NOTE: Good news! You can use arduino IDE v1.7 from Arduino.org which has

"Ethernet 2" library, which works with this board. It means you don't have to

download any modded libraries. Thank for the Vladimir Akopyan comments.

Step 3: Pin Definitions

Note: These parts should be declared at the beginning of the sketch.

1. Define W5500 SPI “SS” pin and “Reset” Pin:

#define SS

10U

//D10----- SS

#define RST

11U

//D11----- Reset

2. Setup function

void setup() {

pinMode(SS, OUTPUT);

pinMode(RST, OUTPUT);

digitalWrite(SS, LOW);

digitalWrite(RST,HIGH);

//Reset

delay(200);

digitalWrite(RST,LOW);

delay(200);

digitalWrite(RST,HIGH);

delay(200);

//Wait W5500
