Main prototype and parameters

Notes are defined using their frequency in Hertz, as you would with a simple int.

Constants

The CRC defines the following constants, which represents the standard musical notes:

• NOTE_B0

• NOTE_C1

• NOTE_CS1

• NOTE_D1

• NOTE_DS1

• NOTE_E1

• NOTE_F1

• NOTE_FS1

• NOTE_G1

• NOTE_GS1

• NOTE_A1

• NOTE_AS1

• NOTE_B1

• NOTE_C2

• …

• NOTE_DS8

The first letter (A, B, C, etc.) defines the note, the optional S denotes if the note is sharp and the number defines the octave

Note

Note is a type that includes a pitch and a duration, used for a tune played by the CrcDuino. Note::END indicates the end of the tune.

Use it as such:

// Define a tune. Notice the Note::END at the end.
const Note TUNE_METRO[]
    = { { 500, NOTE_FS4 }, { 500, NOTE_B4 }, { 800, NOTE_FS5 }, Note::END };
