Source code for the library used here and its official documentation can be downloaded from the download section of this repository which comes in source and with examples that will get you started. Further, the example sketch has been fully tested with a 4 bit interface as described using Arduino IDE0022.

The hardware configuration described have been tested with an Arduino UNO R3, a 16Г—2 LCD, and an I2C LCD backpack purchased from an eBay seller. Since the display used by the author is a very clear bright вЂњblack on yellowвЂќ type, it is very difficult to get a good catch due to polarization effects. Following is a partial view of authorвЂ™s experiment with the above described code. If you are 100% sure that everything is okay, but you donвЂ™t see any characters on the display, try to adjust the contrast control pot of the backpack and set it a position where the characters are bright and the background does not have dirty boxes behind the characters.

First of all, rename the existing вЂњLiquidCrystalвЂќ library folder in your Arduino libraries folder as a backup, and proceed to the rest of the process.

In short, your backpack is based on PCF8574T and the address connections (A0-A1- A2) are not bridged with solder it will have the slave address 0x27.ДЇor this experiment it is necessary to download and install the вЂњArduino I2C LCDвЂќ library. If your backpack holds a PCF8574AT chip, then the default slave address will change to 0x3F. Note that most backpack modules are centered around PCF8574T (SO16 package of PCF8574 in DIP16 package) with a default slave address of 0x27. The PCF8574 is a silicon CMOS circuit provides general purpose remote I/O expansion (an 8-bit quasi-bidirectional) for most microcontroller families via the two-line bidirectional bus (I2C-bus). In principle, such backpacks are built aorund PCF8574 (from NXP) which is a general purpose bidirectional 8 bit I/O port expander that uses the I2C protocol. Using the LCD backpack, desired data can be displayed on the LCD through the I2C bus. HitachiвЂ™s HD44780 based 16Г—2 character LCD are very cheap and widely available, and is an essential part for any project that displays information. This allows connection to your Arduino (or other microcontroller) using only four channels.

You can use them with LCD modules that have a HD44780 compatible interface with various screen sizes by attaching to the back of the LCD module.

Now a days, it is not necessary to buy an expensive I2C LCD for this task because readymade serial backpack modules for standard LCDs are available at reasonable rates. However, if you use an LCD module with I2C interface, you only need 2 lines to process the display information. To link a standard 16Г—2 LCD directly with the microcontroller, for instance Arduino, you would need atleast 6 I/O pins to talk to the LCD. Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel.
