If your default Python is version 3 you may need to run 'pip' instead. Just make sure you aren't trying to use

CircuitPython on Python 2.x, it isn't supported!

CircuitPython & Python Usage

To demonstrate the usage of the this library with DotStar LEDs, we'll use the board's Python REPL.

If you're using a SPI connection run the following code to import the necessary modules and initialize SPI with a strip of

30 DotStars:

Or if you're using bit banged pins, run the following code:

Now you're ready to light up your DotStar LEDs using the following properties:

brightness - The overall brightness of the LED

fill - Color all pixels a given color.

show - Update the LED colors if auto_write is set to False .

For example, to light up the first DotStar red:

To light up all the DotStars green:

import board

import adafruit_dotstar as dotstar

dots = dotstar.DotStar(board.SCK, board.MOSI, 30, brightness=0.2)

import board

import adafruit_dotstar as dotstar

dots = dotstar.DotStar(board.D6, board.D5, 30, brightness=0.2)

dots[0] = (255, 0, 0)

dots.fill((0, 255, 0))
