Hello How do I know which version of DCC++ or DCC++EX am I running on my Arduino (Uno or Mega)? Is there an easy way to find out? Thanks
With DCC++EX, the version is seen in the startup message when using the Arduino serial monitor. It will also be displayed with the <s> status command. https://dcc-ex.com/reference/software/command-reference.html#status JMRI detects the version for backwards compatibility. It can be seen in the JMRI session.log -- example: INFO - Version set to '4.0.1'
