Hello, I want to read data by STM32H745BI from external ADC AD9235 with parallel interface. I suppose to connect by FMC. Tell me please how to connect correctly and choose right FMC Mode and Configuration in STM32CubeMX. Thanks!

Hello @vagar.1,

FMC is not suitable for interfacing directly with an ADC like the AD9235. You may need to check the datasheet for more details.

Hello again @vagar.1,

You may need to refer to the external ADC documentations to get more information. If the protocol requirements for the FMC parallel interface are supported for this peripheral, maybe it should work.

Have you tried to test it?

@vagar.1, You may need to check the ADC configuration and check waveform, flags... for data reading format.
