教材：Getting started with Raspberry Pi Pico

MicroPython for Pico：Quick reference for the RP2

範例一：LED閃爍控制

1 2 3 4 5 6 7

from machine import Pin import time led = Pin(26, Pin.OUT) while True: led.toggle() time.sleep(1)

範例二：採用硬體計時器

1 2 3 4 5 6 7 8

from machine import Pin, Timer led = Pin(26, Pin.OUT) timer = Timer() def blink(timer): led.toggle() timer.init(freq=1, mode=Timer.PERIODIC, callback=blink)

範例三、輸入輸出

1 2 3 4 5 6 7 8 9 10

from machine import Pin import time led = Pin(26, Pin.OUT) button = Pin(27, Pin.IN, Pin.PULL_DOWN) while True: if button.value(): led.toggle() time.sleep(0.5)
