I have a rasberry pi 3 wearing a Respeaker 4 Mic array that seems to be working alright, but I found one oddity.
After playing with the demos in the 4mics_hat repo for a bit I noticed when the LED's first receive data a single (or sometimes multiple) led will flash white real quick.
Has anyone else noticed this or could I have a faulty unit?
I tried creating a wakeup function to test in the pixels_demos.py script that looks something like:
def wakeup(self, direction=0):
pixels = [0, 0, 0, 0] * self.pixels_number
