ok...so.. it is not possible to connect the OV7670 module directly to the Arduino Board... it needs the ArduCAM module...
is it?.. :.
It seems to me by examining the arduCam shield that it's simply using either an ARM processor, FIFO memory or both to simply buffer the image data, then send it via SPI to the arduino. so it appears that it 'should' be able to connect the camera directly without the shield. I've looked thru all of the arducam library code looking for hints of what arduino pins are used for the mega boards but didn't find any defines or pin configuration. I want to try this library first, but was wanting to know if ANYONE knows how to connect the camera module directly to the arduino mega pins. A wiring diagram would be even better. I plan on driving the camera's XCLK pin with a 16mhz crystal. also I read on several forums something about using pullup resistors on the SPI or MOSI/MISO pins but not sure why. is there any info or advice on this matter? any help would be appreciated and I would be happy to share my results if I get it working
