Python使用线程来接收串口数据的示例

#!/usr/bin/env pythonimport serialimport timeimport thread class MSerialPort:	message=''	def __init__(self,port,buand):		self.port=serial.Serial(port,buand)		if not self.port.isOpen():			self.port.open()	def port_open(self):		if not self.port.isOpen():			self.port.open()	def port_close(self):		self.port.close()	def send_data(self,data):		number=self.port.write(data)		return number	def read_data(self):		while True:			data=self.port.readline()			self.message+=dataif __name__=='__main__':	mSerial=MSerialPort('/dev/ttyACM0',9600)	thread.start_new_thread(mSerial.read_data,())	while True:		time.sleep(1)		print mSerial.message		print 'next line'
