It's hard to go wrong with the PIC's, the PIC18F series is great, however you
would need a programmer like the ICD2 to work with it efficiently. Microchip
and Atmel provide great free tools for assembly language, however if you want a
c compiler the good ones cost money. If want C and can live with some
restrictions, I think you could do your project using the TI 420 chips, and
they have a cheap starter that comes with C. Another choice is using the Rabbit
Chips.

I know not much help, but just about any of the chips can do your intended
function, so asking how you want to create the software is a good distinction.

I checked and can see that the PIC and Atmel clocked serial modes will work
with that display, that beats bit banging it out I don't know much about the TI
chips as I have never used them.
