This example gives a basic overview of how one could use an FPGA in an embedded project. It uses the FPGA to sample an input and measure a voltage or similar, the way an oscilloscope would. The resulting ADC data is then sent over a serial link to a C++/Qt-based application, which displays the data.

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.
