python 调用com,在Python中COM口的调用方法

如下所示：

import serial

import time

t = serial.Serial('com6', 115200) #USB COM number on your PC and the transfer bit rate of the COM port.

print t.portstr #Display the working UART port number on your PC.

n = t.write('logcat -c \r')

n = t.write('ampclient_samples 2 -O 3 /mnt/media_rw/B278-E25A/video_google_clips/New_Webm/bunny_1080P.webm \r')

time.sleep(3)

print "Does the stream output normally? Yes=1 or No=2"

Input = int(raw_input())

if Input == 1:

print "Pass!!!"

n = t.write(chr(0x03)) #Call for Ctrl+C command in UART port

n = t.write('logcat -c \r')

else:

print "Fail!!!"

n = t.write(chr(0x03))

#n = t.write('logcat -v threadtime /r')
