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.

Questions

  1. Is the IoT a new thing or a new name for something that has been around for almost two decades?
  2. Can Qt be used without a GUI?
  3. When accessing a web API, is the result returned synchronously or asynchronously?
  4. How should asynchronous results be handled?
  1. What does auto mean in C++11 (and later) versions of C++? Why would you use auto?
  2. What issues could occur if separate power supplies were to be used for the Raspberry Pi and Touchscreen driver board and panel?
  3. Qt is described as cross-platform. How does it handle getting information from sensors on different platforms and operating systems?
  4. What IoT protocols have been implemented for Qt?
  5. What general steps would you take to add the reporting of humidity and pressure published status from BigProject?
  6. What would you change in MainWindow if you wanted to publish status updates only every 5 minutes instead of every second...
