MicroPython ESP32 CanBus
早上好，我一直想在基于 ESP32 的板上使用 machine 库中的 CAN 模块，不幸的是，正如我所想的那样，当我遇到错误时尝试导入它
>>> from machine import CAN
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'CAN'
有什么方法可以在 ESP32 板上启用 CAN 模块吗？我正在关注这个示例，它是这样写的：
[...] ESP32 内置 CAN 控制器，但需要外部添加收发器。 [...]
它指出应该可以在 ESP32 板上使用该模块。
Good morning, I've been wanting to use the CAN module from the machine library on an ESP32 based board, unfortunatelly, as I thought, I'm getting an error when trying to import it
>>> from machine import CAN
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'CAN'
Is there any way to enable the CAN module on an ESP32 board? I'm following this example and it's written:
[...] The ESP32 has a built-in CAN controller, but the transceiver needs to be added externally. [...]
It states that it should be possible to use the module on an ESP32 board.

根据通用的Micropython文档，它似乎具有仅在Pyboard上。
您参考的文档特定于PYCOM板的Micropython固件。
因此，董事会是否支持罐头总线将取决于其随附的硬件和固件。
According to the generic micropython documentation, it seems to have CAN only on the pyboard.
The documentation you reference is specific to the micropython firmware for pycom boards.
So whether a board does or does not support the CAN bus will depend on the hardware and firmware it comes with.
