I have one LCD that I know is an original because I pulled it out of a nokia phone. It uses the Epson controller and works (and looks), great.

If I put one of my 'copies' into the phone it doesn't work! - Actually one did a while back but the image was horizontally inverted and very dim.

It could be that Nokia keep updating their phones (cost down?), and as a result maybie the required LCD spec keeps changing. Who knows?.

If you look on ebay for these Nokia LCD parts as spares some sellers say ' don't get caught out! get the latest version - older versions may not work' etc. Maybie this is what they are hinting at.???

Anyway I have all of my varities working now, albeit with a little fiddling.

Until the next batch arrives....

Hello everyone,

I am not into technique! but i find this mini LCD a nice product, is there already someone who has a complete working product? :-)

I just want to buy a display that is running and where it is easy to upload my own pictures.

Please tell me if that's a possibility!

Greatings

I have a small spy camera, and want to connect it to a color lcd, If anyone knows of a page/topic with a walkthrough, or info on this type of project please post.

thank you :?:

I have a 6610 LCD, it maybe use EPSON chips, the pin5-VDDI and pin6-VDD connect 3.3V, the backgroud is very light when we run the code, so i cann't seen the character.
I found have several ways can seen the display:
1, I tilted the LCD about 130 degree, we can see the diaplay.
2, I fall the VDDI and VDD voltage from 3.3 to 1.65V, so the display normal.

I think it maybe issues with the contrast and VDDI voltage, but i don't know how to set the contrast for EPSON chips.
I check Nokia 6610 schematics, the pin5-VDDI connect 1.8v and the pin6-VDD conect 2.8V, so i don't know how to set the voltage.

my code is:
void init_lcd(void)
{
//int i;
glcdn_Delay(20000);

/////PORTB&=0b11010111;
/////DDRB|= 0b00101000;

Hi,

Does anyone know which controller the Nokia 3220 phone uses, and the pinouts of the connector?

It has 12 pin connector and the display is 128 x 128 pixels.

Wow...its good display :)

i have one too and now making to conection to PC...I need realy fast uchip.Now using Atmel89c2051 and framerate is about 2-4second per image..

Its connect to LPT port....and runing on 16bit colour (2x256) I make simple program in Visual Basic to controll this...

Hey, is there an easy way to get ASCII characters to display on this LCD with the 9bit serial interface. I've been going through the datasheets and haven't found anything yet. I was thinking about using it for my senior design project but if it's just pixel control then I'll use something else. I had hoped to get my program up and running on it and add some eye candy at the end of the semester if there was time, but I have to be able to display ASCII characters on it.

I guess I should mention...I'm using a PIC18F1320 for the microcontroller.

Although the display is just graphics it's quite easy to display characters with a text function. Theres an example for download for this display (see www.picmodules.com) showing just how to do it. Displays available too!

there is a couple places to get some from.

&

NOTE: the version from display3000 is of a beter quality for whatever reason.

Hello All,

I posted two new questions regarding the Sparkfun Nokia knock-off in "Development," one level in the forum above this one. I figured these questions deserve fresh topics, but I definitely want to make sure I capture the expertise of the readers of this particular thread!

apologies for the x-list/ potentially annoying double posting.

Briefly, the questions are:

(1) I am measuring the LCD to draw around 130mA when the backlight is on. I've measured this both on my custom board and the Sparkfun Carrier Board. I thought this was supposed to be closer to 40mA. anyone else seeing this, or have an explanation?

http://forum.lcdinfo.com/viewtopic.php?t=1613

(2) I am getting a strange problem in that my LCD won't display the pic I load into it on power-up; in fact it requires some number of resets to work at all. definitely not workable in the long-term, and i'm at a loss as to what's wrong...

http://forum.lcdinfo.com/viewtopic.php?t=1612

I guess it makes sense to post any repiles in the new topics? Again, sorry for the double-post. Hope you can help!

Hi from the Newbie

I know a little about robotics and a lot about BASIC Stamps. I don't really get how everyone hooks the LCD up to their computers. Also Is there any way to control these LCDs with a BASIC Stamp 2 and is there anyway to make RCA input for the LCD?

Hi. I've been playing with a Nokia LCD / Epson controller for several days. It's been working great, but suddenly started displaying a very bright/washed-out image. I was making tweaks to what I was displaying, nothing related to setup when this problem arose.

I'm setting to the same VOLCTR values that were working before. I've also tried scanning the entire volume range and everything is super-bright. (This used to go from very dark to very bright; now there's no dark.) I can see faint lines where the image I'm displaying has contrast between light and dark, but that's it.

I'm using Spark Fun's carrier board, on the side with the 8 connections (i.e. not using their voltage-boosting circuitry). I'm applying 3.3V to Vdig and Vdsp. I'm using a 5xNiMH pack for the LED V+. It is typically over 6V, and when fully charged reads about 7.1V.

If I swap another LCD onto the carrier board, that one looks fine (and the VOLCTR scan shows the expected dark-light range).

Before the "bad" LCD got to this state, it went through a too-bright phase where I was able to just make a change to VOLCTR to get back to a correct display -- I was using 28,3 for the params, and needed to switch to 28,0. As with this time, it was a sudden jump, fine one time, and way too bright after the next download (a few minutes later).

I measured the current draw on the LED V+ input to the LCD. On the working LCD, it was 28mA; on the too-bright LCD it was 22mA.

I'm downloading to an Atmel AVR controller via SPI, which also has those lines connected to the LCD. Could the random signals from the download have permanently reset something inside the LCD into a very weird state?!

So, did I fry the LED backlight by hooking it up to 7.1V?
Should I have added a current-limiting resistor to prevent this?

Any insight into what caused this and/or how to recover from it, or at least prevent damaging another one would be appreciated!

Thanks,
Cathy Saxton

I'm interested if you figured out any explanation for this ?

I don't think I can be of much help but I think I remember other people also having problems with washed out image with the Epson controller displays around the time when playing with these Nokia color lcds was quite new thing. Don't know if that was anything related to this. It might have been discussed somewhere in the beginning of this topic or maybe in some link (most likely the Yampp forum in that case).

Not yet... I didn't see anything in this forum that looked like it applied to my current situation. I did have the changing brightness issue that seems to be a result of using the 6V booster circuit on the Spark Fun breakout board. That's why I switched to a direct connection to the battery, which seemed to work well for a while.

I'll look for the Yampp forum to see if there's something there that may explain what's happening.
