The reason for this change is that RPi2 and RPi3 are compatible, and
hopefully all differences coming up can be resolved without ifdefs but
at runtime.
Reason: the value is easier to read & handle (for example plotting). In
most places the value is needed, not the integral.
Note that this breaks the replay format for sdlog2 replay
- voting is now at a central place instead of duplicated within the
estimators
-> this also means that estimators that did not do voting so far,
now have voting, like ekf2
- estimators requiring more than that can still subscribe to the raw
sensors
- allows sensors_combined to be 3 times smaller
- reduces logger, memcpy (cache) & RAM overhead
- all modules requiring only 1 or 2 sensor values now automatically get
the voted result
- this also adds voting to baro
Decreases the message size from 780 to 280 bytes.
In particular, all modules using sensor_combined must use the integral now.
The sensor value can easily be reconstructed by dividing with dt.
Voters now need to be moved into sensors module, because error count and
priority is removed from the topic.
Any module that requires additional data from a sensor can subscribe to
the raw sensor topics.
At two places, values are set to zero instead of subscribing to the raw
sensors (with the assumption that no one reads them):
- mavlink mavlink_highres_imu_t::abs_pressure
- sdlog2: sensor temperatures
If the failsafe state is ended when landed, we would switch back to
POSCTL and therefore take off again, however, all we want is stay on
ground and wait for the auto disarm.
The param COM_ARM_WO_GPS is set to 1 by default to allow arming without
GPS. This then sets a bool arm_without_gps which translates to
!GNSS_check in preflightCheck.
The deleted code conflicts with the failsafe handling in set_nav_state.
Also, flight termination was usually disabled by circuit breaker which
means this code had no effect anyway.
The param NAV_RCL_ACT was not implemented as described. Also, it has the
completely the wrong name. It should be a COM param and not NAV.
Therefore, remove the param and delete the partly implemented
and probably never used functionality.
Always use the DESCEND mode and not LANDGPSFAIL because LANDGPSFAIL will
try to loiter for some time and then request termination instead of
descending gently and trying to land.
