Node.js 串口读写包 node-serialport
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：
varSerialPort=require("serialport").SerialPort
varserialPort=newSerialPort("/dev/tty-usbserial1",{
baudrate:57600
},false);//thisistheopenImmediatelyflag[defaultistrue]
serialPort.open(function(error){
if(error){
console.log('failedtoopen:'+error);
}else{
console.log('open');
serialPort.on('data',function(data){
console.log('datareceived:'+data);
});
serialPort.write("ls\n",function(err,results){
console.log('err'+err);
console.log('results'+results);
});
}
});
罗列所有串口：
varserialPort=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：
