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
@Description: X-Axis deceleration threshold to notify the crash detector that there was a possible impact which helps disarm the motor quickly after a crash. This value should be much higher than normal negative x-axis forces during normal flight, check flight log files to determine the average IMU.x values for your aircraft and motor type. Higher value means less sensative (triggers on higher impact). For electric planes that don't vibrate much during fight a value of 25 is good (that's about 2.5G). For petrol/nitro planes you'll want a higher value. Set to 0 to disable the collision detector.
- inhibit crash detection warnings when disabled by param so now it can be completely disabled
- reset is_crashed when disabled by param
- fixed pre-takeoff detection bug by adding in_preLaunch_flight_stage() where we are actually in FLIGHT_NORMAL instead of FLIGHT_TAKEOFF during setup of bungee launches. This now detects if we're in that state
- simplified the use of been_auto_flying to check across all flight stages. before it was excluded to handle hand-launches which can now be detected with in_preLaunch_flight_stage()
- added impact detector timer to clamp is_flying a few seconds after an impact
- logging new impact detector as "STAT.Hit"
- 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!
Most of AP_Progmem is already gone so we can stop including it in most
of the places. The only places that need it are the ones using
pgm_read_*() APIs.
In some cases the header needed to be added in the .cpp since it was
removed from the .h to reduce scope. In those cases the headers were
also reordered.
prog_char and prog_char_t are now the same as char on supported
platforms. So, just change all places that use them and prefer char
instead.
AVR-specific places were not changed.
Include board-specific files only when the board is used. Since these
should be exceptional cases, let the includer handle the ifdef instead
of putting ifdefs in every platform-specific header.
In the future we should evaluate whether the HAL for the board should
instantiate this.
we only accept a lidar if it changes by 5% of its full range, and we
reject a lidar again if the correction between barometric and lidar
range changes by more than 30m
This allows us to cope with faulty lidars which may give a constant
