Project description

📎 Introduction This project demonstrates how to port the WIZnet W5500 Ethernet controller to an STM32 MCU using SPI, and implements a full set of features including: DHCP and static IP configuration TCP Server / Client communication UDP data transmission Embedded HTTP Web Server (controlling a GPIO-LED via browser) The project uses the WIZnet official ioLibrary and is suitable for embedded developers looking to learn real-world network stack implementation with W5500. 🔧 Hardware & Software Used MCU: STM32F407 series Ethernet Chip: WIZnet W5500 IDE: STM32CubeMX + Keil MDK5 / STM32 HAL…
