All Implemented Interfaces:

DeviceInterface, Closeable, AutoCloseable
```
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.

  - 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,
