CircuitPython library for DotStar LEDs.
Adafruit CircuitPython DotStar
Higher level DotStar driver that presents the strip as a sequence. It is the same api as the NeoPixel library.
Colors are stored as tuples by default. However, you can also use int hex syntax to set values similar to colors on the web. For example, 0x100000 (#100000 on the web) is equivalent to (0x10, 0, 0).
If you send a tuple with 4 values, you can control the brightness value, which appears in DotStar but not NeoPixels. It should be a float. For example, (0xFF,0,0, 1.0) is the brightest red possible, (1,0,0,0.01) is the dimmest red possible.
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-dotstar
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-dotstar
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-dotstar
This example demonstrates the library with the single built-in DotStar on the Trinket M0 and Gemma M0.
import board import adafruit_dotstar pixels = adafruit_dotstar.DotStar(board.APA102_SCK, board.APA102_MOSI, 1) pixels = (10, 0, 0)
API documentation for this library can be found on Read the Docs.
