How does a graphic display lcd work?

[Mixboy]

Hi,

I bought a graphic lcd (Powertip PG320240c) and I'm searching a document
that explains how the display works; in fact the lcd hasn't a controller and
I want to implent it with a DSP. Now the display has these inputs:
-FLM
-M
-CL1
-CL2
-D-OFF
-DB0-DB3

How can I control the lcd?

Thanks,

Mauro

Aannndd the very first result that pops up when you enter 'PG320240c'
into google is... a datasheet

.... which has pinouts and dimensions but little else.

I can point you to where I explained this before in case you're still
having trouble. Don't know if there's a better way of directing you
there (Apologies for being a bit of a newb) but here's the link to
another discussion...

Otherwise, search for PolyVinalDistillate here - you'll find it
Good luck. Nick.

Hmm... I attempted to post this morning, but apparently I failed
miserably! I've posted before to explain the functions of the pins on
a GRX LCD panel (at least the functions I'm used to on my mono
panels!)

The link to that thread is here:

You're looking at the 4th posting.

If you want me to help further, I'll check this out from time to
time

I've read the thread and I don't understand how to use the M input. I've
looked the datasheets of common/segment driver (LC79401 and LC79430); it
calls M "LCD drive output alternation signal" but doesn't explain how to
use.

Thanks!
