Library: OLED_I2C

This library has been made to make it easy to use 128x32 and 128x64 pixel OLED displays based on the SSD1306 controller chip with an Arduino, chipKit, ESP8266 or ESP32.

This library will default to I²C Fast Mode (400 KHz) when using the hardware I²C interface.

IMPORTANT:

There are some important changes from v1.xx. If you are upgrading from an older version of the library you should read about the changes in the manual.

The library has not been tested in combination with the Wire library and I have no idea if they can share pins. Do not send me any questions about this. If you experience problems with pin-sharing you can move the displays SDA and SCL pins to any available pins on your development board. This library will in this case fall back to a software-based, TWI-/I²C-like protocol which will require exclusive access to the pins used.

Some demos showcasing most of the functions are included in the download.
This is a multi-platform library that will work with several different development board types.
