39 * Structure of the LED array
41 * cRGB: RGB for WS2812S/B/C/D, SK6812, SK6812Mini, SK6812WWA, APA104, APA106
42 * cRGBW: RGBW for SK6812RGBW

53 * ledarray: An array of GRB data describing the LED colors
54 * number_of_leds: The number of LEDs to write
55 * pinmask (optional): Bitmask describing the output bin. e.g. _BV(PB0)
57 * The functions will perform the following actions:
58 * - Set the data-out pin as output
59 * - Send out the LED data
60 * - Wait 50�s to reset the LEDs

65 void ws2812_setleds_rgbw(LED_TYPE *ledarray, uint16_t number_of_leds);
68 * Old interface / Internal functions
70 * The functions take a byte-array and send to the data output as WS2812 bitstream.
71 * The length is the number of bytes to send - three per LED.
