Hello!

From a cursory glance at the datasheet it seems like there are many pin conflicts between DCMI and FMC on the F7. Does that mean they cannot be used at the same time?

Isn't that a bit of an oversight, considering image data often take quite a bit of memory?

Thanks

Matthew

    Perhaps, it depends on how many pins your chosen device has, and the may be overlap or alternate options. Historically some of the AF muxing choices had been a bit brain damaged. (SDIO or ETHERNET vs LCD on the STM32F429I-DISCO)

    Haven't done the due diligence on the pins here, does CubeMX provide escape on the maximal pin product?

    Ahh yes of course. Had a brain fart, thanks!

    Forgot they can be on multiple pins!
