Sorry for the late reply, and thanks a lot Bob, I have the data sheet, and
I have try write up a SCCB verilog HDL program with the reference to
another of similar Omnivision product, the OV7720 camerachip's SCCB
program. But there are two questions I have in mind,

1. Is the SCCB.v program for the OV7720 camerachip will also work with
Ov9650 camerachip or does two program bear any similarity so that I could
refer to that?

2. When I have done the SCCB.v code, should I write another module to
initialize the camera with the settings I want? I found it hard to
understand the 2-phase write and read cycle...

I really need help to get this camera work by this week...Hope to get some
help from pros here! Thanks!

So you haven't started, yet?

If the 9650 data sheet says it uses the same SCCB protocol, then it
probably does.

Write another module or put it into the same module - organize your code
any way that you want.

I already suggested a course of action but you don't appear to have made
any progress in 2 months. good luck,
Bob
