[Python知识库]ESP8266 MicroPython初尝试

一、下载MicroPython

????????到MicroPython的官网下载基于ESP8266的MicroPython固件，目前最新稳定版本为esp8266-20210618-v1.16.bin

二、烧写MicroPython固件

? ? ? ? 烧写工具下载：flash_download_tool_3.8.8

? ? ? ? 烧写之前最好先擦除一下FLASH

????????

三、打开串口终端，波特率为115200，重启输出以下信息说明烧写成功

MicroPython v1.16 on 2021-06-18; ESP module with ESP8266
Type "help()" for more information.
>>> 

四、连接网络

import network
wlan = network.WLAN(network.STA_IF)
wlan.active(True)
wlan.connect('SSID', 'PASSWORD')
wlan.ifconfig()

?

五、使用webrepl上传文件

输入import webrepl_setup进行使能并设置密码

>>> import webrepl_setup
WebREPL daemon auto-start status: enabled

Would you like to (E)nable or (D)isable it running on boot?
(Empty line to quit)
> E
Would you like to change WebREPL password? (y/n) y
New password (4-9 chars): 12345678
Confirm password: 12345678
No further action required
>>> 

打开webrepl客户端工具，上传main.py

WebREPL在线版http://micropython.org/webrepl/

# main.py
import network
import webrepl
import utime
from machine import Pin

SSID = "xxxx"
PASSWORD = "xxxx"

def do_connect():
    import network  
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print('connecting to network')
        wlan.connect(SSID,PASSWORD)
    
    start = utime.time()
    while not wlan.isconnected():
        utime.sleep(1)
        if utime.time()-start > 5:
            print("connect timeout")
            break;
    if wlan.isconnected():
        print('network config', wlan.ifconfig())

def led_test():
    p2 = Pin(2, Pin.OUT)
    for i in range(10):
        p2.value(1)
        utime.sleep(1)
        p2.value(0)
        utime.sleep(1)
        
do_connect()
led_test()
