# 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.

## 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
     }'
