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++.

Exploring real-time operating systems

As has already been discussed in this chapter, Linux is not a real-time system. It is a good choice for soft real-time tasks, but despite the fact that it provides a real-time scheduler, its kernel is too complex to guarantee the level of determinism needed for hard real-time applications.

Time-critical applications require either a real-time operating system to run, or are designed and implemented to run on bare metal, with no operating system at all.

Real-time operating systems are usually much simpler than general-purpose operating systems such as Linux. Also, they require tailoring to the particular hardware platform, usually a microcontroller.

There are a number of real-time operating systems, with most of them being proprietary and not free. FreeRTOS is a good starting point to explore the capabilities of real-time operating systems...
