dc_generator – Provide a direct current (DC) input
==================================================

Description
+++++++++++

The ``dc_generator`` provides a constant DC input to the connected
node. The unit of the current is pA.

The ``dc_generator`` is rather inefficient, since it needs to send the
same current information on each time step. If you only need a
constant bias current into a neuron, you could instead directly set
the property ``I_e``, which is available in many neuron models.

Set parameters from a stimulation backend
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The parameters in this stimulation device can be updated with input
coming from a stimulation backend. The data structure used for the
update holds one value for each of the parameters mentioned above.
The indexing is as follows:

 0. amplitude
