Starting a new thread as this is something of a milestone (for me anyway)...
This code is showing a 16-bit image stored in HUB RAM on a 4.3" LCD with 480x272 resolution.
This adapter only has 6 of the 16 color bits wired up though. But, I have PCBs on order that will give all 16 bits.
Note that LCD is actually 24-bit, but I'm thinking that it's best to work in 16-bit color or less.
Uses RDFAST and RFWORD to quickly read in words (16-bit color pixels) from HUB.
I have the lower 16 pins of OUTA (P0..P15) for the 16-bit color word.
This lets me use setword to push the next pixel to outa with ease.
Refresh rate is probably fairly low (have to measure), but real chip should have higher clock frequency, so maybe it's OK.
Again, image quality will improve when I get my new PCB...
BTW: You can see the jumper wires that were giving me some trouble in the photo. New PCB should fix that too.
