publishes updates.

In Chapter 10, Using More Qt-Related Technologies, we will explore a few more Qt-related technologies, including...
