Hi Mick,
I have ordered Peters design (through Plasma) as an HDMI platform with USB.
But this design could be a good alternative for VGA with USB. And it has the PSRAM. I know Peter wants to avoid PSRAM, but for VGA (where 252/325MHz is fine) the PGA could be a good solution. And the slow PSRAM only exhibits when you use too much main RAM. This is fully under the programmers control.
Things I would "change" (not saying I won't build it as is, but things I find desirable).
- a better programming header (I think I will have to re-program the firmware 100 time or more, given last years track record). Maybe a (vertical) USB connector, or something that is keyed, so it can't go wrong.
- a fullsize SD card slot with push-push. I play with the PicoGameVGA (where I have the same module you use assembled) and simply have trouble (eyes...?) putting the card in, and somtimes you do 10 times in an evening. I know it is a cheap module, but I like the full size more for convenience. And that can very well be on a module if one can be found on Ali.
Thats all...
