29 * Structure of the LED array
31 * cRGB: RGB for WS2812S/B/C/D, SK6812, SK6812Mini, SK6812WWA, APA104, APA106
32 * cRGBW: RGBW for SK6812RGBW
35 struct cRGB { uint8_t g; uint8_t r; uint8_t b; };
36 struct cRGBW { uint8_t g; uint8_t r; uint8_t b; uint8_t w;};
43 * ledarray: An array of GRB data describing the LED colors
44 * number_of_leds: The number of LEDs to write
45 * pinmask (optional): Bitmask describing the output bin. e.g. _BV(PB0)
47 * The functions will perform the following actions:
48 * - Set the data-out pin as output
49 * - Send out the LED data
50 * - Wait 50�s to reset the LEDs

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