Is it at the moment possible to run a teensy 3.1 with FastLED or am I doing a fault? Everytime I’m getting faults…
Not yet. There’s some work that needs to be done to support the teensy 3.1 - there will be an announcement here and on the site when it is ready.
thanks Daniel 
Can’t wait! Project is on hold. 
Cool, can’t wait to get Glediator running with Teensy3.1
