Project description

📌 Project Overview This project demonstrates how to build an EtherCAT Master using an STM32F407VET6 microcontroller and the WIZnet W5500 Ethernet controller. By integrating the SOEM (Simple Open EtherCAT Master) library, the system communicates directly with EtherCAT slaves using raw Ethernet packet transmission, enabling real-time industrial networking. 🔧 Key Components MCU: STM32F407VET6 Ethernet Chip: WIZnet W5500 Library: SOEM (Simple Open EtherCAT Master) Communication: Raw Ethernet frame transmission to EtherCAT slaves ⚙️ Implementation Details 1. Hardware Setup STM32F407VET6 MCU…
