    without seeing code its hard to see what your doing to detect sync on the slave. In my mind the slave needs to be sure to detect a sync from the master and it uses this detection to fire off LED...

    I did not see any reference of octows2811 library . If you are using the octows2811 library then there is no need to define pin 14. It’s predefined. Instead you would use pin 2 for the first...

    Yes . Most of these types of leds really work better with a level shifter. This is why Paul has the octows2811 available to show how to effectively drive the ws281x variants.

    Look at serial with glediator or jinx. If your more adventurous look at adding a w5200/w5500 module and using artnet or sACN to communicate your software to the teensy/octo

    Using the octows2811 and or Fastled method will allow very efficient frame rates over the 8 pins. So if you can divide your pixels over those 8 pins you should see smooth results

    This would be an issue. They have to be exact. If not then you will need to run multiple instances of glediator to accommodate the different setups. And run multiple teensy to make it easy
