I have a 28X2 which keeps busy with four continuous tasks, and I want to occasionally change the contents of word variables in that chip from a second Picaxe chip which could be an M2 or X2 chip, or whatever is optimal for the job.
I'm kind of overwhelmed by the various means of doing this and by their various advantages and disadvantages because this is an entirely new area (chip-to-chip comm) for me. The information transfer will happen across wires between two co-located circuit cards.
Is there a single obviously best way to move data into the 28X2 chip which cannot pause very long from its other duties? Advice very much appreciated.
