初学者问题：RASP PI 4 - Python - IOError

如何解决初学者问题：RASP PI 4 - Python - IOError

我正在尝试使用灯光控制建立我自己的 Raspy 安装。

我正在尝试让脚本代码正常工作，以启用灯光控制服务。

我收到一条非常简单的错误消息，但我无法自行修复：

Traceback (most recent call last):
  File "test.py",line 13,in <module>
    bus.write_byte_data(0x39,0x00 | 0x80,0x03)
IOError: [Errno 5] Input/output error

我只想向您展示完整的代码。有谁能帮助我吗？ :)

我无法转换常用工具来解决我使用谷歌遇到的问题。我也只是编写自己的 python 脚本的初学者。通常我会寻找现有的代码（像这样）并为我自己的用例完成它。
