I am currently working on integrating the SEN0526 I2S MEMS Microphone with a Raspberry Pi and have encountered some challenges. I have managed to record audio using the following configuration, but I am uncertain if it is the optimal setup or if there might be a better approach.


Here is the configuration I added to /boot/config.txt:






After rebooting, I used arecord -l to list the capture hardware devices and received the following output:


**** List of CAPTURE Hardware Devices **** card 2: sndrpigooglevoi [snd_rpi_googlevoicehat_soundcar], device 0: Google voiceHAT SoundCard HiFi voicehat-hifi-0 [Google voiceHAT SoundCard HiFi voicehat-hifi-0]  Subdevices: 1/1  Subdevice #0: subdevice #0


With this setup, I am able to record audio, but I am concerned about the correctness of this method since it involves using a dtoverlay intended for a different device (Google Voice HAT). I would like to know if there is a recommended dtoverlay for the SEN0526, or if there are any additional steps I should take to ensure proper functionality.


Any guidance or recommendations would be greatly appreciated.

It should be possible but you may need to make your own library.
