Hi Team,

Is it possible to connect TDM microphone directly into PCM interface of DA1469x?

In the DA1469x datasheet it is mentioned as follows.

Audio blocks: This part enables audio streaming by means of a Pulse Density Modulation (PDM), a Sample Rate Converter (SRC) and a Pulse Code Modulation (PCM) interface. It can support up to 2 digital microphones or 2 digital loudspeakers using the PDM interface or connect an external CoDec at the PCM/I2S interface.

Only ext. CoDec can be connected at the PCM/I2S interface. Please clarify. I am new to this audio world :-)

Hi Dialog,
I wana connect an I2S microphone to DA14681 microcontroller and get data of that.
Is there any sample or reference code for implementation and initialization of I2S peripheral in DA1468x?
if is not, what can i do?
