Hi,
task is to develop a software test suit for ICS-41351, below are some queries regarding ICS-41351.
Queries:
with respective what frequency input, what should be the expected output?
how to decode the PDM data?
Any sample code available for validating the Acoustic sensor?
Please rephrase with your first question about "frequency input" and "expected output". I am not exactly sure what you are asking.
As for how to decode the PDM data, typically what people to is to covert that to PCM data (16 bits with a certain sample rate). DSP factions can be run more easily on PCM audio data.
We not not provide any code for validating acoustic sensor from a system level perspective. That is typically your own requirements and writing a piece of code to verify the audio data.
