OV7670 I2C read and write registers

Hi,

Could I please ask anyone who has a MEGA ( or DUE) that can successfully read and write
to OV7670 registers to post their code and describe any wiring?

I have had little success with all the OV7670 examples on various sites ( fuyuno, XNplater, mariachi etc etc). I am very sure I have h/w ok and checked out with an oscilloscope, but I just never get a response.

I either get a '2' with IC scanner or a '255' from reading a register (by commenting out the wait for byte) in fact its a no response.

I am beginning to think my camera module is suspect.

Thanks
