驱动led

led闪烁

from machine import Pin
import time
​
led = Pin('LED',Pin.OUT)
​
while True:
    led.toggle()
    time.sleep(0.5)

 

 

驱动OLED

使用ssd1306库

from machine import Pin, I2C
i2c1 = I2C(1,sda=Pin(6), scl=Pin(7))
​
from ssd1306 import SSD1306_I2C
oled = SSD1306_I2C(128, 64, i2c1)
​
import time
​
oled.fill(1)
oled.show()
time.sleep(1.0)
​
oled.fill(0)
oled.show()
time.sleep(1.0)
​
​
oled.text('Hello', 0, 0)
oled.text('World', 0, 10)
oled.show()

 

驱动蜂鸣器

使用gpio16引脚

from machine import Pin, PWM
import utime
​
pwm0 = PWM(Pin(16))      # create PWM object from a pin
pwm0.freq()             # get current frequency
pwm0.freq(1000)         # set frequency
pwm0.duty_u16()         # get current duty cycle, range 0-65535
pwm0.duty_u16(1000)      # set duty cycle, range 0-65535
​
utime.sleep(1.0)
pwm0.deinit()           # turn off PWM on the pin

这用Python写代码真是简单呀。
