5. Transmit images off of the camera
The final step involves setting One Shot/Multi-shot in order to cause the camera to transmit one or more images
from the frame buffer over the data interface.
Although it is possible to repeatedly transmit the same image, there is no way to access images that are older than the
last image transmitted.
Whether by enabling trigger or disabling isochronous data, switching out of a free running mode leaves the last image
transmitted in an undefined state.
The frame buffer is volatile memory that is erased after power cycling. To store images on the camera after power
cycling, use Non-Volatile Flash
and storage is limited.
To control frame buffer:

Camera Firmware

Firmware is programming that is inserted into the programmable read-only memory (programmable ROM) of most
Point Grey cameras. Firmware is created and tested like software. When ready, it can be distributed like other software
and installed in the programmable read-only memory by the user.
The latest firmware versions often include significant bug fixes and feature enhancements. To determine the changes
made in a specific firmware version, consult the Release Notes.
Firmware is identified by a version number, a build date, and a description.
