    Config config
)

Parameters:

config Configuration structure used to define specifics to the MIDI Handler.

Initializes the MidiHandler

function StartReceive¶

inline MidiEvent PopEvent()

Return: The event to be handled

Pops the oldest unhandled MidiEvent from the internal queue

function SendMessage¶

inline void SendMessage(
    uint8_t * bytes,
    size_t size
)

SendMessage Send raw bytes as message

function Parse¶

inline void Parse(
    uint8_t byte
)

Parameters:

byte MIDI byte to be parsed

Note: Normally application code won't need to use this method directly.
