Hello! It's about this situation: I have 2 (in the future more than 2) Atmega328. One has the main program; the other I want to use it to colect data (digital/analogical) and to send the information to the main chip; there are more than 8 parameters to send.
Than, after the master chip precesses the information, it will send to the slave an order to drive up some pins. And so on...
I've searched for information that could help me, but I didn't find anything cogent.
Could somebody help me to do this?
