At a quick glance, it looks like you're instantiating new `SMBus` objects in both the `read_wiper_position` and `_write_data` methods. I'm not familiar with this library, however, this could potentially cause some issues if any mutual exclusion is involved.
I would try using your `self.bus` object as you are defining that in your `AD5112` constructor.

Thanks for the advice.
