this is a partial backport of #24132 which fixes RTK injection when
the 1st GPS module is a DroneCAN RTK rover. Without this change RTCM
injection for RTK fix on the base will only work if it happens to come
up as the first module
filter status was initially set to zero then updated. This interacts
with the IMU filtering code which checks filter status from a
different thread to determine active_EKF_type(). When the race
condition is hit then the IMU we are running notch filters on changes
for a single sample, causing a notch filter glitch
add bi-directional dshot
add back in features.
juggle DMA allocations to allow CRSF to work correctly
disable dshot on PWM 10 as it is not used
do not enable quadplane by default
do not disable arming checks
run ICM42688 at 1Mhz for low speed to avoid gyro noise
add HEEWING README and picture
this was already done on many (most?) boards, and greatly reduces DMA
sharing which improves performance of UARTs. This changes the default
to no DMA on I2C
this fixes an issue where a lua library function triggers an exception
after it does a math operation which changes the floating point
registers on M7 MCUs (such as STM32H7). An example is math.random()
which calls math_random(), which pre-calculates a double value before
checking if the arguments to the call are valid. When it then checks
and finds invalid values the exception longjmp does not restore the
floating point registers.
this limits the amount that rate gains can reduce from the original
values in a quicktune. Large reductions in rate gains can be
incorrectly triggered by a frame resonance or gust of wind which can
result in gains that are dangerously low, which can trigger an angle P
oscillation
The ResetVelocity() function is only supposed to reset XY states, not
Z state. Resetting the Z state for velocity results in a large
velocity glitch if a vehicle is descending or ascending when aiding
switches to AID_NONE
this fixes#19386
