ioShield-A

Overview

ioShield-A allows an Arduino board to connect to the Internet.

It is based on the WIZ550io network module which uses WIZnet W5500 ethernet chip (W5500 Datasheet). The WIZnet W5500 provides a network (TCP/IP) stack capable of both TCP and UDP. It supports up to eight simultaneous socket connections. And, when Powered on and nRESET triggered, WIZ550io initializes itself with embedded real MAC and default IP address and can be pinged from user’s computer.

As ioShield uses W5500 chipset, instead of W5100 which was used before in the Arduino Ethernet Shield, users needs to use WIZnet Ethernet Library.

Available Board List

Arduino Board
- Arduino board (e.g. the Uno)
- Arduino Leonardo
Arduino-compatible Board
- Seeeduino v3.0 : Based on Arduino Duemilanove

Although you have non-AVR Arduino-compatible board, you could use ioShield Hardware. But you should use adequate S/W libraries for each chipsets. please refer to each product's web site.

Network Connections

Connect the shield to your computer or a network hub or router using a standard ethernet cable (CAT5 or CAT6 with RJ45 connectors). Connecting to a computer may require the use of a cross-over cable (although many computers, including all recent Macs can do the cross-over internally).

Using WIZnet Ethernet Library for ioShield-A

Connecting to the Internet using the W5500 powered Ethernet Shield

Change code
Examples

Arduino Ethernet Library

from : http://arduino.cc/en/Reference/Ethernet

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.

Note: Certain functions may not work in earlier versions. Before using this library, please update the latest verison of Arduino Software.
See the Getting Started with Arduino.
See the foundations page from Arduino for in-depth description of core concepts of the Arduino hardware and software
See the hacking page from Arduino for information on extending and modifying the Arduino hardware and software
See the Links page from Arduino, Playground page from Arduino for other documentation.

Update Ethernet Library

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.

How to update the Ethernet library.

Open the archive and extract the file “WIZ_Ether_Library.zip” to a convenient spot (I use the Desktop).
Put(Overwrite) the “Ethernet” folder in this library to the libraries folder in the Arduino Installation Folder (for example, normaly you can find Arduino libraries folder as “C:\Program Files\Arduino\libraries\”.), ~~or select “Sketch → Import Library… → Add Library…” in Aruino IDE, and select the folder loacation. and then, you can see the new directory in your “My Document/Arduino/libraries/”.~~

Change code depending WIZnet chip, W5100, W5200 or W5500

Select the define variable in “Ethernet/utility/W5100.h”. When you use WIZ550io, ioShield-Series, you uncomment “#define W5500_ETHERNET_SHIELD”.

w5100.h

#ifndef	W5100_H_INCLUDED
#define	W5100_H_INCLUDED
 
#include <avr/pgmspace.h>
#include <SPI.h>
 
typedef uint8_t SOCKET;
 
//#define W5100_ETHERNET_SHIELD // original ethernet shield from Arduino
//#define W5200_ETHERNET_SHIELD // Ethernet Shield version 2 from Seeed.
#define W5500_ETHERNET_SHIELD  // ioShield Series

Examples

Now you are ready to go to “File → Example → Ethernet”, and select examples what you want. There are many simple examples in Ethernet Library Folder as like

Test Twitter: A Twitter Simple Posting or refer http://playground.arduino.cc/Code/TwitterLibrary
Test HTTP Client(WebClient): A Simple HTTP Client test

Basically, you can refer the usage for each examples in Arduino site.

http://arduino.cc/en/Tutorial/ChatServer: set up a simple chat server.
http://arduino.cc/en/Tutorial/WebClient: make a HTTP request.
http://arduino.cc/en/Tutorial/WebClientRepeating: Make repeated HTTP requests.
http://arduino.cc/en/Tutorial/WebServer: host a simple HTML page that displays analog sensor values.
XivelyClient: connect to ~~pachube.com~~ xively.com, a free datalogging site. not a big change except service name.
XivelyClientString: send strings to ~~pachube.com~~ xively.com. not a big change except service name.
http://arduino.cc/en/Tutorial/BarometricPressureWebServer: outputs the values from a barometric pressure sensor as a web page.
http://arduino.cc/en/Tutorial/UDPSendReceiveString: Send and receive text strings via UDP.
http://arduino.cc/en/Tutorial/UdpNtpClient: Query a Network Time Protocol (NTP) server using UDP.
http://arduino.cc/en/Tutorial/DnsWebClient: DNS and DHCP-based Web client.

Twitter Test

Before Compile

Before tweeting, get a token at http://arduino-tweet.appspot.com/ . This library send a tweet via the site to avoid using up the memory of Arduino by complex OAuth signature stuff.
Then you can get the token-code.
Update new “Ethernet” library for ioShield. please refer Update Ethernet Library
You can see an example sketch from “File → Examples → Ethernet → Twitter_SimplePost”.
Done~~.
original source from http://playground.arduino.cc/Code/TwitterLibrary

Change code & Compile

You need to create an instance of Twitter class like below:

in Twitter_SimplePost.ino..

Twitter_SimplePost.ino

// If you don't specify the IP address, DHCP is used(only in Arduino 1.0 or later).
// fill in an available IP address on your network here,
IPAddress ip(1,1,1,1);
IPAddress gw(1,1,1,1);
IPAddress snip(1,1,1,1);
IPAddress dnsip(1,1,1,1);
 
// Your Token to Tweet (get it from http://arduino-tweet.appspot.com/)
Twitter twitter("YOUR-TOKEN-HERE"); // this was YourID:Password in 1.0.1

You need also to refer begin Ethernet library.

please refer the below image to change code.

and compile, upload code on your Arduino Board.
