STM3220G_EVAL with OV2640 camera

I have the STM3220G-EVAL board with the 2MP ov2640. Is there example code for this camera like the one in STM32F2xx_StdPeriph_Examples/DCMI/OV9655.

I cannot find much resources available for the ov2640 module. And cannot blindly set up the registers.

Any help would be appreciated.

OmniVision have an application note,

(pdf)

Does that help? Or you can give them your details and request a Data Sheet.

Thanks for your reply John. But that doesn't help to much. I am really after the datasheet, so I can work out what to set all the registers too. Which there is approx 150 of. With no datasheet or example it is quite frustrating.

We've used both Omnivision and Aptina image sensors in different designs. Both companies operate similarly. You can buy a number of their chips from digikey and other distributors. However, to get the detailed programming information, you need to contact the company and sign an NDA with them. Then they'll send you the documentation, often with your company name watermarked in the PDF.

Hi,

There is an example under

standard peripherals library

:

“STM32F4 DSP and standard peripherals library, including 82 examples for 26 different peripherals and template project for 5 different�?.

do you make 12 bits camera sensor work?

I am having problem make STM32F207 DMCI and DMA work for MT9P301 image sensor.

Hi Scott,

There is an example code for OV2640 camera under STM32F4xx standard peripherals library

STM32F4xx_StdPeriph_Examples/DCMI/Camera.

http://www.st.com/internet/mcu/product/252149.jsp

This example supports OV9650 and OV2640 cameras.

Hi Guys

I've tried the example from the F4 eval board and am getting an error on the IO expander initialisation code. Specifically ioe_config() fails. Appreciate any ideas as to why.
