Overview of this book

Developing applications for embedded systems may seem like a daunting task as developers face challenges related to limited memory, high power consumption, and maintaining real-time responses. This book is a collection of practical examples to explain how to develop applications for embedded boards and overcome the challenges that you may encounter while developing. The book will start with an introduction to embedded systems and how to set up the development environment. By teaching you to build your first embedded application, the book will help you progress from the basics to more complex concepts, such as debugging, logging, and profiling. Moving ahead, you will learn how to use specialized memory and custom allocators. From here, you will delve into recipes that will teach you how to work with the C++ memory model, atomic variables, and synchronization. The book will then take you through recipes on inter-process communication, data serialization, and timers. Finally, you will cover topics such as error handling and guidelines for real-time systems and safety-critical systems. By the end of this book, you will have become proficient in building robust and secure embedded applications with C++.

For a long time, development for embedded systems required either plain C or assembly language. There was a host of good reasons for this. The hardware did not have enough resources to run applications written in higher-level programming languages, such as C++, Java, or Python, but more importantly, there was no real need to write software in these languages. Limited hardware resources put a limit on software complexity, the functionality of embedded applications remained relatively simple, and the capabilities of C were sufficient to implement it.

As a result of the progress in hardware development, more and more embedded systems nowadays are powered by inexpensive yet powerful System-on-Chip capable of running a general-purpose multitasking operating system such as Linux.

Growing hardware capabilities demand more complex software, and more and more often C++ becomes the language of choice for new embedded systems. With its you don't pay for what you don't use approach it allows developers to create applications that use computational and memory resources, like applications written in C, but gives developers many more tools for dealing with complexity and safer resource management, such as object-oriented programming and the RAII idiom.

Seasoned embedded developers with substantial experience in C often tend to write code in C++ in a similar, habitual way, considering this language just as an object-oriented extension of C, a C with classes. Modern C++, however, has its own best practices and concepts that, properly used, help developers avoid common pitfalls and allow them to do a lot in a few lines of code.

On the other side, developers with C++ experience entering the world of embedded systems should be aware of the requirements, limitations, and capabilities of specific hardware platforms and application domains and design their C++ code accordingly.

The goal of this book is to bridge this gap and demonstrate how features and best practices of modern C++ can be applied in the context of embedded systems.
