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.
new params LAND_PF_ALT, LAND_PF_SEC, LAND_PF_ARSPD, USE_REV_THRUST
Added update_trigger and check_digital_pin functions
added camera trigger precise time mark
detect camera feedback pin status
added support for simple digital pin
included support for digital pin. Already included in
added support for TRIGGER MSG
- 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
- allow rangefinder to power-off using baro if terrain data not available
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
