本文实例讲述了python简单程序读取串口信息的方法。分享给大家供大家参考。具体分析如下:

这段代码需要调用serial模块,通过while循环不断读取串口数据

import time
import serial
ser = serial.Serial( #下面这些参数根据情况修改
  port='COM1',
  baudrate=9600,
  parity=serial.PARITY_ODD,
  stopbits=serial.STOPBITS_TWO,
  bytesize=serial.SEVENBITS
)
data = ''
while ser.inWaiting() > 0:
  data += ser.read(1)
if data != '':
  print data
Copy after login

希望本文所述对大家的Python程序设计有所帮助。
