I have an application that I would like to distribute the processing between multiple PICs. One PIC to create output values and another to receive data from other sources.
Just curious why you need two PICs to do that. A couple people pointed to these types of devices for fast writes. And some of them are good for a 100 trillion read/writes (wonder who had to count those). http://www.ramtron.com/products/nonv...ry/serial.aspx (The 3volt type are even faster)
