selectively apply filters twice to make sure that FFT is not tracking itself
clean-up notch disablement for non-DSP builds
use filter gyro data for FFT when analysing post-filter
always apply LPF after all of the notches
move to a phased application of window information for FFT
tap FFT gyro window at the appropriate place for downsampled FFTs
add accessor for FFT notch
document notch uses cases and flow
provide method to determine noise at a particular frequency
add ability to record per-peak SnR
correct bad array indexing leading to free memory read
track all three axes for health and peaks
remove slewed frequency values, since slewing is now done in the filters
ReplayGyroFFT initial implementation
allow IMU data to be read and written from a file
only build Replay on SITL
correctly calibrate FFT in Replay
better noise simulation in Replay
FTN3 logging
allow FFT peaks to swap indefinitely as long as they both still exist.
Leads to much smoother frequency transitions
increase the energy gap required to switch the tracked peak
use exit on stop for Replay
filter noise tracking more aggressively for post-filter samples
remove message and use appropriate gyro window
when using post-filter do not fallback to throttle-based estimate
AP_GyroFFT: default SnR to 10 when using post-filter samples
Move get_link_rate() and get_protocol_string() to CRSF protocol
allow ELRS at 420kbaud to be configured
allow CRSF to bootstrap at ELRS desired baudrate
this copes with quadplanes with no compass. With a compass we are
better off using EKF when not in fly-forward as it will give better
height control.
This makes QHOVER for takeoff in quadplanes with no compass a lot more
flyable
this fixes a "climb away" in quadplanes when AHRS_EKF_TYPE=2 and
EK2_ENABLE=0. The user has ARMING_CHECK=5390 to disable key arming
checks, and the plane flew on DCM as the configured EKF wasn't
enabled.
This resulted in AHRS::get_origin() returning false as it couldn't ask
EKF2 for the origin (as EKF2 was not enabled or instantiated)
The result was an incorrect calculation for target height during the
descent stage of QRTL, resulting in a climb away until the user took
over
