"""
Blink example for boards with ONLY a NeoPixel LED (e.g. without a built-in red LED).
Includes QT Py and various Trinkeys.
Requires two libraries from the Adafruit CircuitPython Library Bundle.
Download the bundle from circuitpython.org/libraries and copy the
following files to your CIRCUITPY/lib folder:
* neopixel.mpy
* adafruit_pixelbuf.mpy
Once the libraries are copied, save this file as code.py to your CIRCUITPY
drive to run it.

You may need to press "Stop/Restart" or hard-reset your CircuitPython device and try again.

CircuitPython is throwing this to the console:
Auto-reload is off.
Running in safe mode! Not running saved code.
You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Crash into the HardFault_Handler.
Please file an issue with the contents of your CIRCUITPY drive at
https://github.com/adafruit/circuitpython/issues
Press any key to enter the REPL. Use CTRL-D to reload.
After this, the CircuitPython just does 3 yellow flashes over and over until reset.
