  21 *
  22 * Contains platform specific information on how to configure the MPU6050 to
  23 * work on this platform.  The orientation matricies are 3x3 rotation matricies
  24 * that are applied to the data to rotate from the mounting orientation to the
  25 * platform orientation.  The values must be one of 0, 1, or -1 and each row and
  26 * column should have exactly 1 non-zero value.
