Is there any kind of library that supports ethernet (W5500)?  
I want to receive cabled UDP and send it over 5Ghz wifi…  
Thanks in advance,  
Olivier

Hi @Olivier_Demoustier

There is no existing library support for W5500.  
But from its datasheet, it looks like it uses SPI to communicate, which should make it easy to port and use.

I’m not so an expert in programming. ☹
