六,ESP8266 TCP Client(基于Lua脚本语言)

2021-08-06 14:36:58

今天不知道是不是让我姐挺失望.......很多时候都不知道自己努力的方向对不对,,以后能不能带给家人最美好的期盼......

Init.lua 没啥改变,,就改了一下加载Client.lua

gpio.mode(4,gpio.OUTPUT)
gpio.mode(2,gpio.OUTPUT)
gpio.write(4,1)

tmr.alarm(0, 1000, 1, function()
    gpio.write(4,1-gpio.read(4))
end)

tmr.alarm(1, 3000, 0, function()
    dofile("Client.lua")
end)

新建了一个Client.lua

wifi.setmode(wifi.STATIONAP)

cfg={}
cfg.ssid="Hellow8266"
cfg.pwd="11223344"
wifi.ap.config(cfg)

apcfg={}
apcfg.ssid="qqqqq"
apcfg.pwd="11223344"
wifi.sta.config(apcfg)
wifi.sta.autoconnect(1)

ClientConnectedFlage = 0
TcpConnect = nil
tmr.alarm(1, 1000, 1, function()

    if  ClientConnectedFlage == 0 then
        Client = net.createConnection(net.TCP, 0) 
        Client:connect(8080,"192.168.1.103")

        Client:on("receive", function(Client, data) 
            uart.write(0,data)
        end)
        
        Client:on("connection", function(sck, c) 
            ClientConnectedFlage = 1
            TcpConnect = Client
            print("Link OK")
            tmr.stop(1)

            Client:on("disconnection", function(sck, c) 
                ClientConnectedFlage = 0
                TcpConnect = nil
                tmr.start(1)
            end)
        end)

        if  ClientConnectedFlage == 0 then
            print("Link Error")
        end
    end
end)


uart.on("data",0,function(data) 
    if  TcpConnect ~= nil then
        TcpConnect:send(data)
    end
end, 0)


printip = 0
wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)
    printip = 0
end)


wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
   if printip == 0 then
      print("+IP"..T.IP)
   end
   printip = 1
end)

现在测试

现在创建服务器

发送数据测试

现在断开连接

第一次没有截到网络调试助手的图,模块就连接上了,,所以又断开了一次

现在就用这个读取AD的电压值

命令和回复呢咱就这样规定

现在的init.lua

gpio.mode(4,gpio.OUTPUT)
gpio.mode(2,gpio.OUTPUT)
gpio.write(4,1)

if  adc.force_init_mode(adc.INIT_ADC) then
    node.restart()
    return
end

tmr.alarm(0, 1000, 1, function()
    gpio.write(4,1-gpio.read(4))
end)

tmr.alarm(1, 3000, 0, function()
    dofile("Client.lua")
end)

现在的Client.lua

wifi.setmode(wifi.STATIONAP)

cfg={}
cfg.ssid="Hellow8266"
cfg.pwd="11223344"
wifi.ap.config(cfg)

apcfg={}
apcfg.ssid="qqqqq"
apcfg.pwd="11223344"
wifi.sta.config(apcfg)
wifi.sta.autoconnect(1)

ClientConnectedFlage = 0
TcpConnect = nil
tmr.alarm(1, 1000, 1, function()

    if  ClientConnectedFlage == 0 then
        Client = net.createConnection(net.TCP, 0) 
        Client:connect(8080,"192.168.1.103")

        Client:on("receive", function(Client, data) 
            uart.write(0,data)
            ReadAd(data)
        end)
        
        Client:on("connection", function(sck, c) 
            ClientConnectedFlage = 1
            TcpConnect = Client
            print("Link OK")
            tmr.stop(1)

            Client:on("disconnection", function(sck, c) 
                ClientConnectedFlage = 0
                TcpConnect = nil
                tmr.start(1)
            end)
        end)

        if  ClientConnectedFlage == 0 then
            print("Link Error")
        end
    end
end)


function ReadAd(data)
    if  data == "++MD9" then
        ad = adc.read(0)
        if  TcpConnect ~= nil then
            TcpConnect:send("++MDAD="..ad)
        end
    end
end



uart.on("data",0,function(data) 
    if  TcpConnect ~= nil then
        TcpConnect:send(data)
    end
end, 0)


printip = 0
wifi.eventmon.register(wifi.eventmon.STA_DISCONNECTED, function(T)
    printip = 0
end)


wifi.eventmon.register(wifi.eventmon.STA_GOT_IP, function(T)
   if printip == 0 then
      print("+IP"..T.IP)
   end
   printip = 1
end)

现在测试

对了测试的电压是0-1V 然后分辨率是 1024

我现在接到3.3上

如果数据向加CRC校验,看这篇文章的最后
