Hello! I'm trying to interface between the OV7670 camera and Arduino Due. I've tried several times and cannot recognize the device on the I2C scanner.
There is only one diagram I found floating around (see attachment). This diagram is missing the HREF pin. At first, I thought it must be correct, but now I think the HREF pin is required. See this link with the VGA description: Digital Camera Project (dejazzer.com). All the wiring diagrams for Arduino Uno show this HREF pin wired to the D8 pin on the Uno.
Does anyone have any thoughts on the matter? Or, better, can anyone confirm if the attached wiring diagram is correct or not?
