Respeaker 2 MiC hat: Does it support Jetson Nano or is that in the roadmap

Thank you for clarification.

I test the led with the repository https://github.com/respeaker/mic_hat but I couldn’t get the led to turn on. Here is the error that I got.

nano@jetson:~/mic_hat$ python3 pixels.py
Traceback (most recent call last):
  File "pixels.py", line 130, in <module>
    pixels = Pixels()
  File "pixels.py", line 25, in __init__
    self.dev = apa102.APA102(num_led=self.PIXELS_N)
  File "/home/nano/mic_hat/apa102.py", line 93, in __init__
    self.spi.open(bus, device)  # Open SPI port 0, slave device (CS) 1
FileNotFoundError: [Errno 2] No such file or directory

Seems like it’s not able to open SPI port ? In raspberry you have to open the port using raspi-config, I tried with /opt/nvidia/jetson-io/config-by-hardware.py in the jetson nano but I didn’t change anything.

The second test about recording and playing echo didn’t work:

  • I connected a JST speaker to the respeaker hat but I don’t have any output out of it.
  • I tried to record something with the mics of the respeaker but that didn’t work
  • However, when I connect an external speaker to the jack port and it works.

Do you think that alsa configuration is missing ? I remember having a lot of problems with the file /etc/asound.conf in the raspberry.

Thanks again for you answer @turmary
