Regarding Teensy 3.6 and FASTled (and pulling out hair!) … I’m trying to write my own lightsaber code and have the audio working off the built in sdcard very well using mixers etc, and now want to move on to using the WS2812 LED strings, but if I’m correct there isn’t any official support for the 3.6 in FASTled yet? However, I have read that someone had this working by using a different branch? I’ve tried everything I can find but cannot get the sketch to compile as it’s giving “Invalid pin specified” errors. Are there any magicians among you that have got this to work or can point me in the right direction please? I’m still somewhat newbie at this so may be missing something very obvious.
