Description: PCF8575
        =======
        
        Python library for the PCF8575 I2C IO expander. It abstracts the 16 bit IO port as a Python list, and allows the read/writing of individual pins or the whole port at once.
        This is a modified version of the [PCF8574](https://github.com/flyte/pcf8574) library to support the extra 8 ports.
        
        ## Installation
        
        The library depends on the `smbus-cffi` package. You may need to `apt-get install libffi-dev` if you're on a debian based system. Otherwise, simply:
        
        ```
        pip install pcf8575
        ```
        
        ## Usage
        
        ```python
        In [1]: from pcf8575 import PCF8575
        
        In [2]: i2c_port_num = 1
        
        In [3]: pcf_address = 0x20
        
        In [4]: pcf = PCF8575(i2c_port_num, pcf_address)
        
        In [5]: pcf.port
        Out[5]: [True, True, True, True, True, True, True, True]
        
        In [6]: pcf.port[0] = False
        
        In [7]: pcf.port
        Out[7]: [False, True, True, True, True, True, True, True]
        
        In [8]: pcf.port = [True, False, True, False, True, False, True, False]
        
        In [9]: pcf.port
        Out[9]: [True, False, True, False, True, False, True, False]
        
        In [10]: pcf.port[7]
        Out[10]: False
        
        In [11]: pcf.port[6]
        Out[11]: True
        ```
