Issues with Respeaker 4 LEDs

Hi,
I am Spandan from Indian Institute of Technology, Bhubaneswar. I am doing
acoustic source localization experiment with the ReSpeaker 4. I would like
to know about how to blink the ReSpeaker hat LEDs according to my direction
of arrival.

Thank you.

Hi there,


If you use the respeaker 4 mic pi hat for raspberry pi, you can refer to https://github.com/respeaker/4mics_hat/blob/master/kws_doa.py

position = doa.get_direction()
pixels.wakeup(position)

Here is the library for pixel-ring. https://github.com/respeaker/pixel_ring/


Thanks
