ENDA Embedded C Naming Convention Guide

In the world of embedded systems development, using consistent naming rules is super important for making your code easy to read, work with, and collaborate on. These naming rules help ensure that you give meaningful names to your modules, data types, functions, and variables. This makes it easier to create software for embedded systems that runs well and is reliable.

One thing to note is that these naming rules don't affect how fast your code runs, but they are absolutely essential for making your code understandable and easy to work with.

This document focuses specifically on naming rules and provides examples to show you how to use them. For the style of writing code, ENDA follows the Linux kernel coding standard, with a few small differences. You can find more details about that in the linked documentation below.

Exceptions to the Linux Kernel Coding Style

USB/IP Setup Guide

USB/IP allows you to share USB devices over IP networks, enabling remote access to devices as if they were connected locally. This guide outlines the setup process for both the server and client sides of USB/IP.

Server Setup

Install Linux Tools

To begin, you need to install the necessary Linux tools on your server. Use the following command:

Setting Up a Bridge Between Two Ethernet Interfaces

To create a network bridge between two Ethernet interfaces (eth0 and lan0) on a Linux system, you can use the following steps:

1. Open a terminal window.

2. Edit the /etc/network/interfaces file using a text editor with administrative privileges. For example, you can use sudo and nano:

sudo nano /etc/network/interfaces

  let points = {
