			* You can then use Armadeus "capture" demo tool to get images from the camera.
			* First time you will have to set the camera module registers correctly (not done by the driver yet) by using a custom script ov9655_regs.sh available [ here]. Here is how to proceed:
			<pre class="apf">
			# capture & usleep 400000 ; ./ov9655_regs.sh

Even if you find some datasheet, the informations inside must be read with caution: some are erronous.
