STM32U575 and DCMI connections(Camera)

[NoaTech]

Hi all,

I'm trying to connect between STM32U575ZITxQ to DCMI connections.
I found every single port in ST to the camera except "DCMI_MCLK"(external clk).
I looked at the DataSheet and Reference manual but I didn't see any information about the camera's connections.

Could you please help me with that? how can I connect that? which pin in ST? 

Thanks,
Noa

Hi @NoaTech 

There is  AN5020 which details through use cases the configuration of the DCMI.Here is the link to download the document:https://www.st.com/resource/en/application_note/an5020-digital-camera-interface-dcmi-on-stm32-mcus-stmicroelectronics.pdf

In addition, there is an example available in the STM32U5 HAL library: https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/STM32U575I-EV/Examples/DCMI/DCMI_ContinousCap_EmbeddedSynchMode

Hello @NoaTech and welcome to the Community ,

As already mentioned by @Diane POMABIA , the AN5020 details the connexions between the camera module and the STM32 MCU in Figure 5.

So, the "DCMI_MCLK"(external clk) should be connected to an external clock pin.

In your case, and after check the STM32U575ZITxQ datasheet, you can connect the "DCMI_MCLK" at pin 24.
