I am using a Teensy 3.2 and FastLED to control a strip of 840 12 Volt WS2812 LED's.
I'll be powering the Teensy from the 12 volts powering the LED's through a Buck Converter that has the output voltage dialed down to 5.0 volts.
Here is my problem; when I have the Teensy on the workbench powered through a USB cable connected to my PC; everything runs perfect. When I remove the USB and try to power the Teensy from the Buck Converter, the Teensy does not work. I've tested the Pins on the Teensy and I'm getting 5.0 volts to the GND and Vin pins and the voltage is the correct polarity.
I am stumped.
Any similar experience with this problem out there?
Appreciate the help,
Bob
