一、译文

1、NodeMCU文档

NodeMCU是基于ESP8266 WiFi SOC(来自Espressif)的eLua固件，固件基于espressif
non-os SDK并且使用基于spiffs的文件系统。SDK代码库由98.1%的C语言代码和少量的Lua嵌入式代码组成。

NodeMCU固件是与流行的NodeMCU dev kits相配套的项目，现成的开源开发板esp8266-12e芯片。

2、编程模式

NodeMCU的编程模式很像Node.js,只是用的是Lua语言。它是异步和事件驱动的。因此，很多函数又有回调函数作其参数。下面的示例会让你感受到NodeMCU编程就像学习短代码片段。更多的例程可以查看GitHub仓库中的/lua_examples文件夹。

-- 连接到WIFI访问热点
wifi.setmode(wifi.STATION)
wifi.sta.config("SSID", "password")

-- 注册WIFI回调事件
wifi.sta.eventMonReg(wifi.STA_CONNECTING, function(previous_state)
if(previous_state==wifi.STA_GOTIP) then
print("丢失连接.尝试重新连接...")
else
print("连接中")
end
end)

-- 像Arduino一样操作硬件
pin = 1
gpio.mode(pin, gpio.OUTPUT)
gpio.write(pin, gpio.HIGH)
print(gpio.read(pin))

3、准备开始

3.1、构建你所需要模块的固件

3.2、烧写固件到芯片
3.3、上传代码到芯片空间

NodeMCU Documentation

NodeMCU is an eLua based firmware for the ESP8266
WiFi SOC from Espressif. The firmware is based on the Espressif NON-OS SDK and uses a file system based on spiffs. The code
repository consists of 98.1% C-code that glues the thin Lua veneer to the SDK.

The NodeMCU firmware is a companion project to the popular NodeMCU dev kits, ready-made open
source development boards with ESP8266-12E chips.

Programming Model

The NodeMCU programming model is similar to that of Node.js, only in Lua. It is asynchronous and event-driven. Many functions,
therefore, have parameters for callback functions. To give you an idea what a NodeMCU program looks like study the short snippets below. For more extensive examples have a look at the

/lua_examples

folder
in the repository on GitHub.

-- a simple HTTP server
srv = net.createServer(net.TCP)
srv:listen(80, function(conn)
conn:on("receive", function(conn, payload)
print(payload)
conn:send("<h1> Hello, NodeMCU.</h1>")
end)
conn:on("sent", function(conn) conn:close() end)
end)

-- connect to WiFi access point
wifi.setmode(wifi.STATION)
wifi.sta.config("SSID", "password")

-- register event callbacks for WiFi events
wifi.sta.eventMonReg(wifi.STA_CONNECTING, function(previous_state)
if(previous_state==wifi.STA_GOTIP) then
print("Station lost connection with access point. Attempting to reconnect...")
else
print("STATION_CONNECTING")
end
end)

-- manipulate hardware like with Arduino
pin = 1
gpio.mode(pin, gpio.OUTPUT)
gpio.write(pin, gpio.HIGH)
print(gpio.read(pin))
