    hey thnks....i think y there are there are only 10 pins...so i lookd for the working of the chip(HD44780 usually) controlling the lcd ...it turns out that the chip can work in 4bit data mode instead of 8 bit mode.& the read or write pin might be shorted to vcc to make it write only..
    so the pins must be
    1 gnd
    2 vcc
    3 contrast
    4 register select
    5 enable
    6
    7
    8
    9-all data pins
    10-backlight.

    i have done proj using pic16f877a for controlling LCD 16x2,so had to study the whole thing....but the lCD i used was the 16 pin one..

    I know it has been a while but did you ever get this thing to work? I happen to have the very same lcd as you and am hoping to get it going. A reply would be much appreciated :D

    well google the data sheet for the LCD u r using (e.g 16x2 LCD). inorder to get it working u will have to interface it with a microcontroller (i used AT89C51). U have to programme the LCD using any language (i used C++) and then there is the software name keil...in which u run ur code n they give u the .hex file,which u will burn onto ur microcontroller.using a burner...now wen u r done with tht....connect the microcontroller with LCD (see the pin configuration of both LCD and microcontroller)...n there u go...its done :)
    regards
