Hi Ashok,

Can you please tell me if you are initializing the display at all?
Also can you tell me the voltage you are applying to Pin 3 (V0) of the display?

Seeing boxes could mean that the display contrast voltage isn't set to the proper level, or the display isn't initialized and is waiting for the initialization sequence.
