hello, im going to do harmonic notch filtering in my quad.
where can i find hover frequency?
in arducopter docs said :
Set INS_HNTCH_FREQ and/or INS_HNTC2_FREQ = below the hover frequency - you can easily determine this by performing a gentle hover and looking at the ESC telemetry data
So you don’t need to mess with INS_HNTCH_FREQ - just leave it at the default for now. All you need to do is set:
INS_HNTCH_REF=1
INS_HNTCH_ENABLE=1
INS_HNTCH_OPTS=2
INS_HNTCH_MODE=3
Do you have DSHOT capable ESCs, the telemtry (data) set up and “ESC” data in the logs?
You can check in Messages tab of MissionPlanner to see some message similar to: RCOut: PWM:1-8 DS600:9-14
that indicates which outputs are using DSHOT.
If you have verified that you have ESC data getting to the flight controller, then you just need you just need those settings that Andy listed:
