Hi, Invensense Team.
Greetings from LTTS user.
We stated working on the ICS-41351 sensor, also we are referring ICS-41351-v1.3 datasheet.
We need some more information about the sensor functionality, Interface and validating the sensor.
Need More Info :
1. Need some reference code to reuse and refer our application purpose ?
2. How to validate the sensor ( Any mappings are available to validate the sensor with respect to input) ?
3. This sensor output is PDM format how to decode ( any codec available ) ?
1st level Activity we have :
1. Interface validation
2. Sensor Validation ( Boundary Limits )
3. Functionality Validation
Note : Currently we are using MCU as CC2652RB Launchpad and ICS-41351 sensor.
Please help us to achieve this activity's by providing the valuable information.
Please see my comments on another inquiry at the below link.

HI @jin jiang
Reading my previous question, I got some clarity.
But I have few question to be clarify still in the audio perspective
1. How to validate the PCM Samples(Input Vs output )?
Note : I have converted PCM samples from PDM mic using software codec. That input which I given to the mic is generated tone of 1kHz using Adacity.
2. Is there any way to convert that raw PCM samples to volume level like dB ?
Please share your valuable points and suggestions.
