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.

Debugging Qt applications

Debugging is part of code development, so let's explore some ways we can debug our applications.

Old school is a term that seems to follow me. It started in some online video games where new players would say, "He's cool. He plays old school." Now, it even adorns the 1988 car I bought as a project. The previous owner put it on, but I sort of like it.

I say that because we will be looking at old-school debugging methods that are still applicable today; then, we will look at how to use the modern debugging interface that is integrated in Qt Creator.

Old-school debugging

I wrote my first program in 1983. It was an MS-BASIC program running under CPM to help me manage a newspaper delivery...
