LAUNCHXL-CC1352P: How to change the I2S role of LAUNCHXL-CC1352P and CC3200 AUDIO Boost

For the audio plugin the Launchpad is master and the AUDIO boosterpack is slave. Please see how the code is written and how I2S samples are requested/ pushed.

Why do you want to set the Launchpad as slave? And not clear, do you want to set the boosterpack as master? 

Hi Marie,

Thanks for your reply!

The I2C and I2S are OK. Because It can transfer the audio from line in to line out if run the example code of  the audio echo.

Thanks.

Hi Ter,

Yes, I just want to debug and verify some issue of the I2S IF.

Thanks.

To change the master/ slave configuration you have to rewrite the full code and it sounds like it should exist easier methods to do what you want to.

What type of issue are you trying to debug? 

I have tried to modify the I2S.c, But It coud not be compiled.

The issue is the audio noise.

hi  TER:

      The problem is described in this url ""

Hi all,

There is no need to fully rewrite the code when changing the I2S driver from Slave to Master mode. This is handled by the audio plugin already. 

The issue here seems to be due to a problem in the hardware configuration. Please review the section Hardware Setup of the SimpleLink Audio Plugin Quick Start Guide. One sub-section is dedicated to setup the CC3200AUDBOOST properly for I2S slave operations.

I hope this will help,

Kind regards,

Hi Clément,

Thanks for your reply!

For the hardware config, I would try to modify it.

And How to config the software for the I2S role?

Thanks.
