Python Script Interface For Luxafor

Luxafor Python Script

Script written to modify the Luxafor USB LED indicator via command line using python.

Any and all improvements welcome and appreciated.

Credit to gist by dave-irvine for pyusb code.

Requirements

Linux

1. Luxafor LED Indicator
2. Python 2.7+
3. PyUSB

Windows

1. Luxafor LED Indicator
2. Luxafor Software
3. Python 2.7+
4. PyWinUSB (installable via pip)

Confirmed Working Operating Systems

• Windows 10
• Ubuntu 15.10

Known/Possible Issues

Linux

• Sometimes first run doesn't work, have to run command a second time

Allow usb permissions for python in Ubuntu 16.04

By default python will not let use usb libs and you will need to run command with sudo everythime. Let's no do that.

• find out device with lsusb. Should be something like 04d8:f372 where 04d8 is vendor id and f372 is product id.
• create file /lib/udev/rules.d/50-luxafor.rules

ACTION=="add", SUBSYSTEMS=="usb", ATTRS{idVendor}=="VENDOR_ID", ATTRS{idProduct}=="PRODUCT_ID", MODE="660", GROUP="plugdev"

• Reload rules:
  • sudo udevadm control --reload
  • sudo udevadm trigger
• Unplug and replug the device or reboot your machine

Windows

• Seems the Luxafor app has to be at least running in the tray for commands to persist
• Opening the Luxafor app switches the color to Green/Red (depeding on last used?)
• Seems that it doesn't always return to the exact same state it was in before a strobe or pattern is ran

Parameters

-l = LED - 1-6 for specific LED, 65 for front, 66 for back, 0 for all, 255 for all one color
-r = RED value (0-255)
-g = GREEN value (0-255)
-b = BLUE value (0-255)
-s = Speed value - Determines speed of strobe or fade (0-255)
-t = Repeat value - Determines the frequency of strobe or wave (0-255)
-w = Wave value - 5 Different Patterns available (1-5)
-p = Built In Patterns - 8 built in patterns -x = Hex color value - ("#RRGGBB")
