The NeoPixel example from the MicroPython rp2 docs is as follows:
from machine import Pin
from neopixel import NeoPixel
pin = Pin(0, Pin.OUT) # set GPIO0 to output to drive NeoPixels
np = NeoPixel(pin, 8) # create NeoPixel driver on GPIO0 for 8 pixels
np[0] = (255, 255, 255) # set the first pixel to white
np.write() # write data to all pixels
r, g, b = np[0] # get first pixel colour
The example gives a warning on the np[0] = (255, ...) line, because it can't find the __setitem__ method of the NeoPixel class.
