In this tutorial, we’ll walk you through the process of creating a pseudo character driver in Linux.<\/span><\/p>\n

Setting up the Project Structure<\/strong><\/span><\/span><\/p>\n

Navigate to your custom drivers folder and create a new folder named “002pseudo_char_driver”. Inside this folder, create a file named “main.c.” Here we are going to implement the code. And also, let’s copy the makefile from the previous project. 001hello_world\/Makefile.<\/span><\/span><\/p>\n

You can refer to Figure 1 for the directory structure.<\/span><\/p>\n
