I want to get mic data to localize where the sound source is and move the RC car to the source.
In demos, there is mic_demo which gets 8 mic data to array. But the frequency is so fast that RC car can’t
use it. So I decrease sampling frequency changing to
but the code didn’t work. I think the code is integrating the power, so when the frequency goes down, integration range is larger and the code always print out 8 or 9.
How to get mic data slowly? How to speed down the code?
