Python操作串口

首先需确保安装了serial模块，如果没安装的话就安装一下python-pyserial。

一个Python实现的串口Echo

import serialimport systry:ser = serial.Serial('/dev/ttyUSB0', 9600)except Exception, e:print 'open serial failed.'exit(1)print 'A Serial Echo Is Running...'while True:# echos = ser.read()ser.write(s)# write to stdout and flush itsys.stdout.write(s)sys.stdout.flush()
