I created a shield for a esp8266-01 to run two relays but i'm not sure the commands from the webpage are programmed right as any button shows no change in the gpio pins, can someone verify the code is right?
init.lua as follows:

Code: Select all

wifi.setmode(wifi.STATION)

wifi.sta.config("ssid","weppassword")

print('\nSolar PV Controller - ESP8266 Server v1b\n')

tmr.alarm(0, 1000, 1, function()

if wifi.sta.getip() == nil then

print("Connecting to AP...\n")

else

ip, nm, gw=wifi.sta.getip()

macAdd = wifi.sta.getmac();

print("IP Info: \nIP Address: ",ip)

print("Netmask: ",nm)

print("Gateway Addr: ",gw,'\n')

print("Mac Addr: ",macAdd,'\n')

tmr.stop(0)

end

end)

Relay1 = 0

Relay2 = 2

gpio.mode(Relay1, gpio.OUTPUT)

gpio.mode(Relay2, gpio.OUTPUT)

srv=net.createServer(net.TCP)

srv:listen(80,function(conn)

conn:on("receive", function(client,request)

local buf = "";

local _, _, method, path, vars = string.find(request, "([A-Z]+) (.+)?(.+) HTTP");

if(method == nil)then

_, _, method, path = string.find(request, "([A-Z]+) (.+) HTTP");

end

local _GET = {}

if (vars ~= nil)then

for k, v in string.gmatch(vars, "(%w+)=(%w+)&*") do

_GET[k] = v

end

end

buf = buf.."<h1> Solar Relay ESP8266 Web Server</h1>";

buf = buf.."<h2> IOT Project irun4fun 2016</h2>";

buf = buf.."<p>Battery Bank <a href=\"?pin=ON1\"><button>Power ON</button></a>&nbsp;<a href=\"?pin=OFF1\"><button>Power OFF</button></a></p>";

buf = buf.."<p>Solar Array <a href=\"?pin=ON2\"><button>Power ON</button></a>&nbsp;<a href=\"?pin=OFF2\"><button>Power OFF</button></a></p>";

local _on,_off = "",""

if(_GET.pin == "ON1")then

gpio.write(Relay1, gpio.HIGH);

elseif(_GET.pin == "OFF1")then

gpio.write(Relay1, gpio.LOW);

elseif(_GET.pin == "ON2")then

gpio.write(Relay2, gpio.HIGH);

elseif(_GET.pin == "OFF2")then

gpio.write(Relay2, gpio.LOW);

end

client:send(buf);

client:close();

collectgarbage();

end)

end)

Is there anyone here that understands the code well?
