lcd display 16x2 datasheet brands

FSTN Gray background, SPI Interface, RGB Edge-lit LED backlight, bottom (or 6:00) viewing angle, Transflective polarizer, 5-Volt LCD, 5-Volt LED, RoHS Compliant. This display has a wide temperature range: -20° Celcius to +70° Celcius which equates to (-4° Fahrenheit to +158° Fahrenheit).

FSTN (Film-compensated Super-twisted Nematic) provides a sharper contrast than STN by adding a film. The cost is approximately 5% higher than STN. FSTN works great for indoor and outdoor applications and is mainly used in graphic displays and higher end products. The Transflective polarizer is a mixture of Reflective and Transmissive. It provides the ability to read the LCD with or without the backlight on. It will work for all lighting conditions from dark with backlight to direct sunlight which makes it the most common choice. There is no cost difference between Transflective, Transmissive and Reflective.

Thanks loophole! I got the display working fine using this link that link that was mentioned, http://arduino.cc/en/Tutorial/LiquidCrystal, but it was dim since the backlight was not working. After reading loophole"s comment and looking at datafile I applied 4.2V pin 15 and grounded pin 16, and all was GREAT!

I am using the exact components and have followed the exact pin configurations for the past 2 weeks, connecting then reconnecting, I have also tried different FTDI cables for uploading onto the Arduino pro mini. BUT have had no success, PLEASE help me as it is a basic issue I am sure but cannot find the solution, My 16*2 LCD lights up and also when I upload a program the arduino page reads that it has successfully uploaded (Done Uploading).

We"ve had customers order face plates through Ponoko for these LCDs and be pretty happy with it. Check around on the comments on other products and on the forum. You"ll probably find a lot of different examples of mounting solutions.

can this run in 8bit mode? I"m trying so hard to just wire up the 8 data lines and manually send the bits required for certain symbols. But it"s either stuck in 4bit mode, or I"m completely lost. My program is simple and I KNOW that it is sending the 1"s and 0"s down the appropriate lines but I can"t get a response at all. And I can succesfully apply the example code for liquid crystal. In class we just banged some bits into those old lcd"s and got the expected response... Is this one more advanced or something? Thanks, I really appreciate any help.

No matter what line I set the cursor at using lcd.setCursor(0,0), or lcd.setCursor(0,1), it will print everything on line 0. I"ve used the same LCD, different size before and never had this issue.

You should make the LCD"s connection pins on the bottom, like on the RGB backlit LCD"s (https://www.sparkfun.com/products/10862). I like standing them straight up and down on breadboards. If I tried that with this one, it would be upside down.

I"m having a problem with this lcd, I can"d print custom caracters, I tried the code that this site http://icontexto.com/charactercreator/ gives you when you create a custom char, tried some other examples, but nothing, I always get just two vertical bars on the second and fourth columns.

I love this little LCD! It works great. However, I"m having a wicked hard time finding hardware (i.e. self-clinching PEM stud) that I can use to mount this. The 2.5mm mounting holes are pretty small. I"m trying hard not to use glues.

I"m also having trouble with LCD. I hooked up at 10kOhm pot, but when I upload the code it just gives me random pixels and characters. Is my Atmega on my Arduino Uno shot?

Also no external resistor is needed for the backlight; just like almost all other 5v character LCDs this one has a series resistor right on the board. Mine is 130 ohms.

I was able to achieve much better contrast by applying a slightly negative voltage on the Vo pin (3). Minus 200 mV did the trick. I seem to remember that LCD"s used to have a negative output for just this reason. I don"t know what the rating of this pin is, so proceed with caution.

I made it work by using the same schematic featured in the LiquidCrystal Arduino library page, except LCD pin 6 is hooked to a digital PWM instead of a potentiometer for controlling contrast.

Pretty cool little LCD. I had some problems initially with the 4bit LCD library, but after finding that the standard LiquidCrystal library supports 4-bit data lines it worked great.

The one thing that threw me off was that the standard (not extended) datasheet mentions that the backlight (BKL) can be driven by pins 1,2 or 15,16 -- however I found that I needed to apply 4.2v to pins 15,16 before the backlight would work. Easy fix, just misleading on the datasheet.

I"m very impressed. I followed the connections from the data sheet and set them up the same way the LiquidCrystal "Hello World" example sketch calls for, and the display worked perfectly with my Arduino Duemilanove. It does take some playing with the contrast potentiometer, but I quickly found the perfect setting. The display is sharp, clear, and cool white letters on a black background.

Have you wired in the backlight? That tutorial doesn"t include wiring pins 15 and 16 on the lcd. I have hooked the backlight up to a pwm output so that I can turn it on and off via sketch.

I am also ahving this same problem. The LCD was great and easy to set up, but the brightness is really really poor. I installed a pot and all, but no dice.

Has anyone got this working with the LiquidCrystal or LCD4bit library? I am having quite a bit of trouble getting it to work reliably and am at the point where I am going to try and code my own library for it.

I"m also having heaps of trouble. I can sometimes get it to display text, maybe once out of every 30 attempts. And IF it decides to display anything it ends up garbling the message and locking up, not displaying the other strings in the sequence. Is this the LCD, my Arduino or the library? I tried using LCD4bit and a modified LiquidCrystal and they all yield the same, frustrating results.

Great little lcd, for basic output, debugging etc. Very easy to interface, and looks very slick! If you need a basic no frills LCD, this is a good buy.

The easiest way would be to stick a transistor inline with the power lead of the lcd and turn it off just before the cpu goes into the low power state.

This product worked great. I wrote a tutorial about manually writing data to the display using dips switches and push buttons. http://volatileinterface.com/2015/05/30/using-a-hd44780-lcd-display-in-4-bit-mode/

Completely useless, I have no idea what happened but when I wire it up according to the tutorial on arduinos site for the Hello World! LCD program, nothing but the backlight comes on. Also the pins are flipped from where they are in the schematic. Total cluster fuck of a product.

I just realized I forgot the bridge connections over the cnter of the breadboard to actually connect the data lines to the LCD. It works now I think I need to adjust the contrast or something. The text on the display is more visible when looking at the display from an angle.

I just bought this and thought it had the HD44780 chipset but now I started looking at the datasheet for the pin interface descriptions and I realize that it has the KS006U chipset? Is the datasheet wrong or is the sparkfun description wrong? Or maybe they are basically the same chipset? I"m confused right now. Do I need to buy a different LCD?

HD44780 is more a standard that a chipset at this point. there are tons of different chipsets that use the same protocols. like how people say "allen wrench" instend of saying hex key. HD44780 is the LCD equivilent of X86 instruction set. the cool think is you can lean how to use the 16x2, and then use the same code on everything from 8x1 to 40x4 displays.

You can simulate data on each pin of the HD44780 compatible LCD and see how it works, or if you are more advanced you can write directly your own scripts in the web browser to control the LCD, same as you would use them in the MCU code

Is there a flat cable assembly available for these? I"m OK using the 0.1" headers, but the electronics I need to hook up requires a cable interconnect. And I"d like it so that I can replace the LCD without desoldering it.

I?m considering using this in a battery powered device that will experience long periods of inactivity. During the inactive periods all system components will enter a low power stand-by or sleep state. This display does not appear to have a low power (uA) state.

This is a very late response, but anybody in this situation can simply connect the LCD in series with a MOSFET. YOu can then switch the LCD on and off from a microcontroller. Remember to leave all the microcontroller outputs floating because power can still flow into the LCD if you keep these in certain states.

16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. But the most used one is the 16*2 LCD, hence we are using it here.

All the above mentioned LCD display will have 16 Pins and the programming approach is also the same and hence the choice is left to you. Below is the Pinout and Pin Description of 16x2 LCD Module:

These black circles consist of an interface IC and its associated components to help us use this LCD with the MCU. Because our LCD is a 16*2 Dot matrix LCD and so it will have (16*2=32) 32 characters in total and each character will be made of 5*8 Pixel Dots.  A Single character with all its Pixels enabled is shown in the below picture.

So Now, we know that each character has (5*8=40) 40 Pixels and for 32 Characters we will have (32*40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels.

It will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780 is used, which is mounted on LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen.

The LCD can work in two different modes, namely the 4-bit mode and the 8-bit mode. In 4 bit mode we send the data nibble by nibble, first upper nibble and then lower nibble. For those of you who don’t know what a nibble is: a nibble is a group of four bits, so the lower four bits (D0-D3) of a byte form the lower nibble while the upper four bits (D4-D7) of a byte form the higher nibble. This enables us to send 8 bit data.

As said, the LCD itself consists of an Interface IC. The MCU can either read or write to this interface IC. Most of the times we will be just writing to the IC, since reading will make it more complex and such scenarios are very rare. Information like position of cursor, status completion interrupts etc. can be read if required, but it is out of the scope of this tutorial.

The Interface IC present in most of the LCD is HD44780U,in order to program our LCD we should learn the complete datasheet of the IC. The datasheet is given here.

There are some preset commands instructions in LCD, which we need to send to LCD through some microcontroller. Some important command instructions are given below:

This is a basic 16 character by 2 line display. Black text on Green background. Interface code is freely available. You will need ~11 general I/O pins to interface to this LCD screen. Using the very common Sumsang KS0066 parallel interface chipset which is equivalent of Hitachi HD44780. Includes LED backlight.

ERM1602DNS-1 is big 16 characters wide,2 rows character lcd module,SPLC780C controller (Industry-standard HD44780 compatible controller),6800 4/8-bit parallel interface,single led backlight with white color included can be dimmed easily with a resistor or PWM,stn-lcd positive,white text on the black color,wide operating temperature range,rohs compliant,built in character set supports English/Japanese text, see the SPLC780C datasheet for the full character set. It"s optional for pin header connection,5V or 3.3V power supply and I2C adapter board for arduino.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!".For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

We come across Liquid Crystal Display (LCD) displays everywhere around us. Computers, calculators, television sets, mobile phones, and digital watches use some kind of display to display the time.

An LCD screen is an electronic display module that uses liquid crystal to produce a visible image. The 16×2 LCD display is a very basic module commonly used in DIYs and circuits. The 16×2 translates a display of 16 characters per line in 2 such lines. In this LCD, each character is displayed in a 5×7 pixel matrix.

Contrast adjustment; the best way is to use a variable resistor such as a potentiometer. The output of the potentiometer is connected to this pin. Rotate the potentiometer knob forward and backward to adjust the LCD contrast.

A 16X2 LCD has two registers, namely, command and data. The register select is used to switch from one register to other. RS=0 for the command register, whereas RS=1 for the data register.

Command Register: The command register stores the command instructions given to the LCD. A command is an instruction given to an LCD to do a predefined task. Examples like:

Data Register: The data register stores the data to be displayed on the LCD. The data is the ASCII value of the character to be displayed on the LCD. When we send data to LCD, it goes to the data register and is processed there. When RS=1, the data register is selected.

Generating custom characters on LCD is not very hard. It requires knowledge about the custom-generated random access memory (CG-RAM) of the LCD and the LCD chip controller. Most LCDs contain a Hitachi HD4478 controller.

CG-RAM address starts from 0x40 (Hexadecimal) or 64 in decimal. We can generate custom characters at these addresses. Once we generate our characters at these addresses, we can print them by just sending commands to the LCD. Character addresses and printing commands are below.

LCD modules are very important in many Arduino-based embedded system designs to improve the user interface of the system. Interfacing with Arduino gives the programmer more freedom to customize the code easily. Any cost-effective Arduino board, a 16X2 character LCD display, jumper wires, and a breadboard are sufficient enough to build the circuit. The interfacing of Arduino to LCD display is below.

The combination of an LCD and Arduino yields several projects, the most simple one being LCD to display the LED brightness. All we need for this circuit is an LCD, Arduino, breadboard, a resistor, potentiometer, LED, and some jumper cables. The circuit connections are below.

16x2 LCD modules are very commonly used in most embedded projects, the reason being its cheap price, availability, programmer friendly and available educational resources.

16×2 LCD is named so because; it has 16 Columns and 2 Rows. There are a lot of combinations available like, 8×1, 8×2, 10×2, 16×1, etc. but the most used one is the 16×2 LCD. So, it will have (16×2=32) 32 characters in total and each character will be made of 5×8 Pixel Dots. A Single character with all its Pixels is shown in the below picture.

Now, we know that each character has (5×8=40) 40 Pixels and for 32 Characters we will have (32×40) 1280 Pixels. Further, the LCD should also be instructed about the Position of the Pixels. Hence it will be a hectic task to handle everything with the help of MCU, hence an Interface IC like HD44780is used, which is mounted on the backside of the LCD Module itself. The function of this IC is to get the Commands and Data from the MCU and process them to display meaningful information onto our LCD Screen. You can learn how to interface an LCD using the above mentioned links. If you are an advanced programmer and would like to create your own library for interfacing your Microcontroller with this LCD module then you have to understand the HD44780 IC working and commands which can be found its datasheet.
