I would like to create a simple frame synchronihed stereo camera. I found there are cheap OV7670 boards (without FIFO memory) that work with Arduino (or compatible) boards - these sensors do not have an oscillator on board and accept external clock signal. The basic idea is to feed both cameras with a common clock signal.
The cameras are controlled via I2C interfaces where the resolution, image format etc. are being set. I think there may also be a need to configure both sensors at exactly the same time since the change of resolution/framerate will most likely affect the synchronization. This may lead to the requirement of two separate I2C buses that are able to issue a command exactly at the same time.
Could someone prove my assumptions right or wrong please? And possibly direct me to hardware capable of doing the parallel I2C stuff I need? Thanks.
