CircuitPython library for DotStar LEDs.
Project description
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.
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-dotstarTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-dotstarTo 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-dotstarUsage Example
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[0] = (10, 0, 0)Documentation
API documentation for this library can be found on Read the Docs.
