PIO-driven 8-way concurrent NeoPixel driver for RP2040


This driver depends on:

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install neopxl8

Or the following command to update an existing version:

circup update

Usage Example

See the Examples page for a full example. This example shows how to set up 8 30-pixel LED strands on an Adafruit Feather Scorpio RP2040 and set them all to dim red:

import time
import board
from adafruit_neopxl8 import NeoPxl8

# Customize for your strands here
num_strands = 8
strand_length = 30
first_led_pin = board.NEOPIXEL0

num_pixels = num_strands * strand_length

# Make the object to control the pixels
pixels = NeoPxl8(
