Dependencies¶
This driver depends on:
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 .env
source .env/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()
