LCD Random Spaces W/Raspberry Pi

Post by Mikezlav »

I was testing out my 16x2 LCD screen with the adafruit charLCD examples, and there are random blank spots and you can't see the leters that are supposed to be in those spots. When I turn on the pi, all the squares are lit up.
This is what it looks like

It looks like the display has power, and some input stored in its character memory.

Could you post a photo showing your whole setup please, with the connections to the RasPi and anything else that might be connected?
