Detailed Description¶

class daisy::Parameter;

Simple parameter mapping tool that takes a 0-1 input from an hid_ctrl.

Public Types Documentation¶

enum Curve¶

Enumerator	Value	Description
LINEAR		Linear curve
EXPONENTIAL		Exponential curve
LOGARITHMIC		Logarithmic curve
CUBE		Cubic curve
LAST		Final enum element.

Curves are applied to the output signal

Public Functions Documentation¶

function Parameter¶

inline Parameter()

Constructor

function ~Parameter¶

inline ~Parameter()

Destructor

function Init¶

void Init(
    AnalogControl input,
    float min,
    float max,
    Curve curve
)

Parameters:

input - object containing the direct link to a hardware control source.
min - bottom of range. (when input is 0.0)
max - top of range (when input is 1.0)
curve - the scaling curve for the input->output transformation.

initialize a parameter using an hid_ctrl object.

function Process¶

float Process()

Return: a float with the specified transformation applied.

processes the input signal, this should be called at the samplerate of the hid_ctrl passed in.

function Value¶

inline float Value()

Return: the current value from the parameter without processing another sample. this is useful if you need to use the value multiple times, and don't store

the output of process in a local variable.
