$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.
Notes
Currently only Linear Offsets (X and Y) 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”.
