I just bought the LCD from sparkfun below: http://www.sparkfun.com/products/709
I am just trying to the hello world from the examples but I can only get the LED backlight to come on. What do you think is wrong? I have the D4-D7 connects to digital pins 5-2. Pin 2 to 5V, Pin 1 & 5 & 16 to GND, pin 3 to pot, pin 4 to digital 12, pin 6 to digital 11, and pin 15 connected to the pot for 4.2V (I haven't turn the pot because I wasn't sure how else to get 4.2V.
What should I look at?
