Hi There, generally speaking,

Hi There, generally speaking, you'll need to use a driver on the nrf52840 to interface to set-up the DA7212 via the i2c (for configuraiton) and for data, you'll need a i2s driver to interface and send the audio data to the DA7212 from the nrf52840 (assuming you're streaming audio data from nrf device to the DA7212).

nrf52840 supports i2s according to the web site.
