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.
The issue is, that my slave seems dead, i.e. the MISO port is always low.
The shape of my SPI-Frames seems well, but the MISO line seems "floating".
Please see my measurements below with the MISO line detached from the esp32.
Any ideas what this could be?
Thanks in advance.
