Abstract

In the paper,a system based on STM32 hardware platform for Ethernet communication technology is designed.The system makes full use of the features of the FreeRTOS real-time operating system and the LwIP protocol stack.The Ethernet controller LAN8720A and the RJ45 interface are used to connect to the Ethernet,and the UDP protocol communication process is extended on the basis of the NETCONN interface of the LwIP protocol stack,which allows bi-directional packet transmission between the host computer and the client.

Key words

LwIP / FreeRTOS / STM32 / Ethernet communication / UDP / LAN8720A
