1. I cant get my Nanode to get an IP address.
   I get ENC28J60 Version 7 when running the DHCP test, but th eethernet lights dont come on (although they do flash three times when I reset the Nanode).
   Any ideas ?

   • Did you remember to add “, 8″ when initialising the ethernet library?
     I forgot to do that at first and I think that’s what happened to me too…

     Instructions here: http://wiki.london.hackspace.org.uk/view/Nanode_Applications#Before_You_Start

     edit: actually, looks like that says “version 0″, not “version 7″.
     This code worked for me…

     delayRate = 200;
     }

     }

     // Output a ip address from buffer
     void printIP( uint8_t *buf ) {
     for( int i = 0; i < 4; i++ ) {
     Serial.print( buf[i], DEC );
     if( i<3 )

     }
     }

     void loop(){
digitalWrite( DHCPLED, HIGH);
delay(delayRate);

}


     I have since switched to using EtherCard instead of EtherShield, and that made things a fair bit easier.
