DSP vs. Codec Slew

Question asked by BobWalker on Nov 17, 2010

How does one go about adding a DSP slew algorithm for the ADAU1761? If I turn off the codec slew, the signal disappears.

I have found the DSP Driven Output block for LO_L and LO_R. However, I can find no information on how to use these. Can someone clarify how to set up the audio path from DSP ----> slew_algorithm ----> DAC (w/o slew) or point me to some documentation? I don't need the algorithm, only the means to connect the algorithm between DSP and DAC.

 

Thanks.
