- use mixer for the simulation to the sitl mixer dir
- do not use virtual elevator in the mixer for the real vehicle

- P and D gains are too high for a racer
- default I gain is too low (0.25 is still quite low)
- use the thrust curve param instead of TPA
- improve responsiveness in Manual & increase max tilt angle to 60 degrees
- enable one-shot
- enable high-rate logging profile
- disable RC filter
When SYS_USE_IO was disabled, px4io would not start and thus there was no
RC. SYS_USE_IO=0 is interesting on Quads to avoid the IO and reduce output
latency.
Tested on Pixhawk 1 and Pixhawk 4
Flight tested: ekf2 w/ mag and compass by @nathantsoi: https://logs.px4.io/plot_app?log=79b81031-cf1e-41f0-890b-d6cd7d559766
NOTE: external I2C devices need a pullup. I have tested with a 3.3v 2.2k pullup.
Working:
- mpu6000, bench tested and verified via nsh
- fmu
- all 6 ch output bench tested w/ pwm and oneshot via nsh
- ppm input bench tested
- dsm input bench tested
- bmp280, bench tested and verified via nsh
- hmc5883, bench tested and verified via nsh, but requires an external i2c pullup
- gps on uart6
- startuplog, nsh, mavlink on uart4, but params are not sent for some reason. RSSI pin is TX, MOTOR 5 is RX (normal mode, 57600 baud)
- rgbled over i2c, bench tested and workingp
- sbus via the shared sbus/ppm pin (which includes an inverter to the mcu SBUS in pin), remove the solder bridge or jumper to the ppm pin before use
Not yet implemented:
- ADC
- OSD: passthrough video is untested, use at your own risk until a basic driver is implemented.
* Lists ROMFS files explicity instead of using GLOB_RECURSE
Previously, when ROMFS files that were not airframes were touched, the ROMFS
would not be rebuilt. The ROMFS files are now specified explicityl in a
CMakeLists.txt file that is located in the root ROMFS directory.
Now when one of the ROMFS files is touched the whole ROMFS is rebuilt.
When new files are added to the ROMFS, they need to be explicity added to
the CMakeLists in the ROMFS root directory.
* ROMFS: adds individual CMakeLists files in each subdirectory
Also moves the temporary ROMFS build directory to ${PX4_BINARY_DIR}/ROMFS/genromfs
so that the cmake_install.cmake files and the CMakeFiles directories (generated whenever
are not add_subdirectory() is called) are not generated in the temporary ROMFS directory
from which the ROMFS binary is created.
* cmake ROMFS generate add px4_add_romfs_files function
* ROMFS CMakeLists: adds explanatory comment to px4_add_romfs_files function
* ROMFS CMakeLists: updates copyright headers
- need to make some flash space for fmuv2 to avoid user confusion about
why it wind estimator only runs on some platforms

- increase the minimum pwm value for multirotor mode since we experienced
the rear motor stalling in certain situations when throttle was low
Signed-off-by: Roman <bapstroman@gmail.com>
Because the parameter does not make sense from a control theory
perspective. Either you have a gain with the unit 1/s or an inverse
gain or time constant with the unit s. But the time constant parameter
was neither bound to any exact unit nor did it apply instead of a gain.
Rather it adjusted multiple gains from rate and attitude control
according to an arbitrary scale. This can only by accident lead to
good tuning.
- this makes sure that all motors are idling in mc mode. having this too
low can lead to a motor stopping in flight which is critical for
attitude control
- experienced loss of attitude control in RTL during descent prior to this
change

- move to ModuleBase
- strip down to PWM 8 and 16 modes only
- remove all dead code
- implement missing pwm ioctls (current value, rates, etc)
- default rate 50Hz -> 400Hz
- simulated tailsitter needs a virtual elevator since we cannot simulate
elevons yet (liftDrag plugin does not model longitudinal moment Cm)
