I'd prefer not to use another micro, if i really had to it would be an  
atmel so is it compatible with the rest.

There's also a schematic out there showing how one can use an attiny or  
someting with very few (like 2 or 3) outputs to drive a hd... parallel  
LCD. I think they used a simple shift register.

Anyway, not sure, i guess i would even prefer LED display here...

Probably easier for me to just use a standard led panelmeter circuit  
(should have some of those around) and do the rest of the control analog  
as well.
