Turning off the PiFace Control and Display

Here's how to go about making sure the LCD screen cleans up after itself

I have been playing with the PiFace Control and Displayย and have been absolutely loving it. I will be posting up plenty more about it in the coming weeks.

I have noticed when I am using the Python library PiFaceCAD and do something daft that makes the program exit incorrectly the LCD screen doesn't clean up after itself.

It feels like this would be a drain on battery and just knacker the hardware a bit quicker so I have written a quick Python script that will turn the LCD screen off. You can run this if ever you notice your screen on when it shouldn't be.
