Old Driver
W5100, W5200 and W5500 for WIZnet chipsets,
Import libraryWIZnet_Library
This is WIZnet Ethernet Interface using Hardware TCP/IP chip, W5500, W5200 and W5100. One of them can be selected by enabling it in wiznet.h.
if you want to use only W5500 or WIZ550io, you could use library as follows
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.
