|
|
patterns:
|
|
- "Subsystem launch order: LED driver first, animation engine second (startup breathing during WiFi connect), UDP server last (after WiFi)"
|
|
- "WiFi reconnect in loop(): 5s poll, re-apply WIFI_PS_NONE, restart UDP server on reconnect"
|
|
- "D-10 graceful disconnect: animation continues on WiFi loss, UDP auto-restarts on reconnect"

|
|
|
|
key-decisions:
|
|
- "initAnimationEngine() called before WiFi.begin() so startup breathing animation is visible during WiFi connect (D-11)"
|
|
- "WiFi timeout (30s) continues without network — last animation keeps running (D-10)"
|
|
- "loop() uses vTaskDelay(100ms) to yield to FreeRTOS — LED/animation tasks have full CPU priority"
|
|
- "WIFI_PS_NONE re-applied on WiFi reconnect to prevent RMT flicker after disconnect/reconnect cycle"
|
|
|
|
patterns-established:
|
|
- "Protocol version check: every command must include v:1 or is dropped silently"
|
|
- "Brightness cap: firmware enforces 60% max regardless of Pi-side value"
|
|
- "Error handling: malformed JSON/unknown commands silently dropped and logged to serial only"

# Phase 01 Plan 04: Integration and Hardware Validation Summary
|
|
|
|
**Complete ESP32 firmware wiring all subsystems (LED driver + animation engine + UDP server) into production main.cpp, hardware-validated on physical ESP32-C3 — all 5 FW requirements confirmed passing.**
|
|
|
|
## Performance
|
|
|
|
- **Duration:** ~5 min (Task 1 code + checkpoint approval on hardware)
|
|
- **Started:** 2026-04-03T11:31:34Z
|
|
- **Completed:** 2026-04-03
|
|
- **Tasks:** 2 of 2 complete (1 automated + 1 hardware acceptance checkpoint)
|
|
- **Files modified:** 2
|
|
|
|
## Accomplishments
|
|
|
|
- Replaced placeholder main.cpp loop with production FreeRTOS-compatible setup/loop
|
|
- Correct subsystem launch order: initStrips → initAnimationEngine → WiFi connect → WIFI_PS_NONE → startUdpServer
|
|
- Startup breathing animation fires during WiFi connect (D-11 compliance)
|
|
- WiFi disconnect resilience: 30s timeout continues without network, loop() auto-restarts UDP on reconnect
|
|
- docs/protocol.md: complete Phase 2 reference for all 8 animations, all commands, both zones, port 4210, error behavior
|
|
|
|
## Task Commits
|
|
|
|
1. **Task 1: Wire subsystems in main.cpp + write protocol documentation** - `530e9da` (feat)
|
|
2. **Task 2: Full system hardware acceptance test** - checkpoint approved by user (no code commit — hardware validation)
|
|
|
|
**Plan metadata:** `a737664` (docs: complete integration plan)
|
|
|
|
## Files Created/Modified
|
|
|
|
- `firmware/src/main.cpp` - Complete integrated setup()/loop(), all subsystems wired in correct order
|
|
- `docs/protocol.md` - UDP/JSON protocol reference for Phase 2 Pi-side developer
|
|
|
|
## Decisions Made
|
|
|
|
- `initAnimationEngine()` starts before WiFi so breathing animation is visible during the ~5s WiFi connect wait — users see the ESP32 is alive
|
|
- `loop()` yields with `vTaskDelay(100ms)` to FreeRTOS — LED driver (priority 3) and animation tick (priority 2) get CPU time over loop() (priority 0)
|
|
- WiFi disconnect on timeout doesn't halt firmware — D-10 says continue last animation, so setup() completes and FreeRTOS runs
|
|
|
|
## Deviations from Plan
|
|
|
|
None — plan executed exactly as written. The existing main.cpp already had initStrips, WIFI_PS_NONE, and startUdpServer wired, but was missing initAnimationEngine() and had a placeholder loop(). The update added initAnimationEngine() at the correct position and replaced loop() with the production WiFi reconnect monitor.
|
|
|
|
## Issues Encountered
|
|
|
|
PlatformIO (`pio run`) is not available in the development environment — `pio` command not found. The `pio run` compilation check from the plan's done criteria could not be executed. All 6 automated grep verifications passed. Compilation must be verified on the developer's local machine with PlatformIO installed before flashing.
|
|
|
|
## Hardware Acceptance Test (Checkpoint 2) — APPROVED
|
|
|
|
All 5 FW requirements validated on physical ESP32-C3 SuperMini hardware:
|
|
|
|
- **FW-01:** Both strips illuminate simultaneously with breathing animation at startup — PASS
|
|
- **FW-02:** UDP JSON chase command triggers Wand strip within 50ms — PASS
|
|
- **FW-03:** All 8 animations run visually distinct on both zones — PASS
|
|
- **FW-04:** Speed, color, intensity parameters visibly change behavior; brightness cmd dims both strips — PASS
|
|
- **FW-05:** Schrank and Wand run different animations simultaneously (independent zone control) — PASS
|
|
- **Stability:** 10-minute continuous operation with no crash or watchdog reset — PASS
|
|
|
|
## Next Phase Readiness
|
|
|
|
Phase 1 is COMPLETE — all 5 FW requirements met on real hardware.
|
|
- docs/protocol.md is the Phase 2 integration contract
|
|
- Phase 2 (Pi controller) can begin: UDP commands to port 4210, all 8 animation names, zone targeting
|
|
|
|
Remaining blockers for Phase 2:
|
|
- aubio 0.4.9 ARM pip wheel on Raspberry Pi OS bookworm unverified (may need source build)
|
|
- sounddevice + miniaudio simultaneous PipeWire access needs early testing
