View Full Version : Use GPIO as strobe / GPIO Latency

August 30, 2011, 04:40:18
Hi All,

I am currently trialling a DFK 22BUC03 which is a great little camera, especially for the price. Unfortunately it doesn't have a strobe output, which I require for my application, and the more expensive models which do have the strobe output, lack the FPS and sensitivity which the DFK 22BUC03 has.

My question is, does anyone know the speed/latency at which the GPIO can be used via the software?

For instance could I enabled the GPIO port to turn my lights on, perform my exposure, and then disable the GPIO?

Hello James,

the latency is unknown, because it also depends highly on the communication speed of the computer. The GP Out can not be synchronized with the exposure start of the camera.
