This Arduino library and demo program are located in our github repository.
To run the demo program, click on the menu item File > Examples > I2cCharDisplay.
You will need to restart the Arduino IDE in order to use the library and see the I2cCharDisplayDemo.ino program listed.
Select I2cCharDisplay from the list, and the library files will be ready to use in your sketch.
Then click on Sketch > Include Library.
#ARDUINO LCD LIBRARY LICENSE ZIP FILE#
Navigate to zip file you downloaded and open it.
Then in your Arduino IDE, click on the menu item Sketch > Include Library > Add.
This will download the library files to your computer.
At the Github repository for the Arduino version of I2cCharDisplay library click on “Download ZIP” button above the list of files (you may need to be signed in to Github to see this button).
The following is one of the easiest methods. For more hardware information see the following links.Īrduino provides several methods for installing libraries. Some character displays have I☬ built in, or a backpack board can be mounted on the back of the display board. This makes it easy to connect many devices (sensors, displays, motors, etc.) to a microcontroller. The I☬ communication standard only uses 2 pins on the microcontroller to communicate with many I☬ devices.
your OLED display module has the commonly used US2066 controller chip (which has I☬ built in).
your LCD character display has the commonly used HD44780 controller chip and has a I☬ PCA8574 i/o expander chip on a backpack board (which gives the display I☬ capability).
16×2, 20×2, 20×4, etc.) and are available in a variety of colors. LCD and OLED character displays come in a variety of sizes (e.g.

The I2cCharDisplay library works with Arduino, Particle (Photon, Electron, and Core) and Raspberry Pi boards and it provides many functions to communicate with OLED and LCD character display modules that use the I☬ communication protocol.
