I've acquire one of these LCDs, and proceeded to set it up. When plugged in to the computer it does its little intro along with the song, "Parallax Inc," etc etc, so it DOES work. Now, when I upload a sketch via the Arduino environment, nothing happens. I'm using the test code available on Parallax's site, and when I compile it no errors arise. I've tested my arduino chip with the blink program and it functions, so I know that the Arduino chip works.
Any idea why my sketches aren't working with this LCD and the intro text continues to run?
