Hi Johnson,

You can use TDM and I2S simultaneously using different SPORTs, one is configured for I2S and other is for TDM. I have attached separate example code for both.

Hope this helps.

Dear Jithul,

In our project, we need use sigmastudio schematic ( adi_ss_schematic_process( ) ) for reverb,mixer, EQ and so on functions

In offical ADSP-21489 EZ-Board Support Package

( BSP,CCES\Default_Application_for_SS4SH\examples\SigmaStudioForSHARC.sharc_2.2.0\Demo-app\Demo) release, only

suport TMD or I2S at one time, we'd like to suport TMD and I2S at the same time,( in other projects, maybe need support

different TDM, for example, TDM512 and TMD256 (or TDM128) at the same time)

Would you please support some documets and reference source code about them.

Best Regard
