+# WLED 48x32 Modular LED Matrix & DDP Control Daemon
+
+![WLED 48x32 Matrix Demo](demo.jpg)
+
+A high-density 1,536-pixel (48x32) modular LED matrix built across 6 panels in a 3x2 landscape layout. Features custom 3D-printed prismatic diffuser lenses and a thread-safe Python HTTP daemon streaming real-time DDP (Distributed Display Protocol) frame buffers to WLED.
+
+3D CAD files, OpenSCAD scripts, and assembly specs are published on Thingiverse:

+
+## Hardware Architecture
+
+- **Resolution:** 48 × 32 pixels (1,536 WS2812B LEDs)
+- **Panel Grid:** 6 modular tiles arranged in a 3×2 landscape grid (16×16 pixels per tile)
+- **Pitch:** 10mm center-to-center
+- **Diffuser System:** Modular 0.4mm transparent PLA sandwich film with integrated 1.5mm square pegs topped with 0.8mm micro-pyramid prismatic refractors to eliminate light bleed and LED hotspots.
+- **Protocol:** DDP over UDP (Port 4048)
+
+---
+
+## Software & Daemon Features
+
+- **Multithreaded Engine:** Non-blocking Python daemon handling HTTP requests and real-time animation loops concurrently.
+- **Active DDP Keep-Alive:** Streams dynamic background frames during scroll sweep pauses to prevent WLED timeout drops.
+- **Display Modes:**
+  - **Scroll Text:** Variable scroll speed, adjustable sweep pauses, and custom text payloads.
+  - **Digital Clock:** Toggleable date, seconds, and blinking colon. Automatically restricts font selection to monospaced typefaces when active to eliminate horizontal layout jitter.
+  - **Analog Clock:** Procedural analog clock face rendering.
+- **Dual-Layer FX Pipeline:**
+  - Independent foreground (text/clock) and background canvas effect engines.
+  - Supported effects: `solid`, `rainbow`, `gradient-h` (horizontal), `gradient-v` (vertical), and `pulse`.
+- **Interactive Web Control Panel:**
+  - Integrated live WYSIWYG preview box with marquee scrolling animations.
+  - Native HTML5 color wheel selectors.
+  - Real-time cURL command generator for API automation.
+  - Automatic system TTF font detection and web preview font-loader.

+
+## Quickstart
+
+### 1. Run as Daemon
+Start the HTTP controller on your host (e.g., Aurelia or hypervisor guest):
+```bash
+python3 matrix_billboard.py --daemon --listen-ip 0.0.0.0 --listen-port 8080 --ip 192.168.195.216
+
+### 2. restfulAPI example
+```bash
+curl -X POST "http://localhost:8080/" \
+     -H "Content-Type: application/json" \
+     -d '{
+       "mode": "scroll",
+       "text": "WOMAN CAVE",
+       "effect": "gradient-h",
+       "color": "#ff00ff",
+       "color2": "#00ffff",
+       "bg_effect": "solid",
+       "bg_color": "#000000",
+       "speed": 0.04,
+       "sweep_pause": 2.0,
+       "brightness": 255
+     }'
