Hi every one, has any one used two teensy3.1 controllers to run multiple strips along with two octo2811 adaptors, if so how could I do that, especially do I need to have two sets of codes? I like to run 16 lines on WS2811 LEDs, at the moment has stopped at 8 as I can’t find much info about the setup of two teensy controllers with FastLed along with octo2811, in the PJRC page they talk about video sync. So no idea of how to use this with FastLed.
Thanks for any help.

https://github.com/FastLED/FastLED/wiki/Parallel-Output — FastLED has a 16-way output mode that you can run off of a single teensy - and if I get ambitious i’ll probably put in support for HexaWS2811 much like the OctoWS2811 controller.

I have written a sync class that uses 2 pins for syncing Teensy’s and 1 or more pins for board ID. I have tested it running 3 teensy’s together. I run the same software on each board and just offset the matrix using the board ID. Of course I use my cLEDMatrix class which makes it easy to do the offset.
I haven’t pushed the Sync class onto github yet but if you are interested in it, I can.
