Hello
For my futur project I will communicate with many peripheral protocol
I would like to know if possible esp32 can communicate with CanBus interface + ethernet + SD card
CanBus use gpio 21/22 for TX and rx
Ethernet gpio 19/21/22/25 ect...
Gpio 21/22 is use by ethernet and CanBus
Can I change gpio for can bus or not?
Thank you

Yes, you can.

I would like to use Tcan337 FD transceiver it is possible?
Wich port I can use for can bus for replace gpio 21/22?

Possibly. I'm not sure if we tested that specific CAN transceiver.
You can pick any pin that is not otherwise used (e.g. by UART, flash); for TxD, you need a GPIO that is output-capable (any <= GPIO34)
