All About Errors

  Errors can be shown in many ways in this Sketch:

• They can be ignored.  To simply watch all the pretty DCC commands go by, set 'errorDisplayActive' false in the Sketch. This causes the DCC Monitor to behave essentially like a DCC Decoder and do its best to receive and display the commands. In this mode, errors are only indicated by 'handleErrors()' if the Arduino Serial Monitor is attached.

• If 'errorDisplayActive' is true, 'displayErrors()' will show errors in HUMAN real time on the OLED display. Human real time is much slower than the actual commands are arriving...
