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.

Running a quick test to ensure how the program works

If you've made it this far, your Qt for IoT Development environment and hardware should all be ready to go. Let's run a quick test to make sure this is the case. I've written a short test program to verify the basic setup of the Raspberry Pi itself. It can be found in the Git repository for this book. Download the single executable, C01_01-ItWorks, to ~/raspi. Transfer it to the device and then execute it. Then, follow these steps:

  1. On the host PC, enter the following command:
[On Host] $ scp ~/raspi/C01_01-ItWorks root@raspberrypi:/home/root
  1. Then, ssh into the Raspberry Pi and start it:
[On Target] $ /root/C01_01-ItWorks
  1. You should now see a picture with the words It Works! on the display. If not, verify your installation steps:

You can hit Ctrl+C in the ssh connection to terminate the program.
