All of the example wiring diagrams I have found seem to want to make use of GPIO pins rather than the dedicated SPI pins found on the 12E. The arducam mini that I've been considering appears to use a standard SPI pinout. Can anyone point me to a project that connects these two devices via SPI?

If that configuration is not possible, could you please tell me why, and maybe suggest another camera that could be used? My requirements are pretty light -- I only need 640x480 video (a widescreen format of something like 640x320 would be ideal) at a low frame rate that I could stream to a web page.

Isn't it funny when you find your own post later down the road? Figured I might as well provide the answer since I really hate finding unanswered posts when searching for something...

It turns out that those pins along the back side of the -12 models are dedicated to the internal flash memory. Even though many of the SPI lines are supposed to be shared between multiple devices, you can't actually do that with these lines. Your best bet is to completely forget about those pins along the back and pretend they don't exist (unless you plan on adding your own storage space). Unfortunately this means a device like the arducam is going to take up more than half your available I/O ports. Lucky for us the -32S has been released and should soon be widely available for larger projects...
