Is there any example of using audio codec over I2S on STM32WB? I have the stm32wb5mm_dk BV_FULLBAND example and the audio SAI1 is initialized for external microphone mems. But i want to record 48kHz stereo audio instead and i am looking for an example.

Hello,

In the FP-AUD-BVLINKWB1 – FullBand example, the microphone it’s not used, so you can use the SAI to connect an external audio codec (you can see an example available for other STM32 family here: https://www.st.com/en/embedded-software/x-cube-soundter1.html).

Anyway if you just need to record the received stereo music @48kHz, you can use the FullBand FW as is, connect the board to the PC via USB and record the audio for example using Audacity, you can find more information in the User Manuel of the FP-AUD-BVLINKWB1.

Best Regards
