PCM to I2S format conversion

[jamesdeepu]

I have two bluetooth chips connected to IMX6 via I2s interfaces. BT chip1 currently supports PCM format audio data and BT Chips2 supports audio in I2S format.

How will I convert PCM format audio data from BT chip1 to I2S format for BT Chip2 ?

thanks in advance.

HI Igor,

Can the SSI interface on IMX6 support the following PCM formats below?  What mode should the SSI be in to support either the long  or short frame sync? 

Thanks Gus.

Hi James

PCM is generic abbreviation used for many kinds of formats

Pulse-code modulation - Wikipedia, the free encyclopedia

you can analyze what is used by BT1 from its datasheet and

check if this could be supported by i.MX6 audio modules: SSI or ESAI,

then configure audio driver appropriately. Please check Chapter 25,61

i.MX6DQ Reference Manual (rev.2  7/2014)

Processor can not convert one PCM format to another.

Best regards

igor
