Decisions

Decisions are logged in PROJECT.md Key Decisions table. Recent decisions affecting current work:

[Roadmap]: Hardware-first build order — ESP32 is the validation target for all Pi-side work; developing against a mock risks protocol mismatches late.
[Roadmap]: WiFi+RMT coexistence must be tested on day 1 of Phase 1 (documented FastLED #1657, February 2026 — actively problematic on single-core ESP32-C3).
[Roadmap]: SK6812 is RGBW (4 bytes/LED) — configure explicitly before any animation code; retrofitting requires protocol version bump.
[Phase 01-esp32-firmware]: GPIO3 for SK6812 RMT (safe on SuperMini); GPIO6/7 for WS2801 SPI with GPIO0/1 fallback noted for JTAG conflicts
[Phase 01-esp32-firmware]: NeoWs2801Spi2MhzMethod for 5m cable signal integrity; NeoGrbwFeature for SK6812 RGBW 4-byte mode
[Phase 01-esp32-firmware]: -DESP32_ARDUINO_NO_RGB_BUILTIN mandatory in platformio.ini to prevent RMT driver conflict with Arduino core 3.x
[Phase 01-esp32-firmware]: Hardware coexistence validated: WIFI_PS_NONE eliminates RMT flicker on ESP32-C3, zero flicker confirmed during 30s UDP burst test
[Phase 01-esp32-firmware]: GPIO3/6/7 pin assignments confirmed on physical hardware — no JTAG conflicts, fallback GPIO0/1 not needed
[Phase 01-esp32-firmware]: Two-queue FreeRTOS pattern: xQueueSendFromISR in AsyncUDP callback, parseTask drains rawQueue and dispatches LedCommand to commandQueue — prevents watchdog resets from JSON heap alloc in callback
[Phase 01-esp32-firmware]: STATUS cmd handled inline in parseTask (no animation engine route) — needs sender IP/port from raw packet context, responds via udp.writeTo()
[Phase 01-esp32-firmware]: parseCommand() enforces brightness cap (max 60%) per D-09 — firmware-side safety cap regardless of Pi value
[Phase 01-esp32-firmware]: vTaskDelayUntil for 50fps drift-free animation tick — never drifts by compute time unlike vTaskDelay
[Phase 01-esp32-firmware]: autoWhite formula: min(r,g,b)/2 warm-white approximation — triggers only when W=0 on RGBW strips
[Phase 01-esp32-firmware]: initAnimationEngine() called before WiFi.begin() so startup breathing animation is visible during WiFi connect (D-11)
[Phase 01-esp32-firmware]: WIFI_PS_NONE re-applied on WiFi reconnect to prevent RMT flicker after disconnect/reconnect cycle
[Phase 01-esp32-firmware]: Hardware acceptance test approved — all 5 FW requirements (FW-01 through FW-05) validated on physical ESP32-C3 SuperMini with both LED strips
[Phase 02-app-core-audio]: asyncio DatagramProtocol with fire-and-forget sendto() for ESP32 UDP transport (D-10); v:1 injected by transport layer; connected state via STATUS ok only (D-12)
[Phase 02-app-core-audio]: D-04 applied: AudioPlayer uses miniaudio in its own OS thread, no asyncio dependencies in player.py
[Phase 02-app-core-audio]: D-09 applied: pause() saves _paused_position, resume() calls _start_device(seek_seconds=saved) for accurate seek-based resume

Pending Todos

None yet.

Blockers/Concerns

[Phase 1]: ESP32-C3 RMT+WiFi coexistence has conflicting documentation — test simultaneously on first flash.
[Phase 1]: GPIO pin assignment for simultaneous RMT (SK6812) + SPI (WS2801) on SuperMini needs hardware validation.
[Phase 2]: aubio 0.4.9 ARM pip wheel on Raspberry Pi OS bookworm unverified — may require source build.
[Phase 2]: sounddevice + miniaudio simultaneous PipeWire access needs early testing.
