Andrew Tridgell f80ba734c8 AP_AHRS: removed use of "blended" accel values
calculate a single EF accel based on primary IMU
2022-08-21 18:51:59 +10:00
Andrew Tridgell 924759510d AP_AHRS: fixed use of filtered gyro with DCM active
we need to overwrite _omega with the filtered gyro value, so we get
both the low pass filter and the notch filters. Otherwise we will fly
with very high noise gyro data

this also fixes the accel_ef_blended to use the filtered accel. It is
not blended, and removing "_blended" from the API will be worthwhile
as a followup

Peter Barker 29d2eed9e4 Sub: view update does not take skip_ins_update 2021-08-31 14:28:53 +10:00
Peter Barker 9dbd9d1e06 AP_AHRS: call INS update in AP_AHRS::update w/o holding data sem
We shouldn't be holding the data semaphore while waiting for the samples
- lots of things might be unnecessarily blocked

DCM's update function doesn't need to take the semaphore as it is
already taken by AP_AHRS

Andrew Tridgell 53e7436525 AP_AHRS: allow for fallback to DCM in quadplanes
this adds the necessary functions to allow for flying a quadplane on
DCM as an emergency fallback. It sets the NavGainScalar to 0.5 to
reduce the VTOL controller gains to allow planes to cope with the
higher lag of DCM

Peter Barker 8daa0a099c AP_AHRS: rename yaw_initialised access method to dcm_yaw_initialised
This is what it really means.

Also put the relevant state within the DCM object

Peter Barker 608608f32f AP_AHRS: internalise application of correct_centrifugal
This is a DCM-only option but that's not clear with the interface.
Internalise the variable and base it off build type.

Harshit Kumar Sankhla b5b3298f0a AP_AHRS: get airspeed estimate from non-primary instances too
with multiple airspeed sensors and airspeed affinity in EKF3,
it is possible to have switched over to a lane not using the
primary airspeed sensor, so AHRS should know which airspeed
sensor to use, i.e, the one being used by the primary lane.

Andrew Tridgell 0ccaa5bcba AP_AHRS: removed create() method for objects
See discussion here:

  https://github.com/ArduPilot/ardupilot/issues/7331

we were getting some uninitialised variables. While it only showed up in
AP_SbusOut, it means we can't be sure it won't happen on other objects,
so safest to remove the approach

Thanks to assistance from Lucas, Peter and Francisco
