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++.

Communication with peripheral devices is an essential part of any embedded application. Applications need to check the availability and status and send data to and receive data from a variety of devices. 

Each target platform is different and many ways of connecting peripheral devices to the computing unit exist. There are, however, several hardware and software interfaces that have become industry standard for communication with peripheral devices. In this chapter, we will learn how to work with peripheral devices connected directly to processor pins or over serial interfaces. This chapter covers the following topics:

  • Controlling devices connected via GPIO 
  • Exploring pulse-width modulation
  • Using ioctl to access a real-time clock in Linux
  • Using libgpiod to control GPIO pins
  • Controlling I2C peripheral devices

The recipes in this chapter involve interaction...
