Neopixel not working on YD-RP2040 #167

Description

@aguaviva

I tried the following samples:

1- native sample

import board
import neopixel_write
import digitalio

pin = digitalio.DigitalInOut(board.NEOPIXEL)
pin.direction = digitalio.Direction.OUTPUT
pixel_off = bytearray([128, 0, 0])
neopixel_write.neopixel_write(pin, pixel_off)

2- installing neopixel using:

$ circup --path /media/raul/CIRCUITPY/ install neopixel

and running

import time
import board
import neopixel

pixel = neopixel.NeoPixel(board.NEOPIXEL, 1)

pixel.brightness = 0.3

while True:
    pixel.fill((255, 0, 0))
    time.sleep(0.5)
    pixel.fill((0, 255, 0))
    time.sleep(0.5)
    pixel.fill((0, 0, 255))
    time.sleep(0.5)
