ARDUCAM Questions Timing

Hey,

i try to connect another camera to the arducam board. It is a 320x240 greyscale camera. The board works fine with the OV2640.

But when i connect my cam, i get an image as you see in the attachment. You see that i get a picture but only in 2 quarter in the bottom.

The difference between the cameras is the PCLK. The OV2640 has 20 mhz an my cam only 5 mhz. Could that be the reason ?

And how can i change this in the ARDUCHIP ?

Thanks for an answer with an idea…

yes, could be,

2 quarters, so the image is in 1 quarter, that is a factor x in height and a factor 2 in width, matches the factor 2x2=4 in clockspeed.
The colours might be a lookup error (uninitialized LookUpTable (LUT))

And how can i change this in the ARDUCHIP ?

no idea,
