EirLabSoundAndLights

Configuration :

Light and sound configuration :

• Install qjackctl with the command sudo apt-get install qjackctl
• Install Tkinter with the command apt install python3-tk
• Install all the dependencies with the command pip install -r <requirements.txt>

Configuration you need to do in order to launch the lights without sudo (a must if you want sound + lights) :

Needs: to not be connected to the lights while doing this

First, do this:

• sudo usermod -aG dialout your_username_on_your_laptop
• sudo usermod -aG tty your_username_on_your_laptop
• sudo usermod -aG plugdev your_username_on_your_laptop
• Create file '/etc/modprobe.d/scarlett.conf' and write 'options snd_usb_audio device_setup=1' in it

Now, restart your laptop

Plug your USB/DMX module Then, do the command lsusb

Check for the line containing "Future Technology Devices International" (or "FTDI"). On my laptop this line appears like :

"Bus 003 Device 002: ID 0403:6001 Future Technology Devices International, Ltd FT232 Serial (UART) IC"

The 2 values with 4 digits in bold are what you need to remember (here 0403 and 6001 for me, but maybe not for you)

Then, do sudo nano /etc/udev/rules.d/99-ftdi.rules

Add the line SUBSYSTEM=="usb", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", MODE="0666"

Replace "0403" and "6001" by your own values you got earlier

Then save and exit

Then unplug your USB to DMX module

Then execute this command line sudo udevadm control --reload-rules

Finally, you can replug your USB to DMX module.
