Connect Arduino to a network with HR911105A

Connect the Hanrun HR911105A network interface to an Arduino with the following method:

Arduino pin HR911105A pin
Arduino pin 12 SO (SPI MISO)
Arduino pin 11 SI (SPI MOSI)
Arduino pin 13 SCK (SPI SCK)
Arduino pin 10 CS (SPI SS)
Arduino 3v3 (or 5v) VCC
Arduino GND GND


Download the uIP library here:

Extract it and put it in the Arduino libraries folder.

In your sketch you can use any ethernet example.

Change #include <Ethernet.h> to #include <UIPEthernet.h> to use the proper library.
