PixelStream Example

This example demonstrates how to consume the udp/raw cluster event and drive a NeoPixel strip or matrix directly from streamed RGB data. Frames are provided as hex encoded byte triplets (RRGGBB per pixel).

Features

Subscribes to udp/raw via NodeContext::on.
Converts incoming frames into pixel colors for strips or matrices.
Supports serpentine (zig-zag) matrix wiring.

Payload Format

Each packet is expected to be RAW: followed by pixelCount * 3 * 2 hexadecimal characters. For example, for 8 pixels:

RAW:FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000FF0000

Usage

Strip Mode

Upload the example with PIXEL_MATRIX_WIDTH set to 0 (default). Send frames containing PIXEL_COUNT * 3 bytes as hex.

Matrix Mode

Set PIXEL_MATRIX_WIDTH to the number of columns. The controller remaps even/odd rows to support serpentine wiring.

Configuration

Adjust PIXEL_PIN, PIXEL_COUNT, PIXEL_BRIGHTNESS, PIXEL_MATRIX_WIDTH, PIXEL_MATRIX_SERPENTINE, and PIXEL_TYPE through build defines or editing main.cpp.
