// MATRIX DECLARATION: | |
// Parameter 1 = width of NeoPixel matrix | |
// Parameter 2 = height of matrix | |
// Parameter 3 = pin number (most are valid) | |
// Parameter 4 = 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 matrix; pick two, e.g. | |
// NEO_MATRIX_TOP + NEO_MATRIX_LEFT for the top-left corner. | |
// NEO_MATRIX_ROWS, NEO_MATRIX_COLUMNS: LEDs are arranged in horizontal | |
// rows or in vertical columns, respectively; pick one or the other. | |
// NEO_MATRIX_PROGRESSIVE, NEO_MATRIX_ZIGZAG: all rows/columns proceed | |
// in the same order, or alternate lines reverse direction; pick one. | |
// See example below for these values in action. | |
// Parameter 5 = pixel type flags, add together as needed: | |
// NEO_KHZ800 800 KHz bitstream (most NeoPixel products w/WS2812 LEDs) | |
// NEO_KHZ400 400 KHz (classic 'v1' (not v2) FLORA pixels, WS2811 drivers) | |
// NEO_GRB Pixels are wired for GRB bitstream (most NeoPixel products) | |
// NEO_RGB Pixels are wired for RGB bitstream (v1 FLORA pixels, not v2) | |
// Example for NeoPixel Shield. In this application we'd like to use it | |
// as a 5x8 tall matrix, with the USB port positioned at the top of the | |
// Arduino. When held that way, the first pixel is at the top right, and | |
// lines are arranged in columns, progressive order. The shield uses | |
// 800 KHz (v2) pixels that expect GRB color data. | |
