So, just to try and keep the wheezy up to date I did an
apt-get dist-upgrade and upgraded a couple of things, among which python.
Now, when I try runing the example
./Adafruit_CharLCD.py I get no output to my mini LCD screen, which before the update all was going great.
I don't get any kind of error besides the same one as before
./Adafruit_CharLCD.py:68: RuntimeWarning: This channel is already in use, continuing anyway. Use GPIO.setwarnings(False) ....
Any ideas what could go wrong, or any way of debugging why doesn't it output nothing?
