NoteCCKPRangeFastLED< Type, RangeLen, ColorMapper > Class Template Referenceabstract

#include <MIDI_Inputs/LEDs/NoteCCKPRangeFastLED.hpp>

Detailed Description

template<MIDIMessageType Type, uint8_t RangeLen, class ColorMapper>
class NoteCCKPRangeFastLED< Type, RangeLen, ColorMapper >

Generic base class for classes that listen for MIDI Note, Control Change and Key Pressure events on a range of addresses and turns on the corresponding LED in a FastLED strip with a color that depends both on the index in the range and the value of the incoming MIDI message.

Template Parameters
TypeThe type of MIDI messages to listen for:
RangeLenThe length of the range of addresses to listen to.
ColorMapperA callable that maps a 7-bit MIDI value and the index in the range to a FastLED CRGB color, see DefaultColorMapper for an example.
Examples
10.Note-FastLED-ColorMapper.ino, and 9.Note-FastLED.ino.

◆ setBrightness()

void setBrightness ( uint8_t  brightness)
inline

Set the maximum brightness of the LEDs.

Parameters
brightnessThe maximum brightness [0, 255]

Definition at line 110 of file NoteCCKPRangeFastLED.hpp.

◆ getBrightness()

uint8_t getBrightness ( ) const

◆ setLEDIndexPermuter()

void setLEDIndexPermuter ( index_permuter_f  permuter)
inline

Change the mapping from the MIDI index to the LED index.

The MIDI index is derived from the note or controller number.

The function should take the (zero-based) MIDI index value as a parameter, and return the corresponding LED index (zero-based). By default, the LED index is the same as the MIDI index.

Definition at line 123 of file NoteCCKPRangeFastLED.hpp.
