unfortunately I have some troubles while starting FruityDisplay. As I told you in other posts I have allready played arround with the Adafruit PiPlate and it works well on my Pi where FruityWifi is running. But when I tried to start your code the first issue was, that ther was no screen library. Thanks to goolge I downloaded it. Error Message about Screen.py was gone.
Unfortunately this was not all the of my troubles. While starting FruityDisplay I get this output. And I don't know how I can fix it. Certainly it's just a trifle but I can't fix it.
have found it on my system. I'm actualy not at home so I can't give you the path. But i just made a "locate screen.py" and than made a copy to the FruityDisplay folder. That worked for me. When this did not help ou I can loo at my system for the path when I am back from work.
