Part Number: PCM2704C

Hi,

I would like to have the PCM2704C recognized as a speaker on an Android tablet. Is it possible to do this by writing it in EEPROM?


Best regards,

Hi Koshiyama-san,

Yes an EEPROM can be used as external ROM to change the device descriptors. See the steps in Section 9.3.7 of the datasheet.

Dear Jeff-san,
Hello. Thank you for your reply.

What value should I change in the 57 bytes in order for the Android OS to recognize speaker mode?

Best regards,
Kazuaki.

Hi Koshiyama-san,

Unfortunately we are not experts on Android OS and what the correct bytes would be. You would need to look in the documentation/support of Android OS. However once you have the bytes you need and have issues programming, then you can come back to TI for assistance.

Thank you,
Jeff McPherson
