Note: This parameter is for advanced users

The orientation of a third external compass relative to the vehicle frame. This value will be ignored unless this compass is set as an external compass. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. Rolling the vehicle upside down should decrease the MagZ value. For southern hemisphere, switch increase and decrease. NOTE: For internal compasses, AHRS_ORIENT is used.

Note: This parameter is for advanced users

Note: Reboot required after change

Size of window to be used in FFT calculations. Takes effect on reboot. Must be a power of 2 and between 32 and 512.

Time and frequency resolution are given by the sample-rate / window-size. Windows of 256 are only really recommended for F7 class boards, windows of 512 or more H7 class.

Range
32 - 1024

Percentage of window to be overlapped before another frame is process. Takes effect on reboot. A good default is 50% overlap. Higher overlap results in more processed frames but not necessarily more temporal resolution. Lower overlap results in lost information at the frame edges.

FFT harmonic fit frequency threshold percentage at which a signal of the appropriate frequency is determined to be the harmonic of another. Signals that have a harmonic relationship that varies at most by this percentage are considered harmonics of each other for the purpose of selecting the harmonic notch frequency. If a match is found then the lower frequency harmonic is always used as the basis for the dynamic harmonic notch. A value of zero completely disables harmonic matching.

Range
0 - 100

FFT_HMNC_PEAK: FFT harmonic peak target

Note: This parameter is for advanced users

The FFT harmonic peak target that should be returned by FTN1.PkAvg. The resulting value will be used by the harmonic notch if configured to track the FFT frequency. By default the appropriate peak is auto-detected based on the harmonic fit between peaks and the energy-weighted average frequency on roll on pitch is used. Setting this to 1 will always target the highest energy peak. Setting this to 2 will target the highest energy peak that is lower in frequency than the highest energy peak. Setting this to 3 will target the highest energy peak that is higher in frequency than the highest energy peak. Setting this to 4 will target the highest energy peak on the roll axis only and only the roll frequency will be used (some vehicles have a much more pronounced peak on roll). Setting this to 5 will target the highest energy peak on the pitch axis only and only the pitch frequency will be used (some vehicles have a much more pronounced peak on roll).
