The current practice of adding topics to the default set isn't scalable,
as it affects all setups.
By making sure topics are advertised on init, logger can just discard
topics that don't exist. This does not work for all topics, so topics are
specifically marked as optional. It can be extended to more topics later
on though.
This reduces the list of topics by ~35 on a pixracer configured as quad,
and reduces RAM usage by ~1KB.
Main UAVCAN protocol handling and ESC updates run on the same thread/wq as
before. There are 2 WorkItems for separate scheduling of the 2, so that
ESC updates run in sync with actuator_control updates. UAVCAN is scheduled
at a fixed rate of 3ms (previously the poll timeout) and on each UAVCAN
bus event.
This leads to roughly the same behavior as before. CPU & RAM usage are
pretty much the same (tested on Pixhawk 4).
Testing done: Motors still work (with feedback), param changes and a
UAVCAN optical flow sensor.
esc_setpoint in UAVCAN was just wrong, this is what it really is:
uint7 power_rating_pct # Instant demand factor in percent
(percent of maximum power); range 0% to 127%.
- move most orb to uORB::Publication and uORB::Subscription
- update legacy message handling (warn to PX4_INFO, PX4_WARN, PX4_ERR)
- add perf counters
- sensors/mag support newer `uavcan::equipment::ahrs::MagneticFieldStrength2` message
- sensors/gps support `uavcan::equipment::gnss::Auxiliary` for hdop and vdop
- sensors delete obsolete ioctl and read methods
- use PublicationMulti for actuator_outputs and esc_reports (to coexist with other output modules)
- add GNSS parameter metadata (parameters_injected.xml)
- there is a timeshift between the esc and px4 time so until there is some
kind of offset estimation we are better off using px4 time since the logging
system uses that as reference
