Driver (components/el512/el512_panel.*, ESP-IDF only): - DMA ring of 8 x 4 lines (17 KB) refilled from the I2S EOF interrupt (IRAM) instead of a 142 KB full-frame stream; ~107 KB heap freed. - 256-entry lookup table encodes 8 pixels per step. - Back buffer + displayed buffer, swapped at the start of a frame. - PlatformIO builds it via lib_extra_dirs (EL512Core); lib/EL512 keeps the Adafruit GFX front end. ESPHome external component (platform: el512): - DisplayBuffer with optional ENABLE / _LOWPWR pins, set_enabled(), set_low_power(), helper functions for page lambdas. - still_alive_page: plays the Portal end-credits show, then returns to the previous page. Still Alive engine moved to components/el512/still_alive.* with a built-in 5x7 font (from Adafruit GFX, BSD); the PlatformIO demo uses the same code. The importer writes components/el512/still_alive_data.h and stops at 200 s (--until-ms), matching the hand-trimmed data. esphome/el512-panel.yaml: 8 pages (clock, forecast, agenda, dashboard, now playing, Plex, solar, Still Alive), page select, rotation, display and low-power switches, message text. home_assistant/packages/el512_panel.yaml: helper template sensors for forecast, agenda, now playing and Plex streams.
