Introduction

Neopixel and Dotstar Framebuffer Helper

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Adafruit LED Animation
• Adafruit framebuf

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-pixel-framebuf

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-pixel-framebuf

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-pixel-framebuf

Usage Example

"""
This example runs on an Adafruit NeoPixel Feather
"""
import board
import neopixel
from adafruit_pixel_framebuf import PixelFramebuffer

pixel_pin = board.D6
pixel_width = 8
pixel_height = 4

pixels = neopixel.NeoPixel(
    pixel_pin,
    pixel_width * pixel_height,
    brightness=0.1,
    auto_write=False,
)

pixel_framebuf = PixelFramebuffer(
    pixels,
    pixel_width,
    pixel_height,
    alternating=False,
)

pixel_framebuf.fill(0x000088)
pixel_framebuf.pixel(5, 1, 0xFFFF00)
pixel_framebuf.line(0, 0, pixel_width - 1, pixel_height - 1, 0x00FF00)
pixel_framebuf.display()
