      Hi Cor, Yes, I've read. My question is how do you wire the SPU0410 to Teensy? I am using SPH0641LU4H-1 incorporated in a PDM interface (https://www.elecrow.com/digital-mems-microphone.html). How can I wire this...

      Just one more question, sorry, you use a MEMS (SPU0410LR5H) with I2S, right?

      Ok, thank you

      Ok, I will definitely buy the shield, I already read a lot of foruns here and almost all of them use it. With the shield, is it possible to do it easily?

      Ok, maybe it was a wrong assumption. If I buy one MEMS (SPU0410LR5H), can I use it with Teensy 4.1 with a sample rate of 192000 kHz without using any shield or extra board?

      Humm, MEMS (SPU0410LR5H) microphone is an analog microphone, right? I am afraid to use an analog due to the higher noise associated.

      Hello, I am trying to change the sample rate on the teensy 4.1 so I can fully take advantage of the PDM Microphone I am using (https://www.elecrow.com/digital-mems-microphone.html). The microphone can operate in ultrasonic mode, so it is capable...

      The frequency generated by BCLK with "setI2SFreq(192000)" is around 12.30 Mhz. I read it with an oscilloscope. I think this is a problem, as the microphone operates in ultrasonic mode with 3.072 MHz ≤ fCLOCK ≤ 4.8 MHz. Am I wrong?
    • S
      Yes, I have an oscilloscope. I will measure when I set the rate to 192000 hz.

      Isn't "setI2SFreq(192000)" changing the sample rate? I am using this library https://github.com/alfa95139/pt8211-with-Teensy-4.1/blob/main/setI2SFreq.cpp.

      Sorry, it will not happen again

      Hello, I think I have a similar question. I am using Digital MEMS Mic SPH0641LU4H-1 (https://www.elecrow.com/digital-mems-microphone.html) to apply PdM in bearings. I am using Arduino Framework and, according to the datasheet of the microphone...
