- IMU integration move from drivers (PX4Accelerometer/PX4Gyroscope) to sensors/vehicle_imu
- sensors: voted_sensors_update now consumes vehicle_imu
- delete sensor_accel_integrated, sensor_gyro_integrated
- merge sensor_accel_status/sensor_gyro_status into vehicle_imu_status
- sensors status output minor improvements (ordering, whitespace, show selected sensor device id and instance)
- 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 quick follow up fix to to a bug introduced by #14752. In the case of FIFO data (new IMU drivers) the calibration offset wasn't being applied correctly to the result of integrating the FIFO samples.
This slipped through basic sanity testing (simple bench testing, the test rack, and SITL CI) due to the calibration offsets being zeroed.
- bring in PX4/ecl#795 "EKF: Improve covariance prediction stability"
- the ecl/EKF filter update period has changed from 8 ms to 10 ms
- change default integration period 4000 us -> 2500 us (aligns with new EKF filter update period)
Supposedly multiple sensor callbacks were supported; in reality, this
was not the case, as the mag SensorBridge in particular can only
calibrate one compass, leading to a race condition on which compass
appears first on the bus to get published and calibrated (with no
warning to the user that the 'wrong' compass is being used).
For sensors with existing generic driver classes (baro and mag) the
sensor bridges use these classes for the driver registration, and uORB
publication, and calibration interface (ioctl) handling.
- the device path needs to be removed, as startup fails if it already
exists
- sdp3x broadcasts a reset on startup, so do it only for the first I2C
address
This avoids the need for recalibration, and also cleans up other driver
ID's (merge separate accel/gyro).
The SPI address was previously set to a board-specific (arbitrary) value,
and is now set to 0. This will allow extending for multiple sensors of the
same type on the same bus.
Chip-select and SPI initialization uses the new config, whereas the drivers
still use the existing defines.
The configuration in board_config.h can be removed after all drivers are
updated.
- refactor Run() into simple state machine
- perform reset and configuration in sensor bus thread
- when using data ready interrupt skip checking FIFO count
- checked register mechanism and simple watchdog
- driver checks for errors gradually and can reconfigure itself
- respect IMU_GYRO_RATEMAX at the driver level
- fixed sensor INT16_MIN and INT16_MAX handling (y & z axis are flipped before publishing)
- increased sensor_gyro_fifo max size (enables running the driver much slower, but still transferring all raw data)
- PX4Accelerometer/PX4Gyroscope remove unnecessary memsets
I've added a queue depth of 4 for sensor_accel and sensor_gyro. This is initially added because it's not always possible for the `vehicle_acceleration` to keep up with every publication of the primary accelerator as it runs in the same thread as ekf2, various controllers, etc.
Later this mechanism will be used in a few areas
- rate limit `vehicle_angular_velocity` and `vehicle_acceleration` without missing any raw data
- move IMU integration to `vehicle_imu` and out of the actual driver threads, eliminating the need for sensor_accel_integrated and sensor_gyro_integrated
- integrate raw gyro synchronized with optical flow measurements
- gyro filtering (low-pass and notch) only performed on primary gyro in `sensors/vehicle_angular_velocity` instead of every gyro in `PX4Gyroscope`
- sample rate is calculated from actual updates (the fixed value was slightly wrong in many cases, and very wrong in a few)
- In the FIFO case the array is now averaged and published in `sensor_gyro` for filtering downstream. I'll update this in the future to use the full FIFO array (if available), but right now it should be fine.
- 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
- this provides some extra space when the FIFO transfers don't align perfectly
- I've also made an effort to keep the different drivers (icm20602, icm20608g, ism330ldc) in sync so we can factor out the common portions later once we've confident in the pattern.
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)
- fixed df_ltc2946_wrapper battery dependency
- fixed px4::atomic fetch_add for QuRT
- updated PX4 QuRT SPI wrapper to set bus frequency
- renamed "qurt-default" configs to just "qurt"
* NotchFilter: add NotchFilter template and test for float type
* NotchFilterTest: add test for Vector3f notch filter
* PX4Gyroscope: add notch filter with IMU_GYRO_NF_(FREQ|BW) parameters to
set the notch center frequency and bandwidth
- deprecate DriverFramework bmp280 driver (df_bmp280_wrapper)
- update beaglebone blue and snapdragon flight eagle boards to use in tree bmp280
- update posix (really just linux) and qurt I2C wrappers
- tested on beaglebone blue
