Practical C Programming

By: B. M. Harwani

Overview of this book

Used in everything from microcontrollers to operating systems, C is a popular programming language among developers because of its flexibility and versatility. This book helps you get hands-on with various tasks, covering the fundamental as well as complex C programming concepts that are essential for making real-life applications. You’ll start with recipes for arrays, strings, user-defined functions, and pre-processing directives. Once you’re familiar with the basic features, you’ll gradually move on to learning pointers, file handling, concurrency, networking, and inter-process communication (IPC). The book then illustrates how to carry out searching and arrange data using different sorting techniques, before demonstrating the implementation of data structures such as stacks and queues. Later, you’ll learn interesting programming features such as using graphics for drawing and animation, and the application of general-purpose utilities. Finally, the book will take you through advanced concepts such as low-level programming, embedded software, IoT, and security in coding, as well as techniques for improving code performance. By the end of this book, you'll have a clear understanding of C programming, and have the skills you need to develop robust apps.

Embedded Software and IoT

When it comes to doing specific tasks more efficiently and precisely, embedded systems are preferred. They work as independent components, and they can be collectively combined into larger pieces of equipment. The internet is a vast and endless source of information; consequently, the Internet of Things (IoT) plays a major role in making embedded devices smarter so that they can be managed and controlled remotely.

In this chapter, we'll deep dive into the following recipes related to embedded software and IoT:

  • Toggling the port of a microcontroller in Embedded C (blinking LED)
  • Incrementing the value of a port in Embedded C
  • Toggling the voltage in an output pin using Arduino (blinking LED)
  • Taking input from the serial port using Arduino
  • Sensing the temperature using Arduino with the LM35 sensor
