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…
