Hey everyone,

I'm monkeying around with some Lynx stuff and there's a simple test I'd like to be able to run, but I don't really want to have to come up to speed on Lynx programming just to do it-- so I'm hoping that someone here would be willing to knock out a little test app for me.

In a nutshell I just want "color ramp" bars. Basically Red, Green, and Blue ramping from all bits 0 to all bits 1 on a horizontal sweep-- like so:



If you can help out it would be much appreciated!

Thanks,
-Clay

Not the easiest thing to do as the Lynx can only show 16 colors and you want 64.

So you could display 16 vertical boxes with indices 0 - 15. Then you need to set up an interrupt or for every scanline and change the palette.

Ah, right-- I forgot about the palette restriction. No worries though, got it figured out. Had a couple bits swapped and couldn't figure out where the problem was for a while. All good now.

Thanks!

Send us your code you monkeying around with, than we show you whats wrong.

the easy way is to draw it as single sprite. the other ways are depending on the type of programming language you want to use.
