Regarding the wiki at ReSpeaker USB Mic Array | Seeed Studio Wiki, none of the python examples work. They all generate this error backtrace:
Traceback (most recent call last):
File “/home/m/usb_4_mic_array/tuning.py”, line 197, in
main()
File “/home/m/usb_4_mic_array/tuning.py”, line 188, in main
print(’{}: {}’.format(name, dev.read(name)))
^^^^^^^^^^^^^^
File “/home/m/usb_4_mic_array/tuning.py”, line 109, in read
response = struct.unpack(b’ii’, response.tostring())
^^^^^^^^^^^^^^^^^
AttributeError: ‘array.array’ object has no attribute ‘tostring’
Also, some of the examples use the print call as in:
print Mic_tuning.direction
I believe this needs to be:
print Mic_tuning.direction()
Any ideas?
