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

二、原文摘自 https://nodemcu.readthedocs.io/en/master/en/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(" Hello, NodeMCU.") 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)
