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 the FlatBuffers library

Serialization and deserialization is a complex topic. While ad hoc serialization may look simple and straightforward, it is difficult to make it generic, easy to use, and fast. Thankfully, there are libraries that handle all of these complexities.

In this recipe, we will learn how to use one of the serialization libraries: FlatBuffers. It was designed with embedded programming in mind, making serialization and deserialization memory efficient and fast.

FlatBuffers uses an Interface Definition Language (IDL) to define a data schema. The schema describes all the fields of data structures that we need to serialize. When the schema is designed, we use a special tool called flatc to generate the code for a particular programming language, which is C++ in our case.

The generated code stores all data in serialized form and provides developers with so...
