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 condition variables

We learned how to synchronize simultaneous access to the same variable from two or more threads. The particular order in which threads accessed the variable was not important; we only prevented simultaneous reads and writes to the variable.

A thread waiting for another thread to start processing data is a common scenario. In this case, the second thread should be notified by the first thread when the data is available. It can be done using condition variables, supported by C++, starting from the C++11 standard.

In this recipe, we will learn how to use condition variables to activate data processing in a separate thread as soon as the data is available.
