function 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)

---

function Led

inline daisy::Led::Led () 

---

function 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.

---

function SetSampleRate

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

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

Parameters:

• sample_rate New update rate in hz.

---

function Update

void daisy::Led::Update () 

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

---

function ~Led

inline daisy::Led::~Led ()
