hi
I'm sure that this came up before but a couldnt find it..
i have a mega 2650 and v1 ehternet shield.
in order to make it work, i had to connect pins 50 to 12, 51 to 11 and 52 to 13.
once i connect them it works great.
i'm in the middle of a smart home project and i really need all the pins i can get.
is there another way to use it without connecting these pins together?
I presume the ethernet shield does not have the ICSP connector on the bottom? You can "pin bend" D11-D13 on the shield, and connect those to the ICSP pins instead. Most newer shields that have SPI devices onboard use the ICSP connector for the SPI data lines.
That will free up D11 to D13 on the Mega.
edit: You don't really need to jumper to the ICSP connector. The Mega uses D50-D52 for the SPI data lines like the Uno uses D11-D13, so you can't use those for anything else anyway. Just bend the pins.
