LED-Stalker

The StalkerEffect plugin provides an interesting new typing experience: the LEDs light up as you tap keys and play one of the selected effects: a haunting trail of ghostly white lights, or a blazing trail of fire.

Using the plugin

To use the plugin, one needs to include the header and select the effect.

#include <Kaleidoscope.h>
#include <Kaleidoscope-LEDControl.h>
#include <Kaleidoscope-LED-Stalker.h>

KALEIDOSCOPE_INIT_PLUGINS(LEDControl, StalkerEffect);

void setup (){
  Kaleidoscope.setup();

  StalkerEffect.variant = STALKER(Haunt, (CRGB(0, 128, 0)));
  StalkerEffect.activate();
}

It is recommended to place the activation of the plugin (the Kaleidoscope.use call) as early as possible, so the plugin can catch all relevant key presses. The configuration can happen at any time and should use the STALKER macro to do so.

Plugin methods

The plugin provides the StalkerEffect object, which has the following properties:

.variant

Set the effect to use with the plugin. See below for a list.

It is recommended to use the STALKER macro to declare the effect itself.

.step_length

The length - in milliseconds - of each step of the animation. An animation lasts 256 steps.

Defaults to 50.

.inactive-color

The color to use when a key hasn't been pressed recently.

Defaults to (cRGB) { 0, 0, 0 }

Plugin helpers

STALKER(effect, params)

Returns an effect, to be used to assign a value the .variant property of the StalkerEffect object. Any arguments given to the macro are passed on to the effect. If the effect takes no arguments, use an empty params list.

Plugin effects

The plugin provides the following effects:

Haunt([color])

A ghostly haunt effect, that trails the key taps with a ghostly white color (or any other color, if specified). Use the CRGB(r,g,b) macro to specify the color, if you want something else than the ghostly white.

BlazingTrail()

A blazing trail of fire will follow our fingers!

Rainbow()

Leave a rainbow behind, where your fingers has been!
