Hi there!
So I've been trying to get data from my ov7670 and get strange results.
I'm assuming the d(0-7) pins represent the appropriate bit in a byte (e.g. d2 is bit 2), is that correct?
I attached an interupt to the href and either get all 1s or all 0s and blocking the lennse or turning on a light makes no difference.
I know the camera is working because I found I was getting a regular signal from the href and vsynch pins. I haven't used pull up resistors for href, vsynch, d(0-7) pins, pwdn or reset. Does anyone know how to fix the problem?
