  • For anyone that is struggling to get this sensor to work with an Arduino Leonardo using the libraries provided the example code link, I was able to get it to work by doing the following:

    First, the Leonardo I2C interface is detailed here: http://arduino.cc/en/Main/arduinoBoardLeonardo SDA -> Digital Pin 2 SCL -> Digital Pin 3

    Second, the Leonardo interrupt setup is detailed here: http://arduino.cc/en/Reference/AttachInterrupt The DMP6_test is setup to use interrupt 0 which is Digital Pin 2 on the Leonardo. I changed the line:

    attachInterrupt(0, dmpDataReady, RISING);

    to:

    attachInterrupt(4, dmpDataReady, RISING);

    And connected the interrupt to Digital pin 7.

    The DMP6_test and Processing sketch now works like a charm! I hope this helps anyone else that was struggling with the Leonardo setup.

No public wish lists :(
