Good job!!! Thanks for sharing this dirver. I want use other pins for CAN, but I'm not sure it can work. I have test that GPIO4 and GPIO5 works well. good job!!!! Does it work when I use other pins besides GPIO4 & GPIO5?

Is there any document about CANBUS of ESP32?

CAN also works on other pins. The OLIMEX ESP32-EVB Board e.g. uses Pin 5 and 35.

As far as I know, there is no real documentation for CAN on the ESP32, I build the driver on the SJA100 specification.
