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.

Usage scenarios


We don't want the infotainment system to be activated every single time that the voice user interface recognizes command words when they are not intended as such. The common way to prevent this from happening is by having a keyword that activates the command interface. If no command is recognized after the keyword within a certain amount of time, the system reverts to the keyword-spotting mode.

For this example project, we use the keyword computer. After the system spots this keyword, we can use the following commands:

Command

Result

Play Bluetooth

Starts playing from any connected A2DP source device (unimplemented).

Stop Bluetooth

Stops playing from any Bluetooth device.

Play local

Plays the (hardcoded) local music file.

Stop local

Stops playing the local music file, if currently playing.

Play remote

Plays from an online streaming service or server (unimplemented).

Stop remote

Stops playing, if active.

Record message

Records a message. Records until a number of seconds of silence occurs...
