OV7620

Can anyone tell me if the camera OV7620 will be compatable with this project? I cannot source the ov6620 anywhere (UK Based) so this seems to be the only available one for me.

Cheers

Hello,
The OV7620 is not compatible with this project. The OV7620 has a 27 MHz crystal source to clock the chip (since the chip delivers a higher resolution of 640 x 480), and this speed is too high to also clock the AVR mega8 synchronously with it. That is, in the current configuration...

If you wanted to add a flip-flop between the OV7620's external clock output line, and the crystal input line of the mega8, you would be clocking the mega8 with a 13.5 MHz signal which would work. You would be operating on a decimated frame though...and this would obviously require hardware changes.

You should be able to purchase the OV6620 from http://www.electronics123.com , which is located in the US but most likely will ship to the UK.

Do you offer shipping of your kits to the UK? If so how much? :?

Slightly off-topic, but yes, I can ship to the UK. Cost is around $20 USD.
