我想从我的 arduino 读取数据并将其显示在 tkinter 窗口上，它运行良好，但是当我以每 10 毫秒更快的速度在 arduino 上发送数据时，它会重新查看许多不完整的行，如下所示：

 'Malik']
⚠️ Invalid line, skipped: ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', 'Malik']
⚠️ Invalid line, skipped: ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', 'Malik']
⚠️ Invalid line, skipped: ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', 'Malik']
⚠️ Invalid line, skipped: ['0', '0', '0', '0', '0', '0', '0', '0', '0', '0', '0', 'Malik']

奇怪的是，当我以 10ms 的速度发送时，它可以正常工作，但有时移动窗口时就不行了。希望有人能帮帮我，这是我的代码：

    def read_Serial_Values(self):
        read_Line = ReadLine(ser)
        self.raw_Input = read_Line.readline().decode('utf-8').strip()
        # if self.is_Data_Here():
        #     print("!Overload!")
        #     self.trash = ser.read_all()
        self.raw_Listet_Input = [x for x in self.raw_Input.split(",") if x]
        if len(self.raw_Listet_Input) < 21:
            print("⚠️ Invalid line, skipped:", self.raw_Listet_Input)
            return
        self.Inp_manager.save_Repeating_Input(self.raw_Listet_Input)

    def is_Data_Here(self):
        if ser.in_waiting >0:
            return True
        return False
               

class ReadLine:
    def __init__(self, s):
        self.buf = bytearray()
        self.s = s
    
    def readline(self):
        i = self.buf.find(b"\n")
        if i >= 0:
            r = self.buf[:i+1]
            self.buf = self.buf[i+1:]
            return r
        while True:
            i = max(1, min(2048, self.s.in_waiting))
            data = self.s.read(i)
            i = data.find(b"\n")
            if i >= 0:
                r = self.buf + data[:i+1]
                self.buf[0:] = data[i+1:]
                return r
            else:
                self.buf.extend(data)

我尝试过改变超时时间，但没有任何改变，而且我也改变了程序接收线路的方式。
