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.

Embedded Qt


A major target of the Qt framework next to desktop systems are embedded systems, specifically Embedded Linux, where there are a few different ways to use Q. The main point of embedded Qt is to optimize the software stock by allowing you to boot straight into a Qt-optimized environment, and by allowing for a variety of ways to render to the display.

Qt for Embedded Linux supports the following platform plugins for rendering:

Plugin

Description

EGLFS

Provides an interface to OpenGL ES or similar 3D rendering API. Usually, the default configuration for Embedded Linux. More details about EGL can be found at the following address: https://www.khronos.org/egl.

LinuxFB

Writes directly to the framebuffer via Linux's fbdev subsystem. Only software-rendered content is supported. As a result, on some setups the display performance is likely to be limited.

DirectFB

Directly writes to the graphic card's framebuffer using the DirectFB library.

Wayland

Uses the Wayland windowing system. This allows for...
