Interfacing with external code¶
Some neural simulations benefit from a direct connections to external libraries, e.g. to support real-time input from a sensor (but note that Brian currently does not offer facilities to assure real-time processing) or to perform complex calculations during a simulation run.
If the external library is written in Python (or is a library with Python bindings), then the connection can be made either using the mechanism for User-provided functions, or using a network operation.
In case of C/C++ libraries, only the User-provided functions mechanism can be
used. On the other hand, such simulations can use the same user-provided C++
code to run with the
Standalone code generation mode. In addition to that code, one generally needs to
include additional header files and use compiler/linker options to interface
with the external code. For this, several preferences can be used that will be
taken into account for
cython and the
These preferences are mostly equivalent to the respective keyword arguments for
distutils.core.Extension class, see the documentation of the
cpp_prefs module for more details.
