Detailed Description

PROGMEM melody data for SH2SC-EDT — Transmitter Node A.

Part of the SH2SC-EDT project. Implements the C2P-ARQ protocol.

     THIS FILE IS AUTO-GENERATED by tools/midi_to_cpp.py.
     Do NOT edit by hand — re-run the script to regenerate from MIDI.

     **Table format:** @c melody[][2]
     - Column 0 — note index (@c uint16_t):
       - 0–20  = chromatic pitches C4…G#5 (mapped in @c universal_notes[] on RX).
       - 255   = REST_INDEX — silence for the specified duration.
     - Column 1 — duration in milliseconds (@c uint16_t).

     Source MIDI: The_Imperial_March-Star_Wars.mid
     Melody name: Star Wars — Imperial March

     Flash usage: MELODY_LENGTH * 4 bytes (two uint16_t per row).

Variable Documentation

melody

const uint16_t melody[MELODY_LENGTH][2]

static

PROGMEM melody table — note indices and durations for the Imperial March.

Stored in Flash (PROGMEM) to avoid consuming 2120 bytes of SRAM. Access via pgm_read_word(&melody[i][col]) — do NOT dereference directly.

• melody[i][0]: note index (0–20 or REST_INDEX=255).
• melody[i][1]: duration in milliseconds.

MELODY_LENGTH

const uint16_t MELODY_LENGTH = 530

static

Total number of note/rest entries in the PROGMEM melody table.

Flash usage: MELODY_LENGTH * 4 bytes = ~2120 bytes of Flash.
