Hi, I built one of these and although I've got it looking great with single colours, it's messed up for anims.
I've got it hooked up roughly as the old diagrams showed. Now I look at your new diagrams and you’ve changed the legs/groups and I’m double confused.(Had to check google cache to make sure I wasn’t going insane!)
I'm not sure it's possible now to hook it up without changing in software... you say it can be changed, but I just don't understand where that happens.

Here’s what I have, could you explain how to remap the pins?

Using base layer LEDs for reference:
blue legs in columns on pins 2-5. equivalent to your group 2.
Greens in rows on pins 6-9 – equivalent to group 1.
Cathodes on 10-13 equivalent to group 3.
reds on 14-17 like group 4

I'll probably figure it out eventually by drawing rows/columns and swapping actual pins :) - it would help if you could id the legs for the base layer on the drawings.
Thanks for any help!
