|
|
// A quick demo of how to use my OLED_I2C library.
|
|
//
|
|
// To use the hardware I2C (TWI) interface of the chipKit you must connect
|
|
// the pins as follows:
|
|
//
|
|
// chipKit Uno32/uC32:
|
|
// ----------------------
|
|
// Display: SDA pin -> Analog 4
|
|
// SCL pin -> Analog 5
|
|
// *** Please note that JP6 and JP8 must be in the I2C position (closest to the analog pins)
|
|
//
|
|
// chipKit Max32:
|
|
// ----------------------
|
|
// Display: SDA pin -> Digital 20 (the pin labeled SDA)
|
|
// SCL pin -> Digital 21 (the pin labeled SCL)
|
|
//
|
|
// The chipKit boards does not have pull-up resistors on the hardware I2C interface
|
|
// so external pull-up resistors on the data and clock signals are required.
|
|
//
|
|
// 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.
|
|
