    I meant the LCD timing specs that have differencies. So the end user may have to take into account that.

    Things to adjust include these DEFINEs (from the manual):

    ' Set command delay time in us
    DEFINE LCD_COMMANDUS 1500

    ' Set data delay time in us
    DEFINE LCD_DATAUS 44

    44 maybe on the edge. 50 maybe more safe.
