🌟 Introduction

This project demonstrates how to send and receive VLAN-tagged Ethernet frames using the W5500 Ethernet chip in MACRAW mode. The workflow involves:

• Sending and receiving Ethernet frames with VLAN tags.
• Analyzing network traffic with Wireshark.
• Capturing and reviewing hardware signals using an oscilloscope.

📂 Project Overview

The project includes the following materials:

Wireshark Capture Files:

• .png files for analyzing network traffic.
• Example file: data/vlan_test_capture.png.

Python Scripts:

• Scripts for generating data frames and controlling the W5500.
• Example script: ./py/vlan.py.

🛠️ Setup

Follow these steps to set up the project:

Install Python:

• Python 3.7 or later is required.
• Install the required packages:

pip install pyserial scapy

Install Wireshark:

• Download and install Wireshark from the official website.

🚀 How to Use

Run the Python Script:

• Generate VLAN-tagged frames and send them using the W5500:

python ./py/vlan.py

A VLAN packet Frame

Analyze with Wireshark:

• Open Wireshark and capture packets from your network interface.
• Apply a VLAN filter (0x8100) to isolate VLAN-tagged packets:
