汇思锐模块LED亮灭控制的详细介绍-贝壳物联，让你与智能设备沟通更方便的物联网云平台

在贝壳网站上申请了一片汇思锐的8266开发底板

首先下载乐鑫的固件然后按照下图烧写固件

打开汇思锐调试工具，按照上面一步一步设置

点击airkiss 按钮进入airkiss 配网模式。

一：准备工作

环境搭建：

1、PC端软件，需要安装java ESPlorer

2、固件烧录工具：esp8266 flash升级烧写烧录工具v2.1绿色版

3、烧写教程：参考difiot

4、以上所有资料访问百度云盘

基于nodemuc编程API说明中文版本

二、硬件介绍

汇思锐开发板
开发板标识	汇思锐开发板	NODEMCU引脚	LED等亮
LED1	GPIO4	IO2	低有效
LED2	GPIO14	IO5	高有效
LED3	GPIO12	IO6	低有效
LED4	GPIO5	IO1	低有效

三、程序的编写

init.lua 文件

--init.lua
print("set up wifi mode")
wifi.setmode(wifi.STATION)
wifi.sta.config("JSZLZXBGS","jszlzx123")
--here SSID and PassWord should be modified according your wireless router
wifi.sta.connect()
tmr.alarm(1, 1000, 1, function()
   if wifi.sta.getip()== nil then
       print("IP unavaiable, Waiting...")
   else
       tmr.stop(1)
       print("IP:"..wifi.sta.getip())
       dofile("runtime.lua")
   end
end)
