I am sorry guys if I didnt make myself clear. So here is an another attempt.
I am trying to view the output of MPU6050 (gyrometer + acclerometer) in Processing IDE. I added the FreeIMU library in arduino and then executed the FreeIMU quaternion code from the examples. I was able to see the change in data values in the serial monitor of arduino. Now I wanted to see a graphical output using Processing IDE using FreeIMU Cube example. I am just not able to proceed furthur from here. Kindly provide me with the steps from here onwards. See video: https://www.youtube.com/watch?v=gU9vM0UE3Ug
