OLED and I2C Words

oled-emit works like the standard word emit. It blocks the calling thread, as long as the character is not written to the OLED display (less than 300 us for a 6x8 character and 400 kHz I2C). Horizontal (x) position is in pixel (0 to 127), vertical position (y) is in lines, a line consists of 8 pixels. 0, 0 is upper left corner. Larger fonts takes more than one line.

To change the display type you have to edit the oled.h

and rebuild the project:

#define OLED_4PIN_128X32	0		// the cheap one with 4 pins, Adafruit Raspberry Pi #3527
#define	OLED_BONNET_128X64	1		// Adafruit Bonnet for Raspberry Pi #3531
#define OLED_FEATHER_128X32	2		// Adafruit FeatherWing #2900
#define OLED_FEATHER_128X64	3		// Adafruit FeatherWing #4650
#define OLED_OCTOPUS_128X64	4		// Octopus PIS-1277

#define OLED_LANDSCAPE		0
#define	OLED_PORTRAIT		1

// configure your OLED type
#define OLED_DISPLAY_TYPE	OLED_OCTOPUS_128X64
#define	OLED_ORIENTATION	OLED_LANDSCAPE

Usage

It is easy to redirect the terminal output to the OLED display, to use the string formatting words.
