Create multi CAN BUS with the library!

[hoanglongrs]

Hello!
The library worked perfectly with my ESP32 S3.

Can you share with me how to create the second CAN BUS on an ESP32 S3?
Example:
I created the first CAN BUS 1 at pin 4, 5, data rate 500 kps with the guide included in the library.
Now I want to create another CAN BUS 2 at pin 6, 7, data rate 250 kps.

Thank!

Hello, It is not possible. Pins actually inteface an embedded CAN controller, and there is only one CAN controller in the ESP32. The only way for getting a second CAN controller is to connect via SPI an external CAN controller, as MCP2515. Pierre
