Auf dem Holodeck gibt es über das Netzwerk steuerbares LED-Licht.
Diese Seite soll grob die Funktionen dokumentieren. Für eine aktuelle Dokumentation siehe in der [https://gitli.stratum0.org/chrissi/ledctl/blob/master/README.md README].

== LIGHT SETUP ==

The LED-light is divided into four sections. Two on each side. The front section is two thirds of the length, the back section is obviously one third.

Looking to the screen-side of the room:
* Section one is on the back on the left
* The folling sections are named clockwise

== Some useful defaults ==
Open one of these Links from inside the space to apply the new color. 
* [http://frickelicht.s0/holodeck/all/nicewhite warm white]
* [http://frickelicht.s0/holodeck/all/day cold white]
* [http://frickelicht.s0/holodeck/all/off nearly off]
* [http://frickelicht.s0/holodeck/all/night really off]
* [http://frickelicht.s0/holodeck/all/0.2,0,0,0 hot!]

== USAGE ==

The software exports a rudimentary web-based interface. The interface is divided into two sections:
* Section to set colors or presets
* Section to list and add/alter presets

===Setting a color===
A color is set using the following call:
<pre><nowiki>
http://frickelicht.s0/holodeck/<section>/<colorCode>
</nowiki></pre>

Where:
 <section> is all or a section number [1 .. 4]
 <color> is a color-code

Color Codes are made up of a list of float values in the range of [0.0 .. 1.0]. Depending on the number of elements the color codes are iterpreted to be in different color spaces:
 <float>: Is interpreted as brightness and creates a RGBW-mixed broad-spectrum white in the given brightness
 <float>,<float>,<float>: Is interpreted as RGB-value. The value is transformed into the RGBW color space before outputting it. Thus even a 1.0,0.0,0.0 (red) will contain some white.
 <float>,<float>,<float>,<float>: Is interpreted as RGBW-value. This value is directly outputted to the LEDs.
 <float>,<float>,<float>,<float><float>,<float>,<float>,<float><float>,<float>,<float>,<float><float>,<float>,<float>,<float> (16 floats): This special form can be used on the section code all. It is interpreted as four RGBW-color codes for the four sections. Thus with this color code a new color for all sections can be set

===Preset-types:===
There are two types of presets:
* System-presets: These presets contain all RGB-colors defined with names in CSS. These presets can not be altered. But user-presets have a highter priority.
* User-presets: These presets can be set by the user. The list has a limited length.

===Listing presets:===
Presets can be listed using the following call:
 http://frickelicht.s0/preset 

===Setting presets:===
A preset can be created or altered using the following call:
<pre><nowiki>
http://frickelicht.s0/preset/<name>/<color>
</nowiki></pre>

===Using a preset:===
A preset is set with the folowing call:
<pre><nowiki>
http://frickelicht.s0/holodeck/<section>/<presetName>
</nowiki></pre>

If a preset with colors for all four sections is applied on a section other than all only the first RGBW-value will be used on the section.
