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.

Appendix A: BigProject Requirements


In this chapter, we discovered even more requirements for our BigProject, and in the course of implementing them, we learned many new things. We started off by learning how Qt can access SQL databases. Then, we looked at how powerful and simple it is to work with state machines in Qt, especially when we can implement them by just drawing them! Next, we looked at adding a Virtual Keyboard to our project. Finally, we learned about Qt's WebSocket support and discussed cybersecurity in IoT devices.

Along the way, we also touched on other small topics, such as using Qt Style Sheets to control the color (styling) of elements in our GUI.

If you take the time to look at the completed solution in the Git repository, you will discover some other little jewels I have hidden in the code, including how to easily output the active states of a state machine, how to grab screenshots...
