Module udp_client 

Module implementing high-speed UDP reception for DMX universe streams.

UDP Client / Listener Module

This module handles high-speed, un-acknowledged UDP network reception. It specifically listens for incoming Art-Net DMX protocol packets (OpOutput / OpDmx) on the default port (6454), extracts DMX channel values for target universes, and dispatches universe data frames to the UI for live rendering.

Constants

ARTNET_HEADER 🔒

Art-Net protocol magic header string bytes (“Art-Net\0”).

ARTNET_PORT 🔒

Default UDP port defined by the Art-Net protocol specification.

MAX_CHANNEL

Maximum number of DMX channels per universe according to DMX512 standard.

Functions

handle_generic_packet 🔒

Fallback handler for non-Art-Net UDP datagrams received on the socket.

is_artnet_packet 🔒

Helper function to check if a received byte slice begins with the standard Art-Net header.

start_udp_listener

Binds a UDP socket and spawns a background thread to listen for incoming Art-Net DMX packets.
