WiFiMCU Introduction

WiFiMCU is developed based on  EMW3165. Run the Lua script directly; operate hardware resource; achieve product prototypes.EMW3165 is a low-power embedded WIFI module, which is developed by the Shanghai MXCHIP Technology Co., Ltd. It incorporates a WiFi RF-Chip and a microcontroller based on STM Cortex-M4.The WiFi module includes a "self-hosted" WiFi network library and application components. In addition, It also provides 2M bytes of out-chip flash, 512K bytes of on-chip flash, 128K bytes of RAM and a rich peripheral resources.

Startup


demo

Build AP
>cfg={ssid='Doit_3165',pwd=''}>wifi.startap(cfg)
WebServer
>cfg={ssid='Doit_3165',pwd=''} wifi.startap(cfg)>function listen_cb(c,ip,port)    c:on("disconnect",function(c) end)    c:on("sent",function(con) end)    c:on("receive",function(c,pl)    c:send([[HTTP/1.1 200 OKServer: WiFiMCUContent-Type:text/htmlContent-Length: 19Connection: close]]..'\r\n\r\n'..[[Welcome to WiFiMCU!]]) end)end>sk=net.new(net.TCP,net.SERVER) sk:listen(80,listen_cb)
Connect Wireless Router

Connect Remote Server
>sk2=net.new(net.TCP,net.CLIENT)>sk2:on("connect",function(c) print("client connected") c:send("From WiFiMCU") end)>sk2:on("receive",function(c,pl) print("receive data:"..pl) c:send("Hello WiFiMCU")end)>sk2:connect(6579,"115.29.109.104")
GPIO Operation
>gpio.mode(6,gpio.INPUT)>print(gpio.read(6))0>print(gpio.read(6))1>gpio.mode(6,gpio.OUTPUT)>gpio.write(6,gpio.HIGH)
Timer Operation
> function tmr_cb() print('tmr1 is called') end> tmr.start(1,1000,tmr_cb)> tmr1 is called
File Operation
> file.open ("test.lua","w+")> file.write("this is a test")> file.close()> file.open ("test.lua","r")> data=file.read()> print(data)this is a test> file.close()>
Self-Start
>file.open ("init.lua","w+")>file.write("print('Hello world!')")>file.close()>mcu.reboot()
