The devices are running since 4 years without an issue. Of course this may or may not work on large scale, I only have e...

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. The issue is, that my slave seems dead, i.e. the MISO port is alw...
