5110 lcd module quotation

We have published quite a number of tutorials using different displays with the Arduino, with the most recent being the tutorial on displaying graphics on all kind of displays with Arduino. For today’s tutorial, we will look into achieving more with displays by implementing a menu based system with the Nokia 5110 LCD display and the Arduino. The menu is one of the easiest and most intuitive ways through which users interact with products that require navigation. From mobile phone to PCs, its applications are endless. Today we will explore how to add this cool feature to your Arduino project.

At the heart of today’s project is the Nokia 5110 LCD Display. The Nokia 5110 LCD is one of the most popular LCD display among makers. It was originally developed for use as a screen for cell phones and was used in lots of mobile phones during the 90’s. The display uses a low power CMOS LCD controller/driver, the PCD8544, which drives the 84×48px graphics display. In a normal state, the display consumes about 6 to 7mA which makes it quite ideal for low power devices. We have published quite a number of tutorials on this display that might help you understand how to drive such a display.

To make the schematics easy to follow, a pin map of the connection between the Arduino Uno and the Nokia 5110, which isthe major component, is shown below.

To be fair, the code for today’s tutorial is a little bit complex and while I will do my best to break it down and ensure you understand the basics, it might take you building your own menu to fully grab the concept. The code for today is heavily dependent on two major libraries; The Adafruit GFX library and the Adafruit Nokia 5110 LCD Library. The Adafruit GFX library is probably one of the libraries we use the most in our tutorials. It makes it easy to display graphics and perform simple animations on supported displays. The Nokia 5110 LCD library, on the other hand, reduces the amount of work and code required to interact with the LCD.

We start the code as with other sketches by including all the libraries required for the project which in this case, are the Adafruit GFX and Nokia 5110 LCD libraries.

Next, we write the void setup function. Here we declare all the pins to which the push buttons are connected as inputs and set digital pin 7 as output since the Light pin of the LCD is connected to it. This pin will be used to turn the backlight on/off later on.

Go through the schematics one more time to ensure everything is connected as it should be, then connect the Arduino to your computer and upload the code. After a couple of seconds, you should see the menu displayed on the LCD and it should respond to the push buttons when pressed.

In the previous tutorial I showed how to build a weather station using DHT11 and BMP180 with an Arduino. However, the project has a downside which is the power consumption of the 16X2 LCD. If we were building a battery powered project with the desire to last for several weeks and probably several months, like a weather station for instance, then we’ll have to replace the LCD keypad shield from the previous tutorials and go for something like the low powered Nokia 5110 84×84 LCD display. In this tutorial I will be showing you how to drive this display with the Arduino and thus build projects with longer battery life.

Since we are just going to drive the display we won’t be needing sensors for this tutorial, however we will need the components listed below which include the Nokia 5110 itself and we will show how to drive the display using an Arduino board.

The Nokia 5110 display is basically a graphic LCD display useful for a lot of applications. It was intended originally to be used as a screen for cell phones and was used in lots of mobile phones during the 90’s. This display uses a low powered CMOS LCD controller/driver PCD8544, which drives the graphic display of size 84×48. It is very cheap and costs about 3$. You can get one here.

The Nokia 5110 LCD can display text, graphics as well as bitmaps. When this display is fully lit, it draws about 10mA but with the backlight off, it draws as low as 0.4mA. The power consumed by this display is very low compared to that of the keypad LCD shield used in the previous tutorial. I will be using the Arduino Mega for this tutorial as usual and you can buy one here. You can also buy jumpers, breadboards and power bank which you will be needing for this tutorial.

Before we start writing the code for this project, first we need to download the 5110 LCD graph library that was made by rinky-dink electronics. The library does most of the heavy lifting and makes it easy for us o use the LCD. Click here to visit the download page and then download the LCD5110_graph zip file. When done, unzip the file to your preferred location and then rename the unzipped folder to something simple like “LCD5110”. Copy and paste this folder in your arduino library folder, then run your arduino IDE.

Click on the file, then on examples and then click on LCD5110. Since we are using the Arduino Mega, under the LCD5110 drop down click on Arduino (AVR) and the open up the LCD graph demo file.

The first line after the comment section, the LCD5110 library was included and after that a myGLCD object was created with the numbers being the pins to which the LCD is connected. The last two values in the myGLCD object is the RST and CS values which has been changed as explained initially.

with this done, we move to the setup function. In the setup function, the InitLCD method is used to initialize the display and this method takes in a parameter for the display contrast. The contrast value is between 0-127 and since we didn’t pass in any value the default value which is 70 will be used. Next, the setFont method is called which sets smallFont as the display font style is called and lastly, the randomSeed function which is used to initialize the random number generator using analogRead on an unconnected pin as a random input.

Most of the functions used in the project have names that are self-explanatory like myGLCD.drawLine needs no explanation for instance as its clear the function draws a line.

Here is the full code for this project. Its an example from the Library named LCD5110_Graph_Demo and how to get to it has been described at the beginning of this section.

Are you bored by making those projects that don’t grab your interest? And, that’s why feeling demotivated? And are you looking for some interesting project that excites and motivates you? You’re in the right spot. Because, In this tutorial, we’ll interface “Nokia 5110 LCD with Arduino UNO” The Nokia 5110 LCD is one of the devices that are used to display words, numbers, images, etc. The reason to use Nokia LCD is that it’s inexpensive and easily get interfaced with Arduino.

Nokia 5110 is a simple graphic LCD. Initially, it was made to use as a mobile phone screen. The LCD contains the PCD8544 controller in it. Practically, it’s a low-powered controller. This controller was designed to display 48 rows and 84 cols on an LCD screen. The LCD is easy to solder and mount on board. Also, it’s easy to interface with any microcontroller.

Assemble the circuit to interface “Nokia 5110 LCD with Arduino UNO” according to the above-given diagram. Upload the code in Arduino. When you upload the code in it, the Arduino transfers it to the LCD through wires/buses. And, you will see that LCD will display “Hello World”. Use the potentiometer to increase or decrease the light intensity.

In the void setup, initialize the LCD by Lcd.begin(84, 48). Remember, that this 84 and 48 is the dimension of LCD. Then createchar( ) is used to create the character fonts for the LED matrices.

Here I’ve added a the 5110 LCD to a logger recording data from a BME280 & Tipping Bucket Rain gauge. If the BME  survives in our field environment, this will become a standard configuration for our climate stations. I

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:

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 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.

(5) If you are using a PIC to run ths thing, and using the PIC"s USART or EUSART in a synchronous mode, be sure to note that the LCD controller expects the MSBit of each byte to be transmitted first on the serial line. The PIC 18F EUSART transmits the LSBit first. For now, I have lots of extra code space, so I"ve wasted a 256-byte section on a lookup table that reverses the bits in a byte. This way, I just write my initialization code normally, and I have a TransmitCommandByte() function that looks up every byte it sends so I don"t have to think about that.

Thank you! I"m not quite sure I do want an LCD yet, to be honest, I"m just considering the different options available. I"ll check out the Sharp component, thanks!

Advice for others: It took me quite a while to get this working on an ARM Cortex. Since there is no way to read from the LCD, it is very hard to know if SPI is working without doing everything perfectly. SO:

If the LCD module is soldered to another board and the two top screws installed and tightened carefully to pull the bow out of the module it seems to prevent (or solve) the problem.

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.

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;

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 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?

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.

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/

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!

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.

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.

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

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

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?

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.

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.

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).

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.

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?

Ack! After two days of working nicely with 0x15 bias, I reset the board today, and the LCD appeared way over-dark. I changed the bias back to 0x14 and it looks perfect. What the heck?! I think there must be some temperature-sensing or temperature-dependence going on, so the same init values may produce good-looking results one day but not the next.

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.

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.

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.

I"m pretty sure I tracked down the problem- the PCD8544 library uses software SPI while the SD library uses hardware SPI and I"m pretty sure the Arduino can"t do both over the same SPI clock/miso/mosi pins. Anyone know if this LCD will work with hardware SPI?

I"ve had issues with the LCD not showing anything intermittently. You got to make sure that all the connections are secure, and for the reset pulse, be sure to have a delay that"s 30-50 milliseconds long.

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.

Don"t do this. Each divider will be burning 20x the entire amount of current that the display needs to function, and the whole assembly will waste 100x the LCD"s needed power and many, many times more than even the atmega needs to run at full speed. This will kill battery life.

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)...

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.

Yes, we have noticed that the PCB was bowing and as a result the LCD now only works when we press down on the metal strip at the top. I hope that only a small number of these LCDs have this problem. We"re expecting a shipment to arrive today, I will be running more tests.

Edit: After leaving glue to dry overnight, LCD simply does not turn on anymore. All the connections are good, but absolutely nothing shows on the LCD now at all. Only the LEDs come on.

Did you get either of the LCDs to display anything, at any time? Is it possible that the connections were OK, but you were not initializing or driving them correctly? Or did they start to work at one point, and then fail at some later point?

Note that the backlight LED"s are soldered onto the breakout board, and have nothing to do with the circuitry of the controller and LCD. So just because the backlights are shining doesn"t tell you anything about the operability of the LCD itself.

It depends on the code that you are using to control the LCD. If you are using the Arduino example above, the pins are defined in the beginning of the code.

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.

I am attempting to use this with a Duemilanove (ATmega328). Up til now, I have been powering it with the 3.3V line, including the LED. The datasheet for the LDC claims: "VDDmax = 5 V if LCD supply voltage is internally generated (voltage generator enabled)." The logic levels should be kept from 2.7V to 3.3V. Since the Duemilanove uses 5V logic levels, I am using a simple voltage divider on the communication line with no issues.

The maximum logic value of 3.3 volts made me cautious of driving the LCDs at the native 5 volts of my Teensy AVR. That said, running purely off 5 volts seems to do no harm to the LCD.

For those interested, I have taken a few measurements of the current draw of the LED backlight of my LCD. As I said earlier, powering the LED with 5V external has caused permanent damage to one, perhaps two of the four LEDs. So, use the following graph at your own risk.

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.)

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

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.

The name of this product itself is enough to explain its origin. Yes of course !!! this LCD module was used in old Nokia 5110/3310 cell phones. Now its been widely used by hobbyists for graphics, text etc.

Nokia 5110 LCD Display Module is a low-cost monochrome LCD module comprised of 84x48 pixels that can be used to display rich graphic and text content. Though it"s an industrial module, this LCD display is extremely easy to use. This module is are vision that accepts 3-5V input. So no extra level shifter is needed. To have full control, you just need 5 pins. And as a classic display module among opensource communities, there are handful related tutorials available over the Internet. So there is no need to panic even if you just got your foot in the door.

Though it’s an industrial module, this LCD display is extremely easy to use. The Nokia 5110 is a basic graphic LCD screen for lots of applications. It was originally intended for as a cell phone screen.

This Nokia 5110 LCD Display Module is mounted on an easy to solder PCB. The Nokia 5110 LCD Module uses a Philips PCD8544 LCD driver, which is designed for mobile phones.

It uses the PCD8544 controller, which is the same used in the Nokia 3310 LCD. The PCD8544 is a low power CMOS LCD controller/driver, designed to drive a graphic display of 48 rows and 84 columns. All necessary functions for the display are provided in a single chip, including on-chip generation of LCD supply and bias voltages, resulting in a minimum of external components and low power consumption. The PCD8544 interfaces to microcontrollers through a serial bus interface.

Can use the conductive glue to connect the module to the printed board, without cables. The metal hooks on the module can fix the module on the printed board, which is very easy to install and replace.

Many devices that can be used with an Arduino, require a power supply of 3.3V. This is also the case with the Nokia 5110. The best way to deal with 5V devices is to take an Arduino Pro, which can run on 5V.

Thanks to the internal clamp of the PCD8544 we can use a very simple level shifter. Four current limiting resistors of 10kΩ can do the job. When an LCD control line is high, the current through the 10kΩ resistor is just 40uA, so this is harmless. Note that we can’t read back from the LCD with this circuit.

Because VDD max = 7V, the PCD8544 controller can handle 5 to 7V, but the Nokia 5110 LCD works best at 5V. The four resistors of 10kΩ avoid streaks on the LCD display. (at 7V the screen becomes somewhat black when tested)

Here I’ve added a the 5110 LCD to a logger recording data from a BME280 & Tipping Bucket Rain gauge. If the BME  survives in our field environment, this will become a standard configuration for our climate stations. I’m not holding my breath though, as we’ve tested half a dozen RH sensors so far and none of them have gone the distance in high humidity environments that occasionally go condensing.

This year I want to tackle some projects that need live data out, so I’ve been sifting through the many display options available for Arduino. Unlike flashier projects, my goal was to find one that I could add to existing logger builds without sacrificing too much of the multi-year lifespan I had worked so hard to achieve. The low power winner by a fair margin was the Nokia 5110 Liquid-crystal Display  which you can pick up for around $2 from the usual sources. With the back-light off these displays pull between 100-400 μA, depending on the number of pixels turned on.

This screen’s been around for a very long time, so there’s are a huge number of easy to use, highly functional libraries for Arduino. But they tend to focus on things like speed or endless font options which are not important for most data logging applications. And these libs assume your project can afford to lose up to ⅓ of the available program & variable memory just driving the display. Most also require the hardware SPI lines, but our project needs those for SD cards, which are finicky enough without some pokey LCD gumming up the works: the 5110 maxes out at 4mbps, and this slows the bus significantly .

To make this limited large-number font I first composed a black & white bitmap for each number with a graphic editor, and then loaded that .bmp file into the LCD assistant program as described in this instructables tutorial.  I started with a bitmap that was 11 pixels wide, by 16 pixels high (though you can use any arbitrary size you want – just remember to leave the blank spacer row at the bottom) and for this two-pass ‘sliced-letters’ method I set vertical & little endian encoding in LCD assistant. I then put the top 11 bytes in the Big11x16numberTops[] array & the lower 11 bytes for each number in the Big11x16numberBottoms[] array.

The stuff I posted on Github assumes you are using a standard 6-pin arrangement shown in most Nokia 5110 hookup guides you will find on the web. But once I had that wrangled, I realized that it would be possible to reduce the number pins needed to drive the display.  You will have to tweak that default example by commenting out the RS & CS commands if you implement the pin-power changes I’m suggesting here…

My tests so far have shown reliable operation of pin-powered 5110’s through more than 8000 ‘long-sleep’ power cycles. In applications where I want to display data on the screen on for long periods of time,  I still depower the screen during the new sensor readings. This lets me know when the logger is capturing data and forces a periodic re-synch with the bus. I don’t know how long these displays would run continuously without that step, but I’m sure the coms would eventually go AWOL without some kind of regular reset.

No screen is much use on our project unless it can withstand some bumping around in the real world, and ideally we want one that is dive-able. For several years my go-to solution has been to pot surface mounted LED’s and sensors in Loctite E30CL. I like this epoxy because the slow cure usually sets clear because bubbles have time to rise to the surface without a vacuum treatment. My first attempts looked great the night of the pour, but I got a nasty surprise the following morning. You see I usually mount sensors in small ½-1 inch wells, but the 5110 required a ring more than 2” in diameter. The contraction of the epoxy in this 10mm deep well caused pressure marks on the edges of the screen, and a significant brown spot in the center of the display where the text became inverted.

The next attempt was much more successful, as I built up the epoxy a few mm at a time like the layers of an onion. As each layer hardened, it protected the screen from the contraction of the subsequent layers above.  The trick was to bring the first pour to the base of the pcb, and the second pour to “just barely” cover the surface of the screen. The epoxy penetrates about 1/3 of the way into the display housing but this does not interfere with readability as those edges are invisible under natural lighting conditions. That epoxy is actually under the LCD, in the air gap between the transparent glass LCD sandwich and the white reflector plastic which holds the thin LCD in place between the metal rim and the PCB.  I’ll try future pours at different angles to see if that lets the space under the LCD fill completely. Looking at the epoxy penetration, it’s clear that the black edges in pour #1 were places where the LCD was compressed on both sides, and the brown discoloration was from pressure on top with no support below.

After several builds using the this LCD screen I finally got around to (not counting EEprom.h) And that’s with three copies of the output functions because of the simple 2-pass method I’m using to display the large numbers.  A small price to pay for live data output on our loggers!

According to the datasheet for the LCD controller it should run happily from 5V supply. The controller accepts logic levels up to Vdd, so I see no problem with that either. I also never had any issues with a Nokia 3310 display, which uses the same controller, operating at 5V.
