Public Member Functions
void	set_callback (MidiCallback cb)
	Set the callback for parsed MIDI events.
void	set_channel (uint8_t ch)
	Set channel filter.
void	push (uint8_t byte)
	Feed one byte from UART RX.
void	push (const uint8_t *data, uint16_t len)
	Feed multiple bytes.

Detailed Description

MIDI byte stream parser — state machine with running status.

Note

All public methods are ISR-safe — O(1) state machine with no hardware I/O. Callback is invoked synchronously from push().

Definition at line 35 of file parser.hpp.

Member Function Documentation

push() [1/2]

void sbl::midi::Parser::push ( const uint8_t *  data, uint16_t  len  )

inline

Feed multiple bytes.

Note

ISR-safe — O(n) loop over push(), no blocking or I/O.

Definition at line 158 of file parser.hpp.

References push().

Here is the call graph for this function:

push() [2/2]

void sbl::midi::Parser::push ( uint8_t  byte )

inline

Feed one byte from UART RX.

State machine processes the byte and dispatches complete messages via the callback. System Real-Time messages are dispatched immediately, even mid-message.

Note

ISR-safe — O(1) state machine, no blocking or I/O.

Definition at line 59 of file parser.hpp.

Here is the caller graph for this function:

set_callback()

void sbl::midi::Parser::set_callback ( MidiCallback  cb )

inline

Set the callback for parsed MIDI events.

Note

ISR-safe — stores a function pointer, no I/O.

Definition at line 41 of file parser.hpp.

set_channel()

void sbl::midi::Parser::set_channel ( uint8_t  ch )

inline

Set channel filter.

Parameters

ch	Channel 0-15, or 0xFF for omni (receive all channels)

Note

ISR-safe — stores a byte, no I/O.

Definition at line 48 of file parser.hpp.
