I am using Arduino Uno board.
I am trying to connect and print a hello world-message in a LCD Display ADM12864H (http://www.sparkfun.com/commerce/product_info.php?products_id=710). I follow the instructions in this link: http://www.arduino.cc/playground/Code/GLCDks0108
I am not using the PIN 3, PIN18 and the PIN20 I connected directly in the 5V of arduino board.
I already tried more than 4 different samples since a simple retangular to the sample in the link of the instructions (http://www.arduino.cc/playground/Code/GLCDks0108).
I just cannot see anything. The background light is turned on, but nothing is shown.
(I already rechecked the pins in include file).
Am I forgeting something or do I need change the contrast to see anything?
