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.

8-bit means 8 bits


Not surprisingly, the use of 16-bit and 32-bit integers on 8-bit MCUs is pretty slow. This is because the system has to perform multiple operations on the same integer value, as it can only fit 8 bits into its registers at a time.

Similarly, the use of floating-point variables on a system without a floating-point unit (FPU) means that such operations are highly suitable for slowing a system down to a crawl as the integer-only processor struggles to keep up with a flow of instructions aimed at simulating floating-point operations.
