I have one 18 pin LCD with this information: 1Qcu099-FLYG-GBW So i don't know what type of the LCD is this and have not find any datasheet form google, So It's picture is here:

If have more information for It's model in Proteus and any driver library for AVR micro's or any datasheet, will be very useful for us.

Edited:

Dose it datasheet is here: wh2004l

if yes, so any AVR library for running it's (wh2004l) with ST7066 Controller IC ?

Thanks a lot.

  • \$\begingroup\$ @LeonHeller - these kind of things are typically similar enough that if one already has the part in hand and it isn't a professional (time and materials both funded) project it can be worth giving it a try based on the data of something similar. Even then, for a one-off need, overnight shipping means the earliest something works is tomorrow, while the part on hand could well end up working today. \$\endgroup\$

The datasheet indicates that this display -- like most small LCD character displays -- implements an interface compatible with the Hitachi HD44780 controller. There are two extra pins on this part (17 and 18), but they can both be safely left disconnected.

This interface is implemented by the Arduino LiquidCrystal library.

Note that RoHS is not a brand name -- it's an inspection mark, indicating that the board (probably) meets the European Restriction of Hazardous Substances directive by not containing any lead, mercury, cadmium, or certain other toxins.
