用python搞个可视化界面：

# -*- coding: utf-8 -*-
import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QLabel, QLineEdit, QPushButton, QMessageBox# 生成 Modbus 格式的 CRC 校验码
def crc16_modbus(data):crc = 0xFFFFfor byte in data:crc ^= bytefor _ in range(8):if (crc & 0x0001):crc >>= 1crc ^= 0xA001else:crc >>= 1crc = format(crc, '04X')# 将高位字节和低位字节交换位置crc = crc[2:] + crc[:2]return crcclass MainWindow(QMainWindow):def __init__(self):super(MainWindow, self).__init__()self.setWindowTitle("CRC校验码计算器")self.setGeometry(100, 100, 300, 200)# 创建界面元素self.label_input = QLabel("请输入数据（以空格分隔）:", self)self.label_input.setGeometry(20, 30, 200, 20)self.input_data = QLineEdit(self)self.input_data.setGeometry(30, 60, 240, 20)self.btn_calculate = QPushButton("计算", self)self.btn_calculate.setGeometry(30, 100, 240, 30)self.btn_calculate.clicked.connect(self.calculate_crc)self.label_output = QLabel("CRC校验码:", self)self.label_output.setGeometry(20, 150, 200, 20)self.output_data = QLabel("", self)self.output_data.setGeometry(120, 150, 150, 20)def calculate_crc(self):# 获取输入数据input_text = self.input_data.text().strip()if not all(c in '0123456789ABCDEFabcdef ' for c in input_text):QMessageBox.warning(self, "警告", "请输入有效的十六进制数！")returninput_list = input_text.split(" ")input_bytes = []for num in input_list:try:input_bytes.append(int(num, 16))  # 将基数改为 16（十六进制）except ValueError:QMessageBox.warning(self, "警告", "请输入有效的十六进制数！")return# 计算 CRCcrc = crc16_modbus(input_bytes)# 更新结果标签self.output_data.setText(crc)if __name__ == "__main__":app = QApplication(sys.argv)window = MainWindow()window.show()sys.exit(app.exec_())
