I have read about the great work on interfacing the Nokia Color lcd's. I havn't the manufactor that was recomended to proceed with my experiments on this lcd.

I'm still trying to get a lcd to work with a PIC micro and the SonyEricsson T68 display is one that a have a couple of and it has nice pads to solder on.

I know that I have seen the Pinout somewhere but can't find it right now. If you have it, please post it for me.
All information on manufactors and communication specifications you might have would be great!

Best regards

Mippen

Thanks!

Great info.

pin1 Vlogic ( 2.8 - 3.2 V)
pin2 Gnd
pin3 _Reset ( active and for iic interface)
pin4 Sdata
pin5 Sclck
pin6 +Led1
pin7 Gnd (leds)
pin8 +Led2

I2c address:0x72 Only write mode

Resolution: 101x80 RGB



Is there a "standard" on what commands that is used on I2C?
I guess that one needs some kind of communication specification to be able to get any information on the LCD?

I found this information for T68 LCD.

IC Controller: UPD161401
Liquid Crystal Display (LCD)Controller/Driver IC
Vendor: NEC
Number of Characters 101 x 80 pixels (256 colors)
Logic Voltage (V)/ Drive Voltage (V) 1.8 to 3.6/ 18

I not found data-sheet for NEC UDP161401

@lcdmania:

where have you found this information? (i'm searching for voltage info and pinout for ericsson r520)

@mippen:



yes, but the i2c-protocl only standardises the way of how commands and data is exchanged between i2c-devices.

for the commands you need a datasheet. without you're lost (or you may try sniffing the i2c-communication. there're some programs and tutorials floating around the net).
but if you'll find the datasheet for 'nec udp...' it's very ease to drive an i2c-display

edit: incorrect end-tag, typo

All I have found on the NEC LCD Driver uPD161401 is the following:

Full-dot driver
101x80 dots output
1.8 to 3.6 Logic voltage, 18v drive voltage(???)

Seems that there is some other models in the same family, maybe the same communication protocol on these? If one could find it?

uDP161401 (101x80 dots)
uDP16686 (128x128 dots)
uDP16687 (128x128 dots)

@mippen

i have the opposite problem: i know the controller, but i don't know pinouts and voltages :-(

maybe you know something about this (or you have found something about) for ericsson r520.

@mippen

good news for you, i've found the document you're searching for, but i don't want to direct-link it (dunno if nec would be happy about that). so here's a 'how to':

go there:
http://www.necel.com/en/search/index.html

at 'Document Search' field 'Product Name' enter:

*161401

and press enter.

(the * at the beginning is necessary!)

the document you need will be loaded by acroread ;-)


and also bad news:
are you sure that this is the right controller?
udp161401 has two parallel, one serial, but no i2c transfer mode. either berty's pinout is wrong, or t68 doesn't use this controller or i overlooked something

i2c is serial mode.

@lcdmania




i2c is a serial protocol. but if you would have read the datasheet you would have seen that the controller does not support i2c but a proprietary serial communication protocol (look at figure 5-1) - some protocol similar to those protocols used by certain nokia-displays (and certain other ones) using serial communication.
i programmed a library with support for such displays: http://serdisplib.sourceforge.net (there's also support for ericsson t2x displays: these are i2c-displays ..)

so there's either a i2c-chip BEFORE this nec-controller or the search has to continue ;-)

I spend like 2 weeks getting info in the T68i's , and im 99% sure there are 3 versions of that disp.

Version 1: name=S-4595;type=01;address=72

Version 2: name=HD66760;type=02;address=74

Version 3: name=S-43200A;type=03;.address=70

The ones i have ansvers on I2C addr 70 , so i Suppose its a S43200A , and i can find NOTHING on that one or the S-4695 (well i got one hit on a S-4595b i think)

I have the Hitachi manual , but no Hitachi LCD


Im 95% sure the S-controllers are Seiko OEM controllers ......

Here are some hits ...

The 2 first made by my selve
http://www.eio.com/public/lcd/1309.html
http://www.eio.com/public/lcd/1313.html

Another one
http://www.esato.com/archive/t.php/t-14585


My assumptions are based on the firmware dump of the T68i and the section that contains this...

I'm sorry the paste is a bit of a mess , but its a hex dump with the Ascii part at the end of each line.

Hi.

Anyone here that knows anything about the LCD used on Nokias 3300&6800 models?
Looking for Pinouts, controllerinfo and datasheet or just about anything I can find.
TIA

/Jimmy

Hi,

Are there any progress in identify the controller chip of T68. I found this web site http://www.dainau.com/T68LCD.htm

Phtos shown the T68 LCD panel is driven sucessfully but the gug did not release any technical details. He wants to sell the whole package with US89?

There is a "T68 color LCD download program" in the free download section. I guess it is demo codes for PIC. May be somebody familar with PIC can get some useful information and may confirm which controller chip is used.

Best regards,

thx for dump Bingo! its working for me
