'MicroPython ESP32 CanBus

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.

Solution 1:[1]

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.
