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.

Technical requirements

The following hardware will be needed in order to derive the most from this chapter and the rest of this book:

  • A target device (Raspberry Pi 3B+) with supporting hardware. See the Embedded Hardware and Firmware Setup section for more information.
  • A host development PC running Ubuntu 16.04 or higher. This can be running directly on a PC or in a VM with network access. Other Linux distributions may work, but this book is written for Ubuntu. (I am running Ubuntu 18.10 on dedicated hardware.) You will need the following access rights for your account on the host:
    • Administrative (or root) privileges for installing software on your development PC are needed.
    • A web browser (Chrome is recommended) is required.
    • Internet access is necessary.
    • The following tools should be configured and working on the host:
      • ssh
      • rsync
      • scp
      • tar
      • xz
      • bzip2
      • g++
      • patch
    • The Host PC must be connected to a network that can also connect to the target device.
    • The Host PC must be able to read/write micro SD cards. You will want a fast SD card reader.

Additionally, this book assumes that you have at least a basic grasp of the following technologies:

  • Installation of distribution provided software packages on your development PC
  • A basic understanding of how to use Linux, including how to make files executable, run a program, edit a text file without a GUI, and safely reboot it
  • C++11 programming and debugging
