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.

Incrementing the value of a port in Embedded C

In this recipe, we will learn how to display values from 0 to 255 on a specific port of a microcontroller and make the value increment like a counter.

How to do it…

To increment the value of a port in Embedded C, perform the following steps:

  1. Launch the Keil uVision5 IDE.
  2. Create a new project by clicking on the New Project | New uVision Project option.
  3. Specify the project name and folder location when prompted. Let's give the new project the name CounterApp; click on Save.
  4. The device selection window will open and you will be prompted to select a device. From the Device combo box, select Legacy Device Database [no RTE].
  5. You will get the list of...
