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.

Now you must have guessed it, Yes 8-bit mode is faster and flawless than 4-bit mode. But the major drawback is that it needs 8 data lines connected to the microcontroller. This will make us run out of I/O pins on our MCU, so 4-bit mode is widely used. No control pins are used to set these modes. It"s just the way of programming that change.

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:

16×2 LCD is a basic 16 character by 2 line display Yellow/Green Backlight. Utilizes the extremely most common HD44780 parallel interface chipset (datasheet). Even more, it has JHD162A Compatible Pinout Diagram, and Command Interface code is freely available. Finally, You will need 7 general I/O pins (If used in 4-bit Mode) to interface to this LCD screen. it also includes an LED back-light.

Features of 16×2 Display LCD:Commonly Used in Student Project, College, copiers, fax machines, laser printers, industrial test equipment, networking equipment such as routers and storage devices

The 16x2 is the most commonly used LCD display module. It can display 16 characters in a column for 2 rows thus a total of 32 characters. The characters can either be number, alphabets or symbol. It is also possible to create your own custom character and display it if required. The LCD has the HD44780U display driver IC which is responsible for displaying characters on the LCD

This 16x2 LCD display has a blue background and back light which makes it unique and more visible than the commonly used green color. If you need the green backlight you can use this Green Backlight LCD. The required supply voltage is from 4.7V to 5.3V and the LCD can operate either in 8-bit mode or in 4-bit mode allowing you to save more GPIO pins on the controller side. The current consumption is about 1mA without the back light.

The 16x2 LCD pinout diagram is shown below. As you can see the module has (from right) two power pins Vss and Vcc to power the LCD. Typically Vss should be connected to ground and Vcc to 5V, but the LCD can also operate from voltage between 4.7V to 5.3V. Next, we have the control pins namely Contrast (VEE), Register Select (RS), Read/Write (R/W) and Enable (E). The Contrast pin is used to set the contrast (visibility) of the characters, normally it is connected to a 10k potentiometer so that the contrast can be adjusted. The Read/Write pin will be grounded in most cases because we will only be writing characters to the LCD and not read anything from it. The Register Select (RS) and Enable pin (E) pin are the control pins of the LCD and will be connected to the digital pins GPIO pins of the microcontroller. These pins are used to instruct the LCD where place a character when to clear it etc.

From DB0 to DB7 we have our eight Data Pins which are used to send information about the characters that have to be displayed on the LCD. The LCD can operate in two different modes, in the 4-bit Modeonly pins DB4 to DB7 will be used and the pins DB0 to DB3 will be left idle. In 8-bit Mode, all the eight-pin DB0 to DB7 will be used. Most commonly the 4-bit mode is preferred since it uses only 4 Data pins and thus reduces complexity and GPIO pin requirement on the microcontroller.Finally, we have the LED+ and LED- pins which are used to power the backlight LED inside our Display module. Normally the LED+ pin is connected to 5V power through a 100 ohm current limiting resistor and the LED- pin is connected to Ground.

The 16x2 Alphanumeric LCD Display Module is equally popular among hobbyists and professionals for its affordable price and easy to use nature. As the name suggests the 16x2 Alphanumeric LCD can show 16 Columns and 2 Rows therefore a total of (16x2) 32 characters can be displayed. Each character can either be an alphabet or number or even a custom character. This particular LCD gas a green backlight, you can also get a Blue Backlight LCD to make your projects stand our and visually appealing, apart from the backlight color both the LCD have the same specifications hence they can share the same circuit and code. If your projects require more characters to be displayed you can check the 20x4 Graphical LCD which has 20 Columns and 4 Rows and hence can display up to 80 characters.

This is just a complementary answer for people facing this question for the first time (beginners or even non-beginners), like I did a few months ago when received a batch of no-name LCD modules clones of the JHD162A with an incorrect datasheet. This answer only apply to LCD modules with a LED backlight (using a single LED or an array of LEDs) which are the most popular.

If you have the datasheet, it should contain the information somewhere, you just need to calculate the current limiter resistor value using the suggested LED forward current and supply voltage minus the LED forward voltage.

If you don"t have the datasheet, check the back of the LCD. Usually you can find easily if there is a resistor in series with the A (or even the K) pin. The following images show how some modules which already have a limiting resistor. Just be sure it is really a resistor and not a jumper (a zero ohm "resistor").

If you are designing a PCB and you are not sure if the provisioned LCD modules will have already a resistor, just add the space for a resistor in your circuit; so later on, during production, you can use a resistor or a jumper. (Of course that kind of thing should be known in advance, but sometimes is not always possible, or the requirements may state that your circuit it should work with any LCD module).

In this image a LCD 16x2 character module has a 100 ohm resistor (R8) in series with the A pin (pin 15) trace. The value was verified measuring from pin 15 to the A pad (in the left edge) soldered to the backlight.

In this image, a JDH204A (JHD629) LCD 20x4 character module has a combination of jumpers and resistors to select what pins are for the cathode (K) and anode (A) (the table in the silkscreen describe the configuration options). In this case R9 and R11 are using jumpers, meaning pin 15 is for the anode and 16 is for the cathode of the backlight, and the R12 and R13 are the limiting resistors (they are in parallel, in this case both are 68 ohms, providing 34 ohms). The value was verified by measuring the resistance between pin 15 and the A1 pad (at the left edge) soldered to the backlight.

In all modules I have used over the years, the backlight supply pins (A and K) are completely independents of the LCD and controller circuit, so you may use a different supply rail with a different voltage than the rest of the circuit. (Just note that this has just been my experience with the original JHD modules and some clones, but this may not apply to other brands).

I am currently using msp430g2553 which came along the launchpad. I am facing problems regarding interfacing the LCD module. I am currently using JHD 162A 16x2.

This is all the code for the MSP430 LCD driver. A simple flow is demonstrated in the main() function. This code should be copy-paste runnable on the value line part plugged into the shipping launchpad. If things aren"t working it might be because your LCD module is slower. Try extending the __delay_cycles, first in the Initialization routine. If that doesn"t fix it extend the delay time in the pulse module as well.
