Fixed bug where legacy configurations without "drv" field defaulted all buses to RMT, causing invalid configurations when RMT channels were full. **Problem:** - Legacy configs from before user-selectable drivers don't have "drv" field in JSON - When loaded, all LD (driver) dropdowns defaulted to RMT (first option) - If config had more buses than RMT channels, configuration was invalid - Example: ESP32-S2 with 6 digital buses → all RMT → 6/4 channels used (invalid) **Solution:** Added `fixLegacyDriverConfig()` function that: 1. Detects legacy configs (all LD fields are unset or all RMT) 2. Intelligently assigns drivers based on hardware limits: - First N buses → RMT (up to maxRMT: ESP32=8, S2/S3=4) - Remaining buses → I2S (up to maxI2S: ESP32/S2/S3=8) 3. Called automatically after config loaded from backend 4. Also called when loading config from JSON file **Implementation:** - Lines 817-872: Added fixLegacyDriverConfig() function - Line 51: Call after backend config loaded - Line 957: Call after JSON file loaded - Line 925: Load drv field from JSON when present - Uses existing isDig(), isD2P() helpers to identify digital buses - Only processes ESP32 variants (is32(), isS2(), isS3()) **Behavior:** - **Legacy config with 6 buses on ESP32-S2:** - Old: All 6 RMT → INVALID (exceeds 4 RMT limit) - New: 4 RMT + 2 I2S → VALID - **Modern config with drv field:** No changes, respects saved values - **New buses:** Already handled by existing addLEDs() logic **Benefits:** - ✅ Legacy configs automatically upgraded on load - ✅ No user intervention required - ✅ Backward compatible with old configurations - ✅ Respects hardware channel limits - ✅ Prevents invalid "all RMT" configurations - ✅ Works for both backend-loaded and file-loaded configs **Testing:** - ✅ Web UI built successfully - ✅ All 16 npm tests passed - ✅ No compilation errors - ✅ Logic only affects legacy configs (all RMT) Co-authored-by: DedeHai <6280424+DedeHai@users.noreply.github.com>
Welcome to WLED! ✨
A fast and feature-rich implementation of an ESP32 and ESP8266 webserver to control NeoPixel (WS2812B, WS2811, SK6812) LEDs or also SPI based chipsets like the WS2801 and APA102!
Originally created by Aircoookie
⚙️ Features
- WS2812FX library with more than 100 special effects
- FastLED noise effects and 50 palettes
- Modern UI with color, effect and segment controls
- Segments to set different effects and colors to user defined parts of the LED string
- Settings page - configuration via the network
- Access Point and station mode - automatic failsafe AP
- Up to 10 LED outputs per instance
- Support for RGBW strips
- Up to 250 user presets to save and load colors/effects easily, supports cycling through them.
- Presets can be used to automatically execute API calls
- Nightlight function (gradually dims down)
- Full OTA software updateability (HTTP + ArduinoOTA), password protectable
- Configurable analog clock (Cronixie, 7-segment and EleksTube IPS clock support via usermods)
- Configurable Auto Brightness limit for safe operation
- Filesystem-based config for easier backup of presets and settings
💡 Supported light control interfaces
- WLED app for Android and iOS
- JSON and HTTP request APIs
- MQTT
- E1.31, Art-Net, DDP and TPM2.net
- diyHue (Wled is supported by diyHue, including Hue Sync Entertainment under udp. Thanks to Gregory Mallios)
- Hyperion
- UDP realtime
- Alexa voice control (including dimming and color)
- Sync to Philips hue lights
- Adalight (PC ambilight via serial) and TPM2
- Sync color of multiple WLED devices (UDP notifier)
- Infrared remotes (24-key RGB, receiver required)
- Simple timers/schedules (time from NTP, timezones/DST supported)
