Hands-On Embedded Programming with Qt

By: 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.

Comparing the technologies

Now that we have looked at both technologies, let's compare them side by side:

Qt Widgets Qt Quick (QML)
Advantages
  • Mature technology
  • Very customizable
  • Fast
  • Easily interface to C/C++ libraries
  • Lower hardware (HW) requirements (don't need OpenGL, and so on)
  • Easy to learn
  • Based on ECMASCRIPT (JavaScript)
  • Easy to implement flashy GUI
  • Already contains support for modern UI concepts (flick scroll, slide in from side, and so on)
Disadvantages
  • Steep learning curve
  • Need to know how to use C++
  • Hard to implement flashy UIs because more custom coding is required
  • Cannot be used for WebGL interfaces
  • Not easy to interface to C/C++ libraries
  • Can be slower
  • Higher HW requirements (requires OpenGL, and so on)
Typical Applications
  • Desktop applications
  • Applications where large datasets must be viewed
  • Image capture and processing applications...
