NeoPixel驱动程序
使用neopixel模块:
from machine import Pin from neopixel import NeoPixel pin = Pin(0, Pin.OUT) # set GPIO0 to output to drive NeoPixels np = NeoPixel(pin, 8) # create NeoPixel driver on GPIO0 for 8 pixels np[0] = (255, 255, 255) # set the first pixel to white np.write() # write data to all pixels r, g, b = np[0] # get first pixel colour
对于NeoPixel的低级驱动:
import esp esp.neopixel_write(pin, grb_buf, is800khz)
