Fermion i2s mems microphone with raspberrypi
i want to know how to use this microphone with raspberry pi 4 4GB model.
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.Tedfsan
It should be possible but you may need to make your own library.bidrohini.bidrohini
