Microphone data from X-NUCLEO-IKS02A1 on nRF5340 DK

#1

Hi!
I am trying to acquire microphone data from MEMS microphone located on the X-NUCLEO-IKS02A1 shield plugged in the nRF5340 DK. Can you please guide me what I have to modify in the Edge Impulse firmware for nRF52840 DK for the microphone data acquisition?

Thanks for your reply!

Hi @svenkada,

You would need to rewrite this driver file to work with a different microphone: https://github.com/edgeimpulse/firmware-nordic-nrf52840dk-nrf5340dk/blob/378a18e73ea564f0316cda2493860b4158050d4f/edge-impulse/ingestion-sdk-platform/NordicSemi-nrf52/sensors/ei_microphone.cpp
