I got to thinking about the many different P1 modules that I have designed in the past and then I thought how compact and easy to use the P2D2 is. Can I do the same for the P1?
Why yes, but I would allow for dual P1 chips with one driving VGA on P2D2s P0 side and the I/O all connected up there.
It would have the main or only P1 connected up to serial and flash and microSD etc. What a combination! Perhaps the 2nd P1 could have 4MB of serial RAM.
Just thinking at the moment while I get over this flu, but I will do a draft layout shortly.
