hi,
Look at this pdf, it will help.
Most controllers are KS0066 types.

hi,
Did you look at the link I posted.?

What sort of help are you asking for, wiring connections, programming etc.???

EDIT: which language are you going to use for programming.??? 'C' or assembler.

sooo simple ...

Hi, Marquey ...

Can't be simpler :

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 !!!

 

[markey]

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.

 

[markey]

yes...i had look the link that you have given....

 

[markey]

Give me your sample program using Pic Basic Pro,....tnx

hi,
From checking the LCD data on the web and other queries about the compatibility they appear to be the same.?

Look at this link:

EDIT:
Look at this pdf.

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)?

Soooo, It's rather simple :

Just provide YOUR scheme and YOUR code ...

NOT those from the book !!!

Just one idea ... could you show us your datasheet here ???

Another ( good ) idea ... which is the voltage on the LCD Contrast pin ??? ( Vo @ Pin 3 )
