when you have a moving baseline pair of ublox GPS modules and the
rover GPS does not have full fixed RTK lock on the base GPS then we
should not use it as our primary GPS as it's position and velocity can
be badly affected by the attempts of the GPS to gain a fixed lock.
This was observed in a flight with two F9P GPS, where the GPS velocity
data from the rover GPS went way off when it lost full RTK lock. It's
status stayed at 4, so it was selected as the primary GPS
Units are not associated with the CurrTot message. AP_BattMonitor.h indicates the total current consumed is reported in mAh. This change sets the units for CurrTot to Ampere seconds and applies a multiplier of 3.6 to convert the reported mAh value to Ampere seconds.
general scheduler delays could introduce small delays when writing SPort frames to the uart one byte
at the time potentially leading to rx desyncs on the SPort bus.
This fix replaces single byte writes with full frame writes.
The library has around 10ms to repond to polling so to guarantee frame integrity responses taking
longer than 7500us are discarded
This reverts the change from #13895 and instead resolves the issue by
increasing the scale factor limit to 1.4
There is an open question as to why some RM3100 compasses show a
different scale factor (by about 1.25 times) to other versions of the
same sensor. As we haven't resolved this properly it seems the correct
thing to do is follow the datasheet but allow for a wider range of
scale factors to cope with the variation between sensors
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
