I got the teapot demo to work after MANY hours. My 6050 IMU GY-521 is connected with 5 wires GND,V+,SDA,SCL and INT. BTW you do need a reset button on the arduino (so the MiniPro will not work). Then make sure to edit the INO from https://github.com/jrowberg/i2cdevlib/tree/master/Arduino/MPU6050/Examples/MPU6050_DMP6 to enable teapot format output by commenting out 'yawpitch' and uncommenting the 'teapot' lines like so: //#define OUTPUT_READABLE_YAWPITCHROLL #define OUTPUT_TEAPOT Make sure the baud rates are the same in the INO and the PDE: Then run the processing PDE from the below link (with the toxiclib PDE library installed): https://github.com/jrowberg/i2cdevlib/tree/master/Arduino/MPU6050/Examples/MPU6050_DMP6/Processing ... After a few seconds you should see a small window pop up with an airplane in it. If it does not move, just press the reset button on the arduino and the plane will start moving. I am running win7 32bit and Java V7, PROCESSING V2 and IDE v 1 05 . I also found that If I get Java error messages, the only way to correct this , is to reboot the PC.
