Regarding imp34dt05 mems sensor configuration

[AmitUpadhyay]

Sir,

I am working on the imp34dt05 sensor but how could we configure its parameter.Could u guide us for that.

What should be sampling frequency and what is the range of the frequency that it can capture and what should be sampling frequency of pcm and what should be size of pcm output and what should be size of buffer and data size of pdm output captured by the stm32f4 controller?

For the I2s peripheral, you can just follow the example from AN5027, yes you will need to use an external timer to provide signals for both mics based on that document. I am not an expert and am still learning but you can also try to use your own clock as an alternative.   Please also check STM32 microphone audio acquisition 8 part YouTube series to understand more about PDM2PCM conversion library.
