9-开发板接入小五物联实现远程控制(Wi-Fi模块)
这一节为教程最终版功能演示,现在不必深究,早晚自己全部都会实现的(静静的跟着我学哈)
这一篇主要是让大家尝尝鲜

一,刷固件
因为在网页上构建固件不支持smart,所以自己编译了固件,为了更加方便,自己还把lua的执行程序打包进了bin里面.
给大家各种模块的Flash大小的表
http://wiki.ai-thinker.com/_media/esp8266/esp8266_module_list.png
二,打开刷固件的软件
如果是用的8M的
如果是用的32M的
现在刷固件
其实刷固件都是GPIO0接低电平,然后复位一下,然后就可以刷固件了
先看ESP01刷固件(8M)
拨码开关
然后GPIO0接低电平的时候复位一下模块(ESP8266所有型号都是这样)
或者
然后
复位一下Wi-Fi
开始刷固件
好了
打开使用lua开发的编程软件
复位一下模块
其实就是默认内部有这两个文件
上面是自己写的利用MQTT实现远程升级的程序,好像还没有人这样做过,自己这样做呢,是为了实现每个人都可以随意给自己的设备升级自己的程序,下下节给大家远程升级软件教给大家使用
现在用手机绑定
松开按钮
添加设备
添加设备完成会自动在主界面添加一个设备
因为小五物联面向的是开发者所以默认的程序只是负责远程更新程序的.并没有执行相应动作的程序
大约30S(实际上大约15S)以后程序更新完成,然后设备状态会显示在线
由于小五物联是面向开发者的,所以支持开发者升级自己的程序(下下节教给用户升级自己的程序),
自己云端默认程序控制的端口号是GPIO4 !!!!
默认下载进去的执行程序如下(如果现在看不懂没关系,会用就行,主要是告诉大家跟着自己学,能做到什么程度)
local RelayNowState=0
local RelayNowStateCopy=0
globalSendData ="nil";
local UsartReceiveData="";
local UsartReceiveDataCnt=0;
local UsartReceiveDataCntCopy=0;
RelayPin = 2;
if file.open("switch.lua", "r") then
if file.read() == "relay=1" then
gpio.write(RelayPin,1)
gpio.mode(RelayPin,gpio.OUTPUT)
print("relay=1")
else
gpio.write(RelayPin,0)
gpio.mode(RelayPin,gpio.OUTPUT)
print("relay=0")
end
file.close();
end
local DataDisposeTimerCnt = 0;
local DataDisposeTimer = tmr.create()
DataDisposeTimer:register(10, 1, function()
RelayNowState = gpio.read(RelayPin)
if RelayNowState ~= RelayNowStateCopy then
RelayNowStateCopy = RelayNowState
globalSendData = "switch;relay="..RelayNowState
end
if UsartReceiveDataCnt ~= 0 then
DataDisposeTimerCnt=DataDisposeTimerCnt + 1;
if DataDisposeTimerCnt>=10 then
UsartReceiveDataCnt = 0;
DataDisposeTimerCnt=0;
globalSendData = UsartReceiveData;
UsartReceiveData="";
end
end
if Mymqtt ~= nil and MqttConnectedFlage == true then
if globalSendData ~= "nil" then
Mymqtt:publish(PublishTopic,globalSendData, 0, 0, function(client)
end)
globalSendData = "nil"
end
end
end)
DataDisposeTimer:start()
function MqttDisposeMethod(client, topic, data)
uart.write(0,data)
list = split(data, ';')
if string.find(list[1],"switch") ~= nil then
if list[2] ~= nil then
if file.open(list[1]..".lua", "w+") then
file.write(list[2])
file.close()
end
if list[2] == "relay=0" then
gpio.write(RelayPin,0)
gpio.mode(RelayPin,gpio.OUTPUT)
elseif list[2] == "relay=1" then
gpio.write(RelayPin,1)
gpio.mode(RelayPin,gpio.OUTPUT)
end
globalSendData = data;
end
elseif string.find(list[1],"query") then
if list[2] ~= nil then
if list[2] == "switch" then
RelayNowState = gpio.read(RelayPin)
globalSendData = "switch;relay="..RelayNowState
end
end
end
end
--[[
uart.setup(0, 115200, 8, uart.PARITY_NONE, uart.STOPBITS_1)
uart.on("data",0,function(data)
UsartReceiveData = UsartReceiveData..data;
UsartReceiveDataCnt = UsartReceiveDataCnt + 1;
DataDisposeTimerCnt = 0;
end, 0)]]
因为ESP01并没有GPIO4,可以打开串口调试助手看一下通信的数据
现在说一下GPIO0这个按钮的其它功能
一,上面说了持续按下3,4秒左右是用来绑定设备(指示灯快闪),然后松开
二,持续按下6秒左右,是用来切换执行文件(指示灯慢闪几下后熄灭),然后松开
其实内部程序更新的时候是两套程序在互相切换,就是无论何时都会保留一套,如果更新执行失败
可以切换到以前的程序接着执行.
三,持续按下9秒左右,恢复到最一开始的状态(只保留底层的更新程序,清除其余程序文件)
主要是处理极端,两套程序全有问题了..
大家可以看我写的程序细细品味哈(匠芯还是希望和大家分享知识)
