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++.

Measuring time intervals

Every embedded application interacting with peripheral hardware or responding to external events has to deal with timeouts and reaction times. To do this properly, developers need the ability to measure time intervals with sufficient precision.

The C++ Chrono library provides an std::chrono::duration templated class for handling durations of arbitrary span and precision. In this recipe, we will learn how to use this class to measure the time interval between two timestamps and check it against a reference duration.

How to do it...

Our application will measure the duration of simple console output and compare it to the previous values in the loop.
