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++.

Using exceptions for error handling

While the error codes remain the most widespread technique of error handling in embedded programming, C++ offers another mechanism for this purpose, called exceptions.

Exceptions aim to simplify error handling and make it more reliable. When using error codes, developers have to check the result of each function for errors and propagate the result to the calling functions. This clutters the code with lots of if-else constructs, making the function logic more obscure.

When using exceptions, developers do not need to check for errors after every function invocation. Exceptions propagate through the call stack automatically, until they reach the code that can handle it properly by logging, retrying, or terminating the application.

While exceptions are the default error handling mechanism of the C++ standard library, communicating with peripheral...
