The Blinkstick family of products are "Smart LED controllers with integrated USB firmware." They register as USB HID devices so Linux doesn't recognize them as part of the LED class. This daemon uses the Linux user space LED driver to bridge the gap.
I use it to bring some "blinking lights" to x86-based router devices running OpenWRT, such as the Protectli, but it is generic enough for any Linux machine.
bluld makes the assumption that only one blinkstick device is connected. At launch time you must give it the number of
LEDs on your Blinkstick as well as the colors you would like them to be. You can use friendly color names, or pass a hex
value that MUST be prepented with #. (A list of friendly colors that bluld knows is at the bottom of this README.) In
the event that blulb cannot understand the color value passed, it will default to red.
Example:
# bluld 5 aqua indigo olive yellow #010203
When bluld is running, you will see an entry for each LED in /sys/class/leds named blinkstick:<number> where
number is the number of the led, as in blinkstick:2. From there, you can use the Blinkstick LEDs like any other
registered LED.
