'[OT] identifying a LCD Panel'
Hello again PICsters. A friend has given to me an LCD panel with no info or
specs, and I am triying to identify it in order to make something usable
The only info I can see is, in different places:
Is one row, and th ucontroller in the back is a 8M3- HD44780A00, with 14
pins and a C.A. connexion, so i think is backligthed..
absolute no info in a Inet search (altavista, etc.)
Somebody knows something about it?
Try searching for "industry standard alphanumeric display controller". :)
You have stumbled on the standard character mode LCD display. '44780' is
the Hitachi controller that is very common for character LCDs. Also, the
14 pin interface is a good sign that it is at least a 44780 copy.
Seriously, search for 44780. There is LOADs of info, pic code, an
application note on http://www.microchip.com etc. Needless to say, I never got
mine working... :(

Take a peek
at http://www.eio.com/cgi-bin/byteserver.pl/m16410a.pdf . I think this
part your have. Fortunately, the pinouts of the LCD modules using the
controller are (as far as I can tell) identical.
There is a lot of code available to show how to use the display. One sample
a DDS synthesizer project) is at
http://waterw.com/~njqrp/mbrproj/dds_vfo4.txt . There
is also somewhere, a program that will write a test pattern to the LCD,
with single and double row LCDs or different lengths. I can't find it right
now or I would
include it. I'll follow up if I can find the code.
BTW, this was all found through AltaVista ;-)
