How to interface PIC to Optrex 81852

[misterPIC]

Hello to everybody, i'm new in that forum !

i want to drive optrex 81852 with pic 18F but i'm not expert to interface and write
routines for graphic lcd, because I have ever used standard 20x4 LCD.
If someone have already done a similar project,
i would be very thankful with him if he could help me to do schematich and basic routine.

Have a nice day !

Do you have a datasheet that came with this LCD?

Google doesn't seem to like <optrex 81852>.

Have you looked at the examples I posted for graphic LCDs? Maybe one example might give you insight on how to use the commands if you ever find the datasheet.

sorry but it's OPTREX 51852... in attachment the datasheet.

thanks in advance !

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:

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):

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.
