I had a brief look at this today.  While I cannot present a full solution, I 
think I made some progress.

The first thing is to get the c-python modules in the 
arduino-functions/Digital-I-O to include the right subdirectories from the 
Runtime.  The following in setup.py seems to work as a first approximation:

from os import path


arduelli   = path.join(runtime, 'cores/arduelli')
system_inc = path.join(runtime, 'system/stm32/inc')
cmsis      = path.join(runtime, 'system/stm32/CMSIS/Include')
variant    = path.join(runtime, 'variants/ellduino')

include_dirs=[arduelli, system_inc, cmsis, variant]

setup(name='digitalRead', version='1.0',

The key there is the include_dirs in creating the Extension. See 


for more information. 

With that you can include <wiring_digital.h> in digitalRead.c, but note that it 
must be included *before* including <Python.h>.  That then allows you to call 
the actual Runtime functions, and it compiles.  Python also tries to load the 
resulting shared library, but that fails.

The next step would then be to actually add the emulator functions to the 
python runtime.  That I don't know yet how to do exactly, but I imagine that it 
would be best to compile the emulator into a shared library, through adding a 
new make target in Runtime/stm32/make, and then including the shared library 
into the (DY)LD_LIBRARY_PATH.  That might suffice.
