Hi,
I have not tried the w5500 yet
I might order one at some point
most of the code should work though without any modification.
probably some changes in the ethernet library
I will investigate
meanwhile, you can try editing the lib
according to Arduino - Home
NB. You can reuse your code written for Arduino Ethernet Shield, simply replacing
#include <Ethernet.h> --> #include <Ethernet2.h>
#include <EthernetUdp.h> --> #include <EthernetUdp2.h>
