Add tud_midi_n_demux_stream_read() which returns the cable number of the data that was actually read. It peeks at each USB-MIDI event packet header before consuming it and stops when the next packet belongs to a different cable, allowing callers to dispatch per-cable without losing data. Implementation details: - Mirrors the host-side tuh_midi_stream_read() approach: tu_edpt_stream_peek for cable inspection, CIN-based byte count (USB MIDI 1.0 Table 4-1), leftover handling via existing midi_driver_stream_t - *p_cable_num initialized to 0xff sentinel so callers can detect "no data" even when return value is 0 - Cable-change check (total_read > 0 guard) covers both leftover-originated reads and freshly consumed packets - TU_VERIFY uses explicit != NULL comparisons, consistent with codebase style - Note: shares stream->buffer with tud_midi_n_stream_read(); do not mix calls on the same interface - Adds single-interface convenience wrapper tud_midi_demux_stream_read() Closes #1838 --- src/class/midi/midi_device.c | 102 +++++++++++++++++++++++++++++++++++++++++++ src/class/midi/midi_device.h | 12 +++++ 2 files changed, 114 insertions(+) (limited to 'src/class') diff --git a/src/class/midi/midi_device.c b/src/class/midi/midi_device.c index 023a81595..a49cd725b 100644 --- a/src/class/midi/midi_device.c +++ b/src/class/midi/midi_device.c @@ -168,6 +168,108 @@ uint32_t tud_midi_n_stream_read(uint8_t itf, uint8_t cable_num, void *buffer, ui return total_read; } +// Note: this function shares stream->buffer with tud_midi_n_stream_read(). +// Do not mix calls to both functions on the same interface. +uint32_t tud_midi_n_demux_stream_read(uint8_t itf, uint8_t *p_cable_num, void *buffer, uint32_t bufsize) { + TU_VERIFY(p_cable_num != NULL && buffer != NULL && bufsize > 0, 0); + + midid_interface_t *p_midi = &_midid_itf[itf]; + midi_driver_stream_t *stream = &p_midi->stream_read; + tu_edpt_stream_t *ep_str = &p_midi->ep_stream.rx; + + uint8_t *buf8 = (uint8_t *)buffer; + uint32_t total_read = 0; + + // Initialize to invalid cable so callers can detect "no data" even when + // the return value is 0. + *p_cable_num = 0xff; + + // If there are leftover bytes from a previous partial read, return them first + if (stream->total > 0) { + *p_cable_num = (stream->buffer[0] >> 4) & 0x0f; + const uint8_t count = (uint8_t)tu_min32((uint32_t)(stream->total - stream->index), bufsize); + TU_VERIFY(0 == tu_memcpy_s(buf8, bufsize, stream->buffer + 1 + stream->index, count)); + + total_read += count; + stream->index += count; + buf8 += count; + bufsize -= count; + + if (stream->total == stream->index) { + stream->index = 0; + stream->total = 0; + } + + if (bufsize == 0) { + return total_read; + } + } + + while (bufsize > 0) { + // Peek at next packet header to get cable number without consuming + uint8_t one_byte; + if (!tu_edpt_stream_peek(ep_str, &one_byte)) { + break; + } + + const uint8_t next_cable = (one_byte >> 4) & 0x0f; + + // Stop if cable changed (covers both leftover-originated reads and + // freshly consumed packets — total_read > 0 in either case) + if (total_read > 0 && next_cable != *p_cable_num) { + break; + } + *p_cable_num = next_cable; + + // Consume the packet + if (!tud_midi_n_packet_read(itf, stream->buffer)) { + break; + } + + const uint8_t code_index = stream->buffer[0] & 0x0f; + uint8_t msg_bytes; + + // MIDI 1.0 Table 4-1: Code Index Number Classifications + switch (code_index) { + case MIDI_CIN_MISC: + case MIDI_CIN_CABLE_EVENT: + // Reserved and unused, skip this packet + continue; + + case MIDI_CIN_SYSEX_END_1BYTE: + case MIDI_CIN_1BYTE_DATA: + msg_bytes = 1; + break; + + case MIDI_CIN_SYSCOM_2BYTE: + case MIDI_CIN_SYSEX_END_2BYTE: + case MIDI_CIN_PROGRAM_CHANGE: + case MIDI_CIN_CHANNEL_PRESSURE: + msg_bytes = 2; + break; + + default: + msg_bytes = 3; + break; + } + + const uint8_t count = (uint8_t)tu_min32((uint32_t)msg_bytes, bufsize); + TU_VERIFY(0 == tu_memcpy_s(buf8, bufsize, stream->buffer + 1, count)); + + total_read += count; + buf8 += count; + bufsize -= count; + + if (count < msg_bytes) { + // Output buffer full, save remaining for next call + stream->total = msg_bytes; + stream->index = count; + } + } + + return total_read; +} + bool tud_midi_n_packet_read(uint8_t itf, uint8_t packet[4]) { midid_interface_t *p_midi = &_midid_itf[itf]; tu_edpt_stream_t *ep_str = &p_midi->ep_stream.rx; diff --git a/src/class/midi/midi_device.h b/src/class/midi/midi_device.h index ddbc2f9f0..b80ad544a 100644 --- a/src/class/midi/midi_device.h +++ b/src/class/midi/midi_device.h @@ -66,6 +66,13 @@ uint32_t tud_midi_n_available(uint8_t itf, uint8_t cable_num); // Read byte stream (legacy) uint32_t tud_midi_n_stream_read(uint8_t itf, uint8_t cable_num, void *buffer, uint32_t bufsize); +// Read byte stream with cable demultiplexing: returns the cable number of the +// data that was read.
