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.

Exploring the IoT with Qt

In this chapter, we will be exploring how Qt works with the Internet of Things (IoT). We will start by to understand what the IoT is comprised of, and then we will look at some examples, using Qt.

The main topics we will cover are the following:

  • Examining the IoT and Qt
  • Retrieving the weather using a Web API
  • Reading the temperature sensor in Qt
  • Publishing our status using Message Queuing Telemetry Transport (MQTT)

As we continue to uncover new requirements for BigProject, you will learn the following:

  • How IoT came about and what you can use it for
  • How Qt can help you with IoT
  • How to use Qt to access online data using a web-based API
  • How to use the cross-platform Qt Sensor classes to read sensors in Qt
  • How to use Qt support for MQTT
