As advertise the W5500 have Embedded MAC , but I can't find anywhere how to retrieve that information.

Product : W5500 Ethernet with POE Control Board(Arduino Compatible)
I use the that library : https://github.com/Wiznet/WIZ_Ethernet_Library

Hi Hakim? ,

Welcome!

As you could found in the code setting part, the mac address is a address which you could write, the embedded one is the 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED indeed. you can modify it if it's conflict with your other devices. Actually, all W5500,5100 device not for bussiness purpose would not occupy a real mac address.

Code: Select all

// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192, 168, 1, 177);

Btw, thanks for your asking, we will add it in the FAQ part on the wiki.
