3.7.7

What's Changed

• WS2812 RGBW mode is now part of the API.
  • Api: FastLED.addLeds<WS2812, DATA_PIN, GRB>(leds, NUM_LEDS).setRgbw(RgbwDefault());
  • Only enabled on ESP32 boards, no op on other platforms.
  • See examples/RGBW/RGBW.ino
• WS2812 Emulated RGBW Controller
  • Works on all platforms (theoretically)
  • Has an extra side buffer to convert RGB -> RGBW data.
    • This data is sent to the real driver as if it were RGB data.
    • Some padding is added when source LED data is not a multiple of 3.
  • See examples/RGBWEmulated/RGBWEmulated.ino
• New supported chipsets
  • UCS1912 (Clockless)
  • WS2815 (Clockless)
• New supported boards
  • xiaoblesense_adafruit
    • Fixes #1445
• PixelIterator has been introduced to reduce complexity of writing driver code
  • This is how RGBW mode was implemented.
  • This is a concrete class (no templates!) so it's suitable for driver code in cpp files.
  • PixelController<> can convert to a PixelIterator, see PixelController<>::as_iterator(...)
• Fixed APA102HD mode for user supplied function via the linker. Added test so that it won't break.
