Question asked by Dimitri Becker on Nov 11, 2015

Hi all

 

I want to use the FRDM-KL46 Board as usb to I2S converter.

 

I've started with the audio generator example code and tried to change the descriptor.c to be both, speaker and mic

(see the code attached), no succes :-(

 

I'm on KDS 3.0  with ksdk 1.3

 

 

Best Regards
