1) just open your PBP manual ( the last online manual "PBPM 108" ) on page 95 ...
2) read the relevant chapter from beginning to end
3) where you will find connexions and scheme for both your processor AND LCD ...
isn't life marvellous ???

in other terms ... the answer is Read That F***ing Manual !!! ... KS0066 is a "44780 compatible" lcd Driver !!!
yes..i had read that manual but my LCD didn't work...i just want to know if there is a difference between the LCD display with 44780 controller and KS0066 controller.

Can I suggest that you take a step back. In what way does the LCD not work? What is the configuration you have at the moment?
Can you adjust the contract until you see the black rectangles? If you can then at least you know the power etc. is all working. (I suggest you back off the contrast so that the rectangles are just visible while you get things going - that way you know the power set-up is right but you can still see any characters that might be getting through; even the garbage ones).
Can you put a scope on the data lines and see the signals being passed to the LCD?
Have you programmed in the correct initialisation sequence and are the delays between the commands long enough (I've been bitten by this)?
