I'm approaching to IoPi by using tutorial1.py.
When i run command python tutorial1.py, this error is raised:
self._bus.write_byte_data(self.address, self.IOCON, self.config)
AttributeError: 'NoneType' object has no attribute 'write_byte_data'
I didn't edit the library file, i've only run this command.
I use python 2.
Can you help me?
