This is the Interface library for WIZnet W5500 chip which forked of EthernetInterfaceW5500, WIZnetInterface and WIZ550ioInterface. This library has simple name as "W5500Interface". and can be used for Wiz550io users also.

Last commit 28 Apr 2015 by W5500-Ethernet-Interface Makers

This Library for W5500 users. no need to use lwIP(or S/W TCP/IP) Some update & code clean for W5500 only refer from WIZ550ioInterface, WIZnetLibrary and WiflyInterface.

Thanks for ban4jp. This library forks of WIZ550ioInterface.
