LED Layouts

Some examples are written for a specific LED layout or art project, some examples are general-purpose. For examples that use a specific LED layout, we indicate this with a naming convention. For example, if a project "potato" were written for a 48x24 grid, it would be named "grid48x24_potato".

Some of the generic examples (Specifically, the C++ and Node.js ones) can load separate layout files. These are in the same JSON notation used by the Open Pixel Control project, and we use the same naming scheme for those JSON files.

Layout names we use so far:

  • grid8x8 - A simple left-to-right top-to-bottom 8x8 pixel grid
  • grid24x8z - Three 8x8 zig-zag grids side by side
    • Channel 0 is the center, and may be used alone.
    • For example, three of the 8x8 grids from RGB-123
  • grid32x8z - A 4x2 grid of 8x8 zig-zag grids
    • Channel 0 is the top-left grid, channel 7 is the bottom-right
    • For example, eight of the 8x8 grids from RGB-123
  • strip64 - A single 64-pixel LED strip
  • triangle16 - A subdivided equilateral triangle with 16 pixels
  • window6x12 - A complex window display layout made from glass blocks
    • This example shows how additional properties other than location may be stored in the JSON file.
