As they are always moving horizontally, the check doesn't make sense
for fixed-wings.
Also don't run the check while on ground to prevent getting a failed
check during pre-takeoff manipulation.
H7 Only supports 2 not 3 CAN interfaces.
CanInitHelper passes in in the run time configuration of
the number of interfaces. The code was ignoring these!
- on common IMUs like the mpu6000, mpu9250, icm20602, etc each FIFO
sample is only 12 bytes so this is still more than large enough for the
worst case transfer
- free memory is getting tight on these older boards (depending on
configuratoin) and the pixhawk 2 cube still has 2 other superior IMUs, so this is just
dropping dead weight
We use lockdown to prevent outputs like motors and servos from being
active in HITL simulation. This means that we can't treat the lockdown
flag as a flight_terminated, otherwise we can't arm in HITL at all.
Without this, uavcan creates MixingOutput classes which then create
empty actuator_outputs publications. This then prevents the motor
output in HITL to be forwarded to the simulator via mavlink.
This fixes an invalid memory access when exiting the module:
exit_and_cleanup destroys the object, but lock_guard is destructed after
and accesses the lock.
- this allows jumping straight to a non-SBUS RC protocol
- increased the scan time per protocol 300->500 ms, which the newer DSM parser seems to need in some cases.
- only set RC_INPUT_PROTO if we've had a successful RC lock for > 3 seconds
Normally _should_run for mission is only ever true if _should_run for the
normal log is. There are exceptions though:
- the log buffer fails to allocate
- there was a write failure (e.g. due to SD card removal)
In that situation, the writer would not wait anymore but busy-loop.
If both local position and altitude were not valid, then both RC loss and
datalink loss would not trigger any failsafe at all, independently from
the configured action.
Calculating K(HP) takes less operations than (KH)P because K and H are
vectors.
Without considering the sparsity optimization:
- KH (24*24 operations) is then a 24x24 matrix an it takes
24^3 operations to multiply it with P. Total: 14400 op
- HP (24*(24+24-1) operations) is a row vector
and it takes 24 operations to left-multiply it by K. Total:1152 op
Fixes a regression from c1e5e666f083f08ddca218aef86a22338c8020cd,
where with static mixers the dshot outputs would go to max instead of 0
in a failsafe case.
