Hi all,

1 ) I need to design the board that contain the 256 pics and 1 master pic. 256 pics need to send the data/report to master pic. I want to know the best way to do that. It's need to put the some interfacing chip to every 256 pics and the master pic for the communication? Or can be direct connected to master pic? What type of the communication can be use?

2 ) I want to share the clock source from 1 crystal. What is the maximum pic can be connected to 1 source crystal? ( clock out from pic to other pic).


Thanks All.
