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++.

Debugging microcontroller code

Compared with more powerful embedded platforms, such as the Raspberry PI, the debugging capabilities of Arduino are limited. The Arduino IDE does not provide an integrated debugger, and the Arduino board itself does not have a built-in screen. It does, however, have UART, and provides a serial interface that can be used for debugging purposes.

In this recipe, we will learn how to use the Arduino serial interface for debugging and reading user input.

How to do it...

We will implement a simple program for the Arduino controller that waits for user input on the serial port and turns the built-in LED on or off depending on the data:

  1. Open Arduino IDE and select New in its File menu. A new Sketch...
