python串口使用

win10 中 jupyter环境通过pytserial python库 调动串口

import serial
import serial.tools.list_ports

comlist = list(serial.tools.list_ports.comports())

if len(comlist) <= 0:
print “no serial port”
else:
comlist_0 =list(plist[0])
serialName = comlist_0[0]
serialfd = serial.Serial(serialName,9600,timeout = 60)
print “check which port was really used >”,serialfd.name
serialfd.write(‘a’) #通过串口发送数据
