Video Starter Kit, LVDS Camera

I am trying to interface the LVDS Camera with the VIODC on the video starter kit.  I am basically trying to stream in data from the camera, store it in a frame buffer, and then display it on VGA.  The display portion of my design works fine.  I am having trouble getting the correct data from the camera.  I was wondering if anyone had detailed timing diagrams of the camera other than the ones that are including with the MT9V022 digital image sensor(the image sensor for the camera).  I need to know the relationship between the clock and the LVDS data signal.  I was also wondering if anyone has the correct register values for the MTV9022 digital image sensor that monochrome operation would work properly.  I have had a very difficult time finding the appropriate documentation for the camera and have tried to email Irvine Sensors (the manufacturer)

 

I have looked at the demo that is available but this was done using EDK and system generator.  I have done my design completely in Verilog.  I did find some initial register values for the camera in the Microblaze code but using these values did not seem to fix the problem.

 

Please help,

Jason

Also, I used a Picoblaze processor for my I2C initialization.

Re: Video Starter Kit, LVDS Camera

The relationship between the LVDS clock and the LVDS data is a bit vague.  In the end, I changed my interface to sweep the pahse shift of a DCM through the databit to find a good sample point instead.

 

We'll have an IP core of this interface available soon...

 

Cheers,
Martin
