Thanks to Adolf for sending in his project! Check out more info here.
Here the illustration of the shutter controller. Here you see two shutters and on all shutters the same action is performed when up/half/down button is pressed on the piface.
No timing needs to be configured manually since all end positions and travel times are detected using monitoring the current on first action. Only the shutters have to be wired that all go in same direction on same polarity.
The code is super easy and just one little piece of python which covers all. No messing around with hardcoding shutter timings etc.
