Tkinter处理STM32串口发送的数据（self）
操作步骤：
1、输入正确的com口，然后回车
2、出现下图所示的上位机界面
注意：
使用 data = serial.readline()函数，一直读取到\n才会结束，没有\n就会一直读取
使用下面代码自动获取当前所有串口信息
import serial.tools.list_ports
port_list = list(serial.tools.list_ports.comports())
if len(port_list) == 0:
print('找不到串口')
else:
for i in range(0,len(port_list)):
print(port_list[i])源程序代码：
#import os
#import sys
import serial
from tkinter import *
# import time
jishu1 = 0
def recv(serial): #从串口获取数据
while True:
global jishu1
# print(jishu1)
# if jishu1 < 3: #前三次主要是将数据长度稳定下来
# # data1 = serial.read_all()
# data2 = serial.readline() #读取printf中的数据，遇到\n结束，否则一直读取，会陷入死循环
# # print('data2的长度为：{}'.format(data2))
# data3 = serial.readline() #小技巧：需要读取两次，第一次读取的可能信息不全，不够11个数
# # print('data3的长度为：{}'.format(data3))
# else:
# data3 = serial.readline() # 小技巧：需要读取两次，第一次读取的可能信息不全，不够11个数
# # print(len(data3))
# print(data3)
# print(len(data3))

# if jishu1 == 1000:
# jishu1 = 5
data3 = serial.readline()
data_str = str(data3)
if data_str.count(',') != 10:
data3 = b'0,0,1,0.0,0.00,0.000,0.000,0.00,0.0,0,0.00\n'
