// Parameter 1 = width of EACH NEOPIXEL MATRIX (not total display)
// Parameter 2 = height of each matrix
// Parameter 3 = number of matrices arranged horizontally
// Parameter 4 = number of matrices arranged vertically
// Parameter 5 = pin number (most are valid)
// Parameter 6 = matrix layout flags, add together as needed:
// NEO_MATRIX_TOP, NEO_MATRIX_BOTTOM, NEO_MATRIX_LEFT, NEO_MATRIX_RIGHT:
// Position of the FIRST LED in the FIRST MATRIX; pick two, e.g.
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner.
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs WITHIN EACH MATRIX are
// arranged in horizontal rows or in vertical columns, respectively;
// pick one or the other.
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns WITHIN
// EACH MATRIX proceed in the same order, or alternate lines reverse
// direction; pick one.
// NEO_TILE_TOP, NEO_TILE_BOTTOM, NEO_TILE_LEFT, NEO_TILE_RIGHT:
// Position of the FIRST MATRIX (tile) in the OVERALL DISPLAY; pick
// two, e.g. NEO_TILE_TOP + NEO_TILE_LEFT for the top-left corner.
// NEO_TILE_ROWS, NEO_TILE_COLUMNS: the matrices in the OVERALL DISPLAY
// are arranged in horizontal rows or in vertical columns, respectively;
// pick one or the other.
// NEO_TILE_PROGRESSIVE, NEO_TILE_ZIGZAG: the ROWS/COLUMS OF MATRICES
// (tiles) in the OVERALL DISPLAY proceed in the same order for every
// line, or alternate lines reverse direction; pick one. When using
// zig-zag order, the orientation of the matrices in alternate rows
// will be rotated 180 degrees (this is normal -- simplifies wiring).
// See example below for these values in action.
// Parameter 7 = pixel type flags, add together as needed:
// NEO_RGB Pixels are wired for RGB bitstream (v1 pixels)
// NEO_GRB Pixels are wired for GRB bitstream (v2 pixels)
// NEO_KHZ400 400 KHz bitstream (e.g. FLORA v1 pixels)
// NEO_KHZ800 800 KHz bitstream (e.g. High Density LED strip)
#include "index.html"
// Example with three 10x8 matrices (created using NeoPixel flex strip --
// these grids are not a ready-made product). In this application we'd
// like to arrange the three matrices side-by-side in a wide display.
// The first matrix (tile) will be at the left, and the first pixel within
// that matrix is at the top left. The matrices use zig-zag line ordering.
// There's only one row here, so it doesn't matter if we declare it in row
// or column order. The matrices use 800 KHz (v2) pixels that expect GRB
// color data.
