hello
I have a module with digital audio interface and I have never used digital audio, so you know this and embrace it as I see it as a linux device. The module consists of the following pins:
REF_CLK output Clock
NC (FS_OUT) input (Output) RX
REF_CLK output TX
BITCLK Input Reset
FS_IN Input
RXDAI Input
TXDAI Output
Anybody could help me?. Thank you very much.
Greetings

Are you looking for hardware advice? or software advice?

Hello Robin
Thank you very much for responding ;-). In both, if you know Blackfin is capable of supporting this interface and uClinux is able to detect it as a device (example: / dev / dsp). Thank you very much.

The answers depend on exactly what the device is - for hardware support - the best place to go is :
forms.analog.com/Form_Pages/support/dsp/dspSupport.asp
Make sure you select " processor issue".
As for software - it depends on how the part is configured. (SPI, I2C or over the Data pins)?
