Hi,

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?

Thanks

Regards,

ok,
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 .

Hello,
I have encountered an issue with the W5500 ethernet IC. During our environmental testing, we subjected our product to a temperature of -40°C for 4 hours. Afterward, we noticed that the W5500 is not functioning properly. I have two questions regarding this situation:

  1. What could be the reason behind this problem occurring?
  2. Could you please provide guidance on how to resolve this issue?

Please create new thread for your issue. No idea on the reasons - you need to explain what “is not functioning properly” means in more detail. The cause can be any component involved, for example crystal oscillator.
