Adding a 640x480 camera to your Zedboard

Hi all.

I've adapted a low-cost VGA camera module to interface with the Zedboard over PMODA and PMODB. About $15 worth of hardware and no soldering to give your Zedboard eyes!

As the PL has four PMODs you should even be able to give it stereo vision.

It is currently showing a picture on the Zedboards Analogue VGA out, but I want to test and polish it just a little more before I release the code - tweak some of the camera's registers values and so on.

I've added a community project, and will put the code up as soon it is ready. If in the short term you would like the code, just email or message me.

Kind regards

Mike

Are you also developing a module to transfer the image to DDR memory via AXI HP ?

The project is pretty much complete - I would like to add a way to store the image in the DDR memory, but that is beyond my skills at the moment.

I've also discovered that the cameras I am using do not have infra-red filters, so the colours are all mixed up.

Also, although the cameras are 640x480 on a 25MHz clock they are only 30 frames per second, as a pixel requires two clocks to transfer.

Chris put in the time to work out what was wrong with the colours, and has produced an excellent result (see sample on project page at http://hamsterworks.co.nz/mediawiki/index.php/Zedboard_OV7670).

I'll updated the project archive as soon as I get a chance, but for now the updated source is available on the page too.

I've made a little PCB to mate the camera module to the PMODs. The minimum order was 10, so I have a few left over. If you would like the bare PCB send me an email (hamster at snap dot net dot nz).

If you want I can also send you the design files - it cost me US$15 to get 10 PCBs made.

I would like to, but I don't really have the time/need to build the skills required to store the frame buffer in DDR memory...

Maybe one day when I have more time on my hands!
