ESP32-S31 Ode to joy
RMT on GPIO0 plays the stock Ode to joy score through a passive buzzer. Enable Sound in Settings to listen; pitches and note lengths follow the driver's integer timing. The score plays once. Enable verbose in Serial to see the stock INFO lines. Unmodified pinned ESP-IDF development source on the bounded S31 simulator profile; no physical flashing.
