128 x 64 lcd display arduino brands

Here is one of these guys, in my case a 12864 OLED, SSD1306 based. It was sold to me as a color TFT but it appears to consist of two strips: a 12816 yellow OLED upper strip and a blue OLED lower 12848 strip. That does not matter at all since the device handles like a 12864. This one has 7 pins: GND, VDD, SCK, SDA, RES, DC and CS. Note that most OLED displays are 3.3V devices.

Can you control the backlighting by using PWM on the backlight voltage pin? It"s connected to Vss by default which applies the entire 5v to the pin, but if I can PWM the pin and apply a lower voltage will that dim the display? In essence I"m looking for a way to dim the display using an MCU. Also, when dimmed does it draw less current? (I"m thinking it does, less photons means less work which means less current).

Also, I"m assuming that a lot of current is most likely drawn from that backlight pin so I plan on placing a transistor between the MCU and the LCD which I will drive from the MCU via PWM.

Thanks for sharing your library. I ported it to the XMEGA style and it worked except that I need to add a reset in lcd_init(). I initialized the control port with RESET low, and then I promptly set it high.

The current version of this graphic display (GDM12864H) has a unique feature that I have not seen in any other 128x64 graphic LCD. Its pixels (and pitch) are square (0.39x0.39mm) so your circles appear as circles -- no more ellipses!!!

Thanks for posting. Please explain why you have 2K ohm connected to the V0 and VEE pins? This LCD has built-in DC converter to drive the LCD already?

Someone noted above that the voltage needs to be fairly low (~-4V) to see the darkness of the pixels. If you hook a pot up, be sure to wipe it to both extremes to see if you can atleast see a big black box when the LCD has power, then you know atleast your contrast works and you"re getting power!

I ported the Arduino"s ks0108 library to the MSP430 and have it working. If you"re still interested in the code feel free to ask me. At some time I should put it up for public consumption but it"s not ready yet. With that said I"m still willing to share what I have if people are interested.

astromme - I am currently working on a project with this serial graphic display and I am interested in using the MSP430 could I get a copy of the adapted Arduino ks0108 library? Thank you, this would be greatly appreciated.

You should look on the product page"s documents. There"s links to get it working with an Arduino microcontroller. Also, there is an article on Arduino if you did an online search with example code and a hookup guide => http://playground.arduino.cc/Code/GLCDks0108.

Just remember that if you connect the RES pin to your MCU like I did, you"ll have to add code to this library to bring it high during initialization, or add an extra routine to make use of it.

I"m a little late to the party here, but I"m having some issues with stability. It doesn"t like when I reset my uC (Mega644P). I"m using code derived from summoningdark"s upgraded firmware. When the screen decides to work, it"s great. Sometime if i have a scope on one of the pins it starts just fine. Doesn"t matter which pin. On my scope, I see a lot of noise on the pins. Stuff way below the 5v it"s running on. Any special tricks? Reset operations? Pullup/Pulldown resistors, filter caps?

I recently bought this LCD to use with a Maple Mini board. What Library should I use with it? I found the KS0108 Graphics LCD library on the Arduino page. That seems to be more useful than the LiquidCrystal library which doesn"t seem to work with this 20-pin LCD.

Great screen for playing around with on the Arduino. There"s a full-featured library available with some example sketches to test that your screen is wired correctly. The only downside is that the parallel interface takes up almost all of the pins of the Uno.

The one i ordered off sparkfun nearly a month ago was of the " small fraction of the glcds out there will need a reset pulse" variety? it took me a few days and several hours to realize, i had to waste another pin. The solution was to go into the library and un-comment part of the code as described at the bottom http://www.arduino.cc/playground/Code/GLCDks0108/

I"m looking for a similar specs LCD, but with a white or blue backlight.. I"m planning on adding it next to my motorcycle OEM screen, and being green would quite likely be an ugly mismatch.

Just can"t make mine work. Just received it a while ago and have tried all the suggestions here and nothing. It just starts with all the pixels black and remains like that.

Perhaps the datasheet has changed in the past year, but I see "Logic Supply Voltage", "Operating Voltage", and several others listed as 4.5V Min, 5.0V Typ, 5.5V Max.

I can also confirm after owning one, and attempting to interface with a PIC32MX795F512L that it will not function properly on 3.3V logic. Even removing the PIC from the setup and manipulating the I/O lines by hand, I saw improper behavior with 3.3V and proper behavior with 5V.

This is exactly what I have been looking for to hook up to a Ybox (I just want a neat little gadget to hook up my workshop, nothing too big). But the question is, (and I know this is going to sound noobish, because I am, and have just literally dived into the world of electronics with a lot of information and knowledge already but less than a month"s experience) would it be compatible?

Bought without thinking, I need power from 0ne Li-ion battery. What"s the maximum current this unit takes and is there a simple ways of operating from 3v3 (besides DC-DC converter)?

I wired mine up exactly how it is shown in the pong clock app note. when I try to give it power it starts to draw more then one amp with my power supply at less then 3v. I"ve checked my wires a few times to make sure they match the schematic on the app note.

Make sure that you have a 100 to 330 ohm resister in series with the LCD backlight. Some of the documentation is not clear on this, but the resister must be there or the LED backlight will act like a dead short as soon as the voltage rises above the LED forward bias - usually about 2.0V.

So, stupid question, the LCD screen says it needs 9V to work. Is that supplied by the circuits on the board, or do you need to create a step-up dc converter to change 5V into 9V?

While the microcontroller was running, i had to take the display off my test board, because (stupid as i was) i mounted the V0 pot-meter under it. When i connected it back it was working!

I"m going to have to throw my hat into this with GeodeLX and InkAnkUnk. I can"t get so much as a pixel out of this thing, using Csloser"s AVR code and having checked and rechecked wiring N times. Writing my own library from scratch from the datasheet also results in absolutely nothing. At least the backlight and contrast adjustment via pot works.

On the page Csloser links to, he recommends a pull down resistor. Could anyone comment on the importance of this? Could this be the cause of my one line LCD?

I grabbed the software and loaded it. The backlight works and at first I saw a few lines on the display itself (these faded). When I ran the software from that web page, nothing came out on the display. I played with the contrast potentiometer a little, but I still see nothing. The program is running (I added some Serial output for debugging).

Is it possible that I burned out the controller? Or... is it possible I just got a bad one? Does anyone have experience with these that might be helpful?

There is a very good chance you just haven"t done something right. I had some trouble getting it to work as well, but it was because the code wasn"t doing the right thing. I design and develop my own boards so I have no experience with the Arduino, but if you have a more specific question I can attempt to help you.

I forgot to mention that the LCD voltage, in my experience, should be around -4V for the display to be readable. Close to -5V will turn all of the pixels fully on and above -3V they will be totally transparent. Other units may behave differently but this is how mine works.

I intended to drive this LCD with an ATmega168, which now appears to be an astonishingly bad idea if the uC has only 1K RAM and you need that to drive the LCD. True? Or am I missing something completely obvious to the non-novice? It looks like I need a separate uC (like the DiosPro) to drive the LCD, with the 168 uC controlling the DiosPro via the UART? Happy to take advice....

You don"t have to devote any ATmega168 RAM to the LCD. This component has its own video RAM, one bit per pixel, 512 bytes total. I think you have to write whole bytes at a time (8 pixels), and it doesn"t know how to draw a letter "A" by itself, but the App Note from Kronos Robotics says they have a higher-level Dios library to deal with such operations.

In this project, I will show you how to interface a 128X64 Graphical LCD with Arduino UNO. This particular LCD Module is based ST7920 LCD Controller. So, we will first see a little bit about the Graphical LCD Module and its LCD Controller ST7920.

In the previous Arduino project, I have interfaced a Nokia 5110 LCD Module with Arduino. It is also a graphical LCD which can display some basic bitmap images and graphics. But the issue with Nokia 5110 LCD Module is its resolution.

At 84 x 48 pixels, the Nokia 5110 LCD can be used for implementing a menu-based user interface. Due to its small size, the resulting menu will be limited to 3 or 4 items per page.

If we want a bigger display with more real estate to work with, then the obvious choice is to go for the bigger and better 128×64 Graphical LCD Module.

As a demonstration, after making all the hardware connections, I will display a bitmap image on the Graphical LCD Module. If you are interested in implementing a simple 16×2 Alpha-Numeric LCD with Arduino, then check out this tutorial.

At first glance, the 128×64 Graphical LCD Module seems like a bigger brother to the famous 16×2 LCD or 20×4 LCD Modules, with their similar construction and almost similar pin layout.

But there is a significant difference between those two. 16×2 or 20×4 LCDs are essentially character displays. They can only display alpha-numeric characters and some simple custom characters that are confined to a 5×8 matrix.

By using different combinations of pixels, we can basically display characters of various sizes. But the magic doesn’t end there. You can display images and graphics (small animations) as well. In a 128×64 LCD Module, there are 64 rows and 128 columns.

There are several versions of the Graphical LCD in the market. Even though the usage, application and implementations are almost identical, the main difference lies in the internal LCD Controller used to drive the dot matrix display.

Some of the commonly used LCD Controllers are KS0108, SSD1306, ST7920, SH1106, SSD1322, etc. The pin out of the final LCD Module might vary depending on the LCD Controller used. So, please verify the LCD Controller as well as the pin out before making a purchase.

The Graphical LCD Module I purchased consists of ST7920 Controller. It is manufactured by Sitronix and supports three types of bus interfaces i.e., 8-bit mode, 4-bit mode and Serial interface.

If you have used 16×2 LCD Display earlier, then you might be familiar with both 4-bit as well as 8-bit parallel interfaces. The serial interface is something new and we will explore this option in this project.

As I already mentioned, double-check with the manufacturer about the pinout of the Graphical LCD Module. The following table describes the pinout of the 128×64 LCD Module that I have.

Now that we have seen a little bit about the Graphical LCD and its controller ST7920, let us now proceed with interfacing the 128×64 Graphical LCD with Arduino. I will implement a simple circuit to demonstrate how easy it is to interface the LCD and Arduino using very few external components.

So, connect the RS, RW and E of the LCD to Digital IO pins 10, 11 and 13 of Arduino UNO. Also, in order to select the Serial Interface Mode, the PCB pin must be connected to GND.

The remaining connections are similar to a traditional 16×2 LCD. VCC and GND are connected to 5V and ground of the power supply. VO is connected to the wiper of a 10KΩ POT while the other two terminals of the POT are connected to 5V and GND respectively.

Instead of displaying characters of different fonts (yes, there are libraries using which you can implement various fonts), I will straight away display an image in the form of bitmap. Before writing the code, you need to convert the bitmap image into byte arrays.

I have used the above “The Office” logo. Remember that the resolution of the 128×64 LCD is, well 128×64 pixels. So, the maximum image size should be 128×64. So, using Microsoft Paint, I have brought down the resolution of the above image to 128×64 pixels and also saved it as Monochrome Bitmap Image.

The next step is to convert this bitmap image into bytes array. I have tried several converter tools (both online and offline) but none of them were able to generate a code that is compatible with my setup.

So, I have used the “GIMP” software. You can download GIMP from this link and install it. After installing, you can open the 128×64 Bitmap image in the GIMP software and export it as “X Bitmap Image”.

A .xbm file will be generated. It contains the HEX code for the selected 128×64 Bitmap Image. Open it with any text editor (like Notepad++) and make the following changes. The Array should be a static const unsigned char and append “PROGMEM” after the array name.

Before writing the code, you need to download a special library called “U8g2”. In the Arduino IDE, go to Tools -> Manage Libraries… Search for “u8g2” and install the latest version. It is a complex library and its github page consists of all the necessary documentation.

A simple project for interfacing the 128×64 Graphical LCD with Arduino is implemented here. Instead of displaying plain characters, I have displayed a bitmap image on the LCD to show its capability.

The shield is designed to work with TVI Electronics TGL28G-12864-1 &TGL28G-12864-2 Series 128x64 COG Monochrome Graphic LCDs, Arduino UNO (Duemilanove/Diecimila) as well as Leonardo or Mega. It requires SPI communication. The LCD connection: RESET - D8, A0 - D9, SC - D10, SDI - D11, SCK - D13, and Backlight control - D3. The touch screen connection: XR - D5, YU - A1, XL - A0, YL - D6.

The shield comes fully assembled with 4-wire Resistive touch screen and your choice of LCD. Simply plug it into your Arduino (not included), load up the library, and you"re ready to go!

These LCD displays once were popular and sometimes you may pick one up for a couple of bucks or extract it from some outdated peace of hardware. The typical drawback is the lack of documentation, but if it uses some standard controller there should be a way to drive it with Arduino. I was lucky enough because my display was based on a pretty much common ST7565 controller. The model name was VTM88870B V4.0, which gave not much relevant search results. Mostly Chinese. It took some time to collect necessary information, so I share my results to save your time. And your money. Because You"ll get an Arduino-compatible graphical LCD display for a low price and with minimal soldering skills.However you do it at your own risk, and you are responsible for any harm or damage (or experience :)) that you suffer as a result.

This is how VTM88870B V4.0 LCD display looks like. Output wires and LCD panel are fixed with hot glue, the protective film is somewhat bumpy, but soldering is pretty much neat. And all in all it"s a decent display for its price.

This display features both parallel and serial interfaces. To activate SPI mode, you should solder corresponding jumper as it shown on the following pictures.

The outputs on the LCD board are numbered but not labelled. I figured out which pins are related to SPI interface and depicted them inSchematicssection.Note that you"ll need 3.3V Arduino board to drive this display!

I usedu8g2library since it supports ST7565 controller. If you open any example from u8g2, you"ll see a lot of commented display initializing lines. Since my particular display model is not listed there, I tried all ST7565 displays. If you see mirrored or displaced images, keep on trying. The following initializing line worked for me:U8G2_ST7565_LM6059_1_4W_HW_SPI u8g2(U8G2_R0, /* cs=*/ 10, /* dc=*/ 9, /* reset=*/ 8);// Adafruit ST7565 GLCD

Also, consider number of pins available on your Arduino. It may be that you can drive this LCD with Arduino Uno using serial interface only. (See this link)

You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
