Hello All,


I am first time working on DCMI with STM32f4 series micro controller.


We are planing to interface DCMI camera with STM32f407 Micro controller.

Camera Resolution is "2592x1944" and Image size goes up to 512kb ~ 2MB.

Camera module consist of ov5642 CMOS.

We have already interfaced Memory card for storage of data.


Is there any external memory(Buffer) is required while camera image capturing is in process?


Is there any possibility to store image directly in to Memory card over SPI interface?
