    Except for the pinout, that datasheet is almost as useless as a __________ (insert comment here, I use 'dry fart'). No command and control explanations at all...
    But, because of the controller number and the pinout, it looks like it MAY be your standard-run-of-the-mill 128x64 LCD. There's a few examples here on these forums.

    Check this:
    http://www.optrex.com/SiteImages/Par...AN20080104.pdf

    Page 11, figure 7, I suggest the left schematic, unless you want to use the right schematic and deal with an external power supply.

    Page 13, there's a nice wiring schematic.


    And then this code for 51553 (similar, might work):
    http://www.picbasic.co.uk/forum/showthread.php?t=3037

    The 51553 uses a SED1565 controller and the 51852 uses a NJU6676 controller, but they are in the same family of Optrex graphic LCDs.

    Good luck!


    EDIT: It's important to know exactly which model of 51582 you have, not all of them have built-in power supply.
    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
