I tried to install this into an existing install of Python 3.7. Since it depends on the existence of portaudio, my choices are between installing the full visual studio toolchain so I can compile portaudio or install the 460 MB anaconda package so IT can compile portaudio.

Why is this a thing?

Changes to mel code leave energy effect not working

File "...\effects\energy.py", line 22, in audio_data_updated lows_idx = int(np.mean(self.pixel_count * data.melbank_lows()) ** self._config['scale']) AttributeError: 'MelbankInputSource' object has no attribute 'melbank_lows'

Is there an easy way to swap RGB order?

I am running the latest Raspbian Buster (as of 2-5-2020) on a raspberry pi 3 with a PS3 Eye camera attached. I am able to select the device in the web ui [Current device: USB Camera-B4.09.24.1: Audio (hw:1,0)] and it populates the config.yaml file with "device: 2". I have also used arecord to verify I can record audio to a wav file correctly. I am getting the following error when trying to select an audio reactive effect in the ledfx ui. I suspect the error has something to do with the PS Eye camera having 4 different audio channels. Has anyone got the PS Eye camera working with ledfx on a raspberry pi or otherwise? I am using Python 3.7.3 which is installed by default on my version of Raspbian.

Wavelength effect is failing with a odd number of pixels. Likely due to how the effect uses zip to combine.

I am running "scottlawsonbc audio-reactive-led-strip" firmware on a NodeMCU esp8266 board and I followed the installation guide. I can get nonreactive effects like "Gradient" to work seamlessly. But whenever I select a reactive effect like "Energy", nothing happens. I'm on a mac, maybe that's the problem? I'm totally new to all of this so sorry for the (maybe) stupid question, but how do I get audio input to work? I'm sure I should provide more info, but I don't know what to provide so just tell me what and I'll provide it.

I am getting this error after this command on anaconda
"OSError: [WinError 193] %1 is not a valid Win32 application"

Running Windows 10 64 bit
Running Anaconda

What to do?

First of all, thanks a lot for this project, it's awesome!

So, i'm on windows and installed ledfx in Anaconda.
To run the visualization i needed a shortcut without entering the environment, so i found the executable in
C:\Users"myuser"\Anaconda3\envs\ledfx\Scripts\ledfx.exe
and so far no problems.
BUT, when i close the window it seems i lose the configuration file,
C:\Users"myuser"\AppData\Roaming.ledfx\config.yaml
or however i can't run the visualization no more because it fires me an error:

Loading` configuration file from C:\Users\mbibox\AppData\Roaming\.ledfx

During handling of the above exception, another exception occurred:

    raise er.MultipleInvalid([e])

Thanks in advance!

with further investigations it seems that executing that exe could be the problem, because running the script inside the anaconda environment could resolve the issue.
So i'm trying to create a shortcut to activate the env AND execute "ledfx" command.

I've been playing around with it for awhile but can't seem to get LedFx to find any audio devices on the Pi 3b, when I think it should be able to find the onboard device.

I was looking to have the Pi be used as a bluetooth or spotify device and play sound through the audio jack to speakers. The sound works coming out of the jack, but can't seem to get it to work with LedFx.

I also tried manually adding the device in the config file but this would crash LedFx (Seg Fault).

Not sure if this is a problem with a dependency or not.

Within Manage Devices, can edit the LED1, to assign reactive audio settings for channels from one of the following options:

• mono
• stereo
• left
• right

Install completed successfully (?), but upon running program gives error "failed to create process." with no further info.

Is it possible to activate a preset via the API so I can control LedFx via HomeAssitant

I found a integration for Home Assistant but it seems like its a full version of LedFx (which is awesome just not what I was hoping for) as opposed to a integration more geared up towards control

Also as a bonus is it possible to stop control via the api?

btw sorry if I'm being thick and the solutions fairly obvious

Just wanted to start up a thread for general discussions about the project. My main focus currently is building up the core backed to be extensible such that adding new devices and effects is easy. My second focus will be on updating the front end to support the full REAT API (essentially user friendly version of the developer tools page) which I am looking into using React.js

Is there any core functionality that people think is missing? Open to any architectural changes as well (better sooner rather than later!)

Please create new issues (tagged with enhancement) for any feature request

I also created a discord channel to make discussions easier if necessary: https://discord.gg/wJ755dY

Could anyone help me? Thanks in advance.

Good day,
Can I somehow connect this project with Home Assistant?
Do i need to configure rest api connect in homeassistant, relying on your documentation?
Thank you!

1. Editable Device

Environment: Device Management
Ability to edit the device.

2. Basic Device Effect Saving (bug)

Fixed and Deployed
https://github.com/simon-wh/LedFx/commits?author=simon-wh
Tested and is working. Thanks @simon-wh 👍
Got this bug though: https://github.com/Mattallmighty/LedFx/issues/2

3. Dashboard

Environment: Dashboard
Deployed
Added display current effect - pulled from the API, and can have an overview of what is being pushed to devices.

4. Audio Channels

Environment: Device
Within effect, can select to assign reactive audio settings for channels from one of the following options:

• mono
• stereo
• left
• right
  Would also be good to have Material UI: Range sliders for the audio frequency you will use on the effect.
  Front end done, but backend audio.py needs to be actioned;
  

5. Click on device name loads current effect of the device

Environment: Device
Fixed and Deployed
When you click on the device name, will do an API call: http://127.0.0.1:8888/api/devices/102/effects, loads front end material-ui inputs with the current set effects.
For example:
Click on device 102
Does API call: http://127.0.0.1:8888/api/devices/102/effects
API call is: {"effect": {"config": {"brightness": 1.0, "blur": 4.0, "scale": 1.0, "Audio_Channel": "Mono", "mirror": true, "flip": false}, "name": "Energy", "type": "energy(Reactive)"}}
And will put the front end options in place from the API call

6. Front End change Material UI: Slider in device effect

Environment: Device
Add in Material UI: Slider to replace brightness and other device effect settings.
https://material-ui.com/components/slider/ - Tooltip value label

7. Group Devices

Environment: Device Management
Within Manage Devices, ability to group devices, so can set effect and deploys to two devices at the same time.
Example: Manage Devices, can edit: LED1 to link with LED2. When LED1 is updated, so is LED2. LED2 will be greyed out/cannot select device option.

8. New effect: WLED

Environment: Device
Rethinking this, I don't this is possible via the WLED API due to the delay in E1.31 mode to WLED effect mode.
Within Device, effect option will be: WLED.
Need to get from API 'ip_address' feild to use as a string, for example: http://127.0.0.1:8888/api/devices/102
As soon as selected WLED from dropdown (Async), disables E1.31 multicast of the device, and will then have full flexibility to select Effects, Palettes, Effect Intensity - as the option is selected.
Like what Frenck has done on Home Assistant: https://github.com/frenck/python-wled
https://cdn.discordapp.com/attachments/621678796101124106/641272718574223372/68167769-f42f5300-ff66-11e9-896c-3c29c8da3252.gif

Backend: https://github.com/Aircoookie/WLED/wiki/HTTP-request-API

9.0 Save Presets

Environment(New): Presets
Deployed
Create "Presets" of all LEDs devices current effect settings.
Under Device Management, bottom right hand corner have a button that, pops out that allows the user to create a name of the preset(For example: Default), upon clicking save, saves all the current effect settings pulled from: http://127.0.0.1:8888/api/devices and save to config.yaml.
C:\Users\mattallmighty\AppData\Roaming.ledfx\config.yaml
When you click on preset, it will POST in place all the current effects for all the devices.

9.1 Keyboard & MIDI input trigger

Environment(New): Presents
Rethinking this, we can achieve this in Q light plus - Fuctions: Script - LedFx API Activate preset and assign MIDI button on launchpad to deploy effect.

Keeping the below as backup...
Assign a keyboard key, or MIDI key to a preset.
Ability to be direct switch or momentary switch (ie holding down keyboard (a) will POST the assigned preset.

9.2 Spotify API - View song, Play/Pause, Next track.

Environment(New): Web page banner, like Soundcloud
Via Spotify API get users current track.
Front end banner displays Spotify User's Currently Playing Track, with buttons for Play/Pause, Next track.

9.3 Spotify API - song + right time = output API

I have a Pi4, ledfx seems to work but as soon as I try an interactive pattern it terminates.

I have tried two different USB microphones, both have the same outcome.

Hi,
thanks for your great work - with Windows/Anaconda everything is running fine, the combination with WLED looks awesome.

Now i tried to use my Raspberry Pi, installation with miniconda went smooth, the webserver starts and i can add WLED devices.

But when activating devices the following error occurs - i'm using a USB mic with the following settings in .asoundrc and added the user pi to the audio group.

Hi,

First, just like to say this project is amazing! Good job! I'm just noticing the effects specifically the scroll effect is not the same as the original. The one by @not-matt (Systematic-LEDs) is a lot smoother and looks nicer. I know there are settings to tweak but I can't seem to perfect it. I tried his fork but the same problem persists.

Thanks in advance,

Hi.
I have an LED Strip directly connected to an Raspberry pi 3b Pin 18(GPIO5), controlled via
Scott’s audio-reactive-led-strip. working good.
Now i wanted to try LedFx, got the software running on the Raspberry but
have Problems to get the LEDs lit.

As writen in the wiki i did

• Add the device as a UDP
• Click ‘Additional Properties’ and check ‘Include Indexes’

but what to enter for UDP-Port? and hostname?
entering the IP of the Raspberry and some random udp port does not lead to success.

Any hints? Thanks!

Specifically the firmware offered by https://github.com/Aircoookie/WLED/ for esp8266 devices.

Googled for solutions but didn't finde anythin usefull. I'm quite new to python.

Using python 3.7.3, setuptools 41.0.1

Any help is appreciated.

The project works fine when doing audio effects, however it uses my mic as the input. I would like to choose the system sounds as the input, this way I'd be able to use Spotify or whatever music player to actually be the input.

Thanks in advance!

I saw this neat fireworks effect on reddit (includes sample code):
https://www.reddit.com/r/arduino/comments/c3sd46/i_made_this_fireworks_effect_for_my_led_strips/

Something like this could look really cool synchronized to music.

Hey, on my Odroid device the default audio device doesn't seem to work for input. Doesn't look like there's a config value for specifying one in particular.

I've used arecord -L to list my devices and arecord -D plughw:CARD=Device,DEV=0 -f cd -d 0 -vv /dev/null to test monitoring the levels with success.

Hi again,

seems there’s still some work to do.

• WebUI looks simple (no CSS?)
  
• Where do I find a hint what’s supposed to go into "Effects config"?
• Upon each and every effect, a 405: Method Not Allowed is returned.
• Upon first run, after creating the default config,yaml, it responds (due to creating a config with no devices):

Hi everybody,

I just heard about this project and it sounds super fun! Unfortunately, I cannot install it. When I run (sudo) pip install ledfx, it will collect multiple requirements (and/or check whether they have already been satisfied), then stop with this error

Requirement already satisfied: MarkupSafe>=0.23 in /usr/lib/python3.8/site-packages (from jinja2>=2.7->aiohttp-jinja2==1.0.0->ledfx) (1.1.1)

  Found existing installation: PyYAML 5.1.2
ERROR: Cannot uninstall 'PyYAML'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.

Apparently, PyYAML 5.1.2 is already installed on my system; it has been installed by distutils and therefore I am not comfortable manually trying to uninstall it so that pip can start fresh. However, since it is already installed, why should it be uninstalled, anyway?

I am running Arch Linux 5.3.11 x86_64 on an Intel NUC. Usually don't have problems with pip at all.

What can I do to fix this? Thank you for your solutions :)

Not sure if this is perfect but it worked for me.
After hours and hours of trying to get it going on my Pi 4 I finally did.
Not wanting to break it I thought I would try on a fresh image of Raspbian on a spare Pi 3 B.
After several attempts I have documented a process that works. I've done it from a fresh Raspbian image twice to make sure. So here is my process that works. If anyone else using this gets it to work let me know.
Open a Terminal window.

wget https://github.com/jjhelmus/berryconda/releases/download/v2.0.0/Berryconda3-2.0.0-Linux-armv7l.sh
chmod +x Berryconda3-2.0.0-Linux-armv7l.sh
sudo ./Berryconda3-2.0.0-Linux-armv7l.sh

NOTE need to change install location to
/home/pi/berryconda3/

sudo nano /home/pi/.bashrc
NOTE need to add:
export PATH="/home/pi/berryconda3/bin:$PATH"
to the end of the file and save

sudo reboot -h now
conda create -n ledfx  
source activate ledfx
sudo chown pi:pi -R /home/pi/berryconda3/
pip install Cython
sudo apt-get install portaudio19-dev
pip install ledfx
ledfx --open-ui

It will open the UI
The next time you want to use it you need activate the environment with

source activate ledfx
ledfx --open-ui

Good luck

Hi, really cool project.
I've completed installation on Debiun 10, when I start it, it starts the web server, but on address 127.0.0.1, how do I get it to bind to a different interface?

I’m just trying to test this, because I like the ideas behind it (see my comments at not-matt/Systematic-LEDs#3 (comment)).

I’m currently working on a Linux Mint 19 (→ Ubuntu 18.04 → Debian) system and can’t get it installed—it claims it needs some pywin module:

Searching for pywin32>=223
Reading https://pypi.org/simple/pywin32/
No local packages or working download links found for pywin32>=223
error: Could not find suitable distribution for Requirement.parse('pywin32>=223')

(Not to myself: Seems to require Python 3.)

Hey!

When trying to install ledFX I get following error:

~/LedFx$ pip install ledfx
Collecting ledfx
Could not find a version that satisfies the requirement ledfx (from versions: )
No matching distribution found for ledfx

Any idea?

Hello,
I use a RPi with Kodi as a Musicplayer. Is it possible to run Kodi and LedFx on the same RPi?

Hello!

Awesome to see this project happening!

Was wondering - audio setup should be the same as https://github.com/not-matt/Systematic-LEDs ? any additional setting required?

how do I install on Raspberry Pi.

I get error that no suitable version found.

Raspbian Buster-lite.

Installing ledfx seems to have succeeded but upon trying to start ledfx I get the following errors:

IMPORTANT: PLEASE READ THIS FOR ADVICE ON HOW TO SOLVE THIS ISSUE!

Importing the numpy c-extensions failed.

• Try uninstalling and reinstalling numpy.

• If you have already done that, then:

  1. Check that you expected to use Python3.7 from "/usr/bin/python3",
     and that you have no directories in your PATH or PYTHONPATH that can
     interfere with the Python and numpy version "1.17.4" you're trying to use.
  2. If (1) looks fine, you can open a new issue at
     https://github.com/numpy/numpy/issues. Please include details on:
     • how you installed Python
     • how you installed numpy
     • your operating system
     • whether or not you have multiple versions of Python installed
     • if you built from source, your compiler versions and ideally a build log

• If you're working with a numpy git repository, try git clean -xdf
  (removes all files not under version control) and rebuild numpy.

Note: this error has many possible causes, so please don't comment on
an existing issue about this - open a new one instead.

Original error was: libf77blas.so.3: cannot open shared object file: No such file or directory

Any ideas if this is possible?
The Linux version does not work and as the windows version uses pywin32 that won't work either.

somebody can guide me in how can i set up the led strips im using an esp8622

Hello,
I got LedFX on my Raspberry Pi 4 Working, but it use 60% of the cpu.

Is this normal?

If Not, how i can fix the high usage of cpu?

I have some H801 (RGB2W) controllers lying around and plan to use them with penfold42’s ESPixelBoard.

I’d use these to control:

• a "dumb" RGB strip
• an additional "black light" strip on White 1
• an additional "warm white" strip on White 2 (mainly for room lighting)

So I’m thinking it’d be nice to use audio control for other-than-RGB DMX devices, like

• 4 channels on a H801 (RGB + black light)
• 3 channels on a H801 (RGB)
• 1 channel on a H801 (white, for strobe other other effects)
• 1 channel on general DMX devices, like PAR 16/36/64 stage lights, strobe, fog machine, etc.

I do assume it should be possible to consolidate any number of mel bands into any number of channels, right? Could the live visualizer handle arbitrary channel configurations?

Could some good soul port this to MacOS? I've tried installing using the Linux installation docs but to no avail.

This affects 0 volume inputs , e.g. from virtual audio devices (direct playback from audio output). Occured while routing audio with Volume Control from PulseAudio in Linux.

Affected Code in ledfx/effects/audio.py:
self._volume = aubio.db_spl(self._raw_audio_sample) self._volume_filter.update(self._volume) - line 155-156

If you look up aubio.db_spl function https://aubio.org/manual/latest/py_utils.html, it is calculating the Sound Pressure Level by using log - resulting in -inf, if 0 input volume is provided, which is then used to update the volume_filter

Once -inf is applied to ExpFilter Implementation of Scott Lawson it will keep this value, even if volume rises again after an 0 volume intput (song change, ...) -> disabling all further audio processing, since -inf is always smaller than the min_volume (default -70)

if self._volume_filter.value > self._config['min_volume']: #process audio

Possible Solution:
Add a check between lines 155 to 156:
if self._volume < self._config['min_volume']: self._volume = -0.1 # set it to other value than -inf

Hi,

Thanks for a great program! I had this setup and working on windows 10 for some time. The other day I started ledfx from anaconda terminal as usual and deleted all devices, as I wanted to start from scratch since the IP's have changed. LedFX crashed and when I tried to restart, I get the following error:

During handling of the above exception, another exception occurred:

It looks like possibly "C:\Windows\system32\seamonkey.WSF" is missing. I tried restarting the computer and even tried to restore the whole env/ledfx folder, from a backup, but still get the error. Any help is greatly appreciated.

How to fix that?

Any idea?

Thanks Stefan

On the latest raspbian stretch i get the following error after install

Looks like there are some issues with setuptools which can cause "ledfx" to fail with "Failed to create process." This will only occur if your python install path contains spaces. You can workaround this by using a virtual python environment such as anaconda or using virtualenvwrapper:

$ pip install virtualenvwrapper-win # virtualenvwrapper if not Windows
$ mkvirtualenv ledfx
(ledfx) $ pip install ledfx
(ledfx) $ ledfx --open-ui

Then, when you need to launch from a new shell first run:
$ workon ledfx

Will continue to look into the issue to make it more seamless.

Two things.

in ledfxcontroller\devices_init_.py", line 151, in create_from_config
name = device_config.get('type'))
AttributeError: 'str' object has no attribute 'get'

Changed to:
name = type(device_config))

Now error is:
ledfxcontroller\utils.py", line 196, in create
name, self._cls.name.lower()))
AttributeError: Couldn't find '<class 'str'>' in the device registry

Which I imagine is linked to what you mentioned about the config file needing fixing.
