Allows user to control whether nose points towards next waypoint and/or
home when RTLing.
Replaces YAW_OVR_BEHAVE which had a very similar purpose. Almost nobody
ever knew about or used this parameter.
loiter_time_max was changed to hold the loiter time in seconds
(previously it was milliseconds) in order to allow the delay to be more
than 65 seconds but the verify_loiter_time check was missed from that
change
RTL fix so that if it starts rtl-ing from above 80m it returns home
while descending instead of descending at initial position.
add get and set_target_alt_for_reporting
lon_speed, lat_speed changed to float
do_takeoff, do_land now set roll-pitch, yaw and nav modes specifically
removed fast_corners functionality (may need to be reimplemented with
new inertial nav controllers)
Renamed run_navigation_controllers() to run_autopilot()
Renamed update_nav_wp() to update_nav_mode()
Renamed wp_control to nav_mode to be more consistent with roll-pitch,
yaw and throttle controllers
- Allows use of hardware floating point on the Cortex-M4.
- Added "f" suffix to floating point literals.
- Call floating point versions of stdlib math functions.
Previously we checked if the alt > target_alt but because there is
little to no overshoot with the new accel based alt controller this
check was failing for some users.
Switch to LAND flight mode if throttle failsafe triggers and we do not have a GPS.
THR_FAILSAFE renamed to FS_THR_ENABLE.
THR_FS_VALUE renamed to FS_THR_VALUE.
THR_FS_ACTION removed (action is now controlled by setting FS_THR parameter).
Added set_yaw_mode to better control of yaw controller changes and variable initialisation.
Replaced AUTO_YAW mode with separate yaw controllers YAW_LOOK_AT_NEXT_WP, YAW_LOOK_AT_LOCATION, YAW_LOOK_AT_HEADING.
Pilot manual override of yaw causes yaw to change to YAW_HOLD (i.e. manual yaw) until next waypoint is reached.
Added get_yaw_slew function to control how quickly autopilot turns copter
Changed YAW_LOOK_AHEAD to use GPS heading and moved to new get_look_ahead_yaw function in Attitude.pde
Renamed variables: target_bearing->wp_bearing, original_target_bearing->original_wp_bearing.
Removed auto_yaw_tracking and auto_yaw variables and update_auto_yaw function as they are no longer needed.
Simplified MAV_CMD_CONDITION_YAW handling (do_yaw). We lose ability to control direction of turn and ability to do long panorama shots but it now works between waypoints and save 20bytes.
Consolidated RTL state to be captured by rtl_state variable.
Combined update_RTL_Nav and verify_RTL functions which performed the same function but one was for missions, the other for the RTL flight mode.
Renamed some RTL parameters and global variables to have RTL at the front.
Landing detector now checks accel-throttle's I term and/or a very low throttle value
Changes include:
New low-level get_throttle_accel function takes target acceleration and compares vs earth-frame Z accelerometer values to produce output to motors.
Higher level throttle controllers modified to call new get_throttle_accel controller
Throttle_rate_stabilized controller added which maintains a desired climb/descent rate
Throttle_land controller added - descends using normal auto throttle controller to 10m then descends at 50cm/s
Multiple throttle modes added including landing mode
Land flight mode no longer needs GPS
Throttle cruise maintenance moved to update_throttle_cruise function
