7.1.2
Standard External Trigger (Mode 0)
Trigger Mode 0 is best described as the standard external trigger mode. When the camera is put into Trigger Mode 0,
the camera starts integration of the incoming light from external trigger input falling/rising edge. The Exposure Time
describes integration time. No parameter is required. The camera can be triggered in this mode by using the GPIO pins
as external trigger or by using a software trigger.
It is not possible to trigger the camera at full frame rate using Trigger Mode 0; however, this is possible using
Overlapped Exposure Readout Trigger (Mode 14)
.
