class spynnaker.pyNN.connections.ethernet_control_connection.EthernetControlConnection(translator, local_host=None, local_port=None)

Bases: spinnman.connections.udp_packet_connections.eieio_connection.EIEIOConnection

A connection that can translate Ethernet control messages received from a Population

Parameters:

• translator – The translator of multicast to control commands
• local_host – The optional host to listen on
• local_port – The optional port to listen on

spynnaker.pyNN.connections.spynnaker_live_spikes_connection module

class spynnaker.pyNN.connections.spynnaker_live_spikes_connection.SpynnakerLiveSpikesConnection(receive_labels=None, send_labels=None, local_host=None, local_port=19999, live_packet_gather_label='LiveSpikeReceiver')

Bases: spinn_front_end_common.utilities.connections.live_event_connection.LiveEventConnection

A connection for receiving and sending live spikes from and to SpiNNaker

Parameters:

• receive_labels (iterable of str) – Labels of population from which live spikes will be received.
• send_labels (iterable of str) – Labels of population to which live spikes will be sent
• local_host (str) – Optional specification of the local hostname or IP address of the interface to listen on
• local_port (int) – Optional specification of the local port to listen on. Must match the port that the toolchain will send the notification on (19999 by default)

send_spike(label, neuron_id, send_full_keys=False)

Send a spike from a single neuron

Parameters:

• label (str) – The label of the population from which the spike will originate
• neuron_id (int) – The ID of the neuron sending a spike
• send_full_keys (bool) – Determines whether to send full 32-bit keys, getting the key for each neuron from the database, or whether to send 16-bit neuron IDs directly

send_spikes(label, neuron_ids, send_full_keys=False)

Send a number of spikes

Parameters:

• label (str) – The label of the population from which the spikes will originate
• neuron_ids (list(int)) – array-like of neuron IDs sending spikes
• send_full_keys (bool) – Determines whether to send full 32-bit keys, getting the key for each neuron from the database, or whether to send 16-bit neuron IDs directly
