Init()

void daisy::Led::Init	(	Pin	pin,
		bool	invert,
		float	samplerate = 1000.0f
	)

Initializes an LED using the specified hardware pin.

Parameters

pin	chooses LED pin
invert	will set whether to internally invert the brightness due to hardware config.
samplerate	sets the rate at which 'Update()' will be called (used for software PWM)

Set()

void daisy::Led::Set

(

float

val

)

Sets the brightness of the Led.

Parameters

val	will be cubed for gamma correction, and then quantized to 8-bit values for Software PWM 8-bit is for more flexible update rate options, as 12-bit or more would require faster update rates.

SetSampleRate()

void daisy::Led::SetSampleRate ( float  sample_rate )

inline

Set the rate at which you'll update the leds without reiniting the led

Parameters

sample_rate

New update rate in hz.

Update()

void daisy::Led::Update

(

)

This processes the pwm of the LED sets the hardware accordingly.
