Hi,

A very short review of the datasheet indicates that the GLCD you posted uses the NUJ6450 LCD driver chip. A further very short Google search indicates that the NUJ6450 and the SED1520 LCD drivers are compatible. And finally, a very short forum search found a working SED1520 driver.

Was there anything else Wink

?

Use forum search, put in SED1520 and you will find the driver.

OK, as was said earlier by ezflyer, a short search with Google and the second hit gives this:

Thanks for your help !
By the way, I said before in a comment that i tried a driver and didn't work
and unfortunately that one you gave me is what i was talking about.
Is there any driver compatible with graphics.c ?

A check of the part number on the display confirms it is a standard SED1520
driver. Forget about graphics.c and use the last driver I pointed you to. It is
a known good driver. You likely have connection issues.

That display looks unused. Are you using real hardware or Proteus?

I usually start with simulation on Proteus then go to real hardware.
Why there is a CLK pin in that driver, I checked it on my LCD, doesn't exist !

If you are using Proteus I am unwilling to assist you further unless you
switch to real hardware. I don't do Proteus, too may bugs and
problems...sorry.

Maybe the Proteus forum can assist. I feel sure there are a number of
people over there that have used a GLCD and know about any bugs you
might encounter..

BTW, if your display doesn't need the clock then don't connect it.
