LED Preferences
The sound reactive fork of WLED supports multiple layouts of a 2D matrix led panel as well as multiple identical 2D matrix led panels. Many effects were written with a 16x16 panel in mind, so some 2D effects may not display properly on a panel/matrix of a different size.
2D effects are projected on a 2 dimensional matrix.
A specific led is identified by led[x,y] where led[0,0] is in the top left corner (logical layer)
| Setting name | Value Range | Description | Master/Dev |
|---|---|---|---|
| Width | 1..x | Width of the matrix | Master |
| Height | 1..y | Height of the matrix | Master |
Note: width x height should match LED count!
A matrix is made of 1 or more identical physical led panels (physical layer)
| Setting name | Value Range | Description | Master/Dev |
|---|---|---|---|
| Multiple panels | Y/N | No if only one panel, yes if more than one | Dev |
| Horizontal panels | 1..x | Number of panels side by side | Dev |
| Vertical panels | 1..y | Number of panels above each other | Dev |
Note: Panel width = matrix width / horizontal panels and panel height = matrix height / vertical panels
Note: Total panels = horizontal * vertical
Specify how a led panel is wired.
This is in most cases different from the logical layer (first led top left). Parameters here translate the logical layer (led[x,y]) to the physical layer (led[0] .. led[n]).
| Setting name | Value Range | Description | Master/Dev |
|---|---|---|---|
| First led position | Top/Bottom & Left/Right | Where is the first led positioned | Dev (replacing flipmajor/minor) |
| Orientation | Horizontal / Vertical | Are rows of leds wired horizontal or vertical | Dev (replacing rowMajor) |
| Serpentine | Y/N | Are rows of leds wired zig-zag or not | Master |
| Transpose | Y/N | Swap the axes (otherwise no swap). Don't use on non-square panels | Dev |
Note: If multiple panels are used, they must be identical.
I have 6 - 8x8 panels. They are connected sequentially with 24 led's wide and 15 led's high as follows:
0 1 2
3 4 5
