I use an AD1835 with the ADSP21369 EZ Kit Lite and I want to work on mono signal. Is that possible to configure the AD1835 to just "send" to the DSP one signal and no the "right-left-right-left..." serie ?
Thanks for your answer.

I think it should be possible. The AD1835 can be used in DSP mode for this purpose. In this mode it does not differentiatle left/right channel. You can configure the ADSP-21369 SPORTs also in DSP serial mode to receive and send data from/to CODEC.
I configure the AD1835 in "DSP mode" and I keep the ADSP 21369 in OPMODE but I still have one sample which represent my signal ans one sample at zero. Even if the DSP mode does not make the difference between right and left, is it possible that the codec continue to acquire one sample one each in ?
Althought the amplitude of my acquired samples is four time more important that my signal's one. Is there a amplification in the DSP mode ?
Thanks for your answers.
