I have this error message when I try to run "respeaker_v2_pixel_ring.py" on my Respeaker Core V2. My mraa libs are updated and all is properly installed..
respeaker@v2:~/pixel_ring/examples$ python respeaker_v2_pixel_ring.py
Traceback (most recent call last):
File "respeaker_v2_pixel_ring.py", line 15, in
en = mraa.Gpio(12)
File "/usr/lib/python2.7/dist-packages/mraa.py", line 755, in init
this = _mraa.new_Gpio(pin, owner, raw)
ValueError: Invalid GPIO pin specified
If someone has an idea to fix this problem it will be great! Thank you
