"""
|
|
This example shows usage of the PixelMap helper to easily treat a single strip as a horizontal or
|
|
vertical grid for animation purposes.
|
|
|
|
For NeoPixel FeatherWing. Update pixel_pin and pixel_num to match your wiring if using
|
|
a different form of NeoPixels. Note that if you are using a number of pixels other than 32, you
|
|
will need to alter the PixelMap values as well for this example to work.
|
|
|
|
This example does not work on SAMD21 (M0) boards.
