I need a card that will compare each frame and send me only the pixels that changed. This is used with a fixed camera position. There would have to be a simple threshold and a hopefully a way to reduce resolution. I don’t care about color or intensity but that probably be available in the design. I’m not clear on this, can this be programmed into the card?
It would be challenging to do what you propose on an Arduino. There is only 2K of memory, and that’s why Arduino video is limited to very low resolution. Since you need two frame buffers to compare, you’d be at even lower resolution. No color info is available using the Video Experimenter.
Any chance your video shield will eventually work with the Uno32 or the Uno32 will eventually work with your video shield?
Regarding the chipKIT UNO32, nope, not a chance. The pin assignments on the UNO32 are all different. And the UNO32 is 3.3V, so you can’t use shields that have 5V CMOS chips.
