UDP Receiver

class gpype.backend.sources.udp_receiver.UDPReceiver

Bases: EventSource

UDP network receiver for capturing remote trigger events.

Provides network-based event capture. Listens on specified IP/port for UDP packets containing numeric trigger values. Each trigger outputs the received value, followed immediately by a zero.

DEFAULT_IP = '127.0.0.1'

Default IP address for localhost binding

DEFAULT_PORT = 1000

Default UDP port number for listening

HOLD_TIME_MS = 10

Hold time in milliseconds before sending reset trigger

class Configuration

Bases: Configuration

Configuration class for UDP receiver network parameters.

class Keys

Bases: Keys

Configuration key constants for the UDP receiver.

IP = 'ip'

Configuration key for IP address binding

PORT = 'port'

Configuration key for UDP port number

__init__(ip='127.0.0.1', port=1000, **kwargs)

Initialize UDP receiver.

Parameters:

• ip (str) – IP address to bind socket to. Use “0.0.0.0” for all interfaces or “127.0.0.1” for localhost. Defaults to localhost.

• port (int) – UDP port number to listen on. Defaults to 1000.

• **kwargs – Additional parameters for EventSource base class.

start()

Start UDP receiver and begin listening for messages.

Initializes background UDP listener thread and starts monitoring for incoming trigger messages.

stop()

Stop UDP receiver and cleanup network resources.

Stops background listener thread, closes UDP socket, and waits for clean thread termination.
