Post subject:  need wiring help with 2 lcd's
i have in my pososition 2 lcd's one came out of an old xerox fax machine and has the markings..

DATA VISION
PHICO D-0
9812 94V-0
P124-1
this model has 14 pins/wire coming out of it not 16 like the other models i think the extra 2 wires that i have found on other models are for the lcd backlight

i think that P124-1 is the model number and i understand that PHICO is the board manufacture not the lcd manufacture...

the other lcd is out of a handheld computer PCL-486 (just google it) anyways it is a SII (Seiko) lcd that displays 192x128 pixels and has the markings...

G191C21R0A0

I found a little bit of data on this one but the thing is that as i was typing the model number of this lcd in to the forum post box i noticed that if i pull the film/ribbon cable that covers the back of the board up a little more i noticed that the pinout is already stated (screen printed on the board) but any info on this board would still be helpful.....

i would like to make it so both can be hooked up to parallel port and i will convert them to usb.. but getting them to work is my main goal now!

ps hope that is enough data.... will post pictures soon

here is a link the the datasheet on the P124-1 http://www.dema.net/pdf/dain/DV-20200-S1FBLY.PDF

Sigh....

again i found what i was looking for before anyone else could help but i will post the stuff i found because it is not easy to find...

the P124-1 is also called the DV-20200 and it is a HD44780-compatible lcd

and the pinout/ diagram to parallel is here, http://www.allspectrum.com/LCD-displays ... d44780.gif

that is the diagram for the 20208 but im fairly certian it is the same the only difrence that i see is that the 20208 has 20 pins and the 20200 has 14 but pins 15-20 are not even needed because pin 15 is that same as pin 1 and 16-17 are not used, pin 19-20 are the backlight, but the 20200 has no backlight :(

so it should work ill test it out and tell you how it goes
