Hi Steve,

Thanks for your continued support.

I placed the additional define statement in the program. It still did not work.

I'm at home now and have wired up an Optrex DMC16230 2 x 16 display. It works!

So... the problem is either with the code... subtle differences with the DMC20481? Or timing? Or maybe it needs to be wired slightly differently? I wired the 230 exactly the same way as the 481.

I don't know... I'm guessing here.

At least the board checks out. I was starting to wonder.

To restate the problem... I am trying to coax an Optrex DMC20481 into spitting out some characters. As of right now. it just sits there... blank. And I do mean blank. It don't flicker, it don't make black squares... it don't do nuttin!

Could go for some more ideas... anyone... anybody? HMMM???
