@AleksandarPetrov this is the log when I try to run the acquisition node on the pi

I googled the error "NULL pointer access" and it seems to have something to do with ctypes.

@surirohit, you are right, this should come from the AT3 bindings. So, this happens only on the RPi? In that case, it could be that you are building the AT3 library for x86 architecture instead of arm?
