BeamerControl

Hardware

  • ESP8266
  • MAX3232

Software

Es wird die LUA Firmware vorausgesetzt.

Mit folgendem ESP8266/Programmer kann die folgende Initialisierungsdatei beamer_init.lua geschrieben werden:

print("Booting... Beamer v0.5")
wifi.setmode(wifi.STATION)
wifi.sta.config("WIFI","PASSWORD")

global_c=nil
function netPrint(str)
  if global_c~=nil then
    global_c:send(str)
    global_c:send("\n")
  end
end

function startTelnetServer(dummy)
	s=net.createServer(net.TCP, 180)
	s:listen(2323,function(c)
	global_c=c
	function s_output(str)
	  if(global_c~=nil)
	     then global_c:send(str)
	  end
	end
	node.output(s_output, 0)
	c:on("receive",function(c,l)
	  node.input(l)
	end)
	c:on("disconnection",function(c)
	  node.output(nil)
	  global_c=nil
	end)
	print("Welcome to NodeMcu world.")
	end)
	print("WiFi up and running")
end

m = mqtt.Client("beamer", 120, "", "")
function startMqttServer(c)
	m:on("connect", function(con) print ("MQTT connected") end)
	m:on("offline", function(con) print ("MQTT offline") end)

	m:on("message", function(conn, topic, data)
	  netPrint(topic .. ":" )
	  if data ~= nil then
	    netPrint(topic .. ":" .. data)
	    if data == "OFF" and topic == "/room/beamer/command" then
		netPrint ("Shutdown beamer")
		uart.write(0, "* 0 IR 002\\\r")
	    end
            if data == "ON" and topic == "/room/beamer/command" then
		netPrint ("Start Beamer")
		uart.write(0, "OKOKOKOKOK\\\r")
	    end
	  end
	end)
        m:connect("10.23.XXX.XXX", 1883, 0, function(conn) print("connected") end)

	tmr.alarm(2, 2000, 0, function() 
		m:subscribe("/room/beamer/#",0, function(conn) print("Mqtt - subscribe success") end)
	end)
end


tmr.alarm(1, 1000, 1, function() 
   if wifi.sta.getip()=="0.0.0.0" or wifi.sta.getip() == nil then
      print("Connect AP, Waiting...") 
   else
      print("Connected")
      print( wifi.sta.getip() )
      startTelnetServer()
      startMqttServer()
      tmr.stop(1)
   end
end)

print("Setup UART")
uart.setup(0,9600,8,0,1,0)

-- Send all UART stuff to the debug client
uart.on("data",4, function(data)
	if global_c~=nil then
		global_c:send(data)
	end
end, 0)

Schnittstelle

Der Beamer kann An:

mosquitto_pub -h IP1.IP2.IP3.IP4 -t "/room/beamer/command" -m "OFF"

und aus-geschalten werden:

mosquitto_pub -h IP1.IP2.IP3.IP4 -t "/room/beamer/command" -m "ON"
