ESP8266

A Lua webserver rtunning on the Esp8266 (Thanks to gerardwr from esp8266.com)

if(t==nil) then
  t=12
end
srv=net.createServer(net.TCP) srv:listen(80,function(conn)
    conn:on("receive",function(conn,payload) print(payload)
    conn:send("HTTP/1.1 200 OK\n\n")
    conn:send("<html><body>")
    conn:send("<h1>Erni's ESP8266</h1>
")
    conn:send("TEMP : " .. t .. "
")
    conn:send("NODE.HEAP : " .. node.heap() .. "
")
    conn:send("TMR.NOW : " .. tmr.now() .. "
")
    conn:send("</html></body>")
    conn:on("sent",function(conn) conn:close() end)
  end)
end)

The idea is to test an update of the variable t, that is shown in the page.
I do this from an ATtiny 85 via Serial:

  Serial.print("t=");
  Serial.println(count);

FYI
There are lots of info on the ESP8266 forum:
