I got hold of a new 128×160 LCD that uses a parallel interface. This is better in many ways, not least of which are that the image is stable and doesn’t flicker like the old one.
Its faster to draw, and I can READ back contents of the lcd memory! this means I can grab parts of the image and re-paste them etc, or use xor to draw a pointer on the screen and xor it back off after.
I’m sure you can see where I’m going with that! Anyway, check out the old page and the new video as right at the bottom.
