Python读取串口数据实现代码

import serial
import time

serialport = serial.Serial()
serialport.port = 'COM3'
serialport.baudrate = 115200
serialport.bytesize = 8
serialport.parity = serial.PARITY_NONE
serialport.stopbits = 1
serialport.timeout = 0.001
serialport.close()
if not serialport.is_open:
	serialport.open()
time.sleep(0.05) #时间设置参考串口传输速率
num = serialport.inWaiting()
while True:
		time.sleep(1)
		while num == 0:
			time.sleep(0.05) #时间设置参考串口传输速率
			num = serialport.inWaiting()
		if num > 0:
			data = serialport.read(num)
			# bytes转str
			print(str(data, 'UTF-8'))
