【Micropython 8266】AP模式下通过HTTP网页获取GPIO引脚状态
- ✨本案例基于
Thonny平台开发。✨
-📌通过 访问页面获取ESP8266引脚状态信息
- 🌿横向排版显示
⛳连接和访问
- 📍程序运行后，通过电脑或手机连接micropython设备的WiFi。
- 📌Shell调试窗口将打印被连接上的设备IP地址.
📝示例代码
from machine import Pin
import network
# 设置要读取的GPIO引脚，并设置为输入模式
pins = [Pin(i, Pin.IN) for i in (0, 2, 4, 5, 12, 13, 14, 15)]
# 访问端返回的信息
