DMX to LED Shield (DEV-15110) project guidance

Any suggestions for libraries/sketches to get started with a MQTT->DMX bridge? More specifically, I want to pass through DMX data from the existing master DMX mixer to the slave lights and inject commands from the DMX shield via MQTT.

After looking at the examples, I have a DMX->MQTT bridge working where it just reports the DMX channel data. A couple questions:

  1. Channel 1 on my DMX master/mixer shows as channel 2 from the SparkFunDMX library and the rest of the channels are offset accordingly.

  2. Is there a way to detect whether there is any actual incoming/new DMX data? I can unplug the DMX input but the library keeps reporting the last known data.
