Hi Richard,

for the schematic i think i'm ok. I can handle it. I keep saying because i know my self, that first i need to understand the basics. Even if you think that is too basic to read about SPI connection, i need to understand it, and get those small important information for me that will help me later.

Now i read this because i find it interesting (not the arduino code) but the information they share are useful. Like the " NODES " , Addressing, Broadcast addressing etc.

I have a long way.
