Hello @Yjang.1​ ,

I haven't tested your project since I don't have access to that specific board as I'm working from home, but the DFSDM audiorecord example should work.

Make sure that your are using the right pins and configuration according to the STM32F769 Datasheet and UM2033 User manual Discovery kit with STM32F769NI MCU.

I also advise you to have a look at this section: "DFSDM peripheral configuration tutorial", in the DFSDM application note: AN4990 "Getting started with sigma-delta digital interface on applicable STM32 microcontrollers". Tthis will help you on the DFSDM configuration.

Hope this helps you!

Hmm.. I think i revised correctly. but it doesn't work as well. It's little bit difficult for me porting the example on my board. Compile is Ok. In debugging, stuck in 879 lines.
