Hello,

I am working on a project that requires me to retrieve the pixel information from the ov2640 camera on the eval2 board.  I am not really sure how to do this and I was wondering if anybody had any advice on this topic that can lead me in the right direction.

You'd have to look at the memory buffer the DCMI has copied it's data stream into, and the colour/stream format the camera has been configured to generate.

The bitmap data you get is going to be a rastered version of the captured stream (line after line, top to bottom), and you'd presumably index into it using a simple row/column methods
