```
public abstract class HT16K33
 implements DeviceInterface
                    
```
I2C-based LED matrix driver. Inspired by Adafruit's HT16K33 library
NOTE According to some implementations of this chip, it can be inconsistent, so there is a very small number of retries that are attempted on all writes to each device in the chain.
