Of course this may or may not work on large scale, I only have ...

SPI Error - MCP2515 not responding

Hello,

I am using a ESP32 and want to connect it with a MCP2515 CAN-Transceiver (I am aware of the integrated transceiver which is already in use).

I have used the same module with an esp8266 already and rewrote the CAN-Driver in IDF.
