        CircuitPython library for the Maxim DS1841 I2C Logarithmic Resistor
        
        
        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-ds1841/>`_. To install for current user:
        
        .. code-block:: shell
        
            pip3 install adafruit-circuitpython-ds1841
        
        To install system-wide (this may be required in some cases):
        
        .. code-block:: shell
        
            sudo pip3 install adafruit-circuitpython-ds1841
        
        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-ds1841
        
        Usage Example
        =============
        
        .. code-block:: python
        
            from time import sleep
            import board
            import busio
            import adafruit_ds1841
            from analogio import AnalogIn
        
            ####### NOTE ################
            # this example will not work with Blinka/rasberry Pi due to the lack of analog pins.
            # Blinka and Raspberry Pi users should run the "ds1841_blinka_simpletest.py" example
        
            # WIRING:
            # 1 Wire connecting  VCC to RH to make a voltage divider using the
            #   internal resistor between RH and RW
            # 2 Wire connecting RW to A0
        
            i2c = busio.I2C(board.SCL, board.SDA)
            ds1841 = adafruit_ds1841.DS1841(i2c)
            wiper_output = AnalogIn(board.A0)
        
            while True:
        
                ds1841.wiper = 127
                print("Wiper set to %d"%ds1841.wiper)
                voltage = wiper_output.value
                voltage *= 3.3
                voltage /= 65535
                print("Wiper voltage: %.2f"%voltage)
                print("")
                sleep(1.0)
        
                ds1841.wiper = 0
                print("Wiper set to %d"%ds1841.wiper)
                voltage = wiper_output.value
                voltage *= 3.3
                voltage /= 65535
                print("Wiper voltage: %.2f"%voltage)
                print("")
                sleep(1.0)
        
                ds1841.wiper = 63
                print("Wiper set to %d"%ds1841.wiper)
                voltage = wiper_output.value
                voltage *= 3.3
                voltage /= 65535
                print("Wiper voltage: %.2f"%voltage)
                print("")
                sleep(1.0)
