Dependencies
|
|
=============
|
|
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://github.com/adafruit/Adafruit_CircuitPython_Bundle>`_.
|
|
|
|
|
|
Installing from PyPI
|
|
=====================
|
|
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
|
|
PyPI <https://pypi.org/project/adafruit-circuitpython-led-animation/>`_. To install for current user:
|
|
|
|
.. code-block:: shell
|
|
|
|
pip3 install adafruit-circuitpython-led-animation
|
|
|
|
To install system-wide (this may be required in some cases):
|
|
|
|
.. code-block:: shell
|
|
|
|
sudo pip3 install adafruit-circuitpython-led-animation
|
|
|
|
To install in a virtual environment in your current project:
|
|
|
|
.. code-block:: shell
|
|
|
|
mkdir project-name && cd project-name
|
|
python3 -m venv .venv
|
|
source .venv/bin/activate
|
|
pip3 install adafruit-circuitpython-led-animation
|
|
|
|
Usage Example
|
|
=============
|
|
|
|
.. code-block:: python
|
|
|
|
import board
|
|
import neopixel
|
|
from adafruit_led_animation.animation.blink import Blink
|
|
import adafruit_led_animation.color as color
|
|
|
|
# Works on Circuit Playground Express and Bluefruit.
|
|
# For other boards, change board.NEOPIXEL to match the pin to which the NeoPixels are attached.
|
|
pixel_pin = board.NEOPIXEL
|
|
# Change to match the number of pixels you have attached to your board.
|
|
num_pixels = 10
|
|
|
|
pixels = neopixel.NeoPixel(pixel_pin, num_pixels)
|
|
blink = Blink(pixels, 0.5, color.PURPLE)
|
|
|
|
while True:
|
|
blink.animate()
|
|

Documentation

Building locally
|
|
================
|
|
|
|
Zip release files
|
|
-----------------
|
|
|
|
To build this library locally you'll need to install the
|
|
`circuitpython-build-tools <https://github.com/adafruit/circuitpython-build-tools>`_ package.
|
|
|
|
.. code-block:: shell
|
|
|
|
python3 -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install circuitpython-build-tools
|
|
|
|
Once installed, make sure you are in the virtual environment:
|
|
|
|
.. code-block:: shell
|
|
|
|
source .venv/bin/activate
|
|
|
|
Then run the build:
|
|
|
|
.. code-block:: shell
|
|
|
|
circuitpython-build-bundles --filename_prefix circuitpython-led_animation --library_location .
|
|
|
|
Sphinx documentation
|
|
-----------------------
|
|
|
|
Sphinx is used to build the documentation based on rST files and comments in the code. First,
|
|
install dependencies (feel free to reuse the virtual environment from above):
|
|
|
|
.. code-block:: shell
|
|
|
|
python3 -m venv .venv
|
|
source .venv/bin/activate
|
|
pip install Sphinx sphinx-rtd-theme
|
|
|
|
Now, once you have the virtual environment activated:
|
|
|
|
.. code-block:: shell
|
|
|
|
cd docs
|
|
sphinx-build -E -W -b html . _build/html
|
|
|
|
This will output the documentation to ``docs/_build/html``. Open the index.html in your browser to
|
|
view them. It will also (due to -W) error out on any warning like Travis will. This is a good way to
|
|
locally verify it will pass.
