low power mode (snapshot) on OV2640

Question asked by kilshtein.daniel on Mar 17, 2013

I'm working on a project where power consumption is a critical issue. I need to store a frame from a camera (OV2640) on the uSD each 2 seconds. My problem is that the camera's clock is always on which bring the power it uses to a maximum.

I read in the datasheet (OV2640_spec.pdf) about an IO (pin A2 and register 0x0c) which provides some sort of a trigger but till now, I failed to switch to the low power (I need some sort of a snapshot mode). Does anyone know how to set the camera to a low power mode? Is there a register I can write to?
