seconds.
MAG_CAL_FIT
UINT8
Value indicating how well the current
magnetometer calibration can fit the measured data
to an ideal “sphere” (or perfect calibration).
Values are encoded as a percentage from 0 to 100.
Accelerometer Calibration Fields
If the message STATUS_OUTPUT parameter contains the ACC_CAL bit (see
then the following fields are sequentially appended to the message record.
The fields are commonly used to assist in calibrating the accelerometer hardware.
For details of axis definitions refer to section 9.3 on page 138.
ACC_LIM_MIN_X
INT16
Value that holds the raw accelerometer sensor
value that will be used to represent -1G on the X
sensor axis.
ACC_LIM_MIN_Y
INT16
Value that holds the raw accelerometer sensor
value that will be used to rep1G on the X
sensor axis.
ACC_LIM_MIN_Z
INT16
Value that holds the raw accelerometer sensor
value that will be used to represent -1G on the Y
sensor axis.
ACC_LIM_MAX_X
INT16
Value that holds the raw accelerometer sensor
value that will be used to rep1G on the Y
sensor axis.
ACC_LIM_MAX_Y
INT16
Value that holds the raw accelerometer sensor
value that will be used to represent -1G on the Z
sensor axis.
ACC_LIM_MAX_Z
INT16
Value that holds the raw accelerometer sensor
value that will be used to rep1G on the Z
sensor axis.
Raw AHRS Sensor Data Fields
If the message STATUS_OUTPUT parameter contains the AHRS_RAW_DATA bit (see
), then the following fields are sequentially appended to the message record.
For details of axis definitions refer to section 9.3 on page 138.
Values are sampled internally by the AHRS at a rate of 50Hz.
AHRS_RAW_ACC_X
INT16
The last raw accelerometer sensor value measured
on the X-axis.
This field is used during functional testing and can
be used to assist with the accelerometer calibration
procedure.
