我是 Python 的初学者。我正在尝试为串行通信创建接口。在我的应用程序中，有 4 个变量，每个变量 2 个字节。我有启动器、命令、源和目标字节。所以，我总共有 4*2+4= 12 个字节的列表。我正在尝试发送此列表并收回。没有控制台错误，但是当我尝试发送列表时，它崩溃了。
ui.SendAll_Button.clicked.connect(lambda: com.send(self.newPackage))
如果我发送没有功能的普通列表，它可以工作。但是newPackage在ValuetoHex函数中，它不起作用。我将代码留在这里：
from PyQt5 import QtCore, QtGui, QtWidgets
import sys
import Max2828_Window as myWindow
import Max2828_WindowEdit as EditModule
import serial
from time import sleep
import struct
con = serial.Serial('COM3', 9600 , timeout = 1)
error_message = [0X65, 0X72, 0X72, 0X6F, 0X72]
starter_byte = 0XAA
source_byte = 0X01
max2828_byte = 0X02
max5866_byte = 0X03
command_byte = 0XBB
byte_1 = 0X00

class Communication():
Package = [starter_byte, source_byte, max2828_byte, command_byte,
byte_1, byte_2, byte_3, byte_4,
byte_5, byte_6, byte_7, byte_8]
def send(self, PackageList):
print(str(PackageList))
con.write(PackageList)
def receive(self,PackageList):
our_buffer = []
counter = 1
while counter <= len(PackageList):
msg = con.read()
our_buffer.append(msg)
print ("received " + str("".join( chr(x) for x in msg)))
print (str(our_buffer))
if len(our_buffer) >= len(PackageList):
our_buffer = None
counter = counter + 1
## sleep(1)
def main(self, PackageList):
self.send(PackageList)
self.receive(PackageList)
##com = Communication()
##com.main()

还有另一个页面，由 PyQt 创建。如果有需要，我可以上传。没有错误消息或控制台错误。单击发送按钮时，只有应用程序崩溃。如果您想对我的代码提出任何建议，请不要犹豫。我是初学者，我想学习。谢谢你。（这是我的第一条消息，从现在开始谢谢你）
