TLV320AIC3254EVM-K: TLV320AIC3254EVM-K and Purepath VAD + AGC configuration

Hi Bruno, 

I have looped in our algorithm expert, but I know you can connect this to a GPIO output component that could be used as an interrupt,  but our expert would be more familiar with any internal routing that is possible.

HI Steve, good to know, i was expecting that this could be handle internally by the TLV, lets  wait for your expert feedback.

Thanks for your help

Hi, 

another question is regarding the I2S output, the framesync got a frequency of 44kHz, is there a way to reduce it?I've checked the ''clocks/interface'' tab on thre AIC3254 CSapplication but no modification on the signal.

my module to be connected to the TLV got a configuratble frame sync of 8,16 or 32kHz, the alternative is to configure the TLV as slave but I didn't find how to configur the TLV in slave mode, if you can assist.

About the VAD I've tried the following process but i've got a build error, i guess the VAD got an output from -1//1 and the GPIO is not handling it...

Regards

Bruno

Hi Diljith,

Thanks for your reply.

I've changed the board firmware PCM is now running at 16kHz, but how can i switch it into slave mode?

About the GPIO, it is fine, the process is now compiling and running on the EVM board, but the GPIO output still not mooving when I'm speaking, i just got some regular pulses (63us every 2.4ms). If you can suggest what i can check, bellow the configuration of my GPIO block :

Thanks!

Hi Gents,

Sorry to bother you, but If someone can assist about what could be the reason why my GPIO is not working as expected.

regards
