How to read input level for ADAU1452?

Hello Fish,

I have attached a test program. The details are in the file as comments.

I do want to mention that if you are going to use a sample rate higher than 48kHz then I recommend that the serial output port be setup as a master and the serial input ports be setup as a slave. You might have to increase the drive strength of the clock and data output pins. This all depends on the PCB layout details.

Hello Dave,

Thanks for you reply.

My points is reading level by MCU.
From your example project, I export to file and got a one file, "ADAU1452 TDM8 input and output test_IC_1_PARAM.h", the contents for level 1 is,

How can I use these address to read data by MCU, please suggest.

Thanks.

Hello Fish,

Have a look at this post:

https://ez.analog.com/dsp/sigmadsp/f/q-a/118203/reading-meters-with-a-controller-on-the-adau1452

This should get you started on how to read the meters with a microcontroller.

There are other posts that will help with this question.
