how to configure amplifier with xmos

Postby twittich » Tue Dec 03, 2019 10:32 am

Hello
i'm working with windows and linux using the dev kit:
"VocalFusion 4-mic mono-AEC circular dev kit" and "xtag3" programmer. I'm using the "vfk_spk_base" and the build "1i2o2_circ43_48khz" .
The dev kit uses the Cirrus Logic CS43L21 and now i will use the TLV320DAC3120 which is connected via i2s and i2c with the xmos.
How and/or where can i send configuration through i2c in the project "vfk_spk_base" to setup the amplifier?

Thanks in advance

Some more questions regarding the amplifier configuration.
The mentioned build ("vfk_spk_base" and the build "1i2o2_circ43_48khz") what is the codec interface word length and the lrclk and bclk and where can it be set ?

Thank you in advance.
