9/26/2023 0 Comments Arduino software wire libraryIf you want to use more than one display, they need to have different addresses (more on this in the video) and this library can either autodetect them or you can specify the addresses (detail on this is in the gitHub documentation and in the example sketches. The ESP32 has a Wire library that is compatible with the Arduino Wire. When using the ESP32 with the Arduino IDE, use the Wire.h library to communicate with devices using I2C. This library will autodetect your I2C displays and you do not need to specify the address of the device. I have used, in the Arduino IDE, both the I2C and SPI API in the Arduino IDE.The example sketches will then also be available in the Open file dialogue. In the library manager, search for hd44780 and then download it - it will soon be ready to use and will appear in your libraries menu. The best way to get the library is to open your Arduino software and go to the menu:.They span from a Sketch Bare Minimum to Digital and Analog IO, to the use of Sensors and Displays. These simple programs demonstrate all basic Arduino commands. Since that video was made, we have switched to using the hd44780 Library:Ĭreated by Bill Perry example code is unlicensed and is released into the public domain Built-in Examples are sketches included in the Arduino Software (IDE), to open them click on the toolbar menu: File > Examples. Wire is already included in the Arduino IDE but you will need to download NewLiquidCrystal - click here to download: In our video, we used the NewLiquidCrystal Library. T o use an I2C ready LCD Display or I2C Backpack Adaptor Module with Arduino you will need the Wire Library and a Library for I2C LCD. I2C Arduino Code for LCD Displays & Adaptor ModulesĬlick Here to watch our YouTube Video for a full description
