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.

Toggling the port of a microcontroller in Embedded C (blinking LED)

In this recipe, we will learn how to send HIGH and LOW signals to a specific port that is connected to an LED, and make the LED blink. The idea behind this exercise is to learn how to control a device that is connected to a specific port of the microcontroller. 

How to do it…

To toggle the port of a microcontroller in Embedded C, perform the following steps:

  1. We will carry out this recipe using Keil; double-click on the Keil uVision5 icon to activate the IDE.
  2. Create a new project by clicking on the Project | New uVision Project option.
  3. When prompted, specify the project name and the folder where you want to create the new project...
