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

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!

Do you have the full data sheet for the OV9650? After you sign their
NDA, OmniVision will send it to you. You'll also want to download the
SCCB spec, although it's a pretty simple 2 0r 3 wire serial protocol.

After you have the docs, I would suggest setting up an environment that
will allow you to easily change registers in the imager and display the
results. There are many, many registers in these things and I didn't
find it obvious which ones did what.
HTH,

Hi all. I have just purchased the omnivision 9650 cmos camera for my
project of image processing and i wish to interface the camera with the
Altera DE2 FPGA board. For this I need to write the configuration in
verilog code program but I do not have a clue about how to write it. Can
anyone here provide any guidance? Thanks a lot.
