9   -   DB2

10   -   DB3

11   -   DB4

12   -   DB5

14   -   DB7

15   -   A(LED+)

16   -   K(LED-)

I’ve drawn a wiring diagram here : http://homepage.ntlworld.com/keith.williamson/misc/lcd.jpg (40kb)

Is that wiring correct? Do I need the green lead to be connected like that?

TIA!

EDIT: Oh i forgot to mention I’ll be using it with the MBHP core, with a PIC18F452 if that matters  ::slight_smile:

huumm if you use the MBHP core module, you don’t have to do anything than wire the LCD, I mean, no contrast pot, because it still on the core module!

Vee connected to V0… that’s all!

Ahhh! I see  ::slight_smile:

Thanks buddy!
