=20 Thanks, Actually all diagrams has Pin 1 as VDD, but Diagram 2 has Pin 1 on the right, and Diagram 1 and 3 has it on the left (if you look from the back with the connector at the top). Did you run your PIC at 3V too? And did you use any resistors between = the PIC output pins and the LCD pins? Any other components for the = supply/reset pins? :-) _____ =20 Andr=E9 Miller =09 > This diagram shows Pin 1 on the left, with the connector facing up and = > the display facing away from you: > http://users.skynet.be/bk317494/datasheet/nokia_3310_LCD.jpg This is the pin out I used when I was working with the LCD. > All of them has the descriptions of the pins the same, but the second=20 > diagram has the pinouts numbered from the opposite side.
