DEPRECATED - This library has been copied and renamed¶
The new version of this library is https://github.com/adafruit/Adafruit_CircuitPython_Pixelbuf.
This old version has been archived and will not be maintained. The import name was
adafruit_pypixelbuf, and is now:
On many boards, there is a native implementation of
adafruit_pixelbuf, and this Python version is not needed.
Pure python implementation of _pixelbuf for smaller boards.
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-pypixelbuf
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-pypixelbuf
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-pypixelbuf
This example tests that pypixelbuf works.
class TestBuf(adafruit_pypixelbuf.PixelBuf): called = False def show(self): self.called = True buffer = TestBuf(20, bytearray(20 * 3), "RGB", 1.0, auto_write=True) buffer = (1, 2, 3)
