TWAI (CAN bus) driver CPU usage?

[brown_x]

Hi

Anyone using TWAI/CAN bus drivers can tell me how much CPU it uses on ESP32 C6?

For me it is not 100% clear how much of the driver functionality is implemented in SW and how much in the TWAI controllers.

On older versions of CAN stack and older versions of ESP32 (the ones with two cores) the CAN stack was eating one core, I want to be sure this is not the case with the C6 and the new drivers renamed TWAI (since I would need the CPU for other CPU intensive tasks).

BR.
