Fork of WIZ550ioInterface by ban4jp -

please get the new Library for WIZ550io, W5500 (WIZnet) http://mbed.org/teams/EthernetInterfaceW5500-makers/code/W5500Interface/

Import libraryW5500Interface

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.
