Tested working with RPI2?
I have tried to get this working with two different Adafruit "adventures in raspberry pi" kits + RPI2 and am getting a light but no "This is a test". Yelp!
GPIO port numbering for rev 1 boards vs rev 2 in Adafruit_CharLCD.py
I needed to alter the pin number from 27 to 21 for this to work on my rev1 Raspberry PI, it would be nice if there was a revision check added to make this work "by default" regardless of the board revision e.g. as discussed at
