This software is not associated with PI. Use it at your own risk.
This python module provides access to some basic functionality for PI nano Piezo Stage Controllers. PI also distributes a bindings for their c++ library, but this python module uses the simple Serial Interface most controllers provide, which is more straightforward to use (IMHO).
If you are not 100% sure what you are doing, stick with the software supplied by PI.
At the moment work is only done for the E-545 Controller, because that's the System that I use.
After installing test if it's working by:
import PIStage
stage = PIStage.E545()
print stage.pos()
