$PAMTC,COMP,Q
Summary
Query the weather station for the stored user compass calibration coefficients.
Syntax
$PAMTC,COMP,Q*hh
Reply
The weather station will reply with:
$PAMTR,COMP,Q,
<1>,<2>,<3>,<4>,<5>,<6>,<7>,<8>,<9>*hh
where fields <1> through <9> contain the data from the weather station’s
nonvolatile EEPROM corresponding to the fields as follows.
All fields are 16-bit signed fixed point decimal integers.
<1>
X axis Gain value, hundredths used as multiplier.
<2>
Y axis Gain value, hundredths used as multiplier.
<3>
Z axis Gain value, hundredths used as multiplier.
<4>
X axis linear offset, hundredths of micro-Teslas.
<5>
Y axis linear offset, hundredths of micro-Teslas.
<6>
Z axis linear offset, hundredths of micro-Teslas.
<7>
X axis angular offset, tenths of degrees.
<8>
Pitch and Roll Damping, twentieths of a second.
<9>
Compass/RateGyro Damping, twentieths of a second, negative
numbers indicate that the rate gyro is to be used in compass
computations.
Notes
Currently only Linear Offsets and Damping values are supported.
If in user calibration mode, the “Q” will be replaced by “INPROGRESS”.
If a user calibration pass has been completed, the “Q” will be replaced by
“PASS” or “FAIL”.
