Hi John,

It really depends on what you call a GLCD. If it is a "serial GLCD" with
intelligence already embedded, then you should be fine with a 16F628, as yo=
u
would need to send simple commands and the GLCD will do everything. However=
,
if it is a kind of standard GLCD with no embedded functionality other than
setting a pixel on/off, then you need to implement arithmetic in your PIC t=
o
draw lines, circles, etc. All this takes significant RAM/ROM (significant
for what a PIC16F628) so you better go with a PIC16F2620 general purpose
PIC.

Cheers,
