As the reference says:
"Arduino communicates with the shield using the SPI bus. This is on digital pins 11, 12, and 13 on the Uno and pins 50, 51, and 52 on the Mega. On both boards, pin 10 is used as SS. On the Mega, the hardware SS pin, 53, is not used to select the W5100, but it must be kept as an output or the SPI interface won't work."
If i have to use pins 51 and 52 for Ethernet Card, how should I connect my Digital Led Strip That needs the ports 51 and 52 (data and clock) to work??!?
Sorry really new in the hardware and electronic section! Programming is the easier part for me.
Any help is appreciated!
Last:
Just by popping on the ethernet shield on my arduino mega i can send and receive data, but when I start to use SPI for the digital led strip, everything goes wrong.

Yeah, I figured I need 2 separate SPI. So I cannot use a ethernet shield and a Digital addressable led strip that both uses SPI on a Arduino Mega 2560?
Is there any solution for this? Bought the biggest Arduino, still can't handle this simple task? :o
