mega + ethernet/sd shield + rfm12 possible ?


I want to use the latest official arduino edthernet/sd shield together with the rfm12 tranceiver on the same mega2560.

All the parts seperated works (I tested the sd read/write), the rf transceiver...

But when I connect them together the sd card init fail (suppose due to multiple spi devices on the same bus).

Does anyone know a solution for this problem ?

Thanks in advance, Jeroen


it works. So I can confirm it works, but I was mislaid. I noticed that sometimes after uploading a changed sketch, you neen to realy power of the boards (instead of just a reset).

Best regards, Jeroen.
