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.
* 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
- Startup was broken due to unnecessary cyclic check probably introduced during transition to work_queues
- Module never used other than on Teal One which had a hacky heater input GPIO, this enables usage on general boards
drivers: heater: reduce verbosity and simplify commandline options
- We prefer the linux way of only reporting errors and staying quiet when everything is functioning as designed
- Most of the commandline options just read out the values of the system parameters, and one can just check the parameter values directly.
sensor_params: make thermal control parameters system parameters
heater_params: make thermal control parameters system parameters
drivers: heater: remove pin control hacks
- px4_arch_configgpio(GPIO_HEATER_OUTPUT) directly inits the heater pin to OFF, and as a PUSHPULL (TTL totem pole) OUTPUT
drivers: heater: set default device ID to 0
A low gyro cutoff is needed for most medium/large size drones as the structural natural and blade-pass frequencies are low.
A higher value is still desirable for small platforms surch as racers
or well isolated autopilots and should be tuned by the user.
Specific values for config files are untouched.
The cutoff filter for the D term is disabled here as the required
cutoff frequency for the default D term of the rate controller is higher
than the gyro cutoff. In that case, enabling the D term cutoff would
just add some undesired phase lag to the derivative.
tested on at least 5 different vehicles, including AeroFC. The values
should be conservative, good setups (with low vibrations) can increase
these values even further.
increasing IMU_GYRO_CUTOFF allows for better tuning gains (increased P).
Update the model for the standard configuration based on the model from Sensirion and add also an option to do the tube pressure loss correction from Sensirion for other configurations.
This commit changes old trone driver into a generic
TeraRanger driver that supports both TeraRanger One
and TeraRanger Evo.
As a part of the change a new parameter was created
SENS_EN_TRANGER that allows to specify the following
modes of operation:
0 - sensors disabled
1 - autodetect sensors
2 - use TeraRanger One rangefinder
3 - use TeraRanger Evo rangefinder
