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. Github repository for the Raspberry Pi software library.Github repository for the Particle software library.Github repository for the Arduino software library.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.
