B-U585I-IOT02A , how use micro (sound) for detection

[bn_technilab]

Hello the community ! 

 

I would like make sound detection default with the B-U585I-IOT02A

 

I had use the nanoEdgeAI studio, create my project, with microphone (picture 1)

 

I had create the data logger Analog 1 axis (picture 2)

 

And i have this curves, is this normal ? with or without sound i have the same curves. (picture 3)

 

thanks.

Hi,

i have no idea, what you do there….

but your FFT shows: there is no signal (except some DC offset, thats usual.)

So at first check the input, then next stage : is there a signal (= data with strong “noise” ).
