How to setup luxcena-neo to work with your setup

$ sudo lux-neo conf

When running the command above, a config file should appear in the editor 'nano'.

{
    "led_count": 53,
    "segments": [],
    "matrix": [],
    "segmentConfiguration": "snake",
    "led_pin": 18,
    "led_freq_hz": 800000,
    "led_dma": 10,
    "led_invert": false,
    "led_channel": 0
}

led_count

This is the number of LED's you want to control.

segments

This is a simple list, here you should add the lenghts of all your segments. Please enter the "real" length, and don't start counting from 0. If you just want one segment, you should just have one element in the list, which is the number of led's you are controlling.

When summing this list, it should check out with the "led-count"-option.

matrix

This is a two dimensonal array, used to arrange the segments in a matrix of your likings. Here you enter the segment-number to represent them. In the example above, all the segments are in one line. If you want to have them in a square, it could look like this:

"segments": [10, 10, 10, 10, 10, 10, 10, 10, 10],
"matrix": [
    [[0, false], [1, true], [2, false]],
    [[3, true], [4, false], [5, true]],
    [[6, false], [7, true], [8, false]]
]

Each entry looks is a list, with two parameters, [<segment_number>, <invert>]

segmentconfiguration

If the matrix-option is empty or badly setup. The matrix will be set up using one of these defaults:

"snake":
"line":
"random":

led_pin

If using the luxcena-shield, you shouldn't have to worry about this option. But set it to the GPIO-port connected to your pixel's din-port.

led_dma

led_invert

This should not be touched, unless you are using a inverting level converter.

led_channel

Leave this as default unless you know what you are doing.

Now you might want to take a look at the command line interface.
