Constructor & Destructor Documentation

◆ Adafruit_EyeLights_Ring_Base()

Adafruit_EyeLights_Ring_Base::Adafruit_EyeLights_Ring_Base	(	void *	parent,
		bool	isRight
	)

Constructor for EyeLights LED ring. This is a base class used by both the direct and buffered variants. Not invoked by user code.

Parameters

parent	void* pointer to parent EyeLights object this is attached to (may be direct or buffered, hence void* rather than specific type).
isRight	true if right ring, false if left.

Note: Constructor is here in the .cpp instead of the .h because it references the static tables above.

Member Function Documentation

◆ numPixels()

uint8_t Adafruit_EyeLights_Ring_Base::numPixels ( void ) const

inline

Return number of LEDs in ring (a la NeoPixel)

Returns: int Always 24.

◆ setBrightness()

void Adafruit_EyeLights_Ring_Base::setBrightness ( uint8_t b )

inline

Set brightness of LED ring. This is a mathematical brightness scale applied to setPixel() colors when setting ring pixels, distinct from any value passed to setLEDscaling() functions, because matrix and rings share pixels.
