Function Documentation

◆ dc_circle()

uint8_t dc_circle	(	float	interval,
		float	start
	)

Sets the dc control in circle mode.

In this mode the dc control assumes a perfect circular course.

The 'start' value is the reference course and 'interval' the minimum angle between shots. If 'start' is DC_IGNORE the current course is used instead.

The first picture is taken at angle start+interval.

Parameters

interval	minimum angle between shots in deg
start	reference course in deg (or special DC_IGNORE)

Returns: zero

◆ dc_distance()

uint8_t dc_distance ( float interval )

Sets the dc control in distance mode.

Shoot the next pic if distance to last saved shot position is greater than interval.

The first picture is taken at after interval.

Parameters

interval minimum distance between shots in m

Returns: zero

Here is the caller graph for this function:

◆ dc_survey()

uint8_t dc_survey	(	float	interval,
		float	x,
		float	y
	)

Sets the dc control in distance mode.

In this mode, the dc control assumes a perfect line formed course since the distance is calculated relative to the first given point of reference. So not usable for circles or other comparable shapes.

The values of 'x' and 'y' are the coordinates of the reference point used for the distance calculations. If 'y' is DC_IGNORE the value of 'x' is interpreted as index of a waypoint declared in the flight plan. If both 'x' and 'y' are DC_IGNORE the current position will be used as reference point.

Parameters

interval	distance between shots in meters
x	x coordinate of reference point (or special DC_IGNORE)
y	y coordinate of reference point (or special DC_IGNORE)
