Blink 译为“眨眼、闪烁”,下面通过编程使 Pico 开发板上的 LED 灯不断闪烁,模拟“眨眼”的效果。 Pico 上的这颗 LED 连接到 GPIO 引脚之一的 GP25,正因为这个引脚已经用于在板上连接 LED,所以 Pico 边缘引出的 GPIO 引脚上就没有 GP25 了。这个 LED 的工作原理和其它任何 LED 一样: 通电时,它会发光 ...
Pico 上的这颗 LED 连接到 GPIO 引脚之一的 GP25,正因为这个引脚已经用于在板上连接 LED,所以 Pico 边缘引出的 GPIO 引脚上就没有 GP25 了。这个 LED 的工作原理和其它任何 LED 一样: 通电时,它会发光 当它断电时,熄灭。 下面新建一个 MicroPython 项目来控制这颗 LED 的闪烁。首先导入machine包。 import...
led= Pin(25, Pin.OUT) print('led blink.')whileTrue: led.value(1)time.sleep(0.5) led.value(0)time.sleep(0.5) 3. IDE Thonny VS Code PyCharm 我们一般使用Thonny(支持Windows/Linux)进行刷机、调试、下载代码,编写代码可以使用VS Code或者PyCharm. Thonny 官网:https://thonny.org/ Thonny Github:...
我们来看下使用ESP-IDF和MicroPython来分别让LED发光二极管闪烁的代码。 下面是ESP-IDF官方的C语言点灯代码: /* Blink ExampleThis example code is in the Public Domain (or CC0 licensed, at your option.)Unless required by applicable law or agreed to in writing, thissoftware is distributed on an "AS...
#Copy this code below from the blink.py to the new file #hardware platform: FireBeetle-ESP8266 import time from machine import Pin led=Pin(2,Pin.OUT) #create LED object from pin2,Set Pin2 to output while True: led.value(1) #turn off ...
Now, let’s change the output type. Using the following code, you can make the onboard LED blink: Python importtimeimportmachineblueled=machine.Pin(2,machine.Pin.OUT)# Blink 10 timesforiinrange(1,11):blueled.value(0)time.sleep(0.5)blueled.value(1)time.sleep(0.5)print("DONE!") ...
