Instead of requiring every program to specify the HAL related modules,
let the build system do it (in practice everything we compiled depended
on HAL anyway). This allow including only the necessary files in the
compilation.
The switching between different AP_HAL was happening by giving different
definitions of AP_HAL_BOARD_DRIVER, and the programs would use it to
instantiate.
A program or library code would have to explicitly include (and depend)
on the concrete implementation of the HAL, even when using it only via
interface.
The proposed change move this dependency to be link time. There is a
AP_HAL::get_HAL() function that is used by the client code. Each
implementation of HAL provides its own definition of this function,
returning the appropriate concrete instance.
Since this replaces the job of AP_HAL_BOARD_DRIVER, the definition was
removed.
The static variables for PX4 and VRBRAIN were named differently to avoid
shadowing the extern symbol 'hal'.
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
reading
when aborting a landing via mode change, check if NAV_CONTINUE_AND_CHANGE_ALT is after LAND. If so, go ahead and execute it. Else, normal behavior or check do_land_start else decrement mission index
- previously we only kept track of starting flying while in auto which gets reset when switching in and out of auto and on takeoff/land. Now we keep track of a "global" one that will track the is_flying flag regardless of the flight mode.
fixes https://github.com/diydrones/ardupilot/issues/2778
When executing a takeoff, and the throttle is suppressed, but we're already flying, we should unsuppress the throttle. We can get into this situation if we reset the mission in-flight.
- 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
