add filtered second and third harmonics and log them
make sure we use all of the gyro samples available on each axis rather than skipping
separate gyro update from fft start to minimize time in fast loop
add FFT_HMNC_PEAK to allow users to select which noise peak and which axis will be tracked.
make sure the self-test runs once and display the results
report self-test failure reason. make sure self-test runs for all windows.
always give logging a chance to run at IO_PRIORITY
add log message documentation
make sure the engine still runs even when the arming check has been disabled
record last FFT update time and cycle time and fallback to throttle estimate when update is too old
delay for longer in FFT thread between cycles to cope on F4
try really hard to get a viable frequency estimate
change range on MAXHZ/MINHZ to reflect that 50Hz is actually quite dangerous
swap the center peak for one of the shoulders if there is temporarily a closer match with the frequency trend
when FFT is disabled still log harmonic notch frequency
use distance matrix to find most appropriate peak
use a median filter to remove outliers before filtering
discount peaks that are relatively too low in energy
make sure harmonic fit is tracked for both potential targets
convert all gyro buffers to ObjectBuffer<float> for lock-free access
run all FFT steps inside the FFT thread
calculate cycle time and loop delay correctly
drop samples when the ring buffer is full
fix quadplane FFT reference calculation
re-enable harmonic test
use median for measuring in-flight FFT average as it's much more reliable
relax quadplane filter restriction
harmonic switching test
tighten frequency check and loop twice to avoid heisenbugs
new dsp peak detection algorithm
add DSP sketch with frequency ascii art
tool to generate gyro data frames from batch sampled DF logs
add generated data from real Y6B flight
allow fft_start() to use ObjectBuffer<float> for lock-free access
allow ObjectBuffer to be resized
If a long-running process drains the mavlink stream rather than parsing
it then the cached timestamp can be very, very out-of-date. When we
next receieve a timestamp, then, there can be a signficant change in
time when we weren't expecting it.
run_cmd_get_ack can't use get_sim_time() as it might swallow the ack it
is looking for.
