Driving a HD44780 is as simple as it gets on a PIC, LCDOUT some text and
that's it.

Serial LCDs, now you're getting into some heavy stuff.  You can do it, but
it's not a walk in the park like a parallel HD44780.  There are several
controllers out there, figuring out the required code is not easy for a
novice.  If you're lucky, someone out there already has posted what you
need.

Some LCDs have a built-in font, some do not, some have lousy documentation,
some don't even have a controller.  Here are just a few controllers to give
you an idea of the variety, and I'm sure there's tons more:

Epson S1D15G00
Epson S1D13700
Epson sed1330
Epson sed1520
Epson sed1565
Hitachi hd66712u
Novatek nt3881d22
Samsung ks0066u
Samsung ks0108b
Sanyo lc7981
Sitronix ST7066-0A
Sunplus lc780a1v15
Toshiba T6963C
Toshiba T7932

If I had to recommend one as a starting point, the Toshiba T6963C.  It may
not be the best, but it is flexible and there are several examples of PIC
BASIC Pro code out there (assuming you are using PBP).  Also, controllers
have hardware limitations; the T6963C cannot drive a 320x240 pixel LCD.  And
that's another thing, pay attention to what controller you will be using.  I
had to learn several before I ended up where I am, lots of frustration and
wasted time.

Good luck, and Google is your fiend; just search for the controller name and
PIC BASIC.
