Utilities

RangeScale

Scales a value from one range to another range.

RangeScale scale(fromMin, fromMax, toMin, toMax);

float toValue = scale.convert(fromValue);

CycleEnum

Cycles through a list of enums. Useful to make a rotary encoder cycle through an enumerated list of modes. e.g.

enum Mode {
    FIRST_MODE,
    SECOND_MODE,
    LAST_MODE
};

CycleEnum<Mode> mode = CycleEnum<Mode>(FIRST_MODE, LAST_MODE); //first and last modes in enum

Cycle using RotaryEncoder:

if(encoder.update()) {
    mode.cycle(encoder.getMovement());
}

Get value of enum using mode.value
