Control your Buderus Logamatic 2107 or HS-2105 with MQTT or Home Assistant

Ethernet Example for RP2040

WIZnet TCP/IP chips (such as W5500/W5100..) SAL framework implement.

Example of using SPI Ethernet module with esp8266

A tool for network scanning and ARP spoofing using the Atmega32u4 and W5500

Embedded rust support for the Wiznet W5500 SPI internet offload chip

Simple Ethernet WebServer, HTTP/HTTPS Client wrapper library for ESP32 boards using W5500 with LwIP Ethernet library. The WebServer supports HTTP(S) GET and POST requests, provides argument parsing, handles one client at a time. It provides HTTP(S), MQTT(S) Client and supports WebServer serving from LittleFS/SPIFFS

Connecting ESP32 to W5500 using micropython

RTOS-based binding for W5500 and LwIp

an IoT Edge device equipped with ESP32, DHT22, and Ethernet W5500

This is HTTPS/HTTP Server Library for ESP32, WT32_ETH01, ESP32 + LwIP W5500, ESP32 + LwIP W6100, ESP32 + LwIP ENC28J60. In the future, this library will support powerful-enough boards using LwIP WiFi/Ethernet, such as ESP8266, Portenta_H7, RP2040W, Teensy 4.1, etc.

Ethernet Example for RP2040, RP2350
