InSpiNNuator - Pretend to be a SpiNNaker board transmitting UDP packets to a host. Packets resemble those produced by io_printf.
import random, struct, socket, time
def generate_packet( data ):
"""Generates a random SpiNNaker UDP Packet with a random
chip x, y and core (taken from some sensible range)."""
# Pick x, y, core
x = random.randint( 0, 4 )
y = random.randint( 0, 4 )
core = random.randint( 0, 17 )

An attempt to build a working NEF example from scratch. Currently only for 1 dimension, but will work on `n` dimensions as soon as possible.

"""Attempt #1 at organizing neuron models
- We specify types of neurons using subclasses of Neuron
- This includes things like LIF vs HH and also Float vs Fixed, Rate vs Spiking
- We build a NeuronPool object which actually has code for running neurons
- We keep a list of known Neuron types around so if we're asked for just
a Rate neuron, we can pick the first on on the list that matches
Modified from @tcstewar's original to remove a fixed point divide.
