Connecting to the Internet using the W5500 powered Ethernet Shield
Arduino Ethernet Shield allows an Arduino board to connect to the internet. It can serve as either a server accepting incoming connections or a client making outgoing ones. The library supports up to four concurrent connection (incoming or outgoing or a combination).
For more details, please visit : Arduino Ethernet Library Page.
Before COMPILING THE SOFTWARE, Download and install Arduino 1.0.5 from the Arduino software page.
To use ioShiled-A(WIZ550io), you need to update new WIZnet Ethernet Library. Because ioShield-A use W5500 new chipset instead of W5100 which is used original Ethernet Shield.
The first step is to download the latest version of the Wiznet Ethernet Library from GitHub.
