- create common uORB::PublicationBase
- uORB::PublicationQueued types are now type aliases
- ORB_PRIO use enum type everywhere to avoid accidental misuse
- PX4Accelerometer/PX4Gyroscope/etc driver libs explicitly advertise on construction, unadvertise on destruction. This is a workaround for any potential issues that might appear when accel/gyro cdev and uORB indexing doesn't align.
- this is a new module for temperature compensation that consolidates the functionality previously handled in the sensors module (calculating runtime thermal corrections) and the events module (online thermal calibration)
- by collecting this functionality into a single module we can optionally disable it on systems where it's not used and save some flash (if disabled at build time) or memory (disabled at run time)
- split out integrated data into new standalone messages (sensor_accel_integrated and sensor_gyro_integrated)
- publish sensor_gyro at full rate and remove sensor_gyro_control
- limit sensor status publications to 10 Hz
- remove unused accel/gyro raw ADC fields
- add device IDs to sensor_bias and sensor_correction
- vehicle_angular_velocity/vehicle_acceleration: check device ids before using bias and corrections
The bulk of this change was tightly coupled and needed to be deleted in one pass. Some of the smaller changes were things that broke as a result of the initial purge and subsequently fixed by further eradicating unnecessary platform differences. Finally, I deleted any dead code I came across in the related files I touched while going through everything.
- DriverFramework (src/lib/DriverFramework submodule) completely removed
- added dspal submodule in qurt platform (was brought in via DriverFramework)
- all df wrapper drivers removed
- all boards using df wrapper drivers updated to use in tree equivalents
- unused empty arch/board.h on posix and qurt removed
- unused IOCTLs removed (pub block, priv, etc)
- Integrator delete methods only used from df wrapper drivers
- commander: sensor calibration use "NuttX version" everywhere for now
- sensors: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- battery_status: update to px4_{open, read, close} instead of DevMgr wrapper (adc open for analog differential pressure)
- cdev cleanup conflicting typedefs and names with actual OS (pollevent_t, etc)
- load_mon and top remove from linux boards (unused)
- delete unused PX4_MAIN_FUNCTION
- delete unused getreg32 macro
- delete unused SIOCDEVPRIVATE define
- named each platform tasks consistently
- posix list_devices and list_topics removed (list_files now shows all virtual files)
By using the uORB::Subscription API we use a separate subscription
rather than `orb_copy` on the existing file descriptor used in
sensors through `px4_poll`.
This fixes a very peculiar problem that we observed in SITL in CI for
fixedwing. The events were as follows:
1. `sensors` does `px4_poll` on the gyro topic (as normal), and gets
the latest sample using `orb_copy`.
2. A parameter update happens when the mag is initialized and triggers
`VotedSensorsUpdate::parameters_update()` where `orb_copy` happens
before the main loop in `sensors` has started a `px4_poll`.
3. `sensors` now does the `px4_poll`, however waits indefinitely because
it has already copied the latest sample.
Also, the `px4_poll` will never time out because in lockstep the
simulator waits for the next actuator control message which it never
gets and therefore it never sends the next sensor message with a new
timestamp to advance the time.
This only happens for fixedwing because there is only one "uORB path"
through the system unlike for multicopter where a gyro sample can get
picked up by either `sensors` or directly `mc_att_control`, so the
system can survive if `sensors` has "drops".
Temperature compensation is not supported in HITL. Therefore, don't try
and fail. This basically removes the confusing error message that we get
in HITL.
When a gyro driver is stopped, the topic is unadvertised and
orb_group_count() returns a smaller count. This can have the effect, that
we poll on a certain gyro fd, but since _gyro.subscription_count is reduced
we never do the orb_copy for that fd.
This cannot happen when armed. And only someone playing with the shell
can trigger it (sensor failures do not have that effect).
When determining the confidence of a barometer sensor, we should
consider the temperature as well, alongside the pressure.
Low-noise baros can show the same pressure reading for a second
or two when not moving and in an indoor location.
