I drive ov2640 camera with stm32f407 by DCMI and DMA. I can get image with 160*120 resolution, so I shoud use uint16_t buff for this resolution.
The problem is if I want to use higher resolution for example 640*480 my stm32 should have 307200*2 byte for storing the image receiving from dma to the buffer. but there is no such space in stm32f407. could you please guide me? is there any way to get the image data in a smaller part!?
