Hi, as i can see in your readme you have this table

R-PI Model B v2 GPIO
LCD GPIO p1 p2 GPIO LCD
      3v--* o--5v
      02--o o--5v
      03--o o--GND
DC----04--o o--14---RD
     GND--o o--15---WR
RESET-17--o o--18---DB2
CS----27--o o--GND
      22--o o--23---DB3
      3v--o o--24---DB4
IM0---10--o o--GND
DB0---09--o o--25---DB5
DB1---11--o o--08---DB6
     GND--o o--07---DB7
        p25 p26

but on the images i can see, that you are using DB8-DB15 (as advised in the TFT datasheet) Is this correct?

Yes it is. It threw me for a loop to but it works! see (http://www.newhavendisplay.com/specs/NHD-2.4-240320SF-CTXI-T1.pdf) page 4.

Hope the driver works for you.

fixed readme.

Whoops! I think I misread your question. The answer is yes and no. DB0 is bit 0 of the data out and so on(DB7 is bit 7) DB0 on the pi connects to DB8 on the lcd and so on(DB7 on the pi connects to DB15 on the lcd)

I fixed the readme so DB7 on the pi connects to DB7 on the lcd .....
