## Article

This video demonstrates a simple **Modbus TCP communication test** using an **STM32 microcontroller** and a **W5500 Ethernet chip**. The setup is configured with **STM32CubeMX** to enable SPI communication with the W5500, followed by porting and running lightweight application code to complete the Modbus TCP functionality.

The demonstration provides a clear example of integrating **STM32 + W5500**, configuring SPI via CubeMX, and implementing basic **industrial Ethernet communication**, making it useful for beginners exploring Modbus TCP and embedded networking.
