this is an unusual option that gives FBWA flight control in AUTO
mode. It is being added to support use of APM in an aerial robotics
competition where students need to pilot the plane, but they still
need waypoint triggering of payloads
this switches ArduPlane over to use the L1 navigation controller, via
a generic nav_controller object pointer.
Note that the nav_controller controls all types of navigation now,
including level flight and heading hold. This provides a cleaner
abstraction than the old method of special case navigation handling

this makes FBWB much less sensitive to airframe tuning. When the
elevator stick first goes neutral it locks in the current altitude as
the target altitude. When the elevator stick is off neutral, it moves
the target altitude in proportion to the elevator, at a rate goverened
by the new FBWB_CLIMB_RATE parameter
This prevents the aircraft from slowly drifting in altitude in FBWB,
and gives a more intuitive control mechanism for altitude.
Thanks to Chris Miser from Falcon UAV for help in designing this
change
this allows control over whether ArduPlane tries to hold heading
during auto takeoff. For hand launches it can be better to hold the
wings level and not attempt to hold heading during takeoff to prevent
the possibility of a stall during the climb out.
Thanks to Chris Miser from Falcon UAV for the feedback that led to
this option.
this allows direct passthru of throttle in STABILIZE and FBWA, which
is useful for nitro planes wher you have a throttle cut switch that
drops the throttle below normal minimum.
sanity checking added to accelerometer calibration routine.
user feedback is sent using gcs_send_text_fmt instead of Serial.printf.
moved ins parameters to new eeprom number to avoid conflicts with older parameters.
other small changes including renaming of functions and parameters.
The nudge value depended on RC3_TRIM, which is not a reliable
value. It tried to only take effect when the throttle stick was above
50%, but if RC3_TRIM was high for some reason (say 1500) then it would
actually depress the throttle by a large amount, which could cause the
plane to stall.
This also adds a boolean option THROTTLE_NUDGE to allow disabling of
throttle nudging
this allows you to select different altitude control algorithms. The
current choices are for the default (automatic based on if airspeed is
available), or to force a non-airspeed algorithm
The idea is to make it possible to use airspeed for some things (like
wind speed, speed scaling) but not for alt control
when enabled this will use the wind estimation code to adjust the
navigation bearing, allowing the navigation code to cope with much
higher levels of wind while using a compass
this adds FS_* parameters for setting up APM to follow the outback
challenge failsafe rules.
This includes:
- manual pin
- heartbeat pin
- waypoint for heartbeat failure
- waypoint for GPS failure
this allows users to adjust the base speed used for scaling roll/pitch
PIDs. This can be used to make PIDs work for both airspeed and
non-airspeed control
this enables MNT_* parameter control of the camera mount code. It also
fixes the conversion of calculated angles between degrees and
integers, and fixes stabilised mount control when yaw control is not
available.
setting ARSPD_ENABLE to 1 and ARSPD_USE to 0 allows the airspeed
sensor to be initialised and logged without it being used for flight
control. This is very useful when initially testing an airspeed sensor
in a new plane. It also makes it possible to enable/disable the use of
the airspeed sensor during a flight at any time.
when MANUAL_LEVEL is set to 1, we don't do accelerometer levelling at
startup, and instead used the values saved in the EEPROM. This makes
it easier to do levelling on the bench, or once for a series of
flights for the day
Fixes compatibility for APM2. Also a significant update to the battery monitoring code: We previously had monitoring modes for individual cell voltages for 3 and 4 cell lipos. These have been removed as they were never really supported (the cell voltages were computed but were not reported or recorded anywhere). Also, some clean-up/prep work was done for supporting monitoring 2 separate battery packs. The CLI battery and current monitoring tests were consolidated into 1 test.
This is useful for switching back to the mode indicated by the control
switch after a failsafe or fence breach. I was just changing modes
each time, but it is far more elegant to have a spring loaded switch
for "I am ready to take control again", rather than continually
changing modes.
This patch will boost the target airspeed as necessary to keep the ground speed above a parameter value - param_min_groundspeed. Airspeed is still limited to FBW-max. Setting min_groundspeed to zero (default) disables the feature.
This commit is somewhat temporary as I have come up with a better scheme and will be modifying this. Just making this commit in case I need to roll back
