# eth_w5500_v0.3_test

> This project provides an example of setting up and testing a network connection using an ESP32 board and a W5500 Ethernet module.

Original author: Ruslan Nadyrshin (source: https://github.com/rnadyrshin/eth_w5500_v0.3_test)

## Components

- **Espressif ESP32S** x 1 ([docs](https://www.espressif.com/en/products/socs/esp32))
- **WIZnet W5500** x 1 ([docs](https://docs.wiznet.io/Product/Chip/Ethernet/W5500))

WIZnet parts: W5500 ([Datasheet](https://docs.wiznet.io/Product/Chip/Ethernet/W5500/datasheet?utm_source=maker&utm_medium=project&utm_campaign=w5500), [product hub](https://maker.wiznet.io/products/w5500/))

## Article

### **Overview**

This example shows how to use the Ethernet driver with **esp_netif**. The Ethernet driver initialization is separated into its own component to make it clear. The process is as follows:

1. Install the Ethernet driver.

2. Attach the driver to **esp_netif**.

3. Send DHCP requests and wait for an IP address.

4. Once an IP address is obtained, you can ping the device.

Use this example as a template for creating new Ethernet applications, such as connecting to an IoT cloud, and then add your own code.

### **Hardware Required**

To run this example, it's recommended to use the official ESP32 Ethernet development board - ESP32-Ethernet-Kit. It can also work with third-party ESP32 boards that have a compatible Ethernet PHY chip. Supported PHY chips include LAN8720, IP101, DP83848, and RTL8201; additional drivers must be user-implemented.

The **esp_eth** component can drive third-party Ethernet modules with integrated MAC and PHY, using common interfaces like SPI or USB. This example uses DM9051, W5500, or KSZ8851SNL SPI modules to show driver installation.

ESP-IDF supports multiple Ethernet interfaces. Possible combinations include:

- Internal EMAC with one SPI Ethernet module.

- Two identical SPI Ethernet modules on one SPI interface with different CS.

- Internal EMAC with two SPI Ethernet modules.

### **Pin Assignment**

For two Ethernet SPI modules on a single SPI interface, data (MOSI/MISO) and CLK signals are shared, but CS, interrupt, and reset pins must connect to separate GPIOs for each module.
