One problem is that you won't be able to use the display with the wires as
you have indicated them. You MUST have DB4-DB7 to access the display at all,
and you need DB0-DB3 as well if you want to use 8-bit mode rather than 4-bit
mode. I'd suggest you pinout your display as:
RB2-3: Use for whatever you want
and then use the display in 4-bit mode.
