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++.

Learning about message queue and publisher-subscriber models

Most of the IPC mechanisms provided by POSIX operating systems are quite basic. Their APIs are built using file descriptors and they treat input and output channels as raw sequences of bytes.

Applications, however, tend to use data fragments of specific lengths and purposes for data interchange messages. Despite API mechanisms of operating systems being flexible and generic, they are not always convenient for message exchange. That is why dedicated libraries and components were built on top of default IPC mechanisms to simplify the message exchange mode.

In this recipe, we will learn how to implement an asynchronous data exchange between two applications using the publisher-subscriber (pub-sub) model.

The model is easy to understand and widely used for the development of software systems designed as collections...
