neopixel_write –低级新像素实现

neopixel_write 模块包含一个辅助方法,用于在 800khz neopixel 协议中写出字节。

例如,关闭单个新像素(如 Express 板上的状态像素。)

import board
import neopixel_write
import digitalio

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