串口读写(python)

调试中用到的小工具，留存

import time

import serial

import binascii

ser1 = serial.Serial(port='COM7',baudrate=38400,timeout=0)

ser2 = serial.Serial(port='COM5',baudrate=38400,timeout=0)

while (1):

data = ser1.readall()

if(len(data)>0):

print(str(binascii.b2a_hex(data)))

ser2.write(data)

data = ser2.readall()

if(len(data)>0):

# time.sleep(0.01)

#print(binascii.b2a_hex(data))

ser1.write(data)
