Can anybody provide me a working example of how to make RC522 rfid module to work with ESP32-POE? I have problem with SPI config, no communictaion. I think I'm doing something wrong with custom SPI configuratrion (no default pins on esp32-poe).


You don't have to use the default pins. Any free GPIO can be defined for SPI usage. There is a slight downside of not using the default SPI pins in the speed. Refer to "Timing considerations" part in this article:
