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.

Building for the Target

Once we have configured a kit for our Qt build for the Raspberry Pi, we can start building Qt applications for the Target. You have already created one Qt application, and you have been told that it is very easy to rebuild a Qt application for different devices. Why don't we prove that? We will start by rebuilding HelloFromQt for the Target.

Open the HelloFromQt project if it is not already open.

Adding a kit to the project

The Projects page in Qt Creator allows us to configure a project, including adding a new kit to be built. You can access the Projects page by clicking the Projects icon () in the left icon bar:

Adding the Raspi kit is very straightforward:

  1. Right-click on Raspi under Build...
