I am current considering use of this display but have not ordered it yet. I am a little hesitant due to the number of users reporting problems with these displays. I am in the process of creating a PCB footprint for this display, but when applying the 3D model provided, the hole spacing of the display's connector pads do not appear to be on a 0.100" grid. Is this an error in the model or are the display's connector pins on a weird spacing? If so, what is the spacing? Any help would be much appreciated.

I had a project that needed some live data display, and looking for the cheapest low-power solution for our loggers lead me to the Nokia 5110 LCD. Once you get the backlight current under control, you can power the entire display from a digital pin, and if you use shiftout for soft SPI you can then get rid of the Reset and CS control lines. This brings the display down to any four wires you can spare on your build (incl. the power pin) and a ground line. This is much more manageable than what you see with the standard hookup guides if your mc is I/O limited like our pro-mini based loggers:

If you are looking for a tutorial on interfacing Arduino with Nokia 5110 LCD, then follow the below tutorial http://electronicshobbyists.com/interfacing-nokia-5110-lcd-with-arduino-nokia-5110-arduino-tutorial/

I got Conway's game of life running on this with only ~1k of RAM. was a really fun challenge.

I am trying to connect Nokia 5110 LCD to BeagleBone Black Rev-C over SPI protocol using Linux kernel's SPI driver.

I successfully installed and ran Adafruit's python-library: Adafruit_Nokia_LCD

I have a strange issue, when I run this python code first and then my C code, the code works perfect! But if I run my C code before the python code, I get no output. Logic says that the python code must be initializing something that I am missing in my code. Here's how I am initializing the LCD:

fd_spi_dev = open(device, O_RDWR);
//set mode
mode = SPI_MODE_0;
ioctl(fd_spi_dev, SPI_IOC_WR_MODE, &mode);
ioctl(fd_spi_dev, SPI_IOC_RD_MODE, &mode);
//set max bitrate
speed = 4000000;
ioctl(fd_spi_dev, SPI_IOC_RD_MAX_SPEED_HZ, &speed);
ioctl(fd_spi_dev, SPI_IOC_WR_MAX_SPEED_HZ, &speed);
// set an msb first
lsbsetting = 0;
ioctl(fd_spi_dev, SPI_IOC_WR_LSB_FIRST, &lsbsetting);
// set bits per word
bits = 8;
ioctl(fd_spi_dev, SPI_IOC_WR_BITS_PER_WORD, &bits);
ioctl(fd_spi_dev, SPI_IOC_RD_BITS_PER_WORD, &bits);
lcd_write_cmd(0x21);    // LCD extended commands
lcd_write_cmd(0xB8);    // set LCD Vop (contrast)
lcd_write_cmd(0x04);    // set temp coefficient
lcd_write_cmd(0x14);    // set biad mode 1:40
lcd_write_cmd(0x20);    // LCD basic commands
lcd_write_cmd(0x09);    // LCD all segments on
/* I am expecting to see all segments lit here */
sleep(5);
lcd_write_cmd(0x0C);    // LCD normal video 

void lcd_write_cmd(uint8_t cmd) {
    uint8_t *tx = &cmd;
    uint8_t rx;
    uint32_t len = 1;

struct spi_ioc_transfer tr = {
    .tx_buf = (uint32_t)tx,
    .rx_buf = (uint32_t)&rx,
    .len = len,
    .delay_usecs = delay,
    .speed_hz = speed,
    .bits_per_word = bits,
    .cs_change = 1,
     };

size = write(fd_dc_val, "0", 1);
size = write(fd_cs_val, "0", 1);

    ioctl(fd_spi_dev, SPI_IOC_MESSAGE(1), &tr);

write(fd_cs_val, "1", 1);
}

I am a novice in embedded programming. I would greatly appreciate any help. Thank you.

This LCD (I have the old-old kind) is absolutely my favorite. Yes, it has a board-to-glass connector that ranges from bad to abysmal, but it offers such a simple interface and so many pixels for so little money (obviously less if you buy only the panel.) Here are some clever things I've discovered:
Will fully operate on as little as 2.0V. That's power (Vdd) and i/o. It can be driven at 2MHz at these speeds; in fact, the LCD will work at even lower voltages but the contrast fades quickly and your microcontroller will likely approach its lower voltage limit too.
The initialization sequence is magic. Here it is, in case you were, like me, frustrated over and over again with varying sequences that others claimed to work but they didn't for you:
0x21, //switch to extended commands
0xE0, //set value of Vop (controls contrast) = 0x80 | 0x60 (arbitrary)
0x04, //set temperature coefficient
0x14, //set bias mode to 1:48.
0x20, //switch back to regular commands
0x0C, //enable normal display (dark on light), horizontal addressing
Reset/initialization can be picky - the datasheet says that the delay from power-up to reset mustn't exceed 30ms. What I found to be the best is to set SCE low and reset high at system bootup, wait 5ms for voltages to stabilize, lower reset, delay by ~1uS (1 nop @ 8MHz will do), raise reset then send it the initialization sequence above.
The LCD will work with the chip-select pin (SCE) tied to ground. This means that if it's the only device on the SPI bus, don't bother framing the i/o with a chip-select pin. If the bus is shared, frame the entire transaction, not every individual byte you send to the LCD. Interestingly, the display also seems to work fine with a floating Vdd pin - it must draw sufficient power just from i/o via clamping diodes; not surprising when you consider how low-power it is.
The Vout pin: Looks like you don't have to worry about it on this product, but the bare LCD will generate positive 6-9V on that pin. This wasn't totally clear to me from reading the datasheet.

I ran into an issue with the "Example Code." I noticed that the screen was not properly displaying Hello World! [the output was "Hfmmp Wpsme!"]

The fix is to add a spacer [",{}"] to the ASCII setup code like this...

,{0x00, 0x7f, 0x41, 0x41, 0x00} // 5b [
,{0x02, 0x04, 0x08, 0x10, 0x20} // 5c \
,{}
,{0x00, 0x41, 0x41, 0x7f, 0x00} // 5d ]
,{0x04, 0x02, 0x01, 0x02, 0x04} // 5e ^

Problems with my Display I just want to share my experience, maybe it can help others. I bought my display from eBay. A dirty cheap bargain from Hong Kong. I must say that it is exactly as the SFE breakout board, but of course, it didn't work. The problem I had was solid black display screen. No matter the combination of bias and contrast values that I set. The unit wasn't totally defective, because under a strong lamp light you could see the display trying to show the letters and pictures that are in the tutorial for Arduino that I got from SFE. Finally, after a long time of trials, I fixed it--> The problem: the bezel wasn't tight to the board, so the contacts of the display didn't work well. Conclusions: You get what you pay, don't expect well manufactured products and tested components comming from China at half the price you pay here. And second, it is totally no good idea to start up a new development with new technologies with untrusty material. Maybe you can try some cheap components after you are sure that you are used to certain technology (a display, a sensor, whatever), but don't try to break the barrier of new knowledge and tricky materials at the same time; because you won't be able to know who is the faulty.

Could someone please post a "hello world" code for Pic 16Fxxx? (MPLAB)
The Arduino code works fine for me, but I can't make any thing work with Pic. I found this code at http://www.sunbizhosting.com/~spiral/ , but can't figure out what I'm doing wrong.

Got it working using the 5V straight from the Arduino. Also used the 'Example Code' cited above, but modified the pin assignments to fit my setup.
You can check out my setup here.

Hello.
I am having problems to get this LCD working with Arduino
(I'm just a newbie)
I'm trying it with the first Arduino example, linked above, using the initialization sequence pointed by Kuy and Member197735 (thanks to both).
I have readed carefully all the comments, and recomendations. But I should be missing something.
I'm using voltage dividers to supply 3V in the inputs of the LCD, because of the Arduino works in 5V. LCD Vcc and LED are powered from the 3.3V output of the Arduino. The LCD only displayed something when I used: R1=470K,R2=820K. I have tried several values to obtain 3V, but the LCD showed nothing. I don't understand that.
This is my circuit and this and this is what the LCD is showing.
Any help would be very appreciated.
Thanks!

Why is the diode missing in the working example?

If you wanna make the first (simple) example code at http://www.arduino.cc/playground/Code/PCD8544 work you should add (in void LcdInitialise(void))
LcdWrite( LCD_CMD, 0x21 ); // LCD Extended Commands.
LcdWrite( LCD_CMD, 0xBf ); // Set LCD Vop (Contrast). //B1
LcdWrite( LCD_CMD, 0x04 ); // Set Temp coefficent. //0x04
LcdWrite( LCD_CMD, 0x14 ); // LCD bias mode 1:48. //0x13
LcdWrite( LCD_CMD, 0x0C ); // LCD in normal mode. 0x0d for inverse
(taken from the second code example) and also in the beginning of your code:

define LCD_CMD 0

On the page it says there is a 3D model for this part, but i can't find it in the repo

I'm interfacing this LCD with ATMEGA 32. Its been more than a week that I've been trying to get it right. All I get is the LED dimming effect. Here is my initialization code..

      CE=1;
 _delay_ms(1);
 RES=0;                     //RESET is pulled low.
 _delay_ms(1);
 RES=1;                     //Reset is pulled high

 CE=0;                      //Chip Select.
 _delay_ms(1);                                       //Enables serial transmission.

 SPI_command_write(0x21);   //Active mode, Address increasing on horizontal line and extended instruction set to be used.

 SPI_command_write(0x13);   //Set voltage Bias System. n=4,1:48.CHECK.Optimum value selected.

 SPI_command_write(0xC0);   //Vop=5v.

 SPI_command_write(0x06);   //Temperature co-efficient of IC Selected. CHECK.

 SPI_command_write(0x20);   //Basic mode selected.Extended instruction set not used.

 SPI_command_write(0x0C);   //Display Results in normal mode.

 SPI_command_write(0x42);        //Yaddress

 SPI_command_write(0x85);        //Xaddress

Has anyone played around with minimum and maximum SPI clock rates with this display? I know the datasheet says up to 4 Mbit/s, but assuming this display is the only thing on the particular SPI bus, what's a good minimum clock rate before you might start to notice delay in the display refresh? I mean TVs are 60 Hz - 120Hz.

I have a similar board made by mib-instruments and bought from ebay years ago. It has been my standard spi test tool because it's so easy to work with. http://www.ebay.com/itm/Nokia-5110-LCD-84x84-dot-martix-backlight-PCB-RED-/320684678723 (specs http://i1119.photobucket.com/albums/k636/mib_instruments/diy/LCDC2A0SPEC.jpg)

I wanted another one so i bought the sparkfun item but it doesn't quite work: it flickers and blackens occasionally but my graphic never shows up. Is there a bulletproof arduino sketch I could use to test it?

I almost have it working satisfactorily but I find that the bottom 1/5th of the screen does not function correctly. Sometimes it has some random blocks that are black, most of the time it is blank. I am not sure what would cause this. Is it safe to assume it is a defect on this module? I also noticed sometimes it randomly cuts off vertical segments of letters (but not every time!) I believe the letters would be written vertically in the examples. Is it possible that the arduino is sending commands too quickly?

These LCD's need cleaning. I have an average failure rate of about 15-20% on delivery. The most common problem is that the contrast is too high, and there's constant flickering / changing of contrast compared to the other 80% of them.

The solution is fairly simple, unclip the LCD from it's board and clean the pads on the PCB with 99% IPA. Then remove the lcd back plate and contact bar. Sometimes the contact bar is stuck fairly well to the glass, peel off carefully. Clean the contacts on the LCD glass with IPA, if any residue from the contacts is left on, rub it off carefully with IPA / tissue.

Clean the contact bar with IPA both sides.

Reassemble, making sure you don't have even the smallest spec of dust on the bar or contacts. The slightest spec will cause the bar to raise slightly, and that and adjacent contacts to not make contact, or be intermittent.

I think the root issue is non-clean assembly, flux on the pads and dust.

Given that these units are previously loved displays, probably general muck / grime doesn't help either.

Also gold contacts on the PCB instead of tinned would help with contact.

Hey, it's great you did a 3D model of this display, but how about an Eagle entry in the library so we can use it there too?

I love this little display! I wanted to be able to create images for it but nothing I saw did exactly what I wanted. So I wrote a processing sketch that creates 84x48 squares on the screen and allows you to click to turn them on or off. Also has buttons to invert, move up/down/left/right, and flip horizontally/vertically. Then, it saves the hex data to a text file to copy to your code. You can also load an image (any size, any colors) and it will scale it, convert to b/w, then put it in the rest of the program so that you can alter the pixels or move it. It isn't perfect for every occasion but I've found it useful and I hope others might too. It is heavily commented so it should be easy to figure things out and change them if you want something different. http://thewanderingengineer.com/2014/07/12/nokia-5110-screen-photo-to-bitmap-converter/

I've got 3 of these and wired them up as suggested in the hookup guide and downloaded the example code, and the only thing that seems to work is brightening and dimming the LED. I've started again from scratch at least twice, tried all 3 units, and verified all the connections match the hookup guide, and I still the ssame result; no graphics, no text, just a border. Any ideas as to what might be wrong?

Anyone taken these things apart yet? You know the flexible rectangular blocky thing that connects the contact pad on the board to the LCD itself? What are these called?

Got mine running last night and found two problems with the code, one of which was the backslash a couple of others have already noted. Second was that the LCDCharacter() writes two blank vertical lines, one before the character and a second after, when only one is needed. Without the extra blank you get at least one additional character on each line. I'll probably also move the ASCII font table to PROGMEM space to save on RAM and then start to work on some big digits for a clock.

I'm using this LCD for a large Arduino UNO project, but I'm running out of SRAM memory space. I was wondering if I used PROGMEM on the LCD ASCII array if that would help. If so, does anyone know what the right code for this would be? After looking through a lot of PROGMEM examples, I'm not advance enough to really grasp everything that's going on. Any help you can give would be a great help. Thanks in advance!

I used one of these LCDs with an Arduino to display GPS information. I wrote a few functions that can display large numbers (28 px high) if anyone is interested, this lets me display speed, heading etc. A writeup of my project is here: http://mechinations.wordpress.com/2014/04/07/gps-sailing/

These are great displays. I ran into a problem using them with the nRF24L01+ radio transciever, which requires the use of the SPI bus. If one attaches both the radio and the display MOSI and SCK pins to pins 13 and 11 as instructed in the hookup guide, the SPI traffic of the other device (in this case the nRF24L01+ radio) will prevent the display from functioning. The easy solution is to move the Nokia 5110 MOSI and SCK pins to any other digital pin. This should be made clear in the hookup guide, where it says there is no choice but to use the hardware SPI pins for the display. I found out that is not true at all. I hope his helps others with the same problem. Despite the occasional bad display these carry much more information that the comparably prices 16 x 2 LCD and use fewer pins too boot. What a deal!

I was able to get this work only after using 5v, and lowering the contrast by int from 55 to 45 to remove the "black box" flickering behind the screen drawings. When I power with 3.3v, nothing - just the LED and dimming etc of the screen. I'd love to use 3.3v (and it seems based on responses here) that it should run only on 3.3v. Any ideas anyone?

I was wondering if anyone had happened to convert this demo file to a library for easy use? I would love to do it myself but unfortunately I am not very good at it.

The LCD works great, but i cannot open the c4d file you provide at your github repo

Does anyone know if you can remove the LCD from its housing and do things like flip or remove the polarizer?

Hello people, is there anyone that can tell me the height of this display. I mean the displays height 45x45 mm is the size but i wonder the thickness of it. Only the display not the pcb. I couldn't find this info on the datasheet. Best Regards..

This is a great display for the money, certainly the best bang for the buck of you can live with B&W and lower res graphics. I have a lcd driver for Arduino I will post on http://www.marchdvd.com/5110 so take a look there it draws text aligned on pixels boundaries of 8 and draws lines and has invert video options.

The example code does not seem to allow me to use bitmap arrays smaller than 84x48! Does anyone know of a solution to do this?

I just started messing around with this LCD using a STM32F103 microcontroller running at 72MHz... it works great. The only problem I had, and I suspect others might have if they are using fast processors, is that you have to deliberately introduce the setup and hold time delays on the DC pin... if you don't you will get spurious pixels written to the display. I used a delay of 10uS, although the spec says 100nS is fine.

Anyway, just hope to save anyone else a little trouble...

Hey guys, i keep getting errors with the Example Code: 'PCD8544' does not name a type

It highlights this line: PCD8544 nokia = PCD8544(3,4,5,7,6);

I have connected the libraries properly. Can someone tell me how i can make the expample code work again?

No schematic or Eagle files?

Mine has a 5th mounting hole near 8-LED on the silkscreen that I don't see in any pictures

Hey guys, if you are interested I managed to run this LCD on a Raspberry Pi :D Nokia 5110 Raspberry Pi

Just a heads up to anyone trying to run the Arduino example. Make sure you plug Vcc into the 3.3V output on the arduino board. I also had to change the line

" LcdWrite(LCD_C, 0x14 ); // LCD bias mode 1:48. //0x13 "

to

" LcdWrite(LCD_C, 0x12 ); // LCD bias mode 1:48. //0x13 "

Otherwise the screen was completely dark and unreadable.

Great lcd! The only problem I have is the lcd sometimes displays lines of grayscale pixels down the screen when the pixels are unevenly lit

Will I be needing a logic level converter to run on a 5v Arduino?

I been trying to display 8-10 images as an animation. The individual images all work, but when I trey more than 8 images, nothing happens on the screen, and above 2 images, I get errors in the drawing of the images. Is there some kind of buffer or violent reset I can do so that the data doesnt get jumbled up?

Can someone help me edit the code in the arduino example to display readings from a sensor, I've looked through all of the links and searched through the Internet but I couldn't find an example anywhere, it would really help me if someone could tell me how to do this.

Has someone already been able to get this display to work with an Arduino Due? For some reason I cannot get it to work while it does work perfectly on my Mega. Any ideas why it may not work?

Added a driver for this display to the object-oriented arduino platform; Cosa. Please find example code at https://github.com/mikaelpatel/Cosa/blob/master/examples/Drivers/CosaPCD8544/CosaPCD8544.ino and source code at https://github.com/mikaelpatel/Cosa/blob/master/Cosa/IOStream/Driver/PCD8544.hh.

This driver supports iostream output with form feed, new line and backspace. It also supports drawing of icons and histogram bars. See the example code.

Have fun.

I just spent the last couple hours struggling with this LCD because of something very stupid of me. I was using an atmega328p in AVR-GCC and using hardware SPI. Thinking i didn't need MISO I hooked it to DC. The LCD worked absolutely fine until I tried to set the x and y position in the ram. It started acting weird every time I tried it. Finally I put dc to another pin and BAM NO PROBLEMS. Looking back I feel pretty stupid but hopefully this post will save someone else the same mistake. Other than that great LCD for my projects

I made up a short tutorial on how to drive the display with the 5V arduino using a voltage divider - use on your own risk: http://arduinoandsoftware.wordpress.com/2012/12/30/nokia-33105110-3-3v-display-with-5v-arduino/

Is there any data on power consumption? I need to estimate the power consumption when running everything on 3 V.

My screen was bought from Microcenter on 10/14/2012. It works via the example. Said screen was the retail packaging variety.

How would i tell the lcd to start on a new line? would i say lcdstringln?

I need to know where to drill the mounting holes in a board I'm designing, can someone get more precise measurements of the physical dimensions of this board?

I used the ASCII font given in the example code in one of my projects and ran across a mystifying bug. I was developing code on a PIC12F675 to drive an OLED through its SPI interface. (Yes there are enough pins and memory to do this!) I was using the HI_TECH C compiler and tried several different approaches and never could get the "]" character to display. After pulling what is left of my hair out for 2 days, I realized there was a "\" in the comment for the previous line of the ASCII font definition which caused the compiler to treat the array entry for ] as a comment! Just replace the "// 5c \" comment with "//5c backslash" and everything works! I don't know if this effect is peculiar to the HI-TECH compiler only.

Member #341079 I have the EXACT same problem with the display...the misterious fade to black... Anyone have found a fix for it yet?

C ya

The Energia folks have an example program for this LCD and the TI Launchpad written using their Arduino style tooling. I've updated their example and added the ability to report back the temperature over a UART. It is a very simple hardware setup since both systems are 3.3v. http://joe.blog.freemansoft.com/2012/08/digital-thermometer-with-ti-lanchpad.html

P.S.

I can't get the Example Code on this page to compile either...

The errors are:-

Adafruit_PCD8544.cpp: In member function 'void Adafruit_PCD8544::begin(uint8_t)': Adafruit_PCD8544.cpp:155: error: 'digitalPinToPort' was not declared in this scope Adafruit_PCD8544.cpp:155: error: 'portOutputRegister' was not declared in this scope Adafruit_PCD8544.cpp:156: error: 'digitalPinToBitMask' was not declared in this scope

Surely "Example Code" should run straight out of the box?

Having Problems...

Despite my earlier post, I'm now having problems with these didplays as I come to try and actually use them.

I'm running with an Arduino Uno R3 and using voltage dividers on the signal lines for the hardware setup.

1) There seems to be a serious issue related to contrast and/or connections between the display and the breakout board. When running "Black on White" text, the background gradually darkens to a black rectangle covering the etire display area but will revert to normal if the centre of the metal surround is squeezed towards the pcb, however, putting a sprig clip on it to keep it comoressed doesn't seem to cure the problem, but just slows the raste at which it fails - waggle it and it comes good again.

2) I'm really struggling to find unformation on using this display with the Arduino. The example (pcdtest.pde) provided with the Adafruit libraries (Adafruit_PCD8544 and Adafruit_GFX) won't even compile and the only library I have found that I can make any sense of using is the PCD8544 library from Google (http://code.google.com/p/pcd8544/downloads/detail?name=PCD8544-1.4.zip) and I can't really uderstand how to do graphics with that.

I did find another example (did't save it and can't find it again) that worked with the Adafruit libraries as it was supplied (including graphics), but trying to change it in any way beyond changing the text of the "Hello World !" string (which actually shoed on screen as "Hffmmp Wpsme !", so obviously a coding problem there!!!) just locked everythig up.

I tried using the "LCDAssistant" package to create a logo from a graphic that I resized to a b&w jpg of 84x48 but every byte generated was 0x00 so that was not right. I tried fiddling with the settings (flying blind) but still got nowhere - does anybody know the settings for LCDAssistant and this display and has used it successfully?

Maybe some of the answers are on here somewhere but, frankly, I don't understand a lot of what is being said - I'm a very old dog, who is struggling badly with new tricks...

Any help or advice appreciated, thanks.

I have purchased a couple of these from Proto-Pic in the UK to build an Arduino-based test device for use in my workshop.

One of the things that I test regularly is a commercial item that features a 16x4 (HD44780) display. Currently I have a 20x4 on a flying lead that I plug in to determine if a display failure is down the lcd display or the main board.

Is there any way to get the 5110 Graphic Display to work with signals that were feeding to an HD44780? - if I could build that in then I would have a complete multi-testing set up in one box.

I'm very out of date hadrware-wise (I was out of electronics for 30 years) and I'm not a programmerby any stretch of the imagiation (even a relatively simple sketch takes hours eliminating the errors one by one).

I have the other test functions working ok by using the library and cobbling together code from projects I've found on the web (very inefficent coding when put together I'm sure, but it works) but I'd dearly love to add this extra functionality.

Can anybody help?

Thanks

Duncan

I am using arduino example and while i am getting proper images and text i also get some odd horizontal flickering. It looks like several horizantal lines across the screen on the background with image/text on foreground. I tried switching to only use digital pins on my arduino leonardo but i still see this behaviour. Any ideas?

Hello! This LCD was able to be operated on this weekend. The Datasheet, the Arduino Example, the Quickstart Guide and the Example Code were very useful. I wish to express my gratitude to you of the author of the article. Thank you!

I have found the eagle library! Go here:

--> http://cadsoft.de/downloads/file/lph-7366.lbr

Is there mechanical documentation for this (location of mounting holes, location of screen relative to board, etc)? Yes, I can measure it but I'm lazy...

would this work with the pro mini

would this work with the pro mini

It works quite easily (if you pay attention to the voltage advice).

I only had a little problem showing lower case chars when using the example code but it seemed to be a problem with the comment "// 5c \". Once the backslash was removed everything was working as expected. Great display, I think I'm going to get a bunch of these.

Is it possible to display text on this? If so, how?

Thanks.

at adafruit they say that you need a level shifter that they include. Im confused it seems like no one here is using one. whats the deal?

Here is one way to control the 5110 LCD display with a Launchpad.

I see that this item is Out of Stock (back-order allowed). I have a embedded system I have been documenting / publishing the design for over the last month, so I would like to know if Sparkfun Plans on keeping this part and if so for how long? Is there a part you would recommend for replacement if this one is going away?
Thanks!

What is the usable display size for this screen? (Dimensions were there are pixels.)

LadyAda has a nice write-up on how to use this here; http://ladyada.net/products/nokia5110/
It's roughly the same price on both sites.
BTW; I'm not advertising; i'm just trying to help out- it helped me!

Might I suggest you (SFE) source some of the Electronic Assembly's LCD Dog-S series. I think they would be a step up from these at a reduced price. I don't think that they website is up to date, but their part number is LED39x41-GR.
edit: Correction, that is the part number for the backlight module. The LCD is DOGS102W-6.

I recently completed a port of the Arduino GLCD library for the PCD8544 using one of these displays. You can find it here:
git@github.com:MikeSmith/glcd_pcd8544.git
In conjunction with M2TK this gets you a fairly respectable graphics library and a forms-based menu system on your tiny device. Woot!

I just got 2 of these. Haven't had a chance to hook them up yet. But I gather that the LEDs are green. Has anyone managed to lift up the display and change the LEDs for white or other color?

What does the VOUT pin do?

I made a little font generator for the Nokia 5110 in the processing programming language (processing.org). It allows you to convert any font and any character that you can display on the screen into a list of hex codes that can be directly used in an embedded system (I'm using msp430). Just type a character and the corresponding hex codes will be in your clipboard and you can copy them into your program. It starts with an example with the chinese character for 5. It should work on any system that can run processing (e.g. mac osx).

all the nokia 5110 lcd i recieved, i have noticed that the RED PCB is a bit bended.
I have 6 of them. I have only test 2 of those and they work fine.
I dont know why they are noticeably bended.

I finally got around to running this LCD on my 3310 PCB. It is working fine with one minor problem. The SF 3310 display hides to first line of bytes for some reason and I had to offset everything to compensate. The 5110 doesn't do this as behaves as expected. I haven't heard anyone else report this so maybe my initialization code is different.
My fix.

ifdef lcd3310

SendLcd(LCDCommand,0x40 | ++RAMY);   //row - row zero is hidden so inc  

endif

ifdef lcd5110

SendLcd(LCDCommand,0x40 | RAMY);  

endif

I found the LCD bias value must be set to 0x15 to get good constrast consistently.
Using a 3V source, my LCD often worked OK using bias 0x14 like the other examples, but sometimes it would appear gray and faded. The fading would lessen if I touched the panel lightly with my hand for a few seconds, then let go, so maybe it's a temperature-dependent thing?
After writing a program to let me interactively adjust Vop, temperature coefficient, and bias, and experimenting with different values, I found that bias 0x15 worked much, much better than 0x14. I'm also using Vop 0xD0 and temperature coeff 0x04, but those don't seem to matter as much.
I also noticed an error that's repeated in many of the examples:
0x14, //set bias mode to 1:48.
0x14 is not 1:48 bias. If you read the datasheet on the top of page 16, 0x14 corresponds to a bias of 1:40/1:34. If you want 1:48 bias as the comment says, use 0x13. The 0x15 value I'm using corresponds to 1:24 bias.

If you are having problems with the black pixels in images/warping PCB, use original Nokia 5110, I happened to have one at home and it works as it should, no bad connections degrading image quality.

Does anyone know whether this can be stripped of its backing so it can be used in transmission? I would love to use this as a modulator for a laser beam. Or if someone knows a similarly cheap transmission LCD that would be fine too.

Has anyone created an eagle footprint for this? I'll be doing so when the order arrives. Basically just the outline with mounting holes and the 8 pin header.

This lcd is so easy to use!
For those of the arduino persuasion, I wrapped some simple methods up in a library based on this arduino page http://www.arduino.cc/playground/Code/PCD8544.
This is my first library for arduino but I hope it's useful to someone. Check it out here:

Stuck. Blank LCD. Added 0x20, changed Vop to 0xB3. Guessing connections may be the issue? 3.3v for LED and VCC. GND to GND. Remainder connected to Arduino via voltage dividers. What am I doing wrong?

This is a great little lcd. When I first wired it up, the backlight was shorted (accidentally) against my 5v rail, so i got some magic smoke, and burnt to LEDs but it re-soldered the offending joints and it works very well now. Something to note: the refresh and write times are much, much slower if you use 5 volt logic. I stuck in a logic level converter and it ran at least 5x faster.

A couple things:
first off, the best contrast setting for the unit I received was B3. This can be done like this:
LcdWrite( LCD_CMD, 0xB3 );
You can also use FastLCD to convert your bitmaps - google it. It outputs BASIC code, but you just search and replace &h to 0x and you're grand. It has the added advantage of being an editor for touching up output.

I recently obtained a virtually identical LCD from a Nokia 5160, and although its backlight LEDs are green, not white and conversely use different voltages, I had success hooking up the LEDs' Vcc pin to a PWM capable pin on the microcontroller, allowing me to control backlight intensity (I didn't need a current limiting resistor for this either, but adding one will help reduce current drain on the controller).

Seems like the PCD8544 library does it's own SPI bit managing and it really doesn't like me using the SD library (also talks SPI) at the same time. I've made sure I've got all the SPI pins matching for both libraries (MISO, MOSI, Clock are the same and each device has it's own Select), but it looks like the SD.begin() call just breaks the SPI bus for the 5110 and it becomes non-responsive. The LCD works just fine if I don't initialize the SD library and the SD card works fine if I do initialize the SD card.
Anyone have any experience using this LCD with another SPI device? How did you keep everything happy?
Thanks!

I accidentally (well, intentionally, but stupidly) plugged the LED backlight line directly into 5V when I first got this, and I saw (and smelled) the magic black smoke escape. I believe the black smoke only came from one of the backlight LEDs burning out, because I only notice one of them not working now. The other backlight LEDs still light up okay, but I also now seem to be having trouble getting the display to show anything. I'm just wondering if I could have messed anything else up. It seems like others have had their issues with this display, so I was hoping I maybe had something misconfigured. I'm fairly certain I have the pins assigned properly, but maybe I'll tinker with the contrast. Any recommendations for setting the contrast value?
I'm using a Teensy 1.0 as a Teensyduino, and everything runs at 5V logic.
Any ideas, tips, recommendations?

The code is unportable for the MSP430 using C. :/

i try example for arduino... i change pin... but it not worked...
Who ever started this screen? can you publish simple worked example?

Anyone have any example code for PicAxe please? Thanks much! Andrew

As much as I love SFE products and will continue to order from them, this is one product I would not recommend. The connection between the LCD unit itself and the carrier board is via those rubber polymer connectors. All the planets must line up properly for them to work. In this case, the carrier board was warped preventing the connection from working. You will find other such remarks in the comments area.
I wish I could have gotten this to work because it was the perfect match to my needs (other than that it had to work!).

I've followed the linked-to Arduino example and I get nothing on the display. Should it just work without any other components? The link mentions a possible cap on VOUT but there's no such pin. Googling has suggested my Duemilanove's digital pins will be @5V but I need 3.3V?
I have connected LCD:Arduino as
VCC:3V3
GND:GND
SCE:7
RST:6
D/C:5
DN(MOSI):4 is this "SDIN"??
SCLK:3
any help would be appreciated, thanks!

Is there a way to control contrast?
My display shows all dark, with the text darker... Not quite optimal.

Are there available pcb dimensions? At least pitch between holes and pcb connection..... Thanks.

I bought one of these that has the problem where you have to squeeze the top to make it work. Is there any way to fix it? If I take off the aluminium bezel am I in for a hard time?

Would you guys offer bare PCB? Or .brd file.
Thank You

Has anyone controlled this LCD via a Picaxe processor?

After working out a messy voltage divider for all of the inputs to this guy, I figured I would share a drawing of my breadboard for anybody else who wanted a pre-done example of how to set it up:
nokia5110_bb.png
I'm sure there are better ways to do it, but this one is working for me right now.

I got this little screen for my Netduino but it just won't work! I've tried everything, and even worked on it with someone who had the same screen but it won't work. We got it all right, but it just won't work. If anyone here gets it to work with the netduino please let me know.
EDIT: It is now working go here: http://forums.netduino.com/index.php?/topic/860-lcd-help-needed-16x2s-are-boring/page__st__20

Yes, it does have a backlight. I have several of these, be careful to only give 3.3v or else it will be toast!

Do you have an eagle schematic for this?

Hi, I just bought this wonderful LCD but I'm having huge huge problems connecting it..could anyone please point me in the right direction? Since there are pins that aren't metioned in the code, for example the 6 - DNK(MOSI)...
Help please..
Regards
ps: I'm using it with a Arduino UNO, so I have the 3.3V pin...

I have been running this at 5V with no problems, I have not been using the back light. Love this thing, need a few more. @ 5v mine pulls about 1ma. Not to bad.This + openlog + atmega328 @8 mhz = 10-12ma max this is so cool.

It looks like the board just has 4 white LEDs in parallel and no current limiting resistors. To drive them safely from 5V you should probably use something along the lines of at least a 22 Ohm resistor which should limit the current to 80mA (20mA per LED).

Thanks Sparkfun! Good to be able to buy it as a standalone display at a reasonable price.

Does anyone know the diode rating and package size, also does anyone know where to get the rubber ferroius connector behind the LCD mine is defective. Has anyone come into issues with the breadboard the LCD is connected to, a few aren't working for me.

How do i wire this up to my arduino as the pins on the example do not match the pins on the board

FWIW I have connected this LCD with a 5V power supply to a 5V Arduino board with no level conversion and it worked. Presumably this may reduce the lifetime of the LCD.
According to the Datasheet this is operating within the "Limiting Values" listed on page 17 of the driver IC. "Stresses above those listed under limiting values may cause permanent damage to the device."

Can we have some data on the LED pin?

I made some changes/additions to the example code linked above. The main addition is a function that makes it easy to turn individual pixels on/off.<br />
<br />
The code is here: https://github.com/centerblack/PCD8544_Arduino/blob/master/PCD8544.pde<br />
<br />
There's some examples of drawing a world map, lines, rectangles, etc.

Is there any more documentation available for the additions to the LCD? For example, the datasheet has no information (that I could find, at least) on the LED. Everything seems fine on 3.3V, but what is the current limit on the LED? (note: if it wasn't for work, I would just mess around with it myself.)<br />
<br />
Thanks,

The datasheet and examples imply that this runs on 3.3V, but I don't see it mentioned explicitly anywhere. Is that correct?

If you want to wire up several up these to a single microcontroller, you might take advantage of my freshly GPL'd C++ driver library for PCD8544 devices. It's templated, so you can avoid duplicating code all over the place. Here's a picture of two PCD8544 screens running off of an ATmega328. (The screens are operating independently, even though they happen to be showing the same logo graphic in that picture.)<br />
<br />
<br />

Here's an AVR example in C: http://pastie.org/1332371<br />
It's for the ATtiny2313 but it should work with just about any AVR.

Here is a PicBasic Pro example for the 3310, which should be compatible with the 5110. http://www.picbasic.co.uk/forum/content.php?r=174-Using-Nokia-3310-LCD

Fantastic! It appears from your example link that this uses the same controller as the Nokia 3310 that I've already used in past projects. The only thing that made it so cumbersome was trying to connect to its fine pitch press on type connector. This gives me a great low cost display option that is easy to connect to.
If anyone doesn't have experience with this LCD, take a peak at the Arduino example link above to see just how easy it is to use. If you use plain C on your AVRs, I have sample code on http://tinkerish.com.
Great job sparkfun!

I would like to know the measures of the board/LCD. Also I would like to know the schematic and if the LCD have back light.
Thanks.
