关于#python#的问题：但是自己在学习的时候发现下面的代码亮不了

Question

用树莓派4b，写的接线没问题，网上的代码，但是自己在学习的时候发现下面的代码亮不了，help！

```python
import time
from rpi_ws281x import PixelStrip, Color

LED_COUNT = 30      # LED灯的个数
LED_PIN = 18          # DI端接GPIO18
 
# 以下可以不用改
LED_FREQ_HZ = 800000  # LED signal frequency in hertz (usually 800khz)
LED_DMA = 10          # DMA channel to use for generating signal (try 10)
LED_BRIGHTNESS = 255  # Set to 0 for darkest and 255 for brightest
LED_INVERT = False    # True to invert the signal (when using NPN transistor level shift)
LED_CHANNEL = 0       # set to '1' for GPIOs 13, 19, 41, 45 or 53
strip = PixelStrip(LED_COUNT, LED_PIN, LED_FREQ_HZ, LED_DMA, LED_INVERT, LED_CHANNEL)

strip.begin()

strip.setPixelColor(1, Color(255, 255, 0))

strip.show()

Answer 1

接线接对了吗，如果没问题那就是没输出，要么是驱动问题，要么就是代码问题
