Hello,
I have been trying to implement the Rev3 Ethernet Shield with an Arduino Micro and I have some questions about the pins.
Here it says D2 is optional(?) does that mean I don't need to connect D2 from the Micro to D2 on the shield? I am already using D2 on the Micro for SDA so if I did need to use D2 would there be a way of changing it in the code to another pin?
Would running the UDPSendReceiveString work without D2?
I don't have either the ethernet shield or micro right now, I am just trying to prepare. I have already order the Micro so that cannot change but if there are any other Ethernet boards I am open to recommendations.
Thank you for your help,
Tyler
No help?
Well I have received my ethernet shield and arduino micro. The shield works perfectly with my uno but when I try using the micro it doesn't work. I am testing it with the UDPSendReceiveString example. I am not using the SD card writer. The pins I have connected are
| Ethernet Shield |
Uno |
Micro |
| GND |
GND |
GND |
| 5V |
5V |
5V |
| 3.3V |
3.3V |
3.3V |
| MISO(ICSP) |
12 |
MISO(PIN) |
| MOSI(ICSP) |
11 |
MOSI(PIN) |
| SCK(ICSP) |
13 |
SCK(PIN) |
| 10 |
10(SS) |
SS(PIN) |
| RX |
RX |

| TX |
TX |

I want to think it is the SS pin on the micro but I don't know enough about it to go about testing that.
Any help would be greatly appreciated!

Just to help anyone else. It was simpler than I thought. I just moving the wire from SS on the micro to 10 and it worked!
