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++.

Converting the endianness

While serialization libraries deal with the endianness under the hood, there are situations where developers might want to implement a lightweight communication protocol themselves. 

While the C++ Standard Library does not provide functions for serialization, developers may utilize the fact that, in binary network protocols, byte order is defined and is always big-endian.

The Standard Library provides a set of functions that can be used for conversion between the current platform (hardware) and big-endian (network) byte orders:

  • uint32_t htonl (uint32_t value): Converts uint32_t from hardware to network order
  • uint32_t ntohl (uint32_t value): Converts uint32_t from network to hardware order
  • uint16_t htons (uint16_t value): Converts uint16_t from hardware to network order 
  • uint16_t ntohl (uint16_t value): Converts...
