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 on the Target

If you are expecting a really long and complex answer to How do I debug code running on the Target?, then you are going to be very disappointed. Qt Creator makes it incredibly easy. Are you ready?

To debug your code on the Target, simply make sure you have selected the Target build profile, then click the Debug icon () in the left toolbar.

Troubleshooting debugging

While developing this chapter, I ran into a small problem. I kept having issues with Qt Creator connecting to the debug program on the Target. After a few failed attempts, and a complete rebuild of my Target image for other reasons, I found the answer. The Yocto image we started with comes with a firewall installed. The firewall prevented...
