CircuitPython library for mapping multiple neopixels to behave as one for the purposes of setting colors or showing animations.
This driver depends on:
Adafruit CircuitPython <https://github.com/adafruit/circuitpython>
_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>
_.
NeoPixel Products <https://www.adafruit.com/category/168>
_On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI <https://pypi.org/project/adafruit-circuitpython-pixelmap/>
_.
To install for current user:
.. code-block:: shell
pip3 install adafruit-circuitpython-pixelmap
To install system-wide (this may be required in some cases):
.. code-block:: shell
sudo pip3 install adafruit-circuitpython-pixelmap
To install in a virtual environment in your current project:
.. code-block:: shell
mkdir project-name && cd project-name
python3 -m venv .venv
source .env/bin/activate
pip3 install adafruit-circuitpython-pixelmap
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 adafruit_pixelmap
Or the following command to update an existing version:
.. code-block:: shell
circup update
.. code-block:: python
import board
import neopixel
import time
from adafruit_pixelmap import PixelMap, horizontal_strip_gridmap, vertical_strip_gridmap
# Update to match the pin connected to your NeoPixels
pixel_pin = board.NEOPIXEL
# Update to match the number of NeoPixels you have connected
pixel_num = 32
pixels = neopixel.NeoPixel(pixel_pin, pixel_num, brightness=0.1, auto_write=True)
pixel_wing_vertical = PixelMap.vertical_lines(
pixels, 8, 4, horizontal_strip_gridmap(8, alternating=False)
)
pixel_wing_horizontal = PixelMap.horizontal_lines(
pixels, 8, 4, horizontal_strip_gridmap(8, alternating=False)
)
for row in range(len(pixel_wing_horizontal)):
pixels.fill(0x00000)
pixel_wing_horizontal[row] = 0x00ff00
time.sleep(0.3)
for row in range(len(pixel_wing_vertical)):
pixels.fill(0x00000)
pixel_wing_vertical[row] = 0xff00ff
time.sleep(0.3)
