今天小编就为大家分享一篇Python使用线程来接收串口数据的示例，具有很好的参考价值，希望对大家有所帮助。一起跟随小编过来看看吧

如下所示：

				?

									#!/usr/bin/env python

									import serial

									import time

									import 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+=data

									if __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'
