        Dependencies
        =============
        This driver depends on:
        
        * `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
        * `Bus Device <https://github.com/adafruit/Adafruit_CircuitPython_BusDevice>`_
        * `Register <https://github.com/adafruit/Adafruit_CircuitPython_Register>`_
        
        Please ensure all dependencies are available on the CircuitPython filesystem.
        This is easily achieved by downloading
        `the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_.
        
        Installing from PyPI
        =====================
        
        
        On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
        PyPI <https://pypi.org/project/adafruit-circuitpython-pcf8591/>`_. To install for current user:
        
        .. code-block:: shell
        
            pip3 install adafruit-circuitpython-pcf8591
        
        To install system-wide (this may be required in some cases):
        
        .. code-block:: shell
        
            sudo pip3 install adafruit-circuitpython-pcf8591
        
        To install in a virtual environment in your current project:
        
        .. code-block:: shell
        
            mkdir project-name && cd project-name
            python3 -m venv .env
            source .env/bin/activate
            pip3 install adafruit-circuitpython-pcf8591
        
        Usage Example
        =============
        
        .. code-block:: python3
        
            import time
            import board
        
            import adafruit_pcf8591.pcf8591 as PCF
            from adafruit_pcf8591.analog_in import AnalogIn
            from adafruit_pcf8591.analog_out import AnalogOut
        
            ############# AnalogOut & AnalogIn Example ##########################
            #
            # This example shows how to use the included AnalogIn and AnalogOut
            # classes to set the internal DAC to output a voltage and then measure
            # it with the first ADC channel.
            #
            # Wiring:
            # Connect the DAC output to the first ADC channel, in addition to the
            # normal power and I2C connections
            #
            #####################################################################
            i2c = board.I2C()
            pcf = PCF.PCF8591(i2c)
        
            pcf_in_0 = AnalogIn(pcf, PCF.A0)
            pcf_out = AnalogOut(pcf, PCF.OUT)
        
            while True:
        
                print("Setting out to ", 65535)
                pcf_out.value = 65535
                raw_value = pcf_in_0.value
                scaled_value = (raw_value / 65535) * pcf_in_0.reference_voltage
        
                print("Pin 0: %0.2fV" % (scaled_value))
                print("")
                time.sleep(1)
