Startup cubes on LCD display

[CleanMachine1]

Whenever I give power to my Pi and start, there are squares on the LCD display i am using.

I am also using your go-hd44780

The little squares I think are a result of the CGRAM (I am not completely sure) and I cannot clear them using the built in command provided, and clear appears to do nothing for it.

When I run the binary the first time, it gives logs that it is writing but nothing is shown other than the squares.

My fix is to run the program again and it seems to just clear it then. I am running the same binary.

This happens with even the example code you have provided so I don't think it just code.

Another to note is that https://github.com/d2r2/go-hd44780/blob/74cc28c83a3e864bb5220bba2b0292b1fb29ae67/lcd.go#L225
running this changes the squares to squares with Z in them.

but again, the fix is just to run it again.

Hope you or someone else can help.
