Instruction manual

DESCRIPTION: Sets the desired exposure time in micro seconds. For some cameras not all values can
be realised. In these cases the function sets the exposure time to the next possible value. The realized
and the desired values can be obtained with el_GetExposureTime. For cameras which do not use the
clock, generated on the board, the use of el_SetPixelClock is still necessary because the values set there
are used for the timing calculations.
RETURN VALUE:
0 if OK
-1 if ERROR. See el_GetErrorCode for details.

PARAMETERS:
BoardId : board ID returned by el_OpenHW
FrameTrigger : mode of frame trigger, see below for list
LineTrigger : mode of line trigger, see below for list
DESCRIPTION: Sets the line and the frame trigger to one of the following modes:
RETURN VALUE:
0 if OK
-1 if ERROR. See el_GetErrorCode for details.
AUTOTRIGGER:
grabber waits for no signal at the end of a line/frame.
EXTERNALTRIGGER:
Grabber waits at the end of a line/frame for an external signal. If frame and line trigger are set to
EXTERNALTRIGGER the line trigger event is taken from the OPTO_2 input and the frame trigger can be
selected by el_SetExtTriggerInput . If for one of the triggers ( frame or line) AUTOTRIGGER is selected
the other trigger can be selected without restriction. E.g. if the frame trigger runs in AUTOTRIGGER mode
the line trigger is no longer restricted to OPTO_2.
