|
|
// A quick demo of how to use my OLED_I2C library.
|
|
//
|
|
// To use the hardware I2C (TWI) interface of the Arduino you must connect
|
|
// the pins as follows:
|
|
//
|
|
// Arduino Uno/2009:
|
|
// ----------------------
|
|
// Display: SDA pin -> Arduino Analog 4 or the dedicated SDA pin
|
|
// SCL pin -> Arduino Analog 5 or the dedicated SCL pin
|
|
//
|
|
// Arduino Leonardo:
|
|
// ----------------------
|
|
// Display: SDA pin -> Arduino Digital 2 or the dedicated SDA pin
|
|
// SCL pin -> Arduino Digital 3 or the dedicated SCL pin
|
|
//
|
|
// Arduino Mega:
|
|
// ----------------------
|
|
// Display: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA pin
|
|
// SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL pin
|
|
//
|
|
// Arduino Due:
|
|
// ----------------------
|
|
// Display: SDA pin -> Arduino Digital 20 (SDA) or the dedicated SDA1 (Digital 70) pin
|
|
// SCL pin -> Arduino Digital 21 (SCL) or the dedicated SCL1 (Digital 71) pin
|
|
//
|
|
// The internal pull-up resistors will be activated when using the
|
|
// hardware I2C interfaces.
|
|
//
|
|
// You can connect the OLED display to any available pin but if you use
|
|
// any other than what is described above the library will fall back to
|
|
// a software-based, TWI-like protocol which will require exclusive access
|
|
// to the pins used, and you will also have to use appropriate, external
|
|
// pull-up resistors on the data and clock signals.
|
|
