I have a QY-1604A LCD display, made in china, text based LCD display. Do any one of you have one? (I'll post more if I get a reply)
 

pinout lcd 4x16

can you say how much character it has in one line
and how many line it has
 

lcd display qy

Maybe it's 4 by 16 (4 lines by 16 character). Is it the same with hitachi models?

I have seen some LCD aside from hitachi, they follow the same protocol some how some of the difference are the pin number and pin layout.

If possible send some pictures.

Judging from the size (16x4) and the pinout, it seems HD44780-compatible. 90% of all text mode LCDs follow this.

http://home.iae.nl/users/pouweha/lcd/lcd.shtml seems like a good resource for controlling this type of LCDs.

Base on the connector pins name, it is 100% HD44780-compatible LCD module. Your LCD library is for that kind of LCD module.

4x20 lcd display c51 program

Hi
all of charachter LCDs are similar to each other, in their read,write and commands.
all of charachter LCDs like 2x16,1x20,4x16,4x20,... have 16 pin's like a lcd that you sent it's picture.
i drived 2x16 lcd later and 4x20 charachter LCD with AVR recently.
maybe their ram address have difference.

lcd display qy-16

I am confirming it's a Hitachi.

This one is by and far the best LCD library for AVR. It is fully customizable. It's from Peter Fleury.

Has anybody got a C program of how to program the LCD rather then assembly?
