4-Bit Interface

I am attempting to implement the 4-bit interface, but have had no success. Any pointers?

I noticed that the unused pins (DB0 - DB3) are high by default. Should i ground these pins or should this not be the case?

Any help would be appreciated.

The pins NEED to be grounded as they are high by default.

I finally got something to print to the display :)
