node-serialport 详细介绍

node-serialport 是一个 Node.js 的包，用来对串口数据进行读写操作。

基本示例代码：

var SerialPort = require("serialport").SerialPort
    var serialPort = new SerialPort("/dev/tty-usbserial1", {
      baudrate: 57600
    }, false); // this is the openImmediately flag [default is true]
    
    serialPort.open(function (error) {
      if ( error ) {
        console.log('failed to open: '+error);
      } else {
        console.log('open');
        serialPort.on('data', function(data) {
          console.log('data received: ' + data);
        });
        serialPort.write("ls\n", function(err, results) {
          console.log('err ' + err);
          console.log('results ' + results);
        });
      }
    });

罗列所有串口：

var serialPort = require("serialport");
    serialPort.list(function (err, ports) {
      ports.forEach(function(port) {
        console.log(port.comName);
        console.log(port.pnpId);
        console.log(port.manufacturer);
      });
    });

串口配置：

*  `baudRate`
 *  `dataBits`
 *  `stopBits`
 *  `parity`
 *  `rtscts`
 *  `xon`
 *  `xoff`
 *  `xany`
 *  `flowControl`
 *  `bufferSize`
 *  `parser`
 *  `encoding`
 *  `dataCallback`
 *  `disconnectedCallback`
 *  `platformOptions` - sets platform specific options, see below.

目前已有很多项目在使用这个包进行串口处理：

*  [Johnny-Five][] - Firmata based Arduino Framework.
 *  [Cylon.js][] - JavaScript Robotics, By Your Command.
 *  [node-l8smartlight][] ([source][]) A node library to control the L8 Smartlight via Bluetooth or USB port
 *  [firmata][] Talk natively to Arduino using the firmata protocol.
 *  [tmpad][] [source][source 1] - a DIY midi pad using infrared, arduino, and nodejs. [Video][]
 *  [duino][] - A higher level framework for working with Arduinos in node.js.
 *  [Arduino Drinking Game Extravaganza][] - AKA "The Russian" a hexidecimal drinking game for geeks by Uxebu presented at JSConf EU 2011.
 *  [Arduino controlling popcorn.js][] - Controlling a popcorn.js video with an Arduino kit.
 *  [Robotic JavaScript][] - The first live presentation of the node-serialport code set as presented at JSConf EU 2010.
 *  [devicestack][] - This module helps you to represent a device and its protocol.
 *  [reflecta][] A communication protocol that combines Arduino Libraries and NodeJS into an integrated system.
 *  [rc4pt-node][] - Control Popcorntime with an Infrared receiver and Arduino.
