The SPI data pins on the newer ethernet shield is on the ICSP connector. Connect digital pin 10 on the Uno to digital 10 on the shield, but pins 11-13 on the Uno (or the ICSP pins on the Uno) must be connected to the appropriate pins on the ethernet shield ICSP connector.
Digital pins 11-13 on the shield are not connected to the w5100 or the SD.
Could you tell me more detail all the pins I should connect from UNO to the Ethernet Shield?
Because I do not get which ICSP pins I should take? I dont find any label "ICSP"...
Is there any Vcc and ground pin I should also connect?which ones?
