It makes sense to consider also other floating point types.
2016-05-10 11:41:26 -03:00
dgrat 41661f815f AP_Math: Replace the pythagorous* functions with a variadic template
The new function can deal with a variable number of function parameters.
Additionally, I renamed the functions to norm(), because this is the
standard name used in several other projects.

Lucas De Marchi 2591261af6 Global: rename min and max macros to uppercase
The problem with using min() and max() is that they conflict with some
C++ headers. Name the macros in uppercase instead. We may go case by
case later converting them to be typesafe.

Lucas De Marchi 831d8acca5 Remove use of PROGMEM
Now variables don't have to be declared with PROGMEM anymore, so remove
them. This was automated with:

    git grep -l -z PROGMEM | xargs -0 sed -i 's/ PROGMEM / /g'
    git grep -l -z PROGMEM | xargs -0 sed -i 's/PROGMEM//g'

The 2 commands were done so we don't leave behind spurious spaces.

AVR-specific places were not changed.

Gustavo Jose de Sousa ee2c388bb0 AC_WPNav: standardize inclusion of libaries headers
This commit changes the way libraries headers are included in source files:

 - If the header is in the same directory the source belongs to, so the
 notation '#include ""' is used with the path relative to the directory
 containing the source.

 - If the header is outside the directory containing the source, then we use
 the notation '#include <>' with the path relative to libraries folder.

Some of the advantages of such approach:

 - Only one search path for libraries headers.

 - OSs like Windows may have a better lookup time.

Randy Mackay a2f54fdf2c AC_WPNav: smooth waypoint by freezing feed-forward and allowing overshoot
First part of this fix is freezing the position controller's xy-axis
feed foward as we transition to the new segment.
Second part is work-around for straight line segments in that we allow
the target point to actually overshoot the end of the segment by up to
2m if the segment is a "fast waypoint".  Ideally we would instead notice
the waypoint has been completed and take any left over time or distance
and move our target along the track towards the next waypoint but that
would require a much larger change to allow the wpnav lib to hold the
next two waypoints.

Randy Mackay ce85d1f6b2 AC_WPNav: use curr pos target as spline origin
We only use the current target position as origin if the waypoint

Randy Mackay e7b3c00767 AC_WPNav: set_loiter_target uses set_xy_target
Loiter is only a horizontal position controller so it should not set the
z-axis position.

init_loiter_targets function order
2014-05-19 12:27:20 +09:00
Ju1ien aed5787c1b AC_WPNav: bug fix for loiter init in Hybrid
AC_PosControl::init_xy_controller() has been added to PosControl and is
called by init_loiter_target.
Hybrid is currently using set_loiter_target function to init the loiter
controller. So we have to call init_xy_controller() by set_loiter_target
function.
What happens otherwise?
In AC_PosControl::update_xy_controller, we update "now" with
now = hal.scheduler->millis();
and, as _last_update_xy_ms has not been updated previously by
init_xy_controller(), we just call init_xy_controller().
So, _dt_xy  will be negative and used anyways in all the functions and
PID called by update_xy_controller.
That will avoid at least _accel_target.x/y to be set to 0 but I'm not
sure for the high values, probably an I_term that is not reset and
reached very high value.
Or maybe a cast error somewhere... no clue at all
