I want to connect a camera to the atmega128 but i dont know what
should i do? and what kind of camera i must to use? please help me
it's very important for me .
thank you

I think we need more information than what you've given. What are you
trying to accomplish? Why do you want to connect a camera to an AVR? What
do you want it to do?

As Zach said, more information is needed on what it is you want to
do. "Camera" could be a lot of different things from a cheap web cam
to a high resolution digitial camera to camcorder or other motion
(e.g. security) camera.

If you want to simply have a camera hooked up and the AVR does nothing
more than command the camera to take photos, you might look into
earlier Digital still cameras with older RS-232 serial ports. These
are easily interfaced to an AVR and certain models used a chipset that
you can find the control codes for on the internet (Olympus cameras
for example).

Hi everybody and thank you for your messages
I want to make a system for door bells .
this system take's a picture from caller and save it to an EEPROM and show it to owner of a house.
now what do you think? what kind of camera i must to use? help me please
thank you

I think yur best solution for this is to use a PC. If space is a
consideration you might use a Palm Pilot.

I am assuming you want to be able to identify the person in the photo. A
photo of any quality is going to take several thousands of bytes, ideally
several hundreds of thousands of bytes. You aren't going to be able to
store one picture of any quality in the EEPROM space of an AVR.

If you just want to use the AVR for control and not for storage, you'd
have to decide on what camera to get and then ideally get the service
manual for that camera. I don't have any particular recommendations for
a camera right now. Do some study at the various photo store websites and
look for something that says it has an external trigger feature.

It would certainly be possible to use the AVR to manage a camera, external
nand flash or EEProm, and a communication interface.

There's a small camera on the sparkfun site that they have worked out the
interface on, and you could use something like serial, or bluetooth for
wireless communication through the AVR's serial port.

Communicating at 115200, a picture of reasonable quality will take a few
seconds to transmit.

You can make use of a CMOS Camera Module with compressed output + AVR Mega series + Storage Medium
