The library assumes you are using the only pins with hardware support for i2c on the Nano, so you don't have to specify pin numbers. by Floris Wouterlood – the Netherlands – July 4, 2017. You will become an expert and be able to make your own libraries with this video. There’s also a tutorial on writing your own libraries; and further, you may refer to Arduino’s API Style Guide for some guidelines on making a good Arduino-style API for your library. The library and files all contain the word "wire" because Atmel (the chip at the heart of the Arduino) devised a system called "Two Wire Interface" or "TWI" which is their flavor of I2C. In this article I will show you how to make a circuit that measures. LiquidCrystal library with object support to allow for multiple kinds of connections (3 wires through shift registers, or even a 2 wire SR hack) I2C support is unmaintained and probably broken - marcmerlin/NewLiquidCrystal. rename the folder as exactly LiquidCrystal_I2C. Therefore, any project that you have developed is fully compatible with this library by just changing two lines of code (an include and the object creation - variable creation). This makes controlling the code version easily and any changes does not need to re-flash all the 8 I2C slaves.
