STM32F407vgt problem using DCMI

[aamzil.ilyas9]

Posted on March 08, 2016 at 16:02Dear All,I am using an stm32F4discovery ( stm324f07vgt)  to capture images coming from a camera OV5642, i would like to use DCMI but when i create a new project in STM32CubeMX to generate DCMI code, i note that there is a red ''X'' next to DCMI.Any suggestions or advice to help me in this respect ? Best regards

Hello zudse.zeta,

The DCMI pins are disabled because they are already defined and used by other external components of the board.To have more idea about these components, you can refer to the

 User Manual, precisely in the Table 6. STM32 pin description versus board functions.Best Regards-ForumSTM32-

Perhaps you want to review how the

camera was handled, should be code of that in SPL rather than CubeMX, but might provide insight.CubeMX is designed to recognize pin/peripheral combinations that clash, remove the settings/configurations that clash to access the DCMI pins and peripheral.
