NeoPixel Test Not Working
I can't get the NeoPixel to work.
I am using the standard builtin Neopixel library: https://docs.micropython.org/en/latest/library/neopixel.html
from machine import Pin
from neopixel import NeoPixel
from utime import sleep
NEOPIXEL_PIN = 23
NUMBER_PIXELS = 1
# initialize objects
led = Pin(NEOPIXEL_PIN, Pin.OUT)
strip = NeoPixel(led, NUMBER_PIXELS)
counter = 0
while True:
print('c:', counter)
strip[0] = (255,255,255)
strip.write()
sleep(.5)
strip[0] = (0,0,0)
strip.write()
sleep(.5)
counter += 1I am running the latest version of the runtime:
