STM32F429ZI fixed Ethernet with LWIP

[QuangIoT]

I hope this email finds you well. I am currently working with the STM32 NUCLEO F429ZI and encountering challenges with Ethernet connectivity. Specifically, I am looking for example projects demonstrating how to connect STM32 to Ethernet, both using a fixed IP and DHCP.

Hello @QuangIoT ,

You can refer to this example on GitHub.

In lwipopts.h file, there is this definition:

/* ---------- DHCP options ---------- */
#define LWIP_DHCP               1

1: DHCP activated,

0: deactivated -> Static IP.

In main.c for static IP:

/*Static IP ADDRESS*/
#define IP_ADDR0   ((uint8_t)192U)
#define IP_ADDR1   ((uint8_t)168U)
#define IP_ADDR2   ((uint8_t)0U)
#define IP_ADDR3   ((uint8_t)10U)

Hope it does answer your question.
