It'll chop up the menus, but if that doesn't bother you....

FWIW the hd44780 spec doesn't allow for displays that big, they're handled as two 4x20's, IIRC, or two 2x40's, if I don't ;)

Edit: I don't RC at all ;) a 4x40 works like two 2x40's stacked atop one another. See my next post.

TK recommends two 2x40's yeh. According to the doc I always refer to a 4x40 will interface in pretty much the exact same way. I should have remembered that I'm using FF now and I can search my bookmarks :) I've edited my last post.

In short: Yes, it'll work, No coding req'd... But it might look funny. Check out TK's Screenshots page for an idea of what will get broken up.

The chopping of menus is not a big deal. They will be cut in the same place as with two 2x40:s. But I cant find any info on what pin E2 shulod be conected to on the CORE?

I am also planing to use encoders with "buttons" insted of the 16 step buttons. If it´s not a bad idea? ???
