Hello, I am starting with my second Teensy for an LED project. I have one working right now using a Teensy 3.2 and 5v LEDs. I am about to start wiring up my 12v LED setup. I will be powering the LEDs (WS2811) externally with a 12v power supply. The Teensy will be powered over USB from the computer driving the display. My question is with the grounds. So I need to use the LED strip ground pin for the LED 12v power. I also would need to wire the teensy signal ground to that as well. I am pretty sure that would be okay but I wanted to double check on this before finishing my plans for this project.
Thanks!
Thanks!
