Installation #46

Closed sjude68 closed 4 years ago

sjude68 commented 5 years ago

how do I install on Raspberry Pi.

I get error that no suitable version found.

sladaar commented 4 years ago

probably you are trying with python 2.7 Use 3.6 or above instead

I managed to install Python3.7 and then install ledfx on Raspberrypi. Now I get the webpage only on localhost:8888 or 127.0.0.1:8888. I cannot get the webpage on the IP address of the Raspberrypi. Also the ledfx does not work with wled. I get error on the console

about accessing the visualizer remotely i'm still trying to do it myself, so i can't help!

about the ledfx issue i don't know much about the pi, to be honest. It seems some installation/library problem tho. Like, are you using a mic or the mixed audio? It looks like there's no audio input configured. I would try with python3.6 also, but first check the audio input.

sjude68 commented 4 years ago

I am using a USB Mic on the RaspberryPi.

On a Windows 10 laptop Ledfx works fine within Anaconda.

SDLyle commented 4 years ago

I had the same issue. I believe its trying to use the on board sound vs your USB. I found the solution in closed issue #31 The only other problem was trying to figure out which device was which. For that I installed a littte python script with the following : pi@raspberrypi:~ $sudo python3.7 -m pip install sounddevice

followed by

pi@raspberrypi:~ $ python3.7 -m sounddevice

which returned

0 bcm2835 ALSA: IEC958/HDMI (hw:0,1), ALSA (0 in, 8 out) 1 bcm2835 ALSA: IEC958/HDMI1 (hw:0,2), ALSA (0 in, 8 out) 2 2 Channel USB Audio: - (hw:1,0), ALSA (2 in, 2 out) 3 dmix, ALSA (0 in, 2 out)

so in my instance I added the following to my /home/pi/.ledfx/config.yaml file

audio: device_index: 2

I just pasted it at the top and it worked!

ahodges9 commented 4 years ago

@sjude68, the latest LedFx should now auto-detect your IP settings. Just delete the "host" line from your config and restart. We are also working on adding a setting page for the audio settings. For now, you will need to add it manually. Let me know if you have other issues. Closing this out

sjude68 commented 4 years ago

Thanks for the update. It works with USB Mic connected to Raspberry Pi.

Would it work with a pi zero with a SPH0645LM4H mic?
