TouchShield Slide Programming Help!!!

Other Hardware Displays
1

I just got my TouchShield Slide a couple days ago, so I'm new to programming these shields. I can't seem to get the darn thing to do anything. After uploading the sketches onto my Arduino Uno and the TSS, I only see a white screen. I've tried numerous sketches from Liquidware and example sketches, but nothing seems to work. What does a white screen on the TSS mean??

Since you're new to the forum I guess I should point out that if you want to get your questions answered it helps to provide some
info. You should read this:
http://forum.arduino.cc/index.php/topic,148850.0.html but if you want to get the ball rolling you should provide:

  1. A link to where you purchased the shield.
  2. Any datasheets or links to them about the shield.
  3. The code you are running, either a file attachement or post it using the "#" code button to create a scrolling window so people
    can scroll through the code.
  4. A situation report (SITREP) on what (if anything ) you have tried thus far.
  5. If you don't have the link to the vendor then you need to post a photo of it.
  6. If it is already wired, then we need to know how you wired it (what to what)
  7. If you have nothing and have done nothing , you need to state that as well.

Thank you for pointing that out, my mistake.

I purchased the shield here: http://www.liquidware.com/shop/show/TSL/TouchShield+Slide+
The only documentation I can find on the shield is here: https://www.jameco.com/Jameco/Products/ProdDS/2127558.pdf
I am using an Arduino Uno for the project.
The code that I am using for the Arduino Uno is:

    Before uploading any sketches, I popped the shield on top of the arduino (I'm connecting it just fine).
    Then the first thing I did was upload the arduino sketch in the arduino IDE 1.05, and then I uploaded the shield sketch in the antipasto -0044 IDE. Everything compiles just fine, but overall does nothing; the screen turns white, and that's it. So my question is is it most likely a software/code issue? I don't think that is the case, I think it's a hardware issue. What does a white screen mean?

or post it using the "#" code button to create a scrolling window so people
can scroll through the code.

Highlight the code , then click on the "#" CODE BUTTON.
