FreeRTOS XIAO nRF52840 PDM Microphone Examples

[cam]

Hey everyone,

Currently I’m exploring the microphone on the XIAO sense, but I’m unable to get the example sketches to work on the non-mbed board versions.

Does anyone have any example sketches they could provide?

Thanks!

This is what I have tried, but encountered the same issue as the user in the post below. The difference is that I’m not able to use the mbed board definition for my application.

Xiao nRF52840 and PDM microphone

I will try again with the nRF52840 Mbed version release 2.9.2. I faced issues with the latest non-Mbed version 1.1.3. The recommended solution as per XIAO BLE wont compile ArduinoBLE- Arduino IDE - #11 by msfujino is to use the previous 1.1.1. I fully agree with you. The Xiao boards are incredible pieces of hardware: let’s hope software and collaterals be on par!

That’s fantastic! Do you happen to have the link to the library src as well? Thanks!
