I've previously used the setup and coded in with Arduino IDE, now flashed/burned the UiFlow2.0.8 Firmware to the Dial and also was able to run some other basic code I did with the UiFlow.

But for some reason it's not possible to initialize the CAN bus. Seems like the M5CAN adapter isn't being recognized (at least thats how I interpret that error).

Does anyone have a hint or basic code using CAN, that can point me into the right direction?
That would be great.

I tried a LOT of different settings for the initialization.

Heres the error I am getting all the time:

Traceback (most recent call last):
  File "<stdin>", line 24, in <module>
  File "<stdin>", line 16, in setup
OSError: (-261, 'ESP_ERR_NOT_FOUND')
