no pixel_ring control with xvsm_0x32_20170329.bin or both Raw firmwares ??

[elpimous]

hi all,
on xvsm_0x032_20170324.bin firmware, I can control pixel_ring via python lib.
I changed firmware to improve specs, but now, I can't control pixel_ring functions anymore !
Is there any reason ?
Could we hope a last firmware revision, with pixel_ring control ?
Thanks Respeaker team

The default firmware with DSP works with the pixel_ring.py of this repo

The raw 8-channels firmware works with https://github.com/respeaker/mic_array/blob/master/pixel_ring.py

Which one did you use?

hello, xiongyihui.
First, I wish you all an happy new year...(health, success...)

Now, firmwared again my respeaker 7 mic array microphone with :
sudo ./dfu --download ReSpeaker_Mic_Array_firmware_xvsm_0x32_20170329.bin
Success.
Next :

Python 2.7.12 (default, Nov 20 2017, 18:23:56) 
[GCC 5.4.0 20160609] on linux2
Type "help", "copyright", "credits" or "license" for more information.

>>> import respeaker.pixel_ring as pr
>>> pr.wait()
>>> pr.off()

Well, I tested all pixel_ring functions, and the respeaker mic array stays in "listen" mode (green direction light)

Strange ?!

An idea ? (this is the same mic array that produces an electronic noise on records)

That's weird!
Cloud you try the raw audio firmware to verify the leds and the microphones for the electronic noise?
After changing to the raw audio firmware, you can use https://github.com/respeaker/mic_array/blob/master/pixel_ring.py or https://github.com/respeaker/pixel_ring to control the leds, and use audacity to verify recording.
