Finally got text on the new display for #LT6502b
Wow it’s complex to get going.
No scrolling working yet and a few other issues to work through.

Oh, at last a open 2D printer! I've been waiting for this. If it's successful, It'll be the last printer I buy.

Took another photo, tweaked settings to get the colours closer to the display.

Ah ha!!! I ordered the display with a font chip, which has an 8x16 font on.
After much work that now works fine, giving me 37 lines per screen by 128 characters.
It does have a Yen/Yuan symbol instead of a dollar, but there is a variable width font with the dollar, so I can in theory swap the Yen/Yuan for a dollar on the fly later in assembly.
The viewing angle and contrast on this panel is also fa better than the previous one, image is a bit washed out still.

I got text running, but the font is 12x24, and there is no 8x16 sadly :(
So only 25 lines on this screen, but 85 characters wide.
Would be nice to get an 8x16 font on here :(

#LT6502b screen is now alive, just a solid block fill for now, but it’s working. 16bit colour and 1024x600.
Text will be the next thing to get working.
I will say, wow it’s a complex screen to setup.
