public class SSD1331
extends ColourSsdOled

Encapsulates the serial interface to the 16-bit colour (5-6-5 RGB) SSD1331 96x64 OLED display hardware. On creation, an initialisation sequence is pumped to the display to properly configure it. Further control commands can then be called to affect the brightness and other settings.

Method Details

init

protected void init()

Specified by:

init in class SsdOled

goTo

protected void goTo(int x,
int y)

Specified by:

goTo in class SsdOled

invertDisplay

public void invertDisplay(boolean invert)

Sets if the display should be inverted

Specified by:

invertDisplay in class SsdOled

Parameters:

invert - Invert state

setContrast

public void setContrast(byte level)

Switches the display contrast to the desired level, in the range 0-255. Note that setting the level to a low (or zero) value will not necessarily dim the display to nearly off. In other words, this method is **NOT** suitable for fade-in/out animation.

Specified by:

setContrast in class ColourSsdOled

Parameters:

level - Desired contrast level in the range 0..255

setContrast

public void setContrast(byte red,
byte green,
byte blue)

Specified by:

setContrast in class ColourSsdOled
