Hello,I am working on application that would use microphone array. Together with STM32H735IG board I decided to use STEVAL-MIC001V1 microphone array connected via DFSDM interface. I based my project on example available in CubeMX - DFSDM_AudioRecord ...

Hello,after some work with this application and some support from ST employees I managed to get some pretty good outcome, as you can se on Picture 1. On output I can see sinusoidal wave that I am giving on input of microphones, but I get a lot of off...

Hello Eleon,I checked signal on PE5 pin (SB40 on your board schematic) - clock is clocking with 133kHz frequency, on pin PE4 (SB39) there is always 0 V.Pawel

Hi Eleon,thanks for checking! I did the changes as you suggest:[...] GPIO_InitStruct.Pin = GPIO_PIN_5; GPIO_InitStruct.Mode = GPIO_MODE_AF_PP; GPIO_InitStruct.Pull = GPIO_NOPULL; GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_LOW; GPIO_I...
