It will save at least 4 digital / analog pins on Arduino. I got this LCD display that comes with a nice I2C backpack and is Arduino (and hence I guess ATmega) compatible. There are many of them out there, and you can usually tell them by the 16-pin interface. With I2C module you will be able to connect the LCD with Arduino board with only two cables! The i2c module has a built in potentiometer for contrast adjustment. Free AutoCAD Tutorial Courses; About Us. Download the library, a zip file (you can download it from here ) and extract the contents in the libraries folder of the Arduino IDE. Add to Cart. Also,in Arduino,libraries for LCD and I2C(Wire. 2017 (commit e3701fb). Tutorial: Arduino and the I2C bus - Part One In this first of several tutorials we are going to investigate the I2C data bus, and how we can control devices using it with our Arduino systems. The I2C bus can be a complex interface to master, so we will do my best to simplify it for you. Arduino I2C Interface. Marlin/Sd2Card. print(data). This would be a big addition to the LCD use. * After creating an instance of this class, first call begin() before anything else. I used Fluerry's LCD library and also arduino in order to check that my LCD hardware is working. In the case you use the I2C communication between LCD and microcontroller, you need to know the I2C HEX address of the LCD. Data is transmitted using only 2 wire over i2c with the PCF8574.
