15. LED例程讲解

1. 概述

K230开发板板载1颗LED灯，可通过machine.LED来控制灯珠

2. 示例

from machine import LED
import time

red_led = LED("LED_RED")          #或者red_led = LED(1)
green_led = LED("LED_GREEN")      #或者green_led = LED(2)
blue_led = LED("LED_BLUE")        ##或者blue_led = LED(3)
blue_led.off()
green_led.off()
red_led.off()

while(1):
    green_led.value(50)    #取值0-255
    red_led.on()
    time.sleep_ms(250)
    green_led.value(200)
    red_led.off()
    time.sleep_ms(250)

提示

LED模块具体接口请参考API文档
