    hi,

      it is a very simple task.

      by refering the datasheet of jhd12864 you can get the initial values you need to send to the lcd controller.

      if the code is working in proteus, you might have made some mistakes in the hardware connections.

      try it with another new GLCD, and do not make any mistakes while connecting.

    Hi,

    Could you please post the schematic or the location in this site from you copied the code, so that we can have clues for the possible mistakes.

    pratiik, Most probababaly you have done some hardware mistake. Bcoz i checked code and used code from here. You can refer datasheet of graphical LCD and Connect variable resistance at VEE pin.
