PIO-driven 8-way concurrent NeoPixel driver for RP2040

Dependencies

This driver depends on:

• Adafruit CircuitPython <https://github.com/adafruit/circuitpython>_
• pioasm <https://github.com/adafruit/Adafruit_CircuitPython_pioasm>_

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle <https://circuitpython.org/libraries>_ or individual libraries can be installed using circup <https://github.com/adafruit/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:

.. code-block:: shell

pip3 install circup

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

.. code-block:: shell

circup install neopxl8

Or the following command to update an existing version:

.. code-block:: shell

circup update

Usage Example

See the Examples page <examples.html>_ 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:

.. code-block:: python

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(
    first_led_pin,
    num_pixels,
    num_strands=num_strands,
)

pixels.fill(0x01_00_00)

while True:
    time.sleep(1)
