AravisCameraset_trigger

since: 0.8.0

Declaration [src]

void
arv_camera_set_trigger (
  ArvCamera* camera,
  const char* source,
  GError** error
)

Description [src]

Configures the camera in trigger mode. Typical values for source are “Line1” or “Line2”. See the camera documentation for the allowed values. Source can also be “Software”. In this case, an acquisition is triggered by a call to arv_camera_software_trigger().

The trigger set is “FrameStart”. “AcquisitionStart” is used as a fallback if “FrameStart” is not present. All other triggers are disabled. “TriggerActivation” is set to rising edge.

For an advanced trigger configuration, use the underlying ArvDevice object returned by arv_camera_get_device().

Available since: 0.8.0

Parameters

source

Type: const char*

Trigger source as string.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
