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.

Cheap character LCDs based on the HD44780 chipset come in a variety of sizes: 2x16, 4x20, etc. These displays have two standard interface modes, 4bit and 8bit parallel. 8bit requires a total of 11 data lines, 4bit requires 7 (6 for write-only). Some LCDs support an additional serial data mode, like the VFD Ian covered at Hack a Day.

HD44780 LCDs are generally 5volt parts with a separate supply for the back light. The Bus Pirate only has five 5volt tolerant I/O pins, so we made a small adapter board with enough pins to control the LCD. The Bus Pirate controls the adapter board through its LCD interface library.

In this article we outline an I2C adapter board for HD44780-based LCDs. We demonstrate it with a Bus Pirate universal serial interface. The Bus Pirate source code for the I2C-based HD44780 interface library is public domain, so it"s free to adapt to your own projects.

Full size circuit image [PNG]. The circuit and PCB were designed with the free version of Cadsoft Eagle. The design files can be downloaded from the Bus Pirate SVN. Before using the adapter board,be sure to verify the datasheet for your LCD against the adapter pinout. Not all LCDs are the same.

The PCF8574 works from 2.5 to 5volts. The I/O pins operate at the supply voltage, so if we feed it 5volts it interfaces the LCD at 5volts. C1 (0.1uF) decouples the IC from fluctuations in the power supply.

The adapter board communicates with an HD44780-based character LCD in 4bit parallel interface mode. The 4bit interface pins - RS, RW, EN, and D4-D7 - are connected to seven of the PCF8574 I/O pins. We like to use 0.1" male pin header to connect the adapter to an LCD, you can usually lean the LCD against the pins to create sufficient contact for a quick test.

Most LCDs require 5volts, provide an external power supply through header JP2. We provided a second power supply pin to connect the Bus Pirate"s pull-up resistors.

We designed the adapter for the LCD library of the Bus Pirate universal serial interface, but it"ll work with anything that can speak the I2C protocol. Take a look at the Bus Pirate source code for an example I2C->HD44780 implementation.

Connect the adapter to a power supply sufficient for the LCD, generally 5volts. The I2C connection between the adapter and the Bus Pirate requires pull-up resistors between 2 and 10K. Here"s more information about mixed voltage interfacing with pull-ups, and the Bus Pirate on-board pull-up resistors.

Press "m" in the Bus Pirate terminal and choose the LCD library. It currently it only supports HD44780 character LCDs using the PFC8574 adapter described in the first half of this article (option 1).

This table outlines the single-byte commands that control an HD44780 LCD, here"s a detailed reference. These commands can be entered from the Bus Pirate command line, but we"ve made macros for most of them to save time.

The initialize LCD macro (2) configures the screen for 4bit interface mode, enables cursor display, and sets a few other helpful options. Configure the number of display lines, choose 1 for a single line display, or 2 for all other displays.

HD44780 LCDs need to be reset with a special signal sequence before they can be initialized for 4bit or 8bit interface mode. Macro 1 creates this sequence. Macro 2 includes the reset sequence, so there"s no need to use macro 1 before macro 2.

The write numbers macro fills the LCD with test numbers between 0 and 9. The number after the colon tells the Bus Pirate how many test numbers to write, we"re using a 4x20LCD, so we write 80 numbers to fill it. Notice that the cursor ends at position 0, under the first "0".

The write characters macro fills the LCD with ASCII characters, enter the quantity after the colon. Notice that the fist line continues on the third, the third on the second, and the second on the last. The characters aren"t continuous because character LCDs don"t wrap from one line to the next. We"ll talk a little more about this in step 5.

You could also do any of these operations without the macros, refer to the command table at the beginning of this section. Enter "[0b1" in the Bus Pirate to set the interface to command mode ([) and send the HD44780 clear screen command (0b00000001) without a macro.

After clearing the LCD in step 4, the cursor is positioned at the first block. We could also set it with the macro (4:0), which moves the cursor to the first character.

Writing to the second line is a little more complicated, it actually starts at character 64 on a 4x20 LCD. If you continue writing from the end of line 1 (character 20) then you"ll end up at the beginning of line three! This page has a nice collection of memory maps for most character LCD sizes.

The Bus Pirate and LCD adapter board can read from the LCD. We"ll read the text we wrote to the screen (DDRAM), but you can also read settings and custom character ram (CGRAM) by setting the correct address.

First, we tell the Bus Pirate to send data to the LCD command register ([). Next, we use the set DDRAM address command (0b1xxxxxxx) to set the read pointer to the beginning of the DDRAM (xxxxxxx=0000000).

Finally, tell the Bus Pirate to read from data memory (]), and then read a few bytes (rrrrrrr). We got "HD44780", the text we wrote to the screen in step 5.

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:

The Hitachi HD44780 LCD controller is an alphanumeric dot matrix liquid crystal display (LCD) controller developed by Hitachi in the 1980s. The character set of the controller includes ASCII characters, Japanese Kana characters, and some symbols in two 40 character lines. Using an extension driver, the device can display up to 80 characters.

The Hitachi HD44780 LCD controller is limited to monochrome text displays and is often used in copiers, fax machines, laser printers, industrial test equipment, and networking equipment, such as routers and storage devices.

Compatible LCD screens are manufactured in several standard configurations. Common sizes are one row of eight characters (8×1), and 16×2, 20×2 and 20×4 formats. Larger custom sizes are made with 32, 40 and 80 characters and with 1, 2, 4 or 8 lines. The most commonly manufactured larger configuration is 40×4 characters, which requires two individually addressable HD44780 controllers with expansion chips as a single HD44780 chip can only address up to 80 characters.

Character LCDs may have a backlight, which may be LED, fluorescent, or electroluminescent. The nominal operating voltage for LED backlights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color. Non-LED backlights often require higher voltages.

Character LCDs use a 16-contact interface, commonly using pins or card edge connections on 0.1 inch (2.54 mm) centers. Those without backlights may have only 14 pins, omitting the two pins powering the light. This interface was designed to be easily hooked up to the Intel MCS-51 XRAM interface, using only two address pins, which allowed displaying text on LCD using simple MOVX commands, offering cost effective option for adding text display to devices.

Vee (also V0): This is an analog input, typically connected to a potentiometer. The user must be able to control this voltage independent of all other adjustments, in order to optimise visibility of the display that varies i. a. with temperature and, in some cases, height above the sea level. With a wrong adjustment, the display will seem to malfunction.

R/W: In most applications, reading from the HD44780 is not necessary. In that case, this pin can be permanently connected to ground and no processor pins need to be allocated to control it.

Selecting 4-bit or 8-bit mode requires careful selection of commands. There are two primary considerations. First, with D3–D0 unconnected, these lines will always appear high (binary 1111) to the HD44780 since there are internal pull-up MOSFETs.

The execution times listed in this table are based on an oscillator frequency of 270 kHz. The data sheet indicates that for a resistor of 91 kΩ at VCC=5 V the oscillator can vary between 190 kHz and 350 kHz resulting in wait times of 52.6 µs and 28.6 µs instead of 37 µs. If a display with the recommended 91 kΩ resistor is powered from 3.3 volts the oscillator will run much slower. If the busy bit is not used and instructions are timed by the external circuitry, this should be taken into account.

The original HD44780 character generator ROM contains 208 characters in a 5×8 dot matrix, and 32 characters in a 5×10 dot matrix. More recent compatible chips are available with higher resolution, matched to displays with more pixels.
