A full Arduino class library of SSD1306_OLED_HW_I2C. The original SSD1306_OLED_HW_I2C was not a class, but rather a collection of routines. An enhanced base class can be found here, ...

This code enables OLED display initialization, text printing and screen update. If your OLED display's I2C address is not 0x3C, you may need to edit the display.begin (SSD1306_SWITCHCAPVCC, 0x3C) line ...

To get it running with Arduino, a couple of libraries need to be included. The “Wire” library for I 2 C communication is already available in the Arduino IDE.
