How to configurate AIC3106 on omapl138 LCDK?

Other Parts Discussed in Thread: OMAPL138, SYSBIOS

Hi,

I'd like to configurate AIC3106. But I can't understand how can I write registers by I2C?

I thought that there is some function in linux driver, but as I understand at this doc
http://processors.wiki.ti.com/index.php/Omapl137_linux_audio_driver
There are only aplay and arecord.

Thanks.

Hi Alexander,

We have starter ware test playback code for AIC31 at "OMAPL138_StarterWare_1_10_03_03/examples/lcdkOMAPL138/mcasp/mcaspPlayBk.c"

There are only aplay and arecord.

Q) Are you working with linux or SYSBIOS (TI-RTOS) or no-Os like starter ware?

Sorry for my fault,

I'm working with linux from mcsdk.

Command aplay is working well. I just want to understand how can I configurate AIC.

Thanks!
