I would like to add Ethernet to a existing project that uses a UNO. I have a Xbee connected to it using AltSoftSerial so that I can leave the on board serial port open for debugging and I don't run into the problems of downloading a sketch to the Xbee if I forget the switch, which I will.
The problem is AltSoftSerial uses Pins, 8, 9 & 10, the same pins the Ethernet shield uses. Are there any other options out there, I2C, SPI or whatever, to connect the UNO to the Ethernet?
Thanks for your help
