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.

In this chapter, we learned how to set up a Raspberry Pi 3B+ for embedded Qt development. We also learned how to prepare a Linux host PC for cross compilation for the Raspberry Pi Target. We explored how to pull the parts of the root filesystem that are needed for development from the Target. Together, we also learned how to configure and build Qt from its source code and then push the updated root filesystem to the Target.

While we have only dealt with one particular Target, working with applications for other target systems is fairly straightforward. The differences will be in what initial target image you select, the cross compiling tool chain, and the way Qt is configured. Hopefully, by working through this chapter, you will be confident enough to be able to do it for any system you find.

In Chapter 2, Writing Your First Qt Application, we will write our first Qt program using Qt Widgets, test it on the host, and find out just how easy it is to find and fix a bug using Qt Creator.
