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.

Configuring Qt Creator for our Target

Back when I started cross-compiling Qt for embedded QNX devices, Qt Creator was just starting to offer limited support for handing remote Targets. Fortunately for us, a lot of work was put into Qt Creator to make it very easy to implement cross-compilation, remote running, and remote debugging.

The following sections walk you through the process of setting up Qt Creator. These same basic steps can be applied for any supported Targets. The order of the steps is important, as some steps require the previous steps to have been completed first:

  1. Tell Qt Creator about the device
  2. Tell Qt Creator about the cross-compiler toolchain
  3. Configure the debugger for the device
  4. Tell Qt Creator about the Qt build for the device
  5. Create a Qt Kit with the preceding information

Each step has its own section.

All settings are done through the Options dialog. You...
