Hi support person,

I purchased an Evaluation ADAU1772 board for my project.

All I would like to do is convert I2S to PDM output.

ADAU1772 is I2S master in this configuration. Please refer to the attachments for the settings in SigmaStudio App


1.The BCLK from ADAU1772 is alway 48Khz regardless wnat I select in "Serial Port FS" section

2. The PDM Output is always there even when disconnecting the I2S source

I'm not sure what I might have missed. Your prompt response is greatly appreciated.

Best regards,

Bob Ngo
