How to configure i2s example to get the data from four PDM mic through ADAU7118Z PDM to PCM converter
Posted: Tue Aug 22, 2023 11:17 am
Hi Everyone,
I want to get data from four PDM mics which are connected to EVAL-ADAU7118 (PDM to I2S converter). My hardware setup is as per the below diagram. I am able to get data from two mics PDM1 and PDM2 but I am not able to get data from the PDM3 and PDM4. I think I have to configure my Arduino firmware application of i2s to get data from four channel. Is this a correct understanding? If yes, what is the configuration I have to do in my application to get data from all four mics (channel)? Kindly guide.
Thanks,
