Tip - Change editor

If you rather want to use vim or another editor, the file is at /home/lux-neo/userdata/config/strip.json

led_count

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

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>]

Warning

If you don't have a reference to all the segments or something, the matrix setup will fail. And fall back to 'segmentsconfiguration'

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

Warning

If using a newer RPi (3 or newer), leave this as 10! Or your file-system might crash.

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

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