i2c 1602 lcd module datasheet brands

An LCD display that can display a max of 16x2 charactors. with the help of the I2C bus convertor and related libraried, you can easily use this module with just 2 wires.

This 16 character by 2 line display has a very clear and high contrast white text upon a blue background/backlight. It also includes a serial I2C/IIC adaptor board pre-soldered to the back of the LCD. This means it can be controlled with just 2 I2C serial data pins (SDA & SCL) and so requires far less digital IO pins when controlled from a microcontroller. In total the module only requires 4 wires including 5V power and GND. Contrast adjustment is also provided by the daughter board via a potentiometer. If you plan to use this with an Arduino board you can download a compatible library and example sketch from our support forum

These modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have check the black I2C adaptor board on the underside of the module. If there a 3 sets of pads labelled A0, A1, & A2 then the default address will be 0x3F. If there are no pads the default address will be 0x27.

If pressure is applied to the I2C daughter board it is possible for it to bend and come contact with the LCD module. Please ensure when the LCD is installed in your application that no external object is applying pressure to the back of the module.

This LCD module uses the I2C protocol, meaning you only need 4 wires instead of using 16 to integrate this with your Arduino and it is 5V supply. It can display up to 2 lines of 16 characters. It supports Super Twisted Nematic (STN) positive transflective mode of display. The backlight color of this module is yellow, and the text is black. We have the blue blacklight version here.

Working on an embedded system requires you to deal with a reliable output device to exhibit the information that you need. Well, the issue is addressed with the introduction of the 1602 12C LCD Display Module that helps users see the data and information displayed on the screen. Though it comes with different background colors, we are considering a unit with a yellow-colored background.

Further, the 2X16 Display Module with a yellow backlight integrates a 12C interface to exchange information with the host microcontroller.It is a low-cost display unit that can be used on projects needing the presentation of data, text or ASCII characters of multiple types. The 5VDC device can be found on the 12C bus (0x27/0x3F).

It is a great IIC/12C/SPI/TWI interface that is able to release data display via 2 wires. With a maximum of 16x2 characters, the LCD display panel is efficient to impart the required data and information to users. It allows you to monitor your microcontroller’s every move by checking the process status, information display, and alphanumeric output. Interestingly, it permits users to get the alphanumeric display interfaced with any host controller, including PIC Series, 8051 derivatives, ARM/AVR series of controllers. One can also use development boards (Raspberry/Arduino)for the same purpose.

The 12C 16x2 LCD Display Module (Yellow) integrates an inbuilt PCF8574 12C chip. It can convert 12C serial data into parallel data and they are supplied with a default 12C address of either 0x3F or 0x27.Users can check the black 12C adaptor board (underside of the module) to determine the version they’re using. It combines a contrast adjustment pot down under the display.

LCD I2C 1602 Display Module Blue-  Here"s a cherished item in the Arduino prototyping craft. The LCD I2C 1602 Display Module is an LCD that uses the I2C protocol to communicate with microcontrollers. With this, you only need 4 connections to work with the device: Power, Ground, SDA, and SDL. Furthermore, it can also display a max of 16x2 characters. Its ease of use and efficiency has proven itself a great tool for engineers and makers alike.

A display could be the most sought-after thing in case you want to integrate some visual outputs into your Arduino projects. The LCD 12C 1602 Display can be a reliable solution if you prefer a small-sized panel. It comes to serve you with a simple and cost-effective solution in the context of Arduino units. The display allows you to add a 16x2 White on RGB Liquid Crystal Display.

Furthermore, the LCD display features a good blue backlight reflection that ensures great integrations for Arduino-based projects. The module houses 16 characters by a 2-line display to generate clearer and high-contrast text with blue lighting in the background. Arduino LCD Display projects will run short of pin integrations, especially when it collaborates with Arduino UNO.

At the same time, wire soldering and connection establishment also tend to be complicated affairs. The 12C 1602 LCD Display owns a 12C communication interface.It signifies the requirement of only 4 pins for the LCD unit to get it in perfect working condition. It includes GND, SDA, VCC, and SCL. Ultimately, it comes to saving at least 4 pins (analog/digital) on the Arduino projects. Since connectors are standard XH2.54, it allows you to connect directly with the jumper wire.

The key consideration that can also captivate your attention is the drawback derived from the LCD 1602 Parallel Display. As per this attribution, a user is likely to waste about 8 pins on the Arduino projects to get the display to work. What makes this product fascinating is that the 12C adapter is soldered right onto the pins on the display unit. Thereby, you require connecting only 12C pins to capture a good source of library.

Furthermore, the wiring event is going to be super easy if your board has already integrated the 12C adaptor. You only need to hook up 4 pins, including GND and VCC. You’ll have to use a 5V pin since the LCD Display unit works with 5 volts.

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.

If you’ve ever tried to connect an LCD display to an Arduino, you might have noticed that it consumes a lot of pins on the Arduino. Even in 4-bit mode, the Arduino still requires a total of seven connections – which is half of the Arduino’s available digital I/O pins.

The solution is to use an I2C LCD display. It consumes only two I/O pins that are not even part of the set of digital I/O pins and can be shared with other I2C devices as well.

True to their name, these LCDs are ideal for displaying only text/characters. A 16×2 character LCD, for example, has an LED backlight and can display 32 ASCII characters in two rows of 16 characters each.

At the heart of the adapter is an 8-bit I/O expander chip – PCF8574. This chip converts the I2C data from an Arduino into the parallel data required for an LCD display.

If you are using multiple devices on the same I2C bus, you may need to set a different I2C address for the LCD adapter so that it does not conflict with another I2C device.

An important point here is that several companies manufacture the same PCF8574 chip, Texas Instruments and NXP Semiconductors, to name a few. And the I2C address of your LCD depends on the chip manufacturer.

According to the Texas Instruments’ datasheet, the three address selection bits (A0, A1 and A2) are placed at the end of the 7-bit I2C address register.

According to the NXP Semiconductors’ datasheet, the three address selection bits (A0, A1 and A2) are also placed at the end of the 7-bit I2C address register. But the other bits in the address register are different.

So your LCD probably has a default I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it.

Connecting an I2C LCD is much easier than connecting a standard LCD. You only need to connect 4 pins instead of 12. Start by connecting the VCC pin to the 5V output on the Arduino and GND to ground.

Now we are left with the pins which are used for I2C communication. Note that each Arduino board has different I2C pins that must be connected accordingly. On Arduino boards with the R3 layout, the SDA (data line) and SCL (clock line) are on the pin headers close to the AREF pin. They are also known as A5 (SCL) and A4 (SDA).

After wiring up the LCD you’ll need to adjust the contrast of the display. On the I2C module you will find a potentiometer that you can rotate with a small screwdriver.

Plug in the Arduino’s USB connector to power the LCD. You will see the backlight lit up. Now as you turn the knob on the potentiometer, you will start to see the first row of rectangles. If that happens, Congratulations! Your LCD is working fine.

To drive an I2C LCD you must first install a library called LiquidCrystal_I2C. This library is an enhanced version of the LiquidCrystal library that comes with your Arduino IDE.

Filter your search by typing ‘liquidcrystal‘. There should be some entries. Look for the LiquidCrystal I2C library by Frank de Brabander. Click on that entry, and then select Install.

The I2C address of your LCD depends on the manufacturer, as mentioned earlier. If your LCD has a Texas Instruments’ PCF8574 chip, its default I2C address is 0x27Hex. If your LCD has NXP Semiconductors’ PCF8574 chip, its default I2C address is 0x3FHex.

So your LCD probably has I2C address 0x27Hex or 0x3FHex. However it is recommended that you find out the actual I2C address of the LCD before using it. Luckily there’s an easy way to do this, thanks to the Nick Gammon.

But, before you proceed to upload the sketch, you need to make a small change to make it work for you. You must pass the I2C address of your LCD and the dimensions of the display to the constructor of the LiquidCrystal_I2C class. If you are using a 16×2 character LCD, pass the 16 and 2; If you’re using a 20×4 LCD, pass 20 and 4. You got the point!

First of all an object of LiquidCrystal_I2C class is created. This object takes three parameters LiquidCrystal_I2C(address, columns, rows). This is where you need to enter the address you found earlier, and the dimensions of the display.

In ‘setup’ we call three functions. The first function is init(). It initializes the LCD object. The second function is clear(). This clears the LCD screen and moves the cursor to the top left corner. And third, the backlight() function turns on the LCD backlight.

After that we set the cursor position to the third column of the first row by calling the function lcd.setCursor(2, 0). The cursor position specifies the location where you want the new text to be displayed on the LCD. The upper left corner is assumed to be col=0, row=0.

There are some useful functions you can use with LiquidCrystal_I2C objects. Some of them are listed below:lcd.home() function is used to position the cursor in the upper-left of the LCD without clearing the display.

lcd.scrollDisplayRight() function scrolls the contents of the display one space to the right. If you want the text to scroll continuously, you have to use this function inside a for loop.

lcd.scrollDisplayLeft() function scrolls the contents of the display one space to the left. Similar to above function, use this inside a for loop for continuous scrolling.

If you find the characters on the display dull and boring, you can create your own custom characters (glyphs) and symbols for your LCD. They are extremely useful when you want to display a character that is not part of the standard ASCII character set.

CGROM is used to store all permanent fonts that are displayed using their ASCII codes. For example, if we send 0x41 to the LCD, the letter ‘A’ will be printed on the display.

CGRAM is another memory used to store user defined characters. This RAM is limited to 64 bytes. For a 5×8 pixel based LCD, only 8 user-defined characters can be stored in CGRAM. And for 5×10 pixel based LCD only 4 user-defined characters can be stored.

After the library is included and the LCD object is created, custom character arrays are defined. The array consists of 8 bytes, each byte representing a row of a 5×8 LED matrix. In this sketch, eight custom characters have been created.

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.
