[wiznet.co.kr:8011/Admin_Roo … _DV_V180(0](https://www.wiznet.co.kr:8011/Admin_Root/UpLoad_Files/BoardFiles/W5100_DV_V180%280%29).zip
It is example code. There are tcp, udp loopback example code. Refer to it.

You need to select how to access to W5100: direct bus, indirect bus, or SPI.

And you can see W5100 initialization and setting in datasheet chapter 5. You can program step by step.
