These changes are for enabling unified accelerometer vibration and clipping
calculation. For that, we need the values "rotated and corrected" before they
are filtered and the calculation must be called as soon as a new sample arrives
as it takes the sample rate into account.
Thus, move code that applies "corrections" to be executed as soon as accel data
arrive and call _publish_accel() passing rotate_and_correct parameter as false.
Also, do the same for gyro so we can keep it consistent.
This commit changes the way libraries headers are included in source files:
- If the header is in the same directory the source belongs to, so the
notation '#include ""' is used with the path relative to the directory
containing the source.
- If the header is outside the directory containing the source, then we use
the notation '#include <>' with the path relative to libraries folder.
Some of the advantages of such approach:
- Only one search path for libraries headers.
- OSs like Windows may have a better lookup time.
Adapt the I2C driver to a system clock based wait_for_sample()
implementation.
The sample rate of the sensor has been corrected to 800 Hz (could be
further pushed up to 1KHz).
Filters for the mag have also been created but remain commented until
the code for the mag is ready.
The MPU9150 is a 9 axis sensor that includes 3 accelerometers,
3 gyroscopes and 3 magnetometers. All accessible through I2C.
The AP_InertialSensor_MPU9150 class allows APM to use this sensor.
