Detailed Description

MIDI protocol support.

Stream-based MIDI parser with running status, real-time passthrough, SysEx handling, and channel filtering. Template-based input polling.

expected_data_bytes()

uint8_t sbl::midi::expected_data_bytes ( uint8_t  status )

Here is the caller graph for this function:

poll()

template<typename UartDriver >

void sbl::midi::poll ( Parser &  parser )

inline

Poll UART for MIDI bytes and feed them to the parser.

Drains all available bytes from the UART RX buffer. Non-blocking — returns immediately if no data available.

Template Parameters

UartDriver

UART driver class with available() and read_byte()

Note

ISR-safe — drains available bytes from ring buffer, no blocking.
