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.

Microcontrollers in embedded super PCs

Depending on who you ask, embedded software runs on the following:

  • A 4-bit microcontroller surrounded by some custom logic and no OS
  • An Atom-based PC-104-sized card buried in the bowels of a machine with a real-time OS
  • A network of small, custom boards controlling everything in an automobile, including the brakes, engine, transmission, infotainment system, AC and heating, headlights, wipers, radio, and navigation software
  • A 64-bit, multicore AMD Ryzen monster with a GPU that makes a hardcore gamer jealous and costs more than the PC motherboard it is running on

Over the course of my career, I have worked on systems at both ends of the spectrum, and at several places in-between. All of these have qualified as an embedded system running embedded software.

Some embedded systems have no OS, while others may have full blown OSes, such as Windows...
