【RPi PICO】呼吸灯

[shaoziyang]

RPi PICO大部分引脚都支持PWM，所以可以很方便的实现呼吸灯效果。

Code: Select all

from machine import Pin, Timer, PWM

LED = PWM(Pin(25))

n = 0

def breathing(t):
global n
LED.duty_u16(abs(32000- n*1000))
n = (n + 1) % 64

T0 = Timer(-1)
T0.init(period=20, mode=Timer.PERIODIC, callback=breathing)
