LCD outputting gibberish

[megaranger]

I have wired up my display from adafruit as per http://learn.adafruit.com/drive-a-16x2- ... -pi/wiring . I am using the 16x2 LCD and the included adafruit python library . The code compiles properly although the display only outputs gibberish. Do any of you have any help with this?

Hi and welcome to the forum.
I don't think this will sort out your problem, but for one thing, it doesn't look like the used data bits DB0 to DB3 are tied low, as thy should be.

Sorry, but what do you mean by having DB0 to DB3 "tied low"? I checked the documentation and it said I shouldn't hook up those ports.

It varies from LCD to LCD, but those unused data lines need to be connected to GND.
Also adafruits documentation does not take into account the v2 Pi. Do you have a v2 Pi?
If so, the program will need reference to GPIO -21 changing to GPIO-27.
