Hello. Is it possible to replace microcontroller with stm32f407? Reference manual and data sheet goes jointly for both microcontrollers. Does anyone have experience of replasing chip? I need dcmi interface to work with cmos camera that exist only on 407 chip.

DCMI used pins:
1) HSYNC - PA4 - FREE
2) VSYNC - PB7 - FREE
3) PIXCLK - PA6 - FREE
4) D2 - PC8 - FREE
5) D4 - PC11 - FREE
6) D6 - PB8 - FREE
7) D8 - PC10 - FREE
8) D9 - PC12 - FREE
9) D10 - PB5 - FREE
10) D0 - PC6 - used by nrf
11) D1 - PC7 - used by nrf
12) D3 - PC9 - used by I2C
13) D7 - PB9 - used by motor 4
4 pins busy - a bit out of luck. If not use NRF - there is 2 pins.
Are there any ideas?

Are you sure the stm32f407 contains the camera interface in the 64 pin package? Just checked and its only available in 100 pin package.
We run a master thesis a while back trying to add a camera to the CF1 and use the nRF link to transfer images. Please have a look at
this blog post.
Please share what you want to accomplish and we might be able to help you out.
