Hello
I have ov7670, wifi shield with sd card, and arduino uno r3. I have read MR_Arduino's posts on ov7670 but I am still confused. Mr_Arduino doesn't use any arduino functions to capture an image from ov7670 and save to a sd card. can you use digital read/write or analogue read/write to capture an image and store it on a sd card? is there a ov7670 library for arduino that doesn't use a shield?
Thanks
