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"
