Found out about the countdown timers today. I don't remember ever reading about those before. What I remembered was the RTCLOCK and initially based some code on that. Obviously the countdown timers are easier to use and even have a callback when they reach zreo.

Well it is easier, but wish I hadn't wasted time earlier on the RTClock based timers that I did. OK, now I will work on a simple thing - getting the character set into the app.
