Gustavo Jose de Sousa b8e518a533 waf: use ap_library tool
That way we avoid recompiling source files that don't depend on vehicles.
Change notes:
- UTILITY_SOURCE_EXTS: moved to ap_library
- Task generators indexes: ap_library handles that now and in a better way
- Use of AP_STLIB_FEATURES: it doesn't make sense anymore, since the stlib
  taskgen has empty source list
- Flags and defines: passed down to ap_library through AP_LIBRARIES_OBJECTS_KW
- Set use='mavlink' in AP_LIBRARIES_OBJECTS_KW instead of calls to
  bld.ap_stlib().

Peter Barker f67d247a46 Copter: factor pre-arm checks, continue testing after a failure
The functional change here is that we continue to run later checks
when a check fails.

The user-visible effect of that is that your GCS will tell you about
all pre-arm failures, not just the first.

This makes things work a little more like Plane, in preparation for
using AP_Arming.

rangefinder shows an altitude below 2m

Andrew Tridgell e4564de837 Copter: fixed heli criterion for unsetting land_complete

Andrew Tridgell a67b9372fd Copter: check that climb rate is low in landing detector

and trigger the landing detector. See the log for Robs heli.

Randy Mackay 728e8f8f56 Copter: land_state uses enum

Randy Mackay 542677f1d5 Copter: land vertical control uses current_loc.alt instead of get_alt_cm
This resolves a warning from Covarity that we were not checking the return
value of Location_Class::get_alt_cm.  It was not actually a problem.
No functional change
2016-08-08 13:30:53 +09:00
Randy Mackay 3be76743bf Copter: precland checks get_alt_cm return value

Randy Mackay 68d3655195 Copter: fix rtl's use of rally point alt
Thanks to OXINARF for spotting this
2016-08-06 14:01:38 +09:00
Randy Mackay 57977e2d76 Copter: ensure RTL to rally point does not breach the altitude fence
Previously we added the rally-point altitude to the calculated return altitude on the final line of this function meaning the fence's altitude check was not performed on the final value.  This change adds the rally-point altitude as the first step so it is included before the fence altitude check.
This change also converts the return alt to an alt-above-home so that it can correctly be compared to the fence (previously a terrain-altitude might have been compared to an alt-above home)
2016-08-06 14:01:31 +09:00

Randy Mackay ac4f36a992 Copter: remove LAND_REQUIRE_MIN_THROTTLE_TO_DISARM feature
This definition has been false for over a year and we have not heard of any users wanting to delay the disarming until the pilot's throttle goes to zero.  Removing this feature removes a small bit of complexity from the code.

Randy Mackay 88da5bd453 Copter: sport mode restructured to match althold and feedback from mid-stick
This modifies sport mode to be structured like althold and loiter flight modes so that ongoing maintenance of the modes is hopefully easier.
Also changes throttle feedback to occur from mid-stick

This also adds a new parameter class ParametersG2 which can hold 64
parameters. This is to avoid running out of parameters in the first

Peter Barker 043b1d321d Copter: remove paths for documenation for non-multi frame
Our current documentation system only emits one XML document (apm.pdef.xml)
for ArduCopter.

Since there is a conflict between parameters in the MOT_ namespace in Copter,
we only emit the documentation for the first parameter defining the MOT_ namespace.

This patch removes the documentation lines for frame types other than multicopter, meaning the documentation will reflect mutlictopter usage - the most common case.

These lines will need to be reinstated when we change the way we produce the xml documentation.
