CircuitPython 3.0.1 breaks built in NeoPixel on Feather M4 Express #1140
Description
After upgrading to CP 3.0.1, built in NeoPixel does't work anymore. It doesn't indicate the CP state with green/white and driving it with code has no effect.
Code below works in 3.0.0, doesn't work in 3.0.1
import time
import board
import neopixel
led = neopixel.NeoPixel(board.NEOPIXEL, 1)
led.brightness = 0.3
while True:
led[0] = (255, 0, 0)
time.sleep(0.5)
led[0] = (0, 255, 0)
time.sleep(0.5)
led[0] = (0, 0, 255)
time.sleep(0.5)
