    Hi, I'm workong on the interface between an Atmega16 and I would like some help with the same.

    Details:
    The sensor I'm using is a sparkfun CMOS camera (http://www.sparkfun.com/products/637). Also, I will not be able to get another camera as this one has been already bought and I don't have enough budget.

    I am running the camera with an ~14Mhz crystal connected to the clock generator and All I am interested in doing is taking a 176x144 pixel image into the microcontroller and outputting it to matlab using serial.

    For everyone who says it's not possible, it has been done before.

    The problem: after supplying the required signalling, I am unable to get a output clock on the PCLK pin (which seems to stay inherently high) and HSYNC and VSYNC are always low.

    I just hope someone is able to help.

    Thanks!
