details

Analog inputs attached to pins A0 through A5

nstalling the library requires patching the current Ethernet library to add support for this chip:

1. Install W5200 library Download W5200 library,and find the Arduino library folder “(Arduino sketchbook folder)libraries”.If there is old version Ethernet library(W5100), please delete it. And unzip the new library to the folder, then restart your Arduino IDE.

2. Using the W5200 library and evaluate existing Ethernet example. In the Arduino IDE, go to Files->Examples->Ethernet and open any example, compile and upload the file to Arduino board.

3. Note: libraries/Ethernet/Ethernet.h needs the following at line 10 instead of #define MAX_SOCK_NUM 4, since it doesn’t #include “w5100.h” anymore.
