Glad you are having fun. It’s such a nice display!
Yeah, it would be great to post some cool stuff to YouTube or something!
Are you using the RGB Matrix Backpack board? It sounds like you are using an Arduino and an IDC cable. This is the forum for the nootropic design backpack board. For help with the panel, I suggest the Adafruit forum:
http://forums.adafruit.com/viewforum.php?f=47Good to hear it works. The Adafruit library has a bunch of examples, and one is scrolling text.
File -> Examples -> RGBmatrixPanel -> scrolltext_16x32Have fun!
Yes, there’s a link in the last paragraph here:

http://nootropicdesign.com/matrixbackpack/downloads/MatrixDemo.zipSome questions that may help:
What type of power supply are you using? Is it center-positive?
If the voltage regulator is hot, then polarity is reversed or there is a short between GND and VCC. But it sounds like you have resistance between them.
Are the two electrolytic capacitors oriented correctly?
Are you sure you have the 74LS247 and 74HC595 chips in the right position and oriented properly? Soldering on the back looks good.
Why don’t you read the documentation and projects yourself? I spent many many hours documenting the product and the projects so that you could learn on your own. Do you understand?
This project shows how to display text on the screen.

http://nootropicdesign.com/ve/You cannot use interrupt-driven communications (like I2C) while displaying video, so you will need to account for that.
Best of luck.
If you want help with a project, you need to explain what you are trying to accomplish. The code you linked to seems to read data from an accellerometer. What are you trying to DO with this data? What is not working? I don’t see any Video Experimenter code in that code.
What role does the Video Experimenter play in your project? Where is your code that uses the Video Experimenter? Have you successfully done anything with the Video Experimenter? There are simple projects on the web site.
You must provide lots of information if you want help…
What is a “6dof IMU”?
You need to provide much more information if you want help. For example, you could provide your code. Please properly format your code with code tags like this:
foo = bar;Are you using the special TVout library from the nootropic design website? Overlay does not work with the TVout lib from Google Code.
What kind of Arduino are you using? This works on Uno and Duemilanove.
Did you assemble the electronics yourself? If so, then you may have a short somewhere…you can send a picture of the soldering to support@nootropicdesign.com
Does the video output of the camera device show on the TV? That is, does the signal pass through the VE?
Have you tried another video source, like a DVD player or something?
