The Neopixel display has wonkyness that I can't blame entirely on RF reflections. I discovered Paul's non-blocking library which would go a long way to fixing some problems. I tried running some of Paul's examples. They were doing something but not what they were supposed to do. I also saw his warning about using 5 V signals to drive the array. I have been using the Adafruit library and did see some problems due to driving with 3.3 V. Fortunately I have some spare LM339 comparitor sections running at 5 V that should work. I also saw a non-blocking WS2812 library for RGB+W LEDs and relized my problem with Paul's example. The good new is the RGB only rings are cheaper! Paul is brilliant!
