Note

You can launch an interactive, editable version of this example without installing any local files using the Binder service (although note that at some times this may be slow or fail to open):

The most simple case how to use standalone mode with several run() calls.

from brian2 import *
set_device('cpp_standalone', build_on_run=False)

tau = 10*ms
I = 1  # input current
eqs = '''
dv/dt = (I-v)/tau : 1
'''
G = NeuronGroup(10, eqs, method='exact')
G.v = 'rand()'
mon = StateMonitor(G, 'v', record=True)
run(20*ms)
I = 0
run(80*ms)
# Actually generate/compile/run the code:
device.build()

plt.plot(mon.t/ms, mon.v.T)
plt.gca().set(xlabel='t (ms)', ylabel='v')
plt.show()
