W5500 interface with Atsamd21g18a


I am working on Atsamd21g18a using atmel studio, and I want to interface w5500 ethernet chip with Atsamd21g18a, ultimately I want to send data from Atsamd21g18a to ethernet using w5500 in atmel studio, anybody can help me how to do this?



You can just connect to as below picture.
W5500 SPI Frame is refer to datasheet P.14

then what are the next steps…?
what is the code (without library)?

The ioLibrary means “Internet Offload Library” for WIZnet chip. It includes drivers and application protocols. The driver (ioLibrary) can be used for the application design of WIZnet TCP/IP chips as W5500, W5300, W5200, W5100 W5100S.

You need to modify the value of WIZCHIP in wizchip_conf.h

#define _WIZCHIP_                      W5500   // W5100, W5100S, W5200, W5300, W5500

You can use the ioLibrary as W5500 .
