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)
|
|
|
|
|
|
