Leonard Hall a11a1db58b Filter: Support changing update period 2023-01-08 21:03:25 +11:00
Andrew Tridgell 5d29027025 Filter: allow for expansion of dynamic filters 
this allows for the number of dynamic filters on a harmonic notch
filter to expand at runtime, which allows for ESC RPMs to be populated
from other than AP_Motors, such as with lua scripts or for fwd motors
in a SLT quadplane

Andy Piper 5279ff5ce1 Filter: optimize notch filter frequency updates when the requested frequency has not changed 2022-10-04 13:38:30 +11:00
Andy Piper 0577407ff1 Filter: constrain harmonic notch center frequency changes to be within a slew limit 
raise notch filter slew for smaller aircraft
ensure NotchFilter init() resets the center frequency

Andrew Tridgell d07761cfd9 Filter: fixed reset of notch filters 
when we reset a notch we need to init the stored values to the current
value, rather than assuming that zero is the right value

this matters when switching IMUs in flight when we are only running
notch filters on the active gyro
