Detailed Description

Standard Digital Camera Control Interface.

-Standard IO -I2C Control

Usage: (from the flight plan, the settings or any airborne code):

  • dc_send_command( )
  • set the appropriate autoshoot mode (off/time/distance/trigger)
  • use the module periodic function to set the autorepeat interval
  • define SENSOR_SYNC_SEND to get the DC_SHOT_MESSAGE on every SHOOT command

Function Documentation

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
intervalminimum angle between shots in deg
startreference course in deg (or special DC_IGNORE)
Returns
zero

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
intervalminimum distance between shots in m
Returns
zero

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
intervaldistance between shots in meters
xx coordinate of reference point (or special DC_IGNORE)
yy coordinate of reference point (or special DC_IGNORE)
Returns
zero
