@wsanders
i think so, but i have trouble lighting LEDs with m5stick

i've connect to a led band with grove connector(the default GPIO32 for m5stick). i tried following code but nothing happend...

from m5stack import *
import time
from machine import Pin
from neopixel import NeoPixel

lcd.clear(lcd.WHITE)
lcd.text(lcd.CENTER, lcd.CENTER, "I'm Phelix", lcd.BLACK)

pin = Pin(32, Pin.OUT)
np = NeoPixel(pin, 15)
for i in range(15):
np[i] = (255,255,255)
np.write()

can someone please help me?
