Parallax Serial LCD w/Speaker Issues

Other Hardware Displays
1

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?

I'll have a better idea after I get my crystal ball back from the repair shop.

I don't really know what else to tell you, just wondering if any one else has encountered this issue, the arduino chip works, the display works, the code isn't calling an errors when I compile it, Is it a terrible thing to ask if anyone has any suggestions?

No.
Why not post exactly what you've done?
Get it out there.
Copy & Paste.

  1. Plugged in the serial LCD screen as stated by the instructions (Here: Microcontroller KickStarts | LEARN.PARALLAX.COM )
  2. Start-up tone and introduction message play on display when the chip is plugged in.
  3. Loaded up the demo sketch as supplied by parallax. (Here: Microcontroller KickStarts | LEARN.PARALLAX.COM )
  4. Nothing happens when sketch is ran.
  5. Reset button pressed.
  6. Step 4 repeated.
  7. Load up blink sketch, it functions.
  8. Tried other sketches for this serial LCD, nothing happens.

That's what happens, not more to it.

Make sure your connections are correct.
Don't tell people trying to help you "I've done everything the right way, i'm sure of that".
Assume you made a mistake.
It's difficult to see your own mistakes, or else you wouldn't have made them.
So show what you've built perhaps by uploading a photo of your setup.

You did blink to be sure the Arduino is OK.
Did you also blink pin 6 and wire a LED (of course with resistor) ?
Did you do blink while the display is connected ?
Did you try to use another pin besides digital 6 ?
Did you set the DIP switches correct ? <- Best guess.

We can ask a thousand questions, and still don't know what we're dealing with here.
