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
get_throttle_althold_with_slew's target_alt parameter defined as int16_t
(instead of int32_t) meaning missions with altitudes >320m could wrap
around and become negative.
- 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.
new set_accel_throttle_I_from_pilot_throttle function copies the
difference between the pilot's throttle and hover throttle to the
accelerometer based throttle controller's I term.
Improved surface tracking by using slewed althold controller
Reduced sonar mode filter to just 3 elements to reduce lag but at the possible consequence of allowing sonar noise to creep through for people with margin sonar set-ups.
get_throttle_rate_stabilized changed to simply update the target altitude instead of talking directly to the rate controller.
get_throttle_althold changed to use sqrt of distance when calculating the desired rate towards the target altitude.
added reset of accel based throttle PID's I term.
unrelated small bug fix from Randy to allow CH6 tuning of throttle rate D term.
Also removed slow low pass filter meant to correct for accelerometer calibration. This is no longer required now that we have the improved calibration method.
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
