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 http://www.cnblogs.com/yangfengwu/p/7531730.html
五,ESP8266 TCP服务器多连接
TCP 就说道这里
