Using XIAO ESP32S3 Sense camera and mic simultaneously

Products & Technology
1

The code examples for cam and mic both use I2S0.
I2S1 does not support PDM.
Is there a workaround for this to allow camera and mic to operate simultaneously?

Is there a reason an I2S mic was not supplied. It needs one more pin, but the D2/SD-CS pin is not needed if the SD card uses the MMC library.

Found out that although camara lib for ESP32 uses I2S0 DMA, the ESP32S3 uses GDMA, so PDM mic can be used simultaneously

Hi sorry. I’m brand new to the Seeed line of products. Where is this documentation for accessing the mic and camera on the Sense devices? I asked tech support but they only pointed me to the Sense wiki, which only has the Blink sketch. All I can think is there is a language barrier. Thank you!

I also need some sample to make them work simultaneously, does anyone have a clue on how to do it? Thanks!
