Hello

How can we interface the PCM4202 with a SD card (fat 32) to record wav file on a SD card ?

Any circuits ?

Thank

Hi Eugenio,

We don't have a reference design available for this and the majority of this project is likely configuring the host processor and SD card reader/writer, but you'll need a processor with an Audio Serial Interface (ASI) bus that supports the I2S, LJ, RJ style audio formats to read from the PCM4202, and then you'll need to use the processor to convert this to the proper format and load to the SD card.

Hi Eugenio,

This is a little out of my realm of expertise, but in addition to the TI processor families, we often find our customers working with Raspberry Pi development systems and Ambarella processors with our Audio CODECs. STM has some good options as well.

Hi Collin
ok I'm looking for the most useful processor for this project.
I know the Raspberry / Arduino family very well, they are not useful for this realization.
I will keep you informed ..
thank you very much
