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.

Platform-independent build systems


Ideally, the project and build system we choose could be used to build the target platform on any desktop platform. Usually, the main consideration here is the availability of the same toolchain and programmer for each development platform. Fortunately, for AVR- and ARM-based MCU platforms, the same GCC-based toolchain is available, so that we do not have to take different toolchains with different naming conventions, flags and settings into account.

The remaining challenge is simply to invoke the toolchain, and subsequently the programmer utility, in a way that doesn't require any knowledge of the underlying OS.

In Chapter 6, Testing OS-Based Applications, we looked at a multitarget build system, which could produce binaries for a wide variety of targets with minimal effort for each new target. For an MCU target, there would only be the following two targets:

  • The physical MCU target
  • The local OS target

Here, the first target is obviously fixed, as we picked...
