Controlling image capture
GUPPY Technical Manual V4.0.1

One-Shot
The camera can record an image by setting the one-shot bit in the 61Ch reg-
ister. This bit is automatically cleared after the image is captured. If the cam-
era is placed in Iso_Enable mode (see Chapter
ISO_Enable / Free-Run on page
135), this flag is ignored.
If one-shot mode is combined with the external trigger, the one-shot com-
mand is used to arm it. The following screenshot shows the sequence of com-
mands needed to put the camera into this mode. It enables the camera to
grab exactly one image with an external trigger edge.
If there is no trigger impulse after the camera has been armed, one-shot can
be cancelled by clearing the bit.
