Respeaker mic array v2.0 DOA #45

Open maulikmadhavi opened 5 years ago

maulikmadhavi commented 5 years ago

I am using respeaker microphone array v2.0 for DOA application in ubuntu. I was following the reference from http://wiki.seeedstudio.com/ReSpeaker_Mic_Array_v2.0/

1) during Update Firmware, while running dfu.py I got ValueError.

sudo python dfu.py --download 6_channels_firmware.bin # The 6 channels version

Traceback (most recent call last): File "dfu.py", line 229, in main() File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 722, in call return self.main(args, kwargs) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 697, in main rv = self.invoke(ctx) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 895, in invoke return ctx.invoke(self.callback, ctx.params) File "/usr/local/lib/python2.7/dist-packages/click/core.py", line 535, in invoke return callback(args, **kwargs) File "dfu.py", line 218, in main dev = XMOS_DFU() File "dfu.py", line 198, in init super(XMOS_DFU, self).init() File "dfu.py", line 73, in init raise ValueError('No DFU device found') ValueError: No DFU device found

2) Furthermore, while running doa.py, I got nothing. Also running separately following on python, dev variable is empty.

from tuning import Tuning import usb.core import usb.util import time

dev = usb.core.find(idVendor=0x2886, idProduct=0x0018)

Please help me, thanks in advance.

Do your computer recognize the usb sound card? You can use lsusb to check.

The usb mic array may already contains 6 channels firmware. You can use audacity to check how many channels does the sound card has.

By running lsusb, I got:
