MicroPython简介

– 动态开发

– OTA开发

– 更便捷的文件管理

– 丰富的开源库让开发更加便捷

– Python语言学习

1.esp8266 使用MicroPython(esp01s成功)

1.1 安装驱动

如果您还没有安装好NodeMCU驱动,需要安装,我已经安装过了

下载驱动程序
 

准备工作
1.2下载安装软件
下载安装Python到电脑
下载安装Putty
1.3为NodeMCU刷入MicroPython固件
MicroPython固件下载

点击

download→esp8266 nodemcu→Stable firmware, 2M or more of flash→last(最新的)


1.4 下载安装pytools

进入python的Scripts文件夹下

cd C:\Users\yys53\OneDrive\python\install\Scripts
pip.exe install esptool

然后再当前文件夹运行,下面命令,清除esp8255,记住端口号

esptool.py.exe --port COM3 erase_flash

esptool.py v3.0

最后输入micropython


1.5 为NodeMCU开发板刷MicroPython固件

esptool.py.exe --port COM3 --baud 115200 write_flash --flash_size=detect 0 F:\F盘\软件\micropython\esp8266nodemcu\esp8266-20210203-unstable-v1.14.bin

1.6 用putty输入最简单Micropython语句测试安装成功

打开putty

session→connect type→serial→

session→Serial line →COM3→speed→115200

connection→SSH→Serial Flow control→None

2.linux输入 esp8266

  • Python3 + pip3 ($ sudo apt install python3-pip)；
  • esptool ($ pip3 install --user esptool)；
pip3 install --user esptoo
  • MicroPython for ESP8266 固件 ? 点我下载；
  • WebREPL 工具 -- 最大用途莫过于用来上传下载 micropython 程序文件；
    • ? 点我下载。
    • 也可以使用官方在线版本直接运行（只是为浏览器加载了 html/js/css 等文件而已，运行时仍然是本地的）。
  • minicom -- LINUX 上的串口终端。
sudo apt install minicom

3.MicroPython WebREPL 命令行交互环境设置

3.1 连接wifi

import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('yang1234', 'y123456789')

看ip地址

wlan.ifconfig()
import webrepl

如果第一次import webrepl 会选择E,然后设置密码,记住密码123456
 

webrepl.start()


WebREPL daemon started on ws://192.168.4.1:8266
WebREPL daemon started on ws://192.168.31.140:8266
 

 

接下来请打开WebREPL文件包中的webrepl.html文件，输入ip 192.168.31.140:8266就可以
