# APA102 driver
# Use the apa102 module:

from machine import Pin
from apa102 import APA102

clock = Pin(14, Pin.OUT)     # set GPIO14 to output to drive the clock
data = Pin(13, Pin.OUT)      # set GPIO13 to output to drive the data
apa = APA102(clock, data, 8) # create APA102 driver on the clock and the data pin for 8 pixels
apa[0] = (255, 255, 255, 31) # set the first pixel to white with a maximum brightness of 31
apa.write()                  # write data to all pixels
r, g, b, brightness = apa[0] # get first pixel colour
For low-level driving of an APA102:

import esp
esp.apa102_write(clock_pin, data_pin, rgbi_buf)
