LCD Controller Questions

I understand PBP supports parallel LCD's that use the Hitachi HD44780U controllers. Does this also include the clones : Samsung KS0066U, Sitronix ST7066, and the Sunplus SPLC780A1 used in the Hantronix displays? If so I assume the code will be the same with no variations necessary? Are the serial displays using the same basic controllers and adding the RS-232 interface? Just now getting into this part of the micro C experience and trying to avoid the pitfalls.

If it's a 'clone' then it should work - otherwise it wouldn't be a 'clone' would it?

Yes, Serial LCD displays are little more than an LCD with (usually) a microprocessor accepting a two-wire Serial Input (Ground & Data) and outputting everything it receives straight to a conventionally connected parallel LCD.
