 24  PIO-driven 8-way concurrent NeoPixel driver for RP2040
 25  
 26  
 27  Dependencies
 28  =============
 29  This driver depends on:
 30  
 31  * `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_
 32  * `pioasm <https://github.com/adafruit/Adafruit_CircuitPython_pioasm>`_
 33  
 34  Please ensure all dependencies are available on the CircuitPython filesystem.
 35  This is easily achieved by downloading
 36  `the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
 37  or individual libraries can be installed using
 38  `circup <https://github.com/adafruit/circup>`_.
 39  
 40  Installing to a Connected CircuitPython Device with Circup
 41  ==========================================================
 42  
 43  Make sure that you have ``circup`` installed in your Python environment.
 44  Install it with the following command if necessary:
 45  
 46  .. code-block:: shell
 47  
 48      pip3 install circup
 49  
 50  With ``circup`` installed and your CircuitPython device connected use the
 51  following command to install:
 52  
 53  .. code-block:: shell
 54  
 55      circup install neopxl8
 56  
 57  Or the following command to update an existing version:
 58  
 59  .. code-block:: shell
 60  
 61      circup update
 62  
 63  Usage Example
 64  =============
 65  
 66  See the `Examples page <examples.html>`_ for a full example.  This example shows how to set up 8 30-pixel LED strands on an Adafruit Feather Scorpio RP2040 and set them all to dim red:
 67  
 68  .. code-block:: python
 69  
 70      import time
 71      import board
 72      from adafruit_neopxl8 import NeoPxl8
 73  
 74      # Customize for your strands here
 75      num_strands = 8
 76      strand_length = 30
 77      first_led_pin = board.NEOPIXEL0
 78  
 79      num_pixels = num_strands * strand_length
 80  
 81      # Make the object to control the pixels
 82      pixels = NeoPxl8(
 83          first_led_pin,
 84          num_pixels,
 85          num_strands=num_strands,
 86      )
 87  
 88      pixels.fill(0x01_00_00)
 89  
 90      while True:
 91          time.sleep(1)
 92  
 93
