Effect Sample (see here for sample info) (Looks more teal IRL)

An effect based on the pacific code here, written by Mark Kriegsman and Mary Corey March.

A gentle effect of blue-green ocean waves rolling across the strip. The effect runs as is; there's no customization. Almost all of the code is directly copied from the original linked above. If you have any questions about how it works, please direct them to Mark Kriegsman. For a hue-based version of the effect see Pacifica Hue.

The palettes can be found in "pacificaPalette.h" in the code. I tried to adapt the original effect's FastLED palettes to Pixel Spork's palettes. Overally I think I got pretty close, although it's not 100% perfect.

Recommend brightness >80 and rate > 20ms. For low brightness values I recommend turning off dithering using FastLED.setDither(0).

The effect is 1D only. Pacifica Hue for a 2D version.

The effect is a bit computationally heavy.

Note, I've made the background color a pointer so you can bind it externally (as it is in other effects). You probably shouldn't change it tho, b/c it heavily influences the effect.

PacificaPS pacifica(mainSegments, 40);
//That's it, updates at 40ms

PacificaPS(SegmentSetPS &SegSet, uint16_t Rate);

• SegmentSetPS* segSet -- The Segment Set the effect will draw on. See common vars segSet entry for more details.

• uint16_t* rate -- Update rate (ms). Is a pointer, allowing you to bind it to an external variable. By default it's bound the effect's local variable, rateOrig. See common vars rate entry for more.

• bool showNow (default true) -- Controls if the effect "draws" during each update cycle by calling FastLED.show(). Common to all effects. See common vars showNow entry for more details.

• void update();

  Updates the effect.
