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.

Example – basic media player


Another basic example of an SBC-based embedded system is a media player. This can involve both audio and audio-visual (AV) media formats. The difference between an SBC-based system being used to play back media with regular keyboard and mouse input, and an embedded SBC-based media player, is that in the latter's case the system can only ever be used for that purpose, with the software and user interface (physical- and software-wise) both optimized for media player use.

To this end, a software-based frontend has to be developed, along with a physical interface peripheral, using which the media player can be controlled. This could be something as simple as a series of switches connected to the GPIO pins, with a regular HDMI display for output. Alternatively, one could use a touch screen, although this would require a more complex driver setup.

Since our media player system stores media files locally, we want to use an SBC that supports external storage beyond the...
