There are two parts here:
1. The general pattern trigger (which is not yet upstream),
2. A way to supply a string, convert it into morse code, and feed it to
the LED subsystem.
Given 1 is not yet upstream, I think Andreas solution is fine.
Once 1 is upstream, 2 can be modified to feed into 1, if available.
Do you agree?
Thanks!
