C Tutorials Overview

Introduction

In this tutorial series, you will be reviewing C by studying the topic linked to the given examples. This is a self-study guide designed to let the audience work on examples and guide them on what they need to learn. Each topic will have examples with comments. On each example code, you might need to change or add some lines to complete the code. Since this is just a review, you won't be using yet a cross-compiler. You will need a cross-compiler if you will be building for a different architecture. But, the concept will be the same.

Objectives

In this overview, you will be able to:

  • Install basic C programming tools
  • Review the C programming language

Preparations

You will need to install the following tools to be able to follow the examples:

  1. Text Editor - Visual studio code is highly recommend. But, you may use your preferred editor.
  2. Terminal - To avoid dependence on specific IDE and to give you a better understanding on build automation, we will be using a terminal for command line interface-based building.
  3. Compiler - You will be needing a compiler to build codes in C into binaries. We will be using GCC. If you think that devcpp or Code-blocks is a compiler, read the difference of a compiler and an IDE.
  4. build tools - You will need to install "make".

Installation

Windows

  1. Install your text editor. If you will be using Visual studio code, download and install this. Select the approapriate installer (i.e. Use x64-bit installer for 64-bit machines).

  2. On windows, you already have a built in terminal. But you can install other terminals. For this tutorial, we will just use powershell.

  3. Compiler. As much as possible, we won't be using third-party libraries in this tutorial. So, MinGW GCC is enough. You can download MinGW here.Select the mingw-get-setup.exe.

    This installer will install the toolchain you need to build C applications. Double-double click the installer and follow the installer's instruction until you reach the Installation Manager. Select the basic setup and click the mingw32-base-bin as show in the figure below. mingw32-base-bin To apply the the changes in the packages, from the Menu in the top left corder, click Installation->Apply Changes. This will download the tools.

    To check if the compiler is in installed, open a powershell window and type the following:

    gcc --version

    This should return the version of compiler. For example:

    PS D:\> gcc --version
gcc.exe (x86_64-posix-seh-rev0, Built by MinGW-W64 project) 8.1.0

  4. You might already have make from the mingw32 installation. You can try running from powershell the following.

    make --version

    This should return the version of your make like this:

    PS C:\> make --version
GNU Make 3.81

PARTICULAR PURPOSE.

  5. In case Steps 3 or 4 does not return the mingw versions, manually add the bin folder into your machine's Environment Variables. Afterwhich, recheck the mingw versions done in the previous steps to verify your installation is successful.

environment_variables

That's it! You are now ready to start the C tutorial.

Accessing the Tutorials

Each topic is inside a folder in this format N_topic, where N is the number of the tutorial and topic is the topic covered by the tutorial. When accessing each tutorial, read the instructions in the README files in the folder.

There are two ways to open the source codes.

Option 1: From the explorer window

You can navigate to this c_overview folder via the explorer windows, right-click in any empty area, and select Open with Code as shown in the image below. vscode_explorer

This will open Visual studio code and treat the folder as your project folder. Which will show the other files and folders of this below this folder as shown in the figure below. vscode_folder

Option 2: From the powershell

You can navigate to the c_overview folder using the cd command. For example, assuming you are currently in the C:\mcu_tuts\ folder, run the following command

PS D:\mcu_tuts> cd .\tutorials\c_overview\

You will then be inside the c_overviews folder as shown below.

PS D:\mcu_tuts\tutorials\c_overview>

Run Visual Studio code by running code . as shown in the figure below.

PS D:\mcu_tuts\tutorials\c_overview> code .
