Overview of this book

C++ is a great choice for embedded development, most notably, because it does not add any bloat, extends maintainability, and offers many advantages over different programming languages. Hands-On Embedded Programming with C++17 will show you how C++ can be used to build robust and concurrent systems that leverage the available hardware resources. Starting with a primer on embedded programming and the latest features of C++17, the book takes you through various facets of good programming. You’ll learn how to use the concurrency, memory management, and functional programming features of C++ to build embedded systems. You will understand how to integrate your systems with external peripherals and efficient ways of working with drivers. This book will also guide you in testing and optimizing code for better performance and implementing useful design patterns. As an additional benefit, you will see how to work with Qt, the popular GUI library used for building embedded systems. By the end of the book, you will have gained the confidence to use C++ for embedded programming.

3D designer

With Qt 5, the Qt 3D module was introduced, which streamlined access to the OpenGL rendering API. This new module was used as the foundation for the Qt 3D Designer editor and the accompanying runtime. It can be used to create highly dynamic GUIs, featuring a combination of 2D and 3D elements.

It is quite similar to hand-crafted QML-based GUIs, but provides a more streamlined workflow, ease of adding animations, and previewing the project. It's similar to the Qt Designer Studio, which focuses more on 2D GUIs, but this one is not available for free, instead requiring you to purchase a license.
