neopixel_write – Low-level neopixel implementation
The neopixel_write module contains a helper method to write out bytes in
the 800khz neopixel protocol.
For example, to turn off a single neopixel (like the status pixel on Express boards.)
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)
Note
This module is typically not used by user level code.
For more information on actually using NeoPixels, refer to the CircuitPython Essentials Learn guide
For a much more thorough guide about using NeoPixels, refer to the Adafruit NeoPixel Überguide.
Available on these boards
- neopixel_write.neopixel_write(digitalinout: digitalio.DigitalInOut, buf: circuitpython_typing.ReadableBuffer) None
Write buf out on the given DigitalInOut.
- Parameters:
digitalinout (DigitalInOut) – the DigitalInOut to output with
buf (ReadableBuffer) – The bytes to clock out. No assumption is made about color order
