Plane supports being armed, in takeoff logic and not spinning the motor
until the moment the safety button has been pressed. Unfortunately
because the safety button is required to be pressed for soft arming this
results in the plane updating home position while the user moves the
vehicle or is holding it to throw the vehicle which will can result in
several meters of altitude error from where the user expected home to
be.
Because the normal approach to plane is to have activated the safety
button before arming the aircraft this is not expected to be a behaviour
change for most users, but an improvement for people who use the button
to initiate a takeoff.
when Q_RTL_MODE=1 in a quadplane use RTL_RADIUS as the distance to
switch to QRTL mode. We navigate to the destination using direct
waypoint navigation instead of using a loiter circle.
some people connect USB to allow connections from a companion
computer. The arming check is sufficient to prevent unwanted battery
failsafes when bench testing
the nav controller can think we have already reached the loiter target
if we were last in a LOITER when we switch to RTL. In that case it
would switch to QRTL immediately

this allows the user to control tailsitters either in body frame (like
a plane) or in earth frame (like a multicopter). This is useful for
people wanting to learn to fly prop-hang on 3D planes
Removes the need for plane to do the math for finding the relative height.
Also caches the value at the same time we update current_loc, which is a
non behaviour change as that was the only time you could see a change in
the relative height propegate through the system anyways
this will reduce confusion when searching for FLIGHT_LAND_* and you get a bunch of takeoff related hits. It will also make more sense when the landing library fully manages the FLIGHT_LAND stage entirely because it will not mange FLIGHT_LAND_ABORT
- move functions restart_landing_sequence() and jump_to_landing_sequence() to AP_Landing
- NOTE: jump_to function can not set mode, so it is now done externally in vehicle
Moved the code theat updates the home position while the aircraft is
unarmed from 10hz loop to one second loop and ensured that is does not
update more then once every 5 seconds. Closes issue 4311.
Further to refactor of RC_Channel class which included
adding get_xx set_xx methods, change reads and writes to the public members
to calls to get and set functionsss
old public member(int16_t) get function -> int16_t set function (int16_t)
(expression where c is an object of type RC_Channel)
c.radio_in c.get_radio_in() c.set_radio_in(v)
c.control_in c.get_control_in() c.set_control_in(v)
c.servo_out c.get_servo_out() c.set_servo_out(v)
c.pwm_out c.get_pwm_out() // use existing
c.radio_out c.get_radio_out() c.set_radio_out(v)
c.radio_max c.get_radio_max() c.set_radio_max(v)
c.radio_min c.get_radio_min() c.set_radio_min(v)
c.radio_trim c.get_radio_trim() c.set_radio_trim(v);
c.min_max_configured() // return true if min and max are configured
Because data members of RC_Channels are now private and so cannot be written directly
some overloads are provided in the Plane classes to provide the old functionality
new overload Plane::stick_mix_channel(RC_Channel *channel)
which forwards to the previously existing
void stick_mix_channel(RC_Channel *channel, int16_t &servo_out);
new overload Plane::channel_output_mixer(Rc_Channel* , RC_Channel*)const
which forwards to
(uint8_t mixing_type, int16_t & chan1, int16_t & chan2)const;
Rename functions
RC_Channel_aux::set_radio_trim(Aux_servo_function_t function)
to RC_Channel_aux::set_trim_to_radio_in_for(Aux_servo_function_t function)
RC_Channel_aux::set_servo_out(Aux_servo_function_t function, int16_t value)
to RC_Channel_aux::set_servo_out_for(Aux_servo_function_t function, int16_t value)
Rationale:
RC_Channel is a complicated class, which combines
several functionalities dealing with stick inputs
in pwm and logical units, logical and actual actuator
outputs, unit conversion etc, etc
The intent of this PR is to clarify existing use of
the class. At the basic level it should now be possible
to grep all places where private variable is set by
searching for the set_xx function.
(The wider purpose is to provide a more generic and
logically simpler method of output mixing. This is a small step)
Ran into a bug on our physical plane where failsafe.last_valid_rc_ms was not recognizing that the transmitter had failed. This is likely due to how the standard failsafe works in receiving lower-than-possible throttle values. So in order to account for this, I added a new variable to the failsafe, AFS_last_valid_rc_ms, and I update it only if the ch3_failsafe (the throttle failsafe) is not on. If the throttle failsafe is on, that means that the plane has indeed lost transmitter input, so the AFS needs to recognize that.
@Description: This parameter reduces the pitch minimum limit of an auto-takeoff just a few seconds before it reaches the target altitude. This reduces overshoot by allowing the flight controller to start leveling off a few seconds before reaching the target height. When set to zero, the mission pitch min is enforced all the way to and through the target altitude, otherwise the pitch min slowly reduces to zero in the final segment. This is the pitch_min, not the demand. The flight controller should still be commanding to gain altitude to finish the takeoff but with this param it is not forcing it higher than it wants to be. (+1 squashed commits)
the glide_slope gets calculated every time there's a major event such as mission item change or wp_proportion change so its good to update the flight stage then too because.
also logging stage when stage changes, might as well get an extra data point in there when it's timely
// @Description: When zero, the flare sink rate (TECS_LAND_SINK) is a fixed sink demand. With this enabled the flare sinkrate will increase/decrease the flare sink demand as you get further beyond the LAND waypoint. Has no effect before the waypoint. This value is added to TECS_LAND_SINK proportional to distance traveled after wp. With an increasing sink rate you can still land in a given distance if you're traveling too fast and cruise passed the land point. A positive value will force the plane to land sooner proportional to distance passed land point. A negative number will tell the plane to slowly climb allowing for a pitched-up stall landing. Recommend 0.2 as initial value.
Reverse thrust for controlled landings, even with much steeper approach slopes. This is achieved by allowing throttle demand to go negative to maintain a target airspeed. A Pre-Flare stage was added, triggered by an altitude, to allow for a slower airspeed just before land. That lower airspeed can be near stall.

- parse MAVLINK_MSG_ADSB_VEHICLE msg
- new 1Hz adsb_update task to compare list against for threat detection
- perform object avoidance via loiter or loiter_and_descend. More methods are welcome!
- moved terrain alt rangefinder power-off trigger from trerrain thread to rangefinder thread

Remove the checks for HAL_CPU_CLASS > HAL_CPU_CLASS_16 and
HAL_CPU_CLASS >= HAL_CPU_CLASS_75. Corresponding dead code will be
removed on separate commits.
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:
git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'
The 2 commands were done so we don't leave behind spurious spaces.
AVR-specific places were not changed.
The PSTR is already define as a NOP for all supported platforms. It's
only needed for AVR so here we remove all the uses throughout the
codebase.
This was automated with a simple python script so it also converts
places which spans to multiple lines, removing the matching parentheses.
AVR-specific places were not changed.
- inhibit switching from FLIGHT_NORMAL to FLIGHT_LAND_APPROACH until we meet stricter criteria other than just that LAND is next waypoint
- requires: nav bearing error < 10deg && have traveled path forward 30% of path && are below top of approach in case we hit waypoint while still descending
- exceptions: traveled path forward > 80% which basically means we're getting close to the flare point and better get into approach mode ASAP
- enabled via new param LAND_ABORT_THR default is 0 (disabled)
- Triggered via 95% throttle during landing, a landing abort will take place.
- This copies all takeoff params for right now, we can make this better later if needed
- added mission item command to NAV_LAND which is the abort takeoff altitude. If 0 then use last takeoff if available, else use 30m
- hold heading, just like takeoff, until altitude is reached
- pitch is constrained to takeoff pitch, or else 10deg if not available
- After abort altitude is reached, the normal landing restart happens (DO_LAND_START or decrement mission)
- restart landing by jumping to DO_LAND_START or decrement mission on mode change
Use waypoint bearing if available, otherwise use gps projected ahead 1km else yaw
Perform update before making decision to finish cmd so it always executes
We don't need those comments anymore, now that we log the task name. Also,
keeping the comments means that we need to fix them when tasks are added in the
middle, not to mention the problem with tasks that are added selectively (i.e.,
guarded by preprocessor directives).
* Retains ability to read from Analog Pin
* Adds ability to read RSSI from PWM channel value as is done in OpenLRSng, EazyUHF, and various other LRS.
* Handles any type of RSSI that provides RSSI values inverted - i.e. when the low value is the best signal and the high value is the worst signal.
* Has different key names from all existing RSSI parameters to provide for a clean break and easier distinguishing.
* Existing parameters are marked as obsolete
add crash detection, allow disengage via param CRASH_DETECT
improved is_flying behavior
take off, landing and hard-landing improvements
add stillness check to is_flying and log it
minimum airspeed is determined ARSPD_FBW_MIN*0.75
setup the MODESWITCH channel as our OVERRIDE_CHAN, allowing for
instant manual passthru in px4io when OVERRIDE_CHAN goes above 1750
This makes for faster switching, and avoids bugs where a still enabled
FMU channel disables override
