Node.js 串口读写包 node-serialport

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：

• firmata Talk natively to Arduino using the firmata protocol.

• tmpad source - 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.
