ks108 datasheet

HI,

I have a graphical lcd but I cant find its datasheet
it is made in china, So all the ICs at the back of this lcd have no Number
there is only one Number written at it: QY-12864BG
is this its serial No or this Number just tells us the resolution is 128*64 pixel????

there are also the pin description which is:
1.. VSS
2.. VDD
3..V0
4..RS
5..R/W
6..E
7:14..d0:d7
15..CS1
16..CS2
17..RST
18..VOUT
19..led+
20..led-

could you tell me what is the function of this pins??
and how to program this lcd using AVR or 8051??

thank you any way....

I would assume a standard 128x64 monochrome display...so...pick a similar model (o;

what is graphical lcd

You must find out the Controller chip of your Graphical lcd . Regular GLcds are based on KS108 contorller or HDM64GS12 or ... .
The datasheet of this controller chips explaines how to communicate with lcd .

i know PG12864 is a TOOSHIBA T6963 GLCD but i think yours is a ks108 (SAMSUNG)
then look at ks108 datasheet.and tell me the ver you use
thanks
 
glcd 128*64 vout

I have no idea about my glcd based controller, the behind ICs have no numbers ( you know these circular ICs which have no pins )

but I think the datasheet which Mr.davorin have posted is so similsr to my glcd

But I still need any example code to run my glcd with AVR or 8051 microcontroller

thank you....

Do you program with asm or with compiler
 
datasheet glcd

it depends on the controller you choose Medtronic..
if 8051 I prefer assembly
but if AVR i prefer C language
but any way, I just want to know the basics
like how to send acommand or a data??
how to know the lcd is busy or not??
etc..
 

purpose of led+ and led- pins in graphical lcd

Look at that

i hope it will help
Thanks
 
lcd ks108

I still cant run this glcd
I need any simple C program or 8051 assembly program, please
just any simple program...............
thanx

hi ......

i want to interface the glcd with AT89C51 microcontroller........tell me how??

Aso send me the programming (in C-KEIL) to drive it........

Thanks
 

8051 microcontroller asm programming graphic lcd

Hi,

As far as my experience(18 years) goes. There are mainly 2 types of GLCD.
The software is the same for all of them, but the connectors are different. I am posting a datasheet for the LCD having the connector you mentioned.

The low level routine is the same as that of 16x2 LCD. But the initialization and control addresses are different.
