- AwtrixFont (BSD-3-Clause TomThumb), MQTT, OSC, text overlay - Pixel effects: sparkle, twinkle, strobe, blink, rain - First-boot cfg.json template (behav:1, dpx-tc002 AP, GPIO32 256 LEDs) - Buzzer RTTTL support - Loop rate-limited to 50Hz; UDP open deferred to connected() - platformio_override.ini: ulanzi_tc001 USB env, shared build flags - tools/ltc_osc_bridge: LTC→OSC bridge utility
- Remove custom /api/* routes — stripped dpx_api.h to /dpx status endpoint - Add dpx_mqtt.h: MQTT subscribe via WLED broker (dpx/# topics) - Add dpx_overlay.h: text overlay + pixel effects (sparkle/strobe/rain/twinkle/blink) - Add dpx_firstboot.h: write /cfg.json on first boot (dpx-tc002 AP, behav=1, 2D 32x8) - Replace 5x7 column-major font with AwtrixFont (BSD-3-Clause TomThumb-derived) - Rewrite dpx_text.h renderer for GFX row-major format; fix baseline (y=0 was off-screen) - Fix REGISTER_USERMOD missing from dpx_matrix.cpp — usermod now actually loads - Fix UDP crash: move dpxOscBegin() to connected() (lwip not ready in setup) - Rate-limit loop() to 50Hz — was hammering UDP socket stack on every tick - Fix root / route shadowing WLED web UI (ESPAsyncWebServer LIFO order) - Print IP to serial on WiFi connect; reprint when monitor opens - Guard DEFAULT_LED_COUNT in const.h to avoid redefinition warning - Refactor firstboot from raw JSON string to ArduinoJson builder - readme: filled in About, Getting Started, First Boot Defaults, Usage, Acknowledgments - platformio_override.ini: OTA env, shared common section, DPX_BTN pins
…e; serial debug; roadmap
- Any app (incl. native Time/Date/WLED) removable from rotation via dpxHiddenApps set
- WLED native app: silent passthrough so WLED effects show full screen
- handleButton() replaces _pollBtn: debounce + short/long press, uses WLED APIs
- Button layout fixed (mid/right were swapped)
- Time/Date use WLED localTime + hour()/minute() — respects useAMPM setting
- NTP enabled in firstboot config; firstboot 2D default serpentine=true
- Serial 's' command dumps IP, AP, WiFi, heap, time, app, MQTT, OSC status
- App mute: dpxMuteApp() + MQTT dpx/mute/<name> + JSON {dpx:{mute:{Name:bool}}}
- Channel mute shown in GET /dpx/apps response
- useAMPM respected: 12h with a/p suffix or 24h based on WLED setting
- ROADMAP.md: Phase 1.5 ctrl UI refactor scoped and queued
…e cleanup - WLED_NTP_ENABLED=true in platformio_override.ini (default was false) - NTP status added to serial 's' debug dump - DNA Spiral (effect 182) set as default startup effect in firstboot - Removed transition=0 from firstboot so power fade works again - Time/Date render: snapshot localTime; leftover fragment removed - Reverted forced ntpEnabled override (not needed with compile flag)
feature/buzzer rtttl
- Register 'dpx Matrix' as WLED effect wled#200 via strip.addEffect() - dpxSetPixel/dpxGetPixel/dpxClear now use SEGMENT APIs (setPixelColorXY) → brightness, transitions, power-fade, and 2D panel mapping all work natively - handleOverlayDraw() removed entirely - dpxActivateEffect(): auto-switch to dpx Matrix when TC/notify/app arrives - 'WLED' rotation slot now switches AWAY to DNA Spiral (passthrough restored) - _dpxEffectId moved to dpx_apps.h so it's visible before first use - firstboot default fx updated to 200 (dpx Matrix)
- WLED slot removed from native app list — dpx Matrix IS the effect, there is nothing underneath to passthrough to - Effect registered with ID 255 (auto-assign) instead of 200, which conflicted with existing built-in effects - Dead WLED passthrough handler removed from dpxRenderCurrentApp - firstboot: def.fx removed (effect ID is dynamic, set via dpxActivateEffect)

WalkthroughThe change establishes the DPX Matrix firmware foundation for WLED, including rendering, apps, overlays, notifications, HTTP/MQTT/OSC control, and persistence. It also adds an LTC-to-OSC bridge with CLI and web GUI modes, plus hardware configuration, project documentation, templates, and release metadata. ChangesDPX Matrix firmware
