It makes more sense to set the optimization flags on a platform basis
instead of individually for each module. This allows for different
optimization options for SITL, NuttX, Snapdragon, etc.
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
GCC output:
implicit conversion from ‘float’ to ‘double’ to match other operand of
binary expression [-Werror=double-promotion]
It seems gcc 6.1.1 uses the float variant of fabs, whereas older gcc's
use the double version. This makes it compile for both.
Make sure `struct position_estimator_inav_params params` is properly initialized.
At first there was no indication that this struct was un-initialized because valgrind
was issuing warnings about values that were derived (via float calculations) from
values in this struct. Maybe instruction re-ordering during optimization caused
this disconnect between the source of the problem and the symptom.
